Proactive control allows us to maneuver a changing environment and individuals are distinct in how they anticipate and approach such changes. Here, we examined how individual differences in personality traits influence cerebral responses to conflict anticipation, a critical process of proactive control. We explored this issue in an fMRI study of the stop signal task, in which the probability of stop signal - p(Stop) - was computed trial by trial with a Bayesian model. Higher p(Stop) is associated with prolonged go trial reaction time, indicating conflict anticipation and proactive control of motor response. Regional brain activations to conflict anticipation were correlated to novelty seeking (NS), harm avoidance (HA), reward dependence, as assessed by the Tridimensional Personality Questionnaire, with age and gender as covariates, in a whole-brain linear regression. Results showed that increased anticipation of the stop signal is associated with activations in the bilateral inferior parietal lobules (IPL), right lateral orbitofrontal cortex (lOFC), middle frontal gyrus (MFG), anterior pre-supplementary motor area (pre-SMA), and bilateral thalamus, with men showing greater activation in the IPL than women. NS correlated negatively to activity in the anterior pre-SMA, right IPL, and MFG/lOFC, and HA correlated negatively to activity in the thalamus during conflict anticipation. In addition, the negative association between NS and MFG/lOFC activity was significant in men but not in women. Thus, NS and HA traits are associated with reduced mobilization of cognitive control circuits when enhanced behavioral control is necessary. The findings from this exploratory study characterize the influence of NS and HA on proactive control and provide preliminary evidence for gender differences in these associations.

Whether personality features affect the development of somatoform disorders and their psychopathologies is an important issue. Aim of this study was to resolve this issue by comparing indicators of psychopathology and personality features in subjects with somatoform disorders and healthy controls. This study recruited 148 subjects with somatoform disorders and 146 healthy controls. The severity of psychopathology was measured with the Patient Health Questionnaire-15 (PHQ-15), Health Anxiety Questionnaire (HAQ), Beck Depression Inventory-II (BDI-II), and Beck Anxiety Inventory (BAI). The Tridimensional Personality Questionnaire (TPQ) was used to assess personality features. Demographic data, psychopathology indicators, and TPQ scores were compared between groups. Correlation and multivariate linear regression analysis were used to identify the personality dimensions or demographic variables associated with psychopathology. The somatoform group had lower novelty seeking (NS) and reward dependence (RD) and higher harm avoidance (HA) and severity of psychopathologies. Multiple regression analysis revealed that fatigability, persistence, gender, and education level were predictive of PHQ-15; HA, educational level, persistence, and dependence were predictive of HAQ; HA, persistence, education level, and NS were predictive of BDII-II; and fatigability, education level, persistence, and anticipatory worry were predictive of BAI. The development of somatoform disorders was associated with fatigability, age, residence location, education level, and attachment. The limitations include heterogeneity of the diagnosis, the high proportion of undifferentiated somatoform disorder, and the cross-sectional study design. HA/fatigability, persistence, and education level are associated with each type of psychopathology. Fatigability is a powerful predictor of somatoform disorder development. Copyright © 2016.

Personality traits have been proposed to affect the risk of sports concussion, but evidence is limited. Cloninger's Tridimensional Personality Questionnaire (TPQ) measures novelty seeking, harm avoidance (HA), and reward dependence traits. The aim of this study was to investigate the relationship between TPQ scores and concussion history in rugby union players. Cross-sectional study. Rugby players from high schools, senior amateur clubs, and professional teams provided a self-reported concussion history and completed the TPQ. Participants reporting no previous concussions formed the control group, while participants reporting concussion formed the case group. A one-way analysis of covariance, with age as a covariate, was used to examine the differences in TPQ scores between groups. Of the 309 participants, 54% reported a minimum of one concussion (junior: 47%; amateur: 52%; professional: 72%). HA scores were significantly higher in junior players without a history of concussion compared to cases (p=0.006). Specifically, the junior control group had higher "anticipatory worry" (p=0.009) and "fear of uncertainty" (p=0.008). In contrast, the professional control group had lower HA scores than cases (p=0.009), while the amateur cohort displayed no differences between control and case groups. This study identified a novel association between HA and concussion in rugby players, adding evidence to the role of personality in a multifactorial risk-model of concussion. The findings suggest that lower HA may lead to increased dangerous play in youth rugby, influencing concussion susceptibility. Contrasting associations in the professional cohort suggest further research is required to understand the role of personality in concussion. Copyright © 2017 Sports Medicine Australia.

Safe from harm: learned, instructed, and symbolic generalization pathways of human threat-avoidance.

Directory of Open Access Journals (Sweden)

Simon Dymond

Full Text Available Avoidance of threatening or unpleasant events is usually an adaptive behavioural strategy. Sometimes, however, avoidance can become chronic and lead to impaired daily functioning. Excessive threat-avoidance is a central diagnostic feature of anxiety disorders, yet little is known about whether avoidance acquired in the absence of a direct history of conditioning with a fearful event differs from directly learned avoidance. In the present study, we tested whether avoidance acquired indirectly via verbal instructions and symbolic generalization result in similar levels of avoidance behaviour and threat-beliefs to avoidance acquired after direct learning. Following fear conditioning in which one conditioned stimulus was paired with shock (CS+ and another was not (CS-, participants either learned or were instructed to make a response that cancelled impending shock. Three groups were then tested with a learned CS+ and CS- (learned group, instructed CS+ (instructed group, and generalized CS+ (derived group presentations. Results showed similar levels of avoidance behaviour and threat-belief ratings about the likelihood of shock across each of the three pathways despite the different mechanisms by which they were acquired. Findings have implications for understanding the aetiology of clinical avoidance in anxiety.

In a synchrotron radiation source (SRS), the interaction between electron beam spectra and Higher Order Modes (HOMs) of RF cavities may give rise to coupled bunch instabilities. These instabilities may limit beam current and beam lifetime. Indus-2 SRS has four RF cavities equipped with precision temperature controller of cooling system and Higher Order Mode Frequency Shifter (HOMFS) to avoid harmful HOMs. Offline (i.e. without beam) and Online (i.e. with beam) measurements, observations and analysis of HOMs have been performed. Some of the Longitudinal modes such as L1 (∼ 950 MHz), L3 (∼ 1432 MHz), L4 (∼ 1521 MHz), L5 (∼1628 MHz) were observed to be quite prominent at specific operating conditions. Based on these studies, harmful HOMs were identified and suitable methods were evolved to avoid these HOMs. Experiments were performed to achieve high beam current in Indus-2. The precision chiller temperatures and HOMFS positions were set as per theoretical estimates and were further optimized in fine steps during experiments. With the optimized settings, beam current around 200 mA at Injection energy (550 MeV) and 157 mA at 2.5 GeV has been successfully achieved. At these settings of RF cavity water temperature and HOMFS, harmful HOMs were within safe limits during regular operation of Indus-2 at 2.5 GeV/100 mA in user mode for more than one year. In this paper, important observations, analysis and experiments to avoid harmful HOMs of RF cavities are presented. (author)

The authors sought to identify risk factors for repeat self-harm and completed suicide over the following year among adults with deliberate self-harm. A national cohort of Medicaid-financed adults clinically diagnosed with deliberate self-harm (N=61,297) was followed for up to 1 year. Repeat self-harm per 1,000 person-years and suicide rates per 100,000 person-years (based on cause of death information from the National Death Index) were determined. Hazard ratios of repeat self-harm and suicide were estimated by Cox proportional hazard models. During the 12 months after nonfatal self-harm, the rate of repeat self-harm was 263.2 per 1,000 person-years and the rate of completed suicide was 439.1 per 100,000 person-years, or 37.2 times higher than in a matched general population cohort. The hazard of suicide was higher after initial self-harm events involving violent as compared with nonviolent methods (hazard ratio=7.5, 95% CI=5.5-10.1), especially firearms (hazard ratio=15.86, 95% CI=10.7-23.4; computed with poisoning as reference), and to a lesser extent after events of patients who had recently received outpatient mental health care (hazard ratio=1.6, 95% CI=1.2-2.0). Compared with self-harm patients using nonviolent methods, those who used violent methods were at significantly increased risk of suicide during the first 30 days after the initial event (hazard ratio=17.5, 95% CI=11.2-27.3), but not during the following 335 days. Adults treated for deliberate self-harm frequently repeat self-harm in the following year. Patients who use a violent method for their initial self-harm, especially firearms, have an exceptionally high risk of suicide, particularly right after the initial event, which highlights the importance of careful assessment and close follow-up of this group.

Over the past decade, the benefits and harms balance of breast cancer (BC) screening has been widely debated. To elicit women's trade-offs between the benefits and harms of BC screening and to analyze the main determinants of these trade-offs. A discrete-choice experiment with seven attributes depicting BC screening programs including varying levels of BC mortality, overdiagnosis, and false-positive result was used. Eight hundred twelve women aged 40 to 74 years with no personal history of BC recruited by a survey institute and representative of the French general population (age, socioeconomic level, and geographical location) completed the discrete-choice experiment. Preference heterogeneity was investigated using generalized multinomial logit models from which individual trade-offs were derived, and their main determinants were assessed using generalized linear models. Screening acceptance rates under various benefits and harms ratios were simulated on the basis of the distribution of individual preferences. The women would be willing to accept on average 14.1 overdiagnosis cases (median = 9.6) and 47.8 false-positive results (median = 27.2) to avoid one BC-related death. After accounting for preference heterogeneity, less than 50% of women would be willing to accept 10 overdiagnosis cases for one BC-related death avoided. Screening acceptance rates were higher among women with higher socioeconomic level and lower among women with poor health. Women are sensitive to both the benefits and the harms of BC screening and their preferences are highly heterogeneous. Our study provides useful results for public health authorities and clinicians willing to improve their recommendations of BC screening on the basis of women's preferences.

Harmed patients gaining voice: challenging dominant perspectives in the construction of medical harm and patient safety reforms.

Science.gov (United States)

Ocloo, Josephine Enyonam

2010-08-01

Patient safety is a central issue in healthcare. In the United Kingdom, where there is more accurate information on National Health Service (NHS) hospitals than on primary care or the private sector, the evidence on adverse incidents shows that avoidable medical harm is a major concern. This paper looks at the occurrence of medical harm and argues that in the construction of patient safety reforms, it is important to be aware of alternative narratives about issues of power and accountability from harmed patients and self-help groups, that challenge dominant perspectives on the issues. The paper draws upon evidence from two sources. First, the paper draws on experiences of self-help groups set up as a result of medical harm and part of a campaigning network, where evidence was gathered from 14 groups over more than 2 years. In addition, data were obtained from 21 individuals affected by harm that attended a residential workshop called the Break Through Programme; 18 questionnaires were completed from participants and a written narrative account of their experiences and observational data were gathered from a range of workshop sessions. Looking at the issues from harmed patients' perspectives, the research illustrates that a model of medical harm focussing predominantly upon the clinical markers and individual agency associated with a medical model operates to obscure a range of social processes. These social processes, connected to the power and dominance of the medical profession and the activities of a wider state, are seen to be a major part of the construction of harm that impacts upon patients, which is further compounded by its concealment. Understanding the experiences of harmed patients is therefore seen as an important way of generating knowledge about the medical and social processes involved in harm, that can lead to a broader framework for addressing patient safety.

Does the amygdala response correlate with the personality trait 'harm avoidance' while evaluating emotional stimuli explicitly?

Science.gov (United States)

2014-05-07

The affective personality trait 'harm avoidance' (HA) from Cloninger's psychobiological personality model determines how an individual deals with emotional stimuli. Emotional stimuli are processed by a neural network that include the left and right amygdalae as important key nodes. Explicit, implicit and passive processing of affective stimuli are known to activate the amygdalae differently reflecting differences in attention, level of detailed analysis of the stimuli and the cognitive control needed to perform the required task. Previous studies revealed that implicit processing or passive viewing of affective stimuli, induce a left amygdala response that correlates with HA. In this new study we have tried to extend these findings to the situation in which the subjects were required to explicitly process emotional stimuli. A group of healthy female participants was asked to rate the valence of positive and negative stimuli while undergoing fMRI. Afterwards the neural responses of the participants to the positive and to the negative stimuli were separately correlated to their HA scores and compared between the low and high HA participants. Both analyses revealed increased neural activity in the left laterobasal (LB) amygdala of the high HA participants while they were rating the positive and the negative stimuli. Our results indicate that the left amygdala response to explicit processing of affective stimuli does correlate with HA.

There is evidence to suggest that both psychological characteristics and stressful life events are contributory factors in deliberate self-harm among young people. These links, and the possibility of a dose-response relationship between self-harm and both psychological health and life events, were investigated in the context of a seven-country school-based study. Over 30,000, mainly 15 and 16 year olds, completed anonymous questionnaires at secondary schools in Belgium, England, Hungary, Ireland, the Netherlands, Norway and Australia. Pupils were asked to report on thoughts and episodes of self-harm, complete scales on depression and anxiety symptoms, impulsivity and self-esteem and indicate stressful events in their lives. Level and frequency of self-harm was judged according to whether they had thought about harming themselves or reported single or multiple self-harm episodes. Multinomial logistic regression assessed the extent to which psychological characteristics and stressful life events distinguished between adolescents with different self-harm histories. Increased severity of self-harm history was associated with greater depression, anxiety and impulsivity and lower self-esteem and an increased prevalence of all ten life event categories. Female gender, higher impulsivity and experiencing the suicide or self-harm of others, physical or sexual abuse and worries about sexual orientation independently differentiated single-episode self-harmers from adolescents with self-harm thoughts only. Female gender, higher depression, lower self-esteem, experiencing the suicide or self-harm of others, and trouble with the police independently distinguished multiple- from single-episode self-harmers. The findings reinforce the importance of psychological characteristics and stressful life events in adolescent self-harm but nonetheless suggest that some factors are more likely than others to be implicated.

Long-term avoidance memory formation is associated with a transient increase in mushroom body synaptic complexes in leaf-cutting ants

Full Text Available Long-term behavioral changes related to learning and experience have been shown to be associated with structural remodeling in the brain. Leaf-cutting ants learn to avoid previously preferred plants after they have proved harmful for their symbiotic fungus, a process that involves long-term olfactory memory. We studied the dynamics of brain microarchitectural changes after long-term olfactory memory formation following avoidance learning in Acromyrmex ambiguus. After performing experiments to control for possible neuronal changes related to age and body size, we quantified synaptic complexes (microglomeruli, MG in olfactory regions of the mushroom bodies (MB at different times after learning. Long-term avoidance memory formation was associated with a transient change in MG densities. Two days after learning, MG density was higher than before learning. At days 4 and 15 after learning — when ants still showed plant avoidance — MG densities had decreased to the initial state. The structural reorganization of MG triggered by long-term avoidance memory formation clearly differed from changes promoted by pure exposure to and collection of novel plants with distinct odors. Sensory exposure by the simultaneous collection of several, instead of one, non-harmful plant species resulted in a decrease in MG densities in the olfactory lip. We hypothesize that while sensory exposure leads to MG pruning in the MB olfactory lip, the formation of long-term avoidance memory involves an initial growth of new MG followed by subsequent pruning.

2013-12-01

Childhood physical abuse (CPA), non-suicidal self-harm and attempted suicide are all highly prevalent amongst injecting drug users (IDU). This paper reported on the association of CPA with self-harm and attempted suicide. Cross-sectional study, with 300 IDU administered a structured interview examining the prevalence of CPA, non-suicidal self-harm and suicide attempts. CPA was reported by 74.3%, and severe CPA by 40.3%. A history of non-suicidal self-harm was reported by 23.7%, and 25.7% had attempted suicide. Non-suicidal self-harm preceded the suicide attempt in 83.3% of cases where both had occurred. Independent correlates of non-suicidal self-harm were: female gender (OR 3.62), avoided home due to conflict (OR 2.28) and more extensive polydrug use (OR 1.32). Independent correlates of attempted suicide were: severe CPA (OR 3.18), frequent CPA (OR 2.54), avoided home due to conflict (OR 3.95), female gender (OR 2.99), a positive screen for Conduct Disorder (OR 3.53), and more extensive polydrug use (OR 1.52). Those presenting to treatment agencies are highly likely to have a history of CPA, that may still influence their behaviours. Screening for histories of CPA and non-suicidal self-harm appears warranted when determining suicide risk for this population. At the population level, reductions in the rate of CPA, could possibly reduce the rate of subsequent suicidality. Copyright © 2013 Elsevier Ireland Ltd. All rights reserved.

Individual Differences in Approach-Avoidance Aptitude: Some Clues from Research on Parkinson’s Disease

Full Text Available Approach and avoidance are two basic behavioral aptitudes of humans whose correct balance is critical for successful adaptation to the environment. As the expression of approach and avoidance tendencies may differ significantly between healthy individuals, different psychobiological factors have been posited to account for such variability. In this regard, two main issues are still open that refers to i the role played by dopamine neurotransmission and ii the possible influence of cognitive characteristics, particularly executive functioning. The aim of the present paper was to highlight the contribution of research on Parkinson’s disease (PD to our understanding of the above issues. In particular, we here reviewed PD literature to clarify whether neurobiological and neuropsychological modifications due to PD are associated to changes in approach-avoidance related personality features. Available data indicate that PD patients may show and approach-avoidance imbalance as documented by lower novelty-seeking and higher harm-avoidance behaviors, possibly suggesting a relationship with neurobiological and neurocognitive PD-related changes. However, the literature that directly investigated this issue is still sparse and much more work is needed to better clarify it.

With correction for mood state, total harm avoidance (HA was higher than unaffected in both MDD and BP groups, but the mood disorder groups did not differ from each other. However, BP1 individuals had higher self-transcendence (ST than those with MDD and unaffected relatives. HA may reflect a trait marker of mood disorders whereas high ST may be specific to BP. As ST is heritable, genes that affect ST may be of relevance for vulnerability to BP.

This study describes the prevalence, clinical characteristics, and gender profile of self-harm in a cross-sectional sample of 388 patients with schizophrenia spectrum disorders. All patients were interviewed and assessed with respect to lifetime self-harm and relevant clinical variables. An overall of 49% of the patients reported self-harm which was associated with female gender, having had a depressive episode, younger age at psychosis onset, alcohol abuse or dependence, current suicidality, awareness of illness, and low adherence to prescribed medication. Higher awareness of having a mental disorder was associated with self-harm in men only, while emotional dysregulation was associated with self-harm in women only. We conclude that while self-harm in patients with schizophrenia spectrum disorders is highly prevalent in both genders, risk factors in men and women differ in several important ways.

Self-harm.

Science.gov (United States)

Skegg, Keren

The term self-harm is commonly used to describe a wide range of behaviours and intentions including attempted hanging, impulsive self-poisoning, and superficial cutting in response to intolerable tension. As with suicide, rates of self-harm vary greatly between countries. 5-9% of adolescents in western countries report having self-harmed within the previous year. Risk factors include socioeconomic disadvantage, and psychiatric illness--particularly depression, substance abuse, and anxiety disorders. Cultural aspects of some societies may protect against suicide and self-harm and explain some of the international variation in rates of these events. Risk of repetition of self-harm and of later suicide is high. More than 5% of people who have been seen at a hospital after self-harm will have committed suicide within 9 years. Assessment after self-harm includes careful consideration of the patient's intent and beliefs about the lethality of the method used. Strong suicidal intent, high lethality, precautions against being discovered, and psychiatric illness are indicators of high suicide risk. Management after self-harm includes forming a trusting relationship with the patient, jointly identifying problems, ensuring support is available in a crisis, and treating psychiatric illness vigorously. Family and friends may also provide support. Large-scale studies of treatments for specific subgroups of people who self-harm might help to identify more effective treatments than are currently available. Although risk factors for self-harm are well established, aspects that protect people from engaging in self-harm need to be further explored.

Moral Distress, Workplace Health, and Intrinsic Harm.

Science.gov (United States)

Weber, Elijah

2016-05-01

Moral distress is now being recognized as a frequent experience for many health care providers, and there's good evidence that it has a negative impact on the health care work environment. However, contemporary discussions of moral distress have several problems. First, they tend to rely on inadequate characterizations of moral distress. As a result, subsequent investigations regarding the frequency and consequences of moral distress often proceed without a clear understanding of the phenomenon being discussed, and thereby risk substantially misrepresenting the nature, frequency, and possible consequences of moral distress. These discussions also minimize the intrinsically harmful aspects of moral distress. This is a serious omission. Moral distress doesn't just have a negative impact on the health care work environment; it also directly harms the one who experiences it. In this paper, I claim that these problems can be addressed by first clarifying our understanding of moral distress, and then identifying what makes moral distress intrinsically harmful. I begin by identifying three common mistakes that characterizations of moral distress tend to make, and explaining why these mistakes are problematic. Next, I offer an account of moral distress that avoids these mistakes. Then, I defend the claim that moral distress is intrinsically harmful to the subject who experiences it. I conclude by explaining how acknowledging this aspect of moral distress should reshape our discussions about how best to deal with this phenomenon. © 2015 John Wiley & Sons Ltd.

The cost of harmful alcohol use in South Africa.

2014-02-01

The economic, social and health costs associated with alcohol-related harms are important measures with which to inform alcohol management policies and laws. This analysis builds on previous cost estimates for South Africa. We reviewed existing international best-practice costing frameworks to provide the costing definitions and dimensions. We sourced data from South African costing literature or, if unavailable, estimated costs using socio-economic and health data from secondary sources. Care was taken to avoid possible causes of cost overestimation, in particular double counting and, as far as possible, second-round effects of alcohol abuse. The combined total tangible and intangible costs of alcohol harm to the economy were estimated at 10 - 12% of the 2009 gross domestic product (GDP). The tangible financial cost of harmful alcohol use alone was estimated at R37.9 billion, or 1.6% of the 2009 GDP. The costs of alcohol-related harms provide a substantial counterbalance to the economic benefits highlighted by the alcohol industry to counter stricter regulation. Curtailing these costs by regulatory and policy interventions contributes directly and indirectly to social well-being and the economy. CONCLUSIONS; Existing frameworks that guide the regulation and distribution of alcohol frequently focus on maximising the contribution of the alcohol sector to the economy, but should also take into account the associated economic, social and health costs. Current interventions do not systematically address the most important causes of harm from alcohol, and need to be informed by reliable evidence of the ongoing costs of alcohol-related harms.

Exploring the relationship between posttraumatic stress disorder and deliberate self-harm: the moderating roles of borderline and avoidant personality disorders.

Gratz, Kim L; Tull, Matthew T

2012-08-30

Despite increasing evidence for an association between posttraumatic stress disorder (PTSD) and deliberate self-harm (DSH), few studies have examined the factors that moderate this association or the impact of co-occurring personality disorders among individuals with PTSD on DSH frequency. Given the high rates of co-occurrence between PTSD and two personality disorders of particular relevance to DSH, borderline personality disorder (BPD) and avoidant personality disorder (AVPD), this study examined the moderating role of these personality disorders in the association between PTSD and DSH frequency among a sample of substance use disorder patients (N=61). Patients completed structured clinical interviews assessing PTSD, BPD, and AVPD and a questionnaire assessing DSH. Results revealed more frequent DSH among patients with (vs. without) PTSD and provided evidence for the moderating role of AVPD in this association. Specifically, results revealed heightened levels of DSH only among PTSD patients with co-occurring AVPD. Findings are consistent with past research demonstrating that the presence of co-occurring AVPD among patients with other Axis I and II disorders is associated with worse outcomes, and highlight the importance of continuing to examine the moderating role of AVPD in the association between PTSD and a variety of health-risk behaviors.

Aversive emotional reactions to real or imagined social harms infuse moral judgment and motivate prosocial behavior. Here, we show that the neurotransmitter serotonin directly alters both moral judgment and behavior through increasing subjects' aversion to personally harming others. We enhanced serotonin in healthy volunteers with citalopram (a selective serotonin reuptake inhibitor) and contrasted its effects with both a pharmacological control treatment and a placebo on tests of moral judgment and behavior. We measured the drugs' effects on moral judgment in a set of moral 'dilemmas' pitting utilitarian outcomes (e.g., saving five lives) against highly aversive harmful actions (e.g., killing an innocent person). Enhancing serotonin made subjects more likely to judge harmful actions as forbidden, but only in cases where harms were emotionally salient. This harm-avoidant bias after citalopram was also evident in behavior during the ultimatum game, in which subjects decide to accept or reject fair or unfair monetary offers from another player. Rejecting unfair offers enforces a fairness norm but also harms the other player financially. Enhancing serotonin made subjects less likely to reject unfair offers. Furthermore, the prosocial effects of citalopram varied as a function of trait empathy. Individuals high in trait empathy showed stronger effects of citalopram on moral judgment and behavior than individuals low in trait empathy. Together, these findings provide unique evidence that serotonin could promote prosocial behavior by enhancing harm aversion, a prosocial sentiment that directly affects both moral judgment and moral behavior.

Several lines of evidence suggest that a disturbance of serotonin neuronal pathways may contribute to the pathogenesis of anorexia nervosa (AN) and bulimia nervosa (BN). This study applied positron emission tomography (PET) to investigate the brain serotonin 2A (5-HT2A) receptor, which could contribute to disturbances of appetite and behavior in AN and BN. To avoid the confounding effects of malnutrition, we studied 10 women recovered from bulimia-type AN (REC AN–BN, >1 year normal weight, regular menstrual cycles, no binging, or purging) compared with 16 healthy control women (CW) using PET imaging and a specific 5-HT2A receptor antagonist, [18F]altanserin. REC AN–BN women had significantly reduced [18F]altanserin binding potential relative to CW in the left subgenual cingulate, the left parietal cortex, and the right occipital cortex. [18F]altanserin binding potential was positively related to harm avoidance and negatively related to novelty seeking in cingulate and temporal regions only in REC AN–BN subjects. In addition, REC AN–BN had negative relationships between [18F]altanserin binding potential and drive for thinness in several cortical regions. In conclusion, this study extends research suggesting that altered 5-HT neuronal system activity persists after recovery from bulimia-type AN, particularly in subgenual cingulate regions. Altered 5-HT neurotransmission after recovery also supports the possibility that this may be a trait-related disturbance that contributes to the pathophysiology of eating disorders. It is possible that subgenual cingulate findings are not specific for AN–BN, but may be related to the high incidence of lifetime major depressive disorder diagnosis in these subjects. PMID:15054474

Secondhand smoke (SHS) exposure is a serious public health threat worldwide; in the developing world there are less serious efforts towards controlling women's and children's exposure to SHS. Knowledge, attitudes and avoidance practices among Jordanian women have never been thoroughly studied. The purpose of this study was to assess the knowledge, attitudes, and avoidance behavior towards SHS exposure among employed Jordanian women with higher education. A survey was conducted among employed Jordanian women at two universities. A total of 209 women were included in the analysis. Two questionnaires regarding SHS exposure were used to measure knowledge, attitudes and avoidance practices. Most respondents were regularly exposed to SHS in various locations during daily life, even though they were very knowledgeable about the dangers of SHS exposure for women and children. However, the subject's attitudes and avoidance behavior did not reflect the level of knowledge about SHS risks. The results suggests there is a large discrepancy between SHS exposure, knowledge, attitudes and avoidance behavior among highly educated Jordanian women that is likely influenced by culture and traditional gender roles. Public health initiatives are needed in Jordan to address public policy, institutional practices and to empowerment of women to reduce SHS exposure.

On balance: weighing harms and benefits in fundamental neurological research using nonhuman primates.

Science.gov (United States)

Arnason, Gardar; Clausen, Jens

2016-06-01

One of the most controversial areas of animal research is the use of nonhuman primates for fundamental research. At the centre of the controversy is the question of whether the benefits of research outweigh the harms. We argue that the evaluation of harms and benefits is highly problematic. We describe some common procedures in neurological research using nonhuman primates and the difficulties in evaluating the harm involved. Even if the harm could be quantified, it is unlikely that it could be meaningfully aggregated over different procedures, let alone different animals. A similar problem arises for evaluating benefits. It is not clear how benefits could be quantified, and even if they could be, values for different aspects of expected benefits cannot be simply added up. Sorting harms and benefits in three or four categories cannot avoid the charge of arbitrariness and runs the risk of imposing its structure on the moral decision. The metaphor of weighing or balancing harms and benefits is inappropriate for the moral decision about whether to use nonhuman primates for research. Arguing that the harms and benefits in this context are incommensurable, we suggest describing the moral consideration of harms and benefits as a coherent trade-off. Such a decision does not require commensurability. It must be well-informed about the suffering involved and the potential benefits, it must be consistent with the legal, regulatory and institutional framework within which it is made, and it must cohere with other judgments in relevant areas.

Low IQ is associated with an increased risk of suicide and suicide attempt in adults, but less is known about the relationship between IQ and aspects of suicidal/self-harm behaviours in adolescence. We used data from the Avon Longitudinal Study of Parents and Children (ALSPAC), a population-based prospective UK cohort. Binomial and multinomial logistic regression models were used to examine the association of IQ measured at age 8 with suicide-related outcomes amongst 4810 adolescents aged 16-17 years. There was some evidence that associations differed in boys and girls (p values for interaction ranged between 0.06 and 0.25). In boys higher IQ was associated with increased risk of suicidal thoughts (adjusted odds ratio per 10 point increase in IQ score=1.14, 95% Confidence Interval [CI] 1.01-1.28) and suicidal plans (1.15, 95% CI 0.93-1.43), although statistical evidence for the latter association was limited. There was also evidence for an association with non-suicidal self-harm (1.24, 95% CI 1.08-1.45) but not suicidal self-harm (1.04, 95% CI 0.86-1.25). In girls higher IQ was associated with increased risk of non-suicidal self-harm (1.11, 95% CI 1.02-1.22) but not suicidal thoughts, suicidal plans or suicidal self-harm. Loss to follow up and questionnaire non-response may have led to selection bias. In contrast to previous studies of IQ-suicide associations in adults, we found that higher IQ was associated with an increased risk of non-suicidal self-harm in male and female adolescents and suicidal thoughts in males. Associations of IQ with self-harm differed for self-harm with and without suicidal intent, suggesting that the aetiology of these behaviours may differ. © 2013 Elsevier B.V. All rights reserved.

What’s the Harm? Harms in Research with Adults with Intellectual Disability

McDonald, Katherine E.; Conroy, Nicole E.; Olick, Robert S.

2017-01-01

Scientific advances can improve the lives of adults with intellectual disability, yet concerns that research participation may impose harm impede scientific progress. What counts as harmful can be subjective and perceptions of harm may vary among stakeholders. We studied perspectives on the harmfulness of research events among adults with intellectual disability, family members and friends, disability service providers, researchers, and Institutional Review Board members. We found considerable variance. For example, adults with intellectual disability see exclusion from research as more harmful, but most psychosocial harms as less significant than others. All stakeholders agree that having someone else make the participation decision is harmful. Findings provide insights into the concept of harm and ethical research with adults with intellectual disability. PMID:28095059

Characteristics and trends of self-harming behaviour in young people.

Science.gov (United States)

Cleaver, Karen

Deliberate self-harm is recognized as a serious public health issue in young people. There is evidence that young people who self-harm are more likely to repeat self-harm, and this in turn increases their risk of completed suicide. Prevalence studies have identified that the rate of self-harm among young people is on the increase, information largely based on data arising from review and analysis of hospital attendances. However, community-based studies indicate that the prevalence is much higher, with those seen in emergency departments representing the 'tip of the iceberg' (Hawton and Rodham, 2006). Young people's motives for self-harm are discussed, as are research findings which indicate that nurses can have negative attitudes towards patients who self-harm. The article considers the implications of this for young people and identifies areas for future research.

An internet survey involving 1,558 respondents allowed childhood cruelty, using the Children and Animals Inventory (CAI, to be investigated in the context of other violent behaviours in the child’s home. The homes of children who did no harm animals were less violent than the homes of children who harmed animals. Consistent with other studies, males were more likely to harm animals than females. Males were more likely than females to harm sentient animals. While the use of violence to train children was not associated with a higher CAI score, domestic violence and the presence of a gun in the home were associated with a higher CAI score.

It is crucial for animal survival to detect dangers such as predators. A good indicator of dangers is injury of conspecifics. Here we show that fluids released from injured conspecifics invoke acute avoidance in both free-living and parasitic nematodes. Caenorhabditis elegans avoids extracts from closely related nematode species but not fruit fly larvae. The worm extracts have no impact on animal lifespan, suggesting that the worm extract may function as an alarm instead of inflicting physical harm. Avoidance of the worm extract requires the function of a cGMP signaling pathway that includes the cGMP-gated channel TAX-2/TAX-4 in the amphid sensory neurons ASI and ASK. Genetic evidence indicates that the avoidance behavior is modulated by the neurotransmitters GABA and serotonin, two common targets of anxiolytic drugs. Together, these data support a model that nematodes use a nematode-specific alarm pheromone to detect conspecific injury. Copyright © 2017 by the Genetics Society of America.

To gain a better understanding of self-harm, a 28-year-old female patient and a 19-year-old female patient with self-harming behaviour are presented. The first patient refused treatment of cut wounds when the doctor enquired about the reason for self-harm. The second patient was referred for mental health care. These cases illustrate the complexity of this behaviour for the patient and the caregiver. Self-harm is often a symbol of underlying problems and serves multiple psychological functions. It is mostly used by patients to cope with unbearable emotions for which they have no other solution. The self-harm invokes different feelings in caregivers which tend to influence the attitude of the caregiver towards the patient. It is very important that caregivers are aware of their feelings and use them professionally. People who self-harm should not be judged, but treated respectfully and attention should be paid to their suffering.

To investigate the episodes and influencing factors on self-harm and to explore the relationship between self-harm episodes and suicidal psychology and behaviors in college students. Four universities were selected using cluster sampling method in Anqing city and Chaohu city. Totally, 2713 college students completed this survey. Data were analyzed by Pearson Chi-square and logistic regression. In the last six months, rates of highly lethal self-harm, less lethal self-harm with visible tissue damage, self-injury without visible tissue damage, self-harmful behaviors with latency damage, other self-harmful behaviors with menticide were 1.9%, 5.5%, 15.3%, 21.2% and 17.0% respectively. The total rate of self-harm was 31.3%. 73.1% of the students with self harmful experiences had the above mentioned behaviors more than 3 times in the last six months. The top 3 reasons for taking self-harm actions were: having learning problems (43.1%), failed love affairs (25.0%) and having conflicts with others (23.9%). There were different influencing factors among different kinds of self-harm episodes. Depression was the risk factor of self-harm. The higher score of having high self-esteem was the protective factor of all kinds of self-harm actions except highly lethal ones. Higher score of difficulties in identifying feelings was one of the risk factors. The rates of suicidal psychology and behaviors in students with self-harm were significantly higher than those in students without those behaviors. Result from linear χ(2) test indicated that the graveness of tissue damage of self-harm was higher along with the rates of suicidal psychology and behaviors (P self-esteem was the protective factor related to most of the self-harm cases.

Between-participants on-line experiment, with random assignment to view: (a) alcohol product advertisements (ALC control); (b) advertisements unrelated to alcohol (NON-ALC control); (c) advertisements featuring short-term harms (STH) of alcohol; (d) advertisements featuring STH plus a STH guideline (STH+G); (e) advertisements featuring long-term harms (LTH); or (f) advertisements featuring LTH plus a LTH guideline (LTH+G). Australia, 2016. A total of 3718 drinkers aged 18-64 years (48.5% male). Post-exposure likelihood that participants provided a correct estimate of drinking levels associated with short- and long-term harms; post-exposure intentions to avoid alcohol or reduce consumption. After exposure to STH+G or LTH+G advertisements, participants were more likely to estimate correctly rather than overestimate drinking levels associated with harm, compared with those exposed to STH (P < 0.001) and LTH advertisements without guidelines, respectively (P = 0.019) and ALC control (STH+G, P < 0.001; LTH+G, P < 0.001) and NON-ALC control conditions (STH+G, P < 0.001; LTH+G, P = 0.011). Drinkers exposed to STH conditions were more likely to intend to reduce next-week alcohol consumption than those exposed to ALC control (both P < 0.001) and NON-ALC control conditions (STH, P = 0.001; STH+G, P < 0.001); a similar pattern was observed for intentions to avoid alcohol. Drinkers exposed to LTH conditions were also more likely than drinkers exposed to ALC or NON-ALC controls to intend to avoid and reduce alcohol in the next week. Additionally, drinkers exposed to LTH+G were more likely to intend to reduce drinking than those exposed to LTH advertisements without guidelines (P = 0.022).

The causes of deliberate self- harm, risk factors, the relationship between mental disorders and treatment strategies are not fully known. Deliberate self- harm can be observed together with psychiatric disorders such as borderline personality disorder, histrionic personality disorder, eating disorders and mood disorders. Also, deliberate self-harm must be distinguished from suicidal behavior. Psychologi-cal trauma has been suggested as a risk factor for deliberate self- harm behavior. Trauma and traumatic events have long been associated with deliberate self- harm behavior.

Recently, self-injury is drawing the attention of researchers and clinicians. The purpose of this study was to investigate the prevalence and psychological characteristics of adolescents who engage in self-harm and to examine the risk factors for engaging in this harmful behavior among Korean mid-adolescents. Participants were 784 adolescents aged 13-15 years. They completed self-report questionnaires that assessed (1) Non-Suicidal Self-Injury: the Self-Harm Questionnaire, Toronto Alexithymia Scale; (2) depression: Children's Depression Inventory; (3) adolescent-parent relationship: Parental Bonding Instrument; (4) peer attachment: Inventory of Parent and Peer Attachment; and (5) academic stress. Overall, 12.4% (n=97) of participants reported engaging in self-destructive behavior at least once in their lives. The primary reason for engaging in self-harm was to regulate negative emotions such as anger and sadness. As expected, the self-harm group showed statistically significant higher levels of academic stress, alexithymia, depression, and poor relationships with their parents and peers. Stepwise multiple regression analysis showed that alexithymia, depression, and peer relations were significant predictors of self-harming behavior. Given that the primary reason for engaging in self-harm is to cope with negative emotions, mental health professionals in school settings should regularly evaluate self-injurious behavior and provide prevention programs for adolescents at risk.

To evaluate the accuracy with which physical therapists identify fear-avoidance beliefs in patients with low back pain by comparing therapist ratings of perceived patient fear-avoidance to the Fear-Avoidance Beliefs Questionnaire (FABQ), Tampa Scale of Kinesiophobia 11-item (TSK-11), and Pain Catastrophizing Scale (PCS). To compare the concurrent validity of therapist ratings of perceived patient fear-avoidance and a 2-item questionnaire on fear of physical activity and harm, with clinical measures of fear-avoidance (FABQ, TSK-11, PCS), pain intensity as assessed with a numeric pain rating scale (NPRS), and disability as assessed with the Oswestry Disability Questionnaire (ODQ). The need to consider psychosocial factors for identifying patients at risk for disability and chronic low back pain has been well documented. Yet the ability of physical therapists to identify fear-avoidance beliefs using direct observation has not been studied. Eight physical therapists and 80 patients with low back pain from 3 physical therapy clinics participated in the study. Patients completed the FABQ, TSK-11, PCS, ODQ, NPRS, and a dichotomous 2-item fear-avoidance screening questionnaire. Following the initial evaluation, physical therapists rated perceived patient fear-avoidance on a 0-to-10 scale and recorded 2 influences on their ratings. Spearman correlation and independent t tests determined the level of association of therapist 0-to-10 ratings and 2-item screening with fear-avoidance and clinical measures. Therapist ratings of perceived patient fear-avoidance had fair to moderate interrater reliability (ICC2,1 = 0.663). Therapist ratings did not strongly correlate with FABQ or TSK-11 scores. Instead, they unexpectedly had stronger associations with ODQ and PCS scores. Both 2-item screening questions were associated with FABQ-physical activity scores, while the fear of physical activity question was also associated with FABQ-work, TSK-11, PCS, and ODQ scores

The purpose of this study was to explore the lived experiences of self-harm and harm to others from the perspective of two adult offspring and a father, the latter of whom was prone to alcohol abuse and domestic violence and had attempted suicide. Written informed consents were obtained from the subjects after a detailed explanation of the research aims and procedures. A qualitative, phenomenological method was applied for the study. Three subjects were interviewed using a semi-structured interview guide designed by the researchers and based on the aims of the study over a six-month period of home care. A qualitative content analysis based on a phenomenological method was used to identify themes in the data. Two main categories emerged: (1) the mutual harm to the couple subsystem, (2) the misplaced parental-child subsystem. Subsequently, two to four themes were identified from each category. These results provide a better analysis and understanding of the perceived experiences of the harm to the spouse, parental, and sibling subsystems. They should also help health professionals to improve awareness of the lived experiences associated with the issues of self-harm and threats of harm to others. This study could serve as a valuable reference in promoting possible prevention strategies aiming at the reduction of self-harm and harm to others in dysfunctional families within the community.

Ryckman, Richard M; Thornton, Bill; Gold, Joel A

2009-03-01

The lack of an adequate psychometric instrument has impeded personality theory testing in the area of competition avoidance. The authors conducted 6 studies in an attempt to remedy this deficiency by constructing an individual-difference measure of competition avoidance. In line with K. Horney's (1937) interpersonal theory of neurosis, participants who were higher in competition avoidance showed higher levels of neuroticism, greater fears of both success and failure, a lower desire to prove themselves in competitive situations, higher levels of self-handicapping, and more maladaptiveness than those participants who were lower in competition avoidance. Also, they were more modest and willing to conform to group standards than were those lower in competition avoidance. The authors discuss the measure's potential usefulness as a diagnostic and assessment tool in academic, athletic, and clinical settings.

Towards better patient care: drugs to avoid.

Science.gov (United States)

2013-04-01

Common sense dictates that one should choose tried and tested drugs with proven, concrete benefits that outweigh their adverse effects. Many new drugs are approved each year, often despite a lack of solid evidence that they are any better than existing treatments. Worse, some are approved despite being less effective or more harmful than current options. Massive promotion is used to ensure that such drugs achieve a positive image in the eyes of healthcare professionals and patients. Renowned "opinion leaders" intervene in their favour at conferences and in specialist media, and their opinions are further propagated by specialists in the field. Finally, campaigns in the lay media are used to highlight the target illness, encouraging patients to request a prescription. New data sometimes show that older, initially promising drugs are less effective or more harmful than first thought. For all these reasons, many drugs that are now present on the market are more harmful than beneficial and should be avoided. Unfortunately, negative assessment data and warnings are often drowned in the flood of promotion and advertising. Front-line healthcare professionals who are determined to act in their patients' best interests can find themselves swimming against a tide of specialist opinion, marketing authorisation, and reimbursement decisions. By leaving drugs that are more harmful than beneficial on the market and contenting themselves with simple half-measures, healthcare authorities are failing in their duty to protect patients. Prescrire, a journal funded solely by its subscribers, does not seek to do the work of health authorities, and does not have the means to do so. Prescrire's goal is simply to help healthcare professionals provide better care. The following text lists the principal drugs that we consider more harmful than beneficial, based on our reviews published between 2010 and 2012 in our French edition. These drugs should not be used.

A recent comprehensive review has been carried out to quantify the benefits and harms of the European population-based mammographic screening programs. Five literature reviews were conducted on the basis of the observational published studies evaluating breast cancer mortality reduction, breast cancer overdiagnosis, and false-positive results. On the basis of the studies reviewed, the authors present a first estimate of the benefit and harm balance sheet. For every 1,000 women screened biennially from ages 50 to 51 years until ages 68 to 69 years and followed up until age 79 years, an estimated seven to nine breast cancer deaths are avoided, four cases are overdiagnosed, 170 women have at least one recall followed by noninvasive assessment with a negative result, and 30 women have at least one recall followed by invasive procedures yielding a negative result. The chance of a breast cancer death being avoided by population-based mammography screening of appropriate quality is more than that of overdiagnosis by screening. These outcomes should be communicated to women offered service screening in Europe. ©2014 American Association for Cancer Research.

Data on suicides, attempted suicides and other self-harming behaviours that occurred in Italian prisons from 1990 to 2002 was studied on official records, as documented by the Ministry of Justice. Over the study interval, completed suicide rates in Italian prisons were constantly about ten times higher than among the general population, but over time they did not increase significantly despite nearly a doubling in the absolute number of inmates. The rate of completed suicides in overcrowded prisons was about ten times higher than in non-overcrowded ones. Attempted suicides were about ten times higher than completed suicides, with females being significantly more likely to attempt to take their own lives and males being more likely to complete suicide. Self-injuring acts without the intent to die involve about one in every ten individuals, with foreigners (non-EU citizens mostly) being twice as likely to self-harm than residents. A better identification of the people suffering from mental disorders and a reduction in prison overcrowding are two key issues that need to be implemented to reduce the impact of suicide and self-harming behaviours among convicts.

The aim of this study was to determine the personality characteristics of obese and morbidly obese individuals with no psychiatric disorder and the correlation between these characteristics and body image and self-esteem. Sixty-nine obese individuals and 69 healthy controls, matched in age, sex and marital status, were included in the study. Psychiatric disorders were excluded for all participants using SCID-I and II. Obese and healthy volunteers were compared in terms of body image, self-esteem and personality characteristics. TCI harm avoidance scores were higher in obese individuals compared to healthy controls. Harm avoidance scores were also higher in individuals with morbid obesity compared to non-morbid individuals, while self-directedness and persistence scores were lower. Body image dissatisfaction was higher in obese individuals. There was a negative correlation in obese individuals between body image and self-esteem scale scores and harm avoidance scores, and a positive correlation with self-directedness scores. An elevated harm avoidance temperament characteristic may be correlated with obesity. Furthermore, high harm avoidance, low self-directedness and low persistence may be significant personality characteristics in a process leading to morbid obesity. In addition, harm avoidance temperament and self-directedness personality characteristics may be correlated with body image dissatisfaction and self-esteem in obese individuals.

