Erfassung betriebswirtschaftlich relevanter Zeitschriften in den ISI-Datenbanken sowie der Scopus-Datenbank 总被引:1,自引:1,他引:0
Zusammenfassung Publikations- und Zitationsindizes k?nnen insbesondere zur Quellenerschlie?ung und Forschungsevaluation genutzt werden. Die
Eignung entsprechender Indizes zur ad?quaten Erfüllung dieser Funktionen h?ngt ma?geblich von der Auswahl der indexierten
Publikationen ab. In diesem Beitrag wird die Publikationsauswahl des Social Sciences Citation Index (SSCI), des Science Citation
Index-Expanded (SCI-X) und der Datenbank Scopus aus Sicht der deutschsprachigen Betriebswirtschaftslehre analysiert. Als Basis
für die Untersuchung dienen die Ergebnisse des VHB-JOURQUAL. Neben einem Gesamtüberblick zur Erfassung betriebswirtschaftlich
relevanter Zeitschriften in den Datenbanken wird auch die Abdeckung einzelner betriebswirtschaftlicher Forschungsfelder untersucht.
Da die Nutzung der Indizes mit einigen Kosten für den Erwerb entsprechender Lizenzen verbunden ist, erfolgt darüber hinaus
eine vergleichende Analyse von SSCI, SCI-X und Scopus hinsichtlich der Zeitschriftenabdeckung. Aufgrund der internationalen
Ausrichtung der betrachteten Zitationsindizes wird die Untersuchung zus?tzlich auf ein internationales Zeitschriftenranking
ausgedehnt.
Acquisition of economic journals in the ISI-databases and in Scopus
Summary Publication- and citation-indices are especially used for searching literature and evaluating research performance. Their suitability strongly depends on the publications taken into account. In this paper we analyse the selection of publications in Social Sciences Citation Index (SSCI), Science Citation Index-Expanded (SCI-X) and Scopus for G erman speaking researchers of business economics. Therewith, the VHB-JOURQUAL provides a basis for our analysis. In addition to an overview of economic relevant journals in the indices we analyse the coverage of special fields of business economics. Due to the fact that using such indices is very expensive, we compare SSCI, SCI-X and Scopus concerning their coverage of journals. As the indices are of international orientation, we enlarge the analysis onto an international ranking of publications.

Schmitz CL, Matyók T, James C, Sloan LM. The relationship between social work and environmental sustainability: Implications for interdisciplinary practice The Brundtland Commission, formally the World Commission on Environment and Development, established by the United Nations in 1983, links peace, security, development and the environment claiming that war, poverty and structural violence result in the oppression and degradation of the human community as well as the physical environment. Likewise, human rights and social and environmental justice are intertwined, and social work, as a profession that collaborates across disciplines and within communities, is uniquely situated to provide leadership in the field of environmental studies. Its strong focus on human rights, social justice and community building creates a sound base from which to engage in the collaborative, creative, interactional processes required for environmental practice. This article seeks to discern a model for environmental social work within the context of interdisciplinary practice with peace and conflict workers and through the integration of inclusive models of economic development. 相似文献

Summary: Commonly used standard statistical procedures for means and variances (such
as the t–test for means or the F–test for variances and related confidence procedures) require
observations from independent and identically normally distributed variables. These
procedures are often routinely applied to financial data, such as asset or currency returns,
which do not share these properties. Instead, they are nonnormal and show conditional
heteroskedasticity, hence they are dependent. We investigate the effect of conditional
heteroskedasticity (as modelled by GARCH(1,1)) on the level of these tests and the coverage
probability of the related confidence procedures. It can be seen that conditional
heteroskedasticity has no effect on procedures for means (at least in large samples). There
is, however, a strong effect of conditional heteroskedasticity on procedures for variances.
These procedures should therefore not be used if conditional heteroskedasticity is prevalent
in the data.*We are grateful to the referees for their useful and constructive comments. 相似文献

Who intends to leave Africa and what drives people to emigrate? For the cases of Ghana, Senegal, Morocco and Egypt, we examined peoples' stated intentions to emigrate. The large majority wants to move “out of Africa”, and the typical potential migrant was found to be young, male, displaying relatively modern values and optimistic about the net benefits of emigration. Signs of positive self-selection were clearly evident in Ghana and Egypt, particularly among women. However, negative self-selection was apparent among Moroccan men. The network effects of potential migrants were found to be fairly important in Ghana and Egypt, but in Senegal and Morocco, such ties play no role in triggering emigration intentions. 相似文献

Freese and Powell make a number of critiques of the theoretical assumptions, statistical methods, and use of variables in our paper, which raises questions about the typical use of the equal environments assumption in twin research. We do not find that any of their critiques modify our conclusion that the equal environments assumption cannot be taken for granted but must be subjected to empirical testing. We hope that our paper and the resulting exchange will lead sociologists to become more actively involved in the debate regarding the extent of genetic and environmental influences on social behaviors. 相似文献

Are remittances determined by altruism or enlightened self-interest, and do they trigger additional migration? In this paper these two questions are examined empirically in relation to data from Egypt, Turkey, and Morocco for households with family members living abroad. It is shown, firstly, that one cannot argue exclusively either for altruism or self-interest as motives, since for each country the data tell a different story and both motives can be identified as driving forces behind remittance behaviour. The general conclusion of this study is that the family ties and the net earnings potential of migrants have stronger effects on the flow of remittances than the net earnings potential of the households in the country of origin. Secondly, because the receipt of remittances has a positive effect on the emigration intentions of household members still living in the country of origin, the receipt of remittances may contribute to new flows of migration, particularly in the case of Morocco. 相似文献

In this paper, we show a simple correction for the aggregation effect when testing the relationship between income inequality and life expectancy using aggregated data. While there is evidence for a negative correlation between income inequality and a population’s average life expectancy, it is not clear whether this is due to an aggregation effect based on a non-linear relationship between income and life expectancy or to income inequality being a health hazard in itself. The proposed correction method is general and independent of measures of income inequality, functional form assumptions of the health production function, and assumptions on the income distribution. We apply it to data from the Human Development Report and find that the relationship between income inequality and life expectancy can be explained entirely by the aggregation effect. Hence, there is no evidence that income inequality itself is a health hazard. 相似文献
