  1. The postmodern crisis and the loss of stable identity

    Full Text Available The paper proves the assumption that being a worldview of the information society postmodernism simultaneously reverberates its problems, among which is blurring personal identity. The most vulnerable part of the postmodern ideology is the implicit inability to construct steady architecture of identification. This is hampered by specific ideas related to the fundamental principle of postmodernism, i.e. pluralism leading to relativism and the loss of sustainable landmarks. Applying the pluralism principle to the full may result in unlimited choice production, which should not be considered the achievement of the information society and postmodern culture, but its main problem. The social political consequences of tolerance issues and the equivalence of opinions, attitudes and values are discussed. Lack of preferred self-identification vectors reduces the motivation for the individual to develop a stable personal identity. If no paradigm in terms of the truth can claim a given status disputes over claims of significance turn into controversies over power, thereby generating social Darwinism. The principle of pluralism actually legitimizes radical ideologies, whose extreme form is terrorism put in the mosaic and multicultural postmodern world occurs to be one of many sociocultural paradigms. Exactly the identity crisis in the conditions of mass distribution of both military and information technologies is considered the main cause of radicalism as the result of finding pathological forms of cognitive personal identity. Social cultural and worldview crises of the information society are becoming the main cause for producing endurable and irregular forms of personal identity architecture.

    An effective inquiry-oriented science teacher possesses more than the skills of teaching through investigation. They must address philosophies, and ways of interacting as a member of a group of educators who value and practice science through inquiry. Professional development opportunities can support inquiry identity development, but most often they address teaching practices from limited cognitive perspectives, leaving unexplored the shifts in identity that may accompany teachers along their journey in becoming skilled in inquiry-oriented instruction. In this forum article, we envision Victoria Deneroff's argument that "professional development could be designed to facilitate reflexive transformation of identity within professional learning environments" (2013, p. 33). Instructional coaching, cogenerative dialogues, and online professional communities are discussed as ways to promote inquiry identity formation and collaboration in ways that empower and deepen science teachers' conversations related to personal and professional efficacy in the service of improved science teaching and learning.

  4. Citizen Science: Opportunities for Girls' Development of Science Identity

    Science.gov (United States)

    Brien, Sinead Carroll

    Many students in the United States, particularly girls, have lost interest in science by the time they reach high school and do not pursue higher degrees or careers in science. Several science education researchers have found that the ways in which youth see themselves and position themselves in relation to science can influence whether they pursue science studies and careers. I suggest that participation in a citizen science program, which I define as a program in which girls interact with professional scientists and collect data that contributes to scientific research, could contribute to changing girls' perceptions of science and scientists, and promote their science identity work. I refer to science identity as self-recognition and recognition by others that one thinks scientifically and does scientific work. I examined a case study to document and analyze the relationship between girls' participation in a summer citizen science project and their development of science identity. I observed six girls between the ages of 16 and 18 during the Milkweed and Monarch Project, taking field notes on focal girls' interactions with other youth, adults, and the scientist, conducted highly-structured interviews both pre-and post- girls' program participation, and interviewed the project scientist and educator. I qualitatively analyzed field notes and interview responses for themes in girls' discussion of what it meant to think scientifically, roles they took on, and how they recognized themselves as thinking scientifically. I found that girls who saw themselves as thinking scientifically during the program seemed to demonstrate shifts in their science identity. The aspects of the citizen science program that seemed to most influence shifts in these girls' science identities were 1) the framing of the project work as "real science, 2) that it involved ecological field work, and 3) that it created a culture that valued data and scientific work. However, some of the girls only

  8. Prison Nursing: Formation of a Stable Professional Identity.

    Science.gov (United States)

    Choudhry, Khurshid; Armstrong, David; Dregan, Alexandru

    The aim of this study was to analyze how working within prison environments can influence the self-identity and professional identity of nurses. The prison environment can be a difficult environment for nurses to deliver care within, with nurses having to carry out activities that seem to go against their professional role, while at the same time providing care to prisoners who have greater health needs than the general population. There is a lack of theoretical consideration of how prison nurses carry out their role in the face of such challenges. This study used a review of literature published over the last 11 years exploring nurses' beliefs, thoughts, and feelings toward delivering care within prison environment. With time, nurses working within prison environments develop specific skills to be able to deliver appropriate care to their patients. These skills include adapting to both the prison environment and the prison culture. Ultimately, adaptations lead to a change in identity allowing nurses to work effectively within prison. Providers of prison healthcare should ensure that induction (orientation) processes for new nurses are designed to address specific challenges that nurses face including the potential for cognitive dissonance. They should ensure that nurses receive training to develop and acquire the skills highlighted in this review. Ensuring that this training is in place may increase nurse retention.

  12. Exploring the positional identities of high school science teachers

    Science.gov (United States)

    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.

    Chaffee, Rachel L.

    This dissertation study contributes to the research on filmmaking and identity development by exploring the ways that film production provided unique opportunities for a team of four girls to engage in science, to develop identities in science, and to see and understand science differently. Using social practice, identity, and feminist theory and New Literacies Studies as a theoretical lens and grounded theory and multimodality as analytic frameworks, I present findings that suggest that girls in this study authored identities and communicated and represented science in and through film in ways that drew on their social, cultural, and embodied resources and the material resources of the after-school science club. Findings from this study highlight the affordances of filmmaking as a venue for engaging in the disciplinary practices of science and for accessing and authoring identities in science.

    2014-12-01

    Ludwik Fleck, the Polish philosopher of science, maintained that scientific discovery is influenced by social, political, historical, psychological, and personal factors. The determinants of Freud's Jewish identity are examined from this Fleckian perspective, as is the impact of that complex identity on his creation of psychoanalysis as a science. Three strands contributing to his Jewish identity are identified and explored: his commitment to the ideal of Bildung, the anti-Semitism of the times, and his "godlessness." Finally, the question is addressed of what it means that psychoanalysis was founded by a Jew. For Freud, psychoanalysis was a kind of liberation philosophy, an attempt to break free of his ethnic and religious inheritance. Yet it represented at the same time his ineradicable relationship with that inheritance. It encapsulated both the ambivalence of his Jewish identity and the creativity of his efforts to resolve it. © 2014 by the American Psychoanalytic Association.

    2015-08-01

    The CILogon-HA project extended the existing open source CILogon service (initially developed with funding from the National Science Foundation) to provide credentials at multiple levels of assurance to users of DOE facilities for collaborative science. 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) and 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.

  18. 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

    Science education researchers are recognizing the need to consider identity and other sociocultural factors when examining causes of the science achievement gap for African American students. Non-school settings may hold greater promise than formal schooling to promote identities that are conductive to science learning in African Americans. This mixed-methods study explored the relationship between participation in out-of-school-time (OST) science enrichment programs and African American middle and high school students' racial and ethnic identity (RED, social identity as science learners, and achievement. Pre-post questionnaires used a previously validated model of REI combined with an original subscale that was developed to measure social identity as science learners. Case studies of two programs allowed for an analysis of the informal learning setting. The treatment group (N = 36) consisted of African American middle and high school students in five OST science programs, while the control group (N = 54) students were enrolled in science classes in public schools in the mid-Atlantic region. Results of a t-test of independent means indicated that there was no significant difference between the treatment and control group on measures of REI or science identity. However, the treatment group earned significantly higher science grades compared to the control group, and an ANOVA revealed a significant relationship between science identity and the intention to pursue post-secondary science studies. Although not significant, MANOVA results indicated that students who participated in OST programs exhibited gradual increases in RD and science identity over time according to grade level and gender. Follow-up analysis revealed significant relationships between awareness of racism, gender, and length of time in OST programs. The case studies illustrated that a unique community of practice exists within the OST programs. Access to authentic science learning experiences, youth

  1. CILogon: An Integrated Identity and Access Management Platform for Science

    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

  2. Teaching heroics: Identity and ethical imagery in science education

    Science.gov (United States)

    Robeck, Edward C.

    In what follows, I address ways in which science education can influence personal identity and social relationships. I do this through a consideration of ideological implications of science as it is constituted in science education. In this situation, I consider science to be a symbolic--emanating from socially derived meanings. I begin with the premise that any symbol system is permeated with ideological elements. To highlight the ideological elements of science in science education, I use another more explicitly symbolic system as a comparative framework. That system is epic heroism, primarily as Joseph Campbell (1949) describes it in The Hero With A Thousand Faces. The discussion of science education is given a practical grounding using transcripts from the interviews with twenty Grade 10 students and many of their teachers undertaken in the 1993-1994 school year. I used epic heroism as a framework for initiating interpretations of broad themes from the transcripts, but also read the transcripts in relation to aspects of epic heroism, including existing critiques of Campbell's work and heroism more broadly. Specific quotes are included to illustrations of various points. My particular focus here is on ideological elements that can be associated with racism, sexism, and other social relationships that are collectively referred to as relations involving divisive bias. In particular, two themes are discussed extensively. The first is the theme of identity formed through separation, which results in the promotion of reductive and individualistic identities. The second theme has to do with the role of boundary imagery in the formation of relationship, which establishes difference hierarchically. Both of these are pervasive in divisive bias and in the imagery of epic heroism. Ways in which they can pervade practices in science education are also discussed. The central argument of the thesis is that science education, when undertaken through practices that incorporate

    A considerable amount of methane produced during decomposition of landfill waste can be oxidized in landfill cover soil by methane-oxidizing bacteria (methanotrophs) thus reducing greenhouse gas emissions to the atmosphere. The identity of active methanotrophs in Roscommon landfill cover soil, a slightly acidic peat soil, was assessed by DNA-stable isotope probing (SIP). Landfill cover soil slurries were incubated with (13)C-labelled methane and under either nutrient-rich nitrate mineral salt medium or water. The identity of active methanotrophs was revealed by analysis of (13)C-labelled DNA fractions. The diversity of functional genes (pmoA and mmoX) and 16S rRNA genes was analyzed using clone libraries, microarrays and denaturing gradient gel electrophoresis. 16S rRNA gene analysis revealed that the cover soil was mainly dominated by Type II methanotrophs closely related to the genera Methylocella and Methylocapsa and to Methylocystis species. These results were supported by analysis of mmoX genes in (13)C-DNA. Analysis of pmoA gene diversity indicated that a significant proportion of active bacteria were also closely related to the Type I methanotrophs, Methylobacter and Methylomonas species. Environmental conditions in the slightly acidic peat soil from Roscommon landfill cover allow establishment of both Type I and Type II methanotrophs.

  4. Stories we live, identities we build: how are elementary teachers' science identities shaped by their lived experiences?

    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.

  5. Stable coexistence of ecologically identical species: conspecific aggregation via reproductive interference.

    Ruokolainen, Lasse; Hanski, Ilkka

    2016-05-01

    Stable coexistence of ecologically identical species is not possible according to the established ecological theory. Many coexistence mechanisms have been proposed, but they all involve some form of ecological differentiation among the competing species. The aggregation model of coexistence would predict coexistence of identical species if there would be a mechanism that generates spatially aggregated distributions that are not completely correlated among the species. Our aim is to demonstrate that continued dispersal, triggered by reproductive interference between ecologically identical species, is such a mechanism. This study has been motivated by species using ephemeral patchy resources, such as decomposing fruits, fungal sporophores, carrion, and dung. We analyse an individual-based model with sexual reproduction, in which the progeny develops in ephemeral resource patches and the new generation disperses to a new set of patches. We assume spatially restricted dispersal, that patches differ in detectability, and that unmated females continue dispersal. In the model, reproductive interference (males spend some time searching for and/or attempting to mate with heterospecific females) reduces the mating rate of females, especially in the less common species, which leads to increased dispersal and reduces spatial correlation in species' distributions. For a wide range of parameter values, coexisting species show a systematic difference in their relative abundances due to two opposing forces: (1) uncommon species have reduced growth rate (Allee effect), which decreases abundance; (2) an abundance difference between the species reduces interspecific spatial correlation, which in turn reduces interspecific competition and allows the rarer species to persist at low density. Our results demonstrate a new mechanism for coexistence that is not based on ecological differentiation between species. © 2016 The Authors. Journal of Animal Ecology © 2016 British Ecological

  7. Misunderstood misunderstanding: social identities and public uptake of science

    International Nuclear Information System (INIS)

    Wynne, B.

    1992-01-01

    This paper draws general insights into the public reception of scientific knowledge from a case study of Cumbrian sheep farmers' responses to scientific advice about the restrictions introduced after the Chernobyl radioactive fallout. The analysis identifies several substantive factors which influence the credibility of scientific communication. Starting from the now-accepted point that public uptake of science depends primarily upon the trust and credibility public groups are prepared to invest in scientific institutions and representatives, the paper observes that these are contingent upon the social relationships and identities which people feel to be affected by scientific knowledge, which never comes free of social interests or implications. The case study shows laypeople capable of extensive informal reflection upon their social relationships towards scientific experts, and on the epistemological status of their own 'local' knowledge in relation to 'outside' knowledge. Public uptake of science might be improved if scientific institutions expressed an equivalent reflexive discourse in the public domain. (author)

  8. Doing gender/teaching science: A feminist poststructural analysis of middle school science teachers' identity negotiations

    Science.gov (United States)

    Sowell, Scott P.

    This research joins the gender equity conversation within science education by providing a feminist poststructural analysis of teachers' doing gender and teaching science. Feminist poststructuralism is used in recognition of the oppressive nature of dualistic modes of thought, which often reduce reality into a limiting either/or fallacy and can be theoretically constraining as research within any particular field becomes more sophisticated. By uprooting the concept of gendered identity from the unproductive grip of essentialism, and conceptualizing it instead as a shifting 'work in progress,' feminist poststructuralism provides an invigorating theoretical framework from which to conduct inquiries. From a this perspective, the identity of a teacher, as any identity, is not a fixed entity, but rather an unfinished project, swarmed upon by a variety of competing discourses. Situated in a rural middle school in the Florida panhandle, this research explores how numerous discourses compete to define what it means to be a female science teacher. More specifically, the aims of this research are to explore: (a) how the participants negotiated successful gendered identities within science and (b) how this taking up of subject positions crystallized into classroom practices which worked to reproduce and/or challenge commonsense notions of the heteropatriarchal gender dualism as well as the enmeshment of masculinity and science. Findings illustrate a wide array of classroom pedagogical practices, ranging from antioppressive emancipatory constructions of both gender and science to more traditional objectivist constructions that validated the patriarchal status quo. Explicating teacher identity as effects of these pedagogical approaches proved insightful in unveiling notions of resistance, frustration, enthusiasm, and agency as the teachers reflected on their practice.

  9. Schooling girls in a rural community: An examination of female science identity and science career choices

    Science.gov (United States)

    Fowler, Melisa Diane Creasy

    There is a gap in existence between the number of males and females entering science careers. Research has begun to focus largely on how identity impacts the selection of such careers. While much research has been done to examine the factors that impact student identity, little work has been done to examine what happens to female students who have been successful in science in a rural K-12 school once they leave high school and enter the world of academia. Thus, this study examined the following questions: (1) How do three recent female high school graduates from rural K-12 high schools narrate their identity? (2) How do the females narrate their experiences in a rural community and high school in relation to their science identity? (3) What do the participants describe as influencing their academic and career choices as they transition into the life of a college student? This study involved three female participants from a small rural community in a southeastern state. Each female has lived their entire life in the community and has attended only one K-12 school. All three females ranked in the top ten of their senior class and excelled in their science coursework. Additionally, each female elected to attend college locally and to live at home. The study utilized the qualitative methodology of interpretive biography. The researcher used a guided interview protocol with participants which served as the basis for the creation of their narrative biographies. The biographies were then analyzed for emergent themes. Sociocultural theory, identity theory, and critical feminism provided the theoretical frameworks utilized in data analysis. Findings from this study suggested that there were many differing factors influencing the science identity and career choices of the females under study. However, the most salient factor impacting their choices was their desire to remain in their hometown. Directions for future research suggestions involve exploring female students who

In contemporary society the definition and construction of the individual identity is one of the most important problems. Dynamics of choices’ multiplicity, erosion of rigid traditions and norms, they challenge permanent override of individual identity; and this has an impact on the social structure of the society as whole. Most researchers agree ...

  15. Preservice elementary teachers' actual and designated identities as teachers of science and teachers of students

    Science.gov (United States)

    Canipe, Martha Murray

    Preservice elementary teachers often have concerns about teaching science that may stem from a lack of confidence as teachers or their own negative experiences as learners of science. These concerns may lead preservice teachers to avoid teaching science or to teach it in a way that focuses on facts and vocabulary rather than engaging students in the doing of science. Research on teacher identity has suggested that being able to envision oneself as a teacher of science is an important part of becoming a teacher of science. Elementary teachers are generalists and as such rather than identifying themselves as teachers of particular content areas, they may identify more generally as teachers of students. This study examines three preservice teachers' identities as teachers of science and teachers of students and how these identities are enacted in their student teaching classrooms. Using a narrated identity framework, I explore stories told by preservice teachers, mentor teachers, student teaching supervisors, and science methods course instructors about who preservice teachers are as teachers of science and teachers of students. Identities are the stories that are told about who someone is or will become in relation to a particular context. Identities that are enacted are performances of the stories that are an identity. Stories were collected through interviews with each storyteller and in an unmoderated focus group with the three preservice teachers. In addition to sorting stories as being about teachers of science or students, the stories were categorized as being about preservice teachers in the present (actual identities) or in the future (designated identities). The preservice teachers were also observed teaching science lessons in their student teaching placements. These enactments of identities were analyzed in order to identify which aspects of the identity stories were reflected in the way preservice teachers taught their science lessons. I also analyzed the

    This forum paper dialogues with Sheron Mark's A bit of both science and economics: a non-traditional STEM identity narrative. In her paper, she discusses the development of a Science, Technology, Engineering, and Mathematics (STEM) identity by a young African American male during an informal STEM for Social Justice Program. Here, the discussion focuses on Black masculinities, identity formation, and the role of science educators in making STEM fields a welcoming place for young Black men. Drawing from Mark's data and discussion, this paper is a dialogue between science identity possibilities in the United States and in Brazil when we look at the intersections of race, gender, and socioeconomic status. Using the shared colonial past of both countries a connection is established to address race relations within science education. The main argument in this paper is that racism can no longer be denied and dismissed by the science education community worldwide and that intersectional approaches are needed to face this issue.

  17. The science teacher as the organic link in science learning: Identity, motives, and capital transfer

    Science.gov (United States)

    Alexakos, Konstantinos

    This life history study is based on in-depth interviews of five science teachers and explores themes of science teachers' experiences as science learners and how these experiences frame what I have come to call "the subjective aspects of teaching." These themes seem to imply that through such individual experiences individuals develop a personally unique lens through which they view and interpret science, science meanings, and science teaching and learning. Emerging themes created new questions to pursue and they in turn produced new themes. These were further investigated in an attempt to connect science learning and science teachers to broader issues in society. These themes include that of a dynamic, dialectical learning and understanding of science by the participants, developed and influenced through a combination of their families, their schools, and their professional experiences, and in which morals and passion play major roles. The theme of the "organic link" is also introduced and developed in this research. It includes these individuals' views of science and the scientific enterprise, their path to learning, their morals, passions, and choices, and their way of constructing knowledge and the transmission of such a process. As organic links, they are seen as a direct and necessary social connection between science and the science learner, and they foster educational experiences grounded in the social lives of their students. Not only are they seen as "transmitters" of science knowledge and the process of constructing knowledge, but they are also seen as correcting and adjusting perceived diversions of the students' thinking from that of their own. It is in this context that the concept of capital (human and cultural capital, as well as capital exchange) is also explored. These themes are seen as having immense impact on how these science teachers teach, where they teach, what is communicated to their students, and whether they become or remain science

    Mahfood, Denise Marcia

    The following dissertation reports on a qualitative exploration that serves two main goals: (1) to qualitatively define and highlight science motivation development of Black/African American and Latina/o students as they learn science in middle school, high school, and in college and (2) to reveal through personal narratives how successful entry and persistence in science by this particular group is linked to the development of their science identities. The targeted population for this study is undergraduate students of color in science fields at a college or university. The theoretical frameworks for this study are constructivist theory, motivation theory, critical theory, and identity theories. The methodological approach is narrative which includes students' science learning experiences throughout the course of their academic lives. I use The Science Motivation Questionnaire II to obtain baseline data to quantitatively assess for motivation to learn science. Data from semi-structured interviews from selected participants were collected, coded, and configured into a story, and emergent themes reveal the important role of science learning in both informal and formal settings, but especially in informal settings that contribute to better understandings of science and the development of science identities for these undergraduate students of color. The findings have implications for science teaching in schools and teacher professional development in science learning.

    2012-06-01

    US educators express concern that students are turning away from the study of science and have little interest in pursuing science careers. Nationally, science achievement scores for 8th graders are unchanged since 1996, but 12th graders' scores have significantly decreased. A shortcoming of education reform efforts is lack of attention to students' developmental needs. Science study should enable students to learn about themselves—to develop and refine their skills, define their values, explore personal interests, and understand the importance of science to themselves and others. Effective secondary science instruction requires attention to students' identity development—the key developmental task of adolescence. Secondary science teachers participated in an 8-week course focused on understanding adolescent identity development and methods for addressing identity. Transcripts of the teachers' online discussions of salient issues were analyzed to determine their perceptions regarding classroom identity work. Teachers identified several assets and obstacles to identity work that were organized into two broad categories: teacher knowledge, training opportunities, and administrative support, or lack of these; and, presence of inflexible curricula, standardized testing regimes, and increased teacher accountability. Implications for student growth and science teacher professional development are discussed.

  2. An Examination of the Processes of Student Science Identity Negotiation within an Informal Learning Community

    Science.gov (United States)

    Mark, Sheron L.

    Scientific proficiency is important, not only for a solid, interdisciplinary educational foundation, but also for entry into and mobility within today's increasingly technological and globalized workplace, as well as for informed, democratic participation in society (National Academies Press, 2007b). Within the United States, low-income, ethnic minority students are disproportionately underperforming and underrepresented in science, as well as mathematics, engineering and other technology fields (Business-Higher Education Forum, 2011; National Assessment of Educational Progress, 2009). This is due, in part, to a lack of educational structures and strategies that can support low-income, ethnic minority students to become competent in science in equitable and empowering ways. In order to investigate such structures and strategies that may be beneficial for these students, a longitudinal, qualitative study was conducted. The 15 month study was an investigation of science identity negotiation informed by the theoretical perspectives of Brown's (2004) discursive science identities and Tan and Barton's (2008) identities-in-practice amongst ten high school students in an informal science program and employed an amalgam of research designs, including ethnography (Geertz, 1973), case study (Stake, 2000) and grounded theory (Glaser & Strauss, 1967). Findings indicated that the students made use of two strategies, discursive identity development and language use in science, in order to negotiate student science identities in satisfying ways within the limits of the TESJ practice. Additionally, 3 factors were identified as being supportive of successful student science identity negotiation in the informal practice, as well. These were (i) peer dynamics, (ii) significant social interactions, and (iii) student ownership in science. The students were also uncovered to be particularly open-minded to the field of STEM. Finally, with respect to STEM career development, specific

    Researchers deal with increasingly difficult, complex issues that require more resources and tools. In addition to strictly technical problems, they are also required to produce research that is understood, at least in part, by the public and to be able to convey what are almost always difficult ideas and concepts the frontiers of knowledge. It rarely happens, but sometimes it is possible to solve several problems at the same time. As we will see throughout the article, Volunteer Computing, when properly handled, is able to supply computing power the scientific community and also serve as a window to science in the homes of citizens.

    Experiencing social identity threat from scientific findings can lead people to cognitively devalue the respective findings. Three studies examined whether potentially threatening scientific findings motivate group members to take action against the respective findings by publicly discrediting them on the Web. Results show that strongly (vs. weakly) identified group members (i.e., people who identified as "gamers") were particularly likely to discredit social identity threatening findings publicly (i.e., studies that found an effect of playing violent video games on aggression). A content analytical evaluation of online comments revealed that social identification specifically predicted critiques of the methodology employed in potentially threatening, but not in non-threatening research (Study 2). Furthermore, when participants were collectively (vs. self-) affirmed, identification did no longer predict discrediting posting behavior (Study 3). These findings contribute to the understanding of the formation of online collective action and add to the burgeoning literature on the question why certain scientific findings sometimes face a broad public opposition.

    Full Text Available Genre production uses the shared nature of cultural communication in order to establish certain kinds and models of cultural identity, and these identities go on to have a social and cultural existence outside genre communication. Anthropology insists on the shared nature of cultural communication, more precisely, on the fact that those who shape the information transmitted in this way have to share its code with the intended recipients. The anthropological study of genres is actually the study of certain cultural artefacts characteristic of the societies and cultures in which they have been created. on the fact that those who shape the information transmitted in this way have to share its code with the intended recipients.

