    Samson, Kristine

    , experience and consumption are all strategic design tools applied by planners and architects. Whereas urban design in former modernist planning served merely functional or political means, urban design has increasingly become an aesthetical mediator of ideologies embedded in the urban field of life forces...... capitalism not only changes urban life and its means of production, it specifically influences the way the city is designed and how it unfolds as events (Anderson & Harrison 2010) and affective, emotional production (Pile 2009). Through examples of urban design and events in the Carlsberg City in Copenhagen...... and The High Line in Chelsea, New York, the paper sets out to define and question these affective modes of production. Whether these productions are socio-material practices consisting of ludic designs (Stevens 2007), temporary architecture or art installations or evental practices consisting of...

    Salovaara-Moring, Inka

    Recently, in human geography there has been a considerable attention paid to retheorising maps; less as a product and more as practice. This refers to the notion that rather than reading maps as fixed representations, digital mapping is by nature a dynamic, performative, and participatory practice....... In particular, mapping environmental damage, endangered species, and human made disasters has become one of the focal point of affective knowledge production. These ‘more-than-humangeographies’ practices include notions of species, space and territory, and movement towards a new political ecology...

    Affective dependency is characterized by emotional distress (insecure attachment) and dependency to another person with a low self-esteem and reassurance need. The paper proposes a reflection on the definition of emotional dependency and the confusion caused by various denominations. Overprotective and authoritarian parenting, cultural and socio-environmental factors may contribute to the development of dependent personality. Psychological epigenetic factors, such as early socio-emotional trauma could on neuronal circuits in prefronto-limbic regions that are essential for emotional behaviour.We also focus on the interrelations between dependent personality, domestic violence and addictions. The objective for the clinician is to propose a restoration of self-esteem and therapeutic strategies focused on autonomy. PMID:23888587

    In affective psychology, there is a persistent controversy about the number, the nature and the definition of the affect structure dimensions. Responding to the methodological criticisms addressed to the preceding studies, we conciliated the principal theories regarding the affect structure with the same experimental setting. In particular, using the semantic items all around the circumplex we found three bipolar independent dimensions and using only the PANAS semantic items, we found two uni...

The term affect regulation in psychoanalytic literature refers to phenomena which are often described by the concept of alexithymia.

    2016-07-01

    The objective of the present work was the characterization of mechanisms by which affective experiences are elicited in observers when watching dance movements. A total of 203 dance stimuli from a normed stimuli library were used in a series of independent experiments. The following measures were obtained: (i) subjective measures of 97 dance-naïve participants' affective responses (Likert scale ratings, interviews); and (ii) objective measures of the physical parameters of the stimuli (motion energy, luminance), and of the movements represented in the stimuli (roundedness, impressiveness). Results showed that (i) participants' ratings of felt and perceived affect differed, (ii) felt and perceived valence but not arousal ratings correlated with physical parameters of the stimuli (motion energy and luminance), (iii) roundedness in posture shape was related to the experience of more positive emotion than edgy shapes (1 of 3 assessed rounded shapes showed a clear effect on positiveness ratings while a second reached trend level significance), (iv) more impressive movements resulted in more positive affective responses, (v) dance triggered affective experiences through the imagery and autobiographical memories it elicited in some people, and (vi) the physical parameters of the video stimuli correlated only weakly and negatively with the aesthetics ratings of beauty, liking and interest. The novelty of the present approach was twofold; (i) the assessment of multiple affect-inducing mechanisms, and (ii) the use of one single normed stimulus set. The results from this approach lend support to both previous and present findings. Results are discussed with regards to current literature in the field of empirical aesthetics and affective neuroscience. PMID:27235953

    Full Text Available In the last decade studies on affect and emotions have become relevant in the social sciences. This is not just a fad guideline, but instead a simultaneous reader of public life changes and subjective experience, from which it is also being transformed the knowledge production. Such a trend has been known as ‘The Affective Turn’ within the Anglophone Academy. Here we will translate it as ‘El Giro Afectivo’. This turn, so far, has not dabbled in the social science literature that is written in Spanish. This paper draws on a singular panorama of discussions about contemporary social studies of affect and emotion, and it’s vertebrate by some of its expressions in the contemporary academy.

  17. Neurotransmitters affecting time perception

    Institute of Scientific and Technical Information of China (English)

    2007-01-01

    BACKGROUND:It has been demonstrated that dopamine and acetylcholine are the main neurotransmitters that affect time perception,which is also affected by other neurotransmitters.OBJECTIVE:To summarize how the neurotransmitter affect the time perception,and put forward the perspectives for further study on time perception.RETRIEVE STRATEGY:An online search for related literatures published in English was conducted in Elsevier SDOL(ScienceDirect Online)database from May 1990 to March 2007 using key words of "timing neurotransmitter".Totally 69 literatures were collected,and they were primarily checked.Inclusive criteria:Reviews and experimental studies;correlative studies of timing neurotransmitter.Exclusive criteria:Repeated studies.LITERATURE EVALUATION:The literatures were mainly sourced from Cognitive Brain Research and Neuroscience,and they were analyzed according to the inclusive criteria.Nineteen of them were involved,and all were experimental studies and reviews.DATA SYNTHESIS:The studies on time perception are developed mainly concentrating on dopamine and acetylcholine.Dopamine D2 receptors mainly affect the speed of internal clock.Dopamine receptors play an important role in both timing excitation and inhibition,which suggests the bi-directional regulation of dopamine.Injection of dopamine agonist can affect the attention to timing information.Injection of BW813U(antagonist of acetylcholine) can induce memory disorder,which indicates the effect of acetylcholine on timing memory,and further study shows that it is the effect of acetylcholine in precentral medial area.In a word,the study on the neurotransmitters affecting time perception is still at the primary stage.CONCLUSION:Dopamine and acetylcholine are the neurotransmitters known to be related to time perception.Dopamine in the basal ganglia is related to internal-clock in the range of seconds and minutes;Acetylcholine in prefrontal cortex is related to the mechanisms of temporal memory and attention

    Colorization of gray-scale images has attracted many attentions for a long time.An important role of image color is the conveyer of emotions (through color themes).The colorization with an undesired color theme is less useful,even it is semantically correct.However this has been rarely considered.Automatic colorization respecting both the semantics and the emotions is undoubtedly a challenge.In this paper,we propose a complete system for affective image colorization.We only need the user to assist object segmentation along with text labels and an affective word.First,the text labels along with other object characters are jointly used to filter the internet images to give each object a set of semantically correct reference images.Second,we select a set of color themes according to the affective word based on art theories.With these themes,a generic algorithm is used to select the best reference for each object,balancing various requirements.Finally,we propose a hybrid texture synthesis approach for colorization.To the best of our knowledge,it is the first system which is able to efficiently colorize a gray-scale image semantically by an emotionally controllable fashion.Our experiments show the effectiveness of our system,especially the benefit compared with the previous Markov random field (MRF) based method.

More broadly, the...... dissertation investigates the critical negotiation of the novel as a travelling genre in Japan in the beginning of the 20th century, and, more specifically, Sōseki’s work in relation to world literature and affect theory. Sōseki’s work is highly influential in Japan and East Asia, and his novels widely...... circulated beyond Japan. Using Sōseki’s theory as an example, and by comparing it to other theories, the dissertation argues that comparative literature needs to include not only more non-Western literature but also more non-Western literary theories in the ongoing debate of world literature.

    Full Text Available In this paper we sketch a new framework for affect elicitation, which is based on previous evolutionary and connectionist modeling and experimental work from our group. Affective monitoring is considered a local match-mismatch process within a module of the neural network. Negative affect is raised instantly by mismatches, incongruency, disfluency, novelty, incoherence, and dissonance, whereas positive affect follows from matches, congruency, fluency, familiarity, coherence, and resonance, at least when an initial mismatch can be solved quickly. Affective monitoring is considered an evolutionary-early conflict and change detection process operating at the same level as, for instance, attentional selection. It runs in parallel and imparts affective flavour to emotional behavior systems, which involve evolutionary-prepared stimuli and action tendencies related to for instance defensive, exploratory, attachment, or appetitive behavior. Positive affect is represented in the networks by high-frequency oscillations, presumably in the gamma band. Negative affect corresponds to more incoherent lower-frequency oscillations, presumably in the theta band. For affect to become conscious, large-scale synchronization of the oscillations over the network and the construction of emotional experiences are required. These constructions involve perceptions of bodily states and action tendencies, but also appraisals as well as efforts to regulate the emotion. Importantly, affective monitoring accompanies every kind of information processing, but conscious emotions, which result from the later integration of affect in a cognitive context, are much rarer events.

    Terracciano, Antonio; McCrae, Robert R.; Hagemann, Dirk; Costa, Paul T.

    2008-01-01

    Methodological arguments are usually invoked to explain variations in the structure of affect. Using self-rated affect from Italian samples (N = 600), we show that individual difference variables related to affective differentiation can moderate the observed structure. Indices of circumplexity (Browne, 1992) and congruence coefficients to the hypothesized target were used to quantify the observed structures. Results did not support the circumplex model as a universal structure. A circular structure with axes of activation and valence was approximated only among more affectively differentiated groups: students and respondents with high scores on Openness to Feelings and measures of negative emotionality. A different structure, with unipolar Positive Affect and Negative Affect factors, was observed among adults and respondents with low Openness to Feelings and negative emotionality. The observed structure of affect will depend in part on the nature of the sample studied. PMID:12932207

    1992-07-01

    Relationships between affect intensity and basal, evoked, and perceived cardiac arousal were investigated in 3 experiments. Affect intensity was assessed using Larsen and Diener's (1987) Affect Intensity Measure (AIM). Cardiac arousal was evoked with exercise in the 1st study and with mental arithmetic in the 2nd and 3rd. Perceived cardiac arousal was measured under optimal conditions using a standard heartbeat discrimination procedure. Women as a group scored higher on the AIM. Affect intensity was unrelated to basal or evoked cardiac arousal and was negatively related to perceived cardiac arousal in all 3 studies. Data suggest that affect intensity, although unrelated to actual physiological arousal, is negatively related to the accuracy with which individuals perceive their own arousal. Results are discussed within the context of an expanded arousal-regulation model (Blascovich, 1990). PMID:1494983

    Full Text Available The affective turn, which has already questioned dominant paradigms in many disciplinary fields including cultural studies, philosophy, political theory, anthropology, psychology and neuroscience, has started to attract more attention in the field of ethnomusicology, becoming a particularly vibrant stream of thought. Drawing on the voices that call for the historicisation of and critical deliberation on the field of affect studies, the article strives to show how theories of affect might expand dominant paradigms in ethnomusicology and also points to their limitations.

    Data collected in Romance and Scandinavian languages (N=474) in a superordinate category name production task indicate that a multiple-strategy approach would be more suitable for accounting of categorization in the affective domain instead of a prototype approach as suggested by previous studies....... This paper will highlight performance aspects which appear to be consistent with such an interpretation, as well as an important layman- expert knowledge asymmetry in affective categorization....

    This article provides a simple logical structure, in which affective concepts (i.e. concepts related to emotions and feelings) can be defined. The set of affects defined is similar to the set of emotions covered in the OCC model (Ortony A., Collins A., and Clore G. L.: The Cognitive Structure of Emotions. Cambridge University Press, 1988), but the model presented in this article is fully computationally defined.

    Full Text Available In this article, a concept of staging of unipolar affective illness (recurrent depression is presented. In respective subchapters, three most important aspects of this issue have been discussed: 1 staging of unipolar affective illness; 2 staging of treatment-resistant depression; and 3 conversion of unipolar into bipolar affective illness. The evidence for so called neuroprogression of the illness, accumulated in recent years, has allowed for a classification of staging based on a concept of allostasis and allostatic load. In the course of illness, changes in neuroendocrine system (mainly hypothalamic pituitary-adrenal (HPA axis, immunological system, mechanisms of oxidative stress, neurotransmitters, neurotrophic factors as well as structural and functional changes of the brain occur. In their paper of 2007, Fava and Tossani elaborated a concept of staging of unipolar affective illness presenting a continuum model of five consecutive stages with specific clinical features. In the present paper, a concept of treatment-resistant depression and staging of treatment resistance is presented in the context of several models. An important determinant of treatment-resistant depression is so called subthreshold bipolarity which is connected with worse efficacy of antidepressant drugs. In the course of illness, there is a possibility of changing diagnosis from recurrent depression into bipolar affective illness. The studies on this issue show that frequency of such diagnostic conversion is 1,5% of depressed patients per year.

    In English teaching and learning, listening ability is an important part of communicative competence, is a very practical integrated skill. It has been a difficult skill in second language acquisition for many students. Many Chinese students are skilled in reading, but often they tend to neglect the listening. However, owing to the higher requirements of many English tests and the great importance in communication, students begin to pay attention to develop their English listening skills. But there are many factors affecting listening, the paper mainly focuses on linguistic factors and non-linguistic factors that affect listening, to provide a theoretical basis to help exploring ways of improving listening and comprehension skills.

  18. Affective temperament and personal identity.

    Stanghellini, Giovanni; Rosfort, René

    2010-10-01

    The complex relationship between temperament and personal identity, and between these and mental disorders, is of critical interest to both philosophy and psychopathology. More than other living creatures, human beings are constituted and characterized by the interplay of their genotype and phenotype. There appears to be an explanatory gap between the almost perfect genetic identity and the individual differences among humans. One reason for this gap is that a human being is a person besides a physiological organism. We propose an outline of a theoretical model that might somewhat mitigate the explanatory discrepancies between physiological mechanisms and individual human emotional experience and behaviour. Arguing for the pervasive nature of human affectivity, i.e., for the assumption that human consciousness and behaviour is characterised by being permeated by affectivity; to envisage the dynamics of emotional experience, we make use of a three-levelled model of human personal identity that differentiates between factors that are simultaneously at work in the constitution of the individual human person: 1) core emotions, 2) affective temperament types/affective character traits, and 3) personhood. These levels are investigated separately in order to respect the methodological diversity among them (neuroscience, psychopathology, and philosophy), but they are eventually brought together in a hermeneutical account of human personhood.

    2012-09-01

    Full Text Available Abstract For optimal individual performance within any equestrian discipline horses must be in peak physical condition and have the correct psychological state. This review discusses the psychological factors that affect the performance of the horse and, in turn, identifies areas within the competition horse industry where current behavioral research and established behavioral modification techniques could be applied to further enhance the performance of animals. In particular, the role of affective processes underpinning temperament, mood and emotional reaction in determining discipline-specific performance is discussed. A comparison is then made between the training and the competition environment and the review completes with a discussion on how behavioral modification techniques and general husbandry can be used advantageously from a performance perspective.

    Full Text Available Abstract Background To evaluate the effect of food aroma on bite size, a semisolid vanilla custard dessert was delivered repeatedly into the mouth of test subjects using a pump while various concentrations of cream aroma were presented retronasally to the nose. Termination of the pump, which determined bite size, was controlled by the subject via a push button. Over 30 trials with 10 subjects, the custard was presented randomly either without an aroma, or with aromas presented below or near the detection threshold. Results Results for ten subjects (four females and six males, aged between 26 and 50 years, indicated that aroma intensity affected the size of the corresponding bite as well as that of subsequent bites. Higher aroma intensities resulted in significantly smaller sizes. Conclusions These results suggest that bite size control during eating is a highly dynamic process affected by the sensations experienced during the current and previous bites.

  11. Musical affect regulation in infancy.

    Science.gov (United States)

    Trehub, Sandra E; Ghazban, Niusha; Corbeil, Mariève

    2015-03-01

    Adolescents and adults commonly use music for various forms of affect regulation, including relaxation, revitalization, distraction, and elicitation of pleasant memories. Mothers throughout the world also sing to their infants, with affect regulation as the principal goal. To date, the study of maternal singing has focused largely on its acoustic features and its consequences for infant attention. We describe recent laboratory research that explores the consequences of singing for infant affect regulation. Such work reveals that listening to recordings of play songs can maintain 6- to 9-month-old infants in a relatively contented or neutral state considerably longer than recordings of infant-directed or adult-directed speech. When 10-month-old infants fuss or cry and are highly aroused, mothers' multimodal singing is more effective than maternal speech at inducing recovery from such distress. Moreover, play songs are more effective than lullabies at reducing arousal in Western infants. We explore the implications of these findings along with possible practical applications. PMID:25773634

    2007-01-01

    Seven-month-old zebrafish (Danio rerio) were fed four different diets to test the hypothesis that diet affects spawning success and resulting characteristics of eggs and offspring. The diets were: the recommended feeding regime for zebrafish (a mixture of Artemia, flake feed, and liver paste); Artemia; a flake feed; and a commercially available trout diet. The number of eggs laid and average egg diameter were significantly different as functions of male, female, and individual matings. Fish fed the flake diet produced significantly fewer eggs (mean, 116) than fish fed all other diets (means, 166-187). However, the percent hatch of eggs from fish fed the flake diet (62.5%) was significantly higher than from fish fed the trout diet (19.5%). The percentages of hatched eggs from fish fed the control diet (36.2%) or Artemia (35.6%) were not significantly different from each other or from fish fed the other two diets. Wet weight and diameter of eggs were not significantly affected by diet. Larval length was significantly higher from parents fed the flake diet (14.5 mm) compared to larvae from parents fed Artemia (13.7 mm). Length of larvae from fish fed the control or trout diets was intermediate and not significantly different from fish fed the flake diet or Artemia. Larval weight was not significantly affected by dietary treatment, but offspring from fish fed the flake diet were heavier than larvae from adults fed any of the other diets. Feeding adult zebrafish the flake diet alone resulted in more viable offspring and larger larvae and is a simpler feeding regime than the current recommendation. The authors recommend feeding adult zebrafish flake diets to satiation three times daily for maximum production of viable offspring. PMID:18041944

    Frankel and Romer [Frankel, J., Romer, D., 1999. Does trade cause growth? American Economic Review 89 (3), 379-399] documented positive effects of geographically determined trade openness on economic growth. At the same time, critics fear that openness can lead to a "race to the bottom" that increases pollution and reduces government resources for investments in health and education. We use Frankel and Romer's gravity model of trade to examine how openness to trade affects children. Overall, we find little harm from trade, and potential benefits largely through slightly faster GDP growth. PMID:16303196

    The progress in the field of affective computing enables the realization of affective consumer products, affective games, and affective art. This paper describes the affective interactive art system Mood Swings, which interprets and visualizes affect expressed by a person. Mood Swings is founded on the integration of a framework for affective movements and a color model. This enables Mood Swings to recognize affective movement characteristics as expressed by a person and display a color that matches the expressed emotion. With that, a unique interactive system is introduced, which can be considered as art, a game, or a combination of both.

The psychological consequences and the impact on social interactions may be substantial. Although it is most commonly misidentified as a mood disorder, particularly depression or a bipolar disorder, there are characteristic features that can be recognized clinically or assessed by validated scales, resulting in accurate identification of PBA, and thus permitting proper management and treatment. Mechanistically, PBA is a disinhibition syndrome in which pathways involving serotonin and glutamate are disrupted. This knowledge has permitted effective treatment for many years with antidepressants, particularly tricyclic antidepressants and selective serotonin reuptake inhibitors. A recent therapeutic breakthrough occurred with the approval by the Food and Drug Administration of a dextromethorphan/quinidine combination as being safe and effective for treatment of PBA. Side effect profiles and contraindications differ for the various treatment options, and the clinician must be familiar with these when choosing the best therapy for an individual, particularly elderly patients and those with multiple comorbidities and concomitant medications.Keywords: pseudobulbar affect, emotional lability, depression, amyotrophic lateral sclerosis, multiple sclerosis

    2016-01-01

    Dietary intake and nutritional status of individuals are important factors affecting mental health and the development of psychiatric disorders. Majority of scientific evidence relating to mental health focuses on depression, cognitive function, and dementia, and limited evidence is available about other psychiatric disorders including schizophrenia. As life span of human being is increasing, the more the prevalence of mental disorders is, the more attention rises. Lists of suggested nutritional components that may be beneficial for mental health are omega-3 fatty acids, phospholipids, cholesterol, niacin, folate, vitamin B6, and vitamin B12. Saturated fat and simple sugar are considered detrimental to cognitive function. Evidence on the effect of cholesterol is conflicting; however, in general, blood cholesterol levels are negatively associated with the risk of depression. Collectively, the aims of this review are to introduce known nutritional factors for mental health, and to discuss recent issues of the nutritional impact on cognitive function and healthy brain aging.

    Full Text Available This paper consists of a case history and an overview of the relationship, aetiology, and treatment of comorbid bipolar disorder migraine patients. A MEDLINE literature search was used. Terms for the search were bipolar disorder bipolar depression, mania, migraine, mood stabilizer. Bipolar disorder and migraine cooccur at a relatively high rate. Bipolar II patients seem to have a higher risk of comorbid migraine than bipolar I patients have. The literature on the common roots of migraine and bipolar disorder, including both genetic and neuropathological approaches, is broadly discussed. Moreover, bipolar disorder and migraine are often combined with a variety of other affective disorders, and, furthermore, behavioural factors also play a role in the origin and course of the diseases. Approach to treatment options is also difficult. Several papers point out possible remedies, for example, valproate, topiramate, which acts on both diseases, but no first-choice treatments have been agreed upon yet.

    Full Text Available Despite the wealth of theoretical claims about the emotion of humiliation and its effect on human relations, there has been a lack of empirical research investigating what it means to experience humiliation. We studied the affective characteristics of humiliation, comparing the emotional experience of intergroup humiliation to two other emotions humiliation is often confused with: anger and shame. The defining characteristics of humiliation were low levels of guilt and high levels of other-directed outrage (like anger and unlike shame, and high levels of powerlessness (like shame and unlike anger. Reasons for the similarities and differences of humiliation with anger and shame are discussed in terms of perceptions of undeserved treatment and injustice. Implications for understanding the behavioral consequences of humiliation and future work investigating the role of humiliation in social life are discussed.

  4. Does health affect portfolio choice?

    Science.gov (United States)

    Love, David A; Smith, Paul A

    2010-12-01

    A number of recent studies find that poor health is empirically associated with a safer portfolio allocation. It is difficult to say, however, whether this relationship is truly causal. Both health status and portfolio choice are influenced by unobserved characteristics such as risk attitudes, impatience, information, and motivation, and these unobserved factors, if not adequately controlled for, can induce significant bias in the estimates of asset demand equations. Using the 1992-2006 waves of the Health and Retirement Study, we investigate how much of the connection between health and portfolio choice is causal and how much is due to the effects of unobserved heterogeneity. Accounting for unobserved heterogeneity with fixed effects and correlated random effects models, we find that health does not appear to significantly affect portfolio choice among single households. For married households, we find a small effect (about 2-3 percentage points) from being in the lowest of five self-reported health categories. PMID:19937612

    Full Text Available Rheumatoid arthritis (RA is a chronic, systemic, autoimmune inflammatory disorder that is characterized by joint inflammation, erosive properties and symmetric multiple joint involvement. Temporomandibular joint (TMJ is very rare to be affected in the early phase of the disease, thus posing diagnostic challenges for the dentist. Conventional radiographs fail to show the early lesions due to its limitations. More recently cone-beam computed tomography (CBCT has been found to diagnose the early degenerative changes of TMJ and hence aid in the diagnosis of the lesions more accurately. Our case highlights the involvement of TMJ in RA and the role of advanced imaging (CBCT in diagnosing the bony changes in the early phase of the disease.

