After the United States Congress passed the Water Pollution Control Act of 1948, biologists played an increasingly significant role in scientific studies of water pollution. Biologists interacted with other experts, notably engineers, who managed the public agencies devoted to water pollution control. Although biologists were at first marginalized within these agencies, the situation began to change by the early 1960s. Biological data became an integral part of water pollution control. While changing societal values, (...) stimulated by an emerging ecological awareness, may explain broader shifts in expert opinion during the 1960s, this article explores how graphs changed experts’ perceptions of water pollution. Experts communicated with each other via reports, journal articles, and conference speeches. Those sources reveal that biologists began experimenting with new graphical methods to simplify the complex ecological data they collected from the field. Biologists, I argue, followed the engineers’ lead by developing graphical methods that were concise and quantitative. Their need to collaborate with engineers forced them to communicate, negotiate, and overcome conflicts and misunderstandings. By meeting engineers’ expectations and promoting the value of their data through images as much as words, biologists asserted their authority within water pollution control by the early 1960s.

In recent years, the problem of environmental pollution has become more and more serious, and environmental pollution has become a topic of concern. PM2.5, PM10, hazy weather, and other words about environmental pollution have become hot words and topics for the media and the public to talk about, and environmental pollution control is called for by the media and the public. This reflects the rapid development of economy and the obvious changes in people’s living standards, (...) and people have higher requirements and aspirations for their lives and the environment they live in, and their awareness of environmental protection is getting stronger and stronger; however, it also reflects that the rapid development of the economy comes at the cost of damaging the environment. This paper analyzes the current situation and governance dilemma of rural environment by means of field research from dynamic portfolio evaluation theory, explains the problems and causes of environmental pollution management under the requirement of polycentric governance, and proposes countermeasures to solve the problem of environmental pollution management in county. The paper aims to analyze the current state of environmental pollution in rural areas through literature review, villagers’ field interviews, and field research and to explain the application of polycentric governance to rural environmental pollution management in county in the region.

This paper makes a contribution to ongoing debates about whether and how we can empirically assess the potential, limitations, and actual impacts of public-private partnerships in developing countries. Several United Nations and bilateral aid agencies have called for the development of impact assessment methodologies that can help clarify when, how, where, and for whom partnerships work. This paper scrutinizes some of the key assumptions underlying this debate, arguing that no objective ' truth' about the effects of PPPs can be discovered (...) through the use of such methodologies. The paper then investigates what can actually be known about a PPP's effects by testing a PPP IA framework that is recommended by the Organization for Economic Cooperation and Development. This is done using a case study from Pakistan. The paper shows that IA methodology may provide an indication of how well a PPP has fared, but not why the PPP has turned out the way it has. At the same time, win-win and win-lose outcomes may exist simultaneously, even for the same stakeholder in the PPP. While the importance of ensuring proper design, monitoring, and IA of PPPs cannot be denied, their effects must be seen as an outcome of struggles between a variety of actors over the distribution of social and environmental hazards associated with broader processes of economic development and industrialization.

Dispassionate cruelty and the euphoria of hunting or battle should be distinguished from the emotional savoring of victims' suffering. Such savoring, best called negative empathy, is what puzzles motivational theory. Hyperbolic discounting theory suggests that sympathy with people who have unwanted but seductive traits creates a threat to self-control. Cruelty to those people may often be the least effortful way of countering this threat.

Este artigo é o recorte de uma pesquisa maior que se caracteriza como sendo pós-crítica. O texto busca, por meio de uma análise das falas de estudantes do 3º ano do “Programa Ensino Médio Inovador”, de uma escola pública estadual do Município de Blumenau – SC, evidenciar os discursos de performatividade aí presentes. A cultura de performatividade, emergente do setor econômico-empresarial e espraiada para setores públicos/estatais, é entendida como um dispositivo que atua na regulação e no controle dos corpos, produzindo (...) os sujeitos desejáveis para a atual sociedade neoliberal. Ao estimular a excelência, a competitividade, o julgamento, a qualidade e o resultado, essa cultura contribui para que a escola se torne um grande negócio de seleção e meritocracia. Por meio de uma pesquisa cartográfica e com registros em diário de campo, este artigo objetiva problematizar quais subjetividades estão sendo produzidas pela escola contemporânea a partir de um dado currículo, e, então, desafiar o pensamento na construção de subjetividades outras, possibilidades de re-existência, para além dos números, cifras e estatísticas. O artigo divide-se em uma seção introdutória ao tema da governamentalidade, uma seção em que se contextualiza a sociedade contemporânea e a função da escola e do currículo; outra que apresenta a análise de falas de estudantes; e, por fim, alguns questionamentos que consideram a escola uma maquinaria que produz muito e produz tudo. Pode produzir aquilo que se espera para esta sociedade, o sujeito performático, consumidor da racionalidade neoliberal, assim, como pode produzir linhas de fuga, resistências, imposturas éticas contra condutas ao que está posto.

