A tanulmány a PPP különböző strukturális modelljeinek csoportosítását mutatja be, az egyes típusok rövid rendszerező áttekintésével. A tipológiák vizsgálata hasznos ahhoz, hogy a PPP projektek struktúrájának kialakításakor a különböző lehetőségeket mérlegelni tudjuk. Többféle megközelítésben lehet a modelleket tipizálni. Az együttműködés célja alapján a hatékonyság-, a minőség- és a finanszírozás-orientált modellek a legelterjedtebbek, a kockázatmegosztás módja alapján BOT, DBFO és koncessziós változatok, a haszonmegosztás szabályozása alapján árplafon-szabályozású, közvetlen haszonszabályozású, fixdíjas és árnyékáras megoldások a leginkább bevettek. A tanulmány ezek elemző bemutatása alapján arra a következtetésre jut, hogy a gyakorlati megoldások a legtöbb esetben az elméleti típusok valamilyen kombinációját tartalmazzák, a konkrét eset feltételeinek megfelelően. Így a gyakorlatban a fix tipológiák helyett alkalmasabb úgy megközelítenünk a PPP-t, mint egy folyamatosan változó, a helyi igényekhez idomuló jelenséget. A haszonszabályozó tipológia kapcsán a tanulmány melléklete rövid áttekintést nyújt a PPP esetében kritikus méltányos haszon becslésének lehetséges megoldásairól is. = This study shows a categorization of the different structural models of Public-Private Partnership (PPP) projects. The typologies are useful to assess the available options when decisions on PPP project structures are made. There are different categorizing aspects. Based ont he key purpose of the partnership there are efficiency, quality and financing focused models. From a risk sharing point of view, BOT, DBFO and concession models are most typical. Regarding the regulation of returns price-cap models, ’open book’ models, fixed price and shadow pricing models are most common. Based on the analytical assessment of these, they study concludes that actual projects are mostly a combination of theoretical types, as required by the given case. Therefore in practice, it is more appropriate to approach PPP projects as a constantly shaping concept, adjustable to particular conditions. Supporting the approaches to the regulation of returns, an appendix of the study summarizes the different methods to estimate fair returns, a critical issue in PPP projects.

A tanulmány a Public-Private Partnership (PPP) immanens logikai kihívásai közül két kiemelt kérdést elemez: az állami fél közszolgálati-közigazgatási beágyazottságából eredő dilemmákat, valamint az állami és a magánfél eltérő kulturális hátteréből eredő feszültségek jellemzőit. A PPP projektek gyakorlati megvalósítása szempontjából e két kardinális kérdés kifinomult elméleti hátterébe nyújt bepillantást. A közszolgáltatási dilemmák közül azonosítja és tárgyalja a jogszerűség vs. eredményesség, a hatékonyság vs. eredményesség, a centralizáció vs. decentralizáció, a közérdek vs. egyéni szabadságjogok védelme, valamint a kormányzat kicsinyítése vs. jogbiztonság védelme, és a vállalkozói szemlélet vs. közszolgálatiság közti egyensúlyozás kihívásait. Az állami és az üzleti fél kulturális különbözőségének központi motívumaként a döntéshozatalbeli különbséget ragadja meg, és a bizalom szerepét hangsúlyozza a működőképes modell megtalálásának lehetőségeként. = This study analyses two cardinal issues of Public-Private Partnership (PPP) projects’ immanent challenges: the management dilemmas of public services/governance, and the tensions between the private and public parties due to their different cultural imbeddedness. It provides theoretical insights into these two issues of practical relevance. As public service management dilemmas, it identifies the trade-offs between rights vs. effectiveness, efficiency vs. effectiveness, centralization vs. decentralization, protecting the public interest vs. individual freedom, minimizing government vs. protecting human rights, the entrepreneurial approach vs. public service ethos. The study captures the cultural difference between the public and the private parties in their different approaches to decision making, while it concludes that the role of trust is key in finding feasible solutions for PPP models.

