Using a national data set from the Early Childhood Longitudinal Study – Birth Cohort, we examined factors associated with approximately 700 young African American boys’ pre-academic skills. The factors examined included (a) family characteristics, behaviors, and beliefs; (b) nonparental care literacy activities; and (c) child health, aggression, and approaches to learning (e.g., curiosity, independence, and persistence). High achieving boys are contrasted with other boys, along the following dimensions: familial, early childhood program, child characteristics and practices and their pre-academic skills, and whether the association was moderated by achievement status. Regression analyses indicated that some aspects of family, preschool, and child characteristics were associated with African American boys’ early outcomes, especially parental caretaking (e.g., bathing and brushing teeth) and approaches to learning (e.g., persistence and attention). Recommendations for educational practices and policies were offered.

In the field of behavioral disabilities, systematic direct observation (SDO) has been an integral tool for describing and explaining relationships between student and teacher behavior in authentic classroom settings. However, this method of measurement can be resource-intensive and presents a series of complex decisions for investigators. The purpose of this chapter is to review a series of critical decisions investigators must make when developing SDO protocols to address their research questions. After describing each decision point and its relevance to the measurement system, we identify trends and special considerations in the field of behavioral disabilities with respect to each decision. We organize content according to deciding what to measure, deciding how to measure it, and critical steps to prevent system breakdowns. Finally, we identify avenues for research to further the impact of SDO in the field of behavioral disabilities.

Recognizing the effects of dropping out of high school on society, several questions still remain: (a) Why do urban, African American male students drop out of high school? and (b) What makes these students more prone to dropping out than their counterparts who remain in school? In an attempt to better understand the lives and circumstances of African American males, this study uses a comparative case method to examine similarities and differences in the life histories of a matched sample of African American male high school graduates and dropouts. This study, specifically, focuses on how the interrelated factors of family, neighborhood, peers, and education may shape these youths’ perspective on school. Findings reveal that, while both groups experience high levels of risk factors, high school dropouts had significantly more risk experiences in the family, community, and criminal justice domains. The dropouts also had fewer protective factors in these domain areas. Based on the findings, recommendations are offered.

The purpose of this study was to test a new approach to deviancy training, that is, the shaping and reinforcing of disruptive behaviors in social interaction, which considers not only reinforcement, but also the modeling processes involved, as well as children's roles as either providers or receivers of the training.

Using teacher reports and observations from a semi-naturalistic experimental setting with young children, the authors examined the prevalence of provided and received modeling and positive reinforcement, as well as the concurrent contribution of behavior problems on these processes in friendship dyads using a convenience sample of six-year-old twins (N=783; 386 boys). Frequency analyses and linear and logistic regressions were conducted.

Results indicated that modeling and positive reinforcement – provided and received – were prevalent in this low-risk sample, that behavior problems were associated mainly with provided dimensions, and that deviancy training processes were also displayed between disruptive and non-disruptive children.

Findings are relevant to peer-oriented programs designed to prevent antisocial behaviors. Prevention should target these mixed friendships where deviant behavior likely begins.

This study provides preliminary support for a new measure of deviancy training, underscores the importance of the roles taken by children, and shows that deviancy training takes place between disruptive and non-disruptive young children.

Students’ antisocial behavior can often lead to violence in school. Longitudinal studies pertaining to antisocial behavior have contributed considerably to the development of knowledge in this field of research. This knowledge now enables us to identify the different developmental stages of aggressive and antisocial behavior during childhood and adolescence. Consequently, we are better able to identify antisocial behavior in the classroom, to describe the developmental pathways leading to antisocial behavior, to identify the risk factors relating to this issue and finally, to predict who might be at‐risk of developing antisocial behavior. In the past, antisocial behavior was conceived as following a single developmental pathway encompassing several categories of behavioral problems. Now, on the other hand, many studies demonstrate how the development of these behaviors can be explained through different pathways.

The purpose of this paper is to investigate the prevalence of aggressive behaviour among children and adolescents with intellectual disability (ID) and to demonstrate a possible link with moral judgement.

This study was carried out using two scales on a sample of 60 young people with ID in specialized schools. The first scale was “Behavior Problems Inventory-Short Form” (Rojahn et al., 2012) used to assess the frequency of aggressive behaviour and the second involved several scenarios about social situations of aggressiveness to assess moral judgement.

The main findings indicate that children and adolescents with ID gave more importance to the factor “consequences” than to that of “intent”. Moreover, there was a link between moral judgement and aggressive behaviour. Indeed, aggressive people found it harder to take into account the other’s point of view. Regarding moral judgement, they gave greater importance to the “consequences” factor than non-aggressive people.

The study aimed to establish, for the first time, a link between aggressiveness and moral judgement (blame) in ID (Anderson, 1996). This study clearly provides useful information regarding public health for patients, professionals and families. The authors were able to measure a similar frequency of aggressive behaviour in both children and adolescents with ID. The authors also highlighted a link between these aggressive behaviours and moral judgement. This knowledge should enhance understanding of manifestations of aggressiveness in this population, and improve diagnostic assessment. It should also help define appropriate directions for educational interventions to prevent the onset of aggressive behaviour or delinquency.

As a healthcare professional caring for people who lack capacity, the author has noted a wide variation in knowledge and awareness by staff of the Deprivation of Liberty Safeguards (DoLS). The purpose of this paper is to examine the DoLS and the background to their coming into being, describes their operation and qualifying requirements, and the continuing problems with their application nationwide.

