Effects of Cheating on Accurate Assessment

In the view of Boud and Falchikov (2006) assessment has the clear purpose of certifying a level of attainment of a student at the point of completion of a course or a program. To produce sufficient number of ethical citizens, advancement of the quality of student performance assessment has been irrefutably recognized. Student performance assessment is a procedure to confirm institutional efficiency. Student assessments are widely accepted as an important part of the learning process. Thus, the primary purpose of this study is to scrutinize the impacts of exam administration and student-paper scoring approaches on accurate performance assessment, taking the case of one of the Universities in Ethiopia and the world in general

The Annelid Community of a Natural Deep-sea Whale Fall off Eastern Australia

In the deep ocean, whale falls (deceased whales that sink to the seafloor) act as a boost of productivity in this otherwise generally food-limited setting, nourishing organisms from sharks to microbes during the various stages of their decomposition. Annelid worms are habitual colonizers of whale falls, with new species regularly reported from these settings and their systematics helping to resolve biogeographic patterns among deep-sea organic fall environments. During a 2017 expedition of the Australian research vessel RV Investigator to sample bathyal to abyssal communities off Australia’s east coast, a natural whale fall was opportunistically trawled at ~1000 m depth. In this study, we provide detailed taxonomic descriptions of the annelids associated with this whale-fall community, using both morphological and molecular techniques. From this material we describe nine new species from five families (Dorvilleidae: Ophryotrocha dahlgreni sp. nov. Ophryotrocha hanneloreae sp. nov., Ophryotrocha ravarae sp. nov.; Hesionidae: Vrijenhoekia timoharai sp. nov.; Nereididae: Neanthes adriangloveri sp. nov., Neanthes visicete sp. nov.; Orbiniidae: Orbiniella jamesi sp. nov.), including two belonging to the bone-eating genus Osedax (Siboglinidae: Osedax waadjum sp. nov., Osedax byronbayensis sp. nov.) that are the first to be described from Australian waters. We further provide systematic accounts for 10 taxa within the Ampharetidae, Amphinomidae, Microphthalmidae, Nereididae, Orbiniidae, Phyllodocidae, Protodrilidae, Sphaerodoridae and Phascolosomatidae. Our investigations uncover unique occurrences and for the first time enable the evaluation of biogeographic links between Australian whale falls and others in the western Pacific as well as worldwide.Marine Biodiversity Hub, supported through the Australian Government's National Environmental Science Program (NESP)UK Research & Innovation (UKRI) Natural Environment Research Council (NERC) NE/R000670/1Ifremer Postdoctoral FellowshipChadwick Biodiversity Fellowship from the Australian MuseumAustralian Biological Resources Study (ABRS) RG18-2

Exploring the agency consequences of ownership dispersion among the directors of private family firms

International audienceUsing an agency-theoretic lens and insights drawn from the behavioral economics and family business literatures, this study developed hypotheses concerning the effect of dispersion of ownership on the use of debt by private family-owned and family-managed firms. A field study of 1,464 family firms was conducted. Results suggest that, during periods of market growth, the relationship between the use of debt and the dispersion of ownership among directors at family firms can be graphed as a U-shaped curve. The nonlinear relationship suggests that family firms are most vulnerable to conflict, and least willing to bear added risk, when ownership is split in relatively equal proportions. Interestingly, the fact that this distribution appeared in only 22% of the sample firms suggests that most family firm owners may take such risk into consideration when making their estate plans<br/

A profile of teen smokers who volunteered to participate in school-based smoking intervention

<p>Abstract</p> <p>Objectives</p> <p>Although a number of population-based studies have examined the characteristics of teens who attempt to quit smoking, few have identified the characteristics of youth who participate in structured cessation interventions, particularly those with demonstrated effectiveness. The purpose of the present study is to describe the sociodemographic and smoking-related characteristics of teen smokers who participated in the American Lung Association's Not On Tobacco (N-O-T) program, spanning eight years. N-O-T is the most widely used teen smoking cessation program in the nation.</p> <p>Methods</p> <p>Drawn from multiple statewide N-O-T studies, this investigation examined data from 5,892 teen smokers ages 14–19 who enrolled in N-O-T between 1998–2006. We demonstrate similarities and differences between N-O-T findings and existing data from representative samples of US teen smokers where available and relevant.</p> <p>Results</p> <p>N-O-T teens started smoking earlier, were more likely to be poly-tobacco users, were more dependent on nicotine, had made more previous attempts to quit, and were more deeply embedded in smoking contexts than comparative samples of teen smokers. Additionally, N-O-T teens were moderately ready to quit smoking, believed important people in their lives would support their quit efforts, yet had deficits in their confidence with quitting.</p> <p>Conclusion</p> <p>This profile of N-O-T teens can guide efforts for targeted recruitment strategies to enhance intervention reach for teen smoking cessation. Findings provide guidance for marketing and recruitment efforts of intensive, school-based cessation interventions among established teen smokers, particularly those who want to quit. Study results may shed light upon who is and is not enrolling in N-O-T.</p