    Ash in fire affected ecosystems Ash lefts an important footprint in the ecosystems and has a key role in the immediate period after the fire (Bodi et al., 2014; Pereira et al., 2015). It is an important source of nutrients for plant recover (Pereira et al., 2014a), protects soil from erosion and controls soil hydrological process as runoff, infiltration and water repellency (Cerda and Doerr, 2008; Bodi et al., 2012, Pereira et al., 2014b). Despite the recognition of ash impact and contribution to ecosystems recuperation, it is assumed that we still have little knowledge about the implications of ash in fire affected areas. Regarding this situation we wanted to improve our knowledge in this field and understand the state of the research about fire ash around world. The special issue about "The role of ash in fire affected ecosystems" currently in publication in CATENA born from the necessity of joint efforts, identify research gaps, and discuss future cooperation in this interdisciplinary field. This is the first special issue about fire ash in the international literature. In total it will be published 10 papers focused in different aspects of the impacts of ash in fire affected ecosystems from several parts of the world: • Fire reconstruction using charcoal particles (Burjachs and Espositio, in press) • Ash slurries impact on rheological properties of Runoff (Burns and Gabet, in press) • Methods to analyse ash conductivity and sorbtivity in the laboratory and in the field (Balfour et al., in press) • Termogravimetric and hydrological properties of ash (Dlapa et al. in press) • Effects of ash cover in water infiltration (Leon et al., in press) • Impact of ash in volcanic soils (Dorta Almenar et al., in press; Escuday et al., in press) • Ash PAH and Chemical extracts (Silva et al., in press) • Microbiology (Barreiro et al., in press; Lombao et al., in press) We believe that this special issue will contribute importantly to the better understanding of

  7. Twitter, Journalism and Affective Labour

    Full Text Available The rise of the network aspects of journalism in the context of social mediasuch as Twitter, and the increased importance accorded to community building and maintenance as well as to reciprocity, point to the need to take into account the affective part of journalistic labour. This refers to these aspects of journalistic work that are linked to the creation of networks and communities, to interactions with readers and the forming of bonds between journalists and their readers. An analysis of the affective labour of journalists on Twitter, we argue, is necessary in order to understand the potential and ambiguities of this part of their labour. Based on a set of in-depth interviews with Twitter journalists, this article found three main repertoires of affective labour: the organic relations repertoire, which points to the increasing importance of authenticity as a means of establishing credibility on Twitter; the temporal repertoire; and the repertoire of responsibility. The importance of the affective labour of journalism is found in its biopolitical productivity. The development of an organic relationship with followers, the emergence of stronger bonds between core groups that then become communities, the extension of care and help to the network, are all evidence of the importance of this biopolitical productivity and point to the construction of a new and potentially more radical sociopolitical role for journalism. However, this potential is ambiguous insofar as these elements contain unresolved tensions and ambiguities. These include the trade in selves and the associated commodification; the re-formulation of time, especially its diachronic dimension, as accumulation of social capital; the role of reciprocity and responsibility in reproducing inequalities; and care as care for only those deemed deserving. These ambiguities severely undermine and limit the potentials of affective labour, pointing to the need to develop a purposeful political

    1998-01-01

    Full Text Available Significant advances have been made in our knowledge of forage seed physiology, technology, and stand establishment practices; however, stand establishment continues to be one of the most common production problems affecting forage crops in the USA. There is a need for research on stand establishment of forage crops under abiotic and biotic stress. Although the forage seed industry produces and markets seed of high quality, new methods of assessing seed vigor are needed and their use should be expanded in the industry to enable matching seed lot performance to specific environmental conditions where performance can be maximized. Seed treatment and seed coating are used in the forage seed industry, and studies have shown they are of benefit in some environments. There is an increase in no-tillage seeding of forage crops, but improvements in the no-tillage planting equipment are needed to make them better suited to small seeds. Other recent developments in seeding techniques include broadcasting seed with dry granular and fluid fertilizers, which improves the efficiency of the seeding operation.

  9. Does methamphetamine affect bone metabolism?

    International Nuclear Information System (INIS)

    There is a close relationship between the central nervous system activity and bone metabolism. Therefore, methamphetamine (METH), which stimulates the central nervous system, is expected to affect bone turnover. The aim of this study was to investigate the role of METH in bone metabolism. Mice were divided into 3 groups, the control group receiving saline injections, and the 5 and 10 mg/kg METH groups (n = 6 in each group). All groups received an injection of saline or METH every other day for 8 weeks. Bone mineral density (BMD) was assessed by X-ray computed tomography. We examined biochemical markers and histomorphometric changes in the second cancellous bone of the left femoral distal end. The animals that were administered 5 mg/kg METH showed an increased locomotor activity, whereas those receiving 10 mg/kg displayed an abnormal and stereotyped behavior. Serum calcium and phosphorus concentrations were normal compared to the controls, whereas the serum protein concentration was lower in the METH groups. BMD was unchanged in all groups. Bone formation markers such as alkaline phosphatase and osteocalcin significantly increased in the 5 mg/kg METH group, but not in the 10 mg/kg METH group. In contrast, bone resorption markers such as C-terminal telopeptides of type I collagen and tartrate-resistant acid phosphatase 5b did not change in any of the METH groups. Histomorphometric analyses were consistent with the biochemical markers data. A significant increase in osteoblasts, especially in type III osteoblasts, was observed in the 5 mg/kg METH group, whereas other parameters of bone resorption and mineralization remained unchanged. These results indicate that bone remodeling in this group was unbalanced. In contrast, in the 10 mg/kg METH group, some parameters of bone formation were significantly or slightly decreased, suggesting a low turnover metabolism. Taken together, our results suggest that METH had distinct dose-dependent effects on bone turnover and that

  10. [Harmful practices affecting women's health].

    Science.gov (United States)

    1990-07-01

    The harmful practices discussed in this article are based on case histories form the Central Maternity in Niamey, yet these practices universally affect women throughout Africa. Nutritional taboos are aimed at certain diseases such as measles, diarrhea, dysentery, malnutrition and anemia and consumption of foods rich in proteins and lipids are forbidden. Children are forbidden from eating eggs; pregnant women are forbidden from eating fruits and vegetables because of the fear of hemorrhaging from the sugar content in the fruit; camel meat is forbidden for fear of extending the pregnancy. Female circumcision, a dangerous practice, especially during childbirth, causes many medical problems that remain permanent. Adolescent pregnancy and marriages are practiced to avoid delinquency among children; yet such practices take place because of arranged marriages for a dowry to young men or to older rich men and these forced marriages to adolescents are the causes of increases in divorce, prostitution and desertion. These young marriages have serious consequences on the health status of the mother and the infant, often leading to maternal and infant death. The high level of fertility in Niger is a response to the social structure of the family. It is a patrilineal system that encourages women to have many children, especially sons. In Niger, pregnancy is surrounded by supernatural and mysterious forces, where a child is the intervention for ancestral spirits. In Islam a child is considered a "Gift of God". A woman is expected to work until the delivery of her baby otherwise she is jeered by her neighbors. During delivery women are not expected to cry or show any pain for fear of dishonoring her family irregardless of any medical compilations she faces. Women in Africa are exploited as free labor, deteriorate and age rapidly, are generally illiterate and are not protected under any laws. PMID:12342832

  11. A Multimodal Theory of Affect Diffusion.

    Science.gov (United States)

    Peters, Kim; Kashima, Yoshihisa

    2015-09-01

    There is broad consensus in the literature that affect diffuses through social networks (such that a person may "acquire" or "catch" an affective state from his or her social contacts). It is further assumed that affect diffusion primarily occurs as the result of people's tendencies to synchronize their affective actions (such as smiles and frowns). However, as we show, there is a lack of clarity in the literature about the substrate and scope of affect diffusion. One consequence of this is a difficulty in distinguishing between affect diffusion and several other affective influence phenomena that look similar but have very different consequences. There is also a growing body of evidence that action synchrony is unlikely to be the only, or indeed the most important, pathway for affect diffusion. This paper has 2 key aims: (a) to craft a formal definition of affect diffusion that does justice to the core of the phenomenon while distinguishing it from other phenomena with which it is frequently confounded and (b) to advance a theory of the mechanisms of affect diffusion. This theory, which we call the multimodal theory of affect diffusion, identifies 3 parallel multimodal mechanisms that may act as routes for affect diffusion. It also provides a basis for novel predictions about the conditions under which affect is most likely to diffuse. PMID:26011791

  19. Factors Affecting Aerosol Radiative Forcing

    Wang, Jingxu; Lin, Jintai; Ni, Ruijing

    2016-04-01

    Rapid industrial and economic growth has meant a large amount of aerosols in the atmosphere with strong radiative forcing (RF) upon the climate system. Over parts of the globe, the negative forcing of aerosols has overcompensated for the positive forcing of greenhouse gases. Aerosol RF is determined by emissions and various chemical-transport-radiative processes in the atmosphere, a multi-factor problem whose individual contributors have not been well quantified. In this study, we analyze the major factors affecting RF of secondary inorganic aerosols (SIOAs, including sulfate, nitrate and ammonium), primary organic aerosol (POA), and black carbon (BC). We analyze the RF of aerosols produced by 11 major regions across the globe, including but not limited to East Asia, Southeast Asia, South Asia, North America, and Western Europe. Factors analyzed include population size, per capita gross domestic production (GDP), emission intensity (i.e., emissions per unit GDP), chemical efficiency (i.e., mass per unit emissions) and radiative efficiency (i.e., RF per unit mass). We find that among the 11 regions, East Asia produces the largest emissions and aerosol RF, due to relatively high emission intensity and a tremendous population size. South Asia produce the second largest RF of SIOA and BC and the highest RF of POA, in part due to its highest chemical efficiency among all regions. Although Southeast Asia also has large emissions, its aerosol RF is alleviated by its lowest chemical efficiency. The chemical efficiency and radiative efficiency of BC produced by the Middle East-North Africa are the highest across the regions, whereas its RF is lowered by a small per capita GDP. Both North America and Western Europe have low emission intensity, compensating for the effects on RF of large population sizes and per capita GDP. There has been a momentum to transfer industries to Southeast Asia and South Asia, and such transition is expected to continue in the coming years. The

    The affect-as-information framework posits that affect is embodied information about value and importance. The valence dimension of affect provides evaluative information about stimulus objects, which plays a role in judgment and decisionmaking. Affect can also provide evaluative information about one's own cognitions and response inclinations, information that guides thinking and reasoning. In particular, positive affect often promotes, and negative affect inhibits, accessible responses or d...

    2007-11-01

    Automatic affective expression recognition has attracted more and more attention of researchers from different disciplines, which will significantly contribute to a new paradigm for human computer interaction (affect-sensitive interfaces, socially intelligent environments) and advance the research in the affect-related fields including psychology, psychiatry, and education. Multimodal information integration is a process that enables human to assess affective states robustly and flexibly. In order to understand the richness and subtleness of human emotion behavior, the computer should be able to integrate information from multiple sensors. We introduce in this paper our efforts toward machine understanding of audio-visual affective behavior, based on both deliberate and spontaneous displays. Some promising methods are presented to integrate information from both audio and visual modalities. Our experiments show the advantage of audio-visual fusion in affective expression recognition over audio-only or visual-only approaches.

    Full Text Available Aim: The aim was to study the chromosome analysis of arsenic affected cattle. Materials and Methods: 27 female cattle (21 arsenic affected and 6 normal were selected for cytogenetical study. The blood samples were collected, incubated, and cultured using appropriate media and specific methods. The samples were analyzed for chromosome number and morphology, relative length of the chromosome, arm ratio, and centromere index of X chromosome and chromosomal abnormalities in arsenic affected cattle to that of normal ones. Results: The diploid number of metaphase chromosomes in arsenic affected cattle as well as in normal cattle were all 2n=60, 58 being autosomes and 2 being sex chromosomes. From the centromeric position, karyotyping studies revealed that all the 29 pair of autosomes was found to be acrocentric or telocentric, and the sex chromosomes (XX were submetacentric in both normal and arsenic affected cattle. The relative length of all the autosome pairs and sex chrosomosome pair was found to be higher in normal than that of arsenic affected cattle. The mean arm ratio of X-chromosome was higher in normal than that of arsenic affected cattle, but it is reverse in case of centromere index value of X-chromosome. There was no significant difference of arm ratio and centromere index of X-chromosomes between arsenic affected and normal cattle. No chromosomal abnormalities were found in arsenic affected cattle. Conclusion: The chromosome analysis of arsenic affected cattle in West Bengal reported for the first time in this present study which may serve as a guideline for future studies in other species. These reference values will also help in comparison of cytological studies of arsenic affected cattle to that of various toxicants.

  15. Nonverbal synchrony and affect in dyadic interactions

    2014-11-01

    Full Text Available In an experiment on dyadic social interaction, we invited participants to verbal interactions in cooperative, competitive, and 'fun task' conditions. We focused on the link between interactants' affectivity and their nonverbal synchrony, and explored which further variables contributed to affectivity: interactants' personality traits, sex, and the prescribed interaction tasks. Nonverbal synchrony was quantified by the coordination of interactants' body movement, using an automated video-analysis algorithm (Motion Energy Analysis, MEA. Traits were assessed with standard questionnaires of personality, attachment, interactional style, psychopathology and interpersonal reactivity. We included 168 previously unacquainted individuals who were randomly allocated to same-sex dyads (84 females, 84 males, mean age 27.3 years. Dyads discussed four topics of general interest drawn from an urn of eight topics, and finally engaged in a fun interaction. Each interaction lasted five minutes. In between interactions, participants repeatedly assessed their affect. Using hierarchical linear modeling, we found moderate to strong effect sizes for synchrony to occur, especially in competitive and fun task conditions. Positive affect was associated positively with synchrony, negative affect was associated negatively. As for causal direction, data supported the interpretation that synchrony entailed affect rather than vice versa. The link between nonverbal synchrony and affect was strongest in female dyads. The findings extend previous reports of synchrony and mimicry associated with emotion in relationships and suggest a possible mechanism of the synchrony-affect correlation.

  17. Affective Scaffolds, Expressive Arts, and Cognition

    Science.gov (United States)

    Maiese, Michelle

    2016-01-01

    Some theorists have argued that elements of the surrounding world play a crucial role in sustaining and amplifying both cognition and emotion. Such insights raise an interesting question about the relationship between cognitive and affective scaffolding: in addition to enabling the realization of specific affective states, can an affective niche also enable the realization of certain cognitive capacities? In order to gain a better understanding of this relationship between affective niches and cognition, I will examine the use of expressive arts in the context of psychotherapy and peacebuilding. In these settings, environmental resources and interpersonal scaffolds not only evoke emotion and encourage the adoption of particular bodily affective styles, but also support the development of capacities for self-awareness and interpersonal understanding. These affective scaffolds play a crucial role in therapy and peacebuilding, in fact, insofar as they facilitate the development of self-knowledge, enhance capacities associated with social cognition, and build positive rapport and trust among participants. I will argue that this is because affectivity is linked to the way that subjects frame and attend to their surroundings. Insofar as the regulation and modification of emotion goes hand in hand with opening up new interpretive frames and establishing new habits of mind, the creation of an affective niche can contribute significantly to various modes of cognition.

    The affect-as-information framework posits that affect is embodied information about value and importance. The valence dimension of affect provides evaluative information about stimulus objects, which plays a role in judgment and decisionmaking. Affect can also provide evaluative information about one's own cognitions and response inclinations, information that guides thinking and reasoning. In particular, positive affect often promotes, and negative affect inhibits, accessible responses or dominant modes of thinking. Affect thus moderates many of the textbook phenomena in cognitive psychology. In the current review, we suggest additionally that the arousal dimension of affect amplifies reactions, leading to intensified evaluations, increased reliance on particular styles of learning, and enhanced long-term memory for events. We conclude that whereas valenced affective cues serve as information about value, the arousal dimension provides information about urgency or importance. PMID:25067943

    Objective. We aim to develop and evaluate an affective brain–computer music interface (aBCMI) for modulating the affective states of its users. Approach. An aBCMI is constructed to detect a user's current affective state and attempt to modulate it in order to achieve specific objectives (for example, making the user calmer or happier) by playing music which is generated according to a specific affective target by an algorithmic music composition system and a case-based reasoning system. The system is trained and tested in a longitudinal study on a population of eight healthy participants, with each participant returning for multiple sessions. Main results. The final online aBCMI is able to detect its users current affective states with classification accuracies of up to 65% (3 class, p\\lt 0.01) and modulate its user's affective states significantly above chance level (p\\lt 0.05). Significance. Our system represents one of the first demonstrations of an online aBCMI that is able to accurately detect and respond to user's affective states. Possible applications include use in music therapy and entertainment.

  7. Embodied affectivity: on moving and being moved.

    2014-01-01

    There is a growing body of research indicating that bodily sensation and behavior strongly influences one's emotional reaction toward certain situations or objects. On this background, a framework model of embodied affectivity is suggested: we regard emotions as resulting from the circular interaction between affective qualities or affordances in the environment and the subject's bodily resonance, be it in the form of sensations, postures, expressive movements or movement tendencies. Motion and emotion are thus intrinsically connected: one is moved by movement (perception; impression; affection) and moved to move (action; expression; e-motion). Through its resonance, the body functions as a medium of emotional perception: it colors or charges self-experience and the environment with affective valences while it remains itself in the background of one's own awareness. This model is then applied to emotional social understanding or interaffectivity which is regarded as an intertwinement of two cycles of embodied affectivity, thus continuously modifying each partner's affective affordances and bodily resonance. We conclude with considerations of how embodied affectivity is altered in psychopathology and can be addressed in psychotherapy of the embodied self. PMID:24936191

  9. Ventricular enlargement in patients with affective disorders

    International Nuclear Information System (INIS)

    Ventricular enlargement was determined using linear measurement on MR images in a total of 71 patients with affective disorders, including bipolar affective disorder (41) and depression (30). Fourty-one healthy persons served as controls. Evans ratio, Huckman number and minimum distance of caudate nuclei (MDCN) were used as indices for ventricular enlargment. No significant difference in Evans ratio was observed between both the group of bipolar affective disorder and the group of depression and the control group. Nor did it correlate with age in any of the groups. Huckman number was significantly higher in the group of bipolar affective disorder than the other two groups. It positively correlated with age in the group of depression. MDCN was significantly increased in the group of bipolar affective disorder, as compared with the control group; and there was a positive correlation between MDCN and age in both the group of dipolar affective disorder and the group of depression. In conclusion, ventricular enlargement was dependent upon aging in affetive disorder patients. This tendency was more noticeable in the group of depression. In addition, atrophy of the caudate nuclei was likely to be severer in the group of dipolar affective disorder than the group of depression. (N.K.)

  10. Implicit processing of visual emotions is affected by sound-induced affective states and individual affective traits.

    Directory of Open Access Journals (Sweden)

    Tiziana Quarto

    Full Text Available The ability to recognize emotions contained in facial expressions are affected by both affective traits and states and varies widely between individuals. While affective traits are stable in time, affective states can be regulated more rapidly by environmental stimuli, such as music, that indirectly modulate the brain state. Here, we tested whether a relaxing or irritating sound environment affects implicit processing of facial expressions. Moreover, we investigated whether and how individual traits of anxiety and emotional control interact with this process. 32 healthy subjects performed an implicit emotion processing task (presented to subjects as a gender discrimination task while the sound environment was defined either by a a therapeutic music sequence (MusiCure, b a noise sequence or c silence. Individual changes in mood were sampled before and after the task by a computerized questionnaire. Additionally, emotional control and trait anxiety were assessed in a separate session by paper and pencil questionnaires. Results showed a better mood after the MusiCure condition compared with the other experimental conditions and faster responses to happy faces during MusiCure compared with angry faces during Noise. Moreover, individuals with higher trait anxiety were faster in performing the implicit emotion processing task during MusiCure compared with Silence. These findings suggest that sound-induced affective states are associated with differential responses to angry and happy emotional faces at an implicit stage of processing, and that a relaxing sound environment facilitates the implicit emotional processing in anxious individuals.

    2006-12-01

    Full Text Available The intersubjective theory that Sartre proposed in Being and Nothingness contends that human encounters are necessarily reifying. The author proposes that one of the constitutive theoretical elements of this pessimistic view of human encounters is Sartre’s conception of affectivity as a degradation of consciousness. The author explores this vision of affection that Sartre initially developed in his essay Outline of a Theory of Emotions, and concludes that it was this mode of understanding affectivity that later decisively influenced his contention in Being and Nothingness that the essence of human relations is conflict.

    Full Text Available Teaching is highly charged with feeling, aroused by and directed towards not just people, but also values and ideals (Garritz, 2010. Emotions and feelings greatly affect the way the students learn and acquire knowledge. There must be a balance between the three domains of learning because once one domain is left behind, the other domains will be affected. The purpose of this study is to determine nurse educators’ affective teaching strategies. Specifically, it assessed the strategies of nurse educators on how to develop the affective domain of student nurses. In addition, the study assessed the values of student nurses in terms of God-centeredness, Leadership, Integrity, and Nationalism. Lastly, the researchers proposed innovative teaching methodologies to enhance the attitudes of nursing students. This study used descriptive research design. The respondents of the study were the nursing students and clinical instructors of Lyceum of the Philippines University – Batangas. 190 student nurses were chosen through stratified random sampling while 10 clinical instructors were chosen based on the number of times they handled the students both in lecture and clinical area. The instruments were selfmade and standardized questionnaire and interview guide to obtain the data needed for the study. The data gathered are compiled, organized and tabulated for statistical treatment. Weighted mean was utilized to compute the quantitative data whereas the interview was used to form the qualitative analysis. Role modelling is the most common strategy of nurse educators to enhance the affective domain of student nurses. Their actions consciously and unconsciously affecting the attitude of the students. Hence, confidence among the students needs most attention in developing affective domain as it produce change in other values presented in the study. The proposed teaching strategies aim to enhance the affective domain of nursing students in line with the

  5. Stability of Facial Affective Expressions in Schizophrenia

    2012-01-01

    Full Text Available Thirty-two videorecorded interviews were conducted by two interviewers with eight patients diagnosed with schizophrenia. Each patient was interviewed four times: three weekly interviews by the first interviewer and one additional interview by the second interviewer. 64 selected sequences where the patients were speaking about psychotic experiences were scored for facial affective behaviour with Emotion Facial Action Coding System (EMFACS. In accordance with previous research, the results show that patients diagnosed with schizophrenia express negative facial affectivity. Facial affective behaviour seems not to be dependent on temporality, since within-subjects ANOVA revealed no substantial changes in the amount of affects displayed across the weekly interview occasions. Whereas previous findings found contempt to be the most frequent affect in patients, in the present material disgust was as common, but depended on the interviewer. The results suggest that facial affectivity in these patients is primarily dominated by the negative emotions of disgust and, to a lesser extent, contempt and implies that this seems to be a fairly stable feature.

  6. Flexible control in processing affective and non-affective material predicts individual differences in trait resilience.

    Genet, Jessica J; Siemer, Matthias

    2011-02-01

    Trait resilience is a stable personality characteristic that involves the self-reported ability to flexibly adapt to emotional events and situations. The present study examined cognitive processes that may explain individual differences in trait resilience. Participants completed self-report measures of trait resilience, cognitive flexibility and working memory capacity tasks, and a novel affective task-switching paradigm that assesses the ability to flexibly switch between processing the affective versus non-affective qualities of affective stimuli (i.e., flexible affective processing). As hypothesised, cognitive flexibility and flexible affective processing were unique predictors of trait resilience. Working memory capacity was not predictive of trait resilience, indicating that trait resilience is tied to specific cognitive processes rather than overall better cognitive functioning. Cognitive flexibility and flexible affective processing were not associated with other trait measures, suggesting that these flexibility processes are unique to trait resilience. This study was among the first to investigate the cognitive abilities underlying trait resilience. PMID:21432680

    Flaig, Nicole K; Large, Edward W

    2014-01-01

    Is there something special about the way music communicates feelings? Theorists since Meyer (1956) have attempted to explain how music could stimulate varied and subtle affective experiences by violating learned expectancies, or by mimicking other forms of social interaction. Our proposal is that music speaks to the brain in its own language; it need not imitate any other form of communication. We review recent theoretical and empirical literature, which suggests that all conscious processes consist of dynamic neural events, produced by spatially dispersed processes in the physical brain. Intentional thought and affective experience arise as dynamical aspects of neural events taking place in multiple brain areas simultaneously. At any given moment, this content comprises a unified "scene" that is integrated into a dynamic core through synchrony of neuronal oscillations. We propose that (1) neurodynamic synchrony with musical stimuli gives rise to musical qualia including tonal and temporal expectancies, and that (2) music-synchronous responses couple into core neurodynamics, enabling music to directly modulate core affect. Expressive music performance, for example, may recruit rhythm-synchronous neural responses to support affective communication. We suggest that the dynamic relationship between musical expression and the experience of affect presents a unique opportunity for the study of emotional experience. This may help elucidate the neural mechanisms underlying arousal and valence, and offer a new approach to exploring the complex dynamics of the how and why of emotional experience. PMID:24672492

    Affective presence is a novel personality construct that describes the tendency of individuals to make their interaction partners feel similarly positive or negative. We adopt this construct, together with the input-process-output model of teamwork, to understand how team leaders influence team interaction and innovation performance. In 2 multisource studies, based on 350 individuals working in 87 teams of 2 public organizations and 734 individuals working in 69 teams of a private organization, we tested and supported hypotheses that team leader positive affective presence was positively related to team information sharing, whereas team leader negative affective presence was negatively related to the same team process. In turn, team information sharing was positively related to team innovation, mediating the effects of leader affective presence on this team output. The results indicate the value of adopting an interpersonal individual differences approach to understanding how affect-related characteristics of leaders influence interaction processes and complex performance in teams.

    2008-01-01

    A central hypothesis of classical motivation theory is that affect underlies motivation and its behavioural manifestations. However, this has been largely ignored in the past 30 years because social cognitivism has been the dominant theory. As a result, studies have concentrated on social cognitive processes when analysing those factors that…

  11. Sequence Affects the Cyclization of DNA Minicircles.

    Understanding how the sequence of a DNA molecule affects its dynamic properties is a central problem affecting biochemistry and biotechnology. The process of cyclizing short DNA, as a critical step in molecular cloning, lacks a comprehensive picture of the kinetic process containing sequence information. We have elucidated this process by using coarse-grained simulations, enhanced sampling methods, and recent theoretical advances. We are able to identify the types and positions of structural defects during the looping process at a base-pair level. Correlations along a DNA molecule dictate critical sequence positions that can affect the looping rate. Structural defects change the bending elasticity of the DNA molecule from a harmonic to subharmonic potential with respect to bending angles. We explore the subelastic chain as a possible model in loop formation kinetics. A sequence-dependent model is developed to qualitatively predict the relative loop formation time as a function of DNA sequence. PMID:26938490

    Human activities are largely affecting coastal communities worldwide. Recreational perturbations have been overlooked in comparison to other perturbations, yet they are potential threats to marine biodiversity. They affect coastal communities in different ways, underpinning consistent shifts in fish and invertebrates assemblages. Several sites were sampled subjected to varying effects by recreational fishermen (low and high pressure) and scuba divers (low and high) in an overpopulated Atlantic island. Non-consistent differences in ecological, trophic and functional diversity were found in coastal communities, considering both factors ("diving" and "fishing"). Multivariate analyses only showed significant differences in benthic invertebrates between intensively-dived and non-dived sites. The lack of clear trends may be explained by the depletion of coastal resources in the study area, an extensively-affected island by overfishing.

