The primary structure of stanniocalcin (STC), the principal product of the corpuscles of Stannius (CS) in ray-finned fishes, was deduced from STC cDNA clones for two species of holostean, the gar, Lepisosteus osseus and the bowfin, Amia calva. Overlapping partial cDNA clones were amplified by polymerase chain reaction (PCR) from single-strand cDNA of the CS. Excluding the poly(A) tail, the cDNAs of 1863 base pairs [bp] (gar) and 914 bp (bowfin) contained the 5' untranslated region followed by the coding region and the 3' untranslated region. Both the gar and bowfin STC cDNA encode a prehormone of 252 amino acids (aa) with a signal peptide of 32 aa and a mature protein of 220 aa. The deduced aa sequence of gar STC shows 87% identity with bowfin STC, 60-72% identity with most vertebrate STCs and 26% identity with mouse STC2. Phylogenetic analysis of the sequences support a view that the gar and bowfin form a monophyletic holostean clade. RT-PCR revealed in the gar and bowfin that, just as in mammals and rainbow trout, the expression of STC mRNA is widely spread in many tissues and organs. Since the gar and bowfin are representatives of the most ancient fishes known to possess CS, the corpuscular-derived STC molecule in fish has had a conserved evolution.

The emergence, structure and development of ethnic identity during childhood: the case of Roma identity.

Pnevmatikos, Dimitris; Geka, Maria; Divane, Maria

2010-12-01

This study investigates the emergence, development and structure of ethnic identity during childhood. Forty Roma children living in Greece aged between 2.8 and 11.9 years answered questions about their awareness/recognition of four aspects of their ethnic identity-namely place of habitation, traditional costumes, the Roma language, and early betrothal of children-their identity and their sense of stability and constancy. The study also investigates how the children feel about the abandonment of those four aspects. The evidence from the current data supports the hypothesis that awareness of ethnic identity emerges before the age of 4. Moreover, this study offers direct empirical evidence of the multidimensionality of ethnic identity. A model of three concentric rings is proposed, extending from a core containing the most highly valued aspects of ethnic identity to the outer annulus that comprises the nonpermanent and nonstable aspects of ethnic identity. The aspects in each annulus differ in terms of the development of the sense of stability and constancy and the feelings associated with loss of the aspects in question. Even the youngest participants considered the aspects in the core to be stable and constant as well as emotionally charged; and even the 11-year-olds did not consider the aspects contained in the outer, more fluid annulus as stable and constant aspects of their ethnic identity. The development of an aspect is determined by what the majority of adults in a society, at a particular time in history, consider to be most important.

Do pedophiles have a weaker identity structure compared with nonsexual offenders?

PubMed

Tardi, M; Van Gijseghem, H

2001-10-01

The aim of this study was to determine whether pedophiles have a weaker identity structure compared with nonsexual offenders. The recruitment process secured the participation of 87 male adult subjects, divided into three groups: 27 pedophiles who abused male victims (X = 38.6 years), 30 pedophiles who abused female victims (X = 35.5 years), 30 nonsexual offenders (X = 29.8 years). The concept of identity was examined on the basis of two factors: body image limits and ego identity. Two objective tests, the Minnesota Multiphasic Personality Inventory (MMPI) and the Ego Identity Scale, and one projective test, the Rorschach scored according to the Fisher and Cleveland method, were used. A multivariate analysis of covariance, at a significance threshold of p < .05, indicated that pedophiles who abused female victims and pedophiles who abused male victims have more fragile body image limits, as measured by the penetration score, and present a higher level of social introversion (Si scale) than do nonsexual offenders. Moreover, pedophiles who abused male victims have a weaker ego (Es scale) than do pedophiles who abused female victims and nonsexual offenders. In other respects, no significant intergroup difference emerged in terms of body image limits as measured by the barrier score and of strength of ego identity (Ego Identity Scale). Conceptual and empirical elements related to body image and ego identity are addressed to shed light on the potential disturbances in the identity of pedophile subjects. These results imply not only that certain impairments exist at the level of the basis structures of the personality, but also that these impairments should be taken into account in formulating a program and devising a therapeutic process for pedophiles.

Ethnic identity: Factor structure and measurement invariance across ethnic groups.

Feitosa, Jennifer; Lacerenza, Christina N; Joseph, Dana L; Salas, Eduardo

2017-09-01

Considering a historically diversified (and growing) population in the United States, one's ethnic identification is often an important psychological-as well as social and political-construct because it can serve as a hindrance to interpersonal interaction. Despite the importance of ethnic identity in psychological research, the most widely developed ethnic identity measurement tool, the Multigroup Ethnic Identity Measure (MEIM; Phinney, 1992), lacks consensus regarding its psychometric properties. The purpose of this article is to identify the factor structure of this measure and identify whether it exhibits measurement equivalence/invariance (ME/I) across ethnicities. The current findings offer several contributions to the state of the literature. First, our data suggests a two-factor model, including affirmation/commitment and exploration factors, is the most appropriate structure when considering fit and parsimony indices via confirmatory factor analysis. Second, configural and metric measurement equivalence was found across Caucasian and non-Caucasian participants. Interestingly, partial scalar invariance was established when comparing Caucasians with the minority groups with the exception of the Hispanic subgroup, which exhibited no scalar invariance. Third, differences in ethnic identity factor means were found, especially across Caucasians and African Americans. In conclusion, the use of the two-factor model of the MEIM is recommended, and results suggest that the MEIM is an appropriate measure of ethnic identity in most ethnic groups. Limitations and future research are also discussed. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

Background: Adolescence denotes a time in which youth begins to experience dangerous behaviors like substance use and delinquency. Objectives: In this study, we investigated the family power structure and identity style in delinquent and non-delinquent juveniles residing in Tehran, Iran. Materials and Methods: To accomplish the goal of the study, 80 adolescent delinquents of the correction and rehabilitation centers aged between 15 and 18 years were selected with convenience sampling method and 80 students of secondary school age between 15 and 18 years in Tehran, Iran in 2012. They answered the instrument of family power structure (Saidian, 2004) and identity style (ISI-6G: White et al. 1998). The obtained data were analyzed using the independent t-test, chi-square test, and Levene’s test. Results: The findings indicated a significant difference between delinquent and non-delinquent juveniles with regard to family power structure, its subscales (P < 0.001), and identity style (P < 0.001). Moreover, the informational identity style was associated with lower levels of delinquency. In addition, a diffuse-evident identity style was related to the delinquency. Conclusions: These results emphasize that the inappropriate decision-making process pattern in a family has a significant effect on deviant behavior and identity style in adolescents. So, family power structure can be considered in therapeutic interventions (prevention and treatment) for adolescent delinquency. PMID:26834795

To identify the extent of nurse prescription and determine specific medications and/or health-care supplies routinely prescribed by primary care nurses in Spain in a changing legal context. To explore nurse perceptions of legalized nurse prescription’s relationship to professional identity. Although the Spanish public has similar confidence in nurses and physicians, professional identity remains a concern for nurses. Nurse prescription has a confusing history in Spain but is increasingly common elsewhere, and may enhance nursing’s professional profile. A cross-sectional survey reporting the occurrence of nurse prescription in one province in Spain and primary care nurses’ perceptions of nurse prescription and professional identity in this province. The response rate was 69.6% (87 nurses). Frequent nurse-prescribed medications were vaccinations (63.1%), topical antiseptics (60.7%) and antipyretics(44.8%); health-care supplies included supplies for diabetes (51.8%), wound care dressings (44.2%) and incontinence (26.7%). Respondents indicated that nurse prescription positively contributes to the profession and to its development.Conclusion Nurse prescribing exists in primary care in Spain, and formal legalization is in progress but awaits a consensus formulary. Nurses indicated that full legalization would increase professional autonomy and contribute positively to the profession, as an example of how policy can have an impact on practice.Implications for nursing management Spain’s experience with inconclusive shifts in the legal status of nurse prescribing may contribute to the discussion in countries where this professional practice is not yet established.

Primary structure of Lep d I, the main Lepidoglyphus destructor allergen.

1994-10-01

The most relevant allergen of the storage mite Lepidoglyphus destructor (Lep d I) has been characterized. Lep d I is a monomer protein of 13273 Da. The primary structure of Lep d I was determined by N-terminal Edman degradation and partially confirmed by cDNA sequencing. Sequence polymorphism was observed at six positions, with non-conservative substitutions in three of them. No potential N-glycosylation site was revealed by peptide sequencing. The 125-residue sequence of Lep d I shows approximately 40% identity (including the six cysteines) with the overlapping regions of group II allergens from the genus Dermatophagoides, which, however, do not share common allergenic epitopes with Lep d I.

Identity appropriateness and the structure of the theory of planned behaviour.

PubMed

Case, Philippa; Sparks, Paul; Pavey, Louisa

2016-03-01

In contrast to the cost-benefit, utility-based approach to decision-making implicit in models such as the theory of planned behaviour (TPB), the logic of appropriateness (March, 1994. A Primer on Decision Making: How decisions happen. New York, NY: The Free Press) describes decision-making in terms of heuristic decision rules that involve matching identities to situations. This research is the first to apply the logic of appropriateness in conjunction with the theoretical structure of the TPB and assessed whether a measure of identity appropriateness might independently predict adults' intentions to engage in binge drinking. In Study 1, participants (N = 197) completed questionnaires assessing attitudes, subjective norm, perceived behavioural control, past behaviour, and identity appropriateness in relation to binge drinking. Path analysis revealed an independent predictive effect of identity appropriateness on intentions in addition to an indirect effect via attitudes. In Study 2 (N = 179), a prospective measure of behaviour was included in a similar study: Identity appropriateness again predicted intentions independently of the extended TPB predictors. It was again also found to be a strong predictor of attitudes. We suggest that the notion of identity appropriateness may assist in explaining the capacity of measures of self-identity to predict people's behavioural intentions. © 2015 The British Psychological Society.

Individual identity and organisational control: empowerment and modernisation in a primary care trust.

PubMed

McDonald, Ruth

2004-11-01

The notion of empowerment has been increasingly used within management discourses in recent years. Enthusiastic supporters conceive it as an acknowledgement of the individual employee as a talented, creative being, and hence a productive resource for contributing to organisational goals. Alternatively, more critical commentators have interpreted it as another means of exercising control over employees and their identities. Although various commentators have speculated on the management of identity as a means of organizational control, there is very little empirical work from which to draw conclusions. This paper, using participant observation and interview data, represents a contribution to the small body of empirical research in the area. It focuses on an initiative aimed ostensibly at 'empowering' staff in an English Primary Care Trust, which may be seen as an attempt at increasing organisational control by shaping employee identities. As such, these processes can be understood more readily in terms of ethics rather than empowerment. The term ethics is used here in a Foucauldian sense and is linked to the processes of self-definition and self-constraint by which individuals train themselves to become ethical persons. The paper suggests that the outcome of attempts to manufacture particular forms of subjectivity by such methods as 'empowerment' programmes may be very different from those intended.

MAVEN Mission Primary Structure Complete

2017-12-08

NASA's Mars Atmosphere and Volatile EvolutioN (MAVEN) mission has reached a new milestone. Lockheed Martin has completed building the primary structure of the MAVEN spacecraft at its Space Systems Company facility near Denver. The MAVEN spacecraft is scheduled to launch in November 2013 and will be the first mission devoted to understanding the Martian upper atmosphere. The mission's principal investigator is Bruce Jakosky from the Laboratory for Atmospheric and Space Physics at the University of Colorado. In the photo taken on Sept. 8, technicians from Lockheed Martin are inspecting the MAVEN primary structure following its recent completion at the company’s Composites Lab. The primary structure is cube shaped at 7.5 feet x 7.5 feet x 6.5 feet high (2.3 meters x 2.3 meters x 2 meters high). Built out of composite panels comprised of aluminum honeycomb sandwiched between graphite composite face sheets and attached to one another with metal fittings, the entire structure only weighs 275 pounds (125 kilograms). At the center of the structure is the 4.25 feet (1.3 meters) diameter core cylinder that encloses the hydrazine propellant tank and serves as the primary vertical load-bearing structure. The large tank will hold approximately 3,615 pounds (1640 kilograms) of fuel.

Induced pluripotent stem cell (iPSC)-derived cortical neurons potentially present a powerful new model to understand corticogenesis and neurological disease. Previous work has established that differentiation protocols can produce cortical neurons, but little has been done to characterize these at cellular resolution. In particular, it is unclear to what extent in vitro two-dimensional, relatively disordered culture conditions recapitulate the development of in vivo cortical layer identity. Single-cell multiplex reverse transcriptase-quantitative polymerase chain reaction (RT-qPCR) was used to interrogate the expression of genes previously implicated in cortical layer or phenotypic identity in individual cells. Totally, 93.6% of single cells derived from iPSCs expressed genes indicative of neuronal identity. High proportions of single neurons derived from iPSCs expressed glutamatergic receptors and synaptic genes. And, 68.4% of iPSC-derived neurons expressing at least one layer marker could be assigned to a laminar identity using canonical cortical layer marker genes. We compared single-cell RNA-seq of our iPSC-derived neurons to available single-cell RNA-seq data from human fetal and adult brain and found that iPSC-derived cortical neurons closely resembled primary fetal brain cells. Unexpectedly, a subpopulation of iPSC-derived neurons co-expressed canonical fetal deep and upper cortical layer markers. However, this appeared to be concordant with data from primary cells. Our results therefore provide reassurance that iPSC-derived cortical neurons are highly similar to primary cortical neurons at the level of single cells but suggest that current layer markers, although effective, may not be able to disambiguate cortical layer identity in all cells.

Mycorrhizal fungal growth responds to soil characteristics, but not host plant identity, during a primary lacustrine dune succession.

PubMed

Sikes, Benjamin A; Maherali, Hafiz; Klironomos, John N

2014-04-01

Soil factors and host plant identity can both affect the growth and functioning of mycorrhizal fungi. Both components change during primary succession, but it is unknown if their relative importance to mycorrhizas also changes. This research tested how soil type and host plant differences among primary successional stages determine the growth and plant effects of arbuscular mycorrhizal (AM) fungal communities. Mycorrhizal fungal community, plant identity, and soil conditions were manipulated among three stages of a lacustrine sand dune successional series in a fully factorial greenhouse experiment. Late succession AM fungi produced more arbuscules and soil hyphae when grown in late succession soils, although the community was from the same narrow phylogenetic group as those in intermediate succession. AM fungal growth did not differ between host species, and plant growth was similarly unaffected by different AM fungal communities. These results indicate that though ecological filtering and/or adaptation of AM fungi occurs during this primary dune succession, it more strongly reflects matching between fungi and soils, rather than interactions between fungi and host plants. Thus, AM fungal performance during this succession may not depend directly on the sequence of plant community succession.

The structure of the perceived professional identity of Japanese public health nurses.

2018-05-01

As health problems become more diverse and complicated, the way public health nurses (PHNs) work is changing. Research at the conceptual level of professional identity of PHNs is lacking. This study aimed to explore the structure of the perceived professional identity of Japanese PHNs. Grounded theory method was used. Twenty-five PHNs in Japanese municipalities were participated in the study. Data were collected through semistructured interviews and analyzed using open, axial, and selective coding. Three categories emerged: (1) providing support to the consulter directly, (2) working as a member of the administrative organization, and (3) working for all residents to improve community development. The modality of perceived professional identity showed interindividual and intraindividual differences and was either stable or unstable. The perceived professional identities coexisted, but there was a conflict between (1) and (2). PHNs should be made aware of the three identities revealed in our study and the possibility of a conflict between identities. Moreover, to ensure working for all residents to improve community development, a population-based approach to education is needed with cooperation of universities and clinical practice. © 2018 Wiley Periodicals, Inc.

The phallic castration complex and primary femininity: paired developmental lines toward female gender identity.

PubMed

Mayer, E L

1995-01-01

I suggest that two developmental lines contribute to the achievement of female gender identity. One is rooted in the phallic castration complex, and the other in primary femininity. Far from being mutually exclusive, the two comprise necessary aspects of every girl's progress toward becoming a woman. To that extent, every woman's analysis will include the analysis of compromise formations that emerge from both. In distinguishing clinical manifestations of each developmental line, I suggest that it may be useful to conceptualize primary femininity and the phallic castration complex as affect-defense configurations which incorporate two fundamentally different ideas about danger. In conflicts of primary femininity, danger is anticipated: anxiety is the signal for compromise formation, since what is actually possessed (the female genital) is valued and is therefore imagined as subject to danger. In the phallic castration complex, danger is imagined already to have occurred. Depressive affect becomes the primary motive for defense, based on a fantasy that what is valued (the male genital) has already been lost. This distinction may facilitate our efforts to specify exactly how recent revisions in theories of female development have explicit implications for practice.

1992-01-01

The goal of the NASA Advanced Composites Technology (ACT) Program is to provide the technology required to gain the full benefit of weight savings and performance offered by composite primary structures. Achieving the goal is dependent on developing composite materials and structures which are damage tolerant and economical to manufacture. Researchers at NASA LaRC and Douglas Aircraft Company are investigating stitching reinforcement combined with resin transfer molding (RTM) to create structures meeting the ACT program goals. The Douglas work is being performed under a NASA contract entitled Innovative Composites Aircraft Primary Structures (ICAPS). The research is aimed at materials, processes and structural concepts for application in both transport wings and fuselages. Empirical guidelines are being established for stitching reinforcement in primary structures. New data are presented in this paper for evaluation tests of thick (90-ply) and thin (16-ply) stitched laminates, and from selection tests of RTM composite resins. Tension strength, compression strength and post-impact compression strength data are reported. Elements of a NASA LaRC program to expand the science base for stitched/RTM composites are discussed.

Sibling differentiation, identity development, and the lateral dimension of psychic life.

PubMed

Vivona, Jeanine M

2007-01-01

The lateral dimension of psychic life, lived through relationships with siblings and their substitutes, is structured around a distinct psychic challenge: to find one's unique place in a world of similar others. Like the challenge that structures the vertical parent-child dimension, the lateral challenge is fraught with conflict and ambivalence; its resolution imbues psychic structure. That resolution may be accomplished through a process of differentiation, an active and unconscious process of identity development by which a child amplifies differences with siblings and minimizes similarities. Differentiation from siblings serves to mitigate interpersonal rivalry with them and to ease internal conflict associated with the lateral dimension. Three clinical examples are offered to illustrate the operation of sibling differentiation and its costs, particularly in terms of constricted identity and attenuated relationships with siblings and peers. Differentiation as a process of becoming what the other is not has been eclipsed by identification in psychoanalytic theories of identity development. Yet differentiation is a common strategy for resolving the primary rivalries and conflicts of the lateral dimension, and has unique developmental and clinical implications.

Medical students develop professional identity through structured activities and impromptu interactions in various settings. We explored if contributing to an Objective Structured Teaching Exercise (OSTE) influenced students' professional identity development. University clinical faculty members participated in a faculty development program on clinical supervision. Medical students who participated in OSTEs as simulated residents were interviewed in focus groups about what they learnt from the experience and how the experience influenced their vision of learning and teaching. Transcripts were analyzed using the Goldie's personality and social structure perspective model. Twenty-five medical students out of 32 students involved in OSTEs participated. On an institutional level, students developed a feeling of belonging to the institution. At an interactional level, students realized they could influence the teaching interaction by actively seeking or giving feedback. On the personal level, students realized that errors could become sources of learning and felt better prepared to receive faculty feedback. Taking part in OSTEs as a simulated resident has a positive impact on students' vision regarding the institution as a learning environment and their own role by actively seeking or giving feedback. OSTEs support their professional identity development regarding learning and teaching while sustaining faculty development.

Identity as a 'patchwork': aspects of identity among low-income Brazilian travestis.

PubMed

Garcia, Marcos Roberto Vieira

2009-08-01

This paper is based on findings from a qualitative study that took place within the context of a four-year healthcare programme directed towards low-income travestis in the central area of Sao Paulo, Brazil. Throughout the study the formation of social identity among travestis was investigated through a focus on four axes: gender, body, work and violence. This paper subjects the identity of the travestis to a critical analysis and proposes a view of their sense of self as a 'patchwork' assembled through the assimilation of various fragments of identity common in Brazilian society. The primary identities assimilated by the travestis under study were, in the area of femininity, the submissive woman, the puta ['whore'] and the super-seductive woman and, in the area of masculinity, the viado ['queer'], the malandro ['rascal'] and the bandido ['bandit']. The resulting travesti identity exhibited not only gender ambiguity, but also contradictions among the feminine identities described, as well as among the masculine ones.

The structure of ethnic attitudes: the effects of target group, region, gender, and national identity.

Verkuyten, M

1997-08-01

The present study was an assessment of attitudes of 410 ethnically Dutch adolescents toward three ethnic minority groups living in the Netherlands. Stereotypes, symbolic beliefs, affective associations, and the evaluation of possible interactions were used to predict the global evaluation of ethnic outgroups and accounted for much of the variance in ethnic attitudes. The relative importance of the four predictors varied by target group and location. Gender differences were found in the structure of attitudes; symbolic beliefs played a greater role in the attitudes of boys, whereas emotions played a more central role in the attitudes of girls. The evaluation of Dutch identity was related to the favorability of ethnic attitudes and also to the underlying structure. Respondents with a positive national identity had less favorable ethnic attitudes, and emotions were more predictive of their attitudes, whereas symbolic beliefs were most predictive among respondents with a less positive national identity.

Metabolism of gonadotropins: comparisons of the primary structures of the human pituitary and urinary LH beta cores and the chimpanzee CG beta core demonstrate universality of core production.

PubMed

Birken, S; Gawinowicz, M A; Maydelman, Y; Milgrom, Y

2001-10-01

The gonadotropins are a family of closely related heterodimeric glycoprotein hormones homologous in structure to disulfide-knot growth factors. Metabolic proteolytic processing in vivo of this disulfide cross-linked region results in urinary excretion of a residual highly stable core structure. The primary structure of the pituitary form of the hLH beta core was reported earlier, but it has proved difficult to isolate the urinary core, although antibodies to the pituitary core demonstrated its presence. By conventional and immunoaffinity methods, the urinary core has been isolated and its structure determined by both chemical and mass spectrometric methods. The urinary hLH beta core is the same as the pituitary-extracted hLH beta core, beta 6-40 disulfide bridged to beta 55-93, except that the pituitary core is more heterogeneous containing also beta 49-93. These findings imply a dual origin of urinary cores, both directly from a secreting tissue and by kidney processing of circulating hormone. We also found that pregnant chimpanzees excrete a CG beta core with a primary structure identical to that of the human CG beta core of pregnancy. In conclusion, gonadotropin core generation and urinary excretion of nearly identical gonadotropin metabolites is common among primates. Although possible biological functions of these core fragments remain unproven, they have diagnostic utility because of their stability and abundance.

Fitting identity in the reasoned action framework: A meta-analysis and model comparison.

PubMed

Paquin, Ryan S; Keating, David M

2017-01-01

Several competing models have been put forth regarding the role of identity in the reasoned action framework. The standard model proposes that identity is a background variable. Under a typical augmented model, identity is treated as an additional direct predictor of intention and behavior. Alternatively, it has been proposed that identity measures are inadvertent indicators of an underlying intention factor (e.g., a manifest-intention model). In order to test these competing hypotheses, we used data from 73 independent studies (total N = 23,917) to conduct a series of meta-analytic structural equation models. We also tested for moderation effects based on whether there was a match between identity constructs and the target behaviors examined (e.g., if the study examined a "smoker identity" and "smoking behavior," there would be a match; if the study examined a "health conscious identity" and "smoking behavior," there would not be a match). Average effects among primary reasoned action variables were all substantial, rs = .37-.69. Results gave evidence for the manifest-intention model over the other explanations, and a moderation effect by identity-behavior matching.

Advanced composite structural concepts and material technologies for primary aircraft structures

NASA Technical Reports Server (NTRS)

Jackson, Anthony

1991-01-01

Structural weight savings using advanced composites have been demonstrated for many years. Most military aircraft today use these materials extensively and Europe has taken the lead in their use in commercial aircraft primary structures. A major inhibiter to the use of advanced composites in the United States is cost. Material costs are high and will remain high relative to aluminum. The key therefore lies in the significant reduction in fabrication and assembly costs. The largest cost in most structures today is assembly. As part of the NASA Advanced Composite Technology Program, Lockheed Aeronautical Systems Company has a contract to explore and develop advanced structural and manufacturing concepts using advanced composites for transport aircraft. Wing and fuselage concepts and related trade studies are discussed. These concepts are intended to lower cost and weight through the use of innovative material forms, processes, structural configurations and minimization of parts. The approach to the trade studies and the downselect to the primary wing and fuselage concepts is detailed. The expectations for the development of these concepts is reviewed.

Transforming physics educator identities: TAs help TAs become teaching professionals

NASA Astrophysics Data System (ADS)

Gretton, Anneke L.; Bridges, Terry; Fraser, James M.

2017-05-01

Research-based instructional strategies have been shown to dramatically improve student learning, but widespread adoption of these pedagogies remains limited. Post-secondary teaching assistants (TAs), with their current positions in course delivery and future roles as academic leaders, are an essential target group for teacher training. However, the literature suggests that successful TA professional development must address not only pedagogical practices but also the cultivation of physics educator identity. The primary goal of this study is to build a framework for TA professional development that strengthens the TA's identity as a physics educator. We base this framework on Etienne Wenger's model for communities of practice and Côté and Levine's personality and social structure identity perspective. We explore this framework in the context of a 12-week, low-cost, TA-led and TA-centered professional development intervention. Our qualitative and quantitative data suggest that this efficient community-based intervention strengthened TAs' identification as physics educators.

Factor Structure of a Multidimensional Gender Identity Scale in a Sample of Chinese Elementary School Children

Yu, Lu; Xie, Dong; Shek, Daniel T. L.

2012-01-01

This study examined the factor structure of a scale based on the four-dimensional gender identity model (Egan and Perry, 2001) in 726 Chinese elementary school students. Exploratory factor analyses suggested a three-factor model, two of which corresponded to “Felt Pressure” and “Intergroup Bias” in the original model. The third factor “Gender Compatibility” appeared to be a combination of “Gender Typicality” and “Gender Contentment” in the original model. Follow-up confirmatory factor analysis (CFA) indicated that, relative to the initial four-factor structure, the three-factor model fits the current Chinese sample better. These results are discussed in light of cross-cultural similarities and differences in development of gender identity. PMID:22701363

Identity theory and personality theory: mutual relevance.

Stryker, Sheldon

2007-12-01

Some personality psychologists have found a structural symbolic interactionist frame and identity theory relevant to their work. This frame and theory, developed in sociology, are first reviewed. Emphasized in the review are a multiple identity conception of self, identities as internalized expectations derived from roles embedded in organized networks of social interaction, and a view of social structures as facilitators in bringing people into networks or constraints in keeping them out, subsequently, attention turns to a discussion of the mutual relevance of structural symbolic interactionism/identity theory and personality theory, looking to extensions of the current literature on these topics.

Governing the ethical consumer: identity, choice and the primary care medical encounter.

PubMed

McDonald, Ruth; Mead, Nicola; Cheraghi-Sohi, Sudeh; Bower, Peter; Whalley, Diane; Roland, Martin

2007-04-01

Government policy promoting consumerism in healthcare can be seen as offering up certain preferred identities to which its citizens are encouraged to aspire. Whilst many commentators reject the notion that health services users should be conceived of as consumers, this paper outlines the relevance of the concept to our understanding of the ways in which individuals manage their health and service use. The paper examines the identity work undertaken by individuals in relation to decisions about healthcare preferences and assesses the extent to which this is compatible with the identities promoted in Government policy. We suggest that in circumstances where individuals feel both a sense of personal entitlement and a desire to be supportive of the needs of other members of the community, 'doing' ethical consumer can be fraught with discomfort and anxiety. These anxieties are exacerbated in a context where citizenship is increasingly being defined in terms of consumer identities, and making good (health) choices might be seen as distinguishing the civilised from the marginalised.

Social identity and cooperation in cultural evolution.

PubMed

Smaldino, Paul E

2017-12-06

I discuss the function of social identity signaling in facilitating cooperative group formation, and how the nature of that function changes with the structure of social organization. I propose that signals of social identity facilitate assortment for successful coordination in large-scale societies, and that the multidimensional, context-dependent nature of social identity is crucial for successful coordination when individuals have to cooperate in different contexts. Furthermore, the structure of social identity is tied to the structure of society, so that as societies grow larger and more interconnected, the landscape of social identities grows more heterogeneous. This discussion bears directly on the need to articulate the dynamics of emergent, ephemeral groups as a major factor in human cultural evolution. Copyright © 2017 The Author.

Structural health monitoring and impact detection for primary aircraft structures

NASA Astrophysics Data System (ADS)

Kosters, Eric; van Els, Thomas J.

2010-04-01

The increasing use of thermoplastic carbon fiber-reinforced plastic (CFRP) materials in the aerospace industry for primary aircraft structures, such as wing leading-edge surfaces and fuselage sections, has led to rapid growth in the field of structural health monitoring (SHM). Impact, vibration, and load can all cause failure, such as delamination and matrix cracking, in composite materials. Moreover, the internal material damage can occur without being visible to the human eye, making inspection of and clear insight into structural integrity difficult using currently available evaluation methods. Here, we describe the detection of impact and its localization in materials and structures by high-speed interrogation of multiple-fiber Bragg grating (FBG) sensors mounted on a composite aircraft component.

Thioesterases: A new perspective based on their primary and tertiary structures

PubMed Central

Cantu, David C; Chen, Yingfei; Reilly, Peter J

2010-01-01

Thioesterases (TEs) are classified into EC 3.1.2.1 through EC 3.1.2.27 based on their activities on different substrates, with many remaining unclassified (EC 3.1.2.–). Analysis of primary and tertiary structures of known TEs casts a new light on this enzyme group. We used strong primary sequence conservation based on experimentally proved proteins as the main criterion, followed by verification with tertiary structure superpositions, mechanisms, and catalytic residue positions, to accurately define TE families. At present, TEs fall into 23 families almost completely unrelated to each other by primary structure. It is assumed that all members of the same family have essentially the same tertiary structure; however, TEs in different families can have markedly different folds and mechanisms. Conversely, the latter sometimes have very similar tertiary structures and catalytic mechanisms despite being only slightly or not at all related by primary structure, indicating that they have common distant ancestors and can be grouped into clans. At present, four clans encompass 12 TE families. The new constantly updated ThYme (Thioester-active enzYmes) database contains TE primary and tertiary structures, classified into families and clans that are different from those currently found in the literature or in other databases. We review all types of TEs, including those cleaving CoA, ACP, glutathione, and other protein molecules, and we discuss their structures, functions, and mechanisms. PMID:20506386

Development of children's identity and position processing for letter, digit, and symbol strings: A cross-sectional study of the primary school years.

PubMed

Schubert, Teresa; Badcock, Nicholas; Kohnen, Saskia

2017-10-01

Letter recognition and digit recognition are critical skills for literate adults, yet few studies have considered the development of these skills in children. We conducted a nine-alternative forced-choice (9AFC) partial report task with strings of letters and digits, with typographical symbols (e.g., $, @) as a control, to investigate the development of identity and position processing in children. This task allows for the delineation of identity processing (as overall accuracy) and position coding (as the proportion of position errors). Our participants were students in Grade 1 to Grade 6, allowing us to track the development of these abilities across the primary school years. Our data suggest that although digit processing and letter processing end up with many similarities in adult readers, the developmental trajectories for identity and position processing for the two character types differ. Symbol processing showed little developmental change in terms of identity or position accuracy. We discuss the implications of our results for theories of identity and position coding: modified receptive field, multiple-route model, and lexical tuning. Despite moderate success for some theories, considerable theoretical work is required to explain the developmental trajectories of letter processing and digit processing, which might not be as closely tied in child readers as they are in adult readers.

Sport-Related Identities and the "Toxic Jock"

PubMed

Miller, Kathleen E

2009-01-01

Little attention has been paid to the multidimensional nature of athletic involvement, which includes identity formation as well as participation in sports activities. Five hundred eighty-one sport-involved undergraduate students completed a questionnaire assessing their sport-related identities, goal orientations, primary sport ratings, and conformity to masculine norms. F-tested mean comparisons and hierarchical linear regressions were used to explore the characteristics associated with two distinct sport-related identities ("athletes" and "jocks"). Jock identity was associated with an ego-oriented approach to sports (men only), whereas athlete identity was associated with a task-oriented approach (both genders). Jock identity was positively associated with conformity to masculine norms, particularly for men, whereas athlete identity was positively associated with some masculine norms (i.e., Winning) and negatively associated with others (i.e., Playboy). These findings help to identify the correlates of a "toxic Jock" identity that may signal elevated risk for health-compromising behavior.

