Purpose - The purpose of this paper is to assess high-dimensional visualisation, combined with pattern matching, as an approach to observing dynamic changes in the ways people tweet about science topics. Design/methodology/approach - The high-dimensional visualisation approach was applied to three scientific topics to test its effectiveness for longitudinal analysis of message framing on Twitter over two disjoint periods in time. The paper uses coding frames to drive categorisation and visual analytics of tweets discussing the science topics. Findings - The findings point to the potential of this mixed methods approach, as it allows sufficiently high sensitivity to recognise and support the analysis of non-trending as well as trending topics on Twitter. Research limitations/implications - Three topics are studied and these illustrate a range of frames, but results may not be representative of all scientific topics. Social implications - Funding bodies increasingly encourage scientists to participate in public engagement. As social media provides an avenue actively utilised for public communication, understanding the nature of the dialog on this medium is important for the scientific community and the public at large. Originality/value - This study differs from standard approaches to the analysis of microblog data, which tend to focus on machine driven analysis large-scale datasets. It provides evidence that this approach enables practical and effective analysis of the content of midsize to large collections of microposts.

Experimental methods of policy evaluation are well-established in social policy and development eco-nomics but are rare in industrial and innovation policy. In this paper, we consider the arguments forapplying experimental methods to industrial policy measures, and propose an experimental policy eval-uation approach (which we call RCT+). This approach combines the randomised assignment of firmsto treatment and control groups with a longitudinal data collection strategy incorporating quantitativeand qualitative data (so-called mixed methods). The RCT+ approach is designed to provide a causativerather than purely summative evaluation, i.e. to assess both ‘whether’ and ‘how’ programme outcomesare achieved. In this paper, we assess the RCT+ approach through an evaluation of Creative Credits – aUK business-to-business innovation voucher initiative intended to promote new innovation partnershipsbetween SMEs and creative service providers. The results suggest the potential value of the RCT+ approachto industrial policy evaluation, and the benefits of mixed methods and longitudinal data collection.

While storytelling in conversation has been extensively investigated, much less is known about storytelling in the English language classroom, particularly teachers telling their personal experience stories, termed teacher personal narratives in this study. Teacher personal narratives, a combination of the ancient art of human storytelling and the current practices of teaching, offer an innovative approach to language teaching and learning. This thesis examines teacher personal narrative use in Japanese university English language classrooms and is of relevance to both practicing classroom teachers and teacher educators because it explores the role, significance, and effectiveness of personal stories told by teachers. The pedagogical implications which the findings may have for language teaching and learning as well as for teacher education programs are also discussed. Four research questions were posed: 1. What are the characteristics of teacher personal narratives? 2. When, how, and why do language teachers use personal narratives in the classroom? 3. What is the reaction of learners to teacher personal narratives? 4. How do teacher personal narratives provide opportunities for student learning? A mixed methods approach using the tradition of multiple case studies provided an in-depth exploration of the personal narratives of four teachers. Data collection consisted of classroom observations and audio recordings, teacher and student semi-structured interviews, student diaries, and Japan-wide teacher questionnaires. Ninety-seven teacher personal narratives were analyzed for their structural and linguistic features. The findings showed that the narrative elements of orientation, complication, and evaluation are almost always present in these stories, and that discourse and tense markers may aid in student noticing of the input which can lead to eventual student output. The data also demonstrated that reasons for telling narratives mainly fall into two categories: affectiveoriented and pedagogical-oriented purposes. This study has shown that there are significant differences between conversational storytelling and educational storytelling.

