UNDERSTANDING THE EFFECT OF DETERRENCE MECHANISMS ON CYBERLOAFING: EXPLORING A GENERAL DETERRENCE MODEL WITH A SOCIAL PERSPECTIVE

As the use of the Internet has grown, so have new ways for employees to loaf. Cyberloafing has become a pervasive problem for firms. Information systems researchers have suggested that a deterrence approach through the use of acceptable use policies for Internet-based applications coupled with Internet monitoring mechanisms can be an effective way to reduce cyberloafing without actively blocking websites and impeding on the positive aspects of the Internet. However, the effectiveness of the deterrence approach is still in question due to inconsistent results in existing research. This study aims to reconcile these inconsistencies by exploring how other factors interact with the deterrence model. We propose that the deterrence model will affect more deviant types of behaviors differently than those that are perceived to be more socially acceptable. We also suggest that employees will self-impose expected ramifications or sanctions on themselves when they expect to get caught cyberloafing

Exploring the Importance of Mentoring for New Scholars: A Social Exchange Perspective

This exploratory study examines the importance of mentor/mentee relationships on faculty development by measuring how social exchange between new faculty members (mentees) in information systems and their former dissertation chairs (mentors) relate to how quickly the new faculty members completed their doctoral program and the number of peer reviewed publications they produced in their first six years of academic employment. In addition, this study measures how gender and ethnicity relate to the strength of the social exchange between mentors and mentees. The results show a statistically significant relationship between social ties and the number of publications new faculty obtain in their early years of academic employment. The results also indicate that mixed gender pairs have higher social exchange in this context. This study has implications for shaping doctoral education by providing insight into the importance of social ties on the development and productivity of new faculty

Cyber-Slacking: Self-Control, Prior Behavior And The Impact Of Deterrence Measures

To further our understanding about how to control Internet abuse in the workplace, this study examines how a person’s level of self-control leads to cyber-slacking, how deterrence measures commonly used within organizations impact individual decisions to cyber-slack, and how self-control moderates the relative salience of one of the commonly used deterrence mechanisms against cyber-slacking, detection (monitoring) systems.  The results suggest that individuals that rate low in self-control overlook potential consequences for abusing the Internet in favor of immediate rewards, thus they have difficulty self-regulating themselves and have a higher propensity to cyber-slack.  The results also indicate that detection systems and awareness of the enforcement of sanctions are the biggest deterrents on individual intentions to cyber-slack and detection systems are even more salient to individuals that rate low in self-control.

An Empirically Based Calculation of the Extragalactic Infrared Background

Using the excellent observed correlations among various infrared wavebands with 12 and 60 micron luminosities, we calculate the 2-300 micron spectra of galaxies as a function of luminosity. We then use 12 micron and 60 micron galaxy luminosity functions derived from IRAS data, together with recent data on the redshift evolution of galaxy emissivity, to derive a new, empirically based IR background spectrum from stellar and dust emission in galaxies. Our best estimate for the IR background is of order 2-3 nW/m^2/sr with a peak around 200 microns reaching 6-8 nW/m^2/sr. Our empirically derived background spectrum is fairly flat in the mid-IR, as opposed to spectra based on modeling with discrete temperatures which exhibit a "valley" in the mid-IR. We also derive a conservative lower limit to the IR background which is more than a factor of 2 lower than our derived flux.Comment: 14 pages AASTeX, 2 .ps figures, the Astrophysical Journal, in pres

Exploring The Effects Of Social Exchange Relationships On The Scholarly Productivity Of New Faculty Members In Accounting

This paper explores how social relationships between new accounting faculty members and their former dissertation chairs can influence the publishing productivity of the new faculty members in their early academic careers. The focus on social relationships offers a unique approach to studying the effectiveness doctoral education. Our findings show that strong social exchange between new faculty members and their former chairs can have a significant impact on new faculty members’ scholarly productivity and provide some reasons for those effects. We also find differences in relationships between mixed and same gender pairs and examine reasons for those differences

Chromatin profiling of Drosophila CNS subpopulations identifies active transcriptional enhancers

One of the key issues in studying transcriptional regulation during development is how to employ genome-wide assays that reveals sites of open chromatin and transcription factor binding to efficiently identify biologically relevant genes and enhancers. Analysis of Drosophila CNS midline cell development provides a useful system for studying transcriptional regulation at the genomic level due to a large, well-characterized set of midline-expressed genes and in vivo validated enhancers. In this study, FAIRE-seq on FACS-purified midline cells was performed and the midline FAIRE data were compared with whole-embryo FAIRE data. We find that regions of the genome with a strong midline FAIRE peak and weak whole-embryo FAIRE peak overlap with known midline enhancers and provide a useful predictive tool for enhancer identification. In a complementary analysis, we compared a large dataset of fragments that drive midline expression in vivo with the FAIRE data. Midline enhancer fragments with a midline FAIRE peak tend to be near midline-expressed genes, whereas midline enhancers without a midline FAIRE peak were often distant from midline-expressed genes and unlikely to drive midline transcription in vivo

Twine: display and analysis of cis-regulatory modules

Summary: Many algorithms analyze enhancers for overrepresentation of known and novel motifs, with the goal of identifying binding sites for direct regulators of gene expression. Twine is a Java GUI with multiple graphical representations (‘Views’) of enhancer alignments that displays motifs, as IUPAC consensus sequences or position frequency matrices, in the context of phylogenetic conservation to facilitate cis-regulatory element discovery. Thresholds of phylogenetic conservation and motif stringency can be altered dynamically to facilitate detailed analysis of enhancer architecture. Views can be exported to vector graphics programs to generate high-quality figures for publication. Twine can be extended via Java plugins to manipulate alignments and analyze sequences

