Electricity supply offers significant and immense benefits to human society, and it is instrumental in driving economic growth, increased standard of living and technological developments. Its sustainable supply and consumption is related to many ecological discussions, and thus, present emphasis on renewable sources, such as solar and hydro. In Nigeria, however, challenges associated with electricity generation, transmission, distribution and consumption have not been adequately tackled. Poor electricity supply has adversely impacted the economy resulting to poor production, higher prices of goods and services, closure of industries, and loss of competitive advantage of Nigerian businesses. Conversely, energy-inefficient and non-conservation consumption behaviour of Nigerian electricity consumers contributes to the electricity demand - demand gap. Energy-efficiency and conservation is a sustainable tool for efficient power system. The paper show that the use of mostly post-paid and unmetered billing system is implicated in energy-inefficient consumption. The paper advocates for deployment of pre-paid meters to every electricity consumer; fiscal management, enforcement of energy saving policies such as use of compact fluorescent lamps (CFL); and emphasis on renewable energy (hydro and solar) sources, for electricity generation.

Deception is a frequent but under appreciated aspect of human society (Eckman, 2001). Deception in electronic goods and services is facilitated by the difficulty of verifying details in the limited information available in cyberspace (Mintz, 2002). Fear of being deceived (often unjustified) is in fact a major obstacle to wider use of e-commerce and e-government by the public. One survey reported consumers thought fraud on the Internet was 12 times more common than offline fraud, and 3 out of 5 people thought their credit card number could be stolen in most online transactions (Allen, 2001); both are overestimates. We assess here the nature of the deception threat, how deception can be detected, and what can be done about it.

Cultural studies seeks to understand and explain how culture relates to the larger society and draws on social theory, philosophy, history, linguistics, communication, semiotics, media studies, and more to assess and evaluate mass media and everyday cultural practices. Since its inception in 1960s Britain, cultural studies has had recognizable and recurring interactions with Marxism, most clearly in culturalist renderings along a spectrum of tensions with political economy approaches. Marxist traditions and inflections appear in the seminal works of Raymond Williams and E. P. Thompson, work on the culture industry inspired by the Frankfurt School in 1930s Germany, challenges by Stuart Hall and others to the structuralist theories of Louis Althusser, and writings on consciousness and social change by Georg Lukács. Perhaps the most pronounced indication of Marxist influences on cultural studies appears in the multiple and diverse interpretations of Antonio Gramsci’s concept of hegemony. Cultural studies, including critical theory, has been invigorated by Marxism, even as a recurring critique of economic determinism appears in most investigations and analyses of cultural practices. Marxism has no authoritative definition or application. Nonetheless, Marxism insists on materialism as the precondition for human life and development, opposing various idealist conceptions whether religious or philosophical that posit magical, suprahuman interventions that shape humanity or assertions of consciousness, creative genius, or timeless universals that supersede any particular historical conjuncture. Second, Marxism finds material reality, including all forms of human society and culture, to be historical phenomenon. Humans are framed by their conditions, and in turn, have agency to make social changing using material, knowledge, and possibilities within concrete historical conditions. For Marxists, capitalist society can best be historically and materially understood as social relations of production of society based on labor power and capitalist private ownership of the means of production. Wages paid labor are less than the value of goods and services produced. Capitalist withhold their profits from the value of goods and services produced. Such social relations organize individuals and groups into describable and manifest social classes, that are diverse and unstable but have contradictory interests and experiences. To maintain this social order and its rule, capitalists offer material adjustments, political rewards, and cultural activities that complement the social arrangements to maintain and adjust the dominant social order. Thus, for Marxists, ideologies arise in uneasy tandem with social relations of power. Ideas and practices appear and are constructed, distributed, and lived across society. Dominant ideologies parallel and refract conflictual social relations of power. Ideologies attune to transforming existing social relations may express countervailing views, values, and expectations. In sum, Marxist historical materialism finds that culture is a social product, social tool, and social process resulting from the construction and use by social groups with diverse social experiences and identities, including gender, race, social class, and more. Cultures have remarkably contradictory and hybrid elements creatively assembled from materially present social contradictions in unequal societies, ranging from reinforcement to resistance against constantly adjusting social relations of power. Five elements appear in most Marxist renditions on culture: materialism, the primacy of historical conjunctures, labor and social class, ideologies refracting social relations, and social change resulting from competing social and political interests.

Abstract Invasive non-native species and global warming are two of the greatest components of global ecosystem change. The Pacific oyster, Crassostrea gigas, is the world most cultivated shellfish and was introduced throughout the Northwest European Shelf (NWES) under the premise it could not complete its life cycle. Recent warming trends have changed this and wild populations can be found as far north as Nordic Scandinavia. Under the RCP8.5 concentration pathway, we predict that the majority of NWES coastline will be within C. gigas’s thermal recruitment niche by 2100. Given the widespread occurrence of current naturalized C. gigas populations, its large larval dispersal potential and a lack of feasible management solutions, C. gigas will likely undergo a considerable range expansion this century. The time taken to reach maturity is predicted to decrease by up to 60 days, which may lead to precocious spawning events, facilitating expansion further. Crassostrea gigas can form extensive reefs completely transforming native systems. This may compromise native biodiversity, protected habitats, and commercial species. However, naturalization can also deliver a number of beneficial ecosystem goods and services to human society. Whether naturalization is deemed positive or negative will depend on biogeographic context, the perceptions of stakeholders, and the wider management priorities.