A formação docente pode ser analisada sob várias perspectivas. Neste artigo procura-se enfocar a formação docente como um instrumento político de manipulação e de controle das racionalidades e subjetividades dos sujeitos em formação. Procura-se entender essa dominação sobre seus alunos. Trata-se de um exercício estratégico de biopoder exercido por uma governamentalidade dominante. Este papel das formações parece ser um dos principais elementos motivadores das licenciaturas e das formações continuadas de docentes no Brasil. A mobilização das racionalidades e subjetividades esperada pela (...) governamentalidade gera estratificações nas relações entre os atores envolvidos com educação, criando grupos definidos de cooperação e rompimentos entre os sujeitos. A formação como um espaço de manifestação dos dispositivos disciplinares e de poder são identificados nas ações de formação docente e correspondem à estratificação e à manutenção do biopoder de controle das racionalidades e das subjetividades do indivíduo. O objetivo deste trabalho é analisar as condições da existência do poder exercido sobre as formações docentes. Busca-se reconhecer três formas estratégicas através das quais estes dispositivos de disciplinamento são exercidos. A primeira se dá em relação ao posicionamento dos formadores e formandos em questões étnicas, sociais e religiosas que estabelecem padrões éticos e morais aceitáveis pela governamentalidade. A segunda, pelas formas de dominação exercidas nas formações docentes que tendem a separar os indivíduos de seus produtos intelectuais e subjetividades. A terceira, pelas formas de sujeição praticadas em relação ao indivíduo mobilizadas externamente pelas instituições ou internamente pelo próprio indivíduo submetido ao processo formativo, assegurando sua submissão ao biopoder dominante.

In spectrum sharing cognitive radio networks, unauthorized users are allowed to use the spectrum of authorized users to improve spectrum utilization. Due to limited spectrum resources, how to formulate a reasonable spectrum allocation scheme is very important. As a mathematical analysis tool, game theory can solve the problem of resource allocation well. In recent years, it has been applied to the research of resource allocation in spectrum sharing networks by some literatures. In a cellular network consisting of multiple cellular users (...) and full-duplex end-to-end communication users D2D, the self-interference caused by full-duplex communication and the interference caused by the D2D users to the cellular users will significantly reduce system throughput. In order to reduce the interference in the network, this paper introduces a power control algorithm based on Stackelberg game, which sets the cellular users and D2D users as the leaders and followers, respectively. The cellular users and the D2D users compete with each other to minimize the cost, and we propose new utility functions. We build an optimization problem under the outage probability constraint and power constraint and the transmission power of the users is obtained by using the Lagrangian dual decomposition method. The simulation results show that the proposed game algorithm improves network performance compared with other existing schemes. (shrink)

The United States Environmental Protection Agency has begun to encourage innovative market-based approaches to address nonpoint source water pollution. These water quality trading programs have the potential to achieve environmental standards at a lower overall cost. Two fundamental questions must be answered before these benefits can be realized: How will trades between point and nonpoint sources be monitored and enforced? and, How will nonpoint sources be included within a trading market? ;Point-nonpoint source trading can be accommodated through either a (...) technology-based or performance-based approach. The technology-based approach accommodates trading through the use of a proxy for unobservable, individual nonpoint source emission reductions. While trading ratios can effectively deal with the uncertainty associated with using a proxy for actual abatement, they are inefficient and ineffective for dealing with problems of hidden action. The alternative use of performance-based trading approaches requires the use of team contracts that provide individual incentives linked to the performance of the entire group. Such contracts must be designed to overcome both adverse selection and moral hazard problems. Performance-based approaches promise efficiency gains in terms of reducing the problems of asymmetric information, and by introducing flexibility into the choice of nonpoint source abatement technologies and practices. ;Nonpoint sources are exempted from direct regulation under the polluter-pays-principle. As a result, their participation in trading markets is voluntary, thus preventing a baseline cap on pre-trade emissions. To determine whether this arrangement should be changed, we must ask if there something that morally prohibits the direct regulation of nonpoint sources of pollution. While a morally relevant distinction can be made between point and nonpoint sources of emission based on differences in the ability to observe individual emission levels, this relevance is limited to the case of performance-based policy instruments. The moral legitimacy of applying the polluter-pays-principle to nonpoint sources of pollution must be made on a case by case basis, as it is dependent upon existing social, economic, and other practical factors. However, it can be stated that there is no general moral barrier to prohibit the application of the polluter-pays-principle to nonpoint sources of pollution. (shrink)

The last decade has witnessed the mass distribution and adoption of smart home systems and devices powered by artificial intelligence systems ranging from household appliances like fridges and toasters to more background systems such as air and water quality controllers. The pervasiveness of these sociotechnical systems makes analyzing their ethical implications necessary during the design phases of these devices to ensure not only sociotechnical resilience, but to design them for human values in mind and thus preserve meaningful human (...) control over them. This paper engages in a conceptual investigations of how meaningful human control over smart home devices can be attained through design. The value sensitive design (VSD) approach is proposed as a way of attaining this level of control. In the proposed framework, values are identified and defined, stakeholder groups are investigated and brought into the design process and the technical constraints of the technologies in question are considered. The paper concludes with some initial examples that illustrate a more adoptable way forward for both ethicists and engineers of smart home devices. (shrink)

