2017-01-01

The current study examined the frequency with which randomized controlled trials (RCTs) of behavioral and psychological interventions for anxiety and depression include data pertaining to participant sexual orientation and nonbinary gender identities. Using systematic review methodology, the databases PubMed and PsycINFO were searched to identify RCTs published in 2004, 2009, and 2014. Random selections of 400 articles per database per year (2,400 articles in total) were considered for inclusion in the review. Articles meeting inclusion criteria were read and coded by the research team to identify whether the trial reported data pertaining to participant sexual orientation and nonbinary gender identities. Additional trial characteristics were also identified and indexed in our database (e.g., sample size, funding source). Of the 232 articles meeting inclusion criteria, only 1 reported participants' sexual orientation, and zero articles included nonbinary gender identities. A total of 52,769 participants were represented in the trials, 93 of which were conducted in the United States, and 43 acknowledged the National Institutes of Health as a source of funding. Despite known mental health disparities on the basis of sexual orientation and nonbinary gender identification, researchers evaluating interventions for anxiety and depression are not reporting on these important demographic characteristics. Reporting practices must change to ensure that our interventions generalize to lesbian, gay, bisexual, and transgender persons. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

CILogon translates mechanism and policy across higher education and grid trust federations, bridging from the InCommon identity federation (which federates university and DOE lab identities) to the Interoperable Global Trust Federation (which defines standards across the Worldwide LHC Computing Grid, the Open Science Grid, and other cyberinfrastructure). The CILogon-HA project expanded the CILogon service to support over 160 identity providers (including 6 DOE facilities) andmore » 3 internationally accredited certification authorities. To provide continuity of operations upon the end of the CILogon-HA project period, project staff transitioned the CILogon service to operation by XSEDE.« less

Talker identification across source mechanisms: experiments with laryngeal and electrolarynx speech.

PubMed

Perrachione, Tyler K; Stepp, Cara E; Hillman, Robert E; Wong, Patrick C M

2014-10-01

The purpose of this study was to determine listeners' ability to learn talker identity from speech produced with an electrolarynx, explore source and filter differentiation in talker identification, and describe acoustic-phonetic changes associated with electrolarynx use. Healthy adult control listeners learned to identify talkers from speech recordings produced using talkers' normal laryngeal vocal source or an electrolarynx. Listeners' abilities to identify talkers from the trained vocal source (Experiment 1) and generalize this knowledge to the untrained source (Experiment 2) were assessed. Acoustic-phonetic measurements of spectral differences between source mechanisms were performed. Additional listeners attempted to match recordings from different source mechanisms to a single talker (Experiment 3). Listeners successfully learned talker identity from electrolarynx speech but less accurately than from laryngeal speech. Listeners were unable to generalize talker identity to the untrained source mechanism. Electrolarynx use resulted in vowels with higher F1 frequencies compared with laryngeal speech. Listeners matched recordings from different sources to a single talker better than chance. Electrolarynx speech, although lacking individual differences in voice quality, nevertheless conveys sufficient indexical information related to the vocal filter and articulation for listeners to identify individual talkers. Psychologically, perception of talker identity arises from a "gestalt" of the vocal source and filter.

Tagmouti, Saloua; Slater, Madeline; Benedetti, Andrea; Kik, Sandra V.; Banaei, Niaz; Cattamanchi, Adithya; Metcalfe, John; Dowdy, David; van Zyl Smit, Richard; Dendukuri, Nandini

2014-01-01

Rationale: Interferon gamma (IFN-γ) release assays for latent tuberculosis infection result in a larger-than-expected number of conversions and reversions in occupational screening programs, and reproducibility of test results is a concern. Objectives: Knowledge of the relative contribution and extent of the individual sources of variability (immunological, preanalytical, or analytical) could help optimize testing protocols. Methods: We performed a systematic review of studies published by October 2013 on all potential sources of variability of commercial IFN-γ release assays (QuantiFERON-TB Gold In-Tube and T-SPOT.TB). The included studies assessed test variability under identical conditions and under different conditions (the latter both overall and stratified by individual sources of variability). Linear mixed effects models were used to estimate within-subject SD. Measurements and Main Results: We identified a total of 26 articles, including 7 studies analyzing variability under the same conditions, 10 studies analyzing variability with repeat testing over time under different conditions, and 19 studies reporting individual sources of variability. Most data were on QuantiFERON (only three studies on T-SPOT.TB). A considerable number of conversions and reversions were seen around the manufacturer-recommended cut-point. The estimated range of variability of IFN-γ response in QuantiFERON under identical conditions was ±0.47 IU/ml (coefficient of variation, 13%) and ±0.26 IU/ml (30%) for individuals with an initial IFN-γ response in the borderline range (0.25–0.80 IU/ml). The estimated range of variability in noncontrolled settings was substantially larger (±1.4 IU/ml; 60%). Blood volume inoculated into QuantiFERON tubes and preanalytic delay were identified as key sources of variability. Conclusions: This systematic review shows substantial variability with repeat IFN-γ release assays testing even under identical conditions, suggesting that reversions and conversions around the existing cut-point should be interpreted with caution.

Intergenerational transmission of ethnic identity and life satisfaction of Roma minority adolescents and their parents.

PubMed

Dimitrova, Radosveta; Ferrer-Wreder, Laura; Trost, Kari

2015-12-01

This study investigates intergeneration transmission of ethnic identity as a resource for life satisfaction of Roma adolescents and their parents. Historically, Roma represent the largest ethnic minority in Europe. They have been exposed to severe discrimination, social exclusion, and poverty. Therefore, identifying resources for their life satisfaction is theoretically and practically important. The present study included 1093 participants, of which there were 171 Roma adolescents (age: M = 14.96 years, SD = 1.85), 155 mothers (age: M = 36.16 years, SD = 5.77) and 123 fathers (age: M = 39.68 years, SD = 6.06). Further, a comparison group of 248 mainstream adolescents with their mothers (n = 221) and fathers (n = 175) was also included in the study. Adolescents and their parents provided data on ethnic identity (MEIM; Phinney, 1992) and life satisfaction (SWLS; Diener, Emmons, Larsen, & Griffin, 1985). Results indicated that Roma youth were lower on endorsement of ethnic identity and average on life satisfaction compared to their mainstream peers. A structural equation model showed that ethnic identity was a positive predictor of life satisfaction for both adolescents and their Roma parents. Furthermore, parents' ethnic identity was a predictor of adolescent life satisfaction. We concluded that for Roma youth and their parents, ethnic identity represents a salient source for life satisfaction and an intergenerational continuity of identity and life satisfaction exists.

Bennett, Keisa; Ricks, JaNelle M.; Howell, Britteny M.

2014-01-01

Lesbian, gay, and bisexual (LGB) people are affected by multiple health disparities and risk factors, including tobacco use. Few studies to date have examined tobacco use specifically in rural LGB populations, and none has investigated the intersections of identity, rural LGB culture, and tobacco. The purpose of this study was to explore the perspective of Appalachian LGB people regarding tobacco use. Methods Nineteen LGB-identified Appalachian residents participated in audiotaped, semi-structured interviews. Two authors analyzed and coded transcripts through constant comparison, and determined themes through consensus. Results Five themes emerged: the convergence of Appalachian and LGB identities, tacit awareness of LGB identity by others, culture and tobacco use, perceived associations with tobacco use, and health beliefs and health care. Conclusions LGB Appalachians connect stress and culture to tobacco, but seem less aware that partial concealment of their identity might be a source of the stress that could influence their smoking.

Analysis of Discontinuities in a Rectangular Waveguide Using Dyadic Green's Function Approach in Conjunction with Method of Moments

NASA Technical Reports Server (NTRS)

Deshpande, M. D.

1997-01-01

The dyadic Green's function for an electric current source placed in a rectangular waveguide is derived using a magnetic vector potential approach. A complete solution for the electric and magnetic fields including the source location is obtained by simple differentiation of the vector potential around the source location. The simple differentiation approach which gives electric and magnetic fields identical to an earlier derivation is overlooked by the earlier workers in the derivation of the dyadic Green's function particularly around the source location. Numerical results obtained using the Green's function approach are compared with the results obtained using the Finite Element Method (FEM).

Contralateral delay activity tracks object identity information in visual short term memory.

PubMed

Gao, Zaifeng; Xu, Xiaotian; Chen, Zhibo; Yin, Jun; Shen, Mowei; Shui, Rende

2011-08-11

Previous studies suggested that ERP component contralateral delay activity (CDA) tracks the number of objects containing identity information stored in visual short term memory (VSTM). Later MEG and fMRI studies implied that its neural source lays in superior IPS. However, since the memorized stimuli in previous studies were displayed in distinct spatial locations, hence possibly CDA tracks the object-location information instead. Moreover, a recent study implied the activation in superior IPS reflected the location load. The current research thus explored whether CDA tracks the object-location load or the object-identity load, and its neural sources. Participants were asked to remember one color, four identical colors or four distinct colors. The four-identical-color condition was the critical one because it contains the same amount of identity information as that of one color while the same amount of location information as that of four distinct colors. To ensure the participants indeed selected four colors in the four-identical-color condition, we also split the participants into two groups (low- vs. high-capacity), analyzed late positive component (LPC) in the prefrontal area, and collected participant's subjective-report. Our results revealed that most of the participants selected four identical colors. Moreover, regardless of capacity-group, there was no difference on CDA between one color and four identical colors yet both were lower than 4 distinct colors. Besides, the source of CDA was located in the superior parietal lobule, which is very close to the superior IPS. These results support the statement that CDA tracks the object identity information in VSTM. Copyright © 2011 Elsevier B.V. All rights reserved.

Positive and negative ion beam merging system for neutral beam production

DOEpatents

Leung, Ka-Ngo; Reijonen, Jani

2005-12-13

The positive and negative ion beam merging system extracts positive and negative ions of the same species and of the same energy from two separate ion sources. The positive and negative ions from both sources pass through a bending magnetic field region between the pole faces of an electromagnet. Since the positive and negative ions come from mirror image positions on opposite sides of a beam axis, and the positive and negative ions are identical, the trajectories will be symmetrical and the positive and negative ion beams will merge into a single neutral beam as they leave the pole face of the electromagnet. The ion sources are preferably multicusp plasma ion sources. The ion sources may include a multi-aperture extraction system for increasing ion current from the sources.

"FAILING GIRLS": Understanding Connections among Identity Negotiation, Personal Relevance, and Engagement in Science Learning from Underachieving Girls

NASA Astrophysics Data System (ADS)

Thompson, Jessica J.; Windschitl, Mark

Contemporary critiques of science education have noted that girls often fail to engage in science learning because the activities lack relevance for them, and they cannot "see themselves" in the work of science. Despite the empirical support for these claims, theory around the important connections between relevance, emerging self-identity, and engagement for girls remains underdeveloped. This qualitative, exploratory investigation examines engagement in science learning among five underachieving high school girls. Data sources include in-depth interviews, classroom observations, and teacher surveys. The girls were asked to describe engagement within three learning contexts: science class, a favorite class, and an extracurricular activity. From the girls' voices emerge three themes reflecting the centrality of self: "who I am," "who I am becoming," and "the importance of relationships." It is important that these themes of self and of identity negotiation are integrated with the ways these girls find learning personally relevant. One pattern of extracurricular engagement and two patterns of science engagement (integrated and situational) are described. This study attempts to expand the dialogue around the relationships between identity, relevance, and engagement among underachieving girls and suggests ways in which curriculum can be grounded in students' lives and developing identities.

Data Hemorrhages in the Health-Care Sector

NASA Astrophysics Data System (ADS)

Johnson, M. Eric

Confidential data hemorrhaging from health-care providers pose financial risks to firms and medical risks to patients. We examine the consequences of data hemorrhages including privacy violations, medical fraud, financial identity theft, and medical identity theft. We also examine the types and sources of data hemorrhages, focusing on inadvertent disclosures. Through an analysis of leaked files, we examine data hemorrhages stemming from inadvertent disclosures on internet-based file sharing networks. We characterize the security risk for a group of health-care organizations using a direct analysis of leaked files. These files contained highly sensitive medical and personal information that could be maliciously exploited by criminals seeking to commit medical and financial identity theft. We also present evidence of the threat by examining user-issued searches. Our analysis demonstrates both the substantial threat and vulnerability for the health-care sector and the unique complexity exhibited by the US health-care system.

Hispanic women's preferences for breast health information: subjective cultural influences on source, message, and channel.

PubMed

Oetzel, John; De Vargas, Felicia; Ginossar, Tamar; Sanchez, Christina

2007-01-01

The purpose of this study was to investigate the influence of 3 subjective cultural variables--self-construals (independence and interdependence), ethnic identity (bicultural, assimilation, traditional, and marginal), and cultural health attributions (equity and behavioral-environmental attributions)--on source, message, and channel preferences for receiving breast health information by Hispanic women age 35 or older. Subjective cultural variables collectively accounted for 2% to 28% of the variance in communication preferences. In addition, several associations were discovered: (a) having an interdependent self-construal was associated positively with preferences for significant other as a source, family sources, fear messages, media channels, and face-to-face channels; (b) having a bicultural identity was associated positively with preferences for family sources and media channels, but negatively with a desire for no information; and (c) having a marginal identity and equity attributions were associated positively with preferences for fear messages and a desire for no information, but negatively with preferences for expert sources. These findings are discussed in the context of tailoring breast health information to Hispanic women using computer technology and entertainment-education.

Impact of interpersonal relations on learning and development of professional identity: A study of residents' perceptions.

PubMed

Blouin, Danielle

2018-06-01

Informal learning includes all occurrences during one's life when learning is not deliberate. Prior research on informal learning in healthcare contexts examined learning happening outside of the formal curriculum, yet still in the workplace. This study explores residents' perceptions about extracurricular factors outside of the workplace that contribute to their learning and development of professional identity, whether interpersonal relations are recognised as such factors, and positive and negative impacts of interpersonal relations. In this qualitative study, all 21 residents in our Emergency Medicine programme were asked, in a web-based survey with open-ended questions, to identify extracurricular sources outside of the workplace perceived as contributing to their learning and professional identity development, and list positive and negative impacts of interpersonal relations outside of work on learning and identity development. Themes were extracted through content analysis of the narrative responses. Two reviewers coded all data. Thirteen (62%) residents identified 37 factors grouped under five themes: learning activity, role modelling, support, non-clinical academic roles, and social interactions. Interpersonal relations were perceived as having positive and negative impacts, including creating support, positive role modelling and mentoring, increasing concrete learning, as well as lapses in teaching skills, deficits in professional role training, and loss of personal time. Several extracurricular factors outside of the workplace contribute to resident learning and identity development, including interpersonal relations, which have positive and negative impacts. The most often noted negative impact of interpersonal relations outside of work between residents and faculty related to perceived lapses in teaching skills. © 2018 Australasian College for Emergency Medicine and Australasian Society for Emergency Medicine.

Drawing on materials retrieved through a multilayered research strategy comprising internal and external sources, this article examines the development of a nursing identity in Chile during the period starting in the 1950s through the early 2000s. We analysed the sociopolitical contexts in which the nursing profession grew, the changing direction of its role and how the nursing identity transformed itself. Through the use of historical sources and oral testimonies, we aim to give a nuanced account of how the history of public health and that of the country more broadly changed the object of identification of nurses, creating only relatively recently a sense of nursing community. Processes of identification, fragmentation and integration are highlighted, which challenge usual notions of history as a linear process. © 2017 John Wiley & Sons Ltd.

SAVAH: Source Address Validation with Host Identity Protocol

NASA Astrophysics Data System (ADS)

Kuptsov, Dmitriy; Gurtov, Andrei

Explosive growth of the Internet and lack of mechanisms that validate the authenticity of a packet source produced serious security and accounting issues. In this paper, we propose validating source addresses in LAN using Host Identity Protocol (HIP) deployed in a first-hop router. Compared to alternative solutions such as CGA, our approach is suitable both for IPv4 and IPv6. We have implemented SAVAH in Wi-Fi access points and evaluated its overhead for clients and the first-hop router.

Generalisation of the identity method for determination of high-order moments of multiplicity distributions with a software implementation

NASA Astrophysics Data System (ADS)

Maćkowiak-Pawłowska, Maja; Przybyła, Piotr

2018-05-01

The incomplete particle identification limits the experimentally-available phase space region for identified particle analysis. This problem affects ongoing fluctuation and correlation studies including the search for the critical point of strongly interacting matter performed on SPS and RHIC accelerators. In this paper we provide a procedure to obtain nth order moments of the multiplicity distribution using the identity method, generalising previously published solutions for n=2 and n=3. Moreover, we present an open source software implementation of this computation, called Idhim, that allows one to obtain the true moments of identified particle multiplicity distributions from the measured ones provided the response function of the detector is known.

Understanding help-seeking amongst university students: the role of group identity, stigma, and exposure to suicide and help-seeking

Background: Despite a high prevalence of suicide ideation and mental health issues amongst university students, the stigma of help-seeking remains a barrier to those who are in real need of professional support. Social identity theory states that help received from an ingroup source is more welcome and less threatening to one's identity than that from a source perceived as outgroup. Therefore, we hypothesized that students' stigma toward seeking help from their university mental health service would differ based on the strength of their identification with the university. Method: An online survey including measures of stigma of suicide, group identification, experience with help-seeking and exposure to suicide was administered to Irish university students (N = 493). Results: Group identification was a significant predictor of help-seeking attitudes after controlling for already known predictors. Contrary to our expectations, those who identified more strongly with their university demonstrated a higher stigma of seeking help from their university mental health service. Conclusions: Results are discussed in relation to self-categorization theory and the concept of normative fit. Practical implications for mental health service provision in universities are also addressed, specifically the need for a range of different mental health services both on and off-campus.

Methods, systems and apparatus for generating atomic traps, and for storing, controlling and transferring information between first and second spatially separated phase-coherent objects, or using a single phase-coherent object. For plural objects, both phase-coherent objects have a macroscopic occupation of a particular quantum state by identical bosons or identical BCS-paired fermions. The information may be optical information, and the phase-coherent object(s) may be Bose-Einstein condensates, superfluids, or superconductors. The information is stored in the first phase-coherent object at a first storage time and recovered from the second phase-coherent object, or the same first phase-coherent object, at a second revival time. In one example, an integrated silicon wafer-based optical buffer includes an electrolytic atom source to provide the phase-coherent object(s), a nanoscale atomic trap for the phase-coherent object(s), and semiconductor-based optical sources to cool the phase-coherent object(s) and provide coupling fields for storage and transfer of optical information.

Finding meaning in science: Lifeworld, identity, and self

NASA Astrophysics Data System (ADS)

Kozoll, Richard H.; Osborne, Margery D.

2004-03-01

Despite the many hours students spend studying science, only a few relate to these subjects in such a manner that it becomes a part of their essential worldview and advances their education in a larger sense - one in which they make a connection to the subject matter so that it becomes a source of inspiration and occupies a formative position in their life. Using the hermeneutic/phenomenological sense of lifeworld as our being in the world, we explore questions of identity in the teaching and learning of science. We suggest that by taking the notion of identity in science to include students' identities in their collective, inclusive of an orientation toward both who the student is and who he wants to become, we can enable this broader educative process. Science's link to lifeworld, identity, and self as well as the literature surrounding each are treated separately in the context of empirical case studies drawn from interviews with young college-aged migrant agricultural workers. This population of students is living within a distinct culture where ideological systems are spread across lines of ethnicity, class, and vocation that place this population of students at risk of dropping out of school. Given the nature of their circumstances and their desire to leave the life of migration behind, these students show how their perceptions of science are embedded within particular issues of lifeworld, identity, and self while illustrating their interrelationships.

Transgender individuals are vulnerable to negative health risks and outcomes, but research remains limited because data sources, such as electronic medical records (EMRs), lack standardized collection of gender identity information. Most EMR do not include the gold standard of self-identified gender identity, but International Classification of Diseases (ICDs) includes diagnostic codes indicating transgender-related clinical services. However, it is unclear if these codes can indicate transgender status. The objective of this study was to determine the extent to which patients' clinician notes in EMR contained transgender-related terms that could corroborate ICD-coded transgender identity. Data are from the US Department of Veterans Affairs Corporate Data Warehouse. Transgender patients were defined by the presence of ICD9 and ICD10 codes associated with transgender-related clinical services, and a 3:1 comparison group of nontransgender patients was drawn. Patients' clinician text notes were extracted and searched for transgender-related words and phrases. Among 7560 patients defined as transgender based on ICD codes, the search algorithm identified 6753 (89.3%) with transgender-related terms. Among 22 072 patients defined as nontransgender without ICD codes, 246 (1.1%) had transgender-related terms; after review, 11 patients were identified as transgender, suggesting a 0.05% false negative rate. Using ICD-defined transgender status can facilitate health services research when self-identified gender identity data are not available in EMR.

Forensic document analysis using scanning microscopy

Shaffer, Douglas K.

2009-05-01

The authentication and identification of the source of a printed document(s) can be important in forensic investigations involving a wide range of fraudulent materials, including counterfeit currency, travel and identity documents, business and personal checks, money orders, prescription labels, travelers checks, medical records, financial documents and threatening correspondence. The physical and chemical characterization of document materials - including paper, writing inks and printed media - is becoming increasingly relevant for law enforcement agencies, with the availability of a wide variety of sophisticated commercial printers and copiers which are capable of producing fraudulent documents of extremely high print quality, rendering these difficult to distinguish from genuine documents. This paper describes various applications and analytical methodologies using scanning electron miscoscopy/energy dispersive (x-ray) spectroscopy (SEM/EDS) and related technologies for the characterization of fraudulent documents, and illustrates how their morphological and chemical profiles can be compared to (1) authenticate and (2) link forensic documents with a common source(s) in their production history.

[Gender identity, a factor of inequality forgotten by Spanish health information systems].

PubMed

Gil-Borrelli, Christian; Velasco, César; Martí-Pastor, Marc; Latasa, Pello

The Spanish Health Information System (HIS) collects health information. Trans people have poorer health status. This paper aimed to assess the adequacy of the HIS to collect the health data on trans individuals. The HIS sources available in the Statistical Portal of the National Health System were reviewed. The sources containing population health data were selected. The variables "sex" and "gender identity" were searched. Nineteen sources were identified. In all of them the variable "sex" was found, whereas "gender identify" did not appear in any of the 19. In two sources, the variable "sex" allowed values of "transsexual". The SIS contains little information regarding gender identity. This leads to the invisibility of trans people in Spanish health statistics. Obtaining this information would allow for a better understanding of the barriers to health care access, and the health needs of one of the most discriminated groups in our society.

The value of identity: olfactory notes on orbitofrontal cortex function.

PubMed

Gottfried, Jay A; Zelano, Christina

2011-12-01

Neuroscientific research has emphatically promoted the idea that the key function of the orbitofrontal cortex (OFC) is to encode value. Associative learning studies indicate that OFC representations of stimulus cues reflect the predictive value of expected outcomes. Neuroeconomic studies suggest that the OFC distills abstract representations of value from discrete commodities to optimize choice. Although value-based models provide good explanatory power for many different findings, these models are typically disconnected from the very stimuli and commodities giving rise to those value representations. Little provision is made, either theoretically or empirically, for the necessary cooperative role of object identity, without which value becomes orphaned from its source. As a step toward remediating the value of identity, this review provides a focused olfactory survey of OFC research, including new work from our lab, to highlight the elemental involvement of this region in stimulus-specific predictive coding of both perceptual outcomes and expected values. © 2011 New York Academy of Sciences.

Bridges or Barriers? Conceptualization of the Role of Multiple Identity Gateway Groups in Intergroup Relations.

Levy, Aharon; Saguy, Tamar; Halperin, Eran; van Zomeren, Martijn

2017-01-01

The modern era of globalization has been accompanied by a massive growth in interconnections between groups, and has led to the sharing of multiple identities by individuals and groups. Following these developments, research has focused on the issue of multiple identities, and has shed important light on how individuals who hold these complex forms of identity feel and behave, and on the reactions they elicit from members of other groups. However, the potential of groups with such multiple identities (e.g., biracials, immigrants, etc.) to affect the intergroup relations between the groups that represent the respective sources of the different identities (e.g., Blacks and Whites, country of origin and country of residence, etc.) has not been examined to date. Accordingly, in this paper, we first systematically explore the potential of groups in which people identify with multiple social categories, or groups that are perceived as such by others, to play a role in intergroup dynamics. Next, we offer a theoretical framework outlining what functions groups of people with shared multiple identities may serve (as bridges or barriers ) by proposing how their presence may facilitate or deteriorate intergroup relations. Finally, we present recent empirical research examining how groups of people with shared multiple identities can act as gateways and bridge the cleft between two separate groups that represent the respective sources of their different identities, and discuss the theoretical and practical implications for the field of intergroup relations.

In the paper, based on the modified Riemann-Liouville fractional derivative and Tu scheme, the fractional super NLS-MKdV hierarchy is derived, especially the self-consistent sources term is considered. Meanwhile, the generalized fractional supertrace identity is proposed, which is a beneficial supplement to the existing literature on integrable system. As an application, the super Hamiltonian structure of fractional super NLS-MKdV hierarchy is obtained.

Behavioural indicators of motives for barroom aggression: implications for preventing bar violence.

2011-09-01

To develop new strategies for preventing violence in high-risk licensed premises, we identify behavioural indicators of apparent motives for aggression in these settings and outline the implications of different motivations for prevention. The four types of motives for aggressive or coercive acts defined by the theory of coercive actions framed the research: gaining compliance, expressing grievances/restoring justice, attaining a favourable social identity and pursuing fun/excitement. Incidents of aggression from the Safer Bars evaluation research were analysed to identify behavioural indicators of each motivation. Compliance-motivated aggression typically takes the form of unwanted social overtures, third party intervention to stop conflicts or staff rule enforcement. Prevention strategies include keeping the aggressor's focus on compliance to avoid provoking grievance and identity motives that are likely to escalate aggression. Grievance motives are typically elicited by perceived wrongdoing and therefore prevention should focus on eliminating sources of grievances and adopting policies/practices to resolve grievances peacefully. Social identity motives are endemic to many drinking establishments especially among male patrons and staff. Prevention involves reducing identity cues in the environment, hiring staff who do not have identity concerns, and training staff to avoid provoking identity concerns. Aggression motivated by fun/excitement often involves low-level aggression where escalation can be prevented by avoiding grievances and attacks on identity. Knowledge of behavioural indicators of motives can be used to enhance staff hiring and training practices, reduce environmental triggers for aggression, and develop policies to reduce motivation for aggression. © 2011 Australasian Professional Society on Alcohol and other Drugs.

Pharmaceutical identifier confirmation via DART-TOF.

PubMed

Easter, Jacob L; Steiner, Robert R

2014-07-01

Pharmaceutical analysis comprises a large amount of the casework in forensic controlled substances laboratories. In order to reduce the time of analysis for pharmaceuticals, a Direct Analysis in Real Time ion source coupled with an accurate mass time-of-flight (DART-TOF) mass spectrometer was used to confirm identity. DART-TOF spectral data for pharmaceutical samples were analyzed and evaluated by comparison to standard spectra. Identical mass pharmaceuticals were differentiated using collision induced dissociation fragmentation, present/absent ions, and abundance comparison box plots; principal component analysis (PCA) and linear discriminant analysis (LDA) were used for differentiation of identical mass mixed drug spectra. Mass assignment reproducibility and robustness tests were performed on the DART-TOF spectra. Impacts on the forensic science community include a decrease in analysis time over the traditional gas chromatograph/mass spectrometry (GC/MS) confirmations, better laboratory efficiency, and simpler sample preparation. Using physical identifiers and the DART-TOF to confirm pharmaceutical identity will eliminate the use of GC/MS and effectively reduce analysis time while still complying with accepted analysis protocols. This will prove helpful in laboratories with large backlogs and will simplify the confirmation process. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

Despite increasing rates of HIV infection among heterosexual women in Peru, married women remain virtually invisible as a group at risk of HIV or requiring treatment. This study analyzed the intersections of HIV with machismo and marianismo, the dominant discourses in Latin America that prescribe gender roles for men and women. Data sources include recent literature on machismo and marianismo and interviews conducted with 14 HIV-positive women in Lima, Peru. Findings indicate how the stigma associated with HIV constructs a discourse that restricts the identities of HIV-positive women to those of ‘fallen women’ whether or not they adhere to social codes that shape and inform their identities as faithful wives and devoted mothers. Lack of public discourse concerning HIV-positive marianas silences women as wives and disenfranchises them as mothers, leaving them little room to negotiate identities that allow them to maintain their respected social positions. Efforts must be aimed at expanding the discourse of acceptable gender roles and behaviour for both men and women within the context of machismo and marianismo so that there can be better recognition of all persons at risk of, and living with, HIV infection.

2012-03-01

We here present the jmzReader library: a collection of Java application programming interfaces (APIs) to parse the most commonly used peak list and XML-based mass spectrometry (MS) data formats: DTA, MS2, MGF, PKL, mzXML, mzData, and mzML (based on the already existing API jmzML). The library is optimized to be used in conjunction with mzIdentML, the recently released standard data format for reporting protein and peptide identifications, developed by the HUPO proteomics standards initiative (PSI). mzIdentML files do not contain spectra data but contain references to different kinds of external MS data files. As a key functionality, all parsers implement a common interface that supports the various methods used by mzIdentML to reference external spectra. Thus, when developing software for mzIdentML, programmers no longer have to support multiple MS data file formats but only this one interface. The library (which includes a viewer) is open source and, together with detailed documentation, can be downloaded from http://code.google.com/p/jmzreader/. © 2012 WILEY-VCH Verlag GmbH & Co.

Identity development in pre-service teachers who are explainers in a science center: Dialectically developing theory and praxis

NASA Astrophysics Data System (ADS)

Gupta, Preeti

This dissertation investigates how teaching in a hands-on science center contributes to re/shaping one's teaching identity. Situated at the New York Hall of Science (NYHS) in Queens, New York, my research approach is to conduct a critical ethnography where the focus is on improving the teaching and learning of science for all involved. In particular, Explainers, floor staff at NYHS, who are studying to be science teachers, are invited to become co-researchers with me. Written as a manuscript style, this dissertation consists of six chapters. Each chapter foregrounds certain events and phenomena, and theory and method are woven in to theorize identity construction. Grounded in cultural sociology, the frameworks of Cultural Historical Activity Theory (CHAT), and the sociology of emotions, illuminate key understandings about the construction of teaching identity. Multiple data sources including field notes, transcribed audio and videotapes, and cogenerative dialogues are used. I employ a hermeneutic phenomenological approach to data analysis. This research has salient implications for museum-university partnerships, and training for museum floor staff and has the potential to inform policy-making for pre-service teaching clinical fieldwork experiences.

Hoover, R. B.; Underwood, J. H. (Inventor)

1973-01-01

A collimator is disclosed for examining the spatial location of distant sources of radiation and for imaging by projection, small, near sources of radiation. The collimator consists of a plurality of plates, all of which are pierced with an identical random array of apertures. The plates are mounted perpendicular to a common axis, with like apertures on consecutive plates axially aligned so as to form radiation channels parallel to the common axis. For near sources, the collimator is interposed between the source and a radiation detector and is translated perpendicular to the common axis so as to project radiation traveling parallel to the common axis incident to the detector. For far sources the collimator is scanned by rotating it in elevation and azimuth with a detector to determine the angular distribution of the radiation from the source.

Thermal control coatings and contaminant collector mirrors were exposed on the leading and trailing edge modules of Long Duration Exposure Facility (LDEF) experiment A0034 to provide a basis of comparison for investigating the role of atomic oxygen in the stimulation of volatile outgassing products. The exposure of identical thermal coatings on both the leading and trailing edges of the LDEF and the additional modified exposure of identical coatings under glass windows and metallic covers in each of the flight modules provided multiple combinations of space environmental exposure to the coatings and the contaminant collector mirrors. Investigations were made to evaluate the effects of the natural space and the induced environments on the thermal coatings and the collector mirrors to differentiate the sources of observed material degradation. Two identical flight units were fabricated for the LDEF mission, each of which included twenty-five thermal control coatings mounted in isolated compartments, each with an adjacent contaminant collector mirror mounted on the wall. The covers of the flight units included apertures for each compartment, exposing the thermal coatings directly to the space environment. Six of these compartments were sealed with ultraviolet-grade transmitting quartz windows and four other compartments were sealed with aluminum covers. One module of this passive LDEF experiment, occupying one-sixth of a full tray, was mounted in Tray C9 (leading edge), while the other identical module was mounted in Tray C3 (trailing edge).

The social context of motorcycle riding and the key determinants influencing rider behavior: a qualitative investigation.

2011-08-01

Given the increasing popularity of motorcycle riding and heightened risk of injury or death associated with being a rider, this study explored rider behavior as a determinant of rider safety and, in particular, key beliefs and motivations that influence such behavior. To enhance the effectiveness of future education and training interventions, it is important to understand riders' own views about what influences how they ride. Specifically, this study sought to identify key determinants of riders' behaviors in relation to the social context of riding, including social and identity-related influences relating to the group (group norms and group identity) as well as the self (moral/personal norm and self-identity). Qualitative research was undertaken via group discussions with motorcycle riders (n = 41). The findings revealed that those in the group with which one rides represent an important source of social influence. Also, the motorcyclist (group) identity was associated with a range of beliefs, expectations, and behaviors considered to be normative. Exploration of the construct of personal norm revealed that riders were most cognizant of the "wrong things to do" when riding; among those issues raised was the importance of protective clothing (albeit for the protection of others and, in particular, pillion passengers). Finally, self-identity as a motorcyclist appeared to be important to a rider's self-concept and was likely to influence on-road behavior. Overall, the insight provided by the current study may facilitate the development of interventions including rider training as well as public education and mass media messages. The findings suggest that these interventions should incorporate factors associated with the social nature of riding in order to best align it with some of the key beliefs and motivations underpinning riders' on-road behaviors.

Social support in the workplace for physicians in specialization training

2018-01-01

ABSTRACT When becoming a specialist, learning-through-service plays a significant role. The workplace affords good opportunities for learning, but the service-learning period may also impose stress on phycisians in specialization training. In medical work, social support has proved to be a very important factor in managing stress. Social support may afford advantages also for learning and professional identity building. However, little was known about how social support is perceived by doctors in specialization training. This study aimed to understand the perceptions of physicians in specialization training regarding social support communication in their workplace during their learning-through-service period. The study was conducted qualitatively by inductively analyzing the physicians’ descriptions of workplace communication. The dataset included 120 essays, 60 each from hospitals and primary healthcare centres. Physicians in specialization training explained the need of social support with the responsibilities and demands of their clinical work and the inability to control and manage their workloads. They perceived that social support works well for managing stress, but also for strengthening relational ties and one’s professional identity.

When becoming a specialist, learning-through-service plays a significant role. The workplace affords good opportunities for learning, but the service-learning period may also impose stress on phycisians in specialization training. In medical work, social support has proved to be a very important factor in managing stress. Social support may afford advantages also for learning and professional identity building. However, little was known about how social support is perceived by doctors in specialization training. This study aimed to understand the perceptions of physicians in specialization training regarding social support communication in their workplace during their learning-through-service period. The study was conducted qualitatively by inductively analyzing the physicians' descriptions of workplace communication. The dataset included 120 essays, 60 each from hospitals and primary healthcare centres. Physicians in specialization training explained the need of social support with the responsibilities and demands of their clinical work and the inability to control and manage their workloads. They perceived that social support works well for managing stress, but also for strengthening relational ties and one's professional identity. A leader's support was perceived as being effective, and both senior and junior colleagues were described as an important source of social support. Also co-workers, such as the individual nurse partner with whom one works, was mentioned as an important source of social support. The results of this study indicate that social support works at the relational and identity levels, which is due to the multi-functional nature of workplace communication. For example, consultation functions as situational problem-solving, but also the tone of social interaction is meaningful. Thus, strengthening one's professional identity or collegial relationships requires further attention to workplace communication. Abbreviations PiST: Physician in specialization training.

