Oil and gas exploration and production activities are carried out in hazardous environments in many parts of the world. Recent events in the Gulf of Mexico highlight those risks and underline the importance of considering human factors during facility design. Ergonomic factors such as machinery design, facility and accommodation layout and the organization of work activities have been systematically considered over the past twenty years on a limited number of offshore facility design projects to a) minimize the occupational risks to personnel, b) support operations and maintenance tasks and c) improve personnel wellbeing. During this period, several regulators and industry bodies such as the American Bureau of Shipping (ABS), the American Society of Testing and Materials (ASTM), the UK's Health and Safety Executive (HSE), Oil and Gas Producers (OGP), and Norway's Petroleum Safety Authority (PSA) have developed specific HFE design standards and guidance documents for the application of Human Factors Engineering (HFE) to the design and operation of Oil and Gas projects. However, despite the existence of these guidance and recommended design practise documents, and documented proof of their value in enhancing crew safety and efficiency, HFE is still not well understood across the industry and application across projects is inconsistent. This paper summarizes the key Oil and Gas industry bodies' HFE guidance documents, identifies recurring themes and current trends in the use of these standards, provides examples of where and how these HFE standards have been used on past major offshore facility design projects, and suggests criteria for selecting the appropriate HFE strategy and tasks for future major oil and gas projects. It also provides a short history of the application of HFE to the offshore industry, beginning with the use of ASTM F 1166 to a major operator's Deepwater Gulf of Mexico facility in 1990 and the application of HFE to diverse world regions. This latter point highlights the need to consider user populations when selecting HFE design criteria, an aspect strongly emphasized in current industry guidance.  相似文献

Using vignettes and online photos, this study explored the relationship between touch intimacy, biological sex, attachment, and the experience of jealous emotions in the context of seeing one’s partner touch a close, opposite-sex friend. Results indicated that hypothetical scenarios elicited significant emotional responses and increases in touch intimacy (as depicted in digital photos) heightened these responses. Males indicated more sexual arousal when seeing their partners interacting with a friend, while females indicated more sadness, fear, and envy. In terms of attachment, preoccupied individuals expressed the most anger and fear, dismissives and secures expressed the least envy and embarrassment, dismissives expressed the least fear, and fearfuls expressed the most sexual arousal. The two forms of touch (face touch and lower back touch) elicited stronger jealous emotions (anger, sadness, fear, and embarrassment) than no touch. Lastly, in regards to lower back touch, fearfully attached males responded with the most fear, females with the most anger, sadness, fear, and envy, and fearfully attached individuals the least amount of fear. This occurred despite the fact that face touch was characterized as more intimate than lower back touch; our results suggest that this form of touch may have been perceived as sexual. We relate our findings to the context of viewing digital photos on social networking websites.  相似文献

Increasingly, community coalitions are being developed to address a myriad of social challenges. However, documented research efforts related to planning processes associated with coalition formation are few. This case-study documents the use of concept mapping (CM) to d elineate a conceptual framework for developing a statewide kinship care coalition in one southeastern state. CM is a mixed-method research approach that analyzes qualitative data via nonmetric multidimensional scaling and hierarchical cluster analyses. After a review of relevant literature, this article discusses CM processes associated with this endeavor and examines implications for future use of CM for coalition formation and development.  相似文献

This research was designed to increase our understanding of how the motivational antecedents to childbearing and emotional responses to pregnancy affect the subsequent attachment bond of a toddler to his or her mother. Using a sample of 1,364 mothers and their newborns from the Study of Early Child Care, we tested a mother‐child influence framework hypothesized to mediate between the mother's preconception motivation and pregnancy wantedness and her child's security of attachment at 24 months. Almost all elements of the mediational sequence were confirmed in a structural equation model. We observed 2 unmediated pathways to attachment security, 1 from preconception motivation and 1 from parenting stress during infancy, and suggest interpretations of these unexpected pathways.  相似文献

This paper examines the critical interface between manufacturing, purchasing, and quality assurance by exploring the impact of two alternative structures of buyer and vendor communication on attempts to improve the quality of purchased items. Those two structures of communication are the parallel structure and the serial structure. The research analyzes and compares the advantages and disadvantages of these two specific communication structures; the results have implications for both researchers and managers. The analysis of data suggests that the parallel structure is associated with significantly higher levels of quality than the serial structure. From a managerial perspective, the results of the research suggest that manufacturers must consider the parallel communication structure as a viable alternative for improving the quality of purchased components. While this study has helped frame some key managerial issues, the need and opportunity for further research in related areas is delineated.  相似文献

Ivy Lee's 1905 “Declaration of Principles” has been called the “starting point of modern public relations,” but what did it mean in the context of his time? Analysis of press discussion finds that, while press agentry was connected to the circus and theater, “corporate publicity” was linked to Theodore Roosevelt's call for the release of financial information in the public interest. The paper confirms that scholars do not have a clear understanding of public relations history and identifies areas for further research.  相似文献

This article describes the Marriage and Family Therapy Practice Research Network (MFT‐PRN). The MFT‐PRN is designed to build a professional community based on practice‐informed research and research‐informed practice, increase the diversity of participants in MFT research, and unify researchers and clinicians. Clinics choose measures from a list that best represent their clinic needs. Clients' outcomes are assessed regularly, and therapists receive immediate graphical feedback on how clients are progressing or digressing. Data are pooled to create a large and diverse database, while improving client outcomes. We will discuss advantages of the MFT‐PRN for researchers, therapists, clients, and agencies, and provide one model that we hope will inform other collaborative clinical‐research models in the field of marriage and family therapy. Video Abstract is found in the online version of the article .  相似文献

ABSTRACT

This article provides a summary of salient trauma findings and conveys the dearth of research pertaining specifically to the trauma of elder abuse. This material, in conjunction with information contained in other articles composing this special issue, lays the foundation for advancing a trauma-informed approach to assisting older adults who have experienced polyvictimization. Informed by the findings presented and their extensive clinical experience with victims of violence, the authors suggest steps for providing a trauma-informed and victim-centered response to older adults who have suffered polyvictimization. These steps are then illustrated with an in-depth late-life polyvictimization case analysis.  相似文献

ABSTRACT

Research on Americans’ retirement readiness indicates a wide range of preparedness for the golden years. Called a “crisis” by researchers, retirement for some may include significant choices: continued employment or utilization of social welfare services. This article describes factors contributing to the retirement crisis and roles social workers can play in assisting older retirees. Disparity in household retirement savings exists by ethnicity. On the front lines serving aging individuals and their families, social work professionals are well situated to collaborate with individuals, and other providers, to address financial, social and emotional pillars necessary in facilitating a safe and secure retirement.  相似文献