Commitment devices (CDs) can help people overcome self-control problems to act on their plans and preferences. In these arrangements, people willingly make one of their options worse in order to change their own future behaviour, often by setting aside a sum of money that they will forfeit it if they fail to complete the planned action. Such applications of behavioural science have been used to help people stick to healthier lifestyle choices, overcome addictions and adhere to medication; they (...) are acceptable to many patients and even relatively small sums can be effective. Some authors have objected to the use of nudges in healthcare. Engelen has listed nine potential objections to nudges in relation to means (why nudge rather than persuade?), ends (what action is being promoted?) and agents (who is nudging whom?). These objections are shown to lack force in the context of CDs. Instead, an analysis specific to the ethical issues in CDs is employed. CDs exclude certain groups including so-called ‘naifs’ and risk increasing health inequality. CDs may promote the wrong behaviour and people might legitimately change their minds. Intermediaries might encounter perverse incentives. Approaches to overcoming these problems are described and eight key ethical considerations for those considering implementing CDs in the future are described. Altogether this paper illustrates the advantages of appraising the ethics of behavioural science in medicine on a case-by-case basis. (shrink)

We investigate whether air pollution harms business ethics from the perspective of earnings manipulation, which exerts a real effect on the economy and social welfare. Using a large sample and a comprehensive air quality index in China, we find that firms located in cities with more severe air pollution exhibit higher levels of discretionary accruals and are more likely to restate their financial statements, consistent with exposure to air pollution leading to more earnings manipulation. We further provide (...) causal evidence using propensity score matching and a discontinuity regression design exploiting the Qinling Mountain–Huai River Heating Policy Line, which exogenously leads to more air pollution to cities located immediately north of the Line but not those in the south. Our findings are robust to controlling for weather conditions and alternative samples and measures of air pollution and earnings manipulation. Overall, this study unveils how the ecological environment shapes business ethics. (shrink)

I offer a new proposal to prevent some of the harms of gun violence in the United States. First, I argue that gun violence is a negative externality of gun production, on an analogy with industrial pollution. Second, I outline a law that the United States might use to internalize the violent costs of gun production. This law would provide a financial incentive for gun manufacturers to reduce gun violence in whatever legally permissible way they can, not necessarily by (...) reducing the prevalence of gun ownership. Thus, strictly speaking, my proposal would be a form of gun violence control, not gun control per se. Third, I show that this approach to controlling gun violence avoids the three main pro-gun-rights arguments: the Consequentialistic Argument, the Moral Rights Argument, and the Legal Rights Argument. I conclude by explaining why even libertarians should have few principled objections to my proposal. (shrink)

This paper empirically raises and examines the question of ‘conceptual control’: To what extent are competent thinkers able to reason properly with new senses of words? This question is crucial for conceptual engineering. This prominently discussed philosophical project seeks to improve our representational devices to help us reason better. It frequently involves giving new senses to familiar words, through normative explanations. Such efforts enhance, rather than reduce, our ability to reason properly, only if competent language users are able (...) to abide by the relevant explanations, in language comprehension and verbal reasoning. This paper examines to what extent we have such ‘conceptual control’ in reasoning with new senses. The paper draws on psycholinguistic findings about polysemy processing to render this question empirically tractable and builds on recent findings from experimental philosophy to address it. The paper identifies a philosophically important gap in thinkers’ control over the key process of stereotypical enrichment and discusses how conceptual engineers can use empirical methods to work around this gap in conceptual control. The paper thus empirically demonstrates the urgency of the question of conceptual control and explains how experimental philosophy can empirically address the question, to render conceptual engineering feasible as an ameliorative enterprise.

Air pollution has become a serious issue that affects billions of people worldwide. The relationship between air pollution and social behaviour has become one of the most widely discussed topics in the academic community. While the link between air pollution and risk-averse and unethical behaviours has been explored extensively, the relationship between air pollution and prosocial behaviour has been examined less thoroughly. Individual blood donation is a typical form of prosocial behaviour. We examined the effect of (...) air pollution on prosocial behaviour using the Poisson regression quasi-maximum likelihood based on the panel data related to air pollution and blood donations. We also employed a set of control variables and robustness checks. The findings indicate that air pollution does not affect whole blood donation, although it does affect component blood donation. We also find that the effect of air pollution on blood donation is heterogeneous in terms of gender, age, and other factors. These results show that the relationship between air pollution and prosocial behaviour is limited. Not all types of prosocial behaviour are affected by air pollution, perhaps because air pollution affects only specific psychological motivations and because different types of prosocial behaviour have different motivations.

We describe a new class of experiments designed to probe the foundations of quantum mechanics. Using quantum controlling devices, we show how to attain a freedom in temporal ordering of the control and detection of various phenomena. We consider wave–particle duality in the context of quantum-controlled and the entanglement-assisted delayed-choice experiments. Then we discuss a quantum-controlled CHSH experiment and measurement of photon’s transversal position and momentum in a single set-up.

