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 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)

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.

The literature on Base of the Pyramid strategies emphasizes that creating social value requires collaborative, multi-stakeholder business approaches. However, there is limited understanding of how businesses can successfully coordinate such value creation processes in the developing economies that face significant institutional voids. This study adopts a business model perspective for analyzing social value creation processes that span organizational boundaries. We introduce a novel, theoretically grounded business model framework that helps conceptualize social value by locating the various loci of value creation, (...) and the stakeholders that partake in creating and capturing this value. We subsequently analyze the mechanisms of social value creation in M-Pesa, a renowned boundary-spanning mobile money system that has advanced financial inclusion among tens of millions of users in Kenya. The results show that information and communications technology can help advance social value creation by reducing the cost of coordinating boundary-spanning business models that integrate diverse societal stakeholders. The results further point to uneven distributional outcomes in self-governing social value creation strategies where the focal firm plays a coordinating role. (shrink)

Despite devoting their time to another person’s needs, many carers paradoxically experience guilt during their caregiving tenure concerning whether they are providing enough care. When discussing the “enough” of anything, what is at stake is that thing’s quantification. Given that there are seemingly no quantifiable units of care by which to measure the role, concerns regarding whether enough care is being provided often focus on what constitutes enough time as a carer. In exploring this aspect of the carer’s experience, two (...) key parameters emerge; guilt, and, quantified time. The guilt that carers report regarding whether they devote “enough time” to their caring responsibilities can be examined through Henri Bergson’s philosophical conception of quantification. By integrating contemporary analyses of carers’ guilt from the social sciences, most significantly via the sociology of Rebecca Olson, the relationship between quantified time and guilt becomes apparent. A quantified conception of time frames the assumption that spending more time on caregiving will reduce the amount of guilt felt by a carer. However, whilst care is structured according to quantified, clocked and calendared time, there are not comparable, quantifiable parameters for guilt. This means that suppositions of an inverse relationship between how much time one spends giving care, and how much guilt they will feel in terms of their caregiving, are problematic. These insights become relevant to health care policies via a coherence with calls to make the role of unpaid, caregiving, labour time more visible, and by explaining how understanding quantified time can help policies guide how caregivers negotiate guilt.

It is widely assumed that we can meaningfully talk about emotional reactions as being appropriate or inappropriate. Much of the discussion has focused on one kind of appropriateness, that of fittingness. An emotional response is appropriate only if it fits its object. For instance, fear only fits dangerous things. There is another dimension of appropriateness that has been relatively ignored — proportionality. For an emotional reaction to be appropriate not only must the object fit, the reaction should be of the (...) appropriate intensity. It should be proportional. The problem for any attempt to develop norms of appropriateness is that proportionality is a factor of how much the person cares about the focus. But, as I argue, it is not clear how we should normatively assess care. I present problems for a few ways to assess the normativity of care and argue that the difficulties are compounded when it comes to fiction. (shrink)

This chapter focuses on one of the common fallacies in Western philosophy called 'proving too much'. The proving too much fallacy has been committed when an argument can be used to also prove something false or leads to contradictory conclusions. An argument that proves too much demonstrates a lack of soundness, since sound arguments can only establish true conclusions, and thus when an argument can be used to prove false conclusions, it becomes evident that there is a flaw in its (...) reasoning. The fallacy of proving too much is not really a single fallacy so much as a great tool for detecting faulty reasoning, since any argument that leads to a contradiction cannot be sound. There are a few forms this fallacy can take on such as when an argument leads to multiple contradictory conclusions. (shrink)

Joshua Parker has made many interesting points, and we welcome the opportunity to develop the ideas of ‘Too Much Medicine, Not Enough Trust’. We will address: (i) the asymmetry between the trust that patients extend to doctors, and the trust that doctors extend to patients; (ii) our reasons for doubting that litigation or complaints reflect a betrayal of the patient–doctor relationship and (iii) the importance of institutional trust, both for the doctor and the patient.

How much information from experience does a normal adult remember? The “functional information content” of human memory was estimated in several ways. The methods depend on measured rates of input and loss from very long‐ term memory and on analyses of the informational demands of human memory‐based performance. Estimates ranged around 109 bits. It is speculated that the flexible and creative retrieval of facts by humans is a function of a large ratio of “hardware” capacity to functional storage requirements.

