This book reminds readers of the insatiable attraction of the “blue highway”—“But in those brevities just before dawn and a little after dusk—times neither day or night—the old roads return to the sky some of its color.

The term ‘heat’ originates from the Old English word hǣtu, a word of Germanic origin; related to the Dutch ‘hitte’ and German ‘Hitze’. Today, we distinguish three different meanings of the word ‘heat’. First, ‘heat’ is understood in colloquial English as ‘hotness’. There are, in addition, two scientific meanings of ‘heat’. ‘Heat’ can have the meaning of the portion of energy that changes with a change of temperature. And finally, ‘heat’ can have the meaning (...) of the transfer of thermal energy from a hotter to a colder system or body. By contrast, for the Ancients and Scholastics, ‘heat’ was a manifest, real quality of bodies and there was an ontological distinction between biological or innate heat (which was regarded as an innate principle of life for warm-blooded animals) and the physical manifest heat of external objects, which is potentially harmful. During the late Renaissance period, however, both views changed fundamentally and evolved - via the application of physical and mechanical analogies - into the foundations for today’s unified mechanistic theory of heat.

More Heat Than Light is a history of how physics has drawn some inspiration from economics and also how economics has sought to emulate physics, especially with regard to the theory of value. It traces the development of the energy concept in Western physics and its subsequent effect upon the invention and promulgation of neoclassical economics. Any discussion of the standing of economics as a science must include the historical symbiosis between the two disciplines. Starting with the philosopher Emile (...) Meyerson's discussion of the relationship between notions of invariance and causality in the history of science, the book surveys the history of conservation principles in the Western discussion of motion. Recourse to the metaphors of the economy are frequent in physics, and the concepts of value, motion, and body reinforced each other throughout the development of both disciplines, especially with regard to practices of mathematical formalisation. However, in economics subsequent misuse of conservation principles led to serious blunders in the mathematical formalisation of economic theory. The book attempts to provide the reader with sufficient background in the history of physics in order to appreciate its theses. The discussion is technically detailed and complex, and familiarity with calculus is required. (shrink)

The conceptualization of the vital force of living beings as a kind of breath and heat is at least as old as Homer. The assumptions that life and living things were somehow causally related to 'heat' and 'breath' would go on to inform much of ancient medicine and philosophy. This is the first volume to consider the relationship of the notions of heat, breath, and soul in ancient Greek philosophy and science from the Presocratics to Aristotle. Bringing (...) together specialists both on early Greek philosophy and on Aristotle, it brings an approach drawn from the history of science to the study of both fields. The chapters give fresh and detailed interpretations of the theory of soul in Heraclitus, Empedocles, Parmenides, Diogenes of Appolonia, and Democritus, as well as in the Hippocratic Corpus, Plato's Timaeus, and various works of Aristotle.