Wandering is a symptom of dementia that can have devastating consequences on the lives of persons living with dementia and their families and caregivers. Increasingly, caregivers are turning towards electronic tracking devices to help manage wandering. Ethical questions have been raised regarding these location-based technologies and although qualitative research has been conducted to gain better insight into various stakeholders' views on the topic, developers of these technologies have been largely excluded. No qualitative research has focused on developers’ perceptions of (...) ethics related to electronic tracking devices. To address this, we performed a qualitative semi-structured interview study based on grounded theory. We interviewed 15 developers of electronic tracking devices to better understand how they perceive ethical issues surrounding the design, development, and use of these devices within dementia care. Our results reveal that developers are strongly motivated by moral considerations and believe that including stakeholders throughout the development process is critical for success. Developers felt a strong sense of moral obligation towards topics within their control and a weaker sense of moral obligation towards topics outside their control. This leads to a perceived moral boundary between development and use, where some moral responsibility is shifted to end-users. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Purity and Pollution: Resisting the Rehabilitation of a VirtueAmy Mullin“Purity” is a term used infrequently in contemporary academic literature. A survey of periodical indexes for the past ten years shows that references to purity occur predominantly in metallurgy. Purity is an increasingly important topic in anthropology, religious studies, and history, but it is a decidedly rare concern in philosophy. In my most recent search I found three references.Yet (...) “purity” was once a recurrent term in the philosophical tradition ranging from Plato through Augustine and Kant to Kierkegaard. Today when we encounter the many references to purity in the history of philosophy we too often filter them out. We assume either that “pure” is a generic term for good, or, in what seems a more knowing and sophisticated response, we read “pure” as a code term for chastity or sexual morality, the elimination, suppression or control of sexual desire. In both cases purity is written off either as a generic or as an old fashioned and rather embarrassing virtue. Hence it seems there is little reason for contemporary philosophical investigation into the rhetorical use of the language of purity and pollution.Three assumptions account for the lack of contemporary philosophical interest in the topic. First, it is assumed that purity is no longer a concern in twentieth-century philosophy. Second, purity in historical discourse is considered to be limited to a prudish or downright misogynist hostility to sex. Third and finally, it is assumed that the work historians and anthropologists have done recently into connections between purity beliefs and practices and social cohesion is irrelevant for philosophy. This is because purity in philosophy is supposed to be a resolutely individualist virtue, having little or nothing to do with unified and coherent communities.There are elements of truth to all three beliefs, but they also contain important distortions of the truth. As regards the first assumption, purity remains a concern in contemporary aesthetics, where it often means roughly something like a priori and apolitical; but I am interested in whether the concern with purity has survived in philosophies with ethical implications. [End Page 509] Here it is my contention that authenticity is the twentieth-century descendant of the virtue of purity.Second, there is much more to the rhetoric and practices of purity than concern with the sexual dimension of life, though this is a key aspect of most, and the beliefs and practices are often misogynist. There have been numerous anthropological documentations of ways in which purity beliefs, particularly an emphasis on sexual purity, are used to control women. Santi Rozario’s work, for instance, makes this point in her analysis of contemporary Bengali village life. 1 The connection between the language of purity and the practice of female circumcision, which I will not discuss in this paper, is in itself evidence enough of connections between purity beliefs and practices harmful to women. 2 However, I hope to show that there is more to purity than misogyny. Purity most basically is about order, both social and personal. 3My response to the second assumption, that purity masks an obsession with sexual control, indicates the source of my disagreement with the third, the contention that purity in philosophy is exclusively an individual virtue. Communal beliefs and practices associated with the language of purity and pollution are relevant to the philosophical treatment of purity because of the presence in both the practices and the philosophies of an interplay between social and personal order. As a result I believe an understanding of the dynamics of beliefs about purity in social practice can inform a philosophical concern with purity.First I investigate shifts in beliefs and practices concerning purity and pollution. I will concentrate on three models: ancient Greek (from the eighth to the third century BC), biblical to Talmudic Judaism (from the third century BC to the third century AD), and early Christian (from the first to the fifth century AD). These represent three traditions which have played a very significant role in shaping western civilization, theology, and philosophy. 4 They were also frequently interrelated in this period, as Christian and Jewish Platonists writing in Greek attest and of course as...

Climate Liberalism examines the potential and limitations of classical-liberal approaches to pollution control and climate change. Some successful environmental strategies, such as the use of catch-shares for fisheries, instream water rights, and tradable emission permits, draw heavily upon the classical liberal intellectual tradition and its emphasis on property rights and competitive markets. This intellectual tradition has been less helpful, to date, in the development or design of climate change policies. Climate Liberalism aims to help fill the gap in (...) the academic literature examining the extent to which classical-liberal principles, including an emphasis on property rights, decentralized authority and dynamic markets, can inform the debate over climate-change policies. The contributors in this book approach the topic from a range of perspectives and represent multiple academic disciplines. Chapters consider the role of property rights and common-law legal systems in controlling pollution, the extent to which competitive markets backed by legal rules encourage risk minimization and adaptation, and how to identify the sorts of policy interventions that may help address climate change in ways that are consistent with liberal values.

What Robots Can and Can't Be (hereinafter Robots) is, as Selmer Bringsjord says "intended to be a collection of formal-arguments-that-border-on-proofs for the proposition that in all worlds, at all times, machines can't be minds" (Bringsjord, forthcoming). In his (1994) "Précis of What Robots Can and Can't Be" Bringsjord styles certain of these arguments as proceeding "repeatedly . . . through instantiations of" the "simple schema".

