"The ninth edition of A First Look at Communication Theory justifies again the program's enduring popularity. Em Griffin, now joined by colleagues Andrew Ledbetter and Glenn Sparks, encourages students who are encountering the field for the first time to tackle theories without fear. The authors introduce 32 diverse theories that are a mix of foundational and recent scholarship and, with the benefit of numerous examples and connections to pop culture, help students apply them to their own lives. This program ensures that students have a solid foundation with which to begin understanding the relationships between theories. "..

Since benchmarks drive computer science research and industry product development, which ones we use and how we evaluate them are key questions for the community. Despite complex runtime tradeoffs due to dynamic compilation and garbage collection required for Java programs, many evaluations still use methodologies developed for C, C++, and Fortran. SPEC, the dominant purveyor of benchmarks, compounded this problem by institutionalizing these methodologies for their Java benchmark suite. This paper recommends benchmarking selection and evaluation methodologies, and introduces the DaCapo benchmarks, a set of open source, client-side Java benchmarks. We demonstrate that the complex interactions of (1) architecture, (2) compiler, (3) virtual machine, (4) memory management, and (5) application require more extensive evaluation than C, C++, and Fortran which stress (4) much less, and do not require (3). We use and introduce new value, time-series, and statistical metrics for static and dynamic properties such as code complexity, code size, heap composition, and pointer mutations. No benchmark suite is definitive, but these metrics show that DaCapo improves over SPEC Java in a variety of ways, including more complex code, richer object behaviors, and more demanding memory system requirements. This paper takes a step towards improving methodologies for choosing and evaluating benchmarks to foster innovation in system design and implementation for Java and other managed languages.

This meta-analysis evaluated the relation between social support and depression in youth and compared the cumulative evidence for 2 theories that have been proposed to explain this association: the general benefits (GB; also known as main effects) and stress-buffering (SB) models. The study included 341 articles (19% unpublished) gathered through a search in PsycINFO, PsycARTICLES, ERIC, and ProQuest, and a hand search of 11 relevant journals. Using a random effects model, the overall effect size based on k = 341 studies and N = 273,149 participants was r = .26 (95% CI [.24, .28]), with robust support for the GB model and support for the SB model among medically ill youth. Stress-buffering analyses suggest that different stressful contexts may not allow youth to fully draw on the benefits of social support, and we propose value in seeking to better understand both stress-buffering (effects of social support are enhanced) and reverse stress-buffering (effects of social support are dampened) processes. Key findings regarding other moderators include a different pattern of effect sizes across various sources of support. In addition, gender differences were largely absent from this study, suggesting that social support may be a more critical resource for boys than is typically acknowledged. Results also demonstrated the importance of using instruments with adequate psychometric support, with careful consideration of methodological and conceptual issues. Building upon these collective findings, we provide recommendations for theory and practice, as well as recommendations for addressing limitations in the extant literature to guide future investigations.

Abstract Some of the most interesting work in late-20th-century epistemology reintroduced, from ancient and medieval philosophy, the idea of an intellectual virtue and the related idea of proper epistemic function. But most of that work employed such concepts, with questionable success, in the interest of defining justification, warrant, or knowledge; and little or none of it offered detailed analyses of intellectual virtues. This book proposes and illustrates a different purpose for epistemology, one that we see in early modern thinkers, especially John Locke — namely that of guiding, refining, and informing the epistemic practices of the intellectual segment of the population. One important aspect of the project of such a ‘regulative epistemology’ is the intellectual character of the epistemic agent. For this purpose, fairly detailed sketches of particular intellectual virtues and of virtues' relations to epistemic goods, epistemic faculties, and epistemic practices, gain special importance. An underlying thesis is that a strict dichotomy between the intellectual virtues and the moral virtues is a mistake.

Equivalency testing, a statistical method often used in biostatistics to determine the equivalence of 2 experimental drugs, is introduced to social scientists. Examples of equivalency testing are offered, and the usefulness of the method to the social scientist is discussed.

