The purpose of this paper is to explore the role of fathers in the management of sleeping problems in children with autism and their perspectives of the impact of these difficulties on family life.

Semi-structured interviews with 25 UK-based fathers of children with autism were undertaken.

Two-thirds of fathers reported that their children experienced severe sleeping problems in the areas of bed-time resistance, sleep onset and night-time waking. Fathers were significantly involved in the management of these difficulties and reported a range of associated deleterious impacts on the family, including significant negative effects on paternal and maternal health, father’s employment, couple relationship and sibling experiences.

The interview sample cannot be said to be representative of all fathers of children with autism since the backgrounds of those taking part were relatively homogeneous in respect of ethnicity, marital status and level of education.

Improvements in effective, family-centred provision are urgently needed which employ a co-parenting, gender-differentiated methodology.

Given the severity and frequency of difficulties, sleeping problems in children with autism should be viewed as a significant public health concern.

This is one of the first studies, qualitative or quantitative, to explore the role and perspectives of fathers of children with autism in the important area of sleep management.

Sleep disorders are extremely common in children and young people, and even more so in those with developmental disabilities. This client subgroup may prove refractory to standard behavioural and other psychosocial interventions that usually help and it is frequent for clinicians to resort to medication approaches given the high levels of personal and family distress that result. There is a need not only for further well structured research in this field but also for efforts to tackle the frequent relative neglect by clinicians of more researched and considered approaches. This review examines these issues selectively, focusing on important clinical issues and predicaments, and attempts a start at an evidence‐based background for practical and rational prescribing in this area of common childhood psychopathology.

This investigation aims to reframe the sizeable literature on barriers and drivers for energy efficiency measures (EEMs) and the phenomenon of the energy efficiency gap. The authors identify a gap between academic methods and industrial needs, as well as a neglect of the cultural dimension, despite its considerable impact. On the basis of this insight, the purpose of this paper is to integrate all of the various influences on industrial energy behavior previously identified in the literature in a refined energy cultures framework.

This paper includes a systematic literature review of research in the field of energy management, energy efficiency and cultural aspects within barriers and drivers of energy behavior. The authors select and refine an existing energy cultures framework for the industrial context. To meet industrial needs, the authors applied an ontology mapping of its core elements onto an international standard common for industrial energy management practice.

First, the authors present a refined framework for industrial energy cultures incorporating past barriers and drivers as factors. The framework enables an evaluation of attitude and behavioral aspects, underlying technologies, organizational culture and actions related to energy as a system of interdependencies. Second, the factors are ranked on the basis of the number of appearances and empirical metadata. Economic aspects such as “purchase, installment and hidden costs”, “general investment and risk behavior” and “regulatory conditions” are the highest ranked factors, but “existing knowledge about EEM”, “hierarchy approach: top down” and “environmental concerns” follow closely and represent cultural aspects, which are still underrated. Third, while illustrating a successful mapping onto a standardized process of continuous improvement, the authors also argue for heightened academia–practice efforts.

Reframing the energy efficiency gap as a problem of what aspirations play a role, what technology is chosen and how technologies are used should increase the level of implementation of EEMs in the real business world. Introducing the refined energy cultures framework serves as a starting point for future transdisciplinary collaboration between academia and practice.

Targeting the energy efficiency gap is an essential part of the sustainable development goals. The refined energy cultures framework allows for a better understanding of the industrial energy behaviors that are responsible for a significant share of a company’s success. The introduction of energy cultures serves as a starting point for future scholarly research within sustainability management accounting.

The investigation combines existing research streams, their concepts and their results about cultural aspects related to energy efficiency for both academics and practitioners. This review is the first to capture all of the various factors analyzed in academic literature using the energy cultures framework as a basis. The authors add to the theoretical development of that framework with its application to the industrial context. This is identified as a gap. Its refinement helps to holistically understand barriers and drivers of industrial EEMs to support its practical implementation.

The political campaigns of Una Clarke and Major Owens show an interesting display of ethnic politics. In this paper, I argue that the presence of a Caribbean population in Brooklyn New York presents itself as a challenge to the already present African-American structure. The Caribbean politicians do not subscribe nor fully ally with the African-American politicians, and instead, seek to carve out a niche for themselves and utilize their ties to home in an effort to cajole the Caribbean populace for support. Through the purview of a political campaign in Brooklyn between an African-American incumbent and a Caribbean insurgent, I attempt to contribute to the transnationalist literature through illustrating the concept of the nation−state, which can be explained as an immigrant’s continual bond to their home country while living abroad.

The purpose of this chapter is to review the historical development of identity theory from 1988 to the present, and then outline some thoughts about future directions for the theory.

The chapter discusses major advances in identity theory over the past 25 years such as the incorporation of the perceptual control system into the theory, the introduction of “resources” in which symbolic and sign meanings are important, new views of the social structure, the relevance of the situation in influencing the identity process, the idea of different bases of identities, broadening our understanding of multiple identities, studying identity change, and bringing in emotions into the theory.

Throughout the review, empirical work is identified and briefly discussed that supports the major advances of the theory.

The chapter suggests a number of ways that identity theory may be developed in the future such as examining negative or stigmatized identities. Additionally, there is a discussion as to ways in which the theory may be tied to other theoretical traditions such as affect control theory, exchange theory, and social identity theory.

Identity theory has had a number of applications to various areas in society, including understanding crime, education, race/ethnicity, gender, the family, and the environment.

This is the most recent overview of identity theory over the past 25 years. It becomes clear to the reader that the theory offers a way of understanding the person as a cognitive, emotional, and behavioral agent who influences the structure of society but who is also influenced by the social structure.

This paper examines the Random Walk Hypothesis (RWH) for aggregate New Zealand share market returns, as well as the CRSP NYSE‐AMEX (USA) index during the 1980‐2001 period. Using several indices, we rely on the variance‐ratio test and find evidence to support the rejection of the RWH with some evidence of a momentum effect. However, we find evidence to suggest the behaviour of share prices to be time‐dependent in New Zealand. For example, we find the indices tested were closer to random after the 1987 share market crash. Further analysis showed even stronger results for periods subsequent to the passage of the Companies Act 1993 and the Financial Reporting Act 1993. We also find evidence that indices based on large capitalisation stocks are more likely to follow a random walk compared to those based on smaller stocks. For the USA index, we find stronger evidence of random behaviour in our sample period compared to the earlier period examined by Lo and Mackinlay (1988)

Summary Stress measurements using the blind hole drilling technique with electrical resistance strain gauges have been made on surfaces of an aluminium alloy which have been subjected to a variety of grit blasting treatments. Relationships between the induced stress and depth were determined for each treatment. It is shown that the magnitude and the depth of the induced compressive stress are particularly sensitive to variations in grit size and, to a much lesser extent, to changes in the nozzle air pressure, the angle of impact and the duration of the treatment. Discussion of the results is centred on the need for control of the operating variables in particular applications. (c) Copyright H.M.S.O. London 1979

IN A TECHNICAL PAPER at the 1966 Conference of the American Society of Tool and Manufacturing Engineers, L. D. Wells considers practical ways of evaluating cutting fluids. Some general agreement exists that the most satisfactory method is that of tool life study based on either complete failure or some agreed amount of wear. This is, however, relatively costly in terms of both time and material and hence many workers have developed accelerated bench tests using, for example radioactive tracers for wear determination or alternatively measuring a single property such as cooling power of a fluid. The author argues that as machining is a complicated process which involves plastic deformation, friction, wear and heat transfer it is unlikely that an accelerated test can yield valid results.
