Which factors influence a human being’s ability to develop new perspectives and be creative? This ability is pivotal for any context in which new cognitions are required, such as innovative endeavors in science and art, or psychotherapeutic settings. In this article, we seek to bring together two research programs investigating the generation of creative options: On the one hand, research on option generation in the decision-making literature and, on the other hand, cognitive and clinical creativity research. Previous decision-making research has largely neglected the topic of generating creative options. Experiments typically provided participants with a clear set of options to choose from, but everyday life situations are less structured and allow countless ways to react. Before choosing an option, agents have to self-generate a set of options to choose from. Such option generation processes have only recently moved to the center of attention. The present study examines the creative quality of self-generated options in daily life situations. A student sample (N = 48) generated options for action in 70 briefly described everyday life scenarios. We rated the quality of the options on three dimensions of creativity- originality, feasibility, and divergence -and linked these qualities to option generation fluency (speed and number of generated options), situational features like the familiarity and the affective valence of the situation in which the options were generated, and trait measures of cognitive performance. We found that when situations were familiar to the participant, greater negative affective valence of the situation was associated with more originality and divergence of generated options. We also found that a higher option generation fluency was associated with a greater maximal originality of options. We complete our article with a joint research agenda for researchers in the decision-making field focusing on option generation and, on the other hand
How does power manifest itself in everyday life? Using experience-sampling methodology, we investigated the prevalence, sources, and correlates of power in people’s natural environments. Participants experienced power-relevant situations regularly, though not frequently. High power was not restricted to a limited few: almost half of the sample reported experiencing high-power positions. Positional power and subjective feelings of power were strongly related but had unique relations with several individual difference measures and independent effects on participants’ affect, cognition, and interpersonal relations. Subjective feelings of power resulted more from within-participant situational fluctuation, such as the social roles participants held at different times, than from stable differences between people. Our data supported some theoretical predictions about power’s effects on affect, cognition, and interpersonal relations, but qualified others, particularly highlighting the role of responsibility in power’s effects. Although the power literature has focused on high power, we found stronger effects of low power than high power. PMID:27551069

Despite decades of research establishing the causes and consequences of emotions in the laboratory, we know surprisingly little about emotions in everyday life. We developed a smartphone application that monitored real-time emotions of an exceptionally large (N = 11,000+) and heterogeneous participants sample. People's everyday life seems profoundly emotional: participants experienced at least one emotion 90% of the time. The most frequent emotion was joy, followed by love and anxiety. People experienced positive emotions 2.5 times more often than negative emotions, but also experienced positive and negative emotions simultaneously relatively frequently. We also characterized the interconnections between people's emotions using network analysis. This novel approach to emotion research suggests that specific emotions can fall into the following categories 1) connector emotions (e.g., joy), which stimulate same valence emotions while inhibiting opposite valence emotions, 2) provincial emotions (e.g., gratitude), which stimulate same valence emotions only, or 3) distal emotions (e.g., embarrassment), which have little interaction with other emotions and are typically experienced in isolation. Providing both basic foundations and novel tools to the study of emotions in everyday life, these findings demonstrate that emotions are ubiquitous to life and can exist together and distinctly, which has important implications for both emotional interventions and theory.

This study focused on the use of math in everyday life (the propensity to recognize and solve quantitative issues in real life situations). Data from a Dutch nation-wide research on math among adults (N = 521) were used to investigate the question whether math anxiety and perceived math competence mediated the relationship between math skills and use of math in everyday life, taken gender differences into account. Results showed that women reported higher math anxiety, lower perceived math competence, and lower use of math in everyday life, compared to men. Women's skills were estimated at a lower level than men's. For both women and men, higher skills were associated with higher perceived math competence, which in turn was associated with more use of math in everyday life. Only for women, math anxiety also mediated the relation between math skills and use of math in everyday life. PMID:27148122

Several meta-analyses have investigated the association between physical activity and affective states and have found evidence suggesting that exercise exerts a positive effect on affective state. However, in this field of research, most studies have conducted between-subject analyses. Nonetheless, there is more and more interest in the within-subject associations between physical activity and momentary affective states in everyday life. This position statement pertains to this up-and-coming field of research and provides methodological recommendations for further studies. The paper is divided into three parts: first, we summarize and evaluate three methodological requirements necessary for the proper evaluation of within-subject associations between physical activity and momentary affective states in everyday life. We propose that the following issues should be considered: (a) to address the dynamic nature of such relationships, repeated assessments are necessary; (b) as activities performed in everyday life are mostly spontaneous and unconscious, an objective assessment of physical activity is useful; (c) given that recall of affective states is often affected by systematic distortions, real-time assessment is preferable. In sum, we suggest the use of ambulatory assessment techniques, and more specifically the combination of accelerometer-assessment of physical activity with an electronic diary assessment of the momentary affective state and additional context information. Second, we summarize 22 empirical studies published between 1980 and 2012 using ambulatory assessment to investigate within-subject associations between momentary affective states and physical activity in everyday life. Generally, the literature overview detects a positive association, which appears stronger among those studies that were of high methodological quality. Third, we propose the use of ambulatory assessment intervention (AAIs) strategies to change people’s behavior and to enable

Cortisol, the major physiological end product of the hypothalamic-pituitary-adrenal axis, is usually associated with stress and negative affect. However, a new body of research highlights the complex, adaptive significance of elevated cortisol within individuals in everyday life. Whereas most studies do not have the power to test the dynamic transactions between cortisol and affect within a person throughout the entire waking day, we employed an intensive study protocol analyzing hourly diary reports of affect in relation to hourly salivary cortisol samples among 24 healthy adults from morning to bedtime, across 2 consecutive weekdays (N = 862 total samples). Utilizing multileveling modeling and focusing on within-person effects, we examined whether momentary increases in cortisol could be mood protective, or energy enhancing, in everyday life, supporting the cortisol boost hypothesis. Results revealed no significant associations between cortisol and current affective state; however, within-person increases in cortisol were significantly associated with subsequent rises in activeness, alertness, and relaxation, and trend-level reductions in stress and nervousness. This study adds to growing evidence that cortisol plays a positive role in regulating affect in everyday life. (PsycINFO Database Record

Human behavior understanding in everyday life is promising but not established research field. Our project named 'open life matrix' is focused on this field. In these years, many sensor houses and robotic room projects have been studied and sensing and network technology have been established. However, still we have problems to realize everyday life support information systems and services. There are two major problems. The first one is data representation and computational modeling problem in everyday life. The second one is that we don't have a good way to realize valuable services from research outcomes. We propose a challenge to solve these problems by a scheme for accumulating common data set and probabilistic causal modeling during everyday life services.

Background Even though respiratory symptoms are common in the adult population, there is limited research describing their impact on everyday life and association with health care consumption. Aim The main objective of this population-based study was to estimate and compare the prevalence of respiratory symptoms among adults in Finland, Estonia, and Sweden in relation to health care consumption and to identify factors influencing health care consumption. A secondary aim was to assess to which extent the presence of respiratory symptoms affect everyday life. Method In the population-based FinEsS studies consisting of random samples of subjects aged 20 to 69 years from Finland (n=1,337), Estonia (n=1,346), and Sweden (n=1,953), data on demographics, respiratory health, and health care consumption were collected by structured interviews. Prevalence was compared and multiple logistic regression analyses were performed. Results Respiratory symptoms were significantly more common in Finland (66.0%) and Estonia (65.2%) than in Sweden (54.1%). Among subjects with respiratory symptoms, the proportion reporting outpatient care during the past year was fairly similar in the three countries, while specialist consultations were more common in Finland (19.1%), and hospitalisations more common in Estonia (15.0%). Finnish and Estonian residency, female sex, and BMI>25 increased the risk for outpatient care consumption. Wheeze and attacks of shortness of breath in the past 12 months, recurrent sputum production, and cough were associated with an increased risk for health care consumption. Increasing number of respiratory symptoms increased the risk for consuming health care. A larger proportion of subjects in Estonia and Sweden experienced their everyday life being affected by respiratory symptoms compared with subjects in Finland. Conclusion Respiratory symptoms are common in Finland, Estonia, and Sweden and contribute to a negative impact on everyday life as well as increased

Emotion in daily life may be associated with transient myocardial ischemia, ventricular tachycardia and impaired autonomic function in cardiac patients, but the precise temporal sequence is unclear. Eighty-eight patients with suspected coronary artery disease underwent 24-h electrocardiographic monitoring, and affect was measured with the Day Reconstruction Method. Thirteen patients (15%) experienced one or more episodes of ST depression or ventricular tachycardia, nine of whom provided concurrent mood data. Mood and heart rate variability were analyzed for the 15 min before, during, and 15 min after each ST depression/ventricular tachycardia episode, and were compared with control periods not associated with cardiac dysfunction. Patients reported more negative mood in the 15 min preceding cardiac dysfunction compared with control periods (P = 0.02). Heart rate increased in the 5 min before cardiac dysfunction (P = 0.005), whereas low frequency heart rate variability was reduced at onset but not before cardiac dysfunction (P = 0.007). There were not changes in high frequency heart rate variability. This small study indicates that emotional state may contribute to vulnerability of cardiac dysfunction in everyday life.

Most people believe that time seems to pass more quickly as they age. Building on assumptions of socioemotional selectivity theory, we investigated whether awareness that one's future lifetime is limited is associated with one's experience of time during everyday activities across adulthood in 3 studies. In the first 2 studies (Study 1: N = 608; Study 2: N = 398), participants completed a web-based version of the day reconstruction method. In Study 3 (N = 392) participants took part in a newly developed tomorrow construction method, a web-based experimental method for assessing everyday life plans. Results confirmed that older adults' subjective interpretation of everyday episodes is that these episodes pass more quickly compared with younger adults. The subjective acceleration of time experience in old age was more pronounced during productive activities than during regenerative-consumptive activities. The age differences were partly related to limited time remaining in life. In addition, subjective acceleration of time experience was associated with positive evaluations of everyday activities. Findings suggest that subjective acceleration of time in older adults' daily lives reflects an adaptation to limitations in time remaining in life. (PsycINFO Database Record

The objective of this study was to test a time-efficient screening instrument to assess clinically relevant and everyday-life (e.g., economic, political, personal) anxieties. Furthermore, factors influencing these anxieties, correlations between clinical and everyday anxieties and, for the first time, anxiety during different stages of life were assessed in a representative sample of the general population (N = 2229). Around 30% of the respondents manifested at least one disorder-specific key symptom within 1 year (women > men), 8% reported severe anxiety symptoms. Two thirds of respondents reported minor everyday anxieties and 5% were strongly impaired, whereby persons with severe clinical symptoms were more frequently affected. A variety of potential influencing factors could be identified. These include, in addition to socioeconomic status, gender, general health, risk-taking, and leisure behavior, also some up to now little investigated possible protective factors, such as everyday-life mental activity. The observed effects are rather small, which, however, given the heterogeneity of the general population seems plausible. Although the correlative design of the study does not allow direct causal conclusions, it can, however, serve as a starting point for experimental intervention studies in the future. Together with time series from repeated representative surveys, we expect these data to provide a better understanding of the processes that underlie everyday-life and clinical anxieties.

Despite the dire circumstances of Jews under Nazi occupation, individuals continued to persevere in their efforts to maintain patterns of everyday life. An understanding of daily routines may help us comprehend the reality of the Holocaust, but it may also contribute to the trivialization and banalization of the topic. To counter this danger, the methodology proposed in this article asserts that the individual's struggle reveals another perspective on the state of mind and the social order of various strata of Jewish society under Nazi occupation. Invoking the concepts of Berger and Luckmann in their analysis of understanding the knowledge of everyday life, this article examines the perception of reality of intellectuals in the ghetto.

There are only a few studies about how primary school students engage in socio-scientific discussions. This study aims to add to this field of research by focusing on how 9-10-year-olds in Sweden and England handle climate change as a complex environmental socio-scientific issue (SSI), within the context of their own lives and in relation to society at large. It focuses on how different interpretative repertoires were used by the students in discussions to legitimise or question their everyday lifestyles. They discussed four possible options that a government might consider to help reduce carbon dioxide production. Six main repertoires were identified: Everyday life, Self-Interest, Environment, Science and Technology, Society and Justice. The Everyday life repertoire was used when students related their discussion to their everyday lifestyles. Science and technology-related solutions were offered to maintain or improve things, but these were sometimes rather unrealistic. Arguments related to environment and health frequently appeared to have a superior status compared to the others. Findings also highlighted how conflicts between the students were actually productive by bringing in several perspectives to negotiate the solutions. These primary school students were, therefore, able to discuss and negotiate a complex real-world SSI. Students positioned themselves as active contributors to society, using their life experiences and limited knowledge to understand the problems that affected their everyday lives. Honing these skills within a school science community of practice could facilitate primary students' engagement with SSIs and empower them as citizens.

This paper presents a case study exploring an older woman's perspective on the quality of her life with dementia. The case study establishes the importance of coherence across the life course in understanding how she evaluates her changed situation in the present compared to the past. The metaphoric description of moving from 'up there' to 'down here' represents the perceived struggle to maintain a sense of worth despite a marginalised social position. Being able to define self and social identity in ways that preserve a sense of social status is important to find meaning in everyday life. Finding meaning involves looking backwards to sustain continuity with the past and looking forwards to maintain momentum and keep going. A narrative framework is valuable in showing that quality of life is a dimension of meaning associated with maintaining a sense of social worth.

Community-based day care that provides rehabilitation (DCR) targets elderly people with physical disabilities. The goal of these programmes is mainly to improve physical ability in order to enable participants to remain in their ordinary homes. Knowledge of the outcomes of DCR is limited as well as knowledge of what it is that makes a difference for the individual. The aim of this study was to describe what changes in everyday life elderly persons experienced after discharge from a community-based day care rehabilitation centre and to give possible explanations for these changes. Fifteen elderly people were interviewed after that they had been discharged from DCR. A narrative approach was used for analysing the interview data. Four case stories constitute the findings, each of them with unique descriptions of changes in everyday life as well as possible explanations for these changes. The first case story described resumption of daily activities that made the days more eventful and meaningful. The second described how everyday life became an arena for exercising, which create confidence for the future. The third described how an increased sense of certainty and security in the movements led to an increased appetite for life. Finally, the fourth case story described both the stay at the DCR centre and the promise of a new period there as uplifting that made the days easier. Concerning possible explanations for these changes, the findings indicate that it was a combination of several events that together contributed to the changes. Examples were physical training, counselling about how to live in an active and healthy lifestyle, and socialisation with other patients in formal as well as in informal sessions. PMID:21423596

This study tested crucial components of Gray's reinforcement sensitivity theory that have generally been overlooked in the literature. We tested whether the perceived amount of reward moderates the behavioral approach system (BAS) and the importance of reward mediates BAS in the prediction of job satisfaction and organizational commitment. Results from 514 participants employed in part-time and full-time jobs provided support for our model, such that the indirect effect of BAS through the importance of reward was strongest when reward was provided. This model advances our understanding of reinforcement sensitivity theory and offers a solid foundation for predicting outcomes in everyday life.

It has been argued that executive tests should capture central aspects of executive functions in everyday life such as initiating and monitoring parallel actions in low-structured environments (so-called multitasking; see Burgess, 2000). We present a cooking task in order to assess executive function impairments in brain-damaged patients, which focuses on a central feature of multitasking, the interleaving of tasks (Burgess, 2000). Behavioural performance of 21 brain-damaged patients (stroke, traumatic brain injury) and of a group of matched controls was analysed on the basis of a standardized protocol. In comparison to controls, the patients explored less, were less successful in monitoring their actions and corrected errors less efficiently. Interleaving of actions was observed less frequently in patients, with respect to both cooking itself as well as to subordinate goals (e.g., cleaning up). Interleaving proved efficient, as it was associated with less time to complete the task. Patients' scores in the cooking task correlated with performance in both the Behavioural Assessment of the Dysexecutive Syndrome (BADS) Zoo Map Test and the BADS Six Elements Test, but not with tests of attention, verbal memory, or figural fluency, thus demonstrating convergent and discriminant validity. In summary, our task demonstrates that cooking can provide a valid testing ground for assessing a central aspect of everyday multitasking demands, namely, the interleaving of actions.

In a diary study of interpersonal affect transfer, 41 participants reported on decisions involving other people over 3 weeks. Reported anxiety and excitement were reliably related to the perceived anxiety and excitement of another person who was present during decision making. Risk and importance appraisals partially mediated effects of other's anxiety on own anxiety as predicted by social appraisal theory. However, other's emotion remained a significant independent predictor of own emotion after controlling for appraisals, supporting the additional impact of more direct forms of affect transfer such as emotion contagion. Significant affect-transfer effects remained even after controlling for participants' perceptions of the other's emotion in addition to all measured appraisals, confirming that affect transfer does not require explicit registration of someone else's feelings. This research provides some of the clearest evidence for the operation of both social appraisal and automatic affect transfer in everyday social life.
This article explores the possibility of the continuation of everyday life in occupied Europe through a case study of the lives of twenty-five adolescent girls and young women living in Latvia between 1939 and 1944. Late adolescence is the period in which young women are struggling to establish some degree of independence, especially through leaving the parental home and entering the labour market. These transitions are the conventional markers of adulthood in modern societies. The article explores how occupation by the Soviet Union and the Third Reich affected daily life and the speed and nature of the transition to adulthood.

Technology increasingly influences the everyday lives of most people, and the ability to manage technology can be seen as a prerequisite for participation in everyday occupations. However, knowledge of the ability and skills required for management of technology is sparse. This study aimed to validate a new observation-based assessment, the Management of Everyday Technology Assessment (META). The META has been developed to assess the ability to manage technology in everyday life. A sample of 116 older adults with and without cognitive impairment were observed and interviewed by the use of the META when managing their everyday technology at home. The results indicate that the META demonstrates acceptable person response validity and technology goodness-of-fit. Additionally, the META can separate individuals with higher ability from individuals with lower ability to manage everyday technology. The META can be seen as a complement to existing ADL assessment techniques and is planned to be used in both research and practice.

Everyday life consists of daily activities that are taken for granted. It forms the foundation for human efforts and contains elements of both comfort and boredom. Because everyday life escapes no one, life in a psychiatric ward will become ordinary while staying there. This study aims to explore everyday life in psychiatric inpatient care based on patients’ experiences. We individually interviewed 16 participants with experiences of psychiatric inpatient care and analysed the data in accordance with the methods of grounded theory. Data collection and analysis continued in parallel in accordance with the method. Our results showed that everyday life is linked to the core category quality of interactions influences everyday life, and three constructed categories—staff makes the difference, looking for shelter in a stigmatizing environment, and facing a confusing care content—were related to the core category. Our results highlight the importance of ordinary relationships between staff and patients in psychiatric inpatient care. These results can be used to develop nursing interventions to improve psychiatric inpatient care and might also be used as a basis for reflective dialogues among staff. PMID:26806313

WHAT IS KNOWN ON THE SUBJECT?: Psychiatric inpatient care has been described by both ward staff and patients as being demanding and disorganized, lacking opportunities for quality interactions in everyday life through joint activities. Qualitative research on interprofessional teams' perspectives on everyday life processes in psychiatric inpatient care is lacking. WHAT THIS PAPER ADDS TO EXISTING KNOWLEDGE?: Staff have ideals about care and collaboration, but the obstacles they face in everyday life, such as a poor environment, power asymmetry, lacking structure and the demands of managing chaos, mean that they appear to resign and shift focus from the patients' best interests to self-survival. Different professions in general describe the same obstacles in everyday life on the wards but there are also profession-specific perspectives on distancing and feelings of abandonment. To our knowledge, these findings have not been reported in the international evidence. WHAT ARE THE IMPLICATIONS FOR PRACTICE?: Given these findings we suggest interventions such as Protected Engagement Time as well as reflective dialogues within interprofessional teams. This would help staff to resume their caring role in everyday life in psychiatric inpatient care and put their ideals into practice.
This paper constitutes a case-study of the `science show' model of public engagement employed by a company of science communicators focused on the popularization of science, technology, engineering and mathematics (STEM) subject disciplines with learner constituencies. It examines the potential of the science show to foster the interest and imagination of young learners in STEM; challenge popular pre/misconceptions of science and scientists; reveal the broadness, plurality and everyday relevance of science; and induce a more fluent and equitable science nexus between expert and non-expert or learner groups. Discussion focuses on conversations with members of a UK and university based science communication outfit who comment on the potential of the science show as a model of non-formal science education and science engagement and the necessary conditions for its success.
In this narrative review, the author synthesizes the literature on homelessness across various disciplines (e.g., public health, social work, sociology, and communication) to demonstrate how the experiences of homelessness can be created, maintained, and reinforced through communication, including interpersonal interactions and public discourse. By conceptualizing homelessness as a culturally constructed and socially situated phenomenon, the author examines (a) the complex conceptualization of homelessness, (b) everyday violence faced by people who are homeless, and (c) coping strategies of people who are homeless. In summary, homelessness is a complex social phenomenon, involving tensions between individuals, families, and social systems, all of which are situated in the larger sociocultural and sociopolitical contexts of a specific time and place.

Objective A growing body of research seeks to understand the relationship between mood and eating behaviors. Ecological Momentary Assessment (EMA) methods provide a method for assessing these processes in natural settings. We used EMA to examine the relationship between mood and eating behaviors in everyday life among women with subclinical disordered eating behaviors. Method Participants (N=127, age M=19.6, BMI M=25.5) completed 5 daily EMA reports on palmtop computers for 1 week. Assessments included measures of negative affect (NA) and eating-related behavior during eating (eating large amounts of food, loss of control over eating, restricting food intake) and non-eating episodes (skip eating to control weight/shape). Time-lagged multi-level models tested mood-eating behavior relationships. Results Higher NA did not precede any unhealthy eating and weight control behaviors. However, NA was higher when women reported eating large quantities of food, losing control over eating, and restricting food intake during their most recent eating episode, but not after skipping eating to control weight/shape. Discussion These findings elucidate processes in daily life that may influence the development and maintenance of unhealthy eating and weight control behaviors that, in turn, can inform interventions.

Using a series of online self-report measures, we examine media multitasking, a particularly pervasive form of multitasking, and its relations to three aspects of everyday attention: (1) failures of attention and cognitive errors (2) mind wandering, and (3) attentional control with an emphasis on attentional switching and distractibility. We observed a positive correlation between levels of media multitasking and self-reports of attentional failures, as well as with reports of both spontaneous and deliberate mind wandering. No correlation was observed between media multitasking and self-reported memory failures, lending credence to the hypothesis that media multitasking may be specifically related to problems of inattention, rather than cognitive errors in general. Furthermore, media multitasking was not related with self-reports of difficulties in attention switching or distractibility. We offer a plausible causal structural model assessing both direct and indirect effects among media multitasking, attentional failures, mind wandering, and cognitive errors, with the heuristic goal of constraining and motivating theories of the effects of media multitasking on inattention.

This article uses Probation Department files to reconstruct the lives of five ordinary residents of Harlem. It highlights what that black metropolis offered those outside the political and cultural elite, who have dominated historical scholarship, showing how ordinary blacks negotiated the challenges of life in northern neighborhoods, and drew on institutions and organizations, to establish and sustain new lives. We offer the kind of individualized perspective on everyday life that other scholars have provided for high culture, but which does not exist for other realms of existence in Harlem, even in early twentieth century sociological studies of black life. Where scholars seeking to distinguish the neighborhood from a slum have pointed to the prevailing pride and self-confidence of its residents, this article directs attention to more immediate, concrete supports that sustained and enriched life in Harlem. Relationships with spouses, children, siblings and cousins sustained individuals faced with the social reality of living in overcrowded, deteriorating, disease infested housing, subject to the racism of white police, politicians and employers; so too did friendships made in nightclubs, speakeasies, dances and movie theatres, and membership of churches, fraternal organizations, social clubs, and sports clubs and teams.

This study focuses on the everyday life of young persons with attention-deficit/hyperactivity disorder (ADHD) and autism spectrum disorder (ASD). There are follow-up studies describing ADHD, and ASD in adults, and residual impairments that affect life. Few qualitative studies have been conducted on the subject of their experiences of everyday life, and even fewer are from young persons' perspectives. This study's aim was to describe how young persons with ADHD and ASD function and how they manage their everyday life based on analyses of Internet-based chat logs. Twelve young persons (7 males and 5 females aged 15-26) diagnosed with ADHD and ASD were included consecutively and offered 8 weeks of Internet-based Support and Coaching (IBSC). Data were collected from 12 chat logs (445 pages of text) produced interactively by the participants and the coaches. Qualitative content analysis was applied. The text was coded and sorted into subthemes and further interpreted into themes. The findings revealed two themes: "fighting against an everyday life lived in vulnerability" with the following subthemes: "difficult things," "stress and rest," and "when feelings and thoughts are a concern"; and the theme "struggling to find a life of one's own" with the following subthemes: "decide and carry out," "making life choices," and "taking care of oneself." Dealing with the problematic situations that everyday encompasses requires personal strength and a desire to find adequate solutions, as well as to discover a role in society. This study, into the provision of support and coaching over the Internet, led to more in-depth knowledge about these young persons' everyday lives and revealed their ability to use IBSC to express the complexity of everyday life for young persons with ADHD and ASD. The implications of the findings are that using online coaching makes available new opportunities for healthcare professionals to acknowledge these young persons' problems.
Background: Aspects of daily life have been considered in a population of people with Down syndrome, followed repeatedly from infancy to 21-years old, and again at 30-, 35- and 40-years old. A control sample of non-disabled babies were seen at the same ages. Method: Parents (usually the mothers) and/or carers were interviewed about the people's…

Storytelling is a ubiquitous human activity that occurs across the lifespan as part of everyday life. Studies from three disparate literatures suggest that older adults (as compared to younger adults) are (a) less likely to recall story details, (b) more likely to go off-target when sharing stories, and, in contrast, (c) more likely to receive…

Although patients with major depressive disorder (MDD) report severe memory impairment in their everyday life, memory tests indicate only moderate deficits. In order to clarify these conflicting observations, the present study aimed at the investigation of MDD patients' memory performance in a real everyday life situation. The study included 20 MDD patients and 20 healthy control subjects. Nonverbal memory was assessed by means of the Rey Complex Figure Test whereas verbal memory was assessed by the recall of a 20-item wordlist with supermarket products. For the assessment of everyday life memory, subjects had to purchase as many products as possible of the 20-item wordlist in a real supermarket. Furthermore, subjects were asked for memory complaints. MDD patients' performance in the supermarket resembled memory test results and was not significantly impaired. MDD patients' self-reports, however, indicated severe memory problems that clearly fell below their performance in the supermarket. This study helped to identify everyday life-related factors that do not impair MDD patients' cognitive performance beyond their performance in standard laboratory testing situations. These factors may not be relevant for remediation programs that are specifically developed for depressed patients.

This article presents an empirically-grounded framework for mediating the everyday-life information worlds of youth aged 9-13. "Tweens" are a sandwiched population with behaviors, circumstances, and needs distinct from children and young adults. Little research has addressed their information-seeking, especially regarding nonschool contexts. Thus,…

HIV/AIDS education should empower students to create knowledge using everyday life experiences. Such knowledge should then be used to construe experience and resolve social problems such as risk behaviour that leads to infection. In South Africa, attempts to reduce the spread of HIV include incorporating HIV/AIDS education in the biology…

In the present study we examined the interrelation of everyday life handedness and hand preference in basketball, as an area of expertise that requires individuals being proficient with both their non-dominant and dominant hand. A secondary aim was to elucidate the link between basketball-specific practice, hand preference in basketball and everyday life handedness. Therefore, 176 expert basketball players self-reported their hand preference for activities of daily living and for basketball-specific behavior as well as details about their basketball-specific history via questionnaire. We found that compared to the general population the one-hand bias was significantly reduced for both everyday life and basketball-specific hand preference (i.e., a higher prevalence of mixed-handed individuals), and that both concepts were significantly related. Moreover, only preference scores for lay-up and dribbling skills were significantly related to measures of basketball-specific practice. Consequently, training-induced modulations of lateral preference seem to be very specific to only a few basketball-specific skills, and do not generalize to other skills within the domain of basketball nor do they extend into everyday life handedness. The results are discussed in terms of their relevance regarding theories of handedness and their practical implications for the sport of basketball.

Older men and women have different life contexts as a function of differential longevity and socio-structural opportunities over the life course. The question is whether gender-related differences also occur in psychological and everyday functioning in older adults. Examined were 258 men and 258 women between the ages of 70 and 103 years (M = 85 years), participants in the Berlin Aging Study. Significant gender differences were observed in 13 of 28 aspects of personality, social relationships, everyday activity patterns, and reported well-being. Cluster analysis identified 11 subgroups whose profiles of life conditions and health and psychological functioning could be categorized as more or less desirable (functional). The relative risk of a less desirable profile was 1.6 times higher for women than for men. For older adults, gender as a variable carries differences in physical frailty and life conditions that likely have consequences for psychological functioning.

A project called `Open life matrix' is not only a research activity but also real problem solving as an action research. This concept is realized by large-scale data collection, probabilistic causal structure model construction and information service providing using the model. One concrete outcome of this project is childhood injury prevention activity in new team consist of hospital, government, and many varieties of researchers. The main result from the project is a general methodology to apply probabilistic causal structure models as servicable knowledge for action research. In this paper, the summary of this project and future direction to emphasize action research driven by artificial intelligence technology are discussed.

Vygotsky (1987) stated that the restructured form of everyday concepts learned at home and in the community interact with scientific concepts introduced in formal school settings, leading to a higher level of scientific thinking for school-aged children. But, what does this mean for the scientific learning of infants and toddlers? What kinds of science learning are afforded at home during this early period of life? The study reported in this paper sought to investigate the scientific development of infants-toddlers (10 to 36 months) growing up in Bangladeshi families living in Australia and Singapore. Four families were studied over 2 years. Digital video observations were made of everyday family life and analysed using Vygotsky's theoretical framework of everyday concepts and scientific concepts (51 h of digital observations). While there are many possibilities for developing scientific concepts in infants-toddlers' everyday life, our study found four categories of what we have called small science: multiple possibilities for science; discrete science; embedded science and counter intuitive science. The findings of this study contribute to the almost non-existent literature into infants and toddlers' scientific development and advance new understandings of early childhood science education.

Little is known about narcissists’ everyday behavior. The goal of this study was to describe how narcissism is manifested in everyday life. Using the Electronically Activated Recorder (EAR), we obtained naturalistic behavior from participants’ everyday lives. The results suggest that the defining characteristics of narcissism that have been established from questionnaire and laboratory-based studies are borne out in narcissists’ day-to-day behaviors. Narcissists do indeed behave in more extraverted and less agreeable ways than non-narcissists, skip class more (among narcissists high in exploitativeness/entitlement only), and use more sexual language. Furthermore, we found that the link between narcissism and disagreeable behavior is strengthened when controlling for self-esteem, thus extending prior questionnaire-based findings (Paulhus, Robins, Trzesniewski, & Tracy, 2004) to observed, real-world behavior.

ClearVoice™ enables Advanced Bionics cochlear implant users to improve their speech understanding in difficult listening environments, without compromising performance in quiet situations. The aim of the study was to evaluate the benefits of ClearVoice in children. Children between six and fourteen years of age randomly tested two modalities of ClearVoice for one month each. The baseline program, HiRes 120™, and both ClearVoice programs were evaluated with a sentence test in quiet and noise. Parents and teachers completed a questionnaire related to everyday noisy situations. The switchover to ClearVoice was uneventful for both modalities. Adjustments to thresholds and comfort levels were required. Seven out of the nine children preferred a ClearVoice program. No impact of ClearVoice on performance in quiet was observed and both modalities of ClearVoice improved speech understanding in noise compared to the baseline program, significantly with ClearVoice high. Positive outcomes were obtained from the questionnaires and discussions with parents and children. This study showed that children benefited from using ClearVoice in their daily life. There was a clear trend towards improved speech understanding in noise with ClearVoice, without affecting performance in quiet; therefore ClearVoice can be used by children all day, without having to change programs.

Global warming is the most significant environmental issue of our time, yet public response in Western nations has been meager. Why have so few taken any action? Most studies of public response to climate change have focused on information deficit approaches. Many in the general public and environmental community have presumed that the public's failure to engage is a function of lack of concern about climate change. Instead, using interviews and ethnographic research on how knowledge of climate change is experienced in everyday life I describe "the social organization of climate denial" and discuss how it impacts classroom learning and the broader social understanding of climate change. Disturbing emotions of guilt, helplessness and fear of the future arose when people were confronted with the idea of climate change. People then normalized these disturbing emotions by changing the subject of conversations, shifting their attention elsewhere, telling jokes, and drawing on stock social discourses that deflected responsibility to others. The difficulty people have in making sense of climate change is in direct relation to the social world around them. This research suggests that educational strategies in the classroom and for the general public that consider and target the social, cultural and political aspects of the meaning of climate change will be most effective (in addition to factors that affect individual cognition).

The objective of this survey was to identify couples' joint perception of their satisfaction with life as a whole when one of the persons in the couple had acquired brain injury between one and five years earlier. The focus was on the influence that functioning and disability in everyday life have on the couple's joint life satisfaction after brain injury. The sample consisted of 55 couples, and the mean age of the brain-injured persons was 51 years. Both persons in the couple answered a mailed questionnaire encompassing questions concerning perceived impairments, activity limitations, participation restrictions, and life satisfaction. The results showed that in 16 of the 55 couples both partners were satisfied with life as a whole. The joint experience of life satisfaction was significantly related to the couple's functioning in everyday life, and specifically to perceived participation in leisure time and in their social life, and in their ability to wash clothes. Important implications from this study, showing that only one-third of the couples were satisfied, are that the partners should be included to a greater extent in the rehabilitation process and the couple's perspective of what they find difficult to deal with should serve as a guide during rehabilitation.

The"dysexecutive syndrome" is composed of a range of cognitive, emotional, and behavioral deficits that are difficult to evaluate using traditional neuropsychological tests. The Multiple Errands Test (MET) was originally developed to systematize the assessment of the more elusive manifestations of the dysexecutive syndrome. The aims of this study were to examining the reliability of the MET and to investigate the predictive ability of its indices to explain a range of "dysexecutive"-related symptoms in everyday life. Thirty patients with acquired brain injury participated in this study. The MET showed an adequate inter-rater reliability and ecological validity. The main performance indices from the MET were able to significantly predict severity of everyday life executive problems, with different indices predicting particular manifestations of different components of executive functions.

This article describes the subjective health views of young Finnish families with children. The data were collected in unstructured focused interviews with 19 families, most of whom were interviewed twice. Set within a phenomenological-hermeneutic framework, the study applies a qualitative method in order to uncover the meanings attached by the families to different facets of their everyday life. Health is an integral part of the everyday life of families with children, comprising various dimensions of experienced well-being and unwell-being, security and different life-habits. Social networks are crucial to family health: they can either strengthen or undermine experienced health. Professionals working with families in the health care system need to have at least a basic knowledge of the different dimensions of family health: this helps to identify and understand the individual ways in which families work to promote their health and well-being. This knowledge of family health is also important for research purposes. Health care professionals also need to know more about how families cope with their everyday problems and about how client families can be supported. More research is needed on the concepts of family health and on how those concepts are applied to practice in different health care sectors and in education.
Based on in-depth interviews, this study offers a comparison of how high-school students in China and Norway are actively constructing the Internet as an element of their everyday lives.

To understand prospective users' reactions to emergent technologies, it is crucial to examine the interactional contexts within which these reactions take place as people's reactions are shaped by issues that are not necessarily related to science or technology. These issues are often overshadowed or remain blind spots when descriptions or scenarios of proposed technologies are thematized as being the core objects of reference. We therefore recommend also studying prospective users' everyday-life practices in their own right, and in naturalistic settings. Insight into the social actions people accomplish in their everyday talk, such as establishing a particular identity, can help innovators translate prospective users' concerns into relevant technology characteristics. We propose discursive psychology as an analytic tool to do this and show its merit with a few illustrative examples.

Smelling monomolecular odors hardly ever occurs in everyday life, and the daily functioning of the sense of smell relies primarily on the processing of complex mixtures of volatiles that are present in the environment (e.g., emanating from food or conspecifics). Such processing allows for the instantaneous recognition and categorization of smells and also for the discrimination of odors among others to extract relevant information and to adapt efficiently in different contexts. The neurophysiological mechanisms underpinning this highly efficient analysis of complex mixtures of odorants is beginning to be unraveled and support the idea that olfaction, as vision and audition, relies on odor-objects encoding. This configural processing of odor mixtures, which is empirically subject to important applications in our societies (e.g., the art of perfumers, flavorists, and wine makers), has been scientifically studied only during the last decades. This processing depends on many individual factors, among which are the developmental stage, lifestyle, physiological and mood state, and cognitive skills; this processing also presents striking similarities between species. The present review gathers the recent findings, as observed in animals, healthy subjects, and/or individuals with affective disorders, supporting the perception of complex odor stimuli as odor objects. It also discusses peripheral to central processing, and cognitive and behavioral significance. Finally, this review highlights that the study of odor mixtures is an original window allowing for the investigation of daily olfaction and emphasizes the need for knowledge about the underlying biological processes, which appear to be crucial for our representation and adaptation to the chemical environment.

This study investigated relations between judgments of passage of time and judgments of long durations in everyday life with an experience sampling method. Several times per day, the participants received an alert via mobile phone. On each alert, at the same time as reporting their experience of the passage of time, the participants also estimated durations, between 3 and 33s in Experiment 1, and between 2 and 8min in Experiment 2. The participants' affective states and the difficulty and attentional demands of their current activity were also assessed. The results replicated others showing that affective states and the focus of attention on current activity are significant predictors of individual differences in passage-of-time judgments. In addition, the passage-of-time judgments were significantly related to the duration judgments but only for long durations of several minutes.

Objectives More adolescents report pain now than previously. In Norway, episodic pain problems have been reported by 60% of children and adolescents aged 8–18 years, with 21% reporting duration of pain of more than 3 months. Since adolescents spend much time at school, the attitude and behaviour of teachers play important roles regarding the experience of pain felt by adolescents in everyday life. Yet research on how teachers perceive the pain experienced by adolescents in a school setting is limited. We therefore seek to gain insight to teachers’ classroom experiences with (1) adolescent's self-reported pain symptoms; (2) adolescents management of their pain and (3) how to help adolescents manage their pain. Setting Teachers in 5 junior high schools in Norway representing municipalities in 3 rural areas and 2 cities. Research design A qualitative study with an explorative design comprising 5 focus group interviews. Each group consisted of 3–8 junior high school teachers. A semistructured interview guide was used to cover the issues. The transcribed text was analysed with qualitative content analysis. Participants 22 teachers participated (5 men, 17 women; age range 29–62 years) with teaching experience ranging from 3 to nearly 40 years. Results The main theme describing the experience of teachers with adolescents’ pain in everyday life is that pain and management of pain is a social, physical and psychological interwoven phenomenon. Through empirical analyses, 3 subcategories emerged: (1) everyday pain—expressing strenuous life; (2) managing pain—escaping struggle and (3) strategies of teachers—support and normalisation. Conclusions Teachers have a biopsychosocial understanding and approach to pain experienced by adolescents. This understanding influences the role of teachers as significant others in the lives of adolescents with regard to pain and management of their pain in a school setting. PMID:26338838

Research with people in highly politicized research settings illuminates the gap between the images that most African governments strive to represent and the sociopolitical realities of everyday life. This article discusses the opportunities and challenges of doing research in postgenocide Rwanda and is a useful resource for researchers contemplating their own projects under such conditions, whether in Rwanda or elsewhere. It discusses the importance of creating personal relationships and meeting people on their terms, as well as such topics as the identification of the research site, building rapport and trust with respondents, safeguarding anonymity and confidentiality, and working with local research assistants and partners.

