    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.

Not intended for a beginner, this book further defi nes, describes, and explicates the classic grounded theory (GT method. Perspective III lays out various facets of theoretical coding as Glaser meticulously distinguishes classic GT from other subsequent methods. Developed many years after Glaser’s classic GT, these methods, particularly as described by Strauss and Corbin, adopt the grounded theory name and engender ongoing confusion about the very premises of grounded theory. Glaser distinguishes between classic GT and the adscititious methods in his writings, referring to remodeled grounded theory and its offshoots as Qualitative Data Analysis (QDA models.

    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.

  6. Rigour and grounded theory.

    Science.gov (United States)

    Cooney, Adeline

    2011-01-01

    This paper explores ways to enhance and demonstrate rigour in a grounded theory study. Grounded theory is sometimes criticised for a lack of rigour. Beck (1993) identified credibility, auditability and fittingness as the main standards of rigour for qualitative research methods. These criteria were evaluated for applicability to a Straussian grounded theory study and expanded or refocused where necessary. The author uses a Straussian grounded theory study (Cooney, In press) to examine how the revised criteria can be applied when conducting a grounded theory study. Strauss and Corbin (1998b) criteria for judging the adequacy of a grounded theory were examined in the context of the wider literature examining rigour in qualitative research studies in general and grounded theory studies in particular. A literature search for 'rigour' and 'grounded theory' was carried out to support this analysis. Criteria are suggested for enhancing and demonstrating the rigour of a Straussian grounded theory study. These include: cross-checking emerging concepts against participants' meanings, asking experts if the theory 'fit' their experiences, and recording detailed memos outlining all analytical and sampling decisions. IMPLICATIONS FOR RESEARCH PRACTICE: The criteria identified have been expressed as questions to enable novice researchers to audit the extent to which they are demonstrating rigour when writing up their studies. However, it should not be forgotten that rigour is built into the grounded theory method through the inductive-deductive cycle of theory generation. Care in applying the grounded theory methodology correctly is the single most important factor in ensuring rigour.

    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.

    Engward, Hilary; Davis, Geraldine

    2015-07-01

    A discussion of the meaning of reflexivity in research with the presentation of examples of how a model of reflexivity was used in a grounded theory research project. Reflexivity requires the researcher to make transparent the decisions they make in the research process and is therefore important in developing quality in nursing research. The importance of being reflexive is highlighted in the literature in relation to nursing research, however, practical guidance as to how to go about doing research reflexively is not always clearly articulated. This is a discussion paper. The concept of reflexivity in research is explored using the Alvesson and Skoldberg model of reflexivity and practical examples of how a researcher developed reflexivity in a grounded theory project are presented. Nurse researchers are encouraged to explore and apply the concept of reflexivity in their research practices to develop transparency in the research process and to increase robustness in their research. The Alvesson and Skoldberg model is of value in applying reflexivity in qualitative nursing research, particularly in grounded theory research. Being reflexive requires the researcher to be completely open about decisions that are made in the research process. The Alvesson and Skolberg model of reflexivity is a useful model that can enhance reflexivity in the research process. It can be a useful practical tool to develop reflexivity in grounded theory research. © 2015 John Wiley & Sons Ltd.

    2015-11-01

    Self-immolation is a common method of suicide among Iranian women. There are several contributing motives for attempting self-immolation, and exploration of the process of self-immolation incidents will help interventionists and clinicians develop prevention programs. A grounded theory study using face-to-face, recorded interviews was conducted with surviving self-immolated patients (n=14), their close relatives (n=5), and medical staff (n=8) in Kermanshah, Iran. Data were analyzed using constant comparison in open, axial, and selective coding stages. A conceptual model was developed to explain the relationships among the main categories extracted through the grounded theory study. Family conflicts emerged as the core category. Cultural context of self-immolated patients offered a contextual condition. Other important categories linked to the core category were mental health problems, distinct characteristics of the suicidal method, and self-immolation as a threat. The role of mental health problems as a causal condition was detected in different levels of the self-immolation process. Finally, adverse consequences of self-immolation emerged as having important impact. The conceptual model, derived through grounded theory study, can guide design of prevention programs. The pivotal role of family conflicts should be emphasized in mental health interventions. The impact of adverse consequences of self-immolation on further suicidal processes necessitates post-suicide prevention programs. Further research to design specific interventions is recommended.

    2017-12-01

    Role modelling by experienced nurses, including nurse academics, is a key factor in the process of preparing undergraduate nursing students for practice, and may contribute to longevity in the workforce. A grounded theory study was undertaken to investigate the phenomenon of nurse academics' role modelling for undergraduate students. The study sought to answer the research question: how do nurse academics role model positive professional behaviours for undergraduate students? The aims of this study were to: theorise a process of nurse academic role modelling for undergraduate students; describe the elements that support positive role modelling by nurse academics; and explain the factors that influence the implementation of academic role modelling. The study sample included five second year nursing students and sixteen nurse academics from Australia and the United Kingdom. Data was collected from observation, focus groups and individual interviews. This study found that in order for nurse academics to role model professional behaviours for nursing students, they must reconcile their own professional identity. This paper introduces the theory of reconciling professional identity and discusses the three categories that comprise the theory, creating a context for learning, creating a context for authentic rehearsal and mirroring identity.

  18. How robotics programs influence young women's career choices : a grounded theory model

    Science.gov (United States)

    Craig, Cecilia Dosh-Bluhm

    The fields of engineering, computer science, and physics have a paucity of women despite decades of intervention by universities and organizations. Women's graduation rates in these fields continue to stagnate, posing a critical problem for society. This qualitative grounded theory (GT) study sought to understand how robotics programs influenced young women's career decisions and the program's effect on engineering, physics, and computer science career interests. To test this, a study was mounted to explore how the FIRST (For Inspiration and Recognition of Science and Technology) Robotics Competition (FRC) program influenced young women's college major and career choices. Career theories suggested that experiential programs coupled with supportive relationships strongly influence career decisions, especially for science, technology, engineering, and mathematics careers. The study explored how and when young women made career decisions and how the experiential program and! its mentors and role models influenced career choice. Online focus groups and interviews (online and face-to-face) with 10 female FRC alumnae and GT processes (inductive analysis, open coding, categorizations using mind maps and content clouds) were used to generate a general systems theory style model of the career decision process for these young women. The study identified gender stereotypes and other career obstacles for women. The study's conclusions include recommendations to foster connections to real-world challenges, to develop training programs for mentors, and to nurture social cohesion, a mostly untapped area. Implementing these recommendations could help grow a critical mass of women in engineering, physics, and computer science careers, a social change worth pursuing.

    2010-04-01

    A limited number of studies have explored parental depression in the postadoption time periods and these studies frequently lack a social context of the adoptive parent experience. The objective of this study is to form a midrange theoretical interpretation of parental postadoption depression as shared by adoptive parents and experts through a grounded theory approach. Semistructured interviews of adoptive parents, who acknowledge being depressed after the child is placed in the home, and adoption experts are audiotaped, transcribed, and coded to reveal themes. In total, 30 interviews are conducted. Researchers are also participant-observers during an adoptive parent support group meeting. Data reveal recurrent themes in relation to postadoption depression. These themes take into account the various contexts of adoption (international and domestic, public and private, etc.). Parents express unfulfilled and unrealistic expectations in the domains of self, child, family or friends, and society or others. A theoretical model is presented to facilitate the understanding of depression reported by adoptive parents.

    2016-08-01

    The Mental Health Commission of Canada was formed as a national catalyst for improving the mental health system. One of its initiatives is Opening Minds (OM), whose mandate is to reduce mental health-related stigma. This article reports findings from a qualitative study on antistigma interventions for healthcare providers, which includes a process model articulating key stages and strategies for implementing successful antistigma programmes. The study employed a grounded theory methodology. Data collection involved in-depth interviews with programme stakeholders, direct observation of programmes, a review of programme documents, and qualitative feedback from programme participants. Analysis proceeded via the constant comparison method. A model was generated to visually present key findings. Twenty-three in-depth interviews were conducted representing 18 different programmes. Eight programmes were observed directly, 48 programme documents were reviewed, and data from 1812 programme participants were reviewed. The analysis led to a four-stage process model for implementing successful antistigma programmes targeting healthcare providers, informed by the basic social process 'targeting the roots of healthcare provider stigma'. The process model developed through this research may function as a tool to help guide the development and implementation of antistigma programmes in healthcare contexts. © 2016 John Wiley & Sons A/S.

    2013-06-01

    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. © 2013 Wiley Publishing Asia Pty Ltd.

    2016-02-01

    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.

  5. Variational theory of valence fluctuations: Ground states and quasiparticle excitations of the Anderson lattice model

    Science.gov (United States)

    Brandow, B. H.

    1986-01-01

    A variational study of ground states of the orbitally nondegenerate Anderson lattice model, using a wave function with one variational parameter per Bloch state k, has been extended to deal with essentially metallic systems having a nonintegral number of electrons per site. Quasiparticle excitations are obtained by direct appeal to Landau's original definition for interacting Fermi liquids, scrEqp(k,σ)=δEtotal/δn qp(k,σ). This approach provides a simple and explicit realization of the Luttinger picture of a periodic Fermi liquid. A close correspondence is maintained between the ``interacting'' (U=∞) system and the corresponding ``noninteracting'' (U=0) case, i.e., ordinary band theory; the result can be described as a renormalized band or renormalized hybridization theory. The occupation-number distribution for the conduction orbitals displays a finite discontinuity at the Fermi surface. If the d-f hybridization is nonzero throughout the Brillouin zone, the quasiparticle spectrum will always exhibit a gap, although this gap becomes exponentially small (i.e., of order TK) in the Kondo-lattice regime. In the ``ionic'' case with precisely two electrons per site, such a system may therefore exhibit an insulating (semiconducting) gap. The quasiparticle state density exhibits a prominent spike on each side of the spectral gap, just as in the elementary hybridization model (the U=0 case). For the metallic case, with a nonintegral number of electrons per site, the Fermi level falls within one of the two sharp density peaks. The effective mass at the Fermi surface tends to be very large; enhancements by a factor >~102 are quite feasible. The foregoing variational theory has also been refined by means of a trial wave function having two variational parameters per Bloch state k. The above qualitative features are all retained, with some quantitative differences, but there are also some qualitatively new features. The most interesting of these is the appearance, within

    2012-01-01

    Grounded theory is one of the most common methodologies used in constructivist (qualitative) music therapy research. Researchers use the term "grounded theory" when denoting varying research designs and theoretical outcomes. This may be challenging for novice researchers when considering whether grounded theory is appropriate for their research phenomena. This paper examines grounded theory within music therapy research. Grounded theory is briefly described, including some of its "contested" ideas. A literature search was conducted using the descriptor "music therapy and grounded theory" in Pubmed, CINAHL PsychlNFO, SCOPUS, ERIC (CSA), Web of Science databases, and a music therapy monograph series. A descriptive analysis was performed on the uncovered studies to examine researched phenomena, grounded theory methods used, and how findings were presented, Thirty music therapy research projects were found in refereed journals and monographs from 1993 to "in press." The Strauss and Corbin approach to grounded theory dominates the field. Descriptors to signify grounded theory components in the studies greatly varied. Researchers have used partial or complete grounded theory methods to examine clients', family members', staff, music therapy "overhearers," music therapists', and students' experiences, as well as music therapy creative products and professional views, issues, and literature. Seven grounded theories were offered. It is suggested that grounded theory researchers clarify what and who inspired their design, why partial grounded theory methods were used (when relevant), and their ontology. By elucidating assumptions underpinning the data collection, analysis, and findings' contribution, researchers will continue to improve music therapy research using grounded theory methods.

    2013-04-01

    Effectiveness of educational interventions targeted at improving delirium care is limited by implementation barriers. Studying factors which shape learning needs can overcome these knowledge transfer barriers. This in-depth qualitative study explores learning needs of hospital staff relating to care needs of the confused older patients. Fifteen research participants from across the healthcare spectrum working within an acute care setting were interviewed. Five focus groups were undertaken with patients, carers, and mental health specialists. A Grounded Theory methodology was adopted and data were analyzed thematically in parallel to collection until theoretical saturation was reached. Eight categories of practice gap emerged: ownership of the confused patient, negative attitudes, lack of understanding of how frightened the patient is in hospital, carer partnerships, person-centered care, communication, recognition of cognitive impairment and specific clinical needs (e.g. capacity assessments). Conceptually, the learning needs were found to be hierarchically related. Moreover, a vicious circle relating to the core learning needs of ownership, attitudes and patient's fear emerged. A patient with delirium may be frightened in an alien environment and then negatively labeled by staff who subsequently wish for their removal, thereby worsening the patient's fear. These findings reconceptualize delirium education approaches suggesting a need to focus interventions on core level practice gaps. This fresh perspective on education, away from disease-based delirium knowledge toward work-based patient, team and practice knowledge, could lead to more effective educational strategies to improve delirium care.

    Full Text Available The message in this book, the dictum in this book, is to stop and write when the Grounded Theory (GT methodology puts you in that ready position. Stop unending conceptualization, unending data coverage, and unending listening to others who would egg you on with additional data, ideas and/or requirements or simply wait too long. I will discuss these ideas in detail. My experience with PhD candidates is that for the few who write when ready, many do not and SHOULD. Simply put, many write-up, but many more should.

    Existing theories of self-directed learning (SDL) have emphasized the importance of process, personal, and contextual factors. Previous medical education research has largely focused on the process of SDL. We explored the experience with and perception of SDL among internal medicine residents to gain understanding of the personal and contextual factors of SDL in graduate medical education. Using a constructivist grounded theory approach, we conducted 7 focus group interviews with 46 internal medicine residents at an academic medical center. We processed the data by using open coding and writing analytic memos. Team members organized open codes to create axial codes, which were applied to all transcripts. Guided by a previous model of SDL, we developed a theoretical model that was revised through constant comparison with new data as they were collected, and we refined the theory until it had adequate explanatory power and was appropriately grounded in the experiences of residents. We developed a theoretical model of SDL to explain the process, personal, and contextual factors affecting SDL during residency training. The process of SDL began with a trigger that uncovered a knowledge gap. Residents progressed to formulating learning objectives, using resources, applying knowledge, and evaluating learning. Personal factors included motivations, individual characteristics, and the change in approach to SDL over time. Contextual factors included the need for external guidance, the influence of residency program structure and culture, and the presence of contextual barriers. We developed a theoretical model of SDL in medical education that can be used to promote and assess resident SDL through understanding the process, person, and context of SDL.

  14. Correlations of zero-entropy critical states in the XXZ model: integrability and Luttinger theory far from the ground state

    Directory of Open Access Journals (Sweden)

    R. Vlijm, I. S. Eliëns, J. -S. Caux

    2016-10-01

    Full Text Available Pumping a finite energy density into a quantum system typically leads to `melted' states characterized by exponentially-decaying correlations, as is the case for finite-temperature equilibrium situations. An important exception to this rule are states which, while being at high energy, maintain a low entropy. Such states can interestingly still display features of quantum criticality, especially in one dimension. Here, we consider high-energy states in anisotropic Heisenberg quantum spin chains obtained by splitting the ground state's magnon Fermi sea into separate pieces. Using methods based on integrability, we provide a detailed study of static and dynamical spin-spin correlations. These carry distinctive signatures of the Fermi sea splittings, which would be observable in eventual experimental realizations. Going further, we employ a multi-component Tomonaga-Luttinger model in order to predict the asymptotics of static correlations. For this effective field theory, we fix all universal exponents from energetics, and all non-universal correlation prefactors using finite-size scaling of matrix elements. The correlations obtained directly from integrability and those emerging from the Luttinger field theory description are shown to be in extremely good correspondence, as expected, for the large distance asymptotics, but surprisingly also for the short distance behavior. Finally, we discuss the description of dynamical correlations from a mobile impurity model, and clarify the relation of the effective field theory parameters to the Bethe Ansatz solution.

    The decision to use grounded theory is not an easy one and this article aims to illustrate and explore the methodological complexity and decision-making process. It explores the decision making of one researcher in the first two years of a grounded theory PhD study looking at the psychosocial training needs of nurses and healthcare assistants working with people with dementia in residential care. It aims to map out three different approaches to grounded theory: classic, Straussian and constructivist. In nursing research, grounded theory is often referred to but it is not always well understood. This confusion is due in part to the history of grounded theory methodology, which is one of development and divergent approaches. Common elements across grounded theory approaches are briefly outlined, along with the key differences of the divergent approaches. Methodological literature pertaining to the three chosen grounded theory approaches is considered and presented to illustrate the options and support the choice made. The process of deciding on classical grounded theory as the version best suited to this research is presented. The methodological and personal factors that directed the decision are outlined. The relative strengths of Straussian and constructivist grounded theories are reviewed. All three grounded theory approaches considered offer the researcher a structured, rigorous methodology, but researchers need to understand their choices and make those choices based on a range of methodological and personal factors. In the second article, the final methodological decision will be outlined and its research application described.

    2006-12-01

    The grounded theory method provides a systematic way to generate theoretical constructs or concepts that illuminate psychosocial processes common to individual who have a similar experience of the phenomenon under investigation. There has been an increase in the number of published research reports that use the grounded theory method. However, there has been less medical education research, which is based on the grounded theory tradition. The purpose of this paper is to introduce basic tenants of qualitative research paradigm with specific reference to ground theory. The paper aims to encourage readers to think how they might possibly use the grounded theory method in medical education research and to apply such a method to their own areas of interest. The important features of a grounded theory as well as its implications for medical education research are explored. Data collection and analysis are also discussed. It seems to be reasonable to incorporate knowledge of this kind in medical education research.

    2011-01-01

    In this paper, the choice of classic grounded theory will be discussed and justified in the context of the first author's PhD research. The methodological discussion takes place within the context of PhD research entitled: Development of a stakeholder-led framework for a structured education programme that will prepare nurses and healthcare assistants to deliver a psychosocial intervention for people with dementia. There is a lack of research and limited understanding of the effect of psychosocial interventions on people with dementia. The first author thought classic grounded theory a suitable research methodology to investigate as it is held to be ideal for areas of research where there is little understanding of the social processes at work. The literature relating to the practical application of classic grounded theory is illustrated using examples relating to four key grounded theory components: Theory development: using constant comparison and memoing, Methodological rigour, Emergence of a core category, Inclusion of self and engagement with participants. Following discussion of the choice and application of classic grounded theory, this paper explores the need for researchers to visit and understand the various grounded theory options. This paper argues that researchers new to grounded theory must be familiar with and understand the various options. The researchers will then be able to apply the methodologies they choose consistently and critically. Doing so will allow them to develop theory rigorously and they will ultimately be able to better defend their final methodological destinations.

  6. Essential methodological considerations when using grounded theory.

    Science.gov (United States)

    Achora, Susan; Matua, Gerald Amandu

    2016-07-01

    To suggest important methodological considerations when using grounded theory. A research method widely used in nursing research is grounded theory, at the centre of which is theory construction. However, researchers still struggle with some of its methodological issues. Although grounded theory is widely used to study and explain issues in nursing practice, many researchers are still failing to adhere to its rigorous standards. Researchers should articulate the focus of their investigations - the substantive area of interest as well as the focal population. This should be followed by a succinct explanation of the strategies used to collect and analyse data, supported by clear coding processes. Finally, the resolution of the core issues, including the core category and related categories, should be explained to advance readers' understanding. Researchers should endeavour to understand the tenets of grounded theory. This enables 'neophytes' in particular to make methodological decisions that will improve their studies' rigour and fit with grounded theory. This paper complements the current dialogue on improving the understanding of grounded theory methodology in nursing research. The paper also suggests important procedural decisions researchers need to make to preserve their studies' scientific merit and fit with grounded theory.

  9. Grounded theory research: literature reviewing and reflexivity.

    Science.gov (United States)

    McGhee, Gerry; Marland, Glenn R; Atkinson, Jacqueline

    2007-11-01

    This paper is a report of a discussion of the arguments surrounding the role of the initial literature review in grounded theory. Researchers new to grounded theory may find themselves confused about the literature review, something we ourselves experienced, pointing to the need for clarity about use of the literature in grounded theory to help guide others about to embark on similar research journeys. The arguments for and against the use of a substantial topic-related initial literature review in a grounded theory study are discussed, giving examples from our own studies. The use of theoretically sampled literature and the necessity for reflexivity are also discussed. Reflexivity is viewed as the explicit quest to limit researcher effects on the data by awareness of self, something seen as integral both to the process of data collection and the constant comparison method essential to grounded theory. A researcher who is close to the field may already be theoretically sensitized and familiar with the literature on the study topic. Use of literature or any other preknowledge should not prevent a grounded theory arising from the inductive-deductive interplay which is at the heart of this method. Reflexivity is needed to prevent prior knowledge distorting the researcher's perceptions of the data.

  10. Demystifying Theoretical Sampling in Grounded Theory Research

    Directory of Open Access Journals (Sweden)

    Jenna Breckenridge BSc(Hons,Ph.D.Candidate

    2009-06-01

    Full Text Available Theoretical sampling is a central tenet of classic grounded theory and is essential to the development and refinement of a theory that is ‘grounded’ in data. While many authors appear to share concurrent definitions of theoretical sampling, the ways in which the process is actually executed remain largely elusive and inconsistent. As such, employing and describing the theoretical sampling process can present a particular challenge to novice researchers embarking upon their first grounded theory study. This article has been written in response to the challenges faced by the first author whilst writing a grounded theory proposal. It is intended to clarify theoretical sampling for new grounded theory researchers, offering some insight into the practicalities of selecting and employing a theoretical sampling strategy. It demonstrates that the credibility of a theory cannot be dissociated from the process by which it has been generated and seeks to encourage and challenge researchers to approach theoretical sampling in a way that is apposite to the core principles of the classic grounded theory methodology.

    Full Text Available Different genres of underground music are important issues in Iranian youth culture. The purpose of this research was to study masculinity in Iranian- Persian rap music. Therefore, Persian rap music as a part of Iranian popular culture, between 2001 and 2011 was analyzed. We used qualitative research approach. The main method used in this study, was "Constructive Grounded Theory ". So instead of using existing theories as a theoretical framework, the researcher sought to generate local theory from research field. Thus, using theoretical sampling, data compiled from various sources. The multiple data collection techniques such as interviews, observation, online observation, collecting documents and texts were used. Then all the data was coded with using open, axial and selective coding methods. Finally, 62 concepts and 16 categories derived from data and "plural form of masculinity in Iranian-Persian rap music" was defined as the core category. Then according to paradigmatic model, "Substantive Theory" emerged from the data, was presented as "story" and "visual model". Finally seven questions of Strauss and Corbin about the experience in research has been assessed to evaluating research.

    Hoarea, Karen J; Millsc, Jane; Francis, Karen

    2013-01-01

    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.

  1. Grounded theory: building a middle-range theory in nursing

    Directory of Open Access Journals (Sweden)

    Maria João Fernandes

    2015-03-01

    Full Text Available The development of nursing as a discipline results from a boom of investigations underway for nearly a century, and of the construction of theories that have arisen during the 1950’s, with greater relevance since the 1960’s. Giving continuation to the production of knowledge in nursing and seeking to contribute to the increase in the number of explanatory theories of the functional content of nurses, there is interest in answering the question: how can a middle-range theory in nursing be built that explains the nurse-elderly interaction in a successful aging process? As well, we address the goal of describing the process of building a middle-range theory in nursing. Middle-range theory refers to a qualitative paradigm study of inductive thinking, developed in the context of primary health care. The information was collected through participant observation and interviews. Method of analysis grounded theory by Corbin and Strauss(1 was followed, utilizing the triangulation of data and theoretical sampling. Grounded theory has become a method of analysis which facilitates the understanding and explanation of the phenomenon under study. By making clear the nature and process of the nurse-elderly interaction in the selected context and within the context of successful aging, a middle-range theory proposal emerged.

    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.

  3. How to Develop a Multi-Grounded Theory: the evolution of a business process theory

    Directory of Open Access Journals (Sweden)

    Mikael Lind

    2006-05-01

    Full Text Available In the information systems field there is a great need for different theories. Theory development can be performed in different ways – deductively and/or inductively. Different approaches with their pros and cons for theory development exists. A combined approach, which builds on inductive as well as deductive thinking, has been put forward – a Multi-Grounded Theory approach. In this paper the evolution of a business process theory is regarded as the development of a multi-grounded theory. This evolution is based on empirical studies, theory-informed conceptual development and the creation of conceptual cohesion. The theoretical development has involved a dialectic approach aiming at a theoretical synthesis based on antagonistic theories. The result of this research process was a multi-grounded business process theory. Multi-grounded means that the theory is empirically, internally and theoretically founded. This business process theory can be used as an aid for business modellers to direct attention towards relevant aspects when business process determination is performed.

    Despite the growing importance of spiritual care, the delivery of spiritual care is still an area of disagreement among healthcare providers. To develop a grounded theory about spiritual care delivery based on Iranian nurses' perceptions and experiences. A grounded theory approach: A qualitative study using the grounded theory approach. Participants and research context: Data were collected through holding 27 interviews with 25 participants (17 staff nurses, 3 physicians, 3 patients, 1 family member, and 1 nurse assistant). The study setting was the Imam Khomeini Hospital Complex. Sampling was started purposively and continued theoretically. Data analysis was performed by the method proposed by Strauss and Corbin. Ethical consideration: The study was approved by the Ethics Committee of Tarbiat Modares University and the agreement of the administrators of the study setting was got before starting the study. The core category of the study was "Trust building" which reflected the nature of spiritual care delivery by nurses. Trust building was the result of eight main categories or strategies including creating a positive mentality at hospital admission, understanding patients in care circumstances, having a caring presence, adhering to care ethics, developing meaningful relationships, promoting positive thinking and energy, establishing effective communication with patients, and attempting to create a safe therapeutic environment. Poor interprofessional coordination negatively affected this process while living toward developing greater cognizance of divinity and adhering to the principles of professional ethics facilitated it. The outcome of the process was to gain a sense of partial psychological security. The "Trust building" theory can be used as a guide for describing and expanding nurses' roles in spiritual care delivery, developing care documentation systems and clinical guidelines, and planning educational programs for nursing students and staff nurses.

    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.

In fact, the overlap increases as the lattice regulator is removed. This opens up the possibility that the Coulomb state is the true ground state in the continuum limit.

  8. Challenging convention: symbolic interactionism and grounded theory.

    Not very much is written in the literature about decisions made by researchers and the justifications on method as a result of a particular clinical problem, together with an appropriate and congruent theoretical perspective, particularly for Glaserian grounded theory. I contend the utilisation of symbolic interactionism as a theoretical perspective to inform and guide the evolving research process and analysis of data when using classic or Glaserian grounded theory (GT) method, is not always appropriate. Within this article I offer an analysis of the key issues to be addressed when contemplating the use of Glaserian GT and the utilisation of an appropriate theoretical perspective, rather than accepting convention of symbolic interactionism (SI). The analysis became imperative in a study I conducted that sought to explore the concerns, adaptive behaviours, psychosocial processes and relevant interactions over a 12-month period, among newly diagnosed persons with end stage renal disease, dependent on haemodialysis in the home environment for survival. The reality of perception was central to the end product in the study. Human ethics approval was granted by six committees within New South Wales Health Department and one from a university.

  9. Novel interpolative perturbation theory for quantum anharmonic oscillators in one and three dimensions and the ground state of a lattice model of the phi4 field theory

    A new method for approximating the eigenfunctions and eigenvalues of anharmonic oscillators. An attempt was made to develop an analytic method which provides simple formulae for all values of the parameters as the W.K.B. approximation and perturbation theory do for certain limiting case, and which has the convergence properties associated with the computer methods. The procedure is based upon combining knowledge of the asymptotic behavior of the wave function for large and small values of the coordinate(s) to obtain approximations valid for all values of coordinate(s) and all strengths of the anharmonicity. A systematic procedure for improving these approximations is developed. Finally the groundstate of a lattice model of the phi 4 field theory which consists of an infinite number of coupled anharmonic oscillators. A first order calculation yields a covariant expression for the groundstate eigenvalue with the physical mass, m, given by a characteristic polynomial which involves the bare mass, μ, the lattice spacing, l, and the coupling constant, lambda. For l > 0, μ can be adjusted (a mass renormalization) 0 < m < infinity. As l → 0 lambda (l) (a charge renormalization) is adjusted so that lambda/sup 1/3//l → eta, a constant, as l → 0. Then eta can be chosen so that m can take any experimental value

    A Grounded Theory on Helping Behavior and Its Shaping Factors

    2006-06-01

    Full Text Available In social psychology, the attribution model of helping behavior suggests that beliefs of the helping target’s responsibility for the need for help evoke affective motivators such as feelings of pity, sympathy, or anger. The affective motivation leads to helping or not helping the target. The current emergent theory is an enhancement of this theory by incorporating other personal and situational variables.Through the use of classic grounded theory, I interviewed 80 participants from different De La Salle Schools in the Philippines. This yielded over 1300 individual incidents that were compared and contrasted to form codes, categories and subcategories. A theory on the decision making process of helping emerged that incorporates the helper’s personal conviction, and rational deliberations of the situation. The desire to help is based on the helper’s rationalemotive beliefs (philosophical ideals and values that nurture helping and the knowledge of the nature of risk/problem and relational-emotive ties (with the one who needs help and with a social group that nurtures helping. The desire to help undergoes a process of rationalpragmatic-deliberations on the appropriateness of the recipients need of help, the cost of helping, the helper’s capability of helping, and the logistics of helping before the actual helping occurs. The theory has implications for current social psychological theories of helping, and the use of classic grounded theory research.

  11. The Methodological Dynamism of Grounded Theory

    2015-11-01

    Full Text Available Variations in grounded theory (GT interpretation are the subject of ongoing debate. Divergences of opinion, genres, approaches, methodologies, and methods exist, resulting in disagreement on what GT methodology is and how it comes to be. From the postpositivism of Glaser and Strauss, to the symbolic interactionist roots of Strauss and Corbin, through to the constructivism of Charmaz, the field of GT methodology is distinctive in the sense that those using it offer new ontological, epistemological, and methodological perspectives at specific moments in time. We explore the unusual dynamism attached to GT’s underpinnings. Our view is that through a process of symbolic interactionism, in which generations of researchers interact with their context, moments are formed and philosophical perspectives are interpreted in a manner congruent with GT’s essential methods. We call this methodological dynamism, a process characterized by contextual awareness and moment formation, contemporaneous translation, generational methodology, and methodological consumerism.

In particular, the authors find that the 'ground cone' preserved by the ring structure is promoted to a three-dimensional hyperboloid as conjectured by Witten. On the other hand, the perturbed (1,1) current algebra of moduli deformations is computed completely, and no simple geometrical interpretation is found.

    Barry, Michele J; Hauck, Yvonne L; O'Donoghue, Thomas; Clarke, Simon

    2013-12-01

    Midwifery has developed its own philosophy to formalise its unique identity as a profession. Newly-graduated midwives are taught, and ideally embrace, this philosophy during their education. However, embarking in their career within a predominantly institutionalised and the medically focused health-care model may challenge this application. The research question guiding this study was as follows: 'How do newly graduated midwives deal with applying the philosophy of midwifery in their first six months of practice?' The aim was to generate a grounded theory around this social process. This Western Australian grounded theory study is conceptualised within the social theory of symbolic interactionism. Data were collected by means of in-depth, semi-structured interviews with 11 recent midwifery graduates. Participant and interviewer's journals provided supplementary data. The 'constant comparison' approach was used for data analysis. The substantive theory of transcending barriers was generated. Three stages in transcending barriers were identified: Addressing personal attributes, Understanding the 'bigger picture', and finally, 'Evaluating, planning and acting' to provide woman-centred care. An overview of these three stages provides the focus of this article. The theory of transcending barriers provides a new perspective on how newly-graduated midwives deal with applying the philosophy of midwifery in their first six months of practice. A number of implications for pre and post registration midwifery education and policy development are suggested, as well as recommendations for future research. Copyright © 2013 Elsevier Ltd.

    Full Text Available ABSTRACT Objective: to understand the meaning of the university management performed by nurses managers of the nursing undergraduate course of a public university. Method: this is a qualitative research, based on the grounded theory. Data collection took place between May and September 2016, with open interviews, in the scenario of a federal public university. The technique of constant comparative analysis of the data was followed, obtaining a theoretical sample with 19 nurses, in two sample groups. Results: there were three categories emerged that shaped the phenomenon: Articulating complex collectives through university management for the qualified training of new nurses. The categories included: a conditions, defined by perceiving the commitment to the collective, previous experiences, and training for health management, as motivations to be a teacher manager; b actions/interactions, delimited by Knowing and recognizing, in practice, the university management process, limits and possibilities in the coordination of complex collective subjects; and, c consequences, such as Improving teaching work and taking responsibility for university education. Conclusion: the nurses teaching managers to explain university management as a set of individual and collective actions that, articulated in a complex social environment, promote conditions for the training of critical and reflexive nurses with the demands of society.