L-asparaginases are widely distributed enzymes among plants, fungi and bacteria. This enzyme catalyzes the conversion of l-asparagine to l-aspartate and ammonia and to a lesser extent the formation of l-glutamate from l-glutamine. In the present study, forty-five full-length amino acid sequences of L-asparaginases from bacteria, fungi and plants were collected and subjected to multiple sequence alignment (MSA), domain identification, discovering individual amino acid composition, and phylogenetic tree construction. MSA revealed that two glycine residues were identically found in all analyzed species, two glycine residues were also identically found in all the fungal and bacterial sources and three glycine residues were identically found in all plant and bacterial sources while no residue was identically found in plant and fungal L-asparaginases. Two major sequence clusters were constructed by phylogenetic analysis. One cluster contains eleven species of fungi, twelve species of bacteria, and one species of plant, whereas the other one contains fourteen species of plant, four species of fungi and three species bacteria. The amino acid composition result revealed that the average frequency of amino acid alanine is 10.77 percent that is very high in comparison to other amino acids in all analyzed species.

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.

Revealing sources and chemical identity of iron ligands across the California Current System

NASA Astrophysics Data System (ADS)

Boiteau, R.; Repeta, D.; Fitzsimmons, J. N.; Parker, C.; Twining, B. S.; Baines, S.

2016-02-01

The California Current System is one of the most productive regions of the ocean, fueled by the upwelling of nutrient rich water. Differences in the supply of micronutrient iron to surface waters along the coast lead to a mosaic of iron-replete and iron-limited conditions across the region, affecting primary production and community composition. Most of the iron in this region is supplied by upwelling of iron from the benthic boundary layer that is complexed by strong organic ligands. However, the source, identity, and bioavailability of these ligands are unknown. Here, we used novel hyphenated chromatography mass spectrometry approaches to structurally characterize organic ligands across the region. With these methods, iron ligands are detected with liquid chromatography coupled to inductively coupled plasma mass spectrometry (LC-ICPMS), and then their mass and fragmentation spectra are determined by high resolution electrospray ionization mass spectrometry (LC-ESIMS). Iron isotopic exchange was used to compare the relative binding strengths of different ligands. Our survey revealed a broad range of ligands from multiple sources. Benthic boundary layers and anoxic sediments were sources of structurally amorphous weak ligands, likely organic degradation products, as well as siderophores, strong iron binding molecules that facilitate iron acquisition. In the euphotic zone, marine microbes and zooplankton grazing produced a wide distribution of other compounds that included known and novel siderophores. This work demonstrates that the chemical nature of ligands from different sources varies substantially and has important implications for iron biogeochemical cycling and availability to members of the microbial community.

HFT events - Shallow moonquakes. [High-Frequency Teleseismic

NASA Technical Reports Server (NTRS)

Nakamura, Y.

1977-01-01

A few large distant seismic events of distinctly high signal frequency, designated HFT (high-frequency teleseismic) events, are observed yearly by the Apollo lunar seismic network. Their sources are located on or near the surface of the moon, leaving a large gap in seismic activity between the zones of HFT sources and deep moonquakes. No strong regularities are found in either their spatial or temporal distributions. Several working hypotheses for the identity of these sources have advanced, but many characteristics of the events seem to favor a hypothesis that they are shallow moonquakes. Simultaneous observations of other lunar phenomena may eventually enable the determination of their true identity.

Effect of the spectrum of a high-intensity sound source on the sound-absorbing properties of a resonance-type acoustic lining

Experimental results are presented on the effect of both the sound pressure level and the type of spectrum of a sound source on the impedance of an acoustic lining. The spectra under study include those of white noise, a narrow-band signal, and a signal with a preset waveform. It is found that, to obtain reliable data on the impedance of an acoustic lining from the results of interferometric measurements, the total sound pressure level of white noise or the maximal sound pressure level of a pure tone (at every oscillation frequency) needs to be identical to the total sound pressure level of the actual source at the site of acoustic lining on the channel wall.

Beyond pain and protection: politics of identity and iban girls in Korea.

This study analyzes the complexities in the exploration of iban girls' identities and the various ways how girls appropriate varied sources such as popular culture to examine the heterogeneousness of identity explorations and rethink the politics of identities. Against the tendency in current discourse on homosexual youth in Korea, protection discourse and pain discourse, the notion of identity itself will be critically examined and the girls' agency in destabilizing heteronormativity will be discussed. This study also deals with the appropriation of popular culture by the girls, suggesting that cultural critiques should reveal complex dynamics in concrete experiences. doi:10.1300/J155v10n03_04.

We present a general purpose, open-source software library for estimation of non-linear parameters by the Levenberg-Marquardt algorithm. The software, Gpufit, runs on a Graphics Processing Unit (GPU) and executes computations in parallel, resulting in a significant gain in performance. We measured a speed increase of up to 42 times when comparing Gpufit with an identical CPU-based algorithm, with no loss of precision or accuracy. Gpufit is designed such that it is easily incorporated into existing applications or adapted for new ones. Multiple software interfaces, including to C, Python, and Matlab, ensure that Gpufit is accessible from most programming environments. The full source code is published as an open source software repository, making its function transparent to the user and facilitating future improvements and extensions. As a demonstration, we used Gpufit to accelerate an existing scientific image analysis package, yielding significantly improved processing times for super-resolution fluorescence microscopy datasets.

Familiarity, legitimation, and frequency: the influence of others on the criminal self-view.

PubMed

Asencio, Emily K

2011-01-01

From an identity theory perspective, reflected appraisals from others are relevant for social behavior, because behavior is motivated by the desire to achieve congruence between reflected appraisals and the self-view for a particular identity. This study extends prior identity theory work from the laboratory setting by examining identity processes with respect to the criminal identity in the unique “natural” setting of a total institution. The findings build on prior work which finds that reflected appraisals do have an influence on identities and behavior by demonstrating that the relationship one has to the source of reflected appraisals is important for the way in which reflected appraisals influence the criminal self-view for an incarcerated population.

"Being on Both Sides": Canadian Medical Students' Experiences With Disability, the Hidden Curriculum, and Professional Identity Construction.

Medical students with disabilities hold firsthand knowledge as healthcare recipients, yet face barriers to disclosure and support. Their experiences provide a unique lens for understanding professional identity construction; therefore, this study explored how disabled medical students experience training as both patients and trainees. The authors conducted qualitative interviews with 10 medical students at the University of Toronto Faculty of Medicine with self-identified disabilities. They performed textual analysis of documents concerning medical student wellness from 13 Canadian universities, including policies, student services, and student blogs (July 2016 to March 2017). Using principles of critical discourse analysis, the authors coded the interviews and texts to identify operating discourses and core themes, drawing from sociocultural theories of professional identity construction and the hidden curriculum. Two dominant discourses emerged from the interviews and texts, revealing institutionalized notions of the perceived "good student" and "good patient." These roles held contradictory demands, demonstrating how institutions often implicitly and explicitly framed wellness as a means to optimal academic performance. Two additional themes, "identity compartmentalization" and "identity intersection," captured students' experiences navigating identities as patients and trainees. Although students lacked explicit opportunities to express their expertise as patients in the formal curriculum, their experiences in both roles led to improved communication, advocacy, and compassion. Institutional discourses around disability and academic performance hold material implications for curricular content, clinical teaching, and availability of supports in medical school. By repositioning students' experiences with disability as sources of expertise, this study highlights opportunities for teaching compassionate care.

2016-01-01

The multifoci perspective of justice proposes that individuals tend to target their (in)justice reactions toward the perceived source of the mistreatment. Empirical support for target-specific reactions, however, has been mixed. To explore theoretically relevant reasons for these discrepant results and address unanswered questions in the multifoci justice literature, the present research examines how different justice sources might interactively predict target-specific reactions, and whether these effects occur as a function of moral identity. Results from a sample of North American frontline service employees (N = 314, Study 1) showed that among employees with lower levels of moral identity, low supervisor justice exacerbated the association between low customer justice and customer-directed sabotage, whereas this exacerbation effect was not observed among employees with higher levels of moral identity. This 3-way interaction effect was replicated in a sample of South Korean employees (N = 265, Study 2). (c) 2016 APA, all rights reserved).

High-speed imaging of vocal fold vibrations and larynx movements within vocalizations of different vowels.

Theoretic investigations of the "source-filter" model have indicated a pronounced acoustic interaction of glottal source and vocal tract. Empirical investigations of formant pattern variations apart from changes in vowel identity have demonstrated a direct relationship between the fundamental frequency and the patterns. As a consequence of both findings, independence of phonation and articulation may be limited in the speech process. Within the present study, possible interdependence of phonation and phoneme was investigated: vocal fold vibrations and larynx position for vocalizations of different vowels in a healthy man and woman were examined by high-speed light-intensified digital imaging. We found 1) different movements of the vocal folds for vocalizations of different vowel identities within one speaker and at similar fundamental frequency, and 2) constant larynx position within vocalization of one vowel identity, but different positions for vocalizations of different vowel identities. A possible relationship between the vocal fold vibrations and the phoneme is discussed.

Bacterial Communities in Boreal Forest Mushrooms Are Shaped Both by Soil Parameters and Host Identity

2017-01-01

Despite recent advances in understanding the microbiome of eukaryotes, little is known about microbial communities in fungi. Here we investigate the structure of bacterial communities in mushrooms, including common edible ones, with respect to biotic and abiotic factors in the boreal forest. Using a combination of culture-based and Illumina high-throughput sequencing, we characterized the bacterial communities in fruitbodies of fungi from eight genera spanning four orders of the class Agaricomycetes (Basidiomycota). Our results revealed that soil pH followed by fungal identity are the main determinants of the structure of bacterial communities in mushrooms. While almost half of fruitbody bacteria were also detected from soil, the abundance of several bacterial taxa differed considerably between the two environments. The effect of host identity was significant at the fungal genus and order level and could to some extent be ascribed to the distinct bacterial community of the chanterelle, representing Cantharellales—the earliest diverged group of mushroom-forming basidiomycetes. These data suggest that besides the substantial contribution of soil as a major taxa source of bacterial communities in mushrooms, the structure of these communities is also affected by the identity of the host. Thus, bacteria inhabiting fungal fruitbodies may be non-randomly selected from environment based on their symbiotic functions and/or habitat requirements. PMID:28539921

Hand Grasping Synergies As Biometrics.

2017-01-01

Recently, the need for more secure identity verification systems has driven researchers to explore other sources of biometrics. This includes iris patterns, palm print, hand geometry, facial recognition, and movement patterns (hand motion, gait, and eye movements). Identity verification systems may benefit from the complexity of human movement that integrates multiple levels of control (neural, muscular, and kinematic). Using principal component analysis, we extracted spatiotemporal hand synergies (movement synergies) from an object grasping dataset to explore their use as a potential biometric. These movement synergies are in the form of joint angular velocity profiles of 10 joints. We explored the effect of joint type, digit, number of objects, and grasp type. In its best configuration, movement synergies achieved an equal error rate of 8.19%. While movement synergies can be integrated into an identity verification system with motion capture ability, we also explored a camera-ready version of hand synergies-postural synergies. In this proof of concept system, postural synergies performed well, but only when specific postures were chosen. Based on these results, hand synergies show promise as a potential biometric that can be combined with other hand-based biometrics for improved security.

Stochastic recruitment leads to symmetry breaking in foraging populations

2014-03-01

When an ant colony is faced with two identical equidistant food sources, the foraging ants are found to concentrate more on one source than the other. Analogous symmetry-breaking behaviours have been reported in various population systems, (such as queueing or stock market trading) suggesting the existence of a simple universal mechanism. Past studies have neglected the effect of demographic noise and required rather complicated models to qualitatively reproduce this behaviour. I will show how including the effects of demographic noise leads to a radically different conclusion. The symmetry-breaking arises solely due to the process of recruitment and ceases to occur for large population sizes. The latter fact provides a testable prediction for a real system.

Adolescent Girls' STEM Identity Formation and Media Images of STEM Professionals: Considering the Influence of Contextual Cues.

Popular media have played a crucial role in the construction, representation, reproduction, and transmission of stereotypes of science, technology, engineering, and mathematics (STEM) professionals, yet little is known about how these stereotypes influence STEM identity formation. Media images of STEM professionals may be important sources of information about STEM and may be particularly salient and relevant for girls during adolescence as they actively consider future personal and professional identities. This article describes gender-stereotyped media images of STEM professionals and examines theories to identify variables that explain the potential influence of these images on STEM identity formation. Understanding these variables is important for expanding current conceptual frameworks of science/STEM identity to better determine how and when cues in the broader sociocultural context may affect adolescent girls' STEM identity. This article emphasizes the importance of focusing on STEM identity relevant variables and STEM identity status to explain individual differences in STEM identity formation.

The Quebec primary health care delivery system has experienced numerous reforms over the last 15 years. In this study, we sought to examine how managers and primary care providers made sense of the creation of successive new primary care organizational forms. We conducted a longitudinal qualitative case study in a primary care practice group located in Montreal, Quebec, for over 6 years (2002 to 2008). The data sources for the study include 31 semi-structured interviews with key informants, in-situ observations of group meetings, as well as documents and field notes. Textual material was submitted to narrative and metaphor analysis. The core metaphor of the journey came from a set of stories in which the members of this primary care group depicted the processes undertaken towards developing a multidisciplinary cooperative practice, which include an uneasy departure, uncertainty about the destination, conflict among members who jump ship or stay on board, negotiations about the itinerary, and, finally, enduring challenges in leading the way and being pioneers of change in the organization of primary care in their institutional context. Identification with the initial family medicine unit identity was persistent over time, but successive reforms further enriched its meaning as it became a multidisciplinary primary care practice pioneering organizational change. In order to support primary care reforms in complex institutional fields, this study proposes that decision-makers undertake a journey in which they recognize both the need to capitalize on existing meaningful and legitimated organizational identities, as well as the necessity for collective leadership in the management of multiple organizational identities over time.

Decades of communication research have shown that the stories we humans tell ourselves about ourselves reflect and shape our identities as members of our particular culture(s). By creating texts that portray a group rarely made visible, lesbian comic artists both represent and define lesbian identity and community. This textual analysis of the work of four comic artists, Alison Bechdel, Diane DiMassa, Justine Shaw, and Ariel Schrag, demonstrates how lesbian comic book artists draw on and contribute to the notions of lesbian identity and community. This study of the comics and secondary sources reveals three interconnected themes: visibility, self-reflexivity, and the complex interrelation of and process of defining identity and community.

The purpose of this article is to educate nurse practitioners (NPs) regarding: (a) the definition and range of transgenderism, (b) social influences on transgender persons, and (c) health care for transgender persons. Data sources include review of the literature in the areas of gender, gender identity, marginalized populations, and gender transition. Personal communication was also utilized. Transgender persons remain marginalized and may remain closeted and at risk for negative psychosocial consequences. For those that do come out, other issues present, including the navigation of gender transition and psychosocial and physical changes that may be positive and/or negative. Examples of positive effects may include satisfaction of living authentically and decrease in depression. Negative effects may include social discrimination and loss of relationships. To provide holistic care, NPs need to be aware of transgender lives in social context and of their healthcare needs. Suggestions for cultivating a supportive healthcare environment include the usage of sensitive language and an appropriate health history and physical examination. Further, to help rectify the knowledge deficit regarding transgender care among healthcare providers, NP educators and preceptors may utilize this article as a resource in their work with students. ©2011 The Author(s) Journal compilation ©2011 American Academy of Nurse Practitioners.

We construct bilinear identities for wave functions of an extended B-type Kadomtsev-Petviashvili (BKP) hierarchy containing two types of (2+1)-dimensional Sawada-Kotera equations with a self-consistent source. Introducing an auxiliary variable corresponding to the extended flow for the BKP hierarchy, we find the τ -function and bilinear identities for this extended BKP hierarchy. The bilinear identities generate all the Hirota bilinear equations for the zero-curvature forms of this extended BKP hierarchy. As examples, we obtain the Hirota bilinear equations for the two types of (2+1)-dimensional Sawada-Kotera equations in explicit form.

The current investigation examined the influence of the media on gay, lesbian, and bisexual (GLB) identity using both survey and in-depth interview approaches. In Study 1, 126 GLB survey respondents (11 unreported) in Texas indicated that the media influenced their self-realization, coming out, and current identities by providing role models and inspiration. In Study 2, 15 interviewees (6 women and 9 men) revealed that media role models serve as sources of pride, inspiration, and comfort. Our findings suggest that increasing the availability of GLB role models in the media may positively influence GLB identity.

CILogon: An Integrated Identity and Access Management Platform for Science

NASA Astrophysics Data System (ADS)

Basney, J.

2016-12-01

When scientists work together, they use web sites and other software to share their ideas and data. To ensure the integrity of their work, these systems require the scientists to log in and verify that they are part of the team working on a particular science problem. Too often, the identity and access verification process is a stumbling block for the scientists. Scientific research projects are forced to invest time and effort into developing and supporting Identity and Access Management (IAM) services, distracting them from the core goals of their research collaboration. CILogon provides an IAM platform that enables scientists to work together to meet their IAM needs more effectively so they can allocate more time and effort to their core mission of scientific research. The CILogon platform enables federated identity management and collaborative organization management. Federated identity management enables researchers to use their home organization identities to access cyberinfrastructure, rather than requiring yet another username and password to log on. Collaborative organization management enables research projects to define user groups for authorization to collaboration platforms (e.g., wikis, mailing lists, and domain applications). CILogon's IAM platform serves the unique needs of research collaborations, namely the need to dynamically form collaboration groups across organizations and countries, sharing access to data, instruments, compute clusters, and other resources to enable scientific discovery. CILogon provides a software-as-a-service platform to ease integration with cyberinfrastructure, while making all software components publicly available under open source licenses to enable re-use. Figure 1 illustrates the components and interfaces of this platform. CILogon has been operational since 2010 and has been used by over 7,000 researchers from more than 170 identity providers to access cyberinfrastructure including Globus, LIGO, Open Science Grid, SeedMe, and XSEDE. The "CILogon 2.0" platform, launched in 2016, adds support for virtual organization (VO) membership management, identity linking, international collaborations, and standard integration protocols, through integration with the Internet2 COmanage collaboration software.

   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.

11. '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.

Common source-multiple load vs. separate source-individual load photovoltaic system

NASA Technical Reports Server (NTRS)

Appelbaum, Joseph

1989-01-01

A comparison of system performance is made for two possible system setups: (1) individual loads powered by separate solar cell sources; and (2) multiple loads powered by a common solar cell source. A proof for resistive loads is given that shows the advantage of a common source over a separate source photovoltaic system for a large range of loads. For identical loads, both systems perform the same.

Adult age differences in unconscious transference: source confusion or identity blending?

PubMed

Perfect, Timothy J; Harris, Lucy J

2003-06-01

Eyewitnesses are known often to falsely identify a familiar but innocent bystander when asked to pick out a perpetrator from a lineup. Such unconscious transference errors have been attributed to either identity confusions at encoding or source retrieval errors. Three experiments contrasted younger and older adults in their susceptibility to such misidentifications. Participants saw photographs of perpetrators, then a series of mug shots of innocent bystanders. A week later, they saw lineups containing bystanders (and others containing perpetrators in Experiment 3) and were asked whether any of the perpetrators were present. When younger faces were used as stimuli (Experiments 1 and 3), older adults showed higher rates of transference errors. When older faces were used as stimuli (Experiments 2 and 3), no such age effects in rates of unconscious transference were apparent. In addition, older adults in Experiment 3 showed an own-age bias effect for correct identification of targets. Unconscious transference errors were found to be due to both source retrieval errors and identity confusions, but age-related increases were found only in the latter.

Operational Definitions of Sexual Orientation and Estimates of Adolescent Health Risk Behaviors

PubMed Central

Matthews, Derrick D.; Blosnich, John R.; Farmer, Grant W.; Adams, Brian J.

2014-01-01

Purpose Increasing attention to the health of lesbian, gay, and bisexual (LGB) populations comes with requisite circumspection about measuring sexual orientation in surveys. However, operationalizing these variables also requires considerable thought. This research sought to document the consequences of different operational definitions of sexual orientation by examining variation in health risk behaviors. Methods Using Massachusetts Youth Risk Behavior Survey data, we examined how operational definitions of sexual behavior and sexual identity influenced differences among three health behaviors known to disparately affect LGB populations: smoking, suicide risk, and methamphetamine use. Sexual behavior and sexual identity were also examined together to explore if they captured unique sources of variability in behavior. Results Estimates of health disparities changed as a result of using either sexual behavior or sexual identity. Youth who reported their sexual identity as “not sure” also had increased odds of health risk behavior. Disaggregating bisexual identity and behavior from same-sex identity and behavior frequently resulted in the attenuation or elimination of health disparities that would have otherwise been attributable to exclusively same-sex sexual minorities. Finally, sexual behavior and sexual identity explained unique and significant sources of variability in all three health behaviors. Conclusion Researchers using different operational definitions of sexual orientation could draw different conclusions, even when analyzing the same data, depending upon how they chose to represent sexual orientation in analyses. We discuss implications that these manipulations have on data interpretation and provide specific recommendations for best-practices when analyzing sexual orientation data collected from adolescent populations.

Fuzzy Similarity and Fuzzy Inclusion Measures in Polyline Matching: A Case Study of Potential Streams Identification for Archaeological Modelling in GIS

Ďuračiová, Renata; Rášová, Alexandra; Lieskovský, Tibor

2017-12-01

When combining spatial data from various sources, it is often important to determine similarity or identity of spatial objects. Besides the differences in geometry, representations of spatial objects are inevitably more or less uncertain. Fuzzy set theory can be used to address both modelling of the spatial objects uncertainty and determining the identity, similarity, and inclusion of two sets as fuzzy identity, fuzzy similarity, and fuzzy inclusion. In this paper, we propose to use fuzzy measures to determine the similarity or identity of two uncertain spatial object representations in geographic information systems. Labelling the spatial objects by the degree of their similarity or inclusion measure makes the process of their identification more efficient. It reduces the need for a manual control. This leads to a more simple process of spatial datasets update from external data sources. We use this approach to get an accurate and correct representation of historical streams, which is derived from contemporary digital elevation model, i.e. we identify the segments that are similar to the streams depicted on historical maps.

The Impact of an Authentic Science Experience on STEM Identity: A Preliminary Analysis of YouthAstroNet and MicroObservatory Telescope Network Participant Data

NASA Astrophysics Data System (ADS)

Dussault, Mary E.; Wright, Erika A.; Sadler, Philip; Sonnert, Gerhard; ITEAMS II Team

2018-01-01

Encouraging students to pursue careers in science, technology, engineering, and mathematics (STEM) is a high priority for national K-12 education improvement initiatives in the United States. Many educators have claimed that a promising strategy for nurturing early student interest in STEM is to engage them in authentic inquiry experiences. “Authentic” refers to investigations in which the questions are of genuine interest and importance to students, and the inquiry more closely resembles the way real science is done. Science education researchers and practitioners at the Harvard-Smithsonian Center for Astrophysics have put this theory into action with the development of YouthAstroNet, a nationwide online learning community of middle-school aged students, educators, and STEM professionals that features the MicroObservatory Robotic Telescope Network, professional image analysis software, and complementary curricula for use in a variety of learning settings. This preliminary study examines factors that influence YouthAstroNet participants' Science Affinity, STEM Identity, and STEM Career Interest, using the matched pre/post survey results of 261 participants as the data source. The pre/post surveys included some 40 items measuring affinity, identity, knowledge, and career interest. In addition, the post intervention instrument included a number of items in which students reported the instructional strategies they experienced as part of the program. A simple analysis of pre-post changes in affinity and interest revealed very little significant change, and for those items where a small pre-post effect was observed, the average change was most often negative. However, after accounting for students' different program treatment experiences and for their prior attitudes and interests, a predictor of significant student gains in Affinity, STEM Identity, Computer/Math Identity, and STEM Career Interest could be identified. This was the degree to which students reported using and experiencing the primary "authentic" learning activities of the YouthAstroNet program.

"I'm Not a Spiritual Person." How Hope Might Facilitate Conversations About Spirituality Among Teens and Young Adults With Cancer.

2018-06-01

Supporting patients' spiritual needs is central to palliative care. Adolescents and young adults (AYAs) may be developing their spiritual identities; it is unclear how to navigate conversations concerning their spiritual needs. To 1) describe spiritual narratives among AYAs based on their self-identification as religious, spiritual, both, or neither and 2) identify language to support AYAs' spiritual needs in keeping with their self-identities. In this mixed-methods, prospective, longitudinal cohort study, AYAs (14-25 years old) with newly diagnosed cancer self-reported their "religiousness" and "spirituality." One-on-one, semistructured interviews were conducted at three time points (within 60 days of diagnosis, six to 12 months, and 12-18 months later) and included queries about spirituality, God/prayer, meaning from illness, and evolving self-identity. Post hoc directed content analysis informed a framework for approaching religious/spiritual discussions. Seventeen AYAs (mean age 17.1 years, SD = 2.7, 47% male) participated in 44 interviews. Of n = 16 with concurrent survey responses, five (31%) self-identified as both "religious and spiritual," five (31%) as "spiritual, not religious," one (6%) as "religious, not spiritual," and five (31%) as neither. Those who endorsed religiousness tended to cite faith as a source of strength, whereas many who declined this self-identity explicitly questioned their preexisting beliefs. Regardless of self-identified "religiousness" or "spirituality," most participants endorsed quests for meaning, purpose, and/or legacy, and all included constructs of hope in their narratives. AYA self-identities evolve during the illness experience. When words such as "religion" and "spirituality" do not fit, explicitly exploring hopes, worries, meaning, and changing life perspectives may be a promising alternative.

Identification of fecal input sites in spring water by selection and genotyping of multiresistant Escherichia coli.

Wicki, Melanie; Karabulut, Fatma; Auckenthaler, Adrian; Felleisen, Richard; Tanner, Marcel; Baumgartner, Andreas

2011-12-01

The localization of fecal input sites is important for water quality management. For this purpose, we have developed a new approach based on a three-step procedure, including a preparatory phase, the screening of multiresistant bacteria using selective agar plates, and a typing phase where selected Escherichia coli isolates are characterized by antibiotic resistance profiles and molecular fingerprinting techniques (pulsed-field gel electrophoresis [PFGE]). These two well-known source tracking methods were combined in order to reduce cost and effort. This approach was successfully applied under field conditions in a study area located in the north-western part of Switzerland. E. coli isolates from spring water and surface water samples collected in this area were screened with selective agar plates. In this way, 21 different groups, each consisting of strains with the same pattern of antibiotic resistance, were found. Of these, four groups were further analyzed using PFGE. Strains with identical PFGE profiles were detected repeatedly, demonstrating the suitability of this method for the localization of fecal input sites over an extended period of time. Identical PFGE patterns of strains detected in water from two different springs were also found in the stream flowing through the study area. These results demonstrated the applicability of the new approach for the examination of incidents of fecal contamination in drinking water. The advantages of the described approach over genotyping methods currently being used to identify sources of fecal contaminants are a reduction in time, costs, and the effort required. Identical isolates could be identified without the construction of large libraries.

To investigate whether human breast milk contains potentially probiotic lactic acid bacteria, and therefore, whether it can be considered a synbiotic food. Study design Lactic acid bacteria were isolated from milk, mammary areola, and breast skin of eight healthy mothers and oral swabs and feces of their respective breast-fed infants. Some isolates (178 from each mother and newborn pair) were randomly selected and submitted to randomly amplified polymorphic DNA (RAPD) polymerase chain reaction analysis, and those that displayed identical RAPD patterns were identified by 16S rDNA sequencing. Within each mother and newborn pair, some rod-shaped lactic acid bacteria isolated from mammary areola, breast milk, and infant oral swabs and feces displayed identical RAPD profiles. All of them, independently from the mother and child pair, were identified as Lactobacillus gasseri. Similarly, among coccoid lactic acid bacteria from these different sources, some shared an identical RAPD pattern and were identified as Enterococcus faecium. In contrast, none of the lactic acid bacteria isolated from breast skin shared RAPD profiles with lactic acid bacteria of the other sources. Breast-feeding can be a significant source of lactic acid bacteria to the infant gut. Lactic acid bacteria present in milk may have an endogenous origin and may not be the result of contamination from the surrounding breast skin.

Patient identity management for secondary use of biomedical research data in a distributed computing environment.

Nitzlnader, Michael; Schreier, Günter

2014-01-01

Dealing with data from different source domains is of increasing importance in today's large scale biomedical research endeavours. Within the European Network for Cancer research in Children and Adolescents (ENCCA) a solution to share such data for secondary use will be established. In this paper the solution arising from the aims of the ENCCA project and regulatory requirements concerning data protection and privacy is presented. Since the details of secondary biomedical dataset utilisation are often not known in advance, data protection regulations are met with an identity management concept that facilitates context-specific pseudonymisation and a way of data aggregation using a hidden reference table later on. Phonetic hashing is proposed to prevent duplicated patient registration and re-identification of patients is possible via a trusted third party only. Finally, the solution architecture allows for implementation in a distributed computing environment, including cloud-based elements.

Self-esteem, ethnic identity, and behavioral adjustment among Anglo and Chicano adolescents in West Texas.

PubMed

Grossman, B; Wirt, R; Davids, A

1985-03-01

This study provides a comparison of similarities and differences with respect to ethnic identity between Anglo and Chicano adolescents from Texas. A path analysis model was used to test a theoretical assumption concerning proposed antecedents and consequences of self-esteem. Research instruments included the Rosenberg Self Esteem Scale, the Semantic Differential (scales for Myself and My Ethnic Group) and the McGuire White Measure of Social Status. Results were consistent with the interpretation that there is a relationship between being Chicano and having lower self-esteem, lower behavioral adjustment, and higher ethnic esteem. The prediction that ethnic esteem would mediate between ethnic group and self-esteem was upheld. Variables such as ethnic group membership per se and sex appear as or more important to the prediction of behavioral level. Clinical implications include recognizing that Chicanos low in self-esteem or behavioral adjustment should not automatically be considered unusual. The problems faced by this group are considered as having something in common with other groups of people who have more problems, lesser status, fewer resources, and fewer sources of available help.

Hydrophobic Organic Compounds in Hydraulic Fracturing Flowback Waters: Identification and Source Apportionment

Current hydraulic fracturing technologies rely on organic chemicals to serve multiple critical functions, including corrosion inhibition, in situ gel formation, and friction reduction. While industrial users have disclosed several hundreds of compound and mixture identities, it is unclear which of these are used and where, in what proportion, and with what frequency. Furthermore, while flowback and production waters contain both fracturing additive and geogenic compounds, they may contain potential reaction byproducts as well. Here, we identified several hundred organic compounds present in six hydraulic fracturing flowback waters over the Fayetteville shale. Identifications were made via non-target analysis using two-dimensional gas chromatography with time of flight mass spectrometry for hydrophobic organic compounds and liquid chromatography- orbitrap mass spectrometry. Compound identities were confirmed using purchased standards when available. Using the SkyTruth database and the Waxman list of disclosed compounds, we assigned compounds as either fracturing-fluid-derived or geogenic (or both), or a putative transformation products thereof. Several unreported halogenated compounds were detected, including chlorinated, brominated, and iodated species that have no known natural sources. Control studies indicated that these could not be formed under typical laboratory or field storage conditions, suggesting that halogenation reactions may give rise to novel compounds in the subsurface, presumably via reaction between fracturing fluid additives and shale-derived brines. Further, the six samples were strikingly heterogeneous, reflecting the diversity in fracturing fluid composition and flowback handling procedures at the time of the study.

What Experiences in Medical School Trigger Professional Identity Development?

PubMed

Kay, Denise; Berry, Andrea; Coles, Nicholas A

2018-04-02

Phenomenon: This qualitative inquiry used conceptual change theory as a theoretical lens to illuminate experiences in medical school that trigger professional identity formation. According to conceptual change theory, changes in personal conceptualizations are initiated when cognitive disequilibrium is introduced. We sought to identify the experiences that trigger cognitive disequilibrium and to subsequently describe students' perceptions of self-in-profession prior to the experience; the nature of the experience; and, when applicable, the outcomes of the experience. This article summarizes findings from portions of data collected in a larger qualitative study conducted at a new medical school in the United States that utilizes diverse pedagogies and experiences to develop student knowledge, clinical skills, attitudes, and dispositions. Primary data sources included focus groups and individual interviews with students across the 4 years of the curriculum (audio data). Secondary data included students' comments from course and end-of-year evaluations for the 2013-2017 classes (text data). Data treatment tools available in robust qualitative software, NVivo 10, were utilized to expedite coding of both audio and text data. Content analysis was adopted as the analysis method for both audio and text data. We identified four experiences that triggered cognitive disequilibrium in relationship to students' perceptions of self-in-profession: (a) transition from undergraduate student to medical student, (b) clinical experiences in the preclinical years, (c) exposure to the business of medicine, and (d) exposure to physicians in clinical practice. Insights: We believe these experiences represent vulnerable periods of professional identity formation during medical school. Educators interested in purposefully shaping curriculum to encourage adaptive professional identity development during medical school may find it useful to integrate educational interventions that assist students with navigating the disequilibrium that is introduced during these periods.

Stories and metaphors in the sensemaking of multiple primary health care organizational identities

PubMed Central

2014-01-01

Background The Quebec primary health care delivery system has experienced numerous reforms over the last 15 years. In this study, we sought to examine how managers and primary care providers made sense of the creation of successive new primary care organizational forms. Methods We conducted a longitudinal qualitative case study in a primary care practice group located in Montreal, Quebec, for over 6 years (2002 to 2008). The data sources for the study include 31 semi-structured interviews with key informants, in-situ observations of group meetings, as well as documents and field notes. Textual material was submitted to narrative and metaphor analysis. Results The core metaphor of the journey came from a set of stories in which the members of this primary care group depicted the processes undertaken towards developing a multidisciplinary cooperative practice, which include an uneasy departure, uncertainty about the destination, conflict among members who jump ship or stay on board, negotiations about the itinerary, and, finally, enduring challenges in leading the way and being pioneers of change in the organization of primary care in their institutional context. Identification with the initial family medicine unit identity was persistent over time, but successive reforms further enriched its meaning as it became a multidisciplinary primary care practice pioneering organizational change. Conclusions In order to support primary care reforms in complex institutional fields, this study proposes that decision-makers undertake a journey in which they recognize both the need to capitalize on existing meaningful and legitimated organizational identities, as well as the necessity for collective leadership in the management of multiple organizational identities over time.

Comparative Sensitivities of Gravitational Wave Detectors Based on Atom Interferometers and Light Interferometers

NASA Technical Reports Server (NTRS)

Baker, John G.; Thorpe, J. I.

2012-01-01

We consider a class of proposed gravitational wave detectors based on multiple atomic interferometers separated by large baselines and referenced by common laser systems. We compute the sensitivity limits of these detectors due to intrinsic phase noise of the light sources, non-inertial motion of the light sources, and atomic shot noise and compare them to sensitivity limits for traditional light interferometers. We find that atom interferometers and light interferometers are limited in a nearly identical way by intrinsic phase noise and that both require similar mitigation strategies (e.g. multiple arm instruments) to reach interesting sensitivities. The sensitivity limit from motion of the light sources is slightly different and favors the atom interferometers in the low-frequency limit, although the limit in both cases is severe. Whether this potential advantage outweighs the additional complexity associated with including atom interferometers will require further study.

