The FARSEEING real-world fall repository: a large-scale collaborative database to collect and share sensor signals from real-world falls

Background

Real-world fall events objectively measured by body-worn sensors can improve the understanding of fall events in older people. However, these events are rare and hence challenging to capture. Therefore, the FARSEEING (FAll Repository for the design of Smart and sElf-adaptive Environments prolonging Independent livinG) consortium and associated partners started to build up a meta-database of real-world falls.

Results

Between January 2012 and December 2015 more than 300 real-world fall events have been recorded. This is currently the largest collection of real-world fall data recorded with inertial sensors. A signal processing and fall verification procedure has been developed and applied to the data. Since the end of 2015, 208 verified real-world fall events are available for analyses. The fall events have been recorded within several studies, with different methods, and in different populations. All sensor signals include at least accelerometer measurements and 58 % additionally include gyroscope and magnetometer measurements. The collection of data is ongoing and open to further partners contributing with fall signals. The FARSEEING consortium also aims to share the collected real-world falls data with other researchers on request.

Conclusions

The FARSEEING meta-database will help to improve the understanding of falls and enable new approaches in fall risk assessment, fall prevention, and fall detection in both aging and disease.

     

Scenario Tree Modeling to Analyze the Probability of Classical Swine Fever Virus Introduction into Member States of the European Union

The introduction of classical swine fever virus (CSFV) into a country free of disease without vaccination may have huge consequences in terms of both disease spread and economic losses. More quantitative insight into the main factors determining the probability of CSFV introduction (PCSFV) is needed to optimally use resources for the prevention of CSFV introduction. For this purpose a spreadsheet model was constructed that calculates the annual PCSFV into member states of the European Union (EU). The scenario pathway approach was used as most probabilities in the model are very small. Probability distributions were used to take into account inherent variability of input parameters. The model contained pathways of CSFV introduction including the import of pigs and pork products, returning livestock trucks, and contacts with wild boar. All EU member states were included as possible sources of CSFV. Default results for the Netherlands showed a mean overall annual PCSFV of approximately 0.06, indicating that the Netherlands can expect CSFV introduction on average once every 18 years from the pathways and countries included in the model. Almost 65% of this probability could be attributed to the pathway of returning livestock trucks. The most likely sources of CSFV introduction were Germany, Belgium, and the United Kingdom. Although the calculated probabilities were rather low when compared with expert estimates and recent history, the most likely causes of CSFV introduction indicated by the model were considered to be realistic. It was therefore concluded that the model is a useful tool to structure and analyze information for decision making concerning the prevention of CSFV introduction.     

Living Close to a Person With Cancer: A Review of the International Literature and Implications for Social Work Practice

To help family caregivers (FCs), social workers need to understand the complexity of FC’s experiences and challenges. For this systematic review, several relevant, multidisciplinary electronic databases were searched. Of 1,643 titles identified, 108 articles met the inclusion criteria and are included in this review. Various experiences, symptoms, and burden related to caregiving responsibilities are described and discussed. The understanding evolving from this study about the FC’s own health risk, caregiver burden, and experiences over time can enhance a social worker’s awareness of an FC’s challenging situation and the potential impact this has on the FC’s ability to provide care to the patient.     

Exploring death anxiety among elderly people: a literature review and empirical investigation

Given the growing number of elderly persons in society and concerns about their health and well-being, the aim was to review the available literature on their death anxiety, and to explore features of this experience among a small sample of older men and women in care facilities. In both the review and empirical parts of this study, components and correlates of death anxiety were investigated. The review revealed limited research focus on death anxiety among the elderly, particularly among those in institutions, but suggested both components and correlates for inclusion in our empirical study. Results showed that, among our elderly participants in an assisted living facility (N = 49; age range: 60-96 years), there were higher levels of fear for others and of the dying process than for fear of the unknown. Notably, among the correlates identified, fear for significant others was associated with poor physical health; fear of the dying process was related to low self-esteem, little purpose in life, and poor mental well-being. Gender differences in death anxiety were found: women showed greater fear for the death of loved ones and for the consequences of their own death on these loved ones, than did men. These patterns are discussed in the light of concerns about the welfare of elderly persons; scientific implications are also considered.     

Introducing a novel approach to the cross-cultural measurement of stigma versus social integration using methods from the field of cognitive anthropology

This study combines current theories and methods from the field of disability studies and cognitive anthropology in the development of a cross culturally replicable and comparative model for evaluating stigma toward, versus social integration of, people with disabilities in society. Weaknesses in previous ways of measuring and comparing ‘social integration’ are addressed, as well as known challenges of measuring attitudes and stigma toward disability, especially in a cross-culturally applicable and comparative way. A new application to previously existing methods in the field of cognitive anthropology is introduced which addresses these challenges. A case study conducted in Poland is described which illustrates the proposed methods. In conclusion, a roadmap for future research is provided which briefly reiterates the steps needed to replicate the study in various cultural contexts. Understanding the ways in which people with disabilities are perceived to deviate from culturally shared norms in a society may pave the way for the development of more effective and culturally targeted social policies in an effort to promote the social integration of all members of society.     