Presentation at an accident and emergency (A&E) department is a key opportunity to engage with a young person who self-harms. The needs of this vulnerable group and their fears about presenting to healthcare services, including A&E, are poorly understood. To examine young people's perceptions of A&E treatment following self-harm and their views on what constitutes a positive clinical encounter. Secondary analysis of qualitative data from an experimental online discussion forum. Threads selected for secondary analysis represent the views of 31 young people aged 16-25 with experience of self-harm. Participants reported avoiding A&E whenever possible, based on their own and others' previous poor experiences. When forced to seek emergency care, they did so with feelings of shame and unworthiness. These feelings were reinforced when they received what they perceived as punitive treatment from A&E staff, perpetuating a cycle of shame, avoidance and further self-harm. Positive encounters were those in which they received 'treatment as usual', i.e. non-discriminatory care, delivered with kindness, which had the potential to challenge negative self-evaluation and break the cycle. The clinical needs of young people who self-harm continue to demand urgent attention. Further hypothesis testing and trials of different models of care delivery for this vulnerable group are warranted. © The Royal College of Psychiatrists 2016.

Banking deregulation and corporate tax avoidance

Full Text Available We investigate whether tax avoidance substitutes for external financing. We exploit interstate banking deregulation as a quasi-external shock to examine whether firms engage in less tax avoidance after banking deregulation, because of cheaper and easier access to credit from banks. We find no empirical evidence to support this substitutive relation, even for firms with higher financial constraints or firms with higher external financing dependence.

In comparison to carbon dioxide, fluorinated greenhouse gases are more harmful up to a factor of 24,000. Today the amount of fluorinated greenhouse gases of the world-wide emissions of climatic harmful gases amounts 2 % and increases to 6 % in the year 2050. The authors of the contribution under consideration report on possibilities for the avoidance of the emissions of fluorinated greenhouse gases. The characteristics and ecological effects of fluorinated gases as well as the development of the emission in Germany are presented. Subsequently, the applications of fluorinated hydrocarbons are described.

The aim of the study was to examine how social care beneficiaries rate the relative harmfulness of tobacco/nicotine-containing products compared to traditional cigarettes. This information is crucial for the development of effective tobacco control strategies targeting disadvantaged populations. The cross-sectional study covered 1817 respondents who were taking advantage of social aid services offered by the local social care institutions in the Piotrkowski district, via face-to-face interviews. The linear regression analysis indicated that relative to women, men consider slim cigarettes, smokeless tobacco and e-cigarettes to be more harmful than traditional cigarettes ( p traditional cigarettes reported menthol cigarettes to be less harmful than traditional cigarettes, relative to the non-smokers ( p = 0.05). The current results demonstrate that social care beneficiaries are not aware of the fact that some products are less harmful than others. Education concerning tobacco/nicotine products should include advice on how to reduce the adverse health effects of smoking (e.g., avoiding inhalation of combusted products), while driving the awareness that no nicotine-containing products are safe.

Strategies for an effective tobacco harm reduction policy in Indonesia

Full Text Available Tobacco consumption is a major causative agent for various deadly diseases such as coronary artery disease and cancer. It is the largest avoidable health risk in the world, causing more problems than alcohol, drug use, high blood pressure, excess body weight or high cholesterol. As countries like Indonesia prepare to develop national policy guidelines for tobacco harm reduction, the scientific community can help by providing continuous ideas and a forum for sharing and distributing information, drafting guidelines, reviewing best practices, raising funds, and establishing partnerships. We propose several strategies for reducing tobacco consumption, including advertisement interference, cigarette pricing policy, adolescent smoking prevention policy, support for smoking cessation therapy, special informed consent for smokers, smoking prohibition in public spaces, career incentives, economic incentives, and advertisement incentives. We hope that these strategies would assist people to avoid starting smoking or in smoking cessation.

[Psychiatric treatment of deliberate self-harm in the out-of-hours services].

Science.gov (United States)

Walby, Fredrik A; Ness, Ewa

2009-04-30

Patients who harm themselves are often considered difficult to treat. There are no evidence-based approaches available for the emergency setting. General practitioners should nevertheless be able to offer interventions directed towards emotional needs in self-harm patients. In this article we suggest how to intervene in such situations. Based on experience from Oslo psychiatric out-of-hours service and with elements from Dialectic Behavioural Therapy, we present a five-step model for treatment of these patients in an out-of-hours service within the primary health care services. The aim of this model is to bring the patient out of the acute crisis and to arrange for further treatment. Assessment, validation or confirmation, problem-solving, avoiding unnecessary hospitalisation, and focus on continuing established treatment, are important elements in the proposed intervention. This can all be carried out in 60 - 90 min. The model may be suitable for training general practitioners to meet and care for patients with self-harm behaviour in the out-hours-services. We have positive experience with the intervention, but systematic research is necessary to assess the effect of the model.

Controversy persists about optimal mammography screening strategies. To evaluate screening outcomes, taking into account advances in mammography and treatment of breast cancer. Collaboration of 6 simulation models using national data on incidence, digital mammography performance, treatment effects, and other-cause mortality. United States. Average-risk U.S. female population and subgroups with varying risk, breast density, or comorbidity. Eight strategies differing by age at which screening starts (40, 45, or 50 years) and screening interval (annual, biennial, and hybrid [annual for women in their 40s and biennial thereafter]). All strategies assumed 100% adherence and stopped at age 74 years. Benefits (breast cancer-specific mortality reduction, breast cancer deaths averted, life-years, and quality-adjusted life-years); number of mammograms used; harms (false-positive results, benign biopsies, and overdiagnosis); and ratios of harms (or use) and benefits (efficiency) per 1000 screens. Biennial strategies were consistently the most efficient for average-risk women. Biennial screening from age 50 to 74 years avoided a median of 7 breast cancer deaths versus no screening; annual screening from age 40 to 74 years avoided an additional 3 deaths, but yielded 1988 more false-positive results and 11 more overdiagnoses per 1000 women screened. Annual screening from age 50 to 74 years was inefficient (similar benefits, but more harms than other strategies). For groups with a 2- to 4-fold increased risk, annual screening from age 40 years had similar harms and benefits as screening average-risk women biennially from 50 to 74 years. For groups with moderate or severe comorbidity, screening could stop at age 66 to 68 years. Other imaging technologies, polygenic risk, and nonadherence were not considered. Biennial screening for breast cancer is efficient for average-risk populations. Decisions about starting ages and intervals will depend on population characteristics and the

Background and purpose: We previously found considerable variation in information provision on preoperative radiotherapy (PRT) in rectal cancer. Our aims were to reach consensus among patients and oncologists on which benefits/harms of PRT should be addressed during the consultation, and to assess congruence with daily clinical practice. Materials and methods: A four-round Delphi-study was conducted with two expert panels: (1) 31 treated rectal cancer patients and (2) 35 radiation oncologists. Thirty-seven possible benefits/harms were shown. Participants indicated whether addressing the benefit/harm was (1) essential, (2) desired, (3) not necessary, or (4) to be avoided. Consensus was assumed when ⩾80% of the panel agreed. Results were compared to 81 audio-taped consultations. Results: The panels reached consensus that six topics should be addressed in all patients (local control, survival, long term altered defecation pattern and faecal incontinence, perineal wound healing problems, advice to avoid pregnancy), three in male patients (erectile dysfunction, ejaculation disorder, infertility), and four in female patients (vaginal dryness, pain during intercourse, menopause, infertility). On average, less than half of these topics were addressed in daily clinical practice. Conclusions: This study showed substantial overlap between benefits/harms that patients and oncologists consider important to address during the consultation, and at the same time poor congruence with daily clinical practice

The rise in Internet use adds a new dimension to suicide prevention. We investigated suicide/self-harm (S/Sh)-related Internet use among patients presenting to hospital with self-harm. We asked 1,198 adult and 315 child and adolescent patients presenting to hospital following self-harm in a city in South West England about Internet use associated with their hospital presentation. Associations between Internet use and sociodemographic and clinical characteristics were investigated using multivariable logistic regression models. Focus groups with clinicians explored the acceptability and utility of asking about Internet use. The prevalence of S/Sh-related Internet use was 8.4% (95% CI: 6.8-10.1%) among adult hospital presentations and 26.0% (95% CI = 21.3-31.2%) among children's hospital presentations. In both samples, S/Sh-related Internet use was associated with higher levels of suicidal intent. Mostly, clinicians found it acceptable to ask about Internet use during psychosocial assessments and believed this could inform perceptions of risk and decision-making. It is unclear whether the findings in this study are applicable to the general self-harm patient population because only those who had psychosocial assessments were included. S/Sh-related Internet use is likely to become increasingly relevant as the Internet-native generation matures. Furthermore, Internet use may be a proxy marker for intent.

Effects of IFRS adoption on tax avoidance

Directory of Open Access Journals (Sweden)

Renata Nogueira Braga

Full Text Available ABSTRACT This study investigates the association between mandatory International Financial Reporting Standards (IFRS adoption and corporate tax avoidance. In this study, tax avoidance is defined as a reduction in the effective corporate income tax rate through tax planning activities, whether these are legal, questionable, or even illegal. Three measures of tax avoidance are used and factors at the country and firm level (that have already been associated with tax avoidance in prior research are controlled. Using samples that range from 9,389 to 15,423 publicly-traded companies from 35 countries, covering 1999 to 2014, it is found that IFRS adoption is associated with higher levels of corporate tax avoidance, even when the level of book-tax conformity required in the countries and the volume of accruals are controlled, both of which are considered potential determinants of this relationship. Furthermore, the results suggest that after IFRS adoption, firms in higher book-tax conformity environments engage more in tax avoidance than firms in lower book-tax conformity environments. It is also identified that engagement in tax avoidance after IFRS adoption derives not only from accruals management, but also from practices that do not involve accruals. The main conclusion is that companies engage more in tax avoidance after mandatory IFRS adoption.

Social acceptance of technologies in relation to their benefit and harm

Sobajima, Makoto

2001-03-01

The progress and popularization of scientific techniques have brought large effects on peoples' life. In those effects, the realization of benefit (advantage) that scientific techniques for bringing abundance and convenience are aiming at and the appearance of unintentional harm spreading on the back coexist in many cases. So it can not be overlooked that the harm side is affecting people as large damages as technologies develop to higher level and more complicated. The common cause of them is thought to be lack of preliminary assessment and regulation before introducing those new technologies with the background of pursuit of mass production and mass consumption. In this research, many of examples of various effects are surveyed in literatures and analyzed to first contrast benefit and harm brought by scientific techniques. As for the harm, damage actually suffered and the possibility of hazard are classified from the view point of risks and methodologies of social risk management are discussed. In addition, externalities in environment as a kind of harm are evaluated. On this basis, policy requirements on social system for minimizing the harm brought by technologies and promoting people's acceptance of technologies in the future society are proposed as political attainment.

The Brazilian Network for Humane Education (RedEH( is an independent and self-managed group comprised of academics from ten different Brazilian states and a number of international collaborators. In 2016, in a concerted effort to change the educational field in Brazil and propagate humane education, RedEH sent a request to the Brazilian National Council for the Control of Animal Experimentation (CONCEA(, asking that harmful animal use in education in professional and undergraduate courses be banned. This was the first formal request for a total replacement of harmful animal use in education in Brazil, and represented a major historic landmark in the advancement of Brazilian science education. This paper presents the full text of the request, as well as outlining its national and international repercussions. The request was supported by InterNICHE and representatives of 18 other international organisations. A major national impact of the request was its recognition by the Federal Council of Veterinary Medicine. With this action, academics and researchers took a potentially revolutionary step in the Brazilian education arena, with regard to advancing and supporting a higher quality, ethical and democratic educational system.

The ultimate objective of this program is to provide an approach to understanding and communicating health-care harm and cost to compel health-care provider leadership teams to vote "yes" to investments in patient safety initiatives, with the confidence that clinical, financial, and operational performance will be improved by such programs. Through a coordinated combination of literature evaluations, careful mapping of high impact scenarios using simulated patients and consensus review of clinical, operational, and financial factors, we confirmed value in such approaches to decision support information for hospital leadership teams to invest in patient safety projects. The study resulted in the following preliminary findings: ·Communication between hospital quality and finance departments can be much improved by direct collaborative relationships through regular meetings to help both clarify direct costs, indirect costs, and the savings of waste and harm to patients by avoidance of infections. ·Governance leaders and the professional administrative leaders should consider establishing the structures and systems necessary to act on risks and hazards as they evolve to deploy resources to areas of harm and risk. ·Quality and Infection Control Professionals can best wage their war on healthcare waste and harm by keeping abreast of the latest literature regarding the latest measures, standards, and safe practices for healthcare-acquired infections and hospital-acquired conditions. ·Regular reviews of patients with health-careYassociated infections, with direct attention to the attributable cost of treatment and how financial waste and harm to patients may be avoided, may provide hospital leaders with new insights for improvement. ·If hospitals developed their own risk scenarios to determine impact of harm and waste from hospital-acquired conditions in addition to impact scenarios for specific processes through technology and process innovations, they would have

The purpose of this study was to ascertain the prevalence and correlates of self-harm among young people in detention in Australia. The sample included 215 (177 male; 38 female) young people who were in youth detention in the state of Victoria, Australia. Participants were administered a series of questionnaires related to self-harm, mental health, socio-environmental experiences and behaviours. Overall, one-third (33%) of the sample reported previous self-harm and 12% reported at least one suicide attempt. In a multivariate logistic regression analysis, a history of childhood trauma, contact with mental health services, and low educational interest significantly increased the likelihood of self-harm. Young people who reported a suicide attempt scored significantly higher on the measure of childhood trauma than did youth who had engaged in non-suicidal self-harm. Findings demonstrate a strong connection between childhood traumatic experiences and suicidal behaviours for youth in detention. Trauma histories and mental health concerns must be considered when identifying youth at increased risk of self-harm. PMID:29447289

Sex-work harm reduction.

Rekart, Michael L

Sex work is an extremely dangerous profession. The use of harm-reduction principles can help to safeguard sex workers' lives in the same way that drug users have benefited from drug-use harm reduction. Sex workers are exposed to serious harms: drug use, disease, violence, discrimination, debt, criminalisation, and exploitation (child prostitution, trafficking for sex work, and exploitation of migrants). Successful and promising harm-reduction strategies are available: education, empowerment, prevention, care, occupational health and safety, decriminalisation of sex workers, and human-rights-based approaches. Successful interventions include peer education, training in condom-negotiating skills, safety tips for street-based sex workers, male and female condoms, the prevention-care synergy, occupational health and safety guidelines for brothels, self-help organisations, and community-based child protection networks. Straightforward and achievable steps are available to improve the day-to-day lives of sex workers while they continue to work. Conceptualising and debating sex-work harm reduction as a new paradigm can hasten this process.

While recent studies have found problem-solving impairments in individuals who engage in deliberate self-harm (DSH), few studies have examined repeaters and non-repeaters separately. The aim of the present study was to investigate whether specific types of problem-solving are associated with repeated DSH. As part of the WHO/EURO Multicentre Study on Suicidal Behaviour, 836 medically treated DSH patients (59% repeaters) from 12 European regions were interviewed using the European Parasuicide Study Interview Schedule (EPSIS II) approximately 1 year after their index episode. The Utrecht Coping List (UCL) assessed habitual responses to problems. Factor analysis identified five dimensions--Active Handling, Passive-Avoidance, Problem Sharing, Palliative Reactions and Negative Expression. Passive-Avoidance--characterized by a pre-occupation with problems, feeling unable to do anything, worrying about the past and taking a gloomy view of the situation, a greater likelihood of giving in so as to avoid difficult situations, the tendency to resign oneself to the situation, and to try to avoid problems--was the problem-solving dimension most strongly associated with repetition, although this association was attenuated by self-esteem. The outcomes of the study indicate that treatments for DSH patients with repeated episodes should include problem-solving interventions. The observed passivity and avoidance of problems (coupled with low self-esteem) associated with repetition suggests that intensive therapeutic input and follow-up are required for those with repeated DSH.

Self-harm (intentional self-poisoning and self-injury) in children and adolescents is often repeated and is associated with increased risk of future suicide. We have investigated factors associated with these outcomes. We used data collected in the Multicentre Study of Self-harm in England on all self-harm hospital presentations by individuals aged 10-18 years between 2000 and 2007, and national death information on these individuals to the end of 2010. Cox hazard proportional models were used to identify independent and multivariable predictors of repetition of self-harm and of suicide. Repetition of self-harm occurred in 27.3% of individuals (N = 3920) who presented between 2000 and 2005 and were followed up until 2007. Multivariate analysis showed that repetition was associated with age, self-cutting, and previous self-harm and psychiatric treatment. Of 51 deaths in individuals who presented between 2000 and 2007 and were followed up to 2010 (N = 5133) half (49.0%) were suicides. The method used was usually different to that used for self-harm. Multivariate analysis showed that suicide was associated with male gender [Hazard ratio (HR) = 2.4, 95% CI 1.2-4.8], self-cutting (HR = 2.1, 95% CI 1.1-3.7) and prior psychiatric treatment at initial presentation (HR = 4.2, 95% CI 1.7-10.5). It was also associated with self-cutting and history of psychiatric treatment at the last episode before death, and history of previous self harm. Self-cutting as a method of self-harm in children and adolescents conveys greater risk of suicide (and repetition) than self-poisoning although different methods are usually used for suicide. The findings underline the need for psychosocial assessment in all cases. © 2012 The Authors. Journal of Child Psychology and Psychiatry © 2012 Association for Child and Adolescent Mental Health.

Long-term behavioral changes related to learning and experience have been shown to be associated with structural remodeling in the brain. Leaf-cutting ants learn to avoid previously preferred plants after they have proved harmful for their symbiotic fungus, a process that involves long-term olfactory memory. We studied the dynamics of brain microarchitectural changes after long-term olfactory memory formation following avoidance learning in Acromyrmex ambiguus. After performing experiments to...

The relationship between alcohol consumption and related harm among young university students.

Science.gov (United States)

Hart, Ellen; Burns, Sharyn

2016-04-01

Issue addressed Research has shown that Australian university students consume alcohol at a higher level than their peers from the general population and are therefore more likely to witness and experience alcohol-related harm. This study measured the prevalence of alcohol consumption among 18-24-year-old university students and the association between alcohol consumption and witnessed and experienced harms. Methods A random cross-sectional sample of university students aged 18-24 years (n=2466) was recruited via the University Survey Office and through random intercept at campus market day. All participants completed an online survey that included the Alcohol Use Disorders Identification Test, Alcohol Problems Scale and an additional scale measuring witnessed harm. Results Principal Components Analysis revealed three factors within the Alcohol Problems Scale; i.e. Criminal and Aggressive Behaviour, Health and Emotional Harms and Sexual Harms. Students who consume alcohol at high-risk levels were significantly more likely to score highly on each factor, 1.6 times more likely to experience harm and 1.1 times more likely to witness harm than students who consume alcohol at low-risk levels. Conclusions The positive association between alcohol consumption and alcohol-related harm supports previous findings. This study adds previous research through the categorisation of harm into factors. So what? Integrated and comprehensive interventions addressing alcohol consumption among young university students that are informed by evidence-based research can be tailored to ensure that they meet the needs of the target group.

Measuring emergency department nurses' attitudes towards deliberate self-harm using the Self-Harm Antipathy Scale.

The emergency department is an important gateway for the treatment of self-harm patients. Nurses\\' attitudes towards patients who self-harm can be negative and often nurses experience frustration, helplessness, ambivalence and antipathy. Patients are often dissatisfied with the care provided, and meeting with positive or negative attitudes greatly influences whether they seek additional help. A quantitative design was utilised to measure emergency department nurses\\' attitudes towards deliberate self-harm. The \\'Self-Harm Antipathy Scale\\

Social acceptance of technologies in relation to their benefit and harm

Energy Technology Data Exchange (ETDEWEB)

The progress and popularization of scientific techniques have brought large effects on peoples' life. In those effects, the realization of benefit (advantage) that scientific techniques for bringing abundance and convenience are aiming at and the appearance of unintentional harm spreading on the back coexist in many cases. So it can not be overlooked that the harm side is affecting people as large damages as technologies develop to higher level and more complicated. The common cause of them is thought to be lack of preliminary assessment and regulation before introducing those new technologies with the background of pursuit of mass production and mass consumption. In this research, many of examples of various effects are surveyed in literatures and analyzed to first contrast benefit and harm brought by scientific techniques. As for the harm, damage actually suffered and the possibility of hazard are classified from the view point of risks and methodologies of social risk management are discussed. In addition, externalities in environment as a kind of harm are evaluated. On this basis, policy requirements on social system for minimizing the harm brought by technologies and promoting people's acceptance of technologies in the future society are proposed as political attainment.

Harm and the Boundaries of Disease.

Science.gov (United States)

McGivern, Patrick; Sorial, Sarah

2017-08-01

What is the relationship between harm and disease? Discussions of the relationship between harm and disease typically suffer from two shortcomings. First, they offer relatively little analysis of the concept of harm itself, focusing instead on examples of clear cases of harm such as death and dismemberment. This makes it difficult to evaluate such accounts in borderline cases, where the putative harms are less severe. Second, they assume that harm-based accounts of disease must be understood normatively rather than naturalistically, in the sense that they are inherently value based. This makes such accounts vulnerable to more general objections of normative accounts of disease. Here we draw on an influential account of harm from the philosophy of law to develop a harm-based account of disease that overcomes both of these shortcomings. © The Author 2017.

Harm reduction principles for healthcare settings

Mary Hawk

2017-10-01

Full Text Available Abstract Background Harm reduction refers to interventions aimed at reducing the negative effects of health behaviors without necessarily extinguishing the problematic health behaviors completely. The vast majority of the harm reduction literature focuses on the harms of drug use and on specific harm reduction strategies, such as syringe exchange, rather than on the harm reduction philosophy as a whole. Given that a harm reduction approach can address other risk behaviors that often occur alongside drug use and that harm reduction principles have been applied to harms such as sex work, eating disorders, and tobacco use, a natural evolution of the harm reduction philosophy is to extend it to other health risk behaviors and to a broader healthcare audience. Methods Building on the extant literature, we used data from in-depth qualitative interviews with 23 patients and 17 staff members from an HIV clinic in the USA to describe harm reduction principles for use in healthcare settings. Results We defined six principles of harm reduction and generalized them for use in healthcare settings with patients beyond those who use illicit substances. The principles include humanism, pragmatism, individualism, autonomy, incrementalism, and accountability without termination. For each of these principles, we present a definition, a description of how healthcare providers can deliver interventions informed by the principle, and examples of how each principle may be applied in the healthcare setting. Conclusion This paper is one of the firsts to provide a comprehensive set of principles for universal harm reduction as a conceptual approach for healthcare provision. Applying harm reduction principles in healthcare settings may improve clinical care outcomes given that the quality of the provider-patient relationship is known to impact health outcomes and treatment adherence.

Zhang, Jixiang; Song, Jianwei; Wang, Jing

2016-12-01

This study aims to define the characteristics of adolescents who have engaged in self-harm behavior and ascertain the risk factors. From January 2013 to January 2014, 4,176 adolescents from senior middle schools in Linyi, China, were administered four questionnaire surveys to ascertain the following: incidence of self-harm behavior regarding the frequency of different self-harm behaviors by group (never/one to five times/greater than five times in the last 6 months) and then comparing the self-harm behavior of the different subgroups; symptom self-check, comparing the differences between the adolescents with self-harm behavior and without in nine subscales (somatization, obsessive-compulsive symptoms, interpersonal sensitivity, depression, anxiety, hostility, fear, paranoid, and psychosis); Adolescent Self-Rating Life Events Check List scores; and Egna Minnenav Barndoms Uppfostran (EMBU) scores. Multivariate logistic regression analysis was used to determine the risk factors of self-harm in adolescents. The incidence of adolescent self-harm was 27.60%; the occurrence of adolescent self-harm was closely related to their mental health status, stressful life events, and EMBU. Being female, an urban student, or an only child; having poor school performance or experiences of stressful life events, harsh parenting styles, or excessive interference; and poor mental health were the risk factors for adolescent self-harm. The incidence of adolescent self-harm was high, and their mental health status, stressful life events, and EMBU affected the occurrence of adolescent self-harm, which is an issue that needs greater attention. © 2016 John Wiley & Sons Australia, Ltd.

Science under pressure: problematic behaviours and social harms

Full Text Available This paper will suggest the use of the Social Harm Approach (Hillyard, Pantazis, Tobs & Gordon, 2004 to problematic behaviours occurring in scientific research and higher education teaching. By analyzing data collected through interviews to scholars, it is possible to state that fabrication, falsification and plagiarism are the most criticized deviant behaviours in science. It is less common for actors to consider other problematic behaviours arising from the pressure (to publish, to get grants felt by them and originated at the heart of the organizations devoted to science. Or problematic behaviours created on the intersection of universities, corporations and/or the state (ex. commissioned research. Also, those interviewed did not have a coherent view on the rules governing science and higher education. Thus, considering the scattering of (individual and organizational problematic behaviours and rules governing them, a new approach will be put forward, one by which processes of scientific production and dissemination must be considered according to the social harms (financial, economic, physical they may cause.

Digital Self-Harm Among Adolescents.

Patchin, Justin W; Hinduja, Sameer

2017-12-01

Despite increased media and scholarly attention to digital forms of aggression directed toward adolescents by their peers (e.g., cyberbullying), very little research has explored digital aggression directed toward oneself. "Digital self-harm" is the anonymous online posting, sending, or otherwise sharing of hurtful content about oneself. The current study examined the extent of digital self-harm among adolescents. Survey data were obtained in 2016 from a nationally representative sample of 5,593 American middle and high school students (12-17 years old). Logistic regression analysis was used to identify correlates of participation in digital self-harm. Qualitative responses were also reviewed to better understand motivations for digital self-harm. About 6% of students have anonymously posted something online about themselves that was mean. Males were significantly more likely to report participation (7.1% compared to 5.3%). Several statistically significant correlates of involvement in digital self-harm were identified, including sexual orientation, experience with school bullying and cyberbullying, drug use, participation in various forms of adolescent deviance, and depressive symptoms. Digital self-harm is a new problem that demands additional scholarly attention. A deeper inquiry as to the motivations behind this behavior, and how it correlates to offline self-harm and suicidal ideation, can help direct mental health professionals toward informed prevention approaches.

Deprivation as un-experienced harm?

DEFF Research Database (Denmark)

Keerus, Külli; Gjerris, Mickey; Röcklinsberg, Helena

2017-01-01

Tom Regan encapsulated his principle of harm as a prima facie direct duty not to harm experiencing subjects of a life. However, his consideration of harm as deprivation, one example of which is loss of freedom, can easily be interpreted as a harm, which may not be experienced by its subject....... This creates a gap between Regan’s criterion for moral status and his account of what our duties are. However, in comparison with three basic paradigms of welfare known in nonhuman animal welfare science, Regan’s understanding coheres with a modified version of a feelings-based paradigm: not only the immediate...... feelings of satisfaction, but also future opportunities to have such feelings, must be taken into account. Such an interpretation is compatible with Regan’s understanding of harm as deprivation. The potential source of confusion, however, lies in Regan’s own possible argumentative mistakes....

A past history of self-harm is a significant risk factor for suicide in older people. The aims of this study are to (i) characterize older people who present with self-harm to emergency departments (EDs); and (ii) determine the predictors for repeat self-harm and suicide. Demographic and clinical data were retrospectively collected on older people (age 65+ years), who presented to seven EDs in New Zealand following an episode of self-harm between 1st July 2010 and 30th June 2013. In addition, 12-month follow-up information on repeat self-harm and suicide was collected. The sample included 339 older people (55.2% female) with an age range of 65-96 years (mean age = 75.0; SD = 7.6). Overdose (68.7%) was the most common method of self-harm. 76.4% of the self-harm cases were classified as suicide attempts. Perceived physical illness (47.8%) and family discord (34.5%) were the most common stressors. 12.7% of older people repeated self-harm and 2.1% died by suicide within 12 months. Older people who had a positive blood alcohol reading (OR = 3.87, 95% Cl = 1.35-11.12, p = 0.012) and were already with mental health services at the index self-harm (OR = 2.73, 95% Cl = 1.20-6.25, p = 0.047) were more likely to repeat self-harm/suicide within 12 months. Older people who self-harm are at very high risk of repeat self-harm and suicide. Screening and assessment for alcohol use disorders should be routinely performed following a self-harm presentation, along with providing structured psychological treatment as an adjunct to pharmacological treatment for depression and interventions to improve the person's resilience resources.

In order to avoid a pollution of the near surface ground water during the post closure phase of the Konrad repository the acceptable amount of material harmful to water in the radioactive waste is restricted. For this purpose the KONRAD plan approval order includes waste requirements referring to the German water law ('water law permission'). In a first part of this contribution the water law permission for the KONRAD repository is introduced. This permission contains a list of materials harmful to water with the respective limitations in mass and many instructions and proposals regarding the registering and balancing of these materials as well as quality assurance aspects. The second part deals with the implementation of the water law permission in the waste acceptance criteria. The waste producer has to describe his waste in a standardized way with respect to the material composition. The operator of the repository has to check this description and to register and balance the materials and substances harmful to water. This procedure is based on a standardized list of materials and a list of containers. In the third part quality control measures used for the proof of the compliance with the acceptance criteria (with respect to the water law permission) are described. In particular objective of the quality control, possible quality control options and acceptable margins are dealt with. (authors)

Receptivity to e-cigarette marketing, harm perceptions, and e-cigarette use.

2015-01-01

To test whether exposure and receptivity to e-cigarette marketing are associated with recent e-cigarette use among young adults through increased beliefs that e-cigarettes are less harmful than cigarettes. Data were collected from 307 multiethnic 4- and 2-year college students; approximately equal proportions of current, never, and former cigarette smokers [mean age = 23.5 (SD = 5.5); 65% female]. Higher receptivity to e-cigarette marketing was associated with perceptions that e-cigarettes are less harmful than cigarettes, which in turn, were associated with higher recent e-cigarette use. The findings provide preliminary support to the proposition that marketing of e-cigarettes as safer alternatives to cigarettes or cessation aids is associated with increased e-cigarette use among young adults. The findings have implications for development of e-cigarette regulations.

Do Coping Strategies Mediate the Relationship Between Parental Attachment and Self-Harm in Young People?

Science.gov (United States)

Glazebrook, Katie; Townsend, Ellen; Sayal, Kapil

2016-01-01

Insecure attachment is associated with self-harm in young people, but little research has explored the pathways through which this relationship develops. We investigated whether attachment impacts on self-harm via its effect on coping strategies and appraisal of problem-solving abilities. A total of 314 students aged 18-20 years completed an online survey with measures of parental attachment, emotion-focused and problem-focused coping strategies, and psychological distress and self-harm. A mediational model was not supported as there were no direct effects between parental attachment and self-harm. However, analysis of specific indirect pathways revealed that perceived parental attachment impacts on self-harm through problem-focused coping. Higher quality of attachment was associated with greater reliance on problem-focused (adaptive) coping, which in turn was associated with a decreased risk of having self-harmed. Furthermore, poorer paternal attachment was associated with lower appraisal of problem-solving skills, which in turn was associated with an increased risk of having self-harmed. Individuals with insecure attachment may be more vulnerable to self-harm because they lack other more constructive coping strategies for relieving stress.

2018-01-01

In this paper I examine the relationship between benefits, harms and evidence-based medicine in the context of British primary healthcare. First, I will examine: 'What is a benefit and what is a harm?' Second, what should we know about where the balance of risk and benefit appear to lie? Third, what should we do with this knowledge, particularly in the context of the biopsychosocial gaze of primary care? I conclude that even perfect knowledge about benefits and harms requires to be translated in the context of the individual patient: it also requires to be interpreted according to what that persons' wishes are. By reiterating again and again how biases are stacked in favour of recommending treatments and interventions well beyond their rational evidence, my hope is that more honest medicine will result in less but higher value medicine. Stopping doing things that don't work, or work rarely, or come with an unacceptable burden of side effects or appointments should make room for the pleasure of practicing medicine. •Even perfect knowledge about benefits and harms requires to be translated in the context of the individual patient: it also requires to be interpreted according to what that persons' wishes are.•In the real, messy frontline world of general practice, we will always have uncertainty about where the balance of risk and benefit might lie.

Harm reduction-the cannabis paradox

Directory of Open Access Journals (Sweden)

Melamede Robert

2005-09-01

Full Text Available Abstract This article examines harm reduction from a novel perspective. Its central thesis is that harm reduction is not only a social concept, but also a biological one. More specifically, evolution does not make moral distinctions in the selection process, but utilizes a cannabis-based approach to harm reduction in order to promote survival of the fittest. Evidence will be provided from peer-reviewed scientific literature that supports the hypothesis that humans, and all animals, make and use internally produced cannabis-like products (endocannabinoids as part of the evolutionary harm reduction program. More specifically, endocannabinoids homeostatically regulate all body systems (cardiovascular, digestive, endocrine, excretory, immune, nervous, musculo-skeletal, reproductive. Therefore, the health of each individual is dependant on this system working appropriately.

Relational stressors as predictors for repeat aggressive and self-harming incidents in child and adolescent psychiatric inpatient settings.

Science.gov (United States)

Ulke, Christine; Klein, Annette M; von Klitzing, Kai

2014-01-01

This study examined whether relational stressors such as psychosocial stressors, the therapist's absence and a change of therapist are associated with repeat aggressive or self-harming incidents in child and adolescent psychiatric inpatient care. The study data were derived from critical incident reports and chart reviews of 107 inpatients. In multinomial regression analysis, patients with repeat aggressive or self-harming incidents were compared with patients with single incidents. Results suggested that a higher number of psychosocial stressors and a change of therapist, but not the therapist's absence are predictors for repeat aggressive and self-harming incidents. There was a high prevalence of therapist's absence during both, single and repeat, incidents. Repeat aggressive incidents were common in male children and adolescents with disruptive behavior disorders. Repeat self-harming incidents were common in adolescent females with trauma-related disorders. Patients with repeat aggressive or self-harming incidents had a higher number of abnormal intrafamilial relationships and acute life events than patients with single incidents. Interventions to reduce a change of therapist should in particular target children and adolescents with a higher number of psychosocial stressors and/or a known history of traumatic relational experiences. After a first incident, patients should have a psychosocial assessment to evaluate whether additional relational support is needed.

Rape avoidance behavior among Slovak women.

Science.gov (United States)

Prokop, Pavol

2013-05-28

Rape has been a recurrent adaptive problem for many species, including humans. Rape is costly to women in terms of disease transmission, partner abandonment, and unwanted pregnancy (among other costs). Therefore, behavioral strategies which allow women to avoid coercive men may have been favored by selection. In line with this evolutionary reasoning, the current research documented that physically stronger women and those in a committed romantic relationship reported more rape avoidance behavior. In addition, virgin women tended to perform more rape avoidance behavior compared with their non-virgin counterparts. Women with high conception risk perceived themselves as physically stronger, which may protect them against a potential rapist. Fear of unwanted pregnancy from rape decreased as age increased, reflecting higher fertility among younger participants. However, older women reported more rape avoidance behavior, which contradicts evolutionary predictions. The results provide some support for evolutionary hypotheses of rape avoidance behavior which suggest that woman's perception of rape is influenced by parental investment and perceived physical condition.

Contested space in the pharmacy: public attitudes to pharmacy harm reduction services in the West of Scotland.

Internationally, community pharmacies have become increasingly involved in providing harm reduction services and health advice to people who use illicit drugs. This paper considers public opinion of community pharmacy services. It discusses attitudes to harm reduction services in the context of stigmatization of addiction and people who use drugs. This exploratory study involved twenty-six purposively sampled members of the public, from the West of Scotland, participating in one of 5 focus groups. The groups were composed to represent known groups of users and non-users of community pharmacy, none of whom were problem drug users. Three thematic categories were identified: methadone service users in community pharmacies; attitudes to harm reduction policies; contested space. Harm reduction service expansion has resulted in a high volume of drug users in and around some Scottish pharmacies. Even if harm reduction services are provided discretely users' behavior can differentiate them from other pharmacy users. Drug users' behavior in this setting is commonly perceived to be unacceptable and can deter other consumers from using pharmacy services. The results of this study infer that negative public opinion is highly suggestive of stereotyping and stigmatization of people who use drugs. Participants considered that (1) community pharmacies were unsuitable environments for harm reduction service provision, as they are used by older people and those with children; (2) current drug policy is perceived as ineffective, as abstinence is seldom achieved and methadone was reported to be re-sold; (3) people who use drugs were avoided where possible in community pharmacies. Community pharmacy harm reduction services increasingly bring together the public and drug users. Study participants were reluctant to share pharmacy facilities with drug users. This paper concludes by suggesting mechanisms to minimize stigmatization. Copyright © 2014 Elsevier Inc. All rights reserved.

Harmful effects of ultraviolet radiation

Tanning for cosmetic purposes by sunbathing or by using artificial tanning devices is widespread. The hazards associated with exposure to ultraviolet radiation are of concern to the medical profession. Depending on the amount and form of the radiation, as well as on the skin type of the individual exposed, ultraviolet radiation causes erythema, sunburn, photodamage (photoaging), photocarcinogenesis, damage to the eyes, alteration of the immune system of the skin, and chemical hypersensitivity. Skin cancers most commonly produced by ultraviolet radiation are basal and squamous cell carcinomas. There also is much circumstantial evidence that the increase in the incidence of cutaneous malignant melanoma during the past half century is related to increased sun exposure, but this has not been proved. Effective and cosmetically acceptable sunscreen preparations have been developed that can do much to prevent or reduce most harmful effects to ultraviolet radiation if they are applied properly and consistently. Other safety measures include (1) minimizing exposure to ultraviolet radiation, (2) being aware of reflective surfaces while in the sun, (3) wearing protective clothing, (4) avoiding use of artificial tanning devices, and (5) protecting infants and children

Objective To test whether exposure and receptivity to e-cigarette marketing are associated with recent e-cigarette use among young adults through increased beliefs that e-cigarettes are less harmful than cigarettes. Methods Data were collected from 307 multiethnic 4- and 2-year college students; approximately equal proportions of current, never, and former cigarette smokers [mean age = 23.5 (SD = 5.5); 65% female]. Results Higher receptivity to e-cigarette marketing was associated with perceptions that e-cigarettes are less harmful than cigarettes, which in turn, were associated with higher recent e-cigarette use. Conclusions The findings provide preliminary support to the proposition that marketing of e-cigarettes as safer alternatives to cigarettes or cessation aids is associated with increased e-cigarette use among young adults. The findings have implications for development of e-cigarette regulations. PMID:25290604

Risk factors and correlates of deliberate self-harm behavior: a systematic review.

Deliberate self-harm behavior--without suicidal intent--is a serious health problem and may be studied as a clinical phenomenon in its own right. Empirical studies of sociodemographic and psychological correlates and risk factors are systematically reviewed. We searched Medline, PsycINFO, PSYNDEX (German psychological literature), and reference lists. We targeted self-induced bodily harm without conscious suicidal intent. Studies on suicidal behavior or self-poisoning were only included if they also assessed nonsuicidal self-harm. Fifty-nine original studies met the criteria. Deliberate self-harm may occur at all ages, yet adolescents and young adults are at a higher risk. Evidence on gender is complex. Only 5 studies realize a prospective design (6 months to 10 years) and test predictors. The majority use cross-sectional and retrospective methods. No longitudinal study (separately) examines new incidence. Evidence of correlates encompasses distal/proximal, person/environment, and state/trait factors. Many studies report associations between current self-harm behavior and a history of childhood sexual abuse. Adolescent and adult self-harmers experience more frequent and more negative emotions, such as anxiety, depression, and aggressiveness, than persons who do not self-harm. Two studies yield specific interactions between childhood trauma and current traits and states such as low emotional expressivity, low self-esteem, and dissociation with respect to a vulnerability to self-harm. Evidence of distal, biographical stressors is fairly strong. Proximal stressors have rarely been investigated; protective factors, hardly at all. Despite many findings of correlates, the data do not yet justify terming them risk factors. Longitudinal studies are needed.

Prior research suggests more than 70% of undergraduates have experienced harm from other students' drinking. This study built on the literature by, first, investigating whether secondhand harm cluster into latent factors that reflect distinct but related types of harm. Second, given the paucity of research examining factors that increase students' vulnerability to secondhand harm, we examined dimensions from Castellanos-Ryan and Conrod's 4-factor personality model for alcohol disorders (impulsivity [IMP], sensation seeking [SS], hopelessness [HOP], anxiety sensitivity [AS]) as predictors of secondhand harm exposure. We also investigated the possible mediating role of students' own problematic alcohol use in explaining personality-secondhand harm relationships. An online survey was administered to 1,537 first-year Canadian undergraduates (68% women). Problematic alcohol use was measured by the Alcohol Use Disorders Identification Test, and personality was measured by the Substance Use Risk Profile Scale. Eleven secondhand harm items were included. The secondhand harm clustered into 3 distinct but related factors: "strains" (e.g., interruption of sleep or study), "threats" (e.g., harassment or assault), and "interpersonal harm" (e.g., arguments with peers). Sixty-eight percent of respondents reported strains, 44% threats, and 64% interpersonal harm, and 35% reported experiencing all 3 types of harm, in the last term. All 4 personality dimensions were independently associated with greater secondhand harm exposure. HOP was directly associated with threats and interpersonal harm, and AS was directly associated with all 3 types of harm. SS and IMP were both indirectly associated with all 3 types of harm through students' own problematic alcohol use. In addition, IMP was directly related to threats. The prevalence of secondhand harm from alcohol is high among undergraduates. Findings suggest that distinct personality risks may predispose students to experience secondhand

Harm mediates the disgust-immorality link.

Many acts are disgusting, but only some of these acts are immoral. Dyadic morality predicts that disgusting acts should be judged as immoral to the extent that they seem harmful. Consistent with this prediction, 3 studies reveal that perceived harm mediates the link between feelings of disgust and moral condemnation-even for ostensibly harmless "purity" violations. In many cases, accounting for perceived harm completely eliminates the link between disgust and moral condemnation. Analyses also reveal the predictive power of anger and typicality/weirdness in moral judgments of disgusting acts. The mediation of disgust by harm holds across diverse acts including gay marriage, sex acts, and religious blasphemy. Revealing the endogenous presence and moral relevance of harm within disgusting-but-ostensibly harmless acts argues against modular accounts of moral cognition such as moral foundations theory. Instead, these data support pluralistic conceptions of harm and constructionist accounts of morality and emotion. Implications for moral cognition and the concept of "purity" are discussed.

2017-05-01

Harm reduction has had positive outcomes for people using sexual health and substance misuse services. Clinical guidance recommends these approaches may be appropriately adopted by mental health practitioners when managing some people who self-harm. There has, however, been very little research in this area. We explored practitioners' views of harm reduction as a strategy for supporting people who self-harm. The Self Harm Antipathy Scale (SHAS) was administered to a random sample of 395 mental health practitioners working on 31 wards in England, semi-structured interviews were then conducted with 18 survey respondents. Practitioners who had implemented the approach reported positive outcomes including a reduction in incidence and severity of self-harm and a perceived increase in empowerment of service users. Practitioners with no experience of using harm reduction were concerned that self-harm would increase in severity, and were unsure how to assess and manage risk in people under a harm reduction care plan. Some fundamentally disagreed with the principle of harm reduction for self-harm because it challenged their core beliefs about the morality of self-harm, or the ethical and potential legal ramifications of allowing individuals to harm themselves. This study was conducted solely with practitioners working on inpatient units. The majority of staff interviewed had no experience of harm reduction and so their concerns may not reflect challenges encountered by practitioners in clinical practice. Harm reduction is being used to support people who self-harm within inpatient psychiatry and some practitioners report potential benefits of this approach. However, this raises particularly complex practical, ethical and legal issues and further research is needed to assess the safety, acceptability and efficacy of the approach. Crown Copyright © 2017.

2017-01-01

There is a paucity of research on the prevalence and consequences of secondhand harms from alcohol. The current study (a) investigated whether secondhand harms can be clustered into latent factors that reflect distinct but related types of harms and (b) examined the associations between experiencing secondhand harms and mental health outcomes, including anxiety, depression, and subjective mental well-being, among first-year Canadian postsecondary students. The moderating effect of living arrangement (i.e., living on campus or not) on the associations was also tested. The sample included 1,885 first-year undergraduate students (49.8% female; mean age = 18.31 years) from three Canadian universities. Exploratory and confirmatory factor analyses were used to determine the factor structure of the harms measure. Path analysis was used to assess the association between harms and mental health outcomes. Models accounted for age, sex, and frequency of heavy drinking. Seventy-one percent of the sample reported experiencing at least one type of secondhand harm. The harms examined clustered into two distinct but related factors: strains (e.g., interrupted sleep) and threats (e.g., being harassed or insulted). Both threats and strains were associated with higher levels of anxiety and depression and poorer subjective well-being. Associations were stronger for threats and did not differ by living arrangement. Experiencing secondhand harms from alcohol, particularly threats, may have negative implications for student mental health over and above students' own drinking. Programs and policies on university campuses targeting both alcohol use and mental health should consider how to reduce both the prevalence and impact of secondhand harms from alcohol on students.

