    2015-04-29

    Grounded theory is a popular research approach in health care and the social sciences. This article provides a description of grounded theory methodology and its key components, using examples from published studies to demonstrate practical application. It aims to demystify grounded theory for novice nurse researchers, by explaining what it is, when to use it, why they would want to use it and how to use it. It should enable nurse researchers to decide if grounded theory is an appropriate approach for their research, and to determine the quality of any grounded theory research they read.

    In response to the 2004 tsunami disaster in the Indian Ocean, the U.S. Navy deployed teams aboard the USNS Mercy to provide aid during Operation Unified Assistance (OUA). To date, few research studies have examined how Navy nurses prepared for and clinically performed during this relief operation. The current article describes the challenges faced by Navy nurses throughout OUA. A purposive convenience sample was recruited; 11 participated. Data were collected from interviews, observations, field notes, memos, and a demographic tool. Information was categorized, coded, compared to incoming data, then analyzed using Strauss and Corbin's open coding, axial coding, and selective coding methods. A theoretical model was developed to illustrate how participants experienced the mission. Key lessons learned were that most were unprepared for providing pediatric care, and saying "No" in delivering care. Recommendations include: deployment of advanced-practice nurses (specialists in pediatrics and well-mental health) and predeployment training on moral distress.

  8. [Introduction to grounded theory].

    PubMed

    Wang, Shou-Yu; Windsor, Carol; Yates, Patsy

    2012-02-01

    Grounded theory, first developed by Glaser and Strauss in the 1960s, was introduced into nursing education as a distinct research methodology in the 1970s. The theory is grounded in a critique of the dominant contemporary approach to social inquiry, which imposed "enduring" theoretical propositions onto study data. Rather than starting from a set theoretical framework, grounded theory relies on researchers distinguishing meaningful constructs from generated data and then identifying an appropriate theory. Grounded theory is thus particularly useful in investigating complex issues and behaviours not previously addressed and concepts and relationships in particular populations or places that are still undeveloped or weakly connected. Grounded theory data analysis processes include open, axial and selective coding levels. The purpose of this article was to explore the grounded theory research process and provide an initial understanding of this methodology.

  9. Application of grounded theory to content definition: a case study.

    PubMed

    Audiss, D; Roth, T

    1999-02-01

    Successful implementation of a clinical information system requires clinician involvement throughout the process of content definition and system development to ensure acceptance of the automated care process. In these times of downsizing, however, clinicians are not always able to participate fully in the dontent definition phase of system development and often become frustrated with their inability to obtain the patient information they need from the system. The qualitative research principles of grounded theory afford clinicians the opportunity to participate in content definition for information systems. This article presents a case study of the application of grounded theory to develop systematically the content definition for a clinical information system in preparation for implementation on four medical-surgical units.

  10. Understanding Jordanian Psychiatric Nurses' Smoking Behaviors: A Grounded Theory Study

    Aldiabat, Khaldoun M.; Clinton, Michael

    2013-01-01

    Purpose. Smoking is prevalent in psychiatric facilities among staff and patients. However, there have been few studies of how contextual factors in specific cultures influence rates of smoking and the health promotion role of psychiatric nurses. This paper reports the findings of a classical grounded theory study conducted to understand how contextual factors in the workplace influences the smoking behaviors of Jordanian psychiatric nurses (JPNs). Method. Semi-structured individual interviews were conducted with a sample of eight male JPNs smokers at a psychiatric facility in Amman, Jordan. Findings. Constant comparative analysis identified becoming a heavy smoker as a psychosocial process characterized by four sub-categories: normalization of smoking; living in ambiguity; experiencing workplace conflict; and, facing up to workplace stressors. Conclusion. Specific contextual workplace factors require targeted smoking cessation interventions if JPNs are to receive the help they need to reduce health risks associated with heavy smoking.

  11. De-tabooing dying control - a grounded theory study

    PubMed Central

    2013-01-01

    Background Dying is inescapable yet remains a neglected issue in modern health care. The research question in this study was “what is going on in the field of dying today?” What emerged was to eventually present a grounded theory of control of dying focusing specifically on how people react in relation to issues about euthanasia and physician-assisted suicide (PAS). Methods Classic grounded theory was used to analyze interviews with 55 laypersons and health care professionals in North America and Europe, surveys on attitudes to PAS among physicians and the Swedish general public, and scientific literature, North American discussion forum websites, and news sites. Results Open awareness of the nature and timing of a patient’s death became common in health care during the 1960s in the Western world. Open dying awareness contexts can be seen as the start of a weakening of a taboo towards controlled dying called de-tabooing. The growth of the hospice movement and palliative care, but also the legalization of euthanasia and PAS in the Benelux countries, and PAS in Montana, Oregon and Washington further represents de-tabooing dying control. An attitude positioning between the taboo of dying control and a growing taboo against questioning patient autonomy and self-determination called de-paternalizing is another aspect of de-tabooing. When confronted with a taboo, people first react emotionally based on “gut feelings” - emotional positioning. This is followed by reasoning and label wrestling using euphemisms and dysphemisms - reflective positioning. Rarely is de-tabooing unconditional but enabled by stipulated positioning as in soft laws (palliative care guidelines) and hard laws (euthanasia/PAS legislation). From a global perspective three shapes of dying control emerge. First, suboptimal palliative care in closed awareness contexts seen in Asian, Islamic and Latin cultures, called closed dying. Second, palliative care and sedation therapy, but not euthanasia

    The objective of this study was to explore the process of transition into fatherhood for Thai men from childbirth to the postpartum period. Forty-one first-time Thai fathers were voluntarily recruited from two hospitals in Chiang Mai, Thailand, from December 2012 to June 2013. In-depth interviews were used to collect the data, which were analyzed based on grounded theory methodology. The basic social process that emerged as the core category was termed: "the journey into fatherhood." This process was divided into three phases: labor, delivery, and family beginning. Within this process, there were various situations, challenges, and pressures, which caused many changes of mood and feelings for the first-time fathers. Throughout this process, they applied various strategies to manage their concerns and needs, in order to develop into masterly fathers. Identifying the process of the journey into fatherhood provides nurses and midwives insight into the new fathers' experiences, which will enable them to be more sensitive, respectful, and effective caregivers.

  14. Academic learning for specialist nurses: a grounded theory study.

    PubMed

    Millberg, Lena German; Berg, Linda; Brämberg, Elisabeth Björk; Nordström, Gun; Ohlén, Joakim

    2014-11-01

    The aim was to explore the major concerns of specialist nurses pertaining to academic learning during their education and initial professional career. Specialist nursing education changed in tandem with the European educational reform in 2007. At the same time, greater demands were made on the healthcare services to provide evidence-based and safe patient-care. These changes have influenced specialist nursing programmes and consequently the profession. Grounded Theory guided the study. Data were collected by means of a questionnaire with open-ended questions distributed at the end of specialist nursing programmes in 2009 and 2010. Five universities were included. Further, individual, pair and group interviews were used to collect data from 12 specialist nurses, 5-14 months after graduation. A major concern for specialist nurses was that academic learning should be "meaningful" for their professional future. The specialist nurses' "meaningful academic learning process" was characterised by an ambivalence of partly believing in and partly being hesitant about the significance of academic learning and partly receiving but also lacking support. Specialist nurses were influenced by factors in two areas: curriculum and healthcare context. They felt that the outcome of contribution to professional confidence was critical in making academic learning meaningful.

  15. Adolescents coping with mood disorder: a grounded theory study.

    PubMed

    Meadus, R J

    2007-04-01

    A grounded theory methodology was used to explore the phenomenon of coping as experienced by adolescents with a mood disorder. Mood disorders among children and adolescents are more persistent than previously thought and have numerous negative associated features, including further episodes of depression, impaired social, academic and vocational relationships, use of alcohol and other drugs, and an increased risk of suicide. Current literature offered little awareness of how adolescents cope with a mood disorder, as well as their perspective of how such an illness impacts their lives. A substantive theory regarding the process of coping for adolescents with a mood disorder was generated from the data collected from one male and eight female adolescents. Using grounded theory coding procedures, a four-phase coping theory identified by the categories feeling different, cutting off connections, facing the challenge/reconnecting, and learning from the experience was developed. The core category identified in this research was An Unplanned Journey: Coping Through Connections. Implications identified for nursing practice, research and education included greater attention on the prevention of adolescent mood disorder, and the education of adolescents about the development and enhancement of healthy coping skills.

  16. Minority nursing student success: A grounded theory case study

    NASA Astrophysics Data System (ADS)

    Mister, Brenda J.

    There has been a dramatic increase in the nation's racial and ethnic minority populations over recent years. This increase is placing a higher demand on the health care industry to provide culturally competent care to these diverse populations. This challenge is met with yet another problem as the nation faces a critical shortage of nurses, particularly minority nurses. This shortage is only expected to worsen over the next several years. As schools of nursing across the country are being asked to increase the number of nursing program graduates, specifically minorities, they are confronted with a double edged sword as retention rates are decreasing, and attrition rates are increasing. This is particularly troublesome when many racial and ethnic minority nursing students do not graduate. This qualitative study was implemented to assess and understand the perceived educational experiences of racial and ethnic minority nursing students enrolled in a rural community college nursing program on the Eastern Shore of Maryland. Eight voluntary nursing students who identified themselves as either a racial or ethnic minority participated in the study. Data were collected by: individual audio-taped interview sessions; audio-taped focus group sessions; and documentation of field notes. Participants also provided demographic information and were asked to provide a brief written response to a scenario regarding increasing the recruitment and retention rates of minority nursing students. All data were analyzed utilizing the constant comparative method. Results of the study revealed six different themes: personal support systems and peer relationships; college services and academic resources; faculty support; cultural understanding versus cultural insensitivity; personal attributes of self-efficacy/advice for future nursing students; and suggestions for college and nursing program improvement. After the major themes were examined one central theme, a grounded theory, was born. The

    Compassionate practice is expected of Registered Nurses (RNs) around the world while at the same time remaining a contested concept. Nevertheless, student nurses are expected to enact compassionate practice in order to become RNs. In order for this to happen they require professional socialisation within environments where compassion can flourish. However, there is concern that student nurse socialisation is not enabling compassion to flourish and be maintained upon professional qualification. In order to investigate this further, a glaserian Grounded Theory study was undertaken using in-depth, digitally recorded interviews with student nurses (n=19) at a university in the north of England during 2009 and 2010. Interviews were also undertaken with their nurse teachers (n=5) and data from National Health Service (NHS) patients (n=72,000) and staff (n=290,000) surveys were used to build a contextual picture of the student experience. Within the selected findings presented, analysis of the data indicates that students aspire to the professional ideal of compassionate practice although they have concerns about how compassionate practice might fit within the RN role because of constraints on RN practice. Students feel vulnerable to dissonance between professional ideals and practice reality. They experience uncertainty about their future role and about opportunities to engage in compassionate practice. Students manage their vulnerability and uncertainty by balancing between an intention to uphold professional ideals and challenge constraints, and a realisation they might need to adapt their ideals and conform to constraints. This study demonstrates that socialisation in compassionate practice is compromised by dissonance between professional idealism and practice realism. Realignment between the reality of practice and professional ideals, and fostering student resilience, are required if students are to be successfully socialised in compassionate practice and enabled

  1. A taxonomy of dignity: a grounded theory study

    2009-01-01

    Background This paper has its origins in Jonathan Mann's insight that the experience of dignity may explain the reciprocal relationships between health and human rights. It follows his call for a taxonomy of dignity: "a coherent vocabulary and framework to characterize dignity." Methods Grounded theory procedures were use to analyze literature pertaining to dignity and to conduct and analyze 64 semi-structured interviews with persons marginalized by their health or social status, individuals who provide health or social services to these populations, and people working in the field of health and human rights. Results The taxonomy presented identifies two main forms of dignity–human dignity and social dignity–and describes several elements of these forms, including the social processes that violate or promote them, the conditions under which such violations and promotions occur, the objects of violation and promotion, and the consequences of dignity violation. Together, these forms and elements point to a theory of dignity as a quality of individuals and collectives that is constituted through interaction and interpretation and structured by conditions pertaining to actors, relationships, settings, and the broader social order. Conclusion The taxonomy has several implications for work in health and human rights. It suggests a map to possible points of intervention and provides a language in which to talk about dignity.

  2. Stigma in abortion care: application to a grounded theory study.

    PubMed

    Lipp, Allyson

    2011-02-01

    A recent research study found that being more directly involved in medical abortion places greater demands on the nurses. The demands required by nurses working in abortion care may be increased by the stigma attached to such an antisocial action. This paper presents an application of stigma theory, as espoused by Goffman, based on a qualitative research study on abortion. It is argued that women attending for abortion are stigmatised and nurses, although 'wise', have an affiliate stigma through their close association with the procedure. It is proposed that the situation can be ameliorated by addressing stigma at policy, local and personal levels. Examples from other areas of practice are outlined for possible application to practice.

    Aim A longer duration of untreated psychosis (DUP) is associated with greater morbidity in the early course of schizophrenia. This formative, hypothesis-generating study explored the effects of stigma, as perceived by family members, on DUP. Methods Qualitative interviews were conducted with 12 African American family members directly involved in treatment initiation for a relative with first-episode psychosis. Data analysis relied on a grounded theory approach. A testable model informed by constructs of Link's modified labelling theory was developed. Results Four main themes were identified, including: (i) society's beliefs about mental illnesses; (ii) families' beliefs about mental illnesses; (iii) fear of the label of a mental illness; and (iv) a raised threshold for the initiation of treatment. A grounded theory model was developed as a schematic representation of the themes and subthemes uncovered in the family members' narratives. Conclusions The findings suggest that due to fear of the official label of a mental illness, certain coping mechanisms may be adopted by families, which may result in a raised threshold for treatment initiation, and ultimately treatment delay. If the relationships within the grounded theory model are confirmed by further qualitative and quantitative research, public educational programs could be developed with the aim of reducing this threshold, ultimately decreasing DUP.

    2011-05-01

    In this present grounded theory study, 16 experienced psychologists, who practiced from varied theoretical orientations and came from diverse religious/spiritual/nonreligious backgrounds, explored their personal religious/spiritual/nonreligious identity development journeys, their experiences with clients' religious/spiritual content in psychotherapy sessions, and how their identity may have influenced the way they interacted with religious/spiritual material during sessions. Results revealed that psychologists' spiritual/religious/nonreligious identity is conflicted and complex and that their academic and clinical training did not provide sufficient opportunity to examine how this may affect their therapeutic work. A tentative grounded theory emerged suggesting that psychologists both identified with and were activated by clients' spiritual/religious conflicts and their internal experiences about the spiritual/religious content, both of which presented significant challenges to therapeutic work.

    This grounded theory study aimed to understand how Thai adolescents living with HIV pursued meaning and purpose in life. Data were gathered from 11 adolescents in southern Thailand who were between ages 18 and 20 years, and who had lived with HIV for 2 or more years. Purposive and theoretical sampling techniques were used to recruit the participants. Data were collected through in-depth interviews, participant observations, and field notes. Strauss and Corbin's (1998) grounded theory method guided data analysis. The core category of "pursuing meaning and purpose in life among Thai adolescents living with HIV" emerged out of a recursive process of uncertainty, inferiority, self-realization, and growth that comprised three categories: (a) condition: realizing self-value, (b) strategy: being connected to prolonging life, and (c) consequence: achieving peace and calm. The findings enhance knowledge that would benefit nurses helping adolescents living with HIV find meaning and purpose in life.

    This article aims to illuminate the role of narrativity in Grounded Theory Methodology and to explore an approach within Grounded Theory Methodology that is sensitized towards aspects of narrativity. The suggested approach takes into account narrativity as an aspect of the underlying data. It reflects how narrativity could be conceptually integrated and systematically used for shaping the way in which coding, category development and the presentation of results in a Grounded Theory Methodology study proceed.

    2015-01-01

    Objective: to understand the meanings given by women and men with sickle cell disease on the illness experience. Method: analytical study with a qualitative approach, conducted with 17 adults with sickle cell disease using the Theory Based on Data, or Grounded Theory, as theoretical-methodological referential. Data were collected between the years of 2012 and 2013, in an individual in-depth interview. All the interviews were recorded and analyzed according to the Grounded Theory comparative analysis technique. Results: data show four categories which group the experience of illness, the feelings experienced and the path to living with sickle cell disease. Conclusions: it was possible to understand that the experience was built by a process in which these people redefined the meaning of their lives, applying new directions to life and to care regarding the experience of the illness. In the context of chronic disease, the nurse's care is also seen in this study as a foundation, providing attention, directions, and guidance through the required confrontations. Understanding the experience lived by these people, it is possible to enlarge the dimensions and the essence of nursing care required throughout life. PMID:26626003

    2013-01-01

    Objectives Virtual patients (VPs) are online representations of clinical cases used in medical education. Widely adopted, they are well placed to teach clinical reasoning skills. International technology standards mean VPs can be created, shared and repurposed between institutions. A systematic review has highlighted the lack of evidence to support which of the numerous VP designs may be effective, and why. We set out to research the influence of VP design on medical undergraduates. Methods This is a grounded theory study into the influence of VP design on undergraduate medical students. Following a review of the literature and publicly available VP cases, we identified important design properties. We integrated them into two substantial VPs produced for this research. Using purposeful iterative sampling, 46 medical undergraduates were recruited to participate in six focus groups. Participants completed both VPs, an evaluation and a 1-hour focus group discussion. These were digitally recorded, transcribed and analysed using grounded theory, supported by computer-assisted analysis. Following open, axial and selective coding, we produced a theoretical model describing how students learn from VPs. Results We identified a central core phenomenon designated ‘learning from the VP’. This had four categories: VP Construction; External Preconditions; Student–VP Interaction, and Consequences. From these, we constructed a three-layer model describing the interactions of students with VPs. The inner layer consists of the student's cognitive and behavioural preconditions prior to sitting a case. The middle layer considers the VP as an ‘encoded object’, an e-learning artefact and as a ‘constructed activity’, with associated pedagogic and organisational elements. The outer layer describes cognitive and behavioural change. Conclusions This is the first grounded theory study to explore VP design. This original research has produced a model which enhances understanding

  10. A grounded theory study on the role of differentiated instruction in effective middle school science teaching

    NASA Astrophysics Data System (ADS)

    Jones, Brian Kirby

    The purpose of this grounded theory study was to develop a model explaining the role of differentiated instruction (DI) in effective middle school science teaching. The study examined the best teaching practices and differentiated elements from eight general education middle school science teachers, all scoring at the highest level of a teaching effectiveness measure on their evaluations, through a collection of observational, interview, survey, and teaching artifact data. The data were analyzed through the methodology of a systematic grounded theory qualitative approach using open, axial, and selective coding to develop a model describing how and to what degree effective middle school science teachers differentiated their best teaching practices. The model that emerged from the data shows instruction as a four-phase process and highlights the major elements of best practices and DI represented at each phase. The model also depicts how teachers narrowed the scope of their differentiating strategies as instruction progressed. The participants incorporated DI into their pedagogies, though in different degrees at each phase, and primarily by using variety to present concepts with multiple types of instruction followed by a series of sense-making activities related to several learning modalities. Teachers scaffolded students carefully, using informal and formal assessment data to inform future instructional decisions and especially their plans to reteach or extend on a concept. The model is intended to provide insight into the value of DI for middle school science teaching.

  12. Sifting, sorting and saturating data in a grounded theory study of information use by practice nurses: a worked example.

    PubMed

    Hoare, Karen J; Mills, Jane; Francis, Karen

    2012-12-01

    The terminology used to analyse data in a grounded theory study can be confusing. Different grounded theorists use a variety of terms which all have similar meanings. In the following study, we use terms adopted by Charmaz including: initial, focused and axial coding. Initial codes are used to analyse data with an emphasis on identifying gerunds, a verb acting as a noun. If initial codes are relevant to the developing theory, they are grouped with similar codes into categories. Categories become saturated when there are no new codes identified in the data. Axial codes are used to link categories together into a grounded theory process. Memo writing accompanies this data sifting and sorting. The following article explains how one initial code became a category providing a worked example of the grounded theory method of constant comparative analysis. The interplay between coding and categorization is facilitated by the constant comparative method.

    Thomson, Oliver P; Petty, Nicola J; Moore, Ann P

    2014-02-01

    There is limited understanding of how osteopaths make decisions in relation to clinical practice. The aim of this research was to construct an explanatory theory of the clinical decision-making and therapeutic approaches of experienced osteopaths in the UK. Twelve UK registered osteopaths participated in this constructivist grounded theory qualitative study. Purposive and theoretical sampling was used to select participants. Data was collected using semi-structured interviews which were audio-recorded and transcribed. As the study approached theoretical sufficiency, participants were observed and video-recorded during a patient appointment, which was followed by a video-prompted interview. Constant comparative analysis was used to analyse and code data. Data analysis resulted in the construction of three qualitatively different therapeutic approaches which characterised participants and their clinical practice, termed; Treater, Communicator and Educator. Participants' therapeutic approach influenced their approach to clinical decision-making, the level of patient involvement, their interaction with patients, and therapeutic goals. Participants' overall conception of practice lay on a continuum ranging from technical rationality to professional artistry, and contributed to their therapeutic approach. A range of factors were identified which influenced participants' conception of practice. The findings indicate that there is variation in osteopaths' therapeutic approaches to practice and clinical decision-making, which are influenced by their overall conception of practice. This study provides the first explanatory theory of the clinical decision-making and therapeutic approaches of osteopaths.

  15. How People Reason: A Grounded Theory Study of Scientific Reasoning about Global Climate Change

    NASA Astrophysics Data System (ADS)

    Liu, Shiyu

    Scientific reasoning is crucial in both scientific inquiry and everyday life. While the majority of researchers have studied "how people reason" by focusing on their cognitive processes, factors related to the underpinnings of scientific reasoning are still under-researched. The present study aimed to develop a grounded theory that captures not only the cognitive processes during reasoning but also their underpinnings. In particular, the grounded theory and phenomenographic methodologies were integrated to explore how undergraduate students reason about competing theories and evidence on global climate change. Twenty-six undergraduate students were recruited through theoretical sampling. Constant comparative analysis of responses from interviews and written assessments revealed that participants were mostly drawn to the surface features when reasoning about evidence. While prior knowledge might not directly contribute to participants' performance on evidence evaluation, it affected their level of engagement when reading and evaluating competing arguments on climate issues. More importantly, even though all participants acknowledged the relative correctness of multiple perspectives, they predominantly favored arguments that supported their own beliefs with weak scientific reasoning about the opposing arguments. Additionally, factors such as personal interests, religious beliefs, and reading capacity were also found to have bearings on the way participants evaluated evidence and arguments. In all, this work contributes to the current endeavors in exploring the nature of scientific reasoning. Taking a holistic perspective, it provides an in-depth discussion of factors that may affect or relate to scientific reasoning processes. Furthermore, in comparison with traditional methods used in the literature, the methodological approach employed in this work brought an innovative insight into the investigation of scientific reasoning. Last but not least, this research may

    2012-03-01

    In the course of their studies, nursing students must learn many skills and acquire the knowledge required for their future profession. This study investigates how Iranian nursing students manage their time according to the circumstances and obstacles of their academic field. Research was conducted using the grounded theory method. Twenty-one nursing students were purposefully chosen as participants. Data was collected through semi-structured interviews and analyzed using the method suggested by Corbin and Strauss. One of the three processes that the nursing students used was "unidirectional time management." This pattern consists of accepting the nursing field, overcoming uncertainty, assessing conditions, feeling stress, and trying to reduce stress and create satisfaction. It was found that students allotted most of their time to academic tasks in an attempt to overcome their stress. The findings of this study indicate the need for these students to have time for the extra-curricular activities and responsibilities that are appropriate to their age.

    2015-01-01

    After colorectal cancer (CRC) treatment, people reorganize life in ways that are consistent with their understanding of the illness and their expectations for recovery. Incapacities and abilities that have been lost can initiate a need to reorient the self. To the best of our knowledge, no studies have explicitly focused on the concept of self-reorientation after CRC treatment. The aim of the present study was therefore to explore self-reorientation in the early recovery phase after CRC surgery. Grounded theory analysis was undertaken, using the method presented by Charmaz. The present results explained self-reorientation as the individual attempting to achieve congruence in self-perception. A congruent self-perception meant bringing together the perceived self and the self that was mirrored in the near environs. The results showed that societal beliefs and personal explanations are essential elements of self-reorientation, and that it is therefore important to make them visible.

    2016-01-01

    Background To establish integrated healthcare pathways for patients with neurodevelopmental disorders (ND) such as autism spectrum disorder and attention-deficit hyperactivity disorder is challenging. This study sets out to investigate the main concerns for healthcare professionals when integrating ND care pathways and how they resolve these concerns. Methods Using classic grounded theory (Glaser), we analysed efforts to improve and integrate an ND care pathway for children and youth in a Swedish region over a period of 6 years. Data from 42 individual interviews with a range of ND professionals, nine group interviews with healthcare teams, participant observation, a 2-day dialogue conference, focus group meetings, regional media coverage, and reports from other Swedish regional ND projects were analysed. Results The main concern for participants was to deal with overwhelming ND complexity by unpacking control, which is control over strategies to define patients’ status and needs. Unpacking control is key to the professionals’ strivings to expand constructive life space for patients, to squeeze health care to reach available care goals, to promote professional ideologies, and to uphold workplace integrity. Control-seeking behaviour in relation to ND unpacking is ubiquitous and complicates integration of ND care pathways. Conclusions The Unpacking control theory expands central aspects of professions theory and may help to improve ND care development. PMID:27609793

    2009-01-01

    The purpose of this grounded theory study was to generate a theory of the interprofessional collaborative learning process of occupational therapy (OT) students who were engaged in a collaborative learning experience with students from other allied health disciplines. Data consisted of semi-structured interviews with nine OT students from four different interprofessional collaborative learning experiences at three universities. The emergent theory explained OT students' need to build a culture of mutual respect among disciplines in order to facilitate interprofessional collaborative learning. Occupational therapy students went through a progression of learned skills that included learning how to represent the profession of OT, hold their weight within a team situation, solve problems collaboratively, work as a team, and ultimately, to work in an actual team in practice. This learning process occurred simultaneously as students also learned course content. The students had to contend with barriers and facilitators that influenced their participation and the success of their collaboration. Understanding the interprofessional learning process of OT students will help allied health faculty to design more effective, inclusive interprofessional courses.

  1. A study of Iranian immigrants’ experiences of accessing Canadian health care services: a grounded theory

    PubMed Central

    2012-01-01

    Background Immigration is not a new phenomenon but, rather, has deep roots in human history. Documents from every era detail individuals who left their homelands and struggled to reestablish their lives in other countries. The aim of this study was to explore and understand the experience of Iranian immigrants who accessed Canadian health care services. Research with immigrants is useful for learning about strategies that newcomers develop to access health care services. Methods The research question guiding this study was, “What are the processes by which Iranian immigrants learn to access health care services in Canada?” To answer the question, a constructivist grounded theory approach was applied. Initially, unstructured interviews were conducted with 17 participants (11 women and six men) who were adults (at least 18 years old) and had immigrated to Canada within the past 15 years. Eight participants took part in a second interview, and four participants took part in a third interview. Results Using a constructivist grounded theory approach, “tackling the stumbling blocks of access” emerged as the core category. The basic social process (BSP), becoming self-sufficient, was a transitional process and had five stages: becoming a stranger; feeling helpless; navigating/seeking information; employing strategies; and becoming integrated and self-sufficient. We found that “tackling the stumbling blocks of access” was the main struggle throughout this journey. Some of the immigrants were able to overcome these challenges and became proficient in accessing health care services, but others were unable to make the necessary changes and thus stayed in earlier stages/phases of transition, and sometimes returned to their country of origin. Conclusion During the course of this journey a substantive grounded theory was developed that revealed the challenges and issues confronted by this particular group of immigrants. This process explains why some Iranian

    This qualitative study explored the identity development process of 11 undocumented college students living in the United States, focusing on how undocumented college students negotiate the interplay of acculturation, ethnic identity, and educational and career pursuits. A semistructured interview protocol was used and data analysis was iterative, consistent with grounded theory methodology. Four major themes emerged from the data: (a) "sewn with two threads" describes the salience of bicultural identity; (b) enhancement of positive attributes as a result of documentation struggles; (c) challenging reflections, addressing the ways in which documentation status challenges one's perception of oneself and the world; and (d) identity formation as an ongoing negotiation, capturing the long-term shifts in understanding of status implications and emotional response to this understanding. Findings are discussed in terms of their implications for educators, counseling psychologists, and career counselors. Suggestions regarding how mental health professionals can educate and empower undocumented immigrant youth are presented.

  3. The persistence of women in STEM: A constructivist grounded theory study

    NASA Astrophysics Data System (ADS)

    Gamm, Ryan

    Men and women have reached relative parity in most sectors of the United States workforce. Yet women remain underrepresented in science, technology, engineering, and mathematics (STEM) fields (AAUW, 2010). Underrepresentation persists despite several decades of research, legislation, and intervention focused on gender equality in STEM fields (Clewell, 2002). The underrepresentation or shortage of women in STEM fields is identifiable primarily in degree attainment, in workforce demographics, and in a gender wage gap. Situated in constructivist grounded theory, this study asks how do women in science, technology, engineering, and mathematics (STEM) fields, particularly those in established career positions, persist when encountering personal and institutional barriers, resistance, and hostility? I use an interpretive-constructivist lens to conduct a grounded theory study exploring the experiences of women who persist in STEM fields, their relation to extant literature on this topic, and the connections to K-12 education practices, specifically curriculum. To understand the connections to curriculum I employ Pinar's (2012) method of currere. Pinar (2012) contends currere "provides a strategy for students of curriculum to study the relations between academic knowledge and life history in the interests of self-understanding and social reconstruction" (p.44). This qualitative study explored nine female STEM workers stories of persistence as each respondent works in STEM fields were gender parity has yet to be established. This study presents a substantive theory: As women persist in STEM fields they reframe themselves to be situated in the overlapping intersection of the social processes that correspond to "engagement" and "persistence." This reframing is possible by interpreting one's present day circumstances by independently removing oneself from current circumstances to understand the cumulative effect of both past and present. The findings highlight the importance

    2014-01-01

    Purpose. To create a substantive mid-range theory explaining how the organizational cultures of undergraduate nursing programs shape the adoption and incorporation of mid-to high-level technical fidelity simulators as a teaching strategy within curricula. Method. A constructivist grounded theory was used to guide this study which was conducted in Ontario, Canada, during 2011-12. Semistructured interviews (n = 43) with participants that included nursing administrators, nursing faculty, and simulation leaders across multiple programs (n = 13) informed this study. Additionally, key documents (n = 67) were reviewed. Purposeful and theoretical sampling was used and data were collected and analyzed simultaneously. Data were compared among and between sites. Findings. The organizational elements that shape simulation in nursing (OESSN) model depicts five key organizational factors at the nursing program level that shaped the adoption and incorporation of simulation: (1) leaders working in tandem, (2) information exchange, (3) physical locale, (4) shared motivators, and (5) scaffolding to manage change. Conclusions. The OESSN model provides an explanation of the organizational factors that contributed to the adoption and incorporation of simulation into nursing curricula. Nursing programs that use the OESSN model may experience a more rapid or broad uptake of simulation when organizational factors that impact adoption and incorporation are considered and planned for.

    2016-01-01

    The purpose of this article is to amplify the results section of a grounded theory study on how men in nursing view and experience intention, intentionality, caring, and healing. This is the second grounded theory study addressing intentionality in healing. The first study included a female population. The theory that was generated-Intentionality: The Matrix of Healing (IMH)-is examined with these new data. The results are compared with issues generally faced by men in nursing and how they described their beliefs and experiences with intentionality and healing. The theory (IMH) is supported; the importance of action in this cohort was an additional emphasis. This article provides an expanded view of men in nursing and their experiences as nurses and with intentionality, caring, and healing and has implications for the development of holistic nursing theory as well.

    Nursing and social science scholars have examined the compatibility between feminist and grounded theory traditions in scientific knowledge generation, concluding that they are complementary, yet not without certain tensions. This line of inquiry is extended to propose a critical feminist grounded theory methodology. The construction of symbolic interactionist, feminist, and critical feminist variants of grounded theory methodology is examined in terms of the presuppositions of each tradition and their interplay as a process of theoretical triangulation.

    2012-01-01

    Nurses are the first role models for students in clinical settings. They can have a significant role on students' motivation. The purpose of this study was to explore the understanding of nursing students and instructors concerning the role of nurses in motivating nursing students through clinical education. The sampling was first started purposefully and continued with theoretical sampling. The study collected qualitative data through semistructured and interactive interviews with 16 nursing students and 4 nursing instructors. All interviews were recorded, transcribed, and analyzed using grounded theory approach. One important pattern emerged in this study was the “concerns of becoming a nurse,” which itself consisted of three categories: “nurses clinical competency,” “nurses as full-scale mirror of the future,” and “Monitoring and modeling through clinical education” (as the core variable). The findings showed that the nurses' manners of performance as well as the profession's prospect have a fundamental role in the process of formation of motivation through clinical education. Students find an insight into the nursing profession by substituting themselves in the place of a nurse, and as result, are or are not motivated towards the clinical education. PMID:22830005

    This descriptive-reflexive study was performed with the objective to present the characteristics of researchers who use the Grounded Theory method, and outline the development of aptitudes for the researcher to become a Grounded Theoretician. The theoretical discussion was based on the frameworks of this methodology and supported by the literature. The article presents the main demands of qualitative studies using Grounded Theory, and important behaviors, attitudes and characteristics developed by the researchers. It is concluded that learning about Grounded Theory involves more than operationalizing a group of procedures and techniques. It also involves facing challenges to change one's attitude as a researcher and develop new ways of thinking and researching, gathering knowledge based on data to form a theory.

