The objective of the present study was to interview infantry soldiers to determine their preferences with respect to rifle design and to examine the effect of buttstocks on shooting performance. Factor analysis showed that seven main factors should be considered in rifle redesign including tactics necessary, interface design, saving weight, bullpup configuration, sight design, other devices, and bayonet lug. For the shooting experiment, a total of four shooting trials were performed with the T-91 rifle, with buttstock lengths of 26 mm, 34 mm, self-adjusting stock, and bullpup stock. The analysis revealed that buttstock length had a significant effect on shooting performance. The redesigned rifle weight and total length should be reduced to 3.2 kg and 750 mm, respectively. The rifle buttstock should be a non-adjustable bullpup style. The buttstock shape should be curved and the hand-guard type should be more deeply and density seams, while the trigger handle shape should be slanted.

Self-inflicted injury in adolescence indicates significant emotional and psychological suffering. Although data on the etiology of self-injury are limited, current theories suggest that the emotional lability observed among self-injuring adolescents results from complex interactions between individual biological vulnerabilities and environmental risk. For example, deficiencies in serotonergic functioning, in conjunction with certain family interaction patterns, may contribute to the development of emotional lability and risk for self-injury. The authors explored the relation between peripheral serotonin levels and mother–child interaction patterns among typical (n = 21) and self-injuring (n = 20) adolescents. Findings revealed higher levels of negative affect and lower levels of both positive affect and cohesiveness among families of self-injuring participants. Peripheral serotonin was also correlated with the expression of positive affect within dyads. Furthermore, adolescents’ serotonin levels interacted with negativity and conflict within dyads to explain 64% of the variance in self-injury. These findings underscore the importance of considering both biological and environmental risk factors in understanding and treating self-injuring adolescents. PMID:18229978

Background Although self-inflicted and assault-induced knife injuries might have different mortality and morbidity rates, no studies have actually evaluated the importance of the cause of knife injuries in terms of patient outcomes and treatment strategies. Objectives The aims of this study were to assess the difference between the outcomes of patients presenting with self-inflicted stab wounds (SISW) versus assault-induced stab wounds (AISW). Patients and Methods A retrospective review of the relevant electronic medical records was performed for the period between January 2000 and December 2012 for patients who were referred to the department of surgery for stab wounds by the trauma team. The patients were divided into either SISW (n = 10) or AISW groups (n = 11), depending on the cause of the injury. Results A total of 19 patients had undergone exploratory laparotomy. Of the nine patients with SISW undergoing this procedure, no injury was found in seven of the patients. In the AISW group, eight of the ten laparotomies were therapeutic. Three patients in the AISW group died during hospital admission. The average number of stab wounds was 1.2 for the SISW group and 3.5 for the AISW group. Organ injuries were more frequent in the AISW group, affecting the lung (2), diaphragm (3), liver (5), small bowel (2), colon (2), and kidney (1). Conclusions Although evaluations of the initial vital signs and physical examinations are still important, the history regarding the source of the stab wounds (AISW vs. SISW) may be helpful in determining the appropriate treatment methods and predicting patient outcomes.

Smuin, D.R.; Wilson, M.J.; Crutcher, J.W.

In addition to examining anomalies and establishing the background gamma exposure rate range, the study presents a formula to convert thousand counts per minute (kcpm) from a gamma scintillator to microroentgen per hour (μRh) for the Rifle region. Also, a method is presented to identify contaminated areas containing excess 226 Ra, by using a GR-410 gamma spectrometer. This method is suggested to be applied to all property surveys in the Rifle area. The Wasatch Formation, which outcrops extensively in the Rifle area, was found to have a major influence on the background radiation. Varying potassium concentrations and naturally occurring uranium in this rock unit reveal varying gamma exposure rates. Examining RaTh ratios from laboratory analysis of soil samples or use of RaTh ratios from GR-410 gamma spectrometer readings on site allows discrimination between mill related contamination and naturally occuring radioactivity. Radioactive coal clinkers were found used as fill material throughout the Rifle region and have been determined to be a product of the mill and subject to remediation. Finally, windblown mill tailings contamination is addressed in some detail. Mill tailings redistributed from the Rifle uranium mill tailings piles by prevailing winds were detected extensively on vicinity properties in Rifle. Some radioactive components of the windblown tailings were found to have leached into the subsurface soil. The combination of Wasatch Formation, radioactive coal clinkers, and windblown tailings accounts for many of the anomalous gamma exposure rates observed by the radiological survey teams. 11 refs., 10 figs., 3 tabs

Private well/spring position paper, Rifle, Colorado, sites

International Nuclear Information System (INIS)

1995-05-01

This report describes the hydrogeochemical relationship between the New and Old Rifle processing sites and 15 domestic wells in their vicinity. The relationship of the domestic wells to the Old and New Rifle tailings sites requires clarification due to recent advances in understanding of Rifle site conceptual models. In order to form a bridge from the Rifle remedial action plan (RAP) and the recent baseline risk assessment to this position paper, several issues require discussion. First, through analysis of long-term ground water level data, the hydraulic gradient between the former tailings and private wells and springs was assessed. Second, in the Rifle RAP there was not a strong emphasis placed on describing regional influences on water quality in the vicinity of the processing sites. This document uses available information coupled with theory of regional ground water flow to describe regional flow systems north of Rifle. Third, the definition of background water quality from the RAP has been refined in several ways. Also, for the recent baseline risk assessment, all alluvial wells used to define background for the sites were located east of Old Rifle. In the RAP, alluvial background wells were also placed between the sites (downgradient of Old Rifle). Two additional wells were installed for the recent baseline risk assessment upgradient of Old Rifle which verified that several of the older wells (RFO-01-0597 and -0598) were in locations representative of background

Patients with self-inflicted burns (SIB) are thought to have a longer length of stay compared to patients with accidental burns. However, other predictors for a longer length of stay are often not taken into account, e.g. percentage of the body surface area burned, age or comorbidities. Therefore, we wanted to study the outcome of patients with SIB at our burn center. A retrospective, observational study was conducted. All adult patients with acute burns admitted to the burn center of the Martini Hospital Groningen, between January 1, 2009 and December 31, 2013 were included. Data on characteristics of the patient, injury, and outcome (LOS, mortality, discharge destination) were collected. In patients with SIB, suicide attempts (SA) were distinguished from self-harm without the intention to die (non-suicidal self-injury, NSSI). To evaluate differences in outcome, each patient with SIB was matched on variables and total score of the Abbreviated Burn Severity Index (ABSI) to a patient with accidental burns (AB). In total 29 admissions (21 SA and 8 NSSI) were due to SIB and 528 due to accidents. Overall, when compared to AB, there were significant differences with respect to mortality and LOS for SA and/or NSSI. Mortality was higher in the SA group, while the LOS was higher in both the SA and NSSI groups compared to the AB group. However, after matching on ABSI, no statistical significant differences between the SA and SA-match or the NSSI and NSSI-match group were found. With the right and timely treatment, differences in mortality rate or length of stay in hospital could all be explained by the severity of the burn and the intention of the patient.

Work plan for preliminary investigation of organic constituents in ground water at the New Rifle site, Rifle, Colorado. Revision 2

International Nuclear Information System (INIS)

1996-01-01

A special study screening for Appendix 9 (40 CFR Part 264) analytes identified the New Rifle site as a target for additional screening for organic constituents. Because of this recommendation and the findings in a recent independent technical review, the US Department of Energy (DOE) has requested that the Technical Assistance Contractor (TAC) perform a preliminary investigation of the potential presence of organic compounds in the ground water at the New Rifle Uranium Mill Tailings Remedial Action (UMTRA) Project site, Rifle, Colorado. From 1958 to 1972, organic chemicals were used in large quantities during ore processing at the New Rifle site, and it is possible that some fraction was released to the environment. Therefore, the primary objective of this investigation is to determine whether organic chemicals used at the milling facility are present in the ground water. The purpose of this document is to describe the work that will be performed and the procedures that will be followed during installation of ground water well points at the New Rifle site. The selection of analytes and the procedures for collecting ground water samples for analysis of organic constituents are also described

2018-05-01

The experimental investigation of heat transfer of water flowing in a rifled tube was explored at different pressures and at various operating conditions in a rifled tube heat exchanger. The specifications for the inner and outer diameters of the inner tube are 25.8 and 50.6 mm, respectively. The working fluids used in shell side and tube side are cold and hot water. The rifled tube was made of the stainless steel with 4 ribs, 50.6 mm outer diameter, 0.775 mm rib height, 58o helix angle and the length 1500 mm. The effect of pressure, wall heat flux and friction factor were discussed. The results confirm that even at low pressures the rifled tubes has an obvious enhancement in heat transfer compared with smooth tube. Results depicts that the Nusselt number increases with Reynolds number and the friction factor decreases with increase in Reynolds number and the heat transfer rate is higher for the rifled tube when compared to smooth tube, because of strong swirl flow due to centrifugal action. It also confirms that, the friction factor obtained from the rifled tube is significantly higher than that of smooth tube.

Suicides and attempted suicides are major public health issues in the United States and around the world. Self-inflicted gunshot wounds (SIGSWs) are a common method of attempting suicide, the head being the most commonly injured body region; however, the literature lacks an overview of the orbital and ocular injuries as well as outcomes associated with SIGSWs. To characterize the ocular and orbital injuries and outcomes of patients presenting with SIGSWs and to examine the cost associated with these injuries. Retrospective medical record review was performed of all patients who presented to the University of Iowa Hospitals and Clinics between 2003 to 2013 with the admitting diagnosis of self-inflicted injuries via firearms. Patients with no periorbital or ocular injuries and/or those who did not survive for at least 2 months following the incident were excluded. Ocular injuries and outcomes and health care costs and reimbursements, which were generated by a financial report obtained from the hospital finance department that included data from both the hospital billing and cost accounting systems. All patients in this study (n = 18) were men with a mean age of 47.2 years. Eight patients (44.4%) displayed submental missile entry points, 7 (38.9%) displayed intraoral entry points, and 3 (16.7%) displayed pericranial entry points. Patients with pericranial entries sustained more severe ocular injuries and had poorer ocular outcomes. Seven patients (38.9%) were found at final follow-up to have visual acuity of 20/40 or better in each eye and all showed missile trajectories in the sagittal plane. The mean cost of treatment of these patients totaled $117,338 while the mean reimbursement amount was $124,388. Data regarding ocular injuries and outcomes may assist ophthalmologists in the treatment of patients with SIGSWs in the future. Many patients had extremely functional vision at final follow-ups, which highlights the importance of specialists conducting examinations

Development of self-inflicted injury: Comorbidities and continuities with borderline and antisocial personality traits.

Science.gov (United States)

Crowell, Sheila E; Kaufman, Erin A

2016-11-01

Self-inflicted injury (SII) is a continuum of intentionally self-destructive behaviors, including nonsuicidal self-injuries, suicide attempts, and death by suicide. These behaviors are among the most pressing yet perplexing clinical problems, affecting males and females of every race, ethnicity, culture, socioeconomic status, and nearly every age. The complexity of these behaviors has spurred an immense literature documenting risk and vulnerability factors ranging from individual to societal levels of analysis. However, there have been relatively few attempts to articulate a life span developmental model that integrates ontogenenic processes across these diverse systems. The objective of this review is to outline such a model with a focus on how observed patterns of comorbidity and continuity can inform developmental theories, early prevention efforts, and intervention across traditional diagnostic boundaries. Specifically, when SII is viewed through the developmental psychopathology lens, it becomes apparent that early temperamental risk factors are associated with risk for SII and a range of highly comorbid conditions, such as borderline and antisocial personality disorders. Prevention efforts focused on early-emerging biological and temperamental contributors to psychopathology have great potential to reduce risk for many presumably distinct clinical problems. Such work requires identification of early biological vulnerabilities, behaviorally conditioned social mechanisms, as well as societal inequities that contribute to self-injury and underlie intergenerational transmission of risk.

To characterize and compare subgroups of survivors with assault-related versus self-inflicted traumatic brain injuries (TBIs) via firearms at the time of inpatient rehabilitation and at 1-, 2-, and 5-year follow-up. Secondary analysis of data from the Traumatic Brain Injury Model Systems National Database (TBIMS NDB), a multicenter, longitudinal cohort study. Retrospective analyses of a subset of individuals enrolled in the TBIMS NDB. Individuals 16 years and older (N=399; 310 via assault, 89 via self-inflicted injury) with a primary diagnosis of TBI caused by firearm injury enrolled in the TBIMS NDB. Not applicable. Disability Rating Scale, Glasgow Outcome Scale-Extended, sociodemographic variables (sex, age, race, marital status), injury-related/acute care information (posttraumatic amnesia, loss of consciousness, time from injury to acute hospital discharge), and mental health variables (substance use history, psychiatric hospitalizations, suicide history, incarcerations). Individuals who survived TBI secondary to a firearm injury differed by injury mechanism (assault vs self-inflicted) on critical demographic, injury-related/acute care, and mental health variables at inpatient rehabilitation and across long-term recovery. Groups differed in terms of geographic area, age, ethnicity, education, marital status, admission Glasgow Coma Scale score, and alcohol abuse, suicide attempts, and psychiatric hospitalizations at various time points. These findings have implications for prevention (eg, mental health programming and access to firearms in targeted areas) and for rehabilitation planning (eg, by incorporating training with coping strategies and implementation of addictions-related services) for firearm-related TBI, based on subtype of injury.

Water samples were collected from 36 locations at New Rifle and Old Rifle, Colorado, Processing Sites. Duplicate samples were collected from New Rifle locations 0659 and 0855, and Old Rifle location 0304. One equipment blank was collected after decontamination of non-dedicated equipment used to collect one surface water sample. Sampling and analyses were conducted as specified in the Sampling and Analysis Plan for U.S. Department of Energy Office of Legacy Management Sites (LMS/PRO/S04351, continually updated). New Rifle Site Samples were collected at the New Rifle site from 16 monitoring wells and 7 surface locations in compliance with the December 2008 Groundwater Compliance Action Plan [GCAP] for the New Rifle, Colorado, Processing Site (LMS/RFN/S01920), with one exception: New Rifle location 0635 could not be sampled because it was inaccessible; a fence installed by the Colorado Department of Transportation prevents access to this location. DOE is currently negotiating access with the Colorado Department of Transportation. Analytes measured at the New Rifle site included contaminants of concern (COCs) (arsenic, molybdenum, nitrate + nitrite as nitrogen, selenium, uranium, and vanadium) ammonia as nitrogen, major cations, and major anions. Field measurements of total alkalinity, oxidation- reduction potential, pH, specific conductance, turbidity, and temperature were made at each location, and the water level was measured at each sampled well. A proposed alternate concentration limit (ACL) for vanadium of 50 milligrams per liter (mg/L), specific to the compliance (POC) wells (RFN-0217, -0659, -0664, and -0669) is included in the New Rifle GCAP. Vanadium concentrations in the POC wells were below the proposed ACL as shown in the time-concentration graphs in the Data Presentation section (Attachment 2). Time-concentration graphs from all other locations sampled are also included in Attachment 2. Sampling location RFN-0195 was misidentified for the June/August 2014

UMTRA project water sampling and analysis plan, Old and New Rifle, Colorado

International Nuclear Information System (INIS)

1994-07-01

Surface remedial action at the Rifle, Colorado, Uranium Mill Tailings Remedial Action (UMTRA) Project site began in the spring of 1992. Results of water sampling at the Old and New Rifle processing sites for recent years indicate that ground water contamination occurs in the shallow unconfined alluvial aquifer (the uppermost aquifer) and less extensively in the underlying Wasatch Formation. Uranium and sulfate continue to exceed background ground water concentrations and/or maximum concentration limits at and downgradient from the former processing sites. These constituents provide the best indication of changes in contaminant distribution. Contamination in the uppermost (alluvial) aquifer at New Rifle extends a minimum of approximately 5000 feet (ft) (1,524 meters [m]) downgradient. At Old Rifle, the extent of contamination in the alluvial aquifer is much less (a minimum of approximately 1,000 ft [305 m]), partially due to differences in hydrologic regime. For example, the Old Rifle site lies in a relatively narrow alluvial floodplain; the New Rifle site lies in a broad floodplain. Data gathering for the Rifle baseline risk assessment is under way. The purpose of this effort is to determine with greater precision the background ground water quality and extent of ground water contamination at the processing sites. Historical surface water quality indicates that the Colorado River has not been affected by uranium processing activities. No compliance monitoring of the Estes Gulch disposal cell has been proposed, because ground water in the underlying Wasatch Formation is limited use (Class 111) ground water and because the disposal cell is hydrogeologically isolated from the uppermost aquifer

Are There Ways out of the Self-inflicted Irrelevance of the Qualitative Off-stream?

Directory of Open Access Journals (Sweden)

Norbert Groeben

2006-09-01

Full Text Available The qualitative paradigm is relatively irrelevant in psychological research and teaching, which is not only due to the hegemony of the quantitative paradigm. This irrelevance also arises from the fragmentation within the qualitative research paradigm, which is a result of the principle of a close interdependence of research object and method; this fragmentation is evident in the lack of a systematic approach to the concept of method. The conviction to conduct a superior psychological approach leads to destructive competition both within the qualitative paradigm and in relation to the quantitative paradigm. Instead, I recommend the pursuit of approaches that attempt to integrate qualitative and quantitative research methods on the basis of the idea of ontological layers, clearly distinct from esoteric approaches. Above all, the development of sophisticated and complex methods of statistical analysis appears a promising way to overcome the self-inflicted irrelevance of the qualitative research paradigm.

Saadat, Mostafa; Zendeh-Boodi, Zahra

2006-09-01

The aim of the study is to obtain more insight into the possible association between consanguinity and the incidence of deliberate self-burning. Data were obtained by analysis of medical records of patients hospitalized in two referral burn centers: Chormy Burn Center (Bushehr Province, south of Iran) from March 21, 1998, through March 20, 2004, and Shahid Sadoqi Center of Burns and Injuries (Yazd Province, center of Iran) from March 21, 2000, through March 20, 2004. The incidence of suicidal burns was 6.51 and 2.32/100,000 person-years for Bushehr and Yazd Provinces, respectively. The observed sex ratio of patients in both centers indicated there was a female predominance in patients with self-inflicted burns. Using patients' home addresses, patients were sorted into 16 cities. The incidence of suicide by self-burning ranged from 0.80 (for Tabas, located in Yazd Province) to 12.60/100,000 person-years (for Dilam, located in Bushehr Province). The coefficient of inbreeding defines the probability that an individual received both alleles of a pair from an identical ancestral source. There was a significant correlation between incidences of suicidal burns and mean coefficient of inbreeding (r = 0.782, df = 14, p < 0.001). In addition to other factors, consanguineous marriage may be a risk factor that influences the incidence of suicidal burns in a population.

2000-04-01

This study reports the findings of part of an ongoing research program examining sports performers' interpretations of competitive anxiety prior to competition. The notion of 'directional perceptions' has questioned the limited utility of examining only the intensity of competitive anxiety responses as has Jones. The purpose of this study was to examine intensity and direction, i.e., interpretation of intensity as facilitative or debilitative, of anxiety symptoms as a function of two types of sport. The types of sport were explosive (rugby league) versus fine motor skills (target rifle shooting). The sample comprised 50 male rugby league participants and 50 target rifle shooters who completed a modified version of the Competitive State Anxiety Inventory-2 prior to competition. Contingency analysis yielded a significant difference in the number of rugby players who reported somatic anxiety as facilitative and the number of rifle shooters who reported somatic states as debilitative. No such differences were evident for cognitive anxiety. Analysis of variance indicated no differences between the two groups on the intensity of cognitive and somatic anxiety, but the performers competing in rugby league interpreted both states as being more facilitative to performance; the rugby league players also had higher scores on self-confidence than the shooters. These findings provide continuing support for the measurement of directional perceptions of competitive anxiety and highlight the importance of examining individual sports.

Engineering assessment of inactive uranium mill tailings, Rifle Site, Rifle, Colorado. Summary of the Phase II, Title I

International Nuclear Information System (INIS)

1977-10-01

Ford, Bacon and Davis Utah Inc. has performed an engineering assessment of the problems resulting from the existence of radioactive uranium mill tailings at Rifle, Colorado. The Phase II - Title I services include the preparation of topographic maps, the performance of core drillings and radiometric measurements sufficient to determine areas and volumes of tailings and other radium-contaminated materials, the evaluation of resulting radiation exposures of individuals and nearby populations, the investigation of site hydrology and meteorology and the evaluation and costing of alternative corrective actions. Radon gas release from the 3.1 million tons of tailings at the two Rifle sites, constitutes the most significant environmental impact. Windblown tailings, external gamma radiation and localized contamination of surface waters are other environmental effects. The 15 alternative remedial action options presented range from millsite decomtamination and off-site remedial action (Options I and IV), to adding various depths of stabilization cover material (Options II, V, VI, and VII), to removal of the tailings to long-term storage sites and decontamination of the present sites (Options III and VIII through XV). Cost estimates for the first 14 options range from $224,000 to $20,300,000. Option XV, estimated at $32,200,000, includes the cost for moving both Rifle tailings piles and the Grand Junction tailings pile to DeBeque for long-term storage and site decontamination after removal of the piles. Reprocessing of the tailings for uranium appears to be economically attractive at present

Ford, Bacon and Davis Utah Inc. has performed an engineering assessment of the problems resulting from the existence of radioactive uranium mill tailings at Rifle, Colorado. The Phase II--Title I services include the preparation of topographic maps, the performance of core drillings and radiometric measurements sufficient to determine areas and volumes of tailings and other radium-contaminated materials, the evaluation of resulting radiation exposures of individuals and nearby populations, the investigation of site hydrology and meteorology and the evaluation and costing of alternative corrective actions. Radon gas release from the 3.1 million tons of tailings at the two Rifle sites, constitutes the most significant environmental impact. Windblown tailings, external gamma radiation and localized contamination of surface waters are other environmental effects. The 15 alternative remedial action options presented range from millsite decontamination and off-site remedial action (Options I and IV), to adding various depths of stabilization cover material (Options II, V, VI and VII), to removal of the tailings to long-term storage sites and decontamination of the present sites (Options III and VIII through XV). Cost estimates for the first 14 options range from $224,000 to $20,300,000.

Results of radiological surveys of two inactive uranium-mill sites near Rifle, Colorado, in May 1976 are presented. These sites are referred to as Old Rifle and New Rifle. The calculated 226 Ra inventory of the latter site is much higher than at the older mill location. Data on above-ground measurements of gamma exposure rates, surface and near-surface concentration of 226 Ra in soil and sediment samples, concentration of 226 Ra in water, calculated subsurface distribution of 226 Ra, and particulate radionuclide concentrations in air samples are given. The data serve to define the extent of contamination in the vicinity of the mill sites and their immediate surrounding areas with tailings particles. Results of these measurements were utilized as technical input for an engineering assessment of these two sites

To determine the incidence of acute renal failure (ARF) in critically ill patients using the RIFLE and AKIN criteria. A prospective, multicenter observational study with a duration of one year from February 2010 was carried out. RIFLE and AKIN were employed using the urinary (UC) and creatinine criteria (CC) jointly and separately. Nine polyvalent Critical Care Units (CCUs) in Argentina. A total of 627 critical patients over 18 years of age were admitted to the CCU for more than 48h. inability to quantify diuresis, surgical instrumentation of the urinary tract, and need for renal support therapy (RST). Calculated hourly diuresis (CHD) was used to apply the UC. The incidence of ARF was 69.4% and 51.8% according to RIFLE and AKIN, respectively. UC detected ARF in 59.5% of cases, while CC identified ARF in 34.7% (RIFLE) and 25.3% (AKIN). The mortality rate was 40.9% and 44.6% according to RIFLE and AKIN respectively, was significantly higher than in patients without ARF, and increased with disease severity (Data processing: Excel, SQL and SPSS. Levene test, comparison of means with Student t and chi-squared, with 95% confidence interval). RIFLE identified more cases of ARF. UC proved more effective than CC. The presence of ARF and severity levels were correlated to mortality but not to days of stay in the CCU. Implementation of the unified CHD was useful for implementing UC and achieving comparable results. Copyright © 2012 Elsevier España, S.L. and SEMICYUC. All rights reserved.

Made up by makeup--A case report about an exceptional kind of self-inflicted "injuries".

2015-12-01

Self-inflicted injuries are a known, but challenging topic in the healthcare sector and the judicial system. Therefore, differentiation of these injuries from a third-party-interference is crucial in the field of forensic medicine. However, self-painted injuries with makeup, which entail misleading of medical staff and the administration of justice, have apparently not been described in the literature so far. A case of a rare kind of victim role staging in a 26-year-old Caucasian woman in the field of forensic medicine is presented. She supposedly had been robbed and harmed by two unknown men. The forensic examination revealed subjective symptoms and objective findings, such as skin discolorations appearing as fresh bruises. However, a closer look revealed makeup. After removal, no injuries were seen. Awareness of the existence of exceptional cases of victim role staging is essential in the daily routine of healthcare, judicial and forensic professionals. Therefore, a questioning attitude within the physical examination as well as proper assessment of objective findings is crucial. Furthermore, the importance of an interdisciplinary approach of possible factitious disorders is demonstrated. The sensitization may exclude a third-party-interference, prevent damages to the health care system, avoid misleading of the administration of justice, and, therefore, reduce socioeconomic costs. Moreover, the recognition may enable adequate interventions and provide patients with professional help. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

Graphical abstract: Predicted laminar Nusselt number using regression correlation of Therminol-55 heat transfer fluid is in agreement with experiments in the rifled tube. - Highlights: • Heat transfer coefficient and friction factor are measured and predicted in the rifled tube. • Correlations for Nusselt number and friction factor are proposed. • The roughness height of 0.425 mm in transition SST model is suggested as an input parameter. • k–kl–ω transition and transition SST models are recommended for laminar–turbulent transition. • Thermal enhancement factor and synergy angle are predicted in the rifled tube. - Abstract: Simulations and experiments of flow and heat transfer behavior of Therminol-55 heat transfer fluid have been conducted in a horizontal rifled tube with outer diameter and inner diameter 25.0 and 20.0 mm, pitch and rib height of 12.0 and 1.0 mm, respectively. Numerical simulations of three-dimensional flow behavior of Therminol-55 heat transfer fluid are carried out using FLUENT code in the rifled tube. Experimental results show that the heat transfer and thermal performance of Therminol-55 heat transfer fluid in the rifled tube are considerably improved compared to those of the smooth tube. The Nusselt number increases with the increase of Reynolds number, and is from 3.5 to 5.1 times over the smooth tube. Also, the pressure drop results reveal that the average friction factor of the ribbed tube is in a range of 2.2 and 4.2 times over the smooth tube. Predictive Nusselt number and friction factor correlations have been presented. The numerical results show that the laminar flow model is valid only at lower Reynolds number in the developed laminar flow of rifled tube. The k–kl–ω transition model and transition SST model with roughness of 0.425 mm are recommended for the predictions of transition process from laminar to turbulent flow in the rifled tube.

Transmissible spongiform encephalopathies (TSE), also known as prion diseases, are characterized by rapid and fatal neurological decline. They not only detrimentally affect the patient, but also present additional challenges to healthcare systems due to the infectivity of the tissues and the difficulty of inactivating the prion. The most common TSE is Creutzfeldt-Jakob disease (CJD), which can occur after familial, spontaneous or acquired transmission. TSEs received more attention after the development of variant CJD (vCJD), also known as Mad Cow Disease, in the UK during the mid-1990s. Unlike familial or spontaneous CJD, this variant was connected to consumption of cattle contaminated with the prion disease, bovine spongiform encephalopathy.This development increased interest in the etiology of CJD and other TSEs and the risk it presents as an infectious disease. The following details the case of a 59-year-old male infected with CJD presented to our level II trauma center for treatment following a self-inflicted gunshot wound to the head.

Sampling Period: June 14–17 and July 7, 2016. Water samples were collected from 36 locations at New Rifle and Old Rifle, Colorado, Disposal/Processing Sites. Planned monitoring locations are shown in Attachment 1, Sampling and Analysis Work Order. Duplicate samples were collected from New Rifle locations 0216 and 0855, and Old Rifle location 0655. One equipment blank was collected after decontamination of non-dedicated equipment used to collect one surface water sample. See Attachment 2, Trip Report for additional details. Sampling and analyses were conducted as specified in the Sampling and Analysis Plan for U.S. Department of Energy Office of Legacy Management Sites (LMS/PRO/S04351, continually updated, http://energy.gov/lm/downloads/sampling-and- analysis-plan-us-department-energy-office-legacy-management-sites). New Rifle Site Samples were collected at the New Rifle site from 16 monitoring wells and 7 surface locations in compliance with the December 2008 Groundwater Compliance Action Plan [GCAP] for the New Rifle, Colorado, Processing Site (LMS/RFN/S01920). Monitoring well 0216 could not be sampled in June because it was surrounded by standing water due to the high river stage from spring runoff, it was later sampled in July. Monitoring well 0635 and surface location 0322 could not be sampled because access through the elk fence along Interstate 70 has not been completed at this time. Old Rifle Site Samples were collected at the Old Rifle site from eight monitoring wells and five surface locations in compliance with the December 2001 Ground Water Compliance Action Plan for the Old Rifle, Colorado, UMTRA Project Site (GJ0-2000-177-TAR).

The standard U.S. military rifle (M-16) is substantially more destructive than its Russian counterpart (AK-47) when fired at short range into clay blocks, despite the fact that the AK-47 is of larger caliber and fires a much heavier bullet with a kinetic energy (muzzle) 25% greater when compared to the M-16. The decisive factor is the 40% greater muzzle velocity of the M-16.

An assessment of potential hydrologic and ecologic impacts of constructing mitigation wetlands, Rifle, Colorado, UMTRA project sites

International Nuclear Information System (INIS)

1995-04-01

This-assessment examines the consequences and risks that could result from the proposed construction of mitigation wetlands at the New and Old Rifle Uranium Mill Tailings Remedial Action (UMTRA) Project sites near Rifle, Colorado. Remediation of surface contamination at those sites is now under way. Preexisting wetlands at or near the Old and New Rifle sites have been cleaned up, resulting in the loss of 0.7 and 10.5 wetland acres (ac) (0.28 and 4.2 hectares [ha]) respectively. Another 9.9 ac (4.0 ha) of wetlands are in the area of windblown contamination west of the New Rifle site. The US Army Corps of Engineers (USACE) has jurisdiction over the remediated wetlands. Before remedial action began, and before any wetlands were eliminated, the USACE issued a Section 404 Permit that included a mitigation plan for the wetlands to be lost. The mitigation plan calls for 34.2 ac (1 3.8 ha) of wetlands to be constructed at the south end and to the west of the New Rifle site. The mitigation wetlands would be constructed over and in the contaminated alluvial aquifer at the New Rifle site. As a result of the hydrologic characteristics of this aquifer, contaminated ground water would be expected to enter the environment through the proposed wetlands. A preliminary assessment was therefore required to assess any potential ecological risks associated with constructing the mitigation wetlands at the proposed location

Spatial distribution of an uranium-respiring betaproteobacterium at the Rifle, CO field research site.

Directory of Open Access Journals (Sweden)

Nicole M Koribanics

Full Text Available The Department of Energy's Integrated Field-Scale Subsurface Research Challenge Site (IFRC at Rifle, Colorado was created to address the gaps in knowledge on the mechanisms and rates of U(VI bioreduction in alluvial sediments. Previous studies at the Rifle IFRC have linked microbial processes to uranium immobilization during acetate amendment. Several key bacteria believed to be involved in radionuclide containment have been described; however, most of the evidence implicating uranium reduction with specific microbiota has been indirect. Here, we report on the cultivation of a microorganism from the Rifle IFRC that reduces uranium and appears to utilize it as a terminal electron acceptor for respiration with acetate as electron donor. Furthermore, this bacterium constitutes a significant proportion of the subsurface sediment community prior to biostimulation based on TRFLP profiling of 16S rRNA genes. 16S rRNA gene sequence analysis indicates that the microorganism is a betaproteobacterium with a high similarity to Burkholderia fungorum. This is, to our knowledge, the first report of a betaproteobacterium capable of uranium respiration. Our results indicate that this microorganism occurs commonly in alluvial sediments located between 3-6 m below ground surface at Rifle and may play a role in the initial reduction of uranium at the site.

[Child-pedestrian injuries inflicted in the road traffic accidents as a forensic medical problem].

Science.gov (United States)

Savenkova, E N; Efimov, A A

The road traffic accidents are known to make the greatest contribution to the overall structure of pediatric traumatism with the fatal outcome. The problem of pediatric traumatism remains on top of its relevancy despite numerous administrative, legal, technical, and financial measures taken at the government level in an attempt to reduce the mortality rate associated with the child-pedestrian injuries inflicted in the road traffic accidents. The objective of the present study was to summarize and interpret the results published in the scientific literature concerning child-pedestrian injuries inflicted in the road traffic accidents with special reference to the age of the victims and the type of the injury. The analysis of the publications of the domestic and foreign authors has demonstrated that the available data of interest remain to be systematized and that the forensic medical aspects of the problem in question are poorly represented in these materials. It was shown that forensic medical expertises of child-pedestrian injuries inflicted in the road traffic accidents are frequently carried out without taking into consideration the peculiar anatomical and physiological features of the child's organism. The available data concerning the mechanisms and evaluation of severe injuries inflicted to the children in the road traffic accidents are insufficient for the development of the algorithms for the relevant adequate forensic medical expertise. In the light of these findings, the problem of the child-pedestrian injuries inflicted in the road traffic accidents takes on new significance when considered in the context of pediatric traumatism. There is evidently the growing necessity to formulate the universal database containing systematized objective information for the development of new methods of forensic medical expertise for the elucidation of the mechanisms of road traffic injuries inflicted to the children of different age groups depending on the type of the

To evaluate whether a real-time electronic alert system or "AKI sniffer," which is based on the RIFLE classification criteria (Risk, Injury and Failure), would have an impact on therapeutic interventions and acute kidney injury progression. Prospective intervention study. Surgical and medical intensive care unit in a tertiary care hospital. A total of 951 patients having in total 1,079 admission episodes were admitted during the study period (prealert control group: 227, alert group: 616, and postalert control group: 236). Three study phases were compared: A 1.5-month prealert control phase in which physicians were blinded for the acute kidney injury sniffer and a 3-month intervention phase with real-time alerting of worsening RIFLE class through the Digital Enhanced Cordless Technology telephone system followed by a second 1.5-month postalert control phase. A total of 2593 acute kidney injury alerts were recorded with a balanced distribution over all study phases. Most acute kidney injury alerts were RIFLE class risk (59.8%) followed by RIFLE class injury (34.1%) and failure (6.1%). A higher percentage of patients in the alert group received therapeutic intervention within 60 mins after the acute kidney injury alert (28.7% in alert group vs. 7.9% and 10.4% in the pre- and postalert control groups, respectively, p μ .001). In the alert group, more patients received fluid therapy (23.0% vs. 4.9% and 9.2%, p μ .01), diuretics (4.2% vs. 2.6% and 0.8%, p μ .001), or vasopressors (3.9% vs. 1.1% and 0.8%, p μ .001). Furthermore, these patients had a shorter time to intervention (p μ .001). A higher proportion of patients in the alert group showed return to a baseline kidney function within 8 hrs after an acute kidney injury alert "from normal to risk" compared with patients in the control group (p = .048). The real-time alerting of every worsening RIFLE class by the acute kidney injury sniffer increased the number and timeliness of early therapeutic interventions

2016-01-01

We have performed an initial evaluation and testing program to assess the effectiveness of a hydroxyapatite (Ca10(PO4)6(OH)2) permeable reactive barrier and source area treatment to decrease uranium mobility at the Department of Energy (DOE) former Old Rifle uranium mill processing site in Rifle, western Colorado. Uranium ore was processed at the site from the 1940s to the 1970s. The mill facilities at the site as well as the uranium mill tailings previously stored there have all been removed. Groundwater in the alluvial aquifer beneath the site still contains elevated concentrations of uranium, and is currently used for field tests to study uranium behavior in groundwater and investigate potential uranium remediation technologies. The technology investigated in this work is based on in situ formation of apatite in sediment to create a subsurface apatite PRB and also for source area treatment. The process is based on injecting a solution containing calcium citrate and sodium into the subsurface for constructing the PRB within the uranium plume. As the indigenous sediment micro-organisms biodegrade the injected citrate, the calcium is released and reacts with the phosphate to form hydroxyapatite (precipitate). This paper reports on proof-of-principle column tests with Old Rifle sediment and synthetic groundwater.

