    2010-01-01

    Current theories of text processing say little about how author’s narrative choices, including the introduction of small mysteries, can affect readers’ narrative experiences. Gerrig, Love, and McKoon (2009) provided evidence that one type of small mystery—a character introduced without information linking him or her to the story—affects readers’ moment-by-moment processing. For that project, participants read stories that introduced characters by proper name alone (e.g., Judy) or with information connecting the character to the rest of the story (e.g., our principal Judy). In an on-line recognition probe task, responses to the character’s name three lines after his or her introduction were faster when the character had not been introduced with connecting information, suggesting that the character remained accessible awaiting resolution. In the four experiments in this paper, we extended our theoretical analysis of small mysteries. In Experiments 1 and 2, we found evidence that trait information (e.g., daredevil Judy) is not sufficient to connect a character to a text. In Experiments 3 and 4, we provide evidence that the moment-by-moment processing effects of such small mysteries also affect readers’ memory for the stories. We interpret the results in terms of Kintsch’s Construction-Integration model (1988) of discourse processing. PMID:20438273

    This article presents the results of interviews conducted with children regarding their cognitive and affective responses toward a narrative and a non-narrative cartoon. The findings will be used to further explore the role of a narrative in motivating continued active videogame play. Twenty children (8-11 years old of mixed gender) watched two cartoons (narrative and non-narrative) and were subsequently interviewed. A thematic matrix was used to analyze the interviews. The narrative cartoon (n = 11) was only slightly preferred compared with the non-narrative one (n = 9), with little difference among the participants. The theme categories identified during the analyses were plot, characters, and suggestions. The fight scenes were mentioned by the children as a likeable aspect of the narrative cartoon. In the non-narrative cartoon, the vast majority (n = 17) liked the information about physical activity that was provided. The children enjoyed the appearance and personalities of the characters in both cartoons. A discrepancy in the data about the fight scenes (narrative cartoon) and characters (both cartoons) was found among the female participants (i.e., some girls did not like the fight and thought the characters were too aggressive). However, most of the children wanted to see more action in the story, an increase in the number of fight scenes (narrative cartoon), or more information about exercise and examples of exercises they could do (non-narrative cartoon). They also suggested adding a game to the non-narrative cartoon, including more characters, and improving the animation in both cartoons. The children preferred the narrative cartoon because of the story and the fight. Some gender differences were found, which further studies should investigate.

  6. Why Narrating Changes Memory: A Contribution to an Integrative Model of Memory and Narrative Processes.

    2016-06-01

    This paper aims to reflect on the relation between autobiographical memory (ME) and autobiographical narrative (NA), examining studies on the effects of narrating on the narrator and showing how studying these relations can make more comprehensible both memory's and narrating's way of working. Studies that address explicitly on ME and NA are scarce and touch this issue indirectly. Authors consider different trends of studies of ME and NA: congruency vs incongruency hypotheses on retrieving, the way of organizing memories according to gist or verbatim format and their role in organizing positive and negative emotional experiences, the social roots of ME and NA, the rules of conversation based on narrating. Analysis of investigations leads the Authors to point out three basic results of their research. Firstly, NA transforms ME because it narrativizes memories according to a narrative format. This means that memories, when are narrated, are transformed in stories (verbal language) and socialised. Secondly, the narrativization process is determined by the act of telling something within a communicative situation. Thus, relational situation of narrating act, by modifying the story, modifies also memories. The Authors propose the RE.NA.ME model (RElation, NArration, MEmory) to understand and study ME and NA. Finally, this study claims that ME and NA refer to two different types of processes having a wide area of overlapping. This is due to common social, developmental and cultural roots that make NA to include part of ME (narrative of memory) and ME to include part of NA (memory of personal events that have been narrated).

    Full Text Available Transmedia narrators can use the intermediacy of images and text as a foundation to develop story networks. These narrators can also use various forms of technology to recreate a variety of aesthetic responses in readers. In this study, we analyzed the narrative strategies of adaptation in examples of transmedia adaptation among winners of international picture book awards. In artistic terms, the horizons of expectation of adapters, the readers of fiction, and the inviting structures extended from intermediacy play key roles in aesthetic communication. How adapters use the materials of intermediacy as filler or to expand on negative speculation also influences the relaying process. In this study, we clarified that in addition to considering aesthetic judgments, adaptation must also adhere to the economy of aesthetics.

  10. Psychological Functions of Semiotic Borders in Sense-Making: Liminality of Narrative Processes.

    Science.gov (United States)

    De Luca Picione, Raffaele; Valsiner, Jaan

    2017-08-01

    In this paper we discuss the semiotic functions of the psychological borders that structure the flow of narrative processes. Each narration is always a contextual, situated and contingent process of sensemaking, made possible by the creation of borders, such as dynamic semiotic devices that are capable of connecting the past and the future, the inside and the outside, and the me with the non-me. Borders enable us to narratively construct one's own experiences using three inherent processes: contextualization, intersubjective positioning and setting of pertinence. The narrative process - as a subjective articulation of signs in a contingent social context - involves several functions of semiotic borders: separation, differentiation, distinction-making, connection, articulation and relation-enabling. The relevant psychological aspect highlighted here is that a border is a semiotic device which is required for both maintaining stability and inducing transformation at the same time. The peculiar dynamics and the semiotic structure of borders generate a liminal space, which is characterized by instability, by a blurred space-time distinction and by ambiguities in the semantic and syntactic processes of sensemaking. The psychological processes that occur in liminal space are strongly affectively loaded, yet it is exactly the setting and activation of liminality processes that lead to novelty and creativity and enable the creation of new narrative forms.

    While the individual contributions of narrative and emotion processes to psychotherapy outcome have been the focus of recent interest in psychotherapy research literature, the empirical analysis of narrative and emotion integration has rarely been addressed. The Narrative-Emotion Processes Coding System (NEPCS) was developed to provide researchers with a systematic method for identifying specific narrative and emotion process markers, for application to therapy session videos. The present study examined the relationship between NEPCS-derived problem markers (same old storytelling, empty storytelling, unstoried emotion, abstract storytelling) and change markers (competing plotlines storytelling, inchoate storytelling, unexpected outcome storytelling, and discovery storytelling), and treatment outcome (recovered versus unchanged at therapy termination) and stage of therapy (early, middle, late) in brief emotion-focused (EFT), client-centred (CCT), and cognitive (CT) therapies for depression. Hierarchical linear modelling analyses demonstrated a significant Outcome effect for inchoate storytelling (p = .037) and discovery storytelling (p = .002), a Stage × Outcome effect for abstract storytelling (p = .05), and a Stage × Outcome × Treatment effect for competing plotlines storytelling (p = .001). There was also a significant Stage × Outcome effect for NEPCS problem markers (p = .007) and change markers (p = .03). The results provide preliminary support for the importance of assessing the contribution of narrative-emotion processes to efficacious treatment outcomes in EFT, CCT, and CT treatments of depression.

    Full Text Available The aim of the study was to verify the hypothesis that positive affective tone of narratives is connected to the experience of posttraumatic growth among transplant patients. Kidney transplant patients (N = 51 and liver transplant patients (N = 48 participated in the study. In the first stage, about 10 weeks after transplant, the participants told two stories about important, freely chosen events from their lives. During the second meeting 10-12 months later we measured posttraumatic growth. Results indicated that the affective tone of narratives about past events was associated with the level of post-traumatic growth measured 10-12 months later. This proves that the affective tone of narratives about life, understood as a relatively constant individual characteristic, promote posttraumatic growth.

    Obesity is a chronic, relapsing medical condition that results from an imbalance of energy expenditure and consumption. It is a leading cause of preventable illness, disability and premature death. The causes of obesity are multifactorial and include behavioural, socioeconomic, genetic, environmental and psychosocial factors. Rarely are endocrine diseases, e.g., hypothyroidism or Cushing's syndrome, the cause of obesity. What is less understood is how obesity affects the endocrine system. In this review, we will discuss the impact of obesity on multiple endocrine systems, including the hypothalamic-pituitary axis, changes in vitamin D homeostasis, gender steroids and thyroid hormones. We will also examine the renin angiotensin aldosterone system and insulin pathophysiology associated with obesity. We will provide a general overview of the biochemical changes that can be seen in patients with obesity, review possible aetiologies of these changes and briefly consider current guidelines on their management. This review will not discuss endocrine causes of obesity. © 2017 World Obesity Federation.

    Recent studies suggest that it is not simply the expression of emotion or emotional arousal in session that is important, but rather it is the reflective processing of emergent, adaptive emotions, arising in the context of personal storytelling and/or Emotion-Focused Therapy (EFT) interventions, that is associated with change. To enhance narrative-emotion integration specifically in EFT, Angus and Greenberg originally identified a set of eight clinically derived narrative-emotion integration markers were originally identified for the implementation of process-guiding therapeutic responses. Further evaluation and testing by the Angus Narrative-Emotion Marker Lab resulted in the identification of 10 empirically validated Narrative-Emotion Process (N-EP) markers that are included in the Narrative-Emotion Process Coding System Version 2.0 (NEPCS 2.0). Based on empirical research findings, individual markers are clustered into Problem (e.g., stuckness in repetitive story patterns, over-controlled or dysregulated emotion, lack of reflectivity), Transition (e.g., reflective, access to adaptive emotions and new emotional plotlines, heightened narrative and emotion integration), and Change (e.g., new story outcomes and self-narrative discovery, and co-construction and re-conceptualization) subgroups. To date, research using the NEPCS 2.0 has investigated the proportion and pattern of narrative-emotion markers in Emotion-Focused, Client-Centered, and Cognitive Therapy for Major Depression, Motivational Interviewing plus Cognitive Behavioral Therapy for Generalized Anxiety Disorder, and EFT for Complex Trauma. Results have consistently identified significantly higher proportions of N-EP Transition and Change markers, and productive shifts, in mid- and late phase sessions, for clients who achieved recovery by treatment termination. Recovery is consistently associated with client storytelling that is emotionally engaged, reflective, and evidencing new story outcomes and self-narrative

    Directory of Open Access Journals (Sweden)

    2012-08-01

    Full Text Available The art of narrative stems from the art of rhetoric and modes of persuasion and in this meaning is understood not just as a form of entertainment but also as a tool of communication. Any narrative communicates and conveys a message. Narrative is an important aspect of culture and as a ubiquitous component of human communication is conveyed by different works of art (literature, music, painting, sculpture, and illustrates events, emotions, phenomena and occurrences. Narrative as a form of communication involves its participants, a teller and a receiver of the message. The relation and the distance between the participants of the narrative communication process may have a different configuration and presents different effect of closeness and distance in narrative. In this meaning narrative is not just the art of telling stories, but it serves various functions, it communicates information, expresses emotions and personal events, transmits morals and cultural knowledge, provides entertainment and also helps in many ways to depict thoughts and feelings, along with disclosing the beauty of language. Narrative knowledge and narrative perception of social and cultural processes, is one of the most natural ways for a human being to acquire and organize their knowledge about the world. The ability to create narratives leads to a better understanding of the surrounding reality, and significantly influences the interpretation of social and cultural relationships.

  1. Narrative ethics for narrative care.

    Baldwin, Clive

    2015-08-01

    Narrative permeates health care--from patients' stories taken as medical histories to the development of health policy. The narrative approach to health care has involved the move from narratives in health care as objects of study to the lens through which health care is studied and, more recently, to narrative as a form of care. In this paper, I argue that narrative care requires a move in the field of ethics--from a position where narratives are used to inform ethical decision making to one in which narrative is the form and process of ethical decision making. In other words, I argue for a narrative ethics for narrative care. The argument is relatively straightforward. If, as I argue, humans are narrative beings who make sense of themselves, others, and the world in and through narrative, we need to see our actions as both narratively based and narratively contextual and thus understanding the nature, form, and content of the narratives of which we are a part, and the process of narrativity, provides an intersubjective basis for ethical action.

    The article discusses anthropology, ethnographic method, and narrative as possible ways of coming to know subjects' experiences and the feelings they attribute to them. From an anthropological perspective, the sociocultural universe is taken as a point of reference in understanding the meaning of the processes of health and sickness, using a dense ethnographic description from an interpretivist analytical approach. In this context, narratives afford possible paths to understanding how subjective human experiences are shared and how behavior is organized, with a special focus on meaning, the process by which stories are produced, relations between narrator and other subjects, processes of knowledge, and the manifold ways in which experience can be captured.

    Access to affected people pays an important role in United Nation Organization for Coordination and Humanitarian Affairs (OCHA). The aim of this article is to identify the main obstacles of humanitarian access and the humanitarian organization responses to these obstacles and finally suggest some recommendations and strategies. In this narrative study the researchers searched in different databases. This study focused on the data from five countries in the following areas: access challenges and constraints to affected population and response strategies selected for operations in the affected countries by humanitarian organizations. Three main issues were studied: security threats, bureaucratic restrictions and indirect constraint, which each of them divided to three subcategories. Finally, nine related subcategories emerged from this analysis. Most of these constraints relate to political issues. Changes in policy structures, negotiations and advocacy can be recommended to solve most of the problems in access issues.

The purpose of this study is not limited to disability and to special education needs but goes further than that encompassing isolation and/or exclusions. As far as the university system is concerned, it becomes significant to enquire about the inclusion process, in this case by means of a narrative approach, bearing in mind that organizational and learning models, together with access modes may give rise to social exclusion.Università e territorio: costruzione di una rete narrativa per l’implementazione dei processi inclusiviIl costrutto di inclusione nelle sue complesse sfaccettature mirate al superamento delle barriere all’apprendimento e alla partecipazione, ha guidato il presente lavoro di ricerca in ambito universitario alla luce della pedagogia e didattica speciale, sulla base dei parametri dell’Index for Inclusion, rilevando i livelli di progettazione integrata con il territorio.

However, the balance of familiarity and alienness is not static, but can be cultivated through e.g. psychotherapy. Following this line of thought, I present the idea that narrativising experiences can play an important...... role in processes of appropriating such embodied self-alienness. Importantly, the notion of narrative used is that of a scalar conception of narrativity as a variable quality of experience that comes in degrees. From this perspective, narrative appropriation is a process of gradually attributing...

  7. Inference or enaction? The impact of genre on the narrative processing of other minds.

    Directory of Open Access Journals (Sweden)

    James Carney

    Full Text Available Do narratives shape how humans process other minds or do they presuppose an existing theory of mind? This study experimentally investigated this problem by assessing subject responses to systematic alterations in the genre, levels of intentionality, and linguistic complexity of narratives. It showed that the interaction of genre and intentionality level are crucial in determining how narratives are cognitively processed. Specifically, genres that deployed evolutionarily familiar scenarios (relationship stories were rated as being higher in quality when levels of intentionality were increased; conversely, stories that lacked evolutionary familiarity (espionage stories were rated as being lower in quality with increases in intentionality level. Overall, the study showed that narrative is not solely either the origin or the product of our intuitions about other minds; instead, different genres will have different-even opposite-effects on how we understand the mind states of others.

  8. The Narrative Reproduction of Contemporary Montenegrin Identity in The Process of Euroatlantic Intergrations (Part I

    Directory of Open Access Journals (Sweden)

    Branko Banović

    2016-03-01

    Full Text Available If we conceptualize reality as a large narrative we “build ourselves into” as social beings, and consider social activities and identities as narratively mediated, the full extent of the capacity of narratives in the creation, shaping, transmission and reconstruction of contemporary social identities, as well as the reproduction of the concept of nation in everyday life becomes apparent. The imagined Euro- Atlantic future of Montenegro demands certain narrative interpretations of the past, which, in latter stages tend to become meta-narratives susceptible to consensus. The linkage of significant historical events to the process of Euro-Atlantic integrations of Montenegro is preformed through different meta-discursive practices, most often through ceremonial evocations of memories of significant events from the recent as well as further history of Montenegro. In this context, celebrations of Statehood Day and Independence Day are especially important, as they serve as reminders of the decisions of the Congress of Berlin, the Podgorica Assembly, the antifascist struggle of World War II and the independence of Montenegro attained through the referendum held in 2006. The clearly defined key points, along with the logical coherence the narrative is based on, provide the narrative with a certain “flexibility” which enables it to take in new elements. Narrative interpretations of the past have a significant role in the reproduction of the nation, as well as the shaping and consolidation of a desirable national identity, while the established narrative continuity between the past, present and imagined Euro-Atlantic future of Montenegro emerges as the “official” mediator in the reproduction of contemporary Montenegrin identity in the process of Euro-Atlantic integration. In order to fully comprehend this narrative, it is advisable to conceptualize it both in a synchronic as well as a diachronic perspective, as can be shown in two charts which

    Previous research suggests that narrative and expository texts differ in the extent to which they prompt students to integrate to-be-learned content with relevant prior knowledge during comprehension. We expand on previous research by examining on-line processing and representation in memory of to-be-learned content that is embedded in narrative or expository texts. We are particularly interested in how differences in the use of relevant prior knowledge leads to differences in terms of levels of discourse representation (textbase vs. situation model). A total of 61 university undergraduates in Expt 1, and 160 in Expt 2. In Expt 1, subjects thought out loud while comprehending circulatory system content embedded in a narrative or expository text, followed by free recall of text content. In Expt 2, subjects read silently and completed a sentence recognition task to assess memory. In Expt 1, subjects made more associations to prior knowledge while reading the expository text, and recalled more content. Content recall was also correlated with amount of relevant prior knowledge for subjects who read the expository text but not the narrative text. In Expt 2, subjects reading the expository text (compared to the narrative text) had a weaker textbase representation of the to-be-learned content, but a marginally stronger situation model. Results suggest that in terms of to-be-learned content, expository texts trigger students to utilize relevant prior knowledge more than narrative texts.

    The present study examined narrative identity in adolescence (14-18 years) in terms of narrative content and processes of identity development. Age- and gender-related differences in narrative patterns in turning point memories and gender differences in the content and functions for sharing those memories were examined, as was the relationship between narrative patterns and self-esteem. The narrative patterns focused on were meaning-making (learning from past events) and emotionality of the narratives, specified as overall positive emotional tone and redemptive sequencing. Results showed an age-related increase in meaning-making but no gender differences in the degree of meaning-making. Results further showed that gender predicted self-esteem and that boys evidenced higher self-esteem. Emotionality also predicted self-esteem; this was especially true for redemption and for boys. In terms of telling functions, girls endorsed more relational reasons for telling memories than did boys. Results are discussed in terms of potential gendered and nongendered pathways for identity development in adolescence. Copyright 2009 APA, all rights reserved

    To investigate the current state of knowledge about emotional intelligence and affective events that arise during nursing students' clinical placement experiences. Narrative literature review. CINAHL, MEDLINE, PsycINFO, Scopus, Web of Science, ERIC and APAIS-Health databases published in English between 1990 and 2016. Data extraction from and constant comparative analysis of ten (10) research articles. We found four main themes: (1) emotional intelligence buffers stress; (2) emotional intelligence reduces anxiety associated with end of life care; (3) emotional intelligence promotes effective communication; and (4) emotional intelligence improves nursing performance. The articles we analysed adopted a variety of emotional intelligence models. Using the Ashkanasy and Daus "three-stream" taxonomy (Stream 1: ability models; 2: self-report; 3: mixed models), we found that Stream 2 self-report measures were the most popular followed by Stream 3 mixed model measures. None of the studies we surveyed used the Stream 1 approach. Findings nonetheless indicated that emotional intelligence was important in maintaining physical and psychological well-being. We concluded that developing emotional intelligence should be a useful adjunct to improve academic and clinical performance and to reduce the risk of emotional distress during clinical placement experiences. We call for more consistency in the use of emotional intelligence tests as a means to create an empirical evidence base in the field of nurse education. Copyright © 2017 Elsevier Ltd.

    To the extent that stereotype and identity threat undermine academic performance, social psychological interventions that lessen threat could buffer threatened students and improve performance. Two studies, each featuring a longitudinal field experiment in a mixed-ethnicity middle school, examined whether a values affirmation writing exercise could attenuate the achievement gap between Latino American and European American students. In Study 1, students completed multiple self-affirmation (or control) activities as part of their regular class assignments. Latino American students, the identity threatened group, earned higher grades in the affirmation than control condition, whereas White students were unaffected. The effects persisted 3 years and, for many students, continued into high school by lifting their performance trajectory. Study 2 featured daily diaries to examine how the affirmation affected psychology under identity threat, with the expectation that it would shape students' narratives of their ongoing academic experience. By conferring a big-picture focus, affirmation was expected to broaden construals, prevent daily adversity from being experienced as identity threat, and insulate academic motivation from identity threat. Indeed, affirmed Latino American students not only earned higher grades than nonaffirmed Latino American students but also construed events at a more abstract than concrete level and were less likely to have their daily feelings of academic fit and motivation undermined by identity threat. Discussion centers on how social-psychological processes propagate themselves over time and how timely interventions targeting these processes can promote well-being and achievement.

    First-person narratives are becoming a popular means to communicate health risk information. Although studies show they can increase risk perception and motivate health behaviours compared to statistical messages, more research on the conditions in which they are particularly likely to have effects is needed. In this study, we tested a moderator related to how information is processed. Specifically, we hypothesised that thinking in terms of emotions and personal experiences - known as experiential information processing - would increase people's responsiveness to a narrative. Female college students (N = 138) who reported indoor tanning were randomly assigned to read a first-person narrative message or a statistical message about the risks of skin cancer. Prior to reading the message, the women received instructions that would activate either experiential or rational information processing. Participants then reported their risk perceptions of skin cancer, worry about skin cancer and behaviour intentions related to skin cancer. Analyses showed that message type and information processing interacted to influence risk perceptions and worry. Consistent with hypotheses, participants reported the highest risk perception and worry when they used an experiential information system prior to reading the narrative message. There were no effects on behaviour intentions. Implications of these findings are discussed.

    Full Text Available This is a longitudinal study of the identity process through times of dramatic social change. Using a narrative psychological approach this research follows the life stories of five Egyptian bloggers as they write their stories on online blogs over the course of the three years following the 2011 revolution, at which time Egypt has witnessed major social and political changes. The aim is to understand the identity process of individuals as they develop and adapt through changing social contexts and how they create alternative social relations as they engage in prefigurative politics. The findings shed light on how ruptures trigger a process of reflexivity, adaptive learning, and sense-making that facilitates coping and the reconstruction of a positive identity after ruptures. It also suggests that the narration of the experience of rupture through storytelling creates a heightened sense of agency in individuals’ ability to create new meanings of their world in spite of the socio-cultural and political constraints. This study presents narratives as an informing methodological resource that connects identity process with social representations and emphasizes the value of storytelling as an integral part of the adaptation process.

  16. The stories we tell: how age, gender, and forgiveness affect the emotional content of autobiographical narratives.

    2018-04-01

    Researchers have been attempting to understand the variables that predict differences in autobiographical narratives, given that these differences often reveal important information about the psychological characteristics of the person providing the narrative. A sample of young adults (n = 80) and older adults (n = 80) completed a battery of self-report measures in addition to an autobiographical narrative task in which they described a negative emotional experience. These narratives were transcribed and entered into a text analysis program. Results indicated a significant three-way interaction (age × gender × forgiveness) for negative emotion words. Results also indicated two significant two-way interactions (age × forgiveness and gender × forgiveness) and one significant main effect for anger words. There were no significant findings related to anxiety or sad words. Results are discussed in the context of Socioemotional Selectivity Theory, which asserts that social and emotional goals shift throughout the lifespan such that older adults are more motivated to regulate their emotions than young adults. Clinical applications and future directions are discussed.

    Natural language processing (NLP) tasks are commonly decomposed into subtasks, chained together to form processing pipelines. The residual error produced in these subtasks propagates, adversely affecting the end objectives. Limited availability of annotated clinical data remains a barrier to reaching state-of-the-art operating characteristics using statistically based NLP tools in the clinical domain. Here we explore the unique linguistic constructions of clinical texts and demonstrate the loss in operating characteristics when out-of-the-box part-of-speech (POS) tagging tools are applied to the clinical domain. We test a domain adaptation approach integrating a novel lexical-generation probability rule used in a transformation-based learner to boost POS performance on clinical narratives. Two target corpora from independent healthcare institutions were constructed from high frequency clinical narratives. Four leading POS taggers with their out-of-the-box models trained from general English and biomedical abstracts were evaluated against these clinical corpora. A high performing domain adaptation method, Easy Adapt, was compared to our newly proposed method ClinAdapt. The evaluated POS taggers drop in accuracy by 8.5-15% when tested on clinical narratives. The highest performing tagger reports an accuracy of 88.6%. Domain adaptation with Easy Adapt reports accuracies of 88.3-91.0% on clinical texts. ClinAdapt reports 93.2-93.9%. ClinAdapt successfully boosts POS tagging performance through domain adaptation requiring a modest amount of annotated clinical data. Improving the performance of critical NLP subtasks is expected to reduce pipeline error propagation leading to better overall results on complex processing tasks.

    2009-03-01

    The present research investigated the longitudinal relations between personality traits and narratives. Specifically, the authors examined how individual differences in 170 college students' narratives of personality change (a) were predicted by personality traits at the beginning of college, (b) related to actual changes and perceived changes in personality traits during college, and (c) related to changes in emotional health during college. Individual differences in narratives of personality trait change told in the 4th year of college fell into 2 dimensions: affective processing, characterized by positive emotions, and exploratory processing, characterized by meaning making and causal processing. Conscientious, open, and extraverted freshmen told exploratory stories of change as seniors. Emotionally healthy freshmen told stories of change that were high in positive affect. Both positive affective and exploratory stories corresponded to change in emotional stability and conscientiousness during college above and beyond the effects of perceived changes in these traits. In addition, both positive affective and exploratory narratives corresponded to increases in emotional health during college independent of the effects of changes in personality traits. These findings improve our understanding of how individuals conceptualize their changing identity over time.

    Oppenheim, David

    2006-01-01

    Studies using narratives with children and parents offer ways to study affective meaning-making processes that are central in many theories of developmental psychopathology. This paper reviews theory regarding affective meaning making, and argues that narratives are particularly suited to examine such processes. The review of narrative studies and methods is organized into three sections according to the focus on child, parent, and parent-child narratives. Within each focus three levels of analysis are considered: (a) narrative organization and coherence, (b) narrative content, and (c) the behavior/interactions of the narrator(s). The implications of this research for developmental psychopathology and clinical work are discussed with an emphasis on parent-child jointly constructed narratives as the meeting point of individual child and parent narratives.

  2. Affective processing in bilingual speakers: disembodied cognition?

    Science.gov (United States)

    Pavlenko, Aneta

    2012-01-01

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

    M.A. Despite the fact that same-sex marriage was legalised in South Africa in 2006, predominant societal attitudes towards gay couples remain negative. In the face of this opposition, samesex couples who choose to marry are often in need of support, but may find that support lacking because of the stigma associated with being gay. This study sought to explore what happens with family support in particular when a gay couple chooses to marry legally. Using a narrative qualitative method, inf...

    Conover, Kelly; Daiute, Colette

    2017-06-01

    This qualitative study utilized a narrative approach to explore the process of self-regulation in adolescents and to examine the functions of various relational genres on psychological state and context expressions in this process. Nineteen participants, who live in high-risk settings were recruited from a youth development and life skills program located at an urban public high school in the United States. The goal of this project is to craft a process method for research and practice on adolescents' self-regulation while providing evidence for self-regulation being a complex process. This research uses an exploratory study design with a narrative approach, utilizing text message based activities in the method. Findings from the plot analysis suggest that for adolescents, the process of self-regulation begins as highly emotional and then becomes a more emotionally and cognitively balanced process. In addition, adolescents utilize different strategies to resolve conflict situations across different contexts and relational genres.

    Anderson, Claire; Kirkpatrick, Susan

    2016-06-01

    Introduction Narrative interviews place the people being interviewed at the heart of a research study. They are a means of collecting people's own stories about their experiences of health and illness. Narrative interviews can help researchers to better understand people's experiences and behaviours. Narratives may come closer to representing the context and integrity of people's lives than more quantitative means of research. Methodology Researchers using narrative interview techniques do not set out with a fixed agenda, rather they tend to let the interviewee control the direction, content and pace of the interview. The paper describes the interview process and the suggested approach to analysis of narrative interviews, We draw on the example from a study that used series of narrative interviews about people's experiences of taking antidepressants. Limitations Some people may find it particularly challenging to tell their story to a researcher in this way rather than be asked a series of questions like in a television or radio interview. Narrative research like all qualitative research does not set out to be generalisable and may only involve a small set of interviews.

  6. Affect intensity and processing fluency of deterrents.

    2013-01-01

    The theory of emotional intensity (Brehm, 1999) suggests that the intensity of affective states depends on the magnitude of their current deterrents. Our study investigated the role that fluency--the subjective experience of ease of information processing--plays in the emotional intensity modulations as reactions to deterrents. Following an induction phase of good mood, we manipulated both the magnitude of deterrents (using sets of photographs with pre-tested potential to instigate an emotion incompatible with the pre-existent affective state--pity) and their processing fluency (normal vs. enhanced through subliminal priming). Current affective state and perception of deterrents were then measured. In the normal processing conditions, the results revealed the cubic effect predicted by the emotional intensity theory, with the initial affective state being replaced by the one appropriate to the deterrent only in participants exposed to the high magnitude deterrence. In the enhanced fluency conditions the emotional intensity pattern was drastically altered; also, the replacement of the initial affective state occurred at a lower level of deterrence magnitude (moderate instead of high), suggesting the strengthening of deterrence emotional impact by enhanced fluency.

  7. Affective processes in human-automation interactions.

    This study contributes to the literature on automation reliance by illuminating the influences of user moods and emotions on reliance on automated systems. Past work has focused predominantly on cognitive and attitudinal variables, such as perceived machine reliability and trust. However, recent work on human decision making suggests that affective variables (i.e., moods and emotions) are also important. Drawing from the affect infusion model, significant effects of affect are hypothesized. Furthermore, a new affectively laden attitude termed liking is introduced. Participants watched video clips selected to induce positive or negative moods, then interacted with a fictitious automated system on an X-ray screening task At five time points, important variables were assessed including trust, liking, perceived machine accuracy, user self-perceived accuracy, and reliance.These variables, along with propensity to trust machines and state affect, were integrated in a structural equation model. Happiness significantly increased trust and liking for the system throughout the task. Liking was the only variable that significantly predicted reliance early in the task. Trust predicted reliance later in the task, whereas perceived machine accuracy and user self-perceived accuracy had no significant direct effects on reliance at any time. Affective influences on automation reliance are demonstrated, suggesting that this decision-making process may be less rational and more emotional than previously acknowledged. Liking for a new system may be key to appropriate reliance, particularly early in the task. Positive affect can be easily induced and may be a lever for increasing liking.

    2017-01-01

    In game narrative the central role of the protagonist becomes a challenge as the protagonist often conflates with the player character, which the author and the player share control over. This paper investigates whether knowledge of the player character’s alignment, i.e. the inner thoughts...... of the character, can influence how they decide to progress in a game. The player character’s alignment will present an internal conflict, which will sometimes conflict with the external goal of a game. It is investigated whether players are more likely to abandon their external goal, and ultimately change...... their in-game behaviour, when exposed to the internal conflict of their character. A test was conducted in which participants played through one of two similar versions of the same game; one in which they were exposed to the player character’s internal conflict, and another in which they were not. The test...

    Digital storytelling (DST) engages participants in a group-based process to create and share narrative accounts of life events. We present key evaluation findings of a 2-year, mixed-methods study that focused on effects of participating in the DST process on young Puerto Rican Latina's self-esteem, social support, empowerment, and sexual attitudes and behaviors. Quantitative results did not show significant changes in the expected outcomes. However, in our qualitative findings we identified several ways in which the DST made positive, health-bearing effects. We argue for the importance of "measuring down" to reflect the locally grounded, felt experiences of participants who engage in the process, as current quantitative scales do not "measure up" to accurately capture these effects. We end by suggesting the need to develop mixed-methods, culturally relevant, and sensitive evaluation tools that prioritize process effects as they inform intervention and health promotion. © The Author(s) 2016.

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

    2012-01-01

    This review summarizes the major discussion points of a symposium on stress modulation of cognitive and affective processes, which was held during the 2010 workshop on the neurobiology of stress (Boulder, CO, USA). The four discussants addressed a number of specific cognitive and affective factors that are modulated by exposure to acute or repeated stress. Dr David Morilak discussed the effects of various repeated stress situations on cognitive flexibility, as assessed with a rodent model of attentional set-shifting task, and how performance on slightly different aspects of this test is modulated by different prefrontal regions through monoaminergic neurotransmission. Dr Serge Campeau summarized the findings of several studies exploring a number of factors and brain regions that regulate habituation of various autonomic and neuroendocrine responses to repeated audiogenic stress exposures. Dr Kerry Ressler discussed a body of work exploring the modulation and extinction of fear memories in rodents and humans, especially focusing on the role of key neurotransmitter systems including excitatory amino acids and brain-derived neurotrophic factor. Dr Israel Liberzon presented recent results on human decision-making processes in response to exogenous glucocorticoid hormone administration. Overall, these discussions are casting a wider framework on the cognitive/affective processes that are distinctly regulated by the experience of stress and some of the brain regions and neurotransmitter systems associated with these effects.

    Full Text Available The comprehension of stories requires the reader to imagine the cognitive and affective states of the characters. The content of many stories is unpleasant, as they often deal with conflict, disturbance or crisis. Nevertheless, unpleasant stories can be liked and enjoyed. In this fMRI study, we used a parametric approach to examine (1 the capacity of increasing negative valence of story contents to activate the mentalizing network (cognitive and affective theory of mind, ToM, and (2 the neural substrate of liking negatively valenced narratives. A set of 80 short narratives was compiled, ranging from neutral to negative emotional valence. For each story mean rating values on valence and liking were obtained from a group of 32 participants in a prestudy, and later included as parametric regressors in the fMRI analysis. Another group of 24 participants passively read the narratives in a 3 Tesla MRI scanner. Results revealed a stronger engagement of affective ToM-related brain areas with increasingly negative story valence. Stories that were unpleasant, but simulatiously liked, selectively engaged the medial prefrontal cortex (mPFC, which might reflect the moral exploration of the story content. Further analysis showed that the more the mPFC becomes engaged during the reading of negatively valenced stories, the more coactivation can be observed in other brain areas related to the neural processing of affective ToM and empathy.

    The factors affecting medication-order processing time at one hospital were studied. The order processing time was determined by directly observing the time to process randomly selected new drug orders on all three work shifts during two one-week periods. An order could list more than one drug for an individual patient. The observer recorded the nature, location, and cost of the drugs ordered, as well as the time to process the order. The time and type of interruptions also were noted. The time to process a drug order was classified as six dependent variables: (1) total time, (2) work time, (3) check time, (4) waiting time I--time from arrival on the dumbwaiter until work was initiated, (5) waiting time II--time between completion of the work and initiation of checking, and (6) waiting time III--time after the check was completed until the order left on the dumbwaiter. The significant predictors of each of the six dependent variables were determined using stepwise multiple regression. The total time to process a prescription order was 58.33 +/- 48.72 minutes; the urgency status of the order was the only significant determinant of total time. Urgency status also significantly predicted the three waiting-time variables. Interruptions and the number of drugs on the order were significant determinants of work time and check time. Each telephone interruption increased the work time by 1.72 minutes. While the results of this study cannot be generalized to other institutions, pharmacy managers can use the method of determining factors that affect medication-order processing time to identify problem areas in their institutions.

    Full Text Available Abstract Background Little is known about the neurobiological foundations of psychotherapy for Posttraumatic Stress Disorder (PTSD. Prior studies have shown that PTSD is associated with altered processing of threatening and aversive stimuli. It remains unclear whether this functional abnormality can be changed by psychotherapy. This is the first randomized controlled treatment trial that examines whether narrative exposure therapy (NET causes changes in affective stimulus processing in patients with chronic PTSD. Methods 34 refugees with PTSD were randomly assigned to a NET group or to a waitlist control (WLC group. At pre-test and at four-months follow-up, the diagnostics included the assessment of clinical variables and measurements of neuromagnetic oscillatory brain activity (steady-state visual evoked fields, ssVEF resulting from exposure to aversive pictures compared to neutral pictures. Results PTSD as well as depressive symptom severity scores declined in the NET group, whereas symptoms persisted in the WLC group. Only in the NET group, parietal and occipital activity towards threatening pictures increased significantly after therapy. Conclusions Our results indicate that NET causes an increase of activity associated with cortical top-down regulation of attention towards aversive pictures. The increase of attention allocation to potential threat cues might allow treated patients to re-appraise the actual danger of the current situation and, thereby, reducing PTSD symptoms.

    Narrative skill in kindergarteners has been shown to be a reliable predictor of later reading comprehension and school achievement. However, we know little about how to scaffold children’s narrative skill. Here we examine whether the quality of kindergarten children’s narrative retellings depends on the kind of narrative elicitation they are given. We asked this question in typically developing (TD) kindergarten children and in children with pre- or perinatal unilateral brain injury (PL), a group that has been shown to have difficulty with narrative production. We compared children’s skill in story retellings under four different elicitation formats: (1) wordless cartoons, (2) stories told by a narrator through the auditory modality, (3) stories told by a narrator through the audiovisual modality without co-speech gestures, and (4) stories told by a narrator in the audiovisual modality with co-speech gestures. We found that children told better structured narratives in the fourth, audiovisual + gesture elicitation format than in the other three elicitation formats, consistent with findings that co-speech gestures can scaffold other aspects of language and memory. The audiovisual + gesture elicitation format was particularly beneficial to children who had the most difficulty telling a well-structured narrative, a group that included children with larger lesions associated with cerebrovascular infarcts.

  2. Emotional and cognitive processing of narratives and individual appraisal styles: recruitment of cognitive control networks vs. modulation of deactivations

    2012-08-01

    Full Text Available Research in psychotherapy has shown that the frequency of use of specific classes of words (such as terms with emotional valence in descriptions of scenes of affective relevance is a possible indicator of psychological affective functioning. Using functional magnetic resonance imaging, we investigated the neural correlates of these linguistic markers in narrative texts depicting core aspects of emotional experience in human interaction, and their modulation by individual differences in the propensity to use these markers. Emotional words activated both lateral and medial aspects of the prefrontal cortex, as in previous studies of instructed emotion regulation and in consistence with recruitment of effortful control processes. However, individual differences in the spontaneous use of emotional terms in characterizing the stimulus material were prevalently associated with modulation of the signal in the perigenual cortex, in the retrosplenial cortex and precuneus, and the anterior insula/ventrolateral prefrontal cortex. Modulation of signal by the presence of these textual markers or individual differences mostly involved areas deactivated by the main task, thus further differentiating neural correlates of these appraisal styles from those associated with effortful control. These findings are discussed in the context of reports in the literature of modulations of deactivations, which suggest their importance in orienting attention and generation of response in the presence of emotional information. These findings suggest that deactivations may play a functional role in emotional appraisal and may contribute to characterizing different appraisal styles.

