The devolution of HR to the line: Implications for perceptions of people management effectiveness

The devolution of human resource responsibilities from human resource managers to line managers is both a growing and global trend. A number of authors has suggested that there are positive as well as negative consequences of devolution. The current study conducted a survey of US human resource managers to explore the effect of devolution on human resource managers' perceptions of people management effectiveness in their organizations. Results revealed a positive effect of devolution on perceived people management effectiveness. However, this effect was qualified by an interaction between devolution and line support. Contrary to expectation, this interaction revealed that providing line managers with training and support for their human resource responsibilities had a greater positive impact on perceived effectiveness in organizations that had not devolved (non devolvers) compared to those that had (devolvers).     

销售要找到＂关键人物＂

作为一个商业新手,你不得不为每一笔销售而拼尽全力。如果情况变成有一群稳定的、连续的、热情的准客户群主动找上门来,是不是很美妙呢？来自于客户和其他企业家的推荐能帮你把你的新公司列入备选名单。但要想达到上述效果,只是散发名片、在家人和朋友中间口口相传是远远不够的。你必须与影响者（influencers）建立关系那些有能力影响对你公司看法的人、或那些和你的最佳准客户一对一地打交道时能进行直接推荐的人。     

Health Information Technology and Financing's Next Frontier: The Potential of Medical Banking

Calls to action for widespread adoption of electronic health records have come from a broad spectrum of the private and public sectors. The problem, to date, is not that information does not exist, as much as that the data have not been organized around the patient. An integrated Personal Health Record is a patient- or family-centered technology designed to capture not only the contacts with health care providers, but also personal information on insurance, diet, and personal preferences that a physician's health record will not capture. Medical banking, based on a new technology platform called the Integrated Health Card, is emerging as a solution to the problem of collecting and combining information from the electronic health record with personal health information. It may also be the only way for fledging health savings accounts to enable the price and quality transparency of the medical market that has been called for repeatedly in this decade. In analyzing the political and patient applications of widespread adoption of this new innovation, the positive contributions to social welfare are very likely to outweigh the negative.     

Currency returns, market regimes and behavioral biases

Covered interest rate parity assumes that there is no risk premium on the hedged returns on currencies. However, empirical evidence indicates that risk premiums are not identically zero, and this is referred to as the forward premium puzzle. We show that there exist market regimes, within which behavioral biases affect decisions, and a type of parity holds within regimes. The foreign exchange market switches between regimes where there is a premium. This paper presents various tests for the hypotheses of currency regimes and regime dependent risk premiums. Based on the existence of regimes, a diversified currency portfolio is created with a mean-variance criterion. Using the Federal Exchange Rate Index as a proxy for the currency benchmark and the U.S. T-Bill as the risk free asset, the similarity between the benchmarks and the implied equilibrium hedged and unhedged portfolios provides evidence for regimes and decision bias. Within each regime interest rate parity is appropriate for modeling currency returns.     

Countering Service Information Challenges in the Internet of Services

Business Webs apply the idea of value networks to the WWW. The underlying delivery platform is commonly referred to as the Internet of Services and will certainly have to deal with a great variety and amount of information about services along several service information dimensions. As soon as brokerage, discovery, or community feedback parts are decentralized, there emerge a number of service information challenges (modeling the information in a holistic way, documentation, interlinkage, tool interoperability, distributed querying, inconsistent information, and cooperation of different stakeholders). In this paper, we propose to counter such service information challenges by two artifacts. First, we contribute a Service Ontology based on a sound and rigid foundational ontology. The Service Ontology provides a holistic and consistent way of capturing service information. We apply the recommendations of the W3C Semantic Web Activity whose recent standardization has already opened new possibilities for tool interoperability, interlinkage of information, and distributed querying on the web. However, building and prescribing an ontology in standardized languages is not enough to address all service information challenges. Therefore, as a second contribution, we provide a method around the ontology including a governance framework, guidelines for applying the W3C Semantic Web recommendations, a lifecycle-spanning tool chain, and different levels of applicability. We label our method Semantic Business Web approach, since we build on W3C Semantic Web standards, use and extend them in the Business Web setting. Both artifacts are constructed in an interdisciplinary way by experts participating in the German lighthouse project THESEUS/TEXO. The project’s scenario also serves as a proof of concept evaluation of the artifacts.     

Optimized Software Licensing – Combining License Types in a License Portfolio

Although software licenses usually range among the most expensive items within the IT budget, they still lack the necessary attention by many companies. Therefore, most companies inadequately have implemented their software asset management neglecting further potential for cost reduction, which can be obtained by optimizing the use of different license types. This paper shows how possible savings can be realized by combining different types of licenses in a license portfolio. The model presented is based on the most common license types considering different user groups as well as their behavior. Additionally to cost risks, the risk of service quality is also taken into consideration. The following examples illustrate the model’s high relevance and show how it can be applied in practice. Accepted after two revisions by Prof. Dr. Hasenkamp.

与德里达关于消化力的局限的对话

90年代早期,在准备《如黄鼠狼吞蛋:一篇关于忧郁及同类相食的文章》一书时我们与晚年的德里达有过一些书信往来。那时他正研究在诠释学与德国唯心论中他所谓的同类相食的比喻。他很感激我们提供给他的一些诺瓦利斯残篇。     

Separating the Hawks from the Doves: Evidence from continuous time laboratory games

Human players in our laboratory experiment received flow payoffs over 120 seconds each period from a standard Hawk–Dove bimatrix game played in continuous time. Play converged closely to the symmetric mixed Nash equilibrium under a one-population matching protocol. When the same players were matched in a two-population protocol with the same bimatrix, they showed clear movement towards an asymmetric (and very inequitable) pure Nash equilibrium of the game. These findings support distinctive predictions of evolutionary game theory.     

Explaining the Cross‐Section of Stock Returns in Japan: Factors or Characteristics?

Japanese stock returns are even more closely related to their book-to-market ratios than are their U.S. counterparts, and thus provide a good setting for testing whether the return premia associated with these characteristics arise because the characteristics are proxies for covariance with priced factors. Our tests, which replicate the Daniel and Titman (1997) tests on a Japanese sample, reject the Fama and French (1993) three-factor model, but fail to reject the characteristic model.     

中国银行业是否从对外开放中获益

实证数据表明,由于外国投资者的进入,中国银行业的盈利能力和系统效率都得到了改善。在各种外资参与方式中,包括拥有中资银行的小额股权(这与新兴市场的典型做法并不相同),战略投资者的效果看起来最为卓著。纯粹的财务投资人对银行业绩的影响微乎其微。同时研究还发现,私人投资者比公共投资者更有影响力,无论公共投资者是国际组织还是主权财富基金。