Previous research has suggested that physically attractive people experience more positive life outcomes than do unattractive people. However, the importance of physical attractiveness in everyday life may vary depending on the extent to which different cultural worlds afford or require individual choice in the construction and maintenance of personal relationships. The authors hypothesized that attractiveness matters more for life outcomes in settings that promote voluntaristic-independent constructions of relationship as the product of personal choice than it does in settings that promote embedded-interdependent constructions of relationship as an environmental affordance. Study 1 examined self-reported outcomes of attractive and unattractive persons. Study 2 examined expectations about attractive and unattractive targets. Results provide support for the hypothesis along four dimensions: national context, relationship context, rural-urban context, and experimental manipulation of relationship constructions. These patterns suggest that the importance of physical attractiveness documented by psychological research is the product of particular constructions of reality.
The relations between everyday life and political participation are of interest for much contemporary social science. Yet studies of social movement protest still pay disproportionate attention to moments of mobilization, and to movements with clear organizational boundaries, tactics and goals. Exceptions have explored collective identity, 'free spaces' and prefigurative politics, but such processes are framed as important only in accounting for movements in abeyance, or in explaining movement persistence. This article focuses on the social practices taking place in and around social movement spaces, showing that political meanings, knowledge and alternative forms of social organization are continually being developed and cultivated. Social centres in Barcelona, Spain, autonomous political spaces hosting cultural and educational events, protest campaigns and alternative living arrangements, are used as empirical case studies. Daily practices of food provisioning, distributing space and dividing labour are politicized and politicizing as they unfold and develop over time and through diverse networks around social centres. Following Melucci, such latent processes set the conditions for social movements and mobilization to occur. However, they not only underpin mobilization, but are themselves politically expressive and prefigurative, with multiple layers of latency and visibility identifiable in performances of practices. The variety of political forms - adversarial, expressive, theoretical, and routinized everyday practices, allow diverse identities, materialities and meanings to overlap in movement spaces, and help explain networks of mutual support between loosely knit networks of activists and non-activists. An approach which focuses on practices and networks rather than mobilization and collective actors, it is argued, helps show how everyday life and political protest are mutually constitutive.
Social change and large-scale transformations are as important to everyday life sociology as to macro sociology approaches. South Africa has been a 'hotspot' of change with a number of such transitions occurring in a condensed time-period, in particular regarding 'race' matters. A large South African family collection, concerning the Forbes family, is used to explore how the processes of change regarding the racial order can be analysed within an everyday sociology framework, focusing on the period 1850 to 1930. A range of documents throwing light on 'the space of the day', 'the world and the word' and other aspects of everyday experience are discussed.

The growing role of Internet in all aspects of everyday life has led to speculations over the impacts beyond the traditional questions of access or sociability. This in mind, the main focus in this article was to examine how Finns, for majority of whom Internet use has become commonplace activity, perceive the impacts of Internet use since first adopting the technology. In this study, we examine how Internet user history and perceived computer skills, along with different sociodemographic factors, appear to reflect on the perceived impacts of Internet adoption in terms of memory and ability to concentrate. According to the results, almost one in five of the respondents reported changes concerning their memory or ability to concentrate, with skilled computer users and nonworkers, in particular, perceiving the change. Factors such as age-related differences and exposure to potential information overload at work were identified to explain the perceived change. Our data were collected in a survey-gathering information on the everyday life and well-being of Finns. The sample consisted of 2000 Finnish speakers aged 15 to 64 years. The response rate was 46 percent (N=908).

Being diagnosed with Alzheimer's disease marks a status passage formally legitimating the incorporation of forgetfulness into daily life. Based on interviews with diagnosed individuals in California, USA, we examine the mechanisms through which an Alzheimer's label is employed to justify forgetfulness, to manage social interactions, and to garner support when deemed necessary, while simultaneously combating the associated demented "master status." For diagnosed individuals, the transition from experience to symptom requires a redefinition of everyday forgetfulness into a medical problem. That is, respondents did not routinely perceive their experiences as pathological but rather were socialised into viewing age-related forgetfulness as symbolic of disease. Support groups sponsored by the Alzheimer's Association and memory clinics have a profound impact not only on the formation of group identity, but also on socialising forgetful individuals into diseased identities. The social disenfranchisement accompanying a diagnosis of dementia transforms forgetful older adults into "Alzheimer's patients," who must manage not only the manifestations of their disease, but also negotiate their interactions and identities. Their adaptation to the "symptoms" of forgetfulness and resultant social relations forms new interactional strategies whereby the diagnosis becomes a resource utilised to get through everyday life. Rather than being passive recipients of a diagnosis, respondents employ the label both as a resource, and as a phenomenon that needs to be incorporated into their self identity.

The use of digital portable music devices such as MP3 players has rapidly increased during the last decade, and the sheer availability of music offered by such players raises questions about their impact on listeners' mental and physical health and well-being. This article explores MP3 player use as an everyday tactic for affect regulation, here understood as an individual's efforts to maintain or change the intensity or duration of a given affect. The ability to understand and regulate affects has significant health implications, and among the tactics relevant to such regulation, engagement with music has proven to be particularly successful. The material presented in this article is based on a qualitative interview study focused on MP3 player use as a medium for musical self-care. Because MP3 users can listen to whatever they want, whenever they want, and target their music in the interests of managing and regulating moods and emotions, the MP3 player represents a valuable and convenient technology of affect regulation.

I suggest that Juma's experiences and the life trajectory of himself and of significant individuals around him (particularly his mother) were structured by everyday violence. I describe everyday violence in terms of a conjuncture between macrostructural forces in East Africa (including a history of failed development schemes and the contemporary political economy of neoliberalism) and the lived experience of individuals as they negotiate local, contextual factors (including land-tenure practices, the power dynamics between immediate and extended kin, life on the streets, and constructions of gender and sexuality). I suggest that AIDS and its many impacts on Juma's life course can only be understood in a broader context of everyday violence. From this basis, I draw several general conclusions regarding AIDS prevention and intervention strategies.

Aim To explore and describe the essential meaning of lived experiences of the phenomenon: Everyday life during curative radiotherapy in patients with non-small-cell lung cancer (NSCLC). Background Radiotherapy treatment in patients with NSCLC is associated with severe side effects such as fatigue, anxiety, and reduced quality of life. However, little is known about the patients’ experience of everyday life during the care trajectory. Design This study takes a reflective lifeworld approach using an empirical application of phenomenological philosophy described by Dahlberg and colleagues. Method A sample of three patients treated with curative radiotherapy for NSCLC was interviewed 3 weeks after the end of radiotherapy treatment about their experiences of everyday life during their treatment. Data were collected in 2014 and interviews and analysis were conducted within the descriptive phenomenological framework. Findings The essential meaning structure of the phenomenon studied was described as “Hope for recovery serving as a compass in a changed everyday life,” which was a guide for the patients through the radiotherapy treatment to support their efforts in coping with side effects. The constituents of the structure were: Radiotherapy as a life priority, A struggle for acceptance of an altered everyday life, Interpersonal relationships for better or worse, and Meeting the health care system. Conclusion The meaning of hope was essential during radiotherapy treatment and our results suggest that interpersonal relationships can be a prerequisite to the experience of hope. “Hope for recovery serving as a compass in a changed everyday life,” furthermore identifies the essentials in the patients’ assertive approach to believing in recovery and thereby enabling hope in a serious situation.

Numerous studies investigated executive functioning (EF) problems in people with autism spectrum disorders (ASD) using laboratory EF tasks. As laboratory task performances often differ from real life observations, the current study focused on EF in everyday life of 118 children and adolescents with ASD (6-18 years). We investigated age-related and…

One of the founding assumptions underlying the health professions is the belief that there is a strong relationship between engagement in occupations, health, and wellbeing. The ability to perform everyday occupations (occupational performance) has a positive effect on health and wellbeing. However, there is also conflicting evidence indicating that participation in multiple roles or in certain occupations may lead to poorer health. Therefore, there is a need to better understand this relationship. The purpose of the present study was to examine three possible theoretical models to explain mothers' health and life satisfaction from the perspective of their occupational performance, their role load, and their social support. 150 married mothers, ages of 25-45, who had at least one child between the ages of one to ten years, participated in the study. Data were collected by using seven self-report questionnaires. The models were analyzed using Structural Equation Modeling. The results show that social support has a direct effect on mothers' physical health and life satisfaction and an indirect effect, mediated through the occupational performance variables, on mothers' mental health and life satisfaction. Role overload does not affect mothers' health and life satisfaction. These results suggest that mothers could benefit from health programs that help them manage their occupational routines. Such programs should focus on improving the mother's occupational performance and adapting her social environment to fit her occupational needs.

The aim of the present study is to describe and understand the meaning of living with alcohol dependency (AD) as a man. Studies point out a high prevalence of AD in men and the reasons for, and consequences of, that are complex. However, today there is a lack of knowledge about men's lived experiences of having AD. In-depth interviews were conducted with 15 alcohol dependent men and analyzed using a phenomenological-hermeneutic approach. In the comprehensive understanding, findings from the naïve understanding and the structural analysis were interpreted with help from both gender and caring theoretical perspectives. "A Fallible Man" and "A Man with Powerfulness" were disclosed as two main gender formations influencing senses of well-being. A Fallible Man involved varying experiences of restrictions, being in control, and meaninglessness. Being in control promoted a sense of well-being. A Man with Powerfulness involved energetic activity, and the development and maintaining of interests as well as risk-taking. Being powerful diminished feelings of meaninglessness, cravings, and social alienation. The results show, among other things, that the men live an incompatible life and, because of that, need support and guidance to find a more meaningful life. This can be accomplished if caregivers allow men to be in focus and involved in planning their own care. To avoid limiting the men while they are in treatment, the health care professionals also need to focus on the men's everyday life. This focus involves acknowledging the men's individual experiences of what enriches and limits their everyday lives.

Laboratory research shows that when people believe that willpower is an abundant (rather than highly limited) resource they exhibit better self-control after demanding tasks. However, some have questioned whether this "nonlimited" theory leads to squandering of resources and worse outcomes in everyday life when demands on self-regulation are high. To examine this, we conducted a longitudinal study, assessing students' theories about willpower and tracking their self-regulation and academic performance. As hypothesized, a nonlimited theory predicted better self-regulation (better time management and less procrastination, unhealthy eating, and impulsive spending) for students who faced high self-regulatory demands. Moreover, among students taking a heavy course load, those with a nonlimited theory earned higher grades, which was mediated by less procrastination. These findings contradict the idea that a limited theory helps people allocate their resources more effectively; instead, it is people with the nonlimited theory who self-regulate well in the face of high demands.

Approximately 37 thousand Malians currently reside in France as part of the West African diaspora. Primarily Muslim, both women and men confront challenges to their understandings of Islamic prohibitions and expectations, especially those addressing conjugal relations and reproduction. Biomedical policies generate marital conflicts and pose health dilemmas for women who face family and community pressures to reproduce but biomedical encouragement to limit childbearing. For many women, contraception represents a reprieve from repeated pregnancies and fatigue in spite of resistance from those who contest women's reproductive decisions as antithetical to Islam. French social workers play a particularly controversial role by introducing women to a discourse of women's rights that questions the authority of husbands and of religious doctrine. Women and men frame decisions and debate in diverse interpretations of Islam as they seek to manage the contradictions of everyday life and assert individual agency in the context of immigration and health politics.

Background This paper is a commentary to a debate article entitled: “Are we overpathologizing everyday life? A tenable blueprint for behavioral addiction research”, by Billieux et al. (2015). Methods and aim This brief response focused on the necessity to better characterize psychological and related neurocognitive determinants of persistent deleterious actions associated or not with substance utilization. Results A majority of addicted people could be driven by psychological functional reasons to keep using drugs, gambling or buying despite the growing number of related negative consequences. In addition, a non-negligible proportion of them would need assistance to restore profound disturbances in basic learning processes involved in compulsive actions. Conclusions The distinction between psychological functionality and compulsive aspects of addictive behaviors should represent a big step towards more efficient treatments. PMID:26551899

This article presents results from four studies of the significance of type and number of initial treatment motives for acquisition and transfer to everyday life of progressive relaxation (PR) and autogenic training (AT). On the basis of theories of treatment motivation and compliance, we hypothesize that motives for participation are determinants of learning and transfer. Results are reported from (1) two studies with 113 participants in introductory courses on AT and 94 participants in introductory courses on PR and (2) two replication studies with 94 (AT) and 101 participants (PR). Participants indicated their motives for participation. Short-term indicators of treatment success include number of dropouts and subjective evaluations of relaxation exercises; long-term outcomes include transfer of relaxation exercises to everyday life and evaluations of exercise evaluations at follow-up 3 to 6 months after the end of course. Results suggest that for both AT and PR, dropout and subjective relaxation exercise evaluations can be predicted from participation motives. Long-term outcomes can be predicted only for AT. However, for both PR and AT it is shown that for up to four motives, the number of initial course motives is correlated with short-term and long-term predictors of course outcome. We conclude that motivation for participation is highly relevant to client-course matching and adaptive indication of relaxation therapies. Results lead to a threshold hypothesis about the relationship between the number of participation motives and short-term as well as long-term learning and transfer outcome.

This article provides a critique of the concept of reflexivity in social theory today and argues against the tendency to define agency exclusively in terms of reflexivity. Margaret Archer, in particular, is highlighted as a key proponent of this thesis. Archer argues that late modernity is characterized by reflexivity but, in our view, this position neglects the impact of more enduring aspects of agency, such as the routinization of social life and the role of the taken-for-granted. These concepts were pivotal to Bourdieu and Giddens' theorization of everyday life and action and to Foucault's understanding of technologies of the self. We offer Bourdieu's habitus as a more nuanced approach to theorizing agency, and provide an alternative account of reflexivity. Whilst accepting that reflexivity is a core aspect of agency, we argue that it operates to a backdrop of the routinization of social life and operates from within and not outside of habitus. We highlight the role of the breach in reflexivity, suggesting that it opens up a critical window for agents to initiate change. The article suggests caution in over-ascribing reflexivity to agency, instead arguing that achieving reflexivity and change is a difficult and fraught process, which has emotional and moral consequences. The effect of this is that people often prefer the status quo, rather than to risk change and uncertainty.

Background The high prevalence of diabetes among South Asian populations in European countries partially derives from unhealthy changes in dietary patterns. Limited studies address perspectives of South Asian populations with respect to utility of diabetes education in everyday life. This study explores perspectives on dietary diabetes education and healthy food choices of people living in Denmark who have a Pakistani background and type 2 diabetes. Methods In-depth interviews were conducted between October 2012 and December 2013 with 12 participants with type 2 diabetes who had received dietary diabetes education. Data analysis was systematic and was based on grounded theory principles. Results Participants described the process of integrating and utilizing dietary education in everyday life as challenging. Perceived barriers of the integration and utilization included a lack of a connection between the content of the education and life conditions, a lack of support from their social networks for dietary change, difficulty integrating the education into everyday life, and failure to include the participants’ taste preferences in the educational setting. Conclusion Dietary education that is sensitive to the attitudes, wishes, and preferences of the participants and that aims at establishing a connection to the everyday life of the participants might facilitate successful changes in dietary practices among people with a Pakistani background and type 2 diabetes. The findings suggest that more focus should be placed on collaborative processes in the dietary educational setting in order to achieve appropriate education and to improve communication between this population and health care professionals.

Heat waves and the consequent heat stress of urban populations have a growing relevance in urban risk management and strategies of urban adaptation to climate change. In this context, social science studies on subjective experiencing of heat as stress by urban citizens are a new emerging field. To contribute to the understanding of self-reported subjective heat stress and its major determinants in a daily life perspective, we conducted a questionnaire survey with 323 respondents in Karlsruhe, Germany, after heat waves in July and August 2013. Statistical data analysis showed that subjective heat stress is an issue permeating everyday activities. Subjective heat stress at home was lower than at work and in general. Subjective heat stress in general, at home, and at work was determined by the health impairments experienced during the heat and the feeling of being helplessly exposed to the heat. For subjective heat stress at home, characteristics of the residential building and the built environment additionally played a role. Although the rate of implemented coping measures was rather high, coping measures showed no uniform effect for the subjective heat stress. We conclude that in terms of urban adaptation strategies, further research is needed to understand how various processes of daily social (work) life enable or limit individual coping and that communication strategies are important for building capacities to better cope with future heat waves.
Social change and large-scale transformations are as important to everyday life sociology as to macro sociology approaches. South Africa has been a ‘hotspot’ of change with a number of such transitions occurring in a condensed time-period, in particular regarding ‘race’ matters. A large South African family collection, concerning the Forbes family, is used to explore how the processes of change regarding the racial order can be analysed within an everyday sociology framework, focusing on the period 1850 to 1930. A range of documents throwing light on ‘the space of the day’, ‘the world and the word’ and other aspects of everyday experience are discussed. PMID:26456982

In the present paper, we suggest an algorithm for a sensor agent robot with a laser range finder to recognize the flows of residents in the living spaces in order to achieve flow recognition in the living spaces, recognition of the number of people in spaces, and the classification of the flows. House reform is or will be demanded to prolong the lifetime of the home. Adaption for the individuals is needed for our aging society which is growing at a rapid pace. Home autonomous mobile robots will become popular in the future for aged people to assist them in various situations. Therefore we have to collect various type of information of human and living spaces. However, a penetration in personal privacy must be avoided. It is essential to recognize flows in everyday life in order to assist house reforms and aging societies in terms of adaption for the individuals. With background subtraction, extra noise removal, and the clustering based k-means method, we got an average accuracy of more than 90% from the behavior from 1 to 3 persons, and also confirmed the reliability of our system no matter the position of the sensor. Our system can take advantages from autonomous mobile robots and protect the personal privacy. It hints at a generalization of flow recognition methods in the living spaces.

Recurrent involuntary memories are autobiographical memories that come to mind with no preceding retrieval attempt and that are subjectively experienced as being repetitive. Clinically, they are classified as a symptom of Posttraumatic Stress Disorder (PTSD). The present work is the first to systematically examine recurrent involuntary memories outside clinical settings. Study 1 examines recurrent involuntary memories among survivors of the tsunami catastrophe in Southeast Asia in 2004. Study 2 examines recurrent involuntary memories in a large general population. Study 3 examines whether the contents of recurrent involuntary memories recorded in a diary study are duplicates of, or differ from, one another. We show that recurrent involuntary memories are not limited to clinical populations or to emotionally negative experiences, that they typically do not come to mind in a fixed and unchangeable form, and that they show the same pattern regarding accessibility as autobiographical memories in general. We argue that recurrent involuntary memories after traumas and in everyday life can be explained in terms of general and well-established mechanisms of autobiographical memory. PMID:18426073

The support of social networks is a fundamental aspect for the social inclusion of people with mental health problems. This study seeks to identify and analyze the difficulties and possibilities of users of a Psychosocial Care Center (CAPS) in building their extended social network. The qualitative approach was used as the research methodology and Ágnes Heller's concept about everyday life was used as a philosophical benchmark. The subjects in this investigation were frequenters of Psychosocial Care Centers with people from their social network. Semi-structured interviews were conducted for the data gathering and discourse analysis was used for examining the data. It was seen that although this population is living in the community it is frequently segregated and isolated from living together with other people, thereby leading to social exclusion. Nevertheless, CAPS are a space of belonging and welcoming that undeniably produce favorable changes in the users' lives. People with mental health problems have also been able to relate to others in CAPS. By using the available opportunities, they make new friends and maintain friendships they already had. Living with others in the community is highly conducive to the formation of relationships.

This study illuminates adult relatives' experiences of everyday life close to a person with mental ill-health. The study was based on nine diaries and four narrative interviews with relatives of people with mental ill-health. Data were subjected to qualitative content analysis. The participants experienced everyday life as a constant fight, for better and for worse, with psychiatric care. They were fighting for the mentally ill person's right to care; sometimes they felt resigned, but yet they had a confidence in the care. Their mission in life was to sacrifice themselves, meaning that they felt indispensable and became lonely and socially isolated. They considered their mission to last until death set them apart because they were keeping a family secret, and had great worries about the future. We conclude that relatives experience a two-folded stigma in living close to a person with mental ill-health and in becoming lonely and socially isolated.

The impact of life on the atmosphere is examined through a discussion of the budgets of important atmospheric constituents and the processes that control their concentrations. Life profoundly influences oxygen and a number of minor atmospheric constituents, but many important gases, including those with the greatest effect on global climate, appear to be little altered by biological processes, at least in the steady state.

The study of spontaneous and everyday cognitions is an area of rapidly growing interest. One of the most ubiquitous forms of spontaneous cognition is involuntary musical imagery (INMI), the involuntarily retrieved and repetitive mental replay of music. The present study introduced a novel method for capturing temporal features of INMI within a naturalistic setting. This method allowed for the investigation of two questions of interest to INMI researchers in a more objective way than previously possible, concerning (1) the precision of memory representations within INMI and (2) the interactions between INMI and concurrent affective state. Over the course of 4 days, INMI tempo was measured by asking participants to tap to the beat of their INMI with a wrist-worn accelerometer. Participants documented additional details regarding their INMI in a diary. Overall, the tempo of music within INMI was recalled from long-term memory in a highly veridical form, although with a regression to the mean for recalled tempo that parallels previous findings on voluntary musical imagery. A significant positive relationship was found between INMI tempo and subjective arousal, suggesting that INMI interacts with concurrent mood in a similar manner to perceived music. The results suggest several parallels between INMI and voluntary imagery, music perceptual processes, and other types of involuntary memories.

Parents of children diagnosed with a brain tumor often report distress, even after successfully completed cancer treatment. The aim of this study was to examine predictors of burnout (ie stress-induced exhaustion) in parents of children who have had a brain tumor. Twenty-four mothers and 20 fathers completed self-report questionnaires on 2 occasions at an interval of 7 months. Controlling for generic stress, parents' perception of the influence of the disease on everyday life-predicted burnout symptoms. Moreover, parents' appraisal of a disease-related influence on everyday life showed stability, implying that parental stress may be chronic. The findings encourage furthermore investigation of chronic stress among parents of children diagnosed with cancer.

The ability to predict and anticipate the mechanical demands of the environment promotes smooth and skillful motor actions. Thus, the finger forces produced to grasp and lift an object are scaled to the physical properties such as weight. While grip force scaling is well established for neutral objects, only few studies analyzed objects known from daily routine and none studied grip forces. In the present study, eleven healthy subjects each lifted twelve objects of everyday life that encompassed a wide range of weights. The finger pads were covered with force sensors that enabled the measurement of grip force. A scale registered load forces. In a control experiment, the objects were wrapped into paper to prevent recognition by the subjects. Data from the first lift of each object confirmed that object weight was anticipated by adequately scaled forces. The maximum grip force rate during the force increase phase emerged as the most reliable measure to verify that weight was actually predicted and to characterize the precision of this prediction, while other force measures were scaled to object weight also when object identity was not known. Variability and linearity of the grip force-weight relationship improved for time points reached after liftoff, suggesting that sensory information refined the force adjustment. The same mechanism seemed to be involved with unrecognizable objects, though a lower precision was reached. Repeated lifting of the same object within a second and third presentation block did not improve the precision of the grip force scaling. Either practice was too variable or the motor system does not prioritize the optimization of the internal representation when objects are highly familiar.

Natural, everyday sensorimotor behaviors, such as rising from sitting, typically have an intrinsic organization of several levels of analysis. Taking this intrinsic organization as key to understanding neural dynamics is neither a top-down nor a bottom-up approach, but rather a meshing of multiple centers and levels of analysis. Motor control requires body dynamics that are consistent with physical dynamics, besides the more microscopic levels of neural dynamics. The dynamics of separate movements have been investigated as if the ends can be capped off, separated from the rest of the individual's life. Is this dynamically correct? Even chaotic behavior is deterministic. However, the mathematics of nonlinear oscillations is not all of dynamics. This paper relates Bloch's dynamical theorem to the modular, conditional approach to sensorimotor and other neural functioning. Bloch's dynamical theorem lays a foundation for the piecewise study of structurally accurate dynamics in theoretical neurobiology. Piecewise studies can be used as a modeling option complementary to the methods of nonlinear oscillator dynamics. By applying Bloch's theorem, dynamics of movements analyzed piecewise can be extended into a smooth flow on any manifold, either as a whole or conditionally. Conditional dynamics makes dynamical modeling options explicit, often depending on what variables the organism can control, and allows one to take different modeling options at different junctures in analyzing the same phenomenon. For example, this approach allows the study of complex motor control problems to be reduced to modular constructions using singularities and flow lines. Dynamical contingencies are expressed using the mathematics of ordered structures. This paper presents Bloch's dynamical theorem and its relevance to model construction in theoretical neurobiology. Specific examples, integrated into physiological and behavioral context, are cited from the literature.
The speed of light, or more generally, the speed of electromagnetic waves, seems to be incredibly high. 300 000 km s[superscript -1] is far greater than the typical speed of a car, a plane or even a rocket, which is just several kilometres per second. It is thus natural that we treat the speed of light as infinite in everyday life. It appears,…

Aim The aim of this study was to describe the experiences and meaning of using mobile phones in everyday life after stroke, among persons with stroke and their family members. Methods Qualitative semi-structured interviews were conducted among 11 persons with stroke and 9 family members 2 months to 2 years after the stroke. The interviews were analysed by using constant comparative grounded theory (GT) approach. Results Seven categories were identified from the analysis of the participants' experiences. The mobile phone: (1) as an enabler of communication and connections with other people, (2) a source of inspiration for agency, (3) structuring routine and activities in daily life, (4) as a facilitator of social and economic wellbeing of an individual or family, (5) promoter of belonging and participation in social relationships, (6) facilitator of reintegration to community living and (7) enabler of family members to feel secure. From these categories, a core category emerged: The mobile phone as a "life line" and an extension of the body enabling connection, belonging and agency to act in a complex everyday life situation. Conclusion The study gives support for the possibility of using mobile phones to facilitate change and community integration in the rehabilitation process after stroke. Implications for Rehabilitation Stroke leads to decreased functioning in everyday life due to impairments, activity limitations and participation restrictions as well caregiver burden. Mobile phones seem to be an accessible and affordable technology used in daily life of persons with stroke and family members and connects them to the needed services and social relationships. The mobile phone technology reduces resource and infrastructural challenges and increases accessibility to rehabilitation interventions. The mobile phone was an important instrument that facilitated the quality of life of persons with stroke and their family members and could increase their participation in

This study investigated how the neuronal underpinnings of both adaptive and stable cognitive control processes are affected by traumatic brain injury (TBI). Functional magnetic resonance imaging (fMRI) was undertaken in 62 survivors of moderate-to-severe TBI (>1 year after injury) and 68 healthy controls during performance of a continuous performance test adapted for use in a mixed block- and event-related design. Survivors of TBI demonstrated increased reliance on adaptive task control processes within an a priori core region for cognitive control in the medial frontal cortex. TBI survivors also had increased activations related to time-on-task effects during stable task-set maintenance in right inferior parietal and prefrontal cortices. Increased brain activations in TBI survivors had a dose-dependent linear positive relationship to injury severity and were negatively correlated with self-reported cognitive control problems in everyday-life situations. Results were adjusted for age, education, and fMRI task performance. In conclusion, evidence was provided that the neural underpinnings of adaptive and stable control processes are differently affected by TBI. Moreover, it was demonstrated that increased brain activations typically observed in survivors of TBI might represent injury-specific compensatory adaptations also utilized in everyday-life situations.

The purpose of this mixed method case study was to examine the effects of methods of instruction on students' perception of relevance in higher education non-biology majors' courses. Nearly ninety percent of all students in a liberal arts college are required to take a general biology course. It is proposed that for many of those students, this is the last science course they will take for life. General biology courses are suspected of discouraging student interest in biology with large enrollment, didactic instruction, covering a huge amount of content in one semester, and are charged with promoting student disengagement with biology by the end of the course. Previous research has been aimed at increasing student motivation and interest in biology as measured by surveys and test results. Various methods of instruction have been tested and show evidence of improved learning gains. This study focused on students' perception of relevance of biology content to everyday life and the methods of instruction that increase it. A quantitative survey was administered to assess perception of relevance pre and post instruction over three topics typically taught in a general biology course. A second quantitative survey of student experiences during instruction was administered to identify methods of instruction used in the course lecture and lab. While perception of relevance dropped in the study, qualitative focus groups provided insight into the surprising results by identifying topics that are more relevant than the ones chosen for the study, conveying the affects of the instructor's personal and instructional skills on student engagement, explanation of how active engagement during instruction promotes understanding of relevance, the roll of laboratory in promoting students' understanding of relevance as well as identifying external factors that affect student engagement. The study also investigated the extent to which gender affected changes in students' perception of

This qualitative study explored the impact of Clostridium difficile infections on nurses' everyday work in the hospital. Twelve nurses (six in France and six in the United States) were interviewed in depth using a semi-structured interview guide. Thematic analysis of the interviews was performed. Managing diarrhoea and taking precautionary measures for infection control were the two most inconvenient aspects nurses reported with C. difficile patient management. Precautions included contact isolation, hand hygiene and reorganization/coordination of nursing care and ward. Precautions were time consuming and significantly increased nurses' workload when combined with caring for patients with uncontrollable, frequent bouts of diarrhoea. Management of C. difficile infection is extremely burdensome for nurses in their everyday work and disruptive to hospital organizations as a whole. Prevention of C. difficile infections, together with coordinated team work and communication, would therefore contribute to decreasing nurses' workload and the burden to health-care facilities associated with caring for these patients.

Research shows that people with late-onset dementia and their relatives can benefit from using assistive technology (AT). Few researchers have investigated the use and utility of AT in everyday life for younger people with dementia (YPD) and their family carers. The aim of this study is to explore what characterised the implementation process when the AT was experienced as beneficial to the YPD and the family carer in their daily life. The qualitative longitudinal study followed 12 younger people (i.e. those under 65 years of age), who had recently been diagnosed with dementia and 14 of their family carers. In-depth interviews and observations during the process were conducted at the beginning, and were repeated every 3rd month for up to 12 months. The data were analysed, and the participants' experiences further discussed on the basis of embodied, social- and everyday life-situated approaches, in order to provide a deeper understanding of the interactive processes involved in the trajectory. Five elements in the process were identified as important for the experience of usefulness and successful incorporation of AT. The AT had to: (1) be valuable by addressing practical, emotional, and relational challenges; (2) fit well into, or be a better solution for, habitual practice and established strategies; (3) generate positive emotions, and become a reliable and trustworthy tool; (4) be user-friendly, adaptable, and manageable; and (5) interest and engage the family carer. The study demonstrated the importance of understanding the use and utility of AT on the basis of embodied and social participation in daily life. The family carers played a significant role in whether or not, and in which ways, AT was absorbed into the everyday life practice of YPD.

We propose from the Marxist perspective of the construction of knowledge, a theoretical and methodological framework for understanding social values by capturing everyday representations. We assume that scientific research brings together different dimensions: epistemological, theoretical and methodological that consistently to the other instances, proposes a set of operating procedures and techniques for capturing and analyzing the reality under study in order to expose the investigated object. The study of values reveals the essentiality of the formation of judgments and choices, there are values that reflect the dominant ideology, spanning all social classes, but there are values that reflect class interests, these are not universal, they are formed in relationships and social activities. Basing on the Marxist theory of consciousness, representations are discursive formulations of everyday life - opinion or conviction - issued by subjects about their reality, being a coherent way of understanding and exposure social values: focus groups show is suitable for grasping opinions while interviews show potential to expose convictions.

Vygotsky (1987) stated that the restructured form of everyday concepts learned at home and in the community interact with scientific concepts introduced in formal school settings, leading to a higher level of scientific thinking for school-aged children. But, what does this mean for the scientific learning of infants and toddlers? What kinds of…

Examined the everyday lives of adolescents with low, middle, or high levels of attention-deficit hyperactivity disorder (ADHD) as assessed by either parent or teen. Found that adolescents with high ADHD levels recorded more negative moods, lower alertness, more entertaining activities relative to achievement-oriented pursuits, more time with…
There have been two views as to mood congruent recall: The one interprets it as an automatic process, while the other explains that it appears only when self-referent information processing is running. In this study, one experiment was conducted in order to examine these two opposing views. By false feedback of task performance, positive or negative mood had been induced in each subject, who was given two "cue" words, and asked to retrieve everyday events. The result was that mood congruent recall occurred when the word "self" was presented as a cue; but no effect of mood with neutral cues. This result supports the hypothesis that mood congruent recall is found only when self-referent information is processed. However, such effect was not evident in positive mood condition. In positive mood condition, there remains a possibility that mood congruent recall may be an automatic process. The effects of mood on memory were discussed from various viewpoints.

Ten structurally diverse chemicals (vitamins C, B9, B6, B3, sucrose, caffeine, gingerol, xanthan gum, paracetamol, ibuprofen) deemed intrinsic to modern life but not considered as endocrine active, were tested in vitro using the human estrogen receptor transcriptional activation (hERTa) and the H295R steroidogenesis assays. All were inactive in the hERTa assay but paracetamol, gingerol, caffeine and vitamin C affected steroidogenesis in vitro from 250, 25, 500 and 750 μM respectively. One molecule, caffeine, was further tested in rat pubertal assays at the tumorigenic dose-level and at dose-levels relevant for human consumption. In females pubertal parameters (vaginal opening, estrus cycle), ovarian weight and Fsh and prolactin transcript levels were affected. In males, plasma progesterone levels and prostate and seminal vesicle weights were affected. Although the current regulatory focus is synthetic chemicals that can cause adverse effects on the hypothalamus-pituitary-gonadal axis, our data infer that the range of natural chemicals with the potential to affect this axis may be extensive and is probably overlooked. Thus, to avoid regulation of an overwhelming number of chemicals, a weight of evidence approach, combining hazard identification and characterization with exposure considerations, is needed to identify those chemicals of real regulatory concern.
Using interview data from white, middle-class men and women, ages 35-55, the research explores the phenomenological, embodied aspects of health. Health is found to be grounded in a sense of self and a sense of body, both of which are tied to conceptions of past and future actions. Gender is a leitmotif. The body, as the focal point of self-construction as well as health construction, implicates gender in the everyday experience of health. The interplay between health, self, body, and gender at the individual level is linked to the creation of a sense of healthiness in the body politic of society. If social psychological theories of health are to reflect adequately the everyday experience of health, they must begin to take into account the body as individually and socially problematic.

East Asians and Asian Americans report lower levels of subjective well-being than Europeans and European Americans. Three studies found support for the hypothesis that such differences may be due to the psychological meanings Eastern and Western cultures attach to positive and negative affect. Study 1 demonstrated that the desire to repeat a recent vacation was significantly predicted by recalled positive affect-but not recalled negative affect-for European Americans, whereas Asian Americans considered both positive and negative affect. Study 2 replicated this effect in judging satisfaction with a personal friendship. Study 3 linked changes in European Americans' life satisfaction to everyday positive events caused by the self (vs. others) and changes in Japanese life satisfaction to everyday negative events caused by others (vs. the self). Positive affect appears particularly meaningful for European Americans and negative affect for Asian Americans and Japanese when judging a satisfying vacation, friendship, or life.

Objectives The present study of a representative sample of older adults quantified everyday physical activity (EPA) by having participants wear actigraphs. Our objectives were to examine whether poor health may partly explain why older adults become less physically active with advancing age and whether gender might moderate the extent to which health status predicts EPA. Methods We performed multiple regression analyses on a sample of older, community-dwelling adults (aged 80–98 years, N = 198; women = 63.1%). Results The results imply that age-related declines in EPA may be partially accounted for by health (in men) and by living arrangements (in women). Discussion We consider reasons why poorer health might erode EPA for men (but not women) and why living alone might erode EPA for women (but not men). PMID:18689770

Depression is a prevalent and debilitating illness facing many adolescents, especially adolescent girls, whose risk for this disorder is approximately twice that of boys. Many studies have identified mechanisms that place girls at higher risk for depression during adolescence. Few, however, have examined differences in the everyday emotional experiences of boys and girls with varying levels of depressive symptoms. Using the Experience Sampling Method, this study investigated the roles of gender and depressive symptomatology in the emotional experiences of a community sample of youth (11-18 year-olds) from the Sloan 500 Family Study. Females with higher levels of depressive symptoms were more likely than females with fewer depressive symptoms and all males to experience strong negative emotions and to attribute the cause of these emotions to other people. These results suggest that emotional reactivity in interpersonal contexts is especially important to understand gender differences in the daily experience of depressive symptoms.

The effective use of self-regulatory strategies, such as selection, optimization, and compensation (SOC) requires resources. However, it is theorized that SOC use is most advantageous for those experiencing losses and diminishing resources. The present study explored this seeming paradox within the context of limitations or constraints due to aging, low cognitive resources, and daily stress in relation to everyday memory problems. We examined whether SOC usage varied by age and level of constraints, and if the relationship between resources and memory problems was mitigated by SOC usage. A daily diary paradigm was used to explore day-to-day fluctuations in these relationships. Participants (n=145, ages 22 to 94) completed a baseline interview and a daily diary for seven consecutive days. Multilevel models examined between- and within-person relationships between daily SOC use, daily stressors, cognitive resources, and everyday memory problems. Middle-aged adults had the highest SOC usage, although older adults also showed high SOC use if they had high cognitive resources. More SOC strategies were used on high stress compared to low stress days. Moreover, the relationship between daily stress and memory problems was buffered by daily SOC use, such that on high-stress days, those who used more SOC strategies reported fewer memory problems than participants who used fewer SOC strategies. The paradox of resources and SOC use can be qualified by the type of resource-limitation. Deficits in global resources were not tied to SOC usage or benefits. Conversely, under daily constraints tied to stress, the use of SOC increased and led to fewer memory problems. PMID:26997686

Hiking in nature is often presented as a yearning for lost harmony premised on an alleged divide between nature as authentically healthy and society as polluted. This paper's aim is to question this strict divide and the strong belief in nature as having an innate health-providing effect, the biophilia hypothesis, by examining what Norwegian families with young children experience when walking in the forest. Twenty-four conversations with families during a hiking trip in the forest were recorded, and the data were analysed with Giorgi's descriptive phenomenological research method. The paper introduces the general descriptive meaning structure of the phenomenon 'family-hiking with young children'. It shows that a hiking trip clears space for the family in their everyday lives which is largely dominated by relations with non-family members at both work and leisure. The families experience that they actively generate a different existence with a sense of here-and-now presences that can strengthen core family relations and also provide the opportunity to pass down experiences that can be recollected and realized by future generations. This experience is complex and constituted by social practices, which indicate that the biophilia hypothesis seems to be an insufficient explanation of why families go hiking in nature. Nature rather represents a peaceful background that allows for the perpetuation of the family as a social institution and the recreation of cohesion in everyday life.

