Is It a Small World after all: An Examination of Scientific Collaborations in Public Administration

Orr, James Earl, Jr 15 December 2012 (has links)
Peer reviewed journal articles are one way in which scholars communicate with each other and the public. Such publications create networks of collaboration. This study uses social network analysis techniques and theory to examine the network of collaborations that occur in public administration. Social network analysis is a perspective that takes into account the structure of relationships that can exist among individuals, organizations or other entities (Wellman, 2008). The small world theory is the specific theoretical framework that guides this study. The small world theory is based on the notion that despite a population being very large, individuals in that population are still connected with each other within a few steps. The author constructs a scientific network of research collaborations by assigning a relationship to two actors who have co-published an article together in the Public Administration Review, American Review of Public Administration, or The Review of Public Personnel Administration during the time periods of January 2003- December 2011. The results of this analysis reveal that the public administration network consists primarily of faculty members. The network also exhibits a high degree of clustering and several cliques. On average, individuals in the network are only slightly farther apart from each other than what would be expected in a small world network. This research contributes to public administration by introducing scientific networks of collaboration to public administration. The field has not ignored who publishes in its journals, but it has not used network analysis techniques to examine such publications. This study demonstrates how network analysis techniques and methodology can be used to examine a large network. Finally, this research contributes to the small world theory by applying it to scientific networks in public administration.

Initial insights into the impact and implementation of Creating Active Schools in Bradford, UK

Morris, Jade L., Chalkley, Anna, Helme, Zoe, Timms, O., Young, Emma, McLoughlin, G.M., Bartholomew, J.B., Daly-Smith, Andrew 10 July 2023 (has links)
Yes / Few whole-school physical activity programmes integrate implementation science frameworks within the design, delivery, and evaluation. As a result, knowledge of the key factors that support implementation at scale is lacking. The Creating Active Schools (CAS) programme was co-designed and is underpinned by the Capability, Opportunity, Motivation and Behaviour (COM-B) model and the Consolidated Framework for Implementation Research (CFIR). The study aims to understand the initial impact and implementation of CAS in Bradford over 9 months using McKay's et al.'s (2019) implementation evaluation roadmap. Focus groups and interviews were conducted with school staff (n = 30, schools = 25), CAS Champions (n = 9), and the CAS strategic lead (n = 1). Qualitative data were analysed both inductively and deductively. The deductive analysis involved coding data into a priori themes based on McKay et al's implementation evaluation roadmap, using a codebook approach to thematic analysis. The inductive analysis included producing initial codes and reviewing themes before finalising. Identified themes aligned into three categories: (i) key ingredients for successful adoption and implementation of CAS, (ii) CAS implementation: challenges and solutions, and (iv) the perceived effectiveness of CAS at the school level. This included the willingness of schools to adopt and implement whole-school approaches when they are perceived as high quality and aligned with current school values. The programme implementation processes were seen as supportive; schools identified and valued the step-change approach to implementing CAS long-term. Formal and informal communities of practice provided "safe spaces" for cross-school support. Conversely, challenges persisted with gaining broader reach within schools, school staff's self-competence and shifting school culture around physical activity. This resulted in varied uptake between and within schools. This study provides novel insights into the implementation of CAS, with outcomes aligning to the adoption, reach, and sustainability. Successful implementation of CAS was underpinned by determinants including acceptability, intervention complexity, school culture and school stakeholders' perceived self-efficacy. The combination of McKay's evaluation roadmap and CFIR establishes a rigorous approach for evaluating activity promotion programmes underpinned by behavioural and implementation science. Resultantly this study offers originality and progression in understanding the implementation and effectiveness of whole-school approaches to physical activity. / Higher Education Innovation Fund (UKRI), Sport England’s Local Delivery Pilot in Bradford, Bradford District Metropolitan Council via the Living Well Programme / Research Development Fund Publication Prize Award winner, Jun 2023.

Establishing a Special Interest City Magazine: D, the Magazine of Dallas

Glaves, Robert F. 12 1900 (has links)
The problem of this study was to determine how, and to what degree, a representative contemporary special interest magazine projected editorial, advertising, circulation, and financial obligations prior to publication and during its infancy. In essence, how did a representative nonsubsidized city magazine identify a marketable audience, resolve advertising and circulation policies, and meet financial obligations? Specifically, this study explored--in six chapters--the mechanics of pre- and post-publication planning at D, The Magazine of Dallas, which began publication in October, 1974. This study determined that twelve common denominators are essential, but are not necessarily a guarantee, for the success of a planned or newly introduced nonsubsidized special interest magazine.