  13. Affective privilege: Asymmetric interference by emotional distracters

    Directory of Open Access Journals (Sweden)

    TobiasEgner

    2011-09-01

    Full Text Available Numerous theories posit that affectively salient stimuli are privileged in their capacity to capture attention and disrupt ongoing cognition. Two underlying assumptions in this theoretical position are that the potency of affective stimuli transcends task boundaries (i.e., emotional distracters do not have to belong to a current task-set to disrupt processing and that there is an asymmetry between emotional and cognitive processing (i.e., emotional distracters disrupt cognitive processing, but not vice versa. These assumptions have remained largely untested, as common experimental probes of emotion-cognition interaction rarely manipulate task-relevance and only examine one side of the presumed asymmetry of interference. To test these propositions directly, a face-word Stroop protocol was adapted to independently manipulate (a the congruency between target and distracter stimulus features, (b the affective salience of distracter features, and (c the task-relevance of emotional compared to non-emotional target features. A three-way interaction revealed interdependent effects of distracter relevance, congruence, and affective salience. Compared to task-irrelevant distracters, task-relevant congruent distracters facilitated performance and task-relevant incongruent distracters impaired performance, but the latter effect depended on the nature of the target feature and task. Specifically, task-irrelevant emotional distracters resulted in equivalent performance costs as task-relevant non-emotional distracters, whereas task-irrelevant non-emotional distracters did not produce performance costs comparable to those generated by task-relevant emotional distracters. These results document asymmetric cross-task interference effects for affectively salient stimuli, supporting the notion of affective prioritization in human information processing.

  14. Affective processing in bilingual speakers: disembodied cognition?

    Pavlenko, Aneta

    2012-01-01

    A recent study by Keysar, Hayakawa, and An (2012) suggests that "thinking in a foreign language" may reduce decision biases because a foreign language provides a greater emotional distance than a native tongue. The possibility of such "disembodied" cognition is of great interest for theories of affect and cognition and for many other areas of psychological theory and practice, from clinical and forensic psychology to marketing, but first this claim needs to be properly evaluated. The purpose of this review is to examine the findings of clinical, introspective, cognitive, psychophysiological, and neuroimaging studies of affective processing in bilingual speakers in order to identify converging patterns of results, to evaluate the claim about "disembodied cognition," and to outline directions for future inquiry. The findings to date reveal two interrelated processing effects. First-language (L1) advantage refers to increased automaticity of affective processing in the L1 and heightened electrodermal reactivity to L1 emotion-laden words. Second-language (L2) advantage refers to decreased automaticity of affective processing in the L2, which reduces interference effects and lowers electrodermal reactivity to negative emotional stimuli. The differences in L1 and L2 affective processing suggest that in some bilingual speakers, in particular late bilinguals and foreign language users, respective languages may be differentially embodied, with the later learned language processed semantically but not affectively. This difference accounts for the reduction of framing biases in L2 processing in the study by Keysar et al. (2012). The follow-up discussion identifies the limits of the findings to date in terms of participant populations, levels of processing, and types of stimuli, puts forth alternative explanations of the documented effects, and articulates predictions to be tested in future research.

    2012-01-01

    Building cognitive abilities often requires sustained engagement with effortful tasks. We demonstrate that beliefs about willpower-whether willpower is viewed as a limited or non-limited resource-impact sustained learning on a strenuous mental task. As predicted, beliefs about willpower did not affect accuracy or improvement during the initial phases of learning; however, participants who were led to view willpower as non-limited showed greater sustained learning over the full duration of the task. These findings highlight the interactive nature of motivational and cognitive processes: motivational factors can substantially affect people's ability to recruit their cognitive resources to sustain learning over time.

    Lit, Lisa; Schweitzer, Julie B; Oberbauer, Anita M

    2011-05-01

    Our aim was to evaluate how human beliefs affect working dog outcomes in an applied environment. We asked whether beliefs of scent detection dog handlers affect team performance and evaluated relative importance of human versus dog influences on handlers' beliefs. Eighteen drug and/or explosive detection dog/handler teams each completed two sets of four brief search scenarios (conditions). Handlers were falsely told that two conditions contained a paper marking scent location (human influence). Two conditions contained decoy scents (food/toy) to encourage dog interest in a false location (dog influence). Conditions were (1) control; (2) paper marker; (3) decoy scent; and (4) paper marker at decoy scent. No conditions contained drug or explosive scent; any alerting response was incorrect. A repeated measures analysis of variance was used with search condition as the independent variable and number of alerts as the dependent variable. Additional nonparametric tests compared human and dog influence. There were 225 incorrect responses, with no differences in mean responses across conditions. Response patterns differed by condition. There were more correct (no alert responses) searches in conditions without markers. Within marked conditions, handlers reported that dogs alerted more at marked locations than other locations. Handlers' beliefs that scent was present potentiated handler identification of detection dog alerts. Human more than dog influences affected alert locations. This confirms that handler beliefs affect outcomes of scent detection dog deployments. PMID:21225441

    2015-11-01

    Following destruction or denervation of the primary visual cortex (V1) cortical blindness ensues. Affective blindsight refers to the uncanny ability of such patients to respond correctly, or above chance level, to visual emotional expressions presented to their blind fields. Fifteen years after its original discovery, affective blindsight still fascinates neuroscientists and philosophers alike, as it offers a unique window on the vestigial properties of our visual system that, though present in the intact brain, tend to be unnoticed or even actively inhibited by conscious processes. Here we review available studies on affective blindsight with the intent to clarify its functional properties, neural bases and theoretical implications. Evidence converges on the role of subcortical structures of old evolutionary origin such as the superior colliculus, the pulvinar and the amygdala in mediating affective blindsight and nonconscious perception of emotions. We conclude that approaching consciousness, and its absence, from the vantage point of emotion processing may uncover important relations between the two phenomena, as consciousness may have evolved as an evolutionary specialization to interact with others and become aware of their social and emotional expressions.

  7. Environmental issues affecting clean coal technology deployment

    Energy Technology Data Exchange (ETDEWEB)

    Miller, M.J. [Electric Power Research Inst., Palo Alto, CA (United States)

    1997-12-31

    The author outlines what he considers to be the key environmental issues affecting Clean Coal Technology (CCT) deployment both in the US and internationally. Since the international issues are difficult to characterize given different environmental drivers in various countries and regions, the primary focus of his remarks is on US deployment. However, he makes some general remarks, particularly regarding the environmental issues in developing vs. developed countries and how these issues may affect CCT deployment. Further, how environment affects deployment depends on which particular type of clean coal technology one is addressing. It is not the author`s intention to mention many specific technologies other than to use them for the purposes of example. He generally categorizes CCTs into four groups since environment is likely to affect deployment for each category somewhat differently. These four categories are: Precombustion technologies such as coal cleaning; Combustion technologies such as low NOx burners; Postcombustion technologies such as FGD systems and postcombustion NOx control; and New generation technologies such as gasification and fluidized bed combustion.

  17. Affective loop experiences: designing for interactional embodiment.

    Science.gov (United States)

    Höök, Kristina

    2009-12-12

    Involving our corporeal bodies in interaction can create strong affective experiences. Systems that both can be influenced by and influence users corporeally exhibit a use quality we name an affective loop experience. In an affective loop experience, (i) emotions are seen as processes, constructed in the interaction, starting from everyday bodily, cognitive or social experiences; (ii) the system responds in ways that pull the user into the interaction, touching upon end users' physical experiences; and (iii) throughout the interaction the user is an active, meaning-making individual choosing how to express themselves-the interpretation responsibility does not lie with the system. We have built several systems that attempt to create affective loop experiences with more or less successful results. For example, eMoto lets users send text messages between mobile phones, but in addition to text, the messages also have colourful and animated shapes in the background chosen through emotion-gestures with a sensor-enabled stylus pen. Affective Diary is a digital diary with which users can scribble their notes, but it also allows for bodily memorabilia to be recorded from body sensors mapping to users' movement and arousal and placed along a timeline. Users can see patterns in their bodily reactions and relate them to various events going on in their lives. The experiences of building and deploying these systems gave us insights into design requirements for addressing affective loop experiences, such as how to design for turn-taking between user and system, how to create for 'open' surfaces in the design that can carry users' own meaning-making processes, how to combine modalities to create for a 'unity' of expression, and the importance of mirroring user experience in familiar ways that touch upon their everyday social and corporeal experiences. But a more important lesson gained from deploying the systems is how emotion processes are co-constructed and experienced

  3. Thyroid Functions and Bipolar Affective Disorder

    Directory of Open Access Journals (Sweden)

    Subho Chakrabarti

    2011-01-01

    Full Text Available Accumulating evidence suggests that hypothalamo-pituitary-thyroid (HPT axis dysfunction is relevant to the pathophysiology and clinical course of bipolar affective disorder. Hypothyroidism, either overt or more commonly subclinical, appears to the commonest abnormality found in bipolar disorder. The prevalence of thyroid dysfunction is also likely to be greater among patients with rapid cycling and other refractory forms of the disorder. Lithium-treatment has potent antithyroid effects and can induce hypothyroidism or exacerbate a preexisting hypothyroid state. Even minor perturbations of the HPT axis may affect the outcome of bipolar disorder, necessitating careful monitoring of thyroid functions of patients on treatment. Supplementation with high dose thyroxine can be considered in some patients with treatment-refractory bipolar disorder. Neurotransmitter, neuroimaging, and genetic studies have begun to provide clues, which could lead to an improved understanding of the thyroid-bipolar disorder connection, and more optimal ways of managing this potentially disabling condition.

    Full Text Available Productivity in agriculture most relevantly and concisely expresses the economic efficiency of using the factors of production. Labour productivity is affected by a considerable number of variables (including the relationship system and interdependence between factors, which differ in each economic sector and influence it, giving rise to a series of technical, economic and organizational idiosyncrasies. The purpose of this paper is to analyse the underlying factors of the average work productivity in agriculture, forestry and fishing. The analysis will take into account the data concerning the economically active population and the gross added value in agriculture, forestry and fishing in Romania during 2008-2011. The distribution of the average work productivity per factors affecting it is conducted by means of the u-substitution method.

    2014-01-01

    This study assessed the relationships between recall of positive and negative events, API (attention to positive) and ANI (attention to negative information), and perception of happiness, with the hypothesis that recall affects the perception of happiness and that ANI and API affect recall. One hundred and five women filled in the APNI scale to assess API and ANI and were asked to listen to and recall a story presenting both positive and negative events, and provide an assessment of the character perceived happiness. Finally, they were asked to choose an ending for the story. Results showed that recall is related to the perception of happiness more than API and ANI, and that relationships occur among recall, API, ANI, and perception of happiness. A positive ending for the story was preferred. Discussion focuses on the implications of individual differences in paying attention to and recall positive and negative information.

  6. Human activities affecting trace gases and climate

    International Nuclear Information System (INIS)

    The Earth's climate has been in a constant state of change throughout geologic time due to natural perturbations in the global geobiosphere. However, various human activities have the potential to cause future global warming over a relatively short amount of time. These activities, which affect the Earth's climate by altering the concentrations of trace gases in the atmosphere, include energy consumption, particularly fossil-fuel consumption; industrial processes (production and use of chlorofluorocarbons, halons, and chlorocarbons, landfilling of wastes, and cement manufacture); changes in land use patterns, particularly deforestation and biomass burning; and agricultural practices (waste burning, fertilizer usage, rice production, and animal husbandry). Population growth is an important underlying factor affecting the level of growth in each activity. This paper describes how the human activities listed above contribute to atmospheric change, the current pattern of each activity, and how levels of each activity have changed since the early part of this century

    It is one thing that currently in China English learning persists through a student's whole study life, but it is another how long his persistence, an important factor in any language learning, can last. The factors affecting a student's persistence in this regard practically merits our attention. This paper traces and observes twenty students chosen by random. The research conducted here included their study motivation, academic excellence, psychological aspects relating to language learning and established corresponding models showing how these factors affect a student's persistence in his English learning. Although a small sample number was taken,of different students in China.the twenty students were typical of different students in China. The students' backgrounds were varied including both educational and environmental. Some suggestions are given indicating three separate but inter-related ways in how to further develop a student's persistence.

    International Nuclear Information System (INIS)

    Functional imaging of normal and dysfunctional emotional processes is an important tool for a better understanding of the pathophysiology of affective symptoms in schizophrenia patients. These symptoms are still poorly characterized with respect to their neural correlates. Comparisons of cerebral activation during emotional paradigms offered the possibility for a better characterization of cerebral dysfunctions during emotional processing in schizophrenia. Abnormal activation patterns reveal a complex dysfunctional subcortical-cortical network. This is modulated by respective genotypes as well as psycho- and pharmacotherapy. (orig.)

  2. Nutrients affecting brain composition and behavior

    Science.gov (United States)

    Wurtman, R. J.

    1987-01-01

    This review examines the changes in brain composition and in various brain functions, including behavior, that can follow the ingestion of particular foods or nutrients. It details those that are best understood: the increases in serotonin, catecholamine, or acetylcholine synthesis that can occur subsequent to food-induced increases in brain levels of tryptophan, tyrosine, or choline; it also discusses the various processes that must intervene between the mouth and the synapse, so to speak, in order for a nutrient to affect neurotransmission, and it speculates as to additional brain chemicals that may ultimately be found to be affected by changes in the availability of their nutrient precursors. Because the brain chemicals best known to be nutrient dependent overlap with those thought to underlie the actions of most of the drugs used to treat psychiatric diseases, knowledge of this dependence may help the psychiatrist to understand some of the pathologic processes occurring in his/her patients, particularly those with appetitive symptoms. At the very least, such knowledge should provide the psychiatrist with objective criteria for judging when to take seriously assertions that particular foods or nutrients do indeed affect behavior (e.g., in hyperactive children). If the food can be shown to alter neurotransmitter release, it may be behaviorally-active; however, if it lacks a discernible neurochemical effect, the likelihood that it really alters behavior is small.

These include the influence of heat ratings, kVp, waveform, exposure timer, filtration, focus-film distance, beam intensity distribution, x-ray tube age and focal spot size. Part three examines x-ray machine, equipment and patient factors which affect the dose received by individual patients. The factors considered include justification of examinations, choice of examination method, film/screen combinations, kVp, mAs, focus-film distance, collimation and field size, exposure time, projection, scatter, generator calibration errors, waveform, filtration, film processing and patient size. The patient dose implications of fluoroscopy systems, CT scanners, special procedures and mammography are also discussed. The report concludes with a brief discussion of patient dose levels in New Zealand and dose optimisation. 104 refs., 32 figs., 27 tabs

    Full Text Available Hunger, extreme desire to eat a certain food, taste, price, and convenience are among the main There are various factors that affect food preferences. Hunger, extreme desire to eat a certain food, taste, price, and convenience are among the main factors affecting food preferences. Additionally, general nutritional habits, family, friends, commercials, and availability of the food are also important for food preferences. Also, past experiences with foods are related to preferring or rejecting some foods. Socializing more with increasing age causes change in the food preferences of adolescents. Unhealthy nutrition habits form as a result of the adolescents consuming fast foods, spending time with their friends outside the house, and consuming more ready-made foods. Current developments in the food industry result in an increase in variety and consumption of snacks such as cookies, chocolate, chips, and crackers in adolescents. Considering all these, in this rewiev article, environmental and personal factors affecting food preferences have been investigated. (Jo­ur­nal of Cur­rent Pe­di­at­rics 2013; 11: 121-7

  5. Psychophysiological response patterns to affective film stimuli.

    Directory of Open Access Journals (Sweden)

    Marieke G N Bos

    Full Text Available Psychophysiological research on emotion utilizes various physiological response measures to index activation of the defense system. Here we tested 1 whether acoustic startle reflex (ASR, skin conductance response (SCR and heart rate (HR elicited by highly arousing stimuli specifically reflect a defensive state and 2 the relation between resting heart rate variability (HRV and affective responding. In a within-subject design, participants viewed film clips with a positive, negative and neutral content. In contrast to SCR and HR, we show that ASR differentiated between negative, neutral and positive states and can therefore be considered as a reliable index of activation of the defense system. Furthermore, resting HRV was associated with affect-modulated characteristics of ASR, but not with SCR or HR. Interestingly, individuals with low-HRV showed less differentiation in ASR between affective states. We discuss the important value of ASR in psychophysiological research on emotion and speculate on HRV as a potential biological marker for demarcating adaptive from maladaptive responding.

  6. Affective cognition: Exploring lay theories of emotion.

    2015-10-01

    Humans skillfully reason about others' emotions, a phenomenon we term affective cognition. Despite its importance, few formal, quantitative theories have described the mechanisms supporting this phenomenon. We propose that affective cognition involves applying domain-general reasoning processes to domain-specific content knowledge. Observers' knowledge about emotions is represented in rich and coherent lay theories, which comprise consistent relationships between situations, emotions, and behaviors. Observers utilize this knowledge in deciphering social agents' behavior and signals (e.g., facial expressions), in a manner similar to rational inference in other domains. We construct a computational model of a lay theory of emotion, drawing on tools from Bayesian statistics, and test this model across four experiments in which observers drew inferences about others' emotions in a simple gambling paradigm. This work makes two main contributions. First, the model accurately captures observers' flexible but consistent reasoning about the ways that events and others' emotional responses to those events relate to each other. Second, our work models the problem of emotional cue integration-reasoning about others' emotion from multiple emotional cues-as rational inference via Bayes' rule, and we show that this model tightly tracks human observers' empirical judgments. Our results reveal a deep structural relationship between affective cognition and other forms of inference, and suggest wide-ranging applications to basic psychological theory and psychiatry.

    Interpersonal impression formation is highly consequential for social interactions in private and public domains. These perceptions of others rely on different sources of information and processing mechanisms, all of which have been investigated in independent research fields. In social psychology, inferences about states and traits of others as well as activations of semantic categories and corresponding stereotypes have attracted great interest. On the other hand, research on emotion and reward demonstrated affective and motivational influences of social cues on the observer, which in turn modulate attention, categorization, evaluation, and decision processes. While inferential and categorical social processes have been shown to recruit a network of cortical brain regions associated with mentalizing and evaluation, the affective influence of social cues has been linked to subcortical areas that play a central role in detection of salient sensory input and reward processing. In order to extend existing integrative approaches to person perception, both the inferential-categorical processing of information about others, and affective and motivational influences of this information on the beholder should be taken into account.

    2014-03-01

    In response to mechanical loading skeletal muscle produces numerous growth factors and cytokines that enter the circulation. We hypothesized that myotubes produce soluble factors that affect osteoclast formation and aimed to identify which osteoclastogenesis-modulating factors are differentially produced by mechanically stimulated myotubes. C2C12 myotubes were subjected to mechanical loading by cyclic strain for 1 h, and postincubated with or without cyclic strain for 24 h. The effect of cyclic strain on gene expression in myotubes was determined by PCR. Conditioned medium (CM) was collected from cultures of unloaded and loaded myotubes and from MLO-Y4 osteocytes. CM was added to mouse bone marrow cells containing osteoclast precursors, and after 6 days osteoclasts were counted. Compared to unconditioned medium, CM from unloaded osteocytes increased osteoclast formation, while CM from unloaded myotubes decreased osteoclast formation. Cyclic strain strongly enhanced IL-6 expression in myotubes. CM from cyclically strained myotubes increased osteoclast formation compared to CM from unloaded myotubes, but this effect did not occur in the presence of an IL-6 antibody. In conclusion, mechanically loaded myotubes secrete soluble factors, among others IL-6, which affect osteoclast formation. These results suggest that muscle could potentially affect bone homeostasis in vivo via production of growth factors and/or cytokines. PMID:24264813

    The purpose of this paper is to present the results of research to identify, by satellite imagery, parameters of the environment affecting health on Earth. Thus, we suggest expanding the application of space technology to preventive medicine, as a new field in the peaceful uses of outer space. The scope of the study includes all parts of the environment, natural and man-made, and all kinds of protection of life: human, animal and vegetation health. The general objective is to consider and classify those factors, detectable from space, that affect or are relevant to health and may be found in the air, water, sea, soil, land, vegetation, as well as those linked to climate, industry, energy production, development works, irrigation systems, and human settlements. The special objective is the classification of environmental factors detectable from space, that are linked to communicable or chronic endemic diseases or health problems. The method of identifying the factors affecting health was the parallel study of environmental epidemiological and biological parameters. The role of environmental factors common to both human and animal populations is discussed. Conclusive findings are formulated and possible applications, both scientific and practical, in other sectors are also discussed.

  11. Cognitive determinants of affective forecasting errors

    2010-08-01

    Full Text Available Often to the detriment of human decision making, people are prone to an impact bias when making affective forecasts, overestimating the emotional consequences of future events. The cognitive processes underlying the impact bias, and methods for correcting it, have been debated and warrant further exploration. In the present investigation, we examined both individual differences and contextual variables associated with cognitive processing in affective forecasting for an election. Results showed that the perceived importance of the event and working memory capacity were both associated with an increased impact bias for some participants, whereas retrieval interference had no relationship with bias. Additionally, an experimental manipulation effectively reduced biased forecasts, particularly among participants who were most distracted thinking about peripheral life events. These findings have theoretical implications for understanding the impact bias, highlight the importance of individual differences in affective forecasting, and have ramifications for future decision making research. The possible functional role of the impact bias is discussed within the context of evolutionary psychology.

    2012-10-01

    Full Text Available Research on cognitive biases in depression has provided considerable evidence for the impact of emotion on cognition. Individuals with depression tend to preferentially process mood-congruent material and to show deficits in the processing of positive material leading to biases in attention, memory, and judgments. More research is needed, however, to fully understand which cognitive processes are affected. The current study further examines the impact of emotion on cognition using a priming design with facial expressions of emotion. Specifically, this study tested whether the presentation of facial expressions of emotion affects subsequent processing of affective material in participants with major depressive disorder (MDD and healthy controls (CTL. Facial expressions displaying happy, sad, angry, disgusted, or neutral expressions were presented as primes for 500ms, and participants’ speed to identify a subsequent target’s emotional expression was assessed. All participants displayed greater interference from emotional versus neutral primes, marked by slower response times to judge the emotion of the target face when it was preceded by an emotional prime. Importantly, the CTL group showed the strongest interference when happy emotional expressions served as primes whereas the MDD group failed to show this bias. These results add to a growing literature that shows that depression is associated with difficulties in the processing of positive material.

    Children whose parents or caregivers use drugs or alcohol are at increased risk of short- and long-term sequelae ranging from medical problems to psychosocial and behavioral challenges. In the course of providing health care services to children, pediatricians are likely to encounter families affected by parental substance use and are in a unique position to intervene. Therefore, pediatricians need to know how to assess a child's risk in the context of a parent's substance use. The purposes of this clinical report are to review some of the short-term effects of maternal substance use during pregnancy and long-term implications of fetal exposure; describe typical medical, psychiatric, and behavioral symptoms of children and adolescents in families affected by substance use; and suggest proficiencies for pediatricians involved in the care of children and adolescents of families affected by substance use, including screening families, mandated reporting requirements, and directing families to community, regional, and state resources that can address needs and problems.

  15. On a disturbance of affectivity in schizophrenic adolescents: implications for affect theory.

    Science.gov (United States)

    Siomopoulos, G

    1980-01-01

    As recently as 1969 Loeb stated, "Not only has adolescent schizophrenia been largely ignored by the clinician and research worker but until recent years the entire subject of adolescence had received scant attention" (p. 462). Since that time, a number of investigators have attended to similarities and differences between the schizophrenic syndrome, as a whole, and schizophrenia as it appears in adolescence. One of the findings that has been alluded to by some authors concerns the notion that affect is less severely disturbed, especially in the dimension of affective responsiveness, in adolescent schizophrenics (Sands, 1956). Observations by the author and others suggest that greater attention be paid to the variety of affectivity to delineate this area of symptomatology, which both Kraepelin and Bleuler considered so fundamental and typical in their designations of dementia praecox and schizophrenia. Indeed the purpose of this study concerns the description and dynamic understanding of a typical disturbance of affectivity in adolescent schizophrenics. This disturbance is characterized by a quality of affective communication in which the patient relates to the people around him in a superficial, socially acceptable, receptionist-like manner which induces in the observer the impression that the individual's genuine feelings are not prominent. For want of a better term, we may designate this affective state "airline-hostess affectivity" (A.H.A.). The disturbance is not exclusive to adolescent schizophrenics but can also be observed in young adults too before a phase of chronic adaptation to the schizophrenic process. PMID:7369002

    2015-10-01

    Affect integration was operationalized through the Affect Consciousness (AC) construct as degrees of awareness, tolerance, nonverbal expression and conceptual expression of 11 affects. These aspects are assessed through a semi-structured Affect Consciousness Interview (ACI) and separate rating scales (Affect Consciousness Scales (ACSs)) developed for use in research and clinical work with adults with psychopathological disorders. Age-adjusted changes were made in the interview and rating system. This study explored the applicability of the adjusted ACI to a sample of 11-year-old children with internalizing problems through examining inter-rater reliability of the adjusted ACI, along with relationships between the AC aspects and aspects of mental health as symptoms of depression, symptoms of anxiety, social competence, besides general intelligence. Satisfactory inter-rater reliability was found, as well as consistent relationships between the AC aspects and the various aspects of mental health, a finding which coincides with previous research. The finding indicates that the attainment of the capacity to deal adaptively with affect is probably an important contributor to the development of adequate social competence and maybe in the prevention of psychopathology in children. The results indicate that the adjusted ACI and rating scales are useful tools in treatment planning with children at least from the age of 11 years. PMID:24941941

The erythrocytes were in the channels delimitated by collagenous and elastic bundles and arachnoid cells, showing their tortuous and intercommunicating row from the pedicle to the fibrous capsule. The core portion of the pedicle and the center represented a principal route to the bulk outflow of cerebrospinal fluid and erythrocytes. In the severe hemorrhage, the fibrocellular components are desorganized, increasing the extracellular channels. We could see arachnoid granulations without erythrocytes, which cells showed big round nucleous suggesting their transformation into phagocytic cells.

