Implementing Cost Control in Health Care: Strategies Driven by an Organizational Systems Approach

In this paper, we offer a systems approach to assist health care organizations in their cost-containment efforts. A general model of the organization which specifies the various components of this approach is offered. Each system—technology, structure, psychosocial, managerial, and cultural—is linked to illustrative selected actions designed to improve cost performance. In our view, the key to successful interventions to contain costs lies in careful consideration of both the direct and interactive impacts on all systems of the health care organization. A case example of an Academic Medical Center's effort to curtail costs illustrates both the model and the sample actions.     

Recent Results on Constructing Boolean Functions with (Potentially) Optimal Algebraic Immunity Based on Decompositions of Finite Fields

Boolean functions with optimal algebraic immunity (OAI functions) are important cryptographic primitives in the design of stream ciphers. During the past decade, a lot of work has been done on constructing such functions, among which mathematics, especially finite fields, play an important role. Notably, the approach based on decompositions of additive or multiplicative groups of finite fields turns out to be a very successful one in constructing OAI functions, where some original ideas are contributed by Tu and Deng (2012), Tang, et al. (2017), and Lou, et al. (2015). Motivated by their pioneering work, the authors and their collaborators have done a series of work, obtaining some more general constructions of OAI functions based on decompositions of finite fields. In this survey article, the authors review our work in this field in the past few years, illustrating the ideas for the step-by-step generalizations of previous constructions and recalling several new observations on a combinatorial conjecture on binary strings known as the Tu-Deng conjecture. In fact, the authors have obtained some variants or more general forms of Tu-Deng conjecture, and the optimal algebraic immunity of certain classes of functions we constructed is based on these conjectures.

Organization Change in a University Hospital: A Six Year Evaluation Report of the HORIZONS Project

Many health care organizations are currently engaged in changing the design of their health care services delivery system. The issues of cost containment, quality, and access are prominent. This paper reports on the impact of the implementation of a new organization design at one university hospital. The organization change effort (named HORIZONS) was a five year project funded in part by the Robert Wood Johnson Foundation and the Pew Charitable Trusts. In a changing health care environment, the project was undertaken with three goals in mind: (1) to maintain and enhance quality of patient care; (2) to improve the quality of working life; and (3) to accomplish this in a budget neutral manner. Initiated as a program to strengthen hospital nursing, the project became a patient-focused redesign effort encompassing both clinical and administrative affairs. The core ideas of the project approach included systems thinking, interactive planning and idealized design. This evaluation reports on the project's progress after six years.     

GreenCommute: An Influence-Aware Persuasive Recommendation Approach for Public-Friendly Commute Options

Negative impacts produced by transportation sector have increased in parallel with the increase of urban mobility. In this paper, we introduce GreenCommute, a novel recommendation system which can facilitate commuters to take public friendly commute options, while provide support to alleviate the external cost in society, such as traffic pollution, congestion and accidents. In the meanwhile, a rewarding mechanism for persuading commuters is embedded in the proposed approach for balancing the conflict between personal needs and social aims. The allocation of reward values also takes users’ influential degrees in the social network into consideration. Experimental results show that the GreenCommute can promote public friendly commute options more effectively in comparison to the traditional recommendation system.

ORGANIZATIONAL LEARNING AND VENDOR SUPPORT QUALITY BY THE USAGE OF APPLICATION SOFTWARE PACKAGES： A STUDY OF ASIAN ENTREPRENEURS

In this paper we study how organizational learning impacts organizational behavior, and howvendor support quality enhances product adoption and usage behavior.These constructs were verifiedusing Application Software Packages(ASP)-a prewritten, precoded, commercially available set ofprograms that eliminates the need for individuals or organizations to write their own softwareprograms for certain functions. The relationship between ASP usage, usage outcomes and useprocesses were also investigated. Two hundred and ninety-five Chinese, Indian, and Malayentrepreneurships were studied. It was found that usage outcome strongly determines usage, while useprocess has only an indirect relationship (via outcome) on usage. The impact of organizational learningand vendor service quality on usage, usage outcome, and use process were robust. Theoretical andpractical implications of the research are discussed.

poCDIO: A Methodological Proposal for Promoting Active Participation in Social Engineering Projects

Currently, both public and private organizations, as well as the academic milieu are developing social projects in order to strengthen and improve the quality of life. This is the case of Engineers Without Borders Colombia (ISFCOL for its Spanish acronym), an organization formed by engineering teachers and students from Los Andes University and the Minuto de Dios University Corporation that develops engineering projects within communities in order to solve environmental and social problems. However, based in the group’s experience, a problem has been identified regarding the absence of a methodology that promotes the active and effective participation of all the parties involved, which can prevent the accomplishment of otherwise technically viable, socially responsible, and sustainable projects. Looking to address this issue, this paper presents a methodological proposal for promoting the active participation of all the parties involved in engineering projects that have a social impact. The proposal is structured following the stages of the oCDIO context (Observe, Conceive, Design, Implement and Operate), and is successfully applied during the development of an ISFCOL project in which the participation of all the parties involved becomes a key element for the effective accomplishment of the engineering proposal and for the generation of socially responsible impacts. Namely, the project “Fortalecimiento Negocios Verdes Comunitarios Provincia del Guavio” (Community Green Businesses Strengthening in the Guavio Province) whose main goal was to strengthen the innovation and the entrepreneurship in the Guavio region communities, consolidating thus an active participation network of 400 members made up by small entrepreneurs and students from rural communities close to the city of Bogota and from higher education institutions.
