Scientific collaboration is a complex phenomenon that improves the sharing of competences and the production of new scientific
knowledge. Social Network Analysis is often used to describe the scientific collaboration patterns defined by co-authorship
relationships. Different phases of the analysis of collaboration are related to: data collection, network boundary setting,
relational data matrix definition, data analysis and interpretation of results. The aim of this paper is to point out some
issues that arise in these different phases, highlighting: (i) the use of local archives versus international bibliographic
databases; (ii) the use of different approaches for setting boundaries in a whole-network; (iii) the definition of a co-authorship
data matrix (binary and weighted ties) and (iv) the analysis and the interpretation of network measures for co-authorship
data. We discuss the different choices that can be made in these phases within an illustrative example on real data which
is referred to scientific collaboration among researchers affiliated to an academic institution. In particular, we compare
global and actor-level network measures computed from binary and weighted co-authorship networks in different disciplines. 相似文献

Research on analyst bias typically identifies affiliation with reference to a subset of the mandates that could give rise to incentives for bias in a multifunction investment bank. This paper develops a new measure of affiliation based upon the UK practice of corporate broking. An advantage of this approach is that affiliation is no longer restricted to isolated equity issuance events as it is an ongoing activity. This research shows that prior US evidence regarding the “Global Settlement” is robust to this new measure and application in the United Kingdom rather than solely the United States. The paper uses a hazard rate methodology focusing on the timeliness of revisions to address selection bias concerns. 相似文献

This article provides new evidence on the contribution of local banking to local economic growth (i.e. at county level – the Italian ‘province’) in Italy. A comprehensive data set is used, which includes control variables for social capital and human capital as well as indicators of the quality of local infrastructures and the production structure of the local economy. A linear within-estimator technique with fixed effects is applied to a modified version of the so-called Barro regression in order to address the well-known econometric issues of reverse causality and estimation bias resulting from unobserved district-specific influences. 相似文献

Entrepreneurial marketing has emerged as a recent perspective within the marketing field, taking the challenges and characteristics of small firms and founding teams into account. Specifically, in the early stages of entrepreneurial marketing, besides potential customers a variety of other stakeholders tend to be in the center of attention. Among these stakeholders, business angels as early-stage investors represent a vital target group. In this paper, we aim to shed light on entrepreneurial marketing in the early phases of new venture creation, in which entrepreneurial firms have an inherent need to market the value of a business opportunity toward potential investors. In particular, we contribute to the literature by introducing the business model as a narrative device for the marketing of early-stage new ventures toward potential business angels. In this regard, the business model is suggested as playing a critical role through making the inherent economic value of a technology explicit. Building on narrative theory, we investigate the role that the business model plays in the decision-making process of 17 business angels. Based on our findings, we propose a model that links the business model to a business angel's interpretation of an investment opportunity and discuss implications for theory and practice. 相似文献

The empirical literature on international trade predicts that internationally involved firms experience a productivity premium when compared to domestic firms. This finding is supported by comparing the unconditional productivity averages or distributions, or regressing the productivity on the international status dummy, controlled for the relevant covariates. In the present paper, we disentangle the distribution of the gross productivity premium from the component that is created by the different structural compositions of the two groups of firms; we can thereby measure the distribution of the net premium that is attributable to internationalisation. To this purpose, we use the quantile decomposition methodology ( Melly, 2005 ). The main results highlight that (i) the net premium is substantially lower than the gross premium and (ii) while the difference in the gross premium is uniform along the entire distribution, the net premium is significant only for the less productive firms. These results are confirmed even if different internationalisation modes are considered (i.e. exports, agreements and commercial penetration) using the domestic firms as baseline. One exception is the net premium for firms enrolled in foreign direct investment and/or offshoring; this premium does not decrease for firms at the top of the productivity distribution. 相似文献

In their seminal paper, Morris and Shin (Amer Econ Rev 92(5): 1521–1534, 2002a) argued that increasing the precision of public information is not always beneficial to social welfare. Svensson (Amer Econ
Rev 96: 448–451, 2006) however has disputed this by saying that although feasible, the conditions for which this was true, were not all that likely.
In that respect, therefore, increasing ‘transparency’ remains most of the times beneficial to social welfare. In this paper,
we extend the Morris and Shin attempt by setting it up as an explicit interactive game between the Central Bank, the objectives
of which we model explicitly, and the private sector. We show that in the absence of costs, both players benefit from transparency
in the manner described previously in the literature, and point the differences in their gains. Following that, we then introduce
the fact that increasing transparency comes at some costs and show how both players face incentives to free ride on each other
as a result. The presence of costs thus alters the way in which greater transparency is attained.

Since 2002, the Institute for Peace Promotion and Injury/Violence Prevention (CISALVA) at the Universidad del Valle, Cali, Colombia and the Colombia Program at Georgetown University have developed and implemented 21 epidemiologically based municipal crime observatories in intermediate-sized municipalities in Colombia. These crime observatories serve as monitoring centres that provide low cost, geo-referenced methods of data collection and analysis, which allow cities to develop more responsive policies and prevention programmes and enhance governance. This article focuses on the methodology employed and lessons learned that may be applicable to similar settings. Worth noting within the results was a significant decrease in homicides after the first year of the programme. Whether or not such results could be attributed to the method or to the nature of the interventions and policy initiatives stemming from it remains open to conjecture. 相似文献

Consumers worldwide are increasingly concerned with sustainable production and consumption. Recently, a comprehensive study ranked 17 countries in regard to their environmentally friendly behaviour among consumers. Brazil was one of the top countries in the list. Yet, several studies highlight significant differences between consumers' intentions to consume ethically, and their actual purchase behaviour: the so‐called ‘Attitude‐Behaviour Gap’. In developing countries, few studies have been conducted on this issue. The objective of this study is therefore to investigate the gap between citizens' sustainability‐related attitudes and food purchasing behaviour using empirical data from Brazil. To this end, Brazilian citizens' attitudes towards pig production systems were mapped through conjoint analysis and their coexistence with relevant pork product‐related purchasing behaviour of consumers was investigated through cluster analysis. The conjoint experiment was carried out with empirical data collected from 475 respondents surveyed in the South and Center‐West regions of Brazil. The results of the conjoint analysis were used for a subsequent cluster analysis in order to identify clusters of Brazilian citizens with diversified attitudes towards pig production systems, using socio‐demographics, attitudes towards sustainability‐related themes that are expected to influence the way they evaluate pig production systems, and consumption frequency of various pork products as clusters' background information. Three clusters were identified as ‘indifferent’, ‘environmental conscious’ and ‘sustainability‐oriented’ citizens. Although attitudes towards environment and nature had indeed an influence on citizens' specific attitudes towards pig farming at the cluster level, the relationship between ‘citizenship’ and consumption behaviour was found to be weak. This finding is similar to previous research conducted with European consumers: what people (in their role of citizens) think about pig production systems does not appear to significantly influence their pork consumption choices. Improvements in the integrated management of this chain would better meet consumers' sustainability‐related expectations towards pig production systems. 相似文献
