We examine the extent to which both in-role (task performance) and extra-role dimensions of performance (organizational citizenship behaviors) account for variance in ratings of overall job performance by utilizing currently available meta-analytic estimates. Relative weight analysis results show that overall performance is determined more by three OCB forms in combination (RW = 0.34; %RW = 72.9%) than by task performance (RW = 0.12; %RW = 27.1%). Among the OCB forms, the relative weight of OCB-O (RW = 0.17; %RW = 36.9%) is greater than those of OCB-I (RW = 0.11; %RW = 0.22.9%) and OCB-CH (RW = 0.06; %RW = 13.1%). Consistent with the results from a relative weight analysis, results from a series of multiple regression analyses also show that the incremental contribution (ΔR2) of each performance dimension above and beyond the other performance dimensions is the highest for OCB-O (0.056), followed by those of task performance (0.041), OCB-CH (0.007), and OCB-I (0.003). We discuss the theoretical and practical implications of these findings along with study limitations and future research directions.  相似文献

This paper reports the results of a meta-analytic review of the relationship between person and task-focused leader behaviors, on the one hand, and team performance, on the other hand. The results, based on 89 independent samples, show a moderate positive (ρ = 0.33) association between both types of leadership behaviors and subjective team performance. For objective team performance, the effect sizes are smaller, yet positive (ρ = 0.19 for task-focused leadership behaviors and ρ = 0.18 for person-focused leadership behaviors). Furthermore, with respect to the methodological moderators, the analyses show that the relationships were stronger when leadership behaviors were rated by the leaders themselves, rather than by others, and the association was stronger when the correlations were estimated at the individual level, as opposed to the team level of analysis. Concerning conceptual moderators, team type was identified as a significant moderator, and correlations between a person-focused leadership behavior and team performance were stronger for service and project teams than for action/performing teams. Task interdependence was another moderator tested in our meta-analysis, yet our results show no clear moderating effect of task interdependence on the relationship between leadership behavior and team performance.  相似文献

We analyze a two-period signaling model in which a representative entrepreneur in a regional economy has a project that generates a random cash flow and that requires investment that the entrepreneur raises from a competitive market. The project's type is known to the entrepreneur but not to the investors. Further, the entrepreneur is restricted to issuing debt only or equity only. We first show that there is no separating perfect Bayesian equilibrium (PBE) contract involving the issuance of equity only, that there exists a pooling PBE contract involving the issuance of equity only, and that a debt contract is preferred to an equity contract by our entrepreneur. Next, we suppose that the entrepreneur incurs a non-pecuniary cost of financial distress F > 0 whenever he is unable to make a repayment at time t = 1. We provide conditions on F under which a pooling PBE contract with debt exists and a separating PBE contract with debt and equity exists. Finally, we examine whether a high type entrepreneur will prefer a setting with a cost of financial distress (F > 0) or a setting in which there is no such cost (F = 0).  相似文献

At present, several initiatives have emerged that claim to be innovative while acting according to the mechanisms of open source software (OSS), a field frequently deemed to be a role model for open innovation. Against this background, this study focuses on a case study of the development of an automobile. Based on a commons-based peer production-informed perspective, we show that this project displays a variety of characteristics that are usually associated with OSS projects. In particular, parallels can be drawn between the intrinsic and extrinsic motivations, the ability to ‘broadcast’ ideas due to the virtual nature of the tasks, and the self-selection of tasks due to their modular nature. The drawing of such parallels, however, must be done cautiously because diverse factors, such as opportunity costs, regulations, and feasibility studies, limit the applicability of OSS principles to this non-software related network of dispersed voluntary contributors within a commons-based peer production framework. Herein, we attempt to clarify how OSS projects can and cannot work as role models for open innovation in the automotive as well as other product-oriented industries.  相似文献

This paper considers a dynamic model of the evolution of open‐source software projects, focusing on the evolution of quality, contributing programmers, and users who contribute customer support to other users. Programmers who have used open‐source software (OSS) are motivated by reciprocal altruism to publish their own improvements. The evolution of the open‐source project depends on the form of the altruistic benefits: in a base case the project grows to a steady‐state size from any initial condition; whereas adding a need for customer support makes zero‐quality a locally absorbing state. We also analyze competition by commercial firms with OSS projects. Optimal pricing policies again vary: in some cases the commercial firm will set low prices when the open‐source project is small; in other cases it mostly waits until the open‐source project has matured.  相似文献

This study examines how government funding type affects the financialization of manufacturing enterprises in China and discusses the different impacts of environmental factors. Funding for production can induce managers to increase expenses and reduce main business income by assigning social objectives, promoting corporate financialization. However, state-owned enterprises (SOEs) may suffer from soft budget constraints and ignore short-term revenue; enterprises in competitive industries tend to hold cash for precautionary motivation. Therefore, their financialization is insensitive to government funding. In addition, funding for interest can inhibit corporate financialization by increasing debts for non-SOEs and those with financial background employees or facing strong financing constraints, because they are lacking in capital or sensitive to financial risks.  相似文献

