Contemporary Music and Dance in Nigeria: Morality Question

Music and Dance are two inseparable duo that have co-existently been entangled in a web of symbiotic relationship over the years.  Towing a comparative path, Music and Dance, in view of their inter-relationship are appraised to ascertain certain levels of conformity in their semiotic modes – both as medium of communication and psychological influence.  However, the idea of utilitarianism suggests that the value of a thing depends on its use and not its beauty. It is in this vein that contemporary Nigerian music and dance have failed in their purpose of communication and influence especially as it affects the morality question.  In recent times, the flock of the 21st Century contemporary Music and Dance have been characterized by such high vulgarity in language (lyrics) and dance patterns that has resulted to such permeability of moral decadence and sexualities among Nigerian youths and children; an impending menace which the core of this paper seeks to address by critically examining and analyzing some selected contemporary Nigerian Music and Dance in this respect, towards a good future for Nigerian audience. Key words: Music, dance, morality, nudity, sex

Low temperatures impact species distributions of jumping spiders across a desert elevational cline.

Temperature is known to influence many aspects of organisms and is frequently linked to geographical species distributions. Despite the importance of a broad understanding of an animal's thermal biology, few studies incorporate more than one metric of thermal biology. Here we examined an elevational assemblage of Habronattus jumping spiders to measure different aspects of their thermal biology including thermal limits (CTmin, CTmax), thermal preference, V̇CO2 as proxy for metabolic rate, locomotor behavior and warming tolerance. We used these data to test whether thermal biology helped explain how species were distributed across elevation. Habronattus had high CTmax values, which did not differ among species across the elevational gradient. The highest-elevation species had a lower CTmin than any other species. All species had a strong thermal preference around 37 °C. With respect to performance, one of the middle elevation species was significantly less temperature-sensitive in metabolic rate. Differences between species with respect to locomotion (jump distance) were likely driven by differences in mass, with no differences in thermal performance across elevation. We suggest that Habronattus distributions follow Brett's rule, a rule that predicts more geographical variation in cold tolerance than heat. Additionally, we suggest that physiological tolerances interact with biotic factors, particularly those related to courtship and mate choice to influence species distributions. Habronattus also had very high warming tolerance values (> 20 °C, on average). Taken together, these data suggest that Habronattus are resilient in the face of climate-change related shifts in temperature

Skin tear prevalence in an Australian acute care hospital : A 10-year analysis

Hospital-acquired skin tear prevalence is under-reported; thus, the aim of this study was to analyse skin tear point prevalence and characteristics in a tertiary acute care hospital in Queensland, Australia, over a 10-year period. All consenting adult inpatients received a full skin inspection and skin tear category, site, cause, treatment, and whether it was documented as hospital- or community-acquired were recorded. Eleven prevalence audits were analysed with a total sample of 3626 patients. An overall pooled prevalence of 8.9% (95% confidence interval [CI] 7.5-10.4) with an associated hospital-acquired pooled prevalence of 5.5% (95% CI 4.5-6.7) was found. In total, 616 skin tears were reported, of which 374 (60.7%) were hospital-acquired. Over a third of patients (38.7%) had multiple skin tears and most patients (84.8%) with at least one skin tear were aged ≥70 years. The largest proportion of skin tears (40.1%) was those with no skin flap. Of those documented, most were caused by falls or collisions, suggesting combined skin tear and falls prevention strategies may be effective. Over a decade, there was a downward trend in hospital-acquired skin tear, which is encouraging. Skin tear prevalence is recommended as a measure of care quality with an emphasis on good quality documentation

Intersections between Neorealism, Neoliberalism, and Constructivism in IR Theory

Albert and Cederman couch the neorealist perspective in terms of ‘systems’ theorizing, Ferguson and Mansbach rhetorically discuss issues and non-issues which are readily addressed within the neoliberal perspective, and of course, Onuf is unabashedly a constructivist. Below, I discuss each theoretical perspective relative to the articles assigned, and, thereafter conclude with some observations on the three articles and theoretical frameworks

