Family Involvement, Clinician Beliefs and Child Psychiatric Rehospitalization

Psychiatric rehospitalization is estimated to fall between 30% and 50% among children and adolescents and is said to be the result of complex relationships between clinical and non-clinical child, family and service system factors. Psychiatric rehospitalization has been noted as an unfavorable outcome of inpatient treatment because of the associated economic to society and the family and emotional costs to the family and patient. Therefore, several attempts have been made in the relevant literature to identify and understand factors that will reduce the risk of rehospitalization in this population. In the context of parent professional collaboration, clinician beliefs and family involvement have been indicated as important aspects of treatment among children and youth. To better understand how clinician beliefs and family involvement in treatment influence psychiatric rehospitalization, a prospective study was conducted across four phases on the child and adolescent inpatient units at a large psychiatric facility in Southern California. Data was collected from parents (N=167) of hospitalized children (ages 8-13) and adolescents (ages 14-17) and from a multidisciplinary psychiatric clinical team (N=27). Study findings indicated that neither clinician beliefs nor parent participation in inpatient activities significantly predicted psychiatric rehospitalization. Parent perceptions of empowering behaviors on the part of clinicians, previous hospitalization and psychosocial risk significantly predicted psychiatric rehospitalization. Clinician beliefs did not moderate the relationship between empowering clinician behaviors and psychiatric rehospitalization. Additionally, nearly one-quarter of the children were rehospitalized within 90 days of discharge. Most of the children rehospitalized within the intervening period, were previously hospitalized, had 1 to 2 psychosocial risk factors, longer lengths of stay and were diagnosed with an internalizing disorder. The findings presented may be used to inform research, practice and policies aimed at improving mental health outcomes for children and adolescents with severe emotional and behavioral disorders

SOCIAL INTERACTIONS AND INSTRUCTIONAL PRACTICES AMONG ENGLISH AS FOREIGN LANGUAGE TEACHERS: LESSONS FROM TRENDS IN BENIN REPUBLIC

This study examines Social Interactions on Instructional Practices among EFL Teachers in some secondary schools in Benin Republic. The methodology guiding the research is induced by the study typology. It considers a sampled population of seventy- seven 77 respondents made up of male and female teachers of English. The data collection tools adopted to operationalize the research are questionnaire and interview guide. Data emanating from the questionnaire harvest are disaggregated along the frequency and percentage lines. As for the interview data they are analyzed against the backdrop of the research questions. The findings of the study reveal four interactions types among EFL teachers. Those are mainly collaboration, individualism, contrived collegiality and balkanization. The study also comes up with the view that EFL teachers’ instructional practices are significantly influenced by social interactions. Therefore, it is important that educational authorities promote social interactions among teachers in order to enhance effective teaching and learning of English language

Fast hashing to G2 on pairing friendly curves

When using pairing-friendly ordinary elliptic curves over prime fields to implement identity-based protocols, there is often a need to hash identities to points on one or both of the two elliptic curve groups of prime order $r$ involved in the pairing. Of these $G_1$ is a group of points on the base field E(\F_p) and $G_2$ is instantiated as a group of points with coordinates on some extension field, over a twisted curve E\u27(\F_{p^d}), where $d$ divides the embedding degree $k$. While hashing to $G_1$ is relatively easy, hashing to $G_2$ has been less considered, and is regarded as likely to be more expensive as it appears to require a multiplication by a large cofactor. In this paper we introduce a fast method for this cofactor multiplication on $G_2$ which exploits an efficiently computable homomorphism

On the final exponentiation for calculating pairings on ordinary elliptic curves

When using pairing-friendly ordinary elliptic curves to compute the Tate and related pairings, the computation consists of two main components, the Miller loop and the so-called final exponentiation. As a result of good progress being made to reduce the Miller loop component of the algorithm (particularly with the discovery of ``truncated loop\u27\u27 pairings like the R-ate pairing), the final exponentiation has become a more significant component of the overall calculation. Here we exploit the structure of pairing friendly elliptic curves to reduce the computation required for the final exponentiation to a minimum

Are shallow-water shrimps proxies for hydrothermal-vent shrimps to assess the impact of deep-sea mining?