    Kennedy, Tara J T; Lingard, Lorelei A

    2006-02-01

    Grounded theory is a research methodology designed to develop, through collection and analysis of data that is primarily (but not exclusively) qualitative, a well-integrated set of concepts that provide a theoretical explanation of a social phenomenon. This paper aims to provide an introduction to key features of grounded theory methodology within the context of medical education research. In this paper we include a discussion of the origins of grounded theory, a description of key methodological processes, a comment on pitfalls encountered commonly in the application of grounded theory research, and a summary of the strengths of grounded theory methodology with illustrations from the medical education domain. The significant strengths of grounded theory that have resulted in its enduring prominence in qualitative research include its clearly articulated analytical process and its emphasis on the generation of pragmatic theory that is grounded in the data of experience. When applied properly and thoughtfully, grounded theory can address research questions of significant relevance to the domain of medical education.

    Qualitative methodologies are increasingly popular in medical research. Grounded theory is the methodology most-often cited by authors of qualitative studies in medicine, but it has been suggested that many 'grounded theory' studies are not concordant with the methodology. In this paper we provide a worked example of a grounded theory project. Our aim is to provide a model for practice, to connect medical researchers with a useful methodology, and to increase the quality of 'grounded theory' research published in the medical literature. We documented a worked example of using grounded theory methodology in practice. We describe our sampling, data collection, data analysis and interpretation. We explain how these steps were consistent with grounded theory methodology, and show how they related to one another. Grounded theory methodology assisted us to develop a detailed model of the process of adapting preventive protocols into dental practice, and to analyse variation in this process in different dental practices. By employing grounded theory methodology rigorously, medical researchers can better design and justify their methods, and produce high-quality findings that will be more useful to patients, professionals and the research community.

  6. Modeled ground water age distributions

    Science.gov (United States)

    Woolfenden, Linda R.; Ginn, Timothy R.

    2009-01-01

    The age of ground water in any given sample is a distributed quantity representing distributed provenance (in space and time) of the water. Conventional analysis of tracers such as unstable isotopes or anthropogenic chemical species gives discrete or binary measures of the presence of water of a given age. Modeled ground water age distributions provide a continuous measure of contributions from different recharge sources to aquifers. A numerical solution of the ground water age equation of Ginn (1999) was tested both on a hypothetical simplified one-dimensional flow system and under real world conditions. Results from these simulations yield the first continuous distributions of ground water age using this model. Complete age distributions as a function of one and two space dimensions were obtained from both numerical experiments. Simulations in the test problem produced mean ages that were consistent with the expected value at the end of the model domain for all dispersivity values tested, although the mean ages for the two highest dispersivity values deviated slightly from the expected value. Mean ages in the dispersionless case also were consistent with the expected mean ages throughout the physical model domain. Simulations under real world conditions for three dispersivity values resulted in decreasing mean age with increasing dispersivity. This likely is a consequence of an edge effect. However, simulations for all three dispersivity values tested were mass balanced and stable demonstrating that the solution of the ground water age equation can provide estimates of water mass density distributions over age under real world conditions.

    The purpose of this study was to explore the assertiveness process in Iranian nursing leaders. A qualitative design based on the grounded theory approach was used to collect and analyze the assertiveness experiences of 12 nurse managers working in four hospitals in Iran. Purposeful and theoretical sampling methods were employed for the data collection and selection of the participants, and semistructured interviews were held. During the data analysis, 17 categories emerged and these were categorized into three themes: "task generation", "assertiveness behavior", and "executive agents". From the participants' experiences, assertiveness theory emerged as being fundamental to the development of a schematic model describing nursing leadership behaviors. From another aspect, religious beliefs also played a fundamental role in Iranian nursing leadership assertiveness. It was concluded that bringing a change in the current support from top managers and improving self-learning are required in order to enhance the assertiveness of the nursing leaders in Iran.

    2008-06-01

    Full Text Available Grounded theory is a systematic methodology for the collection and analysis of data which was discovered by Glaser and Strauss in the 1960’s. The discovery of this method was first presented to the academic community in their book ‘The Discovery of Grounded Theory’ (1967 which still remains a primary point of reference for those undertaking qualitative research and grounded theory in particular. This powerful research method has become very popular in some research domains; whilst increasing in popularity it is still less prevalent in the field of organisational and management research particularly in its original form. This self reflexive paper sets out to explore the possibilities for this imbalance which takes the discussion onto the areas of methodological adaptation and training. It also enters the debate about access to research subjects and provides a succinct argument supporting the notion that grounded theory should simply be viewed as a method that develops empirically grounded conceptual theory.

    Yow, J.L. Jr.; Goodman, R.E.

    1985-09-01

    Discontinuities in a rock mass can intersect an excavation surface to form discrete blocks (keyblocks) which can be unstable. Once a potentially unstable block is identified, the forces affecting it can be calculated to assess its stability. The normal and shear stresses on each block face before displacement are calculated using elastic theory and are modified in a nonlinear way by discontinuity deformations as the keyblock displaces. The stresses are summed into resultant forces to evaluate block stability. Since the resultant forces change with displacement, successive increments of block movement are examined to see whether the block ultimately becomes stable or fails. Two-dimensional (2D) and three-dimensional (3D) analytic models for the stability of simple pyramidal keyblocks were evaluated. Calculated stability is greater for 3D analyses than for 2D analyses. Calculated keyblock stability increases with larger in situ stress magnitudes, larger lateral stress ratios, and larger shear strengths. Discontinuity stiffness controls blocks displacement more strongly than it does stability itself. Large keyblocks are less stable than small ones, and stability increases as blocks become more slender

    This paper describes the methodological and theoretical context and underpinnings of a study that examined community psychiatric nurses' work with family caregivers of older people with depression. The study used grounded theory research methods, with its theoretical foundations drawn from symbolic interactionism. The aims of the study were to describe and conceptualize the processes involved when community nurses work and interact with family caregivers and to develop an explanatory theory of these processes. This paper begins with an explanation of the rationale for using grounded theory as the method of choice, followed by a discussion of the theoretical underpinnings of the study, including a brief summary of the nature and origins of symbolic interactionism. Key premises of symbolic interactionism regarded as central to the study are outlined and an analytical overview of the grounded theory method is provided. The paper concludes with a commentary on some of the issues and debates in the use of grounded theory in nursing research. The main purpose of this paper is to provide a methodical and critical review of symbolic interactionism and grounded theory that can help readers, particularly those who are intending to use grounded theory, better understand the processes involved in applying this method to their research.

    2013-01-01

    To explore the evolution of grounded theory and equip the reader with a greater understanding of the diverse conceptual positioning that is evident in the methodology. Grounded theory was developed during the modernist phase of research to develop theories that are derived from data and explain human interaction. Its philosophical foundations derive from symbolic interactionism and were influenced by a range of scholars including Charles Darwin and George Mead. Rather than a rigid set of rules and procedures, grounded theory is a way of conceptualising data. Researchers demonstrate a range of perspectives and there is significant variation in the way the methodology is interpreted and executed. Some grounded theorists continue to align closely with the original post-positivist view, while others take a more constructivist approach. Although the diverse interpretations accommodate flexibility, they may also result in confusion. The grounded theory approach enables researchers to align to their own particular world view and use methods that are flexible and practical. With an appreciation of the diverse philosophical approaches to grounded theory, researchers are enabled to use and appraise the methodology more effectively.

    Parenteral nutrition (PN) provides nourishment and hydration as an intravenous infusion to patients with intestinal failure (IF). The aim of the study is to generate theory that explains the experiences of adult patients living with home parenteral nutrition (HPN) and complex medication regimens. A grounded theory methodology was used to explore the experiences of twelve patients receiving HPN. A semi-structured interview was conducted and recorded in each participant's home setting. Each interview was transcribed verbatim. The simultaneous process of data collection and analysis was followed reflecting the principles of the constant comparative approach. A total of 15 patients gave written consent, with 12 of them agreeing to be interviewed. All the participants had previously undergone surgery as a result of chronic ill health or sudden illness. Analysis revealed two core categories: stoma and HPN, and these were supported by the subcategories: maintaining stoma output, access to toilets, managing dietary changes, maintaining the HPN infusion routine, access to technical help to set up an HPN infusion, mobility with HPN equipment and general health changes. The strategy of living with loss was demonstrated by all the participants, and this was supported by the action strategies of maintaining daily activities and social interactions. This study generates new understanding and insight into the views and experiences of patients receiving HPN in the UK. The findings from these participants have been shown to resonate with the Kubler-Ross Model [1] of the five stages of grief. The theory of living with loss was generated by the use of a grounded theory methodology. This small scale exploratory study reveals opportunities for improvements in practice to be considered by the nutrition support team (NST) and other healthcare professionals involved in the patient's hospital stay prior to discharge on HPN.

    1988-01-01

    In recent years the interplay between model theory and other branches of mathematics has led to many deep and intriguing results. In this, the first book on the topic, the theme is the interplay between model theory and the theory of modules. The book is intended to be a self-contained introduction to the subject and introduces the requisite model theory and module theory as it is needed. Dr Prest develops the basic ideas concerning what can be said about modules using the information which may be expressed in a first-order language. Later chapters discuss stability-theoretic aspects of module

  4. Empirical and pragmatic adequacy of grounded theory: Advancing nurse empowerment theory for nurses' practice.

    Udod, Sonia A; Racine, Louise

    2017-12-01

    To draw on the findings of a grounded theory study aimed at exploring how power is exercised in nurse-manager relationships in the hospital setting, this paper examines the empirical and pragmatic adequacy of grounded theory as a methodology to advance the concept of empowerment in the area of nursing leadership and management. The evidence on staff nurse empowerment has highlighted the magnitude of individual and organisational outcomes, but has not fully explicated the micro-level processes underlying how power is exercised, shared or created within the nurse-manager relationship. Although grounded theory is a widely adopted nursing research methodology, it remains less used in nursing leadership because of the dominance of quantitative approaches to research. Grounded theory methodology provides the empirical and pragmatic relevance to inform nursing practice and policy. Grounded theory is a relevant qualitative approach to use in leadership research as it provides a fine and detailed analysis of the process underlying complexity and bureaucracy. Discursive paper. A critical examination of the empirical and pragmatic relevance of grounded theory by (Corbin & Strauss, , ) as a method for analysing and solving problems in nurses' practice is provided. This paper provides evidence to support the empirical and pragmatic adequacy of grounded theory methodology. Although the application of the ontological, epistemological and methodological assumptions of grounded theory is challenging, this methodology is useful to address real-life problems in nursing practice by developing theoretical explanations of nurse empowerment, or lack thereof, in the workplace. Grounded theory represents a relevant methodology to inform nursing leadership research. Grounded theory is anchored in the reality of practice. The strength of grounded theory is to provide results that can be readily applied to clinical practice and policy as they arise from problems that affect practice and that

  5. [The grounded theory as a methodological alternative for nursing research].

    dos Santos, Sérgio Ribeiro; da Nóbrega, Maria Miriam

    2002-01-01

    This study presents a method of interpretative and systematic research with appliance to the development of studies in nursing called "the grounded theory", whose theoretical support is the symbolic interactionism. The purpose of the paper is to describe the grounded theory as an alternative methodology for the construction of knowledge in nursing. The study highlights four topics: the basic principle, the basic concepts, the trajectory of the method and the process of analysis of the data. We conclude that the systematization of data and its interpretation, based on social actors' experience, constitute strong subsidies to generate theories through this research tool.

    To offer a unique contribution to the evolving debate around the use of the telephone during semistructured interview by drawing on interviewees' reflections on telephone interview during a grounded theory study. The accepted norm for qualitative interviews is to conduct them face-to-face. It is typical to consider collecting qualitative data via telephone only when face-to-face interview is not possible. During a grounded theory study, exploring users' experiences with overnight mask ventilation for sleep apnoea, the authors selected the telephone to conduct interviews. This article reports participants' views on semistructured interview by telephone. An inductive thematic analysis was conducted on data pertaining to the use of the telephone interview in a grounded theory study. The data were collected during 4 months of 2011 and 6 months in 2014. The article presents an inductive thematic analysis of sixteen participants' opinions about telephone interviewing and discusses these in relation to existing literature reporting the use of telephone interviews in grounded theory studies. Overall, participants reported a positive experience of telephone interviewing. From each participants reports we identified four themes from the data: being 'phone savvy; concentrating on voice instead of your face; easy rapport; and not being judged or feeling inhibited. By drawing on these data, we argue that the telephone as a data collection tool in grounded theory research and other qualitative methodologies need not be relegated to second best status. Rather, researchers can consider telephone interview a valuable first choice option. © 2015 John Wiley & Sons Ltd.

    2017-03-01

    Although empathy is one of most robust predictors of client outcome, there is little consensus about how best to conceptualize this construct. The aim of the present research was to investigate clients' perceptions and in-session experiences of empathy. Semi-structured, video-assisted interpersonal process recall interviews were used to collect data from nine clients receiving individual psychotherapy at a university psychology clinic. Grounded theory analysis yielded a model consisting of three clusters: (1) relational context of empathy (i.e., personal relationship and professional relationship), (2) types of empathy (i.e., psychotherapists' cognitive empathy, psychotherapists' emotional empathy, and client attunement to psychotherapist), and (3) utility of empathy (i.e., process-related benefits and client-related benefits). These results suggest that empathy is a multi-dimensional, interactional process that affects-and is affected by-the broader relationship between client and psychotherapist.

    Full Text Available This Grounded Theory study describes the process by which older persons “become” volunteers. Forty interviews of older persons who volunteered for Habitat for Humanity were subjected to secondary content analysis to uncover the process of “becoming” a volunteer. “Helping out” (core category for older volunteers occurs within the context of “continuity”, “commitment” and “connection” which provide motivation for volunteering. When a need arises, older volunteers “help out” physically and financially as health and resources permit. Benefits described as “blessings” of volunteering become motivators for future volunteering. Findings suggest that older volunteering is a developmental process and learned behavior which should be fostered in older persons by personally inviting them to volunteer. Intergenerational volunteering projects will allow older persons to pass on knowledge and skills and provide positive role modeling for younger volunteers.

    2018-06-01

    Grounded theory analysis of secondary school staff and pupil perceptions about the barriers to preventative work for adolescent self-harm within the secondary school setting in Wales. Qualitative and grounded theory. Two secondary schools in Wales were purposefully sampled for variation. Four group interviews took place using qualitative research methods (Participatory Rapid Appraisal) with six school-based professionals and six students aged more than 16 years. Three pupil participants had long-term experience themselves of self-harming behaviours; all the remaining participants had encountered pupils who self-harmed. The research interviews were transcribed verbatim, generating school context-dependent information. This was analysed through the logic of abduction using the constant comparative grounded theory method because of its ability to focus on axial coding for context. The ontology that shaped this work was critical realism within a public health paradigm. A theoretical model of stigma resulted from the grounded theory analytical process, specifically in relation to staff and student perceptions about adolescent self-harm within the institutional context. This meant that social-based behaviours in the secondary school setting centred on the topic and behaviour of adolescent self-harm were structured by stigma. The findings of this study offer an explanation on the exclusion of adolescent self-harm from preventative work in secondary schools. The stigma model demonstrates that adolescent self-harm is excluded from the socio-cultural norms of the institutional setting. Applying the UK Equality Act (2010), this is discrimination. Further research on the institutional-level factors impacting adolescent self-harm in the secondary school context in England and Wales is now urgently needed.

  11. Ground-water models: Validate or invalidate

    Science.gov (United States)

    Bredehoeft, J.D.; Konikow, Leonard F.

    1993-01-01

    The word validation has a clear meaning to both the scientific community and the general public. Within the scientific community the validation of scientific theory has been the subject of philosophical debate. The philosopher of science, Karl Popper, argued that scientific theory cannot be validated, only invalidated. Popper’s view is not the only opinion in this debate; however, many scientists today agree with Popper (including the authors). To the general public, proclaiming that a ground-water model is validated carries with it an aura of correctness that we do not believe many of us who model would claim. We can place all the caveats we wish, but the public has its own understanding of what the word implies. Using the word valid with respect to models misleads the public; verification carries with it similar connotations as far as the public is concerned. Our point is this: using the terms validation and verification are misleading, at best. These terms should be abandoned by the ground-water community.

    Full Text Available Background: Traffic accidents are among major causes of death all over the world. In Iran, it has become a social problem, with lots of people involved in; and the youth include the most victims of traffic accidents. Objectives: The main objective of this research is to review the experience of the youth (18–24 years old in Tehran, Iran with traffic accidents, and to develop a model to specify the factors. Methods: This study is based on Grounded Theory, in which a sample group of 50 young people, 18–24 years old, in Tehran, Iran, were selected and interviewed, using stratified purposive and snowball sampling method. Data is mainly collected by interviewing the youth in 7 key topics. To analyze the data, Grounded Theory is used through production of themes, components and concepts. Results: There are 11 general components for traffic accidents according to the ideas of the youth which will come in 3 categories including: individual factors (emotions, sensory-motor skills, and physical-mental health; environmental factors (road and traffic problems, a companion, using cellphone, or front individual, including carless drivers or passersby; and underlying factors (gender, legal and cultural infrastructures. And finally, the core category of carelessness, which is the leading cause in traffic accidents.    Conclusion: The findings indicate that a chain of various factors may cause traffic accidents with lots of devastating consequences. It is therefore necessary to modify driving culture, to internalize the attitude of caution, to use polyhedral strategies, and to apply them all correctly.

    2000-01-01

    Optimization of the parameters of a future linear collider requires comprehensive models of ground motion. Both general models of ground motion and specific models of the particular site and local conditions are essential. Existing models are not completely adequate, either because they are too general, or because they omit important peculiarities of ground motion. The model considered in this paper is based on recent ground motion measurements performed at SLAC and at other accelerator laboratories, as well as on historical data. The issues to be studied for the models to become more predictive are also discussed

    2017-01-01

    Bisexual people constitute the largest sexual minority group in North America and experience significant mental health disparities in relation to heterosexuals, gays, and lesbians. In this article, we will examine the process and experience of help seeking among bisexuals. This was a community-based study that collected qualitative interview data from 41 diverse bisexual people from across Ontario, Canada. We analyzed the interview data using grounded theory and constructed an understanding of bisexuals' experiences of help seeking. We have conceptualized an overarching model that illustrates 4 interrelated stages: (a) the consideration of services, (b) the process of finding services, (c) barriers and facilitators to accessing services, and (d) experience of service utilization. This model is nonlinear, in that participants do not necessarily move through stages in sequence. Although many stages are experienced at the individual level, they are simultaneously informed by multiple factors at interpersonal and system levels. Our findings suggest a need for interventions at the policy, service and provider levels to improve accessibility of culturally competent services for this population. Understanding the mental health experiences of bisexual people will allow mental health professionals to build competencies working with this population and thereby contribute to a reduction in mental health disparities.

    2012-06-01

    Full Text Available This paper draws on the experiences of two researchers and discusses how they conducted a secondary data analysis using classic grounded theory. The aim of the primary study was to explore first-time parents’ postnatal educational needs. A subset of the data from the primary study (eight transcripts from interviews with fathers was used for the secondary data analysis. The objectives of the secondary data analysis were to identify the challenges of using classic grounded theory with secondary data and to explore whether the re-analysis of primary data using a different methodology would yield a different outcome. Through the process of re-analysis a tentative theory emerged on ‘developing competency as a father’. Challenges encountered during this re-analysis included the small dataset, the pre-framed data, and limited ability for theoretical sampling. This re-analysis proved to be a very useful learning tool for author 1(LA, who was a novice with classic grounded theory.

    2016-04-01

    The purpose of this qualitative study was to explore the workplace bullying experience of Korean nurses. Participants were twenty current or former hospital nurses who had experienced workplace bullying. Data were collected through focus group and individual in-depth interviews from February to May, 2015. Theoretical sampling method was applied to the point of theoretical saturation. Transcribed interview contents were analyzed using Corbin and Strauss's grounded theory method. A total of 110 concepts, 48 sub-categories, and 17 categories were identified through the open coding process. As a result of axial coding based on the paradigm model, the central phenomenon of nurses' workplace bullying experience was revealed as 'teaching that has become bullying', and the core category was extracted as 'surviving in love-hate teaching' consisting of a four-step process: confronting reality, trial and error, relationship formation, and settlement. The relationship formation was considered to be the key phase to proceed to the positive settlement phase, and the participants utilized various strategies such as having an open mind, developing human relationships, understanding each other in this phase. The in-depth understanding of the workplace bullying experience has highlighted the importance of effective communication for cultivating desirable human relationships between nurses.

    2011-07-01

    The study aim was to identify the process underlying the performance of agency for urban-dwelling Aboriginal women in contemporary Australian society with a view to promoting social change for Aboriginal people. Grounded theory methods were used in the conduct of 20 life history narrative interviews with Aboriginal women from across fourteen different language groups. Analysis identified a specific ecological model of Aboriginal women's empowerment, defined as "becoming empowered". "Performing Aboriginality" was identified as the core category and encompassed the women's concern for carving out a fulfilling life and carrying out their perceived responsibilities as Aboriginal women. While confirming much of the extant literature on empowerment, the analysis also offered unique contributions--a spiritual sensibility, cultural competence and an ethics of care and morality. This sheds new light on the creative ways in which Aboriginal women "disrupt" discourses and create alternate modes of existence. The findings have implications for improving quality of life for Aboriginal people by informing the practical development and delivery of social and health policies and programs.

    2010-01-01

    Radiotherapy practitioners may be best placed to undertake qualitative research within the context of cancer, due to specialist knowledge of radiation treatment and sensitivity to radiotherapy patient's needs. The grounded theory approach to data collection and analysis is a unique method of identifying a theory directly based on data collected within a clinical context. Research for radiotherapy practitioners is integral to role expansion within the government's directive for evidence-based practice. Due to the paucity of information on qualitative research undertaken by radiotherapy radiographers, this article aims to assess the potential impact of qualitative research on radiotherapy patient and service outcomes.

    This study aimed to explore the experiences of nursing students being trained to perform vaccinations. The grounded theory method was applied to gather information through semi-structured interviews. The participants included 14 undergraduate nursing students in their fifth and eighth semesters of study in a nursing school in Iran. The information was analyzed according to Strauss and Corbin's method of grounded theory. A core category of experiential learning was identified, and the following eight subcategories were extracted: students' enthusiasm, vaccination sensitivity, stress, proper educational environment, absence of prerequisites, students' responsibility for learning, providing services, and learning outcomes. The vaccination training of nursing students was found to be in an acceptable state. However, some barriers to effective learning were identified. As such, the results of this study may provide empirical support for attempts to reform vaccination education by removing these barriers.

    2018-05-23

    This systematic review aimed at appraising the methodological rigor of grounded theory research published in the field of physiotherapy to assess how the methodology is understood and applied. A secondary aim was to provide research implications drawn from the findings to guide future grounded theory methodology (GTM) research. A systematic search was conducted in MEDLINE, CINHAL, SPORT Discus, Science Direct, PubMed, Scopus, and Web of Science to identify studies in the field of physiotherapy that reported using GTM and/or methods in the study title and/or abstract. The descriptive characteristics and methodological quality of eligible studies were examined using grounded theory methodology assessment guidelines. The review included 68 studies conducted between 1998 and 2017. The findings showed that GTM is becoming increasingly used by physiotherapy researchers. Thirty-six studies (53%) demonstrated a good understanding and appropriate application of GTM. Thirty-two studies (47%) presented descriptive findings and were considered to be of poor methodological quality. There are several key tenets of GTM that are integral to the iterative process of qualitative theorizing and need to be applied throughout all research practices including sampling, data collection, and analysis.

    2013-01-01

    To discuss the creation of a substantive theory using grounded theory. This article provides an example of generating theory from a study of mental health promotion at a high school in Finland. Grounded theory is a method for creating explanatory theory. It is a valuable tool for health professionals when studying phenomena that affect patients' health, offering a deeper understanding of nursing methods and knowledge. Interviews with school employees, students and parents, and verbal responses to the 'school wellbeing profile survey', as well as working group memos related to the development activities. Participating children were aged between 12 and 15. The analysis was conducted by applying the grounded theory method and involved open coding of the material, constant comparison, axial coding and selective coding after identifying the core category. The analysis produced concepts about mental health promotion in school and assumptions about relationships. Grounded theory proved to be an effective means of eliciting people's viewpoints on mental health promotion. The personal views of different parties make it easier to identify an action applicable to practice.

    Reay, Gudrun; Bouchal, Shelley Raffin; A Rankin, James

    2016-09-01

    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.

  13. A Grounded Theory Analysis of Introductory Computer Science Pedagogy

    Directory of Open Access Journals (Sweden)

    2011-12-01

    Full Text Available Planning is a critical, early step on the path to successful program writing and a skill that is often lacking in novice programmers. As practitioners we are continually searching for or creating interventions to help our students, particularly those who struggle in the early stages of their computer science education. In this paper we report on our ongoing research of novice programming skills that utilizes the qualitative research method of grounded theory to develop theories and inform the construction of these interventions. We describe how grounded theory, a popular research method in the social sciences since the 1960’s, can lend formality and structure to the common practice of simply asking students what they did and why they did it. Further, we aim to inform the reader not only about our emerging theories on interventions for planning but also how they might collect and analyze their own data in this and other areas that trouble novice programmers. In this way those who lecture and design CS1 interventions can do so from a more informed perspective.

  14. Becoming Selfless: A Grounded Theory of Commitment to Service

    Directory of Open Access Journals (Sweden)

    Roland Nino L. Agoncillo

    2014-05-01

    Full Text Available This study focuses on the substantive area of commitment to service in the community of educational partners in the Philippines. Educational partners are lay people who assist religious organizations in the field of education, and in the Philippines, about 96 percent of educational partners are in Lasallian schools and organizations. Educational partners are young professionals, volunteers between the ages of 24-39 who strive to live the teachings of St. John Baptist De La Salle. The volunteers aim to generate a spirit of service, a sense of mission to the youth. By using a classic Grounded Theory approach, the theory of becoming selfless was generated. The theory explains the stages educational partners undergo when resolving their organizational commitment to service. Organizational commitment is the psychological attachment, involvement and identification of the individual to the organization. Becoming selfless provides a theoretical focal point to better understand the complexity of commitment.

    The response of very stiff structures, such as nuclear reactor buildings, to earthquake ground motion is significantly affected by radiation damping due to the soil-structure interaction. The radiation damping can be computed by vibration admittance theory or dynamical ground compliance theory. In order to apply the values derived from these theories to the practical problems, comparative studies between theoretical results and experimental results concerning the soil-structure interaction, especially if the ground is rock, are urgently needed. However, experimental results for rock are less easily obtained than theoretical ones. The purpose of this paper is to describe the harmonic excitation tests of a model foundation on rock and to describe the results of comparative studies. (orig./HP)

    Coeliac disease can be controlled only through adherence to a gluten-free diet. This diet is highly restrictive and can be challenging to maintain. It has been linked with elevated levels of psychological distress, including depression, anxiety and social phobia. Narratives on living with coeliac disease were written by 130 adult members of Coeliac UK (mean age 52.7 years; mean time since diagnosis 10.2 years; 67% sample female; 28% male). Qualitative analysis using grounded theory methods identified five key categories: living with widespread ignorance; social invisibility; creating a coeliac community; a changed identity; grief - and accepting the trade-off. A psychosocial model of living with coeliac disease was constructed from the findings, the central category of which was the changed identity of those diagnosed with the condition. Grief was experienced in relation to a loss of the former diet, changed personal and social identities, loss of social confidence and loss of social activities. Grief was generally mitigated over time as adjustments were made to changes in identity and lifestyle. Creating (or becoming part of) a coeliac community was a strategy enabling those with coeliac disease to re-establish their identities and increase social recognition and acceptance of the condition. Gluten-free living entails a substantial restriction of food choice. The losses and changes entailed impact on the personal and social identities of those living with coeliac disease, and on the behaviour of others towards them. Psychosocial interventions focussed on facilitating coping and adjustment may benefit those experiencing difficulties. © 2013 The Authors Journal of Human Nutrition and Dietetics © 2013 The British Dietetic Association Ltd.

    2014-12-01

    The labor ward is an important and challenging learning area for midwifery students. It is there the students learn in authentic complex situations, in intimate situations, with potential risk for the life and health of mothers and their babies. The aim of this study was to explore the main concern expressed by midwifery students in labor wards and how they handled this concern. A longitudinal study based on grounded theory methodology was used. The participants were 10 postgraduate midwifery students, from a University College in Norway. Data were gathered and analyzed throughout the 2-year postgraduate program, in the students first, third and fourth semesters. Every student was interviewed three times in a total of 15 single and three focus-group sessions. The grounded theory of "building relationships" explains how students dealt with their main concern: "how to gain access to learning experiences". This theory consisted of three strategies; a) controlling vulnerability, b) cultivating trust and c) obtaining acceptance. Clarifying discussions involving midwives and students may facilitate the process of building relationships and contribute to confident learning. Students appreciate it when the midwives initiate discussions about acute situations and state that a novice may perceive labor and childbirth as more frightening than an experienced midwife would.

    2017-01-01

    Background Psychiatry has faced significant criticism for overreliance on the Diagnostic and Statistical Manual of Mental Disorders (DSM) and medications with purported disregard for empathetic, humanistic interventions. Aims To develop an empirically based qualitative theory explaining how psychiatrists use empathy in day-to-day practice, to inform practice and teaching approaches. Method This study used constructivist grounded theory methodology to ask (a) ‘How do psychiatrists understand and use empathetic engagement in the day-to-day practice of psychiatry?’ and (b) ‘How do psychiatrists learn and teach the skills of empathetic engagement?’ The authors interviewed 17 academic psychiatrists and 4 residents and developed a theory by iterative coding of the collected data. Results This constructivist grounded theory of empathetic engagement in psychiatric practice considered three major elements: relational empathy, transactional empathy and instrumental empathy. As one moves from relational empathy through transactional empathy to instrumental empathy, the actions of the psychiatrist become more deliberate and interventional. Conclusions Participants were described by empathy-based interventions which are presented in a theory of ’empathetic engagement’. This is in contrast to a paradigm that sees psychiatry as purely based on neurobiological interventions, with psychotherapy and interpersonal interventions as completely separate activities from day-to-day psychiatric practice.

    This paper offers a critical reflection upon the use of a grounded theory approach within a doctoral study. As well as providing an outline of grounded theory, it begins by noting the existence of some powerful critiques of a grounded theory approach, in particular around the key concepts of ‘theory’, ‘discovery’ and ‘ground’. It is argued that, in some cases, grounded theory struggles to counter these challenges, especially in its ‘purist’ forms. However, with reference to research carried o...

    Mills, Jane; Chapman, Ysanne; Bonner, Ann; Francis, Karen

    2007-04-01

    Our aim in this paper is to explain a methodological/methods package devised to incorporate situational and social world mapping with frame analysis, based on a grounded theory study of Australian rural nurses' experiences of mentoring. Situational analysis, as conceived by Adele Clarke, shifts the research methodology of grounded theory from being located within a postpositivist paradigm to a postmodern paradigm. Clarke uses three types of maps during this process: situational, social world and positional, in combination with discourse analysis. During our grounded theory study, the process of concurrent interview data generation and analysis incorporated situational and social world mapping techniques. An outcome of this was our increased awareness of how outside actors influenced participants in their constructions of mentoring. In our attempts to use Clarke's methodological package, however, it became apparent that our constructivist beliefs about human agency could not be reconciled with the postmodern project of discourse analysis. We then turned to the literature on symbolic interactionism and adopted frame analysis as a method to examine the literature on rural nursing and mentoring as secondary form of data. While we found situational and social world mapping very useful, we were less successful in using positional maps. In retrospect, we would argue that collective action framing provides an alternative to analysing such positions in the literature. This is particularly so for researchers who locate themselves within a constructivist paradigm, and who are therefore unwilling to reject the notion of human agency and the ability of individuals to shape their world in some way. Our example of using this package of situational and social worlds mapping with frame analysis is intended to assist other researchers to locate participants more transparently in the social worlds that they negotiate in their everyday practice.