    Full Text Available The objective of this study was to present some factors affecting feed efficiency in dairy goats. To develop our work, individual and average data from performance experiments with lactating goats were used. The following variables were evaluated: gross feed efficiency, adjusted feed efficiency, dry matter intake, milk-yield, 3.5% fat-corrected milk yield, dry matter digestibility, dietary neutral detergent fiber content, different roughage-to-concentrate ratios and body weight. The statistical analyses involved the application of descriptive and dispersion measures besides Pearson's correlation coefficient and linear regression analysis. The analyzed variables were highly correlated with feed efficiency. The feed efficiency of lactating goats was affected by the milk fat correction, dry matter digestibility, dietary fiber content, proportion of roughage in the diet and body weight. Among these factors, standardization of the milk fat appeared to be the most efficient in correcting the feed efficiency in lactating goats. Correction of some of these factors implies greater precision in the measurement of feed efficiency.

    Full Text Available This study aimed to examine key factors affecting rural female facilitators’ role in participatory rural developmentin Tehran Province. Since the researchers intended to have abetter insight into the facilitators’ role and employ inquiry as alearning forum for bringing about changes for all participants,they preferred to use a case study based upon an appreciativeinquiry method. The study divided the factors affecting thefacilitators’ role into two main categories: driving factors andpreventing factors. The former are: two-way communication,election of rural eligible facilitators, participation, sense ofresponsibility, and the latter are: cultural and tribal fanaticism,lack of permanent female extension workers and frequentmanagement changes. Appreciative inquiry as a positive modeof action research could facilitate the process of education andcommunication for all stakeholders. We suggested that thereshould be a shift from the extension as a knowledge transfer tofacilitation as people’s own knowledge creation. This studyshowed that appreciative inquiry could facilitate the process ofchange and gender-awareness. This research method couldalso facilitate mutual communication between the rural facilitatorsand extension workers.

  15. How Experimental Trial Context Affects Perceptual Categorization

    Directory of Open Access Journals (Sweden)

    Thomas J Palmeri

    2015-02-01

    Full Text Available To understand object categorization, participants are tested in experiments often quite different from how people experience object categories in the real world. Learning and knowledge of categories is measured in discrete experimental trials, those trials may or may not provide feedback, trials appear one after another, after some fixed inter-trial interval, with hundreds of trials in a row, within experimental blocks with some structure dictated by the experimental design. In the real world, outside of certain educational and vocational contexts, opportunities to learn and use categories are intermixed over time with a whole multitude of intervening experiences. It is clear from any elementary understanding of human cognition that sequential effects matter, yet this understanding is often ignored, and categorization trials are often instead treated as independent events, immune to local trial context. In this perspective, we use some of our work to illustrate some of the consequences of the fact that categorization experiments have a particular trial structure. Experimental trial context can affect performance in category learning and categorization experiments in ways that can profoundly affect theoretical conclusions.

    2014-01-01

    Human freezing has been objectively assessed using a passive picture viewing paradigm as an analog for threat. These results should be replicated for other stimuli in order to determine their stability and generalizability. Affective films are used frequently to elicit affective responses, but it is unknown whether they also elicit freezing-like defense responses. To test whether this is the case, 50 participants watched neutral, pleasant and unpleasant film fragments while standing on a stabilometric platform and wearing a polar band to assess heart rate. Freezing-like responses (indicated by overall reduced body sway and heart rate deceleration) were observed for the unpleasant film only. The unpleasant film also elicited early reduced body sway (1-2 s after stimulus onset). Heart rate and body sway were correlated during the unpleasant film only. The results suggest that ecologically valid stimuli like films are adequate stimuli in evoking defense responses. The results also underscore the importance of including time courses in human experimental research on defense reactions in order to delineate different stages in the defense response. PMID:23805855

  17. Rubber hand illusion affects joint angle perception.

    Directory of Open Access Journals (Sweden)

    Martin V Butz

    Full Text Available The Rubber Hand Illusion (RHI is a well-established experimental paradigm. It has been shown that the RHI can affect hand location estimates, arm and hand motion towards goals, the subjective visual appearance of the own hand, and the feeling of body ownership. Several studies also indicate that the peri-hand space is partially remapped around the rubber hand. Nonetheless, the question remains if and to what extent the RHI can affect the perception of other body parts. In this study we ask if the RHI can alter the perception of the elbow joint. Participants had to adjust an angular representation on a screen according to their proprioceptive perception of their own elbow joint angle. The results show that the RHI does indeed alter the elbow joint estimation, increasing the agreement with the position and orientation of the artificial hand. Thus, the results show that the brain does not only adjust the perception of the hand in body-relative space, but it also modifies the perception of other body parts. In conclusion, we propose that the brain continuously strives to maintain a consistent internal body image and that this image can be influenced by the available sensory information sources, which are mediated and mapped onto each other by means of a postural, kinematic body model.

    Makvand Hosseini, Sh.; Azad Fallah, P.; Rasoolzadeh Tabatabaei, S. K.; Ghannadyan Ladani, S. H.; Heise, C.

    We studied the patterns of activation over the cerebral cortex in reaction to affective film stimuli in four groups of extroverts, introverts, neurotics and emotionally stables. Measures of extraversion and neuroticism were collected and resting EEG was recorded from 40 right handed undergraduate female students (19-23) on one occasion for five 30s periods in baseline condition and in affective states. Mean log-transformed absolute alpha power was extracted from 12 electrode sites and analyzed. Patterns of activation were different in personality groups. Different patterns of asymmetries were observed in personality groups in reaction to affective stimuli. Results were partly consistent with approach and withdrawal model and provided supportive evidence for the role of right frontal asymmetry in negative affects in two groups (introverts and emotionally stables) as well as the role of right central asymmetry (increase on right and decrease on left) in active affective states (anxiety and happiness) in all personality groups. Results were also emphasized on the role of decrease activity relative to baseline in cortical regions (bilaterally in frontal and unilaterally in left parietal and temporal regions) in moderating of positive and negative emotion.

    Moini, Hamid; Turcan, Romeo V.; Gulieva, Valeria

    This study explores whether student nationality affect their thesis writing by examining the difference between domestic and international students in Aalborg University. Responses were obtained from one hundred and twenty six bachelor and master studies – taught in English and Danish – from the...... Department of Business and Management. A two-stage data analysis was performed. In the first stage, data was analyzed using a one-way analysis of variance. This sheds light on the students’ decision to write a thesis in order to complete their program. In the second stage, a step-wise discriminant analysis...... was performed in an attempt to distinguish between the two groups of students in terms of multiple characteristics. Overall, it emerges that the variety of quantitative sampling, gender, and the research methodology are the key factors discriminating between the two groups of students....

  20. The marketing implications of affective product design.

    Emotions are compelling human experiences and product designers can take advantage of this by conceptualizing emotion-engendering products that sell well in the market. This study hypothesized that product attributes influence users' emotions and that the relationship is moderated by the adherence of these product attributes to purchase criteria. It was further hypothesized that the emotional experience of the user influences purchase intention. A laboratory study was conducted to validate the hypotheses using mobile phones as test products. Sixty-two participants were asked to assess eight phones from a display of 10 phones and indicate their emotional experiences after assessment. Results suggest that some product attributes can cause intense emotional experience. The attributes relate to the phone's dimensions and the relationship between these dimensions. The study validated the notion of integrating affect in designing products that convey users' personalities. PMID:17303064

    2015-02-01

    The myxosporean parasite Kudoa septempunctata has been isolated from cultured olive flounder (Paralichthys olivaceus) and was recently identified as a cause of food poisoning in humans. Since the sporoplasm plays an important role in causing diarrhea by invading intestinal cells, the specific factors affecting the release of sporoplasm from spores should be determined. Thus, we investigated the effect of digestive and serum enzymes, fetal bovine serum (FBS), temperature, and the role of glucose in cell culture media on the release of sporoplasm. Sporoplasm release was observed in the groups treated with FBS and media containing glucose. In addition, 1,10-phenanthroline inhibited the release of sporoplasm in the FBS medium. These results indicate that K. septempunctata uses glucose for releasing its sporoplasm and that zinc or metalloprotease is related to the release mechanism. The present study provides important information for the development of agents to prevent sporoplasm release and the consequent food poisoning caused by K. septempunctata. PMID:25563617

    On the basis of analyzed clinical material several observations were attempted which were related to the patients' awareness of one's own affective psychosis. It was discovered that patients with endogenous depression considered themselves to be ill, but only in relation to depression. They usually do not perceive in themselves any psychotic illness. It was noticed that in depression past achievements appeared to be foreign to the patients. This was described in among other terms as "emotionally empty judgments". Analyzing the clinical picture of hypomanic states, stress was placed on the notion of the coexistence of logical thinking (and in some cases these thinking patterns are concerned with a feeling of heightened cognitive ability) with thinking styles based on logical errors. In all patients hypermnesia appears more important than other factors. The above mentioned phenomena are the subject of further research. PMID:1301600

    Full Text Available How to enhance customer satisfaction and technology innovation have been topics of discussion for some time; however, few studies have explored the two issues by applying the knowledge creation theory, and analyzed their differences in knowledge creation activities. The present study aims to explore how the firm’s organizational goal affects its knowledge creation process. Based on Nonaka’s knowledge creation theory, questionnaires were developed and sent to Taiwanese firms in various industries, including the manufacturing and service industries. These questionnaires were collected either by mail or interview. Our findings suggest that externalization and combination activities should be emphasized when the organizational goal is innovation, whereas internalization activity should be emphasized when the organizational goal is customer satisfaction.

    BACKGROUND: Chronic sleep deprivation combined with work during the night is known to affect performance and compromise residents' own safety. The aim of this study was to examine markers of circadian rhythm and the sleep-wake cycle in surgeons working night shifts. METHODS: Surgeons were monitored...... prospectively for 4 days: pre call, on call, post call day 1 (PC1), and post call day 2 (PC2). The urinary metabolite of melatonin and cortisol in saliva were measured to assess the circadian rhythm. Sleep and activity were measured by actigraphy. Subjective measures were assessed by the Karolinska Sleepiness...... Scale and Visual Analog Scale of fatigue, general well-being, and sleep quality. RESULTS: For both metabolite of melatonin and cortisol, a significant difference (P < .05) was found in the measurement period between on call and pre call values. There was increased sleep time during the day on call and...

  7. Analysis of parameters affecting beam gauge performance

    2000-01-01

    Beam gauges have been used in the last decade or so for measuring the internal azimuthal compressive coil stresses in superconducting magnets. In early model Large Hadron Collider Interaction Region (LHC IR) quadrupoles tested at Fermilab, the beam gauges indicated excessively high amounts of inner and outer coil prestress during the collaring process, inconsistent with the coil size and modulus data. In response to these measurements, a simple mechanics based quantitative understanding of different factors affecting beam gauges has been developed. A finite element model with contact elements and non-linear material behavior, confirmed with experimental results, was developed. The results indicate that a small plastic deformation of either the beam or the backing plate can cause significant errors in the measured stress values. The effect of variations in coil modulus and support boundary conditions on beam gauge performance are also discussed. (3 refs).

  9. Factors affecting passive monitoring of radon

    International Nuclear Information System (INIS)

    In recent years, increasing cancer has been expressed as a possible health hazards associated with long-term exposures to a large population at a low level of radon in the environment. Because radon is ubiquitous nuclide, nation-wide monitoring is necessary to determine lung cancer risk. For such purpose, passive sampling methods with track etch detector or charcoal adsorption collector may have the advantage in lower cost and convenience. The charcoal adsorption collector is considered in this study. Various factors may significantly affect the charcoal adsorption mechanism on its practical application. Moisture effects are discussed here as having major impact on radon collection by charcoal. Set of equations are presented in this report to describe adsorption of radon including moisture effects.

    Full Text Available Abstract Members of the synthetic biology community have discussed the significance of word selection when describing synthetic biology to the general public. In particular, many leaders proposed the word "create" was laden with negative connotations. We found that word choice and framing does affect public perception of synthetic biology. In a controlled experiment, participants perceived synthetic biology more negatively when "create" was used to describe the field compared to "construct" (p = 0.008. Contrary to popular opinion among synthetic biologists, however, low religiosity individuals were more influenced negatively by the framing manipulation than high religiosity people. Our results suggest that synthetic biologists directly influence public perception of their field through avoidance of the word "create".

  11. Affecting the value chain through supplier kaizen.

    Forman, C R; Vargas, D H

    1999-02-01

    In the aerospace industry, typically 60 percent of a product's cost and 70 percent of the lead time are due to purchased material. To affect price and customer responsiveness, improvement initiatives must be extended into the supply chain. Many companies have developed supply base management systems that include long-term agreements with suppliers, partnering with suppliers in risk taking and product design, information sharing, and quality and delivery rating systems. The premise is that suppliers are an extension of the factory. But to take full advantage of customer-supplier relationships, the suppliers must be "developed" in the same manner as a manufacturing unit. Supplier kaizen is a method of bringing suppliers to the same level of operations as the parent company, through training and improvement projects, to ensure superior performance and nurture the trust that is required for strong partnerships. This article describes Sikorsky Aircraft's use of kaizen to improve its supply base management. PMID:10345628

  12. The neurobiology of pain, affect and hypnosis.

    Feldman, Jeffrey B

    2004-01-01

    Recent neuroimaging studies have used hypnotic suggestion to distinguish the brain structures most associated with the sensory and affective dimensions of pain. This paper reviews studies that delineate the overlapping brain circuits involved in the processing of pain and emotions, and their relationship to autonomic arousal. Also examined are the replicated findings of reliable changes in the activation of specific brain structures and the deactivation of others associated with the induction of hypnosis. These differ from those parts of the brain involved in response to hypnotic suggestions. It is proposed that the activation of a portion of the prefrontal cortex in response to both hypnotic suggestions for decreased pain and to positive emotional experience might indicate a more general underlying mechanism. Great potential exists for further research to clarify the relationships among individual differences in reactivity to pain, emotion, and stress, and the possible role of such differences in the development of chronic pain.

    Full Text Available 2009 was one of the hardest years in the last decades for SMEs. The areas that had faced difficulties before the crisis felt sharply the negative effects, but those which had registered continuous progress until the crisis broke out have also been affected. 2010 was a year of reconsolidation, while the current year could mark off a progress for most SMEs, due to a very special evolution of the German economy as a whole (an economic growth of 3.6% in 2010, much more over analyst expectations, and a forecast of 2.8% for 2011. Regarding the establishment of SMEs in the crisis period, an unexpected development has paradoxically been noticed in Germany: the interest of individuals in establishing a business, declining in the last years, began to grow.

  14. Homocysteine thiolactone affects protein ubiquitination in yeast.

    Bretes, Ewa; Zimny, Jarosław

    2013-01-01

    The formation of homocysteine thiolactone (HcyTl) from homocysteine occurs in all examined so far organisms including bacteria, yeast, and humans. Protein N-homocysteinylation at the ε-amino group of lysine is an adverse result of HcyTl accumulation. Since tagging of proteins by ubiquitination before their proteasomal degradation takes place at the same residue, we wondered how N-homocysteinylation may affect the ubiquitination of proteins. We used different yeast strains carrying mutations in genes involved in the homocysteine metabolism. We found positive correlation between the concentration of endogenous HcyTl and the concentration of ubiquitinated proteins. This suggests that N-homocysteinylation of proteins apparently does not preclude but rather promotes their decomposition. PMID:24051443

    2011-01-01

    Full Text Available In an era of spiraling health care costs and limited resources, policy makers and health care payers are concerned about the cost effectiveness of antibiotics. The aim of this study is to draw on published economic evaluations with a view to identify and illustrate the factors affecting the cost effectiveness of antibiotic treatment of bacterial infections. The findings indicate that the cost effectiveness of antibiotics is influenced by factors relating to the characteristics and the use of antibiotics (i.e., diagnosis, comparative costs and comparative effectiveness, resistance, patient compliance with treatment, and treatment failure and by external factors (i.e., funding source, clinical pharmacy interventions, and guideline implementation interventions. Physicians need to take into account these factors when prescribing an antibiotic and assess whether a specific antibiotic treatment adds sufficient value to justify its costs.

  18. Colour-grapheme synaesthesia affects binocular vision

    Directory of Open Access Journals (Sweden)

    Chris L.E. Paffen

    2011-11-01

    Full Text Available In colour-grapheme synaesthesia, non-coloured graphemes are perceived as being inherently coloured. In recent years, it has become evident that synaesthesia-inducing graphemes can affect visual processing in a manner comparable to real, physical colours. Here, we exploit the phenomenon of binocular rivalry in which incompatible images presented dichoptically compete for conscious expression. Importantly, the competition only arises if the two images are sufficiently different; if the difference between the images is small, the images will fuse into a single mixed percept. We show that achromatic graphemes that induce synaesthetic colour percepts evoke binocular rivalry, while without the synaesthetic percept, they do not. That is, compared to achromatically perceived graphemes, synaesthesia-inducing graphemes increase the predominance of binocular rivalry over binocular fusion. This finding shows that the synaesthetic colour experience can provide the conditions for evoking binocular rivalry, much like stimulus features that induce rivalry in normal vision.

    The aim of the study was to investigate how temperament affects learning ability in calves. Nine two-month-old Holstein-Friesian bull calves were subjected to four challenge tests: novel object (NOT), novel environment (NET), social isolation (SIT), and social isolation with a novel environmental...... cue (SI/E). During these tests, hypothesised temperament variables were recorded. Hypothesised learning variables were recorded during training on an operant task. Principal component analysis (PCA) was conducted on temperament variables and learning variables separately. Principal components (PCs...... variables, and these were proposed to reflect fearfulness, activity, exploration, and attention towards the environment. These hypothesised underlying temperamental traits were consistent with findings of previous studies using larger numbers of calves. Two learning PCs were extracted from the PCA on...

  20. Small agricultural impoundments affect pollutant transport

    Science.gov (United States)

    Balcerak, Ernie

    2013-03-01

    Reservoirs created by dams intercept runoff from upslope areas and thus are often sinks for fertilizers and other pollutants that would otherwise flow downstream. Most studies of solute transport through impoundments have focused on large, long-lived systems. However, small impoundments, such as those created for irrigation or livestock watering, are common in agricultural regions, and their total global surface area is comparable to that of large reservoirs. As these small systems mature, the impoundments fill with sediment, creating ecosystems with wetland-like characteristics. Because dams that create these small impoundments are more likely to be degraded, poorly maintained, or removed by their owners, it is important to understand how changes in such systems may affect pollutant transport.

    2016-01-01

    Epigenetic mechanisms are able to regulate plant development by generating non-Mendelian allelic interactions. An example of these are the responses to environmenal stimuli that result in phenotypic variability and transgression amongst important crop traits. The need to predict phenotypes from genotypes to understand the molecular basis of the genotype-by-environment interaction is a research priority. Today, with the recent discoveries in the field of epigenetics, this challenge goes beyond analyzing how DNA sequences change. Here we review examples of epigenetic regulation of genes involved in carotenoid synthesis and degradation, cases in which histone- and/or DNA-methylation, and RNA silencing at the posttranscriptional level affect carotenoids in plants.

  2. The radiotherapy affects the cognitive processes

    International Nuclear Information System (INIS)

    Researchers from the medical center of the free university of Amsterdam report that the radiotherapy can hinder the cognitive functions of patients affected by cerebral tumors treated after a surgery. Even low dose radiation could contribute in their opinion, to the progressive cognitive decline of patients suffering of low grade gliomas, the most commune cerebral tumor. To get these conclusions, 65 patients, whom half of them received a radiotherapy, had a neurological and psychological evaluation twelve years after their treatment. Results: 53% of patients treated by radiotherapy present disorders of attention, memory, execution and speed of information treatment against 27% of these ones that received an only surgery. The researchers conclude to the necessity to take into account this risk in the choice of treatment, or even to avoid radiotherapy in this precise case. (N.C.)

    1989-01-01

    The factors affecting particle size of reactive microgels formed during the self-emulsifying copolymerization of unsaturated polyester (UP )with butyl acrylate (BA)have been studied. The parameters discussed are: the proportion of the UP in the monomer mixture, the molecular weight and the carboxyl value of the UP, the phase ratio, the electrolyte concentration and the polar solvent additive. The seeding emulsion polymerization is discussed as well. It turned out that the particle size of the reactive microgels can be controlled in a definite range by changing the experimental conditions. However the particle size distribution becomes broader as the average diameter increases. It is suggested that the agglomeration of primary particles plays an important role during the growth of microgel particle.

  4. Affective disorders among women during post partum

    2004-08-01

    Full Text Available Women, in general, present a high rate of prevalence of affective disorders, mainly depressive ones, during their lives. This is even more evident during their puerperal time, were depression is quite common. This is, probably, due to the fact of a highest physical and emotional needs during this difficult period, for both the mother and the family,as well. This clinical condition will increase both the mobility and mortality rates among puerperal women and will increase the risk for new episodes of depression on future pregnancies. Since we all know that during puerperium, both mother and child are usually attended by the Health System, this is a good time to detect these disorders. Therefore, we will try to review the pertinent medical literature regarding this probem, in order to provide the psychiatrist and another physicians with new, effective tools, that will allow them to recognize earlier, patients with this disorder, handle them properly to avoid all negative consequences.

  5. Issues affecting the acceptance of hydrogen fuel

    International Nuclear Information System (INIS)

    While the topic of hydrogen as an alternative vehicle fuel is gaining increasing attention internationally, one significant aspect of its introduction has been given less attention than others: the public acceptance of such a new technology and fuel. After reviewing the existing literature on acceptance, risk perception and customer satisfaction, this paper describes the development of a model that illustrates important aspects in influencing a person's attitude towards a new product. 'Values', 'wants' and 'perception' are the three components found to influence acceptance, they themselves are affected by 'social background' and 'experience'. Suggestions are then given on how to use marketing methods, education projects and product exposure in order to maximise the likelihood of a successful introduction of hydrogen as an alternative fuel.

    2012-11-01

    ABSTRACT Since 1995, lettuce in coastal California, where more than half of the crop in North America is grown, has consistently suffered from severe outbreaks of Verticillium wilt. The disease is confined to this region, although the pathogen (Verticillium dahliae) and the host are present in other crop production regions in California. Migration of the pathogen with infested spinach seed was previously documented, but the geographic sources of the pathogen, as well as the impact of lettuce seed sparsely infested with V. dahliae produced outside coastal California on the pathogen population in coastal California remain unclear. Population analyses of V. dahliae were completed using 16 microsatellite markers on isolates from lettuce plants in coastal California, infested lettuce seed produced in the neighboring Santa Clara Valley of California, and spinach seed produced in four major spinach seed production regions: Chile, Denmark, the Netherlands, and the United States (Washington State). California produces 80% of spinach in the United States and all seed planted with the majority infested by V. dahliae comes from the above four sources. Three globally distributed genetic populations were identified, indicating sustained migration among these distinct geographic regions with multiple spinach crops produced each year and repeated every year in coastal California. The population structure of V. dahliae from coastal California lettuce plants was heavily influenced by migration from spinach seed imported from Denmark and Washington. Conversely, the sparsely infested lettuce seed had limited or no contribution to the Verticillium wilt epidemic in coastal California. The global trade in plant and seed material is likely contributing to sustained shifts in the population structure of V. dahliae, affecting the equilibrium of native populations, and likely affecting disease epidemiology.