    2004-01-01

    Objective: To gain insight regarding the mentoring processes involving students enrolled in athletic training education programs and to create a mentoring model. Design and Setting: We conducted a grounded theory study with students and mentors currently affiliated with 1 of 2 of the athletic training education programs accredited by the Commission on Accreditation of Allied Health Education Programs. Participants: Sixteen interviews were conducted, 13 with athletic training students and 3 with individuals identified as mentors. The students ranged in age from 20 to 24 years, with an average of 21.6 years. The mentors ranged from 24 to 38 years of age, with an average of 33.3 years. Participants were purposefully selected based on theoretic sampling and availability. Data Analysis: The transcribed interviews were analyzed using open-, axial-, and selective-coding procedures. Member checks, peer debriefings, and triangulation were used to ensure trustworthiness. Results: Students who acknowledged having a mentor overwhelmingly identified their clinical instructor in this role. The open-coding procedures produced 3 categories: (1) mentoring prerequisites, (2) interpersonal foundations, and (3) educational dimensions. Mentoring prerequisites included accessibility, approachability, and protégé initiative. Interpersonal foundations involved the mentor and protégé having congruent values, trust, and a personal relationship. The educational dimensions category involved the mentor facilitating knowledge and skill development, encouraging professional perspectives, and individualizing learning. Although a student-certified athletic trainer relationship can be grounded in either interpersonal or educational aspects, the data support the occurrence of an authentic mentoring relationship when the dimensions coalesced. Conclusions: Potential mentors must not only be accessible but also approachable by a prospective protégé. Mentoring takes initiative on behalf of a

    Children's right to participate in their own healthcare has increasingly become highlighted in national and international research as well as in government regulations. Nevertheless, children's participation in healthcare is unsatisfactorily applied in praxis. There is a growing body of research regarding children's participation, but research from the children's own perspective is scarce. The aim of this study was thus to explore the experiences and preferences for participation in healthcare situations among children with juvenile idiopathic arthritis (JIA) as a foundation for creating strategies to promote their participation in pediatric healthcare. Twenty children, aged 8 to 17 years, with JIA were interviewed individually and in focus groups. In order to increase the children's opportunities to express their own experiences, different interview techniques were used, such as draw-and-tell and role play with dolls. The analysis was conducted with a constructivist grounded theory. The result explores children's perspective of influencing processes promoting their participation in healthcare situations. The core category that emerged was, "Releasing fear and uncertainty opens up for confidence and participation," and the categories related to the core category are, "surrounded by a sense of security and comfort," and "strengthened and supported to become involved." In conclusion, the knowledge gained in this study offers new insights from the perspective of children themselves, and can constitute a valuable contribution to the understanding of necessary conditions for the development of specific interventions that promote participation among children in healthcare situations.

  17. Assimilating to Hierarchical Culture: A Grounded Theory Study on Communication among Clinical Nurses.

    The purpose of this study was to generate a substantive model that accounts for the explanatory social processes of communication in which nurses were engaged in clinical settings in Korea. Grounded theory methodology was used in this study. A total of 15 clinical nurses participated in the in-depth interviews. "Assimilating to the hierarchical culture" emerged as the basic social process of communication in which the participants engaged in their work environments. To adapt to the cultures of their assigned wards, the nurses learned to be silent and engaged in their assimilation into the established hierarchy. The process of assimilation consisted of three phases based on the major goals that nurses worked to achieve: getting to know about unspoken rules, persevering within the culture, and acting as senior nurse. Seven strategies and actions utilized to achieve the major tasks emerged as subcategories, including receiving strong disapproval, learning by observing, going silent, finding out what is acceptable, minimizing distress, taking advantages as senior nurse, and taking responsibilities as senior nurse. The findings identified how the pattern of communication in nursing organizations affected the way in which nurses were assimilated into organizational culture, from individual nurses' perspectives. In order to improve the rigid working atmosphere and culture in nursing organizations and increase members' satisfaction with work and quality of life, managers and staff nurses need training that focuses on effective communication and encouraging peer opinion-sharing within horizontal relationships. Moreover, organization-level support should be provided to create an environment that encourages free expression.

  18. Analysis of the decision-making process leading to appendectomy: a grounded theory study.

    2004-11-01

    The aim was to develop a theoretical understanding of the decision-making process leading to appendectomy. A qualitative interview study was performed in the grounded theory tradition using the constant comparative method to analyze data. The study setting was one county hospital and two local hospitals in Sweden, where 11 surgeons and 15 surgical nurses were interviewed. A model was developed which suggests that surgeons' decision making regarding appendectomy is formed by the interplay between their medical assessment of the patient's condition and a set of contextual characteristics. The latter consist of three interacting factors: (1) organizational conditions, (2) the professional actors' individual characteristics and interaction, and (3) the personal characteristics of the patient and his or her family or relatives. In case the outcome of medical assessment is ambiguous, the risk evaluation and final decision will be influenced by an interaction of the contextual characteristics. It was concluded that, compared to existing, rational models of decision making, the model presented identified potentially important contextual characteristics and an outline on when they come into play.

    Client-public health nurse relationships are considered to be important in nursing literature. However, little research in nursing has touched this area. The purpose of this paper is to describe a study of the patterns of interaction in terms of relationships between clients (mother and child under 1 year of age) and public health nurses in child health care at Finnish health centres. The qualitative data were collected by observing client-public health nurse interactions during visits. In total, 1554 interactions were observed over 2 years from 20 visits to child health centres. The grounded theory method was used in this study. Various relationships were identified between child and mother, child and public health nurse and mother and public health nurse. The relationship between child and mother during the visit was called a tender, protective and persuasive relationship. The relationship between child and public health nurse was called a persuasive and entertainment relationship. The main relationship between mother and public health nurse was called relationship supporting self-confidence. Suggestions for nursing practice and further research are made. PMID:1506539

    2011-01-01

    Simulation is the mainstay of laboratory education in health sciences, yet there is a void of pedagogy-the art and science of teaching. Nursing faculty does not have adequate evidence-based resources related to how students learn through simulation. The research questions that were addressed were as follows: (a) How do students learn using simulation? (b) What is the process of learning with simulations from the students' perspective? (c) What faculty teaching styles promote learning? and (d) How can faculty support students during simulation? Grounded theory methodology was used to explore how senior baccalaureate nursing students learn using simulation. Twenty-six students participated in this research study. Sixteen nursing students who completed two semesters of simulation courses volunteered for in-depth audio-taped interviews. In addition, there were two focus groups with five senior students in each group who validated findings and identified faculty teaching styles and supportive interventions. Negotiating the Role of the Professional Nurse was the core category, which included the following phases (I) feeling like an imposter, (II) trial and error, (III) taking it seriously, (IV) transference of skills and knowledge, and (V) professionalization. Faculty traits and teaching strategies for teaching with simulation were also identified. A conceptual model of the socialization process was developed to assist faculty in understanding the ways students learn with simulation and ways to facilitate their development. These findings provide a midrange theory for the pedagogy of simulation and will help faculty gain insight and help to assimilate into teaching-learning strategies. PMID:21925463

    The purpose of this study was to analyze how Swedish pediatric diabetes teams perceived and discussed fathers' involvement in the care of their child with type 1 diabetes. It also aimed to discuss how the teams' attitudes towards the fathers' involvement developed during the data collection process. The Constructivist Grounded Theory design was used and data were collected during three repeated focus group discussions with three Swedish pediatric diabetes teams. The core category of the teams' perception of fathers' involvement emerged as: If dad attends, we are happy - if mom doesn't, we become concerned. Initially the teams balanced their perception of fathers' involvement on the mother's role as the primary caregiver. In connection with the teams' directed attention on fathers, in the focus group discussions, the teams' awareness of the importance of fathers increased. As a consequence, the team members began to encourage fathers' engagement in their child's care. We conclude that by increasing the teams' awareness of fathers as a health resource, an active health promotion perspective could be implemented in pediatric diabetes care.

    The aim of this study was to identify the hidden patterns of behavior leading toward the decision to donate organs. Thirteen registrants at the Association for Organ Sharing in Korea were recruited. Data were collected using in-depth interview and the interview transcripts were analyzed using Glaserian grounded-theory methodology. The main problem of participants was "body attachment" and the core category (management process) was determined to be "pursuing life." The theme consisted of four phases, which were: "hesitating," "investigating," "releasing," and "re-discovering. " Therefore, to increase organ donations, it is important to find a strategy that will create positive attitudes about organ donation through education and public relations. These results explain and provide a deeper understanding of the main problem that Korean people have about organ donation and their management of decision-making processes. These findings can help care providers to facilitate the decision-making process and respond to public needs while taking into account the sociocultural context within which decisions are made.

    Background: Victims of sexual assault need comprehensive healthcare services to deal with the consequences of their experience. However, there are still many girls/women that delay seeking healthcare after they experience sexual assault. Objectives: To explore the process of health care and clinical services for victims of sexual assault in the health care centers of Iran. Patients and Methods: This was a qualitative study based on the grounded theory method. The sample consisted of 23 health care providers and 10 victims of sexual violence. Unstructured interviews and observations were used for data collection. Constant comparative analysis was used according to the Strauss and Corbin method. Results: The analysis of all data led to the extraction of four categories: “performing routines”, “victims’ expectations”, “conflict between expectations of victims and existing healthcare services”, and the core category of “neglect of healthcare providers to address the needs and expectations of victims”. Providers were offering health care to the victims of sexual violence regardless of their needs. Due to this neglect, victims sought illegal solutions to overcome the consequences that led to social stigma. Conclusions: The findings indicate the lack of mutual understanding between health care providers and victims of sexual violence in relation to the expectations and priorities of victims.

    Background: There are widespread misconceptions about the positive effects of opium on coronary artery disease (CAD). Thus, we performed a study to explore the opium addiction process contributing factors among CAD patients using a grounded theory approach. Methods: The sample comprised 30 addicted CAD patients and their family members, physicians, nurses and friends. Purposive and theoretical sampling was employed; semi-structured interviews were conducted. Coding and constant comparative analysis techniques were as proposed by Strauss and Corbin (1998). Results: The core category was ‘Fighting for Survival’, comprising three main themes, namely, ‘the gateway’, ‘blowing into the fire’ and ‘getting stuck in the mud’. Conclusion: Increasing knowledge about the adverse effects of opium on the cardiovascular system would reinforce prevention and rehabilitation measures. Involving patients’ family-members in addiction prevention and rehabilitation programs and referring patients to specialized rehabilitation centres could help patients quit opium. Healthcare providers (HCPs) should notice to the effects of opium consumption among CAD patients; nursing care must be holistic in nature. Although opium is stigmatised in Iran, HCPs must treat addicted CAD patients similar to other patients. Nursing students’ must be aware of the negative effects of illegal drugs on CAD patients and the misconceptions regarding the positive effects thereof. Any misconceptions must be probed and clarified. Rehabilitation centres must be supervised by cardiologists and HCPs. PMID:26793658

    The utility industry has devoted time and money to assure personnel within nuclear power plants are informed about occupational risks. Radiation-protection training programs are designed to present information to employees about occupational radiation and protective procedures. Work -related concerns are known to create stress, affect the morale of the workforce, influence collective bargaining, and increase compensation claims. This study was designed to determine perceptions of risk among employees of nuclear power plants and identify variables that influence these perceptions. Four power plants were included in the study, one in Canada and three in the United States. Data were generated through participant observations and interviews of 350 participants during a period of 3 weeks at each plant. Data were gathered and analyzed following procedures advanced by Grounded Theory, a naturalistic methodology used in this study. Training content, information, and communication materials were additional sources of data. Findings indicated employees believed health and safety risks existed within the work environment. Perceptions of risk were influenced by training quality, the work environment, nuclear myths and images of the general public, and fears of family members. Among the three groups of workers, administration personnel, security personnel, and radiation workers, the latter identified a larger number of risks. Workers perceived radiation risks, shift work, and steam pipe ruptures as high-level concerns. Experiencing stress, making mistakes, and fear of sabotage were concerns shared among all employee groups at various levels of concern. Strategies developed by employees were used to control risk. Strategies included teamwork, humor, monitoring, avoidance, reframing, and activism. When risks were perceived as uncontrollable, the employee left the plant. A coping strategy of transferring concerns about radiological risks to nonradiological risks were uncovered in

    Background General practitioners often encounter patients with medically unexplained symptoms. These patients share many common features, but there is little agreement about the best diagnostic framework for describing them. Aims This study aimed to explore how GPs make sense of medically unexplained symptoms. Design Semi-structured interviews were conducted with 24 GPs. Each participant was asked to describe a patient with medically unexplained symptoms and discuss their assessment and management. Setting The study was conducted among GPs from teaching practices across Australia. Methods Participants were selected by purposive sampling and all interviews were transcribed. Iterative analysis was undertaken using constructivist grounded theory methodology. Results GPs used a variety of frameworks to understand and manage patients with medically unexplained symptoms. They used different frameworks to reason, to help patients make sense of their suffering, and to communicate with other health professionals. GPs tried to avoid using stigmatising labels such as 'borderline personality disorder', which were seen to apply a 'layer of dismissal' to patients. They worried about missing serious physical disease, but managed the risk by deliberately attending to physical cues during some consultations, and focusing on coping with medically unexplained symptoms in others. They also used referrals to exclude serious disease, but were wary of triggering a harmful cycle of uncoordinated care. Conclusion GPs were aware of the ethical relevance of psychiatric diagnoses, and attempted to protect their patients from stigma. They crafted helpful explanatory narratives for patients that shaped their experience of suffering. Disease surveillance remained an important role for GPs who were managing medically unexplained symptoms.

    Qualitative research in general and the grounded theory approach in particular, have become increasingly prominent in medical education research in recent years. In this Guide, we first provide a historical perspective on the origin and evolution of grounded theory. We then outline the principles underlying the grounded theory approach and the procedures for doing a grounded theory study, illustrating these elements with real examples. Next, we address key critiques of grounded theory, which continue to shape how the method is perceived and used. Finally, pitfalls and controversies in grounded theory research are examined to provide a balanced view of both the potential and the challenges of this approach. This Guide aims to assist researchers new to grounded theory to approach their studies in a disciplined and rigorous fashion, to challenge experienced researchers to reflect on their assumptions, and to arm readers of medical education research with an approach to critically appraising the quality of grounded theory studies.

    Objectives To understand the concerns and challenges faced by general practitioners (GPs) and respiratory physicians about primary care management of acute exacerbations in patients with chronic obstructive pulmonary disease (COPD). Design 21 focus group discussions (FGDs) were performed in seven countries with a Grounded Theory approach. Each country performed three rounds of FGDs. Setting Primary and secondary care in Norway, Germany, Wales, Poland, Russia, The Netherlands, China (Hong Kong). Participants 142 GPs and respiratory physicians were chosen to include urban and rural GPs as well as hospital-based and out patient-clinic respiratory physicians. Results Management of acute COPD exacerbations is dealt with within a scope of concerns. These concerns range from ‘dealing with comorbidity’ through ‘having difficult patients’ to ‘confronting a hopeless disease’. The first concern displays medical uncertainty regarding diagnosis, medication and hospitalisation. These clinical processes become blurred by comorbidity and the social context of the patient. The second concern shows how patients receive the label ‘difficult’ exactly because they need complex attention, but even more because they are time consuming, do not take responsibility and are non-compliant. The third concern relates to the emotional reactions by the physicians when confronted with ‘a hopeless disease’ due to the fact that most of the patients do not improve and the treatment slows down the process at best. GPs and respiratory physicians balance these concerns with medical knowledge and practical, situational knowledge, trying to encompass the complexity of a medical condition. Conclusions Knowing the patient is essential when dealing with comorbidities as well as with difficult relations in the consultations on exacerbations. This study suggests that it is crucial to improve the collaboration between primary and secondary care, in terms of, for example, shared consultations

    Objectives To explore the experiences of family carers who manage technical health procedures at home and describe their learning process. Design A qualitative study using grounded theory. Participants New Zealand family carers (21 women, 5 men) who managed technical health procedures such as enteral feeding, peritoneal dialysis, tracheostomy care, a central venous line or urinary catheter. In addition, 15 health professionals involved in teaching carers were interviewed. Methods Semistructured interviews were coded soon after completion and preliminary analysis influenced subsequent interviews. Additional data were compared with existing material and as analysis proceeded, initial codes were grouped into higher order concepts until a core concept was described. Interviewing continued until no new ideas emerged and concepts were well defined. Results The response of carers to the role of managing technical health procedures in the home is presented in terms of five dispositions: (1) Embracing care, (2) Resisting, (3) Reluctant acceptance, (4) Relinquishing and (5) Being overwhelmed. These dispositions were not static and carers commonly changed between them. Embracing care included cognitive understanding of the purpose and benefits of a procedure; accepting a ‘technical’ solution; practical management; and an emotional response. Accepting embrace is primarily motivated by perceived benefits for the recipient. It may also be driven by a lack of alternatives. Resisting or reluctant acceptance results from a lack of understanding about the procedure or willingness to manage it. Carers need adequate support to avoid becoming overwhelmed, and there are times when it is appropriate to encourage them to relinquish care for the sake of their own needs. Conclusions The concept of embracing care encourages health professionals to extend their attention beyond simply the practical aspects of technical procedures to assessing and addressing carers’ emotional and

    Spector, Barbara S.; Gibson, Charles W.

    The purpose of this study was to explore middle school students' perceptions of what factors facilitated their learning of science. Florida's Educational Reform Act of 1983 funded programs providing the state's precollege students with summer learning opportunities in science. mathematics, and computers. The programs were intended to encourage the development of creative approaches to the teaching of these disciplines. Under this program, between 50 and 60 high-achieving middle school students were in residence on the University of South Florida campus for 12 consecutive days of study in the World of Water (WOW) program. There were two sessions per summer involving a total of 572 participants. Eighi specially trained teachers were in residence with the students. Between 50 and 70 experts from the university, government. business, and industry interacted with the students each year in an innovative science/technology/society (STS) program. An assignment toward the close of the program asked students to reflect on their experiences in residence at the university and write an essay comparing learning in the WOW program to learning in their schools. Those essays were the base for this study. This was a qualitative study using a discursive approach to emergent design to generate grounded theory. Document review, participant observation, and open-ended interviews were used to gather and triangulate data in five phases. Some of the factors that middle school students perceived as helpful to learning science were (a) experiencing the situations about which they were learning; (b) having live presentations by professional experts; (c) doing hands-on activities: (d) being active learners; (e) using inductive reasoning to generate new knowledge; (f) exploring transdisciplinary approaches to problem solving; (g) having adult mentors; (h) interacting with peers and adults; (i) establishing networks; (j) having close personal friends who shared their interest in learning; (k

    Norcross, Robert

    Aircraft maintenance technician decision-making and actions have resulted in aircraft system errors causing aircraft incidents and accidents. Aircraft accident investigators and researchers examined the factors that influence aircraft maintenance technician errors and categorized the types of errors in an attempt to prevent similar occurrences. New aircraft technology introduced to improve aviation safety and efficiency incur failures that have no information contained in the aircraft maintenance manuals. According to the Federal Aviation Administration, aircraft maintenance technicians must use only approved aircraft maintenance documents to repair, modify, and service aircraft. This qualitative research used a grounded theory approach to explore the decision-making processes and actions taken by aircraft maintenance technicians when confronted with an aircraft problem not contained in the aircraft maintenance manuals. The target population for the research was Federal Aviation Administration licensed aircraft and power plant mechanics from across the United States. Nonprobability purposeful sampling was used to obtain aircraft maintenance technicians with the experience sought in the study problem. The sample population recruitment yielded 19 participants for eight focus group sessions to obtain opinions, perceptions, and experiences related to the study problem. All data collected was entered into the Atlas ti qualitative analysis software. The emergence of Aircraft Maintenance Technician decision-making themes regarding Aircraft Maintenance Manual content, Aircraft Maintenance Technician experience, and legal implications of not following Aircraft Maintenance Manuals surfaced. Conclusions from this study suggest Aircraft Maintenance Technician decision-making were influenced by experience, gaps in the Aircraft Maintenance Manuals, reliance on others, realizing the impact of decisions concerning aircraft airworthiness, management pressures, and legal concerns

    2005-12-01

    Geoscience educators use a variety of resources and resource formats in their classroom teaching to facilitate student understanding of concepts and processes that define subject areas considered in the realm of geoscience. In this study of information needs and behaviors of geoscience educators, the researcher found that participants preferred visual media such as personal photographic and digital images, as well as published figures, animations, and cartoons, and that participants bypassed their academic libraries to meet these information needs. In order to investigate the role of information in developing introductory geoscience course and instruction, a grounded theory study was conducted through a qualitative paradigm with an interpretive approach and naturalistic inquiry. The theoretical and methodological framework was constructivism and sense-making. Research questions were posited on the nature of geoscience subject areas and the resources and resource formats used in conveying geoscience topics to science and non-science majors, as well as educators' preferences and concerns with curriculum and instruction. The underlying framework was to investigate the place of the academic library and librarian in the sense-making, constructivist approach of geoscience educators. A purposive sample of seven geoscience educators from four universities located in mid-western United States was identified as exemplary teachers by department chairpersons. A triangulation of data collection methods included semi-structured interviews, document reviews, and classroom observations. Data were analyzed using the constant comparative method, which included coding, categorizing, and interpreting for patterns and relationships. Contextual factors were identified and a simple model resulted showing the role of information in teaching for these participants. While participants developed lectures and demonstrations using intrapersonal knowledge and personal collections, one barrier

    Background Data about delayed tuberculosis diagnosis in Northern Russia are scarce yet such knowledge could enhance the care of tuberculosis. The Arkhangelsk region is situated in the north of Russia, where the population is more than one million residents. The aim of the study was to understand factors influencing diagnostic delay among patients with tuberculosis in the Arkhangelsk region and to develop a theoretical model in order to explain diagnostic delay from the patients’ perspectives. Methods Twenty-three patients who had experienced diagnostic delay of tuberculosis were interviewed in Arkhangelsk. Using a qualitative approach, we conducted focus-group discussions for data gathering using Grounded Theory with the Paradigm Model to analyse the phenomenon of diagnostic delay. Results The study resulted in a theoretical model of the pathway of delay of tuberculosis diagnosis in the Arkhangelsk region in answer to the question: “Why and how do patients in the Arkhangelsk region delay tuberculosis diagnosis?” The model included categories of causal conditions, context and intervening conditions, action/interaction strategies, and consequences. The causal condition and main concern of the patients was that they were overpowered by hopelessness. Patients blamed policy, the administrative system, and doctors for their unfortunate life circumstances. This was accompanied by avoidance of health care, denial of their own health situations, and self-treatment. Only a deadly threat was a sufficient motivator for some patients to seek medical help. “Being overpowered by hopelessness” was identified as the core category that affected their self-esteem and influenced their entire lives, including family, work and social relations, and appeared even stronger in association with alcohol use. This category reflected the passive position of many patients in this situation, including their feelings of inability to change anything in their lives, to obtain employment

    Glaserian grounded theory is a powerful research methodology for understanding client behaviour in a particular area. It is therefore especially relevant for nurse researchers. Nurse researchers use grounded theory more frequently than other qualitative analysis research methods because of its ability to provide insight into clients' experiences and to make a positive impact. However, there is much confusion about the use of grounded theory.The author delineates key components of grounded theory methodology, areas of concern, and the resulting implications for nursing knowledge development. Knowledge gained from Glaserian grounded theory research can be used to institute measures for enhancing client-nurse relationships, improving quality of care, and ultimately improving client quality of life. In addition, it can serve to expand disciplinary knowledge in nursing because the resulting substantive theory is a middle-range theory that can be subjected to later quantitative testing.

    The doctor-patient relationship (DPR) is one of the most important subjects in medical sociology and health policy. Due to mutual understanding, undistorted DPRs not only result in satisfaction of both doctors and patients, but also help to reduce financial burdens for patients and the health care system. The purpose of this research was to identify a DPR based on the qualitative paradigm model which is called the grounded theory (GT) methodology. The data were collected from 3 focus groups, the participants of which consisted of 21 faculty members of Shiraz University of Medical Sciences, Shiraz, Iran. The content of the interviews, following the transcription stage, was organized based on open, axial, and selective coding. Results showed that DPR was distorted which was the consequence of an inefficient structure in the healthcare system which is related to several cultural barriers. In this situation, agency is determinant so the doctor's personality determines the direction of DPR. Consequences of such scenarios are the patient’s distrust, patient's dissatisfaction, lack of mutual understanding, patient suppression, and patient deception. Therefore, the health care system should emphasize on reforming its inefficient infrastructures, so that, besides being controlled and surveyed, physicians are socialized ethically. PMID:27390617

    To develop a model of healthy aging from the perspective of Thais, a grounded theory approach, including in-depth interviews and focus groups, was used. A purposive sample of 39 community-dwelling adults aged 40-85 years old was interviewed. The Thai healthy aging model composed of three themes: normality, nature, and dharma. In Thai, they are called tham-ma-da, tham-ma-chat, and tham-ma, or "Thai 3Ts". The theme of normality encompasses subthemes of staying physically active by being involved in plenty of physical activities, and being mentally active with creative and thoughtful hobbies and work. The theme of nature encompasses subthemes of living simply and being careful with money. The theme of dharma encompasses subthemes of enjoyment through helping family and participating in community activities, staying away from stress and worries by talking openly and honestly with someone, making merit, and helping other people without expecting anything in return. A greater understanding of healthy aging is a benefit for older adults and healthcare providers in an intervention-design process. Research can contribute valuable information to shape policy for healthy aging as well.

  6. Determining quality in doctoral programming: A grounded theory study of biological sciences, English studies, and special education

    NASA Astrophysics Data System (ADS)

    Fansler, A. Gigi

    This study uses the grounded theory approach to identify how 12 faculty members at Illinois State University define the key determinants of a quality doctoral program. Two sets of interviews were conducted, lasting from 45 to 90 minutes. The first round of interviews was guided by the following open-ended questions: (1) How do you define a quality doctoral program? (2) What has led you to define quality in that way? and (3) What events or actions have you experienced that have been evidence of "quality?" While these three served as the primary questions, many follow-up questions and prompts were used throughout the entire interview process. A subsequent interview was conducted with the participants in order to explore the 12 emergent categories. The theory was generated using the transcriptions from both rounds of interviews and a conceptual map that was revised throughout the process. The researcher used open-coding, axial coding, and selective coding throughout the study until saturation of the data was achieved, and relationships among the categories were formed. The following nine factors of the model emerged from the data: (a) professional mentorship; (b) faculty productivity; (c) program accountability and/or evaluation; (d) students who publish; (e) solid educational experience; (f) quality of students; (g) student placement; (h) experience as a faculty member; (i) experiences as a doctoral student. The first seven describe how the 12 faculty members defined a quality doctoral program. The last two address the factors that led the participants to define quality in the way they did. This study provides leaders of higher education institutions a glimpse of one stakeholder group's perceptions of what constitutes a quality doctoral program. Such information can be used as a starting point for assessing quality of doctoral programs in an era of accountability.

    Living with a chronic disease like chronic heart failure (CHF) results in disruptions, losses, and setbacks in the participants' daily lives that affect health and well-being. By using grounded theory method, we illuminate whether persons with CHF experience discontinuity in life and, if so, what helps them to preserve and strengthen continuity in their daily lives. Thirteen individual interviews and one group interview with five participants, aged 62 to 88 years, were carried out. Through data collection and data analysis, we constructed three concepts that make up a model illustrating the participants' experiences in daily life in relation to corporeality, temporality, and identity: experiences of discontinuity, recapturing approaches, and reconciliation. The first concept, experiences of discontinuity, was constructed from the following categories: the alienated body, the disrupted time, and the threatened self. The second concept, recapturing approaches, consists of categories with continuity creative constructions: repossessing the body, maintaining a façade, seizing the day, restoring the balance of time, and preserving self. These actions are intended to overcome problems and master changes in order to maintain balance in daily life through constructions that recreate normality and predictability. The third concept, reconciliation, was constructed from three categories: feel normal, set to adjust, and be positioned. These categories describe how the participants minimize their experiences of discontinuity by recapturing approaches in order to reconcile with various changes and maintain continuity in daily life. Our findings provide a fresh perspective on continuity that may contribute to the development of significant interventions in continuity of care for persons with CHF. However, continuity requires that healthcare systems support each patient's ability to manage change, reorientation, and adjustment to the new situation in order to make it easier for

  9. Tailoring a response to youth binge drinking in an Aboriginal Australian community: a grounded theory study

    PubMed Central

    2013-01-01

    Background While Aboriginal Australian health providers prioritise identification of local community health needs and strategies, they do not always have the opportunity to access or interpret evidence-based literature to inform health improvement innovations. Research partnerships are therefore important when designing or modifying Aboriginal Australian health improvement initiatives and their evaluation. However, there are few models that outline the pragmatic steps by which research partners negotiate to develop, implement and evaluate community-based initiatives. The objective of this paper is to provide a theoretical model of the tailoring of health improvement initiatives by Aboriginal community-based service providers and partner university researchers. It draws from the case of the Beat da Binge community-initiated youth binge drinking harm reduction project in Yarrabah. Methods A theoretical model was developed using the constructivist grounded theory methods of concurrent sampling, data collection and analysis. Data was obtained from the recordings of reflective Community-Based Participatory Research (CBPR) processes with Aboriginal community partners and young people, and university researchers. CBPR data was supplemented with interviews with theoretically sampled project participants. The transcripts of CBPR recordings and interviews were imported into NVIVO and coded to identify categories and theoretical constructs. The identified categories were then developed into higher order concepts and the relationships between concepts identified until the central purpose of those involved in the project and the core process that facilitated that purpose were identified. Results The tailored alcohol harm reduction project resulted in clarification of the underlying local determinants of binge drinking, and a shift in the project design from a social marketing awareness campaign (based on short-term events) to a more robust advocacy for youth mentoring into

    Objective The objective of this study was to examine the factors that influence decision-making to forgo transplantation in favour of remaining on nocturnal haemodialysis (NHD). Design A grounded theory approach using in-depth telephone interviewing was used. Setting Participants were identified from 2 tertiary care renal programmes in Canada. Participants The study participants were otherwise eligible patients with end-stage renal disease who have opted to remain off of the transplant list. A total of 7 eligible participants were interviewed. 5 were male. The mean age was 46 years. Analysis A constant comparative method of analysis was used to identify a core category and factors influencing the decision-making process. Results In this grounded theory study of people receiving NHD who refused kidney transplantation, the core category of ‘why take a chance when things are going well?’ was identified, along with 4 factors that influenced the decision including ‘negative past experience’, ‘feeling well on NHD’, ‘gaining autonomy’ and ‘responsibility’. Conclusions This study provides insight into patients' thought processes surrounding an important treatment decision. Such insights might help the renal team to better understand, and thereby respect, patient choice in a patient-centred care paradigm. Findings may also be useful in the development of education programmes addressing the specific concerns of this population of patients. PMID:27194322

    Black adolescents in the US experience perinatal loss at a higher rate than other races and ethnicities. The experience of eight Black urban adolescents through the first three months after perinatal loss was studied using grounded theory. The process of “enduring to gain new perspective” began with “denying and hesitating” when surprised by unplanned pregnancy but led to “getting ready for this whole new life,” followed by shock of “suffering through the loss,” “all that pain for nothing,” and “mixed emotions going everywhere.” Over time, the adolescents began “reaching out for support” and eventually “preserving the memory and maintaining relationship,” “searching for meaning and asking why,” and gaining new perspective on life.” Parallels are noted to extant bereavement theory.

    The health of older people is a priority in many countries as the world's population ages. Attitudes towards help seeking behaviours in older people remain a largely unexplored field of research. This is particularly true for older minority groups where the place that they have migrated to presents both cultural and structural challenges. The UK, like other countries, has an increasingly aging Chinese population about who relatively little is known. This study used a qualitative grounded theory design following the approach of Glaser (1978). Qualitative data were collected using semi-structured interviews with 33 Chinese elders who were aged between 60 and 84, using purposive and theoretical sampling approaches. Data were analysed using the constant comparative method until data saturation occurred and a substantive theory was generated. “Being healthy” (the core category) with four interrelated categories: self-management, normalizing/minimizing, access to health services, and being cured form the theory. The theory was generated around the core explanations provided by participants and Chinese elders’ concerns about health issues they face in their daily life. We also present data about how they direct their health-related activities towards meeting their physical and psychological goals of being healthy. Their differential understanding of diseases and a lack of information about health services were potent predictors of non–help seeking and “self” rather than medical management of their illnesses. This study highlights the need for intervention and health support for Chinese elders. PMID:25361531

    The provision of inter professional learning (IPL) within undergraduate programmes is now well established within many Higher Education Institutions (HEIs). IPL aims to better equip nurses and other health professionals with effective collaborative working skills and knowledge to improve the quality of patient care. Although there is still ambiguity in relation to the optimum timing and method for delivering IPL, effective facilitation is seen as essential. This paper reports on a grounded theory study of university educators' perceptions of the knowledge and skills needed for their role adequacy as IPL facilitators. Data was collected using semi structured interviews with nine participants who were theoretically sampled from a range of professional backgrounds, with varied experiences of education and involvement in facilitating IPL. Constant comparative analysis was used to generate four data categories: creating and sustaining an IPL group culture through transformational IPL leadership (core category), readiness for IPL facilitation, drawing on past interprofessional learning and working experiences and role modelling an interprofessional approach. The grounded theory generated from this study, although propositional, suggests that role adequacy for IPL facilitation is dependent on facilitator engagement in a process of 'transformational interprofessional learning leadership' to create and sustain a group culture.