Greenhouse gas (GHG) emissions from post-consumer waste and wastewater are a small contributor (about 3%) to total global anthropogenic GHG emissions. Emissions for 2004-2005 totalled 1.4 Gt CO 2 -eq year —1 relative to total emissions from all sectors of 49 Gt CO 2 -eq year — 1 [including carbon dioxide (CO 2 ), methane (CH 4 ), nitrous oxide (N 2 O), and F-gases normalized according to their 100-year global warming potentials (GWP)]. The CH 4 from landfills and wastewater collectively accounted for about 90% of waste sector emissions, or about 18% of global anthropogenic methane emissions (which were about 14% of the global total in 2004). Wastewater N 2 O and CO 2 from the incineration of waste containing fossil carbon (plastics; synthetic textiles) are minor sources. Due to the wide range of mature technologies that can mitigate GHG emissions from waste and provide public health, environmental protection, and sustainable development co-benefits, existing waste management practices can provide effective mitigation of GHG emissions from this sector. Current mitigation technologies include landfill gas recovery, improved landfill practices, and engineered wastewater management. In addition, significant GHG generation is avoided through controlled composting, state-of-the-art incineration, and expanded sanitation coverage. Reduced waste generation and the exploitation of energy from waste (landfill gas, incineration, anaerobic digester biogas) produce an indirect reduction of GHG emissions through the conservation of raw materials, improved energy and resource efficiency, and fossil fuel avoidance. Flexible strategies and financial incentives can expand waste management options to achieve GHG mitigation goals; local technology decisions are influenced by a variety of factors such as waste quantity and characteristics, cost and financing issues, infrastructure requirements including available land area, collection and transport considerations, and regulatory constraints. Existing studies on mitigation potentials and costs for the waste sector tend to focus on landfill CH 4 as the baseline. The commercial recovery of landfill CH 4 as a source of renewable energy has been practised at full scale since 1975 and currently exceeds 105 Mt CO 2 -eq year —1 . Although landfill CH 4 emissions from developed countries have been largely stabilized, emissions from developing countries are increasing as more controlled (anaerobic) landfilling practices are implemented; these emissions could be reduced by accelerating the introduction of engineered gas recovery, increasing rates of waste minimization and recycling, and implementing alternative waste management strategies provided they are affordable, effective, and sustainable. Aided by Kyoto mechanisms such as the Clean Development Mechanism (CDM) and Joint Implementation (JI), the total global economic mitigation potential for reducing waste sector emissions in 2030 is estimated to be > 1000 Mt CO 2 -eq (or 70% of estimated emissions) at costs below 100 US$ t — 1 CO 2 -eq year —1 . An estimated 20—30% of projected emissions for 2030 can be reduced at negative cost and 30—50% at costs < 20 US$ t —1 CO 2 -eq year —1 . As landfills produce CH 4 for several decades, incineration and composting are complementary mitigation measures to landfill gas recovery in the short- to medium-term — at the present time, there are > 130 Mt waste year — 1 incinerated at more than 600 plants. Current uncertainties with respect to emissions and mitigation potentials could be reduced by more consistent national definitions, coordinated international data collection, standardized data analysis, field validation of models, and consistent application of life-cycle assessment tools inclusive of fossil fuel offsets.

The US tolerates more inequality than Europe and believes its economic mobility is greater than Europe's, though they had roughly equal rates of intergenerational occupational mobility in the late twentieth century. We extend this comparison into the nineteenth century using 10,000 nationally-representative British and US fathers and sons. The US was more mobile than Britain through 1900, so in the experience of those who created the US welfare state in the 1930s, the US had indeed been “exceptional.” The US mobility lead over Britain was erased by the 1950s, as US mobility fell from its nineteenth century levels.

Abstract Part I: A new technique is developed for evaluating the integrals which occur in molecular theory. The method is based on the expansion of exponentials in terms of the so-called £ functions. These involve modified Bessel functions. In this part we list the properties of these £ functions needed for the two-centre integrals. A table is provided of the I’s and K’s used in their tabulation. An account is given of the properties of certain integrals of the £ functions and some numerical examples are provided. Part II: Methods are described for the evaluation of the two-centre, one-electron Coulomb, overlap and resonance integrals, for the two-electron Coulomb and hybrid (Coulomb-exchange) integrals, and for the penetration integrals. Formulae are listed for more than 180 distinct integrals.