  7. Ethical and affective evaluation of environmental risks

    International Nuclear Information System (INIS)

    Full text of publication follows: the present paper will be concerned with environmental risk perception, with special emphasis on those environmental risks that pertain to global change phenomena, such as climate change and ozone depletion. Two determinants of risk judgments are investigated that seem particularly relevant to environmental risks: ethical and affective evaluations. It is assumed that the focus of risk evaluation can be on one of two aspects: a) on an evaluation of potential losses, or b) on ethical considerations. We assume that both, potential loss and violation of ethical principles elicit emotional evaluations, but that these two judgmental aspects are associated with different specific emotions. Following cognitive emotion theories, we distinguish loss-based emotions, such as worry and fear, from ethical emotions, e.g., guilt and anger. A study is presented that investigates the role of ethical and affective evaluations in risk judgments. Various environmental risks were presented to subjects, e.g., air pollution, ozone depletion, climate change and destruction of ecological balance. For each environmental risk, subjects indicated in free-response format as well as on rating scales the extent to which ethical principles were violated, and the intensity of both loss-based and ethical emotions. The correlational structure of the emotion ratings confirms the distinction between loss-based and ethical emotions. Risk judgments co-vary with the strength of ethical evaluation and with the intensity of loss-based emotions, but are independent of ethical emotions. The implications of these findings for the risk appraisal process are discussed. (authors)

  8. Ectomycorrhizal activity as affected by soil liming

    Energy Technology Data Exchange (ETDEWEB)

    Andersson, Solbritt

    1996-05-01

    Acidification of the forest soils in southern Sweden due to atmospheric deposition has become evident during recent decades. To counteract further acidification, liming of forests in the most affected areas has been proposed. Most forest trees in the temperate and boreal forest ecosystems live in symbiosis with ectomycorrhizal fungi, and their uptake of mineral nutrients from the soil is greatly influenced by the symbiosis. In this thesis effects of liming on ectomycorrhiza have been studied in relation to effects on root colonization, fungal growth and nitrogen uptake. In field experiments the effects of liming on ectomycorrhizal colonization of root tips were variable, possibly due to different soil types and climatic variations. However, a changed mycorrhizal community structure could be detected. Laboratory studies also showed that the substrate may influence the outcome of lime applications; the nutrient status of the substrate had a marked effect on how mycelial growth was affected by liming. Under the experimental conditions used in the studies presented in this thesis, liming reduced the uptake of nitrogen and phosphorus by both mycorrhizal and non-mycorrhizal plants. The amount of extractable nitrogen and phosphorus in the peat was also reduced by liming. The latter could be due to either microbial or chemical immobilization. The lime induced decrease in nitrogen uptake was stronger in non-mycorrhizal plants than in mycorrhizal plants. Thus, the mycorrhizal plants had a higher ability to deal with the negative effects of liming on nitrogen availability. This was not the case for phosphorus. The lime induced decrease in phosphorus uptake was stronger for mycorrhizal plants, and in the highest lime treatment there was no significant difference between the mycorrhizal and the non-mycorrhizal spruce plants. 76 refs, 2 figs, 1 tab

    The present study investigated whether and how facial attractiveness affects sustained attention. We adopted a multiple-identity tracking paradigm, using attractive and unattractive faces as stimuli. Participants were required to track moving target faces amid distractor faces and report the final location of each target. In Experiment 1, the attractive and unattractive faces differed in both the low-level properties (i.e., luminance, contrast, and color saturation) and high-level properties (i.e., physical beauty and age). The results showed that the attractiveness of both the target and distractor faces affected the tracking performance: The attractive target faces were tracked better than the unattractive target faces; when the targets and distractors were both unattractive male faces, the tracking performance was poorer than when they were of different attractiveness. In Experiment 2, the low-level properties of the facial images were equalized. The results showed that the attractive target faces were still tracked better than unattractive targets while the effects related to distractor attractiveness ceased to exist. Taken together, the results indicate that during attentional tracking the high-level properties related to the attractiveness of the target faces can be automatically processed, and then they can facilitate the sustained attention on the attractive targets, either with or without the supplement of low-level properties. On the other hand, only low-level properties of the distractor faces can be processed. When the distractors share similar low-level properties with the targets, they can be grouped together, so that it would be more difficult to sustain attention on the individual targets.

  10. Do landscape factors affect brownfield carabid assemblages?

    International Nuclear Information System (INIS)

    The carabid fauna of 28 derelict sites in the West Midlands (England) were sampled over the course of one growing season (April-October, 1999). The study aimed to investigate the relationship between carabid assemblages and five measures of landscape structure pertinent to derelict habitat. At each site measurements of landscape features pertinent to derelict habitat were made: (i) the proximity of habitat corridors; (ii) the density of surrounding derelict land; (iii) the distance between the site and the rural fringe; and (iv) the size of the site. Concurrent surveys of the soil characteristics, vegetation type, and land use history were conducted. The data were analysed using a combination of ordination (DCA, RDA), variance partitioning (using pRDA) and binary linear regression. The results suggest that:1.There is very little evidence that the carabid assemblages of derelict sites were affected by landscape structure, with assemblages instead being principally related to within-site habitat variables, such as site age (since last disturbance), substrate type and vegetation community. 2.No evidence was found to support the hypothesis that sites away from railway corridors are more impoverished in their carabid fauna than sites on corridors. 3.There are some suggestions from this study that rarer and non-flying specialist species may be affected by isolation, taking longer to reach sites. We infer from this that older sites with retarded succession, and sites in higher densities of surrounding derelict land may eventually become more species rich and that these sites may be important for maintaining populations of rarer and flightless species. 4.Conservation efforts to maintain populations of these species should focus principally on habitat quality issues, such as maintaining early successional habitats that have a diversity of seed producing annuals and perennial plants and enhancing substrate variability rather than landscape issues

    Metaphor is examined in the very different iscourse contexts of the classroom and of reconciliation talk to highlight the neglected affective dimension. The distribution of metaphors across discourse shows clustering at certain points, often where speakers are engaged in critical interpersonal discourse activity. Clusters in classroom talk co-occur with sequences of agenda management where teachers prepare students for upcoming lessons and with giving feedback to students, both of which require careful management of interpersonal and affective issues. Clusters in reconciliation talk co-occur with discourse management and with two situations with significant affective dynamics: appropriation of metaphor and exploration of alternative scenarios.

    How should affect be appropriately annotated and how should machine learning best be employed to map manifestations of affect to affect annotations? What is the use of ratings of affect for the study of affective computing and how should we treat them? These are the key questions this paper...... attempts to address by investigating the impact of dissimilar representations of annotated affect on the efficacy of affect modelling. In particular, we compare several different binary-class and pairwise preference representations for automatically learning from ratings of affect. The representations are...... attributes, respectively; these attributes are coupled with ratings of various affective and cognitive states. The main results of the paper suggest that ratings (when used) should be naturally transformed to ordinal (ranked) representations for obtaining more reliable and generalisable models of affect.

    A comprehensive climatology of migratory anticyclones affecting the Mediterranean was generated by the University of Melbourne finding and tracking algorithm (MS algorithm), applied to 34 years (1979-2012) of ERA-Interim MSLP on a 1.5°x1.5° resolution. The algorithm was employed for the first time for anticyclones in this region, thus, its robustness and reliability in efficiently capturing the individual characteristics of the anticyclonic tracks in such a closed basin with complex topography were checked and verified. Then, the tracks and the statistical properties of the migratory systems were calculated and analyzed. Considering that cold-core anticyclones are shallow and weaken with height contrary to the warm-core that exhibit a vertically well-organized structure, the vertical thermal extend of the systems was studied with an algorithm developed as an extension module of the MS algorithm using ERA-Interim temperatures on several isobaric levels from 1000hPa to 100hPa on an 1.5°x1.5° resolution. The results verified that during both cold and warm period, cold-core anticyclones mainly affect the northern parts of the Mediterranean basin, with their behavior to be strongly regulated by cyclonic activity from the main storm track areas of the North Atlantic and Europe. On the other hand, warm-core anticyclones were found mainly in the southern Mediterranean and North African areas. Here, in order to get a perspective on the dynamic and thermodynamic processes in anticyclonic formation, a dynamical analysis at several vertical levels is performed. The study of mean fields of potential vorticity, temperature advection, vorticity advection at various levels can elucidate the role of upper and low levels during anticyclogenesis and system evolvement and help to further understand the dynamic mechanisms which are responsible for the anticyclogenesis over the Mediterranean region.

  18. Microtopography affecting critical transitions in drylands.

    Human and natural disturbances in drylands can suddenly induce a transition to a degraded ecosystem state that is difficult to reverse. Water availability for plants is essential for the resilience and stability of these water limited ecosystems. On hillslopes, the redistribution of surface water flow can be altered by microtopographic structures of mounds that develop under isolated plant patches, thereby affecting the vegetation. For low mounds, the flow velocity of surface water can reduce near the vegetation patches, thereby increasing run-on towards the vegetation. However, if mound height increases, it is expected that surface water circumvents the vegetation patch. Little is known yet about the influence of human pressures such as livestock grazing on these microtopographic structures. To investigate the effect of grazing on the microtopographic structures on hillslopes with patchy vegetation, a simple model has been developed and a field pilot study has been done. According to the model, grazing can alter the system in two ways. First, under low grazing pressure, trampling can increase the bare soil erodibility which amplifies the development of microtopographic structures. Second, under high grazing pressure, increased bare soil erodibility and reduced vegetation cover are operating simultaneously. Here, reduced protection of the soil by plants causes a relative decrease in the microtopographic structures compared to the low grazing pressure. Microtopographic field data were collected in SE Spain. The target species Stipa tennacissima is an unpalatable plant species, so only the effect of trampling was tested. These data suggest that mound development under the unpalatable plant only occurs at the highly grazed sites. This implies that the microtopography can significantly change due to trampling by grazers. Current research suggests that grazing changes the microtopography of hillslopes in drylands. However, further research is needed to understand how

  20. Affective psychotherapy in post-traumatic reactions guided by affective neuroscience: memory reconsolidation and play.

    2011-01-01

    This paper reviews the affective neuroscience dealing with the effects of traumatic events. We give an overview of the normal fear reactions, the pathological fear reaction, and the character of emotional episodic memories. We find that both emotions and emotional memories are a tripartite unit of sensory information, autonomic reaction, and motor impulse (the PRM complex). We propose that emotions and movements are part and parcel of the same complex. This is our main finding from the review of affective neuroscience, and from here we focus on psychotherapy with post-trauma reactions. The finding of the process of memory reconsolidation opens up a new treatment approach: affective psychotherapy focused on reconsolidation. The meaning of reconsolidation is that an emotional memory, when retrieved and being active, will rest in a labile form, amenable to change, for a brief period of time, until it reconsolidates in the memory. This leads us to the conclusion that emotions, affects, must be evoked during the treatment session and that positive emotion must come first, because safety must be part of the new memories. In the proposed protocol of affective psychotherapy based on reconsolidation the emotional episodic memory is relived in a safe and positive setting, focused in turn on the sensory experience, the autonomic reaction, and the motor impulse. Then it is followed by a fantasy of a different positive version of the same event. All in all treatment should provide a series of new memories without fear related to the original event. With the focus on the motor program, and the actions, there is a natural link to art therapy and to the mode of play, which can rehearse and fantasize new positive actions. PMID:22114539

    Full Text Available The aim of this study is to examine the mental processes that affect the piano performance. An efficient performance and education of the piano instrument depends on a complex systematic structure of a combination of some musical and technical challenges. To succeed in piano playing, one shall overcome the difficulties systematically over several years. Naturally, this process depends on many variables and the correct organization of the central nervous system plays a very important role on it. Having a complete understanding on the subject matter, it might guide the performance of piano playing and its educationBy the analysis of the historical processes, the activity of playing the piano was initially seen as a pure mechanical activity. However, at the beginning of the 20th Century, scholars had started to consider it not without its physiological and mental elements. This trend has reached today by gradually increasing its importance. Today in the contemporary piano performance and education, the mental processes are not being isolated from the whole matter of subject. In this study, the importance of the practicing methods that are based on correct organization of the central nervous system is set forth and to increase the efficiency of the piano performance, some practicing examples are given.

  2. How variation between individuals affects species coexistence.

    Although the effects of variation between individuals within species are traditionally ignored in studies of species coexistence, the magnitude of intraspecific variation in nature is forcing ecologists to reconsider. Compelling intuitive arguments suggest that individual variation may provide a previously unrecognised route to diversity maintenance by blurring species-level competitive differences or substituting for species-level niche differences. These arguments, which are motivating a large body of empirical work, have rarely been evaluated with quantitative theory. Here we incorporate intraspecific variation into a common model of competition and identify three pathways by which this variation affects coexistence: (1) changes in competitive dynamics because of nonlinear averaging, (2) changes in species' mean interaction strengths because of variation in underlying traits (also via nonlinear averaging) and (3) effects on stochastic demography. As a consequence of the first two mechanisms, we find that intraspecific variation in competitive ability increases the dominance of superior competitors, and intraspecific niche variation reduces species-level niche differentiation, both of which make coexistence more difficult. In addition, individual variation can exacerbate the effects of demographic stochasticity, and this further destabilises coexistence. Our work provides a theoretical foundation for emerging empirical interests in the effects of intraspecific variation on species diversity. PMID:27250037

    Steady state Iceland-spar calcite dissolution rates were measured at 25 °C in aqueous solutions containing 0.1 M NaCl and up to 0.05 M dissolved bicarbonate at pH from 7.9 to 9.1 in the presence of 13 distinct dissolved organic ligands in mixed-flow reactors. The organic ligands considered in this study include those most likely to be present in either (1) aquifers at the conditions pertinent to CO 2 sequestration or (2) soil/early diagenetic environments: acetate, phthalate, citrate, EDTA 4-, succinate, D-glucosaminate, L-glutamate, D-gluconate, 2,4-dihydroxybenzoate, 3,4-dihydroxybenzoate, fumarate, malonate, and gallate. Results show that the presence of extract, humic acid, pectin, and gum xanthan. In no case did the presence of <100 ppm of these organics change calcite dissolution rates by more than a factor of 2.5. Results obtained in this study suggest that the presence of aqueous organic anions negligibly affects calcite forward dissolution rates in most natural environments. Some effect on calcite reactivity may be observed, however, by the presence of organic anions if they change substantially the chemical affinity of the fluid with respect to calcite.

    Submergence, whether partial or complete, imparts some serious consequences on plants grown in flood prone ecosystems. Some plants can endure these conditions by embracing various survival strategies, including morphological adaptations and physiological adjustments. This review summarizes recent progress made in understanding of the stress and the acclimation responses of plants under waterlogged or submerged conditions. Waterlogging and submergence are often associated with hypoxia development, which may trigger various morphological traits and cellular acclimation responses. Ethylene, abscisic acid, gibberellic acid and other hormones play a crucial role in the survival process which is controlled genetically. Effects at the cellular level, including ATP management, starch metabolism, elemental toxicity, role of transporters and redox status have been explained. Transcriptional and hormonal interplay during this stress may provide some key aspects in understanding waterlogging and submergence tolerance. The level and degree of tolerance may vary depending on species or climatic variations which need to be studied for a proper understanding of waterlogging stress at the global level. The exploration of regulatory pathways and interplay in model organisms such as Arabidopsis and rice would provide valuable resources for improvement of economically and agriculturally important plants in waterlogging affected areas.

    Full Text Available Outdoor leisure activities are important for public health as well as family cohesiveness, yet environmental factors may easily affect someone’s ability to participate in such activities. We explored this with a focus on the social web-based treasure hunt game called Geocaching. We collected data on all US and Canadian geocaches from OpenCaching.com and conducted an online survey with twenty geocachers as a follow-up to our data analysis. Data analysis showed that geocaches were more often found in areas that were wealthier, better educated, younger, and more urban, and had higher population density and better weather. Survey results showed similar trends: Most people actively thought about where they would cache and tried to minimize risks, despite cache hiders thinking less about these concerns. These results further emphasize the importance of environmental factors when it comes to participation in outdoor activities and leads to Human–Computer Interaction design implications for location-based online social activities.

    Full Text Available Introduction. Emotionally dependent subjects may engage in controlling, restrictive, and aggressive behaviours, which limit their partner’s autonomy. The underlying causes of such behaviours are not solely based on levels of aggression, but act as a mean of maintaining the subject’s own sense of self-worth, identity, and general functioning. Objective. The aim of the paper is to explore the correlation between affective dependency and reactive/proactive aggression and to evaluate individual differences as predisposing factors for aggressive behaviour and emotional dependency. Methods. The Spouse-Specific Dependency Scale (SSDS and the Reactive Proactive Questionnaire (RPQ were administered to a sample of 3375 subjects. Results. In the whole sample, a positive correlation between emotional dependency and proactive aggression was identified. Differences with regard to sex, age group, and geographical distribution were evidenced for the scores of the different scales. Conclusion. A fundamental distinction between reactive and proactive aggression was observed, anchoring proactive aggression more strictly to emotional dependency. Sociocultural and demographical variables, together with the previous structuring of attachment styles, help to determine the scope, frequency, and intensity of the demands made to the partner, as well as to feed the fears of loss, abandonment, or betrayal.

  7. Could Atomic clocks be affected by neutrinos?

    An atomic clock is a clock device that uses an electronic transition frequency of the electromagnetic spectrum of atoms as a frequency standard in order to derive a time standard since time is the reciprocal of frequency. If the electronic transition frequencies are in an "optical region", we are talking in this case about optical atomic clocks. If they are in an "microwave region" these atomic clocks are made of the metallic element cesium so they are called Cesium atomic clocks. Atomic clocks are the most accurate time and frequency standards known despite the different perturbations that can affect them, a lot of researches were made in this domain to show how the transitions can be different for different type of perturbations..Since atomic clocks are very sensitive devices, based on coherent states (A coherent state tends to loose coherence after interacting). One question can arise (from a lot of questions) which is why cosmic neutrinos are not affecting these clocks? The answer to this question requir...

    Full Text Available People in conversation tend to accommodate the way they speak. It has been assumed that this tendency to imitate each other’s speech patterns serves to increase liking between partners in a conversation. Previous experiments examined the effect of perceived social attractiveness on the tendency to imitate someone else’s speech and found that vocal imitation increased when perceived attractiveness was higher. The present experiment extends this research by examining the inverse relationship and examines how overt vocal imitation affects attitudes. Participants listened to sentences spoken by two speakers of a regional accent (Glaswegian of English. They vocally repeated (speaking in their own accent without imitating the sentences spoken by a Glaswegian speaker, and subsequently imitated sentences spoken by a second Glaswegian speaker (order counterbalanced across participants. After each repeating or imitation session, participants completed a questionnaire probing the speakers’ perceived power, competence, and social attractiveness. Imitating had a positive effect on the perceived social attractiveness of the speaker compared to repeating. These results are interpreted in light of Communication Accommodation Theory.

    In a three-week study, the metabolism of the bronchodilator theophylline and its major metabolites formed by C-8 oxidation (1,3-dimethyluric acid) and N-demethylation (3-methylxanthine and 1-methyluric acid) was investigated in two healthy volunteers. Metabolic studies were performed following intravenous infusion of a single 6 mg/kg dose of aminophylline. During Week 1, theophylline was given alone (blank period), and during Weeks 2 and 3 it was given during oral coadministration of ofloxacin and enoxacin, respectively. Dosage of each quinolone was 200 mg twice daily for four days, starting three days prior to the theophylline infusion. During enoxacin coadministration, elimination half-lives of theophylline increased from 8.7 to 17.4 hours and from 6.1 to 12.3 hours, respectively. Total body clearance of theophylline decreased in both volunteers, whereas renal clearance did not alter. From this it was concluded that the decreased elimination results from a reduced metabolic clearance. During enoxacin coadministration, the formation of the metabolites 1-methyluric acid and 3-methylxanthine clearly was decreased, whereas the formation of 1,3-dimethyluric acid was less affected compared with the blank period. Interference with theophylline disposition by enoxacin is based predominantly on inhibition of microsomal N-demethylation. Ofloxacin comedication did not cause a change in the plasma parameters or renal excretion of theophylline and its metabolites compared with the blank period. PMID:2603893

    Toxoneuron nigriceps (Viereck) (Hymenoptera, Braconidae) and Campoletis sonorensis (Cameron) (Hymenoptera, Ichneumonidae) are solitary endoparasitoids of the tobacco budworm, Heliothis virescens (Fabricius) (Lepidoptera, Noctuidae). They provide biological control of H. virescens populations in Southeastern US agricultural production systems. Field and greenhouse experiments conducted from 2011-2014 compared parasitism rates of parasitoids that developed inside H. virescens larvae fed on tobacco plants treated with and without imidacloprid. The parasitoids in our study did not have a similar response. Toxoneuron nigriceps had reduced parasitism rates, but parasitism rates of C. sonorensis were unaffected. Preliminary data indicate that adult female lifespans of T. nigriceps are also reduced. ELISA was used to measure concentrations of neonicotinoids, imidacloprid and imidacloprid metabolites in H. virescens larvae that fed on imidacloprid-treated plants and in the parasitoids that fed on these larvae. Concentrations were detectable in the whole bodies of parasitized H. virescens larvae, T. nigriceps larvae and T. nigriceps adults, but not in C. sonorensis larvae and adults. These findings suggest that there are effects of imidacloprid on multiple trophic levels, and that insecticide use may differentially affect natural enemies with similar feeding niches.

  11. Can Solution Supersaturation Affect Protein Crystal Quality?

    Science.gov (United States)

    Gorti, Sridhar

    2013-01-01

    The formation of large protein crystals of "high quality" is considered a characteristic manifestation of microgravity. The physical processes that predict the formation of large, high quality protein crystals in the microgravity environment of space are considered rooted in the existence of a "depletion zone" in the vicinity of crystal. Namely, it is considered reasonable that crystal quality suffers in earth-grown crystals as a result of the incorporation of large aggregates, micro-crystals and/or large molecular weight "impurities", processes which are aided by density driven convective flow or mixing at the crystal-liquid interface. Sedimentation and density driven convection produce unfavorable solution conditions in the vicinity of the crystal surface, which promotes rapid crystal growth to the detriment of crystal size and quality. In this effort, we shall further present the hypothesis that the solution supersaturatoin at the crystal surface determines the growth mechanism, or mode, by which protein crystals grow. It is further hypothesized that protein crystal quality is affected by the mechanism or mode of crystal growth. Hence the formation of a depletion zone in microgravity environment is beneficial due to inhibition of impurity incorporatoin as well as preventing a kinetic roughening transition. It should be noted that for many proteins the magnitude of neither protein crystal growth rates nor solution supersaturation are predictors of a kinetic roughening transition. That is, the kinetic roughening transition supersaturation must be dtermined for each individual protein.

  12. Drosophila Porin/VDAC affects mitochondrial morphology.

    Directory of Open Access Journals (Sweden)

    Jeehye Park

    Full Text Available Voltage-dependent anion channel (VDAC has been suggested to be a mediator of mitochondrial-dependent cell death induced by Ca(2+ overload, oxidative stress and Bax-Bid activation. To confirm this hypothesis in vivo, we generated and characterized Drosophila VDAC (porin mutants and found that Porin is not required for mitochondrial apoptosis, which is consistent with the previous mouse studies. We also reported a novel physiological role of Porin. Loss of porin resulted in locomotive defects and male sterility. Intriguingly, porin mutants exhibited elongated mitochondria in indirect flight muscle, whereas Porin overexpression produced fragmented mitochondria. Through genetic analysis with the components of mitochondrial fission and fusion, we found that the elongated mitochondria phenotype in porin mutants were suppressed by increased mitochondrial fission, but enhanced by increased mitochondrial fusion. Furthermore, increased mitochondrial fission by Drp1 expression suppressed the flight defects in the porin mutants. Collectively, our study showed that loss of Drosophila Porin results in mitochondrial morphological defects and suggested that the defective mitochondrial function by Porin deficiency affects the mitochondrial remodeling process.

  13. Factors affecting seismic response of submarine slopes

    2006-01-01

    Full Text Available The response of submerged slopes on the continental shelf to seismic or storm loading has become an important element in the risk assessment for offshore structures and 'local' tsunami hazards worldwide. The geological profile of these slopes typically includes normally consolidated to lightly overconsolidated soft cohesive soils with layer thickness ranging from a few meters to hundreds of meters. The factor of safety obtained from pseudo-static analyses is not always a useful measure for evaluating the slope response, since values less than one do not necessarily imply slope failure with large movements of the soil mass. This paper addresses the relative importance of different factors affecting the response of submerged slopes during seismic loading. The analyses use a dynamic finite element code which includes a constitutive law describing the anisotropic stress-strain-strength behavior of normally consolidated to lightly overconsolidated clays. The model also incorporates anisotropic hardening to describe the effect of different shear strain and stress histories as well as bounding surface principles to provide realistic descriptions of the accumulation of the plastic strains and excess pore pressure during successive loading cycles. The paper presents results from parametric site response analyses on slope geometry and layering, soil material parameters, and input ground motion characteristics. The predicted maximum shear strains, permanent deformations, displacement time histories and maximum excess pore pressure development provide insight of slope performance during a seismic event.