Critical look at physics identity: An operationalized framework for examining race and physics identity

2018-06-01

Studies on physics identity are appearing more frequently and often responding to increased awareness of the underrepresentation of students of color in physics. In our broader research, we focus our efforts on understanding how racial identity and physics identity are negotiated throughout the experiences of Black physicists. In this paper, we present a Critical Physics Identity framework that can be used to examine racialized physics identity and demonstrate the utility of this framework by analyzing interviews with four physicists. Our framework draws from prior constructs of physics identity and racialized identity and provides operational definitions of six interacting dimensions. In this paper, we present the operationalized constructs, demonstrate how we use these constructs to code narrative data, as well as outline three methods of analysis that may be applied to study systems and structures and their influences on the experiences of Black students.

A topological optimization design for the lightweight technology of supporting plate of the primary mirror is presented in this paper. The supporting plate of the primary mirror is topologically optimized under the condition of determined shape, loads and environment. And the optimal structure is obtained. The diameter of the primary mirror in this paper is 450mm, and the material is SiC1 . It is better to select SiC/Al as the supporting material. Six points of axial relative displacement can be used as constraints in optimization2 . Establishing the supporting plate model and setting up the model parameters. After analyzing the force of the main mirror on the supporting plate, the model is applied with force and constraints. Modal analysis and static analysis of supporting plates are calculated. The continuum structure topological optimization mathematical model is created with the variable-density method. The maximum deformation of the surface of supporting plate under the gravity of the mirror and the first model frequency are assigned to response variable, and the entire volume of supporting structure is converted to object function. The structures before and after optimization are analyzed using the finite element method. Results show that the optimized fundamental frequency increases 29.85Hz and has a less displacement compared with the traditional structure.

Burnout is a threat to the primary care workforce. We investigated the relationship between team structure, team culture, and emotional exhaustion of clinicians and staff in primary care practices. We surveyed 231 clinicians and 280 staff members of 10 public and 6 university-run primary care clinics in San Francisco in 2012. Predictor variables included team structure, such as working in a tight teamlet, and perception of team culture. The outcome variable was the Maslach emotional exhaustion scale. Generalized estimation equation models were used to account for clustering at the clinic level. Working in a tight team structure and perceptions of a greater team culture were associated with less clinician exhaustion. Team structure and team culture interacted to predict exhaustion: among clinicians reporting low team culture, team structure seemed to have little effect on exhaustion, whereas among clinicians reporting high team culture, tighter team structure was associated with less exhaustion. Greater team culture was associated with less exhaustion among staff. However, unlike for clinicians, team structure failed to predict exhaustion among staff. Fostering team culture may be an important strategy to protect against exhaustion in primary care and enhance the benefit of tight team structures.

Social Worker Identity: A Profession in Context.

PubMed

Forenza, Brad; Eckert, Caitlin

2018-01-01

Social work is a broad field encompassing micro, mezzo, and macro areas of practice. Consequently, the field lacks a unifying professional identity due to the expansiveness of the profession. Professional identity is conceptualized as an extension of social identity, vis-à-vis the embodiment of three qualities: connectedness, expansiveness, and effectiveness. This study used 12 in-depth, individual interviews with practicing social workers to explore these qualities. Findings from interviews reveal six primary themes and 21 subthemes pertaining to social worker identity. Themes and subthemes are organized according to three broad families (social work in context, professional trajectories, and external influences). Implications for policy, practice, and future research are presented. © 2017 National Association of Social Workers.

Māori identity signatures: A latent profile analysis of the types of Māori identity.

Māori are the indigenous peoples of New Zealand. However, the term 'Māori' can refer to a wide range of people of varying ethnic compositions and cultural identity. We present a statistical model identifying 6 distinct types, or 'Māori Identity Signatures,' and estimate their proportion in the Māori population. The model is tested using a Latent Profile Analysis of a national probability sample of 686 Māori drawn from the New Zealand Attitudes and Values Study. We identify 6 distinct signatures: Traditional Essentialists (22.6%), Traditional Inclusives (16%), High Moderates (31.7%), Low Moderates (18.7%), Spiritually Orientated (4.1%), and Disassociated (6.9%). These distinct Identity Signatures predicted variation in deprivation, age, mixed-ethnic affiliation, and religion. This research presents the first formal statistical model assessing how people's identity as Māori is psychologically structured, documents the relative proportion of these different patterns of structures, and shows that these patterns reliably predict differences in core demographics. We identify a range of patterns of Māori identity far more diverse than has been previously proposed based on qualitative data, and also show that the majority of Māori fit a moderate or traditional identity pattern. The application of our model for studying Māori health and identity development is discussed. (c) 2015 APA, all rights reserved).

Obligatory and facultative brain regions for voice-identity recognition

2018-01-01

Abstract Recognizing the identity of others by their voice is an important skill for social interactions. To date, it remains controversial which parts of the brain are critical structures for this skill. Based on neuroimaging findings, standard models of person-identity recognition suggest that the right temporal lobe is the hub for voice-identity recognition. Neuropsychological case studies, however, reported selective deficits of voice-identity recognition in patients predominantly with right inferior parietal lobe lesions. Here, our aim was to work towards resolving the discrepancy between neuroimaging studies and neuropsychological case studies to find out which brain structures are critical for voice-identity recognition in humans. We performed a voxel-based lesion-behaviour mapping study in a cohort of patients (n = 58) with unilateral focal brain lesions. The study included a comprehensive behavioural test battery on voice-identity recognition of newly learned (voice-name, voice-face association learning) and familiar voices (famous voice recognition) as well as visual (face-identity recognition) and acoustic control tests (vocal-pitch and vocal-timbre discrimination). The study also comprised clinically established tests (neuropsychological assessment, audiometry) and high-resolution structural brain images. The three key findings were: (i) a strong association between voice-identity recognition performance and right posterior/mid temporal and right inferior parietal lobe lesions; (ii) a selective association between right posterior/mid temporal lobe lesions and voice-identity recognition performance when face-identity recognition performance was factored out; and (iii) an association of right inferior parietal lobe lesions with tasks requiring the association between voices and faces but not voices and names. The results imply that the right posterior/mid temporal lobe is an obligatory structure for voice-identity recognition, while the inferior parietal

Roles and identities in transition: boundaries of work and inter-professional relationships at the interface between telehealth and primary care.

PubMed

Segar, Julia; Rogers, Anne; Salisbury, Chris; Thomas, Clare

2013-11-01

Shifting the balance of care towards home and community is viewed as requiring interventions which enhance or complement primary care. Technology-based interventions are seen as key to the future in this work. Telehealthcare implicates a new agenda for inter-professional working across boundaries of healthcare. One such interface is between telehealthcare professionals and professionals located in primary care. This study reports the findings from a qualitative study forming part of a broader project examining the potential of developing and implementing telehealth interventions to support patients with long-term conditions. Semi-structured interviews were undertaken with telehealth nurse care managers, practice nurses and general practitioners in their respective work settings (39 interviews with 62 participants). Observation was undertaken at a telehealth call centre. The research took place between April 2010 and March 2011. Thematic analysis of qualitative data was undertaken. Telehealth nurse care managers' interviews suggested narrative constructions of new roles and identities to fit telehealth work, combining a holistic ideal and retro-appeal with 'traditional' values of nursing, which distinguished and distanced them from counterparts in general practices. Practice nurses and general practitioners were ambivalent and often sceptical about the contribution of telehealth to long-term condition work. Practice nurses' accounts suggested a sense of protectiveness about maintaining boundaries around established remits of managing long-term conditions; general practitioners, having devolved much of the care of long-term conditions to nurses, were keen to retain their positions as gatekeepers to resources. Perceptions of shifts of professional roles, new ways of working and how they are valued form a relevant contextual element to the introduction of telehealth interventions. A pre-emptive view and response to how professionals understand and approach increasingly

Predicting Nurses' Turnover: The Aversive Effects of Decreased Identity, Poor Interpersonal Communication, and Learned Helplessness.

PubMed

Moreland, Jennifer J; Ewoldsen, David R; Albert, Nancy M; Kosicki, Gerald M; Clayton, Margaret F

2015-01-01

Through a social identity theoretical lens, this study examines how nurses' identification with their working small group, unit, or floor, nursing role (e.g., staff ER nurse, nurse practitioner), and nursing profession relate to nurses' interaction involvement, willingness to confront conflict, feelings of learned helplessness, and tenure (employment turnover) intentions. A cross-sectional survey (N = 466) was conducted at a large, quaternary care hospital system. Structural equation modeling uncovered direct and indirect effects between the five primary variables. Findings demonstrate direct relationships between nurse identity (as a latent variable) and interaction involvement, willingness to confront conflict, and tenure intentions. Feelings of learned helplessness are attenuated by increased nurse identity through interaction involvement and willingness to confront conflict. In addition, willingness to confront conflict and learned helplessness mediate the relationship between interaction involvement and nurses' tenure intentions. Theoretical extensions include indirect links between nurse identity and learned helplessness via interaction involvement and willingness to confront conflict. Implications for interpersonal communication theory development, health communication, and the nursing profession are discussed.

Responses to professional identity threat: Identity management strategies in incident narratives of health care professionals.

2015-01-01

The purpose of this paper is to explore sensemaking of incidents by health care professionals through an analysis of the role of professional identity in narratives of incidents. Using insights from social identity theory, the authors argue that incidents may create a threat of professional identity, and that professionals make use of identity management strategies in response to this identity threat. The paper draws on a qualitative analysis of incident narratives in 14 semi-structured interviews with physicians, nurses, and residents at a Dutch specialist hospital. The authors used an existing framework of identity management strategies to categorize the narratives. The analysis yielded two main results. First, nurses and residents employed multiple types of identity management strategies simultaneously, which points to the possible benefit of combining different strategies. Second, physicians used the strategy of patronization of other professional groups, a specific form of downward comparison. The authors discuss the implications of the findings in terms of the impact of identity management strategies on the perpetuation of hierarchical differences in health care. The authors argue that efforts to manage incident handling may profit from considering social identity processes in sensemaking of incidents. This is the first study that systematically explores how health care professionals use identity management strategies to maintain a positive professional identity in the face of incidents. This study contributes to research on interdisciplinary cooperation in health care.

Implication of the cause of differences in 3D structures of proteins with high sequence identity based on analyses of amino acid sequences and 3D structures.

2014-09-18

Proteins that share a high sequence homology while exhibiting drastically different 3D structures are investigated in this study. Recently, artificial proteins related to the sequences of the GA and IgG binding GB domains of human serum albumin have been designed. These artificial proteins, referred to as GA and GB, share 98% amino acid sequence identity but exhibit different 3D structures, namely, a 3α bundle versus a 4β + α structure. Discriminating between their 3D structures based on their amino acid sequences is a very difficult problem. In the present work, in addition to using bioinformatics techniques, an analysis based on inter-residue average distance statistics is used to address this problem. It was hard to distinguish which structure a given sequence would take only with the results of ordinary analyses like BLAST and conservation analyses. However, in addition to these analyses, with the analysis based on the inter-residue average distance statistics and our sequence tendency analysis, we could infer which part would play an important role in its structural formation. The results suggest possible determinants of the different 3D structures for sequences with high sequence identity. The possibility of discriminating between the 3D structures based on the given sequences is also discussed.

Each group or profession has its own discourse. Discourses create identity, support institutions and reproduce power relationships. Professional identity of Iranian nurses, which has recently had the opportunity to represent itself in social arena, needs investigation. This study aimed to make internal aspect of this identity clear. This study was conducted by discourse analysis, using data of 23 semi-structured individual interviews and 4 focus group interviews with nurses and senior nursing students of Tehran and Isfahan University of Medical Sciences, Iran, to evaluate their professional identity. In professional self-concept, elements like spirituality value and low financial benefits were identified as well as conflicting features of holiness and humility, identity emerging, identity escape, low professional self-confidence and justice seeking, lost professional authority and pride. Nursing professional identity has been formed based on cultural social structure, values and beliefs governing health system. This is a spectrum of a growing and emerging identity to a developed but forgotten identity. Although nursing discourse is subordinate in health system discourse, signs of moving toward professional maturity have emerged.

Mechanical Attachment of Reusable Surface Insulation to Space Shuttle Primary Structure

Three methods of attaching surface insulation tiles to shuttle primary structure have been proposed: direct bond, mechanical attachment, and subpanels with standoffs. The direct bond approach is lightweight but is difficult to refurbish and inspect. The subpanel approach is heavier but allows for easy refurbishment since subpanels are easily removed and replaced. The mechanical attachment approach allows easy refurbishment and inspection and is lightweight when an efficient insulator is used between surface insulation tiles and primary structure.

Identity related to living situation in six individuals with congenital quadriplegia.

PubMed

Robey, Kenneth L

2008-01-01

This study was a preliminary examination of structural aspects of identity, particularly identity associated with living situation, in individuals who have quadriplegia due to cerebral palsy. A hierarchical classes algorithm (HICLAS) was used to construct idiographic 'identity structure' models for three individuals who are living in an inpatient hospital setting and for three individuals living in community-based group residences. Indices derived from the models indicate that the identity 'myself as one who has a disability' was structurally superordinate (i.e., resided at a high hierarchical level) for all six participants, suggesting a high level of importance of this identity in participants' sense of self. The models also indicate that while identity associated with one's particular living situation was superordinate for persons living in the hospital, it was not for persons living in community residences. While conclusions based on this small sample are necessarily limited, the data suggest that identity associated with living situation might differ in structural centrality, and presumably subjective importance, for persons living in inpatient versus community-based settings.

In this study, we analyzed the molecular epidemiology of extended-spectrum β-lactamase (ESBL)-producing Proteus mirabilis isolates collected from the central region of Japan. Between 2005 and 2012, 820 clinical P. mirabilis isolates were obtained from ten acute care hospitals in Japan. We characterized ESBL confirmatory test-positive isolates by sequencing the ESBL genes and their flanking regions, detecting plasmid replicons, and performing pulsed-field gel electrophoresis (PFGE). Ninety-six isolates (12%) were positive according to the ESBL confirmatory test; all these isolates possessed bla CTX-M-2 with the same flanking structure of upstream ΔISEcp1 and a downstream region identical to downstream bla KLUA-1 . IncT was the prevalent, and only, replicon found in 63 isolates. PFGE analysis detected eight clusters with more than one isolate, among which three included 56 isolates and six included isolates from multiple hospitals. CTX-M-2-producing P. mirabilis with an identical genetic structure flanking bla CTX-M-2 is dominant in this Japanese region, and there is evidence for the clonal spread of isolates.

Recent proposals to reform primary care have encouraged physician practices to adopt such structural capabilities as performance feedback and electronic health records. Whether practices with these capabilities have higher performance on measures of primary care quality is unknown. To measure associations between structural capabilities of primary care practices and performance on commonly used quality measures. Cross-sectional analysis. Massachusetts. 412 primary care practices. During 2007, 1 physician from each participating primary care practice (median size, 4 physicians) was surveyed about structural capabilities of the practice (responses representing 308 practices were obtained). Data on practice structural capabilities were linked to multipayer performance data on 13 Healthcare Effectiveness Data and Information Set (HEDIS) process measures in 4 clinical areas: screening, diabetes, depression, and overuse. Frequently used multifunctional electronic health records were associated with higher performance on 5 HEDIS measures (3 in screening and 2 in diabetes), with statistically significant differences in performance ranging from 3.1 to 7.6 percentage points. Frequent meetings to discuss quality were associated with higher performance on 3 measures of diabetes care (differences ranging from 2.3 to 3.1 percentage points). Physician awareness of patient experience ratings was associated with higher performance on screening for breast cancer and cervical cancer (1.9 and 2.2 percentage points, respectively). No other structural capabilities were associated with performance on more than 1 measure. No capabilities were associated with performance on depression care or overuse. Structural capabilities of primary care practices were assessed by physician survey. Among the investigated structural capabilities of primary care practices, electronic health records were associated with higher performance across multiple HEDIS measures.

Knowledge of structural class is used by numerous methods for identification of structural/functional characteristics of proteins and could be used for the detection of remote homologues, particularly for chains that share twilight-zone similarity. In contrast to existing sequence-based structural class predictors, which target four major classes and which are designed for high identity sequences, we predict seven classes from sequences that share twilight-zone identity with the training sequences. The proposed MODular Approach to Structural class prediction (MODAS) method is unique as it allows for selection of any subset of the classes. MODAS is also the first to utilize a novel, custom-built feature-based sequence representation that combines evolutionary profiles and predicted secondary structure. The features quantify information relevant to the definition of the classes including conservation of residues and arrangement and number of helix/strand segments. Our comprehensive design considers 8 feature selection methods and 4 classifiers to develop Support Vector Machine-based classifiers that are tailored for each of the seven classes. Tests on 5 twilight-zone and 1 high-similarity benchmark datasets and comparison with over two dozens of modern competing predictors show that MODAS provides the best overall accuracy that ranges between 80% and 96.7% (83.5% for the twilight-zone datasets), depending on the dataset. This translates into 19% and 8% error rate reduction when compared against the best performing competing method on two largest datasets. The proposed predictor provides accurate predictions at 58% accuracy for membrane proteins class, which is not considered by majority of existing methods, in spite that this class accounts for only 2% of the data. Our predictive model is analyzed to demonstrate how and why the input features are associated with the corresponding classes. The improved predictions stem from the novel features that express collocation

STRUCTURAL AND HIDDEN BARRIERS TO A LOCAL PRIMARY HEALTH CARE INFRASTRUCTURE: AUTONOMY, DECISIONS ABOUT PRIMARY HEALTH CARE, AND THE CENTRALITY AND SIGNIFICANCE OF POWER.

Freed, Christopher R; Hansberry, Shantisha T; Arrieta, Martha I

2013-09-01

To examine a local primary health care infrastructure and the reality of primary health care from the perspective of residents of a small, urban community in the southern United States. Data derive from 13 semi-structured focus groups, plus three semi-structured interviews, and were analyzed inductively consistent with a grounded theory approach. Structural barriers to the local primary health care infrastructure include transportation, clinic and appointment wait time, and co-payments and health insurance. Hidden barriers consist of knowledge about local health care services, non-physician gatekeepers, and fear of medical care. Community residents have used home remedies and the emergency department at the local academic medical center to manage these structural and hidden barriers. Findings might not generalize to primary health care infrastructures in other communities, respondent perspectives can be biased, and the data are subject to various interpretations and conceptual and thematic frameworks. Nevertheless, the structural and hidden barriers to the local primary health care infrastructure have considerably diminished the autonomy community residents have been able to exercise over their decisions about primary health care, ultimately suggesting that efforts concerned with increasing the access of medically underserved groups to primary health care in local communities should recognize the centrality and significance of power. This study addresses a gap in the sociological literature regarding the impact of specific barriers to primary health care among medically underserved groups.

Identity-based motivation: Implications for intervention

Oyserman, Daphna; Destin, Mesmin

2010-01-01

Children want to succeed academically and attend college, but their actual attainment often lags behind; some groups (e.g., boys, low-income children) are particularly likely to experience this gap. Social structural factors matter, influencing this gap in part by affecting children's perceptions of what is possible for them and people like them in the future. Interventions that focus on this macro-micro interface can boost children's attainment. We articulate the processes underlying these effects using an integrative culturally sensitive framework entitled identity-based motivation (IBM, Oyserman, 2007, 2009a, 2009b). The IBM model assumes that identities are dynamically constructed in context. People interpret situations and difficulties in ways that are congruent with currently active identities and prefer identity-congruent to identity-incongruent actions. When action feels identity-congruent, experienced difficulty highlights that the behavior is important and meaningful. When action feels identity-incongruent, the same difficulty suggests that the behavior is pointless and “not for people like me.” PMID:21516204

"They're younger… it's harder." Primary providers' perspectives on hypertension management in young adults: a multicenter qualitative study.

Young adults (18-39 year-olds) have the lowest hypertension control rates among adults with hypertension in the United States. Unique barriers to hypertension management in young adults with primary care access compared to older adults have not been evaluated. Understanding these differences will inform the development of hypertension interventions tailored to young adults. The goals of this multicenter study were to explore primary care providers' perspectives on barriers to diagnosing, treating, and controlling hypertension among young adults with regular primary care. Primary care providers (physicians and advanced practice providers) actively managing young adults with uncontrolled hypertension were recruited by the Wisconsin Research & Education Network (WREN), a statewide practice-based research network. Semi-structured qualitative interviews were conducted in three diverse Midwestern clinical practices (academic, rural, and urban clinics) using a semi-structured interview guide, and content analysis was performed. Primary care providers identified unique barriers across standard hypertension healthcare delivery practices for young adults. Altered self-identity, greater blood pressure variability, and unintended consequences of medication initiation were critical hypertension control barriers among young adults. Gender differences among young adults were also noted as barriers to hypertension follow-up and antihypertensive medication initiation. Tailored interventions addressing the unique barriers of young adults are needed to improve population hypertension control. Augmenting traditional clinic structure to support the "health identity" of young adults and self-management skills are promising next steps to improve hypertension healthcare delivery.

Exploring the positional identities of high school science teachers

Blackwell, Edith Lavonne

The identity of the teacher has been determined to influence classroom practices. Positional identity is defined as one's perception of self relative to others. This qualitative research study investigates the positional identity of five high school science teachers of different ethnicities and how their positional identities influence their classroom practices. Positional identity is thought to be determined by one's perception of how one's race, ethnicity, gender, age, religion and socioeconomic status position one relative to others. The methods of data collection included classroom observations, structured and semi-structured interviews, book club meetings, teacher journals, and researcher journals, demographic and online questionnaires. The teachers that overcame stereotypes based on race/ethnicity, gender and socioeconomic status felt empowered in their positional identities and were able to empower their students. The data also identified those teachers that struggle the most with finding their power within their positional identities were the immigrants that were not able to merge their personal identities within the pre-determined social positions they encountered in this society. The empowerment or powerlessness of the science teachers' positional identities impacted instruction and practices within the science classroom.

2009-01-01

The present study was designed to investigate trajectories of identity development and their relationship to family functioning in a sample of Hispanic adolescents and their primary caregivers. Two hundred fifty adolescents completed measures of identity coherence and confusion and of family functioning, and parents completed measures of family functioning. Significant variability over time and across individuals emerged in identity confusion, but not in identity coherence. As a result, the present analyses focused on identity confusion. Changes in adolescent-reported, but not parent-reported, family functioning were significantly related to changes in identity confusion. Follow-up analyses suggested that family functioning primarily influences identity confusion in early adolescence, but that identity confusion begins to exert a reciprocal effect in middle adolescence. Exploratory latent growth mixture modeling (LGMM) analyses produced three classes of adolescents based on their baseline values and change trajectories in identity confusion. The potential for family-strengthening interventions to affect identity development is discussed. PMID:19756226

Lesbian, gay, and bisexual (LGB) adults have higher rates of smoking than heterosexual adults. LGB individuals face unique stressors, including challenges associated with having a LGB identity. The extent to which these unique stressors are related to dependence motives in LGB adult smokers, however, has not been previously explored. The current study was conducted to redress these gaps. Participants (N = 52; Mage = 42.8; 55.8% Black/African American) were recruited from the local community. Identity facets were measured by the Lesbian, Gay, and Bisexual Identity Scale (LGBIS). Dependence motives were measured by the Brief Wisconsin Inventory of Smoking Dependence Motives. Linear multiple regressions were calculated with the predictors of seven LGBIS subscales for primary and secondary dependence motives, respectively. Primary dependence motives (core nicotine dependence features) were predicted by affirmation of LGB identity (β = 0.44). Secondary dependence motives (eg, taste, cognitive/affective enhancement) were predicted by uncertainty of LGB identity (β = 0.43). LGB identity affirmation was associated with primary dependence motives, suggesting that a positive view of one's sexual orientation is a risk factor for dependence. It may be that identity affirmation is related to stronger involvement with the LGB community, which has smoking-friendly norms. Identity uncertainty was associated with secondary dependence motives; this unique identity challenge may represent a stressor contributing to smoking dependence. Findings can help explain the higher rate of smoking in LGB populations and offer avenues to better tailor smoking cessation interventions. The current study is the first to examine multidimensional aspects of LGB identity in explaining smoking dependence motives among LGB adults. Results reveal that LGB identity challenges are associated with dependence motives, suggesting that interventions targeting these challenges may be help reduce LGB smoking

ABSTRACT OBJECTIVE The objective of this study is to investigate whether the characteristics of the structure of primary health units and the work process of primary care teams are associated with the number of hospitalizations for primary care sensitive conditions. METHODS In this ecological study, we have analyzed data of Brazilian municipalities related to sociodemographic characteristics, coverage of care programs, structure of primary health units, and work process of primary care teams. We have obtained the data from the first cycle of the Brazilian Program for Improving Access and Quality of the Primary Care, of the Department of Information Technology of the Brazilian Unified Health System, the Brazilian Institute of Geography and Statistics, and the United Nations Development Programme. The associations have been estimated using negative binomial regression coefficients (β) and respective 95% confidence intervals, with a hierarchical approach in three levels (alpha = 5%). RESULTS In the adjusted analysis for the outcome in 2013, in the distal level, the coverage of the Bolsa Família Program (β = -0.001) and private insurance (β = -0.01) had a negative association, and the human development index (β = 1.13), the proportion of older adults (β = 0.05) and children under the age of five (β = 0.05), and the coverage of the Community Health Agent Strategy (β = 0.002) showed positive association with hospitalizations for primary care sensitive conditions. In the intermediate level, minimum hours (β = -0.14) and availability of vaccines (β = -0.16) showed a negative association, and availability of medications showed a positive association (β = 0.16). In the proximal level, only the variable of matrix support (β = 0.10) showed a positive association. The variables in the adjusted analysis of the number of hospitalizations for primary care sensitive conditions in 2014 presented the same association as in 2013. CONCLUSIONS The characteristics of the

O'Riordan, Chris; McDermott, Aoife

The purpose of this paper is to explore the nature and value of the clinical management role undertaken by primary care doctors in Ireland. To date, a majority of research has focused on clinical management roles in the acute sector. The paper presents a sub-set of data from a mixed methods study. In total, 14 semi-structured interviews are drawn upon to identify the nature and value of the clinical management role in primary care. Comparison with acute sector research identifies considerable differences in the nature of the clinical management role across sectors--and in the associated value proposition. Structural and role-related contingencies affecting the potential value of clinical management roles in Irish primary care are discussed. Structural influences include the private ownership structure, low complexity and limited requirement for cross-professional coordination. Role-related influences include the primacy of the clinical identity, time constraints and lack of managerial training. The findings provide a limited basis for generalisation, premised on 14 interviews in one national context. However, given the international shift towards the provision of health services in primary care, they provide a research agenda for an important healthcare context. The findings draw attention to the need for policy consideration of the value of the clinical manager role in primary care; how policy can support effective primary care management; and the need for specialised management training, which takes account of the small-firm context. The paper identifies that primary-care clinical-management roles focus on operational management and oversight and discusses the structural and role-related factors which affect their efficacy.

This study examined the roles of identity formation and moral identity in predicting college student mental health (anxiety and depressive symptoms), health-risk behaviors (hazardous alcohol use and sexual risk taking), and psychological well-being (self-esteem and meaning). The sample comprised 9,500 college students (aged 18-25 years, mean = 19.78, standard deviation = 1.61; 73% female; 62% European American), from 31 different universities, who completed an online self-report survey. Structural equation models found that identity maturity (commitment making and identity synthesis) predicted 5 of the health outcomes (except sexual risk taking), and moral identity predicted all of the health outcomes. In most cases identity maturity and moral identity also interacted in predicting mental health and psychological well-being, but not health-risk behaviors. The maturity and specific contents of identity may both play unique and often interactive roles in predicting college student health. Thus, college student health might be bolstered by helping them establish appropriate identity commitments. © 2012 Wiley Periodicals, Inc.

2017-09-01

We give an elegant formulation of the structure equations (of Cartan) and the Bianchi identities in terms of exterior calculus without reference to a particular basis and without the exterior covariant derivative. This approach allows both structure equations and the Bianchi identities to be expressed in terms of forms of arbitrary degree. We demonstrate the relationship with both the conventional vector version of the Bianchi identities and to the exterior covariant derivative approach. Contact manifolds, codimension one foliations and the Cartan form of classical mechanics are studied as examples of its flexibility and utility.

Integrated primary health care: Finnish solutions and experiences

PubMed Central

Kokko, Simo

2009-01-01

Background Finland has since 1972 had a primary health care system based on health centres run and funded by the local public authorities called ‘municipalities’. On the world map of primary health care systems, the Finnish solution claims to be the most health centre oriented and also the widest, both in terms of the numbers of staff and also of different professions employed. Offering integrated care through multi-professional health centres has been overshadowed by exceptional difficulties in guaranteeing a reasonable access to the population at times when they need primary medical or dental services. Solutions to the problems of access have been found, but they do not seem durable. Description of policy practice During the past 10 years, the health centres have become a ground of active development structural change, for which no end is in sight. Broader issues of municipal and public administration structures are being solved through rearranging primary health services. In these rearrangements, integration with specialist services and with social services together with mergers of health centres and municipalities are occurring at an accelerated pace. This leads into fundamental questions of the benefits of integration, especially if extensive integration leads into the threat of the loss of identity for primary health care. Discussion This article ends with some lessons to be learned from the situation in Finland for other countries. PMID:19590612

Early perception and structural identity: neural implementation

NASA Astrophysics Data System (ADS)

Ligomenides, Panos A.

1992-03-01

It is suggested that there exists a minimal set of rules for the perceptual composition of the unending variety of spatio-temporal patterns in our perceptual world. Driven by perceptual discernment of "sudden change" and "unexpectedness", these rules specify conditions (such as co-linearity and virtual continuation) for perceptual grouping and for recursive compositions of perceptual "modalities" and "signatures". Beginning with a smallset of primitive perceptual elements, selected contextually at some relevant level of abstraction, perceptual compositions can graduate to an unlimited variety of spatiotemporal signatures, scenes and activities. Local discernible elements, often perceptually ambiguous by themselves, may be integrated into spatiotemporal compositions, which generate unambiguous perceptual separations between "figure" and "ground". The definition of computational algorithms for the effective instantiation of the rules of perceptual grouping remains a principal problem. In this paper we present our approach for solving the problem of perceptual recognition within the confines of one-D variational profiles. More specifically, concerning "early" (pre-attentive) recognition, we define the "structural identity of a k-norm, k ∈ K,"--SkID--as a tool for discerning and locating the instantiation of spatiotemporal objects or events. The SkID profile also serves a s a reference coordinate framework for the "perceptual focusing of attention" and the eventual assessment of resemblance. Neural network implementations of pre-attentive and attentive recognition are also discussed briefly. Our principles are exemplified by application to one-D perceptual profiles, which allows simplicity of definitions and of the rules of perceptual composition.

The United States Department of Veterans Affairs Connecticut Healthcare System (VACHS) is one of five Centers of Excellence in Primary Care Education (CoEPCE) pilot sites. The overall goal of the CoEPCE program, which is funded by the Office of Academic Affiliations, is to develop and implement innovative approaches for training future health care providers in postgraduate education programs to function effectively in teams to provide exceptional patient care. This longitudinal study employs theoretically grounded qualitative methods to understand the effect of a combined nursing and medical training model on professional identity and team development at the VACHS CoEPCE site. The authors used qualitative approaches to understand trainees' experiences, expectations, and impressions of the program. From September 2011 to August 2012, they conducted 28 interviews of 18 trainees (internal medicine [IM] residents and nurse practitioners [NPs]) and subjected data to three stages of open, iterative coding. Major themes illuminate both the evolution of individual professional identity within both types of trainees and the dynamic process of group identity development. Results suggest that initially IM residents struggled to understand NPs' roles and responsibilities, whereas NP trainees doubted their ability to work alongside physicians. At the end of one academic year, these uncertainties disappeared, and what was originally artificial had transformed into an organic interprofessional team of health providers who shared a strong sense of understanding and trust. This study provides early evidence of successful interprofessional collaboration among NPs and IM residents in a primary care training program.

This article develops theoretical understanding of the involvement of wealthy entrepreneurs in socially transformative projects by offering a foundational theory of philanthropic identity narratives. We show that these narratives are structured according to the metaphorical framework of the journey , through which actors envision and make sense of personal transformation. The journey provides a valuable metaphor for conceptualizing narrative identities in entrepreneurial careers as individuals navigate different social landscapes, illuminating identities as unfolding through a process of wayfinding in response to events, transitions and turning-points. We delineate the journey from entrepreneurship to philanthropy, and propose a typology of rewards that entrepreneurs claim to derive from giving. We add to the expanding literature on narrative identities by suggesting that philanthropic identity narratives empower wealthy entrepreneurs to generate a legacy of the self that is both self- and socially oriented, these 'generativity scripts' propelling their capacity for action while ensuring the continuation of their journeys.