Remedial action plan and site design for stabilization of the inactive uranium mill tailings sites at Rifle, Colorado: Final report

International Nuclear Information System (INIS)

1990-02-01

This radiologic characterization of tho two inactive uranium millsites at Rifle, Colorado, was conducted by Bendix Field Engineering Corporation (Bendix) for the US Department of Energy (DOE), Grand Junction Projects Office, in accord with a Statement of Work prepared by the DOE Uranium Mill Tailings Remedial Action (UMTRA) Project Technical Assistance Contractor, Jacobs Engineering Group, Inc. (Jacobs). The purpose of this project is to define the extent of radioactive contamination at the Rifle sites that exceeds US Environmental Protection Agency, (EPA) standards for UMTRA sites. The data presented in this report are required for characterization of the areas adjacent to the tailings piles and for the subsequent design of cleanup activities. An orientation visit to the study area was conducted on 31 July--1 August 1984, in conjunction with Jacobs, to determine the approximate extent of contaminated area surrounding tho piles. During that visit, survey control points were located and baselines were defined from which survey grids would later be established; drilling requirements were assessed; and radiologic and geochemical data were collected for use in planning the radiologic fieldwork. The information gained from this visit was used by Jacobs, with cooperation by Bendix, to determine the scope of work required for the radiologic characterization of the Rifle sites. Fieldwork at Rifle was conducted from 1 October through 16 November 1984

The Old Rifle Site is a former vanadium and uranium ore-processing facility located adjacent to the Colorado River and approximately 0.3 miles east of the city of Rifle, CO. The former processing facilities have been removed and the site uranium mill tailings are interned at a disposal cell north of the city of Rifle. However, some low level remnant uranium contamination still exists at the Old Rifle site. In 2002, the United States Nuclear Regulatory Commission (US NRC) concurred with United States Department of Energy (US DOE) on a groundwater compliance strategy of natural flushing with institutional controls to decrease contaminant concentrations in the aquifer. In addition to active monitoring of contaminant concentrations, the site is also used for DOE Legacy Management (LM) and other DOE-funded small-scale field tests of remediation technologies. The purpose of this laboratory scale study was to evaluate the effectiveness of a hydroxyapatite (Ca₁₀(PO₄)₆(OH)₂) permeable reactive barrier and source area treatment in Old Rifle sediments. Phosphate treatment impact was evaluated by comparing uranium leaching and surface phase changes in untreated to PO₄-treated sediments. The impact of the amount of phosphate precipitation in the sediment on uranium mobility was evaluated with three different phosphate loadings. A range of flow velocity and uranium concentration conditions (i.e., uranium flux through the phosphate-treated sediment) was also evaluated to quantify the uranium uptake mass and rate by the phosphate precipitate.

Full Text Available OBJECTIVE: To compare the renal outcome in patients submitted to two different regimens of glycemic control, using the RIFLE criteria to define acute kidney injury. INTRODUCTION: The impact of intensive insulin therapy on renal function outcome is controversial. The lack of a criterion for AKI definition may play a role on that. METHODS: Included as the subjects were 228 randomly selected, critically ill patients engaged in intensive insulin therapyor in a carbohydrate-restrictive strategy. Renal outcome was evaluated through the comparison of the last RIFLE score obtained during the ICU stay and the RIFLE score at admission; the outcome was classified as favorable, stable or unfavorable. RESULTS: The two groups were comparable regarding demographic data. AKI developed in 52% of the patients and was associated with a higher mortality (39.4% compared with those who did not have AKI (8.2% (p60, acute kidney injury and hypoglycemia were risk factors for mortality. CONCLUSION: Intensive insulin therapy and a carbohydrate-restrictive strategy were comparable regarding the incidence of acute kidney injury evaluated using RIFLE criteria.

To assess the association between violence against women inflicted by their partner and the prevalence of chronic malnutrition in their children less than five years old. A secondary cross-sectional analysis of the 2001 Peru Demographic and Health Survey performed in Peru, with national representativeness. The dependent variable was chronic malnutrition in the youngest child under five years old. The independent variables were emotional violence, physical violence (mild or severe) and sexual violence self-report; the violence was inflicted by the mother's last partner or spouse in the last 12 months. Univariate and multivariate analysis was performed, generalized linear models (log-binomial regression) were used, and the nature of the sample was taken into account. Models for socio-demographic and mother-son health variables were adjusted. Prevalence ratios (PR) and confidence intervals were calculated. Data from 5,154 mothers and children were analyzed. The prevalence of chronic malnutrition was 19.8% (CI 95%: 18.1-21.6). In the multivariate analysis, a higher prevalence of chronic malnutrition was found in the children whose mothers had a history of severe physical violence history: PR=1.27% (IC 95%: 1.09-1.48). There was no evidence of association between the prevalence of chronic malnutrition and other kinds of violence inflicted by a partner. The mothers' report of physical violence in the last year was associated with an increased prevalence of chronic malnutrition in children under five years old.

A study of change in muzzle velocity due to freezing and water immersion of .22, long rifle, K. F. cartridges has been presented. A statistical criterion has been formulated to ascertain whether or not a cartridge undergoes a change in muzzle velocity due to a particular treatment. The muzzle velocity data of .22, long rifle, K. F. cartridges, obtained by an electronic timer before and after the various treatments, have been analyzed in the light of this criterion. These cartridges have generally been found to suffer considerable loss in muzzle velocity when immersed in water for three weeks and also when immersed in water for three days and simultaneously cooled to 0 degrees C. The forensic significance of this loss in muzzle velocity has been discussed.

1992-07-01

The Estes Gulch disposal site is approximately 10 kilometers (6 miles) north of the town of Rifle, off State Highway 13 on Federal land administered by the Bureau of Land Management. The Department of Energy (DOE) will transport the residual radioactive materials (RRM) by truck to the Estes Gulch disposal site via State Highway 13 and place it in a partially below-grade disposal cell. The RRM will be covered by an earthen radon barrier, frost protection layers, and a rock erosion protection layer. A toe ditch and other features will also be constructed to control erosion at the disposal site. After removal of the RRM and disposal at the Estes Gulch site, the disturbed areas at all three sites will be backfilled with clean soils, contoured to facilitate surface drainage, and revegetated. Wetlands areas destroyed at the former Rifle processing sites will be compensated for by the incorporation of now wetlands into the revegetation plan at the New Rifle site. The UMTRA Project Office, supported by the Remedial Action Contractor (RAC) and the Technical Assistance Contractor (TAC), oversees the implementation of the MAP. The RAC executes mitigation measures in the field. The TAC provides monitoring of the mitigation actions in cases where mitigation measures are associated with design features. Site closeout and inspection compliance will be documented in the site completion report

The seductive superego: the trauma of self-betrayal.

Science.gov (United States)

Josephs, L

2001-08-01

The author describes a pathological manifestation of the approving superego that functions as a perversely seductive superego. In this process, the seductive superego rationalises and makes ego-syntonic a gratification of forbidden wishes that will result in unconscious punishment. The author argues that the seductive superego torments the self by teasing it with the presence of a tantalising but forbidden object of desire and then by inflicting shame on the self for its timidity, which prevents it from pursuing the object in spite of the dangers. He suggests that the seductive superego inflicts a betrayal trauma upon the self by unconsciously actualising a sado-masochistic fantasy of seduction, surrender and betrayal, along with a humiliating punishment for surrendering.

To determine the pattern of homicidal deaths caused by rifled weapons in Peshawar as regards the parameters of age, gender, place of occurrence and the number and location of injuries on the body. Descriptive study. The study was conducted at the Department of Forensic Medicine and Toxicology, Khyber Medical College, Peshawar, from June 2005 to February 2006. The subjects were selected from victims presenting for autopsy at the Department of Forensic Medicine and Toxicology, Khyber Medical College, Peshawar. One hundred cases were selected where the weapon of offence was a rifled weapon and the manner of death was homicide on the basis of the police inquest, the autopsy and an interview with the relatives of the victim. After the autopsy, the findings were tabulated and analyzed. Homicides predominantly occurred in young males residing in a rural locality. The peak incidence was between 20-29 years in males and in females the age group most prone was 30-39 years. Male to female ratio was 6:1. The chest (33.8%) followed by the head and abdomen were the areas primarily targeted. High velocity automatic weapons are primarily being used to kill young people in rural areas. Prevention can be through strict gun control laws coupled with education and awareness.

Self-injurious behavior as a habit and its treatment.

Science.gov (United States)

Orian, C

1989-10-01

The definition of self-injurious behavior applies to persons who hurt or harm themselves without the motive of suicide or of sexual deviation. The different aspects of self-injurious behavior and the theories explaining them are reviewed. For 5 years a young, intelligent woman had inflicted injuries upon herself with sharp instruments while ostensibly caring for her face and legs. The short-term hypnobehavioral treatment included keeping daily reports of her self-inflicted injuries and of her thoughts while executing them, finding alternative activities to replace her habit, and practicing self-hypnosis once a day. Increasing the level of understanding of her inner conflict and accenting ways of breaking the habit by means of positive autosuggestion proved very effective. The treatment was successful after 13 sessions.

The destabilizing effect of body armour on military rifle bullets.

Science.gov (United States)

Knudsen, P J; Sørensen, O H

1997-01-01

Soft body armour is designed to give protection against fragments and some low velocity bullets but is not designed to stop high velocity rifle bullets. Reports have claimed that soft body armour might disturb the stability of bullets that penetrate it, and that this might increase the size of the lesions. The reason for such an effect might be early yaw of the bullet, so we studied the behaviour of bullets which had passed through soft body armour. A 7.62 x 39 mm AK-47 rifle was fired from a permanent stand using full metal jacketed lead core bullets at a range of 30 m. Soft body armour composed for 14 and 28 layers of aramid fibres (Kevlar) was placed at 90 degrees and 60 degrees to the line of fire. Yaw was measured by the shadowgraph technique and a TERMA Doppler radar. A total of ten shots without body armour, and ten shots with each of the two types of body armour at the two angles were used. The results of the shadowgraph and Doppler radar measurements showed a proportional correlation between the two methods of determining the bullet yaw. The semiquantitative approach of the Doppler radar measurement was in agreement with the more concise measurement using the photographic technique. Velocity loss and loss of spin rate from penetrating 14 or 28 ply Kevlar was negligible. We observed induced instability after penetration of 14 and particularly 28 ply Kevlar, dependence of yaw with respect to the number of layers of Kevlar as well as to the angle of the body armour with respect to the line of fire.

Axial-Symmetry Numerical Approaches for Noise Predicting and Attenuating of Rifle Shooting with Suppressors

Directory of Open Access Journals (Sweden)

Shi-Wei Lo

2011-01-01

Full Text Available The moving bullet out of a rifle barrel is propelled by a fired explosive charge. Subsequently, a disturbed muzzle blast wave is initiated which lasts several milliseconds. In this study, axially symmetric, unsteady, Large Eddy Simulation (LES, and Ffowcs Williams and Hawkins (FWH equations were solved by the implicit-time formulation. For the spatial discretization, second order upwind scheme was employed. In addition, dynamic mesh model was used to where the ballistic domain changed with time due to the motion of bullet. Results obtained for muzzle flow field and for noise recorded were compared with those obtained from experimental data; these two batches of results were in agreement. Five cases of gunshot including one model of an unsuppressed rifle and four models of suppressors were simulated. Besides, serial images of species distributions and velocity vectors-pressure contours in suppressors and near muzzle field were displayed. The sound pressure levels (dB in far field that were post-processed by the fast Fourier transform (FFT were compared. The proposed physical model and the numerical simulations used in the present work are expected to be extended to solve other shooting weapon problems with three-dimensional and complex geometries.

Wounding effects of the AK-47 rifle used by Patrick Purdy in the Stockton, California, schoolyard shooting of January 17, 1989.

1990-09-01

The limited disruption produced in tissue simulant by the rifle and bullets used in the Stockton, California, schoolyard shooting is entirely consistent with the autopsy reports on the five children who died of their wounds. It is also entirely consistent with well-documented battlefield studies and with previous tissue-simulant studies from many laboratories. It is inconsistent with many exaggerated accounts of assault-rifle wounding effects described by the media in the aftermath of this incident. This information should be documented for the historical record. However, the critical reason for correcting the misconceptions produced by media reaction to this incident is to prevent inappropriate gunshot-wound treatment.

Full Text Available This paper presents a design of vibration absorber using spring and rubber for 5.56 mm caliber rifle armored vehicle. Such a rifle is used in a Remote-Controlled Weapon System (RCWS or a turret where it is fixed using a two degree of freedom pan-tilt mechanism. A half car lumped mass dynamic model of armored vehicles was derived. Numerical simulation was conducted using fourth order Runge Kutta method. Various types of vibration absorbers using spring and rubber with different configurations are installed in the elevation element. Vibration effects on horizontal direction, vertical direction and angular deviation of the elevation element was investigated. Three modes of fire were applied i.e. single fire, semi-automatic fire and automatic fire. From simulation results, it was concluded that the parallel configuration of damping rubber type 3, which has stiffness of 980,356.04 (N/m2 and damping coefficient of 107.37 (N.s/m, and Carbon steel spring whose stiffness coefficient is 5.547 x 106 (N/m2 provides the best vibration absorption. 

Self-Referential Processing, Rumination, and Cortical Midline Structures in Major Depression

Science.gov (United States)

Nejad, Ayna Baladi; Fossati, Philippe; Lemogne, Cédric

2013-01-01

Major depression is associated with a bias toward negative emotional processing and increased self-focus, i.e., the process by which one engages in self-referential processing. The increased self-focus in depression is suggested to be of a persistent, repetitive and self-critical nature, and is conceptualized as ruminative brooding. The role of the medial prefrontal cortex in self-referential processing has been previously emphasized in acute major depression. There is increasing evidence that self-referential processing as well as the cortical midline structures play a major role in the development, course, and treatment response of major depressive disorder. However, the links between self-referential processing, rumination, and the cortical midline structures in depression are still poorly understood. Here, we reviewed brain imaging studies in depressed patients and healthy subjects that have examined these links. Self-referential processing in major depression seems associated with abnormally increased activity of the anterior cortical midline structures. Abnormal interactions between the lateralized task-positive network, and the midline cortical structures of the default mode network, as well as the emotional response network, may underlie the pervasiveness of ruminative brooding. Furthermore, targeting this maladaptive form of rumination and its underlying neural correlates may be key for effective treatment. PMID:24124416

Self-referential processing, rumination, and cortical midline structures in major depression

Full Text Available Major depression is associated with a bias towards negative emotional processing and increased self-focus, i.e. the process by which one engages in self-referential processing. The increased self-focus in depression is suggested to be of a persistent, repetitive and self-critical nature and is conceptualised as ruminative brooding. The role of the medial prefrontal cortex in self-referential processing has been previously emphasised in acute major depression. There is increasing evidence that self-referential processing as well as the cortical midline structures play a major role in the development, course and treatment response of major depressive disorder. However, the links between self-referential processing, rumination, and the cortical midline structures in depression are still poorly understood. Here, we reviewed brain imaging studies in depressed patients and healthy subjects that have examined these links. The literature suggests that self-referential processing in major depression is associated with increased activity of the anterior cortical midline structures. Abnormal interactions between the lateralised task-positive network, and the midline cortical structures of the default mode network, as well as the emotional response network, may underlie the pervasiveness of ruminative brooding.

Upper Mustang in the Northern Himalayan range of Nepal is the home of brown bears (Ursusarctos). Low-plant biomass as a result of scanty rainfall in Upper Mustang is a reason for habitat overlap of humans and wild animals. Humans who enter into the wild to collect firewood and graze cattle are liable to wild animal attacks. Such attacks, especially by brown bears, are readily identified by the type of injuries. These are more commonly confined to head and neck regions. Cutting, gnawing and tearing by sharp teeth and claws produces specific pattern of injuries, which are devastating but seldom fatal. This article reports a rare case of brown bear injury inflicted upon a man from the Upper Mustang region in Nepal. © The Author(s) 2016.

Meijer, Karim A; Russo, Russell R; Adhvaryu, Dhaval V

2014-04-01

Synthetic cannabinoids have become a worldwide epidemic because they provide a sometimes legal, easily accessible, and presumably safe alternative to marijuana. Recently published reports have linked acute psychosis, myocardial infarctions, convulsions, self-harm, and even terrorist organizations to these designer substances. This case report outlines the first reported case of Black Diamond, a synthetic cannabis, leading to a self-inflicted burn to the bilateral upper extremities requiring a transradial amputation of the right arm and a toe transfer procedure of the left hand after loss of all digits. The patient presented to the emergency department with self-inflicted fourth-degree burns to the bilateral hands and forearms with second-degree burns of the face, for a total body surface area of 14.5%. The patient was found by firefighters with his hands aflame on his kitchen stove. With no previous medical or psychiatric history and collateral information to confirm the patient's mental status prior to use of Black Diamond, the patient's acute psychotic episode was attributed to Black Diamond. After multiple procedures and a lengthy recovery, the patient completed his post-graduate education and entered the professional world. As orthopedic surgeons, we should be involved in educating the public on the harm of these designer drugs, including self-mutilation. The popularity of synthetic drugs in the United States will continue to present a major challenge to all health care providers. Orthopedists are on the front lines of this epidemic because these drugs push patients into risky, traumatic behavior. Copyright 2014, SLACK Incorporated.

Rogue-Elephant-Inflicted Panfacial Injuries: A Rare Case Report

Directory of Open Access Journals (Sweden)

Santosh Kumar Yadav

2012-01-01

Full Text Available Attacks by elephants, the largest of the “large animals,” produce many fatalities a year. Most attacks are provoked, although rogue elephants are occasionally responsible. Trampling, goring, tossing the individual with the trunk, or crushing with the knees produces the injuries. Injuries from encounters with large animals represent a significant health risk for rural communities. Wild-animal-inflicted maxillofacial injuries are rare, and limited literature is available describing their management. We present a case of severe maxillofacial injuries caused by the attack of a rogue elephant.

Mystery of the First Russian Rifle Naval Guns

Directory of Open Access Journals (Sweden)

Nicholas W. Mitiukov

2015-09-01

Full Text Available In 1859 France completed the first ocean-going ironclad warship, «La Gloire», and changed the definition of naval power completely. Russia, as all the other Powers, found that her most powerful naval gun, the 60-pdr, was insufficient for modern warfare, and realized the future naval armament relied on heavy rifled artillery. Both the Army and Navy began purchasing such cannon from foreign providers until a suitable domestic weapon could be produced. The relationship between the Russian military and Krupp is well known. But there was another provided, the Blakely Ordnance Company in England sold many guns to the Army and Navy, beginning with 8-inch MLR in early 1863 to a large number of 9- and 11-inch guns. Deliveries began in November 1863 and continued until mid-1866. But no sources on the armament of Russian ships and fortresses mentions these guns. What happened to them is a mystery.

Baseline risk assessment of ground water contamination at the Uranium Mill Tailings Sites near Rifle, Colorado. Revision 2

International Nuclear Information System (INIS)

1996-02-01

The U.S. Department of Energy (DOE) Uranium Mill Tailings Remedial Action (UMTRA) Project consists of the Surface Project (Phase I) and the Ground Water Project (Phase II). Under the UMTRA Surface Project, tailings, radioactive contaminated soil, equipment, and materials associated with the former uranium ore processing sites are placed into disposal cells. The cells are designed to reduce radon and other radiation emissions and to prevent further ground water contamination. The Ground Water Project evaluates the nature and extent of ground water contamination resulting from the uranium ore processing activities. Two UMTRA Project sites are near Rifle, Colorado: the Old Rifle site and the New Rifle site. Surface cleanup at the two sites is under way and is scheduled for completion in 1996. The Ground Water Project is in its beginning stages. A risk assessment identifies a source of contamination, how that contamination reaches people and the environment, the amount of contamination to which people or the environment may be exposed, and the health or environmental effects that could result from that exposure. This report is a site-specific document that will be used to evaluate current and future impacts to the public and the environment from exposure to contaminated ground water. This evaluation and further site characterization will be used to determine if action is needed to protect human health or the environment. Human health risk may result from exposure to ground water contaminated from uranium ore processing. Exposure could occur from drinking water obtained from a well placed in the areas of contamination. Furthermore, environmental risk may result from plant or animal exposure to surface water and sediment that have received contaminated ground water

The objective of the present study was to compare the injurious action of three types of the bullets for the pneumatic weapons shot from different distances using the Gamo pump air pistol and the BAM B22-1 pneumatic rifle. The following four kinds of the bullets were tested: "the fireball", "Luman cap 0.3", "Luman Field Target 0.68" and "DIABOLO". It was experimentally shown that the injurious action of the bullets fired from the same distance from the pneumatic weapons depends on the type of both the bullet and the weapon, as well as the properties of the target material. Specifically, the action of bullets fired from the piston pneumatic rifle remained stable whereas that of the bullets shot from the gas-balloon air pistol decreased as the gas was exhausted. The studies by the contact-diffusion method have demonstrated that the entrance bullet holes created by the shots from pneumatic weapons are surrounded by dispersed metal particles which makes it possible to estimate the shooting distance. Moreover, the bullets fired from the pneumatic weapons leave the muzzle face imprint on certain target materials.

Self-Inflicted Trauma Secondary to Local Anaesthesia in Children

Full Text Available Long acting local anaesthetics and inferior alveolar nerve block in children can cause loss of sensation and proprioception in a large area supplied by that particular nerve. Similar to the maxilla in mandible also, adequate level of anaesthesia can be achieved in the desired site of treatment by using a short acting local anaesthetic. Early return of normal sensory feedback after using short acting anaesthetics can be helpful in preventing self-harm.

Anaesthetic Bodies and the Absence of Feeling: Pain and Self-Mutilation in Later Nineteenth-Century Psychiatry

Directory of Open Access Journals (Sweden)

Sarah Chaney

2012-12-01

Full Text Available This paper addresses the overlapping ways in which self-inflicted injury was understood in relation to an absence of pain during the long nineteenth century, arguing that a clear distinction between bodily and mental suffering cannot be made in this period. The medical view that self-infliction of injury must necessarily be pathological is shown to have emerged from earlier philosophical approaches to pain. This was cemented by the formation of a somatic model of self-mutilation, based on the concept of cutaneous anaesthesia, particularly in the work of Wilhelm Griesinger in Germany. In contrast, the words of asylum patients provide a much broader spectrum of ways in which injuries might have been understood. Nonetheless, the meanings attributed generally emphasize self-mutilation as a response to physical, rather than emotional, pain, indicating the widespread nature of physical aetiologies of insanity. Such a somatic approach also permeated psychological models of self-inflicted injury in the late nineteenth and early twentieth centuries, as shown through examination of Richard von Krafft-Ebing’s concept of ‘sexual anaesthesia’, William James’s association of anaesthesia with the absence of emotion, and self-mutilation and fixed ideas in the work of Pierre Janet. The study of self-mutilation thus provides an interesting angle from which to explore the complexity of notions of body and mind, in relation to concepts of pain.

Full Text Available Abstract. Until recently, Penthaleus major (Dugès has not been recognized as an economically significant pest for the cereal crops. After climatic changes, its population began to grow and inflict damages around the world. The aim of this study was to investigate its distribution in Bulgaria and establish whether it presents a danger to the cereal crops. In the autumn of 2015 and the spring of 2016, a monitoring survey was conducted to establish Penthaleus major (Dugès with the cereal crops in Bulgaria. Over 60 sowed fields were investigated from all around the country. Samples were taken to identify the pest. It was established that Penthaleus major (Dugès inflicted harm to the wheat in north-eastern (12-14 mites per stem and south-eastern Bulgaria (6-8 mites per stem. Its density was under the threshold of economic harm. There was not found infestation of barley, rye, oat and triticale. On the field boundaries bordering the areas attacked by the mite were reported the following weeds: Capsella bursa pastoris (L. Medic, Descurania sophia (L. Welb. et Berth, Senecio spp., Sisymbrium orientale Torn., Taraxsacum officinale Weber, Anthemis spp., Bromus arvensis L., Eragrostis pilosa (L. P.B. Lolium temulentum L., which can be habitat for Penthaleus major (Dugès.

-Tertiary(?) Rifle Falls normal fault, that dips southward placing Leadville Limestone adjacent to Eagle Valley and Maroon Formations. Diapiric Eagle Valley Evaporite intruded close to the fault on the down-thrown side and presumably was injected into older strata on the upthrown block creating a blister-like, steeply north-dipping sequence of Mississippian and older strata. Also, removal of evaporite by either flow or dissolution from under younger parts of the strata create structural benches, folds, and sink holes on either side of the normal fault. A prominent dipslope of the Morrison-Dakota-Mancos part of the section forms large slide blocks that form distinctly different styles of compressive deformation called the Elk Park fold and fault complex at different parts of the toe of the slide. The major geologic hazard in the area consist of large landslides both associated with dip-slope slide blocks and the steep slopes of the Eagle Valley Formation and Belden Formation in the northern part of the map. Significant uranium and vanadium deposits were mined prior to 1980.

Full Text Available This report is the case of multiple self-inserted pins and nails in chest and pericardial cavity in a young male suffering from schizophrenia. This act of self-mutilation was done to get relief from burning sensation in chest and palpitations. Review of the relevant literature revealed that self-inflicted intra-cardiac needle injuries occur mainly in young and middle-aged adults suffering from psychiatric disorders, commonly depression, schizophrenia, and substance use disorders. In one-fourth of the patients, it is due to deliberate self-harm. About 70% use a single needle but 30% may use multiple needles. Second attempts are rare. Majority of the patients (85% are managed by surgery and recover from the injury. The condition has a low mortality rate of 5%.

She presented with a painful ulcer on her right lower abdomen. She also presented with multiple scars, skin grafts on the extremities, and a missing left lower leg, the causes for all of which were unexplained. The results of her blood test were normal, except for the hemoglobin level. Histology of the skin biopsy specimen from the ulcer did not show any specific findings. The previous surgeon who had performed the laparoscopic cholecystectomy revealed that surgical wound dehiscence had occurred during her admission. After a body restraint had been applied, the ulcer improved. Medical records indicated that she had been admitted to the department of plastic surgery at our hospital for skin grafting of a leg ulcer. During that admission, she refused to consult with the department of psychiatry, although the staff suspected mental disorders. Therefore, we diagnosed her with cutaneous Munchausen syndrome. After vacuum-assisted closure (VAC therapy had been performed to prevent her from traumatizing the ulcer again, it rapidly became granulated and reepithelialized. Munchausen syndrome is characterized by feigning physical symptoms to seek attention. Patients self-inflict numerous lesions, keep getting admitted to different hospitals, and feign acute illness, usually spectacular diseases.

Waste minimization opportunities at the U.S. Uranium Mill Tailings Remedial Action (UMTRA) Project, Rifle, Colorado, site

Hartmann, G.L.; Arp, S.; Hempill, H.

1993-01-01

At two uranium mill sites in Rifle, Colorado, the US Department of Energy (DOE) Uranium Mill Tailings Remedial Action (UMTRA) Project is removing uranium mill tailings and contaminated subgrade soils. This remediation activity will result in the production of groundwater contaminated with uranium, heavy metals, ammonia, sulfates, and total dissolved solids (TDS). The initial remediation plan called for a wastewater treatment plant for removal of the uranium, heavy metals, and ammonia, with disposal of the treated water, which still includes the sulfates and TDSS, to the Colorado River. The National Pollutant Discharge Elimination (NPDES) permit issued by the Colorado Department of Health for the two Rifle sites contained more restrictive discharge limits than originally anticipated. During the detailed review of alternate treatment systems to meet these more restrictive limits, the proposed construction procedures were reviewed emphasizing the methods to minimize groundwater production to reduce the size of the water treatment facility, or to eliminate it entirely. It was determined that with changes to the excavation procedures and use of the contaminated groundwater for use in dust suppression at the disposal site, discharge to the river could be eliminated completely

Self-mutilations in private-accident-insurance cases.

Science.gov (United States)

Dotzauer, G; Iffland, R

1976-04-21

Self-inflicted injuries can be classified in groups. One group deals with the simulation of illness, another with the occurrence itself and the application of chemical, thermic or mechanical methods. One sector concerns self-mutilation, which, from a psychiatrist's point of view, is interesting. At this time we are more concerned with the problems of proving it. In wartime and even during military service in peace-time soldiers inflict mutilating injuries on themselves. They are motivated by the notion that they will gain benefit from their action. Economic gain plays a role in the case of people who have taken out private accident insurance: self mutilation to simulate the result of an accident. Our investigation into self-mutilation started with an analysis under the following aspects of 123 cases: age, sex, occupation, place of residence, place and time of deed, method employed (weapon used), localisation, single or multiple wound, direction of injury, position of fingers, nature of edges of wound. Whether or not an injury was suffered voluntarily or involuntarily can only be determined with the help of auxiliary facts. It must be clarified whether or not the information given by the injured person ties in with facts concerning the place where the injury was sustained, its position and its direction. The medico-legal expert should not interpret medical findings without relating them to the facts of the case. Indeed, he should start by examining the claimant's account of the accident. To some extent it almost requires the work of a general staff to compare the findings of a careful medical investigation with the injuries themselves. If the injury was inflicted by a certain tool information must be available regarding, for example, the "accident with the saw" together with an assessment of the wounds sustained (utilization of clinical material). Sometimes tests on corpses need to be carried out because these can provide information on mechanical and physical

Firearm discharges produce hazardous levels of impulse noise that can lead to permanent hearing loss. In the present study, we evaluated the effects of suppression, ammunition, and barrel length on AR-15 rifles. Sound levels were measured left/right of a user's head, and 1-m left of the muzzle, per MIL-STD-1474-D, under both unsuppressed and suppressed conditions. Nine commercially available AR-15 rifles and 14 suppressors were used. Suppressors significantly decreased peak dB SPL at the 1-m location and the left ear location. However, under most rifle/ammunition conditions, levels remained above 140 dB peak SPL near a user's right ear. In a subset of conditions, subsonic ammunition produced values near or below 140 dB peak SPL. Overall suppression ranged from 7-32 dB across conditions. These data indicate that (1) suppressors reduce discharge levels to 140 dB peak SPL or below in only a subset of AR-15 conditions, (2) shorter barrel length and use of muzzle brake devices can substantially increase exposure level for the user, and (3) there are significant left/right ear sound pressure differences under suppressed conditions as a function of the AR-15 direct impingement design that must be considered during sound measurements to fully evaluate overall efficacy.

The objective of the present work was to study the morphological features of skin wounds inflicted by joinery hand saws designed for longitudinal, transverse, and mixed sawing. A total of 60 injuries to the thigh skin inflicted by the recurring and reciprocating saw movements were simulated. The hand saws had 5 mm high "sharp" and "blunt"-tipped teeth. The analysis of the morphological features of the wounds revealed differences in their length and depth, shape of edge cuts and defects, and the relief of the walls depending on the sawtooth sharpness and the mode of sawing. It is concluded that morphological features of the wounds may be used to determine the type of the saw, the sharpness of its teeth, the direction and frequency of its movements.

Stunning effect of different rifle-bullets for slaughter of outdoor cattle

Directory of Open Access Journals (Sweden)

Full Text Available The slaughter method via gunshot implies a stunning of cattle by means of a targeted shot from a rifle and is as an alternative to regular slaughter at abattoirs. This method is only permitted under restricted circumstances and if the cattle is held on a pasture all the year. However, there is a considerable lack of specifications regulated by law concerning calibre and bullet-type. In this study, four different calibres, two bullet-types and two different shot placements were investigated with respect to their stunning efficiency. All of the calibres exhibited an entry-energy over 400 J and provided sufficient stunning potential. Yet, only calibre .22 Magnum caused no exit of the bullet out of the scull, which provides higher safety conditions for man and cattle.

The usage small-unmanned aerial vehicles (UAVs) is significantly increasing nowadays. They are being used as a carrier of military spy and reconnaissance devices (taking photos, live video streaming and so on), or as a carrier of potentially dangerous cargo (intended for destruction and killing). Both ways of utilizing the UAV cause the necessity to disable it. From the military point of view, to disable the UAV means to bring it down by a weapon of an ordinary soldier that is the assault rifle. This task can be challenging for the soldier because he needs visually detect and identify the target, track the target visually and aim on the target. The final success of the soldier's mission depends not only on the said visual tasks, but also on the properties of the weapon and ammunition. The paper deals with possible methods of prediction of probability of hitting the UAV targets.

Major self-mutilation (amputation, castration, self-inflicted eye injuries) is frequently associated with psychiatric disorders and/or substance abuse. A 35-year-old man presented with behavioral disturbances of sudden onset after oral cannabis consumption and major self-mutilation (attempted amputation of the right arm, self-enucleation of both eyes and impalement) which resulted in death. During the enquiry, four fragments of a substance resembling cannabis resin were seized at the victim's home. Autopsy confirmed that death was related to hemorrhage following the mutilations. Toxicological findings showed cannabinoids in femoral blood (tetrahydrocannabinol (THC) 13.5 ng/mL, 11-hydroxy-tetrahydrocannabinol (11-OH-THC) 4.1 ng/mL, 11-nor-9-carboxy-THC (THC-COOH) 14.7 ng/mL, cannabidiol (CBD) 1.3 ng/mL, cannabinol (CBN) 0.7 ng/mL). Cannabinoid concentrations in hair (1.5 cm brown hair strand/1 segment) were consistent with concentrations measured in chronic users (THC 137 pg/mg, 11-OH-THC 1 pg/mg, CBD 9 pg/mg, CBN 94 pg/mg). Analysis of the fragments seized confirmed that this was cannabis resin with high levels of THC (31-35%). We discuss the implications of oral consumption of cannabis with a very high THC content.

There is limited information regarding the long-term outcome of inflicted traumatic brain injury (TBI), including shaken infant syndrome. The purpose of this study was to describe the long-term neurologic, behavioral, and cognitive sequelae seen in this population. A cross-sectional and prospective longitudinal study was conducted of 25 children with inflicted TBI in Scotland between 1980 and 1999. After consent was obtained, neurologic and cognitive examinations were performed on all participants and sequentially in the prospective cohort. Two global outcome measures were used: Glasgow Outcome Score (GOS) and Seshia's outcome score. Cognitive outcome was assessed using the Bayley Scales of Infant Development, British Ability Scales, and the Vineland Adaptive Behavior Scales. The mean length of follow-up was 59 months. A total of 68% of survivors were abnormal on follow-up, 36% had severe difficulties and were totally dependant, 16% had moderate difficulties, and 16% had mild difficulties on follow-up. A wide range of neurologic sequelae were seen, including motor deficits (60%), visual deficits (48%), epilepsy (20%), speech and language abnormalities (64%), and behavioral problems (52%). There was a wide range of cognitive abilities: the mean psychomotor index, 69.9 (SD: +/-25.73); and mean mental development index, 74.53 (SD: +/-28.55). Adaptive functioning showed a wide range of difficulties across all domains: communication domain (mean: 76.1; SD: +/-25.4), Daily living skills domain (mean: 76.9; SD: +/-24.3), and socialization domain (mean: 79.1; SD: +/-23.1). Outcome was found to correlate with the Pediatric Trauma Score and the Glasgow Coma Score but did not correlate with age at injury or mechanism of injury. Inflicted TBI has a very poor prognosis and correlates with severity of injury. Extended follow-up is necessary so as not to underestimate problems such as specific learning difficulties and attentional and memory problems that may become apparent only

Analysis of cobbly soils for cobbles-to-fines corrections to radionuclide concentrations at the New Rifle, Colorado, processing site

International Nuclear Information System (INIS)

1994-05-01

A contamination depth and cobbly soil characterization study was performed in November and December 1993 at the Uranium Mill Tailings Remedial Action (UMTRA) Projects's New Rifle, Colorado, processing site. This study was initiated due to a concurrence by the US Nuclear Regulatory Commission (NRC) clarifying that the allowable residual contamination in soil should be averaged over the total mass of the soil volume, including cobbles and gravels (i.e., bulk concentration). The New Rifle processing site has a high percentage of cobbles and gravels underlying the pile and other contaminated areas, which preliminary excavation designs have identified for removal and disposal. The main purpose of this study was to evaluate the relative mass percentage and radionuclide concentrations of cobbles and gravels in order to determine the bulk contamination concentrations, revise the underlying excavation design depths, and improve verification methods. Another important goal of the study was to acquire more accurate contamination depth data (profile) for the subpile material. In summary, this recharacterization study will probably reduce the volume of material for excavation/disposal by several hundred thousand cubic yards and significantly reduce the amount of ground water expected to be pumped out of the excavation during cleanup

Alteration in self-perception is a salient feature in major depression. Hyperactivity of anterior cortical midline regions has been implicated in this phenomenon in depressed adults. Here, we extend this work to depressed adolescents during a developmental time when neuronal circuitry underlying the sense of self matures by using task-based functional magnetic resonance imaging (fMRI) and connectivity analyses. Twenty-three depressed adolescents and 18 healthy controls (HC) viewed positive and negative trait words in a scanner and judged whether each word described them ('self' condition) or was a good trait to have ('general' condition). Self-perception scores were based on participants' endorsements of positive and negative traits during the fMRI task. Depressed adolescents exhibited more negative self-perceptions than HC. Both groups activated cortical midline regions in response to self-judgments compared to general-judgments. However, depressed adolescents recruited the posterior cingulate cortex/precuneus more for positive self-judgments. Additionally, local connectivity of the dorsal medial prefrontal cortex was reduced during self-reflection in depressed adolescents. Our findings highlight differences in self-referential processing network function between depressed and healthy adolescents and support the need for further investigation of brain mechanisms associated with the self, as they may be paramount to understanding the etiology and development of major depressive disorder.

Shell, Duane F.; Soh, Leen-Kiat

2013-12-01

The goal of the present study was to utilize a profiling approach to understand differences in motivation and strategic self-regulation among post-secondary STEM students in major versus required non-major computer science courses. Participants were 233 students from required introductory computer science courses (194 men; 35 women; 4 unknown) at a large Midwestern state university. Cluster analysis identified five profiles: (1) a strategic profile of a highly motivated by-any-means good strategy user; (2) a knowledge-building profile of an intrinsically motivated autonomous, mastery-oriented student; (3) a surface learning profile of a utility motivated minimally engaged student; (4) an apathetic profile of an amotivational disengaged student; and (5) a learned helpless profile of a motivated but unable to effectively self-regulate student. Among CS majors and students in courses in their major field, the strategic and knowledge-building profiles were the most prevalent. Among non-CS majors and students in required non-major courses, the learned helpless, surface learning, and apathetic profiles were the most prevalent. Students in the strategic and knowledge-building profiles had significantly higher retention of computational thinking knowledge than students in other profiles. Students in the apathetic and surface learning profiles saw little instrumentality of the course for their future academic and career objectives. Findings show that students in STEM fields taking required computer science courses exhibit the same constellation of motivated strategic self-regulation profiles found in other post-secondary and K-12 settings.