    1986-01-01

    In order to provide information about the hypothesis that endogenous opioids mediate the reinforcing properties of cigarette smoking, the present study examined the effects of naloxone, an opioid antagonist, on cigarette smoking in seven normal volunteers. The study used experimental procedures that had previously been shown sensitive for detecting the effects of other drugs, (including a nicotine antagonist) on smoking. Isolated subjects smoked their regular brand of cigarettes freely in a naturalistic laboratory environment while watching television or reading. Sixty minutes before each 2 h smoking session subjects received an IM injection of naloxone HCl (0.0625, 0.25, 1.0, or 4.0 mg/kg) or placebo. Each subject received each treatment three times in a mixed order across days. Naloxone did not significantly affect any measure of cigarette smoking including number of cigarettes, number of puffs, or expired air carbon monoxide level. Naloxone did, however, produce significant dose-related increases in subject ratings of yawning, stretching, and relaxation. The results of the present study provide no support for the endogenous opioid theory of smoking reinforcement. PMID:3088648

    The rate of ATP synthesis by creatine kinase extracted from V. xanthia venom was shown to depend on the magnetic field. The yield of ATP produced by enzymes with 24Mg2+ and 26Mg2+ ions in catalytic sites increases by 7-8% at 55 mT and then decreases at 80 mT. For enzyme with 25Mg2+ ion in a catalytic site, the ATP yield increases by 50% and 70% in the fields 55 and 80 mT, respectively. In the Earth field the rate of ATP synthesis by enzyme, in which Mg2+ ion has magnetic nucleus 25Mg, is 2.5 times higher than that by enzymes, in which Mg2+ ion has nonmagnetic, spinless nuclei 24Mg or 26Mg. Both magnetic field effect and magnetic isotope effect demonstrate that the ATP synthesis is an ion-radical process, affected by Zeeman interaction and hyperfine coupling in the intermediate ion-radical pair.

  16. Atmospheric stability affects wind turbine power collection

    International Nuclear Information System (INIS)

    The power generated by a wind turbine largely depends on the wind speed. During time periods with identical hub-height wind speeds but different shapes to the wind profile, a turbine will produce different amounts of power. This variability may be induced by atmospheric stability, which affects profiles of mean wind speed, direction and turbulence across the rotor disk. Our letter examines turbine power generation data, segregated by atmospheric stability, in order to investigate power performance dependences at a West Coast North American wind farm. The dependence of power on stability is clear, regardless of whether time periods are segregated by three-dimensional turbulence, turbulence intensity or wind shear. The power generated at a given wind speed is higher under stable conditions and lower under strongly convective conditions: average power output differences approach 15%. Wind energy resource assessment and day ahead power forecasting could benefit from increased accuracy if atmospheric stability impacts were measured and appropriately incorporated in power forecasts, e.g., through the generation of power curves based on a range of turbulence regimes.

    Purpose: To investigate the correlation of various corneal hysteresis (CH) factors in Chinese adults. Methods: From January 2009 to November 2011, the healthy right eyes of a total of 292 adults were recruited into the study. Goldmann-correlated intraocular pressure (IOPG) and CH were measured using an ocular response analyzer (ORA). Central corneal thickness was measured using the ORA’s in-tegrated handheld ultrasonic pachymeter. The IOLMaster was used to obtain the ocular biometric measurements including axial length, anterior chamber depth, and keratometric values. The Pearson correlation coefficient was used to test correla-tions between CH and quantitative factors. The chi-square test was used to detect differences in categorical values. Results: Longer axial length (P=0.0001), lower IOPG (P=0.03), older age(P=0.003),and thinner central corneal thick-ness (P=0.0001) were significantly associated with lower CH. The anterior chamber depth (P=0.34), gender (P=0.23), and corneal curvature (P=0.18) had no relationship to CH. Conclusion:Various factors including axial length, intraocular pressure, age, and central corneal thickness can affect measure-ment of corneal biomechanical properties in Chinese adults. But the anterior chamber depth, gender, and corneal curvature were irrelevant to CH.

    To understand how fisheries affect parasites, we conducted a meta-analysis of studies that contrasted parasite assemblages in fished and unfished areas. Parasite diversity was lower in hosts from fished areas. Larger hosts had a greater abundance of parasites, suggesting that fishing might reduce the abundance of parasites by selectively removing the largest, most heavily parasitized individuals. After controlling for size, the effect of fishing on parasite abundance varied according to whether the host was fished and the parasite's life cycle. Parasites of unfished hosts were more likely to increase in abundance in response to fishing than were parasites of fished hosts, possibly due to compensatory increases in the abundance of unfished hosts. While complex life cycle parasites tended to decline in abundance in response to fishing, directly transmitted parasites tended to increase. Among complex life cycle parasites, those with fished hosts tended to decline in abundance in response to fishing, while those with unfished hosts tended to increase. However, among directly transmitted parasites, responses did not differ between parasites with and without fished hosts. This work suggests that parasite assemblages are likely to change substantially in composition in increasingly fished ecosystems, and that parasite life history and fishing status of the host are important in predicting the response of individual parasite species or groups to fishing.

    The objective of this research is the exploration of seat belt use in Greece and particularly the identification of the parameters affecting seat belt use in Greece. A national field survey was conducted for the analytical recording of seat belt use. A binary logistic regression model was developed, and the impact of each parameter on seat belt use in Greece was quantified. Parameters included in the model concern characteristics of car occupants (gender, age and position in the car), the type of the car and the type of the road network. The data collection revealed that in Greece, the non-use of seat belt on the urban road network was higher than on the national and rural road network and young and older men use seat belts the least. The developed model showed that travelling on a national road is negative for not wearing the seat belt. Finally, the variable with the highest impact on not wearing a seat belt is being a passenger on the back seats. PMID:21452095

    Nucleolin is present in diverse cellular compartments and is involved in a variety of cellular processes from nucleolar structure and function to intracellular trafficking, cell adhesion and migration. Recently, nucleolin has been localized at the mature centriole where it is involved in microtubule nucleation and anchoring. Although this new function of nucleolin linked to microtubule regulation has been identified, the global effects of nucleolin on microtubule dynamics have not been addressed yet. In the present study, we analyzed the roles of nucleolin protein levels on global microtubule dynamics by tracking the EB3 microtubule plus end binding protein in live cells. We have found that during microtubule growth phases, nucleolin affects both the speed and life time of polymerization and by analyzing catastrophe events, we showed that nucleolin reduces catastrophe frequency. This new property of nucleolin was then confirmed in a cold induced microtubule depolymerization experiment in which we have found that cold resistant microtubules were totally destabilized in nucleolin depleted cells. Altogether, our data demonstrate a new function of nucleolin on microtubule stabilization, thus bringing novel insights into understanding the multifunctional properties of nucleolin in healthy and cancer cells.

    Full Text Available Live weights, weight gains and some body measurements at different ages of Eastern Anatolian Red Cattle (EAR were determined and some environmental factors affecting on these traits were investigated. The effect of dam’s age on the birth weight was highly significant (P<0.01. Although the lowest birth weight was obtained from calves of dams at the 3 years of age, the highest birth weight was obtained from calves given birth by cows at the 5 years of age. The males had heavier live weights and weight gains at different ages than the females. The effect of the sex on the live weights except for 9 and 12 months weights was found as highly significant (P<0.01. Feeding of the calves with different amount of milk had significant (P<0.01 influence on the 3, 6 and 9 months weights as well as weight gains. The effect of the years on the daily weight gains in EAR was also highly significant (P<0.01. The results shows the importance of the environmental effects on the traits studied and revealed that there is need for them to be corrected prior to the improvement studies.

    Full Text Available Abstract Nowaday, zoonoses are an important cause of human parasitic diseases worldwide and a major threat to the socio-economic development, mainly in developing countries. Importantly, zoonotic helminths that affect human eyes (HIE may cause blindness with severe socio-economic consequences to human communities. These infections include nematodes, cestodes and trematodes, which may be transmitted by vectors (dirofilariasis, onchocerciasis, thelaziasis, food consumption (sparganosis, trichinellosis and those acquired indirectly from the environment (ascariasis, echinococcosis, fascioliasis. Adult and/or larval stages of HIE may localize into human ocular tissues externally (i.e., lachrymal glands, eyelids, conjunctival sacs or into the ocular globe (i.e., intravitreous retina, anterior and or posterior chamber causing symptoms due to the parasitic localization in the eyes or to the immune reaction they elicit in the host. Unfortunately, data on HIE are scant and mostly limited to case reports from different countries. The biology and epidemiology of the most frequently reported HIE are discussed as well as clinical description of the diseases, diagnostic considerations and video clips on their presentation and surgical treatment.

    Full Text Available Automatic defense responses promote survival and appropriate action under threat. They have also been associated with the development of threat-related psychiatric syndromes. Targeting such automatic responses during threat may be useful in populations with frequent threat exposure. Here, two experiments explored whether mental imagery as a pre-trauma manipulation could influence fear bradycardia (a core characteristic of freezing during subsequent analogue trauma (affective picture viewing. Image-based interventions have proven successful in the treatment of threat-related disorders, and are easily applicable. In Experiment 1 43 healthy participants were randomly assigned to an imagery script condition. Participants executed a passive viewing task with blocks of neutral, pleasant and unpleasant pictures after listening to an auditory script that was either related (with a positive or a negative outcome or unrelated to the unpleasant pictures from the passive viewing task. Heart rate was assessed during script listening and during passive viewing. Imagining negative related scripts resulted in greater bradycardia (neutral-unpleasant contrast than imagining positive scripts, especially unrelated. This effect was replicated in Experiment 2 (N = 51, again in the neutral-unpleasant contrast. An extra no-script condition showed that bradycardia was not induced by the negative related script, but rather that a positive script attenuated bradycardia. These preliminary results might indicate reduced vigilance after unrelated positive events. Future research should replicate these findings using a larger sample. Either way, the findings show that highly automatic defense behavior can be influenced by relatively simple mental imagery manipulations.

  5. Contrast affects flicker and speed perception differently

    1997-01-01

    We have previously shown that contrast affects speed perception, with lower-contrast, drifting gratings perceived as moving slower. In a recent study, we examined the implications of this result on models of speed perception that use the amplitude of the response of linear spatio-temporal filters to determine speed. In this study, we investigate whether the contrast dependence of speed can be understood within the context of models in which speed estimation is made using the temporal frequency of the response of linear spatio-temporal filters. We measured the effect of contrast on flicker perception and found that contrast manipulations produce opposite effects on perceived drift rate and perceived flicker rate, i.e., reducing contrast increases the apparent temporal frequency of counterphase modulated gratings. This finding argues that, if a temporal frequency-based algorithm underlies speed perception, either flicker and speed perception must not be based on the output of the same mechanism or contrast effects on perceived spatial frequency reconcile the disparate effects observed for perceived temporal frequency and speed.

    The provision of anaesthesia requires a high level of knowledge, sound judgement, fast and accurate responses to clinical situations, and the capacity for extended periods of vigilance. With changing expectations and arising medico-legal issues, anaesthesiologists are working round the clock to provide efficient and timely health care services, but little is thought whether the “sleep provider” is having adequate sleep. Decreased performance of motor and cognitive functions in a fatigued anaesthesiologist may result in impaired judgement, late and inadequate responses to clinical changes, poor communication and inadequate record keeping, all of which affect the patient safety, showing without doubt the association of sleep debt to the adverse events and critical incidents. Perhaps it is time that these issues be promptly addressed to prevent the silent perpetuation of a problem that is pertinent to our health and our profession. We endeavour to focus on the evidence that links patient safety to fatigue and sleepiness of health care workers and specifically on anaesthesiologists. The implications of sleep debt are deep on patient safety and strategies to prevent this are the need of the hour. PMID:21431047

    Magnetite nanoparticles --MNPs-- are innovative materials used in biological and medical applications. They respond to magnetic field through the superparamagnetic behavior at room temperature. In this study, the MNPs were synthesized via the chemical co-precipitation method using various coating agents. Fatty acids, found naturally in the animal fats, can be used as a coating agent. Oleic acid and hexanoic acid were chosen as the surface modification agents to study the improvement in the suspension of MNPs in water and the magnetite properties. Suspension stability, particle size, and electrical conductivity of MNPs are critically affected by the modification process. The well-dispersed MNPs in water can be improved by the surface modification and the oleic acid coated MNPs possess excellent suspension stability over 1 week. The particle size of MNPs increases up to 40 nm using oleic acid coated MNPs. The electrical conductivity of the smallest particle size is 1.3x10-3 S/cm, which is 5 times higher than that of the largest particle, suggesting potential applications as a biomedical material under both of the electrical and magnetic fields.

    Traditional conceptions of spoken language assume that speech recognition and talker identification are computed separately. Neuropsychological and neuroimaging studies imply some separation between the two faculties, but recent perceptual studies suggest better talker recognition in familiar languages than unfamiliar languages. A familiar-language benefit in talker recognition potentially implies strong ties between the two domains. However, little is known about the nature of this language familiarity effect. The current study investigated the relationship between speech and talker processing by assessing bilingual and monolingual listeners' ability to learn voices as a function of language familiarity and age of acquisition. Two effects emerged. First, bilinguals learned to recognize talkers in their first language (Korean) more rapidly than they learned to recognize talkers in their second language (English), while English-speaking participants showed the opposite pattern (learning English talkers faster than Korean talkers). Second, bilinguals' learning rate for talkers in their second language (English) correlated with age of English acquisition. Taken together, these results suggest that language background materially affects talker encoding, implying a tight relationship between speech and talker representations. PMID:24211437

    Opening paragraph: Tidal and nontidal wetlands in the Chesapeake Bay watershed provide vital hydrologic, water-quality, and ecological functions. Situated at the interface of land and water, these valuable habitats are vulnerable to alteration and loss by human activities including direct conversion to non-wetland habitat by dredge-and-fill activities from land development, and to the effects of excessive nutrients, altered hydrology and runoff, contaminants, prescribed fire management, and invasive species. Processes such as sea-level rise and climate change also impact wetlands. Although local, State, and Federal regulations provide for protection of wetland resources, the conversion and loss of wetland habitats continue in the Bay watershed. Given the critical values of wetlands, the Chesapeake 2000 Agreement has a goal to achieve a net gain in wetlands by restoring 25,000 acres of tidal and nontidal wetlands by 2010. The USGS has synthesized findings on three topics: (1) sea-level rise and wetland loss, (2) wetland restoration, and (3) factors affecting wetland diversity.

    Full Text Available Absorption of drugs from the gastrointestinal tract is a complex process the variability of which is influenced by many physicochemical and physiologic factors. The two most important physicochemical factors that affect both the extent and the rate of absorption are lipophilicity and solubility. The rate and extent of absorption are governed by the solubility, permeability and stability of the drug, with solubility being a pH-dependent parameter for weak acids and bases. The gastrointestinal tract can be viewed as discrete sections with a variety of differential local pH environments ranging from the acidic stomach to the more basic small intestine. The multiple peaking, double peaking or secondary peaking phenomena can occur in the disposition of a variety of xenobiotics during drug development (the pre-clinical phase and in subsequent clinical studies and use. The physicochemical and physiological mechanisms underlying the occurrence of this phenomenon are often multi factorial and include but are not limited to solubility-limited absorption, modified-release formulations, complexation, enterohepatic recirculation, gastric emptying and the intestinal transit time, site-specific absorption, gastric secretion-enteral reabsorption. Double peak absorption has been described with several orally administered drugs such as cimetidine furosemide, piroxicam, ranitidine, talinolol, alprazolam and phenazopyridine.

    Full Text Available This study was undertaken to identify the factors affecting sugarcane production in Pakistan. Data were collected from 387 sugarcane growers from Sindh, Punjab and NWFP province. Data were collected during the period 2007-08. The study reveals that the costs of inputs of sugarcane i.e. urea, DAP, FYM, land preparation, seed and its application, weeding and cost of irrigation were the important factors which influenced on the returns of sugarcane growers. The effectiveness was examined by using the Cobb-Douglas production function; MVP and allocative efficiency were calculated. The coefficient of multiple determinations R2 was 0.9249, which indicated that 92% variation in the cost of inputs was explained by all explanatory variables and the adjusted R2 was 92%. The F-value was 666.94 and was highly significant at 5% level of significance, indicating that the regression model was well fitted. The high prices of inputs, low price of output, delay in payments and lack of scientific knowledge were the major problems in sugarcane production. In order to enhance the productivity of sugarcane in the country, government should solve the identified problems to increase the income of sugarcane growers.

  14. Cadmium affects retinogenesis during zebrafish embryonic development

    International Nuclear Information System (INIS)

    Ocular malformations are commonly observed in embryos of aquatic species after exposure to toxicants. Using zebrafish embryos as the model organism, we showed that cadmium exposure from sphere stage (4 hpf) to end of segmentation stage (24 hpf) induced microphthalmia in cadmium-treated embryos. Embryos with eye defects were then assessed for visual abilities. Cadmium-exposed embryos were behaviorally blind, showing hyperpigmentation and loss of camouflage response to light. We investigated the cellular basis of the formation of the small eyes phenotype and the induction of blindness by studying retina development and retinotectal projections. Retinal progenitors were found in cadmium-treated embryos albeit in smaller numbers. The number of retinal ganglion cells (RGC), the first class of retinal cells to differentiate during retinogenesis, was reduced, while photoreceptor cells, the last batch of retinal neurons to differentiate, were absent. Cadmium also affected the propagation of neurons in neurogenic waves. The neurons remained in the ventronasal area and failed to spread across the retina. Drastically reduced RGC axons and disrupted optic stalk showed that the optic nerves did not extend from the retina beyond the chiasm into the tectum. Our data suggested that impairment in neuronal differentiation of the retina, disruption in RGC axon formation and absence of cone photoreceptors were the causes of microphthalmia and visual impairment in cadmium-treated embryos

  15. Factors affecting radiolytic effects in food

    International Nuclear Information System (INIS)

    On basis of radiation chemical considerations supported by model system studies, several general predictions can be made regarding the influence of specific parameters on the chemical effects in irradiated foods. Among the parameters considered are: food composition, physical state of components, irradiation temperature, dose-rate, and total dose. Composition determines the type and extent of reactions initiated by both direct and indirect radiolytic interaction. The multiphasic character of foods influences cross reactions between components. State of hydration introduces both physical and chemical aspects into these considerations. Irradiating systems in which the water is frozen changes substantially the chemical effects because the diffusion of reactive entities is impeded. Temperature, especially in frozen systems, has a specific effect on the type and extent of reactions that could occur. Dose and dose-rate, insofar as they affect the pathways for reaction of intermediate species with the original or new components, also determine the type and amount of final radiolysis products. Illustrations of many of these features of the chemistry have been drawn from experiments on model systems of proteins, frozen aqueous solutions, and compounds derived from lipids, as well as from irradiated meats and poultry. These considerations and related experimental results explain the validity of using chemical data to obtain clearances and to extend clearances from approved food to other foods or to other irradiation conditions.

    Research on the structure of children's affect is limited. It is possible that children's perception of their own affect might be less differentiated than that of adults. Support for the 2-factor model of positive and negative affect and the pleasure-arousal model suggests that children in middle childhood can distinguish positive and negative affect as well as valence and arousal. Whether children are able to differentiate further aspects of affect, as proposed by the 3-dimensional model of affect (good-bad mood, alertness-tiredness, calmness-tension), is an unresolved issue. The aim of our study was the comparison of these 3 affect models to establish how differentiated children experience their affect and which model best describes affect in children. We examined affect structures on the between- and within-person level, acknowledging that affect varies across time and that no valid interpretation of either level is feasible if both are confounded. For this purpose, 214 children (age 8-11 years) answered affect items once a day for 5 consecutive days on smartphones. We tested all affect models by means of 2-level confirmatory factor analysis. Although all affect models had an acceptable fit, the 3-dimensional model best described affect in children on both the within- and between-person level. Thus, children in middle childhood can already describe affect in a differentiated way. Also, affect structures were similar on the within- and between-person level. We conclude that in order to acquire a thorough picture of children's affect, measures for children should include items of all 3 affect dimensions. (PsycINFO Database Record PMID:26280488

We give an overview of the normal fear reactions, the pathological fear reaction, and the character of emotional episodic memories. We find that both emotions and emotional memories are a tripartite unit of sensory information, autonomic reaction, and motor impulse (the PRM complex. We propose that emotions and movements are part and parcel of the same complex. This is our main finding from the review of affective neuroscience, and from here we focus on psychotherapy with post-trauma reactions. The finding of the process of memory reconsolidation opens up a new treatment approach: affective psychotherapy focused on reconsolidation. The meaning of reconsolidation is that an emotional memory, when retrieved and being active, will rest in a labile form, amenable to change, for a brief period of time, until it reconsolidates in the memory. This leads us to the conclusion that emotions, affects, must be evoked during the treatment session and that positive emotion must come first, because safety must be part of the new memories.

    Jones, J. B. L.; Bentley, R. D.; Dyer, C.; Shaw, A.

    In Europe, legislation requires the airline industry to monitor the occupational exposure of aircrew to cosmic radiation. However, there are other significant impacts of space weather phenomena on the technological systems used for day-to-day operations which need to be considered by the airlines. These were highlighted by the disruption caused to the industry by the period of significant solar activity in late October and early November 2003. Next generation aircraft will utilize increasingly complex avionics as well as expanding the performance envelopes. These and future generation platforms will require the development of a new air-space management infrastructure with improved position accuracy (for route navigation and landing in bad weather) and reduced separation minima in order to cope with the expected growth in air travel. Similarly, greater reliance will be placed upon satellites for command, control, communication and information (C3I) of the operation. However, to maximize effectiveness of this globally interoperable C3I and ensure seamless fusion of all components for a safe operation will require a greater understanding of the space weather affects, their risks with increasing technology, and the inclusion of space weather information into the operation. This paper will review space weather effects on air transport and the increasing risks for future operations cause by them. We will examine how well the effects can be predicted, some of the tools that can be used and the practicalities of using such predictions in an operational scenario. Initial results from the SOARS ESA Space Weather Pilot Project will also be discussed,

    The occurrence of emerging infectious diseases in wildlife populations is increasing, and changes in environmental conditions have been hypothesized as a potential driver. For example, warmer ambient temperatures might favor pathogens by providing more ideal conditions for propagation or by stressing hosts. Our objective was to determine if water temperature played a role in the pathogenicity of an emerging pathogen (ranavirus) that infects ectothermic vertebrate species. We exposed larvae of four amphibian species to a Frog Virus 3 (FV3)-like ranavirus at two temperatures (10 and 25°C). We found that FV3 copies in tissues and mortality due to ranaviral disease were greater at 25°C than at 10°C for all species. In a second experiment with wood frogs (Lithobates sylvaticus), we found that a 2°C change (10 vs. 12°C) affected ranaviral disease outcomes, with greater infection and mortality at 12°C. There was evidence that 10°C stressed Cope's gray tree frog (Hyla chrysoscelis) larvae, which is a species that breeds during summer-all individuals died at this temperature, but only 10% tested positive for FV3 infection. The greater pathogenicity of FV3 at 25°C might be related to faster viral replication, which in vitro studies have reported previously. Colder temperatures also may decrease systemic infection by reducing blood circulation and the proportion of phagocytes, which are known to disseminate FV3 through the body. Collectively, our results indicate that water temperature during larval development may play a role in the emergence of ranaviruses. PMID:27283058

  20. Benign meningiomas: primary treatment selection affects survival

    International Nuclear Information System (INIS)

    Purpose: To examine the effect of primary treatment selection on outcomes for benign intracranial meningiomas at the University of Florida. Methods and Materials: For 262 patients, the impact of age, Karnofsky performance status, pathologic features, tumor size, tumor location, and treatment modality on local control and cause-specific survival was analyzed (minimum potential follow-up, 2 years; median follow-up, 8.2 years). Extent of surgery was classified by Simpson grade. Treatment groups: surgery alone (n = 229), surgery and postoperative radiotherapy (RT) (n = 21), RT alone (n = 7), radiosurgery alone (n = 5). Survival analysis: Kaplan-Meier method with univariate and multivariate analysis. Results: At 15 years, local control was 76% after total excision (TE) and 87% after subtotal excision plus RT (SE+RT), both significantly better (p = 0.0001) than after SE alone (30%). Cause-specific survival at 15 years was reduced after treatment with SE alone (51%), compared with TE (88%) or SE+RT (86%) (p = 0.0003). Recurrence after primary treatment portended decreased survival, independent of initial treatment group or salvage treatment selection (p = 0.001). Atypical pathologic features predicted reduced 15-year local control (54 vs. 71%) and cause-specific survival rates (57 vs. 86%). Multivariate analysis for cause-specific survival revealed treatment group (SE vs. others; p = 0.0001), pathologic features (atypical vs. typical; p = 0.0056), and Karnofsky performance status (≥80 vs. <80; p = 0.0153) as significant variables. Conclusion: Benign meningiomas are well managed by TE or SE+RT. SE alone is inadequate therapy and adversely affects cause-specific survival. Atypical pathologic features predict a poorer outcome, suggesting possible benefit from more aggressive treatment. Because local recurrence portends lower survival rates, primary treatment choice is important

  1. Heme oxygenase-1 deletion affects stress erythropoiesis.

    Directory of Open Access Journals (Sweden)

    Full Text Available BACKGROUND: Homeostatic erythropoiesis leads to the formation of mature red blood cells under non-stress conditions, and the production of new erythrocytes occurs as the need arises. In response to environmental stimuli, such as bone marrow transplantation, myelosuppression, or anemia, erythroid progenitors proliferate rapidly in a process referred to as stress erythropoiesis. We have previously demonstrated that heme oxygenase-1 (HO-1 deficiency leads to disrupted stress hematopoiesis. Here, we describe the specific effects of HO-1 deficiency on stress erythropoiesis. METHODOLOGY/PRINCIPAL FINDINGS: We used a transplant model to induce stress conditions. In irradiated recipients that received hmox(+/- or hmox(+/+ bone marrow cells, we evaluated (i the erythrocyte parameters in the peripheral blood; (ii the staining intensity of CD71-, Ter119-, and CD49d-specific surface markers during erythroblast differentiation; (iii the patterns of histological iron staining; and (iv the number of Mac-1(+-cells expressing TNF-α. In the spleens of mice that received hmox(+/- cells, we show (i decreases in the proerythroblast, basophilic, and polychromatophilic erythroblast populations; (ii increases in the insoluble iron levels and decreases in the soluble iron levels; (iii increased numbers of Mac-1(+-cells expressing TNF-α; and (iv decreased levels of CD49d expression in the basophilic and polychromatophilic erythroblast populations. CONCLUSIONS/SIGNIFICANCE: As reflected by effects on secreted and cell surface proteins, HO-1 deletion likely affects stress erythropoiesis through the retention of erythroblasts in the erythroblastic islands of the spleen. Thus, HO-1 may serve as a therapeutic target for controlling erythropoiesis, and the dysregulation of HO-1 may be a predisposing condition for hematologic diseases.

