The US construction industry annually experiences a relatively high rate of fatalities and injuries; therefore, improving safety practices should be considered a top priority for this industry. Modular/prefabricated building construction is a construction strategy that involves manufacturing of the whole building or some of its components off-site. This research focuses on the safety performance of the modular/prefabricated building construction sector during both manufacturing and on-site processes. This safety evaluation can serve as the starting point for improving the safety performance of this sector. Research was conducted based on Occupational Safety and Health Administration investigated accidents. The study found 125 accidents related to modular/prefabricated building construction. The details of each accident were closely examined to identify the types of injury and underlying causes. Out of 125 accidents, there were 48 fatalities (38.4%), 63 hospitalized injuries (50.4%), and 14 non-hospitalized injuries (11.2%). It was found that, the most common type of injury in modular/prefabricated construction was ‘fracture’, and the most common cause of accidents was ‘fall’. The most frequent cause of cause (underlying and root cause) was ‘unstable structure’. In this research, the accidents were also examined in terms of corresponding location, occupation, equipment as well as activities during which the accidents occurred. For improving safety records of the modular/prefabricated construction sector, this study recommends that future research be conducted on stabilizing structures during their lifting, storing, and permanent installation, securing fall protection systems during on-site assembly of components while working from heights, and developing training programmes and standards focused on modular/prefabricated construction. 相似文献

This paper examines the emergence of hyperinflation in a small open economy with a fixed exchange rate from a post Keynesian perspective. Three variables play key roles: distributive conflict, external debt, and expectations about the exchange rate. First, we propose a short-run Kaleckian macro model. Then, we study the long-run behavior of the model by endogenizing the price level and foreign indebtedness. We conclude that the existence of expectations about the nominal exchange rate is crucial to explaining the emergence of hyperinflation. 相似文献

Credit default swaps (CDS) are similar to out-of-the-money put options in that both offer a low cost and effective protection against downside risk. This study investigates whether put option-implied volatility is an important determinant of CDS spreads. Using a large sample of firms with both CDS and options data, we find that individual firms’ put option-implied volatility dominates historical volatility in explaining the time-series variation in CDS spreads. To understand this result, we show that implied volatility is a more efficient forecast for future realized volatility than historical volatility. More importantly, the volatility risk premium embedded in option prices covaries with the CDS spread. These findings complement existing empirical evidence based on market-level data. 相似文献

This article documents the popularity of five types of trail-based recreation relative to other forms of recreation that tourists frequently participate in on their trips; identifies these trail users’ cross-participation in other outdoor recreation activities; and profiles the travel behaviour, media habits, trip planning behaviour, and demographic and socioeconomic characteristics of day hikers and snowmobilers as two particularly large trail user segments. Findings are based on data from a household telephone survey conducted in Michigan, surrounding states, and Ontario, Canada. Hiking/backpacking was found to be the most popular natural resource-based recreation activity that respondents participated in on pleasure trips taken during the past 12 months; other forms of trail-based recreation were significantly less popular; mountain bikers participated in nature-oriented recreation activities in Michigan at levels that were similar to those of hikers/backpackers; and snowmobiling appeared to be the focus of most pleasure trips on which this activity occurred, in contrast to day hiking, which appeared to be more of an ancillary pursuit. 相似文献

It is clear that customer-to-customer contact through informal social networking and more formal company-sponsored platforms, such as discussion forums, is an increasingly integral element in building brand communities. There are many benefits to this interaction, such as nurturing brand champions and ‘super users,’ and reduced service costs through customer-to-customer solutions for product problems. However, there are also hazards inherent in these largely unregulated communities, such as the potential damage of widely spread negative information, which may be based on fact or on malicious intent. Herein, we summarize the results of several years of research examining these communities in an attempt to understand why they succeed, what benefits can be extracted from them, and—in particular—how negative information emerging in these environments can be strategically managed. Based on a series of quantitative and qualitative studies, we identified several key drivers of online brand community success (i.e., intervention, conversion, value creation, and harvesting) and the different combinations of community players who must collaborate to achieve such success. Delving more deeply into the issue of negative information management, we find that the topic being discussed (i.e., core versus augmented product) and the validity of the claim greatly influence a firm's appropriate strategic response. Throughout this article, we offer managerial guidance on the most effective ways to develop primary brand communities that encourage loyalty, purchases, and positive word of mouth. 相似文献

The predictions of growing consumer power in the digital age that predated the turn of the century were fueled by the rise of the Internet, then reignited by social media. This article explores the intersection of consumer behavior and digital media by clearly defining consumer power and empowerment in Internet and social media contexts and by presenting a theoretical framework of four distinct consumer power sources: demand-, information-, network-, and crowd-based power. Furthermore, we highlight technology's evolutionary role in the development of these power sources and discuss the nature of shifts in power from marketers to consumers in terms of each source. The framework organizes prior marketing literature on Internet-enabled consumer empowerment and highlights gaps in current research. Specific research questions are elaborated for each source of power outlining the agenda for future research areas. 相似文献

Firms with central boards of directors earn superior risk-adjusted stock returns. A long (short) position in the most (least) central firms earns average annual returns of 4.68%. Firms with central boards also experience higher future return-on-assets growth and more positive analyst forecast errors. Return prediction, return-on-assets growth, and analyst errors are concentrated among high growth opportunity firms or firms confronting adverse circumstances, consistent with boardroom connections mattering most for firms standing to benefit most from information and resources exchanged through boardroom networks. Overall, our results suggest that director networks provide economic benefits that are not immediately reflected in stock prices. 相似文献

Marketers are now willing to go anyplace they can find a captive audience to espouse the virtues of their products. The success of the “buzz” marketing approach is linked to the consumer being lured into doing the advertising by spreading the message to others. This study compares students’ responses to a traditional advertising and a buzz approach. Using a factor analysis to identify variables, the results show that subjects perceive a buzz approach to be more influential than a traditional advertising. However, they do not perceive a buzz approach to be authentic. This finding is consistent with practitioners’ argument that, although a buzz approach may be effective in the short-term, once consumers recognize its selling intent, the program may have a “boomerang effect.” 相似文献
