Abstract Housing sows in groups creates the challenge of decreasing fighting amongst sows. One proposed method to do so is to feed a high tryptophan diet, but the effect on the fetus is unkown. To investigate this, 66 sows were fed 1 of 3 diets: Control (0.14 % SID tryptophan), Medium (0.28 % SID tryptophan), or High (0.4 2% SID tryptophan), from d 28 to 35 of gestation. Sows gestated in standard gestation stalls. Blood samples were taken on d 27 prior to and on d 35 after tryptophan supplementation. On d 1 and d 2, 3 nursing bouts were observed so as to record disputes and displacements from teat competition. The piglets’ activity and fighting were recorded on d 3, 7, and 11 from 0700 h to 1700 h. On d 12, 4 piglets per litter were blood sampled, 2 to be used in later behavior tests and 2 to act as controls for blood cortisol levels. On d 14, the 2 behavior test piglets from each litter were subjected to a 10-min Isolation Test and 5-min Human Approach Test. On d 15, the behavior test piglets were paired by sex and treatment (for example, a male Medium piglet paired with another male Medium piglet from a different crate) and each pair was subjected to a 10-min Social Challenge Test and immediately blood sampled. Piglet cortisol and serotonin did not differ among treatments (P > 0.10). There were no differences (P > 0.10) for number born (12.7 ± 0.4), born alive (11.7 ± 0.4), or mortality (1.1 ± 0.2). Behavior during nursing bouts was similar, with no treatment differences in number of disputes or displacements, and similar bout lengths among treatments (199.5 ± 4.6 s, P > 0.10). No differences were detected for any of the variables for Isolation or the Human Approach Tests (P > 0.10). During the Social Challenge Test, High piglets had more contacts approaching the head of the companion piglet than did either Medium or Control piglets (14.3 ± 1.1, 10.7 ± 1.1, and 9.69 ± 0.8 respectively, P < 0.02). Total number of aggressive interactions during the test tended to be greater for Medium piglets compared to High piglets (9.3 ± 1.5 vs 5.1 ± 0.9, P < 0.07). Time budget data of the litter indicate that piglets from all 3 treatments spent equal amounts of time active and inactive (P > 0.10). Aggression was low with 0.3 ± 0.04 % of piglets displaying aggressive behavior. Feeding high concentrations of tryptophan for a short duration early in gestation does not have a negative impact on sows’ subsequent offspring.

The article examines the contribution of the representatives of the Samarin family to the development of the Parish issue in the Russian Empire in the late 19th and early 20th centuries. The issue of expanding the rights of the laity in the sphere of parish self-government was one of the most debated problems of Church life in that period. The public discussion was initiated by D.F. Samarin (1827-1901). He formulated the “social concept” of the parish and parish reform, based on Slavophile views on society and the Church. In the beginning of the twentieth century his eldest son F.D. Samarin who was a member of the Special Council on the development the Orthodox parish project in 1907, and as such developed the Slavophile concept of the parish. In 1915, A.D. Samarin, who took up the position of the Chief Procurator of the Most Holy Synod, tried to make his contribution to the cause of the parish reforms, but he failed to do so due to his resignation.

The aging is not only a personal but also a social challenge from several aspects, several dimensions; a challenge aiming to build system approaches and solutions with a long term importance. Aims: the main aim of this research is to investigate the conditions and challenges in the modern living of the old people, primarily in terms of the social care. However, this research is concentrated on a big group of the population and their challenges are the most intensive in the modern living. The investigation of the conditions and challenges in the aging are basis and encouragement in realizing the progressive approaches in order to improve the modern living of the old people. The practical aim of the research is a deep investigation and finding important data, analyzing the basic indicators of the conditions, needs and challenges in order to facilitate the old population to get ready for the new life. Methods and techniques: Taking into consideration the complexity of the research problem, the basic methodological approach is performed dominantly by descriptive-analytical method. The basic instrument for getting data in the research is the questionnaire with leading interview for the old people. Results: The research showed that the old people over 70-79 years old in a bigger percentage manifested difficulties primarily related to the functional dependency, respectively 39,33 % of the participants in this category showed concern about some specific functional dependency from the offered categories. The percentage of the stomach diseases with 38,33 % is important, as well as the kidney diseases with 32,83% related to the total population and the category of the old people over 80. Conclusion: The old people very often accept the life as it is, often finding things fulfilled with tolerance and satisfaction. However the health problems of the old people are characterized with a dominant representation. The chronic diseases and the diseases characteristic for the aging are challenge in organizing adequate protection which addresses to taking appropriate regulations, programs and activities.