This review will focus on the rates, clinical characteristics, risk factors and methods of self-harm and suicide in different ethnic groups in the United Kingdom, providing an update synthesis of recent literature. Studies that met the inclusion criteria between 2003 and 2013 were reviewed using the following databases: MEDLINE, PsycINFO, EMBASE and CINAHL. The methodological quality of each study was then assessed using a structured scoring system. A total of 2,362 articles were retrieved, 10 of which matched the inclusion criteria were reviewed. Significant differences were found in the rates of self-harm between ethnic groups with Asian males being least likely to self-harm and Black females being most likely to self-harm. Also, Black and South Asian people were less likely to repeat self-harm. Factors that may help protect or predispose individuals to self-harm or attempt suicide (such as religion, mental health and coping styles) also differ between ethnic groups. There are clear ethnic differences in self-harm and suicide, which may be affected by factors such as cultural pressures and prevalence of mental illness. An awareness of these differences is vital to help prevent further attempts of self-harm and suicide. Further research into differences between ethnic and cultural groups and self-harm continues to be important. © The Author(s) 2015.

Public Involvement in Decisions to Avoid Costly Consequences Later

There should be an agreement of goals in any project that could produce harm. Why are we developing this technology? Who benefits and who pays? What would a 'cleanup' entail? There must be consideration of alternatives with a focus on reducing harm rather than just meeting allowable limits or promising that they will be met in the future. When alternatives are weighed, the burden should be on the proponent of the activity to provide truthful information to the public and provide access and resources necessary for participation. There must be a formal, legal obligation or duty to consider science as well as non-scientific information. It should not be up to those harmed to prove the damage and force the responsible parties to make retribution. It should be the burden of the proponents to measure potential risks, and prove that the benefits to everyone outweigh the risks to everyone. The role of government in decision making should also be redefined. The considerations now seem to be limited to whether or not an action is 'legal' or if it is 'safe'. There should also be a determination that it is 'necessary'. That may seem to be a very difficult question but put simply, if there are alternatives then a thing is not 'necessary'. Governmental decision makers would say: 'We acknowledge that our world will never be free from risk. However, any risk that is unnecessary or not freely chosen is not acceptable'. There must be a move away from situations where prior, important decisions resulted in winners and losers; wealthy beneficiaries and underprivileged victims. There must be recognition that decision making needs to be inclusive, extensive and democratic and that the end products and final results are necessary and worthwhile before projects begin. They must be visible, accessible, and must reflect the cost of doing business which includes taking the time, finding the information and involving the people who will work together to make sure that harm is avoided and

A Population-Based Study of the Prevalence and Correlates of Self-Harm in Juvenile Detention.

Full Text Available Suicide is the number one cause of death among incarcerated youth. We examined the demographic and forensic risk factors for self-harm in youth in juvenile detention using a Canadian provincial correctional database.We analyzed data from de-identified youth aged 12 to 18 at the time of their offense who were in custody in a Manitoba youth correctional facility between January 1, 2005 and December 30, 2010 (N = 5,102. Univariate and multivariate logistic regression analyses determined the association between staff-identified self-harm events in custody and demographic and custodial variables. Time to the event was examined based on the admission date and date of event.Demographic variables associated with self-harm included female sex, lower educational achievement, older age, and child welfare involvement. Custodial variables associated with self-harm included higher criminal severity profiles, younger age at first incarceration, longer sentence length, disruptive institutional behavior, and a history of attempting escape. Youth identified at entry as being at risk for suicide were more likely to self-harm. Events tended to occur earlier in the custodial admission.Self-harm events tended to occur within the first 3 months of an admission stay. Youth with more serious offenses and disruptive behaviors were more likely to self-harm. Individuals with problematic custodial profiles were more likely to self-harm. Suicide screening identified youth at risk for self-harm. Strategies to identify and help youth at risk are needed.

Vigilance-avoidance and disengagement are differentially associated with fear and avoidant behaviors in social anxiety.

Individuals with Social Anxiety Disorder (SAD) often exhibit preferential attention for social threat, demonstrating abnormal orientation to threat (i.e., vigilance-avoidance) and/or difficulty disengaging from threat. However, no research has compared the relationship between attention indices (i.e., vigilance-avoidance, difficulty disengaging from threat) and characteristic features of the disorder such as fear during social situations (social fear) and avoidant behaviors (social avoidance). To address this issue, seventy adults (19.29±1.47 years, 33 females) were separated into low (n=37) or high (n=33) socially anxious groups using clinical cutoff scores on the Social Interaction Anxiety Scale (SIAS). Participants in both groups completed a dot-probe task with congruent, incongruent, and neutral trials to obtain measures of vigilance-avoidance and difficulty disengaging. Using linear regression, we examined the associations each attention index shared with self-reported social fear and social avoidance. Exclusively in the high anxious group, greater vigilance towards threat was associated with higher self-reported social fear, but not with social avoidance. However, difficulty disengaging was not associated with either social measure. In the low anxiety group, no relationships between attention indices and either social measure emerged. Future research with clinical samples is necessary to replicate and extend these findings. The small sample size studied may have limited our ability to detect other smaller effects. Indices of attention bias may contribute differently to the etiology and maintenance of SAD, which offers important implications for novel treatments that target attention.

Harm reduction through a social justice lens.

Science.gov (United States)

Pauly, Bernadette

2008-02-01

People who are street involved such as those experiencing homelessness and drug use face multiple inequities in health and access to health care. Morbidity and mortality are significantly increased among those who are street involved. Incorporation of a harm reduction philosophy in health care has the potential to shift the moral context of health care delivery and enhance access to health care services. However, harm reduction with a primary focus on reducing the harms of drug use fails focus on the harms associated with the context of drug use such as homelessness, violence and poverty. Ethical analysis of the underlying values of harm reduction and examination of different conceptions of justice are discussed as a basis for action that addresses a broad range of harms associated with drug use. Theories of distributive justice that focus primarily on the distribution of material goods are limited as theoretical frameworks for addressing the root causes of harm associated with drug use. Social justice, reconceptualised and interpreted through a critical lens as described by Iris Marion Young, is presented as a promising alternative ethical framework. A critical reinterpretation of social justice leads to insights that can illuminate structural inequities that contribute to the harms associated with the context of drug use. Such an approach provides promise as means of informing policy that aims to reduce a broad range of harms associated with drug use such as homelessness and poverty.

Varenicline and Risk of Self-Harm: A Nested Case-Control Study.

Mina Tadrous

Full Text Available Smoking remains a serious public health concern. Pharmacotherapy for smoking cessation, including bupropion and varenicline, are proven means to increase quit rates. Post-marketing reports describing suicidal behaviours have raised concerns about the safety of varenicline. However, whether varenicline imparts a higher risk of suicide relative to bupropion remains uncertain.A population-based nested case-control study in Ontario, Canada, from April 1, 2011 to March 31, 2015 was conducted. Subjects were residents of Ontario aged 18 years and older with publicly funded drug coverage receiving either bupropion or varenicline for smoking cessation. We defined cases were those with a hospitalization or emergency department visit for suicide or non-fatal self-harm within 90 days of treatment. For each case, we identified up to fifty controls from the same cohort matched on age, sex, history of self-harm, use of selected psychotropic medications, alcohol abuse and prior admission to a mental health unit. Adjusted odds ratio were used to compare the risk of suicide/self-harm of varenicline to bupropion.We identified 331 cases and 5,346 matched-controls. Following adjustment for potential confounders, we found that varenicline was not associated with an increased risk of suicide/self-harm relative to bupropion (adjusted odds ratio 1.15; 95% confidence interval 0.71 to 1.87.Treatment with varenicline does not appear to significantly increase the risk of suicide or self-harm relative to bupropion.

Coping styles adopted in stressful situations by self-harming adolescents

Full Text Available The state of stress and styles of coping with stress constitute an important component of life of every human being, particularly during adolescence. Effective coping mechanisms enable reduction of severity of stress experienced, while inability to manage stressful situations results in alterations in emotional and physiological domains, disturbances of mental well-being, somatic health and social functioning. Since a few years, we are witnessing a significant aggravation of the phenomenon of auto-aggression among children and adolescents, particularly in populations already undergoing psychiatric treatment. Such behaviours fulfil several functions: they may represent a way to express emotions, a means of adaptation or a style of coping with difficulties encountered in everyday life and emotional tension associated therewith. The aim of this study was to analyse predominating styles of coping with stressful situations, adopted by adolescen patients performing self-harm. The study population encompassed 35 patients, aged 16.60±0.18 years, there of 27 girls and 8 boys, hospitalised at the Department of Adolescent Psychiatry of the Medical University in Łódź, who had a history of deliberate self-harm (DSH. Control group included 32 healthy volunteers aged 16.91±0.16 years, thereof 23 girls and 9 boys. In view of the size of study population, it was subdivided into subgroups depending on whether episodes of DSH were sporadic or repetitive. Data were collected using the Coping Inventory for Stressful Situations (CISS. This questionnaire was designed specifically to explore styles of coping with stress. Self-harming adolescents, both girls and boys, significantly more often adopted emotion-oriented style. Patients with repetitive DSH (over 4 episodes significantly more often adopted emotion-oriented style and/or avoidance-oriented style, particularly in the form of seeking social contacts – social diversion, as compared with those committing

Avoiding maladaptation to climate change: towards guiding principles

International Nuclear Information System (INIS)

Magnan, Alexandre

2013-08-01

The recent publication of the Physical Science Basis volume of IPCC's Fifth Assessment Report reaffirms an already known conclusion: even drastic reductions of global greenhouse gas emissions will be insufficient to avoid some of the impacts of climate change, and is becoming increasingly clear that the temperature increase by the end of the century is likely to exceed the official target of +2 deg. C. Urgent efforts are thus more than ever needed to support socio-ecological systems threatened by climate change, but how to make adaptation happen on the ground remains vague. Consequently, there is a real risk that climate funding may support initiatives that are actually harmful for the socio-ecological systems, i.e. that foster adaptation in the short-term but insidiously affect systems' long-term vulnerability and/or adaptive capacity to climate change. This generally defines 'mal-adaptation', and this paper affirms that avoiding mal-adaptation is a first key concrete step towards adaptation in a broader sense. Focusing on coastal areas at a local scale and with the aim of providing insights to help avoiding mal-adaptation to climate change on the ground, this paper develops eleven practice-oriented guidelines that address the environmental, socio-cultural and economic dimensions of adaptation initiatives (policies, plans, projects). Based upon this, it affirms that the more guidelines an initiative addresses, the lower will be the risk of mal-adaptation. Together, these guidelines and this assumption constitute the 'Assessment framework' for approaching mal-adaptation to climate change at a local level. (author)

Risk factors for repetition of self-harm: a systematic review of prospective hospital-based studies.

Directory of Open Access Journals (Sweden)

Celine Larkin

Full Text Available BACKGROUND: Self-harm entails high costs to individuals and society in terms of suicide risk, morbidity and healthcare expenditure. Repetition of self-harm confers yet higher risk of suicide and risk assessment of self-harm patients forms a key component of the health care management of self-harm patients. To date, there has been no systematic review published which synthesises the extensive evidence on risk factors for repetition. OBJECTIVE: This review is intended to identify risk factors for prospective repetition of self-harm after an index self-harm presentation, irrespective of suicidal intent. DATA SOURCES: PubMed, PsychInfo and Scirus were used to search for relevant publications. We included cohort studies which examining factors associated with prospective repetition among those presenting with self-harm to emergency departments. Journal articles, abstracts, letters and theses in any language published up to June 2012 were considered. Studies were quality-assessed and synthesised in narrative form. RESULTS: A total of 129 studies, including 329,001 participants, met our inclusion criteria. Some factors were studied extensively and were found to have a consistent association with repetition. These included previous self-harm, personality disorder, hopelessness, history of psychiatric treatment, schizophrenia, alcohol abuse/dependence, drug abuse/dependence, and living alone. However, the sensitivity values of these measures varied greatly across studies. Psychological risk factors and protective factors have been relatively under-researched but show emerging associations with repetition. Composite risk scales tended to have high sensitivity but poor specificity. CONCLUSIONS: Many risk factors for repetition of self-harm match risk factors for initiation of self-harm, but the most consistent evidence for increased risk of repetition comes from long-standing psychosocial vulnerabilities, rather than characteristics of an index episode

To investigate whether schizophrenia patients with both suicide attempts and non-suicidal self-harm have earlier age of onset of psychotic and depressive symptoms and higher levels of clinical symptoms compared to patients with only suicide attempts or without suicide attempt. Using a cross-sectional design, 251 patients (18-61 years old, 58% men) with schizophrenia treated at hospitals in Oslo and Innlandet Hospital Trust, Norway, were assessed with a comprehensive clinical research protocol and divided into three groups based on their history of suicide attempts and non-suicidal self-harm. Suicide attempts were present in 88 patients (35%); 52 had suicide attempts only (29%) and 36 had both suicide attempts and non-suicidal self-harm (14%). When compared with nonattempters and those with suicide attempts without non-suicidal self-harm, patients with both suicide attempts and non-suicidal self-harm were more frequently women, younger at the onset of psychotic symptoms, had longer duration of untreated psychosis, and had higher levels of current impulsivity/aggression and depression. Patients with both suicide attempts and non-suicidal self-harm were more likely to repeat suicide attempts than patients with suicide attempts only. Patients with both suicide attempts and non-suicidal self-harm had different illness history and clinical characteristics compared to patients with only suicide attempts or patients without suicidal behavior. Our study suggests that patients with both suicide attempts and non-suicidal self-harm represent a distinct subgroup among patients with schizophrenia and suicidal behavior with their early onset of psychotic symptoms, high rate of repeated suicidal behavior and significant treatment delay.

Perceived harmfulness of substance use: A pilot study

Siddharth Sarkar

2014-01-01

Full Text Available Background: Harm ratings of substances help in understanding the perception toward substance use and formulating policies. Evidence of such harm ratings by substance users and their caregivers provides a clearer perspective of those who experience and observe such harm closely. Materials and Methods: Substance users and their caregivers were recruited from the Drug De-addiction and Treatment Centre of PGIMER, Chandigarh. Sociodemographic details of the subjects were noted. The subjects were then asked to rate a list of psychoactive preparations according to the harms they thought the preparation caused. The list of substances was developed taking into consideration substance commonly encountered in the geographical area. The harm ratings were transformed on a scale of 0-100. Results: All subjects were males and majority of them were educated above 10 th standard, were not employed and belonged to urban background. Most of them had taken psychoactive substances in their lifetimes but were currently abstinent. Most of the subjects endorsed intravenous drugs as the most harmful, followed by heroin. Beer and chewable tobacco considered the least harmful substances. Greater degree of education was associated with lower harm rankings for heroin, cannabis, dextropropoxyphene, and raw opium; while urban residence was associated with greater harm ratings for cannabis and raw opium. Differences in the harms were perceived for different preparations of the same active compound for alcohol and nicotine. Conclusion: Harm ratings of substances can be a useful guide while formulating policies and allocating resources. Need for further research extending this pilot study is emphasized.

Full Text Available The aims of this study were to describe fatal and non-fatal self-harm burdens, as well as burdens from the main preventable risk factors, and to investigate the different suicide methods in Hubei province in central China utilizing data from both Global Burden of Disease Study 2015 and Hubei Disease Surveillance Points system. All self-harm burdens including mortality, years of life lost (YLLs, prevalence, years lived with disability (YLDs, and disability adjusted life-years (DALYs consistently demonstrated downward trends in Hubei from 1990 to 2015, with a bigger decline gap observed among females and narrower decreasing amplitudes among the elderly. Hubei experienced much higher age-standardized rates for self-harm mortality (22.0 per 100,000, YLLs (560.1 per 100,000 and DALYs (563.9 per 100,000 than the national (9.0, 292.3 and 295.0 per 100,000 respectively and global levels (11.5, 453.3 and 457.9 per 100,000 respectively in 2015. Self-harm burdens have begun shifting from females to males and the elderly suffered more self-harm burdens than other age groups. Alcohol use accounted for 20.9% of all self-harm DALYs for males, whereas intimate partner violence accounted for 24.4% of all self-harm DALYs for females. Poisoning, mainly pesticide self-poisoning, was still the most common method of suicide. Effective interventions by multi-sectoral collaboration are urgently needed to reduce the alarmingly heavy self-harm burdens in Hubei.

Full text: In 1999, during the NATO attacks on Kosovo, from AT-10 aircraft has been shot over 50000 30-mm projectiles which contained approximately 15 tones of DU. Besides DU, projectiles contained products of DU radioactive decay as well as americium, neptunium, plutonium and technetium. Due to DU contamination military personnel employed near hit targets could be contaminated and irradiated. Besides the harmful effects in exposed military personnel, harmful effects were noticed in their offsprings, too. DU can cause genetic and teratogenic harmful effects in the embryos/fetus. It is concentrated in semen of contaminated males and also can contaminate the embryo/fetus through placenta. DU, as a toxic and radioactive element, can cause variety of harmful effects, but the most important are the effects on DNA which are the cause of many diseases. The aim of this paper is to examine is there any change in the incidence in heritable effects, congenital malformations, malignant diseases, endocrine and immune disorders. For that reason we compared the incidence of these diseases in the offspring's of military personnel born from 1995-1999 (1204) with the children born from 2000-2004 (1131) / and 2005-2008. Our results showed higher incidence of congenital malformations and chromosomal abnormalities (12.55 % vs 4.57 %), with highest incidence of foot deformity-52.04 % and hip deformity. These abnormalities were followed with immunological disorders and dysfunction of the urine bladder. Endocrine diseases were increased too(2.16 % :1.63 %). In this period higher incidence of malignant diseases was not noticed, but in the second period (from 5-9 year) after 1999, higher incidence of malignant hematological diseases was noticed, as well as Down Sy. During the conflicts future parents as well as embryo/fetus are exposed to many harmfulness and it is very hard to separate the influence of each. Considering the fact that the effects of DU, could be delayed and synergistic with

Personality traits are potential endophenotypes for genetic studies of psychiatric disorders. One personality theory which demonstrates strong heritability is Cloninger's psychobiological model measured using the temperament and character inventory (TCI). 277 individuals who completed the TCI questionnaire as part of the South Island Bipolar Study were also interviewed to assess for lifetime psychiatric diagnoses. Four groups were compared, bipolar disorder (BP), type 1 and 2, MDD (major depressive disorder), and nonaffected relatives of a proband with BP. With correction for mood state, total harm avoidance (HA) was higher than unaffected in both MDD and BP groups, but the mood disorder groups did not differ from each other. However, BP1 individuals had higher self-transcendence (ST) than those with MDD and unaffected relatives. HA may reflect a trait marker of mood disorders whereas high ST may be specific to BP. As ST is heritable, genes that affect ST may be of relevance for vulnerability to BP.

Full Text Available Abstract Background Balanced decisions about health care interventions require reliable evidence on harms as well as benefits. Most systematic reviews focus on efficacy and randomised trials, for which the methodology is well established. Methods to systematically review harmful effects are less well developed and there are few sources of guidance for researchers. We present our own recent experience of conducting systematic reviews of harmful effects and make suggestions for future practice and further research. Methods We described and compared the methods used in three systematic reviews. Our evaluation focused on the review question, study designs and quality assessment. Results One review question focused on providing information on specific harmful effects to furnish an economic model, the other two addressed much broader questions. All three reviews included randomised and observational data, although each defined the inclusion criteria differently. Standard methods were used to assess study quality. Various practical problems were encountered in applying the study design inclusion criteria and assessing quality, mainly because of poor study design, inadequate reporting and the limitations of existing tools. All three reviews generated a large volume of work that did not yield much useful information for health care decision makers. The key areas for improvement we identified were focusing the review question and developing methods for quality assessment of studies of harmful effects. Conclusions Systematic reviews of harmful effects are more likely to yield information pertinent to clinical decision-making if they address a focused question. This will enable clear decisions to be made about the type of research to include in the review. The methodology for assessing the quality of harmful effects data in systematic reviews requires further development.

Full Text Available Several studies examining leader–follower interaction in Greece, a collectivistic culture, paradoxically find that leaders’ emotion suppression-related personality traits (attachment avoidance, emotion suppression, emotion control are associated with followers’ positive emotional and work attitude outcomes. These findings have been explained with reference to followers’ implicit cultural schemas, interdependence in particular. Yet, this conjuncture has not been directly tested. The present study directly examined, in a field setting, how followers’ independent and interdependent (cultural self-construal moderate the relationship between leaders’ attachment orientation and followers’ emotion and satisfaction outcomes at the work place. As hypothesized, leaders’ higher avoidance was associated with followers’ job satisfaction, group cohesion, and deep acting as well as lower negative affect and loneliness for followers higher on interdependent self-construal. The results underline perceptual processes involved in followers’ interdependent self-construal in relation to leaders’ emotion suppression-related traits.

Background There is a lack of consensus about whether self-harm with suicidal intent differs in aetiology and prognosis from non-suicidal self-harm, and whether they should be considered as different diagnostic categories. Method Participants were 4799 members of the Avon Longitudinal Study of Parents and Children (ALSPAC), a UK population-based birth cohort who completed a postal questionnaire on self-harm with and without suicidal intent at age 16 years. Multinomial logistic regression analyses were used to examine differences in the risk factor profiles of individuals who self-harmed with and without suicidal intent. Results Many risk factors were common to both behaviours, but associations were generally stronger in relation to suicidal self-harm. This was particularly true for mental health problems; compared to those with non-suicidal self-harm, those who had harmed with suicidal intent had an increased risk of depression (OR 3.50[95% CI 1.64, 7.43]) and anxiety disorder (OR 3.50[95% CI 1.72, 7.13]). Higher IQ and maternal education were risk factors for non-suicidal self-harm but not suicidal self-harm. Risk factors that appeared specific to suicidal self-harm included lower IQ and socioeconomic position, physical cruelty to children in the household and parental self-harm. Limitations i) There was some loss to follow-up, ii) difficulty in measuring suicidal intent, iii) we cannot rule out the possibility of reverse causation for some exposure variables, iv) we were unable to identify the subgroup that had only ever harmed with suicidal intent. Conclusion Self-harm with and without suicidal intent are overlapping behaviours but with some distinct characteristics, indicating the importance of fully exploring vulnerability factors, motivations, and intentions in adolescents who self harm.

Piazza, Jared; Sousa, Paulo; Holbrook, Colin

2013-09-01

Three studies tested the conditions under which people judge utilitarian harm to be authority dependent (i.e., whether its right or wrongness depends on the ruling of an authority). In Study 1, participants judged the right or wrongness of physical abuse when used as an interrogation method anticipated to yield useful information for preventing future terrorist attacks. The ruling of the military authority towards the harm was manipulated (prohibited vs. prescribed) and found to significantly influence judgments of the right or wrongness of inflicting harm. Study 2 established a boundary condition with regards to the influence of authority, which was eliminated when the utility of the harm was definitely obtained rather than forecasted. Finally, Study 3 replicated the findings of Studies 1-2 in a completely different context-an expert committee's ruling about the harming of chimpanzees for biomedical research. These results are discussed as they inform ongoing debates regarding the role of authority in moderating judgments of complex and simple harm. Copyright © 2013 Elsevier B.V. All rights reserved.

The association between social relationships and self-harm: a case–control study in Taiwan

Science.gov (United States)

2013-01-01

Background Although suicide has been postulated as a result of social breakdown, relatively little attention has been paid to the association between social relationships and non-fatal self-harm. We sought to investigate the extent to which social factors correlate with self-harm in this case–control study. Methods The primary outcome was self-harm with hospital presentation. Cases of self-harm from the Emergency Department in a general hospital in Northern Taiwan were recruited, and individually age-and-gender-matched control participants were recruited from non-psychiatric outpatient clinics at the same hospital. The Close Persons Questionnaire was administered and its social support and social network subscales were used to measure social relationships in the 12 months prior to the interview. Other covariates, comprising sociodemographic factors, major life events, physical and mental health, were adjusted in conditional logistic regression models. Results A total of 124 case–control pairs were recruited. The mean (standard deviation) age of the case group was 34.7 (12.8) years and 80.6% were female. Higher social isolation score remained significantly associated with self-harm after adjustment (adjusted odds ratio per standard deviation increase 2.92, 95% confidence interval 1.44-5.95) and household size was negatively associated with the outcome (adjusted odds ratio per unit increase 0.54, 95% CI 0.32-0.94). Conclusions More limited social networks were associated with self-harm after adjustment for potential confounders. Enhancing social structure and effective networking of people with self-harm to community resources may be important for self-harm management in Asian societies and elsewhere. PMID:23531045

Geoengineering, Climate Harm, and Business as Usual

Science.gov (United States)

Jankunis, F. J.; Peacock, K.

2014-12-01

We define geoengineering (GE) as the intentional use of technology to change the planet's climate. Many people believe GE is different in kind rather than degree from any other organized activity in human history. In fact, humans caused changes in the planet's climate long before the industrial age, and all organisms engineer their environments directly or indirectly. The relevant difference between this cumulative and generally inadvertent activity and GE is the presence of intention. Now that science has revealed the extent to which humans can change the climate, however, even the continuance of Business as Usual (BAU) is, in effect, a form of intentional GE, albeit one that will cause significant climate harm, defined as effects such as sea level rise that will impact human well-being. But as with all forms of engineering, the devil is in the details: what forms of GE should be tried first? Some methods, such as large-scale afforestation, are low risk but have long-term payoffs; others, such as aerosol injection into the stratosphere, could help buy time in a warming crisis but have unknown side-effects and little long-term future. Climate change is a world-wide, inter-generational tragedy of the commons. Rational choice theory, the spatial and temporal extension of the problem, poorly fitted moral frameworks, and political maneuvering are all factors that inhibit solutions to the climate tragedy of the commons. The longer that such factors are allowed to dominate decision-making (or the lack thereof) the more likely it is that humanity will be forced to resort to riskier and more drastic forms of GE. We argue that this fact brings an additional measure of urgency to the search for ways to engineer the climate differently so as to avoid climate harm in the most lasting and least risky way.

How sacrifice impacts the giver and the recipient: insights from approach-avoidance motivational theory.

2014-10-01

This study investigated how sacrificing for approach versus avoidance goals shapes the giver's and the recipient's emotions and relationship quality. A sample of 80 dating couples participated in a three-part study in which they discussed sacrifice in the laboratory (Part 1), reported on their daily sacrifices for 14 days (Part 2), and completed a follow-up survey 3 months later (Part 3). When partners discussed a sacrifice they had made for approach goals, they experienced greater relationship quality, whereas when they discussed a sacrifice they had made for avoidance goals, they experienced poorer relationship quality. These effects were replicated with outside observer reports. On days when partners sacrificed for approach goals, both partners experienced increased relationship quality, but on days when people sacrificed for avoidance goals, the giver experienced decreased relationship quality. These effects were mediated by positive and negative emotions, respectively. Approach sacrifice goals predicted increases in relationship quality and avoidance sacrifice goals predicted decreases in relationship quality, as reported by both partners 3 months later. Sacrifice per se does not help or harm relationships, but the goals that people pursue when they give up their own interests can critically shape the quality of intimate bonds. © 2013 Wiley Periodicals, Inc.

Self-relevant disgust and self-harm urges in patients with borderline personality disorder and depression: a pilot study with a newly designed psychological challenge.

Full Text Available Borderline personality disorder (BPD is a common psychiatric condition associated with self-harm. Self-harm is poorly understood and there is currently no treatment for acute presentations with self-harm urges.By using a new task (Self-relevant Task; SRT, to explore emotions related to one's own person (PERSON task and body (BODY task, to study the correlations of these emotions, specifically disgust, with self-harm urge level changes, and to test the task's potential to be developed into an experimental model of self-harming for treatment trials.17 BPD patients, 27 major depressive disorder (MDD patients, and 25 healthy volunteers performed the SRT. Emotion labels were extracted from task narratives and disgust and self-harm urge level changes measured by visual analogue scales. We used validated rating scales to measure symptom severity.The SRT was effective at inducing negative emotions and self-harm urge changes. Self-harm urge changes correlated with borderline symptom severity. Post-task disgust levels on the visual analogue scales were higher in BPD patients than in healthy controls in the PERSON task, and higher than in both control groups in the BODY task. Changes in disgust levels during the task were significantly greater in the patient groups. Post-task disgust levels or changes in disgust were not associated with self-harm urge changes (except the latter in MDD in the PERSON task, but self-harm urge changes and disgust (but no other emotion narrative labels were on a whole sample level.Although associations with the analogue scale measures were not significant, self-disgust reported in the narrative of patients may be associated with a higher probability of self-harm urges. Further research with larger sample sizes is needed to confirm this relationship and to examine whether reducing self-disgust could reduce self-harm urges. The SRT was effective and safe, and could be standardized for experimental studies.

Full Text Available Harmful tax competition is not just tax system, but can also undermine the interests of local communities and the environment. Tax havens are a huge drain of resources from other countries (basic non tax haven to offshore areas. To operate, tax havens are supported economically, politically, and socially by high tax states. Also, by encouraging savings, it boosts investment and capital formation. Because they are low tax jurisdictions, they exert a higher tax on tax rates worldwide.

Caring for self-harming patients in general practice.

INTRODUCTION Intentional self-harm is an international public health issue with high personal, social and financial costs to society. Poor relationship dynamics are known to have a negative influence on the psyche of people who self-harm, and this can increase anxiety and decrease self-esteem, both shown to be significant contributors to self-harm behaviours. Positive and functional social supports have been proposed as a cost-effective and constructive approach in diminishing self-harming behaviours. AIM This qualitative study investigated the aspects of professional, social, familial and romantic relationships that people who have self-harmed identified as having a positive and constructive effect on their self-harm behaviour. METHODS Twelve participants with a history of self-harming behaviours were recruited through free press advertising in primary care and interviewed. The participants ranged in age from 19 to 70 years, and represented New Zealand (NZ) European and Māori from across the Southern region of NZ. RESULTS This study shows that constructive relationships that inhibit self-harm behaviours are characterised by participants' perceptions of authenticity in their relationships, and knowing that other people genuinely care. Feeling cared for within an authentic therapeutic relationship enabled participants to overcome their perception of being damaged selves and gave them the skills and confidence to develop functional relationships within their communities. A relationship-centred care approach may be useful for general practitioners seeking to develop more effective therapeutic relationships with patients who deliberately self-harm.

Avoiding boredom: Caudate and insula activity reflects boredom-elicited purchase bias.

Dal Mas, Dennis E; Wittmann, Bianca C

2017-07-01

People show a strong tendency to avoid boring situations, but the neural systems mediating this behavioural bias are yet unknown. We used functional magnetic resonance imaging (fMRI) to investigate how the anticipation of a boring task influences decisions to purchase entertainment. Participants accepted higher prices to avoid boredom compared to control tasks, and individual differences in boredom experience predicted the increase in price. This behavioural bias was associated with higher activity in the caudate nucleus during music purchases driven by boredom avoidance. Insula activation was increased during performance of the boring task and subsequently associated with individual differences in boredom-related decision making. These results identify a mechanism that drives decisions to avoid boring situations and potentially underlies consumer decisions. Copyright © 2017 Elsevier Ltd. All rights reserved.

Improved prediction of the "most harmful" breast cancers that cause the most substantive morbidity and mortality would enable physicians to target more intense screening and preventive measures at those women who have the highest risk; however, such prediction models for the "most harmful" breast cancers have rarely been developed. Electronic health records (EHRs) represent an underused data source that has great research and clinical potential. Our goal was to quantify the value of EHR variables in the "most harmful" breast cancer risk prediction. We identified 794 subjects who had breast cancer with primary non-benign tumors with their earliest diagnosis on or after 1/1/2004 from an existing personalized medicine data repository, including 395 "most harmful" breast cancer cases and 399 "least harmful" breast cancer cases. For these subjects, we collected EHR data comprised of 6 components: demographics, diagnoses, symptoms, procedures, medications, and laboratory results. We developed two regularized prediction models, Ridge Logistic Regression (Ridge-LR) and Lasso Logistic Regression (Lasso-LR), to predict the "most harmful" breast cancer one year in advance. The area under the ROC curve (AUC) was used to assess model performance. We observed that the AUCs of Ridge-LR and Lasso-LR models were 0.818 and 0.839 respectively. For both the Ridge-LR and LassoLR models, the predictive performance of the whole EHR variables was significantly higher than that of each individual component (pbreast cancer, providing the possibility to personalize care for those women at the highest risk in clinical practice.

Impulsivity and self-harm in adolescence: a systematic review.

Lockwood, Joanna; Daley, David; Townsend, Ellen; Sayal, Kapil

2017-04-01

Research supports an association between impulsivity and self-harm, yet inconsistencies in methodology across studies have complicated understanding of this relationship. This systematic review examines the association between impulsivity and self-harm in community-based adolescents aged 11-25 years and aims to integrate findings according to differing concepts and methods. Electronic searches of EMBASE, MEDLINE, PsychINFO, CINAHL, PubMed and The Cochrane Library, and manual searches of reference lists of relevant reviews identified 4496 articles published up to July 2015, of which 28 met inclusion criteria. Twenty-four of the studies reported an association between broadly specified impulsivity and self-harm. However, findings varied according to the conception and measurement of impulsivity and the precision with which self-harm behaviours were specified. Specifically, lifetime non-suicidal self-injury was most consistently associated with mood-based impulsivity-related traits. However, cognitive facets of impulsivity (relating to difficulties maintaining focus or acting without forethought) differentiated current self-harm from past self-harm. These facets also distinguished those with thoughts of self-harm (ideation) from those who acted on thoughts (enaction). The findings suggested that mood-based impulsivity is related to the initiation of self-harm, while cognitive facets of impulsivity are associated with the maintenance of self-harm. In addition, behavioural impulsivity is most relevant to self-harm under conditions of negative affect. Collectively, the findings indicate that distinct impulsivity facets confer unique risks across the life-course of self-harm. From a clinical perspective, the review suggests that interventions focusing on reducing rash reactivity to emotions or improving self-regulation and decision making may offer most benefit in supporting those who self-harm.

Beyond Sacrificial Harm: A Two-Dimensional Model of Utilitarian Psychology

Science.gov (United States)

2017-01-01

Recent research has relied on trolley-type sacrificial moral dilemmas to study utilitarian versus nonutilitarian modes of moral decision-making. This research has generated important insights into people’s attitudes toward instrumental harm—that is, the sacrifice of an individual to save a greater number. But this approach also has serious limitations. Most notably, it ignores the positive, altruistic core of utilitarianism, which is characterized by impartial concern for the well-being of everyone, whether near or far. Here, we develop, refine, and validate a new scale—the Oxford Utilitarianism Scale—to dissociate individual differences in the ‘negative’ (permissive attitude toward instrumental harm) and ‘positive’ (impartial concern for the greater good) dimensions of utilitarian thinking as manifested in the general population. We show that these are two independent dimensions of proto-utilitarian tendencies in the lay population, each exhibiting a distinct psychological profile. Empathic concern, identification with the whole of humanity, and concern for future generations were positively associated with impartial beneficence but negatively associated with instrumental harm; and although instrumental harm was associated with subclinical psychopathy, impartial beneficence was associated with higher religiosity. Importantly, although these two dimensions were independent in the lay population, they were closely associated in a sample of moral philosophers. Acknowledging this dissociation between the instrumental harm and impartial beneficence components of utilitarian thinking in ordinary people can clarify existing debates about the nature of moral psychology and its relation to moral philosophy as well as generate fruitful avenues for further research.

Full Text Available Introduction: Suicide is the third cause of mortality in America, second leading cause of death in developed countries, and one of the major health problems. Self-harm is self-inflicted damage to one’s self with or without suicidal intent. In the present study, the predictive factors of suicide attempt and non-suicidal self-harm were evaluated in patients referred to emergency department (ED with these problem. Methods: The total number of 45 patients with suicide attempt or self-harm admitted to ED were included. Clinical symptoms, thoughts and behaviors of suicidal, and non-suicidal self-harm in these patients were evaluated at baseline. Suicidality, suicidal intent and ideation, non-suicidal self-injury, social withdrawal, disruptive behavior, and poor family functions were evaluated at admission time. Brief clinical visits were scheduled for the twelfth weeks. In the twelfth week, patients returned for their final visit to determine their maintenance treatment. Finally data were analyzed using chi-squared and multiple logistic regression. Results: Forty five patients were included in the study (56.1% female. The mean age of patients was 23.3±10.2 years (range: 15-75; 33.3% married. Significant association of suicide and self-injury was presented at the baseline and in the month before attempting (p=0.001. The most important predictive factors of suicide and self-harm based on univariate analysis were depression (suicidal and non-suicidal items of Hamilton depression rating scale, anxiety, hopelessness, younger age, history of non-suicidal self-harm and female gender (p<0.05. The participants’ quality of life analysis showed a significant higher quality in physical component summary (p=0.002, mental component summary (p=0.001, and general health (p=0.001 at follow up period. Conclusion: At the time of admission in ED, suicide attempt and non-suicidal self-harm are subsequent clinical markers for the patient attempting suicide again. The

Getting out of (self-) harm's way: A study of factors associated with self-harm among asylum seekers in Australian immigration detention.

The monitoring of self-harm among asylum seekers in Australian immigration detention has not occurred routinely or transparently. Thus whilst concerns regarding rates of self-harm among asylum seekers have been frequently raised, a paucity of systematic information regarding key factors associated with self-harm among asylum seekers exists. The present study was designed therefore to fill a number of gaps in government monitoring by examining the government's own archived self-harm data. Via a descriptive analysis of self-harm incident reports from all operational Australian immigration detention facilities over a 20-month period to May 2011, obtained under Freedom of Information, the present study identified that 959 incidents of self-harm occurred during this period. A gender bias towards men was also found. In addition to this, 10 different methods of self-harm were identified, the four most common being: cutting (47%), attempted hanging (19%), head hitting (12%) and self-poisoning by medication (6%). Seven different precipitating factors for self-harm were also identified, the four most common were: detention conditions (39%), processing arrangements (27%), negative decisions (24%) and family separation (3%). These findings point strongly to the health benefits of considering alternatives to held immigration detention, such as community based processing.

Avoidance behavior against positive allergens detected by using multiple allergen simultaneous test (MAST)-immunoblot assay in patients with urticaria has been rarely reported. We aimed to assess the avoidance behavior of patients with urticaria against positive allergens detected with a MAST. One hundred and one urticaria patients who showed positivity to at least one allergen on a MAST completed a questionnaire regarding their test results. The avoidance behavior of the patients was evaluated, and relevant determining factors of avoidance success/failure were statistically assessed. We detected 144 different data (n=51, food allergens; n=17, pollen allergens; and n=76, aeroallergens) from 101 patients with urticaria. The avoidance failure rates were 33.3% for food allergens, 70.6% for pollen allergens, and 30.3% for aeroallergens. The pollen group showed a significantly higher avoidance failure rate than the food and aeroallergen groups (psuccessfully avoid allergens (psuccess or failure against allergens in patients with urticaria when clinicians conduct allergen-specific immunoglobulin E tests.

Researches often differentiate two groups of self-harming adolescents: those who attempters a suicide, and those who are harming themselves in a non-suicidal way, and they don‘t seek the death. However just a few community-based research, which would directly compare these groups, were done so far, and therefore information about the differences of the psychological peculiarity and self-harming behavior‘s internal factors between the groups is ambivalent.

Full Text Available Abstract The response to drug use in Laos has focused on reducing opium supply (supply reduction and rates of drug use (demand reduction. However, recently there is increased interest among government counterparts to discuss and develop broader responses to injecting drug use (IDU including the introduction of harm reduction programs. The concept of harm reduction has just been introduced to Lao PDR and as yet there is no agreement on a definition of the concept. We highlight here a range of issues that remain controversial in Lao PDR in the HIV, drug use and harm reduction discourse, the definition of 'harm reduction' and related terms; and the scope of harm reduction. This was a qualitative study, consisting of in-depth interviews with 27 law enforcement and 8 health officers who work in the fields of HIV and/or drug control about their understanding of HIV related to drug use, and concepts of harm reduction. Content analysis was performed to identify the coding, categories and themes. We found that law enforcement officers in particular had limited understanding about harm reduction and the feasibility and appropriateness of harm reduction services in the Lao context. Harm reduction should be a core element of a public health response to HIV where drug use and IDU exists. Recommendations include the necessity of increasing the awareness of harm reduction among law enforcement officers and providing appropriate evidence to support the needs of harm reduction policy and programs. HIV prevention and treatment strategies should be integrated within existing social and cultural frameworks, working with the task force for HIV/IDU and other government counterparts.

2017-01-01

Despite the growing consensus that negative reinforcement in the form of emotional relief plays a key role in the maintenance of deliberate self-harm (DSH), most of the research in this area has relied exclusively on self-report measures of the perceived motives for and emotional consequences of DSH. Thus, the primary aim of this study was to extend extant research on the role of emotional relief in DSH by examining the strength of the association of DSH with emotional relief using a novel version of the Implicit Association Test (IAT). The strength of the DSH-relief association among both participants with (vs. without) DSH and self-harming participants with (vs. without) BPD, as well as its associations with relevant clinical constructs (including DSH characteristics, self-reported motives for DSH, BPD pathology, and emotion dysregulation and avoidance) were examined in a community sample of young adults (113 with recent recurrent DSH; 135 without DSH). As hypothesized, results revealed stronger associations between DSH and relief among participants with versus without DSH, as well as among DSH participants with versus without BPD. Moreover, the strength of the DSH-relief association was positively associated with DSH frequency and versatility (both lifetime and at 6-month follow-up), BPD pathology, emotion dysregulation, experiential avoidance, and self-reported emotion relief motives for DSH. Findings provide support for theories emphasizing the role of emotional relief in DSH (particularly among individuals with BPD), as well as the construct validity, predictive utility, and incremental validity (relative to self-reported emotion relief motives) of this IAT.

Harmful Algal Blooms

Graham, Jennifer L.

2007-01-01

What are Harmful Algal Blooms (HABs)? Freshwater and marine harmful algal blooms (HABs) can occur anytime water use is impaired due to excessive accumulations of algae. HAB occurrence is affected by a complex set of physical, chemical, biological, hydrological, and meteorological conditions making it difficult to isolate specific causative environmental factors. Potential impairments include reduction in water quality, accumulation of malodorous scums in beach areas, algal production of toxins potent enough to poison both aquatic and terrestrial organisms, and algal production of taste-and-odor compounds that cause unpalatable drinking water and fish. HABs are a global problem, and toxic freshwater and (or) marine algae have been implicated in human and animal illness and death in over 45 countries worldwide and in at least 27 U.S. States (Yoo and others, 1995; Chorus and Bartram, 1999; Huisman and others, 2005).

Association between neurological soft signs, temperament and character in patients with schizophrenia and non-psychotic relatives

Directory of Open Access Journals (Sweden)

Liliana Galindo

2016-04-01

Full Text Available The heritability of schizophrenia and most personality traits has been well established, but the role of personality in susceptibility to schizophrenia remains uncertain. The aim of this study was to test for an association between personality traits and Neurological Soft Signs (NSS, a well-known biological marker of schizophrenia, in non-psychotic relatives of patients with schizophrenia. For this purpose, we evaluated the NSS scale and personality measured by the Temperament and Character inventory (TCI-R in three groups of subjects: 29 patients with schizophrenia, 24 unaffected relatives and 37 controls. The results showed that patients with schizophrenia were more asocial (higher harm avoidance and lower reward dependence, more perseverative (higher persistence, and more schizotypal (lower self-directedness and cooperativeness, higher self-transcendence. The unaffected relatives showed higher harm avoidance, lower self-directedness and cooperativeness than the healthy controls. Higher NSS scores and sub-scores were found in patients and non-psychotic relatives compared with the controls. Among all the patients, total NSS scores were positively correlated with harm avoidance but negatively correlated with novelty seeking and persistence. Total NSS were also correlated with low scores on self-directedness and cooperativeness, which are indicators of personality disorder. Our results show that susceptibility to NSS and to schizophrenia are both related to individual differences in the temperament and character features in non-psychotic relatives of patients with schizophrenia. High harm avoidance, low persistence, low self-directedness and low cooperativeness contribute to both the risk of NSS and schizophrenia. These findings highlight the value of using both assessments to study high risk populations.

Complete text of publication follows. Objective: Drinking water, water used in food production and for irrigation, water for fish farming, waste water, surface water, and recreational water have been recently recognized as a vector for the transmission of harmful micro-organisms. The human and animal harmful algae is a waterborne risk to public health and economy because the algae are ubiquitous and persistent in water and wastewater, not completely removed by physical-chemical treatment processes, and relatively resistant to chemical disinfection. Gamma and electron beam radiation technology is of growing in the water industry since it was demonstrated that gamma and electron beam radiation is very effective against harmful algae. Materials and Methods: Harmful algae (Scenedesmus quadricauda(Turpin) Brebisson 1835 (AG10003), Chlorella vulgaris Beijerinck 1896 (AG30007) and Chlamydomonas sp. (AG10061)) were distributed from Korean collection for type cultures (KCTC). Strains were cultured aerobically in Allen's medium at 25□ and 300 umol/m2s for 1 week using bioreactor. We investigated the disinfection efficiency of harmful algae irradiated with gamma (0.05 to 10 kGy for 30 min) and electron beam (1 to 19 kGy for 5 sec) rays. Results and Conclusion: We investigated the disinfection efficiency of harmful algae irradiated with gamma and electron beam rays of 50 to 19000 Gy. We established the optimum sterilization condition which use the gamma and electron beam radiation. Gamma ray disinfected harmful algae at 400 Gy for 30 min. Also, electron beam disinfected at 1000 Gy for 5 sec. This alternative disinfection practice had powerful disinfection efficiency. Hence, the multi-barrier approach for drinking water treatment in which a combination of various disinfectants and filtration technologies are applied for removal and inactivation of different microbial pathogens will guarantee a lower risk of microbial contamination.