Textile laminates, developed a number of years ago, have recently been shown to be applicable to primary aircraft structures for both small and large components. Such structures have the potential to reduce acquisition costs but require advanced automated processing to keep costs controlled while verifying product reliability and assuring structural integrity, durability and affordable life-cycle costs. Recently, resin systems and graphite-reinforced woven shapes have been developed that have the potential for improved RTM processes for aircraft structures. Ciba-Geigy, Brochier Division has registered an RTM prepreg reinforcement called 'Injectex' that has shown effectivity for aircraft components. Other novel approaches discussed are thermotropic resins producing components by injection molding and ceramic polymers for long-duration hot structures. The potential of such materials and processing will be reviewed along with initial information/data available to date.

In this paper, we report on the structural nexus of one youth's gaming practices across contexts and over time. We utilize data from an ethnography of youth science and technology learning, as well as expertise development, across settings and developmental time. We use Ole Dreier's theory of persons to understand how this youth is able to develop considerable gaming expertise. Additionally, we explicate the learning practices embedded in the structural nexus of this youth's gaming and we examine associated issues of learning and identity. We problematize the lack of continuity between his formal schooling experiences and the structural nexus of his gaming practices as situated in a variety of other contexts and we reflect on the implications for the design of STEM gaming experiences in formal school environments.

To describe the current structural and practice characteristics of the Department of Veterans Affairs (VA) Home-Based Primary Care (HBPC) program. We designed a national survey and surveyed HBPC program directors on-line using REDCap. We received 236 surveys from 394 identified HBPC sites (60% response rate). HBPC site characteristics were quantified using closed-ended formats. HBPC program directors were most often registered nurses, and HBPC programs primarily served veterans with complex chronic illnesses that were at high risk of hospitalization and nursing home care. Primary care was delivered using interdisciplinary teams, with nurses, social workers, and registered dietitians as team members in more than 90% of the sites. Most often, nurse practitioners were the principal primary care providers (PCPs), typically working with nurse case managers. Nearly 60% of the sites reported dual PCPs involving VA and community-based physicians. Nearly all sites provided access to a core set of comprehensive services and programs (e.g., case management, supportive home health care). At the same time, there were variations according to site (e.g., size, location (urban, rural), use of non-VA hospitals, primary care models used). HBPC sites reflected the rationale and mission of HBPC by focusing on complex chronic illness of home-based veterans and providing comprehensive primary care using interdisciplinary teams. Our next series of studies will examine how HBPC site structural characteristics and care models are related to the processes and outcomes of care to determine whether there are best practice standards that define an optimal HBPC structure and care model or whether multiple approaches to HBPC better serve the needs of veterans.

Background: In recent years, family physician plan was established as the main strategy of health system in Iran, while organizational structure of the primary health care system has remained the same as thirty years ago. Objectives: This study was performed to illustrate structural and contextual dimensions of organizational structure and relationship between them in Iranian primary health care system at local level. Materials and Methods: A cross-sectional quantitative study was conducted from January to June 2013, during which 121 questionnaires were distributed among senior and junior managers of city health centers at Medical Sciences universities in Iran. Validity of the questionnaire was confirmed by experts (CVI = 0.089 and CVR more than 0.85) and Cronbach α was utilized for reliability (α = 0.904). We used multistage sampling method in this study and analysis of the data was performed by SPSS software using different tests. Results: Local level of primary health care system in Iran had mechanical structure, but in contextual dimensions the results showed different types. There was a significant relationship between structural and contextual dimensions (r = 0.642, P value < 0.001). Goals and culture dimensions had strongest effects on structural dimensions. Conclusions: Because of the changes in goals and strategies of Iranian health system in recent years, it is urgently recommended to reform the current structure to increase efficiency and effectiveness of the system.

Binary asteroid orbit evolution due to primary shape deformation

Hirabayashi, Masatoshi; Jacobson, Seth A.; Davis, Alex

2017-10-01

About a sixth of all small asteroid systems are binary [Margot et al., Science, 2002]. Many binary asteroids consist of an elongated synchronous secondary body orbiting a fast-rotating spheroidal primary body with ridges on its equator. The primary in such systems has experienced a long-term spin-up due to the YORP effect [Vokrouhlick'y et al., Asteroid IV, 2015]. This spin-up process can make the primary reach its spin barrier inducing shape deformation processes that ease the structural condition for failure inside the primary [e.g., Holsapple, Icarus, 2010]. Earlier works have shown that structural heterogeneities in the primary such as the shape and density distribution induce asymmetric deformation [Sánchez and Scheeres, Icarus, 2016]. Here, we investigate how asymmetric shape deformation in the primary affects the mutual motion of a binary system. We use a dynamics model for an irregularly shaped binary system that accounts for possible deformation of the primary [Hirabayashi et al., LPSC, 2017]. In this model, we consider asymmetric deformation that occurs based on structural failure in the primary and thus it modifies the location of the center of mass of the system. Using 1999 KW4 as an example, we study a hypothetical case in which the primary is initially identical to the current shape [Ostro et al., Science, 2006] with an aspect ratio (AR) of 0.83 and then suddenly changes its shape to an AR of 0.76. The results show that the asymmetric deformation process and the shift of the center of mass excite the eccentricity of the mutual orbit. Considering that the original mutual orbit has an eccentricity of 0.0004, after the primary shape change the eccentricity reaches values up to 0.15. Also, since the gravity field is modified after deformation, the secondary’s spin is desynchronized from the mutual orbit. Since synchronicity is a requirement for the binary YORP (BYORP) effect, which modifies the semi-major axis of binary asteroids, a primary shape

Oral and maxillofacial surgery - a case of mistaken identity?

PubMed

van Gijn, D R

2011-01-08

There are international grumbles from those perturbed by an impending identity crisis within oral and maxillofacial surgery (OMFS). This unrest is further compounded by scattered suggestions that a name change may prove beneficial in raising the profile of OMFS. The purpose of this paper is to consider novel methods of increasing awareness of the specialty amongst the public, primary and secondary care colleagues by collecting a consensus of thoughts and opinions regarding the specialty's identity and the appropriate and holistic nomenclature of OMFS. Approximately 300 eight-point questionnaires were distributed internationally with a response rate, via both email and post, of approximately 25% (72). Thirty-two percent of respondents considered there to be an identity crisis within OMFS although just 18% felt that a specialty name change would be beneficial. The results suggest that the problem with identity relates more to incapacity to convey the message of OMFS rather than nomenclature.

Carbon-carbon primary structure for SSTO vehicles

A hot structures development program is nearing completion to validate use of carbon-carbon composite structure for primary load carrying members in a single-stage-to-orbit, or SSTO, vehicle. A four phase program was pursued which involved design development and fabrication of a full-scale wing torque box demonstration component. The design development included vehicle and component selection, design criteria and approach, design data development, demonstration component design and analysis, test fixture design and analysis, demonstration component test planning, and high temperature test instrumentation development. The fabrication effort encompassed fabrication of structural elements for mechanical property verification as well as fabrication of the demonstration component itself and associated test fixturing. The demonstration component features 3D woven graphite preforms, integral spars, oxidation inhibited matrix, chemical vapor deposited (CVD) SiC oxidation protection coating, and ceramic matrix composite fasteners. The demonstration component has been delivered to the United States Air Force (USAF) for testing in the Wright Laboratory Structural Test Facility, WPAFB, OH. Multiple thermal-mechanical load cycles will be applied simulating two atmospheric cruise missions and one orbital mission. This paper discusses the overall approach to validation testing of the wing box component and presents some preliminary analytical test predictions.

Management of hypertension can lead to significant reductions in blood pressure, thereby reducing the risk of cardiovascular disease. Modeling the course of cardiovascular disease is not without complications, and uncertainty surrounding the structure of a model will almost always arise once a choice of a model structure is defined. To provide a practical illustration of the impact on the results of cost-effectiveness of changing or adapting model structures in a previously published cost-utility analysis of a primary care intervention for the management of hypertension Targets and Self-Management for the Control of Blood Pressure in Stroke and at Risk Groups (TASMIN-SR). The case study assessed the structural uncertainty arising from model structure and from the exclusion of secondary events. Four alternative model structures were implemented. Long-term cost-effectiveness was estimated and the results compared with those from the TASMIN-SR model. The main cost-effectiveness results obtained in the TASMIN-SR study did not change with the implementation of alternative model structures. Choice of model type was limited to a cohort Markov model, and because of the lack of epidemiological data, only model 4 captured structural uncertainty arising from the exclusion of secondary events in the case study model. The results of this study indicate that the main conclusions drawn from the TASMIN-SR model of cost-effectiveness were robust to changes in model structure and the inclusion of secondary events. Even though one of the models produced results that were different to those of TASMIN-SR, the fact that the main conclusions were identical suggests that a more parsimonious model may have sufficed.

Acculturative dissonance, ethnic identity, and youth violence.

PubMed

Le, Thao N; Stockdale, Gary

2008-01-01

Studies suggest that the process of acculturation for immigrant youth, particularly for second-generation youth, is significantly associated with delinquency and violence. This study explored the acculturation-violence link with respect to acculturative dissonance and ethnic identity. The results revealed in a sample of 329 Chinese, Cambodian, Mien/Laotian, and Vietnamese youth that acculturative dissonance was significantly predictive of serious violence, with full mediation through peer delinquency. Ethnic identity was not significantly associated with peer delinquency or serious violence. Although acculturative dissonance and ethnic identity accounted for a small percentage of variance in violence compared with peer delinquency, it cannot be discounted as trivial. Structural equation analyses provided support for both measurement and structural invariance across the four ethnic groups, lending support for cross-cultural comparisons. The results also lend support for the inclusion of cultural factors in youth violence prevention and intervention efforts. 2008 APA

A perspective on the primary and three-dimensional structures of carbohydrates.

PubMed

Widmalm, Göran

2013-08-30

Carbohydrates, in more biologically oriented areas referred to as glycans, constitute one of the four groups of biomolecules. The glycans, often present as glycoproteins or glycolipids, form highly complex structures. In mammals ten monosaccharides are utilized in building glycoconjugates in the form of oligo- (up to about a dozen monomers) and polysaccharides. Subsequent modifications and additions create a large number of different compounds. In bacteria, more than a hundred monosaccharides have been reported to be constituents of lipopolysaccharides, capsular polysaccharides, and exopolysaccharides. Thus, the number of polysaccharide structures possible to create is huge. NMR spectroscopy plays an essential part in elucidating the primary structure, that is, monosaccharide identity and ring size, anomeric configuration, linkage position, and sequence, of the sugar residues. The structural studies may also employ computational approaches for NMR chemical shift predictions (CASPER program). Once the components and sequence of sugar residues have been unraveled, the three-dimensional arrangement of the sugar residues relative to each other (conformation), their flexibility (transitions between and populations of conformational states), together with the dynamics (timescales) should be addressed. To shed light on these aspects we have utilized a combination of experimental liquid state NMR techniques together with molecular dynamics simulations. For the latter a molecular mechanics force field such as our CHARMM-based PARM22/SU01 has been used. The experimental NMR parameters acquired are typically (1)H,(1)H cross-relaxation rates (related to NOEs), (3)JCH and (3)JCCtrans-glycosidic coupling constants and (1)H,(13)C- and (1)H,(1)H-residual dipolar couplings. At a glycosidic linkage two torsion angles ϕ and ψ are defined and for 6-substituted residues also the ω torsion angle is required. Major conformers can be identified for which highly populated states are

Background Forming one’s identity is thought to be the key developmental task of adolescence, but profound changes in personality traits also occur in this period. The negotiation of complex social settings, the creation of an integrated identity, and career choice are major tasks of adolescence. The adolescent, having to make choices for his or her future, has not only to consider his or her own aspirations and interests but also to possess a capacity for exploration and commitment; in fact, career commitments can be considered as a fit between the study or career that is chosen and personal values, skills, and preferences. Methods The objective of the study reported here was to investigate the role of identity on profile of interests; the relation between identity and decisional style; the correlation between identity, aptitudes, interests, and school performance; and the predictive variables to school success. The research involved 417 Italian students who live in Enna, a small city located in Sicily, Italy, aged 16–19 years (197 males and 220 females) in the fourth year (mean =17.2, standard deviation =0.52) and the fifth year (mean =18.2, standard deviation =0.64) of senior secondary school. The research lasted for one school year; the general group of participants consisted of 470 students, and although all participants agreed to be part of the research, there was a dropout rate of 11.28%. They completed the Ego Identity Process Questionnaire to measure their identity development, the Intelligence Structure Test to investigate aptitudes, the Self-Directed Search to value interests, and General Decision Making Style questionnaire to describe their individual decisional style. Results The data showed that high-school performance was positively associated with rational decision-making style and identity diffusion predicted the use of avoidant style. Interests were related to identity exploration; the differentiation of preferences was related to identity

2003-04-01

Three years after being interviewed, a nonrandom, purposeful subsample of 14 Jewish families from a larger sample of 48 families living in Central New York was reinterviewed. The primary aim of this follow-up study was to develop a descriptive understanding of parenting practices and the transmission of ethnic identity. Semistructured family interviews were conducted and coded using grounded-theory techniques, in particular the constant comparative method of analysis. Four main qualitative categories emerged from this study: Individual differences in teenagers, stages of ethnic identity development, parenting practices, and parental role models. Findings suggest that clear expectations, a type of authoritative parenting, could be associated with the positive transmission of Jewish ethnic identity. This type of parenting style was direct as parents expressed clear expectations for participation in Jewish activities both at home and in the community.

Chiropractic Identity: A Neurological, Professional, and Political Assessment.

2016-12-01

The purpose of this article is to propose a focused assessment of the identity of chiropractic and its profession, triangulating multiple viewpoints converging upon various aspects and definitions of neurology, manual medicine, and alternative or mainstream medicine. Over 120 years since its inception, chiropractic has struggled to achieve an identity for which its foundations could provide optimal health care. Despite recognition of the benefits of spinal manipulation in various government guidelines, advances in US military and Veterans Administration, and persistently high levels of patient satisfaction, the chiropractic profession remains underrepresented in most discussions of health care delivery. Distinguishing characteristics of doctors of chiropractic include the following: (1) they embrace a model of holistic, preventive medicine (wellness); (2) they embrace a concept of neurological imbalance in which form follows function, disease follows disturbed biochemistry, and phenomenology follows physiology; (3) they diagnose, and their institutions of training are accredited by a body recognized by the US Department of Education; (4) they manage patients on a first-contact basis, often as primary care providers in geographical areas that are underserved; (5) the spine is their primary-but not exclusive-area of interaction; (6) they deliver high-velocity, low-amplitude adjustments with a superior safety record compared with other professions; and (7) they use a network of institutions worldwide that have shown increasing commitments to research. This article provides an overview of chiropractic identity from 6 points of view: (1) concepts of manual medicine; (2) areas of interest beyond the spine; (3) concepts of the chiropractic subluxation; (4) concepts of neurology; (5) concepts of mainstream or alternative health care; and (6) concepts of primary care, first-contact provider, or specialist.

Constructing nurses' professional identity through social identity theory.

Willetts, Georgina; Clarke, David

2014-04-01

The profession of nursing continues to struggle with defining and clarifying its professional identity. The definitive recognition of nursing as a profession was the moving of training from the hospital apprentice model to the tertiary sector. However, this is only part of the story of professional identity in nursing. Once training finishes and enculturation into the workplace commences, professional identity becomes a complicated social activity. This paper proposes social identity theory as a valuable research framework to assist with clarifying and describing the professional identity of nurses. The paper outlines the key elements of a profession and then goes on to describe the main concepts of social identity theory. Lastly, a connection is made between the usefulness of using social identity theory in researching professional identity in nursing, recognizing the contextual nature of the social activity of the profession within its workplace environment. © 2013 Wiley Publishing Asia Pty Ltd.

Primary cilia are increased in number and demonstrate structural abnormalities in human cancer.

Primary cilia play an important role in the regulation of cell signalling pathways and are thought to have a role in cancer but have seldom been studied in human cancer samples. Primary cilia were visualised by dual immunofluorescence for anti-CROCC (ciliary rootlet coiled-coil) and anti-tubulin in a range of human cancers (including carcinomas of stomach, pancreas, prostate, lung and colon, lobular and ductal breast cancers and follicular lymphoma) and in matched normal tissue (stomach, pancreas, lung, large and small intestines, breast and reactive lymph nodes) samples using a tissue microarray; their frequency, association with proliferation, was measured by Ki-67 staining and their structure was analysed. Compared with normal tissues, primary cilia frequency was significantly elevated in adenocarcinoma of the lung (2.75% vs 1.85%, p=0.016), adenocarcinoma of the colon (3.80% vs 2.43%, respectively, p=0.017), follicular lymphoma (1.18% vs 0.83%, p=0.003) and pancreatic adenocarcinoma (7.00% vs 5.26%, p=0.002); there was no statistically significant difference compared with normal control tissue for gastric and prostatic adenocarcinomas or for lobular and ductal breast cancers. Additionally, structural abnormalities of primary cilia were identified in cancer tissues, including elongation of the axoneme, multiple basal bodies and branching of the axoneme. Ki-67 scores ranged from 0.7% to 78.4% and showed no statistically significant correlation with primary cilia frequency across all tissues (p=0.1501). The results show upregulation of primary cilia and the presence of structural defects in a wide range of human cancer tissue samples demonstrating association of dysregulation of primary cilia with human cancer.

In the primary walls of growing plant cells, the glucose polymer cellulose is assembled into long microfibrils a few nanometers in diameter. The rigidity and orientation of these microfibrils control cell expansion; therefore, cellulose synthesis is a key factor in the growth and morphogenesis of plants. Celery (Apium graveolens) collenchyma is a useful model system for the study of primary wall microfibril structure because its microfibrils are oriented with unusual uniformity, facilitating spectroscopic and diffraction experiments. Using a combination of x-ray and neutron scattering methods with vibrational and nuclear magnetic resonance spectroscopy, we show that celery collenchyma microfibrils were 2.9 to 3.0 nm in mean diameter, with a most probable structure containing 24 chains in cross section, arranged in eight hydrogen-bonded sheets of three chains, with extensive disorder in lateral packing, conformation, and hydrogen bonding. A similar 18-chain structure, and 24-chain structures of different shape, fitted the data less well. Conformational disorder was largely restricted to the surface chains, but disorder in chain packing was not. That is, in position and orientation, the surface chains conformed to the disordered lattice constituting the core of each microfibril. There was evidence that adjacent microfibrils were noncovalently aggregated together over part of their length, suggesting that the need to disrupt these aggregates might be a constraining factor in growth and in the hydrolysis of cellulose for biofuel production.

Neuroblastoma is a tumor of the peripheral sympathetic nervous system, derived from multipotent neural crest cells (NCCs). To define core regulatory circuitries (CRCs) controlling the gene expression program of neuroblastoma, we established and analyzed the neuroblastoma super-enhancer landscape. We discovered three types of identity in neuroblastoma cell lines: a sympathetic noradrenergic identity, defined by a CRC module including the PHOX2B, HAND2 and GATA3 transcription factors (TFs); an NCC-like identity, driven by a CRC module containing AP-1 TFs; and a mixed type, further deconvoluted at the single-cell level. Treatment of the mixed type with chemotherapeutic agents resulted in enrichment of NCC-like cells. The noradrenergic module was validated by ChIP-seq. Functional studies demonstrated dependency of neuroblastoma with noradrenergic identity on PHOX2B, evocative of lineage addiction. Most neuroblastoma primary tumors express TFs from the noradrenergic and NCC-like modules. Our data demonstrate a previously unknown aspect of tumor heterogeneity relevant for neuroblastoma treatment strategies.

The Multicultural Identity Integration Scale (MULTIIS): Developing a comprehensive measure for configuring one's multiple cultural identities within the self.

2016-04-01

The research investigating how one's multiple cultural identities are configured within the self has yet to account for existing cultural identity configurations aside from integration, and for identifying with more than 2 cultural groups at once. The current research addresses these issues by constructing the Multicultural Identity Integration Scale (MULTIIS) to examine 3 different multicultural identity configurations, and their relationship to well-being based on Amiot and colleagues' (2007) cognitive-developmental model of social identity integration (CDSMII). Diverse samples of multicultural individuals completed the MULTIIS along with identity and well-being measures. (Study 1A: N = 407; 1B: N = 310; 2A = 338 and 2A = 254) RESULTS: Reliability and confirmatory factorial analyses (Studies 1A and 2A) all supported the factorial structure of the MULTIIS. Regression analyses (Studies 1B and 2B) confirmed that the integration subscale of the MULTIIS positively predicted well-being, whereas compartmentalization negatively predicted well-being. Categorization was inconsistently related to well-being. These findings support the CDSMII and the usefulness of the MULTIIS measure, and suggest that each identity configuration is uniquely related to well-being outcomes.

Resolving an identity crisis: Implicit drinking identity and implicit alcohol identity are related but not the same.

Ramirez, Jason J; Olin, Cecilia C; Lindgren, Kristen P

2017-09-01

Two variations of the Implicit Association Test (IAT), the Drinking Identity IAT and the Alcohol Identity IAT, assess implicit associations held in memory between one's identity and alcohol-related constructs. Both have been shown to predict numerous drinking outcomes, but these IATs have never been directly compared to one another. The purpose of this study was to compare these IATs and evaluate their incremental predictive validity. US undergraduate students (N=64, 50% female, mean age=21.98years) completed the Drinking Identity IAT, the Alcohol Identity IAT, an explicit measure of drinking identity, as well as measures of typical alcohol consumption and hazardous drinking. When evaluated in separate regression models that controlled for explicit drinking identity, results indicated that the Drinking Identity IAT and the Alcohol Identity IAT were significant, positive predictors of typical alcohol consumption, and that the Drinking Identity IAT, but not the Alcohol Identity IAT, was a significant predictor of hazardous drinking. When evaluated in the same regression models, the Drinking Identity IAT, but not the Alcohol Identity IAT, was significantly associated with typical and hazardous drinking. These results suggest that the Drinking Identity IAT and Alcohol Identity IAT are related but not redundant. Moreover, given that the Drinking Identity IAT, but not the Alcohol Identity IAT, incrementally predicted variance in drinking outcomes, identification with drinking behavior and social groups, as opposed to identification with alcohol itself, may be an especially strong predictor of drinking outcomes.

The medical leadership challenge in healthcare is an identity challenge.

PubMed

Andersson, Thomas

2015-01-01

The purpose of this article is to describe and analyse the identity challenges that physicians with medical leadership positions face. Four qualitative case studies were performed to address the fact that identity is processual, relational and situational. Physicians with managerial roles were interviewed, as well as their peers, supervisors and subordinates. Furthermore, observations were made to understand how different identities are displayed in action. This study illustrates that medical leadership implies identity struggles when physicians have manager positions, because of the different characteristics of the social identities of managers and physicians. Major differences are related between physicians as autonomous individuals in a system and managers as subordinates to the organizational system. There are psychological mechanisms that evoke the physician identity more often than the managerial identity among physicians who are managers, which explains why physicians who are managers tend to remain foremost physicians. The implications of the findings, that there are major identity challenges by being both a physician and manager, suggest that managerial physicians might not be the best prerequisite for medical leadership, but instead, cooperative relationships between physicians and non-physician managers might be a less difficult way to support medical leadership. Acknowledging and addressing identity challenges can be important both in creating structures in organizations and designing the training for managers in healthcare (both physicians and non-physicians) to support medical leadership. Medical leadership is most often related to organizational structure and/or leadership skills, but this paper discusses identity requirements and challenges related to medical leadership.

Establishing an Explanatory Model for Mathematics Identity.

This article empirically tests a previously developed theoretical framework for mathematics identity based on students' beliefs. The study employs data from more than 9,000 college calculus students across the United States to build a robust structural equation model. While it is generally thought that students' beliefs about their own competence in mathematics directly impact their identity as a "math person," findings indicate that students' self-perceptions related to competence and performance have an indirect effect on their mathematics identity, primarily by association with students' interest and external recognition in mathematics. Thus, the model indicates that students' competence and performance beliefs are not sufficient for their mathematics identity development, and it highlights the roles of interest and recognition. © 2015 The Authors.

Modern women's identity crises and the various possibilities of identification along the way towards a new identity can be seen as her attempts to develop out of the depressive situation that her once normal role identity had, to a large extent, placed her in. Under this aspect, even concepts of living that are seen by many to be problematic can be justified as leading along the way towards identity, which is so essential for human relationships and interpersonal empathy.

Identity in agent-based models : modeling dynamic multiscale social processes.

DOE Office of Scientific and Technical Information (OSTI.GOV)

Ozik, J.; Sallach, D. L.; Macal, C. M.

Identity-related issues play central roles in many current events, including those involving factional politics, sectarianism, and tribal conflicts. Two popular models from the computational-social-science (CSS) literature - the Threat Anticipation Program and SharedID models - incorporate notions of identity (individual and collective) and processes of identity formation. A multiscale conceptual framework that extends some ideas presented in these models and draws other capabilities from the broader CSS literature is useful in modeling the formation of political identities. The dynamic, multiscale processes that constitute and transform social identities can be mapped to expressive structures of the framework

Identity processes as a predictor of memory beliefs in older adults.

PubMed

Hilgeman, Michelle M; Allen, Rebecca S; Carden, Keisha D

2017-07-01

The impact of identity processes (identity assimilation, identity accommodation, and identity balance) on memory beliefs was explored. Individually administered questionnaires (e.g. depressive symptoms, subjective health, identity processes, memory beliefs) and a brief neuropsychological assessment of cognitive abilities were completed during a one-time interview with 82 participants aged 58-92 years-old (M = 74.68, SD = 10.95). Forty (49.4%) identified their race as White/Caucasian, 38 (46.9%) identified their race as Black/African American, and 3 (3.7%) indicated no primary racial/ethnic group. Hierarchical regression analyses revealed that identity processes account for differences in memory beliefs beyond established predictors. Specifically, identity accommodation and identity balance predicted memory self-efficacy beyond depression and subjective health. These findings are congruent with identity process theory; however, the impact of identity assimilation in this population was unremarkable. Exploratory analyses also indicated that the identity processes have a stronger relationship to some domains of memory self-efficacy (i.e. anxiety, capacity) than others (i.e. perceived change, locus of control). Beliefs about memory and their integration into an adaptable, yet consistent self-concept are an important element of identity for aging individuals. Additional research is needed to determine the unique role of identity accommodation and identity balance in understanding cognitive functioning and ultimately the impact on potential clinical applications, such as related health-seeking behavior among older adults. Tailored interventions could be developed to facilitate optimal utilization of health care services at a time when early diagnosis of memory-related disorders is critical for future planning and care decisions.

Ethnic Identity and Perceived Stress Among Ethnically Diverse Immigrants.

2018-02-01

Recent empirical research suggests that having a strong ethnic identity may be associated with reduced perceived stress. However, the relationship between perceived stress and ethnic identity has not been tested in a large and ethnically diverse sample of immigrants. This study utilized a multi-group latent class analysis of ethnic identity on a sample of first and second generation immigrants (N = 1603), to determine ethnic identity classifications, and their relation to perceived stress. A 4-class ethnic identity structure best fit the data for this immigrant sample, and the proportion within each class varied by ethnicity, but not immigrant generation. High ethnic identity was found to be protective against perceived stress, and this finding was invariant across ethnicity. This study extends the findings of previous research on the protective effect of ethnic identity against perceived stress to immigrant populations of diverse ethnic origins.

This chapter begins with a discussion of the unique experience of adolescents and emerging adults who grew up with globalization in China and how it has affected their sense of self. We then discuss the effects of globalization on identity development in general, with a special focus on the sociohistorical context of China. We also review and critique the psychological literature that has been conducted on identity within Chinese and Chinese American populations. Finally, we discuss the applicability of Western concepts of identity on a culture that does not necessarily share the same value structure.

Positive Identity as a Positive Youth Development Construct: A Conceptual Review

Tsang, Sandra K. M.; Hui, Eadaoin K. P.; Law, Bella C. M.

2012-01-01

Identity is a core construct in psychology because it refers to how a person addresses issues dealing with who that person is. Important theorists studying the concept of identity, like Erikson, Marcia, and Higgins, assert that identity is organized,is learned, and is dynamic, and a subjective evaluation of an individual's identity has emotional consequences for that individual. Adolescents who can cultivate a clear and positive identity after their developmental struggles during adolescence often advance more smoothly into adulthood. This paper reviews literature on the nature and structure of identity and examines its importance on adolescent developmental outcomes. It traces significant determinants of identity and proposes strategies for cultivation of positive identity. Observations on current research gaps in the study of identity and future research directions will also be discussed. PMID:22649296

The influence of channel anion identity on the high-pressure crystal structure, compressibility, and stability of apatite

NASA Astrophysics Data System (ADS)

Skelton, Richard; Walker, Andrew M.

2018-03-01

The material properties of the common phosphate mineral apatite are influenced by the identity of the channel anion, which is usually F-, Cl-, or (OH)-. Density functional theory calculations have been used to determine the effect of channel anion identity on the compressibility and structure of apatite. Hydroxyapatite and fluorapatite are found to have similar zero pressure bulk moduli, of 79.2 and 82.1 GPa, respectively, while chlorapatite is considerably more compressible, with K 0 = 55.0 GPa. While the space groups of hydroxyapatite and fluorapatite do not change between 0 and 25 GPa, symmetrization of the Cl- site in chlorapatite at 7.5 GPa causes the space group to change from P2 1 /b to P6 3 /m. Examination of the valence electron density distribution in chlorapatite reveals that this symmetry change is associated with a change in the coordination of the Cl- anion from threefold to sixfold coordinated by Ca. We also calculate the pressure at which apatite decomposes to form tuite, a calcium orthophosphate mineral, and find that the transition pressure is sensitive to the identity of the channel anion, being lowest for fluorapatite (13.8 GPa) and highest for chlorapatite (26.9 GPa). Calculations are also performed within the DFT-D2 framework to investigate the influence of dispersion forces on the compressibility of apatite minerals.

The results of the structural dynamic investigation of two sevenstory reinforced concrete frame structures are presented here. The structures are both Holiday Inn rnotor hotels that are essentially identical: one is locrted about 13 miles and the other about 26 miles from the epicenter of the February 9, 1971, San Fernando earthquake. Appreciable nonstructural damage as well as some structural damage was observed. Strong-motion seismic records were obtained for the roof, intermediate story, and ground floor of each structure. The analyses are based on data from the structural drawings, architectural drawings, photographs, engineering reports, and seisrnogram records obtained before, during,more » and after the San Fernando earthquake. Both structures experienced motion well beyond the limits of the building code design criteria. A change in fundamental period was observed for each structure after several seconds of response to the earthquake, which indicated nonlinear response. The analyses indicated that the elastic capacity of some structural members was exceeded. Idealized linear models were constructed to approximate response at various time segments. A method for approximating the nonlinear response of each structure is presented. The effects of nonstructural elements, yielding beams, and column capacities are illustrated. Comparisons of the two buildings are made for ductility factors, dynarnic response characteristics, and damage. Conclusions are drawn concerning the effects of the earthquake on the structures and the future capacities of the structures. (auth)« less

Preschoolers' use of spatiotemporal history, appearance, and proper name in determining individual identity.

Gutheil, Grant; Gelman, Susan A; Klein, Eileen; Michos, Katherine; Kelaita, Kara

2008-04-01

Humans construe their environment as composed largely of discrete individuals, which are also members of kinds (e.g., trees, cars, and people). On what basis do young children determine individual identity? How important are featural properties (e.g., physical appearance, name) relative to spatiotemporal history? Two studies examined the relative importance of these factors in preschoolers' and adults' identity judgments. Participants were shown pairs of individuals who looked identical but differed in their spatiotemporal history (e.g., two physically distinct but identical Winnie-the-Pooh dolls), and were asked whether both members in the pair would have access to knowledge that had been supplied to only one of the pairs. The results provide clear support for spatiotemporal history as the primary basis of identity judgments in both preschoolers and adults, and further place issues of identity within the broader cognitive framework of psychological essentialism.

Social Identities as Pathways into and out of Addiction.

