This article is a presentation of specific recent results describing scaling limits of individual- based models. Thanks to them, we wish to relate the time-scales typical of demographic dynamics and natural selection to the parameters of the individual-based models. Although these results are by no means exhaustive, both on the mathematical and the biological level, they complement each other. Indeed, they provide a viewpoint for many classical time-scales. Namely, they encompass the timescale typical of the life-expectancy of a single individual, the longer one wherein a population can be characterized through its demographic dynamics, and at least four interconnected ones wherein selection occurs. The limiting behavior is generally deterministic. Yet, since there are selective effects on randomness in the history of lineages, probability theory is shown to be a key factor in understanding the results. Besides, randomness can be maintained in the limiting dynamics, for instance to model rare mutations fixing in the population.

Complete History

As mental disease is generally of longer duration than other diseases, especially as seen in asylums for the insane—as it may be of life-long duration, and may frequently recur, or threaten to recur, in a single individual—to obtain a perfect knowledge of insanity, its history should extend from the earliest symptoms, and its subject be traced throughout life. Hence statistics which are made from records extending over a greater number of years are much more valuable than those which embody the results of a shorter period. A perfect series of statistical tables would require to exhibit, as far as they can, the complete history of every case, from the commencement of the mental disease until the death of the individual. This, however, is almost impossible. Dr. Thurnam,∗ under peculiar circumstances, has been able to give a series of statistics which trace the history of individuals beyond the asylum walls; but in ordinary cases such completeness is not obtainable, and we must content ourselves with less perfect results. Generally the history of the patient ceases when he leaves the asylum, and any facts we may obtain in his subsequent career are so few, and possibly inaccurate, that they cannot be embodied as trustworthy statistics. The history of those dying in the asylum, and of those under observation for five years or more, is more complete; but such cases are only those in whom treatment has been unsuccessful. In the cases of readmission, however, we have generally more trustworthy data, and are thus enabled to trace many subjects of mental disease throughout life.

Physical Access

Any one collection of objects never tells the whole story. Enabling access to natural history collections by users external to a given institution, has a long history–even that great stay-at-home, Linnaeus, relied on specimens in the hands of others. Neglecting collections outside one’s institution results in duplication and inefficiency, as can be seen in the history of synonymy. Physical access had always been the norm, but difficult for the single individual. A student in the late 20th century had to decide if money were better spent going to one collection or another, or if the sometimes rather fuzzy photographs really represented the taxon she was working with. Loans between institutions were a way to provide access, but came with their own risks. The very individualised–to users as well as institutions–system of access provisioning still operates today but has fundamentally changed in several respects. The SYNTHESYS (Synthesis of Systematic Resources) projects brought a set of European institutions into a consortium with one aim: to provide access to natural history collections in order to stimulate their use across communities. The SYNTHESYS Transnational Access (TA) programme provided access not only to the collections of participating institutions, but also to infrastructures such as laboratories and analytical facilities. The trajectory of TA has led to a change in thinking about natural history collections, along with access to them. Because access has been subsidised at both the individual and institutional levels, participating institutions began to function more as a collective; one infrastructure, albeit loosely dispersed. In the most recent iteration of the SYNTHESYS programme, SYNTHESYS+, access has changed yet again with the times. Technological advances in imaging permit high-quality surrogates of natural history specimens to be exchanged more freely, and Virtual Access (VA) forms an integral part of the SYNTHESYS+ access programme, alongside TA. Virtual access has been operating for some time in the natural history collections community, but like TA, with individual scientists requesting images/sequences/scans from individual institutions or curators. VA, as a centralised service, will be piloted in SYNTHESYS+ in order to establish the basis for community change in access provisioning. But what next? Will we continue to need physical access to specimens and facilities as VA becomes increasingly feasible? As European collections-based institutions coalesce into the DiSSCo (Distributed System of Systematics Collections) infrastructure, will the model established in SYNTHESYS+ continue to function in the absence of centralised funding? In this talk, we will explore the trajectory of access through SYNTHESYS and provide some scenarios for how access to natural history collections–both physical and virtual–may change as we transition to the broader infrastructure that DiSSCo represents.