Racial-ethnic Identity in Context: Examining Mediation of Neighborhood Factors on Children's Academic Adjustment.

Witherspoon, Dawn P; Daniels, Lisa L; Mason, Amber E; Smith, Emilie Phillips

2016-03-01

Research consistently shows that neighborhood socio-demographic characteristics and residents' neighborhood perceptions matter for youth well-being, including a positive sense of racial-ethnic identity. Although elementary-school children are likely in the earlier phases of identity formation, the authors examined whether objective and subjective neighborhood characteristics are related to their racial-ethnic identity and, in turn, their academic adjustment. A diverse sample (30.4% African American, 35.2% White, 12.3% Latino, & 22.0% Other) of 227 children in Grades 2 through 5 were surveyed in afterschool programs. Bivariate correlations showed that youth living in disadvantaged neighborhoods reported more barriers due to their race-ethnicity, but these barriers were not related to their sense of academic efficacy. Residing in a disadvantaged neighborhood was unrelated to youth's academic self-efficacy. However, path analyses showed that positive neighborhood perceptions were associated with a stronger sense of race-ethnicity (i.e., affirmation and belonging), which was in turn related to greater academic efficacy. These results suggest that neighborhood connection provides a source of affirmation and value for young children, helping them to understand who they are as part of a racial-ethnic group and helping to foster a sense of future achievement opportunities. This study provides additional evidence that along with other important proximal contexts (e.g., family, school), young children's neighborhood context is important for development. Results are discussed to highlight environmental influences on young children's awareness of race-ethnicity and the implications of the combined impact of neighborhood and racial-ethnic identity on psychosocial adjustment. © Society for Community Research and Action 2016.

FragIdent--automatic identification and characterisation of cDNA-fragments.

PubMed

Seelow, Dominik; Goehler, Heike; Hoffmann, Katrin

2009-03-02

Many genetic studies and functional assays are based on cDNA fragments. After the generation of cDNA fragments from an mRNA sample, their content is at first unknown and must be assigned by sequencing reactions or hybridisation experiments. Even in characterised libraries, a considerable number of clones are wrongly annotated. Furthermore, mix-ups can happen in the laboratory. It is therefore essential to the relevance of experimental results to confirm or determine the identity of the employed cDNA fragments. However, the manual approach for the characterisation of these fragments using BLAST web interfaces is not suited for larger number of sequences and so far, no user-friendly software is publicly available. Here we present the development of FragIdent, an application for the automatic identification of open reading frames (ORFs) within cDNA-fragments. The software performs BLAST analyses to identify the genes represented by the sequences and suggests primers to complete the sequencing of the whole insert. Gene-specific information as well as the protein domains encoded by the cDNA fragment are retrieved from Internet-based databases and included in the output. The application features an intuitive graphical interface and is designed for researchers without any bioinformatics skills. It is suited for projects comprising up to several hundred different clones. We used FragIdent to identify 84 cDNA clones from a yeast two-hybrid experiment. Furthermore, we identified 131 protein domains within our analysed clones. The source code is freely available from our homepage at http://compbio.charite.de/genetik/FragIdent/.

However, path analyses showed that positive neighborhood perceptions were associated with a stronger sense of race-ethnicity (i.e., affirmation and belonging), which was in turn related to greater academic efficacy. These results suggest that neighborhood connection provides a source of affirmation and value for young children, helping them to understand who they are as part of a racial-ethnic group and helping to foster a sense of future achievement opportunities. This study provides additional evidence that along with other important proximal contexts (e.g., family, school), young children’s neighborhood context is important for development. Results are discussed to highlight environmental influences on young children’s awareness of race-ethnicity and the implications of the combined impact of neighborhood and racial-ethnic identity on psychosocial adjustment.

Nordic-Baltic cooperation in adult education: A collective story of Estonian adult educators

NASA Astrophysics Data System (ADS)

Jõgi, Larissa; Karu, Katrin

2017-03-01

Adult Education has many values, including experiences and co-operation among people, and the fact that adult education is full of stories from adult educators, which can help to understand trends in the past and developments in the present. Established in 1991 as part of a more general regional cooperation among five Nordic and three Baltic countries (NB8), Nordic-Baltic cooperation in adult education has been mutually enriching and has resulted in the growth of a professional network. The cooperation has led participants through a time of new sources of values, knowledge and contacts, socialisation and transformation, inspiration and challenges, which has influenced their experiences and professional identities. This paper is based on the results of a study entitled "Nordic-Baltic cooperation in adult education: Experience and stories" and focuses on the experiences and professional identities of two generations of Estonian adult educators. The empirical data for the study were collected using narrative-biographical interviews. The paper discusses two research questions: (1) What is the perception and influence of experiences for adult educators? and (2) How have their experiences influenced the professional identity of adult educators?

Recently, the need for more secure identity verification systems has driven researchers to explore other sources of biometrics. This includes iris patterns, palm print, hand geometry, facial recognition, and movement patterns (hand motion, gait, and eye movements). Identity verification systems may benefit from the complexity of human movement that integrates multiple levels of control (neural, muscular, and kinematic). Using principal component analysis, we extracted spatiotemporal hand synergies (movement synergies) from an object grasping dataset to explore their use as a potential biometric. These movement synergies are in the form of joint angular velocity profiles of 10 joints. We explored the effect of joint type, digit, number of objects, and grasp type. In its best configuration, movement synergies achieved an equal error rate of 8.19%. While movement synergies can be integrated into an identity verification system with motion capture ability, we also explored a camera-ready version of hand synergies—postural synergies. In this proof of concept system, postural synergies performed well, but only when specific postures were chosen. Based on these results, hand synergies show promise as a potential biometric that can be combined with other hand-based biometrics for improved security. PMID:28512630

Spinal Health: The Backbone of Chiropractic's Identity.

PubMed

Brown, Richard A

2016-12-01

The purpose of this commentary is to explore the concepts underpinning professional identity, assess their relevance to chiropractic, and propose a model by which a strong identity for the chiropractic profession may be achieved. The professional identity of chiropractic has been a constant source of controversy throughout its history. Attempts to establish a professional identity have been met with resistance from internal factions divided over linguistics, philosophy, technique, and chiropractic's place in the health care framework. Consequently, the establishment of a clear identity has been challenging, and the chiropractic profession has failed to capitalize on its potential as the profession of spine care experts. Recent identity consultations have produced similar statements that position chiropractors as spinal health and well-being experts. Adoption of this identity, however, has not been universal, perpetuating the uncertainty with which the public regards the chiropractic profession. To gain public and professional acceptance, chiropractic must be unequivocal in declaring its scope, expertise, and intent. Failure to do so will lead to obscurity as other professions acquire necessary skills and position themselves as the custodians of spine care.

Single Neurons in the Avian Auditory Cortex Encode Individual Identity and Propagation Distance in Naturally Degraded Communication Calls.

Mouterde, Solveig C; Elie, Julie E; Mathevon, Nicolas; Theunissen, Frédéric E

2017-03-29

One of the most complex tasks performed by sensory systems is "scene analysis": the interpretation of complex signals as behaviorally relevant objects. The study of this problem, universal to species and sensory modalities, is particularly challenging in audition, where sounds from various sources and localizations, degraded by propagation through the environment, sum to form a single acoustical signal. Here we investigated in a songbird model, the zebra finch, the neural substrate for ranging and identifying a single source. We relied on ecologically and behaviorally relevant stimuli, contact calls, to investigate the neural discrimination of individual vocal signature as well as sound source distance when calls have been degraded through propagation in a natural environment. Performing electrophysiological recordings in anesthetized birds, we found neurons in the auditory forebrain that discriminate individual vocal signatures despite long-range degradation, as well as neurons discriminating propagation distance, with varying degrees of multiplexing between both information types. Moreover, the neural discrimination performance of individual identity was not affected by propagation-induced degradation beyond what was induced by the decreased intensity. For the first time, neurons with distance-invariant identity discrimination properties as well as distance-discriminant neurons are revealed in the avian auditory cortex. Because these neurons were recorded in animals that had prior experience neither with the vocalizers of the stimuli nor with long-range propagation of calls, we suggest that this neural population is part of a general-purpose system for vocalizer discrimination and ranging. SIGNIFICANCE STATEMENT Understanding how the brain makes sense of the multitude of stimuli that it continually receives in natural conditions is a challenge for scientists. Here we provide a new understanding of how the auditory system extracts behaviorally relevant information, the vocalizer identity and its distance to the listener, from acoustic signals that have been degraded by long-range propagation in natural conditions. We show, for the first time, that single neurons, in the auditory cortex of zebra finches, are capable of discriminating the individual identity and sound source distance in conspecific communication calls. The discrimination of identity in propagated calls relies on a neural coding that is robust to intensity changes, signals' quality, and decreases in the signal-to-noise ratio.

Brainstem origins for cortical 'what' and 'where' pathways in the auditory system.

PubMed

Kraus, Nina; Nicol, Trent

2005-04-01

We have developed a data-driven conceptual framework that links two areas of science: the source-filter model of acoustics and cortical sensory processing streams. The source-filter model describes the mechanics behind speech production: the identity of the speaker is carried largely in the vocal cord source and the message is shaped by the ever-changing filters of the vocal tract. Sensory processing streams, popularly called 'what' and 'where' pathways, are well established in the visual system as a neural scheme for separately carrying different facets of visual objects, namely their identity and their position/motion, to the cortex. A similar functional organization has been postulated in the auditory system. Both speaker identity and the spoken message, which are simultaneously conveyed in the acoustic structure of speech, can be disentangled into discrete brainstem response components. We argue that these two response classes are early manifestations of auditory 'what' and 'where' streams in the cortex. This brainstem link forges a new understanding of the relationship between the acoustics of speech and cortical processing streams, unites two hitherto separate areas in science, and provides a model for future investigations of auditory function.

Comparing sexual-minority and heterosexual young women's friends and parents as sources of support for sexual issues.

Friedman, Carly K; Morgan, Elizabeth M

2009-08-01

The present study provides a comparative analysis of sexual-minority and heterosexual emerging adult women's experiences seeking support for sexual issues from parents and friends. Participants included 229 college women (88 sexual-minority women; 141 heterosexual women), ranging from 18 to 25 years of age, who provided written responses to an inquiry about a time they went to friends and parents for support for a issue related to their sexuality. Responses indicated that the majority of participants had sought support from either a parent or a friend and that mothers and female friends were more likely involved than fathers or male friends, respectively. Sexual issues that participants reported discussing with parents and friends were inductively grouped into five categories: dating and romantic relationships, sexual behavior, sexual health, identity negotiation, and discrimination and violence. Issues that were discussed differed based on sexual orientation identity and the source of support (parent or friend); they did not differ by age. Participants generally perceived parents and friends' responses as helpful, though sexual-minority participants perceived both parents and friends' responses as less helpful than did heterosexual participants. Overall, results suggest both similarities and differences between sexual-minority and heterosexual young women's experiences seeking support for sexual issues from parents and friends.

Petrology of Hualalai volcano, Hawaii: Implication for mantle composition

USGS Publications Warehouse

Clague, D.A.; Jackson, E.D.; Wright, T.L.

1980-01-01

Hualalai is one of five volcanoes whose eruptions built the island of Hawaii. The historic 1800-1801 flows and the analyzed prehistoric flows exposed at the surface are alkalic basalts except for a trachyte cone and flow at Puu Waawaa and a trachyte maar deposit near Waha Pele. The 1800-1801 eruption produced two flows: the upper Kaupulehu flow and the lower Huehue flow. The analyzed lavas of the two 1800-1801 flows are geochemically identical with the exception of a few samples from the toe of the Huehue flow that appear to be derived from a separate magmatic batch. The analyzed prehistoric basalts are nearly identical to the 1800-1801 flows but include some lavas that have undergone considerable shallow crystal fractionation. The least fractionated alkalic basalts from Hualalai are in equilibrium with mantle olivine (Fo87) indicating that the Hawaiian mantle source region is not unusually iron-rich. The 1800-1801 and analyzed prehistoric basalts can be generated by about 5-10% partial fusion of a garnet-bearing source relatively enriched in the light-rare-earths. The mantle underlying the Hawaiian Islands is chemically and mineralogically heterogeneous before and after extraction of the magmas that make up the volcanoes. ?? 1980 Intern.

Negotiation of identity in group therapy for aphasia: the Aphasia Café.

PubMed

Simmons-Mackie, Nina; Elman, Roberta J

2011-01-01

There has been increasing interest in ensuring that aphasia intervention includes attention to the negotiation of a robust identity after the life-altering changes that often accompany the onset of aphasia. But how does one go about simultaneously improving communication and positive identity development within aphasia therapy? Socially oriented group therapy for aphasia has been touted as one means of addressing both psychosocial and communicative goals in aphasia. This article describes the results of a sociolinguistic analysis of group therapy for aphasia in which positive personal and group identity are skilfully negotiated. Sociolinguistic microanalysis of discourse in a group therapy session was undertaken. The session, described as group conversation therapy, included eight adults with aphasia, a speech-language pathologist and an assistant. The session was videotaped and transcribed, and the data were analysed to identify 'indices of identity' within the discourse. This included discourse that exposed members' roles, values or beliefs about themselves or others. The data were further analysed to identify 'patterns' of discourse associated with identity. The result is a detailed description of identity-enhancing discourse within group therapy for aphasia. The findings included several categories associated with the negotiation of identity in therapy including: (1) discourse demonstrating that group members were 'being heard', (2) that the competence of group members was assumed, (3) that 'solidarity' existed in the group, (4) that saving face and promoting positive personal identity was important, and (5) that markers of group identity were made visible via discourse that referenced both member inclusion as well as non-member exclusion. The results suggest that it is possible to create identity-enhancing interactions as part of therapy for aphasia; the analysis demonstrates the potential role of the group leader/clinician in managing identity negotiation in aphasia therapy. © 2010 Royal College of Speech & Language Therapists.

Understanding African American Adolescents’ Identity Development: A Relational Developmental Systems Perspective

PubMed Central

Brittian, Aerika S.

2012-01-01

This article examines the development of African American adolescents’ identity using a relational developmental systems theory framework, which led to the expectation that identity development is linked to both the reduction of risk behaviors and the promotion of African American adolescents’ healthy development. Different personological theories of identity development were discussed, including Erikson’s theory of psychosocial development and Marcia’s theory of identity statuses. Developmental systems theory was used to further the literature on African American adolescents’ identity development, by integrating various views of identity development as they pertain to these youth. Furthermore, the formation of many aspects of identity may be an important coping and resilience process for such youth. In addition, directions for future research are discussed, including a consideration of the complexity of diversity that exists within the African American adolescent population, and a call for more longitudinal assessments of identity development is presented.

Narratives of empowerment and compliance: studies of communication in online patient support groups.

PubMed

Wentzer, Helle S; Bygholm, Ann

2013-12-01

New technologies enable new forms of patient participation in health care. The article discusses whether communication in online patient support groups is a source of individual as well as collective empowerment or to be understood within the tradition of compliance. The discussion is based on a qualitative analysis of patient communication in two online groups on the Danish portal sundhed.dk, one for lung patients and one for women with fertility problems. The object of study is the total sum of postings during a specific period of time - a total of 4301 posts are included. The textmaterial was analyzed according to the textual paradigm of Paul Ricoeur, and the three steps of critical interpretation. Thus, the analysis moves from describing communicative characteristics of the site to a thorough semantic analysis of its narrative structure of construing meaning, interaction and collective identity, and finally as a source of collective action. The meta-narratives of the two groups confirm online patient support groups for individual empowerment, for collective group identity, but not for collective empowerment. The collective identities of patienthood on the two sites are created by the users (patients) through specific styles of communication and interaction, referred to as 'multi-logical narratives'. In spite of the potential of online communities of opening up health care to the critical voice of the public, the analysis points to a synthesis of the otherwise opposite positions of empowerment and compliance in patient care. On a collective level, the site is empowering the individual users to comply with 'doctor's recommendations' as a group. Copyright © 2013 Elsevier Ireland Ltd. All rights reserved.

Individual Quality Explains Variation in Reproductive Success Better than Territory Quality in a Long-Lived Territorial Raptor

PubMed Central

Zabala, Jabi; Zuberogoitia, Iñigo

2014-01-01

Evolution by natural selection depends on the relationship between individual traits and fitness. Variation in individual fitness can result from habitat (territory) quality and individual variation. Individual quality and specialization can have a deep impact on fitness, yet in most studies on territorial species the quality of territory and individuals are confused. We aimed to determine if variation in breeding success is better explained by territories, individual quality or a combination of both. We analysed the number of fledglings and the breeding quality index (the difference between the number of fledglings of an individual/breeding pair and the average number of fledglings of the monitored territories in the same year) as part of a long term (16 years) peregrine falcon (Falco peregrinus) monitoring program with identification of individuals. Using individual and territory identities as correlates of quality, we built Generalised Linear Models with Mixed effects, in which random factors depicted different hypotheses for sources of variation (territory/individual quality) in the reproductive success of unique breeding pairs, males and females, and assessed their performance. Most evidence supported the hypothesis that variation in breeding success is explained by individual identity, particularly male identity, rather than territory. There is also some evidence for inter year variations in the breeding success of females and a territory effect in the case of males. We argue that, in territorial species, individual quality is a major source of variation in breeding success, often masked by territory. Future ecological and conservation studies on habitat use should consider and include the effect of individuals, in order to avoid misleading results. PMID:24599280

2001-01-01

Eleven environmental samples from different sources were screened for the presence of metallo-β-lactamase-producing bacteria by using a selective enrichment medium containing a carbapenem antibiotic and subsequently testing each isolate for production of EDTA-inhibitable carbapenemase activity. A total of 15 metallo-β-lactamase-producing isolates, including 10 Stenotrophomonas maltophilia isolates, 3 Chryseobacterium spp., one Aeromonas hydrophila isolate, and one Janthinobacterium lividum isolate (a species in which production of metallo-β-lactamase activity was not previously reported), were obtained from 8 samples. In the J. lividum isolate, named JAC1, production of metallo-β-lactamase activity was elicited upon exposure to β-lactams. Screening of a JAC1 genomic library for clones showing a reduced imipenem susceptibility led to the isolation of a metallo-β-lactamase determinant encoding a new member (named THIN-B) of the highly divergent subclass B3 lineage of metallo-β-lactamases. THIN-B is most closely related (35.6% identical residues) to the L1 enzyme of S. maltophilia and more distantly related to the FEZ-1 enzyme of Legionella gormanii (27.8% identity) and to the GOB-1 enzyme of Chryseobacterium meningosepticum (24.2% identity). Sequences related to blaTHIN-B, and inducible production of metallo-β-lactamase activity, were also detected in the J. lividum type strain DSM1522. Expression of the blaTHIN-B gene in Escherichia coli resulted in decreased susceptibility to several β-lactams, including penicillins, cephalosporins (including cephamycins and oxyimino cephalosporins), and carbapenems, revealing a broad substrate specificity of the enzyme. The results of this study indicated that metallo-β-lactamase-producing bacteria are widespread in the environment and identified a new molecular class B enzyme in the environmental species J. lividum.

A series of tests was designed to evaluate the performance of the field and laboratory emission cell (FLEC) as applied to the testing of emissions from two indoor coating materials, floor wax and latex paint. These tests included validation of the repeatability of the test method, evaluation of the effect of different air velocities on source emissions, and a comparison of FLEC versus small chamber characterization of emissions. The FLEC exhibited good repeatability in characterization of emissions when applied to both sources under identical conditions. Tests with different air velocities showed significant effects on the emissions from latex paint, yetmore » little effect on emissions from the floor wax. Comparisons of data from the FLEC and small chamber show good correlation for measurements involving floor wax, but less favorable results for emissions from latex paint. The procedures and findings are discussed; conclusions are limited and include emphasis on the need for additional study and development of a standard method.« less

Social-historical study conducted to examine the contribution of the American Nurses of Project HOPE to the configuration of the professional identity of the first trained nurses in Alagoas, in the period of 1973-1977. The theoretical framework was the "Civilizing Process" of Norbert Elias. Primary sources were official documents and personal files of 13 respondents by oral history; the secondary sources were authors of the History of Brazil/Alagoas. Data analysis showed that the configuration of the professional identity of the first trained nurses in Alagoas was a civilizing process, with all the nuances that make up the power relations. There was a significant contribution of American Nursing. However the movement of resistance to this domination was very strong, resulting in a Course that could take advantage of technological advancement and prestige brought by the United States, to build a unique Nursing from the social fabric embroidery at this meeting with so many different cultures.

Wanting to See People Like Me? Racial and Gender Diversity in Popular Adolescent Television

Media are one source for adolescent identity development and social identity gratifications. Nielsen viewing data across the 2014–2015 television season for adolescents ages 14–17 was used to examine racial and gender diversity in adolescent television exposure. Compared to U.S. Census data, mainstream shows underrepresent women, but the proportion of Black characters is roughly representative. Black adolescents watch more television than non-Black adolescents and, after taking this into account, shows popular with Black adolescents are more likely than shows popular with non-Black adolescents to exhibit racial diversity. In addition, shows popular with female adolescents are more likely than shows popular with males to exhibit gender diversity. These results support the idea that adolescents seek out media messages with characters that are members of their identity groups, possibly because the characters serve as tools for identity development and social identity gratifications.

Integrating Data Sources for Process Sustainability ...

EPA Pesticide Factsheets

To perform a chemical process sustainability assessment requires significant data about chemicals, process design specifications, and operating conditions. The required information includes the identity of the chemicals used, the quantities of the chemicals within the context of the sustainability assessment, physical properties of these chemicals, equipment inventory, as well as health, environmental, and safety properties of the chemicals. Much of this data are currently available to the process engineer either from the process design in the chemical process simulation software or online through chemical property and environmental, health, and safety databases. Examples of these databases include the U.S. Environmental Protection Agency’s (USEPA’s) Aggregated Computational Toxicology Resource (ACToR), National Institute for Occupational Safety and Health’s (NIOSH’s) Hazardous Substance Database (HSDB), and National Institute of Standards and Technology’s (NIST’s) Chemistry Webbook. This presentation will provide methods and procedures for extracting chemical identity and flow information from process design tools (such as chemical process simulators) and chemical property information from the online databases. The presentation will also demonstrate acquisition and compilation of the data for use in the EPA’s GREENSCOPE process sustainability analysis tool. This presentation discusses acquisition of data for use in rapid LCI development.

An Efficient Variable Length Coding Scheme for an IID Source

NASA Technical Reports Server (NTRS)

Cheung, K. -M.

1995-01-01

A scheme is examined for using two alternating Huffman codes to encode a discrete independent and identically distributed source with a dominant symbol. This combined strategy, or alternating runlength Huffman (ARH) coding, was found to be more efficient than ordinary coding in certain circumstances.

On October 29, 2012, Hurricane Sandy made landfall and devastated New York's metropolitan area, causing widespread damage to homes and the utility infrastructure. Eight days later, snow and freezing temperatures from a nor'easter storm delayed utility restoration. To examine carbon monoxide (CO) exposures in the 2 weeks following Hurricane Sandy. Methods. This was a retrospective review of prospectively collected, standardized, and de-identified data sets. CO exposures and poisonings identified from two electronic surveillance systems, the New York City Poison Control Center (NYCPCC) and New York City's Syndromic Surveillance Unit, were compared with CO exposures from identical dates in 2008-2011. Data collected from the poison center included exposure type, CO source, poisoning type, treatment, and outcomes. Data collected from the Syndromic Surveillance Unit cases, which were identified by CO-related chief complaints presenting to NYC hospitals, included visit date and time, and patient demographics. Four hundred thirty-seven CO exposures were reported to the NYCPCC, 355 from NYC callers, and the remainder from surrounding counties, which represented a significant increase when compared with CO exposures from identical dates in the preceding 4 years (p < 0.001). The total cases that were reported to the NYCPCC in 2008, 2009, 2010, and 2011 were 18, 13, 24, and 61, respectively. Excluding a single apartment fire that occurred (n = 311), the more common sources of CO were grilling indoors (26.2%) and generators (17.5%). Syndromic surveillance captured 70 cases; 6 cases were captured by both data sets. CO exposures following weather-related disasters are a significant public health concern, and the use of fuel-burning equipment is a clear source of storm-related morbidity and mortality. Multiple real-time epidemiologic surveillance tools are useful in estimating the prevalence of CO exposure and poisoning and are necessary to assist public health efforts to prevent CO poisoning during and after disasters.

A two-metric proposal to specify the color-rendering properties of light sources for retail lighting

Freyssinier, Jean Paul; Rea, Mark

2010-08-01

Lighting plays an important role in supporting retail operations, from attracting customers, to enabling the evaluation of merchandise, to facilitating the completion of the sale. Lighting also contributes to the identity, comfort, and visual quality of a retail store. With the increasing availability and quality of white LEDs, retail lighting specifiers are now considering LED lighting in stores. The color rendering of light sources is a key factor in supporting retail lighting goals and thus influences a light source's acceptance by users and specifiers. However, there is limited information on what consumers' color preferences are, and metrics used to describe the color properties of light sources often are equivocal and fail to predict preference. The color rendering of light sources is described in the industry solely by the color rendering index (CRI), which is only indirectly related to human perception. CRI is intended to characterize the appearance of objects illuminated by the source and is increasingly being challenged because new sources are being developed with increasingly exotic spectral power distributions. This paper discusses how CRI might be augmented to better use it in support of the design objectives for retail merchandising. The proposed guidelines include the use of gamut area index as a complementary metric to CRI for assuring good color rendering.

Extending a Tandem Mass Spectral Library to Include MS2 Spectra of Fragment Ions Produced In-Source and MSn Spectra.

PubMed

Yang, Xiaoyu; Neta, Pedatsur; Stein, Stephen E

2017-11-01

Tandem mass spectral library searching is finding increased use as an effective means of determining chemical identity in mass spectrometry-based omics studies. We previously reported on constructing a tandem mass spectral library that includes spectra for multiple precursor ions for each analyte. Here we report our method for expanding this library to include MS 2 spectra of fragment ions generated during the ionization process (in-source fragment ions) as well as MS 3 and MS 4 spectra. These can assist the chemical identification process. A simple density-based clustering algorithm was used to cluster all significant precursor ions from MS 1 scans for an analyte acquired during an infusion experiment. The MS 2 spectra associated with these precursor ions were grouped into the same precursor clusters. Subsequently, a new top-down hierarchical divisive clustering algorithm was developed for clustering the spectra from fragmentation of ions in each precursor cluster, including the MS 2 spectra of the original precursors and of the in-source fragments as well as the MS n spectra. This algorithm starts with all the spectra of one precursor in one cluster and then separates them into sub-clusters of similar spectra based on the fragment patterns. Herein, we describe the algorithms and spectral evaluation methods for extending the library. The new library features were demonstrated by searching the high resolution spectra of E. coli extracts against the extended library, allowing identification of compounds and their in-source fragment ions in a manner that was not possible before.

(60)Co were detected in common octopus specimens collected in the East China Sea in 1996-2005. The source of (60)Co has remained unclear yet. Stable isotope analyses showed that there was no difference in stable Co concentrations between octopus samples with (60)Co and without (60)Co. This result showed that the stable Co in the digestive gland of octopus potentially did not include a trace amount of (60)Co and the source of (60)Co existed independently. Furthermore, investigations of octopus in other area and other species indicated that the origin of the source of (60)Co occurred locally in the restricted area in the East China Sea and not in the coastal area of Japan. Concentrations of (60)Co have annually decreased with shorter half-life than the physical half-life. This decrease tendency suggests that the sources of (60)Co were identical and were temporary dumped into the East China Sea as a solid waste. Copyright 2010 Elsevier Ltd. All rights reserved.

Modification of the Douglas Neumann program to improve the efficiency of predicting component interference and high lift characteristics

NASA Technical Reports Server (NTRS)

Bristow, D. R.; Grose, G. G.

1978-01-01

The Douglas Neumann method for low-speed potential flow on arbitrary three-dimensional lifting bodies was modified by substituting the combined source and doublet surface paneling based on Green's identity for the original source panels. Numerical studies show improved accuracy and stability for thin lifting surfaces, permitting reduced panel number for high-lift devices and supercritical airfoil sections. The accuracy of flow in concave corners is improved. A method of airfoil section design for a given pressure distribution, based on Green's identity, was demonstrated. The program uses panels on the body surface with constant source strength and parabolic distribution of doublet strength, and a doublet sheet on the wake. The program is written for the CDC CYBER 175 computer. Results of calculations are presented for isolated bodies, wings, wing-body combinations, and internal flow.

Modified Dempster-Shafer approach using an expected utility interval decision rule

Cheaito, Ali; Lecours, Michael; Bosse, Eloi

1999-03-01

The combination operation of the conventional Dempster- Shafer algorithm has a tendency to increase exponentially the number of propositions involved in bodies of evidence by creating new ones. The aim of this paper is to explore a 'modified Dempster-Shafer' approach of fusing identity declarations emanating form different sources which include a number of radars, IFF and ESM systems in order to limit the explosion of the number of propositions. We use a non-ad hoc decision rule based on the expected utility interval to select the most probable object in a comprehensive Platform Data Base containing all the possible identity values that a potential target may take. We study the effect of the redistribution of the confidence levels of the eliminated propositions which otherwise overload the real-time data fusion system; these eliminated confidence levels can in particular be assigned to ignorance, or uniformly added to the remaining propositions and to ignorance. A scenario has been selected to demonstrate the performance of our modified Dempster-Shafer method of evidential reasoning.

The language used by National Health Service (NHS) "commissioning" managers when discussing their roles and responsibilities can be seen as a manifestation of "identity work", defined as a process of identifying. This paper aims to offer a novel approach to analysing "identity work" by triangulation of multiple analytical methods, combining analysis of the content of text with analysis of its form. Fairclough's discourse analytic methodology is used as a framework. Following Fairclough, the authors use analytical methods associated with Halliday's systemic functional linguistics. While analysis of the content of interviews provides some information about NHS Commissioners' perceptions of their roles and responsibilities, analysis of the form of discourse that they use provides a more detailed and nuanced view. Overall, the authors found that commissioning managers have a higher level of certainty about what commissioning is not rather than what commissioning is; GP managers have a high level of certainty of their identity as a GP rather than as a manager; and both GP managers and non-GP managers oscillate between multiple identities depending on the different situations they are in. This paper offers a novel approach to triangulation, based not on the usual comparison of multiple data sources, but rather based on the application of multiple analytical methods to a single source of data. This paper also shows the latent uncertainty about the nature of commissioning enterprise in the English NHS.

This mixed methods study explored the characteristics of and experiences with perceived discrimination in an ethnically diverse urban sample of adults experiencing homelessness and mental illness. Data were collected in Toronto, Ontario, as part of a 4-year national randomized field trial of the Housing First treatment model. Rates of perceived discrimination were captured from survey questions regarding perceived discrimination among 231 ethnoracially diverse participants with moderate mental health needs. The qualitative component included thirty six in-depth interviews which explored how individuals who bear these multiple identities of oppression navigate stigma and discrimination, and what affects their capacity to do so. Quantitative analysis revealed very high rates of perceived discrimination related to: homelessness/poverty (61.5%), race/ethnicity/skin colour (50.6%) and mental illness/substance use (43.7%). Immigrants and those who had been homeless three or more years reported higher perceived discrimination on all three domains. Analysis of qualitative interviews revealed three common themes related to navigating these experiences of discrimination among participants: 1) social distancing; 2) old and new labels/identities; and, 3) 'homeland' cultures. These study findings underscore poverty and homelessness as major sources of perceived discrimination, and expose underlying complexities in the navigation of multiple identities in responding to stigma and discrimination.

Holding Ashley (X): Bestowing Identity Through Caregiving in Profound Intellectual Disability.

PubMed

Freitag, Lisa; Liaschenko, Joan

2017-01-01

The controversy over the so-called Ashley Treatment (AT), a series of medical procedures that inhibited both growth and sexual development in the body of a profoundly intellectually impaired girl, usually centers either on Ashley's rights, including a right to an intact, unaltered body, or on Ashley's parents' rights to make decisions for her. The claim made by her parents, that the procedure would improve their ability to care for her, is often dismissed as inappropriate or, at best, irrelevant. We argue, however, that caregiving is a central issue in the controversy, as Ashley's need for caregiving is a defining characteristic of her life. In this article, we analyze the ethics of the Ashley Treatment within the context of family caregiving. Through the physical and emotional work of caregiving, families participate in the formation and maintenance of personal identity, a process that Hilde Lindemann recently called "holding." We argue that, in an intellectually disabled person such as Ashley, who depends on her family for every aspect of her care, the family's contribution to identity is an essential source of personhood. We believe that the treatment can be justified if it is indeed an instance of appropriate family "holding" for Ashley. Copyright 2017 The Journal of Clinical Ethics. All rights reserved.

Cannabis use and 'safe' identities in an inner-city school risk environment.

Despite evidence of school effects on drug use, little is known about the social and institutional processes through which these may occur. This study explores how school experiences may shape young people's drug-related attitudes and actions and adds to existing evidence highlighting the importance of drug use in young people's identity construction and group bonding. Case study qualitative data were collected through semi-structured interviews supplemented with observations. Fourteen students aged 14-15 were interviewed in autumn 2006 and again in summer 2007. Five teachers were interviewed. Inner-city secondary schools may constitute risky and insecure environments, and thereby act as structural forces in shaping how students form peer groups and respond to feelings of insecurity. Cannabis use--and identities constructed in relation to this--appeared to play a key role in how students manage insecurity. Black and dual-heritage students formed large, 'safe' ethno-centric school social networks and smoking 'weed' appeared to be an important source of bonding and identity. For some students, a vicious circle may exist whereby the process of 'fitting in' exacerbates difficult and conflicting relationships with teachers and parents, entrenches disengagement from education and leads to further cannabis use. There also appeared to be a diffusion of this 'safe' identity construction beyond these disengaged students. Cannabis and other drug use may also be an important safety strategy and source of bonding for pro-education students who need to be seen 'getting high' as well as 'aiming high'. While some students constructed 'safe' and 'sweet' identities others were constrained by their position and resources at school. Inner-city schools may both reflect and reproduce existing patterns of drug use. The concept of risk hierarchies may be important when designing and evaluating school-based drug-prevention strategies.

Annoyance by transportation noise: The effects of source identity and tonal components.

PubMed

White, Kim; Bronkhorst, Adelbert W; Meeter, Martijn

2017-05-01

Aircraft noise is consistently rated as more annoying than noise from other sources with similar intensity. In three experiments, it was investigated whether this penalty is due to the source identity of the noise. In the first experiment, four samples were played to participants engaged in a working memory task: road traffic noise, an Airbus 320 flyover, and unidentifiable, transformed versions of these samples containing the same spectral content and envelope. Original, identifiable samples were rated as more annoying than the transformed samples. A second experiment tested whether these results were due to the absence of tonal components in the transformed samples. This was partly the case: an additional sample, created from the A320 flyover by filtering out major tonal components, was rated as less annoying than the original A320 sample, but as more annoying than the transformed sample. In a third experiment, participants either received full disclosure of the generation of the samples or no information to identify the transformed samples. The transformed sample was rated as most annoying when the A320 identity was disclosed, but as least annoying when it was not. Therefore, it was concluded that annoyance is influenced by both identifiability and the presence of tonal components.

Group membership and social identity in addiction recovery.

