Factor interaction influences on human performance in air traffic control: the need for a multifactorial model

In air traffic management (ATM) knowledge of the impact of human factors on performance is critical to address safety incidents. Previous research has largely focused on the effects of single factors on performance which has resulted in a comprehensive understanding of single factor effects. In current control environments however, the residual threats for incidents often result from the interaction of multiple human factors and the resulting cumulative impact on performance. This research uses a literature review, an analysis of over 400 European aviation incident reports and finally a survey of ATM professionals to assess the need for a multifactorial model of performance. Literature findings suggest that Human Factors approaches are fundamentally single-factor in nature, which is out of step with real ATM working contexts. An incident report analysis, supported by a survey of air traffic experts, suggests that multiple factor incident causation exists. This discrepancy suggests the need for a new approach to looking at how incidents occur, and their factors managed, on a day-to-day basis. The proposed solution is a multifactorial model of human performance.     

Hazard identification and pre-map with a simple specific tool: synthesis of application experience in handicrafts in various productive sectors

In August 2009, an international group was founded with the task of developing a "toolkit for MSD prevention" under the IEA and in collaboration with the World Health Organization.According to the ISO standard 11228 series and the new Draft ISO TR 12259 "Application document guides for the potential user", our group developed a preliminary "mapping" methodology of occupational hazards in the craft industry, supported by software (Excel?, free download on: www.epmresearch.org).The possible users of toolkits are: members of health and safety committees; health and safety representatives; line supervisors; foremen; workers; government representatives; health workers providing basic occupational health services; occupational health and safety specialists.The proposed methodology, using specific key enters and quick assessment criteria, allows a simple ergonomics hazards identification and risk estimation to be made. It is thus possible to decide for which occupational hazards a more exhaustive risk assessment will be necessary and which occupational consultant should be involved (occupational physician, safety engineer, industrial hygienist, etc.).The methodology has been applied in different situations of small and medium craftsmanship Italian enterprises: leather goods, food, technical dental work, production of artistic ceramics and stained glass, beekeeping activities. The results are synthetically reported and discussed in this paper.     

How to reduce workload--augmented reality to ease the work of air traffic controllers

In the future the air traffic will rise--the workload of the controllers will do the same. In the BMWi research project, one of the tasks is, how to ensure safe air traffic, and a reasonable workload for the air traffic controllers. In this project it was the goal to find ways how to reduce the workload (and stress) for the controllers to allow safe air traffic, esp. at huge hub-airports by implementing augmented reality visualization and interaction.     

Modeling activities in air traffic control systems: antecedents and consequences of a mid-air collision

In this article we present a model of some functions and activities of the Brazilian Air traffic Control System (ATS) in the period in which occurred a mid-air collision between flight GLO1907, a commercial aircraft Boeing 737-800, and flight N600XL, an executive jet EMBRAER E-145, to investigate key resilience characteristics of the ATM. Modeling in some detail activities during the collision and related them to overall behavior and antecedents that stress the organization uncover some drift into failure mechanisms that erode safety defenses provided by the Air Navigation Service Provider (ANSP), enabling a mid-air collision to be happen.     

Differential response in child protection: How much is too much?

Recurring maltreatment can have devastating, lifelong consequences for children who are victims of abuse and neglect. The primary mission of child protection services (CPS) agencies is to prevent the recurrence of child maltreatment by offering families services designed to prevent future maltreatment. In order for these services to be effective, however, families must actually engage in them. This study focuses on how differential response programs impact families' successful engagement in services as indicated by long-term child safety outcomes.Differential response refers to a dual track system that allows public CPS agencies to respond to accepted reports of child abuse or neglect with either a traditional investigative response (TR) or an alternative response (AR). The AR is designed to be a less authoritative and less adversarial approach to families presenting a low- to moderate-risk of maltreatment. The AR involves collaboration with the family in a comprehensive assessment of the family's needs, risks and strengths and a referral to services on a voluntary basis. States implementing DR systems statewide vary greatly in the percentage of accepted reports that are assigned to the AR track. The goal of this study is to determine what rate of AR utilization is most effective in reducing subsequent reports of abuse and neglect for cases assigned to the AR.This study compares child safety outcomes for children assigned to the AR and those assigned to the TR within each of the fourteen states which implemented DR statewide between 2000–2012. The analysis uses Cox proportional hazards regression. Data for this observational study are drawn from the 2000–2012 data in the National Child Abuse and Neglect Data System (NCANDS) child files. Child safety is measured by re-reporting of the child to CPS.The theoretical model underpinning the study is McCurdy and Daro's (2001) Integrated Theory of Participant Involvement (ITPI) which outlines a conceptual model of parental engagement in services. This study hypothesizes that AR utilization rates affect the risk level of cases assigned to the AR. The ITPI model offers a possible explanation as to why higher risk cases may not be as responsive to the AR approach which depends upon the family's voluntary participation in services.The key finding of this study is that, in states assigning > 33% of reports to the AR, children on the AR track are being re-reported at equal or higher rates than those on the TR track. Only in those states utilizing the AR track for < 33% of the cases are AR cases being consistently re-reported at lower rates than those on the TR track. This article explores ways to improve the accuracy of track assignment decisions to prevent the assignment of higher risk families to the alternative response.