Abstract Examines the emergence – and then the broad effects – of a singularly American synthesis of convictions. That synthesis of evangelical Protestant religion, republican political ideology, and commonsense moral reasoning came into existence during the second half of the eighteenth century and then exerted a telling influence on American life through the time of the Civil War. Elsewhere in the North Atlantic world, the main Christian traditions opposed both “Real Whig” republicanism and the “commonsense” principles of the era's new moral philosophy. Not so in America. Through a series of contingent circumstances – revival in the 1740s, colonial warfare with France, the struggle for independence, a great surge of evangelical denominations in the new republic, and the leadership of Protestant thought and agencies in creating a national culture – distinctly American forms of Christian republicanism and theistic common sense became the common intellectual coinage of the new United States. In turn, these patterns of thought pushed theology, for both educated elites and sectarian populists, toward greater stress on the individual, on free will, and on personal appropriation of the Bible. The very centrality of commonsense Christian republicanism also, however, set the stage for the intellectual tragedy of the Civil War – when dedicated Christians, both North and South, were convinced that the Bible supported only their own side. The story is at once a great triumph of creative theological energy and a significant tragedy of theology captured by culture.

Human listeners can effortlessly categorize a wide range of environmental sounds. Whereas categorizing visual object classes (e.g., faces, tools, houses, etc.) preferentially activates different regions of visually sensitive cortex, it is not known whether the auditory system exhibits a similar organization for different types or categories of complex sounds outside of human speech. Using functional magnetic resonance imaging, we show that hearing and correctly or incorrectly categorizing animal vocalizations (as opposed to hand-manipulated tool sounds) preferentially activated middle portions of the left and right superior temporal gyri (mSTG). On average, the vocalization sounds had much greater harmonic and phase-coupling content (acoustically similar to human speech sounds), which may represent some of the signal attributes that preferentially activate the mSTG regions. In contrast, correctly categorized tool sounds (and even animal sounds that were miscategorized as being tool-related sounds) preferentially activated a widespread, predominantly left hemisphere cortical "mirror network." This network directly overlapped substantial portions of motor-related cortices that were independently activated when participants pantomimed tool manipulations with their right (dominant) hand. These data suggest that the recognition processing for some sounds involves a causal reasoning mechanism (a high-level auditory "how" pathway), automatically evoked when attending to hand-manipulated tool sounds, that effectively associates the dynamic motor actions likely to have produced the sound(s).

Although many recent studies have emphasized the multiplicity of institutional logics and the competition among them, how some institutional logics become prioritized over others in shaping organizational decisions is undertheorized. Drawing on panel data of 118 industrial facilities across 34 communities in Texas and Louisiana, we show that the saliency of different kinds of community logics significantly affects environmental practices—specifically, toxic waste emissions—of facilities in a community. Our results show that community logics not only have direct effects but also have indirect effects by filtering organizational reactions to broader field-level institutional logics. We theorize how community logics can amplify or dampen the influence of broader field-level logics and discuss the implications for the study of institutional complexity, social movements, and values in the configuration of institutional logics.

In this article, we summarize the work of the NASA Outer Planets Assessment Group (OPAG) Roadmaps to Ocean Worlds (ROW) group. The aim of this group is to assemble the scientific framework that will guide the exploration of ocean worlds, and to identify and prioritize science objectives for ocean worlds over the next several decades. The overarching goal of an Ocean Worlds exploration program as defined by ROW is to "identify ocean worlds, characterize their oceans, evaluate their habitability, search for life, and ultimately understand any life we find." The ROW team supports the creation of an exploration program that studies the full spectrum of ocean worlds, that is, not just the exploration of known ocean worlds such as Europa but candidate ocean worlds such as Triton as well. The ROW team finds that the confirmed ocean worlds Enceladus, Titan, and Europa are the highest priority bodies to target in the near term to address ROW goals. Triton is the highest priority candidate ocean world to target in the near term. A major finding of this study is that, to map out a coherent Ocean Worlds Program, significant input is required from studies here on Earth; rigorous Research and Analysis studies are called for to enable some future ocean worlds missions to be thoughtfully planned and undertaken. A second finding is that progress needs to be made in the area of collaborations between Earth ocean scientists and extraterrestrial ocean scientists.

