Is the physical availability of alcohol and illicit drugs related to neighborhood rates of child maltreatment?

OBJECTIVE: This study examines how the availability of alcohol and illicit drugs (as measured by alcohol outlet density and police incidents of drug sales and possessions) is related to neighborhood rates of child abuse and neglect, controlling for other neighborhood demographic characteristics. METHOD: Data from substantiated reports of child abuse and neglect in 304 block groups in a northern California city were analyzed using spatial regression techniques. RESULTS: This study found that higher concentration of bars (B=6.66, p<.05) and higher numbers of incidents of drug possession (B=.53, p<.001) were positively related to rates of child maltreatment in neighborhoods when controlling for neighborhood demographic characteristics. Thus, areas with more bars and drug possession incidents per 1000 population have higher rates of child maltreatment. CONCLUSIONS: The presence of more bars per population may represent a lack of resources available to residents, may increase the stress on neighborhoods by "attracting" populations prone to participating in dangerous activities, or increase the frequency of alcohol use that then leads to maltreatment. Areas with more drug possession incidents may also contribute to the overall level of neighborhood stress and disorganization or act as a marker for drug use that leads to maltreatment. These results suggest that the neighborhood substance availability may deserve special attention when developing preventive interventions to reduce child abuse and neglect in neighborhood areas.     

Graded hypoxia and blood oxidative stress during exercise recovery

Altitude exposure and exercise elicit oxidative stress in blood; however, exercise recovery at 5000 m attenuates oxidative stress. The purpose was to determine the altitude threshold at which blood oxidative stress is blunted during exercise recovery. Twelve males 18–28 years performed four-cycle ergometry bouts (60 min, 70% VO_2max, at 975 m). In a randomised counterbalanced crossover design, participants recovered 6 h at 0, 1667, 3333 and 5000 m in a normobaric hypoxia chamber (recovery altitudes were simulated by using a computerised system in an environmental chamber by lowering the partial pressure of oxygen to match that of the respective altitude). Oxygen saturation was monitored throughout exercise recovery. Blood samples obtained pre-, post-, 1 h post- and 5 h post-exercise were assayed for ferric-reducing antioxidant plasma, Trolox equivalent antioxidant capacity, uric acid, lipid hydroperoxides and protein carbonyls. Muscle biopsies obtained pre and 6 h were analysed by real-time polymerase chain reaction to quantify expression of hemeoxgenase 1, superoxide dismutase 2 and nuclear factor (euthyroid-derived 2)-like factor. Pulse oximetry data were similar during exercise, but decreased for the three highest recovery elevations (0 m = 0%, 1667 m = ?3%; 3333 m = ?7%; 5000 m = ?17%). A time-dependent oxidative stress occurred following exercise for all variables, but the two highest recovery altitudes partially attenuated the lipid hydroperoxide response (0 m = +135%, 1667 m = +251%, 3333 m = +99%; 5000 m = +108%). Data may indicate an altitude threshold between 1667 and 3333 m, above which the oxidative stress response is blunted during exercise recovery.     

Serving multiple stakeholders: Issues arising from a major national evaluation study

This paper provides an analysis of the issues arising from work with multiple stakeholders within the context of a major national evaluation study. The context is the UK Education Departments' Superhighways Initiative (EDSI), which was jointly funded by the four education departments of England, Wales, Scotland and Northern Ireland. Unusually, the evaluation, which was large scale and employed several teams of evaluators, had a real opportunity to inform the development of policy. Problems of working for multiple stakeholders arose from the tight control that the sponsors exercised over the structure, style and content of the report. In addition to the usual problems of conflicting interests between stakeholders, the Scottish evaluators experienced problems relating to the polarised political context in the UK prior to the general election of 1997. The successful public relations exercise that created the EDSI programme, with commercial sponsorship for projects and government funding only for the evaluation, was an additional factor in determining the evaluators' roles and relationships with stakeholders.     

