The paper analyses how multinational enterprises (MNEs) manage their interactions with host governments during the market entry process. A qualitative multiple case study collected data through in-depth interviews with multiple participants in six New Zealand MNEs. The analysis identifies two distinct political schemas which represent MNE managers’ assumptions and heuristics regarding how to approach interactions with foreign governments, systematic and episodic, which lead to the enactment of distinct patterns of political activities, each supported by certain political resources and capabilities. We then identify several sources of the variations in these two political schemas at the managerial, firm, industry, and country levels of analysis. Our study deepens understanding of the micro-processes of corporate political activity (CPA) and the processes and activities through which political resources and capabilities are developed, deployed and leveraged by MNE actors in managing their interactions with host governments during the market entry process. In doing so, we highlight the role of international experience in influencing the process of political capability development, and also the role of managerial actions in shaping this evolutionary process. 相似文献

To assess the dose of UV light needed to achieve specified levels of Giardia spp. cysts and Cryptosporidium spp. oocysts inactivation in drinking water, a Bayesian meta-analysis is used to analyze experimental data from several studies. Of the 20 studies identified by an extensive data collection effort, 14 (five reported experiments on Giardia and nine on Cryptosporidium) were selected for analysis based on a set of criteria. A substantial amount of the log inactivation data are reported as greater than a given inactivation level (i.e., censored data). The Bayesian hierarchical modeling approach used in this study not only properly addresses the common concerns in a meta-analysis but also provides a robust method for incorporating censored data. Different statistical models will result in different estimates of the UV doses needed to achieve a specific inactivation level. The Bayesian approach allows us to present the uncertainty in terms of risk, which is better suited for supporting US EPA in developing regulations. 相似文献

Collective action and community ecology theories frame this study of longitudinal interorganizational networks in Croatia during the country's political transition. As time progresses toward political stability, grass-roots organizing activities shift through participation in new networks. Although engaged cross-sector communication was important in early stages of the transformation, homophilous partnering emerged as the system stabilized. System stability left room for organizations to exit the collective action network but with costs associated with centralized organizing. Over time, organizations embodied roles as ideological leaders, collective action network leaders, and within-sector network partners. We offer a unique contribution to community ecology and collective action theories with a communication-centered framework that emphasizes the nature of communication in interorganizational networks over a 4-year period. 相似文献

Novel insights on the impact of top water on Steam‐Assisted Gravity Drainage in a point bar reservoir 下载免费PDF全文
As efforts are made to efficiently exploit and recover bitumen resources in Canada, increasingly more complex reservoirs in the Athabasca area continue to challenge the application of Steam‐Assisted Gravity Drainage (SAGD) technology. Several studies have been done to investigate the impact of heterogeneities/complexities such as shale barriers, lean zones, and top and bottom water on the performance of the SAGD process. However, the literature is deficient for point bar deposits with top water zones, a common occurrence in oil sands systems. This study, by using thermal reservoir simulation, examines SAGD performance in a point bar deposit reservoir where an overlying top water and an inclined heterolithic strata (IHS) is present. The results show that where the top water is unconfined and steam injection pressure is higher than that of the top water zone, there is a loss of thermal energy, but the top water does not impact steam chamber development. At steam injection pressure lower than that of the top water zone, top water continuously drains into the reservoir and constrains the size of the chamber. However, the IHS zone helps to delay drainage of the top water into the chamber when steam is injected at underbalanced conditions. Finally, under proper steam injection pressure conditions, top water production can be considerably delayed. 相似文献

This paper builds upon the literature which provides conflicting theoretical insights and empirical results concerning the importance of companies’ collaborative relations, their position within a network of collaborative relations and the effects on their innovative performance. Taking the importance of collaborations and networks in the pharmaceutical industry into account, the paper untangles the influence of the firm’s co-publication relations with different types of partners and its network position on the company’s product innovation in a specific disease area—cancer. We find rather robust evidence that in particular, companies’ indirect connections within the co-publication network, including connections to academic institutions and biotechnology companies, support product innovation. In contrast to evidence in the strategic alliance literature, direct co-publication links to biotechnology companies do not support product innovation in terms of new cancer medications. 相似文献