PubMed

Buckingham, Sarah A; Frings, Daniel; Albery, Ian P

2013-12-01

Despite a growing interest in how group membership can positively impact health, little research has addressed directly the role social identity processes can have on recovery from addiction. Drawing on social identity theory and self-categorization theory, the present study investigated how recovery group membership can introduce a new social identity associated with recovery, compared to the social identity associated with addiction. We hypothesized that two processes--evaluative differentiation and identity preference--would be linked with higher self-efficacy and positive health outcomes (i.e., reduced relapse, lower levels of appetitive behavior, and elevated feelings of social connectedness [Study 2]). Study 1 recruited members (N = 61) from United Kingdom based mutual aid groups of Alcoholics Anonymous and Narcotics Anonymous. Study 2 recruited ex-smokers (N = 81) from online sources. In Study 1, evaluative differentiation was significantly related to lowered relapse and reduced appetitive behavior. Identity preference was related to higher levels of self-efficacy, which was related to months drug-free and reduced levels of appetitive behaviors. In Study 2, evaluative differentiation was related to identity preference. Identity preference was also related to higher self-efficacy, which in turn was related to lower relapse. Although exploratory, these results suggest that developing a social identity as a "recovering addict" or an "ex-smoker" and subsequently highlighting the difference between such identities may be a useful strategy for reducing relapse among people with problems associated with addictive behaviors.

GCM Simulation of the Large-scale North American Monsoon Including Water Vapor Tracer Diagnostics

NASA Technical Reports Server (NTRS)

Bosilovich, Michael G.; Schubert, Siegfried D.; Sud, Yogesh; Walker, Gregory K.

2002-01-01

In this study, we have applied GCM water vapor tracers (WVT) to simulate the North American water cycle. WVTs allow quantitative computation of the geographical source of water for precipitation that occurs anywhere in the model simulation. This can be used to isolate the impact that local surface evaporation has on precipitation, compared to advection and convection. A 15 year 1 deg, 1.25 deg. simulation has been performed with 11 global and 11 North American regional WVTs. Figure 1 shows the source regions of the North American WVTs. When water evaporates from one of these predefined regions, its mass is used as the source for a distinct prognostic variable in the model. This prognostic variable allows the water to be transported and removed (precipitated) from the system in an identical way that occurs to the prognostic specific humidity. Details of the model are outlined by Bosilovich and Schubert (2002) and Bosilovich (2002). Here, we present results pertaining to the onset of the simulated North American monsoon.

Cultivable Actinobacteria are the largest source of microbially derived bioactive molecules. The high demand for novel antibiotics highlights the need for exploring novel sources of these bacteria. Microbial symbioses with sessile macro-organisms, known to contain bioactive compounds likely of bacterial origin, represent an interesting and underexplored source of Actinobacteria. We studied the diversity and potential for bioactive-metabolite production of Actinobacteria associated with two marine lichens (Lichina confinis and L. pygmaea; from intertidal and subtidal zones) and one littoral lichen (Roccella fuciformis; from supratidal zone) from the Brittany coast (France), as well as the terrestrial lichen Collema auriforme (from a riparian zone, Austria). A total of 247 bacterial strains were isolated using two selective media. Isolates were identified and clustered into 101 OTUs (98% identity) including 51 actinobacterial OTUs. The actinobacterial families observed were: Brevibacteriaceae, Cellulomonadaceae, Gordoniaceae, Micrococcaceae, Mycobacteriaceae, Nocardioidaceae, Promicromonosporaceae, Pseudonocardiaceae, Sanguibacteraceae and Streptomycetaceae. Interestingly, the diversity was most influenced by the selective media rather than lichen species or the level of lichen thallus association. The potential for bioactive-metabolite biosynthesis of the isolates was confirmed by screening genes coding for polyketide synthases types I and II. These results show that littoral lichens are a source of diverse potentially bioactive Actinobacteria.

During the autumn and winter of 2004 and 2005, an extensive outbreak of waterborne giardiasis occurred in Bergen, Norway. Over 1,500 patients were diagnosed with giardiasis. Analysis of water from the implicated source revealed low numbers of Giardia cysts, but the initial contamination event probably occurred up to 10 weeks previously. While sewage leakage from a residential area is now considered to be the probable source of contamination, during the episode waste from one particular septic tank was thought to be a possible source. Genotyping of cysts from the septic tank demonstrated that they were assemblage A cysts, although the sequences were not identical to any previously published sequences. For the β-giardin gene, the closest published subgenotype was subgenotype A3; for the gdh gene, the closest published subgenotype was subgenotype A2. Genotyping of cysts from 21 patient samples revealed that they were assemblage B cysts; thus, the septic tank was unlikely to be the contamination source. Sequencing of the β-giardin and gdh genes from patient samples and a comparison of the sequences gave complex results. For the β-giardin gene, three isolates had sequences identical to subgenotype B3 sequences. However, other isolates had between one and four single-nucleotide polymorphisms (SNPs). For the gdh gene, none of the sequences were identical to the sequence published for subgenotype B3, and the sequences had between one and three SNPs. One isolate, which was identical to subgenotype B3 at the β-giardin gene, was more similar to subgenotype B2 at the gdh gene. Grouping the isolates on the basis of SNPs resulted in different groups for the two genes. The results are discussed in relation to giardiasis in Norway and to other Giardia genotyping studies.

Dehalococcoides spp. are an industrially relevant group of Chloroflexi bacteria capable of reductively dechlorinating contaminants in groundwater environments. Existing Dehalococcoides genomes revealed a high level of sequence identity within this group, including 98 to 100% 16S rRNA sequence identity between strains with diverse substrate specificities. Common molecular techniques for identification of microbial populations are often not applicable for distinguishing Dehalococcoides strains. Here we describe an oligonucleotide microarray probe set designed based on clustered Dehalococcoides genes from five different sources (strain DET195, CBDB1, BAV1, and VS genomes and the KB-1 metagenome). This "pangenome" probe set provides coverage of core Dehalococcoides genes as well as strain-specific genes while optimizing the potential for hybridization to closely related, previously unknown Dehalococcoides strains. The pangenome probe set was compared to probe sets designed independently for each of the five Dehalococcoides strains. The pangenome probe set demonstrated better predictability and higher detection of Dehalococcoides genes than strain-specific probe sets on nontarget strains with <99% average nucleotide identity. An in silico analysis of the expected probe hybridization against the recently released Dehalococcoides strain GT genome and additional KB-1 metagenome sequence data indicated that the pangenome probe set performs more robustly than the combined strain-specific probe sets in the detection of genes not included in the original design. The pangenome probe set represents a highly specific, universal tool for the detection and characterization of Dehalococcoides from contaminated sites. It has the potential to become a common platform for Dehalococcoides-focused research, allowing meaningful comparisons between microarray experiments regardless of the strain examined.

Three fields of discourse regarding a masculine-like woman connect at a point that the queer field calls intersex, medical practice calls a sexual disorder, and rabbinic literature terms aylonit. The queer discursive field focuses on the freedom to choose an identity, but not the freedom from choosing one. The medical field focuses on sexual practice as the source of determining "normal" sexuality. In the discursive field of Jewish law there are no demands, because the Halakhic authority determines gender identity on behalf of the individual, maintaining ambiguity.

This paper presents a case study in which integrated forensic oil fingerprinting and data interpretation techniques were used to characterize the chemical compositions and determine the source of the 2009 Sarnia (Ontario) oil spill incident. The diagnostic fingerprinting techniques include determination of hydrocarbon groups and semi-quantitative product-type screening via gas chromatography (GC), analysis of oil-characteristic biomarkers and the extended suite of parent and alkylated PAH (polycyclic aromatic hydrocarbon) homologous series via gas chromatography-mass spectrometry (GC-MS), determination and comparison of a variety of diagnostic ratios of "source-specific marker" compounds, and determination of the weathering degree of the spilled oil, and whether the spilled oil hydrocarbons have been mixed with any other "background" chemicals (biogenic and/or pyrogenic hydrocarbons). The detailed chemical fingerprinting data and results reveal the following: (1) all four samples are mixtures of diesel and lubricating oil with varying percentages of diesel to lube oil. Both samples 1460 and 1462 are majority diesel-range oil mixed with a smaller portion of lube oil. Sample 1461 contains slightly less diesel-range oil. Sample 1463 is majority lubricating-range oil. (2) The diesel in the four diesel/lube oil mixture samples was most likely the same diesel and from the same source. (3) The spill sample 1460 and the suspected-source sample 1462 have nearly identical concentrations and distribution patterns of target analytes including TPHs, n-alkane, PAHs and biomarker compounds; and have nearly identical diagnostic ratios of target compounds as well. Furthermore, a perfect "positive match" correlation line (with all normalized ratio data points falling into the straight correlation line) is clearly demonstrated. It is concluded that the spill oil water sample 1460 (#1, from the water around the vessel enclosed by a boom) matches with the suspected source sample 1462 (#3, from the vessel engine room bilge pump). (4) From the n-alkane and PAH analysis, it appears that the oil in the spill sample 1460 is slightly more weathered in comparison with sample 1462. The minor differences in fingerprints of two samples were most likely caused by weathering effects. (5) Sample 1461 (#2, from the vessel engine room bilge) and sample 1463 (#4, from the vessel bilge waste collection tank) demonstrated significantly different fingerprints and diagnostic ratios of target compounds from that of spill sample 1460. This was caused most likely by percentages of diesel to lube oil in these two samples different from that in spill sample 1460.

Science education reform in Confucian learning cultures: teachers' perspectives on policy and practice in Taiwan

NASA Astrophysics Data System (ADS)

Huang, Ying-Syuan; Asghar, Anila

2018-03-01

This empirical study investigates secondary science teachers' perspectives on science education reform in Taiwan and reflects how these teachers have been negotiating constructivist and learner-centered pedagogical approaches in contemporary science education. It also explores the challenges that teachers encounter while shifting their pedagogical focus from traditional approaches to teaching science to an active engagement in students' learning. Multiple sources of qualitative data were obtained, including individual interviews with science teachers and teachers' reflective journals about Confucianism in relation to their educational philosophies. Thematic analysis and constant comparative method were used to analyze the data. The findings revealed that Confucian traditions play a significant role in shaping educational practices in Taiwan and profoundly influence teachers' epistemological beliefs and their actual classroom practice. Indeed, science teachers' perspectives on Confucian learning traditions played a key role in supporting or obstructing their pedagogical commitments to inquiry-based and learner-centered approaches. This study draws on the literature concerning teachers' professional struggles and identity construction during educational reform. Specifically, we explore the ways in which teachers respond to educational changes and negotiate their professional identities. We employed various theories of identity construction to understand teachers' struggles and challenges while wrestling with competing traditional and reform-based pedagogical approaches. Attending to these struggles and the ways in which they inform the development of a teacher's professional identity is vital for sustaining current and future educational reform in Taiwan as well as in other Eastern cultures. These findings have important implications for teachers' professional development programs in East Asian cultures.

Evaluation of the impact of genetic linkage in forensic identity and relationship testing for expanded DNA marker sets.

PubMed

Tillmar, Andreas O; Phillips, Chris

2017-01-01

Advances in massively parallel sequencing technology have enabled the combination of a much-expanded number of DNA markers (notably STRs and SNPs in one or combined multiplexes), with the aim of increasing the weight of evidence in forensic casework. However, when data from multiple loci on the same chromosome are used, genetic linkage can affect the final likelihood calculation. In order to study the effect of linkage for different sets of markers we developed the biostatistical tool ILIR, (Impact of Linkage on forensic markers for Identity and Relationship tests). The ILIR tool can be used to study the overall impact of genetic linkage for an arbitrary set of markers used in forensic testing. Application of ILIR can be useful during marker selection and design of new marker panels, as well as being highly relevant for existing marker sets as a way to properly evaluate the effects of linkage on a case-by-case basis. ILIR, implemented via the open source platform R, includes variation and genomic position reference data for over 40 STRs and 140 SNPs, combined with the ability to include additional forensic markers of interest. The use of the software is demonstrated with examples from several different established marker sets (such as the expanded CODIS core loci) including a review of the interpretation of linked genetic data.

Patient and tissue identification in the assisted reproductive technology laboratory.

PubMed

Pomeroy, Kimball O; Racowsky, Catherine

2012-06-01

Several high-profile cases involving in vitro fertilization have recently received considerable media attention and highlight the importance of assuring patient and tissue identification. Within the assisted reproductive technology (ART) laboratory, there are many steps where wrong patient or tissue identity could have drastic results. Erroneous identity can result in tragic consequences for the patient, the laboratory, and for those working in the program as a whole. Such errors can result in enormous psychological and financial costs, as well as a loss in confidence. There are several critical steps that should be taken every single time and for each specific procedure performed in the ART laboratory to ensure the correct identification of patients and their tissue. These steps should be detailed in protocols that include the method of identification, the two unique identifiers that will be used, the sources of these identifiers, and often a system in which more than one person is involved in the identification. Each protocol should ideally include a checklist that is actively used for the implementation of each procedure. The protocol should also indicate what to do if the identification does not match up, including rapid handling and notification of the patient involved in the error. All ART laboratories should instill in their employees an atmosphere of full and open disclosure for cases where mistakes are made.

Cerami, Ethan G; Bader, Gary D; Gross, Benjamin E; Sander, Chris

2006-11-13

Biological pathways, including metabolic pathways, protein interaction networks, signal transduction pathways, and gene regulatory networks, are currently represented in over 220 diverse databases. These data are crucial for the study of specific biological processes, including human diseases. Standard exchange formats for pathway information, such as BioPAX, CellML, SBML and PSI-MI, enable convenient collection of this data for biological research, but mechanisms for common storage and communication are required. We have developed cPath, an open source database and web application for collecting, storing, and querying biological pathway data. cPath makes it easy to aggregate custom pathway data sets available in standard exchange formats from multiple databases, present pathway data to biologists via a customizable web interface, and export pathway data via a web service to third-party software, such as Cytoscape, for visualization and analysis. cPath is software only, and does not include new pathway information. Key features include: a built-in identifier mapping service for linking identical interactors and linking to external resources; built-in support for PSI-MI and BioPAX standard pathway exchange formats; a web service interface for searching and retrieving pathway data sets; and thorough documentation. The cPath software is freely available under the LGPL open source license for academic and commercial use. cPath is a robust, scalable, modular, professional-grade software platform for collecting, storing, and querying biological pathways. It can serve as the core data handling component in information systems for pathway visualization, analysis and modeling.

2017-01-01

Background A growing body of research has examined transgender identity development, but no studies have investigated developmental pathways as a transactional process between youth and caregivers, incorporating perspectives from multiple family members. The aim of this study was to conceptualize pathways of transgender identity development using narratives from both transgender and gender nonconforming (TGN) youth and their cisgender (non-transgender) caregivers. Methods The sample included 16 families, with 16 TGN youth, ages 7–18 years, and 29 cisgender caregivers (N = 45 family members). TGN youth represented multiple gender identities, including trans boy (n = 9), trans girl (n = 5), gender fluid boy (n = 1), and girlish boy (n = 1). Caregivers included mothers (n = 17), fathers (n = 11), and one grandmother. Participants were recruited from LGBTQ community organizations and support networks for families with transgender youth in the Midwest, Northeast, and South regions of the United States. Each family member completed a one-time in-person semi-structured qualitative interview that included questions about transgender identity development. Results Analyses revealed seven overarching themes of transgender identity development, which were organized into a conceptual model: Trans identity development, sociocultural influences/societal discourse, biological influences, family adjustment/impact, stigma/cisnormativity, support/resources, and gender affirmation/actualization. Conclusions Findings underscore the importance of assessing developmental processes among TGN youth as transactional, impacting both youth and their caregivers. PMID:29527139

2011-01-01

Due to disparities in the use of genetic services, there has been growing interest in examining beliefs and attitudes related to genetic testing for breast and/or ovarian cancer risk among women of African descent. However, to date, few studies have addressed critical cultural variations among this minority group and their influence on such beliefs and attitudes. We assessed ethnic, racial and cultural identity and examined their relationships with perceived benefits and barriers related to genetic testing for cancer risk in a sample of 160 women of African descent (49% self-identified African American, 39% Black-West Indian/Caribbean, 12% Black-Other) who met genetic risk criteria and were participating in a larger longitudinal study including the opportunity for free genetic counseling and testing in New York City. All participants completed the following previously validated measures: (a) the multi-group ethnic identity measure (including ethnic search and affirmation subscales) and other-group orientation for ethnic identity, (b) centrality to assess racial identity, and (c) Africentrism to measure cultural identity. Perceived benefits and barriers related to genetic testing included: (1) pros/advantages (including family-related pros), (2) cons/disadvantages (including family-related cons, stigma and confidentiality concerns), and (3) concerns about abuses of genetic testing. In multivariate analyses, several ethnic identity elements showed significant, largely positive relationships to perceived benefits about genetic testing for breast and/or ovarian cancer risk, the exception being ethnic search, which was positively associated with cons/disadvantages, in general, and family-related cons/disadvantages. Racial identity (centrality) showed a significant association with confidentiality concerns. Cultural identity (Africentrism) was not related to perceived benefits and/or barriers. Ethnic and racial identity may influence perceived benefits and barriers related to genetic testing for breast and/or ovarian cancer risk among at-risk women of African descent. Genetic counseling services may want to take into account these factors in the creation of culturally-appropriate services which best meet the needs of this heterogenous population.

Natural Colorants: Food Colorants from Natural Sources.

PubMed

Sigurdson, Gregory T; Tang, Peipei; Giusti, M Mónica

2017-02-28

The color of food is often associated with the flavor, safety, and nutritional value of the product. Synthetic food colorants have been used because of their high stability and low cost. However, consumer perception and demand have driven the replacement of synthetic colorants with naturally derived alternatives. Natural pigment applications can be limited by lower stability, weaker tinctorial strength, interactions with food ingredients, and inability to match desired hues. Therefore, no single naturally derived colorant can serve as a universal alternative for a specified synthetic colorant in all applications. This review summarizes major environmental and biological sources for natural colorants as well as nature-identical counterparts. Chemical characteristics of prevalent pigments, including anthocyanins, carotenoids, betalains, and chlorophylls, are described. The possible applications and hues (warm, cool, and achromatic) of currently used natural pigments, such as anthocyanins as red and blue colorants, and possible future alternatives, such as purple violacein and red pyranoanthocyanins, are also discussed.

The nature of stress experienced by lesbians and gay men.

PubMed

Iwasaki, Yoshitaka; Ristock, Janice L

2007-09-01

This study examined both the meanings and sources/causes of stress from the perspectives of lesbians and gay men (n=30), using a series of focus groups. The findings suggest that stress is considered a part of life itself, and is perceived to contain both negative (e.g. detrimental effects on health and overall functioning, unfairness, out-of-control), and positive (e.g. a motivator, growth-facilitator) elements. The sources/causes of stress (i.e. stressors) identified include stress experienced from the "coming out" process, stress in family relations and intimate relationships, conflict over one's sexuality given society's homophobic and heterosexist attitudes toward lesbians and gay men, as well as stress from financial and work-related issues. More importantly, this study suggests that culture/ethnicity, gender, and aging, which are interconnected with one's sexual identity, play an important role in shaping the experiences of stress among lesbians and gay men.

A review of the theory of trailing edge noise

Howe, M. S.

1978-01-01

Literature on the theory of the generation of sound by the interaction of low Mach number turbulent flow with the edge of a semi-infinite rigid plate is critically reviewed. Three different approaches to the subject are identified, consisting of theories based on (1) Lighthill's acoustic analogy; (2) the solution of special, linearized hydroacoustic problems; and (3) ad hoc aerodynamic source models. When appropriately interpreted, all relevant theories produce essentially identical predictions in the limit of very small Mach numbers. None of the theories discusses the implications of the Kutta condition, however, nor of the effect of forward flight and source motion relative to the trailing edge. An outline of a redevelopment of the theory is included to give a unified view of the problem, exhibit the significance of the various approximations, and incorporate the effect of mean motion and of the Kutta condition.

Little is known about teen fathers though they are found to be disproportionately represented among incarcerated youth. SOURCE USED: This article is developed from a qualitative pilot study of adolescent fathers in the justice system. The authors theorize about teen fathers and the process by which they accept, reject, or are "barriered" from a father identity and role. Adolescence as a developmental period during which an identity is forming is viewed in concert with the concept of hegemonic masculinity and the concept of intersectionality. Risk factors in childhood and adolescence complete the conceptual model through which incarcerated adolescent fathers can be examined. © 2011 Wiley Periodicals, Inc.

Rogers, Leoandra Onnie; Zosuls, Kristina M; Halim, May Ling; Ruble, Diane; Hughes, Diane; Fuligni, Andrew

2012-04-01

Social identity, including identification with one's ethnic group, is an important aspect of social development. However, little is known about the subjective meaning associated with social group memberships, particularly during middle childhood. Using second- and fourth-graders responses to an open-ended question, we explored the meaning of ethnic identity with a sample of Chinese, Dominican, Russian, White, and Black American children. Analyses revealed that middle childhood is an active period for meaning making as children described the ethnic identity to include ideas such as language, physical appearance, pride, relative social position, and culture. While there were few differences in the ethnic identity meaning responses of second- and fourth-grade children, the meaning of ethnic identity varied considerably across the ethnic groups underscoring how the unique features and experiences of different ethnic groups shapes the subjective meaning of ethnic identity. These findings align with prior research on the meaning of ethnic identity among adults and adolescents and offer insight for future research regarding the conceptualization and measurement of the meaning of social group membership.

Historical outbreaks can be an important source of information in the understanding of norovirus evolution and epidemiology. Here, we revisit an outbreak of undiagnosed gastroenteritis that occurred in Shippensburg, Pennsylvania in 1972. Nearly 5000 people fell ill over the course of 10 days. Symptoms included diarrhea, vomiting, stomach cramps, and fever, lasting for a median of 24 h. Using current techniques, including next-generation sequencing of full-length viral genomic amplicons, we identified an unusual norovirus recombinant (GII.Pg/GII.3) in nine of 15 available stool samples from the outbreak. This particular recombinant virus has not been reported in recent decades, although GII.3 and GII.Pg genotypes have been detected individually in current epidemic strains. The consensus nucleotide sequences were nearly identical among the four viral genomes analysed, although each strain had three to seven positions in the genome with heterogenous non-synonymous nucleotide subpopulations. Two of these resulting amino acid polymorphisms were conserved in frequency among all four cases, consistent with common source exposure and successful transmission of a mixed viral population. Continued investigation of variant nucleotide populations and recombination events among ancestral norovirus strains such as the Shippensburg virus may provide unique insight into the origin of contemporary strains.

The current study used mixed methods to research pre-service teachers’ professional identity. Ninety-eight pre-service teachers were investigated and twelve teachers were interviewed in China. The results were as follows: (1) The results of quantitative data showed that compared with before the field teaching practice, pre-service teachers’ professional identity increased after the field teaching practice—specifically, intrinsic value identity increased, and extrinsic value identity did not significantly change; (2) The results of qualitative data validated and elaborated the results of quantitative data in more detail with regard to changes in professional identity. Specifically, compared with before the field teaching practice, intrinsic value identity including work content, work pattern, etc., increased and extrinsic value identity including work environment, income, and social status, etc., did not significantly change after experiencing teaching practice; (3) The results of qualitative data also showed that mentor support at field school promoted the development of pre-service teachers’ professional identity. Moreover, the development of pre-service teachers’ professional identity during field teaching practice further promoted their professional commitment; that is, it promoted their emotional evaluation and belief in the teaching profession. The study discussed these results and proposed solutions and suggestions for future studies. PMID:28790956

Data from two contexts, i.e. the European Unresectable Neuroblastoma (EUNB) clinical trial and results from comparative genomic hybridisation (CGH) analyses from corresponding tumour samples shall be provided to existing repositories for secondary use. Utilizing the European Unified Patient IDentity Management (EUPID) as developed in the course of the ENCCA project, the following processes were applied to the data: standardization (providing interoperability), pseudonymization (generating distinct but linkable pseudonyms for both contexts), and linking both data sources. The applied procedures resulted in a joined dataset that did not contain any identifiers that would allow to backtrack the records to either data sources. This provided a high degree of privacy to the involved patients as required by data protection regulations, without preventing proper analysis.

Recollections of Childhood Religious Identity and Behavior as a Function of Adult Religiousness

2012-01-01

People have a strong motivation to maintain a self-concept that is coherent and consistent over time. Religion is an central source of social identity for many people, but its importance is prone to dramatic change across the life course. To maintain a consistent perception of self, recollections of one’s own past religiousness may shift to better fit with the present. This study examined changes between early and middle adulthood in retrospective perceptions of religious behavior and identity in childhood. Data from a population-based birth cohort sample were matched with data from individuals who participated in at least two of three adult follow-up studies, at intervals of approximately 10 years. Logistic regression was used to analyze the association of final recollections of childhood behavior and identity with previous recollections and current religious characteristics. Consistent with the predictions of temporal self-appraisal theory, participants’ perception of their religious identity as children tended to change over time to match their adult religious identity. Recollections of childhood religious behavior were more stable than recollections of religious identity, and change was unrelated to adult behavior. These results have implications for studying religious characteristics using retrospective measures, regarding their accuracy and their independence from contemporary measures. PMID:22844186

Density and white light brightness in looplike coronal mass ejections - Temporal evolution

Steinolfson, R. S.; Hundhausen, A. J.

1988-01-01

Three ambient coronal models suitable for studies of time-dependent phenomena were used to investigate the propagation of coronal mass ejections initiated in each atmosphere by an identical energy source. These models included those of a static corona with a dipole magnetic field, developed by Dryer et al. (1979); a steady polytropic corona with an equatorial coronal streamer, developed by Steinolfson et al. (1982); and Steinolfson's (1988) model of heated corona with an equatorial coronal streamer. The results indicated that the first model does not adequately represent the general characteristics of observed looplike mass ejections, and the second model simulated only some of the observed features. Only the third model, which included a heating term and a streamer, was found to yield accurate simulation of the mess ejection observations.

A plasma generator includes a pair of identical spiraled electrical conductors separated by dielectric material. Both spiraled conductors have inductance and capacitance wherein, in the presence of a time-varying electromagnetic field, the spiraled conductors resonate to generate a harmonic electromagnetic field response. The spiraled conductors lie in parallel planes and partially overlap one another in a direction perpendicular to the parallel planes. The geometric centers of the spiraled conductors define endpoints of a line that is non-perpendicular with respect to the parallel planes. A voltage source coupled across the spiraled conductors applies a voltage sufficient to generate a plasma in at least a portion of the dielectric material.

The results of a study to investigate the feasibility of manufacturing photovoltaic solar array modules by the use of energy obtained from similar or identical photovoltaic sources are presented. The primary objective of this investigation was the characterization of the energy requirements of current and developing technologies which comprise the photovoltaic field. For cross-checking the energies of prevailing technologies data were also used and the wide-range assessment of alternative technologies included different refinement methods, various ways of producing light sheets, semicrystalline cells, etc. Energy data are utilized to model the behavior of a future solar breeder plant under various operational conditions.

Simple Peer-to-Peer SIP Privacy

Koskela, Joakim; Tarkoma, Sasu

In this paper, we introduce a model for enhancing privacy in peer-to-peer communication systems. The model is based on data obfuscation, preventing intermediate nodes from tracking calls, while still utilizing the shared resources of the peer network. This increases security when moving between untrusted, limited and ad-hoc networks, when the user is forced to rely on peer-to-peer schemes. The model is evaluated using a Host Identity Protocol-based prototype on mobile devices, and is found to provide good privacy, especially when combined with a source address hiding scheme. The contribution of this paper is to present the model and results obtained from its use, including usability considerations.

Emotional facial expressions reduce neural adaptation to face identity.

2014-05-01

In human social interactions, facial emotional expressions are a crucial source of information. Repeatedly presented information typically leads to an adaptation of neural responses. However, processing seems sustained with emotional facial expressions. Therefore, we tested whether sustained processing of emotional expressions, especially threat-related expressions, would attenuate neural adaptation. Neutral and emotional expressions (happy, mixed and fearful) of same and different identity were presented at 3 Hz. We used electroencephalography to record the evoked steady-state visual potentials (ssVEP) and tested to what extent the ssVEP amplitude adapts to the same when compared with different face identities. We found adaptation to the identity of a neutral face. However, for emotional faces, adaptation was reduced, decreasing linearly with negative valence, with the least adaptation to fearful expressions. This short and straightforward method may prove to be a valuable new tool in the study of emotional processing.

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.

Integrating Identity Management With Federated Healthcare Data Models

NASA Astrophysics Data System (ADS)

Hu, Jun; Peyton, Liam

In order to manage performance and provide integrated services, health care data needs to be linked and aggregated across data sources from different organizations. The Internet and secure B2B networks offer the possibility of providing near real-time integration. However, there are three major stumbling blocks. One is to standardize and agree upon a common data model across organizations. The second is to match identities between different locations in order to link and aggregate records. The third is to protect identity and ensure compliance with privacy laws. In this paper, we analyze three main approaches to the problem and use a healthcare scenario to illustrate how each one addresses different aspects of the problem while failing to address others. We then present a systematic framework in which the different approaches can be flexibly combined for a more comprehensive approach to integrate identity management with federated healthcare data models.

Genetics and education: the ethics of shaping human identity.

PubMed

Ravitsky, Vardit

2002-10-01

This paper suggests an analogy between education and genetic interventions as means of shaping the identity of children and future adults. It proposes to look at issues discussed in the philosophy of education as a possible source of insight for ethical guidelines regarding future genetic interventions. The paper focuses on situations of conflict between parents and state regarding the authority to determine the child s best interests. It describes the current formulation of the conflict in the literature as lacking the crucial element of the child s right to a cultural identity. It argues that this element is a necessary component in an ethical analysis of the child s best interests in a multicultural, liberal society which respects diversity. The paper therefore proposes a better model for the moral evaluation of identity-shaping decisions and offers some implications of this model for genetics.

Adolescent identity development and distress in a clinical sample.

Wiley, Rachel E; Berman, Steven L

2013-12-01

The purpose of this study was to examine the relationships of identity development and identity distress to psychological adjustment within adolescents affected by psychological problems. Participants included 88 adolescents (43.2% female) ranging from 11 to 20 years of age who were receiving services from a community mental health center. A high proportion of the participants (22.7%) met the Diagnostic and Statistical Manual of Mental Disorders Fourth Edition Text Revision criteria for Identity Problem. Regression analyses found psychopathology symptom score was associated with identity distress, identity exploration, and identity commitment, while identity distress was only related to psychopathology symptom score and not the other two identity variables. Adolescents with a clinical diagnosis may report significant levels of identity distress. Given that the relationship between psychopathology and identity distress may be reciprocal, assessing for identity issues might be prudent when conducting clinical diagnostic interviews and useful in treatment planning. © 2013 Wiley Periodicals, Inc.

Gender Identity and Sex-of-rearing in Children with Disorders of Sexual Differentiation

PubMed Central

2006-01-01

Aim: To compare declared sexual identity to sex-of-rearing in individuals with disorders of sexual differentiation. Methods: All 84 patients ≥5 years old in a pediatric psychosexual development clinic were assessed for sex-of-rearing and sexual identity. Diagnoses included 1) male-typical prenatal androgen effects but an absent or severely inadequate penis - 45 patients with cloacal exstrophy or aphallia; 2) inadequate prenatal androgens and a Y-chromosome - 28 patients with partial androgen insensitivity (pAIS) mixed gonadal dysgenesis (MGD), hermaphroditism, or craniofacial anomalies with genital ambiguity; 3) inappropriate prenatal androgen effects and a 46,XX karyotype - 11 patients with congenital adrenal hyperplasia (CAH). Results: Of 73 patients with disordered sexual differentiation and a Y-chromosome, 60 were reared female 26 of the 60 (43%) declared female identity while 32 (53%) declared male identity including 18 (55%) with cloacal exstrophy, six (55%) with MGD, four (40%) with pAIS, one (50%) with aphallia, one (100%) with hermaphroditism, and two (67%) with craniofacial anomalies; two (3%) declined to discuss identity. Nine of 11 patients with CAH and a 46,XX karyotype were reared female and two reared male; six (55%) declared female identity and five (45%) declared male identity. Of 84 total patients, 69 were reared female, but only 32 lived as female, while 29 lived as male; four patients refused to discuss sex-of-living; parents of four patients rejected their declarations of male identity. All 15 patients reared male lived as male including two genetic females. Conclusion: Active prenatal androgen effects appeared to dramatically increase the likelihood of recognition of male sexual identity independent of sex-of-rearing. Genetic males with maletypical prenatal androgen effects should be reared male. PMID:16042322

A method and system for detecting, locating and quantifying a physical phenomena such as strain or a deformation in a structure. A plurality of laterally adjacent conductors may each include a plurality of segments. Each segment is constructed to exhibit a unit value representative of a defined energy transmission characteristic. A plurality of identity groups are defined with each identity group comprising a plurality of segments including at least one segment from each of the plurality of conductors. The segments contained within an identity group are configured and arranged such that each of their associated unit values may be represented by a concatenated digit string which is a unique number relative to the other identity groups. Additionally, the unit values of the segments within an identity group maintain unique ratios with respect to the other unit values in the identity group.

Physics career intentions: The effect of physics identity, math identity, and gender

Although nearly half of high school physics students are female, only 21% of physics bachelor's degrees are earned by women. Using data from a national survey of college students in introductory English courses (on science-related experiences, particularly in high school), we examine the influence of students' physics and math identities on their choice to pursue a physics career. Males have higher math and physics identities than females in all three dimensions of our identity framework. These dimensions include: performance/competence (perceptions of ability to perform/understand), recognition (perception of recognition by others), and interest (desire to learn more). A regression model predicting students' intentions to pursue physics careers shows, as expected, that males are significantly more likely to choose physics than females. Surprisingly, however, when physics and math identity are included in the model, females are shown to be equally likely to choose physics careers as compared to males.

Global identification predicts gay-male identity integration and well-being among Turkish gay men.

PubMed

Koc, Yasin; Vignoles, Vivian L

2016-12-01

In most parts of the world, hegemonic masculinity requires men to endorse traditional masculine ideals, one of which is rejection of homosexuality. Wherever hegemonic masculinity favours heterosexuality over homosexuality, gay males may feel under pressure to negotiate their conflicting male gender and gay sexual identities to maintain positive self-perceptions. However, globalization, as a source of intercultural interaction, might provide a beneficial context for people wishing to create alternative masculinities in the face of hegemonic masculinity. Hence, we tested if global identification would predict higher levels of gay-male identity integration, and indirectly subjective well-being, via alternative masculinity representations for gay and male identities. A community sample of 219 gay and bisexual men from Turkey completed the study. Structural equation modelling revealed that global identification positively predicted gay-male identity integration, and indirectly subjective well-being; however, alternative masculinity representations did not mediate this relationship. Our findings illustrate how identity categories in different domains can intersect and affect each other in complex ways. Moreover, we discuss mental health and well-being implications for gay men living in cultures where they experience high levels of prejudice and stigma. © 2016 The British Psychological Society.

