One limitation of research that assesses the effectiveness of physical activity interventions for people with dementia is that most do not describe the intervention in sufficient detail to ascertain a theoretical basis or mechanism of action that determines the effective components. This paper aims to identify studies which evaluate the mechanisms of action of physical activity interventions for people with dementia, to further inform effective intervention development.

Papers were screened for evidence of evaluation of specific forms of physical activity, using pre-defined inclusion criteria. Analysis was conducted to ascertain if mechanisms of action were corroborated by data within and between studies.

The authors identified 26 studies with a measured mechanism of action; these related to the effects of physical activity on either neurological structure or endocrinal markers, including hormones. Physical activity had potential to reduce hippocampal atrophy, increase neural recruitment, activate the noradrenergic system and improve anti-inflammatory responses. While individual studies were hampered by small sample sizes, the body of evidence indicated that physical activity may have potential to delay cognitive decline.

Mechanisms of action in relation to dementia and physical activity are likely to be multifaceted, and physical activity may be protective against progression in the early stages of cognitive decline. Physical activity may be of greatest benefit if incorporated into on-going lifestyle, rather than engaged in for short periods, and combined with social interaction.

This paper is unique in its focus on the mechanisms of action of physical activity interventions for people with dementia.

Childhood-onset schizophrenia (COS) refers to schizophrenia with onset of psychotic symptoms prior to a child's 13th birthday. Optimal treatment likely includes family-based services supplementing antipsychotic pharmacotherapy. However, family-based services can require adjustment based on parental psychopathology; there has been little literature exploring the frequency or type of psychopathology seen in parents of COS cases. This report includes the results of a structured psychiatric evaluation on 80 parents of a COS case with comparison to a sample of 304 parents. Having a child with psychosis and being of minority racial/ethnicity status increased risk for psychiatric illness. Psychotic disorders (15% vs. 5%), mood disorders (54% vs. 27%), anxiety disorders (30% vs. 18%), and substance use disorders (49% vs. 31%) were all increased in the parents with a psychotic child. Psychiatric illness is common in parents of a child with COS and will need to be considered as family-based services for COS are developed.

Children with Autism Spectrum Disorder (ASD) show reduced attention to social stimuli. The reasons for these impairments are still being debated by researchers. The aim of this study is to analyse if reduced attention towards social stimuli is determined by initial underlying difficulties in the control of visual attention. Among the variables that could produce these difficulties, the authors considered geometric complexity and typology of geometric figures.

To test this hypothesis, in this paper, an eye-tracker paradigm was used for assessing visual exploration and recognition memory towards geometric figures (curved vs rectilinear) with two levels of geometric complexity (low and high) in 17 children with ASD matched with 17 children with typical development (TD).

The results showed that the ASD group seemed indifferent to both the geometric complexity and the typology of figures (curved and rectilinear), whereas the TD group showed higher performances with highly complex and curved geometric figures than with low complex and rectilinear geometric figures.

Because of the chosen research approach, the research results may lack generalizability. Therefore, researchers are encouraged to test the proposed hypotheses further.

This paper includes implications upon the presence of an unspecified visual attention deficit that is present from the early stages of the processing of stimuli.

The understanding of this deficit from the early stages of the processing of stimuli can help educators to intervene at an early stage when disturbances in social relationships are starting.

This study contributes to understanding the presence of dysfunctional perceptual antecedents that could determine general difficulties in paying attention to social stimuli in ASD subjects.

Self-efficacy has often been found to play a significant role in healthy dietary behaviours. However, self-efficacy interventions most often consist of intensive interventions. The authors aim to provide more insight into the effect of brief self-efficacy interventions on healthy dietary behaviours.

In the present article, two randomized controlled trials are described. In study 1, a brief self-efficacy intervention with multiple self-efficacy techniques integrated on a flyer is tested, and in study 2, an online brief self-efficacy intervention with a single self-efficacy technique is tested.

The results show that a brief self-efficacy intervention can directly increase vegetable intake and indirectly improve compliance to a diet plan to eat healthier.

These findings suggest that self-efficacy interventions do not always have to be intensive to change dietary behaviours and that brief self-efficacy interventions can also lead to more healthy dietary behaviours.

The purpose of this paper is to examine the effect of the intensive lifestyle modification program on weight and metabolic syndrome risk reduction in rural obese women who have no underlying non-communicable diseases in Thailand.

A randomized controlled trial was conducted. In total, 60 healthy obese women aged 30-50 years were recruited and randomly assigned to either the intervention (n=30) or control (n=30) group after health screening. Tailored nutritional counseling, health education and exercise training were included in the lifestyle modification program. Behavioral modification techniques were also incorporated. The intervention was conducted weekly for the first eight weeks, then biweekly until week 16.

The student’s t-test was used to compare mean difference between groups. The total weight loss in the intervention group (n=29) was significantly higher, 7.6±2.9 kg, compared with the control group (n=30) who lost 0.7±1.4 kg (p<0.001). The intervention group lost weight 10.2 percent from baseline which was significantly higher than that in the control group (p<0.001). Systolic and diastolic blood pressures, fasting blood sugar, and waist circumference were significantly improved. Triglyceride levels slightly improved while high density lipoprotein cholesterol was slightly lowered. The intervention group showed a statistical reduction in abnormal components of metabolic syndrome compared with the control group, with the relative risk=0.24, 95% confidence interval=0.072-0.791, and p=0.018.

