The End of an Era
AbstractThis historical reprint from Public Health Nursing (Ramsay, ) summarizes the history of public health nursing services rendered by the Red Cross from its creation in 1912 until their termination in June 1951. The author was a public relations writer for the Red Cross. The paper is historically important for it provides chronology and perspective on the role of the Red Cross institutionalizing public health nursing and home nursing care in the United States during the first half of the 20th century. Of note are the three nursing services through which the Red Cross operated, each denoting a particular time and focus...

"We're Still in a Struggle": Dine Resilience, Survival, Historical Trauma, and Healing
As part of a community/university collaborative effort to promote the mental health and well-being of Diné (Navajo) youth, we explored the relevance of addressing historical trauma and current structural stressors, and of building on individual and community strengths through healing and social transformation at multiple levels. Qualitative analyses of 74 ethnographic interviews with 37 Diné youth, parents, and grandparents suggested that a focus on historical trauma as a conceptual frame for behavioral health inequities, understood within the context of resilience and survival, is appropriate. Our findings a...

Tobacco and CVD: A Historical Perspective
Tobacco consumption, in the past few decades has arguably been established as one of the most significant preventable causes of mortality and morbidity globally . Recent projections estimate that tobacco kills at least 6 million people globally every year, which is much higher than the combined mortality caused by diseases such as acquired immunodeficiency syndrome, tuberculosis, and malaria . The low- and middle-income countries (LMICs) are the worst affected by the tobacco epidemic . It is estimated that by 2030, more than 80% of the tobacco-related deaths will occur in LMICs .

The use of teetaimed in Estonia, 1880s-1990s.
Abstract This research contributes to a better understanding of the criteria used for the selection of plants for making beverages. Worldwide, not only the leaves of Camellia sinensis, but also various other plants are used for making tea. We argue that the selection of plants for making tea (in Estonian teetaimed) depends on specific features possessed by or attributed to the plants. 54 plant taxa and one lichen were identified as being used for making tea, based on the analysis of Estonian historical handwritten archival records on plant use for the period from 1887 to 1994. The influence of popular literature on...

Leaf morphology shift linked to climate change.
Abstract Climate change is driving adaptive shifts within species, but research on plants has been focused on phenology. Leaf morphology has demonstrated links with climate and varies within species along climate gradients. We predicted that, given within-species variation along a climate gradient, a morphological shift should have occurred over time due to climate change. We tested this prediction, taking advantage of latitudinal and altitudinal variations within the Adelaide Geosyncline region, South Australia, historical herbarium specimens (n = 255) and field sampling (n = 274). Leaf width in the study taxon, D...

Mitochondrial D‐loop analysis reveals low diversity in Mangalica pigs and their relationship to historical specimens
SummaryThe genetic relationship between 195 Mangalica and 79 non‐Mangalica pigs was studied using mitochondrial D‐loop SNP genotyping. Altogether, 35 polymorphic sites and 27 haplotypes were identified. Of the haplotypes, eight and 16 are Mangalica and non‐Mangalica specific, respectively, while three contain both Mangalica and non‐Mangalica individuals. Genetic distance values and phylogenetic analysis indicate that Mangalica individuals are very closely related, and five haplotypes represent approximately 92% of the Mangalica pigs involved in the study, thus determining the major maternal lineages. In contrast to...

Space-wavenumber and time-frequency analysis for damage inspection of thin-walled structures
This article presents a dynamics-based methodology for accurate damage inspection of thin-walled structures by combining a boundary effect evaluation method (BEEM) for space–wavenumber analysis of measured operational deflection shapes (ODSs) and a conjugate-pair decomposition (CPD) method for time–frequency analysis of time traces of measured points. BEEM is for locating and estimating small structural damages by processing ODSs measured by a full-field measurement system (e.g. a scanning laser vibrometer or a camera-based motion measurement system). BEEM is a nondestructive spatial domain method based on slid...

The Discourse of Aging
Historical and epistemological developments contribute to and reinforce the underlying framework that categorizes antiaging discourse and healthy aging discourse. This discourse creates the question “Can we live longer or better?” and encompasses issues of quality versus quantity, dependency versus autonomy, and risk versus benefit. By positing this discourse as a dichotomous tension, the development can be traced through the examination of select examples of influential studies in the field of aging. For nursing, the risk of these continued oppositions is potential oversimplification that may limit discernment of the ...

Asepsis and bacteriology: a realignment of surgery and laboratory science(1).
Abstract This paper examines the origins of aseptic surgery in the German-speaking countries. It interprets asepsis as the outcome of a mutual realignment of surgery and laboratory science. In that process, phenomena of surgical reality were being modelled and simplified in the bacteriological laboratory so that they could be subjected to control by the researcher's hands and eyes. Once control was achieved, it was being extended to surgical practice by recreating the relevant features of the controlled laboratory environment in the surgical work place. This strategy can be seen in the adoption of Robert Koch's bac...

