Applications of business analytics in healthcare

The American healthcare system is at a crossroads, and analytics, as an organizational skill, figures to play a pivotal role in its future. As more healthcare systems capture information electronically and begin to collect more novel forms of data, such as human DNA, how will we leverage these resources and use them to improve human health at a manageable cost? In this article, we argue that analytics will play a fundamental role in the transformation of the American healthcare system. However, there are numerous challenges to the application and use of analytics: the lack of data standards, barriers to the collection of high-quality data, and a shortage of qualified personnel to conduct such analyses. There are also multiple managerial issues, such as how to get end users of electronic data to employ it consistently to improve healthcare delivery and how to manage the public reporting and sharing of data. In this article, we explore applications of analytics in healthcare, barriers and facilitators to its widespread adoption, and ways in which analytics can help us achieve the goals of the modern healthcare system: high-quality, responsive, affordable, and efficient care.     

Non-fatal violence-related injuries in Kingston,Jamaica: a preventable drain on resources

Using data for a one-year period from the Kingston Public Hospital (KPH) in Jamaica, we describe patterns of non-fatal violence-related injuries, and carry out simulation analysis to estimate rates of hospital admission under various injury reduction scenarios, and the potential savings that can be realized by reducing violent crimes. In this period there were 6107 registered violence-related visits to the KPH representing 11.5% of all recorded visits. Of these 16.6% (1001) were admitted. The most common methods of inflicting injury was by stabbing (52.1%), blunt injuries (37.9%) and gunshot wounds (7.3%). Multivariate analyses indicated that gunshot injuries, stab injuries, being male between the ages of 15 and 44 years, receiving the injury in November or December, and being injured by a stranger or unknown assailant, were significant correlates of a higher probability of admission. Simulation analysis with various injury reduction scenarios indicated decreases in the probability of admission ranging from 12% to 44%, with estimated savings of up to 31% of the annual supplies budget of KPH.

Value Congruence and Charismatic Leadership in CEO–Top Manager Relationships: An Empirical Investigation

Although charismatic leadership theorists have long argued that leader–follower value congruence plays a central role in the development of charismatic relationships, few studies have tested this proposition. Using data from two studies involving a total of 329 CEOs and 1807 members of their top management teams, we tested the hypothesis that value congruence between leaders and their followers is empirically linked to follower perceptions of the charisma of their leader. Consistent with a relational perspective on charismatic leadership, strong support was found for the hypothesis that perceived value congruence between leaders (CEOs) and their followers (members of their top management teams) is positively related to follower perceptions of the degree of charisma possessed by the leader. Conversely, only limited support was found for the hypothesis that actual value congruence is linked to perceptions of charismatic leadership. Implications of these findings for research and practice are discussed.     

Can Nature Drive Economic Growth?

The conditions that lead to successful economic development are diverse and place sensitive. Recent research supports the notion that there is a correlation between the presence of natural amenities and rural economic development. This case explores the situation of a rural county that is faced with constrained development options as a result of a significant federal footprint on the county's land area. The actions of the federal agencies managing the resources impact the economic vitality of the region. Two issues currently under review challenge the county to think critically about its potential for using nature as an economic development tool.     

The British investor's gains from international portfolio investment

This paper analyses the effects of exchange controls on the ranking of British and overseas investments. A method is developed by which the costs of such controls can be incorporated into return calculations. It is shown that the adjustment of returns for exchange controls significantly alters the rankings of investments. An additional aspect of the paper is to rank domestic and foreign investments by stochastic dominance and compare the derived rankings with mean-variance. Again a significant differences in rankings is identifiable. It is concluded that the exchange rate regime, institutional exchange controls and the entire distribution of returns should be considered in ranking domestic and foreign investments.     

AN EMPIRICAL STUDY OF THE INCREMENTAL PREDICTIVE ABILITY OF BEAVER'S NAIVE OPERATING FLOW MEASURE USING FOUR-STATE ORDINAL MODELS OF FINANCIAL DISTRESS

The purpose of this paper is to determine why net income adjusted for depreciation and amortization (NOF) is a strong predictor of financial distress. This paper develops four-state ordinal financial distress models lagged one, two, and three years before financial distress to test NOF, instead of using dichotomous bankrupt and nonbankrupt models. The results of this paper suggest that NOF is a strong predictor of financial distress because NOF is an alternative measure of economic income, not because NOF is a naive measure of operating cash flow. For this study, NOF is even a better measure of economic income than net income.     

Influence of livelihoods on climate change adaptation for smallholder farmers in the Mekong Delta Vietnam

Farmers in the Vietnamese Mekong Delta face a wide range of climate-related and hydrological factors which threaten rice production. Smallholder farmers must adapt to climate change to sustain rice production as their central and most important livelihood activity. A sample was stratified across agro-ecological areas in the Delta affected by flooding, alluvial soils, acid sulphate soils, and saline water intrusion and by derived farmer typologies. A rural livelihoods approach was used in focus group discussions and in-depth interviews to identify and enumerate enabling and constraining adaptation factors. Smallholders experienced diverse natural hazards such as floods, abnormal rains, high temperatures, water scarcity, and salinity intrusion specific to the agro-ecological areas. Adaptation was constrained by labour shortages, water quality, topography, access to combine harvesters, transportation infrastructure, dryers and household savings. Adaptation was enabled by farming techniques and experience, cooperative groups, water quantity, access to information, and ability to purchase agro-chemicals through credit. Small farmers (< 1?ha) were more constrained than large farmers (> 1?ha) who had an expanded livelihood asset base. A range of policy implications are discussed, but adaptation is not just about technological fixes but requires overall improvements in a range of human, social and financial components.