How shall we design the future vehicle for Chinese market

Surface transportation system is developing very fast in China and the number of vehicles is increasing quickly as well. This development creates a lot of problems on traffic safety and the number of accident is also increasing. In this paper, we made deep analysis of different possible causes of safety problems through three aspects: the traffic environment and infrastructure, in-vehicle information system design and the characteristics of drivers. There are many factors in each aspects may contribute to the transportation safety problems. Problems with infrastructure design and traffic design contribute over 50% of the traffic accident. Another important factor is that people has very little traffic safety concept and very weak on understanding the important of right behavior on the road. This paper has pointed the urgent needs to study the human factors in road and transportation system and vehicle HMI design, as there are very few such studies available in literature based on Chinese situation. The paper also proposed the needs to develop proactive educational system that can promote driver's understanding of traffic safety and to take the right action during drive.     

Using human factors engineering to improve patient safety in the cardiovascular operating room

Despite significant medical advances, cardiac surgery remains a high risk procedure. Sub-optimal work system design characteristics can contribute to the risks associated with cardiac surgery. However, hazards due to work system characteristics have not been identified in the cardiovascular operating room (CVOR) in sufficient detail to guide improvement efforts. The purpose of this study was to identify and categorize hazards (anything that has the potential to cause a preventable adverse patient safety event) in the CVOR. An interdisciplinary research team used prospective hazard identification methods including direct observations, contextual inquiry, and photographing to collect data in 5 hospitals for a total 22 cardiac surgeries. We performed thematic analysis of the qualitative data guided by a work system model. 60 categories of hazards such as practice variations, high workload, non-compliance with evidence-based guidelines, not including clinicians' in medical device purchasing decisions were found. Results indicated that hazards are common in cardiac surgery and should be eliminated or mitigated to improve patient safety. To improve patient safety in the CVOR, efforts should focus on creating a culture of safety, increasing compliance with evidence based infection control practices, improving communication and teamwork, and designing better tools and technologies through partnership among all stakeholders.     

Gendered,Invisible Work in Non‐profit Social Service Organizations: Implications for Worker Health and Safety

Nonprofit organizations (NPOs) play an important role in the provision of health and social services. In Canada the nonprofit sector includes 7.5 million volunteers and employs over 1.6 million paid workers. The sector is overwhelmingly female‐dominated — women make up over 80 per cent of workers in these nonprofit services. Work performed by women has traditionally been undervalued and invisible. It has often been considered safe by researchers, employers, policymakers and sometimes even workers themselves. Although there is some indication that jobs in the restructuring social services sector can be characterized by constant demand, high stress and violence, research into the working conditions and health hazards of these types of jobs has not been a priority. Using data from a qualitative study examining work in NPOs, we trace the ways that work performed in these workplaces is both gendered and invisible. We identify three types of invisible labour. ‘Background work’ facilitates and supports more visible and recognized organizational activities. Certain organizational language obscures the full spectrum of work that takes place in the organizations and the risks it may involve. ‘Empathy work’ includes the relationship building, counselling and crisis intervention that comprise key components of social service delivery. ‘Emotional labour’ involves the management of client emotions and workers' own emotions in the process of working with clients and delivering care under conditions of scarcity and contraction. The invisibility of these activities means that much of the day‐to‐day work done in the organizations, while particularly important in the context of social service restructuring, is taken‐for‐granted and undervalued by organizational outsiders. As a result, many of the hazards present in the jobs are hidden from view and workers' health may be compromised. We argue that the invisibility and taken‐for‐grantedness of certain types of work in NPOs is reflected in, and constitutive of, particular exclusions and shortcomings of current occupational health and safety systems designed to protect the health of workers.     