PubMed

Dingle, Genevieve A; Cruwys, Tegan; Frings, Daniel

2015-01-01

There exists a predominant identity loss and "redemption" narrative in the addiction literature describing how individuals move from a "substance user" identity to a "recovery" identity. However, other identity related pathways influencing onset, treatment seeking and recovery may exist, and the process through which social identities unrelated to substance use change over time is not well understood. This study was designed to provide a richer understanding of such social identities processes. Semi-structured interviews were conducted with 21 adults residing in a drug and alcohol therapeutic community (TC) and thematic analysis revealed two distinct identity-related pathways leading into and out of addiction. Some individuals experienced a loss of valued identities during addiction onset that were later renewed during recovery (consistent with the existing redemption narrative). However, a distinct identity gain pathway emerged for socially isolated individuals, who described the onset of their addiction in terms of a new valued social identity. Almost all participants described their TC experience in terms of belonging to a recovery community. Participants on the identity loss pathway aimed to renew their pre-addiction identities after treatment while those on the identity gain pathway aimed to build aspirational new identities involving study, work, or family roles. These findings help to explain how social factors are implicated in the course of addiction, and may act as either motivations for or barriers to recovery. The qualitative analysis yielded a testable model for future research in other samples and settings.

Microglia, the brain's resident macrophages, are dynamic CNS custodians with surprising origins in the extra-embryonic yolk sac. The consequences of their distinct ontogeny are unknown but critical to understanding and treating brain diseases. We created a brain macrophage transplantation system to disentangle how environment and ontogeny specify microglial identity. We find that donor cells extensively engraft in the CNS of microglia-deficient mice, and even after exposure to a cell culture environment, microglia fully regain their identity when returned to the CNS. Though transplanted macrophages from multiple tissues can express microglial genes in the brain, only those of yolk-sac origin fully attain microglial identity. Transplanted macrophages of inappropriate origin, including primary human cells in a humanized host, express disease-associated genes and specific ontogeny markers. Through brain macrophage transplantation, we discover new principles of microglial identity that have broad applications to the study of disease and development of myeloid cell therapies.

While the prevalence of sexual identities and behaviors of men who have sex with men (MSM) varies across countries, no study has examined country-level structural stigma toward sexual minorities as a correlate of this variation. Drawing on emerging support for the context-dependent nature of MSM's open sexual self-identification cross-nationally, we examined country-level structural stigma as a key correlate of the geographic variation in MSM's sexual attraction, behavior, and identity, and concordance across these factors. Data come from the European MSM Internet Survey, a multi-national dataset containing a multi-component assessment of sexual orientation administered across 38 European countries (N = 174,209). Country-level stigma was assessed using a combination of national laws and policies affecting sexual minorities and a measure of attitudes toward sexual minorities held by the citizens of each country. Results demonstrate that in more stigmatizing countries, MSM were significantly more likely to report bisexual/heterosexual attractions, behaviors, and identities, and significantly less likely to report concordance across these factors, than in less stigmatizing countries. Settlement size moderated associations between country-level structural stigma and odds of bisexual/heterosexual attraction and behavior, such that MSM living in sparsely populated locales within high-structural stigma countries were the most likely to report bisexual or heterosexual behaviors and attractions. While previous research has demonstrated associations between structural stigma and adverse physical and mental health outcomes among sexual minorities, this study was the first to show that structural stigma was also a key correlate not only of sexual orientation identification, but also of MSM's sexual behavior and even attraction. Findings have implications for understanding the ontology of MSM's sexuality and suggest that a comprehensive picture of MSM's sexuality will come

Age-related differences in moral identity across adulthood.

2016-06-01

In this study, age-related differences in adults' moral identity were investigated. Moral identity was conceptualized a context-dependent self-structure that becomes differentiated and (re)integrated in the course of development and that involves a broad range of value-orientations. Based on a cross-sectional sample of 252 participants aged 14 to 65 years (148 women, M = 33.5 years, SD = 16.9) and a modification of the Good Self-Assessment, it was demonstrated that mean-level of moral identity (averaged across the contexts of family, school/work, and community) significantly increased in the adult years, whereas cross-context differentiation showed a nonlinear trend peaking at the age of 25 years. Value-orientations that define individuals' moral identity shifted so that self-direction and rule-conformity became more important with age. Age-related differences in moral identity were associated with, but not fully attributable to changes in personality traits. Overall, findings suggest that moral identity development is a lifelong process that starts in adolescence but expands well into middle age.

'THEY LIGHT THE CHRISTMAS TREE IN OUR TOWN': Reflections on Identity, Gender, and Adolescent Sports.

PubMed

Miller, Kathleen E

2009-12-01

Sport occupies a prominent space in the public lives and private identities of US adolescents. Using the retrospective reflections of college students, this analysis explores two questions about sport-related identities during high school: Are 'athletes' and 'jocks' distinctly separate identities? Are these identities explicitly gendered? In four gender-segregated focus groups conducted in early 2005, 32 student-athletes from two upstate New York colleges discussed their high school experiences of sport, status, gender, and identity. Three primary themes developed with regard to differences between the 'jock' and 'athlete' archetypes: academic focus, teamwork, and cockiness/aggression. Examining the intersection of gender, high-status/high-profile sport, and identity in both popular cultural imagery and the personal experiences of the focus group discussants provided support for the thesis of a 'toxic jock' phenomenon.

Outgassing of Out-of-Autoclave Composite Primary Structures for Small Satellites

NASA Astrophysics Data System (ADS)

Komus, Alastair

Out-of-autoclave vacuum-bagged-only (VBO) processing is capable of producing lower cost composite primary structures for small satellites than autoclave processing. However, the outgassing performance of VBO structures in a vacuum environment has not been examined. Panels were manufactured from CYCOM 5320-1 and TC275-1 carbon fiber/epoxy prepreg using VBO processing. The humidity level, pre-cure dwell time, and cure cycle parameters were varied during manufacturing. The degree of cure and glass transition temperature were shown to increase with increasing oven temperature. Processing humidity levels and the length of pre-cure dwell times had no discernable effect on the total mass loss (TML) and collected volatile condensable material (CVCM) that were outgassed under vacuum. Instead the TML was controlled by moisture saturation after manufacturing. Fourier transform infrared spectroscopy showed that epoxy oligomers were the primary CVCM. The study showed the VBO laminates had outgassing values that were comparable to the autoclave-cured laminates.

Tanti, Chris; Stukas, Arthur A; Halloran, Michael J; Foddy, Margaret

2011-06-01

This study investigated the proposition that adolescence involves significant shifts in social identity as a function of changes in social context and cognitive style. Using an experimental design, we primed either peer or gender identity with a sample of 380 early- (12-13 years), mid- (15-16 years), and late-adolescents (18-20 years) and then measured the effect of the prime on self-stereotyping and ingroup favouritism. The findings showed significant differences in social identity across adolescent groups, in that social identity effects were relatively strong in early- and late-adolescents, particularly when peer group identity rather than gender identity was salient. While these effects were consistent with the experience of change in educational social context, differences in cognitive style were only weakly related to ingroup favouritism. The implications of the findings for theory and future research on social identity during adolescence are discussed. Crown Copyright © 2010. Published by Elsevier Ltd. All rights reserved.

Comparative Associations Between Achieved Bicultural Identity, Achieved Ego Identity, and Achieved Religious Identity and Adaptation Among Australian Adolescent Muslims.

2018-04-01

This study examined the comparative roles of biculturalism, ego identity, and religious identity in the adaptation of Australian adolescent Muslims. A total of 504 high school Muslim students studying at high schools in metropolitan Sydney and Melbourne, Australia, took part in this study which required them to complete a self-report questionnaire. Analyses indicated that adolescent Muslims' achieved religious identity seems to play a more important role in shaping their psychological and socio-cultural adaptation compared to adolescents' achieved bicultural identity. Adolescents' achieved ego identity tended also to play a greater role in their psychological and socio-cultural adaptation than achieved bicultural identity. The relationships between the three identities and negative indicators of psychological adaptation were consistently indifferent. Based on these findings, we propose that the three identity-based forces-bicultural identity development, religious identity attainment, and ego identity formation-be amalgamated into one framework in order for researchers to more accurately examine the adaptation of Australian adolescent Muslims.

Beliefs About the Causal Structure of the Self-Concept Determine Which Changes Disrupt Personal Identity.

PubMed

Chen, Stephanie Y; Urminsky, Oleg; Bartels, Daniel M

2016-10-01

Personal identity is an important determinant of behavior, yet how people mentally represent their self-concepts and their concepts of other people is not well understood. In the current studies, we examined the age-old question of what makes people who they are. We propose a novel approach to identity that suggests that the answer lies in people's beliefs about how the features of identity (e.g., memories, moral qualities, personality traits) are causally related to each other. We examined the impact of the causal centrality of a feature, a key determinant of the extent to which a feature defines a concept, on judgments of identity continuity. We found support for this approach in three experiments using both measured and manipulated causal centrality. For judgments both of one's self and of others, we found that some features are perceived to be more causally central than others and that changes in such causally central features are believed to be more disruptive to identity.

Professional identity is a key issue spanning the entirety of teachers’ career development. Despite the abundance of existing research examining professional identity, its link with occupation-related behavior at the primary career stage (i.e., GPA in preservice education) and the potential process that underlies this association is still not fully understood. This study explored the professional identity of Chinese preservice teachers, and its links with task value belief, intrinsic learning motivation, extrinsic learning motivation, and performance in the education program. Grade-point average (GPA) of courses (both subject and pedagogy courses) was examined as an indicator of performance, and questionnaires were used to measure the remaining variables. Data from 606 preservice teachers in the first 3 years of a teacher-training program indicated that: (1) variables in this research were all significantly correlated with each other, except the correlation between intrinsic learning motivation and program performance; (2) professional identity was positively linked to task value belief, intrinsic and extrinsic learning motivations, and program performance in a structural equation model (SEM); (3) task value belief was positively linked to intrinsic and extrinsic learning motivation; (4) higher extrinsic (but not intrinsic) learning motivation was associated with increased program performance; and (5) task value belief and extrinsic learning motivation were significant mediators in the model.

Swiss identity smells like chocolate: Social identity shapes olfactory judgments

2016-01-01

There is extensive evidence that social identities can shape people’s attitudes and behavior, but what about sensory judgments? We examined the possibility that social identity concerns may also shape the judgment of non-social properties—namely, olfactory judgment. In two experiments, we presented Swiss and non-Swiss participants with the odor of chocolate, for which Switzerland is world-famous, and a control odor (popcorn). Swiss participants primed with Swiss identity reported the odor of chocolate (but not popcorn) as more intense than non-Swiss participants (Experiments 1 and 2) and than Swiss participants primed with individual identity or not primed (Experiment 2). The self-reported intensity of chocolate smell tended to increase as identity accessibility increased—but only among Swiss participants (Experiment 1). These results suggest that identity priming can counter-act classic sensory habituation effects, allowing identity-relevant smells to maintain their intensity after repeated presentations. This suggests that social identity dynamically influences sensory judgment. We discuss the potential implications for models of social identity and chemosensory perception. PMID:27725715

The Patient-Centered Medical Home (PCMH), a popular model for primary care reorganization, includes several structural capabilities intended to enhance quality of care. The extent to which different types of primary care practices have adopted these capabilities has not been previously studied. To measure the prevalence of recommended structural capabilities among primary care practices and to determine whether prevalence varies among practices of different size (number of physicians) and administrative affiliation with networks of practices. Cross-sectional analysis. One physician chosen at random from each of 412 primary care practices in Massachusetts was surveyed about practice capabilities during 2007. Practice size and network affiliation were obtained from an existing database. Presence of 13 structural capabilities representing 4 domains relevant to quality: patient assistance and reminders, culture of quality, enhanced access, and electronic health records (EHRs). Three hundred eight (75%) physicians responded, representing practices with a median size of 4 physicians (range 2-74). Among these practices, 64% were affiliated with 1 of 9 networks. The prevalence of surveyed capabilities ranged from 24% to 88%. Larger practice size was associated with higher prevalence for 9 of the 13 capabilities spanning all 4 domains (P < 0.05). Network affiliation was associated with higher prevalence of 5 capabilities (P < 0.05) in 3 domains. Associations were not substantively altered by statistical adjustment for other practice characteristics. Larger and network-affiliated primary care practices are more likely than smaller, non-affiliated practices to have adopted several recommended capabilities. In order to achieve PCMH designation, smaller non-affiliated practices may require the greatest investments.

Students' understanding of primary and secondary protein structure: drawing secondary protein structure reveals student understanding better than simple recognition of structures.

PubMed

Harle, Marissa; Towns, Marcy H

2013-01-01

The interdisciplinary nature of biochemistry courses requires students to use both chemistry and biology knowledge to understand biochemical concepts. Research that has focused on external representations in biochemistry has uncovered student difficulties in comprehending and interpreting external representations in addition to a fragmented understanding of fundamental biochemistry concepts. This project focuses on students' understanding of primary and secondary protein structure and drawings (representations) of hydrogen-bonding in alpha helices and beta sheets. Analysis demonstrated that students can recognize and identify primary protein structure concepts when given a polypeptide. However, when asked to draw alpha helices and beta sheets and explain the role of hydrogen bonding their drawings students exhibited a fragmented understanding that lacked coherence. Faculty are encouraged to have students draw molecular level representations to make their mental models more explicit, complete, and coherent. This is in contrast to recognition and identification tasks, which do not adequately probe mental models and molecular level understanding. © 2013 by The International Union of Biochemistry and Molecular Biology.

In this study, we aimed to reveal a novel risk index as a structural risk marker for primary spontanoeus pneumothorax using body mass index and chest height, structural risk factors for pneumothorax development. Records of 86 cases admitted between February 2014 and January 2015 with or without primary spontaneous pneumothorax were analysed retrospectively. The patients were allocated to two groups as Group I and Group II. The patients were evaluated with regard to age, gender, pneumothorax side, duration of hospital stay, treatment type, recurrence, chest height and transverse diameter on posteroanterior chest graphy and body mass index. Body mass index ratio per cm of chest height was calculated by dividing body mass index with chest height. We named this risk index ratio which is defined first as 'Ankara Numune Risk Index'. Diagnostic value of Ankara Numune Risk Index value for prediction of primary spontaneous pneumothorax development was analysed with Receiver Operating Characteristics curver. Of 86 patients, 69 (80.2%) were male and 17 (19.8%) were female. Each group was composed of 43 (50%) patients. When Receiver Operating Characteristics curve analysis was done for optimal limit value 0.74 of Ankara Numune Risk Index determined for prediction of pneumothorax development risk, area under the curve was 0.925 (95% Cl, 0.872-0.977, p < 0.001). Ankara Numune Risk Index is one of the structural risk factors for prediction of primary spontaneous pneumothorax development however it is insufficient for determining recurrence. Copyright © 2015.

2016-09-20

Toll-like receptor (TLR) 4 is an important polysaccharide receptor; however, the relationships between the structures and biological activities of TLR4 and polysaccharides remain unknown. Many recent findings have revealed the primary structure of TLR4/MD-2-related polysaccharides, and several three-dimensional structure models of polysaccharide-binding proteins have been reported; and these models provide insights into the mechanisms through which polysaccharides interact with TLR4. In this review, we first discuss the origins of polysaccharides related to TLR4, including polysaccharides from higher plants, fungi, bacteria, algae, and animals. We then briefly describe the glucosidic bond types of TLR4-related heteroglycans and homoglycans and describe the typical molecular weights of TLR4-related polysaccharides. The primary structures and activity relationships of polysaccharides with TLR4/MD-2 are also discussed. Finally, based on the existing interaction models of LPS with TLR4/MD-2 and linear polysaccharides with proteins, we provide insights into the possible interaction models of polysaccharide ligands with TLR4/MD-2. To our knowledge, this review is the first to summarize the primary structures and activity relationships of TLR4-related polysaccharides and the possible mechanisms of interaction for TLR4 and TLR4-related polysaccharides.

2017-03-01

To determine if changing electronic health record (EHR) note templates can increase documentation of gender identity in an adolescent and young adult clinic. A two-step gender question was added to EHR note templates for physicals in February 2016. A retrospective chart review was performed 3 months before and after this addition. The primary measure was whether answers to the two-step question were documented. Gender identity/birth-assigned sex discordance, age, and use of the appropriate note template post-template change were also measured. One hundred twenty-five pretemplate change and 106 post-template change physicals were reviewed with an inter-rater reliability of 97%. Documentation of answers to the two-step gender identity question increased from 11% to 84% (p < .001). This study suggests that incorporating a standardized question into EHR note templates is effective at improving the documentation of gender identity in youth presenting for annual physicals.

Structural design of a large deformable primary mirror for a space telescope

NASA Astrophysics Data System (ADS)

Hansen, J. G. R.

A 4 meter aperture deformable primary mirror is designed with the mirror and its supports integrated into a single structure. The integrated active mirror's minimal weight makes it desirable for a space telescope as well as a terrestrial application. Utilizing displacement actuators, the active controls at the mirror's surface include position control and slope control in both the radial and tangential directions at each of the 40 control points. Influence functions for each of the controls are nearly independent, reducing the complexity of the control system. Experiments with breadboard models verify the structural concept and the techniques used in the finite element method of computer structural analysis. The majority of this paper is a description of finite element analysis results. Localization of influence functions is exhaustively treated. For gravity loads, a thermal gradient through the mirror thickness, and a uniform thermal soak, diffraction limited performance of the 4m design is evaluated. Loads are applied to defocus the mirror and to cause fourth-order astigmatism. Mirror scallop, instigated by a focus shift, has been virtually eliminated with the 40-actuator design. The structural concept is so effective that it should be considered for uncontrolled primary mirrors as well as active mirrors.

Metabolic and structural integrity of magnetic nanoparticle-loaded primary endothelial cells for targeted cell therapy.

To successfully translate magnetically mediated cell targeting from bench to bedside, there is a need to systematically assess the potential adverse effects of magnetic nanoparticles (MNPs) interacting with 'therapeutic' cells. Here, we examined in detail the effects of internalized polymeric MNPs on primary rat endothelial cells' structural intactness, metabolic integrity and proliferation potential. The intactness of cytoskeleton and organelles was studied by fluorescent confocal microscopy, flow cytometry and high-resolution respirometry. MNP-loaded primary endothelial cells preserve intact cytoskeleton and organelles, maintain normal rate of proliferation, calcium signaling and mitochondria energy metabolism. This study provides supportive evidence that MNPs at doses necessary for targeting did not induce significant adverse effects on structural integrity and functionality of primary endothelial cells - potential cell therapy vectors.

Collective school-type identity: predicting students' motivation beyond academic self-concept.

PubMed

Knigge, Michel; Hannover, Bettina

2011-06-01

In Germany, according to their prior achievement students are tracked into different types of secondary school that provide profoundly different options for their future educational careers. In this paper we suggest that as a result, school tracks clearly differ in their social status or reputation. This should translate into different collective school-type identities for their students, irrespective of the students' personal academic self-concepts. We examine the extent to which collective school-type identity systematically varies as a function of the school track students are enrolled in, and the extent to which students' collective school-type identity makes a unique contribution beyond academic self-concept and school track in predicting scholastic motivation. In two cross-sectional studies a measure of collective school-type identity is established and applied to explain motivational differences between two school tracks in Berlin. In Study 1 (N = 39 students) the content of the collective school-type identity is explored by means of an open format questionnaire. Based on these findings a structured instrument (semantic differential) to measure collective school-type identity is developed. In Study 2 (N = 1278 students) the assumed structure with four subscales (Stereotype Achievement, Stereotype Motivation, Stereotype Social, and Compensation) is proved with confirmatory factor analysis. This measure is used to compare the collective school-type identity across school tracks and predict motivational outcomes. Results show large differences in collective school-type identity between students of different school tracks. Furthermore, these differences can explain motivational differences between school tracks. Collective school-type identity has incremental predictive power for scholastic motivation, over and above the effects of academic self-concept and school track.

Subjective adult identity and casual sexual behavior.

A majority of Americans have a casual sexual experience before transitioning to adulthood. Little research has yet to examine how identity influences causal sexual behavior. The current study fills this gap in the literature by examining if subjective adult identity predicts casual sexual behavior net of life course transitions in a national sample of Americans. To answer this research question, the Longitudinal Study of Adolescent to Adult Health is utilized. Structural equation modeling results show the older and more adult-like individuals feel the less likely they are to report a recent casual sexual partner. Once life course factors are included in the model, subjective identity is no longer associated with casual sex. Practitioners who work with adult populations need to consider how life course transitions influence casual sexual behavior.

Identity and collective action among European Kurds.

This research investigated the role of group-based anger and efficacy in explaining the effects of subgroup (ethnic) and common (European) identity on collective action among Kurds in Europe responding to different types of disadvantage. Whereas stronger Kurdish identity positively predicted intentions for collective action (mediated by anger and efficacy), stronger common ingroup identity was negatively related to collective action intentions. This effect occurred primarily when structural disadvantage was salient, not when attention was drawn to a specific incident of disadvantage, and was mediated by anger but not efficacy. The findings complement recent work demonstrating that intergroup harmony can undermine social change, suggesting that stronger common-group identification reduces collective action by reducing minority-group members' sensitivity to potential bias against them. © 2014 The British Psychological Society.

On identity: from a philosophical point of view

PubMed Central

2013-01-01

Background The term “identity” has a much longer tradition in Western philosophy than in psychology. However, the philosophical discourse addresses very different meanings of the term, which should be distinguished to avoid misunderstandings, but also to sharpen the key meanings of the term in psychological contexts. These crucial points in the philosophical concepts of identity in the sense of singularity, individuality, or self-sameness may structure the ongoing discussion on identity in psychiatric diagnoses (as in DSM-5, Child Adolesc Psychiatry Ment, this issue, 2013), in psychology, psychoanalysis, but also neuroscience and neurophilosophy (Child Adolesc Psychiatry Ment, this issue, 2013). Method The concept of identity is subjected to a systematic philosophical analysis following some milestones in its history to provide a background for recent discussions on identity in psychiatry and psychology. Results The article focuses first on the philosophical core distinctions of identity in the different meanings to be addressed, second, briefly on some of the diverse psychological histories of the concept in the second half of the 20th century. Finally some reflections are presented on borderline personality disorder, considered as a mental disorder with a disturbance or diffusion of identity as core feature, and briefly on a newly developed instrument assessing identity development and identity diffusion in adolescence, the AIDA that is also presented in the special issue of this journal (Child Adolesc Psychiatry Ment, this issue, 2013). Conclusion As a conclusion, different points of view concerning identity are summarized in respect to treatment planning, and different levels of description of identity in phenomenology, philosophy of mind, cognitive science, and social science and personality psychology are outlined.

Strange Bedfellows: Anachronisms, Identity Politics, and the Queer Case of Trans.

2017-01-01

This article explores trans identities, as articulated within a few historical texts. From early literary depictions of gender difference, to medicalized conceptions of transsexualism, to a proliferation of trans and queer identities represented by an ever-expanding "alphabet soup" of identity labels, our understandings of identities, sexualities, and queer community-building continue to change. I use the notion of "kind-making," as elaborated on in the work of Ian Hacking, to illustrate that some queer and trans identifications are affiliative, whereas others are contrastive or oppositional in nature, and these structural differences have important implications with respect to understanding identity and sexuality, and also trans inclusion within LGBT communities and activist efforts.

Architectural and Urban Identity Transformation of Eskisehir - An Anatolian City

NASA Astrophysics Data System (ADS)

Kandemir, Ozlem

2017-10-01

City is the arena where we identify ourselves and interact with others and our environment; cities are epicentres of interaction, transition and fusion of different communities and their cultures. Thus, it is important to discuss the elements of change and their consequences in architectural - urban spaces and their products in the context of identity. Urban identity can be defined as the impression invoked on its inhabitants by the environmental, historical, sociocultural and spatial values. Both architectural and urban identity have a dynamic structure, susceptive to every change on both social and administrative structure. Both global and national economic fluctuations in the last decades and industrialisation throughout the 20th century caused dramatic and diverse changes in the conditions of life, consumption forms, the perception of time and space consequently transforming architecture and city. The changes in all the different aspects of the city life and structure with time cause transformation of architecture and urban identity. This dynamism caused by changes and new formations in the cultural life and environmental conditions also leads to transforming customs and the ways we occupy/use/live in a place. Consequently, these changes and new social norms that can transform the way we occupy a space and our demands from a place can be asserted. All new requirements caused by these new conditions of urban life transform the existing architecture and spaces. In this presentation, the transformation of the architectural and urban identity of Eskisehir will be discussed through its dynamics like architectural and urban transformation, industry and politics.

In cartilage repair, scaffold-assisted single-step techniques are used to improve the cartilage regeneration. Nevertheless, the fixation of cartilage implants represents a challenge in orthopaedics, particularly in the moist conditions that pertain during arthroscopic surgery. Within the animal kingdom a broad range of species has developed working solutions to intermittent adhesion under challenging conditions. Using a top-down approach we identified promising mechanisms for biomimetic transfer The tree-frog adhesive system served as a test case to analyze the adhesion capacity of a polyglycolic acid (PGA) scaffold with and without a structural modification in a bovine articular cartilage defect model. To this end, PGA implants were modified with a simplified foot-pad structure and evaluated on femoral articular bovine cartilage lesions. Non-structured PGA scaffolds were used as control. Both implants were pressed on 20 mm × 20 mm full-thickness femoral cartilage defects using a dynamometer. The structured scaffolds showed a higher adhesion capacity on the cartilage defect than the non-structured original scaffolds. The results suggest that the adhesion ability can be increased by means of biomimetic structured surfaces without the need of additional chemical treatment and thus significantly facilitate primary fixation procedures.

The primary cilium regulates cellular signalling including influencing wnt sensitivity by sequestering β-catenin within the ciliary compartment. Topographic regulation of intracellular actin-myosin tension can control stem cell fate of which wnt is an important mediator. We hypothesized that topography influences mesenchymal stem cell (MSC) wnt signaling through the regulation of primary cilia structure and function. MSCs cultured on grooves expressed elongated primary cilia, through reduced actin organization. siRNA inhibition of anterograde intraflagellar transport (IFT88) reduced cilia length and increased active nuclear β-catenin. Conversely, increased primary cilia assembly in MSCs cultured on the grooves was associated with decreased levels of nuclear active β-catenin, axin-2 induction and proliferation, in response to wnt3a. This negative regulation, on grooved topography, was reversed by siRNA to IFT88. This indicates that subtle regulation of IFT and associated cilia structure, tunes the wnt response controlling stem cell differentiation. PMID:24346024

Graduate education in gerontology has an essential role in providing the foundational knowledge required to work with a diverse aging population. It can also play an essential role in promoting best-practice approaches for the development of professional identity as a gerontologist. The primary goal of this study was to determine what factors predict the professional identity and career path of gerontologists. In addition, the study explored how experiential learning influenced professional identity for newcomers to the field and for those experienced in an aging-related field ("professional incumbents"). Graduates (N = 146) of Association for Gerontology in Higher Education-affiliated graduate programs participated. Professional identity as a gerontologist was predicted by length of time in the field, age, satisfaction with coworkers, and satisfaction with opportunities for advancement. Experiential learning contributed to professional identity in important but different ways for newcomers to the field and for professional incumbents. The inclusion of an academic/experiential learning model within graduate gerontology programs promotes the development of professional identity and career path for all graduate students.

The rapid cycling synchrotron (RCS) of the China Spallation Neutron Source (CSNS) is a high intensity proton ring with beam power of 100 kW. In order to control the residual activation to meet the requirements of hands-on maintenance, a two-stage collimation system has been designed for the RCS. The collimation system consists of one primary collimator made of thin metal to scatter the beam and four secondary collimators as absorbers. Thermal analysis is an important aspect in evaluating the reliability of the collimation system. The calculation of the temperature distribution and thermal stress of the primary collimator with different materials is carried out by using ANSYS code. In order to control the temperature rise and thermal stress of the primary collimator to a reasonable level, an air cooling structure is intended to be used. The mechanical design of the cooling structure is presented, and the cooling efficiency with different chin numbers and wind velocity is also analyzed. Finally, the fatigue lifetime of the collimator under thermal shocks is estimated.

This report examined ethnic identity in 367 recently diagnosed cancer patients in Hawai'i's primary ethnic groups: Japanese, Hawaiians, Europeans, and Filipinos. The study assessed ethnic self-identify; definitions of and participation in different ethnic lifestyles; and relationships between measures of ethnic self-identity, lifestyle, and other indicators of ethnic and cultural affiliations. Results indicated that medical record-based ethnic indicators were well linked to individual self-reports of family pedigree. Self-descriptors included non-standard terms such as "American" and "Local," and respondents reported following between five and six different ethnically-associated ways of life. Multivariate analysis indicated that ethnic self-identity made a unique contribution that went beyond standard ethnic and acculturative markers in explaining lifestyles. This study provides strong support for multiculturalism in this ethnically heterogeneous population.

The initiative to increase the number of students in STEM disciplines and train them for a science-related job is a current national focus. Using longitudinal panel data from a national study that followed underrepresented college students in STEM fields, we investigate the neglected role that social psychological processes play in influencing science activity among the young. We study the impact of identity processes related to being a science student on entering a science occupation. More broadly, we examine whether an identity formulated in one institutional setting (education) has effects that persist to another institutional setting (the economy). We find that the science identity positively impacts the likelihood of entering a science occupation. It also serves as a mediator for other factors that are related to educational success. This provides insight into how an identity can guide behavior to move persons into structural positions across institutional domains. PMID:28364837

Distinctive acceptor-end structure and other determinants of Escherichia coli tRNAPro identity.

PubMed Central

McClain, W H; Schneider, J; Gabriel, K

1994-01-01

The previously uncharacterized determinants of the specificity of tRNAPro for aminoacylation (tRNAPro identity) were defined by a computer comparison of all Escherichia coli tRNA sequences and tested by a functional analysis of amber suppressor tRNAs in vivo. We determined the amino acid specificity of tRNA by sequencing a suppressed protein and the aminoacylation efficiency of tRNA by examining the steady-state level of aminoacyl-tRNA. On substituting nucleotides derived from the acceptor end and variable pocket of tRNAPro for the corresponding nucleotides in a tRNAPhe gene, the identity of the resulting tRNA changed substantially but incompletely to that of tRNAPro. The redesigned tRNAPhe was weakly active and aminoacyl-tRNA was not detected. Ethyl methanesulfonate mutagenesis of the redesigned tRNAPhe gene produced a mutant with a wobble pair in place of a base pair in the end of the acceptor-stem helix of the transcribed tRNA. This mutant exhibited both a tRNAPro identity and substantial aminoacyl-tRNA. The results speak for the importance of a distinctive conformation in the acceptor-stem helix of tRNAPro for aminoacylation by the prolyl-tRNA synthetase. The anticodon also contributes to tRNAPro identity but is not necessary in vivo. Images PMID:8127693

When patients are diagnosed with cancer, they begin to negotiate their illness identity in relation to their past and future selves, their relationships, and their group memberships. Thus, how patients view their cancer in relation to their other identities may affect how and why they make particular decisions about treatment options. Using the Communication Theory of Identity (CTI), the current study explores: (1) how and why illness identity is framed across identity layers in relation to one particular cancer treatment: participation in a cancer clinical trial (CT); and (2) how and why patients experience identity conflicts while making their treatment decisions. Semi-structured, in-depth interviews were analyzed for 46 cancer patients who were offered a CT. Results of a grounded theory analysis indicated that patients expressed separate identity frames (e.g., personal, relational, and communal), aligned identity frames (e.g., personal and communal), and identity conflicts (e.g., personal-personal). This study theoretically shows how and why patient illness identity relates to cancer treatment decision-making as well as how and why patients relate (and conflict) with the cancer communal identity frame. Practical implications include how healthcare providers and family members can support patient decision-making through awareness of and accommodating to identity shifts.

Mistaken identity: activating conservative political identities induces "conservative" financial decisions.

PubMed

Morris, Michael W; Carranza, Erica; Fox, Craig R

2008-11-01

Four studies investigated whether activating a social identity can lead group members to choose options that are labeled in words associated with that identity. When political identities were made salient, Republicans (but not Democrats) became more likely to choose the gamble or investment option labeled "conservative." This shift did not occur in a condition in which the same options were unlabeled. Thus, the mechanism underlying the effect appears to be not activated identity-related values prioritizing low risk, but rather activated identity-related language (the group label "conservative"). Indeed, when political identities were salient, Republicans favored options labeled "conservative" regardless of whether the options were low or high risk. Finally, requiring participants to explain the label "conservative" before making their choice did not diminish the effect, which suggests that it does not merely reflect inattention to content or construct accessibility. We discuss the implications of these results for the literatures on identity, priming, choice, politics, and marketing.

Although much research has been conducted on goal setting, researchers have not examined goal-directedness or propensity to set goals as a stable human characteristic in adults. In this study, a survey was developed and distributed to 104 adult participants to assess their goal-directedness, personal identity, and various life outcomes. A theoretical model was developed and tested using structural equation modeling that proposed that both goal-directedness and personal identity should positivcly influence important life outcomes. Analysis showed that goal-directedness and personal identity are positively related to personal well-being, salary, and marital satisfaction. Further, personal identity was positively related to job satisfaction but, contrary to related research, goal-directedness did not predict job satisfaction.