It is an honour for me as President of the Pakistan Society of Development Economists to welcome you to the 13th Annual General Meeting and Conference of the Society. I consider it a great privilege to do so as this Meeting coincides with the Golden Jubilee celebrations of the state of Pakistan, a state which emerged on the map of the postwar world as a result of the Muslim freedom movement in the Indian Subcontinent. Fifty years to the date, we have been jubilant about it, and both as citizens of Pakistan and professionals in the social sciences we have also been thoughtful about it. We are trying to see what development has meant in Pakistan in the past half century. As there are so many dimensions that the subject has now come to have since its rather simplistic beginnings, we thought the Golden Jubilee of Pakistan to be an appropriate occasion for such stock-taking.

Emerson’s Memory Loss is about an archive of texts documenting Emerson’s intellectual state during the final phase of his life, as he underwent dementia. It is also about the way these texts provoke a rereading of the more familiar canon of Emerson’s thinking. Emerson’s memory loss, Hanlon argues, contributed to the shaping of a line of thought in America that emphasizes the social over the solipsistic, the affective over the distant, the many over the one. Emerson regarded his output during the time when his patterns of cognition transformed profoundly as a regathering of focus on the nature of memory and of thinking itself. His late texts theorize Emerson’s experience of senescence even as they disrupt his prior valorizations of the independent mind teeming with self-sufficient conviction. But still, these late writings have succumbed to a process of critical forgetting—either ignored by scholars or denied inclusion in Emerson’s oeuvre. Attending to a manuscript archive that reveals the extent to which Emerson collaborated with others—especially his daughter, Ellen Tucker Emerson—to articulate what he considered his most important work even as his ability to do so independently waned, Hanlon measures the resonance of these late texts across the stretch of Emerson’s thinking, including his writing about Margaret Fuller and his meditations on streams of thought that verge unto those of his godson, William James. Such ventures bring us toward a self defined less by its anxiety of overinfluence than by its communality, its very connectedness with myriad others.

This chapter discusses the role of energy in economic development, the transformation of energy markets, trade in energy resources themselves, and the geopolitical dynamics that result. The transformation of energy markets and their expansion via trade can help or hinder development, depending on the processes behind them and how stakeholders interact. The availability of renewable, climate-friendly sources of energy, domestically and internationally, means that there is no inherent trade-off between economic growth and the use of fossil fuels. The existence of economic, political, social, and geopolitical adjustment costs means that the expansion of international energy markets to incorporate alternatives to oil and coal is a complex balance of environmental trade-offs with no solutions completely free of negative impact risk. An understanding of the supply of and demand for energy must incorporate the institutional context within which they occur, as well as the social and political dynamics of their setting.

What accounts for the endurance of forced marriage (kahwin paksa) narratives in Malaysian public culture? How does one explain the ways popular fascination with forced marriage relate to assumptions about heteronormative institutions and practices? In a society where most who enter into marriages do so based on individual choice, the enduring popularity of forced marriage as a melodramatic trope in fictional love stories suggests an ambivalence about modernity and egalitarianism. This ambivalence is further excavated by illuminating the intertextual engagement by readers, publishers and booksellers of Malay romantic fiction with a mediated discourse on intimacy and cultural practices. This article finds that forced marriage in the intimate publics of Malay romance is delivered as a kind of melodramatic mode, a storytelling strategy to solve practical problems of experience. Intertextual narratives of pain and struggle cast light on ‘redha’ (submission to God’s will) and ‘sabar’ (patience), emotional virtues that are mobilised during personal hardship and the challenge of maintaining successful marital relations. I argue that ‘redha’ and ‘sabar’ serve as important linchpins for the reproduction of heteronormative institutions and wifely obedience (taat). This article also demonstrates the ways texts are interwoven in the narratives about gender roles, intimacy, and marital success (or lack thereof) and how they relate to the modes of romantic melodrama.