    Full Text Available Emotion is caused by many factors, some of which are evolutionary, neurological, chemical, environmental, societal, personal and religious. Mostly, however, we are oblivious of the causal factors, many of which may function on a biological level or subconsciously, although the emotional effect is experienced physically and consciously. Emotions change as the trigger mechanisms in the cultural context change. This usually happens unnoticed over long periods. Internet databases have now made it possible to study the use of emotive words; this point is discussed. Of particular interest is the interaction between emotion and reason. Models that reduce emotion to the physical level are scrutinised critically. Reason is not emotionless and emotion is not always irrational. The close interrelationship of emotion and reason often makes it difficult to distinguish accurately between the two. The so-called affective turn takes cognisance of cultural, social, religious and other environmental factors; this broader approach clarifies the importance of affect’s role in rationality. One way of viewing emotion and affect is to look at the accompanying language; here the role of metaphor and narrative is pertinent. The traditional elevation of reason above emotion is examined critically as part of the affective turn that broadens the meaning and scope of emotions. I focus on the role of emotion in religion and factors that influence it, and explore the accent of affect in new spiritualities.

    A history of childhood trauma is reportedly more prevalent in people suffering from psychosis than in the general population. Childhood trauma has also been linked to cognitive abnormalities in adulthood, and cognitive abnormalities, in turn, are one of the key clinical features of psychosis. Therefore, this study investigated whether there was a relationship between childhood trauma and cognitive function in patients with first-episode psychosis. The potential impact of diagnosis (schizophrenia or affective psychosis) and gender on this association was also examined.

  4. Relations between affective music and speech: Evidence from dynamics of affective piano performance and speech production

    2015-07-01

    Full Text Available This study compares affective piano performance with speech production from the perspective of dynamics: unlike previous research, this study uses finger force and articulatory effort as indexes reflecting the dynamics of affective piano performance and speech production respectively. Moreover, for the first time physical constraints such as piano fingerings and speech articulatory distance are included due to their potential contribution to different patterns of dynamics. A piano performance experiment and speech production experiment were conducted in four emotions: anger, fear, happiness and sadness. The results show that in both piano performance and speech production, anger and happiness generally have high dynamics while sadness has the lowest dynamics, with fear in the middle. Fingerings interact with fear in the piano experiment and articulatory distance interacts with anger in the speech experiment, i.e., large physical constraints produce significantly higher dynamics than small physical constraints in piano performance under the condition of fear and in speech production under the condition of anger. Using production experiments, this study firstly supports previous perception studies on relations between affective music and speech. Moreover, this is the first study to show quantitative evidence for the importance of considering motor aspects such as dynamics in comparing music performance and speech production in which motor mechanisms play a crucial role.

  10. Factors Affecting Career Progress of MBA Students

    Vivien T. Supangco

    2001-06-01

    Full Text Available This paper explored the factors that affect career progress of students in the MBA program of the University of the Philippines.To understand career progression, four measures of career progress were used in this study, namely: number of promotions, number of years in between promotions, total cash compensation, and number of administrative levels from the company president. On the other hand, the factors used to explain career progess included human capital, organizational, interpersonal and demographic variables.The results showed that the different measures of career progress had distinct determinants implying different dynamics. It appeared that measures of career progress that are sensitive to the value employers attach to the individual (Whitely, Dougherty, & Dreher, 1991 such as total compensation, total number of promotion and years per promotion were related with human capital factors such as work experience and number of companies worked for. On the other hand, measures that relate to centrality if the position, in which market forces have less impact, were associated with organizational variables such as organization size and the demographic variable gender.While gender did not explain variation in total compensation, number of promotions and number of uears between promotions, these null results are important for two reasons. First, it implies that the female MBA students were at par with their male counterparts as fas as these measures of career progress are concerned. Second, it challenges the generalizability of the finding of gender segregation at the organizational level-where men receive significantly higher wages that women-which is a common finding among studies done in the United States. The results using the MBA students as sample show that income and promotion parity may indeed be achievable and this brings hope to women in general.However, the statistical significance of gender in explaining career progress as centrality

    Full Text Available Objective: to evaluate the efficiency and safety of different therapy regimens for depression in relation to the clinical type of bipolar affective disorders (BAD and to choose optimal treatment regimens for depression in BAD type I (BADI and BAD type II (BADII.Patients and methods. A total of 65 depressive patients, including 25 with BADI and 37 with BADII, were examined. 212 depressive episodes were analyzed in BAD patients, of them there were 74 with BADI and 138 with BADII. The patients with BADI took a combination of an antidepressant (AD and a normothymic (NT, NT and a neuroleptic (NL, AD, NT and NL. Those with BADII received monotherapy with AD or NL, a combination of AD + NT, AD + NL. The patients' status was clinically evaluated using a specially designed questionnaire and the MADRS and CGI psychometric scales at baseline and then at the end of 1, 2, 4, and 8 weeks of therapy.Results. The AD-containing regimens used to treat patients with BADI proved to be more effective; this therapy led to a more marked reduction in depressive symptoms (55.73% in the AD + NT-treated patients; 54.07% in the AD + NT + NL group versus 33.64% in the NT + NL-treated patients, a higher response to therapy, and a larger number of remissions by the end of the investigation (80.0, 72.7, and 33.3%, respectively. Moreover, the incidence of transient hypomanic symptoms did not significantly differ in these groups (20.0, 27.3, and 8.3%, respectively. The depressive patients with BADII generally responded better to different therapy regimens (the reduction in depressive symptoms was 52.08, 58.82, 58.40, and 53.98% in the AD, NL, AD + NT, and AD + NL groups; the remission index by the end of the investigation was 60.6, 92.9, 77.8, and 69.2%, respectively; these patients were seen to have less frequently symptoms of an antipole during their treatment (18.2, 7.1, 0.0, and 15.4%, respectively.Conclusion.

Higher FVC and FEV1 were related to better MN performance, but this did not reach statistical significance (FVC: B = 3.68, SE = 2.16, p = .09; FEV1: B = 4.92, SE = 2.64, p = .06. Higher FVC (B = 3.98, SE = 1.44, p = .01 and FEV1 (B = 4.79, SE = 1.75, p = .01 were associated with better ANT performance. The positive association between PF and BNT performance was marginally significant (FVC: B = 4.19, SE = 2.18, p = .06; FEV1: B = 3.51, SE = 2.66, p = .10. Discussion and Conclusion Better PF was associated with higher accuracy on sentence processing and naming-based lexical retrieval tasks, consistent with the conclusion that pulmonary function affects older adults’ language performance. Our findings support the emerging thesis that language changes in aging are influenced by health-related physiological and neural mechanisms (e.g., Albert et al., 2009; Cahana-Amitay et al., 2013. From a clinical perspective, these findings highlight the promise of targeting PF as an intervention for improving language abilities among the elderly.

  7. Tillage system affects microbiological properties of soil

    Delgado, A.; de Santiago, A.; Avilés, M.; Perea, F.

    2012-04-01

    Soil tillage significantly affects organic carbon accumulation, microbial biomass, and subsequently enzymatic activity in surface soil. Microbial activity in soil is a crucial parameter contributing to soil functioning, and thus a basic quality factor for soil. Since enzymes remain soil after excretion by living or disintegrating cells, shifts in their activities reflect long-term fluctuations in microbial biomass. In order to study the effects of no-till on biochemical and microbiological properties in comparison to conventional tillage in a representative soil from South Spain, an experiment was conducted since 1982 on the experimental farm of the Institute of Agriculture and Fisheries Research of Andalusia (IFAPA) in Carmona, SW Spain (37o24'07''N, 5o35'10''W). The soil at the experimental site was a very fine, montomorillonitic, thermic Chromic Haploxerert (Soil Survey Staff, 2010). A randomized complete block design involving three replications and the following two tillage treatments was performed: (i) Conventional tillage, which involved mouldboard plowing to a depth of 50 cm in the summer (once every three years), followed by field cultivation to a depth of 15 cm before sowing; crop residues being burnt, (ii) No tillage, which involved controlling weeds before sowing by spraying glyphosate and sowing directly into the crop residue from the previous year by using a planter with double-disk openers. For all tillage treatments, the crop rotation (annual crops) consisted of winter wheat, sunflower, and legumes (pea, chickpea, or faba bean, depending on the year), which were grown under rainfed conditions. Enzymatic activities (ß-glucosidase, dehydrogenase, aryl-sulphatase, acid phosphatase, and urease), soil microbial biomass by total viable cells number by acridine orange direct count, the density of cultivable groups of bacteria and fungi by dilution plating on semi-selective media, the physiological profiles of the microbial communities by BiologR, and the

    The Musical Emotional Bursts (MEB) consist of 80 brief musical executions expressing basic emotional states (happiness, sadness and fear) and neutrality. These musical bursts were designed to be the musical analog of the Montreal Affective Voices (MAV)-a set of brief non-verbal affective vocalizations portraying different basic emotions. The MEB consist of short (mean duration: 1.6 s) improvisations on a given emotion or of imitations of a given MAV stimulus, played on a violin (10 stimuli × 4 [3 emotions + neutral]), or a clarinet (10 stimuli × 4 [3 emotions + neutral]). The MEB arguably represent a primitive form of music emotional expression, just like the MAV represent a primitive form of vocal, non-linguistic emotional expression. To create the MEB, stimuli were recorded from 10 violinists and 10 clarinetists, and then evaluated by 60 participants. Participants evaluated 240 stimuli [30 stimuli × 4 (3 emotions + neutral) × 2 instruments] by performing either a forced-choice emotion categorization task, a valence rating task or an arousal rating task (20 subjects per task); 40 MAVs were also used in the same session with similar task instructions. Recognition accuracy of emotional categories expressed by the MEB (n:80) was lower than for the MAVs but still very high with an average percent correct recognition score of 80.4%. Highest recognition accuracies were obtained for happy clarinet (92.0%) and fearful or sad violin (88.0% each) MEB stimuli. The MEB can be used to compare the cerebral processing of emotional expressions in music and vocal communication, or used for testing affective perception in patients with communication problems.

  12. AFFECTIVE GUIDANCE OF INTELLIGENT AGENTS: How Emotion Controls Cognition.

    Clore, Gerald L; Palmer, Janet E

    2009-03-01

    Emotions and moods color cognition. In this article, we outline how emotions affect judgments and cognitive performance of human agents. We argue that affective influences are due, not to the affective reactions themselves, but to the information they carry about value, a potentially useful finding for creators of artificial agents. The kind of influence that occurs depends on the focus of the agent at the time. When making evaluative judgments, for example, agents may experience positive affect as a positive attitude toward a person or object. But when an agent focuses on a cognitive task, positive affect may act like performance feedback, with positive affect giving a green light to cognitive, relational processes. By contrast, negative affect tends to inhibit relational processing, resulting in a more perceptual, stimulus-specific processing. One result is that many textbook phenomena from cognitive psychology occur readily in happy moods, but are inhibited in sad moods. PMID:19255620

    Political communications in the form of unstructured text convey rich connotative meaning that can reveal underlying group social processes. Previous research has focused on sentiment analysis at the document level, but we extend this analysis to sub-document levels through a detailed analysis of affective relationships between entities extracted from a document. Instead of pure sentiment analysis, which is just positive or negative, we explore nuances of affective meaning in 22 affect categories. Our affect propagation algorithm automatically calculates and displays extracted affective relationships among entities in graphical form in our prototype (TEAMSTER), starting with seed lists of affect terms. Several useful metrics are defined to infer underlying group processes by aggregating affective relationships discovered in a text.

    Directory of Open Access Journals (Sweden)

    Marc Boumeester

    2014-10-01

    Full Text Available Underneath the turbulent surface of the ubiquitous media-scape lies an even more agile and aggressive set of relations. A central figure in this turmoil of desires seems to be the asignifying sign, which has a hybridising liaison with both the realm of the real virtual and the realm of the actualised. The main question is what does it want? This new materialistic, non-anthropocentric liberty of affect is creating an arena of strange attractors and other topological vector fields in which our own unconscious drive is as effective as that of the steel ball in a pinball machine. Could we isolate the intrinsic drive of the medium from its subservient position in the aesthetic, freeing its desire from the anthropocentric dominion? What does it Yen for? Perhaps this gap is not meant to be filled, as it is this yearning what it yearns for. The asignifying sign cannot be isolated, it is neither here nor there, yet it is conditionally omnipresent, it inhibits the gap, its desire is to affect.

  15. Older age may offset genetic influence on affect: The COMT polymorphism and affective well-being across the life span.

    The catechol-O-methyltransferase (COMT_Val158Met) genetic polymorphism has been linked to variation in affective well-being. Compared with Val carriers, Met carriers experience lower affective well-being. In parallel, research on aging and affective experience finds that younger adults experience poorer affective well-being than older adults. This study examined how COMT and age may interact to shape daily affective experience across the life span. Results suggest that Met (vs. Val) carriers experience lower levels of affective well-being in younger but not in older ages. These findings suggest that age-related improvements in emotional functioning may offset genetic vulnerabilities to negative affective experience. (PsycINFO Database Record PMID:27111524

  16. Theoretical and clinical overview of affective temperaments in mood disorders

    Full Text Available Temperaments are imperturbable variations of personality, traits and ways of reacting to the environment that characterize individuals and remain constant throughout several different situations. Temperaments usually play a central role in determining emotional reactions, therefore several temperamental models have attempted to establish the potential relationship between temperaments and affective disorders. According to Hagop Akiskal, affective temperaments are subclinical and subaffective trait-like manifestations of affective disorders. Unlike several models of temperament which were exclusively developed theoretically in order to describe healthy human functioning, later extrapolated to capture the pathological domains of mental and behavioral features, the current model of affective temperaments was developed on classical traditions and mainly based on the observation of subjects with mood disorders and their healthy first degree relatives. There is accumulating evidence concerning the development of affective temperaments based on their adaptive evolutionary characteristics and genetic background, and normative data from large national studies on general and healthy samples indicate their universal characteristics. Studies in affective patient populations indicate that the relationship between affective temperaments and affective illness is more complex than a simple extrapolation from psychopathology and mental health, and affective temperaments may represent a latent state of the staging model, playing a pathoplastic role in mood disorders determining their evolution, clinical features, main characteristics and outcome. A large body of data on affective temperaments has been published during the last decade, deserving a critical analysis presented in this overview.

  17. Clarifying the Relation Between Extraversion and Positive Affect.

    2015-10-01

    This article clarifies two sources of ambiguity surrounding the relation between extraversion and positive affect. First, positive affect is defined differently across major models of the structure of affect. Second, no previous research has examined potentially diverging associations of lower-order aspects of extraversion (i.e., assertiveness and enthusiasm) with positive affect. Australian (Study 1: N = 437, 78% female, Mage  = 20.41) and American (Study 2: N = 262, 39% female, Mage  = 33.86) participants completed multiple measures of extraversion and positive affect. Correlations were employed to examine relations among these measures. In both studies, extraversion was most clearly associated with positive affect as conceptualized within a major factor model of affect-specifically, as positive activation (Watson & Tellegen, 1985)-rather than the valence-based conceptualization of positive affect provided by a circumplex model of affect (Russell, 1980). This was also the case for the assertiveness and enthusiasm aspects of extraversion. Our findings clarify the nature of the positive affective component of extraversion, which is best described in terms of both positive valence and high activation. PMID:25234441

  18. Is positive affect in pregnancy protective of postpartum depression?

    2013-03-01

    Full Text Available OBJECTIVE: To investigate the predictive/protective role of negative affect/positive affect in late pregnancy on the outcome of postpartum depression. METHODS: A total of 491 pregnant women participated in the study. The participants were asked to fill out a series of questionnaires, which included the Profile of Mood States, the Beck Depression Inventory-II, psychosocial variables and socio-demographic characteristics and were asked to participate in a psychiatric interview. After delivery, 272 mothers participated again in the study and filled out a similar series of questionnaires. RESULTS: Negative affect was associated with more intense depressive symptomatology, more self-perceived stress, lower self-reported social support, lower quality of life and perception of having a more difficult infant. By contrast, positive affect was negatively associated with these variables. Negative affect in late pregnancy increased the likelihood of experiencing postpartum depression (DSM-IV/OR = 2.1, 95%CI = 1.3-3.4, p = .003; ICD-10/OR = 2.1, 95%CI = 1.5-3.0, p < .001, while positive affect increased the odds of not having this condition (DSM-IV/OR = 2.0, 95%CI = 1.5-2.7, p = .042. CONCLUSION: In pregnancy, negative affect was a predictor of postpartum depression, whereas positive affect showed a protective role. Future studies are required to explore whether psychotherapeutic strategies focusing on decreasing negative affect and enhancing positive affect in the last trimester of pregnancy can reduce the risk of postpartum depression.

  19. Rearing Room Affects the Non-dominant Chicken Cecum Microbiota, While Diet Affects the Dominant Microbiota

    2016-01-01

    The combined effect of environment and diet in shaping the gut microbiota remains largely unknown. This knowledge, however, is important for animal welfare and safe food production. For these reasons, we determined the effect of experimental units on the chicken cecum microbiota for a full factorial experiment where we tested the combined effect of room, diet, and antimicrobial treatment. By Illumina Deep sequencing of the 16S rRNA gene, we found that diet mainly affected the dominant microbiota, while the room as a proxy for environment had major effects on the non-dominant microbiota (p = 0.006, Kruskal–Wallis test). We, therefore, propose that the dominant and non-dominant microbiotas are shaped by different experimental units. These findings have implications both for our general understanding of the host-associated microbiota and for setting up experiments related to specific targeting of pathogens. PMID:26942187

  3. The neural basis of risky choice with affective outcomes.

    Directory of Open Access Journals (Sweden)

    Renata S Suter

    Full Text Available Both normative and many descriptive theories of decision making under risk are based on the notion that outcomes are weighted by their probability, with subsequent maximization of the (subjective expected outcome. Numerous investigations from psychology, economics, and neuroscience have produced evidence consistent with this notion. However, this research has typically investigated choices involving relatively affect-poor, monetary outcomes. We compared choice in relatively affect-poor, monetary lottery problems with choice in relatively affect-rich medical decision problems. Computational modeling of behavioral data and model-based neuroimaging analyses provide converging evidence for substantial differences in the respective decision mechanisms. Relative to affect-poor choices, affect-rich choices yielded a more strongly curved probability weighting function of cumulative prospect theory, thus signaling that the psychological impact of probabilities is strongly diminished for affect-rich outcomes. Examining task-dependent brain activation, we identified a region-by-condition interaction indicating qualitative differences of activation between affect-rich and affect-poor choices. Moreover, brain activation in regions that were more active during affect-poor choices (e.g., the supramarginal gyrus correlated with individual trial-by-trial decision weights, indicating that these regions reflect processing of probabilities. Formal reverse inference Neurosynth meta-analyses suggested that whereas affect-poor choices seem to be based on brain mechanisms for calculative processes, affect-rich choices are driven by the representation of outcomes' emotional value and autobiographical memories associated with them. These results provide evidence that the traditional notion of expectation maximization may not apply in the context of outcomes laden with affective responses, and that understanding the brain mechanisms of decision making requires the domain

    Affective decision-making is a strategic model of choice under risk and uncertainty where we posit two cognitive processes — the "rational" and the "emotional" process. Observed choice is the result of equilibirum in this intrapersonal game. As an example, we present applications of affective decision-making in insurance markets, where the risk perceptions of consumers are endogenous. We then derive the axiomatic foundation of affective decision making, and show that, although beliefs are end...

    Optimism-bias is inconsistent with the independence of decision weights and payoffs found in models of choice under risk, such as expected utility theory and prospect theory. Hence, to explain the evidence suggesting that agents are optimistically biased, we propose an alternative model of risky choice, affective decision-making, where decision weights -- which we label affective or perceived risk -- are endogenized. Affective decision making (ADM) is a strategic model of choice under risk, w...

    Maternal restrictive feeding behaviors have been associated with child weight status. The affective tone of mothers' statements intended to restrict their children's eating has not been examined. The objectives of this study were to describe the affective tone of mothers' restrictive feeding behaviors (positive or negative), and to test the association of child and mother characteristics with rates of Restriction with Positive Affect, Restriction with Negative Affect and Total Restriction. A total of 237 low-income child-mother dyads (mean child age 5.9 years) participated in a videotaped standardized laboratory eating protocol, during which mothers and children were both presented with large servings of cupcakes. A coding scheme was developed to count each restrictive statement with a positive affective tone and each restrictive statement with a negative affective tone. To establish reliability, 20% of videos were double-coded. Demographics and anthropometrics were obtained. Poisson regression models were used to test the association between characteristics of the child and mother with counts of Restriction with Positive Affect, Restriction with Negative Affect, and Total Restriction. Higher rates of Restriction with Positive Affect and Total Restriction were predicted by child obese weight status, and mother non-Hispanic white race/ethnicity. Higher rates of Restriction with Negative Affect were predicted by older child age, child obese weight status, mother non-Hispanic white race/ethnicity, and lower mother education level. In conclusion, in this study mothers of obese (vs. non-obese) children had higher rates of restriction in general, but particularly higher rates of Restriction with Negative Affect. Rather than being told not to restrict, mothers may need guidance on how to sensitively restrict their child's intake. Future studies should consider the contributions of maternal affect to children's responses to maternal restriction. PMID:27090342

    2013-12-01

    This study examined the influence of affect on interpersonal relationships in a dyadic communication context. The combination of speakers' affective states was considered, as compared to previous studies which considered only the individual's affective state. The independent variables, in a between-subjects design, were affective condition (positive vs. negative) and affective combination (similar vs. dissimilar). Participants (N = 86) took a test on creative thinking and were given false feedback. Then they had a 6-minute conversation and answered questions about their satisfaction with the conversation and their impressions of their partner. Results showed that the two-factor interactions were significant for satisfaction with the conversation and interpersonal impressions (social desirability) of the partner. The scores for these variables in the positive affect condition were higher than in the negative affect condition only when the affective combination was dissimilar. These results show that individual's affect could not predict conversational outcomes. The results were discussed in terms of incorrect inferences about the partner's affective state and imbalanced conversation activity. PMID:24505979

    Full Text Available Preterm birth places infants at increased risk for adverse developmental outcomes, with self- and affect regulation problems among the most important impairments. However, few studies have empirically examined maternal interpretation of infant affect in mothers of pre- and term infants. The current study examines how negative affect of mothers of preterm and term infants is associated with their interpretation of infant facial expressions.One hundred and sixty-eight mothers with their infants (64 term and 104 preterm participated. Seven days after birth, mothers completed the UWIST Mood Adjective Checklist (UMACL; Matthews, Jones, & Chamberlain, 1990 to assess maternal negative affect. During a home visit, six months after birth, mothers additionally completed a task developed to measure infant affect interpretation (Interpreting Facial Expressions of Emotions through Looking at Pictures task, IFEEL pictures task; Emde, Osofsky, & Butterfield, 1993.Mothers of preterm infants reported more negative affect than mothers of term infants. However, the relationship between infant birth status (i.e., term vs. preterm and maternal interpretation of infant facial expressions was moderated by the mother's own negative affectivity. Surprisingly, particularly mothers of term infants who also reported high levels of negative affect were found to interpret infant affect significantly more negatively.Prematurity itself does not seem to be a dominant factor in determining maternal infant affect interpretation, though maternal psychological negative mood does. Both theoretical and practical implications of the results are discussed.

    Full Text Available This discussion of affect and performance is based on early research for an artistic project called AffeXity exploring the use of augmented reality to embed affective choreographies in urban spaces. Affect is understood in terms of intensities and contingency, while performance is defined as a triangulation of bodily movement, emergence and shimmering. After a brief reflection on how technical development and artistic processes impact each other, the middle section of this article contains ‘an inventory of shimmers’ which are words from the processes of dance improvisation, video capture and editing. A methodological perspective is proposed. It is called affective sensibility.