Reducing the harms associated with risk assessments

International Nuclear Information System (INIS)

Montague, Peter

2004-01-01

Risk assessments are the intellectual products of dedicated public health and environmental professionals. Like many other products, risk assessments carry with them the potential for both good and harm. This paper briefly examines some of the harms to which risk assessments have contributed, and then suggests that the legal 'duty to warn' doctrine offers a logical and practical way to reduce some of these harms. The paper suggests concepts that could be incorporated into warnings accompanying every formal risk assessment as routine 'boiler plate' addenda, just as other potentially harmful products, such as lawn mowers and cook stoves, are accompanied by warnings. Finally, the paper briefly examines the 'Code of Ethics and Standards of Practice for Environmental Professionals' (promulgated by the National Association of Environmental Professionals) and shows that the suggested warnings are consistent with recommended practices for environmental professionals

E-cigarettes are frequently advertised and portrayed in the media as less harmful compared with regular cigarettes. Earlier surveys reported public perceptions of harms to people using e-cigarettes; however, public perceptions of harms from exposure to secondhand vapour (SHV) have not been studied. We examined associations between self-reported exposure to e-cigarette advertising, media coverage, and interpersonal discussion and perceived harms of SHV. Observational study. National online sample of US adults aged ≥18 years. 1449 US adults (mean age 49.5 years), 51.3% female, 76.6% non-Hispanic Caucasian, 7.5% African-American, 10.0% Hispanic and 5.9% other races. Perceived harm measures included (1) harmfulness of SHV to one's health, (2) concern about health impact of breathing SHV and (3) comparative harm of SHV versus secondhand smoke (SHS). Predictors were (1) self-reported frequency of exposure to e-cigarette advertising, media coverage and interpersonal discussion (close friends or family) and (2) perceived valence of exposure from each source. Covariates were demographic characteristics, cigarette smoking status and e-cigarette use, and were weighted to the general US adult population. More frequent interpersonal discussion was associated with lower perceived harmfulness of SHV to one's health and lower perceived comparative harm of SHV versus SHS. Frequency of e-cigarette ad and other media exposure were not significant predictors. Perceived negative valence of ad exposure and interpersonal discussion (vs no exposure) was associated with higher perceived harm across all three outcomes, while negative valence of media coverage was associated with higher concern about health impact of breathing SHV. Perceived positive valence (vs no exposure) of interpersonal discussion was associated with lower perceived harm across all three outcomes about health impact of breathing SHV. Exposure to information about e-cigarettes through advertising, media coverage

Economic recessions are associated with increases in suicide rates but there is little information for non-fatal self-harm. To investigate the impact of the recent recession on rates of self-harm in England and problems faced by patients who self-harm. Analysis of data from the Multicentre Study of Self-harm in England for 2001-2010 and local employment statistics for Oxford, Manchester and Derby, including interrupted time series analyses to estimate the effect of the recession on rates of self-harm. Rates of self-harm increased in both genders in Derby and in males in Manchester in 2008-2010, but not in either gender in Oxford, results which largely followed changes in general population unemployment. More patients who self-harm were unemployed in 2008-10 compared to before the recession. The proportion in receipt of sickness or disability allowances decreased. More patients of both genders had employment and financial problems in 2008-2010 and more females also had housing problems, changes which were also largely found in employed patients. We have assumed that the recession began in 2008 and information on problems was only available for patients having a psychosocial assessment. Increased rates of self-harm were found in areas where there were greater rises in rates of unemployment. Work, financial and housing problems increased in people who self-harmed. Changes in welfare benefits may have contributed. None. Copyright © 2015 Elsevier B.V. All rights reserved.

Can harmful tax competition be curbed at the international level?

Energy Technology Data Exchange (ETDEWEB)

Gjersti, Per O. [Finans- og Tolldepartementet, Oslo (Norway)

1998-07-01

This presentation discusses the following issues: (1) Good vs harmful tax competition?, (2) How to identify harmful competition?, (3) What is the economic and social impact of harmful tax competition?, (4) What can be done about harmful tax competition? There are three levels, the EU level, the OECD level and the global level. Existing measures to counteract harmful tax practices are insufficient because action by one country merely shifts activity to another country and puts its tax payers at a competitive disadvantage and because coordination action eases political pressure. The EU code of good conduct and the OECD guidelines for dealing with harmful preferential tax regimes are compared, with respect to general features, with respect to key factors to identify harmful measures, and with respect to general scope.

[Beginners' operations and medical specialist standards : Avoidance of criminal liability and civil liability].

Science.gov (United States)

Schneider, H

2018-05-16

In all phases, patients are entitled to receive medical treatment according to medical specialist standards. This does not mean that patients necessarily have to be treated by a medical specialist. Operations performed by "beginners", e. g. assistant physicians, are permitted. However, there are increased liability risks, both for the specialist and the assistant physician. Furthermore, there are risks of criminal responsibility for causing bodily harm by negligence or negligent manslaughter. This article portrays the requirements of civil liability and criminal responsibility concerning beginners' operations on the basis of cases and judgments of the Federal Court and the Higher Regional Courts in Germany. Additionally, the reception of the jurisprudence by the relevant legal literature will be discussed. Jurisprudence and legal literature categorize breaches of duty of care. Assistant physicians can be subject to contributory negligence liabilities, while specialists can bear liabilities for negligent selection, organization or supervision. Responsible specialist and assistant physicians can protect themselves (and the patient) and avoid legal risks by only performing operations adequate to their educational level or by delegating operations to beginners and ensuring intervention by a specialist by supervision of the operation which is suitable to the assistant physician's level of education.

Islam and harm reduction.

Science.gov (United States)

Kamarulzaman, A; Saifuddeen, S M

2010-03-01

Although drugs are haram and therefore prohibited in Islam, illicit drug use is widespread in many Islamic countries throughout the world. In the last several years increased prevalence of this problem has been observed in many of these countries which has in turn led to increasing injecting drug use driven HIV/AIDS epidemic across the Islamic world. Whilst some countries have recently responded to the threat through the implementation of harm reduction programmes, many others have been slow to respond. In Islam, The Quran and the Prophetic traditions or the Sunnah are the central sources of references for the laws and principles that guide the Muslims' way of life and by which policies and guidelines for responses including that of contemporary social and health problems can be derived. The preservation and protection of the dignity of man, and steering mankind away from harm and destruction are central to the teachings of Islam. When viewed through the Islamic principles of the preservation and protection of the faith, life, intellect, progeny and wealth, harm reduction programmes are permissible and in fact provide a practical solution to a problem that could result in far greater damage to the society at large if left unaddressed.

2012-01-01

Adopting a higher harmonic cavity on a synchrotron radiation facility can increase the beam lifetime and suppress the beam instability. In this paper, we report the simulation and preliminary design on higher order modes (HOMs) damping of the designed and fabricated higher harmonic superconducting cavity for Shanghai Synchrotron Radiation Facility (SSRF). The requirements for the HOM damping are analyzed, and the length and location of the HOM damper are optimized by using the SEAFISH code. The results show that the design can provide heavy damping for harmful HOMs with decreased impedance, and the beam instability requirement of SSRF can be satisfied. By using the ABCI code, the loss factor is obtained and the HOM power is estimated. (authors)

To study the nature of deliberate self-harm (DSH) in children and to identify the associated factors. Child Guidance Clinic attached to the Department of Pediatrics of a teaching hospital in South India. Children with history of deliberate self harm who were referred to the CGC for psychological evaluation during a 10 year period. Children and parents were interviewed together and separately and details regarding age, sex, family and school environment, stresses and nature of self harm were documented. Psychiatric diagnosis was made based on DSM IV diagnostic criteria. Among the 30 children included in the study, 21 were boys and 9 were girls. Majority of children were between the ages of 11 and 13 years, the youngest being 6 years old. 76%of children had history of acute stressful life events and 62%of them had chronic ongoing stress. 62%of children had stress in the family and 41%had stress at school. Stress in the family included death of a parent, conflicts with parents or siblings, mental illness in the family, parental alcoholism and parental disharmony. Stress at school included conflicts with classmates, punishment or negative comments by teachers and learning problems. Psychiatric disorders were present in 52%of children, the commonest being depressive disorder. The commonest mode of DSH was self poisoning, and rat poison (zinc phosphide) was the commonest substance used. Deliberate self harm occurs in young children and the risk factors are comparable to those in adolescents.

Gambling has quickly emerged as an important global public health issue. With new technologies used to develop high intensity gambling products and promotions aimed at driving consumption, public health organisations and researchers, community groups, and politicians have argued for a range of regulatory and education measures aimed at reducing gambling harm. However, there has been limited research seeking to understand community perceptions of the harms associated with gambling products and environments, and the level of community support for strategies designed to prevent and reduce gambling harm. An online study of 500 adolescents and adults (aged 16 and over) was conducted with a representative sample (by age and gender) of individuals who were current residents in the state of Victoria, Australia. Participants were asked a range of questions about their own gambling behaviours, with the Problem Gambling Severity Index (PGSI) used as a measure of problem gambling. Participants were asked about their perceptions of harms associated with electronic gambling machines (EGMs), sports betting, horse betting, and casino gambling. They were also asked about the extent to which they agreed or disagreed with gambling harm reduction strategies related to marketing and promotions, restrictions on gambling products and venues, and public education campaigns. Quantitative data were analysed using descriptive statistics and paired t tests, with thematic analysis used to interpret qualitative responses to open-ended questionnaire items. More than one third (n = 201, 40.2%) of participants were at risk of experiencing some level of harm from gambling (PGSI ≥ 1), with 83 participants (16.6%) recording scores that indicated problem gambling (PGSI ≥ 8). One in five participants gambled on EGMs at least monthly (n = 100, 20.0%). Those who gambled on sports did so frequently, with nearly 1 in 5 gambling on sport at least once a month (n = 87, 17.4%).

The role of interpersonal harm in distinguishing regret from guilt.

Science.gov (United States)

Zeelenberg, Marcel; Breugelmans, Seger M

2008-10-01

Regret and guilt are emotions that are produced by negative outcomes for which one is responsible. Both emotions have received ample attention in the psychological literature; however, it is still unclear to what extent regret and guilt represent distinct psychological processes. We examined the extent to which the distinction between interpersonal harm (negative outcomes for others) and intrapersonal harm (negative outcomes for self) is crucial in differentiating these two emotions. In a series of 3 studies we found that guilt is predominantly felt in situations of interpersonal harm, whereas regret is felt in both situations of interpersonal harm and intrapersonal harm. Moreover, the results show that in situations of interpersonal harm the phenomenology of regret shares many, but not all features with the phenomenology of guilt. We conclude that the emotion processes resulting from interpersonal and intrapersonal harm are clearly distinct, but that regret as an emotion label is applied to both types of processes whereas the emotion label guilt is primarily used to refer to experiences of interpersonal harm. Implications for emotion research are discussed. (c) 2008 APA, all rights reserved

Differences in avoidable mortality between migrants and the native Dutch in the Netherlands

Directory of Open Access Journals (Sweden)

Bos V

2006-03-01

Full Text Available Abstract Background The quality of the healthcare system and its role in influencing mortality of migrant groups can be explored by examining ethnic variations in 'avoidable' mortality. This study investigates the association between the level of mortality from 'avoidable' causes and ethnic origin in the Netherlands and identifies social factors that contribute to this association. Methods Data were obtained from cause of death and population registries in the period 1995–2000. We compared mortality rates for selected 'avoidable' conditions for Turkish, Moroccan, Surinamese and Antillean/Aruban groups to native Dutch. Results We found slightly elevated risk in total 'avoidable' mortality for migrant populations (RR = 1.13. Higher risks of death among migrants were observed from almost all infectious diseases (most RR > 3.00 and several chronic conditions including asthma, diabetes and cerebro-vascular disorders (most RR > 1.70. Migrant women experienced a higher risk of death from maternity-related conditions (RR = 3.37. Surinamese and Antillean/Aruban population had a higher mortality risk (RR = 1.65 and 1.31 respectively, while Turkish and Moroccans experienced a lower risk of death (RR = 0.93 and 0.77 respectively from all 'avoidable' conditions compared to native Dutch. Control for demographic and socioeconomic factors explained a substantial part of ethnic differences in 'avoidable' mortality. Conclusion Compared to the native Dutch population, total 'avoidable' mortality was slightly elevated for all migrants combined. Mortality risks varied greatly by cause of death and ethnic origin. The substantial differences in mortality for a few 'avoidable' conditions suggest opportunities for quality improvement within specific areas of the healthcare system targeted to disadvantaged groups.

To Feel or Not to Feel When My Group Harms Others? The Regulation of Collective Guilt as Motivated Reasoning.

Science.gov (United States)

Sharvit, Keren; Brambilla, Marco; Babush, Maxim; Colucci, Francesco Paolo

2015-09-01

Four studies tested the proposition that regulation of collective guilt in the face of harmful ingroup behavior involves motivated reasoning. Cognitive energetics theory suggests that motivated reasoning is a function of goal importance, mental resource availability, and task demands. Accordingly, three studies conducted in the United States and Israel demonstrated that high importance of avoiding collective guilt, represented by group identification (Studies 1 and 3) and conservative ideological orientation (Study 2), is negatively related to collective guilt, but only when mental resources are not depleted by cognitive load. The fourth study, conducted in Italy, demonstrated that when justifications for the ingroup's harmful behavior are immediately available, the task of regulating collective guilt and shame becomes less demanding and less susceptible to resource depletion. By combining knowledge from the domains of motivated cognition, emotion regulation, and intergroup relations, these cross-cultural studies offer novel insights regarding factors underlying the regulation of collective guilt. © 2015 by the Society for Personality and Social Psychology, Inc.

Self-harming in depressed patients: pattern analysis.

Parker, G; Malhi, Gin; Mitchell, Philip; Kotze, Beth; Wilhelm, Kay; Parker, Kay

2005-10-01

As deliberate self-harm (DSH) is a common concomitant of depressive disorders, we undertook a study examining the relevance of possible determinants and correlates of DSH. Three separate samples of depressed outpatients were studied to determine consistency of identified factors across samples, with principal analyses involving gender, age and diagnosis-matched DSH and non-DSH subjects. Across the samples, some 20% of subjects admitted to episodes of DSH. Women reported higher rates and there was a consistent trend for higher rates in bipolar patients. Univariate analyses examined the relevance of several sociodemographic variables, illicit drug and alcohol use, past deprivational and abusive experiences, past suicidal attempts and disordered personality functioning. Multivariate analyses consistently identified previous suicide attempts and high 'acting out' behaviours across the three samples, suggesting the relevance of an externalizing response to stress and poor impulse control. Results assist the identification and management of depressed patients who are at greater risk of DSH behaviours.

Treasure, Janet; Crane, Anna; McKnight, Rebecca; Buchanan, Emmakate; Wolfe, Melissa

2011-01-01

The aim of this paper is to reflect on the way that we as clinicians may play an inadvertent role in perpetuating eating disordered behaviour. This is considered within the theoretical framework of Schmidt and Treasures' maintenance model of anorexia nervosa (AN). The model includes four main domains; interpersonal factors, pro-AN beliefs, emotional style and thinking style. Interpersonal reactions are of particular relevance as clinicians (as with family members) may react with high expressed emotion and unknowingly encourage eating disorder behaviours to continue. Hostility in the form of coercive refeeding in either a hospital or outpatient setting may strengthen conditioned food avoidance and pessimism may hamper motivation to change. Negative schema common to eating disorders, for example low self-esteem, perfectionism and striving for social value may augment existing or initiate new eating disorder behaviour. Services can become a reinforcing influence by providing an overly protective, palliating environment which ensures safety, security and acceptance whilst reducing loneliness and isolation. This stifles the need for an individual to develop their own sense of responsibility, autonomy and independence allowing avoidance to dominate. Furthermore, the highly structured environment of inpatient care supports the rigid attention to detail and inflexibility that is characteristic of people with eating disorders, and allows these negative behaviours to thrive. Careful planning of service provision, reflective practice, supervision and regular team feedback is essential to prevent iatrogenic harm.

Delayed medical care has negative health and economic consequences; interventions have focused on appraising symptoms, with limited success in reducing delay. To identify predictors of care avoidance and reasons for avoiding care. Using the Health Information National Trends Survey (2007), we conducted logistic regressions to identify predictors of avoiding medical visits deemed necessary by the respondents; and, we then conducted similar analyses on reasons given for avoidance behavior. Independent variables included geographic, demographic, socioeconomic, personal health, health behavior, health care system, and cognitive characteristics. Approximately one third of adults avoided doctor visits they had deemed necessary. Although unadjusted associations existed, avoiding needed care was not independently associated with geographic, demographic, and socioeconomic characteristics. Avoidance behavior is characterized by low health self-efficacy, less experience with both quality care and getting help with uncertainty about health, having your feelings attended to by your provider, no usual source of care, negative affect, smoking daily, and fatalistic attitude toward cancer. Reasons elicited for avoidance include preference for self-care or alternative care, dislike or distrust of doctors, fear or dislike of medical treatments, time, and money; respondents also endorsed discomfort with body examinations, fear of having a serious illness, and thoughts of dying. Distinct predictors distinguish each of these reasons. Interventions to reduce patient delay could be improved by addressing the health-related behavioral, belief, experiential, and emotional traits associated with delay. Attention should also be directed toward the interpersonal communications between patients and providers.

The harm argument against surrogacy revisited: two versions not to forget.

Science.gov (United States)

Agnafors, Marcus

2014-08-01

It has been a common claim that surrogacy is morally problematic since it involves harm to the child or the surrogate-the harm argument. Due to a growing body of empirical research, the harm argument has seen a decrease in popularity, as there seems to be little evidence of harmful consequences of surrogacy. In this article, two revised versions of the harm argument are developed. It is argued that the two suggested versions of the harm argument survive the current criticism against the standard harm argument. The first version argues that the child is harmed by being separated from the gestational mother. The second version directs attention to the fact that surrogacy involves great incentives to keep the gestational mother's level of maternal-fetal attachment low, which tend to increase the risk of harm to the child. While neither of the two arguments is conclusive regarding the moral status of surrogacy, both constitute important considerations that are often ignored.

To measure the extent of patient harm caused by medications (rate of Adverse Drug Events) in three DHBs, using a standardised trigger tool method. Counties Manukau, Capital and Coast and Canterbury DHBs decided to work collaboratively to implement the ADE Trigger Tool (TT). Definitions of ADE were agreed on and triggers refined. A random sample of closed charts (from March 2010 to February 2011) was obtained excluding patients who were admitted for <48 hours, children under the age of 18 and psychiatric admissions. In each DHB trained reviewers scanned these in a structured way to identify any of the 19 triggers. If triggers were identified, a more detailed, though time-limited review of the chart was done to determine whether an ADE had occurred. The severity of patient harm was categorised using the National Coordinating Council for Medication Error Reporting and Prevention Index. No attempt was made to determine preventability of harm and ADEs from acts of omission were excluded. The ADE TT was applied to 1210 charts and 353 ADE were identified, with an average rate of 28.9/100 admissions and 38/1,000 bed days. 94.5% of the ADE identified were in the lower severity scales with temporary harm, however in 5 patients it was considered that the ADE contributed to their death, 9 required an intervention to sustain life and 4 suffered permanent harm. The most commonly implicated drugs were morphine and other opioids, anticoagulants, antibiotics, Non Steroidal Anti-Inflammatory Drugs (NSAIDs) and diuretics. Patients who suffered an ADE were more likely to be female, older with more complex medical illnesses, and have a longer length of stay. The rate of medication-related harm identified by the ADE TT is considerably higher than that identified through traditional voluntary reporting mechanisms. The ADE TT provides a standardised measure of harm over time that can be used to determine trends and the effect of medication safety improvement programmes. This study not

Failure to resolve peer conflict is associated with children's reports of loneliness, social anxiety, and social avoidance. Although these relationships are well established, researchers have not examined the association between the avoidance of peer conflict and various adjustment characteristics. The current study examined the association between avoidance of conflict and measures of loneliness, social anxiety, and social avoidance for 59 pupils in Grade 4 (31 boys and 28 girls) and 47 in Grade 8 (22 boys and 25 girls). Volunteers indicated that conflict avoidance based on autonomy, e.g., independence issues, and interpersonal issues, e.g., closeness and cohesion, was associated with scores on loneliness for boys and girls, respectively. Conflict avoidance for emotional and physical well-being and fear of punishment was associated with increased reports of loneliness and social anxiety for children in Grade 4.

"I'd only let you down": Guilt proneness and the avoidance of harmful interdependence.

Science.gov (United States)

Wiltermuth, Scott S; Cohen, Taya R

2014-11-01

Five studies demonstrated that highly guilt-prone people may avoid forming interdependent partnerships with others whom they perceive to be more competent than themselves, as benefitting a partner less than the partner benefits one's self could trigger feelings of guilt. Highly guilt-prone people who lacked expertise in a domain were less willing than were those low in guilt proneness who lacked expertise in that domain to create outcome-interdependent relationships with people who possessed domain-specific expertise. These highly guilt-prone people were more likely than others both to opt to be paid on their performance alone (Studies 1, 3, 4, and 5) and to opt to be paid on the basis of the average of their performance and that of others whose competence was more similar to their own (Studies 2 and 5). Guilt proneness did not predict people's willingness to form outcome-interdependent relationships with potential partners who lacked domain-specific expertise (Studies 4 and 5). It also did not predict people's willingness to form relationships when poor individual performance would not negatively affect partner outcomes (Study 4). Guilt proneness therefore predicts whether, and with whom, people develop interdependent relationships. The findings also demonstrate that highly guilt-prone people sacrifice financial gain out of concern about how their actions would influence others' welfare. As such, the findings demonstrate a novel way in which guilt proneness limits free-riding and therefore reduces the incidence of potentially unethical behavior. Lastly, the findings demonstrate that people who lack competence may not always seek out competence in others when choosing partners.

Suicide is a major social and clinical problem in Asia. Although studies have suggested that personality traits are possible risk factors for suicide, no study has been conducted among Chinese to compare the temperament traits of suicidal and non-suicidal mood disorder patients with those of healthy controls. This study compared temperament traits of two patient groups, those with a mood disorder who have attempted suicide (n=204), and those with a mood disorder who have not attempted suicide (n=160), and compared the traits of these patients to those of healthy controls (n=178), assessed by Cloninger's Tridimensional Personality Questionnaire and the Brown-Goodwin Aggression Inventory. Patients with suicidal attempts had significantly higher novelty seeking and aggression scores than healthy controls and patients without suicidal attempts. Two groups of patients with mood disorder had significantly higher harm avoidance scores than the healthy controls. However, patients with suicidal attempts did not have higher harm avoidance scores than patients without suicidal attempts. This study confirms findings that harm avoidance and mood disorder are related, and extends them by suggesting that those with a mood disorder and suicide attempts have higher novelty seeking and lifetime aggression scores than those without suicidal attempt, either patients or healthy controls.

Studies comparing temperament and character traits between patients with mood disorders and healthy individuals have yielded variable results. The Temperament and Character Inventory (TCI) was administered to 101 bipolar I (BP-I), 96 bipolar II (BP-II), 123 major depressive disorder (MDD) patients, and 125 HS. A series of generalized linear models were performed in order to: (a) compare the TCI dimensions across groups; (b) test any effect of the TCI dimensions on clinical features of mood disorders; and (c) detect any association between TCI dimensions and the psychopathological features of a major depressive episode. Demographic and clinical variables were also included in the models as independent variables. Higher Harm Avoidance was found in BP-II and MDD, but not in BP-I. Higher Self-Transcendence was found in BP-I. Our models also showed higher Self-Directedness in HS, either vs MDD or BP-II. No association was found between any TCI dimension and the severity of symptoms. Conversely, a positive association was found between Harm Avoidance and the overall burden of depressive episodes during lifetime. The cross-sectional design and the heterogeneity of the sample may be the main limitations of our study. In general, our sample seems to support the view of a similar profile of temperament and character between MDD and BP-II, characterized by high Harm Avoidance and low Self-Directedness. In contrast, patients with BP-I only exhibit high Self-Transcendence, having a near-normal profile in terms of Harm Avoidance or Self-Directedness. Copyright © 2015 Elsevier B.V.

The prevalence of adolescent self-harm in Northern Ireland (NI) and its associated factors are unknown. Given the established relationship between conflict and mental health, and NI׳s recent history of conflict, it is important to investigate the factors associated with self-harm in NI. This study aimed to determine the prevalence of self-harm in NI adolescents and the factors associated with it, including exposure to the NI conflict. Observational study of 3596 school pupils employing an anonymous self-report survey. Information was obtained on demographic characteristics, lifestyle, life events and problems, exposure to the NI conflict, social and internet influences, and psychological variables. Self-harm was reported by 10% of respondents. In univariate analyses, exposure to the NI conflict was associated with self-harm alongside established risk factors. In multivariate analyses, bullying and exposure to self-harm were associated with lifetime self-harm in both girls and boys. Alcohol use, drug use, physical and sexual abuse, and self-esteem were also associated with self-harm in girls. In boys, absence of exercise, sexual orientation concerns, anxiety and impulsivity were additional risk factors. The internet/social media and the self-harm of others were also key influences. This is a cross-sectional study. The rate of self-harm was lower than elsewhere in the UK/Ireland. The study highlights the factors which should be considered in terms of risk assessment. In addition to established risk factors, the findings suggest that more research on the legacy of the NI conflict as well as the influence of new technologies warrant urgent attention.

Recent self-harm and psychological measures in the emergency department

Directory of Open Access Journals (Sweden)

Jason R. Randall

2014-11-01

Full Text Available The assessment of self-harm risk is a common, difficult, and perplexing task for many physicians, especially those working in emergency departments (ED. Attempts have been made to determine objective methods for assessing patients with suicidal ideation or self-harm though there is still a lack of knowledge about objective assessments of these patients. A study was conducted where 181 suicidal patients were enrolled in two EDs within the city of Edmonton, Canada. Initial interviews were conducted in the ED which collected basic demographics and medical history as well as psychometric measures including the Beck Hopelessness Scale, Barratt Impulsiveness Scale, Brief Symptom Inventory, Drug Abuse Screening Test 10, and CAGE questionnaire. The results of these measures were compared between those who presented to the ED with self-harm and those who presented only with ideation. Those with recent self-harm scored lower on many of the scales and subscales of distress and impulsivity measured compared to those with no recent self-harm. Possible explanations for this difference include differences in psychological traits between the two groups and possible cathartic effects of self-harm. The lower scores obtained by those that present with self-harm may complicate attempts to use psychometric tools to determine future self-harm risk.

Negative and positive externalities in intergroup conflict: exposure to the opportunity to help the outgroup reduces the inclination to harm it.

Science.gov (United States)

Weisel, Ori

2015-01-01

Outgroup hate, in the context of intergroup conflict, can be expressed by harming the outgroup, but also by denying it help. Previous work established that this distinction-whether the externality on the outgroup is negative or positive-has an important effect on the likelihood of outgroup hate emerging as a motivation for individual participation in intergroup conflict. The current work uses a within-subject design to examine the behavior of the same individuals in intergroup conflict with negative and positive externalities on the outgroup. Each participant made two choices, one for each type of externality, and the order was counter balanced. The main results are that (1) behavior is fairly consistent across negative and positive externalities, i.e., the tendency to display outgroup hate by harming the outgroup is correlated with the tendency to display outgroup hate by avoiding to help the outgroup; (2) People are reluctant to harm the outgroup after being exposed to the opportunity to help it; (3) Groupness-the degree to which people care about their group and its well-being-is related to outgroup hate only when participants encounter the opportunity to harm the outgroup first (before they encounter the opportunity to help it). In this setting the relationship between groupness and outgroup hate spilled over to the subsequent interaction, where it was possible to help the outgroup. When the opportunity to help the outgroup was encountered first, groupness was not related to outgroup hate.

Background - Supply is nowadays higher than the demand, making it possible for consumers to pick, choose and purchase brands that responds to their individual identity. Due to the numerous offerings available, consumers have started to become resistant and they are now withstanding the influence of brands marketing activities. The concept of brand avoidance is one type of personal anti-consumption behaviour which deals with understanding why consumers actively avoid purchasing a specific bran...

This paper analyses Rawls's celebrated difference principle, and its lexicographic extension, in societies with a finite and an infinite number of agents. A unified framework of analysis is set up, which allows one to characterise Rawlsian egalitarian principles by means of a weaker version of a new axiom - the Harm Principle - recently proposed by marven09. This is quite surprising, because the Harm principle is meant to capture a liberal requirement of noninterference and it incorporates no...

Potentially Harmful Therapy and Multicultural Counseling: Bridging Two Disciplinary Discourses

Science.gov (United States)

Wendt, Dennis C.; Gone, Joseph P.; Nagata, Donna K.

2015-01-01

In recent years psychologists have been increasingly concerned about potentially harmful therapy, yet this recent discourse has not addressed issues that have long been voiced by the multicultural counseling and psychotherapy movement. We aim to begin to bring these seemingly disparate discourses of harm into greater conversation with one another, in the service of placing the discipline on a firmer foothold in its considerations of potentially harmful therapy. After reviewing the two discourses and exploring reasons for their divergence, we argue that they operate according to differing assumptions pertaining to the sources, objects, and scope of harm. We then argue that these differences reveal the discipline’s need to better appreciate that harm is a social construct, that psychotherapy may be inherently ethnocentric, and that strategies for collecting evidence of harm should be integrated with a social justice agenda.

Carson, F; Polman, R C J

2010-04-01

Avoidance coping has commonly been reported within literature to be a debilitative process. However, in situations where goal attainment is reduced or eradicated avoidance coping strategies appear to have some benefit. The aim of this study was to identify the role of avoidance coping within the sports injury rehabilitation setting. A mixed methodological approach was utilized with four professional male rugby union players, concurrent with their rehabilitation from anterior cruciate ligament (ACL) surgery. Twice monthly interviews were conducted with each player, along with a self-report diary and the Coping with Health, Injuries and Problems (CHIP; Endler & Parker, 2000) inventory. Content analysis showed six higher-order themes split into two general dimensions: (a) behavioral avoidance coping (physical distraction, social interaction, maladaptive behaviors), and (b) cognitive avoidance coping (denial, thought stopping, cognitive distraction). Results suggest avoidance coping strategies facilitate control of short-term emotional states, as well has appearing to have long-term benefits for injured players. Particular benefits were associated with undertaking alternate work within the sports organization.

Does clinical management improve outcomes following self-harm? Results from the multicentre study of self-harm in England.

Directory of Open Access Journals (Sweden)

Nav Kapur

Full Text Available Evidence to guide clinical management of self-harm is sparse, trials have recruited selected samples, and psychological treatments that are suggested in guidelines may not be available in routine practice.To examine how the management that patients receive in hospital relates to subsequent outcome.We identified episodes of self-harm presenting to three UK centres (Derby, Manchester, Oxford over a 10 year period (2000 to 2009. We used established data collection systems to investigate the relationship between four aspects of management (psychosocial assessment, medical admission, psychiatric admission, referral for specialist mental health follow up and repetition of self-harm within 12 months, adjusted for differences in baseline demographic and clinical characteristics.35,938 individuals presented with self-harm during the study period. In two of the three centres, receiving a psychosocial assessment was associated with a 40% lower risk of repetition, Hazard Ratios (95% CIs: Centre A 0.99 (0.90-1.09; Centre B 0.59 (0.48-0.74; Centre C 0.59 (0.52-0.68. There was little indication that the apparent protective effects were mediated through referral and follow up arrangements. The association between psychosocial assessment and a reduced risk of repetition appeared to be least evident in those from the most deprived areas.These findings add to the growing body of evidence that thorough assessment is central to the management of self-harm, but further work is needed to elucidate the possible mechanisms and explore the effects in different clinical subgroups.

Individuals who self-harm may have an increased risk of aggression toward others, but this association has been insufficiently investigated. More conclusive evidence may affect assessment, treatment interventions, and clinical guidelines. To investigate the association between nonfatal self-harm and violent crime. This population-based longitudinal cohort study, conducted from January 1, 1997, through December 31, 2013, studied all Swedish citizens born between 1982 and 1998 who were 15 years and older (N = 1 850 252). Individuals who emigrated from Sweden before the age of 15 years (n = 104 051) or immigrated to Sweden after the age of 13 years (ie, crime according to the Swedish penal code. The study cohort consisted of 1 850 525 individuals (950 382 males and 900 143 females), and the mean (SD) follow-up time was 8.1 (4.7) years (range, 0-17.0 years; minimum age, 15 years; maximum age, 32 years). During a mean follow-up period of 8.1 years, 55 185 individuals (3.0%) received clinical care for self-harm. The crude hazard ratio was 4.9 (95% CI, 4.8-5.0) for violent crime conviction in exposed individuals compared with the unexposed group. Women who self-harm were at particularly high risk for expressing violent behaviors. After adjustment for relevant psychiatric comorbidities and socioeconomic status, an almost doubled hazard of violent offense remained (hazard ratio, 1.8; 95% CI, 1.8-1.9). Self-harm is associated with an increased risk of conviction for a violent offense in both sexes. The risk of violence, as well as the risk of suicide and self-harm, should be assessed among offending and self-harming individuals.

Harm reduction - a historical view from the left.

Science.gov (United States)

Friedman, S R.; Southwell, M; Bueno, R; Paone, D; Byrne, J; Crofts, N

2001-04-01

The harm reduction movement formed during a period in which social movements of the working class and the excluded were weak, neo-liberalism ideologically triumphant, and potential opposition movements were viewed as offering "tinkering" with the system rather than a total social alternative. This climate shaped and limited the perspectives, strategies, and tactics of harm reductionists almost everywhere. In many countries, this period was also marked by a "political economy of scapegoating" that often targeted drug users as the cause of social woes. This scapegoating took the form of "divide and rule" political initiatives by business and political leaderships to prevent social unrest in a long period of worldwide economic trends toward lowered profit rates and toward increasing income inequality. However, times have changed. Mass strikes and other labor struggles, opposition to the World Trade Organisation and other agencies of neo-liberalism, community-based protests against belt-tightening, and other forms of social unrest have been increasing in many countries. This opens up the possibility of new allies for the harm reduction movement, but also poses difficult problems for which we need to develop answers. On-the-ground experience in alliance formation needs to be combined with careful discussion of and research about what approaches work to convince other movements to work for and with harm reduction, and which approaches do not. Class differences within the harm reduction movement are likely to become more salient in terms of (a) creating internal tensions, (b) increasingly, opening up new ways in which working class harm reductionists can organize within their own communities and workplaces, and (c) producing different strategic orientations that will need to be discussed and debated. As a movement, we will need to find ways to accommodate and discuss differing perspectives, needs, and assessments of opportunities and threats without paralyzing harm

Emergency Department Staff Beliefs About Self-Harm: A Thematic Framework Analysis.

Science.gov (United States)

Koning, Kate Louise; McNaught, Angela; Tuffin, Keith

2017-11-03

To explore the beliefs and attitudes of emergency department staff about self-harm behaviour. Existing studies looking at views regarding self-harm rely solely on the information provided by medical and nursing staff using a questionnaire format. No studies currently consider ancillary staff members' beliefs about self-harm, even though they also work with these patients. A thematic framework analysis of interview transcripts was carried out. Individual semi-structured interviews were conducted from December 2015 to February 2016. Fifteen medical, nursing, and ancillary staff members from a large, tertiary emergency department participated. There were 5 major themes identified-causes of self-harm are multifactorial; beliefs about self-harm can change over time; emergency departments should only focus on the physical; self-harm occurs on a spectrum; and the system has failed. The results suggest participants felt ill-prepared and lacking in appropriate training to help patients that self-harm, and furthermore they have little faith in the mental health system. Staff beliefs and attitudes may change over time with exposure to patients who self-harm, possibly becoming more positive in response to a greater understanding of why the self-harm behaviour is occurring.

Harmful alcohol habits did not explain the social gradient of sickness absence in Swedish women and men

2013-10-01

Full Text Available Background: the aim of this study was to examine the prevalence and socioeconomic distribution of harmful alcohol habits in sick-listed women and men, and whether the social gradient in sickness absence could be explained by the socioeconomic distribution of harmful alcohol habits.Methods: this cross-sectional questionnaire study included newly sick-listed individuals (n=2 798, 19-64 years, 66% women from Sweden. The outcome variable, self-reported harmful alcohol habits, was measured with the Alcohol Use Disorder Identification Test. Registered socioeconomic variables (education, income, occupational class were explanatory variables with age as confounder and selfreported health, symptoms, mental wellbeing, and self-efficacy as mediators. Chi2-tests and logistic regression models were applied.Results: 9% of sick-listed women and 22% of men had harmful alcohol habits. Women with a low annual income (≤149 000 SEK had higher odds ratios (OR=2.47; 95% CI=1.43-4.27 of harmful alcohol habits than those with ≥300 000 SEK/year. The significance of low income remained when mediators were introduced into the logistic regression model (OR=2.03, 95% CI=1.13-3.65. In the model including age, income was no longer significant. Men with low income were more likely to have harmful alcohol habits than men with high income (OR=2.59; 95% CI=1.45-4.62. When mediators were included low income remained significant (OR=2.88; 95% CI=1.56-5.31. Income was no longer significant when age was introduced. Education and occupational status were not significant.Conclusions: harmful alcohol habits were common among sick-listed women and men. The socioeconomic differences in harmful alcohol habits did not explain the social gradient in sickness absence.

Go/no-go discriminated avoidance learning in prenatally x-irradiated rats

Tamaki, Y.; Inouye, M.

1988-01-01

Male Fischer344 rats were exposed to x-irradiation at a dose of 200 rad on Day 17 of gestation. Irradiated and control rats were tested at 10-13 weeks of age with the paradigm of go/no-go (active-passive) discriminated avoidance conditioning for three consecutive daily sessions. During the first conditioning session, they learned only active avoidance responses to two different warning signals. During the second and third sessions, they learned active and passive avoidance responses: in response to one warning signal, rats were required to make an active response to avoid a shock, but not to run in response to the other signal in order to avoid a shock. Prenatally irradiated rats made more active avoidance responses to both warning signals than controls (first session). In the early training phase of the go/no-go task, irradiated rats performed significantly higher active and lower passive avoidance responses than controls. Irradiated rats established a strong tendency to respond actively to the no-go signal, but eventually learned to respond to it

Prison institutional conditions affect risk for self-harm among detainees. In particular, prison overcrowding may increase the likelihood of self-harm by creating competition for resources, space, and enhancing a "deprivation state." The purpose of this paper is to examine the association between overcrowding and prisoner acts of self-harm. This cross-sectional study took place at Geneva's pre-trial prison (capacity:376) between 2006 and 2014. Outcomes were acts of self-harm that required medical attention, and self-strangulation/hanging events (combined into one group, as these are difficult to differentiate). Dichotomous predictors were overcrowding index- annual mean daily population divided by capacity ( > 200 percent vs prison change in gender, area of origin, foreign residency, religion, or psychiatric treatment. The present study is limited by the definition and identification of self-harm. The distinction between self-strangulation and self-hanging, and the precise classification of an intent to die is difficult to make in practice, especially with limited prison data records available. The relevant literature addresses the complexity of the association between non-suicidal and suicidal behavior. Despite this, the combined category self-strangulations/hangings gives some indication of severe self-harm events, especially since the methodology of categorization employed was consistent throughout the entire period of the study. Other limitations include the small sample size and the lack of individual patient data and prison data to help control for confounding factors. Despite these drawbacks, pertinent data (socio-demographics and number of prisoners treated for mental health and drug abuse) remained stable over the years. Thus, there are no apparent changes in the inmate population that could be linked to an increase in self-harm. High-security placements and mean prisoner stay have increased over time, with a decrease in staff to prisoner ratio - and these

Despite accelerating interest in the impact of the internet on suicidal behaviour, empirical work has not captured detailed narratives from those who engaged in suicide-related internet use. This study explored the suicide-related online behaviour of two contrasting samples of distressed users, focusing on their purpose, methods and the main content viewed. In-depth interviews were conducted in the UK between 2014-2016 with i) young people in the community; and ii) self-harm patients presenting to hospital emergency departments. Data were analysed using methods of constant comparison. Suicide-related internet use varied according to the severity of suicidal feelings. In the young people sample, where severity was lower, use was characterised by disorganised browsing without clear purpose. A range of content was 'stumbled upon' including information about suicide methods. They also pursued opportunities to interact with others and explore online help. Self-harm patients were a higher severity group with a history of suicidal behaviour. Their use was purposeful and strategic, focused around 'researching' suicide methods to maximise effectiveness. They made specific choices about content viewed; many consulting factual content in preference to user generated accounts, while help content and communication was avoided. Findings indicate further action is necessary to improve online safety. Also, novel online help approaches are needed to engage individuals experiencing suicidal crisis. Awareness of the nature of suicide-related internet use and how this may reflect the status of an individual's suicidal thinking could be beneficial to clinicians to promote safety and indicate risk.

While the last decade has seen a growth of support for harm reduction around the world, the availability and accessibility of quality harm reduction services in prison settings is uneven and continues to be inadequate compared to the progress achieved in the broader community. This article provides a brief overview of harm reduction in prisons in Catalonia (Spain), Greece, Ireland, Italy, Latvia, Poland, and Portugal. While each country provides a wide range of harm reduction services in the broader community, the majority fail to provide these same services or the same quality of these services, in prison settings, in clear violation of international human rights law and minimum standards on the treatment of prisoners. Where harm reduction services have been available and easily accessible in prison settings for some time, better health outcomes have been observed, including significantly reduced rates of HIV and HCV incidence. While the provision of harm reduction in each of these countries' prisons varies considerably, certain key themes and lessons can be distilled, including around features of an enabling environment for harm reduction, resource allocation, collection of disaggregated data, and accessibility of services.

Self-harm in adolescents is common and repetition rates high. There is limited evidence of the effectiveness of interventions to reduce self-harm. To assess the clinical effectiveness and cost-effectiveness of family therapy (FT) compared with treatment as usual (TAU). A pragmatic, multicentre, individually randomised controlled trial of FT compared with TAU. Participants and therapists were aware of treatment allocation; researchers were blind to allocation. Child and Adolescent Mental Health Services (CAMHS) across three English regions. Young people aged 11-17 years who had self-harmed at least twice presenting to CAMHS following self-harm. Eight hundred and thirty-two participants were randomised to manualised FT delivered by trained and supervised family therapists ( n  = 415) or to usual care offered by local CAMHS following self-harm ( n  = 417). Rates of repetition of self-harm leading to hospital attendance 18 months after randomisation. Out of 832 young people, 212 (26.6%) experienced a primary outcome event: 118 out of 415 (28.4%) randomised to FT and 103 out of 417 (24.7%) randomised to TAU. There was no evidence of a statistically significant difference in repetition rates between groups (the hazard ratio for FT compared with TAU was 1.14, 95% confidence interval 0.87 to 1.49; p  = 0.3349). FT was not found to be cost-effective when compared with TAU in the base case and most sensitivity analyses. FT was dominated (less effective and more expensive) in the complete case. However, when young people's and caregivers' quality-adjusted life-year gains were combined, FT incurred higher costs and resulted in better health outcomes than TAU within the National Institute for Health and Care Excellence cost-effectiveness range. Significant interactions with treatment, indicating moderation, were detected for the unemotional subscale on the young person-reported Inventory of Callous-Unemotional Traits ( p  = 0.0104) and the affective involvement

Grouping is a common phenomenon in pedestrian crowds and group modeling is still an open challenging problem. When grouping pedestrians avoid each other, different patterns can be observed. Pedestrians can keep close with group members and avoid other groups in cluster. Also, they can avoid other groups separately. Considering this randomness in avoidance patterns, we propose a collision avoidance model for two-pedestrian groups. In our model, the avoidance model is proposed based on velocity obstacle method at first. Then grouping model is established using Distance constrained line (DCL), by transforming DCL into the framework of velocity obstacle, the avoidance model and grouping model are successfully put into one unified calculation structure. Within this structure, an algorithm is developed to solve the problem when solutions of the two models conflict with each other. Two groups of bidirectional pedestrian experiments are designed to verify the model. The accuracy of avoidance behavior and grouping behavior is validated in the microscopic level, while the lane formation phenomenon and fundamental diagrams is validated in the macroscopic level. The experiments results show our model is convincing and has a good expansibility to describe three or more pedestrian groups.

Harm Experienced from the Heavy Drinking of Family and Friends in the General Population: A Comparative Study of Six Northern European Countries

Full Text Available Background Epidemiological research on alcohol-related harm has long given priority to studies on harm to the drinker. A limitation with this perspective is that it neglects the harm drinking causes to people around the drinker, and thus, it fails to give a full picture of alcohol-related harm in society. Aim The aim was to compare the prevalence and correlates of experiencing harm from the heavy drinking by family and friends across the Nordic countries and Scotland and to discuss whether potential differences match levels of drinking, prevalence of binge drinking, and alcohol-related mortality. Data and Method Data from recent national general population surveys with similar questions on experiences of harms from the drinking of family and friends were collected from Sweden, Finland, Denmark, Norway, Iceland, and Scotland. Results National estimates of the overall population prevalence of harm from the drinking of family and friends ranged from 14% to 28% across these countries, with the highest prevalence in Finland, Iceland, and Norway and lower estimates for Denmark, Sweden, and Scotland. Across all countries, the prevalence of harm from heavy drinking by family and friends was significantly higher among women and young respondents. Conclusion This study revealed large differences in the prevalence of harm across the study countries, as well as by gender and age, but the differences do not match the variation in population drinking and other indicators of harm. The implications of the findings for future research are discussed.