In the social upheaval arising from the coronavirus disease 2019 (COVID-19) pandemic, we do not yet know how union formation, particularly marriage, has been affected. Using administration records—marriage certificates and applications—gathered from settings representing a variety of COVID-19 experiences in the United States, the authors compare counts of recorded marriages in 2020 against those from the same period in 2019. There is a dramatic decrease in year-to-date cumulative marriages in 2020 compared with 2019 in each case. Similar patterns are observed for the Seattle metropolitan area when analyzing the cumulative number of marriage applications, a leading indicator of marriages in the near future. Year-to-date declines in marriage are unlikely to be due solely to closure of government agencies that administer marriage certification or reporting delays. Together, these findings suggest that marriage has declined during the COVID-19 outbreak and may continue to do so, at least in the short term.

Abstract This article examines banditry, embezzlement, and other insider crimes along Egyptian railway lines during a period when British officials exerted centralized control over the Egyptian railway and financial austerity had a negative impact on the rail sector. By exploring the motives and tactics of railway crimes, I posit that criminals, by making claims on and use of the technology outside the purview of state regulations, expressed their heterogeneous desires to redistribute social wealth, repurpose the technological promise of modern railways, and confound intentions of colonial governance. Using new archival materials, this article utilizes a bottom-up approach to examine grassroots activism, everyday knowledge, informal networks, and the social mores and norms that criminals harnessed to discern infrastructural vulnerabilities and elude surveillance from the colonial state. Ultimately, I contend that criminal acts uncovered social crises otherwise hidden under the shadow of the exterior prosperity and stability of late 19th-century Egypt.

Industries are nowadays not only expected to produce goods and provide services, but also to do this sustainably. What qualifies a company as sustainable implies that its activities must be defined according to the social and ecological responsibilities that are meant to protect the society and the environment in which they operate. From now on, it will be necessary to consider and measure the impact of industrial activities on the environment, and to do so, one key parameter is the carbon footprint. This paper demonstrates the utility of the LCI as a tool for immediate application in industries. Its application shall facilitate decision making in industries while choosing amongst different scenarios to industrialize a certain product with the lowest environmental impact possible. To achieve this, the carbon footprint of a given product was calculated by applying the LCI method to several scenarios that differed from each other only in the supply-chain model. As a result of this LCI calculation, the impact of the globalization of a good’s production was quantified not only financially, but also environmentally. Finally, it was concluded that the LCI/LCA methodology can be considered as a fundamental factor in the new decision-making strategy that sustainable companies must implement while deciding on the business and industrial plan for their new products and services.

The notion that the Earth has entered a new epoch characterized by the ubiquity of anthropogenic change presents the social sciences with something of a paradox, namely, that the point at which we recognize our species to be a geologic force is also the moment where our assumed metaphysical privilege becomes untenable. Cultural geography continues to navigate this paradox in conceptually innovative ways through its engagements with materialist philosophies, more-than-human thinking and experimental modes of ontological enquiry. Drawing upon the philosophy of Gilbert Simondon, this article contributes to these timely debates by articulating the paradox of the Anthropocene in relation to technological processes. Simondon’s philosophy precedes the identification of the Anthropocene epoch by a number of decades, yet his insistence upon situating technology within an immanent field of material processes resonates with contemporary geographical concerns in a number of important ways. More specifically, Simondon’s conceptual vocabulary provides a means of framing our entanglements with technological processes without assuming a metaphysical distinction between human beings and the forces of nature. In this article, I show how Simondon’s concepts of individuation and transduction intersect with this technological problematic through his far-reaching critique of the ‘hylomorphic’ distinction between matter and form. Inspired by Simondon’s original account of the genesis of a clay brick, the article unfolds these conceptual challenges through two contrasting empirical encounters with 3D printing technologies. In doing so, my intention is to lend an affective consistency to Simondon’s problematic, and to do so in a way that captures the kinds of material mutations expressive of a particular technological moment.