If scientists rely on assumptions rather than logic, empirical confirmation, and falsification, they are no longer doing science but ideology – which is, by definition, unethical. As a recent US National Academy of Sciences report put it, “bad science is always unethical.”1 This article discusses several ways in which toxicologists can fall into ideology – bad, therefore unethical, science. In part because of the increasing expense of pollution control, some toxicologists have been reexamining pollution dose-response curves that (...) are non-monotonic, that is, curves in which the direction of some response changes with increasing or decreasing dose.2 Ethanol is a classic example of a non-monotonic dose-response curve because moderate drinking is associated with lower risks of heart disease, whereas heavy drinking is associated with higher risks.3,4 If some low-dose pollutants exhibit adaptive or “beneficial effects,”5 this might suggest re-thinking pollution regulations which presuppose linear no-threshold (LNT) dose-response curves.

Designing and manufacturing medical devices for specific patients is becoming increasingly feasible with developments in 3D printing and 3D imaging software. This raises the question of how patient-specific devices can be evaluated, since our ‘gold standard’ method for evaluation, the randomised controlled trial, requires that an intervention is standardised across a number of individuals in an experimental group. I distinguish several senses of patient-specific device, and focus the discussion on understanding the problem of variations between instances of an (...) intervention for RCT evaluation. I argue that, despite initial appearances, it is theoretically possible to use RCTs to evaluate some patient-specific medical devices. However, the argument reveals significant difficulties for ensuring the validity of such trials, with implications for how we should think about methods of evidence gathering and regulatory approaches for these technologies.

In business and government, databases contain large quantities of digital transactional data (purchases made, services used, finances transferred, benefits received, licences acquired, borders crossed, tickets purchased). The data can be understood as ongoing and dynamic measurements of the activities and doings of people. In government, numerous database devices have been developed to connect such data across services to discover patterns and identify and evaluate the performance of individuals and populations. Under the UK’s New Labour government, the development of such (...) devices was part of a broader policy known as ‘joined-up thinking and government’. Analyses of this policy have typically understood joining up as an operation of adding together distributed data about subjects, which can then be used in the service of government surveillance, the database state or informational capitalism. But rather than such technical or managerialist analytics, I argue that topological analytics capture what these database devices enact and do: they materialize the ‘individuality’ of subjects in intensified, distributed and fluctuating ways and materialize and intensify a logic of what Deleuze describes as modulating controls. Through examples of UK New Labour social policy initiatives over the past decade, I argue that topological analytics can account for these as immanent rather than exceptional properties of database devices and, as such, part and parcel of a governmental logic and ontology of subjects.

In the early 1970s, the idea of precaution—of heeding rather than ignoring scientific evidence of harm when there is uncertainty, and taking action that errs on the side of safety—was so appealing that the US Congress used it as the basis of the toxics provisions of the Clean Water Act of 1972, the federal Environmental Protection Agency based its proposals for implementing those provisions on it, and the courts frequently tended toward it when resolving conflicts over the implementation of (...) class='Hi'>pollution control law. In other words, precaution was written into toxic water pollutant control law and was beginning to be written into policy and regulations. By 1976, the tables were completely turned. The EPA abandoned the safety-providing approach in the implementation of the law, even though the law required it, and adopted a risk-taking approach in the creation of standards for the vast majority of toxic water pollutants. The article examines how this change was brought about. It builds on recent work on undone science as an obstacle to regulation and contributes to the development of an account of the creation of the regulatory system, with both its achievements and its limitations.

This paper examines two parallel discussions of scientific modeling which have invoked experimentation in addressing the role of models in scientific inquiry. One side discusses the experimental character of models, whereas the other focuses on their exploratory uses. Although both relate modeling to experimentation, they do so differently. The former has considered the similarities and differences between models and experiments, addressing, in particular, the epistemic value of materiality. By contrast, the focus on exploratory modeling has highlighted the various kinds of (...) exploratory functions of models in the early stages of inquiry. These two perspectives on modeling are discussed through a case study in the field of synthetic biology. The research practice in question explores biological control by making use of an ensemble of different epistemic means: mathematical models and simulations, synthetic genetic circuits and intracellular measuring devices, and finally electronic circuits. We argue that the study of exploratory modeling should trace the ways different epistemic means, in different materialities, are being combined over time. Finally, the epistemic status of such novel investigative objects as synthetic genetic circuits is evaluated, with the conclusion that they can function as both experiments and models. (shrink)