    2018-01-01

    The aim of this study was to develop an explanatory theory on the lives of young people with asthma, issues affecting them and the impact of asthma on their day-to-day lives. Accommodating Interruptions is a theory that explains young people's concerns about living with asthma. Although national and international asthma management guidelines exist, it is accepted that the symptom control of asthma among the young people population is poor. This study was undertaken using Classic Grounded Theory. Data were collected through in-depth interviews and clinic consultations with young people aged 11-16 years who had asthma for over 1 year. Data were also collected from participant diaries. Constant comparative analysis, theoretical coding and memo writing were used to develop the substantive theory. The theory explains how young people resolve their main concern of being restricted by Accommodating Interruptions in their lives. They do this by assimilating behaviours in balance finding, moderating influence, fitting in and assuming control minimising the effects of asthma on their everyday lives. The theory of Accommodating Interruptions explains young people's asthma management behaviours in a new way. It allows us to understand how and why young people behave the way they do because they want to participate and be included in everyday activities, events and relationships. The theory adds to the body of knowledge on how young people with asthma live their day-to-day lives and it challenges some existing viewpoints in the literature regarding their behaviours. The findings have implications for developing services to support young people in a more meaningful way as they accommodate the interruptions associated with asthma in their lives. © 2017 John Wiley & Sons Ltd.

    Ground motion prediction models (GMPMs) relate ground motion intensity measures to variables describing earthquake source, path, and site effects. Estimation of expected ground motion is a fundamental earthquake hazard assessment. The most commonly used parameter for attenuation relation is peak ground acceleration or spectral acceleration because this parameter gives useful information for Seismic Hazard Assessment. Since 2003 development of Georgian Digital Seismic Network has started. In this study new GMP models are obtained based on new data from Georgian seismic network and also from neighboring countries. Estimation of models is obtained by classical, statistical way, regression analysis. In this study site ground conditions are additionally considered because the same earthquake recorded at the same distance may cause different damage according to ground conditions. Empirical ground-motion prediction models (GMPMs) require adjustment to make them appropriate for site-specific scenarios. However, the process of making such adjustments remains a challenge. This work presents a holistic framework for the development of a peak ground acceleration (PGA) or spectral acceleration (SA) GMPE that is easily adjustable to different seismological conditions and does not suffer from the practical problems associated with adjustments in the response spectral domain.

    2014-06-01

    Full Text Available Classic grounded theory (CGT was used to identify a main concern of online students in higher education. One of the main impediments to studying online is a sense of isolation and lack of access to support systems as students navigate through complex requirements of their online programs. Hypothetical probability statements illustrate the imbalance between heightened needs of virtual learners and perceived inadequate support provided by educational institutions. The core variable, marshaling resources, explains how peer supports sustain motivation toward successful program completion. Understanding the critical contribution virtual interpersonal networks make towards maximizing resources by group problem solving is a significant aspect of this theory.

    2007-03-01

    Recently there has been a large volume of research on persecutory paranoia. Evidence has emerged for the role of social factors in the development of paranoia. There have, however, been no studies that have collaborated with users to develop an experiential perspective on paranoia. This study used a social constructionist version of grounded theory to develop an experiential perspective on persecutory paranoia. Ten individuals who had experience of persecutory paranoia were interviewed. The interviews were transcribed and analysed using the grounded theory method. A core process of fear and vulnerability was constructed. Subcategories of confusion and uncertainty, and self under attack contributed to the core process. These processes led to an engaging of the safety systems. Subthemes of these categories were identified. Many of these factors interacted to create the complex and dynamic experience of paranoia. Participants were often responding to genuinely frightening experiences but were also attacking themselves. Paranoia evolved as a mechanism of keeping oneself safe in dangerous situations. The need to negotiate a shared meaning of paranoia with users is emphasized. Direction for future research was discussed.

    2016-03-01

    Full Text Available A qualitative study was conducted to examine the philosophy of technology of K-12 technology leaders, and explore the influence of their thinking on technology decision making. The research design aligned with CORBIN and STRAUSS grounded theory methods, and I proceeded from a research paradigm of critical realism. The subjects were school technology directors and instructional technology specialists, and data collection consisted of interviews and a written questionnaire. Data analysis involved the use of grounded theory methods including memo writing, open and axial coding, constant comparison, the use of purposive and theoretical sampling, and theoretical saturation of categories. Three broad philosophy of technology views were widely held by participants: an instrumental view of technology, technological optimism, and a technological determinist perspective that saw technological change as inevitable. Technology leaders were guided by two main approaches to technology decision making, represented by the categories Educational goals and curriculum should drive technology, and Keep up with technology (or be left behind. The core category and central phenomenon that emerged was that technology leaders approached technology leadership by placing greater emphasis on keeping up with technology, being influenced by an ideological orientation to technological change, and being concerned about preparing students for a technological future.

    2017-12-01

    Introduction: Professional socialization is a critical aspect of nursing students' development, which begins with entry into the nursing program and continues when their professional practice begins. The aim of this study was to explore the socialization of Iranian BSN students in the nursing profession. Methods: An exploratory qualitative approach utilizing Straussian version of the grounded theory (1998) method was used. Individual in-depth semi-structured interviews were undertaken with 14 participants chosen from two large nursing schools in an urban area through purposive and theoretical sampling. The data were analyzed, using the constant comparative method. Results: Five main categories and eleven subcategories emerged and integrated around one core category. Professional metamorphosis as the core variable was a complex and interrelated process (consisting of three stages: dependence, disintegration, and integration) with dynamic, ongoing, and personal features influenced by professional and extra-professional context. The students assumed a passive role in the initial of their studies. However, during the last year of the educational program, they gradually involved actively in dealing with own personal and professional issues. Conclusion: This study introduced "professional metamorphosis of BSN students" as a substantive grounded theory in the socio-cultural context of the health care system in Iran. During this process, students move from outsider personal position to insider professional position. The nurse educators and administrators may develop effective educational interventions to promote professional socialization of students with an understanding of the promoting and driving forces influencing socialization.

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

    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. © The Author(s) 2015.

In the third edition of their seminal text, Basics of Qualitative Research: Techniques and Procedures for Developing Grounded Theory, the authors present 16 assumptions that underpin their conception of grounded theory methodology. The assumptions stem from a symbolic interactionism perspective of social life, including the themes of meaning, action and interaction, self and perspectives. As research design incorporates both methodology and methods, the authors aim to expose the linkages between the 16 assumptions and essential grounded theory methods, highlighting the application of the latter in light of the former. Analyzing the links between symbolic interactionism and essential grounded theory methods provides novice researchers and researchers new to grounded theory with a foundation from which to design an evolved grounded theory research study.

    Male circumcision reduces the risk of female-to-male transmission of human immunodeficiency virus (HIV) and is being explored for HIV prevention in Papua New Guinea (PNG). PNG has a concentrated HIV epidemic which is largely heterosexually transmitted. There are a diverse range of male circumcision and penile modification practices across PNG. Exploring the implications of male circumcision for women in PNG is important to inform evidence-based health policy that will result in positive, intended consequences. The transformational grounded theory study incorporated participatory action research and decolonizing methodologies. In Phase One, an existing data set from a male circumcision study of 861 male and 519 female participants was theoretically sampled and analyzed for women's understanding and experience of male circumcision. In Phase Two of the study, primary data were co-generated with 64 women in seven interpretive focus group discussions and 11 semi-structured interviews to develop a theoretical model of the processes used by women to manage the outcomes of male circumcision. In Phase Three participants assisted to refine the developing transformational grounded theory and identify actions required to improve health. Many women know a lot about male circumcision and penile modification and the consequences for themselves, their families and communities. Their ability to act on this knowledge is determined by numerous social, cultural and economic factors. A transformational grounded theory was developed with connecting categories of: Women Know a Lot, Increasing Knowledge; Increasing Options; and Acting on Choices. Properties and dimensions of each category are represented in the model, along with the intervening condition of Safety. The condition of Safety contextualises the overarching lived realty for women in PNG, enables the inclusion of men in the transformational grounded theory model, and helps to explain relationships between men and women.

    Full Text Available 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.

    2012-09-01

    Full Text Available The genesis and development of grounded theory method (GTM is evaluated with reference to sociology's attempt to demarcate exclusive referents of inquiry. The links of objectivist GTM to positivistic terminology and to the natural scientific distinction from "common sense" are explored. It is then considered how the biological sciences have prompted reorientation towards constructivist GTM, underpinned by the metaphysics of social constructionism. GTM has been shaped by the endeavor to attain the sense of exactitude associated with positivism, whilst also seeking exclusive referents of inquiry that are distinct from the empirical realm of the natural sciences. This has generated complex research techniques underpinned by tortuous methodological debate: eschewing the perceived requirement to define and defend an academic niche could help to facilitate the development of a more useful and pragmatic orientation to qualitative social research.

    2014-12-01

    Full Text Available This study focuses on the substantive area of business administration using the classic grounded theory method. Business administration is mostly driven by political games between top-level corporate managers. The main concern of the managers I met was that they wanted to be more politically successful. For them, success meant being able to change regularly the course of decisions and action within their firm. The study led to the emergence of a core variable called political intelligentizing. Political intelligentizing explains the recurrent main concern that these managers have to resolve, and it explains the competences managers have to combine to succeed regularly in organisational politics. They resolve their main problem through political intelligentizing which consists in acquiring, developing and combining six specific skills: time matching, rhetorical fitting, silence juggling, strategic forward-thinking, strategic interacting and relationing.

  1. Are There Two Methods of Grounded Theory? Demystifying the Methodological Debate

    Directory of Open Access Journals (Sweden)

    Cheri Ann Hernandez, RN, Ph.D., CDE

    2008-06-01

    Full Text Available Grounded theory is an inductive research method for the generation of substantive or formal theory, using qualitative or quantitative data generated from research interviews, observation, or written sources, or some combination thereof (Glaser & Strauss, 1967. In recent years there has been much controversy over the etiology of its discovery, as well as, the exact way in which grounded theory research is to be operationalized. Unfortunately, this situation has resulted in much confusion, particularly among novice researchers who wish to utilize this research method. In this article, the historical, methodological and philosophical roots of grounded theory are delineated in a beginning effort to demystify this methodological debate. Grounded theory variants such as feminist grounded theory (Wuest, 1995 or constructivist grounded theory (Charmaz, 1990 are beyond the scope of this discussion.

    Full Text Available Background: Physical activity has demonstrated benefits in cancer-related fatigue and physical functioning in early-stage cancer patients, however the role of physical activity at the end stage of cancer has not been established. To challenge positivist–empiricist assumptions, I am seeking to develop a new theoretical framework that is grounded in the advanced cancer patient’s experience of activity. Aim: To gain an in-depth understanding of the experience of activity and quality of life in advanced cancer patients. Objectives: (1 To explore the meaning of activity for advanced cancer patients in the context of their day-to-day life, (2 to elicit advanced cancer patients’ perceptions of activity with respect to their quality of life, and (3 to elicit advanced cancer patients’ views of barriers and facilitators to activity in the context of their day-to-day life. Study Design: A two-phase, cross-sectional, qualitative study will be conducted through the postpositivist lens of subtle realism and informed by the principles of grounded theory methods. Study Methods: Advanced cancer patients will be recruited through the outpatient department of a tertiary cancer center. For Phase one, participants will wear an activPAL™ activity monitor and fill out a daily record sheet for seven days duration. For Phase two, the activity monitor output and daily record sheets will be used as qualitative probes for face-to-face, semistructured interviews. Concurrent coding, constant comparative analysis, and theoretical sampling will continue with the aim of achieving as close as possible to theoretical saturation. Ethics and Discussion: Ethical and scientific approval will be obtained by all local institutional review boards prior to study commencement. The findings will generate new mid-level theory about the experience of activity and quality of life in advanced cancer patients and aid in the development of a new theoretical framework for designing

    2004-06-01

    Full Text Available The importance of understanding park planning issues and implementing planning strategies for ageing adults was the driving force for this study. Literature reviews have identified a variety of scholarly work from fields such as gerontology, psychology, sociology and economics, all of which provide valuable information regarding the special needs of ageing adults. Very few researchers, however, have investigated the leisure behaviours of older adults in outdoor recreation (Croskeys, Tinsley and Tinsley, 2002 and the use of grounded theory methodology has essentially been unexplored in this area. Ageing adults are projected to live more than 20 percent of their life in retirement (MRP, 1998, cited in Croskeys, Tinsley and Tinsley, 2002, allowing for an increased amount of discretionary time. This offers opportunities for ageing adults to participate in outdoor recreational activities and will undoubtedly increase their leisure time. However, with limited research in recreational needs and inclusion for older adults, it is difficult for park planners and administrators to meet the growing needs of this population. Therefore, this research is necessary in order to determine whether ageing adults are being accounted for in park and outdoor recreational planning. The objective of this study was to use grounded theory research methodology to identify and examine ageing adult needs in relation to outdoor leisure activities in a regional park setting. Ten Midwestern regional park visitors (aged 65-75 years old and four park employees were interviewed. Our research attempts to fill in the gaps between the perceptions of ageing park users and those of park planners, using a methodology that relies primarily on direct contact with park visitors.

  4. Is That a Real Theory or Did You Just Make It Up? Teaching Classic Grounded Theory

    Directory of Open Access Journals (Sweden)

    Odis E. Simmons, Ph.D.

    2010-06-01

    Full Text Available The title of this paper was derived from an incident I observed some years ago while accompanying a highly talented musician-songwriter friend to a performance. During a break, an audience member approached him to compliment the last song he had performed. He had written both the music and the lyrics to the song, one of many he had written. The audience member queried, “Is that a real song, or did you just make it up?” A touch amused, and not knowing whether he should be flattered or insulted, he politely replied, “It is a real song and I made it up.”This episode puts in mind a similar attitude in the social sciences that Glaser and Strauss (1967 noted, in which a small number of ’theoretical capitalists’ originate what are considered to be “real” theories and others are relegated to the role of “proletariat” testers. The means by which these theorists derived their theories remained largely mysterious. Unleashing proletariat testers was one of the chief rationales behind Glaser and Strauss’ development of grounded theory. It brought a democratic option into the social sciences that enabled anyone who learned the methodology to generate theory. The democratic ethos of the methodology may also have inadvertently unleashed an abundance of aspiring remodelers of the methodology, who unfortunately have eroded its primary purpose—to generate theories that are fully grounded in data rather than speculation or ideology.

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.

    To describe the process by which Chinese women accept living with breast cancer. Individual interviews were conducted with 18 Chinese women who completed breast cancer treatment. Data were collected from September 2014 to January 2015 at a large tertiary teaching hospital in Beijing, China. In this grounded theory study, data were analyzed using constant comparative and coding analysis methods. In order to explain the process of accepting having breast cancer among women in China through the grounded theory study, a model that includes 5 axial categories was developed. Cognitive reconstruction emerged as the core category. The extent to which the women with breast cancer accepted having the disease was found to increase with the treatment stage and as their treatment stage progressed with time. The accepting process included five stages: non-acceptance, passive acceptance, willingness to accept, behavioral acceptance, and transcendence of acceptance. Our study using grounded theory study develops a model describing the process by which women accept having breast cancer. The model provides some intervention opportunities at every point of the process. Copyright © 2017. Published by Elsevier Ltd.

    This study was conducted to identify factors that influenced milk-drinking behaviors of elementary school children in North Texas. Ten focus groups with a total of 41 children aged 6 to 11 years were conducted using a grounded theory approach. Based on the principles of Social Learning Theory, milk preferences and health beliefs were identified as personal factors that influenced drinking. Cafeteria rules, milk flavor, product packaging, modeling by adults, and shared experiences were environmental factors. The data suggest that school cafeterias can capitalize on their unique position to offer milk-drinking opportunities that children can share to combine nutrition education with sensory experience.

    To describe the challenges in combining two data sets during grounded theory analysis. The use of grounded theory in nursing research is common. It is a suitable method for studying human action and interaction. It is recommended that many alternative sources of data are collected to create as rich a dataset as possible. Data from interviews with people with diabetes (n=19) and their family members (n=19). Combining two data sets. When using grounded theory, there are numerous challenges in collecting and managing data, especially for the novice researcher. One challenge is to combine different data sets during the analysis. There are many methodological textbooks about grounded theory but there is little written in the literature about combining different data sets. Discussion is needed on the management of data and the challenges of grounded theory. This article provides a means for combining different data sets in the grounded theory analysis process.

    To explore three different approaches to grounded theory and consider some of the possible philosophical assumptions underpinning them. Grounded theory is a comprehensive yet complex methodology that offers a procedural structure that guides the researcher. However, divergent approaches to grounded theory present dilemmas for novice researchers seeking to choose a suitable research method. This is a methodology paper. This is a reflexive paper that explores some of the challenges experienced by a PhD student when choosing and operationalising a grounded theory approach. Before embarking on a study, novice grounded theory researchers should examine their research beliefs to assist them in selecting the most suitable approach. This requires an insight into the approaches' philosophical assumptions, such as those pertaining to ontology and epistemology. Researchers need to be clear about the philosophical assumptions underpinning their studies and the effects that different approaches will have on the research results. This paper presents a personal account of the journey of a novice grounded theory researcher who chose a grounded theory approach and worked within its theoretical parameters. Novice grounded theory researchers need to understand the different philosophical assumptions that influence the various grounded theory approaches, before choosing one particular approach.

    ABSTRACT Purpose: Adolescent girls are not sufficiently active to achieve health benefits. Social support from friends and family has been positively associated with physical activity in adolescent girls; however it is unclear how social support influences physical activity behaviour. This study aimed to develop a grounded theory of how social support influences physical activity in adolescent girls. Methods: A qualitative, constructivist grounded theory approach was adopted. Individual interviews explored adolescent girls’ perspectives of how significant others’ influenced their physical activity through providing social support, and through modelling physical activity. Results: Participants perceived social support to influence physical activity behaviour through performance improvements, self-efficacy, enjoyment, motivation and by enabling physical activity. Improvements in performance and self-efficacy were also linked to motivation to be active. Girls perceived modelling to influence behaviour through providing opportunities for them to be physically active, and by inspiring them to be active. Conclusion: The grounded theory outlines adolescent girls’ perceptions of how significant others influence their physical activity and provides a framework for future research examining the role of social support on physical activity.

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

    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

  18. Rethinking presence: a grounded theory of nurses and teleconsultation.

    2017-10-01

    To develop a theory that offered an evidence-based insight into the use of teleconsultation by nurses. Teleconsultation is the use of video to facilitate real-time, remote interaction between healthcare practitioners and patients. Although its popularity is growing, there is little understanding of how teleconsultation impacts on the role of nurses. The study adopted a constructivist grounded theory method, supplemented by the use of Straussian analytical approaches. Using selective and theoretical approaches, registered nurses with experience of using video in health care were sampled. Data were collected using semi-structured interviews exploring experiences, knowledge and feelings surrounding teleconsultation. Interviews were recorded, transcribed and subjected to three-stage, nonlinear manual analysis (open, axial and selective coding). Theoretical saturation occurred after 17 interviews. The core category identified from the data was 'nursing presence' Four subcategories of nursing presence were identified: operational, clinical, therapeutic and social. The degree to which presence could be achieved was dependent upon three influencing factors - enablers, constraints and compensation. Nurses provide different types of presence during teleconsultation, with the degree of presence dependent on specific characteristics of video-mediated communication. Where the use of video constrains the delivery of presence, nurses use a range of compensatory mechanisms to enhance patient care. Teleconsultation provides an innovative approach to enhancing the delivery of health care. This study provides nurses with insight into the impact of teleconsultation on their professional role, and an understanding of how best to use video-mediated communication to support patient care. © 2016 John Wiley & Sons Ltd.

    Reablement is an interprofessional, home-based rehabilitation service that aims to enable senior residents to cope with everyday life and to prevent functional impairments. Systematic accounts of what practitioners actually do when establishing reablement are lacking. This study aims to generate a grounded theory of practitioners' patterns of action when establishing reablement. The study is located in Norway, and grounded theory is the methodological approach. Data were collected from January 2014 to August 2016 through participant observations, focus group interviews and individual interviews. Informants are municipal healthcare employees in different organisational areas associated with the process of establishing reablement services (managers of conventional home care and representatives from the administration and service-provider offices). Altogether, 17 individuals are interviewed. The empirical data are analysed several times using open, selective and theoretical coding. The grounded theory, "tailoring reablement," includes three phases-replicating, adapting and establishing-and the strategies of collaborating, developing knowledge, habituating and filtering. The theory of tailoring reablement also includes the impact of the contextual factors. The study seeks to bridge the gap between research and practice. The theory of tailoring reablement emerges from an inductive approach and theorises participants' actions. The theory focuses on the phases from innovation to implementation. Establishing a new service model in a complex welfare setting requires a wide range of actors and agencies. Tailoring reablement also requires flexibility and professional autonomy. It is important to create terms and conditions for this within a stringent health and care service. The insights of this study have implications for practice development of reablement and can fit other public sector fields. © 2017 The Authors.

    National initiatives in the United States call for health research that addresses racial/ethnic disparities. Although grounded theory (GT) research has the potential to contribute much to the understanding of the health experiences of people of color, the extent to which it has contributed to health disparities research is unclear. In this article we describe a project in which we reviewed 44 GT studies published in Qualitative Health Research within the last five years. Using a framework proposed by Green, Creswell, Shope, and Clark (2007), we categorized the studies at one of four levels based on the status and significance afforded racial/ethnic diversity. Our results indicate that racial/ethnic diversity played a primary role in five studies, a complementary role in one study, a peripheral role in five studies, and an absent role in 33 studies. We suggest that GT research could contribute more to health disparities research if techniques were developed to better analyze the influence of race/ethnicity on health-related phenomena.

    Marriages are one of the most powerful predictors of health and longevity, yet research in stroke has focused separately on survivors' experience of impairments and how spouses deal with caregiving. The purpose of this constructivist grounded theory study was to understand the key themes related to reconstruction or breakdown of marriages after stroke. In semi-structured interviews, 18 couples in long-term marriages discussed how their marriages were reconstructed or broke down after one member of the couple returned home after being hospitalized for a stroke. Constant comparison methods were used to compare the experiences of 12 couples in which both partners indicated their relationship was going well with 6 couples who either separated or remained in parallel marriages. Analysis revealed an overarching process of reconstructing compatible role-identities and three themes related to the reconstruction or breakdown of the marital identity: feeling overwhelmed, resolving conflict, and perceiving value in the marriage. Our findings highlight that marriages are contexts in which survivors and spouses can recalibrate their role-identities. Marriage relationships are not peripheral to survivors' and spouses' outcomes after stroke; rather, marriage is fundamental to the management of impairments and to the well-being of the couple.

    Recovery is government mandated and a core facet of mental health reform. However, Recovery implementation in this country (Australia) has been inhibited by a lack of education of, and understanding from, clinicians. A grounded theory study was undertaken to explore the potential and existing role of lived experience practitioners in assisting meaningful implementations of Recovery within the Australian mental health sector. In-depth interviews were conducted with 13 people employed to work from a lived experience perspective. The findings suggest participants have experienced and observed significant barriers to the implementation of Recovery-focused practice while operating in lived experience roles. Three main issues emerged: (1) Recovery co-opted, (2) Recovery uptake, and (3) Recovery denial. For a genuine Recovery-focused mental health system to be developed, lived experience practitioners must be enabled to take their role as Recovery experts and leaders. Lived experience practitioners are the logical leaders of Recovery implementation due to their own internal experience and understandings of Recovery and the wider lived experience movement's development and championing of the concepts.

    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. © 2015 Wiley Publishing Asia Pty Ltd.

    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. Copyright © 2014 Elsevier Ltd. All rights reserved.

    2016-01-01

    This purpose of this study was to provide a theoretical account of how adolescents aged 13 to 18 years process the experience of having an ostomy. Qualitative study using grounded theory design. The sample comprised of 12 English-speaking adolescents aged 13-18 years: 10 with an ostomy and 2 with medical management of their disease. Respondents completed audio-recorded interviews that were transcribed verbatim. Data were analyzed using the constant comparative method until data saturation occurred. Dedoose, a Web-based qualitative methods management tool, was used to capture major themes arising from the data. Study results indicate that for adolescents between 13 and 18 years of age, processing the experience of having an ostomy includes concepts of the "physical self" and "social self" with the goal of "normalizing." Subcategories of physical self include (a) changing reality, (b) learning, and (c) adapting. Subcategories of social self include (a) reentering and (b) disclosing. This study sheds light on how adolescents process the experience of having an ostomy and how health care providers can assist adolescents to move through the process to get back to their desired "normal" state. Health care providers can facilitate the adolescent through the ostomy experience by being proactive in conversations not only about care issues but also about school and family concerns and spirituality. Further research is needed in understanding how parents process their adolescents' ostomy surgery experience and how spirituality assists adolescents in coping and adjustment with body-altering events.

    2004-11-01

    Full Text Available Moral distress is a pervasive problem in nursing, contributing to nurses’ emotional and physical health problems, loss of nurses’ ethical integrity,dissatisfaction with the work of nursing, and loss of nurses from the workforce. The purpose of this research was twofold: 1 to further elucidate the experiences and consequences of professional nurses’ moral distress and 2 to formulate a logical, systematic, and explanatory theory of moral distress and its consequences. METHOD: This Glaserian grounded theory study utilizedvolunteer and purposive sampling to recruit 21 registered nurses. Analysis of the data resulted in an original substantive theory of moral reckoning in nursing, which reaches further than the concept of moral distress, identifying a critical juncture in nurses’ lives and better explaining a process that affects nurses and the health care that they deliver. Results: Moral reckoning in nursing consists of a three-stage process. After a novice period, the nurse experiences a Stage of Ease in which there is comfort in the workplace and congruence of internal and external values. Unexpectedly, a situational bind occurs in which the nurse’s core beliefs come into irreconcilable conflict with social norms. This forces the nurse out of the Stage of Ease into the Stage of Resolution, in which the nurseeither gives up or makes a stand. The nurse then moves into the Stage of Reflection in which beliefs, values, and actions are iteratively examined. The nurse tries to make sense of experiences through remembering, telling the story, examining conflicts, and living with the consequences. Implications: In today’s complex health care system, nurses find themselves faced with morally troubling situations which if not resolved can lead to serious consequences for nurses, patients, and the health care system as a whole. This study sets the stage for further investigation on the human consequences of moral distress. Further, since moral

    2011-01-01

    The purpose of this paper is to develop a business model structure through coding 75 business model innovating cases by grounded theory approach which proposed by Strauss. The process of conducing this work goes through three stages. On stage of open coding, an iterative procedure is used to name, conceptualize and catagorize the varibles that describe business models in cases in order to formulate those catorigies, properities and dimensions that are related to business models. On stage of axial coding, according to their properities, those categories are distributed to six causal levels of paradigm model. On stage 3, the properties in each level are clustered into different components of business model. Eventually, a two-dimensional business modelstructure consisting of six levels and fifteen components has been established and its application has been illustrated through applying the structure to analyze the business model of a real company in detail. The results show that the business model structure not only improves the weakness of the existing model study on component detailing, construct comprehensiveness and model openness effectively, but also pertains to explanatory model and formal theory. Thus, the structure can be applied to business model description, assessment and the summarization of the model's innovation strategies across contexts. Specially, the structure can serve as a solid foundation to facilitate the probing of complicated issues relevant to business model, as well as a guideline for entrepreneur innovation and business model improvement.%以75个实际企业商业模式成功案例为样本,应用扎根理论的Strauss三阶段编码方法进行跨案例分析,构建商业模式结构模型.以迭代式开放性编码对案例中描述商业模式的变量进行概念化和类属化,依据主轴编码的典范模式将各类属按性质分布于具有因果关系的6个层次,将每个层次的类属性质聚类为具有三级结构的商

    A parametric cost model for ground-based telescopes is developed using multi-variable statistical analysis, The model includes both engineering and performance parameters. While diameter continues to be the dominant cost driver, other significant factors include primary mirror radius of curvature and diffraction limited wavelength. The model includes an explicit factor for primary mirror segmentation and/or duplication (i.e.. multi-telescope phased-array systems). Additionally, single variable models based on aperture diameter are derived. This analysis indicates that recent mirror technology advances have indeed reduced the historical telescope cost curve.

    Full Text Available This article seeks to answer the influence of the coloniality of knowledge, the cleansing of blood and the hybris of the zero ground in the conception of the theory and musical analysis which is taught in our Latin American universities. The aim is to examine the survival of coloniality in the imaginary of musical theory and analysis in order to recognize the predominant hegemonic discourses and propose some options to decolonize these disciplines of professional music education. The rationale is based on the presentation of some concepts of decolonial studies, research on the conservatory model and the ideology of theory and analysis.The article is divided into three parts. In the first one, an approximation is made to the concept of coloniality and its categories. The second takes the categories to review the ideology of the chosen fields of musical knowledge and the third proposes some options to decolonize our conceptions in higher education.

    A common goal of couples' therapy is to help individuals modify their view of each other and the relationship. Distorted views and appraisals contribute to conflict, and these can be manifest by use of rationalization or denial. This study explored appraisal distortion as an evaluative and moral process that occurs during partner conflict, particularly when it becomes contemptuous and aggressive. Using a philosophical base that is grounded in the ethical relationship, a model of appraisal distortion and couple conflict was created using constructivist grounded theory methods. The theoretical concepts derived from the data show relationships between one's relational stance, appraisal distortion, and verbal and physical aggression. This model implies that helping individuals take responsibility for appraisals is important in treating conflict.

    Shared decision-making (SDM) has the potential to overcome outdated social role models in the health care system. The concept, however, adheres to archaic epistemological assumptions as can be inferred from the rudimentary stage of the measurement methods used and from the information monopoly that the physician still holds in this concept. Advantages of an up-to-date model of knowledge for understanding and operationalising SDM are outlined. To this purpose, essential definitions of the concept are reflected in terms of epistemology. Accordingly, information emerges through a process of social construction. Likewise, interpersonal relations do not represent a static condition; rather, they develop anew with each interaction. Therefore, constructs suitable to focus on dyadic interaction processes can be used as indicators of sharing in SDM. Theories and methods of the interpersonal paradigm are advocated.

    Becoming an adolescent father is a significant and critical life event. Expectant fathers are faced with a concurrent dual developmental crisis: being an adolescent and becoming a father. This transition has a tremendous impact on these adolescents, their families and society. The impact on these individuals and society does not, at this point, seem to be clearly understood. To explore the process of Thai adolescents becoming first-time fathers with an unplanned pregnancy during their girlfriend's pregnancy. A grounded theory approach was used, drawing upon semi-structured interviews with 16 expectant fathers in Chiang Mai, Thailand. 'Growing into teen fatherhood' was the basic social process that emerged as the core category. These fathers used this process for developing themselves to fatherhood. This process was further divided into three phases: enduring the conflict of future role, accepting impending fatherhood and developing a sense of being teen expectant father. Throughout this process, the participants encountered many conflicts and challenges. They employed various strategies to manage the emotional, financial and interpersonal challenges they faced during the transition to fatherhood. This study provides data as well as anecdotal evidence for healthcare professionals to better understand adolescent fathers and their unique challenges during their girlfriend's pregnancy. A better understanding of these rich findings will enable healthcare professionals to assist young men and boys in their struggle to transition to fatherhood. Our data may guide policymakers in developing support groups, effective mentoring programs and national follow-up services as standard services in hospitals' care for first-time adolescent fathers in Thailand. © 2017 International Council of Nurses.

  18. Grounded Theory and Pragmatism: The Curious Case of Anselm Strauss

    Full Text Available Sir Arthur CONAN DOYLE's stories featuring Sherlock Holmes are justly famous the world over. In The Memoirs of Sherlock Holmes (1993 one story entitled Silver Blaze contains an exchange between Holmes and a Scotland Yard detective as follows: Gregory (Scotland Yard detective: "Is there any other point to which you would wish to draw my attention?" Holmes: "To the curious incident of the dog in the night-time." Gregory: "The dog did nothing in the night-time." Holmes: "That was the curious incident." In similar fashion I wish to draw attention to the curious case of Anselm STRAUSS: There is already a good deal of work pointing to the continuities between the Grounded Theory Method (GTM and the Pragmatism of John DEWEY and Charles PEIRCE. This has usually focused on Anselm STRAUSS with his Chicago-influenced Pragmatist background, although STRAUSS himself never articulated the way in which Pragmatism informed or could be brought to bear on the method as it evolved from the 1960s onwards. This paper argues that many of the contentious issues surrounding GTM can be resolved if they are understood against the context of some of the core tenets of Pragmatism, particularly the ways in which some of the more recent Pragmatists such as Richard RORTY have brought them back as a focus of attention. In so doing is raises the question of why, given his intellectual background and formation, Anselm STRAUSS did so little to bring Pragmatist ideas into GTM in its later embodiments and extended statements. That is the "curious incident" to which specific attention is drawn at several points in what follows; it remains a perplexing one, with perhaps no convincing solution, unlike the Sherlock Holmes mystery alluded to above.