The goal of the present research was the examination of overlap between 2 research traditions on interpersonal personality traits in major depression. We hypothesized that Blatt's (2004) dimensions of depressive experiences around the dimensions of relatedness (i.e., dependency) and self-definition (i.e., self-criticism) are associated with specific interpersonal problems according to the interpersonal circumplex model (Leary, 1957). In addition, we examined correlations of interpersonal characteristics with depression severity. Analyses were conducted on 283 patients with major depressive disorder combined from 2 samples. Of the patients, 151 participated in a randomized controlled trial in the United States, and 132 patients were recruited in an inpatient unit in Germany. Patients completed measures of symptomatic distress, interpersonal problems, and depressive experiences. Dependency was associated with more interpersonal problems related to low dominance and high affiliation, while self-criticism was associated with more interpersonal problems related to low affiliation. These associations were independent of depression severity. Self-criticism showed high overlap with cognitive symptoms of depression. The findings support the interpersonal nature of Blatt's dimensions of depressive experiences. Self-criticism is associated with being too distant or cold toward others as well as greater depression severity, but is not related to the dimension of dominance. © 2014 Wiley Periodicals, Inc.

Self trust. The nuclear community and particularly nuclear regulators overreact to accidents, this has been the case with the three NPP major accidents. Lowering admissible radiation levels, for example, conveys the wrong message to politicians and the general public, and contributes to enhance mistrust towards nuclear. Industry as well as regulators should mature and act with self respect, since the scientific bases of regulation are very solid and should be trusted. Lessons learned should be seriously pursued in spite of the 'uneven playing field'. Obviously safety continues as the main priority, but paranoid reactions from the nuclear professionals could destroy the future of nuclear power. (author)

The Rifle quadrangle extends from the Grand Hogback monocline into the southeastern part of the Piceance basin. In the northeastern part of the map area, the Wasatch Formation is nearly vertical, and over a distance of about 1 km, the dip decreases sharply from about 70-85o to about 15-30o toward the southwest. No evidence of a fault in this zone of sharp change in dip is observed but exposures in the Shire Member of the Wasatch Formation are poor, and few marker horizons that might demonstrate offset are distinct. In the central part of the map area, the Shire Member is essentially flat lying. In the south and southwest part of the map area, the dominant dip is slightly to the north, forming an open syncline that plunges gently to the northwest. Evidence for this fold also exists in the subsurface from drill-hole data. According to Tweto (1975), folding of the early Eocene to Paleocene Wasatch Formation along the Grand Hogback reqired an early Eocene age for the last phase of Laramide compression. We find the attitude of the Wasatch Formation to be nearly horizontal, essentially parallel to the overlying Anvil Points Member of the Eocene Green River Formation; therefore, we have no information that either confirms or disputes that early Eocene was the time of the last Laramide event. Near Rifle Gap in the northeast part of the map area, the Mesaverde Group locally dips about 10o less steeply than the overlying Wasatch Formation, indicating that not only had the formation of the Hogback monocline not begun by the time the Wasatch was deposited at this locality, but the underlying Mesaverde Group was locally tilted slightly toward the present White River uplift. Also the basal part of the Atwell Gulch Member of the Wasatch Formation consists of fine-grained mudstones and siltstones containing sparse sandstone and rare conglomerates, indicating that the source of sediment was not from erosion of the adjacent Upper Cretaceous Mesaverde Group.

This study examines the relationships between explicit and implicit self-esteem and self-referent memory biases in depression. We specifically tested the hypothesis that implicit self-esteem would influence depression-related memory biases via its association with explicit self-esteem. Self-esteem was assessed in patients with a current Major Depressive Disorder (MDD; n=38) and in a control group of participants who had never experienced depression (ND; n=40) by using explicit (Rosenberg Self-esteem Questionnaire) and implicit (Go/No-go Association Task) measures. A self-referent processing task of negative and positive adjectives was used to assess memory bias. Our analyses revealed that participants diagnosed with MDD showed lower levels of both explicit and implicit self-esteem in comparison to ND participants. MDD compared to ND participants also recalled a greater number of depressed self-referent adjectives and lower recall of positive self-referent information. Mediation analyses showed an indirect effect of explicit self-esteem on the relationship between implicit self-esteem and depression-related memory biases in the MDD group. These findings suggest an association between implicit and explicit self-esteem in depression that may result in negative cognitive processing, as reflected by self-referent memory biases.

Full Text Available  Ischemic stroke secondary to aortic dissection is not uncommon. We present a patient with left hemiplegia secondary to Stanford type A aortic dissection extending to the supra-aortic vessels, which was precipitated by rifle butt recoil chest injury. The diagnosis of aortic dissection was delayed due to various factors. Finally, the patient underwent successful Bentall procedure with complete resolution of symptoms. This case emphasizes the need for caution in the use of firearms for recreation and to take precautions in preventing such incidents. In addition, this case illustrates the need for prompt cardiovascular physical examination in patients presenting with stroke.

2016-01-01

The present article deals with the problem of forensic medical diagnostics of the injuries inflicted inside the passenger car compartment during motor vehicle accidents. The authors place special emphasis on the fact of a significant increase in the number of road traffic accidents (RTA) with such consequences throughout the world. The modern automobile industry pays much attention to the enhancement of the car safety features by significantly improving the design of passenger compartments. It accounts for a change in the traditional character of the injuries to both the driver and the passengers resulting from motor vehicle accidents. This, in turn, creates difficulties for the forensic medical experts as regards personality identification of the subjects who happened to be inside the car at the moment of the collision especially in the case of unascertainable circumstances of the accident and/or the involvement of several victims. The authors describe peculiarities of the injuries inflicted inside the passenger car compartment during road traffic accidents including such that result from bringing the driver and the passengers closer to the construction elements of the car (stage I), their direct contact with these elements (stage II), and subsequent displacement (stage III).

The Rifle IFRC continued to make excellent progress during the last 12 months. As noted above, a key field experiment (Best Western) was performed during 2011 as a logical follow-on to the Super 8 field experiment preformed in 2010. In the Super 8 experiment, we successfully combined desorption and bioreduction and deployed a number of novel tracer techniques to enhance our ability to interpret the biogeochemistry of the experiment. In the Best Western experiment, we used the same experimental plot (Plot C) as was used for Super 8. The overarching objective of the Best Western field experiment was to compared the impacts of abiotic vs. biotic increases in alkalinity and to assess the mass of the sorbed pool of U(VI) at Rifle at the field scale. Both of these objectives were met. Preliminary analysis of the data indicate that the underlying biogeochemical data sets were obtained that will support a mechanistic understanding of the underlying processes, including remarkable insight into previously unrecognized microbial processes taking place during acetate amendment of the subsurface for a second time.

Clay Mineralogy of AN Alluvial Aquifer in a Mountainous, Semiarid Terrain, AN Example from Rifle, Colorado

Alluvial sediments deposited along the Colorado River corridor in the semi-arid regions of central to western Colorado can be important hosts for legacy contamination including U, V, As and Se. These alluvial sediments host aquifers which are thought to provide important "hot spots" and "hot moments" for microbiological activity controlling organic carbon processing and fluxes in the subsurface. Relatively little is known about the clay mineralogy of these alluvial aquifers and the parent alluvial sediments in spite of the fact that they commonly include lenses of silt-clay materials. These lenses are typically more reduced than coarser grained materials, but zones of reduced and more oxidized materials are present in these alluvial aquifer sediments. The clay mineralogy of the non-reduced parent alluvial sediments of the alluvial aquifer located in Rifle, CO (USA) is composed of chlorite, smectite, illite, kaolinite and quartz. The clay mineralogy of non-reduced fine-grained materials at Rifle are composed of the same suite of minerals found in the sediments plus a vermiculite-smectite intergrade that occurs near the bottom of the aquifer near the top of the Wasatch Formation. The clay mineral assemblages of the system reflect the mineralogically immature character of the source sediments. These assemblages are consistent with sediments and soils that formed in a moderately low rainfall climate and suggestive of minimal transport of the alluvial sediments from their source areas. Chlorite, smectite, smectite-vermiculite intergrade, and illite are the likely phases involved in the sorption of organic carbon and related microbial redox transformations of metals in these sediments. Both the occurrence and abundance of chlorite, smectite-vermiculite, illite and smectite can therefore exert an important control on the contaminant fluxes and are important determinants of biogeofacies in mountainous, semiarid terrains.

It is difficult to distinguish whether children's head injuries are due to physical abuse or unintentional accidents. However, in the literature, medical findings specific to infant physical abuse were identified. Thus, we developed diagnostic criteria for inflicted head injury (IHI) and assessed its validity. Subjects were collected from all patients who were less than two years old when they visited National Center for Child Health (NCCHD) and Development and underwent head CT scan to assess head trauma from March 1, 2002 to December 31, 2005. Diagnostic criteria for IHI were developed based on definitions of Duhaime et al (1992) and Reece et al (2001). Validity of diagnosis criteria was assessed by comparing the official report to the Child Guidance Center (CGC) from NCCHD to the disposition decided by the CGC. Two-hundred and sixty cases were collected and diagnosed. There was a 86.5% match of the number of cases which were diagnosed as IHI or non-IHI using the IHI diagnostic criteria with official reports to CGC from NCCHD. Among the cases which were diagnosed as presumptive IHI and also reported to the CGC, 20 cases (83.3%) were regarded as abused cases by the CGC. The diagnostic criteria for IHI were valid and would be useful for pediatricians not to condone inflicted head injury. (author)

Suicide by burning and other forms of self-injurious behaviors which involve burning are sometimes considered to have religious overtones. The ritual death of widows upon their husband's funeral pyre is closely associated with Hindu beliefs. Buddhists have used self-immolation as a form of protest. The Judaeo-Christian traditions have imagery of fire as cleansing and purifying; there is also secular imagery associating fire with images of condemnation and evil. Previous studies have described religiosity as a common theme among survivors. The present study describes the ways in which persons who inflicted self-injurious behaviors through burning, including attempted suicide, imagine the Divinity and use religious language to give meaning to their experience.

Fragmentation of the lead core of conventional wildlife hunting rifle bullets causes contamination of the target with lead. The community of scavenger species which feed on carcasses or viscera discarded by hunters are regularly exposed to these lead fragments and may die by acute or chronic lead intoxication, as demonstrated for numerous species such as white-tailed eagles (Haliaeetus albicilla) where it is among the most important sources of mortality. Not only does hunting with conventional ammunition deposit lead in considerable quantities in the environment, it also significantly delays or threatens the recovery of endangered raptor populations. Although lead-free bullets might be considered a suitable alternative that addresses the source of these problems, serious reservations have been expressed as to their ability to quickly and effectively kill a hunted animal. To assess the suitability of lead-free projectiles for hunting practice, the wounding potential of conventional bullets was compared with lead-free bullets under real life hunting conditions. Wound dimensions were regarded as good markers of the projectiles' killing potential. Wound channels in 34 killed wild ungulates were evaluated using computed tomography and post-mortem macroscopical examination. Wound diameters caused by conventional bullets did not differ significantly to those created by lead-free bullets. Similarly, the size of the maximum cross-sectional area of the wound was similar for both bullet types. Injury patterns suggested that all animals died by exsanguination. This study demonstrates that lead-free bullets are equal to conventional hunting bullets in terms of killing effectiveness and thus equally meet the welfare requirements of killing wildlife as painlessly as possible. The widespread introduction and use of lead-free bullets should be encouraged as it prevents environmental contamination with a seriously toxic pollutant and contributes to the conservation of a wide

The effects of problem-based learning on the self-efficacy and attitudes of beginning biology majors

Science.gov (United States)

Rajab, Adel Mohammad

The problem of low persistence of science majors has resulted in calls for changes in undergraduate instruction toward environments that foster positive self-efficacy among beginning science majors. Low science self-efficacy and poor attitudes toward science may contribute to high attrition rates of science majors. Classroom environments that foster positive self-efficacy development include pedagogies that promote authentic learning contexts and involve collaborative learning teams. Problem-based learning (PBL) is an instructional model that attempts to create both conditions and may provide every source of information needed for the development of self-efficacy (i.e., mastery experiences, vicarious experiences, verbal persuasion, and physiological states) as postulated by Albert Bandura. The degree to which these sources of self-efficacy are delivered to individuals within a PBL group may depend on how the group members interact and how students perceive the PBL process itself. This study examined the development of biology self-efficacy and attitudes among biology majors in a PBL setting and in a traditional lecture-based setting. Specifically, this project investigated changes in students' biology self-efficacy beliefs, mediating aspects of PBL in self-efficacy development, the relationship between PBL processes and group collective efficacy, the predictive nature of entering self-efficacy levels on attitudes toward PBL and mid-term grades, and changes in student attitudes toward biology. The study design was quasi-experimental and included quantitative pre- and post-surveys, qualitative interviews, and classroom observations. Findings revealed that students enrolled in a PBL class exhibited greater gains in biology self-efficacy and were likely to report more favorable attitudes toward biology compared to students enrolled in a traditional class. The aspects of PBL that most accounted for these findings were students' ownership of the learning process, their

Injection of organic carbon into the subsurface as an electron donor for bioremediation of redox-sensitive contaminants like uranium often leads to mineral transformation and biomass accumulation, both of which can alter the flow field and potentially bioremediation efficacy. This work combines reactive transport modeling with a column experiment and field measurements to understand the biogeochemical processes and to quantify the biomass and mineral transformation/accumulation during a bioremediation experiment at a uranium contaminated site near Rifle, Colorado. We use the reactive transport model CrunchFlow to explicitly simulate microbial community dynamics of iron and sulfate reducers, and their impacts on reaction rates. The column experiment shows clear evidence of mineral precipitation, primarily in the form of calcite and iron monosulfide. At the field scale, reactive transport simulations suggest that the biogeochemical reactions occur mostly close to the injection wells where acetate concentrations are highest, with mineral precipitate and biomass accumulation reaching as high as 1.5% of the pore space. This work shows that reactive transport modeling coupled with field data can bean effective tool for quantitative estimation of mineral transformation and biomass accumulation, thus improving the design of bioremediation strategies.

Space exploration launch costs on the order of $10,000 per pound provide an incentive to seek ways to reduce structural mass while maintaining structural function to assure safety and reliability. Damage-tolerant structural systems provide a route to avoiding weight penalty while enhancing vehicle safety and reliability. Self-healing polymers capable of spontaneous puncture repair show promise to mitigate potentially catastrophic damage from events such as micrometeoroid penetration. Effective self-repair requires these materials to quickly heal following projectile penetration while retaining some structural function during the healing processes. Although there are materials known to possess this capability, they are typically not considered for structural applications. Current efforts use inexpensive experimental methods to inflict damage, after which analytical procedures are identified to verify that function is restored. Two candidate self-healing polymer materials for structural engineering systems are used to test these experimental methods.

Air-powered rifles shoot ball bearings with enough kinetic energy to penetrate skin and fracture underlying bones. In addition, there are reports of these ball bearings embolizing within the vascular network, causing serious injuries such as ischemic stroke with resultant blindness. The severity of these complications warrants occasional removal of these foreign bodies; however, they can be difficult to localize. In this case report, we describe the use of a magnetic port finder, a sterilizable tool used in breast reconstruction, to localize the foreign body in situ. We believe that this tool is effective at locating ferrous foreign bodies precisely, allowing for surgical retrieval while minimizing damage to surrounding tissue.

“It's Just a Matter of Time:” Lessons from Agency and Community Responses to Polar Bear-inflicted Human Injury

Directory of Open Access Journals (Sweden)

Aimee L Schmidt

2018-01-01

Full Text Available Bear-inflicted human injuries or deaths are often widely publicised, controversial, and evoke substantial social responses that articulate public expectations about bear management. In this paper, we examine how local people and management agencies (i.e. Manitoba Conservation, Parks Canada, and the Town of Churchill responded to a polar bear-inflicted human injury in Churchill, Manitoba, Canada. On November 1st, 2013, two people in Churchill were badly mauled by a polar bear. The incident shocked the community, highlighted problems such as a lack of bear safety education, and led to reviews of institutional policies for preventing polar bear-human conflicts. We used qualitative analysis methods to describe what is said (about polar bears, about people, and about management and what is done (changes in behaviours and changes in policies/practices when someone is attacked by a polar bear in Churchill. Results show that polar bear management agencies in Churchill respond remarkably well to errors in procedure, but are often unable to address the many underlying systematic drivers of polar bear-human conflict. Hence, managerial reactions to bear-human conflicts are successful at addressing the proximate cause of the problem, but offer few long-term solutions.

Alkaloid berberine is widely used for the treatment of diarrhea and other diseases. Many laboratory studies showed that it exhibits anti-proliferative activity against a wide spectrum of cancer cells in culture. In this report we studied the mechanisms underlying the inhibitory effects of berberine on human osteosarcoma cells and on normal osteoblasts. The inhibition was largely attributed to cell cycle arrest at G1 and G2/M, and to a less extent, to apoptosis. The G1 arrest was dependent on p53, as G1 arrest was abolished in p53-deficient osteosarcoma cells. The induction of G1 arrest and apoptosis was accompanied by a p53-dependent up-regulation of p21 and pro-apoptotic genes. However, the G2/M arrest could be induced by berberine regardless of the status of p53. Interestingly, DNA double-strand breaks, as measured by the phosphorylation of H2AX, were remarkably accumulated in berberine-treated cells in a dose-dependent manner. Thus, one major mechanism by which berberine exerts its growth-inhibitory effect is to inflict genomic lesions on cells, which in turn trigger the activation of p53 and the p53-dependent cellular responses including cell cycle arrest and apoptosis

What factors play a role in preventing self-immolation?Results from a case-control study in Iran

Directory of Open Access Journals (Sweden)

Hosein Karim

2015-07-01

Full Text Available Abstract: Background: To investigate factors related to prevention of self-immolation in west of Iran. Methods: In a case-control study, 30 consecutive cases of deliberate self-inflicted burns admitted to the regional burn center (Imam Khomeini hospital in Kermanshah province, Iran were compared with controls selected from the community and matched by sex, age,district-county of residence, and rural vs urban living environment. The following characteristics relevant to preventing self immolation were collected from all cases and controls: main domestic fuel used in the household, awareness about complications of burn injuries, and use of counseling services. Results: Descriptive analyses revealed that kerosene was the main domestic fuel in the household for 83% of cases. Not surprisingly, the main means of self-immolation in 93% of the patients was kerosene, with other fuels such as petrol and domestic gas used in remaining cases. The majority of cases and controls were aware of the potential complications of burn injuries. Use of counseling services was more common in controls. Conclusions: All three aspects of preventing self-immolation – having kerosene and other fuels in the home, being aware of the complications of burn injuries, and using counseling services were present in both the cases and controls. This suggests a large portion of residents in rural Iran are potential self-immolation victims. Increasing preventive strategies may reduce risk of suicide by self-immolation.

Perfectionistic Self-Presentation and Suicide in a Young Woman with Major Depression and Psychotic Features

Flett, Gordon L.; Hewitt, Paul L.

2014-01-01

A woman in her midtwenties with a history of major depressive disorder and a recent major depressive episode with mood-congruent psychotic features died by suicide. Two weeks before her death, she demonstrated exceptional elevations on the nondisplay of imperfection factor of Hewitt and Flett's Perfectionistic Self-Presentation Scale. Perfectionism and especially perfectionistic self-presentation have been strongly associated with suicide across several populations, accounting for unique variance in suicidality beyond depression and hopelessness. Yet interpersonal facets of perfectionism are not recognized as clinical risk factors for suicide. There is also a paucity of research on perfectionism in relation to psychotic symptoms. This case account illustrates the role of perfectionistic self-presentation in suicides that occur seemingly without warning and, to our knowledge, this is the first examination of perfectionistic self-presentation and suicide in a case where psychotic features occurred. This study, though single case-based, draws attention to perfectionism and perfectionistic self-presentation and their potential roles in suicide, especially when accompanied by other risk factors. Future research in this area may elucidate the role of perfectionism in suicide, singularly and in the context of a comprehensive clinical risk assessment, demonstrating whether perfectionism confers information about suicide risk beyond known clinical risk factors.

Changes of explicitly and implicitly measured self-esteem in the treatment of major depression: evidence for implicit self-esteem compensation.

Self-esteem has been claimed to be an important factor in the development and maintenance of depression. Whereas explicit self-esteem is usually reduced in depressed individuals, studies on implicitly measured self-esteem in depression exhibit a more heterogeneous pattern of results, and the role of implicit self-esteem in depression is still ambiguous. Previous research on implicit self-esteem compensation (ISEC) revealed that implicit self-esteem can mirror processes of self-esteem compensation under conditions that threaten self-esteem. We assume that depressed individuals experience a permanent threat to their selves resulting in enduring processes of ISEC. We hypothesize that ISEC as measured by implicit self-esteem will decrease when individuals recover from depression. 45 patients with major depression received an integrative in-patient treatment in the Psychosomatic University Hospital Bonn, Germany. Depression was measured by the depression score of the Hospital Anxiety and Depression Scale (HADS-D). Self-esteem was assessed explicitly using the Rosenberg Self-Esteem Scale (RSES) and implicitly by the Implicit Association Test (IAT) and the Name Letter Test (NLT). As expected for a successful treatment of depression, depression scores declined during the eight weeks of treatment and explicit self-esteem rose. In line with our hypothesis, both measures of implicit self-esteem decreased, indicating reduced processes of ISEC. It still remains unclear, under which conditions there is an overlap of measures of implicit and explicit self-esteem. The results lend support to the concept of ISEC and demonstrate the relevance of implicit self-esteem and self-esteem compensation for the understanding of depression. Copyright © 2014 Elsevier Inc.

A 2-year-old girl presented to casualty with a right knee effusion after apparently minor trauma. Inflicted injury was suspected and full forensic coagulation studies were performed which revealed a mild deficiency of factor VIII. Screening of the exons and intron/exon boundaries of F8 gene indicated that the child appeared to be homozygous for the missense mutation c.5123G>A (p.Arg1708His) in exon 14 of the F8 gene. This mutation has been reported to be associated with mild haemophilia A. The possibility of hemizygosity had been masked by the test kit employed but referral to the genetics service and subsequent array CGH resulted in a diagnosis of Turner syndrome. © 2011 Blackwell Publishing Ltd.

To describe the occurrence of finger autophagia in 5 persons with traumatic spinal cord injury and to present a discussion of putative causes and potential treatments. Minor self-mutilating actions, such as nail biting and hair pulling, are common in humans and usually benign. In some circumstances, these behaviors are associated with obsessive-compulsive personality traits. In humans, self-injurious biting behaviors are well described in the setting of mental retardation and psychosis and in persons with Lesch-Nyhan syndrome. Rare cases of human autophagia in persons with intact cognition have been reported, most commonly in the setting of acquired nervous system lesions. After spinal cord injury, it has been suggested that this behavior constitutes a human variant of animal autotomy and a response to neuropathic pain. Case presentation narrative. Photographic and radiological study, administration of Yale-Brown Obsessive-Compulsive Scale (YBOCS). In 5 patients with complete tetraplegia, pain in the hands was present in only one instance. The severity of autoamputation varied from minor to extreme. In all cases, damage was confined to analgesic body parts. In 3 cases, autophagia behavior was discovered in progress. Treatments included pharmacotherapy, counseling, and behavioral therapy, with mixed results. All patients were intelligent, willing to discuss their issues, and able to identify conditions of stress and isolation in their lives. Mild preinjury obsessive-compulsive behaviors, such as nail biting, were universal. On the YBOCS, only 1 patient scored in a range indicative of mild obsessive-compulsive symptomatology. This group exhibited heterogeneous medical, social, and cultural characteristics. A link between pain and self-injurious behavior could not be demonstrated. This behavior may be viewed as an extreme variant of nail biting, with potential ominous complications. Treatment strategies have been employed with mixed results.

The effects of Fe-oxidizing microorganisms on post-biostimulation permeability reduction and oxidative processes at the Rifle IFRC site

Energy Technology Data Exchange (ETDEWEB)

Chan, Clara Sze-Yue [Univ. of Delaware, Newark, DE (United States)

Fe oxidation and biomineral formation is important in aquifers because the highly-reactive oxides can control the mobility of nutrients (e.g. phosphate, C) and metals (e.g. arsenic, uranium). Mineral formation also has the potential to affect hydrology, depending on the volume and distribution in pore spaces. In this exploratory study, we sought to understand how microbial Fe-oxidizers and their biominerals affect, and are affected by groundwater flow. As part of work at the Rifle aquifer in Colorado, we initially hypothesized that Fe-oxidizers were contributing to aquifer clogging problems associated with enhanced bioremediation. To demonstrate the presence of Fe-oxidizers in the Rifle aquifer, we enriched FeOM from groundwater samples, and isolated two novel chemolithotrophic, microaerophilic Fe-oxidizing Betaproteobacteria, Hydrogenophaga sp. P101 and Curvibacter sp. CD03. To image cells and biominerals in the context of pores, we developed a “micro-aquifer,” a sand-filled flow-through culture chamber that allows for imaging of sediment pore space with multiphoton confocal microscopy. Fe oxide biofilms formed on sand grains, demonstrating that FeOM produce Fe oxide sand coatings. Fe coatings are common on aquifer sands, and tend to sequester contaminants; however, it has never previously been shown that microbes are responsible for their formation. In contrast to our original hypothesis, the biominerals did not clog the mini-aquifer. Instead, Fe biofilm distribution was dynamic: they grew as coatings, then periodically sloughed off sand grains, with some flocs later caught in pore throats. This has implications for physical hydrology, including pore scale architecture, and element transport. The sloughing of coatings likely prevents the biominerals from clogging wells and aquifers, at least initially. Although attached biomineral coatings sequester Fe-associated elements (e.g. P, As, C, U), when biominerals detach, these elements are transported as particles

Reappraisal is an adaptive emotion regulation strategy while the role of self-perspective in reappraisal process of depressed patients is largely unknown in terms of goals (valence/arousal) and tactics (detachment/immersion). In this study, 12 depressed individuals and 15 controls were scanned with MRI during which they either attend naturally to emotional stimuli, or adopt detachment/immersion strategy. Behaviorally, no group differences in self-reported emotion regulation effectiveness were found. In addition, we observed that (1) patients were less able to downregulate amygdala activation with recruitment of more dorsal lateral prefrontal cortex (dlPFC) when adopting detachment strategy regardless of valence, and this preserved ability to regulate emotion was inversely associated with severity of symptoms; (2) patients had deficits in upregulating amygdala activation when adopting immersion strategy, with less inferior frontal gyrus (IFG) activation and strengthening coupling of dlPFC and ventral medial prefrontal cortex (vmPFC) with amygdala; (3) comparison between groups yielded that patients showed stronger vmPFC activation under either self-detached or self-immersed condition. In conclusion, impaired modulatory effects of amygdala in depressed patients are compensated with strengthening cognitive control resources, with dissociable effects for different self-perspectives in reappraisal. These results may help clarify the role of self-perspective underlying reappraisal in major depression.

Children suffering from thalassemia have higher levels of depression and lower levels of self-concept. The aim of this study was to determine if group play therapy could significantly increase self-concept among children with thalassemia major ages 7 to 11 years old in teaching hospitals of Golestan province, Iran, in 2012. In this randomized, controlled clinical trial, 60 children with thalassemia major were randomly assigned to intervention (30 children) and control (30 children) groups. The intervention included eight 45 to 60 minute sessions during four weeks, during which the intervention group received group play therapy. The control group received no interventions. Self-concept was measured three times using the Piers-Harris children's self-concept scale: before, immediately after, and a month after the intervention. For the intervention group, results showed that the mean self-concept score was significantly higher at the second point in time compared to the baseline (P 0.05). The results showed that group play therapy improves self-concept in children suffering from thalassemia major.

The suicide risk among young adults is related to multiple factors; therefore, it is difficult to predict and prevent suicidal behavior. We conducted the present study to reveal the most important factors relating to suicidal ideation in Japanese university students with major depressive episodes (MDEs) of major depressive disorder (MDD). The subjects were 30 Japanese university students who had MDEs of MDD, and were aged between 18 and 26 years old. They were divided into two groups - without suicide risk group (n=15), and with suicide risk group (n=15) - based on the results of the Mini-International Neuropsychiatric Interview. Additionally, healthy controls were recruited from the same population (n=15). All subjects completed the self-assessment scales including the Beck Depression Inventory 2nd edition (BDI-II), the Beck Hopelessness Scale (BHS), Rosenberg's Self-Esteem Scale (RSES), and SF-36v2™ (The Medical Outcomes Study 36-item short-form health survey version 2), and they were all administered a battery of neuropsychological tests. The RSES score of the suicide risk group was significantly lower than the RSES score of the without suicide risk group, whereas the BDI-II score and the BHS score were not significantly different between the two groups. The mean social functioning score on the SF-36v2 of the with suicide risk group was significantly lower than that of the without suicide risk group. The individual's self-esteem and social functioning may play an important role in suicide risk among young adults with MDEs of MDD.

BACKGROUND The alarming incidence of self- burning provoked to set up a multidisciplinary preventive program to decrease the incidence and complications of this harmful issue. This study investigated the incidence and the preventive measures in self-burn in Fars Province, southern Iran. METHODS This study was a longitudinal prospective design on trend of self-inflicted burn injuries in Fars province after setting up a regional multidisciplinary preventive plan (2009-2012). RESULTS From 18862 admitted patients, 388 (2%) committed self-burning. While the incidence showed a constant decrease in proportion of suicidal cases among all admitted patients (2.5% to 1.6%). The mean age of self-burning victims ranged from 28.3±10.8 to 30.3±11.7 years. The female victims comprised 67.4% of all suicidal burn patients (Female to male ratio: 2.18). The leading causes of suicide commitment were familial conflicts (75.6%) and psychological problems (16.7%) CONCLUSION It is crucial to continue the regional preventive programs and pave the way to set up national, and even international collaborations to alleviate relevant financial, social, cultural and infrastructural difficulties in order to have lower incidence for this dramatic issue.

Inviting pain? Pain, dualism and embodiment in narratives of self-injury.

Science.gov (United States)

Chandler, Amy

2013-06-01

The role of pain in the practice of self-injury is not straightforward. Existing accounts suggest that self-injury does not cause 'physical' pain, however self-injury is also said to alleviate 'emotional' pain by inflicting 'physical' pain. This article explores these tensions using sociological theories regarding the socio-cultural and subjective nature of pain. Analysis derives from in-depth, life-story interviews carried out in the UK with people who had self-injured. Findings contribute to on-going debates within social science regarding the nature of pain. Participants' narratives about pain and self-injury both drew on and challenged dualistic models of embodiment. I suggest that self-injury offers a unique case on which to extend existing theoretical work, which has tended to focus on pain as an unwanted and uninvited entity. In contrast, accounts of self-injury can feature pain as a central aspect of the practice, voluntarily invited into lived experience. © 2013 The Author.

Full Text Available The study was focussed on the relationships between ethnic self-esteem and various indicators of intergroup attitudes in a representative sample of adult population of Estonia (N=1142. Attitudinal variables that discriminated most between persons with high and low ethnic self-esteem were identified. Among Estonians ethnic self-esteem was related to positive ingroup bias, readiness for outgroup contact, perceived threat from the outgroup, attitudes to non-Estonian minority, and attitudes toward minority integration. Among non-Estonians ethnic self-esteem was related to readiness for outgroup contact, ethnic sterotypes, and various attitudes towards minority integration. An attempt was made to reconstruct the system of intergroup attidues of prototypical persons with high and low ethnic selfesteem and to describe psychological implications of high and low ethnic self-esteem for members of majority and minority groups. Various theoretical models (social identity theory, integrated threat theory, social dominane theory were used for interpretation of the results.

To clarify the causes of the increased incidence of injuries inflicted by wild animals in Kashmir, and to suggest preventive measures. A retrospective study reviewed records of these injuries. Data were collected from the hospital in Srinagar and from the Wildlife Protection Department of Kashmir. A total of 203 attacks (26 deaths and 177 near-fatal injuries) were recorded from January 2005 to October 2007, involving 145 (71.5%) male and 58 (28.5%) female victims. The attacking animal was a black bear in 104 (51.2%), a leopard in 18 (8.8%), a wolf in 7 (3.4%) and unidentified in 74 (36.4%) cases; 130 (64%) of these attacks occurred in southern Kashmir. The steady increase in human population in areas close to jungle results in deforestation and destruction of wildlife habitat. The reduction in monkeys and deer (the staple food of leopards) causes these dangerous predators to search for food in the areas occupied by humans, who may then be attacked. Treatment of these cases requires a multidisciplinary approach, including an orthopaedic surgeon, plastic surgeon, microbiologist and psychiatrist, to achieve best cosmetic and functional results.

Endocrine dysfunction is common after accidental traumatic brain injury (TBI). Prevalence of endocrine dysfunction after inflicted traumatic brain injury (iTBI) is not known. The aim of this study was to examine endocrinopathy in children after moderate-to-severe iTBI. Children with previous iTBI (n=14) were evaluated for growth/endocrine dysfunction, including anthropometric measurements and hormonal evaluation (nocturnal growth hormone [GH], thyrotropin surge, morning and low-dose adrenocorticotropin stimulated cortisol, insulin-like growth factor 1, IGF-binding protein 3, free thyroxine, prolactin [PRL], and serum/urine osmolality). Analysis used Fisher's exact test and Wilcoxon's rank-sum test, as appropriate. Eighty-six percent of subjects had endocrine dysfunction with at least one abnormality, whereas 50% had two or more abnormalities, significantly increased compared to an estimated 2.5% with endocrine abnormality in the general population (p<0.001). Elevated prolactin was common (64%), followed by abnormal thyroid function (33%), short stature (29%), and low GH peak (17%). High prolactin was common in subjects with other endocrine abnormalities. Two were treated with thyroid hormone and 2 may require GH therapy. In conclusion, children with a history of iTBI show high risk for endocrine dysfunction, including elevated PRL and growth abnormalities. This effect of iTBI has not been well described in the literature. Larger, multi-center, prospective studies would provide more data to determine the extent of endocrine dysfunction in iTBI. We recommend that any child with a history of iTBI be followed closely for growth velocity and pubertal changes. If growth velocity is slow, PRL level and a full endocrine evaluation should be performed.

Economics of paternalism: the hidden costs of self-commanding strategies

Christophe Salvat

2015-11-01

Full Text Available The paper proposes an economic assessment of paternalism by comparing different alternative responses to dynamically inconsistent behaviors consecutive to hyperbolic discounting. Two main types of action are possible, self-commanding strategies and paternalism The first category includes personal rules and pre-commitment The second can be subcategorized between coercive and non-coercive forms of paternalism, which are respectively associated (although it is debatable with legal paternalism and with ‘nudges’. Despite being self-inflicted, self-commanding strategies are actually not cost free and can result in a dramatic cutback of people’s freedom of choice. Likewise, legal paternalism can, on occasion, be less harmful than personal rules or pre-commitment; similarly, nudges can be more invasive and less effective than their proponents want us to believe. The aim of this paper is not to propose any standardized form of response to irrational behavior (whatever that may mean but to argue, on the contrary, that every case should be individually appraised. Individual situations can be remedied by self-commanding strategies or by paternalistic policies, either in isolation or in combination.

An overly negative self-schema is a proposed cognitive mechanism of major depressive disorder (MDD). Self-schema - one's core conception of self, including how strongly one believes one possesses various characteristics - is part of semantic memory (SM), our knowledge about concepts and their relationships. We used the N400 event-related potential (ERP) - elicited by meaningful stimuli, and reduced by greater association of the stimulus with preceding context - to measure association strength between self-concept and positive, negative, and neutral characteristics in SM. ERPs were recorded from MDD patients (n=16) and controls (n=16) who viewed trials comprising a self-referential phrase followed by a positive, negative, or neutral adjective. Participants' task was to indicate via button-press whether or not they felt each adjective described themselves. Controls endorsed more positive adjectives than did MDD patients, but the opposite was true for negative adjectives. Patients had smaller N400s than controls specifically for negative adjectives, suggesting that MDD is associated with stronger than normal functional neural links between self-concept and negative characteristics in SM.

Full Text Available Investigating the factors related to suicide is crucial for suicide prevention. Psychiatric disorders, gender, socioeconomic status, and catastrophic illnesses are associated with increased risk of suicide. Most studies have typically focused on the separate influences of physiological or psychological factors on suicide-related behaviors, and have rarely used national data records to examine and compare the effects of major physical illnesses, psychiatric disorders, and socioeconomic status on the risk of suicide-related behaviors.To identify the characteristics of people who exhibited suicide-related behaviors and the multiple factors associated with repeated suicide-related behaviors and deaths by suicide by examining national data records.This is a cohort study of Taiwan's national data records of hospitalized patients with suicide-related behaviors from January 1, 1997, to December 31, 2010.The study population included all people in Taiwan who were hospitalized with a code indicating suicide or self-inflicted injury (E950-E959 according to the International Classification of Disease, Ninth Revision, Clinical Modification.Self-poisoning was the most common method of self-inflicted injury among hospitalized patients with suicide-related behaviors who used a single method. Those who were female, had been hospitalized for suicide-related behaviors at a younger age, had a low income, had a psychiatric disorder (i.e., personality disorder, major depressive disorder, bipolar disorder, schizophrenia, alcohol-related disorder, or adjustment disorder, had a catastrophic illness, or had been hospitalized for suicide-related behaviors that involved two methods of self-inflicted injury had a higher risk of hospitalization for repeated suicide-related behaviors. Those who were male, had been hospitalized for suicide-related behaviors at an older age, had low income, had schizophrenia, showed repeated suicide-related behaviors, had a catastrophic illness

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

The effects of majority versus minority source status on persuasion: a self-validation analysis.