    Feminist research is evolving, and with it new methods of doing science. In this feminist post-positivist era, grounded theory, while less inclusive and descriptive than ethnography, allows for complex analysis of complex questions. While Glaser & Strauss (the originators of this methodology) have written about grounded theory in an esoteric way, others have written extensively about this method in a much clearer and less rigid fashion. In this paper we discuss how grounded theory could be used in a creative and constantly evolving manner for feminist research.

    PubMed

    Jezewski, M A

    1995-03-01

    This article describes the evolution of the middle-range substantive theory of culture brokering. The theory was generated by first conducting a concept analysis that yielded 12 attributes of the concept of culture brokering. The concept analysis was accomplished using the anthropology, health-related, and business literature. In addition, data from an interpretive ethnographic study were used to further develop the concept of culture brokering. The theory was then generated from four grounded theory studies. Each study was used to frame the grounded theory model and to strengthen and refine the categories and links between categories within the basic social process of culture brokering. The culture brokering theory can guide the practice of nurses in situations where conflict is present in the health care interaction. The theory is grounded in the experiences of nurses attempting conflict resolution in the context of health care interactions. PMID:7778888

    Objective To develop a theoretical model concerning male victims' processes of disclosing experiences of victimisation to healthcare professionals in Sweden. Design Qualitative interview study. Setting Informants were recruited from the general population and a primary healthcare centre in Sweden. Participants Informants were recruited by means of theoretical sampling among respondents in a previous quantitative study. Eligible for this study were men reporting sexual, physical and/or emotional violence victimisation by any perpetrator and reporting that they either had talked to a healthcare provider about their victimisation or had wanted to do so. Method Constructivist grounded theory. 12 interviews were performed and saturation was reached after 9. Results Several factors influencing the process of disclosing victimisation can be recognised from previous studies concerning female victims, including shame, fear of negative consequences of disclosing, specifics of the patient–provider relationship and time constraints within the healthcare system. However, this study extends previous knowledge by identifying strong negative effects of adherence to masculinity norms for victimised men and healthcare professionals on the process of disclosing. It is also emphasised that the process of disclosing cannot be separated from other, even seemingly unrelated, circumstances in the men's lives. Conclusions The process of disclosing victimisation to healthcare professionals was a complex process involving the men's experiences of victimisation, adherence to gender norms, their life circumstances and the dynamics of the actual healthcare encounter.

    2012-01-01

    Background Even though remarkable progress has been achieved, HIV/AIDS continues to be a major global health priority. HIV discordant relationship is one of the emerging issues in HIV prevention endeavour. In Ethiopia, very little is known about HIV-serodiscordant couples particularly how they manage their sexual relationship and fertility desire. Therefore, we conduct this study with the aim of exploring the experiences of HIV discordant couples about their sexual life, and fertility desire in the context of long-term relationships in Addis Ababa, Ethiopia. Methods A grounded theory approach was employed using in-depth interviews among 36 informants in ART/PMTCT centers of three public hospitals, a health center and one PLHIV association in Addis Ababa. Theoretical sampling was used to recruit 28 clients who lived in a discordant relationship and eight health care providers as key informants. Data collection and analysis were undertaken simultaneously using a constant comparison. The analysis was facilitated using OpenCode software. Results A grounded theory pertaining to sexual life and desire to have a child among HIV discordant couples emerged as “maintaining the relationship” as a core category. Couples pass through a social process of struggle to maintain their relationship. The causal conditions for couples to enter into the process of struggle to maintain their relationship were collectively categorized as “Entering in-to a transition” (knowing HIV serostatus) and this includes mismatch of desire to have a child, controversy on safe sex versus desire to have a child, and undeniable change in sexual desire and practice through time were the features in entering into-transition. Then after the transition, couples engaged in certain actions/strategies that are categorized as “dealing with discordancy” such as entertaining partner’s interest by scarifying once self interest to maintain their relationship. Conclusions HIV discordant couples

    ABSTRACT The overall purpose of this study was to create a model of positive youth development (PYD) through sport grounded in the extant qualitative literature. More specifically, the first objective was to review and evaluate qualitative studies of PYD in sport. The second objective was to analyze and synthesize findings from these studies. Following record identification and screening, 63 articles were retained for analysis. Meta-method analysis revealed strengths of studies were the use of multiple data collection and validity techniques, which produced high-quality data. Weaknesses were limited use of ‘named’ methodologies and inadequate reporting of sampling procedures. Philosophical perspectives were rarely reported, and theory was used sparingly. Results of an inductive meta-data analysis produced three categories: PYD climate (adult relationships, peer relationships, and parental involvement), life skills program focus (life skill building activities and transfer activities), and PYD outcomes (in personal, social, and physical domains). A model that distinguishes between implicit and explicit processes to PYD is presented. PMID:27695511

    While sanitation interventions have focused primarily on child health, women's unique health risks from inadequate sanitation are gaining recognition as a priority issue. This study examines the range of sanitation-related psychosocial stressors during routine sanitation practices in Odisha, India. Between August 2013 and March 2014, we conducted in-depth interviews with 56 women in four life stages: adolescent, newly married, pregnant and established adult women in three settings: urban slums, rural villages and indigenous villages. Using a grounded theory approach, the study team transcribed, translated, coded and discussed interviews using detailed analytic memos to identify and characterize stressors at each life stage and study site. We found that sanitation practices encompassed more than defecation and urination and included carrying water, washing, bathing, menstrual management, and changing clothes. During the course of these activities, women encountered three broad types of stressors-environmental, social, and sexual-the intensity of which were modified by the woman's life stage, living environment, and access to sanitation facilities. Environmental barriers, social factors and fears of sexual violence all contributed to sanitation-related psychosocial stress. Though women responded with small changes to sanitation practices, they were unable to significantly modify their circumstances, notably by achieving adequate privacy for sanitation-related behaviors. A better understanding of the range of causes of stress and adaptive behaviors is needed to inform context-specific, gender-sensitive sanitation interventions. PMID:26164119

    Erectile dysfunction (ED) can impair the quality of life and the relationship. An early treatment is necessary to avoid the development of comorbid complaints. To arise the help-seeking behavior and to improve the treatment of affected men, it is necessary to be aware of the treatment expectations. The objective of this study was to investigate the treatment expectations of men with ED and their female partners. This is an explorative qualitative study using semistructured telephone interviews with 12 men with ED and their female partners. Interviews were tape-recorded, transcribed and analyzed on the basis of the grounded theory. We could identify various treatment expectations, which could be differentiated into expectations according to the conditions (for example, low costs and an early access), the handling of the practitioner (for example, showing interest and taking the patient seriously or incorporate the female partner), the treatment itself (for example, clearing the causes and helpful medication) and the treatment outcome (for example, having no ED and more sexual desire). Considering the identified expectations could increase treatment motivation and compliance. We derive five theses from our data, how to implement our findings.

  20. Perception of quality of care among residents of public nursing-homes in Spain: a grounded theory study

    2013-01-01

    Background The quality of care in nursing homes is weakly defined, and has traditionally focused on quantify nursing homes outputs and on comparison of nursing homes’ resources. Rarely the point of view of clients has been taken into account. The aim of this study was to ascertain what means “quality of care” for residents of nursing homes. Methods Grounded theory was used to design and analyze a qualitative study based on in-depth interviews with a theoretical sampling including 20 persons aged over 65 years with no cognitive impairment and eight proxy informants of residents with cognitive impairment, institutionalized at a public nursing home in Spain. Results Our analysis revealed that participants perceived the quality of care in two ways, as aspects related to the persons providing care and as institutional aspects of the care’s process. All participants agreed that aspects related to the persons providing care was a pillar of quality, something that, in turn, embodied a series of emotional and technical professional competences. Regarding the institutional aspects of the care’s process, participants laid emphasis on round-the-clock access to health care services and on professional’s job stability. Conclusions This paper includes perspectives of the nursing homes residents, which are largely absent. Incorporating residents’ standpoints as a complement to traditional institutional criteria would furnish health providers and funding agencies with key information when it came to designing action plans and interventions aimed at achieving excellence in health care.

    Intimate partner violence is a serious and pervasive problem in U.S. society, with 25% of women and 7.6% of men reporting physical abuse by an intimate partner each year. Understanding the risk factors for development of violence is essential toward the development of interventions to reduce partner violence. Much of the understanding about the development of partner violence is based on research with victims rather than perpetrators. The study was conducted with men convicted of assault on an intimate female partner. Grounded theory was the method used to analyze data from interviews with 16 men participating in a batterers' intervention and prevention program. From the data, the Violent Couples Model was developed. The primary elements of the Violent Couples Model are justifying violence, minimizing violence, childhood exposure to violence, ineffective anger management, childhood experience of violence, and ineffective conflict resolution. Social and familial factors serve as moderating elements. Contextual elements of the model include power and control, social isolation, desensitization, insecure maternal relationships, the view of violence as a private problem, ambivalent intimate relationships, objectification of women, immaturity, lack of awareness about what constitutes violence, mistrust, traditional views of the roles of women, financial issues, and jealousy. Interventions indicated in the model are primary, or preventive, in nature. The model focuses on prevention efforts with the family as a whole, rather than on batterers alone. PMID:16020047

    Background Since life recovery after disasters is a subjective and multifaceted construct influenced by different factors, and survivors’ main concerns and experiences are not clear, the researchers intended to explore this process. Materials and Methods This study was conducted in 2011 - 2014 based on the grounded theory approach. Participants were selected by purposeful sampling followed by theoretical sampling to achieve conceptual and theoretical saturation. Data were collected through interviews, observation, focus group discussion, and document reviews. Data were analyzed by Strauss and Corbin’s (2008) recommended approach. Results Transcribed data from 26 interviews (managers, health care providers, and receivers), field notes, and other documents were analyzed, and 1,652 open codes were identified. The codes were categorized, using constant comparative analysis, into five main categories including reactive exposure, subsiding emotions, need for comprehensive health recovery, improvement of normalization (new normality achievement), and contextual factors. The process of life recovery after disaster was also explored. Conclusions The results clarified a deep perception of participants’ experiences after disaster. The path of life recovery after disasters involves participants’ striving to achieve a comprehensive health recovery, which starts with the need for all-inclusive health recovery as a main concern; this is the motivator for a responding strategy. This strategy is participatory, and the process is progressive; achievement of a new normality is the final goal, with new development and levels of empowerment. PMID:27703797

    The aim of this study was to identify Australian medical students' complementary medicine information needs. Thirty medical students from 10 medical education faculties across Australian universities were recruited. Data were generated using in-depth semi-structured interviews and constructivist grounded theory method was used to analyze and construct data. Students sought complementary medicine information from a range of inadequate sources, such as pharmacological texts, Internet searches, peer-reviewed medical journals, and drug databases. The students identified that many complementary medicine resources may not be regarded as objective, reliable, differentiated, or comprehensive, leaving much that medical education needs to address. Most students sought succinct, easily accessible, evidence-based information to inform safe and appropriate clinical decisions about complementary medicines. A number of preferred resources were identified that can be recommended and actively promoted to medical students. Therefore, specific, evidence-based complementary medicine databases and secondary resources should be subscribed and recommended to medical schools and students, to assist meeting professional responsibilities regarding complementary medicines. These findings may help inform the development of appropriate medical information resources regarding complementary medicines.

    The aim of this study was to generate a theoretical model of underlying social processes that trigger stress in adolescent girls' everyday life. In-depth interviews regarding the experiences of stress at home, school and during leisure time were conducted with 14 17-year-old schoolgirls. Data were analysed by means of the grounded theory method. Stress was triggered in the interaction between responsibility and the way in which the girls were encountered. Triggered emotional reactions took the form of four dimensions of stress included ambivalence, frustration, despair and downheartedness. These reactions were dependent on whether the girls voluntary assumed responsibility for various situations or whether they were forced, or felt they were being forced, to assume responsibility in interaction with an encounter characterized by closeness or distance. These forms of stress reactions could appear in one dimension and subsequently shift to another. From the public health perspective, the generated stress model can be used in the planning and implementation of future actions to prevent stress and promote well-being related to stress in adolescent girls.

  13. A Generalized Approach for the Interpretation of Geophysical Well Logs in Ground-Water Studies - Theory and Application

    USGS Publications Warehouse

    Paillet, Frederick L.; Crowder, R.E.

    1996-01-01

    Quantitative analysis of geophysical logs in ground-water studies often involves at least as broad a range of applications and variation in lithology as is typically encountered in petroleum exploration, making such logs difficult to calibrate and complicating inversion problem formulation. At the same time, data inversion and analysis depend on inversion model formulation and refinement, so that log interpretation cannot be deferred to a geophysical log specialist unless active involvement with interpretation can be maintained by such an expert over the lifetime of the project. We propose a generalized log-interpretation procedure designed to guide hydrogeologists in the interpretation of geophysical logs, and in the integration of log data into ground-water models that may be systematically refined and improved in an iterative way. The procedure is designed to maximize the effective use of three primary contributions from geophysical logs: (1) The continuous depth scale of the measurements along the well bore; (2) The in situ measurement of lithologic properties and the correlation with hydraulic properties of the formations over a finite sample volume; and (3) Multiple independent measurements that can potentially be inverted for multiple physical or hydraulic properties of interest. The approach is formulated in the context of geophysical inversion theory, and is designed to be interfaced with surface geophysical soundings and conventional hydraulic testing. The step-by-step procedures given in our generalized interpretation and inversion technique are based on both qualitative analysis designed to assist formulation of the interpretation model, and quantitative analysis used to assign numerical values to model parameters. The approach bases a decision as to whether quantitative inversion is statistically warranted by formulating an over-determined inversion. If no such inversion is consistent with the inversion model, quantitative inversion is judged not

    Background Obstructed labour is still a major cause of maternal and perinatal morbidity and mortality in Uganda, where many women give birth at home alone or assisted by non-skilled birth attendants. Little is known of how the community view obstructed labour, and what actions they take in cases where this complication occurs. Objective The objective of the study was to explore community members’ understanding of and actions taken in cases of obstructed labour in south-western Uganda. Design Grounded theory (GT) was used to analyse data from 20 focus group discussions (FGDs), 10 with women and 10 with men, which were conducted in eight rural and two urban communities. Results A conceptual model based on the community members’ understanding of obstructed labour and actions taken in response is presented as a pathway initiated by women's desire to ‘protecting own integrity’ (core category). The pathway consisted of six other categories closely linked to the core category, namely: (1) ‘taking control of own birth process’; (2) ‘reaching the limit – failing to give birth’ (individual level); (3) ‘exhausting traditional options’; (4) ‘partner taking charge’; (5) ‘facing challenging referral conditions’ (community level); and finally (6) ‘enduring a non-responsive healthcare system’ (healthcare system level). Conclusions There is a need to understand and acknowledge women's reluctance to involve others during childbirth. However, the healthcare system should provide acceptable care and a functional referral system closer to the community, thus supporting the community's ability to seek timely care as a response to obstructed labour. Easy access to mobile phones may improve referral systems. Upgrading of infrastructure in the region requires a multi-sectoral approach. Testing of the conceptual model through a quantitative questionnaire is recommended. PMID:22216018

    PubMed

    Plummer, Marilyn; Young, Lynne E

    2010-04-01

    Grounded theory has served feminist research endeavors since the mid-1990s. Researchers from a variety of disciplines claim methodological compatibility and incorporate feminist principles into their grounded theory studies. This article seeks to demonstrate the epistemological affinity between feminist inquiry and grounded theory. Although this relationship is not necessarily unique, the authors contend that when combined, it loosens the androcentric moorings of the empirical processes underpinning grounded theory, enabling the researchers to design inquiry with greater potential to reveal issues particular to the lives and experiences of marginalized women. The article begins by retracing the roots of grounded theory and feminist inquiry to identify six key areas where the underpinnings of GT are enriched by a feminist perspective when working with women. In addition, the authors draw on the literature and their experience from a 2005 study of peer support and lone mothers' health to demonstrate the advantages of combining these theoretical perspectives. Finally, the authors recommend that nurse researchers draw on feminist principles to guide their use of grounded theory to better serve the interests of women by surfacing issues of gender and power that influence the health experience.

    Background The patient-nurse relationship is a traditional concern of healthcare research. However, patient-nurse interaction is under examined from a social perspective. Current research focuses mostly on specific contexts of care delivery and experience related to medical condition or illness, or to nurses’ speciality. Consequentially, this paper is about the social meanings and understandings at play within situated patient-nurse interaction in the community practice setting in a transforming healthcare service. Methods Grounded theory methodology was used and the research process was characterised by principles of theoretical sensitivity and constant comparative analysis. The field of study was four health centres in the community. The participants were patients and nurses representative of those attending or working in the health centres and meeting there by scheduled appointment. Data collection methods were observations, informal interviews and semi-structured interviews. Results Key properties of ‘Being a good patient, being a good nurse’, ‘Institutional experiences’ and ‘Expectations about healthcare’ were associated with the construction of a category entitled ‘Experience’. Those key properties captured that in an evolving healthcare environment individuals continually re-constructed their reality of being a patient or nurse as they endeavoured to perform appropriately; articulation of past and present healthcare experiences was important in that process. Modus operandi in role as patient was influenced by past experiences in healthcare and by those in non-healthcare institutions in terms of engagement and involvement (or not) in interaction. Patients’ expectations about interaction in healthcare included some uncertainly as they strived to make sense of the changing roles and expertise of nurses and, differentiating between the roles and expertise of nurses and doctors. Conclusions The importance of social meanings and understandings

  3. Health as expanding consciousness: a nursing perspective for grounded theory research.

    Brown, Janet Witucki

    2011-07-01

    Margaret Newman's theory of health as expanding consciousness provides an excellent nursing perspective for nursing grounded theory research studies. Application of this nursing theory to grounded theory research provides a unitary-transformative paradigm perspective to the sociological underpinnings of grounded theory methodology. The fit between this particular nursing theory and grounded theory methodology is apparent when purpose, timing, process, and health outcomes of the two are compared. In this column, the theory of health as expanding consciousness is described and the theory's research as praxis methodology is compared to grounded theory methodology. This is followed by a description of how the theory of health as expanding consciousness can be utilized as a perspective for nursing grounded theory research.

    The epistemological underpinnings of grounded theory make it valuable in the study of nursing, which is premised on an interpersonal process between nurses and clients. Further, it is a useful style of research when there is little prior information about a topic. In this article (Part 1), Terence McCann and Eileen Clark outline the key features of this methodology. In the follow-up article (Part 2, McCann and Clark 2003a), a critique is provided of grounded theory and the two main approaches to this methodology. In the final article in the series (Part 3, McCann and Clark 2003b), the authors illustrate how grounded theory can be applied to nursing research with examples from McCann's Australian study (McCann and Baker 2001) of how community mental health nurses promote wellness with clients who are experiencing an early episode of psychotic illness.

    We introduce a general analytic approach to the study of factorization points and factorized ground states in quantum cooperative systems. The method allows us to determine rigorously the existence, location, and exact form of separable ground states in a large variety of, generally nonexactly solvable, spin models belonging to different universality classes. The theory applies to translationally invariant systems, irrespective of spatial dimensionality, and for spin-spin interactions of arbitrary range.

    2013-01-01

    Background Patient-centered care ideally considers patient preferences, values and needs. However, it is unclear if policies such as wait time strategies for hip and knee replacement surgery (TJR) are patient-centred as they focus on an isolated episode of care. This paper describes the accounts of people scheduled to undergo TJR, focusing on their experience of (OA) as a chronic disease that has considerable impact on their everyday lives. Methods Semi-structured qualitative interviews were conducted with participants scheduled to undergo TJR who were recruited from the practices of two orthopaedic surgeons. We first used maximum variation and then theoretical sampling based on age, sex and joint replaced. 33 participants (age 38-79 years; 17 female) were included in the analysis. 20 were scheduled for hip replacement and 13 for knee replacement. A constructivist approach to grounded theory guided sampling, data collection and analysis. Results While a specific hip or knee was the target for surgery, individuals experienced multiple-joint symptoms and comorbidities. Management of their health and daily lives was impacted by these combined experiences. Over time, they struggled to manage symptoms with varying degrees of access to and acceptance of pain medication, which was a source of constant concern. This was a multi-faceted issue with physicians reluctant to prescribe and many patients reluctant to take prescription pain medications due to their side effects. Conclusions For patients, TJR surgery is an acute intervention in the experience of chronic disease, OA and other comorbidities. While policy has focused on wait time as patient/surgeon decision for surgery to surgery date, the patient’s experience does not begin or end with surgery as they struggle to manage their pain. Our findings suggest that further work is needed to align the medical treatment of OA with the current policy emphasis on patient-centeredness. Patient-centred care may require a

    2016-01-01

    Background: Patients with cardiovascular-related chronic diseases may face financial barriers to accessing health care, even in Canada, where universal health care insurance is in place. No current theory or framework is adequate for understanding the impact of financial barriers to care on these patients or how they experience financial barriers. The overall objective of this study is to develop a framework for understanding the role of financial barriers to care in the lives of patients with cardiovascular-related chronic diseases and the impact of such barriers on their health. Methods: We will perform an inductive qualitative grounded theory study to develop a framework to understand the effect of financial barriers to care on patients with cardiovascular-related chronic diseases. We will use semistructured interviews (face-to-face and telephone) with a purposive sample of adult patients from Alberta with at least 1 of hypertension, diabetes, heart disease or stroke. We will analyze interview transcripts in triplicate using grounded theory coding techniques, including open, focused and axial coding, following the principle of constant comparison. Interviews and analysis will be done iteratively to theoretical saturation. Member checking will be used to enhance rigour. Interpretation: A comprehensive framework for understanding financial barriers to accessing health care is instrumental for both researchers and clinicians who care for patients with chronic diseases. Such a framework would enable a better understanding of patient behaviour and nonadherence to recommended medical therapies and lifestyle modifications. PMID:27398378

Data from interviews with 15 women with 3.25 or better grade point averages indicated that current academic achievement in their college SEM fields can be attributed to previous academic success, self awareness, time management and organizational skills, and maintaining a strong support network. Participants were motivated by an internal drive to academically succeed and attend graduate school. Recommendations are provided for professors, advisors, and student affairs professionals.

  14. Adjusting team involvement: a grounded theory study of challenges in utilizing a surgical safety checklist as experienced by nurses in the operating room

    2012-01-01

    Background Even though the use of perioperative checklists have resulted in significant reduction in postoperative mortality and morbidity, as well as improvements of important information communication, the utilization of checklists seems to vary, and perceived barriers are likely to influence compliance. In this grounded theory study we aimed to explore the challenges and strategies of performing the WHO’s Safe Surgical Checklist as experienced by the nurses appointed as checklist coordinators. Methods Grounded theory was used in gathering and analyzing data from observations of the checklist used in the operating room, in conjunction with single and focus group interviews. A purposeful sample of 14 nurse-anesthetists and operating room nurses as surgical team members in a tertiary teaching hospital participated in the study. Results The nurses’ main concern regarding checklist utilization was identified as “how to obtain professional and social acceptance within the team”. The emergent grounded theory of “adjusting team involvement” consisted of three strategies; distancing, moderating and engaging team involvement. The use of these strategies explains how they resolved their challenges. Each strategy had corresponding conditions and consequences, determining checklist compliance, and how the checklist was used. Conclusion Even though nurses seem to have a loyal attitude towards the WHO’s checklist regarding their task work, they adjusted their surgical team involvement according to practical, social and professional conditions in their work environment. This might have resulted in the incomplete use of the checklist and therefore a low compliance rate. Findings also emphasized the importance of: a) management support when implementing WHO’s Safe Surgical Checklist, and b) interprofessional education approach to local adaptation of the checklists use.

    2012-01-01

    Background: Clinical learning is one of the important issues that helps the perception of nursing students’ practice in a clinical setting and its effect on their professional development. The aim of this study is to describe and state the manner of clinical learning in nursing students. Materials and Methods: This qualitative study was conducted as a grounded theory. The individual semi-structured interviews and participants’ observations were taken into account with a purposive and theoretical sample of 27 participants. The data were analyzed using the grounded theory approach and the constant comparison analysis method. Results: The results showed that students use two approaches of Micro- and Macrolearning. The first includes learning conditions and situations that act like a foundation for the second one (Macrolearning). Macrolearning is a continuous process including all categories of “Facing unfavorable clinical facts”, “Clinical situation and appropriate decision making”, “Bridging the gap between practice and theory”, “Struggle for clinical independence”, and “Dynamism” in a continuum reflecting the struggle to obtain clinical competency (core variable). Conclusions: Through provision of such conditions as students’ gradual acquaintance with real situations, selection of more resistant students, use of mentorship and preceptor ship in clinical learning, enhancement of educational standards in hospitals, handling collaborative learning methods to make a cooperation spirit in internship environment, and so on, students can be helped to obtain clinical competency.

    Objective In approaching the study and practice of heart failure (HF) management, authors recognise that the patient–doctor relationship has a central role in engaging patients in their care. This study aims at identifying the features and the levers of HF patient engagement and suggestions for orienting clinical encounters. Design Using a grounded theory approach, we conducted 22 in-depth interviews (13 patients with HF, 5 physicians and 4 caregivers). Data were collected and analysed using open, axial and selective coding procedures according to the grounded theory principles. Settings All interviews were conducted in an office in a university hospital located in a metropolitan area of Milan, Italy. Participants The data comprised a total of 22 patient, hospital cardiologist and caregiver interviews. Patients aged ≥18 years with New York Heart Association (NYHA) Functional Class of II or III were eligible to take part. Patients were recruited primarily through their referral cardiologist. Results The HF patient engagement process develops in four main phases that are characterised by different patients’ emotional, cognitive and behavioural dynamics that contribute to shape the process of a patient's meaning making towards health and illness regarding their care. The emerging model illustrates that HF patient engagement entails a meaning-making process enacted by the patient after the critical event. This implies patients’ ability to give sense to their care experience and to their disease, symptomatology and treatments, and their changes along their illness course. Doctors are recognised as crucial in fostering patients’ engagement along all the phases of the process as they contribute to providing patients with self-continuity and give new meaning to their illness experience. Conclusions This study identifies the core experiential domains and the main levers involved in driving patients with HF to effectively engage in their disease management. The

    2011-01-01

    Many references to time or temporality are located within music therapy literature, however little research has been completed regarding this phenomenon. Findings from a modified grounded theory study about clients' experiences and descriptions of time within the context of music therapy are presented here. The study was informed by the constructivist-interpretive paradigm and a grounded-descriptive statement finding resulted. A 2-staged research methodology was used, comprising a deductive-inductive content analysis of information from the public domain, followed by data-mining of information from a minimum of 160 clients and analysis of data from at least 43 of these 160 clients. Information regarding memory experiences, the duration of music therapy effects, recall and retrieval, and experiences of time are identified. Implications for practice are emphasized, in particular the following is stressed (a) the importance of time orientation and temporal connectedness in relation to identity development, (b) temporal strategies within music experience to assist integration, recall, and retrieval of information, and (c) the importance of and the elements involved in time modification. New explanations for music therapy phenomena are shared, and areas for research highlighted. Benefits of using time dynamically to aid therapeutic process are proposed, and it is concluded that temporal experience within the context of music therapy is important in relation to both practice and research.

    2015-01-01

    Dengue fever, a mosquito-borne virus, is an ongoing public health issue in North Queensland. Importation of dengue fever by travellers visiting or returning to Australia can lead to epidemics. The mosquito can acquire the virus in the symptomatic viraemic phase, so timely recognition of cases is important to prevent epidemics. There is a gap in the literature about backpackers' knowledge of dengue fever and the decision-making process they use when considering utilising the Australian health-care system. This study uses grounded theory methods to construct a theory that explains the process backpackers use when seeking health care. Fifty semi-structured interviews with backpackers, hostel receptionists, travel agents and pharmacists were analysed, resulting in identification of a core category: 'weighing up the costs of seeking health care'. This core category has three subcategories: 'self-assessment of health status', 'wait-and-see' and 'seek direction'. Findings from this study identified key areas where health promotion material and increased access to health-care professionals could reduce the risk of backpackers spreading dengue fever.

    2014-02-01

    How practitioners conceive clinical practice influences many aspects of their clinical work including how they view knowledge, clinical decision-making, and their actions. Osteopaths have relied upon the philosophical and theoretical foundations upon which the profession was built to guide clinical practice. However, it is currently unknown how osteopaths conceive clinical practice, and how these conceptions develop and influence their clinical work. This paper reports the conceptions of practice of experienced osteopaths in the UK. A constructivist grounded theory approach was taken in this study. The constant comparative method of analysis was used to code and analyse data. Purposive sampling was employed to initially select participants. Subsequent theoretical sampling, informed by data analysis, allowed specific participants to be sampled. Data collection methods involved semi-structured interviews and non-participant observation of practitioners during a patient appointment, which was video-recorded and followed by a video-prompted reflective interview. Participants' conception of practice lay on a continuum, from technical rationality to professional artistry and the development of which was influenced by their educational experience, view of health and disease, epistemology of practice knowledge, theory-practice relationship and their perceived therapeutic role. The findings from this study provide the first theoretical insight of osteopaths' conceptions of clinical practice and the factors which influence such conceptions.

  5. Empowerment in school nursing practice: a grounded theory approach.

    PubMed

    Broussard, Lisa

    2007-12-01

    Professional empowerment is vital to nurses' productivity and job satisfaction. A grounded theory study was conducted to describe the basic social process experienced by school nurses in relation to professional empowerment. Interviews with 10 school nurses led to the development of a situation-specific theory of school nurse empowerment, Making a Difference: The Role of the School Nurse in the Health of Children in Schools. This theory was derived from four theoretical constructs: (a) enlisting support, (b) getting through the day, (c) maintaining control over practice, and (d) adjusting to challenges. Interviews revealed that knowing at the end of each school day that they made a difference in the health of children resulted in feelings of empowerment. Participants cited various areas in which their sense of empowerment was limited, including salaries and workload. Despite these issues, they believed they had a positive impact on the health of children, leading to job satisfaction and feelings of value.

    PubMed

    Ball, Lisa Sherry

    2013-11-30

    Accelerated nursing students are ideal informants regarding abstract nursing concepts. How emotional intelligence (EI) is used in nursing remains a relatively elusive process that has yet to be empirically modeled. The purpose of this study was to generate a theoretical model that explains how EI is used in nursing by accelerated baccalaureate nursing students. Using a mixed methods grounded theory study design, theoretical sampling of EI scores directed sampling for individual interviews and focus groups. Caring for a human being emerged as the basic social process at the heart of which all other processes--Getting it; Being caring; The essence of professional nurse caring; Doing something to make someone feel better; and Dealing with difficulty--are interconnected. In addition to a theoretical explanation of the use of EI in nursing, this study corroborates findings from other qualitative studies in nursing and contributes a rich description of accelerated baccalaureate nursing students and an example of a mixed methods study design to the small but growing literature in these areas.

    A simulation was conducted to examine the effect of shared air/ground authority when each is equipped with enhanced traffic- and conflict-alerting systems. The potential benefits of an advanced air traffic management (ATM) concept referred to as "free flight" include improved safety through enhanced conflict detection and resolution capabilities, increased flight-operations management, and better decision-making tools for air traffic controllers and flight crews. One element of the free-flight concept suggests shifting aircraft separation responsibility from air traffic controllers to flight crews, thereby creating an environment with "shared-separation" authority.

  13. Teaching Theory Construction With Initial Grounded Theory Tools: A Reflection on Lessons and Learning.

    PubMed

    Charmaz, Kathy

    2015-12-01

    This article addresses criticisms of qualitative research for spawning studies that lack analytic development and theoretical import. It focuses on teaching initial grounded theory tools while interviewing, coding, and writing memos for the purpose of scaling up the analytic level of students' research and advancing theory construction. Adopting these tools can improve teaching qualitative methods at all levels although doctoral education is emphasized here. What teachers cover in qualitative methods courses matters. The pedagogy presented here requires a supportive environment and relies on demonstration, collective participation, measured tasks, progressive analytic complexity, and accountability. Lessons learned from using initial grounded theory tools are exemplified in a doctoral student's coding and memo-writing excerpts that demonstrate progressive analytic development. The conclusion calls for increasing the number and depth of qualitative methods courses and for creating a cadre of expert qualitative methodologists.

    Lima, A. F.; Lalic, M. V.

    2016-10-01

    With objective to determine ground state magnetic structure of multiferroic hexagonal YMnO3 we performed systematic non-collinear spin density-functional-theory (DFT) study of six possible magnetic configurations of Mn ions, treating exchange and correlation effects by standard local-spin-density approximation (LSDA), by LSDA including Hubbard correction (LSDA+U), and taking into account the spin-orbit interaction. We found that P63 and P6´3 configurations are the most stable ones, with very small energy difference between them. This result substantiates conclusions of latest neutron-diffraction studies. Both configurations are characterized by canting of Mn spins that produces weak ferro- (P63) or anti-ferromagnetism (P6‧3) along the hexagonal c-axis. The calculated Mn magnetic moments are found to be in good agreement with experiment, and electronic structure generally agrees with previous non-collinear spin DFT studies that used different basis sets and exchange and correlation functionals.