Abstract. Background: Self-esteem is a major contributor to risk for repeated suicide attempts. Prior research has shown that awareness of stigma is associated with reduced self-esteem among people with mental illness. No prior studies have examined the association between self-esteem and stereotype awareness among individuals with past suicide attempts. Aims: To understand the relationship between stereotype awareness and self-esteem among young adults who have and have not attempted suicide. Method: Computerized surveys were administered to college students (N = 637). Linear regression analyses were used to test associations between self-esteem and stereotype awareness, attempt history, and their interaction. Results: There was a significant stereotype awareness by attempt interaction (β = –.74, p = .006) in the regression analysis. The interaction was explained by a stronger negative association between stereotype awareness and self-esteem among individuals with past suicide attempts (β = –.50, p = .013) compared with those without attempts (β = –.09, p = .037). Conclusion: Stigma is associated with lower self-esteem within this high-functioning sample of young adults with histories of suicide attempts. Alleviating the impact of stigma at the individual (clinical) or community (public health) levels may improve self-esteem among this high-risk population, which could potentially influence subsequent suicide risk.

First Time

The nineteenth century introduced developments in science and medicine that made the eradication of pain conceivable for the first time. This new understanding of pain brought with it a complex set of moral and philosophical dilemmas. If pain serves no obvious purpose, how do we reconcile its existence with a well-ordered universe? Examining how writers of the day engaged with such questions, this book offers a compelling new literary and philosophical history of modern pain. The book provides close readings of novelists Charlotte Brontë and Thomas Hardy and political and natural philosophers John Stuart Mill, Harriet Martineau, and Charles Darwin, as well as a variety of medical, scientific, and popular writers of the Victorian age. The book explores how discussions of pain served as investigations into the status of persons and the nature and parameters of social life. No longer conceivable as divine trial or punishment, pain in the nineteenth century came to seem instead like a historical accident suggesting little or nothing about the individual who suffers. A landmark study of Victorian literature and the history of pain, the book shows how these writers came to see pain as a social as well as a personal problem. Rather than simply self-evident to the sufferer and unknowable to anyone else, pain was also understood to be produced between persons—and even, perhaps, by the fictions they read.

This article offers an analysis of the identity work of a black transgender woman through life history research. Identity work pertains to the ongoing effort of authoring oneself and positions the individual as the agent; not a passive recipient of identity scripts. The findings draw from three life history interviews. Using thematic analysis, the following themes emerge: institutionalisation of gender norms; gender and sexuality unintelligibility; transitioning and passing; and lastly, gender expression and public spaces. The discussion follows from a poststructuralist conception of identity, which frames identity as fluid and as being continually established. The study contends that identity work is a complex and fragmented process, which is shaped by other social identities. To that end, the study also acknowledges the role of collective agency in shaping gender identity.

The study of Aramaic Bible translations (Targumim) continues to be a valuable source of information, not only for uncovering the history of biblical interpretation but also for providing insights for the study of linguistics and translation techniques. In comparison with work done on the Pentateuchal Targumim and Targum Former Prophets, research on the individual books of Targum Minor Prophets has been scant. By providing an overview of selected source material this review seeks (i) to provide incentives for more focussed studies in the field of Targum Minor Prophets and (ii) to motivate new integrated research approaches which are now made possible with the assistance of highly developed software programmes.

Geographic distribution and habitat preferences of Saxicola rubicola rubicola (Linnaeus, 1766), S. maurus variegatus (S.G. Gmelin, 1774), and S. m. armenicus (Stegman, 1935) inhabiting the Caucasian Isthmus and adjacent areas are described in detail. We examined the individual, sexual, age, seasonal and geographical variations of seven main diagnostic features of both plumage and morphometrics (exactly, the length of wing and tail) using 381 skin specimens. Substantially improved diagnoses of S. m. variegatus and S. m. armenicus are provided. After a thorough examination of the materials and history of the expedition of Samuel Gmelin in 1768–1774, and his description of Parus variegatus, it was concluded that the type locality of this taxon was the vicinity of Shamakhi in Azerbaijan not Enzeli in North-Western Turkey. It is also shown the fallacy of the recently proposed attribution of the holotype of the northern subspecies S. m. variegatus to the southern taxon S. m. armenicus and synonymisation of these names, as well as the replacement of the name S. m. variegatus by its junior synonym S. m. hemrichii Ehrenberg, 1833 for the northern subspecies.