Technological innovation has an important impact on environmental pollution. In this paper, first, we analyze the influence mechanism of technological innovation on environmental pollution and then design the index system of technological innovation. Then, we use the entropy method to calculate the technological innovation level of different regions in China based on provincial panel data from 2004 to 2016. Finally, the panel vector autoregression model is adopted, and taking the discharge of sewage, solid waste, and exhaust gas as (...) the research objects, the impact of technological innovation on them is empirically analyzed. The results show that China’s technological innovation level is steadily improving, but there are significant differences in the impact of technological innovation on wastewater, waste gas, and solid waste. Specifically, technological innovation can contribute to an increase in wastewater and solid waste emissions. However, the impact of this technological innovation on them is not equal. Secondly, the impact of technological innovation on exhaust emissions is to inhibit exhaust emissions in the short term and promote exhaust emissions in the long term. Finally, there are clear differences between them in terms of the specific impact of changes in wastewater, solid waste, and exhaust emissions. Changes in wastewater discharges and solid waste generation are largely derived from their own effects, while the role of technological innovation is supportive and insignificant. The change in exhaust emissions is initially influenced by itself, but in the long run, the influence of technological innovation gradually increases and eventually exceeds its own influence. Based on these research results, this paper puts forward corresponding policy suggestions to speed up environmental pollution control. (shrink)

The Internet of Things is an emerging information industry. Applying the information collection, transmission, and processing technologies in the Internet of Things technology to environmental monitoring, environmental emergency, and other environmental protection supervision fields will greatly improve the speed and accuracy of environmental supervision and facilitate the scientific development of environmental protection. Through the Internet of Things, people can obtain a large amount of reliable real-time information, and it is not easy to be affected by time, place, and environment, while (...) the wireless sensor network has the advantages of easy installation and low cost, so environmental monitoring through the Internet of Things is the future development trend. In this paper, in view of the current situation of water scarcity and serious water pollution in China, combined with the development trend and advantages of the Internet of Things, and based on the inadequacy of the existing microbial sensor data collection equipment, we propose a design scheme of microbial concentration monitoring system for waters based on IoT. The system is based on Zig Bee wireless sensor network to build a common data acquisition platform and design special hardware to carry out high-precision microbial sensor data acquisition in water and through the PC to complete the real-time measurement data storage, waveform display, and data processing. In this paper, the schematic diagram and PCB board design of the system hardware module NUC120 main control board, CC2530 RF board, Wi-Fi wireless communication module, and high-precision ADC acquisition module are completed and fabricated. Then, the four modules are combined to realize the development of the data aggregation node and data acquisition node of the dedicated Zig Bee wireless network hardware device. (shrink)

The present study investigated the impacts of mobile assisted vocabulary learning via digital flashcards. The data were collected from 44 adult English as Foreign Language learners in three intact classes in a private language teaching institute in Iran, randomly assigned to experimental and control learning conditions. The experimental group used a freely available DF application to learn items from a recently developed corpus-based word list for high-frequency vocabulary in English. The treatment was implemented as out-of-the-classroom learning activities where the (...) EFL learners used DFs to augment their vocabulary knowledge, and their learning gains were compared to the control group that received regular English language education. The participants’ vocabulary knowledge was tested in pre-, post-, and delayed post-tests, and the findings indicated that using DFs for outside the classroom vocabulary learning contributed significantly to short- and long-term improvements in the knowledge of high-frequency words. The study provided empirical evidence for the affordances of mobile assisted vocabulary learning for learning a considerable proportion of core vocabulary and has some implications for addressing the vocabulary learning needs of EFL learners.

Today, one out of every six children suffers from some form of neurodevelopmental abnormality. The causes are mostly unknown. Some environmental chemicals are known to cause brain damage and many more are suspected of it, but few have been tested for such effects. Philippe Grandjean provides an authoritative and engaging analysis of how environmental hazards can damage brain development and what we can do about it. The brain's development is uniquely sensitive to toxic chemicals, and even small deficits may negatively (...) impact our academic achievements, economic success, risk of delinquency, and quality of life. Chemicals such as mercury, polychlorinated biphenyls, arsenic, and certain pesticides pose an insidious threat to the development of the next generation's brains. When chemicals in the environment affect the development of a child's brain, he or she is at risk for mental retardation, cerebral palsy, autism, ADHD, and a range of learning disabilities and other deficits that will remain for a lifetime.We can halt chemical brain drain and protect the next generation, however, and Grandjean tells us how. First, we need to control all of the 200 industrial chemicals that have already been proven to affect brain functions in adults, as their effects on the developing brain are likely even worse. We must also push for routine testing for brain toxicity, stricter regulation of chemical emissions, and more required disclosure on the part of industries who unleash hazardous chemicals into products and the environment. Decisions can still be made to protect the brains of future generations."In his crisply written, deeply documented book, Dr. Philippe Grandjean, renowned physician and public health specialist, describes the exquisite vulnerability of the developing human brain to toxic chemicals in the environment, a vulnerability that he ascribes to the brain's almost unimaginable complexity. Today, nearly one in 6 children is born with a neurodevelopmental disorder - a birth defect of the brain. One in 8 has attention deficit disorder. One in 68 is diagnosed with autism spectrum disorder. These rates are far higher than those of a generation ago, and, although they are less publicized, the problems are more prevalent than those caused by thalidomide in the 1960's. The increases are far too rapid to be genetic. They cannot be explained by better diagnosis. How then could they have come to be? Dr. Grandjean has a diagnosis -- the thousands of toxic chemicals that have been released to the environment in the past 40 years with no testing for toxicity. David P. Rall, former Director of the US National Institute of Environmental Health Sciences, once stated that 'If thalidomide had caused a ten-point loss of IQ rather than obvious birth defects of the limbs, it would probably still be on the market'.