The genus Burkholderia comprises 19 species, including Burkholderia vietnamiensis which is the only known N(2)-fixing species of this bacterial genus. The first isolates of B. vietnamiensis were recovered from the rhizosphere of rice plants grown in a phytotron, but its existence in natural environments and its geographic distribution were not reported. In the present study, most N(2)-fixing isolates recovered from the environment of field-grown maize and coffee plants cultivated in widely separated regions of Mexico were phenotypically identified as B. cepacia using the API 20NE system. Nevertheless, a number of these isolates recovered from inside of maize roots, as well as from the rhizosphere and rhizoplane of maize and coffee plants, showed similar or identical features to those of B. vietnamiensis TVV75(T). These features include nitrogenase activity with 10 different carbon sources, identical or very similar nifHDK hybridization patterns, very similar protein electrophoregrams, identical amplified 16S rDNA restriction (ARDRA) profiles, and levels of DNA-DNA reassociation higher than 70% with total DNA from strain TVV75(T). Although the ability to fix N(2) is not reported to be a common feature among the known species of the genus Burkholderia, the results obtained show that many diazotrophic Burkholderia isolates analyzed showed phenotypic and genotypic features different from those of the known N(2)-fixing species B. vietnamiensis as well as from those of B. kururiensis, a bacterium identified in the present study as a diazotrophic species. DNA-DNA reassociation assays confirmed the existence of N(2)-fixing Burkholderia species different from B. vietnamiensis. In addition, this study shows the wide geographic distribution and substantial capability of N(2)-fixing Burkholderia spp. for colonizing diverse host plants in distantly separated environments.

2005-06-01

Concerns about direct-to-consumer advertisement's (DTCA's) information quality have raised interest in patients' drug information-seeking after DTCA exposure. To identify predictors of patients' intentions and behaviors to seek drug information from physicians, pharmacists, and the Internet after DTCA exposure, using theories of planned behavior and self-efficacy. One thousand patients were randomly selected from 3,000 nationwide osteoarthritic patients. A self-administered survey examined predictors of intention including measurements of attitude toward behavior, subjective norm, perceived difficulty, self-efficacy, controllability, self-identity, intention, exposure to ads, and control variables. After 6 weeks, another survey measured respondents' information-seeking behavior. For patients exposed to DTCA, 6 multiple regressions were performed for information-seeking intention and behavior for 3 information sources: physicians, pharmacists, and the Internet. The response rates were 61.9% and 80.1% for the first survey and the second survey, respectively. Four hundred and fifty-four participants reported exposure to DTCA about arthritis prescription medicines in the previous month. Over 41% of the variance in intention and over 18% of the variance in behavior were explained by the regression procedures. The consistent positive predictors of intention were attitude toward behavior, self-identity, attitude toward DTCAs of arthritis medication, and osteoarthritis pain; while the consistent positive predictors of behavior were intention and osteoarthritis pain. The strongest predictors of intention were self-identity for physicians, subjective norm for pharmacists, and attitude toward behavior for the Internet. Perceived difficulty and self-efficacy did not predict intention, and self-efficacy and controllability did not predict behavior. DTCA-prompted drug information-seeking may be under patients' complete volitional control. To promote information searching, efforts could be made to affect factors predicting intention. Interventions could address patients' attitude toward behavior, the influence of their important others, and their role as information seeker, respectively, for information sources like the Internet, pharmacists, and physicians.

'Living with tics': self-experience of adolescents with Tourette syndrome during peer interaction.

To describe the essence of the self-experience of adolescents with Tourette syndrome in the context of peer interaction. Tourette syndrome has an adverse impact on adolescents' physical, psychological and interpersonal interactions. Peers provide adolescents with social interactions that are crucial to the formation of self-identity. Studies exploring the self-experience of adolescents with Tourette syndrome in the context of peer relationships are lacking. A qualitative, phenomenological research design was used. A total of 12 adolescents with Tourette syndrome from the Taiwan Tourette Family Association were selected by purposive sampling. Data were collected using open-ended questions in one-on-one in-depth interviews that lasted 60-90 minutes. Giorgi's phenomenological methods were applied to analyse the data obtained. Four criteria were employed to evaluate methodological rigour. The findings showed that the self-experience of adolescents with Tourette syndrome during peer interaction reflected their lived experiences of peer identity, social identity and self-identity. Themes included: (1) the inexplicable onset of tics during encounters with other people, (2) sources inspiring the courage for self-acceptance and (3) strategies of self-protection in response to changes in situation. The self-experience of peer interaction among adolescents with Tourette syndrome is a dynamic and interactive process characterised by the symbolic meanings conferred on the tics by the interacting adolescents. The adolescents with Tourette syndrome obtain self-identity through peer responses and recognition, while the tolerance, respect and support of parents and teachers spark the adolescents' courage for self-acceptance. Healthcare providers who assist adolescents with Tourette syndrome must understand that tics occur in the context of peer interaction and how this affects the adolescents' relationships with their peers in various life situations. Furthermore, healthcare providers should provide support, respect and offer coping strategies regarding peer interaction based on an understanding of the social dynamics of such peer interactions. © 2016 John Wiley & Sons Ltd.

Method and apparatus for ultra-high-sensitivity, incremental and absolute optical encoding

NASA Technical Reports Server (NTRS)

Leviton, Douglas B. (Inventor)

1999-01-01

An absolute optical linear or rotary encoder which encodes the motion of an object (3) with increased resolution and encoding range and decreased sensitivity to damage to the scale includes a scale (5), which moves with the object and is illuminated by a light source (11). The scale carries a pattern (9) which is imaged by a microscope optical system (13) on a CCD array (17) in a camera head (15). The pattern includes both fiducial markings (31) which are identical for each period of the pattern and code areas (33) which include binary codings of numbers identifying the individual periods of the pattern. The image of the pattern formed on the CCD array is analyzed by an image processor (23) to locate the fiducial marking, decode the information encoded in the code area, and thereby determine the position of the object.

Sustained multifocal attentional enhancement of stimulus processing in early visual areas predicts tracking performance.

PubMed

Störmer, Viola S; Winther, Gesche N; Li, Shu-Chen; Andersen, Søren K

2013-03-20

Keeping track of multiple moving objects is an essential ability of visual perception. However, the mechanisms underlying this ability are not well understood. We instructed human observers to track five or seven independent randomly moving target objects amid identical nontargets and recorded steady-state visual evoked potentials (SSVEPs) elicited by these stimuli. Visual processing of moving targets, as assessed by SSVEP amplitudes, was continuously facilitated relative to the processing of identical but irrelevant nontargets. The cortical sources of this enhancement were located to areas including early visual cortex V1-V3 and motion-sensitive area MT, suggesting that the sustained multifocal attentional enhancement during multiple object tracking already operates at hierarchically early stages of visual processing. Consistent with this interpretation, the magnitude of attentional facilitation during tracking in a single trial predicted the speed of target identification at the end of the trial. Together, these findings demonstrate that attention can flexibly and dynamically facilitate the processing of multiple independent object locations in early visual areas and thereby allow for tracking of these objects.

When the WFC3 IR detector is exposed to a bright source or sources, the sources can appear as afterimages in subsequent exposures, a phenomenon known as persistence. This can affect the science obtained with the IR channel. We have been involved in an effort to predict the brightness of the afterimages so that users can (at a minimum) flag the affected pixels and remove them from their analysis or (even better) subtract the afterimages from their science images to salvage the data. The ability of any model to remove afterimages depends on the degree to which persistence is the same for identical sets of exposures. We investigate possible time variability of persistence in the WFC3 detector using sets of (almost) identical visits comprised of single exposures of Omega Cen followed by a series of darks in which persistence is measured. We analyze 8 data sets, each consisting of two or three identical visits, with stimulus exposures between 49 and 1199 s, and find clear evidence of variability in several of the datasets in darks taken within 1000 s of the stimulus exposure. In most of the datasets, the difference in persistence for saturated pixels in the stimulus exposure is < 0.01 e-/s for darks taken 1000 s after the initial exposure. One of three 274-second visits has significantly more persistence than its two identical visits. Persistence in this visit was higher in all 4 detector quadrants. The persistence in all three visits is well modeled as a power law decay; the visit with higher persistence has a higher power law amplitude. There was nothing unusual about the observing conditions preceding and during each of these visits that can explain the discrepancy in persistence levels. Variation in persistence implies that: (1) Unless and until the source of the variability is understood, any persistence model for the WFC3 array will be limited in its ability to predict persistence in a single observation, and, (2) as a consequence, users should always carefully inspect the results of any attempt to subtract persistence from WFC3 IR data based on a model prediction.

The contribution of two ears to the perception of vertical angle in sagittal planes.

Morimoto, M

2001-04-01

Because the input signals to the left and right ears are not identical, it is important to clarify the role of these signals in the perception of the vertical angle of a sound source at any position in the upper hemisphere. To obtain basic findings on upper hemisphere localization, this paper investigates the contribution of each pinna to the perception of vertical angle. Tests measured localization of the vertical angle in five planes parallel to the median plane. In the localization tests, the pinna cavities of one or both ears were occluded. Results showed that pinna cavities of both the near and far ears play a role in determining the perceived vertical angle of a sound source in any plane, including the median plane. As a sound source shifts laterally away from the median plane, the contribution of the near ear increases and, conversely, that of the far ear decreases. For saggital planes at azimuths greater than 60 degrees from midline, the far ear no longer contributes measurably to the determination of vertical angle.

Nuclear Forensics and Attribution: A National Laboratory Perspective

NASA Astrophysics Data System (ADS)

Hall, Howard L.

2008-04-01

Current capabilities in technical nuclear forensics - the extraction of information from nuclear and/or radiological materials to support the attribution of a nuclear incident to material sources, transit routes, and ultimately perpetrator identity - derive largely from three sources: nuclear weapons testing and surveillance programs of the Cold War, advances in analytical chemistry and materials characterization techniques, and abilities to perform ``conventional'' forensics (e.g., fingerprints) on radiologically contaminated items. Leveraging that scientific infrastructure has provided a baseline capability to the nation, but we are only beginning to explore the scientific challenges that stand between today's capabilities and tomorrow's requirements. These scientific challenges include radically rethinking radioanalytical chemistry approaches, developing rapidly deployable sampling and analysis systems for field applications, and improving analytical instrumentation. Coupled with the ability to measure a signature faster or more exquisitely, we must also develop the ability to interpret those signatures for meaning. This requires understanding of the physics and chemistry of nuclear materials processes well beyond our current level - especially since we are unlikely to ever have direct access to all potential sources of nuclear threat materials.

Being differently the same: the mediation of identity tensions in the sharing of illness experiences.

The sharing of experiences between patients has become increasingly privileged as a source of knowledge and support in contemporary healthcare. Despite this, relatively little is known about the processes whereby people's experiences become, or fail to become, valued as sources of health-related knowledge in different contexts. Through a secondary analysis of 87 interviews conducted between 2006 and 2008 in the UK with people affected by motor neurone disease (46 interviews) and Parkinson's disease (41 interviews), we explore the identity work involved in turning other people's experiences into 'experiential knowledge' that can be shared between patients. Of particular interest is how the turning of others' experiences into knowledge is presupposed by negotiating a particular type of identity tension - what, drawing on the work of Paul Ricoeur (2003) on metaphor, we refer to as 'being differently the same'. We examine the way in which people living with motor neurone disease and Parkinson's disease spoke of managing this tension as part of the process of accessing and valuing other patients' experiences, both epistemologically and emotionally. Instead of treating others' experiences as a pre-given source of knowledge, we emphasise how experience comes to be embodied and articulated through different media - bodies, speech, text, and images. Moreover, we suggest that paying closer attention to these media provides opportunities for enhancing our understanding of how people with different chronic and/or terminal illnesses use or do not use different forms of peer support - and in particular online ones - as a source of health-related experiential knowledge. Some of the implications of this are discussed in the specific context of people diagnosed with incurable neurodegenerative conditions characterised by visible physical deterioration and associated emotional distress.

McEachern, Aiden; Cholewa, David

2017-01-01

The Government of Alberta continues to improve delivery of healthcare by allowing Albertans to access their health information online. Alberta is the only province in Canada with provincial electronic health records for all its citizens. These records are currently made available to medical practitioners, but Alberta Health believes that providing Albertans access to their health records will transform the delivery of healthcare in Alberta. It is important to have a high level of assurance that the health records are provided to the correct Albertan. Alberta Health requires a way for Albertans to obtain a digital identity with a high level of identity assurance prior to releasing health records via the Personal Health Portal. Service Alberta developed the MyAlberta Digital ID program to provide a digital identity verification service. The Ministry of Health is leveraging MyAlberta Digital ID to enable Albertans to access their personal health records through the Personal Health Portal. The Government of Alberta is advancing its vision of patient-centred healthcare by enabling Albertans to access a trusted source for health information and their electronic health records using a secure digital identity.

This qualitative study explored the cultural identity negotiation of young adult immigrants. Using a grounded theory research design, 10 semistructured interviews were conducted with emerging adult immigrants (EAI), ages 19-27. Results yielded a substantive model of cultural identity negotiation (MCIN) for EAI and posited that One's Motivation and Sense of Agency to Negotiate Cultural Identity is at the core of how participants navigate their cultural identities. This model included 6 major categories: (a) Family Cultural Rigidity ; (b) Connections Specific to Canada ; (c) Connection to a Same Cultured Community ; (d) Sense of Permanency ; (e) Desire to Preserve Culture of Origin ; (f) Desire to Fit in to Canadian Culture , as well as 2 overarching factors ( Dimension of Time and Dimension of Age ), which were found to be influential on participants' cultural identity negotiation. The model also included the identification of 4 approaches to cultural identity negotiation: (a) Blended; (b) Dual; (c) Disconnected; and (d) Intermediate. The MCIN for EAI is discussed in terms of the current literature on cultural identity formation as well as implications for counseling psychology training and practice. Recommendations for further research are also suggested. (PsycINFO Database Record (c) 2018 APA, all rights reserved).

Outside health care settings, people may acquire ESBL-producing bacteria through different exposure routes, including contact with human or animal carriers or consumption of contaminated food. However, contact with faecally contaminated surface water may also represent a possible exposure route. The current study investigated the prevalence and characteristics of ESBL-producing Escherichia coli in four Dutch recreational waters and the possible role of nearby waste water treatment plants (WWTP) as contamination source. Isolates from recreational waters were compared with isolates from WWTP effluents, from surface water upstream of the WWTPs, at WWTP discharge points, and in connecting water bodies not influenced by the studied WWTPs. ESBL-producing E. coli were detected in all four recreational waters, with an average concentration of 1.3 colony forming units/100ml, and in 62% of all samples. In surface waters not influenced by the studied WWTPs, ESBL-producing E. coli were detected in similar concentrations, indicating the existence of additional ESBL-E. coli contamination sources. Isolates with identical ESBL-genes, phylogenetic background, antibiotic resistance profiles, and sequence type, were obtained from effluent and different surface water sites in the same watershed, on the same day; occasionally this included isolates from recreational waters. Recreational waters were identified as a potential exposure source of ESBL-producing E. coli. WWTPs were shown to contribute to the presence of these bacteria in surface waters, but other (yet unidentified) sources likely co-contribute. Copyright © 2014 Elsevier B.V. All rights reserved.

cPath: open source software for collecting, storing, and querying biological pathways

Cerami, Ethan G; Bader, Gary D; Gross, Benjamin E; Sander, Chris

2006-01-01

Background Biological pathways, including metabolic pathways, protein interaction networks, signal transduction pathways, and gene regulatory networks, are currently represented in over 220 diverse databases. These data are crucial for the study of specific biological processes, including human diseases. Standard exchange formats for pathway information, such as BioPAX, CellML, SBML and PSI-MI, enable convenient collection of this data for biological research, but mechanisms for common storage and communication are required. Results We have developed cPath, an open source database and web application for collecting, storing, and querying biological pathway data. cPath makes it easy to aggregate custom pathway data sets available in standard exchange formats from multiple databases, present pathway data to biologists via a customizable web interface, and export pathway data via a web service to third-party software, such as Cytoscape, for visualization and analysis. cPath is software only, and does not include new pathway information. Key features include: a built-in identifier mapping service for linking identical interactors and linking to external resources; built-in support for PSI-MI and BioPAX standard pathway exchange formats; a web service interface for searching and retrieving pathway data sets; and thorough documentation. The cPath software is freely available under the LGPL open source license for academic and commercial use. Conclusion cPath is a robust, scalable, modular, professional-grade software platform for collecting, storing, and querying biological pathways. It can serve as the core data handling component in information systems for pathway visualization, analysis and modeling. PMID:17101041

Nurses' narratives of moral identity: Making a difference and reciprocal holding.

2018-05-01

Explicating nurses' moral identities is important given the powerful influence moral identity has on the capacity to exercise moral agency. The purpose of this study was to explore how nurses narrate their moral identity through their understanding of their work. An additional purpose was to understand how these moral identities are held in the social space that nurses occupy. The Registered Nurse Journal, a bimonthly publication of the Registered Nurses' Association of Ontario, Canada, features a regular column entitled, 'In the End … What Nursing Means to Me …' These short narratives generally include a story of an important moment in the careers of the authors that defined their identities as nurses. All 29 narratives published before June 2015 were analysed using a critical narrative approach, informed by the work of Margaret Urban Walker and Hilde Lindemann, to identify a typology of moral identity. Ethical considerations: Ethics approval was not required because the narratives are publicly available. Two narrative types were identified that represent the moral identities of nurses as expressed through their work: (1) making a difference in the lives of individuals and communities and (2) holding the identities of vulnerable individuals. Nurses' moral identities became evident when they could see improvement in the health of patients or communities or when they could maintain the identity of their patients despite the disruptive forces of illness and hospitalization. In reciprocal fashion, the responses of their patients, including expressions of gratitude, served to hold the moral identities of these nurses. Ultimately, the sustainability of nurses' moral identities may be dependent on the recognition of their own needs for professional satisfaction and care in ways that go beyond the kind of acknowledgement that patients can offer.

The processing of facial identity and expression is interactive, but dependent on task and experience

PubMed Central

Yankouskaya, Alla; Humphreys, Glyn W.; Rotshtein, Pia

2014-01-01

Facial identity and emotional expression are two important sources of information for daily social interaction. However the link between these two aspects of face processing has been the focus of an unresolved debate for the past three decades. Three views have been advocated: (1) separate and parallel processing of identity and emotional expression signals derived from faces; (2) asymmetric processing with the computation of emotion in faces depending on facial identity coding but not vice versa; and (3) integrated processing of facial identity and emotion. We present studies with healthy participants that primarily apply methods from mathematical psychology, formally testing the relations between the processing of facial identity and emotion. Specifically, we focused on the “Garner” paradigm, the composite face effect and the divided attention tasks. We further ask whether the architecture of face-related processes is fixed or flexible and whether (and how) it can be shaped by experience. We conclude that formal methods of testing the relations between processes show that the processing of facial identity and expressions interact, and hence are not fully independent. We further demonstrate that the architecture of the relations depends on experience; where experience leads to higher degree of inter-dependence in the processing of identity and expressions. We propose that this change occurs as integrative processes are more efficient than parallel. Finally, we argue that the dynamic aspects of face processing need to be incorporated into theories in this field. PMID:25452722

Information fusion: telling the story (or threat narrative)

Fenstermacher, Laurie

2014-06-01

Today's operators face a "double whammy" - the need to process increasing amounts of information, including "Twitter-INT"1 (social information such as Facebook, You-Tube videos, blogs, Twitter) as well as the need to discern threat signatures in new security environments, including those in which the airspace is contested. To do this will require the Air Force to "fuse and leverage its vast capabilities in new ways."2 For starters, the integration of quantitative and qualitative information must be done in a way that preserves important contextual information since the goal increasingly is to identify and mitigate violence before it occurs. To do so requires a more nuanced understanding of the environment being sensed, including the human environment, ideally from the "emic" perspective; that is, from the perspective of that individual or group. This requires not only data and information that informs the understanding of how the individuals and/or groups see themselves and others (social identity) but also information on how that identity filters information in their environment which, in turn, shapes their behaviors.3 The goal is to piece together the individual and/or collective narratives regarding threat, the threat narrative, from various sources of information. Is there a threat? If so, what is it? What is motivating the threat? What is the intent of those who pose the threat and what are their capabilities and their vulnerabilities?4 This paper will describe preliminary investigations regarding the application of prototype hybrid information fusion method based on the threat narrative framework.

Matching novel face and voice identity using static and dynamic facial images.

PubMed

Smith, Harriet M J; Dunn, Andrew K; Baguley, Thom; Stacey, Paula C

2016-04-01

Research investigating whether faces and voices share common source identity information has offered contradictory results. Accurate face-voice matching is consistently above chance when the facial stimuli are dynamic, but not when the facial stimuli are static. We tested whether procedural differences might help to account for the previous inconsistencies. In Experiment 1, participants completed a sequential two-alternative forced choice matching task. They either heard a voice and then saw two faces or saw a face and then heard two voices. Face-voice matching was above chance when the facial stimuli were dynamic and articulating, but not when they were static. In Experiment 2, we tested whether matching was more accurate when faces and voices were presented simultaneously. The participants saw two face-voice combinations, presented one after the other. They had to decide which combination was the same identity. As in Experiment 1, only dynamic face-voice matching was above chance. In Experiment 3, participants heard a voice and then saw two static faces presented simultaneously. With this procedure, static face-voice matching was above chance. The overall results, analyzed using multilevel modeling, showed that voices and dynamic articulating faces, as well as voices and static faces, share concordant source identity information. It seems, therefore, that above-chance static face-voice matching is sensitive to the experimental procedure employed. In addition, the inconsistencies in previous research might depend on the specific stimulus sets used; our multilevel modeling analyses show that some people look and sound more similar than others.

Building an Ontology for Identity Resolution in Healthcare and Public Health.

Integration of disparate information from electronic health records, clinical data warehouses, birth certificate registries and other public health information systems offers great potential for clinical care, public health practice, and research. Such integration, however, depends on correctly matching patient-specific records using demographic identifiers. Without standards for these identifiers, record linkage is complicated by issues of structural and semantic heterogeneity. Our objectives were to develop and validate an ontology to: 1) identify components of identity and events subsequent to birth that result in creation, change, or sharing of identity information; 2) develop an ontology to facilitate data integration from multiple healthcare and public health sources; and 3) validate the ontology's ability to model identity-changing events over time. We interviewed domain experts in area hospitals and public health programs and developed process models describing the creation and transmission of identity information among various organizations for activities subsequent to a birth event. We searched for existing relevant ontologies. We validated the content of our ontology with simulated identity information conforming to scenarios identified in our process models. We chose the Simple Event Model (SEM) to describe events in early childhood and integrated the Clinical Element Model (CEM) for demographic information. We demonstrated the ability of the combined SEM-CEM ontology to model identity events over time. The use of an ontology can overcome issues of semantic and syntactic heterogeneity to facilitate record linkage.

Concealable Stigmatized Identities and Psychological Well-Being

PubMed Central

Quinn, Diane M.; Earnshaw, Valerie A.

2013-01-01

Many people have concealable stigmatized identities: Identities that can be hidden from others and that are socially devalued and negatively stereotyped. Understanding how these concealable stigmatized identities affect psychological well-being is critical. We present our model of the components of concealable stigmatized identities including valenced content – internalized stigma, experienced discrimination, anticipated stigma, disclosure reactions, and counter-stereotypic/positive information – and magnitude – centrality and salience. Research has shown that negatively valenced content is related to increased psychological distress. However, smaller identity magnitude may buffer this distress. We review the research available and discuss important areas for future work. PMID:23730326

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

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

Design of two blackbody sources for millimeter and sub-millimeter wave Fourier transform spectrometry

NASA Astrophysics Data System (ADS)

Colin, Angel

2014-03-01

This paper describes an experimental setup for the spectral calibration of bolometric detectors used in radioastronomy. The system is composed of a Martin-Puplett interferometer with two identical artificial blackbody sources operating in the vacuum mode at 77 K and 300 K simultaneously. One source is integrated into a liquid nitrogen cryostat, and the other one into a vacuum chamber at room temperature. The sources were designed with a combination of conical with cylindrical geometries thus forming an orthogonal configuration to match the internal optics of the interfermometer. With a simple mathematical model we estimated emissivities of ε 0.995 for each source.

Visible signs of illness from the 14th to the 20th century: systematic review of portraits

Objectives To see whether a collection of portraits depicting inhabitants of a defined geographical region and covering several centuries is a useful source for studying the sociocultural significance and epidemiology of particular visible diseases, such as goitre, which is known to have been common in this region. Design Systematic review of portraits and description of visible signs of illness. Setting The Burgerbibliothek (archives of the burghers' community) in Berne, Switzerland. Data sources 3615 portraits; 2989 of individuals whose identity is known and 626 of individuals whose identity is unknown. Main outcome measures Visible signs of illness evaluated by means of a standardised visual assessment. Results Visible signs of illness in portraits were common and appeared in up to 82% (451/553) of paintings from the 17th and 18th centuries. The most common findings were signs of goitre in women and overweight in men. In only the portraits where the neck region could be evaluated, 41% of women with known identities (139/343) had goitre compared with 24% of men with known identities (21/86). The prevalence of goitre was even higher in sitters whose identities were unknown: 63% in men (5/8) and 68% in women (82/121). Overweight in people with known identities was more common in men than in women (30%, 346/1145 v 44%, 811/1844). Overweight was most common in sitters aged >40 than in those aged 40 or younger. Other conditions, such as missing teeth, amputated limbs, or osteoarthritic deformations were surprisingly rare in the portraits under evaluation. Conclusions Goitre and other diseases are under-represented in the people depicted in these portraits. Artistic idealisation is a likely explanation for this observation: what was reproduced depended on what was considered pathological or shameful at the time, and therefore depended on age and sex. Stigmatising details may have been omitted. Further, artistic skills and contemporary fashion may have influenced the way in which people were reproduced. People depicted are possibly not representative of the general Bernese population as they constituted a socioeconomically advantaged group. What is already know on this topicReviews of individual portraits from the past have found clinical signs of illness that have led to discussions of underlying diseasesGoitre probably affected in excess of 80% of the population of the canton of Berne up to the beginning of the 20th centuryWhat this study addsIn a large series of portraits from the Bernese region, goitre and other diseases are under-representedFindings of age dependent overweight (a survival advantage in times of potential famine) were probably more realisticLikely explanations for this include idealisation depending on sex and age, artistic skills, fashion, and sociocultural significance of illnessA decline in depicted signs of illness from the 19th century may indicate progress of preventive medicine and hygiene PMID:12493682

From induction to conduction: how intrinsic transcriptional priming of extrinsic neuronal connectivity shapes neuronal identity.

PubMed

Russ, Jeffrey B; Kaltschmidt, Julia A

2014-10-01

Every behaviour of an organism relies on an intricate and vastly diverse network of neurons whose identity and connectivity must be specified with extreme precision during development. Intrinsically, specification of neuronal identity depends heavily on the expression of powerful transcription factors that direct numerous features of neuronal identity, including especially properties of neuronal connectivity, such as dendritic morphology, axonal targeting or synaptic specificity, ultimately priming the neuron for incorporation into emerging circuitry. As the neuron's early connectivity is established, extrinsic signals from its pre- and postsynaptic partners feedback on the neuron to further refine its unique characteristics. As a result, disruption of one component of the circuitry during development can have vital consequences for the proper identity specification of its synaptic partners. Recent studies have begun to harness the power of various transcription factors that control neuronal cell fate, including those that specify a neuron's subtype-specific identity, seeking insight for future therapeutic strategies that aim to reconstitute damaged circuitry through neuronal reprogramming.

The threatened self: Considerations of time, place, and uncertainty in advanced illness.

Nanton, Veronica; Munday, Dan; Dale, Jeremy; Mason, Bruce; Kendall, Marilyn; Murray, Scott

2016-05-01

Loss of self and the transition to patient-hood have been widely discussed in relation to the experience of advanced illness. Individuals however often maintain identities or selves beyond those demanded by the circumstances of being a patient. This study explores the presentation of this personal identity and interactions between intrinsic and extrinsic elements that support or threaten its maintenance. In particular, this study examined the impact of uncertainty on the representations of self and the part played by the patient's health care professionals and the systems in which they are embedded, in limiting or reinforcing its effects. Complementary methods of ethnographic observation and serial narrative interviews were adopted to explore both the lo"cal social and health care context and the changing presentation of self by patients with advanced multimorbidity, chronic illness, and cancer. In total, 36 interviews were undertaken with 16 patients. Analysis was guided by concepts of time and place, combining contextual data with the unfolding patient narrative. Good pain and symptom control was a necessary, but not sufficient, condition for the maintenance of a personal identity. Essential agentic elements included knowledge of appropriate and immediate sources of help. Also important were a sense of control achieved through a shared understanding with health care professionals of the condition and active management of uncertainty. In addition, the maintenance of self depended on keeping a connection with aspects of life associated with a pre-illness identity. Critically, this self was contingent on external recognition, acknowledgement, and validation. Professional relationships that focus solely on the 'person as patient' may be insufficient for patients' needs. Health care professionals should seek to recognize and acknowledge the personal identity that may be critical to their sense of self-worth. Through an ongoing relationship guiding the patient through the uncertainties they face, health care professionals may play an essential role in sustaining the 'patient as person'. What is already known on this subject? Loss of self or personal identity occurs in a range of serious conditions. The sick self is incorporated in a process of identity reconstruction. Uncertainty is an inherent aspect of serious and advanced illness. Unmanaged uncertainty results in a range of negative psychological consequences that contribute to the loss of personal identity. Information and communication with health care professionals help patients manage uncertainty. What does this study add? Sufferers may retain a personal identity continuous with a pre-illness self using internal and external resources. The pre-illness self may be subsumed by the patient self especially at times of transition and maximum uncertainty. Acknowledgement and facilitation by health care professionals can enable the preservation of the pre-illness self. © 2015 The British Psychological Society.

Restrictive loads powered by separate or by common electrical sources

Appelbaum, J.

1989-01-01

In designing a multiple load electrical system, the designer may wish to compare the performance of two setups: a common electrical source powering all loads, or separate electrical sources powering individual loads. Three types of electrical sources: an ideal voltage source, an ideal current source, and solar cell source powering resistive loads were analyzed for their performances in separate and common source systems. A mathematical proof is given, for each case, indicating the merit of the separate or common source system. The main conclusions are: (1) identical resistive loads powered by ideal voltage sources perform the same in both system setups, (2) nonidentical resistive loads powered by ideal voltage sources perform the same in both system setups, (3) nonidentical resistive loads powered by ideal current sources have higher performance in separate source systems, and (4) nonidentical resistive loads powered by solar cells have higher performance in a common source system for a wide range of load resistances.

The production of consuming less: Energy efficiency, climate change, and light bulbs in North Carolina

NASA Astrophysics Data System (ADS)

Thoyre, Autumn

In this research, I have analyzed the production of consuming less electricity through a case study of promotions of compact fluorescent light bulbs (CFLs). I focused on the CFL because it has been heavily promoted by environmentalists and electricity companies as a key tool for solving climate change, yet such promotions appear counter-intuitive. The magnitude of CFL promotions by environmentalists is surprising because CFLs can only impact less than 1% of U.S. greenhouse gas emissions. CFL promotions by electricity providers are surprising given such companies' normal incentives to sell more of their product. I used political ecological and symbolic interactionist theories, qualitative methods of data collection (including interviews, participant-observation, texts, and images), and a grounded theory analysis to understand this case. My findings suggest that, far from being a self-evident technical entity, energy efficiency is produced as an idea, a part of identities, a resource, and a source of value through social, political, and economic processes. These processes include identity formation and subjectification; gender-coded household labor; and corporate appropriation of household value resulting from environmental governance. I show how environmentalists use CFLs to make and claim neoliberal identities, proposing the concept of green neoliberal identity work as a mechanism through which neoliberal ideologies are translated into practices. I analyze how using this seemingly easy energy efficient technology constitutes labor that is gendered in ways that reflect and reproduce inequalities. I show how electricity companies have used environmental governance to valorize and appropriate home energy efficiency as an accumulation strategy. I conclude by discussing the symbolic power of CFLs, proposing a theory of green obsolescence, and framing the production of energy efficiency as a global production network. I found that promoting energy efficiency involves consuming less energy by consuming more technologies. This research contributes to understandings of how environmentalists become laboring subjects in an era of neoliberalism and how energy companies are responding to the threat of climate change by turning mitigation into an opportunity for profit.

Social Identities in a Globalized World: Challenges and Opportunities for Collective Action.

PubMed

Rosenmann, Amir; Reese, Gerhard; Cameron, James E

2016-03-01

Globalization-the increasing interconnectedness of societies, economies, and cultures-is a defining feature of contemporary social life. Paradoxically, it underlies both the dynamics of global crises (e.g., rising inequality, climate change) and the possibilities for ameliorating them. In this review, we introduce globalization as a multifaceted process and elaborate its psychological effects with respect to identity, culture, and collective action. Using a social identity approach, we discuss three foci of identification: local culture, globalized Western culture, and humanity in its entirety. Each source of identification is analyzed in terms of its psychological meaning and position vis-à-vis the global power structure. Globalized Western culture forms the basis for an exclusive globalized identity, which privileges only some cultures and ways of life. We conceptualize reactions to its core values in terms of cultural identification and rejection and acceptance of, or opposition to, its global social order. Opposition to this inequitable global order is central to inclusive globalized identities (e.g., identification with humanity). These identities may encourage globally minded collective action, even as more research is needed to address their potential caveats. We consider possibilities for social change and action and conclude that a focused application of psychological science to the study of these issues is overdue. © The Author(s) 2016.

Benzoate-mediated changes on expression profile of soluble proteins in Serratia sp. DS001.

Pandeeti, E V P; Chinnaboina, M R; Siddavattam, D

2009-05-01

To assess differences in protein expression profile associated with shift in carbon source from succinate to benzoate in Serratia sp. DS001 using a proteomics approach. A basic proteome map was generated for the soluble proteins extracted from Serratia sp. DS001 grown in succinate and benzoate. The differently and differentially expressed proteins were identified using ImageMaster 2D Platinum software (GE Healthcare). The identity of the proteins was determined by employing MS or MS/MS. Important enzymes such as Catechol 1,2 dioxygenase and transcriptional regulators that belong to the LysR superfamily were identified. Nearly 70 proteins were found to be differentially expressed when benzoate was used as carbon source. Based on the protein identity and degradation products generated from benzoate it is found that ortho pathway is operational in Serratia sp. DS001. Expression profile of the soluble proteins associated with shift in carbon source was mapped. The study also elucidates degradation pathway of benzoate in Serratia sp. DS001 by correlating the proteomics data with the catabolites of benzoate.

A systematic literature review of engineering identity: definitions, factors, and interventions affecting development, and means of measurement

NASA Astrophysics Data System (ADS)

Morelock, John R.

2017-11-01

Studies exploring what it means to be an engineer professionally have been conducted for decades, but have boomed in recent years. This systematic literature review aims to organise extant studies on engineering identity by coding around four key variables: (a) definitions of engineering identity, (b) factors affecting engineering identity development, (c) interventions affecting engineering identity development, and (d) means of measuring identity. In doing so, this review provides strategies for future research and educational interventions to advance work related to engineering identity. Publications were selected for inclusion by screening and appraising results obtained from databases and keywords refined through a scoping study. Derived from key findings, suggestions for future research include bridging disparate strands of engineering identity literature and incorporating more varied methodological approaches. Also from key findings, suggestions for future practice involve better connecting existing definitions of engineering identity and factors known to affect identity development with identity-related interventions.

Lee, Debbiesiu L; Ahn, Soyeon

2013-01-01

This meta-analysis synthesized the results of 27 studies examining the relations of racial identity, ethnic identity, and racial socialization to discrimination-distress for Black Americans. The purpose was to uncover which constructs connected to racial identity, ethnic identity, and racial socialization most strongly correlate with racial discrimination and psychological distress. Discrimination significantly related to aspects of racial identity, including immersion-emersion, public regard, encounter, Afrocentricity/racial centrality/private regard, and internalization. Distress significantly correlated with preencounter/assimilation, encounter, public regard, immersion-emersion, and Afrocentricity/racial centrality/private regard. Several of these relationships were significantly moderated by the measure of racial identity or demographic variables (gender or age). Implications of these findings are discussed.