This research will investigate what it will take to develop principals who will embrace the recommendations of reform as proposed by National Association of Secondary School Principals (NASSP, 1996) in the Breaking Ranks document. Breaking Ranks is based on the belief that it is within the dynamics of the school culture that principals must gain insight into strategies for improving the schools for which they are held responsible. Given this context, it is important to examine perspectives that are held by principals who lead schools that embrace the concepts of reform as proposed by NASSP, thereby, could be deemed “Breaking Ranks” schools. It is within these schools that the new role of the principal develops. NASSP has identified seven key recommendations for leadership development; “attributes that need nourishing” (p. 12) for the success of school reform. The seven recommendations are included in Breaking Ranks. ^ The purpose of this study is to identify and describe how principals put the seven recommendations into practice as they function in their schools. In addition, this study will gather information on the characteristics, support, skills, and training these principals identify as critical aspects and components of their success. This is a study of principal leadership at four high school sites where “Breaking Ranks” principals have been identified. ^ This research plan will be designed to utilize an inquiry-based process with a panel of experts and four “Breaking Ranks” principals. This study will describe: (1) how a panel of experts identify what they believe needs to be done in order to put the recommendations of the Breaking Ranks document into practice and their identification of principals who are breaking ranks; (2) how identified principals say they have been able to put the recommendations of the Breaking Ranks document into practice; (3) How both groups identify and describe: (a) the characteristics and behaviors of a “Breaking Ranks” principal; (b) the new leadership skills as described by the seven recommendations identified in the Breaking Ranks document; (c) the support necessary in order to meet the recommendations in the Breaking Ranks document; and (d) The training needed in order to become “Breaking Ranks” principals; and (4) how the process of creating “Breaking Ranks” principals can be described by experts who have studied it theoretically and principals who have demonstrated it in their schools. ^

This study assessed the civic knowledge, skills, and attitudes of Hispanic eighth grade students in Miami-Dade County Public Schools (M-DCPS), Florida. Three hundred sixty one Hispanic students of Cuban (253), Colombian (57), and Nicaraguan (51) ancestry from 10 middle schools participated in the study. Two hundred twenty eight students were from low socio-economic status (SES) background, and 133 were of middle SES background. There were 136 boys and 225 girls. The International Association for the Evaluation of Educational Achievement Civic Education Student Questionnaire was used to collect data. The instrument assessed the students’ civic knowledge, skills, and attitudes. Multivariate analysis of variance was used to test for differences in the civic knowledge, skills, and attitudes of participants based on ancestry, SES, and gender. ^ The findings indicated that there was no significant difference in the civic knowledge, skills, and attitudes of Hispanic eighth grade students that were of Cuban, Colombian, and Nicaraguan ancestry. There was no significant difference in the civic skills and in five of the civic attitude scales for students from low SES families compared to those from middle SES families. However, there was a significant difference in the civic knowledge and in the civic attitude concerning classroom discussions and participation based on SES. The civic knowledge of middle SES students was higher than that of low SES students. Furthermore, middle SES Hispanic students displayed a higher mean score for the civic attitude of classroom discussions and participation than low SES students. There was no significant difference in the civic knowledge and in five of the civic attitude scales between boys and girls. However, there was a significant difference in the civic skills and the civic attitude of support for women’s rights between boys and girls. Hispanic girls displayed a higher mean score in civic skills than Hispanic boys. Furthermore, the mean score of civic attitude of support for women’s rights for Hispanic girls was higher than that of Hispanic boys. ^ It was concluded that Cuban, Colombian, or Nicaraguan participants did not demonstrate differences in civic attitudes and levels of civic knowledge and skills that eighth grade students possessed. In addition, when compared to boys, girls demonstrated a higher level of civic skills and a greater support for women’s rights and participation in politics and their roles in politics. Moreover, SES was demonstrated to be a key factor in the acquisition of civic knowledge, regardless of ancestry.^