Gender roles, suicidal ideation, and self-harming in young adults.

This study investigates whether positive and negative conventional gender roles relate to suicidal ideation and self-harming in different ways among young adults. Participants completed an online survey about previous self-harm, recent suicidal ideation, and positive and negative aspects of conventional masculinity and femininity. Logistic regression analyses showed that negative femininity positively predicted self-harm and recent suicidal ideation status. Positive femininity was unrelated. Positive masculinity was negatively related to suicidal ideation and self-harming while negative masculinity was negatively related to self-harming only. The findings suggest that it is not the conventional feminine gender role per se that is associated with suicidality but specific negatively evaluated aspects. Conceptualizing gender as a multivariate construct may be useful in the gender socialization theory of suicidal behavior.

To examine the perspectives of people aged 80 years or older who self-harmed regarding their reasons for self-harm and its consequences, and their perceptions of care. A qualitative study using in-depth interviews. Participants were recruited from two teaching hospitals and associated community services. People aged 80 years or older who had self-harmed within the previous month. Structured psychiatric assessment including cognitive testing, DSM-5 diagnosis, and an in-depth qualitative interview focusing upon the reasons for and consequences of self-harm. Narrative enquiry was used to guide the discussion. All interviews were undertaken by a geriatric psychiatrist, audio recorded, transcribed verbatim, and subjected to thematic analysis using N-VIVO. Themes that emerged for the reasons for self-harm included "enough is enough"; "loneliness"; "disintegration of self"; "being a burden"; "cumulative adversity"; "hopelessness and endless suffering"; "helplessness with rejection"; and "the untenable situation". Themes for the consequences of self-harm were "becoming engaged with or distanced from family"; "the problem was solved"; "gaining control"; "I"m worse off now"; "rejection by health professionals"; and "tension in the role of the inpatient clinical environment". Self-harm may communicate a need that cannot otherwise be expressed. An individualized person-centered approach is required to respond to self-harm, including a combination of practical, medical, and psychological approaches as indicated. Involvement of families in the process of understanding the meaning of and responding to self-harm through education and family therapy, as well as education of healthcare professionals beyond risk factor notation may be indicated.

Preserving human potential as freedom: a framework for regulating epigenetic harms.

Science.gov (United States)

Khan, Fazal

2010-01-01

Epigenetics is a rapidly evolving scientific field of inquiry examining how a wide range of environmental, social, and nutritional exposures can dramatically control how genes are expressed without changing the underlying DNA. Research has demonstrated that epigenetics plays a large role in human development and in disease causation. In a sense, epigenetics blurs the distinction between "nature" and "nurture" as experiences (nurture) become a part of intrinsic biology (nature). Remarkably, some epigenetic modifications are durable across generations, meaning that exposures from our grandparents' generation might affect our health now, even if we have not experienced the same exposures. In the same vein, current exposures could affect the health of not only individuals currently living but also future generations. Given the relative novelty of epigenetics research and the multifactorial nature of human development and disease causation, it is unlikely that conclusive proof can be established showing that particular exposures lead to epigenetic risks that manifest into specific conditions. Using the Capabilities Approach ("CA") developed by Amartya Sen and Martha Nussbaum, this article argues that epigenetic risk is not merely a medical issue, but that it more generally implicates the underlying fairness and justice of our social contract. For instance, how we develop mentally or physically has a tremendous impact upon our inherent capabilities and our set of life options. The CA prompts us to ask questions such as: (1) what impact do particular epigenetic risks have on our ability to exercise free choices; (2) are these risks avoidable; and (3) how are these risks distributed across society? Due to the complex nature of epigenetic risk, tort law is predictably incapable of addressing this harm. Further, while regulatory agencies possess the statutory authority to begin addressing epigenetic harms, currently these agencies are not attuned to measure or to respond to

Tobacco harm reduction: an alternative cessation strategy for inveterate smokers

Directory of Open Access Journals (Sweden)

Godshall William T

2006-12-01

Full Text Available Abstract According to the Centers for Disease Control and Prevention, about 45 million Americans continue to smoke, even after one of the most intense public health campaigns in history, now over 40 years old. Each year some 438,000 smokers die from smoking-related diseases, including lung and other cancers, cardiovascular disorders and pulmonary diseases. Many smokers are unable – or at least unwilling – to achieve cessation through complete nicotine and tobacco abstinence; they continue smoking despite the very real and obvious adverse health consequences. Conventional smoking cessation policies and programs generally present smokers with two unpleasant alternatives: quit, or die. A third approach to smoking cessation, tobacco harm reduction, involves the use of alternative sources of nicotine, including modern smokeless tobacco products. A substantial body of research, much of it produced over the past decade, establishes the scientific and medical foundation for tobacco harm reduction using smokeless tobacco products. This report provides a description of traditional and modern smokeless tobacco products, and of the prevalence of their use in the United States and Sweden. It reviews the epidemiologic evidence for low health risks associated with smokeless use, both in absolute terms and in comparison to the much higher risks of smoking. The report also describes evidence that smokeless tobacco has served as an effective substitute for cigarettes among Swedish men, who consequently have among the lowest smoking-related mortality rates in the developed world. The report documents the fact that extensive misinformation about ST products is widely available from ostensibly reputable sources, including governmental health agencies and major health organizations. The American Council on Science and Health believes that strong support of tobacco harm reduction is fully consistent with its mission to promote sound science in regulation and in

‘Abstract Endangerment’, Two Harm Principles, and Two Routes to Criminalisation

Directory of Open Access Journals (Sweden)

R.A. Duff

2015-12-01

Full Text Available We need to distinguish, as theorists too often fail to distinguish, two distinct harm principles. One, the Harmful Conduct Principle, concerns the criminalisation of conduct that is itself harmful or dangerous: that principle cannot explain how we can have good reason to create offences of so-called ‘abstract endangerment’, of which many road traffic offences are good examples. We can explain such offences as those by appeal to a different harm principle, the Harm Prevention Principle. That principle, however, is a principle not of criminalisation, but of regulation: it gives us reason to regulate conduct if doing so will efficiently prevent harm, without imposing undue burdens on those whose conduct is regulated. We then have reason to criminalise violations of such regulations, not because such violations are always harmful, but if and because they are wrongful. This distinction, between two kinds of principle and two possible routes towards criminalisation, can be drawn whatever goals or values we posit as our starting points.

Nagao, Mitsuyoshi; Suto, Kazuhiro; Ohuchi, Azuma

2010-04-01

When large scale earthquake occurred, the word of "harmful rumor" came to be frequently heard. The harmful rumor means an economic damage which is caused by the action that people regard actually safe foods or areas as dangerous and then abort consumption or sightseeing. In the case of harmful rumor caused by earthquake, especially, tourism industry receives massive economic damage. Currently, harmful rumor which gives substantial economic damage have become serious social issue which must be solved. In this paper, we propose a countermeasure method for harmful rumor on the basis of media trend in order to implement speedy recovery from harmful rumor. Here, we investigate the amount and content of information which is transmitted to the general public by the media when an earthquake occurred. In addition, the media information in three earthquakes is treated as instance. Finally, we discuss an effective countermeasure method for dispeling harmful rumor through these analysis results.

The Theory of Dyadic Morality: Reinventing Moral Judgment by Redefining Harm.

Science.gov (United States)

Schein, Chelsea; Gray, Kurt

2018-02-01

The nature of harm-and therefore moral judgment-may be misunderstood. Rather than an objective matter of reason, we argue that harm should be redefined as an intuitively perceived continuum. This redefinition provides a new understanding of moral content and mechanism-the constructionist Theory of Dyadic Morality (TDM). TDM suggests that acts are condemned proportional to three elements: norm violations, negative affect, and-importantly-perceived harm. This harm is dyadic, involving an intentional agent causing damage to a vulnerable patient (A→P). TDM predicts causal links both from harm to immorality (dyadic comparison) and from immorality to harm (dyadic completion). Together, these two processes make the "dyadic loop," explaining moral acquisition and polarization. TDM argues against intuitive harmless wrongs and modular "foundations," but embraces moral pluralism through varieties of values and the flexibility of perceived harm. Dyadic morality impacts understandings of moral character, moral emotion, and political/cultural differences, and provides research guidelines for moral psychology.

Gambling Harm and Crime Careers.

Incarcerated populations across the world have been found to be consistently and significantly more vulnerable to problem gambling than general populations in the same countries. In an effort to gain a more specific understanding of this vulnerability the present study applied latent class analysis and criminal career theory to gambling data collected from a sample of English and Scottish, male and female prisoners (N = 1057). Theoretical links between gambling and crime were tested through three hypotheses: (1) that prisoners in the UK would have higher rates of problem gambling behaviour than the national population; (2) that if the link between gambling and crime is coincidental, gambling behaviour would be highly prevalent in an offending population, and (3) if connections between gambling behaviour and offending are co-symptomatic a mediating factor would show a strong association. The first of these was supported, the second was not supported and the third was partially supported. Latent class analysis found six gambling behaviour clusters measured by responses to the Problem Gambling Severity Index, primarily distinguished by loss chasing behaviour. Longitudinal offending data drawn from the Police National Computer database found four criminal career types, distinguished by frequency and persistence over time. A significant association was found between higher level loss chasing and high rate offending in criminal careers suggesting that impulse control may be a mediating factor for both gambling harm and criminal careers.

2011-01-01

Objective To assess factors associated with drug-related harms related to policing among injection drug users (IDUs) in Tijuana, Mexico. Methods IDUs who were over 18 years old and had injected drugs within the last six months were recruited via respondent-driven sampling and underwent questionnaires and testing for HIV (human immunodeficiency virus), syphilis and TB (tuberculosis). Random effects logistic regression was used to simultaneously model factors associated with five drug-related harms related to policing practices in the prior six months (i.e., police led them to rush injections; affected where they bought drugs; affected locations where they used drugs; feared that police will interfere with their drug use; receptive syringe sharing). Results Of 727 IDUs, 85% were male; median age was 38 years. Within the last 6 months, 231 (32%) of IDUs reported that police had led them to rush injections, affected where they bought or used drugs or were very afraid police would interfere with their drug use, or shared syringes. Factors independently associated with drug-related harms related to policing within the last six months included: recent arrest, homelessness, higher frequencies of drug injection, use of methamphetamine, using the local needle exchange program and perceiving a decrease in the purity of at least one drug. Conclusions IDUs who experienced drug-related harms related to policing were those who were most affected by other micro and macro influences in the physical risk environment. Police education programs are needed to ensure that policing practices do not exacerbate risky behaviors or discourage protective behaviors such as needle exchange program use, which undermines the right to health for people who inject drugs.

Full Text Available The coal mining has brought a series of ecological problems and environmental problems in permafrost regions. Taking Muli coal-mining area as an example, this article attempts to analyse the environmental harms caused by coal mining and its protection measures in permafrost regions of Qinghai–Tibet Plateau. This article analyses the influence of open mining on the surrounding permafrost around the open pit by using the numerical simulation. The results show that (1 based on the interrelation between coal mining and permafrost environment, these main environmental harm include the permafrost change and the natural environment change in cold regions; (2 once the surface temperature rises due to open mining, the permafrost will disappear with the increase of exploitation life. If considering the solar radiation, the climate conditions and the geological condition around the pit edge, the maximum thaw depth will be more than 2 m; (3 the protection measures are proposed to avoid the disadvantage impact on the permafrost environment caused by coal mining. It will provide a scientific basis for the resource development and environment protection in cold regions.

S. RAGONESE

2009-06-01

Full Text Available The Mediterranean hake Merluccius merluccius L., 1758, is the emblem of the so-called Mediterranean demersal fisheries paradox, showing a persistent, although stable, status of growth overexploitation and an impressive gap between current and any biological reference point. Almost full avoidance capability of large size females to bottom trawls, higher overall growth rates than previously believed and higher natural mortality in juveniles than adult, were considered among the most plausible explanation factors of such persistence. In the present note, arguments are illustrated to raise some concern about avoidance and highlight the important role of the other factors in improving assessments and launching a short term recovery plan for Mediterranean Hake stocks which is more acceptable to fishermen.

Much debate surrounds the potential effects of self-harm forum use. Arguments in favor highlight factors such as providing access to a supportive community. However critical voice highlighting potential dangers such as forums serving as a platform to promote self-harm, clearly dominate the debate. Using an online questionnaire, the goal of the current study was to examine sociodemographic characteristics, the psychopathology of forum users, motives for participating, and subjective effects of self-harm forum use. A total of 309 self-harm forum users participated in this study. 3 heterogeneous user types with differing motives for visiting the forum and different usage effects were identified. The results question the assumptions that self-harm forums are a source of harm and point to their predominantly constructive and preventive functions.

There is a gap in understanding the meaning and motives behind suicidal behaviour. Using the Ideal Type methodology, Jean Baechler systematically examined the internal logic of suicidal and self-harming behaviours. He developed a typology of eleven typical meanings/motives: Flight, Grief, Self-punishment, Vengeance, Crime, Blackmail, Appeal, Sacrifice, Transfiguration, Ordeal and Game. To develop and validate a standardized instrument to measure the motives/meanings of suicidal and self-harming behaviours, using Baechler's typology. We developed a self-fill Likert questionnaire (Ideal Typical Meaning Questionnaire, ITMQ) covering ten of Baechler's eleven types. The questionnaire was completed by 147 patients within four weeks of attempting suicide or self-harm. The Death Attitude Profile-Revised (DAP-R) questionnaire was used to examine the concurrent validity of the Flight and the Transfiguration types and to explore the association between suicidal/self-harming motives and views about death. The final 25-item ITMQ has an eight-factor structure (Appeal/Blackmail, Ordeal/Game, Vengeance, Self-punishment, Sacrifice, Flight, Grief and Transfiguration) supporting Baechler's theory. The types have adequate reliability. Correlations with the DAP-R gave some support for the concurrent validity of the Flight and Transfiguration types. The ITMQ is a measure of suicidal and self-harming motives/meanings based on a sound conceptual framework and could significantly contribute to the understanding of suicidal and self-harming behaviour in research and clinical settings.

Intoxication with alcohol at the time of self-harm and pre-existing involvement with mental health services are associated with a pre-disposition to repetition of self-harming behavior in a large cohort of older New Zealanders presenting with an index episode of self-harm.

The paper on predictors of repeat self-harm and suicide by Cheung et al. (2017), which has been chosen by the editorial team as paper of the month for this issue of International Psychogeriatrics, makes a very useful contribution to the study of self-harm and suicide in late life. Of 339 individuals presenting with an index episode of self-harm to one of seven Emergency Departments (EDs) in New Zealand, close to 15% harmed themselves again within one year and for nearly one in six of these 50 people, the repeat episode was fatal. Having alcohol in the blood and already being engaged with mental health services at the time of the index episode both had some utility in predicting the occurrence of a further self-harm episode. While it is encouraging that mental health services look to have been focusing on those who turned out to be at highest risk, clinicians may need to be particularly vigilant when following up individuals who had been drinking alcohol at the time of an initial self-harm presentation. This study also emphasizes the high risk of recurrent self-harm and completed suicide in those older adults who harm themselves and survive the initial episode. It deserves to be widely cited and gives some direction for future research on interventions designed to diminish the recurrence of self-harm in those of our patients who have presented to an ED with an initial self-harm episode.

Water avoidance stress is a potent psychological stressor and it is associated with visceral hyperalgesia, which shows degeneration of the urothelial layer mimicking interstitial cystitis. Cyclooxygenase-2 inhibitors have been recognized to ameliorate frequency both in clinical and experimental settings. We investigated the voiding pattern and cyclooxygenase-2 expression in a rat bladder model of water avoidance stress. After being subjected to water avoidance stress or a sham procedure, rats underwent metabolic cage analysis and cystometrography. Real time reverse transcription polymerase chain reaction was carried out to examine cyclooxygenase-2 messenger ribonucleic acid in bladders of rats. Protein expression of cyclooxygenase-2 was analyzed with immunohistochemistry and western blotting. Furthermore, the effects of the cyclooxygenase-2 inhibitor, etodolac, were investigated by carrying out cystometrography, immunohistochemistry and western blotting. Metabolic cage analysis and cystometrography showed significantly shorter intervals and less volume of voiding in water avoidance stress rats. Significantly higher expression of cyclooxygenase-2 messenger ribonucleic acid was verified by reverse transcription polymerase chain reaction. Immunohistochemistry and western blotting showed significantly higher cyclooxygenase-2 protein levels in water avoidance stress bladders. Furthermore, immunohistochemistry showed high cyclooxygenase-2 expression exclusively in smooth muscle cells. All water avoidance stress-induced changes were reduced by cyclooxygenase-2 inhibitor pretreatment. Chronic stress might cause frequency through cyclooxygenase-2 gene upregulation in bladder smooth muscle cells. Further study of cyclooxygenase-2 in the water avoidance stress bladder might provide novel therapeutic modalities for interstitial cystitis. © 2011 The Japanese Urological Association.

Minimising the harm from nicotine use: finding the right regulatory framework.

Science.gov (United States)

Borland, Ron

2013-05-01

The tobacco problem can be usefully conceptualised as two problems: eliminating the most harmful forms of nicotine use (certainly cigarettes, and probably all smoked tobacco), and minimising the use and/or harms from use of lower-harm, but addictive forms of nicotine. A possible target would be to effectively eliminate use of the most harmful forms of nicotine within the next decade and then turn our focus to a long-term strategy for the low-harm forms. This paper focuses on the administrative framework(s) needed to accomplish these twin tasks. For a phase-out taking a long time and/or for dealing with residually net harmful and addictive products, there are severe limitations to allowing for-profit marketing of tobacco because such an arrangement (the current one in most countries) can markedly slow down progress and because of the difficulty of constraining marketing in ways that minimise undesirable use. A harm reduction model where the marketing is under the control of a non-profit entity (a regulated market) is required to curtail the incredible power of for-profit marketing and to allow tobacco marketing to be done in ways that further the goal of minimising tobacco-related harm. Countries with a nationalised industry can move their industry onto a harm minimisation framework if they have the political will. Countries with a for-profit industry should consider whether the time and effort required to reconstruct the market may, in the longer term, facilitate achieving their policy goals.

Harm reduction psychotherapy: extending the reach of traditional substance use treatment.

Science.gov (United States)

Tatarsky, Andrew

2003-12-01

Harm reduction is a paradigm-shifting idea that has the potential to significantly improve the treatment of problem substance users. The essence of harm reduction is the recognition that treatment must start from the client's needs and personal goals and that all change that reduces the harms associated with substance use can be regarded as valuable. The paper presents harm reduction's rationale, principles, treatment implications, and application to psychotherapy. The author describes his model of Integrative Harm Reduction Psychotherapy, an approach that integrates a strategic skills-building focus with an exploration of the multiple meanings of substance use and the importance of the therapeutic alliance.

Provoked vestibulodynia (PVD) is a prevalent vulvovaginal pain condition that is triggered primarily during sexual intercourse. PVD adversely impacts women's and their partners' sexual relationship and psychological well-being. Over 80% of women with PVD continue to have intercourse, possibly because of sexual goals that include wanting to pursue desirable outcomes (i.e., approach goals; such as a desire to maintain intimacy) and avoid negative outcomes (i.e., avoidance goals; such as avoiding a partner's disappointment). The aim of this study was to investigate associations between approach and avoidance sexual goals and women's pain, as well as the sexual, relational, and psychological well-being of affected couples. Women with PVD (N = 107) and their partners completed measures of sexual goals, sexual satisfaction, relationship satisfaction, and depression. Women also completed measures of pain during intercourse and sexual functioning. (1) Global Measure of Sexual Satisfaction Scale, (2) Dyadic Adjustment Scale-Revised or the Couple Satisfaction Index, (3) Beck Depression Inventory-II, (4) numerical rating scale of pain during intercourse, and (5) Female Sexual Function Index. When women reported higher avoidance sexual goals, they reported lower sexual and relationship satisfaction, and higher levels of depressive symptoms. In addition, when partners of women reported higher avoidance sexual goals, they reported lower relationship satisfaction. When women reported higher approach sexual goals, they also reported higher sexual and relationship satisfaction. Targeting approach and avoidance sexual goals could enhance the quality and efficacy of psychological couple interventions for women with PVD and their partners. © 2015 International Society for Sexual Medicine.

Environments, risk and health harms: a qualitative investigation into the illicit use of anabolic steroids among people using harm reduction services in the UK.

Kimergård, Andreas; McVeigh, Jim

2014-06-04

The illicit use of anabolic steroids among the gym population continues to rise, along with the number of steroid using clients attending harm reduction services in the UK. This presents serious challenges to public health. Study objectives were to account for the experiences of anabolic steroid users and investigate how 'risk environments' produce harm. Qualitative face-to-face interviews with 24 users of anabolic steroids engaged with harm reduction services in the UK. Body satisfaction was an important factor when deciding to start the use of anabolic steroids. Many users were unaware of the potential dangers of using drugs from the illicit market, whereas some had adopted a range of strategies to negotiate the hazards relating to the use of adulterated products, including self-experimentation to gauge the perceived efficacy and unwanted effects of these drugs. Viewpoints, first-hand anecdotes, norms and practices among groups of steroid users created boundaries of 'sensible' drug use, but also promoted practices that may increase the chance of harms occurring. Established users encouraged young users to go to harm reduction services but, at the same time, promoted risky injecting practices in the belief that this would enhance the efficacy of anabolic steroids. Current steroid-related viewpoints and practices contribute to the risk environment surrounding the use of these drugs and may undermine the goal of current public health strategies including harm reduction interventions. The level of harms among anabolic steroid users are determined by multiple and intertwining factors, in addition to the harms caused by the pharmacological action or injury and illness associated with incorrect injecting techniques.

Hydroclimatic conditions trigger record harmful algal bloom in western Patagonia (summer 2016).

2018-01-22

A harmful algal bloom (HAB) of the raphidophyta alga Pseudochattonella cf. verruculosa during the 2016 austral summer (February-March) killed nearly 12% of the Chilean salmon production, causing the worst mass mortality of fish and shellfish ever recorded in the coastal waters of western Patagonia. The HAB coincided with a strong El Niño event and the positive phase of the Southern Annular Mode that altered the atmospheric circulation in southern South America and the adjacent Pacific Ocean. This led to very dry conditions and higher than normal solar radiation reaching the surface. Using time series of atmospheric, hydrologic and oceanographic data we show here that an increase in surface water temperature and reduced freshwater input resulted in a weakening of the vertical stratification in the fjords and sounds of this region. This allowed the advection of more saline and nutrient-rich waters, ultimately resulting in an active harmful algal bloom in coastal southern Chile.

To (1) estimate the lifetime and 12-month prevalence of self-harm without suicide intent in young people aged 12-17 years, (2) describe the co-morbidity of these behaviours with mental illness and (3) describe their co-variation with key social and demographic variables. A nationally representative random sample of households with children aged 4-17 years recruited in 2013-2014. The survey response rate was 55% with 6310 parents and carers of eligible households participating. In addition, 2967 (89%) of young people aged 11-17 completed a self-report questionnaire with 2653 of the 12- to 17-year-olds completing questions about self-harm behaviour. In any 12-month period, about 8% of all 12- to 17-year-olds (an estimated 137,000 12- to 17-year-olds) report engaging in self-harming behaviour without suicide intent. This prevalence increases with age to 11.6% in 16- to 17-year-olds. Eighteen percent (18.8%; 95% confidence interval [CI] = [14.5, 23.0]) of all 12- to 17-year-old young people with any mental health disorder measured by parent or carer report said that they had engaged in self-harm in the past 12 months. Among young people who were measured by self-report and met criteria for the Diagnostic and Statistical Manual of Mental Disorders' major depressive disorder almost half (46.6%; 95% CI = [40.0, 53.1]) also reported that they had engaged in self-harm in the past 12 months. Suicide risk among those who self-harm is significantly elevated relative to the general population. The demonstrated higher risks in these young people for continued harm or possible death support the need for ongoing initiatives to reduce self-harm through mental health promotion, improved mental health literacy and continuing mental health reform to ensure services are accessible to, and meet the needs of families and young persons. © The Royal Australian and New Zealand College of Psychiatrists 2015.

Harm reduction and law enforcement in Vietnam: influences on street policing

2012-01-01

Background and rationale The HIV epidemic in Vietnam has from its start been concentrated among injecting drug users. Vietnam instituted the 2006 HIV/AIDS Law which includes comprehensive harm reduction measures, but these are unevenly accepted and inadequately implemented. Ward police are a major determinant of risk for IDUs, required to participate in drug control practices (especially meeting quotas for detention centres) which impede support for harm reduction. We studied influences on ward level police regarding harm reduction in Hanoi to learn how to better target education and structural change. Methods After document review, we interviewed informants from government, NGOs, INGOs, multilateral agencies, and police, using semi-structured guides. Topics covered included perceptions of harm reduction and the police role in drug law enforcement, and harm reduction training and advocacy among police. Results Police perceive conflicting responsibilities, but overwhelmingly see their responsibility as enforcing drug laws, identifying and knowing drug users, and selecting those for compulsory detention. Harm reduction training was very patchy, ward police not being seen as important to it; and understanding of harm reduction was limited, tending to reflect drug control priorities. Justification for methadone was as much crime prevention as HIV prevention. Competing pressures on ward police create much anxiety, with performance measures based around drug control; recourse to detention resolves competing pressures more safely. There is much recognition of the importance of discretion, and much use of it to maintain good social order. Policy dissemination approaches within the law enforcement sector were inconsistent, with little communication about harm reduction programs or approaches, and an unfounded assumption that training at senior levels would naturally reach to the street.

Objective: To understand the current status of dust and/or harmful gas exposure in adults aged ≥40 years and corresponding protection in China, and provide evidence for strengthening the occupational protection against dust and harmful gas exposure. Methods: The data were obtained from 2014-2015 COPD surveillance in China. A total of 75 107 adults aged ≥40 years selected through multi-stage stratified cluster sampling from 125 surveillance points in 31 provinces (autonomous regions and municipalities) were surveyed in face to face interviews. Occupational exposure was defined as occupational exposure to dust and/or harmful gas for more than 1 year. The weighted percentages of exposure were estimated by using complex sampling design. Results: Among eligible 71 061 participants, the exposure rate of dust and/or harmful gas was 46.3 % . The exposure rate in rural area (51.7 % ) was significantly higher than that in urban area (40.3 % ), and the exposure rate in the western area was higher than those in the eastern and central areas ( P school and below was highest (49.7 % , P protection rate was 26.7 % , and the exposure protection rate was highest in the eastern area (29.9 % ), followed by that in the central area (27.0 % ) and that in the western area (22.9 % ) The exposure protection rate in urban area was significantly higher than that in rural area, and the exposure protection rate was lowest in those with education level of primary school and below. The regular exposure protection was taken by only 50.7 % of the adults surveyed. Conclusion: The exposure rate of dust and/or harmful gas is high in China, while the exposure protection rate is very low. Health education, occupational protection and supervision should be strengthened among those with low education level, and those living in rural area and in the western area.

Doing better (or worse) than one's parents: Social status, mobility, and performance-avoidance goals.

Jury, Mickaël; Bruno, Alisée; Darnon, Céline

2018-01-11

Previous research has shown that, when succeeding in higher education, first-generation (FG) students endorse more performance-avoidance goals (i.e., the fear of performing poorly) than continuing-generation (CG) students. In this study, individual mobility is examined as a predictor of performance-avoidance goal endorsement. It is argued that FG students endorse more these goals than CG students because in higher education, the former (but not the latter) experience upward mobility. In addition, CG can also be at risk of endorsing these goals when they are confronted with downward mobility. Two studies were conducted with psychology students (N = 143 in Study 1; N = 176 in Study 2). In Study 1, FG and CG students' perceived upward mobility was measured. In Study 2, FG and CG students were provided with a feedback that suggested either upward or downward mobility. In both studies, participants reported their level of performance-avoidance goal endorsement. Results from Study 1 supported an indirect effect of status on performance-avoidance goals via a higher perception of upward mobility. Results from Study 2 supported that psychology students who face mobility (i.e., FG students who received better feedback than their usual level of performance, CG students who received worse feedback than their usual level of performance) increased their performance-avoidance goals the most. Taken together, the results of these studies support that one's actual social position and, even more, the social position one is about to reach are reliable predictors of performance-avoidance goals. © 2018 The British Psychological Society.

Stenling, Andreas; Hassmén, Peter; Holmström, Stefan

2014-01-01

People's implicit beliefs of ability have been suggested as an antecedent of achievement goal adoption, which has in turn been associated with behavioural, cognitive and affective outcomes. This study examined a conditional process model with team sport athletes' approach-avoidance achievement goals as mediators between their implicit beliefs of sport ability and sport-related cognitive anxiety. We expected gender to moderate the paths from implicit beliefs of ability to approach-avoidance goals and from approach-avoidance goals to cognitive anxiety. Team sport athletes with a mean age of 20 years (163 females and 152 males) responded to questionnaires about their implicit beliefs of sport ability, approach-avoidance goals and sport-related cognitive anxiety. Incremental beliefs, gender and the interaction between them predicted mastery-approach goals. Gender also predicted mastery-avoidance goals, with females reporting higher levels than males. Mastery-avoidance goals, gender and the interaction between them predicted cognitive anxiety, with females reporting higher levels of anxiety than males. Entity beliefs positively predicted performance-avoidance goals and the interaction between performance-approach and gender predicted anxiety. The indirect effects also showed gender differences in relation to performance-approach goals. Taken together, our results suggest that coaches trying to create a facilitating climate for their male and female athletes may be wise to consider their athletes' anxiety and achievement goal patterns as these may affect both the athletes' well-being and performance.

Cost-effectiveness and harm-benefit analyses of risk-based screening strategies for breast cancer.

Directory of Open Access Journals (Sweden)

Ester Vilaprinyo

Full Text Available The one-size-fits-all paradigm in organized screening of breast cancer is shifting towards a personalized approach. The present study has two objectives: 1 To perform an economic evaluation and to assess the harm-benefit ratios of screening strategies that vary in their intensity and interval ages based on breast cancer risk; and 2 To estimate the gain in terms of cost and harm reductions using risk-based screening with respect to the usual practice. We used a probabilistic model and input data from Spanish population registries and screening programs, as well as from clinical studies, to estimate the benefit, harm, and costs over time of 2,624 screening strategies, uniform or risk-based. We defined four risk groups, low, moderate-low, moderate-high and high, based on breast density, family history of breast cancer and personal history of breast biopsy. The risk-based strategies were obtained combining the exam periodicity (annual, biennial, triennial and quinquennial, the starting ages (40, 45 and 50 years and the ending ages (69 and 74 years in the four risk groups. Incremental cost-effectiveness and harm-benefit ratios were used to select the optimal strategies. Compared to risk-based strategies, the uniform ones result in a much lower benefit for a specific cost. Reductions close to 10% in costs and higher than 20% in false-positive results and overdiagnosed cases were obtained for risk-based strategies. Optimal screening is characterized by quinquennial or triennial periodicities for the low or moderate risk-groups and annual periodicity for the high-risk group. Risk-based strategies can reduce harm and costs. It is necessary to develop accurate measures of individual risk and to work on how to implement risk-based screening strategies.

Application of Decision Tree on Collision Avoidance System Design and Verification for Quadcopter

Chen, C.-W.; Hsieh, P.-H.; Lai, W.-H.

2017-08-01

The purpose of the research is to build a collision avoidance system with decision tree algorithm used for quadcopters. While the ultrasonic range finder judges the distance is in collision avoidance interval, the access will be replaced from operator to the system to control the altitude of the UAV. According to the former experiences on operating quadcopters, we can obtain the appropriate pitch angle. The UAS implement the following three motions to avoid collisions. Case1: initial slow avoidance stage, Case2: slow avoidance stage and Case3: Rapid avoidance stage. Then the training data of collision avoidance test will be transmitted to the ground station via wireless transmission module to further analysis. The entire decision tree algorithm of collision avoidance system, transmission data, and ground station have been verified in some flight tests. In the flight test, the quadcopter can implement avoidance motion in real-time and move away from obstacles steadily. In the avoidance area, the authority of the collision avoidance system is higher than the operator and implements the avoidance process. The quadcopter can successfully fly away from the obstacles in 1.92 meter per second and the minimum distance between the quadcopter and the obstacle is 1.05 meters.

Full Text Available The purpose of the research is to build a collision avoidance system with decision tree algorithm used for quadcopters. While the ultrasonic range finder judges the distance is in collision avoidance interval, the access will be replaced from operator to the system to control the altitude of the UAV. According to the former experiences on operating quadcopters, we can obtain the appropriate pitch angle. The UAS implement the following three motions to avoid collisions. Case1: initial slow avoidance stage, Case2: slow avoidance stage and Case3: Rapid avoidance stage. Then the training data of collision avoidance test will be transmitted to the ground station via wireless transmission module to further analysis. The entire decision tree algorithm of collision avoidance system, transmission data, and ground station have been verified in some flight tests. In the flight test, the quadcopter can implement avoidance motion in real-time and move away from obstacles steadily. In the avoidance area, the authority of the collision avoidance system is higher than the operator and implements the avoidance process. The quadcopter can successfully fly away from the obstacles in 1.92 meter per second and the minimum distance between the quadcopter and the obstacle is 1.05 meters.

Full Text Available Jiri Koutek, Jana Kocourkova, Iva Dudova Department of Child Psychiatry, Charles University Second Faculty of Medicine, University Hospital Motol, Prague, Czech Republic Abstract: Comorbid psychopathology, including self-harm and suicidal behavior, is often found in patients with eating disorders. To better understand the reasons for high comorbid psychopathology among eating disorders, self-harm, and suicidal behavior, we examined this comorbidity in female patients hospitalized with eating disorders. In a sample of 47 girls admitted for anorexia nervosa, atypical anorexia nervosa, and bulimia nervosa, 72% had depressive symptoms, 11% had obsessive-compulsive symptoms, 9% had anxiety disorder, 23% had substance abuse, and 57% had disharmonious personality development. Suicidal behavior was present in 60% of patients and self-harm in 49%. Association was found between self-harm and suicidality. In all, 68% of girls with eating disorders had a positive score in the Children’s Depression Inventory questionnaire and 62% of them in the Child Adolescent Suicidal Potential Index questionnaire. Clinical examination of girls with eating disorders should focus on identifying the risk of suicidal behavior and self-harm.

Abstract While an extensive literature supports the notion that mesocorticolimbic dopamine plays a role in negative reinforcement, recent evidence suggests that dopamine exclusively encodes the value of positive reinforcement. In the present study, we employed a behavioral economics approach to investigate whether dopamine plays a role in the valuation of negative reinforcement. Using rats as subjects, we first applied fast-scan cyclic voltammetry (FSCV) to determine that dopamine concentration decreases with the number of lever presses required to avoid electrical footshock (i.e., the economic price of avoidance). Analysis of the rate of decay of avoidance demand curves, which depict an inverse relationship between avoidance and increasing price, allows for inference of the worth an animal places on avoidance outcomes. Rapidly decaying demand curves indicate increased price sensitivity, or low worth placed on avoidance outcomes, while slow rates of decay indicate reduced price sensitivity, or greater worth placed on avoidance outcomes. We therefore used optogenetics to assess how inducing dopamine release causally modifies the demand to avoid electrical footshock in an economic setting. Increasing release at an avoidance predictive cue made animals more sensitive to price, consistent with a negative reward prediction error (i.e., the animal perceives they received a worse outcome than expected). Increasing release at avoidance made animals less sensitive to price, consistent with a positive reward prediction error (i.e., the animal perceives they received a better outcome than expected). These data demonstrate that transient dopamine release events represent the value of avoidance outcomes and can predictably modify the demand to avoid. PMID:29766047

2016-11-01

Despite the robust associations between stressors and anxiety in dementia caregiving, there is a lack of research examining which factors contribute to explain this relationship. This study was designed to test a multiple mediation model of behavioral and psychological symptoms of dementia (BPSD) and anxiety that proposes higher levels of rumination and experiential avoidance and lower levels of leisure satisfaction as potential mediating variables. The sample consisted of 256 family caregivers. In order to test a simultaneously parallel multiple mediation model of the BPSD to anxiety pathway, a PROCESS method was used and bias-corrected and accelerated bootstrapping method was used to test confidence intervals. Higher levels of stressors significantly predicted anxiety. Greater stressors significantly predicted higher levels of rumination and experiential avoidance, and lower levels of leisure satisfaction. These three coping variables significantly predicted anxiety. Finally, rumination, experiential avoidance, and leisure satisfaction significantly mediated the link between stressors and anxiety. The explained variance for the final model was 47.09%. Significant contrasts were found between rumination and leisure satisfaction, with rumination being a significantly higher mediator. The results suggest that caregivers' experiential avoidance, rumination, and leisure satisfaction may function as mechanisms through which BPSD influence on caregivers' anxiety. Training caregivers in reducing their levels of experiential avoidance and rumination by techniques that foster their ability of acceptance of their negative internal experiences, and increase their level of leisure satisfaction, may be helpful to reduce their anxiety symptoms developed by stressors.

Drug policy, harm and human rights: a rationalist approach.

Science.gov (United States)

Stevens, Alex

2011-05-01

It has recently been argued that drug-related harms cannot be compared, so making it impossible to choose rationally between various drug policy options. Attempts to apply international human rights law to this area are valid, but have found it difficult to overcome the problems in applying codified human rights to issues of drug policy. This article applies the rationalist ethical argument of Gewirth (1978) to this issue. It outlines his argument to the 'principle of generic consistency' and the hierarchy of basic, nonsubtractive and additive rights that it entails. It then applies these ideas to drug policy issues, such as whether there is a right to use drugs, whether the rights of drug 'addicts' can be limited, and how different harms can be compared in choosing between policies. There is an additive right to use drugs, but only insofar as this right does not conflict with the basic and nonsubtractive rights of others. People whose freedom to choose whether to use drugs is compromised by compulsion have a right to receive treatment. They retain enforceable duties not to inflict harms on others. Policies which reduce harms to basic and nonsubtractive rights should be pursued, even if they lead to harms to additive rights. There exists a sound, rational, extra-legal basis for the discussion of drug policy and related harms which enables commensurable discussion of drug policy options. Copyright © 2011 Elsevier B.V.

Do no harm: a defense of markets in healthcare.

Science.gov (United States)

Kline, William

2010-09-01

This paper argues that the rules that constitute a market protect autonomy and increase welfare in healthcare. Markets do the former through protecting rights to self-ownership and a cluster of rights that protect its exercise. Markets protect welfare by organizing and protecting trades. In contrast, prohibition destroys legitimate markets, giving rise to so-called black markets that harm both the autonomy and well-being of agents. For example, a fee-for-service medical system is a highly developed and specialized market. It is individuals working together, through the division of labor, to provide mutual insurance. This coordination, and the benefits it makes possible, is not possible without injunctions against harm. Prohibitions on harm are not mere ethical niceties, they are practice rules for both healthcare and markets. Placing the doctor within a healthcare market actually reinforces the doctor's moral obligation, and the legal enforcement of that obligation, not to harm. Similarly, markets reinforce patient rights to self-determination through legal and institutional enforcement of the harm principle in the form of the protection of certain basic welfare rights to life, bodily integrity, property, trade, and contract. Since the establishment of markets protects agent autonomy and welfare, and prohibition directly harms the same, there are strong reasons for establishing markets to protect trade in precisely those areas where autonomy and well-being are most vulnerable to exploitation, for example, the trade in human kidneys.

A Crowd Avoidance Method Using Circular Avoidance Path for Robust Person Following

Directory of Open Access Journals (Sweden)

Kohei Morishita

2017-01-01

Full Text Available A life-support service robot must avoid both static and dynamic obstacles for working in a real environment. Here, a static obstacle means an obstacle that does not move, and a dynamic obstacle is the one that moves. Assuming the robot is following a target person, we discuss how the robot avoids a crowd through which the target person passes and arrives at the target position. The purpose of this paper is to propose a crowd avoidance method that makes a robot to be able to avoid both static and dynamic obstacles. The method uses the surface points of the obstacles to form an avoidance region, and the robot moves along the edge of the region. We conducted experiments assuming various situations such that the robot was blocked, there was a wide gap in the crowd, or a person in the crowd yielded for the robot to pass through. As an experimental result, it was confirmed the robot could avoid the crowd even when the obstacles were aligned in an “inverted wedge” shape.

Duty to warn of genetic harm in breach of patient confidentiality.

Science.gov (United States)

Keeling, Sharon L

2004-11-01

Harm caused by the failure of health professionals to warn an at-risk genetic relative of her or his risk is genetic harm. Genetic harm should be approached using the usual principles of negligence. When these principles are applied, it is shown that (a) genetic harm is foreseeable; (b) the salient features of vulnerability, the health professional's knowledge of the risk to the genetic relative and the determinancy of the affected class and individual result in a duty of care being owed to the genetic relative; (c) the standard of care required to fulfil the duty to warn should be the expectations of a reasonable person in the position of the relative; and (d) causation is satisfied as the harm is caused by the failure of intervention of the health professional. Legislation enacted subsequent to the Report of the Commonwealth of Australia, Panel of Eminent Persons (Chair D Ipp), Review of the Law of Negligence Report (2002) and relevant to a duty to warn of genetic harm is considered. The modes of regulation and penalties for breach of any future duty to warn of genetic harm are considered.

Level ofaggression and sense of control inself-harming youth receiving psychiatric treatment

Full Text Available Acts of autoaggression are a more and more frequent reason for psychiatric hospitalisation of adolescents. Within the last years the number of patients committing acts of deliberate self‑harm without suicidal intensions almost doubled. Deliberate self‑harm (DSH is defined as an act of direct destructiveness, in which a person wants to commit self‑harm immediately, without an intention of killing her/himself. In this paper we present the results of the study on the level and direction of aggression and the sense of control among inpatients (N=187 of the Department of Adolescent Psychiatry, Central University Hospital in Łódź. The studied group consisted of patients with deliberate self‑harm (DSH group, N=88, whereas the control group comprised the patients without such behaviours (non‑DSH group, N=99. For the study we recruited patients who were admitted to the hospital due to various mental disorders – 58 boys, mean age 16.81, SD=1.25, and 129 girls, mean age 16.5, SD=1.38. The mean age of all patients was 16.59 (SD=1.35. Patients with men‑ tal retardation were excluded from the study, due to expected difficulties with understanding the questions. We used the IPSA (Inventory of Psychological Syndrome of Aggression and “Delta” (test invented by Drwal, designed for evalua‑ tion of the sense of control. In the DSH group we found a significantly higher level of aggression, directed both inwards and outwards, a greater tendency of retaliatory behaviours and by far lower sense of internal control of one’s behaviours, as compared to the non‑DSH group. Therapeutic programs for patients with DSH should aim at the reduction of aggres‑ sion and the development of internal control over one’s behaviours.

Airborne Collision Detection and Avoidance for Small UAS Sense and Avoid Systems

Science.gov (United States)

Sahawneh, Laith Rasmi

The increasing demand to integrate unmanned aircraft systems (UAS) into the national airspace is motivated by the rapid growth of the UAS industry, especially small UAS weighing less than 55 pounds. Their use however has been limited by the Federal Aviation Administration regulations due to collision risk they pose, safety and regulatory concerns. Therefore, before civil aviation authorities can approve routine UAS flight operations, UAS must be equipped with sense-and-avoid technology comparable to the see-and-avoid requirements for manned aircraft. The sense-and-avoid problem includes several important aspects including regulatory and system-level requirements, design specifications and performance standards, intruder detecting and tracking, collision risk assessment, and finally path planning and collision avoidance. In this dissertation, our primary focus is on developing an collision detection, risk assessment and avoidance framework that is computationally affordable and suitable to run on-board small UAS. To begin with, we address the minimum sensing range for the sense-and-avoid (SAA) system. We present an approximate close form analytical solution to compute the minimum sensing range to safely avoid an imminent collision. The approach is then demonstrated using a radar sensor prototype that achieves the required minimum sensing range. In the area of collision risk assessment and collision prediction, we present two approaches to estimate the collision risk of an encounter scenario. The first is a deterministic approach similar to those been developed for Traffic Alert and Collision Avoidance (TCAS) in manned aviation. We extend the approach to account for uncertainties of state estimates by deriving an analytic expression to propagate the error variance using Taylor series approximation. To address unanticipated intruders maneuvers, we propose an innovative probabilistic approach to quantify likely intruder trajectories and estimate the probability of

The Gambling Act 2003 mandated a public health strategy for preventing and minimising gambling harm in New Zealand. Aware Communities and Supportive Communities are two public health programmes subsequently implemented nationwide. These programmes differed from common health promotion initiatives such as media or education campaigns as they were community-action based (requiring community involvement in programme planning and delivery). We carried out a process evaluation to determine their implementation effectiveness and inform improvement and future programme planning. Our qualitative dominant mixed methods design comprised analysis of over a hundred implementer progress reports (submitted July 2010 - June 2013), a staff survey and a staff focus group interview. The programmes demonstrated capacity to not only achieve expected outcomes (e.g. enhanced community awareness about harmful gambling), but also to enhance social sustainability at the community level (e.g. established trustful relationships) and achieve some programme sustainability (e.g. community ownership over ongoing programme delivery). The evaluation noted the potential for a sustainable gambling harm-minimisation model. Community-action based harm-minimisation programmes offer programme sustainability potential which in turn offers funding cost-effectiveness when there are continual public health outcomes beyond initial funding. Although resource intensive, the community-action based approach enables culturally appropriate public health programmes suitable for societies where specific ethnic groups have higher gambling risk. Recognition of such harm-minimisation programmes' contribution to social sustainability is important considering the potential for broader public health outcomes (e.g. better life quality, lesser social problems) within socially sustainable societies.