    2017-12-01

    To conduct an empirical investigation using qualitative techniques of the way dentists engage in the process of reading a technique-oriented journal article and what they pay attention to in the process. Grounded theory was used to identify how dentists read an article describing the fabrication of an interim prosthesis in the esthetic zone. Twenty-one experienced practitioners were videotaped, and their verbatim reflections were coded. The sequence of attending to various features of the paper was noted. Ninety-five percent of readers voiced specific, multiple attempts to identify or refine the main purpose of the article as they processed the material. All readers engaged in various activities to navigate through the article, including skipping and backtracking, and none "read" the article straight through. All readers also made repeated observations about the relevance of the technique to their personal practice situation. Eighty percent used some form of "distancing," whereby the content and value of the article were accepted, but the reader reserved the privilege of not being bound by the results because of technical, sponsorship, or methodological issues that "might be present." The quality of photographs was accepted as a proxy for the quality of technical work performed. Dentists actively customized the reading of a journal article that described a technical procedure. They imposed a non-linear structure for absorbing information and a standard of personal relevance, and, while accepting the results, created reasons for not necessarily having to accept them as applicable. The approach clinicians use in reading a procedural article may be different from the structure writers use in preparing a paper. © 2016 by the American College of Prosthodontists.

    Full Text Available Kathy CHARMAZ is one of the most important thinkers in grounded theory methodology today. Her trailblazing work on constructivist grounded theory continues to inspire research across many disciplines and around the world. In this interview, she reflects on the aura surrounding qualitative inquiry that existed in California in the late 1960s to early 1970s and the lessons she learned from her first forays into empirical research. She comments on the trajectory that grounded theory research has followed since then and gives an account of her own perspective on constructivist grounded theory. In doing so, she underlines the importance of the Chicago School and symbolic interactionist tradition for grounded theory research work today and shows where the latter is positioned in the current field of qualitative fieldwork.

    2006-01-01

    Although it is generally acknowledged that symbolic interactionism and grounded theory are connected, the precise nature of their connection remains implicit and unexplained. As a result, many grounded theory studies are undertaken without an explanatory framework. This in turn results in the description rather than the explanation of data determined. In this report, the authors make explicit and explain the nature of the connections between symbolic interactionism and grounded theory research. Specifically, they make explicit the connection between Blumer's methodological principles and processes and grounded theory methodology. In addition, the authors illustrate the explanatory power of symbolic interactionism in grounded theory using data from a study of the HIV/AIDS experiences of married and widowed Thai women.

    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. 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. 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. This is the first grounded theory study to explore VP design. This original research has produced a model which enhances understanding of how and why the delivery and design of VPs

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

    Science.gov (United States)

    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.

    Considering the paucity of studies dealing with the holistic aspect of the cancer experience, this grounded theory study seeks to conceptualize the process of cancer survivorship among Filipinos. Twenty-seven Filipino cancer survivors were purposively selected, and a two-part instrument, specifically robotfoto and focus group interviews, was used to gather data. The Glaserian method of grounded theory analysis was used, and extended texts were analyzed inductively via a dendrogram. Member checking and correspondence were observed to validate the surfacing stages, leading to the conceptualization of a theoretical model termed as the Ribbon of Cancer Survivorship. The said model describes the trifling (living before), transfusing (accepting the reality), transforming (being strong), and transcending (living beyond) phases of cancer survivorship. Ten interesting substages were also identified, namely: tainting, desolating, disrupting, and embracing for the transfusing phase; tormenting, distressing, awakening, and transfiguring for the transforming phase, and trembling and enlivening for the transcending phase. The resulting theoretical model has clearly and successfully described the entire process of cancer survivorship among Filipinos. It is hoped that the model be used as a reference for future studies about cancer survivorship and as a guide for nurses in providing a more empathetic care among cancer patients.

    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.

    Warped models, originating with the ideas of Randall and Sundrum, provide a fascinating extension of the standard model with interesting consequences for the LHC. We investigate in detail how string theory realises such models, with emphasis on fermion localisation and the computation of Yukawa couplings. We find, in contrast to the 5d models, that fermions can be localised anywhere in the extra dimension, and that there are new mechanisms to generate exponential hierarchies amongst the Yukawa couplings. We also suggest a way to distinguish these string theory models with data from the LHC. (author)

  13. Method development at Nordic School of Public Health NHV: Phenomenology and Grounded Theory.

    Strandmark, Margaretha

    2015-08-01

    Qualitative methods such as phenomenology and grounded theory have been valuable tools in studying public health problems. A description and comparison of these methods. Phenomenology emphasises an inside perspective in form of consciousness and subjectively lived experiences, whereas grounded theory emanates from the idea that interactions between people create new insights and knowledge. Fundamental aspects of phenomenology include life world, consciousness, phenomenological reduction and essence. Significant elements in grounded theory are coding, categories and core categories, which develop a theory. There are differences in the philosophical approach, the name of the concept and the systematic tools between the methods. Thus, the phenomenological method is appropriate when studying emotional and existential research problems, and grounded theory is a method more suited to investigate processes. © 2015 the Nordic Societies of Public Health.

    1998-01-01

    The ground state of randomly charged polyampholytes (polymers with positive and negatively charged groups along their backbone) is conjectured to have a structure similar to a necklace, made of weakly charged parts of the chain, compacting into globules, connected by highly charged stretched 'strings' attempted to quantify the qualitative necklace model, by suggesting a zero approximation model, in which the longest neutral segment of the polyampholyte forms a globule, while the remaining part will form a tail. Expanding this approximation, we suggest a specific necklace-type structure for the ground state of randomly charged polyampholyte's, where all the neutral parts of the chain compact into globules: The longest neutral segment compacts into a globule; in the remaining part of the chain, the longest neutral segment (the second longest neutral segment) compacts into a globule, then the third, and so on. A random sequence of charges is equivalent to a random walk, and a neutral segment is equivalent to a loop inside the random walk. We use analytical and Monte Carlo methods to investigate the size distribution of loops in a one-dimensional random walk. We show that the length of the nth longest neutral segment in a sequence of N monomers (or equivalently, the nth longest loop in a random walk of N steps) is proportional to N/n 2 , while the mean number of neutral segments increases as √N. The polyampholytes in the ground state within our model is found to have an average linear size proportional to dN, and an average surface area proportional to N 2/3

    Researchers are increasingly using grounded theory methodologies to study the professional experience of nurses and midwives. To review common grounded theory characteristics and research design quality as described in grounded theory studies of coping strategies used by nurses and midwives. A systematic database search for 2005-2015 identified and assessed grounded theory characteristics from 16 studies. Study quality was assessed using a modified Critical Appraisal Skills Programme tool. Grounded theory was considered a methodology or a set of methods, able to be used within different nursing and midwifery contexts. Specific research requirements determined the common grounded theory characteristics used in different studies. Most researchers did not clarify their epistemological and theoretical perspectives. To improve research design and trustworthiness of grounded theory studies in nursing and midwifery, researchers need to state their theoretical stance and clearly articulate their use of grounded theory methodology and characteristics in research reporting.

    2014-03-01

    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.

    2017-07-20

    Policies internationally endorse the recovery paradigm as the appropriate foundation for youth mental health services. However, given that this paradigm is grounded in the views of adults with severe mental illness, applicability to youth services and relevance to young people is uncertain, particularly as little is known about young people's views. A comprehensive understanding of the experiences and expectations of young people is critical to developing youth mental health services that are acceptable, accessible, effective and relevant. To inform development of policy and youth services, the study described in this protocol aims to develop a comprehensive account of the experiences and expectations of 12-17 year olds as they encounter mental disorders and transition through specialist mental health services. Data will be analysed to model recovery from the adolescents' perspective. This grounded theory study will use quantitative and qualitative data collected in interviews with 12-17 year olds engaged with specialist Child/Youth Mental Health Service in Queensland, Australia. Interviews will explore adolescents' expectations and experiences of mental disorder, and of services, as they transition through specialist mental health services, including the meaning of their experiences and ideas of 'recovery' and how their experiences and expectations are shaped. Data collection and analysis will use grounded theory methods. Adolescents' experiences will be presented as a mid-range theory. The research will provide tangible recommendations for youth-focused mental health policy and practice. Findings will be disseminated within academic literature and beyond to participants, health professionals, mental health advocacy groups and policy and decision makers via publications, research summaries, conferences and workshops targeting different audiences. Ethical and research governance approvals have been obtained from relevant Human Research Ethics committees and all

    As adults age with human immunodeficiency virus (HIV), the role for rehabilitation continues to emerge. Understanding how social participation is affected among women aging with HIV can inform occupational therapy assessment and treatment. Our purpose was to develop a theoretical model that describes the experiences of social participation from the perspective of older women living with HIV. A grounded theory methodological approach was utilized. We conducted interviews with 20 women living with HIV, age 50 or older, to explore various aspects of social participation, including self-care, relationships with others, and access to health and social services. Emergent themes informed the theoretical model. The theoretical model comprises four concepts related to social participation: social engagement, social isolation, contrasting perceptions about factors variably influencing participation, and contextual influences that may enhance or hinder social participation. Women aging with HIV experience social participation as a dynamic process involving social engagement and isolation. Contextual influences may promote and impede social participation.

  6. Relational grounding facilitates development of scientifically useful multiscale models

    Directory of Open Access Journals (Sweden)

    Lam Tai

    2011-09-01

    Full Text Available Abstract We review grounding issues that influence the scientific usefulness of any biomedical multiscale model (MSM. Groundings are the collection of units, dimensions, and/or objects to which a variable or model constituent refers. To date, models that primarily use continuous mathematics rely heavily on absolute grounding, whereas those that primarily use discrete software paradigms (e.g., object-oriented, agent-based, actor typically employ relational grounding. We review grounding issues and identify strategies to address them. We maintain that grounding issues should be addressed at the start of any MSM project and should be reevaluated throughout the model development process. We make the following points. Grounding decisions influence model flexibility, adaptability, and thus reusability. Grounding choices should be influenced by measures, uncertainty, system information, and the nature of available validation data. Absolute grounding complicates the process of combining models to form larger models unless all are grounded absolutely. Relational grounding facilitates referent knowledge embodiment within computational mechanisms but requires separate model-to-referent mappings. Absolute grounding can simplify integration by forcing common units and, hence, a common integration target, but context change may require model reengineering. Relational grounding enables synthesis of large, composite (multi-module models that can be robust to context changes. Because biological components have varying degrees of autonomy, corresponding components in MSMs need to do the same. Relational grounding facilitates achieving such autonomy. Biomimetic analogues designed to facilitate translational research and development must have long lifecycles. Exploring mechanisms of normal-to-disease transition requires model components that are grounded relationally. Multi-paradigm modeling requires both hyperspatial and relational grounding.

  8. Kleinian singularities and the ground ring of c=1 string theory

    International Nuclear Information System (INIS)

    Ghoshal, D.; Jatkar, D.P.; Mukhi, S.

    1993-01-01

    We investigate the nature of the ground ring of c=1 string theory at the special ADE points in the c=1 moduli space associated to discrete subgroups of SU(2). The chiral ground rings at these points are shown to define the ADE series of singular varieties introduced by Klein. The non-chiral ground rings relevant to closed-string theory are 3 real dimensional singular varieties obtained as U(1) quotients of the kleinian varieties. The unbroken symmetries of the theory at these points are the volume-preserving diffeomorphisms of these varieties. The theory of kleinian singularities has a close relation to that of complex hyperKaehler surfaces, or gravitational instantons. We speculate on the relevance of these instantons and of self-dual gravity in c=1 string theory. (orig.)

  10. Ground states of a spin-boson model

    International Nuclear Information System (INIS)

    Amann, A.

    1991-01-01

    Phase transition with respect to ground states of a spin-boson Hamiltonian are investigated. The spin-boson model under discussion consists of one spin and infinitely many bosons with a dipole-type coupling. It is shown that the order parameter of the model vanishes with respect to arbitrary ground states if it vanishes with respect to ground states obtained as (biased) temperature to zero limits of thermic equilibrium states. The ground states of the latter special type have been investigated by H. Spohn. Spohn's respective phase diagrams are therefore valid for arbitrary ground states. Furthermore, disjointness of ground states in the broken symmetry regime is examined

  11. The Relationship between an Emerging Grounded Theory and the Existing Literature: Four phases for consideration

    Directory of Open Access Journals (Sweden)

    Vivian B. Martin, Ph.D.

    2006-06-01

    Full Text Available The relationship between grounded theory researchers and the existing literature has become a red herring that even confuses some grounded theorists who have completed a study. Antoinette McCallin’s essay does a commendable job outlining the realities of the research terrain that make proceeding without some exposure to the literature unlikely and ill-advised in most situations. When embarking on my dissertation, I needed to know enough about the literature, both substantive and methodological, to argue for the use of classic grounded theory as opposed to many other choices within my field; yet my study benefited from the necessary tensions between the emerging grounded theory and the existing literature. In this brief essay I propose that the relationship between the existing literature and a developing grounded theory project goes through four discernible phases:noncommittal, comparative, integrative, and, if the analyst can push, a transcendent phase in which the theory is not simply one of a number of theories of a kind within the discipline’s literature. I explain the phases to make more explicit the under-recognized subversive potential of grounded theory to push pass disciplinary boundaries by broadening the ‘relevant’ literature. Barney Glaser has often admonished grounded theory researchers to put off the literature to avoid wasting time and energy with literature that may prove irrelevant. I have not found such literature to be irrelevant as much as limited, and in some cases restricted by what a particular discipline defines as the appropriate literature. Therefore, the question of what literature offers possibilities for literature review and comparisons that would allow for richer knowledge generation. I return to this matter toward the end of the essay.

  12. A Grounded Theory of Sexual Minority Women and Transgender Individuals' Social Justice Activism.

    Science.gov (United States)

    Hagen, Whitney B; Hoover, Stephanie M; Morrow, Susan L

    2018-01-01

    Psychosocial benefits of activism include increased empowerment, social connectedness, and resilience. Yet sexual minority women (SMW) and transgender individuals with multiple oppressed statuses and identities are especially prone to oppression-based experiences, even within minority activist communities. This study sought to develop an empirical model to explain the diverse meanings of social justice activism situated in SMW and transgender individuals' social identities, values, and experiences of oppression and privilege. Using a grounded theory design, 20 SMW and transgender individuals participated in initial, follow-up, and feedback interviews. The most frequent demographic identities were queer or bisexual, White, middle-class women with advanced degrees. The results indicated that social justice activism was intensely relational, replete with multiple benefits, yet rife with experiences of oppression from within and outside of activist communities. The empirically derived model shows the complexity of SMW and transgender individuals' experiences, meanings, and benefits of social justice activism.

  5. Kohn-Sham Theory for Ground-State Ensembles

    International Nuclear Information System (INIS)

    Ullrich, C. A.; Kohn, W.

    2001-01-01

    An electron density distribution n(r) which can be represented by that of a single-determinant ground state of noninteracting electrons in an external potential v(r) is called pure-state v -representable (P-VR). Most physical electronic systems are P-VR. Systems which require a weighted sum of several such determinants to represent their density are called ensemble v -representable (E-VR). This paper develops formal Kohn-Sham equations for E-VR physical systems, using the appropriate coupling constant integration. It also derives local density- and generalized gradient approximations, and conditions and corrections specific to ensembles

  6. Perceived changes associated with autogenic training for anxiety: a grounded theory study.

    Science.gov (United States)

    Yurdakul, Levent; Holttum, Sue; Bowden, Ann

    2009-12-01

    Autogenic training (AT) is a behaviourally orientated intervention usually taught in eight or nine sessions in the United Kingdom: clients are taught six simple mental formulae designed to induce a calm state of mind and body, five additional emotional expression exercises, and individually tailored 'personal formulae' for supporting positive change. In the absence of existing psychological (as opposed to neuro-physiological) models of AT's mechanisms, this study aimed to produce the first such model, drawing on the perceptions of recent AT clients. An abbreviated form of grounded theory was used to explore retrospectively and in detail the experiences of a small sample of people of the process of change. Forty people were approached and 12 women participated who had completed AT in group form after referral for anxiety. Each was interviewed individually. A preliminary model of change was produced, grounded in the interview data. Factors reported to be salient were learning in a group, the core AT experience (the six standard exercises), difficulties with practice, the importance of regular practice integrated into daily life, and enhanced well-being and coping, which incorporated reduced worrying and clearer thinking. Limitations of the study are discussed, as are areas for further research and implications for anxiety treatment. This was a small study with a self-selected sample. However, theoretical generalizations can be made about the process of change. Since AT does not specifically focus on challenging negative cognitions, the cognitive changes reported have implications for anxiety treatments.

  7. Morbidity and Mortality Conference: Its Purpose Reclaimed and Grounded in Theory.

    Science.gov (United States)

    Gregor, Alexander; Taylor, David

    2016-01-01

    The morbidity and mortality conference (MMC) remains a central activity within the departments of our academic healthcare institutions. It is deeply rooted in the premise that we can learn from our mistakes, thereby improving the care we provide. Recent advances in our understanding of medical error and quality improvement have challenged the value of traditional models of MMC. As a result the purpose of MMC has become clouded and ill-defined: Is it an educational conference that promotes mastery of clinical acumen, or is it a venue to drive quality improvement by addressing systems-based issues in delivering care? Or can it serve both purposes? Review of the history of MMC, the literature, and critical application of education theory demonstrates the source of the confusion and the challenges in viewing it through the exclusive lens of either education or quality improvement. Application of experiential learning theory helps resolve this discord showing how the conference facilitates the development of clinical mastery while informing quality improvement programs about important and relevant systems-based issues. Building on this, we present a model for MMC involving five essential elements: case-based involving an adverse patient event, anonymity for participants, expert guided critical analysis, reframing understanding of the case presentation and related systems-based factors, and projection to practice change. This model builds on previously described models, is grounded in the literature, and helps clarify its role from both the educational and the quality improvement perspectives.

  8. Using extant literature in a grounded theory study: a personal account.

    2015-03-01

    To provide a personal account of the factors in a doctoral study that led to the adoption of classic grounded theory principles relating to the use of literature. Novice researchers considering grounded theory methodology will become aware of the contentious issue of how and when extant literature should be incorporated into a study. The three main grounded theory approaches are classic, Straussian and constructivist, and the seminal texts provide conflicting beliefs surrounding the use of literature. A classic approach avoids a pre-study literature review to minimise preconceptions and emphasises the constant comparison method, while the Straussian and constructivist approaches focus more on the beneficial aspects of an initial literature review and researcher reflexivity. The debate also extends into the wider academic community, where no consensus exists. This is a methodological paper detailing the authors' engagement in the debate surrounding the role of the literature in a grounded theory study. In the authors' experience, researchers can best understand the use of literature in grounded theory through immersion in the seminal texts, engaging with wider academic literature, and examining their preconceptions of the substantive area. The authors concluded that classic grounded theory principles were appropriate in the context of their doctoral study. Novice researchers will have their own sets of circumstances when preparing their studies and should become aware of the different perspectives to make decisions that they can ultimately justify. This paper can be used by other novice researchers as an example of the decision-making process that led to delaying a pre-study literature review and identifies the resources used to write a research proposal when using a classic grounded theory approach.

  9. Theories of the nuclear ground state beyond Hartree-Fock

    International Nuclear Information System (INIS)

    Gogny, D.

    1979-01-01

    Intensive efforts have been invested toward defining a microscopic approach, simple enough to render feasible systematic calculations of nuclear structure and of the some time sufficiently rich in information as to serve for updating traditional microscopic approaches to the collective excitations. Our starting point is the mean field approximation with density dependent effective forces. To describe the collective excitations we use the two well known extensions based on the H.F. theory namely the random phase approximation and the adiabatic approximation to the time dependent Hartree-Fock theory. The purpose of this paper is to show what sort of calculations can be effectively carried out in the frame of such fully self consistent approaches. (KBE) 891 KBE/KBE 892 ARA

    2005-01-01

    We study the Robertson-Walker minisuperspace model in histories theory, motivated by the results that emerged from the histories approach to general relativity. We examine, in particular, the issue of time reparametrization in such systems. The model is quantized using an adaptation of reduced state space quantization. We finally discuss the classical limit, the implementation of initial cosmological conditions and estimation of probabilities in the histories context

  12. A Mixed Prediction Model of Ground Subsidence for Civil Infrastructures on Soft Ground

    Directory of Open Access Journals (Sweden)

    Kiyoshi Kobayashi

    2012-01-01

    Full Text Available The estimation of ground subsidence processes is an important subject for the asset management of civil infrastructures on soft ground, such as airport facilities. In the planning and design stage, there exist many uncertainties in geotechnical conditions, and it is impossible to estimate the ground subsidence process by deterministic methods. In this paper, the sets of sample paths designating ground subsidence processes are generated by use of a one-dimensional consolidation model incorporating inhomogeneous ground subsidence. Given the sample paths, the mixed subsidence model is presented to describe the probabilistic structure behind the sample paths. The mixed model can be updated by the Bayesian methods based upon the newly obtained monitoring data. Concretely speaking, in order to estimate the updating models, Markov Chain Monte Calro method, which is the frontier technique in Bayesian statistics, is applied. Through a case study, this paper discussed the applicability of the proposed method and illustrated its possible application and future works.

  13. Grounded Theory Study of Conflicts in Norwegian Agile Software Projects: The Project Managers’ Perspective

    2016-07-01

    Full Text Available This paper aims to explore the process of conflicts in agile software projects. The purpose was to investigate the causes and consequences of these conflicts. For this purpose, we conducted a qualitative study involving agile software projects in Norway. Grounded theory was used to analyze the data and the interview findings are presented using Glaser´s Six C model (context, condition, causes, consequences, contingencies, and covariance. The research findings suggest that there are several causes of conflicts. These include: the role of the product owner, an inexperienced project manager, the customer’s lack of knowledge about methodology organizational hierarchy in public companies, contracting, personal egos, financial issues, not getting the right team. Consequences of conflicts include: decreased productivity, wastage of time and resources, diverted attention from project objectives loss of motivation, poor decision making, loss of communication. Based on interview data, different conflict strategies are suggested and these include appropriately skilled project manager, communication and negotiation, defining clear roles, stakeholder analysis, managing stakeholder´s expectations, discussion, finding the root cause of conflict. Project managers are using these strategies to avoid or resolve conflicts. The competencies required to handle these kind of conflicts are also discussed in the paper, while the implications of theory and practice of conflict management theory are also presented.

  14. The process of patient enablement in general practice nurse consultations: a grounded theory study.

    2017-05-01

    The aim of this study was to gain insight into the process of patient enablement in general practice nursing consultations. Enhanced roles for general practice nurses may benefit patients through a range of mechanisms, one of which may be increasing patient enablement. In studies with general practitioners enhanced patient enablement has been associated with increases in self-efficacy and skill development. This study used a constructivist grounded theory design. In-depth interviews were conducted with 16 general practice nurses and 23 patients from 21 general practices between September 2013 - March 2014. Data generation and analysis were conducted concurrently using constant comparative analysis and theoretical sampling focussing on the process and outcomes of patient enablement. Use of the storyline technique supported theoretical coding and integration of the data into a theoretical model. A clearly defined social process that fostered and optimised patient enablement was constructed. The theory of 'developing enabling healthcare partnerships between nurses and patients in general practice' incorporates three stages: triggering enabling healthcare partnerships, tailoring care and the manifestation of patient enablement. Patient enablement was evidenced through: 1. Patients' understanding of their unique healthcare requirements informing their health seeking behaviours and choices; 2. Patients taking an increased lead in their partnership with a nurse and seeking choices in their care and 3. Patients getting health care that reflected their needs, preferences and goals. This theoretical model is in line with a patient-centred model of health care and is particularly suited to patients with chronic disease. © 2016 John Wiley & Sons Ltd.

    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.

    2016-05-01

    Full Text Available 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.

    2018-06-01

    Interpersonal trust between patient and nurse is important in patient-centered care. Trust development may be more difficult if the patient and nurse do not speak the same language. In this grounded theory study, Spanish-speaking Mexican American adults ( n = 20) hospitalized on a medical-surgical or obstetric unit in the Midwestern United States were interviewed. Through data analysis, a model of how trust develops between nurse and patient revealed eight categories and the core category Caring for Me Well Even When Not Understanding Me. The beginning phase had four categories: Asking for Help, Bothering, Communicating, and Understanding. The middle phase had two categories: Platicando (chatting) and Being Available. The end point category was Having Trust, and outcomes were Feeling Comfortable and Feeling Supported. The language barrier was a hindrance to trust development but the nurse's way of being (personality) was more important. Therefore, the patient did develop trust with nurses who did not speak Spanish.

    2016-05-01

    To explore nursing care actions that lead to culturally competent care for Hispanic patients. Nurses report apprehension when delivering nursing care because of language barriers and a lack of Hispanic cultural understanding. Research is needed to inform culturally aware nursing practice actions for Hispanic patients. The study used a qualitative, grounded theory design to address the questions: (a) What cultural knowledge should nurses have when caring for Hispanic patients and families and (b) What nursing actions should nurses take to provide culturally competent care? Hispanic lay health promoters and Hispanic community members were interviewed to make recommendations for care. A model was identified that informs culturally competent nursing care. "Connectedness," the central phenomenon, describes nursing actions and contains subthemes explaining influences on nursing care. "Up to You" and "At the Mercy of the System" are descriptive themes influencing connectedness. Connectedness is central to culturally well-informed nurse-patient interactions. © The Author(s) 2014.

    2014-02-01

    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.

    Lambe, Catherine I; Hoare, Karen J

    2016-01-01

    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. © 2015 John Wiley & Sons Ltd.

  4. Linking the Intercultural and Grounded Theory: Methodological Issues in Migration Research

    2009-01-01

    Full Text Available Connecting intercultural research with Grounded Theory was advocated in the early history of intercultural theorising and includes the development of researchers' intercultural competencies. Such competency comes to the fore where intercultural theory places an equal emphasis on home and host cultures in migration research. In this context we have found a Grounded Theory approach particularly suitable for disentangling complex interlinkings within migration experiences and their individual outcomes. Grounded Theory allows for the exploration of various theories in different fields and the emergence of new or deeper interpretations of intercultural experiences, including where research has not engaged deeply with or avoided intercultural contexts. The use of software, based on Grounded Theory, provides the resource for systematically exploring the inter-related nature of data. In addition, engaging in intercultural research, in particular, raises questions around our practice as social science researchers: adherence to ethics guidelines, for instance, can be in some conflict with the relations we build with members of communities whose cultural values, for instance around friendship or trust, impact on the norms of both our own and institutional expectations. This leads to reflection on the relationship with research participants in terms of our own intercultural experiences and position. URN: urn:nbn:de:0114-fqs0901363

    Great variety exists in the roles that family medicine residency faculty fill in the lives of their residents. A family medicine-specific model has never been created to describe and promote effective training relationships. This research aims to create a consensus model for faculty development, ethics education, and policy creation. Using a modified grounded theory methods, researchers conducted phone interviews with 22 key informants from US family medicine residencies. Data were analyzed to delineate faculty roles, common role conflicts, and ethical principles for avoiding and managing role conflicts. Key informants were asked to apply their experience and preferences to adapt an existing model to fit with family medicine residency settings. The primary result of this research is the creation of a family medicine-specific model that describes faculty roles and provides insight into how to manage role conflicts with residents. Primary faculty roles include Role Model, Advisor, Teacher, Supervisor, and Evaluator. Secondary faculty roles include Friendly Colleague, Wellness Supporter, and Helping Hand. The secondary roles exist on a continuum from disengaged to enmeshed. When not balanced, the secondary roles can detract from the primary roles. Differences were found between role expectations of physician versus behavioral science faculty and larger/university/urban residencies versus smaller/community/rural residencies. Diversity of opinion exists related to the types of roles that are appropriate for family medicine faculty to maintain with residents. This new model is a first attempt to build consensus in the field and has application to faculty development, ethics education, and policy creation.

  8. "Emergence" vs. "Forcing" of Empirical Data? A Crucial Problem of "Grounded Theory" Reconsidered

    Directory of Open Access Journals (Sweden)

    Udo Kelle

    2005-05-01

    Full Text Available Since the late 1960s Barney GLASER and Anselm STRAUSS, developers of the methodology of "Grounded Theory" have made several attempts to explicate, clarify and reconceptualise some of the basic tenets of their methodological approach. Diverging concepts and understandings of Grounded Theory have arisen from these attempts which have led to a split between its founders. Much of the explication and reworking of Grounded Theory surrounds the relation between data and theory and the role of previous theoretical assumptions. The book which initially established the popularity of GLASER's and STRAUSS' methodological ideas, "The Discovery of Grounded Theory", contains two conflicting understandings of the relation between data and theory—the concept of "emergence" on the one hand and the concept of "theoretical sensitivity" on the other hand. Much of the later developments of Grounded Theory can be seen as attempts to reconcile these prima facie diverging concepts. Thereby GLASER recommends to draw on a variety of "coding families" while STRAUSS proposes the use of a general theory of action to build an axis for an emerging theory. This paper first summarises the most important developments within "Grounded Theory" concerning the understanding of the relation between empirical data and theoretical statements. Thereby special emphasis will be laid on differences between GLASER's and STRAUSS' concepts and on GLASER's current critique that the concepts of "coding paradigm" and "axial coding" described by STRAUSS and Juliet CORBIN lead to the "forcing" of data. It will be argued that GLASER's critique points out some existing weaknesses of STRAUSS' concepts but vastly exaggerates the risks of the STRAUSSian approach. A main argument of this paper is that basic problems of empirically grounded theory construction can be treated much more effectively if one draws on certain results of contemporary philosophical and epistemological discussions and on widely

  11. Understanding psychological distress among mothers in rural Nepal: a qualitative grounded theory exploration

    Science.gov (United States)

    2014-01-01

    Background There is a large burden of psychological distress in low and middle-income countries, and culturally relevant interventions must be developed to address it. This requires an understanding of how distress is experienced. We conducted a qualitative grounded theory study to understand how mothers experience and manage distress in Dhanusha, a low-resource setting in rural Nepal. We also explored how distressed mothers interact with their families and the wider community. Methods Participants were identified during a cluster-randomised controlled trial in which mothers were screened for psychological distress using the 12-item General Health Questionnaire (GHQ-12). We conducted 22 semi-structured interviews with distressed mothers (GHQ-12 score ≥5) and one with a traditional healer (dhami), as well as 12 focus group discussions with community members. Data were analysed using grounded theory methods and a model was developed to explain psychological distress in this setting. Results We found that distress was termed tension by participants and mainly described in terms of physical symptoms. Key perceived causes of distress were poor health, lack of sons, and fertility problems. Tension developed in a context of limited autonomy for women and perceived duty towards the family. Distressed mothers discussed several strategies to alleviate tension, including seeking treatment for perceived physical health problems and tension from doctors or dhamis, having repeated pregnancies until a son was delivered, manipulating social circumstances in the household, and deciding to accept their fate. Their ability to implement these strategies depended on whether they were able to negotiate with their in-laws or husbands for resources. Conclusions Vulnerability, as a consequence of gender and social disadvantage, manifests as psychological distress among mothers in Dhanusha. Screening tools incorporating physical symptoms of tension should be envisaged, along with

    2015-09-01

    To develop a preliminary model of the experiences of people undergoing combined treatment with antidepressant medication and cognitive-behavioural therapy (CBT) for depression. The study used a qualitative methodology informed by grounded theory. Participants were 12 adults who had received treatment with antidepressant medication and CBT for depression. Participants engaged in a semistructured interview about their experiences. Interviews were transcribed and analysed using components of grounded theory methodology. Medication was often seen as an initial aid to surviving a crisis. Staying on medication longer term resulted in some participants feeling caught in a 'drug loop'. Feeling that medication was unhelpful or actively harmful could contribute to participants seeking CBT. Medics also offered information on CBT and acted as gatekeepers, meaning that negotiation was sometimes necessary. CBT was described as a process of being guided towards skilled self-management. Occasionally, participants felt that medication had facilitated CBT at one or more stages. Conversely, developing skilled self-management through CBT could reduce feelings of dependency on medication and affect several of the other elements maintaining the 'drug loop'. Antidepressant medication and CBT are perceived and experienced differently, with CBT often being seen as an alternative to medication, or even as a means to discontinue medication. Service users' experiences and beliefs about medication may thus affect their engagement and goals in CBT, and it may be important for therapists to consider this. Practitioners who prescribe medication should ensure that they also provide information on the availability and appropriateness of CBT, and engage in an open dialogue about treatment options. CBT practitioners should explore aspects of clients' experiences and beliefs about medication. This would particularly include clients' experiences of the effects of medication, their beliefs about

    This paper presents a discussion of the differences in using participant observation as a data collection method by comparing the classic grounded theory methodology of Barney Glaser with the constructivist grounded theory methodology by Kathy Charmaz. Participant observations allow nursing researchers to experience activities and interactions directly in situ. However, using participant observations as a data collection method can be done in many ways, depending on the chosen grounded theory methodology, and may produce different results. This discussion shows that how the differences between using participant observations in classic and constructivist grounded theory can be considerable and that grounded theory researchers should adhere to the method descriptions of performing participant observations according to the selected grounded theory methodology to enhance the quality of research. © 2016 Nordic College of Caring Science.