Self-calibration of Cosmic Microwave Background Polarization Experiments

NASA Astrophysics Data System (ADS)

Keating, Brian G.; Shimon, Meir; Yadav, Amit P. S.

2013-01-01

Precision measurements of the polarization of the cosmic microwave background (CMB) radiation, especially experiments seeking to detect the odd-parity "B-modes," have far-reaching implications for cosmology. To detect the B-modes generated during inflation, the flux response and polarization angle of these experiments must be calibrated to exquisite precision. While suitable flux calibration sources abound, polarization angle calibrators are deficient in many respects. Man-made polarized sources are often not located in the antenna's far-field, have spectral properties that are radically different from the CMB's, are cumbersome to implement, and may be inherently unstable over the (long) duration these searches require to detect the faint signature of the inflationary epoch. Astrophysical sources suffer from time, frequency, and spatial variability, are not visible from all CMB observatories, and none are understood with sufficient accuracy to calibrate future CMB polarimeters seeking to probe inflationary energy scales of 1015 GeV. Both man-made and astrophysical sources require dedicated observations which detract from the amount of integration time usable for detection of the inflationary B-modes. CMB TB and EB modes, expected to identically vanish in the standard cosmological model, can be used to calibrate CMB polarimeters. By enforcing the observed EB and TB power spectra to be consistent with zero, CMB polarimeters can be calibrated to levels not possible with man-made or astrophysical sources. All of this can be accomplished for any polarimeter without any loss of observing time using a calibration source which is spectrally identical to the CMB B-modes.

Selected Theoretical Studies Group contributions to the 14th International Cosmic Ray conference. [including studies on galactic molecular hydrogen, interstellar reddening, and on the origin of cosmic rays

1975-01-01

The galactic distribution of H2 was studied through gamma radiation and through X-ray, optical, and infrared absorption measurements from SAS-2 and other sources. A comparison of the latitude distribution of gamma-ray intensity with reddening data shows reddening data to give the best estimate of interstellar gas in the solar vicinity. The distribution of galactic cosmic ray nucleons was determined and appears to be identical to the supernova remnant distribution. Interactions between ultrahigh energy cosmic-ray nuclei and intergalactic photon radiation fields were calculated, using the Monte Carlo method.

Targeting and tailoring message-framing: the moderating effect of racial identity on receptivity to colorectal cancer screening among African-Americans.

PubMed

Lucas, Todd; Manning, Mark; Hayman, Lenwood W; Blessman, James

2018-06-07

This study demonstrates the potential of racial identity to moderate how gain and loss-framed messaging, as well as culturally-targeted messaging, can affect receptivity to preventive health screening. African-Americans (N = 132) who were noncompliant with recommended colorectal cancer (CRC) screening completed a measure of racial identity centrality-encompassing the extent to which racial identity is a core component of self-concept-and then participated in an online education module about CRC screening, during which either gain or loss-framed messaging was introduced. Half of African-Americans were also exposed to a culturally-targeted self-help message about preventing CRC. Theory of Planned Behavior measures of attitudes, normative beliefs, perceived behavioral control, and intentions to obtain a CRC screen served as outcomes. Results confirmed that effects of messaging on receptivity to CRC screening depended on racial identity. Among low racial identity African Americans, gain-framed messaging most effectively increased normative beliefs about obtaining CRC screening, whereas among high racial identity African Americans loss-framed messaging was most compelling. However, these effects most strongly emerged when culturally-targeted self-help messaging was included. We discuss implications for health disparities theory and research, including a potential to simultaneously deploy culturally-targeted and tailored messaging based on racial identity.

Self-Calibration of CMB Polarimeters

Reliability of MEG source imaging of anterior temporal spikes: analysis of an intracranially characterized spike focus.

PubMed

Wennberg, Richard; Cheyne, Douglas

2014-05-01

To assess the reliability of MEG source imaging (MSI) of anterior temporal spikes through detailed analysis of the localization and orientation of source solutions obtained for a large number of spikes that were separately confirmed by intracranial EEG to be focally generated within a single, well-characterized spike focus. MSI was performed on 64 identical right anterior temporal spikes from an anterolateral temporal neocortical spike focus. The effects of different volume conductors (sphere and realistic head model), removal of noise with low frequency filters (LFFs) and averaging multiple spikes were assessed in terms of the reliability of the source solutions. MSI of single spikes resulted in scattered dipole source solutions that showed reasonable reliability for localization at the lobar level, but only for solutions with a goodness-of-fit exceeding 80% using a LFF of 3 Hz. Reliability at a finer level of intralobar localization was limited. Spike averaging significantly improved the reliability of source solutions and averaging 8 or more spikes reduced dependency on goodness-of-fit and data filtering. MSI performed on topographically identical individual spikes from an intracranially defined classical anterior temporal lobe spike focus was limited by low reliability (i.e., scattered source solutions) in terms of fine, sublobar localization within the ipsilateral temporal lobe. Spike averaging significantly improved reliability. MSI performed on individual anterior temporal spikes is limited by low reliability. Reduction of background noise through spike averaging significantly improves the reliability of MSI solutions. Copyright © 2013 International Federation of Clinical Neurophysiology.

X-Ray Spectro-Polarimetry with Photoelectric Polarimeters

NASA Technical Reports Server (NTRS)

Strohmayer, T. E.

2017-01-01

We derive a generalization of forward fitting for X-ray spectroscopy to include linear polarization of X-ray sources, appropriate for the anticipated next generation of space-based photoelectric polarimeters. We show that the inclusion of polarization sensitivity requires joint fitting to three observed spectra, one for each of the Stokes parameters, I(E), U(E), and Q(E). The equations for StokesI (E) (the total intensity spectrum) are identical to the familiar case with no polarization sensitivity, and for which the model-predicted spectrum is obtained by a convolution of the source spectrum, F (E), with the familiar energy response function,(E) R(E,E), where (E) and R(E,E) are the effective area and energy redistribution matrix, respectively. In addition to the energy spectrum, the two new relations for U(E) and Q(E) include the source polarization fraction and position angle versus energy, a(E), and 0(E), respectively, and the model-predicted spectra for these relations are obtained by a convolution with the modulated energy response function, (E)(E) R(E,E), where(E) is the energy-dependent modulation fraction that quantifies a polarimeters angular response to 100 polarized radiation. We present results of simulations with response parameters appropriate for the proposed PRAXyS Small Explorer observatory to illustrate the procedures and methods, and we discuss some aspects of photoelectric polarimeters with relevance to understanding their calibration and operation.

Vegetarianism, dietary restraint and feminist identity.

PubMed

Curtis, Morgan J; Comer, Lisa K

2006-05-01

Research examining the relationship between dietary restraint and vegetarianism has yielded inconsistent results due to differing definitions of vegetarianism and the possible modifying role of feminist identity. The current study sought to further clarify these relationships by examining three levels of vegetarianism, motivation for vegetarianism, and feminist identity (using an updated measure). Participants were 90 female undergraduate students and community members (mean age=24.34 years). Dietary restraint was measured using the TFEQ; feminism was assessed using the LFAIS. Weight-motivated semi-vegetarians reported higher levels of dietary restraint than those not motivated by weight. This effect did not appear among full-vegetarians. Lowest levels of dietary restraint were found among full-vegetarians with no difference between non- and semi-vegetarians. Contrary to previous research, feminist identity did not moderate the relationship between dietary restraint and vegetarianism. Limitations resulting from a scale with a narrow definition of feminism and the use of multiple sources of recruitment are discussed. Directions for future research are highlighted.

Gender identity: a multidimensional analysis with implications for psychosocial adjustment.

PubMed

Egan, S K; Perry, D G

2001-07-01

This study examined the relations between components of gender identity and psychosocial adjustment. The aspects of gender identity assessed were (a) feelings of psychological compatibility with one's gender (i.e.. feeling one is a typical member of one's sex and feeling content with one's biological sex), (b) feelings of pressure from parents, peers, and self for conformity to gender stereotypes. and (c) the sentiment that one's own sex is superior to the other (intergroup bias). Adjustment was assessed in terms of self-esteem and peer acceptance. Participants were 182 children in Grades 4 through 8. Felt gender compatibility (when operationalized as either self-perceived gender typicality or feelings of contentment with one's biological sex) was positively related to adjustment, whereas felt pressure and intergroup bias were negatively associated with adjustment. The results provide new insights into the role of gender identity in children's well-being, help identify sources of confusion in previous work, and suggest directions for future inquiry.

Becoming an engineer: Doctoral women's perspectives on identity and learning in the culture of engineering

NASA Astrophysics Data System (ADS)

Wood, Shaunda L.

Women face many obstacles in their academic careers but there is a gap in the research with regards to their perceptions of science and engineering education and how non/participation in the culture of engineering affects their identities. Moreover, little research has been conducted with female Ph.D. students especially with regard to the reasons they have continued their studies, and their level of satisfaction with their career and lives. This study was guided by the sociocultural approach and theories of learning and identity. Methodologically, the design adopted is a naturalistic qualitative inquiry using two open-ended interviews with participant verification after the first interview. The life history narratives (Mishler, 1999) obtained from the seven doctoral electrical and mechanical women engineers, at various stages in their programs, were the primary source of data. By examining the path of becoming a doctoral woman engineer, this study makes the educational experiences of women intelligible to the general public as well as policy makers. It gives voice to the women engineers whose perspectives are rarely heard in academic settings or mainstream society. The findings of the study lend insight to the importance and necessity of more inclusive engineering education, incorporating not only women's studies courses into the curriculum but anti-racism education as well as including the perspective of 'Other' people of difference. Moreover, multi-perspective approaches to increasing enrolment and retention of women in engineering were more effective and in keeping with addressing notions of 'difference' in engineering populations.

Multispectral glancing incidence X-ray telescope

A multispectral glancing incidence X-ray telescope is illustrated capable of broadband, high-resolution imaging of solar and stellar X-ray and extreme ultraviolet radiation sources which includes a primary optical system preferably of the Wolter I type having a primary mirror system (20, 22). The primary optical system further includes an optical axis (24) having a primary focus (F1) at which the incoming radiation is focused by the primary mirrors. A plurality of ellipsoidal mirrors (30a, 30b, 30cand 30d) are carried at an inclination to the optical axis behind the primary focus (F1). A rotating carrier (32) is provided on which the ellipsoidal mirrors are carried so that a desired one of the ellipsoidal mirrors may be selectively positioned in front of the incoming radiation beam (26). In the preferred embodiment, each of the ellipsoidal mirrors has an identical concave surface carrying a layered synthetic microstructure coating tailored to reflect a desired wavelength of 1.5 .ANG. or longer. Each of the identical ellipsoidal mirrors has a second focus (F2) at which a detector (16) is carried. Thus the different wavelength image is focused upon the detector irregardless of which mirror is positioned in front of the radiation beam. In this manner, a plurality of low wavelengths in a wavelength band generally less than 30 angstroms can be imaged with a high resolution.

Source preference and ambiguity aversion: models and evidence from behavioral and neuroimaging experiments.

PubMed

Chew, Soo Hong; Li, King King; Chark, Robin; Zhong, Songfa

2008-01-01

This experimental economics study using brain imaging techniques investigates the risk-ambiguity distinction in relation to the source preference hypothesis (Fox & Tversky, 1995) in which identically distributed risks arising from different sources of uncertainty may engender distinct preferences for the same decision maker, contrary to classical economic thinking. The use of brain imaging enables sharper testing of the implications of different models of decision-making including Chew and Sagi's (2008) axiomatization of source preference. Using fMRI, brain activations were observed when subjects make 48 sequential binary choices among even-chance lotteries based on whether the trailing digits of a number of stock prices at market closing would be odd or even. Subsequently, subjects rate familiarity of the stock symbols. When contrasting brain activation from more familiar sources with those from less familiar ones, regions appearing to be more active include the putamen, medial frontal cortex, and superior temporal gyrus. ROI analysis showed that the activation patterns in the familiar-unfamiliar and unfamiliar-familiar contrasts are similar to those in the risk-ambiguity and ambiguity-risk contrasts reported by Hsu et al. (2005). This supports the conjecture that the risk-ambiguity distinction can be subsumed by the source preference hypothesis. Our odd-even design has the advantage of inducing the same "unambiguous" probability of half for each subject in each binary comparison. Our finding supports the implications of the Chew-Sagi model and rejects models based on global probabilistic sophistication, including rank-dependent models derived from non-additive probabilities, e.g., Choquet expected utility and cumulative prospect theory, as well as those based on multiple priors, e.g., alpha-maxmin. The finding in Hsu et al. (2005) that orbitofrontal cortex lesion patients display neither ambiguity aversion nor risk aversion offers further support to the Chew-Sagi model. Our finding also supports the Levy et al. (2007) contention of a single valuation system encompassing risk and ambiguity aversion. This is the first neuroimaging study of the source preference hypothesis using a design which can discriminate among decision models ranging from risk-based ones to those relying on multiple priors.

Negotiating homosexual identities: the experiences of men who have sex with men in Guangzhou.

PubMed

Li, Haochu Howard; Holroyd, Eleanor; Lau, Joseph T F

2010-05-01

This paper reports on an ethnographic study of male homosexuality in contemporary Chinese society. The study focused on how men negotiated with the mainstream Chinese heterosexual society and in so doing constructed their sexual identities. The factors found to inform sexual identity were: the cultural imperative of heterosexual marriage, normative family obligations, desired gender roles, emotional experiences and a need for social belonging. The four types of sexual identities constructed included: establishing a deliberate non-homosexual identity, accumulating an individual homosexual identity, forming a collective homosexual identity and adopting a flexible sexual identity. For the men interviewed, sexual identity was both fluid and fragmented, derived from highly personalised negotiations between individualised needs and social and cultural constructs. The analysis is set against the background of China's rapid and recent economic development, shifting national and international social environments and improved access to the Internet.

Sport-Related Identities and the "Toxic Jock"

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.

Localization of short-range acoustic and seismic wideband sources: Algorithms and experiments

NASA Astrophysics Data System (ADS)

Stafsudd, J. Z.; Asgari, S.; Hudson, R.; Yao, K.; Taciroglu, E.

2008-04-01

We consider the determination of the location (source localization) of a disturbance source which emits acoustic and/or seismic signals. We devise an enhanced approximate maximum-likelihood (AML) algorithm to process data collected at acoustic sensors (microphones) belonging to an array of, non-collocated but otherwise identical, sensors. The approximate maximum-likelihood algorithm exploits the time-delay-of-arrival of acoustic signals at different sensors, and yields the source location. For processing the seismic signals, we investigate two distinct algorithms, both of which process data collected at a single measurement station comprising a triaxial accelerometer, to determine direction-of-arrival. The direction-of-arrivals determined at each sensor station are then combined using a weighted least-squares approach for source localization. The first of the direction-of-arrival estimation algorithms is based on the spectral decomposition of the covariance matrix, while the second is based on surface wave analysis. Both of the seismic source localization algorithms have their roots in seismology; and covariance matrix analysis had been successfully employed in applications where the source and the sensors (array) are typically separated by planetary distances (i.e., hundreds to thousands of kilometers). Here, we focus on very-short distances (e.g., less than one hundred meters) instead, with an outlook to applications in multi-modal surveillance, including target detection, tracking, and zone intrusion. We demonstrate the utility of the aforementioned algorithms through a series of open-field tests wherein we successfully localize wideband acoustic and/or seismic sources. We also investigate a basic strategy for fusion of results yielded by acoustic and seismic arrays.

The importance of social identities in the management of and recovery from 'Diabulimia': A qualitative exploration.

PubMed

Hastings, Amy; McNamara, Niamh; Allan, Jacqueline; Marriott, Mike

2016-12-01

A significant barrier to recovery for individuals with co-morbid eating disorders and type 1 diabetes is the way in which group members self-categorise. Nonetheless, identity issues are neglected during the recovery process. The aim of this paper is to explore how group memberships (and the associated identities) both contribute to and hinder recovery in this cohort. Transcripts from five online focus groups with 13 members of an online support group for individuals with 'Diabulimia' were thematically analysed. Findings suggested that those with whom one shares a recovery identity can be well placed to provide psychological resources necessary for successful recovery although such connections can be damaging if group norms are not managed. Members recognised that other important relationships (including family and friends and health professionals) are also key to recovery; these other group memberships (and the associated identities) can be facilitated through the recovery identity group membership, which allows for external validation of the recovery identity, provides encouragement to disclose the illness to supportive others, and provides information to facilitate positive service interactions. While clinical interventions typically focus on eliminating disordered behaviours, we suggest that these should also include strengthening important group memberships that promote recovery.

Achievement of a positive ethnic identity has been linked to positive outcomes for ethnic minority youth and is fostered by parental ethnic socialization practices. In light of findings of variability in developmental trajectories and outcomes, we examined ethnic group variations in parents' ethnic socialization practices and adolescents' ethnic identity. Within a sample of 370 adolescents who self-identified as White, African American, Latino/a, or Asian American, and their parents, parental ethnic socialization practices (including preparation for bias, promotion of mistrust, and cultural socialization) and adolescent ethnic identity development (including identity exploration and commitment) were assessed at 10th and 11th grades. Consistent with predictions, African American youth reported higher levels of ethnic identity exploration and commitment than youth from other ethnic groups, and parents of African American youth tended to report higher levels of ethnic socialization than other parents. Parental cultural socialization significantly predicted adolescent ethnic identity exploration and commitment 1 year later; ethnicity did not moderate this link. Findings are discussed in the context of the schools and urban community from which the sample was recruited, highlighting the importance of sociocultural context in development.

While cigarette smoking is decreasing among young adults, rates of nicotine consumption through other devices, most notably electronic cigarettes, are on the rise. Framed by communication theory of identity, this study examines young adult smokers' experiences with relational others in regard to their smoking. Focus group discussions and individual interviews convened with 20 young adult cigarette and electronic cigarette smokers revealed identity gaps implicating the relational layer of identity, including personal-relational, enacted-relational, and personal-enacted-relational identity gaps. Participants used communicative and behavioral strategies to manage relational discrepancies. The documented identity gaps and management strategies present opportunities for targeted smoking cessation interventions that amplify dissonance created through identity gaps as a motivational tactic.

Research on the "dark side" of organizational behavior has determined that employee sabotage is most often a reaction by disgruntled employees to perceived mistreatment. To date, however, most studies on employee retaliation have focused on intra-organizational sources of (in)justice. Results from this field study of customer service representatives (N = 358) showed that interpersonal injustice from customers relates positively to customer-directed sabotage over and above intra-organizational sources of fairness. Moreover, the association between unjust treatment and sabotage was moderated by 2 dimensions of moral identity (symbolization and internalization) in the form of a 3-way interaction. The relationship between injustice and sabotage was more pronounced for employees high (vs. low) in symbolization, but this moderation effect was weaker among employees who were high (vs. low) in internalization. Last, employee sabotage was negatively related to job performance ratings.

For traditional coherent effects, two separated identical point sources can be interfered with each other only when the optical path difference is integer number of wavelengths, leading to alternate dark and bright fringes for different optical path difference. For hundreds of years, such a perfect coherent condition seems insurmountable. However, in this paper, based on transformation optics, two separated in-phase identical point sources can induce perfect interference with each other without satisfying the traditional coherent condition. This shifting illusion media is realized by inductor-capacitor transmission line network. Theoretical analysis, numerical simulations and experimental results are performed to confirm such a kind of perfect coherent effect and it is found that the total radiation power of multiple elements system can be greatly enhanced. Our investigation may be applicable to National Ignition Facility (NIF), Inertial Confined Fusion (ICF) of China, LED lighting technology, terahertz communication, and so on.

A capillary electrophoresis system comprises capillaries positioned in parallel to each other forming a plane. The capillaries are configured to allow samples to migrate. A light source is configured to illuminate the capillaries and the samples therein. This causes the samples to emit light. A lens is configured to receive the light emitted by the samples and positioned directly over a first group of the capillaries and obliquely over a second group of the capillaries. The light source is further configured to illuminate the second group of capillaries more than the first group of the capillaries such that amount of light received by the lens from the first group of capillaries is substantially identical to amount of light received from the second group of capillaries when an identical amount of the samples is migrating through the first and second group capillaries.

An examination of environmental collective identity development across three life-stages: The contribution of social public experiences at zoos

NASA Astrophysics Data System (ADS)

Fraser, John Robert

This research breaks ground toward a revised theory of how collective environmental identity is associated with pro-environmental behaviors. My research comprises three activities that examined the experiences of three groups of people who claim zoo visiting as an important part of their life-story. The three studied groups were; conservation biologists who describe zoo experiences as having significant formative role in their childhood development of environmental values; parents who prioritize zoo visits as an important cultural experiences for their children; and a active zoo volunteers. This research also investigated whether the group experiences these participants had at zoos contributed to the value these people place on their current collective and environmental identities. Field conservationists' interest in learning from animals was validated by parents who also valued education and helped these children develop identities that included other animals in their scope of justice. Parents used zoos instrumentally to promote caring for others as a skill that will serve their children's socio-political future as part of human society. In both cases, these experiences appeared to be shaped around developing attitudes that would include animals in these children's scope of justice in later life. Zoo volunteers included animals in their scope of justice, believing that other species were also important sources of for their knowledge development. Shared positive attitudes toward animals were central to volunteers feeling part of a community and contributing to their collective self-esteem. The group may serve a restorative function in their lives, allowing them to take on a more activist role in society, seeking to promote social norms that are more inclusive of animal rights, and helping them to change their behaviors toward more environmentally responsible ends. This research contributes to the understanding of the theory of planned behavior and the values/beliefs/norms theory by demonstrating that pro-environmental behavior may originate with parenting activities in out-of-home cultural institutions like zoos, and is associated with involvement in social groups at later points in the life-course. It demonstrates that sharing a collective identity like that of a zoo volunteer is associated with engaging in pro-environmental behaviors even before those beliefs and values are fully understood. Although the contribution of parenting and group activity to pro-environmental behaviors demonstrated in this research was small, these results do suggest that focusing on out-of-home support for parents teaching social skills through animal based experiences, and support of activities that promote group attachment for environmentally concerned citizens, may be a possible strategies to advance more environmentally responsible behavior in society for both the short and long term.

Resolution of rare earth element interferences in fossil energy by-product samples using sector-field ICP-MS

Here, the supply and price of rare earth elements (REEs) have become a concern to many countries in the world, which has led to renewed interest in exploration and recovery of REEs from secondary or waste sources. Potential high REE waste sources that are of particular interest are coal mining, preparation, combustion, and other fossil energy by-products, including those from natural gas production. In this work, we have examined a set of five solid samples from the treatment of produced and flowback water containing elevated concentrations of barium. In order to confirm the correct concentrations of Eu, we studied thesemore » materials using sector field inductively coupled plasma mass spectrometry (SF-ICP-MS), which is capable of resolving species of nearly identical masses, including Eu and BaO. While the use of quadrupole inductively coupled plasma mass spectrometry (Q-ICP-MS) for the REE analysis of most geological sample matrices should pose no problem, the presence of large amounts of Ba, as encountered in water treatment solids from natural gas produced and flowback samples may require SF-ICP-MS for accurate determination of all REEs.« less

As collaborative science spreads into more and more Earth and space science fields, both participants and funders are expressing stronger needs for highly functional data and information capabilities. Characteristics include a) easy to use, b) highly integrated, c) leverage investments, d) accommodate rapid technical change, and e) do not incur undue expense or time to build or maintain - these are not a small set of requirements. Based on our accumulated experience over the last ~ decade and several key technical approaches, we adapt, extend, and integrate several open source applications and frameworks to handle major portions of functionality for these platforms. This includes: an object-type repository, collaboration tools, identity management, all within a portal managing diverse content and applications. In this contribution, we present our methods and results of information models, adaptation, integration and evolution of a networked data science architecture based on several open source technologies (Drupal, VIVO, the Comprehensive Knowledge Archive Network; CKAN, and the Global Handle System; GHS). In particular we present the Deep Carbon Observatory - a platform for international science collaboration. We present and discuss key functional and non-functional attributes, and discuss the general applicability of the platform.

Hunting, Swimming, and Worshiping: Human Cultural Practices Illuminate the Blood Meal Sources of Cave Dwelling Chagas Vectors (Triatoma dimidiata) in Guatemala and Belize

Background Triatoma dimidiata, currently the major Central American vector of Trypanosoma cruzi, the parasite that causes Chagas disease, inhabits caves throughout the region. This research investigates the possibility that cave dwelling T. dimidiata might transmit the parasite to humans and links the blood meal sources of cave vectors to cultural practices that differ among locations. Methodology/Principal Findings We determined the blood meal sources of twenty-four T. dimidiata collected from two locations in Guatemala and one in Belize where human interactions with the caves differ. Blood meal sources were determined by cloning and sequencing PCR products amplified from DNA extracted from the vector abdomen using primers specific for the vertebrate 12S mitochondrial gene. The blood meal sources were inferred by ≥99% identity with published sequences. We found 70% of cave-collected T. dimidiata positive for human DNA. The vectors had fed on 10 additional vertebrates with a variety of relationships to humans, including companion animal (dog), food animals (pig, sheep/goat), wild animals (duck, two bat, two opossum species) and commensal animals (mouse, rat). Vectors from all locations fed on humans and commensal animals. The blood meal sources differ among locations, as well as the likelihood of feeding on dog and food animals. Vectors from one location were tested for T. cruzi infection, and 30% (3/10) tested positive, including two positive for human blood meals. Conclusions/Significance Cave dwelling Chagas disease vectors feed on humans and commensal animals as well as dog, food animals and wild animals. Blood meal sources were related to human uses of the caves. We caution that just as T. dimidiata in caves may pose an epidemiological risk, there may be other situations where risk is thought to be minimal, but is not. PMID:25211347

Amid widespread reports of deforestation, some nations have nevertheless experienced transitions from deforestation to reforestation. In a causal relationship, the Forest Identity relates the carbon sequestered in forests to the changing variables of national or regional forest area, growing stock density per area, biomass per growing stock volume, and carbon concentration in the biomass. It quantifies the sources of change of a nation's forests. The Identity also logically relates the quantitative impact on forest expanse of shifting timber harvest to regions and plantations where density grows faster. Among 50 nations with extensive forests reported in the Food and Agriculture Organization's comprehensive Global Forest Resources Assessment 2005, no nation where annual per capita gross domestic product exceeded 4,600 dollars had a negative rate of growing stock change. Using the Forest Identity and national data from the Assessment report, a single synoptic chart arrays the 50 nations with coordinates of the rates of change of basic variables, reveals both clusters of nations and outliers, and suggests trends in returning forests and their attributes. The Forest Identity also could serve as a tool for setting forest goals and illuminating how national policies accelerate or retard the forest transitions that are diffusing among nations.

The present study contributes to a growing body of literature developing psychometrically and theoretically grounded measures of sexual orientation minority identity. We tested psychometric properties and construct validity of a 27-item measure, the Lesbian, Gay, and Bisexual Identity Scale (LGBIS). The sample consisted of 475 adult (178 male, 237 female, 16 male-to-female, 14 female-to-male, and 30 gender queer persons) members of a special interest group, the National Coalition for Sexual Freedom. Participants completed a health needs questionnaire. Prominent findings included (1) confirmatory factor-analytic, internal consistency, and inter-correlation patterns support two LGBIS factor structures; (2) men, compared primarily to women, reported elevated scores on Acceptance Concerns, Concealment Motivation, Difficulty Process, and Negative Identity; (3) queer-identifying persons tended to report low Concealment Motivation, and high Identity Affirmation and Identity Centrality scores; (4) experimenting/fluid-identifying individuals tended toward higher Identity Uncertainty and Negative Identity, and lower Identity Centrality scores; (5) LGB community involvement was negatively associated with Concealment Motivation, Identity Uncertainty, and Negative Identity, and positively associated with Identity Superiority, Identity Affirmation, and Identity Centrality scores; and (6) Acceptance Concerns, Identity Uncertainty, and Internalized Homonegativity displayed significant positive associations with such mental health symptoms as general anxiety and posttraumatic stress. The LGBIS represents a useful approach to evaluating sexual orientation minority identity. Implications for identity theory, research, and practice are provided.

The skepticism regarding the existence of dissociative identity disorder as well as the abuse that engenders it persists for lack of objective documentation. This is doubly so for the disorder in murderers because of issues of suspected malingering. This article presents objective verification of both dissociative symptoms and severe abuse during childhood in a series of adult murderers with dissociative identity disorder. This study consisted of a review of the clinical records of 11 men and one woman with DSM-IV-defined dissociative identity disorder who had committed murder. Data were gathered from medical, psychiatric, social service, school, military, and prison records and from records of interviews with subjects' family members and others. Handwriting samples were also examined. Data were analyzed qualitatively. Signs and symptoms of dissociative identity disorder in childhood and adulthood were corroborated independently and from several sources in all 12 cases; objective evidence of severe abuse was obtained in 11 cases. The subjects had amnesia for most of the abuse and underreported it. Marked changes in writing style and/or signatures were documented in 10 cases. This study establishes, once and for all, the linkage between early severe abuse and dissociative identity disorder. Further, the data demonstrate that the disorder can be distinguished from malingering and from other disorders. The study shows that it is possible, with great effort, to obtain objective evidence of both the symptoms of dissociative identity disorder and the abuse that engenders it.

Integration of disparate information from electronic health records, clinical data warehouses, birth certificate registries and other public health information systems offers great potential for clinical care, public health practice, and research. Such integration, however, depends on correctly matching patient-specific records using demographic identifiers. Without standards for these identifiers, record linkage is complicated by issues of structural and semantic heterogeneity. Objectives: Our objectives were to develop and validate an ontology to: 1) identify components of identity and events subsequent to birth that result in creation, change, or sharing of identity information; 2) develop an ontology to facilitate data integration from multiple healthcare and public health sources; and 3) validate the ontology’s ability to model identity-changing events over time. Methods: We interviewed domain experts in area hospitals and public health programs and developed process models describing the creation and transmission of identity information among various organizations for activities subsequent to a birth event. We searched for existing relevant ontologies. We validated the content of our ontology with simulated identity information conforming to scenarios identified in our process models. Results: We chose the Simple Event Model (SEM) to describe events in early childhood and integrated the Clinical Element Model (CEM) for demographic information. We demonstrated the ability of the combined SEM-CEM ontology to model identity events over time. Conclusion: The use of an ontology can overcome issues of semantic and syntactic heterogeneity to facilitate record linkage. PMID:26392849

Trends in wild food plants uses in Gorbeialdea (Basque Country).

Despite wild food plants' potential nutritional and economic value, their knowledge and consumption is quickly decreasing throughout the world. We examine how the consideration that a wild plant use is within the cultural tradition of a given area relates to its consumption by analysing 1) current perception and 2) past and present use of six wild plants' food-uses, of which only three are locally perceived as being part of the local tradition. Research was conducted in Gorbeialdea, an area in the Basque Country with a clearly marked Basque identity opposed to the Spanish identity. Overall, there is a clear decrease in the knowledge and consumption of the selected uses and especially of the three uses acquired from local sources (i.e., the consumption of the raw leaves of Fagus sylvatica and Rumex acetosa and of the fruits of Pyrus cordata). The trend is likely driven by the disappearance of the traditional agrarian lifestyle. Among the uses not acquired from local sources, the use recently adopted from another Basque-speaking area (i.e., macerating the fruits of Prunus spinosa to elaborate a liqueur) is now considered part of the local tradition by young generations, whereas the use acquired from southern Spanish migrants (i.e., using Laurus nobilis leaves as condiments) is not. While lifestyle changes largely explain overall trends in wild edibles consumption, other cultural aspects -in our case study the stigmatization of a given source of information associated to cultural identity- might help shape which new uses of wild plants become embedded in local traditions.

Feature level fusion of hand and face biometrics

Ross, Arun A.; Govindarajan, Rohin

2005-03-01

Multibiometric systems utilize the evidence presented by multiple biometric sources (e.g., face and fingerprint, multiple fingers of a user, multiple matchers, etc.) in order to determine or verify the identity of an individual. Information from multiple sources can be consolidated in several distinct levels, including the feature extraction level, match score level and decision level. While fusion at the match score and decision levels have been extensively studied in the literature, fusion at the feature level is a relatively understudied problem. In this paper we discuss fusion at the feature level in 3 different scenarios: (i) fusion of PCA and LDA coefficients of face; (ii) fusion of LDA coefficients corresponding to the R,G,B channels of a face image; (iii) fusion of face and hand modalities. Preliminary results are encouraging and help in highlighting the pros and cons of performing fusion at this level. The primary motivation of this work is to demonstrate the viability of such a fusion and to underscore the importance of pursuing further research in this direction.

A gastroenteritis outbreak was associated with playing in a norovirus-contaminated recreational fountain. A retrospective cohort study was performed to estimate the magnitude of the outbreak and identify its source. Epidemiological investigation included standardized questionnaires about sex, age, school, class, risk exposures, and illness characteristics. Stool samples and environmental water samples were analyzed for the presence of bacteria, viruses, and parasites. Questionnaires were returned for 191 schoolchildren (response rate, 83%) with a mean age of 9.2 years, of whom 47% were ill (diarrhea and/or vomiting). Children were more likely to have been ill if they had played in the recreational fountain (relative risk, 10.4). Norovirus (Birmingham) was detected in 22 (88%) stool specimens from ill children and in 6 (38%) specimens from healthy children. The water sample from the fountain contained a norovirus strain that was identical to the RNA sequence found in stools. Recreational water may be the source of gastroenteritis outbreaks. Adequate water treatment can prevent these types of outbreak.

Ten patients from a rehabilitation center were admitted to hospital with serious respiratory infections within ten weeks. An outbreak of Legionnaire's disease was suspected based on the epidemic and atypical manifestation of pneumonia and could be proven microbiologically. Pulmonary and extrapulmonary complications included respiratory failure, lung abscess, transitory renal impairment in five patients and acute renal failure requiring dialysis in one, tetraparesis caused by peripheral neuropathy and acute psychosis. Three patients died despite immediate institution of therapy with erythromycin. Legionella pneumophila serogroup 1 subtype Pontiac was isolated from a bronchial lavage sample of one patient and from the water supply of the rehabilitation center. Monoclonal antibody subtyping and restriction endonuclease analysis were performed on both environmental and patient isolates. Potable water was identified as the source of the outbreak based on identical patterns on restriction endonuclease analysis. Despite thermic and chemical disinfection with chlorination (up to 15 ppm) in the rehabilitation clinic, an eleventh case of Legionnaire's disease was detected 11 months later.

Waveguide quantum electrodynamics in squeezed vacuum

2018-02-01

We study the dynamics of a general multiemitter system coupled to the squeezed vacuum reservoir and derive a master equation for this system based on the Weisskopf-Wigner approximation. In this theory, we include the effect of positions of the squeezing sources which is usually neglected in the previous studies. We apply this theory to a quasi-one-dimensional waveguide case where the squeezing in one dimension is experimentally achievable. We show that while dipole-dipole interaction induced by ordinary vacuum depends on the emitter separation, the two-photon process due to the squeezed vacuum depends on the positions of the emitters with respect to the squeezing sources. The dephasing rate, decay rate, and the resonance fluorescence of the waveguide-QED in the squeezed vacuum are controllable by changing the positions of emitters. Furthermore, we demonstrate that the stationary maximum entangled NOON state for identical emitters can be reached with arbitrary initial state when the center-of-mass position of the emitters satisfies certain conditions.

