Determining Uses and Gratifications for the Internet

Uses and gratifications (U&G) is a media use paradigm from mass communications research that guides the assessment of consumer motivations for media usage and access. It has been used previously in research and decision making related to the promotion of emerging radio and television media. Recent adaptations of U&G research to the Internet are incomplete and have not identified important new Internet‐specific gratifications. This paper empirically derives dimensions of consumer Internet use and usage gratifications among customers of a prominent Internet Service Provider (ISP). Results describe three key dimensions related to consumer use of the Internet, including process and content gratifications as previously found in studies of television, as well as an entirely new social gratification that is unique to Internet use. All three dimensions of gratification are relevant to managing the Internet as a commercial medium, and measures developed from the gratification profiles identified here can serve as trait‐valid scales in future Internet and e‐commerce research.     

Evaluating the Deming Management Model of Total Quality in Services*

This article uses the Deming management model developed by Anderson et al. (1994b) as an initial template to analyze total quality in services. While the literatures addressing quality management have developed separately for products and services, the founders of total quality portrayed this management philosophy as universally oriented. Our study first replicates two earlier studies that tested the Deming management model in manufacturing industries. Using hospitals as our unit of analysis, we realized findings similar to the earlier manufacturing studies. Next, we used contributions from the MBNQA literature to test an enhanced model. Our subsequent findings support the MBNQA concept that “leadership drives the system that creates results” and provides evidence of the ubiquitous importance of leadership for ensuring the success of a quality improvement program. Finally, an anomaly of this study and those published earlier is the inability to find support for the relationship between continuous improvement and customer satisfaction. Integrating the substantial work in the service quality literature focused on customer satisfaction measurement is recommended to future researchers to help resolve this issue and further enhance the model.     

Global innovation performance: Strategic challenges for multinational corporations

In the emerging knowledge economy many companies are forced to access globally dispersed technological and market knowledge to maintain their competitive advantage. A conceptual model is presented to analyze the relationship between the globalization of the innovation function and firm performance. Longitudinal data from 10 multinational companies are used to support the proposed model. The analysis concludes that the relationship between global innovation reach and firm performance is concave and time lagged. The results suggest the strategic importance of globalization decisions. The managerial implications are structured in five distinctive strategic challenges to successfully manage global innovation.     

Application of Correspondence Analysis in the Assessment of Mine Tailings Dam Breakage Risk in the Mediterranean Region

A new statistical approach for preliminary risk evaluation of breakage in tailings dam is presented and illustrated by a case study regarding the Mediterranean region. The objective of the proposed method is to establish an empirical scale of risk, from which guidelines for prioritizing the collection of further specific information can be derived. The method relies on a historical database containing, in essence, two sets of qualitative data: the first set concerns the variables that are observable before the disaster (e.g., type and size of the dam, its location, and state of activity), and the second refers to the consequences of the disaster (e.g., failure type, sludge characteristics, fatalities categorization, and downstream range of damage). Based on a modified form of correspondence analysis, where the second set of attributes are projected as "supplementary variables" onto the axes provided by the eigenvalue decomposition of the matrix referring to the first set, a "qualitative regression" is performed, relating the variables to be predicted (contained in the second set) with the "predictors" (the observable variables). On the grounds of the previously derived relationship, the risk of breakage in a new case can be evaluated, given observable variables. The method was applied in a case study regarding a set of 13 test sites where the ranking of risk obtained was validated by expert knowledge. Once validated, the procedure was included in the final output of the e-EcoRisk UE project (A Regional Enterprise Network Decision-Support System for Environmental Risk and Disaster Management of Large-Scale Industrial Spills), allowing for a dynamic historical database updating and providing a prompt rough risk evaluation for a new case. The aim of this section of the global project is to provide a quantified context where failure cases occurred in the past for supporting analogue reasoning in preventing similar situations.     