There is not a great deal to be said about economics which is truly universal. One can say that economics is the study of economic systems. Economic systems can be defined as systems of human actions concerned with the production and the distribution of goods and services which are scarce relative to the wants of the community. But statements of this kind, which attempt to define the economic aspect of human society in universally valid terms, are far too general to serve as premises from which an economic theory, useful for understanding actual economic problems, can be logically deduced. To have theory, one must start with premises and assumptions about some particular economic system, historically given, or some particular kind of economic system. The great bodies of economic thought of the Western world—mercantilism, classical and neo-classical economic liberalism, and the various schools of Marxist economic—have been theories relevant to particular economic systems: those, let us say, of the Western world in the seventeenth, eighteenth, and nineteenth centuries.

Research on the basic interaction of radiation with biological systems has contributed to human society through various applications in medicine, agriculture, pharmaceuticals and in other technological developments. In the agricultural sciences and food technology sectors, recent research has elucidated the new potential application of radiation for microbial decontamination due to the inhibitory effect of radiation on microbial infestation. The last few decades have witnessed a large number of pertinent works regarding the utilization of radiation with special interest in γ-rays for evolution of superior varieties of agricultural crops of economic importance. In this review, general information will be presented about radiation, such as plant specificity, dose response, beneficial effects, and lethality. A comparison of different studies has clarified how the effects observed after exposure were deeply influenced by several factors, some related to plant characteristics (e.g., species, cultivar, stage of development, tissue architecture, and genome organization) and some related to radiation features (e.g., quality, dose, duration of exposure). There are many beneficial uses of radiation that offer few risks when properly employed. In this review, we report the main results from studies on the effect of γ-irradiations on plants, focusing on metabolic alterations, modifications of growth and development, and changes in biochemical pathways especially physiological behaviour.

Electricity is the fundamental need of human society. Any nation's growth depends on energy. The worldwide electricity consumption increases and conventional electricity sources are causing pollution. Therefore, some non-conventional energy recourses are mandatory to be designed and developed for electricity generation, and they are useful and environment-friendly. In this study, a renewable, non-conventional energy source prototype has been developed, based on the mechanism of power generation from speed breaker with ratchet and pawl mechanism. This study aims to convert the kinetic energy of vehicles into electrical energy which can be used for street and highway lighting and conservation of electrical energy.

This research assesses the social impacts that could arise from the potential waste-to-energy (WtE) generation of electricity from municipal solid waste (MSW) in the cities of Lagos and Abuja in Nigeria. Social life cycle assessment (sLCA) was the main analytical approach used coupled with a participatory approach to identify relevant social issues to serve as the potential sLCA impact ‘subcategories’. Focus group research in both cities led to the identification of 11 social issues that were transformed into social impact subcategories with appropriate indicators for the sLCA. These were populated with data from a questionnaire-based survey with approximately 140 stakeholders. The results indicated that the impact subcategories “Improved Electricity Supply” and “Income” were ranked respectively as having the most and the least significant social impacts associated with the potential adoption of WtE in these two cities in Nigeria. Overall, the research showed that the expected social impact was higher for WtE electricity generation in Lagos than in Abuja. This difference may be related to the higher population and greater amounts of waste in Lagos and its position as a hub for many of the country’s commercial and industrial activities which have long been affected by inadequate electricity supply. This study also provides an example of the use of participatory processes as an important approach in sLCA for the elucidation of social issues that are directly pertinent to key local perspectives when considering such technology implementations.

<em>The millennial generation is the generation that has dominated the labor market in recent years. This generation is being faced with various challenges due to technological developments that are happening.</em> <em>Current technological developments are forcing the players in the goods and service industries to innovate in order to be able to increase the competitiveness of companies. Innovative work behavior can be raised</em> <em>by individuals in several ways, one of which is with a proactive personality. This study aims to measure the</em> <em>relationship between proactive personality with innovative work behavior in the millennial generation. The study was conducted on 315 millennials who are full time employees in goods and services companies in the city of Surabaya. Innovative work behavior is measured using the Innovative Work Behavior Scale, which is proven to be reliable (α = 0.760), while the proactive personality is measured using the Proactive Personality Scale that has proven to be reliable (α = 0.734). The analysis in this study uses Pearson's Product Moment analysis with a significance value of 0,000 (p &lt;0.05) which shows the relationship between proactive personality and innovative work behavior in the millennial generation. These results indicate that the higher the proactive personality an individual has, the higher the innovative work behavior exhibited by the individual. The results of this study also found a significant relationship between sex, years of service and age on innovative work behavior</em>

Some years inspire more hindsight reflection and future-gazing than others. This is even more so in 2020 with its evocation of perfect vision and the landmark ring to it. However, no futurist can reliably predict what the world will look like the next time that a year’s first two digits will match the second two digits—a numerical pattern that only occurs once in a century. As we leap into a new decade, amid uncertainties triggered by unforeseen global events—such as the outbreak of a worldwide pandemic, the accompanying economic hardship, and intensifying geopolitical tensions—it is important to note the blistering pace of 21st century technological developments indicate that while hindsight might be 20/20, foresight is 50/50. The history of science shows us that imaginative ideas, research excellence, and collaborative innovation can, for example, significantly contribute to the economic, cultural, social, and environmental recovery of a post-COVID-19 world. This article reflects on a history of yeast research to indicate the potential that arises from advances in science, and how this can contribute to the ongoing recovery and development of human society. Future breakthroughs in synthetic genomics are likely to unlock new avenues of impactful discoveries and solutions to some of the world’s greatest challenges.