To evaluate if the provision of clinical dental care, by means of the main curative procedures recommended in Primary Health Care, is associated with team structural characteristics, considering the presence of a minimum set of equipment, instrument, and supplies in Brazil's primary health care services. A cross-sectional exploratory study based on data collected from 18,114 primary healthcare services with dental health teams in Brazil, in 2014. The outcome was created from the confirmation of five clinical procedures performed by the dentist, accounting for the presence of minimum equipment, instrument, and supplies to carry them out. Covariables were related to structural characteristics. Poisson regression with robust variance was used to obtain crude and adjusted prevalence ratios, with 95% confidence intervals. A total of 1,190 (6.5%) dental health teams did not present the minimum equipment to provide clinical dental care and only 2,498 (14.8%) had all the instrument and supplies needed and provided the five curative procedures assessed. There was a positive association between the outcome and the composition of dental health teams, higher workload, performing analysis of health condition, and monitoring of oral health indicators. Additionally, the dental health teams that planned and programmed oral health actions with the primary care team monthly provided the procedures more frequently. Dentists with better employment status, career plans, graduation in public health or those who underwent permanent education activities provided the procedures more frequently. A relevant number of Primary Health Care services did not have the infrastructure to provide clinical dental care. However, better results were found in dental health teams with oral health technicians, with higher workload and that plan their activities, as well as in those that employed dentists with better working relationships, who had dentists with degrees in public health and who underwent

Dual identities: organizational negotiation in STEM-focused Catholic schools

2017-06-01

In the last decade, STEM-focused schools have opened their doors nationally in the hope of meeting students' contemporary educational needs. Despite the growth of these STEM-focused institutions, minimal research exists that follows how schools make a transition toward a STEM focus and what organizational structures are most conducive to a successful transition. The adoption of a STEM focus has clear implications for a school's organizational identity. For Catholic schools, the negotiation of a new STEM focus is especially complex, as Catholic schools have been shown to generally possess a distinct religious and cultural organizational identity. The adoption of a second, STEM-focused identity raises questions about whether and how these identities can coexist. Framed by perspectives on organizational identity and existing conceptualizations of the cultural and religious hallmarks of Catholic schools, this study utilizes a multiple-case study design to explore the organizational transition of four Catholic K-8 institutions to Catholic STEM-focused schools. These cases demonstrate the particular challenges of negotiating multiple organizational identities. While variation existed in how the four schools accommodated these identities, the most promising environments for successful transition drew upon an aggregative model of identity negotiation, that is, when schools attended to both identities, but ensured that the original Catholic identity of the school remained foundational to all decisions. The least successful identity negotiations occurred when there was a lack of common understanding about what comprised a STEM-focused school, leading to minimal buy-in from stakeholders or when a school sought to make the transition for recruitment or marketing rather than mission-driven reasons. Discussion of the more successful identity aggregation provides a framework for schools within and beyond the religious sector that desire to adopt an additional STEM

The purpose of this study was to examine the associations of exercise identity, exercise commitment, exercise dependence, and, particularly, the mediating effects of exercise commitment on the relationship between exercise identity and exercise dependence. 253 Taiwanese regular exercisers completed measures, including the Exercise Dependence Scale-Revised, the Exercise Identity Scale, the Exercise Commitment Scale, and the Godin Leisure Time Exercise Questionnaire. Results showed that exercise identity, exercise dependence, and two types of exercise commitment were moderately to highly correlated. Furthermore, structural equation modelling indicated that a "have to" commitment partially mediated the relationship between exercise identity and exercise dependence. Based on the mediating role of a "have to" commitment, the findings are particularly informative to exercise instructors and for exercise program managers.

Readiness for the Patient-Centered Medical Home: Structural Capabilities of Massachusetts Primary Care Practices

2008-01-01

Background The Patient-Centered Medical Home (PCMH), a popular model for primary care reorganization, includes several structural capabilities intended to enhance quality of care. The extent to which different types of primary care practices have adopted these capabilities has not been previously studied. Objective To measure the prevalence of recommended structural capabilities among primary care practices and to determine whether prevalence varies among practices of different size (number of physicians) and administrative affiliation with networks of practices. Design Cross-sectional analysis. Participants One physician chosen at random from each of 412 primary care practices in Massachusetts was surveyed about practice capabilities during 2007. Practice size and network affiliation were obtained from an existing database. Measurements Presence of 13 structural capabilities representing 4 domains relevant to quality: patient assistance and reminders, culture of quality, enhanced access, and electronic health records (EHRs). Main Results Three hundred eight (75%) physicians responded, representing practices with a median size of 4 physicians (range 2–74). Among these practices, 64% were affiliated with 1 of 9 networks. The prevalence of surveyed capabilities ranged from 24% to 88%. Larger practice size was associated with higher prevalence for 9 of the 13 capabilities spanning all 4 domains (P < 0.05). Network affiliation was associated with higher prevalence of 5 capabilities (P < 0.05) in 3 domains. Associations were not substantively altered by statistical adjustment for other practice characteristics. Conclusions Larger and network-affiliated primary care practices are more likely than smaller, non-affiliated practices to have adopted several recommended capabilities. In order to achieve PCMH designation, smaller non-affiliated practices may require the greatest investments. Electronic supplementary material The online version of this article (doi:10

Alternative Framings, Countervailing Visions: Locating the "P" in Professional Identity Formation.

PubMed

Hafferty, Frederic W; Michalec, Barret; Martimianakis, Maria Athina Tina; Tilburt, Jon C

2016-02-01

Professional identity formation in medical education is referenced increasingly as an object for educational reform. The authors introduce core concepts from two largely untapped literatures on identity and formation, contrasting framings on occupational preparation from within the organizational socialization literature with issues of socialization and professional acculturation from a military sciences perspective.The organizational sciences literature emphasizes socializing a workforce to "fit in," raising questions about how organization values might clash with core professional values concerning patient primary and social justice. The military literature, in turn, advances the notions of professional identity as a collective property, and that a particular social other (the public) must participate in shaping the group's identity as a profession.The authors extrapolate from these reviews that the training of physicians-as-professionals, and thus issues of socialization and identity formation, require intentionality and specificity around these contrasting issues. In turn, they argue that medical educators must attend to socializing trainees to a professional group identity while at the same time producing health care professionals who retain the capacity to resist the bureaucratic application of standardized solutions to contemporary problems. Educators must thus strive to identify the skills, knowledge, and attitudes necessary that will allow physicians-qua-professionals to function as a quasi-subversive work force and to disrupt the very system that helped to shape their identity, so that they may fulfill their mission to their patients.

A Dual Identity Approach for Conceptualizing and Measuring Children's Gender Identity.

Martin, Carol Lynn; Andrews, Naomi C Z; England, Dawn E; Zosuls, Kristina; Ruble, Diane N

2017-01-01

The goal was to test a new dual identity perspective on gender identity by asking children (n = 467) in three grades (M age  = 5.7, 7.6, 9.5) to consider the relation of the self to both boys and girls. This change shifted the conceptualization of gender identity from one to two dimensions, provided insights into the meaning and measurement of gender identity, and allowed for revisiting ideas about the roles of gender identity in adjustment. Using a graphical measure to allow assessment of identity in young children and cluster analyses to determine types of identity, it was found that individual and developmental differences in how similar children feel to both genders, and these variations matter for many important personal and social outcomes. © 2016 The Authors.

The Identity Mapping Project: Demographic differences in patterns of distributed identity.

PubMed

Gilbert, Richard L; Dionisio, John David N; Forney, Andrew; Dorin, Philip

2015-01-01

The advent of cloud computing and a multi-platform digital environment is giving rise to a new phase of human identity called "The Distributed Self." In this conception, aspects of the self are distributed into a variety of 2D and 3D digital personas with the capacity to reflect any number of combinations of now malleable personality traits. In this way, the source of human identity remains internal and embodied, but the expression or enactment of the self becomes increasingly external, disembodied, and distributed on demand. The Identity Mapping Project (IMP) is an interdisciplinary collaboration between psychology and computer Science designed to empirically investigate the development of distributed forms of identity. Methodologically, it collects a large database of "identity maps" - computerized graphical representations of how active someone is online and how their identity is expressed and distributed across 7 core digital domains: email, blogs/personal websites, social networks, online forums, online dating sites, character based digital games, and virtual worlds. The current paper reports on gender and age differences in online identity based on an initial database of distributed identity profiles.

Purification and structural characterization of vasoactive intestinal polypeptide from the trout and bowfin.

Wang, Y; Conlon, J M

1995-04-01

Vasoactive intestinal polypeptide (VIP) was purified from extracts of the stomachs of the rainbow trout, Oncorhynchus mykiss, and the bowfin, Amia calva. The primary structure of VIP from both species was the same: His-Ser-Asp-Ala-Ile-Phe-Thr-Asp-Asn-Tyr10- Ser-Arg-Phe-Arg-Lys-Gln-Met-Ala-Val-Lys20-Lys-Tyr-Leu-Asn-Ser-Val- Leu-Thr. This amino acid sequence shows only one amino acid substitution (Val5-->Ile) compared with the common sequence of VIP from the chicken, alligator, and European green frog. The structural identity of VIP from the trout and bowfin is consistent with the close phylogenetic relationship between the Salmoniformes and the Amiiformes and the data indicate that pressure to conserve the complete primary structure of VIP during vertebrate evolution has been very strong.

Psychiatric comorbidity of gender identity disorders: a survey among Dutch psychiatrists.

2003-07-01

In the Netherlands, it is considered good medical practice to offer patients with gender identity disorder the option to undergo hormonal and surgical sex reassignment therapy. A liberalization of treatment guidelines now allows for such treatment to be started at puberty or prepuberty. The question arises as to what extent gender identity disorder can be reliably distinguished from a cross-gender identification that is secondary to other psychiatric disorders. The authors sent survey questionnaires to 382 board-certified Dutch psychiatrists regarding their experiences with diagnosing and treating patients with gender identity disorder. One hundred eighty-six psychiatrists responded to the survey. These respondents reported on 584 patients with cross-gender identification. In 225 patients (39%), gender identity disorder was regarded as the primary diagnosis. For the remaining 359 patients (61%), cross-gender identification was comorbid with other psychiatric disorders. In 270 (75%) of these 359 patients, cross-gender identification was interpreted as an epiphenomenon of other psychiatric illnesses, notably personality, mood, dissociative, and psychotic disorders. These data suggest that there is little consensus, at least among Dutch psychiatrists, about diagnostic features of gender identity disorder or about the minimum age at which sex reassignment therapy is a safe option. Therapy options proposed to patients with gender identity disorder appear to depend on personal preferences of psychiatrists. These results underline the need for more specific diagnostic rules in this area.

Purpose/Objectives To examine ethnic identity and sociodemographic factors in minority patients' perceptions of healthcare discrimination in breast cancer care. Design Mixed methods. Setting Participants' homes in the metropolitan areas of Phoenix and Tucson, AZ. Sample 39 women treated for breast cancer in the past six years: 15 monolingual Spanish-speaking Latinas, 15 English-speaking Latinas, and 9 African Americans. Methods Two questionnaires were administered. Individual interviews with participants were conducted by nurse researchers. Quantitative, qualitative, and matrix analytic methods were used. Main Research Variables Ethnic identity and perceptions of discrimination. Findings Eighteen women (46%) believed race and spoken language affected the quality of health care. Perceived disrespect from providers was attributed to participant's skin color, income level, citizenship status, and ability to speak English. Discrimination was more likely to be described in a primary care context, rather than cancer care. Ethnic identity and early-stage breast cancer diagnosis were the only study variables significantly associated with perceived healthcare discrimination. Conclusions This article describes the first investigation examining ethnic identity and perceived discrimination in cancer care delivery. Replication of this study with larger samples is needed to better understand the role of ethnic identity and cancer stage in perceptions of cancer care delivery. Implications for Nursing Identification of ethnic-specific factors that influence patient's perspectives and healthcare needs will facilitate development of more effective strategies for the delivery of cross-cultural patient-centered cancer care.

SuperIdentity: Fusion of Identity across Real and Cyber Domains

DOE Office of Scientific and Technical Information (OSTI.GOV)

Black, Sue; Creese, Sadie; Guest, Richard

Under both benign and malign circumstances, people now manage a spectrum of identities across both real-world and cyber domains. Our belief, however, is that all these instances ultimately track back for an individual to reflect a single 'SuperIdentity'. This paper outlines the assumptions underpinning the SuperIdentity Project, describing the innovative use of data fusion to incorporate novel real-world and cyber cues into a rich framework appropriate for modern identity. The proposed combinatorial model will support a robust identification or authentication decision, with confidence indexed both by the level of trust in data provenance, and the diagnosticity of the identity factorsmore » being used. Additionally, the exploration of correlations between factors may underpin the more intelligent use of identity information so that known information may be used to predict previously hidden information. With modern living supporting the 'distribution of identity' across real and cyber domains, and with criminal elements operating in increasingly sophisticated ways in the hinterland between the two, this approach is suggested as a way forwards, and is discussed in terms of its impact on privacy, security, and the detection of threat.« less

2015-12-01

Adopted Korean adolescents face the task of grappling with their identity as Koreans and coming to terms with their adoptive status. In order to explore these dual identities, the authors conducted a person-centered study of the identity profiles of 189 adopted Korean American adolescents. Using cluster analytic procedures, the study examined patterns of commitment to ethnic and adoptive identities, revealing six conceptually unique identity clusters. Analyzing the association between these identity profiles and psychological adjustment, the study found that the identity profiles were undifferentiated with respect to behavioral development and risk behaviors. However, group differences were found on life satisfaction, school adjustment, and family functioning. Results confirm the importance of considering the collective impact of multiple social identities on a variety of outcomes. The social implications of the results are discussed. © 2015 Wiley Periodicals, Inc.

Men who have sex with men (MSM) remain at high risk for HIV infection. Culturally specific sexual identities, encompassing sexual roles, behavior, and appearance, may shape MSM's experiences of stigmatization and discrimination, and affect their vulnerability to HIV. This multi-site qualitative study (n = 363) encompassing 31 focus group discussions (FGDs) and 121 in-depth interviews (IDIs) across 15 sites in India investigated sexual identity formation, identity practices, and transitions and their implications for HIV prevention. IDIs and FGDs were transcribed, translated, and underwent thematic analysis. Our findings document heterogeneous sexual identity formation, with MSM who have more gender nonconforming behaviors or appearance reporting greater family- and community-level disapproval, harassment, violence, and exclusion. Concealing feminine aspects of sexual identities was important in daily life, especially for married MSM. Some participants negotiated their identity practices in accordance with socioeconomic and cultural pressures, including taking on identity characteristics to suit consumer demand in sex work and on extended periods of joining communities of hijras (sometimes called TG or transgender women). Participants also reported that some MSM transition toward more feminine and hijra or transgender women identities, motivated by intersecting desires for feminine gender expression and by social exclusion and economic marginalization. Future studies should collect information on gender nonconformity stigma, and any changes in sexual identity practices or plans for transitions to other identities over time, in relation to HIV risk behaviors and outcomes.

Role transition in primary care settings.

PubMed

Holt, Ian G S

2008-01-01

This paper reports on research that explored how nurses who are engaged in advanced practice adapt and adjust to their roles in primary and community health settings. Successive government policy has highlighted how the changing roles of nurses, who are engaged in advanced practice, are crucial to delivering high-quality patient care. The paper offers a framework for role transition which is potentially generalisable to doctors, physiotherapists and other healthcare professionals. The aim of the study was to enable an understanding of role transition, from a study of nurses going through changes to their roles or moving to new roles. The intended purpose of the study was to explore what was going on within role transition, and considers by what process(es) role transition evolves or is experienced. Eleven nurses' actions, expectations, and experiences of role transition were explored, within three district nurse centres and two community NHS trusts. Data were collected from participant and non-participant observation, content analysis of job descriptions and from individual and group interviews, including semi-structured schedules and focus group techniques. Data were comparatively analysed to conceptualise and saturate core themes, which were discussed and developed with participants and healthcare managers. A theory of role transition is proposed through a model representing the 'who', 'what', 'where' and 'how' of role transition, through four concepts of centring identity(ies); focusing role(s); enacting role(s); and shaping role(s). Identity was regarded by the participants as being the role, the person, and as part of a group. Current and anticipated role foci directed enactment of role within given contexts and resources, while shaping of role involved a balance of role loss and role expansion. This article presents a theory of role transition for primary care professionals.

A longitudinal integration of identity styles and educational identity processes in adolescence.

Identity formation is a main adolescent psychosocial developmental task. The complex interconnection between different processes that are at the basis of one's identity is a research and applied intervention priority. In this context, the identity style model focuses on social-cognitive strategies (i.e., informational, normative, and diffuse-avoidant) that individuals can use to deal with identity formation. The 3-factor identity dimensional model examines the interplay between identity processes of commitment, in-depth exploration, and reconsideration of commitment in different life domains. Theoretical integrations between these models have been proposed, but there is a dearth of studies unraveling their longitudinal links in specific identity domains. We addressed this gap by testing in a 3-wave longitudinal study the bidirectional associations between identity styles and educational identity processes measured during 1 academic year. Participants were 1,151 adolescents (58.7% female). Results highlighted that the informational style was related over time to higher levels of educational commitment and in-depth exploration, whereas the diffuse-avoidant style was related to lower levels of commitment and higher levels of reconsideration of commitment. Educational commitment was positively related to the informational and normative styles; in-depth exploration was positively related to the informational style; and reconsideration of commitment was positively related to the diffuse-avoidant style. These relations were not moderated by adolescents' gender and age. Hence, identity styles and educational identity processes reinforce each other during 1 academic year. Theoretical integrations between these models, suggestions for integration with other identity approaches (e.g., narrative identity models), and practical implications are discussed.

In the revision of the Diagnostic and Statistical Manual (DSM-5), "Identity" is an essential diagnostic criterion for personality disorders (self-related personality functioning) in the alternative approach to the diagnosis of personality disorders in Section III of DSM-5. Integrating a broad range of established identity concepts, AIDA (Assessment of Identity Development in Adolescence) is a new questionnaire to assess pathology-related identity development in healthy and disturbed adolescents aged 12 to 18 years. Aim of the present study is to investigate differences in identity development between adolescents with different psychiatric diagnoses. Participants were 86 adolescent psychiatric in- and outpatients aged 12 to 18 years. The test set includes the questionnaire AIDA and two semi-structured psychiatric interviews (SCID-II, K-DIPS). The patients were assigned to three diagnostic groups (personality disorders, internalizing disorders, externalizing disorders). Differences were analyzed by multivariate analysis of variance MANOVA. In line with our hypotheses, patients with personality disorders showed the highest scores in all AIDA scales with T>70. Patients with externalizing disorders showed scores in an average range compared to population norms, while patients with internalizing disorders lay in between with scores around T=60. The AIDA total score was highly significant between the groups with a remarkable effect size of f= 0.44. Impairment of identity development differs between adolescent patients with different forms of mental disorders. The AIDA questionnaire is able to discriminate between these groups. This may help to improve assessment and treatment of adolescents with severe psychiatric problems.

Western publicly funded health care systems increasingly rely on interdisciplinary teams to support primary care delivery and management of chronic conditions. This knowledge synthesis focuses on what is known in the academic and grey literature about optimal structural characteristics of teams. Its goal is to assess which factors contribute to the effective functioning of interdisciplinary primary care teams and improved health system outcomes, with specific focus on (i) team structure contribution to team process, (ii) team process contribution to primary care goals, and (iii) team structure contribution to primary care goals. The systematic search of academic literature focuses on four chronic conditions and co-morbidities. Within this scope, qualitative and quantitative studies that assess the effects of team characteristics (funding, governance, organization) on care process and patient outcomes will be searched. Electronic databases (Ovid MEDLINE, Embase, CINAHL, PAIS, Web of Science) will be searched systematically. Online web-based searches will be supported by the Grey Matters Tool. Studies will be included, if they report on interdisciplinary primary care in publicly funded Western health systems, and address the relationships between team structure, process, and/or patient outcomes. Studies will be selected in a three-stage screening process (title/abstract/full text) by two independent reviewers in each stage. Study quality will be assessed using the Mixed Methods Assessment Tool. An a priori framework will be applied to data extraction, and a narrative framework approach is used for the synthesis. Using an integrated knowledge translation approach, an electronic decision support tool will be developed for decision makers. It will be searchable along two axes of inquiry: (i) what primary care goals are supported by specific team characteristics and (ii) how should teams be structured to support specific primary care goals?

'Everyone here wants everyone else to get better': The role of social identity in eating disorder recovery.

PubMed

McNamara, Niamh; Parsons, Harriet

2016-12-01

Retention of a positively valued illness identity contributes to poor outcomes for individuals with eating disorders (EDs). Consequently, dis-identification from the illness identity and the adoption of a recovery identity are vital for successful recovery. While social identity processes have been shown to influence ED maintenance, their role in recovery is rarely considered. This study explores how a sense of shared identity helps individuals with EDs manage their condition and promotes recovery. Transcripts from 18 online support sessions involving 75 participants were thematically analysed. Our findings suggest that the illness identity initially operates as a social identity that forms the basis for connections with similar others. For those wishing to recover, identity-based support is then perceived to be more effective than that found outside the group. Online interactions also facilitate construction of a new shared recovery identity which promotes a shift from the illness identity as a primary source of definition and endorses group norms of illness disclosure and treatment engagement. While in the clinical literature, ED identity is seen as problematic and interventions are targeted at challenging an individual's self-concept, we suggest that interventions could instead harness identity resources to support a transition to a recovery identity. © 2016 The British Psychological Society.

Political, religious and occupational identities in context: placing identity status paradigm in context.

Solomontos-Kountouri, Olga; Hurry, Jane

2008-04-01

This study critically contrasts global identity with domain-specific identities (political, religious and occupational) and considers context and gender as integral parts of identity. In a cross-sectional survey, 1038 Greek Cypriot adolescents (449 boys and 589 girls, mean age 16.8) from the three different types of secondary schools (state, state technical and private) and from different SES completed part of the Extended Objective Measure of Ego Identity Status-2 (EOMEIS-2). The macro-context of Greek Cypriot society is used to understand the role of context in adolescents' identities. Results showed that Greek Cypriot young people were not in the same statuses across their global, political, religious and occupational identities. This heterogeneity in the status of global identity and of each identity domain is partially explained by differences in gender, type of school and SES (socio-economic status). The fact that identity status is found to be reactive to context suggests that developmental stage models of identity status should place greater emphasis on context.

Changes in parental self-identity following the death of a child to cancer.

2014-01-01

This study explored parental self-identity at 6, 12, and 18 months following the death of a child to cancer. Semi-structured interviews were analyzed using qualitative methodology. Two patterns of parental self-identity emerged: identity reintegration, characterized by 6 associated themes (e.g., positive reframing, focusing on surviving children); and identity disintegration, characterized by 7 associated themes (e.g., negative perceptions of social support, self-destructive thoughts and behaviors). Patterns were stable from 6 to 12 months, but a shift towards identity disintegration was observed at 18 months. These findings suggest a need to support bereaved parents' well-being beyond the first year post-death.

The major problem in producing artificial livers is that primary hepatocytes cannot be cultured for many days. Recently, 3-dimensional (3D) printing technology draws attention and this technology regarded as a useful tool for current cell biology. By using the 3D bio-printing, these problems can be resolved. To generate 3D bio-printed structures (25 mm × 25 mm), cells-alginate constructs were fabricated by 3D bio-printing system. Mouse primary hepatocytes were isolated from the livers of 6-8 weeks old mice by a 2-step collagenase method. Samples of 4 × 10 7 hepatocytes with 80%-90% viability were printed with 3% alginate solution, and cultured with well-defined culture medium for primary hepatocytes. To confirm functional ability of hepatocytes cultured on 3D alginate scaffold, we conducted quantitative real-time polymerase chain reaction and immunofluorescence with hepatic marker genes. Isolated primary hepatocytes were printed with alginate. The 3D printed hepatocytes remained alive for 14 days. Gene expression levels of Albumin , HNF-4α and Foxa3 were gradually increased in the 3D structures. Immunofluorescence analysis showed that the primary hepatocytes produced hepatic-specific proteins over the same period of time. Our research indicates that 3D bio-printing technique can be used for long-term culture of primary hepatocytes. It can therefore be used for drug screening and as a potential method of producing artificial livers.

SPF/DB primary structure for supersonic aircraft (T-38 horizontal stabilizer)

1981-01-01

The structural integrity and potential cost savings of superplastic forming/diffusion bonding (SPF/DB) titanium structure for future Supersonic Cruise Research (SCR) and military aircraft primary structure applications was demonstrated. Using the horizontal stabilizer of the T-38 aircraft as a baseline, the structure was redesigned to the existing criteria and loads, using SPF/DB titanium technology. The general concept of using a full-depth sandwich structure which is attached to a steel spindle, was retained. Trade studies demonstrated that the optimum design should employ double-truss, sinewave core in the deepest section of the surface, making a transition to single-truss core in the thinner areas at the leading and trailing edges and at the tip. At the extreme thin edges of the surface, the single-truss core was changed to dot core to provide for gas passages during the SPF/DB process. The selected SPF/DB horizontal stabilizer design consisted of a one-piece SPF/DB sinewave truss core panel, a trunnion fitting, and reinforcing straps. The fitting and the straps were mechanically fastened to the SPF/DB panel.

Social and psychological creativity in gay male midlife identity management.

Hajek, Christopher

2016-06-01

This study utilizes a qualitative thematic analysis methodology and a social identity theory framework to explore ways in which early midlife gay men report enhancing their social identities through social and psychological creativity. Face-to-face, semi-structured interviews were conducted with forty early midlife gay men (aged 40-53) in four US cities. Men discussed the collective and individual essences of their age and gay identities, including attitudes, beliefs, and behaviours that they embraced to self-enhance at midlife. These discussions emphasized differences from the younger gay outgroup, often in the context of intergenerational interaction. Identified were three strategies (and seven substrategies) that summarized the ways that interviewees constructed their identities in the interest of self-enhancement, specifically in the context of intergenerational comparisons with younger gay men. These strategies may be considered as extensions to social creativity strategies presented in Tajfel and Turner's (Psychology of intergroup relations.

Shades of American Identity: Implicit Relations between Ethnic and National Identities

PubMed Central

Devos, Thierry; Mohamed, Hafsa

2015-01-01

The issue of ethnic diversity and national identity in an immigrant nation such as the USA is a recurrent topic of debate. We review and integrate research examining the extent to which the American identity is implicitly granted or denied to members of different ethnic groups. Consistently, European Americans are implicitly conceived of as being more American than African, Asian, Latino, and even Native Americans. This implicit American = White effect emerges when explicit knowledge or perceptions point in the opposite direction. The propensity to deny the American identity to members of ethnic minorities is particularly pronounced when targets (individuals or groups) are construed through the lenses of ethnic identities. Implicit ethnic–national associations fluctuate as a function of perceivers’ ethnic identity and political orientation, but also contextual or situational factors. The tendency to equate being American with being White accounts for the strength of national identification (among European Americans) and behavioral responses including hiring recommendations and voting intentions. The robust propensity to deny the American identity to ethnic minority groups reflects an exclusionary national identity. PMID:27011765

Identity configurations: a new perspective on identity formation in contemporary society.

PubMed

Schachter, Elli P

2004-02-01

This paper deals with the theoretical construct of "identity configuration." It portrays the different possible ways in which individuals configure the relationship among potentially conflicting identifications in the process of identity formation. In order to explicate these configurations, I analyzed narratives of identity development retold by individuals describing personal identity conflicts that arise within a larger context of sociocultural conflict. Thirty Jewish modern orthodox young adults were interviewed regarding a potentially conflictual identity issue (i.e. their religious and sexual development). Their deliberations, as described in the interviews, were examined, and four different configurations were identified: a configuration based on choice and suppression; an assimilative and synthesizing configuration; a confederacy of identifications; and a configuration based on the thrill of dissonance. The different configurations are illustrated through exemplars, and the possible implications of the concept of "configuration" for identity theory are discussed.

Primary structure of inorganic polyphosphate/ATP-NAD kinase from Micrococcus flavus, and occurrence of substrate inorganic polyphosphate for the enzyme.

PubMed

Kawai, Shigeyuki; Mori, Shigetarou; Murata, Kousaku

2003-08-01

The gene encoding an inorganic polyphosphate/ATP-NAD kinase was cloned from Micrococcus flavus, and its primary structure was analyzed. Alignment of the primary structure with those of other characterized NAD kinases revealed candidate amino acid residues, mainly charged ones, that would be related to inorganic polyphosphate use. The alignment also showed that the primary structure found carried a protruding C-terminal polypeptide. Although the C-terminal polypeptide was demonstrated to be dispensable for the kinase activities, and was proposed to be removed in M. flavus, the entire primary structure including the C-terminal polypeptide was homologous with that of the ATP synthase beta chain. The inorganic polyphosphate used by the inorganic polyphosphate/ATP-NAD kinase as a phosphoryl donor was isolated from cells of M. flavus, suggesting that the ability of the enzyme to use inorganic polyphosphate is of physiological significance and is not an evolutionary trait alone.

To assess the correlations between retinal nerve fiber layer (RNFL) thickness measured with scanning laser polarimetry and visual field (VF) sensitivity in primary open-angle glaucoma (POAG) and primary angle-closure glaucoma (PACG). Prospective, comparative, observational cases series. Fifty patients with POAG and 56 patients with PACG were examined using scanning laser polarimetry with variable corneal compensation (GDx VCC; Laser Diagnostic Technologies, Inc.) and Humphrey VF analyzer (Carl Zeiss Meditec, Inc.) between August 2005 and July 2006 at Taipei Veterans General Hospital. Correlations between RNFL thickness and VF sensitivity, expressed as mean sensitivity in both decibel and 1/Lambert scales, were estimated by the Spearman rank correlation coefficient (r(s)) and multivariate median regression models (pseudo R(2)). The correlations were determined globally and for 6 RNFL sectors and their corresponding VF regions. The correlation between RNFL thickness and mean sensitivity (in decibels) was weaker in the PACG group (r(s) = 0.38; P = .004; pseudo R(2) = 0.17) than in the POAG group (r(s) = 0.51; P < .001; pseudo R(2) = .31), but the difference in the magnitude of correlation was not significant (P = .42). With Bonferroni correction, the structure-function correlation was significant in the superotemporal (r(s) = 0.62), superonasal (r(s) = 0.56), inferonasal (r(s) = 0.53), and inferotemporal (r(s) = 0.50) sectors in the POAG group (all P < .001), whereas it was significant only in the superotemporal (r(s) = 0.53) and inferotemporal (r(s) = 0.48) sectors in the PACG group (both P < .001). The results were similar when mean sensitivity was expressed as 1/Lambert scale. Both POAG and PACG eyes had moderate structure-function correlations using scanning laser polarimetry. Compared with eyes with POAG, fewer RNFL sectors have significant structure-function correlations in eyes with PACG. Copyright 2010 Elsevier Inc. All rights reserved.

Purpose To assess the correlations between retinal nerve fiber layer (RNFL) thickness measured with scanning laser polarimetry (SLP) and visual field (VF) sensitivity in primary open angle glaucoma (POAG) and primary angle-closure glaucoma (PACG). Design Prospective, comparative, observational cases series Methods Fifty patients with POAG and 56 with PACG were examined using SLP with variable corneal compensation (GDx VCC) and Humphrey VF analyzer between August 2005 and July 2006 at Taipei Veterans General Hospital. Correlations between RNFL thickness and VF sensitivity, expressed as mean sensitivity (MS) in both decibel (dB) and 1/Lambert (L) scales, were estimated by Spearman's rank correlation coefficient (rs) and multivariate median regression models (pseudo R2). The correlations were determined globally and for six RNFL sectors and their corresponding VF regions. Results The correlation between RNFL thickness and MS (in dB) was weaker in the PACG group (rs = 0.38, P = 0.004, pseudo R2 = 0.17) than in the POAG group (rs = 0.51, P <0.001, pseudo R2 = 0.31), but the difference in the magnitude of correlation was not significant (P = 0.42).With Bonferroni correction, the structure-function correlation was significant in the superotemporal (rs = 0.62), superonasal (rs = 0.56), inferonasal (rs = 0.53), and inferotemporal (rs = 0.50) sectors in the POAG group (all P <0.001), while it was significant only in the superotemporal (rs = 0.53) and inferotemporal (rs = 0.48) sectors in the PACG group (both P <0.001). The results were similar when MS was expressed as 1/L scale. Conclusions Both POAG and PACG eyes had moderate structure-function correlations using SLP. Compared to eyes with POAG, fewer RNFL sectors have significant structure-function correlations in eyes with PACG. PMID:20202618

Circular RNAs (circRNAs) are single-stranded RNAs that are joined head to tail with largely unknown functions. Here we show that transfection of purified in vitro generated circRNA into mammalian cells led to potent induction of innate immunity genes and confers protection against viral infection. The nucleic acid sensor RIG-I is necessary to sense foreign circRNA, and RIG-I and foreign circRNA co-aggregate in cytoplasmic foci. CircRNA activation of innate immunity is independent of a 5' triphosphate, double-stranded RNA structure, or the primary sequence of the foreign circRNA. Instead, self-nonself discrimination depends on the intron that programs the circRNA. Use of a human intron to express a foreign circRNA sequence abrogates immune activation, and mature human circRNA is associated with diverse RNA binding proteins reflecting its endogenous splicing and biogenesis. These results reveal innate immune sensing of circRNA and highlight introns-the predominant output of mammalian transcription-as arbiters of self-nonself identity. Copyright © 2017 Elsevier Inc.