Problem solving is recognized as a skill, helping families of children with disabilities to manage problems in everyday life. Family problem-solving skills may therefore be seen as an important outcome of a child and youth habilitation service. The aim of this pilot feasibility study was to examine the design of a future web-based questionnaire study focusing on problem-solving patterns in relation to resources in families of children with disabilities. The descriptive statistical analyses built on data from 13 families and findings showed an overall satisfactory score distribution for three of the included instruments, whereas two instruments showed floor effects in one third of the items. Findings indicated design problems with data collection related to adapting questionnaires to a web-based survey format and to problems with the stop function that was added. Implementing the main study using web-based surveys needs critical considerations according to the choice of the web tool and the recruitment process.

Although the traits of psychopathic personality (psychopathy) have received extensive attention from researchers in forensic psychology, psychopathology, and personality psychology, the relations of these traits to aspects of everyday functioning are poorly understood. Using a large internet survey of members of the general population (N = 3388), we examined the association between psychopathic traits, as measured by a brief but well-validated self-report measure, and occupational choice, political orientation, religious affiliation, and geographical residence. Psychopathic traits, especially those linked to fearless dominance, were positively and moderately associated with holding leadership and management positions, as well as high-risk occupations. In addition, psychopathic traits were positively associated with political conservatism, lack of belief in God, and living in Europe as opposed to the United States, although the magnitudes of these statistical effects were generally small in magnitude. Our findings offer preliminary evidence that psychopathic personality traits display meaningful response penetration into daily functioning, and raise provocative questions for future research.

This functional magnetic resonance imaging (fMRI) study explored the neural substrates of cognitive dissonance during dissonance "induction." A novel task was developed based on the results of a separate item selection study (n = 125). Items were designed to generate dissonance by prompting participants to reflect on everyday personal experiences that were inconsistent with values they had expressed support for. One experimental condition (dissonance) and three control conditions (justification, consonance, and non-self-related inconsistency) were used for comparison. Items of all four types were presented to each participant (n = 14) in a randomized design. The fMRI analysis used a whole-brain approach focusing on the moments dissonance was induced. Results showed that in comparison with the control conditions the dissonance experience led to higher levels of activation in several brain regions. Specifically dissonance was associated with increased neural activation in key brain regions including the anterior cingulate cortex (ACC), anterior insula, inferior frontal gyrus, and precuneus. This supports current perspectives that emphasize the role of anterior cingulate and insula in dissonance processing. Less extensive activation in the prefrontal cortex than in some previous studies is consistent with this study's emphasis on dissonance induction, rather than reduction. This article also contains a short review and comparison with other fMRI studies of cognitive dissonance.
Historical archaeology may be characterised by an intricate relationship between written sources and material remains. In research focusing on shipwrecks, this often results in descriptions of the events associated with one particular ship. These are narratives written from a historical horizon, where written sources provide the explanation to material remains. The aim of this paper is to show that a combination of material remains and written sources may be used as a departure point for a discussion on social conditions on board merchant ships in a more general sense. The case used is the fluit or fluitship Anna Maria, launched in 1694 and which foundered in Dalarö harbour, Sweden, in 1709. The site is ideal for such a study partly as it has been surveyed archaeologically on several occasions since the 1960s and most recently in 2010, and partly because historical research has been carried out on the related written accounts. Taken together, this material enables a unique opportunity to reconstruct and study the everyday environment on board a large fluitship.

Three experiments examined the attentional components of the popular match-3 casual video game, Bejeweled Blitz (BJB). Attentionally demanding, BJB is highly popular among adults, particularly those in middle and later adulthood. In experiment 1, 54 older adults (Mage = 70.57) and 33 younger adults (Mage = 19.82) played 20 rounds of BJB, and completed online tasks measuring reaction time, simple visual search, and conjunction visual search. Prior experience significantly predicted BJB scores for younger adults, but for older adults, both prior experience and simple visual search task scores predicted BJB performance. Experiment 2 tested whether BJB practice alone would result in a carryover benefit to a visual search task in a sample of 58 young adults (Mage = 19.57) who completed 0, 10, or 30 rounds of BJB followed by a BJB-like visual search task with targets present or absent. Reaction times were significantly faster for participants who completed 30 but not 10 rounds of BJB compared with the search task only. This benefit was evident when targets were both present and absent, suggesting that playing BJB improves not only target detection, but also the ability to quit search effectively. Experiment 3 tested whether the attentional benefit in experiment 2 would apply to non-BJB stimuli. The results revealed a similar numerical but not significant trend. Taken together, the findings suggest there are benefits of casual video game playing to attention and relevant everyday skills, and that these games may have potential value as training tools.

Approximately half of the variation in wellbeing measures overlaps with variation in personality traits. Studies of non-human primate pedigrees and human twins suggest that this is due to common genetic influences. We tested whether personality polygenic scores for the NEO Five-Factor Inventory (NEO-FFI) domains and for item response theory (IRT) derived extraversion and neuroticism scores predict variance in wellbeing measures. Polygenic scores were based on published genome-wide association (GWA) results in over 17,000 individuals for the NEO-FFI and in over 63,000 for the IRT extraversion and neuroticism traits. The NEO-FFI polygenic scores were used to predict life satisfaction in 7 cohorts, positive affect in 12 cohorts, and general wellbeing in 1 cohort (maximal N = 46,508). Meta-analysis of these results showed no significant association between NEO-FFI personality polygenic scores and the wellbeing measures. IRT extraversion and neuroticism polygenic scores were used to predict life satisfaction and positive affect in almost 37,000 individuals from UK Biobank. Significant positive associations (effect sizes <0.05%) were observed between the extraversion polygenic score and wellbeing measures, and a negative association was observed between the polygenic neuroticism score and life satisfaction. Furthermore, using GWA data, genetic correlations of -0.49 and -0.55 were estimated between neuroticism with life satisfaction and positive affect, respectively. The moderate genetic correlation between neuroticism and wellbeing is in line with twin research showing that genetic influences on wellbeing are also shared with other independent personality domains.

Background Subjective well-being as a predictor for later behavior and health has highlighted its relationship to health, work performance, and social relationships. However, the majority of such studies neglect the developmental nature of well-being in contributing to important changes across the transition to adulthood. Methods To examine the potential role of subjective well-being as a long-term predictor of critical life outcomes, we examined indicators of positive and negative affect at age 14 as a predictor of relationship, adjustment, self worth, and career outcomes a decade later at ages 23 to 25, controlling for family income and gender. We utilized multi-informant methods including reports from the target participant, close friends, and romantic partners in a demographically diverse community sample of 184 participants. Results Early adolescent positive affect predicted less relationship problems (less self-reported and partner-reported conflict, greater friendship attachment as rated by close peers), healthy adjustment to adulthood (lower levels of depression, anxiety, and loneliness). It also predicted positive work functioning (higher levels of career satisfaction and job competence) and increased self-worth. Negative affect did not significantly predict any of these important life outcomes. In addition to predicting desirable mean levels of later outcomes, early positive affect predicted beneficial changes across time in many outcomes. Conclusions The findings extend early research on the beneficial outcomes of subjective well-being by having an earlier assessment of well-being, including informant reports in measuring a large variety of outcome variables, and by extending the findings to a lower socioeconomic group of a diverse and younger sample. The results highlight the importance of considering positive affect as an important component of subjective well-being distinct from negative affect. PMID:27075545

This paper addresses, from a socio-legal perspective, the question of the significance of law for the treatment, care and the end-of-life decision making for patients with chronic disorders of consciousness. We use the phrase ‘chronic disorders of consciousness’ as an umbrella term to refer to severely brain-injured patients in prolonged comas, vegetative or minimally conscious states. Based on an analysis of interviews with family members of patients with chronic disorders of consciousness, we explore the images of law that were drawn upon and invoked by these family members when negotiating the situation of their relatives, including, in some cases, the ending of their lives. By examining ‘legal consciousness’ in this way (an admittedly confusing term in the context of this study,) we offer a distinctly sociological contribution to the question of how law matters in this particular domain of social life.

Background Behavioral addiction research has been particularly flourishing over the last two decades. However, recent publications have suggested that nearly all daily life activities might lead to a genuine addiction. Methods and aim In this article, we discuss how the use of atheoretical and confirmatory research approaches may result in the identification of an unlimited list of “new” behavioral addictions. Results Both methodological and theoretical shortcomings of these studies were discussed. Conclusions We suggested that studies overpathologizing daily life activities are likely to prompt a dismissive appraisal of behavioral addiction research. Consequently, we proposed several roadmaps for future research in the field, centrally highlighting the need for longer tenable behavioral addiction research that shifts from a mere criteria-based approach toward an approach focusing on the psychological processes involved.

Entertainment is one of the essential elements in the human society. Entertainment includes “fun” in our everyday life activities, from meeting friends to relaxing at hot spas. Everyday artifacts can become entertaining media if these artifacts and environment are designed to be responsive. This chapter discusses the researches of entertaining artifacts to share how to design responsive artifacts for entertaining experience in our everyday life.

The goals of this article are (a) to describe the daily life of the very old in terms of frequency, duration, variety, and social and physical contexts of activities, and (b) to examine the effects of background variables (e.g., age, sex, residential and marital status, income, and education) on late life activity engagement. A representative sample of 516 adults aged 70-105 was interviewed about their activities using the Yesterday Interview. In contrast to most research on activity engagement, this measurement approach allows for assessment of both the type and context of activities engaged in during the day preceding the interview. The results indicated high frequencies of obligatory activities but also showed substantial time spent in discretionary activities, with television viewing occupying most of the participants' leisure time. Most activities were done alone and at home. In bivariate and multiple regression analyses, age and residential status had the strongest association with activity frequency, duration, and variety; the oldest-old and those residing in long-term care facilities had lower levels of activity engagement. Results are discussed in terms of their relevance for successful aging.

Recent theories of stress reactivity posit that, when stressed, individuals tend to seek out opportunities to affiliate with and nurture others in order to prevent or mitigate the negative effects of stress. However, few studies have tested empirically the role of prosocial behavior in reducing negative emotional responses to stress. The current analyses used daily diary data to investigate whether engaging in prosocial behavior buffered the negative effects of naturally-occurring stressors on emotional well-being. Results showed that on a given day, prosocial behavior moderated the effects of stress on positive affect, negative affect, and overall mental health. Findings suggest that affiliative behavior may be an important component of coping with stress, and indicate that engaging in prosocial behavior might be an effective strategy for reducing the impact of stress on emotional functioning.

Ostracism is a negative interpersonal experience that has been studied primarily in laboratory settings. Moreover, these studies have focused primarily on how people feel when they have been ostracized. The present study extended this research by investigating ostracism as it occurs in daily life, focusing on how people feel about ostracizing someone. Using a method modeled after the Rochester Interaction Record (RIR), for two weeks, 64 participants (adults residing in the community) described what happened each time they ostracized someone. The questions in the diary were based on Williams's (2001) need-threat model of ostracism. Most ostracism episodes were directed toward people of equal status, and participants reported lower levels of belonging but higher levels of control after ostracizing someone. Punitive ostracism was associated with more positive outcomes for the source than when people ostracized someone for other reasons.

Studies show that complaints about being forgetful are weakly correlated with standardized measures of memory impairment. Little attention has been paid to those complaints in a healthy elderly population. Therefore, this qualitative, grounded-theory study investigated the experiences and consequences of becoming forgetful. In-depth interviews with 32 participants were conducted and analyzed. The findings show that forgetfulness became part of daily life through 3 strategies, conceptualized as doing forgetfulness: (1) reducing complexity; (2) creating and maintaining routines; and (3) dealing with feelings of embarrassment and shame. The well-being of people experiencing forgetfulness depended on how successfully they performed the strategies of doing forgetfulness. Gaining insight into this process allows health care professionals to assess the phenomenon early and to individualize counseling and further diagnostic procedures.
In recent years, computerized and non-computerized cognitive remediation programs have been designed for both individual and group settings. We believe, however, that a common misconception lies in considering the efficiency of a cognitive remediation therapy as resulting from the sole use of a computer. This omits that metacognitive skills need also to be trained throughout the remediation phase. RECOS is a theory-based therapeutic approach designed to promote the transfer of cognitive skills to functional improvements. It involves working with one person at a time using both paper/pencil tasks and a set of interactive computer exercises. Paper/pencil exercises are used to promote problem-solving techniques and to help patients to find appropriate suitable strategies. During the following computerized 1-h session, therapists guide participants to the procedural dimension of the action, which refers to knowledge about doing things and relies on retrospective introspection. We assume that each patient has a rich and underestimated procedural knowledge he/she is not aware of. By providing complex and interactive environments, computerized exercises are recommended to bring this knowledge to light. When strategies used by the participant become conscious, conditional knowledge determines when and why to use them in real-life situations.

Women from vulnerable populations encounter challenging circumstances that generate stress and may adversely affect their health. Group prenatal care (GPNC) incorporates features which address social stressors, and has been demonstrated to improve pregnancy outcomes and prenatal care experiences. In this qualitative study, we describe the complex circumstances in the lives of women receiving care in two urban clinics and how GPNC attenuated them. Stressors included problems with transportation and child care, demanding jobs, poverty, homelessness, difficult relationships with partners, limited family support, and frustrating health care experiences. Receiving prenatal care in groups allowed women to strengthen relationships with significant others, gain social support, and develop meaningful relationships with group leaders. By eliminating waits and providing the opportunity to participate in care, GPNC also offered sanctuary from frustrations encountered in receiving individual care. Reducing such stressors may help improve pregnancy outcomes; however, more evidence is needed on mechanisms underlying these effects. PMID:22643609

Food craving refers to an intense desire to consume a specific food and is regularly experienced by the majority of individuals. Yet, there are interindividual differences in the frequency and intensity of food craving experiences, which is often referred to as trait food craving. The characteristics and consequences of trait and state food craving have mainly been investigated in questionnaire-based and laboratory studies, which may not reflect individuals' behavior in daily life. In the present study, sixty-one participants completed the Food Cravings Questionnaire-Trait-reduced (FCQ-T-r) as measure of trait food craving, followed by seven days of Ecological Momentary Assessment (EMA), during which they reported snack-related thoughts, craving intensity, and snack consumption at five times per day. Results showed that 86 percent of reported snacks were high-caloric, with chocolate-containing foods being the most often reported snacks. Individuals with high FCQ-T-r scores (high trait food cravers, HCs) thought more often about high-calorie than low-calorie snacks whereas no differences were found in individuals with low FCQ-T-r scores (low trait food cravers, LCs). Further, the relationship between craving intensity and snack-related thoughts was stronger in HCs than in LCs. Higher craving intensity was associated with more consumption of snacks and again this relationship was stronger in HCs than in LCs. Finally, more snack-related thoughts were related to more frequent consumption of snacks, independent of trait food craving. Thus, HCs are more prone to think about high-calorie snacks in their daily lives and to consume more snack foods when they experience intense cravings, which might be indicative of a heightened responding towards high-calorie foods. Thus, trait-level differences as well as snack-related thoughts should be targeted in dietary interventions.
This commentary supports the argument that there is an increasing tendency to subsume a range of excessive daily behaviors under the rubric of non-substance related behavioral addictions. The concept of behavioral addictions gained momentum in the 1990s with the recent reclassification of pathological gambling as a non-substance behavioral addiction in DSM-5 accelerating this process. The propensity to label a host of normal behaviors carried out to excess as pathological based simply on phenomenological similarities to addictive disorders will ultimately undermine the credibility of behavioral addiction as a valid construct. From a scientific perspective, anecdotal observation followed by the subsequent modification of the wording of existing substance dependence diagnostic criteria, and then searching for biopsychosocial correlates to justify classifying an excessive behavior resulting in harm as an addiction falls far short of accepted taxonomic standards. The differentiation of normal from non-substance addictive behaviors ought to be grounded in sound conceptual, theoretical and empirical methodologies. There are other more parsimonious explanations accounting for such behaviors. Consideration needs to be given to excluding the possibility that excessive behaviors are due to situational environmental/social factors, or symptomatic of an existing affective disorder such as depression or personality traits characteristic of cluster B personalities (namely, impulsivity) rather than the advocating for the establishment of new disorders.

Background The mental health-care system in Sweden, as in many other counties, has its main focus on the reduction of psychiatric symptoms and the prevention of relapses. People diagnosed with schizophrenia often have significant health issues and experience reduced well-being in everyday life. The social imaginary of mental illness as an imbalance of the brain has implications concerning general attitudes in society. The news media are an important source of information on psychiatric disorders and have an important role in cultivating public perceptions and stigma. News media can contribute to the mental illness stigma and place individuals with mental illnesses at risk of not receiving adequate care and support. The aim of this preliminary study was to describe users' experiences of housing support in everyday life. Results The results revealed three themes of housing support, which were needed, but frequently insufficiently fulfilled in the municipality. The three themes were: "Support to Practice Healthy Routines in Daily Life," "Support to Shape Meaningful Contents in Everyday Life," and "Support to Meet Needs of Integrity and Respect." Conclusions The findings support previous studies arguing that current health care and housing support fails to meet basic needs and may lead to significant and unnecessary health risks. Further investigation is needed regarding the links between attitudes to mental illness in society and political and financial principles for health care and housing support for persons with schizophrenia. Further research is needed regarding the role of the media in policymaking concerning health promotion interventions for people diagnosed with schizophrenia.
It is amazing how fascinated people are with the heavens. Who has never admired a sunset or been amazed at a storm? However, even today, a large part of mankind does not understand the celestial and atmospheric phenomena that are part off our daily lives. These natural phenomena are even the subject of myths. This chapter will serve as an introduction, within certain limits, to educators and university students regarding celestial phenomena that are present in our daily lives even though they go un-noticed by most people. Phenomena which are exclusively part of the atmosphere in our planet will not be discussed. The influence of the Earth's atmosphere in scientific observation of the stars is the focus of Chapter 2.

Despite the abundant scholarship on posttraumatic stress disorder (PTSD) and the memoropolitics entailed by testimonial accounts of trauma and genocide, little is known of the everyday experience of trauma survivors and their descendants. Survivor silence is thought to signify only psychological or political repression and the "unspeakability" of traumatic pasts. It is widely accepted that the everyday lives of trauma victims and their descendants entail only the "absence of presence" of the past and the absence of descendant knowledge of that past, while the familial social milieu is thought to foster only the wounds of transmitted PTSD. Contrary to the literature, ethnographic accounts of Holocaust descendants depict the survivor home as embedding the nonpathological presence of the Holocaust past within silent, embodied practices, person-object interaction, and person-person interaction. These silent traces form an experiential matrix of Holocaust presence that sustains familial "lived memory" of the past and transmits tacit knowledge of the past within the everyday private social milieu. The ethnography of silent memory may also provide a tentative model of nontraumatic individual and familial memory work in everyday life.

Twenty adults with learning difficulties (adults) living at home with informal carers, mostly parents, and attending Adult Training Centres (ATCs) were interviewed about their everyday lives and information was also obtained from informal and formal carers. The problem of dealing with the hazards of everyday life emerged as an important theme. The thinking of adults and informal carers could be understood in terms of the moral dimension of hazards, through the distinction between risks, to be calculated, and dangers, to be avoided. Adults and informal carers within families largely agreed in their categorization of hazards but differences were found. In families where the head of the household had had a professional or skilled manual occupation, adults and informal carers were most likely to agree that hazards for the adult were dangers to be avoided. In families which had a history of unemployment or unskilled occupations, adults and informal carers were most likely to treat certain hazards as risks to be taken. The latter families were also less likely to have 2 informal carers. Adults from more risk-tolerant families appeared to be achieving more of their potential in everyday living skills. Formal carers at ATCs were more accepting of risks for adults with learning difficulties than informal carers and there was misunderstanding and conflict between formal and informal carers as a result.

The hypothalamic-pituitary-adrenal (HPA) axis is a psychoneuroendocrine regulator of the stress response and immune system, and dysfunctions have been associated with outcomes in several physical health conditions. Its end product, cortisol, is relevant to fatigue due to its role in energy metabolism. The systematic review examined the relationship between different markers of unstimulated salivary cortisol activity in everyday life in chronic fatigue syndrome (CFS) and fatigue assessed in other clinical and general populations. Search terms for the review related to salivary cortisol assessments, everyday life contexts, and fatigue. All eligible studies (n=19) were reviewed narratively in terms of associations between fatigue and assessed cortisol markers, including the cortisol awakening response (CAR), circadian profile (CP) output, and diurnal cortisol slope (DCS). Subset meta-analyses were conducted of case-control CFS studies examining group differences in three cortisol outcomes: CAR output; CAR increase; and CP output. Meta-analyses revealed an attenuation of the CAR increase within CFS compared to controls (d=-.34) but no statistically significant differences between groups for other markers. In the narrative review, total cortisol output (CAR or CP) was rarely associated with fatigue in any population; CAR increase and DCS were most relevant. Outcomes reflecting within-day change in cortisol levels (CAR increase; DCS) may be the most relevant to fatigue experience, and future research in this area should report at least one such marker. Results should be considered with caution due to heterogeneity in one meta-analysis and the small number of studies.

The aim of this study was to explore how teachers and helpers experience that teacher–student relationship (TSR) is developed and promoted in upper secondary school. We also explored their experiences of qualities of TSR with students with mental health problems or at risk of dropping out. The study used a qualitative and participative approach; key stakeholders were included as co-researchers. Focus group interviews were held with 27 teachers and helpers. A thematic analysis was conducted. The participants’ descriptions of important experiential dimensions of TSR were clustered around four themes: (1) to be recognized as a person with strengths and challenges in everyday life, (2) collaborative relationships between students and teachers, (3) flexible boundaries in the relationship between teachers and students and (4) organization of classes and procedures set the stage for TSR. Collaborative, emotional and contextual qualities were found important to the development of TSR in upper secondary school. Experiences of negative qualities of TSR can contribute to push students out of school. Teachers and helpers experience that TSR may have the potential to play a role in promoting mental health in students’ everyday life. PMID:27707451

A large international literature on how lay citizens make sense of various aspects of science and technology has been generated by investigations which utilise small group methods. Within that literature, focus group and other group-based methods have come to co-exist, and to some extent, hybridise, with the use of small groups in citizen engagement initiatives. In this article, we report on how we drew upon these methodological developments in the design and operationalisation of a policymaking support tool (STAVE). This tool has been developed to gain insight, in a relatively speedy and cost-effective way, into practical details of the everyday lived experience of people's lives, as relating to the sustainability of corresponding practices. An important challenge we faced was how, in Kuhn's terms, to 'translate' between the forms of life corresponding to the world of policymaking and the world of everyday domestic life. We examine conceptual and methodological aspects of how the tool was designed and assembled, and then trialled in the context of active real-world collaborations with policymaking organisations. These trials were implemented in six European countries, where they were used to support work on live policy issues concerned with sustainable consumption.

This dissertation addresses three related tasks and issues in the larger field of science education. The first is to review of the several uses of "everydayness" at play in the science education literature, and in the education and social science literatures more generally. Four broad iterations of everydayness were found in science education, and these were traced and analyzed to develop their similarities, and contradictions. It was concluded that despite tendencies in science education research to suppose a fundamental demarcation either between professional science and everyday life, or between schools and everyday life, all social affairs, including professional science and activity in schools, are continuous with everyday life, and consist fundamentally in everyday, ordinary mundane actions which are ordered and organized by the participants to those social activities and occasions. The second task for this dissertation was to conduct a naturalistic, descriptive study of undergraduate-level physics laboratory activities from the analytic perspective of ethnomethodology. The study findings are presented as closely-detailed analysis of the students' methods of following their instructions and 'fitting' their observed results to a known scientific concept or principle during the enactment of their classroom laboratory activities. Based on the descriptions of students' practical work in following instructions and 'fitting'. The characterization of school science labs as an "experiment-demonstration hybrid" is developed. The third task of this dissertation was to synthesize the literature review and field study findings in order to clarify what science educators could productively mean by "everydayness", and to suggest what understandings of science education the study of everyday action recommends. It is argued that the significance of the 'experiment-demo hybrid' characterization must be seen in terms of an alternate program for science education research, which

Everyday technologies (ETs) like microwave ovens and automatic telephone services as well as assistive technologies (ATs) are often used in the performance of everyday activities. As a consequence, the ability to manage technology is important. This pilot study aimed to clarify the applicability of a model for knowledge translation to support healthcare professionals, to support technology use among older adults with dementia and their significant others. An additional aim was to explore the process of translating the model into practice. The applicability of the model (comprising a one-day course, including introduction and provision of tools, followed by interviews during and after a period of practice) was clarified for 11 healthcare professionals using a constant comparative approach. The content of the model gave the participants an eye-opening experience of technology use among persons with dementia. They also described how they had incorporated the model as a new way of thinking which supported and inspired new investigations and collaborations with colleagues and significant others. This study provided an applicable model of how research knowledge about technology use can be translated into clinical practice and be used by healthcare professionals to support the use of technology for persons with dementia.

Background Parkinson’s disease (PD) is the second most common neurodegenerative disorder after Alzheimer’s disease, and its incidence will increase as the global population ages. Due to the multitude of symptoms, this disease clearly has a significant impact on decreasing quality of life for those with PD. We aimed to evaluate the effect of selected variables on quality of life in people with idiopathic PD treated pharmacologically. Materials and methods This study was conducted among 50 patients with PD aged 47–85 years. The diagnostic survey method was applied to collect data with the use of the authors’ questionnaire and standardized questionnaires, including, Parkinson’s Disease Questionnaire (PDQ), Beck Depression Inventory, Instrumental Activities of Daily Living Scale, and Acceptance of Illness Scale. The results were statistically analyzed. Results Analysis of the study material showed that people who were more self-reliant were characterized by lower intensity of depressive symptoms (ρ=−0.567, P=0), were more likely to accept their illness (ρ=0.611, P=0), and assessed quality of life better in each of the studied domains of the PDQ. Illness acceptance correlated with the occurrence of depressive symptoms (ρ=−0.567, P=0) and significantly affected quality of life. Conclusion Factors such as depression, disease acceptance, and functional capacity have a significant impact on the subjective assessment of quality of life in patients with PD. Evaluation of these factors should be taken into account in the therapeutic process, to minimize their negative impact on quality of life in patients with PD. PMID:28356744
In this article the focus of analysis lies on power relations in everyday life in one of Glasgow's Pauper Lunatic Asylums at the turn of the twentieth century. Taking a sample of patient case files I examine the daily processes of negotiation between inmates and their relatives, physicians, attendants and nurses as well as the poor law administration. Some cases especially exemplify the complex relationships between the actors. They show which opportunities and boundaries existed for "power brokering" for the more powerless. At the same time these cases illustrate the formal and practical limits of enforcement by doctors and nursing staff. Without turning a blind eve to hierarchies and power imbalances the analysis shows that even in settings like "total institutions" power remains volatile. Even there the more powerful actors have to actualize, seize and prevail on a regular basis.

Global life satisfaction has been linked with long-term health advantages, yet how life satisfaction impacts the trajectory of long-term health is unclear. This paper examines one such possible mechanism-that greater life satisfaction confers momentary benefits in daily life that accumulate over time. A community sample of working adults (n = 115) completed a measure of life satisfaction and then three subsequent days of ecological momentary assessment surveys (6 times/day) measuring affect (i.e., emotional valence, arousal), and perceived stress, and also provided salivary cortisol samples. Multilevel models indicated that people with higher (vs. lower) levels of life satisfaction reported better momentary affect, less stress, marginally lower momentary levels and significantly altered diurnal slopes of cortisol. Findings suggest individuals with high global life satisfaction have advantageous daily experiences, providing initial evidence for potential mechanisms through which global life satisfaction may help explain long-term health benefits.

Background Abuse of older people is a serious issue and is associated with an increased risk of morbidity and mortality, and professionals will encounter elderly victims of abuse in all areas of the health care system. An important health determinant is behavioral factors, including coping style, which will impact on how older people manage stress and maintain control in their lives, and thereby protect themselves from abuse. The aim of this study was to explore the coping strategies elderly people abused by their offspring used to manage everyday life. Methods A qualitative approach was used and 14 elderly victims of abuse were interviewed. The interviews were recorded, transcribed, and subjected to qualitative content analysis. Results Five main coping strategies were identified. The main strategy was linked to the role of parent. Another prominent strategy was attitude towards being victimized. Further strategies were associated with hope for a better relationship with offspring in the future, while others felt that they had done the best they could, or that their offspring were no longer their responsibility. The results are discussed in light of theoretical perspectives related to coping and resilience. Conclusion Abuse of older people by their offspring imposes severe stress on victims and challenges the values and beliefs about the caring nature of families. The findings of this study indicate that victims of abuse use a wide range of coping techniques to manage everyday life, and that some strategies help them to maintain their self-respect in their role as parents and find some sort of resilience.

In recent years, a number of studies have used Material Values Scale (MVS) to assess beliefs about importance to own material things. The aims of this study were to validate the MVS scale and to explore the relationships between materialistic values and well-being of Croatian citizens. The study was carried out on a representative sample of N = 1129 Croatian citizens. We used the short 9-item version of the MVS, life satisfaction rating, ratings of two positive (Positive affect) and four negative emotions (Negative affect) over the past month, and demographic variables (age, gender, income). The original dimensionality of the MVS was not confirmed; confirmatory factor analyses yielded two instead of three factors, Happiness and Centrality/Success. When controlled for income, gender and age, the Happiness dimension predicted Life satisfaction and both Positive and Negative affect, indicating that people who believed that the material goods in ones life leads to happiness reported to have lower life satisfaction, lower level of positive affect and higher level of negative affect over the past month. The Centrality/Success dimension was positively related to Positive affect, indicating that the belief that possessions play a central role in enjoyment leads to more frequent experiences of happiness and satisfaction over the past month.

Video recording has become a spontaneous everyday activity for many people, thanks to the video capabilities of modern mobile phones. Internet connectivity of mobile phones enables fluent sharing of captured material even real-time, which makes video an up-and-coming everyday interaction medium. In this article we discuss the effect of the video camera in the social environment, everyday life situations, mainly based on a study where four groups of people used digital video cameras in their normal settings. We also reflect on another study of ours, relating to real-time mobile video communication and discuss future views. The aim of our research is to understand the possibilities in the domain of mobile video. Live and delayed sharing seem to have their special characteristics, live video being used as a virtual window between places whereas delayed video usage has more scope for good-quality content. While this novel way of interacting via mobile video enables new social patterns, it also raises new concerns for privacy and trust between participating persons in all roles, largely due to the widely spreading possibilities of videos. Video in a social situation affects cameramen (who record), targets (who are recorded), passers-by (who are unintentionally in the situation), and the audience (who follow the videos or recording situations) but also the other way around, the participants affect the video by their varying and evolving personal and communicational motivations for recording.

While many aspects of social life possess an emotional component, sociology needs to explore explicitly the part emotions play in producing the social world and human history. This paper turns away from individualistic and anthropocentric emphases upon the experience of feelings and emotions, attending instead to an exploration of flows of 'affect' (meaning simply a capacity to affect or be affected) between bodies, things, social institutions and abstractions. It establishes a materialist sociology of affects that acknowledges emotions as a part, but only a part, of a more generalized affective flow that produces bodies and the social world. From this perspective, emotions are not a peculiarly remarkable outcome of the confluence of biology and culture, but part of a continuum of affectivity that links human bodies to their physical and social environment. This enhances sociological understanding of the part emotions play in shaping actions and capacities in many settings of sociological concern.

HIV-positive men are living long and healthier lives while managing HIV as a chronic illness. Although research has extensively documented the experiences of illness of people living with HIV, dating, marriage, and fatherhood among heterosexual Latino men has not been examined. To address this gap, this study used a qualitative study design to examine patterns and strategies for dating, marriage, and parenthood among 24 HIV-positive heterosexual Puerto Rican men living in Boston. The findings in our study indicate that an HIV diagnosis does not necessarily deter men from having an active sexual life, marrying, or having children. In fact, for some of the men, engaging in these social and life-changing events is part of moving on and normalizing life with HIV; these men planned for, achieved, and interpreted these events in the context of establishing normalcy with HIV. Although the HIV diagnosis discouraged some men from engaging in sexual relations, getting married, or having children, others fulfilled these desires with strategies aimed to reconciling their HIV status in their personal life, including dating or marrying HIV-positive women only. Additional important themes identified in this study include the decision to disclose HIV status to new sexual partners as well as the decision to accept the risk of HIV transmission to a child or partner in order to fulfill desires of fatherhood. Understanding the personal struggles, decision-making patterns, and needs of HIV-positive heterosexual men can aid in designing interventions that support healthy living with HIV.

Maternal environment can influence plant offspring performance. Understanding maternal environmental effects will help to bridge a key gap in the knowledge of plant life cycles, and provide important insights for species' responses under climate change. Here we show that maternal warming significantly affected the early life stages of an invasive thistle, Carduus nutans. Seeds produced by plants grown in warmed conditions had higher germination percentages and shorter mean germination times than those produced by plants under ambient conditions; this difference was most evident at suboptimal germination temperatures. Subsequent seedling emergence was also faster with maternal warming, with no cost to seedling emergence percentage and seedling growth. Our results suggest that maternal warming may accelerate the life cycle of this species via enhanced early life-history stages. These maternal effects on offspring performance, together with the positive responses of the maternal generation, may exacerbate invasions of this species under climate change.

Against the background of demographic change, mobility issues are becoming crucial. Especially for the elderly, daily outdoor activities are essential for participation in social life. This article addresses the question of what extent older people, especially women, are threatened by limited social participation in Berlin's suburbia. The mobility of older women (70+) is characterized by the least number of trips, the shortest distances, and more than 50% walking trips. Besides, many older women are dissatisfied with their residential area. Given the lack of essential facilities, older women have to be considered as disadvantaged in terms of limited social participation.

project is positioned in every-day school-life, the presentation is about practical experiences and given feedback by pupils (class 10 and primary school), teachers (gymnasia and primary school), partners and people. This way, the presentation may also give hints, what are determinants for success and how to overcome barriers in every-day school life and practice. In the future, we are going to found a company leaded by the pupils. Younger classes can book the whole equipment together with tutors. This will lead to the economic aspect of sustainability.

We argue that analyzing everyday memory failures in terms of the "unity of consciousness" can elucidate the bases of such failures. A perfect unity amongst one's mental states is rare. In extreme cases the unity of consciousness can breakdown in dramatic fashion (e.g., in Dissociative Identity Disorder), but such breakdowns also occur in less dramatic ways that affect us in everyday life. For example, disruptions in the unity of consciousness can result in everyday memory failures, such as forgetting to put on a tie for an important formal meeting. After providing some philosophical background into the notions of "unity of consciousness" and "functionalism," we offer preliminary analyses of three examples of everyday memory failure. We then introduce and develop what we call the "unity model" of memory failure and show how it explains the examples. We also describe different ways that unity can break down which, in turn, can lead to memory failure and inappropriate behavior. We then show how slips of action and other kinds of cognitive failures (e.g., memory blocks) differ from everyday memory failures. Finally, we examine alternative models (e.g., Absentmindedness and Multimodal) arguing that the unity model is preferable, and then show how our model is consistent with some experimental results.

Developing a quantitative understanding of the biogeochemical cycles of carbon as they have worked throughout Earth history on various time scales, how they have been affected by biological evolution, and how changes in the carbon content of ocean and atmosphere may have affected climate and the evolution of life are the goals of the research. Theoretical simulations were developed that can be tuned to reproduce such data as exist and, once tuned, can be used to predict properties that have not yet been observed. This is an ongoing process, in which models and results are refined as new data and interpretations become available and as understanding of the global system improves. Results of the research are described in several papers which were published or submitted for publication. These papers are summarized. Future research plans are presented.

Osteoarthritis (OA) mainly affects older populations; however, it is possible that early life factors contribute to the development of OA in later life. The aim of this review is to describe the association between childhood or early adulthood risk factors and knee pain, structural imaging markers and development of knee OA in later life. A narrative overview of the literature synthesising the findings of literature retrieved from searches of computerised databases and manual searches was conducted. We found that only a few studies have explored the long-term effect of childhood or early adulthood risk factors on the markers of joint health that predispose people to OA or joint symptoms. High body mass index (BMI) and/or overweight status from childhood to adulthood were independently related to knee pain and OA in later life. The findings regarding the association between strenuous physical activity and knee structures in young adults are still conflicting. However, a favourable effect of moderate physical activity and fitness on knee structures is reported. Childhood physical activity and performance measures had independent beneficial effects on knee structures including knee cartilage in children and young adults. Anterior knee pain syndrome in adolescence could lead to the development of patellofemoral knee OA in the late 40s. Furthermore, weak evidence suggests that childhood malalignment, socioeconomic status and physical abuse are associated with OA in later life. The available evidence suggests that early life intervention may prevent OA in later life.

Triclocarban (3,4,4'-trichlorocarbanilide; TCC), an antimicrobial used in bar soaps, affects endocrine function in vitro and in vivo. This study investigates whether TCC exposure during early life affects the trajectory of fetal and/or neonatal development. Sprague Dawley rats were provided control, 0.2% weight/weight (w/w), or 0.5% w/w TCC-supplemented chow through a series of 3 experiments that limited exposure to critical growth periods: gestation, gestation and lactation, or lactation only (cross-fostering) to determine the susceptible windows of exposure for developmental consequences. Reduced offspring survival occurred when offspring were exposed to TCC at concentrations of 0.2% w/w and 0.5% w/w during lactation, in which only 13% of offspring raised by 0.2% w/w TCC dams survived beyond weaning and no offspring raised by 0.5% w/w TCC dams survived to this period. In utero exposure status had no effect on survival, as all pups nursed by control dams survived regardless of their in utero exposure status. Microscopic evaluation of dam mammary tissue revealed involution to be a secondary outcome of TCC exposure rather than a primary effect of compound administration. The average concentration of TCC in the milk was almost 4 times that of the corresponding maternal serum levels. The results demonstrate that gestational TCC exposure does not affect the ability of dams to carry offspring to term but TCC exposure during lactation has adverse consequences on the survival of offspring although the mechanism of reduced survival is currently unknown. This information highlights the importance of evaluating the safety of TCC application in personal care products and the impacts during early life exposure.