Horcajo, Javier; Petty, Richard E; Briñol, Pablo

2010-09-01

The present research proposes that sources in the numerical majority (vs. minority) can affect persuasion by influencing the confidence with which people hold their thoughts in response to the persuasive message. Participants received a persuasive message composed of either strong or weak arguments that was presented by a majority or a minority source. Consistent with the self-validation hypothesis, we predicted and found that the majority (vs. minority) status of the source increased the confidence with which recipients held their thoughts. As a consequence, majority (vs. minority) sources increased argument quality effects in persuasion when source status information followed message processing (Experiment 1). In contrast, when the information regarding source status preceded (rather than followed) the persuasive message, it validated the perception of the position advocated, reducing message processing. As a consequence of having more confidence in the position advocated before receiving the message, majority (vs. minority) sources reduced argument quality effects in persuasion (Experiment 2). Finally, Experiment 3 isolated the timing of the source status manipulation, revealing that sources in the numerical majority (vs. minority) can increase or decrease persuasion to strong arguments depending on whether source status is introduced before or after processing the message.

Full Text Available Background Thalassemia is considered an important public health problem worldwide, especially in developing and poor countries. Although several advanced techniques have been developed for prevention of thalassemia in the recent years, many adolescents and youths are still living with this disease. Independence from parents, decisions about high-risk behaviors, uncovering the identity, and adapting to mental and physical effects of the disease occur together in adolescents. Objectives This study was conducted to explore challenges of self-management empowerment in adolescents and youths with major thalassemia. Materials and Methods This was a descriptive-exploratory study. The study population consisted of adolescents and youths with major thalassemia who had medical records in the Bushehr Thalassemia Center, affiliated with Bushehr University of Medical Sciences. The study samples were purposively selected. Demographic information questionnaire and empowerment questionnaire were used to collect data from the semistructured interview. We analyzed qualitative data by content analysis method and quantitative data by descriptive (mean, standard deviation and analytical (Student's t-test, ANOVA and Pearson’s correlation coefficient statistical methods, using the statistical software SPSS 18. Results In qualitative part of the study, data from semistructured in-depth interviews with 15 participants were coded and summarized in five themes including: 1 awareness of personal changes; 2 need for adaptation; 3 maintaining independence and self-management; 4 uncovering the identity and role playing; and 5 sense of control and satisfaction. Results of the quantitative part showed that the overall score of participants on empowerment was 92.46 of 149 scores, which showed a moderate situation in the empowerment of these individuals. In addition, the empowerment score showed no statistically significant correlation with demographic characteristics

Electron donor amendment for bioremediation often results in precipitation of secondary minerals and the growth of biomass, both of which can potentially change flow paths and the efficacy of bioremediation. Quantitative estimation of precipitate and biomass distribution has remained challenging, partly due to the intrinsic heterogeneities of natural porous media and the scarcity of field data. In this work, we examine the effects of physical and geochemical heterogeneities on the spatial distributions of mineral precipitates and biomass accumulated during a biostimulation field experiment near Rifle, Colorado. Field bromide breakthrough data were used to infer a heterogeneous distribution of hydraulic conductivity through inverse transport modeling, while the solid phase Fe(III) content was determined by assuming a negative correlation with hydraulic conductivity. Validated by field aqueous geochemical data, reactive transport modeling was used to explicitly keep track of the growth of the biomass and to estimate the spatial distribution of precipitates and biomass. The results show that the maximum mineral precipitation and biomass accumulation occurs in the vicinity of the injection wells, occupying up to 5.4vol.% of the pore space, and is dominated by reaction products of sulfate reduction. Accumulation near the injection wells is not strongly affected by heterogeneities present in the system due to the ubiquitous presence of sulfate in the groundwater. However, accumulation in the down-gradient regions is dominated by the iron-reducing reaction products, whose spatial patterns are strongly controlled by both physical and geochemical heterogeneities. Heterogeneities can lead to localized large accumulation of mineral precipitates and biomass, increasing the possibility of pore clogging. Although ignoring the heterogeneities of the system can lead to adequate prediction of the average behavior of sulfate-reducing related products, it can also lead to an

Non-fatal suicide attempt by intentional stab wound: Clinical management, psychiatric assessment, and multidisciplinary considerations

Directory of Open Access Journals (Sweden)

James M Badger

2012-01-01

Full Text Available Background: Suicide by means of self-inflicted stab wounds is relatively uncommon and little is known about this population and their management. Materials and Methods: Retrospective review of adult trauma patients admitted to our Level-1 trauma center between January 2005 and October 2009 for management of non-fatal, self-inflicted stab wounds. Results: Fifty-eight patients were evaluated with self-inflicted stab wounds. Four patients died due to their injuries (mortality, 7%. Of the non-fatal stab wounds, 78% were male ranging in age from 19-82 (mean: 45 years. The most common injury sites were the abdomen (46%, neck (33%, and chest (20%. In terms of operative interventions, 56% of abdominal operations were therapeutic, whereas 100% of neck and chest operations were therapeutic. When assessing for suicidal ideation, 44 patients (81% admitted to suicidal intentions whereas 10 patients (19% described "accidental" circumstances. Following psychiatric evaluation, 8 of the 10 patients with "accidental injuries" were found to be suicidal. Overall, 54 patients (98% met criteria for a formal psychiatric diagnosis with 48 patients (89% necessitating inpatient or outpatient psychiatric assistance at discharge. Conclusions: Compared to previous reports of stab wounds among trauma patients, patients with self- inflicted stab wounds may have a higher incidence of operative interventions and significant injuries depending on the stab location. When circumstances surrounding a self-inflicted stabbing are suspicious, additional interviews by psychiatric care providers may uncover a suicidal basis to the event. Given the increased incidence of psychiatric illness in this population, it is imperative to approach the suicidal patient in a multidisciplinary fashion.

A self-diagnostic monitoring system is a system that has the ability to measure various physical quantities such as temperature, pressure, or acceleration from sensors scattered over a mechanical system such as a power plant, in order to monitor its various states, and to make a decision about its health status. We have developed a self-diagnostic monitoring system for an air-operated valve system to be used in a nuclear power plant. In this study, we have tried to improve the self-diagnostic monitoring system to increase its reliability. We have implemented three different machine learning algorithms, i.e., logistic regression, an artificial neural network, and a support vector machine. After each algorithm performs the decision process independently, the decision-making module collects these individual decisions and makes a final decision using a majority vote scheme. With this, we performed some simulations and presented some of its results. The contribution of this study is that, by employing more robust and stable algorithms, each of the algorithms performs the recognition task more accurately. Moreover, by integrating these results and employing the majority vote scheme, we can make a definite decision, which makes the self-diagnostic monitoring system more reliable.

In this study, we have tried to improve the self-diagnostic monitoring system to increase its reliability. We have implemented three different machine learning algorithms, i.e., logistic regression, an artificial neural network, and a support vector machine. After each algorithm performs the decision process independently, the decision-making module collects these individual decisions and makes a final decision using a majority vote scheme. With this, we performed some simulations and presented some of its results. The contribution of this study is that, by employing more robust and stable algorithms, each of the algorithms performs the recognition task more accurately. Moreover, by integrating these results and employing the majority vote scheme, we can make a definite decision, which makes the self-diagnostic monitoring system more reliable

In the present study it was investigated whether boredom promotes eating and if so, whether this effect likely reflects an increased drive for rewarding stimulation (positive reinforcement) or more plainly the drive to escape boredom (negative reinforcement). In the latter case, the valence of the stimulation should not matter and people might even be willing to look for negative stimulation, for instance to hurt oneself, just to escape boredom. In two parallel experiments, it was tested whether induced boredom promotes the consumption of chocolate (Experiment 1) and whether participants likewise are more inclined to self-administer electrocutaneous stimuli (Experiment 2). In both experiments, a total of 30 participants attended two separate sessions watching a documentary for 1 h (neutral condition) and a monotonous repetition of a single clip from the same documentary for 1 h (boring condition), in balanced order. During Experiment 1, participants had free access to M&Ms and during Experiment 2 participants could freely self-administer brief electrical shocks. It was found that participants ate more M&Ms when bored but also that they more readily self-administered electrical shocks when bored. It is concluded that eating when bored is not driven by an increased desire for satisfying incentive stimulation, but mainly by the drive to escape monotony. Copyright © 2014 Elsevier Ltd.

The Role of Self-Blaming Moral Emotions in Major Depression and Their Impact on Social-Economical Decision Making

OpenAIRE

Pulcu, Erdem; Zahn, Roland; Elliott, Rebecca

2013-01-01

People with major depressive disorder (MDD) are more prone to experiencing moral emotions related to self-blame, such as guilt and shame. DSM-IV-TR recognises excessive or inappropriate guilt as one of the core symptoms of current MDD, whereas excessive shame is not part of the criteria for MDD. However, previous studies specifically assessing shame suggested its involvement in MDD. In the first part of this review, we will consider literature discussing the role of self-blaming moral emotion...

Previous experiments at the Rifle, Colorado Integrated Field Research Challenge (IFRC) site demonstrated that field-scale addition of acetate to groundwater reduced the ambient soluble uranium concentration. In this report, sediment samples collected before and after acetate field addition were used to assess the active microbes via {sup 13}C acetate stable isotope probing on 3 phases [coarse sand, fines (8-approximately 150 {micro}m), groundwater (0.2-8 {micro}m)] over a 24-day time frame. TRFLP results generally indicated a stronger signal in {sup 13}C-DNA in the 'fines' fraction compared to the sand and groundwater. Before the field-scale acetate addition, a Geobacter-like group primarily synthesized {sup 13}C-DNA in the groundwater phase, an alpha Proteobacterium primarily grew on the fines/sands, and an Acinetobacter sp. and Decholoromonas-like OTU utilized much of the {sup 13}C acetate in both groundwater and particle-associated phases. At the termination of the field-scale acetate addition, the Geobacter-like species was active on the solid phases rather than the groundwater, while the other bacterial groups had very reduced newly synthesized DNA signal. These findings will help to delineate the acetate utilization patterns of bacteria in the field and can lead to improved methods for stimulating distinct microbial populations in situ.

Ravi Kumar Chittoria

2014-01-01

Full Text Available Camphor is a waxy white sublimating chemical derived from natural as well as synthetic sources and widely used in various communities worldwide for a number of medicinal, culinary, and religious reasons. Camphor is burnt as an offering to God in many religious communities. We report three incidences of self inflicted injury from burning camphor on the palm resulting in full thickness burns. Non-suicidal self-injury is socially unacceptable destruction or alteration of body tissue when there is no suicidal intent or pervasive developmental disorder and we have explored an association between this and burn injury. This report also highlights the unique social and cultural pattern of this burn injury and the importance of psycho-therapeautic help for these victims.

2018-02-21

Despite growing interest in the temporal dynamics of Major Depressive Disorder (MDD), we know little about the intra-day fluctuations of key symptom constructs. In a study of momentary experience, the Experience Sampling Method captured the within-day dynamics of negative affect, positive affect, self-esteem, passive suicidality, and tiredness across clinical MDD (N= 31) and healthy control groups (N= 33). Ten symptom measures were taken per day over 6 days (N= 2231 observations). Daily dynamics were modeled via intra-day time-trends, variability, and instability in symptoms. MDD participants showed significantly increased variability and instability in negative affect, positive affect, self-esteem, and suicidality. Significantly different time-trends were found in positive affect (increased diurnal variation and an inverted U-shaped pattern in MDD, compared to a positive linear trend in controls) and tiredness (decreased diurnal variation in MDD). In the MDD group only, passive suicidality displayed a negative linear trend and self-esteem displayed a quadratic inverted U trend. MDD and control participants thus showed distinct dynamic profiles in all symptoms measured. As well as the overall severity of symptoms, intra-day dynamics appear to define the experience of MDD symptoms. Copyright © 2018 Elsevier B.V. All rights reserved.

Gender Differences in Self-Efficacy and Sense of Class and School Belonging for Majors in Science, Technology, Engineering, and Mathematics (STEM) Disciplines

Science.gov (United States)

Hogue, Barbara A.

Research into women's underrepresentation in science, technology, engineering, and mathematics (STEM) disciplines has become a topic of interest due to the increasing need for employees with technical expertise and a shortage of individuals to fill STEM jobs. The discrepancy in women's representation between STEM and other fields cannot adequately be explained by factors such as women's need to balance work and family (medicine and law are both extremely demanding careers), women's fear of competition (admissions into medical and law schools are highly competitive), or women's inability to excel in science (e.g., entry into medicine requires excellent achievement in the basic sciences). The purpose of this study is to gain a deeper understanding of the role and/or impact a sense of belonging has inside and outside of STEM classrooms. Research questions focused on the role and/or impact of belonging contributes to students' self-efficacy beliefs as a STEM major. Bandura's self-efficacy theory serves as the theoretical framework. Data sources include close-ended surveys of 200 sophomore- and junior-level college students majoring in a STEM discipline. A quantitative exploratory approach allowed participants' responses to be analyzed using both correlation and multiple regression analyses to understand whether a student's sense of belonging is associated with his or her self-efficacy beliefs. Findings suggested that positive support systems impact students' self-efficacy and play a role in fostering students' motivation and decision to major in STEM disciplines. This study contributes to positive social change by providing empirical evidence faculty and administrators may use to promote university-based STEM support programs reflecting the impact belonging has on students' self-efficacy and potentially increasing the number of students majoring in STEM disciplines.

Rats were exposed to 6 Gy whole body γ-ray irradiation from a 60 Co source followed by light radiation burn (15% TBSA, full thickness burn) from a 5 kw bromo-tungsten lamp. The effect of auto-skin grafting on invasive bacterial infection of wound in the rats with combined radiation-burn injury was studied, In the control group inflicted with combined radiation-burn injury but without skin grafting, bacteria were found on and in the eschars at 24th hour after injury, and in the subeschar tissue on 3rd day. Tremendous bacterial multiplication occurred from 7th to 15th day, and the amount of bacteria in the internal organs increased along with the increase of subeschar infection. At the same time, no bacterial infection was found in internal organs in auto-skin grafted group at 24th hour after injury. The results show that skin grafting can decrease or prevent bacterial infection in both subeschar tissue and internal organs

To investigate short- and long-term effects of major organisational change on minor psychiatric disorder and self-rated health for women and men in different employment grades. Minor psychiatric disorder and self-rated health among 6710 British civil servants (1993 women and 4717 men) in three employment grades from the Whitehall II study were examined from 1985 to 1988 under stable employment conditions. The short-term effects of organisational change were investigated in 1991-1993 after a time of major restructuring aiming at increasing the influence of market forces in the civil service and the long-term effects were investigated in 1997-1999. Those who had experienced organisational change and those who anticipated organisational change reported more negative short-term health effects (minor psychiatric disorder and poor self-rated health) compared with those who reported no change. No major differences were found depending on employment grade or gender. The negative health effects had diminished during 1997-1999 for those who reported that a major change had happened before 1991-1993. Those who anticipated an organisational change in 1991-1993 still reported more ill-health in 1997-1999 (both minor psychiatric disorder and self-reported health) than those in the comparison group. The results indicate that organisational change affects employees' health negatively in the short term but also that it is possible to recover from such negative effects. As it was not possible to discern any definite difference between the gender and grades, the results point at the importance of working proactively to implement organisational change for women and men at all levels.

Hildebrand, E; Hitzer, K; Püschel, K

2006-03-01

A 50-year-old surgeon was working with his electrical circle saw as a do-it-yourselfer. He was alone, nobody witnessed his mishap when he amputated his left index finger. He claimed high financial compensation from two accident insurance companies because of his disability. A long series of medical expertises followed. The juridical procedures took 12 years in total. All higher authorities had to deal with the forensic medical implications. Finally, the high court (Bundesgerichtshof) decided that the complainant would receive no compensation because he gave two very different descriptions. Concerning the reconstruction of the accident, the first version was unlikely from a biomechanical point of view. The decision of the court was solely based on the violation of the obligation to give a clear presentation of the course of events (Obliegenheitsverletzung).

2014-04-01

The authors examined the clinical characteristics of homeless patients presenting to emergency departments (EDs) in the United States, with a focus on unintentional and intentional injury events and related comorbid conditions. The study included a nationally representative sample of patients presenting to EDs with data obtained from the 2007 through 2010 National Hospital Ambulatory Medical Care Survey (NHAMCS). Descriptive and analytical epidemiologic analyses were employed to examine injuries among homeless patients. Homeless persons made 603,000 visits annually to EDs, 55% of which were for injuries, with the majority related to unintentional (52%) and self-inflicted (23%) injuries. Multivariate logistic regression analyses revealed that homeless patients had a higher odds of presenting with injuries related to unintentional (odds ratio [OR]=1.4. 95% confidence interval [CI]=1.1 to 1.9), self-inflicted (OR=6.0, 95% CI=3.7 to 9.5), and assault (OR=3.0, 95% CI=1.5 to 5.9) injuries. A better understanding of the injuries affecting homeless populations may provide medical and public health professionals insight into more effective ways to intervene and limit further morbidity and mortality related to specific injury outcomes. © 2014 by the Society for Academic Emergency Medicine.

Deliberate self-injury functions and their clinical correlates among adolescent psychiatric inpatients.

Radziwiłłowicz, Wioletta; Lewandowska, Magdalena

2017-04-30

The aim of the study was to analyze the relationships between clinical variables (the severity of depression symptoms, feelings towards the body, dissociation, number and type of traumatic events) and deliberate self-injury functions. Moreover, we investigated whether the of group self-mutilating adolescents is internally diverse in terms of how important individual functions of self-mutilation are, and whether the subgroups singled out by these functions differ between each other in terms of clinical variables. The Inventory of Statements about Self-Injury was used. Characterizations of examined individuals and other research tools are included in our previous article (year, issue, pages). Associated with negative feelings towards the body are the functions of self-injuries (anti-dissociation, self-punishment) that can be described as interpersonal. High levels of depression symptoms (self-depreciation included) are mainly associated with the self-injury functions: self-punishment, anti-dissociation, establishing interpersonal boundaries. Affect regulation becomes more important as a function of self-inflicted injuries in cases of biological dysregulation and intense dissociative symptoms. The adolescents psychiatric inpatients are internally diverse in terms of dominant functions of self-injuries, which can be categorized into intra- and interpersonal. Intrapersonal functions dominate when an individual experiences severe depression, dissociative symptoms, and negative feelings towards the body. In cases of moderate intensity of depression, dissociative symptoms and negative feelings towards the body, both intrapersonal and interpersonal functions of self-mutilation are similarly important. Further research is required to explain the lowest severity of depression symptoms, dissociative symptoms and negative feelings towards the body co-occurs with no awareness of self-injuries functions.

Phase Preference by Active, Acetate-Utilizing Bacteria at the Rifle, CO Integrated Field Research Challenge Site

2011-01-01

Uranium contaminated groundwaters are a legacy concern for the U.S. Department of Energy. Previous experiments at the Rifle, Colorado Integrated Field Challenge (IFC) site have demonstrated that field-scale addition of acetate to groundwater reduces the ambient soluable uranium concentration, sequestering the radionuclide as uraninite. However, questions remain regarding which microorganism(s) are consuming this acetate and if active groundwater microorganisms are different from active particle-associated bacteria. In this report, 13-C acetate was used to assess the active microbes that synthesize DNA on 3 size fractions (coarse sand, fines (8-approximately 150 micron), groundwater (0.2-8 micron)) over a 24 -day time frame. Results indicated a stronger signal from 13-C acetate associated with the 'fines' fraction compared with smaller amounts of 13-C uptake on the sand fraction and groundwater samples during the SIP incubations. TRFLP analysis of this 13-C-labeled DNA, indicated 31+ 9 OTU's with 6 peaks dominating the active profiles (166, 187, 210, 212, and 277 bp peaks using MnlI). Cloning/sequencing of the amplification products indicated a Geobacter-like group (187, 210, 212 bp) primarily synthesized DNA from acetate in the groundwater phase, an alpha Proteobacterium (166 bp) primarily grew on the fines/sands, and an Acinetobacter sp. (277 bp) utilized much of the 13C acetate in both groundwater and particle-associated phases. These findings will help to delineate the acetate utilization patterns of bacteria during field-scale acetate addition and can lead to improved methods for stimulating distinct microbial populations in situ.

The association between social capital measures and self-reported health among Muslim majority nations.

Science.gov (United States)

Kim, Harris Hyun-soo

2014-10-01

Much evidence suggests that social capital (e.g. networks, trust, organizational memberships) has a significant effect on self-reported health. Previous research, however, has focused primarily on Western countries. The current research seeks to remedy this problem by investigating the association between multiple social capital indicators and subjective health in a novel empirical setting. The data come from the Comparative Values Survey of Islamic Countries (1999-2006) which consists of probabilistic samples from Muslim majority nations. Three-way multilevel analysis is used to examine the social determinants of health. Statistical results from hierarchical linear modeling shows that frequent contact with strong and intermediate ties (i.e. family members and friends, respectively) is significant, while interaction with weak ties (coworkers) has no association. General trust and trust in the central government are also significantly related to subjective health, as is trust in religious authority, albeit in an inverse way. This study calls for a more contingent view of the relationship between social capital and self-reported health. Future research needs to take this into consideration in hypothesizing and testing the potential health benefits of social capital.

Pipeline Structural Damage Detection Using Self-Sensing Technology and PNN-Based Pattern Recognition

International Nuclear Information System (INIS)

Lee, Chang Gil; Park, Woong Ki; Park, Seung Hee

2011-01-01

In a structure, damage can occur at several scales from micro-cracking to corrosion or loose bolts. This makes the identification of damage difficult with one mode of sensing. Hence, a multi-mode actuated sensing system is proposed based on a self-sensing circuit using a piezoelectric sensor. In the self sensing-based multi-mode actuated sensing, one mode provides a wide frequency-band structural response from the self-sensed impedance measurement and the other mode provides a specific frequency-induced structural wavelet response from the self-sensed guided wave measurement. In this study, an experimental study on the pipeline system is carried out to verify the effectiveness and the robustness of the proposed structural health monitoring approach. Different types of structural damage are artificially inflicted on the pipeline system. To classify the multiple types of structural damage, a supervised learning-based statistical pattern recognition is implemented by composing a two-dimensional space using the damage indices extracted from the impedance and guided wave features. For more systematic damage classification, several control parameters to determine an optimal decision boundary for the supervised learning-based pattern recognition are optimized. Finally, further research issues will be discussed for real-world implementation of the proposed approach

Ocular nonsuicidal self-injury in a teenager.

A 14-year-old male teen presented with unilateral episcleritis, unresponsive to topical and systemic corticosteroid therapy, without a history of ocular trauma or evidence for systemic diseases. The presence of foreign bodies in the conjunctival mucus of the hyperemic fornix has been noticed during one of the follow-up examinations. The toxicological analysis of conjunctival mucus revealed the presence of ethylene glycolmonomethyl ether and triethilene glicolebuthyl ether, used as solvents in nail polish removers and all-purpose cleaners. An unexpected etiology of chemical self-inflicted episcleritis was determined. The teen was admitted to a psychological assessment, after which a psychotherapeutic treatment was recommended. Episcleritis is characterized by the acute onset of ocular pain and redness, with a frequent recurrent and stressful course. Since it can be associated with life-threatening systemic vasculitides, a prompt, aggressive immunosuppressive therapy may be considered, both for the ocular inflammation and for the underlying systemic condition. Rarely episcleritis does not improve despite topical and systemic therapy, administered in a stepladder way. The reported teenager case needed a complex multidisciplinary approach to achieve the correct diagnosis and to avoid unnecessary treatments. In the case of recognized "nonsuicidal self-injury," a psychological evaluation is strongly recommended, to identify and address underlying neuropsychiatric problems.

This study investigated the relationship between perceived mate value discrepancy (i.e., the difference between an individual's mate value and their partner's mate value) and perceived frequency of mate retention performed by an individual relative to his or her partner. In two studies, participants in long-term, exclusive, sexual, heterosexual relationships reported their own, and their partner's, mate value and mate retention. Samples included 899 community members (Study 1) and 941 students and community members (Study 2). In Study 1, we documented that individuals with higher self-perceived short-term mate value, and who perceive their partner to have lower (vs. higher) short-term mate value, perform less frequent Benefit-Provisioning mate retention, controlling for the partner's Benefit-Provisioning mate retention. In Study 2, we documented that individuals who perceive that they could less easily replace their partner, and who perceive their partner could more (vs. less) easily replace them, perform more frequent mate retention (Benefit-Provisioning and Cost-Inflicting), controlling for the partner's mate retention. These results highlight the importance of assessing perceived discrepancies in mate value (notably, regarding the replaceability of self and partner with another long-term mate) and perceived mate retention behaviors of self, relative to partner, between men and women in long-term relationships. © 2016 Wiley Periodicals, Inc.

Studies have reliably identified an association between suicide attempts and executive functions such as decision making (DM) and inhibitory control (IC) in patients with mood disorders. As such, the present study aimed to investigate the association between inhibition, DM, impulsivity and the history of suicide attempts in individuals with bipolar (BD) or major depressive disorder (MDD), identifying which assessment instruments may be most strongly associated with suicide in clinical samples. The sample included 80 control subjects and two groups of patients with BD and MDD, matched by age and education (26 with a history of suicide attempts [MD+], and 26 with no such history [MD-]). Participants completed behavioral and self-report measures of DM and IC, which were compared between groups using ANCOVA, followed by logistic regression for patients with mood disorders only, and the presence or absence of a history of suicide as the outcome. Cognitive performance did not differ between groups. The MD+ group showed significantly higher motor and attentional impulsivity on the BIS-11 than the MD- and control groups. A regression analysis containing these scores showed that motor impulsivity was the only significant predictor of a history of suicide (OR = 1.14; 95%CI 1.00-1.30). Self-reported motor impulsivity was a significant predictor of suicide. These findings underscore the importance of self-report measures in neuropsychological assessment, and their contributions to the management and prognosis of patients with mood disorders. Lastly, they point to the role of impulsivity as a target for interventions and public policy on suicide prevention. Copyright © 2018 Elsevier Inc. All rights reserved.

This hypothesis is based on published studies showing elevated blood lead concentrations in subsistence hunter populations, retention of ammunition residues in the tissues of hunter-killed animals, and systemic, cognitive, and behavioral disorders associated with human lead body burdens once considered safe. Our objective was to determine the incidence and bioavailability of lead bullet fragments in hunter-killed venison, a widely-eaten food among hunters and their families. We radiographed 30 eviscerated carcasses of White-tailed Deer (Odocoileus virginianus shot by hunters with standard lead-core, copper-jacketed bullets under normal hunting conditions. All carcasses showed metal fragments (geometric mean = 136 fragments, range = 15-409 and widespread fragment dispersion. We took each carcass to a separate meat processor and fluoroscopically scanned the resulting meat packages; fluoroscopy revealed metal fragments in the ground meat packages of 24 (80% of the 30 deer; 32% of 234 ground meat packages contained at least one fragment. Fragments were identified as lead by ICP in 93% of 27 samples. Isotope ratios of lead in meat matched the ratios of bullets, and differed from background lead in bone. We fed fragment-containing venison to four pigs to test bioavailability; four controls received venison without fragments from the same deer. Mean blood lead concentrations in pigs peaked at 2.29 microg/dL (maximum 3.8 microg/dL 2 days following ingestion of fragment-containing venison, significantly higher than the 0.63 microg/dL averaged by controls. We conclude that people risk exposure to bioavailable lead from bullet fragments when they eat venison from deer killed with standard lead-based rifle bullets and processed under normal procedures. At risk in the U.S. are some ten million hunters, their families, and low

The aim of the study was to analyze relationships between the variables: severity of depression symptoms, feelings towards one's own body, dissociation, the number and type of traumatic life events experienced by adolescents who engage in deliberate self-injury and are psychiatrically hospitalized. We examined 60 patients aged 13-17 (M = 15.48, SD = 1.19). More than a half (55%) were diagnosed with a mixed disturbance of emotions and conduct, 23.5% with depressive behavior disorders, 10% were diagnosed a depressive episode. The research tools: a socio-demographic survey; original Feelings Towards the Body Questionnaire created on the basis of Tomkiewicz's description; Kovacs's CDI; Scharfetter's Ego-Psychopathology questionnaire. The examined individuals have negative feelings toward their bodies, more than half of them experience severe depression symptoms. There are links between traumatic events, dissociation, body image and the severity of depression symptoms. The strongest links were found: between dissociation vis-a-vis the severity of depression symptoms and the feelings towards one's body; and between the severity of depression symptoms and the feelings towards one's body. Two thirds of the examined individuals attempted suicide. Various forms of direct self-destructive behaviors very often occur simultaneously. It also provokes reflection about the conditions under which self-inflicted injury does (or does not) prevent suicide attempts. Self-mutilation along with the interaction between clinical variables may form a self-destruction syndrome in various mental disorders and contribute to clinical pictures of these disorders, this should be taken into account in diagnosing and treatment of adolescents.

Individual social capital has been recognized as having an important role for health and well-being. We tested the hypothesis that poor social capital increases internalized stigma and, in turn, can reduce empowerment among people with major depressive disorder (MDD). This is a cross-sectional multisite study conducted on a sample of 516 people with MDD in 19 European countries. Structural Equation Models were developed to examine the direct and indirect effects of self-stigma and social capital on empowerment. Social capital and self-stigma accounted for 56% of the variability in empowerment. Higher social capital was related to lower self-stigma (r=-0.72, Psocial capital and empowerment (r=0.38, PSocial capital plays a key role in the appraisal of empowerment, both directly and through the indirect effect mediated by self-stigma. In order to improve empowerment of people with MDD, we identify strategies to foster individual social capital, and to overcome the negative consequences related to self-stigma for attainment of life goals.

Self-immolation is a fatal and devastating method of committing suicide used around the world. The chief aim of the present article is to look at the trend of indexed papers in PubMed covering different aspects of self-immolation. PubMed search engine (http://www.ncbi.nlm.nih.gov) was searched by using six keywords i.e. "self-immolation", "self-inflicted burn", "self-burning", "self-incineration", "suicidal burns" and "suicide by burning". These keywords should appear either in the title or the abstract of the articles. The time frame was set as to retrieve papers expanding from early indexing time up to end of the year 2011. Based on the search strategy 132 papers were retrieved from these total numbers; 12 (9%) were categorized as review papers; 24 (18%) as case reports and the rest 96 (73%) were original studies. It seems that the number of papers increased during the years of investigations and the highest indexed papers i.e. 14 (10.6%) belonged to the year 2011. While most journals, published only one article the highest indexed papers i.e. 35 (26.5%) belonged to Burns. There was an increasing trend in the number of self-immolation articles indexed in PubMed since 1965. Three journals i.e. Burns, Journal of Burn Care and Rehabilitation and Journal of Forensic Sciences hosted for more than 37% of all those indexed articles. However, given the increasing trend of self-immolation still more studies are needed to shed light on the diverse aspects of this appalling human behavior.

Bone marrow and skin allografts from the same donor were transplanted to rats inflicted with 8 Gy γ-radiation combined with third degree burns of 15% body surface area within 6 hr post injury. Pathological changes of hematopoietic tissues and skin allografts were studied. All injured controls died within 7 days post injury without bone marrow regeneration; 50% of treated rats survived with living skin allografts on 50th day post injury. On days 100 and 480 post operation, grafted skin still survived well on recipients with normal ultrastructure. Epidermic cells of skin allografts proliferated on day 5, developed and repaired on day 10. Histological structure of the skin returned to normal on day 30 post operation. The regeneration of bone marrow appeared on 5th day, increased markedly on day 10, and almost completed on day 15 after bone marrow transplantation. However, the regeneration of lymphocytes in cortex of spleen and lymph nodes did not appear until day 15 of BMT. The results show that bone marrow and skin allograft transplantation at early time post injury in most severe combined radiation-burn injury have tremendous beneficial effects, and the skin allograft can survive for a long time

To date, there is little research to validate empirically differences between non-suicidal self-injurious behavior (NSSI) and attempted suicide among Latina adolescents. Understanding the characteristics and contextual features of self-harmful behaviors among Latina teens is a critical public health and social justice matter given the disproportionate rates of attempted suicide and anticipated population growth of this vulnerable group. In this article, we draw on an ecodevelopmental model to focus attention on factors in the sociocultural environment that shape suicidal and non-suicidal self-injurious behaviors. Through analysis of qualitative interviews conducted with girls who used NSSI (n = 18), attempted suicide (n = 29), used NSSI and attempted suicide (n = 8,) and had no reported lifetime history of self-harm (n = 28), we describe the sociocultural factors that shaped psychosocial vulnerabilities and gave rise to decisions to use NSSI or attempt suicide. Our analysis revealed that adolescents who engaged in NSSI perceived their negative feelings as something that could be controlled through self-injurious acts, whereas powerlessness was a theme underlying the emotional states of girls who attempted suicide. When NSSI ceased to function as a mechanism for control, girls came to sudden decisions to attempt suicide. Most teens identified specific, and often multiple, situations that induced these intense affective states and shaped decisions to inflict self-harm. Two situational experiences emerged as particularly salient and promising for subsequent studies on self-harmful behaviors among Latina adolescents: transnational stress and bullying. We describe each of these and offer suggestions for future research and practice. PMID:26052816

Se trata de sistemas vetiformes y brechas hidrotermales con contenidos significativos de metales nobles. La manifestación hidrotermal El Rifle-Hato Viejo se destaca por su extensión, y está formada por brechas y vetas de cuarzo mineralizadas, vinculadas preferentemente a fracturas correspondientes al sistema de fallas NW-SE y se hospeda en rocas sedimentarias del Campaniense Tardío-Daniense. El estudio textural de los minerales del grupo de la sílice permitió el reconocimiento de varias texturas, las cuales fueron clasificadas en tres grupos: 1 texturas de crecimiento primario (calcedonia maciza, costriforme, en peine, cristales zonados, y maciza, 2 texturas de recristalización (mosaico, plumosa y llameante, y 3 texturas de reemplazo (en enrejado, paralelo y radiado. Sobre la base de este análisis se estableció la secuencia deposicional de los diferentes minerales del grupo de la sílice y se reveló la presencia de la paragénesis de alteración adularia-sericita, lo cual indicaría el desarrollo de un sistema epitermal de baja sulfuración. Estas texturas también se usaron para indicar el nivel de emplazamiento dentro del sistema epitermal; en este caso, el emplazamiento de la manifestación El Rifle-Hato Viejo se corresponde con el nivel intermedio o coloiforme-costriforme, el cual se encuentra por encima de la zona propicia para la deposición del oro, por lo que podría esperarse la presencia de contenidos más elevados en profundidad.

Patients with borderline personality disorder frequently show non-suicidal self-injury (NSSI). In these patients, NSSI often serves to reduce high levels of stress. Investigation of neurobiological mechanisms of NSSI in borderline personality disorder. In total, 21 women with borderline personality disorder and 17 healthy controls underwent a stress induction, followed by either an incision into the forearm or a sham treatment. Afterwards participants underwent resting-state functional magnetic resonance imaging while aversive tension, heart rate and heart rate variability were assessed. We found a significant influence of incision on subjective and objective stress levels with a stronger decrease of aversive tension in the borderline personality disorder group following incision than sham. Amygdala activity decreased more and functional connectivity with superior frontal gyrus normalised after incision in the borderline personality disorder group. Decreased stress levels and amygdala activity after incision support the assumption of an influence of NSSI on emotion regulation in individuals with borderline personality disorder and aids in understanding why these patients use self-inflicted pain to reduce inner tension. © The Royal College of Psychiatrists 2015.

Suicidal ideation and self-harm following K2 use.

There is emerging evidence of adverse effects associated with K2 and similar synthetic cannabinoid compounds marketed as herbal alternatives to marijuana. Few studies were identified regarding the psychiatric effects of K2, including suicidal ideation, and to our knowledge none have been written related to self-harm following use of K2. A healthy 20-year-old single Caucasian male with no previous psychiatric diagnoses or treatment was brought by police to the ED with acute agitation, confusion, suicidal ideation, and self-inflicted trauma after smoking K2. Evaluation in the ED was notable for agitation, significant abrasions, respiratory rate of 30, negative UDS, and sinus tachycardia on EKG. Once medically stabilized, he was transferred to the inpatient psychiatric unit for continued monitoring. Upon evaluation on the psychiatric unit the following day, his symptoms had completely resolved, he continued to deny any previous psychiatric history, and was discharged home. K2 and other synthetic cannabinoids have been shown to have significant medical and psychiatric adverse effects and they are still readily available for purchase. Evidence is limited regarding the psychiatric effects; however, synthetic cannabinoid products may potentially lead to suicidal ideation and self-harm behaviors amongst many other psychiatric symptoms.The long-term risks are still unclear, but some studies suggest the possibility of inducing chronic psychotic symptoms and worsening underlying psychiatric illness. Continued research is needed regarding the effects of these substances as well as an increase in public awareness of the risks.