The importance of predators in influencing community structure is a well-studied area of ecology. However, few studies test ecological hypotheses of predation in multi-predator microbial communities. The phytotelmic community found within the water-filled leaves of the pitcher plant, Sarracenia purpurea, exhibits a simple trophic structure that includes multiple protozoan predators and microbial prey. Using this system, we sought to determine whether different predators target distinct microorganisms, how interactions among protozoans affect resource (microorganism) use, and how predator diversity affects prey community diversity. In particular, we endeavored to determine if protozoa followed known ecological patterns such as keystone predation or generalist predation. For these experiments, replicate inquiline microbial communities were maintained for seven days with five protozoan species. Microbial community structure was determined by 16S rRNA gene amplicon sequencing (iTag) and analysis. Compared to the control (no protozoa), two ciliates followed patterns of keystone predation by increasing microbial evenness. In pairwise competition treatments with a generalist flagellate, prey communities resembled the microbial communities of the respective keystone predator in monoculture. The relative abundance of the most common bacterial Operational Taxonomic Unit (OTU) in our system decreased compared to the control in the presence of these ciliates. This OTU was 98% similar to a known chitin degrader and nitrate reducer, important functions for the microbial community and the plant host. Collectively, the data demonstrated that predator identity had a greater effect on prey diversity and composition than overall predator diversity. © 2018 by the Ecological Society of America.

Non-linear analysis methods were adapted and incorporated in a finite element based DIAL code. These methods are necessary to evaluate the global response of a stiffened structure under combined in-plane and out-of-plane loading. These methods include the Arc Length method and target point analysis procedure. A new interface material model was implemented that can model elastic-plastic behavior of the bond adhesive. Direct application of this method is in skin/stiffener interface failure assessment. Addition of the AML (angle minus longitudinal or load) failure procedure and Hasin's failure criteria provides added capability in the failure predictions. Interactive Stiffened Panel Analysis modules were developed as interactive pre-and post-processors. Each module provides the means of performing self-initiated finite elements based analysis of primary structures such as a flat or curved stiffened panel; a corrugated flat sandwich panel; and a curved geodesic fuselage panel. This module brings finite element analysis into the design of composite structures without the requirement for the user to know much about the techniques and procedures needed to actually perform a finite element analysis from scratch. An interactive finite element code was developed to predict bolted joint strength considering material and geometrical non-linearity. The developed method conducts an ultimate strength failure analysis using a set of material degradation models.

Proteins that share common ancestry may differ in structure and function because of divergent evolution of their amino acid sequences. For a typical diverse protein superfamily, the properties of a few scattered members are known from experiment. A satisfying picture of functional and structural evolution in relation to sequence changes, however, may require characterization of a larger, well chosen subset. Here, we employ a “stepping-stone” method, based on transitive homology, to target sequences intermediate between two related proteins with known divergent properties. We apply the approach to the question of how new protein folds can evolve from preexisting folds and, in particular, to an evolutionary change in secondary structure and oligomeric state in the Cro family of bacteriophage transcription factors, initially identified by sequence-structure comparison of distant homologs from phages P22 and λ. We report crystal structures of two Cro proteins, Xfaso 1 and Pfl 6, with sequences intermediate between those of P22 and λ. The domains show 40% sequence identity but differ by switching of α-helix to β-sheet in a C-terminal region spanning ≈25 residues. Sedimentation analysis also suggests a correlation between helix-to-sheet conversion and strengthened dimerization. PMID:18227506

Racial identity invalidation with multiracial individuals: An instrument development study.

PubMed

Franco, Marisa G; O'Brien, Karen M

2018-01-01

Racial identity invalidation, others' denial of an individual's racial identity, is a salient racial stressor with harmful effects on the mental health and well-being of Multiracial individuals. The purpose of this study was to create a psychometrically sound measure to assess racial identity invalidation for use with Multiracial individuals (N = 497). The present sample was mostly female (75%) with a mean age of 26.52 years (SD = 9.60). The most common racial backgrounds represented were Asian/White (33.4%) and Black/White (23.7%). Participants completed several online measures via Qualtrics. Exploratory factor analyses revealed 3 racial identity invalidation factors: behavior invalidation, phenotype invalidation, and identity incongruent discrimination. A confirmatory factor analysis provided support for the initial factor structure. Alternative model testing indicated that the bifactor model was superior to the 3-factor model. Thus, a total score and/or 3 subscale scores can be used when administering this instrument. Support was found for the reliability and validity of the total scale and subscales. In line with the minority stress theory, challenges with racial identity mediated relationships between racial identity invalidation and mental health and well-being outcomes. The findings highlight the different dimensions of racial identity invalidation and indicate their negative associations with connectedness and psychological well-being.

Exploring the link between environmental identity, behaviors and decision making

NASA Astrophysics Data System (ADS)

Freed, Allison

This study was conducted with undergraduate students at a large university to investigate the association between environmental identity, pro-environmental behaviors and environmental decision-making. This study explored how environmental identity as defined by Clayton (2003) influenced the type of pro-environmental behaviors individuals choose to participate in. Environmental decision-making based on Kahneman's (2003, 2011) System 1 and System 2 framework was also assessed in association with environmental identity. A survey including the Environmental Identity Survey (Clayton, 2003), the Environmentally Responsible Behaviors Index (Smith-Sebasto & D'Acosta, 1995), and a Decision Making Questionnaire were administered. After administering the surveys, eight participants were chosen for a 60-minute interview. The quantitative results of the study showed there was a significant relationship between environmental identity and participating in environmental behaviors more often. There was also a significant relation between environmental identity and making the decision to recycle in a fast and automatic way. The interview results showed that participants with both a strong and a weak environmental identity recycled often and thought it was a fast decision. The results of this study show that certain components of environmental identity are important, but other factors like the physical environment and social norms influence the thinking that goes into recycling more than environmental identity alone. This study provides evidence of the importance of social norms and environmental structures in fostering pro-environmental behaviors and influencing the type of thinking that goes into making environmental decisions. Keywords: environmental identity, environmental behaviors, System 1, System 2, recycling.

A scorpion venom neurotoxin paralytic to insects that affects sodium current inactivation: Purification, primary structure, and mode of action

Eitan, M.; Fowler, E.; Herrmann, R.

1990-06-26

A new toxin, Lqh alpha IT, which caused a unique mode of paralysis of blowfly larvae, was purified from the venom of the scorpion Leiurus quinquestriatus hebraeus, and its structural and pharmacological properties were compared to those of three other groups of neurotoxins found in Buthinae scorpion venoms. Like the excitatory and depressant insect-selective neurotoxins, Lqh alpha IT was highly toxic to insects, but it differed from these toxins in two important characteristics: (a) Lqh alpha IT lacked strict selectivity for insects; it was highly toxic to crustaceans and had a measurable but low toxicity to mice. (b) It didmore » not displace an excitatory insect toxin, 125I-AaIT, from its binding sites in the insect neuronal membrane; this indicates that the binding sites for Lqh alpha IT are different from those shared by the excitatory and depressant toxins. However, in its primary structure and its effect on excitable tissues, Lqh alpha IT strongly resembled the well-characterized alpha scorpion toxins, which affect mammals. The amino acid sequence was identical with alpha toxin sequences in 55%-75% of positions. This degree of similarity is comparable to that seen among the alpha toxins themselves. Voltage- and current-clamp studies showed that Lqh alpha IT caused an extreme prolongation of the action potential in both cockroach giant axon and rat skeletal muscle preparations as a result of the slowing and incomplete inactivation of the sodium currents. These observations indicate that Lqh alpha IT is an alpha toxin which acts on insect sodium channels.« less

Contextual influences on ethnic identity formation: a case study of second-generation Korean Americans Baby Boomers in midlife.

PubMed

Park, Linda S

2015-03-01

This paper details a study on ethnic identity in midlife, illuminating identity formation as a complex life course phenomenon. The study addresses the importance of ethnic identity in understanding the experiences of racial and ethnic Baby Boomers as both recipients of care and as caregivers to their aging parents (first generation immigrants). Using a case study of second-generation Korean American Baby Boomers, the primary aims of this study are: (a) to explore how the relationship between age and race/ethnicity influences identity formation, and (b) how contexts influence ethnic identity formation. Findings reveal that cumulative experiences over earlier developmental years resulted in resolutions to appreciate their ethnic identity at midlife. Increasing racial and ethnic diversity in the U.S., combined with the large number of aging Baby Boomers, necessitate recognition of the cultural and racial differences within the Baby Boomer generation.

When I know who "we" are, I can be "me": the primary role of cultural identity clarity for psychological well-being.

PubMed

Taylor, Donald M; Usborne, Esther

2010-02-01

Collective trauma, be it through colonization (e.g., Aboriginal Peoples), slavery (e.g., African Americans) or war, has a dramatic impact on the psychological well-being of each and every individual member of the collective. Thus, interventions are often conceptualized and delivered at the individual level with a view to minimizing the psychological disequilibrium of each individual. In contrast, we propose a theory of self that emphasizes the primacy of cultural identity for psychological well-being. We present a series of studies that illustrate the importance of cultural identity clarity for personal identity and for psychological well-being. Our theoretical model proposes that interventions aimed at clarifying cultural identity may play a constructive role in the promotion of the well-being of group members exposed to collective trauma.

Silos and Social Identity: The Social Identity Approach as a Framework for Understanding and Overcoming Divisions in Health Care

PubMed Central

Kreindler, Sara A; Dowd, Damien A; Dana Star, Noah; Gottschalk, Tania

2012-01-01

Context One of health care's foremost challenges is the achievement of integration and collaboration among the groups providing care. Yet this fundamentally group-related issue is typically discussed in terms of interpersonal relations or operational issues, not group processes. Methods We conducted a systematic search for literature offering a group-based analysis and examined it through the lens of the social identity approach (SIA). Founded in the insight that group memberships form an important part of the self-concept, the SIA encompasses five dimensions: social identity, social structure, identity content, strength of identification, and context. Findings Our search yielded 348 reports, 114 of which cited social identity. However, SIA-citing reports varied in both compatibility with the SIA's metatheoretical paradigm and applied relevance to health care; conversely, some non-SIA-citers offered SIA-congruent analyses. We analyzed the various combinations and interpretations of the five SIA dimensions, identifying ten major conceptual currents. Examining these in the light of the SIA yielded a cohesive, multifaceted picture of (inter)group relations in health care. Conclusions The SIA offers a coherent framework for integrating a diverse, far-flung literature on health care groups. Further research should take advantage of the full depth and complexity of the approach, remain sensitive to the unique features of the health care context, and devote particular attention to identity mobilization and context change as key drivers of system transformation. Our article concludes with a set of “guiding questions” to help health care leaders recognize the group dimension of organizational problems, identify mechanisms for change, and move forward by working with and through social identities, not against them.

The role of self-identity in predicting fruit and vegetable intake.

PubMed

Carfora, V; Caso, D; Conner, M

2016-11-01

This research investigated whether the Theory of Planned Behavior (TPB) with the addition of self-identity could predict fruit and vegetable intake when controlling for past behavior. Previous research had demonstrated the efficacy of TPB to predict intention and behavior in relation to food choice and the additional power of self-identity, but had failed assess the effects of self-identity while controlling for past behavior. At baseline (N = 210) TPB components and past behavior in relation to fruit and vegetable consumption plus self-identity as a healthy eater were measured by questionnaire in a sample of university students. At time 1, 4 weeks later, self-reported fruit and vegetable consumption was measured. Structural Equation Modelling (SEM) indicated attitude, PBC and self-identity to be significant predictors of intention (subjective norm and past behavior were not significant). Intention, self-identity and past behavior were direct predictors of behavior. The current findings support the independent effect of self-identity as a healthy eater on both intentions and future behaviour when controlling for TPB variables and also past behavior. The discussion considers the importance of self-identity in changing intentions and behavior for behaviors such as fruit and vegetable consumption. Copyright © 2015 Elsevier Ltd.

Korsakoff syndrome presents with memory dysfunction with retrograde amnesia, anterograde amnesia, limited insight into dysfunction, and confabulation. The most common etiology of Korsakoff syndrome is thiamine deficiency secondary to alcoholism. There are limited case reports of structural lesions causing Korsakoff syndrome. A 46-year-old male with a long history of alcoholism presented with a history of confusion, amnesia, and confabulation with no localizing features on neurological examination. The patient showed no clinical change with intravenous thiamine. Computed tomography of the brain revealed a heterogenous, enhancing mass lesion centered within the third ventricle, with other lesions found throughout cortical and subcortical regions. The patient was given dexamethasone i.v. without noticeable clinical improvement but with marked radiological improvement with mass reduction. Stereotactic biopsy revealed a diagnosis of primary central nervous system (CNS) lymphoma. Most patients presenting with Korsakoff syndrome have thiamine deficiency; however, mass lesions can produce an identical clinical picture. This is the first case report of a patient with primary CNS lymphoma presenting as Korsakoff syndrome.

Spatial separation and entanglement of identical particles

Cunden, Fabio Deelan; di Martino, Sara; Facchi, Paolo; Florio, Giuseppe

2014-04-01

We reconsider the effect of indistinguishability on the reduced density operator of the internal degrees of freedom (tracing out the spatial degrees of freedom) for a quantum system composed of identical particles located in different spatial regions. We explicitly show that if the spin measurements are performed in disjoint spatial regions then there are no constraints on the structure of the reduced state of the system. This implies that the statistics of identical particles has no role from the point of view of separability and entanglement when the measurements are spatially separated. We extend the treatment to the case of n particles and show the connection with some recent criteria for separability based on subalgebras of observables.

This qualitative study was conducted to explore the images of personal identity from the perspective of women with sexual addiction. The data required for the study were collected through 31 in-depth interviews. Sensing a threat to personal identity, dissatisfaction with gender identity, dissociation with the continuum of identity, and identity reconstruction in response to threat were four of the experiences that were common among women with sexual addiction. Painful emotional experiences appear to have created a sense of gender and sexual conflict or weakness in these women and thus threatened their personal identity and led to their sexual addiction.

Student Identity Considerations and Implications Associated with Socioscientific Issues Instruction

NASA Astrophysics Data System (ADS)

Ruzek, Mitchel James

The purpose of this investigation was to explore how aspects of identity, perceived levels of controversy, and the strength of a student's attachment to their controversial identity relate to conceptual understanding and knowledge acquisition during socioscientific issues (SSI) based instruction in a biology classroom. The knowledge gained from this study will have the capacity to enhance our understanding of the role that attachment to identity plays during SSI negotiation. Additionally, insight was gained into the role played by aspects of identity in conceptual understanding of scientifically controversial topics during SSI based instruction. This study contributed to the existing knowledge base in science education by illuminating processes involved in socioscientific issue navigation among students of differing perceptions of controversy as well as students who held aspects of controversial identity that may or may not interact with the specific issues chosen. Students demonstrated evidence of variations of reasoning, justification, perception of controversy, and aspects of knowledge gain as they negotiated the issues of marijuana safety and fast food legality. Additionally, evidence was provided that showed general knowledge gain throughout the group during socioscientific issues instruction. It has been said that one of the appeals of the SSI instructional model is that is serves not only as a context for the delivery of content, but acts as a catalyst for various forms of epistemological beliefs and research into the development of conceptual and psychological knowledge structures (Zeidler, 2013). This investigation supports the deeper understanding of the contribution of controversy perception to epistemology as well as conceptual and psychological knowledge structures during SSI navigation.

2018-01-01

In this paper, we first analytically calculate the eigenvalues of the transition matrix of a structure with very complex architecture and their multiplicities. We call this structure polymer network. Based on the eigenvalues obtained in the iterative manner, we then calculate the eigentime identity. We highlight two scaling behaviors (logarithmic and linear) for this quantity, strongly depending on the value of the weight factor. Finally, by making use of the obtained eigenvalues, we determine the weighted counting of spanning trees.

Knowledge of identity and reputation: Do people have knowledge of others' perceptions?

PubMed

Solomon, Brittany C; Vazire, Simine

2016-09-01

It may be important to know when our impressions of someone differ from how that person sees him/herself and how others see that same person. We investigated whether people are aware of how their friends see themselves (knowledge of identity) and are seen by others (knowledge of reputation). Previous research indicates that, for physical attractiveness, romantic partners do have such knowledge of others' perceptions, but it is unknown whether people in platonic relationships also detect such discrepancies between their own perceptions and others'. We examined this phenomenon for a new set of characteristics: the Big Five personality traits. Our primary research questions pertained to identity accuracy and reputation accuracy (i.e., knowledge of a target's self-views and how others view the target, respectively) and identity insight and reputation insight (i.e., identity accuracy and reputation accuracy that cannot be accounted for by a potential artifact: perceivers assuming that others share their own views of targets). However, after a series of preliminary tests, we did not examine reputation insight, as several necessary conditions were not met, indicating that any effects would likely be spurious. We did find that perceivers can accurately infer a target's identity and reputation on global personality traits (identity and reputation accuracy), and that perceivers can sometimes accurately distinguish between their own perceptions of targets and targets' self-views, but not others' views of targets (i.e., identity, but not reputation, insight). Finally, we explored boundary conditions for knowledge of others' perceptions and whether knowledge of identity is correlated with knowledge of reputation.

Science literacy and academic identity formulation

NASA Astrophysics Data System (ADS)

Reveles, John M.; Cordova, Ralph; Kelly, Gregory J.

2004-12-01

The purpose of this article is to report findings from an ethnographic study that focused on the co-development of science literacy and academic identity formulation within a third-grade classroom. Our theoretical framework draws from sociocultural theory and studies of scientific literacy. Through analysis of classroom discourse, we identified opportunities afforded students to learn specific scientific knowledge and practices during a series of science investigations. The results of this study suggest that the collective practice of the scientific conversations and activities that took place within this classroom enabled students to engage in the construction of communal science knowledge through multiple textual forms. By examining the ways in which students contributed to the construction of scientific understanding, and then by examining their performances within and across events, we present evidence of the co-development of students' academic identities and scientific literacy. Students' communication and participation in science during the investigations enabled them to learn the structure of the discipline by identifying and engaging in scientific activities. The intersection of academic identities with the development of scientific literacy provides a basis for considering specific ways to achieve scientific literacy for all students.

In research oriented universities, research and teaching are often viewed as separate. Aydeniz and Hodge present one professor's struggles to synthesize an identity from three different spaces, each with competing values and core beliefs. As Mr. G's story unfolds, and he reflects upon his negotiation between teaching and research responsibilities, we seek to expand the discussion by presenting a caution to identity researchers. The caution pertains to construction of understanding on how identities are created, and the role that individual stories take in how identities are created and enacted. In this forum contribution, we present several questions in the hopes of furthering the discussion on identity research, and our understanding of the conceptualization of institutional boundaries and objectivity, as well as questions on participant involvement in the process of research.

Linking academic social environments, ego-identity formation, ego virtues, and academic success.

PubMed

Good, Marie; Adams, Gerald R

2008-01-01

This study used Structural Equation Modeling to test an Eriksonian conceptual model linking academic social environments (relationships with faculty and fellow students), ego-identity formation, ego virtues, and academic success. Participants included 765 first-year students at a university in southern Ontario, Canada. Results indicated that supportive relationships with faculty was directly related to higher average grades and perceived academic ability, whereas positive relationships with fellow students was indirectly related to academic success through ego virtues. Positive ego-identity formation (identity achievement) was also indirectly related to academic success through ego virtues.

Social Identity in People with Multiple Sclerosis: An Examination of Family Identity and Mood.

Mood disorders are highly prevalent in people with multiple sclerosis (MS). MS causes changes to a person's sense of self. The Social Identity Model of Identity Change posits that group membership can have a positive effect on mood during identity change. The family is a social group implicated in adjustment to MS. The objectives of this study were to investigate whether family identity can predict mood in people with MS and to test whether this prediction was mediated by social support and connectedness to others. This cross-sectional survey of 195 participants comprised measures of family identity, family social support, connectedness to others, and mood. Family identity predicted mood both directly and indirectly through parallel mediators of family social support and connectedness to others. Family identity predicted mood as posited by the Social Identity Model of Identity Change. Involving the family in adjustment to MS could reduce low mood.

Identity-specific motivation: How distinct identities direct self-regulation across distinct situations.

PubMed

Browman, Alexander S; Destin, Mesmin; Molden, Daniel C

2017-12-01

Research on self-regulation has traditionally emphasized that people's thoughts and actions are guided by either (a) domain-general motivations that emerge from a cumulative history of life experiences, or (b) situation-specific motivations that emerge in immediate response to the incentives present in a particular context. However, more recent studies have illustrated the importance of understanding the interplay between such domain-general and situation-specific motivations across the types of contexts people regularly encounter. The present research, therefore, expands existing perspectives on self-regulation by investigating how people's identities -the internalized roles, relationships, and social group memberships that define who they are-systemically guide when and how different domain-general motivations are activated within specific types of situations. Using the motivational framework described by regulatory focus theory (Higgins, 1997), Studies 1 and 2 demonstrate that people indeed have distinct, identity-specific motivations that uniquely influence their current self-regulation when such identities are active. Studies 3-5 then begin to explore how identity-specific motivations are situated within people's larger self-concept. Studies 3a and 3b demonstrate that the less compatible people's specific identities, the more distinct are the motivations connected to those identities. Studies 4-5 then provide some initial, suggestive evidence that identity-specific motivations are not a separate, superordinate feature of people's identities that then alter how they pursue any subordinate, identity-relevant traits, but instead that such motivations emerge from the cumulative motivational significance of the subordinate traits to which the identities themselves become attached. Implications for understanding the role of the self-concept in self-regulation are discussed. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

Social identities prescribe behaviors for people. We identify the marginal behavioral effect of these norms on discount rates and risk aversion by measuring how laboratory subjects’ choices change when an aspect of social identity is made salient. When we make ethnic identity salient to Asian-American subjects, they make more patient choices. When we make racial identity salient to black subjects, non-immigrant blacks (but not immigrant blacks) make more patient choices. Making gender identity salient has no effect on intertemporal or risk choices. PMID:20871741

Exploring positioning as an analytical tool for understanding becoming mathematics teachers' identities

Skog, Kicki; Andersson, Annica

2015-03-01

The aim of this article is to explore how a sociopolitical analysis can contribute to a deeper understanding of critical aspects for becoming primary mathematics teachers' identities during teacher education. The question we ask is the following: How may power relations in university settings affect becoming mathematics teachers' subject positioning? We elaborate on the elusive and interrelated concepts of identity, positioning and power, seen as dynamic and changeable. As these concepts represent three interconnected parts of research analysis in an on-going larger project data from different sources will be used in this illustration. In this paper, we clarify the theoretical stance, ground the concepts historically and strive to connect them to research analysis. In this way, we show that power relations and subject positioning in social settings are critical aspects and need to be taken seriously into account if we aim at understanding becoming teachers' identities.

Memory transfer for emotionally valenced words between identities in dissociative identity disorder.

2007-04-01

The present study aimed to determine interidentity retrieval of emotionally valenced words in dissociative identity disorder (DID). Twenty-two DID patients participated together with 25 normal controls and 25 controls instructed to simulate DID. Two wordlists A and B were constructed including neutral, positive and negative material. List A was shown to one identity, while list B was shown to another identity claiming total amnesia for the words learned by the first identity. The identity claiming amnesia was tested for intrusions from list A words into the recall of words from list B and recognition of the words learned by both identities. Test results indicated no evidence of total interidentity amnesia for emotionally valenced material in DID. It is argued that dissociative amnesia in DID may more adequately be described as a disturbance in meta-memory functioning instead of an actual retrieval inability.

Humans inhabit environments that are both social and physical, and in this article we investigate if and how social identity processes shape the experience and negotiation of physically demanding environmental conditions. Specifically, we consider how severe cold can be interpreted and experienced in relation to group members' social identity. Our data comprise ethnographic observation and semi-structured interviews with pilgrims attending a month-long winter Hindu religious festival that is characterized by near-freezing conditions. The analysis explores (1) how pilgrims appraised the cold and how these appraisals were shaped by their identity as pilgrims; (2) how shared identity with other pilgrims led to forms of mutual support that made it easier to cope with the cold. Our findings therefore extend theorizing on social identity processes to highlight their relevance to physical as well as social conditions. © 2013 The British Psychological Society.

Identity modulates short-term memory for facial emotion.

2009-12-01

For some time, the relationship between processing of facial expression and facial identity has been in dispute. Using realistic synthetic faces, we reexamined this relationship for both perception and short-term memory. In Experiment 1, subjects tried to identify whether the emotional expression on a probe stimulus face matched the emotional expression on either of two remembered faces that they had just seen. The results showed that identity strongly influenced recognition short-term memory for emotional expression. In Experiment 2, subjects' similarity/dissimilarity judgments were transformed by multidimensional scaling (MDS) into a 2-D description of the faces' perceptual representations. Distances among stimuli in the MDS representation, which showed a strong linkage of emotional expression and facial identity, were good predictors of correct and false recognitions obtained previously in Experiment 1. The convergence of the results from Experiments 1 and 2 suggests that the overall structure and configuration of faces' perceptual representations may parallel their representation in short-term memory and that facial identity modulates the representation of facial emotion, both in perception and in memory.

Farming practices affect the soil microbial community, which in turn impacts crop growth and crop-weed interactions. This study assessed the modification of soil bacterial community structure by organic or conventional cropping systems, weed species identity [Amaranthus retroflexus L. (redroot pigweed) or Avena fatua L. (wild oat)], and living or sterilized inoculum. Soil from eight paired USDA-certified organic and conventional farms in north-central Montana was used as living or autoclave-sterilized inoculant into steam-pasteurized potting soil, planted with Am. retroflexus or Av. fatua and grown for two consecutive 8-week periods to condition soil nutrients and biota. Subsequently, the V3-V4 regions of the microbial 16S rRNA gene were sequenced by Illumina MiSeq. Treatments clustered significantly, with living or sterilized inoculum being the strongest delineating factor, followed by organic or conventional cropping system, then individual farm. Living inoculum-treated soil had greater species richness and was more diverse than sterile inoculum-treated soil (observed OTUs, Chao, inverse Simpson, Shannon, P < 0.001) and had more discriminant taxa delineating groups (linear discriminant analysis). Living inoculum soil contained more Chloroflexi and Acidobacteria, while the sterile inoculum soil had more Bacteroidetes, Firmicutes, Gemmatimonadetes, and Verrucomicrobia. Organically farmed inoculum-treated soil had greater species richness, more diversity (observed OTUs, Chao, Shannon, P < 0.05), and more discriminant taxa than conventionally farmed inoculum-treated soil. Cyanobacteria were higher in pots growing Am. retroflexus, regardless of inoculum type, for three of the four organic farms. Results highlight the potential of cropping systems and species identity to modify soil bacterial communities, subsequently modifying plant growth and crop-weed competition.

The American Psychological Association defines gender identity as, "A person's deeply-felt, inherent sense of being a boy, a man, or a male; a girl, a woman, or a female; or an alternative gender (e.g., genderqueer, gender nonconforming, gender neutral) that may or may not correspond to a person's sex assigned at birth or to a person's primary or secondary sex characteristics" (American Psychological Association, Am Psychol 70(9):832-864, 2015). Here we review the evidence that gender identity and related socially defined gender constructs are influenced in part by innate factors including genes. Based on the data reviewed, we hypothesize that gender identity is a multifactorial complex trait with a heritable polygenic component. We argue that increasing the awareness of the biological diversity underlying gender identity development is relevant to all domains of social, medical, and neuroscience research and foundational for reducing health disparities and promoting human-rights protections for gender minorities.

Primary structure and cellular localization of chicken brain myosin-V (p190), an unconventional myosin with calmodulin light chains

PubMed Central

1992-01-01

Recent biochemical studies of p190, a calmodulin (CM)-binding protein purified from vertebrate brain, have demonstrated that this protein, purified as a complex with bound CM, shares a number of properties with myosins (Espindola, F. S., E. M. Espreafico, M. V. Coelho, A. R. Martins, F. R. C. Costa, M. S. Mooseker, and R. E. Larson. 1992. J. Cell Biol. 118:359-368). To determine whether or not p190 was a member of the myosin family of proteins, a set of overlapping cDNAs encoding the full-length protein sequence of chicken brain p190 was isolated and sequenced. Verification that the deduced primary structure was that of p190 was demonstrated through microsequence analysis of a cyanogen bromide peptide generated from chick brain p190. The deduced primary structure of chicken brain p190 revealed that this 1,830-amino acid (aa) 212,509-D) protein is a member of a novel structural class of unconventional myosins that includes the gene products encoded by the dilute locus of mouse and the MYO2 gene of Saccharomyces cerevisiae. We have named the p190-CM complex "myosin-V" based on the results of a detailed sequence comparison of the head domains of 29 myosin heavy chains (hc), which has revealed that this myosin, based on head structure, is the fifth of six distinct structural classes of myosin to be described thus far. Like the presumed products of the mouse dilute and yeast MYO2 genes, the head domain of chicken myosin-V hc (aa 1-764) is linked to a "neck" domain (aa 765-909) consisting of six tandem repeats of an approximately 23-aa "IQ-motif." All known myosins contain at least one such motif at their head-tail junctions; these IQ-motifs may function as calmodulin or light chain binding sites. The tail domain of chicken myosin-V consists of an initial 511 aa predicted to form several segments of coiled-coil alpha helix followed by a terminal 410-aa globular domain (aa, 1,421-1,830). Interestingly, a portion of the tail domain (aa, 1,094-1,830) shares 58% amino acid

LGBTQ+ Young Adults on the Street and on Campus: Identity as a Product of Social Context.

Schmitz, Rachel M; Tyler, Kimberly A

2018-01-01

Lesbian, gay, bisexual, queer, and other sexual and gender minority (LGBTQ+) young adults face unique identity-related experiences based on their immersion in distinctive social contexts. The predominant framework of performing separate analyses on samples of LGBTQ+ young people by their primary social status obfuscates more holistic understandings of the role of social context. Using 46 in-depth interviews with LGBTQ+ college students and LGBTQ+ homeless young adults, we ask: How are LGBTQ+ young adults' capacities for "doing" their gender and sexual identities shaped by their distinctive social contexts? In developing their identities, both groups of LGBTQ+ young adults navigated their social environments to seek out resources and support. Most college students described their educational contexts as conducive to helping them develop their identities, or "undo" rigid norms of gender and sexuality. Homeless young adults' social environments, meanwhile, imposed complex barriers to self-expression that reinforced more normative expectations of "doing" gender and sexual identities.

Identity development in adolescents with mental problems

PubMed Central

2013-01-01

Background In the revision of the Diagnostic and Statistical Manual (DSM-5), “Identity” is an essential diagnostic criterion for personality disorders (self-related personality functioning) in the alternative approach to the diagnosis of personality disorders in Section III of DSM-5. Integrating a broad range of established identity concepts, AIDA (Assessment of Identity Development in Adolescence) is a new questionnaire to assess pathology-related identity development in healthy and disturbed adolescents aged 12 to 18 years. Aim of the present study is to investigate differences in identity development between adolescents with different psychiatric diagnoses. Methods Participants were 86 adolescent psychiatric in- and outpatients aged 12 to 18 years. The test set includes the questionnaire AIDA and two semi-structured psychiatric interviews (SCID-II, K-DIPS). The patients were assigned to three diagnostic groups (personality disorders, internalizing disorders, externalizing disorders). Differences were analyzed by multivariate analysis of variance MANOVA. Results In line with our hypotheses, patients with personality disorders showed the highest scores in all AIDA scales with T>70. Patients with externalizing disorders showed scores in an average range compared to population norms, while patients with internalizing disorders lay in between with scores around T=60. The AIDA total score was highly significant between the groups with a remarkable effect size of f= 0.44. Conclusion Impairment of identity development differs between adolescent patients with different forms of mental disorders. The AIDA questionnaire is able to discriminate between these groups. This may help to improve assessment and treatment of adolescents with severe psychiatric problems. PMID:23899433

Community Structure of Tintinnid Ciliates of the Microzooplankton in the South West Pacific Ocean: Comparison of a High Primary Productivity with a Typical Oligotrophic Site.

