Detailed data on the response of plants to different climatic conditions could gain insight into the early impacts of climate change upon functioning ecosystems especially alpine ones, the most specialized. <em>Petasites kablikianus</em> (Asteraceae) is a species with montane and disjunctive distribution range, and it is one of the best objects to such investigations. In Polish high mountains, it is represented the best on the northern slopes of the Babia Góra massif (the Babiogórski National Park) and it occurs in two, independent zones: subalpine (landslides, rock rubbles) and lower montane zone (gravels on stream banks). The climatic differences between these two zones result in a morphological differentiation of specimens but mainly in differences in the dynamics of the life history of both populations. Detailed phenological observations and biometrical measurements were made on five plots on both gynodynamic and androdynamic shoots in their natural environment and after transplantation. The most important result is a fact that the subalpine population is completely phenologically isolated. Moreover the differences in the dates of beginning vegetation and in the duration and dynamics of particular stages of development and in morphological structure of individuals between the upper and lower populations were also stated. The results show that the adaptability of the species present a great potential to respond to the possible effects of global warming by modifying the life history and extending of distribution range for low-lying areas.

Recent academic research highlights the role of leadership identity when thinking about the improvement of the educational field. Based on this research, this article aims to identify and analyze the elements that affect the development of leadership identity in female school principals within the Chilean context. This is achieved by working from a biographical-narrative approach, specifically from the life history technique. This analysis emerges from a considerate reflection on the teachings, and personal and professional milestones highlighted in the biogram. Both personally and professionally, a multiplicity of elements is observed in the life history of María Eliana, influencing the development of her leadership identity, particularly highlighting her self-recognition as a woman. This identity is oriented towards social justice, based on socio-emotional tools such as care, empathy, and participation; and understands and values the role these elements must take in Chilean education. The case study presents tensions for the Chilean educational system, which must be able to address the complexities that women experience while holding leadership positions, especially when challenged with the perspective that school is an inclusive space of social justice.

This case study looks at the postgraduate program in Criminology and Police Science at the Ruhr- University Bochum, Germany. This practice oriented course of study is designed as a distance learning course (blended learning) and therefore focuses on techniques of e-learning. The case study describes the history of origins and examines the educational situation before this master’s program was established and how an idea became reality. It is one of the very few possibilities in Germany to receive a deeper insight into criminology and police science. Despite the fact, that the students are all professionals and thus working mostly full time, the technical premises make a discourse possible as in on-campus programs. These innovative forms of learning are the focal point of the following case study. It is our aim to provide insight into how a master’s program could be set up and to promote new concepts of e-learning in the field of criminology.

Abstract This article presents the history of a printing press that operated at several places near Berlin during the first half of the eighteenth century, culminating in the epoch-making reprinting of Maimonides’ Guide of the Perplexed in 1742. The press was established in Dessau in 1694 by the court Jew Moses Wulff (1661–1729), and was run by several printers, notably the convert Israel b. Abraham (fl. 1715–1752). Using the trajectory of the Wulff press as a case study, I examine the relations between scholars, patrons of learning (especially court Jews), printers, and book publishing. The inquiry will highlight the considerable role that court Jews played in shaping the Jewish bookshelf, notably by choosing which books (reprints and original) would be funded. Surprisingly perhaps, although court Jews were in continuous contact with the environing culture, they did not usually favor the printing of non-traditional Jewish works that would favor a rapprochement.

How does the communication of information affect the pipeline industry? People are becoming more aware of the pipeline industry and how it may affect individuals and landowners in the future. Corporations are producing commuications tools to alleviate the lack of knowledge and the hidden value of energy pipelines. This case study examines two projects: “Passing through Edson” examines a winter pipeline construction job in Edson, Alberta. The story is told by the people on the job. We examine the environmental issues, economic impact, Native employment, and winter construction techniques. The “Boy Chief” video examines the impact of an archaeological dig on the prairies. In this program we have insight into the aboriginal history of the area and how the pipeline company is helping people learn more about the Native way of life. The paper examine how communication tools like these, allow employees access to information when communicating to stakeholders.

Based on three years of participant observation, this article provides insight into the working relationship between a small business owner and undocumented immigrant workers at a Korean-Japanese restaurant. The case study focuses on a Korean American businesswoman who depends on the unpaid labor of family members and the cheap labor of undocumented immigrants. Using naturalistic ethnography, which consists of casual interactions and conversations with informants, the author relates the life history of the owner, Mrs. Kwon, who asks her employees to call her “Mama,” and analyzes her preference for undocumented immigrant workers. The article elucidates the ways she asserts power and control in the workplace.