Climate has a strong influence on urban planning and also plays a fundamental role in soil composition affecting the character of plants and animals. The climate is a combination of different meteorological factors that characterized a specific region over a specific time. The movement of the Sun and Earth inclination toward it is the most important factors which determine the characteristics of the climate. The global movement of the air from equator toward poles and vice versa influences also drastically the (...) climate change. In this section are also included breezes. Also air relative humidity plays an important role shaping the climate. It plays a very important role in cloud formation. The built environment can influence the urban climate of the city through height, form, and applied building materials. Building form and shape, building materials, openings in the façade, and their orientation often are determined by climate parameters. Urban density, directions, and street network and their shape are related to the climate change, apart from topography. Density of urban structures produces important effects on the microclimatic conditions in external spaces. The bioclimatic behavior of each type of outdoor spaces depends on the relationship with its surrounding elements. The city of Tirana is included in Mediterranean climate characterized by hot dry summers and mild cold wet winters with high daily thermal excursions. All of the countries bordering the Mediterranean Sea benefit from the Mediterranean climate. Specifically spotted, Tirana is part of Mediterranean coastal zone (<22 °C in temperature) with an annual temperature of 15.3 °C. In the inner city can be found areas with high pollution, which normally contain a high percentage of business and industry, settlements, and traffic, so-called “sealed” areas. They constitute “hyperthermic areas” or “heat islands”. The term “heat island” describes built-up areas which are hotter than nearby rural areas. Heat islands can affect communities by increasing summertime peak energy demand, air-conditioning costs, air pollution, greenhouse gas emissions, heat-related illness and mortality, and water quality. The aim of the bioclimatic design is also the reduction of the heat-island phenomenon. The use of materials with different energy absorption capabilities and integration of green spaces into urban life is important. The vegetation effects on microclimate and in the built environment are present. Trees are necessary and indispensable to human life. They provide shelter for us, provide food, and their fibers cloth us. Implementation of the green belts in the city is one of the strategies in order to reduce heat-island effect. Vegetation also can provide a deep feeling of attachment to certain places and trees which are part of it. The use of trees avoids monotony and ensures diversification. They play a crucial role creating microclimates which influence the thermal comfort of people reducing heating or cooling loads. Vegetation also creates cooler microclimates around the building through evapotranspiration, reduces wind speed, regulates humidity, and reduces temperature. It is observed that tree species have a greater influence on humidity than on temperature. Trees can also absorb and reduce the reverberation time of the sound, behaving as sound buffers. The benefits of tree plantation in the inner city are enormous and they can’t be neglected. (shrink)

In American Heat, Donald Brown critically analyzes the U.S. response to global warming, inviting readers to examine the implicit morality of the U.S position, and ultimately to help lead the world toward an equitable sharing of the burdens and benefits of protecting the global environment. In short, Brown argues that an ethical focus on global environmental matters is the key to achieving a globally acceptable solution.

Cities and towns are expanding and thriving as a result of urbanization, which also significantly changes the local climate. One of the most significant phenomena associated with urbanization is the Urban Heat Island (UHI) effect. This phenomenon is increasingly being studied worldwide. The paper aims to investigate the UHI phenomenon in the metropolitan area of Tirana, Albania. It analyses the impact of the UHI on four specific locations in Tirana, its causes and mitigation measures, as well as variations in (...) surface temperature, CO2 emissions, and relative humidity. The regions are measured and observed using a specific instrument such as the Testo 435. Considering the mean surface temperature variations between urban and rural regions ranging from 28.4°C to 33.7 °C, CO2 emissions from 302.9 ppm to 416.2 ppm, and relative humidity from 34.1% to 41.2%, it is found that the UHI impact in Tirana is significant. The lack of green spaces, high building density, urban patterns, building materials used, transport, and energy use are the main contributors to the UHI in central Tirana. Increasing green spaces, using reflective materials, and promoting sustainable urban design are some of the mitigation techniques suggested to reduce the UHI effect in Tirana. (shrink)

Originally published in 1936 as the second instalment of McKenzie's School Certificate series, this book explains the physical properties of heat. The text is accompanied by multiple photographs, drawings and diagrams to illustrate key points, and every chapter concludes with several questions for students to reinforce the chapter content. This book will be of value to anyone with an interest in the history of science education in Britain.

We consider work extraction from two finite reservoirs with constant heat capacity, when the thermodynamic coordinates of the process are not fully specified, i.e., are described by probabilities only. Incomplete information refers to both the specific value of the temperature as well as the label of the reservoir to which it is assigned. Based on the concept of inference, we characterize the reduced performance resulting from this lack of control. Indeed, the estimates for the average efficiency reveal that uncertainty (...) regarding the exact labels reduces the maximal expected efficiency below the Carnot value ), its minimum value reproducing the well known Curzon–Ahlborn value: \ . We also estimate the efficiency before the value of the temperature is revealed. It is found that if the labels are known with certainty, then in the near-equilibrium limit the efficiency scales as \ , while if there is maximal uncertainty in the labels, then the average estimate for efficiency drops to \ . We also suggest how the inferred properties of the incomplete model can be mapped onto a model with complete information but with an additional source of thermodynamic irreversibility. (shrink)

