Feeling of difficulty: An aspect of monitoring that influences control

This study aimed at delimiting possible relations of feeling of difficulty (FOD) with control ideas pertaining to a particular task. Participants were 274 students of 7th, 8th, and 9th grade. They were tested with two mathematical tasks; they were also asked to give ratings of the feeling of difficulty at 4 phases: In advance of problem solving, during planning of the solution, after solution production, and an overall estimation. Participants also gave ratings for control ideas such as need to know the rule, to do the computations right, to have practice, to use one’s thinking and to have help from others. Path analysis and ANOVAs were used for the identification of the relations and differentiations of ratings in the four phases of problem solving. Results indicated that FOD varied from phase to phase and influenced ideas related to control. Feeling of difficulty in the main was only indirectly related to performance via control ideas.     

Movement behaviors and their association with depressive symptoms in Brazilian adolescents: A cross-sectional study

Background:Physical activity,sleep,and sedentary behaviors compose 24-h movement behaviors and have been independently associated with depressive symptoms.However,it is not clear whether it is the movement behavior itself or other contextual factors that are related to depressive symptoms.The objective of the present study was to examine the associations between self-reported and accelerometer-measured movement behaviors and depressive symptoms in adolescents.Methods:Cross-sectional data from 610 adolescents(14-18 years old)were used.Adolescents answered questions from the Center for Epidemiological Studies Depression scale and reported time spent watching videos,playing videogames,using social media,time spent in various physical activities,and daytime sleepiness.Wrist-worn accelerometers were used to measure sleep duration,sleep efficiency,sedentary time,and physical activity.Mixed-effects logistic regressions were used.Results:Almost half of the adolescents(48%)were classified as being at high risk for depression(score≥20).No significant associations were found between depressive symptoms and accelerometer-measured movement behaviors,self-reported non-sport physical activity,watching videos,and playing videogames.However,higher levels of self-reported total physical activity(odd ratio(OR)=0.92,95%confidence interval(95%CI):0.86-0.98)and volume of sports(OR=0.88,95%CI:0.79-0.97),in minutes,were associated with a lower risk of depression,while using social media for either 2.0-3.9 h/day(OR=1.77,95%CI:1.58-2.70)or>3.9 h/day(OR=1.67,95%CI:1.10-2.54),as well as higher levels of daytime sleepiness(OR=1.17,95%CI:1.12-1.22),were associated with a higher risk of depression.Conclusion:What adolescents do when they are active or sedentary may be more important than the time spent in the movement behaviors because it relates to depressive symptoms.Targeting daytime sleepiness,promoting sports,and limiting social media use may benefit adolescents.     

Utility of icteric index in clinical laboratories: more than a preanalytical indicator

IntroductionTotal bilirubin tests are highly demanded in clinical laboratories. Since icteric index (I-index) has zero cost, we aimed to evaluate its clinical utility and cost-effectiveness to determine if total bilirubin is necessary to be tested. We took into account if haemolysis could interfere to icteric index determination.Material and methodsRetrospectively we reviewed I-index results in two cohorts (43,372 and 8507 non-haemolysed and haemolysed samples, respectively). All determinations were done using Alinity c chemistry analysers (Abbott Diagnostics). Receiver operating characteristic (ROC) curve was used to determine the optimal index cut-off to discriminate between normal and abnormal bilirubin concentration (20.5 µmol/L).ResultsThe ROC curve analysis suggested 21.4 µmol/L as the optimal I-index cut-off but differences in sensitivity and specificity were detected between patient derivation. For rejecting purpose, 15.4 µmol/L and 17.1 µmol/L I-index thresholds were selected based on patient derivation (inpatients and emergency room; and primary care and outpatients, respectively) with 97% sensitivity and 0.25% false negative results. Sensitivity was much lower in haemolysed samples. We selected 34.2 µmol/L I-index as threshold to detect hyperbilirubinemia with 99.7% specificity and 0.26% false positive results, independent of haemolysis. With the icteric index cut-offs proposed, we would save 66% of total bilirubin requested and analyse total bilirubin in around 2% of samples without total bilirubin requested.ConclusionsThis study supports the use of I-index to avoid bilirubin determination and to identify patients with hyperbilirubinemia. This work considers that the economic and test savings could help to increase the efficiency in clinical laboratories.     

