Thermodynamic Equations

Ammonium salts represent a common problem for the refining industry. These saltslead to fouling of piping and heat exchangers resulting in loss of duty, underdeposit corrosionwhen wetted, and corrosive sour water solutionsonce sufficient water is available to dissociate these salts into solution. To properly manage fouling and corrosion associated with these salts, knowledge of the temperatures at which these salts will deposit is critical. In this age of process control, these temperatures can be predicted in real-time provided the salt deposition temperature relationships are known. The salt deposition equations for salts most often encountered in refining are not in the public domain. To close this gap, ammonium salt deposition equations were derived for NH4Cl, NH4HS, NH4Br, and NH4Fusing fundamental thermodynamic equations of state with published thermodynamic properties for the individual chemical species/reactions.

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.

Insight Into

Although most economists are skeptical of or puzzled by the Catholic concept of the common good, a rejection of the economic approach as inimical to the common good would be hasty and counterproductive. Economic analysis can enrich the common good tradition in four ways. First, economics embodies a deep respect for economic agency and for the effects of policy and institutions on individual agents. Second, economics offers a rich literature on the nature of unplanned order and how it might be shaped by policy. Third, economics offers insight into the public and private provision of various kinds of goods (private, public, common pool resources). Fourth, recent work on the development and logic of institutions and norms emphasizes sustainability rooted in the good of the individual.

Abstract End-user (e.g. patients or the public) testing of information material is becoming more common in the German public health care system. However, including the end-user (in this case patients) in an optimisation process and thus enabling a close collaboration while developing PIMs is still rare. This is surprising, given the fact that patients provide the exact perspective one is trying to address. Within the isPO project, a patient organization is included as a legal project partner to act as the patient representative and provide the patient's perspective. As such, the patient organization was included in the PHR approach as part of the PIM-optimisation team. During the optimisation process, the patients gave practical insights into the procedures of diagnosing and treating different types of cancer as well as into the patient's changing priorities and challenges at different time points. This was crucial information for the envisioned application of the individual PIMs and their hierarchical overview. Moreover, the developed PIM-checklist enabled the patients to give detailed feedback to the PIMs. With their experience of being in the exact situation in which the PIMs will be applied, their recommendations, especially on the wording and layout of the materials, have been a valuable contribution to the PIM optimisation process. In this part of the seminar, we will take a closer look at the following skill building aspects: What is gained from including patients as end-users in the development and optimization of PIM?How can we reach patients to contribute to a PIM optimization process? Which requirements and prerequisites do patients have to provide to successfully work on an optimisation team?How to compromise and weigh opinions when different ideas occur? Altogether, this part will construct a structured path of productive patient involvement and help to overcome uncertainties regarding a collaboration with patient organizations.

The coronavirus disease 2019 (COVID-19) pandemic has resulted in significant uncertainty for the global population. However, since not all population groups experience the impacts of the pandemic in the same way, the objective of this study was to identify the individual characteristics associated with the feeling of uncertainty during the lockdown that commenced in March 2020 in Greece. The study used data from the “Public Opinion in the European Union (EU) in Time of Coronavirus Crisis” survey. The sample consisted of 1050 individuals aged between 16 and 54 years. According to the analysis, which was based on a logistic regression model, the emotional status of older individuals, those who experienced income and job losses since the beginning of the pandemic, and middle-class and high-class individuals, is more likely to be described as a feeling of uncertainty. In addition, the emotional status of individuals with less concern for their own health and that of family and friends is less likely to be described as a feeling of uncertainty. Although the results related to age, income, and job losses, as regards concern for health, agree with the international literature, the limited health literacy of lower-class individuals may explain the reduced likelihood of their experiencing feelings of uncertainty. The results confirm the international literature describing several aspects of uncertainty due to the COVID-19 crisis.