Many of the decisions and actions in everyday life result from implicit learning processes. Important to psychopathology are, for example, implicit reward-seeking and punishment-avoidant learning processes. It is known that when specific actions get associated with a rewarding experience, such as positive emotions, that this will increase the likelihood that an organism will engage in similar actions in the future. Similarly, when actions get associated with punishing experiences, such as negative emotions, this may reduce the likelihood that the organism will engage in similar actions in the future. This study examines whether we can observe these implicit processes prospectively in the flow of daily life. If such processes take place then we expect that current behaviour can be predicted by how similar behaviour was experienced (in terms of positive and negative affect) at previous measurement moments. This was examined in a sample of 621 female individuals that had participated in an Experience Sampling data collection. Measures of affect and behaviour were collected at 10 semi-random moments of the day for 5 consecutive days. It was examined whether affective experience that was paired with certain behaviours (physical activity and social context) at previous measurements modified the likelihood to show similar behaviours at next measurement moments. Analyses were performed both at the level of observations (a time scale with units of ± 90 min) and at day level (a time scale with units of 24 h). As expected, we found that affect indeed moderated the extent to which previous behaviour predicted similar behaviour later in time, at both beep- and day-level. This study showed that it is feasible to track reward-seeking and punishment-avoidant behaviour prospectively in humans in the flow of daily life. This opens up a new toolbox to examine processes determining goal-oriented behaviour in relation to psychopathology in humans. PMID:26087323

Until recently, most studies investigating the acute relationships between affective and physical feeling states and physical activity were conducted in controlled laboratory settings, whose results might not translate well to everyday life. This review was among the first attempts to synthesize current evidence on the acute (e.g., within a few hours) relationships between affective and physical feeling states and physical activity from studies conducted in free-living, naturalistic settings in non-clinical populations. A systematic literature search yielded 14 eligible studies for review. Six studies tested the relationship between affective states and subsequent physical activity; findings from these studies suggest that positive affective states were positively associated with physical activity over the next few hours while negative affective states had no significant association. Twelve studies tested affective states after physical activity and yielded consistent evidence for physical activity predicting higher positive affect over the next few hours. Further, there was some evidence that physical activity was followed by a higher level of energetic feelings in the next few hours. The evidence for physical activity reducing negative affect in the next few hours was inconsistent and inconclusive. Future research in this area should consider recruiting more representative study participants, utilizing higher methodological standards for assessment (i.e., electronic devices combined with accelerometry), reporting patterns of missing data, and investigating pertinent moderators and mediators (e.g., social and physical context, intensity, psychological variables). Knowledge gained from this topic could offer valuable insights for promoting daily physical activity adoption and maintenance in non-clinical populations.

The present experiment was designed to establish the effects of acts of kindness and acts of novelty on life satisfaction. Participants aged 18-60 took part on a voluntary basis. They were randomly assigned to perform either acts of kindness, acts of novelty, or no acts on a daily basis for 10 days. Their life satisfaction was measured before and after the 10-day experiment. As expected, performing acts of kindness or acts of novelty resulted in an increase in life satisfaction.
People who experience mental illness can be viewed as either fundamentally different than, or fundamentally like, everyone else in society. Recovery-oriented mental health systems focus on commonality. In practice, this involves an orientation toward supporting everyday solutions for everyday problems rather than providing specialist treatments for mental illness-related problems. This change is evident in relation to help offered with housing, employment, relationships, and spirituality. Interventions may contribute to the process of striving for a life worth living, but they are a means, not an end. Mental health systems that offer treatments in support of an individual's life goals are very different than those that treat patients in their best interests. The strongest contribution of mental health services to recovery is to support everyday solutions to everyday problems.

Religious beliefs have had a key role in shaping local responses to HIV and AIDS. As the world's largest Catholic country, Brazil is no exception. Yet little research has been conducted to document how the religious doctrine is enacted in practice among its lay leaders and followers. In this article, we present ethnographic research from Recife, Brazil, conducted to understand the way in which religious doctrines are interpreted on a local level. Contextualized within the sociology of contemporary Brazilian Catholicism, we draw on interviews with clergy members, lay leaders and parishioners in order to discuss how the Catholic Church's vision of sexuality translates into the everyday lives of its followers by. We explore the disjuncture between the Catholic ideals of fidelity and delaying sex until marriage with the everyday reality of the Church's followers, highlighting the role that gender plays in defining sexual roles and expectations. We conclude posing questions for future research and HIV prevention strategies considering the formal institutional response of the Brazilian Catholic Church to AIDS on one hand, and the social and cultural contexts in which Catholics live their daily lives on the other.

Background Chronic diseases endanger not only physical health but also psychological and social health of patient. Thus, evaluation of such patients for psychological treatment decisions is very important. Method This is a descriptive study that was performed with 50 chronic patients (ischemic heart disease) selected from Valiasr and Mousavi at cardiac wards in Zanjan Province. They were given three types of questionnaire: demographic, WHOQOL, and Zung depression and anxiety index. The information was statically analyzed by frequency chart, central indexes, dispersion, Chi-Square and t tests, Pearson’s correlation index (P < 0.05). Results The average of quality of life in all patients were calculated as was respectively 12.19, 11.98, 12.08, and 12.4 in physical, psychological, social and environmental domains respectively, 68 percent of total number of the patients had various degrees of anxiety and 78 percent of them had various degrees of depression. There was a significant relationship between the life quality average in all domains and anxiety intensity and depression intensity (P < 0.05) and there was a significant relationship between life quality average in all domains and income (P < 0.05). Conclusion As the level of depression and anxiety goes up, quality of life decreases pointing out that they have a reverse relationship. Depression and anxiety are one of the most significant factors of quality of life among other variables. Regarding specific conditions of the treatment, it is necessary to pay special attention to psychological aspects.

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.

Our senses have developed as an answer to the world we live in (Gibson, 1966) and so have the forms of memory that accompany them. All senses serve different purposes and do so in different ways. In vision, where orientation and object recognition are important, memory is strongly linked to identification. In olfaction, the guardian of vital functions such as breathing and food ingestion, perhaps the most important (and least noticed and researched) role of odor memory is to help us not to notice the well-known odors or flavors in our everyday surroundings, but to react immediately to the unexpected ones. At the same time it provides us with a feeling of safety when our expectancies are met. All this happens without any smelling intention or conscious knowledge of our expectations. Identification by odor naming is not involved in this and people are notoriously bad at it. Odors are usually best identified via the episodic memory of the situation in which they once occurred. Spontaneous conscious odor perception normally only occurs in situations where attention is demanded, either because the inhaled air or the food smell is particularly good or particularly bad and people search for its source or because people want to actively enjoy the healthiness and pleasantness of their surroundings or food. Odor memory is concerned with novelty detection rather than with recollection of odors. In this paper, these points are illustrated with experimental results and their consequences for doing ecologically valid odor memory research are drawn. Furthermore, suggestions for ecologically valid research on everyday odor memory and some illustrative examples are given. PMID:24575059

Objectives The aim of this study was to determine if a gynecologic cancer patient's comfort level discussing end-of-life care issues with her caregivers is related to her death anxiety level. Materials/Methods Gynecologic oncology clinic patients were asked to rate their degree of agreeability with 4 statements regarding comfort level discussing end-of-life care issues. Participants also completed the Hoge's Intrinsic Religiosity Scale and Templer's Death Anxiety Scale. Results Four hundred one surveys were distributed. One hundred twenty-nine patients participated, with a response rate of 32.2%. The median age of the sample was 55 years. Most patients were white (72.9%), married (58.9%), and Christian (85.3%). Most patients had ovarian cancer (40.4%). Of the 74 patients who knew their cancer stage, 59% had been diagnosed with advanced (stage III-IV) disease. Thirty-three percent were currently in remission, and 17% had recurrent disease. Of all patients surveyed, 32.6% were currently receiving treatment. Chemotherapy was the most common treatment (62% of those being treated). Higher level of comfort discussing end-of-life care topics such as do-not-resuscitate orders with family members was significantly associated with decreased death anxiety (P = 0.008 and P = 0.001). There was no significant association between comfort level when patients discussed do-not-resuscitate orders with physicians and patients' death anxiety (P = 0.14). After controlling for age, race, marital status, education level, current treatment status, and religiosity, linear regression analysis demonstrated that the relationship between a patient's increased comfort level when discussing end-of-life care topics with family members and decreased death anxiety remained statistically significant (P = 0.005 and P = 0.001). Conclusions Conversations regarding goals of treatment are an important component of caring for cancer patients. Death anxiety may contribute to decreased communication between

Early life stress (ELS) can alter brain function and increases the risk of major depressive disorder (MDD) in later life. This study investigated whether ELS contributes to differences in regional brain activity between MDD patients and healthy controls (HC), as measured by amplitude of low-frequency fluctuation (ALFF)/fractional (f)ALFF. Eighteen first-episode, treatment-naïve MDD patients and HC were assessed with the Childhood Trauma Questionnaire and resting-state functional magnetic resonance imaging. We compared ALFF/fALFF between MDD patients and HC, with or without controlling for ELS, and determined whether ELS level was correlated with regional brain activity in each group. After regressing out ELS, we found that ALFF increased in bilateral amygdala and left orbital/cerebellum, while fALFF decreased in left inferior temporal and right middle frontal gyri in MDD patients relative to controls. ELS positively correlated with regional activity in the left cerebellum in MDD and in the right post-central/inferior temporal/superior frontal cingulate, inferior frontal gyrus and bilateral cerebellum in HC. Our findings indicate that there is only very limited region showing correlation between ELS and brain activity in MDD, while diverse areas in HC, suggesting ELS has few impacts on MDD patients.

Background. The affective profiles model categorizes individuals as self-fulfilling (high positive affect, low negative affect), high affective (high positive affect, high negative affect), low affective (low positive affect, low negative affect), and self-destructive (low positive affect, high negative affect). The model has been used extensively among Swedes to discern differences between profiles regarding happiness, depression, and also life satisfaction. The aim of the present study was to investigate such differences in a sample of residents of the USA. The study also investigated differences between profiles with regard to happiness-increasing strategies. Methods. In Study I, 900 participants reported affect (Positive Affect Negative Affect Schedule; PANAS) and happiness (Happiness-Depression Scale). In Study II, 500 participants self-reported affect (PANAS), life satisfaction (Satisfaction With Life Scale), and how often they used specific strategies to increase their own happiness (Happiness-Increasing Strategies Scales). Results. The results showed that, compared to the other profiles, self-fulfilling individuals were less depressed, happier, and more satisfied with their lives. Nevertheless, self-destructive individuals were more depressed, unhappier, and less satisfied than all other profiles. The self-fulfilling individuals tended to use strategies related to agentic (e.g., instrumental goal-pursuit), communal (e.g., social affiliation), and spiritual (e.g., religion) values when pursuing happiness. Conclusion. These differences suggest that promoting positive emotions can positively influence a depressive-to-happy state as well as increasing life satisfaction. Moreover, the present study shows that pursuing happiness through strategies guided by agency, communion, and spirituality is related to a self-fulfilling experience described as high positive affect and low negative affect.

The purpose was to investigate positive and negative affect, life satisfaction, and coping with stress in relation to attachment styles. Undergraduate students (N=421) completed the Relationship Scales Questionnaire, the Positive and Negative Affect Scale, the Satisfaction With Life Scale, and the Coping with Stress Scale. Results indicated that secure attachment style was the unique predictor of positive affect while fearful and preoccupied attachment styles significantly predicted negative affect. Regarding life satisfaction, a positive correlation with secure attachment style and a negative correlation with fearful and preoccupied styles were seen. However, the unique predictor of life satisfaction was preoccupied attachment style. In terms of coping with stress, there was no significant association between attachment variables and avoidance coping style, but significant links were observed between problem-focused coping and dismissing, and fearful and preoccupied attachment styles.

Research on meaning in life has generally focused on global meaning judgments. This study examined how people's daily experiences, represented by events that occur in daily life, influence their perceived sense of meaning on a daily basis. One hundred sixty-two college students completed daily reports for 2 weeks. We examined the relationships among daily social and achievement events, daily positive and negative affect, and daily meaning in life. In addition, we tested the possible moderating influence of depressive symptoms on these relationships. Positive daily social and achievement events were related to greater daily meaning, above and beyond the contributions of daily positive and negative affect. Negative social and achievement events were related to less daily meaning, and negative achievement events covaried with daily meaning above and beyond positive and negative affect. Depression moderated the relationships between positive events and meaning, such that people who reported more depressive symptoms had greater increases in daily meaning in response to positive social and achievement events than individuals who reported fewer symptoms. These findings suggest the important role that daily events may play in fluctuations in people's affective experiences and sense of meaning in life.

[Purpose] This study examined the quality of life of homebound elderly hemiparetic stroke patients with cognitive impairment and the factors affecting their quality of life. [Subjects and Methods] The subjects of the study were 17 home-based elderly hemiparetic stroke patients with cognitive impairment (8 males and 9 females, average age: 76.3 ± 10.5 years old). Their physical and psychological conditions, quality of life and other items were investigated. Nishimura’s Mental State Scale for the Elderly was used for the cognitive impairment assessment. The Functional Independence Measure was used to assess activities of daily living, and the Japanese Quality of Life Inventory for the Elderly with Dementia was used to assess quality of life. [Results] The subjects’ quality of life was affected by their cognitive impairment level and independence of activities of daily living. However, no correlations were observed between the quality of life of the homebound elderly hemiparetic stroke patients with cognitive impairment, age, gender or care-need level. [Conclusion] In order to improve the quality of life of homebound elderly hemiparetic stroke patients with cognitive impairment, assistance helping them to maintain their cognitive abilities and on-going rehabilitation for improving activities of daily living independence are required.

Lung cancer is a disease with many biomedical and psychological symptoms. The diagnosis and treatment of lung cancer induces adverse effects. Having an inoperable lung cancer there are few possibilities of being cured. Management of patients with inoperable disease is directed at relieving local or systemic symptoms. The purpose of this study is to describe how it affects the patients' life situation and quality of life. Data was collected by qualitative interviews where the patient's lived experiences were articulated. Twenty-three Swedish patients diagnosed and starting palliative treatment for inoperable lung cancer were interviewed. The interviews were audio-taped and transcribed verbatim. Data were interpreted trough interpretive phenomenology. Six themes were identified that were important for the informants' experience of their life situation and quality of life. The themes were: Experience of uncertainty; including time of waiting and thoughts, experience of hope; about a prolonged life, network as support; being treated as the person they are thoughts of death; is there time to conclude their lives?, feelings of shame and guilt; they have caused the disease by themselves and next of kin reactions; sadness, guilt, worries and anger. These six themes gave a structure presenting the essence: Living as usual. Maintaining independency and integrity were important, as well as maintaining status, being treated as the person they always had been and that they experience that they had a meaning to fulfill in life. They were living as usual. The findings of this study point out the importance of improving the care of people afflicted with lung cancer, as well as promoting support for the next of kin, since they are significantly important for these patients' experiences of quality of life. This knowledge and understanding will be useful for development of interventions and guidelines for treatment.

Childhood antibiotic exposure has been recently linked with increased risk of metabolic disease later in life. A better understanding of this association would potentially provide strategies to reduce the childhood chronic disease epidemic. Therefore, we explored the underlying mechanisms using a swine model that better mimics human infants than rodents, and demonstrated that early life antibiotic exposure affects glucose metabolism 5 weeks after antibiotic withdrawal, which was associated with changes in pancreatic development. Antibiotics exerted a transient impact on postnatal gut microbiota colonization and microbial metabolite production, yet changes in the expression of key genes involved in short-chain fatty acid signaling and pancreatic development were detected in later life. These findings suggest a programming effect of early life antibiotic exposure that merits further investigation. PMID:28150721

The hedonic view on well-being, consisting of both cognitive and affective aspects, assumes that through maximizing pleasurable experiences, and minimizing suffering, the highest levels of well-being can be achieved. The eudemonic approach departs from the concept of a good life that is not just about pleasure and happiness, but involves developing one-self, being autonomous and realizing one's potential. While these approaches are often positioned against each other on theoretical grounds, this paper investigates the empirical plausibility of this two dimensional view on subjective well-being. The interrelations between common measures such as the General Health Questionnaire, the CES-D inventory of depressive symptoms, the satisfaction with life scale and the eudemonic CASP scale are examined in a confirmatory factor analysis framework using the third wave of the English Longitudinal Study of Ageing (ELSA). A multidimensional structure of well-being, distinguishing cognitive, affective and eudemonic well-being, is shown to be the best fitting empirical solution. This three dimensional second order structure is neutral to gender in its measurement. A lower influence of feeling energetic on self-actualisation, and of somatic symptoms of depression on affective well-being was noted for respondents in the fourth age in comparison to respondents in the third age. These small measurement artefacts underline that somatic symptoms of later life depression should be distinguished from mood symptoms. Two main social facts are confirmed when we compare the different forms of well-being over gender and life stage: men tend to have a higher level of well-being than women, and well-being is lower in the fourth age than in the third age. Although the three measures are very closely related, with high correlations between .74 and .88, they each have their specific meaning. While affective and cognitive well-being emphasize the use of an internal yardstick to measure well

Previous research has shown that being affectively unstable is an indicator of several forms of psychological maladjustment. However, little is known about the mechanisms underlying affective instability. Our research aims to examine the possibility that being prone to extreme fluctuations in one’s feelings is related to maladaptive emotion regulation. We investigated this hypothesis by relating affective instability, assessed in daily life using the experience sampling method, to self-reported emotion regulation strategies and to parasympathetically mediated heart rate variability (HRV), a physiological indicator of emotion regulation capacity. Results showed that HRV was negatively related to instability of positive affect (as measured by mean square successive differences), indicating that individuals with lower parasympathetic tone are emotionally less stable, particularly for positive affect.

An analysis and comparison of everyday life and the domain of science reveals significant differences in their goals and in the cognitive means used to attain these goals. Students' lack of awareness of these differences can lead to pervasive learning difficulties in their study of science. Thus many students (a) have erroneous conceptions of scientific goals, (b) import goals and ways of thinking which are effective in everyday life but inadequate in science, and (c) devise ways of thinking ill suited to science. Additional complications arise because science taught in schools often differs both from actual science and from everyday life. Students' learning difficulties are thus increased because scientific goals are distorted and scientific ways of thinking are inadequately taught. The preceding analysis suggests some empirical investigations and instructional improvements.

It has recently been demonstrated that as the ratio of protein to carbohydrate (P:C) in the diet declines, life span increases in Drosophila. Here we explored how extremely low dietary ratios of protein to carbohydrate affected longevity and a selection of variables associated with functional senescence. An increase in P:C ratio from 1:57 to 1:20 shortened life span by increasing age-dependent mortality; whereas a further decline in P:C from 1:57 to 1:95 caused a modest decrease in life span. Female flies consuming the 1:20 and 1:38 diets laid more eggs than those consuming the lower P:C diets. Flies fed diets with higher ratios were more resistant to heat stress. Flies consuming the diets with lowest P:C ratios needed more time to restore activity after paralysis. Our study has therefore extended to very low P:C ratios available data demonstrating that dietary P:C ratio affects life span, fecundity and heat stress resistance, with fecundity and heat stress responses showing the opposite trend to life span.

Previously institutionalized older patients with schizophrenia show changes in cognitive and functional capacity over time. This study examined changes in real-world functioning in a sample of people with schizophrenia who varied in their history of long-term institutionalization and related changes in real world functioning to changes in cognition and functional capacity over the follow-up period. Older patients with schizophrenia (n=111) were examined with assessments of cognitive functioning, functional capacity, clinical symptoms, and everyday functioning. They were then followed up to 45 months and examined up to two times. Mixed-model regression was used to examine changes in real-world functioning in social, everyday living, and vocational domains over the follow-up period and identify potential predictors of change. Everyday functioning worsened over time in all three domains. Although length of longest hospitalization predicted worsening, this influence was eliminated when the course of functional capacity was used to predict the course of everyday functioning. For both vocational and everyday living domains, as well as the composite score on functional status, worsening in performance based measures of everyday functioning and social competence predicted worsening in real world functioning. Changes in negative symptoms further predicted worsening in the everyday living domain. Worsening in everyday functioning is found in people with schizophrenia and those with a history of greater chronicity and severity of illness seem more affected. These influences seem to be expressed through worsening in the ability to perform everyday functional skills. Potential causes of these changes and implications for reducing these impairments are discussed. PMID:25045625

Objective Assessment of daily functions affected by cognitive loss in prodromal Huntington disease (HD) is necessary in practice and clinical trials. We evaluated baseline and longitudinal sensitivity of the Everyday Cognition (ECog) scales in prodromal HD and compared self- and companion-ratings. Method Everyday cognition was self-assessed by 850 participants with prodromal HD and 768 companions. We examined internal structure using confirmatory factor analysis (CFA) on baseline data. For longitudinal analysis, we stratified participants into Low, Medium, and High disease progression groups. We examined ECog scores for group differences and participant-and-companion differences using linear mixed effects regression (LMER). Comparison with the Total Functional Capacity (TFC) scale was made. Results CFA revealed good fit of a 5-factor model having a global factor (total score), and sub factors (subscales) of memory, language, visuospatial perception, and executive function. At study entry, participants and companions in the Medium and High groups reported significantly worsened everyday cognition as well as significant functional decline over time. Losses became more pronounced and participant and companion ratings diverged as individuals progressed. TFC showed significant functional loss over time in the High group but not in the Medium group. Conclusions Disease progression is associated with reduced self- and companion-reported everyday cognition in prodromal HD participants who are less than 13 years to estimated motor onset. Our findings suggest companion ratings are more sensitive than participants’ for detecting longitudinal change in daily cognitive function. ECog appears more sensitive to specific functional changes in the prodrome of HD than the TFC. PMID:25000321

Stressful life events are now established as risk factors for the onset of affective disorder but few studies have investigated time-varying exposure effects. Discrete (grouped) time survival methods provide a flexible framework for evaluating multiple time-dependent covariates and time-varying covariate effects. Here, we use these methods to investigate the time-varying influence of life events on the onset of affective disorder. Various straightforward time-varying exposure models are compared, involving one or more (stepped) time-dependent covariates and time-dependent covariates constructed or estimated according to exponential decay. These models are applied to data from two quite different studies. The first, a small scale interviewer-based longitudinal study (n = 180) concerned with affective disorder onset following loss (or threat of loss) event experiences. The second, a questionnaire assessment as part of an ongoing population study (n = 3353), provides a history of marital loss events and of depressive disorder onset. From the first study the initial impact of loss events was found to decay with a half-life of 5 weeks. Psychological coping strategy was found to modify vulnerability to the adverse effects of these events. The second study revealed that while men had a lower immediate risk of disorder onset following loss event experience their risk period was greater than for women. Time-varying exposure effects were well described by the appropriate use of simple time-dependent covariates.

The affective profiles model distinguishes between individuals who are self-fulfilling (high positive affect, low negative affect), high affective (high positive affect, high negative affect), low affective (low positive affect, low negative affect), and self-destructive (low positive affect, high negative affect). The literature shows that the affective profiles model has been used with Swedish people in particular in order to determine differences among profiles in relation to life satisfaction, psychological well-being, self-esteem, and optimism. The present research investigated these differences in Italian high school students. Two studies were conducted: the first with 156 Italian high school students and the second with 148 Italian high school students. The first study analyzed differences among affective profiles with regard to life satisfaction and psychological well-being while the second study analyzed differences among affective profiles with regard to self-esteem and optimism. In the first study, the Positive and Negative Affect Schedule (PANAS), the Satisfaction with Life Scale, and the Meaningful Life Measure were administered to the participants. In the second study, the PANAS, the Self-Esteem Scale, the Life Orientation Test-revised were administered to the participants. The results of the first study showed that, with respect to the other profiles, the self-fulfilling participants had greater life satisfaction and psychological well-being. The results of the second study showed that, with respect to the other profiles, the self-fulfilling participants had higher self-esteem and optimism. These results revealed differences among affective profiles regarding life satisfaction, psychological well-being, self-esteem, and optimism in the Italian context as well thereby offering new possibilities for cross-cultural research and for enhancing self-fulfilling profiles.

Exposure to stressors can affect an organism's physiology and behavior as well as that of its descendants (e.g. through maternal effects, epigenetics, and/or selection). We examined the relative influence of early life vs. transgenerational stress exposure on adult stress physiology in a species that has populations with and without ancestral exposure to an invasive predator. We raised offspring of eastern fence lizards (Sceloporus undulatus) from sites historically invaded (high stress) or uninvaded (low stress) by predatory fire ants (Solenopsis invicta) and determined how this different transgenerational exposure to stress interacted with the effects of early life stress exposure to influence the physiological stress response in adulthood. Offspring from these high- and low-stress populations were exposed weekly to either sub-lethal attack by fire ants (an ecologically relevant stressor), topical treatment with a physiologically-appropriate dose of the stress-relevant hormone, corticosterone (CORT), or a control treatment from 2 to 43weeks of age. Several months after treatments ended, we quantified plasma CORT concentrations at baseline and following restraint, exposure to fire ants, and adrenocorticotropic hormone (ACTH) injection. Exposure to fire ants or CORT during early life did not affect lizard stress physiology in adulthood. However, offspring of lizards from populations that had experienced multiple generations of fire ant-invasion exhibited more robust adult CORT responses to restraint and ACTH-injection compared to offspring from uninvaded populations. Together, these results indicate that transgenerational stress history may be at least as important, if not more important, than early life stress in affecting adult physiological stress responses.

The way in which attachment styles are expressed in the moment as individuals navigate their real-life settings has remained an area largely untapped by attachment research. The present study examined how adult attachment styles are expressed in daily life using experience sampling methodology (ESM) in a sample of 206 Spanish young adults. Participants were administered the Attachment Style Interview (ASI) and received personal digital assistants that signaled them randomly eight times per day for 1 week to complete questionnaires about their current experiences and social context. As hypothesized, participants' momentary affective states, cognitive appraisals, and social functioning varied in meaningful ways as a function of their attachment style. Individuals with an anxious attachment, as compared with securely attached individuals, endorsed experiences that were congruent with hyperactivating tendencies, such as higher negative affect, stress, and perceived social rejection. By contrast, individuals with an avoidant attachment, relative to individuals with a secure attachment, endorsed experiences that were consistent with deactivating tendencies, such as decreased positive states and a decreased desire to be with others when alone. Furthermore, the expression of attachment styles in social contexts was shown to be dependent upon the subjective appraisal of the closeness of social contacts, and not merely upon the presence of social interactions. The findings support the ecological validity of the ASI and the person-by-situation character of attachment theory. Moreover, they highlight the utility of ESM for investigating how the predictions derived from attachment theory play out in the natural flow of real life.

Executive functions involve control processes such as goal-oriented planning, flexible strategy generation, sustaining set maintenance, self-monitoring, and inhibition. Executive functions during everyday events (EFEEs) are distinct from those measured under laboratory settings; the former can be severely impaired while the latter remain intact. Non-routine everyday problems due to executive dysfunctions affect individual functioning in everyday life and are of great clinical interest. Despite the importance of anatomical bases underlying better EFEEs, such bases have never been investigated among non-clinical samples. Using voxel-based morphometry to measure regional gray matter volume (rGMV) and regional white matter volume (rWMV) and diffusion tensor imaging to determine fractional anisotropy values, we identified the anatomical correlates of better EFEEs using the Dysexecutive Questionnaire in 303 normal young subjects (168 men and 135 women). Better EFEEs were associated with a smaller rGMV in the orbitofrontal cortex (OFC) spread across Brodmann areas (BA) 25, 11, and 12 and larger rWMV in the WM area of OFC adjacent to BA 11. Furthermore, individual EFEEs were positively associated with rWMV in the temporal areas, primarily the inferior longitudinal fasciculus and inferior fronto-occipital fasciculus, the latter of which connects OFC and posterior regions. Thus, our findings suggest that brain structures involving OFC, together with other regions, contribute to the maintenance of effective EFEEs among non-clinical subjects.

The present publication discusses the following hypotheses: 1) With a continual increase in the state of scientific knowledge and the hygienic risk factors (infectious diseases, multi-resistant pathogens, age structure of the population with increasing risk of infection, etc.) a hygiene behaviour with increasing deficits develops. 2) Essential hygiene behaviour is blocked by irrational psychological defensive strategies: (a) hygiene biases (childhood illnesses as stabilisers for health development; hygiene as a health risk; overrating chemical-physical environmental risks as e.g. triggers for causing illness), (b) one's own personal risk balance: objective risks are minimised in the likelihood of their occurrence. 3) Hygiene education: the development of a prophylaxis-oriented lifestyle lies (a) in the model behaviour of parents, (b) in conveying the reasons for sensible behaviour, (c) in continually checking behaviour and (d) in appropriate sanctioning when deficits are perceived. 4) Conveying hygiene knowledge is an essential but inadequate prerequisite for corresponding hygiene behaviour. Motivators for hygiene behaviour are the following: (a) parental model behaviour and development of personal responsibility, (b) establishing simple, short, understandable and--for specific risk areas--specific rules of behaviour, (c) conveying hygiene information in the language of the target group, (d) integrating hygiene behaviour in a preventive lifestyle which must be inspired by the quality of life and well-being occurring and being experienced.

This scoping review identifies and describes relevant studies related to the evidence published on life experiences and perceived social support of people affected by Crohn's disease. Twenty-three studies were definitely selected and analyzed for the topics explored. The overall findings show patients' needs and perceptions. There is a lack of evidence about patients' perceived needs as well as the understanding of social support that has contributed to improve their life experiences with that chronic illness. Lack of energy, loss of body control, body image damaged due to different treatments and surgeries, symptoms related to fear of disease, feeling burdened loss related to independence, and so on are some of the concerns with having to live with those affected by the Crohn. To underline those experiences through this scoping review provides valuable data for health care teams, especially for the nursing profession, considered by those affected as one of the main roles along the whole pathological process. This review provides the basis for developing broader research on the relatively underexplored topics and consequently improves specific programs that could address patients' needs.
This study used longitudinal data to examine the effects of spousal illness on depressive symptoms among middle-aged and older married individuals and the extent to which the adverse effects of illness in a spouse were mitigated by 2 psychological resources, mastery and self-esteem. Using 1,704 married participants who were 51 years of age on average, depressive symptoms were compared in 4 groups varying in their experience of spousal health transitions: those whose spouse remained ill at T1 and T2, those whose spouse declined in health from T1 to T2, those whose spouse's health improved from T1 to T2, and those whose spouse remained healthy at both time points. Mixed analyses of covariance showed that, as hypothesized, having a spouse who became or remained ill over time was linked to greater depressed affect by T2, whereas having a spouse improve in health was associated with a decline in depressive symptomatology. Moderated regression analyses indicated that while higher mastery and self-esteem were linked to lower depressed affect in general, these resources were especially protective against depressed affect for those whose spouse remained ill at both time points. These findings are at the intersection of life course theory and the stress process model highlighting the contextual forces in and the interconnectedness of individual development as well as the plasticity and resilience evident in adaptation to stress during mid and late life.

In recent years, a number of studies have demonstrated that stress and mental health problems have increased among adolescents and especially among girls, although little is still known concerning what girls experience in their everyday lives. The aim of this study was to describe the phenomenon of teenage girls’ everyday lives, as experienced by the girls themselves. A phenomenological approach of reflective lifeworld research was used, and the findings are based on eight qualitative interviews with girls aged 13–16 years. The essence of teenage girls’ everyday lives as experienced by the girls themselves can be described as consciousness regarding demands and unfairness and regarding the importance of connectedness and security. The girls are aware of the demands of appearance and success, and they are conscious of the gender differences in school and in the media that affect them. The girls are also conscious about the meaning of connectedness with friends and family, as well as the importance of the security of their confidence in friends and feeling safe where they stay. If teenage girls feel connected and secure, protective factors in the form of manageability and meaningfulness can act as a counterweight to the demands and unfairness of everyday life. For professionals who work with teenage girls, the results from this study can be important in their work to support these girls. PMID:26084273

Migratory birds may improve fecundity by moving to seasonal breeding areas, but may also suffer higher mortality rates as a cost of movement. However, the covariation among seasonality, migratoriness and life histories should change between species if their ecological features affect site-tenacity, survival or fecundity. In frugivorous birds, for instance, wandering in search of fruits may trigger broader migrations than territorial defence, and also may improve nonbreeding survival by preventing food shortages that eventually happen in discrete territories. We studied the variation in spatio-temporal distribution, life expectancy and fecundity in robins ( Erithacus rubecula) and blackcaps ( Sylvia atricapilla) distributed in three Iberian regions with a low, mid or high degree of environmental seasonality. In the Iberian Peninsula, robins and blackcaps are the two most intensive frugivores in winter; however, robins are territorial while blackcaps track fruit abundance among habitat patches. In the most seasonal area, robins and blackcaps decreased abundance in winter and showed a lower breeding-site tenacity, a shorter life expectancy and a larger clutch size. However, blackcaps tended to be more migratory than robins in all regions. Despite their stronger migratory behaviour, blackcaps showed a longer life expectancy and a smaller clutch size than robins in all regions. In robins, winter territoriality could decrease nonbreeding survival but also improve fecundity, because survivors are dominant and hence more efficient breeders. In blackcaps, however, the use of the most profitable habitat patches could improve nonbreeding survival, thereby allowing a similar recruitment than in robins with a lower reproductive investment. These results support that regional-scale changes in seasonality may affect migratory behaviour and hence the tradeoff between reproduction and survival in birds, doing so differently depending on the idiosyncrasy of each species.

Early-life deficiency of the serotonin transporter (SERT) gives rise to a wide range of psychiatric-relevant phenotypes; however, the molecular and cellular targets of serotonin dyregulation during neural circuit formation remain to be identified. Interestingly, migrating cortical interneurons (INs) derived from the caudal ganglionic eminence (CGE) have been shown to be more responsive to serotonin-mediated signalling compared with INs derived from the medial ganglionic eminence (MGE). Here we investigated the impact of early-life SERT deficiency on the migration and positioning of CGE-derived cortical INs in SERT-ko mice and in mice exposed to the SERT inhibitor fluoxetine during the late embryonic period. Using confocal time-lapse imaging and microarray-based expression analysis we found that genetic and pharmacological SERT deficiency significantly increased the migratory speed of CGE-derived INs and affected transcriptional programmes regulating neuronal migration. Postnatal studies revealed that SERT deficiency altered the cortical laminar distribution of subtypes of CGE-derived INs but not MGE-derived INs. More specifically, we found that the distribution of vasointestinal peptide (VIP)-expressing INs in layer 2/3 was abnormal in both genetic and pharmacological SERT-deficiency models. Collectively, these data indicate that early-life SERT deficiency has an impact on the migration and molecular programmes of CGE-derived INs, thus leading to specific alterations in the positioning of VIP-expressing INs. These data add to the growing evidence that early-life serotonin dysregulation affects cortical microcircuit formation and contributes to the emergence of psychiatric-relevant phenotypes.

Early life trauma (ELT) has been shown to impair affective control and attention well into adulthood. Neuroimaging studies have further shown that ELT was associated with decreased white matter integrity in the prefrontal areas in children and adults. However, no study to date has looked at the relationship between white matter integrity and affective control in individuals with and without a history of ELT. To examine this, we tested 240 Veterans with (ELT N = 80) and without (NoELT N = 160) a history of childhood sexual abuse, physical abuse or family violence. Affective control was measured with the Affective Go/No-Go (AGN) and attention was indexed with the Test of Variable Attention (TOVA). White matter integrity was measured using fractional anisotropy (FA). Results showed greater number of errors on the AGN in ELT compared to NoELT. There was no difference on the TOVA. While there were no mean differences in FA, there was an interaction between FA and reaction time to positive stimuli on the AGN where the ELT group showed a positive relationship between FA and reaction time in right frontal and prefrontal areas, whereas the NoELT group showed a negative or no association between FA and reaction time. This suggests that ELT may be associated with a distinct brain-behavior relationship that could be related to other determinants of FA than those present in healthy adults.

Food quality shapes life history traits either directly or through response of individuals to additional environmental factors, such as chemical cues. Plant extracts used as food additives modulate key life history traits; however little is known regarding such effects for olfactory chemical cues. Exploiting an interesting experimental system that involves the olive fly (Bactrocera oleae) and the plant metabolite α-pinene we asked whether exposure of adults to this compound modulates adult longevity and female reproduction in similar manner in a stressful – dietary (protein) restricted (DR) and in a relaxed- full diet (FD) feeding environment. Accordingly, we exposed males and females to the aroma of α-pinene and measured lifespan and age-specific fecundity in the above two dietary contexts. Our results demonstrate that exposure to α-pinene increased longevity in males and fecundity in females only under dietary restricted conditions. In relaxed food conditions, females exposed to α-pinene shifted high egg-laying towards younger ages compared to non-exposed ones. This is the first report demonstrating that a plant compound affects key life history traits of adult olive flies through olfaction. These effects are sex-specific and more pronounced in dietary restricted adults. Possible underlying mechanisms and the ecological significance are discussed. PMID:27339862

Background and objective COPD, a systemic illness associated with the impairment of different organs, affects patient prognosis and quality of life. The aim of this study was to evaluate the association between right ventricle (RV) function, the BODE (body mass index, airflow obstruction, dyspnea, and exercise capacity) index (a multifunctional scale for the assessment of mortality risk), and quality of life in patients with COPD. Methods A cross-sectional study was carried out in 107 outpatients presenting with stable COPD who underwent clinical assessment, spirometry, arterial blood gas analyses, a 6-minute walk test, electrocardiography, and echocardiogram and who responded to the Saint George’s Respiratory Questionnaire (SGRQ). Results Among the study subjects, 53% (57/107) were males, and the mean age was 65.26±8.81 years. A positive correlation was observed between RV dysfunction measured by the myocardial performance index using tissue Doppler (MPIt) and the BODE index, even after adjustment for age and partial pressure of oxygen (r2=0.47; P<0.01). Patients with alterations in the MPIt had worse quality of life, and a statistically significant difference was found for different domains of the SGRQ. Patients with a normal MPIt had a mean total score of 46.2±18.6, whereas for those with MPIt alterations, the mean total score was 61.6±14.2 (P=0.005). These patients had a 1.49-fold increased risk of exhibiting SGRQ total score above the upper limit of the 95% CI (P=0.01). Conclusion The findings of this study suggest that RV dysfunction as measured by the MPIt was associated with impairment in quality of life and a worse BODE index in COPD patients, irrespective of age and hypoxemia status.

Background. Our aim was to evaluate the real effect of dysautonomic symptoms on the influence of affective pain perception on quality of life in PD patients. Methods. An observational cross-sectional study was carried out using 105 Parkinson's disease (PD) patients of the Movement Disorders Unit, Hospital de Cruces (Bilbao, Spain) [men 59 (56.2%), women 46 (43.85%)]. Statistical analysis was made in order to evaluate the possible association of pain with life quality. Results. Quality of life measured by PDQ-39 (Parkinson's Disease Questionnaire for quality of life) was statistically associated with affective dimension of pain (PRIA, affective pain rating index). However, the influence of this dimension on PDQ-39 was different in the specific case of PD patients that experimented a high score (>12) in SCOPA-AUT (Scale for Outcomes in PD-Autonomic scale). Conclusions. These results confirm the effect of affective perception of pain in life quality of PD patients, indicating the critical role of autonomic symptoms in the modulation of the influence of pain on quality of life and showing the possible utility of dysautonomia as clinical prognostic indicator of quality of life in PD patients affected by pain.

Deficits in memory for everyday activities are common complaints among healthy and demented older adults. The medial temporal lobes and dorsolateral prefrontal cortex are both affected by aging and early-stage Alzheimer's disease, and are known to influence performance on laboratory memory tasks. We investigated whether the volume of these structures predicts everyday memory. Cognitively healthy older adults and older adults with mild Alzheimer's-type dementia watched movies of everyday activities and completed memory tests on the activities. Structural MRI was used to measure brain volume. Medial temporal but not prefrontal volume strongly predicted subsequent memory. Everyday memory depends on segmenting activity into discrete events during perception, and medial temporal volume partially accounted for the relationship between performance on the memory tests and performance on an event-segmentation task. The everyday-memory measures used in this study involve retrieval of episodic and semantic information as well as working memory updating. Thus, the current findings suggest that during perception, the medial temporal lobes support the construction of event representations that determine subsequent memory.

