A systematic review and meta-analysis of the survival of feldspathic porcelain veneers over 5 and 10 years

PURPOSE: This systematic review reports on the survival of feldspathic porcelain veneers.

MATERIALS AND METHODS: The Cochrane Library, MEDLINE (OVID), Embase, Web of Knowledge, selected journals, clinical trials registers, and conference proceedings were searched independently by two reviewers. Academic colleagues were also contacted to identify relevant research. Inclusion criteria were human cohort studies (prospective and retrospective) and controlled trials assessing outcomes of feldspathic porcelain veneers in more than 15 patients and with at least some of the veneers in situ for 5 years. Of 4,294 articles identified, 116 studies underwent full-text screenings and 69 were further reviewed for eligibility. Of these, 11 were included in the qualitative analysis and 6 (5 cohorts) were included in meta-analyses. Estimated cumulative survival and standard error for each study were assessed and used for meta-, sensitivity, and post hoc analyses. The I2 statistic and the Cochran Q test and its associated P value were used to evaluate statistical heterogeneity, with a random-effects meta-analysis used when the P value for heterogeneity was less than .1. Galbraith, forest, and funnel plots explored heterogeneity, publication patterns, and small study biases.

RESULTS: The estimated cumulative survival for feldspathic porcelain veneers was 95.7% (95% confidence interval [CI]: 92.9% to 98.4%) at 5 years and ranged from 64% to 95% at 10 years across three studies. A post hoc meta-analysis indicated that the 10-year best estimate may approach 95.6% (95% CI: 93.8% to 97.5%). High levels of statistical heterogeneity were found.

CONCLUSIONS: When bonded to enamel substrate, feldspathic porcelain veneers have a very high 10-year survival rate that may approach 95%. Clinical heterogeneity is associated with differences in reported survival rates. Use of clinically relevant survival definitions and careful reporting of tooth characteristics, censorship, clustering, and precise results in future research would improve metaanalytic estimates and aid treatment decisions.

Exploring inequities in child welfare and child protection services: Explaining the ‘inverse intervention law’

Attempts to record, understand and respond to variations in child welfare and protection reporting, service patterns and outcomes are international, numerous and longstanding. Reframing such variations as an issue of inequity between children and between families opens the way to a new approach to explaining the profound difference in intervention rates between and within countries and administrative districts. Recent accounts of variation have frequently been based on the idea that there is a binary division between bias and risk (or need). Here we propose seeing supply (bias) and demand (risk) factors as two aspects of a single system, both framed, in part, by social structures. A recent finding from a study of intervention rates in England, the 'inverse intervention law', is used to illustrate the complex ways in which a range of factors interact to produce intervention rates. In turn, this analysis raises profound moral, policy, practice and research questions about current child welfare and child protection services.

Quantitative regulation of FLC via coordinated transcriptional initiation and elongation

The basis of quantitative regulation of gene expression is still poorly understood. In Arabidopsis thaliana, quantitative variation in expression of FLOWERING LOCUS C (FLC) influences the timing of flowering. In ambient temperatures, FLC expression is quantitatively modulated by a chromatin silencing mechanism involving alternative polyadenylation of antisense transcripts. Investigation of this mechanism unexpectedly showed that RNA polymerase II (Pol II) occupancy changes at FLC did not reflect RNA fold changes. Mathematical modeling of these transcriptional dynamics predicted a tight coordination of transcriptional initiation and elongation. This prediction was validated by detailed measurements of total and chromatin-bound FLC intronic RNA, a methodology appropriate for analyzing elongation rate changes in a range of organisms. Transcription initiation was found to vary ∼ 25-fold with elongation rate varying ∼ 8- to 12-fold. Premature sense transcript termination contributed very little to expression differences. This quantitative variation in transcription was coincident with variation in H3K36me3 and H3K4me2 over the FLC gene body. We propose different chromatin states coordinately influence transcriptional initiation and elongation rates and that this coordination is likely to be a general feature of quantitative gene regulation in a chromatin context.

Mysis salemaai in Ireland: new occurrences and existing population declines

We report two new occurrences of Mysis salemaai, a conservationally important glacial relict at the southern limit of its range, in Castlewellan Lake and Lough Scolban, in the North of Ireland. This increases the number of lakes in Ireland where the species has been recorded to thirteen. We consider lake area and maximum lake depth as factors that might determine the long-term survival of M. salemaai populations and show that these populations tend to occur in relatively large, deep, lakes. We also show that population densities in Lough Neagh and Lough Erne are declining.

A prospective comparative evaluation of a Criminal Justice Liaison and Diversion Service in Belfast

There is continued interest in the planning, development and implementation of services designed to identify, detainees with mental illness and connect them to health and social services. However, currently little is known about how best to configure, organise and deliver these services. The study employed a prospective follow-up design with a comparator group to describe and evaluate a police mental health liaison service based in Belfast. Participants were recruited from two neighbouring police stations, only one of which provided a mental health liaison service. Outcomes including mental health status, drug and alcohol misuse, risk-related behaviour and ‘administrative’ outcomes were assessed at the time of arrest and six months later. The service was successful in identifying and assessing detainees though there appeared to be similar between-group levels of mental health problems over time. Results highlight a need to develop firmer linkages and pathways between criminal justice liaison / diversion services and routine health and social services. 