    Digital storytelling (DST) engages participants in a group-based process to create and share narrative accounts of life events. The process of individuals telling their own stories has not been well assessed as a mechanism of health behavior change. This study looks at outcomes associated with engaging in the DST process for vulnerable youth. The project focused on the experiences of Puerto Rican Latinas between the ages of 15 to 21. A total of 30 participants enrolled in a 4-day DST workshops, with 29 completing a 1 to 3-minute digital story. Self-reported data on several scales (self-esteem, social support, empowerment, and sexual attitudes and behaviors) were collected and analyzed. Participants showed an increase in positive social interactions from baseline to 3-month post workshop. Participants also demonstrated increases in optimism and control over the future immediately after the workshop, but this change was not sustained at 3 months. Analysis of qualitative results and implications are discussed. © The Author(s) 2016.

    The ability to store, integrate, and manipulate information declines with aging. These changes occur earlier, faster, and to a greater degree as a result of neurodegeneration. One of the most common and early characteristics of cognitive decline is difficulty with comprehension of information. The neural mechanisms underlying this breakdown of information processing are poorly understood. Using functional MRI and natural stimuli (e.g., stories), we mapped the neural mechanisms by which the human brain accumulates and processes information with increasing duration and complexity in participants with amnestic mild cognitive impairment (aMCI) and healthy older adults. To explore the mechanisms of information processing, we measured the reliability of brain responses elicited by listening to different versions of a narrated story created by segmenting the story into words, sentences, and paragraphs and then scrambling the segments. Comparing healthy older adults and participants with aMCI revealed that in both groups, all types of stimuli similarly recruited primary auditory areas. However, prominent differences between groups were found at the level of processing long and complex stimuli. In healthy older adults, parietal and frontal regions demonstrated highly synchronized responses in both the paragraph and full story conditions, as has been previously reported in young adults. Participants with aMCI, however, exhibited a robust functional shift of long time scale processing to the pre- and post-central sulci. Our results suggest that participants with aMCI experienced a functional shift of higher order auditory information processing, possibly reflecting a functional response to concurrent or impending neuronal or synaptic loss. This observation might assist in understanding mechanisms of cognitive decline in aMCI.

  10. Narrative and Institutional Economics

    2017-12-01

    Full Text Available This article addresses a range of questions associated with the occurrence of a new field of study – narrative economics, which is considered in the context of modern institutionalism. Pioneering works of R. Shiller, G. Akerlof and D. Snower spotlighted the importance of analyzing narratives and narrative influence when studying economic processes. In this paper, a qualitative study of narratives is seen through the prism of an answer to the question: «How do prescribed narratives influence institutions and change them? ». Narratives have much in common with institutions since very often, explicitly or implicitly, they contain value judgements about social interactions or normative aspects shaping behavioral patterns. The identification of dominating narratives enables us to understand better how institutions influence economic (social action. Repeated interactions among social actors are structured through understanding and learning the rules. Understanding of social rules comes from the language – we articulate and perceive the rules drawing on common narratives. Narratives and institutions are helpful when actors gain knowledge about various forms of social communication. Digital technologies, mass media and social networking sites facilitate the spread of narratives, values and beliefs; this process is characterized by increasing returns. Studying narratives and institutions is crucial for modern economic theory because it helps to improve qualitative and quantitative methods of analyzing empirical evidence and enables researchers to understand complex economic processes.

    The aim of this theoretical article is to elaborate on the underpinning of Norwegian psychomotor physiotherapy (NPMP). With a narrative and hermeneutic point of departure, we explore the unfolding of a 10-year-long treatment by analysing a particular narrative from this treatment context in relation to some foundational perspectives on movement, sensation and time. A woman in her late thirties suffering from muscular tensions and pain, depression, anxiety and anorexia, came for NPMP. The investigation of her treatment experience is based on the journal written by her physiotherapist and first author of this article. We suggest that new experiences in movement and sensation as well as changes in movement patterns can contribute to retuning in sensation and restructuring of narrative time. Feeding the fictional space and narrative fantasy with new experiences in movement and sensation can help counteracting delusional ideas and assist changes, supporting embodied narrative identity. Ingrid's experience is discussed in the light of Trygve Braatøy's understanding of muscular functions, Knud E Løgstrup's phenomenology of sensation and Paul Ricouer's narrative time. © 2012 The Authors.

    Full Text Available Mark Bowden’s hypertext Blackhawk Down (1997 is a paradigmatic example of literary journalism. In this essay, I shall demonstrate that the performative power of Bowden’s hypertext is erected upon a number of textual signals that can be rendered intelligible with the help of analytical tools provided by narratology. I seek to shed light on the genre- and media-specific structures that serve as ways of cultural worldmaking as well as the ethical and epistemological functions of narratological categories that Bowden uses in order to advance narration so that it becomes a process of relating. The most urgent need in the context of a Critical Ethical Narratology (CEN is to find a way to talk about the formal properties of hybridized (fictual genres and to combine this discussion with a consideration of their ideological and ethical implications. The analytical framework of CEN promises to give insights into literary journalism as a genre that is heavily involved in the representation, construction and dissemination of ethical values and norms.

    Clinical nursing process recording (CNPR) has been shown to be an effective tool for facilitating student-centered teaching and learning in nursing education. Yet, the essence and process of this tool have yet to be sufficiently explored and clarified. To explore the essence of CNPR in the contexts of clinical teaching and learning. Reflective analysis was used as the phenomenological approach to analyze the qualitative data, which were transcribed from the oral responses of the six participants who were attending the Clinical Nursing Education Forum. A total of five sessions of the Clinical Nursing Education Forums were conducted. The content of the Clinical Nursing Education Forums consisted of a series of 12 narrative writings of CNPR that were written by a senior student and read and commented on by the student's clinical instructor. Three groups of the essence and process of clinical teaching and learning were inductively identified as: (a) mobilizing autonomous, self-directed learning behavior from self-writing and re-storying; (b) establishing the student-instructor dialogical relationship from mutual localization; and (c) co-creating a learning environment in education and in clinical practice. When used as an interactive teaching and learning tool, CNPR promotes mutual understanding by re-locating the self in the coexisting roles of student nurse, instructor, and patient in a series of nursing care situations. This re-location facilitates students' self-directed learning, enhances the abilities of asking question, waiting for and accompany with the instructor; and promotes the self-care capabilities of patients.

    Virtual patients (VPs) are narrative-based educational activities to train clinical reasoning in a safe environment. Our aim was to explore the influence of the design of the narrative and level of difficulty on the clinical reasoning process, diagnostic accuracy and time-on-task. In a randomized controlled trial, we analyzed the clinical reasoning process of 46 medical students with six VPs in three different variations: (1) patients showing a friendly behavior, (2) patients showing a disruptive behavior and (3) a version without a patient story. For easy VPs, we did not see a significant difference in diagnostic accuracy. For difficult VPs, the diagnostic accuracy was significantly higher for participants who worked on the friendly VPs compared to the other two groups. Independent from VP difficulty, participants identified significantly more problems and tests for disruptive than for friendly VPs; time on task was comparable for these two groups. The extrinsic motivation of participants working on the VPs without a patient story was significantly lower than for the students working on the friendly VPs. Our results indicate that the measured VP difficulty has a higher influence on the clinical reasoning process and diagnostic accuracy than the variations in the narratives.

    2013-01-01

    This study examined the effects of positive affect on working memory (WM) and short-term memory (STM). Given that WM involves both storage and controlled processing and that STM primarily involves storage processing, we hypothesised that if positive affect facilitates controlled processing, it should improve WM more than STM. The results demonstrated that positive affect, compared with neutral affect, significantly enhanced WM, as measured by the operation span task. The influence of positive affect on STM, however, was weaker. These results suggest that positive affect enhances WM, a task that involves controlled processing, not just storage processing. Additional analyses of recall and processing times and accuracy further suggest that improved WM under positive affect is not attributable to motivational differences, but results instead from improved controlled cognitive processing.

    Characteristics of host rocks, secondary minerals, and fluids would affect the transport of radionuclides from a previously proposed repository at Yucca Mountain, Nevada. Minerals in the Yucca Mountain tuffs that are important for retarding radionuclides include clinoptilolite and mordenite (zeolites), clay minerals, and iron and manganese oxides and hydroxides. Water compositions along flow paths beneath Yucca Mountain are controlled by dissolution reactions, silica and calcite precipitation, and ion-exchange reactions. Radionuclide concentrations along flow paths from a repository could be limited by (1) low waste-form dissolution rates, (2) low radionuclide solubility, and (3) radionuclide sorption onto geological media.

    Patients' narratives about traumatic experiences and symptoms are useful in clinical screening and diagnostic procedures. In this study, we presented an automated assessment system to screen patients for posttraumatic stress disorder via a natural language processing and text-mining approach. Four machine-learning algorithms-including decision tree, naive Bayes, support vector machine, and an alternative classification approach called the product score model-were used in combination with n-gram representation models to identify patterns between verbal features in self-narratives and psychiatric diagnoses. With our sample, the product score model with unigrams attained the highest prediction accuracy when compared with practitioners' diagnoses. The addition of multigrams contributed most to balancing the metrics of sensitivity and specificity. This article also demonstrates that text mining is a promising approach for analyzing patients' self-expression behavior, thus helping clinicians identify potential patients from an early stage.

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

Strategic narratives are conceived of as stories with a political purpose or narratives used by political actors to affect the behavior of others. The articles in this issue address two significant areas important to the study of international relations: how strategic narratives support or undermine alliances, and how they affect norm formation and contestation. Within a post-Cold War world and in the midst of a changing media environment, strategic narratives affect how the world and its complex issues are understood. This special issue speaks to the difficulties associated with creating creative and committed international cooperation by noting how strategic narratives are working to shape the Post-Cold War international context.

    Political communications in the form of unstructured text convey rich connotative meaning that can reveal underlying group social processes. Previous research has focused on sentiment analysis at the document level, but we extend this analysis to sub-document levels through a detailed analysis of affective relationships between entities extracted from a document. Instead of pure sentiment analysis, which is just positive or negative, we explore nuances of affective meaning in 22 affect categories. Our affect propagation algorithm automatically calculates and displays extracted affective relationships among entities in graphical form in our prototype (TEAMSTER), starting with seed lists of affect terms. Several useful metrics are defined to infer underlying group processes by aggregating affective relationships discovered in a text. Our approach has been validated with annotated documents from the MPQA corpus, achieving a performance gain of 74% over comparable random guessers.

  11. Narrativity and enaction: the social nature of literary narrative understanding.

    Popova, Yanna B

    2014-01-01

    This paper proposes an understanding of literary narrative as a form of social cognition and situates the study of such narratives in relation to the new comprehensive approach to human cognition, enaction. The particular form of enactive cognition that narrative understanding is proposed to depend on is that of participatory sense-making, as developed in the work of Di Paolo and De Jaegher. Currently there is no consensus as to what makes a good literary narrative, how it is understood, and why it plays such an irreplaceable role in human experience. The proposal thus identifies a gap in the existing research on narrative by describing narrative as a form of intersubjective process of sense-making between two agents, a teller and a reader. It argues that making sense of narrative literature is an interactional process of co-constructing a story-world with a narrator. Such an understanding of narrative makes a decisive break with both text-centered approaches that have dominated both structuralist and early cognitivist study of narrative, as well as pragmatic communicative ones that view narrative as a form of linguistic implicature. The interactive experience that narrative affords and necessitates at the same time, I argue, serves to highlight the active yet cooperative and communal nature of human sociality, expressed in the many forms than human beings interact in, including literary ones.

    The relationship between oral language and the writing process at early acquisition stages and the ways the former can enhance or limit the latter has not been researched extensively. The predictive relationship between kindergarten oral narrative competence and the first- and second-grade written narrative competence was explored in a 3-year longitudinal study. Among the first and second graders, the relationship between orthographic competence and narrative competence in written productions was also analysed. One hundred and nine Italian children participated in this study. Kindergarteners produced an oral narrative, whereas the first and second graders produced a written narrative. The oral and written narratives were analysed in terms of cohesion, coherence, and structure. The first-grade orthographic competence was assessed via a dictation task. Multiple linear regression and mediational analyses were performed.

    Despite evolutionary claims about the function of facial behaviors across phylogeny, rarely are those hypotheses tested in a comparative context-that is, by evaluating how nonhuman animals process such behaviors. Further, while increasing evidence indicates that humans make meaning of faces by integrating contextual information, including that from the body, the extent to which nonhuman animals process contextual information during affective displays is unknown. In the present study, we evaluated the extent to which rhesus macaques (Macaca mulatta) process dynamic affective displays of conspecifics that included both facial and body behaviors. Contrary to hypotheses that they would preferentially attend to faces during affective displays, monkeys looked for longest, most frequently, and first at conspecifics' bodies rather than their heads. These findings indicate that macaques, like humans, attend to available contextual information during the processing of affective displays, and that the body may also be providing unique information about affective states.

    on a distinction between history and narrative, I outline an account of historical becoming through a process of sedimentation and a rich notion of what I call historical selfhood on an embodied level. Five embodied existentials are suggested, sketching a preliminary understanding of how selves are concretely......Narrative theories currently dominate our understanding of how selfhood is constituted and concretely individuated throughout personal history. Despite this success, the narrative perspective has recently been exposed to a range of critiques. Whilst these critiques have been effective in pointing...... out the shortcomings of narrative theories of selfhood, they have been less willing and able to suggest alternative ways of understanding personal history. In this article, I assess the criticisms and argue that an adequate phenomenology of personal history must also go beyond narrative. Drawing...

    Full Text Available “Chick lit” has become more and more popular in recent years, and the portrayed female’s power and subjectivity have stirred many debates and been centered as controversial issues. Focusing on two films of this genre, this study firstly undertook narrative analysis to understand how in the storylines women just entering the workplaces could overcome a wide variety of challenges, and then performed in-depth interviews to explore how young female audiences interpreted the films. The study found that both movies presented conflicts within and between love life and workplace relationship in the kernel events. Regarding these conflicts portrayed, interviewed audiences, on one hand, thought that work and love life both should get well balanced, echoing social expectations for women, while on the other hand, recognized and appreciated the successful career women’s characteristics owned by the heroines, and pointed out that the films equipped females with the power to accomplish their dreams.

    Narrative coaching is representative of the new wave – or third generation – of coaching practice . The theory and practice of narrative coaching takes into account the social and cultural conditions of late modern society, and must be seen as intertwined with them. Some initial conceptualizations...... of narrative coaching were developed by David Drake (2006, 2007, 2008, 2009) in the USA and Australia, by Ho Law in the UK (Law, 2007a + b; Law & Stelter, 2009) and by Reinhard Stelter (2007, 2009, 2012, in preparation; Stelter & Law, 2010) in Denmark.

    2013-12-01

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

    Drukteinis, Albert M

    2014-01-01

    Psychiatrists function, in part, as historians who rely on patient narratives to help them understand presenting mental disorders and explain their causes. Forensic psychiatrists have been skeptical of using narratives, raising concerns about their lack of objectivity and potential for bias. They also have criticized narratives as being more performative than scientific. Recent authors, however, have pointed out that narratives may be helpful in forming forensic opinions and supporting oral testimony, while stressing that their use must be consistent with the ethics espoused by forensic psychiatry. This article reviews the role of narratives in understanding human events and the ubiquitous presence of narratives in the judicial process. It delves into the inescapability of using explicit or implicit narratives in the course of forensic practice, as well as how they may be meaningfully incorporated into evaluations and find expression alongside scientific principles. © 2014 American Academy of Psychiatry and the Law.

  5. Narrative research in psychotherapy: a critical review.

    Avdi, Evrinomy; Georgaca, Eugenie

    2007-09-01

    This paper is a review of studies which utilise the notion of narrative to analyse psychotherapy. Its purpose is to systematically present this diverse field of research, to highlight common themes and divergences between different strands and to further the development and integration of narrative research in psychotherapy. The paper reviews studies which employ an applied textual analysis of narratives produced in the context of psychotherapy. Criteria for inclusion of studies are, firstly, the analysis of therapeutic and therapy-related texts and, secondly, the adoption of a narrative psychological perspective. The studies were examined on the basis of the notion of narrative they employ and the aspects of client narratives they focus on, and were grouped accordingly in the review. The majority of the studies reviewed assume a constructivist approach to narrative, adopt a representational view of language, focus primarily on client micro-narratives and relate to cognitive-constructivist and process-experiential psychotherapeutic approaches. A smaller group of studies assume a social constructionist approach to narrative and a functional view of language, focus on micro-narratives, highlight the interactional and wider social aspects of narrative and relate to postmodern trends in psychotherapy. The range of conceptualisations of narrative in the studies reviewed, from a representational psychological view to a constructionist social view, reflects tensions within narrative psychology itself. Moreover, two trends can be discerned in the field reviewed, narrative analysis of therapy, which draws from narrative theory and utilises the analytic approaches of narrative research to study psychotherapy, and analyses of narrative in therapy, which study client narratives using non-narrative qualitative methods. Finally, the paper highlights the need for integration of this diverse field of research and urges for the development of narrative studies of psychotherapy

  6. Factors affecting the periapical healing process of endodontically treated teeth

    Roberto Holland

    Full Text Available Abstract Tissue repair is an essential process that reestablishes tissue integrity and regular function. Nevertheless, different therapeutic factors and clinical conditions may interfere in this process of periapical healing. This review aims to discuss the important therapeutic factors associated with the clinical protocol used during root canal treatment and to highlight the systemic conditions associated with the periapical healing process of endodontically treated teeth. The antibacterial strategies indicated in the conventional treatment of an inflamed and infected pulp and the modulation of the host's immune response may assist in tissue repair, if wound healing has been hindered by infection. Systemic conditions, such as diabetes mellitus and hypertension, can also inhibit wound healing. The success of root canal treatment is affected by the correct choice of clinical protocol. These factors are dependent on the sanitization process (instrumentation, irrigant solution, irrigating strategies, and intracanal dressing, the apical limit of the root canal preparation and obturation, and the quality of the sealer. The challenges affecting the healing process of endodontically treated teeth include control of the inflammation of pulp or infectious processes and simultaneous neutralization of unpredictable provocations to the periapical tissue. Along with these factors, one must understand the local and general clinical conditions (systemic health of the patient that affect the outcome of root canal treatment prediction.

    A parallel factor analysis (PARAFAC) of oil sands process-affected water was presented. Naphthenic acids (NA) are traditionally described as monobasic carboxylic acids. Research has indicated that oil sands NA do not fit classical definitions of NA. Oil sands organic acids have toxic and corrosive properties. When analyzed by fluorescence technology, oil sands process-affected water displays a characteristic peak at 290 nm excitation and approximately 346 nm emission. In this study, a parallel factor analysis (PARAFAC) was used to decompose process-affected water multi-way data into components representing analytes, chemical compounds, and groups of compounds. Water samples from various oil sands operations were analyzed in order to obtain EEMs. The EEMs were then arranged into a large matrix in decreasing process-affected water content for PARAFAC. Data were divided into 5 components. A comparison with commercially prepared NA samples suggested that oil sands NA is fundamentally different. Further research is needed to determine what each of the 5 components represent. tabs., figs.

    Methamphetamine abuse is associated with high rates of aggression but few studies have addressed the contributing neurobiological factors. To quantify aggression, investigate function in the amygdala and prefrontal cortex, and assess relationships between brain function and behavior in methamphetamine-dependent individuals. In a case-control study, aggression and brain activation were compared between methamphetamine-dependent and control participants. Participants were recruited from the general community to an academic research center. Thirty-nine methamphetamine-dependent volunteers (16 women) who were abstinent for 7 to 10 days and 37 drug-free control volunteers (18 women) participated in the study; subsets completed self-report and behavioral measures. Functional magnetic resonance imaging (fMRI) was performed on 25 methamphetamine-dependent and 23 control participants. We measured self-reported and perpetrated aggression and self-reported alexithymia. Brain activation was assessed using fMRI during visual processing of facial affect (affect matching) and symbolic processing (affect labeling), the latter representing an incidental form of emotion regulation. Methamphetamine-dependent participants self-reported more aggression and alexithymia than control participants and escalated perpetrated aggression more following provocation. Alexithymia scores correlated with measures of aggression. During affect matching, fMRI showed no differences between groups in amygdala activation but found lower activation in methamphetamine-dependent than control participants in the bilateral ventral inferior frontal gyrus. During affect labeling, participants recruited the dorsal inferior frontal gyrus and exhibited decreased amygdala activity, consistent with successful emotion regulation; there was no group difference in this effect. The magnitude of decrease in amygdala activity during affect labeling correlated inversely with self-reported aggression in control participants

    Primary care behavioral health (PCBH) is a population-based approach to delivering mental and behavioral health care in the primary care setting. Implementation of the PCBH model varies across practice settings, which can impact how PCBH providers deliver services to patients and in turn may predict a variety of important outcomes. This article aims to characterize PCBH provider engagement in key processes of integrated care as demonstrated in results from empirical studies of real-world clinical practice. For this narrative review of published studies on PCBH provider engagement in processes of care, PubMed and PsycINFO databases were searched from January 1990 through May 2016 to identify relevant articles. Provider adherence to the brief, time-limited treatment model appears suboptimal. Common mental health conditions, such as depression, were often the primary focus of provider attention, with less consistent emphasis on behavioral medicine concerns. Whereas providers regularly conducted qualitative functional assessments with patients, routine use of standardized measures was low. Engagement in interprofessional collaboration with the primary care team was also low, but engagement in behaviors that fostered therapeutic relationships was high. This review identified several strengths and weaknesses of typical PCBH provider practices. Results are discussed in relation to their value as areas for future quality improvement initiatives that can improve PCBH service delivery and, ultimately, patient outcomes.

    2016-04-01

    Full Text Available Narrative is one of many qualitative methodologies that can be brought to bear in collecting and analysing data and reporting results, though it is not as frequently used as say in case studies. This article provides a window into its use, from the perspective of a researcher who has used it consistently over the past decade to examine early career researcher experience – doctoral students, and those who have completed their degrees and are advancing their careers. This experience has contributed to a robust understanding of the potential of narrative, as well as its limitations. This paper first lays out the broad landscape of narrative research and then makes transparent the thinking, processes and procedures involved in the ten-year narrative study including the potential for creativity that narrative invites. The goal is to engage other researchers to consider exploring the use of narrative – if it aligns with their epistemological stance.

    Habermas, Tilmann; Meier, Michaela; Mukhtar, Barbara

    2009-12-01

    Two studies test the assertion that anger, sadness, fear, pride, and happiness are typically narrated in different ways. Everyday events eliciting these 5 emotions were narrated by young women (Study 1) and 5- and 8-year-old girls (Study 2). Negative narratives were expected to engender more effort to process the event, be longer, more grammatically complex, more often have a complication section, and use more specific emotion labels than global evaluations. Narratives of Hogan's (2003) juncture emotions anger and fear were expected to focus more on action and to contain more core narrative sections of orientation, complication, and resolution than narratives of the outcome emotions sadness and happiness. Hypotheses were confirmed for adults except for syntactic complexity, whereas children showed only some of these differences. Hogan's theory that juncture emotions are restricted to the complication section was not confirmed. Finally, in adults, indirect speech was more frequent in anger narratives and internal monologue in fear narratives. It is concluded that different emotions should be studied in how they are narrated, and that narratives should be analyzed according to qualitatively different emotions.

  20. Electrophysiological differences in the processing of affect misattribution.

    Directory of Open Access Journals (Sweden)

    Yohei Hashimoto

    Full Text Available The affect misattribution procedure (AMP was proposed as a technique to measure an implicit attitude to a prime image [1]. In the AMP, neutral symbols (e.g., a Chinese pictograph, called the target are presented, following an emotional stimulus (known as the prime. Participants often misattribute the positive or negative affect of the priming images to the targets in spite of receiving an instruction to ignore the primes. The AMP effect has been investigated using behavioral measures; however, it is difficult to identify when the AMP effect occurs in emotional processing-whether the effect may occur in the earlier attention allocation stage or in the later evaluation stage. In this study, we examined the neural correlates of affect misattribution, using event-related potential (ERP dividing the participants into two groups based on their tendency toward affect misattribution. The ERP results showed that the amplitude of P2 was larger for the prime at the parietal location in participants showing a low tendency to misattribution than for those showing a high tendency, while the effect of judging neutral targets amiss according to the primes was reflected in the late processing of targets (LPP. In addition, the topographic pattern analysis revealed that EPN-like component to targets was correlated with the difference of AMP tendency as well as P2 to primes and LPP to targets. Taken together, the mechanism of the affective misattribution was closely related to the attention allocation processing. Our findings provide neural evidence that evaluations of neutral targets are misattributed to emotional primes.

    2016-08-01

    There has been growing interest in the role that implicit processing of drug cues can play in motivating drug use behavior. However, the extent to which drug cue processing biases relate to the processing biases exhibited to other types of evocative stimuli is largely unknown. The goal of the present study was to determine how the implicit cognitive processing of smoking cues relates to the processing of affective cues using a novel paradigm. Smokers (n = 50) and nonsmokers (n = 38) completed a picture-viewing task, in which participants were presented with a series of smoking, pleasant, unpleasant, and neutral images while engaging in a distractor task designed to direct controlled resources away from conscious processing of image content. Electroencephalogram recordings were obtained throughout the task for extraction of event-related potentials (ERPs). Smokers exhibited differential processing of smoking cues across 3 different ERP indices compared with nonsmokers. Comparable effects were found for pleasant cues on 2 of these indices. Late cognitive processing of smoking and pleasant cues was associated with nicotine dependence and cigarette use. Results suggest that cognitive biases may extend across classes of stimuli among smokers. This raises important questions about the fundamental meaning of cognitive biases, and suggests the need to consider generalized cognitive biases in theories of drug use behavior and interventions based on cognitive bias modification.

    Purpose Returning to work is a process that is intertwined with the social aspects of one's life, which can influence the way in which that person manages their return to work and also determines the support available to them. This study aimed to explore cancer patients' perceptions of the role of their social context in relation to returning to work following treatment. Methods Twenty-three patients who had received a diagnosis of either urological, breast, gynaecological, or bowel cancer participated in semi-structured interviews examining general perceptions of cancer, work values and perceptions of the potential impact of their cancer diagnosis and treatment on work. Interviews were analysed using the iterative process of Framework Analysis. Results Two superordinate themes emerged as influential in the return to work process: Social support as a facilitator of return to work (e.g. co-workers' support and support outside of the workplace) and Social comparison as an appraisal of readiness to return to work (e.g. comparisons with other cancer patients, colleagues, and employees in other organisations or professions). Conclusions Two functions of the social context of returning to work after cancer were apparent in the participants' narrative: the importance of social support as a facilitator of returning to work and the utilisation of social comparison information in order to appraise one's readiness to return to work. The role of social context in returning to work has largely been absent from the research literature to date. The findings of this study suggest that social support and social comparison mechanisms may have a significant impact on an individual's successful return to the workplace.

  6. Framing in Entertainment-Education: Effects on Processes of Narrative Persuasion.

    2017-12-01

    Nowadays, entertainment-education (E-E) is often used as a persuasive strategy to stimulate prosocial behavior. Although E-E is mostly regarded as a persuasive strategy in itself, in an increasing number of E-E programs several persuasive strategies are used to communicate the educational message to the audience. This study investigates the effects of a strategy widely used in health communication, but not previously studied in the field of E-E: framing. To this means we examined the effect of two different ways an E-E message can be framed: by emphasizing either the losses of not performing the behavior in question or the gains of performing this behavior. A serial multiple mediation model showed that framing affected intention to refrain from drunk cycling via counterarguing and attitude toward drunk cycling; the use of a gain frame decreased counterarguing, which decreased the attitude toward drunk cycling. This subsequently resulted in a higher intention to refrain from this behavior. Implications of these results are discussed.

    This article presents the main results from a large-scale analytical systematic review on knowledge exchange interventions at the organizational and policymaking levels. The review integrated two broad traditions, one roughly focused on the use of social science research results and the other focused on policymaking and lobbying processes. Data collection was done using systematic snowball sampling. First, we used prospective snowballing to identify all documents citing any of a set of thirty-three seminal papers. This process identified 4,102 documents, 102 of which were retained for in-depth analysis. The bibliographies of these 102 documents were merged and used to identify retrospectively all articles cited five times or more and all books cited seven times or more. All together, 205 documents were analyzed. To develop an integrated model, the data were synthesized using an analytical approach. This article developed integrated conceptualizations of the forms of collective knowledge exchange systems, the nature of the knowledge exchanged, and the definition of collective-level use. This literature synthesis is organized around three dimensions of context: level of polarization (politics), cost-sharing equilibrium (economics), and institutionalized structures of communication (social structuring). The model developed here suggests that research is unlikely to provide context-independent evidence for the intrinsic efficacy of knowledge exchange strategies. To design a knowledge exchange intervention to maximize knowledge use, a detailed analysis of the context could use the kind of framework developed here. © 2010 Milbank Memorial Fund.

    Pérez-Poch, A.; Bru, C.; Nicolau, C.

    The purpose of this study was to evaluate diffuse affectations in the liver using texture image processing techniques. Ultrasound diagnose equipments are the election of choice to be used in space environments as they are free from hazardous effects on health. However, due to the need for highly trained radiologists to assess the images, this imaging method is mainly applied on focal lesions rather than on non-focal ones. We have conducted a clinical study on 72 patients with different degrees of chronic hepatopaties and a group of control of 18 individuals. All subjects' clinical reports and results of biopsies were compared to the degree of affectation calculated by our computer system , thus validating the method. Full statistical results are given in the present paper showing a good correlation (r=0.61) between pathologist's report and analysis of the heterogenicity of the processed images from the liver. This computer system to analyze diffuse affectations may be used in-situ or via telemedicine to the ground.

    Despite social cognitive dysfunction that may be observed in patients with schizophrenia, the knowledge about social and nonsocial affective processing in schizophrenia is scant. The aim of this study was to examine neurophysiological and behavioural responses to neutral and negative stimuli with (faces, people) and without (animals, objects) social content in schizophrenia. Twenty-six patients with schizophrenia (SCZ) and 21 healthy controls (HC) completed a visual oddball paradigm with either negative or neutral pictures from the Nencki Affective Picture System (NAPS) as targets while EEG was recorded. Half of the stimuli within each category presented social content (faces, people). Negative stimuli with social content produced lower N2 amplitude and higher mean LPP than any other type of stimuli in both groups. Despite differences in behavioural ratings and alterations in ERP processing of affective stimuli (lack of EPN differentiation, decreased P3 to neutral stimuli) SCZ were still able to respond to specific categories of stimuli similarly to HC. The pattern of results suggests that with no additional emotion-related task demands patients with schizophrenia may present similar attentional engagement with negative social stimuli as healthy controls.

    This paper presents the results obtained by the public utilities corporation (PUC), within the framework of an IAEA TC project, which aims to evaluate the potential of the la digue aquifer. Several monitoring activities and hydrochemical and isotopic surveys have been conducted. Results indicate the presence of brackish water at shallow depths, and low redox potentials, attesting to the presence of H{sub 2}S and heavy metals. Groundwater quality is affected by the concomitant presence of different adverse factors, namely aquifer characteristics, hydrogeology, and anthropogenic pressure. In addition, seawater penetrates the river course during high tides and infiltrates through the recharge area of the aquifer that is close to the actual pumping station. The positioning of non return high tide gates, an easy and low cost intervention, could enhance groundwater quality. The understanding of the main processes affecting groundwater quality helped in the identification of areas favourable for new wells, located at higher elevations. (author)

    Whether contextual regularities facilitate perceptual stages of scene processing is widely debated, and empirical evidence is still inconclusive. Specifically, it was recently suggested that contextual violations affect early processing of a scene only when the incongruent object and the scene are presented a-synchronously, creating expectations. We compared event-related potentials (ERPs) evoked by scenes that depicted a person performing an action using either a congruent or an incongruent object (e.g., a man shaving with a razor or with a fork) when scene and object were presented simultaneously. We also explored the role of attention in contextual processing by using a pre-cue to direct subjects׳ attention towards or away from the congruent/incongruent object. Subjects׳ task was to determine how many hands the person in the picture used in order to perform the action. We replicated our previous findings of frontocentral negativity for incongruent scenes that started ~ 210 ms post stimulus presentation, even earlier than previously found. Surprisingly, this incongruency ERP effect was negatively correlated with the reaction times cost on incongruent scenes. The results did not allow us to draw conclusions about the role of attention in detecting the regularity, due to a weak attention manipulation. By replicating the 200-300 ms incongruity effect with a new group of subjects at even earlier latencies than previously reported, the results strengthen the evidence for contextual processing during this time window even when simultaneous presentation of the scene and object prevent the formation of prior expectations. We discuss possible methodological limitations that may account for previous failures to find this an effect, and conclude that contextual information affects object model selection processes prior to full object identification, with semantic knowledge activation stages unfolding only later on.

    This commentary highlights some of the interesting points to emerge from the preceding papers about the self, social, and directive functions of autobiographical memory. Additionally some cognitive functions are also considered and especially the way in which autobiographical memory supports, constrains, and maintains the goals of the self. Directions for future research into the self, social, directive, and cognitive-affective functions and processes of autobiographical memory are reviewed. Emphasis is placed on future research into the function of autobiographical memory in representations of attachment.

    Highlights: • Mixing of acid riverine water with alkaline seawater was studied in an estuary. • Combination of data and geochemical tools allowed modeling the water mixing. • The main geochemical processes were identified and for the first time quantified. • Water chemistry is the result of mixing, dissolution-precipitation and sorption. • Main reactions: gypsum and calcite dissolution and Al and Fe solids precipitation. - Abstract: This study provides geochemical data with the aim of identifying and quantifying the main processes occurring in an Acid Mine Drainage (AMD) affected estuary. With that purpose, water samples of the Huelva estuary were collected during a tidal half-cycle and ion–ion plots and geochemical modeling were performed to obtain a general conceptual model. Modeling results indicated that the main processes responsible for the hydrochemical evolution of the waters are: (i) the mixing of acid fluvial water with alkaline ocean water; (ii) precipitation of Fe oxyhydroxysulfates (schwertmannite) and hydroxides (ferrihydrite); (iii) precipitation of Al hydroxysulfates (jurbanite) and hydroxides (amorphous Al(OH) 3 ); (iv) dissolution of calcite; and (v) dissolution of gypsum. All these processes, thermodynamically feasible in the light of their calculated saturation states, were quantified by mass-balance calculations and validated by reaction-path calculations. In addition, sorption processes were deduced by the non-conservative behavior of some elements (e.g., Cu and Zn)

    Full Text Available Three experiments demonstrate how the processing of negations is contingent on the evaluation context in which the negative information is presented. In addition, the strategy used to process the negations induced different affective reactions toward the stimuli, leading to inconsistency of preference. Participants were presented with stimuli described by either stating the presence of positive features (explicitly positive alternative or negating the presence of negative features (non-negative alternative. Alternatives were presented for either joint (JE or separate evaluation (SE. Experiment 1 showed that the non-negative stimuli were judged less attractive than the positive ones in JE but not in SE. Experiment 2 revealed that the non-negative stimuli induced a less clear and less positive feeling when they were paired with explicitly positive stimuli rather than evaluated separately. Non-negative options were also found less easy to judge than the positive ones in JE but not in SE. Finally, Experiment 3 showed that people process negations using two different models depending on the evaluation mode. Through a memory task, we found that in JE people process the non-negative attributes as negations of negative features, whereas in SE they directly process the non-negative attributes as positive features.

    Previous research has highlighted brain regions associated with socioemotional processes in persuasive message encoding, whereas cognitive models of persuasion suggest that executive brain areas may also be important. The current study aimed to identify lateral prefrontal brain areas associated with persuasive message viewing and understand how activity in these executive regions might interact with activity in the amygdala and medial pFC. Seventy adolescents were scanned using fMRI while they watched 10 strongly convincing antidrug public service announcements (PSAs), 10 weakly convincing antidrug PSAs, and 10 advertisements (ads) unrelated to drugs. Antidrug PSAs compared with nondrug ads more strongly elicited arousal-related activity in the amygdala and medial pFC. Within antidrug PSAs, those that were prerated as strongly persuasive versus weakly persuasive showed significant differences in arousal-related activity in executive processing areas of the lateral pFC. In support of the notion that persuasiveness involves both affective and executive processes, functional connectivity analyses showed greater coactivation between the lateral pFC and amygdala during PSAs known to be strongly (vs. weakly) convincing. These findings demonstrate that persuasive messages elicit activation in brain regions responsible for both emotional arousal and executive control and represent a crucial step toward a better understanding of the neural processes responsible for persuasion and subsequent behavior change.

    Phytotherapeutic compounds are largely used in the treatment of lower urinary tract symptoms (LUTS) related to benign prostatic hyperplasia (BPH) due to low side-effect profiles and costs, high level of acceptance by patients and a low rate of dropout. Here, we aimed to analyze all available evidence on the role of Cucurbita pepo in the treatment of LUTS-BPH. In May 2016 a systematic search was carried out thorough National Library of Medicine Pubmed, Scopus database and the ISI Web of Knowledge official website in order to identify all published studies on Cucurbita pepo and BPH. The following search strings were used: "Cucurbita pepo" OR "pumpkin seed" AND "prostate"; "Cucurbita pepo" AND "antiandrogen" OR "antiproliferative" OR "anti-inflammatory" OR "antioxidant activities"; "cucurbita pepo" OR "pumpkin seed" AND "LUTS" AND "symptoms improvement" OR "quality of life". We consider for the present analysis only studies related to LUTS-BPH. Among all 670 screened, 16 were related to LUTSBPH and finally analyzed. Among all, ten of them were performed in "in vitro setting" showing anti-inflammatory and antiandrogen effect, and a reduction in prostate growth and detrusor activity, while six were clinical studies. In all studies an improvement in International Prostatic Symptoms Score (IPSS) and uroflowmetry parameters has been reported. In 4 studies, an improvement in quality of life has been reported. On the basis of our narrative review, the use of Cucurbita pepo in the management of patients affected by LUTS-BPH seems to be useful for improving symptoms and quality of life. However, future clinical trials are requested to confirm these promising results.

    2006-07-01

    Full Text Available The aim of this article is to investigate to what extent the belief system of both counsellor and client plays a role in counselling. It is generally accepted that beliefs play a central role in the life of all people. This article applies this notion, as described by, among others, Wright, Watson and Bell (1986, to the field of pastoral care and more specifically to the narrative approach within it. The narrative approach is an important instrument that helps people to understand how their life stories have been shaped by their beliefs about themselves. Throughout the article the researcher attempts to indicate how the counsellor, client and counselling process are influenced by their respective scientific and pre-scientific roots and development, as well as by their system of belief in general.