    2014-08-01

    Full Text Available A good sense of humor has been implicated as a quality that could contribute to psychological well-being. The mechanisms through which sense of humor might operate include helping to reappraise threats, serving as a character strength, or facilitating happiness. The current research attempts to integrate these possibilities by examining whether a good sense of humor might operate globally by helping to maintain a more stable positive affect. Stable positive affect has been shown to facilitate more effective problem solving and to build resilience. However, not all humor is adaptive humor, so we also examine the roles that different styles of humor use might play. Individual differences in humor styles were used to predict stable levels of affect. Then, in a longitudinal design, humor styles and stable affect were used to predict subsequent resilience and psychological health. The results indicated that stable affect was related to resilience and psychological well-being, and that a sense of humor that involves self-enhancing humor, humor based on maintaining a humorous perspective about one’s experiences, was positively related to stable positive affect, negatively related to stable negative affect, and was mediated through stable affect in influencing resilience, well-being and distress. Thus, while a good sense of humor can lead to greater resilience and better psychological health, the current results, focusing on stable affect, find only self-enhancing humor provides reliable benefits.

  19. Instruments measuring blunted affect in schizophrenia: a systematic review.

    Directory of Open Access Journals (Sweden)

    Sanja Kilian

    Full Text Available Blunted affect, also referred to as emotional blunting, is a prominent symptom of schizophrenia. Patients with blunted affect have difficulty in expressing their emotions. The work of Abrams and Taylor and their development of the Rating Scale for Emotional Blunting in the late 1970's was an early indicator that blunted affect could indeed be assessed reliably. Since then, several new instruments assessing negative symptoms with subscales measuring blunted affect have been developed. In light of this, we aim to provide researchers and clinicians with a systematic review of the different instruments used to assess blunted affect by providing a comparison of the type, characteristics, administration and psychometric properties of these instruments. Studies reporting on the psychometric properties of instruments assessing blunted affect in patients with schizophrenia were included. Reviews and case studies were excluded. We reviewed 30 full-text articles and included 15 articles and 10 instruments in this systematic review. On average the instruments take 15-30 minutes to administer. We found that blunted affect items common across all instruments assess: gestures, facial expressions and vocal expressions. The CAINS Self-report Expression Subscale, had a low internal consistency score. This suggests that this sub-scale does not reliably assess patients' self-reported blunted affect symptoms and is likely due to the nature of blunted affect. Instruments correlated minimally with instruments measuring positive symptoms and more importantly with depression suggesting that the instruments distinguish between seemingly similar symptoms.

In this relationship, two moderators have been tested, relevance of the event and explanatory style. Seventy-three workers answered an attributional style questionnaire once (between-level data and also a daily questionnaire (within-level data about work events and affect for ten days (N = 730 observations.Multilevel analysis results showed that the influence of moderators in the relationship of appraisal-affect is asymmetric for positive and negative affect. At within-level there is a moderation of the importance attributed to the event for negative affect, but not for positive affect. In the same line, but in an inter-level relationship, the explanatory style has a moderator effect for negative affect when the event is appraised as important. Nevertheless, such an influence is not found for positive affect. The study provides new elements for a multilevel study of third variables in the daily dynamics of appraisal and affect.

  7. The neural mechanisms of pain-related affect and memory

    Institute of Scientific and Technical Information of China (English)

    2006-01-01

    The pain experience includes a sensory-discriminative and an emotional-affective components. The affective dimension refers to the unpleasantness or aversion of sensation. The great progress at the genetic, molecular, cellular, and systemic levels on the study of the sensory dimension of pain has been made over past four decades. However, "to consider only the sensory features of pain, and ignore its motivational and affective properties, is to look at only part of the problem and not even the most important part of that". A line of clinic observations indicate that the patients with chronic pain suffer from much more affective disturbance than pain itself. Obviously,physiological arousal and hypervigilance to pain cause negative affect, such as anxiety, anger, worry, aversion, even tendency of suicide,these negative affective states in turn enhance pain sensation. Today, more and more attention has been paid to the study on mechanisms underlying affective dimension of pain. In order to deepen and expand our understanding of the nature of pain, this review summarizes the main progress and recent findings from our laboratory regarding affective component of pain in neuroanatomy, neurophysiology, and cell biochemistry.

    2009-01-01

    Several studies have demonstrated that the outcome of chronic hepatitis C (CHC) infection is profoundly influenced by a variety of comorbidities. Many of these comorbidities have a significant influence on the response to antiviral therapy. These comorbidities negatively affect the course and outcome of liver disease, often reducing the chance of achieving a sustained virological response with PEGylated interferon and ribavirin treatments. Comorbidities affecting response to antiviral therapy reduce compliance and adherence to inadequate doses of therapy. The most important comorbidities affecting the course of CHC include hepatitis B virus coinfection, metabolic syndrome, and intestinal bacterial overgrowth.Comorbidities affecting the course and response to therapy include schistosomiasis, iron overload, alcohol abuse, and excessive smoking. Comorbidities affecting response to antiviral therapy include depression,anemia, cardiovascular disease, and renal failure.

  16. Consensus and stratification in the affective meaning of human sociality

    2014-01-01

    We investigate intrasocietal consensus and variation in affective meanings of concepts related to authority and community, two elementary forms of human sociality. Survey participants (n = 2,849) from different socioeconomic status (SES) groups in German society provided ratings of 909 social concepts along three basic dimensions of affective meaning. Results show widespread consensus on these meanings within society and demonstrate that a meaningful structure of socially shared knowledge emerges from organizing concepts according to their affective similarity. The consensus finding is further qualified by evidence for subtle systematic variation along SES differences. In relation to affectively neutral words, high-status individuals evaluate intimacy-related and socially desirable concepts as less positive and powerful than middle- or low-status individuals, while perceiving antisocial concepts as relatively more threatening. This systematic variation across SES groups suggests that the affective meaning of sociality is to some degree a function of social stratification. PMID:24843121

  17. Considering Affective Responses towards Environments for Enhancing Location Based Services

    Science.gov (United States)

    Huang, H.; Gartner, G.; Klettner, S.; Schmidt, M.

    2014-04-01

    A number of studies in the field of environmental psychology show that humans perceive and evaluate their surroundings affectively. Some places are experienced as unsafe, while some others as attractive and interesting. Experiences from daily life show that many of our daily behaviours and decision-making are often influenced by this kind of affective responses towards environments. Location based services (LBS) are often designed to assist and support people's behaviours and decision-making in space. In order to provide services with high usefulness (usability and utility), LBS should consider these kinds of affective responses towards environments. This paper reports on the results of a research project, which studies how people's affective responses towards environments can be modelled and acquired, as well as how LBS can benefit by considering these affective responses. As one of the most popular LBS applications, mobile pedestrian navigation systems are used as an example for illustration.

  18. Differential Predictability of Four Dimensions of Affect Intensity

    Science.gov (United States)

    Rubin, David C.; Hoyle, Rick H.; Leary, Mark R.

    2013-01-01

    Individual differences in affect intensity are typically assessed with the Affect Intensity Measure (AIM). Previous factor analyses suggest that the AIM is comprised of four weakly correlated factors: Positive Affectivity, Negative Reactivity, Negative Intensity and Positive Intensity or Serenity. However, little data exist to show whether its four factors relate to other measures differently enough to preclude use of the total scale score. The present study replicated the four-factor solution and found that subscales derived from the four factors correlated differently with criterion variables that assess personality domains, affective dispositions, and cognitive patterns that are associated with emotional reactions. The results show that use of the total AIM score can obscure relationships between specific features of affect intensity and other variables and suggest that researchers should examine the individual AIM subscales.

    Full Text Available Environmental events such as natural disasters may influence the public's affective reactions and decisions. Shortly after the 2004 Tsunami disaster we assessed how affect elicited by thinking about this disaster influenced risk perceptions and future time perspective in Swedish undergraduates not directly affected by the disaster. An experimental manipulation was used to increase the salience of affect associated with the disaster. In Study 1 we found that participants reminded about the tsunami had a sense that their life was more finite and included fewer opportunities than participants in the control condition (not reminded about the tsunami. In Study 2 we found similar effects for risk perceptions. In addition, we showed that manipulations of ease-of-thought influenced the extent to which affect influenced these risk perceptions, with greater ease of thoughts being associated with greater perceived risks.

    2015-12-01

    Full Text Available A series of studies investigated a proposed new individual difference characteristic or trait, facility for sustained positive affect, consisting of tendencies that allow individuals to maintain a high level of positive mood. Exploratory and confirmatory factor analyses resulted in the creation of a measure, the self-congruent and new activities (SANA scale which identified two core aspects of sustainable positive affect, engaging in self-congruent activities and engaging in new activities. A higher level of facility for sustainable affect, as operationalized by the SANA scale, was associated with maintenance of positive mood for a month, fewer symptoms of depression and anxiety, less negative affect, and more life satisfaction, relationship satisfaction, work satisfaction, mindfulness, personal expansion and growth, and emotional intelligence. The results provided initial evidence that facility to maintain positive affect may be an emotion-related individual difference characteristic.

  1. Affect labeling enhances exposure effectiveness for public speaking anxiety.

    Niles, Andrea N; Craske, Michelle G; Lieberman, Matthew D; Hur, Christopher

    2015-05-01

    Exposure is an effective treatment for anxiety but many patients do not respond fully. Affect labeling (labeling emotional experience) attenuates emotional responding. The current project examined whether affect labeling enhances exposure effectiveness in participants with public speaking anxiety. Participants were randomized to exposure with or without affect labeling. Physiological arousal and self-reported fear were assessed before and after exposure and compared between groups. Consistent with hypotheses, participants assigned to Affect Labeling, especially those who used more labels during exposure, showed greater reduction in physiological activation than Control participants. No effect was found for self-report measures. Also, greater emotion regulation deficits at baseline predicted more benefit in physiological arousal from exposure combined with affect labeling than exposure alone. The current research provides evidence that behavioral strategies that target prefrontal-amygdala circuitry can improve treatment effectiveness for anxiety and these effects are particularly pronounced for patients with the greatest deficits in emotion regulation.

    2016-07-01

    Studies on therapist factors have mostly focused on therapist traits rather than states such as affect. Research related to therapist affect has often looked at therapist baseline well-being or therapist reactions, but not both. Fifteen therapists and 51 clients rated pre- and postsession affect, as well as postsession working alliance and session quality, for 1,172 sessions of individual psychotherapy at a community clinic. Therapists' affect became more positive when clients were initially positive and when clients became more positive over the session, and became more negative when clients were initially negative and when clients became more negative over the session. Furthermore, when therapists were initially positive in affect and when therapists became more positive over the session, clients rated the session quality to be high. Conversely, when therapists were initially negative in affect and when therapists became more negative over the session, clients rated the session quality and working alliance low. On open-ended questions, therapists reported mood shifts in 67% of sessions (63% positive, 50% negative). Positive affect change was attributed to collaborating with the client, perceiving the client to be engaged, or being a good therapist. Negative affect change was attributed to having a difficult client, perceiving the client to be in distress, or being a poor therapist. Thus, therapist state affect at presession and change in affect across a session may independently contribute to the process and outcome of therapy sessions. The examination of within-therapist variables over the course of therapy may further our understanding of therapist factors. (PsycINFO Database Record PMID:27177026

  4. Network Diversity and Affect Dynamics: The Role of Personality Traits.

    Directory of Open Access Journals (Sweden)

    Aamena Alshamsi

    Full Text Available People divide their time unequally among their social contacts due to time constraints and varying strength of relationships. It was found that high diversity of social communication, dividing time more evenly among social contacts, is correlated with economic well-being both at macro and micro levels. Besides economic well-being, it is not clear how the diversity of social communication is also associated with the two components of individuals' subjective well-being, positive and negative affect. Specifically, positive affect and negative affect are two independent dimensions representing the experience (feeling of emotions. In this paper, we investigate the relationship between the daily diversity of social communication and dynamic affect states that people experience in their daily lives. We collected two high-resolution datasets that capture affect scores via daily experience sampling surveys and social interaction through wearable sensing technologies: sociometric badges for face-to-face interaction and smart phones for mobile phone calls. We found that communication diversity correlates with desirable affect states--e.g. an increase in the positive affect state or a decrease in the negative affect state--for some personality types, but correlates with undesirable affect states for others. For example, diversity in phone calls is experienced as good by introverts, but bad by extroverts; diversity in face-to-face interaction is experienced as good by people who tend to be positive by nature (trait but bad for people who tend to be not positive by nature. More broadly, the moderating effect of personality type on the relationship between diversity and affect was detected without any knowledge of the type of social tie or the content of communication. This provides further support for the power of unobtrusive sensing in understanding social dynamics, and in measuring the effect of potential interventions designed to improve well-being.

    2016-04-01

    Bad moods are considered "bad" not only because they may be aversive experiences in and of themselves, but also because they are associated with poorer psychosocial functioning and health. We propose that people differ in their negative affect valuation (NAV; the extent to which negative affective states are valued as pleasant, useful/helpful, appropriate, and meaningful experiences) and that affect-health links are moderated by NAV. These predictions were tested in a life span sample of 365 participants ranging from 14-88 years of age using reports of momentary negative affect and physical well-being (via experience sampling) and assessments of NAV and psychosocial and physical functioning (via computer-assisted personal interviews and behavioral measures of hand grip strength). Our study demonstrated that the more individuals valued negative affect, the less pronounced (and sometimes even nonexistent) were the associations between everyday experiences of negative affect and a variety of indicators of poorer psychosocial functioning (i.e., emotional health problems, social integration) and physical health (i.e., number of health conditions, health complaints, hand grip strength, momentary physical well-being). Exploratory analyses revealed that valuing positive affect was not associated with the analogous moderating effects as NAV. These findings suggest that it may be particularly important to consider NAV in models of affect-health links. (PsycINFO Database Record PMID:26571077

  7. Unintentionality of affective attention across visual processing stages

    Directory of Open Access Journals (Sweden)

    Andero eUusberg

    2013-12-01

    Full Text Available Affective attention involves bottom-up perceptual selection that prioritizes motivationally significant stimuli. To clarify the extent to which this process is automatic, we investigated the dependence of affective attention on the intention to process emotional meaning. Affective attention was manipulated by presenting IAPS images with variable arousal and intentionality by requiring participants to make affective and non-affective evaluations. Polytomous rather than binary decisions were required from the participants in order to elicit relatively deep emotional processing. The temporal dynamics of prioritized processing were assessed using Early Posterior Negativity (EPN, 175-300 ms as well as P3-like (P3, 300 – 500 ms and Slow Wave (SW, 500 – 1500 ms portions of the Late Positive Potential. All analysed components were differentially sensitive to stimulus categories suggesting that they indeed reflect distinct stages of motivational significance encoding. The intention to perceive emotional meaning had no effect on EPN, an additive effect on P3, and an interactive effect on SW. We concluded that affective attention went from completely unintentional during the EPN to partially unintentional during P3 and SW where top-down signals, respectively, complemented and modulated bottom-up differences in stimulus prioritization. The findings were interpreted in light of two-stage models of visual perception by associating the EPN with large-capacity initial relevance detection and the P3 as well as SW with capacity-limited consolidation and elaboration of affective stimuli.

  8. Mind Invasion: Situated Affectivity and the Corporate Life Hack

    Slaby, Jan

    2016-01-01

    In view of the philosophical problems that vex the debate on situated affectivity, it can seem wise to focus on simple cases. Accordingly, theorists often single out scenarios in which an individual employs a device in order to enhance their emotional experience, or to achieve new kinds of experience altogether, such as playing an instrument, going to the movies, or sporting a fancy handbag. I argue that this narrow focus on cases that fit a “user/resource model” tends to channel attention away from more complex and also more problematic instances of situated affectivity. Among these are scenarios in which a social domain draws individuals into certain modes of affective interaction, often by way of attunement and habituation to affective styles and interaction patterns that are normative in the domain in question. This can lead to a phenomenon that is not so much “mind extension” than “mind invasion”: affectivity is dynamically framed and modulated from without, often contrary to the prior orientations of the individuals in question. As an example, I discuss affective patterns prevalent in today's corporate workplace. I claim that workplace affect sometimes contributes to what is effectively a “hack” of employees' subjectivity.

Accordingly, theorists often single out scenarios in which an individual employs a device in order to enhance their emotional experience, or to achieve new kinds of experience altogether, such as playing an instrument, going to the movies, or sporting a fancy handbag. I argue that this narrow focus on cases that fit a "user/resource model" tends to channel attention away from more complex and also more problematic instances of situated affectivity. Among these are scenarios in which a social domain draws individuals into certain modes of affective interaction, often by way of attunement and habituation to affective styles and interaction patterns that are normative in the domain in question. This can lead to a phenomenon that is not so much "mind extension" than "mind invasion": affectivity is dynamically framed and modulated from without, often contrary to the prior orientations of the individuals in question. As an example, I discuss affective patterns prevalent in today's corporate workplace. I claim that workplace affect sometimes contributes to what is effectively a "hack" of employees' subjectivity.

    Full Text Available The purpose of this study was to expand our understanding of the range of negative affect associated with reported problems with everyday functions and activities, measured by the cognitive failures questionnaire (CFQ. Evidence from previous research indicates that individuals meeting criteria for mood disorders, such as major depression or seasonal affective disorder, experience cognitive deficits in memory and attention that can lead to problems with everyday activities reported in the CFQ. The Positive and Negative Affect Scale (PANAS was used to assess potential correlations with a wider range of negative emotions. Findings for a sample of 129 college students revealed that negative affective experiences were significantly correlated with failures of memory and attention on the CFQ (fear = .41, hostility = .38, sadness = .28, and guilt = .43. Conversely, positive affect was negatively correlated with distractibility (r=−.21. Additional affective scales on the PANAS (e.g., shyness and fatigue were also associated with higher reports of cognitive failures. The results provide converging evidence of a relationship between negative affective experiences and reported frequency of problems on the cognitive failures questionnaire.

    Full Text Available The paper delineates a study of executive functions (EFs, construed as procedural working memory (WM, from a motivational perspective. Since WM theories and motivation theories are both concerned with purposive activity, the role of implicit evaluations (affects observed in goal pursuit can be anticipated to arise also in the context of cognitive control, e.g., during the performance of the Stroop task. The role of positive and negative affect in goal pursuit consists in controlling attention resources according to the goal and situational requirements. Positive affect serves to maintain goals and means in the scope of attention (EF1, whereas negative affect activates the inhibition of non-functional contents, e.g., distractors and irrelevant objects (resulting in attention disengagement; EF2. Adaptation to conflict proceeds via sequential triggering of negative and positive affect (EF3. Moreover, it was demonstrated that the focus on action or reflection changes the scope of contents subjected to implicit (affective control. Therefore, I suggest that the motivational system, to a large extent, plays the role of the Central Executive. The paper opens a discussion and proposes studies on affective mechanisms of cognitive control.

  13. Manufacturing Panic: Affect and Contagion through Weather News

    Full Text Available Given the intense emphasis on weather forecast news in the US media, this study will approach the news as “affective mediated phenomenon” in a search for the problems which motivates practices or depletions. Through the ontological readings of ‘affect’ in the recent literature on “affective turn”, it aims to open up a new platform to analyze the fundamentals of relationality within televised and online weather forecasting and their extension in the society. I will focus on the Facebook group “Stop the Weather Channel from naming Winter Storms” which was created as a resistance to the everyday production of affective threat-values of The Weather Channel (TWC’s naming of storms. I will analyze both the shared images from TV (via YouTube videos and user comments on them utilizing Brian Massumi’s notion of “affective facts” and Anna Gibbs’ notion of “affect-contagion”. I will argue that, weather news produces affective registers which trigger continuous processes of re-making of the bodies as if it is a real situation. Thus, through the affective reality of anticipated alternatives created by weather news, performative threat-value of the thought-signs increases. I will show instances of mimetic relations between the bodies as anxiety formation through the portrayals of practices of emptying supermarkets, showing “signs” through visualized narration of cloud movements, and live-connections to the “scene”. Media’s emphasis on faces, values and rhythms of resonance with the portrayed bodies in anxiety from the previous storms works as an activation contour of affect-contagion. Weather news produces a form of subjectivity through affective mediations of technical means which amplifies audiences.

  14. Enhancing animal welfare by creating opportunities for positive affective engagement.

    In line with an increasing emphasis on promoting positive welfare states in animals, this review extends previous accounts of how recent affective neuroscience observations may be used to identify and then to encourage animals to engage in reward-motivated behaviours. The terms affective states or affects are used to mean the subjective experiences, feelings or emotions that may motivate animals to behave in goal-directed ways and which may accompany success or failure to achieve those goals. These motivational affects may be positive, experienced as rewarding or pleasurable, or negative, experienced as aversive or punishing. There are two overall types: homeostasis-related negative affects that reflect an animal's internal physiological state, and situation-related positive or negative affects that reflect an animal's perception of its external circumstances. The major emphasis is on positive situation-related affects, in particular those that are potentially associated with exploration, feeding and animal-to-animal affiliative behaviours. The review introduces the new concept of positive affective engagement which represents the experience animals may have when they actively respond to motivations to engage in rewarding behaviours, and it incorporates all associated affects that are positive. For example, it would represent a state of engaged aliveness that may attend an animal's goal-directed, energised exploration of and interactions with a stimulus-rich environment. It also represents some states of equally energised, highly focused predatory stalking by carnivores or the focused and engaged foraging by herbivores when they are grazing in natural environments where food sources are abundant. Positive affective engagement may also be anticipated to accompany some aspects of reciprocated affiliative interactions between animals, the dedicated maternal nurturing and care of young, the joyfulness of rough-and-tumble play, and the eroticism and orgasmic pleasures

  15. Perception of Affective Body Movements in HRI Across Age Groups

    robots and the signals they produce. In this paper we focus on affective connotations of body movements and investigate how the perception of body movements of robots is related to age. Inspired by a study from Japan, we introduce culture as a variable in the experiment and discuss the difficulties of...... cross-cultural comparisons. The results show that there are certain age-related differences in the perception of affective body movements, but not as strong as in the original study. A follow up experiment puts the affective body movements into context and shows that recognition rates deteriorate for...

  16. Accounting for Human Polymorphisms Predicted to Affect Protein Function

    A major interest in human genetics is to determine whether a nonsynonymous single-base nucleotide polymorphism (nsSNP) in a gene affects its protein product and, consequently, impacts the carrier's health. We used the SIFT (Sorting Intolerant From Tolerant) program to predict that 25% of 3084 nsSNPs from dbSNP, a public SNP database, would affect protein function. Some of the nsSNPs predicted to affect function were variants known to be associated with disease. Others were artifacts of SNP di...

    The advanced artificial intelligence of the system includes three modules, namely Probabilistic Love Assembly (PLA, based on the psychology of love, Artificial Endocrine System (AES, based on the physiology of love, and Affective State Transition (AST, based on emotions. The PLA module employs a Bayesian network to incorporate psychological parameters of affection in the robot. The AES module employs artificial emotional and biological hormones via a Dynamic Bayesian Network (DBN. The AST module uses a novel transition method for handling affective states of the robot. These three modules work together to manage emotional behaviours of the robot.

  19. Course and cognitive outcome in major affective disorder.

    Knowledge of the course and outcome of major affective illness has clinical as well as theoretical implications. In understanding the pathophysiology of the major affective disorders, an essential question in the interplay between biological, psychological and social factors is whether the individual is changed biologically by experiencing an affective episode or not. A biological change may be reflected in a changed risk of experiencing new episodes and changed chances of recovery from these episodes for the individual, and may possibly also be reflected in persisting altered cognitive function as an expression of brain function affected during a longer period. Previous studies of the course of affective episodes are flawed by a number of drawbacks such as various definitions of recovery and recurrence, various kinds of bias and confounders, low statistical power, and statistical analyses conducted without survival models and without paying attention to diagnostic instability or the individual heterogeneity of the course of episodes. Totally, these drawbacks and pitfalls affect the results of previous studies in unpredictable ways and make it hazardous to draw conclusions about the effect of prior affective episodes on the subsequent course of unipolar and bipolar disorder. The present thesis avoided most of these pitfalls or adjusted for them in analyses of hospital data from the Danish Psychiatric Central Register, collected nationwide from 1971 to 1993. Hospitalisation was used as an expression of an affective episode. On average, a progressive course with increasing risk of recurrence with every new episode was found for unipolar and bipolar affective disorders. Initially, the two types of disorders followed markedly different courses, but later in the course of the illness the risk of recurrence was the same for the two disorders. However, analyses with frailty models revealed that for unipolar men, this progressive course was due to a subgroup of patients

  20. Study of individual and group affective processes in the crew of a simulated mission to Mars: Positive affectivity as a valuable indicator of changes in the crew affectivity

    The success of a long-duration space mission depends on various technical demands as well as on the psychological (cognitive, affective, and motivational) adaptation of crewmembers and the quality of interactions within the crew. We examined the ways crewmembers of a 520-day simulated spaceflight to Mars (held in the Institute for Biomedical Problems, in Moscow) experienced and regulated their moods and emotions. Results show that crewmembers experienced predominantly positive emotions throughout their 520-day isolation and the changes in mood of the crewmembers were asynchronous and balanced. The study suggests that during the simulation, crewmembers experienced and regulated their emotions differently than they usually do in their everyday life. In isolation, crewmembers preferred to suppress and neutralize their negative emotions and express overtly only emotions with positive valence. Although the affective processes were almost invariable throughout the simulation, two periods of time when the level of positive emotions declined were identified. Regarding the findings, the paper suggests that changes in positive affectivity could be a more valuable indicator of human experience in demanding but professional environments than changes in negative affectivity. Finally, the paper discusses the phenomenology of emotions during a real space mission.