The dissertation takes a multivariate approach to answer the question of how applicant age, after controlling for other variables, affects employment success in a public organization. In addition to applicant age, there are five other categories of variables examined: organization/applicant variables describing the relationship of the applicant to the organization; organization/position variables describing the target position as it relates to the organization; episodic variables such as applicant age relative to the ages of competing applicants; economic variables relating to the salary needs of older applicants; and cognitive variables that may affect the decision maker's evaluation of the applicant. ^ An exploratory phase of research employs archival data from approximately 500 decisions made in the past three years to hire or promote applicants for positions in one public health administration organization. A logit regression model is employed to examine the probability that the variables modify the effect of applicant age on employment success. A confirmatory phase of the dissertation is a controlled experiment in which hiring decision makers from the same public organization perform a simulated hiring decision exercise to evaluate hypothetical applicants of similar qualifications but of different ages. The responses of the decision makers to a series of bipolar adjective scales add support to the cognitive component of the theoretical model of the hiring decision. A final section contains information gathered from interviews with key informants. ^ Applicant age has tended to have a curvilinear relationship with employment success. For some positions, the mean age of the applicants most likely to succeed varies with the values of the five groups of moderating variables. The research contributes not only to the practice of public personnel administration, but is useful in examining larger public policy issues associated with an aging workforce. ^

The study of the private management of public housing is an important topic to be critically analyzed as the government search for ways to increase efficiency in providing housing for the poor. Public Housing Authorities must address the cost for repairing or replacing the deteriorating housing stock, the increase in the need for affordable housing, and the lack of supply. There is growing pressure on efficient use of public funds that has heightened the need for profound structural reform. An important strategy for carrying out such reform is through privatization. Although privatization does not work in every case, the majority position in the traditional privatization literature is that reliance on private organizations normally, but not always, results in cost savings. ^ The primary purpose of this dissertation is to determine whether a consensus exist among decision-makers on the efficiency of privatizing the management of public housing. A secondary purpose is to review the techniques (best practices) used by the private sector that results in cost-efficiencies in the management of public housing. The study employs the use of a triangulated research design utilizing cross-sectional survey methodology that included use of a survey instrument to solicit responses from the private managers. The study consists of qualitative methods using interviews from key informants of private-sector management firms and public housing agencies, case studies, focus groups, archival records and housing authorities documents. ^ Results indicated that important decision-makers perceive that private managers made a positive contribution to cost-efficiencies in the management of public housing. The performance of private contractors served as a yardstick for comparison of efficiency of services that are produced in-house. The study concluded that private managers made the benefits of their management techniques well known creating a sense of competition between public and private managers. Competition from private contractors spurred municipal worker and management productivity improvements creating better management results for the public housing authorities. The study results are in concert with a review of recent research and studies that also concluded private managers have some distinct advantages to controlling costs in the management of public housing. ^

The purpose of this study was to examine the relationship between the structure of jobs and burnout, and to assess to what extent, if any this relationship was moderated by individual coping methods. This study was supported by the Karasek's (1998) Job Demand-Control-Support theory of work stress as well as Maslach and Leiter's (1993) theory of burnout. Coping was examined as a moderator based on the conceptualization of Lazarus and Folkman (1984). ^ Two overall overarching questions framed this study: (a) what is the relationship between job structure, as operationalized by job title, and burnout across different occupations in support services in a large municipal school district? and (b) To what extent do individual differences in coping methods moderate this relationship? ^ This study was a cross-sectional study of county public school bus drivers, bus aides, mechanics, and clerical workers (N = 253) at three bus depot locations within the same district using validated survey instruments for data collection. Hypotheses were tested using simultaneous regression analyses. ^ Findings indicated that there were statistically significant and relevant relationships among the variables of interest; job demands, job control, burnout, and ways of coping. There was a relationship between job title and physical job demands. There was no evidence to support a relationship between job title and psychological demands. Furthermore, there was a relationship between physical demands, emotional exhaustion and personal accomplishment; key indicators of burnout. ^ Results showed significant correlations between individual ways of coping as a moderator between job structure, operationalized by job title, and individual employee burnout adding empirical evidence to the occupational stress literature. Based on the findings, there are implications for theory, research, and practice. For theory and research, the findings suggest the importance of incorporating transactional models in the study of occupational stress. In the area of practice, the findings highlight the importance of enriching jobs, increasing job control, and providing individual-level training related to stress reduction.^