Exposure to stress during an insect’s larval development can have carry-over effects on adult life history traits and susceptibility to pathogens. We investigated the effects of larval nutritional stress for the first time using field mosquito vectors and malaria parasites. In contrast to previous studies, we show that larval nutritional stress may affect human to mosquito transmission antagonistically: nutritionally deprived larvae showed lower parasite prevalence for only one gametocyte carrier; they also had lower fecundity. However, they had greater survival rates that were even higher when infected. When combining these opposing effects into epidemiological models, we show that larval nutritional stress induced a decrease in malaria transmission at low mosquito densities and an increase in transmission at high mosquito densities, whereas transmission by mosquitoes from well-fed larvae was stable. Our work underscores the importance of including environmental stressors towards understanding host–parasite dynamics to improve disease transmission models and control. PMID:27827429

End of life care policy in the UK advocates open discussions between health professionals and patients as the end of life approaches. Despite well documented understanding of the progression of life-limiting neuromuscular diseases, the majority of patients affected by such conditions die without a formal end of life plan in place. We performed a systematic review to investigate conversations regarding end of life care between healthcare professionals and younger adult patients with life-limiting neuromuscular diseases. The search strategy included terms that focused on death and dying along with other factors that could impact length of life. The review found a very limited body of literature regarding end of life care conversations between young people affected by neuromuscular diseases and health professionals. The views and preferences of patients themselves have not been investigated. There is a shared reluctance of patients, family carers and healthcare professionals to initiate end of life care discussions. There are many factors that need to be investigated further in order to develop a consensus that would allow healthcare professionals to engage patients in end of life care conversations allowing them to face the end of their lives with appropriate plans in place.

Purpose Complaints from spinal cord injury (SCI) patients are typically related to physical disability affecting activities of daily life. However, difficulties with voiding and defecation and/or sexual function can also be major concerns. The general population and even physicians are generally unaware of these complaints; therefore, this study focuses on surveying SCI patients regarding challenges that are faced in daily life. Methods A questionnaire was administered randomly and anonymously to SCI patients who visited the Korea Spinal Cord Injury Association and several rehabilitation hospitals in the Republic of Korea in 2013. All participants gave their consent prior to filling out the questionnaire. Results A total of 299 patients answered the questionnaire; the male to female ratio was 5.8:1 and common vectors for injury were motor vehicle accidents, industrial accidents, and falling down. Of the 169 patients who answered the ‘most troublesome’ and ‘wish would improve’ complaints questionnaire properly, urinary problems were most common, specifically incontinence and urinary tract infection. Among all patients, 67% were using clean intermittent catheterization, 63% were taking voiding-related medications, 83% had sexual desires, and among the 122 patients who did not have offspring, 27% had future plans for children. Conclusions From this questionnaire, we discovered that SCI patients in the South Korea suffer not only from physical disability but also many other quality-of-life-related problems. When managing SCI patients, physicians should show greater concern and educate patients about problems related to voiding and sexual activity, rather than just physical disability. PMID:28043106

Breast milk is practically the only food ingested during the first months of life in fully breastfed infants and it is assumed to match the infant's nutritional needs. Epidemiological data suggest that breastfeeding compared with infant formula feeding confers protection against several chronic diseases later on in life and, particularly, against obesity and related medical complications. However, causality has not been related to any specific compound of breast milk. Recent data in our laboratory have identified leptin as the specific compound that is responsible for some of these beneficial effects of breastfeeding. The hormone leptin was identified as a key candidate because it is present in breast milk, but is not present in infant formula, and when ingested during the suckling period can be absorbed by the immature stomach exerting biological effects. Evidence of the beneficial effects of breast milk leptin was obtained from human studies, showing that milk-borne maternal leptin appeared to give moderate protection to infants from excess weight gain. Direct cause-effect evidence was obtained in rats, where oral leptin supplementation during the suckling period resulted in a decrease in food intake, affected food preferences in favour of carbohydrates versus fat, and protected against overweight in adulthood, with an improvement of related parameters such as leptin and insulin sensitivity. These findings open a new area of research on the use of leptin in the design of more appropriate infant formula, which is significant considering the increasing incidence of obesity and its associated medical complications.

The question of whether there is a connection between income and psychological well-being is a long-studied issue across the social, psychological, and behavioral sciences. Much research has found that richer people tend to be happier. However, relatively little attention has been paid to whether happier individuals perform better financially in the first place. This possibility of reverse causality is arguably understudied. Using data from a large US representative panel, we show that adolescents and young adults who report higher life satisfaction or positive affect grow up to earn significantly higher levels of income later in life. We focus on earnings approximately one decade after the person's well-being is measured; we exploit the availability of sibling clusters to introduce family fixed effects; we account for the human capacity to imagine later socioeconomic outcomes and to anticipate the resulting feelings in current well-being. The study's results are robust to the inclusion of controls such as education, intelligence quotient, physical health, height, self-esteem, and later happiness. We consider how psychological well-being may influence income. Sobel-Goodman mediation tests reveal direct and indirect effects that carry the influence from happiness to income. Significant mediating pathways include a higher probability of obtaining a college degree, getting hired and promoted, having higher degrees of optimism and extraversion, and less neuroticism.

We used a nationally representative panel of Australian households to replicate a study by Yap et al. (2012) that evaluated how life satisfaction changed following major life events and the extent to which personality moderated those changes. We replicated the protective function of marriage but found that long-term declines that follow widowhood mostly reflect normative changes. In addition, we found that people reported slight decreases in positive affect following marriage and childbirth, an increase in positive affect following widowhood, and a slight increase in negative affect following childbirth, relative to normative trajectories. The Big Five did not moderate response to life events in a way that is consistent with past theory and research. PMID:25419012

Early life stressors can affect aging and life expectancy in positive or negative ways. Individuals can adjust their behavior and molecular physiology based on early life experiences but relatively few studies have connected such mechanisms to demographic patterns in social organisms. Sociality buffers individuals from environmental influences and it is unclear how much early life stress affects later life history. Workers of the honey bee (Apis mellifera L.) were exposed to two stressors, Varroa parasitism and Paraquat exposure, early in life. Consequences were measured at the molecular, behavioral, and demographic level. While treatments did not significantly affect levels of oxidative damage, expression of select genes, and titers of the common deformed wing virus, most of these measures were affected by age. Some of the age effects, such as declining levels of deformed wing virus and oxidative damage, were opposite to our predictions but may be explained by demographic selection. Further analyses suggested some influences of worker behavior on mortality and indicated weak treatment effects on behavior. The latter effects were inconsistent among the two experiments. However, mortality rate was consistently reduced by Varroa mite stress during development. Thus, mortality was more responsive to early life stress than our other response variables. The lack of treatment effects on these measures may be due to the social organization of honey bees that buffers the individual from the impact of stressful developmental conditions.

Smoking is a causative factor in oral squamous cell carcinomas (SCC). Unfortunately, only poor data exist regarding the quality of life of smokers vs non-smokers with SCC. The purpose of this study is to show a correlation between variables for comprehensive interdisciplinary rehabilitation and better patient quality of life (LQ). A total collective of 1,761 patients from 38 hospitals within the German-language area of Germany, Austria and Switzerland (DÖSAK-REHAB-STUDIE) yielding 1,652 patients' questionnaires containing 147 items were evaluated. They refer to the periods before (t1) and immediately after surgery (t2), as well as at least 6 months later (t3). LQ was determined by the patient and ranges from 0% to 100%. Significant differences were found between smokers (80%) and non-smokers (20%) with respect to diagnosis, therapy and rehabilitation. Disabilities and impairments in speech, appearance, chewing/swallowing, pain and LQ were examined. Smokers were more often and more severely affected. Differences were found in the size of the tumour, scar tissue, ingestion, functionality of the facial muscles and a numb feeling in the head and shoulder area. Smoking has a severe effect on the oral cavity. Non-smokers suffer far less from the effects of SCC and the ensuing therapy. During therapy and rehabilitation, the LQ is much higher in non-smokers. This supports the importance of enhanced efforts to inform people about the consequences of smoking so as to prevent them from smoking. Moreover, psychological support might be helpful to give up smoking.

The aim of this study was to examine the neuropathic pain component of knee osteoarthritis (OA) patients and to investigate the relationship between neuropathic pain, disease stage, functional state, depression, anxiety, and quality of life. This study included 60 patients with knee OA. All demographic data and radiological results were recorded. Visual Analog Scale (VAS), Timed Up and Go Test, Chair Stand Test, Western Ontario and McMasters Universities Osteoarthritis Index (WOMAC), PainDETECT questionnaire, DN4 questionnaire, Short form-36 questionnaire, and Hospital Anxiety Depression Scale were performed for each patient. Neuropathic pain was detected in 66.7% of patients based on the PainDETECT scale and in 46.7% of patients based on DN4 scale. VAS-resting, OA grade, WOMAC scores, and SF-scores showed a significant difference in patients that detected neuropathic pain with PainDETECT (p<0.05). Based on the DN4 scale, patients with neuropathic pain had significantly higher WOMAC scores and significantly lower SF-36 scores (p<0.05). The PainDETECT questionnaire scores showed positive correlations with Timed Up-and-go Test, VAS-resting, WOMAC scores, Hospital Anxiety Depression Scale scores, and a negative correlation with all SF-36 scores (p<0.05). DN4 questionnaire scores showed a negative correlation with SF-36 scores and positive correlation with WOMAC scores (p<0.05). To conclude, it should be kept in mind that patients with knee OA who describe intense pain may have a neuropathic component involved in the clinical condition. Quality of life and functional capacity are adversely affected in patients with knee OA who have neuropathic pain. This should be taken into account while planning the treatment of these patients.

This research addresses whether one underlying concept of appreciation exists across different classes of objects. Three studies were done. To identify aesthetic properties relevant for the aesthetic judgment of everyday objects and paintings, in Study 1 expert interviews were conducted with 12 interior designers, object-oriented designers and architects, and 12 students of art history. In Study 2, multidimensional unfolding (MDU) was used to examine whether common judgment criteria can be identified for the objects of the different classes. A sample of 217 German subjects participated. 2- or 3-dimensional MDU solutions resulted for each object class. The identified dimensions were labeled using the aesthetic properties derived from the expert interviews (Study 1). These dimensions represent relevant dimensions of aesthetic judgment on which object properties vary. Study 2 suggested that people use different dimensions of aesthetic judgment for different object classes. The identified dimensions were then used to construct three sets of systematically varied everyday objects and one set of systematically varied paintings. Using this stimulus material in Study 3, conjoint analysis indicated these dimensions are differentially important for the overall aesthetic judgment.

force fed irrespective of their prospects of survival and suffering which this will cause them and their parents. Clinical decisions have been most seriously affected by recent developments in the law of negligence. 1 of the main reasons for this has been the unsatisfactory way in which the adversary system of law ldeals with expert evidence. Attempts have been made to provide courts of law in the UK an agreed statement on expert medical matters, there is a long way to go before reaching the position achieved in many civil law countries on the continent of Europe where the experts recognized by the court hammer out an agreed upon opinion through scientific discourse and without the restrictions of evidentiary rules which are aimed more at the establishment of facts than the validity of scientific opinion. Those who attack the medical profession as being paternalistic and authoritative in making clinical decisions involving life and death fail to realize that the easy way out for the medical profession is to treat every case, however hopeless, with the full technology available, disregarding the patient's and family's interests, the costs in resources, and ignoring the stark reality of the problem.

Much attention has been paid to the psychological processes underlying the improvement in mood states and human well-being, particularly during adolescence. Theoretical and empirical research suggests that emotional skills may play a role in enhancing perceived well-being; however, the mechanisms involved in during adolescence are unclear. The purpose of this study was to extend understanding by investigating the potential mediators of the relationship between emotional intelligence (EI) and life satisfaction in a 2-years study. Participants were 269 high school students (145 girls and 124 boys) who completed the self-report perceived emotional intelligence (PEI) Scale, the Satisfaction with Life Scale, and the Positive Affect and Negative Affect Scale three times at 1-year intervals. The three-step longitudinal design corroborated earlier research indicating that positive and negative affect mediate the relationships between EI and life satisfaction. Students with high PEI tended to have more positive experiences and fewer negative experiences, which contributed to their greater life satisfaction. No sex differences were found in the multi-group analyses, suggesting that the causal relationships are similar in both sexes. These findings extend our understanding of the complex network of relationships involving PEI and life satisfaction in adolescence. Implications and limitations of the findings are discussed.

It has been known for many years that multiple early life factors can adversely affect lung function and future respiratory health. This is the first systematic review to attempt to analyse all these factors simultaneously. We adhered to strict a priori criteria for inclusion and exclusion of studies. The initial search yielded 29,351 citations of which 208 articles were reviewed in full and 25 were included in the review. This included 6 birth cohorts and 19 longitudinal population studies. The 25 studies reported the effect of 74 childhood factors (on their own or in combinations with other factors) on subsequent lung function reported as percent predicted forced expiration in one second (FEV1). The childhood factors that were associated with a significant reduction in future FEV1 could be grouped as: early infection, bronchial hyper-reactivity (BHR) / airway lability, a diagnosis of asthma, wheeze, family history of atopy or asthma, respiratory symptoms and prematurity / low birth weight. A complete mathematical model will only be possible if the raw data from all previous studies is made available. This highlights the need for increased cooperation between researchers and the need for international consensus about the outcome measures for future longitudinal studies.

This study aimed at determining these factors--ventricular fibrillation (VF) in acute phase of myocardial infarction MI), thrombolytic therapy, beta-blockers after MI, cardiac rehabilitation--affect quality of life (QOL) during the follow-up. The study involved 100 patients (mean age 45.5 years), on the average 2 years after MI, MI has complicated VF in 50 patients. Questionnaire of QOL after MI developed internally, taking into account 26 features (clinical, emotional and social status), and estimating anxiety level (STAI) were used. Computer medical diagnostics "SyntMED" (Krefft's method) was used. In both groups after MI (complicated and not complicated VF) beneficial effect of: thrombolytic treatments in acute phase MI (0.65 vs conventional 0.45, p > 0.05), use of beta-blockers after MI (0.56 vs 0.41 p < 0.05), and cardiac rehabilitation (0.64 vs 0.44 p < 0.05) on value QOL were noted. Patients after MI complicated VF had higher level of anxiety. Patients who returned to work had higher index QOL (0.62 vs 0.39). Ventricular fibrillation complicated the acute phase of MI had no significant effect on follow-up QL.
In Sweden, during the last decade, the artist has come to function as a creative resource in workplaces. There are two organisations, Skiss (Contemporary Artist in the Contemporary Society) and Airis (Artist in Residence), that organise projects for artists and coworkers. These projects are intended to have a positive effect on the well-being of organisations and their employees through artistic means, and the artist often focuses on the social interaction between the employees in their work. The artists' work involves frequent interaction with coworkers. The aim of this article was to describe how visual artists' roles as artists are affected by their engagement in artistic and social projects at workplaces in Sweden. The focus in the article is on the social interaction between artists and employees. The study is a qualitative narrative interview study with fine artists participating in different projects in work life. Since the artist's intervention is usually directed towards social relations in the workplaces, a social perspective on well-being is from a micro-sociological point of view. The categories in the interviews were how the artists worked with the projects, how the social interaction between artists and coworkers worked out, and how the artists evaluated the projects in relation to their ambitions. The results show that, many times, the artistic projects promote well-being in organisations and to some extent benefit the artist, but that the ability of the artists to actually function as artists can be problematic.

Background Health-related quality of life (HRQOL) is increasingly measured as an outcome for clinical and health services research. However, relatively little is known about how non-health factors affect HRQOL. Personality is a potentially important factor, yet evidence regarding the effects of personality on HRQOL measures is unclear. Methods This systematic review examined the relationships among aspects of personality and HRQOL. Eligible studies were identified from Medline and PsycINFO. The review included 76 English-language studies with HRQOL as a primary outcome and that assessed personality from the psychological perspective. Individuals with various health states, including ill (e.g., cancer, cardiovascular disorders), aging, and healthy, were included in this review study. Results Some personality characteristics were consistently related to psychosocial aspects more often than physical aspects of HRQOL. Personality characteristics, especially neuroticism, mastery, optimism, and sense of coherence were most likely to be associated with psychosocial HRQOL. Personality explained varying proportions of variance in different domains of HRQOL. The range of variance explained in psychosocial HRQOL was 0 to 45% and the range of explained variance in physical HRQOL was 0 to 39%. Conclusions Personality characteristics are related to HRQOL. Systematic collection and analysis of personality data alongside HRQOL measures may be helpful in medical research, clinical practice, and health policy evaluation. PMID:28355244

Spatial cognition in vertebrates is adversely affected by a lack of environmental complexity during early life. However, to our knowledge, no previous studies have tested the effect of early exposure to varying degrees of environmental complexity on specific components of spatial cognition in chickens. There are two main rearing systems for laying hens in the EU: aviaries and cages. These two systems differ from one another in environmental complexity. The aim of the present study was to test the hypothesis that rearing in a barren cage environment relative to a complex aviary environment causes long-lasting deficits in the ability to perform spatial tasks. For this purpose, 24 white Dekalb laying hens, half of which had been reared in an aviary system and the other half in a conventional cage system, were tested in a holeboard task. Birds from both treatment groups learnt the task; however, the cage-reared hens required more time to locate rewards and had poorer levels of working memory. The latter finding supports the hypothesis that rearing in a barren environment causes long-term impairment of short-term memory in chickens. PMID:26664932

Environmental factors clearly influence the pathogenesis of Type 1 diabetes, an autoimmune disease. We have studied gut microbiota as important environmental agents that could affect the initiation or progression of type 1 diabetes especially in the prenatal period. We used neomycin, targeting mainly Gram negative or vancomycin, targeting mainly Gram positive bacteria, to treat pregnant NOD mothers and to study autoimmune diabetes development in their offspring. Neomycin-treated offspring were protected from diabetes, while vancomycin-treated offspring had accelerated diabetes development, and both antibiotics caused distinctly different shifts in gut microbiota composition compared with the offspring from untreated control mice. Our study demonstrated that neomycin treatment of pregnant mothers leads to generation of immune-tolerogenic antigen-presenting cells (APCs) in the offspring and these APCs had reduced specific autoantigen-presenting function both in vitro and in vivo. Moreover, the protection from diabetes mediated by tolerogenic APCs was vertically transmissible to the second generation. In contrast, more diabetogenic inflammatory T cells were found in the lymphoid organs of the offspring from the vancomycin-treated pregnant mothers. This change however was not transmitted to the second generation. Our results suggested that prenatal exposure to antibiotic influenced gut bacterial composition at the earliest time point in life and is critical for consequent education of the immune system. As different bacteria can induce different immune responses, understanding these differences and how to generate self-tolerogenic APCs could be important for developing new therapy for type 1 diabetes.
Background This study aims to (i) evaluate the association between anxiety and depressive symptoms and health-related quality of life (HRQoL); and (ii) identify the effect modifiers of this relationship in patients with chronic obstructive pulmonary disease (COPD). Methods A total of 337 clinically stable COPD patients answered the St. George's Respiratory Questionnaire (SGRQ) (assessing HRQoL) and the Hospital Anxiety and Depression Scale (HADS). Socio-demographic information, lung function, and other clinical data were collected. Results Most patients (93%) were male; they had a mean (SD) age of 68 (9) years and mild to very severe COPD (post-bronchodilator FEV1 52 (16)% predicted). Multivariate analyses showed that anxiety, depression, or both conditions were associated with poor HRQoL (for all SGRQ domains). The association between anxiety and total HRQoL score was 6.7 points higher (indicating a worse HRQoL) in current workers than in retired individuals. Estimates for patients with "both anxiety and depression" were 5.8 points lower in stage I-II than in stage III-IV COPD, and 10.2 points higher in patients with other comorbidities than in those with only COPD. Conclusions This study shows a significant association between anxiety, depression, or both conditions and impaired HRQoL. Clinically relevant factors affecting the magnitude of this association include work status, COPD severity, and the presence of comorbidities. PMID:20875100

The aim of this cross-sectional study was to identify subgroups of patients on the basis of their activity patterns and to investigate their relationship with life goals, optimism, affect, and functioning. The sample was comprised of 276 patients with chronic musculoskeletal pain. Hierarchical cluster analysis was performed on the activity pattern variables and the resulting clusters were compared using 1-way analysis of variance. The 4-cluster was the optimal solution. The 4 clusters comprised: 1) avoiders: patients with high levels of avoidance and low levels of persistence, who use pacing to reduce pain, 2) doers: patients with high levels of persistence and low levels of pacing and avoidance, 3) extreme cyclers: patients with high levels of avoidance and persistence and low levels of pacing, and 4) medium cyclers: patients with moderately high levels of avoidance and persistence and high levels of pacing. Comparison of the clusters showed that doers had the most adaptive profile, whereas avoiders, followed by extreme cyclers, had unhealthy profiles. Doers showed a high level of optimism and a good balance between goal value, expectancy, and conflict.

Does trait self-control (TSC) predict affective well-being and life satisfaction--positively, negatively, or not? We conducted three studies (Study 1: N = 414, 64% female, Mage = 35.0 years; Study 2: N = 208, 66% female, Mage = 25.24 years; Study 3: N = 234, 61% female, Mage = 34.53 years). The key predictor was TSC, with affective well-being and life satisfaction ratings as key outcomes. Potential explanatory constructs including goal conflict, goal balancing, and emotional distress also were investigated. TSC is positively related to affective well-being and life satisfaction, and managing goal conflict is a key as to why. All studies, moreover, showed that the effect of TSC on life satisfaction is at least partially mediated by affect. Study 1's correlational study established the effect. Study 2's experience sampling approach demonstrated that compared to those low in TSC, those high in TSC experience higher levels of momentary affect even as they experience desire, an effect partially mediated through experiencing lower conflict and emotional distress. Study 3 found evidence for the proposed mechanism--that TSC may boost well-being by helping people avoid frequent conflict and balance vice-virtue conflicts by favoring virtues. Self-control positively contributes to happiness through avoiding and dealing with motivational conflict.

This study quantifies the environmental impact of milk production of Italian Mediterranean buffaloes and points out the farm characteristics that mainly affect their environmental performance. Life cycle assessment was applied in a sample of 6 farms. The functional unit was 1 kg of normalized buffalo milk (LBN), with a reference milk fat and protein content of 8.3 and 4.73%, respectively. The system boundaries included the agricultural phase of the buffalo milk chain from cradle to farm gate. An economic criterion was adopted to allocate the impacts on milk production. Impact categories investigated were global warming (GW), abiotic depletion (AD), photochemical ozone formation (PO), acidification (AC), and eutrophication (EU). The contribution to the total results of the following farm activities were investigated: (1) on-farm energy consumption, (2) manure management, (3) manure application, (4) on-farm feed production (comprising production and application of chemical fertilizers and pesticides), (5) purchased feed production, (6) enteric fermentation, and (7) transport of purchased feeds, chemical fertilizers, and pesticides from producers to farms. Global warming associated with 1 kg of LBN resulted in 5.07 kg of CO₂ Eq [coefficient of variation (CV)=21.9%], AD was 3.5 × 10(-3) kg of Sb Eq (CV=51.7%), PO was 6.8 × 10(-4) kg of C₂H₄ Eq (CV=28.8%), AC was 6.5 × 10(-2) kg of SO₂ Eq (CV=30.3%), and EU was 3.3 × 10(-2) kg of PO₄(3-) Eq (CV=36.5%). The contribution of enteric fermentation and manure application to GW is 37 and 20%, respectively; on-farm consumption, on-farm feed production, and purchased feed production are the main contributors to AD; about 70% of PO is due to enteric fermentation; manure management and manure application are responsible for 55 and 25% of AC and 25 and 55% of EU, respectively. Methane and N₂O are responsible for 44 and 43% of GW, respectively. Crude oil consumption is responsible for about 72% of AD; contribution of

The apolipoprotein E (ApOE) ε4 allele is associated with neuropathological buildup of amyloid in the brain, and with lower performance on some laboratory measures of memory in some populations. In two studies, we tested whether ApOE genotype affects memory for everyday activities. In Study 1, participants aged 20-79 years old (n = 188) watched movies of actors engaged in daily activities and completed memory tests for the activities in the movies. In Study 2, cognitively healthy and demented older adults (n = 97) watched and remembered similar movies, and also underwent structural MRI scanning. All participants provided saliva samples for genetic analysis. In both samples we found that, in older adults, ApOE ε4 carriers demonstrated worse everyday memory performance than did ε4 noncarriers. In Study 2, ApOE ε4 carriers had smaller medial temporal lobes (MTL) volumes, and MTL volume mediated the relationship between ApOE genotype and everyday memory performance. These everyday memory tasks measure genetically determined cognitive decline that can occur prior to a clinical diagnosis of dementia. Further, these tasks are easily administered and may be a useful clinical tool in identifying ε4 carriers who may be at risk for MTL atrophy and further cognitive decline that is a common characteristic of the earliest stages of Alzheimer's disease.

Exposure to traumatic events is common in children and adolescent. Post traumatic stress disorder (PTSD) is an emotional reaction to traumatic events, which is increasingly recognized to be a prevalent and disabling disorder. The aim of this study is to determine the distribution of normative life events which predicts PTSD in youth who referred to an outpatient clinic in Rasht, Iran. This study is a cross-sectional descriptive study. The samples of children and adolescents ranging from 1-18 yr old who were diagnosed PTSD based on DSM-IV criteria in psychiatric interview and K-SADS (Kiddie-schedule for affective disorder and schizophrenia for school age children) semi-structured diagnostic interview, from 2005 until 2008.The information consist of: age, sex, comorbidity with PTSD, events accompanying with PTSD, and time interval between events and visit. Eighty four youth who met the diagnosis of PTSD and their parents participated in the survey. Half of PTSD youth were 6-11 years old and admitted to clinic in the first 3 months after events. The most common events were witnessing violent or fearful scenes on TV followed by witnessing someone's death or funeral ceremony. The most comorbidity with PTSD included: attention deficit hyperactivity disorder, depression and anxiety. Our results indicate that youth exposure to violent or fearful scenes on TV could be very traumatic for them. Informing parents about the potential effect of low-magnitude stressors such as violent or fearful scenes on TV and funeral ceremony can decrease the prevalence of PTSD in youth.

Indigenous species are less commonly used in laboratory aquatic toxicity tests compared with standard test species due to (1) limited availability lack of requisite information necessary for their acclimation and maintenance under laboratory conditions and (2) lack of information on their sensitivity and the reproducibility of toxicity test results. As part of the Natural Resource Damage Assessment aquatic toxicity program in response to the Deepwater Horizon Oil incident (2010), sensitive life stages of native Gulf of Mexico species were evaluated in laboratory toxicity tests to determine the potential effects of the spill. Fish (n = 5) and invertebrates (n = 2) selected for this program include the following: the Florida pompano (Trachinotus carolinus), red drum (Sciaenops ocellatus), spotted sea trout (Cynoscion nebulosus), cobia (Rachycentron canadum), red porgy (Pagrus pagrus), blue crab (Callinectes sapidus), and the common moon jellyfish (Aurelia aurita). Initially in the program, to establish part of the background information, acute tests with reference toxicants (CdCl2, KCl, CuSO4) were performed with each species to establish data on intraspecies variability and test precision as well as identify other factors that may affect toxicity results. Median lethal concentration (LC50) values were calculated for each acute toxicity test with average LC50 values ranging from 248 to 862 mg/L for fish exposures to potassium chloride. Variability between test results was determined for each species by calculating the coefficient of variation (%CV) based on LC50 values. CVs ranged from 11.2 % for pompano (96-h LC50 value) to 74.8 % for red porgy 24-h tests. Cadmium chloride acute toxicity tests with the jellyfish A. aurita had the lowest overall CV of 3.6 %. By understanding acute toxicity to these native organisms from a compound with known toxicity ranges and the variability in test results, acute tests with nonstandard species can be better interpreted and used

Background: Multiple sclerosis (MS) presents with many debilitating symptoms, including urinary incontinence (UI), that physical therapy (PT) may address; UI is widely prevalent, but PT management of symptoms lacks consensus. A meta-analysis of long-term nonsurgical and nonpharmaceutical treatment options may supply this deficiency. We analyzed the current evidence for effectiveness of PT to decrease UI and improve quality of life (QOL) in people with MS. Methods: An electronic search conducted through November 26, 2013, included the following search terms: incontinence, bladder dysfunction, urinary incontinence, multiple sclerosis, MS, physical therapy, physiotherapy, therapy, and rehabilitation. Criteria for inclusion were as follows: MS diagnosis, intervention involved PT for UI or bladder dysfunction, outcomes assessed QOL or UI, and at least a 4 of 10 on the Physiotherapy Evidence Database scale or a 2b level of evidence. Outcomes were combined across studies, and effect sizes are depicted in forest plots. Results: Six studies met the inclusion criteria. Between-group analysis revealed statistically significant differences in incontinence episodes and QOL, but did not reach significance for functional control mechanisms (eg, electromyography data on strength of contraction, relaxation, and endurance). Incontinence leakage episodes and QOL participation improved within groups. Conclusions: Meta-analysis indicates support for PT for minimizing incontinence compared with pretreatment and affecting incontinence and QOL more than control in people with MS. Protocols were heterogeneous regarding duration and type of PT intervention and were applied in different types of MS. Further research may reveal the most effective combination and variety of PT interventions for people with MS. PMID:26300703

Toward a space-time scale framework for the study of everyday life activity's adaptation to hazardous hydro-meteorological conditions: Learning from the June 15th, 2010 flash flood event in Draguignan (France)
Ruin, Isabelle; Boudevillain, Brice; Creutin, Jean-Dominique; Lutoff, Céline
Western Mediterranean regions are favorable locations for heavy precipitating events. In recent years, many of them resulted in destructive flash floods with extended damage and loss of life: Nîmes 1988, Vaison-la-Romaine 1992, Aude 1999 and Gard 2002 and 2005. Because of the suddenness in the rise of water levels and the limited forecasting predictability, flash floods often surprise people in the midst of their daily activity and force them to react in a very limited amount of time. In such fast evolving events impacts depend not just on such compositional variables as the magnitude of the flood event and the vulnerability of those affected, but also on such contextual factors as its location and timing (night, rush hours, working hours...). Those contextual factors can alter the scale and social distribution of impacts and vulnerability to them. In the case of flooding fatalities, for instance, the elderly are often said to be the most vulnerable, but when fatalities are mapped against basin size and response time, it has been shown that in fact it is young adults who are most likely to be killed in flash flooding of small catchments, whereas the elderly are the most frequent victim of large scale fluvial flooding. Further investigations in the Gard region have shown that such tendency could be explained by a difference of attitude across ages with respect to mobility related to daily life routine and constraints. According to a survey of intentional behavior professionals appear to be less prone to adapting their daily activities and mobility to rapidly changing environmental conditions than non-professionals. Nevertheless, even if this appears as a tendency in both the analysis of limited data on death circumstances and intended behavior surveys, behavioral verification is very much needed. Understanding how many and why people decide to travel in hazardous weather conditions and how they adapt (or not) their activities and schedule in response to

Life history consequences of stress in early life are varied and known to have lasting impacts on the fitness of an organism. Gene-environment interactions play a large role in how phenotypic differences are mediated by stressful conditions during development. Here we use natural allelic 'rover/sitter' variants of the foraging (for) gene and chronic early life nutrient deprivation to investigate gene-environment interactions on excretion phenotypes. Excretion assay analysis and a fully factorial nutritional regimen encompassing the larval and adult life cycle of Drosophila melanogaster were used to assess the effects of larval and adult nutritional stress on adult excretion phenotypes. Natural allelic variants of for exhibited differences in the number of fecal spots when they were nutritionally deprived as larvae and well fed as adults. for mediates the excretion response to chronic early-life nutritional stress in mated female, virgin female, and male rovers and sitters. Transgenic manipulations of for in a sitter genetic background under larval but not adult food deprivation increases the number of fecal spots. Our study shows that food deprivation early in life affects adult excretion phenotypes and these excretion differences are mediated by for.

Accessible surfaces of the most likely astrobiological habitats (Mars, Europa, Titan) in the solar system beyond Earth are exposed to various chemical and hydrologic weathering processes directly or indirectly induced by interaction with the overlying space environment. These processes can be both beneficial, through provision of chemical compounds and energy, and destructive, through chemical dissociation or burial, to detectable presence of biosignatures. Orbital, suborbital, and surface platforms carrying astrobiological instrumentation must survive, and preferably exploit, space environment interactions to reach these habitats and search for evidence of life or its precursors. Experience from Mars suggests that any detection of biosignatures must be accompanied by characterization of the local chemical environment and energy sources including irradiation by solar ultraviolet photons and energetic particles from the space environment. Orbital and suborbital surveys of surface chemistry and astrobiological potential in the context of the space environment should precede targeted in-situ measurements to maximize probability of biosignature detection through site selection. The Space Physics of Life (SPOL) investigation has recently been proposed to the NASA Astrobiology Institute and is briefly described in this presentation. SPOL is the astrobiologically relevant study of the interactions and relationships of potentially? or previously inhabited, bodies of the solar system with the surrounding environments. This requires an interdisciplinary effort in space physics, planetary science, and radiation biology. The proposed investigation addresses the search for habitable environments, chemical resources to support life, and techniques for detection of organic and inorganic signs of life in the context of the space environment.

This article examines the proposition that dietary protein in pre- and early postnatal life influences the development of adiposity in later life. In rodents, low protein intake during gestation can result in low birth weight and subsequently leads to various metabolic disturbances in adulthood, such as high blood pressure, impaired glucose tolerance and insulin resistance. The few controlled studies conducted in animals suggest that high protein or energy intake during gestation leads to low birth weights. Observational studies in humans have been inconclusive in establishing a relationship between dietary protein intake in pregnancy and effects on birth weight and adiposity of the offspring later in life. There is only weak epidemiological evidence linking high protein intake during early childhood and the development of obesity. By contrast, studies in domestic animals have found that higher levels of protein intake are often associated with lower rates of fat accretion. Additional studies are proposed to explore claims linking protein nutrition in early life to the postnatal development of obesity and disease in humans.

Aging and reduced longevity are due in part to the action of free radicals (FR). Melatonin (Mel) and thioctic acid (TA) are effective in protecting against the damage caused by FR. In this study, the effect of Mel and TA on the life cycle of Drosophila melanogaster was determined. We used a control group of flies, another group that was provided with Mel (0.43 mM) throughout their life cycle (Mel-c), a third group received Mel upon reaching adulthood (Mel-a) and two groups were fed with TA (2.15 mM) in the same manner (TA-c and TA-a). The number of eclosed, survival, phenotype changes, motor activity and the content of malondialdehyde (MDA) was evaluated in each group. Mel-c increased the eclosion rate and the motor activity of the flies. Mel-c and Mel-a increased the life span and decreased the concentrations of MDA. By contrast, TA-c diminished the eclosion rate, produced phenotypic changes and increased MDA levels and motor activity of the flies. TA-a extended the life span of flies, and did not alter MDA levels and motor activity when compared with the control group. In conclusion, Mel mitigated the effects caused by FR generated during aging, while TA-c increased lipid peroxidation and altered the phenotype of flies.

Body image (BI) can be described as the assessment of both positive and negative emotion for one’s own body parts and their characteristics by himself or herself. Current research has concentrated mostly on the status of negative BI as a risk factor for mental health problems rather than as a public health problem, thereby little is known about the effects of BI on quality of life. Thus, the purpose of this study was to assess the BI and Quality of Life (QoL) of individuals and to investigate the relationship between the two. Individuals over 15 living in Isparta city center constitute the universe of this cross-sectional analytical study, carried out in 2014. The BI of individuals was measured by the Body Image Scale and The QoL of individuals was measured using the World Health Organization (WHO) Quality of Life Scale Short Form. The mean age of the participants was 31.9 ± 13.0 and 56.0% were female, 36.8% were married and 81.7% had education above high school. 25.7% had at least one chronic disease and 17.7% received medication regularly. Having good-very good health perception, having higher income than expenses, making regular exercises were predictors in enhancing the quality of life in certain aspects, however having a good body image came out as a predictor enhancing the quality of life in all sub-domains. BI was found closely related with QoL in all sub-domains. Our findings suggest that greater attention should be to be given to BI as a strong predictor of QoL. PMID:27649389

The physical and mental needs of patients with coronary heart disease are affected by both the disease and the heart surgery in different ways. Such diverse needs require different approaches. A continuous care model, which involves orientation, sensitization, control, and evaluation, may favorably influence patient outcomes following coronary artery bypass grafting (CABG). We were interested to ascertain whether a continuous care model might lead to improved quality of life, compared with a routine care model, in patients undergoing CABG. A total of 66 patients scheduled for CABG were identified and randomized to receive either continuous care (based on the continuous care model) or routine postoperative management for 2 months. The subjects' quality of life and its physical and mental dimensions were measured by the 12-item Short-Form Health Survey. Each dimension was scored between 0 and 100, and higher scores indicated better quality of life. One and 2 months after the intervention, the scores of quality of life and its two dimensions were significantly higher in the intervention group than in the control group (P < .001). The application of the continuous care model can promote health-related quality of life in patients after CABG.

Successful conservation management requires an understanding of how species respond to intervention. Native and exotic species may respond differently to management interventions due to differences arising directly from their origin (i.e., provenance) or indirectly due to biased representations of different life history types (e.g., annual vs. perennial life span) or phylogenetic lineages among provenance (i.e., native or exotic origin) groups. Thus, selection of a successful management regime requires knowledge of the life history and provenance-bias in the local flora and an understanding of the interplay between species characteristics across existing environmental gradients in the landscape. Here we tested whether provenance, phylogeny, and life span interact to determine species distributions along natural gradients of soil chemistry (e.g., soil nitrogen and phosphorus) in 10 upland prairie sites along a 600-km latitudinal transect running from southern Vancouver Island in British Columbia, Canada, to the Willamette Valley in Oregon, USA. We found that soil nitrate, phosphorus, and pH exerted strong control over community composition. However, species distributions along environmental gradients were unrelated to provenance, life span, or phylogenetic groupings. We then used a greenhouse experiment to more precisely measure the response of common grass species to nitrogen and phosphorus supply. As with the field data, species responses to nutrient additions did not vary as a function of provenance, life span, or phylogeny. Native and exotic species differed strongly in the relationship between greenhouse-measured tolerance of low nutrients and field abundance. Native species with the greatest ability to maintain biomass production at low nutrient supply rates were most abundant in field surveys, as predicted by resource competition theory. In contrast, there was no relationship between exotic-species biomass at low nutrient levels and field abundance. The

Moodle is the one of most popular learning management systems. Situation in Liepaja University shows that Moodle is used mainly for content delivery. To activate student learning in Moodle and enhance Moodle usage, collaboration supported tools will be present for academic staff. Research is made to choose the most popular tools from the student point of view to enhance their learning. Focus group interviews is conducted to find out what web 2.0 collaboration tools students are using in their everyday life and what tools using in Moodle. The idea is to transmit the students' everyday life skills with Web 2.0 in the learning activities.

