The Yield Shift Theory of Satisfaction and Its Application to the IS/IT Domain

Abstract: Information Systems/Information Technology (IS/IT) satisfaction is a key indicator of IS/IT success. For IS professionals and providers, satisfaction is critical throughout the life of a system because dissatisfied stakeholders can derail implementation, discontinue using an important system, erode IS/IT budgets, or even transfer their entire IT infrastructure to a different organization. The IS literature offers several perspectives on satisfaction, but none yet accounts fully for known satisfaction phenomena. We identify ten observed satisfaction effects, and summarize six existing models for satisfaction, identifying their merits, and the limits of their explanatory power. We then advance Yield Shift Theory (YST), a new causal theory of the satisfaction response that offers a more complete explanation of the phenomenon. YST derives two propositions from five assumptions to propose that the yield for a given goal is a function of the utility one ascribes to moderated by the likelihood one assesses of its attainment, and that variations in the satisfaction response are a curvilinear function of shifts in yield for an individual’s active goal set. We argue the falsifiability and scientific utility of the theory, discuss its relevance to IS/IT, and suggest directions for future research.

Communication and connectedness in the classroom: Development of the connected classroom climate inventory

Abstract: This article presents the rationale for and development of the Connected Classroom Climate Inventory (CCCI) designed to measure connectedness among students in the university classroom. The original inventory contained 20 items plus four validity items. Based on factor analysis and reliability analysis, two of the original 20 items were dropped from consideration. The resulting 18‐item CCCI scale was found to contain a single factor, to have an overall reliability of alpha = .94, and to show initial evidence of validity. The CCCI showed no scale score differences among class sections or based on teacher/student sex. These findings and implications for future communication research are discussed.

Dimensions of Cyber-Attacks: Cultural, Social, Economic, and Political

Abstract: Essential systems providing water, electricity, healthcare, finance, food, and transportation are now increasingly software dependent, distributed, and interconnected. The detrimental consequences of this growing dependence become apparent during times of political conflict, social instability, and other traumatic events. The Internet has made information exchange easier and more efficient, but it has also created a new space in which criminals and terrorists can operate almost undetected. No longer is modern human conflict confined to the physical world; it has spread to cyberspace. Cyberspace is a massive socio technical system of systems, with a significant component being the humans involved. Current anomaly detection models focus primarily on analyzing network traffic to prevent malicious activities, but it has been shown that such approaches fail to account for human behaviors behind the anomalies. Evidence is growing that more cyber-attacks are associated with social, political, economic, and cultural (SPEC) conflicts. It is also now known that cyber-attackers' level of socio-technological sophistication, their backgrounds, and their motivations, are essential components to predicting, preventing, and tracing cyber-attacks. Thus, SPEC factors have the potential to be early predictors for outbreaks of anomalous activities, hostile attacks, and other security breaches in cyberspace.

Postfledging survival and movement in dickcissels (spiza americana): implications for habitat management and conservation

Abstract: When land managers incorporate the habitat needs of grassland birds into their planning, they typically rely on management recommendations based on habitat use by adults during nesting. Habitat requirements for other critical life stages are seldom known and may differ from those of nesting adults. Using radio-telemetry, we examined survival and habitat use by juvenile Dickcissels (Spiza americana) during the postfledging period. In 2003 and 2004, we monitored 60 fledgling Dickcissels for ≤30 days after they left the nest. Mortality rates were highest during the first week after leaving the nest, and only 33% of the fledglings survived the first four weeks after leaving the nest. Estimated mean survival times were 16.9 ± 1.6 days after birds left the nest. In both years, fledgling survival was positively associated with dense vertical and horizontal structure of forbs at nests. Survival tended to be positively associated with vertical grass density on adult territories and negatively associated w...

Ankle injuries and ankle strength, flexibility, and proprioception in college basketball players.

Abstract: Objective: To determine if ankle muscular strength, flexibility and proprioception can predict ankle injury in college basketball players and to compare ankle injury rates in female and male players. Design and Setting: In this prospective, correlational study, subjects were tested at the start of the competitive season for ankle joint muscle strength, flexibility, and proprioception. The first ankle injury for each subject was recorded on an injury report form, and the data were analyzed to determine if any of these preseason measurements predicted future injury. The setting was a competitive 9-week season for four women's and four men's college basketball teams. Subjects: A convenience sample of 31 female and 11 male college basketball players. Measurements: Subjects were tested for ankle dorsiflexion range of motion, various measures of ankle proprioception, and isokinetic peak torque of ankle dorsiflexion-plantar flexion and eversion-inversion at 30°/sec and 180°/sec before the start of the conference basketball seasons. Data were analyzed using a series of multiple regression equations to determine the variance in ankle injury attributed to each variable. Results: Various measures of proprioception predicted left ankle injury in all subjects (p < .05), while ankle strength and flexibility measures failed to account for additional variance. There was no statistically significant difference in ankle injury rate between women and men. Conclusions: Ankle joint proprioceptive deficits can be used to predict ankle injury, but further research is needed to identify other sources of variance. In our study, ankle injury rate was similar in female and male college basketball players.