Cyberbullying has become a common occurrence among adolescents worldwide; however, it has yet to receive adequate scholarly attention in China, especially in the mainland. The present study investigated the epidemiological characteristics and risk factors of cyberbullying, utilizing a sample of 1,438 high school students from central China. Findings revealed that cyberbullying among high school students in the heartland of central China is relatively common with 34.84% ( N = 501) of participants reported having bullied someone and 56.88% ( N = 818) reported having been bullied by online. Significant gender differences were found, suggesting that boys are more likely to be involved in cyberbullying both as perpetrators and victims. Students with lower academic achievement were more likely to be perpetrators online than were students with better academic achievement. Students who spend more time on online, have access to the internet in their bedrooms, have themselves experienced traditional bullying as victims, and are frequently involved in instant-messaging and other forms of online entertainment are more likely to experience cyberbullying. Increased parent and teacher supervision reduced students’ involvement in cyberbullying. Implications for intervention are explored.

The question of whether particular types of legal institutions influence the effectiveness of the rule of law has long been answered with conjecture. Common law lawyers and judges tend to believe that the common law system is superior. This opinion is based on the idea that the common law system inherited from the British is more able to protect the rights of the individual than civil law judicial systems. Quite the opposite point of view can be found in lawyers from civil law countries, who may view the common law system as capricious and disorganised. This paper compares the effectiveness of the rule of law in common law and civil law countries in Africa, through a cross-national statistical comparison using Freedom House and Political Risk Services data. The comparison reveals that common law countries in Africa are generally better at providing ‘rule of law’ than are civil law countries.

Instead of focusing on students’ citation of sources, educators should attend to the more fundamental question of how well students understand their sources and whether they are able to write about them without appropriating language from the source. Of the 18 student research texts we studied, none included summary of a source, raising questions about the students’ critical reading practices. Instead of summary, which is highly valued in academic writing and is promoted in composition textbooks, the students paraphrased, copied from, or patchwrote from individual sentences in their sources. Writing from individual sentences places writers in constant jeopardy of working too closely with the language of the source and thus inadvertently plagiarizing; and it also does not compel the writer to understand the source.

Abstract The membrane surrounding the nucleus of the oocytes of two species of amphibian is shown to consist of two structures, an outer porous layer and an inner layer which is apparently continuous. The porous layer is about twice as thick as the inner layer, the dried membrane as a whole having a thickness of approximately 500 Å. The pores are of regular size and arrangement in the outer layer; pore diameter is approximately 400 Å, the separation distance between pore centres 1000 Å. Both layers consist of relatively insoluble protein materials, the porous layer also containing some lipoid.

Purpose This research employs a transformative service lens to examine the role of the supply chain ecosystem in ensuring the health and safety of employees and customers as a well-being outcome during the coronavirus disease of 2019 (COVID-19) pandemic. Design/methodology/approach This is a conceptual paper examining the response of the supply chain to the current food crisis caused by the pandemic. Findings Based on the service-dominant logic (SDL) paradigm, the COVID-19 examination of the supply chain ecosystem provides a foundation for further research employing a transformative lens. Research limitations/implications The COVID-19 situation is primarily explored from a Western, educated, industrialised, rich and democratic (WEIRD) societies’ context. Future research should explore the applicability of the transformative service lens to other societies. Practical implications The conceptual discussion and research agenda provide direction for researchers, practitioners and policymakers towards a transformative supply chain ecosystem. Originality/value This research includes the well-being of employees and customers in the service supply chain outcome measures, draws supply chain management into the TSR domain, while also solidifies a service ecosystem perspective of supply chain management.

Recent technological advances in the power generation and information technologies areas are helping to change the modern electricity supply system in order to comply with higher energy efficiency and sustainability standards. Smart grids are an emerging trend that introduce intelligence in the power grid to optimize resource usage. In order for this intelligence to be effective, it is necessary to retrieve enough information about the grid operation together with other context data such as environmental variables, and intelligently modify the behavior of the network elements accordingly. This article presents a multi-agent system model for virtual power plants, a new power plant concept in which generation no longer occurs in big installations, but is the result of the cooperation of smaller and more intelligent elements. The proposed model is not only focused on the management of the different elements, but includes a set of agents embedded with artificial neural networks for collaborative forecasting of disaggregated energy demand of domestic end users, the results of which are also shown in this article.