  9. A framework for sustainability science: a renovated IPAT identity.

    Waggoner, P E; Ausubel, J H

    2002-06-11

    Learning actors' leverage for change along the journey to sustainability requires quantifying the component forces of environmental impact and integrating them. Population, income, consumers' behavior, and producers' efficiency jointly force impact. Here, we renovate the "IPAT Identity" to identify actors with the forces. Forcing impact I are P for population, A for income as gross domestic product (GDP) per capita, C for intensity of use as a good per GDP, and T for efficiency ratios as impact per good. In the "ImPACT Identity," parents modify P, workers modify A, consumers modify C, and producers modify T. Because annual percentage changes in component forces add to a change in national impact, actors' leverage is reflected transparently in consistent units of annual percentage changes that can be compared from force to force. Examples from energy and food, farming and manufacturing, and steel and water show that declining C, called dematerialization, can temper the sustainability challenge of growth (P x A), and that innovation or efficient technology that lowers T can counter rising consumption (P x A x C). Income elasticity can accommodate connections between income and other forces. From rates of change of forces, the identity can forecast impacts. Alternatively, by identifying the necessary change in forces to cause a projected impact, ImPACT can assay the likelihood and practicability of environmental targets and timetables. An annual 2-3% progress in consumption and technology over many decades and sectors provides a benchmark for sustainability.

  10. Racial identity development & perceptions of scientists of Black college students in science and non-science majors

    Gomillion, Crystall Sharee

    The focus of this research was to evaluate if differences exist in the racial identity profiles and perceptions of scientists held by 48 Black college students majoring in science (n = 17) and non-science (n = 31) fields. The study was conducted at a large, predominantly White university located in the south. All participants completed the Cross Racial Identity Scale (CRIS) and Draw-a-Scientist Test (DAST); measures used to assess six subscales of individuals' racial identity development (RID) and 16 stereotypical conceptions of scientists respectively. Fourteen volunteers also completed one-on-one interviews with the researcher to discuss information that would elucidate their responses to survey instruments. Findings from the CRIS revealed that significant differences did not exist in the science majors' and non-science majors' racial identity profiles. Both groups expressed strongest agreement with views reflected in Internalization Multiculturalist Inclusive (IMCI) and Pre-Encounter Miseducation (PM) subscales. Conversely, the science majors and non-science majors exhibited least agreement with attitudes depicted in Immersion-Emersion Anti-White (IEAW) and Pre-Encounter Self-Hatred (PSH) subscales. Results from the DAST demonstrated that both groups illustrated similar perceptions of scientists as observed by an average of four of the 16 stereotypes expressed in their images.

  13. A timeline of stable isotopes and mass spectrometry in the life sciences.

    Science.gov (United States)

    Lehmann, Wolf D

    2017-01-01

    This review retraces the role of stable isotopes and mass spectrometry in the life sciences. The timeline is divided into four segments covering the years 1920-1950, 1950-1980, 1980-2000, and 2000 until today. For each period methodic progress and typical applications are discussed. Application of stable isotopes is driven by improvements of mass spectrometry, chromatography, and related fields in sensitivity, mass accuracy, structural specificity, complex sample handling ability, data output, and data evaluation. We currently experience the vision of omics-type analyses, that is, the comprehensive identification and quantification of a complete compound class within one or a few analytical runs. This development is driven by stable isotopes without competition by radioisotopes. In metabolic studies as classic field of isotopic tracer experiments, stable isotopes and radioisotopes were competing solutions, with stable isotopes as the long-term junior partner. Since the 1990s the number of metabolic studies with radioisotopes decreases, whereas stable isotope studies retain their slow but stable upward tendency. Unique fields of stable isotopes are metabolic tests in newborns, metabolic experiments in healthy controls, newborn screening for inborn errors, quantification of drugs and drug metabolites in doping control, natural isotope fractionation in geology, ecology, food authentication, or doping control, and more recently the field of quantitative omics-type analyses. There, cells or whole organisms are systematically labeled with stable isotopes to study proteomic differences or specific responses to stimuli or genetic manipulation. The duo of stable isotopes and mass spectrometry will probably continue to grow in the life sciences, since it delivers reference-quality quantitative data with molecular specificity, often combined with informative isotope effects. © 2016 Wiley Periodicals, Inc.

  14. From object to subject: hybrid identities of indigenous women in science

    Science.gov (United States)

    McKinley, Elizabeth

    2008-12-01

    The use of hybridity today suggests a less coherent, unified and directed process than that found in the Enlightenment science's cultural imperialism, but regardless of this neither concept exists outside power and inequality. Hence, hybridity raises the question of the terms of the mixture and the conditions of mixing. Cultural hybridity produced by colonisation, under the watchful eye of science at the time, and the subsequent life in a modern world since does not obscure the power that was embedded in the moment of colonisation. Indigenous identities are constructed within and by cultural power. While we all live in a global society whose consequences no one can escape, we remain unequal participants and globalisation remains an uneven process. This article argues that power has become a constitutive element in our own hybrid identities in indigenous people's attempts to participate in science and science education. Using the indigenous peoples of Aotearoa New Zealand (called Māori) as a site of identity construction, I argue that the move from being the object of science to the subject of science, through science education in schools, brings with it traces of an earlier meaning of `hybridity' that constantly erupts into the lives of Māori women scientists.

  15. Professional development in person: identity and the construction of teaching within a high school science department

    Deneroff, Victoria

    2016-06-01

    This is a narrative inquiry into the role of professional development in the construction of teaching practice by an exemplary urban high school science teacher. I collected data during 3 years of ethnographic participant observation in Marie Gonzalez's classroom. Marie told stories about her experiences in ten years of professional development focused on inquiry science teaching. I use a social practice theory lens to analyze my own stories as well as Marie's. I make the case that science teaching is best understood as mediated by socially-constructed identities rather than as the end-product of knowledge and beliefs. The cognitive paradigm for understanding teachers' professional learning fails to consistently produce transformations of teaching practice. In order to design professional development with science teachers that is generative of new knowledge, and is self-sustaining, we must understand how to build knowledge of how to problematize identities and consciously use social practice theory.

  16. Stable isotope ratio mass spectrometry in forensic science and food adulteration research

    International Nuclear Information System (INIS)

    Kumar, B.

    2009-01-01

    Stable Isotope Ratio Mass Spectrometry (SIRMS) is an established technique for the determination of origin of geological, biological, chemical and physio-chemical samples/materials. With the development of highly precise mass spectrometers, the stable isotope ratio determination of hydrogen, carbon, nitrogen and oxygen have gained considerable interest in the fields of forensic science and food authentication. Natural variations in the isotopic composition of lighter elements occur due to fractionation effects, resulting in the finger printing of specific isotope ratio values that are characteristic of the origin, purity, and manufacturing processes of the products and their constituents. Forensic science uses scientific and technical methods to investigate traceable evidence of criminal acts. Stable isotope ratio mass spectrometry has been applied to numerous aspects of the forensic science. The analysis of explosives such as ammonium nitrate, gun powder and tri-nitro-toluene (TNT), cases of murder, armed robbery, drug smuggling, terrorism, arson and hit and run traffic accidents are a few of them. The main types of geological evidences in such cases are mud, soil, rocks, sand, gravel, dust particles, biological materials, organic particles and anthropogenic components. Stable isotopes are used as tools to corroborate and confirm the evidential leads in the investigation of such crimes. The variation in natural abundances of carbon and nitrogen and their isotopic ratios δ 13 C and δ 15 N can identify links between items found at crime scene with those of suspect. The paper discusses the applications of SIRMS in the field of forensic science and food adulteration research

  17. Integrating Service-Learning Pedagogy for Preservice Elementary Teachers' Science Identity Development

    Science.gov (United States)

    Wilson, Rachel E.; Bradbury, Leslie U.; McGlasson, Martha A.

    2015-04-01

    The purpose of this article is to explore how preservice elementary teachers (PSETs) interpreted their service-learning experiences within a pre-methods environmentally focused course and how their interpretations shaped their science teaching identities. Along a continuum of service-learning experiences were events that emphasized science learning, that focused on science teaching, and that were transitional, with elements of both science learning and science teaching. These various service-learning experiences were designed to be "boundary experiences" for professional identity development (Geijsel & Meijers in Educational Studies, 3(4), 419-430, 2005), providing opportunities for PSETs to reflect on meanings in cultural contexts and how they are related to their own personal meanings. We analyzed written reflections and end-of-course oral reflection interviews from 42 PSETs on their various service-learning experiences. PSETs discussed themes related to the meanings they made of the service-learning experiences: (a) experiencing science in relation to their lives as humans and future teachers, (b) interacting with elementary students and other PSETs, and (c) making an impact in the physical environment and in the community. The connections that PSETs were making between the discursive spaces (service-learning contexts) and their own meaning-making of these experiences (as connected to their own interests in relation to their future professions and daily lives) shows evidence of the potential that various types of science service-learning experiences have for PSETs in developing inbound science teaching identity trajectories (Wenger in Communities of practice: Learning, meaning, and identity. Cambridge: Cambridge University Press, 1998). The findings of this study point to positive outcomes for PSETs when they participate in structured service-learning experiences along a learning to teaching continuum (246).

    2014-10-01

    In this study, we conducted in-depth interviews with 52 college graduates as they entered a Postbaccalaureate Research Education Program (PREP). Our goal was to investigate what it means for these aspiring scientists, most of whom are from groups underrepresented in the sciences, to feel ready to apply to a doctoral program in the biomedical sciences. For our analysis, we developed and used a theoretical framework which integrates concepts from identity-in-practice literature with Bourdieu's formulation of cultural capital and also examined the impact of racial, ethnic, and gender identities on education and career trajectories. Five patterns of identity work for expected engagement with PREP grew out of our analysis: Credential Seekers, PI Aspirants, Path Builders, Discipline Changers, and Interest Testers. These patterns illuminate differences in perceptions of doing, being , and becoming within science; external and internal foci of identity work; and expectations for institutional and embodied cultural capital. Our findings show that preparing for graduate education is more complex than acquiring a set of credentials as it is infused with identity work which facilitates readiness beyond preparation . This deeper understanding of individual agency and perceptions allows us to shift the focus away from a deficit model where institutions and programs attempt to "fix" students, and to offer implications for programs designed to support college graduates aspiring to become scientists.

    The integration of engineering concepts and practices into elementary science education has become an emerging concern for science educators and practitioners, alike. Moreover, how children, specifically preadolescents (grades 1-5), engage in engineering design-based learning activities may help science educators and researchers learn more about children's earliest identification with engineering. The purpose of this study was to examine the extent to which engineering identity differed among preadolescents across gender and grade, when exposing students to engineering design-based science learning activities. Five hundred fifty preadolescent participants completed the Engineering Identity Development Scale (EIDS), a recently developed measure with validity evidence that characterizes children's conceptions of engineering and potential career aspirations. Data analyses of variance among four factors (i.e., gender, grade, and group) indicated that elementary school students who engaged in the engineering design-based science learning activities demonstrated greater improvements on the EIDS subscales compared to those in the comparison group. Specifically, students in the lower grade levels showed substantial increases, while students in the higher grade levels showed decreases. Girls, regardless of grade level and participation in the engineering learning activities, showed higher scores in the academic subscale compared to boys. These findings suggest that the integration of engineering practices in the science classroom as early as grade one shows potential in fostering and sustaining student interest, participation, and self-concept in engineering and science.

  4. Mapping classroom experiences through the eyes of enlace students: The development of science literate identities

    Oemig, Paulo Andreas

    The culture of a science classroom favors a particular speech community, thus membership requires students becoming bilingual and bicultural at the same time. The complexity of learning science rests in that it not only possesses a unique lexicon and discourse, but it ultimately entails a way of knowing. My dissertation examined the academic engagement and perceptions of a group (N=30) of high school students regarding their science literate practices. These students were participating in an Engaging Latino Communities for Education (ENLACE) program whose purpose is to increase Latino high school graduation rates and assist them with college entrance requirements. At the time of the study, 19 students were enrolled in different science classes to fulfill the science requirements for graduation. The primary research question: What kind of science classroom learning environment supports science literate identities for Latino/a students? was addressed through a convergent parallel mixed research design (Creswell & Plano Clark, 2011). Over the course of an academic semester I interviewed all 30 students arranged in focus groups and observed in their science classes. ENLACE students expressed interest in science when it was taught through hands-on activities or experiments. Students also stressed the importance of having teachers who made an effort to get to know them as persons and not just as students. Students felt more engaged in science when they perceived their teachers respected them for their experiences and knowledge. Findings strongly suggest students will be more interested in science when they have opportunities to learn through contextualized practices. Science literate identities can be promoted when inquiry serves as a vehicle for students to engage in the language of the discipline in all its modalities. Inquiry-based activities, when carefully planned and implemented, can provide meaningful spaces for students to construct knowledge, evaluate claims

    Black males, as one non-dominant population, remain underrepresented and less successful in science, technology, engineering, and mathematics (STEM). Researchers focused on non-dominant populations are advised against generalizations and to examine cultural intersections (i.e. race, ethnicity, gender, and more) and also to explore cases of success, in addition to cases of under-achievement and underrepresentation. This study has focused on one African American male, Randy, who expressed high-achieving STEM career goals in computer science and engineering. Furthermore, recognizing that culture and identity development underlie STEM engagement and persistence, this long-term case study focused on how Randy developed a STEM identity during the course of the study and the implications of that process for his STEM career exploration. Étienne Wenger's (1999) communities-of-practice (CoP) was employed as a theoretical framework and, in doing so, (1) the informal STEM program in which Randy participated was characterized as a STEM-for-social-justice CoP and (2) Randy participated in ways that consistently utilized an "economics" lens from beyond the boundaries of the CoP. In doing so, Randy functioned as a broker within the CoP and developed a non-traditional STEM identity-in-practice which integrated STEM, "economics", and community engagement. Randy's STEM identity-in-practice is discussed in terms of the contextual factors that support scientific identity development (Hazari et al. in J Res Sci Teach 47:978-1003, 2010), the importance of recognizing and supporting the development of holistic and non-traditional STEM identities, especially for diverse populations in STEM, and the implications of this new understanding of Randy's STEM identity for his long-term STEM career exploration.

  7. A Case Study Exploring the Identity of an In-Service Elementary Science Teacher: a Language Teacher First

    2018-01-01

    Teachers are central to providing high-quality science learning experiences called for in recent reform efforts, as their understanding of science impacts both what they teach and how they teach it. Yet, most elementary teachers do not enter the profession with a particular interest in science or expertise in science teaching. Research also indicates elementary schools present unique barriers that may inhibit science teaching. This case study utilizes the framework of identity to explore how one elementary classroom teacher's understandings of herself as a science specialist were shaped by the bilingual elementary school context as she planned for and provided reform-based science instruction. Utilizing Gee's (2000) sociocultural framework, identity was defined as consisting of four interrelated dimensions that served as analytic frames for examining how this teacher understood her new role through social positioning within her school. Findings describe the ways in which this teacher's identity as a science teacher was influenced by the school context. The case study reveals two important implications for teacher identity. First, collaboration for science teaching is essential for elementary teachers to change their practice. It can be challenging for teachers to form an identity as a science teacher in isolation. In addition, elementary teachers new to science teaching negotiate their emerging science practice with their prior experiences and the school context. For example, in the context of a bilingual school, this teacher adapted the reform-based science curriculum to better meet the unique linguistic needs of her students.

  8. Identity's identities

    DEFF Research Database (Denmark)

    Jensen, Kim Ebensgaard

    The word identity is interesting for a number of reasons. Firstly, it covers a number of specialized functions stemming from decades of research into both identity as a theoretical concept itself and into various identities and types of identity. Secondly, it also figures in non......-specialized language in which it also serves a number of functions – some of which are quite fundamental to society as such. In other words, the lexeme identity is a polysemic word and has multiple, well, identities. Given that it appears to have a number of functions in a variety of registers, including terminologies...... in Academic English and more everyday-based English, identity as a lexeme is definitely worth having a look at. This paper presents a lexicological study of identity in which some of its senses are identified and their behaviors in actual discourse are observed. Drawing on data from the 2011 section...

  9. Science teacher identity and eco-transformation of science education: comparing Western modernism with Confucianism and reflexive Bildung

    Sjöström, Jesper

    2018-03-01

    This forum article contributes to the understanding of how science teachers' identity is related to their worldviews, cultural values and educational philosophies, and to eco-transformation of science education. Special focus is put on `reform-minded' science teachers. The starting point is the paper Science education reform in Confucian learning cultures: teachers' perspectives on policy and practice in Taiwan by Ying-Syuan Huang and Anila Asghar. It highlights several factors that can explain the difficulties of implementing "new pedagogy" in science education. One important factor is Confucian values and traditions, which seem to both hinder and support the science teachers' implementation of inquiry-based and learner-centered approaches. In this article Confucianism is compared with other learning cultures and also discussed in relation to different worldviews and educational philosophies in science education. Just like for the central/north European educational tradition called Bildung, there are various interpretations of Confucianism. However, both have subcultures (e.g. reflexive Bildung and Neo-Confucianism) with similarities that are highlighted in this article. If an "old pedagogy" in science education is related to essentialism, rationalist-objectivist focus, and a hierarchical configuration, the so called "new pedagogy" is often related to progressivism, modernism, utilitarianism, and a professional configuration. Reflexive Bildung problematizes the values associated with such a "new pedagogy" and can be described with labels such as post-positivism, reconstructionism and problematizing/critical configurations. Different educational approaches in science education, and corresponding eco-identities, are commented on in relation to transformation of educational practice.

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

    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

    Expeditionary science differs from laboratory science in that expeditionary science teams conduct investigations in conditions that are often physically and socially, as well as intellectually, challenging. Team members live in close quarters for extended periods of time, team building and leadership affect the scientific process, and research tools are limited to what is available on site. Girls on Ice is an expeditionary science experience primarily for disadvantaged girls; it fully immerses girls in a mini scientific expedition to study alpine, glacierized environments. In addition to mentoring the girls through conducting their own scientific research, we encourage awareness and discussion of different sociocultural perspectives on the relation between the natural world, science, and society. The experience aligns closely with the apprenticeship model of learning, which can be effective in enhancing identification with science. Using a mixed-methods approach, we show that the Girls on Ice model helps girls (1) increase their interest and engagement in science and build a stronger science identity, (2) develop confidence, importantly they develop a combined physical and intellectual confidence; (3) engage in authentic scientific thinking, including critical thinking and problem solving; and (4) enhance leadership self-confidence. We discuss these results in a learning sciences framework, which posits that learning is inseparable from the social and physical contexts in which it takes place.

  12. Scientist Spotlight Homework Assignments Shift Students’ Stereotypes of Scientists and Enhance Science Identity in a Diverse Introductory Science Class

    2016-01-01

    Research into science identity, stereotype threat, and possible selves suggests a lack of diverse representations of scientists could impede traditionally underserved students from persisting and succeeding in science. We evaluated a series of metacognitive homework assignments (“Scientist Spotlights”) that featured counterstereotypical examples of scientists in an introductory biology class at a diverse community college. Scientist Spotlights additionally served as tools for content coverage, as scientists were selected to match topics covered each week. We analyzed beginning- and end-of-course essays completed by students during each of five courses with Scientist Spotlights and two courses with equivalent homework assignments that lacked connections to the stories of diverse scientists. Students completing Scientist Spotlights shifted toward counterstereotypical descriptions of scientists and conveyed an enhanced ability to personally relate to scientists following the intervention. Longitudinal data suggested these shifts were maintained 6 months after the completion of the course. Analyses further uncovered correlations between these shifts, interest in science, and course grades. As Scientist Spotlights require very little class time and complement existing curricula, they represent a promising tool for enhancing science identity, shifting stereotypes, and connecting content to issues of equity and diversity in a broad range of STEM classrooms.

  13. Revisiting the silence of Asian immigrant students: The negotiation of Korean immigrant students' identities in science classrooms

    Ryu, Minjung

    This dissertation is a study about Korean immigrant students' identities, including academic identities related to science learning and identities along various social dimensions. I explore how Korean immigrant students participate in science classrooms and how they enact and negotiate their identities in their classroom discursive participation. My dissertation is motivated by the increasing attention in educational research to the intersectionality between science learning and various dimensions of identities (e.g., gender, race, ethnicity, social networks) and a dearth of such research addressing Asian immigrant students. Asian immigrant students are stereotyped as quiet and successful learners, particularly in science and mathematics classes, and their success is often explained by cultural differences. I confront this static and oversimplified notion of cultural differences and Asians' academic success and examine the intersectionality between science learning and identities of Asian immigrant students, with the specific case of Korean immigrants. Drawing upon cultural historical and sociolinguistic perspectives of identity, I propose a theoretical framework that underscores multiple levels of contexts (macro level, meso level, personal, and micro level contexts) in understanding and analyzing students' identities. Based on a year-long ethnographic study in two high school Advanced Placement Biology classes in a public high school, I present the meso level contexts of the focal school and biology classes, and in-depth analyses of three focal students. The findings illustrate: (1) how meso level contexts play a critical role in these students' identities and science classroom participation, (2) how the meso level contexts are reinterpreted and have different meanings to different students depending on their personal contexts, and (3) how students negotiated their positions to achieve certain identity goals. I discuss the implications of the findings for the

  15. Emerging identities: A proposed model for an interactive science curriculum for First Nations students

    Science.gov (United States)

    Sable, Trudy

    Mi'kmaw students face a complexity of personal, cultural, and social conditions within contemporary educational systems that affect their continued participation in the educational process offered within Atlantic Canada. Despite a variety of approaches developed by educators to address the high drop out rate and lack of interest in science, the statistics remain largely unchanged. Aboriginal educators are calling for a "new story" in education that better meets the needs of Aboriginal students. This study attempts to identify the conditions and contexts necessary to bridge the gap that currently exists for Aboriginal students in science studies. The research investigates the basic relationship between learning in general and the meaning-making processes engaged in by students of a Grade 7/8 class within a Mi'kmaw reserve school. It leads to a proposal for an alternative pedagogy, or a new narrative, for teaching science to Aboriginal students and the foundations for a culturally interactive science curriculum. For educators to understand the complexity of issues affecting Mi'kmaw student achievement in science requires a theoretical framework that allows the students' lived experience to emerge. Toward this end, the research includes both phenomenological and ethnographic approaches to understanding the lived experiences and cultural narratives based on interviews with the students, a field trip within the community, and a trial chemistry lesson. I examined how these students perceive themselves in different contexts and how their sense of identity establishes the meaningfulness of particular educational content. I also assessed how person, community/cultural and social contexts affect the students' learning. Part of creating this new narrative requires recognizing knowledge, including science, as a cultural product Taking this cultural view of scientific knowledge allows us to view learning as a process of identity formation and culture as a system of symbols

  16. Professional identity in clinician-scientists: brokers between care and science.

    2017-06-01

    Despite increasing numbers of publications, science often fails to significantly improve patient care. Clinician-scientists, professionals who combine care and research activities, play an important role in helping to solve this problem. However, despite the ascribed advantages of connecting scientific knowledge and inquiry with health care, clinician-scientists are scarce, especially amongst non-physicians. The education of clinician-scientists can be complex because they must form professional identities at the intersection of care and research. The successful education of clinician-scientists requires insight into how these professionals view their professional identity and how they combine distinct practices. This study sought to investigate how recently trained nurse- and physiotherapist-scientists perceive their professional identities and experience the crossing of boundaries between care and research. Semi-structured interviews were conducted with 14 nurse- and physiotherapist-scientists at 1 year after they had completed MSc research training. Interviews were thematically analysed using insights from the theoretical frameworks of dialogical self theory and boundary crossing. After research training, the initial professional identity, of clinician, remained important for novice clinician-scientists, whereas the scientist identity was experienced as additional and complementary. A meta-identity as broker, referred to as a 'bridge builder', seemed to mediate competing demands or tensions between the two positions. Obtaining and maintaining a dual work position were experienced as logistically demanding; nevertheless, it was considered beneficial for crossing the boundaries between care and research because it led to reflection on the health profession, knowledge integration, inquiry and innovation in care, improved data collection, and research with a focus on clinical applicability. Novice clinician-scientists experience dual professional identities as care

  17. Teacher Transformation: An Exploration of Science Teachers' Changing Professional Identities, Knowledge, and Classroom Practices

    Science.gov (United States)

    Whitacre, Michelle Phillips

    This qualitative, multiple case study examines five teachers' experiences with a National Science Foundation-funded professional development (PD) program focused on science literacy. Using a three dimensional conceptual framework combining transformative learning theory, communities of practice, and sociocultural conceptions of identity it explores: the ways the "Science Literacy through Science Journalism" (SciJourn) project built professional community and influenced teacher learning; the influence of the project on participating science teachers' professional identities, knowledge, and classroom practices; and the ways teachers were or were not transformed by participation in the project. To this end, data from surveys and phenomenological interviews were analyzed through qualitative textual analysis and narrative analysis. Four of the teachers experienced a change in their stories to live by, aka, an identity shift. Three predominant themes emerged across these cases. These included a changed conceptualization of science literacy, the importance of student engagement and authenticity, and the value of SciJourn's professional development and community. The changed conceptualization of science literacy was particularly salient as it challenged these teachers' assumptions, led them to rethink how they teach science literacy, and also influenced them to re-evaluate their teaching priorities beyond the PD. Consequently, this study concludes that PD efforts should focus as much, or more, on influencing teachers' ideas regarding what and how they teach and less on teaching strategies. A close comparison between two teachers' diverging experiences with the program showed that student engagement played a significant role in teachers' perceptions of the value of project, suggesting that whether or not teachers sustain a new practice is closely tied to their students' feedback. Additionally, this analysis showed that a teacher's individualized needs and sense of efficacy

    Sociology and philosophy of science have an uneasy relationship, while the marriage of history and philosophy of science has--on the surface at least--been more successful I will take a sociological look at the history of the relationships between philosophy and history as well as philosophy and sociology of science. Interdisciplinary relations between these disciplines will be analysed through social identity complexity theory in oider to draw out some conclusions on how the disciplines interact and how they might develop. I will use the relationships between the disciplines as a pointer for a more general social theory of interdisciplinarity which will then be used to sound a caution on how interdisciplinary relations between the three disciplines might be managed.