Self-harm in children placed in a Court-Mandated Holding and Education Centre: analysis of socio-demographic variables and influence of implementation of judicial measures

Full Text Available Objectives: To analyze and understand the existence of self-harming behavior in a detention centre for minors. Methods: Review of self-harm cases detected in a population of 94 inmates in 2013. Results: 26.5% of young offenders have conducted some form of self injury. 28% of individuals with self harming behaviors have more than 6 episodes over the period of internment. Self-beating is the most common type of self-harm performed by this group. Inmates serving sentences in the therapeutic section tend to present spillover effects in terms of self-injury. Discussion: The population held in prison show higher percentages of self-harm than amongst the general population. The chosen type of behavior is determined by the institution. Inmates that present greater mental fragility tend to perform these behaviors and in greater number.

A primary goal of dialectical behaviour therapy (DBT) is to reduce self-harm, but findings from empirical studies are inconclusive. The aim of this study was to assess the effectiveness and cost-effectiveness of DBT in reducing self-harm in patients with personality disorder. Participants with a personality disorder and at least 5 days of self-harm in the previous year were randomised to receive 12 months of either DBT or treatment as usual (TAU). The primary outcome was the frequency of days with self-harm; secondary outcomes included borderline personality disorder symptoms, general psychiatric symptoms, subjective quality of life, and costs of care. Forty patients each were randomised to DBT and TAU. In an intention-to-treat analysis, there was a statistically significant treatment by time interaction for self-harm (incidence rate ratio 0.91, 95% CI 0.89-0.92, p self-harm decreased by 9% relative to TAU. There was no evidence of differences on any secondary outcomes. The economic analysis revealed a total cost of a mean of 5,685 GBP (6,786 EUR) in DBT compared to a mean of 3,754 GBP (4,481 EUR) in TAU, but the difference was not significant (95% CI -603 to 4,599 GBP). Forty-eight per cent of patients completed DBT. They had a greater reduction in self-harm compared to dropouts (incidence rate ratio 0.78, 95% CI 0.76-0.80, p self-harm in patients with personality disorder, possibly incurring higher total treatment costs. The effect is stronger in those who complete treatment. Future research should explore how to improve treatment adherence. Copyright © 2012 S. Karger AG, Basel.

Full Text Available The aim of this study was to assess the prevalence of hazardous and harmful alcohol use and associated factors among patients with tuberculosis in South Africa. In a cross-sectional survey new tuberculosis (TB and TB retreatment patients were consecutively screened using the Alcohol Use Disorder Identification Test (AUDIT within one month of anti-tuberculosis treatment. The sample included 4,900 (54.5% men and women 45.5% tuberculosis patients from 42 primary care clinics in three districts. Results indicate that, overall 23.2% of the patients were hazardous or harmful alcohol drinkers, 31.8% of men and 13.0% of women were found to be hazardous drinkers, and 9.3% of men and 3.4% of women meet criteria for probable alcohol dependence (harmful drinking as defined by the AUDIT. Men had significantly higher AUDIT scores than women. In multivariable analyses it was found that among men poor perceived health status, tobacco use, psychological distress, being a TB retreatment patient and not being on antiretroviral therapy (ART, and among women lower education, tobacco use and being a TB retreatment patient were associated with hazardous or harmful alcohol use. The study found a high prevalence of hazardous or harmful alcohol use among tuberculosis primary care patients. This calls for screening and brief intervention and a comprehensive alcohol treatment programme as a key component of TB management in South Africa.

Full Text Available Presence of harmful insects and mites is almost inevitable in mercantile wheat stored in warehouses. They cause significant damages and therefore it is necessary to perform pest control and chemical treatment. Study of harmful and destructive entomophauna impacts on quality of mercantile wheat and flour has been presented. Mercantile wheat stored in silos has been used in the study. Testing of quality of rheological properties and presence of harmful entomophauna were done in the labs within the silos «Žitoprerada d.o.o. Valpovo « and Department of Plant Protection on Faculty of Agriculture in Osijek. Presence of harmful entomophauna, quality of mercantile wheat stored in a warehouse and rheological flour properties were determined. The following harmful entomophauna were found: mites (Acarinae, primary pests of order Coleoptera and Lepidoptera, secondary pests of order Coleoptera and other insects found belong to Coleoptera, Psocoptera and useful insects of Hymenoptera orders. Influence of harmful entomophauna on quality of mercantile wheat is manifested by reduced quality of stored wheat due to decrease of water content and hectoliter mass. Lower quality of flour obtained by milling of infected wheat is manifested by change in rheological properties: dough stability, water absorption, growth, resistance, energy, extensibility, maximum resistance, start of puffing up, and viscosity.

Neural correlates of conventional and harm/welfare-based moral decision-making.

The degree to which social norms are processed by a unitary system or dissociable systems remains debated. Much research on children's social-cognitive judgments has supported the distinction between "moral" (harm/welfare-based) and "conventional" norms. However, the extent to which these norms are processed by dissociable neural systems remains unclear. To address this issue, 23 healthy participants were scanned with functional magnetic resonance imaging (fMRI) while they rated the wrongness of harm/welfare-based and conventional transgressions and neutral vignettes. Activation significantly greater than the neutral vignette baseline was observed in regions implicated in decision-making regions including rostral/ventral medial frontal, anterior insula and dorsomedial frontal cortices when evaluating both harm/welfare-based and social-conventional transgressions. Greater activation when rating harm/welfare-based relative to social-conventional transgressions was seen through much of ACC and bilateral inferior frontal gyrus. Greater activation was observed in superior temporal gyrus, bilateral middle temporal gyrus, left PCC, and temporal-parietal junction when rating social-conventional transgressions relative to harm/welfare-based transgressions. These data suggest that decisions regarding the wrongness of actions, irrespective of whether they involve care/harm-based or conventional transgressions, recruit regions generally implicated in affect-based decision-making. However, there is neural differentiation between harm/welfare-based and conventional transgressions. This may reflect the particular importance of processing the intent of transgressors of conventional norms and perhaps the greater emotional content or salience of harm/welfare-based transgressions.

Full Text Available Objective This study addresses how experienced harm from other people's drinking varies between six Northern European countries by comparing 1 the prevalence of experienced harm and 2 the correlates of harm. Method The data comprise 18ȓ69-year olds who participated in general population surveys in Denmark, Finland, Iceland, Norway, Sweden, and Scotland during the period 2008–2013. Comparative data were available on five types of harm: physical abuse, damage of clothes/belongings, verbal abuse, being afraid, and being kept awake at night. Results This study shows that harms from other's drinking are commonly experienced in all six countries. Being kept awake at night is the most common harm, while being physically harmed is the least common. The proportions that reported at least one of the five problems were highest in Finland and Iceland and lowest in Norway, but also relatively low in Sweden. Across countries, the level of harm was highest among young, single, urban residents, and for some countries among women and those who frequently drank to intoxication themselves. Conclusions The study revealed large differences in the prevalence of harm in countries with fairly similar drinking cultures. However, the correlates of such experiences were similar across countries. Possible explanations of the findings are discussed, including differences in study design.

E-cigarette Regulation and Harm Reduction: The Case of Hong Kong.

Science.gov (United States)

Churk, Shue Sing

Harm reduction is an internationally recognized tobacco control strategy. E-cigarettes, being a less harmful alternative to smoking, have the potential to achieve harm reduction. Within this context, this article critiques Hong Kong’s legal regime governing e-cigarettes and the proposed prohibition of the product. It is argued that the current law is uncertain and inadequate. Although a reform of laws relating to e-cigarettes is needed, it is argued that banning the product altogether as a means to reducing the harm of tobacco use is unsupported by evidence.

An Examination of Avoided Costs in Utah

Energy Technology Data Exchange (ETDEWEB)

Bolinger, Mark; Wiser, Ryan

2005-01-07

The Utah Wind Working Group (UWWG) believes there are currently opportunities to encourage wind power development in the state by seeking changes to the avoided cost tariff paid to qualifying facilities (QFs). These opportunities have arisen as a result of a recent renegotiation of Pacificorp's Schedule 37 tariff for wind QFs under 3 MW, as well as an ongoing examination of Pacificorp's Schedule 38 tariff for wind QFs larger than 3 MW. It is expected that decisions made regarding Schedule 38 will also impact Schedule 37. Through the Laboratory Technical Assistance Program (Lab TAP), the UWWG has requested (through the Utah Energy Office) that LBNL provide technical assistance in determining whether an alternative method of calculating avoided costs that has been officially adopted in Idaho would lead to higher QF payments in Utah, and to discuss the pros and cons of this method relative to the methodology recently adopted under Schedule 37 in Utah. To accomplish this scope of work, I begin by summarizing the current method of calculating avoided costs in Utah (per Schedule 37) and Idaho (the ''surrogate avoided resource'' or SAR method). I then compare the two methods both qualitatively and quantitatively. Next I present Pacificorp's four main objections to the use of the SAR method, and discuss the reasonableness of each objection. Finally, I conclude with a few other potential considerations that might add value to wind QFs in Utah.

Full Text Available Background and Design: The aim of the study was to evaluate harmful effects of sun exposure and knowledge, attitude and behaviors related to sun protection among patients attending our outpatient clinic. Materials and Methods: A total of 400 patients (171 male and 229 female aged between 16 and 89 years were included in this study. Subjects were requested to fill out a questionnaire composed of 52 questions. In the first part of the questionnaire, patients’ socio-demographic characteristics, history of sunburn, first-degree relatives with a history of skin cancer; in the second part, knowledge about harmful effects of sun and sun protection were inquired. In the third part, patient attitude and behaviors related to sun protection was evaluated. Results: Our results revealed that 69.25% of patients had satisfactory level of knowledge. While the level of knowledge was not affected by economic status, place of residence, skin type and presence of skin cancer in participants or their first-degree relatives, it was found to be increased with increasing educational level. The patients were found to prefer avoiding mid-day sun (75.5% and staying in the shade (64.8% chiefly as sun protection methods and 45.3% of patients were found to use sunscreens. Most frequently preferred sources of information about harmful effects of the sun and sun protection methods were found to be television, magazines and newspapers (76.3%, doctor’s advice and internet, respectively. Conclusion: Although a satisfactory level of knowledge about harmful effects of the sun and protection methods was found, it was observed that individuals could not convert their knowledge into the sun protection behavior

Dealing with difficult days: Functional coping dynamics in self-harm ideation and enactment.

Self-harm affords people a means of coping. However, little is known about how functional coping dynamics differ between stressful situations in which people self-harm (enactment), think about harming (ideation), or experience no self-harmful thoughts or behaviours. Participants (N = 1,157) aged 16-49 years (M = 18.21, SD = 3.24) with a recent history of self-harm (past 3 months) reported how they coped in response to their most significant recent stressor (3 months). Almost 40% of participants, all of whom had self-harmed in the last 3 months, had no self-harm experience (thoughts or behaviours) in response to their most significant stressor in that time frame. In multivariate analysis, adjusting for symptoms of depression and anxiety, reappraisal coping was predictive of self-harm thoughts. Approach, emotion regulation and reappraisal coping were predictive of self-harm behaviour. Emotion regulation coping differentiated self-harm ideation and enactment groups. The cross-sectional design of the study precludes the ability to make inferences regarding causality. Further, there is no agreed definition of 'recent' self-harm. Taken together, the findings suggest that functional coping dynamics may be differentially associated with self-harm ideation and enactment. This is important, given that understanding the transitions between ideation and enactment has been identified as a critical frontier in suicide prevention. Further, results indicate that seemingly innocuous events may have a profound impact as tipping points for enaction; this has implications for clinical practice, including the co-production of safety plans.

Clustering of adolescent self-harming behaviours in the context of health care utilization has not been studied. We identified geographic areas with higher numbers of adolescents who (1) presented to an emergency department (ED) for self-harm, and (2) were without a physician follow-up visit for mental health within 14 days post-ED visit. We extracted a population-based cohort of adolescents aged 15-17 years (n = 3,927) with ED visits during 2002-2011 in Alberta, Canada. We defined the case as an individual with one or more ED presentations for self-harm in the fiscal year of the analysis. Crude case rates were calculated and clusters were identified using a spatial scan. The rates decreased over time for ED visits for self-harm (differences: girls -199.6/100,000; p self-harm (differences: girls -108.3/100,000; p self-harm (relative risks [RRs]: 1.58 for cluster 1, 3.54 for cluster 2) and were without a 14-day physician follow-up (RRs: 1.78 for cluster 1, 4.17 for cluster 2). In 2010/2011, clusters in the North, Edmonton, and Central zones were identified for adolescents with and without a follow-up visit within 14 days following an ED visit for self-harm (p self-harm and rates of adolescents without a 14-day physician follow-up visit following emergency care for self-harm decreased during the study period. The space-time clusters identified the areas and years where visits to the ED by adolescents for self-harm were statistically higher than expected. These clusters can be used to identify locations where adolescents are potentially not receiving follow-up and the mental health support needed after emergency-based care. The 2010/2011 geographic cluster suggests that the northern part of the province still has elevated numbers of adolescents visiting the ED for self-harm. Prospective research is needed to determine outcomes associated with adolescents who receive physician follow-up following ED-based care for self-harm compared to those who do not.

To summarize and compare evidence on harms in sildenafil- and placebo-treated men with erectile dysfunction (ED) in a systematic review and meta-analysis. Randomized placebo-controlled trials (RCTs) were identified using an electronic search in MEDLINE, EMBASE, PsycINFO, SCOPUS, and Cochrane CENTRAL. The rates of any adverse events (AEs), most commonly reported AEs, withdrawals because of adverse events, and serious adverse events were ascertained and compared between sildenafil and placebo groups. The results of men with ED were stratified by clinical condition(s). Statistical heterogeneity was explored. Meta-analyses based on random-effects model were also performed. A total of 49 RCTs were included. Sildenafil-treated men had a higher risk for all-cause AEs (RR = 1.56, 95% CI: 1.38, 1.76), headache, flushing, dyspepsia, and visual disturbances compared with placebo-treated men. The magnitude of excess risk was greater in fixed- than in flexible-dose trials. The rates of serious adverse events and withdrawals because of adverse events did not differ in sildenafil vs placebo groups. A higher dose of sildenafil corresponded to a greater risk of AEs. The increased risk of harms was observed within and across clinically defined specific groups of patients. There was a lack of RCTs reporting long-term (>6 months) harms data. In short-term trials, men with ED randomized to sildenafil had an increased risk of all-cause any AEs, headache, flushing, dyspepsia, and visual disturbances. The exploration of different modes of dose optimization of sildenafil may be warranted.

Evaluation of psychological distress has received relatively little attention in research on persons with disorders of sex development (DSD). Results of previous studies varied considerably, but most studies did not find increased levels of psychological distress. We conducted a pilot study based on a sample of 37 persons with diverse forms of DSD recruited via various strategies. The Brief Symptom Inventory (BSI) was used to assess self-reported psychological distress. Psychological distress varied broadly across all diagnostic subgroups. Overall, the BSI Global Severity Index indicated higher distress in the sample of persons with DSD compared to a non-clinical norm population of women, with an effect size of d = 0.67. According to predefined BSI criteria, 59% of participants were classified as a clinical case. Self-harming behavior and suicidal tendencies were also assessed and compared to a community based sample of women, including subgroups of traumatized women with a history of physical or sexual abuse. The prevalence rates of self-harming behavior and suicidal tendencies in the DSD sample exceeded the rates of the non-traumatized comparison subgroup, with rates comparable to the traumatized comparison groups of women with physical or sexual abuse. As possible explanations for the higher distress found here compared to most previous studies, differences in measures and sample recruitment are discussed. Our results suggest that adults with DSD are markedly psychologically distressed with rates of suicidal tendencies and self-harming behavior on a level comparable to non-DSD women with a history of physical or sexual abuse, but sample recruitment procedures do not permit a firm generalization.

Market penetration of intersection AEB: Characterizing avoided and residual straight crossing path accidents.

Car occupants account for one third of all junction fatalities in the European Union. Driver warning can reduce intersection accidents by up to 50 percent; adding Autonomous Emergency Braking (AEB) delivers a reduction of up to 70 percent. However, these findings are based on an assumed 100 percent equipment rate, which may take decades to achieve. Our study investigates the relationship between intersection AEB market penetration rates and avoidance of accidents and injuries in order to guide implementation strategies. Additionally, residual accident characteristics (impact configurations and severity) are analyzed to provide a basis for future in-crash protection requirements. We determined which accidents would have been avoided through the use of an Intersection AEB system with different sensor field-of-views (180° and 120°) by means of re-simulating the pre-crash phase of 792 straight crossing path (SCP) car-to-car accidents recorded in the German In-Depth Accident Study (GIDAS) and the associated Pre-Crash Matrix (PCM). Intersection AEB was activated when neither of the conflict opponents could avoid the crash through reasonable braking or steering reactions. For not-avoided accidents, we used the Kudlich-Slibar rigid body impulse model to calculate the change of velocity during the impact as a measure of impact severity and the principal direction of force. Accident avoidance over market penetration is not linear but exponential, with higher gains at low penetration rates and lower gains at higher rates. A wide field-of-view sensor (180°) substantially increased accident avoidance and injury mitigation rates compared to a 120° field-of-view sensor. For a 180° field-of-view sensor at 100 percent market penetration, about 80 percent of the accidents and 90 percent of the MAIS2 + F injuries could be avoided. For the remaining accidents, AEB intervention rarely affected side of impact. The median change of velocity (delta-V) of the remaining crashes

This study compared acutely ill patients with schizophrenia with a history of self-harm (N=17) to those without a history of self-harm (N=16) on measures of depression, hopelessness, suicidal ideation, and demographic and psychiatric variables. A subgroup of these patients who experience auditory hallucinations, with and without a history of self-harm, were selected and compared on measures of depression, hopelessness, suicidal ideation and beliefs about voices. Employing a cross-sectional design, in-patients of two local psychiatric hospital, who met DSM-IV-TR criteria for schizophrenia and who were in an acute phase of the illness, were selected. Each patient was assessed using the Beck Depressions Inventory (BDI), Beck Hopelessness Scale (BHS) and the Beck Suicide Scale (BSS). Patients who experienced auditory verbal hallucinations completed the Beliefs About Voices Questionnaire Revised (BAVQ-R). Patients with a history of self-harm completed the Beck Suicide Intent Scale (BSI). Patients with a history of self-harm (N=17) had significantly greater symptoms of depression, greater suicidal thoughts, increased number of hospital admissions, greater duration of illness and were more likely to be married, compared to patients without a history of self-harm (N=16). Among the subgroup of patients who experience auditory hallucinations, those with a history of self-harm (N=9), believed their voice to be more malevolent, had a tendency to resist their voice and experienced significantly greater symptoms of depression and hopelessness compared to those without a history of self-harm (N=6). These findings highlight the importance for screening by clinicians during inpatient hospital stays and for monitoring to be ongoing following discharge. For the subgroup of patients who experience auditory hallucinations, future research should seek to explore the relationship between self-harm and beliefs about voices.

For reducting tobacco harm, this paper prepared an ordered mesoporous silica by using triblock copolymer Pluronic P123 as template. The property of this material was characterized by the X-ray scattering spectrum(XRD), Transmission electron microscopy(TEM), Scanning electron microscopy (SEM) and Nitrogen adsorption/desorption. Then this ordered mesoporous silica was added into the cigarette filter in order to researching its effect of cigarette harm index. The result shows that the feature of SBA-15 was grain morphology, ordered arrangement, tubular porous 2-D hexagonal structure. The application of SBA-15 in cigarette filter can selectively reduce harmful components in cigarette smoke such as crotonaldehyde, hydrogen cyanide, benzo pyrene and tar. The synthesized SBA-15 could properly reduce cigarette harm index.

[Harmful practices affecting women's health].

Science.gov (United States)

1990-07-01

The harmful practices discussed in this article are based on case histories form the Central Maternity in Niamey, yet these practices universally affect women throughout Africa. Nutritional taboos are aimed at certain diseases such as measles, diarrhea, dysentery, malnutrition and anemia and consumption of foods rich in proteins and lipids are forbidden. Children are forbidden from eating eggs; pregnant women are forbidden from eating fruits and vegetables because of the fear of hemorrhaging from the sugar content in the fruit; camel meat is forbidden for fear of extending the pregnancy. Female circumcision, a dangerous practice, especially during childbirth, causes many medical problems that remain permanent. Adolescent pregnancy and marriages are practiced to avoid delinquency among children; yet such practices take place because of arranged marriages for a dowry to young men or to older rich men and these forced marriages to adolescents are the causes of increases in divorce, prostitution and desertion. These young marriages have serious consequences on the health status of the mother and the infant, often leading to maternal and infant death. The high level of fertility in Niger is a response to the social structure of the family. It is a patrilineal system that encourages women to have many children, especially sons. In Niger, pregnancy is surrounded by supernatural and mysterious forces, where a child is the intervention for ancestral spirits. In Islam a child is considered a "Gift of God". A woman is expected to work until the delivery of her baby otherwise she is jeered by her neighbors. During delivery women are not expected to cry or show any pain for fear of dishonoring her family irregardless of any medical compilations she faces. Women in Africa are exploited as free labor, deteriorate and age rapidly, are generally illiterate and are not protected under any laws.

Learning-Based Detection of Harmful Data in Mobile Devices

Full Text Available The Internet has supported diverse types of multimedia content flowing freely on smart phones and tablet PCs based on its easy accessibility. However, multimedia content that can be emotionally harmful for children is also easily spread, causing many social problems. This paper proposes a method to assess the harmfulness of input images automatically based on an artificial neural network. The proposed method first detects human face areas based on the MCT features from the input images. Next, based on color characteristics, this study identifies human skin color areas along with the candidate areas of nipples, one of the human body parts representing harmfulness. Finally, the method removes nonnipple areas among the detected candidate areas using the artificial neural network. The experimental results show that the suggested neural network learning-based method can determine the harmfulness of various types of images more effectively by detecting nipple regions from input images robustly.

Decision-making in adolescent females who deliberately self-harm

Rigler Tristan

2016-01-01

Full Text Available Self-harming behaviour most commonly begins in adolescence and is more frequent among adolescent females. We explored the hypothesis that adolescent females who deliberately selfharm were more likely to perform worse on a decision-making task. Previous research in adolescents who self-harm reported impaired decision-making. However, research put little emphasis on older adolescents and the emotional learning. In our research, we presented the Iowa Gambling Task to 35 adolescent females who self-harmed and were treated at a psychiatric clinic, and to 35 healthy female controls. Our results show that in comparison to the control group the adolescents who self-harm took more risky decisions and were less concerned about the outcome. In addition, the clinical group also focused more on immediate gains and showed a reduced ability to learn from poor decisions in the past. Further research is suggested to explore the potential neurological correlates of decision-making and selfharming behaviour.

Mammography screening. Benefits, harms, and informed choice.

Jørgensen, Karsten Juhl

2013-04-01

The rationale for breast cancer screening with mammography is deceptively simple: catch it early and reduce mortality from the disease and the need for mastectomies. But breast cancer is a complex problem, and complex problems rarely have simple solutions. Breast screening brings forward the time of diagnosis only slightly compared to the lifetime of a tumour, and screen-detected tumours have a size where metastases are possible. A key question is if screening can prevent metastases, and if the screen-detected tumours are small enough to allow breast conserving surgery rather than mastectomy. A mortality reduction can never justify a medical intervention in its own right, but must be weighed against the harms. Overdiagnosis is the most important harm of breast screening, but has gained wider recognition only in recent years. Screening leads to the detection and treatment of breast cancers that would otherwise never have been detected because they grow very slowly or not at all and would not have been detected in the woman's lifetime in the absence of screening. Screening therefore turns women into cancer patients unnecessarily, with life-long physical and psychological harms. The debate about the justification of breast screening is therefore not a simple question of whether screening reduces breast cancer mortality. This dissertation quantifies the primary benefits and harms of screening mammography. Denmark has an unscreened "control group" because only two geographical regions offered screening over a long time-period, which is unique in an international context. This was used to study breast cancer mortality, overdiagnosis, and the use of mastectomies. Also, a systematic review of overdiagnosis in five other countries allowed us to show that about half of the screen-detected breast cancers are overdiagnosed. An effect on breast cancer mortality is doubtful in today's setting, and overdiagnosis causes an increase in the use of mastectomies. These findings are

Neuropsychological and emotional correlates of personality traits in Parkinson's disease.

Parkinson's disease (PD) is, apart from the well-known motor symptoms, also characterized by neuropsychological and emotional disturbances. However, patients also often present with a personality profile of low Novelty Seeking and high Harm Avoidance. This profile can be identified as the disease emerges, which raises the question whether these traits correlate with more fundamental neuropsychological and emotional disturbances. This study determined the neuropsychological and emotional correlates of Novelty Seeking, Harm Avoidance and two other personality traits that are often considered in PD, i.e. Reward Dependence and Persistence. Forty-three patients and 25 healthy participants were assessed with the Temperament and Character Inventory, a symptoms of depression questionnaire and neuropsychological tests. PD patients showed a higher Harm Avoidance than healthy participants, which was predicted by symptoms of depression. Groups did not differ regarding Novelty Seeking, Reward Dependence and Persistence. While cognitive flexibility was a predictor of Reward Dependence, Persistence was predicted by divergent thinking and inhibition. Novelty Seeking was not predicted by cognition or emotion. In conclusion, cognition and emotion are selectively related to personality traits in PD. Whereas Harm Avoidance covaries with emotional symptoms, Persistence and Reward Dependence are related to cognition. Alterations in personality, cognition and emotion in PD are thus not independent from each other.

Secondary harm mitigation: A more humanitarian framework for international drug law enforcement.

Science.gov (United States)

Blaustein, Jarrett; McLay, Miki; McCulloch, Jude

2017-08-01

This article introduces the concept of 'secondary harm mitigation' as a framework for improving the humanitarian credentials of international drug law enforcement agencies. The concept is rooted in a critical analysis of the compatibility of the harm reduction philosophy with Australia's international drug law enforcement practices. On a utilitarian level, the net benefits of international drug law enforcement are determined to be, at best inconclusive, arguably counterproductive and in most cases, incalculable. On a humanitarian level, international drug law enforcement is also determined to be problematic from a criminological standpoint because it generates secondary harms and it is indifferent to the vulnerability of individuals who participate in illicit drug trafficking. Accordingly, the article concludes that a philosophy of harm reduction grounded in the public health perspective is inadequate for mitigating secondary harms arising from Australia's efforts to combat international illicit drug trafficking. A tentative list of secondary harm mitigation principles is presented and the article argues that secondary harm mitigation should replace supply reduction as a core tenet of Australia's National Drug Strategy. The article also concludes that secondary harm mitigation may provide a viable framework for stimulating a productive dialogue between those who advocate prohibition and those who call for decriminalisation at the global level.

To examine whether alcohol's harms to others are more prevalent in socioeconomically disadvantaged neighbourhoods and whether men or women are at differential risk in these neighbourhoods. Cross-sectional survey data from 2000 and 2005 National Alcohol Surveys were linked to geo-referenced indicators of neighbourhood disadvantage from the US 2000 Decennial Census. The pooled sample included 10,121 adults (54% female; average age 44.4 years; 69% White; 13% African-American; 13% Hispanic). A dichotomous indicator denoted neighbourhoods based on the top quartile on a five-item measure of disadvantage (alpha = 0.90). We examined past-year family problems due to someone else's drinking (marriage difficulties and/or financial trouble) and victimisation by someone who had been drinking (having property vandalised and/or being pushed, hit or assaulted). During the prior 12 months, 6% of women and 3% of men experienced family problems from someone else's drinking, and 4% of women and 7% of men reported being victimised by drinkers. Multivariate logistic regression models adjusting for individual-level socioeconomic status and other demographic characteristics showed the relationship between neighbourhood disadvantage and harms from someone else's drinking was moderated by gender, with significantly higher odds of family problems in disadvantaged neighbourhoods for men but not for women, as well as significantly higher odds of crime victimisation in disadvantaged neighbourhoods for women but not men. Experiences of harms from someone else's drinking in disadvantaged neighbourhoods vary for men and women. Targeted intervention strategies are needed to reduce alcohol's harm to others. © 2014 Australasian Professional Society on Alcohol and other Drugs.

Stimulus conflict triggers behavioral avoidance.

Science.gov (United States)

Dignath, David; Eder, Andreas B

2015-12-01

According to a recent extension of the conflict-monitoring theory, conflict between two competing response tendencies is registered as an aversive event and triggers a motivation to avoid the source of conflict. In the present study, we tested this assumption. Over five experiments, we examined whether conflict is associated with an avoidance motivation and whether stimulus conflict or response conflict triggers an avoidance tendency. Participants first performed a color Stroop task. In a subsequent motivation test, participants responded to Stroop stimuli with approach- and avoidance-related lever movements. These results showed that Stroop-conflict stimuli increased the frequency of avoidance responses in a free-choice motivation test, and also increased the speed of avoidance relative to approach responses in a forced-choice test. High and low proportions of response conflict in the Stroop task had no effect on avoidance in the motivation test. Avoidance of conflict was, however, obtained even with new conflict stimuli that had not been presented before in a Stroop task, and when the Stroop task was replaced with an unrelated filler task. Taken together, these results suggest that stimulus conflict is sufficient to trigger avoidance.

Drug-Avoidance Self-Efficacy Among Exclusive Cannabis Users vs. Other Drug Users Visiting the Emergency Department.

Medical care in the emergency department (ED) is a growing and complex area of outpatient care, with about 256 visits made to EDs every minute in 2013. Studies report that, compared to people who do not use drugs, people who use illicit drugs are more likely to use the ED for their medical care. Self-efficacy has been shown to be a predictor of abstinence or reduced use among drug-using individuals. The current study describes drug avoidance self-efficacy among exclusive cannabis-using individuals and other drug-using individuals who use the ED for any reason. Participants were 693 adult patients visiting the trauma units and EDs of two large urban "safety net" hospitals (i.e., providing care to low-income, uninsured, and vulnerable population) in Southern California who reported using illicit drugs in the past 30 days. For people who use only cannabis, higher drug-avoidance self-efficacy was associated with older age, lower drug involvement scores, lower drug severity scores, and higher readiness to change use. For people who use other drugs, higher drug avoidance self-efficacy scores was associated with lower drug severity scores, lower psychiatric severity scores, higher medical severity scores, and higher readiness to change use. This study identified several factors (some common, some unique) related to higher drug-avoidance self-efficacy for both groups. Results may be important when designing intervention protocols for use in the ED.

Exposure therapy has proven efficacy in the treatment of posttraumatic stress disorder (PTSD). Emotional processing theory proposes that fear habituation is a central mechanism in symptom reduction, but the empirical evidence supporting this is mixed. Recently it has been proposed that violation of harm expectancies is a crucial mechanism of action in exposure therapy. But to date, changes in harm expectancies have not been examined during exposure therapy in PTSD. The goal of the current study was to examine harm expectancy violation as mechanism of change in exposure therapy for posttraumatic stress disorder (PTSD). Patients (N=50, 44 female) with a primary diagnosis of chronic PTSD received intensive exposure therapy. Harm expectancies, harm experiences and subjective units of distress (SUDs) were assessed at each imaginal exposure session, and PTSD symptoms were assessed pre- and posttreatment with the Clinician Administered PTSD Scale (CAPS). Results showed that harm expectancies were violated within and strongly declined in-between exposure therapy sessions. However, expectancy violation was not related to PTSD symptom change. Fear habituation measures were moderately related to PTSD symptom reductions. In line with theory, exposure therapy promotes expectancy violation in PTSD patients, but this is not related to exposure therapy outcome. More work is warranted to investigate mechanisms of change during exposure therapy in PTSD. Copyright © 2017 Elsevier Ltd. All rights reserved.

Women's participation in, and harm from gambling, is steadily increasing. There has been very limited research to investigate how gambling behaviour, product preferences, and perceptions of gambling harm may vary across subgroups of women. This study surveyed a convenience sample of 509 women from Victoria and New South Wales, Australia. Women were asked a range of questions about their socio-demographic characteristics and gambling behaviour. Focusing on four gambling products in Australia-casino gambling, electronic gambling machines (EGMs), horse betting, and sports betting-women were asked about their frequency of participation, their product preferences, and perceptions of product harms. The sample was segmented a priori according to age and gambling risk status, and differences between groups were identified using Chi-square tests and ANOVAs. Thematic analysis was used to interpret qualitative data. Almost two thirds (n = 324, 63.7%) of women had engaged with one of the four products in the previous 12 months. Compared to other age groups, younger women aged 16-34 years exhibited a higher proportion of problem gambling, gambled more frequently, and across more products. While EGMs were the product gambled on most frequently by women overall, younger women were significantly more likely to bet on sports and gamble at casinos relative to older women. Qualitative data indicated that younger women engaged with gambling products as part of a "night out", "with friends", due to their "ease of access" and perceived "chance of winning big". There were significant differences in the perceptions of the harms associated with horse and sports betting according to age and gambling risk status, with younger women and gamblers perceiving these products as less harmful. This study highlights that there are clear differences in the gambling behaviour, product preferences, and perceptions of product harms between subgroups of women. A gendered approach will enable public

Full Text Available Self-harm is prevalent in incarcerated adults, yet comparatively few studies of self-harm in detained youth (and even fewer in low- and middle-income countries have been published. We examined the prevalence and correlates of self-harm in a sample of 181 young people (mean age 15.0 years, SD = 2.3 detained in the youth justice system in Sri Lanka. Structured face-to-face questionnaires assessed demographic characteristics, family and social background, substance use, self-harm history (including frequency, method, and intention, bullying victimization, physical and sexual abuse (victimization and perpetration, and exposure to self-harm/suicide by others. Seventy-seven participants (43% reported a lifetime history of self-harm, 19 of whom (25% who reported doing so with suicidal intent. Fifty participants (65% of those with a history of self-harm reported engaging in self-harm impulsively, with no prior planning. A history of self-harm was associated with being female, prior sexual abuse victimization, prior exposure to self-harm by friends, and a lifetime history of self-harm ideation. High rates of substance use, bullying victimization, parental incarceration, and exposure to suicide were reported across the sample. Young people detained in the youth justice system in Sri Lanka are a vulnerable group with high rates of self-harm, substance use, and psychosocial risk factors. Strategies for identifying and preventing self-harm, and targeted psychological interventions designed specifically to address impulsivity, may contribute to more positive outcomes in this marginalised population.

Background Cannabis use is becoming more accepted in mainstream society. In this paper, we use Zinberg’s classic theoretical framework of drug, set, and setting to elucidate how older adult cannabis users managed health, social and legal risks in a context of normalized cannabis use. Methods We present selected findings from our qualitative study of Baby Boomer (born 1946–1964) cannabis users in the San Francisco Bay Area. Data collection consisted of a recorded, in-depth life history interview followed by a questionnaire and health survey. Qualitative interviews were analyzed to discover the factors of cannabis harm reduction from the users’ perspectives. Results Interviewees made harm reduction choices based on preferred cannabis derivatives and routes of administration, as well as why, when, where, and with whom to use. Most interviewees minimized cannabis-related harms so they could maintain social functioning in their everyday lives. Responsible and controlled use was described as moderation of quantity and frequency of cannabis used, using in appropriate settings, and respect for non-users. Users contributed to the normalization of cannabis use through normification. Conclusion Participants followed rituals or cultural practices, characterized by sanctions that helped define “normal” or “acceptable” cannabis use. Users contributed to cannabis normalization through their harm reduction methods. These cultural practices may prove to be more effective than formal legal prohibitions in reducing cannabis-related harms. Findings also suggest that users with access to a regulated market (medical cannabis dispensaries) were better equipped to practice harm reduction. More research is needed on both cannabis culture and alternative routes of administration as harm reduction methods. PMID:25911027

Studies have shown that adolescents with a history of both suicide attempts and non-suicidal self-harm report more mental health problems and other psychosocial problems than adolescents who report only one or none of these types of self-harm. The current study aimed to examine the use of child and adolescent psychiatric services by adolescents with both suicide attempts and non-suicidal self-harm, compared to other adolescents, and to assess the psychosocial variables that characterize adolescents with both suicide attempts and non-suicidal self-harm who report contact. Data on lifetime self-harm, contact with child and adolescent psychiatric services, and various psychosocial risk factors were collected in a cross-sectional sample (response rate = 92.7%) of 11,440 adolescents aged 14-17 years who participated in a school survey in Oslo, Norway. Adolescents who reported any self-harm were more likely than other adolescents to have used child and adolescent psychiatric services, with a particularly elevated likelihood among those with both suicide attempts and non-suicidal self-harm (OR = 9.3). This finding remained significant even when controlling for psychosocial variables. In adolescents with both suicide attempts and non-suicidal self-harm, symptoms of depression, eating problems, and the use of illicit drugs were associated with a higher likelihood of contact with child and adolescent psychiatric services, whereas a non-Western immigrant background was associated with a lower likelihood. In this study, adolescents who reported self-harm were significantly more likely than other adolescents to have used child and adolescent psychiatric services, and adolescents who reported a history of both suicide attempts and non-suicidal self-harm were more likely to have used such services, even after controlling for other psychosocial risk factors. In this high-risk subsample, various psychosocial problems increased the probability of contact with child and

WHAT IS KNOWN ABOUT THE SUBJECT?: Self-harm plays a function, commonly in the form of distress management. There has been little focussed exploration of how individuals who use self-harm to manage distress cope when prevented from self-harm in an inpatient environment and how staff respond to this issue. This paper uses the experiences of mental health staff to add to the existing knowledge that self-harm has a functional role and supports the notion that interventions for self-harm should focus on the origins of distress. It describes the potential consequences that focussing on prevention of self-harm as opposed to actually managing distress may have on service-users, how staff attempt to manage these consequences and factors that may impact on staff interventions to prevent further distress/harm. WHAT ARE THE IMPLICATIONS FOR PRACTICE?: The findings suggest that mental healthcare staff should aim to understand the function of self-harm, use this understanding to develop an individualized care plan with the aim of managing distress and identify barriers to the effectiveness of the interventions so they can be worked around. Introduction Literature describes self-harm as functional and meaningful. This creates difficulties for service-users detained in an inpatient environment where self-harm is prevented. Aim Mental healthcare staff were interviewed to build on existing evidence of issues with the prevention approach and explore, from a staff perspective, how self-harm prevention impacts on service-users, how they manage distress and how this impacts on staff and their approach to care. Methods Qualitative methods were used to allow unexpected themes to arise. Ten semi-structured interviews were carried out with mental healthcare staff and thematically analysed. Findings and discussion The findings provide new evidence on the benefits and limitations of the inpatient environment for individuals who self-harm. Findings indicate that being unable to self-harm can

Differentiating drugs by harm potential: the rational versus the feasible.

In an ideal harm reduction model, drugs would be ranked according to their potential to cause harm, with varying implications for control policies and interventions. In such a public health oriented approach, the maximum protection of the public from harm would be balanced with the least possible restriction of freedom. In reality, however, the accuracy and completeness of the necessary information for such a ranking is highly limited. Many other factors not readily incorporated in a rational model, such as values, beliefs, and traditions, also affect drug policy decisions. Thus, rather than relying on acquisition of the necessary knowledge, it may be preferable to focus efforts on developing effective nonlegal measures to reduce drug use and harm.

The US Food and Drug Administration (FDA) has regulatory authority to use inserts to communicate with consumers about harmful and potentially harmful constituents (HPHCs) in tobacco products; however, little is known about the most effective manner for presenting HPHC information. In a discrete choice experiment, participants evaluated eight choice sets, each of which showed two cigarette packages from four different brands and tar levels (high vs low), accompanied by an insert that included between-subject manipulations (ie, listing of HPHCs vs grouping by disease outcome and numeric values ascribed to HPHCs vs no numbers) and within-subject manipulations (ie, 1 of 4 warning topics; statement linking an HPHC with disease vs statement with no HPHC link). For each choice set, participants were asked: (1) which package is more harmful and (2) which motivates them to not smoke; each with a 'no difference' option. Alternative-specific logit models regressed choice on attribute levels. 1212 participants were recruited from an online consumer panel (725 18-29-year-old smokers and susceptible non-smokers and 487 30-64-year-old smokers). Participants were more likely to endorse high-tar products as more harmful than low-tar products, with a greater effect when numeric HPHC information was present. Compared with a simple warning statement, the statement linking HPHCs with disease encouraged quit motivation. Numeric HPHC information on inserts appears to produce misunderstandings that some cigarettes are less harmful than others. Furthermore, brief narratives that link HPHCs to smoking-related disease may promote cessation versus communications that do not explicitly link HPHCs to disease. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

To examine the methods of fatal self harm (FSH) used by the elderly compared to young adults. We compared the methods of FSH used by all the elderly over 60 years of age to those used by all younger adults, over 16 and under 60, in the city of Birmingham and Solihull over a period of 4 years, 1995-1998. We applied the term FSH to all deceased who were subjects of Coroner's inquests and attracted verdicts of suicide and open verdicts. A significantly higher proportion of the elderly who fatally harmed themselves did so by drowning and asphyxia compared to the younger age group (p suicide among elderly men and women were hanging and self-poisoning by overdose, respectively. The study shows that the most common method of suicide in the elderly is poisoning by drug overdose. It raises the question about the quantity of drugs prescribed for the elderly, e.g. antidepressants, sedatives and pain killers. The study did not confirm previous reports that violent methods are used more frequently with increasing age. Copyright 2000 John Wiley & Sons, Ltd.

Recent research on the patterns of self-harm around public holidays is lacking. This study used national data to examine the patterns of hospital-treated self-harm during public holidays, and to examine associated factors. Data on self-harm presentations to all emergency departments were obtained from the National Self-Harm Registry Ireland. The association between self-harm presentations and public holidays was examined using univariate and multivariate Poisson regression analyses. A total of 104,371 presentations of self-harm were recorded between 2007 and 2015. The mean number of self-harm presentations was 32 on public holidays. St. Patrick's Day had the highest number of presentations compared to all other public holidays, with a daily mean of 44 presentations. Across all years, self-harm presentations during public holidays had a 24% increased risk of involving alcohol consumption compared to all other days and this effect was most pronounced during the Christmas period. The association with alcohol remained significant at a multivariate level. Presentations on public holidays were more likely to attend out of normal working hours. An increase in male presentations involving self-cutting was observed on public holidays and there was an over-representation of males presenting for the first time. It is likely that extent of alcohol involvement in self-harm presentations reported here is an underestimate, as it was dependent on the information being recorded by the attending clinician. Public holidays are associated with an elevated number of self-harm presentations to hospital, with presentations to hospital involving alcohol significantly increased on these days. Hospital resources should be targeted to address increases during public holidays, including during out-of-hours. Involvement of alcohol may delay delivery of care to these patients in emergency settings. Copyright © 2017 Elsevier B.V. All rights reserved.

Harm reduction in U.S. tobacco control: Constructions in textual news media.

Science.gov (United States)

Eversman, Michael H

2015-06-01

U.S. tobacco control has long emphasized abstinence, yet quitting smoking is hard and cessation rates low. Tobacco harm reduction alternatives espouse substituting cigarettes with safer nicotine and tobacco products. Policy shifts embracing tobacco harm reduction have increased media attention, yet it remains controversial. Discourse theory posits language as fluid, and socially constructed meaning as neither absolute nor neutral, elevating certain views over others while depicting "discursive struggle" between them. While an abstinence-based framework dominates tobacco policy, discourse theory suggests constructions of nicotine and tobacco use can change, for example by positioning tobacco harm reduction more favorably. Textual discourse analysis was used to explore constructions of tobacco harm reduction in 478 (308 original) U.S. textual news media articles spanning 1996-2014. Using keyword database sampling, retrieved articles were analyzed first as discrete recording units and then to identify emergent thematic content. Constructions of tobacco harm reduction shifted over this time, revealing tension among industry and policy interests through competing definitions of tobacco harm reduction, depictions of its underlying science, and accounts of regulatory matters including tobacco industry support for harm reduction and desired marketing and taxation legislation. Heightened salience surrounding tobacco harm reduction and electronic cigarettes suggests their greater acceptance in U.S. tobacco control. Various media depictions construct harm reduction as a temporary means to cessation, and conflict with other constructions of it that place no subjective value on continued "safer" tobacco/nicotine use. Constructions of science largely obscure claims of the veracity of tobacco harm reduction, with conflict surrounding appropriate public health benchmarks for tobacco policy and health risks of nicotine use.

Will growth in cryptomarket drug buying increase the harms of illicit drugs?

