A continuous sampling plan using CUSUMs

A Continuous Sampling Plan, CSP-CUSUM, is proposed based on the use of Cumulative Sums (CUSUMs) for deciding when to switch between the phases of sampling inspection and 100% inspection. The Geometric CUSUM, also termed the Run-length CUSUM, is chosen for this purpose, and two separate CUSUMs are to be operated, one for each inspection phase. The conventional measures of performance for CSPs such as average outgoing quality, average fraction inspected, and average proportion passed under sampling inspection are evaluated for CSP-CUSUM, and comparisons with some standard CSPs are presented. An additional performance-measure, Average Cycle Length, is proposed. A table is provided to aid the choice of parameters for the operation of CSP-CUSUM. It is recommended that a Geometric CUSUM control chart be maintained in parallel with CSP-CUSUM to detect significant upward shifts in the incoming fraction defective.     

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.

     

The Role of Criminal Social Identity in the Relationship between Criminal Friends and Criminal Thinking Style within a Sample of Recidivistic Prisoners

Previous research suggests a direct relationship between criminal friends and criminal thinking style; however, social identity theory proposes that identity mediates the impact of social group members on development of thinking styles. This research project is the first attempt to empirically test the mediating role of criminal social identity in the development of criminal thinking styles within a recidivistic prison sample (N = 312). The structural equation model of criminal thinking style presented and tested in this study supports the central predictions of social identity theory, with findings demonstrating an indirect effect of antisocial friend associations on criminal thinking through in-group affect and in-group ties with criminal in-group members that reflect two of three dimensions of the measure of criminal social identity applied in the current study. Further implications in relation to theory and previous studies are discussed.     

The RL2 chart versus the np chart for detecting upward shifts in fraction defective

The use of the np chart for monitoring fraction-defective is well-established, but there are a number of relatively simple alternatives based on run-lengths of conforming items. Here, the RL₂ chart, based on the moving sum of two successive conforming run-lengths, is investigated in order to provide SPC practitioners with clear-cut guidance on the comparative performance of these competing charts. Both sampling inspection and 100% inspection are considered here, and it is shown that the RL₂ chart can often be considerably more efficient than the np chart, but the comparative performance depends on the false-alarm rate used for the comparison. Graphs to aid parameter-choice for the RL₂ chart are also provided.     

Economic Attitudes and Responses to Siting Hazardous Waste Facilities in Rural Utah1

Abstract The siting of hazardous waste facilities has become a critical problem for the United States. Many western states are plagued with proposals to site such facilities. While the host communities appear to be typical western rural communities, responses to siting hazardous waste facilities vary. Previous research suggests that key variables in predicting responses are the anticipation of economic benefits and the perception of risk. This paper proposes that response to siting hazardous industries in rural Utah is not only a result of these key variables but also residents' perception of the local economy. Results from ethnographic and survey data from three rural communities in Utah indicate that the anticipation of economic benefits and perception of risk were strongly associated with response to a proposal, and that residents of communities with poorer local economies were more likely to support siting a hazardous waste facility locally.     

Implementing a marketing action programme for AIB group

In 1986, with the appointment of Group Chief Executive Mr. G. B. Scanlan, Allied Irish Banks Group recognized the need to respond to a wide range of changes in the competitiveness of its markets, the regulatory environment and the demands of its customers. Radical change was necessary in the internal attitudes and values, formed for the majority of staff by its clearing bank history. AIB decided on a group wide development programme with the objective of building a unified organization, market focused and responsive to customer needs. The programme, communicated under the title MAP (Marketing Action Programme) had an initial 5 year horizon (1989–1992). A series of major initiatives under the MAP banner were designed to achieve significant shift in organizational values and culture.     

Rural Victorian service provider responses to the National Disability Insurance Scheme

The National Disability Insurance Scheme (NDIS) has transformed the nature of funding available to health and human service organisations to provide services to people with disability in Australia. However, there is relatively scant literature on the rural implementation of the NDIS, particularly how rural NDIS service providers are affected by the NDIS. Researchers conducted semi-structured interviews with 20 health professionals employed by rural providers, and analysed data using rural and remote health and organisational change frameworks to understand how rural providers were impacted by and responded to the NDIS. The findings suggest rural providers were impacted to differing extents and responded to the NDIS in different ways. Participants reported that disability and community health services were affected more than hospitals and private allied health practices. Impacted rural providers responded by changing the nature and types of services, service processes and their workforce, and redefining organisational characteristics. Impacted rural providers may require additional support to continue providing services, and those less impacted may require other incentives to better engage with the NDIS. Rural proofing of NDIS policy could reveal suitable supports and incentives to ensure rural people with disability can access required services.