Bycatch and discards of commercial trawl fisheries in the south coast of Portugal

Bycatch and discards are a cause of great concern in commercial world fisheries, with important ecological, economic and conservation implications. With the recent inclusion of a discards ban (‘landing obligation’), in the reform of the EU CFP, these issues have gained a tremendous attention from the economic, scientific, political and social point of view. Demersal trawl fisheries off the southern coast of Portugal capture an extraordinary diversity of species and generate considerable amounts of bycatch and discards. Bycatch includes commercially valuable target-species and bycatch species with low or no commercial value, but the great majority consists of unmarketable species, that are discarded. Bony fishes are dominant in bycatch and discards and the most discarded are of low or no commercial value. The reasons for discarding are fundamentally economic in nature (lack of commercial value) for bycatch species, and legal and administrative (legal minimum landing size) for commercially important species. The study of the reproductive biology of Galeus melastomus, discarded by crustacean trawls, suggests that a minimum landing size should be established for this species, and explains the importance of such a study in the assessment and management of fisheries. The discovery of a new species of the ray Neoraja iberica n. sp. contributes to the knowledge of the local marine biodiversity in Portuguese waters and of the global marine biodiversity. The three cases of abnormal hermaphroditism recorded in Etmopterus spinax, are the first cases known to date of hermaphroditism in this species. There is a need to find solutions to the problem of bycatch and discards of trawl fisheries in the Algarve coast. A combination of technical, regulatory and economic measures to minimize bycatch and reduce discards, before implementing a ‘landing obligation’, is thought to be the best approach to apply in the southern Portuguese multispecies trawl fisheries.

The "Eco" and "Low-carbon" promise: a critical review of China's experience

The scale and speed of China’s urbanization translate into major challenges for sustainability. Could the ‘eco-city’ and ‘low-carbon’ agendas, and the promotion of related pilot cities drive Chinese urban practice towards more environmentally sustainable solutions? We explore this question through a critical review of experience in China, identifying problems relating to the development of space, the treatment of scale and the pursuit of efficiency (the ‘space-scale-efficiency nexus’). China seeks sustainable solutions through eco and low-carbon agendas, but our review finds that current efforts fall short of expectations, and problematic patterns are repeated. We propose that a geo-administrative notion of functional regions could provide a strategic framework to address the range of design, physical and administrative planning problems, ensuring that eco-city and low-carbon city pilots result in comprehensive solutions that can be effectively replicated.

From dispersed to monopolized violence: expansion and consolidation of the Primeiro Comando da Capital's hegemony in São Paulo's prisons

The present work aims to understand the process of expansion and consolidation of the organized criminal group the Primeiro Comando da Capital (PCC) in São Paulo’s prison system over the past 20 years, and the social configuration that has formed as a result of the PCCs monopolization of opportunities of power. To this end, the work of Norbert Elias is utilized to analyze empirical data collected from various sources. The article consists of two lines of analysis. First, the PCC phenomenon is approached from a macro-sociological point of view, focusing on the social, political and administrative problems that are directly or indirectly linked to the PCCs social development. Second, a figurational analysis is used to explore the social dynamics produced from this process. In comparison to the “pre-PCC” situation, it is shown that the new social configuration produced from the hegemony of the PCC consists of a complexity of interdependencies, including greater functional division and social integration. Given this intensification of mutual dependencies, the social controls on individual behavior have been expanded and centralized. Here, the structure and organization of the PCC, its political dynamics, and individual self-control are central issues. The article concludes by calling into question the view that the most significant effect of the PCCs consolidation has been social pacification of São Paulo’s prison system. Fragilities in the power of the PCC are explored, principally the precarious nature of the relationship between the PCC and state authorities, and the extent to which the PCC’s authority is imposed.

Transition into the teaching profession: induction and mentoring issues surrounding secondary music teachers /

The purpose of this study was to investigate the issues surrounding the transition into the teaching profession by specifically focusing on teacher induction and mentoring issues while explicitly addressing matters of concern by secondary music teachers in a large suburban school board in southern Ontario. Participants included beginning teachers with fewer than 5 years of teaching, mid career teachers with between 6 and 15 years of instruction, and experienced teachers with more than 16 years of practice. The ' processes of mentoring and inducting new teachers within the board were examined, along with their relationships between proteges, mentors, and administrators. Further, internal and external programs specifically designed and implemented for newer music teachers were scrutinized and discussed. An analysis of key documents and literature on the subject was performed, and data were collected through 16 personal interviews. The findings suggest that although the necessity of mentoring and induction processes has begun to be recognized, there exists a fundamental relationship between mentoring and induction and the effect of the professional attachments to mentoring; the institutional and administrative supports that are enabled; and essential processes and practices between mentors and proteges. Together these three arms combine to support successfiil induction and mentoring initiatives that will help ease the transition into teaching.