Cryptomarkets-on-line, anonymous market-places for illicit goods and services that specialize mainly in drugs-account for a small but rapidly growing share of the illicit drug market in many countries. Policy responses so far are based generally on the assumption that their rise will only increase drug harms. In this contribution for debate, we question this assumption. We provide a narrative review of the emerging literature connected to drug cryptomarkets. We use MacCoun & Reuter's formula to understand the effect of population-level increases in use on total harm as depending on the level of harm associated with each unit of use. We then consider the potential for cryptomarkets to increase or decrease the harms and benefits related to each unit of drug use, with specific attention to the quality of drugs sold and the non-drug-related harms and benefits for customers. It is likely that cryptomarkets will increase both the amount and the range of substances that are sold. However, we argue that the effects on harms will depend upon whether cryptomarkets also increase the quality and safety of products that are sold, provide harm-reducing information to consumers and reduce transactional conflict involved in drug purchasing. There is an emerging and rapidly growing evidence base connected to the macro and micro harms and benefits of cryptomarkets for drug users. Future researchers should use appropriately matched comparative designs to establish more firmly the differential harms and benefits of sourcing drugs both on- and off-line. While it is unlikely that the on-line drug trade can be eradicated completely, cryptomarkets will respond to regulation and enforcement in ways that have complex, and sometimes unanticipated, effects on both harms and benefits. © 2017 The Authors.

The hyperintense acute reperfusion marker (HARM) on fluid-attenuated inversion recovery (FLAIR) images is associated with blood-brain barrier (BBB) permeability changes. The aim of this study was to examine the influence of contrast agent dosage on HARM incidence in acute ischaemic stroke patients. We prospectively included 529 acute ischaemic stroke patients (204 females, median age 71 years). Patients underwent a first stroke-MRI within 24 hours from symptom onset and had a follow-up on day 2. The contrast agent Gadobutrol was administered to the patients for perfusion imaging or MR angiography. The total dosage was calculated as ml/kg body weight and ranged between 0.04 and 0.31 mmol/kg on the first examination. The incidence of HARM was evaluated on day 2 FLAIR images. HARM was detected in 97 patients (18.3 %). HARM incidence increased significantly with increasing dosages of Gadobutrol. Also, HARM positive patients were significantly older. HARM was not an independent predictor of worse clinical outcome, and we did not find an association with increase risk of haemorrhagic transformation. A higher dosage of Gadobutrol in acute stroke patients on initial MRI is associated with increased HARM incidence on follow-up. MRI studies on BBB should therefore standardize contrast agent dosages.

Can Google Searches Predict the Popularity and Harm of Psychoactive Agents?

Jankowski, Wojciech; Hoffmann, Marcin

2016-02-25

Predicting the popularity of and harm caused by psychoactive agents is a serious problem that would be difficult to do by a single simple method. However, because of the growing number of drugs it is very important to provide a simple and fast tool for predicting some characteristics of these substances. We were inspired by the Google Flu Trends study on the activity of the influenza virus, which showed that influenza virus activity worldwide can be monitored based on queries entered into the Google search engine. Our aim was to propose a fast method for ranking the most popular and most harmful drugs based on easily available data gathered from the Internet. We used the Google search engine to acquire data for the ranking lists. Subsequently, using the resulting list and the frequency of hits for the respective psychoactive drugs combined with the word "harm" or "harmful", we estimated quickly how much harm is associated with each drug. We ranked the most popular and harmful psychoactive drugs. As we conducted the research over a period of several months, we noted that the relative popularity indexes tended to change depending on when we obtained them. This suggests that the data may be useful in monitoring changes over time in the use of each of these psychoactive agents. Our data correlate well with the results from a multicriteria decision analysis of drug harms in the United Kingdom. We showed that Google search data can be a valuable source of information to assess the popularity of and harm caused by psychoactive agents and may help in monitoring drug use trends.

Conceptual and methodological issues in studying alcohol’s harm to others

Room Robin

2016-12-01

Full Text Available While there is a longer history of concern about alcohol’s harm to others, researchers’ interest has intensified in the last few years. The background of variation in concern over time in different societies is outlined. Three main traditions of research have emerged: population survey studies of such harm from the perspective of the ‘other’; analysis of register or case-record data which includes information on the involvement of another’s drinking in the case; and qualitative studies of interactions and experiences involved in particular harms from others’ drinking. In the course of the new spate of studies, many conceptual and methodological issues have arisen, some of which are considered in the paper. The diverse types of harms which have been studied are discussed. The social and personal nature of many of the harms means they do not fit easily into a disability or costing model, raising questions about how they might best be counted and aggregated. Harm from others’ drinking is inherently interactional, and subject to varying definitions of what counts as harm. The attribution to drinking, in the usual situation of conditional causation, is also subject to variation, with moral politics potentially coming into play. For measurement and comparison, account needs to be taken of cultural and individual variations in perceptions and thresholds of what counts as a harm, and attribution to alcohol. The view from the windows of a population survey and of a response agency case register are often starkly different, and research is needed, as an input and spur to policy initiatives, on what influences this difference and whether and how the views might be reconciled.

Aim To reduce the incidence of self-harming behaviour and improve well-being and experience of care for individuals who present regularly to the emergency department in one hospital following self-harm, by providing outpatient care. Method This was a 12-month nurse-led practice development project to develop, implement and evaluate a brief-intervention outpatient service for individuals who presented to the emergency department following self-harm and who were identified as being at risk of further self-harm. The service improvement was informed by an action research process and the principles of appreciative inquiry. Findings The project provided a short-term outpatient follow-up service, known as Brief Interventions in Repeat Self Harm (BIRSH), to patients who presented to the emergency department following self-harm, and who were considered at risk of further self-harm. The intervention enabled the clinician to validate the patient's distress and offer them short-term outpatient follow-up care. The BIRSH sessions were offered to 38 patients. A total of 26 patients attended one or more BIRSH session, and all of these individuals showed a reduction in the number of presentations to the emergency department following self-harm in the six months following the intervention, compared to the six months before the intervention. Conclusion The BIRSH outpatient service appears to have been a contributory factor in reducing self-harm for patients who engaged with the service. The service improvement was informed by an action research process and the principles of appreciative inquiry, which provided a positive, focused approach to the practice development project.

Evolution of helping and harming in heterogeneous groups.

Rodrigues, António M M; Gardner, Andy

Social groups are often composed of individuals who differ in many respects. Theoretical studies on the evolution of helping and harming behaviors have largely focused upon genetic differences between individuals. However, nongenetic variation between group members is widespread in natural populations, and may mediate differences in individuals' social behavior. Here, we develop a framework to study how variation in individual quality mediates the evolution of unconditional and conditional social traits. We investigate the scope for the evolution of social traits that are conditional on the quality of the actor and/or recipients. We find that asymmetries in individual quality can lead to the evolution of plastic traits with different individuals expressing helping and harming traits within the same group. In this context, population viscosity can mediate the evolution of social traits, and local competition can promote both helping and harming behaviors. Furthermore, asymmetries in individual quality can lead to the evolution of competition-like traits between clonal individuals. Overall, we highlight the importance of asymmetries in individual quality, including differences in reproductive value and the ability to engage in successful social interactions, in mediating the evolution of helping and harming behaviors. © 2013 The Author(s).

Public health implications of smokeless tobacco use as a harm reduction strategy.

Science.gov (United States)

2006-11-01

Harm reduction strategies involve promoting a product that has adverse health consequences as a substitute for one that has more severe adverse health consequences. Smokeless tobacco low in nitrosamine content offers potential benefits in reducing smoking prevalence rates. Possible harm arises from the potential for such products to serve as a gateway to more harmful tobacco products, public misinterpretation of "less harmful" as "safe," distraction from the public health goal of tobacco elimination, and ethical issues involved in advising those marketing these harmful products. We offer a research agenda to provide a stronger basis for evaluating the risks and benefits of smokeless tobacco as a means of reducing the adverse health effects of tobacco.

Planned and unplanned acts of self-harm may have distinct clinical and psychological correlates. Trait impulsivity is one factor that might be expected to determine whether self-harm is planned. Research so far has focussed on suicide attempts and little is known about how individuals engaging in planned and unplanned acts of self-harm differ. The aim of the current study was to examine how individuals who report planned self-harm, unplanned self-harm, and no self-harm differ in terms of impulsivity and affective symptoms (depression, anxiety, and activated mood). An online survey of University students (n = 1350) was undertaken including measures of impulsivity, affective symptoms and self-harm. Analyses made use of a multinomial logistic regression model with affective and cognitive forms of impulsivity estimated as latent variables. Trait affective impulsivity, but not cognitive, was a general risk factor for whether self-harm occurred. There was no evidence of differences between planned and unplanned self-harm. Affective symptoms of depression and anxiety mediated the relationship between affective impulsivity and self-harm. The study was cross-sectional, relied on a student sample which may not generalise to other populations. Trait affective impulsivity is associated with self-harm but it appears to be mediated by depression and anxiety symptoms. The exact relationships between trait affective impulsivity, depression, anxiety and self-harm require further longitudinal research in clinical populations but might lead to improved risk assessment and new therapeutic approaches to self-harm.

Although a few studies investigated the impact of stock market fluctuations on population health, the question of whether stock market fluctuations have an impact on self-harm in children and adolescents remain unanswered. This study therefore investigated the association between stock market fluctuations and self-harm among children and adolescents in Hong Kong. Daily self-harm attendance records were retrieved from all 18 local Accident and Emergency Departments (AED) from 2001 to 2012. 4931 children and adolescents who committed self-harm were included. The results indicated positive correlation between daily change in stock market index, Hang Seng Index (∇HSI, per 300 points), and daily self-harm incident risk of children and adolescents, without time lag between the two. The incident risk ratio for ∇HSI was 1.09 ( p = 0.0339) in children and 1.06 ( p = 0.0246) in adolescents. Importantly, non-trading days were found to impose significant protective effect in both groups against self-harm risk. Our results showed that stock market fluctuations were related to self-harm behaviors in children and adolescents. Parents and professionals should be educated about the potential harm of stock market fluctuations and the importance of effective parenting in reducing self-harm among children and adolescents.

Replacement of harmful animal use in life science education: the approach and activities of InterNICHE.

Science.gov (United States)

Jukes, Nick

2004-06-01

Harmful animal use in undergraduate education is increasingly being replaced by alternatives, such as computer software, manikins and simulators, ethically sourced animal cadavers, apprentice work with animal patients, and student self-experimentation. Combinations of such alternatives can better meet teaching objectives, reduce costs and avoid the negative pedagogical and social impact of animal experimentation. Since 1988, the International Network for Humane Education (InterNICHE, formerly EuroNICHE) has been working with teachers to replace harmful animal use and has been supporting students' right to conscientious objection. This paper presents the approach, history and current activities of InterNICHE. With a vision of 100% replacement, the network aims for empowerment by networking information and providing support. It works with the belief that most teachers want investment in the best quality and most humane education possible. The forthcoming second edition of the InterNICHE book, from Guinea Pig to Computer Mouse,1 includes practical details of progressive teaching aids and approaches, as well as case studies from teachers who employ such alternatives. In 1999, InterNICHE produced the film Alternatives in Education, now available in 20 languages. Such resources are complemented by outreach trips and conferences and an Alternatives Loan System, which offers products for familiarisation and assessment. The InterNICHE website (www.interniche.org) was launched in 2001.

Non-suicidal reasons for self-harm: A systematic review of self-reported accounts.

Edmondson, Amanda J; Brennan, Cathy A; House, Allan O

2016-02-01

Self-harm is a major public health problem yet current healthcare provision is widely regarded as inadequate. One of the barriers to effective healthcare is the lack of a clear understanding of the functions self-harm may serve for the individual. The aim of this review is to identify first-hand accounts of the reasons for self-harm from the individual's perspective. A systematic review of the literature reporting first-hand accounts of the reasons for self-harm other than intent to die. A thematic analysis and 'best fit' framework synthesis was undertaken to classify the responses. The most widely researched non-suicidal reasons for self-harm were dealing with distress and exerting interpersonal influence. However, many first-hand accounts included reasons such as self-validation, and self-harm to achieve a personal sense of mastery, which suggests individuals thought there were positive or adaptive functions of the act not based only on its social effects. Associations with different sub-population characteristics or with the method of harm were not available from most studies included in the analysis. Our review identified a number of themes that are relatively neglected in discussions about self-harm, which we summarised as self-harm as a positiveexperience and defining the self. These self-reported "positive" reasons may be important in understanding and responding especially to repeated acts of self-harm. Copyright © 2016 The Authors. Published by Elsevier B.V.

The effect of healthcare delivery privatisation on avoidable mortality: longitudinal cross-regional results from Italy, 1993-2003.

2013-02-01

During the 1990s, Italy privatised a significant portion of its healthcare delivery. The authors compared the effectiveness of private and public sector healthcare delivery in reducing avoidable mortality (deaths that should not occur in the presence of effective medical care). The authors calculated the average rate of change in age-standardised avoidable mortality rates in 19 of Italy's regions from 1993 to 2003. Multivariate regression models were used to analyse the relationship between rates of change in avoidable mortality and levels of spending on public versus private healthcare delivery, controlling for potential demographic and economic confounders. Greater spending on public delivery of health services corresponded to faster reductions in avoidable mortality rates. Each €100 additional public spending per capita on NHS delivery was independently associated with a 1.47% reduction in the rate of avoidable mortality (p=0.003). In contrast, spending on private sector services had no statistically significant effect on avoidable mortality rates (p=0.557). A higher percentage of spending on private sector delivery was associated with higher rates of avoidable mortality (p=0.002). The authors found that neither public nor private sector delivery spending was significantly associated with non-avoidable mortality rates, plausibly because non-avoidable mortality is insensitive to healthcare services. Public spending was significantly associated with reductions in avoidable mortality rates over time, while greater private sector spending was not at the regional level in Italy.

Full Text Available Abstract Background Mitigating or reducing the risk of harm associated with the delivery of healthcare is a policy priority. While the risk of harm can be reduced in some instances (i.e. preventable, what constitutes preventable harm remains unclear. A standardized and clear definition of preventable harm is the first step towards safer and more efficient healthcare delivery system. We aimed to summarize the definitions of preventable harm and its conceptualization in healthcare. Methods We conducted a comprehensive electronic search of relevant databases from January 2001 to June 2011 for publications that reported a definition of preventable harm. Only English language publications were included. Definitions were coded for common concepts and themes. We included any study type, both original studies and reviews. Two reviewers screened the references for eligibility and 28% (127/460 were finally included. Data collected from studies included study type, description of the study population and setting, and data corresponding to the outcome of interest. Three reviewers extracted the data. The level of agreement between the reviewers was calculated. Results One hundred and twenty seven studies were eligible. The three most prevalent preventable harms in the included studies were: medication adverse events (33/127 studies, 26%, central line infections (7/127, 6% and venous thromboembolism (5/127, 4%. Seven themes or definitions for preventable harm were encountered. The top three were: presence of an identifiable modifiable cause (58/132 definitions, 44%, reasonable adaptation to a process will prevent future recurrence (30/132, 23%, adherence to guidelines (22/132, 16%. Data on the validity or operational characteristic (e.g., accuracy, reproducibility of definitions were limited. Conclusions There is limited empirical evidence of the validity and reliability of the available definitions of preventable harm, such that no single one is supported by

Harmful Freshwater Algal Blooms, With an Emphasis on Cyanobacteria

Directory of Open Access Journals (Sweden)

Hans W. Paerl

2001-01-01

Full Text Available Suspended algae, or phytoplankton, are the prime source of organic matter supporting food webs in freshwater ecosystems. Phytoplankton productivity is reliant on adequate nutrient supplies; however, increasing rates of nutrient supply, much of it manmade, fuels accelerating primary production or eutrophication. An obvious and problematic symptom of eutrophication is rapid growth and accumulations of phytoplankton, leading to discoloration of affected waters. These events are termed blooms. Blooms are a prime agent of water quality deterioration, including foul odors and tastes, deoxygenation of bottom waters (hypoxia and anoxia, toxicity, fish kills, and food web alterations. Toxins produced by blooms can adversely affect animal (including human health in waters used for recreational and drinking purposes. Numerous freshwater genera within the diverse phyla comprising the phytoplankton are capable of forming blooms; however, the blue-green algae (or cyanobacteria are the most notorious bloom formers. This is especially true for harmful toxic, surface-dwelling, scum-forming genera (e.g., Anabaena, Aphanizomenon, Nodularia, Microcystis and some subsurface bloom-formers (Cylindrospermopsis, Oscillatoria that are adept at exploiting nutrient-enriched conditions. They thrive in highly productive waters by being able to rapidly migrate between radiance-rich surface waters and nutrient-rich bottom waters. Furthermore, many harmful species are tolerant of extreme environmental conditions, including very high light levels, high temperatures, various degrees of desiccation, and periodic nutrient deprivation.

Methods: The study aimed to explore the attitudes of mental health nurses toward service users who self-harm in secure environments, and to inform mental health curriculum development. It was conducted in a large forensic mental health unit, containing medium and low secure facilities, to the west of London, UK. A qualitative multi-method approach was adopted, underpinned by interpretative phenomenological analysis. Data were obtained from mental health nurses using individual interviews and focus groups, and analysis followed a step-by-step thematic approach using interpretative phenomenological analysis. Results: Nurses' attitudes toward self-harm varied but were mainly negative, and this was usually related to limited knowledge and skills. The results of the study, framed by the Theory of Planned Behaviour, led to the development of a proposed educational model entitled ‘Factors Affecting Self-Harming Behaviours’ (FASH. Conclusion: The FASH Model may inform future curriculum innovation. Adopting a holistic approach to education of nurses about self-harm may assist in developing attitudes and skills to make care provision more effective in secure mental health settings.

Harmful situations, impure people: an attribution asymmetry across moral domains.

Science.gov (United States)

Chakroff, Alek; Young, Liane

2015-03-01

People make inferences about the actions of others, assessing whether an act is best explained by person-based versus situation-based accounts. Here we examine people's explanations for norm violations in different domains: harmful acts (e.g., assault) and impure acts (e.g., incest). Across four studies, we find evidence for an attribution asymmetry: people endorse more person-based attributions for impure versus harmful acts. This attribution asymmetry is partly explained by the abnormality of impure versus harmful acts, but not by differences in the moral wrongness or the statistical frequency of these acts. Finally, this asymmetry persists even when the situational factors that lead an agent to act impurely are stipulated. These results suggest that, relative to harmful acts, impure acts are linked to person-based attributions. Copyright © 2014 Elsevier B.V. All rights reserved.

Party drugs - use and harm reduction.

Science.gov (United States)

Frei, Matthew

2010-08-01

Party drug use, the intermittent use of stimulants, ecstasy and so-called 'designer drugs' at dance parties or 'raves', is now part of the culture of many young Australians. This article discusses the risks associated with the use of 'party drugs' and describes an useful approach to general practitioner assessment and management of patients who may be using party drugs. Party drug use is associated with a range of harms, including risks associated with behaviour while drug affected, toxicity and overdose, mental health complications and physical morbidity. Multiple substance use, particularly combining sedatives, further amplifies risk. If GPs have some understanding of these drugs and their effects, they are well placed to provide an effective intervention in party drug users by supporting the reduction of harm.

Full Text Available Avoidance behaviour test with the earthworms (ISO 17512-1:2008 is a rapid screening test for the evaluation of soil and the influence of pollutants and chemicals on the behaviour of earthworms. The purpose of the testing is to determine the avoidance behaviour of earthworm (in this case Eisenia andrei was used which can be used as an organism for the composting and occur naturally in soil environment. The methodology was modified according to the needs of the avoidance behaviour testing of earthworms in biodegradable plastic environment. It is a biodegradable thermoplastic material Mater-Bi, which is produced from corn starch. Californian earthworm (Eisenia andrei was chosen as a test organism. The two-chamber test was used in testing. 10 earthworms were used, which were exposed to a number of concentrations of the test substance, which was mixed into the compost environment. It was recorded both a positive result, avoidance reaction, as well as a negative result, non-avoidance reaction and also there was a case, where individuals prefer both substrates equally. Organisms showed no escape reaction and were fairly evenly distributed in both halves of the test vessel, it can be assessed that organisms prefer both substrates equally. In testing, the mortality was zero, none of the individuals died, at the conclusion of the test there were not found any dead individuals. Avoidance higher than 80 % didn’t occur; it cannot be said that the substrate is toxic or degraded.

BACKGROUND: One of the most important components of suicide prevention strategies is to target people who repeat self-harm as they are a high risk group. However, there is some evidence that the incidence of repeat self-harm is lower in Asia than in the West. The objective of this study...... was to investigate the prevalence of previous self-harm among a consecutive series of self-harm patients presenting to hospitals in rural Sri Lanka. METHOD: Six hundred and ninety-eight self-poisoning patients presenting to medical wards at two hospitals in Sri Lanka were interviewed about their previous episodes...... of self-harm. RESULTS: Sixty-one (8.7%, 95% CI 6.7-11%) patients reported at least one previous episode of self-harm [37 (10.7%) male, 24 (6.8%) female]; only 19 (2.7%, 95% CI 1.6-4.2%) patients had made more than one previous attempt. CONCLUSION: The low prevalence of previous self-harm is consistent...

Impact of Tactical and Strategic Weather Avoidance on Separation Assurance

Refai, Mohamad S.; Windhorst, Robert

2011-01-01

The ability to keep flights away from weather hazards while maintaining aircraft-to-aircraft separation is critically important. The Advanced Airspace Concept is an automation concept that implements a ground-based strategic conflict resolution algorithm for management of aircraft separation. The impact of dynamic and uncertain weather avoidance on this concept is investigated. A strategic weather rerouting system is integrated with the Advanced Airspace Concept, which also provides a tactical weather avoidance algorithm, in a fast time simulation of the Air Transportation System. Strategic weather rerouting is used to plan routes around weather in the 20 minute to two-hour time horizon. To address forecast uncertainty, flight routes are revised at 15 minute intervals. Tactical weather avoidance is used for short term trajectory adjustments (30 minute planning horizon) that are updated every minute to address any weather conflicts (instances where aircraft are predicted to pass through weather cells) that are left unresolved by strategic weather rerouting. The fast time simulation is used to assess the impact of tactical weather avoidance on the performance of automated conflict resolution as well as the impact of strategic weather rerouting on both conflict resolution and tactical weather avoidance. The results demonstrate that both tactical weather avoidance and strategic weather rerouting increase the algorithm complexity required to find aircraft conflict resolutions. Results also demonstrate that tactical weather avoidance is prone to higher airborne delay than strategic weather rerouting. Adding strategic weather rerouting to tactical weather avoidance reduces total airborne delays for the reported scenario by 18% and reduces the number of remaining weather violations by 13%. Finally, two features are identified that have proven important for strategic weather rerouting to realize these benefits; namely, the ability to revise reroutes and the use of maneuvers

Harm reduction and “Clean” community: can Viet Nam have both?

Full Text Available Abstract The findings of our research show that while police play multiple roles in the fight against drug-related crime, they often perceived their tasks – especially preventing and controlling drug use on the one hand, and supporting harm reduction on the other – as contradictory, and this creates tensions in their work and relations with their communities. Although they are leaders and implementers of harm reduction, not all police know about it, and some remain skeptical or perceive it as contradictory to their main task of fighting drugs. Methadone treatment is seen by some as in competition with their main task of coordinating conventional drug treatment in the rehabilitation center. The history of drug use and the evolution of discourses on drug use in Viet Nam have created these conflicting pressures on police, and thus created contradictory expectations and led to different views and attitudes of police regarding various harm reduction measures. This might aid understanding why, despite the comprehensive and progressive policies on HIV/AIDS and harm reduction in Viet Nam, it is not easy for police to actively and effectively support and be involved in harm reduction at the ground level. To promote the wider acceptance of harm reduction the concept of community safety must be expanded to include community health; harm reduction must be integrated into the “new society” movement; and laws and policies need further revision to reduce contradiction between current drug laws and HIV laws. Harm reduction guidelines for police and other actors need to be disseminated and supported, embodying better ways of working between sectors, and all sectors in the partnership require support for building capacity to contribute to the overall goal.

Self-harm and attempted suicide within inpatient psychiatric services: a review of the literature.

2012-08-01

Self harm is a major public health concern, yet there are considerable challenges in providing support for those who self harm within psychiatric inpatient services. This paper presents the first review of research into self harm within inpatient settings. Searches of the main electronic databases were conducted using key words for self harm and inpatient care. There was substantial variation in the rates of self-harm and attempted suicide between studies, but rates were highest on forensic wards. There was no evidence of differences in prevalence of self-harm between men and women; women, however, were at increased risk of attempting suicide. People were more likely to self-harm in private areas of the ward and in the evening hours, and often self-harmed in response to psychological distress, or elements of nursing care that restricted their freedom. Wards used a variety of strategies to prevent self-harm; however, there is little research into their effectiveness. © 2012 The Authors.

Di Rocco, Richard; Belanger, Cowan; Imre, István; Brown, Grant; Johnson, Nicholas S.

2014-01-01

Sea lamprey (Petromyzon marinus) avoid damage-released and predator chemosensory cues at night, but their response to these cues during the day is unknown. Here, we explored (i) whether sea lamprey avoid these cues during the day and (ii) the effect of water temperature on the avoidance of chemosensory alarm cues in two diurnal laboratory experiments. We hypothesized that daytime activity would be temperature-dependent and that only sea lamprey vulnerable to predation (i.e., not hiding) would behaviourally respond to chemosensory alarm cues. Ten groups of ten sea lamprey were exposed to one of a variety of potential chemosensory cues. The experiments were conducted over a range of temperatures to quantify the effect of temperature on avoidance behaviour. Consistent with our hypothesis, a higher proportion of animals were active during daytime as water temperature increased. Moving sea lamprey showed an avoidance response to 2-phenylethylamine (a compound found in mammalian urine) and human saliva once water temperatures had risen to mean (±SD) = 13.7 (±1.4) °C. Resting and hiding sea lamprey did not show an avoidance response to any of the experimental stimuli.

1998-09-01

Full Text Available Coal is on of the most important energy source and its significance will increase in a future. In Czech republic coal is except else widely used as a fuel for combustion in a small boilers (up to 50 kW. Low efficiency of the small boilers which is often below 50% together with high emissions of the harmful substances into near surroundings cause in average 40 – 70% of total local air pollution. The research was performed in a scope of the Grant no. 101/98/0820 of Grant Agency of Czech Republic was focused on quality of combustion process related to combustion efficiency and creation of harmful substances at combustion of domestic fuels. Experiments were performed to compare combustion of brown coal, clack coal, coke and black coal slurry. Extremely high creation of harmful substances (CO, NOX, solid particles and organic substances was measured when the black coal slurry was used as a fuel, measured in kg of emissions per GJ of burned fuel. Combustion of brown coal produced significant emissions of solid particles which bond harmful substances as metals, polyaromatic hydrocarbons and others together with high emissions of SO2 . Strong dependence between emissions of CO and low quality of combustion given by low combustion temperature, shortage of combustion air, not suitable design of after-combustion chamber and short duration of fuel presence in a combustion area was found out. Emissions of wide range of metals were investigated. The results of the research grant project describe and explain the combustion process and creation of harmful substances in small boilers plus give suggestions and recommendations leading to rational operation of the small boilers and lowering their negative impact to environment.

Relationships Between Social Anxiety and Smoking-Specific Experiential Avoidance.

Watson, Noreen L; Heffner, Jaimee L; McClure, Jennifer B; Bricker, Jonathan B

2017-01-01

Although social anxiety is associated with higher prevalence of smoking and lower cessation rates, little is known about the underlying mechanisms of these relationships. Research suggests that socially anxious smokers have higher levels of smoking-specific experiential avoidance and are inclined to smoke to avoid internal smoking cues. However, it is unknown which types of internal smoking cues they avoid. Thus, this study aimed to address this gap in the literature. Participants (N = 450) were adult smokers from a group-based trial for smoking cessation. Bivariate correlations and hierarchical linear regression models examined relationships between baseline levels of social anxiety and acceptance of internal smoking cues-physical sensations, emotions, and cognitions. Social anxiety was associated with lower levels of acceptance of thoughts, sensations, and emotions that cue smoking. After controlling for levels of nicotine dependence, depression, generalized anxiety, and posttraumatic stress disorder, social anxiety still explained unique variability in overall acceptance of internal smoking cues and in acceptance of physical sensations and emotions that serve as smoking cues. Social anxiety no longer explained unique variability in acceptance of thoughts that trigger smoking. Smokers with high levels of social anxiety are less accepting of internal smoking cues. For physical and emotional cues, this effect was independent of level of dependence and mental health comorbidity. Results help explain why smokers with social anxiety are less likely to quit and can inform the development of targeted cessation treatments for smokers with social anxiety.

Contrary to the "model minority" myth, growing research indicates that the rates of mental health problems among Asian Americans may be higher than initially assumed. This study seeks to add to the scant knowledge regarding the mental health of Asian American men by examining the role of masculine norms, coping and cultural values in predicting depression among this population (N=149). Results reveal that Asian American men who used avoidant coping strategies and endorsed the masculine norm Dominance reported higher levels of depressive symptoms. In contrast, endorsing Winning masculine norms was associated to lower levels of depressive symptoms. Findings suggest that adherence to masculine norms and avoidant coping strategies play a salient role in the mental health of Asian American men.

Cigarette tax avoidance and evasion.

Science.gov (United States)

Stehr, Mark

2005-03-01

Variation in state cigarette taxes provides incentives for tax avoidance through smuggling, legal border crossing to low tax jurisdictions, or Internet purchasing. When taxes rise, tax paid sales of cigarettes will decline both because consumption will decrease and because tax avoidance will increase. The key innovation of this paper is to compare cigarette sales data to cigarette consumption data from the Behavioral Risk Factor Surveillance System (BRFSS). I show that after subtracting percent changes in consumption, residual percent changes in sales are associated with state cigarette tax changes implying the existence of tax avoidance. I estimate that the tax avoidance response to tax changes is at least twice the consumption response and that tax avoidance accounted for up to 9.6% of sales between 1985 and 2001. Because of the increase in tax avoidance, tax paid sales data understate the level of smoking and overstate the drop in smoking. I also find that the level of legal border crossing was very low relative to other forms of tax avoidance. If states have strong preferences for smoking control, they must pair high cigarette taxes with effective policies to curb smuggling and other forms of tax avoidance or employ alternative policies such as counter-advertising and smoking restrictions.

Marzano, Lisa; Ciclitira, Karen; Adler, Joanna

2012-03-01

To further understanding of how health and correctional staff responses to self-harming behaviours influence prisoners and their subsequent actions. Participant-centred, qualitative methods were used to explore the complex and under-researched perspectives of self-harming male prisoners. Semi-structured interviews were conducted with 20 adult male prisoners who had engaged in repetitive, non-suicidal self-harm during their current prison sentence, or considered doing so. The interviews were analyzed drawing on principles of thematic analysis and discourse analysis. With some exceptions, prison officers, nurses, and doctors are portrayed by prisoners as being ill-prepared to deal with repetitive self-harm, often displaying actively hostile attitudes and behaviours. These findings underscore the need for appropriate training, support and supervision for staff working with self-harming prisoners. ©2011 The British Psychological Society.

Ferrari, Joseph R; Ozer, Bilge Uzun; Demir, Ayhan

2009-06-01

The authors examined the prevalence of chronic procrastination (decisional, avoidant, and arousal styles) as functions of demographic variables among 354 Turkish adults (148 men, 206 women; M age = 38.7 years, SD = 8.26 years). Prevalence analyses showed that among Turkish participants, 17.5% were indecisive procrastinators, 13.8% were avoidant procrastinators, and 14.7% were arousal procrastinators. Results did not yield significant differences for gender or age on any forms of procrastination, which is consistent with other international samples. However, significant differences emerged depending on the number of children such that Turkish adults who had more than 3 children claimed to be more indecisive than they claimed to be arousal or avoidant procrastinators. Respondents with less than a graduate degree reported higher rates of indecision than did respondents with at least a graduate degree.

2005-08-01

Staff in the emergency departments of hospitals are reported as being negative or ambivalent toward suicidal or self-harming individuals. According to the literature, these patients are subjected to stigmatization and lack of empathy. This phenomenon has been linked to a decreased quality of care offered to these individuals and to missing an important opportunity to prevent further suicidal behavior or repetition of deliberate self-harm. Also, protocols, proper guidelines and education for the emergency staff call for a revision and an implementation. In this paper, evidence suggesting staff attitudes toward suicidal and self-harming patients is reviewed. An overview of related issues such as clinical judgment, the use of scales and nurses' role is also included in this report.

Pearson, Jennifer; Xiao, Haijun; Stalgaitis, Carolyn; Vallone, Donna

2014-01-01

Objectives. We provided estimates of noncombustible tobacco product (electronic nicotine delivery systems [ENDS]; snus; chewing tobacco, dip, or snuff; and dissolvables) use among current and former smokers and examined harm perceptions of noncombustible tobacco products and reasons for their use. Methods. We assessed awareness of, prevalence of, purchase of, harm perceptions of, and reasons for using noncombustible tobacco products among 1487 current and former smokers from 8 US designated market areas. We used adjusted logistic regression to identify correlates of noncombustible tobacco product use. Results. Of the sample, 96% were aware of at least 1 noncombustible tobacco product, but only 33% had used and 21% had purchased one. Noncombustible tobacco product use was associated with being male, non-Hispanic White, younger, and more nicotine dependent. Respondents used noncombustible tobacco products to cut down or quit cigarettes, but only snus was associated with a higher likelihood of making a quit attempt. Users of noncombustible tobacco products, particularly ENDS, were most likely to endorse the product as less harmful than cigarettes. Conclusions. Smokers may use noncombustible tobacco products to cut down or quit smoking. However, noncombustible tobacco product use was not associated with a reduction in cigarettes per day or cessation.

Approach/avoidance in dreams.

Science.gov (United States)

Malcolm-Smith, Susan; Koopowitz, Sheri; Pantelis, Eleni; Solms, Mark

2012-03-01

The influential threat simulation theory (TST) asserts that dreaming yields adaptive advantage by providing a virtual environment in which threat-avoidance may be safely rehearsed. We have previously found the incidence of biologically threatening dreams to be around 20%, with successful threat avoidance occurring in approximately one-fifth of such dreams. TST asserts that threat avoidance is over-represented relative to other possible dream contents. To begin assessing this issue, we contrasted the incidence of 'avoidance' dreams with that of their opposite: 'approach' dreams. Because TST states that the threat-avoidance function is only fully activated in ecologically valid (biologically threatening) contexts, we also performed this contrast for populations living in both high- and low-threat environments. We find that 'approach' dreams are significantly more prevalent across both contexts. We suggest these results are more consistent with the view that dreaming is generated by reward-seeking systems than by fear-conditioning systems, although reward-seeking is clearly not the only factor determining the content of dreams.

2012-06-01

Attachment-related avoidance and anxiety have repeatedly been associated with poorer adjustment in various social, emotional, and behavioral domains. We examined 2 domains in which avoidant individuals might be better equipped than their less avoidant peers to succeed and be satisfied--professional singles tennis and computer science. These fields may reward self-reliance, independence, and the ability to work without proximal social support from loved ones. In study 1, we followed 58 professional singles tennis players for 16 months and found that scores on attachment-related avoidance predicted a higher ranking, above and beyond the contributions of training and coping resources. In study 2, we sampled 100 students and found that those who scored higher on avoidance were happier with their choice of computer science as a career than those who scored lower on avoidance. Results are discussed in relation to the possible adaptive functions of certain personality characteristics often viewed as undesirable. © 2011 The Authors.

Evaluations of alcohol policy changes demonstrate that restriction of trading hours of both 'on'- and 'off'-licence venues can be an effective means of reducing rates of alcohol-related harm. Despite this, the effects of different trading hour policy options over time, accounting for different contexts and demographic characteristics, and the common co-occurrence of other harm reduction strategies in trading hour policy initiatives, are difficult to estimate. The aim of this study was to use dynamic simulation modelling to compare estimated impacts over time of a range of trading hour policy options on various indicators of acute alcohol-related harm. An agent-based model of alcohol consumption in New South Wales, Australia was developed using existing research evidence, analysis of available data and a structured approach to incorporating expert opinion. Five policy scenarios were simulated, including restrictions to trading hours of on-licence venues and extensions to trading hours of bottle shops. The impact of the scenarios on four measures of alcohol-related harm were considered: total acute harms, alcohol-related violence, emergency department (ED) presentations and hospitalizations. Simulation of a 3 a.m. (rather than 5 a.m.) closing time resulted in an estimated 12.3 ± 2.4% reduction in total acute alcohol-related harms, a 7.9 ± 0.8% reduction in violence, an 11.9 ± 2.1% reduction in ED presentations and a 9.5 ± 1.8% reduction in hospitalizations. Further reductions were achieved simulating a 1 a.m. closing time, including a 17.5 ± 1.1% reduction in alcohol-related violence. Simulated extensions to bottle shop trading hours resulted in increases in rates of all four measures of harm, although most of the effects came from increasing operating hours from 10 p.m. to 11 p.m. An agent-based simulation model suggests that restricting trading hours of licensed venues reduces rates of alcohol-related harm and extending trading hours of bottle

Amorim, Mónica João Barros; Scott-Fordsmand, Janeck James

2012-01-01

Environmental effects of copper nanoparticles are little studied in terrestrial ecosystems. In the present article, the toxicity of copper nanoparticles (Cu-NP) on the enchytraeid Enchytraeus albidus is compared to the toxicity of a copper-salt (CuCl 2 ). The effect parameters studied were survival, reproductive output and avoidance behaviour. The results show that Cu-NP were more toxic to E. albidus than the same concentrations of the CuCl 2 -salt. The physic-chemical analysis of the particles indicated that only a small fraction was released as ions. Hence, the results indicated a nanoparticle-specific effect – lower reproductive output and higher avoidance. This was observed as 2–8 fold (significant) lower ECx values for Cu-NP (EC 50-reprod = 95 mg Cu/kg; EC 50-avoid = 241 mg Cu/kg) exposed organisms compared to CuCl 2 (EC 50-reprod = 251 mg Cu/kg; EC 50-avoid = 475 mg Cu/kg) exposed organisms. These results corroborate with a nanoparticle-specific effect. - Highlights: ► Enchytraeus albidus were exposed to Cu-salt and Cu nanoparticles (80 nm) in soil. ► Survival, reproduction and avoidance behaviour were assessed. ► Particles characterization indicated very small ion release. ► Cu nanoparticles toxicity was higher than Cu-salt for reproduction and avoidance. - Toxicity of Cu chloride salt and Cu nanoparticles to Enchytraeus albidus indicated higher toxicity of Cu-NP.

Healthcare avoidance: a critical review.

Byrne, Sharon K

2008-01-01

The purpose of this study is to provide a critical review and synthesis of theoretical and research literature documenting the impact of avoidance on healthcare behaviors, identify the factors that influence healthcare avoidance and delay in the adult population, and propose a direction for future research. The Theory of Reasoned Action, Theory of Planned Behavior, Theory of Care-Seeking Behavior, the Transtheoretical Model, and the Behavioral Model of Health Services Use/Utilization are utilized to elaborate on the context within which individual intention to engage in healthcare behaviors occurs. Research literature on the concept of healthcare avoidance obtained by using computerized searches of CINAHL, MEDLINE, PSYCH INFO, and HAPI databases, from 1995 to 2007, were reviewed. Studies were organized by professional disciplines. Healthcare avoidance is a common and highly variable experience. Multiple administrative, demographic, personal, and provider factors are related to healthcare avoidance, for example, distrust of providers and/or the science community, health beliefs, insurance status, or socioeconomic/income level. Although the concept is recognized by multiple disciplines, limited research studies address its impact on healthcare decision making. More systematic research is needed to determine correlates of healthcare avoidance. Such studies will help investigators identify patients at risk for avoidant behaviors and provide the basis for health-promoting interventions. Methodological challenges include identification of characteristics of individuals and environments that hinder healthcare behaviors, as well as, the complexity of measuring healthcare avoidance. Studies need to systematically explore the influence of avoidance behaviors on specific healthcare populations at risk.

Belief that a product is less harmful may increase use or prevent smoking cessation. Objective To determine the effect of altering advertisement features on smokers’ beliefs of the harm exposure from a PREP. Methods A Quest advertisement was digitally altered using computer software and presented to participants using web-based television recruitment contracted through a survey company. 500 current smokers completed demographic and smoking history questions, were randomised to view one of three advertisement conditions, then completed eight items assessing their beliefs of the harmfulness of the product. Advertisement conditions included the original, unaltered advertisement; a “red” condition where the cigarette packages were digitally altered to the colour red, implying increased harm potential; and a “no text” condition where all text was removed to reduce explicit product information. Polytomous logistic regression, using “incorrect,” “unsure” and “correct” as outcomes, and advertisement type and covariates as predictors, was used for analyses. Results Participants randomised to the “no text” advertisement were less likely to be incorrect in their beliefs that Quest cigarettes are lower in tar, less addictive, less likely to cause cancer, have fewer chemicals, healthier and make smoking safer. Conclusions Smokers can form false beliefs about the harmfulness of PREP products based on how the PREPs are marketed. Careful examination must be undertaken to provide empirical evidence to better formulate regulatory principles of PREP advertising. PMID:18768457

Rates of self-harm are high and have recently increased. This trend and the repetitive nature of self-harm pose a significant challenge to mental health services. To determine the efficacy of a structured group problem-solving skills training (PST) programme as an intervention approach for self-harm in addition to treatment as usual (TAU) as offered by mental health services. A total of 433 participants (aged 18-64 years) were randomly assigned to TAU plus PST or TAU alone. Assessments were carried out at baseline and at 6-week and 6-month follow-up and repeated hospital-treated self-harm was ascertained at 12-month follow-up. The treatment groups did not differ in rates of repeated self-harm at 6-week, 6-month and 12-month follow-up. Both treatment groups showed significant improvements in psychological and social functioning at follow-up. Only one measure (needing and receiving practical help from those closest to them) showed a positive treatment effect at 6-week (P = 0.004) and 6-month (P = 0.01) follow-up. Repetition was not associated with waiting time in the PST group. This brief intervention for self-harm is no more effective than treatment as usual. Further work is required to establish whether a modified, more intensive programme delivered sooner after the index episode would be effective.

Anxiety sensitivity (AS), defined as the extent to which individuals believe that anxiety-related sensations have harmful consequences, is associated with smoking processes and poorer clinical outcomes among trauma-exposed smokers. Yet the specific mechanisms underlying this association are unclear. Smoking-specific avoidance and inflexibility is a construct implicated in multiple manifestations of mood regulation that may underlie smoking behavior. The current study examined the explanatory role of smoking-specific avoidance and inflexibility in terms of the relation between AS and indices of smoking behavior among trauma-exposed smokers. The sample consisted of 217 treatment-seeking adult smokers (44% female; M age = 37.8; SD = 13.2; age range: 18-65 years), who were exposed to at least one lifetime Criterion A trauma event (Diagnostic and Statistical Manual of Mental Disorders [4th ed., text rev.; DSM-IV-TR] Criterion A for trauma exposure). Bootstrap analysis (5,000 re-samples) revealed that AS was indirectly related to the (a) number of cigarettes smoked per day, (b) number of years being a daily smoker, (c) number of failed quit attempts, and (d) heaviness of smoking index among trauma-exposed smokers through its relation with smoking-specific avoidance and inflexibility. These findings provide initial evidence suggesting that smoking-specific avoidance and inflexibility may be an important construct in better understanding AS-smoking relations among trauma-exposed smokers. Future work is needed to explore the extent to which smoking-specific avoidance and inflexibility account for relations between AS and other smoking processes (e.g., withdrawal, cessation outcome) in the context of trauma and smoking comorbidity. © The Author(s) 2015.

Clinicians' perceptions of screening benefits and harms influence their recommendations, which in turn shape patients' screening decisions. We sought to understand clinicians' perceptions of the benefits and harms of cancer screening by comparing 2 screening tests that differ in their balance of potential benefits to harms: colonoscopy, which results in net benefit for many adults, and prostate-specific antigen (PSA) testing, which may do more harm than good. In this cross-sectional study, 126 clinicians at 24 family/internal medicine practices completed surveys in which they listed and rated the magnitude of colonoscopy and PSA testing benefits and harms for a hypothetical 70-year-old male patient and then estimated the likelihood that these tests would cause harm and lengthen the life of 100 similar men in the next 10 years. We tested the hypothesis that the availability heuristic would explain the association of screening test to perceived likelihood of benefit/harm and a competing hypothesis that clinicians' gist of screening tests as good or bad would mediate this association. Clinicians perceived PSA testing to have a greater likelihood of harm and a lower likelihood of lengthening life relative to colonoscopy. Consistent with our gist hypothesis, these associations were mediated by clinicians' gist of screening (balance of perceived benefits to perceived harms). Generalizability beyond academic clinicians remains to be established. Targeting clinicians' gist of screening, for example through graphical displays that allow clinicians to make gist-based relative magnitude comparisons, may influence their risk perception and possibly reduce overrecommendation of screening. © The Author(s) 2015.

Drosophila larvae innately show light avoidance behavior. Compared with robust blue-light avoidance, larvae exhibit relatively weaker green-light responses. In our previous screening for genes involved in larval light avoidance, compared with control w(1118) larvae, larvae with γ-glutamyl transpeptidase 1 (Ggt-1) knockdown or Ggt-1 mutation were found to exhibit higher percentage of green-light avoidance which was mediated by Rhodopsin6 (Rh6) photoreceptors. However, their responses to blue light did not change significantly. By adjusting the expression level of Ggt-1 in different tissues, we found that Ggt-1 in malpighian tubules was both necessary and sufficient for green-light avoidance. Our results showed that glutamate levels were lower in Ggt-1 null mutants compared with controls. Feeding Ggt-1 null mutants glutamate can normalize green-light avoidance, indicating that high glutamate concentrations suppressed larval green-light avoidance. However, rather than directly, glutamate affected green-light avoidance indirectly through GABA, the level of which was also lower in Ggt-1 mutants compared with controls. Mutants in glutamate decarboxylase 1, which encodes GABA synthase, and knockdown lines of the GABAA receptor, both exhibit elevated levels of green-light avoidance. Thus, our results elucidate the neurobiological mechanisms mediating green-light avoidance, which was inhibited in wild-type larvae. © 2014 International Society for Neurochemistry.