    2013-06-01

    The demanding first years of teaching are a time when many teachers leave the teaching profession or discard the reform-minded practice emphasized in teacher preparation. If we are to lessen teacher attrition and more effectively support teachers during their development, a better understanding of what occurs during their induction into the profession is needed. The question that drove this research was what factors influence how a beginning science teacher negotiates entry into teaching? Specifically, we sought to understand how a beginning science teacher's identities interact with the teaching context; how this interaction shapes his use of reform-minded teaching practice; and how the negotiation of identity, context, and practice influence a novice teacher's employment decisions. The study involved 2 years of data collection; data included classroom and school observations, questionnaires, interviews, and teaching artifacts (such as lesson plans and assessments). The results demonstrate how conflicts in identities, institutional expectations, and personal dispositions of this novice influenced his transition in becoming a member of his school community. Implications of these interactions for teacher preparation and support are provided.

  1. Cultural politics: Linguistic identity and its role as gatekeeper in the science classroom

    Science.gov (United States)

    Hilton-Brown, Bryan Anthony

    This dissertation investigated how participation in the cultural practices of science classrooms creates intrapersonal conflict for ethnic minority students. Grounded in research perspectives of cultural anthropology, sociocultural studies of science education, and critical pedagogy, this study examined the cultural tensions encountered by minority students as they assimilate into the culture of the science classroom. Classroom interaction was viewed from the perspective of instructional congruence---the active incorporation of students' culture into science pedagogy. Ogbu's notion of "oppositional identity", Fordham's "fictive kinship", Bahktin's "antidialogics", and Freire's "critical consciousness" were brought together to examine how members of marginalized cultures develop non-normative behaviors as a means of cultural resistance. Choice of genre for public discourse was seen as a political act, representing students' own cultural affiliations. Conducted in a diverse Southern Californian high school with an annual population of over 3,900 students, this study merged ethnographic research, action research, and sociolinguistic discourse analysis. Post hoc analysis of videotaped classroom activities, focus group interviews, and samples of student work revealed students' discursive behavior to shift as a product of the context of their discursive exchanges. In whole class discussions students explained their understanding of complex phenomena to classmates, while in small group discussions they favored brief exchanges of group data. Four domains of discursive identities were identified: Opposition Status, Maintenance Status, Incorporation Status, and Proficiency Status. Students demonstrating Opposition Status avoided use of science discourse. Those students who demonstrated Maintenance Status were committed to maintaining their own discursive behavior. Incorporation Status students were characterized by an active attempt to incorporate science discourse into

    Zembylas, Michalinos; Avraamidou, Lucy

    2008-12-01

    The four essays reviewed here constitute a worthwhile attempt to discuss various aspects of postcolonial theory, and offer constructive ideas to ongoing academic as well as public conversations with respect to whether science education can meet the challenges of educating an increasingly diverse population in the 21st century. These essays are grounded in the assumption that it is difficult to make meaningful and transformative changes in science education so that educators' efforts take into consideration the dramatic changes (i.e., diverse culture and racial origins, language, economic status etc.) of `an era of globalization' in order to meet the demands of today's schools. Each of these four essays problematizes various aspects of the social and cultural conditions of science education nowadays using different `postcolonial' ideas to interpret the implications for science learning and teaching. Although the term `postcolonial' has certainly multiple meanings in the literature, we use this term here to describe the philosophical position of these essays to challenge long-standing and hegemonic practices and taken-for-granted assumptions in science education. Through critical analysis of these essays, we engage in a dialogue with the authors, focusing on two of what seem crucial issues in understanding the potential contributions as well as the risks of postcolonial concepts in science education; these issues are space and identity. We choose these issues because they permeate all four essays in interesting and often provocative ways.

    Kane, Justine M.

    This is a qualitative study of identities constructed and enacted by four 3rd-grade African American children (two girls and two boys) in an urban classroom that engaged in a year-long, integrated science-literacy project. Juxtaposing narrative and discursive identity lenses, coupled with race and gender perspectives, I examined the ways in which the four children saw and performed themselves as students and as science students in their classroom. Interview data were used for the narrative analysis and classroom Discourse and artifacts were used for the discursive analysis. A constructivist grounded theory framework was adopted for both analyses. The findings highlight the diversity and richness of perspectives and forms of engagement these young children shared and enacted, and help us see African American children as knowers, doers, and talkers of science individually and collectively. In their stories about themselves, all the children identified themselves as smart but they associated with smartness different characteristics and practices depending on their strengths and preferences. Drawing on the children's social, cultural, and ethnolinguistic resources, the dialogic and multimodal learning spaces facilitated by their teacher allowed the children to explore, negotiate, question, and learn science ideas. The children in this study brought their understandings and ways of being into the "lived-in" spaces co-created with classmates and teacher and influenced how these spaces were created. At the same time, each child's ways of being and understandings were shaped by the words, actions, behaviors, and feelings of peers and teacher. Moreover, as these four children engaged with science-literacy activities, they came to see themselves as competent, creative, active participants in science learning. Although their stories of "studenting" seemed dominated by following rules and being well-behaved, their stories of "sciencing" were filled with exploration, ingenuity

    2017-12-01

    This study examines the transformation and dynamic nature of one teacher candidate's (Susan) identity as a learner and teacher of science throughout an innovative science methods course. The goal of this paper is to use theoretically derived themes grounded in cultural-historical activity theory (CHAT) and situated learning theory to determine the ways in which Susan's identity as a learner and teacher of science was influenced by her experiences in the course, and to describe how she made meaning of her transformative process. The following are the three theoretical themes: (1) learning contributes to identity development, (2) identity development is a dialogical process that occurs between individuals, not within individuals, and (3) social practice leads to transformations and transformations lead to the creation of new social practices. Within each theme, specific experiences in the science methods course are identified that influenced Susan's identity development as a teacher of science. Knowing how context and experiences influence identity development can inform design decisions concerning teacher education programs, courses, and experiences for candidates.

    The Earth Science Women's Network (ESWN) is an international network of and for early-career women geoscientists, including graduate students, postdocs, faculty, program managers, and government, non-government and industry researchers. The mission of ESWN since 2002 is to promote career development, build community, provide informal mentoring and support, and facilitate professional collaborations, all towards making women successful in their scientific careers. With support from a National Science Foundation ADVANCE PAID grant, ESWN is meeting those goals through activities such as the workshop "Defining Your Research Identity." The overall goals of the 2011 ESWN Workshop were to help women at all career stages-but particularly early in their chosen track-to think through their personal, career and research goals, and to articulate these interests and goals in a way that reflects their professional strengths, both verbally and in writing. The focus of "Defining Your Research Identity" provided an opportunity for participants to walk away with a better sense of who they are, what they want, and how to achieve their goals by helping them identify the steps, resources and support needed. "Defining Your Research Identity," was selected as a workshop topic because the theme is relevant to all career stages. In particular, we set workshop goals of identifying personal strengths, defining a mission statement, networking with other ESWN members, and putting the newly-developed personal mission into action. Participants reported significant increases in personal motivation and support and encouragement from the network to pursue their goals, including research, writing, and applications for funding and programs.

    Modern technical education in British Columbia has been affected by two societal trends: in industry, engineering technology evolved as a discipline to bridge the increasing chasm between the process-oriented skill sets of tradespersons/technicians, and the declarative knowledge focus of engineering; in education, the provincial college and institute system was created to address the need for a new post-secondary credential situated between trades certificates and university degrees. The Applied Science Technologist arguably forms the intersection of these two concepts. Almost forty years after its inception, it is timely to ask if the original model has matured into a distinct occupational category in industry, education, and in the public mind. The thesis proposes three environments, the Formative, Market and Public Domain, respectively. Interviews, surveys and personal experience afforded insights into the dynamics of these domains with respect to a fledgling occupational category, while the socio-philosophical concepts of culture, habitus and social imaginary provide the tools to interpret the findings. The thesis postulates that an emerging occupational category will not only challenge existing cultures and habitus, but that over time it will influence the imaginaries of each domain and society as a whole. Ultimately, the occupational category will be truly successful only when the general public is able to distinguish it from related disciplines. Charles Taylor's writings on multiculturalism are used to discuss identity and recognition of the Applied Science Technologist in each domain while Pierre Bourdieu's perspectives on the existence of habitus and self-proliferating elites form the framework to examine the relationships between technologists and engineers. Taylor's theory of multiple concurrent social imaginaries guides the comparison of divergent expectations among academic, career and vocational instructors at British Columbia's colleges. The thesis

    This research seeks to understand the experiences of African American female undergraduates in STEM. It investigates how familial factors and science identity formation characteristics influence persistence in STEM while considering the duality of African American women's status in society. This phenomenological study was designed using critical race feminism as the theoretical framework to answer the following questions: 1) What role does family play in the experiences of African American women undergraduate STEM majors who attended two universities in the UNC system? 2) What factors impact the formation of science identity for African American women undergraduate STEM majors who attended two universities in the UNC system? Purposive sampling was used to select the participants for this study. The researcher conducted in-depth interviews with 10 African American female undergraduate STEM major from a predominantly White and a historically Black institution with the state of North Carolina public university system. Findings suggest that African American families and science identity formation influence the STEM experiences of the African American females interviewed in this study. The following five themes emerged from the findings: (1) independence, (2) support, (3) pressure to succeed, (4) adaptations, and (5) race and gender. This study contributes to the literature on African American female students in STEM higher education. The findings of this study produced knowledge regarding policies and practices that can lead to greater academic success and persistence of African American females in higher education in general, and STEM majors in particular. Colleges and universities may benefit from the findings of this study in a way that allows them to develop and sustain programs and policies that attend to the particular concerns and needs of African American women on their campuses. Finally, this research informs both current and future African American female

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

    Science.gov (United States)

    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.

  11. The Single Sex Debate for Girls in Science: a Comparison Between Two Informal Science Programs on Middle School Students' STEM Identity Formation

    Currently, there are policy debates regarding the efficacy and legality of single sex formal and informal education programs. This issue is particularly poignant in science education due to the historical marginalization of women in these fields. This marginalization has resulted in women being positioned as a stigmatized group within many science, technology, engineering, and mathematics (STEM) related fields. Research points to adolescence as the age where this sense of marginalization begins to develop. As a result, policy responses have utilized various frameworks such as: increased access for women, changing pedagogy to address women's learning styles, changing the language and culture of science to prevent marginalization of stigmatized groups, and finally exploring the role that individual identity plays in the marginalization of women. This study adds to the policy debate as it applies to single sex education by comparing middle school participants' STEM identity formation during two informal science learning environments (an all girls' STEM camp and a co-educational STEM camp). Additionally, this study focuses on the influence of camp activities within two informal science education programs: particularly the provision of role models and authentic STEM research activities, as means to improve STEM identity and make these fields relevant to the lives of middle school students. The results indicate that both camps improved girls' STEM identities. These findings suggest that the single sex environment is not as important to STEM identity as the pedagogy used within the program.

    Considerable research, policy, and programmatic efforts have been dedicated to addressing the participation of particular populations in STEM for decades. Each of these efforts claims equity-related goals; yet, they heavily frame the problem, through pervasive STEM pipeline model discourse, in terms of national needs, workforce supply, and competitiveness. This particular framing of the problem may, indeed, be counter to equity goals, especially when paired with policy that largely relies on statistical significance and broad aggregation of data over exploring the identities and experiences of the populations targeted for equitable outcomes in that policy. In this study, I used the mixed-methods approach of critical discourse and critical quantitative analyses to understand how the pipeline model ideology has become embedded within academic discourse, research, and data surrounding STEM education and work and to provide alternatives for quantitative analysis. Using critical theory as a lens, I first conducted a critical discourse analysis of contemporary STEM workforce studies with a particular eye to pipeline ideology. Next, I used that analysis to inform logistic regression analyses of the 2006 SESTAT data. This quantitative analysis compared and contrasted different ways of thinking about identity and retention. Overall, the findings of this study show that many subjective choices are made in the construction of the large-scale datasets used to inform much national science and engineering policy and that these choices greatly influence likelihood of retention outcomes.

    The United States Bureau of Labor Statistics (2010) expects new industries to generate approximately 2.7 million jobs in science and technology by the year 2018, and there is concern as to whether there will be enough trained individuals to fill these positions. A tremendous resource remains untapped, African American students, especially African American males (National Science Foundation, 2009). Historically, African American males have been omitted from the so called science pipeline. Fewer African American males pursue a science discipline due, in part; to limiting factors they experience in school and at home (Ogbu, 2004). This is a case study of African American males who are enrolled in advanced science courses at a predominantly African American (84%) urban high school. Guided by expectancy-value theory (EVT) of achievement related results (Eccles, 2009; Eccles et al., 1983), twelve African American male students in two advanced science courses were observed in their science classrooms weekly, participated in an in-depth interview, developed a presentation to share with students enrolled in a tenth grade science course, responded to an open-ended identity questionnaire, and were surveyed about their perceptions of school. Additionally, the students' teachers were interviewed, and seven of the students' parents. The interview data analyses highlighted the important role of supportive parents (key socializers) who had high expectations for their sons and who pushed them academically. The students clearly attributed their enrollment in advanced science courses to their high regard for their science teachers, which included positive relationships, hands-on learning in class, and an inviting and encouraging learning environment. Additionally, other family members and coaches played important roles in these young men's lives. Students' PowerPoint(c) presentations to younger high school students on why they should take advanced science courses highlighted these

    The concept that cellular terminal differentiation is stably maintained once development is complete has been questioned by numerous observations showing that differentiated epithelium may undergo an epithelial-to-mesenchymal transition (EMT) program. EMT and the reverse process, mesenchymal-to-epithelial transition (MET), are typical events of development, tissue repair, and tumor progression. In this study, we aimed to clarify the molecular mechanisms underlying these phenotypic conversions in hepatocytes. Hepatocyte nuclear factor 4α (HNF4α) was overexpressed in different hepatocyte cell lines and the resulting gene expression profile was determined by real-time quantitative polymerase chain reaction. HNF4α recruitment on promoters of both mesenchymal and EMT regulator genes was determined by way of electrophoretic mobility shift assay and chromatin immunoprecipitation. The effect of HNF4α depletion was assessed in silenced cells and in the context of the whole liver of HNF4 knockout animals. Our results identified key EMT regulators and mesenchymal genes as new targets of HNF4α. HNF4α, in cooperation with its target HNF1α, directly inhibits transcription of the EMT master regulatory genes Snail, Slug, and HMGA2 and of several mesenchymal markers. HNF4α-mediated repression of EMT genes induces MET in hepatomas, and its silencing triggers the mesenchymal program in differentiated hepatocytes both in cell culture and in the whole liver. The pivotal role of HNF4α in the induction and maintenance of hepatocyte differentiation should also be ascribed to its capacity to continuously repress the mesenchymal program; thus, both HNF4α activator and repressor functions are necessary for the identity of hepatocytes.

    In recent decades, changes in society have deeply affected the internal organization and the main goals of schools. These changes are particularly important in science education because science is one of the major sources of change in peoples' lives. This research provided the opportunity to investigate how these changes affect the way teachers develop their classroom activities. In this work, we focus on science as part of the cultural identity of a society and how this identity affects the process of teaching and learning inside the classroom. Other works have shown that certain social characteristics such as gender, race, religion, etc., can create a cultural barrier to learning science. This results in an obstacle between those particular students and the science that is taught, hindering their learning process. We first aim to present the notion of identity in education and in other related fields such as social psychology and sociology. Our main purpose is to focus on identity in a school setting and how that identity affects the relationship students have with the science content. Next, we present and analyze an intervention in the subject of Modern and Contemporary Physics composed by a sequence of activities in a private school in the region of Sao Paulo State, Brazil. This intervention serves to illustrate how scientific topics may be explored while considering aspects of cultural differences as an obstacle. The intervention was completed in two steps: first, in the classroom with a discussion concerning scientific works and nationality of scientists, with one being a Brazilian physicist; second, taking students to visit a particle collider at the University of São Paulo. One of the results of our research was realizing that students do not perceive science as something representative of the Brazilian cultural identity. At the same time, the activity gave the students the opportunity to make the connection between doing physical sciences at an

    2008-09-01

    In genocide, victims must represent an ethnic, racial, religious or national group. But is victim identity a question of science or law? Must victims be a socially recognized group or can group identity exist solely in the mind of the perpetrator? This question is relevant to the on-going crisis in Darfur. The "Arab-on-African" violence depicted in the media encompasses identities not shared by Darfurians. This study details an evaluation of victim identity in Darfur, based on field research and literature review. Darfurians are defined by subsistence strategy and economic groups are not protected under genocide law. Whether Darfur is genocide depends on whether victims must conform to scientific group classifications or need only be defined by their relationship to the perpetrators.

    Jackson, Phoebe A.; Seiler, Gale

    2017-11-01

    Latecomers to science are students who take non-traditional routes into postsecondary science because they are initially missing prerequisites. Latecomers have a lower rate of persistence than traditional science students. This critical discourse analysis of an online forum thread uses Gee's toolkit to explore how latecomers, who have histories of not being recognized as smart enough to do science, find new ways to identify with science. Applying a theoretical lens in which identity is viewed as a process of continual negotiation, which is constrained and afforded by the resources of the relevant figured worlds, it is shown how four latecomers shared reinterpreted histories of being recognized as not smart enough to do science and in doing so, formed solidarity. As part of this process they co-produced a new cultural model in which the ability or inability to ask questions led respectively to success (good grades) or failure (low grades) in science. Used in conjunction with their solidarity, they were not only able to successfully position themselves in the elite figured world of science, but also to reify the result in a form that could potentially support future identification with science. Aspects of the online forum that supported the co-production are explored, including its ability to help students draw on resources from outside of the science program. The importance of encouraging students to discuss their struggles with science and the accompanying construction of solidarity is also discussed. This research is of particular interest to practitioners and researchers interested in supporting non-traditional science students such as latecomers, especially those wishing to move away from deficit views of these students and towards a more complex and agentic understanding of persistence and identity in science.

    Grimes, Nicole K.

    2013-06-01

    A growing body of teacher identity-based research has begun to embrace that the development of self-understanding about being a teacher is critical to learning how to teach. Construction of a professional teacher identity requires much more beyond mere content, skills and a foundational pedagogy. It also includes an intersection of the personal and professional self, which gives way to the emergence of multiple identities in the classroom. An educator's gender, nationality, language and interests among other tenets all permeate the classroom field and coexist alongside the professional role identity. This paper aims to use narrative as a way to discuss how science educators can mediate holding several identities in the classroom in order to create an environment characterized by successful teaching and learning. Drawing from an array of sociocultural theoretical perspectives, complementary constructs of identity by Jonathan Turner (Face to face: toward a sociological theory of interpersonal behavior. Stanford University Press, Stanford, CA, 2002) and Amartya Sen (Identity and violence: the illusion of destiny. W. W. Norton, New York, 2006), George Lakoff's (Metaphors we live by. University of Chicago Press, Chicago, 1980) work on metonymy, and David Bloome's (2005) theorization of the power of caring relationships, I explore the ways in which my Black female Caribbean identity has transformed the science classroom field and created positive resonance for some of my privileged White students who have Caribbean caretakers at home. To begin, I unpack how Afro-Caribbean immigration to urban centers in the United States continues to produce childcare occupational opportunities in places like New York City. Being a first generation Trinidadian immigrant, my many identities have structured my science teaching praxis and consequently transformed the way my students learn science. A significant part of this paper is a reflexive account of experiences (primarily dialogue

    2014-04-01

    In the broadest sense, the goal for primary science teacher education could be described as preparing these teachers to teach for scientific literacy. Our starting point is that making such science teaching accessible and desirable for future primary science teachers is dependent not only on their science knowledge and self-confidence, but also on a whole range of interrelated sociocultural factors. This paper aims to explore how intersections between different Discourses about primary teaching and about science teaching are evidenced in primary school student teachers' talk about becoming teachers. The study is founded in a conceptualisation of learning as a process of social participation. The conceptual framework is crafted around two key concepts: Discourse (Gee 2005) and identity (Paechter, Women's Studies International Forum, 26(1):69-77, 2007). Empirically, the paper utilises semi-structured interviews with 11 primary student teachers enrolled in a 1-year Postgraduate Certificate of Education course. The analysis draws on five previously identified teacher Discourses: `Teaching science through inquiry', `Traditional science teacher', `Traditional primary teacher', `Teacher as classroom authority', and `Primary teacher as a role model' (Danielsson and Warwick, International Journal of Science Education, 2013). It explores how the student teachers, at an early stage in their course, are starting to intersect these Discourses to negotiate their emerging identities as primary science teachers.

  1. Navigating emotions and identity: Learning to teach science in a high needs school

    Science.gov (United States)

    Rose, Karen J.

    As student populations in the United States become more diverse, teacher education programs are challenged to find innovative and effective ways to prepare teachers for the twenty-first century. However, the goal of "science for all" continues to elude many students in urban and high needs settings where science achievement gaps persist, teacher turnover is high, and novice teachers are often hired to fill those vacancies. Researchers have examined teachers' beliefs, attitudes, practices, as well as content and pedagogical knowledge and made progressive strides in illuminating the complexities of urban classrooms and how we can better prepare teachers for these settings. However, only recently have we begun to venture into the affective areas of teaching to investigate how these areas of human nature interact to influence instruction. This research follows three preservice teachers placed in a high needs school during their student teaching semester. In this case, a high need is described as a school with more than 30% of the students who meet the poverty criteria under section 1113(a)(f) of the Elementary and Secondary Education Act of 1965. This case study explored the connections between preservice teachers' emotions, identity and the implementation of student-centered science instruction during the participants' student teaching experience. Data collection included observations, interviews, and physical artifacts. The interviews included the Teachers' Pedagogical Philosophy Interview (Richardson & Simmons, 1994) and the Meta-Emotions Interview (Gottman, Katz & Hooven, 1997) as well as general interview questions that illuminated the participants' views on teaching, their emotions, life history and identity. Multiple naturalistic observations were used to describe the interactions between the preservice teachers and the students during the implementation of student-centered lessons. Physical artifacts included weekly journals and lesson plans. These artifacts

    2014-07-01

    Full Text Available In this article we advocate the methodological feedback loop in the study of the dynamical self at the crossroads of performance philosophy, (artistic performance, and the philosophy of science. We point to the importance of the dynamics of methodology transfer between arts and sciences and the “interactive continuum” proposed by Newman & Benz in 1998. In the first part of this paper we give a comparative review of the research context relevant for our field of study, and we explain our research hubs in approaching the concept of “performance”. We suggest the possibility to define our filed of research in three equally legitimate ways: as philosophy-of-performance, philosophy-as-performance and performance-as-philosophy. In our recent work we are primarily interested in artistic performances that incorporate elements of artistic practice in the methodology of research output (Frayling 1993, as well as in the potentials of performative aspects of scientific praxis and methodology. However, the conceptual background relevant for this paper is in the field of process philosophy and its relation to science (Birkhard’s “interactivist model” 2009; Campbell’s “process-based model for an interactive ontology” 2009. We attribute particular importance to the notion of “autopoietic feedback” (Maturana and Varela 1974; Luhmann 1990. The second part addresses the issue of transcending identity in the representations of the self and the other; the relationship between Theory-Theory (TT and Simulation Theory (ST, as well as some recent attempts at combining different theories of mind (e.g. Barlassina 2013. We also deal with the notion of “embodied praxis” (Gallagher and Meltzoff 1996; we mention some neuroscientific insights into the similar phenomena, and – commenting on the importance of the dialogue between neuroscientists and philosophers (Changeux and Ricour – we give an example of an enactive approach to understanding

  3. Socially situated activities and identities: Second-grade dual language students and the social construction of science

    Science.gov (United States)

    Bryce, Nadine

    Latina and Latino American students are among the lowest achievers in science, when compared to European and Asian American students, and are highly underrepresented in science careers. Studies suggested that a part of this problem is students' lack of access to science, due to their status as English language learners and their perceived status as deficient students. This study investigated the social construction of science in a second grade dual language urban classroom that offered bilingual students access to science, while positioning them as competent, capable learners. What participants valued in science was interpreted from their stated beliefs and attitudes, as well as their patterned ways of reading, writing, and talking. A bilingual European American teacher and three Latina and Latino focal students were observed over the course of 10 weeks, as they enacted a science unit, in English, on habitats. Science lessons were videotaped, documented with field notes, and transcribed. Interviews with the teacher and students were audiotaped and transcribed, and relevant curriculum documents, and teacher- and student-generated documents, copied. Gee's (1999) d/Discourse analysis system was applied to the transcripts of science lessons and interviews as a way to understand how participants used language to construct situated activities and identities in science. Curriculum documents were analyzed to understand the positioning of the teacher and students by identifying the situated activities and roles recommended. Students' nonfiction writing and published nonfiction texts were analyzed for linguistic structures, semantic relationships and conventions of science writing. Results indicated that the teacher drew on traditional and progressive pedagogical practices that shaped her and her students' science activities and situated identities. The teacher employed traditional talk strategies to build science themes, while students enacted their roles as compliant

  4. Education biographies from the science pipeline: An analysis of Latino/a student perspectives on ethnic and gender identity in higher education

    Science.gov (United States)

    Lujan, Vanessa Beth

    This study is a qualitative narrative analysis on the importance and relevance of the ethnic and gender identities of 17 Latino/a (Hispanic) college students in the biological sciences. This research study asks the question of how one's higher education experience within the science pipeline shapes an individual's direction of study, attitudes toward science, and cultural/ethnic and gender identity development. By understanding the ideologies of these students, we are able to better comprehend the world-makings that these students bring with them to the learning process in the sciences. Informed by life history narrative analysis, this study examines Latino/as and their persisting involvement within the science pipeline in higher education and is based on qualitative observations and interviews of student perspectives on the importance of the college science experience on their ethnic identity and gender identity. The findings in this study show the multiple interrelationships from both Latino male and Latina female narratives, separate and intersecting, to reveal the complexities of the Latino/a group experience in college science. By understanding from a student perspective how the science pipeline affects one's cultural, ethnic, or gender identity, we can create a thought-provoking discussion on why and how underrepresented student populations persist in the science pipeline in higher education. The conditions created in the science pipeline and how they affect Latino/a undergraduate pathways may further be used to understand and improve the quality of the undergraduate learning experience.