Transient 'hot spots' of phytoplankton productivity occur in the generally oligotrophic Southern Pacific Ocean and we hypothesized that the population structure of tintinnid ciliates, planktonic grazers, would differ from that of a typical oligotrophic sites. Samples were collected over a 1-wk period at each of two sites between Fiji and Tahiti: one of elevated chlorophyll a concentrations and primary productivity with an abundance of N-fixing cyanobacteria Trichodesmium, and a distant oligotrophic site. Tintinnid abundance differed between the sites by a factor of 2. A single species (Favella sp.), absent from the oligotrophic site, highly dominated the 'hot spot' site. However, total species richness was identical (71 spp.) as well as short-term temporal variability (2-4 d). At both sites, species abundance distributions most closely fit a log-series or log-normal distribution and the abundance distributions of ecological types, forms of distinct lorica oral diameter, were the typical geometric. Morphological diversity was only slightly lower at the high productivity site. We found that communities of these plankton grazers in 'hot spots' of phytoplankton productivity in oligotrophic systems, although harboring different species, differ little from surrounding oligotrophic areas in community structure. © 2016 The Author(s) Journal of Eukaryotic Microbiology © 2016 International Society of Protistologists.

Identity and Professional Networking.

Raj, Medha; Fast, Nathanael J; Fisher, Oliver

2017-06-01

Despite evidence that large professional networks afford a host of financial and professional benefits, people vary in how motivated they are to build such networks. To help explain this variance, the present article moves beyond a rational self-interest account to examine the possibility that identity shapes individuals' intentions to network. Study 1 established a positive association between viewing professional networking as identity-congruent and the tendency to prioritize strengthening and expanding one's professional network. Study 2 revealed that manipulating the salience of the self affects networking intentions, but only among those high in networking identity-congruence. Study 3 further established causality by experimentally manipulating identity-congruence to increase networking intentions. Study 4 examined whether identity or self-interest is a better predictor of networking intentions, providing support for the former. These findings indicate that identity influences the networks people develop. Implications for research on the self, identity-based motivation, and professional networking are discussed.

Design and evaluation of a foam-filled hat-stiffened panel concept for aircraft primary structural applications

NASA Technical Reports Server (NTRS)

Ambur, Damodar R.

1993-01-01

Geodesically stiffened structures are very efficient in carrying combined bending, torsion, and pressure loading that is typical of primary aircraft structures. They are also very damage tolerant since there are multiple load paths available to redistribute loads compared to prismatically stiffened structures. Geodesically stiffened structures utilize continuous filament composite materials which make them amenable to automated manufacturing processes to reduce cost. The current practice for geodesically stiffened structures is to use a solid blade construction for the stiffener. This stiffener configuration is not an efficient concept and there is a need to identify other stiffener configurations that are more efficient but utilize the same manufacturing process as the solid blade. This paper describes a foam-filled stiffener cross section that is more efficient than a solid-blade stiffener in the load range corresponding to primary aircraft structures. A prismatic hat-stiffener panel design is then selected for structural evaluation in uni-axial compression with and without impact damage. Experimental results for both single stiffener specimens and multi-stiffener panel specimens are presented. Finite element analysis results are presented that predict the buckling and postbuckling response of the test specimens. Analytical results for both the element and panel specimens are compared with experimental results.

Men as victims: "victim" identities, gay identities, and masculinities.

PubMed

Dunn, Peter

2012-11-01

The impact and meanings of homophobic violence on gay men's identities are explored with a particular focus on their identities as men and as gay men. Homosexuality can pose a challenge to conventional masculinities, and for some gay men, being victimized on account of sexual orientation reawakens conflicts about their masculinity that they thought they had resolved. Being victimized can reinvoke shame that is rooted in failure or unwillingness to uphold masculine norms. For some gay men, victimization therefore has connotations of nonmasculinity that make being a victim an undesirable status, yet that status must be claimed to obtain a response from criminal justice or victim services. Men who experience homophobic abuse are helped by accepting a victim identity, but only if they can quickly move on from it by reconstructing a masculine gay (nonvictim) identity. This process can be facilitated by agencies such as the police and victim services, provided they help men exercise agency in "fighting back," that is, resisting further victimization and recovering.

Meristem identity and phyllotaxis in inflorescence development

PubMed Central

Bartlett, Madelaine E.; Thompson, Beth

2014-01-01

Inflorescence morphology is incredibly diverse. This diversity of form has been a fruitful source of inquiry for plant morphologists for more than a century. Work in the grasses (Poaceae), the tomato family (Solanaceae), and Arabidopsis thaliana (Brassicaceae) has led to a richer understanding of the molecular genetics underlying this diversity. The character of individual meristems, a combination of the number (determinacy) and nature (identity) of the products a meristem produces, is key in the development of plant form. A framework that describes inflorescence development in terms of shifting meristem identities has emerged and garnered empirical support in a number of model systems. We discuss this framework and highlight one important aspect of meristem identity that is often considered in isolation, phyllotaxis. Phyllotaxis refers to the arrangement of lateral organs around a central axis. The development and evolution of phyllotaxis in the inflorescence remains underexplored, but recent work analyzing early inflorescence development in the grasses identified an evolutionary shift in primary branch phyllotaxis in the Pooideae. We discuss the evidence for an intimate connection between meristem identity and phyllotaxis in both the inflorescence and vegetative shoot, and touch on what is known about the establishment of phyllotactic patterns in the meristem. Localized auxin maxima are instrumental in determining the position of lateral primordia. Upstream factors that regulate the position of these maxima remain unclear, and how phyllotactic patterns change over the course of a plant's lifetime and evolutionary time, is largely unknown. A more complete understanding of the molecular underpinnings of phyllotaxis and architectural diversity in inflorescences will require capitalizing on the extensive resources available in existing genetic systems, and developing new model systems that more fully represent the diversity of plant morphology.

The Desire for Amputation or Paralyzation: Evidence for Structural Brain Anomalies in Body Integrity Identity Disorder (BIID).

Blom, Rianne M; van Wingen, Guido A; van der Wal, Sija J; Luigjes, Judy; van Dijk, Milenna T; Scholte, H Steven; Denys, Damiaan

2016-01-01

Body Integrity Identity Disorder (BIID) is a condition in which individuals perceive a mismatch between their internal body scheme and physical body shape, resulting in an absolute desire to be either amputated or paralyzed. The condition is hypothesized to be of congenital nature, but evidence for a neuro-anatomical basis is sparse. We collected T1-weighted structural magnetic resonance imaging scans on a 3T scanner in eight individuals with BIID and 24 matched healthy controls, and analyzed the data using voxel-based morphometry. The results showed reduced grey matter volume in the left dorsal and ventral premotor cortices and larger grey matter volume in the cerebellum (lobule VIIa) in individuals with BIID compared to controls. The premotor cortex and cerebellum are thought to be crucial for the experience of body-ownership and the integration of multisensory information. Our results suggest that BIID is associated with structural brain anomalies and might result from a dysfunction in the integration of multisensory information, leading to the feeling of disunity between the mental and physical body shape.

Exploring medical identity theft.

2009-09-16

The crime of medical identity theft is a growing concern in healthcare institutions. A mixed-method study design including a two-stage electronic survey, telephone survey follow-up, and on-site observations was used to evaluate current practices in admitting and registration departments to reduce the occurrence of medical identity theft. Survey participants were chief compliance officers in acute healthcare organizations and members of the Health Care Compliance Association. Study results indicate variance in whether or how patient identity is confirmed in healthcare settings. The findings of this study suggest that information systems need to be designed for more efficient identity management. Admitting and registration staff must be trained, and compliance with medical identity theft policies and procedures must be monitored. Finally, biometric identity management solutions should be considered for stronger patient identification verification.

Patients who suffer from dissociative identity disorder present unique scientific and clinical challenges for psychology and psychiatry. We have been fortunate in working with a patient who-while undergoing functional MRI-can switch rapidly and voluntarily between her main personality (a middle-aged, high-functioning woman) and an alternate personality (a 4-6-year-old girl). A unique task was designed to isolate the processes occurring during the switches between these personalities. Data are from two imaging sessions, conducted months apart, each showing the same activated areas during switches between these personalities. The activated areas include the following: the primary sensory and motor cortex, likely associated with characteristic facial movements made during switching; the nucleus accumbens bilaterally, possibly associated with aspects of reward connected with switching; and prefrontal sites, presumably associated with the executive control involved in the switching of personalities.

Empowering social action through narratives of identity and culture.

2003-03-01

Concern at widening health and wealth inequities between communities accompanying processes of globalization in recent years are reflected in contemporary definitions of health promotion, premised on the stratagem of individuals and communities increasing control over factors that determine health, thereby improving their health status. Such community empowerment practice is commonly accepted within the health promotion literature as encompassing intrapersonal, interpersonal and socio-political elements. Less articulated and understood, however, are the processes whereby the identities and cultures of marginalized communities intersect with and reverberate through these levels of action. The potential of identity and culture as important individual and community resources within social action takes on further significance within global-ized contexts, which simultaneously expose marginalized communities to dominant cultural power relations while affording members new avenues for cultural expression. In this paper we highlight culture and identity as important aspects of the empowerment process, drawing on the experiences of migrant Tongan and Samoan women throughout a social action process in Aotearoa/New Zealand. In particular, narratives of identity and culture within storytelling as an empowerment practice are explicated, as is the articulation of identity and culture within more structurally orientated power relations throughout subsequent activities related to policy advocacy.

Broken identity: the impact of the Holocaust on identity in Romanian and Polish Jews.

PubMed

Prot, Katarzyna

2008-01-01

The paper is based on interviews conducted with Holocaust survivors in Poland (30 interviews) and Romania (55 interviews). It describes how the Holocaust affected survivor identity. Two aspects of identity are analyzed the sense of personal identity and social identity. Each affects the other but they are largely independent and the trauma of the Holocaust impacted each of them differently. Personal identity seems to be unrelated to either the type of trauma or the survivor's social situation. There are no significant differences in that aspect between Polish and Romanian survivors. Social identity is more related to the survivors' social situation prior to and after the trauma. The sense of identity, both personal and social, is dynamic and changes over time.

Coming to an Asexual Identity: Negotiating Identity, Negotiating Desire.

Scherrer, Kristin S

2008-10-01

Sexuality is generally considered an important aspect of self-hood. Therefore, individuals who do not experience sexual attraction, and embrace an asexual identity are in a unique position to inform the social construction of sexuality. This study explores the experiences of asexual individuals utilizing open ended Internet survey data from 102 self-identified asexual people. In this paper I describe several distinct aspects of asexual identities: the meanings of sexual, and therefore, asexual behaviors, essentialist characterizations of asexuality, and lastly, interest in romance as a distinct dimension of sexuality. These findings have implications not only for asexual identities, but also for the connections of asexuality with other marginalized sexualities.

Calcium-Activated Cl- Channel: Insights on the Molecular Identity in Epithelial Tissues.

Rottgen, Trey S; Nickerson, Andrew J; Rajendran, Vazhaikkurichi M

2018-05-10

Calcium-activated chloride secretion in epithelial tissues has been described for many years. However, the molecular identity of the channel responsible for the Ca 2+ -activated Cl − secretion in epithelial tissues has remained a mystery. More recently, TMEM16A has been identified as a new putative Ca 2+ -activated Cl − channel (CaCC). The primary goal of this article will be to review the characterization of TMEM16A, as it relates to the physical structure of the channel, as well as important residues that confer voltage and Ca 2+ -sensitivity of the channel. This review will also discuss the role of TMEM16A in epithelial physiology and potential associated-pathophysiology. This will include discussion of developed knockout models that have provided much needed insight on the functional localization of TMEM16A in several epithelial tissues. Finally, this review will examine the implications of the identification of TMEM16A as it pertains to potential novel therapies in several pathologies.

Vignoles, Vivian L; Manzi, Claudia; Regalia, Camillo; Jemmolo, Simone; Scabini, Eugenia

2008-10-01

Desired and feared possible future selves are important motivators of behavior and provide a temporal context for self-evaluation. Yet little research has examined why people desire some possible selves and fear others. In two studies, we tested the reflection of identity motives for self-esteem, efficacy, meaning, continuity, belonging, and distinctiveness in people's desired and feared possible future selves and in their possible future identity structures. As predicted, participants desired especially those possible futures in which motives for self-esteem, efficacy, meaning, and continuity would be satisfied, and they feared especially those in which the same four motives and, marginally, the motive for distinctiveness would be frustrated. Analyses supported an indirect path from belonging via self-esteem to desire and fear. Desired and feared possible future selves reflect potential satisfaction and frustration of these identity motives.

Gly missense mutations in type I collagen, which replace a conserved Gly in the repeating (Gly-Xaa-Yaa) n sequence with a larger residue, are known to cause Osteogenesis Imperfecta (OI). The clinical consequences of such mutations range from mild to lethal, with more serious clinical severity associated with larger Gly replacement residues. Here, we investigate the influence of the identity of the residue replacing Gly within and adjacent to the integrin binding 502 GFPGER 507 sequence on triple-helix structure, stability and integrin binding using a recombinant bacterial collagen system. Recombinant collagens were constructed with Gly substituted by Ala, Ser or Val at four positions within the integrin binding region. All constructs formed a stable triple-helix structure with a small decrease in melting temperature. Trypsin was used to probe local disruption of the triple helix, and Gly to Val replacements made the triple helix trypsin sensitive at three of the four sites. Any mutation at Gly505, eliminated integrin binding, while decreased integrin binding affinity was observed in the replacement of Gly residues at Gly502 following the order Val > Ser > Ala. Molecular dynamics simulations indicated that all Gly replacements led to transient disruption of triple-helix interchain hydrogen bonds in the region of the Gly replacement. These computational and experimental results lend insight into the complex molecular basis of the varying clinical severity of OI. Copyright © 2018. Published by Elsevier Inc.

Exploring Medical Identity Theft

PubMed Central

Mancilla, Desla; Moczygemba, Jackie

2009-01-01

The crime of medical identity theft is a growing concern in healthcare institutions. A mixed-method study design including a two-stage electronic survey, telephone survey follow-up, and on-site observations was used to evaluate current practices in admitting and registration departments to reduce the occurrence of medical identity theft. Survey participants were chief compliance officers in acute healthcare organizations and members of the Health Care Compliance Association. Study results indicate variance in whether or how patient identity is confirmed in healthcare settings. The findings of this study suggest that information systems need to be designed for more efficient identity management. Admitting and registration staff must be trained, and compliance with medical identity theft policies and procedures must be monitored. Finally, biometric identity management solutions should be considered for stronger patient identification verification. PMID:20169017

Inter-layer synchronization in non-identical multi-layer networks

Inter-layer synchronization is a dynamical process occurring in multi-layer networks composed of identical nodes. This process emerges when all layers are synchronized, while nodes in each layer do not necessarily evolve in unison. So far, the study of such inter-layer synchronization has been restricted to the case in which all layers have an identical connectivity structure. When layers are not identical, the inter-layer synchronous state is no longer a stable solution of the system. Nevertheless, when layers differ in just a few links, an approximate treatment is still feasible, and allows one to gather information on whether and how the system may wander around an inter-layer synchronous configuration. We report the details of an approximate analytical treatment for a two-layer multiplex, which results in the introduction of an extra inertial term accounting for structural differences. Numerical validation of the predictions highlights the usefulness of our approach, especially for small or moderate topological differences in the intra-layer coupling. Moreover, we identify a non-trivial relationship connecting the betweenness centrality of the missing links and the intra-layer coupling strength. Finally, by the use of multiplexed layers of electronic circuits, we study the inter-layer synchronization as a function of the removed links.

Unmasking identity dissonance: exploring medical students' professional identity formation through mask making.

Joseph, Kimera; Bader, Karlen; Wilson, Sara; Walker, Melissa; Stephens, Mark; Varpio, Lara

2017-04-01

Professional identity formation is an on-going, integrative process underlying trainees' experiences of medical education. Since each medical student's professional identity formation process is an individual, internal, and often times emotionally charged unconscious experience, it can be difficult for educators to understand each student's unique experience. We investigate if mask making can provide learners and educators the opportunity to explore medical students' professional identity formation experiences. In 2014 and 2015, 30 third year medical students created masks, with a brief accompanying written narrative, to creatively express their medical education experiences. Using a paradigmatic case selection approach, four masks were analyzed using techniques from visual rhetoric and the Listening Guide. The research team clearly detected identity dissonance in each case. Each case provided insights into the unique personal experiences of the dissonance process for each trainee at a particular point in their medical school training. We propose that mask making accompanied by a brief narrative reflection can help educators identify students experiencing identity dissonance, and explore each student's unique experience of that dissonance. The process of making these artistic expressions may also provide a form of intervention that can enable educators to help students navigate professional identity formation and identity dissonance experiences.

Mercury Fulminate (MF) is one of the well-known primary explosives since 17th century and it has rendered invaluable service over many years. However, the correct molecular and crystal structures are determined recently after 300 years of its discovery. In the present study, we report pressure dependent structural, elastic, electronic and optical properties of MF. Non-local correction methods have been employed to capture the weak van der Waals interactions in layered and molecular energetic MF. Among the non-local correction methods tested, optB88-vdW method works well for the investigated compound. The obtained equilibrium bulk modulus reveals that MF is softer than themore » well known primary explosives Silver Fulminate (SF), silver azide and lead azide. MF exhibits anisotropic compressibility (b > a > c) under pressure, consequently the corresponding elastic moduli decrease in the following order: C{sub 22} > C{sub 11} > C{sub 33}. The structural and mechanical properties suggest that MF is more sensitive to detonate along c-axis (similar to RDX) due to high compressibility of Hg⋯O non-bonded interactions along that axis. Electronic structure and optical properties were calculated including spin-orbit (SO) interactions using full potential linearized augmented plane wave method within recently developed Tran-Blaha modified Becke-Johnson (TB-mBJ) potential. The calculated TB-mBJ electronic structures of SF and MF show that these compounds are indirect bandgap insulators. Also, SO coupling is found to be more pronounced for 4d and 5d-states of Ag and Hg atoms of SF and MF, respectively. Partial density of states and electron charge density maps were used to describe the nature of chemical bonding. Ag—C bond is more directional than Hg—C bond which makes SF to be more unstable than MF. The effect of SO coupling on optical properties has also been studied and found to be significant for both (SF and MF) of the compounds.« less

Self and identity in women with symptoms of borderline personality: A qualitative study.

2016-01-01

Identity disturbance has been suggested to be a core feature of borderline personality disorder (BPD). However, there is little known about the identity of individuals with symptoms of BPD from the participant's perspective. This study availed of in-depth lightly structured life story interviews with five female participants. Thematic analysis was utilized to derive three themes of identity: connection, distance between us, and hurt and healing. Results provided support for multiple and flexible conceptualizations of identity in comparison to the idea of a unitary self/identity. Results also suggested that participants were able to establish differing connections to others ranging from disconnection to intimacy and care. Participants reported that their identities were impacted upon by historical and current family/relationship dysfunction, but life stories also illustrated the positive impact of healing relationship experiences. Findings provide support for psychological theories that consider a multiple and relational self/identity and the empowerment of healthy aspects of the self in BPD recovery. Studies that assess the association between insight and change may further our knowledge into this complex population.

The theory of gender identity disorders.

PubMed

Meyer, J K

1982-01-01

Experience with more than 500 patients over the last decade has led to the conclusion that the quest for sex reassignment is a symptomatic compromise formation serving defensive and expressive functions. The symptoms are the outgrowth of developmental trauma affecting body ego and archaic sense of self and caused by peculiar symbiotic and separation-individuation phase relationships. The child exists in the pathogenic (and reparative) maternal fantasy in order to repair her body image and to demonstrate the interconvertability of the sexes. Gender identity exists not as a primary phenomenon, but in a sense as a tertiary one. There is, no doubt, a tendency to gender-differentiate in a way concordant with biological endowment. Nevertheless, gender formation is seriously compromised by earlier psychological difficulty. Gender identity is a fundamental acquisition in the developing personality, but it is part of a hierarchical series beginning with archaic body ego, early body image, and primitive selfness, representing their extension into sexual and reproductive spheres. Gender identity consolidates during separation-individuation and gender pathology bears common features with other preoedipal syndromes. Transsexualism is closely linked to perversions, and the clinical syndromes may shade from one into another. However, what is kept at the symbolic level in the perversions must be made concrete in transsexualism. In this regard there is a close relation to psychosis. The clinical complaint of the transsexual is a condensation of remarkable proportions. When the transsexual says that he is a girl trapped in a man's body, he sincerely means what he says. As with other symptoms, however, it takes a long time before he begins to say what he means.

An improved purification procedure, including nickel chelate affinity chromatography, is reported which resulted in a crystallizable pyruvate:ferredoxin oxidoreductase preparation from Halobacterium halobium. Crystals of the enzyme were obtained using potassium citrate as the precipitant. The genes coding for pyruvate:ferredoxin oxidoreductase were cloned and their nucleotide sequences determined. The genes of both subunits were adjacent to one another on the halobacterial genome. The derived amino acid sequences were confirmed by partial primary structure analysis of the purified protein. The structural motif of thiamin-diphosphate-binding enzymes was unequivocally located in the deduced amino acid sequence of the small subunit.

Becoming physics people: Development of integrated physics identity through the Learning Assistant experience

NASA Astrophysics Data System (ADS)

Close, Eleanor W.; Conn, Jessica; Close, Hunter G.

2016-06-01

[This paper is part of the Focused Collection on Preparing and Supporting University Physics Educators.] In this study, we analyze the experience of students in the Physics Learning Assistant (LA) program at Texas State University in terms of the existing theoretical frameworks of community of practice and physics identity, and explore the implications suggested by these theories for LA program adoption and adaptation. Regression models from physics identity studies show that the physics identity construct strongly predicts intended choice of a career in physics. The goal of our current project is to understand the details of the impacts of participation in the LA experience on participants' practice and self-concept, in order to identify critical elements of LA program structure that positively influence physics identity and physics career intentions for students. Our analysis suggests that participation in the LA program impacts LAs in ways that support both stronger "physics student" identity and stronger "physics instructor" identity, and that these identities are reconciled into a coherent integrated physics identity. Increased comfort in interactions with peers, near peers, and faculty seems to be an important component of this identity development and reconciliation, suggesting that a focus on supporting community membership is useful for effective program design.

This study inquires into identity alteration among college students and its relationship to borderline personality disorder (BPD) and/or dissociative disorders (DDs). Steinberg Identity Alteration Questionnaire (SIAQ), Childhood Trauma Questionnaire (CTQ), and self-report screening tool of the BPD section of the Structured Clinical Interview for DSM-IV (SCID-BPD) were administered to 1301 college students. Participants who fit the diagnostic criteria of BPD (n = 80) according to the clinician-administered SCID-BPD and 111 non-BPD controls were evaluated using the Structured Clinical Interview for DSM-IV DDs (SCID-D) by two psychiatrists blind to the group membership and scale scores. Test-retest evaluations and internal consistency analyses suggested that SIAQ was a reliable instrument. Of the participants, 11.3% reported a SIAQ score 25 or above alongside some impairment. SIAQ scores differentiated participants who fit the diagnostic criteria for a DD from those who did not. While self-report identity alteration was correlated with all childhood trauma types, clinician-assessed identity alteration was correlated with childhood sexual abuse only. Those who fit criteria for both disorders had the highest identity alteration scores in self-report and clinician-assessment. Although both syndromes had significant effect on self-report identity alteration total scores, in contrast to DD, BPD did not have an effect on the clinician-administered evaluation. An impression of personality disorder rather than a DD may seem more likely when identity alteration remains subtle in clinical assessment, notwithstanding its presence in self-report. Lack of recognition of identity alteration may lead to overdiagnosis of BPD among individuals who have a DD.

Inter-identity autobiographical amnesia in patients with dissociative identity disorder.

Huntjens, Rafaële J C; Verschuere, Bruno; McNally, Richard J

2012-01-01

A major symptom of Dissociative Identity Disorder (DID; formerly Multiple Personality Disorder) is dissociative amnesia, the inability to recall important personal information. Only two case studies have directly addressed autobiographical memory in DID. Both provided evidence suggestive of dissociative amnesia. The aim of the current study was to objectively assess transfer of autobiographical information between identities in a larger sample of DID patients. Using a concealed information task, we assessed recognition of autobiographical details in an amnesic identity. Eleven DID patients, 27 normal controls, and 23 controls simulating DID participated. Controls and simulators were matched to patients on age, education level, and type of autobiographical memory tested. Although patients subjectively reported amnesia for the autobiographical details included in the task, the results indicated transfer of information between identities. The results call for a revision of the DID definition. The amnesia criterion should be modified to emphasize its subjective nature.

2016-03-01

Although dissociative identity disorder (DID), the most severe of the dissociative disorders, has retained its own diagnostic entity since its introduction in the DSM-III, cases of DID are rarely seen in South and East Asia, likely due to the higher prevalence of possession disorder. We report two patients with DID who were recently admitted to our inpatient psychiatric unit and demonstrated distinct transitions to several identities. Their diagnoses were confirmed through a structured interview for dissociative disorders and possible differential diagnoses were ruled out by psychological, neuroimaging, and laboratory tests. The rapid transition to a Westernized, individualized society along with an increase in child abuse, might contribute to an increase in DID, previously under-diagnosed in this region.

Objective. To examine the extent to which reflective essays written by graduating pharmacy students revealed professional identity formation and self-authorship development. Design. Following a six-week advanced pharmacy practice experience (APPE) grounded in Baxter-Magolda's Learning Partnerships Model of self-authorship development, students completed a culminating reflective essay on their rotation experiences and professional identity formation. Assessment. Thematic and categorical analysis of 41 de-identified essays revealed nine themes and evidence of all Baxter-Magolda's domains and phases of self-authorship. Analysis also suggested relationships between self-authorship and pharmacist professional identity formation. Conclusion. Results suggest that purposeful structuring of learning experiences can facilitate professional identity formation. Further, Baxter-Magolda's framework for self-authorship and use of the Learning Partnership Model seem to align well with pharmacist professional identify formation. Results of this study could be used by pharmacy faculty members when considering how to fill gaps in professional identity formation in future course and curriculum development.

Prior research has found that a strong positive ethnic identity is a protective factor against anxiety and depression in African Americans. In this study, ethnic identity is examined in a geographically representative sample of African American young adults (n = 242), using the Multigroup Ethnic Identity Measure (MEIM) (Phinney in J Adolescent Res 7:156-76, 15). The two-factor structure of the measure (Roberts et al. in J Early Adolescence 19:301-22, 1) was analyzed using a structural equation model and displayed an acceptable fit only when multiple error terms were correlated. A multigroup confirmatory factor analysis revealed measurement equivalence of the two-factor structure between African Americans from Southern and non-Southern regions of the USA. We found that significantly higher levels of ethnic identity were present among African American in the South compared to other regions, and region significantly predicted total ethnic identity scores in a linear regression, even when controlling for gender, age, urbanicity, and years of education. Furthermore, among African Americans, living in the South was significantly correlated with less help-seeking for diagnosed depression, anxiety, and/or obsessive-compulsive disorder, where help-seeking was defined as obtaining a diagnosis by a professional. The role of ethnic identity and social support are discussed in the context of African American mental health.

Willingness to Engage in Consensual Nonmonogamy Among Emerging Adults: A Structural Equation Analysis of Sexual Identity, Casual Sex Attitudes, and Gender.

PubMed

Sizemore, Kayla M; Olmstead, Spencer B

2017-01-01

Research on consensual nonmonogamy (CNM) has increased over the past decade. However, willingness to engage in CNM is an understudied phenomenon within this body of literature. Little research has examined the correlates of this aspect of CNM or focused on individuals in the developmental period of emerging adulthood. This study used multigroup structural equation modeling (SEM) to test a conceptual model of emerging adults' (ages 18 to 29; N = 890) willingness to engage in CNM. Results indicated that emerging adult experimentation/possibilities, sexual identity exploration, and permissive attitudes toward casual sex were all related to willingness to engage in CNM. Results also showed that the pathway from emerging adult experimentation/possibilities to willingness to engage in CNM was differentially mediated across gender. Specifically, for women there was an indirect (and positive) pathway from experimentation/possibilities to willingness to engage in CNM through sexual identity exploration. For men there was an indirect (and positive) pathway from experimentation/possibilities to willingness to engage in CNM through permissive attitudes toward casual sex. Implications for future studies on CNM among emerging adults are discussed.

Fridell, Sari R; Owen-Anderson, Allison; Johnson, Laurel L; Bradley, Susan J; Zucker, Kenneth J

The present study compared the sex-typed preferences for playmates and play styles in children referred for concerns about their gender identity development (199 boys, 43 girls) with that of controls (96 boys, 38 girls). Each child was administered the Playmate and Play Style Preferences Structured Interview (PPPSI) developed by Alexander and Hines (Alexander, G. M., & Hines, M. (1994). Child Development, 65, 869-879). In the two single dimension conditions (playmates and play styles), the controls significantly preferred same-sex playmates and same-sex play styles whereas the gender-referred children significantly preferred cross-sex playmates and cross-sex play styles. Effect sizes ranged from 1.56-2.78. In the conflict condition (which required a choice between same-sex playmates and cross-sex play styles vs. cross-sex playmates and same-sex play styles), there was a general indication of a hierarchical preference for the preferred play style in the single dimension condition as opposed to the preferred playmate except for the gender-referred boys, who showed an inverted pattern. For the gender-referred group, the PPPSI data were significantly correlated with other measures of sex-typed behavior, providing evidence of predictive validity. The PPPSI also discriminated between probands threshold and subthreshold for the diagnosis of gender identity disorder. The results were discussed in relation to both basic and applied issues in the assessment of sex-typed behavior in children.

The aim of this study is to explore arguments that broaden the understanding of possible links between the organization of nursing care and the structuring of professional identity. For that purpose, some aspects related to these themes are addressed, highlighting issues regarding differences in the concepts of the organization of nursing care and the nursing process, as well as the performance of this activity and its possible impact on the establishment of its relationship with the professional identity. Emphasis is given to the need to stimulate the debate on the subject by nursing professionals involved in the training of human resources and the provision of care, as well as in class entities, in order to deepen understanding of these concepts as significant elements for strengthening our professional identity.

Spatiotemporal dynamics of similarity-based neural representations of facial identity.

Vida, Mark D; Nestor, Adrian; Plaut, David C; Behrmann, Marlene

2017-01-10

Humans' remarkable ability to quickly and accurately discriminate among thousands of highly similar complex objects demands rapid and precise neural computations. To elucidate the process by which this is achieved, we used magnetoencephalography to measure spatiotemporal patterns of neural activity with high temporal resolution during visual discrimination among a large and carefully controlled set of faces. We also compared these neural data to lower level "image-based" and higher level "identity-based" model-based representations of our stimuli and to behavioral similarity judgments of our stimuli. Between ∼50 and 400 ms after stimulus onset, face-selective sources in right lateral occipital cortex and right fusiform gyrus and sources in a control region (left V1) yielded successful classification of facial identity. In all regions, early responses were more similar to the image-based representation than to the identity-based representation. In the face-selective regions only, responses were more similar to the identity-based representation at several time points after 200 ms. Behavioral responses were more similar to the identity-based representation than to the image-based representation, and their structure was predicted by responses in the face-selective regions. These results provide a temporally precise description of the transformation from low- to high-level representations of facial identity in human face-selective cortex and demonstrate that face-selective cortical regions represent multiple distinct types of information about face identity at different times over the first 500 ms after stimulus onset. These results have important implications for understanding the rapid emergence of fine-grained, high-level representations of object identity, a computation essential to human visual expertise.

Tomboy as protective identity.

PubMed

Craig, Traci; Lacroix, Jessica

2011-01-01

The tomboy in contemporary U.S. culture is a complex identity, providing meaning to many girls and women. In this article, we argue tomboy as a gendered social identity also provides temporary "protections" to girls and women in three main ways. First, tomboy identity can excuse masculine-typed behavior in girls and women and, in doing so, protect women from presumptions about sexual reputation and sexual orientation. Second, tomboy identities can provide some protection for lesbian girls and women who prefer to not divulge their sexual orientation. And, third, tomboy identity can gain women limited privilege to spaces for which masculinity is an unspoken requirement. The temporary nature of the protections provided to tomboys undermines the ability of tomboys to truly transcend the binary gender system.