This study aimed to determine the changes over time in sexual attitude and behavior among adolescents, and to measure the effect of sources information about sex on these changes. This study was conducted in 2 stages, the first in 1996 and the second in 2004. In all, 392 male tenth grade students (150 in the first stage and 242 in the second stage) were evaluated. A personal information questionnaire developed by the authors was used to collect sociodemographic data, including sexual behavior, sexual attitude, and sources of information about sex. The findings show that there was a significant increase in intercourse and flirting behavior from 1996 to 2004, although no significant difference in masturbation was observed. Additionally, the number of male adolescents that reported family and pornographic films as their sources of information about sex increased 1.6-fold and 2.9-fold, respectively. A significant relationship between watching pornographic films and engaging in sexual intercourse was noted. The number of male adolescents age mean 16, engaging in sexual intercourse increased between 1996 and 2004. Pornographic films were observed to be the most common source of information about sex and also predicted the probability of adolescents having sex. Findings that indicate the need for better and more accurate sources of information about sex. The availability of good quality information about sex is critical to the development of the sexual identity and mental health of male adolescents.

Objectives To prospectively intra-individually compare image quality of a 3rd generation Dual-Source-CT (DSCT) spiral cranial CT (cCT) to a sequential 4-slice Multi-Slice-CT (MSCT) while maintaining identical intra-individual radiation dose levels. Methods 35 patients, who had a non-contrast enhanced sequential cCT examination on a 4-slice MDCT within the past 12 months, underwent a spiral cCT scan on a 3rd generation DSCT. CTDIvol identical to initial 4-slice MDCT was applied. Data was reconstructed using filtered backward projection (FBP) and 3rd-generation iterative reconstruction (IR) algorithm at 5 different IR strength levels. Two neuroradiologists independently evaluated subjective image quality using a 4-point Likert-scale and objective image quality was assessed in white matter and nucleus caudatus with signal-to-noise ratios (SNR) being subsequently calculated. Results Subjective image quality of all spiral cCT datasets was rated significantly higher compared to the 4-slice MDCT sequential acquisitions (p<0.05). Mean SNR was significantly higher in all spiral compared to sequential cCT datasets with mean SNR improvement of 61.65% (p*Bonferroni0.05<0.0024). Subjective image quality improved with increasing IR levels. Conclusion Combination of 3rd-generation DSCT spiral cCT with an advanced model IR technique significantly improves subjective and objective image quality compared to a standard sequential cCT acquisition acquired at identical dose levels.

Long-term information and distributed neural activation are relevant for the "internal features advantage" in face processing: electrophysiological and source reconstruction evidence.

Olivares, Ela I; Saavedra, Cristina; Trujillo-Barreto, Nelson J; Iglesias, Jaime

2013-01-01

In face processing tasks, prior presentation of internal facial features, when compared with external ones, facilitates the recognition of subsequently displayed familiar faces. In a previous ERP study (Olivares & Iglesias, 2010) we found a visibly larger N400-like effect when identity mismatch familiar faces were preceded by internal features, as compared to prior presentation of external ones. In the present study we contrasted the processing of familiar and unfamiliar faces in the face-feature matching task to assess whether the so-called "internal features advantage" relies mainly on the use of stored face-identity-related information or if it might operate independently from stimulus familiarity. Our participants (N = 24) achieved better performance with internal features as primes and, significantly, with familiar faces. Importantly, ERPs elicited by identity mismatch complete faces displayed a negativity around 300-600 msec which was clearly enhanced for familiar faces primed by internal features when compared with the other experimental conditions. Source reconstruction showed incremented activity elicited by familiar stimuli in both posterior (ventral occipitotemporal) and more anterior (parahippocampal (ParaHIP) and orbitofrontal) brain regions. The activity elicited by unfamiliar stimuli was, in general, located in more posterior regions. Our findings suggest that the activation of multiple neural codes is required for optimal individuation in face-feature matching and that a cortical network related to long-term information for face-identity processing seems to support the internal feature effect.

Quantifying the Correctness, Computational Complexity, and Security of Privacy-Preserving String Comparators for Record Linkage

2011-01-01

Record linkage is the task of identifying records from disparate data sources that refer to the same entity. It is an integral component of data processing in distributed settings, where the integration of information from multiple sources can prevent duplication and enrich overall data quality, thus enabling more detailed and correct analysis. Privacy-preserving record linkage (PPRL) is a variant of the task in which data owners wish to perform linkage without revealing identifiers associated with the records. This task is desirable in various domains, including healthcare, where it may not be possible to reveal patient identity due to confidentiality requirements, and in business, where it could be disadvantageous to divulge customers' identities. To perform PPRL, it is necessary to apply string comparators that function in the privacy-preserving space. A number of privacy-preserving string comparators (PPSCs) have been proposed, but little research has compared them in the context of a real record linkage application. This paper performs a principled and comprehensive evaluation of six PPSCs in terms of three key properties: 1) correctness of record linkage predictions, 2) computational complexity, and 3) security. We utilize a real publicly-available dataset, derived from the North Carolina voter registration database, to evaluate the tradeoffs between the aforementioned properties. Among our results, we find that PPSCs that partition, encode, and compare strings yield highly accurate record linkage results. However, as a tradeoff, we observe that such PPSCs are less secure than those that map and compare strings in a reduced dimensional space. PMID:22904698

Alternative generation of CNS neural stem cells and PNS derivatives from neural crest-derived peripheral stem cells.

Neural crest-derived stem cells (NCSCs) from the embryonic peripheral nervous system (PNS) can be reprogrammed in neurosphere (NS) culture to rNCSCs that produce central nervous system (CNS) progeny, including myelinating oligodendrocytes. Using global gene expression analysis we now demonstrate that rNCSCs completely lose their previous PNS characteristics and acquire the identity of neural stem cells derived from embryonic spinal cord. Reprogramming proceeds rapidly and results in a homogenous population of Olig2-, Sox3-, and Lex-positive CNS stem cells. Low-level expression of pluripotency inducing genes Oct4, Nanog, and Klf4 argues against a transient pluripotent state during reprogramming. The acquisition of CNS properties is prevented in the presence of BMP4 (BMP NCSCs) as shown by marker gene expression and the potential to produce PNS neurons and glia. In addition, genes characteristic for mesenchymal and perivascular progenitors are expressed, which suggests that BMP NCSCs are directed toward a pericyte progenitor/mesenchymal stem cell (MSC) fate. Adult NCSCs from mouse palate, an easily accessible source of adult NCSCs, display strikingly similar properties. They do not generate cells with CNS characteristics but lose the neural crest markers Sox10 and p75 and produce MSC-like cells. These findings show that embryonic NCSCs acquire a full CNS identity in NS culture. In contrast, MSC-like cells are generated from BMP NCSCs and pNCSCs, which reveals that postmigratory NCSCs are a source for MSC-like cells up to the adult stage. © 2014 AlphaMed Press.

An integrated developmental model for studying identity content in context.

PubMed

Galliher, Renee V; McLean, Kate C; Syed, Moin

2017-11-01

Historically, identity researchers have placed greater emphasis on processes of identity development (how people develop their identities) and less on the content of identity (what the identity is). The relative neglect of identity content may reflect the lack of a comprehensive framework to guide research. In this article, we provide such a comprehensive framework for the study of the content of identity, including 4 levels of analysis. At the broadest level, we situate individual identity within historical, cultural, and political contexts, elaborating on identity development within the context of shifting cultural norms, values, and attitudes. Histories of prejudice and discrimination are relevant in shaping intersections among historically marginalized identities. Second, we examine social roles as unique and central contexts for identity development, such that relationship labels become integrated into a larger identity constellation. Third, domains of individual or personal identity content intersect to yield a sense of self in which various aspects are subjectively experienced as an integrated whole. We explore the negotiation of culturally marginalized and dominant identity labels, as well as idiosyncratic aspects of identities based on unique characteristics or group memberships. Finally, we argue that the content of identity is enacted at the level of everyday interactions, the "micro-level" of identity. The concepts of identity conflict, coherence, and compartmentalization are presented as strategies used to navigate identity content across these 4 levels. This framework serves as an organizing tool for the current literature, as well as for designing future studies on the identity development.

The Relationship Between Continuous Identity Disturbances, Negative Mood, and Suicidal Ideation.

PubMed

Sokol, Yosef; Eisenheim, Edouard

To examine the relationship between continuous identity and a measure of depression, anxiety, and stress as well as suicidal ideation using 2 validated measures of continuous identity. A total of 246 subjects recruited from the Amazon Mechanical Turk subject pool who completed a full survey in November 2014 were included in the analyses. Stress, anxiety, and depression severity were measured using the Depression, Anxiety, and Stress Scale. Continuous identity was measured with the Venn continuous identity task and the me/not me continuous identity task. Multiple regression analyses revealed continuous identity disturbances were significantly associated with depressed mood (R (2) = 0.37, P < .01). Continuous identity also predicted suicide severity, even after controlling for demographic factors, negative life events, and depressed mood. Additionally, predictive discriminant analysis revealed continuous identity, depression severity, and negative life events correctly classified 74.1% of participants into high and low suicide risk groups. Lack of continuous identity predicted both depression and suicidality severity. Integration of perceived identities may be a worthwhile goal for behavioral interventions aimed at reducing depressed mood and suicidality.

Bringing social identity to work: the influence of manifestation and suppression on perceived discrimination, job satisfaction, and turnover intentions.

2012-04-01

In the current article, we explored whether manifesting or suppressing an identity (race/ethnicity, gender, age, religion, sexual orientation, or disability) at work is related to perceived discrimination, job satisfaction, and turnover intentions. Participants included 211 working adults who completed an online survey. The results showed that efforts to suppress a group identity were positively (and behavioral manifestations of group identity negatively) related to perceived discrimination, which predicted job satisfaction and turnover intentions. These results suggest that diverse employees actively manage their nonwork identities while at work and that these identity management strategies have important consequences.

The aim of this work is to analyse the effect of pH, fungal identity and P chemical nature on microbial development and phosphatase release, discussing solubilization and mineralization processes in P cycling. P solubilizing fungi (Talaromyces flavus, T. helicus L, T. helicus N, T. diversus and Penicillium purpurogenum) were grown under three pH conditions (6, 6·5 and 8·5) and with different inorganic (calcium, iron, aluminium and rock) and organic (lecithin and phytate) P sources. P solubilization, mineralization, growth and phosphatase production were recorded. Acid and neutral environments maximized fungal development and P recycling. P chemical nature changed the phosphatases release pattern depending on the fungal identity. Acid phosphatase activity was higher than alkaline phosphatases, regardless of pH or sample times. Alkaline phosphatases were affected by a combination of those factors. P chemical nature and pH modify fungal growth, P mineralization and solubilization processes. The underlying fungal identity-dependent metabolism governs the capacity and efficiency of P solubilization and mineralization. P solubilization and mineralization processes are interrelated and simultaneously present in soil fungi. This study constitutes a reference work to improve the selection of fungal bioinoculants in different environmental conditions, highlighting their role in P cycling. © 2017 The Society for Applied Microbiology.

Exploring Medical Identity Theft

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

2017-01-01

Becoming a doctor is fundamentally about developing a new, professional identity as a physician, which in and of itself may evoke many emotions. Additionally, medical trainees are increasingly moving from one cultural context to another and are challenged with navigating the resulting shifts in their professional identify. In this Article, the authors aim to address medical professional identity formation from a polyvocal, multidisciplinary, cross-cultural perspective. They delineate the cultural approaches to medical professionalism, reflect on professional identity formation in different cultures and on different theories of identity development, and advocate for a context-specific approach to professional identity formation. In doing so, the authors aim to broaden the developing professional identity formation discourse to include non-Western approaches and notions.

Mental Well-Being and Sport-Related Identities in College Students

Miller, Kathleen E.; Hoffman, Joseph H.

2010-01-01

Past research has linked physical activity and sports participation with improved mental and social well-being, including reduced risk of depression and suicidality. In this study we examined relationships among several dimensions of athletic involvement (team sport participation, individual sport participation, athlete identity, and jock identity), gender, and depression and suicidal behavior in a sample of 791 undergraduate students. Both participation in a team sport and athlete identity were associated with lower depression scores. Athlete identity was also associated with lower odds of a past-year suicide attempt, whereas jock identity was associated with elevated odds of a suicide attempt. The findings are discussed in light of the relationship between mental well-being and a larger constellation of health-risk behaviors linked to a “toxic jock” identity. PMID:20661467

The role of gender and sexual relations for young people in identity construction and youth suicide.

Gilchrist, Heidi; Sullivan, Gerard

2006-01-01

The suicide rate among young people in Australia has caused considerable concern and been the focus of research and intervention. Issues related to sexuality and gender can be the source of conflict for young people within their communities, and have been implicated in suicide attempts. This paper examines the cultural context of youth suicide, and asks how youth suicide may be related to emerging sexual identity, which all young people must negotiate through the customs, discourse and taboos of their society. In particular, it focuses on the situation of young heterosexual women. The findings are based on interviews with 41 young people, parents and youth service providers regarding youth suicide. Interviews were semi-structured and open-ended, and conducted in a suburban community. They included the use of scenarios or vignettes. Finding, suggest that traditional constructions of gender remain widespread, and that these are often disadvantageous to both young women and young men. Parents may be unaware that they have little control over, or even knowledge about, their teenagers' behaviour. Young people are more inclined to confide in their friends, who may not be equipped to deal with crises.

Emerging Biometric Modalities: Challenges and Opportunities

NASA Astrophysics Data System (ADS)

Gafurov, Davrondzhon

Recent advances in sensor technology and wide spread use of various electronics (computers, PDA, mobile phones etc.) provide new opportunities for capturing and analyses of novel physiological and behavioural traits of human beings for biometric authentication. This paper presents an overview of several such types of human characteristics that have been proposed as alternatives to traditional types of biometrics. We refer to these characteristics as emerging biometrics. We survey various types of emerging modalities and techniques, and discuss their pros and cons. Emerging biometrics faces several limitations and challenges which include subject population coverage (focusing mostly on adults); unavailability of benchmark databases; little research with respect to vulnerability/robustness against attacks; and some privacy concerns they may arise. In addition, recognition performance of emerging modalities are generally less accurate compared to the traditional biometrics. Despite all of these emerging biometrics posses their own benefits and advantages compared to traditional biometrics which makes them still attractive for research. First of all, emerging biometrics can always serve as a complementary source for identity information; they can be suitable in applications where traditional biometrics are difficult or impossible to adapt such as continuous or periodic re-verification of the user's identity etc.

Neurodegeneration and Identity.

Strohminger, Nina; Nichols, Shaun

2015-09-01

There is a widespread notion, both within the sciences and among the general public, that mental deterioration can rob individuals of their identity. Yet there have been no systematic investigations of what types of cognitive damage lead people to appear to no longer be themselves. We measured perceived identity change in patients with three kinds of neurodegenerative disease: frontotemporal dementia, Alzheimer's disease, and amyotrophic lateral sclerosis. Structural equation models revealed that injury to the moral faculty plays the primary role in identity discontinuity. Other cognitive deficits, including amnesia, have no measurable impact on identity persistence. Accordingly, frontotemporal dementia has the greatest effect on perceived identity, and amyotrophic lateral sclerosis has the least. We further demonstrated that perceived identity change fully mediates the impact of neurodegenerative disease on relationship deterioration between patient and caregiver. Our results mark a departure from theories that ground personal identity in memory, distinctiveness, dispositional emotion, or global mental function. © The Author(s) 2015.

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.

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.

Potentially pathogenic members of the Vibrionaceae family including Vibrio cholerae and Vibrio parahemolyticus were isolated from domestic sources of drinking water in coastal villages following sea water inundation during the tsunami in Southern India. Phenotypic and genotypic studies were done to confirm the identity and detection of toxins. Vibrio-gyr (gyrase B gene) was detected in all sixteen vibrio isolates. Toxin regulating genes i.e.: ctx gene, tdh gene, and trh gene, however were not detected in any of the strains, thereby ruling out presence of toxins which could endanger human life. Other potentially pathogenic bacteria Aeromonas and Plesiomonas were also isolated from hand pumps and wells, in a few localities. There was no immediate danger in the form of an outbreak or sporadic gastroenteritis at the time of the study. Timely chlorination and restoration of potable water supply to the flood affected population by governmental and nongovernmental agencies averted waterborne gastroenteritis. Assessment of quality of water and detection of potential virulent organisms is an important public health activity following natural disasters. This work highlights the importance of screening water sources for potentially pathogenic microorganisms after natural disasters to avert outbreaks of gastroenteritis and other infectious diseases.

Social media sites, composed of providers, patients, and their social circles, facilitate health and healthcare delivery. To examine patients' perspective on social media as an information source, communication tool, and referral service through an anonymous survey. In addition, influences on patient Internet personas, an actively constructed online identity, around the time of cosmetic procedures are examined. Patients completed an anonymous institutional review board-approved survey during their initial cosmetic visit. Patients are highly active on social media using it as a multipurpose tool for physician referral services, support groups, and disease education. Patients gathered dermatology information from multiple sources, including friends, family, social media pages, and other online sources, often sharing their own experiences through social media platforms. Patients indicated a desire for provider educational materials on interactive media pages. Most preferred material written by a physician, but some indicated a preference for both physician and lay material. Online images highlighting dissatisfying skin features were influential to select patients, prompting manipulation of online personas and evaluation for aesthetic procedures. Although the study examines cosmetic patient perspectives, data highlight valuable trends for all dermatologists. Social media can improve patient education, collaboration, recruitment, and online professional image, leading to healthier patient-centered care.

Smoking-related self-identity processes are important for smoking cessation. We examined whether quitter self-identity (i.e. identification with quitting smoking) could be strengthened through a writing exercise, and whether expected social support for quitting, manipulated through vignettes, could facilitate identification with quitting. Participants (N = 339 daily smokers) were randomly assigned to a 2 (identity: strengthened quitter self-identity vs. control) × 3 (social support: present vs. absent vs. neutral control) between-participants design. The main outcome was post-test quitter self-identity. Post-test quitter self-identity was not strengthened successfully. Only a small and marginally significant intervention effect was found on quitter self-identity, which did not generalise to positively influence quit-intention or behaviour. The social support manipulation did not facilitate quitter self-identity. Secondary content analyses showed that quitter self-identity was strengthened among participants who linked quitting smoking to their lifestyle, wanted to become quitters for health reasons, and whose reasons for becoming quitters included approach of positive aspects of quitting, but not among participants who linked quitter self-identity to their self-perceptions. Results provide insight into the content of smokers' self-conceptualizations as quitters. Writing exercises should be improved and tested to eventually successfully strengthen quitter identities.

Blood from a turnip: tissue origin of low-coverage shotgun sequencing libraries affects recovery of mitogenome sequences

Barker, F. Keith; Oyler-McCance, Sara; Tomback, Diana F.

2015-01-01

Next generation sequencing methods allow rapid, economical accumulation of data that have many applications, even at relatively low levels of genome coverage. However, the utility of shotgun sequencing data sets for specific goals may vary depending on the biological nature of the samples sequenced. We show that the ability to assemble mitogenomes from three avian samples of two different tissue types varies widely. In particular, data with coverage typical of microsatellite development efforts (∼1×) from DNA extracted from avian blood failed to cover even 50% of the mitogenome, relative to at least 500-fold coverage from muscle-derived data. Researchers should consider possible applications of their data and select the tissue source for their work accordingly. Practitioners analyzing low-coverage shotgun sequencing data (including for microsatellite locus development) should consider the potential benefits of mitogenome assembly, including internal barcode verification of species identity, mitochondrial primer development, and phylogenetics.

Reducing the risk of contamination of sterile parenteral products via ready-to-use closure components.

2010-12-01

The preparation of sterile parenteral products requires careful control of all ingredients, materials, and processes to ensure the final product has the identity and strength, and meets the quality and purity characteristics that it purports to possess. Contamination affecting these critical properties of parenteral products can occur in many ways and from many sources. The use of closures supplied by manufacturers in a ready-to-use state can be an effective method for reducing the risk of contamination and improving the quality of the drug product. This article will address contamination attributable to elastomeric container closure components and the regulatory requirements associated with container closure systems. Possible contaminants, including microorganisms, endotoxins, and chemicals, along with the methods by which these contaminants can enter the product will be reviewed. Such methods include inappropriate material selection, improper closure preparation processes, compromised container closure integrity, degradation of closures, and leaching of compounds from the closures.

Because the majority of this research confounds these constructs, there is little evidence as to the discrete roles religiosity and spirituality may play in LGB identity development. The present study endeavored to tease apart the unique effects of religion and spirituality on positive and negative gay identity and self-esteem. A sample of 376 self-identified sexual minority adults were given measures of religiosity, spirituality, LGB identity, and self-esteem. Models were built to evaluate the effects of religiosity (independent of spirituality) and spirituality (independent of religiosity), understanding that the constructs are greatly overlapped, on identity and self-esteem. Results included a positive association between spirituality and identity affirmation, identity superiority, and self-esteem. Religiosity was negatively associated with identity affirmation and self-esteem and positively associated with internalized homonegativity and heteronormativity. Limitations and implications are discussed.

Hemiclonal analysis of interacting phenotypes in male and female Drosophila melanogaster

PubMed Central

2014-01-01

Background Identifying the sources of variation in mating interactions between males and females is important because this variation influences the strength and/or the direction of sexual selection that populations experience. While the origins and effects of variation in male attractiveness and ornamentation have received much scrutiny, the causes and consequences of intraspecific variation in females have been relatively overlooked. We used cytogenetic cloning techniques developed for Drosophila melanogaster to create “hemiclonal” males and females with whom we directly observed sexual interaction between individuals of different known genetic backgrounds and measured subsequent reproductive outcomes. Using this approach, we were able to quantify the genetic contribution of each mate to the observed phenotypic variation in biologically important traits including mating speed, copulation duration, and subsequent offspring production, as well as measure the magnitude and direction of intersexual genetic correlation between female choosiness and male attractiveness. Results We found significant additive genetic variation contributing to mating speed that can be attributed to male genetic identity, female genetic identity, but not their interaction. Furthermore we found that phenotypic variation in copulation duration had a significant male-associated genetic component. Female genetic identity and the interaction between male and female genetic identity accounted for a substantial amount of the observed phenotypic variation in egg size. Although previous research predicts a trade-off between egg size and fecundity, this was not evident in our results. We found a strong negative genetic correlation between female choosiness and male attractiveness, a result that suggests a potentially important role for sexually antagonistic alleles in sexual selection processes in our population. Conclusion These results further our understanding of sexual selection because they identify that genetic identity plays a significant role in phenotypic variation in female behaviour and fecundity. This variation may be potentially due to ongoing sexual conflict found between the sexes for interacting phenotypes. Our unexpected observation of a negative correlation between female choosiness and male attractiveness highlights the need for more explicit theoretical models of genetic covariance to investigate the coevolution of female choosiness and male attractiveness.

SELF-CALIBRATION OF COSMIC MICROWAVE BACKGROUND POLARIZATION EXPERIMENTS

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

Keating, Brian G.; Yadav, Amit P. S.; Shimon, Meir

2013-01-10

Precision measurements of the polarization of the cosmic microwave background (CMB) radiation, especially experiments seeking to detect the odd-parity 'B-modes', have far-reaching implications for cosmology. To detect the B-modes generated during inflation, the flux response and polarization angle of these experiments must be calibrated to exquisite precision. While suitable flux calibration sources abound, polarization angle calibrators are deficient in many respects. Man-made polarized sources are often not located in the antenna's far-field, have spectral properties that are radically different from the CMB's, are cumbersome to implement, and may be inherently unstable over the (long) duration these searches require to detectmore » the faint signature of the inflationary epoch. Astrophysical sources suffer from time, frequency, and spatial variability, are not visible from all CMB observatories, and none are understood with sufficient accuracy to calibrate future CMB polarimeters seeking to probe inflationary energy scales of 10{sup 15} GeV. Both man-made and astrophysical sources require dedicated observations which detract from the amount of integration time usable for detection of the inflationary B-modes. CMB TB and EB modes, expected to identically vanish in the standard cosmological model, can be used to calibrate CMB polarimeters. By enforcing the observed EB and TB power spectra to be consistent with zero, CMB polarimeters can be calibrated to levels not possible with man-made or astrophysical sources. All of this can be accomplished for any polarimeter without any loss of observing time using a calibration source which is spectrally identical to the CMB B-modes.« less

2016-10-01

Shared decision making (SDM) is a model of patient-provider communication. Little is known about the role of SDM in health disparities among Asian American and Pacific Islander (AAPI) sexual and gender minorities (SGM). We illustrate how issues at the intersection of AAPI and SGM identities affect SDM processes and health outcomes. We discuss experiences of AAPI SGM that are affected by AAPI heterogeneity, SGM stigma, multiple minority group identities, and sources of discrimination. Recommendations for clinical practice, research, policy, community development, and education are offered.

Patient Perceptions of Illness Identity in Cancer Clinical Trial Decision-Making.

Palmer-Wackerly, Angela L; Dailey, Phokeng M; Krok-Schoen, Jessica L; Rhodes, Nancy D; Krieger, Janice L

2018-08-01

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.

Testing a Model of Minority Identity Achievement, Identity Affirmation and Psychological Well-Being among Ethnic Minority and Sexual Minority Individuals

PubMed Central

2011-01-01

How is social identity related to psychological well-being among minority individuals? Drawing on developmental models of identity formation (e.g., Erikson, 1968) and on Social Identity Theory (Tajfel & Turner, 1979), we tested a conceptual model examining links between two key aspects of social identity and psychological well-being. We proposed that the association between identity achievement (exploring and understanding the meaning of one’s identity) and psychological well-being is mediated by identity affirmation (developing positive feelings and a sense of belonging to one’s social group). Across three studies, including ethnic minority high school students (Study 1), ethnic minority college students (Study 2) and lesbian and gay male adults (Study 3), we found strong support for the model. Results suggest that the process of exploring and understanding one’s minority identity can serve as an important basis for developing positive feelings toward and an enhanced sense of attachment to the group which can in turn confer psychological benefits for minority individuals. Implications and directions for future research are discussed. PMID:21341900

Exploring the positional identities of high school science teachers

NASA Astrophysics Data System (ADS)

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.

2018-02-01

The aim of this multiple case study was to uncover a series of critical events and experiences related to the formation of the science identities of four beginning elementary female teachers, through a life-history approach and a conceptualization of teacher identity as lived experience. Grounded within the theoretical framework of Figured Worlds, the study used qualitative, interpretive methods for data collection (interviews, biographies, teaching philosophies) and analysis. The analysis shed light on the ways in which various experiences situated within different Figured Worlds (science, family and childhood, schooling, out-of-school, university, professional) impacted the participants' identity trajectories. The findings provided three main insights that contribute to science identity research and have implications for elementary teacher preparation: (a) science teacher identity is multidimensional and extends beyond cognitive domains of becoming to include affective dimensions; (b) science teacher identity is relational, linked and shaped by various other constructs or sub-identities; (c) place and time, defined as a space with meaning created by experiences, and science teacher identity are inextricably bound to one another.

On the Statistical Dependency of Identity Theft on Demographics

NASA Astrophysics Data System (ADS)

di Crescenzo, Giovanni

An improved understanding of the identity theft problem is widely agreed to be necessary to succeed in counter-theft efforts in legislative, financial and research institutions. In this paper we report on a statistical study about the existence of relationships between identity theft and area demographics in the US. The identity theft data chosen was the number of citizen complaints to the Federal Trade Commission in a large number of US municipalities. The list of demographics used for any such municipality included: estimated population, median resident age, estimated median household income, percentage of citizens with a high school or higher degree, percentage of unemployed residents, percentage of married residents, percentage of foreign born residents, percentage of residents living in poverty, density of law enforcement employees, crime index, and political orientation according to the 2004 presidential election. Our study findings, based on linear regression techniques, include statistically significant relationships between the number of identity theft complaints and a non-trivial subset of these demographics.

Procedural memory in dissociative identity disorder: when can inter-identity amnesia be truly established?

2005-06-01

In a serial reaction time task, procedural memory was examined in Dissociative Identity Disorder (DID). Thirty-one DID patients were tested for inter-identity transfer of procedural learning and their memory performance was compared with 25 normal controls and 25 controls instructed to simulate DID. Results of patients seemed to indicate a pattern of inter-identity amnesia. Simulators, however, were able to mimic a pattern of inter-identity amnesia, rendering the results of patients impossible to interpret as either a pattern of amnesia or a pattern of simulation. It is argued that studies not including DID-simulators or simulation-free memory tasks, should not be taken as evidence for (or against) amnesia in DID.

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.

The strong UV source in the active E Galaxy NGC 4552

1200-3200 A IUE spectra of the nucleus of NGC 4552 (M89) were obtained in order to investigate the nature of the strong 10 micron source in this Galaxy. There is a strong, extended UV source in NGC 4552 which has a spatial distribution nearly identical with that at optical wavelengths and is undoubedly stellar in origin. Its properties are consistent with the correlation between UV source strength and metallicity pointed out by Faber (1983). There is no evidence for a nonthermal point source in the UV. It appears unlikely that the 10 micron emission is from heated dust grains. Instead, it is believed the 10 micron radiation is nonthermal in origin, implying a remarkably small size of only 0.1 AU for this source.

Risk perception and health behaviors result from individual-level factors influenced by specific partnership contexts. We explored individual- and partner-level factors associated with partner-specific perceptions of HIV/STI risk among 372 HIV/STI-positive MSM and transgender women (TW) in Lima, Peru. Generalized estimating equations explored participants' perception of their three most recent partner(s) as a likely source of their HIV/STI diagnosis. Homosexual/gay (PR = 2.07; 95 % CI 1.19-3.61) or transgender (PR = 2.84; 95 % CI 1.48-5.44) partners were more likely to be considered a source of infection than heterosexual partners. Compared to heterosexual respondents, gay and TW respondents were less likely to associate their partner with HIV/STI infection, suggesting a cultural link between gay or TW identity and perceived HIV/STI risk. Our findings demonstrate a need for health promotion messages tailored to high-risk MSM partnerships addressing how perceived HIV/STI risk aligns or conflicts with actual transmission risks in sexual partnerships and networks.

Single-photon emitters play an important role in many leading quantum technologies. There is still no 'ideal' on-demand single-photon emitter, but a plethora of promising material systems have been developed, and several have transitioned from proof-of-concept to engineering efforts with steadily improving performance. Here, we review recent progress in the race towards true single-photon emitters required for a range of quantum information processing applications. We focus on solid-state systems including quantum dots, defects in solids, two-dimensional hosts and carbon nanotubes, as these are well positioned to benefit from recent breakthroughs in nanofabrication and materials growth techniques. We consider the main challenges and key advantages of each platform, with a focus on scalable on-chip integration and fabrication of identical sources on photonic circuits.

2014-01-01

Research into the dissemination of health information now includes more focus on how various organizations (e.g., beauty shops, schools, workplaces, and churches) and health information technologies (HITs) reach and affect audiences. One relational feature of organizations is identification--the feeling of belongingness. Our study explores how it influences audiences, especially in combination with HITs such as e-mail, websites, and social media. We use social identity theory to predict how organizational identification and social media might function in health communication. Using a 3 × 2 experimental design, we find that people's identification with a message source mediates the effect of social media on outcomes. These findings improve our understanding of when organizations might be most helpful for disseminating health information.

The identical-twin transfusion syndrome: a source of error in estimating IQ resemblance and heritability.

PubMed

Munsinger, H

1977-01-01

Published studies show that among identical twins, lower birthweight is associated with lower adult intelligence. However, no such relation between birthweight and adult IQ exists among fraternal twins. A likely explanation for the association between birthweight and intelligence among identical twins is the identical twin transfusion syndrome which occurs only between some monochorionic identical twin pairs. The IQ scores from separated identical twins were reanalysed to explore the consequences of identical twin transfusion syndrome for IQ resemblance and heritability. Among 129 published cases of identical twin pairs reared apart, 76 pairs contained some birthweight information. The 76 pairs were separated into three classes: 23 pairs in which there was clear evidence of a substantial birthweight differences (indicating the probable existence of the identical twin transfusion syndrome), 27 pairs in which the information on birthweight was ambiguous (?), and 26 pairs in which there was clear evidence that the twins were similar in birthweight. The reanalyses showed: (1) birthweight differences are positively associated with IQ differences in the total sample of separated identical twins; (2) within the group of 23 twin pairs who showed large birthweight differences, there was a positive relation between birthweight differences and IQ differences; (3) when heritability of IQ is estimated for those twins who do not suffer large birthweight differences, the resemblance (and thus, h2/b) of the separated identical twins' IG is 0-95. Given that the average reliability of the individual IQ test is around 0-95, these data suggest that genetic factors and errors of measurement cause the individual differences in IQ among human beings. Because of the identical twin transfusion syndrome, previous studies of MZ twins have underestimated the effect of genetic factors on IQ. An analysis of the IQs for heavier and lighter birthweight twins suggests that the main effect of the identical twin transfusion syndrome is to lower the IQ of the lighter birthweight twin, rather than to raise the IQ of the more fortunate partner or to influence the IQ of both members. This reanalysis suggests that postnatal cultural and social environment produce little of the total phenotypic variation in IQ found in the normal population. In the future, investigators who use twin studies to estimated heritability must ascertain whether their identical twin pairs suffered from the identical twin transfusion syndrome. Accurate estimates of heritability can only be obtained using identical twins who do not suffer from placental circulation problems. Most likely, the identical twin transfusion syndrome produces anoxia and brain damage during early prenatal development in the smaller identical twin. The anoxia is caused by a lowering of the haemoglobin content of the smaller twin by 35% or more.

This first source used an ECR frequency of 14.3 GHz in the injector stage and 8.5 GHz in the main confinement stage. A new OCTOPUS source has now been built for a new cyclotron to be installed at the Japan Atomic Energy Research Institute (JAERI). The design of this new OCTOPUS source is identical to the first OCTOPUS source, but uses an ECR frequency of 6.4 GHz in the main confinement stage.more » The experimental results are described, and a comparison is made between the two sources.

Achieving Privacy in a Federated Identity Management System

NASA Astrophysics Data System (ADS)

Landau, Susan; Le van Gong, Hubert; Wilton, Robin

Federated identity management allows a user to efficiently authenticate and use identity information from data distributed across multiple domains. The sharing of data across domains blurs security boundaries and potentially creates privacy risks. We examine privacy risks and fundamental privacy protections of federated identity- management systems. The protections include minimal disclosure and providing PII only on a “need-to-know” basis. We then look at the Liberty Alliance system and analyze previous privacy critiques of that system. We show how law and policy provide privacy protections in federated identity-management systems, and that privacy threats are best handled using a combination of technology and law/policy tools.

Discrimination, Racial/Ethnic Identity, and Substance Use Among Latina/os: Are They Gendered?

PubMed

Molina, Kristine M; Jackson, Benita; Rivera-Olmedo, Noemi

2016-02-01

Prior research suggests that stronger racial/ethnic identification offsets negative effects of discrimination on substance use. Yet research in this area and on whether gender modifies this association is limited for Latina/os. The purpose of the present study is to examine whether different sources of discrimination (everyday and racial/ethnic) are associated with substance use (alcohol use disorder, smoking), if racial/ethnic identity buffers this association, and the potential moderating role of gender among these variables. We present cross-sectional, US population-based data from the Latina/o adult sample (1427 females and 1127 males) of the National Latino and Asian American Study. Respondents completed self-reported measures of everyday and racial/ethnic discrimination, racial/ethnic identity, smoking status, and Diagnostic and Statistical Manual of Mental Disorders, 4th edition (DSM-IV) lifetime alcohol use disorder. Weighted logistic regression analyses showed that before inclusion of three-way interactions and adjusting for covariates, everyday discrimination predicted increased risk for any DSM-IV lifetime alcohol use disorders. Moderation analyses revealed that the effect of everyday discrimination on the risk of being a current smoker was strongest for Latino men with high levels of racial/ethnic identity compared to those with low racial/ethnic identity. No differences were noted among Latino women. There were no main or interaction effects of racial/ethnic discrimination for any substance use outcome. Findings suggest differential associations for type of discrimination and outcome and that the role of racial/ethnic identity is gender-specific for smoking, appearing particularly detrimental for Latino men reporting high levels of racial/ethnic identity.