Openness and privacy in Ontario: an evaluation of the implementation of FIPPA : (The Freedom of Information and Protection of Privacy Act, 1987, Chapter 25 and Ontario Regulation 532/87) /

Since the early 1970's, Canadians have expressed many concerns about the growth of government and its impact on their daily lives. The public has requested increased access to government documents and improved protection of the personal information which is held in government files and data banks. At the same time, both academics and practitioners in the field of public administration have become more interested in the values that public servants bring to their decisions and recommendations. Certain administrative values, such as accountability and integrity, have taken on greater relative importance. The purpose of this thesis is to examine the implementation of Ontario's access and privacy law. It centres on the question of whether or not the Freedom of Information and Protection of Privacy Act, 1987, (FIPPA) has answered the demand for open access to government while at the same time protecting the personal privacy of individual citizens. It also assesses the extent to which this relatively new piece of legislation has made a difference to the people of Ontario. The thesis presents an overview of the issues of freedom of information and protection of privacy in Ontario. It begins with the evolution of the legislation and a description of the law itself. It focuses on the structures and processes which have been established to meet the procedural and administrative demands of the Act. These structures and processes are evaluated in two ways. First, the thesis evaluates how open the Ontario government has become and, second, it determines how Ill carefully the privacy rights of individuals are safeguarded. An analytical framework of administrative values is used to evaluate the overall performance of the government in these two areas. The conclusion is drawn that, overall, the Ontario government has effectively implemented the Freedom of Information and Protection of Privacy Act, particularly by providing access to most government-held documents. The protection of individual privacy has proved to be not only more difficult to achieve, but more difficult to evaluate. However, the administrative culture of the Ontario bureaucracy is shown to be committed to ensuring that the access and privacy rights of citizens are respected.

Trade Liberalization and the Profitability of Domestic Mergers.

It is often thought that a tariff reduction, by opening up the domestic market to foreign firms, should lessen the need for a policy aimed at discouraging domestic mergers. This implicitly assumes that the tariff in question is sufficiently high to prevent foreign firms from selling in the domestic market. However, not all tariffs are prohibitive, so that foreign firms may be present in the domestic market before it is abolished. Furthermore, even if the tariff is prohibitive, a merger of domestic firms may render it nonprohibitive, thus inviting foreign firms to penetrate the domestic market. In this paper, we show, using a simple example, that in the latter two cases, abolishing the tariff may in fact make the domestic merger more profitable. Hence, trade liberalization will not necessarily reduce the profitability of domestic mergers.

Le processus d'adhésion à l'Union Européenne est-il en mesure de contribuer davantage que la Convention européenne à la protection des droits de l'homme en Turquie?

La Turquie va-t-elle adhérer à l'Union européenne? Sa candidature a toujours été sujette à critiques: droits de l'homme non respectés, restrictions des droits et libertés, notamment de la liberté d'expression, de religion et des droits politiques. Les dossiers sensibles comme le problème kurde et la question chypriote sont à l'origine des multiples plaintes contre l'État turc devant la Cour européenne des droits de l'homme. Dotée des caractéristiques essentielles d'un État moderne et laïque, le pays dispose de structures formellement démocratiques, mais sa démocratie se révèle fragile: ses politiques tant internes qu'externes sont décidées par un Conseil national de sécurité composé pour l'essentiel de militaires. En outre, l'armée qui a pris le pouvoir à maintes reprises a donné au régime une dimension autoritaire. Cela non seulement en vertu des principes fondateurs de la République (tradition centralisatrice de l'État turc), mais aussi de la priorité que l'institution militaire accorde à la sécurité, à l'unité et à l'identité nationales. En effet, les mesures d'exception (état d'urgence, cours de sûreté de l'État, loi anti-terroriste) ont contribué aux violations des droits de l'homme, d'où l'opposition entre le droit conventionnel et le droit national. De plus, le système judiciaire et administratif instauré par les militaires en 1982 n'est pas conçu dans l'intérêt des justiciables. Certes, l'accès à la modernité n'a pu se faire que sous la contrainte et le contrôle de l'armée, mais le régime en Turquie peut-il continuer à s'appuyer sur les«piliers de l'ordre» que sont l'armée, la police et la justice ? L’État semble cependant se réorganiser progressivement pour permettre au pouvoir politique d'assurer un contrôleur les forces de sécurité et pour donner une meilleure indépendance à la justice. Le processus mis en route et les critères imposés pour l'adhésion à l'UE devraient contribuer à mettre en œuvre les réformes institutionnelles capables d'harmoniser la démocratie à l'État de droit, à l'image des pays européens. En effet, les changements récents sont liés à l'agenda européen. Le gouvernement turc semble être déterminé et ambitieux dans sa vocation européenne. Les progrès réalisés pour intégrer l'UE lui sont un moteur de propulsion devant servir au pays et à sa population.
