Benefits of using hybrid business models within a supply chain

Today's competition between supply chains (SC) requires optimized strategies in order to satisfy customers’ demands. The business models used by the SC members play a big role in this delivery of value to the customer. From here the notion that a mismatch between the intended market and the business model used to address it translates into a poor SC performance. As real-life business environments have become really complex, SC members have been forced to use hybrid business models (that is, the integration of features of two different business models). A review of the literature in the area of supply chain management shows that past research have not paid much attention to this issue. The objective of this paper is to quantitatively evaluate the influence these hybrid business models have on the SC performance. For this purpose, a system dynamics (SD) simulation model is developed and tested under different operational conditions, so conclusions can be derived regarding the benefits of the use of hybrid business models.     

一种改进的不限重传次数的HARQ重传方案

为了保证数据在无线衰落信道条件下的可靠传输,产生了联合前向纠错编码(FEC)与自动请求重传(ARQ)的混合ARQ(HARQ)技术。HARQ有多种重传方案,本文针对HARQ的无限次重传方案进行了研究,提出了一种改进的基于RCPT码的HARQ重传方案,并分别与传统RCPT-HARQ方案在瑞利快衰落、慢衰落信道下进行仿真比较,仿真结果显示出改进方案在慢衰落信道条件下获得了更高的通过率。     

Can brand image move upwards after Sideways? A strategic approach to brand placements

In today's environment of fragmented mass media and popular technologies, such as DVR and TiVo, it is increasingly challenging for marketers to obtain quality face time with audiences. As more customers try to avoid advertisements, there has been growth in brand placement: the practice of integrating brands into entertainment media, particularly television and film. Brand placement engages the audience, limits viewers’ ability to ignore commercial messages, and even impacts purchase behavior—as evidenced by the surge in Blackstone pinot noir wine sales after the brand's placement in the movie Sideways. Despite the prevalence of this practice, however, the industry often operates in a somewhat unfocused manner. In this article, we draw from academic literature and industry publications, offer insight regarding the growing popularity of brand placements, and suggest a specific set of guidelines to enhance the efficacy of placements in accomplishing a brand's marketing objectives.     

Organizing professionals and their impact on performance: the case of public health doctors in the Italian SSN

ABSTRACT

Hybrid professional managers have been associated with improvements in the performance of public sector organizations. However, less attention has been given to differences within this category. Drawing on board human capital theory, we focus on an emerging group of ‘organizing professionals’ with earlier and deeper exposure to management training and education: generalist clinical hybrids drawn from public health in the Italian healthcare system. Specifically, we investigate the impact that these hybrid hospital CEOs have on organizational performance in comparison with other backgrounds. The results indicate that this form of generalist hybrid professionalism has distinct, if not dramatic, consequences for performance.     

Managing Multiple Institutional Logics and the Use of Accounting: Insights from a German Higher Education Institution

This paper examines the use of accounting in managing the co-existence of different institutional logics in a German higher education institution (HEI), and its impact on the HEI. The study is of particular interest as the HEI analyzed pursued its own corporatization through a re-organization from a state into a foundation university. We show that this corporatization through the adoption of new public management related ideas leads to institutional complexity arising from the co-existence of extant state and emergent business logics. Our study suggests that HEIs may deploy particular accounting practices shaped by business logic only superficially, so as to satisfy stakeholders such as governmental authorities in order to enhance their legitimacy following a self-imposed reform, while the operation of the HEI remains rooted in state logic. Specifically, the findings suggest that in the case of actual changes to the budgetary process arising through the corporatization and an emergent logic, failure to replace abandoned accounting practices shaped by a previously dominant logic with equivalent practices adhering to either extant or emerging logic(s), may put the organization at risk. Overall, our study contributes to a better understanding of the dangers of an organizational response to institutional complexity, referred to as reactive decoupling, in the management of institutional complexity and points to its negative impact on organizations' hybridization capability.     

A hybrid approach to international market selection: The case of impact investing organizations

Social enterprises are hybrid organizations that concurrently pursue social and economic goals and hence are mid-way between conventional capitalistic firms and non-profit organizations. Many social enterprises are becoming international; delivering services across borders. With the objective of understanding the internationalization of these unconventional organizations, this paper examines their international market selection decision based on host countries’ macroeconomic conditions. Generally, we hypothesize that the international market selection decision of social enterprises is tied to their hybridity, an overarching characteristic that sets them apart from other types of organizations. We build an original dataset with information on 41 European and North American impact investing organizations and 153 developing countries. Largely, our findings support the hypothesis, suggesting that social enterprises operate in foreign countries that offer a desirable balance between their social and financial goals. However, they avoid contexts with high country risk, factors that could cause a shortfall in expected returns.     

Integrating means-end chains and the Kano model to understand tourists’ cognitive structure toward leisure and recreational resources of suburban-mountains

This study integrates the means-end chain (MEC) theory and Kano model to better understand tourists’ inner thinking toward the leisure and recreation resources of suburban-mountains, and help in prioritizing decisions on mountain recreational resource management for the government and related managerial officers. A total of 303 valid responses from individuals aged over 50 years with the habit of hiking in this area at least once a week were collected for MEC and Kano analyses. The results of the hybrid hierarchical value map show that one-dimensional attributes (i.e. “water resources, “providing cultural and educational facilities,” “providing hiking trails,” “providing scenic overlook and pavilion,” “providing guardrails,” and “providing resting area”) are the priorities that the government and managers should pay the most attention to for the elderly people hiking the suburban-mountains. By following the same deduction process proposed in this study, the rest of the one-dimensional consequences and values can be depicted. Finally, the theoretical and managerial implications as well as the limitations of this work are also provided. This study can not only enrich the theoretical development of MEC theory, but also provide the government with valuable information to enhance the leisure and recreation resources of suburban-mountain areas for elderly tourists.