Polymetallic seafloor massive sulphide deposits are potential targets for deep-sea mining, but high concentrations of metals (including copper - Cu) may be released during exploitation activities, potentially inducing harmful impact. To determine whether shallow-water shrimp are suitable ecotoxicological proxies for deep-sea hydrothermal vent shrimp the effects of waterborne Cu exposure (3 and 10 days at 0.4 and 4 μM concentrations) in Palaemon elegans, Palaemon serratus, and Palaemon varians were compared with Mirocaris fortunata. Accumulation of Cu and a set of biomarkers were analysed. Results show different responses among congeneric species indicating that it is not appropriate to use shallow-water shrimps as ecotoxicological proxies for deep-water shrimps. During the evolutionary history of these species they were likely subject to different chemical environments which may have induced different molecular/biochemical adaptations/tolerances. Results highlight the importance of analysing effects of deep-sea mining in situ and in local species to adequately assess ecotoxicological effects under natural environmental conditions.This work was developed under the MIDAS project (Managing im-pacts of deep-sea resource exploitation), funded by the EuropeanCommission, European Union, 7th Framework Programme under thetheme“Sustainable management of Europe's deep sea and sub-seafloorresources”(Grant Agreement 603418).

Measuring subjective well-being from a multidimensional and temporal perspective: Italian adaptation of the I COPPE scale

Background: The objective of this study is to present the psychometric and cultural adaptation of the I COPPE scale to the Italian context. The original 21-item I COPPE was developed by Isaac Prilleltensky and colleagues to integrate a multidimensional and temporal perspective into the quantitative assessment of people’s subjective well-being. The scale comprises seven domains (Overall, Interpersonal, Community, Occupation, Psychological, Physical, and Economic well-being), which tap into past, present, and future self-appraisals of well-being. Methods: The Italian adapted version of the I COPPE scale underwent translation and backtranslation procedure. After a pilot study was conducted on a local sample of 683 university students, a national sample of 2432 Italian citizens responded to the final translated version of the I COPPE scale, 772 of whom re-completed the same survey after a period of four months. Respondents from both waves of the national sample were recruited partly through on-line social networks (i.e. Facebook, Twitter, and SurveyMonkey) and partly by university students who had been trained in Computer-Assisted Survey Information Collection. Results: Data were first screened for non-valid cases and tested for multivariate normality and missing data. The correlation matrix revealed highly significant correlation values, ranging from medium to high for nearly all congeneric variables of the I COPPE scale. Results from a series of nested and non-nested model comparisons supported the 7-factor correlated-traits model originally hypothesised, with factor loadings and inter-item reliability ranging from medium to high. In addition, they revealed that the I COPPE scale has strong internal reliability, with composite reliability always higher than .7, satisfactory construct validity, with average variance extracted nearly always higher than .5, and and full strict invariance across time. Conclusions: The Italian adaptation of the I COPPE scale presents appropriate psychometric properties in terms of both validity and reliability, and therefore can be applied to the Italian context. Some limitation and recommendations for future studies are discussed

Mixed-forest species establishment in a monodominant forest in Central Africa: Implications for tropical forest invasibility

Background: Traits of non-dominant mixed-forest tree species and their synergies for successful co-occurrence in monodominant Gilbertiodendron dewevrei forest have not yet been investigated. Here we compared the tree species diversity of the monodominant forest with its adjacent mixed forest and then determined which fitness proxies and life history traits of the mixed-forest tree species were most associated with successful co-existence in the monodominant forest. Methodology/Principal Findings: We sampled all trees (diameter in breast height [dbh]≥10 cm) within 6x1 ha topographically homogenous areas of intact central African forest in SE Cameroon, three independent patches of G. dewevrei-dominated forest and three adjacent areas (450-800 m apart). Monodominant G. dewevrei forest had lower sample-controlled species richness, species density and population density than its adjacent mixed forest in terms of stems with dbh≥10 cm. Analysis of a suite of population-level characteristics, such as relative abundance and geographical distribution, and traits such as wood density, height, diameter at breast height, fruit/seed dispersal mechanism and light requirement-revealed after controlling for phylogeny, species that co-occur with G. dewevrei tend to have higher abundance in adjacent mixed forest, higher wood density and a lower light requirement. Conclusions/Significance: Our results suggest that certain traits (wood density and light requirement) and population-level characteristics (relative abundance) may increase the invasibility of a tree species into a tropical closed-canopy system. Such knowledge may assist in the pre-emptive identification of invasive tree species. © 2014 Peh et al
