The individuals' discretionary behaviors at work. An overview and analysis of its growing interest
Nearly forty years have passed since the term Organizational Citizenship Behavior appeared. Despite a current consensus among scholars about the citizenship gestures as prosocial acts of employees that benefit the organization, it does not apply commonly to the exponential growth of all OCB-related concepts. The concept's expansion has confused the researchers and practitioners, mainly when choosing the most appropriate instruments (constructs) and dimensions to use in their area of interest and context. A systematic literature review was conducted and 420 articles were analyzed. Results point that the trends on OCB-like behaviors goes higher, with an average annual growth rate of new studies of 3.13%. United States (39%) and China (25%) lead but some "under-studied" contexts like Africa, Latin America, the Caribbean, and Oceania start being studied towards OCB. New trends appear in the spectrum of the many different domains and disciplines related to OCB, while leadership and task performance remain the most studied domains and disciplines. In future studies, researchers must freely choose the OCB dimensions and constructs they want to use or adapt to meet their needs and research needs since there is no written rule about their use, only the care to be taken with the context and discipline studying.info:eu-repo/semantics/publishedVersio
Research and Consultancy Services in the Mining Industry in Zimbabwe: A Coordinated Approach Through the Mineral Resources Centre
IMR Report.Education in the engineering fields can be considerably enhanced if it is designed to address the immediate and long-term needs of society. In this context education not only comprises the provision of basic training, but also includes the careful planning and execution of applied and fundamental research. This paper focuses on education and research institutions that provide services to the mining sector in Zimbabwe and describes a new approach to meeting high-quality teaching, research and consultancy requirements against a background of diminishing government funding.
Key units within the University of Zimbabwe providing services to the mining industry include the Institute of Mining Research, The Departments of Geology and Physics in the Faculty of Science and Mining Engineering and Metallurgy in the Faculty of Engineering. Within government, services are provided principally by the Departments of Geological Survey, Metallurgy and Mining Engineering, and the Scientific and Industrial Research and Development Centre. The major source of funding for all of these institutions is Government.
There is a degree of overlap between these institutions, some of which were established more than 30 years ago with terms of reference appropriate for the time. With decreasing funding exacerbated by a harsh economic climate in Zimbabwe there is need to revisit the charters of these organizations and to review the provision of services to the mining sector.
Recognition of this situation has led the Department of Geology to spearhead a new initiative to establish an alternative structure through which consultancy and research in mining related topics can be coordinated at the University of Zimbabwe. The Mineral Resources Centre (MRC) was established to facilitate fund-raising activities through consultancy services, research, postgraduate training and capital investment. By representing a group of like-minded stakeholders, the MRC can address larger projects, and thus secure more funding than individual entities will be able to obtain. The MRC is designed to be a lightweight structure that will not replace any of the existing teaching and research departments.
The MRC is not be bound to any particular faculty within the university, and may even include stakeholders from outside the university. Interested parties are invited to participate on a voluntary basis in accordance with the management and quality- control guidelines laid out by the MRC. Participation is on a contract basis and will be determined for each project.
Service providers that participate in the MRC agree to use their resources in the best possible way, so that services can be presented in unison. In combining forces between various departments with expertise in Earth Sciences, it is envisaged that a wider audience can be reached, a better service can be provided and a larger resource base can be tapped both within the private and the public sectors. The MRC may help coordinate capital investment, and human resource development in the various participating entities. Considering the limited availability of financial and human resources in Zimbabwe, coordination and prevention of unnecessary overlap is in itself a valuable exercise
Possible unconventional superconductivity in substituted BaFeAs revealed by magnetic pair-breaking studies
The possible existence of a sign-changing gap symmetry in
BaFeAs-derived superconductors (SC) has been an exciting topic of
research in the last few years. To further investigate this subject we combine
Electron Spin Resonance (ESR) and pressure-dependent transport measurements to
investigate magnetic pair-breaking effects on BaFeAs (
Mn, Co, Cu, and Ni) single crystals. An ESR signal, indicative of the presence
of localized magnetic moments, is observed only for Cu and Mn compounds,
which display very low SC transition temperature () and no SC,
respectively. From the ESR analysis assuming the absence of bottleneck effects,
the microscopic parameters are extracted to show that this reduction of
cannot be accounted by the Abrikosov-Gorkov pair-breaking expression for a
sign-preserving gap function. Our results reveal an unconventional spin- and
pressure-dependent pair-breaking effect and impose strong constraints on the
pairing symmetry of these materials
Optical and Near Infrared Study of the Cepheus E outflow, a very low excitation object
We present images and spectra of the Cepheus E (Cep E) region at both optical
and infrared wavelengths. Only the brightest region of the southern lobe of the
Cep E outflow reveals optical emission, suggesting that the extinction close to
the outflow source plays an important r\^ole in the observed difference between
the optical and IR morphologies. Cep E is a unique object since it provides a
link between the spectroscopic properties of the optical Herbig-Haro (HH)
objects and those of deeply embedded outflows.Comment: Accepted Astron. J., 8 files: paper, tables plus 6 figure