Plant identity and shallow soil moisture are primary drivers of stomatal conductance in the savannas of Kruger National Park.

Our goal was to describe stomatal conductance (gs) and the site-scale environmental parameters that best predict gs in Kruger National Park (KNP), South Africa. Dominant grass and woody species were measured over two growing seasons in each of four study sites that represented the natural factorial combination of mean annual precipitation [wet (750 mm) or dry (450 mm)] and soil type (clay or sand) found in KNP. A machine-learning (random forest) model was used to describe gs as a function of plant type (species or functional group) and site-level environmental parameters (CO2, season, shortwave radiation, soil type, soil moisture, time of day, vapor pressure deficit and wind speed). The model explained 58% of the variance among 6,850 gs measurements. Species, or plant functional group, and shallow (0-20 cm) soil moisture had the greatest effect on gs. Atmospheric drivers and soil type were less important. When parameterized with three years of observed environmental data, the model estimated mean daytime growing season gs as 68 and 157 mmol m-2 sec-1 for grasses and woody plants, respectively. The model produced here could, for example, be used to estimate gs and evapotranspiration in KNP under varying climate conditions. Results from this field-based study highlight the role of species identity and shallow soil moisture as primary drivers of gs in savanna ecosystems of KNP.

Introduction: Eating disorder symptomatology, comprising both psychological and behavioral aspects of subclinical eating concerns, constitutes a clear precursor of developing eating disorders. It is crucial to investigate its antecedents and correlates to subsequently inform eating disorder prevention programs. The present study focused on identity formation, a core developmental task in adolescence, that has increasingly been linked to eating disorder development. Our main aim was to examine the temporal sequence between eating disorder symptomatology and identity formation. Methods: Data on eating disorder symptomatology and identity formation were collected in 530 high school students (at Time 1: mean age = 15 years; SD = 1.84; range: 12-18 years; 50.6% females) using self-report questionnaires at three annual measurement points. Cross-lagged structural equation modeling was performed to examine the directionality of effects. Results: Results indicated bidirectional effects between eating disorder symptomatology and identity formation. Identity confusion seemed to increase vulnerability to body dissatisfaction and bulimia symptoms, whereas identity synthesis seemed to protect against their development. Additionally, identity synthesis seemed to protect against the development of drive for thinness as well. At the same time, body dissatisfaction and bulimia symptoms positively predicted identity confusion and negatively predicted identity synthesis over time. Conclusion: The present study adds to the growing body of literature on identity and eating disorders by focusing on their temporal interplay in a community sample of adolescents. As bidirectional effects emerged, a greater emphasis on identity formation in eating disorder prevention programs is advocated.

Suarez, J.; Mahon, J.

1991-01-01

The use of innovative cost effective material forms and processes is being considered for fabrication of future primary aircraft structures. Processes that have been identified as meeting these goals are textile preforms that use resin transfer molding (RTM) and consolidation forming. The Novel Composites for Wing and Fuselage Applications (NCWFA) program has as its objective the integration of innovative design concepts with cost effective fabrication processes to develop damage-tolerant structures that can perform at a design ultimate strain level of 6000 micro-inch/inch. In this on-going effort, design trade studies were conducted to arrive at advanced wing designs that integrate new material forms with innovative structural concepts and cost effective fabrication methods. The focus has been on minimizing part count (mechanical fasteners, clips, number of stiffeners, etc.), by using cost effective textile reinforcement concepts that provide improved damage tolerance and out-of-plane load capability, low-cost resin transfer molding processing, and thermoplastic forming concepts. The fabrication of representative Y spars by consolidation methods will be described. The Y spars were fabricated using AS4 (6K)/PEEK 150g commingled angle interlock 0/90-degree woven preforms with +45-degree commingled plies stitched using high strength Toray carbon thread and processed by autoclave consolidation.

The present study was designed to examine the extent to which (a) family and school functioning and (b) personal and ethnic identity is associated with conduct problems, drug use, and sexual risk taking in a sample of 227 high-risk Hispanic adolescents. Adolescents participated in the study with their primary parents, who were mostly mothers. Adolescents completed measures of family and school functioning, personal and ethnic identity, conduct problems, and drug use. Parents completed measures of family functioning and adolescent conduct problems. Results indicated that school functioning and personal identity confusion were related to alcohol use, illicit drug use, and sexual risk taking indirectly through adolescent reports of conduct problems. Adolescent reports of family functioning were related to alcohol use, illicit drug use, and sexual risk taking through school functioning and conduct problems. Results are discussed in terms of the problem behavior syndrome and in terms of the finding of relative independence of contextual and identity variables vis-à-vis conduct problems, substance use, and sexual risk taking.

2012-01-01

Background A major symptom of Dissociative Identity Disorder (DID; formerly Multiple Personality Disorder) is dissociative amnesia, the inability to recall important personal information. Only two case studies have directly addressed autobiographical memory in DID. Both provided evidence suggestive of dissociative amnesia. The aim of the current study was to objectively assess transfer of autobiographical information between identities in a larger sample of DID patients. Methods Using a concealed information task, we assessed recognition of autobiographical details in an amnesic identity. Eleven DID patients, 27 normal controls, and 23 controls simulating DID participated. Controls and simulators were matched to patients on age, education level, and type of autobiographical memory tested. Findings Although patients subjectively reported amnesia for the autobiographical details included in the task, the results indicated transfer of information between identities. Conclusion The results call for a revision of the DID definition. The amnesia criterion should be modified to emphasize its subjective nature. PMID:22815769

Compression strength of composite primary structural components

Johnson, Eric R.

1994-01-01

The linear elastic response is determined for an internally pressurized, long circular cylindrical shell stiffened on the inside by a regular arrangement of identical stringers and identical rings. Periodicity of this configuration permits the analysis of a portion of the shell wall centered over a generic stringer-ring joint; i.e., a unit cell model. The stiffeners are modeled as discrete beams, and the stringer is assumed to have a symmetrical cross section and the ring an asymmetrical section. Asymmetery causes out-of-plane bending and torsion of the ring. Displacements are assumed as truncated double Fourier series plus simple terms in the axial coordinate to account for the closed and pressure vessel effect (a non-periodic effect). The interacting line loads between the stiffeners and the inside shell wall are Lagrange multipliers in the formulation, and they are also assumed as truncated Fourier series. Displacement continuity constraints between the stiffeners and shell along the contact lines are satisfied point-wise. Equilibrium is imposed by the principle of virtual work. A composite material crown panel from the fuselage of a large transport aircraft is the numerical example. The distributions of the interacting line loads, and the out-of-plane bending moment and torque in the ring, are strongly dependent on modeling the deformations due to transverse shear and cross-sectional warping of the ring in torsion. This paper contains the results from the semiannual report on research on 'Pressure Pillowing of an Orthogonally Stiffened Cylindrical Shell'. The results of the new work are illustrated in the included appendix.

Deaf identities in a multicultural setting: The Ugandan context

Atekyereza, Peter R.; Kirumira, Edward K.; Hojer, Staffan

2015-01-01

Often located far apart from each other, deaf and hearing impaired persons face a multiplicity of challenges that evolve around isolation, neglect and the deprivation of essential social services that affect their welfare and survival. Although it is evident that the number of persons born with or acquire hearing impairments in later stages of their lives is increasing in many developing countries, there is limited research on this population. The main objective of this article is to explore the identities and experiences of living as a person who is deaf in Uganda. Using data from semi-structured interviews with 42 deaf persons (aged 19–41) and three focus group discussions, the study findings show that beneath the more pragmatic identities documented in the United States and European discourses there is a matrix of ambiguous, often competing and manifold forms in Uganda that are not necessarily based on the deaf and deaf constructions. The results further show that the country's cultural, religious and ethnic diversity is more of a restraint than an enabler to the aspirations of the deaf community. The study concludes that researchers and policy makers need to be cognisant of the unique issues underlying deaf epistemologies whilst implementing policy and programme initiatives that directly affect them. The upper case ‘D’ in the term deaf is a convention that has been used since the early 1970s to connote a ‘socially constructed visual culture’ or a linguistic, social and cultural minority group who use sign language as primary means of communication and identify with the deaf community, whereas the lower case ‘d’ in deaf refers to ‘the audio logical condition of hearing impairment’. However, in this article the lower case has been used consistently. PMID:28730015

Women in physics? Identity and discourse in Taiwan

NASA Astrophysics Data System (ADS)

Tsai, Li-Ling

This dissertation argues that the deeply held hope for gender equity in science can no longer be simply realized as a project to increase women's participation in science. Understanding women's vexed relations with science requires a reconceptualization of the terms women and science, not as given categories to signal how "women" are coping with their disadvantaged positions in "science," but rather as two discourses formed in relation to each other, in institutional practices and in particular social and historical contexts. This dissertation investigates discourses of women and science by focusing on women in physics in Taiwan. This focus extends debates about gender and science by showing that the intervention of a particular discourse---in this case, the discourse of "women in physics"---into an existing discursive field exposed the contested terrain of the gender politics of physics and the identity politics of women physicists in Taiwan. "Women in physics" emerged as an internationally legitimate subject position in Taiwan in 1999 following a call to form a local working team on women in physics. The participants I interviewed utilized this internationally legitimate subject position to reconstruct, in different ways, their gendered identities in physics. Scholarship in the field of gender and science education studies has, over the past three decades, focused on equity and inclusion to address gender inequalities in science. This dissertation suggests, by contrast, that a focus on identity is necessary for understanding gendered career decisions in science. The term identity refers to how individuals perceive themselves and how others respond to their claims; identity involves the purposes, interests and contexts of particular naming processes. In the structural inequalities of gender and science, a focus on identity aims to track individual and collective forms of agency exercised in changing discursive fields. This dissertation concludes by viewing

2014-02-01

A renewed interest in identity as one of the core markers of personality disorders has been introduced by the DSM-5 Level of Personality Functioning Scale. However, little is known about the utility of the construct of identity in children and adolescents. This study aimed to broaden the knowledge of identity integration as a core component of personality functioning in adolescents. The authors investigated levels of identity integration, as measured by the Severity Indices of Personality Problems (SIPP-118; Verheul et al., 2008), in adolescents in both normal (n = 406) and clinical populations (n = 285). Furthermore, changes in levels of identity integration during treatment were investigated in a clinical subsample (n = 76). Levels of identity integration were not associated with age. They were, however, associated with the absence or presence of personality pathology. Most adolescents receiving inpatient psychotherapy gradually changed toward more healthy levels of identity integration; a significant number, however, remained at maladaptive levels of identity functioning after intensive psychotherapy.

Structure of Cellulose Microfibrils in Primary Cell Walls from Collenchyma1[C][W][OA

In the primary walls of growing plant cells, the glucose polymer cellulose is assembled into long microfibrils a few nanometers in diameter. The rigidity and orientation of these microfibrils control cell expansion; therefore, cellulose synthesis is a key factor in the growth and morphogenesis of plants. Celery (Apium graveolens) collenchyma is a useful model system for the study of primary wall microfibril structure because its microfibrils are oriented with unusual uniformity, facilitating spectroscopic and diffraction experiments. Using a combination of x-ray and neutron scattering methods with vibrational and nuclear magnetic resonance spectroscopy, we show that celery collenchyma microfibrils were 2.9 to 3.0 nm in mean diameter, with a most probable structure containing 24 chains in cross section, arranged in eight hydrogen-bonded sheets of three chains, with extensive disorder in lateral packing, conformation, and hydrogen bonding. A similar 18-chain structure, and 24-chain structures of different shape, fitted the data less well. Conformational disorder was largely restricted to the surface chains, but disorder in chain packing was not. That is, in position and orientation, the surface chains conformed to the disordered lattice constituting the core of each microfibril. There was evidence that adjacent microfibrils were noncovalently aggregated together over part of their length, suggesting that the need to disrupt these aggregates might be a constraining factor in growth and in the hydrolysis of cellulose for biofuel production.

The sense of identity and symptoms of personality disorders - The results of a non-clinical population study.

PubMed

Pilarska, Aleksandra; Suchańska, Anna

2015-01-01

The aim of the presented studies was to empirically analyze the relation between the symptoms of personality disorders and the structure of identity-related senses. The analyses were conducted within two models - based on Millon's theory of personality and DSM-IV personality disorder classification system. In the studies, a total of 197 university students of various majors were included. The authors used Polish version of the Millon Index of Personality Styles that assess personality styles and offers a Clinical Index to evaluate psychological adjustment, and Personality Disorder Types Questionnaire to obtain DSM-IV diagnoses. The intensity of the identity-related senses was measured using the Multidimensional Identity Inventory. Data were tested for normality, and then Student's t-tests and ANOVA tests were used to compare the structure of identity-related senses in individuals with a healthy personality and disordered personality. Within Millon's model, three different patterns of disordered personality were found, and they all manifested some identity deficits. Most of the personality disorders covered by DSM-IV also significantly differed on the identity dimensions from healthy personality. The results show that identity deficits should be considered as an important symptom of personality disorders, regardless of the adopted model of personality. The most disordered identity is observed in individuals falling into the group with odd or eccentric disorders and into the anxious or fearful cluster. The group with dramatic, emotional or erratic disorders is the most heterogeneous in terms of the level of identity disorganization.

The amino acid sequence and glycan structure of PD-L1, PD-L2 and PD-L3, type 1 ribosome-inactivating proteins isolated from Phytolacca dioica L. leaves, were determined using a combined approach based on peptide mapping, Edman degradation and ESI-Q-TOF MS in precursor ion discovery mode. The comparative analysis of the 261 amino acid residue sequences showed that PD-L1 and PD-L2 have identical primary structure, as it is the case of PD-L3 and PD-L4. Furthermore, the primary structure of PD-Ls 1-2 and PD-Ls 3-4 have 81.6% identity (85.1% similarity). The ESI-Q-TOF MS analysis confirmed that PD-Ls 1-3 were glycosylated at different sites. In particular, PD-L1 contained three glycidic chains with the well known paucidomannosidic structure (Man)(3) (GlcNAc)(2) (Fuc)(1) (Xyl)(1) linked to Asn10, Asn43 and Asn255. PD-L2 was glycosylated at Asn10 and Asn43, and PD-L3 was glycosylated only at Asn10. PD-L4 was confirmed to be not glycosylated. Despite an overall high structural similarity, the comparative modeling of PD-L1, PD-L2, PD-L3 and PD-L4 has shown potential influences of the glycidic chains on their adenine polynucleotide glycosylase activity on different substrates.

The structuring of identity among midlife women as a function of their degree of involvement in employment.

Hornstein, G A

1986-09-01

The place of employment and the diversity of its relations to other roles within the life structure of midlife women were investigated. Three groups were compared: Group I (n = 44) had a continuous low level of involvement in employment from their early 20s to their early 40s; Group II (n = 20) changed from low to high involvement; and Group III (n = 32) maintained a continuous high level of involvement. Retrospective reports regarding subjects' commitment to a number of different roles and feelings during their early 30s and early 40s constituted the data. Findings indicated that: (1) women in Group I had a positive, confident view of their involvement in the traditional roles of mother, wife, and volunteer; (2) women in Group II, initially quite similar to those in Group I, restructured their role commitments by substituting involvement in employment for more traditional pursuits; and (3) women in Group III successfully integrated involvement in the multiple roles of worker, mother, wife, and volunteer. Implications for a more dynamic view of identity, which takes into account significant reorganization of the life structure after adolescence and variability among diverse groups of women, are discussed.

Community preceptors' views of their identities as teachers.

Community physicians are increasingly being recruited to teach medical students and residents, yet there has been little research about how they think of themselves as teachers or what factors contribute to "teacher identity." Physicians who think of themselves as teachers may be more likely to enjoy teaching, to teach more, and to be recognized by students and other faculty as good teachers. Identifying factors that enhance teacher identity may be helpful for the recruitment and retention of high-quality community faculty. Thirty-five experienced community preceptors were audiotaped in five structured focus groups in April 2001, answering a series of questions about their teacher identity. Responses were qualitatively analyzed for evidence of themes. "Feeling intrinsic satisfaction" was the most common theme that emerged from the tapes. Preceptors also identified that "having knowledge and skill about teaching" and "belonging to a group of teacher" enhanced their roles as teachers. "Being a physician means being a teacher," "feeling a responsibility to teach medicine," and "sharing clinical expertise" also emerged as important themes. Although a group of participants were interested in "receiving rewards for teaching," rewards did not need to be financial compensation. For some, genuine recognition for their efforts by the medical school, particularly in the form of faculty development opportunities, constituted reward and recognition for teaching. Community physicians described a variety of factors that contribute to their identity as teachers. Faculty development programs offer opportunities to strengthen teacher identity and foster relationships between teaching programs and community-based faculty.

Tools for Understanding Identity

Creese, Sadie; Gibson-Robinson, Thomas; Goldsmith, Michael

Identity attribution and enrichment is critical to many aspects of law-enforcement and intelligence gathering; this identity typically spans a number of domains in the natural-world such as biographic information (factual information – e.g. names, addresses), biometric information (e.g. fingerprints) and psychological information. In addition to these natural-world projections of identity, identity elements are projected in the cyber-world. Conversely, undesirable elements may use similar techniques to target individuals for spear-phishing attacks (or worse), and potential targets or their organizations may want to determine how to minimize the attack surface exposed. Our research has been exploring the construction of a mathematical modelmore » for identity that supports such holistic identities. The model captures the ways in which an identity is constructed through a combination of data elements (e.g. a username on a forum, an address, a telephone number). Some of these elements may allow new characteristics to be inferred, hence enriching the holistic view of the identity. An example use-case would be the inference of real names from usernames, the ‘path’ created by inferring new elements of identity is highlighted in the ‘critical information’ panel. Individual attribution exercises can be understood as paths through a number of elements. Intuitively the entire realizable ‘capability’ can be modeled as a directed graph, where the elements are nodes and the inferences are represented by links connecting one or more antecedents with a conclusion. The model can be operationalized with two levels of tool support described in this paper, the first is a working prototype, the second is expected to reach prototype by July 2013: Understanding the Model The tool allows a user to easily determine, given a particular set of inferences and attributes, which elements or inferences are of most value to an investigator (or an attacker).

Perceived consequences of hypothetical identity-inconsistent sexual experiences: effects of perceiver's sex and sexual identity.

Most people organize their sexual orientation under a single sexual identity label. However, people may have sexual experiences that are inconsistent with their categorical sexual identity label. A man might identify as heterosexual but still experience some attraction to men; a woman might identify as lesbian yet enter into a romantic relationship with a man. Identity-inconsistent experiences are likely to have consequences. In the present study, we examined lay perceptions of the consequences of identity-inconsistent sexual experiences for self-perceived sexuality and for social relationships among a sexually diverse sample (N = 283). We found that the perceived consequences of identity-inconsistent experiences for self-perception, for social stigmatization, and for social relationships varied as a function of participant sex, participant sexual identity (heterosexual, gay, lesbian), and experience type (fantasy, attraction, behavior, love). We conclude that not all identity-inconsistent sexual experiences are perceived as equally consequential and that the perceived consequences of such experiences vary predictably as a function of perceiver sex and sexual identity. We discuss the role lay perceptions of the consequences of identity-inconsistent sexual experiences may play in guiding attitudes and behavior.

The association of personal semantic memory to identity representations: insight into higher-order networks of autobiographical contents.

PubMed

Grilli, Matthew D

2017-11-01

Identity representations are higher-order knowledge structures that organise autobiographical memories on the basis of personality and role-based themes of one's self-concept. In two experiments, the extent to which different types of personal semantic content are reflected in these higher-order networks of memories was investigated. Healthy, young adult participants generated identity representations that varied in remoteness of formation and verbally reflected on these themes in an open-ended narrative task. The narrative responses were scored for retrieval of episodic, experience-near personal semantic and experience-far (i.e., abstract) personal semantic contents. Results revealed that to reflect on remotely formed identity representations, experience-far personal semantic contents were retrieved more than experience-near personal semantic contents. In contrast, to reflect on recently formed identity representations, experience-near personal semantic contents were retrieved more than experience-far personal semantic contents. Although episodic memory contents were retrieved less than both personal semantic content types to reflect on remotely formed identity representations, this content type was retrieved at a similar frequency as experience-far personal semantic content to reflect on recently formed identity representations. These findings indicate that the association of personal semantic content to identity representations is robust and related to time since acquisition of these knowledge structures.

`All We Did was Things Like Forces and Motion …': Multiple Discourses in the development of primary science teachers

NASA Astrophysics Data System (ADS)

Danielsson, Anna; Warwick, Paul

2014-01-01

Previous research has highlighted challenges associated with embracing an inquiry approach to science teaching for primary teachers, often associating these challenges with insecurity linked to the lack of content knowledge. We argue that in order to understand the extent to which primary student teachers are able to embrace science teaching informed by scientific literacy for all, it is important to take into account various, sometimes competing, science teacher and primary teacher Discourses. The aim of this paper is to explore how such Discourses are constituted in the context of learning to teach during a 1-year university-based Post Graduate Certificate of Education course. The empirical data consist of semi-structured interviews with 11 student teachers. The analysis identifies 5 teacher Discourses and we argue that these can help us to better understand some of the tensions involved in becoming a primary teacher with a responsibility for teaching science: for example, in terms of the interplay between the student teachers' own educational biographies and institutionally sanctioned Discourses. One conclusion is that student teachers' willingness and ability to embrace a Discourse of science education, informed by the aim of scientific literacy for all, may be every bit as constrained by their experience of learning science through 'traditional schooling' as it is by their confidence with respect to their own subject knowledge. The 5 Discourses, with their complex interrelations, raise questions about which identity positions are available to students in the intersections of the Discourses and which identity positions teacher educators may seek to make available for their students.

Intersections between immigration, language, identity, and emotions: a science teacher candidate's journey

This study reports a subset of findings from a larger, ongoing study aimed at exploring interactions between teacher identity, learning, and classroom practices in a social justice teacher education program at a selective liberal arts college in New York. This case-study explores the journey of Elena, as an immigrant, a student, and a pre-service teacher candidate towards becoming a social justice educator. Elena reflects upon her school language experiences as an immigrant youth, her learning in a social justice teacher education program, and her field experiences in an international high school. The analysis spans macro-, meso-, and microlevels to explore the ways globalization, particularly immigration, as well as schooling policies for English language learners interact with aspects of Elena's core identity, particularly in school settings. The findings show some of the ways language and literacy verified and/or denied aspects of Elena's core identity; specific instances where second language proficiency was cast as power and privilege versus disadvantage according to ethnic, language, and class categorizations; and the struggles Elena, and other immigrant youth may face given the focus on English language acquisition and high stakes accountability in schools, at the expense of students' primary language proficiency and affirmation of core identity markers.

Authentic feminist? Authenticity and feminist identity in teenage feminists' talk.

PubMed

Calder-Dawe, Octavia; Gavey, Nicola

2017-12-01

This article explores how young people's feminist identities take shape in conjunction with a contemporary ideal of personal authenticity: to know and to express the 'real me'. Drawing from interviews with 18 teenagers living in Auckland, New Zealand, we examine a novel convergence of authenticity and feminism in participants' identity talk. For social psychologists interested in identity and politics, this convergence is intriguing: individualizing values such as authenticity are generally associated with disengagement with structural critique and with a repudiation of politicized and activist identities. Rather than seeking to categorize authentic feminism as an instance of either 'good/collective' or 'bad/individualized' feminist politics, we use discourse analysis to examine how the identity position of authentic feminist was constructed and to explore implications for feminist politics. On one hand, interviewees mobilized authentic feminism to affirm their commitment to normative liberal values of authenticity and self-expression. At the same time, the position of authentic feminist appeared to authorize risky feminist identifications and to justify counter-normative feelings, desires, and actions. To conclude, we explore how encountering others' intolerance of authentic feminism exposed interviewees to the limits of authenticity discourse, propelling some towards new understandings of the social world and their space for action within it. © 2017 The British Psychological Society.

The aim of the study was to investigate if there were any characteristics of regional cerebral blood flow (rCBF) in dissociative identity disorder. Twenty-one drug-free patients with dissociative identity disorder and nine healthy volunteers participated in the study. In addition to a clinical evaluation, dissociative psychopathology was assessed using the Structured Clinical Interview for DSM-IV Dissociative Disorders, the Dissociative Experiences Scale and the Clinician-Administered Dissociative States Scale. A semi-structured interview for borderline personality disorder, the Hamilton Depression Rating Scale, and the Childhood Trauma Questionnaire were also administered to all patients. Normal controls had to be without a history of childhood trauma and without any depressive or dissociative disorder. Regional cerebral blood flow (rCBF) was studied with single photon emission computed tomography (SPECT) with Tc99m-hexamethylpropylenamine (HMPAO) as a tracer. Compared with findings in the control group, the rCBF ratio was decreased among patients with dissociative identity disorder in the orbitofrontal region bilaterally. It was increased in median and superior frontal regions and occipital regions bilaterally. There was no significant correlation between rCBF ratios of the regions of interest and any of the psychopathology scale scores. An explanation for the neurophysiology of dissociative psychopathology has to invoke a comprehensive model of interaction between anterior and posterior brain regions.

In recent years, the main focus of health sector reforms in Iran is the family physician and referral system plan. Fundamental changes in the goals and strategies, has increased the necessity of the need to reform the organizational structure. This study tries to review and summarize all cases about the organizational structure of Iran and its challenges in primary health care system. This study was a systematic review of published and grey literature. We searched the relevant databases, bibliography of related papers, and laws, using appropriate search strategies and key words. The CASP tool was used by two experts to evaluate the quality of retrieved papers and inconsistencies were resolved by discussion. After removal of duplicate citations, a total of 52 titles were identified through database searching, among which 30 met the inclusion criteria. Considering the research quality criteria, 14 papers were recognized qualified, which were categorized into two groups of: articles and policies. The results showed ineffectiveness of the current organizational structure at different level. The majority of the papers recommend performing reforms in the system because of changes in goals and strategies. Also, some suggest an appropriate information system to be designed in the current structures. Centralization and delegation process are the main discussions for the studies. Because of fundamental changes in goals and strategies, reforms in the organizational structure of primary health system in Iran especially in peripheral levels are highly recommended.

Perceptions of parents' ethnic identities and the personal ethnic-identity and racial attitudes of biracial adults.

The present study examined the relationship of perceived parental closeness and parental ethnic identity on personal ethnic identity and colorblindness beliefs in 275 part-White biracial Americans (M age = 23.88). Respondents completed online measures of their personal ethnic identity (minority, White, and multiracial), perceived parental ethnic identity, parental closeness, and attitudes about the state of race relations and the need for social action in the United States. Using path modeling, results show that part-White biracial individuals perceive their ethnic identity to be strongly linked to their parental racial identities, especially when they had closer parental relationships. Moreover, stronger minority identity was linked to less colorblind attitudes, and greater White identity was linked to greater colorblind attitudes suggesting that patterns of identity may influence how biracial individuals view race-relations and the need for social action. Implications for biracial well-being and their understanding of prejudice and discrimination are discussed. (PsycINFO Database Record (c) 2015 APA, all rights reserved).

Online Identities and Social Networking

Maheswaran, Muthucumaru; Ali, Bader; Ozguven, Hatice; Lord, Julien

Online identities play a critical role in the social web that is taking shape on the Internet. Despite many technical proposals for creating and managing online identities, none has received widespread acceptance. Design and implementation of online identities that are socially acceptable on the Internet remains an open problem. This chapter discusses the interplay between online identities and social networking. Online social networks (OSNs) are growing at a rapid pace and has millions of members in them. While the recent trend is to create explicit OSNs such as Facebook and MySpace, we also have implicit OSNs such as interaction graphs created by email and instant messaging services. Explicit OSNs allow users to create profiles and use them to project their identities on the web. There are many interesting identity related issues in the context of social networking including how OSNs help and hinder the definition of online identities.

The objective of this study is to investigate whether the characteristics of the structure of primary health units and the work process of primary care teams are associated with the number of hospitalizations for primary care sensitive conditions. In this ecological study, we have analyzed data of Brazilian municipalities related to sociodemographic characteristics, coverage of care programs, structure of primary health units, and work process of primary care teams. We have obtained the data from the first cycle of the Brazilian Program for Improving Access and Quality of the Primary Care, of the Department of Information Technology of the Brazilian Unified Health System, the Brazilian Institute of Geography and Statistics, and the United Nations Development Programme. The associations have been estimated using negative binomial regression coefficients (β) and respective 95% confidence intervals, with a hierarchical approach in three levels (alpha = 5%). In the adjusted analysis for the outcome in 2013, in the distal level, the coverage of the Bolsa Família Program (β = -0.001) and private insurance (β = -0.01) had a negative association, and the human development index (β = 1.13), the proportion of older adults (β = 0.05) and children under the age of five (β = 0.05), and the coverage of the Community Health Agent Strategy (β = 0.002) showed positive association with hospitalizations for primary care sensitive conditions. In the intermediate level, minimum hours (β = -0.14) and availability of vaccines (β = -0.16) showed a negative association, and availability of medications showed a positive association (β = 0.16). In the proximal level, only the variable of matrix support (β = 0.10) showed a positive association. The variables in the adjusted analysis of the number of hospitalizations for primary care sensitive conditions in 2014 presented the same association as in 2013.

Primary care has potential to play a role for improving the patient care in Japanese health care system; however, little information is available about how patients perceive the roles of primary care physicians (PCPs) within the Japanese health care system. We aimed to assess population-level preferences for PCPs and investigated the extent to which preferences vary in relation to different population groups in Japan. Data were extracted from a cross-sectional questionnaire survey in October 2003. An 18-item questionnaire was used to measure the preferences for PCPs. Exploratory factor analysis was performed to identify latent factors, while confirmatory factor analysis was used to evaluate the fit of the structure using structural equation modeling (SEM). Nationally representative sample of the adult Japanese general population was chosen by controlling for age, sex, and the size of cities. A total of 2,453 adults>or=18-years-old were analyzed. SEM provided a 4-factor structural model of the population-level preference for PCPs, such as clinical competence (path coefficient (pc)=0.72), gate-keeping (pc=0.64), communication with patients or specialists (pc=0.49) and high education (pc=0.25) and demonstrated the best goodness-of-fit. Those who were middle aged, have a high family income, and a high level of education, placed more importance on gate-keeping characteristics, and the rural residents emphasized communication rather than clinical competence. Our results indicate that the preferences for PCPs are divided into four main factors and underscore the variation among preferences according to different population groups, such as age, socioeconomic and educational status, and places of living. These variations should be considered to improve the primary care system in Japan.

Lockwood on human identity and the primitive streak.

1997-01-01

Michael Lockwood has recently concluded that it can be morally permissible to perform potentially damaging non-therapeutic experiments on live human (pre)embryos. The reasons he provides in support of this conclusion commit him inter alia to the following controversial theses: (i) an organism's potential for twinning bears critically on the identity conditions for that organism; and (ii) functionally intact mentality-mediating neurological structures play a critical role in establishing the identity conditions for human organisms. I argue that Lockwood has given us no good reason to endorse either of these theses and, hence, that he has given us no good reason to believe that it can be morally permissible to perform potentially damaging non-therapeutic experiments on live human (pre)embryos.

Patients with borderline personality disorder (BPD) show various psychopathological symptoms and suffer especially from disturbance in their identity. The purpose of the study was to investigate changes-particularly in affective BPD symptoms and identity diffusion-during a structured, disorder-specific inpatient treatment (DST) that combined a psychodynamic transference-focused psychotherapy approach with modules of dialectical behavioural skills training. In a prospective, two-group comparison trial, 44 patients with BPD were assessed with questionnaires addressing identity diffusion and state, as well as trait affective psychopathology, before and after 12 weeks of inpatient treatment. Thirty-two patients received DST, whereas 12 patients were given inpatient treatment-as-usual (TAU). The patients were allocated in a non-random procedure for two groups, in order of admission and availability of treatment options in the DST unit. In the pre-post-comparison, the DST group showed a significant decrease in identity diffusion (p < 0.001) and improvements in instability of the image of self and others (p < 0.008), as well as in pathological (trait and state) symptoms. However, there was no significant improvement in the TAU group. After a 12-week inpatient treatment, the findings indicate significant improvements in the DST group in typical affective borderline symptomatology and in the personality structure feature of identity diffusion. This highlights the significance of a short-term specific inpatient therapy for BPD. A structured, disorder-specific inpatient treatment of patients diagnosed with borderline personality disorder (BPD) combined a psychodynamic transference-focused psychotherapy treatment approach (focusing on pathological features in personality organization, particularly on non-integrated images of self and others) with modules of dialectical behavioural skills training. This treatment is associated with a decrease in identity diffusion of