This essay investigates the origins and assesses the advantages and disadvantages of the new field known as Wissensgeschichte from the perspective of an American intellectual historian. It argues that while some historians of science may be ready to embrace a new identity as historians of knowledge, this terminology remains baggy and invites facile applications of Foucauldian theory. The essay concludes with the hope that the history of knowledge approach may instead open up new avenues for conversation and collaboration between historians (...) of science and garden variety historians.

Longtermists have argued that humanity should significantly increase its efforts to prevent catastrophes like nuclear wars, pandemics, and AI disasters. But one prominent longtermist argument overshoots this conclusion: the argument also implies that humanity should reduce the risk of existential catastrophe even at extreme cost to the present generation. This overshoot means that democratic governments cannot use the longtermist argument to guide their catastrophe policy. In this paper, we show that the case for preventing catastrophe does not depend on longtermism. (...) Standard cost-benefit analysis implies that governments should spend much more on reducing catastrophic risk. We argue that a government catastrophe policy guided by cost-benefit analysis should be the goal of longtermists in the political sphere. This policy would be democratically acceptable, and it would reduce existential risk by almost as much as a strong longtermist policy. (shrink)

Mr. Bork discusses concern over press power and irresponsibility, particularly the attitude of the press that the public's "right to know" gives them the right to publish anything. He expresses concern that the public backlash could lead to excessive restrictions on the press.

The latest round of cuts will be painful. There is little fat left. But there are some areas where we are, although lean, extravagant. We are extravagant in our provision of lectures and our use of tutorials. Although we are justly proud of our teaching, it is worth looking at our practices to see whether we could not be more economical in our use of resources without damaging our achievement.

Abstract:In this paper I begin to theorize what secondary school music education might look like “post-deconstruction.” In particular, I explore the argument for a reconsideration of the importance of conceptualization in the process of music education. I argue that is it through coming into contact with powerful conceptual knowledge that students’ potential to participate fully as capable musicians in their world is most likely to be realized. Conceptual knowledge provides the link between experience and the understanding of that experience. The (...) great paradox of postmodernism is that in opening up some possibilities we have subsequently closed others down. There is a danger that in placing the knower rather than knowledge at the center of our educational endeavors, we have reduced access to something extremely important: the dimensions of knowledge that hold the power for students to move beyond their experiences, to imagine, and conceptualize a different world.

Mike Otsukaʼs book aspires to do more than its title discloses. Libertarianism without Inequality (Oxford University Press, 2003) does not merely aim to reconcile liberty and equality (that is handled without remainder in the first chapter) but to draw the outlines of a complete, and distinctly Lockean, political theory. Rather than starting from first principles, Otsuka explores several specific issues only loosely connected to each other, hoping that these might add up to a complete political vision. Though the discussion is (...) clearly tinted in Lockean colours, his conclusions are always provocative and difficult to swallow, even for modern disciples of Locke. Thus he argues for the following theses. (shrink)

In his Laozi Commentary and Structure of the Laozi’s Subtle Pointers, Wang Bi 王弼 seems to identify the Dao 道 with “absence” or “nothingness”. Despite this identification, some modern commentators regard Wang Bi’s Dao as a being. Other commentators deny that the Dao is a being but, nonetheless, seem to regard it as a reality of some kind. In contrast, I propose that Wang Bi’s Dao is literal absence and that we need not reify this absence in any way. Wang (...) Bi’s descriptions of the Dao can be understood as metaphorical descriptions of mere absence. To support this proposal, I present an interpretation of Wang Bi’s Dao and then apply this interpretation to the first section of Wang Bi’s Laozi Commentary and to the first section of the Structure of the Laozi’s Subtle Pointers.

English distinguishes between singular quantifiers like "a donkey" and plural quantifiers like "some donkeys". Pluralists hold that plural quantifiers range in an unusual, irreducibly plural, way over common objects, namely individuals from first-order domains and not over set-like objects. The favoured framework of pluralism is plural first-order logic, PFO, an interpreted first-order language that is capable of expressing plural quantification. Pluralists argue for their position by claiming that the standard formal theory based on PFO is both ontologically neutral and really (...) logic. These properties are supposed to yield many important applications concerning second-order logic and set theory that alternative theories supposedly cannot deliver. I will show that there are serious reasons for rejecting at least the claim of ontological innocence. Doubt about innocence arises on account of the fact that, when properly spelled out, the PFO-semantics for plural quantifiers is committed to set-like objects. The correctness of my worries presupposes the principle that for every plurality there is a coextensive set. Pluralists might reply that this principle leads straight to paradox. However, as I will argue, the true culprit of the paradox is the assumption that every definite condition determines a plurality. (shrink)