  5. A case study of the effects of social experiences on the science identity formation of Mexican American females in high school chemistry

    Beeton, Renee P.

    Mexican Americans are a rapidly growing ethnic group in the United States. However, they are noticeably absent from physical science fields. Little research has explored the experiences of Mexican American girls in high school chemistry. The theories of identity based on communities of practice and multicultural feminism framed this year-long case study of nine Mexican American girls in a high school chemistry course. This study explored the social encounters and experiences that shaped the participants' identities and how their views of themselves affected their attitudes towards high school chemistry and future science careers. Data collection included a focus group and in-depth interviews with the participants, classroom observations, and teacher interviews. Five main identities influenced the participants' potential to become a scientist: ethnic, gender, science, student, and college. Mexican ethnic identity was the overarching identity; however gender also influenced the participants' other identities. The participants were aware of ethnic gender stereotypes that might hinder them from being successful in science. Also, ethnic factors, such as citizenship and abilities to receive financial aid limited their views of themselves as chemists. Participatory science, student, and school identities were all needed in order for the participants to be potential scientists. Family expectations, authentic relationships with teachers, and personal connections were important factors in the development of these participatory identities.

  6. A qualitative study of science education in nursing school: Narratives of Hispanic female nurses' sense of identity and participation in science learning

    Gensemer, Patricia S.

    The purpose of this qualitative study was to learn from Hispanic nursing students regarding their experiences as participants in science learning. The participants were four female nursing students of Hispanic origin attending a small, rural community college in a southeastern state. The overarching question of this study was "In what ways does being Hispanic mediate the science-related learning and practices of nursing students?" The following questions more specifically provided focal points for the research: (1) In what ways do students perceive being Hispanic as relevant to their science education experiences? (a) What does it mean to be Hispanic in the participants' home community? (b) What has it meant to be Hispanic in the science classroom? (2) In what ways might students' everyday knowledge (at home) relate to the knowledge or ways of knowing they practice in the nursing school community? The study took place in Alabama, which offered a rural context where Hispanic populations are rapidly increasing. A series of four interviews was conducted with each participant, followed by one focus group interview session. Results of the study were re presented in terms of portrayals of participant's narratives of identity and science learning, and then as a thematic interpretation collectively woven across the individuals' narratives. Portraitures of each participant draw upon the individual experiences of the four nursing students involved in this study in order to provide a beginning point towards exploring "community" as both personal and social aspects of science practices. Themes explored broader interpretations of communities of practice in relation to guiding questions of the study. Three themes emerged through the study, which included the following: Importance of Science to Nurses, Crossing with a Nurturing and Caring Identity, and Different Modes of Participation. Implications were discussed with regard to participation in a community of practice and

    Plant roots release compounds, such as root exudates, which can alter soil organic matter (SOM) decomposition and have large impacts on soil carbon (C) retention. The changes in SOM turnover resulting from the addition of organic and/or inorganic substrates are termed 'priming effects'. In this study we examine the effects of root exudates on the priming of cellulose added as particulate organic matter. We amended soil microcosms with 13C-cellulose in the presence or absence of artificial root exudate additions and incubated over time for 45 days. Soils receiving the root exudate (RE) were given either one large dose or multiple, small doses of RE. In each treatment we tracked operational taxonomic units (OTUs) assimilating 13C from cellulose (herein, known as a 'responder') over time using DNA stable isotope probing coupled with next generation sequencing. In all treatments the same amount of cellulose-13C was respired indicating the addition of RE did not result in the priming of cellulose decomposition. However, cellulose responders were different depending on treatment and time of sampling (days 14, 28 and 45). We identified a total of 10,361 OTUs, of which there were 369 cellulose responders in the cellulose only treatment, 273 in the repeated, small dose RE treatment, and 358 in the RE single, large dose treatment. Most of the cellulose responders found in all treatments belonged to phyla Bacteroidetes, Planctomycetes, Proteobacteria, Verrucomicrobia, and Chloroflexi. The response time of phyla varies; for instance, more OTUs in Bacteroidetes were observed on day 14 and diminish with each subsequent sampling time. On the other hand, OTUs in Verrucomicrobia increased in response over time. Our study shows no priming effect resulting from the addition of root exudates, although the identity of the microbial mediators of cellulose decomposition varies in each treatment.

    "Robotics as Science (re)Form" utilizes qualitative research methods to examine the career trajectories and gender identity formation of female youth participating as members of an all-girl, academic team within the male-dominated environment of the FIRST Robotics competition. Following the constant comparative approach (Glaser & Strauss, 1967), my project relies upon triangulating ethnographic data drawn from extensive field notes, semi-structured interviews, and digital and video imagery compiled over two years of participant observation. Drawing upon the sociolinguistic "community of practice" (CoP) framework (Eckert & McConnell-Ginet, 1992; Lave & Wenger, 1991; Wenger, 1998), this study maps the range of gendered "identities" available to girls involved in non-traditional academic and occupational pursuits within a local context, and reveals the nature, structure and impact of power operating within this CoP, a significantly underdeveloped construct within the language and gender literature. These research findings (1) contribute to refining theories of situated or problem based learning with a focus on female youth (Lave & Wenger, 1991; Wenger, 1998); (2) reveal affordances and barriers within the local program design that enable (and preclude) women and minority youth entering the engineering pipeline; and (3) enrich our understanding of intragroup language and gendered "practices" to counter largely essentializing generalizations based upon quantitative analysis.

  12. Science teacher development and the lens of social media: An investigation into the identity and influences upon the development of elementary pre-service science teachers

    Wall, Steven D.

    Pre-service teacher education is committed to the cultivation of different forms of competency that include, but are not limited to, content knowledge and pedagogical skill (Levin, Hammer, & Coffey, 2009; Yerrick, 2005). While advances in practice have been made, pre-service elementary teachers (PS-ESTs) continue to exhibit anxiety and doubt about self-efficacy in science teaching. Teacher education is designed to encourage PS-ESTs to formulate useful practices, but PS-ESTs must first overcome limitations and anxiety generated by past, personal experiences and an acknowledged discomfort with science. While this goal is accomplished through contexts designed with that intent (e.g. methods courses, field experiences), challenges remain. Twenty-first century elementary teacher education research needs to examine influences associated with individual identities within specific roles (Gee, 2000), teaching and learning contexts and their inherent influences, and interactions that are enhanced by the increasing presence and influence of social networks. To examine and better understand identity, contexts, and interactional influences, blogs from two cohorts of PS-ESTs were examined to better understand how teacher education practices influenced PS-ESTs and to determine PS-ESTs beliefs about the teacher's role. The study was designed to answer the following research questions: "What is learned about the identity of PS-ESTs authored through social media, what contextual influences are acknowledged by PS-ESTs, and what interactions are occurring and what roles are they playing in the development of PS-ESTs?" This study used grounded theory and perceptual control theory (PCT) to analyze and reduce data to make assertions about PS-ESTs' development as teachers and influences upon their practices. Findings illuminated components of PS-EST teaching identities and suggested multiple implications within different domains, including the role of PST understandings of science

    Women's representation in science has changed substantially, but unevenly, over the past 40 years. In health and biological sciences, for example, women's representation among U.S. scientists is now on par with or greater than men's, while in physical sciences and engineering they remain a clear minority. We investigated whether variation in proportions of women in scientific disciplines is related to differing levels of male-favoring explicit or implicit stereotypes held by students and scientists in each discipline. We hypothesized that science-is-male stereotypes would be weaker in disciplines where women are better represented. This prediction was tested with a sample of 176,935 college-educated participants (70% female), including thousands of engineers, physicians, and scientists. The prediction was supported for the explicit stereotype, but not for the implicit stereotype. Implicit stereotype strength did not correspond with disciplines' gender ratios, but, rather, correlated with two indicators of disciplines' scientific intensity, positively for men and negatively for women. From age 18 on, women who majored or worked in disciplines perceived as more scientific had substantially weaker science-is-male stereotypes than did men in the same disciplines, with gender differences larger than 0.8 standard deviations in the most scientifically-perceived disciplines. Further, particularly for women, differences in the strength of implicit stereotypes across scientific disciplines corresponded with the strength of scientific values held by women in the disciplines. These results are discussed in the context of dual process theory of mental operation and balanced identity theory. The findings point to the need for longitudinal study of the factors' affecting development of adults' and, especially, children's implicit gender stereotypes and scientific identity. PMID:25964765

    2008-04-01

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

  18. Kindergarten girls "illuminating" their identities-in-practice through science instruction framed in explanation building: From the shadows into the light

    Science.gov (United States)

    McDyre, Alicia M.

    Recent research on young children's learning has revealed that they are capable of sophisticated scientific reasoning and has prompted a new era of reform framed around the integration of three main strands -- core disciplinary ideas, scientific and engineering practices, and cross-cutting themes. Given the documented issues with girls in science in later grades, I chose to examine their participation in scientific norms and practices in kindergarten to gain insights into their identities-in-practice. From the perspective of identity as an enactment of self, I used the lens identities-in-practice (Lave & Wenger, 1991) to examine the impact that having classroom science instruction framed around constructing explanations with evidence would have on the girls in the class. In this study, I drew from theories of sociocultural learning, positioning, and identities-in-practice to study: a) the norms of participation, b) the authoring and positioning of girls, and c) the identities-in-practice that the girls' enacted in the kindergarten science classroom. Using a research design informed by qualitative methods and participant observation, I analyzed data using a constant comparative approach and crafted case studies of four girls in the science classroom. Three assertions were generated from this study: a) Identity-in-practice manifests differently in different literacy practices and shows how students chose to be science students across time and activities- a focus on one literacy practice alone is insufficient to understand identity; b) The ways in which the teacher positions girls, especially "quiet" girls, is essential for engaging them in productive participation in science discourse and learning; and c) A focus on classroom science instruction grounded in constructing explanations from evidence provided a consistent framework for students' writing and talking, which facilitated the establishment of expectations and norms of participation for all students

  19. Narratives of location: School science identities and scientific discourse among Navajo women at the University of New Mexico

    Science.gov (United States)

    Brandt, Carol B.

    This research examines the interplay of scientific discourse and students' sense of self among four Navajo (Dine) women as they major in science at a university in the southwestern United States. This dissertation research is an ethnographic case study of Navajo women as they were completing their final year of undergraduate study in the life sciences at a university. How do Navajo women express their identity in Western science at the university? What role does scientific discourse play in this process? This research employs a feminist poststructural approach to language and expands the way discourse has typically been addressed in science education. I expand the notion of discourse through poststructuralism by recognizing the co-constitutive role of language in fashioning realities and generating meaning. Data sources in this study included transcripts from one-on-one interviews, electronic correspondence (e-mail), observations of social contexts on campus, students' writing for science courses, university policy statements, departmental outcomes assessments, web profiles of student research in science, and a researcher's reflective journal. This study took place beginning in January 2002 and continued through May of 2003 at the University of New Mexico. After completing the thematic (constant comparative analysis) and an analysis of metaphors, I "retold" or "restoried" the narratives collected during interviews. In the cross case analysis, I compared each participant's description of those discursive spaces that afforded engagement with science, and those locations where their awareness of academic language was heightened in a process of metadiscourse. I identified these spaces as locations of possibility in which students and their mentors (or instructors) valued connected knowing, acknowledged each other's history, culture, and knowledge, and began speaking to each other subject-to-subject to challenge normative views of schooling. The participants in this

    Deviant burials can reveal important information about both social and individual identity, particularly when the mortuary record is supplemented by an examination of skeletal remains. At the postmedieval (17th to 18th c. AD) cemetery of Drawsko (Site 1), Poland, six individuals (of n = 285) received deviant, anti-vampiristic mortuary treatment. A previous study using radiogenic strontium isotope ratios ( x¯= 0.7112 ± 0.0006, 1σ, n = 60) found that these "vampires" were in fact locals, not migrants to the region targeted for deviant burial due to their status as immigrant outsiders. However, considerable geologic overlap in strontium isotope ratios across the North European Plain may have masked the identification of at least some nonlocal individuals. This study further contextualizes strontium isotope ratios using additional biogeochemical data to test the hypothesis that additional nonlocals were present in the Drawsko cemetery. Stable oxygen and carbon isotopes from the dental enamel of 58 individuals interred in both normative and atypical burials at Drawsko were analyzed. Both δ 18 O c(VPDB) ( x¯= -4.5 ± 0.7‰) and δ 13 C ap isotope values ( x¯= -13.6 ± 0.8‰) displayed little variability and were not significantly different between vampire and normative burials, supporting prior strontium results of a largely local population. Nevertheless, homogeneity in oxygen isotope values across other northern European sites makes it difficult to speculate about isotopic regional diversity, leaving open the possibility that additional migrants to the region remain undetected. Additionally, carbon isotope values point to a locally sourced diet dominated by C 3 resources but with some supplementation by C 4 goods that likely included millet, fitting with historic descriptions of postmedieval diet in Poland. Those interred as vampires appear local to the region and thus likely underwent deviant funerary treatment due to some other social

    Universities and research centers that use stable isotopes follow a worldwide trend in owning laboratories isotope ratio that serves multiple users, as well as minimize maintenance costs, operation and staff training. For this purpose it was created in 1998, the Center Stable Isotopes 'Centro de Isotopos Estaveis' - CIE, which is an auxiliary unit linked to the Institute of Biosciences (IB) of the Sao Paulo State University - UNESP Botucatu Campus, Brazil. The best way to CIE grow and achieve excellence are already disclose the methodologies employed and practice areas consolidated to find new partnerships with different applications, and also seek new methods of analysis that can expand areas. The aim of this study is to disseminate methodologies for analysis of isotope ratio and areas of the CIE. The CIE analyzes the isotopic ratios 13 C/ 12 C, 15 N/ 14 N, 2 H/ 1 H and 18 O/ 16 O (CHON), and for the carbon samples can be solid, liquid and gas (in the form of CO 2 ) for the other elements is only possible to analyze in solid or liquid form. All samples are always analyzed separately by the destructive method. The CIE addition to performing scientific partnerships with all university, complementary and auxiliaries units of UNESP Botucatu campus also have partnerships in other academic units on campus of UNESP Jaboticabal and Dracena and Sao Paulo University in Piracicaba campus and is open to new partnerships in other research units.

    2013-09-01

    Although the perceived compatibility between one's gender and science, technology, engineering, and mathematics (STEM) identities (gender-STEM compatibility) has been linked to women's success in STEM fields, no work to date has examined how the stability of identity over time contributes to subjective and objective STEM success. In the present study, 146 undergraduate female STEM majors rated their gender-STEM compatibility weekly during their freshman spring semester. STEM women higher in gender rejection sensitivity, or gender RS, a social-cognitive measure assessing the tendency to perceive social-identity threat, experienced larger fluctuations in gender-STEM compatibility across their second semester of college. Fluctuations in compatibility predicted impaired outcomes the following school year, including lower STEM engagement and lower academic performance in STEM (but not non-STEM) classes, and significantly mediated the relationship between gender RS and STEM engagement and achievement in the 2nd year of college. The week-to-week changes in gender-STEM compatibility occurred in response to negative academic (but not social) experiences.

  7. Confidence in the Knowledge Base of English Language Learners Studying Science: Using Agency to Compensate for the Lack of Adequate Linguistic Identity

    Hayes, Aneta L.; Mansour, Nasser

    2017-04-01

    Changes in the cultural and linguistic environments of learners are often associated with identity shifts. The aim of this study was to explore what identity shifts occur when science students from Bahraini national schools transition to an international university. The role of two aspects of learner identity—that is, English proficiency and science background knowledge, was examined in this study. Focus groups and semi-structured interviews were conducted with students and with university lecturers. The analysis suggested three conceptual themes of (1) reliance on science knowledge, (2) the auxiliary role of professional language and (3) adequacy of student learning strategies, demonstrating what subjective meanings the participants ascribe to the interplay between science knowledge and linguistic ability. The findings suggest that despite the lack of adequate linguistic attributes, the students are still able to successfully learn science in the context of language change. It is also implied that through strategically utilising their academic background in science, students preserve their identity as successful learners from school through to university. We conclude that agency plays a separate role in transition and is not a sole function of identity. We also contest the idea of language as a necessary attribute of one's identity as it was perceived by our participants to be an advantage and an auxiliary tool rather than a requirement.

  8. Discursive geographies in science: space, identity, and scientific discourse among indigenous women in higher education

    Science.gov (United States)

    Brandt, Carol B.

    2008-09-01

    Despite completing undergraduate degrees in the life sciences, few Indigenous women choose to pursue careers in scientific research. To help us understand how American Indian students engage with science, this ethnographic research describes (1) how four Navajo women identified with science, and (2) the narratives they offered when we discussed their experiences with scientific discourse. Using intensive case studies to describe the experiences of these women, my research focused on their final year of undergraduate study in the life sciences at a university in southwestern US. I point to the processes by which the participants align themselves with ideas, practices, groups, or people in science. As each participant recounted her experiences with scientific discourse, they recreated for me a discursive geography of their lives on the reservation, at home, at community colleges (in some cases), and on the university campus. In the construction and analysis of the narratives for this research, mapping this geography was critical to understanding each participant's discursive relationship with science. In these discursive spaces, I observed productive "locations of possibility" in which students and their instructors: valued connected knowing; acknowledged each other's history, culture, and knowledge; began to speak to each other subject-to-subject; and challenged normative views of schooling. I argue that this space, as a location of possibility, has the power to transform the crushing impersonalized schooling that often characterizes "rigorous" scientific programs in a research institution.

  9. Effects of racialized tracking on racial gaps in science self-efficacy, identity, engagement, and aspirations: Connection to science and school segregation

    Science.gov (United States)

    Chang, Briana L.

    Given the concentration of economic growth and power in science fields and the current levels of racial stratification in schooling, this study examined (1) the effects of race on students' connectedness to science and career aspirations, (2) the extent to which these effects were moderated by school racial composition and racialized tracking, and (3) the differences in modeling effects using separate variables for race and gender (i.e., White, Black, Hispanic, female) versus race/gender (e.g., White female, Black male, etc.). Using the lens of racial formation theory, this study situated access to science knowledge as a racial project, conferring and denying access to resources along racial lines. Reviews of the literature on science self-efficacy, identity, engagement, and career aspirations revealed an under-emphasis on school institutional factors, such as racial composition and racialized tracking (which are important in sociological literature), as shaping student outcomes. The study analyzed data from the nationally representative High School Longitudinal Study that surveyed students in 2009 during their freshman year in high school and again in 2012 during most students' junior year (n = 6,998). Affective ratings (in self-efficacy, identity, engagement) and career aspirations for students measured in 2012 were examined as dependent variables and a variable for racialized tracking was estimated given schools' placement of students in advanced science coursework in 2012. Although school racial composition was not found to moderate race on outcome effects, primary analyses demonstrated that the presence of racialized tracking in the students' schools did moderate these effects. Overall these results suggested that the student subgroups most often at a disadvantage compared to White students for the science outcomes studied were Hispanic males and females; Black students' ratings and aspirations were largely on par or exceeded those of their White counterparts

    The EarthServer project (www.earthserver.eu), funded by the European Commission under its Seventh Framework Program, aims at establishing open access and ad-hoc analytics on extreme-size Earth Science data, based on and extending leading-edge Array Database technology. The core idea is to use database query languages as client/server interface to achieve barrier-free "mix & match" access to multi-source, any-size, multi-dimensional space-time data -- in short: "Big Earth Data Analytics" - based on the open standards of the Open Geospatial Consortium Web Coverage Processing Service (OGC WCPS) and the W3C XQuery. EarthServer combines both, thereby achieving a tight data/metadata integration. Further, the rasdaman Array Database System (www.rasdaman.com) is extended with further space-time coverage data types. On server side, highly effective optimizations - such as parallel and distributed query processing - ensure scalability to Exabyte volumes. Six Lighthouse Applications are being established in EarthServer, each of which poses distinct challenges on Earth Data Analytics: Cryospheric Science, Airborne Science, Atmospheric Science, Geology, Oceanography, and Planetary Science. Altogether, they cover all Earth Science domains; the Planetary Science use case has been added to challenge concepts and standards in non-standard environments. In addition, EarthLook (maintained by Jacobs University) showcases use of OGC standards in 1D through 5D use cases. In this contribution we will report on the first applications integrated in the EarthServer Science Gateway and on the clients for mobile appliances developed to access them. We will also show how federated and social identity services can allow Big Earth Data Providers to expose their data in a distributed environment keeping a strict and fine-grained control on user authentication and authorisation.

    2013-09-01

    History of science as a formal and autonomous field of research crosses over disciplinary boundaries. For this reason, both its production and its working materials are difficult to classify and catalog according to discipline-based systems of organization of knowledge. Three main problems might be pointed out in this regard: the disciplines themselves are subject to a historical process of transformation; some objects of scientific inquiry resist constraint within rigid disciplinary grids but, rather, extend across several disciplinary boundaries; and the so-called digital revolution has replaced spatial with temporal display sequences and shifted the traditional emphasis on knowledge to user-oriented approaches. The first part of this essay is devoted to a conceptual analysis of the various approaches to the organization of knowledge formulated over time, whereas the second considers the new possibilities afforded by a faceted model of knowledge organization compatible with user-oriented relational databases to the research materials and production of history of science.