    Type 2 diabetes is on the increase among the Swiss immigrants. The cultural background of patients presents new linguistic and sociocultural barriers and gains in importance for health care. In order to develop patient-centred care, it is necessary to focus on different sociocultural aspects in everyday life and experiences of immigrants from the former republics of Yugoslavia with diabetes who have rarely been studied in Switzerland. Based on these insights the needs for counselling can be identified and nursing interventions can be designed accordingly. Using the Grounded Theory approach, 5 interviews were analysed according to the Corbin and Strauss coding paradigm. The central phenomenon found is the experience to live in 2 different cultures. The complexity arises from the tension living in 2 cultural backgrounds at the same time. It turns out that in the country of origin the immigrants adjust their disease management. The changing daily rhythm and the more traditional role model affect aspects of their disease management such as diet and/or drug therapy. The different strategies impact the person's roles, emotions, their everyday lives and their families. It provides an insight into the perspective of Swiss immigrants from the former republics of Yugoslavia suffering from diabetes. Many questions are still unanswered and further research will be required.

    In order to calculate the ground movement induced by displacement piles driven into horizontal layered strata, an axisymmetric model was built and then the vertical and horizontal ground movement functions were deduced using stochastic medium theory. Results show that the vertical ground movement obeys normal distribution function, while the horizontal ground movement is an exponential function. Utilizing field measured data, parameters of these functions can be obtained by back analysis, and an example was employed to verify this model. Result shows that stochastic medium theory is suitable for calculating the ground movement in pile driving, and there is no need to consider the constitutive model of soil or contact between pile and soil. This method is applicable in practice. PMID:24701184

  19. A grounded theory of abstraction in artificial intelligence.

    PubMed Central

    Zucker, Jean-Daniel

    2003-01-01

    In artificial intelligence, abstraction is commonly used to account for the use of various levels of details in a given representation language or the ability to change from one level to another while preserving useful properties. Abstraction has been mainly studied in problem solving, theorem proving, knowledge representation (in particular for spatial and temporal reasoning) and machine learning. In such contexts, abstraction is defined as a mapping between formalisms that reduces the computational complexity of the task at stake. By analysing the notion of abstraction from an information quantity point of view, we pinpoint the differences and the complementary role of reformulation and abstraction in any representation change. We contribute to extending the existing semantic theories of abstraction to be grounded on perception, where the notion of information quantity is easier to characterize formally. In the author's view, abstraction is best represented using abstraction operators, as they provide semantics for classifying different abstractions and support the automation of representation changes. The usefulness of a grounded theory of abstraction in the cartography domain is illustrated. Finally, the importance of explicitly representing abstraction for designing more autonomous and adaptive systems is discussed. PMID:12903672

  20. Qualitative research in healthcare: an introduction to grounded theory using thematic analysis.

    Chapman, A L; Hadfield, M; Chapman, C J

    2015-01-01

    In today's NHS, qualitative research is increasingly important as a method of assessing and improving quality of care. Grounded theory has developed as an analytical approach to qualitative data over the last 40 years. It is primarily an inductive process whereby theoretical insights are generated from data, in contrast to deductive research where theoretical hypotheses are tested via data collection. Grounded theory has been one of the main contributors to the acceptance of qualitative methods in a wide range of applied social sciences. The influence of grounded theory as an approach is, in part, based on its provision of an explicit framework for analysis and theory generation. Furthermore the stress upon grounding research in the reality of participants has also given it credence in healthcare research. As with all analytical approaches, grounded theory has drawbacks and limitations. It is important to have an understanding of these in order to assess the applicability of this approach to healthcare research. In this review we outline the principles of grounded theory, and focus on thematic analysis as the analytical approach used most frequently in grounded theory studies, with the aim of providing clinicians with the skills to critically review studies using this methodology.

  1. Exploring the role of cognitive and structural forms of social capital in HIV/AIDS trends in the Kagera region of Tanzania - a grounded theory study.

    2011-04-01

    The article presents a synthesis of data from three village case studies focusing on how structural and cognitive social capital may have influenced the progression of the HIV epidemic in the Kagera region of Tanzania. Grounded theory was used to develop a theoretical model describing the possible links between structural and cognitive social capital and the impact on sexual health behaviours. Focus group discussions and key informant interviews were carried out to represent the range of experiences of existing social capital. Both structural and cognitive social capital were active avenues for community members to come together, empower each other, and develop norms, values, trust and reciprocal relations. This empowerment created an enabling environment in which members could adopt protective behaviours against HIV infection. On the one hand, we observed that involvement in formal and informal organisations resulted in a reduction of numbers of sexual partners, led people to demand abstinence from sexual relations until marriage, caused fewer opportunities for casual sex, and gave individuals the agency to demand the use of condoms. On the other hand, strict membership rules and regulations excluded some members, particularly excessive alcohol drinkers and debtors, from becoming members of the social groups, which increased their vulnerability in terms of exposure to HIV. Social gatherings (especially those organised during the night) were also found to increase youths' risk of HIV infection through instances of unsafe sex. We conclude that even though social capital may at times have negative effects on individuals' HIV-prevention efforts, this study provides initial evidence that social capital is largely protective through empowering vulnerable groups such as women and the poor to protect against HIV infection and by promoting protective sexual behaviours.

    Purpose To explore the perspectives of male clients in a neurological rehabilitation setting with regard to the occupational therapy they have received and the client-centred approach. Method This study involved a qualitative research design based on the grounded theory tradition. Individual in-depth interviews were used to collect data. Data were analysed using a constant comparative method. Seven male participants from an inpatient neurological setting were included using a theoretical sampling technique. Results Three themes emerged to describe the approach of the therapists to client-centred practice: (a) a shared biomedical focus as the start of the rehabilitation process, (b) the un-simultaneous shift from a biomedical towards a psycho-social focus and (c) formal versus informal nature of gathering client information. Conclusion A client-centred approach entails a shift from the therapist focussing on recovery from the short-term neurological issues towards the long-term consequences of the disease. According to the client, this shift in reasoning must occur at a specific and highly subjective moment during the rehabilitation process. Identifying this moment could strengthen the client-centred approach. Implications for Rehabilitation Client-centred practice entails a shift from recovering the short-term neurological issues towards the long-term psycho-social consequences of the disease. To be effective in client-centred practice, the clients expect from the professional to be an authority with regard to biomedical issues and to be partner with regard to psycho-social issues. Client-centred practice is most likely to be successful when client is susceptible to discuss his psycho-social issues and finding this moment is a challenge for the professional. Using formal methods for goal setting do not necessarily cover all the information needed for a client-centred therapy programme. Rather, using informal methods could lead to a more valid image of the client.

    2016-03-01

    Surveys among psychotherapists tend to show a high preference for integrationism/eclecticism. There is, however, a lack of empirical studies exploring the process by which these psychotherapists arrive at this orientation. To answer this question, 22 autobiographies published by integrative psychotherapists were analyzed using grounded theory analytic procedures. The analysis resulted in a 3-stage developmental model, consisting of (a) the Adherence Phase, (b) the Destabilization Phase, and (c) the Consolidation Phase. The results are discussed in relation to several speculative models of psychotherapist development toward integration, as well as empirical literature on psychotherapist development. The results suggest that the tendency toward integration is best regarded as a natural part of the process of psychotherapist development. PMID:26785357

  7. Ensemble Theory for Stealthy Hyperuniform Disordered Ground States

    NASA Astrophysics Data System (ADS)

    Torquato, Salvatore

    Disordered hyperuniform many-particle systems have been receiving recent attention because they are distinguishable exotic states of matter poised between a crystal and liquid that are endowed with novel thermodynamic and physical properties. It has been shown numerically that systems of particles interacting with ``stealthy'' bounded, long-ranged pair potentials (similar to Friedel oscillations) have classical ground states that are, counterintuitively, disordered, hyperuniform and highly degenerate. The task of formulating an ensemble theory that yields analytical predictions for the structural characteristics and other properties of stealthy degenerate ground states in d-dimensional Euclidean space is highly nontrivial because the dimensionality of the configuration space depends on the number density and there is a multitude of ways of sampling the ground-state manifold, each with its own probability measure for finding a particular ground-state configuration. A new type of statistical-mechanical theory had to be invented to characterize these exotic states of matter. I report on some initial progress that we have made in this direction. We show that stealthy disordered ground states behave like ''pseudo''-equilibrium hard-sphere systems in Fourier space. Our theoretical predictions for the structure and thermodynamic properties of the stealthy disordered ground states and associated excited states are in excellent agreement with computer simulations across dimensions.

  10. Health-care encounters create both discontinuity and continuity in daily life when living with chronic heart failure—A grounded theory study

    PubMed Central

    Östman, Malin; Ung, Eva Jakobsson; Falk, Kristin

    2015-01-01

    Living with chronic heart failure (CHF) often involves lifelong contact with health care, more or less frequently, depending on fluctuating health-generating disruptions in everyday life. To reduce the influence on continuity in life, health-care professionals should preferably focus on supporting patients in managing their daily lives, based on their perspective. The aim of this study was to describe how the interaction in health-care encounters contributes to either continuity or discontinuity in the daily life for persons with CHF. Interviews with 18 participants were carried out, using the grounded theory method, through data collection and analysis. Two core concepts were constructed from data which reveal a model that illuminates the characteristics of the encounters, the actions of health-care professionals and the normative discourse. Patient-centred agenda consists of the categories: “Experiencing a subordinate approach,” “Objectifying during the encounter” and “Expected to be compliant.” This describes how health-care professionals enhance discontinuity in daily life by using a paternalistic approach in the encounter. Person-centred agenda consists of the categories: “Experiencing an empowering approach,” “Person-centredness during the encounter” and “Expected to be capable.” It describes how participants perceive that health-care professionals enable them to deal with everyday life which enhances continuity. The findings highlight the importance of health-care professionals’ attitudes and communication in encounters with patients. Health care must be designed to support and promote patients’ own strategic thinking by strengthening their self-image to enhance continuity in everyday life. The experience of discontinuity is based on the prevailing health-care culture which focuses on disease and medical treatment and regards it as superior to the illness experience in an everyday life context. We therefore strongly suggest a

  12. No theory of justice can ground health care reform.

    PubMed

    Trotter, Griffin

    2012-01-01

    This essay argues that no theory or single conception of justice can provide a fundamental grounding for health care reform in the United States. To provide such a grounding, (1) there would need to be widespread support among citizens for a particular conception of justice, (2) citizens would have to apprehend this common conception of justice as providing the strongest available rationale for health care reform, and (3) this rationale would have to overwhelm countervailing values. I argue that neither of the first two conditions is met.

  13. Evolving Grounded Theory Methodology: towards a discursive approach.

    PubMed

    McCreaddie, May; Payne, Sheila

    2010-06-01

    Grounded Theory Methodology (GTM) is a widely cited research approach based upon symbolic interaction with a focus on interaction, action and processes. Relatively recently, Discursive Psychology; a language-based interaction research approach also based on symbolic interaction, emerged. At present Discursive Psychology is principally cited in the social sciences literature. Given Discursive Psychology's symbolic interaction foundations, what relevance does this approach have for evolving GTM? A number of methodological challenges were posed by a study looking at humour in Clinical Nurse Specialist-patient interactions. This paper will use the phenomenon of spontaneous humour in healthcare interactions to illustrate the potential for a new form of GTM drawing on discursive approaches; Discursive GTM. First, the challenges presented by a study looking at spontaneous humour in Clinical Nurse Specialist-patient interactions are presented. Second, the research approach adopted to meet these challenges - Discursive GTM (DGTM) - is explicated and the results of the study are outlined. Third, the different GTM approaches and Discursive Psychology are compared and contrasted in relation to the DGTM approach adopted. Finally, the challenges and tensions of using DGTM as well as the opportunities afforded by the use of naturally occurring data are reviewed. The authors contend that a DGTM approach may be appropriate in analyzing certain phenomena. In particular, we highlight the potential contribution of naturally occurring data as an adjunct to researcher-elicited data. Thus, when exploring particular phenomena, a DGTM approach may address the potentially under-developed symbolic interaction tenet of language.

  14. Gambler Risk Perception: A Mental Model and Grounded Theory Analysis.

    Spurrier, Michael; Blaszczynski, Alexander; Rhodes, Paul

    2015-09-01

    Few studies have investigated how gamblers perceive risk or the role of risk perception in disordered gambling. The purpose of the current study therefore was to obtain data on lay gamblers' beliefs on these variables and their effects on decision-making, behaviour, and disordered gambling aetiology. Fifteen regular lay gamblers (non-problem/low risk, moderate risk and problem gamblers) completed a semi-structured interview following mental models and grounded theory methodologies. Gambler interview data was compared to an expert 'map' of risk-perception, to identify comparative gaps or differences associated with harmful or safe gambling. Systematic overlapping processes of data gathering and analysis were used to iteratively extend, saturate, test for exception, and verify concepts and themes emerging from the data. The preliminary findings suggested that gambler accounts supported the presence of expert conceptual constructs, and to some degree the role of risk perception in protecting against or increasing vulnerability to harm and disordered gambling. Gambler accounts of causality, meaning, motivation, and strategy were highly idiosyncratic, and often contained content inconsistent with measures of disordered gambling. Disordered gambling appears heavily influenced by relative underestimation of risk and overvaluation of gambling, based on explicit and implicit analysis, and deliberate, innate, contextual, and learned processing evaluations and biases.

    The opening of a new medical school is a cause for celebration. Starting with a clean slate often gives the opportunity to adopt more modern teaching practices. However, encouraging large numbers of clinicians to start teaching and to adopt these new methods brings its own set of challenges. During the expansion phase of a new medical school, it was often noted that new teachers seemed to have considerable difficulties, and often expressed these as negativity towards student placements. This did not chime with much of the work from established schools, which seemed to evaluate expansion of teaching more positively. We wanted to better understand the issues involved. Semi-structured interviews were conducted involving GPs who had received medical students over the first four years of a newly established medical school. The aims were to assess the impact of the students on the new teachers, and to try to better understand why some teachers were experiencing difficulties. We collected qualitative and quantitative data at the interviews. The qualitative data were analysed using grounded theory which aims to link emerging themes together. The findings suggest that as the quantity of teaching medical students increases, the enjoyment and commitment to teaching may decrease. Concerns over the administration of teaching may begin to predominate. Two factors may help to reduce this: 1 Adequate investment in manpower and premises to reduce time and space constraints on teaching. 2 Practices considering themselves as teaching practices where education is a part of the practice identity.

    Background Grounded theory (GT) is founded on the premise that underlying social patterns can be discovered and conceptualised into theories. The method and need for theoretical sensitivity are best understood in the historical context in which GT was developed. Theoretical sensitivity entails entering the field with no preconceptions, so as to remain open to the data and the emerging theory. Investigators also read literature from other fields to understand various ways to construct theories. Aim To explore the concept of theoretical sensitivity from a classical GT perspective, and discuss the ontological and epistemological foundations of GT. Discussion Difficulties in remaining theoretically sensitive throughout research are discussed and illustrated with examples. Emergence - the idea that theory and substance will emerge from the process of comparing data - and staying open to the data are emphasised. Conclusion Understanding theoretical sensitivity as an underlying guiding principle of GT helps the researcher make sense of important concepts, such as delaying the literature review, emergence and the constant comparative method (simultaneous collection, coding and analysis of data). Implications for practice Theoretical sensitivity and adherence to the GT research method allow researchers to discover theories that can bridge the gap between theory and practice. PMID:27641705

Disordered hyperuniform systems have received attention recently because they are distinguishable exotic states of matter poised between a crystal and liquid that are endowed with novel thermodynamic and physical properties. The task of formulating an ensemble theory that yields analytical predictions for the structural characteristics and other properties of stealthy degenerate ground states in d -dimensional Euclidean space Rd is highly nontrivial because the dimensionality of the configuration space depends on the number density ρ and there is a multitude of ways of sampling the ground-state manifold, each with its own probability measure for finding a particular ground-state configuration. The purpose of this paper is to take some initial steps in this direction. Specifically, we derive general exact relations for thermodynamic properties (energy, pressure, and isothermal compressibility) that apply to any ground-state ensemble as a function of ρ in any d , and we show how disordered degenerate ground states arise as part of the ground-state manifold. We also derive exact integral conditions that both the pair correlation function g2(r ) and structure factor S (k ) must obey for any d . We then specialize our results to the canonical ensemble (in the zero-temperature limit) by exploiting an ansatz that stealthy states behave remarkably like "pseudo"-equilibrium hard-sphere systems in Fourier space. Our theoretical predictions for g2(r ) and S (k ) are in excellent agreement with computer simulations across the first three space dimensions. These results are used to obtain order metrics, local number variance, and nearest-neighbor functions across dimensions. We also derive accurate analytical

    The correct description of charge transfer in ground and excited states is very important for molecular interactions, photochemistry, electrochemistry, and charge transport, but it is very challenging for Kohn-Sham (KS) density functional theory (DFT). KS-DFT exchange-correlation functionals without nonlocal exchange fail to describe both ground- and excited-state charge transfer properly. We have recently proposed a theory called multiconfiguration pair-density functional theory (MC-PDFT), which is based on a combination of multiconfiguration wave function theory with a new type of density functional called an on-top density functional. Here we have used MC-PDFT to study challenging ground- and excited-state charge-transfer processes by using on-top density functionals obtained by translating KS exchange-correlation functionals. For ground-state charge transfer, MC-PDFT performs better than either the PBE exchange-correlation functional or CASPT2 wave function theory. For excited-state charge transfer, MC-PDFT (unlike KS-DFT) shows qualitatively correct behavior at long-range with great improvement in predicted excitation energies.

    2013-07-01

    The experiences of vicarious unemployment (VU) among 17 undergraduate student participants who had a primary caregiver who was involuntarily unemployed were explored using grounded theory (Charmaz, 2006; Glaser & Strauss, 1967). Data from semistructured interviews with 15 women and 2 men revealed the nuanced nature of experiences with unemployment among those who experience it vicariously. Struggles related to increased family stress and experiences with stigma were common across participants. As participants reflected upon these challenges, they both lamented the costs associated with the struggles and expressed appreciation for the lessons that they have learned. They emerged from their VU experiences with increased financial and job market awareness, which informed their hope for a life that is free from the struggles endured in their families. Participants expressed confidence in their ability to cultivate financial security for their own families, stable employment, and opportunities to pursue work that will allow them to give back to others. Implications for counseling and directions for future research are discussed.

    This article uses grounded theory to explore the shared ideology espoused in Alcoholics Anonymous, specifically the nature and role of shared ideology in increasing the efficacy of the recovery process, and the features of the group's tenets and meetings that help facilitate members' indoctrination. Findings support Kassel and Wagner's (1993) contention of shared ideology's major role in the change process of the group, and Antze's (1976) categorizations of the AA ideology and alcoholics' characteristics. Antze's (1979) finding that AA ideology removes the concept of drinking from the voluntary sphere was also supported. The group was found to be a context in which members could change their assumptive worlds through reinterpreting life events, as Frank and Frank (1991) contended. Little support was found for Alexander and Rollins's (1984) comparison of AA to religious cults. The findings underscore the importance of human interaction as persuasion and reinforcement for AA ideology.

    Understanding slow and fast ground motion is important for the successful operation and design for present and future colliders. Since 2000 there have been several studies of ground motion at Fermilab. Several different types of HLS (hydro static level sensors) have been used to study slow ground motion (less than 1 hertz) seismometers have been used for fast (greater than 1 hertz) motions. Data have been taken at the surface and at locations 100 meters below the surface. Data of recent slow ground motion measurements with HLSs, many years of alignment data and results of the ATL-analysis are presented and discussed.

  16. The symbol-grounding problem in numerical cognition: A review of theory, evidence, and outstanding questions.

    2016-03-01

    How do numerical symbols, such as number words, acquire semantic meaning? This question, also referred to as the "symbol-grounding problem," is a central problem in the field of numerical cognition. Present theories suggest that symbols acquire their meaning by being mapped onto an approximate system for the nonsymbolic representation of number (Approximate Number System or ANS). In the present literature review, we first asked to which extent current behavioural and neuroimaging data support this theory, and second, to which extent the ANS, upon which symbolic numbers are assumed to be grounded, is numerical in nature. We conclude that (a) current evidence that has examined the association between the ANS and number symbols does not support the notion that number symbols are grounded in the ANS and (b) given the strong correlation between numerosity and continuous variables in nonsymbolic number processing tasks, it is next to impossible to measure the pure association between symbolic and nonsymbolic numerosity. Instead, it is clear that significant cognitive control resources are required to disambiguate numerical from continuous variables during nonsymbolic number processing. Thus, if there exists any mapping between the ANS and symbolic number, then this process of association must be mediated by cognitive control. Taken together, we suggest that studying the role of both cognitive control and continuous variables in numerosity comparison tasks will provide a more complete picture of the symbol-grounding problem.

  19. Studies in clustering theory

    NASA Astrophysics Data System (ADS)

    Stell, George

    In recent years the properties of percolation models have been studied intensively. The purpose of our project was to develop a general theory of percolation and clustering between particles of arbitrary size and shape, with arbitrary correlations between them. The goal of such a theory includes the treatment of continuum percolation as well as a novel treatment of lattice percolation. We made substantial progress toward this goal. The quantities basic to a description of clustering, the mean cluster size, mean number of clusters, etc., were developed. Concise formulas were given for the terms in such series, and proved, at least for sufficiently low densities, that the series are absolutely convergent. These series can now be used to construct Pade approximants that will allow one to probe the percolation transition. A scaled-particle theory of percolation was developed which gives analytic approximants for the mean number of clusters in a large class of two and three dimensional percolation models. Although this quantity is essential in many applications, e.g., explaining colligative properties, and interpreting low-angle light-scattering data, no systematic studies of it have been done before this work. Recently carried out detailed computer simulations show that the mean number of clusters is given to high accuracy by several of there approximations. Extensions of this work will allow calculation of the complete cluster size distribution.

We probe the transverse structure of the flux tube through the creation of non-uniform smearing profiles for the string of glue connecting two color sources in Wilson loop operator. The non-uniformly UV-regulated flux-tube operators are found to optimize the overlap with the ground state and display interesting features in the ground state overlap.

  1. The game of science: A grounded theory of the Cafe Scientifique experience

    NASA Astrophysics Data System (ADS)

    Rabe, Lisa A.

    Science Cafes are independent groups organized throughout the world for discussion of scientific topics. Little is known about the nature of this informal learning environment. A grounded-theory study was conducted to determine what attendees perceived as the essential qualities of the Cafe Scientifique experience in one science Cafe in the Western United States. Interviews with 12 attendees were transcribed and analyzed using ATLAS-ti. Concept maps and a grounded theory describing the essential characteristics were created. Member checking was used during theory generation. Findings are described in the context of a game metaphor, whereby scientific discussion at the Cafe is viewed as an intellectual game. The grounded theory describes the game of science being played at Cafe Scientifique involving attendees as players, social norms as rules for the game, an expert as the steward of truth, topics as the content for game play, interaction as playing of the game, and intellectual stimulation as the prize for playing. During the game, ideas were identified through a short presentation followed by a question-and-answer session. During this exchange, attendees heard about, analyzed, synthesized, and applied new information. As a result of the game play, players won a prize---intellectual stimulation. The Cafe Scientifique phenomenon provides insight into informal adult education. This study suggests the need for additional study of intellectual play in adult education, the role of curiosity and desire to explore new ways of thinking, and the developmental drive in adults to seek intellectual stimulation. The essential characteristics of Cafe Scientifique may be transferable to other informal adult-education settings.

    2009-06-01

    Qualitative theories of illness experience are about the individual interpretations of the psychosocial and cultural aspects of living with illness. Thus, they contribute to a better understanding of health and health care provision. In this paper, we examine how a grounded theory (GT) of heart disease experience can inform secondary prevention. In-depth interviews of individual experience of heart disease were conducted with 26 patients, using GT iterative data collection and analysis framework. A GT was compiled from data and examined within a sociocultural framework to ascertain how experience influenced health behaviour. Despite individual contextual variations, the theory of 'keeping it going' describes the study sample's common attitude to living with heart disease. The theory was adequate in explaining secondary cardiac behaviour, because it identified the aspects of patients' beliefs and attitudes which are key to effective secondary prevention. The assessment of the impact of illness experience on health behaviour within a sociocultural framework helped to articulate the strong influence of social and contextual factors. The study offers an appropriate explanatory framework for encouraging health behaviour change. It emphasizes the importance of interventions being relevant to individual perceptions and interpretations. It provides a framework for designing and evaluating cardiac interventions and the theoretical principles which underpin them.

    2002-01-01

    The aim of this study was to develop a model for how nursing personnel view oral health in general and the oral health of the care receivers in particular, applying a health promotion perspective and using grounded theory analysis. Data were collected through interviews with 17 nursing personnel, selected by strategic sampling. Analysis of the transcribed interviews showed that there were four strategies, related to staff education, hospital resources, and leadership motivation. The strategies were grounded in data and emerged from the interaction between the two main categories: 'the valuation of the importance of oral health' and 'the behavior towards oral health maintenance'. They were characterized as the routine, theoretical, practical, and flexible strategies, with the latter considered ideal. As increased knowledge is one important part in enhancing the nursing personnel's ability to perform oral hygiene procedures, there is a need for education among nursing personnel, primarily among those using a routine strategy.

    The purpose of this research was to study the way faculty establish course social presence in an online course. The community of inquiry model by Garrison, Anderson, and Archer distinguished the area of social presence as an important component of online learning, and this study sought to understand how faculty perceive and create social presence in their online classroom. By employing a grounded theory approach, a substantive theory was developed to explain the way in which faculty create and maintain an online course climate. The sample consisted of 10 nursing faculty teaching various master's in nursing courses. Through a rigorous qualitative process using nursing faculty interviews and online course analysis, humanization was found to be the core category in setting online course climate. Faculty's efforts to humanize the climate lead each member of the community to view the other members as real, thereby enabling the establishment of online social presence.

  8. A grounded theory: seeking relief from flatus as relevant client-nurse action and interaction.

    PubMed

    Annells, Merilyn

    2007-01-01

    Flatus problems are not uncommon among gastroenterological clients and those in other care settings. Yet what clients and nurses do productively about those problems in regard to their actions and interactions and why they do so has not previously been the focus of research. Holistic health management requires trustworthy qualitative evidence to guide best practice in this regard. This study systematically developed a substantive grounded theory that details and explains the trajectory of the basic social process: seeking relief from being discommoded (inconvenienced, troubled) by flatus in the situational context of client-nurse interactions. In the theory, there is also a focus on the context of nursing care situations, possible constraints, and likely outcomes. Grounded theory method was applied. Data were collected through semistructured individual interviews, nonparticipant observation, and document analysis regarding incidents and situations involving 38 participants-clients and registered nurses. The results show that clients, when trying to do something about the situation, can be severely discommoded by flatus problems and are hampered by embarrassment and the social taboo about admitting that one is bothered by flatus. The individual may or may not disclose the problem to a nurse, and nurses may or may not be attuned to these problems. There are ways for nurses to be helpful in these situations and possible remedies are identified in this article.

Our correction factors may be used for planar or nonplanar faults having any dip or slip rake (faulting mechanism). Our correction factors predict directivity-induced variations of spectral acceleration that are roughly half of the strike-slip variations predicted by Somerville et al. (1997), and use of our factors reduces record-to-record sigma by about 2-20% at 5 sec or greater period. ?? 2008, Earthquake Engineering Research Institute.

    The aim of this study is to understand how parents manage the risk of child sexual abuse, including prevention as well as early intervention and detection strategies. Using a social constructivist theoretical foundation and grounded theory methods, qualitative in-depth interviews were conducted with Australian parents between 2006 and 2008. Based on the data, a balance theory was developed, which explains how parents attempt to balance the type of information given to children in order to protect their children from sexual abuse without scaring them as well as how parents manage sexual boundary crossing incidents experienced by their children in the context of complex social relationships. Implications for prevention programs as well as reporting of child sexual abuse are discussed.

  11. CTE Teachers' Perspectives on the Process of CTE and Science Content Integration: A Grounded Theory

    NASA Astrophysics Data System (ADS)

    Spindler, Matthew Kenneth

    The integration of career and technical education (CTE) and academic curricular content that capitalizes on natural and inherent connections represents a challenge for CTE professionals. The research question that was used to guide the current study was: What are CTE teachers' perspectives of and experiences with the process of CTE and science content integration? And more specifically, to generate a grounded theory which explicates the process of CTE and science content integration from the perspective of CTE teachers. The CTE teachers expressed that the process of CTE and science content integration was a process of evolutionizing. From the perspective of the CTE teachers involved integrating CTE and science content resulted in their programs of study being adapted into something different than they were before the process of integration was begun. The CTE teachers revealed that the evolutions in their programs of study and themselves were associated with three other categories within the grounded theory: (a) connecting; (b) enacting; and (c) futuring. The process of CTE and science content integration represents a deep and complex episode for CTE teachers. The process of CTE and science content integration requires connecting to others, putting ideas into action, and an orienting towards the future.

  12. Experimental Studies about Transient Characteristics of a Deeply Buried Grounding Electrode and a Grounding Mesh

    NASA Astrophysics Data System (ADS)

    Yamamoto, Kazuo; Yanagawa, Shunichi; Sekioka, Shozo

    When lightning strikes the tower of a cellular phone base station or other such facilities, power and communication equipments in the vicinity of the tower may suffer extensive damages due to the lightning current flowing backward from the grounding system of the tower. The use of a deeply buried grounding electrode has been proposed recently to suppress such back flow current and a potential rise in the vicinity of the tower. The deeply buried grounding electrode is a bare conductor buried deep in the ground that is connected to a lightning rod on the ground by an insulated wire. When lightning strikes the lightning rod, the lightning current is directed to the electrode from which it diffuses to the ground. The deeply buried grounding electrodes have been installed in cellular phone base stations and other such facilities to solve such problems caused by the back flow current and the potential rise. A grounding mesh is usually laid around such base stations as a grounding system for the facilities on the ground. Therefore, it is important to understand the interactions between the deeply buried grounding electrode and the grounding mesh. In this study, experiments on the interactions between a grounding mesh and a deeply buried grounding electrode have been carried out. Additionally, the transient characteristics of the mesh grounding have researched.

  18. Ground State Studies of Spin Glass Models.

    NASA Astrophysics Data System (ADS)

    Kolan, Amy Joanne

    The ground state energy and degeneracy for a set of spin glass models, PQR models, has been studied in detail. For the pure frustration case, a subset of the general PQR case, we have studied the spacial distribution of frustrated plaquettes at T = 0. We investigated the "frustration -frustration" correlation function, which involved a series expansion analysis and a computer analysis, to examine a phase transition mechanism proposed by Schuster (1981). Schuster suggested that a pair of plaquettes is bound together above, and dissociated below a critical concentration of antiferromagnetic bonds. Our analysis, however, led us to conclude that there is no sharp "unbinding" of frustration pairs. We have developed an efficient algorithm to compute the ground state energy and degeneracy of sample PQR lattices and have studied the general PQR model numerically. Our algorithm is similar in essence to Morgenstern and Binder's (1980) transfer matrix approach used to calculate the partition function of a sample of spins in the pure frustration case. The algorithm involves computing times of order ALM 2('L), where L is the width of the lattice, M is the length, and A is a constant of proportionality. We have used the results of our analysis to investigate the possibility of a paramagnetic (<--->) spin glass phase transition in the PQR model at T = 0. Although scatter in our results for the ground state degeneracy/spin obscures evidence of a possible non-analyticity in this function, we do see evidence of a "break" in the curves for the ground state energy/spin. We have used this "break" to plot the phase transition line between the spin glass and paramagnetic regimes.

    2000-01-01

    Over the last 25 years, industry and government have made large financial investments aimed at improving water quality across the Nation. Significant progress has been made; however, many water-quality concerns remain. In 1991, the U.S. Geological Survey (USGS) began implementing a full-scale National Water-Quality Assessment Program to provide consistent and scientifically sound information for managing the Nation's water resources. The goals of the NAWQA Program are to (1) describe current water-quality conditions for a large part of the Nation's freshwater streams and aquifers, (2) describe how water quality is changing over time, and (3) improve our understanding of the primary natural and human factors affecting water quality. Assessing the quality of water in every location in the Nation would not be practical; therefore, NAWQA Program studies are conducted within a set of areas called study units (fig. 1). These study units are composed of more than 50 important river and aquifer systems that represent the diverse geography, water resources, and land and water uses of the Nation. The High Plains Regional Ground-Water Study is one such study area, designed to address issues relevant to the High Plains Aquifer system while supplementing water-quality information collected in other study units across the Nation. Implementation of the NAWQA Program for the High Plains Regional Ground-Water Study area began in 1998.

    Hussain, Zahid; Slany, Wolfgang; Holzinger, Andreas

    This paper investigates how the integration of agile methods and User-Centered Design (UCD) is carried out in practice. For this study, we have applied grounded theory as a suitable qualitative approach to determine what is happening in actual practice. The data was collected by semi-structured interviews with professionals who have already worked with an integrated agile UCD methodology. Further data was collected by observing these professionals in their working context, and by studying their documents, where possible. The emerging themes that the study found show that there is an increasing realization of the importance of usability in software development among agile team members. The requirements are emerging; and both low and high fidelity prototypes based usability tests are highly used in agile teams. There is an appreciation of each other's work from both UCD professionals and developers and both sides can learn from each other.

    Hoflund, A Bryce

    2013-01-01

    This paper describes how grounded theory was used to investigate the "black box" of network leadership in the creation of the National Quality Forum. Scholars are beginning to recognize the importance of network organizations and are in the embryonic stages of collecting and analyzing data about network leadership processes. Grounded theory, with its focus on deriving theory from empirical data, offers researchers a distinctive way of studying little-known phenomena and is therefore well suited to exploring network leadership processes. Specifically, this paper provides an overview of grounded theory, a discussion of the appropriateness of grounded theory to investigating network phenomena, a description of how the research was conducted, and a discussion of the limitations and lessons learned from using this approach.