Les enseignants-chercheurs en gestion à l'épreuve des nouvelles injonctions institutionnelles en matière d'évaluation : une étude France-Québec / Academics put to the test of new institutional injunctions : A study between France and Quebec

Lussier, Sacha 07 March 2014 (has links)
La thèse vise à comprendre le lien existant entre les classements internationaux, le système de publication ainsi que les acteurs de l'enseignement et de la recherche en gestion. Nous approfondirons leurs relations en nous basant sur la théorie de la structuration de Giddens et les concepts d'habitus et de champ chez Bourdieu. Les classements construisent des indicateurs de performance généralement basés sur les articles dans des revues scientifiques internationales. Les critères des classements sont internalisés par les établissements et influencent leur stratégie ainsi que leur système d'évaluation. C'est tout un système qui se construit autour des publications pour mesurer la qualité des établissements. Or, les enseignants-chercheurs ne partagent pas les mêmes attitudes par rapport au système de publication. Nous avons élaboré une typologie afin de rendre compte de cette diversité des acteurs et de leurs stratégies d’adaptation face aux nouvelles injonctions institutionnelles. / The goal of the thesis is to understand the link between the international rankings, the publication system, and the academics in business studies. We will study their relations by using the Giddens’ theory of structuration and the concepts of habitus and field of Bourdieu. Rankings build performance indicators are usually based on articles in international journals. Rankings criterias are internalized by institutions and influence their strategy and their evaluation system. It’s a system which is built around the publications to measure the quality of institutions. However, the academics do not have the same attitude towards the publication system. We have developed a typology to reflect this diversity of agents and their adaptation strategies towards the new institutional injunctions.

Implementing Differential Privacy for Privacy Preserving Trajectory Data Publication in Large-Scale Wireless Networks

Stroud, Caleb Zachary 14 August 2018 (has links)
Wireless networks collect vast amounts of log data concerning usage of the network. This data aids in informing operational needs related to performance, maintenance, etc., but it is also useful for outside researchers in analyzing network operation and user trends. Releasing such information to these outside researchers poses a threat to privacy of users. The dueling need for utility and privacy must be addressed. This thesis studies the concept of differential privacy for fulfillment of these goals of releasing high utility data to researchers while maintaining user privacy. The focus is specifically on physical user trajectories in authentication manager log data since this is a rich type of data that is useful for trend analysis. Authentication manager log data is produced when devices connect to physical access points (APs) and trajectories are sequences of these spatiotemporal connections from one AP to another for the same device. The fulfillment of this goal is pursued with a variable length n-gram model that creates a synthetic database which can be easily ingested by researchers. We found that there are shortcomings to the algorithm chosen in specific application to the data chosen, but differential privacy itself can still be used to release sanitized datasets while maintaining utility if the data has a low sparsity. / Master of Science / Wireless internet networks store historical logs of user device interaction with it. For example, when a phone or other wireless device connects, data is stored by the Internet Service Provider (ISP) about the device, username, time, and location of connection. A database of this type of data can help researchers analyze user trends in the network, but the data contains personally identifiable information for the users. We propose and analyze an algorithm which can release this data in a high utility manner for the researchers, yet maintain user privacy. This is based on a verifiable approach to privacy called differential privacy. This algorithm is found to provide utility and privacy protection for datasets with many users compared to the size of the network.

Modern Literacy: New Media's Gift to Nonfiction, the Self, and the Community

Carlton, Tracey S. 01 January 2007 (has links)
Integrating new-media nonfiction into secondary-level English provides an efficient and effective resource in teaching modern literacy, which requires an understanding of the participatory element of communication today. Messages can be consumed and created among multimodalities and multimedia. The form and interactivity of a publication can affect its interpretation. Technology extends students' publishing capabilities and their reach to a bounty of discourse communities.This thesis, which is available in conventional hard copy and electronic forms, explores the definitions of New Media and modern literacy, how teachers can adopt the use of New Media nonfiction, and the resources needed to do so. A case study stands as a practical example. The Participatory Element Cone measures a publication's interactivity and sensory stimulation. The thesis is broken into modules, rather than chapters, so that the reader can choose to follow it linearly or to use the paper more as a manual and enter it at any point.