    Colorectal cancer (CRC) is a preventable yet leading cause of cancer mortality among Latinos in the USA. Cultural targeting and narrative messaging are two strategies to increase the low screening colonoscopy rates among Latinos. This study identifies key messages for educational interventions aiming to increase screening colonoscopy used among Latinos and proposes a model to understand the relationship between factors involved in colonoscopy decision-making. Individual in-depth interviews were conducted with 12 Latino participants primarily of Puerto Rican descent on the topics of CRC knowledge, barriers and facilitators to colonoscopy use, and the use of narrative in colorectal health messaging. Knowledge about colorectal anatomy and the anesthesia component of colonoscopy procedure is low. Fear of procedure-related pain and fear of treatment-related burden following a cancer diagnosis are significant barriers to colonoscopy. Fear of disease-related suffering and death following a cancer diagnosis and fear of regret are strong facilitators and can be augmented by cancer narratives. Storytelling is commonly used in Latino culture and is an acceptable method to educate the Latino community about CRC screening via colonoscopy. Machismo is a unique barrier to colonoscopy for Latino men via homophobia and reluctance to seek healthcare. A preliminary model to understand factors in colonoscopy decision-making among Latinos is presented. Counseling practices and educational interventions that use culturally targeted narrative health messaging to mediate fears and increase colonoscopy knowledge may increase screening colonoscopy use among Latinos.

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

    Reading experimenter-provided narratives of negative income shock has been previously demonstrated to increase impulsivity, as measured by discounting of delayed rewards. We hypothesized that writing these narratives would potentiate their effects of negative income shock on decision-making more than simply reading them. In the current study, 193 cigarette-smoking individuals from Amazon Mechanical Turk were assigned to either read an experimenter-provided narrative or self-generate a narrative describing either the negative income shock of job loss or a neutral condition of job transfer. Individuals then completed a task of delay discounting and measures of affective response to narratives, as well as rating various narrative qualities such as personal relevance and vividness. Consistent with past research, narratives of negative income shock increased delay discounting compared to control narratives. No significant differences existed in delay discounting after self-generating compared to reading experimenter-provided narratives. Positive affect was lower and negative affect was higher in response to narratives of job loss, but affect measures did not differ based on whether narratives were experimenter-provided or self-generated. All narratives were rated as equally realistic, but self-generated narratives (whether negative or neutral) were rated as more vivid and relevant than experimenter-provided narratives. These results indicate that the content of negative income shock narratives, regardless of source, consistently drives short-term choices.

    2016-05-01

    To explain the development and application of storytelling/narrative theory in health disparities intervention research as a way to promote health communication and behavior change among racial, ethnic, and minority populations. The proposed storytelling theory helps explain that storytelling affects changes in attitude and health behavior of the viewer through realism, identification, and transportation. The proposed storytelling/narrative theory can be a guide to develop culturally grounded narrative interventions that have the ability to connect with hard-to-reach populations. Narrative communication is context-dependent because it derives meaning from the surrounding situation and provides situation-based stories that are a pathway to processing story content. Although storytelling is grounded in nursing practice and education, it is underutilized in nursing interventional research. Future efforts are needed to extend theory-based narrative intervention studies designed to change attitude and behaviors that will reduce health disparities among minorities.

  11. Self-defining memories, scripts, and the life story: narrative identity in personality and psychotherapy.

    Science.gov (United States)

    Singer, Jefferson A; Blagov, Pavel; Berry, Meredith; Oost, Kathryn M

    2013-12-01

    An integrative model of narrative identity builds on a dual memory system that draws on episodic memory and a long-term self to generate autobiographical memories. Autobiographical memories related to critical goals in a lifetime period lead to life-story memories, which in turn become self-defining memories when linked to an individual's enduring concerns. Self-defining memories that share repetitive emotion-outcome sequences yield narrative scripts, abstracted templates that filter cognitive-affective processing. The life story is the individual's overarching narrative that provides unity and purpose over the life course. Healthy narrative identity combines memory specificity with adaptive meaning-making to achieve insight and well-being, as demonstrated through a literature review of personality and clinical research, as well as new findings from our own research program. A clinical case study drawing on this narrative identity model is also presented with implications for treatment and research. © 2012 Wiley Periodicals, Inc.

  12. How processing digital elevation models can affect simulated water budgets

    2009-01-01

    For regional models, the shallow water table surface is often used as a source/sink boundary condition, as model grid scale precludes simulation of the water table aquifer. This approach is appropriate when the water table surface is relatively stationary. Since water table surface maps are not readily available, the elevation of the water table used in model cells is estimated via a two-step process. First, a regression equation is developed using existing land and water table elevations from wells in the area. This equation is then used to predict the water table surface for each model cell using land surface elevation available from digital elevation models (DEM). Two methods of processing DEM for estimating the land surface for each cell are commonly used (value nearest the cell centroid or mean value in the cell). This article demonstrates how these two methods of DEM processing can affect the simulated water budget. For the example presented, approximately 20% more total flow through the aquifer system is simulated if the centroid value rather than the mean value is used. This is due to the one-third greater average ground water gradients associated with the centroid value than the mean value. The results will vary depending on the particular model area topography and cell size. The use of the mean DEM value in each model cell will result in a more conservative water budget and is more appropriate because the model cell water table value should be representative of the entire cell area, not the centroid of the model cell.

    Severe fine particulate matter (PM2.5) pollution over North China has received broad attention worldwide in recent years. Better understanding the sources and processes controlling pollution over this region is of great importance with urgent implications for air quality policy. We will present a four-dimensional variational (4D-Var) data assimilation system using the GEOS-Chem chemical transport model and its adjoint model at 0.25° × 0.3125° horizontal resolution, and apply it to analyze the factors affecting PM2.5 concentrations over North China. Hourly surface observations of PM2.5 and sulfur dioxide (SO2) from the China National Environmental Monitoring Center (CNEMC) can be assimilated into the model to evaluate and constrain aerosol (primary and precursors) emissions. Application of the data assimilation system to the APEC period (the Asia-Pacific Economic Cooperation summit; 5-11 November 2014) shows that 46% of the PM2.5 pollution reduction during APEC ("The APEC Blue") can be attributed to meteorology conditions and the rest 54% to emission reductions due to strict emission controls. Ammonia emissions are shown to significantly contribute to PM2.5 over North China in the fall. By converting sulfuric acid and nitric acid to longer-lived ammonium sulfate and ammonium nitrate aerosols, ammonia plays an important role in promoting their regional transport influences.

    A detailed visual processing style has been noted in autism spectrum disorder (ASD); this contributes to problems in face processing and has been directly related to abnormal processing of spatial frequencies (SFs). Little is known about the early development of face processing in ASD and the relation with abnormal SF processing. We investigated whether young ASD children show abnormalities in low spatial frequency (LSF, global) and high spatial frequency (HSF, detailed) processing and explored whether these are crucially involved in the early development of face processing. Three- to 4-year-old children with ASD (n = 22) were compared with developmentally delayed children without ASD (n = 17). Spatial frequency processing was studied by recording visual evoked potentials from visual brain areas while children passively viewed gratings (HSF/LSF). In addition, children watched face stimuli with different expressions, filtered to include only HSF or LSF. Enhanced activity in visual brain areas was found in response to HSF versus LSF information in children with ASD, in contrast to control subjects. Furthermore, facial-expression processing was also primarily driven by detail in ASD. Enhanced visual processing of detailed (HSF) information is present early in ASD and occurs for neutral (gratings), as well as for socially relevant stimuli (facial expressions). These data indicate that there is a general abnormality in visual SF processing in early ASD and are in agreement with suggestions that a fast LSF subcortical face processing route might be affected in ASD. This could suggest that abnormal visual processing is causative in the development of social problems in ASD. Copyright © 2010 Society of Biological Psychiatry. Published by Elsevier Inc.

  19. Politics of love: narrative structures, intertextuality and social agency in the narratives of parents with disabled children.

    Hanisch, Halvor

    2013-11-01

    Recent research has highlighted how parental narratives can be important in the resistance against disabling processes. This article contains analyses of enabling language in narratives published by Scandinavian disability rights organizations. First, drawing on the work of Fisher and Goodley, I point out that the material constitute a threefold: normality narratives, resistance narratives, and narratives that demonstrate an appreciation of the present and the child's individual alterity. Second, I demonstrate that the last narrative draws on Romanticism rather than linguistic resources from disability culture. Third, I show that these narratives are hyperboles - texts that strengthen and emphasise the valuation to the point where the narrative structure transcends narrative consistency. Fourth, drawing on the work of Kristeva, I argue that this form of narration constitutes an intimate politics of love. © 2013 The Author.

    2015-07-01

    Full Text Available Traditional art museum exhibitions are planned according to art-historical elements. At Trapholt – a museum of modern Danish art, design and applied art in Denmark, we are interested in exploring what happens when ordinary visitors are invited to curate personal exhibitions in the museum space. This paper analyses the project The Kaleidoscope of Culture, where people with no art historical background were invited to curate exhibitions based on the Trapholt collection of art and their own cultural backgrounds and experiences. The main argument is that, by allowing these personal voices in the museum space, new museum narratives are established. But to make the museum a truly transformative space the art- historical knowledge and methods must also be activate.

    Full Text Available This article is a proposal of identity research through its process and narrative character. As a starting point I present a definition of identity understood as the whole life process of finding identification. Next I present my own model of auto/biography-narrative research inspired by hermeneutic and phenomenological traditions of thinking about experiencing reality. I treat auto/biography-narrative research as a means of exploratory conduct, based on the narrator’s biography data, also considering the researcher’s autobiographical thought. In the final part of the article I focus on showing the narrative structure of identity and autobiography. I emphasise this relation in definitions qualifying autobiography as written life narration and identity as a narration of autobiography.

    Kurby, Christopher A; Asiala, Lillian K E; Mills, Steven R

    2014-01-01

    The perception of event structure in continuous activity is important for everyday comprehension. Although the segmentation of experience into events is a normal concomitant of perceptual processing, previous research has shown age differences in the ability to perceive structure in naturalistic activity, such as a movie of someone washing a car. However, past research has also shown that older adults have a preserved ability to comprehend events in narrative text, which suggests that narrative may improve the event processing of older adults. This study tested whether there are age differences in event segmentation at the intersection of continuous activity and narrative: narrative film. Younger and older adults watched and segmented a narrative film, The Red Balloon, into coarse and fine events. Changes in situational features, such as changes in characters, goals, and objects predicted segmentation. Analyses revealed little age-difference in segmentation behavior. This suggests the possibility that narrative structure supports event understanding for older adults.

  6. Narrative Finality

    Directory of Open Access Journals (Sweden)

    Armine Kotin Mortimer

    1981-01-01

    Full Text Available The cloturai device of narration as salvation represents the lack of finality in three novels. In De Beauvoir's Tous les hommes sont mortels an immortal character turns his story to account, but the novel makes a mockery of the historical sense by which men define themselves. In the closing pages of Butor's La Modification , the hero plans to write a book to save himself. Through the thrice-considered portrayal of the Paris-Rome relationship, the ending shows the reader how to bring about closure, but this collective critique written by readers will always be a future book. Simon's La Bataille de Pharsale , the most radical attempt to destroy finality, is an infinite text. No new text can be written. This extreme of perversion guarantees bliss (jouissance . If the ending of De Beauvoir's novel transfers the burden of non-final world onto a new victim, Butor's non-finality lies in the deferral to a future writing, while Simon's writer is stuck in a writing loop, in which writing has become its own end and hence can have no end. The deconstructive and tragic form of contemporary novels proclaims the loss of belief in a finality inherent in the written text, to the profit of writing itself.

    Probiotic formulations are widely used and are proposed to have a variety of beneficial effects, depending on the probiotic strains present in the product. The impact of drying processes on the viability of probiotics is well documented. However, the impact of these processes on probiotics functionality remains unclear. In this work, we investigated variations in seven different bacterial markers after various desiccation processes. Markers were composed of four different viability evaluation (combining two growth abilities and two cytometric measurements) and in three in vitro functionalities: stimulation of IL-10 and IL-12 production by PBMCs (immunomodulation) and bacterial adhesion to hexadecane. We measured the impact of three drying processes (air-drying, freeze-drying and spray-drying), without the use of protective agents, on three types of probiotic bacteria: Bifidobacterium bifidum, Lactobacillus plantarum and Lactobacillus zeae. Our results show that the bacteria respond differently to the three different drying processes, in terms of viability and functionality. Drying methods produce important variations in bacterial immunomodulation and hydrophobicity, which are correlated. We also show that adherence can be stimulated (air-drying) or inhibited (spray-drying) by drying processes. Results of a multivariate analysis show no direct correlation between bacterial survival and functionality, but do show a correlation between probiotic responses to desiccation-rewetting and the process used to dry the bacteria.

    Specialized, bimodal neural systems integrate visual and tactile information in the space near the hand. Here, we show that visuo-tactile representations allow attention to influence early perceptual processing, namely, figure-ground assignment. Regions that were reached toward were more likely than other regions to be assigned as foreground figures, and hand position competed with image-based information to bias figure-ground assignment. Our findings suggest that hand position allows attention to influence visual perceptual processing and that visual processes typically viewed as unimodal can be influenced by bimodal visuo-tactile representations.

  9. Glocal Multimedia Art as an Unbreakable Narrative

    Directory of Open Access Journals (Sweden)

    Vesna Srnic

    2018-04-01

    Full Text Available The usual theory of health and illness unfortunately with its dominant linguistic power incorporated by discursive constructivism, is based equally on the national imagination and issues of „broken narrative“, which causes a broader ignorance of other integrative narratives, especially performative situational multimedia art. There are no glocal multimedially orchestrated art narratives with ego-centrism and nationalism in their basis. Situational performativity of mixed glocal (global and local reality in multimedia art, seems to the superficial observer like  a mirror or „schizoid“ reality, but in actuality is the astonished multitasked „result“ of the primal, transpersonal, affective process of individuation and blossoming awareness, both of individuals and re-conceptualised society as a whole. Glocal Multimedia Art is our syntagma for a new holistic approach to experience. Thus we orchestrate our own as well as a wider existence from the heart of nature, via affective primordial and cosmic connection. Therefore, we can talk about the phenomenon of the authenticity of the World Sound/Image in a renewing creation of existence through glocal multimedia art and pure experience.  A new philosophy for new media by Mark B. N. Hansen is very important in this area of research as a post-visual affectivity of digital art expressed in a transitional body technique of “framing function” in digital mode. This work is a contribution to the process of anthropologisation of technology through the inclusion of artistic multimedia narratives in healthy, innovative education at institutions and operationally in the wider social re-evaluated reality.

  12. Temporal factors affecting somatosensory-auditory interactions in speech processing

    Directory of Open Access Journals (Sweden)

    Takayuki eIto

    2014-11-01

    Full Text Available Speech perception is known to rely on both auditory and visual information. However, sound specific somatosensory input has been shown also to influence speech perceptual processing (Ito et al., 2009. In the present study we addressed further the relationship between somatosensory information and speech perceptual processing by addressing the hypothesis that the temporal relationship between orofacial movement and sound processing contributes to somatosensory-auditory interaction in speech perception. We examined the changes in event-related potentials in response to multisensory synchronous (simultaneous and asynchronous (90 ms lag and lead somatosensory and auditory stimulation compared to individual unisensory auditory and somatosensory stimulation alone. We used a robotic device to apply facial skin somatosensory deformations that were similar in timing and duration to those experienced in speech production. Following synchronous multisensory stimulation the amplitude of the event-related potential was reliably different from the two unisensory potentials. More importantly, the magnitude of the event-related potential difference varied as a function of the relative timing of the somatosensory-auditory stimulation. Event-related activity change due to stimulus timing was seen between 160-220 ms following somatosensory onset, mostly around the parietal area. The results demonstrate a dynamic modulation of somatosensory-auditory convergence and suggest the contribution of somatosensory information for speech processing process is dependent on the specific temporal order of sensory inputs in speech production.

  13. Narrative self-appropriation: embodiment, alienness, and personal responsibility in the context of borderline personality disorder.

    Science.gov (United States)

    Køster, Allan

    2017-12-01

    It is often emphasised that persons diagnosed with borderline personality disorder (BPD) show difficulties in understanding their own psychological states. In this article, I argue that from a phenomenological perspective, BPD can be understood as an existential modality in which the embodied self is profoundly saturated by an alienness regarding the person's own affects and responses. However, the balance of familiarity and alienness is not static, but can be cultivated through, e.g., psychotherapy. Following this line of thought, I present the idea that narrativising experiences can play an important role in processes of appropriating such embodied self-alienness. Importantly, the notion of narrative used is that of a scalar conception of narrativity as a variable quality of experience that comes in degrees. From this perspective, narrative appropriation is a process of gradually attributing the quality of narrativity to experiences, thereby familiarising the moods, affects, and responses that otherwise govern 'from behind'. Finally, I propose that the idea of a narrative appropriation of embodied self-alienness is also relevant to the much-debated question of personal responsibility in BPD, particularly as this question plays out in psychotherapeutic contexts where a narrative self-appropriation may facilitate an increase in sense of autonomy and reduce emotions of guilt and shame.

    Chemical processes of biodiesel production are energy-consuming and generate undesirable by-products such as soaps and polymeric pigments that retard separation of pure methyl or ethyl esters of fatty acids from glycerol and di- and monoacylglycerols. Enzymatic, lipase-catalyzed biodiesel synthesis has no such drawbacks. Comprehension of the latter process and an appreciable progress in production of robust preparations of lipases may soon result in the replacement of chemical catalysts with enzymes in biodiesel synthesis. Engineering of enzymatic biodiesel synthesis processes requires optimization of such factors as: molar ratio of substrates (triacylglycerols: alcohol), temperature, type of organic solvent (if any) and water activity. All of them are correlated with properties of lipase preparation. This paper reports on the interplay between the crucial parameters of the lipase-catalyzed reactions carried out in non-aqueous systems and the yield of biodiesel synthesis. (author)

  15. The Influence of Parameters Affecting Boron Removal by Electrocoagulation Process

    KAUST Repository

    Zeboudji, B.

    2013-04-01

    Boron removal in seawater desalination presents a particular challenge. In seawater reverse osmosis (SWRO) systems boron removal at low concentration (<0.5 mg/L) is usually achieved by a second pass using brackish water RO membranes. However, this process requires chemical addition and important additional investment, operation and maintenance, and energy costs. Electrocoagulation (EC) process can be used to achieve such low boron concentration. In this work, the removal of boron from aqueous solution was carried out by EC process using aluminum and iron electrodes. Several operating parameters on the removal efficiency such as initial pH, current density, initial boron ion concentration, feed concentration, gap between electrodes, and electrode material, were investigated. In the case of bipolar electrocoagulation (BEC), an optimum removal efficiency of 96% corresponding to a final boron concentration of 0.4 mg/L was achieved at a current density of 6 mA/cm2 and pH = 8 using aluminum electrodes. The concentration of NaCl was 2,500 mg/L and the gap between the electrodes of 0.5 cm. Furthermore, a comparison between monopolar electrocoagulation (MEC) and BEC using both aluminum and iron electrodes was carried out. Results showed that the BEC process has reduced the current density applied to obtain high level of boron removal in a short reaction time compared to MEC process. The high performance of the EC showed that the process could be used to reduce boron concentration to acceptable levels at low-cost and more environmentally friendly. © 2013 Copyright Taylor and Francis Group, LLC.

  1. The radiotherapy affects the cognitive processes; La radiotherapie affecte la cognition

    2009-10-15

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

  2. Infiltration and runoff generation processes in fire-affected soils

    Science.gov (United States)

    Moody, John A.; Ebel, Brian A.

    2014-01-01

    Post-wildfire runoff was investigated by combining field measurements and modelling of infiltration into fire-affected soils to predict time-to-start of runoff and peak runoff rate at the plot scale (1 m2). Time series of soil-water content, rainfall and runoff were measured on a hillslope burned by the 2010 Fourmile Canyon Fire west of Boulder, Colorado during cyclonic and convective rainstorms in the spring and summer of 2011. Some of the field measurements and measured soil physical properties were used to calibrate a one-dimensional post-wildfire numerical model, which was then used as a ‘virtual instrument’ to provide estimates of the saturated hydraulic conductivity and high-resolution (1 mm) estimates of the soil-water profile and water fluxes within the unsaturated zone.Field and model estimates of the wetting-front depth indicated that post-wildfire infiltration was on average confined to shallow depths less than 30 mm. Model estimates of the effective saturated hydraulic conductivity, Ks, near the soil surface ranged from 0.1 to 5.2 mm h−1. Because of the relatively small values of Ks, the time-to-start of runoff (measured from the start of rainfall),  tp, was found to depend only on the initial soil-water saturation deficit (predicted by the model) and a measured characteristic of the rainfall profile (referred to as the average rainfall acceleration, equal to the initial rate of change in rainfall intensity). An analytical model was developed from the combined results and explained 92–97% of the variance of  tp, and the numerical infiltration model explained 74–91% of the variance of the peak runoff rates. These results are from one burned site, but they strongly suggest that  tp in fire-affected soils (which often have low values of Ks) is probably controlled more by the storm profile and the initial soil-water saturation deficit than by soil hydraulic properties.

  5. Acute physical exercise affected processing efficiency in an auditory attention task more than processing effectiveness.

    Dutke, Stephan; Jaitner, Thomas; Berse, Timo; Barenberg, Jonathan

    2014-02-01

    Research on effects of acute physical exercise on performance in a concurrent cognitive task has generated equivocal evidence. Processing efficiency theory predicts that concurrent physical exercise can increase resource requirements for sustaining cognitive performance even when the level of performance is unaffected. This hypothesis was tested in a dual-task experiment. Sixty young adults worked on a primary auditory attention task and a secondary interval production task while cycling on a bicycle ergometer. Physical load (cycling) and cognitive load of the primary task were manipulated. Neither physical nor cognitive load affected primary task performance, but both factors interacted on secondary task performance. Sustaining primary task performance under increased physical and/or cognitive load increased resource consumption as indicated by decreased secondary task performance. Results demonstrated that physical exercise effects on cognition might be underestimated when only single task performance is the focus.

  6. Habitat Complexity in Aquatic Microcosms Affects Processes Driven by Detritivores.

    Directory of Open Access Journals (Sweden)

    Lorea Flores

    Full Text Available Habitat complexity can influence predation rates (e.g. by providing refuge but other ecosystem processes and species interactions might also be modulated by the properties of habitat structure. Here, we focussed on how complexity of artificial habitat (plastic plants, in microcosms, influenced short-term processes driven by three aquatic detritivores. The effects of habitat complexity on leaf decomposition, production of fine organic matter and pH levels were explored by measuring complexity in three ways: 1. as the presence vs. absence of habitat structure; 2. as the amount of structure (3 or 4.5 g of plastic plants; and 3. as the spatial configuration of structures (measured as fractal dimension. The experiment also addressed potential interactions among the consumers by running all possible species combinations. In the experimental microcosms, habitat complexity influenced how species performed, especially when comparing structure present vs. structure absent. Treatments with structure showed higher fine particulate matter production and lower pH compared to treatments without structures and this was probably due to higher digestion and respiration when structures were present. When we explored the effects of the different complexity levels, we found that the amount of structure added explained more than the fractal dimension of the structures. We give a detailed overview of the experimental design, statistical models and R codes, because our statistical analysis can be applied to other study systems (and disciplines such as restoration ecology. We further make suggestions of how to optimise statistical power when artificially assembling, and analysing, 'habitat complexity' by not confounding complexity with the amount of structure added. In summary, this study highlights the importance of habitat complexity for energy flow and the maintenance of ecosystem processes in aquatic ecosystems.

  7. Suprasegmental information affects processing of talking faces at birth.

    Science.gov (United States)

    Guellai, Bahia; Mersad, Karima; Streri, Arlette

    2015-02-01

    From birth, newborns show a preference for faces talking a native language compared to silent faces. The present study addresses two questions that remained unanswered by previous research: (a) Does the familiarity with the language play a role in this process and (b) Are all the linguistic and paralinguistic cues necessary in this case? Experiment 1 extended newborns' preference for native speakers to non-native ones. Given that fetuses and newborns are sensitive to the prosodic characteristics of speech, Experiments 2 and 3 presented faces talking native and nonnative languages with the speech stream being low-pass filtered. Results showed that newborns preferred looking at a person who talked to them even when only the prosodic cues were provided for both languages. Nonetheless, a familiarity preference for the previously talking face is observed in the "normal speech" condition (i.e., Experiment 1) and a novelty preference in the "filtered speech" condition (Experiments 2 and 3). This asymmetry reveals that newborns process these two types of stimuli differently and that they may already be sensitive to a mismatch between the articulatory movements of the face and the corresponding speech sounds.

  8. Sensitivity analysis on parameters and processes affecting vapor intrusion risk

    KAUST Repository

    Picone, Sara

    2012-03-30

    A one-dimensional numerical model was developed and used to identify the key processes controlling vapor intrusion risks by means of a sensitivity analysis. The model simulates the fate of a dissolved volatile organic compound present below the ventilated crawl space of a house. In contrast to the vast majority of previous studies, this model accounts for vertical variation of soil water saturation and includes aerobic biodegradation. The attenuation factor (ratio between concentration in the crawl space and source concentration) and the characteristic time to approach maximum concentrations were calculated and compared for a variety of scenarios. These concepts allow an understanding of controlling mechanisms and aid in the identification of critical parameters to be collected for field situations. The relative distance of the source to the nearest gas-filled pores of the unsaturated zone is the most critical parameter because diffusive contaminant transport is significantly slower in water-filled pores than in gas-filled pores. Therefore, attenuation factors decrease and characteristic times increase with increasing relative distance of the contaminant dissolved source to the nearest gas diffusion front. Aerobic biodegradation may decrease the attenuation factor by up to three orders of magnitude. Moreover, the occurrence of water table oscillations is of importance. Dynamic processes leading to a retreating water table increase the attenuation factor by two orders of magnitude because of the enhanced gas phase diffusion. © 2012 SETAC.

  9. From neurons to epidemics: How trophic coherence affects spreading processes

    Klaise, Janis; Johnson, Samuel

    2016-06-01

    Trophic coherence, a measure of the extent to which the nodes of a directed network are organised in levels, has recently been shown to be closely related to many structural and dynamical aspects of complex systems, including graph eigenspectra, the prevalence or absence of feedback cycles, and linear stability. Furthermore, non-trivial trophic structures have been observed in networks of neurons, species, genes, metabolites, cellular signalling, concatenated words, P2P users, and world trade. Here, we consider two simple yet apparently quite different dynamical models—one a susceptible-infected-susceptible epidemic model adapted to include complex contagion and the other an Amari-Hopfield neural network—and show that in both cases the related spreading processes are modulated in similar ways by the trophic coherence of the underlying networks. To do this, we propose a network assembly model which can generate structures with tunable trophic coherence, limiting in either perfectly stratified networks or random graphs. We find that trophic coherence can exert a qualitative change in spreading behaviour, determining whether a pulse of activity will percolate through the entire network or remain confined to a subset of nodes, and whether such activity will quickly die out or endure indefinitely. These results could be important for our understanding of phenomena such as epidemics, rumours, shocks to ecosystems, neuronal avalanches, and many other spreading processes.

    Solid Waste Storage Area (SWSA) 5 is known to be a significant source of contaminants, especially tritium ( 3 H), to the White Oak Creek (WOC) watershed. For example, Solomon et al. (1991) estimated the total 3 H discharge in Melton Branch (most of which originates in SWSA 5) for the 1988 water year to be 1210 Ci. A critical issue for making decisions concerning remedial actions at SWSA 5 is knowing whether the annual contaminant discharge is increasing or decreasing. Because (1) the magnitude of the annual contaminant discharge is highly correlated to the amount of annual precipitation (Solomon et al., 1991) and (2) a significant lag may exist between the time of peak contaminant release from primary sources (i.e., waste trenches) and the time of peak discharge into streams, short-term stream monitoring by itself is not sufficient for predicting future contaminant discharges. In this study we use 3 H to examine the link between contaminant release from primary waste sources and contaminant discharge into streams. By understanding and quantifying subsurface transport processes, realistic predictions of future contaminant discharge, along with an evaluation of the effectiveness of remedial action alternatives, will be possible. The objectives of this study are (1) to characterize the subsurface movement of contaminants (primarily 3 H) with an emphasis on the effects of matrix diffusion; (2) to determine the relative strength of primary vs secondary sources; and (3) to establish a methodology capable of determining whether the 3 H discharge from SWSA 5 to streams is increasing or decreasing

    Increasing interest in drugs acting on prelamin A has derived from the finding of prelamin A involvement in severe laminopathies. Amelioration of the nuclear morphology by inhibitors of prelamin A farnesylation has been widely reported in progeroid laminopathies. We investigated the effects on chromatin organization of two drugs inhibiting prelamin A processing by an ultrastructural and biochemical approach. The farnesyltransferase inhibitor FTI-277 and the non-peptidomimetic drug N-acetyl-S-farnesyl-L-cysteine methylester (AFCMe) were administered to cultured control human fibroblasts for 6 or 18 h. FTI-277 interferes with protein farnesylation causing accumulation of non-farnesylated prelamin A, while AFCMe impairs the last cleavage of the lamin A precursor and is expected to accumulate farnesylated prelamin A. FTI-277 caused redistribution of heterochromatin domains at the nuclear interior, while AFCMe caused loss of heterochromatin domains, increase of nuclear size and nuclear lamina thickening. At the biochemical level, heterochromatin-associated proteins and LAP2α were clustered at the nuclear interior following FTI-277 treatment, while they were unevenly distributed or absent in AFCMe-treated nuclei. The reported effects show that chromatin is an immediate target of FTI-277 and AFCMe and that dramatic remodeling of chromatin domains occurs following treatment with the drugs. These effects appear to depend, at least in part, on the accumulation of prelamin A forms, since impairment of prelamin A accumulation, here obtained by 5-azadeoxycytidine treatment, abolishes the chromatin effects. These results may be used to evaluate downstream effects of FTIs or other prelamin A inhibitors potentially useful for the therapy of laminopathies

  17. Understanding personal narratives: an approach to practice.

    2005-02-01

    This paper explores the need for and nature of personal narratives and their relevance to nursing practice. It proposes that the co-creative aesthetic process can be used to understand and co-create personal narratives through an emphasis on self-defining memories and metaphor. Many authors in nursing and other human sciences have recognized the need for and importance of personal narrative, its relationship to aesthetic knowing and its value in qualitative research and in practice. The role of memory and metaphor in the creation of meaning in personal narratives, however, has not been sufficiently explored in nursing literature. The nature of personal narrative is explored, focusing on the way meaning is created from self-defining memories using metaphor. Then, the importance of personal narratives in nursing practice is considered, followed by discussion about how meaning in personal narratives may be co-created between clients and nurses using an aesthetic process developed by the author. The co-creative aesthetic process is an example of nursing as art and can be used to co-create personal narratives in practice. The experience of co-creating a self story with a nurse can be healing, as the self story is heard by a caring person, memories are understood in new ways, and the self story is both confirmed and recreated.

  18. The relationship between mother narrative style and child memory.

    The question of whether children and infants have memory capabilities similar to adults has long been of interest. Until recently, it was thought that compared to adults, infants have very limited memory processing abilities. Knowledge about factors affecting a child's memory abilities can help families (specifically mothers) behave in a manner that best benefits their children in language and memory skills. The present study examines one factor that may underlie a child's memory capabilities; namely the mother's narrative style. Convenience sampling was used to select participants. Forty healthy children (mean age of 31.55 months, range 25-37 months) and their mothers were entered into the study. All participants were native Turkish speakers, from similar socioeconomic status backgrounds. Memory was assessed by a modified version of the Magic Shrinking Machine. Narrative style was assessed by the mother "reading" a Frog Story; a picture book with no words in it. Children were then grouped according to their mother's level of narrative style. Children's language skills were measured via the Turkish form of the CDI (Communicative Development Inventory) which was translated to Turkish as TIGE. To explore the relationships between mothers' narrative styles and children's memory and language skills and between children's language skills and memory capabilities, linear regressions were run. There were no significant correlations among any comparisons (P > 0.05). Children's language skills do not improve according to their mothers' narrative styles, and children do not show better memory abilities when mothers use more words and longer sentences. In order to have a better understanding of these relationships, future research that includes several more variables is needed. Child; Mother; Memory; Narrative style.

    Full Text Available The goal of this article is to introduce activity systems as a methodological tool in narrative inquiry to gain a holistic understanding of socially shared experiences from an examination of documents. The research question was how can qualitative researchers use activity systems as a tool for engaging in narrative inquiry of socially shared experiences to uncover new meanings by constructing a story? In this article, we share a sample analysis of our experience relying on documents and media as a form of narrative to begin to understand the socially shared human activity associated with net neutrality and its potential impact on U.S. residents. We end this article with reflections of lessons learned from our activity systems guided story construction process.

    Full Text Available With its capacity to unharness the power of narrative to promote meaning-making of lived experience, narrative inquiry is developing as a credible approach to research in several areas in the field of language teaching (Johnson, 2006. This article tells the story of two narrative researchers working in language teacher education who engaged in a collaborative narrative inquiry as both participants and inquirers, in order to learn more about narrative inquiry. The ‘bounded’ nature of their inquiry design provided a feasible way for them to explore their focus of research (i.e. their learning about narrative inquiry, and led them, through an iterative and reflexive process of analysing their narrative data, to formulate what they believe are essential ingredients of principled narrative inquiry work. Four narrative inquiry variables became the scaffolding which enabled them to answer their research questions, and are offered here as a heuristic for teaching practitioners, whether they be teachers, teacher educators or researchers, to guide them in narrative inquiries into their own work.

    Schaal, Susanne; Hecker, Tobias; Elbert, Thomas

    2015-01-01

    Background Depending on the exposure to traumatic stressors and combat, 20% to 50% of ex‐combatants present with trauma‐related disorders, and more than half of the members of armed groups have a proclivity to violence. Therefore, psychotherapeutic assistance should address both, trauma‐related suffering and the lowered threshold for aggressive behaviour. Objective Supporting the demobilization process of ex‐combatants in the eastern DR‐Congo, we implemented a version of Narrative Exposure Therapy adapted for Forensic Offender Rehabilitation (FORNET). Method In two successive dissemination stages (DS), local counsellors conducted FORNET. In DS1, they were trained by clinical experts, and in DS2, the by then experienced counsellors trained and supervised a second group of local counsellors (DS2). The training consisted of a 3‐week workshop covering theoretical concepts and practical therapeutic skills. In DS1 and DS2, a total of 98 demobilizing combatants received an intervention; treatment‐as‐usual served as the control condition. Posttraumatic stress disorder, appetitive aggression, depression severity and drug dependence were assessed prior to the intervention and 6 and 12 months later; additionally, we assessed reintegration success. Results Six months post‐intervention, FORNET significantly reduced Posttraumatic stress disorder symptoms but had less effect on the trait of appetitive aggression; moreover, beneficial effects were found for depression severity and drug dependence as well as for reintegration indices. Treatment gains were retained at 12 months. Conclusions Individuals without previous training in psychotherapy can learn to effectively apply the brief intervention FORNET and support the demobilization process in ongoing conflicts. The study suggests that it is possible to pass down psychotherapeutic techniques over generations of counsellors. © 2015 The Authors. Clinical Psychology & Psychotherapy published by John Wiley

    The quality of ICT tomograms is affected by detecting processing parameters and image processing methods besides the performances of ICT systems. Optimal processing parameters and image processing methods can promote not only the quality of tomogram but also the resolution. Some research work was carried out about processing parameters and image processing methods including choice of collimator, filter, false color composite image. And some examples were given in this paper, which can provide the ICT analyst with reference. (authors)

    Temporal information in clinical narratives plays an important role in patients' diagnosis, treatment and prognosis. In order to represent narrative information accurately, medical natural language processing (MLP) systems need to correctly identify and interpret temporal information. To promote research in this area, the Informatics for Integrating Biology and the Bedside (i2b2) project developed a temporally annotated corpus of clinical narratives. This corpus contains 310 de-identified discharge summaries, with annotations of clinical events, temporal expressions and temporal relations. This paper describes the process followed for the development of this corpus and discusses annotation guideline development, annotation methodology, and corpus quality. Copyright © 2013 Elsevier Inc.

    Full Text Available This paper reports on the effects of using wiki-based process writing in Singapore’s Chinese as a Second Language (CSL scenarios. A group of 32 Secondary 1 (Seventh Grade students (“Students” received various forms of online scaffolding at different steps of the writing process over two years. A whole set of teaching materials on 45 writing skills was developed and uploaded to the Wiki platform through five recursive cycles. In each cycle, the students were encouraged to apply skills they learned via Wiki platform in their writing and afterwards work as a team in the platform to peer-review each other’s first draft. With feedback received from peer revision, students proceeded to edit their first draft, focusing on the content of narratives and the appropriateness on their use of micro writing skills. The scaffolding decreased as the project progressed. Students’ pre-, mid- and post-writing tests were marked and compared. The authors analyzed the impact that the feedback in the process had towards the students’ overall writing performance. It was discovered that students' quality of written products was improved in general. It was also discovered that students benefited the most from giving remarks to their peers’ writing. The revision patterns of high, medium and low language ability students were also compared. It was found that the higher the language ability of the students, the more concerned they were with macro level for their revisions. ICT-mediated process writing has not garnered much attention in the field of CSL. The study hopes to contribute to the literature of ICTmediated writing instruction in the field of CSL.

  8. Facial affect processing and depression susceptibility: cognitive biases and cognitive neuroscience.

    Facial affect processing is essential to social development and functioning and is particularly relevant to models of depression. Although cognitive and interpersonal theories have long described different pathways to depression, cognitive-interpersonal and evolutionary social risk models of depression focus on the interrelation of interpersonal experience, cognition, and social behavior. We therefore review the burgeoning depressive facial affect processing literature and examine its potential for integrating disciplines, theories, and research. In particular, we evaluate studies in which information processing or cognitive neuroscience paradigms were used to assess facial affect processing in depressed and depression-susceptible populations. Most studies have assessed and supported cognitive models. This research suggests that depressed and depression-vulnerable groups show abnormal facial affect interpretation, attention, and memory, although findings vary based on depression severity, comorbid anxiety, or length of time faces are viewed. Facial affect processing biases appear to correspond with distinct neural activity patterns and increased depressive emotion and thought. Biases typically emerge in depressed moods but are occasionally found in the absence of such moods. Indirect evidence suggests that childhood neglect might cultivate abnormal facial affect processing, which can impede social functioning in ways consistent with cognitive-interpersonal and interpersonal models. However, reviewed studies provide mixed support for the social risk model prediction that depressive states prompt cognitive hypervigilance to social threat information. We recommend prospective interdisciplinary research examining whether facial affect processing abnormalities promote-or are promoted by-depressogenic attachment experiences, negative thinking, and social dysfunction.

    2017-01-01

    There is an increasing need for a worldwide professional integration of conventional medicine and traditional/complementary whole medical systems (WMSs). However, the integration is perceived by conventional medicine as problematic or unacceptable, because of a supposed lack of evidence for specific effects of WMSs therapies and supposed prescientific or unscientific paradigms of WMSs. To review the literature on the features of WMSs, similarities and differences between conventional medicine and WMSs, and scientific and clinical practice issues that should be dealt with in order to promote the integration process. A critical, narrative review of the literature on six WMSs. Key factors for the integration of WMSs and conventional medicine are as follows: legal frameworks, quality standards, high-quality research on safety and efficacy of WMS interventions, infrastructure, and financial resources. For scientific assessment of WMSs, there are unresolved ontological, epistemological, and methodological issues and issues of diagnostics, therapy delivery, and outcome assessment in clinical practice. Future research not only should be directed at quality assurance and generating the necessary data on safety and efficacy/effectiveness but also should address more fundamental (ontological, epistemological, and methodological) issues, in order to overcome the differences between WMSs and conventional medicine.

