Multidimensional configurations of the organizational climate construct

This study describes the creation and validation of a multidimensional model which assesses the level of employee satisfaction based on international theoretical models. It utilizes data collected from a sample of 518 public and private company employees during the year 2009 in the city/state of São Paulo, Brazil. In the first stage of the study, 15 independent dimensions were theoretically obtained. In the second stage, five different multiple dimensions were confirmed using structure equation modeling (SEM) technique, thus characterizing general configurations of the organizational climate construct denominated motivation, management philosophy, leadership, people management and nature of work. It is hoped that the model can contribute by enhancing managerial best practices of an organization by attending a major demand for those listed on stock markets, since these companies must periodically provide information on job satisfaction of their employees to maintain or achieve higher levels of corporate governance.     

Fostering product innovation in industry networks: the mediating role of knowledge integration

The locus of innovation has shifted from single entrepreneurial firms to groups of networked firms. Inter-organizational cooperation rather than competition to exploit the value of knowledge through new product innovation lies at the heart of the knowledge-based economy. This paper focuses on the phenomenon of network product innovation and the holistic integration of distributed knowledge across organizational boundaries to foster production innovation. A new construct, knowledge integration, is found to have a strong positive impact on new product performance. Resource complementarity, market orientation, and information sharing are three antecedents that positively affect knowledge integration across organizational boundaries. Survey data also suggest that knowledge integration serves as a mediator between the three antecedents and product innovation performance. Managerial implications and future research directions are discussed.     

Brazilian Micro-enterprises＇ An Exploratory Study on Marketing Strategies

This article aims to present the main marketing concepts applied by Brazilian micro-enterprises within a brief contextualization of a marketing plan. The methodology involved qualitative research development applied at the Trianon Fair, traditional event on Sundays on the sidewalks of the AvenidaPaulista in the city of Silo Paulo. Another research was carried out involving non-probabilistic sample with micro-businesses from various segments in the city that were chosen for their accessibility. From the results, product characteristics were elaborated, pricing, and distribution, that compose the application analyses of the marketing tools for micro-businesses and theoretical evolution have stemmed from the bibliographical research as well as field research and observational studies by the authors of the article. The goal is not to exhaust the topic nor to construct a Marketing Plan, but rather to contribute to the discussion, learning, and use of a marketing mix in the segment of micro-enterprises in a more assertive manner. It was concluded that there is no doubt as to the importance of micro-enterprises for any country. His contribution lies mainly in optical innovation and creativity because these companies can test new models of work, management, products, and services. It should be noted that micro-enterprises are greatly responsible for job generation in our country, denoting their prominent social and ecological perspective. More than a transient way of earning money, the reality of micro-enterprises should be considered as a social and economic phenomenon capable of generating regional and, consequently, global growth.     

Executive risk incentives,product market competition,and R&D

Prior studies have examined the relation between product market competition (PMC) and research and development (R&D) investments, while the impact of executive risk incentives on this relation remains unexplored. In this study, we find that Vega (the sensitivity of executives’ wealth to stock return volatility) weakens the negative relation between PMC and R&D. We also find that Vega strengthens the negative relation between PMC and firm performance when R&D investments grow higher. In sum, our results suggest that high‐Vega compensation portfolios in competitive environments may induce executives to overinvest in R&D projects, therefore hurting firm performance.     

The impact of stakeholder heterogeneity on risk perceptions in technological innovation

Managing risk has been widely acknowledged as a crucial managerial task in the development of new technology. More recently, the acceptance of new technologies has increasingly been influenced by secondary stakeholders, some of which are difficult to identify, or whose concerns are not easily reconciled. This paper develops a conceptual framework based on the management of technology and research & development literature, stakeholder theory, risk and social judgment to describe how traditional approaches based on reducing uncertainties through estimating probabilities may not work for social uncertainties; different heuristics are needed to understand and resolve such heterogeneous stakeholder perspectives. We contribute to the discourse by describing how risk perceptions among stakeholders vary, and how this may change over time. The framework suggests that the perception of primary stakeholder towards a specific innovation is ‘Standard’ when information is well known, but becomes riskier when information is unclear. For secondary stakeholders, when there is a low degree of imperfect information, the stakeholder relationship is an ‘Irritant’ but becomes increasingly ‘Dangerous’ when information becomes ambiguous. We conclude with implications for management and future research.     

Integrated Model of Marketing Quality (MARKET-Q) in the B-to-B Sector

In the past, product quality and relationships were the main concepts for a differentiation strategy in b-to-b markets. Currently, the brand is discussed as an additional concept in the b-to-b sector. In the past, the literature mostly analysed these marketing concepts in an isolated way. This paper presents for the b-to-b sector a new marketing quality model (MARKET-Q) which integrates product quality, relationship quality, and brand quality in a single framework. Furthermore, the results of empirical tests of this model are presented in this paper. A main study and two replications clarify the general procedure and the validity of the model. Additionally, the empirical studies underpin the high relevance of brands in the b-to-b sector.     

基于关系视角的农产品渠道模式选择研究

本文在国内外学者对渠道关系类型研究的基础上,依据一定的变量构建了基于农户——龙头企业——分销商的不同阶段的农产品渠道关系模型和渠道关系选择模式。在农户——龙头企业阶段,依据外部环境的不确定性、农户规模、龙头企业品牌知名度三个变量,渠道关系有四种可选择的模式;在龙头企业——分销商阶段,依据外部环境的不确定性、分销商对下游渠道创造增加值的能力和龙头企业品牌知名度三个变量,渠道关系也有四种可供选择模式,但这些不同的渠道关系模式承诺水平表现出一定的差异。     

生命周期结束产品再生模式选择分析

本文认为,对生命周期结束的产品进行再造、翻新、再生是逆向物流的主要内容,也是企业管理的重要组成部分,对供应链具有重要意义。文章提出,影响再生模式选择的因素主要有两个:一是生命周期结束的产品是否适合拆解;二是再生处理的执行是否外包。这两个因素密切相关,决定着再生的四种可供选择的模式,即再生不拆解外包(低成本选择)、再生并拆解外包(折中的再生方式)、企业再生不拆解(控制物料和创建新的市场)、企业再生并拆解(通过循环供应链创造独特的价值),这四种模式都是可行的选择。外包必须在合乎环境要求的情况下进行,外包具有前期成本相对较低的优势,但也有风险。企业独自或积极参与再生,是企业发展的新思路。企业独自或积极参与再生并拆解,从竞争角度看是一种高风险的选择,要求企业固定资产投资较高并能引发企业发展战略的重大转移,这种选择一旦成功,企业将获得丰厚回报,减少或消除对原材料和市场的依赖性,减少环境风险,保证用户最终得到既经济又环保的新颖产品。     

新古典经济学生产理论的合理性与缺陷分析

新古典经济学生产理论对经济分析史具有重要贡献,但也有内在缺陷。其贡献在于其改造并建立了劳动理论;强调生产理论的主观性具有强烈的现代意义;提供了一个分析厂商行为的理论模型。其缺陷在于忽视了生产者的主观创造性;不适应垄断市场条件;排除了不确定性因素;只从交换角度研究生产。
