Are Citations to Academic Journal Articles a Measure of Quality or Something Else? An Exploratory Analysis with Emphasis on Design Science and IS Technical Research

One pervasive belief about scholarly citations that underlies several studies appearing in the IS literature is that the number ofcitations to a paper reflects the quality of the study. For example, a paper that receives 200 citations is perceived as havinghigher quality than another study that receives 50 citations. While most experts acknowledge that there are other factors thatdrive citations, such as the number of years a paper was available to be cited – or possibly “gaming” of citations by authorswho cite themselves frequently (author self-citations) or over-zealous editors who incent prospective authors to cite theirjournals (journal self-citations), there is an underlying assumption that, barring such unscrupulous behavior, citations are ameasure of research quality. This paper critically examines this assumption using a validated typology identifying 13 distinctsubject areas that characterize IS research. Results show that papers on some topics (e.g., IT adoption and use; newmeasurement development and validation) consistently receive more citations than average – while some topics consistentlyreceive below-average citation rates (e.g., IS development; IT project/risk management). Unless one assumes that all paperson a given topic are consistently of higher quality than all papers on other topics, our data suggest that a key driver ofcitations are the subject area of the study and, in turn, the size of the research community that conducts research on the topic

Ixodid ticks of impala (Aepyceros melampus) in Swaziland: effect of age class, sex, body condition and management

Five species of ixodid ticks, Amhlyomma hebraeum, Boophilus decoloratus, Rhipicephalus appendiculatus, R. evertsi evertsi and R. muehlensi, were commonly collected from impala (Aepyceros melampus) in the Mlawula-Mbuluzi-Simunye Nature Reserve and Protected Area complex in north-eastern Swaziland. The prevalence and apparent intensity of infestation of most tick species was greater on yearlings (13-24 months of age) and adults (> 24 months) than on lambs (≤12 months), and on adult males than on adult females. The packed cell volume and marrow dry weight were lower in impala infested with A. hebraeum, and in lambs and adults with moderate to heavy loads of R. muehlensiand/or R. appendiculatus. The age and sex patterns of tick infestation were probably determined by both body condition and host behaviour. The prevalence and apparent intensity of infestation of most tick species was greater in the unmanaged, densely populated area of the reserve than in the managed area from which impala had been culled. This trend was consistent in all months, and in all age classes

Analyzing IT Outscoring Relationships as Alliances among Multiple Clients and Vendors

As the business environment become more uncertain and competitive, many organizations are seeking ways to gain economic efficiency and share in business and technology risk. Despite wide differences in the reference disciplines applied to outsourcing research, the vast majority of it assumes a one-to-one relationship between the client and the outsourcing vendor. This paper examines the economic, strategic, and organizational issues involved in IT outsourcing when more complex arrangements are considered - such as multi-vendor alliances, co-sourcing, and complex multi-vendor, multi-client relationships. In this paper, we identify a taxonomy of four classes of outsourcing relationships (based on how many clients and vendors are involved in the outsourcing relationship, and illustrate each with recent business examples. Grounded in this taxonomy, we develop a theoretical framework that identifies both enabling and constraining forces that may influence client firms in choosing among the four types of outsourcing relationships. This paper provides insights regarding how the variations in the nature of these outsourcing relationships may shape the benefits and risks be achieved from outsourcing, as well as the ongoing complexity of managing outsourcing relationships.Information Systems Working Papers Serie

Towards a deeper understanding of system usage in organizations: A multi-level perspective

The objective of this paper is to contribute towards a deeper understanding of system usage in organizations by examining its multilevel nature. Past research on system usage has suffered from a levels bias, with researchers studying system usage at single levels of analysis only, e.g., the individual, group, or organizational level. Although single-level research can be useful, we suggest that studying organizations one level at a time will ultimately lead to an unnatural, incomplete, and very disjointed view of how information systems are used in practice. To redress this situation, we draw on recent advances in multilevel theory to present system usage as a multilevel construct and provide an illustration for what it takes for IS researchers to study it as such. The multilevel perspective advanced in this article offers rich opportunities for theoretical and empirical insights and suggests a new foundation for in-depth research on the nature of system usage, its emergence and change, and its antecedents and consequences