The progression of cardiovascular disease (CVD) is largely modifiable through lifestyle behaviours. UK pharmacists are contractually obliged to facilitate patient self-management of chronic conditions such as CVD. Pharmacists are easily accessible health professionals who are well placed to identify “at risk” patients through medication regimes. Research has identified varying attitudes towards and levels of involvement in pharmacist-led health promotion activity. Given the diverse and exploratory nature of the work, a pragmatic, mixed methods approach was used to explore community pharmacists’ role in facilitating patient self-management of CVD. The thesis presents four studies: a qualitative study with pharmacists; a cross sectional questionnaire of community pharmacists; a systematic review and a qualitative study with patients with CVD. The qualitative study with pharmacists gave an insight into pharmacists’ experiences of giving patients with CVD lifestyle advice and the factors underpinning commonly cited barriers to providing public health services. This informed the development of the cross-sectional questionnaire which identified the predictors of pharmacists’ intentions to give two different types of advice to facilitate patient self-management. The systematic review identified a small number of interventions to prepare pharmacists to facilitate patient lifestyle behaviour change and evaluated the theories and behaviour change techniques used in successful interventions; however due to poor study quality and poor reporting of the interventions limited conclusions about the efficacy of the interventions could reliably be drawn. Finally, the qualitative study gave an insight into the experiences of patients with CVD using community pharmacy services and their expectations of the service they receive from community pharmacists. Recommendations about changes to pharmacy policy and practice in order to support pharmacists’ provision of CVD self-management advice are made.

Introduction: There is increasing evidence that electronic prescribing (ePrescribing) or computerised provider/physician order entry (CPOE) systems can improve the quality and safety of healthcare services. However, it has also become clear that their implementation is not straightforward and may create unintended or undesired consequences once in use. In this context, qualitative approaches have been particularly useful and their interpretative synthesis could make an important and timely contribution to the field. This review will aim to identify, appraise and synthesise qualitative studies on ePrescribing/CPOE in hospital settings, with or without clinical decision support. Methods and analysis: Data sources will include the following bibliographic databases: MEDLINE, MEDLINE In Process, EMBASE, PsycINFO, Social Policy and Practice via Ovid, CINAHL via EBSCO, The Cochrane Library (CDSR, DARE and CENTRAL databases), Nursing and Allied Health Sources, Applied Social Sciences Index and Abstracts via ProQuest and SCOPUS. In addition, other sources will be searched for ongoing studies (ClinicalTrials.gov) and grey literature: Healthcare Management Information Consortium, Conference Proceedings Citation Index (Web of Science) and Sociological abstracts. Studies will be independently screened for eligibility by 2 reviewers. Qualitative studies, either standalone or in the context of mixed-methods designs, reporting the perspectives of any actors involved in the implementation, management and use of ePrescribing/CPOE systems in hospital-based care settings will be included. Data extraction will be conducted by 2 reviewers using a piloted form. Quality appraisal will be based on criteria from the Critical Appraisal Skills Programme checklist and Standards for Reporting Qualitative Research. Studies will not be excluded based on quality assessment. A postsynthesis sensitivity analysis will be undertaken. Data analysis will follow the thematic synthesis method. Ethics and dissemination: The study does not require ethical approval as primary data will not be collected. The results of the study will be published in a peer-reviewed journal and presented at relevant conferences.

Interorganizational team research is a growing body of literature and research has started toexamine team related factors such as interorganizational trust (i.e. Stock, 2006) in theinterorganizational setting. This research applies insights from the intraorganizational teamfield into the interorganizational team setting in order to determine the team related factorspertaining to effective collaboration in medical device innovation projects.Interorganizational collaboration has been a persistent feature within the interorganizationalrelations literature, due to the added benefits that can come with working collaborativelytowards a common goal (Berg-Weger & Schnieder, 1998). While much research has exploredthe structures and performance outcomes of engaging in this cross-boundary working, theliterature is sparse with respect to interpersonal relationships, practices and processes leadingto effective collaboration (Bergenholtz & Waldstrom, 2011; Majchrzak, Jarvenpaa & Bargherz,2015). An interpretivist perspective has informed an exploratory mixed methods approach to datacollection, with contextual insights informing each phase of data collection. Three exploratoryphases of data collection have provided (1) qualitative ethnography data, (1i) qualitativeinterview data and (2) quantitative survey data. The NHS has recently set out agendas to increase innovative procurement (Department ofHealth, 2008), work more closely with industry and SMEs (Innovation and Procurement Plan:Department of Health, 2009) and to increase innovative practice (IHW: NHS, 2011). SMEsdeveloping novel medical devices require input from the NHS to ensure that their devices areclinically applicable and therefore will be adopted by the NHS. These contextual insightsprovide the backdrop for Studies 1i and 2. The findings suggest that the intraorganizational team literature can be extended into theinterorganizational collaboration literature, whilst also explaining the factors relating toeffectiveness and success of interorganizational team innovation.