Ever since climate change has been identified as one of the most significant challenges of humanity, climate change deniers have repeatedly tried to discredit the work of scientists. To show how these processes work, Maria M. Sojka examines three ideals about how science should operate. These ideals concern the understanding of uncertainties, the relationship between models and data, and the role of values in science. Their widespread presence in the public understanding of science makes it easy for political and industrial (...) stakeholders to undermine inconvenient research. To address this issue, Sojka analyses the importance of tacit knowledge in scientific practice and the question of what defines an expert. (shrink)

Across Europe, countries are reducing CO2 emissions and energy demand by lowering the temperature in public office buildings. These measures affect men and women unequally because the latter prefer and, indeed, perform better under higher temperatures than the standard temperature. Lowering the temperature thus further increases an already existing inequality. We show that the philosophical literature on discrimination provides an interesting theoretical approach to understanding such measures. On prominent understandings of what discrimination is, the policy would be considered direct discrimination (...) against women if it could be shown to reflect a broader inattentiveness to the needs of women in society. Alternatively, and more straightforwardly, the policies can be considered indirect discrimination because of their disparate effects on men and women. The final part of the paper shows that the policies are also wrong for the reasons it is often argued that discrimination is wrong—to wit, that it harms or disrespects those who are discriminated against. The final section suggests a range of measures to offset the discriminatory aspects of the policy. (shrink)

ABSTRACT This article contrasts Francis Bacon’s understanding of civil war, sedition, and rebellion with that of his near contemporaries and predecessors, especially Montaigne, Bodin, Machiavelli, Alberico Gentili and Edward Forset. The article contends that for Bacon, civil war, sedition, and rebellion are the antitheses of good government and that which prudent policy aims to avoid. The article further argues that for Bacon as sedition and its extremities are caused by poverty and discontentment, and these, in Bacon’s view, are the result (...) of overpopulation or ‘surcharge of people’, Bacon’s view for the avoidance of civil war aims at policies of outward expansion in the form of colonies and wars of aggression, both of which aim to reduce the metropole’s own population and therewith its propensity to civil war. The article argues that a consideration of Bacon on civil war in particular will shed considerable light on the ideological origins of the British Empire which have often been ignored – where some contemporary political theorists and historians are keen to link ideologies of empire to corresponding positions in political anthropology. A consideration of Bacon’s thought on civil war will show, instead, the article contends, that for key ideological originators of imperial justifications, imperial projects have their origin in domestic politics and the avoidance of civil war.

The mitochondrion is known as the “powerhouse” of eukaryotic cells since it is the main site of adenosine 5′‐triphosphate (ATP) production. Using a temperature‐sensitive fluorescent probe, it has recently been suggested that the stray free energy, not captured into ATP, is potentially sufficient to sustain mitochondrial temperatures higher than the cellular environment, possibly reaching up to 50 °C. By 50 °C, some DNA and mitochondrial proteins may reach their melting temperatures; how then do these biomolecules maintain their structure and function? (...) Further, the production of reactive oxygen species (ROS) accelerates with temperature, implying higher oxidative stresses in the mitochondrion than generally appreciated. Herein, it is proposed that mitochondrial heat shock proteins (particularly Hsp70), in addition to their roles in protein transport and folding, protect mitochondrial proteins and DNA from thermal and ROS damage. Other thermoprotectant mechanisms are also discussed. (shrink)

Philosophical discussions regarding the status of emotion as a scientific domain usually get framed in terms of the question whether emotion is a natural kind. That approach to the issues is wrongheaded for two reasons. First, it has led to an intractable philosophical impasse that ultimately misconstrues the character of the relevant debate in emotion science. Second, and most important, it entirely ignores valence, a central feature of emotion experience, and probably the most promising criterion for demarcating emotion from cognition (...) and other related domains. An alternate philosophical hypothesis for addressing the issues is pro- posed. It is that emotion is a naturally occurring valenced phenomenon that is.. (shrink)