Public Imagination

On 28 October 1918, a group of Czech nationalists stood on the steps of the Obecni Dům (Municipal House) in Prague and proclaimed their independence from the Austro-Hungarian Monarchy, allying themselves with the new state of Czechoslovakia. Their declaration marked the beginning of a new era in the Czech lands, one in which Czechs, as the majority nation, hoped to redefine the terms of political discourse. The new Czechoslovak Republic, its Czech supporters declared, would be the antithesis of the Habsburg regime. In the place of a multinational Monarchy, they would erect a democratic nation-state. The second half of this political vision was complicated by the fact that the new Czechoslovakia actually contained many ethnic groups, but Czechs still tended to imagine their new Republic as the political expression of the Czech nation. At the same time, this “Czech-centered” politics also emphasized the democratic basis of the new country. Czechoslovakia, Czech leaders said, would be a state governed by its people and dedicated to protecting their rights and freedoms as individuals. A political culture that rested on both ethnic nationalism and democratic values obviously contained some internal tensions: the need to protect the interests of one specific nation and the duty to protect the individual rights of all citizens could rub uncomfortably against each other. Yet, at that moment in 1918, most Czechs failed to register this potential for ideological conflict, instead seeing an essential link between democratic politics and the good of the Czech nation. For many Czechs, democracy itself was a need of the nation, a political structure crucial to Czech national self-realization. This idea came from one prominent conception of Czech nationhood that had captured the public imagination in the fall of 1918. According to this strain of Czech national ideology, the Czech nation had a sort of democratic character. This meant that only an egalitarian, democratic government would suit a “Czech” state. So, paradoxically, a universal language of rights and freedoms was the key to building a truly national Czechoslovak Republic. It was with a state that emphasized equality and personal freedom that the Czechs would fulfill their national destiny.

The Impact

In this article, we examine the individual predictors that are responsible for accurate beliefs about the link between vaccinations and autism. We then show how these beliefs affect policy preferences about vaccines. We derive two hypotheses from motivated reasoning theory and test these on national survey data from Gallup and CBS News. Republicans were less likely to report accurate beliefs than Democrats. In addition, educational attainment modified the impact of party identification. The gap between Republicans and Democrats in likelihood of reporting accurate beliefs was largest among the most educated portion of the public. Finally, we show that accurate beliefs about vaccines, independent of statistical controls, are important predictors of policy attitudes about unvaccinated children attending public school and parental choice about the decision to vaccinate. We discuss the theoretical and practical significance of these findings.

The Solitary Sphere in the Age of Virgil uses an enriched tripartite model of Roman culture—touching not only the public and the private, but also the solitary—in order to present a new interpretation of Latin literature and of the historical causes of this third sphere’s relative invisibility in scholarship. By connecting Cosmos and Imperium to the Individual, the solitary sphere was not so much a way of avoiding politics as a political education in itself. As reimagined by literature in this age, this sphere was an essential space for the formation of the new Roman citizen of the Augustan revolution, and was behind many of the notable features of the literary revolution of Virgil’s age: the expansion of the possibilities of the book of poetry, the birth of the literary cursus, new coordinations of cosmology and politics within strictly organized schemes, the attraction of first-person genres, and the subjective style. Through close readings of Cicero’s late works and the oeuvres of Virgil, Horace, and Propertius and the works of other authors in the age of Virgil, The Solitary Sphere thus presents a radical reinterpretation of classical Roman literature, and contributes to the study of premodern culture more generally, especially for traditions that have taken antiquity as too fixed a point in their own literary, religious, and cultural histories.

Before the COVID-19 pandemic forced large sections of the workforce to work from home, the uptake of working from home in the public sector had been limited and subject to the discretion or ‘allowance decisions’ of individual managers. Allowance decisions are influenced by factors at the organisational, group and individual levels. This research examines managers’ allowance decisions on working from home at each of these levels. It compares two qualitative datasets: one exploring managerial attitudes to working from home in 2018 and another dataset collected in mid-2020, as Australia transitioned out of the initial pandemic lockdown. The findings suggest a change in the factors influencing managers’ allowance decisions. We have identified a new factor at the organisational level, in the form of local organisational criteria. At the group level, previous concerns about employee productivity largely vanished, and managers experienced an epiphany that working from home could be productive. At the individual level, a new form of managerial discretion emerged as managers attempted to reassert authority over employees working remotely. These levels intersect, and we conclude that allowance decisions are fluid and not made solely by managers but are the result of the interactions between the organisational, group and individual levels.
