Abstract Species inventories are important tools to evaluate biodiversity losses and contribute to the conservation of endangered areas. The Amazon and Cerrado are the largest Brazilian biomes and represent some of the most threatened regions of the country. Due to its location between these biomes, the state of Maranhão, Northeast Brazil, possesses a great variety of habitats and a high local diversity. Nonetheless, few faunistic inventories of diversified groups have been performed in the state. In the specific case of butterflies, a well-known biological indicator, no inventories have been published in the past years. This study aimed to expand the knowledge on the composition of butterflies in Amazon and Cerrado remnants of Maranhão. Butterflies were sampled between 2011 and 2015 across eight municipalities of the state. Captures were made through entomological nets and baited traps. In total, 189 species were sampled, of which 165 were captured in the Amazon, 65 in the Cerrado and 41 in both biomes. We sampled 167 species through entomological nets and 43 through baited traps, representing 12% of similarity in species composition between sampling methods. We estimate that the recorded species represent a small subset of the butterflies from Maranhão. Therefore, long-term researches in poorly studied areas of the state are recommended to identify novel and/or endemic taxa.

Abstract Discarding of commercially important fish species in the bottom trawl fisheries in the northern Mediterranean Sea was investigated by soliciting the long-term recollections of fishers engaged or formerly engaged in such fisheries. The main aim of our investigation was to describe the prevalence of discarding and its evolution over the past 70 years using information gathered through individual questionnaire-based interviews with fishers from ports in Spain, Italy, and Greece, following a standardized sampling protocol. Although it proved impossible to derive absolute estimates of the volume of discarded catches over the period investigated, we conclude that over the past 70 years, discarding as a practice has gradually increased in the northern Mediterranean trawl fisheries and has been accompanied by a shift in the species composition of the discarded catch. While discarding can occur for a number of reasons, our investigations indicate that discarding in the past was mostly driven by market demand, but recent legal and regulatory constraints have led to changes in fishing strategies and became a significant reason for discards.

Caves are the best studied aquatic subterranean habitat, but there is a wide variety of these habitats, ranging in depth below the surface and size of the spaces (pore or habitat size). Both factors are important in setting limits to species composition and richness. In addition to caves, among the most important shallow aquatic subterranean habitats are the hyporheal (underflow of rivers and streams), the hypotelminorheal (very superficial drainages with water exiting in seeps), epikarst, and calcrete aquifers. Although it is little studied, both body size and species composition in the different habitats is different. Because of high levels of endemism and difficulty in access, no subterranean habitats are well sampled, even caves. However, there are enough data for robust generalizations about some geographic patterns. Individual hotspot caves are concentrated in the Dinaric region of southern Europe, and overall, tropical regions have fewer obligate aquatic cave dwellers (stygobionts). In all subterranean aquatic habitats, regional diversity is much higher than local diversity, but local diversity (especially single cave diversity) may be a useful predictor of regional species richness. In Europe there is a ridge of high aquatic subterranean species richness basically extending east from the French–Spanish border. Its cause may be either high productivity or that long-term temperature oscillations are at a minimum. With increased collecting and analysis, global and continental trends should become clearer.

Abstract Zoonotic visceral leishmaniasis (ZVL), caused by protozoans of the genus Leishmania, it is a worldwide of great importance disease. In the northeast region of Brazil, the state of Alagoas has an endemic status for ZVL. Thus, this work aimed to analyze the epidemiological situation of human and canine visceral leishmaniasis in Alagoas, Northeast, Brazil, from 2007 to 2013. We conducted a descriptive, observational, retrospective study using secondary data from the Notifiable Diseases Information System, the Center of Zoonosis Control of Maceió, and the Central Laboratory of Public Health of Alagoas. During the studied period, it was observed that the highest incidence of human visceral leishmaniasis was in 2011 and the lowest in 2013. On the other hand, canine visceral leishmaniasis had its highest incidence in 2007 and its lowest in 2012. Of the 55 municipalities in the State of Alagoas that showed human visceral leishmaniasis (HVL), São José da Tapera presented an average of 4.4 cases over the past five years, being classified as of intense transmission. Regarding canine visceral leishmaniasis, in the same studied period, 45,112 dogs were examined in the State, of which 4,466 were positive. It resulted, thus, in a 9.9% positivity rate. Conclusions: Our data are important because canine infection is an important risk factor for the human disease.

