Treatment Decisions Involving Teeth with Intrapulpal Cracks: A Survey of Endodontists
There is no universal protocol for diagnosing, treating and managing cracked teeth. The purpose of this survey was to investigate the use of traditional methods of crack detection and to explore how treatment decisions were made using an intrapulpal crack classification. The electronic survey was sent to 1115 active members of the American Association of Endodontists (AAE) and The Digital Office (TDOâ„¢) community. Comparisons were assessed using logistic or repeated-measures regression. The most often used diagnostic method was probing. When the crack involved one wall, 85% of respondents would complete root canal therapy \u3e 50% of the time or always. For two or more walls, the percentage dropped to 44%. When the crack involved the floor or orifices, 60% would not complete treatment. For necrotic teeth, 36% of respondents preferred extraction as opposed to 3% if vital. This survey illustrated the anecdotal nature of detection, diagnosis and management of cracked teeth
Observations of QSO J2233-606 in the Southern Hubble Deep Field
The Hubble Deep Field South (HDF-S) HST observations are expected to begin in
October 1998. We present a composite spectrum of the QSO in the HDF-S field
covering UV/optical/near IR wavelengths, obtained by combining data from the
ANU 2.3m Telescope with STIS on the HST. This intermediate resolution spectrum
covers the range 1600-10000A and allows us to derive some basic information on
the intervening absorption systems which will be important in planning future
higher resolution studies of this QSO.Comment: 9 pages and 2 figures, submitted to ApJ

A scoping review of bereavement risk assessment measures: Implications for palliative care
© The Author(s) 2015. Background: Palliative care standards and policies recommend that bereavement support be provided to family caregivers, yet uncertainty surrounds whether support currently offered by palliative care services throughout developed countries meets caregiver needs. The public health model of bereavement support, which aligns bereavement support needs with intervention, may address this gap between policy and practice. Aim: The aim was to review the literature to identify bereavement risk assessment measures appropriate for different points in the caring and bereavement trajectories, evaluate their psychometric properties and assess feasibility for use in palliative care. Design: A scoping review was systematically undertaken following Arksey and O'Malley's methodological framework. Data sources: PsycINFO, CINAHL, PubMed and Cochrane Reviews databases, as well as grey literature including Internet searches of Google, World Health Organization, CareSearch, the Grey Literature Report and OAIster were searched. Bereavement organisations and palliative care websites, reference lists in obtained articles and grief and bereavement handbooks were also scrutinised. Results: Of 3142 records screened, 356 records yielded 70 grief measures. In all, 19 measures published between 1982 and 2014 were identified for inclusion in this review, and categorised for use with family caregivers at three points in time - before the patient's death (n = 5), in the period following the death (n = 10) and for screening of prolonged or complex grief (n = 4). The majority had acceptable psychometric properties; feasibility for use in palliative care varied substantially. Conclusion: This review is an important preliminary step in improving the assessment of bereavement risk and, consequently, better bereavement outcomes for palliative care family caregivers
Team sport athletes’ perceptions and use of recovery strategies: a mixed-methods survey study
Background:
A variety of recovery strategies are used by athletes, although there is currently no research that investigates perceptions and usage of recovery by different competition levels of team sport athletes.
Methods:
The recovery techniques used by team sport athletes of different competition levels was investigated by survey. Specifically this study investigated if, when, why and how the following recovery strategies were used: active land-based recovery (ALB), active water-based recovery (AWB), stretching (STR), cold water immersion (CWI) and contrast water therapy (CWT).
Results:
Three hundred and thirty-one athletes were surveyed. Fifty-seven percent were found to utilise one or more recovery strategies. Stretching was rated the most effective recovery strategy (4.4/5) with ALB considered the least effective by its users (3.6/5). The water immersion strategies were considered effective/ineffective mainly due to psychological reasons; in contrast STR and ALB were considered to be effective/ineffective mainly due to physical reasons.
Conclusions:
This study demonstrates that athletes may not be aware of the specific effects that a recovery strategy has upon their physical recovery and thus athlete and coach recovery education is encouraged. This study also provides new information on the prevalence of different recovery strategies and contextual information that may be useful to inform best practice among coaches and athletes

Comparison of grouper assemblages in northern areas of the wider Caribbean: A preliminary assessment
Groupers (Pisces: Serranidae) are important top-level predators in wider Caribbean, but have experienced significant exploitation, resulting in declines in abundance, size, spawning aggregations, and changes in species composition. Larger groupers are particularly vulnerable to intense fishing because of their longevity, slow growth, delayed reproduction, and aggregate spawning. Marine fishery reserves (MFR), areas permanently closed to consumptive use, offer a viable means to protect grouper resources. This study reports on fishery-independent surveys of groupers in four regions of the tropical western Atlantic during 1995 - 1997: Florida Keys, central Bahamas, southeastern Cuba, and Dominican Republic. The regions surveyed included two national parks and a national marine sanctuay, and were further categorized as: 1) intensively fished with little or no management for groupers (Cuba, Dominican Republic); 2) intensively fished with gear and effort limitations (Florida Keys); 3) lightly fished with some management (N. and S. Exuma Cays, Bahamas); and 4) a. MFR closed to fishing since 1986 (Exuma Cays Land and Sea Park, Bahamas). From 10 - 20 strip transects (20 m x 5 m) were surveyed in shallow-water (l-20 m depth) hard-bottom habitats for grouper species composition, density, and size distribution. Nine grouper species (6 Epinephelus spp., 3 Mycteroperca spp.) were documented among all regions. Areas in which groupers were partially or wholly protected from fishing had greater grouper diversity, density, and biomass, particularly for targeted species such as Nassau grouper (E. striatus). Classification of groupers by three size classes (small, intermediate, large) indicated a distinct gradient from areas with intense fishing to the MFR. In three of the regions affected by intense fishing, one of which has several grouper fishery regulations, grouper abundance and biomass were dominated by non-targeted species such as the graysby (E. cruentatus) and coney (E. fulvus). This second-order effect of fishing probably indicates competitive or predation. MFRs represent a viable means to protect grouper resources, alleviating the complications of enforcement and partially the need to gather fisheries dependent data. The ability of groupers to recover in certain regions may be deterred because of reduced larval recruitment from upstream, heavily fished sources
Being an English academic:a social domains account
This paper considers the differential placements of social actors in the contemporary English university, as practices consistent with neoliberal ideologies become increasingly influential. It uses Layder's theory of ‘social domains’ and the first-hand experiences of the author to explore how the options available–to students, those on precarious conditions of employment, and those occupying more influential roles in the institution–change in relation to alterations in structured social relations. Examples are provided of interventions by people opposed to both the rhetoric and the reality of developments in the sector, and reasons for their limited effectiveness are also discussed