Today, one out of every six children suffers from some form of neurodevelopmental abnormality. The causes are mostly unknown. Some environmental chemicals are known to cause brain damage and many more are suspected of it, but few have been tested for such effects. Philippe Grandjean provides an authoritative and engaging analysis of how environmental hazards can damage brain development and what we can do about it. The brain's development is uniquely sensitive to toxic chemicals, and even small deficits may negatively (...) impact our academic achievements, economic success, risk of delinquency, and quality of life. Chemicals such as mercury, polychlorinated biphenyls, arsenic, and certain pesticides pose an insidious threat to the development of the next generation's brains. When chemicals in the environment affect the development of a child's brain, he or she is at risk for mental retardation, cerebral palsy, autism, ADHD, and a range of learning disabilities and other deficits that will remain for a lifetime.We can halt chemical brain drain and protect the next generation, however, and Grandjean tells us how. First, we need to control all of the 200 industrial chemicals that have already been proven to affect brain functions in adults, as their effects on the developing brain are likely even worse. We must also push for routine testing for brain toxicity, stricter regulation of chemical emissions, and more required disclosure on the part of industries who unleash hazardous chemicals into products and the environment. Decisions can still be made to protect the brains of future generations."In his crisply written, deeply documented book, Dr. Philippe Grandjean, renowned physician and public health specialist, describes the exquisite vulnerability of the developing human brain to toxic chemicals in the environment, a vulnerability that he ascribes to the brain's almost unimaginable complexity. Today, nearly one in 6 children is born with a neurodevelopmental disorder - a birth defect of the brain. One in 8 has attention deficit disorder. One in 68 is diagnosed with autism spectrum disorder. These rates are far higher than those of a generation ago, and, although they are less publicized, the problems are more prevalent than those caused by thalidomide in the 1960's. The increases are far too rapid to be genetic. They cannot be explained by better diagnosis. How then could they have come to be?

Closed Loop medical devices such as Closed Loop Deep Brain Stimulation and Brain Computer Interface are some of the emerging neurotechnologies. New generations of implantable brain–computer interfaces have recently gained success in human clinical trials. These implants detect specific neuronal patterns and provide the subject with information to respond to these patterns. Further, Closed Loop brain devices give control to the subject so that he can respond and decide on a therapeutic goal. Although the implants have improved (...) subjects’ quality of life, their use has raised varied ethical concerns. The aim of this study is to provide an overview of the ethical implications specific to the therapeutic goals of closed loop brain implants. The authors analyze the related work qualitatively and quantitatively so as to help readers in understanding the various ethical implications of closed loop brain implants. (shrink)

Previous writers have examined how topic and disagreement in assessments are managed within everyday conversation. This work, however, has focused on two-party interaction and little research has examined these issues in the context of multi-party discussion. In this article we examine these issues in the context of discussion by the admissions group of an arts and crafts guild. Analysis of the group’s discussions shows that on occasion group members find themselves in outright disagreement in assessment which leads to what is (...) here described as ‘gainsaying’. However, a number of other instances reveal that the group is able to avoid problematic conversational structures of this sort by deploying a variety of topic control devices: insertion of collusive laughter, conversation restart and topic flow manoeuvres. The article concludes by drawing out some analytic distinctions between two-party and multi-party interactions. (shrink)

This book examines how regulatory and liability mechanisms have impacted upon product safety decisions in the pharmaceutical and medical devices sectors in Europe, the USA and beyond since the 1950s. Thirty-five case studies illustrate the interplay between the regulatory regimes and litigation. Observations from medical practice have been the overwhelming means of identifying post-marketing safety issues. Drug and device safety decisions have increasingly been taken by public regulators and companies within the framework of the comprehensive regulatory structure that has (...) developed since the 1960s. In general product liability cases have not identified or defined safety issues, and function merely as compensation mechanisms. This is unsurprising as the thresholds for these two systems differ considerably; regulatory action can be triggered by the possibility a product is harmful, whereas establishing liability in litigation requires proving that the product was actually harmful.As litigation normally post-dates regulatory implementation, the 'private enforcement' of public law has generally not occurred in these sectors. This has profound implications for the design of sectoral regulatory and liability regimes, including associated features such as extended liability law, class actions and contingency fees. This book forms a major contribution to the academic debate on the comparative utility of regulatory and liability systems, on public versus private enforcement, and on mechanisms of behaviour control.