EQUIANO’S MODERNITY: The Context in which Freedom from Slavery was Achieved

For the purposes of this enquiry—an account of what Equiano’sa modernity was, and which particular historical ‘demarcations’ of modernity provided for an enslaved man to achieve freedom through great fortune and great cunning, I will assume a definition of ‘modernity’ as defined by Kathleen Wilson: “. . . not one moment or age, but a set of relations that are constantly being made and unmade, contested and reconfigured, that nonetheless produce among their contemporaneous witnesses the conviction of historical difference.” By adopting this definition, modernity in the times of Equiano refers to, “the cultural practices and representations that produced certain kinds of subjects and objects of knowledge, upheld widely-shared notions of space and time, or facilitated the formation of cultural identities that resulted in pluralities and contradictions as well as unities and coherences,” which provided for a slave to acquire freedom amidst eighteenth-century imperialism, slave-trade, and emerging abolitionist sentiments within bourgeois culture

A Simple, Highly Efficient Method for Heterologous Expression in Mammalian Primary Neurons Using Cationic Lipid-mediated mRNA Transfection

Expression of heterologous proteins in adult mammalian neurons is a valuable technique for the study of neuronal function. The post-mitotic nature of mature neurons prevents effective DNA transfection using simple, cationic lipid-based methods. Adequate heterologous protein expression is often only achievable using complex techniques that, in many cases, are associated with substantial toxicity. Here, a simple method for high efficiency transfection of mammalian primary neurons using in vitro transcribed mRNA and the cationic lipid transfection reagent Lipofectamine™ 2000 is described. Optimal transfection conditions were established in adult mouse dissociated dorsal root ganglion (DRG) neurons using a 96-well based luciferase activity assay. Using these conditions, a transfection efficiency of 25% was achieved in DRG neurons transfected with EGFP mRNA. High transfection efficiencies were also obtained in dissociated rat superior cervical ganglion (SCG) neurons and mouse cortical and hippocampal cultures. Endogenous Ca2+ currents in EGFP mRNA-transfected SCG neurons were not significantly different from untransfected neurons, which suggested that this technique is well suited for heterologous expression in patch clamp recording experiments. Functional expression of a cannabinoid receptor (CB1R), a G protein inwardly rectifying K+ channel (GIRK4) and a dominant-negative G protein α-subunit mutant (GoA G203T) indicate that the levels of heterologous protein expression attainable using mRNA transfection are suitable for most functional protein studies. This study demonstrates that mRNA transfection is a straightforward and effective method for heterologous expression in neurons and is likely to have many applications in neuroscience research

Do Ambiguities in International Humanitarian Law make Cyberattacks more Advantageous?

Does it seem that with each reported state cyberattack, there comes an announcement of discovery, an attribution to one of a handful of usual suspects, some threatening language suggesting imminent retribution, and then nothing more? Increased incidence of cyberattack makes its occurrence seem simultaneously rampant in terms of publicity and minimal in terms of threat of war. If rampant, how can repeated deployment by the same actors carry no punitive consequences? How is such audaciousness tolerated? For some, a cyberattack by a state is an act of war. Its prevalence suggests there must be a void somewhere that facilitates its use without consequence. Others think state cyberattack is like other internet novelties: digital malfeasance, amounting to a nuisance that naturally follows from a digital‐based existence, particularly since non‐state actors are typically involved. Yet, state‐on‐state hostilities are historically perilous on a vast scale, and there is a multilateral system for regulating the use of force in the context of war. Acts of war, even when seeming minimal in impact, are not by‐products of a digital fad, and cyberattack is now described as far more than ‘nuisance’. If anywhere, the place for clarity on hostile state cyberoperations use should be accounted for in International Humanitarian Law. Yet, in its present form, it is ambiguous if not silent on the subject, suggesting that cyberattack currently presents an advantage to perpetrating states. Does this void or these ambiguities make cyberattacks more legally advantageous to states than traditional, kinetic weaponry? I examine whether existing IHL is sufficiently adaptable to state cyberoperations through a mixed legal and theoretical approach and conclude that they do