Realizing the innovation potential of OSS communities, firms now create or sponsor their own open source software (OSS) communities, generally as part of an open innovation strategy. However, maximizing the innovation capability of a sponsored OSS community is a challenging task since firms cannot rely on traditional hierarchical authority to control community members. Furthermore, a firm's efforts to manage its sponsored community may also impact the firm's absorptive capacity, or its ability to effectively absorb and leverage the valuable knowledge created by the community. Thus, the purpose of this article is to investigate two research questions: 1) How does the boundary management of a firm-sponsored OSS community impact the community's innovation capacity? and 2) How does the boundary management of a firm-sponsored OSS community impact the firm's absorptive capacity? Using the results from our qualitative analysis of eZ Systems and its successfully sponsored OSS community – eZ Publish – we develop a theoretical model depicting how the boundary management of a firm-sponsored OSS community influences both the community's innovation capacity and the absorptive capacity of the firm. In addition, the results of our study highlight the central importance of an integrative IT platform in boundary management activities.  相似文献

As organizations recognize the importance of open innovation, understanding emerging mechanisms for soliciting outside participation is a growing area of academic interest. Strategies can be as diverse as hosting innovation contests, sponsoring open source software (OSS) communities, or engaging in bilateral partnerships. While these have been studied as distinct strategies, more recent work has identified the possibility for combining these approaches, or deploying different methods at different times. Because each of these open innovation strategies are characterized by different incentive systems as well as different work and social practices, the combination of these can reveal unexpected participant responses (e.g., collaboration in innovation contests, competitive behavior in OSS communities). This study examines an explicit attempt to combine these strategies, to host an open source innovation contest. Through the case of Google's Android Developer Challenge, a series of multi-million dollar innovation contests used to launch an OSS community over several years, this study utilized a process approach to understanding open source innovation contests to understand how participants responded and also how the contest conditions changed over time. We found several practices of competition and collaboration that worked around the short term and long term incentives and constraints posed by the contest. We also followed the contest through various transition phases and found that participants reacted strongly to changes in structure, execution, and shifting conditions over time. Through this case, we extend our understanding of innovation contests as a process and specifically the promises and pitfalls of open source innovation contests.  相似文献

Considering that current structures are the result of choices made in specific contexts in the past, we adopt a historical perspective in order to understand how some information systems (IS) project management practices evolved and became norms. Using historical methods, we analyze sources of data spanning 52 years of IS project management (1945–2007) – interviews with IS project managers and academics, IS project management textbooks, curricula, and the scientific and professional literature – to: (1) determine whether some IS project management practices may now be considered institutionalized, and (2) understand their institutionalization processes over time. Based on this analysis, three groups of IS project management practices may now be considered institutionalized: formal control, external integration, and project risk management.  相似文献

Managers both competent and willing to share resources can be critical to the performance of the multi-project settings increasingly common to modern organizations. Drawing on theoretical perspectives from the psychological ownership literature, we examine the impact of project manager (PM) task self-efficacy and perceptions of project work-planning difficulty on resource sharing behaviors. In this study we use a laboratory experiment involving practicing PMs to elicit work assignments for their subordinate team-members across a series of predefined projects. We control for the difficulty of these assignment tasks and follow-up by inquiring into the willingness of the PMs to share human resources that they’ve assigned to work in these projects. The results from the experiment involving 161 professional PMs suggest that difficulty in project work-planning in general has a significant impact on sharing behaviors. Consistent with the implications of psychological ownership theory, this relationship is significantly moderated by project managers’ task self-efficacy. Theoretical and practical implications of these results are discussed.  相似文献

Current research continues to establish the importance of communication in the management of projects. However, little is known about the behavioral aspects of project managers' communication competency especially as they relate to crucial outcomes in virtual environments. This article reports on a survey‐based research study of 564 respondents from the Chief Project Officer Web site that validates and extends a research model of project managers' competencies in decoding and encoding communication, the satisfaction and productivity of their team members, and the degree of virtuality present in the project. The findings indicate that project managers' competencies in decoding and encoding communication significantly contribute to team member satisfaction and productivity. In addition, geographic dispersion plays an unexpected and significant role in how project managers' competency in decoding and encoding communication impacts team member satisfaction and productivity.  相似文献

While research on user innovations within communities exists mainly in offline contexts, few studies have attempted to define the profile of lead users in online (or virtual) communities, and even fewer have been conducted in the specific context of online brand communities, formed by people with a “common interest in a brand,” in its evolution and in the discourse about it. This study focuses on innovative activities within the Ducati Motor online community. The research reveals the following characteristics as crucial factors for the identification of lead users in online brand communities: willingness to collaborate, product knowledge and strategic alignment with the brand identity. Our sample consists of 2071 messages posted by 572 Ducati Motor virtual community members in a specific blog developed by Ducati Motor with the purpose of involving members in a collaborative innovation process that took nearly 14 months. Several implications for scholars and new product development managers are discussed.  相似文献