Determining the relationship between individual life-history traits and population dynamics is an essential step to understand and predict natural selection. Model organisms that can be conveniently studied experimentally at both levels are invaluable to test the rich body of theoretical literature in this area. The nematode Caenorhabditis elegans, despite being a well-established workhorse in genetics, has only recently received attention from ecologists and evolutionary biologists, especially with respect to its association with pathogenic bacteria. In order to start filling the gap between the two areas, we conducted a series of experiments aiming at measuring life-history traits as well as population growth of C. elegans in response to three different bacterial strains: Escherichia coli OP50, Salmonella enterica Typhimurium, and Pseudomonas aeruginosa PAO1. Whereas previous studies had established that the latter two reduced the survival of nematodes feeding on them compared to E. coli OP50, we report for the first time an enhancement in reproductive success and population growth for worms feeding on S. enterica Typhimurium. Furthermore, we used an age-specific population dynamic model, parameterized using individual life-history assays, to successfully predict the growth of populations over three generations. This study paves the way for more detailed and quantitative experimental investigation of the ecology and evolution of C. elegans and the bacteria it interacts with, which could improve our understanding of the fate of opportunistic pathogens in the environment.

Early-life social experiences cause lasting changes in behavior and health for a variety of animals including humans, but it is not well understood how social information ‘‘gets under the skin’’ resulting in these effects. Adult honey bees (Apis mellifera) exhibit socially coordinated collective nest defense, providing a model for social modulation of aggressive behavior. Here we report for the first time that a honey bee’s early-life social environment has lasting effects on individual aggression: bees that experienced high-aggression environments during pre-adult stages showed increased aggression when they reached adulthood relative to siblings that experienced low-aggression environments, even though all bees were kept in a common environment during adulthood. Unlike other animals including humans however, high-aggression honey bees were more, rather than less, resilient to immune challenge, assessed as neonicotinoid pesticide susceptibility. Moreover, aggression was negatively correlated with ectoparasitic mite presence. In honey bees, early-life social experience has broad effects, but increased aggression is decoupled from negative health outcomes. Because honey bees and humans share aspects of their physiological response to aggressive social encounters, our findings represent a step towards identifying ways to improve individual resiliency. Pre-adult social experience may be crucial to the health of the ecologically threatened honey bee. PMID:26493190

NRC regulations and industry standards provide flexibility to the nuclear industry for demonstrating cable design life goals. Allowable methods for qualifying in-containment cables include laboratory type testing, reference to operating experience, analysis, and combinations of the above. In practice most utilities have used laboratory type testing as the primary method for demonstrating cable life assurance. These tests are frequently performed prior to initial plant operation and include a laboratory accelerated test (lasting a few weeks to a few months) to demonstrate that a cable will function during accident conditions that might occur anytime during a 40-year plant life. Type test rigor and documentation depend strongly on specific utility commitments to satisfy various vintages of standards and implementing regulations. For plant operation beyond 40 years, demonstration of continued cable qualification will be necessary. This might be accomplished by reanalysis of the original qualification basis, by supplementing the original qualification basis with additional laboratory test data, by supplementing the original qualification basis with operational experience, by a combination of the above techniques, or by a cable replacement program. 22 refs., 1 tab.

Objective This study aimed to increase our understanding of general self-management (SM) abilities in COPD by determining if SM can predict disease specific quality of life (QoL), by investigating whether specific SM domains are significant in COPD and by exploring the mediating effect of the positive/negative affect in the association between SM and QoL. Methods Cross-sectional study based on 292 patients with COPD. Measures included demographics, lung function, gait speed, health care utilization, positive/negative affect, SM abilities, breathlessness and disease specific QoL. We performed, correlation, multiple regression models and mediation analysis (positive/negative affect being mediator between SM and QoL association). Results After controlling for breathlessness, living alone, marital status, hospitalization history, age and lung function, SM related to QoL (p< 0.0001). Investment in behaviors (hobbies and social relationships) and self-efficacy are SM domains independently related to QoL in COPD. Positivity measured by the positive/negative affect ratio completely mediates the relationship of SM with QoL. Conclusion SM is independently associated with disease specific QoL in COPD after adjustment significant covariates but positive/negative affect ratio completely mediates the relationship of SM with QoL. Practice implications Measuring positive/negative affect and addressing investment behavior and self-efficacy are important in implementing COPD-SM programs. PMID:26632024

Diet greatly influences gene expression and physiology. In mammals, elucidating the effects and mechanisms of individual nutrients is challenging due to the complexity of both the animal and its diet. Here, we used an interspecies systems biology approach with Caenorhabditis elegans and two of its bacterial diets, Escherichia coli and Comamonas aquatica, to identify metabolites that affect the animal's gene expression and physiology. We identify vitamin B12 as the major dilutable metabolite provided by Comamonas aq. that regulates gene expression, accelerates development, and reduces fertility but does not affect lifespan. We find that vitamin B12 has a dual role in the animal: it affects development and fertility via the methionine/S-Adenosylmethionine (SAM) cycle and breaks down the short-chain fatty acid propionic acid, preventing its toxic buildup. Our interspecies systems biology approach provides a paradigm for understanding complex interactions between diet and physiology.

The UK Food Standards Agency (FSA) convened a group of expert scientists to discuss and review UK FSA- and Department of Health-funded research on diet and bone health. This research focused on the lifestyle factors that are amenable to change and may significantly affect bone health and the risk of osteoporotic fracture. The potential benefits of fruits and vegetables, meat, Ca, vitamins D and K and phyto-oestrogens were presented and discussed. Other lifestyle factors were also discussed, particularly the effect of physical activity and possible gene-nutrient interactions affecting bone health.

Severe feather pecking (SFP) in commercial laying hens is a maladaptive behavior which is associated with anxiety traits. Many experimental studies have shown that stress in the parents can affect anxiety in the offspring, but until now these effects have been neglected in addressing the problem of SFP in commercially kept laying hens. We therefore studied whether parental stock (PS) affected the development of SFP and anxiety in their offspring. We used flocks from a brown and white genetic hybrid because genetic background can affect SFP and anxiety. As SFP can also be influenced by housing conditions on the rearing farm, we included effects of housing system and litter availability in the analysis. Forty-seven rearing flocks, originating from ten PS flocks were followed. Behavioral and physiological parameters related to anxiety and SFP were studied in the PS at 40 weeks of age and in the rearing flocks at one, five, ten and fifteen weeks of age. We found that PS had an effect on SFP at one week of age and on anxiety at one and five weeks of age. In the white hybrid, but not in the brown hybrid, high levels of maternal corticosterone, maternal feather damage and maternal whole-blood serotonin levels showed positive relations with offsprings' SFP at one week and offsprings' anxiety at one and five weeks of age. Disruption and limitation of litter supply at an early age on the rearing farms increased SFP, feather damage and fearfulness. These effects were most prominent in the brown hybrid. It appeared that hens from a brown hybrid are more affected by environmental conditions, while hens from a white hybrid were more strongly affected by parental effects. These results are important for designing measures to prevent the development of SFP, which may require a different approach in brown and white flocks.

The utility of antigen-binding antibody fragments is often limited by their short half-lives. Half-life extension of such fragments is usually accomplished by attachment or binding to high-molecular-weight carriers that reduce the renal elimination rate. However, the higher hydrodynamic radius results in greater confinement in the vascular compartment and, thus, lower tissue distribution. We have developed a chemically controlled drug delivery system in which the drug is covalently attached to hydrogel microspheres by a self-cleaving β-eliminative linker; upon subcutaneous injection, the t1/2,β of the released drug acquires the t1/2 of linker cleavage. In the present work, we compared the pharmacokinetics of an anti-TNFα scFv, the same scFv attached to 40 kDa PEG by a stable linker, and the scFv attached to hydrogel microspheres by a self-cleaving linker. We also developed a general approach for the selective attachment of β-eliminative linkers to the N-termini of proteins. In rats, the scFv had a t1/2,β of 4 h and a high volume of distribution at steady state (Vd,SS), suggesting extensive tissue distribution. The PEG-scFv conjugate had an increased t1/2,β of about 2 days but showed a reduced Vd,SS that was similar to the plasma volume. In contrast, the tissue-penetrable scFv released from the hydrogel system had a t1/2,β of about 2 weeks. Thus, the cleavable microsphere-scFv conjugate releases its protein cargo with a prolonged half-life comparable to that of most full-length mAbs and in a form that has the high tissue distribution characteristic of smaller mAb fragments. Other antigen-binding antibody fragments should be amenable to the half-life extension approach described here.

Stimulation of Type II taste receptor cells (TRCs) with T1R taste receptors causes sweet or umami taste, whereas T2Rs elicit bitter taste. Type II TRCs contain the calcium channel, calcium homeostasis modulator protein 1 (CALHM1), which releases adenosine triphosphate (ATP) transmitter to taste fibers. We have previously demonstrated with chorda tympani nerve recordings and two-bottle preference (TBP) tests that mice with genetically deleted Calhm1 (knockout [KO]) have severely impaired perception of sweet, bitter, and umami compounds, whereas their sour and salty tasting ability is unaltered. Here, we present data from KO mice of effects on glossopharyngeal (NG) nerve responses, TBP, food intake, body weight, and life span. KO mice have no NG response to sweet and a suppressed response to bitter compared with control (wild-type [WT]) mice. KO mice showed some NG response to umami, suggesting that umami taste involves both CALHM1- and non-CALHM1-modulated signals. NG responses to sour and salty were not significantly different between KO and WT mice. Behavioral data conformed in general with the NG data. Adult KO mice consumed less food, weighed significantly less, and lived almost a year longer than WT mice. Taken together, these data demonstrate that sweet taste majorly influences food intake, body weight, and life span.

Hypertension originates from early-life insults by so-called “developmental origins of health and disease” (DOHaD). Studies performed in the previous few decades indicate that fructose consumption is associated with an increase in hypertension rate. It is emerging field that tends to unfold the nutrient–gene interactions of maternal high-fructose (HF) intake on the offspring which links renal programming to programmed hypertension. Reprogramming interventions counteract disturbed nutrient–gene interactions induced by maternal HF intake and exert protective effects against developmentally programmed hypertension. Here, we review the key themes on the effect of maternal HF consumption on renal transcriptome changes and programmed hypertension. We have particularly focused on the following areas: metabolic effects of fructose on hypertension and kidney disease; effects of maternal HF consumption on hypertension development in adult offspring; effects of maternal HF consumption on renal transcriptome changes; and application of reprogramming interventions to prevent maternal HF consumption-induced programmed hypertension in animal models. Provision of personalized nutrition is still a faraway goal. Therefore, there is an urgent need to understand early-life nutrient–gene interactions and to develop effective reprogramming strategies for treating hypertension and other HF consumption-related diseases.

Heart transplantation has become an accepted therapy for patients suffering from terminal heart disease for whom neither standard forms of medication nor the usual surgery are of any benefit. Although results regarding postoperative quantity and quality of life are encouraging, it must not be overlooked that the patient and his family face, and have to overcome, profound psychosocial problems. The main stressors were identified in interviews with 47 heart transplant patients. The main preoperative problems were: the way of being informed about the diagnosis, the waiting period for transplantation, anguishing doubts about the decision to have a transplant, being a body without heart ('zombie'), guilt and shame regarding the donor, the reactions of others. Postoperatively the patients have to cope with: re-entering social systems, reactions of friends, neighbours and colleagues, rejection episodes, death of a fellow patient, the need to redesign family life. All the problems reported by the patients interviewed are discussed regarding their psychosocial implications, and hints are given on how to minimize them.

A small amount of research has examined the association between the belief in free will and subjective well-being (SWB) among Western laypersons from individualist cultures. However, no study has examined this association among participants from collectivist cultures (e.g., Eastern Asian cultures). Therefore, in this study, we explored this association among two large, independent cohorts of Chinese adolescents (N1 = 1,660; N2 = 639; high school students). The belief in free will was measured by a self-reported questionnaire (Cohorts 1 and 2) and a two-alternative forced choice question regarding the existence of free will (Cohort 2). SWB included cognitive well-being (life satisfaction) and affective well-being (positive and negative affect) in both cohorts. Data analyses indicated that a stronger belief in free will was consistently associated with higher life satisfaction and positive affect in both cohorts. Our investigation provides evidence supporting the cultural generality of the positive effects of believing in free will on SWB. PMID:28101072

Does money buy happiness, or does happiness come indirectly from the higher rank in society that money brings? We tested a rank-income hypothesis, according to which people gain utility from the ranked position of their income within a comparison group. The rank hypothesis contrasts with traditional reference-income hypotheses, which suggest that utility from income depends on comparison to a social reference-group norm. We found that the ranked position of an individual's income predicts general life satisfaction, whereas absolute income and reference income have no effect. Furthermore, individuals weight upward comparisons more heavily than downward comparisons. According to the rank hypothesis, income and utility are not directly linked: Increasing an individual's income will increase his or her utility only if ranked position also increases and will necessarily reduce the utility of others who will lose rank.

Following the 1980 US Supreme Court decision to allow a patent on a living organism, debate has continued on the moral issues involved in biotechnology patents of many kinds and remains a contentious issue for those opposed to the use of biotechnology in industry and agriculture. Attitudes to patenting in the life sciences, including those of the research scientists themselves, are analysed. The relevance of morality to patent law is discussed here in an international context with particular reference to the law of the European Patent Convention administered by the European Patent Office (EPO). The EPO has been the principal forum for opposition to such patents and the few cases under dispute in the EPO are reviewed, including patents for the onco-mouse, human relaxin gene, and the PGS herbicidally resistant plant (gmo). Morality provisions in the European Parliament and Council Directive 98/44/EC are also summarised.

Children born preterm often exhibit reduced lung function and increased severity of response to respiratory viruses, suggesting that premature birth has compromised proper development of the respiratory epithelium and innate immune defenses. Increasing evidence suggests that premature birth promotes aberrant lung development likely due to the neonatal oxygen transition occurring before pulmonary development has matured. Given that preterm infants are born at a point of time where their immune system is also still developing, early life oxygen exposure may also be disrupting proper development of innate immunity. Here, we review current literature in hopes of stimulating research that enhances understanding of how the oxygen environment at birth influences lung development and host defense. This knowledge may help identify those children at risk for disease and ideally culminate in the development of novel therapies that improve their health. PMID:26322310

Long-term survival after esophagectomy is improving, and hence, quality of life (QOL) of these patients has become a priority. There has been extensive debate regarding the optimal site of surgical anastomosis (cervical or intrathoracic). We aimed to evaluate the impact of anastomotic site on long-term QOL postesophagectomy. Quality of life questionnaires (European Organisation for Research and Treatment of Cancer [EORTC] C-30 and OG-25) were sent to patients surviving over 3 years following esophagectomy. The data were analyzed by site of esophagogastric anastomosis: intrathoracic or cervical. EORTC C-30 data were compared against the reference population data. Of the patients, 62 responded (82%) with a median time postsurgery of 6.1 years (range 3-12 years). Patient demographics were comparable. There was no significant difference between cervical or intrathoracic anastomosis groups for functional or symptom scores, focusing on dysphagia (cervical = 8.8 vs. intrathoracic = 17.6, P = 0.24), odynophagia (cervical = 13.4 vs. intrathoracic = 16.1, P = 0.68) and swallowing problems (cervical = 8.1 vs. intrathoracic = 13.4, P = 0.32). There was no difference in overall health score between groups (cervical = 70.5 vs. intrathoracic = 71.6, P = 0.46). Overall general health score was comparable with the reference population (esophagectomy group P = 70.9 ± 22.1 vs. reference population = 71.2 ± 22.4, P = 0.93). There is no difference in long-term QOL after esophagectomy between patients with a cervical or intrathoracic anastomosis. Scores compare favorably with EORTC reference data. Survival after esophagectomy is associated with recovery of QOL in the long term, regardless of site of anastomosis and despite worse gastrointestinal-related symptoms.

The pathogenesis of anxiety disorders is considered to be multifactorial with a complex interaction of genetic factors and individual environmental factors. Therefore, the aim of this study was to examine gene-by-environment interactions of the genes coding for catechol-O-methyltransferase (COMT) and monoamine oxidase A (MAOA) with life events on measures related to anxiety. A sample of healthy subjects (N = 782; thereof 531 women; mean age M = 24.79, SD = 6.02) was genotyped for COMT rs4680 and MAOA-uVNTR (upstream variable number of tandem repeats), and was assessed for childhood adversities [Childhood Trauma Questionnaire (CTQ)], anxiety sensitivity [Anxiety Sensitivity Index (ASI)] and anxious apprehension [Penn State Worry Questionnaire (PSWQ)]. Main and interaction effects of genotype, environment and gender on measures related to anxiety were assessed by means of regression analyses. Association analysis showed no main gene effect on either questionnaire score. A significant interactive effect of childhood adversities and COMT genotype was observed: Homozygosity for the low-active met allele and high CTQ scores was associated with a significant increment of explained ASI variance [R(2) = 0.040, false discovery rate (FDR) corrected P = 0.04]. A borderline interactive effect with respect to MAOA-uVNTR was restricted to the male subgroup. Carriers of the low-active MAOA allele who reported more aversive experiences in childhood exhibited a trend for enhanced anxious apprehension (R(2) = 0.077, FDR corrected P = 0.10). Early aversive life experiences therefore might increase the vulnerability to anxiety disorders in the presence of homozygosity for the COMT 158met allele or low-active MAOA-uVNTR alleles.

Fitness depends not only on resource uptake but also on the allocation of these resources to various life history functions. This study explores the life-history consequences of larval diet in terms not only of larval performance but also of adult body composition and reproductive traits in the forest tent caterpillar (Malacosoma disstria Hübner). Caterpillars were reared on their preferred tree host, trembling aspen (Populus tremuloides), or on one of three artificial foods: high protein:low carbohydrate, equal protein-to-carbohydrate ratio or low protein:high carbohydrate. Survivorship, larval development rate and adult body size were lowest on the carbohydrate-biased diet and similar on the protein-biased and equal-ratio diets. Fecundity increased with body size but did not otherwise differ between diets. Moths reared on the carbohydrate-biased diet allocated a lower proportion of their mass to the ovaries and more to somatic growth whereas those on equal-ratio and protein-biased diets allocated more to reproductive tissue and less to somatic tissue. These differences in allocation to reproduction arose from differences in the size of eggs, an index of offspring quality. No differences were found in lipid and protein content of female ovaries, accessory glands or somatic tissue, or of the whole body of male moths. The findings show that physiological processes regulate the composition of the different components of the adult body. Diet effects occur as differences in overall body size and in relative allocation to these components. Although lepidopterans can, to a large extent, compensate post-ingestively for nutritionally deficient diets, investment in reproduction vs somatic growth depends on the nutrients available.

Horace Wells was a Hartford, Connecticut, dentist whose practice flourished because of his clinical skills. He had an imaginative mind that propelled him to the forefront in several aspects of dentistry. Unfortunately, he suffered a recurrent "illness" that began in the winter and resolved in the spring. These symptoms were compatible with both major depressive disorder and seasonal affective disorder as a qualifier. Wells' introduction of nitrous oxide as an anesthetic was also associated with self-inhalation. This led to periods of hypomania, followed by depression. With the progression to ether, then chloroform, there was an episode of mania in January 1848, followed by depression and suicide.

Using Ecological Momentary Assessment, the within patient associations between drive for thinness, emotional states, momentary urge to be physically active and physical activity were studied in 32 inpatients with an eating disorder. Participants received an electronic device and had to indicate at nine random times a day during 1 week their momentary drive for thinness, positive and negative emotional states and their urge to be physically active and physical activity. Multilevel analyses indicated that patients with higher mean levels for urge to be physically active were characterized by lower body mass index (BMI) and chronically negative affect whereas patients with higher mean levels for physical activity were characterized by lower BMI and higher dispositions for drive for thinness. In addition, within patient relations between drive for thinness and urge to be physically active were moderated by BMI and chronically negative affect whereas within patient relations between drive for thinness and physical activity were moderated by BMI. Finally, also positive emotional states were significantly associated with physical activity within patients. By using a daily process design, characteristics of physical activity were revealed that have not been identified with assessment methods that have a lower time resolution.

Researchers around the world are developing sustainable plant-based liquid transportation fuels (biofuels) to reduce petroleum consumption and greenhouse gas emissions. Algae are attractive because they promise large yields per acre compared to grasses, grains and trees, and because they produce oils that might be converted to diesel and gasoline equivalents. It takes considerable energy to produce algal biofuels with current technology; thus, the potential benefits of algal biofuels compared to petroleum fuels must be quantified. To this end, we identified key parameters for algal biofuel production using GREET, a tool for the life-cycle analysis of energy use and emissions in transportation systems. The baseline scenario produced 55 400 g CO2 equivalent per million BTU of biodiesel compared to 101 000 g for low-sulfur petroleum diesel. The analysis considered the potential for greenhouse gas emissions from anaerobic digestion processes commonly used in algal biofuel models. The work also studied alternative scenarios, e.g., catalytic hydrothermal gasification, that may reduce these emissions. The analysis of the nitrogen recovery step from lipid-extracted algae (residues) highlighted the importance of considering the fate of the unrecovered nitrogen fraction, especially that which produces N2O, a potent greenhouse gas with global warming potential 298 times that of CO2.

Within species, larger offspring typically outperform smaller offspring. While the relationship between offspring size and performance is ubiquitous, the cause of this relationship remains elusive. By linking metabolic and life-history theory, we provide a general explanation for why larger offspring perform better than smaller offspring. Using high-throughput respirometry arrays, we link metabolic rate to offspring size in two species of marine bryozoan. We found that metabolism scales allometrically with offspring size in both species: while larger offspring use absolutely more energy than smaller offspring, larger offspring use proportionally less of their maternally derived energy throughout the dependent, non-feeding phase. The increased metabolic efficiency of larger offspring while dependent on maternal investment may explain offspring size effects—larger offspring reach nutritional independence (feed for themselves) with a higher proportion of energy relative to structure than smaller offspring. These findings offer a potentially universal explanation for why larger offspring tend to perform better than smaller offspring but studies on other taxa are needed. PMID:26559952

Among colonies of social insects, the worker turnover rate (colony ‘pace’) typically shows considerable variation. This has epidemiological consequences for parasites, because in ‘fast-paced’ colonies, with short-lived workers, the time of parasite residence in a given host will be reduced, and further transmission may thus get less likely. Here, we test this idea and ask whether pace is a life-history strategy against infectious parasites. We infected bumblebees (Bombus terrestris) with the infectious gut parasite Crithidia bombi, and experimentally manipulated birth and death rates to mimic slow and fast pace. We found that fewer workers and, importantly, fewer last-generation workers that are responsible for rearing sexuals were infected in colonies with faster pace. This translates into increased fitness in fast-paced colonies, as daughter queens exposed to fewer infected workers in the nest are less likely to become infected themselves, and have a higher chance of founding their own colonies in the next year. High worker turnover rate can thus act as a strategy of defence against a spreading infection in social insect colonies. PMID:26763696

Increasing sperm production per breeding male has economic significance with increasing use of artificial insemination. Manipulations to increase sperm production in livestock will only be useful if libido and sperm fertilizing capacity are not adversely affected. Reducing endogenous estrogens in the postnatal interval increases the number of Sertoli cells and hence testicular sperm production capacity. These experiments were designed to evaluate the effects of reducing endogenous estrogens on libido and sperm fertilizing capacity. Boars were treated with an aromatase inhibitor, letrozole, to reduce testicular estrogen production between 1 and 6 weeks of age or between 11 and 16 weeks of age, and the littermates to these boars were treated with the canola oil vehicle. Letrozole treatment did not affect time to first mount at 22 weeks of age, regardless of whether the treatment occurred from 1 to 6 weeks of age (118 seconds vs. 233 seconds, SEM = 161 for letrozole-treated and vehicle-treated boars, respectively) or from 11 to 16 weeks of age (107 seconds vs. 67 seconds, SEM = 63 for letrozole-treated and vehicle-treated boars, respectively). Similarly, sperm fertilizing ability and in vivo fertility were equivalent in letrozole-treated boars and their vehicle-treated littermates. Surprisingly, the increase in Sertoli cell numbers observed in the letrozole-treated boars at 20 weeks of age (5.8 vs. 4.3 billion, SEM = 0.5; P < 0.05) was not maintained to 40 weeks of age in their letrozole-treated littermates. Reducing endogenous estrogen production neonatally or prepuberally had no detectable adverse effect on libido or sperm fertilizing capacity.

Candidates for cardiac bypass surgery often experience cognitive decline. Such decline is likely to affect their everyday cognitive functioning. The aim of the present study was to compare cardiac patients' ratings of their everyday cognitive functioning against significant others' ratings and selected neuropsychological tests. Sixty-nine patients completed a battery of standardised cognitive tests. Patients and significant others also completed the Everyday Function Questionnaire independently of each other. Patient and significant other ratings of patients' everyday cognitive difficulties were found to be similar. Despite the similarities in ratings of difficulties, some everyday cognitive tasks were attributed to different processes. Patients' and significant others' ratings were most closely associated with the neuropsychological test of visual memory. Tests of the patients' verbal memory and fluency were only related to significant others' ratings. Test scores of attention and planning were largely unrelated to ratings by either patients or their significant others.

Early-life adversity is associated with accelerated cellular ageing during development and increased inflammation during adulthood. However, human studies can only establish correlation, not causation, and existing experimental animal approaches alter multiple components of early-life adversity simultaneously. We developed a novel hand-rearing paradigm in European starling nestlings (Sturnus vulgaris), in which we separately manipulated nutritional shortfall and begging effort for a period of 10 days. The experimental treatments accelerated erythrocyte telomere attrition and increased DNA damage measured in the juvenile period. For telomere attrition, amount of food and begging effort exerted additive effects. Only the combination of low food amount and high begging effort increased DNA damage. We then measured two markers of inflammation, high-sensitivity C-reactive protein and interleukin-6, when the birds were adults. The experimental treatments affected both inflammatory markers, though the patterns were complex and different for each marker. The effect of the experimental treatments on adult interleukin-6 was partially mediated by increased juvenile DNA damage. Our results show that both nutritional input and begging effort in the nestling period affect cellular ageing and adult inflammation in the starling. However, the pattern of effects is different for different biomarkers measured at different time points. PMID:28094324

Vacuum-packaging and stringent control of storage temperatures enable the export of meat to distant markets, supplying a chilled product that can favourably compete with local fresh meats. To save fuel and reduce emissions, the speed of ships travelling to international markets has decreased resulting in requirement for the shelf-life of chilled lamb to be extended beyond the recognised time of 60-70 days. Growth of microorganisms and ability to cause spoilage of vacuum-packed lamb are dependent on many factors, including the type and initial concentration of spoilage bacteria, meat pH, water activity, availability of substrates, oxygen availability and, most importantly, storage time and temperature of the packaged product. This paper reviews the existing knowledge of the spoilage bacteria affecting vacuum-packed lamb, discusses the impact of these bacteria on product quality, shelf-life and spoilage, and concludes that under specified conditions the shelf-life of chilled lamb can be extended to beyond 70 days.

In this work the influence of different packaging strategies on the shelf life of ready to use peeled shrimps was investigated. First, the effectiveness of the coating (Coat) and the active coating loaded with different concentrations of thymol (Coat-500, Coat-1000, and Coat-1500) on the quality loss of the investigated food product packaged in air was addressed; afterwards, the thymol concentration that had shown the best performance was used in combination with MAP (5% O(2); 95% CO(2)). Microbial cell load of main spoilage microorganisms, pH and sensorial quality were monitored during the refrigerated storage. Results of the first step suggested that the sole coating did not affect the microbial growth. A slight antimicrobial effect was obtained when the coating was loaded with thymol and a concentration dependence was also observed. Moreover, the active coating was effective in minimizing the sensory quality loss of the investigated product, it was particularly true at the lowest thymol concentration. In the second step, the thymol concentration (1000 ppm) that showed the strike balance between microbial and sensorial quality was chosen in combination with MAP. As expected, MAP significantly affected the growth of the mesophilic bacteria. In particular, a cell load reduction of about 2 log cycle for the samples under MAP respect to that in air was obtained. Moreover, the MAP packaging inhibited the growth of the Pseudomonas spp. and hydrogen sulphide-producing bacteria. The MAP alone was not able to improve the shelf life of the uncoated samples. In fact, no significant difference between the control samples packaged in air and MAP was observed. Whilst, the use of coating under MAP condition prolonged the shelf life of about 6 days with respect to the same samples packaged in air. Moreover, when the MAP was used in combination with thymol, a further shelf life prolongation with respect to the samples packaged in air was observed. In particular, a shelf life of

Background: Despite significant advances in pharmacological and psychological therapies for bipolar disorder, many people continue to have less than optimal outcomes, which are associated with significant disability and poor quality of life (QOL). This study aimed to assess the disability and QOL and factors associated with such suboptimal outcomes in subjects with bipolar disorder in remission. Methods: Consecutive patients diagnosed to have bipolar disorder in remission attending the Department of Psychiatry, MOSC Medical College, Kerala, India were recruited for the study. They were assessed using the International Classification of Diseases Diagnostic Criteria for Research-10, Hamilton Scale for Depression, Young's Mania Rating Scale, World Health Organization-QOL (WHO QOL-BREF), WHO-Disability Assessment Scale (WHO-DAS), and Kuppuswamy's scale for socioeconomic status assessment. Results: Eighty-four patients were evaluated. The mean total WHO-DAS score was 19.2 ± 2.09, the maximum disability in domain 4 (getting along) followed by domain 2 (mobility). The mean total WHO-QOL BREF score was 54.26 ± 2.85, the lowest subscore in domain 3 (social interactions). Disability scores were significantly associated with increasing age, female gender, not being an earning member of the family, and lower QOL scores. Poorer QOL scores were significantly associated with increasing age and higher disability score. Conclusions: Many bipolar patients in remission have significant disability and poorer QOL. There is a need for longitudinal studies to explore such associations and develop interventions to reduce the disability thereby enhancing the QOL. PMID:27570346

Telomeres are nucleotide sequences located at the ends of chromosomes that promote genome stability. Changes in telomere length (dynamics) are related to fitness or life expectancy, and telomere dynamics during the development phase are likely to be affected by growth and stress factors. Here, we examined telomere dynamics of black-tailed gull chicks (Larus crassirostris) in nests with and without siblings. We found that the initial telomere lengths of singletons at hatching were longer than those of siblings, indicating that singletons are higher-quality chicks than siblings in terms of telomere length. Other factors likely affecting individual quality (i.e., sex, laying date, laying order of eggs, and clutch size) were not related to telomere lengths. Within broods, initial telomere lengths were longer in older chicks than in younger chicks, suggesting that maternal effects, which vary with laying sequence, influence the initial lengths. Additionally, telomeres of chicks with a sibling showed more attrition between hatching and fledging than those of singleton chicks, suggesting that being raised with siblings can cause a sustained competitive environment that leads to telomere loss. High growth rates were associated with a low degree of telomere shortening observed in older siblings, perhaps because slower growth reflects higher food stress and/or higher aerobic metabolism from increased begging effort. Our results show that developmental telomere attrition was an inevitable consequence in two-chick nests in the pre- and post-hatching microenvironments due to the combination of social stress within the nest and maternal effects. The results of our study shed light on telomere dynamics in early life, which may represent an important physiological undercurrent of life-history traits. PMID:27902754

The life history and digestive α-amylase activity of the Angoumois grain moth, Sitotroga cerealella Olivier (Lepidoptera: Gelechiidae) were studied on six wheat cultivars (Arg, Bam, Nai 60, Pishtaz, Sepahan and Shanghai) at 25 ± 1°C, relative humidity of 65 ± 5% and a photoperiod of 16:8 (L:D) h. A delay in the developmental time of S. cerealella immature stages was detected when larvae were fed on cultivar Sepahan. The maximum survival rate of immature stages was seen on cultivar Bam (93.33 ± 2.10%), and the minimum rates were on cultivars Nai 60 (54.66 ± 2.49%) and Sepahan (49.33 ± 4.52%). The highest realized fecundity and fertility were recorded for females which came from larvae fed on cultivar Bam (93.30 ± 2.10 eggs/female and 91.90 ± 3.10%, respectively); and the lowest ones were observed for females which came from larvae fed on cultivar Sepahan (49.30 ± 4.50 eggs/female and 67.4 ± 11.1%, respectively). The heaviest male and female weights of S. cerealella were observed on cultivar Bam (2.97 ± 0.02 and 4.80 ± 0.01 mg, respectively). The highest amylolytic activity of the fourth instar was detected on cultivar Bam (0.89 ± 0.04 mg maltose min-1), which had the maximum mean hundred-wheat weight (5.92 ± 0.19 g). One α-amylase isozyme was detected in the midgut extracts from the fourth instar larvae fed on different wheat cultivars, and the highest intensity was found in larvae fed on cultivar Bam. Correlation analyses showed that very high correlations existed between the immature period, fecundity and fertility on one side and inhibition of α-amylase, soluble starch content and hundred-wheat weight on the other. According to the obtained results, cultivar Sepahan is an unfavorable host for the feeding and development of S. cerealella.

Increases in the frequency, duration and intensity of heat waves are frequently evoked in climate change predictions. However, there is no universal definition of a heat wave. Recent, intense hot weather events have caused mass mortalities of birds, bats and even humans, making the definition and prediction of heat wave events that have the potential to impact populations of different species an urgent priority. One possible technique for defining biologically meaningful heat waves is to use threshold temperatures (T(thresh)) above which known fitness costs are incurred by species of interest. We set out to test the utility of this technique using T(thresh) values that, when exceeded, affect aspects of the fitness of two focal southern African bird species: the southern pied babbler Turdiodes bicolor (T(thresh) = 35.5 °C) and the common fiscal Lanius collaris (T(thresh) = 33 °C). We used these T(thresh) values to analyse trends in the frequency, duration and intensity of heat waves of magnitude relevant to the focal species, as well as the annual number of hot days (maximum air temperature > T(thresh)), in north-western South Africa between 1961 and 2010. Using this technique, we were able to show that, while all heat wave indices increased during the study period, most rapid increases for both species were in the annual number of hot days and in the maximum intensity (and therefore intensity variance) of biologically meaningful heat waves. Importantly, we also showed that warming trends were not uniform across the study area and that geographical patterns in warming allowed both areas of high risk and potential climate refugia to be identified. We discuss the implications of the trends we found for our focal species, and the utility of the T(thresh) technique as a conservation tool.
In nature, very few species are common and broadly distributed. Most species are rare and occupy few sites; this pattern is ubiquitous across habitats and taxa. In spatially structured communities (metacommunities), regional distribution and local abundance may change as the relative effects of within-habitat processes (e.g., species interactions) and among-habitat processes (e.g., dispersal) may vary through succession. A field experiment with the marine benthic inhabitants of pen shells (Atrina rigida) tested how common and rare species respond to succession and metacommunity size. I followed community development through time and partitioned species into sessile and motile based on their natural history. Rare species drive diversity patterns and are influenced by metacommunity size: there are strong abundance-distribution differences between common and rare species in large metacommunities, but motile species show lower rates of change than sessile species. In small metacommunities both common and rare species have similar changes through time; the dichotomous distinction of common and rare species is not present. Edge effects in metacommunities affect species' changes in distribution and abundance. In large metacommunities diversity is higher in edge habitats relative to small metacommunities during early succession. However, edge effects benefit motile species over time in small metacommunities showing a rapid increase in diversity. Individual mobility is sensitive to regional community size and allows individuals to sort among different communities. In contrast, sessile species do not show this edge effect. Metacommunity theory is a useful framework for understanding spatially structured communities, but the natural history of coexisting species cannot be ignored.

Early life adversity has known impacts on adult health and behavior, yet little is known about the gene-environment interactions (GEIs) that underlie these consequences. We used the fruit fly Drosophila melanogaster to show that chronic early nutritional adversity interacts with rover and sitter allelic variants of foraging (for) to affect adult exploratory behavior, a phenotype that is critical for foraging, and reproductive fitness. Chronic nutritional adversity during adulthood did not affect rover or sitter adult exploratory behavior; however, early nutritional adversity in the larval period increased sitter but not rover adult exploratory behavior. Increasing for gene expression in the mushroom bodies, an important center of integration in the fly brain, changed the amount of exploratory behavior exhibited by sitter adults when they did not experience early nutritional adversity but had no effect in sitters that experienced early nutritional adversity. Manipulation of the larval nutritional environment also affected adult reproductive output of sitters but not rovers, indicating GEIs on fitness itself. The natural for variants are an excellent model to examine how GEIs underlie the biological embedding of early experience.

Phenotypic plasticity can have strong impacts on predator-prey interactions. Although much work has examined the effects of inducible defences, less understood is how inducible offences in predators affect predator-prey interactions and predator and prey phenotypes. Here, we examine the impacts of an inducible offence on the interactions and life histories of a cohort of predatory Hynobius retardatus salamander larvae and their prey, Rana pirica tadpoles. We examined larval (duration, survival) and post-metamorphic (size) traits of both species after manipulating the presence/absence of tadpoles and salamanders with offensive (broadened gape width) or non-offensive phenotypes in pond enclosures. Offensive phenotype salamanders reduced tadpole survival and metamorph emergence by 58% compared to tadpole-only treatments, and by over 30% compared to non-offensive phenotypes. Average time to metamorphosis of frogs was delayed by 30% in the presence of salamanders, although this was independent of salamander phenotype. Thus, offensive phenotype salamanders reduced the number of tadpoles remaining in the pond over time by reducing tadpole survival, not by altering patterns of metamorph emergence. Offensive phenotypes also caused tadpoles to metamorphose 19% larger than no salamander treatments and 6% larger than non-offensive phenotype treatments. Pooled across salamander treatments, tadpoles caused salamanders to reach metamorphosis faster and larger. Moreover, in the presence of tadpoles, offensive phenotype salamanders metamorphosed 25% faster and 5% larger than non-offensive phenotype salamanders, but in their absence, neither their size nor larval period differed from non-offensive phenotype individuals. To our knowledge, this study is the first to demonstrate that inducible offences in predators can have strong impacts on predator and prey phenotypes across multiple life stages. Since early metamorphosis at a larger size has potential fitness advantages, the impacts

Drawing on the sociology of morality, this article analyses the social contexts, discourses and ethno-methods of everyday life that shape real-world decisions of gay men around HIV prevention. Through an analysis of the predominant narratives in an online public forum created for an HIV prevention campaign, this article explores the ways in which homosexually active men engage in everyday moral reasoning and challenge a neoliberal moral order of risk and responsibility. The article concludes that gay and bisexual men engage in forms of practical morality with their sexual partners and imagine larger communities of interest, love, companionship and pleasure. At the same time, they draw heavily from discourses on individual and rational responsibility, as well as narratives of romance and community, that shape forms of moral selfhood. Risk management techniques that are grounded in notions of rational choice and that are insensitive to the emotional worlds that these men inhabit create situations of risk avoidance but also inadvertently open them to new forms of vulnerability.
Lyrics for Bob Dylan's songs between 1962 and 2001 (close to 100,000 words) were scored with the help of the Dictionary of Affect in Language (Whissell, 2006). Means for Pleasantness, Activation, and Imagery are reported for 22 Blocks characterizing this time span. Significant but weak differences across Blocks were found for all three measures at the level of individual words. Emotional fluctuations in words included in Bob Dylan's lyrics accompanied events and phases in his life, although they were not entirely dictated by these events. Dylan used more highly Imaged and more Active words at times when his work was critically acclaimed. More Passive word choices characterized times of prolonged stress, and more Pleasant choices times of experimentation. Dylan's three popularity peaks were used to divide the singer's career into three stages (rhetor, poet, sage) which differed in terms of pronouns used.