Developing people in a network of relational practices: reflections on the role of social work education

The mission of social work education in Flanders is threefold: to deliver education, to conduct research and to provide services to society. In our opinion social work education has a critical and liberating function towards society and it must stimulate and develop a critical attitude amongst students. In this article we first focus on the educational dimension of social work education as we practise this in one institute. Next we describe how we realise our objectives as a social work education institute in relation to the professional field. The central concept of our vision is social work as a relational practice.

From probation to prevention: protecting college students and workers from animal hazards

OBJECTIVE: Our objective was to develop an organized system to assess individual and group exposure to animal hazards on a college campus. MAIN POINTS: The scope and complexity of college health services continue to expand as campuses confront unforeseen exposures and disease entities. Of great concern are students and faculty who are exposed to potentially life threatening and other serious conditions during their academic work. CONCLUSION: A college health service developed an effective animal-hazard surveillance questionnaire that could be scanned and analyzed for individual and group exposure to hazards and the presence or absence of protective measures. The college then provided appropriate preventive services.     

Private lives and public programs: an Australian longitudinal study of the elderly

Major late life events, reported in the Dubbo longitudinal study of older Australians, are used to examine the interaction of private lives with public programs. First, the data indicate strong supportive effects of publicly funded income, health, and aged care programs in reducing family burdens from major life changes. In particular, financial crises were rarely mentioned, directly or indirectly, as major threats. Next, the central role of informal social support in these events is demonstrated, first, as in previous studies, family support was responsive to risky events and to aging itself. Also, in new findings, one-third of surviving elderly respondents coped with the burdens of family crises as a substantial proportion of the "major" life changes that occurred over 13 years of the study. Within the security and support provided by the Australian welfare system, and with strong social networks, families with older persons in the Dubbo study manage multiple, major life changes. With rapid population aging, the development of more, and more easily accessible, services for a growing population of older people is a priority. The critical challenge will be to harmoniously grow public financing, private funding, and informal caregiving to deal with the growing burden arising from an aging society.     

Technology and School Social Work Services: Introducing Technology in an Alternative School

SUMMARY

The public school system, one of the largest human service institutions in our nation, is continuously engaged in a struggle to balance the needs of a growing and diverse population with continuing threats of budget cuts. Under these conditions, it becomes even more critical that school social workers understand and appreciate the role of technology in delivering and evaluating services. To assess the effectiveness of school social work services, evaluation will have to be planned for, and systems of data collection and processing will have to be conducted on an ongoing basis.

This paper outlines the process whereby school social workers in a local school district proceeded to introduce technology into their service delivery regimen. Secondly, the paper shows how such technology was, and may be, used to evaluate the services provided by school social workers in an alternative school.     

Perinatal AIDS:

Increasing attention must be given to the psychosocial needs of families with HIV-infected mothers, especially as it relates to permanency planning for children who survive their infected parent(s). Since these families are disproportionately African-American, developing culturally-appropriate services is paramount. Norwood (1988) projected between 52,272 and 72,000 uninfected children will be orphaned in New York City. In Michigan, to understand this problem better, a retrospective chart review utilizing Norwood's model was performed of the families of the 83 infants whose cord blood was positive for maternal HIV antibodies or who were congenitally infected with HIV.     

An evaluation study of a health education programme for rural women in Bangladesh

In the 1980s, 21 Health and Family Welfare Centres (HFWC) in Munchiganz district in Bangladesh extended health and family planning services and health education to satellite clinics in private homes. A family welfare visitor (FWV) would visit each clinic 2 times/week to conduct health education sessions and treat patients. HFWC also promoted 70 mothers' clubs to promote small family size. Some mothers' clubs even provide basic health services. In March 1985, HFWC designed a study to evaluate the effectiveness of its health education component. Interviews and observations constituted the methodologies used. Interviewers and staff who were to observe health education lessons attended an introductory workshop in which they designed questionnaires. Next participant conducted 1-2 interviews while doing their regular work to pilot test the questionnaires. They then went to another workshop where they received feedback and discussed problems before the main evaluation. The study coordinator made spot check observations while interviewers spoke with women after a session on safe childbirth or diarrhea. The coordinator also held weekly meetings with the interviewers to identify problems and maintain a common base. HFWC managers used the study results to design and implement a simple monitoring system, manageable by supervisors, and others in the same or in a similar position. A very important lesson learned was that any monitoring system should not disrupt the routine of regular supervisory work or the already tight working schedules. The system should be uncomplicated so supervisors can easily monitor the health education component. Finally monitoring standards need to be founded on a common understanding and feedback between planners and health educators.     