    2017-02-01

    Emergency medicine (EM) has a high case turnover and acuity making it a demanding clinical reasoning domain especially for junior doctors who lack experience. We aimed to better understand their clinical reasoning using dual cognition as a guiding theory. EM junior doctors were recruited from six hospitals in the south of England to participate in semi-structured interviews (n=20) and focus groups (n=17) based on recall of two recent cases. Transcripts were analysed using a grounded theory approach to identify themes and to develop a model of junior doctors' clinical reasoning in EM. Within cases, clinical reasoning occurred in three phases. In phase 1 (case framing), initial case cues and first impressions were predominantly intuitive, but checked by analytical thought and determined the urgency of clinical assessment. In phase 2 (evolving reasoning), non-analytical single cue and pattern recognitions were common which were subsequently validated by specific analytical strategies such as use of red flags. In phase 3 (ongoing uncertainty) analytical self-monitoring and reassurance strategies were used to precipitate a decision regarding discharge. We found a constant dialectic between intuitive and analytical cognition throughout the reasoning process. Our model of clinical reasoning by EM junior doctors illustrates the specific contextual manifestations of the dual cognition theory. Distinct diagnostic strategies are identified and together these give EM learners and educators a framework and vocabulary for discussion and learning about clinical reasoning.

  15. Superfield theory and supermatrix model

    International Nuclear Information System (INIS)

    Park, Jeong-Hyuck

    2003-01-01

    We study the noncommutative superspace of arbitrary dimensions in a systematic way. Superfield theories on a noncommutative superspace can be formulated in two folds, through the star product formalism and in terms of the supermatrices. We elaborate the duality between them by constructing the isomorphism explicitly and relating the superspace integrations of the star product lagrangian or the superpotential to the traces of the supermatrices. We show there exists an interesting fine tuned commutative limit where the duality can be still maintained. Namely on the commutative superspace too, there exists a supermatrix model description for the superfield theory. We interpret the result in the context of the wave particle duality. The dual particles for the superfields in even and odd spacetime dimensions are D-instantons and D0-branes respectively to be consistent with the T-duality. (author)

    Full Text Available Religiosity has been pluralized and diversified at present era. This study, accepted this presupposition that religiosity as a varied, diverse and instable issue is out of duality of being religiousness or not. By accepting this presupposition we study and interpret one type of religiosity among youth in Isfahan. To achieve the given purpose, by review the previous studies, in interpretive approach, qualitative method framework, Grounded Theory tradition, interview and Simmel theory about religiosity, data is collected. Based on the findings of the study, and with criteria of “self-recognition” we discovered and identified Self referential religiosity. Also, the results of the qualitative data reveal that religiosity of Youth change to: individual, non-compulsory, private, dispositional, and selective, based on self- Intellection, non-accepting heteronomy of religious institution and tend to contingency, hedonistic Phenomena. Finally In this study we also tried to offer, describe and illustrate paradigmatic model of qualitative data in frame of casual, contextual, consequential circumstances about advent and influence this type of religiosity.

    2016-12-01

    This study systematically examined how experienced Speech-Language Pathologists (SLPs) use the processes of reflection to develop knowledge relevant for practice in the context of head and neck cancer (HNC) rehabilitation. In-depth, semi-structured interviews were conducted with 12 SLPs working in HNC rehabilitation in North America. Grounded theory methodology was adopted for data collection and analysis. The findings inform a preliminary reflective practice model that depicts the processes of reflection used by practitioners interviewed. Nine categories of reflective processes were identified by participant SLPs in terms of the processes of reflection: ongoing questioning, experimenting through trial and error, integrating knowledge from past cases, embracing surprise, thinking out of the box, being in the moment, consulting with colleagues, putting oneself in the patients' shoes, and discerning ethical issues. These findings provide empirical evidence that supports Schön's theory of reflective practice and contribute to knowledge about the ways in which SLPs use processes of reflection in the context of HNC rehabilitation. The findings of this study have implications for how SLPs perceive and consider their role as knowledge-users and knowledge producers in their day-to-day clinical work, as well as for building capacity for reflective practice.

    Fatherhood, as a developmental process, is both a human experience and a text that needs to be read. For developing nations like the Philippines, little is known about the process undergone by first-time fathers on their transition to fatherhood, and how nurses can play a significant role in assisting them. This grounded theory study purported to conceptualize the multifaceted process of transition from the lens of Filipino first-time fathers' lived experiences. A total of 20 first-time fathers from Metro Manila, Philippines, were purposively selected to take part in an individual, semistructured, and in-depth interview. The Glaserian (classical) method of analysis was specifically used, and field texts were inductively analyzed using a repertory grid. Member checking and correspondence were done to validate the findings of the study. Six surfacing stages emerged relative to the process of transition. Interestingly, The B.R.I.D.G.E. Theory of First-Time Fatherhood Transition Space describes how these fathers progress from the beholding, reorganizing, inhibiting, delivering, grasping, and embracing phases toward successful transition. This emerged theoretical model can be used in framing health care programs where the needs of fathers during this period are met and addressed. Finally, it can also be used in guiding nurses in their provision of a more empathetic care for first-time fathers. © The Author(s) 2015.

    To give clarity to the analysis of participant observation in nursing when implementing the grounded theory method. Participant observation (PO) is a method of collecting data that reveals the reality of daily life in a specific context. In grounded theory, interviews are the primary method of collecting data but PO gives a distinctive insight, revealing what people are really doing, instead of what they say they are doing. However, more focus is needed on the analysis of PO. An observational study carried out to gain awareness of nursing care and its electronic documentation in four acute care wards in hospitals in Finland. Discussion of using the grounded theory method and PO as a data collection tool. The following methodological tools are discussed: an observational protocol, jotting of notes, microanalysis, the use of questioning, constant comparison, and writing and illustrating. Each tool has specific significance in collecting and analysing data, working in constant interaction. Grounded theory and participant observation supplied rich data and revealed the complexity of the daily reality of acute care. In this study, the methodological tools provided a base for the study at the research sites and outside. The process as a whole was challenging. It was time-consuming and it required rigorous and simultaneous data collection and analysis, including reflective writing. Using these methodological tools helped the researcher stay focused from data collection and analysis to building theory. Using PO as a data collection method in qualitative nursing research provides insights. It is not commonly discussed in nursing research and therefore this study can provide insight, which cannot be seen or revealed by using other data collection methods. Therefore, this paper can produce a useful tool for those who intend to use PO and grounded theory in their nursing research.

  1. On-the-Job Ethics – Proximity Morality Forming in Medical School: A grounded theory analysis using survey data

    Directory of Open Access Journals (Sweden)

    Hans O. Thulesius, MD, Ph.D.

    2009-03-01

    Full Text Available On-the-job-ethics exist in all businesses and can also be called proximity morality forming. In this paper we propose that medical students take a proximity morality stance towards ethics education at medical school. This means that they want to form physician morality “on the job” instead of being taught ethics like any other subject. On-the-job-ethics for medical students involves learning ethics that is used when practicing ethics. Learning ethics includes comprehensive ethics courses in which quality lectures provide ethics grammar useful for the ethics practicing in attitude exercises and vignette reflections in tutored group discussions. On-the-job-ethics develops professional identity, handles diversity of religious and existential worldviews, trains students described as ethically naive, processes difficult clinical experiences, and desists negative role modeling from physicians in clinical or teaching situations. This grounded theory analysis was made from a questionnaire survey on attitudes to ethics education with 409 Swedish medical students participating. We analyzed over 8000 words of open-ended responses and multiplechoice questions using classic grounded theory procedures, but also compared questionnaire data using statistics such as multiple regression models. The paper gives an example of how grounded theory can be used with a limited amount of survey data.

  6. Using Grounded Theory to Analyze Qualitative Observational Data that is Obtained by Video Recording

    Directory of Open Access Journals (Sweden)

    Colin Griffiths

    2013-06-01

    Full Text Available This paper presents a method for the collection and analysis of qualitative data that is derived by observation and that may be used to generate a grounded theory. Video recordings were made of the verbal and non-verbal interactions of people with severe and complex disabilities and the staff who work with them. Three dyads composed of a student/teacher or carer and a person with a severe or profound intellectual disability were observed in a variety of different activities that took place in a school. Two of these recordings yielded 25 minutes of video, which was transcribed into narrative format. The nature of the qualitative micro data that was captured is described and the fit between such data and classic grounded theory is discussed. The strengths and weaknesses of the use of video as a tool to collect data that is amenable to analysis using grounded theory are considered. The paper concludes by suggesting that using classic grounded theory to analyze qualitative data that is collected using video offers a method that has the potential to uncover and explain patterns of non-verbal interactions that were not previously evident.

  7. Multiconfiguration Pair-Density Functional Theory Outperforms Kohn-Sham Density Functional Theory and Multireference Perturbation Theory for Ground-State and Excited-State Charge Transfer.

    2015-08-11

    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.

  8. Transformational change in parenting practices after child interpersonal trauma: A grounded theory examination of parental response.

    Cummings, Jorden A

    2018-02-01

    Child interpersonal trauma is associated with a host of negative outcomes, both concurrently and in adulthood. Parental responses following trauma can play an important role in modulating child responses, symptoms, and post-trauma functioning. However, parents themselves are also impacted after their child experiences trauma, reporting distress, psychopathology, concerns about the child's safety, changes in discipline and protectiveness, and feelings of blame. Most of this previous research, however, suffers from methodological limitations such as focusing on description and correlations, providing static "one shot" assessments of parenting after trauma, and relying mainly on results related to child sexual abuse. This project developed a comprehensive, explanatory theory of the dynamic process by which parenting changes in response to a range of child trauma, using a sample of parents whose children had experienced a range of interpersonal trauma types. Grounded theory analyses revealed a three-phase dynamic model of discontinuous transformation, in which parents experienced destabilization, recalibration, and re-stabilization of parenting practices in response to child trauma. Parents were focused on Protecting and Healing the child victim, often at the expense of their own needs. Most parents reached a phase of posttraumatic growth, labelled Thriving Recovery, but processes that hindered this recovery are also discussed. This study provides the first evidence that dynamic systems of change as well as vicarious posttraumatic growth can apply to parents of child trauma victims. Generating an explanatory theory provides important avenues for future research as well as interventions and services aimed at families who have experienced child trauma. Copyright © 2017 The Author.

  9. New graduate nurses as knowledge brokers in general practice in New Zealand: a constructivist grounded theory.

    Science.gov (United States)

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

    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. © 2013 John Wiley & Sons Ltd.

  10. Sensitivities and uncertainties of modeled ground temperatures in mountain environments

    Directory of Open Access Journals (Sweden)

    2013-08-01

    Full Text Available Model evaluation is often performed at few locations due to the lack of spatially distributed data. Since the quantification of model sensitivities and uncertainties can be performed independently from ground truth measurements, these analyses are suitable to test the influence of environmental variability on model evaluation. In this study, the sensitivities and uncertainties of a physically based mountain permafrost model are quantified within an artificial topography. The setting consists of different elevations and exposures combined with six ground types characterized by porosity and hydraulic properties. The analyses are performed for a combination of all factors, that allows for quantification of the variability of model sensitivities and uncertainties within a whole modeling domain. We found that model sensitivities and uncertainties vary strongly depending on different input factors such as topography or different soil types. The analysis shows that model evaluation performed at single locations may not be representative for the whole modeling domain. For example, the sensitivity of modeled mean annual ground temperature to ground albedo ranges between 0.5 and 4 °C depending on elevation, aspect and the ground type. South-exposed inclined locations are more sensitive to changes in ground albedo than north-exposed slopes since they receive more solar radiation. The sensitivity to ground albedo increases with decreasing elevation due to shorter duration of the snow cover. The sensitivity in the hydraulic properties changes considerably for different ground types: rock or clay, for instance, are not sensitive to uncertainties in the hydraulic properties, while for gravel or peat, accurate estimates of the hydraulic properties significantly improve modeled ground temperatures. The discretization of ground, snow and time have an impact on modeled mean annual ground temperature (MAGT that cannot be neglected (more than 1 °C for several

  11. Models in cooperative game theory

    Branzei, Rodica; Tijs, Stef

    2008-01-01

    This book investigates models in cooperative game theory in which the players have the possibility to cooperate partially. In a crisp game the agents are either fully involved or not involved at all in cooperation with some other agents, while in a fuzzy game players are allowed to cooperate with infinite many different participation levels, varying from non-cooperation to full cooperation. A multi-choice game describes the intermediate case in which each player may have a fixed number of activity levels. Different set and one-point solution concepts for these games are presented. The properties of these solution concepts and their interrelations on several classes of crisp, fuzzy, and multi-choice games are studied. Applications of the investigated models to many economic situations are indicated as well. The second edition is highly enlarged and contains new results and additional sections in the different chapters as well as one new chapter.

  12. Theory of Nonlinear Dispersive Waves and Selection of the Ground State

    Soffer, A.; Weinstein, M.I.

    2005-01-01

    A theory of time-dependent nonlinear dispersive equations of the Schroedinger or Gross-Pitaevskii and Hartree type is developed. The short, intermediate and large time behavior is found, by deriving nonlinear master equations (NLME), governing the evolution of the mode powers, and by a novel multitime scale analysis of these equations. The scattering theory is developed and coherent resonance phenomena and associated lifetimes are derived. Applications include Bose-Einstein condensate large time dynamics and nonlinear optical systems. The theory reveals a nonlinear transition phenomenon, 'selection of the ground state', and NLME predicts the decay of excited state, with half its energy transferred to the ground state and half to radiation modes. Our results predict the recent experimental observations of Mandelik et al. in nonlinear optical waveguides

    Malik, Gulzar; McKenna, Lisa; Griffiths, Debra

    2018-01-01

    Adopting evidence-based practice (EBP) principles in undergraduate education can facilitate nursing students' appreciation of EBP. Using grounded theory method, this study aimed to explore processes used by nurse academics while integrating EBP concepts in undergraduate nursing curricula across Australian universities. Twenty-three nurse academics were interviewed and nine were observed during teaching of undergraduate students. In addition, 20 unit/subject guides were analyzed using grounded theory approach of data analysis. The theory " On a path to success: Endeavoring to contextualize curricula within an EBP framework" reflects academics' endeavors toward linking EBP concepts to practice, aiming to contextualize curricula in a manner that engages students within an EBP framework. However, academics' journeys were influenced by several contextual factors which require strategies to accomplish their endeavors. In conclusion, initiatives to minimize barriers, faculty development, and provision of resources across educational and clinical settings are fundamental to achieving undergraduate curricula underpinned by EBP concepts.

    2014-07-01

    To generate a grounded theory about female adolescent behaviour in the sun. Nurses have key roles in health promotion and skin cancer prevention. Adolescents' resistance to sun safety messages and their vulnerability to sunburn are of concern internationally. Understanding why young women do as they do in the sun may enhance skin cancer prevention, but their behaviour has not been explained before in the UK. The study incorporated a qualitative grounded theory design using the approach of Glaser. Qualitative data were gleaned from group and one-to-one, semi-structured interviews with 20 female participants aged 14-17, research memos and literature. Sampling was purposive and theoretical. Data collection, analysis and theory generation occurred concurrently. Data were analysed using the constant comparative method. Data collection ended when a substantive theory had been generated. Data analysis revealed five categories of findings: fitting in, being myself, being physically comfortable, slipping up and being comfortable (the core category). The theory generated around the core explains how young women direct their sun-related activities towards meeting their physical and psychosocial comfort needs. A contribution of this research is the grounded theory explaining the behaviour of young women in the sun. Further, the theory challenges assumptions that female adolescents necessarily take risks; it explains their sun-related activities in terms of comfort. The theory extends findings from other researchers' descriptive qualitative studies and also appears to apply to young people in countries other than the UK. Understanding the sun-related activity of young women in terms of physical and psychosocial comfort may help nurses to develop new approaches to skin cancer prevention. These could complement existing messages and humanise health promotion. © 2013 John Wiley & Sons Ltd.

    Theoretical studies concerning the connection between critical physical systems and the conformal theories are reviewed. The conformal theory associated to a critical (integrable) lattice model is derived. The obtention of the central charge, critical exponents and torus partition function, using renormalization group arguments, is shown. The quantum group structure, in the integrable lattice models, and the theory of Visaro algebra representations are discussed. The relations between off-critical integrable models and conformal theories, in finite geometries, are studied

    To develop a model for understanding mechanisms of change in health outcomes for riders with disabilities participating in therapeutic horse riding (THR). Using grounded theory methods we collected and analyzed data from interviews with 16 child riders and 18 caregivers, teachers and primary therapists, and from participant-observation during THR sessions. The central concept underpinning the model illustrating mechanisms of change was "gaining the tools to go on." Riders' experiences suggested the THR landscape (i.e., "where the tools are gathered") allowed for an expanded range of experiences in which riders could participate. Riders experienced an expansion of self-concept by learning to move, succeed, connect, and adapt (i.e., "the tools gathered") within the THR landscape. Riders then iteratively translated an expanded view of self into other environments, reflecting "how and where the tools are used." Findings suggest that positive changes in health arise from riders' experiences of learning and agency within the THR therapeutic landscape, and from the influence of these experiences on a child's developing self-concept. This article considers the wider impact of THR on children's health, beyond a focus on changes in physical outcomes.

    International health electives (IHEs) are widely available during residency and provide unique experiences for trainees. Theoretical models of professional identity formation and transformative learning may provide insight into residents' experiences during IHEs. The purpose of this study was to explore transformative learning and professional identity formation during resident IHEs and characterize the relationship between transformative learning and professional identity formation. The authors used a constructivist grounded theory approach, with the sensitizing concepts of transformative learning and professional identity formation to analyze narrative reflective reports of residents' IHEs. The Mayo International Health Program supports residents from all specialties across three Mayo Clinic sites. In 2015, the authors collected narrative reflective reports from 377 IHE participants dating from 2001-2014. Reflections were coded and themes were organized into a model for transformative learning during IHEs, focusing on professional identity. Five components of transformative learning were identified during IHEs: a disorienting experience; an emotional response; critical reflection; perspective change; and a commitment to future action. Within the component of critical reflection three domains relating to professional identity were identified: making a difference; the doctor-patient relationship; and medicine in its "purest form." Transformation was demonstrated through perspective change and a commitment to future action, including continued service, education, and development. IHEs provide rich experiences for transformative learning and professional identity formation. Understanding the components of transformative learning may provide insight into the interaction between learner, experiences, and the influence of mentors in the process of professional identity formation.

    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.

    We analyse modelling techniques for the large-scale structure formed in scalar-tensor theories of constant Brans-Dicke parameter which match the concordance model background expansion history and produce a chameleon suppression of the gravitational modification in high-density regions. Thereby, we use a mass and environment dependent chameleon spherical collapse model, the Sheth-Tormen halo mass function and linear halo bias, the Navarro-Frenk-White halo density profile, and the halo model. Furthermore, using the spherical collapse model, we extrapolate a chameleon mass-concentration scaling relation from a ΛCDM prescription calibrated to N-body simulations. We also provide constraints on the model parameters to ensure viability on local scales. We test our description of the halo mass function and nonlinear matter power spectrum against the respective observables extracted from large-volume and high-resolution N-body simulations in the limiting case of f(R) gravity, corresponding to a vanishing Brans-Dicke parameter. We find good agreement between the two; the halo model provides a good qualitative description of the shape of the relative enhancement of the f(R) matter power spectrum with respect to ΛCDM caused by the extra attractive gravitational force but fails to recover the correct amplitude. Introducing an effective linear power spectrum in the computation of the two-halo term to account for an underestimation of the chameleon suppression at intermediate scales in our approach, we accurately reproduce the measurements from the N-body simulations.

    Field, Richard V., Jr.

    2008-03-01

    Many problems in applied science and engineering involve physical phenomena that behave randomly in time and/or space. Examples are diverse and include turbulent flow over an aircraft wing, Earth climatology, material microstructure, and the financial markets. Mathematical models for these random phenomena are referred to as stochastic processes and/or random fields, and Monte Carlo simulation is the only general-purpose tool for solving problems of this type. The use of Monte Carlo simulation requires methods and algorithms to generate samples of the appropriate stochastic model; these samples then become inputs and/or boundary conditions to established deterministic simulation codes. While numerous algorithms and tools currently exist to generate samples of simple random variables and vectors, no cohesive simulation tool yet exists for generating samples of stochastic processes and/or random fields. There are two objectives of this report. First, we provide some theoretical background on stochastic processes and random fields that can be used to model phenomena that are random in space and/or time. Second, we provide simple algorithms that can be used to generate independent samples of general stochastic models. The theory and simulation of random variables and vectors is also reviewed for completeness.

    2017-03-21

    Medicaid populations are less engaged in their health care than the rest of the population, translating to worse health outcomes and increased health care costs. Since theory-based mobile health (mHealth) interventions have been shown to increase patient engagement, mobile phones may be an optimal strategy to reach this population. With increased development of theory-based mHealth technology, these interventions must now be evaluated with these medically underserved populations in a real-world setting. The aim of our study was to investigate care coordinators' perceived value of using a health behavior theory-based mHealth platform with Medicaid clients. In particular, attention was paid to the perceived impact on patient engagement. This research was conducted using the patient-provider text messaging (short message service, SMS) platform, Sense Health (now Wellpass), which integrates the transtheoretical model (TTM), also called the stages of change model; social cognitive theory (SCT); supportive accountability; and motivational interviewing (MI). Interviews based in grounded theory methodology were conducted with 10 care managers to understand perceptions of the relationship between mHealth and patient engagement. The interviews with care managers yielded a foundation for a grounded theory model, presenting themes that suggested 4 intertwined correlative relationships revolving around patient engagement: (1) A text messaging (short message service, SMS) platform supplements the client-care manager dynamic, which is grounded in high quality, reciprocal-communication to increase patient engagement; (2) Texting enhances the relationship between literacy and access to care for Medicaid patients, increasing low-literacy patients' agency to access services; (3) Texting enhances communication, providing care managers with a new means to support their clients; and (4) Reminders augment client accountability, leading to both increased motivation and readiness to change

    Patient-centered care is both a goal in itself and a tool for enhancing health outcomes. The application of patient-centered care in health care services globally however is diverse. This article reports on a study that sought to introduce patient-centered care. The aim of this study is to explore the process of providing patient-centered care in critical care units. The study used a grounded theory method. Data were collected on 5 critical care units in Tehran University of Medical Sciences. Purposive and theoretical sampling directed the collection of data using 29 semistructured interviews with 27 participants (nurses, patients, and physician). Data obtained were analyzed according to the analysis stages of grounded theory and constant comparison to identify the concepts, context, and process of the study. The core category of this grounded theory is "humanizing care," which consisted of 4 interrelated phases, including patient acceptance, purposeful patient assessment and identification, understanding patients, and patient empowerment. A core category of humanizing care integrated the theory. Humanizing care was an outcome and process. Patient-centered care is a dynamic and multifaceted process provided according to the nurses' understanding of the concept. Patient-centered care does not involve repeating routine tasks; rather, it requires an all-embracing understanding of the patients and showing respect for their values, needs, and preferences.

  13. Quiver gauge theories and integrable lattice models

    International Nuclear Information System (INIS)

    Yagi, Junya

    2015-01-01

    We discuss connections between certain classes of supersymmetric quiver gauge theories and integrable lattice models from the point of view of topological quantum field theories (TQFTs). The relevant classes include 4d N=1 theories known as brane box and brane tilling models, 3d N=2 and 2d N=(2,2) theories obtained from them by compactification, and 2d N=(0,2) theories closely related to these theories. We argue that their supersymmetric indices carry structures of TQFTs equipped with line operators, and as a consequence, are equal to the partition functions of lattice models. The integrability of these models follows from the existence of extra dimension in the TQFTs, which emerges after the theories are embedded in M-theory. The Yang-Baxter equation expresses the invariance of supersymmetric indices under Seiberg duality and its lower-dimensional analogs.

  14. Grounding line transient response in marine ice sheet models

    2013-03-01

    Full Text Available Marine ice-sheet stability is mostly controlled by the dynamics of the grounding line, i.e. the junction between the grounded ice sheet and the floating ice shelf. Grounding line migration has been investigated within the framework of MISMIP (Marine Ice Sheet Model Intercomparison Project, which mainly aimed at investigating steady state solutions. Here we focus on transient behaviour, executing short-term simulations (200 yr of a steady ice sheet perturbed by the release of the buttressing restraint exerted by the ice shelf on the grounded ice upstream. The transient grounding line behaviour of four different flowline ice-sheet models has been compared. The models differ in the physics implemented (full Stokes and shallow shelf approximation, the numerical approach, as well as the grounding line treatment. Their overall response to the loss of buttressing is found to be broadly consistent in terms of grounding line position, rate of surface elevation change and surface velocity. However, still small differences appear for these latter variables, and they can lead to large discrepancies (> 100% observed in terms of ice sheet contribution to sea level when cumulated over time. Despite the recent important improvements of marine ice-sheet models in their ability to compute steady state configurations, our results question the capacity of these models to compute short-term reliable sea-level rise projections.

    Grounding is the art of making an electrical connection to the earth. This paper deals with the analytical and finite element modeling of grounding systems. An electrokinetic formulation using a scalar potential can benefit from floating potentials to define global quantities such as electric voltages and currents. The application concerns a single vertical grounding with one, two and three-layer soil, where the superior extremity stays in the surface of the soil. This problem has been modeled using a 2D axi-symmetric electrokinetic formulation. The grounding resistance obtained by finite element method is compared with the analytical one for one-layer soil. With the results of this paper it is possible to show that finite element method is a powerful tool in the analysis of the grounding systems in low frequencies. (author)

  16. Cluster expansion of the wavefunction. Calculation of electron correlations in ground and excited states by SAC and SAC CI theories

    International Nuclear Information System (INIS)

    Nakatsuji, H.

    1979-01-01

    The SAC and SAC CI theories are formulated for actual calculations of singlet ground states and their excited states of arbitrary spin multiplicity. Approximations are considered for the variational methods since time-consuming terms are involved. The results of test calculations for singlet states have shown, with much smaller numbers of variables (sizes of the matrices involved), excellent agreement with the full CI and close-to-full CI results. This shows the utility of the SAC theory for ground states and especially of the SAC CI theory for excited states, since the slow convergence of the CI theory is much more critical for excited states than for ground states.

  18. "Please. Don't. Die.": A Grounded Theory Study of Bystander Cardiopulmonary Resuscitation.

    Mausz, Justin; Snobelen, Paul; Tavares, Walter

    2018-02-01

    Bystander cardiopulmonary resuscitation (CPR) is an important determinant of survival from out-of-hospital cardiac arrest (OHCA), yet rates of bystander CPR are highly variable. In an effort to promote bystander CPR, the procedure has been streamlined, and ultrashort teaching modalities have been introduced. CPR has been increasingly reconceptualized as simple, safe, and easy to perform; however, current methods of CPR instruction may not adequately prepare lay rescuers for the various logistical, conceptual, and emotional challenges of resuscitating a victim of cardiac arrest. We adopted a constructivist grounded theory methodology to qualitatively explore bystander CPR and invited lay rescuers who had recently (ie, within 1 week) intervened in an OHCA to participate in semistructured interviews and focus groups. We used constant comparative analysis until theoretical saturation to derive a midrange explanatory theory of bystander CPR. We constructed a 3-stage theoretical model describing a common experiential process for lay rescuer intervention in OHCA: Being called to act is disturbing, causing panic, shock, and disbelief that must ultimately be overcome. Taking action to save the victim is complicated by several misconceptions about cardiac arrest, where victims are mistakenly believed to be choking, and agonal respirations are misinterpreted to mean the victim is alive. Making sense of the experience is challenging, at least in the short term, where lay rescuers have to contend with self-doubt, unanswered questions, and uncomfortable emotional reactions to a traumatic event. Our study suggests that current CPR training programs may not adequately prepare lay rescuers for the reality of an OHCA and identifies several key knowledge gaps that should be addressed. The long-term psychological consequences of bystander intervention in OHCA remain poorly understood and warrant further study. © 2018 American Heart Association, Inc.

  19. Understanding the impact of accreditation on quality in healthcare: A grounded theory approach.

    2017-11-01

    To explore how organizations respond to and interact with the accreditation process and the actual and potential mechanisms through which accreditation may influence quality. Qualitative grounded theory study. Organizations who had participated in Accreditation Canada's Qmentum program during January 2014-June 2016. Individuals who had coordinated the accreditation process or were involved in managing or promoting quality. The accreditation process is largely viewed as a quality assurance process, which often feeds in to quality improvement activities if the feedback aligns with organizational priorities. Three key stages are required for accreditation to impact quality: coherence, organizational buy-in and organizational action. These stages map to constructs outlined in Normalization Process Theory. Coherence is established when an organization and its staff perceive that accreditation aligns with the organization's beliefs, context and model of service delivery. Organizational buy-in is established when there is both a conceptual champion and an operational champion, and is influenced by both internal and external contextual factors. Quality improvement action occurs when organizations take purposeful action in response to observations, feedback or self-reflection resulting from the accreditation process. The accreditation process has the potential to influence quality through a series of three mechanisms: coherence, organizational buy-in and collective quality improvement action. Internal and external contextual factors, including individual characteristics, influence an organization's experience of accreditation. © The Author 2017.

    2018-06-01

    Research suggests that the skill and experience of the attendant significantly affect the outcomes of vaginal breech births, yet practitioner experience levels are minimal within many contemporary maternity care systems. Due to minimal experience and cultural resistance, few practitioners offer vaginal breech birth, and many practice guidelines and training programmes recommend delivery techniques requiring supine maternal position. Fewer practitioners have skills to support physiological breech birth, involving active maternal movement and choice of birthing position, including upright postures such as kneeling, standing, squatting, or on a birth stool. How professionals learn complex skills contrary to those taught in their local practice settings is unclear. How do professionals develop competence and expertise in physiological breech birth? Nine midwives and five obstetricians with experience facilitating upright physiological breech births participated in semi-structured interviews. Data were analysed iteratively using constructivist grounded theory methods to develop an empirical theory of physiological breech skill acquisition. Among the participants in this research, the deliberate acquisition of competence in physiological breech birth included stages of affinity with physiological birth, critical awareness, intention, identity and responsibility. Expert practitioners operating across local and national boundaries guided less experienced practitioners. The results depict a specialist learning model which could be formalised in sympathetic training programmes, and evaluated. It may also be relevant to developing competence in other specialist/expert roles and innovative practices. Deliberate development of local communities of practice may support professionals to acquire elusive breech skills in a sustainable way. Copyright © 2017 Australian College of Midwives.

    Zahourek, Rothlyn P

    2005-03-01

    Although intentionality has been implicated as a causal variable in healing research, its definition has been inconsistent and vague. The objective of this grounded theory study is to develop a substantive theory of intentionality in a naturalistic encounter between nurse-healers and their healee-clients, and to consider the implications for practice and research. Six expert nurse-healers and six healee-clients were interviewed as individuals and in dyads before and after treatments. Interviews and observational data were analyzed using the constant comparative method and synthesized analysis. Participants described their experience of intentionality in healing as an evolutionary process characterized by distinctive shifts. The theory of intentionality: the matrix for healing (IMH) includes definitions of intentionality and a conceptual framework of three developmental phases of intentionality (generic, healing, and transforming intentionalities). The predominant attribute, development, is described. The theory contributes to knowledge about healing and intentionality and has implications for practice and future research.

    To develop a theory that explains the 'realities' of part-time nursing. While little is known about the phenomenon of part-time nursing, increasing numbers of nurses work in part-time employment. Grounded theory. The problem that part-time nurses shared was an inability to achieve their personal optimal nursing potential. Motivators to work part-time, employment hours, specialty, individual and organizational factors formed contextual conditions that led to this problem. Part-time nurses responded to the challenges through a process of adaptation and adjustment. Harnessing the full productive potential of part-time nurses requires support to limit the difficulties that they encounter. The developed theory provides a valuable guide to managerial action. Nurse Managers need to consider the developed substantive theory when planning and managing nursing workforces.