    Reading is not only “cold” information processing, but involves affective and aesthetic processes that go far beyond what current models of word recognition, sentence processing, or text comprehension can explain. To investigate such “hot” reading processes, standardized instruments that quantify both psycholinguistic and emotional variables at the sublexical, lexical, inter-, and supralexical levels (e.g., phonological iconicity, word valence, arousal-span, or passage suspense) are necessary. One such instrument, the Berlin Affective Word List (BAWL) has been used in over 50 published studies demonstrating effects of lexical emotional variables on all relevant processing levels (experiential, behavioral, neuronal). In this paper, we first present new data from several BAWL studies. Together, these studies examine various views on affective effects in reading arising from dimensional (e.g., valence) and discrete emotion features (e.g., happiness), or embodied cognition features like smelling. Second, we extend our investigation of the complex issue of affective word processing to words characterized by a mixture of affects. These words entail positive and negative valence, and/or features making them beautiful or ugly. Finally, we discuss tentative neurocognitive models of affective word processing in the light of the present results, raising new issues for future studies. PMID:26089808

    This study attempted to replicate negative bias and depressive explanatory style in depression using life narratives. The two central aspects of narrative, temporal succession and evaluation, were also explored. These aspects were tested for the first time using entire life narratives of 17 depressed inpatients and non-depressed controls matched for sex and educational level. Negative bias and depressive explanatory style were replicated as typical for the depressed group. Life narratives of depressed patients also deviated more from a linear temporal order and compared less frequently the past with the present. Contrary to expectations, the depressed did not differ in the overall frequency of evaluations. However, they used more past than present evaluations and more experience-near evaluations than cognitive evaluations, suggesting that they are more immersed in past experiences. It is concluded that negative bias and depressive explanatory style can be found also in a naturalistic narrative measure, and that depression affects the two major aspects of narrative. It is argued that life narratives, as measures close to everyday clinical practice and as the most encompassing form of self-representation, should complement more experimental procedures in the study of cognitive and communicative processes in psychopathology. 2007 Wiley-Liss, Inc.

    Narratives are an integral part of human expression. In the graphic form, they range from cave paintings to Egyptian hieroglyphics, from the Bayeux Tapestry to modern day comic books (Kunzle, 1973; McCloud, 1993). Yet not much research has addressed the structure and comprehension of narrative images, for example, how do people create meaning out of sequential images? This piece helps fill the gap by presenting a theory of Narrative Grammar. We describe the basic narrative categories and their relationship to a canonical narrative arc, followed by a discussion of complex structures that extend beyond the canonical schema. This demands that the canonical arc be reconsidered as a generative schema whereby any narrative category can be expanded into a node in a tree structure. Narrative "pacing" is interpreted as a reflection of various patterns of this embedding: conjunction, left-branching trees, center-embedded constituencies, and others. Following this, diagnostic methods are proposed for testing narrative categories and constituency. Finally, we outline the applicability of this theory beyond sequential images, such as to film and verbal discourse, and compare this theory with previous approaches to narrative and discourse.

To provide an alternative to the repository image of memory in organization, organizational remembering is conceptualized as narrative, where narrative represents a way to organize the selection and interpretation of the past....... The narrative perspective deals with both the experiential and contextual nature of remembering by addressing concerns raised by critiques of organizational memory studies, namely, the subjective experience of remembering and the social and historical context in which remembering takes place. Antenarrative...... the narrative perspective reveals ruptures and ambiguities that characterize organizational remembering that would remain hidden in the organizational memory studies approach....

    To report on the development of a framework of narrative practice, in residential care settings for older people. Residential care settings for older people provide care for people who are no longer able to live in their own home. To date, the impact and structure of nursing practice on care provision in these settings has proved difficult to conceptualise within a specific nursing theory framework. A hermeneutic approach incorporating narrative methods was used. Forty-six narrative interviews with older people in residential care were secondary-analysed for key themes through a three-stage process: by the first author, four focus groups of 12 clinical nurse managers and two independent experts. Themes were also derived from a focus group of eight residents who explored person-centredness and narrative. Finally, the combined findings were used to derive a single set of themes. The secondary data analysis process led to the development of a framework of narrative practice for the care of older people in residential settings. The framework is influenced by narrative enquiry, person-centred practice and practice development. It has four pillars, prerequisites, care processes, care environment and narrative aspects of care. To operationalise the framework of narrative practice, three narrative elements, narrative knowing, narrative being and narrative doing, need to be considered. Working with the foundational pillars and the narrative elements would enable staff to 'work in a storied way' and provide person-centred outcomes and a narrative informed philosophy of care for older adults in residential care. This framework provides nurses with a template that confirms the identity of the older person taking account of their biography. The framework outlines an approach that provides staff with a template on how to provide person-centred care in a narrative way. © 2013 John Wiley & Sons Ltd.

  16. Macroscopic brain dynamics during verbal and pictorial processing of affective stimuli.

    2006-01-01

    Emotions can be viewed as action dispositions, preparing an individual to act efficiently and successfully in situations of behavioral relevance. To initiate optimized behavior, it is essential to accurately process the perceptual elements indicative of emotional relevance. The present chapter discusses effects of affective content on neural and behavioral parameters of perception, across different information channels. Electrocortical data are presented from studies examining affective perception with pictures and words in different task contexts. As a main result, these data suggest that sensory facilitation has an important role in affective processing. Affective pictures appear to facilitate perception as a function of emotional arousal at multiple levels of visual analysis. If the discrimination between affectively arousing vs. nonarousing content relies on fine-grained differences, amplification of the cortical representation may occur as early as 60-90 ms after stimulus onset. Affectively arousing information as conveyed via visual verbal channels was not subject to such very early enhancement. However, electrocortical indices of lexical access and/or activation of semantic networks showed that affectively arousing content may enhance the formation of semantic representations during word encoding. It can be concluded that affective arousal is associated with activation of widespread networks, which act to optimize sensory processing. On the basis of prioritized sensory analysis for affectively relevant stimuli, subsequent steps such as working memory, motor preparation, and action may be adjusted to meet the adaptive requirements of the situation perceived.

    Theory of Mind (ToM) is the ability to attribute thoughts, intentions and beliefs to others. This involves component processes, including cognitive perspective taking (cognitive ToM) and understanding emotions (affective ToM). This study assessed the distinction and overlap of neural processes involved in these respective components, and also investigated their development between adolescence and adulthood. While data suggest that ToM develops between adolescence and adulthood, these populations have not been compared on cognitive and affective ToM domains. Using fMRI with 15 adolescent (aged 11-16 years) and 15 adult (aged 24-40 years) males, we assessed neural responses during cartoon vignettes requiring cognitive ToM, affective ToM or physical causality comprehension (control). An additional aim was to explore relationships between fMRI data and self-reported empathy. Both cognitive and affective ToM conditions were associated with neural responses in the classic ToM network across both groups, although only affective ToM recruited medial/ventromedial PFC (mPFC/vmPFC). Adolescents additionally activated vmPFC more than did adults during affective ToM. The specificity of the mPFC/vmPFC response during affective ToM supports evidence from lesion studies suggesting that vmPFC may integrate affective information during ToM. Furthermore, the differential neural response in vmPFC between adult and adolescent groups indicates developmental changes in affective ToM processing.

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

    Full Text Available The assessment of possible genetic relationships between pairs of proposed narrative parallels currently relies on subjective conventional wisdom-based criteria. This essay presents an attempt at categorizing patterns of narrative evolution through the comparison of variants of orally-composed, fixed-text Sanskrit tales. Systematic examination of the changes that took place over the developmental arc of _The Tale of Cyavana_ offers a number of insights that may be applied to the understanding of the evolution of oral narratives in general. An evidence-based exposition of the principles that govern the process of narrative evolution could provide more accurate diagnostic tools for evaluating narrative parallels.

  20. Emotions, narratives, and ethical mindfulness.

    Clinical care is laden with emotions, from the perspectives of both clinicians and patients. It is important that emotions are addressed in health professions curricula to ensure that clinicians are humane healers as well as technical experts. Emotions have a valuable and generative role in health professional ethics education.The authors have previously described a narrative ethics pedagogy, the aim of which is to develop ethical mindfulness. Ethical mindfulness is a state of being that acknowledges everyday ethics and ethically important moments as significant in clinical care, with the aim of enabling ethical clinical practice. Using a sample narrative, the authors extend this concept to examine five features of ethical mindfulness as they relate to emotions: (1) being sensitized to emotions in everyday practice, (2) acknowledging and understanding the ways in which emotions are significant in practice, (3) being able to articulate the emotions at play during ethically important moments, (4) being reflexive and acknowledging both the generative aspects and the limitations of emotions, and (5) being courageous.The process of writing and engaging with narratives can lead to ethical mindfulness, including the capacity to understand and work with emotions. Strategies for productively incorporating emotions in narrative ethics teaching are described. This can be a challenging domain within medical education for both educators and health care students and thus needs to be addressed sensitively and responsibly. The potential benefit of educating health professionals in a way which addresses emotionality in an ethical framework makes the challenges worthwhile.

    Family caregivers' views and experiences related to treatment usage processes by their adult relatives with serious and persistent mental illness (SPMI) were empirically examined in a sample of Latino caregivers (n = 17) who were users of services at the National Alliance on Mental Illness (NAMI) in a predominantly Latino- (80%) and Mexican-descent large city in the Southwest United States. We conducted a stability check of qualitative findings with a second sample of Latino caregivers with no exposure to NAMI (n = 15). Overall, the combined sample (N = 32) compared similarly with larger samples of Latino adults and caregivers in quantitative measures of acculturation, familism, caregiver stigma, and depression symptoms. Together, caregivers' stigma and cultural beliefs, such as vergüenza (shame), use of folk healers, and lack of insurance, were major reported barriers to service usage. Family support (and lack of) for treatment also weighed heavily as a facilitator (and a barrier) of service usage, thus highlighting the complexity of family relationship contexts. Substantial portions of caregivers reported that treatment initiation was prompted by psychiatric hospitalization (50%), and that positive experiences with service providers were influential in treatment retention (72%). Given the high levels of family involvement reported among Latino caregivers, the findings underscore the potential role of family caregivers in treatment engagement and retention. Future research is needed that examines family caregivers' role in treatment with models that consider the interplay between cultural background, family level relationships, and service system contexts.

  2. Narratives of change and reform processes: global and local transactions in French psychiatric hospital reform after the Second World War.

    Henckes, Nicolas

    2009-02-01

    As with the rest of biomedicine, psychiatry has, since the Second World War, developed under the strong influence of the transnational accumulation of a whole series of practices and knowledge. Anthropology has taught us to pay attention to the transactions between local-level actors and those operating at the global level in the construction of this new world of medicine. This article examines the role played by the recommendations of the WHO Expert Committee of Mental Health in the reform of the French mental health system during the 1950s. Rooted in the experience of practitioners and administrators participating in the process of reforming local psychiatric systems, the recommendations of the WHO Expert Committee developed a new vision of regulating psychiatry, based on professionalism and an idea of a normativity of the doctor-patient relation. This article shows how, by mobilizing the WHO reports' recommendations, French administrators and doctors succeeded in creating a typically French object: "the psychiatric sector", founded on elaborating a new mandate for the psychiatric profession. The article thus questions the deinstitutionalization model as an explanation of transformations of the structure of the French psychiatry system in the post-war period.

    Full Text Available The paper presents research conducted within the narrative psychology paradigm. Its main purpose was to explore the relationships between features of adolescents’ identity narratives and their assessments of family functioning and themselves as family members. The choice of subject was motivated by current reports on identity formation difficulties in adolescence. Adolescents’ narratives were subjected to quantitative and qualitative analysis. Associations between specific aspects of self-narratives and participants’ perceptions of how their families functioned and how they functioned in the family system were evaluated. The results confirm the hypothesized relationships between the features of adolescents’ narratives and evaluations of their families and self-assessments of their own functioning in those families. Multi-thematic, content-rich and positively evaluated self-narratives are associated with positive assessments of selected aspects of family functioning and adolescents’ own functioning within the family. The following aspects of family assessment are significant: affective expression, level of emotional involvement in the family, level of control, family role performance and communication. Important factors in the self-assessment were: sense of competence in family role performance, assessment of one’s communication, behavior control and affective expression.

    Attachment is critical to each individual. It affects the cognitive-affective processing of social information. The present study examines how attachment affects the processing of social information, specifically maternal information. We assessed the behavioral and electrophysiological responses to maternal information (compared to non-specific others) in a Go/No-go Association Task (GNAT) with 22 participants. The results illustrated that attachment affected maternal information processing during three sequential stages of information processing. First, attachment affected visual perception, reflected by enhanced P100 and N170 elicited by maternal information as compared to others information. Second, compared to others, mother obtained more attentional resources, reflected by faster behavioral response to maternal information and larger P200 and P300. Finally, mother was evaluated positively, reflected by shorter P300 latency in a mother + good condition as compared to a mother + bad condition. These findings indicated that the processing of attachment-relevant information is neurologically differentiated from other types of social information from an early stage of perceptual processing to late high-level processing.

    Deficit in facial affect recognition is a well-documented impairment in schizophrenia, closely connected to social outcome. This deficit could be related to psychopathology, but also to a broader dysfunction in processing facial information. In addition, patients with schizophrenia inadequately use configural information-a type of processing that relies on spatial relationships between facial features. To date, no study has specifically examined the link between symptoms and misuse of configural information in the deficit in facial affect recognition. Unmedicated schizophrenia patients (n = 30) and matched healthy controls (n = 30) performed a facial affect recognition task and a face inversion task, which tests aptitude to rely on configural information. In patients, regressions were carried out between facial affect recognition, symptom dimensions and inversion effect. Patients, compared with controls, showed a deficit in facial affect recognition and a lower inversion effect. Negative symptoms and lower inversion effect could account for 41.2% of the variance in facial affect recognition. This study confirms the presence of a deficit in facial affect recognition, and also of dysfunctional manipulation in configural information in antipsychotic-free patients. Negative symptoms and poor processing of configural information explained a substantial part of the deficient recognition of facial affect. We speculate that this deficit may be caused by several factors, among which independently stand psychopathology and failure in correctly manipulating configural information.

    Full Text Available Jackie K Gollan, Laina Rosebrock, Denada Hoxha, Katherine L Wisner Asher Center for the Study and Treatment of Depressive Disorders, Department of Psychiatry and Behavioral Sciences, Northwestern University Feinberg School of Medicine, Chicago, IL, USA Abstract: The aim of this review is to provide an overview of the research in attentional processing and affective reactivity in pregnancy and postpartum to inform future research. Numerous changes occur in attentional processing and affective reactivity across the childbearing period. This review focuses on the definition and methods of measuring attentional processing and affective reactivity. We discuss research studies that have examined the changes in these two processes during the perinatal phases of pregnancy and postpartum, with and without depression and anxiety. We evaluate the importance of using multiple levels of measurement, including physiological and neuroimaging techniques, to study these processes via implicit and explicit tasks. Research that has identified regions of brain activation using functional magnetic resonance imaging as well as other physiological assessments is integrated into the discussion. The importance of using sophisticated methodological techniques in future studies, such as multiple mediation models, for the purpose of elucidating mechanisms of change during these processes in pregnancy and postpartum is emphasized. We conclude with a discussion of the effect of these processes on maternal psychological functioning and infant outcomes. These processes support a strategy for individualizing treatment for pregnant and postpartum women suffering from depression and anxiety.

    Full Text Available The manner in which individuals recall an autobiographical positive life event has affective consequences. Two studies addressed the processing styles during positive memory recall in a non-clinical sample. Participants retrieved a positive memory which was self-generated (Study 1, n = 70 or experimenter-chosen (i.e., academic achievement, Study 2, n = 159, followed by the induction of one of three processing styles (between-subjects: In Study 1, a ‘concrete/imagery’ vs. ‘abstract/verbal’ processing style was compared. In Study 2, a ‘concrete/imagery’, ‘abstract/verbal’, and ‘comparative/verbal’ processing style were compared. The processing of a personal memory in a concrete/imagery-based way led to a larger increase in positive affect compared to abstract/verbal processing in Study 1, as well as compared to comparative/verbal thinking in Study 2. Results of Study 2 further suggest that it is making unfavourable verbal comparisons that may hinder affective benefits to positive memories (rather then general abstract/verbal processing per se. The comparative/verbal thinking style failed to lead to improvements in positive affect, and with increasing levels of depressive symptoms it had a more negative impact on change in positive affect. We found no evidence that participant’s tendency to have dampening thoughts in response to positive affect in daily life contributed to the affective impact of positive memory recall. The results support the potential for current trainings in boosting positive memories and mental imagery, and underline the search for parameters that determine at times deleterious outcomes of abstract/verbal memory processing in the face of positive information.

    Late-life depression (LLD) in the elderly was reported to present with emotion dysregulation accompanied by high perceived loneliness. Previous research has suggested that LLD is a disorder of connectivity and is associated with aberrant network properties. On the other hand, perceived loneliness is found to adversely affect the brain, but little is known about its neurobiological basis in LLD. The current study investigated the relationships between the structural connectivity, functional connectivity during affective processing, and perceived loneliness in LLD. The current study included 54 participants aged >60 years of whom 31 were diagnosed with LLD. Diffusion tensor imaging (DTI) data and task-based functional magnetic resonance imaging (fMRI) data of an affective processing task were collected. Network-based statistics and graph theory techniques were applied, and the participants' perceived loneliness and depression level were measured. The affective processing task included viewing affective stimuli. Structurally, a loneliness-related sub-network was identified across all subjects. Functionally, perceived loneliness was related to connectivity differently in LLD than that in controls when they were processing negative stimuli, with aberrant networking in subcortical area. Perceived loneliness was identified to have a unique role in relation to the negative affective processing in LLD at the functional brain connectional and network levels. The findings increas our understanding of LLD and provide initial evidence of the neurobiological mechanisms of loneliness in LLD. Loneliness might be a potential intervention target in depressive patients.

    Alcohol dependence (AD) has global effects on brain structure and function, including frontolimbic regions regulating affective processing. Preliminary evidence suggests alcohol blunts limbic response to negative affective stimuli and increases activation to positive affective stimuli. Subtle gender differences are also evident during affective processing. Fourteen abstinent AD individuals (8 F, 6 M) and 14 healthy controls (9 F, 5 M), ages 23 to 60, were included in this facial affective processing functional magnetic resonance imaging pilot study. Whole-brain linear regression analyses were performed, and follow-up analyses examined whether AD status significantly predicted depressive symptoms and/or coping. Fearful Condition-The AD group demonstrated reduced activation in the right medial frontal gyrus, compared with controls. Gender moderated the effects of AD in bilateral inferior frontal gyri. Happy Condition-AD individuals had increased activation in the right thalamus. Gender moderated the effects of AD in the left caudate, right middle frontal gyrus, left paracentral lobule, and right lingual gyrus. Interactive AD and gender effects for fearful and happy faces were such that AD men activated more than control men, but AD women activated less than control women. Enhanced coping was associated with greater activation in right medial frontal gyrus during fearful condition in AD individuals. Abnormal affective processing in AD may be a marker of alcoholism risk or a consequence of chronic alcoholism. Subtle gender differences were observed, and gender moderated the effects of AD on neural substrates of affective processing. AD individuals with enhanced coping had brain activation patterns more similar to controls. Results help elucidate the effects of alcohol, gender, and their interaction on affective processing.

    Full Text Available The in vivo neural activity of the pons during the perception of affective stimuli has not been studied despite the strong implications of its role in affective processing. To examine the activity of the pons during the viewing of affective stimuli, and to verify its functional and structural connectivity with other affective neural correlates, a multimodal magnetic resonance imaging methodology was employed in this study. We observed the in vivo activity of the pons when viewing affective stimuli. Furthermore, small-world connectivity indicated that the functional connectivity (FC between the pons and the cortico-limbic affective regions was meaningful, with the coefficient λ being positively associated with self-reported emotional reactivity. The FC between the pons and the cortico-limbic-striatal areas was related to self-reported negative affect. Corroborating this finding was the observation that the tract passing through the pons and the left hippocampus was negatively related to self-reported positive affect and positively correlated with emotional reactivity. Our findings support the framework that the pons works conjunctively with the distributed cortico-limbic-striatal systems in shaping individuals' affective states and reactivity. Our work paves the path for future research on the contribution of the pons to the precipitation and maintenance of affective disorders.

    2013-03-01

    A growing body of research suggests that smoking portrayals in movies influence adolescent tobacco use. However, the mechanism for this influence remains unclear. The aim of this paper is to provide an overview of research on narrative transportation theory, particularly as applied to movies and smoking. We propose that this theory can provide a valuable framework for guiding research on the role of entertainment media in smoking and other addictive behaviors. We review empirical work on transportation theory and highlight the psychological mechanisms underlying transportation effects. 'Transportation into narrative worlds' refers to cognitive, emotional and imagery engagement into a narrative (including movies and entertainment media). We link this work with research on the effects of movie smoking. Research suggests that individuals who are more highly transported into narratives show greater attitude, belief and behavior change. Transportation effects work through reducing counterarguing, creating connections (identification and liking) with characters and increasing perceptions of realism and emotional involvement. We propose several future directions and research challenges for applying a transportation framework to the issue of entertainment media effects on smoking and tobacco disparities. Understanding factors contributing to transportation may provide a more nuanced view of who will be affected by movie smoking, and understanding the psychological processes underlying narrative persuasion may guide intervention efforts. Narrative transportation theory suggests that individuals' cognitive, emotional and imagery immersion in a narrative is a key mechanism of attitude, belief and behavior change. This theory provides a potentially generative and psychologically grounded framework for increasing knowledge about the boundary conditions and processes underlying the effects of entertainment media on tobacco use. © 2012 The Authors, Addiction © 2012 Society for

    2014-01-01

    Embodied cognition contends that the representation and processing of concepts involve perceptual, somatosensory, motoric, and other physical re-experiencing information. In this view, affective concepts are also grounded in physical information. For instance, people often say "feeling down" or "cheer up" in daily life. These phrases use spatial information to understand affective concepts. This process is referred to as valence-space metaphor. Valence-space metaphors refer to the employment of spatial information (lower/higher space) to elaborate affective concepts (negative/positive concepts). Previous studies have demonstrated that processing affective words affects performance on a spatial detection task. However, the mechanism(s) behind this effect remain unclear. In the current study, we hypothesized that processing affective words might produce spatial information. Consequently, spatial information would affect the following spatial cue detection/discrimination task. In Experiment 1, participants were asked to remember an affective word. Then, they completed a spatial cue detection task while event-related potentials were recorded. The results indicated that the top cues induced enhanced amplitude of P200 component while participants kept positive words relative to negative words in mind. On the contrary, the bottom cues induced enhanced P200 amplitudes while participants kept negative words relative to positive words in mind. In Experiment 2, we conducted a behavioral experiment that employed a similar paradigm to Experiment 1, but used arrows instead of dots to test the attentional nature of the valence-space metaphor. We found a similar facilitation effect as found in Experiment 1. Positive words facilitated the discrimination of upper arrows, whereas negative words facilitated the discrimination of lower arrows. In summary, affective words might activate spatial information and cause participants to allocate their attention to corresponding locations

    The processes that affect significantly the transport of contaminants through the near field and far field of a deep geological repository of spent nuclear fuel were studied. The processes can be generally divided into (i) processes related to the release of radionuclides from the spent nuclear fuel; (ii) processes related to the radionuclide transport mechanisms (such as advection and diffusion); and (iii) processes affecting the rate of radionuclide migration through the multi-barrier repository system. A near-field and geosphere model of an unspecified geological repository sited in a crystalline rock is also described. Focus of the treatment is on the effects of the different processes on the activity flow of the major safety-relevant radionuclides. The activity flow was simulated for one spent fuel cask by using the GoldSim simulation tool. (orig.)

  5. On whether mirror neurons play a significant role in processing affective prosody.

    Ramachandra, Vijayachandra

    2009-02-01

    Several behavioral and neuroimaging studies have indicated that both right and left cortical structures and a few subcortical ones are involved in processing affective prosody. Recent investigations have shown that the mirror neuron system plays a crucial role in several higher-level functions such as empathy, theory of mind, language, etc., but no studies so far link the mirror neuron system with affective prosody. In this paper is a speculation that the mirror neuron system, which serves as a common neural substrate for different higher-level functions, may play a significant role in processing affective prosody via its connections with the limbic lobe. Actual research must apply electrophysiological and neuroimaging techniques to assess whether the mirror neuron systems underly affective prosody in humans.

    Full Text Available Life has significantly altered the Earth's atmosphere, oceans and crust. To what extent has it also affected interior geological processes? To address this question, three models of geological processes are formulated: mantle convection, continental crust uplift and erosion and oceanic crust recycling. These processes are characterised as non-equilibrium thermodynamic systems. Their states of disequilibrium are maintained by the power generated from the dissipation of energy from the interior of the Earth. Altering the thickness of continental crust via weathering and erosion affects the upper mantle temperature which leads to changes in rates of oceanic crust recycling and consequently rates of outgassing of carbon dioxide into the atmosphere. Estimates for the power generated by various elements in the Earth system are shown. This includes, inter alia, surface life generation of 264 TW of power, much greater than those of geological processes such as mantle convection at 12 TW. This high power results from life's ability to harvest energy directly from the sun. Life need only utilise a small fraction of the generated free chemical energy for geochemical transformations at the surface, such as affecting rates of weathering and erosion of continental rocks, in order to affect interior, geological processes. Consequently when assessing the effects of life on Earth, and potentially any planet with a significant biosphere, dynamical models may be required that better capture the coupled nature of biologically-mediated surface and interior processes.

    2011-03-01

    Recent studies have shown that music is capable of conveying semantically meaningful concepts. Several questions have subsequently arisen particularly with regard to the precise mechanisms underlying the communication of musical meaning as well as the role of specific musical features. The present article reports three studies investigating the role of affect expressed by various musical features in priming subsequent word processing at the semantic level. By means of an affective priming paradigm, it was shown that both musically trained and untrained participants evaluated emotional words congruous to the affect expressed by a preceding chord faster than words incongruous to the preceding chord. This behavioral effect was accompanied by an N400, an ERP typically linked with semantic processing, which was specifically modulated by the (mis)match between the prime and the target. This finding was shown for the musical parameter of consonance/dissonance (Experiment 1) and then extended to mode (major/minor) (Experiment 2) and timbre (Experiment 3). Seeing that the N400 is taken to reflect the processing of meaning, the present findings suggest that the emotional expression of single musical features is understood by listeners as such and is probably processed on a level akin to other affective communications (i.e., prosody or vocalizations) because it interferes with subsequent semantic processing. There were no group differences, suggesting that musical expertise does not have an influence on the processing of emotional expression in music and its semantic connotations.

    The catechol-O-methyltransferase (COMT) enzyme is a major determinant of prefrontal dopamine levels. The Val(158)Met polymorphism affects COMT enzymatic activity and has been associated with variation in executive function and affective processing. This study investigated the effect of COMT genotype on the flexible modulation of the balance between processing self-generated and processing stimulus-oriented information, in the presence or absence of affective distractors. Analyses included 124 healthy adult participants, who were also assessed on standard working memory (WM) tasks. Relative to Val carriers, Met homozygotes made fewer errors when selecting and manipulating self-generated thoughts. This effect was partly accounted for by an association between COMT genotype and visuospatial WM performance. We also observed a complex interaction between the influence of affective distractors, COMT genotype and sex on task accuracy: male, but not female, participants showed a sensitivity to the affective distractors that was dependent on COMT genotype. This was not accounted for by WM performance. This study provides novel evidence of the role of dopaminergic genetic variation on the ability to select and manipulate self-generated thoughts. The results also suggest sexually dimorphic effects of COMT genotype on the influence of affective distractors on executive function. © The Author (2014). Published by Oxford University Press.

    It is generally assumed that affective picture viewing is related to higher levels of physiological arousal than is the reading of emotional words. However, this assertion is based mainly on studies in which the processing of either words or pictures has been investigated under heterogenic conditions. Positive, negative, relaxing, neutral, and background (stimulus fragments) words and pictures were presented to subjects in two experiments under equivalent experimental conditions. In Experiment 1, neutral words elicited an enhanced late positive component (LPC) that was associated with an increased difficulty in discriminating neutral from background stimuli. In Experiment 2, high-arousing pictures elicited an enhanced early negativity and LPC that were related to a facilitated processing for these stimuli. Thus, it seems that under some circumstances, the processing of affective information captures attention only with more biologically relevant stimuli. Also, these data might be better interpreted on the basis of those models that postulate a different access to affective information for words and pictures.

  12. The Effect of Positive Mood on Flexible Processing of Affective Information.

    Recent efforts have been made to understand the cognitive mechanisms underlying psychological resilience. Cognitive flexibility in the context of affective information has been related to individual differences in resilience. However, it is unclear whether flexible affective processing is sensitive to mood fluctuations. Furthermore, it remains to be investigated how effects on flexible affective processing interact with the affective valence of information that is presented. To fill this gap, we tested the effects of positive mood and individual differences in self-reported resilience on affective flexibility, using a task switching paradigm (N = 80). The main findings showed that positive mood was related to lower task switching costs, reflecting increased flexibility, in line with previous findings. In line with this effect of positive mood, we showed that greater resilience levels, specifically levels of acceptance of self and life, also facilitated task set switching in the context of affective information. However, the effects of resilience on affective flexibility seem more complex. Resilience tended to relate to more efficient task switching when negative information was preceded by positive information, possibly because the presentation of positive information, as well as positive mood, can facilitate task set switching. Positive mood also influenced costs associated with switching affective valence of the presented information. This latter effect was indicative of a reduced impact of no longer relevant negative information and more impact of no longer relevant positive information. Future research should confirm these effects of individual differences in resilience on affective flexibility, considering the affective valence of the presented information.

  13. Visual and associated affective processing of face information in schizophrenia: A selective review.

    Science.gov (United States)

    Chen, Yue; Ekstrom, Tor

    Perception of facial features is crucial in social life. In past decades, extensive research showed that the ability to perceive facial emotion expression was compromised in schizophrenia patients. Given that face perception involves visual/cognitive and affective processing, the roles of these two processing domains in the compromised face perception in schizophrenia were studied and discussed, but not clearly defined. One particular issue was whether face-specific processing is implicated in this psychiatric disorder. Recent investigations have probed into the components of face perception processes such as visual detection, identity recognition, emotion expression discrimination and working memory conveyed from faces. Recent investigations have further assessed the associations between face processing and basic visual processing and between face processing and social cognitive processing such as Theory of Mind. In this selective review, we discuss the investigative findings relevant to the issues of cognitive and affective association and face-specific processing. We highlight the implications of multiple processing domains and face-specific processes as potential mechanisms underlying compromised face perception in schizophrenia. These findings suggest a need for a domain-specific therapeutic approach to the improvement of face perception in schizophrenia.

    Many nurse-researchers using qualitative strategies have been concerned with assuring quality in their work. The early literature reveals that the concepts of validity and reliability, as understood from the positivist perspective, are somehow inappropriate and inadequate when applied to interpretive research. More recent literature suggests that because of the positivist and interpretive paradigms are epistemologically divergent, the transfer of quality criteria from one perspective to the other is not automatic or even reasonable. The purpose of this article, therefore, is to clarify what the terms quality, trustworthiness, credibility, authenticity, and goodness mean in qualitative research findings. The process of assuring quality, validation, in qualitative research will be discussed within the context of the interpretive method, narrative analysis. A brief review of quality in narrative analysis nursing research will also be presented.

    2009-01-01

    Process-affected water from oil sands production plants presents a major environmental challenge to oil sands operators due to its toxicity to different organisms as well as its corrosiveness in refinery units. This abstract investigated the use of fluorescence excitation-emission matrices to detect and characterize changes in naphthenic acid in oil sands process-affected waters. Samples from oil sands production plants and storage ponds were tested. The study showed that oil sands naphthenic acids show characteristic fluorescence signatures when excited by ultraviolet light in the range of 260 to 350 mm. The signal was a unique attribute of the naphthenic acid molecule. Changes in the fluorescence signature can be used to determine chemical changes such as degradation or aging. It was concluded that the technology can be used as a non-invasive continuous water quality monitoring tool to increase process control in oil sands processing plants

    2010-12-01

    We investigated whether different modes of decision making (deliberate, intuitive, distracted) affect subsequent confirmatory processing of decision-consistent and inconsistent information. Participants showed higher levels of confirmatory information processing when they made a deliberate or an intuitive decision versus a decision under distraction (Studies 1 and 2). As soon as participants have a cognitive (i.e., deliberate cognitive analysis) or affective (i.e., intuitive and gut feeling) reason for their decision, the subjective confidence in the validity of their decision increases, which results in increased levels of confirmatory information processing (Study 2). In contrast, when participants are distracted during decision making, they are less certain about the validity of their decision and thus are subsequently more balanced in the processing of decision-relevant information.

    2015-06-01

    Narrative medicine strives toward a humanized form of medicine in which empathy and the ability to listen are developed with the same emphasis as scientific rigor. We hypothesize that the adoption of narrative medicine in dentistry would be an excellent method to cultivate the philosophy behind the emerging clinical concept of patient-centered dentistry. Reading literary works, reflective writing, and creative writing would sensitize practitioners to the daily lives of people, human uniqueness, and alterity. Narrative dentistry could lead to more empathic and self-aware practices, and improve dental professionals' observational abilities by making them more perceptive and more attentive to image, metaphor, and meaning. The introduction of narrative dentistry would enrich the clinical clerkship of dentists by bringing the often-missing humanities to the dental professional, academic, and scientific environment.

    Full Text Available This article describes a qualitative study that investigated critical reflection in the hope that effective learning is objectified. It is the fruit of rumination on how critical reflection approach would affect learners’ performance in narrative writing. The idea for this paper arose when the researchers consistently utilized ploys effective for five EFL students’ learning of narrative writing in critical reflection process in an institute. Later, these ploys were categorized in three themes under three categories in teaching narrative writing. Data were gathered via students’ reflective writings. Gathered data were interpreted in the real setting by small scale grounded theory analysis. The final upshot demonstrated the criticality of students’ thoughts in their paper. The findings reveal the significance of optimal rapport and intimacy in which participants move ahead from mechanical learning to more cooperative approach in language learning with thorough reflection in their narrations for effective learning to take place.

    Drawing upon a relatively understudied population and a unique observational task, the current study sought to examine how older couples' interactional behaviors during a relationship narrative task were associated with marital satisfaction over time. Using observational data from a sample of 64 older, higher-functioning married couples, we analyzed a series of Actor-Partner Independence Models (APIM) to explore how couples' interactional behaviors during a relationship narrative task were associated with spouses' marital satisfaction both concurrently and one year later. Analyses revealed that spouses' behaviors (e.g., expressions of positive affect, negative affect, communication skills, engagement) were associated with their self-reported marital satisfaction both at the time of the narrative and with changes in marital satisfaction. We found particularly robust evidence for the role of husbands' negative affect during the narrative task in predicting changes in both spouses' marital satisfaction over time. Our results indicate that researchers and clinicians should carefully consider the influence of development on the associations between spouses' behaviors and marital satisfaction. Further, those seeking to improve marriages in later life may need to consider the meaningful role that gender appears to play in shaping the marital experiences of older couples. © 2016 Family Process Institute.

  4. Harm avoidance in adolescents modulates late positive potentials during affective picture processing.

    2013-08-01

    Research in adults has shown that individual differences in harm avoidance (HA) modulate electrophysiological responses to affective stimuli. To determine whether HA in adolescents modulates affective information processing, we collected event-related potentials from 70 adolescents while they viewed 90 pictures from the Chinese affective picture system. Multiple regressions revealed that HA negatively predicted late positive potential (LPP) for positive pictures and positively predicted for negative pictures; however, HA did not correlate with LPP for neutral pictures. The results suggest that at the late evaluative stage, high-HA adolescents display attentional bias to negative pictures while low-HA adolescents display attentional bias to negative pictures. Moreover, these dissociable attentional patterns imply that individual differences in adolescents' HA modulate the late selective attention mechanism of affective information. Copyright © 2013.

  8. Affective picture processing and motivational relevance: arousal and valence effects on ERPs in an oddball task.

    Briggs, Kate E; Martin, Frances H

    2009-06-01

    There are two dominant theories of affective picture processing; one that attention is more deeply engaged by motivationally relevant stimuli (i.e., stimuli that activate both the appetitive and aversive systems), and two that attention is more deeply engaged by aversive stimuli described as the negativity bias. In order to identify the theory that can best account for affective picture processing, event-related potentials (ERPs) were recorded from 34 participants during a modified oddball paradigm in which levels of stimulus valence, arousal, and motivational relevance were systematically varied. Results were partially consistent with motivated attention models of emotional perception, as P3b amplitude was enhanced in response to highly arousing and motivationally relevant sexual and unpleasant stimuli compared to respective low arousing and less motivationally relevant stimuli. However P3b amplitudes were significantly larger in response to the highly arousing sexual stimuli compared to all other affective stimuli, which is not consistent with either dominant theory. The current study therefore highlights the need for a revised model of affective picture processing and provides a platform for further research investigating the independent effects of sexual arousal on cognitive processing.

    Narcissism has significant interpersonal costs, yet little research has examined behavioral and affective patterns characteristic of narcissism in naturalistic settings. Here we studied the effect of narcissistic features on the dynamic processes of interpersonal behavior and affect in daily life. We used interpersonal theory to generate transactional models of social interaction (i.e., linkages among perceptions of others' behavior, affect, and one's own behavior) predicted to be characteristic of narcissism. Psychiatric outpatients (N = 102) completed clinical interviews and a 21-day ecological momentary assessment protocol using smartphones. After social interactions (N = 5,781), participants reported on perceptions of their interaction partner's behavior (scored along the dimensions of dominant-submissive and affiliative-quarrelsome), their own affect, and their own behavior. Multilevel structural equation modeling was used to examine dynamic links among behavior and affect across interactions, and the role of narcissism in moderating these links. Results showed that perceptions of others' dominance did not predict dominant behavior, but did predict quarrelsome behavior, and this link was potentiated by narcissism. Furthermore, the link between others' dominance and one's own quarrelsome behavior was mediated by negative affect. Moderated mediation was also found: Narcissism amplified the link between ratings of others' dominance and one's own quarrelsomeness and negative affect. Narcissism did not moderate the link between other dominance and own dominance, nor the link between other affiliation and own affiliation. These results suggest that narcissism is associated with specific interpersonal and affective processes, such that sensitivity to others' dominance triggers antagonistic behavior in daily life.