This paper extends the research conducted on male bonding in locker rooms to another well-known but under-researched site, the campus bar. Through a life history of a former athlete, we learn about the connection between what is said in the locker room and behavior outside. We also gain insight into the role campus bars play in facilitating aggression and sexual misconduct by male athletes.

Abstract We studied nine populations of Salamandrina perspicillata for two to nine years and described the life history variation among these population. Despite experiencing similar climatic conditions, populations differed in mean body size: populations using still water bodies for oviposition were larger body-sized than those using brooks. One semi-natural pond was used by particularly small individuals and was probably recently colonised. The mean body size of ovipositing females varied from year to year. Measurements of individuals in successive years showed that the tail grew more than the trunk and this differential growth increased with age. Females did not oviposit every year and, within a given population, the number of ovipositing females varied widely from year to year.

Research in the service of politics? The case of Józef ObrębskiThe paper concentrates on the circumstances of the production of anthropological knowledge, created in a dynamic tension between its cognitive goal and the way it is used for political purposes. It provides an insight into a complex network of conditions (intelectual, institutional, financial, personal, political) which determined the production of knowledge in interwar Poland within the then emerging disciplines of ethnology and sociology, in the scope of what today we would call social anthropology.This case study takes a closer look at Polish anthropologist Józef Obrębski (1905-1967), a close student of Malinowski, whose outstanding achievements remained mostly unpublished and thus never came into existence in the master narrative of the history of our discipline. In the 1930s Obrębski conducted ethnosociological field research in the Polesie region in eastern Poland (nowadays, part of Belarus and Ukraine), which was part of a large scale scientific project of the Commission for Scientific Research of the Eastern Territories. This project, financed by the Polish government and headed by a politician, general Kasprzycki, was supposed to be an efficient tool in the politics of the so called state and national assimilation of the Slavic-speaking ethnic minorities. Obrębski’s political views, which were democratic and liberal in character, were opposed to the official political line whereas his functionalist anthropological stance was unacceptable for the mainstream Polish ethnology of the era, still rooted in the positivist paradigm.Anthropological knowledge produced by Obrębski, which we would call today a postcolonial and constructivist approach, began to find recognition only after his death. The biography of this scholar and the story of his “unknown” work, a great example of a non-mainstream phenomenon in a provincial country, makes it easier to reveal undisclosed mechanisms of the system and the thought-collectives of science. Nauka na usługach polityki? Przypadek Józefa ObrębskiegoArtykuł dotyczy uwarunkowań produkcji wiedzy antropologicznej w dynamicznym napięciu między jej celem poznawczym a zastosowaniem do celów politycznych. Przynosi wgląd w złożoną sieć uwarunkowań (intelektualnych, instytucjonalnych, finansowych, personalnych, politycznych) produkcji wiedzy w międzywojennej Polsce, na polu młodych dyscyplin, jakimi były wówczas etnologia i socjologia, polu, które dzisiaj nazywamy antropologią społeczno-kulturową.Bohaterem tego studium przypadku jest polski antropolog Józef Obrębski (1905-1967), bliski uczeń Malinowskiego, którego wybitne prace w większości pozostały nieopublikowane, nie funkcjonują zatem w wielkiej opowieści o historii dyscypliny. W latach 1930. Obrębski prowadził etnosocjologiczne badania terenowe na Polesiu we wschodniej Polsce (region ten dziś należy do Białorusi i Ukrainy), w ramach wdrażanego tam na szeroką skalę programu naukowego Komisji Naukowych Badań Ziem Wschodnich. Projekt ten, finansowany przez polski rząd i kierowany przez polityka, gen. Kasprzyckiego, miał być skutecznym narzędziem polityki asymilacji państwowej i narodowej słowiańskojęzycznych mniejszości etnicznych. Demokratyczne i liberalne poglądy polityczne Obrębskiego były opozycyjne wobec linii politycznej jego mocodawców, zaś stanowisko teoretyczno-metodologiczne, związane z funkcjonalizmem, było z kolei nie do przyjęcia przez polskich etnologów głównego nurtu, przywiązanych do paradygmatu pozytywistycznego.Antropologiczne osiągnięcia Obrębskiego, które dziś sytuujemy w obrębie podejścia postkolonialnego i konstruktywistycznego, zaczęły zyskiwać uznanie dopiero po jego śmierci. Biografia uczonego i dzieje jego „nieznanych” prac, ważny przykład pozamainstreamowego fenomenu w prowincjonalnym kraju, przyczyniają się do poznania nieujawnionych mechanizmów systemu i kolektywów myślowych w nauce.