To acknowledge the clinical significance of anxiety in depressed patients, DSM-5 included criteria for an anxious distress specifier for major depressive disorder. In the present report from the Rhode Island Methods to Improve Diagnostic Assessment and Services (MIDAS) project, we modified our previously published depression scale to include a subscale assessing the DSM-5 anxious distress specifier. From December 1995 to August 2013, 773 psychiatric outpatients with major depressive disorder completed the Clinically Useful Depression Outcome Scale (CUDOS) supplemented with questions for the DSM-5 anxious distress specifier (CUDOS-A). To examine discriminant and convergent validity, the patients were rated on clinician severity indices of depression, anxiety, and irritability. Discriminant and convergent validity was further examined in a subset of patients who completed other self-report symptom severity scales. Test-retest reliability was examined in a subset who completed the CUDOS-A twice. We compared patients who did and did not meet the DSM-5 anxious distress specifier on indices of psychosocial functioning and quality of life. The CUDOS-A subscale had high internal consistency and test-retest reliability; was more highly correlated with other self-report measures of anxiety than with measures of depression, substance use problems, eating disorders, and anger; and was more highly correlated with clinician severity ratings of anxiety than depression and irritability. CUDOS-A scores were significantly higher in depressed outpatients with a current anxiety disorder than in depressed patients without a comorbid anxiety disorder (P depressive disorder. © Copyright 2014 Physicians Postgraduate Press, Inc.

Cannabis consumption is a topical subject because of discussions about reviewing current regulations. In this context, having a more comprehensive approach to assess and monitor prevalence and consumption is highly relevant. The objective of this work was to refine current estimates about prevalence of cannabis use by combining self-report data and results derived from wastewater analysis. Self-report data was retrieved from surveys conducted in Switzerland and Europe. Wastewater samples were collected at the wastewater treatment plant of Lausanne, western Switzerland, over a 15 months period. The occurrence of 11-nor-9-carboxy-delta-9-tetrahydrocannabinol (THC-COOH), a specific metabolite of delta-9-tetrahydrocannabinol (THC), was monitored. Bayesian hierarchical models were used to estimate consumption, prevalence and number of cannabis users in the investigated area. According to survey data, 12-months prevalence in western Switzerland was estimated to 6.2% of the population aged 15 or older, with an estimated daily cannabis consumption of 8.1gday(-1)·1000inhab(-1) (at 11.2% purity). The integrative model comprising self-report and wastewater data substantially reduced the uncertainty in the estimates and suggested a last-year prevalence of 9.4%, with a daily cannabis consumption of 14.0gday(-1)·1000inhab(-1). Although in the same order of magnitude, consumption and prevalence estimates obtained with the integrative model were 78% and 52% higher compared to self-report figures, respectively. Interestingly, these figures are similar to discrepancies observed when comparing self-reported alcohol consumption and sales or tax data. The suggested integrative model allowed to account for known sources of uncertainty and provided refined estimates of cannabis prevalence in a major urban area of Switzerland.

Internalized Racism and Past-Year Major Depressive Disorder Among African-Americans: the Role of Ethnic Identity and Self-Esteem.

James, Drexler

2017-08-01

Although a large body of research focuses on discrimination as a risk for depression among African-Americans, only a dearth of research focuses on internalized racism (i.e., endorsement of negative stereotypes of one's racial group) as a risk factor. In addition, no studies have yet to examine mediators and/or moderators of the relationship between internalized racism and depression. To this end, the present study examined the mediating and moderating roles of (a) self-esteem and (b) ethnic identity on the relationship between internalized racism and past-year major depressive disorder (MDD), in a nationally representative sample of African-American adults (N = 3570) from the National Survey of American Life. Results from this study revealed an indirect association between internalized racism and past-year MDD via self-esteem, but no indirect relationship via ethnic identity. Further, results show that both self-esteem and ethnic identity individually moderate the relationship between internalized racism and past-year MDD. Collectively, these findings suggest a need to further investigate mechanisms through which internalized racism impacts mental health and factors that strengthen and/or weaken the association between internalized racism and depression.

The role of self-blaming moral emotions in major depression and their impact on social-economical decision making

Full Text Available People with major depressive disorder (MDD are more prone to experiencing moral emotions related to self-blame, such as guilt and shame. DSM-IV-TR recognises excessive or inappropriate guilt as one of the core symptoms of current MDD, whereas excessive shame is not part of the criteria for MDD. However, previous studies specifically assessing shame suggested its involvement in MDD. In the first part of this review, we will consider literature discussing the role of self-blaming moral emotions in MDD. These self-blaming moral emotions have been purported to influence people when they make social and financial decisions in cognitive studies, particularly those using neuroeconomical paradigms. Such paradigms aim to predict social behaviour in activities of daily living, by using important resource tangibles (especially money in laboratory conditions. Previous literature suggests that guilt promotes altruistic behaviour via acting out reparative tendencies, whereas shame reduces altruism by means of increasing social and interpersonal distance. In the second part of this review, we will discuss the potential influence of self-blaming moral emotions on overt behaviour in MDD, reviewing clinical and experimental studies in social and financial decision-making, in which guilt and shame were manipulated. This is not a well-established area in the depression literature, however in this opinion paper we will argue that studies of moral emotions and their impact on behavioural decision-making are of potential importance in the clinical field, by linking specific symptoms of a disorder to a behavioural outcome which may lead to stratification of clinical diagnoses in the future.

The aim of the present study was to analyze pistol and compact rifle marksmanship in close quarter combat (CQC). There is currently a controversy about what weapon is most appropriate to use in CQC, short weapon as pistols or long weapons as rifle. Forty two participants conducted two close quarter combat simulations, one with pistol and one with compact rifle. Marksmanship and time to cover the simulation were measured. Data obtained showed no significant differences between pistol and compact rifle. In addition, it was observed a tendency to obtain higher scores with compact rifle, probably be due to the higher stability provided in the shot action. Compact rifle could be an effective election in actual theaters of operation in which asymmetrical and symmetrical combat are combined and also in police interventions due to compact rifle provide higher fire power and range and obtained the same shooting performance than pistol. To the best of our knowledge this is the first study that provides empirical data to solve the discussion about the efficiency of the use of rifle and pistol in close quarter combat in military and police interventions. These results could be used to improve the military and police interventions efficiency.

Neuropsychological research can be advanced through a better understanding of relationships between executive functioning (EF) behavioral competencies and the expression of aggressive behavior. While performance-based EF measures have been widely examined, links between self-report indices and practical real-life outcomes have not yet been established. Executive Functioning Index subscale scores in this sample (N = 579) were linked to trait hostility (Buss-Perry Aggression Questionnaire), aggression in the natural environment (Lifetime Acts of Violence Assessment), and conduct disorder symptoms prior to age 15. Significant associations were found between all of the EFI subscales (Motivational Drive, Organization, Strategic Planning, Impulse Control, and Empathy), trait aggression, and conduct disturbance. Lifetime acts of aggression were predicted by all but Organization scores. Physical injuries inflicted on other(s) were 2 to 4 times more likely to occur among respondents generating low (z < -1) EFI subscale scores. While these EFI relationships were modest in size, they are pervasive in scope. These findings provide support for the potential role of perceived EF deficits in moderating lifetime aggression.

The purpose was to validate a self-efficacy (SE) instrument toward including students with disability in physical education (PE). Three scales referring to intellectual disabilities (ID), physical disabilities (PD), or visual impairments (VI) were administered to 486 physical education teacher education (PETE) majors. The sample was randomly split, and exploratory and confirmatory factor analyses (EFA and CFA, respectively) were conducted. After deleting items that did not meet inclusion criteria, EFA item loadings ranged from 0.53 to 0.91, and Cronbach's alpha reliability was high (for ID = .86, PD = .90, and VI = .92). CFA showed that the ID scale demonstrated good goodness-of-fit, whereas in the PD and in the VI scales demonstrated moderate fit. Thus, the content and construct validity of the instrument was supported.

The introduction of point-of-care devices for the management of patients on oral anticoagulation allows self-testing by the patient at home. Patients who self-test can either adjust their medication according to a pre-determined dose-INR (international normalized ratio) schedule (self-management), or they can call a clinic to be told the appropriate dose adjustment (self-monitoring). Increasing evidence suggests self-testing of oral anticoagulant therapy is equal to or better than standard monitoring. This is an updated version of the original review published in 2010. To evaluate the effects on thrombotic events, major haemorrhages, and all-cause mortality of self-monitoring or self-management of oral anticoagulant therapy compared to standard monitoring. For this review update, we re-ran the searches of the Cochrane Central Register of Controlled Trials (CENTRAL), 2015, Issue 6, the Cochrane Library, MEDLINE (Ovid, 1946 to June week 4 2015), Embase (Ovid, 1980 to 2015 week 27) on 1 July 2015. We checked bibliographies and contacted manufacturers and authors of relevant studies. We did not apply any language restrictions . Outcomes analysed were thromboembolic events, mortality, major haemorrhage, minor haemorrhage, tests in therapeutic range, frequency of testing, and feasibility of self-monitoring and self-management. Review authors independently extracted data and we used a fixed-effect model with the Mantzel-Haenzel method to calculate the pooled risk ratio (RR) and Peto's method to verify the results for uncommon outcomes. We examined heterogeneity amongst studies with the Chi(2) and I(2) statistics and used GRADE methodology to assess the quality of evidence. We identified 28 randomised trials including 8950 participants (newly incorporated in this update: 10 trials including 4227 participants). The overall quality of the evidence was generally low to moderate. Pooled estimates showed a reduction in thromboembolic events (RR 0.58, 95% CI 0.45 to 0

To know the survival rate in patients with RIFLE I and II stages on acute renal failure, treated with supportive care or continuous renal replacement therapy with PRISMA machine, at an intensive care unit. There were included patients of both sexes, aged 16 to 69 years, with acute renal failure in RIFLE I and II stages and score of scale APACHE II lower than 36 points. The sample studied was divided in two groups: a group was treated with supportive care, and the other group received continuous renal replacement therapy via PRISMA machine. We compared mortality between both groups and the association with the RIFLE stages with Pearson's chi-squared test. The average score of the scale APACHE I was 14 points, and the probability of death was 15 %. The patients with acute renal failure RIFLE I were 54.5 % and RIFLE II 45.5 %, with mortality of 30.4 % and 38.8 %, respectively. Patients in RIFLE I stage who received supportive care and continuous replacement therapy had non-statistical differences in mortality (p = 0.356). The mortality in patients with acute renal failure in RIFLE II stage treated with continuous replacement therapy was higher (p = 0.000). Because of its accessibility and lower mortality, supportive care should be the initial procedure in patients with acute renal failure in RIFLE I and II stages.

This paper has two objectives. The first is to reflect on the meaning of suicide as a sociological issue, commenting on an article by E.D. Nunes (1988) on the famous work by Durkheim. The second is to discuss the same issue within the field of public health, analyzing the contributions by the father of sociology and approaches by the fields of epidemiology, psychology, psychiatry, and psychoanalysis, highlighting the work of Brazilian authors. The paper presents information on the Brazilian epidemiological context and concludes by demonstrating that only from an analytical point of view can violent causes as a whole can be studied separately. Thus, they constantly require epistemological and epidemiological surveillance to construct indicators capable of contributing to change. This is all the more true because data on current violence need to be viewed within the context of the social crisis and changes Brazil is undergoing.

Previously depressed and never-depressed individuals identified personal characteristics (self-guides) defining their ideal, ought, and feared selves. One week later they completed the autobiographical memory test (AMT). For each participant the number of AMT cues that reflected self-guide content was determined to produce an index of AMT cue self-relevance. Individuals who had never been depressed showed no significant relationship between cue self-relevance and specificity. In contrast, in previously depressed participants there was a highly significant negative correlation between cue self-relevance and specificity--the greater the number of AMT cues that reflected self-guide content, the fewer specific memories participants recalled. It is suggested that in individuals with a history of depression, cues reflecting self-guide content are more likely to prompt a shift to processing of information within the long-term self (Conway, Singer, & Tagini, 2004), increasing the likelihood that self-related semantic information will be provided in response to cues on the autobiographical memory test.

A case–control study of 149 intentionally self-inflicted gun injury cases (including completed gun suicides) and 302 population-based controls was conducted from 2003 to 2006 in a major US city. Two focal independent variables, acute alcohol consumption and alcohol outlet availability, were measured. Conditional logistic regression was adjusted for confounding variables. Gun suicide risk to individuals in areas of high alcohol outlet availability was less than the gun suicide risk they incurred from acute alcohol consumption, especially to excess. This corroborates prior work but also uncovers new information about the relationships between acute alcohol consumption, alcohol outlets, and gun suicide. Study limitations and implications are discussed. PMID:21929327

These tactics include low-risk acts that render the current relationship more attractive by bestowing benefits on the woman, as well as cost-inflicting acts that render defection from the relationship risky or dangerous for her. Previous research has linked men's mate retention behavior with men's mate value (value as a current or potential partner using women's reports. The current research addresses limitations of that research using self-reports and cross-spousal reports from 107 married couples concerning their self-esteem and their esteem for their partner. The results indicate that the level of esteem that wives have for their husbands is positively associated with their perception of their husband's use of positive inducements and negatively associated with their husband's self-reported use of cost-inflicting mate retention behaviors (i.e., Direct Guarding, Intersexual Negative Inducements, and Intrasexual Negative Inducements. The level of self-esteem reported by men was negatively associated with their self-reported direct guarding behavior. Discussion explores the possibility that esteem—both self-esteem and esteem from one's partner—functions as an internal gauge of relative mate value.

Networked organised systems of care for patients with major trauma now exist in many countries, designed around the needs of the majority of patients (90% adults). Non-accidental injury is a significant cause of paediatric major trauma and has a different injury and age profile from accidental injury (AI). This paper compares the prehospital and inhospital phases of the patient pathway for children with suspected abuse, with those accidentally injured. The paediatric database of the national trauma registry of England and Wales, Trauma Audit and Research Network, was interrogated from April 2012 (the launch of the major trauma networks) to June 2015, comparing the patient pathway for cases of suspected child abuse (SCA) with AI. In the study population of 7825 children, 7344 (94%) were classified as AI and 481 (6%) as SCA. SCA cases were younger (median 0.4 years vs 7 years for AI), had a higher Injury Severity Score (median 16vs9 for AI), and had nearly three times higher mortality (5.7%vs2.2% for AI). Other differences included presentation to hospital evenly throughout the day and year, arrival by non-ambulance means to hospital (74%) and delayed presentation to hospital from the time of injury (median 8 hours vs 1.8 hours for AI). Despite more severe injuries, these infants were less likely to receive key interventions in a timely manner. Only 20% arrived to a designated paediatric-capable major trauma centre. Secondary transfer to specialist care, if needed, took a median of 21.6 hours from injury(vs 13.8 hours for AI). These data show that children with major trauma that is inflicted rather than accidental follow a different pathway through the trauma system. The current model of major trauma care is not a good fit for the way in which child victims of suspected abuse present to healthcare. To achieve better care, awareness of this patient profile needs to increase, and trauma networks should adjust their conventional responses. © Article author

Bipolar Disorder and the TCI: Higher Self-Transcendence in Bipolar Disorder Compared to Major Depression.

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.

Major histocompatibility complex-restricted self-recognition in responses to trinitrophenyl-Ficoll. A novel cell interaction pathway requiring self-recognition of accessory cell H-2 determinants by both T cells and B cells

In vitro primary antibody responses to limiting concentrations of trinitrophenyl (TNP)-Ficoll were shown to be T cell dependent, requiring the cooperation of T helper (TH) cells, B cells, and accessory cells. Under these conditions, TH cells derived from long-term radiation bone marrow chimeras were major histocompatibility complex (MHC) restricted in their ability to cooperate with accessory cells expressing host-type MHC determinants. The requirement for MHC-restricted self-recognition by TNP-Ficoll-reactive B cells was assessed under these T-dependent conditions. In the presence of competent TH cells, chimeric B cells were found to be MHC restricted, cooperating only with accessory cells that expressed host-type MHC products. In contrast, the soluble products of certain monoclonal T cell lines were able to directly activate B cells in response to TNP-Ficoll, bypassing any requirement for MHC-restricted self-recognition. These findings demonstrate the existence of a novel cell interaction pathway in which B cells as well as TH cells are each required to recognize self-MHC determinants on accessory cells, but are not required to recognize each other. They further demonstrate that the requirement for self-recognition by B cells may be bypassed in certain T-dependent activation pathways

Studies of human cases of self-inflicted poisoning suggest that chlorpyrifos oxon reacts not only with acetylcholinesterase and butyrylcholinesterase but also with other blood proteins. A favored candidate is albumin because in vitro and animal studies have identified tyrosine 411 of albumin as a site covalently modified by organophosphorus poisons. Our goal was to test this proposal in humans by determining whether plasma from humans poisoned by chlorpyrifos has adducts on tyrosine. Plasma samples from 5 self-poisoned humans were drawn at various time intervals after ingestion of chlorpyrifos for a total of 34 samples. All 34 samples were analyzed for plasma levels of chlorpyrifos and chlorpyrifos oxon (CPO) as a function of time post-ingestion. Eleven samples were analyzed for the presence of diethoxyphosphorylated tyrosine by mass spectrometry. Six samples yielded diethoxyphosphorylated tyrosine in pronase digests. Blood collected as late as 5 days after chlorpyrifos ingestion was positive for CPO-tyrosine, consistent with the 20-day half-life of albumin. High plasma CPO levels did not predict detectable levels of CPO-tyrosine. CPO-tyrosine was identified in pralidoxime treated patients as well as in patients not treated with pralidoxime, indicating that pralidoxime does not reverse CPO binding to tyrosine in humans. Plasma butyrylcholinesterase was a more sensitive biomarker of exposure than adducts on tyrosine. In conclusion, chlorpyrifos oxon makes a stable covalent adduct on the tyrosine residue of blood proteins in humans who ingested chlorpyrifos. PMID:23566956

Ice accumulation on insulators affected the safety of power system and may inflict serious consequences such as insulator flashover accidents and power failure. This article reported a simple method to prepare anti-icing polydimethylsiloxane superhydrophobic surface on glass by utilizing nano-particle filling method. The effect of concentration of silica nanoparticles on superhydrophobicity of the samples was investigated. The wettability, surface morphology and anti-icing property of the as-prepared superhydrophobic surface were characterized by corresponding methods. Results show that the as-prepared surface with addition amount of 7 g silica nanoparticles exhibited self-cleaning property and excellent superhydrophobicity with a contact angle of 165.7 ± 2.4° and a sliding angle of 3.8°. It was found that the ice formation was delayed for 29 min at −5 °C. Moreover, the as-prepared superhydrophobic surface showed superhydrophobicity in the pH range of 1–13 and exhibited excellent drop impact stability. The as-prepared superhydrophobic surface may be suitable for applications in cold regions owing to its flexibility, durability and anti-icing property.

Gun control laws vary greatly between states within the United States. We hypothesized that states with strict gun laws have lower mortality and resource utilization rates from pediatric firearms-related injury admissions. Kids' Inpatient Database (1997-2012) was searched for accidental (E922), self-inflicted (E955), assault (E965), legal intervention-related (E970), or undetermined circumstance (E985) firearm injuries. Patients were younger than 20 years and admitted for their injuries. Case incidence trends were examined for the study period. Propensity score-matched analyses were performed using 38 covariates to compare outcomes between states with strict or lenient gun control laws. Overall, 38,424 cases were identified, with an overall mortality of 7%. Firearm injuries were most commonly assault (64%), followed by accidental (25%), undetermined circumstance (7%), or self-inflicted (3%). A small minority involved military-grade weapons (0.2%). Most cases occurred in lenient gun control states (48%), followed by strict (47%) and neutral (6%).On 1:1 propensity score-matched analysis, in-hospital mortality by case was higher in lenient (7.5%) versus strict (6.5%) states, p = 0.013. Lenient states had a proportionally higher rate of accidental (31%) and self-inflicted injury (4%) versus strict states (17% and 1.6%, respectively), p gun control contributes not only to worse outcomes per case, but also to a more significant and detrimental impact on public health.

To describe the utility of determining plasma cystatinC concentrations in the diagnosis of acute incident kidney injury in septic shock. Prospective series of 50 patients with septic shock and plasma creatinine levels <2mg/dL hospitalized in an intensive care unit. Clinical and laboratory follow-ups were conducted, with measurements of cystatinC, urea and plasma creatinine levels from the diagnosis of septic shock to 5days later. The severity of the septic shock was assessed with the RIFLE scale. Twenty patients (40%) developed acute kidney injury: 8 (16%) were categorized as RIFLE-R, 5 (10%) as RIFLE-I and 7 (14%) as RIFLE-F. All patients categorized as RIFLE-F required extracorporeal renal clearance. Eighteen (36%) patients died, 8 (20%) of whom had developed acute kidney injury in their evolution. There was poor correlation between plasma creatinine and cystatin C levels (r=.501; P=.001), which disappeared upon reaching any degree of renal impairment on the RIFLE scale. CystatinC levels increased earlier and were better able to identify patients who would develop serious renal function impairment (RIFLE-F) than creatinine and urea levels. The initial cystatinC levels were related to mortality at 30days (OR=1.16; 95%CI: 03-.85). For patients who developed acute septic kidney injury, the plasma cystatinC levels increased before the classical markers of renal function. CystatinC also constitutes a severity biomarker that correlates with progression to RIFLE-F, the need for extrarenal clearance and, ultimately, mortality. This precocity could be useful for starting measures that prevent the progression of renal dysfunction. Copyright © 2014 Elsevier España, S.L.U. All rights reserved.

OBJECTIVES: We investigated the effect of family social and economic circumstances on intentional injury among adolescents. METHODS: We conducted a cross-sectional register study of youths aged 10 to 19 years who lived in Sweden between 1990 and 1994. We used socioeconomic status, number of parents...... in the household (1- or 2-parent home), receipt of welfare benefits, parental country of birth, and population density as exposures and compiled relative risks and population-attributable risks (PARs) for self-inflicted and interpersonal violence-related injury. RESULTS: For both genders and for both injury types......, receipt of welfare benefits showed the largest crude and net relative risks and the highest PARs. The socioeconomic status-related PAR for self-inflicted injury and the PAR related to number of parents in the household for interpersonal violence-related injury also were high. CONCLUSIONS: Intentional...

Sex work and three dimensions of self-esteem: self-worth, authenticity and self-efficacy.

Sex work is assumed to have a negative effect on self-esteem, nearly exclusively expressed as low self-worth, due to its social unacceptability and despite the diversity of persons, positions and roles within the sex industry. In this study, we asked a heterogeneous sample of 218 Canadian sex workers delivering services in various venues about how their work affected their sense of self. Using thematic analysis based on a three-dimensional conception of self-esteem - self-worth (viewing oneself in a favourable light), authenticity (being one's true self) and self-efficacy (competency) - we shed light on the relationship between involvement in sex work and self-esteem. Findings demonstrate that the relationship between sex work and self-esteem is complex: the majority of participants discussed multiple dimensions of self-esteem and often spoke of how sex work had both positive and negative effects on their sense of self. Social background factors, work location and life events and experiences also had an effect on self-esteem. Future research should take a more complex approach to understanding these issues by considering elements beyond self-worth, such as authenticity and self-efficacy, and examining how sex workers' backgrounds and individual motivations intersect with these three dimensions.

Major gene mutations in fruit tree domestication

International Nuclear Information System (INIS)

Spiegel-Roy, P.

1989-01-01

Though fruit gathering from the wild began long before domestication, fruit tree domestication started only after the establishment of grain agriculture. Banana, fig, date, grape and olive were among the first fruit trees domesticated. Most fruit trees are outbreeders, highly heterozygous and vegetatively propagated. Knowledge of genetics and economic traits controlled by major genes is limited. Ease of vegetative propagation has played a prominent part in domestication; advances in propagation technology will play a role in domestication of new crops. Changes toward domestication affected by major genes include self-fertility in peach, apricot and sour cherry, while the emergence of self-fertile almond populations is more recent and due probably to introgression from Amygdalus webbii. Self-compatibility in the sweet cherry has been attained only by pollen irradiation. A single gene controls sex in Vitis. Wild grapes are dioecious, with most domesticated cultivars hermaphrodite, and only a few females. In the papaya changes from dioecism to hermaphroditism have also occurred. Self-compatible systems have also been selected during domestication in Rubus. Changes towards parthenocarpy and seedlessness during domestication occurred in the banana, citrus, grape, fig and pineapple. In the banana, parthenocarpy is due to three complementary dominant genes; stenospermocarpy in the grape depends on two complementary recessive genes; parthenocarpy and sterility in citrus seems more complicated; however, it can be induced in genetic material of suitable background with ease by irradiation. Presence of persistent syconia in the fig is controlled by a mutant allele P dominant to wild +. Thornlessness in blackberry is recessive, while in the pineapple spineless forms are dominant. Changes affecting fruit composition owing to major genes include the disappearance of amygdalin present in bitter almonds (bitter kernel recessive to sweet), shell hardness in almond, and a recessive

Explaining the Immigrant Health Advantage: Self-selection and Protection in Health-Related Factors Among Five Major National-Origin Immigrant Groups in the United States

2017-01-01

Despite being newcomers, immigrants often exhibit better health relative to native-born populations in industrialized societies. We extend prior efforts to identify whether self-selection and/or protection explain this advantage. We examine migrant height and smoking levels just prior to immigration to test for self-selection; and we analyze smoking behavior since immigration, controlling for self-selection, to assess protection. We study individuals aged 20–49 from five major national origins: India, China, the Philippines, Mexico, and the Dominican Republic. To assess self-selection, we compare migrants, interviewed in the National Health and Interview Surveys (NHIS), with nonmigrant peers in sending nations, interviewed in the World Health Surveys. To test for protection, we contrast migrants’ changes in smoking since immigration with two counterfactuals: (1) rates that immigrants would have exhibited had they adopted the behavior of U.S.-born non-Hispanic whites in the NHIS (full —assimilation ); and (2) rates that migrants would have had if they had adopted the rates of nonmigrants in sending countries (no-migration scenario). We find statistically significant and substantial self-selection, particularly among men from both higher-skilled (Indians and Filipinos in height, Chinese in smoking) and lower-skilled (Mexican) undocumented pools. We also find significant and substantial protection in smoking among immigrant groups with stronger relative social capital (Mexicans and Dominicans). PMID:28092071

Nonconformity defines the self: the role of minority opinion status in self-concept clarity.

Science.gov (United States)

Morrison, Kimberly Rios; Wheeler, S Christian

2010-03-01

Drawing on distinctiveness and social identity theories, the present studies tested whether minority opinion holders would have a more clearly defined sense of self than majority opinion holders. In Study 1, participants who were induced to believe that they held a minority opinion on a controversial issue had higher subsequent self-concept clarity scores than did those who were induced to believe that they held a majority opinion, controlling for self-esteem. Furthermore, the relationship between minority opinion status and self-concept clarity was strongest among participants whose opinions were highly expressive of their values (Studies 2 and 3), as well as among participants who identified strongly with the group in which they were a minority (Study 3). Theoretical and practical implications of these results are discussed.

In order to minimize the dryout at the steam boiler furnace in the Thermal Power Plant Kolubara B, designed are inner rifled wall tubes. This type of tubes, with many spiral grooves cut into the bore, prevents film boiling and enables the nucleate boiling be still maintained under the condition of vapour quality being app. 1. To verify the choice of the rifled tubes instead of the cheaper, smooth tubes type being justified, analyzed is the change of the actual and critical vapour quality with the furnace height, under uniform and non-uniform heat flu through evaporator walls. Furthermore, made are hydraulic calculations for various steam boiler loads, in case of both rifled and smooth tubes types, with the purpose to check the rifles influence to pressure drop increase in comparison with the smooth tubes. Also, checked is the selection of the circulation pump. Key words: evaporator, forced circulation, rifled tubes, critical vapour quality, pressure drop

The prevalence of self-reported deliberate self harm in Irish adolescents.

LENUS (Irish Health Repository)

Morey, Carolyn

2008-01-01

BACKGROUND: Deliberate self harm is major public health problem, in particular among young people. Although several studies have addressed the prevalence of deliberate self harm among young people in the community, little is known about the extent to which deliberate self harm comes to the attention of medical services, the self harm methods used and the underlying motives. The aim of this study was to determine the prevalence of deliberate self harm in adolescents and the methods, motives and help seeking behaviour associated with this behaviour. METHODS: A cross-sectional survey using an anonymous self-report questionnaire was administered in 39 schools in the Southern area of the Health Service Executive, Ireland. Of the 4,583 adolescents aged 15-17 years who were invited to participate in the survey, 3,881 adolescents took part (response: 85%). RESULTS: A lifetime history of DSH was reported by 9.1% (n = 333) of the adolescents. DSH was more common among females (13.9%) than males (4.3%). Self cutting (66.0%) and overdose (35.2%) were the most common DSH methods. A minority of participants accessed medical services after engaging in DSH (15.3%). CONCLUSION: DSH is a significant problem in Irish adolescents and the vast majority do not come to the attention of health services. Innovative solutions for prevention and intervention are required to tackle DSH in adolescents.

Using a randomized, between-subjects experimental design, we tested hypotheses that self-critical perfectionism would moderate the effects of subtle stereotype threat (ST) for women and students in underrepresented racial/ethnic groups who are pursuing traditional degrees in science, technology, engineering, or math (STEM). A diverse sample of freshmen students (N = 294) was recruited from 2 major universities. Students were blocked by gender and race/ethnicity and randomly assigned to experience subtle ST or no ST. Participants in the subtle ST condition were primed to consider their gender, race, and ethnicity prior to completing measures of science self-efficacy. Those in the control condition completed the measures without such priming. Controlling for prior academic performance and university context, ST priming significantly interacted (a) with self-critical perfectionism to predict coping self-efficacy scores and (b) with race/ethnicity to predict end-of-semester STEM grades. A 3-way interaction of ST priming, sex, and self-critical perfectionism also predicted students' grades in courses wherein women and men were more proportionally represented. The Sex × Self-Critical Perfectionism interaction was not significant for those in the ST group but was for those in the control group. Men in the control group had higher grade-point averages (GPAs) at low levels of self-critical perfectionism than they had at higher levels of perfectionism. In contrast, women had lower GPAs when self-critical perfectionism was low, but their GPAs were higher when self-critical perfectionism was high. The findings are discussed in terms of their implications for self-efficacy and performance in the pursuit of a STEM major.

Proximal personal and environmental factors typically predict outcomes of treatment for alcohol or drug dependence (AODD), but longitudinal treatment studies have rarely examined these factors in adults with co-occurring psychiatric disorders. In adults with AODD and major depression, the aims of this study were to: (a) disaggregate person-and time-level components of network substance use and self-efficacy, (b) examine their prospective effects on posttreatment alcohol/drug use, and (c) examine whether residential environment moderated relations between these proximal factors and substance use outcomes. Veterans (N = 201) enrolled in a trial of group psychotherapy for AODD and independent MDD completed assessments every 3 months during 1 year of posttreatment follow-up. Outcome variables were percent days drinking (PDD) and using drugs (PDDRG). Proximal variables included abstinence self-efficacy and social network drinking and drug use. Self-efficacy and network substance use at the person-level prospectively predicted PDD (ps effects of social networks predicted future PDD (ps social network effects (ps network and posttreatment drinking and drug use. Both individual differences and time-specific fluctuations in proximal targets of psychosocial interventions are related to posttreatment substance use in adults with co-occurring AODD and MDD. More structured environmental settings appear to alleviate risk associated with social network substance use, and may be especially advised for those who have greater difficulty altering social networks during outpatient treatment.

There is a paucity of valid, brief instruments for the assessment of lifetime major depressive disorder (MDD) that can be used in, for example, large-scale genomics, imaging or biomarker studies on depression. We developed the LIfetime Depression Assessment Self-report (LIDAS), which assesses lifetime MDD diagnosis according to DSM criteria, and is largely based on the widely used Composite International Diagnostic Interview (CIDI). Here, we tested the feasibility and determined the sensitivity and specificity for measuring lifetime MDD with this new questionnaire, with a regular CIDI as reference. Sensitivity and specificity analyses of the online lifetime MDD questionnaire were performed in adults with (n = 177) and without (n = 87) lifetime MDD according to regular index CIDIs, selected from the Netherlands Study of Depression and Anxiety (NESDA) and Netherlands Twin Register (NTR). Feasibility was tested in an additional non-selective, population-based sample of NTR participants (n = 245). Of the 753 invited persons, 509 (68%) completed the LIDAS, of which 419 (82%) did this online. User-friendliness of the instrument was rated high. Median completion time was 6.2 min. Sensitivity and specificity for lifetime MDD were 85% [95% confidence interval (CI) 80-91%] and 80% (95% CI 72-89%), respectively. This LIDAS instrument gave a lifetime MDD prevalence of 20.8% in the population-based sample. Measuring lifetime MDD with an online instrument was feasible. Sensitivity and specificity were adequate. The instrument gave a prevalence of lifetime MDD in line with reported population prevalences. LIDAS is a promising tool for rapid determination of lifetime MDD status in large samples, such as needed for genomics studies.

Full Text Available Background. Few disaster studies have specifically examined personality and resilience in association with disaster exposure, posttraumatic stress disorder (PTSD, and major depression. Methods. 151 directly-exposed survivors of the Oklahoma City bombing randomly selected from a bombing survivor registry completed PTSD, major depression, and personality assessments using the Diagnostic Interview Schedule for DSM-IV and the Temperament and Character Inventory, respectively. Results. The most prevalent postdisaster psychiatric disorder was bombing-related PTSD (32%; major depression was second in prevalence (21%. Bombing-related PTSD was associated with the combination of low self-directedness and low cooperativeness and also with high self-transcendence and high harm avoidance in most configurations. Postdisaster major depression was significantly more prevalent among those with (56% than without (5% bombing-related PTSD (P<.001 and those with (72% than without (14% predisaster major depression (P<.001. Incident major depression was not associated with the combination of low self-directedness and low cooperativeness. Conclusions. Personality features can distinguish resilience to a specific life-threatening stressor from general indicators of well-being. Unlike bombing-related PTSD, major depression was not a robust marker of low resilience. Development and validation of measures of resilience should utilize well-defined diagnoses whenever possible, rather than relying on nonspecific measures of psychological distress.

[Automutilation with indistinct underlying disease--difficulties of care in the community].

Self-mutilation is well-known in various psychiatric diseases and represents a challenge for forensic pathologists as regards the differentiation of accidental versus self-inflicted injuries, especially when a criminal charge is likely to emerge. A case of extraordinarily severe self-inflicted injuries is presented as well as the related implications concerning clinical and ambulatory care for patients, whose underlying motivation remains unknown. A 60 year-old worker exhibited an open scull fracture and 14 abdominal wounds with protrusion of small intestine, from which a part of 160 cm length was completely removed beforehand. The patient claimed the wounds having been caused accidentally. When examined by a psychiatrist, disturbances in orientation, unrest and ill concentration were found, but no symptoms related to psychosis, depression or suicidal behaviour. Although the need for more detailed examination seemed to be clearly evident, the medical authorities did not take action. Consequently, no further psychiatric treatment was initiated. The implications of this case on the background of the literature are discussed. Georg Thieme Verlag KG Stuttgart.New York.

Previous studies have shown that self-esteem is an important predictor of subjective well-being. However, the majority of research has focused on self-esteem at the individual and the collective level, but has mostly ignored self-esteem at the relational level. According to social identity theory, individuals can maintain and enhance self-esteem through personal traits (personal self-esteem, PSE), relationships with significant others (relational self-esteem, RSE), and relationships with larg...

Change in self-esteem predicts depressive symptoms at follow-up after intensive multimodal psychotherapy for major depression.

Dinger, Ulrike; Ehrenthal, Johannes C; Nikendei, Christoph; Schauenburg, Henning

2017-09-01

Reduced self-esteem is a core symptom of depression, but few studies have investigated within-treatment change of self-esteem as a predictor of long-term outcome in depression. This study investigated change in self-esteem during 8 weeks of multimodal, psychodynamically oriented psychotherapy for 40 depressed patients and tested whether it would predict outcome 6 months after termination. Data was drawn from a randomized clinical pilot trial on day-clinic versus inpatient psychotherapy for depression. Findings supported the association between change in self-esteem and follow-up depression severity, even when controlling for within-treatment symptom change. Change in self-esteem was not related to overall symptoms and interpersonal problems at follow-up. Thus, change in self-esteem may be an important variable in preventing relapse for depression. Self-esteem is related to depressive symptoms and interpersonal problems. Improvement of self-esteem during psychotherapy correlates with improvements of symptoms and interpersonal problems. Change of self-esteem during psychotherapy predicts depressive symptoms 6 months after termination of therapy. When treating depressed patients, psychotherapists should work towards an improvement of self-esteem in order to prevent relapse. Copyright © 2017 John Wiley & Sons, Ltd.

Full Text Available Background Patients with sickle cell disease suffer from various complications during their lifetime. In order to cope with the disease, they must adapt themselves to a complex set of behaviors that promote self-management and prevent complications associated with the disease. Chronic disease self-management programs are a combination of strategies that increase self-efficacy and promote self-management behaviors. Objectives This study aimed to determine the effectiveness of self-management programs on self-efficacy in patients with sickle cell disease. Patients and Methods In this quasi-experimental study, 69 patients with sickle cell disease who were referred to the Thalassemia Clinic of Ahvaz Shafa Hospital were entered into the study through the census method. Then, the self-management program was implemented using the 5A method for 12 weeks. The Levels of pre and post intervention self-efficacy were assessed using the sickle cell self-efficacy scale (SCSES, while descriptive statistics, paired t-test and Wilcoxon test were used to analyze the data. Results Before the intervention, the majority of subjects (50.7% had moderate self-efficacy, whereas after the intervention, the majority of patients (81.2% showed high self-efficacy. The overall scores and scores of the post-intervention self-efficacy sub-groups were significantly increased (P < 0.001. Conclusions The results of this study showed that self-management interventions are effective in promoting self-efficacy in patients with sickle cell disease. Thus, the use of self-management programs is advisable to change behaviors and promote self-efficacy in such patients.