  15. Tracking Identity: Opportunity, Success, and Affiliation with Science among Fifth-Grade Latina/o Youth of Santa Barbara, California

    Maas, Grayson Ford

    This dissertation is an investigation into the American public education system at the elementary school level. It highlights important factors that shape the organizational structure of schools and classrooms, and in turn, how they engender disparities in the ways students experience education, namely, in the opportunities made available to them to achieve and succeed at a high level. This dissertation operates at the confluence of notions about class, gender, language, and race, especially as they revolve around public education and the hegemonic meritocratic discourse on which it is founded. This dissertation engages and contributes to scholarship within the following areas: The political economy of education; discourse and the dialectical relationship between agency and structure; cultural perspectives on identity, voice, and learning; and, Latinas/os in science education. The data that serve as the basis for the findings presented in this dissertation were collected throughout a three-phase yearlong ethnographic study of the two tracked fifth-grade classrooms at Amblen Elementary School, serving a socioeconomically disadvantaged Latina/o student population in Santa Barbara, California. In classrooms all across the nation, while it remains true that Latina/o students disproportionally take up space in the lower-tracked courses and not in the higher ones, this study does not examine inequality in tracking assignments made along ethnic/racial lines (as 100% of the students that participated in this research identify as Latina/o), rather, it investigates the consequences of what happens when Latina/o students are tracked according to symbolic markers of their ethnic/racial identity, that is, their varying levels of English language competency. Using data from participant observation, semi-structured interviews, students' drawings, as well as free-list and rank-order exercises, I was able to answer the following central research questions: In what ways do the

    This paper examines the name as an issue of interest in the psychology field. In thinking about the role played by names for some of the most important approaches on the psychology panorama, it has been found that the analysis of names can be used as an instrument for the investigation of thought formation processes, or as an element in the process of constructing personal identity. In the first case, the focus is on the so-called "common" names, which designate objects; in the second case, instead, it is on people's given names and on the way they are perceived by their bearers and those who surround them. We have examined both domains, since it is essential to understand how the psychological concepts related to names develop in children's minds, if we aim to grasp their importance as designators of people's internal and external realities. Lastly, we have proposed our own view of the person's name, linked to the relational systems perspective which essentially sees the name as a signifier or "representative" of the child-parent relationship, while the "relationship" is the signified.

  17. Towards a 'Science of Movement': Identity, Authority and Influence in the Production of Social Stability and Social Change

    2013-12-01

    Full Text Available In this paper, we argue for social psychology as 'a science of movement'. We argue that such a science must problematise the status quo and focus on the way in which social stability as well as social change is actively produced. Key to this project is a recognition that human action arises in a context where multiple voices seek to mobilise people in different directions. The question of which voice prevails depends upon processes of social identification that provide a basis for authority and influence. We illustrate this approach, first, by examining the dynamics of crowd behaviour. We use the Elaborated Social Identity Model (ESIM to examine when people pay heed to those who advocate a challenge to authority and when, by contrast, participation increases their acceptance of existing authority. We then go on examine Milgram's famous 'obedience' studies, looking again at when participants shun the voice of authority and when they heed it. In contrast to conventional explanations which take conformity to authority as a given, we propose an 'engaged follower' perspective in which conformity depends upon identification with the cause which authority represents. We finish by showing how Milgram actively managed participants' identification in order to mobilise their compliance.

    We have followed a group of students in the potential pipeline for science through their last years of upper secondary school and in the context of a university mentorship program. The student group is defined by their choice of Mathematics at A-level which is mandatory for admission to tertiary STEM education in Denmark. Rich data (repeated interviews, questionnaires (pre-and post-) and observations) from 14 target students have been collected. Using Late Modern identity theory as a lens, we have analysed students' identity narratives in order to establish their trajectories in relation to university in general, and towards science studies and science careers in particular. We find that the diversity of students' educational identity narratives can be characterized and their trajectories understood in terms of a Four Factor Framework comprising: general identity process orientations (reflecting, committing, exploring), personal values, subject self-concepts and subject interests. In various ways these constructs interact and set the range and direction of the students' searches for future education and careers. Our longitudinal study suggests that they have enough permanence to enable us to hypothesize more or less secured paths of individual students to tertiary science (or other areas of academia).

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

    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

    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.

The statistical population included all the female students of the Faculty of Educational Sciences and Counseling of Islamic Azad University, Roudehen Branch, from among which, a sample of 36 students was selected based on the Berzonsky’s Identity Styles Inventory (ISI-6G. The subjects were divided into experimental and control groups. The content of the sessions was based on the theory of narrative therapy which was designed by the researcher and administered for 8 sessions of 60 minutes.Results: The obtained data were analyzed using analysis of covariance (ANCOVA. The results indicated that narrative therapy is effective in the decreasing of diffuse-avoidant identity style and increasing of informational style at a 0.05 level of significance.Conclusion: With regard to the results of the present research, it can be concluded that this method can be of great importance in the treatment of depressed and anxious individuals. Therefore, this treatment, with regard to its flexibility and uniqueness, the techniques that individuals use in structuring their own stories, and the confrontation of the clients with themselves and not their thoughts, may be of greater importance in the future.

    Transsexualism and other variations of gender identity are based on a stable sense of identity. The aetiology of this phenomenon is not fully known. Suffering caused by gender dysphoria is alleviated with sex reassignment. The psychiatric assessment of both adolescents and adults has been centralized in Finland to two university hospitals, the Helsinki University Hospital and Tampere University Hospital. In both hospitals, multidisciplinary teams aim at differential diagnosis by using well-known psychiatric and psychological instruments. Wishes for sex reassignment that are caused by a mental health disorder are excluded. Assessment in adolescence is challenging because the identity in youth is still forming.

  6. An ethnographic investigation of the process of change in students' environmental identity and pro-environmental behavior in an Environmental Science course

    Science.gov (United States)

    Blatt, Erica N.

    In recent years, the Environmental Science course has become increasingly integrated into the high school curriculum as a component of the core curriculum, an AP course, or as an elective (Edelson, 2007); however, little research has been conducted to evaluate the course's effectiveness in developing students' understanding of their relationship with the environment (Zelezny, 1999). Therefore, this ethnographic study at a public high school in the Northeastern United States focuses on the teacher's goals for the Environmental Science course, how students respond to the enactment of these objectives during activities in the classroom, and how the class impacts students' views of their relationship with the environment and their pro-environmental behavior. A sociocultural approach is utilized to explore how students' environmental identities, their interactions with the course content, as well as their social interactions affect their experiences in the Environmental Science classroom. The study's conceptual framework is based upon Kempton and Holland's (2003) stages of environmental identity development, as well as symbolic interactionist theories of emotion. The participants in this study are an Environmental Science teacher and the 10-12th grade students (N=17) in her semester-long elective, "Environmental Science." The researcher collected data for a period of six months during the spring semester of 2009, attending class on a daily basis. Data was collected through participant observation, videotaping, interviews, cogenerative dialogues, and various surveys. The objectives for the Environmental Science course explored in this research include the role of science content knowledge and critical thinking as students are exposed to new environmental information; developing students' emotional connection with environmental issues; influencing students' environmental behavior; and empowering students to feel that they can make a difference through their own actions

    2015-02-01

    Full Text Available This article focuses on the professional identity formation of six beginner teachers (three in early childhood education and three in the foundation phase, involved in the teaching of Mathematics, Science and Technology (MST. Attention is in particular being paid to the role of professional identity in how they applied innovative teaching methods such as enquiry-based teaching. The study is based on the personal narratives of the six teachers, regarding their own learning experiences in MST, the impact of their professional training at an institution of higher education, as well as their first experiences as MST teachers in the workplace. A qualitative research design was applied and data was obtained through visual (photo collages and written stories, observation and interviews. Whilst all the teachers held negative attitudes towards Mathematics, this situation was turned around during their university training. The three teachers in early childhood education experienced their entrance to the profession as positive, due mainly to the support of colleagues in their application of innovative teaching methods. Two teachers in the foundation phase, however, experienced the opposite. The findings emphasise the complex processes in the moulding of a professional teacher identity and how teaching practices are influenced by these processes.

  12. The influence of role-specific self-concept and sex-role identity on career choices in science

    Science.gov (United States)

    Baker, Dale R.

    Despite much effort on the part of educators the number of females who choose science careers remains low. This research focuses on two factors which may be influencing females in their choice of careers. These factors are role-specific self-concept in science and self perception in terms of stereotypical masculine and feminine characteristics. In addition logical ability and mathematics and science courses were also examined as factors in career choice. Females preferring science related careers and females preferring nontraditional careers such as police, military and trades were found to have a positive role-specific self-concept and a masculine perception of themselves. Females preferring traditional careers such as teacher or hairdresser had a poor role-specific self-concept and a more feminine perception of themselves. Males as a group were found to have a more positive role-specific self-concept than females. Logical ability was also related to a science career preference for both males and females. Males expected to take more higher level math courses than females, while females preferring science careers expected to take the most higher level science courses.

    Full Text Available Often collective identities are classified depending on their contents and rarely depending on their forms. Differentiation between soft identity and hard identity is applied to diverse collective identities: religious, political, national, tribal ones, etc. This classification is made following the principal dimensions of collective identities: type of classification (univocal and exclusive or relative and contextual, the absence or presence of conflictsof loyalty, selective or totalitarian, objective or subjective conception, among others. The different characteristics analysed contribute to outlining an increasingly frequent type of identity: the authoritarian identity.

    The primary objective of this study was to determine whether disc degeneration, as assessed through magnetic resonance imaging, is greater in smokers than in nonsmokers. To control for the maximum number of potentially confounding variables, pairs of identical twins highly discordant for cigarette smoking were selected as study subjects. Data analyses revealed 18% greater mean disc degeneration scores in the lumbar spines of smokers as compared with nonsmokers. The effect was present across the entire lumbar spine, implicating a mechanism acting systemically. This investigation demonstrates the efficiency of using carefully selected controls in studying conditions of multifactorial etiology, such as disc degeneration.

    2008-06-01

    In 2003, psychology professor and sex researcher J. Michael Bailey published a book entitled The Man Who Would Be Queen: The Science of Gender-Bending and Transsexualism. The book's portrayal of male-to-female (MTF) transsexualism, based on a theory developed by sexologist Ray Blanchard, outraged some transgender activists. They believed the book to be typical of much of the biomedical literature on transsexuality-oppressive in both tone and claims, insulting to their senses of self, and damaging to their public identities. Some saw the book as especially dangerous because it claimed to be based on rigorous science, was published by an imprint of the National Academy of Sciences, and argued that MTF sex changes are motivated primarily by erotic interests and not by the problem of having the gender identity common to one sex in the body of the other. Dissatisfied with the option of merely criticizing the book, a small number of transwomen (particularly Lynn Conway, Andrea James, and Deirdre McCloskey) worked to try to ruin Bailey. Using published and unpublished sources as well as original interviews, this essay traces the history of the backlash against Bailey and his book. It also provides a thorough exegesis of the book's treatment of transsexuality and includes a comprehensive investigation of the merit of the charges made against Bailey that he had behaved unethically, immorally, and illegally in the production of his book. The essay closes with an epilogue that explores what has happened since 2003 to the central ideas and major players in the controversy.

  19. Identity paradoxes

    Directory of Open Access Journals (Sweden)

    Đurić Jelena

    2010-01-01

    Full Text Available The article considers paradoxical nature of identity that emerges from: 1 the very concept of identity whose abstract generality unites various and even opposite features; 2 the processual nature of reality that is easier to express in the poetical metaphors or abstract principles than in unambiguous conceptual networks; 3 the oppose relationship between being and knowledge, mind and matter, subject and object, self and personality. Entangled in the labyrinth which evade efforts to be conceptually defined, the modern thinking of identity moves towards abandoning the idea of “self” on behalf of the “ego” and towards the misapprehension of identity as being identical. This corresponds to the “time of the lost spirit” stretched between the simultaneous need to find an identity and to give it up.

    Previous research has shown that the Meyerhoff Scholars Program at the University of Maryland, Baltimore County, is an effective intervention for high-achieving underrepresented minority (URM) students; African-American Meyerhoff students are significantly more likely to enter science, technology, engineering, and mathematics (STEM) PhD programs than comparison students. The first of two studies in this report extends the prior research by examining levels of PhD completion for Meyerhoff (N = 479) versus comparison sample (N = 249) students among the first 16 cohorts. Entering African-American Meyerhoff students were 4.8 times more likely to complete STEM PhDs than comparison sample students. To enhance understanding of potential mechanisms of influence, the second study used data from the 22nd (Fall 2010) to 25th (Fall 2013) cohorts (N = 109) to test the hypothesis that perceived program benefit at the end of freshman year would mediate the relationship between sense of community at the end of Summer Bridge and science identity and research self-efficacy at the end of sophomore year. Study 2 results indicated that perceived program benefit fully mediated the relationship between sense of community and both criterion measures. The findings underscore the potential of comprehensive STEM intervention programs to enhance PhD completion, and suggest mechanisms of influence. PMID:27587857

Thus, it intends to demonstrate that, on the one hand, discourse...... plays a significant role in identity construction and, on the other, that leaders’ constructions may have many sources of inspiration within and outside the organisation, emphasising that identity construction is a complex process in which organisational efforts to promote a common leadership identity...... compete with shifting subject positions, notions of self and inspirations among leaders. To support this claim, a critical discourse analysis (cf. Fairclough 2003, 2012) is carried out of interviews with two middle managers, which involves close analysis of the language used by the respondents...

    Full Text Available This article seeks to analyze, briefly, how the conception of the religious truth of Pernambuco’s kardecists, based in the modern science canons, justifies between them the development of difficult relationships with the followers of the other religions, in a time that the Catholic religion hegemony is being broken, making a plural religious situation. That way, methodologically, we tried to accomplish the exposition in a way that it was possible to intersect a discussion about the construction of the modern identity’s concept that didn’t take in consideration the difference of the Other, to a discussion on the understanding that the tolerance also had in the modernity, starting from an Eurocentric perspective. In the end, we articulate identity concepts of truth and tolerance, elaborated in the modernity time, to the spiritualistic practice, observing that this practice, when being influenced by those definitions, revealed itself very difficult on the part of the kardecists to know how to treat with respect other religious difference.

    Wrenn Mary

    2014-01-01

    Full Text Available With the intensification of neoliberalism, it is useful to examine how some individuals might cope with the irrationality of the system. Neoliberalism cloaks the execution of the corporate agenda behind rhetorical manipulation that advocates for limited government. The corollary absence of government involvement on behalf of the citizenry writ large disarms the means of social redress for the individual. Democracy funded and fueled by corporate power thereby disenfranchises the individual, provoking some to search for empowerment through identity politics. The argument set forth suggests that individuals construct, reinforce, or escalate allegiance to identities as a coping mechanism, some of which manifest in violent identity politics.

In this activity, much work had been done by the photographic emulsion technique and cloud chambers - exposed to cosmic rays as well as accelerator based beams. In fact, many if not most of the stable particles were found by these latter two techniques, however, the foree of the bubble chamber (coupled with the newer and more powerful accelerators) was to verify, and reinforce with large statistics, the existence of these states, to find some of the more difficult ones, mainly neutrals and further to elucidate their properties, i.e., spin, parity, lifetimes, decay parameters, etc. (orig.)

  4. Stable measures of number sense accuracy in math learning disability: Is it time to proceed from basic science to clinical application?

    Júlio-Costa, Annelise; Starling-Alves, Isabella; Lopes-Silva, Júlia Beatriz; Wood, Guilherme; Haase, Vitor Geraldi

    2015-12-01

    Math learning disability (MLD) or developmental dyscalculia is a highly prevalent and persistent difficulty in learning arithmetic that may be explained by different cognitive mechanisms. The accuracy of the number sense has been implicated by some evidence as a core deficit in MLD. However, research on this topic has been mainly conducted in demographically selected samples, using arbitrary cut-off scores to characterize MLD. The clinical relevance of the association between number sense and MLD remains to be investigated. In this study, we aimed at assessing the stability of a number sense accuracy measure (w) across five experimental sessions, in two clinically defined cases of MLD. Stable measures of number sense accuracy estimate are required to clinically characterize subtypes of MLD and to make theoretical inferences regarding the underlying cognitive mechanisms. G. A. was a 10-year-old boy with MLD in the context of dyslexia and phonological processing impairment and his performance remained steadily in the typical scores range. The performance of H. V., a 9-year-old girl with MLD associated with number sense inaccuracy, remained consistently impaired across measurements, with a nonsignificant tendency to worsen. Qualitatively, H. V.'s performance was also characterized by greater variability across sessions. Concomitant clinical observations suggested that H. V.'s difficulties could be aggravated by developing symptoms of mathematics anxiety. Results in these two cases are in line with the hypotheses that at least two reliable patterns of cognitive impairment may underlie math learning difficulties in MLD, one related to number sense inaccuracy and the other to phonological processing impairment. Additionally, it indicates the need for more translational research in order to examine the usefulness and validity of theoretical advances in numerical cognition to the clinical neuropsychological practice with MLD. © 2015 The Institute of Psychology, Chinese

  7. Evaluation of unique identifiers used as keys to match identical publications in Pure and SciVal - a case study from health science.

    2016-01-01

    Unique identifiers (UID) are seen as an effective key to match identical publications across databases or identify duplicates in a database. The objective of the present study is to investigate how well UIDs work as match keys in the integration between Pure and SciVal, based on a case with publications from the health sciences. We evaluate the matching process based on information about coverage, precision, and characteristics of publications matched versus not matched with UIDs as the match keys. We analyze this information to detect errors, if any, in the matching process. As an example we also briefly discuss how publication sets formed by using UIDs as the match keys may affect the bibliometric indicators number of publications, number of citations, and the average number of citations per publication.  The objective is addressed in a literature review and a case study. The literature review shows that only a few studies evaluate how well UIDs work as a match key. From the literature we identify four error types: Duplicate digital object identifiers (DOI), incorrect DOIs in reference lists and databases, DOIs not registered by the database where a bibliometric analysis is performed, and erroneous optical or special character recognition. The case study explores the use of UIDs in the integration between the databases Pure and SciVal. Specifically journal publications in English are matched between the two databases. We find all error types except erroneous optical or special character recognition in our publication sets. In particular the duplicate DOIs constitute a problem for the calculation of bibliometric indicators as both keeping the duplicates to improve the reliability of citation counts and deleting them to improve the reliability of publication counts will distort the calculation of average number of citations per publication. The use of UIDs as a match key in citation linking is implemented in many settings, and the availability of UIDs may become

    Stable isotopes are being used for forensic science studies, with applications to both natural and manufactured products. In this review we discuss how scientific evidence can be used in the legal context and where the scientific progress of hypothesis revisions can be in tension with the legal expectations of widely used methods for measurements. Although this review is written in the context of US law, many of the considerations of scientific reproducibility and acceptance of relevant scientific data span other legal systems that might apply different legal principles and therefore reach different conclusions. Stable isotopes are used in legal situations for comparing samples for authenticity or evidentiary considerations, in understanding trade patterns of illegal materials, and in understanding the origins of unknown decedents. Isotope evidence is particularly useful when considered in the broad framework of physiochemical processes and in recognizing regional to global patterns found in many materials, including foods and food products, drugs, and humans. Stable isotopes considered in the larger spatial context add an important dimension to forensic science.

    Full Text Available Communicating parties inside computer networks use different kind of identifiers. Some of these identifiers are stable, e.g., logins used to access a specific service, some are only temporary, e.g., dynamically assigned IP addresses. This paper tackles several challenges of lawful interception that emerged in modern networks. The main contribution is the graph model that links identities learnt from various sources distributed in a network. The inferred identities result into an interception of more detailed data in conformance with the issued court order. The approach deals with network address translation, short-lived identifiers and simultaneous usage of different identities. The approach was evaluated to be viable during real network testing based on various means to learn identities of users connected to a network.

    Coplen, T.B.; Qi, H.

    2012-01-01

    Because there are no internationally distributed stable hydrogen and oxygen isotopic reference materials of human hair, the U.S. Geological Survey (USGS) has prepared two such materials, USGS42 and USGS43. These reference materials span values commonly encountered in human hair stable isotope analysis and are isotopically homogeneous at sample sizes larger than 0.2 mg. USGS42 and USGS43 human-hair isotopic reference materials are intended for calibration of δ(2)H and δ(18)O measurements of unknown human hair by quantifying (1) drift with time, (2) mass-dependent isotopic fractionation, and (3) isotope-ratio-scale contraction. While they are intended for measurements of the stable isotopes of hydrogen and oxygen, they also are suitable for measurements of the stable isotopes of carbon, nitrogen, and sulfur in human and mammalian hair. Preliminary isotopic compositions of the non-exchangeable fractions of these materials are USGS42(Tibetan hair)δ(2)H(VSMOW-SLAP) = -78.5 ± 2.3‰ (n = 62) and δ(18)O(VSMOW-SLAP) = +8.56 ± 0.10‰ (n = 18) USGS42(Indian hair)δ(2)H(VSMOW-SLAP) = -50.3 ± 2.8‰ (n = 64) and δ(18)O(VSMOW-SLAP) = +14.11 ± 0.10‰ (n = 18). Using recommended analytical protocols presented herein for δ(2)H(VSMOW-SLAP) and δ(18)O(VSMOW-SLAP) measurements, the least squares fit regression of 11 human hair reference materials is δ(2)H(VSMOW-SLAP) = 6.085δ(2)O(VSMOW-SLAP) - 136.0‰ with an R-square value of 0.95. The δ(2)H difference between the calibrated results of human hair in this investigation and a commonly accepted human-hair relationship is a remarkable 34‰. It is critical that readers pay attention to the δ(2)H(VSMOW-SLAP) and δ(18)O(VSMOW-SLAP) of isotopic reference materials in publications, and they need to adjust the δ(2)H(VSMOW-SLAP) and δ(18)O(VSMOW-SLAP) measurement results of human hair in previous publications, as needed, to ensure all results on are on the same scales.

While they are intended for measurements of the stable isotopes of hydrogen and oxygen, they also are suitable for measurements of the stable isotopes of carbon, nitrogen, and sulfur in human and mammalian hair. Preliminary isotopic compositions of the non-exchangeable fractions of these materials are USGS42(Tibetan hair)δ(2)H(VSMOW-SLAP) = -78.5 ± 2.3‰ (n = 62) and δ(18)O(VSMOW-SLAP) = +8.56 ± 0.10‰ (n = 18) USGS42(Indian hair)δ(2)H(VSMOW-SLAP) = -50.3 ± 2.8‰ (n = 64) and δ(18)O(VSMOW-SLAP) = +14.11 ± 0.10‰ (n = 18). Using recommended analytical protocols presented herein for δ(2)H(VSMOW-SLAP) and δ(18)O(VSMOW-SLAP) measurements, the least squares fit regression of 11 human hair reference materials is δ(2)H(VSMOW-SLAP) = 6.085δ(2)O(VSMOW-SLAP) - 136.0‰ with an R-square value of 0.95. The δ(2)H difference between the calibrated results of human hair in this investigation and a commonly accepted human-hair relationship is a remarkable 34‰. It is critical that readers pay attention to the δ(2)H(VSMOW-SLAP) and δ(18)O(VSMOW-SLAP) of isotopic reference materials in publications, and they need to adjust the δ(2)H(VSMOW-SLAP) and δ(18)O(VSMOW-SLAP) measurement results of human hair in previous publications, as needed, to ensure all results on are on the same scales.

  18. A revision in hydrogen isotopic composition of USGS42 and USGS43 human-hair stable isotopic reference materials for forensic science

    Science.gov (United States)

    Coplen, Tyler B.; Qi, Haiping

    2016-01-01

    The hydrogen isotopic composition (δ2HVSMOW-SLAP) of USGS42 and USGS43 human hair stable isotopic reference materials, normalized to the VSMOW (Vienna-Standard Mean Ocean Water)–SLAP (Standard Light Antarctic Precipitation) scale, was originally determined with a high temperature conversion technique using an elemental analyzer (TC/EA) with a glassy carbon tube and glassy carbon filling and analysis by isotope-ratio mass spectrometer (IRMS). However, the TC/EA IRMS method can produce inaccurate δ2HVSMOW-SLAPresults when analyzing nitrogen-bearing organic substances owing to the formation of hydrogen cyanide (HCN), leading to non-quantitative conversion of a sample into molecular hydrogen (H2) for IRMS analysis. A single-oven, chromium-filled, elemental analyzer (Cr-EA) coupled to an IRMS substantially improves the measurement quality and reliability of hydrogen isotopic analysis of hydrogen- and nitrogen-bearing organic material because hot chromium scavenges all reactive elements except hydrogen. USGS42 and USGS43 human hair isotopic reference materials have been analyzed with the Cr-EA IRMS method, and the δ2HVSMOW-SLAP values of their non-exchangeable hydrogen fractions have been revised:where mUr = 0.001 = ‰. On average, these revised δ2HVSMOW-SLAP values are 5.7 mUr more positive than those previously measured. It is critical that readers pay attention to the δ2HVSMOW-SLAP of isotopic reference materials in publications as they may need to adjust the δ2HVSMOW–SLAP measurement results of human hair in previous publications to ensure all results are on the same isotope-delta scale.