We evaluated whether life-time exposure to PFOS affects egg development, hatching, larval development, survival, metamorphosis and body mass of Enallagma cyathigerum (Insecta: Odonata). Eggs and larvae were exposed to five concentrations ranging from 0 to 10000 microg/L. Our results show reduced egg hatching success, slower larval development, greater larval mortality, and decreased metamorphosis success with increasing PFOS concentration. PFOS had no effect on egg developmental time and hatching or on mass of adults. Eggs were the least sensitive stage (NOEC=10000 microg/L). Larval NOEC values were 1000 times smaller (10 microg/L). Successful metamorphosis was the most sensitive response trait studied (NOEC<10 microg/L). The NOEC value suggests that E. cyathigerum is amongst the most sensitive freshwater organisms tested. NOEC for metamorphosis is less than 10-times greater than the ordinary reported environmental concentrations in freshwater, but is more than 200-times smaller than the greatest concentrations measured after accidental releases.

Previous cross-sectional research has shown that older people who are rich in sensorimotor-cognitive and social-personality resources are better functioning in everyday life and exhibit fewer negative age differences than resource-poor adults. Longitudinal data from the Berlin Aging Study was used to examine these findings across a 4-year time interval and to compare cross-sectional indicators of adaptive everyday functioning among survivors and nonsurvivors. Apart from their higher survival rate, resource-rich older people (a) invest more social time with their family members, (b) reduce the diversity of activities within the most salient leisure domain, (c) sleep more often and longer during daytime, and (d) increase the variability of time investments across activities after 4 years. Overall, findings suggest a greater use of selection, compensation, and optimization strategies in everyday functioning among resource-rich older adults as compared with resource-poor older adults.

Objectives To review systematically the evidence of age-related macular degeneration (AMD) affecting real-world visual ability and quality of life (QoL). To explore trends in specific topics within this body of the literature. Design Systematic review. Methods A systematic literature search was carried out using MEDLINE, EMBASE, CINAHL, PsycINFO, PsychARTICLES and Health and Psychosocial Instruments for articles published up to January 2015 for studies including people diagnosed with AMD, assessing real-world visual ability or QoL as an outcome. Two researchers screened studies for eligibility. Details of eligible studies including study design, characteristics of study population and outcomes measured were recorded in a data extraction table. All included studies underwent quality appraisal using the Mixed Methods Appraisal Tool 2011 Version (MMAT). Results From 5284 studies, 123 were eligible for inclusion. A range of approaches were identified, including performance-based methods, quantitative and qualitative patient-reported outcome measures (PROMs). AMD negatively affects tasks including mobility, face recognition, perception of scenes, computer use, meal preparation, shopping, cleaning, watching TV, reading, driving and, in some cases, self-care. There is evidence for higher rates of depression among people with AMD than among community dwelling elderly. A number of adaptation strategies have been associated with AMD of varying duration. Much of the research fails to report the type of AMD studied (59% of included studies) or the duration of disease in participants (74%). Of those that do report type studied, the breakdown is as follows: wet AMD 20%, dry AMD 4% and both types 17%. Conclusions There are many publications highlighting the negative effects of AMD in various domains of life. Future research should focus on delivering some of this research knowledge into patient management and clinical trials and differentiating between the types of AMD. PMID

Background: Physical activity and mental health could be affected by osteoporosis and various therapeutic options such as calcitonin may influence Quality Of Life (QOL) of these patients with Low Bone Density (LBD). Objectives: This study aimed to evaluate the effect of nasal calcitonin on QOL in post menopause women with LBD. Patients and Methods: This clinical trial study was performed on one hundred and fifteen menopause women with LBD less than 1 SD in Bone Mineral Densitometry (BMD) referred to Baqiyatallah Hospital in Tehran, Iran, during 2009 - 2010. They were assigned to receive 200 IU calcitonin nasal spray along with calcium (1000 mg) and vitamin D (400 IU) for 6 months. Quality of life was assessed by Short-Form 36 (SF-36) questionnaire (Persian-validated version). Results: The mean age (± SD) of the participants was 58.75 ± 8.15 years. Intranasal spray of calcitonin increased QOL scores significantly (88.05 ± 15.63 vs. 92.15 ± 13.22, P value = 0.000). Bone mineral density of spine was increased from 0.834 ± 0.11 to 0.12 ± 0.852 and this difference in BMD of lumbar spine was statistically significant (P value: 0.003) but not significant in femur’s BMD (P value = 0.061). In comparison with BMD indexes, The QOL scores especially Mental Health domain changes had only a significant correlation with the changes of total T score in BMD (P = 0.031, Coefficient Correlation = 0.248). Conclusions: It seems that nasal spray of calcitonin can effectively improve QOL of women with LBD and QOL changes were not influenced by clinical or para-clinical alteration. Mental health domain must be more considered in further studies as a predicting domain for Health-Related Quality of Life (HR-QOL) changes. PMID:26421180

A vast body of literature exists documenting the morphological, behavioural and life history changes that predators induce in prey. However, little attention has been paid to how these induced changes feed back and affect the predators' life history and morphology. Larvae of the phantom midge Chaoborus flavicans are intermediate predators in a food web with Daphnia pulex as the basal resource and planktivorous fish as the top predator. C. flavicans prey on D. pulex and are themselves prey for fish; as D. pulex induce morphological defences in the presence of C. flavicans this is an ideal system in which to evaluate the effects of defended prey and top predators on an intermediate consumer. We assessed the impact on C. flavicans life history and morphology of foraging on defended prey while also being exposed to the non-lethal presence of a top fish predator. We tested the basic hypothesis that the effects of defended prey will depend on the presence or absence of top predator predation risk. Feeding rate was significantly reduced and time to pupation was significantly increased by defended morph prey. Gut size, development time, fecundity, egg size and reproductive effort respond to fish chemical cues directly or significantly alter the relationship between a trait and body size. We found no significant interactions between prey morph and the non-lethal presence of a top predator, suggesting that the effects of these two biological factors were additive or singularly independent. Overall it appears that C. flavicans is able to substantially modify several aspects of its biology, and while some changes appear mere consequences of resource limitation others appear facultative in nature.

Background and Aims Flooding can occur at any stage of the life cycle of a plant, but often adaptive responses of plants are only studied at a single developmental stage. It may be anticipated that juvenile plants may respond differently from mature plants, as the amount of stored resources may differ and morphological changes can be constrained. Moreover, different water depths may require different strategies to cope with the flooding stress, the expression of which may also depend on developmental stage. This study investigated whether flooding-induced adventitious root formation and plant growth were affected by flooding depth in Solanum dulcamara plants at different developmental stages. Methods Juvenile plants without pre-formed adventitious root primordia and mature plants with primordia were subjected to shallow flooding or deep flooding for 5 weeks. Plant growth and the timing of adventitious root formation were monitored during the flooding treatments. Key Results Adventitious root formation in response to shallow flooding was significantly constrained in juvenile S. dulcamara plants compared with mature plants, and was delayed by deep flooding compared with shallow flooding. Complete submergence suppressed adventitious root formation until up to 2 weeks after shoots restored contact with the atmosphere. Independent of developmental stage, a strong positive correlation was found between adventitious root formation and total biomass accumulation during shallow flooding. Conclusions The potential to deploy an escape strategy (i.e. adventitious root formation) may change throughout a plant’s life cycle, and is largely dependent on flooding depth. Adaptive responses at a given stage of the life cycle thus do not necessarily predict how the plant responds to flooding in another growth stage. As variation in adventitious root formation also correlates with finally attained biomass, this variation may form the basis for variation in resistance to shallow

1. Examining the demographic responses of populations to disease epidemics and the nature of compensatory responses to perturbation from epidemics is critical to our understanding of the processes affecting population dynamics and our ability to conserve threatened species. Such knowledge is currently available for few systems. 2. We examined changes to the demography and life-history traits of a population of Tasmanian devils (Sarcophilus harrisii) following the arrival of a debilitating infectious disease, devil facial tumour disease (DFTD), and investigated the population's ability to compensate for the severe population perturbation caused by this epizootic. 3. There was a significant change to the age structure following the arrival of DFTD to the Freycinet Peninsula. This shift to a younger population was caused by the loss of older individuals from the population as a direct consequence of DFTD-driven declines in adult survival rates. 4. Offspring sex ratios of disease mothers were more female biased than those of healthy mothers, indicating that devils may facultatively adjust offspring sex ratios in response to disease-induced changes in maternal condition. 5. We detected evidence of reproductive compensation in response to disease impacts via a reduction in the age of sexual maturity of females (an increase in precocial breeding) over time. 6. The strength of this compensatory response appeared to be limited by factors that constrain the ability of individuals to reach a critical size for sexual maturity in their first year, because of the time limit dictated by the annual breeding season. 7. The ongoing devastating impacts of this disease for adult survival and the apparent reliance of precocial breeding on rapid early growth provide the opportunity for evolution to favour of this new life-history pattern, highlighting the potential for novel infectious diseases to be strong selective forces on life-history evolution.

The "New Variant Famine" hypothesis proposed that AIDS offers a major challenge to food security in this part of Africa by impairing the functioning of traditional support systems, leading to the collapse of "social immunity". This study explores the changing perceptions of HIV and AIDS and peoples' responses to its impact by eliciting life history narratives of 30 respondents in Northern Malawi. We classified respondents by means of gender, livelihood systems and AIDS impact levels. Respondents reported a range of critical events, recorded in the life histories, that threatened their "social immunity", including deaths, sicknesses, migration, marriages and divorces, and dropping out of school; i.e., a greater range of risks than AIDS alone, that need to be recognised in HIV and AIDS programming. For the respondents who were classified as "AIDS-affected", learning about their seropositive status was found to be an important, and in some cases a positive, turning point in their lives in terms of behavioural changes, such as joining support groups and opening up to discussion of the implications of their status. The emerging social organisations could re-create social capacity and check the downward spiral proposed by the "New Variant Famine" hypothesis. To promote this shift and to confer a higher level of "social immunity", investments in expanding access to voluntary counselling and testing and antiretroviral therapy services, and assistance to community-based organisations would be essential.

The effect of three chemicals with different mechanisms of action (3,4-dichloroaniline, fenoxycarb, and chlorpyrifos) on the life history response of the cladoceran Ceriodaphnia cf. dubia was examined under both limited (3 x 10(4) cells/mL) and abundant (15 x 10(4) cells/mL) food conditions. Toxicity tests were conducted at both food concentrations simultaneously for each chemical, and cladocerans were examined daily from less than 24 h old until their death. A range of life history parameters were calculated, including mean brood sizes, survival, net reproductive rate, and population growth rate. The toxicity of 3,4-dichloroaniline was not significantly affected by food concentration. However, limited food significantly decreased the toxicity of fenoxycarb, and significantly increased the toxicity of chlorpyrifos. The effect of food concentration on toxicity appears to depend on the mechanism by which the chemical exerts its toxicity and on food--chemical interactions. Possible mechanisms for the different effects of food concentration on toxicity are discussed.
The mainstream economy and culture are unable to compete with the money, respect, and identity that selling crack offers. The infiltration of organized crime and narco-dollars into the local economy, the inadequacy of entry-level wages, and the breakdown of basic public services have created a new kind of poverty. (CJS)

There are many pitfalls associated with teaching about religions. One such pitfall entails the risk of presenting religions as stereotypical monolithic systems; that is, all who belong to a particular religious tradition think and act in the same way. I like to call this sort of stereotyping the "robotic tendency" because it has a habit…

Background Titanium dioxide (TiO2) is considered as an inert and safe material and has been used in many applications for decades. However, with the development of nanotechnologies TiO2 nanoparticles, with numerous novel and useful properties, are increasingly manufactured and used. Therefore increased human and environmental exposure can be expected, which has put TiO2 nanoparticles under toxicological scrutiny. Mechanistic toxicological studies show that TiO2 nanoparticles predominantly cause adverse effects via induction of oxidative stress resulting in cell damage, genotoxicity, inflammation, immune response etc. The extent and type of damage strongly depends on physical and chemical characteristics of TiO2 nanoparticles, which govern their bioavailability and reactivity. Based on the experimental evidence from animal inhalation studies TiO2 nanoparticles are classified as “possible carcinogenic to humans” by the International Agency for Research on Cancer and as occupational carcinogen by the National Institute for Occupational Safety and Health. The studies on dermal exposure to TiO2 nanoparticles, which is in humans substantial through the use of sunscreens, generally indicate negligible transdermal penetration; however data are needed on long-term exposure and potential adverse effects of photo-oxidation products. Although TiO2 is permitted as an additive (E171) in food and pharmaceutical products we do not have reliable data on its absorption, distribution, excretion and toxicity on oral exposure. TiO2 may also enter environment, and while it exerts low acute toxicity to aquatic organisms, upon long-term exposure it induces a range of sub-lethal effects. Conclusions Until relevant toxicological and human exposure data that would enable reliable risk assessment are obtained, TiO2 nanoparticles should be used with great care. PMID:22933961

The aim of this study was to identify and describe the characteristics of the difficulties using everyday technology in persons with an aquired brain injury (ABI), and their experiences of how these difficulties influenced their life. Thirteen persons with an ABI were interviewed about their difficulties in using everyday technology and were observed in their use of technology. Data were analysed qualitatively with a constant comparative method. The results showed that the persons' experiences formed two categories: “A variety of combinations of difficulties in the use of everyday technology” and “Restrictions in life”. The difficulties identified were related not only to everyday technology itself but also to the interaction between the technology, the task, the person, and the environment. These difficulties influenced their experiences of restrictions in occupational performance, personal identification, and participation in society. The results emphasize that occupational therapists who design interventions for people with an ABI need to accommodate both the technology and other interacting aspects in order to overcome difficulties in using everyday technology.

Background When functional impairment occurs, assistance to achieve self-help can lead to qualitatively more active everyday life for recipients and better use of community resources. Home-based everyday rehabilitation is a new interdisciplinary service for people living at home. Rehabilitation involves meeting the need for interprofessional services, interdisciplinary collaboration, and coordination of services. Everyday rehabilitation is a service that requires close interdisciplinary cooperation. The purpose of this study was to gain knowledge about employees’ experiences with establishing a new multidisciplinary team and developing a team-based work model. Method The study had a qualitative design using two focus group interviews with a newly established rehabilitation team. The sample consisted of an occupational therapist, two care workers with further education in rehabilitation, a nurse, a physiotherapist, and a project leader. Data were analyzed by thematic content analysis. Results The data highlight three phases: a planning phase (ten meetings over half a year), a startup phase of trials of interdisciplinary everyday rehabilitation in practice (2 months), and a third period specifying and implementing an everyday rehabilitation model (6 months). During these phases, three themes emerged: 1) team creation and design of the service, 2) targeted practical trials, and 3) equality of team members and combining interdisciplinary methods. Conclusion The team provided information about three processes: developing work routines and a revised team-based flow chart, developing team cooperation with integrated Trans- and interdisciplinary collaboration, and working with external exchange. There is more need for secure network solutions. PMID:27143911

Ty3, a retroviruslike element of Saccharomyces cerevisiae, transposes into positions immediately upstream of RNA polymerase III-transcribed genes. The Ty3 integrase (IN) protein is required for integration of the replicated, extrachromosomal Ty3 DNA. In retroviral IN, a conserved core region is sufficient for strand transfer activity. In this study, charged-to-alanine scanning mutagenesis was used to investigate the roles of the nonconserved amino- and carboxyl-terminal regions of Ty3 IN. Each of the 20 IN mutants was defective for transposition, but no mutant was grossly defective for capsid maturation. All mutations affecting steady-state levels of mature IN protein resulted in reduced levels of replicated DNA, even when polymerase activity was not grossly defective as measured by exogenous reverse transcriptase activity assay. Thus, IN could contribute to nonpolymerase functions required for DNA production in vivo or to the stability of the DNA product. Several mutations in the carboxyl-terminal domain resulted in relatively low levels of processed 3′ ends of the replicated DNA, suggesting that this domain may be important for binding of IN to the long terminal repeat. Another class of mutants produced wild-type amounts of DNA with correctly processed 3′ ends. This class could include mutants affected in nuclear entry and target association. Collectively, these mutations demonstrate that in vivo, within the preintegration complex, IN performs a central role in coordinating multiple late stages of the retrotransposition life cycle.

Quantifying the fitness cost that parasites impose on wild hosts is a challenging task, because the epidemiological history of field-sampled hosts is often unknown. In this study, we used an internal marker of the parasite pressure on individual hosts to evaluate the costs of parasitism with respect to host body condition, size increase and reproductive potential of field-collected animals for which we also determined individual age. In our investigated system, the European eel Anguilla anguilla and the parasitic invader Anguillicoloides crassus, high virulence and severe impacts are expected because the host lacks an adaptive immune response. We demonstrated a nonlinear relationship between the severity of damage to the affected organ (i.e. the swimbladder, our internal marker) and parasite abundance and biomass, thus showing that the use of classical epidemiological parameters was not relevant here. Surprisingly, we found that the most severely affected eels (with damaged swimbladder) had greater body length and mass (+11% and +41%, respectively), than unaffected eels of same age. We discuss mechanisms that could explain this finding and other counterintuitive results in this host–parasite system, and highlight the likely importance of host panmixia in generating great inter-individual variability in growth potential and infection risk. Under that scenario, the most active foragers would not only have the greatest size increase, but also the highest probability of becoming repeatedly infected—via trophic parasite transmission—during their continental life.

In two everyday experience studies, we examined the degree to which everyday social comparisons are framed by group membership. In the first study, 30 undergraduates attending a public university in the United States completed short questionnaires about their social comparison experiences whenever they were signalled. In the second study, 34 ethnic minority undergraduates from the same university completed similar questionnaires about their social comparison experiences. Across both studies, comparisons in which participants viewed themselves as an ingroup member in comparison to an outgroup comprised less than 10% of the comparison experiences reported by participants. However, minorities in the second study who reported closer identification with their ethnic group reported more comparison experiences in which they mentioned their own or the comparison target's ethnicity.

Background. An important outcome from the debate on whether wellness equals happiness, is the need of research focusing on how psychological well-being might influence humans' ability to adapt to the changing environment and live in harmony. To get a detailed picture of the influence of positive and negative affect, the current study employed the affective profiles model in which individuals are categorised into groups based on either high positive and low negative affect (self-fulfilling); high positive and high negative affect (high affective); low positive and low negative affect (low affective); and high negative and low positive affect (self-destructive). The aims were to (1) investigate differences between affective profiles in psychological well-being and harmony and (2) how psychological well-being and its dimensions relate to harmony within the four affective profiles. Method. 500 participants (mean age = 34.14 years, SD. = ±12.75 years; 187 males and 313 females) were recruited online and required to answer three self-report measures: The Positive Affect and Negative Affect Schedule; The Scales of Psychological Well-Being (short version) and The Harmony in Life Scale. We conducted a Multivariate Analysis of Variance where the affective profiles and gender were the independent factors and psychological well-being composite score, its six dimensions as well as the harmony in life score were the dependent factors. In addition, we conducted four multi-group (i.e., the four affective profiles) moderation analyses with the psychological well-being dimensions as predictors and harmony in life as the dependent variables. Results. Individuals categorised as self-fulfilling, as compared to the other profiles, tended to score higher on the psychological well-being dimensions: positive relations, environmental mastery, self-acceptance, autonomy, personal growth, and purpose in life. In addition, 47% to 66% of the variance of the harmony in life was explained by the

This paper reports on 6-11-year-old children's `sayings and doings' (Harré 2002) as they explore molecule artefacts in dialectical-interactive teaching interviews (Fleer, Cultural Studies of Science Education 3:781-786, 2008; Hedegaard et al. 2008). This sociocultural study was designed to explore children's everyday awareness of and meaning-making with cultural molecular artefacts. Our everyday world is populated with an ever increasing range of molecular or nanoworld words, symbols, images, and games. What do children today say about these artefacts that are used to represent molecular world entities? What are the material and social resources that can influence a child's everyday and developing scientific ideas about `molecules'? How do children interact with these cognitive tools when given expert assistance? What meaning-making is afforded when children are socially and materially assisted in using molecular tools in early chemical and nanoworld thinking? Tool-dependent discursive studies show that provision of cultural artefacts can assist and direct developmental thinking across many domains of science (Schoultz et al., Human Development 44:103-118, 2001; Siegal 2008). Young children's use of molecular artefacts as cognitive tools has not received much attention to date (Jakab 2009a, b). This study shows 6-11-year-old children expressing everyday ideas of molecular artefacts and raising their own questions about the artefacts. They are seen beginning to domesticate (Erneling 2010) the words, symbols, and images to their own purposes when given the opportunity to interact with such artefacts in supported activity. Discursive analysis supports the notion that using `molecules' as cultural tools can help young children to begin `putting on molecular spectacles' (Kind 2004). Playing with an interactive game (ICT) is shown to be particularly helpful in assisting children's early meaning-making with representations of molecules, atoms, and their chemical symbols.

Key to predicting impacts of predation is understanding the mechanisms through which predators impact prey populations. While consumptive effects are well-known, non-consumptive predator effects (risk effects) are increasingly being recognized as important. Studies of risk effects, however, have focused largely on how trade-offs between food and safety affect fitness. Less documented, and appreciated, is the potential for predator presence to directly suppress prey reproduction and affect life-history characteristics. For the first time, we tested the effects of visual predator cues on reproduction of two prey species with different reproductive modes, lecithotrophy (i.e. embryonic development primarily fueled by yolk) and matrotrophy (i.e. energy for embryonic development directly supplied by the mother to the embryo through a vascular connection). Predation risk suppressed reproduction in the lecithotrophic prey (Gambusia holbrokii) but not the matrotroph (Heterandria formosa). Predator stress caused G. holbrooki to reduce clutch size by 43%, and to produce larger and heavier offspring compared to control females. H. formosa, however, did not show any such difference. In G. holbrooki we also found a significantly high percentage (14%) of stillbirths in predator-exposed treatments compared to controls (2%). To the best of our knowledge, this is the first direct empirical evidence of predation stress affecting stillbirths in prey. Our results suggest that matrotrophy, superfetation (clutch overlap), or both decrease the sensitivity of mothers to environmental fluctuation in resource (food) and stress (predation risk) levels compared to lecithotrophy. These mechanisms should be considered both when modeling consequences of perceived risk of predation on prey-predator population dynamics and when seeking to understand the evolution of reproductive modes.

Science education faces two major challenges: the perceived relevance of science to people's everyday live and ensuring that all students can obtain high quality science instruction. This dissertation explores how making connections between school science and students' everyday lives can lead to higher quality science education. It explores how a class of 4 th grade students makes connections between school science and their everyday lives. Drawing on a sociocultural perspective, I conceptualize learning as entering into a community of practice. I investigate how the affordances and constraints of three activities shaped students' opportunities to learn. In particular, I examine when and how students and teachers drew on students' funds of knowledge and created hybrid spaces. To this end, I examine (1) the object of the activity -- the task and its' parameters, and (2) the participation framework -- how the students and teacher are positioned in the activity and the discourse structures. I discuss how the object of the activity and the participation framework and the interaction between the two aspects provided opportunities for the students and teacher to make connections between students' funds of knowledge and school science and merge them to create hybrid spaces. I conclude with a discussion of the themes that arose from the study and the implications for teaching and learning.

People typically want to feel good. At times, however, they seek to maintain or enhance negative affect or to dampen positive affect. The prevalence of such contrahedonic motivation has been related to simultaneous experiences of positive and negative (i.e., mixed) affect. We investigated the role that implicit mental representations of affect valence may play in this regard in a study with N = 400 participants aged 11-88 years. Results demonstrated the age-fairness and reliability of the affect-valence Implicit Association Test, a newly developed implicit measure of interindividual differences in mental representations of affect valence. The older participants were, the more distinctively they implicitly associated happiness with pleasantness and/or unhappiness with unpleasantness. Participants furthermore carried mobile phones as assessment instruments with them for 3 weeks while pursuing their daily routines. The phones prompted participants on average 54 times to report their momentary affective experience and affect-regulation motivation. Contrahedonic motivation and mixed affect were most prevalent among adolescents and least prevalent among older adults, and thus showed a similar pattern of age differences as the affect-valence Implicit Association Test. Furthermore, the more distinctive participants' implicit associations of happiness with pleasantness, and/or unhappiness with unpleasantness, the less likely participants were to report contrahedonic motivation and mixed affect in their daily lives. These findings contribute to a refined understanding of the mixed-affect perspective on contrahedonic motivation by demonstrating the respective role of implicit affect-valence representations.

Six- and 12-month-old infant's eye movements were recorded as they observed feeding actions being performed in a rational or non-rational manner. Twelve-month-olds fixated the goal of these actions before the food arrived (anticipation); the latency of these gaze shifts being dependent (r=.69) on infants life experience being feed. In addition, 6- and 12-month-olds dilated their pupil during observation of non-rational feeding actions. This effect could not be attributed to light differences or differences in familiarity, but was interpreted to reflect sympathetic-like activity and arousal caused by a violation of infant's expectations about rationality. We argue that evaluation of rationality requires less experience than anticipations of action goals, suggesting a dual process account of preverbal infants' everyday action understanding.

When determining the cause of a person’s behavior, perceivers often overweigh dispositional explanations and underweigh situational explanations, an error known as the Fundamental Attribution Error (FAE). The FAE occurs in part because dispositional explanations are relatively automatic, whereas considering the situation requires additional cognitive effort. Stress is known to impair the prefrontal cortex and executive functions important for the attribution process. We investigated if stress increases dispositional attributions in common place and legal situations. Experiencing a physiological stressor increased participants’ cortisol, dispositional attributions of common everyday behaviors, and negative evaluations. When determining whether a crime was due to the defendant’s disposition or the mitigating situation, self-reported stress correlated with increased dispositional judgments of defendant’s behavior. These findings indicate that stress may makes people more likely to commit the FAE and less favorable in their evaluations of others both in daily life and when making socially consequential judicial decisions.

Posterior cortical atrophy (PCA) is a neurodegenerative syndrome characterized by progressive visual dysfunction and parietal, occipital, and occipitotemporal atrophy. The aim of this study was to compare the impact of PCA and typical Alzheimer's disease (tAD) on everyday functional abilities and neuropsychiatric status. The Cambridge Behavioural Inventory-Revised was given to carers of 32 PCA and 71 tAD patients. PCA patients showed significantly greater impairment in everyday skills and self-care while the tAD group showed greater impairment in aspects of memory and orientation, and motivation. We suggest that PCA poses specific challenges for those caring for people affected by the condition.

Individuals with adductor spasmodic dysphonia (ADSD) have reported that unfamiliar communication partners appear to judge them as sneaky, nervous or not intelligent, apparently based on the quality of their speech; however, there is minimal research into the actual everyday perspective of listening to ADSD speech. The purpose of this study was to investigate the impressions of listeners hearing ADSD speech for the first time using a mixed-methods design. Everyday listeners were interviewed following sessions in which they made ratings of ADSD speech. A semi-structured interview approach was used and data were analyzed using thematic content analysis. Three major themes emerged: (1) everyday listeners make judgments about speakers with ADSD; (2) ADSD speech does not sound normal to everyday listeners; and (3) rating overall severity is difficult for everyday listeners. Participants described ADSD speech similarly to existing literature; however, some listeners inaccurately extrapolated speaker attributes based solely on speech samples. Listeners may draw erroneous conclusions about individuals with ADSD and these biases may affect the communicative success of these individuals. Results have implications for counseling individuals with ADSD, as well as the need for education and awareness about ADSD.

Ocean Acidification (OA) has been shown to affect photosynthesis and calcification in the coccolithophore Emiliania huxleyi, a cosmopolitan calcifier that significantly contributes to the regulation of the biological carbon pumps. Its non-calcifying, haploid life-cycle stage was found to be relatively unaffected by OA with respect to biomass production. Deeper insights into physiological key processes and their dependence on environmental factors are lacking, but are required to understand and possibly estimate the dynamics of carbon cycling in present and future oceans. Therefore, calcifying diploid and non-calcifying haploid cells were acclimated to present and future CO2 partial pressures (pCO2; 38.5 Pa vs. 101.3 Pa CO2) under low and high light (50 vs. 300 µmol photons m−2 s−1). Comparative microarray-based transcriptome profiling was used to screen for the underlying cellular processes and allowed to follow up interpretations derived from physiological data. In the diplont, the observed increases in biomass production under OA are likely caused by stimulated production of glycoconjugates and lipids. The observed lowered calcification under OA can be attributed to impaired signal-transduction and ion-transport. The haplont utilizes distinct genes and metabolic pathways, reflecting the stage-specific usage of certain portions of the genome. With respect to functionality and energy-dependence, however, the transcriptomic OA-responses resemble those of the diplont. In both life-cycle stages, OA affects the cellular redox-state as a master regulator and thereby causes a metabolic shift from oxidative towards reductive pathways, which involves a reconstellation of carbon flux networks within and across compartments. Whereas signal transduction and ion-homeostasis appear equally OA-sensitive under both light intensities, the effects on carbon metabolism and light physiology are clearly modulated by light availability. These interactive effects can be attributed

This paper extends the concept of therapeutic landscapes by investigating how green and blue spaces affect older adult health and wellbeing. We draw on interview data from participants aged 65-86 years old who described their everyday experiences with green and especially blue spaces across Metro Vancouver, Canada. Landscapes embedded with therapeutic qualities included parks, gardens, street greenery, lakes, and the ocean. Interactions with these spaces influenced participants' perceived physical, mental, and social health. Issues of safety, accessibility, and personal perception complicated this relationship. Overall, the findings indicate that nature plays a nuanced and influential role in the everyday lives of older adults. Better understanding how older adults experience health and landscape is critical towards developing everyday contact with nature that can improve quality of life for ageing populations.

Previously, we found that mutation of glutamine to proline in the endoproteolytic cleavage signal of the PERV-C envelope (RQKK to RPKK) resulted in non-infectious vectors. Here, we show that RPKK results in a non-infectious vector when placed in not only a PERV envelope, but also the envelope of a related gammaretrovirus, FeLV-B. The amino acid substitutions do not prevent envelope precursor cleavage, viral core and genome assembly, or receptor binding. Rather, the mutations result in the formation of hyperglycosylated glycoprotein and a reduction in the reverse transcribed minus strand synthesis and undetectable 2-LTR circular DNA in cells exposed to vectors with these mutated envelopes. Our findings suggest novel functions associated with the cleavage signal sequence that may affect trafficking through the glycosylation machinery of the cell. Further, the glycosylation status of the envelope appears to impact post-binding events of the viral life cycle, either membrane fusion, internalization, or reverse transcription. - Highlights: • Env cleavage signal impacts infectivity of gammaretroviruses. • Non-infectious mutants have hyper-glycosylated envelope that bind target cells. • Non-infectious mutants have defects in the formation of the double-stranded DNA. • Env cleavage motif has functions beyond cleavage of the env precursor.

Physical, social, and attitudinal environment may affect the quality of life (QoL) of children and adolescents with cerebral palsy (CP). Participants in this study included parents of 206 children and adolescents with CP (55.8% males) aged 8-18 years (M=11.96, SD=3). Distribution according to the Gross Motor Function Classification System (GMFCS) was 24.3% level I, 18% level II, 18% level III, 12.6% level IV, and 27.2 level V. Environmental barriers were assessed with the Spanish version of the European Child Environment Questionnaire (ECEQ), and QoL was assessed with the KIDSCREEN parents' version. The results of the correlation analysis revealed that GMFCS level, IQ, and type of schooling are significantly correlated with QoL. Barriers were also associated with QoL. A series of hierarchical regression analyses indicated that, after controlling for the effect of child and parent's variables, barriers at home and at school significantly contribute to QoL. These findings underscore the importance of providing interventions to produce environmental changes that contribute to the improvement of QoL.

To determine the clinical impact of endogenous subclinical hyperthyroidism, specific symptoms and signs of thyroid hormone excess and quality of life were assessed in 23 patients (3 males and 20 females; mean age, 43 +/- 9 yr) and 23 age-, sex-, and lifestyle-matched normal subjects by using the Symptoms Rating Scale and the Short Form 36 Health Survey questionnaires. Because the heart is one of the main target organs of the thyroid hormone, cardiac morphology and function were also investigated by means of standard 12-lead electrocardiogram (ECG), 24-h Holter ECG, and complete Doppler echocardiography. Stable endogenous subclinical hyperthyroidism had been diagnosed in all patients at least 6 months before the study (TSH, 0.15 +/- 0.1 mU/L; free T(3), 6.9 +/- 1.1, pmol/L; free T(4), 17.2 +/- 2.3, pmol/L). Fifteen patients were affected by multinodular goiter, and eight patients by autonomously functioning thyroid nodule. The mean Symptoms Rating Scale score (9. 8 +/- 5.5 vs. 4.3 +/- 2.2, P: < 0.001) and both the mental (36.1 +/- 9.5 vs. 50.0 +/- 8.5, P: < 0.001) and physical (42.6 +/- 8.0 vs. 55. 6 +/- 4.1, P: < 0.001) component scores of Short Form 36 Health Survey documented a significant prevalence of specific symptoms and signs of thyroid hormone excess and notable impairment of quality of life in patients. Holter ECG showed a higher prevalence of atrial premature beats in endogenous subclinical hyperthyroid patients than in the controls, but the difference was not statistically significant, although the average heart rate was significantly increased in the patients (P: < 0.001). An increase of left ventricular mass (162 +/- 24 vs. 132 +/- 22 g, P: < 0.001) due to the increase of septal (P: = 0.025) and posterior wall (P: = 0.004) thickness was observed in patients. Systolic function was enhanced in patients as shown by the significant increase of both fractional shortening (P: = 0.005) and mean velocity of heart rate-adjusted circumferential fiber shortening

This article is a joint exploration of what decolonization looks like in everyday interactions within our partnerships, families, and friendships on unceded Coast Salish territories. Stories from the authors--two cisgender queer women, one of whom is Indigenous and one of whom is a White settler--highlight intimate practices of allyship and decolonization that are often made invisible when activism is seen as only taking place in "public" spaces such as community coalitions. The tensions and possibilities within these intimate geographies of allyship comprise a decolonial queer praxis that is materialized in the spatial relations of our homes and families.

Background Previous studies have shown the effects of childhood abuse, life events, and temperaments on well-being (positive affect) and ill-being (negative affect). We hypothesized that childhood abuse, affective temperaments, and adult life events interact with one another and influence positive and negative affects in the general adult population and tested this hypothesis using structural equation modeling. Methods A total of 415 participants from the general, nonclinical adult population were studied using the following self-administered questionnaires: the Subjective Well-Being Inventory (SUBI); Life Experiences Survey (LES); Temperament Evaluation of the Memphis, Pisa, Paris, and San Diego Auto-questionnaire (TEMPS-A); and the Child Abuse and Trauma Scale (CATS). The data were analyzed with single and multiple regression analyses and structural equation modeling (Mplus). Results Childhood abuse indirectly predicted the worsening of positive and negative affects through cyclothymic, anxious, and irritable temperaments as measured by the TEMPS-A in the structural equation model. The cyclothymic, anxious, and irritable temperaments directly worsened the positive and negative affects and the negative appraisal of life events that occurred during the past year, while the hyperthymic temperament had the opposite effects. Limitations The subjects of this study were nonclinical volunteers. The findings might not be generalizable to psychiatric patients. Conclusion This study demonstrated that childhood abuse, particularly neglect, indirectly worsened the well-being of individuals through cyclothymic, anxious, and irritable affective temperaments. An important “mediator” role of affective temperaments in the effect of childhood abuse on well-being was suggested. PMID:27110116

Early accounts of problem solving focused on the ways people represent information directly related to target problems and possible solutions. Subsequent theory and research point to the role of peripheral influences such as heuristics and bodily states. We discuss how metaphor and analogy similarly influence stages of everyday problem solving: Both processes mentally map features of a target problem onto the structure of a relatively more familiar concept. When individuals apply this structure, they use a well-known concept as a framework for reasoning about real world problems and candidate solutions. Early studies found that analogy use helped people gain insight into novel problems. More recent research on metaphor goes further to show that activating mappings has subtle, sometimes surprising effects on judgment and reasoning in everyday problem solving. These findings highlight situations in which mappings can help or hinder efforts to solve problems.

Nutritional status is an independent prognostic factor in immunoglobulin light-chain amyloidosis (AL), but its influence on quality of life (QoL) is unknown. The aim of this cross-sectional study was to investigate the association between nutritional status and QoL in AL patients at diagnosis. One hundred and fifty consecutive patients with biopsy-proven AL were assessed for nutritional status by anthropometry [body mass index, unintentional weight loss (WL) in the previous 6 months and mid-arm muscle circumference (MAMC)], biochemistry (serum prealbumin), and semiquantitative food intake at referral. QoL was assessed by the Medical Outcomes Study 36-item Short Form General Health Survey. The composite physical component summary (PCS) and the mental component summary (MCS) for AL outpatients were 36.2 ± 10.1 and 44.9 ± 11.3, respectively (p < 0.001 for both vs the population norms of 50). In multivariate linear regression models adjusted for gender, age, Eastern Cooperative Oncology Group performance status, the number of organs involved, the severity of cardiac damage, C-reactive protein, energy intake, and WL, PCS was significantly lower for serum prealbumin <200 mg/L and MAMC <10th percentile (adjusted difference 3.8, 95% CI 0.18-7.5, p = 0.040 and 5.3, 95% CI 2.0-8.7, p = 0.002, respectively). MCS was decreased by 0.47 (95% CI 0.18-0.75, p = 0.002) for each kilogram of body weight lost in the previous 6 months. Nutritional status independently affects QoL in AL patients since diagnosis. Nutritional evaluation should be integral part of the clinical assessment of AL patients. Nutritional support intervention trials are warranted in such patients' population.

We tested the hypothesis that exposure of leopard frogs ( Rana pipiens) to agricultural pesticides can affect the infection dynamics of a common parasite of ranid frogs, the lungworm Rhabdias ranae. After a 21-day exposure to sublethal concentrations of a pesticide mixture composed of atrazine, metribuzin, aldicarb, endosulfan, lindane and dieldrin, or to control solutions (water, dimethyl sulfoxide), parasite-free juvenile frogs were challenged with 30 infective larvae of R. ranae. Approximately 75% of the larvae penetrated the skin and survived in both exposed and control animals, suggesting that pesticides did not influence host recognition or penetration components of the transmission process. Rather, we found that the migration of R. ranae was significantly accelerated in hosts exposed to the highest concentrations of pesticides, leading to the establishment of twice as many adult worms in the lungs of frogs 21 days post-infection. Pesticide treatment did not influence the growth of lungworms but our results indicate that they matured and reproduced earlier in pesticide-exposed frogs compared to control animals. Such alterations in life history characteristics that enhance parasite transmission may lead to an increase in virulence. Supporting evidence shows that certain components of the frog immune response were significantly suppressed after exposure to the pesticide mixture. This suggests that the immune system of anurans exerts a control over lungworm migration and maturation and that agricultural contaminants can interfere with these control mechanisms. Our results also contribute to the ongoing debate regarding the role that anthropogenic factors could play in the perplexing disease-related die-offs of amphibians observed in several parts of the world.

