There is considered the calculation of the average value of the overall heat-transfer coefficient for counterflow between parallel plates or in concentric tubes when the flows are laminar and the thermal entry lengths for one or both streams extend over a significant part of the exchanger length. It is shown that if this length is at least less than the total length for one of the fluids, the average value of the overall coefficient can be calculated with adequate accuracy from the average values of the individual coefficients by means of the usual definition of the overall coefficient. When both thermal entry lengths exceed the exchanger length, then a special calculation is needed to obtain suitable average overall values. This result is given in graphical form and supported by more exact results from the literature and as obtained here.

This study reports the quantification and analysis of the ecosystem services (ESs) value of Posidonia oceanica (L.) Delile (1813) meadows in Italy (Liguria, Tuscany, Latium, Campania, Calabria, Apulia, Sardinia, and Sicily regions). The ES evaluation method of P. oceanica meadows applied in this study was obtained from a previous study in which the site-specific approach for the definition of the benefits and services was applied. The distribution of P. oceanica and the ESs economic value have been managed through an open-source geographic information system (QGIS), focusing on five essential ESs: carbon sequestration, bioremediation, oxygen production, erosion protection, and food production. The average value of the ESs obtained on the Italian national scale is €21,660.5 ha−1 yr−1, which is comparable with the values reported in the international literature concerning P. oceanica ESs. The results of this study confirm that the economic evaluation of ESs is an essential tool for the management of the coastal marine environment, especially considering the modularity of the applied approach. The value of the total benefits, considering the entire extension of the national P. oceanica meadows, represents significant value with respect to the Italian gross domestic product, and the individual budgets of the considered Italian regions.

A wave theory treatment is given of the reflection of elastic wave pulses from plane parallel plates. The analysis automatically resolves the reflected wave system into a series of undistorted individual pulses having the same shape as that impinging on the reflecting plate, but which are characterized by varying amplitudes and phase shifts corresponding to various internal reflection and refraction processes within the plate. The numerical values for the reflection coefficients for the three most prominent longitudinal reflected pulses resulting from an incident longitudinal wave pulse are given in both tabular and graphical form, for angles of incidence between 0 and 30°, for velocity ratios between the plate and incident medium of 1.0 to 2.0, and for density ratios of 0.9 to 1.3. The actual superposition of the individual reflected waves is shown graphically for three cases where the ratio of the reflecting plate thickness to the length of the incident pulse has the values 2, 1, or 1/2.

Why does writing of the death penalty demand the first-person treatment that it also excludes? The article investigates the role played by the autobiographical subject in Derrida's The Death Penalty, Volume I, where the confessing ‘I’ doubly supplements the philosophical investigation into what Derrida sees as a trend toward the worldwide abolition of the death penalty: first, to bring out the harmonies or discrepancies between the individual subject's beliefs, anxieties, desires and interests with respect to the death penalty and the state's exercise of its sovereignty in applying it; and second, to provide a new definition of the subject as haunted, as one that has been, but is no longer, subject to the death penalty, in the light of the worldwide abolition currently underway.

The problem of identity is an issue of contemporary society that is not only expressed in daily life concerns but also in discourses of politics and social movements. Nevertheless, the I and the needs of self-fulfillment usually are taken for granted. This paper offers thoughts regarding individual identity based on Niklas Luhmann’s systems theory. From this perspective, identity is not observed as a thing or as a subject, but rather as a “selfillusion” of a system of consciousness, which differentiates itself from the world, event after event, in a contingent way. As concerns the definition  of contents of self-identity, the structures of social systems define who is a person, how he or she should act, and how much esteem he or she should receive. These structures are adopted by consciousness as its own identity structures; however, some social contexts are more relevant for self-identity construction than others. Moral communication increases the probability that structure appropriation takes place, since the emotional element of identity is linked to the esteem/misesteem received by the individual from the interactions in which he or she participates.

In this paper, the author examines public service as depicted in the television series Buffy the Vampire Slayer (BtVS). First, she shows how slaying meets the economist’s definition of a public good, using the BtVS episode “Flooded” (6.04). Second, she discusses public service motivation (PSM) to determine whether or not Buffy, a public servant, operates from a public service ethic. Relying on established measures and evidence from shooting scripts and episode transcripts, the author concludes Buffy is a public servant motivated by a public service ethic. In this way, BtVS informs scholarship on public service by broadening the concept of PSM beyond the public sector; prompting one to wonder whether it is located in a sector, an occupation, or in the individual. These conclusions allow the author to situate Buffy alongside other idealized public servants in American popular culture.