Learning is one of the main goals of any training program. Much research has focused on how learning may be enhanced through effective training design. We compiled the extant literature exploring the efficacy of five common pre-training interventions in promoting learning. Meta-analytic results (k = 159; total N = 13,684) reveal consistent positive effects for the role of such interventions in learning. Attentional advice and goal orientation (as compared with meta-cognitive strategies, advance organizers and preparatory information) yielded the most consistent learning gains. Results suggest intervention format, implementation, and match to learning outcome are important considerations. Recommendations are provided for interventions which are useful in promoting cognitive, skill-based, and affective learning gains.  相似文献

This article investigates the soft competencies by project phase that information systems (IS) project managers require for project success. The authors conducted 33 qualitative interviews to collect data from a sample of 22 IS project managers and business leaders located in Calgary, Alberta, Canada. The authors identified the key competencies for each of the IS project phases (initiation, planning, implementation, and closeout). The competencies were sorted into competency categories: personal attributes (e.g., eye for details), communication (e.g., effective questioning), leadership (e.g., create an effective project environment), negotiations (e.g., consensus building), professionalism (e.g., lifelong learning), social skills (e.g., charisma), and project management competencies (e.g., manage expectations). Each of the most important competencies is discussed and interconnections among competencies identified. How this research can be used by the practitioner and academic communities and the broader implications of this research are examined.  相似文献

This paper investigates how China's stock market reforms have affected the stock market linkages between China and Korea, Japan and the US respectively. We firstly use a 4 × 4 asymmetric GARCH-BEKK model and a series of likelihood ratio tests to uncover China's regional and global linkages between 1992 and 2010 and during three sub-periods representing the stages of the Chinese reforms. The results show that Chinese stock market is linked to these overseas markets and the reforms permit spillovers to these markets from China. The subsequent regression analyses of the time-varying conditional correlations, in the presence of growing economic integration, exchange rate risk and financial turbulence, further indicate that the interdependences between China and the regional markets increase due to the implementation of liberalisation policies. However, the correlation between China and the global market remains weak even though this correlation responds positively to the institutional reforms on China's stock market additionally.  相似文献

This paper examines the effect of the introduction of permanent benefit reductions for early retirees (i) on the duration until benefit claiming and (ii) on the duration until exit from gainful employment. I estimate discrete time duration models using different error term specifications. Administrative data containing the full earnings history of the individuals are used. Since the reform implementing the benefit reductions was a natural experiment, under some assumptions a causal effect can be identified. The permanent reduction of retirement benefit amounts causes a postponement of claiming benefits by about 14 months and a delay of employment exit by about 10 months on average.  相似文献

While Open Source Software (OSS) communities provide opportunities for knowledge creation, we have a limited understanding of how entrepreneurs leverage OSS communities for their entrepreneurial ventures. Using social capital theory in a mixed methods case study, we compare entrepreneur and non-entrepreneur behaviors to investigate how entrepreneurs build social capital within an OSS community. This study shows that entrepreneurs differentiate themselves from non-entrepreneurs by focusing on cognitive and relational capital building activities, which in return makes it possible for them to leverage their social capital to influence and shape the environment in which they are operating. Our findings suggest that entrepreneurs strategically select which activities within the community to expend their limited resources on (e.g., developing code over participating in email conversations) and build their social capital more through their actions than through their words (e.g., showing their commitment to the community through code commits, bug fixes, and documentation). Given the liabilities of newness and smallness as well as other challenges faced by entrepreneurs, applying an open innovation strategy in OSS communities could be one approach where entrepreneurs, by developing and freely revealing their intellectual property to the community, share their way to success via OSS-infused entrepreneurial business ventures.  相似文献

This article addresses some aspects of project management theory on a basis of an in-depth longitudinal case study of the Lillehammer Olympics Organizing Committee (LOOC) before and during the XVII Olympic Winter Games in 1994. Particular emphasis is put on the implications of two characteristics of this project: the fact that it was not embedded in any parent organization, and that its task was imbued with uncertainty. As a result, emergent tasks, emergent structure and informal authority appear to have been critical features. Because of the non-embedded nature of the Olympic Winter Games project the case has also illustrated the value of viewing projects like this one as temporary organizations rather than as projects initiated by a parent organization.  相似文献

Efficient project execution is a key business objective in many domains and particularly so for capital projects in the process industries, but existing project management research gives little direction about how project team factors influence three important capital project outcomes: cost, schedule, and operability. After an extensive cross-disciplinary review of the general team and project management literatures, we constructed and tested a theoretically based, five-dimensional model of organizational context, project team design, project team leadership, project team processes, and project outcome factors. We examined the model by means of an empirical study of 56 newly completed capital projects executed by 15 Fortune 500 companies in the process industries. The results indicate the value of disaggregating project outcomes for research purposes. Different bundles of project team factors were found to drive project cost, schedule, and operability. Project team efficacy, cross-functional project teams, autonomous project team structure, and virtual office usage were the strongest predictors of project cost effectiveness. Continuity of project leadership, cross-functional project teams, and project manager incentives were the strongest predictors of project construction schedule. In contrast, clear project goals and an office design to facilitate effective communication were the main predictors of plant operability. Implications of these findings for researchers and project practitioners are discussed. One major practical implication of our findings is that project managers need to clearly focus and prioritize their goals for each project so they can adopt the appropriate bundles of project team practices that will facilitate their goal achievement.  相似文献