This study aimed to determine whether psychological factors affect health-related quality of life (HRQL) and recovery of knee function in total knee replacement (TKR) patients. A total of 119 TKR patients (male: 38; female: 81) completed the Beck Anxiety Inventory (BAI), Beck Depression Inventory (BDI), State Trait Anxiety Inventory (STAI), Eysenck Personality Questionnaire-revised (EPQR-S), Knee Society Score (KSS), and HRQL (SF-36). At 1 and 6 months after surgery, anxiety, depression, and KSS scores in TKR patients were significantly better compared with those preoperatively (P<0.05). SF-36 scores at the sixth month after surgery were significantly improved compared with preoperative scores (P<0.001). Preoperative Physical Component Summary Scale (PCS) and Mental Component Summary Scale (MCS) scores were negatively associated with extraversion (E score) (B=-0.986 and -0.967, respectively, both P<0.05). Postoperative PCS and State Anxiety Inventory (SAI) scores were negatively associated with neuroticism (N score; B=-0.137 and -0.991, respectively, both P<0.05). Postoperative MCS, SAI, Trait Anxiety Inventory (TAI), and BAI scores were also negatively associated with the N score (B=-0.367, -0.107, -0.281, and -0.851, respectively, all P<0.05). The KSS function score at the sixth month after surgery was negatively associated with TAI and N scores (B=-0.315 and -0.532, respectively, both P<0.05), but positively associated with the E score (B=0.215, P<0.05). The postoperative KSS joint score was positively associated with postoperative PCS (B=0.356, P<0.05). In conclusion, for TKR patients, the scores used for evaluating recovery of knee function and HRQL after 6 months are inversely associated with the presence of negative emotions.

This paper makes a contribution to an emerging debate on dementia and citizenship through a focus on the everyday experiences of women living with dementia and in receipt of care. In particular, a link is drawn between hairdressing and citizenship in the context of dementia care. Informed by a wider debate over the importance of an emplaced, embodied and performative approach to citizenship, the authors highlight the way that intersecting forms of resistance unfold in the salon. The Hair and Care project, as the name implies, focused upon hair care and styling in the context of a wider consideration of appearance and how it is managed and what it means for people living with dementia. With a focus upon the routine, mundane and thereby often unproblematised aspects of everyday life in/with care, the discussion draws together two key ideas concerned with the interplay of power and resistance: Essed's (1991) theory of 'everyday discrimination' and Scott's (1985) notion of 'everyday resistance'. The findings illuminate the creative and collective forms of agency exercised by older women living with dementia, in the context of their relationships with one another and with the hairdressers whose services and support inspire their loyalty and patronage. Findings from the study point to the link between (inter-)personal practices of appearance management and a wider set of social conditions that are manifest in the on-going struggle over time, space and bodies in dementia care.

Previous research has shown that major life events can have short- and long-term effects on subjective well-being (SWB). The present meta-analysis examines (a) whether life events have different effects on cognitive and affective well-being and (b) how the rate of adaptation varies across different life events. Longitudinal data from 188 publications (313 samples, N = 65,911) were integrated to describe the reaction and adaptation to four family events (marriage, divorce, bereavement, child birth) and four work events (unemployment, reemployment, retirement, relocation/migration). The findings show that life events have very different effects on affective and cognitive well-being, and that for most events the effects of life events on cognitive well-being are stronger and more consistent across samples. Different life events differ in their effects on SWB, but these effects are not a function of the alleged desirability of events. The results are discussed with respect to their theoretical implications, and recommendations for future studies on adaptation are given. PMID:22059843

We measured utility curves for the hypothetical monetary costs as a function of time engaged in three everyday physical activities: walking, standing, and sitting. We found that activities requiring more physical exertion resulted in steeper discount curves, i.e., perceived cost as a function of time. We also examined the effects of gain vs. loss framing (whether the activity brought additional rewards or prevented losses) as well as the effects of the individual factors of gender, income, and BMI. Steeper discount curves were associated with higher income (annual household ≥ median of $45,000) and gain framing (which indicates loss aversion). There were interactions between gender and frame, and also income and frame: Females and higher income participants showed loss aversion whereas males and lower income participants were not affected by framing. Males showed less discounting in gain frames relative to females, whereas females showed less discounting in loss frames relative to males. In gain frames, higher income participants discounted more but in loss frames there was no effect of income. We also found individual tendencies for discounting across activities: if an individual exhibited steeper discounting for one activity, they were also more likely to exhibit steeper discounting for the other activities. These results have implications for designers of interventions to encourage non-exercise physical activities, suggesting that loss-framed incentives are more effective for women and those with middle class (or greater) incomes. Furthermore loss framed incentives have more uniform impact across income brackets because people discount loss frames similarly regardless of income whereas those with middle-class incomes are not as motivated by gain frames. Our results also demonstrate a general method for examining the costs of effort associated with everyday activities.

Purpose Cognitive enhancements are associated with sport training. We extended the sport-cognition literature by using a realistic street crossing task to examine the multitasking and processing speed abilities of collegiate athletes and nonathletes. Methods Pedestrians navigated trafficked roads by walking on a treadmill in a virtual world, a challenge that requires the quick and simultaneous processing of multiple streams of information. Results Athletes had higher street crossing success rates than nonathletes, as reflected by fewer collisions with moving vehicles. Athletes also showed faster processing speed on a computer-based test of simple reaction time, and shorter reaction times were associated with higher street crossing success rates. Conclusions The results suggest that participation in athletics relates to superior street crossing multitasking abilities and that athlete and nonathlete differences in processing speed may underlie this difference. We suggest that cognitive skills trained in sport may transfer to performance on everyday fast-paced multitasking abilities. PMID:21407125

Aim. To explore individual quality of life in patients with head and neck cancer from diagnosis up to 3 months after termination of radiotherapy. Research questions: 1) Which areas in life are important to quality of life, and which are influenced by the disease and by having oral or enteral nutrition; and 2) Which areas in life are influenced by having a nasogastric feeding tube (NGT) or a percutaneous endoscopic gastrostomy (PEG) tube? Material and methods. Data were collected in 36 patients. Semi-structured interviews were conducted using an extended version of the Schedule for the Evaluation of Individual Quality of Life (SEIQoL) and analysed with content analysis. Results. Negative and positive experiences of quality of life in general were about relation to family, own health, and leisure activities. Negative impacts on physical, psychological, existential and social problems, but also positive experiences are described by the patients related to the disease. More than half expressed eating-related problems. Enteral nutrition entailed negative and positive experiences, and no greater variations were described by the patients with NGT or PEG tube. Overall, there were interindividual variations. Conclusions. The patients’ perception of general or disease-related quality of life was not affected by whether they had enteral nutrition or not. From the patients’ perspective neither of the two feeding tubes (NGT or PEG) was clearly in favour. We suggest that more studies are needed on how the choice of enteral feeding tube can be evidence-based, and incorporating the patients’ perspective. PMID:26482657

The research reported here investigated the everyday and scientific repertoires of children involved in semi-structured, Piagetian interviews carried out to check their understanding of dynamic astronomical concepts like daytime and night-time. It focused on the switching taking place between embedded and disembedded thinking; on the imagery which subjects referred to in their verbal dialogue and their descriptions of drawings and play-dough models of the Earth, Sun and Moon; and it examined the prevalence and character of animism and figurative speech in children's thinking. Five hundred and thirty-nine children (aged 3-18) from Wairarapa in New Zealand (171 boys and 185 girls) and Changchun in China (99 boys and 84 girls) took part in the study. Modified ordinal scales for the relevant concept categories were used to classify children's responses and data from each age group (with numbers balanced as closely as practicable by culture and gender) analysed with Kolmogorov-Smirnov two-sample tests (at an alpha level of 0.05). Although, in general, there was consistency of dynamic concepts within and across media and their associated modalities in keeping with the theory of conceptual coherence (see Blown and Bryce 2010; Bryce and Blown 2016), there were several cases of inter-modal and intra-modal switching in both cultures. Qualitative data from the interview protocols revealed how children switch between everyday and scientific language (in both directions) and use imagery in response to questioning. The research indicates that children's grasp of scientific ideas in this field may ordinarily be under-estimated if one only goes by formal scientific expression and vocabulary.

Children's everyday ideas form critical foundations for science learning yet little research has been conducted to understand and legitimize these ideas, particularly from an international perspective. This paper explores children's everyday ideas about the environment across the US, Singapore and China to understand what they reveal about children's relationship to the environment and discuss its implications for science teaching and learning. A social constructivist lens guides research, and a visual methodology is used to frame children's realities. Participants' ages range from elementary to middle school, and a total of 210 children comprized mainly of Asians and Asian Americans were sampled from urban settings. Drawings are used to elicit children's everyday ideas and analyzed inductively using open coding and categorizing of data. Several categories support existing literature about how children view the environment; however, novel categories such as affect also emerged and lend new insight into the role that language, socio-cultural norms and perhaps ethnicity play in shaping children's everyday ideas. The findings imply the need for (a) a change in the role of science teachers from knowledge providers to social developers, (b) a science curriculum that is specific to learners' experiences in different socio-cultural settings, and (c) a shift away from inter-country comparisons using international science test scores.

To date, few studies have investigated the eye movement patterns of individuals with glaucoma while they undertake everyday tasks in real-world settings. While some of these studies have reported possible compensatory gaze patterns in those with glaucoma who demonstrated good task performance despite their visual field loss, little is known about the complex interaction between field loss and visual scanning strategies and the impact on task performance and, consequently, on quality of life. We review existing approaches that have quantified the effect of glaucomatous visual field defects on the ability to undertake everyday activities through the use of eye movement analysis. Furthermore, we discuss current developments in eye-tracking technology and the potential for combining eye-tracking with virtual reality and advanced analytical approaches. Recent technological developments suggest that systems based on eye-tracking have the potential to assist individuals with glaucomatous loss to maintain or even improve their performance on everyday tasks and hence enhance their long-term quality of life. We discuss novel approaches for studying the visual search behavior of individuals with glaucoma that have the potential to assist individuals with glaucoma, through the use of personalized programs that take into consideration the individual characteristics of their remaining visual field and visual search behavior.

The combined use of antimicrobial compounds and modified atmosphere packaging (MAP) on shelf life of reduced pork back-fat content sausages was investigated in this study. First, a pre-screening of different antimicrobial compounds and MAP was addressed. In particular, the consumer test was used as a tool to select the most pleasant antimicrobial compounds, whereas both sausage color and cell load of main spoilage microorganisms were used to choose optimal MAP. Afterwards, antimicrobial compounds (lemon alkott and thymol) and MAP (MAP1: 20% CO(2), 5% O(2), 75% N(2)) that had shown the best performance were used to run the shelf life tests. In order to assess the influence of the variables described beforehand on the shelf life of investigated sausages, the sensorial and microbiological (mesophilic and psychrotrophic bacteria, Enterobacteriaceae, Pseudomonas spp., lactic acid bacteria and coccus-shaped lactic acid bacteria) quality was monitored during storage. Results recorded in this study suggested that Pseudomonas spp. were responsible for sausage unacceptability in all samples, except for thymol and thymol-MAP samples. For these samples, the sensorial quality was the limiting factor while the microbial growth did not limit the shelf life. In particular, for thymol and thymol-MAP samples a shelf life value of more than 5 days with respect to the other samples (2 days) was obtained.

This qualitative study discusses post separation stalking and its implications in children's everyday lives. Based on narratives of 13 Finnish children and 20 women, the research fills a gap in the knowledge regarding the psychosocial, emotional, and physical impacts of stalking on children when their mothers are stalked by a former partner. It identifies four forms of impact: (a) an atmosphere of fear and feelings of insecurity; (b) disguised acts of stalking and the father's performance of care, love, and longing; (c) exploitation of children in stalking; and (d) physical abuse, acts of violence, and threats of death. The findings indicate that stalking severely constrains children's everyday lives and strengthens, yet often distorts, the mother-child bond. The study concludes that in cases where mothers are stalked, professionals in the social and health services, law enforcement, and criminal justice should view the children, too, as victims and construct supportive social relationships for women and children facing threatening life situations.

Individuals attuned to affective signals from the environment may possess an advantage in the emotion-regulation realm. In two studies (total n = 151), individual differences in affective perception accuracy were assessed in an objective, performance-based manner. Subsequently, the same individuals completed daily diary protocols in which daily stressor levels were reported as well as problematic states shown to be stress-reactive in previous studies. In both studies, individual differences in affect perception accuracy interacted with daily stressor levels to predict the problematic outcomes. Daily stressors precipitated problematic reactions--whether depressive feelings (study 1) or somatic symptoms (study 2)--at low levels of affect perception accuracy, but did not do so at high levels of affect perception accuracy. The findings support a regulatory view of such perceptual abilities. Implications for understanding emotion regulation processes, emotional intelligence, and individual differences in reactivity are discussed.

Lignocellulosic ethanol has potential for lower life cycle greenhouse gas emissions compared to gasoline and conventional grain-based ethanol. Ethanol production 'pathways' need to meet economic and environmental goals. Numerous life cycle assessments of lignocellulosic ethanol have been published over the last 15 years, but gaps remain in understanding life cycle performance due to insufficient data, and model and methodological issues. We highlight key aspects of these issues, drawing on literature and a case study of corn stover ethanol. Challenges include the complexity of feedstock/ecosystems and market-mediated aspects and the short history of commercial lignocellulosic ethanol facilities, which collectively have led to uncertainty in GHG emissions estimates, and to debates on LCA methods and the role of uncertainty in decision making.

Self-esteem has been demonstrated to predict health and well-being in a number of samples and domains using retrospective reports, but little is known about the effect of self-esteem in daily life. A community sample with asthma (n = 97) or rheumatoid arthritis (n = 31) completed a self-esteem measure and collected Ecological Momentary Assessment (EMA) data 5x/day for one week using a palmtop computer. Low self-esteem predicted more negative affect, less positive affect, greater stress severity, and greater symptom severity in daily life. Naturalistic exploration of mechanisms relating self-esteem to physiological and/or psychological components in illness may clarify causal relationships and inform theoretical models of self-care, well-being, and disease management.
This paper examines the parapraxes made by, to or about Jewish-identified individuals discussed by Freud in Psychopathology of everyday life. Each of these errors and slips is occasioned by what he terms a 'mesalliance' between a Jew and a Gentile. Such incidents of distorted language betray unresolved ambivalences and unformulated anxieties endemic to Jewish-Gentile interaction in Freud's Vienna. First, the disturbed relationships between German-speaking Gentiles and their threatening Doppelganger, the Jews, are analyzed by means of Freud's analysis of the 'uncanny' and an examination of the particular restrictions placed upon the 'officially' emancipated Jews in the Habsburg Empire, especially with regard to intermarriage. Then, the paper turns to Freud's discussions of explicitly Jewish-identified individuals and their limitation to illustrating parapraxes associated with what should be the most pleasurable and intimate relationships between Jew and Gentile, namely sexual and connubial relations. His focus upon this conflicted conjunction diagnosed the intrinsically problematic character of Jew-Gentile interaction in his Vienna.

Moral emotions are typically elicited in everyday social interactions and regulate social behavior. Previous research in the field of attribution theory identified ought (the moral standard of a given situation or intended goal), goal-attainment (a goal can be attained vs. not attained) and effort (high vs. low effort expenditure) as cognitive antecedents of moral emotions. In contrast to earlier studies, mainly relying on thought experiments, we investigated autobiographical recollections of N = 312 participants by means of an online study. We analyzed a diverse range of moral emotions, i.e., admiration, anger, contempt, indignation, pride, respect, schadenfreude, and sympathy, by using a mixed-method approach. Qualitative and quantitative methods clearly corroborate the important role of ought, goal-attainment, and effort as eliciting conditions of moral emotions. Furthermore, we built categorical systems based on our participants’ descriptions of real-life situations, allowing for more fine-grained distinctions between seemingly similar moral emotions. We thus identify additional prerequisites explaining more subtle differences between moral emotion clusters as they emerge from our analyses (i.e., cluster 1: admiration, pride, and respect; cluster 2: anger, contempt, and indignation; cluster 3: schadenfreude and sympathy). Results are discussed in the light of attributional theories of moral emotions, and implications for future research are derived. PMID:27977699

Academic buoyancy is developed as a construct reflecting everyday academic resilience within a positive psychology context and is defined as students' ability to successfully deal with academic setbacks and challenges that are typical of the ordinary course of school life (e.g., poor grades, competing deadlines, exam pressure, difficult schoolwork). Data were collected from 598 students in Years 8 and 10 at five Australian high schools. Half-way through the school year and then again at the end of the year, students were asked to rate their academic buoyancy as well as a set of hypothesized predictors (self-efficacy, control, academic engagement, anxiety, teacher-student relationship) in the area of mathematics. Multilevel modeling found that the bulk of variance in academic buoyancy was explained at the student level. Confirmatory factor analysis and structural equation modeling showed that (a) Time 1 anxiety (negatively), self-efficacy, and academic engagement significantly predict Time 1 academic buoyancy; (b) Time 2 anxiety (negatively), self-efficacy, academic engagement, and teacher-student relationships explain variance in Time 2 academic buoyancy over and above that explained by academic buoyancy at Time 1; and (c) of the significant predictors, anxiety explains the bulk of variance in academic buoyancy.

Seed morph, abiotic conditions and time of germination can affect plant fitness, but few studies have tested their combined effects on plasticity of plant life history traits. Thus, we tested the hypothesis that seed morph, germination season and watering regime influence phenotypic expression of post-germination life history traits in the diaspore-heteromorphic cold desert winter annual/spring ephemeral Diptychocarpus strictus. The two seed morphs were sown in watered and non-watered plots in late summer, and plants derived from them were watered or not-watered throughout the study. Seed morph did not affect phenology, growth and morphology, survival, dry mass accumulation and allocation or silique and seed production. Seeds in watered plots germinated in autumn (AW) and spring (SW) but only in spring for non-watered plots (SNW). A high percentage of AW, SW and SNW plants survived and reproduced, but flowering date and flowering period of autumn- vs. spring-germinated plants differed. Dry mass also differed with germination season/watering regime (AW > SW > SNW). Number of siliques and seeds increased with plant size (AW > SW > SNW), whereas percent dry mass allocated to reproduction was higher in small plants: SNW > SW > AW. Thus, although seed morph did not affect the expression of life history traits, germination season and watering regime significantly affected phenology, plant size and accumulation and allocation of biomass to reproduction. Flexibility throughout the life cycle of D. strictus is an adaptation to the variation in timing and amount of rainfall in its cold desert habitat.

Most emergency care facilities in tropical areas are inefficient, underequipped, and quickly overwhelmed by the ever-growing attendance. As a result, mortality is higher than in developed countries. To speak in terms of natural selection would be tantamount to a fatalistic admission of powerlessness to deal with the situation. In Africa, the gross imbalance between supply and demand makes it necessary to make hard choices in order to make the most effective use of available staff and equipment. The objective of medical triage is to allocate scarce facilities to those patients with the greatest chance of survival. However it is difficult to define precise rules for making such choices since they are strongly dependent on available resources, type of pathology, and level of medical skill. Prognostic indicators are ill-suited to emergency situation since they require not only clinical data but also and above all, in most cases, laboratory data which is not always available or justifiable. Experience is probably the best guarantee for reliable triage, which is philosophically difficult to accept but often unavoidable in everyday practice.

The authors developed a 12-category, 116-item critical incident questionnaire of spatial behavior. The authors administered the Everyday Spatial Behavioral Questionnaire (ESBQ) to volunteer undergraduates (114 women, and 31 men) and tests of spatial ability to establish both the reliability and construct validity of the instrument. The authors found that Cronbach's alpha across the subscale scores was .92, and that 8 of the 12 subscales had alphas of .70 or greater. The authors found validity of the ESBQ through canonical correlation analysis. Specifically, spatial tests, gender, and age variables, jointly with the ESBQ subscales, identified 2 apparent continua of spatial skills. The authors labeled the first continuum movement through space (from moving a vehicle at one end of the continuum, to moving one's own body through space at the other end of the continuum). The authors labeled the second identified continuum drawing/perceiving perspective/path finding, and it appeared to represent a continuum of 3-dimensional visualization or redirection. Another suggested label was dimensional discernment. Thus, the ESBQ is a first step toward identifying new ways to think about and quantify people's spatial experience.

People readily make personality attributions to images of strangers' faces. Here we investigated the basis of these personality attributions as made to everyday, naturalistic face images. In a first study, we used 1000 highly varying “ambient image” face photographs to test the correspondence between personality judgments of the Big Five and dimensions known to underlie a range of facial first impressions: approachability, dominance, and youthful-attractiveness. Interestingly, the facial Big Five judgments were found to separate to some extent: judgments of openness, extraversion, emotional stability, and agreeableness were mainly linked to facial first impressions of approachability, whereas conscientiousness judgments involved a combination of approachability and dominance. In a second study we used average face images to investigate which main cues are used by perceivers to make impressions of the Big Five, by extracting consistent cues to impressions from the large variation in the original images. When forming impressions of strangers from highly varying, naturalistic face photographs, perceivers mainly seem to rely on broad facial cues to approachability, such as smiling. PMID:26579008

Previous research has shown that the disease load experienced during the birth year, measured as the infant mortality rate, had a significant influence on old-age mortality in nineteenth-century rural Sweden. We know that children born in years with very high rates of infant mortality, due to outbreaks of smallpox or whooping cough, and who still survived to adulthood and married, faced a life length several years shorter than others. We do not know, however, whether this is a direct effect, caused by permanent physical damage leading to fatal outcomes later in life, or an indirect effect, via its influence on accumulation of wealth and obtained socio-economic status. The Scanian Demographic Database, with information on five rural parishes in southern Sweden between 1813 and 1894, contains the data needed to distinguish between the two mechanisms. First, the effects of conditions in childhood on obtained socio-economic status as an adult are analyzed, then the effects of both early-life conditions and socio-economic status at various stages of life on old-age mortality. By including random effects, we take into account possible dependencies in the data due to kinship and marriage. We find that a high disease load during the first year of life had a strong negative impact on a person's ability to acquire wealth, never before shown for a historical setting. This means that it is indeed possible that the effects of disease load in the first year of life indirectly affect mortality in old age through obtained socio-economic status. We find, however, no effects of obtained socio-economic status on old-age mortality. While the result is interesting per se, constituting a debatable issue, it means that the argument that early-life conditions indirectly affect old-age mortality is not supported. Instead, we find support for the conclusion that the effect of the disease load in early-life is direct or, in other words, that physiological damage from severe infections at the

Two alternative models of impaired cognitive and affective processing that may underlie reduced social quality of life (SQoL) of persons with schizophrenia, were examined. According to the parallel process model, impaired cognitive empathy and affective empathy make relatively independent contributions to the symptoms of schizophrenia and to the consequent reduction in SQoL. According to the integrative mediation model, the symptoms of schizophrenia and the reduction in SQoL associated with these symptoms are the products of a process by which impairments of cognitive empathy are contingent on impairments of affective empathy. 90 persons with schizophrenia were assessed for SQoL, symptoms and cognitive and affective empathy. Results support the integrative mediation model only for cognitive empathy and negative psychiatric symptoms. Only the negative links between cognitive empathy and negative symptoms served to mediate the positive relation between affective empathy and SQoL. Positive symptoms had a limited negative impact on SQoL and did not play a role in the paths that linked affective empathy to SQoL. Age had a statistically significant and negative indirect relationship to SQoL. Results are consistent with recent approach that distinguish between cognitive and affective empathy and specify how these two processes are integrated.

Objective Stressful family environments early in life have negative effects on physical health. However, less is known about the health effects of positive aspects of families. We examined the associations between maternal responsiveness and immune markers among youth with asthma and identified youth expressions of positive affect as a potential mechanism of these associations. Methods Forty-three youths with asthma (26 males; aged 10-17) wore the Electronically Activated Recorder (EAR) for four days to assess maternal responsiveness and youth expressions of affect from audio-recordings of daily life. Trained coders rated EAR sound files for expressions of maternal responsiveness and affect displayed by the youth. Peripheral blood mononuclear cells were isolated, cultured, and assayed to determine stimulated levels of interleukin(IL)-5, IL-13, and interferon(IFN)- γ. Results Greater maternal responsiveness was associated with decreased stimulated production of IL-5 (r = −.38, p = .012) and IL-13 (r = −.33, p = .031). Greater total positive affect in youth was linked with decreased stimulated production of IL-5 (r = −.46, p = .002) and IL-13 (r = −.37, p = .014). Total negative affect among youth was unrelated to immune responses. There was a significant indirect effect of maternal responsiveness via positive affect in youth on lower levels of IL-5 (95% CI = −3.41, −.03) and IL-13 (95% CI = −2.34, −.01) when adjusting for caregiver-youth conflict and negative affect among youth. Conclusions These results indicate the importance of positive family interactions for youth and provide preliminary evidence for a mechanism through which parenting can influence immune responses in youths with asthma.

A history of childhood trauma is associated with increased risk for psychopathology and interpersonal difficulties in adulthood and, for those who have children, impairments in parenting and increased risk of negative outcomes in offspring. Physiological and behavioral mechanisms are poorly understood. In the current study, maternal history of childhood trauma was hypothesized to predict differences in maternal affect and HPA axis functioning. Mother-infant dyads (N = 255) were assessed at 6 months postpartum. Mothers were videotaped during a 3-min naturalistic interaction, and their behavior was coded for positive, neutral, and negative affect. Maternal salivary cortisol was measured six times across the study visit, which also included an infant stressor paradigm. Results showed that childhood trauma history predicted increased neutral affect and decreased mean cortisol in the mothers and that cortisol mediated the association between trauma history and maternal affect. Maternal depression was not associated with affective measures or cortisol. Results suggest that early childhood trauma may disrupt the development of the HPA axis, which in turn impairs affective expression during mother-infant interactions in postpartum women. Interventions aimed at treating psychiatric illness in postpartum women may benefit from specific components to assess and treat trauma-related symptoms and prevent secondary effects on parenting.

Vitiligo has a major effect on sexual health because of the disfiguring skin lesions affecting self-image and self-esteem. However, this topic has not explored. This article aimed to assess the effect of vitiligo on genital self-image, sexual function, and quality of life in female patients. This cross-sectional study included 50 sexually active women with vitiligo and 25 women without vitiligo. All participants subjected to full history taking and examination. Extent of vitiligo was assessed with the Vitiligo Area Scoring Index score, sexual function with the Female Sexual Function Index, genital self-image with Female Genital Self-Image Score and quality of life with the Dermatology Life Quality Index questionnaires. The main outcome measures were correlation between Vitiligo Area Scoring Index, Female Genital Self-Image Score, Female Sexual Function Index, and Dermatology Life Quality Index domains was determined using t test and Pearson correlation. This study revealed a negative correlation between the Vitiligo Area Scoring Index score and sexual satisfaction. Vitiligo Area Scoring Index and Dermatology Life Quality Index score was significantly correlated with Arabic Version of the Female Genital Self-Image Score alone and with Arabic Version of the Female Sexual Functioning Index alone and with both the Arabic Version of the Female Genital Self-Image Score and the Arabic Version of the Female Sexual Functioning Index (p <.05). Sexual and psychological assessment of patients with vitiligo is imperative to improve outcomes and increase patients' compliance with treatment.

Light pollution or artificial light at night (ALAN) is increasingly recognised to be an important anthropogenic environmental pressure on wildlife, affecting animal behaviour and physiology. Early life experiences are extremely important for the development, physiological status and health of organisms, and as such, early exposure to artificial light may have detrimental consequences for organism fitness. We experimentally manipulated the light environment of free-living great tit nestlings (Parus major), an important model species in evolutionary and environmental research. Haptoglobin (Hp) and nitric oxide (NOx), as important indicators of immunity, health, and physiological condition, were quantified in nestlings at baseline (13 days after hatching) and after a two night exposure to ALAN. We found that ALAN increased Hp and decreased NOx. ALAN may increase stress and oxidative stress and reduce melatonin which could subsequently lead to increased Hp and decreased NOx. Haptoglobin is part of the immune response and mounting an immune response is costly in energy and resources and, trade-offs are likely to occur with other energetically demanding tasks, such as survival or reproduction. Acute inhibition of NOx may have a cascading effect as it also affects other physiological aspects and may negatively affect immunocompetence. The consequences of the observed effects on Hp and NOx remain to be examined. Our study provides experimental field evidence that ALAN affects nestlings' physiology during development and early life exposure to ALAN could therefore have long lasting effects throughout adulthood.

Objective Functional gastrointestinal disorders (FGID) have been shown to be associated with both comorbid mood disorders and traumatic events such as abuse earlier in life. In a longitudinal study, we tested a model that hypothesized: (i) childhood abuse was associated with subsequent mood disorder and pain or interference in life by bowel symptoms both directly and indirectly via neurotic personality; and (ii) an ongoing cycle of mood disorder impacts on bowel symptoms. Design Subjects from the general population classified as irritable bowel syndrome and/or functional dyspepsia (IBS/FD, n = 207) or free of FGID (n = 100) were prospectively studied every 6 months over 18 months. In addition to bowel symptom interference and abdominal pain, measures of personality (neuroticism), childhood abuse history, depression, and anxiety were obtained. The hypothesized model was tested via Path Modelling. Results Childhood abuse was found to be directly associated with neuroticism but only indirectly associated with baseline interference and mood disorders (via neuroticism). The data further supported an ongoing cycle of elevations in mood disorders and pain/interference by bowel symptoms. The data supported direct effects of interference at one time point on interference at the subsequent time point in addition to indirect effects of prior anxiety and depression. Repeating the model with pain frequency as the outcome yielded almost identical findings which suggests the findings are generalized across domains of symptoms and quality-of-life. Conclusion Our data provide support for a model characterized by a ‘vicious circle’ between mood disorders and FGID symptoms in adulthood, with initial input from early life factors. PMID:24917988

Emerald ash borer (EAB), Agrilus planipennis, is a serious invasive forest pest in North America responsible for killing tens to hundreds of millions of ash trees since it was accidentally introduced in the 1990 s. Although host-plant resistance and natural enemies are known to be important sources of mortality for EAB in Asia, less is known about the importance of different sources of mortality at recently colonized sites in the invaded range of EAB, and how these relate to host tree crown condition. To further our understanding of EAB population dynamics, we used a large-scale field experiment and life-table analyses to quantify the fates of EAB larvae and the relative importance of different biotic mortality factors at 12 recently colonized sites in Maryland. We found that the fates of larvae were highly dependent on EAB life stage and host tree crown condition. In relatively healthy trees (i.e., with a low EAB infestation) and for early instars, host tree resistance was the most important mortality factor. Conversely, in more unhealthy trees (i.e., with a moderate to high EAB infestation) and for later instars, parasitism and predation were the major sources of mortality. Life-table analyses also indicated how the lack of sufficient levels of host tree resistance and natural enemies contribute to rapid population growth of EAB at recently colonized sites. Our findings provide further evidence of the mechanisms by which EAB has been able to successfully establish and spread in North America.

Recently, several robotic solutions for the elderly have been proposed. However, to date, the diffusion of these devices has been limited: available robots are too cumbersome, awkward, and expensive to become widely adopted. Another key issue which reduces the appeal of assistive robots is the lack of socio-emotional interaction: affective interchanges represent key requirements to create sustainable relationships between elderly and robots. In this paper, we propose a new approach to enhance the acceptability of robotic systems, based on the introduction of affective dimensions in human-robot interaction. This strategy is aimed at designing a new generation of relational and cognitive robots fusing information from embodied unobtrusive sensory interfaces. The final objective is to develop embodied interfaces, which are able to learn and adapt their affective responses to the user's behavior. User and robot will engage in natural interactions, involving verbal and non-verbal communication, improving empathic exchange of moods and feelings. Relevant independent living and quality of life related issues will be addressed: on-going monitoring of health parameters, assistance in everyday's activities, social support and cognitive/physical exercises. We expect that the proposed strategy will enhance the user's acceptance and adoption of the assistive robotic system.

Low protein provision in utero and post-partum may induce metabolic disorders in adulthood. Studies in mink have mainly focused on short-term consequences of low protein provision in utero whereas the long-term responses to low protein (LP) provision in metabolically programmed mink are unknown. We investigated whether low protein provision in utero affects the long-term response to adequate (AP) or LP provision after weaning in male mink. Eighty-six male mink were exposed to low (19% of ME from CP; crude protein) or adequate (31% of ME from CP) protein provision in utero, and to LP (~20% of ME from CP) or AP (30-42% of ME from CP) provision post-weaning. Being metabolically programmed by low protein provision in utero did not affect the response to post-weaning diets. Dietary protein content in the LP feed after weaning was below requirements; evidenced by lower nitrogen retention (p < 0.001) preventing LP mink from attaining their growth potential (p < 0.02). LP mink had a lower liver, pancreas and kidney weight (p < 0.05) as well as lower plasma IGF-1 concentrations at 8 and 25 (p < 0.05) weeks, and a higher incidence of hepatic lipidosis at 25 weeks (p < 0.05). Furthermore, LP mink had a higher body fat (p < 0.05) and lower body CP content (p < 0.05) at 50 weeks of age. It is concluded that some effects of low protein provision in utero can be alleviated by an adequate nutrient supply post-partum. However, long-term exposure to low protein provision in mink reduces their growth potential and induces transient hepatic lipidosis and modified body composition.

Depression and memory difficulties are among the most common complaints voiced by patients with multiple sclerosis (MS). Nevertheless, little is known about how depression might affect patients' perceptions of their memory difficulties. The present investigation was designed to explore this issue. Results supported a model that integrates aspects of Beck's theory of depression and the concept of depressive realism. Consistent with the depressive realism literature, nondepressed MS patients significantly overestimated their everyday memory compared with their actual performance on verbal memory and attention/concentration indices, whereas moderately depressed patients' everyday memory ratings mirrored their actual neuropsychological performance. Supporting Beck's negative cognitive schema notion, mildly depressed patients significantly overestimated their memory difficulties. Implications for the treatment of memory problems among MS patients are discussed.

Cognition, negative symptoms, and depression are potential predictors of disability in schizophrenia. We present analyses of pooled data from four separate studies (all n>169; total n=821) that assessed differential aspects of disability and their potential determinants. We hypothesized that negative symptoms would predict social outcomes, but not vocational functioning or everyday activities and that cognition and functional capacity would predict vocational functioning and everyday activities but not social outcomes. The samples were rated by clinician informants for their everyday functioning in domains of social and vocational outcomes, and everyday activities, examined with assessments of cognition and functional capacity, rated clinically with the Positive and Negative Syndrome Scale (PANSS) and self-reporting depression. We computed a model that tested the hypotheses described above and compared it to a model that predicted that negative symptoms, depression, cognition, and functional capacity had equivalent influences on all aspects of everyday functioning. The former, specific relationship model fit the data adequately and we subsequently confirmed a similar fit within all four samples. Analyses of the relative goodness of fit suggested that this specific model fit the data better than the more general, equivalent influence predictor model. We suggest that treatments aimed at cognition may not affect social functioning as much as other aspects of disability, a finding consistent with earlier research on the treatment of cognitive deficits in schizophrenia, while negative symptoms predicted social functioning. These relationships are central features of schizophrenia and treatment efforts should be aimed accordingly. PMID:25868935

This study examined the relative influence of environmental variables (corridor width and brightness) and signage (directional and exit signs), when presented in competition, on participants' route-choices in two situational variables (everyday vs. emergency), during indoor wayfinding in virtual environments. A virtual reality-based methodology was used. Thus, participants attempted to find a room (everyday situation) in a virtual hotel, followed by a fire-related emergency egress (emergency situation). Different behaviours were observed. In the everyday situation, for no-signs condition, participants choose mostly the wider and brighter corridors, suggesting a heavy reliance on the environmental affordances. Conversely, for signs condition, participants mostly complied with signage, suggesting a greater reliance on the signs rather than on the environmental cues. During emergency, without signage, reliance on environmental affordances seems to be affected by the intersection type. In the sign condition, the reliance on environmental affordances that started strong decreases along the egress route.

Our everyday shopping practices are increasingly marketed as opportunities to 'make a difference' via our ethical consumption choices. In response to a growing body of work detailing the ways in which specific alignments of 'ethics' and 'consumption' are mediated, we explore how 'ethical' opportunities such as the consumption of Fairtrade products are recognized, experienced and taken-up in the everyday. The 'everyday' is approached here via a specially commissioned Mass Observation directive, a volunteer panel of correspondents in the UK. Our on-going thematic analysis of their autobiographical accounts aims to explore a complex unevenness in the ways 'ordinary' people experience and negotiate calls to enact their ethical agency through consumption. Situating ethical consumption, moral obligation and choice in the everyday is, we argue, important if we are to avoid both over-exaggerating the reflexive and self-conscious sensibilities involved in ethical consumption, and, adhering to a reductive understanding of ethical self-expression.

Contextual factors are crucial for evaluative research in psychology, as they provide insights into what works, for whom, in what circumstances, in what respects, and why. Studying behavior in context, however, poses numerous methodological challenges. Although a comprehensive framework for classifying methods seeking to quantify biopsychosocial aspects in everyday contexts was recently proposed, this framework does not contemplate contributions from observational methodology. The aim of this paper is to justify and propose a more general framework that includes observational methodology approaches. Our analysis is rooted in two general concepts: ecological validity and methodological complementarity. We performed a narrative review of the literature on research methods and techniques for studying daily life and describe their shared properties and requirements (collection of data in real time, on repeated occasions, and in natural settings) and classification criteria (eg, variables of interest and level of participant involvement in the data collection process). We provide several examples that illustrate why, despite their higher costs, studies of behavior and experience in everyday contexts offer insights that complement findings provided by other methodological approaches. We urge that observational methodology be included in classifications of research methods and techniques for studying everyday behavior and advocate a renewed commitment to prioritizing ecological validity in behavioral research seeking to quantify biopsychosocial aspects.

Life satisfaction and self-efficacy are important aspects of stroke rehabilitation. Previous research focuses on Western stroke survivors, neglecting the stroke experience in the Middle East. This research was conducted in Kuwait and entailed both quantitative and qualitative phases to obtain a more comprehensive, clinically relevant understanding of self-efficacy and life satisfaction during stroke rehabilitation in this culture. The aims were to: 1) investigate the relationships between self-efficacy and life satisfaction in female patients affected by stroke (Phase 1); and 2) explore health professionals' views regarding the importance of self-efficacy and possible strategies for enhancing self-efficacy during rehabilitation, through semi-structured interviews (Phase 2). Significant correlations were found between patients' general self-efficacy, and psychosocial adaptation self-efficacy following stroke. Self-efficacy (both general and psychosocial adaptation) showed significant correlations with life satisfaction post-stroke. Health professionals (more than half of whom were physiotherapists) recognised the importance of self-efficacy within stroke rehabilitation and identified five main ways to increase self-efficacy during stroke rehabilitation. These were to: 1) motivate and encourage patients; 2) provide more education about stroke and rehabilitation; 3) identify change; 4) offer a high-quality environment and therapy; and 5) set goals. In conclusion, psychosocial self-efficacy was identified as having a stronger relationship to life satisfaction compared with general self-efficacy within this sample of Kuwaiti female patients. Health professionals suggested various strategies for enhancing self-efficacy and thereby life satisfaction post-stroke during the rehabilitation process in Kuwait. Despite the collectivist culture of Kuwait, the findings indicate that the patient's own confidence and sense of responsibility for progress may be relevant to