The Impact of Perceived Subgroup Formation on Transactive Memory Systems and Performance in Distributed Teams

With distributed teams becoming increasingly common in organizations, improving their performance is a critical challenge for both practitioners and researchers. This research examines how group members\u27 perception of subgroup formation affects team performance in fully distributed teams. The authors propose that individual members\u27 perception about the presence of subgroups within the team has a negative effect on team performance, which manifests itself through decreases in a team\u27s transactive memory system (TMS). Using data from 154 members of 41 fully distributed teams (where no group members were colocated), the authors found that members\u27 perceptions of the existence of subgroups impair the team\u27s TMS and its overall performance. They found these effects to be statistically significant. In addition, decreases in a group\u27s TMS partially mediate the effect of perceived subgroup formation on team performance. The authors discuss the implications of their findings for managerial action, as well as for researchers, and they propose directions for future research

Planning Ahead: Object-Directed Sequential Actions Decoded from Human Frontoparietal and Occipitotemporal Networks.

Object-manipulation tasks (e.g., drinking from a cup) typically involve sequencing together a series of distinct motor acts (e.g., reaching toward, grasping, lifting, and transporting the cup) in order to accomplish some overarching goal (e.g., quenching thirst). Although several studies in humans have investigated the neural mechanisms supporting the planning of visually guided movements directed toward objects (such as reaching or pointing), only a handful have examined how manipulatory sequences of actions-those that occur after an object has been grasped-are planned and represented in the brain. Here, using event-related functional MRI and pattern decoding methods, we investigated the neural basis of real-object manipulation using a delayed-movement task in which participants first prepared and then executed different object-directed action sequences that varied either in their complexity or final spatial goals. Consistent with previous reports of preparatory brain activity in non-human primates, we found that activity patterns in several frontoparietal areas reliably predicted entire action sequences in advance of movement. Notably, we found that similar sequence-related information could also be decoded from pre-movement signals in object- and body-selective occipitotemporal cortex (OTC). These findings suggest that both frontoparietal and occipitotemporal circuits are engaged in transforming object-related information into complex, goal-directed movements

Measurement of the ΔS=-ΔQ Amplitude from K_(e3)^0 Decay

We have measured the time distribution of the π^+e^-ν and π^-e^+ν modes from initial K^0's in a spark-chamber experiment performed at the Bevatron. From 1079 events between 0.2 and 7 K_S^0 lifetime, we find ReX=-0.069±0.036, ImX=+0.108_(-0.074)^(+0.092). This result is consistent with X=0 (relative probability = 0.25), but more than 4 standard deviations from the existing world average, +0.14 -0.13i

Action plan co-optimization reveals the parallel encoding of competing reach movements.

Several influential cognitive theories propose that in situations affording more than one possible target of action, we prepare multiple competing movements before selecting one. Here we provide direct evidence for this provocative but largely untested idea and demonstrate why preparing multiple movements is computationally advantageous. Using a reaching task in which movements are initiated after one of two potential targets is cued, we show that the movement generated for the cued target borrows components of the movement that would have been required for the other, competing target. This interaction can only arise if multiple potential movements are fully specified in advance and we demonstrate that it reduces the time required to launch a given action plan. Our findings suggest that this co-optimization of motor plans is highly automatic and largely occurs outside conscious awareness.The study was supported by the Natural Sciences and Engineering Research Council of Canada; the Wellcome Trust; the Human Frontiers Science Program; and the Royal Society.

Method and concept evaluation of relaying oysters from Chesapeake Bay to high salinity water as a post-harvest-process to reduce Vibrio vulnificus to undetectable levels: Final Report

Post-harvest processing (PHP) methods for reducing vibrio levels that have been developed thus far are either capital intensive, have limited throughput, are not readily available, and/or are generally very expensive. In the summer of 2010 we initiated a small-scale evaluation to assess the effectiveness of relay to elevated salinity as a PHP strategy to reduce levels of Vibrio vulnificus in Crassostrea virginica oysters
