An exploratory survey was conducted to determine if there are differences in ethical decisions by business students based upon cultural backgrounds. Students' responses to a vignette concerning advertising of cigar products in a variety of different media provided evidence of significant cultural differences between three groups of students from different geographical locations within the United States. This article suggests that the presumption that an individuals ethical beliefs and behaviors do not change after childhood may be in error.
. This paper reports the preliminary results from a semester-long ethics project at an AACSB accredited, regional comprehensive undergraduate school. This project culminated in an Ethics Awareness Week, which highlight a case study of the controversial EverQuest® multi-player online game. Issues of project planning and design are outlined, the dynamics of a business program-wide approach to ethics are social responsibility are presented, student survey results are presented and analyzed, and issues related to ongoing research are discussed. Nonparametric survey results indicate (...) that the greatest effect in student’s self reported enhanced understanding and interest in issues of business ethics is present when multiple pedagogical methods, e.g., case studies, lectures, assignments, and an Oxford-style debate, are applied by a number of faculty members over an extended time period. The paper concludes with a discussion of future research issues as well as a series of prescriptions for planning, organizing, and implementing such an extended activity. (shrink)
In homes, schools, and workplaces, women and men are often separated in ways that sustain gender stratification by reducing women's access to socially valued knowledge. The fact that these spatial arrangements may be imperceptible increases their power to reproduce prevailing status differences. I use cross-cultural and historical examples to illustrate that the more pronounced the degree of spatial gender segregation, the lower is women's status relative to men's. The advantages of such a spatial perspective are its interdisciplinary foundations and its (...) creation of avenues for change. (shrink)
Understanding the linkages between grain mineralogy and diagenetic and sedimentary processes enhances the reliability of petrophysical models to predict reservoir deliverability from permeability. Petrographic data within well-defined depositional facies reveal the diagenetic evolution of porosity-permeability relationships. Formation evaluation methods relying solely on petrophysical rock typing are seriously limited when predicting ultimate reservoir performance in complex pore structures. The Almond Formation, Wyoming, is characterized by three depositional facies associations — shoreface, deltaic, and fluvial-coastal plain — which present three distinctive porosity-permeability trends. (...) Textural features resulting from depositional processes, such as grain size and sorting, vary little between facies associations, yet permeability can vary by up to four orders of magnitude for the same porosity value. Differences between petrophysical facies are primarily driven by diagenetic effects on different framework grain compositions. Therefore, the main difference between the facies associations is diagenetic, due to provenance and transport mechanisms. The characterization of depositional and diagenetic controls on pore geometry allows the narrowing of uncertainty in absolute permeability prediction. We have quantified the relationship between depositional facies, with their specific mineral composition and diagenetic overprint, and the steepness functions in porosity-permeability space. This analysis allowed us to effectively reduce the uncertainty in the prediction of initial gas production from wireline logs. (shrink)
The Upper Jurassic Haynesville Shale Formation in the East Texas Basin, North America, is a black, organic-rich, calcareous mudstone that lies below the Bossier Shale and above the Cotton Valley Limestone. The reservoir quality was controlled by primary depositional process and secondary diagenesis. The best lithology type in terms of drilling, completion, and production is the organic-rich, silty calcareous mudstone with low clay content. The studied well traversed the entire Haynesville Formation with the objective to assess the production potential of (...) this formation. We acquired open-hole, triple-combo logging while drilling logs, two types of production logs, and regional microseismic data. Postdrill log modeling confirmed that the horizontal well stayed on the planned trajectory, based on the log correlation between the horizontal and offset wells. Log modeling demonstrated that the LWD resistivity logs in horizontal wells are subject to resistivity anisotropy and polarization horn effects. We integrated the production log results with the open-hole, log formation evaluation and mineralogy-based brittleness index, to understand the static reservoir properties and dynamic inflow performance. The open-hole and cased-hole logs consistently showed that the “rabbit ears” interval at the base of the Upper Haynesville and the top interval of the Upper Haynesville were excellent lateral well-landing zones for best production. We combined microseismic data with production log data and found that the effective stimulated rock volume by hydraulic fracturing was mostly concentrated in the top interval of the Upper Haynesville and the “rabbit ears” interval at the base of the Upper Haynesville. The study demonstrated that a multidisciplinary approach was necessary in determining the best zone to land Haynesville horizontal wells. (shrink)