  5. Development of three-dimensional state-space wake theory and application in dynamic ground effect

    NASA Astrophysics Data System (ADS)

    Yu, Ke

    In topics of rotorcraft wake analysis, state-space wake theory has a recognized reputation for advantages in real-time simulation, preliminary design and eigenvalue analysis. Developments in the past decades greatly improved range of validity and accuracy of the state-space modeling approach. This work focuses on further improvement of the state-space wake theory and applications in representing dynamic ground effect. Extended state-space model is developed to represent non-zero mass flux on rotor disk. Its instant practical application, representing ground effect with a mass source ground rotor, is evaluated in both steady and dynamic aspects. Investigations of partial ground effect simulation by state-space model are carried out in different rotor configurations. Additional work is done in improving simulation efficiency of practical application of state-space modeling.

    2015-08-01

    The tight bond between grounded theory (GT) and symbolic interactionism (SI) is well known within the qualitative health research field. We aimed to disentangle this connection through critical reflection on the conditions under which it might add value as an underpinning to studies outside the GT tradition. Drawing on an examination of the central tenets of SI, we illustrate with a field study using interpretive description as methodology how SI can be applied as a theoretical lens through which layers of socially constructed meaning can help surface the subjective world of patients. We demonstrate how SI can function as a powerful framework for human health behavior research through its capacity to orient questions, inform design options, and refine analytic directions. We conclude that using SI as a lens can serve as a translation mechanism in our quest to interpret the subjective world underlying patients' health and illness behavior.

    This study was aimed at understanding, from the nurses' perspective, the experience of going through the Systematization of nursing care (SNC) in an obstetric service unit. We used grounded theory as the theoretical and methodological framework. The subjects of this study consisted of thirteen nurses from a public hospital in the city of João Pessoa, in the state of Paraíba. The data analysis resulted in the following phenomenon. "perceiving SNC as a working method that organizes, directs and improves the quality of care by bringing visibility and providing security for the nursing staff" The nurses expressed the extent of knowledge about the SNC experienced in obstetrics as well as considered the nursing process as a decision-making process, which guides the reasoning of nurses in the planning of nursing care in obstetrics. It was concluded that nurses perceive the SNC as an instrument of theoretical-practical articulation leading to personalized assistance.

    Eriksson, Jeanette Källstrand; Hildingh, Cathrine; Buer, Nina; Thulesius, Hans

    2016-01-01

    The purpose of this classic grounded theory study was to understand how seniors who are living independently resolve issues influenced by visual impairment and high fall risk. We interviewed and observed 13 seniors with visual impairment in their homes. We also interviewed six visual instructors with experience from many hundreds of relevant incidents from the same group of seniors. We found that the seniors are resolving their main concern of "remaining themselves as who they used to be" by self-preservation. Within this category, the strategies maintaining the established self and defying deterioration emerged as the most prominent in our data. The theme maintaining the established self is mostly guided by change inertia and includes living the past (retaining past activities, reminiscing, and keeping the home intact) and facading (hiding impairment, leading to avoidance of becoming a burden and to risk juggling). Defying deterioration is a proactive scheme and involves moving (by exercising, adapting activities, using walking aids, driving), adapting (by finding new ways), and networking by sustaining old support networks or finding new networks. Self-preservation is generic human behavior and modifying this theory to other fields may therefore be worthwhile. In addition, health care providers may have use for the theory in fall preventive planning.

    2012-02-20

    Ground motion can cause significant deterioration in the luminosity of a linear collider. Vibration of numerous focusing magnets causes continuous misalignments, which makes the beam emittance grow. For this reason, understanding the seismic vibration of all potential LC sites is essential and related efforts in many sites are ongoing. In this document we summarize the results from the studies specific to Fermilab grounds as requested by the LC project leader at FNAL, Shekhar Mishra in FY04-FY06. The Northwestern group focused on how the ground motion effects vary with depth. Knowledge of depth dependence of the seismic activity is needed in order to decide how deep the LC tunnel should be at sites like Fermilab. The measurements were made in the NuMI tunnel, see Figure 1. We take advantage of the fact that from the beginning to the end of the tunnel there is a height difference of about 350 ft and that there are about five different types of dolomite layers. The support received allowed to pay for three months of salary of Michal Szleper. During this period he worked a 100% of his time in this project. That include one week of preparation: 2.5 months of data taking and data analysis during the full period of the project in order to guarantee that we were recording high quality data. We extended our previous work and made more systematic measurements, which included detailed studies on stability of the vibration amplitudes at different depths over long periods of time. As a consequence, a better control and more efficient averaging out of the daytime variation effects were possible, and a better study of other time dependences before the actual depth dependence was obtained. Those initial measurements were made at the surface and are summarized in Figure 2. All measurements are made with equipment that we already had (two broadband seismometers KS200 from GEOTECH and DL-24 portable data recorder). The offline data analysis took advantage of the full Fourier spectra

    Unusual sensory experiences are commonly seen in people with Asperger syndrome (AS). They correlate with functional impairments and cause distress. The current study investigates how these experiences have affected nine adults with AS's lives, as well as the coping strategies utilised. Semi-structured interviews were conducted using Instant Messaging software. Data were analysed using Grounded Theory. A number of inter-related categories and focused codes were identified. The categories included heightened senses, sensory stress, the stress avalanche, moderating factors, coping strategies, other people, self-acceptance, fascination, and isolation. A model was constructed as to how these categories and codes interact. How these findings link with previous research into autism spectrum disorders is discussed. Implications for services and future research are also made.

    1977-01-01

    Diagrammatic many-body perturbation theory is employed in a study of the ground state of the carbon monosulfide molecule for bond lengths close to the equilibrium value. The calculations are complete through third order in the energy within the algebraic approximation. Two different zero-order Hamiltonians are considered, and all two-, three-, and four-body terms are determined for the corresponding perturbation expansions. Many-body effects are found to be very important. Pade approximants to the energy expansion are constructed, and upper bounds evaluated. Almost 53 percent of the estimated correlation energy is recovered. The variation of components of the correlation energy with nuclear separation is investigated. Spectroscopic constants are also calculated.

  14. Managing uncertainty: a grounded theory of stigma in transgender health care encounters.

    PubMed

    Poteat, Tonia; German, Danielle; Kerrigan, Deanna

    2013-05-01

    A growing body of literature supports stigma and discrimination as fundamental causes of health disparities. Stigma and discrimination experienced by transgender people have been associated with increased risk for depression, suicide, and HIV. Transgender stigma and discrimination experienced in health care influence transgender people's health care access and utilization. Thus, understanding how stigma and discrimination manifest and function in health care encounters is critical to addressing health disparities for transgender people. A qualitative, grounded theory approach was taken to this study of stigma in health care interactions. Between January and July 2011, fifty-five transgender people and twelve medical providers participated in one-time in-depth interviews about stigma, discrimination, and health care interactions between providers and transgender patients. Due to the social and institutional stigma against transgender people, their care is excluded from medical training. Therefore, providers approach medical encounters with transgender patients with ambivalence and uncertainty. Transgender people anticipate that providers will not know how to meet their needs. This uncertainty and ambivalence in the medical encounter upsets the normal balance of power in provider-patient relationships. Interpersonal stigma functions to reinforce the power and authority of the medical provider during these interactions. Functional theories of stigma posit that we hold stigmatizing attitudes because they serve specific psychological functions. However, these theories ignore how hierarchies of power in social relationships serve to maintain and reinforce inequalities. The findings of this study suggest that interpersonal stigma also functions to reinforce medical power and authority in the face of provider uncertainty. Within functional theories of stigma, it is important to acknowledge the role of power and to understand how stigmatizing attitudes function to maintain

  15. Support Needs for Canadian Health Providers Responding to Disaster: New Insights from a Grounded Theory Approach

    PubMed Central

    Fahim, Christine; O'Sullivan, Tracey L.; Lane, Dan

    2015-01-01

    Introduction: An earlier descriptive study exploring the various supports available to Canadian health and social service providers who deployed to the 2010 earthquake disaster in Haiti, indicated that when systems are compromised, professionals are at physical, emotional and mental risk during overseas deployment. While these risks are generally well-identified, there is little literature that explores the effectiveness of the supports in place to mitigate this risk. This study provides evidence to inform policy development regarding future disaster relief, and the effectiveness of supports available to responders assisting with international disaster response. Methods: This study follows Strauss and Corbin’s 1990 structured approach to grounded theory to develop a framework for effective disaster support systems. N=21 interviews with Canadian health and social service providers, who deployed to Haiti in response to the 2010 earthquake, were conducted and analyzed. Resulting data were transcribed, coded and analysed for emergent themes. Results and Discussion: Three themes were identified in the data and were used to develop the evolving theory. The interview data indicate that the experiences of responders are determined based on an interaction between the individual’s ‘lens’ or personal expectations, as well as the supports that an organization is able to provide. Therefore, organizations should consider the following factors: experience, expectations, and supports, to tailor a successful support initiative that caters to the needs of the volunteer workforce.

    Aims and objectives The aim of this study was to generate a theory conceptualizing and explaining behavioural processes involved in coping in order to identify the predominant coping types and coping type-specific features. Background Patients undergoing fast track procedures do not experience a higher risk of complications, readmission, or mortality. However, such programmes presuppose an increasing degree of patient involvement, placing high educational, physical, and mental demands on the patients. There is a lack of knowledge about how patients understand and cope with fast track programmes. Design The study design used classical grounded theory. Methods The study used a multimodal approach with qualitative and quantitative data sets from 14 patients. Results Four predominant types of coping, with distinct physiological, cognitive, affective, and psychosocial features, existed among patients going through a fast track total hip replacement programme. These patients’ main concern was to restore their physical and psychosocial integrity, which had been compromised by reduced function and mobility in daily life. To restore integrity they economized their mental resources, while striving to fulfil the expectations of the fast track programme. This goal was achieved by being mentally proactive and physically active. Three out of the four predominant types of coping matched the expectations expressed in the fast track programme. The non-matching behaviour was seen among the most nervous patients, who claimed the right to diverge from the programme. Conclusion In theory, four predominant types of coping with distinct physiological, cognitive, affective, and psychosocial features occur among patients going through a fast track total hip arthroplasty programme.

    This study aimed to develop a grounded theory to describe and explain the experience of pain and its impact, as reported by the individuals who had pain associated with chronic leg ulceration. The Strauss and Corbin grounded theory approach was used. In-depth interviews were undertaken with 11 people aged ≥ 65 years from Leeds in the north of England. All participants were cared for by home care nurses and had painful leg ulceration. The emergent grounded theory centered on a core category of "The journey to chronic pain." The theory suggested a trajectory consisting of three phases that the patient experiences, where the end result is a chronic pain syndrome. In phase 1, leg ulcer pain has predominantly acute nociceptive properties, and if this is not managed effectively, or ulcers do not heal, persistent pain may develop with both nociceptive and neuropathic properties (i.e., phase 2). If phase 2 pain is not managed effectively, patients may then develop refractory long-term pain (phase 3). Those who progress to phase 3 tend to experience negative consequences such as insomnia, depression, and suicidal ideation. Only when health care professionals understand and acknowledge the persistent and long-term nature of the pain in this patient group can the pain be managed effectively.

    While bullying in the healthcare workplace has been recognized internationally, there is still a culture of silence in many institutions in the United States, perpetuating underreporting and insufficient and unproven interventions. The deliberate, repetitive, and aggressive behaviors of bullying can cause psychological and/or physical harm among professionals, disrupt nursing care, and threaten patient safety and quality outcomes. Much of the literature focuses on categories of bullying behaviors and nurse responses. This qualitative study reports on the experiences of nurses confronting workplace bullying. We collected data from the narratives of 99 nurses who completed an open-ended question embedded in an online survey in 2007. A constructivist grounded theory approach was used to analyze the data and shape a theory of how nurses make things right when confronted with bullying. In a four-step process, nurses place bullying in context, assess the situation, take action, and judge the outcomes of their actions. While many nurses do engage in a number of effective yet untested strategies, two additional concerns remain: inadequate support among nursing colleagues and silence and inaction by nurse administrators. Qualitative inquiry has the potential to guide researchers to a greater understanding of the complexities of bullying in the workplace. PMID:22567223

    This report covers progress to date under this grant on our continuing program to conduct ground based studies of the outer solar system planets and satellites, with emphasis on spectroscopy and atmospheric phenomena. The research continues under our new PAST grant, NNG04G131G beginning 5/1/2004. The original period of performance of the subject grant was 3/1/2001 to 2/28/2004, but was extended one year at no cost. Although there is some overlap in the scientific projects conducted during the extended year with those of the new grant, this report is confined to the portion of the work funded under NAG5-10435. The primary goals for this grant period were a comparative study of outer planet thermospheres/ionospheres near solar maximum, extended to the mid-IR, and the investigation of molecular dimers in outer solar system atmospheres. This project supports NASA's planned space missions, Jupiter Polar Orbiter, outer Planet Microprobes, and the recent Cassini flyby of Jupiter. It also supports the OSS strategic plan themes, The Exploration of the Solar System and The Sun-Earth Connection/ Understanding comparative planetary space environments.

    The objective of this study was to explore the perceptions of New Zealand secondary school nurses regarding skin infections in young people aged 14-18 years. A constructivist grounded theory method was adopted. Ten non-structured interviews were conducted with secondary school nurses working in Auckland, New Zealand, between January and July 2013. Interviews were audiotaped, transcribed and analysed using all tenets of grounded theory that included writing memos, theoretical sampling and the constant comparative method. Analysis revealed the core category Maintaining the balance, which is presented as a grounded theory model. It represents the constant state of balancing the school nurse undergoes in trying to counter the risk to the student. The nurse attempts to tip the balance in favour of action, by reducing barriers to healthcare, providing youth-friendly, affordable and accessible healthcare, and following up until resolution is achieved. The nurse is aware that failing to monitor until resolution can again tip the fulcrum back to inaction, placing the young person at risk again. It is concluded that nurses are knowledgeable about the risks present in the communities they serve and are innovative in the methods they employ to ensure satisfactory outcomes for young people experiencing skin infections. School nursing is an evolving model for delivering primary healthcare to young people in New Zealand. The grounded theory model 'Maintaining the balance' describes a model of care where nursing services are delivered where young people spend time, and the nurse is immersed in the community. This model of care may be transferable to other healthcare situations.

    Photogrammetric methods and analysis results for contrails observed with wide-angle cameras are described. Four cameras of two different types (view angle < 90° or whole-sky imager) at the ground at various positions are used to track contrails and to derive their altitude, width, and horizontal speed. Camera models for both types are described to derive the observation angles for given image coordinates and their inverse. The models are calibrated with sightings of the Sun, the Moon and a few bright stars. The methods are applied and tested in a case study. Four persistent contrails crossing each other together with a short-lived one are observed with the cameras. Vertical and horizontal positions of the contrails are determined from the camera images to an accuracy of better than 200 m and horizontal speed to 0.2 m s-1. With this information, the aircraft causing the contrails are identified by comparison to traffic waypoint data. The observations are compared with synthetic camera pictures of contrails simulated with the contrail prediction model CoCiP, a Lagrangian model using air traffic movement data and numerical weather prediction (NWP) data as input. The results provide tests for the NWP and contrail models. The cameras show spreading and thickening contrails suggesting ice-supersaturation in the ambient air. The ice-supersaturated layer is found thicker and more humid in this case than predicted by the NWP model used. The simulated and observed contrail positions agree up to differences caused by uncertain wind data. The contrail widths, which depend on wake vortex spreading, ambient shear and turbulence, were partly wider than simulated.

    The purpose of this qualitative study was to examine the challenges that recent graduates of nurse anesthesia programs coped with during their anesthesia curriculum from their perspective. The initial research questions for this study were: From the graduates'perspective, what were the stressors that they encountered during their nurse anesthesia program? And how did they successfully negotiate those stressors in order to graduate from their program? This phenomenon was studied using grounded theory methodology. The data were collected by individual, semistructured, in-depth interviews with 12 recent nurse anesthesia program graduates, from 5 different nurse anesthesia programs, who have been out of school for less than 2 years. This exploration into student nurse anesthetist stress and coping articulates 3 phases of development as these students progressed through their program. The phases are transitioning in (first 9 months of program), finding their way (9 to 18 months into program), and transitioning out (18 to 28 months into program). Coping mechanisms employed by the participants were problem focused, emotion focused, and a combination of the 2. Recommendations for action and future research are discussed.

    The 'design for human factors' grounded theory explains 'how' human factors (HF) went from a reactive, after-injury programme in safety, to being proactively integrated into each step of the production design process. In this longitudinal case study collaboration with engineers and HF Specialists in a large electronics manufacturer, qualitative data (e.g. meetings, interviews, observations and reflections) were analysed using a grounded theory methodology. The central tenet in the theory is that when HF Specialists acclimated to the engineering process, language and tools, and strategically aligned HF to the design and business goals of the organisation, HF became a means to improve business performance. This led to engineers 'pulling' HF Specialists onto their team. HF targets were adopted into engineering tools to communicate HF concerns quantitatively, drive continuous improvement, visibly demonstrate change and lead to benchmarking. Senior management held engineers accountable for HF as a key performance indicator, thus integrating HF into the production design process. Practitioner Summary: Research and practice lack explanations about how HF can be integrated early in design of production systems. This three-year case study and the theory derived demonstrate how ergonomists changed their focus to align with design and business goals to integrate HF into the design process.

    2013-07-01

    Practice nursing in New Zealand is not well described in the literature. One survey illustrated that most of the New Zealand practice nurses sampled did not know of the country's two premier evidence-based health websites. A recent review compared general practice in the UK, New Zealand and Australia and found that whereas there had been significant developments in empowering the practice nurse workforce to run nurse-led clinics in the UK, New Zealand and Australia lagged behind. The aim of this reported constructivist grounded theory study was to investigate practice nurses' use of information. Conducted in Auckland, New Zealand, data were collected through ethnographic techniques in one general practice between September 2009 and January 2010 to enhance theoretical sensitivity to the area of information use. Subsequently, six experienced practice nurses (one twice after moving jobs) and five new graduate nurses from five different general practices were interviewed, using open-ended questions, between January 2010 and August 2011. Concurrent data collection and analysis occurred throughout the study period. The use of memos, the constant comparative method, data categorisation and finally, data abstraction resulted in the final theory of reciprocal role modelling. Experienced practice nurses role modelled clinical skills to new graduate nurses. Unexpectedly, new graduate nurses were unconscious experts at sourcing information and role modelled this skill to experienced practice nurses. Once this attribute was acknowledged by the experienced practice nurse, mutual learning occurred that enabled both groups of nurses to become better practitioners. Graduate nurses of the millennial generation were identified as a resource for experienced practice nurses who belong to the baby boomer generation and generation X. PMID:23638795

    The diagrammatic many-body perturbation theory is applied to the ground state of the water molecule within the algebraic approximation. Using four different basis sets, the total energy, the equilibrium OH bond length, and the equilibrium HOH bond angle are examined. The latter is found to be a particularly sensitive test of the convergence of perturbation expansions. Certain third-order results, which incorporate all two-, three-, and four-body effects, show evidence of good convergence properties.

    Background: The ability to find and retrieve information efficiently is an important skill for undergraduate nursing students. Yet a number of studies reveal that nursing students are not confident in their library searching skills and encounter barriers to retrieving relevant information for assignments. Objectives: This grounded theory study examined strategies used by students to locate information for class assignments and identified barriers to their success. Methods: Purposive sampling was used to recruit eleven students, who were asked to record their searching processes while completing a class assignment, and semi-structured, open-ended, audiotaped interviews took place to discuss the students' journals and solicit additional data. Methods of information seeking, strategies used to find information, and barriers to searching were identified. Results: Students' main concern was frustration caused by the challenge of choosing appropriate words or phrases to query databases. The central theme that united all categories and explained most of the variation among the data was “discovering vocabulary.” Conclusions: Teaching strategies to identify possible words and phrases to use when querying information sources should be emphasized more in the information literacy training of undergraduate nursing students.

    Teaching and learning science is hard, and the cognitive skills needed to be successful in science are complex. Science educators have explored a number of different ways to teach and learn science that impacts the widest variety of learners in a classroom. The grounded theory of adventuring explains both why scientific thinking is an evolutionarily important trait and illustrates a common thread throughout a variety of teaching and learning behaviors. Adventuring incorporates the dimensions of exploring, mavericking, and acquiring and applying skills that are the hallmarks of positive science education. The disciplines of psychology, sociology, biology, and ecology are connected in this study in order to fully illustrate the complexities of the subject. By exploring the psychology/sociology of teachers teaching science and students learning science, and connecting that to the biology of the hardware, this study explains how we could be teaching and learning science in a way for which our brains are best suited, and in ways that reach all learners.

    The precise measurement of fluctuations in ground-water temperature, based on monthly readings in shallow glacial-outwash aquifers (up to about 70 feet deep), is useful in the study of ground-water movement and recharge. In addition to the study of natural phenomena in the hydrologic cycle, thermometry may be used as a tool in making detailed studies of (1) the effects of inducing the infiltration of surface water, (2) artificial recharge, (3) the effects of injecting petroleum products or radioactive or other wastes into the ground, and (4) ground-water movement in mines.

    Large-scale ice-sheet dynamics pivot on the deformation and transport of subglacial sediment through changes in the basal sliding velocities of glaciers. Such unconsolidated, water-saturated glacigenic sediment, or till, is found to accumulate into sedimentary wedges, or till-deltas, in grounding zones separating floating ice shelves from grounded ice streams. In addition to affecting glacial slip, such sedimentation may serve to stabilise ice sheets against grounding-line retreat in response to rising sea levels. We present a fluid-mechanical explanation of the formation of these wedges in terms of the jump in hydrostatic loading and unloading of till across the grounding zone, and we compare our findings with geophysical data of sedimentary wedge formation at the modern-day grounding zone of Whillans Ice Stream, West Antarctica. We develop a theoretical model of wedge formation in which we treat both ice and till as viscous fluids spreading under gravity into an inviscid ocean and find that a similar wedge of underlying fluid accumulates around the grounding line in our series of fluid-mechanical laboratory experiments. The experiments were performed in a confined channel geometry. We extend our theory to unconfined geometries in which till deformation is resisted dominantly by vertical shear stresses and the flow of the overlying ice is resisted dominantly either by vertical shear stresses between the ice and till or by extensional stresses characteristic of floating ice shelves and shelfy streams. The former is relevant to less-lubricated, grounded ice sheets whereas the latter is relevant to well-lubricated ice streams, sliding over soft, deformable till of low viscosity and appreciable thickness. We formulate a local condition relating wedge slopes in each of the three scenarios and find a reasonable agreement with geophysical data.

    Little research has been done on the experience of diabetes-related amputation. The aim of this study was to allow amputees to describe their experiences of amputation and to generate grounded theory that will lead health professionals towards a more comprehensive understanding of the realities of post-amputation life. Unstructured interviews were conducted with five participants with a diabetes-related amputation living in a rural setting, and their respective carers. The interviews were analysed using Grounded Theory methods. Data analysis revealed three categories: 'imposed powerlessness', 'adaptive functionality' and 'endurance'. The impact of participant's amputations were influenced by continuing limb problems post-amputation and co-existing complications affecting their physical function. Medical errors and lack of awareness of the risks for diabetic amputations resulted in uncertainty and fear. The participants' sense of grief, loss and shock post operatively continued later as they came to terms with their awkwardness of movement, yet they moved forward developing their own sense of hope through a coping process that revealed remarkable ability to endure and exert control over lives that seemed to be at the whim of an ongoing disease process. The substantive theory resulting from this grounded theory study was conceptualised as 'A Path of Perpetual Resilience'. It is important that psychosocial and not just physical adjustment is considered an indicator for determining outcomes for these people, and that future care involves strategies to promote this. A greater sample size is required to determine if these findings are transferable to the general diabetes-related amputation population.

    The aim of the present study was to investigate low-income parents' experiences receiving, making meaning of, and applying sociocultural messages about childhood health and nutrition. Semi-structured interviews were conducted with parents from 16 low-income Early Head Start families. Verbatim interview transcripts, observations, field notes, documentary evidence, and follow-up participant checks were used during grounded theory analysis of the data. Data yielded a potential theoretical model of parental movement toward action involving (a) the culture and context influencing parents, (b) parents' sources of social and cultural messages, (c) parental values and engagement, (d) parental motivation for action, (e) intervening conditions impacting motivation and application, and (f) parent action taken on the individual and social levels. Parent characteristics greatly impacted the ways in which parents understood and applied health and nutrition information. Among other implications, it is recommended that educators and providers focus on a parent's beliefs, values, and cultural preferences regarding food and health behaviors as well as his/her personal/family definition of "health" when framing recommendations and developing interventions.

    2012-01-01

    Based upon a qualitative metasynthesis of 49 articles centered on clients' experiences of their conjoint couple and family therapy, the investigators constructed a grounded formal theory of Clients' Relational Conceptions of Conjoint Couple and Family Therapy Quality. The theory suggests from pretherapy conceptions to posttherapy reflections, clients' perceptions of conjoint couple and family therapy quality appear to consist of clients' constructed meanings regarding a series of interrelated relationships between clients and their therapists and therapy environments, between clients and themselves, between clients and other family members, and between process and outcome both inside and outside therapy. Within and across these relationships, clients appear to focus on expectations, connections, balance, and change when evaluating the quality of their clinical experiences. Based upon this theory, the investigators recommend that researchers continue to explore this clinical phenomenon and that therapists regularly seek clients' conceptions of quality in therapy.

    Giles, Tracey; King, Lindy; de Lacey, Sheryl

    2013-01-01

    The timing of the literature review in grounded theory has been debated for decades, with previous recommendations to delay the review now under question. Mounting evidence suggests that a preliminary review can enhance theoretical sensitivity and rigor and may lead to innovative insights. However, researchers must acknowledge the influence of prior knowledge during data analysis and theory development to avoid bias. This article critically examines the ongoing debate and recommends that we should not seek to avoid preconceptions but ensure that they are well grounded in evidence and always subject to further investigation, revision, and refutation. If used reflexively, a preliminary literature review may well enhance grounded theory research.

  15. A study of helicopter aerodynamics in ground effect

    NASA Astrophysics Data System (ADS)

    Pulla, Devi Prasad

    The flow around a helicopter is very complex; it becomes much more complex when it comes close to the ground. The presence of the ground changes the aerodynamic characteristics of the rotor and the flow environment becomes much more complex compared with that of flight out-of-ground effect (OGE) and hence the behavior of the rotor wake in the vicinity of the ground is challenging to predict. Under in-ground-effect(IGE) conditions, the wake collides with the ground and causes a significant perturbation to the flow near the blade. Significant interactions between the main rotor wake and the ground have been associated with the formation and passage of the ground vortex in forward flight. The presence of a ground vortex affects the handling qualities of the helicopter. The aim of this research is to capture the physics of the flow features and dynamics of ground effect flows around a rotorcraft, provide an understanding of the rotor wake/vortices near the ground, and generate rigorous models to accurately predict handling qualities, loads and moments acting on the rotor and the power requirements. A free vortex method is used to model the flowfield. The presence of the ground is modeled using the method of images and the lifting-surface theory is used to model each rotor blade. An initial wake geometry is assumed which is allowed to develop in time until the flowfield becomes periodic. The rotor wake is assumed to consist of only the tip vortices and the inboard sheet and the root vortex are neglected. The solution is stepped in time using an Adams-Moulton scheme with a Runge-Kutta starting formula. The wake structure after periodicity is reached is obtained for hover and different forward flight speeds. Also, the nature of the flowfield, as well as the formation of the ground vortex, is understood by obtaining the velocity contours on a longitudinal plane containing the rotor blade after periodicity is obtained. The unsteadiness in the velocities is quantified by

    1989-01-01

    A generation mechanism for radio waves in the frequency range 150 - 700 kHz observed by ground facilities is suggested in terms of an electromagnetic electron cyclotron instability driven by auroral electrons. The excited waves can propagate downward along the ambient magnetic field lines and are thus observable with ground facilities. The trapped auroral electrons are supposed to play an important role in the generation process, because they give rise to a thermal anisotropy which consequently leads to the instability. The present work is a natural extension of the theory proposed earlier by Wu et al. (1983) which was discussed in a different context but may be used to explain the observed waves originated at low altitudes. This paper presents a possible wave generation mechanism valid in the entire auroral field-line region of interest.

    Factitious disorder (FD) is poorly understood because of the elusiveness of sufferers. What is known is based on speculation from observational case studies and this is evident by the manifold diagnostic and treatment issues associated with FD. This study sought to fill the gap in the literature and overcome the elusiveness of FD sufferers by analysing their text communications in two online communities. One hundred twenty four posts by 57 members amounting to approximately 38,000 words were analysed using grounded theory. The analysis showed that contrary to current theories of FD, motivation is conscious and not unconscious, members did experience symptoms associated with the disorder, and they were also upset by their behaviour and wanted to recover but were deterred by fear. Furthermore, using the excessive appetitive model by Orford (2001) it is hypothesised that the characteristics of FD described by the members were congruent with those associated with addiction.

    Background: It seems we are now experiencing “responsibility problems” among medical trainees (MTs) and some of those recently graduated from medical schools in Iran. Training responsible professionals have always been one of the main concerns of medical educators. Nevertheless, there is a dearth of research in the literature on “responsibility” especially from the medical education point of view. Therefore, the present study was carried out with the aim of presenting a theoretical based framework for understanding how MTs approach their responsibilities in educational settings. Method: This qualitative study was conducted at Shiraz University of Medical Sciences (SUMS) using the grounded theory methodology. 15 MTs and 10 clinical experts and professional nurses were purposefully chosen as participants. Data was analyzed using the methodology suggested by Corbin and Strauss, 1998. Results: “Try to find acceptance toward expectations”, “try to be committed to meet the expectations” and “try to cope with unacceptable expectations” were three main categories extracted based on the research data. Abstractly, the main objective for using these processes was “to preserve the integrity of student identity” which was the core category of this research too. Moreover, it was also found that practically, “responsibility” is considerably influenced by lots of positive and negative contextual and intervening conditions. Conclusion: “Acceptance” was the most decisive variable highly effective in MTs’ responsibility. Therefore, investigating the “process of acceptance” regarding the involved contextual and intervening conditions might help medical educators correctly identify and effectively control negative factors and reinforce the constructive ones that affect the concept of responsibility in MTs.

    This paper discusses the slope stability and landslide propensity of several hydroelectric plant earth dams throughout the Soviet Union from the standpoint of slide theory and compares the research of several Soviet institutions into this problem with existing standards and recommendations on dam stability and reliability. The comparisons are made for earth dams having a soft ground foundation under static loading conditions. Applicable properties are discussed for a wide range of soils and rocks including clays, loams, sands, alluvials, and soft and hard gravels. Seismic effects are not discussed.

    This paper discusses two qualitative research methods, phenomenography and grounded theory. We introduce both methods' data collection and analysis processes and the type or results you may get at the end by using examples from computing education research. We highlight some of the similarities and differences between the aim, data collection and analysis phases and the type of resulting outcomes of these methods. We also discuss the challenges and threats the both methods may pose to the researcher. We conclude that while aimed at tackling different types of research questions, both of these methods provide computing education researchers a useful tool in their research method toolbox.

    Little is known about how to systematically integrate complex qualitative studies within the context of randomized controlled trials. A two-phase sequential explanatory mixed methods study was conducted in Canada to understand how women decide to disclose intimate partner violence in emergency department settings. Mixing a RCT (with a subanalysis of data) with a grounded theory approach required methodological modifications to maintain the overall rigour of this mixed methods study. Modifications were made to the following areas of the grounded theory approach to support the overall integrity of the mixed methods study design: recruitment of participants, maximum variation and negative case sampling, data collection, and analysis methods. Recommendations for future studies include: (1) planning at the outset to incorporate a qualitative approach with a RCT and to determine logical points during the RCT to integrate the qualitative component and (2) consideration for the time needed to carry out a RCT and a grounded theory approach, especially to support recruitment, data collection, and analysis. Data mixing strategies should be considered during early stages of the study, so that appropriate measures can be developed and used in the RCT to support initial coding structures and data analysis needs of the grounded theory phase.

    Often older people, while maintaining a level of independence, rely on family members to provide care and assistance. Caregivers who are also registered nurses (RNs) may provide a different perspective around the experience when their older relative is admitted to acute care. The aim of our research was to investigate and develop theory regarding nursing care provision as described by RNs, who were family caregivers to older adults, when that older adult was admitted to acute care. Over a six-month period in 2011, RNs meeting this criterion (n = 12) were interviewed individually. We identified two central categories: "Culture of Neglect" and "Vigil by the Bedside". The core category "Normalization of Neglect" was identified as the theory, grounded in the data the participants provided which described a culture of neglect that had normalized poor nursing care. These findings highlight the issue of neglect and abuse, and further investigation is warranted.