    2018-01-01

    Grounded theory was used to generate a mid-range theory of the process of spiritual change in the lives of survivors of homicide victims. Theoretical sampling guided the selection of 30 participants from a larger study of spiritual change after homicide ( N = 112). Individual interviews were analyzed using a four-step sequence of line-by-line, focused, axial, and selective coding. Analysis generated a closed theory consisting of three fluids, consecutive but nonlinear stages. Each stage consisted of an overarching process and a state of being in the world: (a) Disintegrating: living in a state of shock; (b) Reckoning: living in a state of stagnation; (c) Recreating and reintegrating the self: living in a state of renewal. Movement through the stages was fueled by processes of spiritual connection that yielded changes that permeated the theory. Findings can be used to help practitioners address the processes that drive spiritual change in the lives of homicide survivors.

  4. Launch and Landing Effects Ground Operations (LLEGO) Model

    Science.gov (United States)

    2008-01-01

    LLEGO is a model for understanding recurring launch and landing operations costs at Kennedy Space Center for human space flight. Launch and landing operations are often referred to as ground processing, or ground operations. Currently, this function is specific to the ground operations for the Space Shuttle Space Transportation System within the Space Shuttle Program. The Constellation system to follow the Space Shuttle consists of the crewed Orion spacecraft atop an Ares I launch vehicle and the uncrewed Ares V cargo launch vehicle. The Constellation flight and ground systems build upon many elements of the existing Shuttle flight and ground hardware, as well as upon existing organizations and processes. In turn, the LLEGO model builds upon past ground operations research, modeling, data, and experience in estimating for future programs. Rather than to simply provide estimates, the LLEGO model s main purpose is to improve expenses by relating complex relationships among functions (ground operations contractor, subcontractors, civil service technical, center management, operations, etc.) to tangible drivers. Drivers include flight system complexity and reliability, as well as operations and supply chain management processes and technology. Together these factors define the operability and potential improvements for any future system, from the most direct to the least direct expenses.

    Full Text Available With the development of specialized software applications it was possible to approach and resolve complex problems concerning automating and process optimization for which are being used field data. Computerized representation of the shape and dimensions of the Earth requires a detailed mathematical modeling, known as "digital terrain model". The paper aims to present the digital terrain model of Vulcan mining, Hunedoara County, Romania. Modeling consists of a set of mathematical equations that define in detail the surface of Earth and has an approximate surface rigorously and mathematical, that calculated the land area. Therefore, the digital terrain model means a digital representation of the earth's surface through a mathematical model that approximates the land surface modeling, which can be used in various civil and industrial applications in. To achieve the digital terrain model of data recorded using linear and nonlinear interpolation method based on point survey which highlights the natural surface studied. Given the complexity of this work it is absolutely necessary to know in detail of all topographic elements of work area, without the actions to be undertaken to project and manipulate would not be possible. To achieve digital terrain model, within a specialized software were set appropriate parameters required to achieve this case study. After performing all steps we obtained digital terrain model of Vulcan Mine. Digital terrain model is the complex product, which has characteristics that are equivalent to the specialists that use satellite images and information stored in a digital model, this is easier to use.

    Evidence suggests that patients delay reporting symptoms of neutropenic sepsis (NS) despite the risk to their life. This study aimed to elicit factors that contribute to delayed patient reporting of NS symptoms. A constructivist grounded theory study used observations of chemotherapy consultations (13 h) and 31 in-depth interviews to explore beliefs, experiences, and behaviors related to NS. Participants included women with breast cancer, their carers (partners, family, or friends), and clinicians. An explanation for patient delays was developed through theoretical sampling of participants to explore emerging areas of interest and through constant comparison of data and their coding. This entailed iterative and concurrent data collection and analysis. Data were collected until saturation. All patients who developed NS-type symptoms delayed presenting to hospital (2.5 h-8 days), sometimes repeatedly. Moderators of delay included metastatic disease, bereavement, fatalism, religious beliefs, and quality of relationships with clinicians. There was an interplay of behaviors between clinicians, patients, and carers where they subconsciously conspired to underplay the seriousness and possibility of NS occurring. Findings have implications for health risk communication and development of holistic service models. Copyright © 2016 John Wiley & Sons, Ltd.

    Full Text Available Background & Aim: consequences resulting in the increase of the divorce rate in the Iranian society, which surrounded all individuals, families and society, has prepared the background of the present study. The main purpose of the present study was demonstrating a paradigm model of the role of sexual disorder in forming the divorce process among men in Iran. Method: The present study was conducted by applying a qualitative method using the grounded theory approach in Gachsaran, Iran, in 2014. The participants of the study were 15 divorced men who were selected using purposeful sampling. Data were gathered using depth interview, and were analyzed with coding paradigm. Results: according to the coding paradigm, men's sexual dysfunctional as a causal condition, physical disease, mind stress, and age difference between couples as a contextual condition, culture of drug abuse for satisfaction of sexual relation, and infidelity as an interventional condition, caused disorder in their sexual relationship. These men and their wives applied various strategies, such as drug abuse, disconnected sexual relation with each other, and latent violence in order to counteract this phenomenon. Conclusion: The narrative of participants of the present study revealed that disorder in their sexual relation led to other social problems, such as drug abuse, domestic violence, and infidelity in their families. Moreover, these problems led to other disorders in their sexual relationship with their wives, which eventually ended to emotional, sexual and legal divorce.

    2016-01-01

    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.

    Lucas, Heizel Mae; Lozano, Carl James; Valdez, Les Paul; Manzarate, Rowena; Lumawag, Fortuna Angelli Jolyn

    Across the literature, impairment and disability among the older people have been associated with a decline in meeting their special needs. Failure in meeting such needs may cause deterioration of function and threaten successful aging. Accordingly, successful aging studies were carried out among males, in health care institutions, and in communities. In spite of these, the process by which successful aging is experienced by incarcerated older women remains to be a blank spot in research. This study purports to describe the process by which incarcerated older Filipino women experience successful aging. Strauss and Corbin's grounded theory design was employed. Semistructured interviews were conducted among 15 purposively selected incarcerated older Filipino from a Philippine penal institution exclusive for women. Further, data gathered was reduced to field text and was analyzed through open, axial and selective coding. Finally, truthfulness and trustworthiness of the findings were established through member checking. The study generated "The Road to Success Model". Interestingly, five phases relative to successful aging emerged, namely: Struggling, Remotivating, Reforming, Reintegrating and Sustaining. These phases describe how select incarcerated older Filipino women undergo transformation towards successful aging. Similar to a road, each phase is considered a station where one must pass through in order to get to the destination. Findings of the study serve as an impetus for structural and procedural changes in prison, with a view to providing an environment conducive to successful aging and appropriate recognition to the older prisoner's efforts to achieve successful aging.

    Prior qualitative research on gout has focused primarily on barriers to disease management. Our objective was to use patients' perspectives to construct an explanatory framework to understand how patients become engaged in the management of their gout. We recruited a sample of individuals with gout who were participating in a proof-of-concept study of an eHealth-supported collaborative care model for gout involving rheumatology, pharmacy, and dietetics. Semistructured interviews were used. We analyzed transcripts using principles of constructivist grounded theory involving initial coding, focused coding and categorizing, and theoretical coding. Twelve participants with gout (ten males, two females; mean age, 66.5 ± 13.3 years) were interviewed. The analysis resulted in the construction of three themes as well as a framework describing the dynamically linked themes on (1) processing the diagnosis and management of gout, (2) supporting management of gout, and (3) interfering with management of gout. In this framework, patients with gout transition between each theme in the process of becoming engaged in the management of their gout and may represent potential opportunities for healthcare intervention. Findings derived from this study show that becoming engaged in gout management is a dynamic process whereby patients with gout experience factors that interfere with gout management, process their disease and its management, and develop the practical and perceptual skills necessary to manage their gout. By understanding this process, healthcare providers can identify points to adapt care delivery and thereby improve health outcomes.

    We review the formalism by which the tunnelling probability of an unstable ground state can be computed in quantum field theory, with special reference to the Standard Model of electroweak interactions. We describe in some detail the approximations implicitly adopted in such calculation. Particular attention is devoted to the role of scale invariance, and to the different implications of scale-invariance violations due to quantum effects and possible new degrees of freedom. We show that new interactions characterized by a new energy scale, close to the Planck mass, do not invalidate the main conclusions about the stability of the Standard Model ground state derived in absence of such terms.

    Full Text Available Translation can be a problem area for researchers conducting qualitative studies in languages other than English who intend to publish the results in an English-language journal. Analyzing the data is also complex when the research team consists of people from different language backgrounds. Translation must be considered as an issue in its own right to maintain the integrity of the research, especially in a grounded theory study. In this article, we offer guidelines for the process of translation for data analysis in a grounded theory study in which the research was conducted in a language other than English (Indonesian. We make recommendations about procedures to choose when, who, and how to translate data. The translation procedure is divided into four steps which are as follows: translation in the process of coding, translation in the process of team discussion, translation in the process of advanced coding, and ensuring the accuracy of translation.

    Full Text Available While numerous empirical studies have been conducted in Western countries on biotechnology enterprises, little empirical research has been done in Malaysia especially in respect to the factors that contribute to the success of biotechnology small and medium enterprises (SMEs. In view of this, a study was undertaken recently in Malaysia to address this gap in the existing body of biotechnology knowledge. Using a grounded theory approach, this qualitative study managed to develop a conceptual framework that sheds useful information on the enterprise factors that significantly impact the success of Malaysian biotechnology SMEs. Specifically, this study found that organizational structure, innovation activities, linkages with academic research institutions, linkages with other private enterprises, personal linkages with academic researchers, access to financial capital, the procuring of government assistances, vertical integration, enterprise image, GMP compliance and halal certification, strongly influence enterprise success.Keywords: biotechnology, SMEs, Malaysia, success, qualitative study, grounded theory

    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.

    The objective of this study was to develop a substantive grounded theory of staff psychosocial intervention use with residents with dementia in long-stay care. "Becoming a person again" emerged as the core category accounting for staffs' psychosocial intervention use within long-stay care. Interview data were collected from participants in nine Irish long-stay settings: 14 residents with dementia, 19 staff nurses, one clinical facilitator, seven nurse managers, 21 nursing assistants, and five relatives. Constant comparative method guided the data collection and analysis. The researcher's theoretical memos, based on unstructured observation, and applicable extant literature were also included as data. By identifying the mutuality of the participants' experiences, this classic grounded theory explains staff motivation toward psychosocial intervention use within long-stay care. It also explains how institutional factors interact with those personal factors that incline individuals toward psychosocial intervention use. © The Author(s) 2016.

    Full Text Available In this paper I convey a recurring problem and possible solution that arose during my doctoral research on the topic of cross-cultural Holocaust curriculum development for Latvian schools. Specifically, as I devised the methodology for my research, I experienced a number of frustrations concerning the issue of transferability and the limitations of both reader generalizability and grounded theory. Ultimately, I found a more appropriate goal for the external applicability of this and other highly contextual research studies in the form of "grounded understandings," which are tentative apprehensions of the importance or significance of phenomena and conceptualizations that hold meaning and explanatory power, but are only embryonic in their potential to generate theory.

    Nonlinear multiple regression methods are developed to model and analyze groundwater flow systems. Complete descriptions of regression methodology as applied to groundwater flow models allow scientists and engineers engaged in flow modeling to apply the methods to a wide range of problems. Organization of the text proceeds from an introduction that discusses the general topic of groundwater flow modeling, to a review of basic statistics necessary to properly apply regression techniques, and then to the main topic: exposition and use of linear and nonlinear regression to model groundwater flow. Statistical procedures are given to analyze and use the regression models. A number of exercises and answers are included to exercise the student on nearly all the methods that are presented for modeling and statistical analysis. Three computer programs implement the more complex methods. These three are a general two-dimensional, steady-state regression model for flow in an anisotropic, heterogeneous porous medium, a program to calculate a measure of model nonlinearity with respect to the regression parameters, and a program to analyze model errors in computed dependent variables such as hydraulic head.

  3. Ground-state properties of exotic nuclei near Z=40 in the relativistic mean-field theory

    1995-01-01

    Study of the ground-state properties of Kr, Sr and Zr isotopes has been performed in the framework of the relativistic mean-field (RMF) theory using the recently proposed relativistic parameter set NL-SH. It is shown that the RMF theory provides an unified and excellent description of the binding energies, isotope shifts and deformation properties of nuclei over a large range of isospin in the Z=40 region. It is observed that the RMF theory with the force NL-SH is able to describe the anomalous kinks in isotope shifts in Kr and Sr nuclei, the problem which has hitherto remained unresolved. This is in contrast with the density-dependent Skyrme-Hartree-Fock approach which does not reproduce the behaviour of the isotope shifts about shell closure. On the Zr chain we predict that the isotope shifts exhibit a trend similar to that of the Kr and Sr nuclei. The RMF theory also predicts shape coexistence in heavy Sr isotopes. Several dramatic shape transitions in the isotopic chains are shown to be a general feature of nuclei in this region. A comparison of the properties with the available mass models shows that the results of the RMF theory are generally in accord with the predictions of the finite-range droplet model. ((orig.))

    Dilks, Sarah; Tasker, Fiona; Wren, Bernadette

    2008-06-01

    This study set out to explore therapy processes in psychosis with an initial focus on reflexivity and how this might be expressed in therapy conversations. Leiman's (2000) definition of reflexivity was used as a starting-point for an exploratory investigation of the use of language as reflective activity. Grounded theory was chosen as an appropriate methodology to distil an explanatory account across the qualitative data collected. Six psychologist-client pairs supplied three tapes of therapy sessions spread out across the course of therapy. Each participant was separately interviewed on two occasions to ascertain their views of therapy and of the emerging grounded theory. A grounded theory was developed conceptualizing the processes and activities in psychological therapy in psychosis. Building bridges to observational perspectives summarizes the core process in psychological therapy in psychosis. Therapy in psychosis is understood as intimately linking the social and internal world in a dialogical process aimed at enhancing the client's functioning in the social world rather than at specifically developing the private mental experience of reflexivity or mentalizing.

    To develop a grounded theory of nursing's contribution to patient rehabilitation from the perspective of nurses working in inpatient rehabilitation. Grounded theory method, informed by the theoretical perspective of symbolic interactionism, was used to guide data collection and analysis, and the development of a grounded theory. Five inpatient rehabilitation units in Australia. Thirty-five registered and 18 enrolled nurses participated in audio-taped interviews and/or were observed during periods of their everyday practice. The analysis revealed a situation whereby nurses made decisions about when to 'opt in' and when to 'opt out' of inpatient rehabilitation. This occurred on two levels: with their interaction with patients and allied health professionals, and when faced with negative system issues that impacted on their ability to contribute to patient rehabilitation. The primary contribution nurses made to inpatient rehabilitation was working directly with patients, enabling them to self-care. Nurses coached patients when their decisions about 'opting in' and 'opting out' were based on assessment of the person in their particular context. In contrast, the nurses mostly distanced themselves from system-based problems, 'opting out' of addressing them. They did this not to make their working lives easier, but more manageable. System-based problems impacted negatively on the nurses' ability to deliver comprehensive rehabilitation care. As a consequence, some nurses felt unable to influence the care and they withdrew professionally to make their work lives more manageable.

  8. Modeling of earthquake ground motion in the frequency domain

    Science.gov (United States)

    Thrainsson, Hjortur

    In recent years, the utilization of time histories of earthquake ground motion has grown considerably in the design and analysis of civil structures. It is very unlikely, however, that recordings of earthquake ground motion will be available for all sites and conditions of interest. Hence, there is a need for efficient methods for the simulation and spatial interpolation of earthquake ground motion. In addition to providing estimates of the ground motion at a site using data from adjacent recording stations, spatially interpolated ground motions can also be used in design and analysis of long-span structures, such as bridges and pipelines, where differential movement is important. The objective of this research is to develop a methodology for rapid generation of horizontal earthquake ground motion at any site for a given region, based on readily available source, path and site characteristics, or (sparse) recordings. The research includes two main topics: (i) the simulation of earthquake ground motion at a given site, and (ii) the spatial interpolation of earthquake ground motion. In topic (i), models are developed to simulate acceleration time histories using the inverse discrete Fourier transform. The Fourier phase differences, defined as the difference in phase angle between adjacent frequency components, are simulated conditional on the Fourier amplitude. Uniformly processed recordings from recent California earthquakes are used to validate the simulation models, as well as to develop prediction formulas for the model parameters. The models developed in this research provide rapid simulation of earthquake ground motion over a wide range of magnitudes and distances, but they are not intended to replace more robust geophysical models. In topic (ii), a model is developed in which Fourier amplitudes and Fourier phase angles are interpolated separately. A simple dispersion relationship is included in the phase angle interpolation. The accuracy of the interpolation

    Science.gov (United States)

    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

    Health systems in low-income countries are often characterized by poor health outcomes. While many reasons have been advanced to explain the persistently poor outcomes, management of the system has been found to play a key role. According to a WHO framework, the management of health systems is central to its ability to deliver needed health services. In this study, we examined how district managers in a rural setting in Uganda perceived existing approaches to strengthening management so as to provide a pragmatic and synergistic model for improving management capacity building. Twenty-two interviews were conducted with district level administrative and political managers, district level health managers and health facility managers to understand their perceptions and definitions of management and capacity building. Kathy Charmaz's constructive approach to grounded theory informed the data analysis process. An interative, dynamic and complex model with three sub-process of building a competent health manager was developed. A competent manager was understood as one who knew his/her roles, was well informed and was empowered to execute management functions. Professionalizing health managers which was viewed as the foundation, the use of engaging learning approaches as the inside contents and having a supportive work environment the frame of the model were the sub-processes involved in the model. The sub-processes were interconnected although the respondents agreed that having a supportive work environment was more time and effort intensive relative to the other two sub-processes. The model developed in our study makes four central contributions to enhance the WHO framework and the existing literature. First, it emphasizes management capacity building as an iterative, dynamic and complex process rather than a set of characteristics of competent managers. Second, our model suggests the need for professionalization of health managers at different levels of the health

    The analysis of ground state structural and vibrational properties of Safranin-O is presented. The experimental results, obtained by FTIR, Raman and SERS spectroscopy, are discussed in comparison to the results of DFT calculations carried out at the B3LYP/6-311 + G(d,p) level of theory. The calculated spectra reproduce quite satisfactorily the experimental data. The calculated Safranin-O equilibrium structure and the assignment of the vibrational spectra are reported as well. From the changes between Raman and SERS spectra a model is presented for the interaction of Safranin-O with silver nanoparticles.

    Human dynamic models have been used to estimate joint kinetics during various activities. Kinetics estimation is in demand in sports and clinical applications where data on external forces, such as the ground reaction force (GRF), are not available. The purpose of this study was to estimate the GRF during gait by utilizing distance- and velocity-dependent force models between the foot and ground in an inverse-dynamics-based optimization. Ten males were tested as they walked at four different speeds on a force plate-embedded treadmill system. The full-GRF model whose foot-ground reaction elements were dynamically adjusted according to vertical displacement and anterior-posterior speed between the foot and ground was implemented in a full-body skeletal model. The model estimated the vertical and shear forces of the GRF from body kinematics. The shear-GRF model with dynamically adjustable shear reaction elements according to the input vertical force was also implemented in the foot of a full-body skeletal model. Shear forces of the GRF were estimated from body kinematics, vertical GRF, and center of pressure. The estimated full GRF had the lowest root mean square (RMS) errors at the slow walking speed (1.0m/s) with 4.2, 1.3, and 5.7% BW for anterior-posterior, medial-lateral, and vertical forces, respectively. The estimated shear forces were not significantly different between the full-GRF and shear-GRF models, but the RMS errors of the estimated knee joint kinetics were significantly lower for the shear-GRF model. Providing COP and vertical GRF with sensors, such as an insole-type pressure mat, can help estimate shear forces of the GRF and increase accuracy for estimation of joint kinetics.

    The shapes of galaxies are not randomly oriented on the sky. During the galaxy formation and evolution process, environment has a strong influence, as tidal gravitational fields in the large-scale structure tend to align nearby galaxies. Additionally, events such as galaxy mergers affect the relative alignments of both the shapes and angular momenta of galaxies throughout their history. These "intrinsic galaxy alignments" are known to exist, but are still poorly understood. This review will offer a pedagogical introduction to the current theories that describe intrinsic galaxy alignments, including the apparent difference in intrinsic alignment between early- and late-type galaxies and the latest efforts to model them analytically. It will then describe the ongoing efforts to simulate intrinsic alignments using both N-body and hydrodynamic simulations. Due to the relative youth of this field, there is still much to be done to understand intrinsic galaxy alignments and this review summarises the current state of the field, providing a solid basis for future work.

    Budhathoki, S.; Ireson, A. M.

    2017-12-01

    In cold regions, freezing and thawing of the soil govern soil hydraulic properties that shape the surface and subsurface hydrological processes. The partitioning of snowmelt into infiltration and runoff has also important implications for integrated water resource management and flood risk. However, there is an inadequate representation of the snowmelt infiltration into frozen soils in most land-surface and hydrological models, creating the need for improved models and methods. Here we apply, the Frozen Soil Infiltration Model, FroSIn, which is a novel algorithm for infiltration in frozen soils that can be implemented in physically based models of coupled flow and heat transport. In this study, we apply the model in a simple configuration to reproduce observations from field sites in the Canadian prairies, specifically St Denis and Brightwater Creek in Saskatchewan, Canada. We demonstrate the limitations of conventional approaches to simulate infiltration, which systematically over-predict runoff and under predict infiltration. The findings show that FroSIn enables models to predict more reasonable infiltration volumes in frozen soils, and also represent how infiltration-runoff partitioning is impacted by antecedent soil moisture.

    The paper is divided in two parts, the first one having nothing to do with tachyons. In fact, to prepare the ground, in part one (sect. 2) it is shown that special relativity, even without tachyons, can be given a form such to describe both particles and antiparticles. The plan of part two is confined only to a model theory in two dimensions, for the reasons stated in sect. 3

    The symmetric and asymmetric fission path for 240 Pu, 232 Th and 226 Ra is investigated within the relativistic mean-field model. Standard parametrizations which are well fitted to nuclear ground-state properties are found to deliver reasonable qualitative and quantitative features of fission, comparable to similar nonrelativistic calculations. Furthermore, stable octupole deformations in the ground states of radium isotopes are investigated. They are found in a series of isotopes, qualitatively in agreement with nonrelativistic models. But the quantitative details differ amongst the models and between the various relativistic parametrizations. (orig.)

    Grounding plays an important role in transmission line outages and consequently on electric energy transmission quality indexes. Fundamentals of an accurate modelling for transient behaviour analysis, particularly for the response of transmission lines to lightning, are presented. Also, a method to take into account the electromagnetic propagation guided by the grounding electrodes and finally to assess the grounding impedance in order to simulate the transmission line behaviour under lightning is presented. Analysis of impedance behaviour for diverse configurations and simulation results of over voltages on a real 220 kV line are presented to illustrate the capabilities of the method and of the computational program developed

  2. The San Miguel Artist Project: A Grounded Theory of "The Emergence of Wonder"

    Directory of Open Access Journals (Sweden)

    Gordon Medlock

    2015-03-01

    Full Text Available This article employs classical grounded theory methodology to explain the creative process of artists. Two integrally connected core variables are identified: emergence and wonder. Wonder represents the experience that motivates and sustains the creation of works of art, and emergence the process by which the sense of wonder is progressively embodied in the content and form of the work. The theory describes a number of distinct phases, including the experience of wonder, immersion in artistic practice, conceiving a specific work or project, composing the work, presenting the work for an actual or potential audience, and finally moving-on. These phases involve a dynamic stream of recursive processes—sketching, refining, connecting, channeling, and assessing—that ultimately facilitate the emergence of wonder in artistic works. The theory of the emergence of wonder also appears to apply to the research processes of both grounded theory methodology and phenomenology, suggesting that these two research methodologies are more similar and have more in common with the artistic creative process than is commonly acknowledged.

    Decision-making in midwifery, including a claim for shared decision-making between midwives and women, is of major significance for the health of mother and child. Midwives have little information about how to share decision-making responsibilities with women, especially when complications arise during birth. To increase understanding of decision-making in complex home-like birth settings by exploring midwives' and women's perspectives and to develop a dynamic model integrating participatory processes for making shared decisions. The study, based on grounded theory methodology, analysed 20 interviews of midwives and 20 women who had experienced complications in home-like births. The central phenomenon that arose from the data was "defining/redefining decision as a joint commitment to healthy childbirth". The sub-indicators that make up this phenomenon were safety, responsibility, mutual and personal commitments. These sub-indicators were also identified to influence temporal conditions of decision-making and to apply different strategies for shared decision-making. Women adopted strategies such as delegating a decision, making the midwife's decision her own, challenging a decision or taking a decision driven by the dynamics of childbirth. Midwives employed strategies such as remaining indecisive, approving a woman's decision, making an informed decision or taking the necessary decision. To respond to recommendations for shared responsibility for care, midwives need to strengthen their shared decision-making skills. The visual model of decision-making in childbirth derived from the data provides a framework for transferring clinical reasoning into practice. Copyright © 2017 Australian College of Midwives.

    Statistical fluctuations of the nuclear ground state energies are estimated using shell model calculations in which particles in the valence shells interact through well-defined forces, and are coupled to an upper shell governed by random 2-body interactions. Induced ground-state energy fluctuations are found to be one order of magnitude smaller than those previously associated with chaotic components, in close agreement with independent perturbative estimates based on the spreading widths of excited states

    Thulesius, Hans; Barfod, Toke; Ekström, Helene; Håkansson, Anders

    2004-09-30

    Grounded theory (GT) is a popular research method for exploring human behavior. GT was developed by the medical sociologists Glaser and Strauss while they studied dying in hospitals in the 1960s resulting in the book "Awareness of dying". The goal of a GT is to generate conceptual theories by using all types of data but without applying existing theories and hypotheses. GT procedures are mostly inductive as opposed to deductive research where hypotheses are tested. A good GT has a core variable that is a central concept connected to many other concepts explaining the main action in the studied area. A core variable answers the question "What's going on?". Examples of core variables are: "Cutting back after a heart attack"--how people adapt to life after a serious illness; and "Balancing in palliative cancer care"--a process of weighing, shifting, compensating and compromising when treating people with a progressive and incurable illness trajectory.

  6. Collective Inclusioning: A Grounded Theory of a Bottom-Up Approach to Innovation and Leading

    Directory of Open Access Journals (Sweden)

    Michal Lysek

    2016-06-01

    Full Text Available This paper is a grounded theory study of how leaders (e.g., entrepreneurs, managers, etc. engage people in challenging undertakings (e.g., innovation that require everyone’s commitment to such a degree that they would have to go beyond what could be reasonably expected in order to succeed. Company leaders sometimes wonder why their employees no longer show the same responsibility towards their work, and why they are more concerned with internal politics than solving customer problems. It is because company leaders no longer apply collective inclusioning to the same extent as they did in the past. Collective inclusioning can be applied in four ways by convincing, afinitizing, goal congruencing, and engaging. It can lead to fostering strong units of people for taking on challenging undertakings. Collective inclusioning is a complementing theory to other strategic management and leading theories. It offers a new perspective on how to implement a bottom-up approach to innovation.

    Generalist health professionals, often without formal mental health training, provide treatment and care to people with serious mental illness who present with physical health problems in general hospital settings. This article will present findings from a constructivist grounded theory study of the work delivered by generalist health staff to consumers with mental illness on the general medical/surgical wards of two metropolitan hospitals in Sydney, Australia. The results analysed included three participant observations, two focus groups, and 21 interviews and hospital policy and protocol documents. A substantive theory of mental health work in general hospital settings is illustrated which conceptualizes the following categories: (i) the experience: conflicting realities and ideals; (ii) The Context: facilitating social distancing; and (iii) the social processes: invisibility affecting confidence. The categories are understood through the theoretical lens of symbolic interactionism with the theory providing insights into how the generalist health professionals understand their sense of self or identity. © 2018 Australian College of Mental Health Nurses Inc.

However, using participant observations as a data collection method can be done in many ways, depending on the chosen grounded theory methodology, and may produce different results. This discussion shows that how the differences between...

    Background: Qualitative research can help to improve the management of patients, meet their expectations and assist physicians in alleviating their suffering. The perception of moment-to-moment variability in tinnitus annoyance is an emerging field of exploration. This study sought to enlighten variability in tinnitus-induced disablement using a qualitative approach. Methods: Twelve participants (six females, six males, aged 51–79) were recruited via the French Tinnitus Association Journal for participation in recorded semi-structured interviews. Each participant had three interviews lasting 1 h, the sessions being separated one from the other by 2 weeks. Following recommendations of Charmaz (2014), the second and third interviews were aimed at gathering rich data, by enhancing the participants' reflexivity in the circumstances of distress caused by tinnitus. After transcription, the data (n = 36 interviews) were analyzed using the approach to Grounded Theory proposed by Strauss and Corbin (1998). Results: Tinnitus as persistent frustration emerged as being the core category uniting all the other categories of the study. Hence, the core category accounted for the broader scope in participants' experience of chronic tinnitus. It is suggested that tinnitus-induced disablement varied according to the degree of frustration felt by the participants in not being able to achieve their goals. The implications of this were analyzed using the following categories: “Losing body ownership,” “Lacking perspectives,” and “Persevering through difficulties.” Based on these findings, we draw a substantive theory of tinnitus tolerance that promotes an active, disciplined and individualized approach to tinnitus-induced disablement. The model distinguishes pathways from sustained suffering to reduced annoyance (i.e., emerging tolerance). It accounts for difficulties that the participants experienced with a perceived unchanged annoyance over time. Furthermore, this model

    Theory and clinical literature suggest that pride may play an important role in the maintenance of restrictive eating disorders. A grounded theory study explored experiences of, and reflections on, pride among women with a current or past diagnosis of anorexia nervosa. This is a qualitative study using grounded theory. Semistructured interviews were conducted with 21 women recruited from an eating disorder unit in England, and from a UK self-help organization. Grounded theory from a constructivist lens was used. Analysis involved coding, constant comparison, and memo-writing. Pride evolves over the course of anorexia nervosa. Two overarching conceptual categories were identified: 'pride becoming intertwined with anorexia' and 'pride during the journey towards recovery'. These categories encompassed different forms of pride: 'alluring pride', 'toxic pride', 'pathological pride', 'anorexia pride', 'shameful pride', 'recovery pride', and 'resilient pride'. Initially, pride contributed to self-enhancement and buffered negative emotions. As the condition progressed, pride became a challenge to health and interfered with motivation to change. During recovery, perceptions of pride altered as a healthy approach to living ensued. The evolving nature of pride plays a central role in development, maintenance, and treatment of anorexia nervosa. Understanding of pride and its role in psychotherapeutic work with this client group may increase motivation to change and promote recovery. Future work should investigate whether tackling pride in eating disorders increases treatment efficacy and reduces the risk of relapsing. Pride associated with anorexia appeared to evolve in nature. During early stages of the eating disorder, it stopped people from seeking help. Later on, it prevented them from seeing pride in healthy domains of life (outside anorexia). Over time, pride in anorexia became an overwhelming emotion that interfered with motivation to change. It is important for

    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. 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. 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 education, employment and

    Humour is a complex phenomenon, incorporating cognitive, emotional, behavioural, physiological and social aspects. Research to date has concentrated on reviewing (rehearsed) humour and 'healthy' individuals via correlation studies using personality-trait based measurements, principally on psychology students in laboratory conditions. Nurses are key participants in modern healthcare interactions however, little is known about their (spontaneous) humour use. A middle-range theory that accounted for humour use in CNS-patient interactions was the aim of the study. The study reviewed the antecedents of humour exploring the use of humour in relation to (motivational) humour theories. Twenty Clinical Nurse Specialist-patient interactions and their respective peer groups in a country of the United Kingdom. An evolved constructivist grounded theory approach investigated a complex and dynamic phenomenon in situated contexts. Naturally occurring interactions provided the basis of the data corpus with follow-up interviews, focus groups, observation and field notes. A constant comparative approach to data collection and analysis was applied until theoretical sufficiency incorporating an innovative interpretative and illustrative framework. This paper reports the grounded theory and is principally based upon 20 CNS-patient interactions and follow-up data. The negative case analysis and peer group interactions will be reported in separate publications. The theory purports that patients' use humour to reconcile a good patient persona. The core category of the good patient persona, two of its constituent elements (compliance, sycophancy), conditions under which it emerges and how this relates to the use of humour are outlined and discussed. In seeking to establish and maintain a meaningful and therapeutic interaction with the CNS, patients enact a good patient persona to varying degrees depending upon the situated context. The good patient persona needs to be maintained within the

    In recent years, the development of mathematical models for the study of ground shock effects in soil, or rock media, or both, has made important progress. Three basic types of advanced models have been studied: (1) elastic ideally plastic models, (2) variable moduli models and (3) elastic nonideally plastic capped models. The ground shock response in the superseismic range of a 1-MT air burst on a homogeneous halfspace of a soil is considered. Each of the three types of models was fitted to laboratory test data and calculations were made for each case. The results from all three models are comparable only when the stress paths in uniaxial strain are comparable for complete load-unload cycles. Otherwise, major differences occur in the lateral motions and stresses. Consequently, material property laboratory data now include the stress path whenever possible for modeling purposes. (U.S.)