Utilising a literature search of government papers, official reports of statutory bodies, and critical studies, it examines the central criticisms of DoLS, particularly the lack of a clear statutory definition of deprivation of liberty, and reports on the wide variation in knowledge of the legislation by staff in health and social care, and uneven application of the safeguards nationwide.

It cites evidence from studies showing that even professionals with high levels of expertise in the field find the legislation confusing, and presents testimony from legal experts that case law has failed to clarify the issues for professionals.

Finally, it argues that the legislation is now too complex to successfully amend, and tentatively suggests that, pending a government review to make the process more understandable, health care professionals make ‘precautionary’ applications for DoLS. The author argues that, notwithstanding its faults, the process is a worthwhile exercise in care planning and ensuring that people's care is in their best interests and the least restrictive available.

In this paper, we discuss methods to integrate ecological resources, ecosystem services, risk, and the transition to long-term stewardship on Department of Energy lands. Three types of information are required about ecological resources before decisions can be made about remediation, site transitions, and long-term stewardship: (1) the ecological resources and ecosystem functions (such as productivity) present on site and their spatial pattern, (2) the ecosystem services these resources provide to people, and (3) the risks from the interactions between people and these ecosystems. Once the ecological resources and ecosystem services are evaluated, then decisions about future land use, preservation, conservation, or protection of ecological resources within a designated land use can be implemented. Long-term stewardship requires both ecosystem protection in terms of biological resources and ecosystem function as well as biomonitoring to ensure minimal radiological or chemical risk and to inform future management. In some cases, protection of ecological resources may be preferable to cleanup that is physically disruptive, provided land use designation is consistent with ecological protection. In such instances, less site cleanup can prove preferable to more.

The high prevalence of bullying in South African schools in recent times is a cause for serious concern. Bullying is traumatic and has a painful, corrosive and damaging impact on children, families and society. Hence, curbing the problem before it spirals out of control in secondary schools requires immediate urgent attention from all stakeholders of the school. The purpose of this paper is to report on part of the investigation done for a doctoral thesis (Singh, 2016), which looked at the factors contributing to bullying perpetration in secondary schools and on the basis of the findings, recommend a model that may be used to curb bullying in secondary schools. A qualitative research design was used to investigate the problem through an interview process with participants from secondary schools, as well as a circuit manager from the Uthungulu district of KwaZulu-Natal. The findings confirmed that the problem of bullying emanated at the level of the family, the school and the community. The paper concludes with the provision of a model to manage and curb bullying in these secondary schools.

A qualitative research approach, in particular a case study design, was selected to give a clear understanding of participants’ views and experiences (Johnson and Christensen, 2011; Mason, 2013). The design involved a social constructivist paradigm, which was primarily concerned with meaning and understanding people’s “lived experiences” and “inner-worlds” in the context of the conditions and circumstances of their lives, which in this particular instance was bullying in secondary schools, occurring within a social context, which was the school (Johnson and Christensen, 2011). Purposeful sampling was used to identify five secondary schools in the Uthungulu district of KwaZulu-Natal where the problem of bullying was most prevalent principals at circuit and district-level meetings complained about the high incidence of bullying perpetration in their schools.

This paper highlights the findings in respect of the factors contributing to bullying perpetration in schools and presents a management model to curb bullying in secondary schools in KwaZulu-Natal. Factors contributing to bullying: the findings from the empirical investigation avowed that the three key factors contributing significantly to bullying behaviour are located at the level of the family, the school and the community. First, influence at family level: “60–70 per cent of our learners come from broken homes”. An overwhelming majority of participants in all five secondary schools attributed the escalation of bullying in schools directly to the influence at the family level. Broken homes, poor upbringing, the absence of positive role models and the influence of media violence on learners have had a negative impact on the culture of discipline, teaching and learning in the classroom and the general ethos of schools. Second, influence at school level: “the foremost problem here is peer pressure”. An overwhelming number of participants identified several factors at the school level that contributed to bullying in secondary schools. Learner 3 (School A) highlighted the problem of peer pressure and the need to belong to a group as a critical factor in advancing bullying in schools. Third, influence at community level: “they come from that violent environment”. Participants explained that the absence of after-school programmes and a lack of facilities, particularly in rural communities, misdirected youngsters into engaging in other destructive vices such as forming gangs and indulging in drugs and alcohol, to keep themselves occupied.

Various studies have been conducted in South Africa to understand the phenomenon of bullying and violence in South African schools. While the current body of research highlights the problem of bullying in schools and provides some guidelines on what measures may be adopted to address the problem, the suggested methods are not effective enough, resulting in the problem continuing unabated. This study therefore suggests a model to manage and curb bullying in secondary schools in South Africa.

Computer simulations were done extensively in order to study non‐linear dynamics of laser‐plasma interaction in InSb semiconductor. We constructed the modified Duffing kind of non‐linear semiconductor plasma oscillator equation. Collision frequency is found to be dominant parameter to influence the bifurcation, chaos, hysteresis and bistable effects of plasma wave. Small windows of higher period cascade above the critical value of laser parameter (α₁α₂) in the chaos region are observed. Laser‐plasma exhibits too much chaotic regime at lower value of laser driving frequency (δ). Hysteresis and bistable regions of plasma wave are presented and the conditions for their occurence are identified. The unstable regions completely merge at higher value of effective collision frequency (γ).