    This report describes an initial investigation of propagation near the ground in forested terrain at a frequency of 110.6 MHz. The objective was to study propagation effects that influence the illumination of ground-clutter targets by a ground-based radar. We used as a transmitter an aircraft-navigation aid, the VHF omnidirectional range at Gardner, Massachusetts. Ground-based measurements of signal strength at heights from 2 to 15 ft above the ground were made at two locations, 2.2 and 8.8 miles away, and the field strengths corresponding to free-space propagation at each location were measured with a helicopter hovering over the site of the ground-based measurements at sufficient altitude to avoid terrain-diffraction effects. The results of the ground-based measurements are compared with calculations that model the propagation effects on the basis of terrain profiles determined directly from relief maps with corrections for tree height. The model took into account diffraction by masking hills. In addition specular reflection from the open fields immediately in front of the receiving antenna at both sites was found to produce the steep gradients in field strength observed below a height of 10 ft above ground.

  6. Theory of plasma contactors in ground-based experiments and low Earth orbit

    1990-01-01

    Previous theoretical work on plasma contactors as current collectors has fallen into two categories: collisionless double layer theory (describing space charge limited contactor clouds) and collisional quasineutral theory. Ground based experiments at low current are well explained by double layer theory, but this theory does not scale well to power generation by electrodynamic tethers in space, since very high anode potentials are needed to draw a substantial ambient electron current across the magnetic field in the absence of collisions (or effective collisions due to turbulence). Isotropic quasineutral models of contactor clouds, extending over a region where the effective collision frequency upsilon sub e exceeds the electron cyclotron frequency omega sub ce, have low anode potentials, but would collect very little ambient electron current, much less than the emitted ion current. A new model is presented, for an anisotropic contactor cloud oriented along the magnetic field, with upsilon sub e less than omega sub ce. The electron motion along the magnetic field is nearly collisionless, forming double layers in that direction, while across the magnetic field the electrons diffuse collisionally and the potential profile is determined by quasineutrality. Using a simplified expression for upsilon sub e due to ion acoustic turbulence, an analytic solution has been found for this model, which should be applicable to current collection in space. The anode potential is low and the collected ambient electron current can be several times the emitted ion current.

    1955-01-01

    The objective of the Ground Water Branch is to evaluate the occurrence, availability, and quality of ground water.  The science of ground-water hydrology is applied toward attaining that goal.  Although many ground-water investigations are of a qualitative nature, quantitative studies are necessarily an integral component of the complete evaluation of occurrence and availability.  The worth of an aquifer as a fully developed source of water depends largely on two inherent characteristics: its ability to store, and its ability to transmit water.  Furthermore, quantitative knowledge of these characteristics facilitates measurement of hydrologic entities such as recharge, leakage, evapotranspiration, etc.  It is recognized that these two characteristics, referred to as the coefficients of storage and transmissibility, generally provide the very foundation on which quantitative studies are constructed.  Within the science of ground-water hydrology, ground-water hydraulics methods are applied to determine these constats from field data.

    Woods, Phillip; Gapp, Rod; King, Michelle A

    2016-06-01

    Grounded theory is a qualitative research methodology that aims to explain social phenomena, e.g. why particular motivations or patterns of behaviour occur, at a conceptual level. Developed in the 1960s by Glaser and Strauss, the methodology has been reinterpreted by Strauss and Corbin in more recent times, resulting in different schools of thought. Differences arise from different philosophical perspectives concerning knowledge (epistemology) and the nature of reality (ontology), demanding that researchers make clear theoretical choices at the commencement of their research when choosing this methodology. Compared to other qualitative methods it has ability to achieve understanding of, rather than simply describing, a social phenomenon. Achieving understanding however, requires theoretical sampling to choose interviewees that can contribute most to the research and understanding of the phenomenon, and constant comparison of interviews to evaluate the same event or process in different settings or situations. Sampling continues until conceptual saturation is reached, i.e. when no new concepts emerge from the data. Data analysis focusses on categorising data (finding the main elements of what is occurring and why), and describing those categories in terms of properties (conceptual characteristics that define the category and give meaning) and dimensions (the variations within properties which produce specificity and range). Ultimately a core category which theoretically explains how all other categories are linked together is developed from the data. While achieving theoretical abstraction in the core category, it should be logical and capture all of the variation within the data. Theory development requires understanding of the methodology not just working through a set of procedures. This article provides a basic overview, set in the literature surrounding grounded theory, for those wanting to increase their understanding and quality of research output.

    Baseline values of immunoreactive ACTH were established in the normal healthy adult. Normal levels of ACTH secretion were determined for both the male and the female in circulating plasma and serum. The data obtained in these studies are particularly significant in that the sampling was carefully controlled; only healthy employed individuals of both sexes were tested in a routine work situation that would not be considered conducive to stress. It has been found that alterations in the classically described circadian rhythm of ACTH secretion can occur when activities (such as work/rest cycles) are imposed on the individual studied. These changes can be demonstrated even when there is no appreciable change noted in the rhythm of hydrocortisone secretion.

    1996-07-01

    This report documents research pertaining to conservatism and variability in seismic risk estimates. Specifically, it examines whether or not artificial motions produce unrealistic evaluation demands, i.e., demands significantly inconsistent with those expected from real earthquake motions. To study these issues, two types of artificial motions are considered: (a) motions with smooth response spectra, and (b) motions with realistic variations in spectral amplitude across vibration frequency. For both types of artificial motion, time histories are generated to match target spectral shapes. For comparison, empirical motions representative of those that might result from strong earthquakes in the Eastern U.S. are also considered. The study findings suggest that artificial motions resulting from typical simulation approaches (aimed at matching a given target spectrum) are generally adequate and appropriate in representing the peak-response demands that may be induced in linear structures and equipment responding to real earthquake motions. Also, given similar input Fourier energies at high-frequencies, levels of input Fourier energy at low frequencies observed for artificial motions are substantially similar to those levels noted in real earthquake motions. In addition, the study reveals specific problems resulting from the application of Western U.S. type motions for seismic evaluation of Eastern U.S. nuclear power plants.

    Three possible applications of thermal (8-14 microns) remote sensing to detailed hydrogeologic studies are discussed in this paper: (1) the direct detection of seeps and springs, (2) the indirect evaluation of shallow ground water flow through its thermal effects on the land surface, and (3) the indirect location of small volumes of ground water inflow into surface water bodies. An investigation carried out with this purpose in an area containing a complex shallow ground water flow system indicates that the interpretation of the thermal imageries is complicated by many factors, among which the most important are: (1) altitude, angle of view, and thermal-spatial resolution of the sensor; (2) vegetation type, density, and vigor; (3) topography; (4) climatological and micrometeorological effects; (5) variation in soil type and soil moisture; (6) variation in volume and temperature of ground water inflow; (7) the hydraulic characteristics of the receiving water body, and (8) the presence of decaying organic material.

  16. Ab initio molecular orbital/Rice-Ramsperger-Kassel-Marcus theory study of multichannel rate constants for the unimolecular decomposition of benzene and the H+C6H5 reaction over the ground electronic state

    The potential energy surface for the unimolecular decomposition of benzene and H+C6H5 recombination has been studied by the ab initio G2M(cc, MP2) method. The results show that besides direct emission of a hydrogen atom occurring without an exit channel barrier, the benzene molecule can undergo sequential 1,2-hydrogen shifts to o-, m-, and p-C6H6 and then lose a H atom with exit barriers of about 6 kcal/mol. o-C6H6 can eliminate a hydrogen molecule with a barrier of 121.4 kcal/mol relative to benzene. o- and m-C6H6 can also isomerize to acyclic isomers, ac-C6H6, with barriers of 110.7 and 100.6 kcal/mol, respectively, but in order to form m-C6H6 from benzene the system has to overcome a barrier of 108.6 kcal/mol for the 1,2-H migration from o-C6H6 to m-C6H6. The bimolecular H+C6H5 reaction is shown to be more complicated than the unimolecular fragmentation reaction due to the presence of various metathetical processes, such as H-atom disproportionation or addition to different sites of the ring. The addition to the radical site is barrierless, the additions to the o-, m-, and p-positions have entrance barriers of about 6 kcal/mol and the disproportionation channel leading to o-benzyne+H2 has a barrier of 7.6 kcal/mol. The Rice-Ramsperger-Kassel-Marcus and transition-state theory methods were used to compute the total and individual rate constants for various channels of the two title reactions under different temperature/pressure conditions. A fit of the calculated total rates for unimolecular benzene decomposition gives the expression 2.26×1014exp(-53 300/T)s-1 for T=1000-3000 K and atmospheric pressure. This finding is significantly different from the recommended rate constant, 9.0×1015exp(-54 060/T) s-1, obtained by kinetic modeling assuming only the H+C6H5 product channel. At T=1000 K, the branching ratios for the formation of H+C6H5 and ac-C6H6 are 29% and 71%, respectively. H+C6H5 becomes the major channel at T⩾1200 K. The total rate for the bimolecular H

    Stimulated by growing interest in the organizational and performance leadership components of Olympic success, sport psychology researchers have identified performance director-led culture change as a process of particular theoretical and applied significance. To build on initial work in this area and develop practically meaningful understanding, a pragmatic research philosophy and grounded theory methodology were engaged to uncover culture change best practice from the perspective of newly appointed performance directors. Delivered in complex and contested settings, results revealed that the optimal change process consisted of an initial evaluation, planning, and impact phase adjoined to the immediate and enduring management of a multidirectional perception- and power-based social system. As the first inquiry of its kind, these findings provide a foundation for the continued theoretical development of culture change in Olympic sport performance teams and a first model on which applied practice can be based.

    2016-05-01

    We investigate the order-by-order convergence behavior of many-body perturbation theory (MBPT) as a simple and efficient tool to approximate the ground-state energy of closed-shell nuclei. To address the convergence properties directly, we explore perturbative corrections up to 30th order and highlight the role of the partitioning for convergence. The use of a simple Hartree-Fock solution for the unperturbed basis leads to a convergent MBPT series for soft interactions, in contrast to the divergent MBPT series obtained with a harmonic oscillator basis. For larger model spaces and heavier nuclei, where a direct high-order MBPT calculation is not feasible, we perform third-order calculations and compare to advanced ab initio coupled-cluster results for the same interactions and model spaces. We demonstrate that third-order MBPT provides ground-state energies for nuclei up into the tin isotopic chain in excellent agreement with the best available coupled-cluster calculations at a fraction of the computational cost.

    The present study aimed to develop a theoretical understanding of the role of breast reconstruction in women's self-image. Semi-structured interviews were conducted with 10 women from breast cancer support groups who had undergone breast reconstruction surgery. A grounded theory methodology was used to explore their experiences. The study generated a model of 'breast cancer, breast reconstruction and self-image', with a core category entitled 'feeling like me again' and two principal categories of 'normal appearance' and 'normal life'. A further two main categories, 'moving on' and 'image of sick person' were generated. The results indicated a role of breast reconstruction in several aspects of self-image including the restoration of pre-surgery persona, which further promoted adjustment.

    2012-01-01

    During conversation, interactants draw on their shared communicative context and history ("common ground") to help decide what to say next, tailoring utterances based on their knowledge of what the listener knows. The use of common ground draws on an understanding of the thoughts and feelings of others to create and update a model of what is known by the other person, employing cognitive processes such as theory of mind. We tested the hypothesis that the ventromedial prefrontal cortex (vmPFC), a neural region involved in processing and interpreting social and emotional information, would be critical for the development and use of common ground. We studied seven patients with bilateral vmPFC damage and seven age-, sex-, and education-matched healthy comparison participants, each interacting with a familiar partner. Across 24 trials, participants verbally directed their partners how to arrange a set of 12 abstract tangram cards. Our hypothesis was not supported: the vmPFC and healthy comparison groups showed similar development and use of common ground, evident in reduction in time and words used to describe the cards, similar increases in the use of definite references (e.g., the horse), and comparable use of verbal play (playful language) in their interactions. These results argue against the idea that the vmPFC is critical for the development and use of common ground in social interaction. We propose that a cognitive and neuroanatomical bifurcation in theory of mind processes may explain this outcome. The vmPFC may be important for affective theory of mind (the ability to understand another's feelings); however, the development and use of common ground in social interaction may place higher demands on the ability to understand another's knowledge, or cognitive theory of mind, which may not require the vmPFC.

    Clients, patients, families, and communities must be conceived as partners in care delivery, not just as recipients (D'Amour, D. & Oandasan, I. (2005). Journal of Interprofessional Care, 19(Suppl.), 8-20). Health-care students need an opportunity to understand community member self-determination, partnership, and empowerment (Scheyett, A., & Diehl, M. ( 2004 ). Social Work Education, 23(4), 435-450), within the frame of interprofessional education (IPE) where community members are involved as teachers and learners. The aim of this grounded theory research was to determine the conditions that support health-care students to learn with, from, and about community members. This study took place in a shelter for the homeless where nursing and social work students learned interprofessionally along with residents and clients of the shelter. Data were gathered through 7 months of participant observation, interviews, and focus groups. The interprofessional co-learning theory that emerged introduces the three phases of entering, engaging, and emerging, which co-learners experienced at different levels of intensity. This article outlines the conditions that support each of these phases of the co-learning process. This interprofessional co-learning theory provides a basis for further development and evaluation of IPE programs that strive to actively include community members as teachers and learners, experts, and novices together with service providers, students, and faculty members.

    2008-01-01

    The authors used a videotape-assisted recall procedure to study the content of family therapists' inner conversations during individual sessions with a standardized client. Grounded theory was used to analyze therapists' reflections, resulting in a taxonomy of 282 different codes in a hierarchical tree structure of six levels, organized into four general domains: attending to client process; processing the client's story; focusing on therapists' own experience; and managing the therapeutic process. In addition to providing a descriptive model of therapists' inner conversation, this research led to an appreciation of the wealth of therapists' inner conversation. In particular, the authors found that therapists work hard to create an intersubjective space within which to talk by trying to be in tune with their clients and by using clients as a guide.

    Divorced parents face distinct challenges in providing care for chronically ill children. Children's residence in two households necessitates the development of family-specific strategies to ensure coparents' supervision of regimen adherence and the management of children's health care. Utilizing a risk and resilience perspective, a grounded theory study was conducted with 14 divorced parents of children with chronic illnesses. The importance of trust, gender, and relationships with third-party care providers emerged as key themes related to the development of effective coparenting relationships for maintaining children's health. Divorced parents were best able to support the management of their children's chronic conditions when care providers operated as neutral third parties and intermediaries. Collaborative family care may require health care practitioners to avoid being drawn into contentious inter-parental conflicts. PMID:27021310

    2016-03-01

    This article reports on an empirical study that aimed to design a practice-based theory about collaboration on the local implementation of a nationally developed health-promoting intervention. The study's objective is to better understand the dynamic process of complex collaboration. The research is based on a Delphi study among some 100 individuals in local and regional networks, in which various professionals work together to implement the BeweegKuur, which translates as 'course of exercise'. The BeweegKuur is a combined lifestyle intervention aimed at promoting sufficient physical exercise and a healthy diet among people in the Netherlands who are overweight and at risk of diabetes. The Delphi study in three rounds systematically and interactively constructs a common perspective on implementation, reflecting stakeholders' ideas about the collaboration and providing an insight into how these ideas are influenced by the context of the implementation. The statistical and qualitative analyses of the responses to the feedback in the Delphi study form the basis for this practice-based theory on complex collaboration, called the theory of gradual commonality. During interaction, consensus gradually emerges about co-creation as a collaboration strategy. Co-creation leaves room for various ways of achieving the ambitions of the BeweegKuur. This article discusses the importance of this practice-based theory and the value of the Delphi research strategy for promoting health.

  9. A theory for modeling ground-water flow in heterogeneous media

    USGS Publications Warehouse

    Cooley, Richard L.

    2004-01-01

    Construction of a ground-water model for a field area is not a straightforward process. Data are virtually never complete or detailed enough to allow substitution into the model equations and direct computation of the results of interest. Formal model calibration through optimization, statistical, and geostatistical methods is being applied to an increasing extent to deal with this problem and provide for quantitative evaluation and uncertainty analysis of the model. However, these approaches are hampered by two pervasive problems: 1) nonlinearity of the solution of the model equations with respect to some of the model (or hydrogeologic) input variables (termed in this report system characteristics) and 2) detailed and generally unknown spatial variability (heterogeneity) of some of the system characteristics such as log hydraulic conductivity, specific storage, recharge and discharge, and boundary conditions. A theory is developed in this report to address these problems. The theory allows construction and analysis of a ground-water model of flow (and, by extension, transport) in heterogeneous media using a small number of lumped or smoothed system characteristics (termed parameters). The theory fully addresses both nonlinearity and heterogeneity in such a way that the parameters are not assumed to be effective values. The ground-water flow system is assumed to be adequately characterized by a set of spatially and temporally distributed discrete values, ?, of the system characteristics. This set contains both small-scale variability that cannot be described in a model and large-scale variability that can. The spatial and temporal variability in ? are accounted for by imagining ? to be generated by a stochastic process wherein ? is normally distributed, although normality is not essential. Because ? has too large a dimension to be estimated using the data normally available, for modeling purposes ? is replaced by a smoothed or lumped approximation y?. (where y is a

  13. Determination of the ground albedo and the index of absorption of atmospheric particulates by remote sensing. I - Theory

    A statistical technique is developed for inferring the optimum values of the ground albedo and the effective imaginary term of the complex refractive index of atmospheric particulates. The procedure compares measurements of the ratio of the hemispheric diffuse to directly transmitted solar flux density at the earth's surface with radiative transfer computations of the same as suggested by Herman et al. (1975). A detailed study is presented which shows the extent to which the ratio of diffuse to direct solar radiation is sensitive to many of the radiative transfer parameters. Results indicate that the optical depth and size distribution of atmospheric aerosol particles are the two parameters which uniquely specify the radiation field to the point where ground albedo and index of absorption can be inferred. Varying the real part of the complex refractive index of atmospheric particulates as well as their vertical distribution is found to have a negligible effect on the diffuse-direct ratio. The statistical procedure utilizes a semi-analytic gradient search method from least-squares theory and includes a detailed error analysis.

    2007-05-01

    Long time series of ground-based plant phenology, as well as more than two decades of satellite-derived phenological metrics, are currently available to assess the impacts of climate variability and trends on terrestrial vegetation. Traditional plant phenology provides very accurate information on individual plant species, but with limited spatial coverage. Satellite phenology allows monitoring of terrestrial vegetation on a global scale and provides an integrative view at the landscape level. Linking the strengths of both methodologies has high potential value for climate impact studies. We compared a multispecies index from ground-observed spring phases with two types (maximum slope and threshold approach) of satellite-derived start-of-season (SOS) metrics. We focus on Switzerland from 1982 to 2001 and show that temporal and spatial variability of the multispecies index correspond well with the satellite-derived metrics. All phenological metrics correlate with temperature anomalies as expected. The slope approach proved to deviate strongly from the temporal development of the ground observations as well as from the threshold-defined SOS satellite measure. The slope spring indicator is considered to indicate a different stage in vegetation development and is therefore less suited as a SOS parameter for comparative studies in relation to ground-observed phenology. Satellite-derived metrics are, however, very susceptible to snow cover, and it is suggested that this snow cover should be better accounted for by the use of newer satellite sensors.

    2014-01-01

    Collaboration by two grounded theory researchers, who each had developed a learning continuum instrument, led to the emergence of a new tool for assessment of learning powered mobility use. We undertook a rigorous process of comparative reanalysis that included merging, modifying, and expanding our previous research findings. A new instrument together with its facilitating strategies emerged in the course of revisits to our existing rich account of data taken from real environment powered mobility practice over an extensive time period. Instrument descriptors, categories, phases, and stages allow a facilitator to assess actual phase and plot actual occupational performance and provide a learner with the just right challenge through the learning process. Facilitating strategies are described for each of the phases and provide directions for involvement during learner performance. The learning approach is led by a belief system that the intervention is user-led, working in partnership and empowering the learner. The new assessment tool is inclusive of every potential powered mobility user because it focuses on the whole continuum of the learning process of powered mobility use from novice to expert. The new tool was appraised by clinicians and has been used successfully in clinical practice in the United Kingdom and Sweden.

  1. Negotiating the equivocality of palliative care: a grounded theory of team communicative processes in inpatient medicine.

    In the majority of U.S. hospitals, inpatient medicine teams make palliative care decisions in the absence of a formalized palliative system. Using a grounded theory approach, interviews with inpatient team members were systematically analyzed to uncover how participants conceptualize palliative care and how they regard the communicative structures that underlie its delivery. During analysis, Weick's model of organizing emerged as a framework that fit the data. The 39 participant inpatient team members discussed palliative care as primarily a communicative process. Themes describing the meaning of palliative care emerged around the concepts of receiver of care, timeline of care, and location of care. The emerging model included four stages in the communicative processes of inpatient palliative care: (a) interpret the need, (b) initiate the conversation, (c) integrate the processes, and (d) identify what works. In contrast to stable, focused palliative care teams or hospice care teams, which have prescribed patient populations and processes, the inpatient medicine team faces the equivocality of providing palliative care within a broader practice. This research offers a four-phase model to show how these inpatient teams communicate within this context. Implications for the provision of palliative care are discussed.

    Now available on the Internet is a web site for the U.S. Geological Survey's (USGS) National Water-Quality Assessment (NAWQA) Program- High Plains Regional Ground-Water Study. The purpose of the web site is to provide public access to a wide variety of information on the USGS investigation of the ground-water resources within the High Plains aquifer system. Typical pages on the web site include the following: descriptions of the High Plains NAWQA, the National NAWQA Program, the study-area setting, current and past activities, significant findings, chemical and ancillary data (which can be downloaded), listing and access to publications, links to other sites about the High Plains area, and links to other web sites studying High Plains ground-water resources. The High Plains aquifer is a regional aquifer system that underlies 174,000 square miles in parts of eight States (Colorado, Kansas, Nebraska, New Mexico, Oklahoma, South Dakota, Texas, and Wyoming). Because the study area is so large, the Internet is an ideal way to provide project data and information on a near real-time basis. The web site will be a collection of living documents where project data and information are updated as it becomes available throughout the life of the project. If you have an interest in the High Plains area, you can check this site periodically to learn how the High Plains NAWQA activities are progressing over time and access new data and publications as they become available.

  4. Studies in Quantum Field Theory

    NASA Astrophysics Data System (ADS)

    Bastianelli, Fiorenzo

    We analyze several topics in quantum field theory, mainly motivated by their role in the formulation of string theories. The common theme in what follows is the implementation of symmetries, such as local supersymmetry or BRST symmetry, through an action principle and the analysis of anomalies, the latter describing the breakdown of these symmetries at the quantum level. In the first part of this dissertation, we analyze "chiral bosons", i.e. massless scalar fields in a two -dimensional spacetime propagating in only one of the two light-cone directions. We present a general method for constructing couplings for chiral bosons and give details for the coupling to supergravity. The notion of a two dimensional chiral boson is generalized in d = 4k + 2 spacetime dimensions to that of a self-dual antisymmetric tensor field. We derive the coupling to gravity and compute the gravitational anomalies using the Feynman rules obtained from the action. We find agreement with the important work of Alvarez-Gaume and Witten, who conjectured the relevant Feynman rules. Our result therefore completes and justifies the Alvarez-Gaume-Witten findings. For the case of d = 2 we also show how to use the method of Fujikawa for computing anomalies from the non-invariance of the path integral measure. We obtain the full effective action by integrating the anomaly equation. In the second part we focus on a method for computing the consistent anomalies in the Fujikawa scheme. In a first application, we derive the consistent regulators for the various fields of the quantum action of the spinning string in superspace. These regulators produce the anomalies which satisfy the Wess-Zumino consistency conditions. In a second application, we analyze the anomalous structure of the Green-Schwarz formulation of the heterotic string. We find anomalies which generically do not cancel on an arbitrary world-sheet manifold. This raises questions concerning the possible validity of such a formulation of

    Graduate nurses in general practice became a feature of New Zealand's health care system in 2008 following an expansion of the New Entrant to Practice Programme. General practice in New Zealand comprises general practitioner business owners who employ nursing and administration staff. Practice nurses are an ageing workforce in New Zealand, it is imperative therefore to attract younger nurses into general practice. This paper reports a section of the findings from a constructivist grounded theory study which examines the use of information by practice nurses in New Zealand. Initially data were collected using the ethnographic technique of observation and field notations in one general practice. Theoretical sensitivity to the value of role models was heightened by this first phase of data collection. A total of eleven practice nurses were interviewed from six general practices. One practice nurse agreed to a second interview; five of the interviewees were new graduate nurses and the other six were experienced practice nurses. The grounded theory constructed from this research was reciprocal role modelling which comprises the following three categories, becoming willing, realising potential and becoming a better practitioner. Graduate nurses and experienced practice nurses enter into a relationship of reciprocal role modelling. Becoming willing, the first core category of this grounded theory features three sub-categories: building respectful relationships, proving yourself and discerning decision making which are reported in this paper. Findings from this study may address the reported phenomenon of 'transition shock' of newly graduated nurses in the work place.

    The U.S. Geological Survey (USGS) collects ground-water data and conducts studies to monitor hydrologic conditions, to better define ground-water resources, and address problems related to water supply and water quality. Data collected as part of ground-water studies include geologic, geophysical, hydraulic property, water level, and water quality. A ground-water-level network has been established throughout most of the State of Georgia, and ground-water-quality networks have been established in the cities of Albany, Savannah, and Brunswick and in Camden County, Georgia. Ground-water levels are monitored continuously in a network of wells completed in major aquifers of the State. This network includes 17 wells in the surficial aquifer, 12 wells in the upper and lower Brunswick aquifers, 73 wells in the Upper Floridan aquifer, 10 wells in the Lower Floridan aquifer and underlying units, 12 wells in the Claiborne aquifer, 1 well in the Gordon aquifer, 11 wells in the Clayton aquifer, 11 wells in the Cretaceous aquifer system, 2 wells in Paleozoic-rock aquifers, and 7 wells in crystalline-rock aquifers. In this report, data from these 156 wells were evaluated to determine whether mean-annual ground-water levels were within, below, or above the normal range during 2001, based on summary statistics for the period of record. Information from these summaries indicates that water levels during 2001 were below normal in almost all aquifers monitored, largely reflecting climatic effects from drought and pumping. In addition, water-level hydrographs for selected wells indicate that water levels have declined during the past 5 years (since 1997) in almost all aquifers monitored, with water levels in some wells falling below historical lows. In addition to continuous water-level data, periodic measurements taken in 52 wells in the Camden County-Charlton County area, and 65 wells in the city of Albany-Dougherty County area were used to construct potentiometric-surface maps for

    Ground-source heat pump systems are one of the promising new energy technologies that has shown rapid increase in usage over the past ten years in the United States. These systems offer substantial benefits to consumers and utilities in energy (kWh) and demand (kW) savings. The purpose of this study was to determine what existing monitored data was available mainly from electric utilities on heat pump performance, energy savings and demand reduction for residential, school and commercial building applications. In order to verify the performance, information was collected for 253 case studies from mainly utilities throughout the United States. The case studies were compiled into a database. The database was organized into general information, system information, ground system information, system performance, and additional information. Information was developed on the status of demand-side management of ground-source heat pump programs for about 60 electric utility and rural electric cooperatives on marketing, incentive programs, barriers to market penetration, number units installed in service area, and benefits.

    This paper describes the use of the ''Decoupled Method'' (See Part I) for studying and detailing important facilities of the ground system of the Itaipu Generating Complex (13000 MW), including 4 large nearby substations, interconnected by the ACSR ground-wires of several 500kV and 220kV transmission lines. Of permanent importance was the reduction of ground potential obtained by the utilization of lines with ACSR ground-wires on the spans near the substations. This paper also presents the theoretical justification for the ''decoupling technique'' used as the Step No. 4 of the ''Decoupled Method''. It is also shown that the subdivision of the fault current into two components (''self-neutralized'' and ''non-neutralized'' components) together with the concepts of ''virtual circuit'' and ''real circuit'' as used in the method, are powerful analytical tools for the electrical engineers dealing with the design and performance of ground systems.

    2013-12-01

    This work presents the development of layered crust models for the study of the grounding system of Agua Doce Windfarm Complex, localized north of Santa Catarina State, Brazil. This complex has 6 windfarms with a total of 86 aerogenerators, distributed by an area of about 220 km2. Agua Doce Complex is located at the top border of Santa Catarina state, directly over the basalts of Serra Geral Formation, upper layer of the Parana Sedimentar Basin, which lays over the huge confined Guarani Aquifer, formed by varied sediments accumulated over 250 my (from Ordovician to Triassic Period). Below Agua Doce, the Serra Geral Formation is around 1km deep, being the Parana crystalline basement about 3.6 km deep. Windfarms are extensive power plants, occupying wide areas. The grounding of each tower is composed by the huge amount of steel rebars, inside the tower foundations, and complemented by buried cooper cable rings. The tower groundings are interconnected by means of buried cooper cable or by aerial steel cables, the latter fixed on top of the distribution lines that connect the aerogenerators to the main substation. The steel cables of the aerial lines are also grounded by means of spaced grounding rods. For the simulation of this wide grounding system, it is essential the previous development of a layered electrical resistivity crust model. This model will be dependent on the quantity and quality of resistivity measurements, and also on the adopted technique to reduce the large amount of measured values to an average apparent resistivity curve, which shall be representative of the initial data set. The desired crust model should represent the different resistivity values for at least 10 km deep, including a detailed representation of near-surface soil layers, down to 100 meters, considering that this is the medium where the ground electrodes will be buried. For this project, soil resistivity measurements were made close to each of the 86 aerogenerators, by means of

    Multiyear studies were done to examine meteorologic and hydrogeologic controls on ephemeral streamflow and focused ground-water recharge at eight sites across the arid and semiarid southwestern United States. Campaigns of intensive data collection were conducted in the Great Basin, Mojave Desert, Sonoran Desert, Rio Grande Rift, and Colorado Plateau physiographic areas. During the study period (1997 to 2002), the southwestern region went from wetter than normal conditions associated with a strong El Ni?o climatic pattern (1997?1998) to drier than normal conditions associated with a La Ni?a climatic pattern marked by unprecedented warmth in the western tropical Pacific and Indian Oceans (1998?2002). The strong El Ni?o conditions roughly doubled precipitation at the Great Basin, Mojave Desert, and Colorado Plateau study sites. Precipitation at all sites trended generally lower, producing moderate- to severe-drought conditions by the end of the study. Streamflow in regional rivers indicated diminishing ground-water recharge conditions, with annual-flow volumes declining to 10?46 percent of their respective long-term averages by 2002. Local streamflows showed higher variability, reflecting smaller scales of integration (in time and space) of the study-site watersheds. By the end of the study, extended periods (9?15 months) of zero or negligible flow were observed at half the sites. Summer monsoonal rains generated the majority of streamflow and associated recharge in the Sonoran Desert sites and the more southerly Rio Grande Rift site, whereas winter storms and spring snowmelt dominated the northern and westernmost sites. Proximity to moisture sources (primarily the Pacific Ocean and Gulf of California) and meteorologic fluctuations, in concert with orography, largely control the generation of focused ground-water recharge from ephemeral streamflow, although other factors (geology, soil, and vegetation) also are important. Watershed area correlated weakly with focused

    2015-12-01

    We study ground-state properties of a two-site, two-electron Holstein model describing two molecules coupled indirectly via electron-phonon interaction by using both exact diagonalization and self-consistent diagrammatic many-body perturbation theory. The Hartree and self-consistent Born approximations used in the present work are studied at different levels of self-consistency. The governing equations are shown to exhibit multiple solutions when the electron-phonon interaction is sufficiently strong, whereas at smaller interactions, only a single solution is found. The additional solutions at larger electron-phonon couplings correspond to symmetry-broken states with inhomogeneous electron densities. A comparison to exact results indicates that this symmetry breaking is strongly correlated with the formation of a bipolaron state in which the two electrons prefer to reside on the same molecule. The results further show that the Hartree and partially self-consistent Born solutions obtained by enforcing symmetry do not compare well with exact energetics, while the fully self-consistent Born approximation improves the qualitative and quantitative agreement with exact results in the same symmetric case. This together with a presented natural occupation number analysis supports the conclusion that the fully self-consistent approximation describes partially the bipolaron crossover. These results contribute to better understanding how these approximations cope with the strong localizing effect of the electron-phonon interaction.

    2013-01-01

    Background Under the National Rural Health Mission, the current emphasis is on achieving universal institutional births through incentive schemes as part of reforms related to childbirth in India. There has been rapid progress in achieving this goal. To understand the choices made as well as practices and perceptions related to childbirth amongst tribal women in Gujarat and how these have been influenced by modernity in general and modernity brought in through maternal health policies. Method A model depicting the transition in childbirth practices amongst tribal women was constructed using the grounded theory approach with; 8 focus groups of women, 5 in depth interviews with traditional birth attendants, women, and service providers and field notes on informal discussions and observations. Results A transition in childbirth practices across generations was noted, i.e. a shift from home births attended by Traditional Birth Attendants (TBAs) to hospital births. The women and their families both adapted to and shaped this transition through a constant ’trade-off between desirable and essential’- the desirable being a traditional homebirth in secure surroundings and the essential being the survival of mother and baby by going to hospital. This transition was shaped by complex multiple factors: 1) Overall economic growth and access to modern medical care influencing women’s choices, 2) External context in terms of the international maternal health discourses and national policies, especially incentive schemes for promoting institutional deliveries, 3) Socialisation into medical childbirth practices, through exposure to many years of free outreach services for maternal and child health, 4) Loss of self reliance in the community as a consequence of role redefinition and deskilling of the TBAs and 5) Cultural belief that intervention is necessary during childbirth aiding easy acceptance of medical interventions. Conclusion In resource poor settings where choices are

    An analytical ground vibration model is developed for study of the vibration effects on the beam motion in the Advanced Photon Source (APS) storage ring. The different physical parameters associated with the wave characteristics and the vibration modes needed for the study are taken from the vibration studies carried out at the APS site. The implementation has been carried out using Mathematica{trademark}. The study is carried out for the frequency range 1--35 Hz, with a number of sources changing from one through ten. The program written in Mathematica{trademark}, calculates orbit distortion, beta wave change, tune change, dispersion change, and chromaticity change. However, the main parameter studied for the APS storage ring has been the orbit distortion. The merit factor associated with different modes excited by the vibrations has been calculated.