    To examine the impacts of Seattle's minimum wage ordinance on food prices by food processing category. Supermarket food prices were collected for 106 items using a University of Washington Center for Public Health Nutrition market basket at affected and unaffected supermarket chain stores at three times: March 2015 (1-month pre-policy enactment), May 2015 (1-month post-policy enactment) and May 2016 (1-year post-policy enactment). Food items were categorized into four food processing groups, from minimally to ultra-processed. Data were analysed across time using a multilevel, linear difference-in-differences model at the store and price level stratified by level of food processing. Six large supermarket chain stores located in Seattle ('intervention') affected by the policy and six same-chain but unaffected stores in King County ('control'), Washington, USA. One hundred and six food and beverage items. The largest change in average price by food item was +$US 0·53 for 'processed foods' in King County between 1-month post-policy and 1-year post-policy enactment (P food processing level strata in Seattle v. King County stores at 1-month or 1-year post-policy enactment.

    Full Text Available Research on narrative persuasion has yet to investigate whether this process influences behavior. The current study explored whether: 1 a narrative could persuade participants to donate to a charity, a prosocial, behavioral decision; 2 psychophysiological metrics can delineate the differences between donation/non-donation behaviors; and 3 donation behavior can be correlated with measures of psychophysiology, self-reported reactions to the narrative, and intrinsic characteristics. Participants (n = 49 completed personality/disposition questionnaires, viewed one of two versions of a narrative while EEG and ECG were recorded, completed a questionnaire regarding their reactions to the narrative, and were given an opportunity to donate to a charity related to the themes of the narrative. Results showed that 1 34.7% of participants donated; 2 psychophysiological metrics successfully delineated between donation behaviors and the effects of narrative version; and 3 psychophysiology and reactions to the narrative were better able to explain the variance (88% and 65%, respectively in the amount donated than all 3 metrics combined as well as any metric alone. These findings demonstrate the promise of narrative persuasion for influencing prosocial, behavioral decisions. Our results also illustrate the utility of the previously stated metrics for understanding and possibly even manipulating behaviors resulting from narrative persuasion.

    The author used the remember/know paradigm and the dual process recognition model of A. P. Yonelinas, N. E. A. Kroll, I. Dobbins, M. Lazzara, and R. T. Knight (1998) to study the states of awareness accompanying recognition of affective images and the processes of recollection and familiarity that may underlie them. Results from all experiments showed that (a) negative stimuli tended to be remembered, whereas positive stimuli tended to be known; (b) recollection, but not familiarity, was boosted for negative or highly arousing and, to a lesser extent, positive stimuli; and (c) across experiments, variations in depth of encoding did not influence these patterns. These data suggest that greater recollection for affective events leads them to be more richly experienced in memory, and they are consistent with the idea that the states of remembering and knowing are experientially exclusive, whereas the processes underlying them are functionally independent.

    The juice used to make white wine can be extracted using various physical processes that affect the amount and timing of contact of juice with skins. The influence of juice extraction processes on the mouthfeel and taste of white wine and their relationship to wine composition were determined. The amount and type of interaction of juice with skins affected both wine total phenolic concentration and phenolic composition. Wine pH strongly influenced perceived viscosity, astringency/drying, and acidity. Despite a 5-fold variation in total phenolics among wines, differences in bitter taste were small. Perceived viscosity was associated with higher phenolics but was not associated with either glycerol or polysaccharide concentration. Bitterness may be reduced by using juice extraction and handling processes that minimize phenolic concentration, but lowering phenolic concentration may also result in wines of lower perceived viscosity.

  17. Protein Molecular Structures, Protein SubFractions, and Protein Availability Affected by Heat Processing: A Review

    International Nuclear Information System (INIS)

    Yu, P.

    2007-01-01

    The utilization and availability of protein depended on the types of protein and their specific susceptibility to enzymatic hydrolysis (inhibitory activities) in the gastrointestine and was highly associated with protein molecular structures. Studying internal protein structure and protein subfraction profiles leaded to an understanding of the components that make up a whole protein. An understanding of the molecular structure of the whole protein was often vital to understanding its digestive behavior and nutritive value in animals. In this review, recently obtained information on protein molecular structural effects of heat processing was reviewed, in relation to protein characteristics affecting digestive behavior and nutrient utilization and availability. The emphasis of this review was on (1) using the newly advanced synchrotron technology (S-FTIR) as a novel approach to reveal protein molecular chemistry affected by heat processing within intact plant tissues; (2) revealing the effects of heat processing on the profile changes of protein subfractions associated with digestive behaviors and kinetics manipulated by heat processing; (3) prediction of the changes of protein availability and supply after heat processing, using the advanced DVE/OEB and NRC-2001 models, and (4) obtaining information on optimal processing conditions of protein as intestinal protein source to achieve target values for potential high net absorbable protein in the small intestine. The information described in this article may give better insight in the mechanisms involved and the intrinsic protein molecular structural changes occurring upon processing.

  18. Selective attention to affective value alters how the brain processes olfactory stimuli.

    Rolls, Edmund T; Grabenhorst, Fabian; Margot, Christian; da Silva, Maria A A P; Velazco, Maria Ines

    2008-10-01

    How does selective attention to affect influence sensory processing? In a functional magnetic resonance imaging investigation, when subjects were instructed to remember and rate the pleasantness of a jasmine odor, activations were greater in the medial orbito-frontal and pregenual cingulate cortex than when subjects were instructed to remember and rate the intensity of the odor. When the subjects were instructed to remember and rate the intensity, activations were greater in the inferior frontal gyrus. These top-down effects occurred not only during odor delivery but started in a preparation period after the instruction before odor delivery, and continued after termination of the odor in a short-term memory period. Thus, depending on the context in which odors are presented and whether affect is relevant, the brain prepares itself, responds to, and remembers an odor differently. These findings show that when attention is paid to affective value, the brain systems engaged to prepare for, represent, and remember a sensory stimulus are different from those engaged when attention is directed to the physical properties of a stimulus such as its intensity. This differential biasing of brain regions engaged in processing a sensory stimulus depending on whether the cognitive demand is for affect-related versus more sensory-related processing may be an important aspect of cognition and attention. This has many implications for understanding the effects not only of olfactory but also of other sensory stimuli.

SFA, PEP, and biased performance appraisals are related to social anxiety; however, limited research has examined how SFA affects information-processing following social events. The current study examined whether SFA affects the relationships between performance appraisals and PEP following a social event.. 137 participants with high (n = 72) or low (n = 65) social anxiety were randomly assigned to conditions of high SFA or low SFA while engaging in a standardized social performance. Subsequent performance appraisals and PEP were measured. Immediate performance appraisals were not affected by SFA. High levels of SFA led to a stronger, inverse relationship between immediate positive performance appraisals and subsequent negative PEP. High levels of SFA also led to a stronger, inverse relationship between negative PEP and changes in positive performance appraisals.. Future research should examine whether the current findings, which involved a standardized social performance event, extend to interaction events as well as in a clinical sample. These findings suggest that SFA affects the processing of positive information following a social performance event. SFA is particularly important for understanding how negative PEP undermines positive performance appraisals.. Published by Elsevier Ltd.

    Research suggests that cancer patients who are more involved in treatment decision-making (TDM) report better quality of life following treatment. This study examines the association and possible mechanisms between prostate cancer patient's discussions about TDM and affect following treatment. We predicted that the length of time patients spent discussing treatment options with social networks and physicians prior to treatment would predict emotional adjustment after treatment. We further predicted that cognitive processing, coping, and patient understanding of treatment options would mediate this association. Fifty-seven patients completed questionnaires prior to treatment and at 1 and 6 months following treatment completion. Findings from the present study suggest that discussing treatment options with others, prior to beginning treatment for prostate cancer, significantly contributed to improvements in affect 1 and 6 months following treatment. Residualized regression analyses indicated that discussing treatment options with patient's social networks predicted a decrease in negative affect 1 and 6 months following treatment, while discussions with physicians predicted an increase in positive affect 1 month following treatment. Patients who spent more time discussing treatment options with family and friends also reported greater pre-treatment social support and emotional expression. Mediation analyses indicated that these coping strategies facilitated cognitive processing (as measured by a decrease in intrusive thoughts) and that cognitive processing predicted improvement in affect. Greater time spent talking with family and friends about treatment options may provide opportunities for patients to cope with their cancer diagnosis and facilitate cognitive processing, which may improve patient distress over time.

    Full Text Available According to attribution models of familiarity assessment, people can use a heuristic in recognition-memory decisions, in which they attribute the subjective ease of processing of a memory probe to a prior encounter with the stimulus in question. Research in social cognition suggests that experienced positive affect may be the proximal cue that signals fluency in various experimental contexts. In the present study, we compared the effects of positive affect and fluency on recognition-memory judgments for faces with neutral emotional expression. We predicted that if positive affect is indeed the critical cue that signals processing fluency at retrieval, then its manipulation should produce effects that closely mirror those produced by manipulations of processing fluency. In two experiments, we employed a masked-priming procedure in combination with a Remember-Know paradigm that aimed to separate familiarity- from recollection-based memory decisions. In addition, participants performed a prime-discrimination task that allowed us to take inter-individual differences in prime awareness into account. We found highly similar effects of our priming manipulations of processing fluency and of positive affect. In both cases, the critical effect was specific to familiarity-based recognition responses. Moreover, in both experiments it was reflected in a shift towards a more liberal response bias, rather than in changed discrimination. Finally, in both experiments, the effect was found to be related to prime awareness; it was present only in participants who reported a lack of such awareness on the prime-discrimination task. These findings add to a growing body of evidence that points not only to a role of fluency, but also of positive affect in familiarity assessment. As such they are consistent with the idea that fluency itself may be hedonically marked.

  4. Narrative Construction, Social Perceptions, and the Situation Model.

    2016-05-01

    The present investigation examined how three salient features of narrative thinking (situation model construction, linguistic concreteness, and perspective-taking) influenced the social inference process. Results of four experiments indicated that compared with those given other objectives, perceivers given narrative objectives were: (a) more likely to make situation rather than trait attributions for observed behaviors (Experiment 1), (b) less likely to make implicit trait inferences (Experiment 2), and (c) less likely to rely on behavior valence when making evaluative judgments (Experiment 4). Linguistic analyses indicated that narrative construction consistently entailed the creation of situation models of events and linguistic concreteness, but only situation model creation mediated the relationship between narrative and inferences. Experiment 3 confirmed the mediating role of situation models: Perceivers with narrative objectives made trait inferences only when behaviors were inconsistent with contextual information. The role of these core narrative features on social perceptions is discussed. © 2016 by the Society for Personality and Social Psychology, Inc.

    Full Text Available A story is one of the forms of human communication, and one of the oldest ways of understanding the world and exchanging knowledge. The story is told through words, images and movement, and therefore the phenomenon of narration cannot be limited to verbal expression only. One can narrate about real or imaginary events in order to convey a message, provide knowledge or entertainment, and also to create an art form as well as achieve aesthetic communication. The process by means of which the inner world is built within a literary work is certainly the story or narrative. Modern theory of narration enumerates a number of forms of narration indifferent media: in folklore and art, oral or written linguistic narrative form, in pantomime, picture, vitrage, and film. This paper discusses various contemporary narratological ideas.

    To examine the neural basis and dynamics of facial affect processing in schizophrenic patients as compared to healthy controls. Fourteen schizophrenic patients and fourteen matched controls performed a facial affect identification task during fMRI acquisition. The emotional task included an intuitive emotional condition (matching emotional faces) and a more cognitively demanding condition (labeling emotional faces). Individual analysis for each emotional condition, and second-level t-tests examining both within-, and between-group differences, were carried out using a random effects approach. Psychophysiological interactions (PPI) were tested for variations in functional connectivity between amygdala and other brain regions as a function of changes in experimental conditions (labeling versus matching). During the labeling condition, both groups engaged similar networks. During the matching condition, schizophrenics failed to activate regions of the limbic system implicated in the automatic processing of emotions. PPI revealed an inverse functional connectivity between prefrontal regions and the left amygdala in healthy volunteers but there was no such change in patients. Furthermore, during the matching condition, and compared to controls, patients showed decreased activation of regions involved in holistic face processing (fusiform gyrus) and increased activation of regions associated with feature analysis (inferior parietal cortex, left middle temporal lobe, right precuneus). Our findings suggest that schizophrenic patients invariably adopt a cognitive approach when identifying facial affect. The distributed neocortical network observed during the intuitive condition indicates that patients may resort to feature-based, rather than configuration-based, processing and may constitute a compensatory strategy for limbic dysfunction.

    Aquatic plants such as cattail contribute substantially to the energy flow in wetlands. Since Typha (cattail) plants acquire and cycle carbon and nutrients through wetlands, their growth and recycling of captured nutrients are an important part of natural, healthy wetland ecosystems. Cattail are pervasive and satisfy many of the criteria to be used as indicators of wetland integrity. This study investigated if cattail growth and carbon accrual were influenced by oil sands process materials (OSPM) such as consolidated tailings (CT). The purpose was to facilitate land reclamation initiatives by evaluating the impact that constituents of oil sands process material have on aquatic plant growth. The study was conducted at Suncor's experimental trenches. Six lined basins were used, of which 3 were filled with natural water and 3 were filled with trench water. Cattail were planted in different growth medium combinations, including CT over CT; soil over soil; soil over CT; and soil over sterilized sand. All leaf lengths and widths were measured along with the photosynthesis of the leaves and root and plant biomass at planting and after 2-years growth. A larger leaf area was observed under oil sands process influence, which may indicate increased carbon accrual above ground. Leaf area data suggested that CT affected plants are quite productive. The study also indicated that oil sands affected water may reduce plant fitness, and therefore could influence the overall oil sands reclamation timelines. Conversely, cattail grown in soil capped process affected material had a much larger leaf area compared to those grown in soil capped sand, most likely due to the higher levels of ammonia in process affected material.

  9. Differential Contribution of Right and Left Amygdala to Affective Information Processing

    Directory of Open Access Journals (Sweden)

    1999-01-01

    Full Text Available Evidence for a differential involvement of the human left and right amygdala in emotional and cognitive behaviour is reviewed, with a particular emphasis on functional imaging results and case reports on patients with amygdalar damage. The available evidence allows one to conclude that there is definitely a hemisphere specific processing difference between the left and right amygdala. However, between studies the direction of the asymmetry is partly incongruent. In spite of this, the following tentative proposals are made: the left amygdala is more closely related to affective information encoding with a higher affinity to language and to detailed feature extraction, and the right amygdala to affective information retrieval with a higher affinity to pictorial or image-related material. Furthermore, the right amygdala may be more strongly engaged than the left one in a fast, shallow or gross analysis of affect-related information.

  10. Extraversion and reward-related processing: probing incentive motivation in affective priming tasks.

    Robinson, Michael D; Moeller, Sara K; Ode, Scott

    2010-10-01

    Based on an incentive motivation theory of extraversion (Depue & Collins, 1999), it was hypothesized that extraverts (relative to introverts) would exhibit stronger positive priming effects in affective priming tasks, whether involving words or pictures. This hypothesis was systematically supported in four studies involving 229 undergraduates. In each of the four studies, and in a subsequent combined analysis, extraversion was positively predictive of positive affective priming effects, but was not predictive of negative affective priming effects. The results bridge an important gap in the literature between biological and trait models of incentive motivation and do so in a way that should be informative to subsequent efforts to understand the processing basis of extraversion as well as incentive motivation.

    2012-12-01

    Individual affect-related performance zones (IAPZs) method utilizing Kamata et al. (J Sport Exerc Psychol 24:189-208, 2002) probabilistic model of determining the individual zone of optimal functioning was utilized as idiosyncratic affective patterns during golf performance. To do so, three male golfers of a varsity golf team were observed during three rounds of golf competition. The investigation implemented a multi-modal assessment approach in which the probabilistic relationship between affective states and both, performance process and performance outcome, measures were determined. More specifically, introspective (i.e., verbal reports) and objective (heart rate and respiration rate) measures of arousal were incorporated to examine the relationships between arousal states and both, process components (i.e., routine consistency, timing), and outcome scores related to golf performance. Results revealed distinguishable and idiosyncratic IAPZs associated with physiological and introspective measures for each golfer. The associations between the IAPZs and decision-making or swing/stroke execution were strong and unique for each golfer. Results are elaborated using cognitive and affect-related concepts, and applications for practitioners are provided.

  12. Advancing the Assessment of Personality Pathology With the Cognitive-Affective Processing System.

    Huprich, Steven K; Nelson, Sharon M

    2015-01-01

    The Cognitive-Affective Processing System (CAPS) is a dynamic and expansive model of personality proposed by Mischel and Shoda (1995) that incorporates dispositional and processing frameworks by considering the interaction of the individual and the situation, and the patterns of variation that result. These patterns of cognition, affect, and behavior are generally defined through the use of if … then statements, and provide a rich understanding of the individual across varying levels of assessment. In this article, we describe the CAPS model and articulate ways in which it can be applied to conceptualizing and assessing personality pathology. We suggest that the CAPS model is an ideal framework that integrates a number of current theories of personality pathology, and simultaneously overcomes a number of limits that have been empirically identified in the past.

    2011-12-01

    Narrative visualizations combine conventions of communicative and exploratory information visualization to convey an intended story. We demonstrate visualization rhetoric as an analytical framework for understanding how design techniques that prioritize particular interpretations in visualizations that "tell a story" can significantly affect end-user interpretation. We draw a parallel between narrative visualization interpretation and evidence from framing studies in political messaging, decision-making, and literary studies. Devices for understanding the rhetorical nature of narrative information visualizations are presented, informed by the rigorous application of concepts from critical theory, semiotics, journalism, and political theory. We draw attention to how design tactics represent additions or omissions of information at various levels-the data, visual representation, textual annotations, and interactivity-and how visualizations denote and connote phenomena with reference to unstated viewing conventions and codes. Classes of rhetorical techniques identified via a systematic analysis of recent narrative visualizations are presented, and characterized according to their rhetorical contribution to the visualization. We describe how designers and researchers can benefit from the potentially positive aspects of visualization rhetoric in designing engaging, layered narrative visualizations and how our framework can shed light on how a visualization design prioritizes specific interpretations. We identify areas where future inquiry into visualization rhetoric can improve understanding of visualization interpretation. © 2011 IEEE

  14. Integrative processing of touch and affect in social perception: an fMRI study

    2016-05-01

    Full Text Available Social perception commonly employs multiple sources of information. The present study aimed at investigating the integrative processing of affective social signals. Task-related and task-free functional magnetic resonance imaging was performed in 26 healthy adult participants during a social perception task concerning dynamic visual stimuli simultaneously depicting facial expressions of emotion and tactile sensations that could be either congruent or incongruent. Confounding effects due to affective valence, inhibitory top-down influences, cross-modal integration, and conflict processing were minimized. The results showed that the perception of congruent, compared to incongruent stimuli, elicited enhanced neural activity in a set of brain regions including left amygdala, bilateral posterior cingulate cortex (PCC, and left superior parietal cortex. These congruency effects did not differ as a function of emotion or sensation. A complementary task-related functional interaction analysis preliminarily suggested that amygdala activity depended on previous processing stages in fusiform gyrus and PCC. The findings provide support for the integrative processing of social information about others' feelings from manifold bodily sources (sensory-affective information in amygdala and PCC. Given that the congruent stimuli were also judged as being more self-related and more familiar in terms of personal experience in an independent sample of participants, we speculate that such integrative processing might be mediated by the linking of external stimuli with self-experience. Finally, the prediction of task-related responses in amygdala by intrinsic functional connectivity between amygdala and PCC during a task-free state implies a neuro-functional basis for an individual predisposition for the integrative processing of social stimulus content.

    2004-11-01

    Full Text Available Various process parameters affecting eucalyptus kraft pulp delignification with peroxyacetic acid were investigated. The results showed that pH was an important factor. The delignification rate increased with increasing pH to the value of 6. High delignification rate was obtained when the pulp was chelated with Na4-EDTA prior to the peroxyacetic acid stage. Therefore, delignification reaction rate depends on peroxyacid charge, temperature, pH and metal content of pulp.

    2010-01-01

    Full Text Available The aim of this study was to investigate the relationship between cognitive processing of affective verbal material and the basic personality structure. For the purposes of research a new experiment was created, where affective priming was measured in a lexical decision task. The term affective priming stands for facilitation in recognition of the stimuli that comes after the presentation of stimuli of the same valence. In this experiment, two words were presented on a screen in front of the subject (stimuli-prime and stimuli-target. Those two words were of the same or different affective valence, and the subject's were instructed to respond whether the second word on the screen had a meaning or not. The basic personality structure was defined by the 'Big five' model and the Disintegration model and measured by NEO PI-R and Delta 10 questionnaires. The results of the affective priming experiment indicated a strong effect of positive facilitation and much weaker effect off negative facilitation. Two significant functions were extracted by quasicanonical correlation analysis. The first function showed correlation between the effect of positive facilitation and all of the subscales of Neuroticism, Extraversion and Conscientiousness (NEO PI-R, as well as all sub dimensions of Disintegration (DELTA 10. The second one indicated to a correlation between the negative facilitation effect and some subscales of Neuroticism, Extraversion and Agreeableness (NEO PI-R, as well as all subscales of Disintegration (DELTA 10.

    The cell provisioning and oviposition process (POP) is a unique characteristic of stingless bees (Meliponini), in which coordinated interactions between workers and queen regulate the filling of brood cells with larval resources and subsequent egg laying. Environmental conditions seem to regulate reproduction in stingless bees; however, little is known about how the amount of food affects quantitative sequences of the process. We examined intrinsic variables by comparing three colonies in distinct conditions (strong, intermediate and weak state). We predicted that some of these variables are correlated with temporal events of POP in Melipona scutellaris colonies. The results demonstrated that the strong colony had shorter periods of POP.

    2015-08-01

    Narrative messages are increasingly popular in health and risk campaigns, yet gain/loss framing effects have never been tested with such messages. Three experiments examined framing in narrative messages. Experiment 1 found that only the character's decision, not framing, influenced judgments about characters in a narrative derived from a prospect theory context. Experiment 2 found that a framing effect that occurred when presented in a decision format did not occur when the same situation was presented as a narrative. Using a different story/decision context, Experiment 3 found no significant difference in preference for surgery over radiation therapy in a narrative presentation compared to a non-narrative presentation. The results suggest that health and risk campaigns cannot assume that framing effects will be the same in narrative messages and non-narrative messages. Potential reasons for these differences and suggestions for future research are discussed. © 2015 Society for Risk Analysis.

    Full Text Available Decision-making involves a complex interplay of emotional responses and reasoning processes. In this study, we use TMS to explore the neurobiological substrates of moral decisions in humans. To examining the effects of TMS on the outcome of a moral-decision, we compare the decision outcome of moral-personal and moral-impersonal dilemmas to each other and examine the differential effects of applying TMS over the right DLPFC or right TPJ. In this comparison, we find that the TMS-induced disruption of the DLPFC during the decision process, affects the outcome of the moral-personal judgment, while TMS-induced disruption of TPJ affects only moral-impersonal conditions. In other words, we find a double-dissociation between DLPFC and TPJ in the outcome of a moral decision. Furthermore, we find that TMS-induced disruption of the DLPFC during non-moral, moral-impersonal, and moral-personal decisions lead to lower ratings of regret about the decision. Our results are in line with the dual-process theory and suggest a role for both the emotional response and cognitive reasoning process in moral judgment. Both the emotional and cognitive processes were shown to be involved in the decision outcome.

    Waldron, M.C.; Wiley, J.B.

    1996-01-01

    The water quality and environmental processes affecting dissolved oxygen were determined for the Blackwater River in Canaan Valley, West Virginia. Canaan Valley is oval-shaped (14 miles by 5 miles) and is located in the Allegheny Mountains at an average elevation of 3,200 feet above sea level. Tourism, population, and real estate development have increased in the past two decades. Most streams in Canaan Valley are a dilute calcium magnesium bicarbonate-type water. Streamwater typicaly was soft and low in alkalinity and dissolved solids. Maximum values for specific conductance, hardness, alkalinity, and dissolved solids occurred during low-flow periods when streamflow was at or near baseflow. Dissolved oxygen concentrations are most sensitive to processes affecting the rate of reaeration. The reaeration is affected by solubility (atmospheric pressure, water temperature, humidity, and cloud cover) and processes that determine stream turbulence (stream depth, width, velocity, and roughness). In the headwaters, photosynthetic dissolved oxygen production by benthic algae can result in supersaturated dissolved oxygen concentrations. In beaver pools, dissolved oxygen consumption from sediment oxygen demand and carbonaceous biochemical oxygen demand can result in dissolved oxygen deficits.

  11. A narrative method for consciousness research

    Díaz, José-Luis

    2013-01-01

    Some types of first-person narrations of mental processes that constitute phenomenological accounts and texts, such as internal monolog statements, epitomize the best expressions and representations of human consciousness available and therefore may be used to model phenomenological streams of consciousness. The type of autonomous monolog in which an author or narrator declares actual mental processes in a think aloud manner seems particularly suitable for modeling streams of consciousness. A narrative method to extract and depict conscious processes, operations, contents, and states from an acceptable phenomenological text would require three subsequent steps: operational criteria for producing and/or selecting a phenomenological text, a system for detecting text items that are indicative of conscious contents and processes, and a procedure for representing such items in formal dynamic system devices such as Petri nets. The requirements and restrictions of each of these steps are presented, analyzed, and applied to phenomenological texts in the following manner: (1) the relevance of introspective language and narrative analyses to consciousness research and the idea that specific narratives are of paramount interest for such investigation is justified; (2) some of the obstacles and constraints to attain plausible consciousness inferences from narrative texts and the methodological requirements to extract and depict items relevant to consciousness contents and operations from a suitable phenomenological text are examined; (3) a preliminary exercise of the proposed method is used to analyze and chart a classical interior monolog excerpted from James Joyce’s Ulysses, a masterpiece of the stream-of-consciousness literary technique and, finally, (4) an inter-subjective evaluation for inter-observer agreement of mental attributions of another phenomenological text (an excerpt from the Intimate Journal of Miguel de Unamuno) is presented using some mathematical tools

    The present study explored the attentional processing mechanisms of gaze and arrow cues in two different types of conflict tasks. In Experiment 1, participants performed a flanker task in which gaze and arrow cues were presented as central targets or bilateral distractors. The congruency between the direction of the target and the distractors was manipulated. Results showed that arrow distractors greatly interfered with the attentional processing of gaze, while the processing of arrow direction was immune to conflict from gaze distractors. Using a spatial compatibility task, Experiment 2 explored the conflict effects exerted on gaze and arrow processing by their relative spatial locations. When the direction of the arrow was in conflict with its spatial layout on screen, response times were slowed; however, the encoding of gaze was unaffected by spatial location. In general, processing to an arrow cue is less influenced by bilateral gaze cues but is affected by irrelevant spatial information, while processing to a gaze cue is greatly disturbed by bilateral arrows but is unaffected by irrelevant spatial information. Different effects on gaze and arrow cues by different types of conflicts may reflect two relatively distinct specific modes of the attentional process.

    Narratives may be easy to come by, but not everything is worth narrating. What merits a narrative? Here, I follow the lead of narratologists and literary theorists, and focus on one particular proposal concerning the elements of a story that make it narrative-worthy. These elements correspond to features of the natural world addressed by the historical sciences, where narratives figure so prominently. What matters is contingency. Narratives are especially good for representing contingency and accounting for contingent outcomes. This will be squared with a common view that narratives leave no room for chance. On the contrary, I will argue, tracing one path through a maze of alternative possibilities, and alluding to those possibilities along the way, is what a narrative does particularly well.

    2009-06-15

    Impaired emotion recognition has been reported in schizophrenia, yet the nature of this impairment is not completely understood. Recognition of facial emotion depends on processing affective and nonaffective facial signals, as well as basic visual attributes. We examined whether and how poor facial emotion recognition in schizophrenia is related to basic visual processing and nonaffective face recognition. Schizophrenia patients (n = 32) and healthy control subjects (n = 29) performed emotion discrimination, identity discrimination, and visual contrast detection tasks, where the emotionality, distinctiveness of identity, or visual contrast was systematically manipulated. Subjects determined which of two presentations in a trial contained the target: the emotional face for emotion discrimination, a specific individual for identity discrimination, and a sinusoidal grating for contrast detection. Patients had significantly higher thresholds (worse performance) than control subjects for discriminating both fearful and happy faces. Furthermore, patients' poor performance in fear discrimination was predicted by performance in visual detection and face identity discrimination. Schizophrenia patients require greater emotional signal strength to discriminate fearful or happy face images from neutral ones. Deficient emotion recognition in schizophrenia does not appear to be determined solely by affective processing but is also linked to the processing of basic visual and facial information.

    2018-06-01

    Media coverage of mental health and other social issues often relies on episodic narratives that suggest individualistic causes and solutions, while reinforcing negative stereotypes. Community narratives can provide empowering alternatives, serving as media advocacy tools used to shape the policy debate on a social issue. This article provides health promotion researchers and practitioners with guidance on how to develop and disseminate community narratives to broaden awareness of social issues and build support for particular programs and policy solutions. To exemplify the community narrative development process and highlight important considerations, this article examines a narrative from a mental health consumer-run organization. In the narrative, people with mental health problems help one another while operating a nonprofit organization, thereby countering stigmatizing media portrayals of people with mental illness as dangerous and incompetent. The community narrative frame supports the use of consumer-run organizations, which are not well-known and receive little funding despite evidence of effectiveness. The article concludes by reviewing challenges to disseminating community narratives, such as creating a product of interest to media outlets, and potential solutions, such as engaging media representatives through community health partnerships and using social media to draw attention to the narratives.

    To describe the extent of adoption of diabetes care management processes in physician organizations in the U.S. and to investigate the organizational factors that affect the adoption of diabetes care management processes. Data are derived from the National Survey of Physician Organizations and the Management of Chronic Illness, conducted in 2000-2001. A total of 1,104 of the 1,590 physician organizations identified responded to the survey. The extent of adoption of four diabetes care management processes is measured by an index consisting of the organization's use of diabetic patient registries, clinical practice guidelines, case management, and physician feedback. The ordinary least-squares model is used to determine the association of organizational characteristics with the adoption of diabetes care management processes in physician organizations. A logistic regression model is used to determine the association of organizational characteristics with the adoption of individual diabetes care management processes. Of the 987 physician organizations studied that treat patients with diabetes, 48% either do not use any or use only one of the four diabetes care management processes. A total of 20% use two care management processes, and 32% use three or four processes. External incentives to improve quality, computerized clinical information systems, and ownership by hospitals or health maintenance organizations are strongly associated with the diabetes care management index and the adoption of individual diabetes care management processes. Policies to encourage external incentives to improve quality and to facilitate the adoption of computerized clinical information technology may promote greater use of diabetes care management processes.

    This paper explores the contentious notion of experiential narrative and proposes the first step in a narrative framework for game environment. It argues for a shift in emphasis from story-telling, the dominant mode of narrative in literature and cinema, to story generation. To this effect the paper forwards a perspective on experiential narrative that is grounded in the specific qualities of the game. This avoids the over-generalization that tends to accompany discussions of experiential nar...

    Groups often suffer from ineffective communication and decision making. This experimental study compares distributed groups solving a preference task with support from either a communication system or a system providing both communication and a structuring of the decision-making process. Results...... show that groups using the latter system spend more time solving the task, spend more of their time on solution analysis, spend less of their time on disorganized activity, and arrive at task solutions with less extreme preferences. Thus, the type of system affects the decision-making process as well...... as its outcome. Notably, the task solutions arrived at by the groups using the system that imposes a structuring of the decision-making process show limited correlation with the task solutions suggested by the system on the basis of the groups’ explicitly stated criteria.

  2. How does context affect intimate relationships? linking external stress and cognitive processes within marriage.

    Neff, Lisa A; Karney, Benjamin R

    2004-02-01

    Stressors external to the marriage frequently affect the way spouses evaluate their marital quality. To date, however, understanding of the interplay between external stress and internal relationship processes has been limited in two ways. First, research has generally examined only the short-term consequences of stress. Second, the mechanisms through which external stressors influence relationship outcomes are unclear. This study addressed both limitations by examining relationship cognitions that may mediate the effects of external stress throughout 4 years of marriage. Analyses confirmed that stressful experiences were associated with the trajectory of marital quality overtime. Furthermore, both the content and the organization of spouses' specific relationship cognitions mediated this effect. That is, stress negatively influenced the nature of spouses' marital perceptions as well as the way spouses interpreted and processed those perceptions. These findings draw attention to ways that the context of relationships shapes and constrains relationship processes.

  3. Application of ultrasound processed images in space: Quanitative assessment of diffuse affectations

    Pérez-Poch, A.; Bru, C.; Nicolau, C.

    The purpose of this study was to evaluate diffuse affectations in the liver using texture image processing techniques. Ultrasound diagnose equipments are the election of choice to be used in space environments as they are free from hazardous effects on health. However, due to the need for highly trained radiologists to assess the images, this imaging method is mainly applied on focal lesions rather than on non-focal ones. We have conducted a clinical study on 72 patients with different degrees of chronic hepatopaties and a group of control of 18 individuals. All subjects' clinical reports and results of biopsies were compared to the degree of affectation calculated by our computer system , thus validating the method. Full statistical results are given in the present paper showing a good correlation (r=0.61) between pathologist's report and analysis of the heterogenicity of the processed images from the liver. This computer system to analyze diffuse affectations may be used in-situ or via telemedicine to the ground.

  4. Emotional Granularity Effects on Event-Related Brain Potentials during Affective Picture Processing.

    2017-01-01

    There is debate about whether emotional granularity , the tendency to label emotions in a nuanced and specific manner, is merely a product of labeling abilities, or a systematic difference in the experience of emotion during emotionally evocative events. According to the Conceptual Act Theory of Emotion (CAT) (Barrett, 2006), emotional granularity is due to the latter and is a product of on-going temporal differences in how individuals categorize and thus make meaning of their affective states. To address this question, the present study investigated the effects of individual differences in emotional granularity on electroencephalography-based brain activity during the experience of emotion in response to affective images. Event-related potentials (ERP) and event-related desynchronization and synchronization (ERD/ERS) analysis techniques were used. We found that ERP responses during the very early (60-90 ms), middle (270-300 ms), and later (540-570 ms) moments of stimulus presentation were associated with individuals' level of granularity. We also observed that highly granular individuals, compared to lowly granular individuals, exhibited relatively stable desynchronization of alpha power (8-12 Hz) and synchronization of gamma power (30-50 Hz) during the 3 s of stimulus presentation. Overall, our results suggest that emotional granularity is related to differences in neural processing throughout emotional experiences and that high granularity could be associated with access to executive control resources and a more habitual processing of affective stimuli, or a kind of "emotional complexity." Implications for models of emotion are also discussed.

  12. Embodied simulation as part of affective evaluation processes: task dependence of valence concordant EMG activity.

    Science.gov (United States)

    Weinreich, André; Funcke, Jakob Maria

    2014-01-01

    Drawing on recent findings, this study examines whether valence concordant electromyography (EMG) responses can be explained as an unconditional effect of mere stimulus processing or as somatosensory simulation driven by task-dependent processing strategies. While facial EMG over the Corrugator supercilii and the Zygomaticus major was measured, each participant performed two tasks with pictures of album covers. One task was an affective evaluation task and the other was to attribute the album covers to one of five decades. The Embodied Emotion Account predicts that valence concordant EMG is more likely to occur if the task necessitates a somatosensory simulation of the evaluative meaning of stimuli. Results support this prediction with regard to Corrugator supercilii in that valence concordant EMG activity was only present in the affective evaluation task but not in the non-evaluative task. Results for the Zygomaticus major were ambiguous. Our findings are in line with the view that EMG activity is an embodied part of the evaluation process and not a mere physical outcome.

    Lipids play an important role as risk or protective factors in Alzheimer's disease (AD). Previously it has been shown that plasmalogens, the major brain phospholipids, are altered in AD. However, it remained unclear whether plasmalogens themselves are able to modulate amyloid precursor protein (APP) processing or if the reduced plasmalogen level is a consequence of AD. Here we identify the plasmalogens which are altered in human AD postmortem brains and investigate their impact on APP processing resulting in Aβ production. All tested plasmalogen species showed a reduction in γ-secretase activity whereas β- and α-secretase activity mainly remained unchanged. Plasmalogens directly affected γ-secretase activity, protein and RNA level of the secretases were unaffected, pointing towards a direct influence of plasmalogens on γ-secretase activity. Plasmalogens were also able to decrease γ-secretase activity in human postmortem AD brains emphasizing the impact of plasmalogens in AD. In summary our findings show that decreased plasmalogen levels are not only a consequence of AD but that plasmalogens also decrease APP processing by directly affecting γ-secretase activity, resulting in a vicious cycle: Aβ reduces plasmalogen levels and reduced plasmalogen levels directly increase γ-secretase activity leading to an even stronger production of Aβ peptides.

    To compare radiographic elbow arthrosis with arthroscopic cartilage pathology in Labrador retrievers with elbow osteoarthritis secondary to medial coronoid process (MCP) disease. Retrospective epidemiological study. Labrador retrievers (n = 317; 592 elbow joints). Data were collected retrospectively (June 2007-June 2011) to identify Labrador retrievers with thoracic limb lameness and elbow pain, a complete set of elbow radiographs, and a comprehensive arthroscopic surgery report. Each radiograph was scored for osteophytosis on the anconeal process and ulnar subtrochlear sclerosis using a modification of the International Elbow Working Group (IEWG) scoring system. Elbows affected by traumatic MCP fracture, humeral condylar osteochondrosis, or ununited anconeal process were excluded. The arthroscopic report was used to generate a composite cartilage score (CCS; 0 = normal, 1 = mild, 2 = moderate, 3 = severe) for each elbow joint. Ordinal regression analysis was performed to test the relationship between radiographic arthrosis score and CCS. There was a significant relationship between radiographic elbow arthrosis and CCS (P arthrosis can be used to predict the severity of arthroscopic cartilage pathology in Labrador retrievers affected by MCP disease. © Copyright 2014 by The American College of Veterinary Surgeons.

    As part of routine husbandry, an increasing number of laboratory mice receive nesting material in addition to standard bedding material in their cages. Nesting material improves health outcomes and physiological performance in mice that receive it. Providing usable nesting material uniformly and efficiently to various strains of mice remains a challenge. The aim of this study was to determine how bedding particle size, method of nesting material delivery, and processing of the nesting material before delivery affected nest building in mice of strong (BALB/cAnNCrl) and weak (C3H/HeNCrl) gathering abilities. Our data suggest that processing nesting material through a grinder in conjunction with bedding material, although convenient for provision of bedding with nesting material 'built-in', negatively affects the integrity of the nesting material and subsequent nest-building outcomes. We also found that C3H mice, previously thought to be poor nest builders, built similarly scored nests to those of BALB/c mice when provided with unprocessed nesting material. This was true even when nesting material was mixed into the bedding substrate. We also observed that when nesting material was mixed into the bedding substrate, mice of both strains would sort their bedding by particle size more often than if it were not mixed in. Our findings support the utility of the practice of distributing nesting material mixed in with bedding substrate, but not that of processing the nesting material with the bedding in order to mix them.