    Nursing students, during their study, experience significant changes on their journey to become nurses. A major change that they experience is the development of their moral competency. The purpose of this study is to explore the process of moral development in Iranian nursing students. A constructivist grounded theory method was adopted. Twenty-five in-depth, semi-structured, face-to-face intensive interviews with 22 participants were conducted from September 2013 to October 2014. All interviews were audio-taped, transcribed, and analyzed using writing memos and the constant comparative method. Participants and research context: The setting was three major nursing schools within Tehran, the capital of Iran. Nineteen nursing students and three lecturers participated in the study. Ethical considerations: The study was approved by the Tehran University of Medical Sciences Committee for Medical Research Ethics (92/D/130/1781). It was explained to all participants that their responses would be treated with confidentiality and that they would not be identified in any way in the research and any publication ensuing from the research. All participants agreed to be interviewed and signed written consent forms agreeing to the recording and analyses of the interview data gathered. Findings indicated three levels of moral development along with the formation of professional identity. The three levels of moral development, getting to know the identity of nursing (moral transition), accepting nursing identity (moral reconstruction), and professional identity internalization (professional morality), were connected to the levels of professional identity formation. The proposed model added a new insight to professionalism in nursing. From the findings, it was concluded that to enhance higher moral practice, nursing instructors should promote the professional identity of nursing students.

    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. PMID:27253389

    Social support and social relationships have been repeatedly identified as essential to nursing home resident quality of life. However, little is known about ways residents develop relationships with peers or staff. This study was conducted to explore the ways resident develop relationships with peers and staff in nursing homes. Fifteen cognitively intact nursing home residents from two facilities were interviewed for this grounded theory study. Sampling, interviewing, and analysis occurred in a cyclical process with results at each stage of the study informing decisions about data collection and analysis in the next. Unstructured interviews and field observations were conducted. Data were analyzed with open, axial, and selective coding. Residents developed relationships with peers and staff largely as an unintended consequence of trying to have a life in the nursing home. Having a life was a two-step process. First, life motivations (Being Self and Creating a Positive Atmosphere) influenced resident preferences for daily activities and interaction goals and subsequently their strategies for achieving and establishing both. Second, the strategies residents used for achieving their required daily activities (Passing Time and Getting Needs Met) and interaction goals then influenced the nature of interaction and the subsequent peer or staff response to these interactions. Residents defined relationships as friendly or unfriendly depending on whether peers or staff responded positively or negatively. There was considerable overlap in the ways peer and staff relationships developed and the results highlight the role of peer and staff responsiveness in relationship development. The results provide possible explanations for the success of interventions in the literature designed to improve staff responsiveness to residents. The results suggest that adapting these kinds of interventions for use with peers may also be successful. The conceptual model also presents a number

    Full Text Available The hereby research encompasses the results of an analysis conducted based on the grounded theory methodology over the qualitative data that were gathered through a national project regarding the organizational development of the mental health institutions. After the finalization of the project, the interest for the grounded theory methodology and the reconsideration of the organizational development notion and of the role of the consultant in this process have all lead to a re-analysis of the qualitative data procured in one of the hospitals included in the project. Our approach resulted in an explanatory model of how the organization works and the factors that can affect various changes during its development. This explanatory model holds at its center a basic psychological and social process that represents the perception of the organizational system as closed on certain coordinates, although structurally open. This very perception and the behavior of maintaining the system within closed coordinates allow only for a dual functioning and so the natural result is the emergence of a self-sufficient culture. The central feature of this particular culture is the replacement of the formal organization and its goal of caring for the mentally challenged with an organization reduced to its sole goal of survival.

    Introduction Policies internationally endorse the recovery paradigm as the appropriate foundation for youth mental health services. However, given that this paradigm is grounded in the views of adults with severe mental illness, applicability to youth services and relevance to young people is uncertain, particularly as little is known about young people’s views. A comprehensive understanding of the experiences and expectations of young people is critical to developing youth mental health services that are acceptable, accessible, effective and relevant. Aim To inform development of policy and youth services, the study described in this protocol aims to develop a comprehensive account of the experiences and expectations of 12–17 year olds as they encounter mental disorders and transition through specialist mental health services. Data will be analysed to model recovery from the adolescents’ perspective. Method and analysis This grounded theory study will use quantitative and qualitative data collected in interviews with 12–17 year olds engaged with specialist Child/Youth Mental Health Service in Queensland, Australia. Interviews will explore adolescents’ expectations and experiences of mental disorder, and of services, as they transition through specialist mental health services, including the meaning of their experiences and ideas of ‘recovery’ and how their experiences and expectations are shaped. Data collection and analysis will use grounded theory methods. Ethics and dissemination Adolescents’ experiences will be presented as a mid-range theory. The research will provide tangible recommendations for youth-focused mental health policy and practice. Findings will be disseminated within academic literature and beyond to participants, health professionals, mental health advocacy groups and policy and decision makers via publications, research summaries, conferences and workshops targeting different audiences.

    Though the United States has become a place of increasing resettlement for refugees, particularly Iraqi refugees who have been forced to flee their homeland due to violence, persecution and civil unrest, little is known about Iraqi refugee resettlement in the United States, or the way in which resettlement impacts health and adjustment. A grounded theory study was conducted to develop a substantive theory of Iraqi refugee resettlement. Participants in the qualitative study included 29 Iraqi refugees and 2 community partners who participated in face-to face interviews. Data analysis and interpretation revealed fundamental concepts related to Iraqi refugee resettlement. Results of analysis showed that for Iraqis choosing to resettle here, the outcome is dichotomous: satisfaction or regret. The outcome is influenced by contextual factors as well as facilitating and hindering intervening conditions during the basic social process of resettlement transition. Each refugee's story is unique, yet all share common threads. This study allowed Iraqi refugees the opportunity to voice their personal experiences of resettling in America, and revealed life stories that inspire and illuminate a process that can guide health care delivery as they cope with the stresses of their journey. As a result, an in-depth storyline was established to explain the process of resettlement for Iraqi refugees. The development of this resettlement theory, grounded in Iraqi refugee experience, has the potential to guide nursing education, enhance the efficacy of practice, inform policy development and form the basis for research.

    Grounded theory. The broader perspective of health offered by the World Health Organization's International Classification of Functioning, Disability and Health has had a significant bearing on how we view the measurement of health outcomes after surgical or therapy interventions for peripheral nerve disorders affecting the hand. The value of the patient's perspective is now recognized and outcomes which reflect this are being advocated in the clinical management and support of this population. This qualitative study sought to explore the lived experience of a hand nerve disorder and in particular the impact on body structure/function, activities, and participation. In depth, one-to-one interviews with 14 people with a range of hand nerve disorders were conducted. Constructivist grounded theory methods were used to collect and analyze the data. Patients were also given the option of taking photographs to visually represent what it is like to live with a nerve disorder, to bring with them for discussion during the interview. The impact of hand nerve disorders forms part of a wider narrative on adaptation. A process of "struggling" and then "overcoming" was experienced. This was followed by an interior aspect of adaptation described as "accepting." This gave rise to participants "transforming," being changed as a result of the journey that they had been on. This study provides an explanatory theory on the adaptive process following a hand nerve disorder which may inform future patient-therapist interactions. Copyright © 2017 Hanley & Belfus.

    Evidence-based nursing is widely recognized as the critical foundation for quality care. To develop a middle-range theory on the process of evidence-based nursing implementation in Chinese context. A grounded theory study using unstructured in-depth individual interviews was conducted with 56 participants who were involved in 24 evidence-based nursing implementation projects in Mainland China from September 2015 to September 2016. A middle-range grounded theory of 'Taking Root' was developed. The theory describes the evidence implementation process consisting of four components (driving forces, process, outcome, sustainment/regression), three approaches (top-down, bottom-up and outside-in), four implementation strategies (patient-centred, nurses at the heart of change, reaching agreement, collaboration) and two patterns (transformational and adaptive implementation). Certain perspectives may have not been captured, as the retrospective nature of the interviewing technique did not allow for 'real-time' assessment of the actual implementation process. The transferability of the findings requires further exploration as few participants with negative experiences were recruited. This is the first study that explored evidence-based implementation process, strategies, approaches and patterns in the Chinese nursing practice context to inform international nursing and health policymaking. The theory of Taking Root described various approaches to evidence implementation and how the implementation can be transformational for the nurses and the setting in which they work. Nursing educators, managers and researchers should work together to improve nurses' readiness for evidence implementation. Healthcare systems need to optimize internal mechanisms and external collaborations to promote nursing practice in line with evidence and achieve clinical outcomes and sustainability. © 2017 International Council of Nurses.

    2017-11-01

    This grounded theory study gathered descriptions the bereavement experience for adults with intellectual disabilities (IDD) through the eyes and voices of a small sample of grief counselors. The counselors described bereaved adults with IDD as individuals who faced potentially heightened effects of the broken attachment bonds, increased risk of coping obstacles, long histories of unrecognized losses, and disenfranchised grief. The participants described bereaved adults with IDD (who sought treatment) as getting pushed to the sidelines to deal with their losses in isolation and confusion. It became evident that though there are many similarities between how all people cope with loss and how people with IDD cope with loss, differences exist. Subtle variations in the experience of loss and grief appear to be driven by culture and beliefs about disability and protection for those with IDD. The participants in this dissertation study contributed foundation data for a theoretical explanation of grief for adults with IDD grounded in data from bereavement counselors.

    Guidelines recommend the use of evidence-based practice in nursing. Nurses are expected to give patients care and treatment based on the best knowledge available. They may have knowledge and positive attitudes, but this does not mean that they are basing their work on evidence-based practice. Knowledge is still lacking about what is needed to successfully implement evidence-based practice. The aim of this study was to gain more knowledge about what nurses perceive as the most important challenge in implementing evidence-based practice and to explain how they act to face and overcome this challenge. We used classical grounded theory methodology and collected data through four focus groups and one individual interview in different geographical locations in one large hospital trust in Norway. Fourteen registered clinical practice nurses participated. We analysed the data in accordance with grounded theory, using the constant comparative method. Contextual balancing of knowledge emerged as the core category and explains how the nurses dealt with their main concern, how to determine what types of knowledge they could trust. The nurses' main strategies were an inquiring approach, examining knowledge and maintaining control while taking care of patients. They combined their own experienced-based knowledge and the guidelines of evidence-based practice with a sense of control in the actual situation. The grounded theory contextual balancing of knowledge may help us to understand how nurses detect what types of knowledge they can trust in clinical practice. The nurses needed to rely on what they did, and they seemed to rely on their own experience rather than on research. © 2015 Nordic College of Caring Science.

  12. Recognizing and responding to uncertainty: a grounded theory of nurses' uncertainty.

    2012-08-01

    There has been little research to date exploring nurses' uncertainty in their practice. Understanding nurses' uncertainty is important because it has potential implications for how care is delivered. The purpose of this study is to develop a substantive theory to explain how staff nurses experience and respond to uncertainty in their practice. Between 2006 and 2008, a grounded theory study was conducted that included in-depth semi-structured interviews. Fourteen staff nurses working in adult medical-surgical intensive care units at two teaching hospitals in Ontario, Canada, participated in the study. The theory recognizing and responding to uncertainty characterizes the processes through which nurses' uncertainty manifested and how it was managed. Recognizing uncertainty involved the processes of assessing, reflecting, questioning, and/or being unable to predict aspects of the patient situation. Nurses' responses to uncertainty highlighted the cognitive-affective strategies used to manage uncertainty. Study findings highlight the importance of acknowledging uncertainty and having collegial support to manage uncertainty. The theory adds to our understanding the processes involved in recognizing uncertainty, strategies and outcomes of managing uncertainty, and influencing factors. Tailored nursing education programs should be developed to assist nurses in developing skills in articulating and managing their uncertainty. Further research is needed to extend, test and refine the theory of recognizing and responding to uncertainty to develop strategies for managing uncertainty. This theory advances the nursing perspective of uncertainty in clinical practice. The theory is relevant to nurses who are faced with uncertainty and complex clinical decisions, to managers who support nurses in their clinical decision-making, and to researchers who investigate ways to improve decision-making and care delivery. ©2012 Sigma Theta Tau International.

    The design of trenches for contaminated ground water recovery must consider several variables. This paper presents a dual-model approach for effectively recovering contaminated ground water migrating toward a trench by advection. The approach involves an analytical model to determine the vertical influence of the trench and a numerical flow model to determine the capture zone within the trench and the surrounding aquifer. The analytical model is utilized by varying trench dimensions and head values to design a trench which meets the remediation criteria. The numerical flow model is utilized to select the type of backfill and location of sumps within the trench. The dual-model approach can be used to design a recovery trench which effectively captures advective migration of contaminants in the vertical and horizontal planes

    The problem of technology acquisition in SMEs represents an under-investigated area in IS research. Most IS literature focuses on either the internal development of systems, which SMEs rarely do, or on issues of usage after the acquisition has taken place. This gap is problematic since acquisition...... grounded theory method for this research. We carried out and analyzed 28 interviews with milk producers and 5 with technology vendors. Our results show that motivations for technology acquisition for milk producers include the economic situation of the farmer, the perceived value of the technology...

    Cell phone mobile application ("app") use has risen dramatically within the past several years. Many individuals access apps to address mental health issues. Unlike individuals from privileged backgrounds, individuals from oppressed backgrounds may rely on apps rather than costly mental health treatment. To date, very little research has been published evaluating mental health apps' effectiveness. This paper focuses on three methods through which grounded theory can facilitate app development and evaluation for people underrepresented in mental health care. Recommendations are made to advance mobile app technology that will help clinicians provide effective treatment, and consumers to realize positive treatment outcomes.

    This paper provides an account of the adverse impacts of domestic violence on women in Kyrgyzstan and develops a grounded theory of coping among survivors of abuse. The results indicate that women adopt a range of strategies to prevent, avert, and minimize anticipated violence. Two key aspects of coping appeared in the narratives: 1) maintaining the status quo and 2) developing agency to resist the abuse. The results suggest that Government and nongovernmental organizations must take additional action to draw women to formal violence prevention services. Providing professional help at several levels (e.g., clinical, community, and societal) and promoting problem-focused strategies as part of therapeutic intervention are essential.

    2017-07-01

    Sixteen fathers of individuals with autism were interviewed to develop a grounded theory explaining how they learned about their children's autism diagnosis. Results suggest the orientation process entails at least two phases: orienting oneself and orienting others. The orienting oneself phase entailed fathers having suspicion of developmental differences, engaging in research and education activities, having their children formally evaluated; inquiring about their children's prognosis, and having curiosities about autism's etiology. The orienting others phase entailed orientating family members and orienting members of their broader communities. Recommendations for responsive service provision, support for fathers, and future research are offered.

    To understand emergency nursing experiences in assisting people with suicidal behavior. Grounded theory study with symbolic interactionism conducted in 2015 to 2016 in Brazil with 19 nurses. Assistance for people with suicidal behavior is critical, challenging, evokes different feelings and requires knowledge, skills and emotional control. Nurses did not feel prepared or supported, and identified recurrent gaps and problems. Nurses occupied a limited role, restricted to attending to physical needs. They predominantly manifested opposition, judgments and incomprehension about patients. This study presents key elements to be addressed in interventions and investigations regarding nursing support, training and supervision. Copyright © 2017 Elsevier Inc. All rights reserved.

    2010-02-01

    Full Text Available Abstract Background Overweight and obesity are considerable public health problems internationally as well as in Sweden. The long-term results of obesity treatment are modest as reported by other studies. The importance of extending the focus to not only comprise obesity treatment but also prevention of weight gain is therefore being emphasized. However, despite the suggested change in focus there is still no consensus on how to prevent obesity or maintain weight. This study reports findings from a qualitative study focusing on attitudes, behaviors and strategies important for primary weight maintenance in a middle-aged population. Methods In depth interviews were conducted with 23 maintainers and four slight gainers in Sweden. The interviews were transcribed and an analysis of weight maintenance was performed using Grounded Theory. Results Based on the informants' stories, describing attitudes, behaviors and strategies of importance for primary weight maintenance, a model illustrating the main findings, was constructed. Weight maintenance was seen as "a tightrope walk" and four strategies of significance for this "tightrope walk" were described as "to rely on heritage", "to find the joy", "to find the routine" and "to be in control". Eleven "ideal types" were included in the model to illustrate different ways of relating to the main strategies. These "ideal types" described more specific attitudes and behaviors such as; eating food that is both tasteful and nutritious, and choosing exercise that provides joy. However, other somewhat contradictory behaviors were also found such as; only eating nutritious food regardless of taste, and being physically active to control stress and emotions. Conclusion This study show great variety with regards to attitudes, strategies and behaviors important for weight maintenance, and considerations need to be taken before putting the model into practice. However, the results from this study can be used within

    Full Text Available In many EFL contexts, including language education milieu in Iran, reading fluency is usually taken for granted since language education in public high schools mainly focuses on reading comprehension. Taking the detrimental effect of fluency deficiency into account, some practitioners foreground reading fluency and try to develop it early on. To give voice to their theories of practice, this qualitative study interviewed teachers who were willing to share their experience with the researchers. In line with grounded theory, the iterative process of data collection and analysis continued until the conceptualization of fluency development techniques was saturated. The techniques emerged are conducive to fluency development and as such the findings have clear implications for practitioners and policy makers nation-wide.

    The goal was to understand the nurse/patient communication process, emphasizing nursing care to mastectomized women. Symbolic Interactionism and Grounded Theory were used to interview eight nurses from a referral institution in cancer treatment, using the guiding question: how do nurses perceive their communication process with mastectomized women? Data analysis allowed for the creation of a central theory: the meaning of communication in nursing care to women, constituted by three distinct but inter-related phenomena: perceiving communication, the relationship nurse/mastectomized woman and rethinking the communication nurse/mastectomized woman. With a view to satisfactory communication, professionals need to get involved and believe that their presence is as important as the performance of technical procedures that relieve situations of stress.

    2012-12-01

    The Caucasus is a region of numerous natural hazards and ensuing disasters. Analysis of the losses due to past disasters indicates the those most catastrophic in the region have historically been due to strong earthquakes. Estimation of expected ground motion is a fundamental earthquake hazard assessment. The most commonly used parameter for attenuation relation is peak ground acceleration because this parameter gives useful information for Seismic Hazard Assessment. Because of this, many peak ground acceleration attenuation relations have been developed by different authors. Besides, a few attenuation relations were developed for Caucasus region: Ambraseys et al. (1996,2005) which were based on entire European region and they were not focused locally on Caucasus Region; Smit et.al. (2000) that was based on a small amount of acceleration data that really is not enough. Since 2003 construction of Georgian Digital Seismic Network has started with the help of number of International organizations, Projects and Private companies. The works conducted involved scientific as well as organizational activities: Resolving technical problems concerning communication and data transmission. Thus, today we have a possibility to get real time data and make scientific research based on digital seismic data. Generally, ground motion and damage are influenced by the magnitude of the earthquake, the distance from the seismic source to site, the local ground conditions and the characteristics of buildings. Estimation of expected ground motion is a fundamental earthquake hazard assessment. This is the reason why this topic is emphasized in this study. In this study new GMP models are obtained based on new data from Georgian seismic network and also from neighboring countries. Estimation of models are obtained by classical, statistical way, regression analysis. Also site ground conditions are considered because the same earthquake recorded at the same distance may cause different damage

    Clinical practice is where student nurses are socialised into a professional role and acquire the distinct behaviour, attitudes and values of the nursing profession. Getting it right at the outset can maximise the development of a professional identity and the transmission of robust value systems. To explore the impact of the first clinical placement on the professional socialisation of adult undergraduate student nurses in the United Kingdom. Data of a longitudinal qualitative nature were collected and analysed using grounded theory. First year student nurses in hospital ward placements comprising a rural District General Hospital and a large inner city Hospital kept daily unstructured diaries for six weeks. A total of 26 undergraduate adult student nurses were purposefully sampled between 2008 and 2010 before undertaking their initial clinical placement. Data collection and analysis used grounded theory and the key question asked of the diarists 'tell me what it is like to be a first year nurse on a first placement' was theoretically adjusted during constant comparison and as the theory emerged. Ethical approval and consent was obtained. The theory of finessing incivility comprises a conceptual framework depicting how student nurses deal with professional incivility during their initial clinical placement and sustain a student identity. Being disillusioned with their role as worker rather than learner yields a sense of 'status dislocation'. Despite needing professional benevolence, they remain altruistic and seek recompense from significant others to negotiate for learning opportunities and relocate their student status. Despite the stressful transition into clinical practice rather than 'fit in', the student nurses want to belong as learners. His or her own resilience to learn nursing and be a professional student maintains their resolve, their altruism and strengthens their existing values to be benevolent towards an indifferent profession.

    To generate a substantive grounded theory of relatives' pattern of behaviour in older patients' fast-track treatment programmes during total hip or knee replacement. Fast-track treatment programmes are designed to make total hip and knee replacements more efficient through recovery improvements. The support of relatives during older patients' trajectory is important. However, knowledge is needed on the relatives' pattern of behaviour to strengthen their involvement in fast-track treatment programmes. We used a Glaserian grounded theory approach based on a systematic generation of theory from data to explain the latent pattern of behaviour of relatives. Data were collected from 2010-2011 in orthopaedic wards at two Danish university hospitals and consisted of 14 non-participant observations, 14 postobservational interviews and five interviews. Seven relatives of patients over 70 years of age participated. The constant comparative method was the guiding principle for simultaneous data collection, data analysis and coding, while theoretically sampling and writing memos. Maintaining Unity emerged as the relatives' pattern of behaviour through which they resolved their main concern: preventing the patients from feeling alone. The relatives resolved their main concern through three interchangeable behavioural modes: Protecting Mode, by providing loving and respectful support; Substituting Mode, with practical and cognitive support; and an Adapting Mode, by trying to fit in with the patients' and health professionals' requirements. The substantive theory of Maintaining Unity offers knowledge of relatives' strong desire to provide compassionate and loving support for the older patients during fast-track treatment programmes. © 2014 John Wiley & Sons Ltd.

  10. Development of Response Spectral Ground Motion Prediction Equations from Empirical Models for Fourier Spectra and Duration of Ground Motion

    In a probabilistic seismic hazard assessment (PSHA) framework, it still remains a challenge to adjust ground motion prediction equations (GMPEs) for application in different seismological environments. In this context, this study presents a complete framework for the development of a response spectral GMPE easily adjustable to different seismological conditions; and which does not suffer from the technical problems associated with the adjustment in response spectral domain. Essentially, the approach consists of an empirical FAS (Fourier Amplitude Spectrum) model and a duration model for ground motion which are combined within the random vibration theory (RVT) framework to obtain the full response spectral ordinates. Additionally, FAS corresponding to individual acceleration records are extrapolated beyond the frequency range defined by the data using the stochastic FAS model, obtained by inversion as described in Edwards & Faeh, (2013). To that end, an empirical model for a duration, which is tuned to optimize the fit between RVT based and observed response spectral ordinate, at each oscillator frequency is derived. Although, the main motive of the presented approach was to address the adjustability issues of response spectral GMPEs; comparison, of median predicted response spectra with the other regional models indicate that presented approach can also be used as a stand-alone model. Besides that, a significantly lower aleatory variability (σbrands it to a potentially viable alternative to the classical regression (on response spectral ordinates) based GMPEs for seismic hazard studies in the near future. The dataset used for the presented analysis is a subset of the recently compiled database RESORCE-2012 across Europe, Middle East and the Mediterranean region.

    2011-12-01

    Full Text Available This paper was written in the beginning phase of my transitioning from grounded theory sociologist (Ekins, 19971 to grounded theory musicologist (Ekins, 20102. In particular, it provides preliminary data for a grounded theory of ‘managing authenticity’, the core category/basic social process (Glaser, 1978 that has emerged from my ongoing grounded theory work in jazz historiography. It was written whilst I was ‘credentialising’ (Glaser, 2010 my transition to popular music studies and popular musicology. In consequence, it incorporates many aspects that are inimical to classic grounded theory. As with so much of Straussian and so-called constructivist grounded theory (Bryant and Charmaz, 2007, it roots itself in G.H. Mead and a social constructivist symbolic interactionism – inter alia, a legitimising (authenticating strategy. Moreover, as is typical of this mode of conceptualising, the paper fills the void of inadequate classic grounded theorising with less conceptual theorising and more conceptual description. Nevertheless, the article does introduce a number of categories that ‘fit and work’, and have ‘conceptual grab’ (Glaser, 1978; Glaser, 1992. In particular, in terms of my own continuing credentialising as a classic grounded theorist, it sets forth important categories to be integrated into my ongoing work on managing authenticity in New Orleans revivalist jazz, namely, ‘trailblazing’, ‘mythologizing’, ‘debunking’, and ‘marginalising’, in the context of the ‘rediscovering’ and ‘resurrecting’ of a jazz pioneer. More specifically, the paper is offered to classic grounded theorists as a contribution to preliminary generic social process analysis in the substantive area of jazz historiography.

    What is known on the subject? The time of discharge from a mental health hospital can be challenging for mental health service users, with high rates of readmission in the immediate months following discharge. Although some research exists that explores service users' perspectives of being discharged, little evidence exists that explores the processes influencing or used by service users' to adapt to the transition from in-patient acute mental health service. What this papers adds to existing knowledge? The findings of this grounded theory study demonstrates the strategies service users used to managed their own, as well as their social audiences, preconceived expectations arising from their new identity as 'psychiatric patients' following their discharge from hospital. While there is a move to develop recovery-orientated mental health services, key indicators of recovery-oriented practices were often absent from service users' experiences of service provision. What are the implications for practice? Nurses and other mental health professionals need to recognize their contribution to the architecture of stigma that transcends the physical structures of hospital or ward and are entrenched within attitudes, interactions and practices. The findings of this study can provide guidance to those working with service users and help them to understand the complexities of their experiences when using mental health services, which go far beyond the management of their symptoms. Following a period of hospitalization, the transition to home can result in increased vulnerability and a source of stress for mental health service users. Readmission rates have been suggested as one indicator of the success of the transition from hospital to community care. Despite knowledge of some of the factors that impact on service users following discharge, no coherent model or theoretical framework could be located in the literature, which explains or aides an in-depth understanding of the

    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.

    There is limited evidence about the effectiveness of occupational therapy interventions for participation outcomes in children with coordination difficulties. Developing theory about the interventions, i.e. their ingredients and change processes, is the first step to advance the evidence base. To develop theory about the key ingredients of occupational therapy interventions for children with coordination difficulties and the processes through which change in participation might happen. Grounded theory methodology, as described by Kathy Charmaz, was used to develop the theory. Children and parents participated in semi-structured interviews to share their experiences of occupational therapy and processes of change. Data collection and analysis were completed concurrently using constant comparison methods. Five key ingredients of interventions were described: performing activities and tasks; achieving; carer support; helping and supporting the child; and labelling. Ingredients related to participation by changing children's mastery experience, increasing capability beliefs and sense of control. Parents' knowledge, skills, positive emotions, sense of empowerment and capability beliefs also related to children's participation. The results identify intervention ingredients and change pathways within occupational therapy to increase participation. It is unclear how explicitly and often therapists consider and make use of these ingredients and pathway.

    Background: There is a lack of theoretical framework supporting stem cell transplant nurses in their assessment, judgment and caring interventions of sibling stem cell donors. Objective: The purpose of this study was to explore sibling stem cell donors’ main concerns and how they deal with them before and after donation. Method: Ten healthy sibling donors, 5 men and 5 women, with a median age of 54 years were included in this study when they were due to donate stem cells to a brother or sister. Data were collected prospectively on three occasions (before the donation and three and twelve months after it) through in-depth interviews, which were recorded and transcribed verbatim for analysis by the Grounded Theory method according to Charmaz. Results: This study describes the efforts of the ten donors to fulfil their duty as a sibling by doing what they considered necessary in order to help. Their efforts were summarised in a process wherein the grounded theory generated three main categories; Prepare, Promote and Preserve. A clear path of transition leading to fulfilment is evident, starting before the donation and continuing for one year afterwards. Conclusions: Being a sibling stem cell donor means doing what you have to do to fulfil your duty and if possible, saving the life of a seriously ill brother or sister. The relationship between the siblings is strengthened by the donation process. Sibling stem cell donation appears to be about fulfilment and the theoretical framework may support clinicians in their evaluation and support of donors. PMID:28839511

    To explore the experiences of young adults with Hodgkin lymphoma during the first year following the end of initial treatment. 
. A qualitative grounded theory study.
. Interviews with patients recruited from three cancer centers in England.
. 10 Hodgkin lymphoma survivors (four men and six women aged 21-39 years) recruited as part of a larger study of 28 young adult cancer survivors.
. Semistructured interviews were conducted about two months after treatment completion, and follow-up interviews were conducted seven months later. The authors' grounded theory of positive psychosocial adjustment to cancer provided the conceptual framework.
. Positive reframing, informal peer support, acceptance, and normalization helped young adults dismantle the threats of Hodgkin lymphoma during the course of treatment. However, they described losing a sense of security following treatment completion. Greater age-specific information to enable better preparation for the future was desired regarding body image, fertility, sexual relationships, work, and socializing.
. Informal support mechanisms, like peer support and patient navigator interventions, may be useful ways to further support young adults after treatment completion.
. Positive psychosocial adjustment to cancer survivorship in young adults is facilitated by having informal peer support; being able to positively reframe, accept, and normalize their experience; and being prepared for the future.

    Uncover how women self-manage their own chronic illness while taking care of a dependent relative. International policies place special emphasis in promoting interventions addressed to control, prevent and care for people with chronic health conditions. Self-management is a crucial part of this care. Caregivers are more prone to have chronic illness than non-caregivers. They are confronted with dilemmas about taking care of themselves while taking care of their dependent relative and the rest of their families. Caregivers articulate strategies to enable them to focus their energy on caring. Qualitative study using constructivist grounded theory. Thirty-nine women caregivers with a chronic illness participated in the study. Twenty-three semi-structured interviews and two focus groups were carried out between April 2010-December 2011. Data were analysed using grounded theory procedures. Self-management helps women caregivers with a chronic illness to balance the demands of their own illness and those of the dependent relative. They self-manage their illness by self-regulating the treatment, by regulating their strength and by controlling their emotions. Women caregivers integrate effectively and creatively the management of their chronic illnesses within the complexities of family care. This renders their health needs invisible and reaffirms them as capable caregivers. Identifying self-management strategies of women caregivers allow health professionals to acknowledge and reinforce effective self-care measures and to deter those that are ineffective and lessen their quality of life. © 2014 John Wiley & Sons Ltd.

    Practice Based Small Group Learning (PBSGL) is an established learning resource for primary care clinicians in Scotland and is used by one-third of general practitioners (GPs). Scottish Government and UK professional bodies have called for GPs and pharmacists to work more closely together to improve care. To gain GPs' and pharmacists' perceptions and experiences of learning together in an inter-professional PBSGL pilot. Qualitative research methods involving established GP PBSGL groups in NHS Scotland recruiting one or two pharmacists to join them. A grounded theory method was used. GPs were interviewed in focus groups by a fellow GP, and pharmacists were interviewed individually by two researchers, neither being a GP or a pharmacist. Interviews were audio-recorded, transcribed and analysed using grounded theory methods. Data saturation was achieved and confirmed. Three themes were identified: GPs' and pharmacists' perceptions and experiences of inter-professional learning; Inter-professional relationships and team-working; Group identity and purpose of existing GP groups. Pharmacists were welcomed into GP groups and both professions valued inter-professional PBSGL learning. Participants learned from each other and both professions gained a wider perspective of the NHS and of each others' roles in the organisation. Inter-professional relationships, communication and team-working were strengthened and professionals regarded each other as peers and friends.

