A cross-country evaluation of cheating in academia: is it related to ‘real world’ business ethics?

Today’s economics and business students are expected to be our future’s business people and potentially our tomorrow’s economic leaders and politicians. Thus, their beliefs and practices are likely to affect the definition of acceptable economics and business ethics. The empirical evaluation of the cheating phenomenon in academia has been almost exclusively focused on the US context, and the non-US studies involve, in general, a narrow scope of countries. In the present paper we perform a wide cross-country study on the determinants of economics and business undergraduate cheating which involves 21 countries from the American (4), European (14), Africa (2) and Oceania (1) Continents and 7213 students. We found that the average magnitude of copying among the economics and business undergraduates is quite high (62%) but with a significant cross-country heterogeneity. The probability of cheating is significantly lower in students enrolled in schools located in the Nordic or the US plus British Isles blocks when compared with their South Europe counterparts; quite surprisingly that probability is also lower for the African block. Distinctly, students enrolled in schools from the Western and especially from the Eastern Europe observe statistically significant higher propensities for perpetrating academic fraud. Our findings further suggest that average cheating propensity in academia is significantly correlated with ‘real world’ business corruption.cheating; corruption; university; economics; business; countries

Frequency characteristics of aerial scenes with respect to a video imagining system

Thesis (M.A.)--Boston UniversityAn overall investigation is made of operating characteristics, theoretical limitations and optimum range values for video communication of aerial scenes. Reasons are given for the selection of a particular receiver and the importance of this type of study is indicated from the A.D.P. crystals' complex A.C. frequency response. The restricted contrast range, due to haze, is noted in evaluating the various video systems

Changes in salivary estradiol predict changes in women’s preferences for vocal masculinity

Although many studies have reported that women’s preferences for masculine physical characteristics in men change systematically during the menstrual cycle, the hormonal mechanisms underpinning these changes are currently poorly understood. Previous studies investigating the relationships between measured hormone levels and women’s masculinity preferences tested only judgments of men’s facial attractiveness. Results of these studies suggested that preferences for masculine characteristics in men’s faces were related to either women’s estradiol or testosterone levels. To investigate the hormonal correlates of within-woman variation in masculinity preferences further, here we measured 62 women’s salivary estradiol, progesterone, and testosterone levels and their preferences for masculine characteristics in men’s voices in five weekly test sessions. Multilevel modeling of these data showed that changes in salivary estradiol were the best predictor of changes in women’s preferences for vocal masculinity. These results complement other recent research implicating estradiol in women’s mate preferences, attention to courtship signals, sexual motivation, and sexual strategies, and are the first to link women’s voice preferences directly to measured hormone levels

The effect of natural and anthropogenic nutrient and sediment loads on coral oxidative stress on runoff-exposed reefs

Recently, corals on the Great Barrier (GBR) have suffered mass bleaching. The link between ocean warming and coral bleaching is understood to be due to temperature-dependence of complex physiological processes in the coral host and algal symbiont. Here we use a coupled catchment-hydrodynamic-biogeochemical model, with detailed zooxanthellae photophysiology including photoadaptation, photoacclimation and reactive oxygen build-up, to investigate whether natural and anthropogenic catchment loads impact on coral bleaching on the GBR. For the wet season of 2017, simulations show the cross-shelf water quality gradient, driven by both natural and anthropogenic loads, generated a contrasting zooxanthellae physiological state on inshore versus mid-shelf reefs. The relatively small catchment flows and loads delivered during 2017, however, generated small river plumes with limited impact on water quality. Simulations show the removal of the anthropogenic fraction of the catchment loads delivered in 2017 would have had a negligible impact on bleaching rates

Towards Sustainable Co-Management of Mekong River Inland Aquatic Resources, Including Fisheries, in Southern Lao PDR

This paper presents historical information regarding the development of the aquatic resource co-management system in Khong District, Champasak Province, Southern Lao PDF. Between 1993 and 1998, 63 villages in Khong District established co-management regulations to sustainably manage and conserve inland aquatic resources, including fisheries, in the Mekong River, streams, backwater wetlands, and rice paddy fields. Local government has endorsed these regulations, but villages have been given the mandate to choose what regulations to adopt based on local conditions and community consensus. Communities are also empowered to alter regulations in response to changing circumstances. Villagers have widely reported increased fish catches since the adoption of aquatic resource co-management regulations. Improved solidarity and coordination within and between rural fishing and farming villages has also been observed. While many of the lessons learned from the co-management experience in Khong are applicable to other parts of Laos and the region, unique conditions in different areas will require inventive approaches to meet local needs. Common property regimes can break down in crisis, but experience in Khong indicates that they can also be strengthened in response to resource management crisis

Ion torrent-based transcriptional assessment of a Corynebacterium pseudotuberculosis equi strain reveals denaturing high-performance liquid chromatography a promising rRNA depletion method

Corynebacterium pseudotuberculosis equi is a Gram-positive pathogenic bacterium which affects a variety of hosts. Besides the great economic losses it causes to horse-breeders, this organism is also known to be an important infectious agent to cattle and buffaloes. As an outcome of the efforts in characterizing the molecular basis of its virulence, several complete genome sequences were made available in recent years, enabling the large-scale assessment of genes throughout distinct isolates. Meanwhile, the RNA-seq stood out as the technology of choice for comprehensive transcriptome studies, which may bring valuable information regarding active genomic regions, despite of the still impeditive associated costs. In an attempt to increase the use of generated reads per instrument run, by effectively eliminating unwanted rRNAs from total RNA samples without relying on any commercially available kits, we applied denaturing high-performance liquid chromatography (DHPLC) as an alternative method to assess the transcriptional profile of C. pseudotuberculosis. We have found that the DHPLC depletion method, allied to Ion Torrent sequencing, allows mapping of transcripts in a comprehensive way and identifying novel transcripts when a de novo approach is used. These data encourage us to use DHPLC in future transcriptional evaluations in C. pseudotuberculosis
