The finite element analysis capabilities of DART and the design routines for the computerized design in accordance with CP 110 and BS 5337 are briefly described. The DART program is used to compare some reservoir roof systems including a novel floated dome. Temperature effects on reservoirs can appear to yield severe stresses, but do they? The DART program is used for the design of non‐axisymmetric loaded structures and examples are given of wind loads on water towers and chimneys. A simple procedure has been incorporated into DART to allow for soil—structure interaction. The DART program can print out reinforcing or prestressing requirements. An elementary cost study has been made on reservoir walls to compare the relevant merits of the two methods of design. A facility has been incorporated into the DART program to find the optimum shape of reservoirs and water towers for a given set of construction costs. The Dynamic Programming method has been used for this purpose. Natural frequencies and mode shapes can be determined by the DART program using the Sturm sequence property and inverse iteration respectively.

Today’s work environment requires a new type of leader development. It is no longer enough for leaders to be qualified and knowledgeable. Leaders must be focused, adaptable, and resilient in order to be effective amid the increasingly distracting and chaotic organizational world. We argue that current methods of leader development need to evolve to encompass leader well-being and focus on intrapersonal competencies in order to adequately prepare leaders for today’s stressful work world. We provide a holistic development framework for leaders which we believe is a better match for the intrapersonal capabilities required by leadership roles. Our approach is two-fold. First, we believe it is important to educate leaders on the potential interaction between the external sources of stress and leaders’ neurophysiological and subjective well-being. Second, we believe leaders need different development experiences, ones that can help renew psychological resources. We review four categories of holistic leadership practices – mindfulness, social connections, positive emotion inductions, and body-based practices – which can help to counter the effects of overload and exhaustion. We also discuss the future of holistic leader development and suggest directions for future research.

This paper aims to examine the formal and informal workplace learning of professional chefs. In particular, it considers chefs’ learning strategies and outcomes as well as the barriers to and facilitators of their workplace learning.

The methodology is based on in-depth, face-to-face, semi-structured interviews with 12 executive chefs from a variety of restaurant types. Chefs were asked questions that focused on how they learned, the learning outcomes that they experienced and factors that inhibited or facilitated their learning.

Findings suggest that the strategies, outcomes, barriers and facilitators experienced by professional chefs are similar in many respects to those of other occupational/professional groups. However, there were some important differences that highlight the context of chefs’ workplace learning.

The sample, which is relatively small and local, focuses on one city in Canada, and it is limited in its generalizability. Future research should include a national survey of professional chefs.

Using a qualitative approach, this in-depth study adds to the literature on workplace learning, strategies, outcomes, barriers, facilitators and context factors by addressing a relatively understudied profession.

In this chapter, I investigated how challenges (life events) are negotiated within families according to gender roles and their effect on marriage quality, life satisfaction, and psychological resilience in a nonclinical sample of heterosexual couples (N=159), age 23–78 (M=45.4, SD=11.2), with children (n=127) or childfree (n=32). Specifically, I accounted for the individual’s ability to share “hurt feelings” and foster intimacy within the couple, thus strengthening resilience and improving life satisfaction and hypothesized that the impact of negative life events on both relationship quality and life satisfaction could depend on the resilience levels of each partner and their ratio according to gender roles. Results confirmed the hypothesis and showed significant gender differences in the impact of negative life events on relationship quality, life satisfaction, ability to share hurt feelings, fear of intimacy, and resilience levels. Moreover, the ratio of the partner’s individual resilience affected the dependent variables differently by gender, its level interacted with the age of the couple’s first child (range: 2–54, mean: 21.4, SD: 10.4) and strongly depended on the occupation of the parents.

This study investigated disparities in dual diagnosis (comorbid substance use and depressive/anxiety disorders) among US adults by nativity and racial–ethnic origin and socioeconomic, cultural, and psychosocial factors that may account for the observed disparities.

The study drew on data from two waves of the National Epidemiological Survey on Alcohol and Related Conditions. Racial–ethnic categories included African, Asian/Pacific Islander, European, Mexican, Puerto Rican, and other Hispanic/Latino. Substance use and depressive/anxiety disorders were assessed per DSM-IV. A four-category measure of comorbidity was constructed: no substance use or psychiatric disorder; substance use disorder only; depressive/anxiety disorder only; and dual diagnosis. The data were analyzed using multinomial logistic regression.