    Governments and professional organizations have called for new partnerships between health care providers and academics to improve clinical education for the benefit of both students and patients. To develop a substantive grounded theory on the process of forming academic-service partnerships in implementing clinical education, from the perspective of academic and clinical nursing staff members and managers working in Iranian settings. The participants included 15 hospital nurses, nurse managers, nurse educators, and educational managers from two central universities and clinical settings from 2009 to 2012. Data were collected through 30 in-depth, semi-structure interviews with the individual participants and then analyzed using the methodology of Strauss and Corbin's grounded theory. Utilizing "balancing power" as the core variable enabled us to integrate the concepts concerning the partnership processes between clinical and educational institutes. Three distinct and significant categories emerged to explain the process of partnership: 1) divergence, 2) conflict between educational and caring functions, and 3) creation of balance between educational and caring functions. In implementing clinical education, partnerships have been formed within a challenging context in Iran. Conflict between clinical and educational functions was the main concern of both sides of the partnership in forming a collaborative relationship, with our findings emphasizing the importance of nursing educators' role in the establishment of partnership programs.

    Full Text Available There is a shortage of clergy, at least in the Roman Catholic Church. Protestant churches in general are experiencing more of a distribution or placement challenge than a shortage. The two greatest hindrances to addressing the Protestant clergy distribution challenge are a lack of adequate compensation for clergy and the undesirable geographical location of a number of churches, as perceived by clergy. Influences such as secularisation, duality of vocation, time management, change in type of ministry, family issues, congregational and denominational conflict, burnout, sexual misconduct, divorce or marital problems, and suicide, affect clergy. Studies on the shortage of clergy have been conducted mostly in the USA and Europe and not in South Africa. This article focuses on the research gap by means of a practical theological grounded theory exploration of the exodus of clergy. Grounded theory methodology is used to identify the reasons why clergy trained at a Bible college of a Protestant charismatic mega church leave full-time pastoral ministry. Findings correspond to previous studies with two reasons appearing more frequently than others: responding to a call and leadership related issues. Firstly, respondents differed in their replies with respect to reconciling their exit from full-time pastoral ministry with their call. The replies included not being called, a dual call, or called but left anyway. Secondly, respondents indicated that leadership influence was mostly negative with regard to affirming their call.

    Abnormal respiratory rates are one of the first indicators of clinical deterioration in emergency department(ED) patients. Despite the importance of respiratory rate observations, this vital sign is often inaccurately recorded on ED observation charts, compromising patient safety. Concurrently, there is a paucity of research reporting why this phenomenon occurs. To develop a substantive theory explaining ED registered nurses' reasoning when they miss or misreport respiratory rate observations. This research project employed a classic grounded theory analysis of qualitative data. Seventy-nine registered nurses currently working in EDs within Australia. Data collected included detailed responses from individual interviews and open-ended responses from an online questionnaire. Classic grounded theory (CGT) research methods were utilised, therefore coding was central to the abstraction of data and its reintegration as theory. Constant comparison synonymous with CGT methods were employed to code data. This approach facilitated the identification of the main concern of the participants and aided in the generation of theory explaining how the participants processed this issue. The main concern identified is that ED registered nurses do not believe that collecting an accurate respiratory rate for ALL patients at EVERY round of observations is a requirement, and yet organizational requirements often dictate that a value for the respiratory rate be included each time vital signs are collected. The theory 'Rationalising Transgression', explains how participants continually resolve this problem. The study found that despite feeling professionally conflicted, nurses often erroneously record respiratory rate observations, and then rationalise this behaviour by employing strategies that adjust the significance of the organisational requirement. These strategies include; Compensating, when nurses believe they are compensating for errant behaviour by enhancing the patient's outcome

  6. Reconstructing constructivism: causal models, Bayesian learning mechanisms, and the theory theory.

    Science.gov (United States)

    Gopnik, Alison; Wellman, Henry M

    2012-11-01

    We propose a new version of the "theory theory" grounded in the computational framework of probabilistic causal models and Bayesian learning. Probabilistic models allow a constructivist but rigorous and detailed approach to cognitive development. They also explain the learning of both more specific causal hypotheses and more abstract framework theories. We outline the new theoretical ideas, explain the computational framework in an intuitive and nontechnical way, and review an extensive but relatively recent body of empirical results that supports these ideas. These include new studies of the mechanisms of learning. Children infer causal structure from statistical information, through their own actions on the world and through observations of the actions of others. Studies demonstrate these learning mechanisms in children from 16 months to 4 years old and include research on causal statistical learning, informal experimentation through play, and imitation and informal pedagogy. They also include studies of the variability and progressive character of intuitive theory change, particularly theory of mind. These studies investigate both the physical and the psychological and social domains. We conclude with suggestions for further collaborative projects between developmental and computational cognitive scientists.

    Packed with new material and research, this second edition of George Friedman’s bestselling Constraint Theory remains an invaluable reference for all engineers, mathematicians, and managers concerned with modeling. As in the first edition, this text analyzes the way Constraint Theory employs bipartite graphs and presents the process of locating the “kernel of constraint” trillions of times faster than brute-force approaches, determining model consistency and computational allowability. Unique in its abundance of topological pictures of the material, this book balances left- and right-brain perceptions to provide a thorough explanation of multidimensional mathematical models. Much of the extended material in this new edition also comes from Phan Phan’s PhD dissertation in 2011, titled “Expanding Constraint Theory to Determine Well-Posedness of Large Mathematical Models.” Praise for the first edition: "Dr. George Friedman is indisputably the father of the very powerful methods of constraint theory...

  8. Realistic Modeling of Seismic Wave Ground Motion in Beijing City

    Science.gov (United States)

    Ding, Z.; Romanelli, F.; Chen, Y. T.; Panza, G. F.

    Algorithms for the calculation of synthetic seismograms in laterally heterogeneous anelastic media have been applied to model the ground motion in Beijing City. The synthetic signals are compared with the few available seismic recordings (1998, Zhangbei earthquake) and with the distribution of observed macroseismic intensity (1976, Tangshan earthquake). The synthetic three-component seismograms have been computed for the Xiji area and Beijing City. The numerical results show that the thick Tertiary and Quaternary sediments are responsible for the severe amplification of the seismic ground motion. Such a result is well correlated with the abnormally high macroseismic intensity zone in the Xiji area associated with the 1976 Tangshan earthquake as well as with the ground motion recorded in Beijing city in the wake of the 1998 Zhangbei earthquake.

    2018-03-01

    This article focuses on developing a ground motion prediction equation based on artificial neural network (ANN) technique for shallow crustal earthquakes. A hybrid technique combining genetic algorithm and Levenberg-Marquardt technique is used for training the model. The present model is developed to predict peak ground velocity, and 5% damped spectral acceleration. The input parameters for the prediction are moment magnitude ( M w), closest distance to rupture plane ( R rup), shear wave velocity in the region ( V s30) and focal mechanism ( F). A total of 13,552 ground motion records from 288 earthquakes provided by the updated NGA-West2 database released by Pacific Engineering Research Center are utilized to develop the model. The ANN architecture considered for the model consists of 192 unknowns including weights and biases of all the interconnected nodes. The performance of the model is observed to be within the prescribed error limits. In addition, the results from the study are found to be comparable with the existing relations in the global database. The developed model is further demonstrated by estimating site-specific response spectra for Shimla city located in Himalayan region.

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

    Science.gov (United States)

    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

    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.

  13. Dignity realization of patients with stroke in hospital care: A grounded theory.

    2017-01-01

    Dignity is seen as an important but complex concept in the healthcare context. In this context, the discussion of dignity includes concepts of other ethical principles such as autonomy and privacy. Patients consider dignity to cover individuality, patient's feelings, communication, and the behavior of healthcare personnel. However, there is a lack of knowledge concerning the realization of patients' dignity in hospital care and the focus of the study is therefore on the realization of dignity of the vulnerable group of patients with stroke. The aim of the study was to create a theoretical construct to describe the dignity realization of patients with stroke in hospital care. Research design and participants: Patients with stroke (n = 16) were interviewed in 2015 using a semi-structured interview containing open questions concerning dignity. The data were analyzed using constant comparison of Grounded Theory. Ethical considerations: Ethical approval for the research was obtained from the Ethics Committee of the University. The permission for the research was given by the hospital. Informed consent was obtained from participants. The "Theory of Dignity Realization of Patients with Stroke in Hospital Care" consists of a core category including generic elements of the new situation and dignity realization types. The core category was identified as "Dignity in a new situation" and the generic elements as health history, life history, individuality and stroke. Dignity of patients with stroke is realized through specific types of realization: person-related dignity type, control-related dignity type, independence-related dignity type, social-related dignity type, and care-related dignity type. The theory has similar elements with the previous literature but the whole construct is new. The theory reveals possible special characteristics in dignity realization of patients with stroke. For healthcare personnel, the theory provides a frame for a better understanding and

    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

    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

    2003-01-01

    Low emittance electron storage rings, such as those used in third generation light sources or linear collider damping rings, rely for their performance on highly stable alignment of the lattice components. Even if all vibration and environmental noise sources could be suppressed, diffusive ground motion will lead to orbit drift and emittance growth. Understanding such motion is important for predicting the performance of a planned accelerator and designing a correction system. A description (known as the ATL model) of ground motion over relatively long time scales has been developed and has become the standard for studies of the long straight beamlines in linear colliders. Here, we show how the model may be developed to include beamlines of any geometry. We apply the model to the NLC and TESLA damping rings, to compare their relative stability under different conditions

    The project will use high-fidelity physics models and simulations to simulate real-time operations of cryogenic and systems and calculate the status/health of the systems. The project enables the delivery of system health advisories to ground system operators. The capability will also be used to conduct planning and analysis of cryogenic system operations. This project will develop and implement high-fidelity physics-based modeling techniques tosimulate the real-time operation of cryogenics and other fluids systems and, when compared to thereal-time operation of the actual systems, provide assessment of their state. Physics-modelcalculated measurements (called “pseudo-sensors”) will be compared to the system real-timedata. Comparison results will be utilized to provide systems operators with enhanced monitoring ofsystems' health and status, identify off-nominal trends and diagnose system/component failures.This capability can also be used to conduct planning and analysis of cryogenics and other fluidsystems designs. This capability will be interfaced with the ground operations command andcontrol system as a part of the Advanced Ground Systems Maintenance (AGSM) project to helpassure system availability and mission success. The initial capability will be developed for theLiquid Oxygen (LO2) ground loading systems.

    Full Text Available 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.

    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. PMID:27172511

    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.

    2015-12-01

    The purpose of this study was to evaluate and potentially modify or expand a previously developed theory: Intentionality: The Matrix of Healing (IMH) using a sample of men in nursing. A modified grounded theory approach described by Chen and Boore (2009) and by Amsteus (2014). Twelve men in nursing were recruited. Each was interviewed at least once and their feedback solicited to determine accuracy of interpretation. Results were compared and contrasted to those obtained from the earlier research with six female nurses and their patients. Both groups viewed intentionality as different from, and greater than, intention. Intentionality reflects the whole person's values, goals, and experiences. The men emphasized the importance of reflective spiritual practices, developing self-awareness, being aware of the stress experienced by males in a female profession, and the role of action in manifesting intentionality in healing. The theory is substantiated with minor changes in emphases. Further study is warranted to expand the understanding of this basic concept in nursing and healing. © The Author(s) 2015.

    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. Copyright © 2013 Elsevier Ltd. All rights reserved.

    The open abdomen (OA) surgical technique has become an option for treating complex abdominal injuries; however, complications leading to late closure conditions might arise. In these cases the wound must be left open, which greatly impacts the patient's life. The author aims to describe the experiences of individuals with a chronic OA wound. Qualitative design using grounded theory was utilized. This study was carried out with a group of 28 adults who were treated with OA technique and whose wound had remained open for more than a month in duration and only received outpatient wound care. Data were collected through open interviews and examined under continuous comparison. The average age of the respondents was 45 years, and their wound, treated with OA due to severe abdominal infection, remained open between 2 months and 8 years. An emergent theory was developed to describe how people facing this experience undergo a process of 4 stages: 1) finding an OA wound upon waking, 2) feeling desperate about the healing process and the limitations involved, 3) regaining control of their life, and 4) taking advantage of their second chance at life with an OA wound. This study provides insight for nurses and other health care professionals into the experiences of patients with a chronic OA wound and proposes an emerging theory based on the conceptualization of these experiences.

    Full Text Available 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.

  10. Brain-grounded theory of temporal and spatial design in architecture and the environment

    Ando, Yoichi

    2016-01-01

    In this book, brain-grounded theory of temporal and spatial design in architecture and the environment is discussed. The author believes that it is a key to solving such global problems as environmental disorders and severe climate change as well as conflicts that are caused by the ill-conceived notion of “time is money”. There are three phases or aspects of a person’s life: the physical life, the spiritual or mental life, and the third stage of life, when a person moves from middle age into old age and can choose what he or she wishes to do instead of simply what must be done. This book describes the temporal design of the environment based on the theory of subjective preference, which could make it possible for an individual to realize a healthy life in all three phases. In his previously published work, the present author wrote that the theory of subjective preference has been established for the sound and visual fields based on neural evidence, and that subjective preference is an overall response o...

    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

    Jørgensen, Lene Bastrup; Fridlund, Bengt

    2016-01-01

    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. 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. The study design used classical grounded theory. The study used a multimodal approach with qualitative and quantitative data sets from 14 patients. 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. 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.

    To explore and explain how nurses minimise risk in the perioperative setting. Perioperative nurses care for patients who are having surgery or other invasive explorative procedures. Perioperative care is increasingly focused on how to improve patient safety. Safety and risk management is a global priority for health services in reducing risk. Many studies have explored safety within the healthcare settings. However, little is known about how nurses minimise risk in the perioperative setting. Classic grounded theory. Ethical approval was granted for all aspects of the study. Thirty-seven nurses working in 11 different perioperative settings in Ireland were interviewed and 33 hr of nonparticipant observation was undertaken. Concurrent data collection and analysis was undertaken using theoretical sampling. Constant comparative method, coding and memoing and were used to analyse the data. Participants' main concern was how to minimise risk. Participants resolved this through engaging in anticipatory vigilance (core category). This strategy consisted of orchestrating, routinising and momentary adapting. Understanding the strategies of anticipatory vigilance extends and provides an in-depth explanation of how nurses' behaviour ensures that risk is minimised in a complex high-risk perioperative setting. This is the first theory situated in the perioperative area for nurses. This theory provides a guide and understanding for nurses working in the perioperative setting on how to minimise risk. It makes perioperative nursing visible enabling positive patient outcomes. This research suggests the need for training and education in maintaining safety and minimising risk in the perioperative setting. © 2017 John Wiley & Sons Ltd.

  14. Societal marketing concept and spirituality in the workplace theory: finding the common ground

    Directory of Open Access Journals (Sweden)

    Anselmo Ferreira Vasconcelos

    Full Text Available This paper suggests that there exist many theoretical linkages between the societal marketing concept (SMC and spirituality in the workplace (SWP theory. Thus, it is reviewed the literature of both SMC and the emerging field of SWP theory in order to find unexplored commonalities between them. As a result, it acknowledges that SMC broached a new perspective in marketing discipline regarding that it added sizeable social and ethical responsibility to the marketer's role. Most importantly, it posits that the common ground between SMC and SWP theory is, in large measure, the moral reasoning. Overall, this study expands McKee's work (2003 on theoretical intersections between marketing and the spirituality philosophy or paradigm. Rather, it proposes that there is a clear evidence of theoretical overlapping in some constructs, namely, employees, work, workplace, quality of life, ethics, corporate citizenship, and social responsibility. In addition, it is also proposed that SMC-driven organizations are poised to embrace an overall spiritual orientation - whether they have not already done it.

    Understanding of underlying mechanisms of drastic variations of the near-Earth space (geospace) is one of the current focuses of the magnetospheric physics. The science target of the geospace research project Exploration of energization and Radiation in Geospace (ERG) is to understand the geospace variations with a focus on the relativistic electron acceleration and loss processes. In order to achieve the goal, the ERG project consists of the three parts: the Arase (ERG) satellite, ground-based observations, and theory/modeling/integrated studies. The role of theory/modeling/integrated studies part is to promote relevant theoretical and simulation studies as well as integrated data analysis to combine different kinds of observations and modeling. Here we provide technical reports on simulation and empirical models related to the ERG project together with their roles in the integrated studies of dynamic geospace variations. The simulation and empirical models covered include the radial diffusion model of the radiation belt electrons, GEMSIS-RB and RBW models, CIMI model with global MHD simulation REPPU, GEMSIS-RC model, plasmasphere thermosphere model, self-consistent wave-particle interaction simulations (electron hybrid code and ion hybrid code), the ionospheric electric potential (GEMSIS-POT) model, and SuperDARN electric field models with data assimilation. ERG (Arase) science center tools to support integrated studies with various kinds of data are also briefly introduced.[Figure not available: see fulltext.

  16. Gauge theories and integrable lattice models

    1989-01-01

    Investigations of new knot polynomials discovered in the last few years have shown them to be intimately connected with soluble models of two dimensional lattice statistical mechanics. In this paper, these results, which in time may illuminate the whole question of why integrable lattice models exist, are reconsidered from the point of view of three dimensional gauge theory. Expectation values of Wilson lines in three dimensional Chern-Simons gauge theories can be computed by evaluating the partition functions of certain lattice models on finite graphs obtained by projecting the Wilson lines to the plane. The models in question - previously considered in both the knot theory and statistical mechanics literature - are IRF models in which the local Boltzmann weights are the matrix elements of braiding matrices in rational conformal field theories. These matrix elements, in turn, can be represented in three dimensional gauge theory in terms of the expectation value of a certain tetrahedral configuration of Wilson lines. This representation makes manifest a surprising symmetry of the braiding matrix elements in conformal field theory. (orig.)

    Full Text Available Abstract 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

  18. Student veterans' construction and enactment of resilience: A constructivist grounded theory study.

    2018-02-01

    WHAT IS KNOWN ON THE SUBJECT?: Resilience is an ability and a process that allows an individual to develop positive adaptation despite challenges and adversities. Many military veterans returning to college after their military service have difficulty transitioning to civilian life. Although some research exists that explores factors related to the resilience of college student veterans, limited theoretical descriptions exist that explain how student veterans construct resilience, and how resilience is enacted and enhanced in their academic and personal (non-academic) lives. WHAT THIS PAPER ADDS TO EXISTING KNOWLEDGE?: The resilience of student veterans involves a complex process of transitioning from military to civilian life and an iterative journey between positive adaptation and transient perturbations. Student veterans' resilience is a result of integrating and resolving various aspects of their academic and personal challenges. WHAT ARE THE IMPLICATIONS FOR PRACTICE?: Nurses can apply this grounded theory as a practical framework for equipping student veterans with effective strategies to develop and enhance resilience. Nurses can employ a holistic approach of care in their interactions with military veterans and student veterans that includes fostering psychological resilience, helping to manage their multiple non-academic responsibilities and supporting their academic success. Introduction Adjusting to college life is one of the most difficult experiences in a military veteran's transition to civilian life. Many military veterans returning to college not only encounter academic challenges, but also deal with physical and psychiatric disabilities, loss of military camaraderie and social disconnect. These often negatively affect their personal and academic lives. Hence, it is important to explore resilience to best support student veterans as they transition from military to civilian life. Aim The aim of this study was to explore how student veterans

    Adhikari, S.K.

    1979-01-01

    A recent work by Rosenberg on cluster states in reaction theory is reexamined and generalized to include energies above the threshold for breakup into four composite fragments. The problem of elastic scattering between two interacting composite fragments is reduced to an equivalent two-particle problem with an effective potential to be determined by extremum principles. For energies above the threshold for breakup into three or four composite fragments effective few-particle potentials are introduced and the problem is reduced to effective three- and four-particle problems. The equivalent three-particle equation contains effective two- and three-particle potentials. The effective potential in the equivalent four-particle equation has two-, three-, and four-body connected parts and a piece which has two independent two-body connected parts. In the equivalent three-particle problem we show how to include the effect of a weak three-body potential perturbatively. In the equivalent four-body problem an approximate simple calculational scheme is given when one neglects the four-particle potential the effect of which is presumably very small

  20. A Unified Model of Cloud-to-Ground Lightning Stroke

    Nag, A.; Rakov, V. A.

    2014-12-01

    The first stroke in a cloud-to-ground lightning discharge is thought to follow (or be initiated by) the preliminary breakdown process which often produces a train of relatively large microsecond-scale electric field pulses. This process is poorly understood and rarely modeled. Each lightning stroke is composed of a downward leader process and an upward return-stroke process, which are usually modeled separately. We present a unified engineering model for computing the electric field produced by a sequence of preliminary breakdown, stepped leader, and return stroke processes, serving to transport negative charge to ground. We assume that a negatively-charged channel extends downward in a stepped fashion through the relatively-high-field region between the main negative and lower positive charge centers and then through the relatively-low-field region below the lower positive charge center. A relatively-high-field region is also assumed to exist near ground. The preliminary breakdown pulse train is assumed to be generated when the negatively-charged channel interacts with the lower positive charge region. At each step, an equivalent current source is activated at the lower extremity of the channel, resulting in a step current wave that propagates upward along the channel. The leader deposits net negative charge onto the channel. Once the stepped leader attaches to ground (upward connecting leader is presently neglected), an upward-propagating return stroke is initiated, which neutralizes the charge deposited by the leader along the channel. We examine the effect of various model parameters, such as step length and current propagation speed, on model-predicted electric fields. We also compare the computed fields with pertinent measurements available in the literature.

  1. Ventromedial prefrontal cortex damage does not impair the development and use of common ground in social interaction: implications for cognitive theory of mind.

    Gupta, Rupa; Tranel, Daniel; Duff, Melissa C

    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.

    1993-01-01

    In the singlet ground-state systems CsFeCl3 and CsFeBr3 a large single-ion anisotropy causes a singlet ground state and a doubly degenerate doublet as the first excited states of the Fe2+ ion. In addition the magneteic interaction is anisotropic being much larger along the z axis than perpendicular...... to it. Therefore, these quasi-one-dimensional magnetic model systems are ideal to demonstrate unique correlation effects. Within the framework of the correlation theory we derive the expressions for the excitation spectrum. When a magnetic field is applied parallel to the z axis both substances have...

    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. © 2013 John Wiley & Sons Ltd.

    A parametric cost model for ground-based telescopes is developed using multivariable statistical analysis of both engineering and performance parameters. While diameter continues to be the dominant cost driver, diffraction-limited wavelength is found to be a secondary driver. Other parameters such as radius of curvature are examined. The model includes an explicit factor for primary mirror segmentation and/or duplication (i.e., multi-telescope phased-array systems). Additionally, single variable models Based on aperture diameter are derived.

    2017-06-01

    Full Text Available Our paper is centered around the formation of theory of institutional modelling that includes principles and ideas reflecting the laws of societal development within the framework of institutional economic theory. We scrutinize and discuss the scientific principles of this institutional modelling that are increasingly postulated by the classics of institutional theory and find their way into the basics of the institutional economics. We propose scientific ideas concerning the new innovative approaches to institutional modelling. These ideas have been devised and developed on the basis of the results of our own original design, as well as on the formalisation and measurements of economic institutions, their functioning and evolution. Moreover, we consider the applied aspects of the institutional theory of modelling and employ them in our research for formalizing our results and maximising the practical outcome of our paper. Our results and findings might be useful for the researchers and stakeholders searching for the systematic and comprehensive description of institutional level modelling, the principles involved in this process and the main provisions of the institutional theory of economic modelling.

    To describe static correlation, we develop a new approach to density functional theory (DFT), which uses a generalized auxiliary system that is of a different symmetry, such as particle number or spin, from that of the physical system. The total energy of the physical system consists of two parts: the energy of the auxiliary system, which is determined with a chosen density functional approximation (DFA), and the excitation energy from an approximate linear response theory that restores the symmetry to that of the physical system, thus rigorously leading to a multideterminant description of the physical system. The electron density of the physical system is different from that of the auxiliary system and is uniquely determined from the functional derivative of the total energy with respect to the external potential. Our energy functional is thus an implicit functional of the physical system density, but an explicit functional of the auxiliary system density. We show that the total energy minimum and stationary states, describing the ground and excited states of the physical system, can be obtained by a self-consistent optimization with respect to the explicit variable, the generalized Kohn-Sham noninteracting density matrix. We have developed the generalized optimized effective potential method for the self-consistent optimization. Among options of the auxiliary system and the associated linear response theory, reformulated versions of the particle-particle random phase approximation (pp-RPA) and the spin-flip time-dependent density functional theory (SF-TDDFT) are selected for illustration of principle. Numerical results show that our multireference DFT successfully describes static correlation in bond dissociation and double bond rotation.

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

    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

    Multi-organ procurement surgical procedures through the generosity of deceased organ donors, have made an enormous impact on extending the lives of recipients. There is a dearth of in-depth knowledge relating to the experiences of perioperative nurses working closely with organ donors undergoing multi-organ procurement surgical procedures. The aim of this study was to address this gap by describing the perioperative nurses experiences of participating in multi-organ procurement surgical procedures and interpreting these findings as a substantive theory. This qualitative study used grounded theory methodology to generate a substantive theory of the experiences of perioperative nurses participating in multi-organ procurement surgery. Recruitment of participants took place after the study was advertised via a professional newsletter and journal. The study was conducted with participants from metropolitan, rural and regional areas of two Australian states; New South Wales and Western Australia. Thirty five perioperative nurse participants with three to 39 years of professional nursing experience informed the study. Semi structured in-depth interviews were undertaken from July 2009 to April 2010 with a mean interview time of 60 min. Interview data was transcribed verbatim and analysed using the constant comparative method. The study results draw attention to the complexities that exist for perioperative nurses when participating in multi-organ procurement surgical procedures reporting a basic social psychological problem articulated as hiding behind a mask and how they resolved this problem by the basic social psychological process of finding meaning. This study provides a greater understanding of how these surgical procedures impact on perioperative nurses by providing a substantive theory of this experience. The findings have the potential to guide further research into this challenging area of nursing practice with implications for clinical initiatives, management

    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.

    Full Text Available The aim of this study was to generate a substantive theory, based on interviews with women with fibromyalgia, explaining how they manage their main concerns in daily life. The study has an inductive approach in line with classic grounded theory (Glaser, 1992. Twenty-three women living in the southwest region of Sweden were interviewed in-depth about their daily living with fibromyalgia and problems related to this. Probing and follow-up questions were asked by the interviewers when relevant. The interviews were transcribed verbatim and consecutively analysed in line with guidelines for grounded theory. The results showed that the main concern for women with fibromyalgia was to reach a balance in daily life. This concern was resolved by them using different strategies aimed at minimizing the dysfunctional interplay between activity and recovery (core category. This imbalance includes that the women are forcing themselves to live a fast-paced life and thereby tax or exceed their physical and psychological abilities and limits. Generally, the fibromyalgia symptoms vary and are most often unpredictable to the women. Pain and fatigue are the most prominent symptoms. However, pain-free periods occur, often related to intense engagement in some activity, relaxation or joy, but mainly the “pain gaps” are unpredictable. To reach a balance in daily life and manage the dysfunctional interplay between activity and recovery the women use several strategies. They are avoiding unnecessary stress, utilizing good days, paying the price for allowing oneself too much activity, planning activities in advance, distracting oneself from the pain, engaging in alleviating physical activities, and ignoring pain sensations. Distracting from the pain seems to be an especially helpful strategy as it may lead to “pain gaps”. This strategy, meaning to divert attention from the pain, is possible to learn, or improve, in health promoting courses based on principles of

  13. Oscillating between Conservation and Investment: A Grounded Theory of Students’ Strategies for Optimizing Personal Resources

    Full Text Available Students’ use of time and effort during their studies has been discussed exhaustively in mass media and educational research. In most cases, researchers try to give advice to teachers on how to get their students to become more active and engaged. The grounded theory presented in this article, however, challenges this approach by focusing on the students’ point of view. When interviewing students for this study, I soon realized that students only have a limited amount of time and effort at their disposal. Optimizing these personal resources emerged as their main concern. For the students, investing resources into one study activity always means having to reduce the amount of time and effort they can spend on other activities. They resolve their main concern by oscillating between conservation and investment strategies. Their decision regarding which type of strategy to use depends strongly on the students’ evaluation of their current situation.

  14. Integration of Qualitative and Quantitative Methods: Building and Interpreting Clusters from Grounded Theory and Discourse Analysis

    Full Text Available Qualitative methods present a wide spectrum of application possibilities as well as opportunities for combining qualitative and quantitative methods. In the social sciences fruitful theoretical discussions and a great deal of empirical research have taken place. This article introduces an empirical investigation which demonstrates the logic of combining methodologies as well as the collection and interpretation, both sequential as simultaneous, of qualitative and quantitative data. Specifically, the investigation process will be described, beginning with a grounded theory methodology and its combination with the techniques of structural semiotics discourse analysis to generate—in a first phase—an instrument for quantitative measuring and to understand—in a second phase—clusters obtained by quantitative analysis. This work illustrates how qualitative methods allow for the comprehension of the discursive and behavioral elements under study, and how they function as support making sense of and giving meaning to quantitative data.

    Terminology around the use of complementary medicines (CM) within medical discourse is ambiguous. Clear collective discourse within the medical context is required. This study reports the findings of a Constructivist Grounded Theory Method study used to explore medical students' conceptualisation of terminology and associated value components around CMs as evidenced within their discourse community. The results show that terminology surrounding CMs within medicine is politically charged and fraught with value judgements. Terms used to describe CMs were considered, many of which were deemed problematic. Categorisation of specific medicines was also deemed inappropriate in certain contexts. Conceptualisation of CM terminology, categorisation and value implications, discriminated between levels of evidence for CMs and provided insights into the social change of medicine towards emergence of an evidence-based integrative approach. The results show that terminology surrounding CM is a social construct consistent with fluid conceptualisation and operationalisation in different social contexts. Copyright © 2015 Elsevier Ltd.

    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. © The Author(s) 2014.

  17. The Temporal Sensitivity of Enforced Accelerated Work Pace: A grounded theory building approach

    Directory of Open Access Journals (Sweden)

    Graham John James Kenealy, BA (Hons, Ph.D. Candidate

    Full Text Available This research explores how a large national UK government organisation copes with radical structural change over time and provides an insight into the temporal effects of ‘Enforced Accelerated Work Pace’ on behaviour and receptivity within an organisational context. The stages of ‘Acceptance’, ‘Reaction’ and‘Withdrawal’ capture the essence of the ‘Coping Reflex Actions relating to Enforced Accelerated Work Pace’, all sensitive to the effects of time. ‘Temporal Sensitivity’; the duration of the changes to work patterns played a large part in the behavioural responses. The underlying logic of this research is grounded theory building, a general method that works well with qualitative data collection approaches and involves inducting insights from field based, case data (Glaser, 1998. A methodology discovered and developed by Glaser and Strauss (1967, negating all others.

    This study explored how nursing students can be kept motivated throughout their clinical education. Motivation is a key issue in nursing clinical education for student retention. The study was conducted using grounded theory methods, which are appropriate when studying process in a social context. Sixteen students and four instructors, who were purposefully selected, participated in semistructured interviews. Data were analyzed using the constant comparative method. Students' motivational journey occurred in three steps: (i) social condition; (ii) encountering the clinical education challenges; and (iii) looking for an escape from nursing, or simply tolerating nursing. Struggling with professional identity emerged as the core variable. Iran's social context and many other conditions in the clinical education setting affect students' motivation. Identifying motivational process might assist educational authorities in offering solutions to promote motivation among students. © 2013 Wiley Publishing Asia Pty Ltd.

    Phantom sensations are somatic phenomena arising from denervated parts of the body. There is very little research, and much diagnostic confusion, regarding such experiences in people with spinal cord injuries. In the case of 'complete' spinal cord lesions, phantom experiences may challenge, and indeed, contradict, the understanding that both clinicians and patients have of such injuries. This paper seeks to provide a better understanding of such 'phantom' sensations in spinal cord injury. We used grounded theory methods to explore 'phantom' sensations as experienced by individuals with complete (ASIA A) spinal lesions. Eight people with complete lesions, who were selected through theoretical sampling, participated in a semi-structured interview. Emergent themes included injury context, sensations experienced, the meaning of sensations, body connectivity, attitude and communication about sensations. Our results provide an enhanced understanding of the embodied experience of phantom sensations, and important insights regarding self-construction and rehabilitative processes in people with spinal cord injury who experience such anomalous sensations.