Service tasks of board of directors: A literature review and research agenda in an era of new governance practices

In their seminal review article on board of directors, Johnson, Daily, and Ellstrand (1996) distinguished between the control, service, and resource dependence tasks of the board and called for a stronger focus on board service tasks. Following this call, service tasks of boards have been subject to increased scholarly attention, with new theoretical perspectives and methods introduced. This paper aims at presenting the current state of research on board service tasks, departing from, and building on, the contribution of Johnson and colleagues. In doing so, we employ an Input-Process-Output-Context framework and craft an agenda for how future research could accommodate new governance practices and progress the field. Our review is relevant and timely as studies on the subject are gaining traction both in corporate governance and general management journals. Furthermore, our review on board service tasks proposes new alternative approaches to studying corporate governance which are especially appropriate in times in which a rethink of corporate governance frameworks and concepts is urgently needed.     

Potentials,problems and possibilities for developing New Zealand’s built environment through high-value geospatial information

Gaining useful information about our built, social and natural environments is vital and possible. The value of data for cities is more informed, more effective management and development choices resulting in more benefits to a greater range of stakeholders. This article explores the state-of-play of data infrastructures in New Zealand to identify the challenges to gaining better value from geospatial information. Following engagement with built environment data custodians and information users, it analyses how digital information infrastructure can support the sharing and use of richer and more comprehensive information by weaving a supportive fabric across data. The analysis reveals that data infrastructures primarily need to facilitate agreement on data management, sharing and use; the sharing of costs and benefits across stakeholders; and emphasise place as a powerful driver to richer information. An overarching sociotechnical approach to digital information infrastructure weaves data platforms, policy and technology together.     

Sensitivity Analysis to Evaluate the Impact of Uncertain Factors in a Scenario Tree Model for Classical Swine Fever Introduction

Introduction of classical swine fever virus (CSFV) is a continuing threat to the pig production sector in the European Union. A scenario tree model was developed to obtain more insight into the main risk factors determining the probability of CSFV introduction (P(CSFV)). As this model contains many uncertain input parameters, sensitivity analysis was used to indicate which of these parameters influence model results most. Group screening combined with the statistical techniques of design of experiments and meta-modeling was applied to detect the most important uncertain input parameters among a total of 257 parameters. The response variable chosen was the annual P(CSFV) into the Netherlands. Only 128 scenario calculations were needed to specify the final meta-model. A consecutive one-at-a-time sensitivity analysis was performed with the main effects of this meta-model to explore their impact on the ranking of risk factors contributing most to the annual P(CSFV). The results indicated that model outcome is most sensitive to the uncertain input parameters concerning the expected number of classical swine fever epidemics in Germany, Belgium, and the United Kingdom and the probability that CSFV survives in an empty livestock truck traveling over a distance of 0-900 km.     

The Service Role of Outside Boards in High Tech Start‐ups: A Resource Dependency Perspective

Despite growing interest in the board of directors of entrepreneurial firms, the role of outside board members in high tech start‐ups has been largely neglected. This dearth of research is surprising since the high level of resource dependency these ventures face is likely to heighten the potential contribution outside board members can make. We argue that, for high tech start‐ups, the service role the board plays will be crucial in overcoming resource dependencies. In contrast to existing studies that tie the outside boards’ servicing role to board characteristics, we propose that greater attention needs to be paid to the resource profile of the venture. Building on resource dependency theory, we find that the extent to which the outside board members fulfil a service role is dependent on the initial human, financial and technological resource base of the entrepreneurial venture. Specifically, we find that ventures with less diversified teams, teams with lower levels of R&D experience and higher levels of financial experience and ventures earlier in the technological development process receive higher levels of support from the outside board.     

Choosing Whether to Buy or Make: The Contracting Out of Employment Reintegration Services by Dutch Municipalities

The Western welfare states are under reform. An important part of these reforms is the introduction of market type mechanisms for the deliverance of public services. Over the years, many countries have chosen to contract out employment reintegration services. The underlying notion of contracting out is the belief that the introduction of market elements in the production of public services increases effectiveness and efficiency. In addition to the cost benefit argument for contracting out public services, ideology is often brought forward as an important factor explaining why public services are provided in‐house. In this article, we analyze to what extent cost benefit arguments and ideology affect the make or buy decision of Dutch municipalities. The Dutch employment reintegration market poses an interesting case in point since Dutch municipalities have the option to either provide employment reintegration services themselves or to buy services on the market. Our analysis shows that cost benefit arguments do not play a role in the make or buy decision of Dutch municipalities. Ideology, however, does. Municipalities that adhere to the principles of New Public Management more often opt to buy employment reintegration services on the market. Also the outcomes of municipal elections have been found to be of importance – left‐wing municipalities more often choose in‐house service provision.