The improving performance of public administration and the reform of public financing system have been on agenda in Hungary for many years, in accordance with the international trends. However, governments have not expected and supported creating of a performance-oriented public administration in a comprehensive and explicit way. Nevertheless, there are bottom-up initiatives at organizational level, which target performance-oriented organizational function. The research focuses on organizations of central public administration where the successful application of performance management methods is most likely based on the international literature. These are the so called agency-type organizations, which are in Hungary called autonomous state-administration organizations independent of the Government (e.g. Hungarian Competition Authority), government bureaus (e.g. Hungarian Central Statistical Office), and central offices subordinated to the government (either the cabinet or a ministry) (e.g. Hungarian Meteorological Service). The studied agencies are legally independent organizations with managerial autonomy based on public law. The purpose of this study is to get an overview on organizational level performance management tools applied by Hungarian agencies, and to reveal the reasons and drivers of the application of these tools. The empirical research is based on a mixed methods approach which combines both quantitative methods and qualitative procedures. The first – quantitative – phase of the author’s research was content analysis of homepages of the studied organizations. As a results she got information about all agencies and their practice related to some performance management tools. The second – qualitative – phase was based on semi-structured face-to-face interviews with some senior managers of agencies. The author selected the interviewees based on the results of the first phase, the relatively strong performance orientation was an important selection criteria.
GRE as a predictor of graduate student success at a Hispanic serving institution of higher education

Accurately predicting the success of graduate students is an important aspect of determining which students should be admitted into graduate programs. The GRE is a pivotal factor to examine since it is one of the most widely used criteria for graduate school admission. Even though the GRE is advertised as an accurate tool for predicting first year graduate GPA, there is a lack of research on long term success factors such as time to degree and graduate rate (Luthy, 1996; Powers, 2004). Furthermore, since most studies have low minority sample sizes, the validity of the GRE may not be the same across all groups (ETS, 2008b; Kuncel, Hezlett, & Ones, 2001). Another gap in GRE studies is that few researchers analyze student characteristics, which may alter or moderate the prediction validity of the GRE. Thus, student characteristics such as degree of academic involvement, mentorship interactions, and other academic and social experiences have not been widely examined in this context. These gaps in the analysis of GRE validity are especially relevant given the high attrition rates within of some graduate programs (e.g., an estimated 68% of doctoral student never complete their programs in urban universities; Lovitts, 2001). A sequential mixed methods design was used to answer the research questions in two phases. The quantitative phase used student data files to analyze the relationship of two success variables (graduation rate and graduate GPA) to the GRE scores as well as other academic and demographic graduate student characteristics. The qualitative phase served to complement the first phase by describing a wider range of characteristics from the 11 graduate students who were interviewed. Both proximal and distal moderators influence student behaviors and success in graduate school. In the first phase of the study, the GRE was the distal facilitator under analysis. Findings suggested that both the GRE Quantitative and the GRE Verbal were predictors of success for master’s students, but the GRE Quantitative was not predictive of success for doctoral students. Other student characteristics such as demographic variables and disciplinary area were also predictors of success for the population of students studied. In the second phase of the study, it was inconclusive whether the GRE was predictive of graduate student success; though it did influence access to graduate programs. Furthermore, proximal moderators such as student involvement, faculty/peer interactions, motivational factors, and program structure were perceived to be facilitators and/or detractors for success.