Test anxiety remains a challenge for students and has considerable physiological and psychological impacts. The routine practice of slow, Device-Guided Breathing is a major component of behavioral treatments for anxiety conditions. This paper addresses the effectiveness of using DGB as a self-treatment clinical tool for test anxiety reduction. This pilot study sample included 21 healthy men and women, all college students, between the ages of 20 and 30. Participants were randomly assigned to two groups: DGB practice and wait-list control. (...) At the beginning and the end of 3-weeks DGB training, participants underwent a stress test, followed by measures of blood pressure and reported anxiety. Anxiety reduction in the DGB group as compared to controls was not statistically significant, but showed a large effect size. Accordingly, the clinical outcomes suggested that daily practice of DGB may lead to reduced anxiety. We assume that such reduction may lead to improved test performance. Our results suggest an alternative treatment for test anxiety that may also be relevant for general anxiety, which is likely to increase due to the ongoing COVID-19 pandemic. (shrink)

Increasing ethical attention and debate is focusing on whether individuals who take part in clinical trials should be given access to post-trial care. However, the main focus of this debate has been upon drug trials undertaken in low-income settings. To broaden this debate, we report findings from interviews with individuals (n = 24) who participated in a clinical trial of a closed-loop system, which is a medical device under development for people with type 1 diabetes that automatically adjusts blood glucose (...) to help keep it within clinically recommended ranges. Individuals were recruited from UK sites and interviewed following trial close-out, at which point the closed-loop had been withdrawn. While individuals were stoical and accepting of the requirement to return the closed-loop, they also conveyed varying degrees of distress. Many described having relaxed diabetes management practices while using the closed-loop and having become deskilled as a consequence, which made reverting back to pre-trial regimens challenging. Participants also described unanticipated consequences arising from using a closed-loop. As well as deskilling, these included experiencing psychological and emotional benefits that could not be sustained after the closed-loop had been withdrawn and participants reevaluating their pre- and post-trial life in light of having used a closed-loop and now perceiving this life much more negatively. Participants also voiced frustrations about experiencing better blood glucose control using a closed-loop and then having to revert to using what they now saw as antiquated and imprecise self-management tools. We use these findings to argue that ethical debates about post-trial provisioning need to be broadened to consider potential psychological and emotional harms, and not just clinical harms, that may result from withdrawal of investigated treatments. We also suggest that individuals may benefit from information about potential nonclinical harms to help make informed decisions about trial participation. (shrink)

The last decade has witnessed the mass distribution and adoption of smart home systems and devices powered by artificial intelligence systems ranging from household appliances like fridges and toasters to more background systems such as air and water quality controllers. The pervasiveness of these sociotechnical systems makes analyzing their ethical implications necessary during the design phases of these devices to ensure not only sociotechnical resilience, but to design them for human values in mind and thus preserve meaningful human (...) control over them. This paper engages in a conceptual investigations of how meaningful human control over smart home devices can be attained through design. The value sensitive design (VSD) approach is proposed as a way of attaining this level of control. In the proposed framework, values are identified and defined, stakeholder groups are investigated and brought into the design process and the technical constraints of the technologies in question are considered. The paper concludes with some initial examples that illustrate a more adoptable way forward for both ethicists and engineers of smart home devices. (shrink)

A novel fuzzy control scheme with adaptation algorithms is developed for robot manipulators’ system. At the beginning, one adjustable parameter is introduced in the fuzzy logic system, the robot manipulators system with uncertain nonlinear terms as the master device and a reference model dynamic system as the slave robot system. To overcome the limitations such as online learning computation burden and logic structure in conventional fuzzy logic systems, a parameter should be used in fuzzy logic system, which composes fuzzy (...) logic system with updated parameter laws, and can be formed for a new fashioned adaptation algorithms controller. The error closed-loop dynamical system can be stabilized based on Lyapunov analysis, the number of online learning computation burdens can be reduced greatly, and the different kinds of fuzzy logic systems with fuzzy rules or without any fuzzy rules are also suited. Finally, effectiveness of the proposed approach has been shown in simulation example. (shrink)

Over recent years, brain-computer interface (BCI) has emerged as an alternative communication system between the human brain and an output device. Deciphered intents, after detecting electrical signals from the human scalp, are translated into control commands used to operate external devices, computer displays and virtual objects in the real-time. BCI provides an augmentative communication by creating a muscle-free channel between the brain and the output devices, primarily for subjects having neuromotor disorders, or trauma to nervous system, notably (...) spinal cord injuries (SCI), and subjects with unaffected sensorimotor functions but disarticulated or amputated residual limbs. This review identifies the potentials of electroencephalography (EEG) based BCI applications for locomotion and mobility rehabilitation. Patients could benefit from its advancements such as wearable lower-limb (LL) exoskeletons, orthosis, prosthesis, wheelchairs, and assistive-robot devices. The EEG communication signals employed by the aforementioned applications that also provide feasibility for future development in the field are sensorimotor rhythms (SMR), event-related potentials (ERP) and visual evoked potentials (VEP). The review is an effort to progress the development of user’s mental task related to LL for BCI reliability and confidence measures. As a novel contribution, the reviewed BCI control paradigms for wearable LL and assistive-robots are presented by a general control framework fitting in hierarchical layers. It reflects informatic interactions, between the user, the BCI operator, the shared controller, the robotic device and the environment. Each sub layer of the BCI operator is discussed in detail, highlighting the feature extraction, classification and execution methods employed by the various systems. All applications’ key features and their interaction with the environment are reviewed for the EEG-based activity mode recognition, and presented in form of a table. It is suggested to structure EEG-BCI controlled LL assistive devices within the presented framework, for future generation of intent-basedmultifunctional controllers. Despite the development of controllers, for BCI-based wearable or assistive devices that can seamlessly integrate user intent, practical challenges associated with such systems exist and have been discerned, which can be constructive for future developments in the field.