Over the years, the urban heat vulnerability has evolved as a pressing global concern for researchers and policymakers alike. Numerous studies have aimed at mitigating the adverse effects of urban heat vulnerability on public health and safety. However, the critical task of selecting the most fitting indicator for urban heat islands in public spaces is not emphasized in the existing studies, considering the diverse indices available. Beyond identification, studies that delve into the prioritization of these indices and (...) the determination of optimal variables along with their respective weights are scanty. The present study attempts to address these gaps in urban heat vulnerability research through the lens of natural solutions. The study employs a fuzzy analytical hierarchy approach to ascertain the weights of selected criteria, providing a nuanced understanding of the multifaceted factors influencing their applicability. Real-time impact estimation using the fuzzy technique for order of preference by similarity to ideal solutions enhances the practicality of the findings. The results reveal a set of pivotal characteristics crucial for constructing a robust heat vulnerability index, facilitating the prioritization of selected criteria. The implementation of this hybrid methodology culminates in a streamlined, precise, and practical tool for evaluating heat vulnerability in hot urban public spaces. These findings contribute valuable insights to the academic discourse and offer a tangible resource for policymakers and practitioners. The proactive approach provides a roadmap for addressing impending challenges related to urban heat vulnerability, marking a positive step toward creating resilient and sustainable urban environments.

The heat shock genes (hsp genes) are a family of truly ubiquitous genes which have been highly conserved throughout evolution. The protein products of these genes, the heat shock proteins (hsps) are thought to play a protective role in cells (although this may not be their only function). The genes and their products have been the subjects of intense research both at the cellular and molecular levels over the past few years. This review deals with the conservation of (...) the heat shock response and with the expression of the hsp genes under different conditions: they are usually activated as a group by different forms of stress, but can be expressed individually or in subsets at different stages during normal development and the expression of one of them is evoked by the products of different transforming genes. Experimental approaches which have provided information or which have led to hypotheses regarding the molecular details of the mechanisms regulating the expression of the genes are discussed.

The reduction of the concept of heat to that of molecular kinetic energy is recurrently presented as lending analogical support to the project of reduction of phenomenal concepts to physical concepts. The claimed analogy draws on the way the use of the concept of heat is attached to the experience in first person of a certain sensation. The reduction of this concept seems to prove the possibility to reduce discourse involving phenomenal concepts to a scientific description of neural (...) activity. But is this analogy really justified? We will show that if there is an analogy, far from speaking for a reduction of phenomenal concepts, it rather stresses the necessity to integrate phenomenal reports in the scientific study of experience.

This unfortunately titled volume offers a collection of fourteen essays and two introductions, many of which stem from a 2014 conference, Aristotle and His Predecessors on Heat, Pneuma, and Soul, which is a more honest reflection of the contents, given its exclusion of the Stoics. Of the essays, eight are devoted to Aristotle, four to Presocratic natural philosophy, one to Plato, and one to the De Spiritu. The poor titling and somewhat oddly circumscribed selection of who and what receives (...) attention, however, do not detract from the quality of the contributions themselves, which is largely excellent.One highlight is Simon Trépanier's account of soul in Empedocles, the...