Private Lives and Public Programs

Abstract

Major late life events, reported in the Dubbo longitudinal study of older Australians, are used to examine the interaction of private lives with public programs. First, the data indicate strong supportive effects of publicly funded income, health, and aged care programs in reducing family burdens from major life changes. In particular, financial crises were rarely mentioned, directly or indirectly, as major threats. Next, the central role of informal social support in these events is demonstrated, first, as in previous studies, family support was responsive to risky events and to aging itself. Also, in new findings, one-third of surviving elderly respondents coped with the burdens of family crises as a substantial proportion of the “major” life changes that occurred over 13 years of the study. Within the security and support provided by the Australian welfare system, and with strong social networks, families with older persons in the Dubbo study manage multiple, major life changes. With rapid population aging, the development of more, and more easily accessible, services for a growing population of older people is a priority. The critical challenge will be to harmoniously grow public financing, private funding, and informal caregiving to deal with the growing burden arising from an aging society.     

The nexus between OSH and subcontracting

Subcontracting of specialized functions to external companies (e.g. cleaning or maintenance) is actually very common within several industries. These external companies' are called contractors and their contracting is often designated as outsourcing. Frequently contractors involve other companies (the sub-contractors) to assist them in fulfilling the contract, resulting in a complex chain of organizations focused on interchange of work - the contracting chain. Therefore in the same work site can coexist workers form the client-company and workers from the contractors and/or subcontractors. Since contractors perform their job in client's facilities, they can be exposed to hazards that are unknown to them. On other hand, workers of the client company can also be exposed to hazardous situations derived from the work performed by the contractors. The paper discusses how adequate occupational safety and health conditions can be assured when dealing with this kind of dynamic labor networks. Two case-studies and several examples coming from international literature will be presented.     

Ergonomic considerations in school environments - the need for widening the scope

Behaviour patterns specific to children pose them at greater risk of environmental hazards than adults. Ergonomics is the science of matching human interaction with the proximate environment. Conventionally ergonomic principles were applied on adult work places to ensure safety of the working environment. With emerging scientific evidence, school environments are being a focus to apply ergonomic principles. Children spend more time within schools during critical developmental stages of their life. Everybody feels that the schools are safe places, but they are not. A multitude of ergonomic hazards have been identified in school settings. Widespread mismatches between anthropometry and school furniture, heavy schoolbag carriage and unhealthy bag behaviour are significant. Negative effects range from general tiredness, musculoskeletal pains, spinal deviations, shoulder level shifts, injuries and psychological disturbances. There are fragmented efforts to widen ergonomic concepts to health care professionals and other stakeholders of child health. Addressing ergonomic issues will ensure that children, the future productive generation contributing to economic growth and development of a country, are provided with opportunities in a healthy environment. This paper emphasizes the need for a concerted effort on widening the scope of ergonomics to cater for the evolving demand.     

Child protection: a new approach in South Australia

This paper argues the case for an integrated approach to child protection services, embracing children's safety, risk and needs and incorporating formal assessment instruments. It then provides a brief overview of the new child protection system in South Australia. The steady rise in child abuse/neglect reports raises questions about how best to provide child protection services. Analysis of South Australian data suggests that much of the rise can be attributed to an increase in reports of neglect and emotional abuse and an increase in re‐notifications. This in turn raises questions about the traditional investigative approach. In 1995 Messages from Research advocated that agencies re‐focus on children's needs and concentrate less on investigations into safety and risk. The critical question is how to distinguish families requiring investigation from those needing support. The latest research suggests that such decision‐making in child protection is generally inconsistent and unreliable. This paper argues that statutory agencies should use formal assessment tools to determine the level and nature of their interventions. These arguments have been critical in the development of the new child protection model in SA, which relies on a centralized intake, differential response to reports and the structured decision‐making system. Initial evaluation of the new model indicates improvements in consistency of initial screening and responses to children in danger. Copyright © 1999 John Wiley & Sons, Ltd.