The number of students identified as having autism increased by 500% in the past 10 years (United States Government Accountability Office, 2005). All students with disabilities are required to be placed in least restrictive environments and to be given access to the general curriculum in the major subjects of math, reading, writing, and science as mandated by federal legislation such as the Individuals with Disabilities Education Act (IDEA, 2004) and No Child Left Behind (NCLB, 2001). As a result of this legislation, an increasing number of students with autism are being educated in inclusive classrooms. Most studies on general education access and curriculum modifications and/or instructional accommodations center on students with intellectual disabilities (e.g. Soukup, Wehmeyer, Bashinski, & Boviard, 2007; Wehmeyer, Lattin, Lapp-Rincker, & Agran, 2003). Wehmeyer et al. (2003) and Soukup et al. (2007) found included students with intellectual disabilities had more access to the general curriculum than mostly self-contained students. This meant included students were more likely to be working on the general curriculum as mandated by NCLB than those in only self-contained classrooms. This study builds and expands the research of Wehmeyer et al., as well as Soukup et al., by examining how students with autism are given access to the general curriculum through curriculum modifications and instructional accommodations used by general education teachers in three schools. This investigation focused on nine inclusive classrooms for students with autism using a parallel mixed methods design (Newman, Newman, & Newman, 2011). Classroom observations using both an IEP related checklist and field notes, teacher interviews, an archival document review of the Individual Education Plan (IEP) for the selected students with autism were performed. Findings of this study were organized by interview questions and subsequent coding categories. Quantitative data were organized in a nominal scale. Participants asserted that their middle school students with autism functioned well in their classrooms, occasionally exhibiting behavioral differences. Most instructional accommodations on IEPs were being implemented by participants, and participants often provided additional instructional accommodations not mandated by the IEP. The majority of participants credited county workshops for their knowledge of instructional accommodations.

Research highlights teacher attrition as one of the biggest challenges facing public schools and their attempts to provide a quality teacher for every student (Ingersoll & Smith, 2003). The teacher shortage is particularly daunting in special education where teachers are over twice as likely to leave the field. The first few years of teaching are the most critical in determining whether or not a beginning teacher will stay in the teaching profession (Whitaker, 2000). ^ A mixed-methods sequential explanatory design was utilized to examine research questions focused on the components of induction support that early career teachers received at their school site, including what they considered most valuable to their long-term retention in the classroom and their development as a quality teacher. Eighty seven early career special education teachers were surveyed during the first phase of the study and six participants were interviewed during the second phase. ^ Data analysis of the Likert-scale survey used in the study revealed that the majority of the respondents received at least 21 of the 25 listed induction components. Moreover, early career special education teachers indicated that they valued all 25 induction components. In addition, findings revealed that over two thirds of the respondents indicated a desire to remain a special education teacher. Overall, early career special education teachers felt confident in their abilities to teach students with disabilities; however, nearly half of the respondents did not feel satisfied with the induction they received. Independent t-tests showed a statistically significant difference between teachers who indicated a desire to remain in special education and those that did not on the level of satisfaction with their induction experience. ^ The six interviews provided elaboration and clarification of the survey responses. The participants expressed their passion for the art of teaching, their dedication to students with disabilities, and their frustration with being a beginning teacher. Furthermore, it was reported that the overall school culture was not very supportive. Participants offered relevant ideas for additional or alternate induction components that would be more effective.^

