This article considers processes of urban development within the context of mega‐event preparations in Rio de Janeiro. We begin with a brief overview of these development processes, highlighting their connections to political and economic change in recent years. Proponents of these mega‐event‐led initiatives argue that Rio is undergoing a period of inclusive growth and integration: a perspective we call here a ‘post‐Third‐World city' narrative of urban renewal. Critics, however, contend that urban officials are harnessing mega‐events (e.g. the 2014 World Cup and the 2016 Olympic Games) to push forward a neoliberal agenda of socially unjust policies benefiting the interests of capital and marginalizing the city's poor and especially its favelas (i.e. the ‘city‐of‐exception' thesis). In this article we explore the insights of these two perspectives and consider why they have grown popular in recent years. Though we side generally with the city‐of‐exception thesis, we argue that important geographic and historical particularities must also be accounted for. Without carefully situating analytical perspectives empirically—in particular, cases in which theoretical models are drawn from European and North American contexts—urban researchers risk concealing more than they reveal in analyses of rapidly developing countries like Brazil.  相似文献

This paper uses data on wage and salary workers in Australia in 1993 to examine the relation between computer knowledge and earnings. A unique feature of the data set that is used is detailed information on the types and levels of computer skills possessed by individual workers. The main objectives of the study are to contribute to understanding the magnitude and sources of the relation between computer knowledge and earnings. Similar to existing research it is found that there is a large and significant return to computer knowledge, but that the magnitude of the return is substantially reduced in regressions that include detailed occupation controls. Using the detailed information on workers’ computer skills the main finding is that earnings are significantly positively related to the number of types of skills and average level of skills possessed by a worker.  相似文献

As supply chains become more complex, firms face increasing risks of supply disruptions. The process through which buyers make decisions in the face of these risks, however, has not been explored. Despite research highlighting the importance of behavioral approaches to risk, there is limited research that applies these views of risk in the supply chain literature. This paper addresses this gap by drawing on behavioral risk theory to investigate the causal relationships amongst situation, representations of risk, and decision-making within the purchasing domain. We operationalize and explore the relationship between three representations of supply disruption risk: magnitude of supply disruption, probability of supply disruption, and overall supply disruption risk. Additionally, we draw on exchange theories to identify product and market factors that impact buyers’ perceptions of the probability and magnitude of supply disruption. Finally, we look at how representations of risk affect the decision to seek alternative sources of supply. We test our model using data collected from 223 purchasing managers and buyers of direct materials. Our results show that both the probability and the magnitude of supply disruption are important to buyers’ overall perceptions of supply disruption risk. We also find that product and market situational factors impact perceptions of risk, but they are best understood through their impact on perceptions of probability and magnitude. Finally, we find that decisions are based on assessments of overall risk. These findings provide insight into the decision-making process and show that all three representations of risk are necessary for fully understanding risky decision-making with respect to supply disruptions.  相似文献

While policy-makers understand the vast benefits of publicly funded and not-for-profit research, governance practitioners have the difficult task of defining processes that can best foster high performance for science and technology (S&T) labs not primarily driven by profits. This qualitative study develops a new taxonomy based on two dimensions, the nature of the funding relationship between the parent organisation and the S&T lab and the degree of interdependence between the lab's research units. We discuss the dynamics uncovered for each of the four archetypes with illustrative cases and argue that high-performance governance of S&T labs requires an internal coherence linking the processes of planning, funding and performance evaluation.  相似文献

We examine the relation between the use of collateral and financial reporting conservatism for a sample of Chinese firms. In the absence of flexibility in risk pricing through interest rates and strong contract enforcement in China, we find that lenders reduce collateral requirements from more conservative borrowers and that this negative relation is significantly moderated by borrowers’ poor credit quality and low asset tangibility. Our finding that conservatism can result in a tangible benefit in the form of lower collateral requirements indicates that lenders value financial reporting conservatism. However, the benefit from financial reporting conservatism is muted as lenders become more concerned about borrowers’ default risk or ability to pledge tangible assets as collateral against loans.  相似文献

We find that the Bear Stearns rescue in March 2008 elicited a neutral or moderately favorable impact on bond prices. Conversely, we find that the Lehman Brothers failure (combined with news about Merrill Lynch and American International Group) in September 2008 elicited a pronounced negative impact. Bond prices of financial firms suffered more than bonds of nonfinancial firms following the Lehman failure. Our multivariate analysis shows that bonds issued by financial institutions that were previously presumed to be protected (based on bond rating and firm size) suffered more pronounced losses in response to the Lehman failure.  相似文献

The present research develops and tests a theory explaining how customers respond to failed service recoveries (i.e., double deviations). This work offers three novel and important conclusions. First, inferences about a firm's motive (negative vs. positive) mediate the impact of perceptions of the double deviation (i.e., severity, blame, and fairness) on resulting outcomes (i.e., customer anger, desire for revenge, and desire for reconciliation). Second, when inferred motive is positive, desire for reconciliation overwhelms desire for revenge, leading customers to choose more reparatory than retaliatory behaviors. Third, following a double deviation, firms that both compensate and apologize to customers can change customers’ inferred motives from negative to positive, leading customers to desire more reconciliation than revenge, and engage in more reparatory than retaliatory behaviors. These studies demonstrate that, contrary to common wisdom, customers do not always respond negatively to a double deviation, and firms still have a “second chance” following a failed recovery.  相似文献

We find that the announcement of a merger withdrawal elicits negative industry effects on average, which reflect a partial reversal of the favorable industry effects that had previously occurred at the time of the merger proposal. The mean reversal is about 35% of the original favorable industry effect at the time of the merger announcement. This result for the mean effect is opposite of that found by Akhigbe et al. (2000). When we break our sample into sub-periods, we find that industry effects are substantially weaker in a more recent sub-period beyond the sample period used by Akhigbe et al. (2000). We also find that the industry effects are more negative when the share price response of the target at the time of the announced withdrawal is weaker. Whether the negative impact on the target is attributed to either a reduced likelihood of takeover or weaker industry prospects, it carries over to industry rivals.  相似文献

Without complete and accurate status information, a project manager’s ability to monitor progress, allocate resources effectively, and detect and respond to problems is greatly diminished, and this can lead to impaired project performance. Many different factors can contribute to intentional misreporting of status information by project members to the project manager. In this study, the impact of organizational ethical climate was assessed through the analysis of responses from 228 project members drawn from a variety of ongoing information systems projects. Our results revealed that project members who perceived their organization to be one in which rules are followed strictly tended to misreport less, while those operating in an environment dominated by personal self-interest tended to misreport more. Somewhat surprisingly, the existence of a caring, team-spirited environment did not appear to have an impact on misreporting behaviors. Implications for researchers and project managers are discussed.  相似文献