Knott, Jeff; Gilbert, Jo; Hoccom, David G.; Green, Rhys E.

2010-01-01

Lead poisoning caused by ingested spent lead shotgun pellets has long been known to be a cause of unnecessary mortality in waterfowl and has led to legislation limiting its use in many countries. Recent evidence has shown that the problem extends to terrestrial ecosystems and to fragmented rifle bullets eaten by scavengers as well as shotgun pellets. Dietary exposure of human consumers to lead from spent ammunition in game meat also poses potential risks to human health. To assess the degree of fragmentation of lead bullets used to kill wild deer, twelve deer were shot in the thorax using copper-jacketed lead-cored bullets, as part of planned deer management operations. The thoracic region of the eviscerated carcasses and the abdominal viscera of each deer were X-rayed. An average of 356 metal fragments was visible on radiographs of the carcass and 180 fragments in the viscera. The weight of fragments was estimated by reference to an X-rayed scale of fragments of known weight. The average total weight of metal fragments, likely to be mostly lead, was estimated to be 1.2 g for the carcass and 0.2 g for the viscera. The total estimated weight of fragments in the entire carcass was estimated to be 17% of the weight of the bullet. Most fragments were small in size, with those in the viscera being smaller than those in the carcass. Metal fragments in the viscera were sufficiently small that at least 80% of the metallic bullet-derived lead in the viscera would be expected to be ingested by scavenging birds, such as buzzards and eagles, which feed on them.

Kilicli, Volkan; Yan, Xiaojun; Salowitz, Nathan; Rohatgi, Pradeep K.

2018-04-01

Engineered self-healing materials inspired by natural biological organisms that can repair damage are receiving increasing interest in recent years. Most studies have been focused on self-healing polymers, concretes, and ceramics. Self-healing metallic materials pose challenges due to the high temperatures used in manufacturing and the chemistries involved. This article summarizes and evaluates the self-healing mechanisms used in metallic materials and reviews recent studies into self-healing in aluminum, zinc, and Sn-Bi alloys. Generalizations about the various classifications are drawn from the review highlighting major hurdles in the widespread practical application of metallic self-healing materials, as well as the potential directions for future studies.

Acne and facial post-inflammatory hyperpigmentation are relatively common clinical conditions among adolescents and young adults, and inflict psychosocial injuries on sufferers. To document the psychosocial and self-esteem implications of acne and facial hyperpigmentation on newly admitted undergraduates. A cross-sectional survey was conducted among 200 undergraduates. Demographics and clinical characteristics were obtained and acne was graded using the US Food and Drug Administration 5-category global system of acne classification. Participants completed the Cardiff Acne Disability Index (CADI) and the Rosenberg self-esteem scale (RSES), and data were analyzed using SPSS 20. Mean age of acne onset was 16.24 ± 3.32 years. There were 168 (84.0%) cases categorized as almost clear, 24 (12.0%) as mild acne, 4 (2.0%) as moderate acne and 4 (2.0%) as severe acne. Acne with facial hyperpigmentation, compared to acne without hyperpigmentation, was associated with significant level of anxiety in 30 participants (26.5% vs 10.3%, p =0.004) and emotional distress in 40 (35.4% vs 10.3%, p self-esteem and perception of worse disease. There was no association between gender and QoL but acne was related to a reduction of self-worth. Low self-esteem was present in 1.5%, and severe acne was associated with an occasional feeling of uselessness in the male gender. Acne with facial hyperpigmentation induces poorer QoL and self-esteem is impaired only in severe acne. Beyond the medical treatment of acne, dermatologists should routinely assess the QoL and give attention to treatment of facial post-inflammatory hyperpigmentation among people of color.

The major role of imaging in cases of suspected child abuse is to identify the physical injuries and to confirm the occurrence of abuse. In severely abused infants, the imaging findings may be the only evidence for a diagnosis of inflicted injury. Imaging may be the first clue to abuse in children seen with apparent other conditions and lead to appropriate measures to protect them from the risk of more serious injury. The radiologist must be familiar with imaging findings of inflicted injuries to fulfill these roles. (author)

2008-12-01

Full Text Available OBJECTIVE: This article describes the characteristics of violence-related injury (VRI cases presenting at emergency departments (EDs in Brazil and compares circumstances for assault-related and self-inflicted cases. METHODS: The study is cross-sectional. The data describe cases seen in September 2006 in 62 EDs, representing all 26 states and the Federal District. A total of 4 835 case records were analyzed. Basic statistical tabulations were complemented by logistic regression analysis to assess potential associations between type of violence (assault or self-harm and multiple factors. RESULTS: Males comprised 72.8% of cases while those aged 20 to 29 comprised 35.4%. Alcohol use was reported or suspected in 42.7% of cases, more commonly among males. Assault victims comprised 91.4% of cases versus self-inflicted injuries, which accounted for 8.6%. Three-fourths of the assault victims were male, while over half of the self-inflicted injury victims were female. The leading mechanism for assaults was physical force/blunt objects (46.2%, whereas poisoning was the predominant mechanism for self-inflicted injuries (71.4%. Younger females were significantly more likely to have been victims of self-inflicted injuries than younger males, while younger males were more likely to have been victims of assault; this finding is more pronounced in cases where alcohol use was reported. Self-inflicted injuries were significantly more likely to occur in residences, while assaults were more likely to occur away from home. CONCLUSION: These results can improve understanding of the scope and characteristics of VRIs in Brazil (and thus contribute to national injury prevention efforts, and help identify areas for future research.OBJETIVOS: Se describen las características de los casos de lesiones relacionadas con la violencia (LRV que se presentan en los servicios de emergencia en Brasil y se comparan las circunstancias de los casos relacionados con asaltos y los

Young, Daniel Kim-Wan; Ng, Petrus Yat-Nam; Kwok, Timothy

2017-12-01

The present research study aimed to identify and compare the clinical and non-clinical factors that predict the self-reported and proxy-reported health-related quality of life (HRQoL) of people with major neurocognitive disorder (PwND) who are living at home in a Chinese society. A total of 57 Chinese PwND-family caregiver dyads that were using the services of local senior centers were recruited through a cross-sectional survey with convenience sampling. Each PwND and caregiver rated the PwND's HRQoL independently by using the Quality of Life-Alzheimer's disease measure. Additional measures included the Rosenberg Self-Esteem Scale (RSES), Index for Managing Memory Loss, Geriatric Depression Scale, Cornell Scale for Depression in Dementia and Zarit Burden Inventory. The results of hierarchical multiple linear regression analyses showed that the PwND's self-rated HRQoL and caregiver-rated HRQoL were found to be predicted by different clinical and non-clinical variables. In particular, the self-esteem of PwND had the highest predictive power for the self-rated HRQoL, whereas the caregiver burden is the only significant predictor for the caregiver-rated HRQoL. In the present study, the self-esteem of PwND and the caregiver's burden were found to be important factors predicting self-rated HRQoL and caregiver-rated HRQoL respectively, which is probably because of the influence of traditional Chinese cultural values. Thus, it is important for non-pharmacological interventions to address these special needs to promote HRQoL for this population.

Protein tyrosine adduct in humans self-poisoned by chlorpyrifos

International Nuclear Information System (INIS)

Li, Bin; Eyer, Peter; Eddleston, Michael; Jiang, Wei; Schopfer, Lawrence M.; Lockridge, Oksana

2013-01-01

Studies of human cases of self-inflicted poisoning suggest that chlorpyrifos oxon reacts not only with acetylcholinesterase and butyrylcholinesterase but also with other blood proteins. A favored candidate is albumin because in vitro and animal studies have identified tyrosine 411 of albumin as a site covalently modified by organophosphorus poisons. Our goal was to test this proposal in humans by determining whether plasma from humans poisoned by chlorpyrifos has adducts on tyrosine. Plasma samples from 5 self-poisoned humans were drawn at various time intervals after ingestion of chlorpyrifos for a total of 34 samples. All 34 samples were analyzed for plasma levels of chlorpyrifos and chlorpyrifos oxon (CPO) as a function of time post-ingestion. Eleven samples were analyzed for the presence of diethoxyphosphorylated tyrosine by mass spectrometry. Six samples yielded diethoxyphosphorylated tyrosine in pronase digests. Blood collected as late as 5 days after chlorpyrifos ingestion was positive for CPO-tyrosine, consistent with the 20-day half-life of albumin. High plasma CPO levels did not predict detectable levels of CPO-tyrosine. CPO-tyrosine was identified in pralidoxime treated patients as well as in patients not treated with pralidoxime, indicating that pralidoxime does not reverse CPO binding to tyrosine in humans. Plasma butyrylcholinesterase was a more sensitive biomarker of exposure than adducts on tyrosine. In conclusion, chlorpyrifos oxon makes a stable covalent adduct on the tyrosine residue of blood proteins in humans who ingested chlorpyrifos. - Highlights: • Chlorpyrifos-poisoned patients have adducts on protein tyrosine. • Diethoxyphosphate-tyrosine does not lose an alkyl group. • Proteins in addition to AChE and BChE are modified by organophosphates

The Level of Vision Necessary for Competitive Performance in Rifle Shooting: Setting the Standards for Paralympic Shooting with Vision Impairment.

Allen, Peter M; Latham, Keziah; Mann, David L; Ravensbergen, Rianne H J C; Myint, Joy

2016-01-01

The aim of this study was to investigate the level of vision impairment (VI) that would reduce performance in shooting; to guide development of entry criteria to visually impaired (VI) shooting. Nineteen international-level shooters without VI took part in the study. Participants shot an air rifle, while standing, toward a regulation target placed at the end of a 10 m shooting range. Cambridge simulation glasses were used to simulate six different levels of VI. Visual acuity (VA) and contrast sensitivity (CS) were assessed along with shooting performance in each of seven conditions of simulated impairment and compared to that with habitual vision. Shooting performance was evaluated by calculating each individual's average score in every level of simulated VI and normalizing this score by expressing it as a percentage of the baseline performance achieved with habitual vision. Receiver Operating Characteristic curves were constructed to evaluate the ability of different VA and CS cut-off criteria to appropriately classify these athletes as achieving 'expected' or 'below expected' shooting results based on their performance with different levels of VA and CS. Shooting performance remained relatively unaffected by mild decreases in VA and CS, but quickly deteriorated with more moderate losses. The ability of visual function measurements to classify shooting performance was good, with 78% of performances appropriately classified using a cut-off of 0.53 logMAR and 74% appropriately classified using a cut-off of 0.83 logCS. The current inclusion criteria for VI shooting (1.0 logMAR) is conservative, maximizing the chance of including only those with an impairment that does impact performance, but potentially excluding some who do have a genuine impairment in the sport. A lower level of impairment would include more athletes who do have a genuine impairment but would potentially include those who do not actually have an impairment that impacts performance in the sport.

The present study sought to examine the interactive effects of an external locus of control and interaction in a negative peer group climate on men’s perpetration of physical aggression and infliction of injury toward their female intimate partners. Participants were 206 heterosexual males recruited from the metro-Atlanta community who completed self-report measures of external locus of control, involvement in a negative peer group climate, and physical aggression and infliction of injury against intimate partners during the past 12 months. Negative peer group climate was conceptualized as a peer group that displays behavior which may instigate aggressive norms, attitudes, and behaviors. Results indicated that men with an external locus of control were more likely to perpetrate physical aggression toward and inflict injury on their intimate partners if they reported high, but not low, involvement in a negative peer group climate. These results extend current research suggesting external locus of control as a risk factor for intimate partner aggression by highlighting the impact of negative peer groups. Implications and future intervention research are discussed. PMID:25389191

Does Self-Esteem Have an Interpersonal Imprint Beyond Self-Reports? A Meta-Analysis of Self-Esteem and Objective Interpersonal Indicators.

Cameron, Jessica J; Granger, Steve

2018-02-01

Self-esteem promises to serve as the nexus of social experiences ranging from social acceptance, interpersonal traits, interpersonal behavior, relationship quality, and relationship stability. Yet previous researchers have questioned the utility of self-esteem for understanding relational outcomes. To examine the importance of self-esteem for understanding interpersonal experiences, we conducted systematic meta-analyses on the association between trait self-esteem and five types of interpersonal indicators. To ensure our results were not due to self-esteem biases in perception, we focused our meta-analyses to 196 samples totaling 121,300 participants wherein researchers assessed interpersonal indicators via outsider reports. Results revealed that the association between self-esteem and the majority of objective interpersonal indicators was small to moderate, lowest for specific and distal outcomes, and moderated by social risk. Importantly, a subset of longitudinal studies suggests that self-esteem predicts later interpersonal experience. Our results should encourage researchers to further explore the link between self-esteem and one's interpersonal world.

Performance of the Adult ADHD Self-Report Scale-v1.1 in Adults with Major Depressive Disorder

Directory of Open Access Journals (Sweden)

Boadie W. Dunlop

2018-03-01

Full Text Available Attention deficit/hyperactivity disorder (ADHD is an under-recognized comorbid disorder among patients with mood disorders. ADHD is an independent risk factor for suicidal ideation and behavior and contributes to many aspects of impaired function in adults. Diagnosis of ADHD in Major Depressive Disorder (MDD patients is challenging due to the overlap in cognitive symptoms between the two disorders. The ADHD Self-Report Scale, version 1.1 (ASRS-v1.1 is a widely used screening instrument for ADHD in adults but its accuracy has not been evaluated previously in treatment-seeking MDD patients. We administered the ASRS-v1.1 to 55 healthy controls and 40 adults with a primary psychiatric diagnosis of MDD who were participating in clinical research studies. ADHD diagnosis was assessed via structured interview with the adult ADHD module of the Mini International Neuropsychiatric Interview Plus version 6.0.0 (MINI along with a psychiatrist’s assessment. Overall, full-syndrome ADHD was diagnosed in 12.5% of the MDD patients. MDD patients endorsed all 18 items of the ASRS-v1.1 more frequently than the healthy controls and the number of ASRS-v1.1 items endorsed correlated with levels of anxiety in the MDD patients. The ASRS-v1.1 demonstrated fair performance for identifying full syndrome DSM-IV ADHD diagnosis, with sensitivity 60%, specificity: 68.6%, positive predictive value 21.4%, negative predictive value 92.3% and total classification accuracy of 67.5%. Positive predictive value improved substantially when the ADHD criterion requiring symptom onset before age 7 was omitted. In adult MDD patients, a negative ASRS-v1.1 screen strongly suggests the absence of ADHD but positive screen results require careful evaluation to determine whether self-reported ADHD symptoms simply emerge from depression or whether comorbid ADHD is present.

Cross-sectional survey. To examine factors that may enhance and promote resilience in adults with spina bifida. Community-based disability organisations within Australia. Ninety-seven adults with a diagnosis of spina bifida (SB) completed a survey comprising of demographic questions in addition to standardised self-report measures of physical functioning (Craig Handicap Assessment and Reporting Technique), resilience (Connor-Davidson Resilience Scale, 10 item), self-esteem (Rosenberg Self-esteem Scale), self-compassion (Self-compassion Scale) and psychological distress (Depression Anxiety Stress Scales, 21 item). The majority (66%) of respondents reported moderate to high resilience. Physical disability impacted on coping, with greater CD-RISC 10 scores reported by individuals who were functionally independent in addition to those who experienced less medical co-morbidities. Significant correlations between resilience and psychological traits (self-esteem r=0.36, Pself-esteem and self-compassion. It follows that cognitive behavioural strategies with a focus on self-management may, in part, contribute to the process of resilience in this group. Further large-scale and longitudinal research will help to confirm these findings.

The NAA of the bullets and fragments from the JFK assassination not only demonstrated that U.S. President John F. Kennedy and Texas Governor John B. Connally were hit by two and only two bullets, both from Lee Harvey Oswald's rifle, but offered a considerable number of extended benefits for understanding the assassination as well. The NAA eliminated all conspiracy theories that involved additional shooters or planted bullets. The NAA proved that none of the fragments were planted, that the rifle was fired that day (not planted), and that the locations of Kennedy's head wounds and back wound were not needed in order to get the right answer for the assassination. It supported the single-bullet theory and thus helped to provide the best-documented shooting scenario to date. It knits together the core physical evidence into an airtight case against Lee Oswald. It is, thus, the key to resolving the major controversies in the JFK assassination and putting the matter to rest. (author)

2018-01-01

Dental injuries, especially of the incisors, caused by punches in violent criminal attacks could be seen in daily forensic casework involving the identification of injuries to a living body. Sometimes, when there is neither circumstantial evidence nor information about the surrounding circumstances, it is difficult to discern the cause of these injuries and the manner in which they were inflicted. As an example of clinical forensic medicine, we present the case of a 58-year-old woman whose teeth were injured when fighting with her son-in-law over household affairs with no witnesses present. The two parties had conflicting stories about the cause of the woman's injury. The woman claimed that her teeth were lost while she was being beaten by her son-in-law, and the man argued that the damage to his mother-in-law's teeth was self-inflicted when she bit his fingers. The police attending the crime called for a forensic examination. Forensic practitioners analysed the mechanism of the tooth loss using multi-slice spiral computed tomography (MSCT) and imaging reconstruction technology. Local alveolar bone (medial alveolar) fracture and a small area of alveolar bone loss were found on MSCT. Thus, forensic medical experts speculated that the woman's lower central and lateral incisors were lost as a result of a violent attack and were not self-inflicted. Finally, forensic practitioners helped police in avoiding a miscarriage of justice and wrongful conviction.

Shea, M T; Leon, A C; Mueller, T I; Solomon, D A; Warshaw, M G; Keller, M B

1996-11-01

Individuals with a history of depression are characterized by high levels of certain personality traits, particularly neuroticism, introversion, and interpersonal dependency. The authors examined the "scar hypothesis," i.e., the possibility that episodes of major depression result in lasting personality changes that persist beyond recovery from the depression. A large sample of first-degree relatives, spouses, and comparison subjects ascertained in connection with the proband sample from the National Institute of Mental Health Collaborative Program on the Psychobiology of Depression were assessed at two points in time separated by an interval of 6 years. Subjects with a prospectively observed first episode of major depression during the interval were compared with subjects remaining well in terms of change from time 1 to time 2 in self-reported personality traits. All subjects studied were well (had no mental disorders) at the time of both assessments. There was no evidence of negative change from premorbid to postmorbid assessment in any of the personality traits for subjects with a prospectively observed first episode of major depression during the interval. The results suggested a possible association of number and length of episodes with increased levels of emotional reliance and introversion, respectively. The findings suggest that self-reported personality traits do not change after a typical episode of major depression. Future studies are needed to determine whether such change occurs following more severe, chronic, or recurrent episodes of depression.

Full Text Available During war, sharp high-speed missiles have been driven inside the brain; however, in civilian practice it is rare to see such episodes. An approximately 10-cm long nail was driven inside the brain in an attempt to commit suicide by a schizophrenic patient. The case is being reported for its rarity in civilian practice and as a case of clinical interest. After investigating the patient by plain X-rays and a CT scan, he was operated by a neurosurgical team and the nail was successfully removed. In post-operative phase, patient was given medical and psychiatric care along with psychological counseling. The patient made good uneventful recovery in the post-operative phase.

In a prospective study of patients with prominent ears, the effect of reconstructive surgery on self-esteem and social interaction was examined 1 year after surgery. Of 42 patients with prominent ears aged 7 to 15 years, 21 were matched with a comparison group of orthopedic patients (leg lengthening) and a control group of schoolchildren. Psychological measures evaluated self-esteem, depression, anxiety, cognition, parents' ratings of child behavior and symptoms, and parent anxiety. Semistructured interviews with the child and parents were also conducted. The motivation to be operated on was pain, teasing, and feelings of being different. The satisfaction rate with the result of reconstructive surgery was high. The psychological measures of the prominent ears group had results close to those of the control group, although the leg lengthening group had lower self-esteem and higher depression and anxiety scores. With few exceptions, all patients had scores within the normal range on self-rating scales. Parents reported less activity at leisure time in both patient groups than in the control group. After surgery, parents reported improved behavior on the Child Behavior Checklist total problem score. Patients with minor defects had fewer self-reported psychological and behavior problems than the major defect group. Interestingly, prominent ears patients also had low activity levels. Reconstructive surgery had no adverse effect on the prominent ears patients in this interim study but rather resulted in improved well-being. It is important to investigate further the effect of reconstructive surgery on children's self-esteem and social interaction.

Possible Major Influences of Children Learning Social Studies on Academic Self Concept and Achievement

Full Text Available This study was aimed at finding the best model to explain pupil academic attainment in learning social studies. The data came from pupils learning Social Studies at grade 3 and 4 of primary schools. The structural equation model contained 2 exogenous constructs–attitudes toward school and locus of control–and 2 endogenous constructs–self-concept and academic achievement. It was confirmed that the academic self-concept and achievement related to each other and both were influenced by attitudes toward school and internal locus of control. The model was fitting differently for different grade.

Adolescent self-concept among Han, Mongolian, and Korean Chinese.

Science.gov (United States)

Sharpes, D K; Wang, X

1997-01-01

Studies of self-concept have suffered from a lack of both a solid theoretical base and a clear definition of the term. It is not clear whether self-concept is a construct from the cognitive sciences, an active part of personality or of the ego and unconscious, or a physiological process as indicated from neurological research. Nor is it clear whether the psychological construct of self is related to other concepts, such as personal identity, self-esteem, and the ego, as sometimes these refer to the whole person or a structure or element within a person. What is evident is that the majority of researchers continue to assume that self-concept, however defined in theory, is primarily governed by environmental determinants despite abundant evidence from the neurosciences of the strong influence of its genetic heritability. This study assumed a genetic hypothesis, that self-concept is developmental and that adolescent perception of personal, relational, and academic self-identity occurs uniformly across cultures and environmental circumstances. Data were collected using a validated survey instrument, translated into Chinese, from majority and minority adolescents in the People's Republic of China. High similarity was found between the majority and minority adolescents, suggesting developmental propensities in the formation of self-concept.

Espinosa, Lorelle L.

If we are to respond to the call for equity in the representation of minority men and women in science, technology, engineering, and math (STEM) disciplines, we must be concerned with those college experiences that impact students' sense of self. This study addresses the 4-year development of academic self-concept for African American and Latina(o) students graduating with STEM degrees, with an emphasis placed on gender differences. Ordinary Least Squares regression was utilized to explore predictors of academic self-concept for male and female students. Findings emphasize the paramount role of the college environment as compared to background and precollege characteristics. Significant predictors exclusive to women include having positive academic self-expectations and valuing group work in a classroom setting. Significant predictors for men include being given the opportunity to work on a professor's research project and finding satisfaction with science and math coursework.

Full Text Available The deliberate self-harm behaviour which defined as attempting to own body resulting in tisue damage without conscious desire of peolple to die, is a major public health problem worldwide. 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. The aim of this review article is to investigate the etiology and epidemiology of deliberate self-harm behaviour and relationship between psychiatric disorders.

Aims: To investigate the optimal neuroradiological investigation strategy to identify inflicted brain injury (iBI). Materials and methods: A systematic review of studies published between 1970-2008 in any language was conducted, searching 20 databases and four websites, using over 100 keywords/phrases, supplemented by hand-searching of references. All studies underwent two independent reviews (with disagreements adjudicated by a third reviewer) by trained reviewers from paediatrics, paediatric neuroradiology and related disciplines, using standardized critical appraisal tools, and strict inclusion/exclusion criteria. We included primary studies that evaluated the diagnostic yield of magnetic resonance imaging (MRI), in addition to initial computed tomography (CT), or follow-up CT or ultrasound in children with suspected iBI. Results: Of the 320 studies reviewed, 18 met the inclusion criteria, reflecting data on 367 children with iBI and 12 were published since 1998. When an MRI was conducted in addition to an abnormal early CT examination, additional information was found in 25% (95% CI: 18.3-33.16%) of children. The additional findings included further subdural haematoma, subarachnoid haemorrhage, shearing injury, ischaemia, and infarction; it also contributed to dating of injuries. Diffusion-weighted imaging (DWI) further enhanced the delineation of ischaemic changes, and assisted in prognosis. Repeat CT studies varied in timing and quality, and none were compared to the addition of an early MRI/DWI. Conclusions: In an acutely ill child, the optimal imaging strategy involves initial CT, followed by early MRI and DWI if early CT examination is abnormal, or there are ongoing clinical concerns. The role of repeat CT imaging, if early MRI is performed, is unclear, as is the place for MRI/DWI if initial CT examination is normal in an otherwise well child.

Düring, Camilla; Jessop, Donna C

2015-05-01

This study explored whether self-esteem would moderate the effectiveness of a self-affirmation manipulation at increasing openness to personally relevant health-risk information. The study employed a prospective experimental design. Participants (N = 328) completed either a self-affirmation manipulation or a control task, prior to reading information detailing the health-related consequences of taking insufficient exercise. They then completed a series of measures assessing their cognitions towards exercise and their derogation of the information. Exercise behaviour was assessed at 1-week follow-up. Self-esteem moderated the impact of self-affirmation on the majority of outcomes. For participants with low self-esteem, the self-affirmation manipulation resulted in more positive attitudes and intentions towards exercise, together with lower levels of derogation of the health-risk information. By contrast, there was no effect of the self-affirmation manipulation on outcomes for participants with high self-esteem. Findings suggest that self-affirmation manipulations might be of particular benefit for those with low self-esteem in terms of promoting openness towards health-risk information. This is promising from a health promotion perspective, as individuals with low self-esteem often represent those most in need of intervention. Statement of contribution What is already known on this subject? Self-affirmation has been shown to result in more open processing of personally relevant health-risk information. Individuals low in self-esteem tend to process such information more defensively than those high in self-esteem. What does this study add? It explores whether self-esteem moderates the impact of self-affirmation on responses to health-risk information. Findings suggest that individuals with low self-esteem benefit most from the self-affirmation manipulation. This has important applied implications, as individuals with low self-esteem may be most in need of

We examined whether problem-solving and diabetes self-management behaviors differ by depression diagnosis - major depressive disorder (MDD) and minor depressive disorder (MinDD) - in adults with Type 2 diabetes (T2DM). We screened a clinical sample of 702 adults with T2DM for depression, identified 52 positive and a sample of 51 negative individuals, and performed a structured diagnostic psychiatric interview. MDD (n=24), MinDD (n=17), and no depression (n=62) were diagnosed using Diagnostic and Statistical Manual of Mental Disorders IV (DSM-IV) Text Revised criteria. Health Problem-Solving Scale (HPSS) and Summary of Diabetes Self-Care Activities (SDSCA) questionnaires determined problem-solving and T2DM self-management skills, respectively. We compared HPSS and SDSCA scores by depression diagnosis, adjusting for age, sex, race, and diabetes duration, using linear regression. Total HPSS scores for MDD (β=-4.38; pdepression. Total SDSCA score for MDD (β=-10.1; pdepression, and was partially explained by total HPSS. MinDD and MDD individuals with T2DM have impaired problem-solving ability. MDD individuals had impaired diabetes self-management, partially explained by impaired problem-solving. Future studies should assess problem-solving therapy to treat T2DM and MinDD and integrated problem-solving with diabetes self-management for those with T2DM and MDD. Copyright © 2017 Elsevier Inc.

MOTIVATION, A BRIDGE FOR NON-ENGLISH MAJOR FRESHMEN IN THEIR TRANSITION

Institute of Scientific and Technical Information of China (English)

2000-01-01

This study intends to examine the problems that affected non-English major freshmen’s motivation and the potential factors that could influence their motivation, intrinsic or extrinsic. Self-report data were collected from 188 freshmen selected randomly in Nanchang College by using a close-ended questionnaire. Qualitative results came from interviews with 8 freshmen and 5 teachers. Findings provide evidence that some problems, which emerge with the transition from middle school to college, will influence students’ motivation. Meanwhile, intrinsic motivation can be boosted if the factors of goal, attitude, self-confidence, self-determination, learning environment, learning strategies, teaching methods are valued by teachers.

Full Text Available Foundation: the caregiver plays an important role in helping and supporting a patient with cancer, but at the same time has the emotional and work burden which this work presupposes. Objective: to determine the resilience modulating factors and the degree of burden in major caregivers of advanced cancer patients. Method: a descriptive study was developed at the Area III Policlinic Cienfuegos during the period from December 2012 to March 2013. The universe was constituted by 25 primary caregivers of patients in an advanced stage of the disease. The studied variables were: sex, age, scholarship, occupation, marital status, kinship, time to patient care, self-esteem, optimism, emotional intelligence, and burden. The techniques used were: questionnaire and test of emotional intelligence, Coopersmith self-esteem inventory, caregiver burden scale by Zarit. Results: ages between 51 and 72 years predominated 48 %, 88 % were female, 40 % had elementary school level and 48 % were married, 72 % were housewives, 44 % were patients spouses, 52 % less than a year of care giving. 60 % had an intense burden, 48 % low level of self-esteem and an intense burden. 58.3 % of caregivers with low emotional intelligence had an intense burden. Conclusion: resilience modulators, self-esteem and emotional intelligence determine the level of burden suffered by major caregivers of advanced cancer patients.

To acknowledge the clinical significance of manic features in depressed patients, DSM-5 included criteria for a mixed features specifier for major depressive disorder (MDD). In the present report from the Rhode Island Methods to Improve Diagnostic Assessment and Services (MIDAS) project we modified our previously published depression scale to include a subscale assessing the DSM-5 mixed features specifier. More than 1100 psychiatric outpatients with MDD or bipolar disorder completed the Clinically Useful Depression Outcome Scale (CUDOS) supplemented with questions for the DSM-5 mixed features specifier (CUDOS-M). To examine discriminant and convergent validity the patients were rated on clinician severity indices of depression, anxiety, agitation, and irritability. Discriminant and convergent validity was further examined in a subset of patients who completed other self-report symptom severity scales. Test-retest reliability was examined in a subset who completed the CUDOS-M twice. We compared CUDOS-M scores in patients with MDD, bipolar depression, and hypomania. The CUDOS-M subscale had high internal consistency and test-retest reliability, was more highly correlated with another self-report measure of mania than with measures of depression, anxiety, substance use problems, eating disorders, and anger, and was more highly correlated with clinician severity ratings of agitation and irritability than anxiety and depression. CUDOS-M scores were significantly higher in hypomanic patients than depressed patients, and patients with bipolar depression than patients with MDD. The study was cross-sectional, thus we did not examine whether the CUDOS-M detects emerging mixed symptoms when depressed patients are followed over time. Also, while we examined the correlation between the CUDOS-M and clinician ratings of agitation and irritability, we did not examine the association with a clinician measure of manic symptomatology such as the Young Mania Rating Scale In the

The Level of Vision Necessary for Competitive Performance in Rifle Shooting: Setting the Standards for Paralympic Shooting With Vision Impairment

Peter M Allen

2016-11-01

Full Text Available The aim of this study was to investigate the level of vision impairment that would reduce performance in shooting; to guide development of entry criteria to visually impaired (VI shooting. Nineteen international-level shooters without vision impairment took part in the study. Participants shot an air rifle, while standing, towards a regulation target placed at the end of a 10m shooting range. Cambridge simulation glasses were used to simulate six different levels of vision impairment. Visual acuity (VA and contrast sensitivity (CS were assessed along with shooting performance in each of seven conditions of simulated impairment and compared to that with habitual vision. Shooting performance was evaluated by calculating each individual’s average score in every level of simulated vision impairment and normalising this score by expressing it as a percentage of the baseline performance achieved with habitual vision. Receiver Operating Characteristic (ROC curves were constructed to evaluate the ability of different VA and CS cut-off criteria to appropriately classify these athletes as achieving ‘expected’ or ‘below expected’ shooting results based on their performance with different levels of VA and CS. Shooting performance remained relatively unaffected by mild decreases in VA and CS, but quickly deteriorated with more moderate losses. The ability of visual function measurements to classify shooting performance was good, with 78% of performances appropriately classified using a cut-off of 0.53 logMAR and 74% appropriately classified using a cut-off of 0.83 logCS. The current inclusion criteria for VI shooting (1.0 logMAR is conservative, maximising the chance of including only those with an impairment that does impact performance, but potentially excluding some who do have a genuine impairment in the sport. A lower level of impairment would include more athletes who do have a genuine impairment but would potentially include those who do not

Full Text Available Conventional pharmacotherapies and psychotherapies for major depression are associated with limited adherence to care and relatively low remission rates. Yoga may offer an alternative treatment option, but rigorous studies are few. This randomized controlled trial with blinded outcome assessors examined an 8-week hatha yoga intervention as mono-therapy for mild-to-moderate major depression.Investigators recruited 38 adults in San Francisco meeting criteria for major depression of mild-to-moderate severity, per structured psychiatric interview and scores of 14-28 on Beck Depression Inventory-II (BDI. At screening, individuals engaged in psychotherapy, antidepressant pharmacotherapy, herbal or nutraceutical mood therapies, or mind-body practices were excluded. Participants were 68% female, with mean age 43.4 years (SD = 14.8, range = 22-72, and mean BDI score 22.4 (SD = 4.5. Twenty participants were randomized to 90-minute hatha yoga practice groups twice weekly for 8 weeks. Eighteen participants were randomized to 90-minute attention control education groups twice weekly for 8 weeks. Certified yoga instructors delivered both interventions at a university clinic. Primary outcome was depression severity, measured by BDI scores every 2 weeks from baseline to 8 weeks. Secondary outcomes were self-efficacy and self-esteem, measured by scores on the General Self-Efficacy Scale (GSES and Rosenberg Self-Esteem Scale (RSES at baseline and at 8 weeks.In intent-to-treat analysis, yoga participants exhibited significantly greater 8-week decline in BDI scores than controls (p-value = 0.034. In sub-analyses of participants completing final 8-week measures, yoga participants were more likely to achieve remission, defined per final BDI score ≤ 9 (p-value = 0.018. Effect size of yoga in reducing BDI scores was large, per Cohen's d = -0.96 [95%CI, -1.81 to -0.12]. Intervention groups did not differ significantly in 8-week change scores for either the GSES or

Heterogeneity of major depressive disorder (MDD) illness course complicates clinical decision-making. Although efforts to use symptom profiles or biomarkers to develop clinically useful prognostic subtypes have had limited success, a recent report showed that machine-learning (ML) models developed from self-reports about incident episode characteristics and comorbidities among respondents with lifetime MDD in the World Health Organization World Mental Health (WMH) Surveys predicted MDD persistence, chronicity and severity with good accuracy. We report results of model validation in an independent prospective national household sample of 1056 respondents with lifetime MDD at baseline. The WMH ML models were applied to these baseline data to generate predicted outcome scores that were compared with observed scores assessed 10-12 years after baseline. ML model prediction accuracy was also compared with that of conventional logistic regression models. Area under the receiver operating characteristic curve based on ML (0.63 for high chronicity and 0.71-0.76 for the other prospective outcomes) was consistently higher than for the logistic models (0.62-0.70) despite the latter models including more predictors. A total of 34.6-38.1% of respondents with subsequent high persistence chronicity and 40.8-55.8% with the severity indicators were in the top 20% of the baseline ML-predicted risk distribution, while only 0.9% of respondents with subsequent hospitalizations and 1.5% with suicide attempts were in the lowest 20% of the ML-predicted risk distribution. These results confirm that clinically useful MDD risk-stratification models can be generated from baseline patient self-reports and that ML methods improve on conventional methods in developing such models.

Full Text Available Introduction: Psychological constructs have been found to have potential effects in the improvement of health. Self-esteem (expressed in the form of sub-constructs: Self-liking and self-competence is a construct, which makes one realize the self. This in turn will result in positive oral-health-seeking behavior and improvement in oral health status. Aim: To assess the relationship of self-liking, self-competence with self-reported oral health status in children aged 15 years, in Davangere city. Materials and Methods: A descriptive, cross-sectional survey was conducted on 220 15-year-old subjects in Davangere City. Specially designed pro forma containing Romanian self-administered questionnaire to record the self-reported oral health status and Tafarodi's SLC scale to measure self-liking/self-competence was used. Chi-square test was used for statistical analysis. Results: A majority of the participants were found to have moderate self-competence and self-liking and their self-reported oral health status was expressed as "excellent." They reported very less or no untreated decayed teeth and no extracted teeth or gingival bleeding. Conclusion: The participants with better self-competence and self-liking perceived their oral health status as good. They reported lesser incidence of oral diseases and discomfort. Self-esteem and oral health were found to be positively related.

To assess the frequency and evaluate the factors underlining self-medication with orthodox and herbal medicines among pregnant women in Ibadan, Nigeria. Setting Antenatal clinics at the major antenatal care facility in Ibadan, south-western Nigeria. A prospective cross-sectional study with a pre-tested 15-item structured questionnaire over a 12 week period among 1,650 pregnant women who attended antenatal clinics at a major antenatal care facility in Ibadan, south-western Nigeria. Data analysis was done with Chi-square, multivariate logistic regression and summary statistics. Frequency and major factors associated with self-medication in pregnancy. The response and completion rate was 96.6% (1,594) [mean age ± SD 27 ± 5.3 years]. The majority of the respondents were literate (92.6%), self-employed (61.5%) and in the third trimester (49.5%). A significant majority (63.8%) used self-medication (orthodox and herbal medicines) as their first response to perceived ill-health (P patent medicine stores (55%). Mothers-in-law and relatives (41.3%) were the most frequently cited sources of advice during self-medication. Miscarriage/bleeding (44.3%) was the most frequently cited potential adverse effect that could occur with the use of certain medicines during pregnancy. Only 32% of respondents could identify medicines that are potentially harmful in pregnancy. Poorly guided self-medication with prescription, over-the-counter and herbal medicines is pervasive and significantly associated with gestational age and occupational pattern among pregnant women in Ibadan, south-western. A majority lacked the knowledge of potential adverse outcomes associated with the use of certain medicines, and the potentially harmful medicines to avoid during pregnancy.