  17. Transcranial Electrical Stimulation over Dorsolateral Prefrontal Cortex Modulates Processing of Social Cognitive and Affective Information.

    Directory of Open Access Journals (Sweden)

    Massimiliano Conson

    Full Text Available Recent neurofunctional studies suggested that lateral prefrontal cortex is a domain-general cognitive control area modulating computation of social information. Neuropsychological evidence reported dissociations between cognitive and affective components of social cognition. Here, we tested whether performance on social cognitive and affective tasks can be modulated by transcranial direct current stimulation (tDCS over dorsolateral prefrontal cortex (DLPFC. To this aim, we compared the effects of tDCS on explicit recognition of emotional facial expressions (affective task, and on one cognitive task assessing the ability to adopt another person's visual perspective. In a randomized, cross-over design, male and female healthy participants performed the two experimental tasks after bi-hemispheric tDCS (sham, left anodal/right cathodal, and right anodal/left cathodal applied over DLPFC. Results showed that only in male participants explicit recognition of fearful facial expressions was significantly faster after anodal right/cathodal left stimulation with respect to anodal left/cathodal right and sham stimulations. In the visual perspective taking task, instead, anodal right/cathodal left stimulation negatively affected both male and female participants' tendency to adopt another's point of view. These findings demonstrated that concurrent facilitation of right and inhibition of left lateral prefrontal cortex can speed-up males' responses to threatening faces whereas it interferes with the ability to adopt another's viewpoint independently from gender. Thus, stimulation of cognitive control areas can lead to different effects on social cognitive skills depending on the affective vs. cognitive nature of the task, and on the gender-related differences in neural organization of emotion processing.

    Research into recommendation algorithms has made great strides in recent years. However, these algorithms are typically applied in relatively straightforward scenarios: given information about a user's past preferences, what will they like in the future? Recommendation is often more complex......: evaluating recommended items never takes place in a vacuum, and it is often a single step in the user's more complex background task. In this paper, we define a specific type of recommendation scenario called narrative-driven recommendation, where the recommendation process is driven by both a log...... of the user's past transactions as well as a narrative description of their current interest(s). Through an analysis of a set of real-world recommendation narratives from the LibraryThing forums, we demonstrate the uniqueness and richness of this scenario and highlight common patterns and properties...

    Full Text Available This paper provides insights into productivity in dairy processing companies in Slovenia, Croatia and Serbia. The aim is to find out whether EBITDA per employee, as a measure of overall productivity as well as labour and capital productivity and their management positively affect company’s profitability. Literature review shows that this issue was relatively neglected, although increase in productivity is regarded as the most important factor in maintaining a competitive advantage in most developed countries. Results obtained show that comprehensive measure of productivity EBITDA per employee has statistically significant positive impact on company’s profitability, the same as productivity management components labour cost competitiveness and capital productivity.

    This study examines how familiarity with an issue—nanotechnology—moderates the effect of exposure to science information on how people process mediated messages about a complex issue. In an online experiment, we provide a nationally representative sample three definitions of nanotechnology (technical, technical applications, and technical risk/benefit definitions). We then ask them to read an article about the topic. We find significant interactions between perceived nano-familiarity and the definition received in terms of how respondents perceive favorable information conveyed in the stimulus. People less familiar with nanotechnology were more significantly affected by the type of definition they received.

  7. Experimental studies of parameters affecting the heat generation in friction stir welding process

    2012-01-01

    Full Text Available Heat generation is a complex process of transformation of a specific type of energy into heat. During friction stir welding, one part of mechanical energy delivered to the welding tool is consumed in the welding process, another is used for deformational processes etc., and the rest of the energy is transformed into heat. The analytical procedure for the estimation of heat generated during friction stir welding is very complex because it includes a significant number of variables and parameters, and many of them cannot be fully mathematically explained. Because of that, the analytical model for the estimation of heat generated during friction stir welding defines variables and parameters that dominantly affect heat generation. These parameters are numerous and some of them, e. g. loads, friction coefficient, torque, temperature, are estimated experimentally. Due to the complex geometry of the friction stir welding process and requirements of the measuring equipment, adequate measuring configurations and specific constructional solutions that provide adequate measuring positions are necessary. This paper gives an overview of the process of heat generation during friction stir welding, the most influencing parameters on heat generation, constructional solutions for the measuring equipment needed for these experimental researches and examples of measured values.

    Tomato sauce is the most commonly consumed processed tomato product worldwide, but very little is known about how the manufacturing process may affect the phenolic composition and bioavailability after consumption. In a prospective randomised, cross-over intervention study, we analysed the plasma and urinary levels of tomato phenolic compounds and their metabolites after acute consumption of raw tomatoes and tomato sauce, enriched or not with refined olive oil during production. Respectively, eleven and four phenolic metabolites were found in urine and plasma samples. The plasma concentration and urinary excretion of naringenin glucuronide were both significantly higher after the consumption of tomato sauce than raw tomatoes. The results suggest that the mechanical and thermal treatments during tomato sauce manufacture may help to deliver these potentially bioactive phenolics from the food matrix more effectively than the addition of an oil component, thus increasing their bioavailability.

    Freidin, Esteban; Carballo, Fabricio; Bentosela, Mariana

    2017-04-01

    The presence of direct reciprocity in animals is a debated topic, because, despite its evolutionary plausibility, it is believed to be uncommon. Some authors claim that stable reciprocal exchanges require sophisticated cognition which has acted as a constraint on its evolution across species. In contrast, a more recent trend of research has focused on the possibility that direct reciprocity occurs within long-term bonds and relies on simple as well as more complex affective mechanisms such as emotional book-keeping, rudimentary and higher forms of empathy, and inequity aversion, among others. First, we present evidence supporting the occurrence of long-term reciprocity in the context of existing bonds in social birds and mammals. Second, we discuss the evidence for affective responses which, modulated by bonding, may underlie altruistic behaviours in different species. We conclude that the mechanisms that may underlie reciprocal exchanges are diverse, and that some act in interaction with bonding processes. From simple associative learning in social contexts, through emotional contagion and behavioural mimicry, to empathy and a sense of fairness, widespread and diverse social affective mechanisms may explain why direct reciprocity may not be a rare phenomenon among social vertebrates. © 2015 International Union of Psychological Science.

    Di roma, Antonella; Vaccaro, Carmela

    2017-04-01

    The ground water should not be seen only as a reserve for the water supply, but also be protected for its environmental value. Groundwater plays an essential role in the hydrological cycle for which the characterization, pollution prevention, monitoring and restoration are essential in view of the recovery and identification of the water bodies to be submitted to recharge for the adaptation to DM n. 100/2016. Groundwater of Ferrara province presents salinisation problems and pollution of noxious metals that can be mitigated through recharge processes evaluated based on the specific site characteristics. It is essential to know the hydrogeochemical characteristics of different aquifer levels. To do this have been discuss analytical results of groundwater (2014-2015 monitoring phreatic ground water and temporal series from 2003-2015 A1-A2-A3 samples from Emilia Romagna databases). Results showed that in the territory analyzed insist both salinization and refreshening processes. Factor analysis(FA) conducted on samples has divided them into three groups. 1: samples affected by ionic exchange, 2: pH reaction on heavy metal, 3: samples affected by mineralization. The geochemical groundwater facies changed from Ca-HCO3, and NaHCO3 with a small samples group of CaSO4 and through geochemical investigations were observed the reactions that take place in the waters mixing of different composition. The Na excesses are explained by ionic exchange processes. A determinant role is played by ionic exchange between Ca and Na. In this territory is important also the role of CH4 presence which typically rises towards the surface along faults and fractures and influence rise of deep water with different composition. On samples selected from FA Group 1 has been observed an increase of the CEC (Cation exchange capacity). Adsorption-desorption exchanges take place between water and the fine fraction sediment rich in clay minerals. Higher CEC values are found in rich organic substance

    Prefrontal cortical executive functions comprise a number of cognitive capabilities necessary for goal directed behavior and adaptation to a changing environment. Executive dysfunction that leads to maladaptive behavior and is a symptom of psychiatric pathology can be instigated or exacerbated by stress. In this review we survey research addressing the impact of stress on executive function, with specific focus on working memory, attention, response inhibition, and cognitive flexibility. We then consider the neurochemical pathways underlying these cognitive capabilities and, where known, how stress alters them. Finally, we review work exploring potential pharmacological and non-pharmacological approaches that can ameliorate deficits in executive function. Both preclinical and clinical literature indicates that chronic stress negatively affects executive function. Although some of the circuitry and neurochemical processes underlying executive function have been characterized, a great deal is still unknown regarding how stress affects these processes. Additional work focusing on this question is needed in order to make progress on developing interventions that ameliorate executive dysfunction. Published by Elsevier Inc.

  15. Insecticide use in hybrid onion seed production affects pre- and postpollination processes.

    Science.gov (United States)

    Gillespie, Sandra; Long, Rachael; Seitz, Nicola; Williams, Neal

    2014-02-01

    Research on threats to pollination service in agro-ecosystems has focused primarily on the negative impacts of land use change and agricultural practices such as insecticide use on pollinator populations. Insecticide use could also affect the pollination process, through nonlethal impacts on pollinator attraction and postpollination processes such as pollen viability or pollen tube growth. Hybrid onion seed (Allium cepa L., Alliaceae) is an important pollinator-dependent crop that has suffered yield declines in California, concurrent with increased insecticide use. Field studies suggest that insecticide use reduces pollination service in this system. We conducted a field experiment manipulating insecticide use to examine the impacts of insecticides on 1) pollinator attraction, 2) pollen/stigma interactions, and 3) seed set and seed quality. Select insecticides had negative impacts on pollinator attraction and pollen/stigma interactions, with certain products dramatically reducing pollen germination and pollen tube growth. Decreased pollen germination was not associated with reduced seed set; however, reduced pollinator attraction was associated with lower seed set and seed quality, for one of the two female lines examined. Our results highlight the importance of pesticide effects on the pollination process. Overuse may lead to yield reductions through impacts on pollinator behavior and postpollination processes. Overall, in hybrid onion seed production, moderation in insecticide use is advised when controlling onion thrips, Thrips tabaci, on commercial fields.

  16. Narrative Aversion: Challenges for the Illness Narrative Advocate.

    Science.gov (United States)

    Behrendt, Kathy

    2017-02-01

    Engaging in self-narrative is often touted as a powerful antidote to the bad effects of illness. However, there are various examples of what may broadly be termed "aversion" to illness narrative. I group these into three kinds: aversion to certain types of illness narrative; aversion to illness narrative as a whole; and aversion to illness narrative as an essentially therapeutic endeavor. These aversions can throw into doubt the advantages claimed for the illness narrator, including the key benefits of repair to the damage illness does to identity and life-trajectory. Underlying these alleged benefits are two key presuppositions: that it is the whole of one's life that is narratively unified, and that one's identity is inextricably bound up with narrative. By letting go of these assumptions, illness narrative advocates can respond to the challenges of narrative aversions. © The Author 2016.

    Full Text Available The aim of this study is to investigate how applied theatre can facilitate arenas and methods to support identity development particularly favorable to an intercultural context, explored through the concept of narrative identity. Identity and identity processes may be extra challenging to people with intercultural backgrounds. Research shows that how you master your identity affects how you master your life. A case study of two intercultural applied theatre projects was used to address the research question. The article builds on the experiences of two drama teachers and one teaching artist / artistic leader. The interpretation and analysis of the theory related to practice makes visible how aesthetic processes of negotiating and staging life stories (narratives, through applied theatre methods, facilitate participant's exploring, constructing, re-constructing and meta-reflecting own identity.

    2018-06-01

    This article analyses the impact of narratives on entrepreneurial attitudes and intentions. To this end, a quasi-experiment was conducted to evaluate web-based entrepreneurial narratives. The paired-sample tests and regression analysis use a sample of 466 people from Austria, Finland, and Greece and indicate that individuals' perceptions of the desirability of entrepreneurship and entrepreneurial intention are significantly different before and after exposure to entrepreneurial narratives. Furthermore, the findings indicate that perceptions of the feasibility of entrepreneurship are more strongly affected by videos than by cases. From a policy perspective, this study raises awareness that entrepreneurship is an attractive career path.

  19. Factors Affecting Ballability of Mixture Iron Ore Concentrates and Iron Oxide Bearing Wastes in Metallurgical Processing

    2018-05-01

    Full Text Available Iron oxide bearing wastes (IROBEWAS are produced at every segment of processing stage of sinter, molten iron and steel production. They are hard to handle and in many cases are stockpiled only to be a source of environmental pollution but can be balled into pellets. Pellet of good ballability values are transportable and recyclable as they can withstand stress they will encounter without disintegrating back to dust. But ballability is affected by some factors like the grain sizes of the materials, the moisture and binder contents of the ball mix, wettability of the balled materials and the processing perimeters of the granulator. The objective of this research work is to investigate the factors affecting ballability of mixture of iron ore concentrates and iron oxide bearing wastes (IROBEWAS in metallurgical processing. The parameters under consideration were grain size of materials, the moisture contents, the speed of balling disc, IROBEWAS and Bentonite (Binder contents of the balled mix. This was carried out by balling different volume fractions of mix containing iron oxide concentrate and IROBEWAS using a balling disc and testing the resulting balls for green compressive strength using universal testing machine. It was found that the ballability of the mixture of iron ore concentrate and IROBEWAS increases as grain sizes of the materials reduce but increases as the moisture contents and IROBEWAS content increase up to an optimum value of moisture content in the mix before it starts to reduce. The ballability also increases as the speed of the granulator (Balling disc increases within the limit of this work. It was also observed that there was an increase in ballability with slight increase in bentonite content in the mix.

    2014-12-01

    Full Text Available This paper discusses the expressions used to refer to the experience of immersive in narrative games. The starting point is a review of the meanings associated with the suspension of disbelief in literature, cinema and television, challenging the myth of the naïve audience that cannot distinguish between representation and reality. Two characteristics of interactive media narratives – the possibility of agency and the disparities between hardware and software interfaces – reveal the active nature of the audience’s involvement with media representations. It is proposed that, in the case of games, this ability, which allows for simultaneous actions in the world of games and in the real world, is better described as a performance of belief.

    2017-12-01

    Tree breakage and uprooting are two possible scenarios of tree death that have differing effects on hillslope processes. In this study we aimed to (i) reveal the long-term structure of the biomechanical effects of trees (BETs) in relation to their radial growth and tree death types in four old-growth temperate forests in four different elevation settings with an altitudinal gradient of 152-1105 m a.s.l., (ii) quantify affected areas and soil volumes associated with the studied BETs in reserves, and (iii) derive a general model of the role of BETs in hillslope processes in central European temperate forests. We analyzed the individual dynamics of circa 55,000 trees in an area of 161 ha within four old-growth forests over 3-4 decades. Basal tree censuses established in all sites in the 1970s and repeated tree censuses in the 1990s and 2000s provided detailed information about the radial growth of each tree of DBH ≥ 10 cm as well as about types of tree death. We focused on the quantification of: (i) surviving still-living trees, (ii) new recruits, (iii) standing dead trees, (iv) uprooted trees, and (v) broken trees. Frequencies of phenomena were related to affected areas and volumes of soil using individual statistical models. The elevation contrasts were a significant factor in the structure of BETs. Differences between sites increased from frequencies of events through affected areas to volumes of soil associated with BETs. An average 2.7 m3 ha-1 year-1 was associated with all BETs of the living and dying trees in lowlands, while there was an average of 7.8 m3 ha-1 year-1 in the highest mountain site. Differences were caused mainly by the effects of dying trees. BETs associated with dead trees were 7-8 times larger in the mountains. Effects of dying trees and particularly treethrows represented about 70% of all BETs at both mountain sites, while it was 58% at the highland site and only 32% at the lowland site. Our results show a more significant role of BETs in

    Full Text Available Abstract With Highlighted presence of video m edia in society, its impact on other branches of art and poetry is seen more than before. At the beginning of being familiar with movie in Iran's traditional society, the subject was somehow a taboo and there was no trace of its influence on literature. Due to their poets' worldview, Nimaian poetry and subsequently blank verse reconciled with cinema earlier than classical poetry , but after Iran revolution and deep transformations resulting from war, Ghazal considered cinema and methods of narrative in cinema with a new look. This process is clearly evident in the lyric poets of the post- revolution.  Narrative  "In the simplest sense, narrative is a story that occurs during time and the narrator is one who narrates the story" (Khalil, 1383: p 107. Better expressed, "The story is what is said and narration is how to say it" (Afkhami, 1382: p 59. One of the main concerns of Nima is entering narrative element as an effective actor in poetry, but perhaps as intensely as contemporary poets of Ghazal have noticed to this Nima's advice, today his followers do not.   Narrative in Persian poetry   Narratives form a large part of Persian literature . Narrative poem dates back to the first versified epics . In Persian , narrative poetry is often versified in the form of couplet-poem and in two meter of Motaghareb and Hazaj as follows :   1 - " national epic narratives   2 - historical narratives   3 - love and public narratives   4 - allegorical or moral narratives "( Dad, 13 80: narrative poetry entry   Characteristics of narrative Ghazal   1- The first outcome of narrative Ghazal is the strength of its vertical axis . This artistically makes Ghazal a systematic and coherent structure in which verse or hemistich is no more a semantic unit , but all parts of poem carries the burden of meaning of the poem , so verses can no longer move or change .   2-Translatability is the other results of narrative

  8. Narrative means to manage responsibility in life narratives across adolescence.

    2011-01-01

    Adolescence is a passage from dependence to adult responsibility. Alongside identity development, social-cognitive development, and the ability to construct a life story, adolescents become increasingly aware of both their potential responsibility in an expanded sphere of life and of complex, contextual influences on their lives. This was partially tested in a cross-sectional study, both in terms of linguistic means and content expressed in life narratives. Indicators were defined for narrative agency, grading of responsibility, serendipity, and turning points, and tested for age differences in relative frequencies in 102 life narratives from age groups of 8, 12, 16, and 20 years, balanced for gender. Narrative grading of responsibility, serendipity, and turning points increased throughout adolescence. The relative frequency of narrative agency, in contrast, remained constant across age groups. Results are interpreted in the context of adolescent development of narrative identity.

    The extraction process used to obtain bitumen from the oil sands produces large volumes of oil sands process-affected water (OSPW). As a newly emerging desalination technology, forward osmosis (FO) has shown great promise in saving electrical power requirements, increasing water recovery, and minimizing brine discharge. With the support of this funding, a FO system was constructed using a cellulose triacetate FO membrane to test the feasibility of OSPW desalination and contaminant removal. The FO systems were optimized using different types and concentrations of draw solution. The FO system using 4 M NH4HCO3 as a draw solution achieved 85% water recovery from OSPW, and 80 to 100% contaminant rejection for most metals and ions. A water backwash cleaning method was applied to clean the fouled membrane, and the cleaned membrane achieved 77% water recovery, a performance comparable to that of new FO membranes. This suggests that the membrane fouling was reversible. The FO system developed in this project provides a novel and energy efficient strategy to remediate the tailings waters generated by oil sands bitumen extraction and processing.

    2011-04-01

    Full Text Available Recent studies suggested to approach to the analysis of the emotions and cognition from an integrating point of view rather than investigate the two constructs per se. In line with this research approach, the present study aims to investigate how emotions can affect memory processes and which cerebral areas are involved in this mechanism. We also aim to understand if and how this processing is influenced by specific personality traits, as anxiety trait. Using a rTMS measure, participants were asked to performance a memory task (a retrieval task composed by verbal material with and without emotional content. Subjects were also assessed for their anxiety trait (high and low anxiety subjects. Our study provided a strong evidence for the influence of the emotional content and personality trait on the memory processes. Secondly, the role of the Left Dorso-Lateral Prefrontal Cortex in emotional memory was pointed out with a specific function of this frontal network in managing the emotional memories.

  11. A plastome mutation affects processing of both chloroplast and nuclear DNA-encoded plastid proteins.

    Johnson, E M; Schnabelrauch, L S; Sears, B B

    1991-01-01

    Immunoblotting of a chloroplast mutant (pm7) of Oenothera showed that three proteins, cytochrome f and the 23 kDa and 16 kDa subunits of the oxygen-evolving subcomplex of photosystem II, were larger than the corresponding mature proteins of the wild type and, thus, appear to be improperly processed in pm7. The mutant is also chlorotic and has little or no internal membrane development in the plastids. The improperly processed proteins, and other proteins that are completely missing, represent products of both the plastid and nuclear genomes. To test for linkage of these defects, a green revertant of pm7 was isolated from cultures in which the mutant plastids were maintained in a nuclear background homozygous for the plastome mutator (pm) gene. In this revertant, all proteins analyzed co-reverted to the wild-type condition, indicating that a single mutation in a plastome gene is responsible for the complex phenotype of pm7. These results suggest that the defect in pm7 lies in a gene that affects a processing protease encoded in the chloroplast genome.

    2013-01-01

    Although rare species are often the focus of conservation measures, more common species may experience similar decline and suffer from the same threatening processes. We tested this hypothesis by examining, through an information-theoretic approach, the importance of ecological processes at multiple scales in the great crested newt Triturus cristatus, regionally endangered and protected in Europe, and the more common smooth newt, Lissotriton vulgaris. Both species were similarly affected by the same processes, i.e. suitability of aquatic and terrestrial components of their habitat at different scales, connectivity among breeding sites, and the presence of introduced fish. T. cristatus depended more on water depth and aquatic vegetation than L. vulgaris. The results show that environmental pressures threaten both common and rare species, and therefore the more widespread species should not be neglected in conservation programs. Because environmental trends are leading to a deterioration of aquatic and terrestrial habitat features required by newt populations, populations of the common species may follow the fate of the rarest species. This could have substantial conservation implications because of the numerical importance of common species in ecosystems and because commonness could be a transient state moving towards rarity. On the other hand, in agreement with the umbrella species concept, targeting conservation efforts on the most demanding species would also protect part of the populations of the most common species.

    Although negative affect is associated with a number of smoking-related cognitive processes, the mechanisms underlying these associations have yet to be examined. The current study sought to examine the indirect effect of emotion regulation difficulties in terms of the association between negative affect and smoking-related cognitive processes (internal barriers to cessation, negative affect reduction smoking motives, negative affect reduction smoking outcome expectancies). Participants were 126 daily cigarette smokers (70.4% male, Mage=36.5years, SD=13.0; 69.8% Caucasian) who smoked an average of 18.5 (SD=8.7) cigarettes per day and reported moderate nicotine dependence. Formal mediation analyses were conducted using PROCESS to examine the indirect effect of negative affect on internal barriers to cessation and negative affect reduction smoking motives and outcome expectancies through emotion regulation difficulties. After accounting for the effects of gender, daily smoking rate, and anxiety sensitivity, negative affect was indirectly related to internal barriers to cessation and negative affect reduction smoking motives through emotion regulation difficulties. There was no significant indirect effect for negative affect reduction smoking outcome expectancies. These findings suggest that greater negative affect is associated with a desire to smoke to reduce this negative affect and perceptions that quitting smoking will be difficult due to negative emotions because of greater difficulties managing these negative emotions. Thus, emotion regulation difficulties may be an important target for smoking cessation interventions. Copyright © 2015 Elsevier Ltd. All rights reserved.

    The reader might get the impression that the four projects described in this Special Section proceeded in a systematic and predictable way. Of course, those of us engaged in each research project encountered pitfalls and challenges along the way. A main goal of this Special Section is to provide pathways and encouragement for those who may be interested in advancing high-quality research on this topic. In this paper, we describe a set of practical and ethical challenges that we encountered in conducting our longitudinal, process-oriented, and translational research with conflict-affected youth, and we illustrate how problems can be solved with the goal of maintaining the internal and external validity of the research designs. We are hopeful that by describing the challenges of our work, and how we overcame them, which are seldom treated in this or any other literature on research on child development in high-risk contexts, we can offer a realistic and encouraging picture of conducting methodologically sound research in conflict-affected contexts.

    Ubiquitination is the most versatile posttranslational modification. The information is encoded by linkage type as well as chain length, which are translated by ubiquitin binding domains into specific signaling events. Chain topology determines the conformational space of a ubiquitin chain and adds an additional regulatory layer to this ubiquitin code. In particular, processes that modify chain length will be affected by chain conformations as they require access to the elongation or cleavage sites. We investigated conformational distributions in the context of chain elongation and disassembly using pulsed electron-electron double resonance spectroscopy in combination with molecular modeling. Analysis of the conformational space of diubiquitin revealed conformational selection or remodeling as mechanisms for chain recognition during elongation or hydrolysis, respectively. Chain elongation to tetraubiquitin increases the sampled conformational space, suggesting that a high intrinsic flexibility of K48-linked chains may contribute to efficient proteasomal degradation.

    Full Text Available From 2000 to 2003 we quantified drain flow, drain-and ground-water chemistry and hydrogeologic conditions on Twitchell Island in the Sacramento-San Joaquin Delta. The primary objective was to quantify processes affecting organic carbon concentrations and loads in agricultural drainage water. We collected physical and chemical data in southern and northern areas: TN and TS, respectively. Corn grew in both areas during the spring and summer. The peat soils in the TN area are more decomposed than those in the TS area. Results elucidate processes affecting drain flow and concentrations under varying hydrologic conditions. During May through November, groundwater flows from the permanently saturated zone to drainage ditches, and the resulting average drainage-water quality and dissolved organic carbon (DOC concentration was similar to the groundwater; the median DOC loads in the TN and TS study areas ranged from 9 to 27 g C/ha-day. The major ion chemistry and stable isotope data confirmed that groundwater was the primary source of drainflow. In contrast, during December through April the drainwater is supplied from the shallow, variably saturated soil-zone. The DOC concentrations, major-ion chemistry, and stable isotope data indicate that the shallow-zone water is partially evaporated and oxidized. Higher flows and DOC concentrations during these months result in higher median DOC loads, which ranged from 84 to 280 g C/ha-day. During December through April, increasing groundwater levels in the shallow peat layers and mobilization of organic carbon result in high drain flow and increased trihalomethane precursor concentrations and loads. On a per mass DOC basis, drain water collected during high flow periods is less likely to form THMs than during low flow periods. However, the high flows and subsequent high concentrations contribute to substantially higher trihalomethane precursor and DOC loads.

    To identify and prioritize factors affecting the location of road emergency bases in Iran using Analytical Hierarchy Process (AHP). This was a mixed method (quantitative-qualitative) study conducted in 2016. The participants in this study included the professionals and experts in the field of pre-hospital and road emergency services issues working in the Health Deputy of Iran Ministry of Health and Medical Education, which were selected using purposive sampling method. In this study at first, the factors affecting the location of road emergency bases in Iran were identified using literature review and conducting interviews with the experts. Then, the identified factors were scored and prioritized using the studied professionals and experts' viewpoints through using the analytic hierarchy process (AHP) technique and its related pair-wise questionnaire. The collected data were analyzed using MAXQDA 10.0 software to analyze the answers given to the open question and Expert Choice 10.0 software to determine the weights and priorities of the identified factors. The results showed that eight factors were effective in locating the road emergency bases in Iran from the viewpoints of the studied professionals and experts in the field of pre-hospital and road emergency services issues, including respectively distance from the next base, region population, topography and geographical situation of the region, the volume of road traffic, the existence of amenities such as water, electricity, gas, etc. and proximity to the village, accident-prone sites, University ownership of the base site, and proximity to toll-house. Among the eight factors which were effective in locating the road emergency bases from the studied professionals and experts' perspectives, "distance from the next base" and "region population" were respectively the most important ones which had great differences with other factors.

  1. Faces in context: A review and systematization of contextual influences on affective face processing

    Directory of Open Access Journals (Sweden)

    Matthias J Wieser

    2012-11-01

    Full Text Available Facial expressions are of eminent importance for social interaction as they convey information about other individuals’ emotions and social intentions. According to the predominant basic emotion approach, the perception of emotion in faces is based on the rapid, automatic categorization of prototypical, universal expressions. Consequently, the perception of facial expressions has typically been investigated using isolated, decontextualized, static pictures of facial expressions that maximize the distinction between categories. However, in everyday life, an individual’s face is not perceived in isolation, but almost always appears within a situational context, which may arise from other people, the physical environment surrounding the face, as well as multichannel information from the sender. Furthermore, situational context may be provided by the perceiver, including already present social information gained from affective learning and implicit processing biases such as race bias. Thus, the perception of facial expressions is presumably always influenced by contextual variables. In this comprehensive review, we aim at 1 systematizing the contextual variables that may influence the perception of facial expressions and 2 summarizing experimental paradigms and findings that have been used to investigate these influences. The studies reviewed here demonstrate that perception and neural processing of facial expressions are substantially modified by contextual information, including verbal, visual, and auditory information presented together with the face as well as knowledge or processing biases already present in the observer. These findings further challenge the assumption of automatic, hardwired categorical emotion extraction mechanisms predicted by basic emotion theories. Taking into account a recent model on face processing, we discuss where and when these different contextual influences may take place, thus outlining potential avenues in

  2. Early affective processing in patients with acute posttraumatic stress disorder: magnetoencephalographic correlates.

    Directory of Open Access Journals (Sweden)

    Markus Burgmer

    Full Text Available In chronic PTSD, a preattentive neural alarm system responds rapidly to emotional information, leading to increased prefrontal cortex (PFC activation at early processing stages (<100 ms. Enhanced PFC responses are followed by a reduction in occipito-temporal activity during later processing stages. However, it remains unknown if this neuronal pattern is a result of a long lasting mental disorder or if it represents changes in brain function as direct consequences of severe trauma.The present study investigates early fear network activity in acutely traumatized patients with PTSD. It focuses on the question whether dysfunctions previously observed in chronic PTSD patients are already present shortly after trauma exposure. We recorded neuromagnetic activity towards emotional pictures in seven acutely traumatized PTSD patients between one and seven weeks after trauma exposure and compared brain responses to a balanced healthy control sample. Inverse modelling served for mapping sources of differential activation in the brain.Compared to the control group, acutely traumatized PTSD patients showed an enhanced PFC response to high-arousing pictures between 60 to 80 ms. This rapid prefrontal hypervigilance towards arousing pictorial stimuli was sustained during 120-300 ms, where it was accompanied by a reduced affective modulation of occipito-temporal neural processing.Our findings indicate that the hypervigilance-avoidance pattern seen in chronic PTSD is not necessarily a product of an endured mental disorder, but arises as an almost immediate result of severe traumatisation. Thus, traumatic experiences can influence emotion processing strongly, leading to long-lasting changes in trauma network activation and expediting a chronic manifestation of maladaptive cognitive and behavioral symptoms.

    Narratives, also called stories, can be found in conversations, children's play interactions, reading material, and television programs. From infancy to adulthood, narrative comprehension processes interpret events and inform our understanding of physical and social environments. These processes have been extensively studied to ascertain the multifaceted nature of narrative comprehension. From this research we know that three overlapping processes (i.e., knowledge integration, goal structure understanding, and causal inference generation) proposed by the constructionist paradigm are necessary for narrative comprehension, narrative comprehension has a predictive relationship with children's later reading performance, and comprehension processes are generalizable to other contexts. Much of the previous research has emphasized internal and predictive validity; thus, limiting the generalizability of previous findings. We are concerned these limitations may be excluding underrepresented populations from benefits and implications identified by early comprehension processes research. This review identifies gaps in extant literature regarding external validity and argues for increased emphasis on externally valid research. We highlight limited research on narrative comprehension processes in children from low-income and minority populations, and argue for changes in comprehension assessments. Specifically, we argue both on- and off-line assessments should be used across various narrative types (e.g., picture books, televised narratives) with traditionally underserved and underrepresented populations. We propose increasing the generalizability of narrative comprehension processes research can inform persistent reading achievement gaps, and have practical implications for how children learn from narratives.

    Per Krogh Hansen brings attention to one of the most discussed narratological concepts in recent years, the ‘unreliable narrator’. In the article »The Dynamics of Unreliable Narration«, Hansen is considering to what extent the question of authorial control or intention is relevant when analysing...... and interpreting unreliable narrators. In the first part of the article, he questions this claimed essentiality of an authorial agent from three different angles: One concerning the border between diegetic and extradiegetic issues. Another with specific focus on unreliable simultaneous narration (first person......, present tense). And a third with attention paid to the role of unreliable narrators in factual narratives. In the article, he proposes a model for describing the different dynamic roles the authorial agent, as well as the empirical reader, plays in different forms of unreliable narration. Here, terms like...

    2015-10-01

    We sought to learn how employees reacted to changes in the corporate narrative of Philip Morris Companies (PMC) in the late 1990s and early 2000s. We analyzed archival internal tobacco industry documents about PMC's creation of a new corporate story. In response to litigation and public opprobrium, PMC replaced its market success-oriented corporate narrative with a new one centered on responsibility. Although management sought to downplay inconsistencies between the old and new narratives, some employees reportedly had difficulty reconciling them, concerned that the responsibility focus might affect company profitability. However, others embraced the new narrative, suggesting radical ideas to prevent youth smoking. These ideas were not adopted. PMC's new narrative was unconvincing to many of its employees, who perceived it either as a threat to the company's continued profits or as incongruous with what they had previously been told. As it had done with the public, PMC misled its employees in explaining a narrative repositioning that would help the company continue business as usual. Moving toward a tobacco endgame will require ongoing discursive and symbolic efforts to disrupt this narrative.

    Epigenetics, which is just beginning to attract public attention and policy discussion, challenges conventional understanding of gene-environment interaction and intergenerational inheritance and perhaps much more besides. Does epigenetics challenge modern political ideologies? I analyzed the narratives of obesity and epigenetics recently published in the more liberal New York Times and the more conservative Wall Street Journal. For the years 2010 through 2014, 50 articles on obesity and 29 articles on epigenetics were identified, and elements in their causal narratives were quantitatively analyzed using a well described narrative policy framework. The narratives on obesity aligned with the two newspapers' reputed ideologies. However, the narratives on epigenetics aligned with neither ideology but freely mixed liberal and conservative elements. This small study may serve as a starting point for broader studies of epigenetics as it comes to affect political ideologies and, in turn, public policies. The narrative mix reported here could yet prove vulnerable to ideological capture, or, more optimistically, could portend the emergence of a "third-way" narrative using epigenetics to question atomistic individualism and allowing for less divisiveness in public-health domains such as obesity.

    Several measures have been recommended to guarantee a sustainable population of tigers: sufficient inviolate spaces for a viable population, sufficient prey populations, trained and skilled manpower to guard against poaching and intrusion, banning trade in tiger products to reduce poaching, and importantly, the political will to precipitate these recommendations into implementation. Of these, the creation of sufficient inviolate spaces (generally in the form of protected areas) has created the most issues with local resource-dependent communities, often resulting in significant challenges for tiger conservation policy and management. Very little empirical research has, however, been done to understand and contextualize the local-level socio-political interactions that may influence the efficacy of tiger conservation in India. In this paper, we present the results of exploratory research into the ways in which local-stakeholder groups affect the management of Corbett Tiger Reserve (CTR). Using a combined grounded theory-case study research design, and the Institutional Analysis and Development framework for analysis, we identify the socio-political processes through which local-stakeholder groups are able to articulate their issues and elicit desirable actions from the management of CTR. Increasing our awareness of these processes can help inform the design and implementation of more effective tiger conservation management and policy strategies that have the potential to create more supportive coalitions of tiger conservation stakeholders at the local level.

  11. Carbon availability affects diurnally controlled processes and cell morphology of Cyanothece 51142.

    Jana Stöckel

    Full Text Available Cyanobacteria are oxygenic photoautotrophs notable for their ability to utilize atmospheric CO2 as the major source of carbon. The prospect of using cyanobacteria to convert solar energy and high concentrations of CO2 efficiently into biomass and renewable energy sources has sparked substantial interest in using flue gas from coal-burning power plants as a source of inorganic carbon. However, in order to guide further advances in this area, a better understanding of the metabolic changes that occur under conditions of high CO2 is needed. To determine the effect of high CO2 on cell physiology and growth, we analyzed the global transcriptional changes in the unicellular diazotrophic cyanobacterium Cyanothece 51142 grown in 8% CO2-enriched air. We found a concerted response of genes related to photosynthesis, carbon metabolism, respiration, nitrogen fixation, ribosome biosynthesis, and the synthesis of nucleotides and structural cell wall polysaccharides. The overall response to 8% CO2 in Cyanothece 51142 involves different strategies, to compensate for the high C/N ratio during both phases of the diurnal cycle. Our analyses show that high CO2 conditions trigger the production of carbon-rich compounds and stimulate processes such as respiration and nitrogen fixation. In addition, we observed that high levels of CO2 affect fundamental cellular processes such as cell growth and dramatically alter the intracellular morphology. This study provides novel insights on how diurnal and developmental rhythms are integrated to facilitate adaptation to high CO2 in Cyanothece 51142.

    Full Text Available Interference control and conflict resolution is affected by ageing. There is increasing evidence that ageing does not compromise interference control in general but rather shows distinctive effects on different components of interference control. Different conflict types, (e.g. stimulus-stimulus (S-S or stimulus-response (S-R conflicts trigger different cognitive processes and thus activate different neural networks. In the present functional magnetic resonance imaging (fMRI study, we used a combined Flanker and Stimulus Response Conflict (SRC task to investigate the effect of ageing on S-S and S-R conflicts. Behavioral data analysis revealed larger SRC effects in elderly. fMRI Results show that both age groups recruited similar regions (caudate nucleus, cingulate gyrus and middle occipital gyrus during Flanker conflict processing. Furthermore, elderly show an additional activation pattern in parietal and frontal areas. In contrast, no common activation of both age groups was found in response to the SRC. These data suggest that ageing has distinctive effects on S-S and S-R conflicts.

    Functional imaging of normal and dysfunctional emotional processes is an important tool for a better understanding of the pathophysiology of affective symptoms in schizophrenia patients. These symptoms are still poorly characterized with respect to their neural correlates. Comparisons of cerebral activation during emotional paradigms offered the possibility for a better characterization of cerebral dysfunctions during emotional processing in schizophrenia. Abnormal activation patterns reveal a complex dysfunctional subcortical-cortical network. This is modulated by respective genotypes as well as psycho- and pharmacotherapy. (orig.) [German] Die funktionell bildgebende Untersuchung emotionaler Prozesse und ihrer Dysfunktionen ist fuer ein besseres Verstaendnis der Pathophysiologie emotionaler Stoerungen wesentlich. Schizophrene Patienten zeigen eine Reihe affektiver Symptome, die klinisch relevant, aber nur unzureichend bzgl. ihrer neurobiologischen Korrelate bekannt sind. Der Vergleich zerebraler Aktivierung zwischen gesunden und schizophrenen Patienten waehrend unterschiedlicher emotionaler Paradigmen hat dazu beigetragen, zerebrale Dysfunktionen naeher zu charakterisieren. So weisen auffaellige Aktivierungsmuster auf eine komplex gestoerte subkortikal-kortikale Netzwerkstruktur hin. Deren Modulation durch genetische Faktoren und durch psycho- wie auch pharmakologische therapeutische Interventionen konnte mittlerweile nachgewiesen werden. (orig.)

