Through an analysis of survey data gathered from private firms in China, this study examines the impact of employee protection on corporate innovation ability. The results indicate that firms with more advanced employee protection have stronger innovation ability. Furthermore, the positive relationship between employee protection and corporate innovation ability is more pronounced in those enterprises with labor unions. Finally, a firm’s political connections strengthen the influence of employee protection on corporate innovation. These empirical findings highlight the positive consolidating effects of labor unions and political connections and will be of value to policy makers in emerging markets in gauging the important drivers of corporate innovation ability.  相似文献

The main aim of this study is to establish the effect of the Exploitation and Exploration; and the influence of these learning flows on the Innovative Outcome (IO). The Innovative Outcome refers to new products, services, processes (or improvements) that the organization has obtained as a result of an innovative process. For this purpose, a relationship model is defined, which is empirically contrasted, and can explains and predicts the cyclical dynamization of learning flows on innovative outcome in knowledge intensive firms. The quantitative test for this model use the data from entrepreneurial firms biotechnology sector. The statistical analysis applies a method based on variance using Partial Least Squares (PLS). Research results confirm the hypotheses, that is, they show a positive dynamic effect between the Exploration and the Innovative as outcomes. In the same vein, they results confirm the presence of the cyclic movement of innovative outcome with the Exploitation.  相似文献

Without guaranteed compensation, granted by the German Renewable Energy Sources Act (Erneuerbare Energien Gesetz/EEG), biogas plants compete with all other plant types on the market for electrical energy. However, exchange-based electricity products do not currently permit an economically viable operation of biogas plants owing to their cost situation.  相似文献

Making as a design-centered learning activity has recently received significant attention in education. We use literacies—how individuals use representations to learn—to explore the STEM literacy practices of experienced designers and makers. Describing makers’ representational practices in STEM contexts can inform the design of literacy supports for young makers that can encourage their use of representations to connect STEM disciplines and design practices. We interviewed experienced makers to describe one literacy practice central to design: identifying, organizing, and integrating information. Makers enacted this practice within specific making processes—e.g., designing—with the purpose of sourcing and navigating information related to their chosen problems. The research supports efforts to bridge learning while making with learning in schools by positioning STEM literacies as central practices involved in the processes of designing and making.  相似文献

Existing models of negotiation as a process are incomplete and do not show an overall, start to finish lifecycle. Current phase based models lack clearly defined criteria that identify phase boundaries. After reviewing existing models, the paper identifies macro phases, clarifies phase boundaries, and delivers a bird’s eye view model of negotiation supported by examples in academic literature and the public record. The enhanced model proposed here provides a practical negotiation guideline and roadmap previously left unclear in the literature. The proposed model contributes to theory around negotiation by defining the boundaries of a sequence of macro phases in negotiation and enhancing the model through business process modeling. With the enhanced model, academics and practitioners can share a viewpoint for understanding, communicating, and further developing negotiation models.  相似文献

Workplace bullying is a counterproductive behavior that has captured the attention of researchers in recent years. The extent of reported bullying behavior in US organizations varies however; it is estimated to affect 15% to 50% of workers with projected annual costs of over $40 billion including direct and indirect costs. Workplace bullying poses a serious ethical challenge by sending messages about appropriate conduct within the organization’s culture. In this study, we focus on environmental factors as predictors of self-reported bullying in a public-sector organization. Specifically, the factors of interest are organizational culture, commitment to change, and leader-member exchange (LMX). We also investigate newcomer status and its relationship to reported bullying. Findings demonstrated perceived stability in the organization and higher levels of LMX showed lower levels of workplace bullying. Further, an organizational culture that emphasizes rewards lead to higher levels of bullying and newcomers are subjected to more bullying than longer service workers.  相似文献

The paper shows that currencies of countries with persistent current account surpluses and high foreign-currency denominated assets, such as the Swiss franc and the Japanese yen, are under persistent appreciation pressure, particularly when the centres of the world monetary system follow expansionary monetary policies. This limits the choice of exchange rate regime. Given flexible exchange rates, a negative risk premium on the domestic interest rate can emerge. Empirical estimations provide mixed evidence for a negative impact of net foreign asset positions and exchange rate uncertainty on interest rates of international creditor countries at the periphery of the world monetary system.  相似文献