    The REMS instrument, on board the Curiosity rover, has an infrared ground temperature sensor that allows monitoring the diurnal evolution of the ground temperature every day at the different sites visited by the rover during its operation on Gale crater. The amplitude of the diurnal ground temperature oscillation depends on the local column of dust, as well as on the thermal inertia (I) of the ground. The rover has a hot Radiosotope Thermal Generator (RTG) of which the temperature is monitored by engineering sensors. This element is an unavoidable extra source of heat that irradiates the ground where the rover stands. Whenever the rover moves and samples a new site the sensed temperature shows a significant drop that ranges between 3 and 15 K depending on the location and time of the day. This drop is the increment of temperature (ΔT) caused by the heat (q) emited by the RTG source alone, and thus the soil heat capacity (C) can be obtained by rating these magnitudes and allowing the rover to perform in situ ground calorimetry in a simple way: - The heat emited by the RTG can be evaluated using the Stefan Boltzman law (q=σT4) - The soil heat capacity scales with the square of the termal inertial ( C ~ I2) Orbitally determined inertias in the region of the rover [Fergason et al., 2012 ] range from 250 (J/m2K s1/2 ) to 410 (J/m2K s1/2). Thus in the area explored by the rover I may vary a factor 2, which leads to a factor 4 increment in C and thus the final ground offset induced by the RTG extra heating is expected to be significantly greater for soils of higher thermal inertia. Once the rover stands at a fixed position the ground is heated up as the ground responses in time to the irradiated heat until a new equilibrium temperature is reached. Soils with low thermal inertia respond faster to the RTG heating source (around 40 minutes) whereas high thermal inertia soils respond more slowly (around 75 minutes). This method shall be improved for future calorimetry

    2014-09-01

    Based on a modified grounded theory approach, in this study, we sought to elucidate the nursing care process used to guide psychiatric inpatients in long-term seclusion towards release from seclusion. Participant observations and interviews were conducted with a total of 18 nurses from three long-term psychiatric wards at two institutions from September 2011 to November 2012, to collect data on the nursing care they provided for psychiatric patients in long-term seclusion. Consequently, four categories and 15 concepts were extracted. The nurses viewed "a mature therapeutic environment that utilizes flexible apportionment of care" as the foundation (i.e. the core category) in guiding psychiatric inpatients towards release from long-term seclusion. The results revealed a care structure in which nurses in such a treatment environment provided care by flexible apportionment of three types of care: care aimed at avoiding mental and physical exhaustion, standardized care that does not confer a disadvantage to patients, and immediately responding to prevent problematic behaviors.

    A new method has been developed for the extraction of light filth from ground mace and ground caraway seed. The method uses a 2-step chloroform-isopropanol pretreatment followed by separation of the light filth from 40% isopropanol with mineral oil. The collaborative study resulted in clean filter papers with more reproducible recoveries of light filth elements than the official first action method, 44.116 (b). The method has been adopted as official first action. PMID:939749

    The activities undertaken by people suffering cancer and receiving oncology treatment are known to cause high levels of anxiety. In an oncology clinic in rural Australia, nurses and volunteers promoted the use of meditation to reduce the stress caused by the terminally associated illness and its treatments. The use and self-perceived effects of meditation by cancer sufferers and their partners was explored using a grounded theory approach. Data were gathered and analysed from a series of semi-structured interviews and the findings used to generate theory regarding the use of meditation within the oncology domain. A number of theories were generated by this data and they are discussed in relation to current nursing practice and future research.

    For Asian immigrants, immigration has the potential to disrupt all familiar routines. That is a threat to their health and well-being. This grounded theory study explored how immigrants adjust to a new environment by analyzing the experiences of 25 Korean immigrants in New Zealand. The findings suggest that immigration is a stress-inducing phenomenon that requires adjustment of valued activities and adversely affects their health. In response, participants worked on regaining control over disrupted activities by opting for two world perspectives. The study helps social workers to develop effective interventions and services for immigrants to better handle health problems.

    A detailed study of the various cosmological aspects in massive gravity theory has been presented in the present work. For the homogeneous and isotropic FLRW model, the deceleration parameter has been evaluated, and, it has been examined whether there is any transition from deceleration to acceleration in recent past, or not. With the proper choice of the free parameters, it has been shown that the massive gravity theory is equivalent to Einstein gravity with a modified Newtonian gravitational constant together with a negative cosmological constant. Also, in this context, it has been examined whether the emergent scenario is possible, or not, in massive gravity theory. Finally, we have done a cosmographic analysis in massive gravity theory.

  5. Study to eliminate ground resonance using active controls

    Straub, F. K.

    1984-01-01

    The effectiveness of active control blade feathering in increasing rotor body damping and the possibility to eliminate ground resonance instabilities were investigated. An analytical model representing rotor flapping and lead-lag degrees of freedom and body pitch, roll, longitudinal and lateral motion is developed. Active control blade feathering is implemented as state variable feedback through a conventional swashplate. The influence of various feedback states, feedback gain, and weighting between the cyclic controls is studied through stability and response analyses. It is shown that blade cyclic inplane motion, roll rate and roll acceleration feedback can add considerable damping to the system and eliminate ground resonance instabilities, which the feedback phase is also a powerful parameter, if chosen properly, it maximizes augmentation of the inherent regressing lag mode damping. It is shown that rotor configuration parameters, like blade root hinge offset, flapping stiffness, and precone considerably influence the control effectiveness. It is found that active control is particularly powerful for hingeless and bearingless rotor systems.

  6. Statistical Studies of Ground-Based Optical Lightning Signatures

    2005-12-01

    Most extensive optical studies of lightning have been conducted from orbit, and the statistics of events collected from earth are relatively poorly documented. The time signatures of optical power measured in the presence of clouds are inevitably affected by scattering,which can distort the signatures by extending and delaying the amplitude profile in time. We have deployed two all-sky photodiode detectors, one in New Mexico and one in Oklahoma, which are gathering data alongside electric field change monitors as part of the LANL EDOTX Great Plains Array. Preliminary results show that the photodiode is sensitive to approximately 50% or more of RF events detected at ranges of up to 30 km, and still has some sensitivity at ranges in excess of 60 km (distances determined by the EDOTX field-change array). The shapes of events within this range were assessed, with focus on rise time, width, peak power, and their correlation to corresponding electric field signatures, and these are being compared with published on-orbit and ground-based data. Initial findings suggest a mean characteristic width (ratio of total detected optical energy to peak power) of 291 +/- 12 microseconds and a mean delay between the RF signal peak and optical peak of 121 +/- 17 microseconds. These values fall between prior ground-based measurements of direct return stroke emissions, and scattering-dominated on-orbit measurements. This work will promote better understanding of the correspondence between radio and optical measurements of lightning.

  7. Application of ground-penetrating-radar methods in hydrogeologic studies

    Beres, Milan; Haeni, F.P.

    1991-01-01

    A ground-penetrating-radar system was used to study selected stratified-drift deposits in Connecticut. Ground-penetrating radar is a surface-geophysical method that depends on the emission, transmission, reflection, and reception of an electromagnetic pulse and can produce continuous high-resolution profiles of the subsurface rapidly and efficiently. Traverse locations on land included a well field in the town of Mansfield, a sand and gravel pit and a farm overlying a potential aquifer in the town of Coventry, and Haddam Meadows State Park in the town of Haddam. Traverse locations on water included the Willimantic River in Coventry and Mansfield Hollow Lake in Mansfield. The penetration depth of the radar signal ranged from about 20 feet in fine-grained glaciolacustrine sediments to about 70 feet in coarse sand and gravel. Some land records in coarse-grained sediments show a distinct, continuous reflection from the water table about 5 to 11 feet below land surface. Parallel reflectors on the records are interpreted as fine-grained sediments. Hummocky or chaotic reflectors are interpreted as cross-bedded or coarse-grained sediments. Other features observed on some of the radar records include the till and bedrock surface. Records collected on water had distinct water-bottom multiples (more than one reflection) and diffraction patterns from boulders. The interpretation of the radar records, which required little or no processing, was verified by using lithologic logs from test holes located along some of the land traverses and near the water traverses.

  8. Grounding a theory of African migration in recent data on Ghana.

    PubMed

    Achanfuo-yeboah, D

    1993-06-01

    This article discusses the development of a single theory of migration in Africa, which accounts for social, economic, cultural, psychological, and demographic factors. Prior migration literature refers to many countries in Africa. The empirical test in this paper is based on Ghana and data for 1960, 1970, and 1984. Ghana is described as having rapid population growth and urbanization reaching 12.5 million in 1984. The economy is based on agriculture, mining, and manufacturing. Education is available for free through the secondary school level (since 1965). The general theory of migration holds that the nature, intensity, direction, and patterns of migration are shaped by social, cultural, economic, and political developments. Sociocultural developments, or nonagricultural occupations and educational resources, may influence the flow of migration to urban areas. The regression model shows that 70% of the variance in net migration is explained by education, economic activity, and population growth. Education determines the direction and intensity of migration. A unit value of education causes a change of 0.251952 in the value of net migration. Norms, values, and beliefs are affected by educational and employment opportunities and are influenced by factors such as kinship, clan, language, beliefs, and religion. Economic infrastructure, industrialization, employment opportunities, and increased wages and salaries exert a pull on migrants. During the 1960s, Ghana attracted migrants from Nigeria. During the 1970s and 1980s, the reverse occurred. Migrants tend to move based on expectations of higher wages and better employment. In a bivariate relationship, economic activity explains 62% of the variance in migration. A unit change in the value of economic activity leads to a change of 1.379382 in the value of net migration. The literature emphasizes rural-urban flows, but migration in Gwan state in Cameroon and Udo state in Nigeria reflects the prevalence of rural

  9. Ground Operations Aerospace Language (GOAL). Volume 5: Application Studies

    NASA Technical Reports Server (NTRS)

    1973-01-01

    The Ground Operations Aerospace Language (GOAL) was designed to be used by test oriented personnel to write procedures which would be executed in a test environment. A series of discussions between NASA LV-CAP personnel and IBM resulted in some peripheral tasks which would aid in evaluating the applicability of the language in this environment, and provide enhancement for future applications. The results of these tasks are contained within this volume. The GOAL vocabulary provides a high degree of readability and retainability. To achieve these benefits, however, the procedure writer utilizes words and phrases of considerable length. Brief form study was undertaken to determine a means of relieving this burden. The study resulted in a version of GOAL which enables the writer to develop a dialect suitable to his needs and satisfy the syntax equations. The output of the compiler would continue to provide readability by printing out the standard GOAL language. This task is described.

    2006-03-01

    The aim of this study was to develop a model of mental health professional (MHP) support based on the needs of families with a member suffering from severe mental illness (SMI). Twelve family members were interviewed with the focus on their needs of support by MHP, then the interviews were analyzed according to the grounded theory method. The generated model of MHP support had two core categories: the family members' process from crisis to recovery and their interaction with the MHP about mental health/illness and daily living of the person with SMI. Interaction based on ongoing contact between MHP and family members influenced the family members' process from crisis towards recovery. Four MHP strategies--being present, listening, sharing and empowering--met the family members' needs of support in the different stages of the crisis. Being present includes early contact, early information and protection by MHP at onset of illness or relapse. Listening includes assessing burden, maintaining contact and confirmation in daily living for the person with SMI. Sharing between MHP and family members includes co-ordination, open communication and security in daily living for the person with SMI. Finally, the MHP strategy empowering includes creating a context, counselling and encouraging development for the family members. The present model has a holistic approach and can be used as an overall guide for MHP support in clinical care of families of persons with SMI. For future studies, it is important to study the interaction of the family with SMI and the connection between hope, coping and empowerment.

    There are many ways to categorise conspiracy theories. In the present study, we examined individual and demographic predictors of beliefs in commercial conspiracy theories among a British sample of over 300 women and men. Results showed many people were cynical and sceptical with regard to advertising tricks, as well as the tactics of organisations like banks and alcohol, drug and tobacco companies. Beliefs sorted into four identifiable clusters, labelled sneakiness, manipulative, change-the-rules and suppression/prevention. The high alpha for the overall scale suggested general beliefs in commercial conspiracy. Regressions suggested that those people who were less religious, more left-wing, more pessimistic, less (self-defined as) wealthy, less Neurotic and less Open-to-Experience believed there was more commercial conspiracy. Overall the individual difference variables explained relatively little of the variance in these beliefs. The implications of these findings for the literature on conspiracy theories are discussed. Limitations of the study are also discussed. PMID:23818886

    The Gaoliying ground fissure in Beijing has caused building cracking and road damage, and has seriously influenced city construction. Based on investigations and trenching, the influences of the fault and the variation of groundwater levels on the formation mechanism of the Gaoliying ground fissure were investigated by using FLAC3D. The results indicated that (1) the surface location of Gaoliying fissure is controlled by the underlying normal fault activity, and over pumping further exacerbates development of the ground fissure; (2) when the groundwater level declines, obvious differential settlement occurs at both sides of the ground fissure, in which greater settlement occurs in the vicinity of the hanging wall, the greater the distance from the hanging wall, the smaller the ground subsidence, however smaller ground subsidence occurs in the vicinity of the footwall, the greater the distance from the footwall, the greater the ground subsidence; (3) the vertical velocity of the ground fissure triggered by the fault activity and groundwater decline ranges from 15.5 to 18.3 mm a-1, which is basically in line with the monitoring data. The fault activity contributes about 28-39 %, and the groundwater contributes about 61-72 % to the deformation of the ground fissure, respectively.

    The official method for extracting light filth from ground nutmeg, 44.116, gives variable recoveries of filth elements and results in large amounts of interfering plant material in the light filth extraction. A new method has been developed using a chloroform pretreatment for heavy filth followed by a water-40% isopropanol-mineral oil flotation of light filth. A comparison of the methods in the collaborative study showed a higher recovery of insect fragments, 90.6 vs. 65.2%, and of rodent hairs, 86.5 vs. 66.5%, for the new method over the present official first action method, 44.116. Frothing, an additional problem with the official method, has been reduced by the new method. The new method has been adopted as official first action to replace the existing method. PMID:573260

    Ground-based studies of soot processes in laminar flames proceeded in two phases, considering laminar premixed flames and laminar diffusion flames, in turn. The test arrangement for laminar premixed flames involved round flat flame burners directed vertically upward at atmospheric pressure. The test arrangement for laminar jet diffusion flames involved a round fuel port directed vertically upward with various hydrocarbon fuels burning at atmospheric pressure in air. In both cases, coflow was used to prevent flame oscillations and measurements were limited to the flame axes. The measurements were sufficient to resolve soot nucleation, growth and oxidation rates, as well as the properties of the environment needed to evaluate mechanisms of these processes. The experimental methods used were also designed to maintain capabilities for experimental methods used in corresponding space-based experiments. This section of the report will be limited to consideration of flame structure for both premixed and diffusion flames.

    Variations in health between neighborhoods are well known and the conceptualization of social capital has contributed to an understanding of how contextual factors influence these differences. Studies show positive health-effects from living in high social capital areas, at least for some population sub-groups. The aim of this qualitative study was to understand what constitutes a 'health-enabling' neighborhood. It follows up results from a social capital survey in northern Sweden indicating that the health effects of living in a high social capital neighborhood is gendered in favor of women. A grounded theory situational analysis of eight focus group discussions--four with men and four with women--illustrated similar and different positions on how neighborhood characteristics influence health. A neighborhood, where people say hi to each other ("hi-factor") and where support between neighbors exist, were factors perceived as positive for health by all, as was a good location, neighborhood greenness and proximity to essential arenas. Women perceived freedom from demands, feeling safe and city life as additional health enabling factors. For men freedom to do what you want, a sense of belonging, and countryside life were important. To have burdensome neighbors, physical disturbances and a densely living environment were perceived as negative for health in both groups while demands for a well styled home and feeling unsafe were perceived as negative for health among women. Neighborhood social capital, together with other elements in the living environment, has fundamental influence on people's perceived health. Our findings do not confirm that social capital is more important for women than for men but that distinctive form of social capital differ in impact.

    2015-01-01

    Female veterans, the fastest growing segment in the military, have unique pre-military histories and military experiences that are associated with post-military physical and mental health service needs. Successful treatment is contingent on a clearer understanding of the processes underlying these experiences. Data from 20 female veterans who served post–Gulf War were analyzed to generate a substantive theory of the process of women who entered, served in, and transitioned out of the military. Coping with transitions emerged as the basic psychosocial process used by female veterans. The Coping with transitions process is comprised of seven categories: Choosing the Military, Adapting to the Military, Being in the Military, Being a Female in the Military, Departing the Military, Experiencing Stressors of Being a Civilian, and Making Meaning of Being a Veteran-Civilian. The results of this study provide a theoretical description of the process female veterans experience when transitioning from a civilian identity, through military life stressors and adaptations, toward gaining a dual identity of being a veteran-civilian.

This article describes the ongoing development of a theory that can assist in explaining experiences of young women with breast cancer who have genetic testing for the BRCA mutation. Seventeen BRCA-negative women with breast cancer from a larger grounded theory study were interviewed. While receiving a negative BRCA mutation test result subsequent to a breast cancer diagnosis was described as a relief, the information was also confusing. The author's published Theory of Genetic Vulnerability is expanded to incorporate the outcomes of this analysis.

    Laminar diffusion flames are of interest because they provide model flame systems that are far more tractable for analysis and experiments than more practical turbulent diffusion flames. Certainly, understanding flame processes within laminar diffusion flames must precede understanding these processes in more complex turbulent diffusion flames. In addition, many properties of laminar diffusion flames are directly relevant to turbulent diffusion flames using laminar flamelet concepts. Laminar jet diffusion flame shapes (luminous flame boundaries) have been of particular interest since the classical study of Burke and Schumann because they are a simple nonintrusive measurement that is convenient for evaluating flame structure predictions. Thus, consideration of laminar flame shapes is undertaken in the following, emphasizing conditions where effects of gravity are small, due to the importance of such conditions to practical applications. Another class of interesting properties of laminar diffusion flames are their laminar soot and smoke point properties (i.e., the flame length, fuel flow rate, characteristic residence time, etc., at the onset of soot appearance in the flame (the soot point) and the onset of soot emissions from the flame (the smoke point)). These are useful observable soot properties of nonpremixed flames because they provide a convenient means to rate several aspects of flame sooting properties: the relative propensity of various fuels to produce soot in flames; the relative effects of fuel structure, fuel dilution, flame temperature and ambient pressure on the soot appearance and emission properties of flames; the relative levels of continuum radiation from soot in flames; and effects of the intrusion of gravity (or buoyant motion) on emissions of soot from flames. An important motivation to define conditions for soot emissions is that observations of laminar jet diffusion flames in critical environments, e.g., space shuttle and space station

    The ground-state electronic configurations of the correlated organometallic metallocenes, M Cp2,M =V , Cr, Mn, Fe, Co, and Ni, are investigated using constraint density functional theory combined with nonempirical Ueff parameters determined from linear-response theory. The relative stability of the various d -orbital electronic configurations of these organometallic molecules is found to be sensitive to the amount of correlation. Using nonempirical values of Ueff, the calculated electronic configurations are in agreement with the experiments: 4A2 g ,3E2 g ,6A1 g ,1A1 g ,2E1 g , and 3A2 g for the VCp2,CrCp2,MnCp2,FeCp2,CoCp2 , and NiCp2, respectively.

    The electronic structure of a diiron (FeFe) complex with strong metal-metal interaction and those of analogous complexes (CoCo, CoMn, CoFe, and FeMn) with much weaker metal-metal bonding are investigated with wave function-based methods and density functional theory. The delocalization and bonding between the metal centers in the diiron complex is only fully captured after inclusion of the complete set of 3d and 4d orbitals in the active space, a situation best suited for restricted active space (RAS) approaches. Truncation of the included set of 4d orbitals results in inappropriate localization of some 3d orbitals, incorrect description of the ground spin state as well as wrong spin state energetics, as compared to experiment. Using density functional theory, some local functionals are able to predict the correct ground spin states, and describe the chemical bonding and structural properties of all the metal-metal complexes considered in this work. In contrast, the introduction of some exact exchange results in increased localization of 3d orbitals and wrong spin state energetics, a situation that is particularly troublesome for the diiron complex.

The scientific effort is principally on the thermal and the fluid phenomena associated with the local heating of levitated drops, both at 1-g and at low-g. In particular, the thermocapillary flow associated with local spot heating is being studied. Fairly stable acoustic levitation of drops has been achieved with some exceptions when random rotational motion of the drop persists. The flow visualization has been carried out by light scattering from smoke particles for the exterior flow and fluorescent tracer particles in the drop. The results indicate a lack of axial symmetry in the internal flow even though the apparatus and the heating are symmetric. The theoretical studies for the past year have included fundamental analyses of acoustically levitated spherical drops. The flow associated with a particle near the velocity antinode is being investigated by the singular perturbation technique. As a first step towards understanding the effect of the particle displacement from the antinode, the flow field about the node has been calculated for the first time. The effect of the acoustic field on the interior of a liquid drop has also been investigated. The results predict that the internal flow field is very weak.

  8. Identifying the unique ground motion signatures of supershear earthquakes: Theory and experiments

    2010-10-01

    The near field ground motion signatures associated with sub-Rayleigh and supershear ruptures are investigated using the laboratory earthquake experiment originally developed by Rosakis and coworkers (Xia et al., 2004, 2005a; Lu et al., 2007; Rosakis et al., 2007). Heterodyne laser interferometers enable continuous, high bandwidth measurements of fault-normal (FN) and fault-parallel (FP) particle velocity "ground motion" records at discrete locations on the surface of a Homalite test specimen as a sub-Rayleigh or a supershear rupture sweeps along the frictional fault. Photoelastic interference fringes, acquired using high-speed digital photography, provide a synchronized, spatially resolved, whole field view of the advancing rupture tip and surrounding maximum shear stress field. Experimental results confirm that near field ground motion records associated with the passage of a sub-Rayleigh rupture are characterized by a FN velocity swing which dominates over the FP velocity swing. The situation is shown to reverse in the supershear rupture speed regime whereby the motion along the shear Mach front is characterized by a FP particle velocity swing which dominates over the FN velocity swing. Additional distinguishing particle velocity signatures, consistent with theoretical and numerical predictions, and repeatedly observed in experimental records are (1) a pronounced peak in the FP velocity record, induced by the leading dilatational field, which sweeps the measurement station just prior to the arrival of the shear Mach front, and (2) a pronounced velocity swing in the FN record associated with the arrival of a "trailing Rayleigh disturbance", which sweeps the measurement station following passage of the shear Mach front. Each of these features are addressed in detail. We conclude by reexamining the 2002, Mw7.9 Denali fault earthquake and the remarkable set of ground motion records obtained at Pump Station 10 (PS10), located approximately 85 km east of the epicenter

    2012-07-01

    The molecular properties of the ground state and some low-lying excited states of the yttrium monohalides, YX (X = F, Cl, Br, and I), have been calculated using the B3P86 method of density functional theory (DFT). For each state, the equilibrium bond lengths of re , the harmonic vibrational frequencies of ωe , the dissociation energies of D0 , the term values of Te , the dipole moments of μ, for all the yttrium monohalides were obtained analytically and compared with the experimental and other theoretical values. Compared with the experimental results, the hybrid density functional B3P86 is superior to or comparable with the other theoretical results and predicts well all the spectroscopic parameters such as equilibrium bond lengths and the harmonic vibrational frequencies, but underestimates the term values. By comparing the computed results for B3P86 and CCSD(T), a reasonable explanation has been given for the discrepancy between the computed and experimental term values of YX. In addition, the effect of the halogens on the spectroscopic parameters for the group of YX has been discussed with the help of the molecular orbital diagram.

    This report documents the Government Applications Task Force (GATF) Buried Waste Project. The project was initiated as a field investigation and verification of the 1994 Strategic Environmental Research and Development Program`s (SERDP) Buried Waste Identification Project results. The GATF project team included staff from three US Department of Energy (DOE) Laboratories [Oak Ridge National Laboratory (ORNL), Los Alamos National Laboratory (LANL), and the Savannah River Technology Center (SRTC)] and from the National Exploitation Laboratory. Similar studies were conducted at each of the three DOE laboratories to demonstrate the effective use of remote sensing technologies. The three locations were selected to assess differences in buried waste signatures under various environmental conditions (i.e., climate, terrain, precipitation, geology, etc.). After a brief background discussion of the SERDP Project, this report documents the field investigation (ground truth) results from the 1994--1995 GATF Buried Waste Study at ORNL`s Waste Area Grouping (WAG) 4.

  15. Identifying the Unique Ground Motion Signatures of Supershear Earthquakes: Theory and Experiments

    NASA Astrophysics Data System (ADS)

    Mello, Michael

    The near-field ground motion signatures associated with sub-Rayleigh and supershear ruptures are investigated using the laboratory earthquake experiment originally developed by Rosakis and co-workers (Xia et al., 2004, 2005; Lu et al., 2007; Rosakis et al., 2007). Heterodyne laser interferometers enable continuous, high-bandwidth measurements of fault-normal (FN), fault-parallel (FP), and vertical (V) particle velocity ``ground motion" records at discrete locations on the surface of a Homalite-100 test specimen as a sub-Rayleigh or a supershear rupture sweeps along the frictional fault. Photoelastic interference fringes, acquired using high-speed digital photography, provide a synchronized, spatially resolved, whole field view of the advancing rupture tip and surrounding maximum shear stress field. The first phase of experimental investigations examine and verify the ground motion signatures of supershear ruptures. Experimental results demonstrate that a shear Mach front produced by a stable supershear rupture is characterized by a dominant FP velocity component. The situation is shown to reverse in the sub-Rayleigh rupture speed regime whereby the FN particle velocity component dominates the ground motion record. Additional distinguishing particle velocity signatures, consistent with theoretical and numerical predictions, and repeatedly observed in experimental records are, (1) a pronounced peak in the FP velocity record induced by the leading dilatational field, which sweeps the measurement station in advance of the shear Mach front, and (2) a pronounced velocity swing in the FN record associated with the arrival of a trailing Rayleigh sub-Rayleigh (secondary) rupture, which follows the arrival of the shear Mach front. Analysis of the particle velocity records also confirms 2D steady-state theoretical predictions pertaining to the separation, attenuation, and radiation partitioning of the shear and dilatational portions of the rupture velocity field components

    2015-12-01

    Data from three-dimensional VHF mapping, high-speed video and slow electric field antenna of multiple ground contact flashes (MGCFs) have been analyzed in an attempt to characterize the process through which new ground terminations in natural lightning are formed. The three-dimensional VHF mapping data (obtained by a Lightning Mapping Array, LMA) provided valuable information on the processes that occurred inside the cloud during the interval between strokes. Detailed case studies of over 30 MGCFs observed in the vicinity of a wind farm in Kansas, USA, have allowed the identification and qualitative description of three mechanisms through which a given flash may touch ground at different locations. In events of Type I, the dart leader that initiates the subsequent stroke starts in the original channel and then diverges from the original path of the first stroke, ionizing a new channel and reaching ground at a different location. In high-speed video records, these events eventually have their "diverging" point visible below cloud base and their strike locations are separated by a few hundreds of meters. Type II, on the other hand, comprises flashes in which the subsequent stroke is initiated in an in-cloud branch that is farther from the inception region of the first return stroke, moving in another direction and touching ground at farther distances (up to more than 10 km from the initial strike location). Finally, Type III flashes typically gave rise to several return strokes, each with different ground strike points. Stepped leaders initiated in the same general region in the cloud give rise to these strokes with typical interstroke intervals below 100 milliseconds but no common channel branches among them could be conclusively identified. Representative events of each type are discussed in detail.

  1. Grounding Cognitive-Level Processes in Behavior: The View from Dynamic Systems Theory

    PubMed Central

    Samuelson, Larissa K.; Jenkins, Gavin W.; Spencer, John P.

    2015-01-01

    Marr’s seminal work laid out a program of research by specifying key questions for cognitive science at different levels of analysis. Because Dynamic Systems Theory focuses on time and interdependence of components DST research programs come to very different conclusions regarding the nature of cognitive change. We review a specific DST approach to cognitive-level processes: Dynamic Field Theory. We review research applying dynamic field theory to several cognitive-level processes: object permanence, naming hierarchical categories, and inferring intent, that demonstrate the difference in understanding of behavior and cognition that results from a DST perspective. These point to a central challenge for cognitive science research as defined by Marr—emergence. We argue that appreciating emergence raises questions about the utility of computational level analyses and opens the door to insights concerning the origin of novel forms of behavior and thought (e.g., a new chess strategy). We contend this is one of the most fundamental questions about cognition and behavior. PMID:25755203

  2. Selection of Treatment Strategies among Patients with Type 2 Diabetes Mellitus in Malaysia: A Grounded Theory Approach

    PubMed Central

    Low, Lee Lan; Tong, Seng Fah; Low, Wah Yun

    2016-01-01

    Background Diabetes Mellitus is a multifaceted chronic illness and its life-long treatment process requires patients to continuously engage with the healthcare system. The understanding of how patients manoeuvre through the healthcare system for treatment is crucial in assisting them to optimise their disease management. This study aims to explore issues determining patients’ treatment strategies and the process of patients manoeuvring through the current healthcare system in selecting their choice of treatment for T2DM. Methods The Grounded Theory methodology was used. Twelve patients with Type 2 Diabetes Mellitus, nine family members and five healthcare providers from the primary care clinics were interviewed using a semi-structured interview guide. Three focus group discussions were conducted among thirteen healthcare providers from public primary care clinics. Both purposive and theoretical samplings were used for data collection. The interviews were audio-taped and transcribed verbatim, followed by line-by-line coding and constant comparison to identify the categories and core category. Results The concept of “experimentation” was observed in patients’ help-seeking behaviour. The “experimentation” process required triggers, followed by information seeking related to treatment characteristics from trusted family members, friends and healthcare providers to enable decisions to be made on the choice of treatment modalities. The whole process was dynamic and iterative through interaction with the healthcare system. The decision-making process in choosing the types of treatment was complex with an element of trial-and-error. The anchor of this process was the desire to fulfil the patient’s expected outcome. Conclusion Patients with Type 2 Diabetes Mellitus continuously used “experimentation” in their treatment strategies and help-seeking process. The “experimentation” process was experiential, with continuous evaluation, information seeking

    2014-10-15

    The rare-earth metals have important technological applications due to their magnetic properties, but are scarce and expensive. Development of high-performance magnetic materials with less rare-earth content is desired, but theoretical modeling is hampered by complexities of the rare earths electronic structure. The existence of correlated (atomic-like) 4f electrons in the vicinity of the valence band makes any first-principles theory challenging. Here, we apply and evaluate the efficacy of density-functional theory for the series of lanthanides (rare earths), investigating the influence of the electron exchange and correlation functional, spin-orbit interaction, and orbital polarization. As a reference, the results are compared with those of the so-called 'standard model' of the lanthanides in which electrons are constrained to occupy 4f core states with no hybridization with the valence electrons. Some comparisons are also made with models designed for strong electron correlations. Our results suggest that spin-orbit coupling and orbital polarization are important, particularly for the magnitude of the magnetic moments, and that calculated equilibrium volumes, bulk moduli, and magnetic moments show correct trends overall. However, the precision of the calculated properties is not at the level of that found for simpler metals in the Periodic Table of Elements, and the electronic structures do not accurately reproduce x-ray photoemission spectra.

    Building upon the numerous successes of the pre-solar maximum International Solar Terrestrial Physics (ISTP) mission, the ISTP Solar Maximum Mission is expected to produce new insights into global flow of energy, momentum, and mass, from the Sun, through the heliosphere, into the magnetosphere and to their final deposition in the terrestrial upper atmosphere/ionosphere system. Of particular interest is the determination of the geo-effectiveness of solar events, principally Coronal Mass Ejections (CMEs). Given the expected increased frequency and strength of CMEs during the Solar Maximum period, a major advance in our understanding of nature of the coupling of CMEs to the magnetosphere-ionosphere-atmosphere system is expected. The roles during this time of the various ISTP assets will be discussed. These assets will include the SOHO, Wind, Polar, and Geotail spacecraft, the ground-based observing networks and the theory tools.

    Interprofessional care (IPC) is a prerequisite for enhanced communication between healthcare team members, improved quality of care, and better outcomes for patients. A move to an IPC model requires changing the learning experiences of healthcare providers during and after their qualification program. With the rapid growth of online and blended approaches to learning, an educational framework that explains how to construct quality learning events to provide IPC is pressing. Such a framework would offer a quality standard to help educators design, develop, deliver, and evaluate online interprofessional education (IPE) programs. IPE is an extremely delicate process due to issues related to knowledge, status, power, accountability, personality traits, and culture that surround IPC. In this paper, a review of the pertinent literature that would inform the development of such a framework is presented. The review covers IPC, IPE, learning theories, and eLearning in healthcare.

  8. Theoretical study of the effect of ground proximity on the induced efficiency of helicopter rotors

    NASA Technical Reports Server (NTRS)

    Heyson, H. H.

