The risky investment game of Gneezy and Potters :631–645, 1997) has been proposed as a simple tool to measure risk aversion in applied settings, especially attractive in settings where participants may have limited education. However, this game can produce a significant endowment effect, so that analysis of the behavior in this game should not be done in the Expected Utility Theory framework. The paper illustrates this point, by showing that risk tolerance can be much higher when the initial endowment concerns (...) a risky lottery. (shrink)

Medical students lack opportunities to have authentic conversations with patients with cancer in busy hospitals. An improved understanding of what such communication might look like may provide a framework for end-of-life curricula. The authors performed thematic analysis using written correspondence between patient and student participants in the University of California, San Francisco’s Firefly Program whose letters discussed death or dying. Four themes emerged: (1) turmoil, (2) grief, (3) making peace, and (4) past, present, and future. Medical students expressed a fifth (...) theme: unmet student expectations. The study provides educators with a unique perspective to help inform curriculum development and patient care. (shrink)

Biocentrism environmental ethicists and animal rights defenders have been articulating ethical principles to extend moral standing to nonhuman beings. The natural propensities of living beings to pain and pleasure, being a subject of life, and having specific good and interest (as proposed by Singer, Regan, Tayler, and Goodpaster, respectively), have been taken as a reason to determine the moral status of the beings in question. This article makes the case that none of them can offer all-inclusive ideal for biocentrism to (...) embrace all life forms as moral patients since they are either exclusive, hierarchical, or imprecise. To this end, I argue that it is possible to drive a unifying ideal from Schopenhauer’s metaphysics: the will to live. The will to live is a quality that all living beings share, regardless of their abilities and propensities. Both conscious and unconscious beings, sentient and non-sentient creatures, lower animals and plants are the embodi­ments or physical forms of the ultimate reality that is the will to live. Thus, biocentrism becomes more valid and effective in environmental preservation by incorporating the will to live into its ethical principle. (shrink)

Meat abstinence, as is practiced in some religions, has a positive impact on reducing the damages that the process of meat production inflicts on the environment. The Ethiopian Orthodox Christians observe fasting by abstaining from meat for more than half a year, and this seems to do the environment and economy some good. Religion has been playing a regulatory role between ever-increasing meat demands and the country’s fast-growing meat and live animal exports. The article concludes that individuals' tendency to drift (...) from religious life practices, coupled with a growing middle class that can afford to buy meat regularly, and the country’s need to maximize foreign currency through meat and livestock exportation, is likely to see Ethiopia introduce intensive livestock production in the not too distant future, to meet domestic meat demands and increase livestock export earnings.

IntroductionInternet addiction is characterized by excessive and uncontrolled use of the internet affecting everyday life. Adolescents are the primary risk group for internet addiction. Data on internet addiction is lacking in Africa. Thus, this review aimed to determine the pooled prevalence of internet addiction and its associated factors among high school and university students in Africa.MethodsA comprehensive literature search was conducted using electronic databases to locate potential studies. Heterogeneity between studies was checked using Cochrane Q test statistics and I2 test (...) statistics and small-study effects were checked using Egger's statistical test at a 5% significance level. A sensitivity analysis was performed. A random-effects model was employed to estimate the pooled prevalence and associated factors of internet addiction among students. The primary outcome of measure of this review was the prevalence of internet addiction and the secondary outcome of measures are the factors associated with internet addiction.ResultsA total of 5,562 studies were identified among the five databases. Of these, 28 studies from 10 countries with 14,946 high school and university students were included in this review. The overall pooled prevalence of internet addiction among the students was 34.53% [95% Confidence Interval : 26.83, 42.23, I2 = 99.20%]. Male sex [Pooled Odds Ratio = 1.92, 95% CI:1.43, 2.57 I2 = 0.00], urban residence, and duration of daily internet use for more than 4 h (POR = 2.25, 95% CI:1.20, 4.21, I2 = 0.00%, were significantly associated with internet addiction among adolescents.ConclusionAlmost one-third of university and high school students in Africa are addicted to the internet. Male students, those from urban areas, and those who use the internet for more than 4 h per day have higher odds of internet addiction. Thus, we recommend that health planners and policymakers pay attention to the use of the internet and internet addiction in Africa. (shrink)

The complex hexaploid wheat genome offers many challenges for genomics research. Expressed sequence tags facilitate the analysis of gene-coding regions and provide a rich source of molecular markers for mapping and comparison with model organisms. The objectives of this study were to construct a high-density EST chromosome bin map of wheat homoeologous group 2 chromosomes to determine the distribution of ESTs, construct a consensus map of group 2 ESTs, investigate synteny, examine patterns of duplication, and assess the colinearity with rice (...) of ESTs assigned to the group 2 consensus bin map. A total of 2600 loci generated from 1110 ESTs were mapped to group 2 chromosomes by Southern hybridization onto wheat aneuploid chromosome and deletion stocks. A consensus map was constructed of 552 ESTs mapping to more than one group 2 chromosome. Regions of high gene density in distal bins and low gene density in proximal bins were found. Two interstitial gene-rich islands flanked by relatively gene-poor regions on both the short and long arms and having good synteny with rice were discovered. The map locations of two ESTs indicated the possible presence of a small pericentric inversion on chromosome 2B. Wheat chromosome group 2 was shown to share syntenous blocks with rice chromosomes 4 and 7. (shrink)