This chapter discusses the implications of Spinoza’s concept of individual bodies, as introduced in the definition of individuum in the physical digression. It begins by showing that this definition allows for an extremely wide application of the term; accordingly, very different sorts of physical entities can be described as Spinozistic individuals. Given the quite distinct use of the terms divisibilis and indivisibilis in his metaphysics, however, the chapter argues that the physical concept of individuality is not universally applied in the Ethics but reserved for physical or natural-philosophical considerations. The chapter concludes with a discussion of the problem of collective individuals. It is argued that, while societies or states are described as individual bodies, they do not constitute individual group minds in the strict sense of the term for Spinoza. This in turn indicates that minds are not individuated in the same way as bodies.

Nationwide Register Study

AbstractThe aim of this study was to examine the validity of the Gender Dysphoria (GD) diagnoses in the Swedish National Patient Register (NPR), to discuss different register-based definitions of GD and to investigate incidence trends. We collected data on all individuals with registered GD diagnoses between 2001 and 2016 as well as data on the coverage in the NPR. We regarded gender confirming medical intervention (GCMI) as one proxy for a clinically valid diagnosis and calculated the positive predictive value (PPV) for receiving GCMI for increasing number of registered GD diagnoses. We assessed crude and coverage-adjusted time trends of GD during 2004–2015 with a Poisson regression, using assigned sex and age as interaction terms. The PPV for receiving GCMI was 68% for ≥ 1 and 79% for ≥ 4 GD-diagnoses. The incidence of GD was on average 35% higher with the definition of ≥ 1 compared to the definition of ≥ 4 diagnoses. The incidence of GD, defined as ≥ 4 diagnoses increased significantly during the study period and mostly in the age categories 10–17 and 18–30 years, even after adjusting for register coverage. We concluded that the validity of a single ICD code denoting clinical GD in the Swedish NPR can be questioned. For future research, we propose to carefully weight the advantages and disadvantages of different register-based definitions according to the individual study’s needs, the time periods involved and the age-groups under study.

Abstract Background Previous research has indicated that migrants risk facing inequities both internationally and in Sweden; integration policies are therefore important to study. How health is described in policies affects how health interventions are approached. A discourse analysis offers a way of understanding how health is framed within the integration policies of the Establishment Program. The aim was to critically analyse the health discourses used in Swedish and European Union (EU) integration policies. Methods A critical discourse analysis, inspired by Fairclough, was performed on integration policies related to Sweden, on local, regional, national and the EU level. The policies of the Establishment Program, which focuses on newly arrived migrants (refugees, persons of subsidiary protection and their relatives who arrived through family reunification), were chosen for the analysis, and 17 documents were analysed in total. Results The analysis of the documents showed that although no definition of health was presented, health discourses were expressed in the form of the medicalization of health and the individualization of health. This not only by the terminology used, but also in how the healthcare sector was considered responsible for any health related issue and how individual health behaviours were of focus in interventions to promote health. Conclusions A pathogenic approach to health was visible in the policies and individual disease prevention was the main health focus. The results showed similarities to previous research highlighting how a particular understanding of health in a neoliberal context is formed. Key messages Health as a resource is missing in the integration policy documents. Viewing health as an individual quality puts the responsibility of promoting health on the individual.

Abstract Art and Value: Art’s Economic Exceptionalism in Classical, Neoclassical and Marxist Economics reveals the irreconcilable differences between the Marxist economic definition of the term ‘value’ and its other uses in relation to the art object. It corrects the faulty assumption, symptomatic of a capitalist worldview, that rare or historic objects bear intrinsic value. Beech’s analysis of art’s value-form is critical to unpacking the double ontological condition of art as both an object of collective symbolic value and as a hoard of monetary value, since the two operate in mutually exclusive spheres, yet function to constitute one another. The book can help us understand the capitalist sleight of hand that allows art to flicker between two forms of being, making profit appear as value, and value appear as significance (and vice versa), the toggling between the two facilitating the transfer of commonly-held symbolic value in support of the individual accumulation of wealth.
