Abstract

Aims

To characterize a US population of patients with irritable bowel syndrome with constipation (IBS-C) or chronic idiopathic constipation (CIC) using CONTOR, a real-world longitudinal research platform that deterministically linked administrative claims data with patient-reported outcomes data among patients with these conditions.  相似文献

We investigate the use of unit (i.e., package) initial public offerings by Australian industrial firms and conclude that their use reflects their role as a signaling mechanism (Chemmanur and Fulghieri, 1997), as distinct from the agency–cost explanation offered by Schultz (1993). From a sample of 394 IPOs between 1976 and 1994, the 66 firms making unit offerings are typically riskier, use less prestigious underwriters and have a lower level of retained ownership than other IPO firms. While these results are also consistent with Schultz's agency cost explanation, other results we report are not. We find no difference in underpricing etween unit IPOs and other IPO firms, nor are there any significant differences in the planned uses of proceeds reported in the prospectus, post–listing failure rates or secondary equity offerings of the type predicted by Schultz. We do however, report evidence consistent with a prediction unique to the signaling explanation. After controlling for the level of ownership retained by insiders, the proportion of firm value sold as warrants is increasing in IPO firms' riskiness.  相似文献

The present study identifies a two-step flow process of communication mediated by technological gatekeepers for scientific and technical fields characterized by dynamic information environments. Peer identification and a supervisory recognition of the phenomenon validate the gatekeeper finding. Certain characteristics of this study differ from previous research. The external communication needs of military in-house researchers are mitigated greatly by the infusion of technical information into the laboratory which is a part of the everyday activities of the organization. Gatekeepers are differentiated by topic and not the media monitored. Finally, the gatekeeper phenomenon is implicitly recognized, even though the development may be spontaneous; development that results because either the formal media leave a void in information needs or that engineers are not trained in the use of the formal information sources. In either case, the technological gatekeeper is a natural response to an information need.  相似文献

Softlifting: Exploring Determinants of Attitude   总被引:2,自引:0,他引:2  
Softlifting, or the illegal duplication of copyrighted software by individuals for personal use, is a serious and costly problem for software developers and distributors. Understanding the factors that determine attitude toward softlifting is important in order to ascertain what motivates individuals to engage in the behavior. We examine a number of factors, including personal moral obligation (PMO), perceived usefulness, and awareness of the laws and regulations governing software acquisition and use, along with facets of personal self-identity that may play a role in the development of attitudes and therefore intentions regarding this behavior. These factors are examined across multiple settings expected to be pertinent to our survey respondents: home, work and school. Personal moral obligation and perceived usefulness are significant predictors of attitude across all settings. Past behavior is a significant predictor of intention across all settings, and a significant predictor of attitude in the home setting. We find evidence that awareness of the law causes a less favorable evaluation of softlifting in the school setting only, but has little effect in the home and work settings. As in previous studies, attitude is a significant predictor of intent. We do not find indications that one’s personal self-identity influences one’s attitude towards the behavior and the intention to perform it, except in the case of legal identity, where marginally significant effects are found in the work environment.