    Full Text Available The factors that affect honey quality in Uganda were surveyed in 120 beekeeping households. Honey was sampled from supermarkets, hawkers and stall markets along four transects across Kampala, the capital. Honey quality parameters assessed were diastase number (DN, free acidity (FA, moisture content (MC, hydroxymethylfurfural (HMF, and water insoluble solids (WIS. Honey was mostly harvested from basket and grass hives. Pressing, boiling and straining were popular honey processing methods. Honey quality was mainly compromised by harvesting immature honey, bad extraction methods and contamination by extraneous materials.

  17. Narrative self-constitution and vulnerability to co-authoring.

    2016-02-01

    All people are vulnerable to having their self-concepts shaped by others. This article investigates that vulnerability using a theory of narrative self-constitution. According to narrative self-constitution, people depend on others to develop and maintain skills of self-narration and they are vulnerable to having the content of their self-narratives co-authored by others. This theoretical framework highlights how vulnerability to co-authoring is essential to developing a self-narrative and, thus, the possibility of autonomy. However, this vulnerability equally entails that co-authors can undermine autonomy by contributing disvalued content to the agent's self-narrative and undermining her authorial skills. I illustrate these processes with the first-hand reports of several women who survived sexual abuse as children. Their narratives of survival and healing reveal the challenges involved in (re)developing the skills required to manage vulnerability to co-authoring and how others can help in this process. Finally, I discuss some of the implications of co-authoring for the healthcare professional and the therapeutic relationship.

    2016-08-01

    Full Text Available This paper looks see how meaning is constructed in translated news texts about health and science and awards a narrative potential to unforced translation shifts, moving along the theoretical lines of Baker's Narrative Theory (2006. The thematic thread of health zooms in on “emotional frames” (Nabi, 2003 of risk and fear of human health that is narrated as being 'under attack’ by potentially dangerous diseases. Themes also orbit around schemas that promote hope and optimism about science represented as coming to the rescue of man from fear of the disease. The data consists of 21 pairs of English-Greek health news articles culled from the Greek newspapers I Kathimerini, To Vima and Ta Nea. Findings point towards translation as a process that employs lexicogrammatical and intrasentential configurations to a give emphasis to the risk or hope dimensions underlying a heath or science story, b enable the reflection or emergence of a cascade of public, conceptual and master narratives.

    2013-12-01

    Full Text Available Through the articulation of psychoanalysis and narrative analysis this study explores the processes of identification of children audiences with their favorite cartoon television programs. In order to understand the characteristics of identification processes, this study explores the way in which both the structure of cartoons and the affective histories of children influence children’s identification with their favorite television characters. To achieve that understanding we a analyzed the narrative elements of the television programs, b explored the children’s affective history, and c examined how these narrative elements and affective histories influence the appropriation of television programs. These three scenarios were examined through case study on four Colombian children between 6 to 10 years old. The analysis showed that affective factors of children’s personal history constitute a significant source of mediation on the appropriation of cartoons. In addition, the narrative elements of the programs become an essential motivation on children’s fantasies.

    This study investigated factors that may contribute to the presence of arsenic and other heavy metals in apple and grape juices processed with filter aids. Different types and grades of filter aids were analyzed for arsenic, lead, and cadmium with inductively coupled plasma-tandem mass spectrometry. Potential factors affecting the transfer of heavy metals to juices during filtration treatments were evaluated. Effects of washing treatments on removal of heavy metals from filter aids were also determined. Results showed that diatomaceous earth (DE) generally contained a higher level of arsenic than perlite, whereas perlite had a higher lead content than DE. Cellulose contained the lowest level of arsenic among the surveyed filter aids. All samples of food-grade filter aids contained arsenic and lead levels that were below the U.S. Pharmacopeia and National Formulary limits of 10 ppm of total leachable arsenic and lead for food-grade DE filter aids. Two samples of arsenic-rich (>3 ppm) food-grade filter aids raised the level of arsenic in apple and grape juices during laboratory-scale filtration treatments, whereas three samples of low-arsenic (filter aids did not affect arsenic levels in filtered juices. Filtration tests with simulated juices (pH 2.9 to 4.1, Brix [°Bx] 8.2 to 18.1, total suspended solids [TSS] 0.1 to 0.5%) showed that pH or sugar content had no effect on arsenic levels of filtered juices, whereas arsenic content of filtered juice was elevated when higher amounts of filter aid were used for filtration. Authentic unfiltered apple juice (pH 3.6, °Bx 12.9, TSS 0.4%) and grape juice (pH 3.3, °Bx 16.2, TSS 0.05%) were used to verify results obtained with simulated juices. However, body feed ratio did not affect the arsenic content of filtered authentic juices. Washing treatments were effective at reducing arsenic, but not cadmium or lead, concentrations in a DE filter aid. This study identified ways to reduce the amount of arsenic transferred to juices

    Full Text Available The purpose of the present study was to compare the effects of two different teaching methods on students' comprehension during Physical Education lesson: narration versus animation with concurrent narration, during teaching shot put event. Thirty primary school children (boys and girls volunteered to participate in this study. In experiment students listened (narration and viewed (animation with narration the presentation of two shot putting styles. A problem-solving and a retention test were used to evaluate students' comprehension. Results showed that students' comprehension was better when shot putting styles were presented through a mixed model (animation and narration group than a single (narration. The animation with concurrent narration group performed better than the narration group, in problem-solving (M = 4.91, SD = 1.36 and in retention test (M = 5.98, SD = 1.28 t(28 = 1.89 p<0.01. An instructional implication is that pictures with words is more effective way of teaching when they occur continuingly in time, than only words during Physical Education lesson.

    Full Text Available Advertising design is a discursive planning that does not only build an identity as brand value or graphic development, but also as Semiotics suggests, it produces a narrative level outlining the advertising story. The use of media, construction of characters, storytelling, organization of advertisement, are all expressions of this narrative level which in turn depends on a “context” or expression process from which they are built. This article aims to identify the different forms of narrative production in relation to three types of advertising discourse (Discourse Phase 1, Phase 2 and hyperadvertising as well as evaluate its contrasts and expressions within the advertising communication and consumer society.

    Elevated concentrations of arsenic (As) in shallow groundwater in Tulare Basin pose an environmental risk because of the carcinogenic properties of As and the potential for its migration to deep aquifers that could serve as a future drinking water source. Adsorption and desorption are hypothesized to be the major processes controlling As solubility in oxidized surface sediments where arsenate [As(V)] is dominant. This study examined the relationship between sorption processes and arsenic solubility in shallow sediments from the dry Tulare Lake bed by determining sorption isotherms, pH effect on solubility, and desorption-readsorption behavior (hysteresis), and by using a surface complexation model to describe sorption. The sediments showed a high capacity to adsorb As(V). Estimates of the maximum adsorption capacity were 92 mg As kg- 1 at pH 7.5 and 70 mg As kg- 1 at pH 8.5 obtained using the Langmuir adsorption isotherm. Soluble arsenic [> 97% As(V)] did not increase dramatically until above pH 10. In the native pH range (7.5-8.5), soluble As concentrations were close to the lowest, indicating that As was strongly retained on the sediment. A surface complexation model, the constant capacitance model, was able to provide a simultaneous fit to both adsorption isotherms (pH 7.5 and 8.5) and the adsorption envelope (pH effect on soluble As), although the data ranges are one order of magnitude different. A hysteresis phenomenon between As adsorbed on the sediment and As in solution phase was observed in the desorption-readsorption processes and differs from conventional hysteresis observed in adsorption-desorption processes. The cause is most likely due to modification of adsorbent surfaces in sediment samples upon extensive extractions (or desorption). The significance of the hysteresis phenomenon in affecting As solubility and mobility may be better understood by further microscopic studies of As interaction mechanisms with sediments subjected to extensive leaching

  9. Dangerous narratives: politics, lies, and ghost stories

    Full Text Available Narratives that resonate in the cultural imagination inform the ways in which we apprehend the world. This paper considers how certain images and stories that have been valorised over time, bleed into reality and become socially and politically affective. The identity of an entire people, for example, can be rendered down so that those social groups come to seem more spectral than human, through either misrecognition or a lack of acknowledgment. This idea will be discussed through two examples: one provided by traditional anti-Semitism, in which the Jew is viewed as a vampiristic agent of decay; and another in which the Arab presence becomes ‘spectralised’ in contemporary Israel/Palestine. We will look at the development of narratives that create these images, and also consider the liminal zone wherein those images have their source, because it is through imagination and storytelling that we continually create and recreate the realities we must then inhabit.

    Several factors were studied as affecting protein degradation and texture of skipjack tuna muscle following ambient pressure thermal processing (precooking). These included degree of mushy tuna syndrome (MTS) evidenced in the raw meat, raw meat pH, abusive thawing/holding, and precooking temperature/time. Slurries and intact pieces from frozen skipjack tuna, either tempered for 2 h or thawed and held at 25 °C for 22 h (abusive treatment) were heated at temperatures ranging from 40 to 80 °C for up to 2 h, and also at 90 °C for 1 h, with or without prior adjustment of pH to 5 or 7 to favor cathepsin or calpain activity, respectively. Proteolysis of precooked samples was monitored by Lowry assay and SDS-PAGE; cooked texture of intact meat was measured using a Kramer shear press and by sensory profile analysis. Proteolysis maximally occurred in slurries of skipjack tuna muscle that had been abusively stored (22 h at 25 °C) and adjusted to pH 5 prior to heating at 55 °C. Intact pieces of tuna abusively thawed/held for 22 h with subsequent heating at 55 °C also evidenced the most proteolysis and were the least firm in texture. Raw fish that evidenced higher severity of MTS when raw displayed higher levels of proteolysis prior to cooking, which were further increased after cooking at 55 °C. The kinetic data presented here can be used to optimize processing conditions for skipjack tuna canning to minimize textural degradation and optimize quality. © 2012 Institute of Food Technologists®

    The investigation of callous-unemotional (CU) traits has been central to contemporary research on child behavior problems, and served as the impetus for inclusion of a specifier for conduct disorder in the latest edition of the official psychiatric diagnostic system. Here, we report results from 2 studies that evaluated the construct validity of callousness as assessed in adults, by testing for affiliated deficits in behavioral and neural processing of fearful faces, as have been shown in youthful samples. We hypothesized that scores on an established measure of callousness would predict reduced recognition accuracy and diminished electocortical reactivity for fearful faces in adult participants. In Study 1, 66 undergraduate participants performed an emotion recognition task in which they viewed affective faces of different types and indicated the emotion expressed by each. In Study 2, electrocortical data were collected from 254 adult twins during viewing of fearful and neutral face stimuli, and scored for event-related response components. Analyses of Study 1 data revealed that higher callousness was associated with decreased recognition accuracy for fearful faces specifically. In Study 2, callousness was associated with reduced amplitude of both N170 and P200 responses to fearful faces. Current findings demonstrate for the first time that callousness in adults is associated with both behavioral and physiological deficits in the processing of fearful faces. These findings support the validity of the CU construct with adults and highlight the possibility of a multidomain measurement framework for continued study of this important clinical construct.

    The study brings together three aspects rarely observed at once in assistive technology (AT) surveys: (i) the assessment of user interaction/satisfaction with AT and service delivery, (ii) the motivational analysis of AT abandonment, and (iii) the management/design evaluation of AT delivery services. 15 health professionals and 4 AT experts were involved in modelling and assessing four AT Local Health Delivery Service (Centres) in Italy through a SWOT analysis and a Cognitive Walkthrough. In addition 558 users of the same Centres were interviewed in a telephone survey to rate their satisfaction and AT use. The overall AT abandonment was equal to 19.09%. Different Centres' management strategies resulted in different percentages of AT disuse, with a range from 12.61% to 24.26%. A significant difference between the declared abandonment and the Centres' management strategies (p = 0.012) was identified. A strong effect on abandonment was also found due to professionals' procedures (p = 0.005) and follow-up systems (p = 0.002). The user experience of an AT is affected not only by the quality of the interaction with the AT, but also by the perceived quality of the Centres in support and follow-up. Implications for Rehabilitation AT abandonment surveys provide useful information for modelling AT assessment and delivery process. SWOT and Cognitive Walkthrough analyses have shown suitable methods for exploring limits and advantages in AT service delivery systems. The study confirms the relevance of person centredness for a successful AT assessment and delivery process.

    Throughout the world, soil erosion by water is a serious problem, especially in semi-arid and semi-humid areas (Cerdà et al., 2009; Cerdan et al., 2010; García-Ruiz, 2010). Although soil erosion by water consists of physical processes that vary significantly in severity and frequency according to when and where they occur, they are also strongly influenced by anthropic factors such as land-use changes on large scales and unsustainable farming practices (Boardman et al., 1990; Cerdà 1994; Montgomery, 2007). Tillage operations, combined with weather conditions, are recognized to primarily influence soil erosion rates. If, on one hand, tillage operations cause uniform changes based on the tool used, on the other, weather conditions, such as rainfalls, produce more random changes, less easily traceable (Snapir et al., 2014). Within this context, remote-sensing technologies can facilitate the detection and quantification of these topographic changes. In particular, a real opportunity and challenge is offered by the low-cost and flexible photogrammetric technique, called 'Structure-from-Motion' (SfM), combined with the use of smartphones (Micheletti et al., 2014; Prosdocimi et al., 2015). This represents a significant advance compared with more expensive technologies and applications (e.g. Terrestrial Laser Scanner - TLS) (Tarolli, 2014). This work wants to test the Structure from Motion to obtain high-resolution topography for the detection of topographic changes in agricultural lands affected by erosion processes. Two case studies were selected: i) a tilled plot characterized by bare soil and affected by rill erosion located in the hilly countryside of Marche region (central Italy), and ii) a Mediterranean vineyard located within the province of Valencia (south eastern Spain) where rainfall simulation experiments were carried out. Extensive photosets were obtained by using one standalone reflex digital camera and one smartphone built-in digital camera. Digital

    The role of drug-paired environmental stimuli in opiate self-administration was investigated by exposing animals to discrete cues that were predictive of the availability or unavailability of heroin reinforcement. Rats were trained to traverse a straight arm runway for a reinforcement consisting of a single 0.1 mg/kg intravenous infusion of heroin delivered upon entrance to the goal box. On each trial, one of two discriminative olfactory stimuli (orange and almond) was used: one which signaled the availability of heroin in the goal box (S+), and one which signaled its absence (S-). The effect of dopamine (DA) receptor antagonism on reinforcement and motivational processes was investigated by pretreating subjects with 0.0, 0.15 or 0.30 mg/kg of the DA receptor antagonist drug, haloperidol. Haloperidol had no effect on operant runway performance (i.e. goal time) in any condition. However, 24 h later, on the first post-treatment trial, those haloperidol animals that received heroin in the goal box on the previous trial (i.e. the S+ condition) ran reliably more slowly than subjects that received vehicle on the previous S+ trial. These results suggest that haloperidol does not affect the motivational properties of stimuli which predict the availability of heroin, while it does diminish the reinforcing effects of actually receiving heroin.

    In daily life, speech perception is usually accompanied by other tasks that tap into working memory capacity. However, the role of working memory on speech processing is not clear. The goal of this study was to examine how working memory load affects the timeline for spoken word recognition in ideal listening conditions. We used the “visual world” eye-tracking paradigm. The task consisted of spoken instructions referring to one of four objects depicted on a computer monitor (e.g., “point at the candle”). Half of the trials presented a phonological competitor to the target word that either overlapped in the initial syllable (onset) or at the last syllable (offset). Eye movements captured listeners' ability to differentiate the target noun from its depicted phonological competitor (e.g., candy or sandal). We manipulated working memory load by using a digit pre-load task, where participants had to retain either one (low-load) or four (high-load) spoken digits for the duration of a spoken word recognition trial. The data show that the high-load condition delayed real-time target discrimination. Specifically, a four-digit load was sufficient to delay the point of discrimination between the spoken target word and its phonological competitor. Our results emphasize the important role working memory plays in speech perception, even when performed by young adults in ideal listening conditions. PMID:27242424

  16. The Electrochemical Properties of Biochars and How They Affect Soil Redox Properties and Processes

    Directory of Open Access Journals (Sweden)

    Stephen Joseph

    2015-07-01

    Full Text Available Biochars are complex heterogeneous materials that consist of mineral phases, amorphous C, graphitic C, and labile organic molecules, many of which can be either electron donors or acceptors when placed in soil. Biochar is a reductant, but its electrical and electrochemical properties are a function of both the temperature of production and the concentration and composition of the various redox active mineral and organic phases present. When biochars are added to soils, they interact with plant roots and root hairs, micro-organisms, soil organic matter, proteins and the nutrient-rich water to form complex organo-mineral-biochar complexes Redox reactions can play an important role in the development of these complexes, and can also result in significant changes in the original C matrix. This paper reviews the redox processes that take place in soil and how they may be affected by the addition of biochar. It reviews the available literature on the redox properties of different biochars. It also reviews how biochar redox properties have been measured and presents new methods and data for determining redox properties of fresh biochars and for biochar/soil systems.

    Behavioral studies suggested heightened impact of emotionally laden perceptual input in schizophrenia spectrum disorders, in particular in patients with prominent positive symptoms. De-coupling of prefrontal and posterior cortices during stimulus processing, which is related to loosening of control of the prefrontal cortex over incoming affectively laden information, may underlie this abnormality. Pre-selected groups of individuals with low versus high positive schizotypy (lower and upper quartile of a large screening sample) were tested. During exposure to auditory displays of strong emotions (anger, sadness, cheerfulness), individuals with elevated levels of positive schizotypal symptoms showed lesser prefrontal-posterior coupling (EEG coherence) than their symptom-free counterparts (right hemisphere). This applied to negative emotions in particular and was most pronounced during confrontation with anger. The findings indicate a link between positive symptoms and a heightened impact particularly of threatening emotionally laden stimuli which might lead to exacerbation of positive symptoms and inappropriate behavior in interpersonal situations.

    Full Text Available Punishing norm violations is considered an important motive during rejection of unfair offers in the Ultimatum Game (UG. The present study investigates the impact of the power to punish norm violations on people’s responses to unfairness and associated neural correlates. In the UG condition participants had the power to punish norm violations, while an alternate condition, the Impunity Game (IG, was presented where participants had no power to punish norm violations since rejection only reduced the responder’s income to zero. Results showed that unfair offers were rejected more often in UG compared to IG. At the neural level, anterior insula and dorsal anterior cingulate cortex were more active when participants received and rejected unfair offers in both UG and IG. Moreover, greater dorsolateral prefrontal cortex activity was observed when participants rejected than accepted unfair offers in UG but not in IG. Ventromedial prefrontal cortex activation was higher in UG than IG when unfair offers were accepted as well as when rejecting unfair offers in IG as opposed to UG. Taken together, our results demonstrate that the power to punish norm violations affects not only people’s behavioral responses to unfairness but also the neural correlates of the fairness-related social decision-making process.

    Full Text Available One of the most important issues affecting profitability is to determine the impact of different factors influencing purchasing activities. In this paper, we perform an extensive literature survey to detect different purchasing factors influencing customers' behavior. The factors are categorized in three different groups and they are ranked using analytical network process. The results of our survey indicate that three factors of personal, product and situational play important roles in purchasing impulse.

    Oil sands process-affected water (OSPW) - a byproduct of the oil sands industry in Northern Alberta, Canada - is currently stored in on-site tailings ponds. The goal of the present study was to investigate the interaction of OSPW with the olfactory system and olfactory-mediated behaviours of fish upon the first encounter with OSPW. The response of rainbow trout (Oncorhynchus mykiss) to different concentrations (0.1, 1, and 10%) of OSPW was studied using a choice maze and electro-olfactography (EOG), respectively. The results of the present study showed that rainbow trout are capable of detecting and avoiding OSPW at a concentration as low as 0.1%. Exposure to 1% OSPW impaired (i.e. reduced sensitivity) the olfactory response of rainbow trout to alarm and food cues within 5 min or less. The results of the present study demonstrated that fish could detect and avoid minute concentrations of OSPW. However, if fish were exposed to OSPW-contaminated water and unable to escape, their olfaction would be impaired. Copyright © 2017 Elsevier Ltd. All rights reserved.

    To investigate whether making performance predictions affects prospective memory (PM) processing, we asked one group of participants to predict their performance in a PM task embedded in an ongoing task and compared their performance with a control group that made no predictions. A third group gave not only PM predictions but also ongoing-task predictions. Exclusive PM predictions resulted in slower ongoing-task responding both in a nonfocal (Experiment 1) and in a focal (Experiment 2) PM task. Only in the nonfocal task was the additional slowing accompanied by improved PM performance. Even in the nonfocal task, however, was the correlation between ongoing-task speed and PM performance reduced after predictions, suggesting that the slowing was not completely functional for PM. Prediction-induced changes could be avoided by asking participants to additionally predict their performance in the ongoing task. In sum, the present findings substantiate a role of metamemory for attention-allocation strategies of PM. Copyright © 2013 Elsevier Inc. All rights reserved.

    Acute toxicity of oil sands process-affected water (OSPW) is caused by its complex mixture of bitumen-derived organics, but the specific chemical classes that are most toxic have not been demonstrated. Here, effects-directed analysis was used to determine the most acutely toxic chemical classes in OSPW collected from the world's first oil sands end-pit lake. Three sequential rounds of fractionation, chemical analysis (ultrahigh resolution mass spectrometry), and acute toxicity testing (96 h fathead minnow embryo lethality and 15 min Microtox bioassay) were conducted. Following primary fractionation, toxicity was primarily attributable to the neutral extractable fraction (F1-NE), containing 27% of original organics mass. In secondary fractionation, F1-NE was subfractionated by alkaline water washing, and toxicity was primarily isolated to the ionizable fraction (F2-NE2), containing 18.5% of the original organic mass. In the final round, chromatographic subfractionation of F2-NE2 resulted in two toxic fractions, with the most potent (F3-NE2a, 11% of original organic mass) containing predominantly naphthenic acids (O2(-)). The less-toxic fraction (F3-NE2b, 8% of original organic mass) contained predominantly nonacid species (O(+), O2(+), SO(+), NO(+)). Evidence supports naphthenic acids as among the most acutely toxic chemical classes in OSPW, but nonacidic species also contribute to acute toxicity of OSPW.

    A collaborative theory of narrative story-telling was tested in two experiments that examined what listeners do and their effect on the narrator. In 63 unacquainted dyads (81 women and 45 men), a narrator told his or her own close-call story. The listeners made 2 different kinds of listener responses: Generic responses included nodding and vocalizations such as "mhm." Specific responses, such as wincing or exclaiming, were tightly connected to (and served to illustrate) what the narrator was saying at the moment. In experimental conditions that distracted listeners from the narrative content, listeners made fewer responses, especially specific ones, and the narrators also told their stories significantly less well, particularly at what should have been the dramatic ending. Thus, listeners were co-narrators both through their own specific responses, which helped illustrate the story, and in their apparent effect on the narrator's performance. The results demonstrate the importance of moment-by-moment collaboration in face-to-face dialogue.

  7. Theoretical perspectives on narrative inquiry.

    1998-04-01

    Narrative inquiry is gaining momentum in the field of nursing. As a research approach it does not have any single heritage of methodology and its practitioners draw upon diverse sources of influence. Central to all narrative inquiry however, is attention to the potential of stories to give meaning to people's lives, and the treatment of data as stories. This is the first of two papers on the topic and addresses the theoretical influences upon a particular narrative inquiry into nursing scholars and scholarship. The second paper, Conducting a narrative analysis, describes the actual narrative analysis as it was conducted in this same study. Together, the papers provide sufficient detail for others wishing to pursue a similar approach to do so, or to develop the ideas and procedures according to their own way of thinking. Within this first theoretical paper, perspectives from Jerome Bruner (1987) and Wade Roof (1993) are outlined. These relate especially to the notion of stories as 'imaginative constructions' and as 'cultural narratives' and as such, highlight the profound importance of stories as being individually and culturally meaningful. As well, perspectives on narrative inquiry from nursing literature are highlighted. Narrative inquiry in this instance lies within the broader context of phenomenology.

  9. Narrative ethics in nursing for persons with intellectual disabilities.

    Meininger, Herman P

    2005-04-01

    Both in The Netherlands and in Britain, practices of 'life story work' have emerged in nursing for persons with intellectual disabilities. The narrative approach to care and support may at the same time be considered as an attempt to compensate for the 'disabled authorship' of many persons with intellectual disabilities and as a sign of controversy with standard practices of diagnosis and treatment that tend to neglect the personal identities of both clients and care givers, their particular historical and relational contexts and their spiritual needs. This paper argues that narrative ethics not only offers an appropriate moral framework for practices of life story work, but that these practices are a narrative ethics in action. Starting with an account of the concept of 'life story work' as it has been introduced in nursing practices in the field of intellectual disability, the paper explains its relationship with key characteristics of narrative ethics. The teleological dimension in narrative ethics and in practices of life story work sparks off a dialectic process of understanding of the client and self-understanding of the care giver. It also invites a respect for life in its openness toward the future and presupposes an openness toward other possible versions of the life narrative. The phenomenological and hermeneutic-interpretative methodologies in narrative ethics aim at a 'sudden moment of intimacy' in relationships of nurses and clients. The 'epiphany' of this essential moment of recognition, insight and engagement cannot, however, be brought about by methodology.

    2014-04-01

    Prior claims that color categories affect color perception are confounded by inequalities in the color space used to equate same- and different-category colors. Here, we equate same- and different-category colors in the number of just-noticeable differences, and measure event-related potentials (ERPs) to these colors on a visual oddball task to establish if color categories affect perceptual or post-perceptual stages of processing. Category effects were found from 200 ms after color presentation, only in ERP components that reflect post-perceptual processes (e.g., N2, P3). The findings suggest that color categories affect post-perceptual processing, but do not affect the perceptual representation of color.

    Habermas, Tilmann; Döll-Hentschker, Susanne

    2017-05-01

    We ask which are the clinically relevant qualities of narratives in psychotherapy and how they can be measured. On the background of psychoanalytic assumptions and narrative theory, we propose to measure formal narrative processes which stay close to the linguistic surface, because these escape conscious control. We propose five aspects of narratives to be especially sensitive to distortions and therefore prone to change in successful therapies: (1) The actual chronological, stepwise narrating of events, (2) the intentional structuring of events, or emplotment, (3) the immediate evaluation, (4) the reflected interpretation of events, and finally (5) the consistency and completeness of the narrative. For each aspect we discuss ways to measure them. Finally the aspects are illustrated with excerpts from a series of diagnostic interviews. Implications for the analysis of the co-narrative role of the therapist are suggested.

  15. The Narrative Function of Signs in Rabe’e Tale of Attar’s Elahi Nameh

    2013-05-01

    Using the descriptive-analytical method, this article aims to analyze semiotically the tale of “Ka’b daughter and her love and poem”. This tale, which has a direct relationship with the general narrative structure of Elahi Nameh regarding structure and meaning, shows that plot progression in this tale is done via opposition and tension in the elements of two codes of power and love that is, being within the two codes, each element accepts narratively and linguistically a form and meaning which is proportionate to that code and the processing of tale’s narrative elements takes place via such oppositions. Regarding this matter and the point that such tale has been stated within the overall mystical narrative of Elahi Nameh, it can be said that all signs in this tale become meaningful structurally in a process of substitution within a wider system named mysticism. These are the rules and conventions of mysticism which affect the formation of narrative.

    Decision aids (DAs) are non-directive communication tools that help patients make value-consistent health-care decisions. However, most DAs have been developed without an explicit theoretical framework, resulting in a lack of understanding of how DAs achieve outcomes. To investigate the effect of promoting affective vs. deliberative processing on DA effectiveness based on dual-process theory. One hundred and forty-eight female university students participated in a randomized controlled experiment with three conditions: emotion-focused, information-focused and control. Preference-value consistency, knowledge, decisional conflict and satisfaction were compared across the conditions using planned contrast analyses. The intervention comprised two different DAs and instructional manipulations. The emotion-focused condition received a modified DA with affective content and instructions to induce an affective reaction. The information-focused and control conditions received the same DA without the affective content. The information-focused condition received additional instructions to induce deliberative processing. Controlling for the experiment-wise error rate at P processing may hinder value-consistent decision making, while deliberative processing may enhance decisional satisfaction. This investigation of the effect of affective and deliberative processes in DA-supported decision making has implications for the design and use of DAs. DA effectiveness may be enhanced by incorporating a simple instruction to focus on the details of the information. © 2014 John Wiley & Sons Ltd.

    Individuals with IBS report higher levels of psychological distress compared to healthy controls. Distress has been associated with emotional processing difficulties but studies have not explored how the relationship between distress and emotional processing affects IBS. There is little research on the role of positive affect (PA) in IBS. (a) If difficulties in self-reported emotional processing are associated with affect and IBS measures (i.e., symptom severity, interference in life roles) (b1) If affect mediates the relationship between emotional processing and IBS measures (b2) Alternative model: if affect mediates the relationship between IBS and emotional processing (c) If PA moderates the relationship between distress and IBS. Participants with a confirmed diagnosis of IBS (n=558) completed a questionnaire including measures of emotional processing (i.e., unhelpful beliefs about negative emotions, impoverished emotional experience), distress, PA, and IBS symptoms/interference. Mediation and moderation analyses were conducted with Maximum Likelihood Estimation. Distress and PA mediated or partly mediated the relationship between unhelpful beliefs about negative emotions/impoverished emotional experience and both IBS measures. The alternative models were also valid, suggesting a two-way relationship between emotional processing and IBS through affect. PA did not moderate the relationship between distress and IBS. Future interventions in IBS may benefit from not only targeting the management of physical symptoms and their daily impact but also aspects related to the experience of both negative and positive affect, and the acceptance and expression of negative emotions. Longitudinal studies are needed to confirm causal relationships within the explored models. Copyright © 2017 Elsevier Inc. All rights reserved.

    Full Text Available Narrative is a system of understanding that we use to construct and express meaning in our daily lives. The stories we narrate are not justresources for the development and presentation of the individual self; they allow us to see how identity is constructed within social and culturalworlds (Bruner, 1990. Schools and communities play a powerful role in shaping students identities; the ways in which stories are told and theidentities they create are influenced by the environment in which they take place. In this paper, by using excerpts from a conversation I hadwith a High School student in an urban school in Bogotá, I will discuss how narrative analysis can be used to understand the way studentsconstruct their identities within their schools and communities. First, I will present the theoretical contexts linking narrative with self-construction.Next, I will discuss the methodological implications in the process of collecting and representing experiences highlighting the possibilities ofnarrative to make visible the construction of identities. Then pieces of a narrative told in a research interview will be analyzed illustrating differentapproaches of narrative analysis. The paper will conclude with a section that outlines the implications of using narrative in educational research.

    Despite the physiological importance of alpha-tocopherol (AT), the molecular mechanisms involved in maintaining cellular and tissue tocopherol levels remain to be fully characterized. Scavenger receptor B1 (SRB1), one of a large family of scavenger receptors, has been shown to facilitate AT transfer from HDL to peripheral tissues via apo A-1-mediated processes and to be important in the delivery of AT to the lung cells. In the present studies the effects of age and two environmental oxidants ozone (O 3 ) (0.25 ppm 6 h/day) and cigarette smoke (CS) (60 mg/m 3 6 h/day) for 4 days on selected aspects of AT transport in murine lung tissues were assessed. While AT levels were 25% higher (p 3 or CS at the doses used had no effect. Gene expression levels, determined by RT-PCR of AT transport protein (ATTP), SRB1, CD36, ATP binding cassette 3 (ABCA3) and ABCA1 and protein levels, determined by Western blots for SRB1, ATTP and ABCA1 were assessed. Aged mouse lung showed a lower levels of ATTP, ABCA3 and SRB1 and a higher level CD36 and ABCA1. Acute exposure to either O 3 or CS induced declines in ATTP and SRB1 in both aged and young mice lung. CD36 increased in both young and aged mice lung upon exposure to O 3 and CS. These findings suggest that both age and environmental oxidant exposure affect pathways related to lung AT homeostasis and do so in a way that favors declines in lung AT. However, given the approach taken, the effects cannot be traced to changes in these pathways or AT content in any specific lung associated cell type and thus highlight the need for further follow-up studies looking at specific lung associated cell types

    2018-01-01

    Full Text Available The influences of hot air drying (AD, medium- and short-wave infrared drying (IR, instant controlled pressure drop drying (DIC, and vacuum freeze drying (FD on cell wall polysaccharide modification were studied, and the relationship between the modifications and texture properties was analyzed. The results showed that the DIC treated apple chips exhibited the highest crispness (92 and excellent honeycomb-like structure among all the dried samples, whereas the FD dried apple chips had low crispness (10, the minimum hardness (17.4 N, and the highest volume ratio (0.76 and rehydration ratio (7.55. Remarkable decreases in the contents of total galacturonic acid and the amounts of water extractable pectin (WEP were found in all the dried apple chips as compared with the fresh materials. The highest retention of WEP fraction (102.7 mg/g AIR was observed in the FD dried apple chips, which may lead to a low structural rigidity and may be partially responsible for the lower hardness of the FD apple chips. In addition, the crispness of the apple chips obtained by DIC treatment, as well as AD and IR at 90°C, was higher than that of the samples obtained from the other drying processes, which might be due to the severe degradation of pectic polysaccharides, considering the results of the amounts of pectic fractions, the molar mass distribution, and concentrations of the WEP fractions. Overall, the data suggested that the modifications of pectic polysaccharides of apple chips, including the amount of the pectic fractions and their structural characteristics and the extent of degradation, significantly affect the texture of apple chips.

    We performed our study in the Dry Puna of the southern Peruvian Andes. Through a comparative approach we aimed to assess the effects of the two management systems, low grazing pressure by wild camelids vs. high grazing pressure by domestic livestock and periodic burning. Our general hypothesis was that the traditional high disturbance regime affects the dry Puna species diversity and composition through modifications of the magnitude of plant-plant-interactions and changes of the community structure due to shifts in species dominance. In 40 plots of 10 × 10 m, the cover value of each species was recorded and the species richness, floristic diversity, and community similarity of each treatment were compared. For each disturbance regime, differences of soil features (organic matter, carbon/nitrogen ratio, and potassium content) were tested. To evaluate plant-plant interactions, 4 linear transect divided into 500 plots of 10 × 10 cm were laid out and co-occurrence analysis was performed. We found that different disturbance regimes were associated with differences in the floristic composition, and that the high disturbance condition had lower species diversity and evenness. A decrease of tall species such as Festuca orthophylla and increase of dwarf and spiny Tetraglochin cristatum shrubs was observed as well. In addition, different disturbance intensities caused differences in the functional composition of the plant communities, since species with avoidance strategies are selected by high grazing pressure. High disturbance intensity was also associated to differences of soil features and to different clumped spatial structure of the dry Puna. Our results indicate also that: positive interactions are often species-specific mainly depending on the features of nurse and beneficiary species; the importance of positive interaction is higher at low grazing pressure than at high disturbance intensity; the magnitude and direction of the herbivory-mediated facilitation

    2009-02-01

    Full Text Available Abstract Background Viral infection and neoplastic transformation trigger endoplasmic reticulum (ER stress. Thus, a large proportion of the cells that must be recognized by the immune system are stressed cells. Cells respond to ER stress by launching the unfolded protein response (UPR. The UPR regulates the two key processes that control major histocompatibility complex class I (MHC I-peptide presentation: protein synthesis and degradation. We therefore asked whether and how the UPR impinges on MHC I-peptide presentation. Results We evaluated the impact of the UPR on global MHC I expression and on presentation of the H2Kb-associated SIINFEKL peptide. EL4 cells stably transfected with vectors coding hen egg lysozyme (HEL-SIINFEKL protein variants were stressed with palmitate or exposed to glucose deprivation. UPR decreased surface expression of MHC I but did not affect MHC I mRNA level nor the total amount of intracellular MHC I proteins. Impaired MHC I-peptide presentation was due mainly to reduced supply of peptides owing to an inhibition of overall protein synthesis. Consequently, generation of H2Kb-SIINFEKL complexes was curtailed during ER stress, illustrating how generation of MHC I peptide ligands is tightly coupled to ongoing protein synthesis. Notably, the UPR-induced decline of MHC I-peptide presentation was more severe when the protein source of peptides was localized in the cytosol than in the ER. This difference was not due to changes in the translation rates of the precursor proteins but to increased stability of the cytosolic protein during ER stress. Conclusion Our results demonstrate that ER stress impairs MHC I-peptide presentation, and that it differentially regulates expression of ER- vs. cytosol-derived peptides. Furthermore, this work illustrates how ER stress, a typical feature of infected and malignant cells, can impinge on cues for adaptive immune recognition.

    Acid mine drainage (AMD) in a watershed provides potential sources of pollutants for surface and subsurface waters that can deteriorate water quality. Between March and early August 2011, water samples were collected from two streams in South Korea, one dominantly draining a watershed with carbonate bedrock affected by coal mines and another draining a watershed with silicate bedrock and a relatively undisturbed catchment area. The objective of the study was to identify the sources and processes controlling water chemistry, which was dependent on bedrock and land use. In the Odae stream (OS), the stream in the silicate-dominated catchment, Ca, Na, and HCO 3 were the dominant ions and total dissolved solids (TDS) was low (26.1–165 mg/L). In the Jijang stream (JS), in the carbonate-dominated watershed, TDS (224–434 mg/L) and ion concentrations were typically higher, and Ca and SO 4 were the dominant ions due to carbonate weathering and oxidation of pyrite exposed at coal mines. Dual isotopic compositions of sulfate (δ 34 S SO4 and δ 18 O SO4 ) verified that the SO 4 in JS is derived mainly from sulfide mineral oxidation in coal mines. Cl in JS was highest upstream and decreased progressively downstream, which implies that pollutants from recreational facilities in the uppermost part of the catchment are the major source governing Cl concentrations within the discharge basin. Dual isotopic compositions of nitrate (δ 15 N NO3 and δ 18 O NO3 ) indicated that NO 3 in JS is attributable to nitrification of soil organic matter but that NO 3 in OS is derived mostly from manure. Additionally, the contributions of potential anthropogenic sources to the two streams were estimated in more detail by using a plot of δ 34 S SO4 and δ 15 N NO3 . This study suggests that the dual isotope approach for sulfate and nitrate is an excellent additional tool for elucidating the sources and processes controlling the water chemistry of streams draining watersheds having different

    In cybersecurity forensics and incident response, the story of what has happened is the most important artifact yet the one least supported by tools and techniques. Existing tools focus on gathering and manipulating low-level data to allow an analyst to investigate exactly what happened on a host system or a network. Higher-level analysis is usually left to whatever ad hoc tools and techniques an individual may have developed. We discuss visual representations of narrative in the context of cybersecurity incidents with an eye toward multi-scale illustration of actions and actors. We envision that this representation could smoothly encompass individual packets on a wire at the lowest level and nation-state-level actors at the highest. We present progress to date, discuss the impact of technical risk on this project and highlight opportunities for future work.

