Hospice organizations are assailed by stiff competition, ever-rising costs, limited funding, and policy changes. Do such pressures stifle the high quality of care these organizations strive to provide? As a case-in-point, we draw from the mid-1990s accounts of caregivers at a nonprofit hospice in a Midwestern city in the United States. We maintain that economic pressures drive organizational restructuring, which then weakens working conditions and, thereby, weakens the staff-client relationship. We discuss effects upon worker behaviors, the worker-client relationship, and client care. This ethnographic case study signals the need to closely examine the threats that current economic and organizational pressures in the United States may pose to the quality of hospice care. 相似文献

In industrial purchasing contexts firms often procure a set of products from the same suppliers to benefit from economies of scale and scope. These products are often at different stages of their respective product life cycles (PLCs). Firms consider multiple criteria in purchasing such products, and the relative importance of these criteria varies depending on the PLC stage of a given product. Therefore, a firm should select suppliers and choose sourcing arrangements such that product requirements across multiple criteria are satisfied over time. The extant models in sourcing literature for evaluating and selecting suppliers for a portfolio of products have not considered this important and practical issue faced by firms. This article proposes a mathematical model that effectively addresses this issue and contributes to the sourcing literature by demonstrating an approach for optimally selecting suppliers and supplier bids given the relative importance of multiple criteria across multiple products over their PLC. The application of the model on a hypothetical data set illustrates the strategic and tactical significance of such considerations. 相似文献

Consider the problem of partitioning n nonnegative numbers into p parts, where part i can be assigned ni numbers with ni lying in a given range. The goal is to maximize a Schur convex function F whose ith argument is the sum of numbers assigned to part i.
The shape of a partition is the vector consisting of the sizes of its parts, further, a shape (without referring to a particular
partition) is a vector of nonnegative integers (n1,..., np) which sum to n. A partition is called size-consecutive if there is a ranking of the parts which is consistent with their sizes, and all
elements in a higher-ranked part exceed all elements in the lower-ranked part. We demonstrate that one can restrict attention
to size-consecutive partitions with shapes that are nonmajorized, we study these shapes, bound their numbers and develop algorithms
to enumerate them. Our study extends the analysis of a previous paper by Hwang and Rothblum which discussed the above problem
assuming the existence of a majorizing shape.

Deliberations are underway to utilize increasingly radical technological options to help address climate change and stabilize the climatic system. Collectively, these options are often referred to as “climate geoengineering.” Deployment of such options, however, can create wicked tradeoffs in governance and require adaptive forms of risk management. In this study, we utilize a large and novel set of qualitative expert interview data to more deeply and systematically explore the types of risk–risk tradeoffs that may emerge from the use of 20 different climate geoengineering options, 10 that focus on carbon dioxide or greenhouse gas removal, and 10 that focus on solar radiation management and reflecting sunlight. We specifically consider: What risks does the deployment of these options entail? What types of tradeoffs may emerge through their deployment? We apply a framework that clusters risk–risk tradeoffs into institutional and governance, technological and environmental, and behavioral and temporal dimensions. In doing so, we offer a more complete inventory of risk–risk tradeoffs than those currently available within the respective risk-assessment, energy-systems, and climate-change literatures, and we also point the way toward future research gaps concerning policy, deployment, and risk management. 相似文献

Voice mechanisms in organizations provide an opportunity for employees to have a say about their work. As new digital mechanisms, such as social media (SM), are being increasingly adopted by organizations for knowledge sharing, employee engagement and general communication, it is important to consider the extent to which SM may facilitate employee voice. The limited attempts to examine SM and employee voice have mostly focused on identifying the contextual factors that could promote constructive voice on SM. The extant literature does not explore how SM features may (or may not) facilitate all types of voice, such as those which promote employee interests. Adopting an affordance lens, this paper answers the call of voice scholars to explore the potential of SM as a voice mechanism by discussing the perceived value of different SM features for different types of employee voice content. The paper brings together SM and voice literature and explores how different SM affordances may potentially facilitate certain voice content more so over others. In doing so, future directions for research of voice on SM are also discussed. 相似文献

In a series of 2 papers, Kang, Du and Tian solved the existence problem for G-decomposition of λ
K
n
when G is any simple graph with 6 vertices and 7 edges, except when G is the graph T=K
4∪K
2. Notice that a T-decomposition can be considered to be a Pairwise Balanced Design in which each block of size 4 has been matched to a block
of size 2. In this paper we remove this exception for all λ≥2. The case when λ=1 is also addressed.

Considerations on the design of a professional education of counselorsSome of the recently published articles about supervision-professionalizing are reflecting only sociological or psychological conceptions in order to describe and analyze professionality. In this article the authors discuss some of the mostly neglected points of view out of pedagogic and microsociologic professionalization-research (professional self, researching attitude). The existing requests of competence for supervisors are examined in order to test their teaching ability. Furthermore the content designs and didactic strategies for future counselor’s education are considered. 相似文献

Zusammenfassung Der Beitrag erkl?rt einerseits die Notwendigkeit eines durch Gesetz geregelten Verfahrens zur Insolvenzabwicklung mittels
betriebswirtschaftlicher Grundlagentheorien. Andererseits werden dieselben Grundlagentheorien genutzt, um die unterschiedlichen
sich ver?ndernden Machtstrukturen, die oft gegens?tzlichen Interessen von Stakeholdern, die Kosten des Insolvenzprozesses
sowie deren Dynamik im Rahmen des vierphasigen Insolvenzprozesses (vor Insolvenzanmeldung, nach Antragstellung, nach Er?ffnung,
nach Abschluss des Verfahrens) eines Not leidenden Unternehmens besser veranschaulichen zu k?nnen. Der besondere Schwerpunkt
wird hierbei auf das Verfahren in Eigenverwaltung, das hei?t mit eigenem Management, gelegt.
The bankruptcy process and the self-administration in the bankruptcy proceedings
Summary This article explains on one hand the necessity of a legally fixed process for the bankruptcy proceedings with basic economic theories. On the other hand, the same theories are used to demonstrate the changing power structures, the often different interests of stakeholders, the costs of the bankruptcy proceedings as well as its dynamics during the four bankruptcy phases (before the filing, after the filing, after opening and after closing) of the bankruptcy process. The focus of this article lies hereby on bankruptcy proceedings in self-administration which means that the management stays on duty.