Systematic review and meta-analysis of experimental multiple sclerosis studies

Vesterinen, Hanna Mikaela January 2013 (has links)
Background: Multiple sclerosis (MS) is the most common cause of disability in young people and yet there are no interventions available which reliably alter disease progression. This is despite several decades of research using the most common animal model of multiple sclerosis, experimental autoimmune encephalomyelitis (EAE). There is now emerging evidence across the neurosciences to suggest that limited internal validity (measures to reduce bias) and external validity (e.g. using a clinically relevant animal model) may influence the translational success. Aim and objectives: To provide an unbiased summary of the scope of the literature on candidate drugs for MS tested in EAE to identify potential reasons for the failures to translate efficacy to clinical trials. My objectives were, across all of the identified publications, to: (1) describe the reporting of measures to reduce bias and to assess their impact on measures of drug efficacy; (2) assess the relationship between treatment related effects measured using different outcome measures; (3) assess the prevalence and impact of any publication bias; (4) compare findings from the above with another disease with limited translational success (Parkinson’s disease; PD). Methods: I used systematic searches of three online databases to identify relevant publications. Estimates of efficacy were extracted for neurobehavioural scores, inflammation, demyelination and axon loss. For PD experiments, we searched for dopamine agonists tested in animal models of PD with outcome assessed as change in neurobehavioural scores. I calculated normalised mean difference or standardised mean difference effect sizes and combined these in a meta-analysis using a random effects model. I used stratified meta-analysis or meta-regression to assess the extent to which different study design characteristics explained differences in reported efficacies. These characteristics included: measures to reduce bias (random allocation to group and blinded assessment of outcome), the animal species, sex, time of drug administration, route of drug administration and the number of animals per group. Publication bias was assessed using funnel plotting, Egger regression and “trim and fill”. Results: I identified 1464 publications reporting drugs tested in EAE. Reported study quality was poor: 11% reported random allocation to group, 17% reported blinded assessment of neurobehavioural outcomes, 28% reported blinded assessment of histological outcomes, and < 1% reported a sample size calculation. Estimates of efficacy measured as the reduction in inflammation were substantially higher in unblinded studies (47.1% reduction (95% CI 41.8-52.4)) versus blinded studies (33.1% (25.8-40.4). Moreover, the same finding was identified for 121 publications on dopamine agonists tested in experimental PD models where efficacy was measured as change in neurobehavioural outcomes. For EAE studies we were unable to include data from 631 publications describing original research. Usually this was because the publication did not include basic details such as the number of animals in each group (115 publications), the observed variance (592) or suitable control data (49). For each category of outcome I found evidence of a substantial publication bias. Interventions were most commonly administered on or before the induction of EAE with shorter times to treatment associated with higher estimates of efficacy for the reduction in mean severity scores (a neurobehavioural outcome). Treatment related effects were found to vary across different outcome measures with the largest effect being for the reduction in axon loss. Where neurobehavioural scores and axon loss were measured in the same cohort of animals, the concordance between efficacies in these increased with later times to treatment. Conclusions: In this, the largest systematic review and meta-analysis of animal studies in any domain, I have found that a large number of publications present incomplete data. In addition, measures to reduce bias are seldom reported, the lack of which is associated with overstatements of efficacy for both a measure of drug efficacy in EAE and experimental PD studies. Translational success may have also been affected by the majority of studies administering drugs on or before EAE induction which is of limited relevance in the clinical setting where patients do not present at that stage of disease. Moreover, my analysis of the relationship between outcome measures provides empirical evidence from systematically identified studies to suggest that targeting axon loss as later time points is most strongly associated with improvements in neurobehavioural scores. Therefore drugs which are successfully able to target axon loss at these time points may offer substantial hope for clinical success. Overall, improvements in the conduct and reporting of preclinical studies are likely to improve their utility, and the prospects for translational success. While my findings relate predominately to the animal modelling of MS and PD it is likely that they also hold for other animal research.

Publication and editorial feedback experiences of doctoral students in counselor education: a phenomenological inquiry

Lee, Injung 01 May 2019 (has links)
research and publishing articles in refereed journals is one of the most critical objectives of counselor education programs. Despite this, the lack of scholarly productivity among counseling scholars, including counselor educators and doctoral students, continues to be a problem in the profession. Also, research on doctoral students’ research and publication has been scarce in counseling literature. Moreover, the current literature largely fails to communicate the perspectives of doctoral students, as it reflects only the counselor educators’ perspectives on research training. This phenomenological study investigated the shared experiences of twelve doctoral students in CACREP-accredited programs, regarding research and publication, including the editorial feedback process. The research question that informed and guided this study was: What are the lived experiences of doctoral students in counselor education programs during the publication and editorial feedback process? This study specifically aimed to examine doctoral student researchers’ challenges, the support they received, critical incidents that occurred, as well as their meaning-making of those experiences during the entire process of research and publication. Data collection included two rounds of semi-structured interviews, two online focus groups, and written responses to two open-ended questions. Data analysis followed the procedures of phenomenological data reduction, including open-coding and horizonalization. Through individual case summaries and the seven themes that were derived from the twelve participants’ stories, this study illustrated how doctoral students made meaning of their experience with regard to the publication and editorial feedback process. The findings that emerged included the research climate/culture of both the counselor education profession and counselor education programs, as well as the support and resources that doctoral students received or needed. The findings also indicated doctoral students’ motivations to conduct research, and their learning experiences that contributed to their development as independent researchers. Finally, the meaning making of being a doctoral student researcher was described. Based upon these research findings, implications were provided for doctoral students, counselor educators, counselor education programs, journal editorial boards, and future research.