The growth in popularity of smart environments has been quite steep in the last decade and so has the demand for smart health assistance systems. A smart home-based prompting system can enhance these technologies to deliver in-home interventions to users for timely reminders or brief instructions describing the way a task should be carried out for successful completion. This technology is in high demand given the desire of people who have physical or cognitive limitations to live independently in their homes. In this paper, with the introduction of the “PUCK” prompting system, we take an approach to automate prompting-based interventions without any predefined rule sets or user feedback. Unlike other approaches, we use simple off-the-shelf sensors and learn the timing for prompts based on real data that are collected with volunteer participants in our smart home test bed. The data mining approaches taken to solve this problem come with the challenge of an imbalanced class distribution that occurs naturally in the data. We propose a variant of an existing sampling technique, SMOTE, to deal with the class imbalance problem. To validate the approach, a comparative analysis with cost-sensitive learning is performed. 相似文献

Currently, energy performance indicators for buildings are associated with the primary energy source consumption, CO2 emissions or net energy distribution, which together set the building’s energy efficiency. The evaluation is frequently based on setpoint temperatures and hours of operation. However, these fixed parameters are not suitable for social housing simulation as their performance tends to be in free running, excluding extremely cold or warm conditions. Therefore, a more successful assessment for the efficiency of these buildings is the users’ capability to live within adaptive comfort ranges without air conditioning systems. The aim of this research is to analyze new Chilean standards for sustainable social housing in the context of climate change using the adaptive comfort approach addressed in EN 15251:2007. Using EnergyPlus simulation software, 16 parametric series are analyzed for current conditions and validated against on-site measurements. Meanwhile, a prediction for the climate in 2050 has also been taken into account. The case study is the most widespread low cost dwelling model. The study demonstrates that the period of time within thermal comfort conditions varies substantially if analysis is done using the adaptive comfort standard or the Sustainable Construction Code (CCS) for Chilean housing. Considering climate change, the percentage of time fluctuates from ?19.00% to 24.30%. Concluding that the adaptive comfort model has a greater capacity to positively assess indoor temperatures for social housing in Central-Southern Chile. This research also establishes that it is possible to provide homes where standards are improved within comfort conditions without using artificial means, 99.67% of the time currently and 88.89% in the future. 相似文献

The discrete modelling and understanding of the particle dynamics in fluidized bed apparatuses, mixers, mills and others are
based on the knowledge about the physical properties of particles and their mechanical behaviour during slow, fast and repeated
stressing. In this paper model parameters (modulus of elasticity, stiffness, yield pressure, restitution coefficient and strength)
of spherical granules (γ-Al2O3, zeolites 4A and 13X, sodium benzoate) with different mechanical behaviour have been measured by single particle compression
and impact tests. Starting with the elastic compression behaviour of granules as described by Hertz theory, a new contact
model was developed to describe the force-displacement behaviour of elastic-plastic granules. The aim of this work is to understand
the energy absorption during compression (slow stressing velocity of 0.02 mm/s) and impact (the impact velocity of 0.5–4.5 m/s)
of granules. For all examined granules the estimated energy absorption during the impact is found to be far lower than that
during compression. Moreover, the measured restitution coefficient is independent of the impact velocity in the examined range
and independent of the load intensity by compression (i.e. maximum compressive load). In the case of repeated loading with
a constant load amplitude, the granules show cyclic hardening with increasing restitution coefficient up to a certain saturation
in the plastic deformation. A model was proposed to describe the increase of the contact stiffness with the number of cycles.
When the load amplitude is subsequently increased, further plastic deformation takes place and the restitution coefficient
strongly decreases. 相似文献

Reviews the book, Sexualized violence against women and children: A psychology and law perspective by B. J. Cling (see record 2004-21899-000). This book uniquely combines the fields of law and psychology in addressing the topic of sexual victimization of women and children. Clearly, violence of this nature continues to require attention in the literature, and this book provides an excellent historical and current understanding of the multifaceted issues involved in these crimes. The book consists of three parts: sexualized violence against women, sexualized violence against children, and perpetrators of sexualized violence and other harms against women and children. This is an excellent sourcebook for those who work in the area of sexual victimization, as it blends the worlds of law and psychology. It provides a thorough understanding of the interplay of victims, offenders, and the legal system. Strengths of the book include the breadth of information, as well as the citation of current literature and legal precedents. The editor has clearly chosen authors who are expert in their scholarship, allowing both the experienced clinician and the emerging professional to benefit from reading this book.
