日本移动影音的商业模式探析

在移动影音产业既有的成功商业模式之中,日本经验常被提及,其主要经营模式被归类为"免费播放"。一般认为,正是通过"免费播放"这种方式,才能从一开始就顺利实现让消费者对于移动电视由认识、接受到使用的历程。然而,日本移动电视之所以成功,并非完全归功于免费播放,还另有原因。     

Estimating two-stage network Slacks-based inefficiency: An application to Bangladesh banking

This paper studies the performance of nineteen private commercial banks and two government-owned banks in Bangladesh during the period 2005–2008 using a slacks-based inefficiency measure and the directional technology distance function. Performance is measured assuming a black-box production structure and then the black-box is opened and examined using a two stage network production structure. Current period performance in maximizing desirable loans and securities investments and minimizing bad loans depends on how efficiently inputs at one stage of production are transformed into intermediate outputs which are used at a subsequent stage of production. In addition, current period production of the intermediate output is constrained by the amount of non-performing loans that were generated in an earlier period.     

Dispelling stereotypes: promoting disability equality through film

All too often individuals with disabilities in the popular media are portrayed as people to be pitied or super humans to be admired. Film is one important resource that helps form the public’s beliefs and dispositions about people with disabilities. With that in mind a film festival was designed to provide authentic representation of people with disabilities living normal lives so as to help viewers see individuals with disabilities as people first. Part of the effort was to develop a more realistic understanding and appreciation for the lives of individuals with disabilities. Various programs were developed across disciplines to present a wide range of perspectives. Following each viewing filmmakers and faculty led in‐depth discussions about the films. A participant survey indicated the use of film as an effective pedagogical methodology that provided an entertaining and meaningful way to generate discussion and change attitudes about disabilities.     

Narrative Therapy,Eating Disorders and Groups: Enhancing Outcomes in Rural NSW

Abstract

The present paper reports on a study conducted with seven women who identified themselves as experiencing depression as well as an eating disorder and who live in a rural region of northern New South Wales. Self-referred, the women participated in a weekly group for 10 weeks, with a mixture of topics, conducted within a narrative therapy framework. A comparison of pre- and post-group tests demonstrated a reduction in depression scores and eating disorder risk. All women reported a change in daily practices, together with less self-criticism. These findings were supported by a post-group evaluation survey that revealed that externalisation of, and disengagement from, the eating disorder strongly assisted the women to make changes in their daily practices. Although preliminary and short term, the outcomes of the present study indicate that group work conducted within a narrative therapy framework may result in positive changes for women entangled with depression and an eating disorder.     

Auto Therapy: Using Automobiles as Vehicles for Reminiscence With Older Adults

Reminiscence can be beneficial for older adults and contribute to well-being and ego integrity. In this exploratory pilot study, researchers assessed the feasibility and tolerability of a novel reminiscence intervention using automobiles as the focal point. Nineteen older adults (N = 19) were asked to reminisce using photographs of automobiles from across their lifespan. The RE-AIM framework was used to assess the intervention in terms of reach, effectiveness, adoption, implementation, and maintenance. The intervention was well-received, quickly established rapport, and effectively fostered reminiscence. Social workers may find this intervention useful in helping older adults to explore their lives.     

The Legacy of ‘Solidarity’: Class,Democracy, Culture and Subjectivity in the Polish Social Movement

The sociological debate on the nature of Solidarity, and its legacy for social mobilization in today's Poland, are assessed through secondary research as well as primary research on Polish social movements in 1995–2001. The three classic interpretations of Solidarity (class, democracy and nation) are discussed, and two conclusions are reached to overcome the ‘class versus intellectuals’ dispute. First, against cultural and political interpretations, a class interpretation is appropriate although not exclusive and not in a classic Marxist sense. Second, a fourth element, subjectivity, needs to be added to understand the rare combination of egalitarianism and individualism in Solidarity. The class and the subjective elements derive from the double nature of Polish society: industrial and ‘vocationally’ (not factually) totalitarian. The implication is that social mobilization in Poland can be expected primarily in labour activism and marginal cultural movements.     

Single machine batch scheduling with release times

Motivated by a high-throughput logging system, we investigate the single machine scheduling problem with batching, where jobs have release times and processing times, and batches require a setup time. Our objective is to minimize the total flow time, in the online setting. For the online problem where all jobs have identical processing times, we propose a 2-competitive algorithm and we prove a corresponding lower bound. Moreover, we show that if jobs with arbitrary processing times can be processed in any order, any online algorithm has a linear competitive ratio in the worst case. A preliminary version of a part of this paper was presented at the 31st International Symposium on Mathematical Foundations of Computer Science (MFCS 2006).

Optimal replacement strategies in network infrastructures under quality penalties

As a consequence of liberalization, electric utilities have developed different asset management strategies with the aim of reducing total maintenance costs by prolonging replacement cycles. A cost-minimizing network operator has to optimize the trade-off between costs for early replacement and quality penalties he faces in the case of outages (due to a resulting higher number of failures). The basic purpose of this paper is to identify the optimal decisions for a network operator under output-based quality regulation and to determine the main drivers for his decisions. In order to derive general insights, an analytical framework is chosen for this paper. This work builds on the foundations of optimal maintenance and replacement strategies as developed across Operations Research, Production Economics and Engineering Production Theory. As main results we are able to analytically derive optimal replacement strategies for network components depending on the characteristics of their failure distributions linked to the equipment’s cost, respective replacement cost, and quality penalties.     

Poll results: doctors' disruptive behavior disturbs physician leaders

Results of ACPE's 2004 Physician Behavior Survey show that physician executives face deep frustrations when forced to tackle the thorny issue of disruptive behavior by fellow physicians.