Songkhla Lake

Songkhla Lake Basin has a long history of at least 6,000 years and has a wide variety of tourism resources including nature, history, beliefs, culture and various traditions of the local people. It covers 3 provinces, the whole area of Phatthalung, 12 districts of Songkhla and 2 districts of Nakhon Si Thammarat Province. It has an area of approximately 8,727 square kilometers. There are many tourist attractions because the basin has a long history through different eras, natural, historic, ancient sites, and the culture of the local people. In 2018, both Thai and foreign tourists visited Songkhla and Phatthalung, which is the main area of Songkhla Lake Basin. The total number of tourists that came was 7,628,813 and 1,641,841 and an income of 68,252.64 and 3,470.96 million baht was generated from each province, respectively (Ministry of Tourism and Sports, 2020). Although Songkhla Lake Basin has various tourist attractions, the promotion of tourism with the involvement of government agencies in the past mainly focused on promoting tourism along with the tourist attractions rather than encouraging tourists to experience and learn the culture of the people living in the area; the culture that reflects the uniqueness of the people in the south. This study, therefore, aims to find creative tourism activities in SLB in order to increase the value of tourism resources, create tourism activities that are aligned with the resources available in the community and increase the number of tourists in the area. Data for this study were collected using a secondary source of data collection method. It was done through a literature review of related documents, texts, magazines, and research which focus on Songkhla Lake Basin as a guideline for designing tourism activities. The field survey was done through twelve community-based tourism sites in SLB to find creative tourism activities. Data on each activity were collected in detail by interviewing the tourism community leaders and the local people. Content analysis was used to describe the individual open-ended questions by focusing on the important issues and the information obtained was presented as a narrative.

Background: Attention deficit hyperactivity (ADHD) disorder is a neurodevelopmental disorder characterized by inattention, hyperactivity, disruptive behaviour, and impulsivity. Despite considered typical of children for a long time, the persistence of ADHD symptoms in adulthood gained increasing interest during the last decades. Indeed, its diagnosis, albeit controversial, is rarely carried out even because ADHD is often comorbid with several other psychiatric diosrders, in particular with bipolar disorders (BDs), a condition that complicates the clinical picture, assessment and treatment. Aims: The aim of this paper was to systematically review the scientific literature on the neurobiological, clinical features and current pharmacological management of ADHD comorbid with BDs across the entire lifespan, with a major focus on the adulthood. Discussion: The pharmacology of ADHD-BD in adults is still empirical and influenced by the individual experience of the clinicians. Stimulants are endowed of a prompt efficacy and safety, whilst non-stimulants are useful when a substance abuse history is detected, although they require some weeks in order to be fully effective. In any case, an in-depth diagnostic and clinical evaluation of the single individual is mandatory. Conclusions: The comorbidity of ADHD with BD is still a controversial matter, as it is the notion of adult ADHD as a distinct nosological category. Indeed, some findings highlighted the presence of common neurobiological mechanisms and overlapping clinical features, although disagreement does exist. In any case, while expecting to disentangle this crucial question, a correct management of this comorbidity is essential, which requires the co-administration of mood stabilizers. Further controlled clinical studies in large samples of adult ADHD-BD patients appear extremely urgent in order to better define possible therapeutic guidelines, as well as alternative approaches for this potentially invalidating condition.

Accounting educators no doubt agree that diversity is an important and much neglected part of accounting education. They further recognize that it is difficult to incorporate this important topic into the accounting curriculum. This paper describes the efforts of various professors to expose business and accounting students to the evolution of diversity issues related to the accounting profession by using the book A White-Collar Profession [Hammond, 2002]. A White-Collar Profession: African-American CPAs Since 1921 is a seminal work which presents a history of the profession as it relates to African-American CPAs and documents the individual struggles of many of the first one hundred blacks to become certified. This paper describes efforts of faculty at four different colleges to utilize this book in their teaching of accounting. Instructors found that students not only developed an enhanced awareness about the history of the accounting profession, but that other educational objectives were advanced, such as improved communication and critical thinking skills, increased social awareness, and empathy for others. African-American students, in particular, embraced the people in the book as role models, while most every student saw the characters as heroic in a day when the accounting profession is badly in need of role models and heroes. This is encouraging given the profession's concern with diversity and the attention and resources directed at increasing the number of minorities entering the profession.