Spinal cord injury could be fatal in man and often results in irreversible medical conditions affecting mobility. However, anuran amphibians win over such pathological condition by the virtue of regeneration abilities. The tail of anuran tadpoles therefore allures researchers to study spinal cord injury and self- repair process. In the present study, we inflicted injury to the spinal cord by means of surgical transection of the tail and investigated the self-repair activity in the tadpoles of the Indian tree frog Polypedates maculatus. We also demonstrate for the first time by immunofluorescence localization the expression pattern of Fibroblast Growth Factor1 (FGF1) during spinal cord regeneration which has not been documented earlier in anurans. FGF1, bearer of the mitogenic and neurotrophic properties seems to be expressed by progenitor cells that facilitate regeneration. Spinal cord during tail regeneration in P. maculatus attains functional recovery within a span of 2 weeks thus enabling the organism to survive in an aquatic medium till metamorphosis. Moreover, during the course of spinal cord regeneration in the regenerating tail, melanocytes showed an interesting behaviour as these neural crest derivatives were missing near the early regenerates until their reappearance where they were positioned in close proximity with the regenerated spinal cord as in the normal tail.

To identify predictors of self-reported psychological resilience amongst medical students following major earthquakes in Canterbury in 2010 and 2011. Two hundred and fifty-three medical students from the Christchurch campus, University of Otago, were invited to participate in an electronic survey seven months following the most severe earthquake. Students completed the Connor-Davidson Resilience Scale, the Depression, Anxiety and Stress Scale, the Post-traumatic Disorder Checklist, the Work and Adjustment Scale, and the Eysenck Personality Questionnaire. Likert scales and other questions were also used to assess a range of variables including demographic and historical variables (eg, self-rated resilience prior to the earthquakes), plus the impacts of the earthquakes. The response rate was 78%. Univariate analyses identified multiple variables that were significantly associated with higher resilience. Multiple linear regression analyses produced a fitted model that was able to explain 35% of the variance in resilience scores. The best predictors of higher resilience were: retrospectively-rated personality prior to the earthquakes (higher extroversion and lower neuroticism); higher self-rated resilience prior to the earthquakes; not being exposed to the most severe earthquake; and less psychological distress following the earthquakes. Psychological resilience amongst medical students following major earthquakes was able to be predicted to a moderate extent.

Despite considerable effort, the localization of dysfunction in major depressive disorder (MDD) remains poorly understood. We present a hypothesis about its localization that builds on recent findings from primate neuropsychology. The hypothesis has four key components: a deficit in the valuation of "self" underlies the core disorder in MDD; the medial frontal cortex represents "self"; interactions between the amygdala and cortical representations update their valuation; and inefficiency in using positive feedback by orbital prefrontal cortex contributes to MDD.

While standardized diagnostic interviews using established criteria are the gold standard for assessing depression, less time consuming measures of depression and depressive symptoms are commonly used in large population health surveys. We examine the prevalence and health-related correlates of three depression measures among adults aged 18-79 years in Germany. Using cross-sectional data from the national German Health Interview and Examination Survey for Adults (DEGS1) (n=7987) and its mental health module (DEGS1-MH) (n=4483), we analysed prevalence and socio-demographic and health-related correlates of (a) major depressive disorder (MDD) established by Composite International Diagnostic Interview (CIDI) using DSM-IV-TR criteria (CIDI-MDD) in the last 12 months, (b) self-reported physician or psychotherapist diagnosed depression in the last 12 months, and (c) current depressive symptoms in the last two weeks (PHQ-9, score ≥10). Prevalence of 12-month CIDI-MDD was 4.2% in men and 9.9% in women. Prevalence of 12-month self-reported health professional-diagnosed depression was 3.8% and 8.1% and of current depressive symptoms 6.1% and 10.2% in men and women, respectively. Case-overlap between measures was only moderate (32-45%). In adjusted multivariable analyses, depression according to all three measures was associated with lower self-rated health, lower physical and social functioning, higher somatic comorbidity (except for women with 12-month CIDI-MDD), more sick leave and higher health service utilization. Persons with severe depression may be underrepresented. Associations between CIDI-MDD and correlates and overlap with other measures may be underestimated due to time lag between DEGS1 and DEGS1-MH. Prevalence and identified cases varied between these three depression measures, but all measures were consistently associated with a wide range of adverse health outcomes.

The studies of maxillofacial gunshot injuries mainly focused on evaluating the surgical interventions and physical outcomes of the procedures. In this study we aimed to analyze the pre- and post-injury psychiatric status of the patients with self-inflicted gunshot wounds to the face. This study is based on 12 subjects who attempted suicide resulting in extensive maxillofacial injuries using guns placed beneath their chins. The psychiatric evaluation was conducted by interview and using SCID-I, SCID-II, MMPI, Rosenberg Self-Esteem Scale and Suicide Probability Scale. Two subjects were healthy, 1 had bereavement, 6 had current and 5 had previous MDD (major depressive disorder), 2 had dysthymic disorder, 3 had alcohol abuse, 2 had drug abuse and 4 had antisocial personality disorder. The suicidal group was more socially introverted according to MMPI. According to Rosenberg self-esteem subscale, self esteem, the constancy of self respect and depressive mood subtests were statistically significant in the suicide group compared to the healthy controls (P suicide. The changes in the physical facial appearance after the suicide attempt caused impairment of self-esteem and the constancy of self-respect. Similar to other studies, none of our patients reattempted suicide and all tried to return to their pre-injury lifestyle and appeared to accommodate to the stigma of their physical deformities. Early diagnosis and treatment should be considered as a factor to reduce the risk for suicide attempt.

Self-curing concrete with different self-curing agents

Gopala krishna sastry, K. V. S.; manoj kumar, Putturu

2018-03-01

Concrete is recognised as a versatile construction material globally. Properties of concrete depend upon, to a greater extent, the hydration of cement and microstructure of hydrated cement. Congenial atmosphere would aid the hydration of cement and hence curing of concrete becomes essential, till a major portion of the hydration process is completed. But in areas of water inadequacy and concreting works at considerable heights, curing is problematic. Self-Curing or Internal Curing technique overcomes these problems. It supplies redundant moisture, for more than sufficient hydration of cement and diminish self-desiccation. Self-Curing agents substantially help in the conservation of water in concrete, by bringing down the evaporation during the hydration of Concrete. The present study focuses on the impact of self-curing agents such as Poly Ethylene Glycol (PEG), Poly Vinyl Alcohol (PVA) and Super Absorbent Polymer (SAP) on the concrete mix of M25 grade (reference mix). The effect of these agents on strength properties of Concrete such as compressive strength, split tensile strength and flexural strength was observed on a comparative basis which revealed that PEG 4000 was the most effective among all the agents.

The gambling industry has offered self-exclusion programs for quite a long time. Such measures are designed to limit access to gaming opportunities and provide problem gamblers with the help they need to cease or limit their gambling behaviour. However, few studies have empirically evaluated these programs. This study has three objectives: (1) to observe the participation in an improved self-exclusion program that includes an initial voluntary evaluation, phone support, and a mandatory meeting, (2) to evaluate satisfaction and usefulness of this service as perceived by self-excluders, (3) to measure the preliminary impact of this improved program. One hundred sixteen self-excluders completed a questionnaire about their satisfaction and their perception of the usefulness during the mandatory meeting. Among those participants, 39 attended an initial meeting. Comparisons between data collected at the initial meeting and data taken at the final meeting were made for those 39 participants. Data showed that gamblers chose the improved self-exclusion program 75% of the time; 25% preferred to sign a regular self-exclusion contract. Among those who chose the improved service, 40% wanted an initial voluntary evaluation and 37% of these individuals actually attended that meeting. Seventy percent of gamblers came to the mandatory meeting, which was a required condition to end their self-exclusion. The majority of participants were satisfied with the improved self-exclusion service and perceived it as useful. Major improvements were observed between the final and the initial evaluation on time and money spent, consequences of gambling, DSM-IV score, and psychological distress. The applicability of an improved self-exclusion program is discussed and, as shown in our study, the inclusion of a final mandatory meeting might not be so repulsive for self-excluders. Future research directives are also proposed.

Full Text Available Self-management has received growing attention as an effective approach for long-term condition management. Little is known about which outcomes of supported self-management are valued by patients, their families, health professionals and those who commission self-management services. This study systematically reviewed published empirical evidence in accordance with PRISMA guidelines to determine the outcomes of self-management valued by these key stakeholder groups, using three prominent exemplar conditions: colorectal cancer, diabetes and stroke.To systematically review the literature to identify which generic outcomes of self-management have been targeted and are considered important using three exemplar conditions (colorectal cancer, diabetes and stroke, which collectively have a range of features that are likely to be representative of generic self-management issues.Systematic searching of nine electronic databases was conducted in addition to hand searches of review articles. Abstracts were identified against inclusion criteria and appraised independently by two reviewers, using a critical appraisal tool. Synthesis of findings was conducted using mixed research synthesis.Over 20,536 abstracts were screened. 41 studies which met the review criteria were fully retrieved and appraised. The majority of evidence related to diabetes. Few studies directly focussed on stakeholders' views concerning desired self-management outcomes; the majority of evidence was derived from studies focusing upon the experience of self-management. The views of health care commissioners were absent from the literature. We identified that self-management outcomes embrace a range of indicators, from knowledge, skills, and bio-psychosocial markers of health through to positive social networks.Patients', families', health professionals' and commissioners' views regarding which outcomes of self-management are important have not been clearly elicited.

Full Text Available Objective: Whilst the relationship between narcissism and self-esteem has been studied for a long time, findings are still controversial. The majority of studies investigated narcissistic grandiosity, neglecting the existence of vulnerable manifestations of narcissism. Moreover, recent studies have shown that grandiosity traits are not always associated with inflated explicit self-esteem. The aim of the present study is to investigate the relationship between narcissistic traits and explicit self-esteem, distinguishing between grandiosity and vulnerability. Moreover, we consider the role of implicit self-esteem in qualifying these associations.Method: Narcissistic traits, explicit and implicit self-esteem measures were assessed among 120 university students (55.8% women, Mage = 22.55, SD = 3.03.Results: Results showed different patterns of association between narcissistic traits and explicit self-esteem, depending on phenotypic manifestations of narcissism. Narcissistic vulnerability was linked to low explicit self-evaluations regardless of one’s levels of implicit self-esteem. On the other hand, the link between narcissistic grandiosity and explicit self-esteem was qualified by levels of implicit self-views, such that grandiosity was significantly associated with inflated explicit self-evaluations only at either high or medium levels of implicit self-views.Discussion: These findings showed that the relationship between narcissistic traits and explicit self-esteem is not univocal, highlighting the importance of distinguishing between narcissistic grandiosity and narcissistic vulnerability. Finally, the study suggested that both researchers and clinicians should consider the relevant role of implicit self-views in conditioning self-esteem levels reported explicitly by individuals with grandiose narcissistic traits.

Objective: Whilst the relationship between narcissism and self-esteem has been studied for a long time, findings are still controversial. The majority of studies investigated narcissistic grandiosity (NG), neglecting the existence of vulnerable manifestations of narcissism. Moreover, recent studies have shown that grandiosity traits are not always associated with inflated explicit self-esteem. The aim of the present study is to investigate the relationship between narcissistic traits and explicit self-esteem, distinguishing between grandiosity and vulnerability. Moreover, we consider the role of implicit self-esteem in qualifying these associations. Method: Narcissistic traits, explicit and implicit self-esteem measures were assessed among 120 university students (55.8% women, Mage = 22.55, SD = 3.03). Results: Results showed different patterns of association between narcissistic traits and explicit self-esteem, depending on phenotypic manifestations of narcissism. Narcissistic vulnerability (NV) was linked to low explicit self-evaluations regardless of one’s levels of implicit self-esteem. On the other hand, the link between NG and explicit self-esteem was qualified by levels of implicit self-views, such that grandiosity was significantly associated with inflated explicit self-evaluations only at either high or medium levels of implicit self-views. Discussion: These findings showed that the relationship between narcissistic traits and explicit self-esteem is not univocal, highlighting the importance of distinguishing between NG and NV. Finally, the study suggested that both researchers and clinicians should consider the relevant role of implicit self-views in conditioning self-esteem levels reported explicitly by individuals with grandiose narcissistic traits.

Full Text Available Previous studies have shown that self-esteem is an important predictor of subjective well-being. However, the majority of research has focused on self-esteem at the individual and the collective level, but has mostly ignored self-esteem at the relational level. According to social identity theory, individuals can maintain and enhance self-esteem through personal traits (personal self-esteem, PSE, relationships with significant others (relational self-esteem, RSE, and relationships with larger groups (collective self-esteem, CSE. The current research investigated whether RSE and CSE can predict subjective well-being beyond PSE among Chinese college students.

Microbes exist in communities in the environment where they are fundamental drivers of global carbon, nutrient and metal cycles. In subsurface environments, they possess significant metabolic potential to affect these global cycles including the transformation of radionuclides. This study examined the influence of microbial communities in sediment zones undergoing biogeochemical cycling of carbon, nutrients and metals including natural attenuation of uranium. This study examined the relationship of both the microbiota (taxonomy) and their metabolic capacity (function) in driving carbon, nutrient and metal cycles including uranium reduction at the Department of Energy (DOE) Rifle Integrated Field Research Challenge (RIFRC). Objectives of this project were: 1) to apply systems-level biology through application of ‘metaomics’ approaches (collective analyses of whole microbial community DNA, RNA and protein) to the study of microbial environmental processes and their relationship to C, N and metals including the influence of microbial communities on uranium contaminant mobility in subsurface settings undergoing natural attenuation, 2) improve methodologies for data generation using metaomics (collectively metagenomics, metatranscriptomics and proteomics) technologies and analysis and interpretation of that data and 3) use the data generated from these studies towards microbial community-scale metabolic modeling. The strategy for examining these subsurface microbial communities was to generate sequence reads from microbial community DNA (metagenomics or whole genome shotgun sequencing (WGS)) and RNA (metatranscriptomcs or RNAseq) and protein information using proteomics. Results were analyzed independently and through computational modeling. Overall, the community model generated information on the microbial community structure that was observed using metaomic approaches at RIFRC sites and thus provides an important framework for continued community modeling

Delayed Presentation of Submucosal Retained Toothbrush from Self-Inflicted Injury in Patient with Schizophrenia

Directory of Open Access Journals (Sweden)

Caleb H. Creswell

2017-01-01

Full Text Available Foreign body ingestion occurs in not only children but also adults, particularly those with history of neurologic disease, alcohol use, or psychiatric disease. We present the case of a 40-year-old male with schizophrenia who presented to the emergency room with a long history of pharyngeal foreign body sensation which had recently progressed to include trismus, odynophagia, and dyspnea. Flexible laryngoscopy demonstrated fullness of the right posterior pharyngeal wall and computed tomography (CT showed a linear opaque foreign body extending from the level of the oropharynx to the thyroid ala. Further history elicited that he stabbed himself in the pharynx two years prior with a toothbrush following a command hallucination. The toothbrush was removed uneventfully via an external approach. The patient was discharged with psychiatry follow-up. This case is unusual due to the submucosal location of the foreign body and the length of retention. It demonstrates the atypical nature which patients with comorbid psychiatric illness may present following foreign body injury and the use of an external surgical approach for the removal of a retained foreign body based on CT reconstruction.

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.

When host antimicrobial defenses are severely compromised by radiation or trauma in conjunction with radiation, death from sepsis results. To evaluate therapies for sepsis in radiation casualties, we developed models of acquired and induced bacterial infections in irradiated and irradiated-wounded mice. Animals were exposed to either a mixed radiation field of equal proportions of neutrons and gamma rays (n/gamma = 1) from a TRIGA reactor or pure gamma rays from 60[Co sources. Skin wounds (15% of total body surface area) were inflicted under methoxyflurane anesthesia 1 h after irradiation. In all mice, wounding after irradiation decreased resistance to infection. Treatments with the immunomodulator synthetic trehalose dicorynomycolate (S-TDCM) before or after mixed neutron-gamma irradiation or gamma irradiation increased survival. Therapy with S-TDCM for mice irradiated with either a mixed field or gamma rays increased resistance to Klebsiella pneumoniae-induced infections. Combined therapy with S-TDCM and ceftriaxone for K. pneumoniae infections in mice exposed to a mixed radiation field or to gamma rays was more effective than single-agent therapy. In all irradiated-wounded mice, single therapy of acquired infections with an antibiotic or S-TDCM did not increase survival. Survival of irradiated-wounded mice after topical application of gentamicin sulfate cream suggested that bacteria colonizing the wound disseminated systemically in untreated irradiated mice, resulting in death from sepsis. In lethal models of acquired infections in irradiated-wounded mice, significant increases in survival were achieved when systemic treatments with S-TDCM or gentamicin were combined with topical treatments of gentamicin cream. Therapies for sepsis in all mice exposed to a mixed field were less effective than in mice exposed to gamma rays. Nonetheless, the data show a principle by which successful therapy may be provided to individuals receiving tissue trauma in conjunction with

KANSL1 variation is not a major contributing factor in self-limited focal epilepsy syndromes of childhood.

Full Text Available KANSL1 haploinsufficiency causes Koolen-de Vries syndrome (KdVS, characterized by dysmorphic features and intellectual disability; amiable personality, congenital malformations and seizures also commonly occur. The epilepsy phenotypic spectrum in KdVS is broad, but most individuals have focal seizures with some having a phenotype resembling the self-limited focal epilepsies of childhood (SFEC. We hypothesized that variants in KANSL1 contribute to pathogenesis of SFEC.We screened KANSL1 for single nucleotide variants in 90 patients with SFEC. We then screened a cohort of 208 patients with two specific SFEC syndromes, childhood epilepsy with centrotemporal spikes (CECTS and atypical childhood epilepsy with centrotemporal spikes (ACECTS for KANSL1 variants. The second cohort was also used to evaluate minor allelic variants that appeared overrepresented in the initial cohort.One variant, p.Lys104Thr, was predicted damaging and appeared overrepresented in our 90-patient cohort compared to Genome Aggregation Database (gnomAD allele frequency (0.217 to 0.116, with no homozygotes in gnomAD. However, there was no difference in p.Lys104Thr allele frequency in the follow-up CECTS/ACECTS cohort and controls. Four rare KANSL1 variants of uncertain significance were identified in the CECTS/ACECTS cohort.Our data do not support a major role for KANSL1 variants in pathogenesis of SFEC.

Non-suicidal self-injury (NSSI) is a self-destructive act that represents a considerable burden on the individual and society. Low self-esteem may be a psychological variable that is related to NSSI. However, little is known about the nature of this relationship in adulthood. This systematic review therefore aimed to provide a synthesis of the available literature on the relationship between self-esteem and NSSI. Articles were independently identified and risk of bias assessed by two reviewers searching PsycINFO, CINAHL, Medline and Web of Science databases. Inclusion criteria were: (1) a mean sample age of eighteen years or over (2) full manuscripts available in English (3) assessment of NSSI (4) assessment(s) of self-esteem. A narrative synthesis of results was undertaken. A random-effects meta-analysis of differences in self-esteem between NSSI and non-NSSI groups was also undertaken. Seventeen studies were identified and indicated a significant negative relationship between self-esteem and NSSI. The meta-analysis indicated lower self-esteem in those with experiences of NSSI versus those without, d = 0.59 - 1.17. Results suggested that although low self-esteem and NSSI are related in both clinical and non-clinical populations, there are a number of factors which also influence this relationship. The absence of longitudinal research is a major limitation of this literature. It will be important for clinicians to consider the impact of self-esteem in those seeking support for NSSI. Further research should undertake longitudinal research to better understand the self-esteem and NSSI relationship. Copyright © 2017 Elsevier B.V. All rights reserved.

Several European studies showed that low organizational justice (i.e., procedural justice and interactional justice) was associated with major depressive disorders. In these studies, however, the diagnosis of major depressive disorders may be underestimated because they identified only individuals who visited a doctor and received a diagnosis. Moreover, these studies did not consider neurotic personality traits, which can affect the occurrence of major depressive disorders. The purpose of the present study was to investigate the cross-sectional association of organizational justice with major depressive episodes in the past 12 months more precisely in Japanese employees. A total of 425 males and 708 females from five branches of a manufacturing company in Japan completed self-administered questionnaires measuring organizational justice, other job stressors (i.e., job strain, social support at work, and effort-reward imbalance), neuroticism, and demographic characteristics. A web-based self-administered version of the computerized Composite International Diagnostic Interview Version 3.0 (CIDI 3.0) was used to assess major depressive episodes. Logistic regression analyses were conducted. In the univariate analysis, low procedural justice and low interactional justice were significantly associated with major depressive episodes in the past 12 months. After adjusting for other job stressors and demographic characteristics, only the association of interactional justice remained significant. The moderating effect of neuroticism on the association of organizational justice with major depressive episodes in the past 12 months was not significant. Low interactional justice may be associated with major depressive disorders regardless or other job stressors or neurotic personality traits.

Science education must be a priority for citizens to function and be productive in a global, technological society. African Americans receive fewer science degrees in proportion to the Caucasian population. The primary purposes of this study were to determine the difference between the pretest and posttest science self-efficacy scores of African-American nonscience majors, the difference between the pretest and posttest science self-efficacy scores of African-American science majors, the relationship between science self-efficacy and course grade, the relationship between gender and science self-efficacy score, and the relationship between science self-efficacy score and course withdrawal. This study utilized a Likert survey instrument. All participants were enrolled in freshman level courses in the physical sciences at a historically black institution: a college or university. Participants completed the pretest survey within two weeks after the 12th class day of the semester. Initially, 458 participants completed the pretest survey. The posttest was administered within two weeks before the final exam. Only 245 participants completed the posttest survey. Results indicate that there is a difference in science self-efficacy of science majors and nonscience majors. There was no significant difference between the pretest and posttest science self-efficacy scores of African-American science majors and nonscience majors. There was no significant relationship between science self-efficacy and course grade, gender and science self-efficacy score, and course withdrawal and science self-efficacy score.

The current study sought to conduct a preliminary investigation of the effectiveness and feasibility of a novel, self-guided online self-compassion training for reducing psychological distress and increasing self-compassion and happiness among psychology trainees. A 6-week online self-compassion cultivation program was developed and delivered to Australian psychology trainees (n = 37), and a pre-experimental repeated-measures design was used to collect change data on self-compassion, happiness, perceived stress, emotion regulation difficulties as well as symptoms of depression, anxiety, and stress. Participants reported significant increases in self-compassion and happiness and significant decreases in depression, stress, and emotion regulation difficulties between pretest and posttest, with the majority of changes maintained at 3-month follow up.  This study provides preliminary evidence supporting the effectiveness and acceptability of online self-compassion training as a positive, integrated, and meaningful way of reducing distress and promoting self-compassion and happiness among trainee psychologists. © 2016 Wiley Periodicals, Inc.

Deciding on Science: An Analysis of Higher Education Science Student Major Choice Criteria

Science.gov (United States)

White, Stephen Wilson

The number of college students choosing to major in science, technology, engineering, and math (STEM) in the United States affects the size and quality of the American workforce (Winters, 2009). The number of graduates in these academic fields has been on the decline in the United States since the 1960s, which, according to Lips and McNeil (2009), has resulted in a diminished ability of the United States to compete in science and engineering on the world stage. The purpose of this research was to learn why students chose a STEM major and determine what decision criteria influenced this decision. According to Ajzen's (1991) theory of planned behavior (TPB), the key components of decision-making can be quantified and used as predictors of behavior. In this study the STEM majors' decision criteria were compared between different institution types (two-year, public four-year, and private four-year), and between demographic groups (age and sex). Career, grade, intrinsic, self-efficacy, and self-determination were reported as motivational factors by a majority of science majors participating in this study. Few students reported being influenced by friends and family when deciding to major in science. Science students overwhelmingly attributed the desire to solve meaningful problems as central to their decision to major in science. A majority of students surveyed credited a teacher for influencing their desire to pursue science as a college major. This new information about the motivational construct of the studied group of science majors can be applied to the previously stated problem of not enough STEM majors in the American higher education system to provide workers required to fill the demand of a globally STEM-competitive United States (National Academy of Sciences, National Academy of Engineering, & Institute of Medicine, 2010).

Science or liberal arts? Cultural capital and college major choice in China.

Science.gov (United States)

Hu, Anning; Wu, Xiaogang

2017-12-19

Previous studies on major East Asian societies such as Japan and Korea generally fail to find a strong effect of cultural capital in educational inequality, partly due to the characteristic extreme focus on standardized test and curriculum. This study shifts attention to the horizontal stratification of education by investigating the association between family background, cultural capital, and college major choice in contemporary China. Based on analysis of data from the Beijing College Students Panel Survey (BCSPS), we found that, on average, cultural capital significantly mediates the relationship between family background and college major preference. Those with greater endowment of cultural capital are more likely to come from socio-economically advantaged families, and, at the same time, demonstrate a stronger propensity to major in liberal arts fields rather than science, technology, engineering and mathematics (STEM) fields. Further analyses reveal that the association between cultural capital and academic field choice comes into being by way of performance in the Chinese test in the national college entrance examination and of the non-cognitive dispositions, such as self-efficacy and self-esteem. Our findings better our understanding of formation of the horizontal stratification of higher education. © London School of Economics and Political Science 2017.

The History and Timing of Depression Onset as Predictors of Young-Adult Self-Esteem

Science.gov (United States)

Lloyd, Donald A.; Ueno, Koji

2010-01-01

Depression often emerges early in the lifecourse and is consistently shown to be associated with poor self-esteem. The three main objectives of the current study are to (1) evaluate the association between a history major depression and self-esteem in young adulthood; (2) assess the relationship between timing of depression onset and young adult self-esteem; and (3) help rule out the alternative interpretation that the relationship between major depression and self-esteem is due to state dependence bias stemming from recent depressive symptoms and stressful life events. To address these objectives we use data from a two-wave panel study based on a community sample of young adults in Miami-Dade County, Florida (n = 1,197). Results indicated a history of major depression during sensitive periods of social development is associated with negative changes in self-esteem over a two-year period during the transition to young adulthood. Among those with a history of depression, earlier onset was more problematic than later onset for young adult self-esteem, although the difference disappeared once the level of self-esteem two years prior was controlled. The linkages between the history and timing of depression onset with self-esteem were observed net of recent depressive symptoms and stressful life events, and thus robust to an alternative interpretation of state dependence. The findings support the argument that major depression, especially if it develops earlier during child-adolescent development, has negative consequences for one’s self-esteem. PMID:21860585

General versus gender-specific attributes of the psychology major.

McCray, Jason A; King, Alan R; Bailly, Matthew D

2005-04-01

In the present study, the authors extended the search for general and gender-specific factors associated with the selection of psychology as a college major by using the Family Environment Scale (FES; R. H. Moos & B. S. Moos, 1994) and Coolidge Axis II Inventory (CATI; F. L. Coolidge & M. M. Merwin, 1992). The findings were restricted to one general (Schizoid) and one gender-specific (Self-Defeating) set of personality traits that seemed to be associated with the selection of a college major. The intuitive role of many presumed gender-specific factors (e.g., women are more open to discussing personal problems with others) may prove difficult to establish empirically.

To study the disagreement between self-reported suicidal ideation (SR-SI) and clinician-ascertained suicidal ideation (CA-SI) and its correlation with depression and anxiety severity in patients with major depressive disorder (MDD) or bipolar disorder (BPD). Routine clinical outpatients were diagnosed with the MINI-STEP-BD version. SR-SI was extracted from the 16 Item Quick Inventory of Depression Symptomatology Self-Report (QIDS-SR-16) item 12. CA-SI was extracted from a modified Suicide Assessment module of the MINI. Depression and anxiety severity were measured with the QIDS-SR-16 and Zung Self-Rating Anxiety Scale. Chi-square, Fisher exact, and bivariate linear logistic regression were used for analyses. Of 103 patients with MDD, 5.8% endorsed any CA-SI and 22.4% endorsed any SR-SI. Of the 147 patients with BPD, 18.4% endorsed any CA-SI and 35.9% endorsed any SR-SI. The agreement between any SR-SI and any CA-SI was 83.5% for MDD and 83.1% for BPD, with weighted Kappa of 0.30 and 0.43, respectively. QIDS-SR-16 score, female gender, and ≥4 year college education were associated with increased risk for disagreement, 15.44 ± 4.52 versus 18.39 ± 3.49 points (p = 0.0026), 67% versus 46% (p = 0.0783), and 61% versus 29% (p = 0.0096). The disagreement was positively correlated to depression severity in both MDD and BPD with a correlation coefficient R(2) = 0.40 and 0.79, respectively, but was only positively correlated to anxiety severity in BPD with a R(2) = 0.46. Self-reported questionnaire was more likely to reveal higher frequency and severity of SI than clinician-ascertained, suggesting that a combination of self-reported and clinical-ascertained suicidal risk assessment with measuring depression and anxiety severity may be necessary for suicide prevention.

All the patients filled out the Persian version of the Temperament and Character Inventory (TCI. Data were analyzed using SPSS version 17, Chi square, T test and Multiple Regression. The level of significance was set at 5%.The present study demonstrates a link between depression and lower persistence (p≤0.001, self-directedness (p≤0.001 and cooperativeness (p≤0.001 scores. A negative correlation between age and Harm Avoidance (p≤0.001 was observed in both groups.Lower scores of persistence (P, self-directedness (SD and cooperativeness (CO were observed in patients with depression more than controls even in the remission phase which could indicate a relationship between these traits and depression.

Megan E. Stitz

2013-04-01

Full Text Available The relationship between experiencing major stress events (MSEs and changes in appearance (CAs was studied in a sample of 128 participants. All participants completed the Major Stress Event and Changes in Appearance Inventory. Results indicated a significant correlation between experiencing MSEs and considered or actual CAs (r = .50 p < .01. Scores on the Changes in Appearance Inventory were significantly higher in groups with moderate to high scores on the Major Stress Event scale. This relationship between MSEs and CAs was affected by age but not gender. These results suggest that stressful life events may prompt body image dissatisfaction and underlie motivations for changes in body appearance to promote self-image. Successive or dramatic appearance changes may be an important signal of stressful experiences.

This study was designed to determine the proportion of general out patients who practice self medication, the drugs employed and the reasons for resorting to self medication. This study was conducted between June and December, 2007 at the General Outpatient Clinic of the Federal Medical Centre, Owo, Ondo State, Nigeria. Two hundred consenting respondents were selected by simple random sampling and interviewed with the aid of semi structured questionnaire by the authors with three assistants. Information regarding their bio-data, history of self medication, drugs used and the reasons for resorting to self medication were obtained. Majority of the respondents (85%) admitted to self medication while the remaining proportion (15%) did not practice it. Drugs utilized could be single, usually analgesics (26.5%) and anti-malaria (15.9%) or in combinations, usually antimalaria-analgesics (22.4%), antimalariaanalgesic- antibiotic (15.3%) and antibiotic-analgesic (10.0%). The reasons cited by respondents for self medication were their perception of their complaints been minor enough to be amenable to self medication (54.7%) and financial constraint (22.4%). Majority of the respondents practiced self medication using an array of drugs like analgesics, anti-malaria and antibiotics used either singly or in combination. The main reasons identified for self medication were that the ailments were minor and financial constraint.

Self Service Technologies: A Cause of Unemployment

Directory of Open Access Journals (Sweden)

Otekhile Cathy-Austin

2016-06-01

Full Text Available The self-service technologies (SSTs are fast changing the conventional way of transacting business by business organisations. The rapid innovation of self-service technologies and its adoption and usages in all facets of human systems is acclaimed to be fast rendering low skilled workers jobless. The major sectors of the economy in advanced economies have reached their peaks and can no longer provide new employment due to an increase in the productivity growth rate as a result of technology advances. These SSTs have in no small measure brought about an increase in productivity growth rate, cost reduction and anincrease in the speed of service delivery to customers. This paper examines if self-service technologies truly are the cause of persistent unemployment through a study of the long term metamorphosis of the major economic sectors in advanced economies. This study revealed that the SSTs presents both risks and opportunities.

The purpose of this study was to evaluate the effects of age at onset of the first major depressive episode on the clinical features of individuals with major depressive disorder (MDD) in a large cohort of Korean depressed patients. We recruited 419 MDD patients of age over 18 years from the Clinical Research Center for Depression study in South Korea. At the start of the study, the onset age of the first major depressive episode was self-reported by the subjects. The subjects were divided into four age-at-onset subgroups: childhood and adolescent onset (ages depressive episodes (F=3.475, p=0.016) and higher scores on the brief psychiatric rating scale (F=3.254, p=0.022), its negative symptom subscale (F=6.082, pdepressive episode is a promising clinical indicator for the clinical presentation, course, and outcome of MDD.

Do Self-Incentives and Self-Rewards Change Behavior? A Systematic Review and Meta-Analysis.

Science.gov (United States)

Brown, Emma M; Smith, Debbie M; Epton, Tracy; Armitage, Christopher J

2018-01-01

Encouraging people to self-incentivize (i.e., to reward themselves in the future if they are successful in changing their behavior) or self-reward (i.e., prompt people to reward themselves once they have successfully changed their behavior) are techniques that are frequently embedded within complex behavior change interventions. However, it is not clear whether self-incentives or self-rewards per se are effective at bringing about behavior change. Nine databases were searched alongside manual searching of systematic reviews and online research registers. One thousand four hundred papers were retrieved, spanning a range of behaviors, though the majority of included papers were in the domain of "health psychology". Ten studies matched the inclusion criteria for self-incentive but no studies were retrieved for self-reward. The present systematic review and meta-analysis is therefore the first to evaluate the unique effect of self-incentives on behavior change. Effect sizes were retrieved from 7 of the 10 studies. Analysis of the 7 studies produced a very small pooled effect size for self-incentives (k = 7, N = 1,161), which was statistically significant, d + = 0.17, CI [0.06, 0.29]. The weak effect size and dearth of studies raises the question of why self-incentivizing is such a widely employed component of behavior change interventions. The present research opens up a new field of inquiry to establish: (a) whether or not self-incentivizing and self-rewarding are effective behavior change techniques, (b) whether self-incentives and self-rewards need to be deployed alongside other behavior change techniques, and, (c) when and for whom self-incentives and self-rewards could support effective behavior change.

Landini, Alberto; Cocchi, Alessandro; Bardazzi, Riccardo; Sardelli, Mauro; Puntri, Stefano

2013-06-01

The market of the sights for the 5.56 mm assault rifles is dominated by mainly three types of systems: TWS (Thermal Weapon Sight), the Pocket Scope with Weapon Mount and the Clip-on. The latter are designed primarily for special forces and snipers use, while the TWS design is triggered mainly by the DRI (Detection, Recognition, Identification) requirements. The Pocket Scope design is focused on respecting the SWaP (Size, Weight and Power dissipation) requirements. Compared to the TWS systems, for the last two years there was a significant technological growth of the Pocket Scope/Weapon Mount solutions, concentrated on the compression of the overall dimensions. The trend for the assault rifles is the use of small size/light weight (SWaP) IR sights, suitable mainly for close combat operations but also for extraordinary use as pocket scopes - handheld or helmet mounted. The latest developments made by Selex ES S.p.A. are responding precisely to the above-mentioned trend, through a miniaturized Day/Night sight embedding state-of-the art sensors and using standard protocols (USB 2.0, Bluetooth 4.0) for interfacing with PDAs, Wearable computers, etc., while maintaining the "shoot around the corner" capability. Indeed, inside the miniaturized Day/Night sight architecture, a wireless link using Bluetooth technology has been implemented to transmit the video streaming of the rifle sight to an helmet mounted display. The video of the rifle sight is transmitted only to the eye-piece of the soldier shouldering the rifle.

Effect of the self-pumped limiter concept on the tritium fuel cycle

International Nuclear Information System (INIS)

Finn, P.A.; Sze, D.K.; Hassanein, A.

1988-01-01

The self-pumped limiter concept was the impurity control system for the reactor in the Tokamak Power Systems Study (TPSS). The use of a self-pumped limiter had a major impact on the design of the tritium systems of the TPSS fusion reactor. The self-pumped limiter functions by depositing the helium ash under a layer of metal (vanadium). The majority of the hydrogen species are recycled at the plasma edge; a small fraction permeates to the blanket/coolant which was lithium in TPSS. Use of the self-pumped limiter results in the elimination of the plasma processing system. Thus, the blanket tritium processing system becomes the major tritium system. The main advantages achieved for the tritium systems with a self-pumped limiter are a reduction in the capital cost of tritium processing equipment as well as a reduction in building space, a reduced tritium inventory for processing and for reserve storage, an increase in the inherent safety of the fusion plant and an improvement in economics for a fusion world economy

Gender equity in STEM: The role of dual enrollment science courses in selecting a college major

Science.gov (United States)

Persons, Christopher Andrew

A disproportionately low number of women, despite rigorous high school preparation and evidenced interest in STEM through voluntary participation in additional coursework, declare a STEM-related college major. The result of this drop in participation in STEM-related college majors is a job market flooded with men and the support of an incorrect stereotype: STEM is for men. This research seeks to assess the effects, if any, that Dual Enrollment (DE) science courses have on students' self-identified intent to declare a STEM-related college major as well as the respective perceptions of both male and female students. Self-Determination Theory and Gender Equity Framework were used respectively as the theoretical frames. High school students from six schools in two district participated in an online survey and focus groups in this mixed methods study. The results of the research identified the role the DE course played in their choice of college major, possible interventions to correct the underrepresentation, and societal causes for the stereotype.