Compatibility of the program activities conducted by a health professional who had achieved healthy weight loss and accepted as a role model was a key to achieving effective weight loss and metabolic syndrome risk reduction in obese women in rural areas. The program should be integrated into the conventional practice of health care centers.

This article theoretically analyzes how response to intervention (RTI) can be used as a tool in lesson study (LS) to enhance student learning and how RTI can be made more user-friendly by teachers in LS. The focus is on how RTI can be adapted to teachers' daily work by including it in the LS model and how LS can benefit by introducing a scientific approach in analyzing student learning outcomes through RTI. The article also highlights how this approach can contribute to learning for children with special educational needs (SEN).

This theoretical paper describes and compares the characteristics of the LS model with the RTI framework. The comparison highlights the design of models related to teachers’ development and learning outcomes. The benefits and challenges with the models are described. A previous research study related to the models is also briefly reviewed.

There are benefits and challenges with both the RTI and LS models but parts of the models appear to complement one another to some extent. Teachers' professional development and a better control of learning outcomes could be gained by combining the models. This could also lead to educational improvement.

There has been almost no research about a combined LS and RTI model.

The purpose of this paper is to illustrate an interdisciplinary system of targeted student supports, drawing from social and emotional learning (SEL), culturally responsive practices (CRP) and positive behavioral interventions and supports (PBIS). While these approaches are not often synthesized in research literature, innovative educators are integrating multiple theories and practices to achieve better outcomes for students.

The paper uses a descriptive, participatory case study method, including quantitative and qualitative data from a three-year period. The author was a participant in the change process, as well as an observer documenting the outcomes. The case study takes place in a Spanish/English bilingual elementary school.

PBIS was a strong influence in the three-year systems change process, due in part to the availability of free, research-based tools. The educators adapted PBIS practices to incorporate SEL, and CRP approaches in several instances. Quantitative data show the increase in PBIS implementation fidelity and one student’s progress with a targeted intervention. Qualitative data illustrate the creative, interdisciplinary and contextualized adaptations made by the team.

Guidance is available for educators seeking to implement SEL, CRP and/or PBIS approaches in isolation. To a lesser extent, integrated models are emerging in the literature. There is a need for more descriptive, real-world case examples of how these approaches are implemented and adapted in practice. This study provides educators with one example that can offer examples and implications for practice.

This study aims to understand the extent to which a faculty development program that includes a week-long course design experience followed by sustained support changes new faculty's perceptions, beliefs and teaching practices. The authors employed the teacher professional knowledge and skill (TPK&S) framework and characteristics of effective educational development interventions to drive the program development, implementation and assessment.

This study utilized a mixed methods approach. Data sources include pre-/mid-/post-program responses to a validated survey, pre-/post-program course syllabi analyzed using a validated rubric and pre-/post-classroom observations collected using the Classroom Observation Protocol for Undergraduate STEM (COPUS) instrument.

Findings indicate transformative effects for participants' beliefs about their teaching and changes to their instructional practices. Significant and practical effects were observed across different portions of the program for increases in participants' self-efficacy, endorsement of a conceptual change approach toward teaching and perceptions of institutional support. Participants produced more learning-focused syllabi and many moved toward more student-centered instructional approaches in their teaching practices.

Due to the voluntary nature of the new faculty development program, this study may have been limited by participant self-selection bias and differential sample sizes for the study's individual measures. Future research should consider designs which maximize faculty participation in measurement across all data sources.

This study addresses shortcomings in prior studies which utilized limited data sources to measure intervention impact and answers the call for more rigorous research to obtain a more complete picture of instructional development in higher education.

The purpose of this paper is to review the evidence of alcohol use disorders within the different stages of the criminal justice system in the UK. Furthermore it reviewed the worldwide evidence of alcohol brief interventions in the various stages of the criminal justice system.

A rapid systematic review of publications was conducted from the year 2000 to 2014 regarding the prevalence of alcohol use disorders in the various stages of the criminal justice system. The second part of the work was a rapid review of effectiveness studies of interventions for alcohol brief interventions. Studies were included if they had a comparison group. Worldwide evidence was included that consisted of up to three hours of face-to-face brief intervention either in one session or numerous sessions.

This review found that 64-88 per cent of adults in the police custody setting; 95 per cent in the magistrate court setting; 53-69 per cent in the probation setting and 5,913-863 per cent in the prison system and 64 per cent of young people in the criminal justice system in the UK scored positive for an alcohol use disorder. There is very little evidence of effectiveness of brief interventions in the various stages of the criminal justice system mainly due to the lack of follow-up data.

Brief alcohol interventions have a large and robust evidence base for reducing alcohol use in risky drinkers, particularly in primary care settings. However, there is little evidence of effect upon drinking levels in criminal justice settings. Whilst the approach shows promise with some effects being shown on alcohol-related harm as well as with young people in the USA, more robust research is needed to ascertain effectiveness of alcohol brief interventions in this setting.

This paper provides evidence of alcohol use disorders in the different stages of the criminal justice system in the UK using a validated tool as well as reviewing the worldwide evidence for short ( < three hours) alcohol brief intervention in this setting.