Climate change has substantial impacts on public health and safety, disease risks and the provision of health care, with the poor being particularly disadvantaged. Management of the associated health risks and changing health service requirements requires adequate responses at local levels. Health-care providers are central to these responses. While climate change raises ethical questions about its causes, impacts and social justice, medicine and bioethics typically focus on individual patients and research participants rather than these broader issues. We broaden this focus (...) by examining awareness among health-care providers in the Caribbean region, where geographic and socioeconomic features pose particular vulnerabilities to climate change. In focus groups, Caribbean providers described rises in mosquito-borne, flood-related, heat-related, respiratory and mental illnesses, and attributed these to local impacts of climate change. Their discussions showed that the significance of these impacts differs in different Caribbean nations, raising policy and social justice questions. Bioethics and public health ethics are situated to frame, inform and initiate public and policy dialog about values and scientific evidence associated with climate change. We urge readers to initiate such dialog within their own institutions about the context-dependent nature of the burdens of climate change, and values and policies that permit it to worsen. (shrink)

An attempt is made to clarify a thought experiment introduced by P. T. Landsberg concerning the relativistic heat flow between bodies in relative motion. It is shown that if the problem is analyzed within the covariant thermodynamics developed by R. Balescu, supplemented by the second law of thermodynamics as proposed here, then such heat flow considerations do not fix the transformation of temperature as Landsberg contends. Instead, the transformation of temperature is left as being purely a matter of (...) definition. (shrink)

Background: Contact heat evoked potentials is used to diagnose small fiber neuropathy. We established the normal values of CHEPs parameters in Chinese adults, optimized the test technique, and determined its reproducibility.Methods: We recruited 151 healthy adults. CHEPs was performed on the right forearm to determine the optimal number of stimuli, and then conducted at different sites to establish normal values, determine the effects of demographic characteristics and baseline temperature, and assess the short- and long-term reproducibility. N2 latency/height varied with (...) age and sex, while P2 latency/height and N2–P2 amplitude varied with age. The optimal number of stimuli was three.Results: N2 latency/height and P2 latency/height decreased and N2–P2 amplitude and visual analog scale score increased with increased baseline temperature. CHEPs parameters did not differ with time.Conclusion: We established normal CHEPs values in Chinese adults. We found that CHEPs parameters changed with baseline temperature and that the short- and long-term test reproducibility were satisfactory. (shrink)

Fossil organisms offer our only direct insight into how the distinctive body plans of extant organisms were assembled. However, realizing the potential evolutionary significance of fossils can be hampered by controversy over their interpretation. Here, as a guide to evaluating palaeontological debates, we outline the process and pitfalls of fossil interpretation. The physical remains of controversial fossils should be reconstructed before interpreting homologies, and choice of interpretative model should be explicit and justified. Extinct taxa lack characters diagnostic of extant clades (...) because the characters had not yet evolved, because of secondary loss, or because they have rotted away. The latter, if not taken into account, will lead to the spurious assignment of fossils to basally branching clades. Conflicting interpretations of fossils can often be resolved by considering all the steps in the process of anatomical analysis and phylogenetic placement, although we must accept that some fossil organisms are simply too incompletely preserved for their evolutionary significance to be realized.

As part of current energy transitions in the Global North, households have begun adopting renewable energy technologies, such as heat pumps and solar power systems, in significant numbers. These changes give rise to the following question: how are technology and gender configured when new technologies enter everyday life? Based upon ethnographic fieldwork on interactions between households, technologies, and technicians and interviews with sales technicians, installers, and service mechanics, I demonstrate how both stable and fragile variants of renewable energy technologies (...) are enacted during prepurchase consultations and postpurchase installations, respectively. I employ science and technology studies scholarship, feminist ethics, and repair and maintenance studies—captured through the analytical lens of care—to analyze how technicians mobilize and tinker with gendered affection, knowledge, and action in households to effectuate adoption of renewable energy technologies. I clarify how, in this process, openings are created to configure both hegemonic and heterogeneous gender–technology relations. Finally, I advance discussion beyond gender issues by arguing that acknowledging the role of maintainability and the repair of user–technology relations in current energy transitions opens pathways not only for exploring gender in new and exciting ways in relation to technology but technician–user relationships as well.