The prevalence of dual diagnosis was low but varied by nativity, with the highest rates among Europeans and Puerto Ricans born in US states, and the lowest among Mexicans and Asians/Pacific Islanders. The nativity and racial–ethnic effects on likelihood of having dual diagnosis remained significant after all adjustments.

The limitations included measures of immigrant status, race–ethnicity, and stress and potential misdiagnosis of mental disorder among ethnic minorities.

This new knowledge will help to guide public health and health care interventions addressing immigrant mental and behavioral health gaps.

This study addressed the research gap in regard to the prevalence and correlates of dual diagnosis among immigrants and racial–ethnic minorities. The study used the most current and comprehensive data addressing psychiatric conditions among US adults and examined factors rarely captured in epidemiologic surveys (e.g., acculturation).

Presents a review on implementing finite element methods on supercomputers, workstations and PCs and gives main trends in hardware and software developments. An appendix included at the end of the paper presents a bibliography on the subjects retrospectively to 1985 and approximately 1,100 references are listed.

Biodiversity loss now ranks as one of the most significant global drivers of environmental change. In an increasingly urbanized world, there is enormous potential to address this problem through conservation, restoration, and creation of new urban ecosystems. This chapter explores how nature-based solutions (NBS) can contribute to addressing the urgent problem of biodiversity loss in a way that goes beyond just greening gray environments. It then explores the alignment (and misalignment) between the ways in which NBS is framed as a nature conservation tool globally and the ways in which biodiversity is considered in urban approaches to NBS. Finally, the chapter explores the ways in which NBS might become an essential part of the solution to biodiversity and ecosystem decline. It discusses how NBS can be effectively leveraged to address the biodiversity crisis in urban areas, through conservation, restoration, and efforts to create thriving places for both people and nature. Although the concept of NBS in urban areas is fairly divorced from its nature conservation origins, reconnecting with those ecological roots is important for creating biodiverse, resilient cities. In so doing, NBS could offer a unified concept for environmental management in urban areas that integrates the ecological benefits of nature conservation with an innovative focus on confronting major societal challenges. Though this is a demanding task, it could provide a fit-for-purpose approach for conserving biodiversity and supporting functional ecosystems in the Anthropocene.

Commissioned by the Ministry of Agriculture, Fisheries and Food, the Department of Health and carried out by Social and Community Planning Research and MRC Dunn Nutrition Unit, the dental hospitals of the Universities of Newcastle and Birmingham and the Department of Epidemiology of the University of London, this research forms part of the National Diet and Nutrition Survey. Set up in 1992 the surveys cover representative groups of the population and examine the diet of the over‐65s in terms of actual dietary intake, habits, energy and nutrient intakes, physical measurements. Regional and socio‐economic comparisons are made.

Management training and development is currently in vogue. There appears to be a growing belief in the benefits of investment in training and development. When a market is buoyant is the time to consider and anticipate the consequences of a future downturn in demand. Such a downturn in demand may demonstrate increasing pressure to “justify” investment in training and development. There is a long established academic body of knowledge on the subject of evaluating training and development. From research evidence and the authors′ experience, the sponsors and the providers of training and development pay scant attention to systematic evaluation of these activities and investments. It is the authors′ contention that when the market′s critical assessment of the value of training and development increases there will be an increasing interest in evaluation. An overview of the history of evaluation traditions is provided and the state of play is commented upon. It is noted that there is a shortfall between theory and practice. It is argued that evaluation is a worthwhile and important activity and ways through the evaluation literature maze and the underpinnings of the activity are demonstrated, especially to management. Similarly the literature on evaluation techniques is reviewed. Tables are provided which demonstrate areas of major activity and identify relatively uncharted waters. This monograph provides a resource whereby practitioners can choose techniques which are appropriate to the activity on which they are engaged. It highlights the process which should be undertaken to make that choice in order that needs of the major stakeholders in the exercise are fully met.