  19. Biogeochemistry Science and Education Part One: Using Non-Traditional Stable Isotopes as Environmental Tracers Part Two: Identifying and Measuring Undergraduate Misconceptions in Biogeochemistry

    Science.gov (United States)

    Mead, Chris

    This dissertation is presented in two sections. First, I explore two methods of using stable isotope analysis to trace environmental and biogeochemical processes. Second, I present two related studies investigating student understanding of the biogeochemical concepts that underlie part one. Fe and Hg are each biogeochemically important elements in their own way. Fe is a critical nutrient for phytoplankton, while Hg is detrimental to nearly all forms of life. Fe is often a limiting factor in marine phytoplankton growth. The largest source, by mass, of Fe to the open ocean is windblown mineral dust, but other more soluble sources are more bioavailable. To look for evidence of these non-soil dust sources of Fe to the open ocean, I measured the isotopic composition of aerosol samples collected on Bermuda. I found clear evidence in the fine size fraction of a non-soil dust Fe source, which I conclude is most likely from biomass burning. Widespread adoption of compact fluorescent lamps (CFL) has increased their importance as a source of environmental Hg. Isotope analysis would be a useful tool in quantifying this impact if the isotopic composition of Hg from CFL were known. My measurements show that CFL-Hg is isotopically fractionated, in a unique pattern, during normal operation. This fractionation is large and has a distinctive, mass-independent signature, such that CFL Hg can be uniquely identified from other sources. Misconceptions research in geology has been a very active area of research, but student thinking regarding the related field of biogeochemistry has not yet been studied in detail. From interviews with 40 undergraduates, I identified over 150 specific misconceptions. I also designed a multiple-choice survey (concept inventory) to measure understanding of these same biogeochemistry concepts. I present statistical evidence, based on the Rasch model, for the reliability and validity of this instrument. This instrument will allow teachers and researchers to

    Several new studies have documented high rates of sexual identity mobility among young adults, but little work has investigated the links between identity change and mental health. This study uses the National Longitudinal Study of Adolescent to Adult Health (N = 11,727) and employs multivariate regression and propensity score matching to investigate the impact of identity change on depressive symptoms. The results reveal that only changes in sexual identity toward more same-sex-oriented identities are associated with increases in depressive symptoms. Moreover, the negative impacts of identity change are concentrated among individuals who at baseline identified as heterosexual or had not reported same-sex romantic attraction or relationships. No differences in depressive symptoms by sexual orientation identity were found among respondents who reported stable identities. Future research should continue to investigate the factors that contribute to the relationship between identity change and depression, such as stigma surrounding sexual fluidity. © American Sociological Association 2015.

  1. Stable convergence and stable limit theorems

    CERN Document Server

    Häusler, Erich

    2015-01-01

    The authors present a concise but complete exposition of the mathematical theory of stable convergence and give various applications in different areas of probability theory and mathematical statistics to illustrate the usefulness of this concept. Stable convergence holds in many limit theorems of probability theory and statistics – such as the classical central limit theorem – which are usually formulated in terms of convergence in distribution. Originated by Alfred Rényi, the notion of stable convergence is stronger than the classical weak convergence of probability measures. A variety of methods is described which can be used to establish this stronger stable convergence in many limit theorems which were originally formulated only in terms of weak convergence. Naturally, these stronger limit theorems have new and stronger consequences which should not be missed by neglecting the notion of stable convergence. The presentation will be accessible to researchers and advanced students at the master's level...

    Retrospective cohort. To investigate the effects of lifetime exposure to commonly suspected risk factors on disc degeneration using magnetic resonance imaging, and to estimate the effects of these suspected risk factors relative to age and familial aggregation, reflecting genetic and shared environmental influences. Structural and biochemical changes associated with disc degeneration are suspected as the underlying conditions of many back-related symptoms. Little is known about the determinants of disc degeneration. Based on lifetime discordance in suspected environmental risk factors for disc degeneration, 115 male identical twin pairs were selected. An in-depth interview was conducted of occupational and leisure time physical loading, driving, and smoking. Disc degeneration was evaluated using observational and digital magnetic resonance imaging assessment methods. Heavier lifetime occupational and leisure physical loading was associated with greater disc degeneration in the upper lumbar levels (P = 0.055 - 0.001), whereas sedentary work was associated with lesser degeneration (P = 0.006). These univariate associations did not reach statistical significance in the lower lumbar region. In multivariate analyses of the upper lumbar levels, the mean job code explained 7% of the variability in observational disc degeneration scores; the addition of age explained 16%, and familial aggregation improved the model such that 77% of the variability was explained. In the lower lumbar levels, leisure time physical loading entered the multivariate model, explaining 2% of the variability. Adding age explained 9%, and familial aggregation raised the variability in disc degeneration scores explained to 43%. The present study findings suggest that disc degeneration may be explained primarily by genetic influences and by unidentified factors, which may include complex, unpredictable interactions. The particular environmental factors studied, which have been among those most widely

    It seems to be impossible for the liberal state to embrace a Christian identity, because 'liberalism' is exactly a device for separating state and religion. Discussing the implications of a recent decision of the European Court of Human Rights, Lautsi v. Italy (2011), I argue that this is not necessarily so. If paired with a liberal commitment to pluralism, a Christian identity might even be more inclusive of minority religions than a narrowly 'liberal' state identity, which has been the dominant response in Western Europe to the challenge of immigrant diversity, especially that of Muslim origins. © London School of Economics and Political Science 2013.

    Full Text Available Earlier research has brought organizational identity to the fore as an institutional response to the developments in higher education field. Following literature, this study aims to examine the organizational identity of universities through an analysis of themes communicated at their websites. The study findings reveal that participant universities communicate five common identity themes institutionalized by higher education field. Among these themes, social values presented to the society for belongingness and capacity for enriching main university functions are found out to be most communicated themes. The findings also show that each university communicates distinct themes that still fall under these five common themes. Therefore, the study presents that distinct themes symbolizing the uniqueness claim of the university identity emerge within the pre-determined theme categories in the field.

    2014-02-01

    Full Text Available This paper examines multicultural literature as a significant and strategic object of study in response to solving national problems. In this context, multicultural literature focuses mainly on multicultural problems frequently found in literary works. One of the main issues is concerned with identity. This article examines Indonesian novels, focusing mainly on the issues of identity: (1 identity and identity problems; (2 identity articulation; (3 text representation on identity discourse in Indonesian novels. The literature sociological approach was adopted to comprehend the reality in multicultural literary texts in Indonesian novels and its relation with the phenomena of identity problems in other field of studies. The results of study indicate that the process of identity articulation and text representation on identity discourse in multicultural social phenomena deserve more serious attention. Furthermore, the problems of identity and the process of identity articulation in multicultural society also require serious attention since identity problems are closely associated with nationality. National identity is not stable but dynamic in dealing with the development of a nation. The lack of concerns on this issue may cause a serious problem of national integrity.

    2017-06-01

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

  2. Commons of Identity: Sherpa Identity Management

    Directory of Open Access Journals (Sweden)

    Leif Rune Loland

    2006-12-01

    Full Text Available The recent history of Sherpas demonstrates how identities can be scarce goods. While ‘Sherpa’ refers to an ethnic identity, ‘Sherpa’ refers to a crucial occupation in the trekking industry.i Their privileged position in Nepal’s international tourist industry is related to their common reputation. Their collective use of identity seems to help them getting access to an economic niche, and work in tourism seems to be an aspect of being Sherpa. Thus, an individual that operates in the tourist market does not only manage material assets but also identity assets to maintain the Sherpa reputation. Consequently, one can expect it to be a collective concern to husband their image, ie to control each member’s behaviour which could affect the Sherpa image. This article on Sherpa identity in encounters with outsiders analyses Sherpaness as a manageable resource that constitutes a collectively sanctioned commons. My point of departure is Barth’s analysis of ethnic boundary dynamics (1969, 1994 combined with Bourdieu’s concept of ‘capital’ and Hardin’s perspective on commons.DOI: 10.3126/dsaj.v1i0.288Dhaulagiri Vol.1 (2005 pp.176-192

Methods: The principles of an exploratory descriptive study were used. The steps of the collection included the bibliographical research directed according to the demand. An approach of the qualitative method of content analysis was carried out that fell on written narrative, language styles and intentions. After reading the entire work, the main characters were characterized and analyzed the main thematic axes: the family in a changing society; society and the crisis of identity; work as a producer and product of identities; identity crisis and domestic violence - emotional neglect. Results: The reflections included in the essay allow us to sustain the role of art and socialization as processes of constitution of individuals and societies, through social inter- actions, activities and practices, regulated by emotions, power relations and identity projects, in a dynamic between biological organisms and socio-cultural contexts. Conclusions: The work remains current because it analyzes characteristic themes of post-modern man, such as identity crisis, existential emptiness, superficiality of human relations, hopelessness of being, pessimism, lack of response, loneliness, impotence and escape.

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.

It then raises a number of points regarding the temporal locality of identity—the influence of time on issues of identity and understanding, its implications for legal interventions, social movement building, and paradigms of progressive change. As the title suggests, the paper asks us to consider the frame of identity over time.

  11. Personal Identity in Enhancement

    Full Text Available The aim of this paper is to introduce the concept of human enhancement, its methods and its relation to personal identity. Also several approaches to personal identity will be described. Transhumanism is a special think tank supporting human enhancement through modern technologies and some of its representatives claim, that even great changes to human organisms will not affect their personal identity. I will briefly describe the most important means of human enhancment and consider the problem of personal identity for each of them separately.

    This paper discusses two classes of distributions, and stochastic processes derived from them: modified stable (MS) laws and normal modified stable (NMS) laws. This extends corresponding results for the generalised inverse Gaussian (GIG) and generalised hyperbolic (GH) or normal generalised inverse...... Gaussian (NGIG) laws. The wider framework thus established provides, in particular, for added flexibility in the modelling of the dynamics of financial time series, of importance especially as regards OU based stochastic volatility models for equities. In the special case of the tempered stable OU process...

  17. Identity of psychology, identity and psychology

    Directory of Open Access Journals (Sweden)

    Mirjana Nastran Ule

    2003-09-01

    Full Text Available The article deals with epistemic issues of modern psychology with the starting hypothesis being that scientific psychology must satisfy three main interests: scientific, practical and emancipatory interest. Particularly important is the emancipatory interest, which is based on the social reflection of scientific work and conclusions. Psychological knowledge involves not only neutral descriptions of facts, but also implicit rules, expectations regarding values or norms, and criticism of undesirable behavior. The traditional psychological model attempts to satisfy the scientific interest and partly practical interest, while avoiding emancipatory interest. But I believe modern socio-historical models of psychology to be significant precisely owing to the inclusion of emancipatory interest. The difference between these two models of psychology is most obvious in their perception of identity i.e. individuality. Conventional perceptions follow the logic of "possessive individualism" in which the individual is seen as an autonomous bearer and owner of his/her psychological states and processes. The conventional model of identity supports the modernist concept of the individual as being focused on his/her self or personal identity. Socio-historical models, on the other hand, see the individual as a being embedded in social relations and social interactions, and one who builds and expresses his/her individuality through the reflection on social interactions, discursive practices, and response to the hierarchy of power and social mechanisms of control. According to this model, identity evolves through a series of social constructions which are embodied in the individual and represent him/her in society. Identity thus becomes a notion that combines individuality and social context, subjectivation and objectivation of the individual, and historical and biographical time.

  18. Plant-pollinator interactions in a biodiverse meadow are rather stable and tight for 3 consecutive years.

    Fang, Qiang; Huang, Shuangquan

    2016-05-01

    Plant-pollinator interactions can be highly variable across years in natural communities. Although variation in the species composition and its basic structure has been investigated to understand the dynamic nature of pollination networks, little is known about the temporal dynamic of interaction strength between the same plant and pollinator species in any natural community. Pollinator-mediated selection on the evolution of floral traits could be diminished if plant-pollinator interactions vary temporally. To quantify the temporal variation in plant-pollinator interactions and the interaction strength (observed visits), we compared weighted networks between plants and pollinators in a biodiverse alpine meadow in Shangri-La, southwest China for 3 consecutive years. Although plant-pollinator interactions were highly dynamic such that identical interactions only accounted for 10.7% of the total between pair years, the diversity of interactions was stable. These identical interactions contributed 41.2% of total visits and were similar in strength and weighted nestedness. For plant species, 72.6% of species were visited by identical pollinator species between pair years, accounting for over half of the total visits and three-quarters at the functional group level. More generalized pollinators contributed more connectiveness and were more central in networks across years. However, there was no similar or even opposite trend for plant species, which suggested that specialized plant species may also be central in pollinator networks. The variation in pollinator composition decreased as pollinator species numbers increased, suggesting that generalized plants experienced stable pollinator partition. The stable, tight interactions between generalized pollinators and specialized plants represent cornerstones of the studied community. © 2016 International Society of Zoological Sciences, Institute of Zoology/Chinese Academy of Sciences and John Wiley & Sons Australia, Ltd.

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

    2015-01-01

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

    Full Text Available At the time of globalization it is difficult to pretend avoiding music culture and identity from political, cultural and social developments. Thus, it is impossible for the music to be unshakable and to represent national identity by not taking and giving nothing to culture. The dynamics of life and the rapid development of technology make it impossible for the culture to remain unaffected in terms of sharing experiences social experiences. Culture represents our current course, both in terms of politics, also in the social and human aspects. Through the technology it is possible for our children to be equal with children of all other countries, to exchange information and to connect directly with all countries of the world. Musical education is one of the main factors of cultural development and preservation of national identity. Identity consists of everything we posses and reflect. We are those who distinguish from each other and have a common denominator compared to other nations.

    Philosophers concerned with the question of personal identity have typically been asking the so-called re-identification question: what are the conditions under which a person at one point in time is properly re-identified at another point in time? This is a rather technical question. In our...... everyday interactions, however, we do raise a number of personal identity questions that are quite distinct from it. In order to explore the variety of ways in which the Internet may affect personal identity, I propose in this study to broaden the typical philosophical horizon to other more mundane senses...... of the question.

    Full Text Available Kashmir has witnessed violent conflict for many years, and India has been one of the main players in this conflict. This study used the method of drawings to assess how this ongoing conflict has shaped the identities of young Muslims in Kashmir. The identities they expressed were compared with those expressed by young Muslims in Delhi. At each location, one group of participants was asked to draw on the theme “Me and my country” while the other group was asked to draw whatever they desired. When allowed to draw what they wished, adolescents in Kashmir drew symbols of regional identity more often and symbols of India less often than adolescents in Delhi. “I dominant” identities were depicted only by the Delhi-based sample. Drawings from Kashmir did not represent high levels of violence or a fractured relationship with the Indian state. Possible reasons have been discussed.

  11. Historical and contemporary stable isotope tracer approaches to studying mammalian protein metabolism

    Science.gov (United States)

    2016-01-01

    Over a century ago, Frederick Soddy provided the first evidence for the existence of isotopes; elements that occupy the same position in the periodic table are essentially chemically identical but differ in mass due to a different number of neutrons within the atomic nucleus. Allied to the discovery of isotopes was the development of some of the first forms of mass spectrometers, driven forward by the Nobel laureates JJ Thomson and FW Aston, enabling the accurate separation, identification, and quantification of the relative abundance of these isotopes. As a result, within a few years, the number of known isotopes both stable and radioactive had greatly increased and there are now over 300 stable or radioisotopes presently known. Unknown at the time, however, was the potential utility of these isotopes within biological disciplines, it was soon discovered that these stable isotopes, particularly those of carbon (13C), nitrogen (15N), oxygen (18O), and hydrogen (2H) could be chemically introduced into organic compounds, such as fatty acids, amino acids, and sugars, and used to “trace” the metabolic fate of these compounds within biological systems. From this important breakthrough, the age of the isotope tracer was born. Over the following 80 yrs, stable isotopes would become a vital tool in not only the biological sciences, but also areas as diverse as forensics, geology, and art. This progress has been almost exclusively driven through the development of new and innovative mass spectrometry equipment from IRMS to GC‐MS to LC‐MS, which has allowed for the accurate quantitation of isotopic abundance within samples of complex matrices. This historical review details the development of stable isotope tracers as metabolic tools, with particular reference to their use in monitoring protein metabolism, highlighting the unique array of tools that are now available for the investigation of protein metabolism in vivo at a whole body down to a single protein level

It takes the form of a review article with two areas: the identity as an object of study in the Social Sciences and discourse analysis as an analytical perspective, which will be placed on dialogue as from empirical studies that applied it, including my Thesis in Social Sciences. Recognizing the diversity of perspectives that make up the field of discourse analysis, we seek to provide an organizational scheme of the main theories of discourse used in the current identity studies.

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

    Full Text Available Earlier studies have shown variation among experimental attempts to establish whether human monozygotic twins that are genetically identical also have identical individual scents. In none of the cases were the dogs able to distinguish all the individual scents of monozygotic twins living in the same environment if the scents were presented to them separately. Ten specially trained police German Shepherd dogs of three Czech Republic Police Regional Headquarters were used for scent identification in our study. The dogs were supposed to match scents of two monozygotic pairs (5 and 7 years old and two dizygotic twin pairs (8 and 13 years old. Scents were collected on cotton squares stored in glass jars. Dog handlers were blind to the experiment details. In each trial (line-up, one scent was used as a starting scent and the dog was then sent to determine if any of the 7 presented glass jars contained a matching scent. Scents of children of similar ages were used as distractors. In the matching procedure, the dogs matched correctly the scent of one twin with the other, as well as two scents collected from every single identical and non-identical twin to prove their efficacy and likewise, the presence of the matching twin scent in any given glass jar. All dogs in all trials distinguished correctly the scents of identical as well as non-identical twins. All dogs similarly matched positively two scents collected from the same individuals. Our findings indicated that specially trained German Shepherd dogs are able to distinguish individual scents of identical twins despite the fact that they live in the same environment, eat the same food and even if the scents are not presented to them simultaneously.

  2. The European Identity

    Full Text Available European identity is not only a scientifically interesting question, but also a politically important issue: in fact, sixty years after the signing of the Treaty of Rome, the European Union finds itself for the first time facing risks that threaten its own existence. The European Union is a limited and incomplete project because Europe’s economic integration has not been accompanied by a genuine supranational political union and greater cultural integration. The deficit of democratic representation and cultural integration is due to the fact that the community process is based only on economic rationality and not on a feeling of common belonging. In the current situation in which the Union faces difficult challenges which threaten to undermine the future, it necessary to affirm the policy of interests with a policy of identity. In this essay, we will first concentrate on the concept of identity – that is on the nucleus of values and common institutions –; then we will discuss how the European identity has changed over time (also in relation to national identities and what are the mechanisms that may favour its taking root in the current situation. The European project of political unification needs to be re-emphasized, finding the way to a European collective identity, not contrasted with but alongside the different national identities, referring to loyalty and shared commitment to a whole collection of cultural values: fundamental human rights, civil liberties, democratic political institutions, rule of law, freedom of movement of people, goods and capital, social justice and non-violent resolution of conflicts.

    Physician has to know the patient in the disease and not only the disease in the patient, from the dual perspective of the body as object and the body as subject. This also affects the patient who has to cope with the reality of having a body that bursts into the subject's consciousness as a vital threat, as source of discomfort and inability and being a body (Marcel). The human body in its dual aspect has been and is a great unknown, if not a great outrage in spite of the fact that we are our body and our body is each of us. We sometimes do not feel as we are and thus a confrontation arises, sometimes more normal, others more morbid. This forces the physician to face complex ethics considerations and the scientist to accept a personal identity disorder. Dualism considers that there are two substances in us, one that distinguishes us from other beings and from the rest of the individuals of the human species, the soul, the psychic life, mind or consciousness, and another more insubstancial one, the body. The aim of the first substance is to dominate the body, to survive it after death when it is, already a corpse is meant to become putrefied, is buried, incinerated or thrown to the depth of the sea. This dualism aims to explain the origin of the evil and the attitude to defeat it and it does so efficiently. This anthropology has very ancient roots (the Upvanishads, in the orphic texts, in Plato), it is the core of Gnostic thought and the foundation of the modern science since Descartes. Some monist perspectives are a masked dualism or a mereologic fallacy, according to which, the brain is conscious, when that what is conscious is the subject, although the subject, with the brain could not be conscious. Therefore, a new perspective is proposed, chiasmatic or janicular monism, that considers the adaptive value of focusing on the reality from two perspectives, as physical universe and the world of interpersonal relationships.

From the outdated stereotype of white, heterosexual, teenage boys playing Nintendo in their parents’ basement to the equally contested proclamation that “‘gamers’ are over”, the current game culture climate is such that movements as divisive and controversial as #gamergate can flourish.

    Federated identity management (FIM) is an arrangement that can be made among multiple organisations that lets subscribers use the same identification data to obtain access to the secured resources of all organisations in the group. Identity federation offers economic advantages, as well as convenience, to organisations and their users. For example, multiple institutions can share a single application, with resultant cost savings and consolidation of resources. In order for FIM to be effective, the partners must have a sense of mutual trust. A number of laboratories including national and regional research organizations are facing the challenge of a deluge of scientific data that needs to be accessed by expanding user bases in dynamic collaborations that cross organisational and national boundaries. Driven by these needs, representatives from a variety of research communities, including photon/neutron facilities, social science & humanities, high-energy physics, atmospheric science, bioinformatics and fusi...

  14. Hemifield effects in multiple identity tracking.

    Directory of Open Access Journals (Sweden)

    Charlotte Hudson

    Full Text Available In everyday life, we often need to attentively track moving objects. A previous study has claimed that this tracking occurs independently in the left and right visual hemifields (Alvarez & Cavanagh, 2005, Psychological Science,16, 637-647. Specifically, it was shown that observers were much more accurate at tracking objects that were spread over both visual hemifields as opposed to when all were confined to a single visual hemifield. In that study, observers were not required to remember the identities of the objects. Conversely, in real life, there is seldom any benefit to tracking an object unless you can also recall its identity. It has been predicted that when observers are required to remember the identities of the tracked objects a bilateral advantage should no longer be observed (Oksama & Hyönä, 2008, Cognitive Psychology, 56, 237-283. We tested this prediction and found that a bilateral advantage still occurred, though it was not as strong as when observers were not required to remember the identities of the targets. Even in the later case we found that tracking was not completely independent in the two visual hemifields. We present a combined model of multiple object tracking and multiple identity tracking that can explain our data.

    Full Text Available This paper is a continuation of a study on regionalisation and family, within the project named Sociological Aspects of Multiculturality and Regionalisation and their influence on the development of AP Vojvodina and the Republic of Serbia. The author focuses her attention to operationalisation of the theoretical and methodological premises that were developed in the previous paper (Tripković, 2002: 111-127, which means that it represents the results of the second phase of the research plan. This phase includes adjusting of theoretical concepts to the fieldwork displaying the results of the research and the analysis of the findings that put a family in the context of confronting different identities, above all national and regional. As possible "identity difference" was emphasized in the research, theoretical and methodological apparatus was adjusted to this goal. That is why in this paper the replies of interviewees that can suggest or reject the assumption that their national identity can influence significantly the evaluation of identity specificities are presented and analyzed, concerning more or less visible aspects of family life, like welfare status, relations between spouses, respect to the elder, family harmony, number of children, connections with relatives, etc.

    Full Text Available The relationship between language and identity is widely discussed in applied linguistics, sociology, communications and other related scholarly fields. Furthermore, many researchers have focused on the post-Soviet region, which given its unique historical context allows for testing of this relationship. The widespread bilingualism as a result of historical russification and the linguistic transformations that occurred after the collapse of the Soviet Union make the region a ‘sociolinguistic playground’. Recent events in Ukraine have given grounds to further explore this relationship, now in attempt to link language and identity as potential forces for geopolitical change in the region. This paper presents an overview of existing research, theories, and opposing perspectives related to the relationship between language and identity, and considers complications such as historical russification, religious influence, socioeconomic factors, and education with regards to the Ukrainian and post-Soviet context.  I aim to illustrate the significance of language and its effects on socio-political change in the case of Ukraine, by presenting arguments and complications in support of the relationship between language and identity.

    Full Text Available The ambition of this issue of Portal is to reach across the methodological boundaries of history, politics, literature and geography to apply their complementary perspectives to the study of identity and its relation to space and place, an aim that involves attempting to identify the many different ways the notoriously slippery concepts of identity and geography may intersect. For this issue we have selected articles that cast a fresh perspective on two areas where identity and geography intersect: the construction of identity through the imaginative recreation of place in literature: Mapping Literary Spaces; and the study of the shifting relationships of centre and periphery, exclusion and inclusion in urban settings and geopolitical confrontations: Social and Political Peripheries. Gerard Toal has written that geography is not a noun but a verb: it does not describe what space is but studies what we do with space, imaginatively and politically. The articles in this issue illustrate the exercise of the literary and political imagination and the role of materiality and memory in the creation of geographic representation. They show too a new awareness of the centrality of space in the constitution of identities, and the need for a new geocritical reading of its discourse, as the interrelations of place and community are played out on the many scales of social and political life, from the local to the global.   The special issue is organised thus: Introduction Matthew Graves (Aix-Marseille University & Liz Rechniewski (Sydney University: “Imagining Geographies, Mapping Identities.” I.