'Looking as little like patients as persons well could': hypnotism, medicine and the problem of the suggestible subject in late nineteenth-century britain.
Abstract During the late nineteenth century, many British physicians rigorously experimented with hypnosis as a therapeutic practice. Despite mounting evidence attesting to its wide-ranging therapeutic uses publicised in the 1880s and 1890s, medical hypnosis remained highly controversial. After a decade and a half of extensive medical discussion and debate surrounding the adoption of hypnosis by mainstream medical professionals - including a thorough inquiry organised by the British Medical Association - it was decisively excluded from serious medical consideration by 1900. This essay examines the complex question ...

Re-visiting 'Galen in Tibet'(1).
Abstract This paper readdresses the assertion found in much secondary literature that Greek medicine was adopted in Tibet in the seventh and eighth centuries. I discuss some of the traces of Galenic medical knowledge in early Tibetan medicine, and raise the question of why Tibetan medical histories who mention Galen give Galenic medicine a much more significant place than is evidenced in the Tibetan medical literature itself. I discuss some historiographical considerations and argue that the centrality given to Galenic medicine is more indicative of the period in which these sources are written than of the period w...

Who Was He? Reflections on China's First Medical 'Naturalist'.
Abstract This paper examines the reasons why Physician He (Yi-He, sixth century BCE) was regarded as a founder in the classical medical tradition of China. By most accounts, Physician He's importance owes much to his theoretical innovations. In contrast to earlier healers, Physician He purportedly framed the aetiology of illnesses solely in terms of natural causes, as opposed to attributing sickness to gods or demons. In this paper, I reread a famous episode in the Commentary by Zuo, which is often cited as evidence of the physician's naturalism. By paying close attention to the formal elements of the narrative as ...

Sex ratio and women's career choice: Does a scarcity of men lead women to choose briefcase over baby?
Abstract Although the ratio of males to females in a population is known to influence behavior in nonhuman animals, little is known about how sex ratio influences human behavior. We propose that sex ratio affects women's family planning and career choices. Using both historical data and experiments, we examined how sex ratio influences women's career aspirations. Findings showed that a scarcity of men led women to seek high-paying careers and to delay starting a family. This effect was driven by how sex ratio altered the mating market, not just the job market. Sex ratios involving a scarcity of men led women to see...

Pharmacotherapy in type 2 diabetes: a functional schema for drug classification.
Abstract With growing awareness that long-term hyperglycemia is directly implicated in the tissue damage characteristic of diabetes, there has been a corresponding increase in clinicians' willingness to employ intensive treatment to achieve euglycemia, which may require diabetes drugs in combination. The expanding array of drugs with different mechanisms of action calls for a clear method of classification to guide rational combination therapy. Contemporary and historical literature was surveyed to document changes in awareness of toxicity from hyperglycemia and consequent changes in treatment strategy. References ...

Abstract Recent investigations give reason to question anew the historical status of the 'cell theory' as the ultimate driving force in the development of our understanding of life's processes at the most fundamental level. A revisitation of critical research papers and commentaries from the 19th Century shows that the disregarded (and historically maligned) 'protoplasmic theory of life' played a more deterministic role in the early advancement of knowledge on cell structure and function.

The interplay of mitochondria with calcium: An historical appraisal.
Abstract Indirect findings in the 1950s had indicated that mitochondria could accumulate Ca(2+), but only in 1961 isolated mitochondria were directly shown to take it up in a process driven by the activity of the respiratory chain or by the hydrolysis of added ATP. The uptake of Ca(2+) could be accompanied by the simultaneous uptake of inorganic phosphate, leading to the precipitation of hydroxyapatite in the matrix and to the effective buffering of the free Ca(2+) concentration in it. The uptake of Ca(2+) occurred via an electrophoretic uniporter that has been molecularly identified only recently. Ca(2+) was then ...

Revisiting the ants of Melanesia and the taxon cycle: historical and human-mediated invasions of a tropical archipelago.
Abstract Understanding the historical evolution of biotas and the dynamics of contemporary human-mediated species introductions are two central tasks of biology. One hypothesis may address both-the taxon cycle. Taxon cycles are phases of range expansion and contraction coupled to ecological and evolutionary niche shifts. These historical invasion processes resemble human-mediated invasions in pattern and possibly mechanism, but both the existence of historical cycles and the roles of recent introductions are in question. We return to the system that originally inspired the taxon cycle-Melanesian ants-and perform no...

Abstract Recent progress in the development of phylogenetic methods and access to molecular phylogenies has made comparative biology more popular than ever before. However, determining cause and effect in phylogenetic comparative studies is inherently difficult without experimentation and evolutionary replication. Here, we provide a roadmap for linking comparative phylogenetic patterns with ecological experiments to test causal hypotheses across ecological and evolutionary scales. As examples, we consider five cornerstones of ecological and evolutionary research: tests of adaptation, tradeoffs and synergisms among ...

Dengue and dengue-like outbreaks in the past: the case of the Macau epidemic fever of 1874.
Abstract Historical sources abound in references to outbreaks of a disease resembling dengue fever. Medical observers reported on its rapid onset and great expansion in the population, the diversity and changeability of its clinical features and its overall mildness. In 1874, an epidemic disease with fever, rash and rheumatic pains as main symptoms broke out in the Portuguese colony of Macau, South China. It was similar to the epidemic disease which swept the colony 2 years before during the socalled dengue pandemic of 1870-1873. The 1874 epidemic disease was variously labeled by local physicians, including dengue ...