Reactive Collision Avoidance Algorithm

Scharf, Daniel; Acikmese, Behcet; Ploen, Scott; Hadaegh, Fred

2010-01-01

The reactive collision avoidance (RCA) algorithm allows a spacecraft to find a fuel-optimal trajectory for avoiding an arbitrary number of colliding spacecraft in real time while accounting for acceleration limits. In addition to spacecraft, the technology can be used for vehicles that can accelerate in any direction, such as helicopters and submersibles. In contrast to existing, passive algorithms that simultaneously design trajectories for a cluster of vehicles working to achieve a common goal, RCA is implemented onboard spacecraft only when an imminent collision is detected, and then plans a collision avoidance maneuver for only that host vehicle, thus preventing a collision in an off-nominal situation for which passive algorithms cannot. An example scenario for such a situation might be when a spacecraft in the cluster is approaching another one, but enters safe mode and begins to drift. Functionally, the RCA detects colliding spacecraft, plans an evasion trajectory by solving the Evasion Trajectory Problem (ETP), and then recovers after the collision is avoided. A direct optimization approach was used to develop the algorithm so it can run in real time. In this innovation, a parameterized class of avoidance trajectories is specified, and then the optimal trajectory is found by searching over the parameters. The class of trajectories is selected as bang-off-bang as motivated by optimal control theory. That is, an avoiding spacecraft first applies full acceleration in a constant direction, then coasts, and finally applies full acceleration to stop. The parameter optimization problem can be solved offline and stored as a look-up table of values. Using a look-up table allows the algorithm to run in real time. Given a colliding spacecraft, the properties of the collision geometry serve as indices of the look-up table that gives the optimal trajectory. For multiple colliding spacecraft, the set of trajectories that avoid all spacecraft is rapidly searched on

As the reduction of public supports which are harmful to the environment is a major stake in terms of struggle against pollutions and greenhouse gases, this publication proposes a discussion of these subsidies which are still important in France despite recent improvements, notably regarding wastes and fuels. The author first discusses how these harmful subsidies are defined by international or research bodies. He outlines that some subsidies have been suppressed since 2013, that important reforms have been initiated, and that, however, the level of harmful subsidies remains high. Then, he discusses the necessary reconciliation of different objectives, and briefly evokes the German and Italian assessment examples

Patients and families report experiencing a multitude of harms from medical errors resulting in physical, emotional, and financial hardships. Little is known about the duration and nature of these harms and the type of support needed to promote patient and family healing after such events. We sought to describe the long-term impacts (LTIs) reported by patients and family members who experienced harmful medical events 5 or more years ago. We performed a content analysis on 32 interviews originally conducted with 72 patients or family members about their views of the factors contributing to their self-reported harmful event. Interviews selected occurred 5 or more years after the harmful event and were grouped by time since event, 5 to 9 years (22 interviews) or 10 or more years (10 interviews) for analysis. We analyzed these interviews targeting spontaneous references of ongoing impacts experienced by the participants. Participants collectively described the following four LTIs: psychological, social/behavioral, physical, and financial. Most cited psychological impacts with half-reporting ongoing anger and vivid memories. More than half reported ongoing physical impacts and one-third experienced ongoing financial impacts. Long-term social and behavioral impacts such as alterations in lifestyle, self-identity, and healthcare seeking behaviors were the most highly reported. These patients and families experienced many profound LTIs after their harmful medical event. For some, these impacts evolved into secondary harms ongoing 10 years and more after the event. Our results draw attention to the persistent impacts patients and families may experience long after harmful events and the need for future research to understand and support affected patients and families.

Bullying is defined as repeated negative actions involving a power differential, and intention to harm. There is limited research on harmful intention as a definitional component. This study explored the role of the perpetrator's harmful intention and the target's perception of harmful intention. Some 209 students (M = 14.5 years; 66.5% female) and 447 parents (M = 46.4 years; 86.4% female) were randomly assigned in an online survey. Participants assessed the likelihood of bullying in five hypothetical scenarios (physical, verbal, rumor, exclusion, and cyber) across five intention conditions, that also involved repetition and a power differential. The five intention conditions were: 1) harm intended by perpetrator (I) and perceived as intended to harm by target (I) [II condition]; 2) harm not intended by perpetrator (N) but perceived as intended to harm by target (I) [NI condition]; 3) harm intended by perpetrator (I) but not perceived as intended to harm by target (N) [IN condition]; 4) harm not intended by perpetrator (N) and not perceived as intended to harm by target N [NN condition]; and 5) a control which did not state any actual or perceived harmful intention [C condition]. For students and parents, the perpetrator's harmful intention and the target's perception of harmful intention were important when considering whether a peer interaction constituted bullying. These findings confirm the applicability of the three-part definition of bullying, and highlight the importance of assessing these two dimensions of harmful intention when determining whether a problematic peer interaction should be regarded as bullying.

Harm reduction is a new paradigm that seeks to reduce the harmful consequences of substance use and other risky behaviors without requiring abstinence. This article discusses integrative harm reduction psychotherapy, one application of harm reduction principles to psychotherapy. Seven therapeutic tasks are described with attention to clinical process, skills, and strategies. A case is presented that illustrates the application of this approach with life-threatening substance use that was related to multiple trauma and suicidal depression.

To examine cigarette purchasing patterns of current smokers and to determine the effects of cigarette price on use of cheaper sources, discount/generic cigarettes, and coupons. Higher cigarette prices result in decreased cigarette consumption, but price sensitive smokers may seek lower priced or tax-free cigarette sources, especially if they are readily available. This price avoidance behaviour costs states excise tax money and dampens the health impact of higher cigarette prices. Telephone survey data from 3602 US smokers who were originally in the COMMIT (community intervention trial for smoking cessation) study were analysed to assess cigarette purchase patterns, use of discount/generic cigarettes, and use of coupons. 59% reported engaging in a high price avoidance strategy, including 34% who regularly purchase from a low or untaxed venue, 28% who smoke a discount/generic cigarette brand, and 18% who report using cigarette coupons more frequently that they did five years ago. The report of engaging in a price avoidance strategy was associated with living within 40 miles of a state or Indian reservation with lower cigarette excise taxes, higher average cigarette consumption, white, non-Hispanic race/ethnicity, and female sex. Data from this study indicate that most smokers are price sensitive and seek out measures to purchase less expensive cigarettes, which may decrease future cessation efforts.

[Harm reduction interventions in drug users: current situation and recommendations].

Harm reduction encompasses interventions, programmes and policies that seek to reduce the negative consequences of the consumption of both legal and illegal drugs on the individual and public health. Harm reduction looks to mitigate the harm suffered by drug users through drug use monitoring and prevention, and promotes initiatives that respect and protect the human rights of this population. The harm reduction policies that have proven effective and efficient are: opioid substitution maintenance therapy (methadone); needle and syringe exchange programmes; supervised drug consumption rooms; and overdose prevention through peer-based naloxone distribution. In order to be effective, these policies must have comprehensive coverage and be implemented in areas where the target population is prevalent. Resident-based opposition to the implementation of these policies is known as the NIMBY (Not In My Back Yard) phenomenon, which is characterised by being against the implementation of new measures in a particular place, but does not question their usefulness. Given that any NIMBY phenomenon is a complex social, cultural and political phenomenon, it is important to conduct a thorough analysis of the situation prior to implementing any of these measures. Harm reduction policies must be extended to other substances such as alcohol and tobacco, as well as to other conditions beyond infectious/contagious diseases and overdose. Copyright © 2016 SESPAS.

Franck, Caroline; Filion, Kristian B; Kimmelman, Jonathan; Grad, Roland; Eisenberg, Mark J

Due to their similarity to tobacco cigarettes, electronic cigarettes (e-cigarettes) could play an important role in tobacco harm reduction. However, the public health community remains divided concerning the appropriateness of endorsing a device whose safety and efficacy for smoking cessation remain unclear. We identified the major ethical considerations surrounding the use of e-cigarettes for tobacco harm reduction, including product safety, efficacy for smoking cessation and reduction, use among non-smokers, use among youth, marketing and advertisement, use in public places, renormalization of a smoking culture, and market ownership. Overall, the safety profile of e-cigarettes is unlikely to warrant serious public health concerns, particularly given the known adverse health effects associated with tobacco cigarettes. As a result, it is unlikely that the population-level harms resulting from e-cigarette uptake among non-smokers would overshadow the public health gains obtained from tobacco harm reduction among current smokers. While the existence of a gateway effect for youth remains uncertain, e-cigarette use in this population should be discouraged. Similarly, marketing and advertisement should remain aligned with the degree of known product risk and should be targeted to current smokers. Overall, the available evidence supports the cautionary implementation of harm reduction interventions aimed at promoting e-cigarettes as attractive and competitive alternatives to cigarette smoking, while taking measures to protect vulnerable groups and individuals.

The Unifying Moral Dyad: Liberals and Conservatives Share the Same Harm-Based Moral Template.

Schein, Chelsea; Gray, Kurt

2015-08-01

Do moral disagreements regarding specific issues (e.g., patriotism, chastity) reflect deep cognitive differences (i.e., distinct cognitive mechanisms) between liberals and conservatives? Dyadic morality suggests that the answer is "no." Despite moral diversity, we reveal that moral cognition--in both liberals and conservatives--is rooted in a harm-based template. A dyadic template suggests that harm should be central within moral cognition, an idea tested--and confirmed--through six specific hypotheses. Studies suggest that moral judgment occurs via dyadic comparison, in which counter-normative acts are compared with a prototype of harm. Dyadic comparison explains why harm is the most accessible and important of moral content, why harm organizes--and overlaps with--diverse moral content, and why harm best translates across moral content. Dyadic morality suggests that various moral content (e.g., loyalty, purity) are varieties of perceived harm and that past research has substantially exaggerated moral differences between liberals and conservatives. © 2015 by the Society for Personality and Social Psychology, Inc.

Harm reduction and viral hepatitis C in European prisons: a cross-sectional survey of 25 countries.

Current estimates suggest that 15% of all prisoners worldwide are chronically infected with the hepatitis C virus (HCV), and this number is even higher in regions with high rates of injecting drug use. Although harm reduction services such as opioid substitution therapy (OST) and needle and syringe programs (NSPs) are effective in preventing the further spread of HCV and HIV, the extent to which these are available in prisons varies significantly across countries. The Hep-CORE study surveyed liver patient groups from 25 European countries in 2016 and mid-2017 on national policies related to harm reduction, testing/screening, and treatment for HCV in prison settings. Results from the cross-sectional survey were compared to the data from available reports and the peer-reviewed literature to determine the overall degree to which European countries implement evidence-based HCV recommendations in prison settings. Patient groups in nine countries (36%) identified prisoners as a high-risk population target for HCV testing/screening. Twenty-one countries (84%) provide HCV treatment in prisons. However, the extent of coverage of these treatment programs varies widely. Two countries (8%) have NSPs officially available in prisons in all parts of the country. Eleven countries (44%) provide OST in prisons in all parts of the country without additional requirements. Despite the existence of evidence-based recommendations, infectious disease prevention measures such as harm reduction programs are inadequate in European prison settings. Harm reduction, HCV testing/screening, and treatment should be scaled up in prison settings in order to progress towards eliminating HCV as a public health threat.

Effect of soil moisture on sulphur accumulation in overground plant organs and their harm in emmission conditions

The effect of different soil moisture on sulphur accumulation in the overground organs of Fagopyrum esculentum, moench in immission conditions is dealt with in this paper. The results obtained have shown that even under equal soil conditions, equal nutrient supply and age evenness of the analyzed material the total sulphur content of leaves grown in immission conditions (sulphur oxides, hydrogen sulphide, carbon disulphide, etc.) at equal soil moisture was essentially higher when compared with unirrigated plants and corresponded also to the degree of harm and crop reduction of the experimental plants. Therefore it is necessary when utilizing sulphur content of indicating plants, which serves for a large-area diagnosis of vegetation harm with immissions, to take into consideration, in addition to other factors (soil, nutrition, age of plants), the soil moisture as well.

Household Factors Associated with Self-Harm in Johannesburg, South African Urban-Poor Households.

Full Text Available Low and middle income countries bear the majority burden of self-harm, yet there is a paucity of evidence detailing risk-factors for self-harm in these populations. This study aims to identify environmental, socio-economic and demographic household-level risk factors for self-harm in five impoverished urban communities in Johannesburg, South Africa.Annual serial cross-sectional surveys were undertaken in five impoverished urban communities in Johannesburg for the Health, Environment and Development (HEAD study. Logistic regression analysis using the HEAD study data (2006-2011 was conducted to identify household-level risk factors associated with self-harm (defined as a self-reported case of a fatal or non-fatal suicide attempt within the household during the preceding year. Stepwise multivariate logistic regression analysis was employed to identify factors associated with self-harm.A total of 2 795 household interviews were conducted from 2006 to 2011. There was no significant trend in self-harm over time. Results from the final model showed that self-harm was significantly associated with households exposed to a violent crime during the past year (Adjusted Odds Ratio (AOR 5.72; 95% CI 1.64-19.97; that have a member suffering from a chronic medical condition (AOR 8.95; 95% 2.39-33.56 and households exposed to indoor smoking (AOR 4.39; CI 95% 1.14-16.47.This study provides evidence on household risk factors of self-harm in settings of urban poverty and has highlighted the potential for a more cost-effective approach to identifying those at risk of self-harm based on household level factors.

This study tested whether exposure to e-cigarette advertising increases e-cigarette use susceptibility among non-smoking young adults by promoting explicit and implicit attitudes towards e-cigarettes as a safer and healthier alternative to combustible cigarettes. Young adult current non-smokers who had never used an e-cigarette (N = 393; Mean age = 22.1, Standard Deviation = 3.9; 66% Women) were randomly assigned to one of the 3 conditions that involved viewing real-world, print e-cigarette ads. Two of the 3 conditions were experimental conditions where ads with different predominant themes [harm-reduction ("Health") vs. social enhancement ("Social") focused] were interspersed among ads of everyday objects. The third condition was the control condition involving ads of everyday objects only. Participants provided data on explicit (i.e., self-reported harm perceptions) and implicit (i.e., Implicit Association Test) attitudes towards e-cigarette use and e-cigarette use intentions. Hypotheses were tested using structural equation modeling. Relative to Control participants, participants in Health and Social conditions were more likely to show higher implicit attitudes towards e-cigarettes as a safer alternative to cigarettes. Only the Social condition, relative to Control, had a significant effect on lower explicit harm perceptions of e-cigarette versus cigarette use. The Social condition had a significant indirect effect on e-cigarette use susceptibility, mediated by explicit harm perceptions. Social enhancement-themed ads may communicate the reduced-harm messages more strongly among young adults so as to affect both explicit and implicit attitudes and, through these, e-cigarette use susceptibility. Regulatory bodies may need to scrutinize reduced-harm claims communicated through social enhancement-themed ads. © The Author(s) 2018.

Children's Intrinsic Motivation to Provide Help Themselves After Accidentally Harming Others.

Science.gov (United States)

Hepach, Robert; Vaish, Amrisha; Tomasello, Michael

2017-07-01

Little is known about the flexibility of children's prosocial motivation. Here, 2- and 3-year-old children's (n = 128) internal arousal, as measured via changes in pupil dilation, was increased after they accidentally harmed a victim but were unable to repair the harm. If they were able to repair (or if they themselves did not cause the harm and the help was provided by someone else) their arousal subsided. This suggests that children are especially motivated to help those whom they have harmed, perhaps out of a sense of guilt and a desire to reconcile with them. Young children care not only about the well-being of others but also about the relationship they have with those who depend on their help. © 2016 The Authors.

Local competition increases people’s willingness to harm others

DEFF Research Database (Denmark)

Barker, Jessie; Barclay, Pat

2016-01-01

Why should organisms incur a cost in order to inflict a (usually greater) cost on others? Such costly harming behavior may be favored when competition for resources occurs locally, because it increases individuals' fitness relative to close competitors.

We found that, as predicted, people were more harmful to others when competition was local (study 1...

"Just Advil": Harm reduction and identity construction in the consumption of over-the-counter medication for chronic pain.

2015-12-01

Direct-to-consumer marketing has sparked ongoing debate concerning whether ads empower consumers to be agents of their own care or shift greater control to the pharmaceutical industry. Ads for over-the-counter (OTC) medications in particular portend to offer simple, harmless solutions for meeting the demands of social life. Rather than join the longstanding debate between consumer agency and social control in pharmaceutical advertising, I approach self-medication with over-the-counter (OTC) analgesics using Harm Reduction as a framework. From this perspective, consumption of OTC analgesics by chronic pain sufferers is a means of seeking some level of relief while also avoiding the stigma associated with prescription pain medication. Qualitative methods are used to analyze data from two sources: (1) semi-structured qualitative interviews with 95 participants in a trial examining the effectiveness of Traditional Chinese Medicine for Temporomandibular Disorders (TMD) from 2006 to 2011 in Tucson, AZ and Portland, OR; and (2) print, online, and television advertisements for three major brands of OTC pain medication. Participants described their use of OTC medications as minimal, responsible, and justified by the severity of their pain. OTC medication advertising, while ostensibly ambiguous and targeting all forms of pain, effectively lends support to the consumption of these medications as part of the self-projects of chronic pain sufferers, allowing them to reconcile conflicting demands for pain relief while being stoic and maintaining a positive moral identity. Describing OTC medication as "just over-the-counter" or "not real pain medication," sufferers engage in ideological harm reduction, distinguishing themselves from "those people who like taking pain medication" while still seeking relief. Justifying one's use of OTC medication as minimal and "normal," regardless of intake, avoids association with the addictive potential of prescription pain medications and

We present an update on our research on collision avoidance using photon-pressure induced by ground-based lasers. In the past, we have shown the general feasibility of employing small orbit perturbations, induced by photon pressure from ground-based laser illumination, for collision avoidance in space. Possible applications would be protecting space assets from impacts with debris and stabilizing the orbital debris environment. Focusing on collision avoidance rather than de-orbit, the scheme avoids some of the security and liability implications of active debris removal, and requires less sophisticated hardware than laser ablation. In earlier research we concluded that one ground based system consisting of a 10 kW class laser, directed by a 1.5 m telescope with adaptive optics, could avoid a significant fraction of debris-debris collisions in low Earth orbit. This paper describes our recent efforts, which include refining our original analysis, employing higher fidelity simulations and performing experimental tracking tests. We investigate the efficacy of one or more laser ground stations for debris-debris collision avoidance and satellite protection using simulations to investigate multiple case studies. The approach includes modeling of laser beam propagation through the atmosphere, the debris environment (including actual trajectories and physical parameters), laser facility operations, and simulations of the resulting photon pressure. We also present the results of experimental laser debris tracking tests. These tests track potential targets of a first technical demonstration and quantify the achievable tracking performance.

Modification of CO2 avoidance behaviour in Drosophila by inhibitory odorants.

Science.gov (United States)

Turner, Stephanie Lynn; Ray, Anandasankar

2009-09-10

The fruitfly Drosophila melanogaster exhibits a robust and innate olfactory-based avoidance behaviour to CO(2), a component of odour emitted from stressed flies. Specialized neurons in the antenna and a dedicated neuronal circuit in the higher olfactory system mediate CO(2) detection and avoidance. However, fruitflies need to overcome this avoidance response in some environments that contain CO(2) such as ripening fruits and fermenting yeast, which are essential food sources. Very little is known about the molecular and neuronal basis of this unique, context-dependent modification of innate olfactory avoidance behaviour. Here we identify a new class of odorants present in food that directly inhibit CO(2)-sensitive neurons in the antenna. Using an in vivo expression system we establish that the odorants act on the Gr21a/Gr63a CO(2) receptor. The presence of these odorants significantly and specifically reduces CO(2)-mediated avoidance behaviour, as well as avoidance mediated by 'Drosophila stress odour'. We propose a model in which behavioural avoidance to CO(2) is directly influenced by inhibitory interactions of the novel odours with CO(2) receptors. Furthermore, we observe differences in the temporal dynamics of inhibition: the effect of one of these odorants lasts several minutes beyond the initial exposure. Notably, animals that have been briefly pre-exposed to this odorant do not respond to the CO(2) avoidance cue even after the odorant is no longer present. We also show that related odorants are effective inhibitors of the CO(2) response in Culex mosquitoes that transmit West Nile fever and filariasis. Our findings have broader implications in highlighting the important role of inhibitory odorants in olfactory coding, and in their potential to disrupt CO(2)-mediated host-seeking behaviour in disease-carrying insects like mosquitoes.

Harming ourselves and defiling others: what determines a moral domain?

Directory of Open Access Journals (Sweden)

Alek Chakroff

Full Text Available Recent work has distinguished "harm" from "purity" violations, but how does an act get classified as belonging to a domain in the first place? We demonstrate the impact of not only the kind of action (e.g., harmful versus impure but also its target (e.g., oneself versus another. Across two experiments, common signatures of harm and purity tracked with other-directed and self-directed actions, respectively. First, participants judged self-directed acts as primarily impure and other-directed acts as primarily harmful. Second, conservatism predicted harsher judgments of self-directed but not other-directed acts. Third, while participants delivered harsher judgments of intentional versus accidental acts, this effect was smaller for self-directed than other-directed acts. Finally, participants judged self-directed acts more harshly when focusing on the actor's character versus the action itself; other-directed acts elicited the opposite pattern. These findings suggest that moral domains are defined not only by the kind of action but also by the target of the action.

Measuring Patients’ Attachment Avoidance in Psychotherapy: Development of the Attachment Avoidance in Therapy Scale (AATS

2012-11-01

Full Text Available A new scale measuring patient-therapist attachment avoidance was developed. Attachment Avoidance in Therapy Scale is a new measure based on the Bartholomew model of adult attachment (Bartholomew & Horowitz, 1991 and the Experience in Close Relationships Scale (Brennan, Clark, & Shaver, 1998 to measure patients’ attachment avoidance towards therapists. With 112 patient-therapist dyads participating in the study, validation of a preliminary scale – measuring both attachment anxiety and attachment avoidance in therapy – took place using therapists’ evaluations of patients’ relational behavior and patients’ self-reports about their attitude toward psychotherapy. Analysis of the data revealed six underlying scales. Results showed all six scales to be reliable. Validation of scales measuring attachment anxiety failed. The importance of Attachment Avoidance in Therapy Scale and its subscales is discussed.

Virtue ethics as an alternative to deontological and consequential reasoning in the harm reduction debate.

Science.gov (United States)

Christie, Timothy; Groarke, Louis; Sweet, William

2008-02-01

There is strong evidence that harm reduction interventions such as Supervised Injection Sites and Needle Exchange Programs prevent many of the negative consequences of problematic substance use. Yet many governments, including the United States and Canada, still do not endorse these interventions, claiming that they do not get people off of drugs and send a mixed message. This paper will analyze objections to harm reduction in light of the ethical theories of John Stuart Mill, Immanuel Kant and Aristotle. The most important ethical issue in the abstinence vs. harm reduction debate is whether harm reduction - because it does not require individuals to either reduce their consumption of illicit substances or to abstain from illicit substance use - can be ethically justified. Harm reduction interventions are clearly justified on Utilitarian grounds because, based on the evidence, such policies would produce the greatest good for the greatest number. However, Kant would not think that the values guiding harm reduction are ethical because the justification of harm reduction interventions focuses exclusively on examining consequences. Virtue Ethics seeks to find the proper balance between harm reduction and abstinence. We claim that the virtue of compassion would provide a defense of harm reduction.

A safer alternative: Cannabis substitution as harm reduction.

Substitution is operationalised as a conscious choice made by users to use one drug instead of, or in conjunction with another based on: perceived safety, level of addiction potential, effectiveness in relieving symptoms, access and level of acceptance. Harm reduction is a set of strategies that aim to minimise problems associated with drug use while recognising that for some users, abstinence may be neither a realistic nor a desirable goal. In this paper, we aim for deeper understandings of older adult cannabis users' beliefs and substitution practices as part of the harm reduction framework. We present selected findings from our qualitative study of Baby Boomer (born 1946-1964) marijuana users in the San Francisco Bay Area. Although the sample consisted of primary cannabis users, many had personal experience with other drugs throughout their lifetimes. Data collection consisted of an audio-recorded, semi-structured in-depth life history interview followed by a questionnaire and health survey. Qualitative interviews were analysed to discover users' harm reduction beliefs and cannabis substitution practices. Study participants described using cannabis as a safer alternative for alcohol, illicit drugs and pharmaceuticals based on their perceptions of less adverse side effects, low-risk for addiction and greater effectiveness at relieving symptoms, such as chronic pain. Cannabis substitution can be an effective harm reduction method for those who are unable or unwilling to stop using drugs completely. More research is needed on cannabis as a safer alternative. © 2015 Australasian Professional Society on Alcohol and other Drugs.

Personality Traits and Comorbidity in Adults With ADHD.

2016-10-01

To assess personality traits using the Temperament and Character Inventory (TCI) in a group of 63 previously diagnosed ADHD patients and 68 population controls and investigate the impact of common comorbid psychiatric disorders on these personality measures. Psychiatric comorbidity was assessed with the Mini International Neuropsychiatric Interview Plus and personality traits by the TCI. The patient group had significantly higher scores on the TCI dimensions Harm avoidance and Novelty seeking compared with the control group. However, when adjusting for comorbid anxiety and depressive disorder, the ADHD group no longer showed higher Harm avoidance than the control group. The difference in Novelty seeking between the patient and control groups was correlated with lifetime diagnosis of antisocial personality disorder (ASPD). It is important to take comorbid psychiatric disorders into account while investigating personality traits in ADHD. © The Author(s) 2013.

Drug misuse and abuse are major health problems. Harmful drugs are regulated according to classification systems that purport to relate to the harms and risks of each drug. However, the methodology and processes underlying classification systems are generally neither specified nor transparent, which reduces confidence in their accuracy and undermines health education messages. We developed and explored the feasibility of the use of a nine-category matrix of harm, with an expert delphic procedure, to assess the harms of a range of illicit drugs in an evidence-based fashion. We also included five legal drugs of misuse (alcohol, khat, solvents, alkyl nitrites, and tobacco) and one that has since been classified (ketamine) for reference. The process proved practicable, and yielded roughly similar scores and rankings of drug harm when used by two separate groups of experts. The ranking of drugs produced by our assessment of harm differed from those used by current regulatory systems. Our methodology offers a systematic framework and process that could be used by national and international regulatory bodies to assess the harm of current and future drugs of abuse.

The concept of "harm" in Internet gaming disorder.

Science.gov (United States)

King, Daniel L; Delfabbro, Paul H

2018-05-23

Internet gaming disorder (IGD) is a proposed condition that refers to persistent gaming leading to clinically significant impairment. However, there have been few attempts to study the different types and degrees of harm caused by IGD. This commentary describes some of the negative intrapersonal and interpersonal effects of an extreme time investment in gaming activities in the context of IGD. Future research should examine the way in which IGD harms may occur at different levels and degrees. This may enhance the screening of individuals whose behavior is suspected to meet the definition of the proposed IGD criteria.

Although the role of companion animals within the dynamic of domestic violence (DV) is increasingly recognized, the overlap of animal harm and insurance discrimination for victims/survivors of DV has not been considered. Prompted by a case study presented in a National Link Coalition LINK-Letter, this research note examines "Pet Insurance" policies available in Australia and whether nonaccidental injury caused by an intimate partner would be covered. We discuss the implications of exclusion criteria for victims/survivors of DV, shelters providing places for animals within a DV dynamic, and, more broadly, for cross- or mandatory-reporting (of animal harm) initiatives.

There is a significant overlap between non-suicidal self-harm and suicidal ideation and behavior in young people with both symptom continuity and symptom duration implicated in this association. A population sample of Australian 12-17 year olds. Interviewers collected measures for DSM disorders, symptom duration and continuity, and background information from their parents, while young people self-reported symptoms of depression, non-suicidal self-harm and suicidal ideation and behaviors. This report focusses on the 265 young people who met the DSM criteria for Major Depressive Disorder based on their own self-reports. Relative to young people who had at least one period 2 months or longer without symptoms since first onset, young people who had the continuous presence of depressive symptoms since their first onset had significantly higher odds for life-time self-harm, 12-month self-harm, multiple self-harm, suicidal ideation and suicide attempt within the past 12 months. The duration of depressive symptoms and the continuity of these symptoms each independently contribute to elevating the risks of non-suicidal self-harming and suicidal ideation and behaviors. Reliance on self-report from the young people and time constraints prohibiting administering diagnostic modules other than the Major Depressive Disorder and estimating self-reported co-morbidity. Among young people with a Major Depressive Disorder, self-reports about duration of depressive symptoms as well as the continuity of symptoms, each independently contributes to elevated risks of non-suicidal self-harming and suicidal ideation and behaviors. As well, un-remitting as opposed to episodic symptoms in this group of young people are common and are a powerful indicator of suffering associated with both self-harm and suicidal behavior.

A meta-analysis of fear-avoidance and pain intensity: The paradox of chronic pain.

Science.gov (United States)

Kroska, Emily B

2016-10-01

for studies that utilized measures of experiential avoidance when compared to studies that utilized pain-specific fear-avoidance measures. Studies that utilized multiple measures of fear-avoidance had stronger effect sizes than studies that utilized a single measure of fear-avoidance. Three of Hofstede's cultural dimensions moderated the association, including Power Distance Index, Individualism versus Collectivism, and Indulgence versus Restraint. The present meta-analysis synthesizes the results from studies examining the association between fear-avoidance and pain intensity among individuals with chronic pain. The positive association indicates that those with increased fear-avoidance have higher pain intensity, and those with higher pain intensity have increased fear-avoidance. Findings indicate that cultural differences and measurement instruments are important to consider in understanding the variables that affect this association. The significant cultural variations may indicate that it is important to consider the function of avoidance behavior in different cultures in an effort to better understand each patient's cultural beliefs, as well as how these beliefs are related to pain and associated coping strategies. The results from the current meta-analysis can be used to inform interventions for patients with chronic pain. In particular, those with more intense pain or increased fear-avoidance should be targeted for prevention and intervention work. Within the intervention itself, avoidance should be undermined and established as an ineffective strategy to manage pain in an effort to prevent disability, depression, and physical deconditioning.

Concerns about crystal methamphetamine use and harm have increased in multiple countries. This paper describes how changes in the availability and use of crystal methamphetamine have impacted on methamphetamine-related harms in Australia. Data on methamphetamine use were obtained from population-level surveys, health service data and surveys of drug use among sentinel groups of ecstasy users and people who inject drugs. Data were obtained on seizures, arrests, clandestine laboratory detections, hospital separations, mental health unit admissions, drug telephone helpline calls and drug treatment episodes. Segmented linear regression models were fitted to identify changes in these series using log-transformed data where appropriate. The availability of crystal methamphetamine has increased as evidenced by increased laboratory detections, domestic seizures and purity of the seized drug. Population surveys do not report an increase in the number of people who used at least once in the past year. However, more users report using crystal methamphetamine rather than lower-purity powder methamphetamine and more regular use. Indicators of methamphetamine-related harms have increased in parallel with this change. Amphetamine-related helpline calls, drug treatment, arrests and hospital admissions for amphetamine disorders and psychosis all peaked in the mid-2000s, declined for several years and have increased steeply since 2010. The increased availability and use of crystal methamphetamine have been associated with increased regular use and harms. Treatment is required for those experiencing problems and the capacity of health services to provide care needs to be enhanced.[Degenhardt L, Sara G, Connor JP, McKetin R, Roxburgh A, Dobbins T, Farrell M, Burns L, Hall WD.

Pan, Pei-Yin; Yeh, Chin-Bin

2018-06-01

To explore the role of Internet addiction in the development of self-harm/suicidal behavior among adolescents after 1-year of follow-up. We conducted this 1-year, prospective cohort study of 1861 adolescents (mean age 15.93 years) attending a senior high school in Taiwan; 1735 respondents (93.2%) were classified as having no history of self-harm/suicidal attempts in the initial assessment and were referred to as the "noncase" cohort. The Chen Internet Addiction Scale was used to identify individuals with Internet addiction. The participants were evaluated for self-harm/suicidal behavior again 1 year later and the "noncase" cohort was selected for statistical analysis. To examine the relationship between Internet addiction and self-harm/suicidal behavior, multivariate logistic regression analysis was performed using Internet addiction at baseline as the predictor for newly developed self-harm/suicidal behavior in the next year, after adjustment for potential confounding variables. The prevalence rate of Internet addiction at baseline was 23.0%. There were 59 students (3.9%) who were identified as having developed new self-harm/suicidal behaviors on follow-up assessments. After controlling for the effects of potential confounders, the relative risk of newly emerging self-harm/suicidal behavior for participants who were classified as Internet addicted was 2.41 (95% CI 1.16-4.99, P = .018) when compared with those without Internet addiction. Our findings indicate that Internet addiction is prospectively associated with the incidence of self-harm/suicidal behavior in adolescents. Copyright © 2018 Elsevier Inc. All rights reserved.

The impact of borderline personality disorder and sub-threshold borderline personality disorder on the course of self-reported and clinician-rated depression in self-harming adolescents.

Studies on adults suggest that the presence of comorbid depression and Borderline Personality Disorder (BPD) is associated with an elevated risk of self-harming behaviours and that self-harming behaviours, when present, will have higher severity. This comorbidity, furthermore, complicates clinical assessments, which may be an obstacle to early identification and proper intervention. Adolescents who self-harm frequently report high levels of depressive symptoms, but this is often not reflected in the clinicians' assessment. BPD is still a controversial diagnosis in young people, and less is known about the clinical significance of comorbid BPD in adolescent populations.The purpose of the present study was to examine the impact of BPD on the assessment and course of self-reported and clinician-rated depression in self-harming adolescents before and after a treatment period of 19 weeks. We hypothesized that, compared to adolescents without BPD, adolescents with BPD would self-report higher levels of depression at baseline, and that they would have less reduction in depressive symptoms. A total of 39 adolescents with depressive disorders and BPD-traits participating in a randomised controlled trial on treatment of self-harm with Dialectical Behaviour Therapy adapted for Adolescents or enhanced usual care were included. Adolescents with full-syndrome BPD ( n  = 10) were compared with adolescents with sub-threshold BPD ( n  = 29) with respect to their self-reported and clinician-rated depressive symptoms, suicidal ideation and global level of functioning at baseline, and after 19 weeks of treatment (end of trial period). At baseline, adolescents with full-syndrome BPD self-reported significantly higher levels of depressive symptoms and suicidal ideation compared to adolescents with sub-threshold BPD, whereas the two groups were rated as equally depressed by the clinicians. At trial completion, all participants had a significant reduction in suicidal ideation

Borderline personality disorder (BPD) is associated with frequent self-harm and suicidal behaviours. This study compared physician-assessed self-harm risk and intervention choice according to a (i) standard risk assessment and (ii) BPD-specific risk assessment methods. Forty-five junior and senior mental health physicians were assigned to standard or BPD-specific risk training groups. The assessment utilized a BPD case vignette containing four scenarios describing high/low lethality self-harm and chronic/new patterns of self-harm behaviour. Participants chose from among four interventions, each corresponding to a risk category. Standard and BPD-specific groups were alike in their assessment of self-harm risk. Divergence occurred on intervention choice for assessments of low lethality, chronic risk ( pself harm-associated risk, BPD-specific training raised awareness of BPD-appropriate interventions, particularly in the context of chronic patterns of self-harm behaviour. Wider dissemination of BPD-specific risk training may enhance the confidence of mental health clinicians in identifying the nature of self-harm risk as well as the most clinically appropriate interventions for clients with BPD.

Botanical insecticides are a promising alternative to reduce the harmful effects of synthetic chemicals. Among the botanical biopesticides, azadirachtin obtained from the Indian neem tree Azadirachta indica A. Juss. (Meliaceae) is probably the biorational insecticide with greatest agriculture use nowadays due to its broad insecticide activity. The current study, evaluated the lethal and sublethal effects of azadirachtin on larval avoidance, food intake and digestive enzymes of Drosophila melanogaster larvae as biological model. Azadirachtin was applied topically at two doses LD 25 (0.28μg) and LD 50 (0.67μg) on early third instars larvae. Results evaluated 24h after treatment showed that larvae exhibited significant repellence to azadirachtin and prefer keeping in untreated arenas rather than moving to treated one. In addition, azadirachtin avoidance was more marked in larvae previously treated with this compound as compared with naïf larvae (controls). Moreover, azadirachtin treatment decreased significantly the amount of larval food intake. Finally, azadirachtin reduced significantly the activity of larval α-amylase, chitinase and protease and increased the activity of lipase. This finding showed that azadirachtin induced behavioral and physiological disruption affecting the ability of the insect to digest food. This rapid installation of avoidance and long term antifeedancy might reinforce the action of azadirachtin and provide a new behavioral strategy for integrated pest management programs.

Habitat selection by fish is the outcome of a choice between different stimuli. Typically, the presence of food tends to attract organisms, while contamination triggers an avoidance response to prevent toxic effects. Given that both food and contaminants are not homogeneously distributed in the environment and that food can be available in contaminated zones, a key question has been put forward in the present study: does a higher availability of food in contaminated areas interfere in the avoidance response to contaminants regardless of the contamination level? Tilapia fry (Oreochromis sp.; 2.5-3.0 cm and 0.5-0.8 g) were exposed to two different effluent samples, diluted along a free-choice, non-forced exposure system simulating a contamination gradient. Initially, avoidance to the effluents was checked during a one hour exposure. Afterwards, food was added to the system so that the availability of food increased with the increase in the level of contamination, and the avoidance response to contamination was checked during another hour. Results clearly showed a concentration-dependent avoidance response for both effluents during the first hour (i.e., with no food). However, in presence of the food, the avoidance pattern was altered: organisms were propelled to intermittently move towards contaminated areas where food availability was higher. The incursions were taken regardless of the potential risk linked to the toxic effects. In conclusion, even when the risk of toxicity was imminent, tilapia fry were more intensively stimulated by the attractiveness of the food than by repulsion to the contamination.

Objective To determine whether adolescents who self-harm are at increased risk of heavy and dependent substance use in adulthood. Method Fifteen-year prospective cohort study of a random sample of 1943 adolescents recruited from secondary schools across the state of Victoria, Australia. Data pertaining to self-harm and substance use was obtained at seven waves of follow-up, from mean age 15.9 years to mean age 29.1 years. Results Substance use and self-harm were strongly associated during the adolescent years (odds ratio (OR): 3.3, 95% CI 2.1–5.0). Moreover, adolescent self-harmers were at increased risk of substance use and dependence syndromes in young adulthood. Self-harm predicted a four-fold increase in the odds of multiple dependence syndromes (sex- and wave-adjusted OR: 4.2, 95% CI: 2.7–6.6). Adjustment for adolescent anxiety/depression attenuated but did not eliminate most associations. Adolescent substance use confounded all associations, with the exception of multiple dependence syndromes, which remained robustly associated with adolescent self-harm (fully adjusted odds ratio: 2.0, 95% CI: 1.2–3.2). Conclusion Adolescent self-harm is an independent risk factor for multiple dependence syndromes in adulthood. This level of substance misuse is likely to contribute substantially to the premature mortality and disease burden experienced by individuals who self-harm. PMID:24954250

Perceptions of the Harm and Addictiveness of Conventional Cigarette Smoking Among Adolescent E-Cigarette Users.

Although existing evidence indicates that e-cigarette use is a risk factor for cigarette smoking initiation, mechanisms of this association are not yet known. E-cigarette users perceive e-cigarette use to be less harmful relative to conventional cigarettes, but their absolute perceptions of addictiveness of conventional cigarette smoking are unknown. This study examines how e-cigarette users compare with nonusers (non-e-cigarette users/nonconventional cigarette smokers), conventional cigarette smokers, and dual users on perceptions of harm and the addictiveness of conventional cigarette smoking and on other known predictors of cigarette smoking such as peer smoking, influence of antismoking ads, and risk-taking propensity. National samples of 8th- and 10th-grade students from 2014 and 2015 (N = 14,151) were obtained from the Monitoring the Future Study. Multivariate logistic regression models were used to examine relationships between adolescent smoking status and perceptions of harm and the addictiveness of conventional cigarette smoking while controlling for potential confounders. E-cigarette users had lower perceptions of the addictiveness of conventional cigarette smoking compared with nonusers but higher than cigarette smokers and dual users. E-cigarette users reported lower influence by antismoking ads, more conventional cigarette-smoking peers, and greater risk-taking propensity than nonusers. E-cigarette users and cigarette smokers did not differ in their perceived harm of conventional cigarette smoking or in their risk-taking propensity. E-cigarette users' attitudes and perceptions regarding conventional cigarette smoking may leave them vulnerable to becoming conventional cigarette smokers. Future studies should explore the prospective relationship between smoking-related perceptions of conventional cigarette smoking among e-cigarette users and the onset of cigarette smoking.

The report describes a complex biotest in which algae serve as the test organisms and where a variety of algal characteristics are employed as indicators of the effects of harmful radiations on the cultures and single organisms. Rules for a successful choice of a suitable algal organism are discussed and the preparation of the latter for the test as well as the growth and morphogenic tests and some physiological responses of algae to harmful radiation are described. The survival and lethality are related to the interpretation of the test results particularly from the physiological and genetic points of view. The complex biotest concerns not only toxic but also mutagenic effects of the factors tested. Some easily detectable mutations in algae are mentioned and their spectra are recommended. The stability of the mutations and the possibility of their delayed manifestation are considered. The possibility of occurrence of teratogenic effects is also dealt with and the negative role of phenocopies in the correct evaluation of the mutation effects is mentioned. Advice for the breeding and laboratory maintenance of suitable algal strains for the biotest is given. Practical use of the biotest is demonstrated on the results of a test using modified samples of waste water from uranium industries. It is recommended that biotests confined to the evaluation of single characteristics of the test organism be replaced by this complex biotest whose results can be interpreted more extensively and exhibit a higher reliability.

How we make decisions that have direct consequences for ourselves and others forms the moral foundation of our society. Whereas economic theory contends that humans aim at maximizing their own gains, recent seminal psychological work suggests that our behavior is instead hyperaltruistic: We are more willing to sacrifice gains to spare others from harm than to spare ourselves from harm. To investigate how such egoistic and hyperaltruistic tendencies influence moral decision making, we investigated trade-off decisions combining monetary rewards and painful electric shocks, administered to the participants themselves or an anonymous other. Whereas we replicated the notion of hyperaltruism (i.e., the willingness to forego reward to spare others from harm), we observed strongly egoistic tendencies in participants' unwillingness to harm themselves for others' benefit. The moral principle guiding intersubject trade-off decision making observed in our study is best described as egoistically biased altruism, with important implications for our understanding of economic and social interactions in our society.

The Impact of Experiential Avoidance on the Inference of Characters' Emotions: Evidence for an Emotional Processing Bias.

Experiential avoidance is a functional class of maladaptive strategies that contribute to the development and maintenance of psychopathology. Although previous research has demonstrated group differences in the interpretation of aversive stimuli, there is limited work on the influence of experiential avoidance during the online processing of emotion. An experimental design investigated the influence of self-reported experiential avoidance during emotion processing by assessing emotion inferences during the comprehension of narratives that imply different emotions. Results suggest that experiential avoidance is partially characterized by an emotional information processing bias. Specifically, individuals reporting higher experiential avoidance scores exhibited a bias towards activating negative emotion inferences, whereas individuals reporting lower experiential avoidance scores exhibited a bias towards activating positive emotion inferences. Minimal emotional inference was observed for the non-bias affective valence. Findings are discussed in terms of the implications of experiential avoidance as a cognitive vulnerability for psychopathology.

Body image avoidance is conceptualised as a behavioural manifestation of body image disturbance, and describes efforts to avoid confrontation with one's own body. While studies have provided hints that body image avoidance in adulthood contributes to the development and maintenance of eating disorders, so far, there are no corresponding findings for adolescence. The Body Image Avoidance Questionnaire (BIAQ) is the most widely used international questionnaire for measuring body-related avoidance behaviour. As its German version has only been validated in an adult sample, the aim of the present study is to statistically test the questionnaire in adolescents with eating disorders. In total, N=127 female adolescents, including n=57 with Anorexia Nervosa, n=24 with Bulimia Nervosa, and n=46 healthy controls, answered the BIAQ as well as various other instruments for assessing body image disturbance and eating disorder symptoms. The factor structure assumed for the original English version, comprising the higher-order factor "body-related avoidance behaviour" and the 4 subfactors "clothing", "social activities", "eating restraint" and "grooming and weighing", was confirmed by a confirmatory factor analysis. With the exception of the scale "grooming and weighing", all scales showed mostly acceptable internal consistencies, test-retest reliability, differential validity and construct validity. Due to their satisfying psychometric properties, the use of the BIAQ scales "clothing", "social activities" and "eating restraint" can be recommended in research and practice for adolescence. © Georg Thieme Verlag KG Stuttgart · New York.