  8. Rights of Identity

    Daniel Kofman

    2017-01-01

    Full Text Available A person’s identity is their sense of who and what they are, of who stands in significant relations to them, and of what is valuable to them. This is inevitably very broad, an immediate implication of which is that the concept of identity taken alone cannot do significant normative work. In some cases a person’s identity is bound up with the evil that they do or wish to do, and cannot thereby give them any right to do it. In other cases very powerful elements of a person’s identity – such as their attachment to loved ones – is certainly related to important rights, but it is not entirely clear that one needs the concept of identity to explicate or justify these rights; the deep involvement of their identity is arguably a byproduct of other important values in these cases (such as love, and those values can do the grounding work of the rights by themselves and more simply and clearly. Nevertheless, when suitably qualified, a person’s identity is central to accounting for important political rights. These ranges from rights to participate in cultural practices of one’s group, which sometimes implies duties on governments to support minorities threatened with extinction, to – at the outer limit – rights to arrange political administration. These rights are connected to both autonomy and fairness. Cultural rights are often taken either to be opposed to autonomy, or at best instrumental to personal autonomy (by providing ‘options’, but in fact, the ideal of autonomy, expressed by Mill as being the author of one’s life, requires that one be in control of significant aspects of one’s identity. Significant aspects of one’s identity are collectively determined within a culture. Cultures are not static, and their development is particularly affected by political boundaries. A fundamental right of autonomy implies, therefore, that groups be allowed, within reasonable constraints of general feasibility and stability, to arrange

  11. Developing a workable teacher identity: Building and negotiating identity within a professional network

    Science.gov (United States)

    Rostock, Roseanne

    The challenge of attracting and retaining the next generation of teachers who are skilled and committed to meeting the growing demands of the profession is of increasing concern to researchers and policy makers, particularly since 45--50% of beginning teachers leave the profession within five years (Ingersoll & Smith, 2003). Reasons for such attrition include compensation, status and working conditions; however, there is growing evidence that a critical factor in new teacher retention hinges on teachers' ability to accomplish the difficult task of forming a workable professional identity in the midst of competing discourses about teaching (Alsup, 2006; Britzman, 2003). There is little research on professional identity development among those beginning teachers at highest risk for attrition (secondary math and science teachers, and those with strong academic backgrounds). This study explores the professional identity development of early-career math and science teachers who are part of the Knowles Science Teaching Foundation's (KSTF) teaching fellowship program, an external support network that aims to address many of the issues leading to high attrition among this particular population of teachers. Using narrative research methods, I examine three case studies of beginning teachers, exploring how they construct professional identity in relation to various discourse communities and negotiate tensions across multiple discourses. The cases identify both dominant discourses and counter-discourses that the teachers draw upon for important identity development resources. They also demonstrate that the way a teacher manages tensions across competing discourses is important to how well one can negotiate a workable professional identity. In particular, they emphasize the importance of engaging in borderland discourses (Gee, 1996) as a way of taking agency in one's own identity development as well as in transforming one's discourse communities. These cases shed light on how

  12. Tempered stable distributions stochastic models for multiscale processes

    CERN Document Server

    Grabchak, Michael

    2015-01-01

    This brief is concerned with tempered stable distributions and their associated Levy processes. It is a good text for researchers interested in learning about tempered stable distributions.  A tempered stable distribution is one which takes a stable distribution and modifies its tails to make them lighter. The motivation for this class comes from the fact that infinite variance stable distributions appear to provide a good fit to data in a variety of situations, but the extremely heavy tails of these models are not realistic for most real world applications. The idea of using distributions that modify the tails of stable models to make them lighter seems to have originated in the influential paper of Mantegna and Stanley (1994). Since then, these distributions have been extended and generalized in a variety of ways. They have been applied to a wide variety of areas including mathematical finance, biostatistics,computer science, and physics.

    2012-01-01

    Thermonuclear X-ray bursts result from unstable nuclear burning of the material accreted on neutron stars in some low mass X-ray binaries (LMXBs). Theory predicts that close to the boundary of stability oscillatory burning can occur. This marginally stable regime has so far been identified in only a small number of sources. We present Rossi X-ray Timing Explorer (RXTE) observations of the bursting, high- inclination LMXB 4U 1323-619 that reveal for the first time in this source the signature of marginally stable burning. The source was observed during two successive RXTE orbits for approximately 5 ksec beginning at 10:14:01 UTC on March 28, 2011. Significant mHz quasi- periodic oscillations (QPO) at a frequency of 8.1 mHz are detected for approximately 1600 s from the beginning of the observation until the occurrence of a thermonuclear X-ray burst at 10:42:22 UTC. The mHz oscillations are not detected following the X-ray burst. The average fractional rms amplitude of the mHz QPOs is 6.4% (3 - 20 keV), and the amplitude increases to about 8% below 10 keV.This phenomenology is strikingly similar to that seen in the LMXB 4U 1636-53. Indeed, the frequency of the mHz QPOs in 4U 1323-619 prior to the X-ray burst is very similar to the transition frequency between mHz QPO and bursts found in 4U 1636-53 by Altamirano et al. (2008). These results strongly suggest that the observed QPOs in 4U 1323-619 are, like those in 4U 1636-53, due to marginally stable nuclear burning. We also explore the dependence of the energy spectrum on the oscillation phase, and we place the present observations within the context of the spectral evolution of the accretion-powered flux from the source.

  14. Scripting Professional Identities

    This article examines how individual accountants subjectively interpret competing logics of professionalism as they transform from practicing accountants to managerial roles and as their organizations transform from traditional professional partnerships to more corporate organizational forms. Based...... on a longitudinal ethnography of professionals in a Big Four accounting firm we analyse the process by which individual professionals make sense of their new roles and integrate the conflicting demands of professional and managerial logics. We find that individuals are active authors of their own identity scripts....... We further observe considerable interpretive variation in how identity scripts are reproduced and enacted. We contribute to the emerging understanding of institutions as ‘inhabited’ by individuals and extend this literature by demonstrating that the institutional work of reinterpreting competing...

  15. Implicit self and identity.

    Devos, Thierry; Banaji, Mahzarin R

    2003-10-01

    Recent advances in research on implicit social cognition offer an opportunity to challenge common assumptions about self and identity. In the present article, we critically review a burgeoning line of research on self-related processes known to occur outside conscious awareness or conscious control. Our discussion focuses on these implicit self-related processes as they unfold in the context of social group memberships. That is, we show that group memberships can shape thoughts, preferences, motives, goals, or behaviors without the actor's being aware of such an influence or having control over such expressions. As such, this research brings to the fore facets of the self that often contrast with experiences of reflexive consciousness and introspection. Far from being rigid or monolithic, these processes are highly flexible, context-sensitive, and deeply rooted in socio-structural realities. As such, work on implicit self and identity renew thinking about the interplay between the individual and the collective.

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

    John Locke speaks of personal identity and survival of consciousness after death. A criterion of personal identity through time is given. Such a criterion specifies, insofar as that is possible, the necessary and sufficient conditions for the survival of persons. John Locke holds that personal identity is a matter of psychological continuity. He considered personal identity (or the self) to be founded on consciousness (viz. memory), and not on the substance of either the soul or the body.

    This study examines science interests, efficacy, attitudes, and identity—referred to as affinities, in the context of an informal science outreach program for girls. A mixed methods design was used to explore girls' science affinities before, during, and after participation in a cohort-based summer science camp. Multivariate analysis of survey data revealed that girls' science affinities varied as a function of the joint relationship between family background and number of years in the program, with girls from more affluent families predicted to increase affinities over time and girls from lower income families to experience initial gains in affinities that diminish over time. Qualitative examination of girls' perspectives on gender and science efficacy, attitudes toward science, and elements of science identities revealed a complex interplay of gendered stereotypes of science and girls' personal desires to prove themselves knowledgeable and competent scientists. Implications for the best practice in fostering science engagement and identities in middle school-aged girls are discussed.

    Space activities are one particularly visible area, where Europe can shape its identity. This publication investigates the effect space activities have already had on building a European “spirit” (e.g. through European missions or European astronauts). It also looks into the effects that activities labelled “national” have on the emergence of a European identity. Based on this analysis, the book's intention is to identify creative ways and means for how to further use space for shaping the European identity. For this purpose the focus is not only on policy analysis but also on expertise from the fields of cultural science and the arts in order to tap their creative potential and also their theoretical approaches to the topic. Selecting this theme provides ESPI with another opportunity to develop its trans-disciplinary approach.

    Full Text Available This is an essay on the issue of the identity of the Brazilian youth related to risks in our contemporary culture. There is a brief approach towards conceptual dimensions connected to categories such as ‘health’, ‘contemporaneity’, ‘identity’, ‘youth’. Some statistical aspects related to morbidity and mortality are presented in order to generate a synthetic framework of the epidemiological situation in our context. An analysis is proposed, from a sociological point of view, concerning the construction of fluid identities in a society characterized by precariousness and excess in many levels. At last, it is suggested how the link between risk and ambivalence in many ways frame respective attitudes of exposure (adventure and avoidance (prevention. Keywords: risk, identity, youth, social sciences in health.

  8. Stability and change in sexual orientation identity over a 10-year period in adulthood.

    Mock, Steven E; Eibach, Richard P

    2012-06-01

    We examined reports of sexual orientation identity stability and change over a 10-year period drawing on data from the National Survey of Midlife Development in the United States (MIDUS I and II) and tested for three patterns: (1) heterosexual stability, (2) female sexual fluidity, and (3) bisexual fluidity. Fifty-four percent of the 2,560 participants were female and the average age was approximately 47 years. At Wave 1, 2,494 (97.42%) reported a heterosexual identity, 32 (1.25%) a homosexual identity, and 34 (1.33%) a bisexual identity and somewhat more than 2% reported a different sexual orientation identity at Wave 2. Although some support for each hypothesis was found, initial sexual orientation identity interacted with gender to predict a more complex pattern. For the sample as a whole, heterosexuality was the most stable identity. For women, bisexuality and homosexuality were equally unstable and significantly less stable than heterosexuality, suggesting that sexual orientation identity fluidity is a pattern that applies more to sexual minority women than heterosexual women. For men, heterosexuality and homosexuality were both relatively stable compared to bisexuality, which stood out as a particularly unstable identity. This pattern of results was consistent with previous findings and helps to address methodological limitations of earlier research by showing the characteristics of a population-based sample of heterosexual, homosexual, and bisexual identified men and women over time.

    Pure deuterium has been separated from gaseous mixtures of hydrogen and deuterium by band displacement chromatography, using columns of palladium on a support. The best results were obtained with columns of Pd on sintered α alumina. With a column of this type, of total capacity about 2 liters, a preparative apparatus of low dead volume has been built which produces 1 liter of pure D 2 from a 50 p. 100 D 2 , 50 p. 100 100 H 2 mixture in about 12 minutes. As a first approximation chromatography is likened theoretically to counter current fractionation, neglecting superficial resistance to the exchange. and also longitudinal diffusions. The number of theoretical plates required necessary for a certain enrichment of the gas phase is determined graphically or by calculation, enabling comparisons to be made between the efficiencies of columns containing different amounts of palladium. Thermal Diffusion: For the separation of hydrogen isotopes a thermal diffusion installation, made of stainless steel and entirely tele-commanded has been constructed. The separation cascade is made up of two identical pairs of hot wire columns. Each pair can work separately or they may be connected by a thermosyphon. The temperature of the hot wire is kept at around 1000 deg C by direct current. With this installation, hydrogen samples with a deuterium content lower than o,5 ppm were obtained from a gas originally containing 32 ppm. It was thus possible to prepare tritium of 99,3 p. 100 concentration from gas with an initial content of 6 p. 100. For quantitative separation of xenon enriched five time in 124 Xe by thermal diffusion, two identical cascades were constructed, each consisting of 5 columns, working in parallel and the two being connected by thermosyphon or by a capillary tube linked to a thermal gas oscillation. The central tungsten wire is heated to 1200 deg C. The columns are grouped like cluster of a heat exchanger, in shell of 30 cm diameter through which cooling water

Given the negative stigma attached to the category of «immigrant», not all recognise themselves as such. Some simply refuse to acknowledge they belong to this category, while others use the projection of prejudices on immigrants towards Spaniards as a strategy from which they distance themselves by establishing a distinction between Catalans and Spaniards.

    The paper discusses the concept of identity in relation to management. We take our starting point in Wittgenstein’s concept language games. We argue that identity is a question of using linguistic tools to construct reality. Two elements of the language game metaphor are central here: rules...... and family resemblance. As such, managing identity in organizations is closely linked to rules and family resemblance. Organizations manage identity through the definition of norms and values for right or wrong, appropriate or inappropriate, to name but a few. Norms and values are important as reference...... points for constructing identities. Managing identity has become more important because the rules-of-the-game have become more unstable. Managing identity is important if the bonds between individuals and organizations are to be sustained. But this task is contradictory and paradoxical of its very nature...

  16. Identity style and coping strategies.

    Berzonsky, M D

    1992-12-01

    This study examined the relationship between identity style and strategies used to cope with stressors that potentially threaten one's sense of identity. Identity style refers to differences in the way individuals construct and revise or maintain their sense of identity. An informational style involves actively seeking out, evaluating, and utilizing self-relevant information. A normative style highlights the expectations and standards of significant others. A diffuse/avoidant style is characterized by procrastination and situation-specific reactions. Late-adolescent college subjects were administered measures of identity style, ways of coping with academic stressors, and test anxiety. Within this self-as-student context, subjects with diffuse and normative identity styles employed avoidant-oriented coping strategies (wishful thinking, distancing, and tension reduction). An informational style was associated with deliberate, problem-focused coping. Findings are discussed in terms of a process model of identity development.

Moreover, we consider the event that the paths of standard MSP hit some x \\in R twice and we give a sufficient condition for a positive probability of this event.

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

  8. Host Identity Protocol Proxy

    Salmela, Patrik; Melén, Jan

    The Host Identity Protocol (HIP) is one of the more recent designs that challenge the current Internet architecture. The main features of HIP are security and the identifier-locator split, which solves the problem of overloading the IP address with two separate tasks. This paper studies the possibility of providing HIP services to legacy hosts via a HIP proxy. Making a host HIP enabled requires that the IP-stack of the host is updated to support HIP. From a network administrator's perspective this can be a large obstacle. However, by providing HIP from a centralized point, a HIP proxy, the transition to begin using HIP can be made smoother. This and other arguments for a HIP proxy will be presented in this paper along with an analysis of a prototype HIP proxy and its performance.

  10. Nostalgia and lost identity.

    Science.gov (United States)

    Pourtova, Elena

    2013-02-01

    Nostalgia for the Soviet Union is a major social phenomenon in Russia today due to the irrevocable losses of the recent past in which Soviet citizens involuntarily became immigrants in their own country. With reference to discussions of nostalgia in philosophical and psychoanalytic literature, I suggest that nostalgia may represent either a defensive regression to the past or a progressive striving for wholeness through re-connecting with what has been lost in the service of a greater integration. I compare this with the processes of adaptation seen in immigrants and provide a clinical illustration of a young man coming to terms with loss and change in the post-Soviet era. When nostalgia is recognized as a legitimate emotional experience it may facilitate mourning and enable the integration of the past with the present and the development of a new identity. © 2013, The Society of Analytical Psychology.

  15. Just like my nanny: troubling teacher's social identities in the classroom

    2013-06-01

    Teacher-researcher narrative accounts are essential and insightful for the science education field, yet they are few and far-between. In this forum, I engage in dialogue with Nicole Grimes's auto-ethnographic narrative on the affordances her femme-Carribean identity allowed for some students to engage more deeply in science. While I agree with and applaud Grimes's reflection on how her perceived social identity had positive effects on some students' engagement in science, I trouble the notion of such a social identity being framed solely as an asset to student learning by examining the power dynamics inherent in the enacted nanny-child relationship. I also propose the need for deeper analyses on how a teacher's social identity can impact students' learning experiences in the science classroom by looking at how the boundaries of the science classroom are redefined and what additional resources are recruited that can foster deeper engagement.

    2017-01-01

    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.

    This article is part of a Special Issue "Puberty and Adolescence".This article aims to provide an outline of what is currently known on trajectories, and contributing factors to gender identity development in adolescence. We give a historical overview of the concept of gender identity, and describe general identity development in adolescence, gender identity development in the general population and in gender variant youth. Possible psychosocial (such as child and parental characteristics) and biological factors (such as the effects of prenatal exposure to gonadal hormones and the role of genetics) contributing to a gender variant identity are discussed. Studies focusing on a number of psychosocial and biological factors separately, indicate that each of these factors influence gender identity formation, but little is known about the complex interplay between the factors, nor about the way individuals themselves contribute to the process. Research into normative and gender variant identity development of adolescents is clearly lagging behind. However, studies on persons with gender dysphoria and disorders of sex development, show that the period of adolescence, with its changing social environment and the onset of physical puberty, seems to be crucial for the development of a non-normative gender identity.

    Full Text Available It is characteristic of much professional work that it is performed in ambiguous contexts. Thus, uncertainty, unpredictability, indeterminacy, and recurrent organizational transformations are an integral part of modern work for, e.g., engineers, lawyers, business consultants, and other professionals. Although key performance indicators and other knowledge management systems are used to set standards of excellence for professionals, the character of professional work is still flexible, open to interpretation and heterarchical. The very successfulness (or unsuccessfulness of the work is established in a complex work context where various goals, interests, and perspectives are mediated, altered, contested, mangled, and negotiated in a process of sense-making. The work context is heterogeneously populated by various actors (e.g., the customer, the manager, the colleagues and actants (e.g., quality systems and technical equipment that give “voice” to (conflicting interpretations of what constitutes successful work. Thus, the professionals must navigate in a very complex environment where the locus of governance is far from stable. These characteristics of professional work seem to have implications for the way professionals make sense of their work and their own identities. The identity work of professionals is interwoven with their professional training and career background. With an academic training and a professional career, the individual typically identifies with the profession’s values and adopts a certain way of seeing and approaching the world. This professional outlook typically will constitute the basis of the individual’s appraisal of the work and lay out a horizon of expectations in relation to fulfillment, self-realization, and job satisfaction. In this way, the construction of self-identity becomes the yardstick for the individual’s sense-making and, a fortiori, for the individual’s sense of meaningful work. In this paper

    2016-08-01

    Full Text Available The present article sets out to clarify the concepts of storytelling and branding, with a focus on university branding and visual identity – the latter being a vital element to a brand’s uniqueness. Storytelling is an important method of brand construction, and it entails a strong power of seduction. Branding is increasingly more about storytelling. Practically, a story is an image made up of facts, feelings and interpretations, which are often told to us solely by the university itself. As such, the brand appears on the market accompanied by its identity. Identity is what we aim to express with help of the brand. Implementing a system of visual identity that would help to harmoniously develop a university brand requires a handbook of visual identity. The present article aims to be a starting point for such a handbook serving the University of Bucharest, which currently does not own such a handbook

    Full Text Available The aim of this article is to understand the relationship between ethnic identity, victimization/witnessing community violence, ethnic discrimination, and aggression in a sample of university students living in the South East Region of Turkey. The participants were 263 university students of predominantly Kurdish ethnic origin. The results showed that males had higher levels of ethnic identity in the dimensions of exploration and commitment. Males also presented higher scores for witnessing community violence and lifetime exposure to ethnic discrimination. The most important predictor of participants’ ethnic identity was witnessing community violence. Participants who witnessed violent acts in their social environment had higher ethnic identity levels. Although the predictor variables could not explain an important part of the participants’ aggression levels, only perceived ethnic discrimination was positively related to aggressive behavior. The role of native language efficiency in ethnic identity is also discussed.

    Full Text Available The article is devoted to the development of the modern politics of identity construction in Japan, which actively refers to the practice of designing self-image in international relations. This trend dates back to the 19th century, when there was the end of Sakoku (Japan’s policy of isolation. It is now possible to talk about the institutionalization of the identity construction policy to organized structures and regulations. Enhanced efforts in the field of Japanese traditional and popular culture, education and creative content has led to a number of institutions appearance (like Japan Foundation Fund, Japan Creative Agency, Japan Culture Fund, Agency for Cultural Affairs, Cool Japan Fund, Japan brand Fund and changing idea about the role of culture in foreign policy realization (it is fixed the documents of the Japanese Ministry of Foreign Affairs, the Ministry of Land, Infrastructure, Transport and Tourism, the Ministry of Education, Culture, Sports, Science and Technology, the Ministry of Economy, Trade and Industry, as well as a number of projects (Cool Japan, Visit Japan, Japan Culture Power, Japan Manga Awards, Kawaii Ambassadors, Cosplay International Fest and etc.. These efforts are aimed at forming Japan identity abroad to solve a number of foreign policy challenges of the future and the development of economic cooperation. The Japanese government nearest plans is to increase funding in order to create a positive image of Japan in the region of East Asia. All of these allows us to speak about the policy of the Japanese construction of identity as an institutionalized process in which there was clearance of organizations and regulatory activities.

    Research purpose: The main aim of this study was to explore employee narratives and identify the strategies available to them in the process of identity work, as they defined themselves at work. Motivation for the study: As there is a scarcity of research on identity work in South Africa, this study wanted to advance knowledge about identity work and the strategies used for regulating and negotiating an identity at work by exploring these constructs in this context. Research design, approach and method: A qualitative research process formed the basis for this study. Nineteen employees from a global manufacturing company participated in two semi-structured in-depth interviews. Grounded theory was applied to analyse and interpret the data. Main findings: Nine strategies for identity work were identified and categorised into four broad themes (personal philosophies; relationships; career management and negotiating balance. Practical/managerial implications: Employees followed various strategies for defining themselves at work and this may have some implications for employee work engagement and productivity. Contribution/value-add: This study expands on current theoretical knowledge of identity work, and provides insights into the strategies people use to regulate and negotiate their identities at work.

Subjects suffering from BIID have an intense desire to amputate a major limb or severe the spinal cord in order to become paralyzed. Aim of the study is to broaden the knowledge of BIID amongst medical professionals, by describing all who deal with BIID. METHODS: Somatic, psychiatric and BIID characteristic data were collected from 54 BIID individuals using a detailed questionnaire. Subsequently, data of different subtypes of BIID (i.e. wish for amputation or paralyzation were evaluated. Finally, disruption in work, social and family life due to BIID in subjects with and without amputation were compared. RESULTS: Based on the subjects' reports we found that BIID has an onset in early childhood. The main rationale given for their desire for body modification is to feel complete or to feel satisfied inside. Somatic and severe psychiatric co-morbidity is unusual, but depressive symptoms and mood disorders can be present, possibly secondary to the enormous distress BIID puts upon a person. Amputation and paralyzation variant do not differ in any clinical variable. Surgery is found helpful in all subjects who underwent amputation and those subjects score significantly lower on a disability scale than BIID subjects without body modification. CONCLUSIONS: The amputation variant and paralyzation variant of BIID are to be considered as one of the same condition. Amputation of the healthy body part appears to result in remission of BIID and an impressive improvement of quality of life. Knowledge of and respect for the desires of BIID individuals are the first steps in providing care and may decrease the huge burden they experience.

    Body Integrity Identity Disorder (BIID) is a rare, infrequently studied and highly secretive condition in which there is a mismatch between the mental body image and the physical body. Subjects suffering from BIID have an intense desire to amputate a major limb or severe the spinal cord in order to become paralyzed. Aim of the study is to broaden the knowledge of BIID amongst medical professionals, by describing all who deal with BIID. Somatic, psychiatric and BIID characteristic data were collected from 54 BIID individuals using a detailed questionnaire. Subsequently, data of different subtypes of BIID (i.e. wish for amputation or paralyzation) were evaluated. Finally, disruption in work, social and family life due to BIID in subjects with and without amputation were compared. Based on the subjects' reports we found that BIID has an onset in early childhood. The main rationale given for their desire for body modification is to feel complete or to feel satisfied inside. Somatic and severe psychiatric co-morbidity is unusual, but depressive symptoms and mood disorders can be present, possibly secondary to the enormous distress BIID puts upon a person. Amputation and paralyzation variant do not differ in any clinical variable. Surgery is found helpful in all subjects who underwent amputation and those subjects score significantly lower on a disability scale than BIID subjects without body modification.

  17. Gender identity disorder.

    Gender Identity Disorder (GID) is a relatively rare condition of atypical gender development in which there is a psychological perception of self as masculine or feminine which is incongruent with ones phenotype. GID replaced the term Transsexualism in DSM-IV in 1994. The demographics of GID in Ireland have not been established. Since 2000 we have received 52 referrals of individuals with confirmed GID to our endocrine service for consideration for hormonal treatment (HT). Of the 52 patients 45 have male to female (MTF) GID (mean age 38.9 years) and 7 have female to male (FTM) GID (mean age 30.7 years). The age at presentation in this group is approximately 9 years older than in international series for both MTF (39 years v 30yrs) and FTM (31 yrs v 22yrs). The karyotype where analysed has been normal for their phenotypic sex. Twenty-three of the patients had received HT prior to attending our clinic that in only one case had been prescribed by a specialist. A number of patients had obtained HT via the internet or from overseas sources without medical review. Eighteen of the patients have been or are married and 14 of the group have children. The scale of referrals confirms that GID exists in the Irish population to a significant degree. Thus an appropriate care pathway for people with the condition needs to be established. This will facilitate optimum medical management of the patient group and a coherent approach to the many difficult social issues faced individuals with this disorder.