Self-esteem is a major "predictor" of satisfaction with life. This longitudinal study examined mean and individual changes in self-esteem, and how self-esteem is affected by race and body mass. Girls were recruited at ages 9 and 10 years, and followed to age 22 years. The Harter Self-Perception Profile was administered every other year, analyzing scores from the Global Self-Worth Scale, by age or developmental phase: ages 9-12 (I), 13-16 (II), and 17-22 (III). Regression modeling included main effects and interactions between age/phase, race, and body mass index (BMI). Self-worth was greater in black than white women, and greater with lower BMI in both races. In the model with age ("traditional model") (with race and BMI), significant variables included BMI (inverse relationship) and the interactions between age and race, race and BMI, and the triple interaction between age, race, and BMI. In the model with phase ("transitional model") (with race and BMI), BMI, and the interactions between BMI and race, and race and phase, were significant. For example, self-worth was generally lower in Phase II (middle adolescence) for white women. Self-esteem tracked significantly (correlation 0.22, p self-esteem in adolescent girls, race and BMI are important predictors of self-esteem. Self-esteem is consistent across the phases of adolescence, and comparable with other personality traits. As noted by others, lower levels of self-esteem may increase the vulnerability of adolescents to risky behaviors.

Student Self-Assessment in HOCS Science Examinations: Is There a Problem?

Science.gov (United States)

Zoller, Uri; Ben-Chaim, David

1998-06-01

A specially-designed self-assessment questionnaire (SAQHOCS), containing higher-order cognitive skills (HOCS)-type questions, was administered to 71 biology majors, enrolled in a four-year college program. The gap between students' self-assessment marking, and that of their HOCS-biased teachers (the authors), is accounted for by the prevailing LOCS-orientation and the "testing culture"—a total separation between testing and learning—in contemporary science teaching. The majority of the students in the study evaluated themselves as capable of self-assessment, and felt reasonably confident in doing so. They were quite reserved as far as the applicability of the self-assessment method to nonalgorithmic ("correct/incorrect") questions is concerned. The results of this study suggest that the potential for student self-assessment within college science teaching and learning exists. However, still a great purposed effort in HOCS-oriented teaching and learning is required in order for the student self-assessment practice to become a routine integral component of HOCS science examinations.

Although chronic heart failure (CHF) is often complicated by comorbid depression and poor self-care, little is known about their specific association in patients with CHF. To investigate self-care behavior among patients with CHF with different degrees of depression severity. A total of 287 patients with documented CHF, New York Heart Association functional class II to IV, completed the European Heart Failure Self-Care Behavior Scale. The Structured Clinical Interview for DSM (SCID) IV served as the criterion standard for the presence of a depressive disorder. Analyses of covariance and linear regression analyses revealed that patients with CHF with minor depression reported significantly lower levels of self-care than patients with major depression (P = .003) and nondepressed patients (P = .014). In addition to minor depression, age (P < or = .001), multimorbidity (P = .01), left ventricular ejection fraction (P = .001), and family status (P = .01) were determinants of self-care. Our results demonstrate that patients with CHF with minor depression and not major depression are at higher risk for poor self-care and its resulting consequences, such as symptom deterioration and frequent hospitalization.

The influence, legitimacy and application of Evidence Based Medicine (EBM) in the world is growing as a tool that integrates, the best available evidence to decision making in patient care. Our goal was to identify the relationship between self-perception about the relevance of Evidence Based Medicine (EBM) and the degree of basic knowledge of this discipline in a group of physicians. A survey was carried out in a third level public hospital in Mexico City. Self-perception was measured by means of a structured scale, and the degree of knowledge through parameter or "rubrics" methodology. A total of 320 questionnaires were given to 55 medical students (17 %); 45 pre-graduate medical interns (14 %); 118 medical residents (37 %) and 102 appointed physicians of different specialties (32 %). Self-perception of EBM: The majority of those surveyed (n = 274, 86 %) declared that they were very or moderately familiar with EBM. The great majority (n = 270, 84 %) believe that EBM is very important in clinical practice and 197 physicians (61 %) said that they implement it always or usually. The global index of self-perception was 75 %. Knowledge of EBM: Definition of EBM; Seven of those surveyed (2 %) included 3 of the 4 characteristics of the definition, 82 (26 %) mentioned only two characteristics of the definition, 152 (48 %) mentioned only one characteristic and 79 (25 %) did not include any characteristic of EBM. Phases of the EBM process: The majority of those surveyed (n = 218, 68 %) did not include the steps that characterize the practice of EBM, of which 79 participants (25 %) mentioned elements not related to it. The global index of knowledge was 19 %. The majority of the surveyed physicians have a high self-perception of the relevance of EBM. In spite of this, the majority of them did not know the characteristics that define the EBM and phases of the process for its practice. A major discrepancy was found between self-perception and the

Acute kidney injury (AKI) is an important complication of idiopathic nephrotic syndrome (INS) and is associated with adverse outcomes, especially the development of chronic kidney disease (CKD). We aimed to determine the clinical profile of children with INS who developed AKI and its short-term outcome. This prospective study was conducted from March 2014 to October 2015. A total of 119 children of INS (age: 2-18 years) fulfilling the pediatric RIFLE criteria for the diagnosis of AKI were enrolled and followed up for 3 months to determine the outcome. Factors predisposing to CKD were studied. The mean age at presentation was 8.8 ± 3.59 years and males were 74 (62.2%). At presentation, 61 (51.3%) children were in Risk category, 43 (36.1%) in Injury category, and 15 (12.6%) in Failure category. Most of them (41.2%) had steroid-resistant nephrotic syndrome (SRNS) and focal segmental glomerulosclerosis (FSGS) on histopathology (33.6%). Infections were the major predisposing factor for AKI in 67 (56.3%) cases. Drug toxicity was the next common, found in 52 (43.7%) children. A total of 65 (54.6%) children recovered from AKI, while 54 (45.4%) did not. CKD developed in 49 (41.2%) non-recovered cases and 5 (4.2%) children succumbed to acute illness. SRNS, cyclosporine use, FSGS on histology, and drug toxicity were significant factors associated with the development of CKD. AKI associated with INS is a reversible condition in most cases but it can progress to CKD, especially among those who have SRNS, FSGS, and drug toxicity.

Understanding Negative Self-Evaluations in Borderline Personality Disorder-a Review of Self-Related Cognitions, Emotions, and Motives.

Winter, Dorina; Bohus, Martin; Lis, Stefanie

2017-03-01

Self-conscious emotions, such as guilt, shame, or self-disgust, as well as self-related motives, such as self-enhancement or self-verification, influence how people perceive, evaluate, memorize, and respond to self-related information. They not only influence peoples' concepts of themselves but may also affect their behavior in social environments. In the current review, we describe alterations of self-related processing in borderline personality disorder (BPD). We chose BPD as an example of a mental disorder of which impairments in self-functioning and identity constitute a major feature. Since terminology used in clinical research on self-referential processing is diverse and often confusing, we start with reviewing some of the main concepts in this area of research using a conceptual framework provided from social psychology. Most studies on self-referential processing in BPD focused on descriptions of self-esteem and revealed a negative self-concept, particularly expressed by explicitly reported low self-esteem. Moreover, self-esteem is unstable in BPD and likely reactive to self-relevant cues. BPD patients are prone to negative emotions with respect to themselves, such as self-disgust and shame. First data point to altered self-related motives, too. In conclusion, although explicit self-esteem is widely studied as a global and trait-like feature of BPD, there is a strong lack of studies that take the complexity of the construct self-esteem into account. Further studies on alterations in self-related processes are required to deepen our understanding of impairments of the self-concept in BPD and enable the improvement of psychosocial therapeutic approaches.

Skin conductance response to the pain of others predicts later costly helping.

Directory of Open Access Journals (Sweden)

Grit Hein

Full Text Available People show autonomic responses when they empathize with the suffering of another person. However, little is known about how these autonomic changes are related to prosocial behavior. We measured skin conductance responses (SCRs and affect ratings in participants while either receiving painful stimulation themselves, or observing pain being inflicted on another person. In a later session, they could prevent the infliction of pain in the other by choosing to endure pain themselves. Our results show that the strength of empathy-related vicarious skin conductance responses predicts later costly helping. Moreover, the higher the match between SCR magnitudes during the observation of pain in others and SCR magnitude during self pain, the more likely a person is to engage in costly helping. We conclude that prosocial motivation is fostered by the strength of the vicarious autonomic response as well as its match with first-hand autonomic experience.

Murata, Chiyoe; Kondo, Takaaki; Tamakoshi, Koji; Yatsuya, Hiroshi; Toyoshima, Hideaki

2006-01-01

The purpose of this study was to investigate factors related to self-rated health and to mortality among 2490 community-living elderly. Respondents were followed for 7.3 years for all-cause mortality. To compare the relative impact of each variable, we employed logistic regression analysis for self-rated health and Cox hazard analysis for mortality. Cox analysis stratified by gender, follow-up periods, age group, and functional status was also employed. Series of analysis found that factors associated with self-rated health and with mortality were not identical. Psychological factors such as perceived isolation at home or 'ikigai (one aspect of psychological well-being)' were associated with self-rated health only. Age, functional status, and social relations were associated both with self-rated health and mortality after controlling for possible confounders. Illnesses and functional status accounted for 35-40% of variances in the fair/poor self-rated health. Differences by gender and functional status were observed in the factors related to self-rated health. Overall, self-rated health effect on mortality was stronger for people with no functional impairment, for shorter follow-up period, and for young-old age group. Although, illnesses and functional status were major determinants of self-rated health, economical, psychological, and social factors were also related to self-rated health.

2005-01-01

Abstract Purpose To determine the self-concepts of chiropractic students as science students and if any personal variable affect their self-concepts. Participants Students in their first trimester and eighth trimester at the Los Angeles College of Chiropractic during the 1993 academic year (n=158). Methods Peterson-Yaakobi Q-Sort, National Assessment of Educational Progress, two-tailed T-test, one way analysis of variance and Spearman-rho correlation. Results The majority of students have positive self- concepts as science students and although there was a difference between the 2 trimesters, it was not significant. As a group they generally had less exposure to science compared to undergraduates from a selected science program. Variables of socio-economic status, undergraduate major, and highest completed level of education did not statistically affect their self-concept. Conclusion Chiropractic students had the self-concept that enables them to subscribe to the philosophical foundations of science and better engage in basic sciences and, later, science-based clinical research. Knowledge of this self- concept can be used in the development of a more rigorous basic science curricula and clinical research programs at chiropractic colleges with the ultimate goal of providing a more firm scientifically based foundation for the profession.

Favazza, A R; Rosenthal, R J

1993-02-01

Pathological self-mutilation--the deliberate alteration or destruction of body tissue without conscious suicidal intent--was examined both as a symptom of mental disorders and as a distinct syndrome. Data from more than 250 articles and books were reviewed, as well as data obtained by the authors from their extensive clinical experience in treating self-mutilating patients. The diverse behaviors that constitute pathological self-mutilation can be categorized into three basic types: major--infrequent acts that result in significant tissue damage, usually associated with psychoses and acute intoxications; stereotypic--fixed, rhythmic behavior seemingly devoid of symbolism, commonly associated with mental retardation; and superficial or moderate--behavior such as skin cutting, burning, and scratching associated with a variety of mental disorders. The authors propose that a syndrome of repetitive superficial or moderate self-mutilation should be regarded as an axis I impulse disorder. In most cases, the syndrome coexists with character pathology.

Full Text Available OBJETIVE: Recent literature has highlighted the role of psychotherapy in the treatment of major depressive disorder. Combined therapies comprising both psychotherapy and pharmacotherapy have presented the best results. Although several kinds of psychotherapies have been studied in the treatment of depressive disorders, there remains a lack of data on psychodramatic psychotherapy in the treatment of major depressive disorder. The objective of this study was to evaluate the impact of psychodramatic psychotherapy (in a sample of major depressive disorder patients. METHOD: This is an open, naturalistic, controlled, non-randomized study. Twenty major depressive disorder patients (according to the DSM-IV criteria, under pharmacological treatment for depression, with Hamilton Depression Scale total scores between 7 and 20 (mild to moderate depression, were divided into two groups. Patients in the psychotherapeutic group took part in 4 individual and 24 structured psychodramatic group sessions, whilst subjects in the control group did not participate in this psychodramatic psychotherapy. Both groups were evaluated with the Social Adjustment Scale - Self Report and the Hamilton Depression Scale. RESULTS: Psychotherapeutic group patients showed a significant improvement according to the Social Adjustment Scale - Self Report and the Hamilton Depression Scale scores at endpoint, compared to those of the control group. CONCLUSIONS: Results suggest that individual and group psychodramatic psychotherapy, associated to pharmacological treatment, provides good clinical benefits in the treatment of major depressive disorder.

The school short form of the Coopersmith Self-Esteem Inventory is a widely used measure of children's global self-esteem. Unlike the full-length scale, however, it has been generally understood that the short form does not allow differentiation between the major individual sources of self-esteem. The present study has examined the internal…

Uzuntiryaki, Esen; Çapa Aydın, Yeşim

2009-08-01

This study described the process of developing and validating the College Chemistry Self-Efficacy Scale (CCSS) that can be used to assess college students’ beliefs in their ability to perform essential tasks in chemistry. In the first phase, data collected from 363 college students provided evidence for the validity and reliability of the new scale. Three dimensions emerged: self-efficacy for cognitive skills, self-efficacy for psychomotor skills, and self-efficacy for everyday applications. In the second phase, data collected from an independent sample of 353 college students confirmed the factorial structure of the 21-item CCSS. The Cronbach alpha coefficients ranged from 0.82 to 0.92. In addition, each dimension of the CCSS had moderate and significant correlations with student chemistry achievement and differentiated between major and non-major students. Followed by the additional validation studies, the CCSS will serve as a valuable tool for both instructors and researchers in science education to assess college students’ chemistry self-efficacy beliefs.

One influential view is that vulnerability to major depressive disorder (MDD) is associated with a proneness to experience negative emotions in general. In contrast, blame attribution theories emphasise the importance of blaming oneself rather than others for negative events. Our previous exploratory study provided support for the attributional hypothesis that patients with remitted MDD show no overall bias towards negative emotions, but a selective bias towards emotions entailing self-blame relative to emotions that entail blaming others. More specifically, we found a decreased proneness for contempt/disgust towards others relative to oneself (i.e. self-contempt bias). Here, we report a definitive test of the competing general negative versus specific attributional bias theories of MDD. We compared a medication-free remitted MDD (n=101) and a control group (n=70) with no family or personal history of MDD on a previously validated experimental test of moral emotions. The task measures proneness to specific emotions associated with different types of self-blame (guilt, shame, self-contempt/disgust, self-indignation/anger) and blame of others (other-indignation/anger, other-contempt/disgust) whilst controlling for the intensity of unpleasantness. We confirmed the hypothesis that patients with MDD exhibit an increased self-contempt bias with a reduction in contempt/disgust towards others. Furthermore, they also showed a decreased proneness for indignation/anger towards others. This corroborates the prediction that vulnerability to MDD is associated with an imbalance of specific self- and other-blaming emotions rather than a general increase in negative emotions. This has important implications for neurocognitive models and calls for novel focussed interventions to rebalance blame in MDD. Crown Copyright © 2015. Published by Elsevier Masson SAS.

Full Text Available Suicide notes are usually written with pen or marker on a paper, notebook, wall or mirror. However, suicide notes written on one’s own body is very rare, and suicide note engraved with some metallic object on the body has not been reported yet. In the present suicidal death, the victim while carving some letters on the left arm with a razor had an incidental cut on right thumb. This incidental cut on the palm may be referred as “cutaneous cut sign” which gives a clue that the carving on the body with a sharp object was written by the victim himself. It also provides an additional importance of examination of palm for the presence of supportive evidences.

The association of major depressive episode and personality traits in patients with fibromyalgia

2011-01-01

Full Text Available INTRODUCTION: Personality traits have been associated with primary depression. However, it is not known whether this association takes place in the case of depression comorbid with fibromyalgia. OBJECTIVE: The authors investigated the association between a current major depressive episode and temperament traits (e.g., harm avoidance. METHOD: A sample of 69 adult female patients with fibromyalgia was assessed with the Temperament and Character Inventory. Psychiatric diagnoses were assessed with the Mini-International Neuropsychiatric Interview severity of depressive symptomatology with the Beck Depression Inventory, and anxiety symptomatology with the IDATE-state and pain intensity with a visual analog scale. RESULTS: A current major depressive episode was diagnosed in 28 (40.5% of the patients. They presented higher levels of harm avoidance and lower levels of cooperativeness and self-directedness compared with non-depressed patients, which is consistent with the Temperament and Character Inventory profile of subjects with primary depression. However, in contrast to previous results in primary depression, no association between a major depressive episode and self-transcendence was found. CONCLUSIONS: The results highlight specific features of depression in fibromyalgia subjects and may prove important for enhancing the diagnosis and prognosis of depression in fibromyalgia patients.

Experiencing a major natural disaster is a stressful event that challenges survival and sense of self. Adolescents are undergoing rapid developmental change in self-concept, and their sense of self is particularly susceptible to such stressful events. Although many studies have investigated adolescent self-concept, few have examined self-concept in relation to experiencing a natural disaster. Following the Great Wenchuan Earthquake in Sichuan Province, China, in 2008, this study aimed to (a) describe disaster experiences; (b) describe social support, coping, and self-support; and (c) identify disaster experiences, social support, and coping factors associated with self-concept of adolescent survivors 3 months after the earthquake. This was a large-scale cross-sectional study. A total of 1,976 adolescents living where the earthquake caused the most severe damage took part. The Tennessee Self-Concept Scale; Coping Styles Scale; and Internality, Powerful Others, and Chance Scales were used to assess self-concept, coping strategy, and locus of control, respectively. Sociodemographic characteristics, earthquake experiences, and social support were also obtained by self-report. Three months after the disaster, adolescent self-concept was generally positive. Locus of control centered on powerful others was the strongest predictor of total self-concept. The negative coping strategy, "abreacting," was a positive predictor of negative self-concept (self-criticism). Close attention to adolescents who use negative coping strategies and who tend to lack a sense of control is needed after major disaster events. Studies that examine long-term relationships between earthquake and other major disaster experiences and self-concept of adolescent survivors are needed.

Evolutionary relationships among self-incompatibility RNases

Igic, Boris; Kohn, Joshua R.

2001-01-01

T2-type RNases are responsible for self-pollen recognition and rejection in three distantly related families of flowering plants—the Solanaceae, Scrophulariaceae, and Rosaceae. We used phylogenetic analyses of 67 T2-type RNases together with information on intron number and position to determine whether the use of RNases for self-incompatibility in these families is homologous or convergent. All methods of phylogenetic reconstruction as well as patterns of variation in intron structure find that all self-incompatibility RNases along with non-S genes from only two taxa form a monophyletic clade. Several lines of evidence suggest that the best interpretation of this pattern is homology of self-incompatibility RNases from the Scrophulariaceae, Solanaceae, and Rosaceae. Because the most recent common ancestor of these three families is the ancestor of ≈75% of dicot families, our results indicate that RNase-based self-incompatibility was the ancestral state in the majority of dicots.

Herwig, Uwe; Kaffenberger, Tina; Schell, Caroline; Jäncke, Lutz; Brühl, Annette B

2012-05-24

Self-referential cognitions are important for self-monitoring and self-regulation. Previous studies have addressed the neural correlates of self-referential processes in response to or related to external stimuli. We here investigated brain activity associated with a short, exclusively mental process of self-reflection in the absence of external stimuli or behavioural requirements. Healthy subjects reflected either on themselves, a personally known or an unknown person during functional magnetic resonance imaging (fMRI). The reflection period was initialized by a cue and followed by photographs of the respective persons (perception of pictures of oneself or the other person). Self-reflection, compared with reflecting on the other persons and to a major part also compared with perceiving photographs of one-self, was associated with more prominent dorsomedial and lateral prefrontal, insular, anterior and posterior cingulate activations. Whereas some of these areas showed activity in the "other"-conditions as well, self-selective characteristics were revealed in right dorsolateral prefrontal and posterior cingulate cortex for self-reflection; in anterior cingulate cortex for self-perception and in the left inferior parietal lobe for self-reflection and -perception. Altogether, cingulate, medial and lateral prefrontal, insular and inferior parietal regions show relevance for self-related cognitions, with in part self-specificity in terms of comparison with the known-, unknown- and perception-conditions. Notably, the results are obtained here without behavioural response supporting the reliability of this methodological approach of applying a solely mental intervention. We suggest considering the reported structures when investigating psychopathologically affected self-related processing.

Colliding clusters and dark matter self-interactions

DEFF Research Database (Denmark)

Kahlhoefer, Felix; Schmidt-Hoberg, Kai; Frandsen, Mads Toudal

2014-01-01

When a dark matter halo moves through a background of dark matter particles, self-interactions can lead to both deceleration and evaporation of the halo and thus shift its centroid relative to the collisionless stars and galaxies. We study the magnitude and time evolution of this shift for two...... classes of dark matter self-interactions, viz. frequent self-interactions with low momentum transfer (e.g. due to long-range interactions) and rare self-interactions with high momentum transfer (e.g. contact interactions), and find important differences between the two cases. We find that neither effect...... can be strong enough to completely separate the dark matter halo from the galaxies, if we impose conservative bounds on the self-interaction cross-section. The majority of both populations remain bound to the same gravitational potential and the peaks of their distributions are therefore always...

The neural correlates of visual self-recognition.

Science.gov (United States)

Devue, Christel; Brédart, Serge

2011-03-01

This paper presents a review of studies that were aimed at determining which brain regions are recruited during visual self-recognition, with a particular focus on self-face recognition. A complex bilateral network, involving frontal, parietal and occipital areas, appears to be associated with self-face recognition, with a particularly high implication of the right hemisphere. Results indicate that it remains difficult to determine which specific cognitive operation is reflected by each recruited brain area, in part due to the variability of used control stimuli and experimental tasks. A synthesis of the interpretations provided by previous studies is presented. The relevance of using self-recognition as an indicator of self-awareness is discussed. We argue that a major aim of future research in the field should be to identify more clearly the cognitive operations induced by the perception of the self-face, and search for dissociations between neural correlates and cognitive components.

Benish-Weisman, Maya; Daniel, Ella; Schiefer, David; Möllering, Anna; Knafo-Noam, Ariel

2015-10-01

The research examined the relationship between multiple social identifications and self-esteem. Early adolescents (M = 11.4, SD = .95) and mid-adolescents (M = 15.9, SD = 1.18) from Germany and Israel (n = 2337) were studied. Respondents described their social identification as students, family members, and as members of the majority national group and reported self-esteem. A longitudinal, cross-sectional and cross-cultural design revealed, as predicted, multiple social identifications related positively to self-esteem concurrently; they also related positively to self-esteem longitudinally over the course of a year. Moreover, multiple social identifications were found to be antecedent to self-esteem, not vice versa. Finally, multiple social identifications were found to decrease over time. The article discusses the contribution of multiple social identifications to self-esteem at different ages and in various contexts.

In 24 April 2013, Rana Plaza - a high-rise building in Bangladesh where garments were being made for the Western markets collapsed. In this study, we report on the surviving workers' physical strength, self-efficacy, and disability level one year after the disaster. This cross-sectional study took place at the Centre for the Rehabilitation of the Paralysed (CRP) which provided care for more than 600 victims. For this study, upper extremity strength among the survivors was assessed by dynamometer hand grip (HG) and lower extremity strength by five time sit to stand test (FTSST). The WHODAS tool measured level of disability and General Self-Efficacy questionnaire measured self-efficacy. Post-traumatic stress disorder (PTSD) prevalence was determined by the PCL-scale. The study recruited 181 injured workers. The mean disability score among them was 49.8 (SD 17.5) and mean self-efficacy score was 24.9 (SD 6.9). In multivariate models, after adjusting for age, gender, education, injury profile, employment, marital status and job category, self-efficacy was found to be higher among those who scored above median HG test score [β= -2.32 (95% CI: -4.63, -0.01)] and FTSST performance score [β= -2.69 (95% CI: -4.93, -0.46)]. The disability level was found to be significantly associated with PTSD score [β = 0.84 (95% CI: 0.62, 1.06)] and self-efficacy score [β= -0.45 (95% CI: -0.78, -0.13)]. There is an immense need to develop and deliver effective post-injury recovery, rehabilitation and return-to-work programs for injured workers in resource poor countries. Implications for Rehabilitation The study findings suggest that one year after the factory disaster in Bangladesh, the injured workers are suffering from a high degree of disability, low physical performance and reporting low self-efficacy.

2015-12-01

Today's science classrooms are addressing the need for non-scientists to become scientifically literate. A key aspect includes the recognition of science as a process for discovery. This process relies upon interdisciplinary collaboration. We designed a semester-long collaborative exercise that allows science majors taking a general microbiology course and non-science majors taking an introductory environmental science course to experience collaboration in science by combining their differing skill sets to identify microorganisms enriched in Winogradsky columns. These columns are self-sufficient ecosystems that allow researchers to study bacterial populations under specified environmental conditions. Non-science majors identified phototrophic bacteria enriched in the column by analyzing the signature chlorophyll absorption spectra whereas science majors used 16S rRNA gene sequencing to identify the general bacterial diversity. Students then compiled their results and worked together to generate lab reports with their final conclusions identifying the microorganisms present in their column. Surveys and lab reports were utilized to evaluate the learning objectives of this activity. In pre-surveys, nonmajors' and majors' answers diverged considerably, with majors providing responses that were more accurate and more in line with the working definition of collaboration. In post-surveys, the answers between majors and nonmajors converged, with both groups providing accurate responses. Lab reports showed that students were able to successfully identify bacteria present in the columns. These results demonstrate that laboratory exercises designed to group students across disciplinary lines can be an important tool in promoting science education across disciplines.

No Girls Allowed: Women in Male-Dominated Majors Experience Increased Gender Harassment and Bias.

Dresden, Brooke E; Dresden, Alexander Y; Ridge, Robert D; Yamawaki, Niwako

2018-06-01

The prevalence of gender harassment in male-dominated workforces has been well established, but little is known regarding the experiences of women in male-dominated majors within academia. The current study examines the experiences and gender-related biases of 146 male and female students in male-dominated (MD) and gender-equivalent (GE) majors. This study hypothesizes that men from MD majors, as opposed to GE majors, will exhibit more explicit and implicit bias regarding women in positions of power and authority, resulting in a higher prevalence of gender harassment towards women in MD majors. Results showed that there was no significant difference in self-reported explicit bias against women in positions of power and authority between men from MD and GE majors, but there was significantly more implicit bias among men from MD majors as opposed to GE majors. Additionally, women from MD majors experienced significantly more gender harassment than women from GE majors. Implications of these findings and suggestions to assist those working in education to combat these biases and instances of harassment are discussed.

Full Text Available Introduction: Behavioral addictions such as gambling, sun-tanning, shopping, internet use, work, exercise, or even love and sex are frequent, and share many characteristics and common neurobiological and genetic underpinnings with substance addictions (i.e., tolerance, withdrawal, and relapse. Recent literature suggests that both non-suicidal self-injury (NSSI and suicidal behavior (SB can also be conceptualized as addictions. The major aim of this mini review is to review the literature and explore the neurobiological and psychological mechanisms underlying the addiction to self-harming behaviors.Method: This is a narrative review. The authors performed literature searches on PubMed and Google for suicidal behavior, self-harming, addiction, and major repeaters. Given the scarce literature on the topic, a subset of the most closely related studies was selected. The authors also focused on three empirical studies testing the hypothesis that major repeaters (individuals with ≥5 lifetime suicide attempts represent a distinctive suicidal phenotype, and are the individuals at risk of developing an addiction to SB. Results: The authors reviewed the concept of behavioral addictions and major repeaters, current empirical evidence testing concerning whether or not NSSI and SB can be understood as addictions, and the putative mechanisms underlying them.Conclusion: Our review suggests that both NSSI and SB can be conceptualized as addictions. This is relevant because if some individual’s self-harming behaviors are better conceptualized as an addiction, treatment approaches could be tailored to this addiction.

Recent literature suggests that both non-suicidal self-injury (NSSI) and suicidal behavior (SB) can also be conceptualized as addictions. The major aim of this mini review is to review the literature and explore the neurobiological and psychological mechanisms underlying the addiction to self-harming behaviors. This is a narrative review. The authors performed literature searches in PubMed and Google for suicidal behavior, self-harming, addiction, and "major repeaters." Given the scarce literature on the topic, a subset of the most closely related studies was selected. The authors also focused on three empirical studies testing the hypothesis that major repeaters (individuals with ≥5 lifetime suicide attempts) represent a distinctive suicidal phenotype and are the individuals at risk of developing an addiction to SB. The authors reviewed the concept of behavioral addictions and major repeaters, current empirical evidence testing concerning whether or not NSSI and SB can be understood as "addictions," and the putative mechanisms underlying them. Our review suggests that both NSSI and SB can be conceptualized as addictions. This is relevant because if some individual's self-harming behaviors are better conceptualized as an addiction, treatment approaches could be tailored to this addiction.

The dynamic interplay between perceived true self-knowledge and decision satisfaction.

Science.gov (United States)

Schlegel, Rebecca J; Hicks, Joshua A; Davis, William E; Hirsch, Kelly A; Smith, Christina M

2013-03-01

The present research used multiple methods to examine the hypothesis that perceived true self-knowledge and decision satisfaction are inextricably linked together by a widely held "true-self-as-guide" lay theory of decision making. Consistent with this proposition, Study 1 found that participants rated using the true self as a guide as more important for achieving personal satisfaction than a variety of other potential decision-making strategies. After establishing the prevalence of this lay theory, the remaining studies then focused on examining the proposed consequent relationship between perceived true self-knowledge and decision satisfaction. Consistent with hypotheses, 2 cross-sectional correlational studies (Studies 2 and 3) found a positive relationship between perceived true self-knowledge and decision satisfaction for different types of major decisions. Study 4 used daily diary methods to demonstrate that fluctuations in perceived true self-knowledge reliably covary with fluctuations in decision satisfaction. Finally, 2 studies directly examined the causal direction of this relationship through experimental manipulation and revealed that the relationship is truly bidirectional. More specifically, Study 5 showed that manipulating perceived knowledge of the true self (but not other self-concepts) directly affects decision satisfaction. Study 6 showed that this effect also works in reverse by manipulating feelings of decision satisfaction, which directly affected perceived knowledge of the true self (but not other self-concepts). Taken together, these studies suggest that people believe the true self should be used as a guide when making major life decisions and that this belief has observable consequences for the self and decision making.

Fu-I, Lee; Wang, Yuan Pang

2008-06-01

To compare clinical characteristics of major depressive disorder symptoms between children and adolescents. The subjects were 58 patients of a Child and Adolescent Affective Disorder Clinic consecutively admitted during a six-month period. Children aged 5-9 years old and adolescents from 10-17 years old currently meeting DSM-IV criteria diagnosis of major depressive disorder were chosen. Current MDD diagnosis and depressive psychopathology were assessed by a clinical interview and the Diagnostic Interview for Children and Adolescents-DSM-IV version. The Children's Depression Rating Scale-Revised Version and the Children Global Assessment Scale rated the severity and global functioning of major depressive disorder. The most common depressive symptoms were: anhedonia (72.4%), depressed mood (72.4%), decreased concentration (62.1%), and irritability (58.6%). The intensity of depressive episodes of this sample ranged from mild to moderate. Fifty percent reported thoughts of death, and 29.3% presented a variety of psychotic symptoms. When compared with children, adolescents reported a significantly more depressed mood (p = 0.043), lower self-esteem (p = 0.002), and had more difficulty concentrating (p = 0.020). Female adolescents had lower self-esteem (p = 0.003), and male adolescents showed more decreased concentration (p = 0.016). This study suggests that age and gender differences might influence the clinical presentation of major depressive disorder in children and adolescents. Further studies with larger samples are needed.

Some mechanistic requirements for major transitions.

Major transitions in nature and human society are accompanied by a substantial change towards higher complexity in the core of the evolving system. New features are established, novel hierarchies emerge, new regulatory mechanisms are required and so on. An obvious way to achieve higher complexity is integration of autonomous elements into new organized systems whereby the previously independent units give up their autonomy at least in part. In this contribution, we reconsider the more than 40 years old hypercycle model and analyse it by the tools of stochastic chemical kinetics. An open system is implemented in the form of a flow reactor. The formation of new dynamically organized units through integration of competitors is identified with transcritical bifurcations. In the stochastic model, the fully organized state is quasi-stationary whereas the unorganized state corresponds to a population with natural selection. The stability of the organized state depends strongly on the number of individual subspecies, n, that have to be integrated: two and three classes of individuals, [Formula: see text] and [Formula: see text], readily form quasi-stationary states. The four-membered deterministic dynamical system, [Formula: see text], is stable but in the stochastic approach self-enhancing fluctuations drive it into extinction. In systems with five and more classes of individuals, [Formula: see text], the state of cooperation is unstable and the solutions of the deterministic ODEs exhibit large amplitude oscillations. In the stochastic system self-enhancing fluctuations lead to extinction as observed with [Formula: see text] Interestingly, cooperative systems in nature are commonly two-membered as shown by numerous examples of binary symbiosis. A few cases of symbiosis of three partners, called three-way symbiosis, have been found and were analysed within the past decade. Four-way symbiosis is rather rare but was reported to occur in fungus-growing ants. The model

Discovering the Self in Islam: Self-Striving, Self-Regard, and Self-Neglect

This study explored some self domains and reviewed them through Islamic perspective, more particularly self-knowledge and faith. It provided an extensive literature on particular concepts of self-striving, self-regard, and self-neglect. To briefly point out, the self has many origins, however deeply noted as such heart, spirit, and psyche in Islam. From these, this study looked at the two known self domains: self-striving, and self-regard. Apart from these concepts, researchers differently ch...

Introduction Gunshot injuries of the head and neck from the AK-47 rifle (a common assault rifle, submachine gun type) are a significant contributor to morbidity and mortality among civilians in Sub-Saharan Africa. They may cause significant damage to the closely arranged structures in this region, and the bullet’s trajectory can be very difficult to determine. We present an unusual case of gunshot injury with an atypical bullet entry wound, profound injury to the face, lodgment in the right c...

Full Text Available Suicide by self-burning remains a common method of suicide amongst women in Iraq and some neighboring countries. This study aimed to describe the problem of self-burning in Basra province and investigate the associated factors. A prospective study was undertaken between October 2016 and May 2017 in Al-Fayhaa Burn Center. Data were collected from all patients admitted to the center for a self-inflicted burn. Sociodemographic information and cause of suicide were obtained using an interviewer-administered questionnaire, and clinical data were transcribed from hospital records. There were 62 cases (females 74%, males 26% of self-burning during the 6 months data collection accounting for 22% of all burn admission. The age ranged from 9-56 years (mean 25.3, SD 10.8 year. The vast majority had no or only basic education (92%, 55% were married, 60% were from outside Basra city and 53% considered themselves from a poor socioeconomic background. The incident mostly occurred at home (84% while the person was alone (91% using kerosene as the burning material (82%. The total burn surface area ranged from 20-100% with a median of 80% (IQR 60-95. The median hospital stay was 5 days (IQR 1-12 days. In-hospital mortality rate was 72.6%. Suicide by self-burning seems not to be uncommon in Basra and require more attention from public health and social services. More research is required to provide a better estimation of the problem and in-depth understanding of the factors that contribute to the problem.

In the process of developing a professional medical expertise, goals can become a psychological impetus and act as a source of retaining an individual's persistency. Therefore, the goals of medical students should be considered when designing a curriculum for health professions. The purpose of this study was to examine relative effects of goal categories on the value of learning and intention to change one's major. Data were obtained from the Korea Education Longitudinal Study, which included 1938 representative Korean college freshmen majoring in medicine, engineering, natural science and humanities. They answered a survey questionnaire about goal categories (i.e., social concern, affiliation, self-growth, leisure, wealth, and fame), the value of learning, and intention to change one's major. For medical students, social concern goals were positively related to the value of learning and negatively related to the intention to change one's major. Social concern goals decreased the intention to change one's major directly, and also indirectly through increased value of learning. Providing context for enhancing medical students' social concern goals is necessary in a medical training curriculum, not only for the students' professional development but also for improving society.

Colliding clusters and dark matter self-interactions

When a dark matter halo moves through a background of dark matter particles, self-interactions can lead to both deceleration and evaporation of the halo and thus shift its centroid relative to the collisionless stars and galaxies. We study the magnitude and time evolution of this shift for two classes of dark matter self-interactions, viz. frequent self-interactions with small momentum transfer (e.g. due to long-range interactions) and rare self-interactions with large momentum transfer (e.g. contact interactions), and find important differences between the two cases. We find that neither effect can be strong enough to completely separate the dark matter halo from the galaxies, if we impose conservative bounds on the self-interaction cross-section. The majority of both populations remain bound to the same gravitational potential and the peaks of their distributions are therefore always coincident. Consequently any apparent separation is mainly due to particles which are leaving the gravitational potential, so...
