Peeling Back the Onion Competitive Advantage Through People: Test of a Causal Model
Proponents of the resource-based view (RBV) of the firm have identified human resource management (HRM) and human capital as organizational resources that can contribute to sustainable competitive success. A number of empirical studies have documented the relationship between systems of human resource policies and practices and firm performance. The mechanisms by which HRM leads to firm performance, however, remain largely unexplored. In this study, we explore the pathways leading from HRM to firm performance. Specifically, we use structural equation modeling to test a model positing a set of causal relationships between high performance work systems (HPWS), employee retention, workforce productivity and firm market value. Within a set of manufacturing firms, results indicate the primary impact of HPWS on productivity and market value is through its influence on employee retention
HRM and Firm Productivity: Does Industry Matter?
Recent years have witnessed burgeoning interest in the degree to which human resource systems contribute to organizational effectiveness. We argue that extant research has not fully considered important contextual conditions which moderate the efficacy of these practices. Specifically, we invoke a contingency perspective in proposing that industry characteristics affect the relative importance and value of high performance work practices (HPWPs). We test this proposition on a sample of non-diversified manufacturing firms. After controlling for the influence of a number of other factors, study findings support the argument that industry characteristics moderate the influence of HPWPs on firm productivity. Specifically, the impact of a system of HPWPs on firm productivity is significantly influenced by the industry conditions of capital intensity, growth and differentiation
Adapting clinical guidelines to take account of multimorbidity
Most people with a chronic condition have multimorbidity, but clinical guidelines almost entirely focus on single conditions. It will never be possible to have good evidence for every possible combination of conditions, but guidelines could be made more useful for people with multimorbidity if they were delivered in a format that brought together relevant recommendations for different chronic conditions and identified synergies, cautions, and outright contradictions. We highlight the problem that multimorbidity poses to clinicians and patients using guidelines for single conditions and propose ways of making them more useful for people with multimorbidity

Moving infrastructure benefits beyond projects and programmes
Recent research confirms the growing limitation of infrastructure projects and programmes to deliver long-term benefits to society. A more holistic, system-level approach to infrastructure delivery and management is needed, say Carron Blom and Peter Guthrie from the University of Cambridge.

Identifying the needs of communities in rural Uganda: A method for determining the ‘User-Perceived Value’ of rural electrification initiatives
This research paper describes the use of a ‘User-Perceived Value Game’ to explore the value of development initiatives as perceived by villagers in 119 interview settings in seven Ugandan villages. Based on the findings from the game, a ‘User-Perceived Value Framework’ is developed, consisting of 64 value categories. This is depicted graphically as a ‘User-Perceived Value Wheel’ supported by a ‘Key Phrase Wheel’, both can be modified using computer-assisted software developed by one of the authors. The aim is to understand the reasons why something is perceived by the end user to be important. This will lead to an improved understanding of how a development initiative can be better tailored for lower-income markets. The initiative can then be marketed appropriately, which will result in user acceptance because the initiative will be perceived to have personal value to the user and therefore the user will care for its upkeep. The paper concludes with a brief application of the ‘User-Perceived Value Wheel’ to demonstrate how this tool can be used to better understand the true sustainability drivers behind rural electrification development initiatives.Engineering and Physical Sciences Research Council (Grant ID: EP/K503009/1), Qualcomm European Research Studentships in Technology (Grant ID: 1068
The Role of Medications in Predicting Activity Restriction Due to a Fear of Falling
Objectives: To examine the role of medication use and other factors in predicting activity restriction due to a fear of falling (AR/FF). Methods: Older adults were assessed twice with the interRAI Community Health Assessment and the Berg Balance Scale (BBS). The main outcome was limiting going outdoors due to an AR/FF. Medications were recorded by trained assessors. Results: Participants (n=441) had a mean age of 80.3 (sd=7.1) years, most were aged 65+ (96.8%) and 29.3% reported activity restriction. Taking nervous system active or cardiovascular medications was associated with AR/FF. In a multivariate model, the main predictors were having 3+ comorbid health conditions, lower (i.e., worse) scores on the BBS, having difficulty with climbing stairs, and having a visual impairment. Discussion: Modifiable risk factors, related to functional impairments, such as difficulties with balance and vision, appear to be more important predictors than medications
The health and well-being of older adults with dual sensory impairment (DSI) in four countries
Objectives
Dual sensory impairment (DSI) is a combination of vision and hearing impairments that represents a unique disability affecting all aspects of a person’s life. The rates of DSI are expected to increase due to population aging, yet little is known about DSI among older adults (65+). The prevalence of DSI and client characteristics were examined among two groups, namely, older adults receiving home care services or those residing in a long-term care (LTC) facility in four countries (Canada, US, Finland, Belgium). Methods
Existing data, using an interRAI assessment, were analyzed to compare older adults with DSI to all others across demographic characteristics, functional and psychosocial outcomes. Results
In home care, the prevalence of DSI across the four countries ranged from 13.4% to 24.6%; in LTC facilities, it ranged from 9.7% to 33.9%. Clients with DSI were more likely to be 85+, have moderate/severe cognitive impairment, impairments in activities of daily living, and have communication difficulties. Among residents of LTC facilities, individuals with DSI were more likely to be 85+ and more likely have a diagnosis of Alzheimer’s disease. Having DSI increased the likelihood of depression in both care settings, but after adjusting for other factors, it remained significant only in the home care sample. Conclusions
While the prevalence of DSI cross nationally is similar to that of other illnesses such as diabetes, depression, and Alzheimer’s disease, we have a limited understanding of its affects among older adults. Raising awareness of this unique disability is imperative to insure that individuals receive the necessary rehabilitation and supportive services to improve their level of independence and quality of life