Prevention scientists have called for more research on the factors affecting the implementation of substance use prevention programs. Given the lack of literature in this area, coupled with evidence that children as early as elementary school engage in substance use, the purpose of this study was to identify the factors that influence the implementation of substance use prevention programs in elementary schools. This study involved a mixed methods approach comprised of a survey and in-person interviews. Sixty-five guidance counselors and teachers completed the survey, and 9 guidance counselors who completed the survey were interviewed individually. Correlation analyses and hierarchical multiple regression were conducted. Quantitative findings revealed ease of implementation most frequently influenced program implementation, followed by beliefs about the program's effectiveness. Qualitative findings showed curriculum modification as an important theme, as well as difficulty of program implementation. The in-person interviews also shed light on three interrelated themes influencing program implementation – The Wheel, time, and scheduling. Results indicate the majority of program providers modified the curriculum in some way. Implications for research, policy, and practice are discussed, and areas for future research are suggested.^

Urban inequality has emerged as one of the dominant themes of modern life and globalization. More than three million people experienced homelessness in the United States last year; in Miami-Dade, more than 15,000 individuals were homeless. Surviving extreme poverty, and exiting or avoiding homelessness, involves negotiating a complex mix of public and private assistance. However, a range of factors influence what types of help are available and how they can be accessed. Frequently, larger social structures determine which resource are available, leaving many choices entirely out of the individual's control. For single men, who are ineligible for many benefits, homelessness can be difficult to avoid and even harder to exit. My study seeks to better understand how adult, minority men living in extreme poverty in Miami-Dade negotiate their daily survival. Specific research questions address: Do black and Hispanic men who are homeless or at risk of homelessness have different personal characteristics and different experiences in avoiding or exiting homelessness? How does Miami's response to extreme poverty/homelessness, including availability of public benefits and public and private service organizations, either maximize or constrain the choices available to this population? And, what is the actual experience of single, adult men who are homeless or at risk of homelessness, in negotiating their daily survival? A mixed methods approach combines quantitative survey data from 7,605 homeless men, with qualitative data from 54 semi-structured interviews incorporating the visual ethnography techniques of Photo Elicitation Interviewing. Results show the differences experienced by black and Hispanic men who are poor and homeless in Miami. Findings also highlight how the community's official and unofficial responses to homelessness intersect with the actual experiences of the persons targeted by the policies and programs, challenging preconceived notions regarding the lives of persons living in extreme poverty. It adds to the existing body of literature by focusing on the urban Miami context, emphasizing disparities amongst racial and ethnic groups. Findings are intended to provide an empirically grounded thesis that humanizes the subjects and illuminates their personal experiences, helping to inform public policy around the needs of extremely poor populations.

The purpose of this study was to compare the efficacy and performance evaluations of alternatively certified first-year teachers to traditionally certified first-year teachers. The participants were 25 first-year teachers in the Broward County Public School District (FL) who completed the Transition to Teaching alternative certification program and a comparison group of 32 first-year teachers in the same school district who completed a traditional university teacher preparation program. ^ The study was a mixed methods design (Creswell, 2003; Tashakkori & Teddlie, 1998). The quantitative data were collected during the 2002–2003 school year using the Teachers' Sense of Efficacy Scale (Tschannen-Moran & Hoy, 2001) and the Florida Performance Measurement System formative and summative instruments. The qualitative data consisted of focus group interviews that were conducted at the end of the 2002–2003 school year. ^ Data were analyzed using independent samples t tests to compare the means of the two populations on their efficacy scores and performance evaluations. Paired samples t tests and analysis of covariance (ANCOVA) were used to compare the efficacy scores for each certification type at the beginning of the school year to the efficacy scores at the end of the school year. A repeated measures analysis of variance (ANOVA) was used to compare the change in the efficacy scores of the teachers from the beginning of the school year to the end of the school year. Focus group interviews were conducted and transcribed, and the content was analyzed and categorized based on the four sources of self-efficacy described by Bandura (1986, 1997). ^ The results of this study revealed that no statistically significant differences existed between the two groups of teachers in their teacher efficacy or performance evaluations and that they reported similar sources of their efficacy. These findings add to the research base that supports alternative certification as a viable and effective pathway into teaching. ^