What helps and hinders indigenous student success in higher education health programmes: a qualitative study using the Critical Incident Technique

Tertiary institutions aim to provide high quality teaching and learning that meet the academic needs for an increasingly diverse student body including indigenous students. Tātou Tātou is a qualitative research project utilising Kaupapa Ma¯ori research methodology and the Critical Incident Technique interview method to investigate the teaching and learning practices that help or hinder Ma¯ori student success in non-lecture settings within undergraduate health programmes at the University of Auckland. Forty-one interviews were completed from medicine, health sciences, nursing and pharmacy. A total of 1346 critical incidents were identified with 67% helping and 33% hindering Ma¯ori student success. Thirteen sub-themes were grouped into three overarching themes representing potential areas of focus for tertiary institutional undergraduate health programme development: Māori student support services, undergraduate programme, and Ma¯ori student whanaungatanga. Academic success for indigenous students requires multi-faceted, inclusive, culturally responsive and engaging teaching and learning approaches delivered by educators and student support staff.     

Perception and use of reinforcement by special education teachers

This study aimed to investigate whether special education teachers shared similar difficulties in their understanding of reward and punishment as their mainstream peers. Thirty‐five teachers working in six special education needs schools took part in a mixed methods study to explore their use and understanding of reinforcement principles. The purpose of the mixed methods approach was to triangulate the teachers use and perceived use of different reinforcement strategies within the classroom. Teachers’ had a good grasp of positive reward‐based strategies, but their understanding of the other three types of reinforcement (negative reward, punishment and penalty) was less accurate. There was a clear aversion amongst the sample to discuss punishment with many stating that they do not use it, which contrasted with the observations. Structured continued professional development interventions are required to rectify the discrepancies between belief and evidence.     

Value Conflicts in the Management of Innovation: supporting information technology innovation in initial teacher training in the United Kingdom

ABSTRACT

This paper is concerned with the process of innovation at both the institutional and personal‐professional levels. The focus is on the practical and moral dilemmas of managing innovation in the context of coercive policies imposed from outside. Innovation is defined as any activity or practice which involves human beings in changes to established routines. It is always embedded in a unique, multi‐level context. Qualitative methods are used to examine the case of five institutions in the UK working within a funded project to introduce more effective use of information technology in initial teacher education. The aim of the paper is to use the case to generate theories which, although they cannot be generalised to other contexts, can inform the thinking of those responsible for the management of innovation in other institutions.     

Teaching the teacher: exploring STEM graduate students’ nature of science conceptions in a teaching methods course

ABSTRACT

Graduate students regularly teach undergraduate STEM courses and can positively impact students’ understanding of science. Yet little research examines graduate students’ knowledge about nature of science (NOS) or instructional strategies for teaching graduate students about NOS. This exploratory study sought to understand how a 1-credit Teaching in Higher Education course that utilised an explicit, reflective, and mixed-context approach to NOS instruction impacted STEM graduate students’ NOS conceptions and teaching intentions. Participants included 13 graduate students. Data sources included the Views of Nature of Science (VNOS-Form C) questionnaire administered pre- and post-instruction, semi-structured interviews with a subset of participants, and a NOS-related course project. Prior to instruction participants held many alternative NOS conceptions. Post-instruction, participants’ NOS conceptions improved substantially, particularly in their understandings of theories and laws and the tentative nature of scientific knowledge. All 12 participants planning to teach NOS intended to use explicit instructional approaches. A majority of participants also integrated novel ideas to their intended NOS instruction. These results suggest that a teaching methods course for graduate students with embedded NOS instruction can address alternative NOS conceptions and facilitate intended use of effective NOS instruction. Future research understanding graduate students' NOS understandings and actual NOS instruction is warranted.     

Prekindergarten Interactive Book Reading Quality and Children’s Language and Literacy Development: Classroom Organization as a Moderator

Research Findings: This study examined the association between interactive book reading quality and prekindergarten children’s gains in language and literacy skills over the course of an academic year for 96 teachers and 417 children across multiple locations in the United States. Two moderators were examined, namely, children’s initial skill level and teachers’ classroom organization during an interactive read-aloud session. In keeping with prior research, interactive book reading quality, measured by examination of teachers’ extratextual talk, was positively and significantly related to children’s development of both language and literacy skills. Interactive book reading quality was not significantly moderated by children’s initial skills, with the exception that interactive book reading quality appeared most beneficial to children’s print knowledge for children entering prekindergarten with relatively low skill. The unique contribution of this study is that the association between interactive book reading quality and children’s expressive vocabulary was dependent on an organized classroom during the book reading session. Practice or Policy: The quality of teachers’ talk during interactive book reading may matter for children’s vocabulary development only when reading sessions are characterized by relatively high classroom organization. Classroom organization should be an important consideration while planning for interactive book reading sessions.