    Full Text Available Background Emerging adulthood is a core developmental period in which individuals can develop a meaningful identity in the relational domain (with a romantic partner. The aim of the study was to examine relationships between relations with parents and identity statuses in the relational domain in emerging adults. Participants and procedure Participants were 266 (47.30% males emerging adults (M = 22.50, SD = 1.73. They completed self-report measures of relations with parents and identity. Results More than half of the participants were in the moratorium status or were not involved in a romantic relationship (35% and 29%, respectively. Relations with parents were linked to identity statuses in the relational domain. Particularly, the perception of low autonomy given by the father was related to less mature identity statuses. Conclusions This study highlighted that transition from singleness to stable partnerships seems to be challenging. Therefore, it is important to examine correlates of identity statuses in this domain.

    Full Text Available The complexity of collective existence is expressed through an awareness of its real identity, which then entails an appropriate attitude towards its own negativity. Within the hierarchically structured identity, different levels of its generality make it possible to consider them as factors of a plural reality. If negativity is raised to consciousness, then its dark side is dismantled. Thus, instead of being a factor of conflict, negativity becomes an element of complementariness and a factor in the construction of a shared identity at a higher level of generality.

    The properties of, and the processes that occur in, the nocturnal stable boundary layer are not well understood, making it difficult to represent adequately in numerical models. The nocturnal boundary layer often is characterized by a temperature inversion and, in the Southern Great Plains region, a low-level jet. To advance our understanding of the nocturnal stable boundary layer, high temporal and vertical resolution data on the temperature and wind properties are needed, along with both large-eddy simulation and cloud-resolving modeling.

    2016-01-02

    Longitudinal patterns of identity formation were analyzed in a representative cohort group of Finnish men and women born in 1959 across ages 27, 36, 42, and 50. The data were drawn from the Jyväskylä Longitudinal Study of Personality. Identity status (diffused, moratorium, foreclosed, achieved) from all four ages was available for 172 participants (54% females). Marcia's Identity Status Interview used in this research included five domains: religious beliefs, political identity, occupational career, intimate relationships, and lifestyle. The findings indicated great variability in identity status across domains at each age level, and the identity trajectories fluctuated from age 27 to 50. The developmental trend from age 27 to 50 was moderately progressive (toward achievement) for the five domains and for overall identity, with the exception of a slightly regressive trend in male religious identity. Remaining stable in the same status category across the four measurements was rare and emerged only for diffusion in the ideological domains. Women generally outnumbered men in identity achievement at earlier ages, but the gender differences diminished in most domains at age 50, except in religious identity. In women overall diffusion decreased over time, but in men it remained at about 20% at ages 42 and 50.

  18. FREE-FLOATING IDENTITIES: SOCIAL PAIN OR SOCIAL GAIN?

    Directory of Open Access Journals (Sweden)

    Tadej Praprotnik

    2014-09-01

    Full Text Available The article is focused to the problem of identity. It sketches some basic assumptions and questions the notion of identity. Identities are not stable and everlasting entities of some sort, because it is typical of the present time to be aware of the absence of any firm ground that could make universal identification possible. The truth about identities has to be sought first and foremost in its constant course of redefinition and denial, some continuous cutting of the rotten away from the good parts; it is not, as could well be expected, a goal of some kind that individuals might eventually achieve. The question of identity is problematized within the new media environment too. The potential of virtual reality lies actually in the very process of redefinition of identities itself, which is very typical for this reality. The individuals should find out that they themselves are constructed but that they can redefine again their individuality and identity in the corresponding internet environment. As far as idea of “virtual liberation” is concerned – we come across many questions and problems. The first problem concerns the fact that virtual persons are still “the same” persons. The question of creativity is connected to this because it is more and more obvious that the biggest limitation in virtual world are the people themselves. They project into virtual space all that they have learnt and realized in everyday life. In this sense the internet and popular culture connected with it are especially and above all an extension and not the alternative to the existing culture.

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

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

    2017-09-01

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

    People perceive that if their memories and moral beliefs changed, they would change. We investigated why individuals respond this way. In Study 1, participants judged that identity would change more after changes to memories and widely shared moral beliefs (e.g., about murder) versus preferences and controversial moral beliefs (e.g., about abortion). The extent to which participants judged that changes would affect their relationships predicted identity change (Study 2) and mediated the relationship between type of moral belief and perceived identity change (Study 3). We discuss the role that social relationships play in judgments of identity and highlight implications for psychology and philosophy. Copyright © 2016 Cognitive Science Society, Inc.

    In 1936, Alfred Nier produced the first precise measurement of isotope abundance ratios and his design still remains the basis of stable isotope mass spectrometry. With this gift from the physicists for routine measurement of isotope ratios, earth scientists began to explore the natural variations of isotopes. Thus began a new era in geoscience research with the hydrological cycle and marine palaeoclimatic research being the first topics to be investigated. Stable isotope measurements have been applied to many fundamental problems in geochemistry, petrology and paleoclimatology, as well as related fields in archaeology, anthropology, physical chemistry, biology and forensic sciences.

    Transracial adoptees represent a specific group of immigrants who experience unique immigration processes that bring them face-to-face with two cultural backgrounds: that of their heritage culture on one hand and that of their national culture on the other hand. However, there is a scarcity of studies focused on the way these processes unfold within adoptive families. This study was aimed at exploring how transracial adoptees cope with the construction of their ethnic identity. Administering a self-report questionnaire to 127 transracial adoptees and their mothers, for a total of 254 participants, we first investigated the association between mothers' cultural socialisation (enculturation and preparation for bias strategies) and adoptees' ethnic identity (i.e. ethnic identity exploration and ethnic identity affirmation dimensions). We then investigated whether ethnic identity affects self-esteem by testing the hypothesis that national identity moderates the relationship between ethnic identity and self-esteem. Results revealed that mothers' enculturation (but not their preparation for bias) supported adoptees' ethnic identity exploration, which in turn was positively associated with ethnic identity affirmation. Moreover, we confirmed the moderation effect: ethnic identity affirmation enhanced the level of self-esteem, but only for those adoptees who perceived a higher degree of national identity affirmation. © 2015 International Union of Psychological Science.

  5. Body talk: students' identity construction while discussing a socioscientific issue

    2012-06-01

    Vision II school science is often stated to be a democratic and inclusive form of science education. But what characterizes the subject who fits into the Vision II school science? Who is the desirable student and who is constructed as ill-fitting? This article explores discourses that structure the Vision II science classroom, and how different students construct their identities inside these discourses. In the article we consider school science as an order of discourses which restricts and enables what is possible to think and say and what subject-positions those are available and non-available. The results show that students' talk about a SSI about body and health is constituted by several discourses. We have analyzed how school science discourse, body discourse and general school discourse are structuring the discussions. But these discourses are used in different ways depending on how the students construct their identities in relation to available subject positions, which are dependent on how students at the same time are "doing" gender and social class. As an example, middle class girls show resistance against SSI-work since the practice is threatening their identity as "successful students". This article uses a sociopolitical perspective in its discussions on inclusion and exclusion in the practice of Vision II. It raises critical issues about the inherited complexity of SSI with meetings and/or collisions between discourses. Even if the empirical results from this qualitative study are situated in specific cultural contexts, they contribute with new questions to ask concerning SSI and Vision II school science.

    Ibourk, Amal

    While many studies have investigated the relationship between teachers' identity work and their developing practices, few of these identity focused studies have honed in on teacher candidates' learning to teach in an urban setting. Drawing upon narrative inquiry methodology and a "storied identity" analytic framework, I examined how the storied identities of science learning and becoming a science teacher shape teacher candidates' developing practice. In particular, I examined the stories of three interns, Becky, David, and Ashley, and I tell about their own experiences as science learners, their transitions to science teachers, and the implications this has for the identity work they did as they navigated the challenges of learning to teach in high-needs schools. Initially, each of the interns highlighted a feeling of being an outsider, and having a difficult time becoming a fully valued member of their classroom community in their storied identities of becoming a science teacher in the beginning of their internship year. While the interns named specific challenges, such as limited lab materials and different math abilities, I present how they adapted their lesson plans to address these challenges while drawing from their storied identities of science learning. My study reveals that the storied identities of becoming a science teacher informed how they framed their initial experiences teaching in an urban context. In addition, my findings reveal that the more their storied identities of science learning and becoming a science teacher overlapped, the more they leveraged their storied identity of science learning in order to implement teaching strategies that helped them make sense of the challenges that surfaced in their classroom contexts. Both Becky and Ashley leveraged their storied identities of science learning more than David did in their lesson planning and learning to teach. David's initial storied identity of becoming a science teacher revealed how he

    2009-01-01

    Full Text Available This article explores elements of masculine subjectivity and identity based on interviews with men from median and low income groups whose spouses pressed charges against them with the Family Commissioners (comisaría de familia of Bogota. Based on the poststructuralist tradition in social sciences and pro-feminist studies about masculinities, the article examines the significances and representations of the men about the occurrences of intrafamilial violence, in the context of the negotiation of homes in front of family judges. The article points out properties of the accounts related to everyday practices that represent a tactical character in the negotiation of the representation of self, and are codified expressions of cultural constructs that configure the relationships between intrafamilial violence and masculinity. It is shown how intervention processes in matters that traditionally were reserved for private consideration, have allowed to evidence the ambivalence of masculine identities to get rid of the stigma of having been reported and consolidate images that result in accordance with hegemonic patterns of representation and power.

    The existing research findings still do not provide a clear understanding of the links between adolescent school experience and their identity formation. To address this gap, we analyzed the dynamic links between adolescent school experiences and identity formation by exploring the cross-lagged associations between school engagement, school burnout and identity processing styles (information-oriented, normative and diffuse-avoidant) over a 2-year period during middle-to-late adolescence. The sample of this school-based study included 916 adolescents (51.4% females) in the 9th to 12th grades from diverse socio-economic and family backgrounds. The results from the cross-lagged analyses with three time points revealed that (a) school engagement positively predicted information-oriented identity processing over a 2-year period; (b) school burnout positively predicted the reliance on normative and diffuse-avoidant identity styles across the three measurements; (c) the effects were stable over the three time points and across different gender, grade, and socio-economic status groups. The unidirectional effects identified in our study support the general prediction that active engagement in learning at school can serve as a resource for adolescent identity formation, while school burnout, in contrast, can hinder the formation of adolescent identity. This points to the importance of taking developmental identity-related needs of adolescents into account when planning the school curriculum.

  13. Gender, identities and environment: historiographical polysemies

    2009-11-01

    Full Text Available The study of the gender identities has acquired particular relevance in the contemporary agenda and has been receiving multidisciplinary views. One of the approaches that has contributed significantly to this discussion is the historiographical perspective. Therefore, the objective of this paper is to analyze how the categories of gender have been addressed by multiple historiographical fields, especially the aspects of social history, the fields of cultural history, the post-structuralism research, and, more recently, by historians of the environment. Expliciting the limits and prospects of these studies within each historiographical paradigm, the importance of incorporating the gender perspective to the density of the theoretical debate on human and social sciences will be emphasized. Key-words: History; gender; culture; social justice; environment

    2014-04-01

    As the body of scientific knowledge in a discipline increases, there is pressure for specialization. Fields spawn subfields that then become entities in themselves that promote further specialization. The process by which scientists join specialized groups has remarkable similarities to the guild system of the middle ages. The advantages of specialization of science include efficiency, the establishment of normative standards, and the potential for greater rigor in experimental research. However, specialization also carries risks of monopoly, monotony, and isolation. The current tendency to judge scientific work by the impact factor of the journal in which it is published may have roots in overspecialization, as scientists are less able to critically evaluate work outside their field than before. Scientists in particular define themselves through group identity and adopt practices that conform to the expectations and dynamics of such groups. As part of our continuing analysis of issues confronting contemporary science, we analyze the emergence and consequences of specialization in science, with a particular emphasis on microbiology, a field highly vulnerable to balkanization along microbial phylogenetic boundaries, and suggest that specialization carries significant costs. We propose measures to mitigate the detrimental effects of scientific specialism.

  15. Hierarchy of modular graph identities

    The low energy expansion of Type II superstring amplitudes at genus one is organized in terms of modular graph functions associated with Feynman graphs of a conformal scalar field on the torus. In earlier work, surprising identities between two-loop graphs at all weights, and between higher-loop graphs of weights four and five were constructed. In the present paper, these results are generalized in two complementary directions. First, all identities at weight six and all dihedral identities at weight seven are obtained and proven. Whenever the Laurent polynomial at the cusp is available, the form of these identities confirms the pattern by which the vanishing of the Laurent polynomial governs the full modular identity. Second, the family of modular graph functions is extended to include all graphs with derivative couplings and worldsheet fermions. These extended families of modular graph functions are shown to obey a hierarchy of inhomogeneous Laplace eigenvalue equations. The eigenvalues are calculated analytically for the simplest infinite sub-families and obtained by Maple for successively more complicated sub-families. The spectrum is shown to consist solely of eigenvalues s(s−1) for positive integers s bounded by the weight, with multiplicities which exhibit rich representation-theoretic patterns.

  16. At the Intersection of Identities

    Directory of Open Access Journals (Sweden)

    2016-12-01

    Full Text Available It is assumed that part of today’s societal difficulties, uncertainties and crisis worldwide can be attributed to the competing of multiple identities, to their intersections and their overlapping nature – on the level of nations, on the level of communities and also on the level of the individual. We aim at presenting a typology of identities that come into play in the public and in the private domain of the individual. It is hypothesized that there is a strong interdependence of cultural heritage, human values and social traditions in the competition of identities. These questions, which are interrelated and interconnected with each other through a common denominator, namely “cultural-mental programming” and “reprogramming efforts,” are going to be pondered about in the presentation. In the context of globalization the relevance of this topic is reinforced by the need to adapt to changes within the ever-intensifying shift from intercultural to multicultural environment in communities, in business and in work places. Attempts will be made to articulate some projections with respect to future trends that are to be expected: the way to go from competing identities to establishing a competitive identity (Simon Anholt. The contribution does not offer ready solutions but rather serves as fuel for further discussions.

  17. Leisure Time and Social Identity

    2010-01-01

    Full Text Available How could patterns of leisure represent social identity? Whether they are sub-ordinate to the class identity or in the contemporary context of consumption and the post-modern cultural transformations, they could represent some other different social identities based on the patterns of consumption? Considering “leisure time” as a part of “style of life”, the present study attempts to explore social identity. There are two parts in methodology; first the qualitative one, carried through deep interview technique; and the other, surveying through questionnaire. Results distinguish the determining role “social class”, and the combination of “gender” and social class play in modeling distinctions in leisure patterns. In other words, leisure –as the arena for individual choice- is restricted to the social class and gender –as the structural and contextual variables. The strong correlation identity has with the social class and gender denies the post-modern interpretations which emphasis on consumption as the cause of social differentiations.

    Full Text Available The purpose of this study was to investigate the factors influencing the identity deaf adolescents. The study involved 67 deaf adolescents (38 boys and 29 girls aged 16 to 19 students of secondary school. Ninety-three hearing children constituted a comparison group. The structure of identity was explored on the basis of identification references given by the subjects who were to reply in writing, 20 times running, to the question: „Who Am I?” the test, adapted from M. H. Kuhn and T. S. McPartland by Martines and Silvestre (1995 given in written and signed mode.Results showed that the hearing status as well as mode of communication influence the description of personal identity. It was found that deaf adoles­cents used more descriptions especially in the fol­lowing categories: Civil Status, Body and Physical Appearance, Tastes and Activities, Friendship and Relationships, Personal and Social Situation, Negative Personal Traits, and Neutral Personality Traits. Although this study could demonstrate im­pact independent variables on identity, the data raise the need for further, preferably longitudinal, research. This complex phenomenon has to be examined more closely.Combined self-descriptive processes lead to the development of an organized, learned and dynamic identity, and subjective description of an individ­ual has strong emotional consequences for the in­dividual in question.

  19. Identity change and informed consent.

    Science.gov (United States)

    Witt, Karsten

    2017-06-01

    In this paper, I focus on a kind of medical intervention that is at the same time fascinating and disturbing: identity-changing interventions. My guiding question is how such interventions can be ethically justified within the bounds of contemporary bioethical mainstream that places great weight on the patient's informed consent. The answer that is standardly given today is that patients should be informed about the identity effects, thus suggesting that changes in identity can be treated like 'normal' side effects. In the paper, I argue that this approach is seriously lacking because it misses important complexities going along with decisions involving identity changes and consequently runs into mistakes. As a remedy I propose a new approach, the 'perspective-sensitive account', which avoids these mistakes and thus provides the conceptual resources to systematically reflect on and give a valid consent to identity-changing interventions.

  20. Role of stable isotope mass spectroscopy in hydrological sciences

    International Nuclear Information System (INIS)

    Keesari, Tirumalesh

    2017-01-01

    Isotope Ratio Mass Spectrometry (IRMS) is a specialized technique used to provide information about a given sample about its geographic, chemical, physical and biological origin. The ability to determine the source of water molecule stems from the relative isotopic abundances of its constituent elements, viz., hydrogen and oxygen or sometimes through its dissolved elements such as carbon, nitrogen and sulphur etc. Since the isotope ratios of carbon, hydrogen, oxygen, sulfur, and nitrogen can become locally enriched or depleted through a variety of kinetic and thermodynamic factors, measurement of the isotope ratios can be used to unravel the processes and differentiate water samples which otherwise exhibit similar chemical signatures. For brevity, this article focuses mainly on measurement of water isotopes, common notation for expressing isotope data and standards, theory of isotope hydrology, field applications and advances

    2017-10-01

    Public debates about socio-scientific issues (e.g. climate change or violent video games) are often accompanied by attacks on the reputation of the involved scientists. Drawing on the social identity approach, we report a minimal group experiment investigating the conditions under which scientists are perceived as non-prototypical, non-reputable, and incompetent. Results show that in-group affirming and threatening scientific findings (compared to a control condition) both alter laypersons' evaluations of the study: in-group affirming findings lead to more positive and in-group threatening findings to more negative evaluations. However, only in-group threatening findings alter laypersons' perceptions of the scientists who published the study: scientists were perceived as less prototypical, less reputable, and less competent when their research results imply a threat to participants' social identity compared to a non-threat condition. Our findings add to the literature on science reception research and have implications for understanding the public engagement with science.

    2017-11-01

    Full Text Available In today's globalized world, it is important to find a relationship to our own culture as well as to the other cultures which we encounter due to migration. This goal should be met in multicultural education. As a result of the so-called migration crisis, effectiveness of multicultural education was discussed on social networks and in media. At the same time, national interests and security began to appear in the programmes of political parties. It seems that, due to the fear of refugees, national identity started becoming more important. The situation is reflected in the research presented below. It aimed to determine whether there was a link between the sense of national identity and attitudes to foreigners. The investigation was carried out in 2015 on a sample of 245 respondents. The results showed that the growing sense of national identity deepened the negative attitude to foreigners. It is necessary to work with this fact in multicultural education at schools.

    2006-02-01

    This paper reviews the ICAO security architecture for biometric passports. An attack enabling RFID identity theft for a later misuse is presented. Specific countermeasures against this attack are described. Furthermore, it is shown that robust high capacity digital watermarking for the embedding and retrieving of binary digital signature data can be applied as an effective mean against RFID identity theft. This approach requires only minimal modifications of the passport manufacturing process and is an enhancement of already proposed solutions. The approach may also be applied in combination with a RFID as a backup solution (damaged RFID chip) to verify with asymmetric cryptographic techniques the authenticity and the integrity of the passport data.

    Identity verification devices based on the interrogation of six different human biometric features or actions now exist and in general have been in development for about ten years. The capability of these devices to meet the cost and operational requirements of speed, accuracy, ease of use and reliability has generally increased although the verifier industry is still immature. Sandia Laboratories makes a continuing effort to stay abreast of identity verifier developments and to assess the capabilities and improvements of each device. Operating environment and procedures more typical of field use can often reveal performance results substantially different from laboratory tests.

    2011-07-19

    Pagerank, a network-based diffusion algorithm, has emerged as the leading method to rank web content, ecological species and even scientists. Despite its wide use, it remains unknown how the structure of the network on which it operates affects its performance. Here we show that for random networks the ranking provided by pagerank is sensitive to perturbations in the network topology, making it unreliable for incomplete or noisy systems. In contrast, in scale-free networks we predict analytically the emergence of super-stable nodes whose ranking is exceptionally stable to perturbations. We calculate the dependence of the number of super-stable nodes on network characteristics and demonstrate their presence in real networks, in agreement with the analytical predictions. These results not only deepen our understanding of the interplay between network topology and dynamical processes but also have implications in all areas where ranking has a role, from science to marketing.

  1. Toward Practical Secure Stable Matching

    Directory of Open Access Journals (Sweden)

    2017-01-01

    Full Text Available The Stable Matching (SM algorithm has been deployed in many real-world scenarios including the National Residency Matching Program (NRMP and financial applications such as matching of suppliers and consumers in capital markets. Since these applications typically involve highly sensitive information such as the underlying preference lists, their current implementations rely on trusted third parties. This paper introduces the first provably secure and scalable implementation of SM based on Yao’s garbled circuit protocol and Oblivious RAM (ORAM. Our scheme can securely compute a stable match for 8k pairs four orders of magnitude faster than the previously best known method. We achieve this by introducing a compact and efficient sub-linear size circuit. We even further decrease the computation cost by three orders of magnitude by proposing a novel technique to avoid unnecessary iterations in the SM algorithm. We evaluate our implementation for several problem sizes and plan to publish it as open-source.

    1992-11-01

    For the whole set of dilogarithm identities found recently using the thermodynamic Bethe-Ansatz for the ADET series of purely elastic scattering theories we give partition identities which involve characters of those conformal field theories which correspond to the UV-limits of the scattering theories. These partition identities in turn allow to derive the dilogarithm identities using modular invariance and a saddle point approximation. We conjecture on possible generalizations of this correspondance, namely, a lift from dilogarithm to partition identities. (orig.)

It is possible sustain that is a legacy of Modernity that the personis the main character of her own life and configure it by means of autonomous decisions. It is true thatshe must decide, although she has to do so from deep convictions if she does not want to be influencedby a culture that —in Charles Taylor’s perspective— has trivialized the ideal of authenticity and hasexalted a freedom that increases individualism. This essay is focused on the actions full of significance and the adherence to true goods that shape the identity and its narrative. The basics are in the anthropology and ethics of the philosopher just mentioned.

  10. Identity disturbance in distant patients.

    Science.gov (United States)

    Hoffman, Irwin

    2013-04-01

    Chronically distant, emotionally isolated patients often present with identity disturbance. Identity, it is argued, develops as a thematic pattern of narcissism, shaped by the nature of the mother's early libidinal influences on the child's sense of self. Identity provides a form of self-definition that addresses the question, Who am I? In the treatment of these patients, resistances to narcissistic vulnerabilities (narcissistic resistances) provide an illusory sense of security and induce the analyst to avoid attention to a central pathological problem: primitive and frightening needs for, and unconscious fantasies of, dependence on, and functionality for, another. Patients' avoidance of material and therapeutic interactions that deal with their dependencies are aspects of a tacit contract with the analyst to foreclose examination of their considerable problems with inner stability. Among these problems are anxieties regarding intrusion and loss of separateness. As analysis proceeds, elements of such a patient's identity become clarified and are used to understand and organize the material for both analyst and patient. This can allow the patient to articulate a more embodied and vital experience of individuality. A case is presented to illustrate the analysis of a patient using this approach.

  15. [Identity and narration: autobiographical quests].

    This paper aims to tackle the subtle relation between autobiographical narratives and identity construction, from a non essentialist conception of identity. In a perspective that articulates philosophy of language, psychoanalysis, semiotics and literary critique, we posit the concept of biographical space as an analytical instrument to make a critical update of the reconfiguration of identities and subjectivities in contemporary culture, marked by the predominance of the biographical, the private and a kind of "public intimacy". This look is more symptomatic than descriptive: it intends to account for the rise of auto/biographical narratives and life-stories, from canonic genres to their multiple derivations in the media, social networks and the most diverse artistic practices, a phenomenon that seems to reaffirm the notion of narrative identities by Ricoeur. Our analysis here, from an ethic, aesthetic and political point of view, will focus on two visual arts experiences that have recently taken place for the first time in Buenos Aires: Christian Boltanski's and Tracey Emin's, solo exhibitions, each of them with a different biographical approach.