Where the public acceptability of a policy can influence its chance of success, it is important to anticipate and mitigate potential concerns. This paper applies search frequency analysis and a form of claims-making analysis to identify public acceptability concerns among fourteen policies proposed by the EU-funded DYNAMIX project to achieve EU resource efficiency. Key points of contention in the corresponding public discourses focus primarily on trust, fairness, effectiveness and cost. We use our findings to provide specific recommendations for the design and implementation of the proposed policy mix which are intended to improve the public acceptability of contentious aspects, and highlight some broader insights for policymakers.

Abstract This thesis examines one of the most sensitive challenges facing contemporary democracies: the accommodation of Muslim minorities in public institutions and services. It focuses on the field of education, and on two particular issues: the public funding of Islamic schools and the accommodation of Muslim needs in public secular schools. The analysis is based on an examination of outcomes in four jurisdictions that differ significantly in the level of accommodation that has emerged: England, Scotland, Ontario, and Quebec. I seek to explain why such variation in outcomes exists among these four cases. I draw on four bodies of literature to underpin the theoretical framework: historical institutionalism, political mobilization by civil society, political parties, and ideationalism. My argument can be summarized simply; historic church-state settlements, unique in each case, are the most important factor explaining the variation in outcomes in England, Scotland, Ontario, and Quebec. In some cases, the historic church-state template is incrementally adapted to accommodate Muslim minorities. In other cases, relatively little accommodation occurs and the path-dependent trajectory of church-state relations remains entrenched. While the historic church-state template is a necessary factor in the explanation, it does not fully account for the variation. For a more complete picture, I demonstrate that there are several additional key factors that also shape the outcomes: first, national identity and public attitudes towards immigration and immigrants; second, the extent of mobilization by political agents, such as civil society organizations and historic churches; and third, the response of political parties to demands by Muslims for institutional accommodation. Ultimately, I conclude that Muslims in these jurisdictions are receiving some accommodation, but the process is slow and partial. This thesis makes important theoretical and empirical contributions to the discussion of Muslim integration in liberal democratic states. First, a framework has yet to be developed that considers the theoretical implications of institutional accommodation of Muslims; I address this gap. Second, this research demonstrates the utility of historical institutionalism in explaining the adaptation of church-state templates to accommodate Muslims’ demands. Last, this study makes an original contribution by comparing the cases of England, Scotland, Ontario, and Quebec in the accommodation of Muslims in education. A comparison of Canada with the United Kingdom has not yet been done.

There has been a debate for years about what the role of the ombudsman is. This article examines a key component of the role, to promote trust in public services and government. To be able to do this, however, an ombudsman needs to be perceived as legitimate and be trusted by a range of stakeholders, including the user. This article argues that three key relationships in a person’s complaint journey can build trust in an institution, and must therefore be understood as a system. The restorative justice framework is adapted to conceptualize this trust model as a novel approach to understanding the institution from the perspective of its users. Taking two public sector ombudsmen as examples, the article finds that voice and trust need to be reinforced through the relationships in a consumer journey to manage individual expectations, prevent disengagement, and thereby promote trust in the institution, in public service providers, and in government.

In January 2014, the Northern Ireland Policing Board (NIPB) commissioned the University of Ulster to conduct research into public confidence in policing to help inform the work of the Board and its oversight of police service delivery. More specifically, the research team were tasked with exploring ‘the key drivers of confidence in Northern Ireland’. To date, the subject of ‘confidence in policing’ within a Northern Ireland context has been relatively under researched, both in academic and policy terms. Thus, the present research is the first empirical research to be produced in the country to empirically assess confidence in policing from a cross section of society – including the key dynamics and drivers that underpin police confidence at a community level.

The report begins with a comprehensive review of academic literature, policy documents and contemporary events related to confidence in policing. The research then provides an overview of the methodology used to undertake the research, with the remainder of the report comprised of the findings from the survey. The report concludes with an overview of the central findings along with a series of recommendations.