Gender role influences on Turkish adolescents' self-identity.

PubMed

Yildirim, A

1997-01-01

This study investigated gender role influences on Turkish adolescents' self-identity process as part of the International Self-Identity Research Project. A total of 154 male and 119 female adolescents ages 14 through 17 from urban and rural areas of Turkey were surveyed through a questionnaire. The results indicated that "family" was the dominant source of belongingness for both males and females, followed by "friendships" and "school." Friendships and education were valued more by females than by males. Symbolic items (e.g., relationships, happiness) influenced females' self-identity more than they did males, while males tended to place greater importance on material items (e.g., home, TV, sports equipment). Athletic activities were highly important in males' self-validation process while females were oriented more toward the artistic and creative. General affective attributes (e.g., honesty, respect, thoughtfulness) were similarly valued by males and females as important criteria for self-evaluation. Finally, males were more religious, patriotic, and felt stronger ties to ancestors while females appeared to be more altruistic and placed high importance on social relations.

Researchers are increasingly recognizing the need to include measures of sexual orientation in health studies. However, relatively little attention has been paid to how sexual identity, the cognitive aspect of sexual orientation, is defined and measured. Our study examined the impact of using two separate sexual identity question formats: a three-category question (response options included heterosexual, bisexual, or lesbian/gay), and a similar question with five response options (only lesbian/gay, mostly lesbian/gay, bisexual, mostly heterosexual, only heterosexual). A large probability-based sample of undergraduate university students was surveyed and a randomly selected subsample of participants was asked both sexual identity questions. Approximately one-third of students who identified as bisexual based on the three-category sexual identity measure chose "mostly heterosexual" or "mostly lesbian/gay" on the five-category measure. In addition to comparing sample proportions of lesbian/gay, bisexual, or heterosexual participants based on the two question formats, rates of alcohol and other drug use were also examined among the participants. Substance use outcomes among the sexual minority subgroups differed based on the sexual identity question format used: bisexual participants showed greater risk of substance use in analyses using the three-category measure whereas "mostly heterosexual" participants were at greater risk when data were analyzed using the five-category measure. Study results have important implications for the study of sexual identity, as well as whether and how to recode responses to questions related to sexual identity.

Self-rated health appraisal as cultural and identity process: African American elders' health and evaluative rationales.

PubMed

McMullen, Carmit K; Luborsky, Mark R

2006-08-01

We explored self-rated health by using a meaning-centered theoretical foundation. Self-appraisals, such as self-rated health, reflect a cultural process of identity formation, whereby identities are multiple, simultaneously individual and collective, and produced by specific historical formations. Anthropological research in Philadelphia determined (a) how African American elders appraise their health, and (b) how health evaluations reflect cultural and historical experiences within a community. We interviewed and observed 35 adults aged 65 to 80, stratified by gender and self-rated health. We validated theme analysis of focused interview questions against the larger data set of field notes and transcripts. Health appraisal reflected a complex process of adaptation and identity. Criteria for health included: independent functioning, physical condition, control and responsibility for health, and overall feeling. Evaluative rationales that shaped health appraisals were comparisons, restricted possibilities for self-evaluation, and ways of handling adversity. Evaluative rationales mitigated undesirable health identities (including low self-reported health) and provided mechanisms for claiming desired health identities despite adversity. Describing the criteria and evaluative rationales underlying self-appraisals of health extends current understandings of self-rated health and illustrates the sociohistorical context of individual assessments of well-being.

The comparative recall of Google Scholar versus PubMed in identical searches for biomedical systematic reviews: a review of searches used in systematic reviews.

The usefulness of Google Scholar (GS) as a bibliographic database for biomedical systematic review (SR) searching is a subject of current interest and debate in research circles. Recent research has suggested GS might even be used alone in SR searching. This assertion is challenged here by testing whether GS can locate all studies included in 21 previously published SRs. Second, it examines the recall of GS, taking into account the maximum number of items that can be viewed, and tests whether more complete searches created by an information specialist will improve recall compared to the searches used in the 21 published SRs. The authors identified 21 biomedical SRs that had used GS and PubMed as information sources and reported their use of identical, reproducible search strategies in both databases. These search strategies were rerun in GS and PubMed, and analyzed as to their coverage and recall. Efforts were made to improve searches that underperformed in each database. GS' overall coverage was higher than PubMed (98% versus 91%) and overall recall is higher in GS: 80% of the references included in the 21 SRs were returned by the original searches in GS versus 68% in PubMed. Only 72% of the included references could be used as they were listed among the first 1,000 hits (the maximum number shown). Practical precision (the number of included references retrieved in the first 1,000, divided by 1,000) was on average 1.9%, which is only slightly lower than in other published SRs. Improving searches with the lowest recall resulted in an increase in recall from 48% to 66% in GS and, in PubMed, from 60% to 85%. Although its coverage and precision are acceptable, GS, because of its incomplete recall, should not be used as a single source in SR searching. A specialized, curated medical database such as PubMed provides experienced searchers with tools and functionality that help improve recall, and numerous options in order to optimize precision. Searches for SRs should be performed by experienced searchers creating searches that maximize recall for as many databases as deemed necessary by the search expert.

2012-10-01

A novel two-dimensional circular photonic crystal (CPC) structure with a sectorial opening for shaping the beam of light sources was designed and investigated. When combined with light sources, the structure acts like an antenna emitting a directional beam which could be advantageously used in several nanophotonic applications. Using the two-dimensional finite-difference time-domain (2D FDTD) method, we examined the effects of geometrical parameters of the structure on the directional and transmission properties of emitted radiation. Further, we examined the transmitting and receiving properties of a pair of identical structures as a function of distance between them.

Genetic Characterization of Soybean Rhizobia in Paraguay†

The soybean is an exotic plant introduced in Paraguay in this century; commercial cropping expanded after the 1970s. Inoculation is practiced in just 15 to 20% of the cropping areas, but root nodulation occurs in most sites where soybeans grow. Little is known about rhizobial diversity in South America, and no study has been performed in Paraguay until this time. Therefore, in this study, the molecular characterization of 78 rhizobial isolates from soybean root nodules, collected under field conditions in 16 sites located in the two main producing states, Alto Paraná and Itapúa, was undertaken. A high level of genetic diversity was detected by an ERIC-REP-PCR analysis, with the majority of the isolates representing unique strains. Most of the 58 isolates characterized by slow growth and alkaline reactions in a medium containing mannitol as a carbon source were clustered with strains representative of the Bradyrhizobium japonicum and Bradyrhizobium elkanii species, and the 16S ribosomal DNA (rDNA) sequences of 5 of those isolates confirmed the species identities. However, slow growers were highly polymorphic in relation to the reference strains, including five carried in commercial inoculants in neighboring countries, thus indicating that the Paraguayan isolates might represent native bradyrhizobia. Twenty isolates highly polymorphic in the ERIC-REP-PCR profiles were characterized by fast growth and acid reactions in vitro, and two of them showed high 16S rDNA identities with Rhizobium genomic species Q. However, two other fast growers showed high 16S rDNA identity with Agrobacterium spp., and both of these strains established efficient symbioses with soybean plants. PMID:11055970

Abide with me: religious group identification among older adults promotes health and well-being by maintaining multiple group memberships.

Aging is associated with deterioration in health and well-being, but previous research suggests that this can be attenuated by maintaining group memberships and the valued social identities associated with them. In this regard, religious identification may be especially beneficial in helping individuals withstand the challenges of aging, partly because religious identity serves as a basis for a wider social network of other group memberships. This paper aims to examine relationships between religion (identification and group membership) and well-being among older adults. The contribution of having and maintaining multiple group memberships in mediating these relationships is assessed, and also compared to patterns associated with other group memberships (social and exercise). Study 1 (N = 42) surveyed older adults living in residential care homes in Canada, who completed measures of religious identity, other group memberships, and depression. Study 2 (N = 7021) longitudinally assessed older adults in the UK on similar measures, but with the addition of perceived physical health. In Study 1, religious identification was associated with fewer depressive symptoms, and membership in multiple groups mediated that relationship. However, no relationships between social or exercise groups and mental health were evident. Study 2 replicated these patterns, but additionally, maintaining multiple group memberships over time partially mediated the relationship between religious group membership and physical health. Together these findings suggest that religious social networks are an especially valuable source of social capital among older adults, supporting well-being directly and by promoting additional group memberships (including those that are non-religious).

Pathogenic Escherichia coli Found in Sewage Treatment Plants and Environmental Waters

2012-01-01

We previously demonstrated that some Escherichia coli strains with uropathogenic properties survived treatment stages of sewage treatment plants (STPs), suggesting that they may be released into the environment. We investigated the presence of such strains in the surrounding environmental waters of four STPs from which these persistent strains were isolated. In all, 264 E. coli isolates were collected from 129 receiving water sites in a 20-km radius surrounding STPs. We also included 93 E. coli strains collected from 18 animal species for comparison. Isolates were typed using a high-resolution biochemical fingerprinting method (the PhPlate system), and grouped into common (C) types. One hundred forty-seven (56%) environmental isolates were identical to strains found in STPs' final effluents. Of these, 140 (95%) carried virulence genes (VGs) associated with intestinal pathogenic E. coli (IPEC) or uropathogenic E. coli (UPEC) and were found in a variety of sites within areas sampled. Of the remaining 117 environmental strains not identical to STP strains, 105 belonged to 18 C types and 102 of them carried VGs found among IPEC or UPEC strains. These strains belonged mainly to phylogenetic groups A (A0 and A1) and B1 and to a lesser extent B22, B23, D1, and D2. Eight of 18 environmental C types, comprising 50 isolates, were also identical to bird strains. The presence of a high percentage of environmental E. coli in waters near STPs carrying VGs associated with IPEC and UPEC suggests that they may have derived from STP effluents and other nonpoint sources.

Nuclear inheritance and genetic exchange without meiosis in the binucleate parasite Giardia intestinalis

2012-01-01

The protozoan parasite Giardia intestinalis (also known as Giardia lamblia) is a major waterborne pathogen. During its life cycle, Giardia alternates between the actively growing trophozoite, which has two diploid nuclei with low levels of allelic heterozygosity, and the infectious cyst, which has four nuclei and a tough outer wall. Although the formation of the cyst wall has been studied extensively, we still lack basic knowledge about many fundamental aspects of the cyst, including the sources of the four nuclei and their distribution during the transformation from cyst into trophozoite. In this study, we tracked the identities of the nuclei in the trophozoite and cyst using integrated nuclear markers and immunofluorescence staining. We demonstrate that the cyst is formed from a single trophozoite by a mitotic division without cytokinesis and not by the fusion of two trophozoites. During excystation, the cell completes cytokinesis to form two daughter trophozoites. The non-identical nuclear pairs derived from the parent trophozoite remain associated in the cyst and are distributed to daughter cells during excystation as pairs. Thus, nuclear sorting (such that each daughter cell receives a pair of identical nuclei) does not appear to be a mechanism by which Giardia reduces heterozygosity between its nuclei. Rather, we show that the cyst nuclei exchange chromosomal genetic material, perhaps as a way to reduce heterozygosity in the absence of meiosis and sex, which have not been described in Giardia. These results shed light on fundamental aspects of the Giardia life cycle and have implications for our understanding of the population genetics and cell biology of this binucleate parasite.

To explore how academic physicians perform social and professional identities and how their personal experiences inform professional identity formation. Semi-structured interviews and observations were conducted with 25 academic physicians of diverse gender and racial/ethnic backgrounds at the University of Utah School of Medicine from 2015-2016. Interviews explored the domains of social identity, professional identity, and relationships with patients and colleagues. Patient interactions were observed. Interviews and observations were audio-recorded, transcribed, and analyzed using grounded theory. Three major themes emerged: physicians' descriptions of identity differed based on social identities, as women and racially/ethnically minoritized participants linked their gender and racial/ethnic identities, respectively, to their professional roles more than men and White, non-Latino/a participants; physicians' descriptions of professional practice differed based on social identities, as participants who associated professional practices with personal experiences often drew from events connected to their minoritized identities; and physicians' interactions with patients corresponded to their self-described actions. Professional identity formation is an ongoing process and the negotiation of personal experiences is integral to this process. This negotiation may be more complex for physicians with minoritized identities. Implications for medical education include providing students, trainees, and practicing physicians with intentional opportunities for reflection and instruction on connecting personal experiences and professional practice.

A 46-year-old woman presented with endometrial cells on a pap smear and underwent endometrial curettage. The specimen revealed secretory endometrium and a possible endometrial polyp. In addition, a single 4 mm fragment of well-differentiated adenocarcinoma was found. Tissue identity DNA genotyping was performed and the adenocarcinoma tissue fragment showed a drastically different allelic pattern from that of the background endometrium. To confirm tissue contamination, genotyping of three other tumor specimens-probable sources for a contaminant-was performed but failed to identify a match. Without confirmation of contamination, a second endometrial curettage was obtained from the patient, in which similar adenocarcinoma tissue was once again found. Further workup demonstrated that the patient had a microsatellite unstable (MSI) endometrial adenocarcinoma by immunohistochemistry and molecular testing. The patient subsequently underwent staging surgery, which revealed an early-stage, well-differentiated endometrioid adenocarcinoma. This case study illustrates an uncommon, yet important caveat of tissue identity testing by DNA genotyping, where MSI instability can significantly alter the allelic pattern of DNA polymorphisms in the tumor genome, leading to erroneous conclusion regarding the tissue identity. Awareness of this phenomenon is crucial for a molecular pathologist to avoid interpretation errors of tissue identity testing in a cancer diagnostic workup.

Middle-aged and older gay men experience higher rates of depression and anxiety compared to their heterosexual counterparts, with internalized homonegativity and sexual identity concealment known to be major stress-related contributors. This study examined the prospective effect of different types and sources of social support on internalized homonegativity and sexual identity concealment experienced among middle-aged and older gay men. A longitudinal survey involving two waves of data collection separated by 12 months was conducted among a cohort of 186 gay-identified men aged 40 years and older. Two types of social support were found to be important. Greater baseline tangible or practical support independently predicted lower internalized homonegativity at 12-month follow-up, while greater baseline emotional or psychological support independently predicted a lower tendency toward sexual identity concealment at 12-month follow-up. Greater baseline support from community or government agencies, such as health services and support organizations, predicted higher internalized homonegativity at 12-month follow-up. These findings suggest that tangible and emotional support may be beneficial in reducing internalized homonegativity and sexual identity concealment among middle-aged and older gay men. Ensuring that services provide environments that do not compound the stressful impact of stigma also appears to be important.

Children of homosexuals more apt to be homosexuals? A reply to Morrison and to Cameron based on an examination of multiple sources of data.

Schumm, Walter R

2010-11-01

Ten narrative studies involving family histories of 262 children of gay fathers and lesbian mothers were evaluated statistically in response to Morrison's (2007) concerns about Cameron's (2006) research that had involved three narrative studies. Despite numerous attempts to bias the results in favour of the null hypothesis and allowing for up to 20 (of 63, 32%) coding errors, Cameron's (2006) hypothesis that gay and lesbian parents would be more likely to have gay, lesbian, bisexual or unsure (of sexual orientation) sons and daughters was confirmed. Percentages of children of gay and lesbian parents who adopted non-heterosexual identities ranged between 16% and 57%, with odds ratios of 1.7 to 12.1, depending on the mix of child and parent genders. Daughters of lesbian mothers were most likely (33% to 57%; odds ratios from 4.5 to 12.1) to report non-heterosexual identities. Data from ethnographic sources and from previous studies on gay and lesbian parenting were re-examined and found to support the hypothesis that social and parental influences may influence the expression of non-heterosexual identities and/or behaviour. Thus, evidence is presented from three different sources, contrary to most previous scientific opinion, even most previous scientific consensus, that suggests intergenerational transfer of sexual orientation can occur at statistically significant and substantial rates, especially for female parents or female children. In some analyses for sons, intergenerational transfer was not significant. Further research is needed with respect to pathways by which intergenerational transfer of sexual orientation may occur. The results confirm an evolving tendency among scholars to cite the possibility of some degree of intergenerational crossover of sexual orientation.

In this paper, an integrated multi-source energy harvester (IMSEH) employing a special shaped cantilever beam and a piezoelectric transducer to convert vibration and magnetic field energy into electrical energy is presented. The electric output performance of the proposed IMSEH has been investigated. Compared to a traditional multi-source energy harvester (MSEH) or single source energy harvester (SSEH), the proposed IMSEH can simultaneously harvest vibration and magnetic field energy with an integrated structure and the electric output is greatly improved. When other conditions keep identical, the IMSEH can obtain high voltage of 12.8V. Remarkably, the proposed IMSEHs have great potential for its application in wireless sensor network.

Preferred Names, Preferred Pronouns, and Gender Identity in the Electronic Medical Record and Laboratory Information System: Is Pathology Ready?

Electronic medical records (EMRs) and laboratory information systems (LISs) commonly utilize patient identifiers such as legal name, sex, medical record number, and date of birth. There have been recommendations from some EMR working groups (e.g., the World Professional Association for Transgender Health) to include preferred name, pronoun preference, assigned sex at birth, and gender identity in the EMR. These practices are currently uncommon in the United States. There has been little published on the potential impact of these changes on pathology and LISs. We review the available literature and guidelines on the use of preferred name and gender identity on pathology, including data on changes in laboratory testing following gender transition treatments. We also describe pathology and clinical laboratory challenges in the implementation of preferred name at our institution. Preferred name, pronoun preference, and gender identity have the most immediate impact on the areas of pathology with direct patient contact such as phlebotomy and transfusion medicine, both in terms of interaction with patients and policies for patient identification. Gender identity affects the regulation and policies within transfusion medicine including blood donor risk assessment and eligibility. There are limited studies on the impact of gender transition treatments on laboratory tests, but multiple studies have demonstrated complex changes in chemistry and hematology tests. A broader challenge is that, even as EMRs add functionality, pathology computer systems (e.g., LIS, middleware, reference laboratory, and outreach interfaces) may not have functionality to store or display preferred name and gender identity. Implementation of preferred name, pronoun preference, and gender identity presents multiple challenges and opportunities for pathology.

These practices are currently uncommon in the United States. There has been little published on the potential impact of these changes on pathology and LISs. Methods: We review the available literature and guidelines on the use of preferred name and gender identity on pathology, including data on changes in laboratory testing following gender transition treatments. We also describe pathology and clinical laboratory challenges in the implementation of preferred name at our institution. Results: Preferred name, pronoun preference, and gender identity have the most immediate impact on the areas of pathology with direct patient contact such as phlebotomy and transfusion medicine, both in terms of interaction with patients and policies for patient identification. Gender identity affects the regulation and policies within transfusion medicine including blood donor risk assessment and eligibility. There are limited studies on the impact of gender transition treatments on laboratory tests, but multiple studies have demonstrated complex changes in chemistry and hematology tests. A broader challenge is that, even as EMRs add functionality, pathology computer systems (e.g., LIS, middleware, reference laboratory, and outreach interfaces) may not have functionality to store or display preferred name and gender identity. Conclusions: Implementation of preferred name, pronoun preference, and gender identity presents multiple challenges and opportunities for pathology. PMID:29114436

Little Scientists: Identity, Self-Efficacy, and Attitude Toward Science in a Girls' Science Camp

Todd, Brandy

Underrepresentation of women and minorities in the science, technology, and engineering (STEM) fields is a perennial concern for researchers and policy-makers. Many causes of this problem have been identified. Less is known about what constitutes effective methods for increasing women's participation in STEM. This study examines the role that identity formation plays in encouraging girls to pursue STEM education and careers utilizing data from a cohort-based, informal science enrichment program that targets middle-school-aged girls. A Mixed-methods design was employed to examine girls' science interests, efficacy, attitudes, and identity---referred to as affinities. Quantitative data were collected before and after program participation using science affinity scales. Qualitative data included observations, focus groups, and individual interviews. This study builds on past research conducted on the same program. The study is presented in three components: fidelity of implementation, participant affinities, and science identity theory building. Quantitative and qualitative measures reveal that the program was implemented with high fidelity. Participants had high initial affinities for science as compared to a contrast group. Analysis of qualitative data of science affinities revealed several themes in girls' attitudes, experiences, and intentions toward science. Emergent themes discussed include girls' preferences and interests in science, gender and science efficacy, attitudes toward science, and elements of science identities. Archetypes of emergent science identities developed in this study (expert, experimenter, and inventor) inform different ways in which girls engage with and envision science study and careers. Implications for best practice in fostering science engagement and identities in middle-school-aged girls include the importance of hands-on science activities, the need for enthusiastic relatable role models, and an emphasis on deep understanding of scientific principles.

Like specialization, identity offers a way for differentiating and understanding recreationists and for gaining insight into the question of participant progression in an activity. We examined how identity related to measures of specialization among lapsed and current waterfowl hunters. Lapsed hunters included those who had purchased a Minnesota waterfowl stamp between 2000 and 2004, but not since this time. Current hunters had purchased a 2010 stamp. Results suggested that some waterfowl hunters specialize and progress toward a waterfowl-hunter identity. Others, however, either hunt for years but never specialize and identify as waterfowl hunters, or move toward but do not attain a waterfowl hunter identity. Individuals who achieve a waterfowl hunter identity may also later relinquish this identity. Identification was associated with increased specialization and resistance to change from a preference for waterfowl hunting. Individuals who had relinquished their identity retained social and knowledge-based commitment to waterfowl hunting, whereas attraction and centrality declined.

Goals for improving the quality of care for all Veterans and eliminating health disparities are outlined in the Veterans Health Administration Blueprint for Excellence, but the degree to which disparities in utilization, health outcomes, and quality of care affect Veterans is not well understood. To characterize the research on health care disparities in the Veterans Health Administration by means of a map of the evidence. We conducted a systematic search for research studies published from 2006 to February 2016 in MEDLINE and other data sources. We included studies of Veteran populations that examined disparities in 3 outcome categories: utilization, quality of health care, and patient health. We abstracted data on study design, setting, population, clinical area, outcomes, mediators, and presence of disparity for each outcome category. We grouped the data by population characteristics including race, disability status, mental illness, demographics (age, era of service, rural location, and distance from care), sex identity, socioeconomic status, and homelessness, and created maps illustrating the evidence. We reviewed 4249 citations and abstracted data from 351 studies which met inclusion criteria. Studies examining disparities by race/ethnicity comprised by far the vast majority of the literature, followed by studies examining disparities by sex, and mental health condition. Very few studies examined disparities related to lesbian, gay, bisexual, or transgender identity or homelessness. Disparities findings vary widely by population and outcome. Our evidence maps provide a "lay of the land" and identify important gaps in knowledge about health disparities experienced by different Veteran populations.

Ego identity of adolescent children of alcoholics.

Gavriel-Fried, Belle; Teichman, Meir

2007-01-01

The study examines the issue of ego identity among adolescent sons of alcoholic fathers. Forty-four adolescent sons of alcoholic fathers, age of 15-18, constituted the sample. They were drawn from public alcohol treatment center in Israel. The control group included 60 adolescents none of their parents is known as an alcoholic, sampled from integrative schools in the same neighborhood and matched by age. Ego identity was measured by Tzuriel's "Adolescent Ego Identity Scale" (AEIS). It was hypothesized that adolescent children of alcoholics will show lower scores of ego identity and of its dimensions. The hypothesis was not confirmed. To the contrary, adolescent children of alcoholics reported higher scores of "ego identity-total" and of four of the seven ego identity dimensions. One possible explanation is that children of alcoholics are maturing early in age compared to their controls. They have developed different coping strategies that facilitate creating a more "stable" ego identity compared to their peers. Another explanation is that children of alcoholics apply defense mechanisms that enhance the development of an "adaptive self."

2013-01-01

This study analyzed data from a large statewide sample of Native American adolescents throughout California to determine whether participation in cultural practices was associated with stronger ethnic identity. The Multigroup Ethnic Identity Measure (MEIM) scale was used to measure the ethnic identity of 945 Native American adolescents (416 male, 529 female) aged 13 – 19 across California. Respondents who participated in cultural activities including pow-wows, sweat lodge, drum group and roundhouse dance reported significantly higher Native American ethnic identity than their counterparts who did not take part in cultural activities. The association between cultural activities and ethnic identity was only significant among urban youth and not among reservation youth. Higher grades in school were associated with ethnic identity among females but not among males. Findings from this study show a strong association between cultural activities and traditional practices with tribal enculturation among Native American youth in California. Cultural-based practices to enhance Native identity could be useful to improve mental and behavioral health among Native American youth. PMID:22400467

Aggregating thermal generators with identical characteristics (e.g., minimum/maximum power output, minimum up/down-time, and cost curves) into a single unit reduces redundancy in the search space induced by both exact symmetry (permutations of generator schedules) and certain classes of mutually non-dominated solutions.

Several commonly used statistical methods for fingerprint identification in microbial source tracking (MST) were examined to assess the effectiveness of pattern-matching algorithms to correctly identify sources. Although numerous statistical methods have been employed for source identification, no widespread consensus exists as to which is most appropriate. A large-scale comparison of several MST methods, using identical fecal sources, presented a unique opportunity to assess the utility of several popular statistical methods. These included discriminant analysis, nearest neighbour analysis, maximum similarity and average similarity, along with several measures of distance or similarity. Threshold criteria for excluding uncertain or poorly matched isolates from final analysis were also examined for their ability to reduce false positives and increase prediction success. Six independent libraries used in the study were constructed from indicator bacteria isolated from fecal materials of humans, seagulls, cows and dogs. Three of these libraries were constructed using the rep-PCR technique and three relied on antibiotic resistance analysis (ARA). Five of the libraries were constructed using Escherichia coli and one using Enterococcus spp. (ARA). Overall, the outcome of this study suggests a high degree of variability across statistical methods. Despite large differences in correct classification rates among the statistical methods, no single statistical approach emerged as superior. Thresholds failed to consistently increase rates of correct classification and improvement was often associated with substantial effective sample size reduction. Recommendations are provided to aid in selecting appropriate analyses for these types of data.

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

Contaminated water is one of the main sources of norovirus (NoV) gastroenteritis outbreaks globally. Waterborne NoV outbreaks are infrequently attributed to GII.4 NoV. In September 2009, a NoV outbreak affected a small school in Guangdong Province, China. Epidemiological investigations indicated that household use water, supplied by a well, was the probable source (relative risk 1·9). NoV nucleic acid material in concentrated well-water samples was detected using real-time RT-PCR. Nucleotide sequences of NoV extracted from diarrhoea and well-water specimens were identical and had the greatest sequence identity to corresponding sequences from the epidemic strain GII.4-2006b. Our report documents the first laboratory-confirmed waterborne outbreak caused by GII.4 NoV genotype in China. Our investigations indicate that well water, intended exclusively for household use but not for consumption, caused this outbreak. The results of this report serve as a reminder that private well water intended for household use should be tested for NoV.

2015-03-01

Countless proteomics data processing algorithms have been proposed, yet few have been critically evaluated due to lack of labeled data (data with known identities and quantities). Although labeling techniques exist, they are limited in terms of confidence and accuracy. In silico simulators have recently been used to create complex data with known identities and quantities. We propose Java Mass Spectrometry Simulator (JAMSS): a fast, self-contained in silico simulator capable of generating simulated MS and LC-MS runs while providing meta information on the provenance of each generated signal. JAMSS improves upon previous in silico simulators in terms of its ease to install, minimal parameters, graphical user interface, multithreading capability, retention time shift model and reproducibility. The simulator creates mzML 1.1.0. It is open source software licensed under the GPLv3. The software and source are available at https://github.com/optimusmoose/JAMSS. © The Author 2014.

Gender identity felt pressure is negatively associated with adjustment indices, including self-esteem, among children and early adolescents, and both gender and ethnic-racial identity felt pressure are negatively associated with self-esteem among young adults. This study explored the longitudinal associations between gender identity and ethnic-racial identity felt pressure from family and peers to behave in either gender or race/ethnic-accordant ways, and self-esteem among a sample of 750 (49.2% female) African American (n = 194) and Latino/a youth (n = 556) (M = 12.10 years, SD = .97 years). For African Americans, the results revealed significant negative longitudinal associations between (a) ethnic-racial identity felt pressure from family at Time 1 and self-esteem at Time 2 and (b) ethnic-racial identity felt pressure from peers at Time 1 and self-esteem at Time 2, controlling for self-esteem at Time 1. These associations were not found among Latinos/as, nor were associations found between gender identity felt pressure from peers or family and self-esteem. The findings are discussed by drawing on the gender identity and ethnic-racial identity literatures.

Trajectories of Identity Formation Modes and Their Personality Context in Adolescence.

Topolewska-Siedzik, Ewa; Cieciuch, Jan

2018-04-01

Identity formation is a dynamic process during adolescence. Trajectories of identity formation were assessed longitudinally in early and middle adolescents, taking into account the personality underpinnings of this process. Identity formation was conceptualized according to the circumplex of identity formation modes. The model distinguishes basic modes rooted in Marcia's categories of exploration and commitment. Plasticity and stability, the two higher order Big Five meta-traits, were used to assess personality underpinnings. This study includes five measurement waves over 1.5 years and involves 1,839 Polish participants; 914 early adolescents (53.9% girls) and 925 middle adolescents (63.8% girls). The results suggest that (1) the four identity formation modes change dynamically, showing linear and curvilinear growth and that (2) identity formation mode trajectories are more dynamic in middle adolescence than in early adolescence. The results also showed that, in the conditional model, (3) the higher-order personality factors and gender affect the growth factors of identity formation modes. Overall, trajectories of identity formation modes are more linear during early adolescence and more curvilinear during middle adolescence. The initial levels in identity trajectories are influenced by the personality metatraits but only plasticity is related to change among early adolescents.

"I provide the pleasure, I control it": sexual pleasure and "bottom" identity constructs amongst gay youth in a Stepping Stones workshop.

PubMed

Kiguwa, Peace

2015-11-01

This paper explores the meanings attached to gay sexuality through the self-labelling practices of a group of young gay-identified students in focus group and individual interviews in Johannesburg, South Africa. These meanings include constructs of the dynamics surrounding safe sex negotiation and risk related to "top-bottom" subject positioning as well as the erotics of power and desire that are imbued in these practices and positioning. Using performativity theory as a theoretical tool of analysis, I argue that constructs of "top-bottom" subjectivities can be seen to meet certain erotic needs for LGBTI youth, including reasons related to physical safety for LGBTI people living in dangerous spaces. The performance of "bottom" identities in sexual intimacy and behaviour is further deployed in the expression and performance of power that the participants construct as erotic. The implications for sexual health intervention include understanding the gendered performance influences of sexual behaviour including safe sex, exploring creative ways that practices of sexual health can be engaged with this population group in a way that accommodates the erotic pleasure interfaced with sexual identity identifications and performances of "bottom" identities.

Listening to their voices: Exploring mathematics-science identity development of African American males in an urban school community

NASA Astrophysics Data System (ADS)

Wilson, Kimi Leemar

National data continues to show an underrepresentation of African American males pursuing science, technology, engineering and mathematics (STEM) majors, careers and professions in the United States. Whites and Asian Americans are continuously positioned as the face of STEM education and participation. And while research has provided ways to support mathematics and science learning for African American males, there still remains a gap in understanding how their formed mathematics-science identities in K-12 public schooling influences STEM participation. The research undertaken in this study explores this gap, and uses an integrative identity framework to understand mathematics-science identity development which goes beyond personal identity, and explores the relational, collective and material components of identity. Specifically, this research seeks to answer the following research questions: What are the shared lived experiences that exist between a group of African American male students developing a mathematics-science identity, and how these shared lived experiences shape their mathematics-science identity development? Therefore, by analyzing African American males lived experiences employing an integrative identity framework fosters a greater understanding of how mathematics-science identity is formed in K-12 public schools, which impacts STEM education and participation. The high school aged youth featured in this study consist of four African American males, who live in a moderate size city in California. Data for this study consists of observations, phenomenological interviews, and policy document analysis that took place over six months. Data has been analyzed to describe and interpret the young men's mathematics and science experiences, as revealed in their K-12 public school education. This inquiry sought to make meaning of how African American males experience mathematics and science teaching and learning within K-12 public schooling and how these experiences impact mathematics-science identity development. The goal of the study seeks to inform educational, psychological and sociological theory about how urban adolescent African American males understand, develop and make use of their mathematics and science knowledge. Finally, this work seeks to inform mathematics and science educational research to include identity theory, beyond a personal or individual identity perspective, but also to include relational, collective, and material identity components to understand how the culture of mathematics and science within and outside of K-12 public schooling impacts African American males in an endeavor to become learners of mathematics and science.

Discovery of a novel retrovirus sequence in an Australian native rodent (Melomys burtoni): a putative link between gibbon ape leukemia virus and koala retrovirus.

PubMed

Simmons, Greg; Clarke, Daniel; McKee, Jeff; Young, Paul; Meers, Joanne

2014-01-01

Gibbon ape leukaemia virus (GALV) and koala retrovirus (KoRV) share a remarkably close sequence identity despite the fact that they occur in distantly related mammals on different continents. It has previously been suggested that infection of their respective hosts may have occurred as a result of a species jump from another, as yet unidentified vertebrate host. To investigate possible sources of these retroviruses in the Australian context, DNA samples were obtained from 42 vertebrate species and screened using PCR in order to detect proviral sequences closely related to KoRV and GALV. Four proviral partial sequences totalling 2880 bases which share a strong similarity with KoRV and GALV were detected in DNA from a native Australian rodent, the grassland melomys, Melomys burtoni. We have designated this novel gammaretrovirus Melomys burtoni retrovirus (MbRV). The concatenated nucleotide sequence of MbRV shares 93% identity with the corresponding sequence from GALV-SEATO and 83% identity with KoRV. The geographic ranges of the grassland melomys and of the koala partially overlap. Thus a species jump by MbRV from melomys to koalas is conceivable. However the genus Melomys does not occur in mainland South East Asia and so it appears most likely that another as yet unidentified host was the source of GALV.

A world-wide effort is now being pursued towards the development of flavors and fragrances (F&F) production independently from traditional sources, as well as autonomously from depleting fossil fuel supplies. Biotechnological production of F&F by microbes has emerged as a vivid solution to the current market limitations. Amongst a wide variety of fragrant chemicals, 2-PE is of significant interest to both scientific and industrial community. Although the general overview of the 2-PE synthesis pathway is commonly known, involvement of particular molecular identities in this pathway has not been elucidated in Yarrowia lipolytica to date. The aim of this study was mapping molecular identities involved in 2-PE synthesis in Y. lipolytica. To acquire a comprehensive landscape of the proteins that are directly and indirectly involved in L-Phe degradation and 2-PE synthesis, we took advantage of comprehensibility and sensitivity of high-throughput LC-MS/MS-quantitative analysis. Amongst a number of proteins involved in amino acid turnover and the central carbon metabolism, enzymes involved in L-Phe conversion to 2-PE have been identified. Results on yeast-to-hyphae transition in relation to the character of the provided nitrogen source have been presented. © FEMS 2015. All rights reserved.