In scientific realist eyes we are only warranted to assert that a theory is true or approximately true if that theory enjoys considerable explanatory and predictive success. The most well known challenge to this claim, the pessimistic meta-induction, holds that the history of science is replete with successful theories that are now considered false. In effect, this challenge raises doubts about the reliability of inferences from explanatory and predictive success to (approximate) truth. The main realist reaction has been to argue (...) that upon closer scrutiny the historical record can be reconciled with scientific realism. When a successful theory is abandoned, not all of its components are discarded but only those that are inessential or idle for the theory’s success. Their abandonment is thus inconsequential for the realist. In this talk I consider what the modern kinetic theory of heat managed to salvage from the outdated caloric theory and whether the inter-theoretic relations between the two theories support a realist view of science.

For countless citizens in the United States, guns are objects of personal attachment that provide strong feelings of power and security. I argue that a key reason for such tight affective bonds is that, under certain conditions, guns become integrated into their owners’ embodied experience. To flesh out this view, I explain (a) how firearms, as material artifacts, can become a part of the feeling body and (b) how this integration impacts one’s experience of self, others, and the world. I (...) first apply the distinction between body-incorporation and body-extension by De Preester and Tsakiris (Phenomenol Cogn Sci 8:307–319, 2009) to delineate how guns can (and cannot) be integrated into lived bodies. I then introduce Ihde's (Technology and the life world: from garden to earth, Indiana University Press, Bloomington, 1990) notion of embodiment relations to elaborate on the key experiential features of technologically extended bodies and complement the previous, sensorimotor-centric accounts of bodily extension with Colombetti's (Phenomenology for the twenty-first century, Palgrave Macmillan, London, 2016) concept of affective incorporation. With this theoretical framework in place, I proceed to examine the motives and affective dynamics involved in the incorporation of guns, the practices by which this incorporation is constituted, and its impact on gun carriers’ habitual comportment. In doing so, I identify two notable contradictions: first, between a desire for the power afforded by firearms and the lack in oneself that this power implies, and second, between one’s seemingly beneficial feelings of confidence/safety and potentially harmful transformations in one’s perceptions of threat. To conclude, I discuss how my analysis challenges current theorization on technologically extended bodies and consider its relevance for ongoing debates over gun policy. (shrink)

Not for the first time, the banks and other financial institutions have got themselves – and the rest of us – into a mess, this time on an unprecedented financial and geographical scale. It is no surprise that opinions about causes, consequences and cures abound with ethical issues, as well as technical and economic concerns, a focus of attention. It is to be hoped that useful lessons for the future will be learned. In this chapter, however, we step back from (...) a direct engagement with the stated ills of the financial system itself, whether actual or perceived, chronic or acute. Our starting point is that crisis in the financial system not only makes us stop and think; but it might also, particularly under conditions of moral panic, prevent us from thinking well. Our contention is that a further impediment to thinking well about financial crises is the lack of a substantial body of academic knowledge that might be termed ‘financial ethics’ – a corpus of well developed conceptual insights and appropriate empirical evidence. We identify some of the reasons for this situation and proffer some suggestions regarding what might be done to remedy it – including the development of knowledge that is as relevant to everyday practices during periods of normality as it is to providing perspectives on crisis. The chapter is structured as follows: the next section provides a perspective on debate during times of crisis; the middle section seeks to explain why academic financial ethics is not a significant constituent element of debate on the financial crisis post-2007; and the final two main sections explore ways in which an academic agenda for financial ethics might be constructed. In a curious way this chapter echoes some of the themes and especially the conclusion of David Bevan’s chapter in this work although the reasoning to the conclusion that finance ethics is an empty set follows a rather different Badiou-inspired path in chapter 18.

What can we hope to learn about brains from the free energy principle? In adopting the “primordial soup” physical model, Bruineberg et al. perpetuate the unsupported notion that the free-energy principle has a meaningful physical – and neuronal – interpretation. We examine how minimization of free energy arises in physical contexts, and what this can and cannot tell us about brains.