    To describe and recommend a variety of data analysis methods when engaging in narrative research using story as an aid to nursing students' learning. Narrative research methodology is used in many nursing research studies. However, narrative research reports are generally unspecific regarding the analysis and interpretive process. This article examines the qualitative analytical approaches of Lieblich et al's ( 1998 ) narrative processes of holistic content and analysis of form, incorporated as overarching theories. To support these theories and to provide a more rounded analytical process, other authors' work is included. Approaching narrative analysis from different perspectives is recommended. For each cycle of analysis, it is important to conceptualise the analysis using descriptors drawn from the initial literature review and the initial text. Rigour and transparency are foremost, and tables are generated that reflect each stage of the analysis. The final stage of analysis is to clearly report, organise and present findings to reflect the richly varied and diverse potential of stories. Engaging in narrative research and then dealing with the large quantities of data to analyse can be daunting, difficult to manage and appear complex. It is also challenging and rewarding. With clear descriptors, examining the data using multiple lenses can serve to develop a greater level of insight into understanding nursing students' learning from their clinical experiences, presented as stories, when involved in the care of individuals. There are many approaches to narrative analysis in nursing research and it can be difficult to establish the main research approach best suited to the study. There is no single way to define narrative analysis and a combination of strategies can be applied.

    Full Text Available Based on 145 process innovation teams, we have studied factors supporting team learning and their impact on the success of the process innovation projects. As a result, we have found that team vision, recording and reviewing project related information, filing, following a structural development process and co-location of team members are factors supporting team learning and project success. Also, two dimensions of learning, information acquisition and information implementation, are positively related to the success of the process innovation projects

  10. Credibility judgments of narratives: language, plausibility, and absorption.

    Two experiments were conducted in order to find out whether textual features of narratives differentially affect credibility judgments made by judges having different levels of absorption (a disposition associated with rich visual imagination). Participants in both experiments were exposed to a textual narrative and requested to judge whether the narrator actually experienced the event he described in his story. In Experiment 1, the narrative varied in terms of language (literal, figurative) and plausibility (ordinary, anomalous). In Experiment 2, the narrative varied in terms of language only. The participants' perceptions of the plausibility of the story described and the extent to which they were absorbed in reading were measured. The data from both experiments together suggest that the groups applied entirely different criteria in credibility judgments. For high-absorption individuals, their credibility judgment depends on the degree to which the text can be assimilated into their own vivid imagination, whereas for low-absorption individuals it depends mainly on plausibility. That is, high-absorption individuals applied an experiential mental set while judging the credibility of the narrator, whereas low-absorption individuals applied an instrumental mental set. Possible cognitive mechanisms and implications for credibility judgments are discussed.

    2013-03-01

    Full Text Available The present study provides a brief overview of the ‘narrative turn’ in counselling and adopts a narrative perspective and analysis to explore Greek mothers’ experiences, and meaning making of involvement in their children’s learning. Data were collected via ten narrative interviews (life-history/biographical narrative. Participants portrayed a variety of conceptions and practices regarding children’s learning and parental participation. Mothers’ stories depicted parental engagement as a complex, multifaceted, flexible and multivoiced construct which can take various forms and is open to change. The findings can inform and enrich counselling practice and prevention efforts including parenting training programmes, family community programmes and home-school link initiatives. Of particular interest for counsellors and therapists are stories of functional and dysfunctional parental involvement practices, school expectations and cultural scripts, the working mother, identity and the process of change.

  12. "Borges and I," A Narrative Sleight of Hand

    Armando F. Zubizarreta

    1998-06-01

    Full Text Available Because of its autobiographical appearance, critics have paid little attention to the narrative of "Borges and I" which is so masterfully handled that its complex and transparent texture is almost invisible. A close analysis shows, however, that, in the confessional mode, the two individuals—I and Borges—are true characters involved in a narrative action that is taking place to allow the implementation of vengeance. By focusing on his victim's experience, the narrating I offers an attractive bait to his victimizer, Borges. Borges, the writer, driven by a compulsive pattern of stealing, unsuspectingly takes over the victim's grievances against him by virtue of his own writing. To unveil those basic elements of narrative at play in this short story, the participation of an active reader, as witness to the process and as recipient of the indicting text, is actually demanded. Thus, "Borges and I" may be considered a superb example of Jorge Luis Borges's art.

    2011-10-01

    In this article, dreams are seen as stories within a self-narrative. Dream stories, like all other stories, are told in an effort to make sense of experiences. Here, dream content is linked to current concerns, some aspects of which are not given voice in waking. Dreams depict restricting themes but also openings in self-narratives. Several examples are provided of how dreams can be linked to early, middle, and late therapy phases associated with recognizing, challenging, revising, and maintaining a revising stance. It is further suggested that dream stories can be used to trace, facilitate, and evaluate the process of reconstructing self-narratives. Finally, a number of therapeutic interventions are briefly presented to facilitate the work of narrative-informed family therapists working with individuals, families, and groups. © 2011 American Association for Marriage and Family Therapy.

    Full Text Available In the article on the basis of analyzing theoretical sources and practical experience some scientists’ works are disclosed, which deal with using and designing digital narratives in future Ukrainian language and literature teachers’ training, to develop a personality’s information and digital competence. It is reported that the themes, which are focused on postgraduate students’ acquainting with digital technologies of studying linguistic subjects at university, in specialized classes in secondary school, and a new type of educational institutions, should be introduced into language and methodological training. The author emphasizes on the relevance and importance of using digital narratives for democratization and humanization, the inspiration of the educational process. Narratives (stories in literary works, letters, confessions, biographies, diaries, comments, portrait sketches, pedagogical aphorisms, scripts, summaries of lessons with notes in the margins and others, biographical and pedagogical narratives provide information about the events, situations, taking into account individual reflexed experience of outstanding teachers. If students have an opportunity to develop skills of making narratives, they will gradually get communicative competences and feeling of confidence in their own ability that are necessary in the life. The works by M. Leshchenko and L. Tymchuk that are devoted to studying biography narratives are overviewed. The author suggests her own works of studying biography narratives of outstanding personalities (O. Zakharenko, I. Ziaziun, N. Voloshyna, L. Matsko and others. Digital narrative is characterized as a dynamic means of sending information messages in which a word, an image and sound are expressed in a joint digital code; as multimedia project that combines text, a picture, audio and video files in a short video clip.

    2016-06-01

    We describe how we think of identity as relational, distributed, performed, and fluid, and we illustrate the use of this conceptualization within a narrative worldview. Drawing on the work of Michael White, we describe how this relational view of identity leads to therapeutic responses that give value to interconnection across multiple contexts and that focus on becoming rather than on being. We show how a narrative worldview helps focus on the relational, co-evolving perspective that was the basis of our early attraction to family therapy. We offer detailed examples from our work of practices that help us stay firmly situated in a relational worldview that is counter to the pervasive influence of individualism in our contemporary culture. © 2016 Family Process Institute.

    2015-07-01

    Research papers present us with the summaries of scholars' work; what we readers do not see are the struggles behind the decision to choose one methodology over another. A student's mental health portfolio contained a narrative that led to an exploration of the most appropriate methodology for a projected study of clinical anecdotes told by nurses who work in mental health settings to undergraduates and new recruits about mental health nursing. This paper describes the process of struggle, beginning with the student's account, before posing a number of questions needing answers before the choice of the most appropriate methodology. We argue, after discussing the case for the use of literary analysis, discourse analysis, symbolic interactionism, hermeneutics, and narrative research, that case study research is the methodology of choice. Case study is frequently used in educational research and is sufficiently flexible to allow for an exploration of the phenomenon. © 2014 Wiley Periodicals, Inc.

    2016-06-01

    Full Text Available This article describes the methodology and the outcomes of an empirical study of conflict narratives. The narratological analysis deployed narratological catego­ries in the structuralist tradition based on Genette and was conducted with the help of the text annotation tool CATMA. The analysis aimed at covering as many narratological phenomena as possible by establishing 14 fields of narrato­logical phenomena that were annotated in a corpus of 39 factual narratives about situations at the workplace with and without conflicts. The evaluation of approximately 28,000 annotations brought to light a series of interrelations be­tween narratological phenomena and the presence or absence of conflicts in the narratives. Additionally, this approach led to the identification of some over­sights of narrative theory by detecting hitherto unnoticed interrelations among narratological concepts.

  20. Natural analogues for processes affecting disposal of high-level radioactive waste in the vadose zone

    Stuckless, J. S.

    2003-04-01

    Natural analogues can contribute to understanding and predicting the performance of subsystems and processes affecting a mined geologic repository for high-level radioactive waste in several ways. Most importantly, analogues provide tests for various aspects of systems of a repository at dimensional scales and time spans that cannot be attained by experimental study. In addition, they provide a means for the general public to judge the predicted performance of a potential high-level nuclear waste repository in familiar terms such that the average person can assess the anticipated long-term performance and other scientific conclusions. Hydrologists working on the Yucca Mountain Project (currently the U.S. Department of Energy's Office of Repository Development) have modeled the flow of water through the vadose zone at Yucca Mountain, Nevada and particularly the interaction of vadose-zone water with mined openings. Analogues from both natural and anthropogenic examples confirm the prediction that most of the water moving through the vadose zone will move through the host rock and around tunnels. This can be seen both quantitatively where direct comparison between seepage and net infiltration has been made and qualitatively by the excellent degree of preservation of archaeologic artifacts in underground openings. The latter include Paleolithic cave paintings in southwestern Europe, murals and artifacts in Egyptian tombs, painted subterranean Buddhist temples in India and China, and painted underground churches in Cappadocia, Turkey. Natural analogues also suggest that this diversion mechanism is more effective in porous media than in fractured media. Observations from natural analogues are also consistent with the modeled decrease in the percentage of infiltration that becomes seepage with a decrease in amount of infiltration. Finally, analogues, such as tombs that have ben partially filled by mud flows, suggest that the same capillary forces that keep water in the

  1. Nanoscale Chemical Processes Affecting Storage Capacities and Seals during Geologic CO2 Sequestration.

    2017-07-18

    Geologic CO 2 sequestration (GCS) is a promising strategy to mitigate anthropogenic CO 2 emission to the atmosphere. Suitable geologic storage sites should have a porous reservoir rock zone where injected CO 2 can displace brine and be stored in pores, and an impermeable zone on top of reservoir rocks to hinder upward movement of buoyant CO 2 . The injection wells (steel casings encased in concrete) pass through these geologic zones and lead CO 2 to the desired zones. In subsurface environments, CO 2 is reactive as both a supercritical (sc) phase and aqueous (aq) species. Its nanoscale chemical reactions with geomedia and wellbores are closely related to the safety and efficiency of CO 2 storage. For example, the injection pressure is determined by the wettability and permeability of geomedia, which can be sensitive to nanoscale mineral-fluid interactions; the sealing safety of the injection sites is affected by the opening and closing of fractures in caprocks and the alteration of wellbore integrity caused by nanoscale chemical reactions; and the time scale for CO 2 mineralization is also largely dependent on the chemical reactivities of the reservoir rocks. Therefore, nanoscale chemical processes can influence the hydrogeological and mechanical properties of geomedia, such as their wettability, permeability, mechanical strength, and fracturing. This Account reviews our group's work on nanoscale chemical reactions and their qualitative impacts on seal integrity and storage capacity at GCS sites from four points of view. First, studies on dissolution of feldspar, an important reservoir rock constituent, and subsequent secondary mineral precipitation are discussed, focusing on the effects of feldspar crystallography, cations, and sulfate anions. Second, interfacial reactions between caprock and brine are introduced using model clay minerals, with focuses on the effects of water chemistries (salinity and organic ligands) and water content on mineral dissolution and

    Moon, Hongsik

    What is the impact of multicore and associated advanced technologies on computational software for science? Most researchers and students have multicore laptops or desktops for their research and they need computing power to run computational software packages. Computing power was initially derived from Central Processing Unit (CPU) clock speed. That changed when increases in clock speed became constrained by power requirements. Chip manufacturers turned to multicore CPU architectures and associated technological advancements to create the CPUs for the future. Most software applications benefited by the increased computing power the same way that increases in clock speed helped applications run faster. However, for Computational ElectroMagnetics (CEM) software developers, this change was not an obvious benefit - it appeared to be a detriment. Developers were challenged to find a way to correctly utilize the advancements in hardware so that their codes could benefit. The solution was parallelization and this dissertation details the investigation to address these challenges. Prior to multicore CPUs, advanced computer technologies were compared with the performance using benchmark software and the metric was FLoting-point Operations Per Seconds (FLOPS) which indicates system performance for scientific applications that make heavy use of floating-point calculations. Is FLOPS an effective metric for parallelized CEM simulation tools on new multicore system? Parallel CEM software needs to be benchmarked not only by FLOPS but also by the performance of other parameters related to type and utilization of the hardware, such as CPU, Random Access Memory (RAM), hard disk, network, etc. The codes need to be optimized for more than just FLOPs and new parameters must be included in benchmarking. In this dissertation, the parallel CEM software named High Order Basis Based Integral Equation Solver (HOBBIES) is introduced. This code was developed to address the needs of the

    Acid mine drainage (AMD) in a watershed provides potential sources of pollutants for surface and subsurface waters that can deteriorate water quality. Between March and early August 2011, water samples were collected from two streams in South Korea, one dominantly draining a watershed with carbonate bedrock affected by coal mines and another draining a watershed with silicate bedrock and a relatively undisturbed catchment area. The objective of the study was to identify the sources and processes controlling water chemistry, which was dependent on bedrock and land use. In the Odae stream (OS), the stream in the silicate-dominated catchment, Ca, Na, and HCO{sub 3} were the dominant ions and total dissolved solids (TDS) was low (26.1–165 mg/L). In the Jijang stream (JS), in the carbonate-dominated watershed, TDS (224–434 mg/L) and ion concentrations were typically higher, and Ca and SO{sub 4} were the dominant ions due to carbonate weathering and oxidation of pyrite exposed at coal mines. Dual isotopic compositions of sulfate (δ{sup 34}S{sub SO4} and δ{sup 18}O{sub SO4}) verified that the SO{sub 4} in JS is derived mainly from sulfide mineral oxidation in coal mines. Cl in JS was highest upstream and decreased progressively downstream, which implies that pollutants from recreational facilities in the uppermost part of the catchment are the major source governing Cl concentrations within the discharge basin. Dual isotopic compositions of nitrate (δ{sup 15}N{sub NO3} and δ{sup 18}O{sub NO3}) indicated that NO{sub 3} in JS is attributable to nitrification of soil organic matter but that NO{sub 3} in OS is derived mostly from manure. Additionally, the contributions of potential anthropogenic sources to the two streams were estimated in more detail by using a plot of δ{sup 34}S{sub SO4} and δ{sup 15}N{sub NO3}. This study suggests that the dual isotope approach for sulfate and nitrate is an excellent additional tool for elucidating the sources and processes

  7. Enhanced Geothermal Systems Research and Development: Models of Subsurface Chemical Processes Affecting Fluid Flow

    2008-05-29

    Successful exploitation of the vast amount of heat stored beneath the earth’s surface in hydrothermal and fluid-limited, low permeability geothermal resources would greatly expand the Nation’s domestic energy inventory and thereby promote a more secure energy supply, a stronger economy and a cleaner environment. However, a major factor limiting the expanded development of current hydrothermal resources as well as the production of enhanced geothermal systems (EGS) is insufficient knowledge about the chemical processes controlling subsurface fluid flow. With funding from past grants from the DOE geothermal program and other agencies, we successfully developed advanced equation of state (EOS) and simulation technologies that accurately describe the chemistry of geothermal reservoirs and energy production processes via their free energies for wide XTP ranges. Using the specific interaction equations of Pitzer, we showed that our TEQUIL chemical models can correctly simulate behavior (e.g., mineral scaling and saturation ratios, gas break out, brine mixing effects, down hole temperatures and fluid chemical composition, spent brine incompatibilities) within the compositional range (Na-K-Ca-Cl-SO4-CO3-H2O-SiO2-CO2(g)) and temperature range (T < 350°C) associated with many current geothermal energy production sites that produce brines with temperatures below the critical point of water. The goal of research carried out under DOE grant DE-FG36-04GO14300 (10/1/2004-12/31/2007) was to expand the compositional range of our Pitzer-based TEQUIL fluid/rock interaction models to include the important aluminum and silica interactions (T < 350°C). Aluminum is the third most abundant element in the earth’s crust; and, as a constituent of aluminosilicate minerals, it is found in two thirds of the minerals in the earth’s crust. The ability to accurately characterize effects of temperature, fluid mixing and interactions between major rock-forming minerals and hydrothermal and

  9. Losing the Plot: Narrative, Counter-Narrative and Violent Extremism

    Directory of Open Access Journals (Sweden)

    2017-05-01

    Full Text Available Counter-terrorist practitioners and policy makers appear to be very interested in narrative. They often describe the worldview of violent Islamist groups and movements as the ‘jihadi narrative’, while their efforts to confront terrorist propaganda are usually labelled as ‘counter-narrative’ or ‘alternative narrative’. However, while the counter-narrative approach has gained widespread acceptance in governments, think-tanks and civil society organisations, it is built on very shaky theoretical and empirical foundations. Some valuable theoretical contributions to the study of violent extremist narrative have been made by psychologists in particular, but there is one discipline which is conspicuous by its absence from the field: literary studies. This paper makes a case for the value of studying violent extremist narratives as narratives in the literary sense. By employing the tools and techniques of literary criticism, violent extremist communication can be revealed as not only potentially persuasive, but also creative and aesthetically appealing: terrorists inspire their followers, they don’t merely persuade them. Understanding the creative sources of this inspiration is vital if counter-narrative is to succeed in presenting an alternative to the propaganda of violent extremist groups.

    2018-01-01

    Conceptualizing affect as a complex nonlinear dynamic process, we used latent class extended mixed models (LCMM) to understand whether there were unobserved groupings in a dataset including longitudinal measures. Our aim was to identify affect profiles over time in people vicariously exposed to terrorism, studying their relations with personality traits. The participants were 193 university students who completed online measures of affect during the seven days following two terrorist attacks (Paris, November 13, 2015; Brussels, March 22, 2016); Big Five personality traits; and antecedents of affect. After selecting students whose negative affect was influenced by the two attacks (33%), we analysed the data with the LCMM package of R. We identified two affect profiles, characterized by different trends over time: The first profile comprised students with lower positive affect and higher negative affect compared to the second profile. Concerning personality traits, conscientious-ness was lower for the first profile compared to the second profile, and vice versa for neuroticism. Findings are discussed for both their theoretical and applied relevance.

    Using art as a process to help children externalize complex feelings can add another layer of assessment in the primary care setting. In the face of trauma, drawing may help children gain symbolic control over events that are confusing and frightening. Through examples of children who were affected by Hurricane Katrina, this article describes the use of drawings and narratives to understand children's experiences related to traumatic displacement. Recommendations include using a developmental lens to understanding children's art, asking children to talk about their drawings, and considering the significance of place for children who have been traumatically displaced.

    2015-11-01

    Full Text Available This article elaborates on the sixth movement of a postfoundational notion of practical theology and is concerned with giving a description of experiences, which are thickened through interdisciplinary investigation. The experiences of interest are those of the co-researchers who formed part of the larger research study, conducted in 2010, and who were at the time adolescent male orphans, affected by HIV and AIDS, poverty and father abandonment. The research was conducted within the theoretical frameworks of a postfoundational notion of practical theology, narrative therapy and research, and social constructionism. A qualitative research strategy was employed, with the case study design as point of departure in collecting and analysing research data. Various key aspects were investigated with the use of the model of narrative and the seven movements of a postfoundational notion of practical theology. The aim of this article is to provide an illustration of the application of the principles of a postfoundational notion of practical theology, and its sixth movement – an interdisciplinary investigation – as it is applied within this specific research context. Four interdisciplinary conversationalists, each from a different academic field, were invited to reflect on the three narrated stories of the co-researchers. This article, then, gives a report on their feedback and the value of interdisciplinary investigation in aiding, with the understanding of the meaningmaking process behind collected narratives.

    Smorti, Andrea; Pananti, Bianca; Rizzo, Aida

    2010-08-01

    The aims of the present study were to explore how the autobiographical process can lead to a transformation in psychiatric patients' lifestyle, well-being, and self-narrative. Nine participants, aged between 20 and 42 years and affected by axis I psychiatric disorders (DSM IV) were selected to participate in an autobiographical laboratory. Eight to 10 meetings took place, each lasting about an hour, during which autobiographical accounts were collected. At the beginning and end of the autobiographical laboratory, the medical staff completed the Social Functioning Scale to evaluate each patient across 6 dimensions: social engagement, interpersonal ability, prosocial activities, recreation, independence-competence, and independence-performance. The Language Inquiry and Word Count (Pennebaker and Francis, 1996) was used to analyze patients' autobiographical accounts. A comparison between the first and second compilation of the Social Functioning Scale showed significant positive changes across the 6 social dimensions. The analysis of language in the narratives collected in the first and seventh meeting showed how inpatients passed from a narrative that was more centered on the memory of the past to a narrative that was more similar to a conversation and enriched with "insight" terms and the use of verbs in the conjunctive form. The authors interpret these outcomes as being consistent with the improvement that was observed in inpatients' social functioning.

We tested for cross-cultural differences in perception of the MAVs: Japanese listeners were asked to rate the MAVs on several affective dimensions and ratings were compared to those obtained by Canadian listeners. Significant Group x Emotion interactions were observed for ratings of Intensity, Valence, and Arousal. Whereas Intensity and Valence ratings did not differ across cultural groups for sad and happy vocalizations, they were significantly less intense and less negative in Japanese listeners for angry, disgusted, and fearful vocalizations. Similarly, pleased vocalizations were rated as less intense and less positive by Japanese listeners. These results demonstrate important cross-cultural differences in affective perception not just of nonverbal vocalizations expressing positive affect (Sauter et al, 2010, but also of vocalizations expressing basic negative emotions.

    Full Text Available Abstract Background Verbal autopsy (VA, the process of interviewing a deceased’s family or caregiver about signs and symptoms leading up to death, employs tools that ask a series of closed questions and can include an open narrative where respondents give an unprompted account of events preceding death. The extent to which an individual interviewer, who generally does not interpret the data, affects the quality of this data, and therefore the assigned cause of death, is poorly documented. We aimed to examine inter-interviewer reliability of open narrative and closed question data gathered during VA interviews. Methods During the introduction of VA data collection, as part of a larger study in Mchinji district, Malawi, we conducted partner interviews whereby two interviewers independently recorded open narrative and closed questions during the same interview. Closed questions were collected using a smartphone application (mobile-InterVA and open narratives using pen and paper. We used mixed methods of analysis to evaluate the differences between recorded responses to open narratives and closed questions, causes of death assigned, and additional information gathered by open narrative. Results Eighteen partner interviews were conducted, with complete data for 11 pairs. Comparing closed questions between interviewers, the median number of differences was 1 (IQR: 0.5–3.5 of an average 65 answered; mean inter-interviewer concordance was 92 % (IQR: 92–99 %. Discrepancies in open narratives were summarized in five categories: demographics, history and care-seeking, diagnoses and symptoms, treatment and cultural. Most discrepancies were seen in the reporting of diagnoses and symptoms (e.g., malaria diagnosis; only one pair demonstrated no clear differences. The average number of clinical symptoms reported was 9 in open narratives and 20 in the closed questions. Open narratives contained additional information on health seeking and social issues

  17. Narrative journalism as complementary inquiry

    2011-10-01

    Full Text Available Narrative journalism is a method to craft stories worth reading about real people. In this article, we explore the ability of that communicative power to produce insights complementary to those obtainable through traditional qualitative and quantitative research methods. With examples from a study of journalistic narrative as patient involvement in professional rehabilitation, interview data transcribed as stories are analyzed for qualities of heterogeneity, sensibility, transparency, and reflexivity. Building on sociological theories of thinking with stories, writing as inquiry, and public journalism as ethnography, we suggest that narrative journalism as a common practice might unfold dimensions of subjective otherness of the self. Aspiring to unite writing in both transparently confrontational and empathetically dialogic ways, the narrative journalistic method holds a potential to expose dynamics of power within the interview.

    on flexicurity and its implications for labour market transitions, little attention has been paid to the views and experiences of the individuals concerned. The aim of this article is to connect the grand narrative with individual narratives about labour market transitions in the Danish flexicurity system....... On the basis of narrative interviews with skilled workers, this article explores how labour market transitions are experienced by the individual and the role played by national support structures in the individual narratives. The article shows how, for the individual, a transition may prove to be a valuable...... learning experience during which radical career decisions are taken, and how support structures may work to the detriment of such learning and of the principles behind flexicurity. The article points to a reconceptualisation of transitions as important learning opportunities during which (more) adequate...

    Dopaminergic neurotransmission in the ventral striatum may interact with limbic processing of affective stimuli, whereas dorsal striatal dopaminergic neurotransmission can affect habitual processing of emotionally salient stimuli in the pre-frontal cortex. We investigated the dopaminergic neurotransmission in the ventral and dorsal striatum with respect to central processing of affective stimuli in healthy subjects. Subjects were investigated with positron emission tomography and [ 18 F]DOPA for measurements of dopamine synthesis capacity and [ 18 F]DMFP for estimation of dopamine D2 receptor binding potential. Functional magnetic resonance imaging was used to assess the blood-oxygen-level-dependent (BOLD) response to affective pictures, which was correlated with the ratio of [ 18 F]DOPA net influx constant K in app /[ 18 F]DMFP-binding potential (BP N D) in the ventral and dorsal striatum. The magnitude of the ratio in the ventral striatum was positively correlated with BOLD signal increases elicited by negative versus neutral pictures in the right medial frontal gyrus (BA10), right inferior parietal lobe and left post-central gyrus. In the dorsal striatum, the ratio was positively correlated with BOLD signal activation elicited by negative versus neutral stimuli in the left post-central gyrus. The BOLD signal elicited by positive versus neutral stimuli in the superior parietal gyrus was positively correlated with the dorsal and ventral striatal ratio. The correlations of the ratio in the ventral and dorsal striatum with processing of affective stimuli in the named cortical regions support the hypothesis that dopamine transmission in functional divisions of the striatum modulates processing of affective stimuli in specific cortical areas.

    Changes in biogenic amine formation and nitrite depletion in meat batters as affected by pressure-temperature combinations (300 MPa/30 min/7, 20, and 40 degrees C), cooking process (70 degrees C/30 min), and storage (54 days/2 degrees C) were studied. Changes in residual nitrite concentration in raw meat batters were conditioned by the temperature and not by the pressure applied. Cooking process decreased (P nitrite concentration in all samples. High-pressure processing and cooking treatment increased (P nitrite concentration decreased with pressure processing, no effect was observed with the heating process of meat batters. High-pressure processing conditions had no effect on the rate of residual nitrite loss throughout the storage. The application of high pressure decreased (P processing conditions, generally, throughout storage biogenic amine levels did not change or increased, although quantitatively this effect was not very important.

  7. Adult Age Differences in Dual Information Processes: Implications for the Role of Affective and Deliberative Processes in Older Adults' Decision Making.

    Age differences in affective/experiential and deliberative processes have important theoretical implications for judgment and decision theory and important pragmatic implications for older-adult decision making. Age-related declines in the efficiency of deliberative processes predict poorer-quality decisions as we age. However, age-related adaptive processes, including motivated selectivity in the use of deliberative capacity, an increased focus on emotional goals, and greater experience, predict better or worse decisions for older adults depending on the situation. The aim of the current review is to examine adult age differences in affective and deliberative information processes in order to understand their potential impact on judgments and decisions. We review evidence for the role of these dual processes in judgment and decision making and then review two representative life-span perspectives (based on aging-related changes to cognitive or motivational processes) on the interplay between these processes. We present relevant predictions for older-adult decisions and make note of contradictions and gaps that currently exist in the literature. Finally, we review the sparse evidence about age differences in decision making and how theories and findings regarding dual processes could be applied to decision theory and decision aiding. In particular, we focus on prospect theory (Kahneman & Tversky, 1979) and how prospect theory and theories regarding age differences in information processing can inform one another. © 2007 Association for Psychological Science.

    2000-06-01

    Full Text Available The research work done by the author investigates a phenomenological field—the subjective experience of chronic illness and disability—by means of a specific research instrument, the autobiographical narrative interview. It focuses on the concept of narrative identity and its empirical substrate in the scientifically generated texts. Narrative identity is regarded as a situated, pragmatic, autoepistemic and interactive activity drawing on culturally transmitted narrative conventions which is performed within the research context. We have been working with a systematic analytic approach which covers interactive and contextual aspects of the interview situation as well as rhetoric and positioning strategies in the act of telling. Other research questions concern the concept of "narrative coping" and the comparison of partner's narratives on problems of illness and disability, especially on scrutinizing aspects of identity and alterity (self and other in the texts. This work can be understood as combining aspects of the research domains of narratology, identity and coping on the background of a qualitative methodology. URN: urn:nbn:de:0114-fqs0002189

    Instability of affects and interpersonal relations are important features of borderline personality disorder (BPD). Interpersonal problems of individuals suffering from BPD might develop based on abnormalities in the processing of facial affects and high sensitivity to negative affective expressions. The aims of the present study were to examine automatic evaluative shifts and latencies as a function of masked facial affects in patients with BPD compared to healthy individuals. As BPD comorbidity rates for mental and personality disorders are high, we investigated also the relationships of affective processing characteristics with specific borderline symptoms and comorbidity. Twenty-nine women with BPD and 38 healthy women participated in the study. The majority of patients suffered from additional Axis I disorders and/or additional personality disorders. In the priming experiment, angry, happy, neutral, or no facial expression was briefly presented (for 33 ms) and masked by neutral faces that had to be evaluated. Evaluative decisions and response latencies were registered. Borderline-typical symptomatology was assessed with the Borderline Symptom List. In the total sample, valence-congruent evaluative shifts and delays of evaluative decision due to facial affect were observed. No between-group differences were obtained for evaluative decisions and latencies. The presence of comorbid anxiety disorders was found to be positively correlated with evaluative shifting owing to masked happy primes, regardless of baseline-neutral or no facial expression condition. The presence of comorbid depressive disorder, paranoid personality disorder, and symptoms of social isolation and self-aggression were significantly correlated with response delay due to masked angry faces, regardless of baseline. In the present affective priming study, no abnormalities in the automatic recognition and processing of facial affects were observed in BPD patients compared to healthy individuals

  10. Narrative Time and the Thyroid: Hormone Secretions and Storytelling in Italo Svevo's "Doctor Menghi's Drug"

    Directory of Open Access Journals (Sweden)

    Elena Fratto

    2016-12-01

    Full Text Available In the wake of fin-de-siècle discoveries in the field of endocrinology, bodily glands and the hormones they produced featured prominently in the literary works, visual arts, and popular culture of early twentieth-century Europe. Experimental surgery promised rejuvenation and intellectual vitality through gland transplantation and grafting, while phenomena of all sorts began to be associated to hormone production in causal links—from bodily rhythms to behavioral patterns, from the pace of history to the trajectory of nations. Italo Svevo was fascinated by Basedow and Graves’s discoveries on the thyroid, a gland that was supposed to determine the speed and promptness of one’s body according to the amount of hormones it produced—hypothyroidism, or scarcity of hormones, would entail lethargic behavior and slow movements, while hyperthyroidism, or the abundant production of hormones, would lead to excessive activity and consumption. Through the analysis of an early short story by Svevo, “Doctor Menghi’s Drug” (ca. 1904, this paper addresses how the activity of the thyroid affects not only bodily rhythms, but also narrative time—intended as both the time of the story (diegetic time and the pace of storytelling—and it explores how metabolic processes act as constraints for literary creativity by complicating narrative time and raising questions of narrative agency.

    The present study investigated how maternal HIV and mediating family processes are associated with adolescent distress, substance use, and risky sexual behavior. Mother-adolescent (ages 12-21) dyads (N = 264) were recruited from neighborhoods where the HIV-affected families resided (161 had mothers with HIV). Mediating family processes were youth aggressive conflict style, maternal bonding, maternal role reversal expectations, and overall family functioning. Results of structural equation modeling indicated that youth aggressive conflict resolution style was strongly associated with adolescent distress, substance use, and risky sexual behavior. In HIV-affected families, youth less frequently reported using an aggressive conflict resolution style and more frequently reported positive maternal bonds; their mothers reported less positive family functioning than control families. Finally, maternal distress indirectly affected adolescent distress and risk behavior via youth aggressive conflict resolution style.

  12. Narrative inquiry: Locating Aboriginal epistemology in a relational methodology.

    This methodology utilizes narrative analysis and the elicitation of life stories as understood through dimensions of interaction, continuity, and situation. It is congruent with Aboriginal epistemology formulated by oral narratives through representation, connection, storytelling and art. Needed for culturally competent scholarship is an experience of research whereby inquiry into epiphanies, ritual, routines, metaphors and everyday experience creates a process of reflexive thinking for multiple ways of knowing. Based on the sharing of perspectives, narrative inquiry allows for experimentation into creating new forms of knowledge by contextualizing diabetes from the experience of a researcher overlapped with experiences of participants--a reflective practice in itself. The aim of this paper is to present narrative inquiry as a relational methodology and to analyse critically its appropriateness as an innovative research approach for exploring Aboriginal people's experience living with diabetes. Narrative inquiry represents an alternative culture of research for nursing science to generate understanding and explanation of Aboriginal people's 'diabetic self' stories, and to coax open a window for co-constructing a narrative about diabetes as a chronic illness. The ability to adapt a methodology for use in a cultural context, preserve the perspectives of Aboriginal peoples, maintain the holistic nature of social problems, and value co-participation in respectful ways are strengths of an inquiry partial to a responsive and embodied scholarship.

  13. Conflict and disfluency as aversive signals: context-specific processing adjustments are modulated by affective location associations.

    Context-specific processing adjustments are one signature feature of flexible human action control. However, up to now the precise mechanisms underlying these adjustments are not fully understood. Here it is argued that aversive signals produced by conflict- or disfluency-experience originally motivate such context-specific processing adjustments. We tested whether the efficiency of the aversive conflict signal for control adaptation depends on the affective nature of the context it is presented in. In two experiments, high vs. low proportions of aversive signals (Experiment 1: conflict trials; Experiment 2: disfluent trials) were presented either above or below the screen center. This location manipulation was motivated by existing evidence that verticality is generally associated with affective valence with up being positive and down being negative. From there it was hypothesized that the aversive signals would lose their trigger function for processing adjustments when presented at the lower (i.e., more negative) location. This should then result in a reduced context-specific proportion effect when the high proportion of aversive signals was presented at the lower location. Results fully confirmed the predictions. In both experiments, the location-specific proportion effects were only present when the high proportion of aversive signals occurred at the more positive location above but were reduced (Experiment 1) or even eliminated (Experiment 2) when the high proportion occurred at the more negative location below. This interaction of processing adjustments with affective background contexts can thus be taken as further hint for an affective origin of control adaptations.

    2017-01-01

    The longitudinal study aims to expand what is known about the costs and benefits of narrating stressful experiences by exploring changes in rumination within the narrative process and comparing it to changes in self-reflection. Rumination (e.g., brooding, self-criticism, and negative emotions) and self-reflection were measured in stress narratives of 56 college students. There were several goals: (1) examine changes in narrative rumination and narrative self-reflection over 3 days of writing, (2) examine the relations among the changes in narrative rumination variables and narrative self-reflection and (3) examine how changes in narrative rumination and narrative self-reflection relate to multiple measures of psychological functioning. Overall, individuals increased self-reflection over the 3-day writing task. Individuals who increased ruminative brooding across the 3 days of writing showed lower ego identity development (short term and long term) and self-esteem (short term), while increased self-criticism was positively correlated with identity distress (short term). Implications of the different aspects of narrative rumination, specifically in the context of stressful experiences, are discussed.

    Autobiographical memory is a uniquely human form of memory that integrates individual experiences of self with cultural frames for understanding identities and lives. In this review, we present a theoretical and empirical overview of the sociocultural development of autobiographical memory, detailing the emergence of autobiographical memory during the preschool years and the formation of a life narrative during adolescence. More specifically, we present evidence that individual differences in parental reminiscing style are related to children's developing autobiographical narratives. Parents who structure more elaborated coherent personal narratives with their young children have children who, by the end of the preschool years, provide more detailed and coherent personal narratives, and show a more differentiated and coherent sense of self. Narrative structuring of autobiographical remembering follows a protracted developmental course through adolescence, as individuals develop social cognitive skills for temporal understanding and causal reasoning that allows autobiographical memories to be integrated into an overarching life narrative that defines emerging identity. In addition, adolescents begin to use culturally available canonical biographical forms, life scripts, and master narratives to construct a life story and inform their own autobiographical narrative identity. This process continues to be socially constructed in local interactions; we present exploratory evidence that parents help adolescents structure life narratives during coconstructed reminiscing and that adolescents use parents and families as a source for their own autobiographical content and structure. Ultimately, we argue that autobiography is a critical developmental skill; narrating our personal past connects us to our selves, our families, our communities, and our cultures.

    Background. Nursing process is considered as appropriate method to explain the nursing essence, its scientific bases, technologies and humanist assumptions that encourage critical thinking and creativity, and permits solving problems in professional practice. Objective. To assess the application of nursing process and it's affecting factors in Mekelle Zone Hospitals. Methods. A cross sectional design employing quantitative and qualitative methods was conducted in Mekelle zone hospitals March 2011. Qualitative data was collected from14 head nurses of six hospitals and quantitative was collected from 200 nurses selected by simple random sampling technique from the six hospitals proportional to their size. SPSS version 16.1 and thematic analysis was used for quantitative and qualitative data respectively. Results. Majority 180 (90%) of the respondents have poor knowledge and 99.5% of the respondents have a positive attitude towards the nursing process. All of the respondents said that they did not use the nursing process during provision of care to their patients at the time of the study. Majority (75%) of the respondent said that the nurse to patient ratio was not optimal to apply the nursing process. Conclusion and Recommendation. The nursing process is not yet applied in all of the six hospitals. The finding revealed that the knowledge of nurses on the nursing process is not adequate to put it in to practice and high patient nurse ratio affects its application. The studied hospitals should consider the application of the nursing process critically by motivating nurses and monitor and evaluate its progress. PMID:24649360

    Testing narrative engagement theory, this study examines student engagement and teachers’ spontaneous narratives told in a narrative-based drug prevention curriculum. The study describes the extent to which teachers share their own narratives in a narrative-based curriculum, identifies dominant narrative elements, forms and functions, and assesses the relationships among teacher narratives, overall lesson narrative quality, and student engagement. One hundred videotaped lessons of the keepin’ it REAL drug prevention curriculum were coded and the results supported the claim that increased narrative quality of a prevention lesson would be associated with increased student engagement. The quality of narrativity, however, varied widely. Implications of these results for narrative-based prevention interventions and narrative pedagogy are discussed. PMID:26690668