A Newsvendor Who Chooses Informational Effort

We study a newsvendor who can acquire the services of a forecaster, or, more generally, an information gatherer (IG) to improve his information about demand. When the IG's effort increases, does the average ex ante order quantity rise or fall? Do average ex post sales rise or fall? Improvements in information technology and in the services offered by forecasters provide motivation for the study of these questions. Much depends on our model of the IG and his efforts. We study an IG who sends a signal to a classic single‐period newsvendor. The signal defines the newsvendor's posterior probability distribution on the possible demands and the newsvendor uses that posterior to calculate the optimal order. Each of the possible posteriors is a scale/location transform of the same base distribution. When the IG works harder, the average scale parameter drops. Higher IG effort is always useful to the newsvendor. We show that there is a critical value of order cost. For costs on one side of this value more IG effort leads to a higher average ex ante order and for costs on the other side to a lower average order. But for all costs, more IG effort leads to higher average ex post sales. We obtain analogous results for a “regret‐averse” newsvendor who suffers a penalty that is a nonlinear function of the discrepancy between quantity ordered and true demand.     

The research frontier in corporate governance

In this paper we attempt to identify the research frontier in corporate governance using three different approaches: (1) what challenges does the financial crisis 2007–2009 pose for corporate governance research? We show that the financial crisis is a huge natural experiment which has exposed gaps in our knowledge of corporate governance and is likely to lead of a rethink of central concepts like shareholder value, debt governance, and management incentives (2) what do we know and what do we need to how about the impact of national institutions on corporate governance? (3) What research questions are raised by a focus on current corporate governance practices?     

Estimating the Population Survival Function Using Additional Information Recorded Over Time: a Filter Based Approach

Survival studies often collect information about covariates. If these covariates are believed to contain information about the life-times, they may be considered when estimating the underlying life-time distribution. We propose a non-parametric estimator which uses the recorded information about the covariates. Various forms of incomplete data, e.g. right-censored data, are allowed. The estimator is the conditional mean of the true empirical survival function given the observed history, and it is derived using a general filtering formula. Feng & Kurtz (1994) showed that the estimator is the Kaplan–Meier estimator in the case of right-censoring when using the observed life-times and censoring-times as the observed history. We take the same approach as Feng & Kurtz (1994) but in addition we incorporate the recorded information about the covariates in the observed history. Two models are considered and in both cases the Kaplan–Meier estimator is a special case of the estimator. In a simulation study the estimator is compared with the Kaplan–Meier estimator in small samples.     

Of Polls, Mountains: U.S. Journalists and Their Use of Election Surveys

Polls are a prominent feature of U.S. election news coverage.Although polls are used to explain voter opinion, they are employedmostly to fuel horse-race coverage and to craft images consistentwith the candidates’ positions in the race. Moreover,U.S. journalists sometimes misinterpret polls by slighting thepossibility that changes in candidate preference are the resultof survey error rather than real change. On balance, U.S. journalists’dependence on polls adversely affects the quality of Americanelection coverage.     

A Tale of Political Trust in American Cities

This study performs a multilevel analysis of public trust inlocal government. We develop and test competing hypotheses aboutthe contextual and individual-level sources of local politicaltrust. The results show that citizens’ trust in localgovernment is shaped not only by individual-level factors butalso by city-level factors such as income inequality, ideologicalpolarization, political institutions, racial fractionalization,and size of population. Cross-level analysis further indicatesthat the effects of race on local political trust are conditionedby cities’ systems of political representation.     

Career Development in Middle Childhood: A Qualitative Inquiry

The purpose of this investigation was to explore childhood career development by examining 4th‐ and 5th‐grade students' career and self‐awareness, exploration, and career planning. Responses to written assignments provided qualitative data for analysis. Written narrative data were analyzed using consensual qualitative research methods as described by C. E. Hill, B. J. Thompson, and E. N. Williams (1997). Consistent with theory (D. Super, 1990), children's reflections on prominent career tasks and influences revealed 8 of the 9 (all but curiosity) dimensions of childhood career development as outlined by Super. In addition, participants described their conceptions of work, a domain not explicitly articulated by Super and worthy of further inquiry.