Drosophila melanogaster Zelda and Single-minded collaborate to regulate an evolutionarily dynamic CNS midline cell enhancer

The Drosophila Zelda transcription factor plays an important role in regulating transcription at the embryonic maternal-to-zygotic transition. However, expression of zelda continues throughout embryogenesis in cells including the developing CNS and trachea, but little is known about its post-blastoderm functions. In this paper, it is shown that zelda directly controls CNS midline and tracheal expression of the link (CG13333) gene, as well as link blastoderm expression. The link gene contains a 5’ enhancer with multiple Zelda TAGteam binding sites that in vivo mutational studies show are required for link transcription. The link enhancer also has a binding site for the Single-minded: Tango and Trachealess:Tango bHLH-PAS proteins that also influences link midline and tracheal expression. These results provide an example of how a transcription factor (Single-minded or Trachealess) can interact with distinct co-regulatory proteins (Zelda or Sox/POU-homeodomain proteins) to control a similar pattern of expression of different target genes in a mechanistically different manner. While zelda and single-minded midline expression is well-conserved in Drosophila, midline expression of link is not well-conserved. Phylogenetic analysis of link expression suggests that ~60 million years ago, midline expression was nearly or completely absent, and first appeared in the melanogaster group (including D. melanogaster, D. yakuba, and D. erecta) >13 million years ago. The differences in expression are due, in part, to sequence polymorphisms in the link enhancer and likely due to altered binding of multiple transcription factors. Less than 6 million years ago, a second change occurred that resulted in high levels of expression in D. melanogaster. This change may be due to alterations in a putative Zelda binding site. Within the CNS, the zelda gene is alternatively spliced beginning at mid-embryogenesis into transcripts that encode a Zelda isoform missing three zinc fingers from the DNA binding domain. This may result in a protein with altered, possibly non-functional, DNA-binding properties. In summary, Zelda collaborates with bHLH-PAS proteins to directly regulate midline and tracheal expression of an evolutionary dynamic enhancer in the post-blastoderm embryo

Susceptibility of Selected Potato Varieties to Zebra Chip Potato Disease

Zebra chip (ZC), an emerging and serious disease of potato has caused millions of dollars in losses to the potato industry in the United States, Mexico, Central America, and New Zealand. The disease has recently been associated with a previously undescribed species of liberibacter tentatively named “Candidatus Liberibacter solanacearum” transmitted to potato by the potato psyllid, Bactericera cockerelli (Šulc). At present, applications of insecticides targeted against the potato psyllid are the only means to manage ZC. Given the low psyllid density and short inoculation access period required to induce the disease, insecticides may not act fast enough to prevent transmission of liberibacter to potato by the psyllid and development of ZC. Identification and development of ZC-resistant or tolerant varieties may offer the most efficient and sustainable way to manage this potato disease. Susceptibility of selected potato varieties to ZC was evaluated under controlled field cage conditions in 2009 and 2010 in WA by inoculating potato plants with “Ca. L. solanacearum” using infective potato psyllids and monitoring them for ZC symptom development. All potato varieties evaluated in both years of the study were determined to be very susceptible to the disease, with almost 100% of the inoculated plants developing severe ZC foliar and tuber symptoms. Potato yield in all tested varieties was significantly affected by ZC, with yield losses ranging from 49.9% to 87. 2%. Information from this research suggests that there is an urgent need to develop new potato varieties that are resistant or tolerant to this damaging potato disease

BREATHLEssness in INDIA (BREATHE-INDIA)–Study protocol for the co-design of a community breathlessness intervention in India using realist methods and intervention mapping

Background Breathlessness that persists despite treatment of causal disease(s) is disabling, associated with high therapy-related costs and poor socioeconomic outcomes. Low resource countries bear a disproportionate burden of respiratory problems, often characterised by disabling breathlessness. Low-cost self-management breathlessness-targeted interventions are effective and deliverable in community settings but have been developed in high-income countries. We aim to understand how breathlessness self-management works in ‘real life’ populations and cultural contexts, to develop programme theory and co-design a prototype intervention to improve persistent breathlessness management in India. Methods and analysis Using a Realist approach, Intervention Mapping and the Medical Research Council Complex Intervention Framework we will undertake two phases of work supported by our Expert Group (of respiratory, primary, palliative care physicians) and key stakeholder groups (opinion leader clinicians, community health workers and people with lived experiences of breathlessness). 1) Realist review and evaluation to identify and refine evidence and theory for breathlessness self-management, producing intervention and implementation programme theory. We will identify literature through our Expert Group, scoping searches and systematic searches (Medline, Ebscohost, CINAHL, Scopus, Psychinfo). We will map intervention components to ‘what works, for whom, and where.’ 2) Intervention development using Intervention Mapping to map intervention and implementation programme theory to intervention components, develop materials to support intervention delivery, and co-design a prototype educational intervention ready for early acceptability and delivery-feasibility testing and evaluation planning in India. Use of stakeholder groups is to allow people with experience of breathlessness and/or its management to contribute their views on content developed by our team based upon review of secondary data sources. Experts and Stakeholders are therefore not research subjects but are included as extended members of the study team and will not follow informed consent procedures. Experts and stakeholders will be acknowledge in outputs arising from our project if they wish to be. Our review conduct will be consistent with RAMESES quality standards. Discussion At the conclusion of our study, we will have co-designed a breathlessness intervention for use in the community setting in India ready for further evaluation of: effectiveness, socioeconomic outcomes, acceptability and transferability to other low resource settings