School Choice and Social Injustice: A Response to Harry Brighouse

In his book, School Choice and Social Justice, Harry Brighouse attempts to show how a properly designed school–choice plan, guided by his liberal theory of social justice, can enhance equal educational opportunity and provide every child with an education for autonomy. In this paper, I argue that Brighouse is overly confident about the egalitarian potential of school choice. He seems to be defending a policy for what it could be, rather than looking at school choice for what it is: a flawed educational reform that makes things worse in terms of social justice. I question Brighouse's notion that the kind of school choice he advocates, one that promotes equal educational opportunity and education for autonomy, is politically feasible.     

A content analysis of school anti-bullying policies: a follow-up after six years

An analysis was undertaken of 217 English school anti-bullying policies, from 169 primary schools and 48 secondary schools, using a 34-item scoring scheme. Findings were compared with an analysis of 142 schools six years earlier. Overall schools in the current analysis had about 49% of the items in their policies, a modest increase over the previous study. Most included a definition of bullying and statements about improving school climate but many schools did not mention other important aspects, and there was low coverage of cyberbullying, homophobic bullying, bullying based on disabilities, or faith; teacher–pupil bullying; responsibilities beyond those of teaching staff; following up of incidents; and specific preventative measures such as playground work, peer support, inclusiveness issues, and bullying to and from school. Several improvements in policies, significant for 20 out of 34 criteria were noted. Findings are discussed in terms of national policy, and ways to support schools in maximising the potential of their policies for reducing bullying.     

SCHOOL PSYCHOLOGISTS AS MENTAL HEALTH PROVIDERS: THE IMPACT OF STAFFING RATIOS AND MEDICAID ON SERVICE PROVISIONS

As one out of five children in the United States demonstrate some type of mental or behavioral health concern warranting additional intervention, federal policies have emphasized the need for school‐based mental health (SBMH) services and an expansion of Medicaid reimbursement for eligible children and families. Most youth access mental health services at school; therefore, it is important to evaluate how staffing ratios, credentialing, and state Medicaid policies may influence school psychologists’ involvement in the delivery of SBMH services. A survey of 192 school psychologists found that as practitioner to student ratios increased, the availability and provision of SBMH services decreased. As state Medicaid policies have been found to influence the provision of mental health services at school, current study results demonstrate an association between state level Medicaid policies and the number of school psychologists qualified to bill for Medicaid‐reimbursable services. Implications for service delivery and policy development are discussed.     

Parenting behavior and the risk of becoming a victim and a bully/victim: A meta-analysis study

Objective

Being bullied has adverse effects on children's health. Children's family experiences and parenting behavior before entering school help shape their capacity to adapt and cope at school and have an impact on children's peer relationship, hence it is important to identify how parenting styles and parent–child relationship are related to victimization in order to develop intervention programs to prevent or mitigate victimization in childhood and adolescence.

Methods

We conducted a systematic review of the published literature on parenting behavior and peer victimization using MEDLINE, PsychINFO, Eric and EMBASE from 1970 through the end of December 2012. We included prospective cohort studies and cross-sectional studies that investigated the association between parenting behavior and peer victimization.

Results

Both victims and those who both bully and are victims (bully/victims) were more likely to be exposed to negative parenting behavior including abuse and neglect and maladaptive parenting. The effects were generally small to moderate for victims (Hedge's g range: 0.10–0.31) but moderate for bully/victims (0.13–0.68). Positive parenting behavior including good communication of parents with the child, warm and affectionate relationship, parental involvement and support, and parental supervision were protective against peer victimization. The protective effects were generally small to moderate for both victims (Hedge's g: range: −0.12 to −0.22) and bully/victims (−0.17 to −0.42).

Conclusions

Negative parenting behavior is related to a moderate increase of risk for becoming a bully/victim and small to moderate effects on victim status at school. Intervention programs against bullying should extend their focus beyond schools to include families and start before children enter school.     

Misconceptions on geometric optics and their association with relevant educational variables

The topic of geometrical optics was chosen to diagnose the preconceptions of 44 trainee teachers in this subject area. The scores obtained from a pretest were examined with respect to several variables describing cognitive, academic and social factors. The results suggest that both students’ level of cognitive development and their pre‐knowledge should be taken into account in developing an integrating paradigm for science teaching. Cognitive style appears as a further variable to be considered in this.