    1977-01-01

    A study of rotors in forward flight within ground effect showed that the ground-induced interference is an upwash and a decrease in forward velocity. The interference velocities are large, oppose the normal flow through the rotor, and have large effects on the induced efficiency. Hovering with small ground clearances may result in significant blade stall. As speed is increased from hover in ground effect, power initially increases rather than decreases. At very low heights above the ground, the power requirements become nonlinear with speed as a result of the streamwise interference. The streamwise interference becomes greater as the wake approaches the ground and eventually distorts the wake to form the ground vortex which contributes to certain observed directional stability problems.

    The Building 103 Dump is one of ten potentially contaminated sites in the Canal Creek and Westwood areas of the Edgewood section of Aberdeen Proving Ground examined by a geophysical team from Argonne National Laboratory in April and May of 1992. Noninvasive geophysical surveys, including magnetics, resistivity, ground-penetrating radar, and seismic refraction, were conducted. These surveys indicate that much of the area is free of debris. However, prominent magnetic and resistivity anomalies occur along well-defined lineaments, suggestive of a dendritic stream pattern. Prior to the onset of dumping, the site was described as a ``sand pit,`` which suggests that headward erosion of Canal Creek tributaries cut into the surficial aquifer. Contaminants dumped into the landfill would have direct access to the surficial aquifer and thus to Canal Creek. Seismic refraction profiling indicates 6--12 ft of fill material now rests on the former land surface. Only the northern third of the former landfill was geophysically surveyed.

    Results are presented of an experimental investigation made of the applied ground loads and the coefficient of friction between the tire and the ground during the wheel spin-up process in impacts of a small landing gear under controlled conditions on a concrete landing strip in the Langley impact basin. The basic investigation included three major phases: impacts with forward speed at horizontal velocities up to approximately 86 feet per second, impacts with forward speed and reverse wheel rotation to simulate horizontal velocities up to about 273 feet per second, and spin-up drop tests for comparison with the other tests. In addition to the basic investigation, supplementary tests were made to evaluate the drag-load alleviating effects of prerotating the wheel before impact so as to reduce the relative velocity between the tire and ground. In the presentation of the results, an attempt has been made to interpret the experimental data so as to obtain some insight into the physical phenomena involved in the wheel spin-up process.

  11. Studying ground water under Delmarva coastal bays using electrical resistivity

    Manheim, Frank T.; Krantz, David E.; Bratton, John F.

    2004-01-01

    Fresh ground water is widely distributed in subsurface sediments below the coastal bays of the Delmarva Peninsula (Delaware, Maryland, and Virginia). These conditions were revealed by nearly 300 km of streamer resistivity surveys, utilizing a towed multichannel cable system. Zones of high resistivity displayed by inversion modeling were confirmed by vibradrilling investigations to correspond to fresh ground water occurrences. Fresh water lenses extended from a few hundred meters up to 2 km from shore. Along the western margins of coastal bays in areas associated with fine-grained surficial sediments, high-resistivity layers were widespread and were especially pronounced near tidal creeks. Fresh ground water layers were less common along the eastern barrier-bar margins of the bays, where sediments were typically sandy. Mid-bay areas in Chincoteague Bay, Maryland, did not show evidence of fresh water. Indian River Bay, Delaware, showed complex subsurface salinity relationships, including an area with possible hypersaline brines. The new streamer resistivity system paired with vibradrilling in these investigations provides a powerful approach to recovering information required for extension of hydrologic modeling of shallow coastal aquifer systems into offshore areas.

    Many models used to represent the boundary condition for the separation of atmospheric scattering from the surface reflectance in polarized remote sensing measurements assume that the polarized surface reflectance is spectrally neutral. The Spectral Invariance Hypothesis asserts that the magnitude and shape of the polarized bidirectional reflectance factor (pBRF) is equal for all wavelengths. In order to test this hypothesis, JPL's Ground-based Multiangle SpectroPolarimetric Imager (GroundMSPI) is used to measure polarization information of different outdoor surface types. GroundMSPI measures the linear polarization Stokes parameters (I, Q, U), at three wavelengths, 470 nm, 660 nm, and 865 nm. The camera is mounted on a two-axis gimbal to accurately select the view azimuth and elevation directions. On clear sky days we acquired day-long scans of scenes that contain various surface types such as grass, dirt, cement, brick, and asphalt and placed a Spectralon panel in the camera field of view to provide a reflectance reference. Over the course of each day, changing solar position in the sky provides a large range of scattering angles for this study. The polarized bidirectional reflectance factor (pBRF) is measured for the three wavelengths and the best fit slope of the spectral correlation is reported. This work reports the range of best fit slopes measured for five region types.

    2008-01-01

    Grounded cognition rejects traditional views that cognition is computation on amodal symbols in a modular system, independent of the brain's modal systems for perception, action, and introspection. Instead, grounded cognition proposes that modal simulations, bodily states, and situated action underlie cognition. Accumulating behavioral and neural evidence supporting this view is reviewed from research on perception, memory, knowledge, language, thought, social cognition, and development. Theories of grounded cognition are also reviewed, as are origins of the area and common misperceptions of it. Theoretical, empirical, and methodological issues are raised whose future treatment is likely to affect the growth and impact of grounded cognition.

    During lunar excursions in the EVA suit, real-time measurement of metabolic rate is required to manage consumables and guide activities to ensure safe return to the base. Metabolic rate, or oxygen consumption (VO2), is normally measured from pulmonary parameters but cannot be determined with standard techniques in the oxygen-rich environment of a spacesuit. Our group has developed novel near infrared spectroscopic (NIRS) methods to calculate muscle oxygen saturation (SmO 2), hematocrit, and pH, and we recently demonstrated that we can use our NIRS sensor to measure VO 2 on the leg during cycling. Our NSBRI project has 4 objectives: (1) increase the accuracy of the metabolic rate calculation through improved prediction of stroke volume; (2) investigate the relative contributions of calf and thigh oxygen consumption to metabolic rate calculation for walking and running; (3) demonstrate that the NIRS-based noninvasive metabolic rate methodology is sensitive enough to detect decrement in VO 2 in a space analog; and (4) improve instrumentation to allow testing within a spacesuit. Over the past year we have made progress on all four objectives, but the most significant progress was made in improving the instrumentation. The NIRS system currently in use at JSC is based on fiber optics technology. Optical fiber bundles are used to deliver light from a light source in the monitor to the patient, and light reflected back from the patient s muscle to the monitor for spectroscopic analysis. The fiber optic cables are large and fragile, and there is no way to get them in and out of the test spacesuit used for ground-based studies. With complimentary funding from the US Army, we undertook a complete redesign of the sensor and control electronics to build a novel system small enough to be used within the spacesuit and portable enough to be used by a combat medic. In the new system the filament lamp used in the fiber optic system was replaced with a novel broadband near infrared

    Aim This study aims at exploring the main concern for elderly individuals with somatic health problems and what they do to manage this. Method In total, 14 individuals (mean=74.2 years; range=68–86 years) of both gender including hospitalized and outpatient persons participated in the study. Open interviews were conducted and analyzed according to grounded theory, an inductive theory-generating method. Results The main concern for the elderly individuals with somatic health problems was identified as their striving to maintain control and balance in life. The analysis ended up in a substantive theory explaining how elderly individuals with somatic disease were calibrating and adjusting their expectations in life in order to adapt to their reduced energy level, health problems, and aging. By adjusting the expectations to their actual abilities, the elderly can maintain a sense of that they still have the control over their lives and create stability. The ongoing adjustment process is facilitated by different strategies and result despite lower expectations in subjective well-being. The facilitating strategies are utilizing the network of important others, enjoying cultural heritage, being occupied with interests, having a mission to fulfill, improving the situation by limiting boundaries and, finally, creating meaning in everyday life. Conclusion The main concern of the elderly with somatic health problems was to maintain control and balance in life. The emerging theory explains how elderly people with somatic health problems calibrate their expectations of life in order to adjust to reduced energy, health problems, and aging. This process is facilitated by different strategies and result despite lower expectation in subjective well-being. PMID:21468299

    2005-01-01

    Ground water can facilitate earthquake development and respond physically and chemically to tectonism. Thus, an understanding of ground water circulation in seismically active regions is important for earthquake prediction. To investigate the roles of ground water in the development and prediction of earthquakes, geological and hydrogeological monitoring was conducted in a seismogenic area in the Yanhuai Basin, China. This study used isotopic and hydrogeochemical methods to characterize ground water samples from six hot springs and two cold springs. The hydrochemical data and associated geological and geophysical data were used to identify possible relations between ground water circulation and seismically active structural features. The data for ??18O, ??D, tritium, and 14C indicate ground water from hot springs is of meteoric origin with subsurface residence times of 50 to 30,320 years. The reservoir temperature and circulation depths of the hot ground water are 57??C to 160??C and 1600 to 5000 m, respectively, as estimated by quartz and chalcedony geothermometers and the geothermal gradient. Various possible origins of noble gases dissolved in the ground water also were evaluated, indicating mantle and deep crust sources consistent with tectonically active segments. A hard intercalated stratum, where small to moderate earthquakes frequently originate, is present between a deep (10 to 20 km), high-electrical conductivity layer and the zone of active ground water circulation. The ground water anomalies are closely related to the structural peculiarity of each monitoring point. These results could have implications for ground water and seismic studies in other seismogenic areas. Copyright ?? 2005 National Ground Water Association.

  15. Density-matrix theory for the ground state of spin-compensated harmonically confined two-electron model atoms with general interparticle repulsion

    NASA Astrophysics Data System (ADS)

    Akbari, Ali; March, Norman H.; Rubio, Angel

    2009-09-01

    For model two-electron atoms with harmonic confinement, the correlated first-order density matrix can be expressed in terms of the relative motion wave function ΨR(r) . Here we demonstrate that the probability density P(r) associated with this wave function is directly related to the x-ray scattering factor f(G) . This latter quantity, in turn, is determined by the ground-state electron density n(r) . The Euler-Lagrange equation of the resulting density-matrix theory is thereby shown to take the form of a third-order integro-differential equation for n(r) in which the probability density P(r)=ΨR2(r) also appears. For two specific choices of the interaction between the two fermions under consideration, the above integro-differential equation derived here is shown to lead back to known linear homogeneous differential equations for the electron density. Finally, it is emphasized that specific equations summarized here will apply directly to theoretical study of the nonrelativistic ground-state electron density n(r,Z) in the He-like ions with atomic number Z .

    Vanderarend, P. C.; Stoy, S. T.; Kranyecz, T. E.

    1976-01-01

    The distribution of hydrogen chloride in the cloud was analyzed as a function of launch pad geometry and rate of rise of the vehicle during the first 24 sec of burn in order to define neutralization requirements. Delivery systems of various types were developed in order to bring the proposed chemical agents in close contact with the hydrogen chloride. Approximately one-third of the total neutralizing agent required can be delivered from a ground installed system at the launch pad; concentrated sodium carbonate solution is the preferred choice of agent for this launch pad system. Two-thirds of the neutralization requirement appears to need delivery by aircraft. Only one chemical agent (ammonia) may be reasonably considered for delivery by aircraft, because weight and bulk of all other agents are too large.

    1980-11-01

    The present official AOAC method (44.120(a)(b), 13th Ed.) for extracting light filth from ground allspice uses flammable solvents and gives poor filth recoveries. An improved method has been developed which uses a single pretreatment with 40% isopropanol and hydrochloric acid followed by wet sieving. After deaeration by boiling, the light filth is extracted from 40% isopropanol-Tween 80-tetrasodium EDTA with light mineral oil. Reports from all 6 collaborators showed that the proposed method resulted in 90 and 89% average recoveries of rodent hairs and insect fragments, respectively. The proposed method is recommended for adoption as official first action to replace AOAC (44.120(a)(b)) for allspice. PMID:7451389

    2011-01-01

    Context: Factors that affect food choices include the physical and social environments, quality, quantity, perceived healthfulness, and convenience. The personal food choice process was defined as the procedures used by athletes for making food choices, including the weighing and balancing of activities of daily life, physical well-being, convenience, monetary resources, and social relationships. Objective: To develop a theoretical model explaining the personal food choice processes of collegiate football players. Design: Qualitative study. Setting: National Collegiate Athletic Association Division II football program. Patients or Other Participants: Fifteen football players were purposefully sampled to represent various positions, years of athletic eligibility, and ethnic backgrounds. Data Collection and Analysis: For text data collection, we used predetermined, open-ended questions. Data were analyzed using the constant comparison method. The athletes' words were used to label and describe their interactions and experiences with the food choice process. Member checks and an external audit were conducted by a qualitative methodologist and a nutrition specialist, and the findings were triangulated with the current literature to ensure trustworthiness of the text data. Results: Time was the core category and yielded a cyclic graphic of a theoretical model for the food choice system. Planning hydration, macronutrient strategies, snacks, and healthful food choices emerged as themes. Conclusions: The athletes planned meals and snacks around their academic and athletic schedules while attempting to consume foods identified as healthful. Healthful foods were generally lower in fat but high in preferred macronutrients. High-protein foods were the players' primary goal; carbohydrate consumption was secondary. The athletes had established plans to maintain hydration. Professionals may use these findings to implement educational programs on food choices for football players

  1. Effects of territory competition and climate change on timing of arrival to breeding grounds: a game-theory approach.

    PubMed

    Johansson, Jacob; Jonzén, Niclas

    2012-04-01

    Phenology is an important part of life history that is gaining increased attention because of recent climate change. We use game theory to model phenological adaptation in migratory birds that compete for territories at their breeding grounds. We investigate how the evolutionarily stable strategy (ESS) for the timing of arrival is affected by changes in the onset of spring, the timing of the resource peak, and the season length. We compare the ESS mean arrival date with the environmental optimum, that is, the mean arrival date that maximizes fitness in the absence of competition. When competition is strong, the ESS mean arrival date responds less than the environmental optimum to shifts in the resource peak but more to changes in the onset of spring. Increased season length may not necessarily affect the environmental optimum but can still advance the ESS mean arrival date. Conversely, shifting a narrow resource distribution may change the environmental optimum without affecting the ESS mean arrival date. The ESS mean arrival date and the environmental optimum may even shift in different directions. Hence, treating phenology as an evolutionary game rather than an optimization problem fundamentally changes what we predict to be an adaptive response to environmental changes.

      A revised core curriculum model for pharmaceutical education, developed on the basis of the principles of outcome-based education, will be introduced in 2015. Inevitably, appropriate assessments of students' academic achievements will be required. Although evaluations of the cognitive domain can be carried out by paper tests, evaluation methods for the attitude domain and problem-solving abilities need to be established. From the viewpoint of quality assurance for graduates, pharmaceutical education reforms have become vital to evaluation as well as learning strategies. To evaluate student academic achievements on problem-solving abilities, authentic assessment is required. Authentic assessment is the evaluation that mimics the context tried in work and life. Specifically, direct evaluation of performances, demonstration or the learners' own work with integrated variety knowledge and skills, is required. To clarify the process of graduate research, we obtained qualitative data through focus group interviews with six teachers and analyzed the data using the modified grounded theory approach. Based on the results, we clarify the performance students should show in graduate research and create a rubric for evaluation of performance in graduate research. PMID:25743905

    1999-01-01

    A sensitivity study for the in-ground effect on aircraft wake vortices has been conducted using a validated large eddy simulation model. The numerical results are compared with observed data and show good agreement for vortex decay and lateral vortex transport. The vortex decay rate is strongly influenced by the ground, but appears somewhat insensitive to ambient turbulence. In addition, the results show that the ground can affect the trajectory and descent-rate of a wake vortex pair at elevations up to about 3 b(sub o) (where b(sub o) is the initial vortex separation). However, the ground does not influence the average circulation of the vortices until the cores descend to within about 0.6 b(sub o), after which time the ground greatly enhances their rate of demise. Vortex rebound occurs in the simulations, but is more subtle than shown in previous numerical studies.

    Introduction Although the group of vascular leg amputated patients constitutes some of the most vulnerable and frail on the orthopedic wards, previous research of amputated patients has focused on patients attending gait training in rehabilitation facilities leaving the patient experience shortly after surgery unexplored. Understanding patients’ behavior shortly after amputation could inform health professionals in regard to how these vulnerable patients’ needs at hospital can be met as well as how to plan for care post-discharge. Aim To construct a grounded theory (GT) explaining patients’ behavior shortly after having a leg amputated as a result of vascular disease. Method In line with constructivist GT methodology, data from ethnographic observations and interviews were simultaneously collected and analyzed using the constant comparative method covering the patients’ experiences during the first 4 weeks post-surgery. Data collection was guided by theoretical sampling and comprised 11 patients. A GT was constructed. Results Patients went through a three-phased process as they realized they were experiencing a life-changing event. The first phase was “Losing control” and comprised the sub-categories “Being overwhelmed” and “Facing dependency.” The second phase was “Digesting the shock” and comprised the sub-categories “Swallowing the life-changing decision,” “Detecting the amputated body” and “Struggling dualism.” The third phase was “Regaining control” and comprised the sub-categories “Managing consequences” and “Building-up hope and self-motivation.” “Pendulating” was identified as the core category describing the general pattern of behavior and illustrated how patients were swinging both cognitively and emotionally throughout the process. Conclusion The theory of “Pendulating” offers a tool to understand the amputated patients’ behavior and underlying concerns and to recognize where they are in the

  5. Detailed hydrochemical studies as a useful extension of national ground-water monitoring networks

    1995-09-01

    Regional and national ground-water monitoring networks are used to inventory and to monitor diffusive (nonpoint) sources of ground-water contamination. The Dutch National Ground Water Quality Monitoring Network (LMG) is an example of such a network and monitors the shallow ground water of The Netherlands at two depths (10 and 25 m below land surface) in 350 wells, giving an average density of one monitoring well per 100 km{sup 2}. Once water-quality changes have been observed in time and space, the regional network is less suited to the study of the detailed chemistry, dynamics, and scale of the observed changes, because of the low density of sampling points. Two important threats to the quality of ground water that were identified by the regional network were studied in greater detail by use of multilevel observation wells along cross sections parallel to the direction of ground-water flow. The first detailed study evaluates the fate of nitrate and other agricultural contaminants in a sandy aquifer recharged by precipitation. the second detailed study evaluates the effects of recharge from IJsssel river water in a sandy aquifer. The varying compositions of ground water are controlled by the hydrological flow patterns, the composition of the aquifer sediments and the composition of the source water. These controlling factors locally lead to relatively rapid transitions and heterogeneity of ground-water compositions. The transition zones are considerably smaller than the density of observation wells in the Dutch ground-water monitoring network, which limits the usefulness of regional monitoring networks for identifying chemically similar hydrologic zones or for effectively evaluating physical and chemical processes that affect the water quality. Regional patterns may evolve as a result of selective placement of monitoring wells, which show a specific fact of the ground-water quality of that region.

    2009-01-01

    The Interferometric Point Target Analysis (IPTA) technique and Advanced Synthetic Aperture Radar (ASAR) images acquired over Hong Kong from 2007–2008 were used to detect ground deformation in the urban area of Guangzhou city in South China. A ground deformation rate map with scattered distribution of point targets shows the maximum subsidence (rise) rate as high as -26 to -20 mma-1 (16–21 mma-1), implying that the study area is an active zone for ground deformation. Based on the point target map, a contour ground deformation rate map is generated. The map shows three major subsidence zones located in the middle-west, the east, and the southwest of the study area, respectively. All the six ground collapse accidents that occurred in 2007–2008 fall within the subsidence zones, qualitatively validating the IPTA results. Ground subsidence and geological conditions on Datansha Island are examined. The results indicate that the local geological conditions, such as limestone Karst geomorphology as well as silt layers characterized by high water content, high void ratio, high compressibility, low bearing capacity and low shear strength, and underground engineering projects are responsible for ground subsidence and ground collapse accidents occurred there.

  7. Prognostics for Ground Support Systems: Case Study on Pneumatic Valves

    NASA Technical Reports Server (NTRS)

    Daigle, Matthew; Goebel, Kai

    2011-01-01

    Prognostics technologies determine the health (or damage) state of a component or sub-system, and make end of life (EOL) and remaining useful life (RUL) predictions. Such information enables system operators to make informed maintenance decisions and streamline operational and mission-level activities. We develop a model-based prognostics methodology for pneumatic valves used in ground support equipment for cryogenic propellant loading operations. These valves are used to control the flow of propellant, so failures may have a significant impact on launch availability. Therefore, correctly predicting when valves will fail enables timely maintenance that avoids launch delays and aborts. The approach utilizes mathematical models describing the underlying physics of valve degradation, and, employing the particle filtering algorithm for joint state-parameter estimation, determines the health state of the valve and the rate of damage progression, from which EOL and RUL predictions are made. We develop a prototype user interface for valve prognostics, and demonstrate the prognostics approach using historical pneumatic valve data from the Space Shuttle refueling system.

  8. Study of the Probability Law Governing Ground Motion Metrics Recorded During the 2004 Parkfield Earthquake

    NASA Astrophysics Data System (ADS)

    Lavallee, D.

    2007-12-01

    Based on the superposition of seismic waves and the Central Limit Theorem, we developed the basis for a unified picture of earthquake variability from its recording in the ground motions to its inference in source models. According to this theory, the random properties of the ground motions and the source for a single earthquake should be both (approximately) distributed according to the Levy law. Computation of the probability density function (PDF) of the peak ground acceleration (PGA) of the 1999 Chi-Chi, the PDF of the PGA and the PDF of the peak ground velocity (PGV) of the 2004 Parkfield earthquakes confirms this theory. As predicted by the theory, we found that the tails of the PDF, characterizing the slip and the PGA, are attenuated according to power laws with exponents (denoted Levy indexes) that take almost the same values close to 1. Computations of the PDF of the PGA recorded at the surface and the PDF of the PGA recorded in borehole during the 2003 Tokachi-oki earthquake lead to a similar conclusion. The PDF tail measures the frequency at which large events occurred and thus quantifies the probability to observe large acceleration values and large velocity values during an earthquake. We extend our analysis of the random properties to other ground motion metrics. To lessen the dependency due to the source-to-site distance, we consider the ratio of the PGV to the PGA, the ratio of the two horizontal components of the PGA to the vertical component of the PGA, and the ratio of the horizontal components of the PGV to the vertical component of the PGV. In this analysis, we use the ground motions recorded during the 2004 Parkfield earthquake, arguably the best-recorded earthquake in history for the density of near-source data. We select stations located within a closest distance to the rupture surface that varies from 0 to 180 km. To test the effect of the distance on the computed random properties, these stations are divided into several subsets or windows

    Stewart, R. B.; Grose, W. L.

    1975-01-01

    Parametric studies were made with a multilayer atmospheric diffusion model to place quantitative limits on the uncertainty of predicting ground-level toxic rocket-fuel concentrations. Exhaust distributions in the ground cloud, cloud stabilized geometry, atmospheric coefficients, the effects of exhaust plume afterburning of carbon monoxide CO, assumed surface mixing-layer division in the model, and model sensitivity to different meteorological regimes were studied. Large-scale differences in ground-level predictions are quantitatively described. Cloud alongwind growth for several meteorological conditions is shown to be in error because of incorrect application of previous diffusion theory. In addition, rocket-plume calculations indicate that almost all of the rocket-motor carbon monoxide is afterburned to carbon dioxide CO2, thus reducing toxic hazards due to CO. The afterburning is also shown to have a significant effect on cloud stabilization height and on ground-level concentrations of exhaust products.

    Since 1952 water diverted from the Columbia River at Grand Coulee Dam has been used to irrigate parts of the Columbia Basin Irrigation Project area in eastern Washington, and as a result ground-water levels generally have risen in the area. The rapid increases in ground-water inflow, outflow, and storage from irrigation have created a need for a better understanding of the ground-water system before and after the start of irrigation to establish guidelines necessary for management of the area's ground-water resource. Data and information from previous geologic and hydrologic studies were used as a basis for quantitative analyses of ground-water inflow and outflow by means of digital computer models representing three major areas--Quincy Basin, Pasco Basin, and Royal Slope.

    2013-01-01

    NASA's LSP, GSDO and other programs use the probability of cloud-to-ground (CG) lightning occurrence issued by the 45th Weather Squadron (45 WS) in their daily and weekly lightning probability forecasts. These organizations use this information when planning potentially hazardous outdoor activities, such as working with fuels, or rolling a vehicle to a launch pad, or whenever personnel will work outside and would be at-risk from lightning. These organizations would benefit greatly if the 45 WS could provide more accurate timing of the first CG lightning strike of the day. The Applied Meteorology Unit (AMU) has made significant improvements in forecasting the probability of lightning for the day, but forecasting the time of the first CG lightning with confidence has remained a challenge. To address this issue, the 45 WS requested the AMU to determine if flow regimes, wind speed categories, or a combination of the two could be used to forecast the timing of the first strike of the day in the Kennedy Space Center (KSC)/Cape Canaveral Air Force Station (CCAFS) lightning warning circles. The data was stratified by various sea breeze flow regimes and speed categories in the surface to 5,000-ft layer. The surface to 5,000-ft layer was selected since that is the layer the 45 WS uses to predict the behavior of sea breeze fronts, which are the dominant influence on the occurrence of first lightning in Florida during the warm season. Due to small data sample sizes after stratification, the AMU could not determine a statistical relationship between flow regimes or speed categories and the time of the first CG strike.. As expected, although the amount and timing of lightning activity varies by time of day based on the flow regimes and speed categories, there are extended tails of low lightning activity making it difficult to specify times when the threat of the first lightning flash can be avoided. However, the AMU developed a graphical user interface with input from the 45 WS

    We derive the large-particle-number limit of the Bethe equations for the ground state of the attractive one-dimensional Bose gas (Lieb-Liniger model) on a ring and solve it for arbitrary coupling. We show that the ground state of this system can be mapped to the large-N saddle point of Euclidean Yang-Mills theory on a two-sphere with a U(N ) gauge group, and the phase transition that interpolates between the homogeneous and solitonic regime is dual to the Douglas-Kazakov confinement-deconfinement phase transition.

    The bimolecular reaction of ground state cyano radical with propylene under the condition of single collision is investigated by combining ab initio electronic structure calculations for predicting reaction paths and RRKM theory to yield rate constant for each path. The isomerization and dissociation channels for each of the seven collision complexes are characterized by utilizing the unrestricted B3LYP/cc-pVTZ level of theory and the CCSD(T)/cc-pVTZ calculations. Sifting with the facilitation of RRKM rate constants through web of ab initio paths composed of 8 collision complexes, 37 intermediates, and 12 H-, 23 H(2)-, 3 HCN-, and 4 CH(3)-dissociated products, we identify the most probable paths down to 7-9 species at collisions energies of 0 and 5 kcal/mol as the reaction mechanisms. The rate equations of the reaction mechanisms are solved numerically such that the concentration evolutions for all species involved are obtained. This study predicts that CN + C(2)H(3)CH(3) reaction via any of the seven collision complex, c1-c5, c7, and c8, would produce p1(CH(3)CHCHCN) + H, p2(CH(2)CHCH(2)CN) + H, and mostly p43(vinyl cyanide) + CH(3) for collision energy within 0-5 kcal/mol. In addition to the insertion mechanism through collision complex, the direct H-abstraction of propylene by CN radical might occur. Our investigation indicates that the barrierless and exoergic CN(X(2)Sigma(+)) + C(2)H(3)CH(3)(X(1)A') reaction would be an efficient route for the p1, p2, and p43, and likely HCN formation in cold molecular clouds and in the atmosphere of Saturn's satellite Titan.

    State-of-the-art ab initio techniques have been applied to compute the potential-energy curves for the ground X {sup 1}{sigma}{sub g}{sup +} and excited {sup 1}{pi}{sub g}(4s3d) states of the calcium dimer in the Born-Oppenheimer approximation. The weakly bound ground state was calculated by symmetry-adapted perturbation theory, while the strongly bound excited state was computed using a combination of the linear-response theory within the coupled-cluster singles and doubles framework for the core-valence electronic correlation and of the full configuration interaction for the valence-valence correlation. The ground-state potential has been corrected by considering the relativistic terms resulting from the first-order many-electron Breit theory, and the retardation corrections. The magnetic electronic transition dipole moment governing the {sup 1}{pi}{sub g}(leftarrow){sup 1}{sigma}{sub g}{sup +} transitions has been obtained as the first residue of the polarization propagator computed with the coupled-cluster method restricted to single and double excitations. The computed energies and transition moments have been analytically fitted and used in the dynamical calculations of the rovibrational energy levels, ground-state scattering length, photoassociation intensities at ultralow temperatures, and spontaneous emission coefficients from the {sup 1}{pi}{sub g}(4s3d) to the X {sup 1}{sigma}{sub g}{sup +} state. The spectroscopic constants of the theoretical ground-state potential are in a good agreement with the experimental values derived from the Fourier-transform spectra [O. Allard et al., Eur. Phys. J. D (to be published)]. The theoretical s-wave scattering length for the ground state is a=44 bohrs, suggesting that it should be possible to obtain a stable Bose-Einstein condensate of calcium atoms. Finally, the computed photoassociation intensities and spontaneous emission coefficients suggest that it should be possible to obtain cold calcium molecules by

    Excessive, rapid weight gain in early infancy has been linked to risk of later overweight and obesity. Inappropriate infant feeding practices associated with this rapid weight gain are currently of great interest. Understanding the origin of these practices may increase the effectiveness of interventions. Low-income populations in the Southeastern United States are at increased risk for development of inappropriate infant feeding practices, secondary to the relatively low rates of breastfeeding reported from this region. The objective was to use grounded theory methodology (GTM) to explore interactions between mothers and infants that may influence development of feeding practices, and to do so among low-income, primiparous, Southeastern United States mothers. Analysis of 15 in-depth phone interviews resulted in development of a theoretical model in which Mother-Infant Communication Dynamic emerged as the central concept. The central concept suggests a communication pattern developed over the first year of life, based on a positive feedback loop, which is harmonious and results in the maternal perception of mother and infant now speaking the same language. Importantly, though harmonious, this dynamic may result from inaccurate maternal interpretation of infant cues and behaviours, subsequently leading to inappropriate infant feeding practices. Future research should test this theoretical model using direct observation of mother-infant communication, to increase the understanding of maternal interpretation of infant cues. Subsequently, interventions targeting accurate maternal interpretation of and response to infant cues, and impact on rate of infant weight gain could be tested. If effective, health care providers could potentially use these concepts to attenuate excess rapid infant weight gain.

    Here we review 18 articles that describe the design and evaluation of 1 or more games for diabetes from technical, methodological, and theoretical perspectives. We undertook searches covering the period 2010 to May 2015 in the ACM, IEEE, Journal of Medical Internet Research, Studies in Health Technology and Informatics, and Google Scholar online databases using the keywords "children," "computer games," "diabetes," "games," "type 1," and "type 2" in various Boolean combinations. The review sets out to establish, for future research, an understanding of the current landscape of digital games designed for children with diabetes. We briefly explored the use and impact of well-established learning theories in such games. The most frequently mentioned theoretical frameworks were social cognitive theory and social constructivism. Due to the limitations of the reported evaluation methodologies, little evidence was found to support the strong promise of games for diabetes. Furthermore, we could not establish a relation between design features and the game outcomes. We argue that an in-depth discussion about the extent to which learning theories could and should be manifested in the design decisions is required.

    Objective. There is limited theory regarding the real-world implementation of mental health care in the primary care setting: a type of organizational coordination intervention. The purpose of this study was to develop a theory to conceptualize the potential causes of barriers and facilitators to how local sites responded to this mandated intervention to achieve coordinated mental health care. Methods. Data from 65 primary care and mental health staff interviews across 16 sites were analyzed to identify how coordination was perceived one year after an organizational mandate to provide integrated mental health care in the primary care setting. Results. Standardized referral procedures and communication practices between primary care and mental health were influenced by the organizational factors of resources, training, and work design, as well as provider-experienced organizational boundaries between primary care and mental health, time pressures, and staff participation. Organizational factors and provider experiences were in turn influenced by leadership. Conclusions. Our emergent theory describes how leadership, organizational factors, and provider experiences affect the implementation of a mandated mental health coordination intervention. This framework provides a nuanced understanding of the potential barriers and facilitators to implementing interventions designed to improve coordination between professional groups. PMID:22900158

    The aim of this study was to generate a substantive theory explaining how the staff in a resource-limited neonatal intensive care unit (NICU) of a developing nation manage to ensure adherence to behavioral modification components of a noise reduction protocol (NsRP) during nonemergency situations. The study was conducted after implementation of an NsRP in a level III NICU of south India. The normal routine of the NICU is highly dynamic because of various categories of staff conducting clinical rounds followed by care-giving activities. This is unpredictably interspersed with very noisy emergency management of neonates who suddenly fall sick. In-depth interviews were conducted with 36 staff members of the NICU (20 staff nurses, six nursing aides, and 10 physicians). Group discussions were conducted with 20 staff nurses and six nursing aides. Data analysis was done in line with the reformulated grounded theory approach, which was based on inductive examination of textual information. The results of the analysis showed that the main concern was to ensure adherence to behavioral modification components of the NsRP. This was addressed by using strategies to "sustain a culture of silence in NICU during nonemergency situations" (core category). The main strategies employed were building awareness momentum, causing awareness percolation, developing a sense of ownership, expansion of caring practices, evolution of adherence, and displaying performance indicators. The "culture of silence" reconditions the existing staff and conditions new staff members joining the NICU. During emergency situations, a "noisy culture" prevailed because of pragmatic neglect of behavioral modification when life support overrode all other concerns. In addition to this, the process of operant conditioning should be formally conducted once every 18 months. The results of this study may be adapted to create similar strategies and establish context specific NsRPs in NICUs with resource constraints.
