Through an objective, systematic, and comprehensive review of the literature on open innovation (OI), this article identifies gaps in existing research, and provides recommendations on how hitherto unused or underused organizational, management, and marketing theories can be applied to advance the field. This study adopts a novel approach by combining two complementary bibliometric methods of co‐citation analysis and text mining of 321 journal articles on OI that enables a robust empirical analysis of the intellectual streams and key concepts underpinning OI. Results reveal that researchers do not sufficiently draw on theoretical perspectives external to the field to examine multiple facets of OI. Research also seems confined to innovation‐specific journals with its focus restricted to a select few OI issues, thereby exerting limited influence on the wider business community. This study reveals three distinct areas within OI research: (1) firm‐centric aspects of OI, (2) management of OI networks, and (3) role of users and communities in OI. Thus far, studies have predominantly investigated the firm‐centric aspects of OI, with a particular focus on the role of knowledge, technology, and R&D from the innovating firm's perspective, while the other two areas remain relatively under‐researched. Further gaps in the literature emerge that present avenues for future research, namely to: (1) develop a more comprehensive understanding of OI by including diverse perspectives (users, networks, and communities), (2) direct increased attention to OI strategy formulation and implementation, and (3) enhance focus on customer co‐creation and conceptualize “open service innovation.” Marketing (e.g., service‐dominant logic), organizational behavior (e.g., communities of practice), and management (e.g., dynamic capabilities) offer suitable theoretical lenses and/or concepts to address these gaps. 相似文献

M?ngeln in der h?uslichen Pflege pr?ventiv begegnen – Vertrauen ohne Kontrolle, Routine, überforderung oder das Nichtbeachten
des Beziehungsgeflechtes zwischen Pflegenden und Gepflegten führt oft zu Problemen. Der Gesetzgeber verpflichtete deshalb
die Pflegekassen und Tr?gerverb?nde von ambulanten Pflegeeinrichtungen zur Erarbeitung von Richtlinien und standardisierten
Verfahren für die Pflegefachberatung. Leider gibt es bislang keine verbindliche Umsetzung. 相似文献

Umgang mit knappen Ressourcen - Das Schreckgespenst der Rationierung macht sich im Gesundheitswesen breit und beunruhigt Patienten,
Anbieter von Gesundheitsleistungen und den Gesetzgeber gleicherma?en. Pflegende befürchten, selbst Opfer oder Henkersknechte
dieses Ph?nomens zu werden. Sind diese ?ngste begründet? Und – besteht die M?glichkeit zum Gegensteuern? Eine kritische Einsch?tzung

This paper investigates the importance of higher moments of return distributions in capturing the variation of average stock returns for companies listed in the leading S&P US and Australian indices. We find that Australian stocks are more negatively skewed but less leptokurtic than US stocks. As a result, we find that co-skewness plays a more important role in explaining Australian returns while co-kurtosis is consistently influential for US stock returns. We postulate that the differences in results are related to the underlying firm characteristics of the companies in the two indices, where principally the Australian firms are noticeably smaller than their US counterparts and concentrated in a smaller number industry sectors. This implies that for many smaller exchanges around the world higher moment characteristics displayed by the US market may not be applicable. We also show our results are robust to partly explaining average stock returns in the presence of size, value, and momentum effects. 相似文献

In spite of almost 40 years of active enforcement efforts by the EEOC, as well as the strong intervention by the plaintiff bar, the most popular benchmark by which we measure the influence of prejudice on wages paid to female and minority workers has changed very little. This paper maintains that to a large extent this seeming immunity of discriminatory wage gaps to the legal remedies provided by Title VII results from the mismeasurement of those effects. An alternative to the standard Oaxaca decomposition of the wage gap is offered which allows us to put plausible ranges around the true impact of antidiscrimination laws. Not only does this reduce the residual impact of the discrimination that appears to withstand Title VII remedies, it also suggests that the pre‐Title VII impact of discrimination on wages accounted for little of the gap observed at the time of its passage.

Which inequalities among individuals are considered unjust? This paper reports the results of an experiment designed to study distributive choices dealing with arbitrarily unequal initial endowments. In a three-person distribution problem where subjects either know or do not know their endowments, we find impartial behavior to be a stable pattern. Subjects either compensate for initial inequalities fully or not at all in both conditions, and they do so more often when they do not know their endowment than when they know it. Moreover, the type and the size of the good to be distributed also affect the frequency of impartial behavior. 相似文献

Martin Luther urged each town to have a girls' school so that girls would learn to read the Gospel, thereby evoking a surge of building girls' schools in Protestant areas. Using county‐ and town‐level data from the first Prussian census of 1816, we show that a larger share of Protestants decreased the gender gap in basic education. This result holds when using only the exogenous variation in Protestantism due to a county's or town's distance to Wittenberg, the birthplace of the Reformation. Similar results are found for the gender gap in literacy among the adult population in 1871. 相似文献