Marketing in general can have greater influence if a new, yet old, perspective on marketing is adopted—something akin to the original orientation of marketing. Adopting George Fisk’s definition of marketing and marrying it with notions derived from the institutional economist Karl Polanyi is proposed. The histories of marketing thought and of institutional economics are reviewed to demonstrate their affinity and similar origins. Fisk’s conceptualization of marketing as societies’ provisioning systems is shown to correspond with Polanyi’s conceptualization of economies as instituted processes, admitting more than the market and the state as ways economies have historically and cross-culturally integrated with society. The obsolete marketing mentality is that marketers, including macromarketers, are overly fixated on the market and ignore or overlook alternatives. The Fisk/Polanyi orientation will attract macromarketers interested in marketing and development, critical marketing, sustainability, alternative economies, and those interested in the long-term prospects of macromarketing. Adopting this old, but new, framework will connect the past with the future, permit macromarketers make a mark on a larger intellectual landscape and serve to invite scholars in this larger landscape to engage with macromarketing.

An indepth phycological comparison is presented for lakes Ontario, Erie, Huron, and Superior, based on extensive lake-wide surveys carried out during the past 12 years. This comparison was achieved by the application of standard and consistent identification, enumeration, and data-processing techniques. The resulting species composition data are voluminous and present a broad picture of the phytoplankton assemblage. Our data base has enabled us to assess the long-term floristic changes, knowledge of which is lacking in the Great Lakes. The species composition reflects more or less the current trophic status of these lakes. The preponderance of nannoplankton and phytoflagellates is the subject of our current experimental research, which includes the fractionation of chlorophyll a and carbon-14 uptake, toxicity studies of heavy metals upon various size fractions of algae, and the role of microalgae and ultraplankton in the transfer of contaminants via zooplankton grazing. The need for phycological research in the Great Lakes is expanding with decreasing eutrophication and the increasing problems of contaminants. The recovery, rehabilitation, and preservation of these vital freshwaters are the primary concern of the continuing Canadian research program in the Great Lakes.

Present shortages of mathematics and science teachers in secondary schools are not a new phenomenon. Such shortages have been present for at least 40 years, with only the magnitude of the shortages fluctuating. Nor is the cause of the shortages a new phenomenon. Just as school salary policy, with its reliance on the single salary schedule, has not provided competitive salaries for mathematics and science specialists in the past, it continues to create a shortfall in the number of qualified mathematics and science personnel willing to take teacher training and offer their services to schools. It is only by providing special increments to attract mathematics and science specialists that a long-term solution can be effected. Schools can accommodate such a change in policy through careful and systematic planning. Both the state and federal governments have roles to play in assisting schools to formulate salary policies that will attract adequate numbers of qualified teachers for all openings.

The past several decades of US intervention in Somalia produced violent destabilization, dysfunction, and uncertainty, creating refugee outflows and terrorist networks against which the US is currently tightening its security cordons. This paper argues that Somalia’s recent history as a stateless region offers a cautionary and tragic case study of the long-term damages that ensue when wealthy states that intervene in poorer states in the name of their own security instead cause insecurity and inequities that enable violence, and then in response to that violence enact further securitization to protect themselves against the consequences of that damage. But rather than focusing on the state as a site of securitization, I focus on those whose lives are made insecure by the retreat of their state government and the imposition in its place of security regimes that are not created by their own state government. Such security regimes overlap and compete, are instituted by different state and nonstate actors for different purposes, and by their incoherence and multiplicity raise questions about the definition, location, and relevance of the state in such regions. The paper explores the emergence of new, interlinked security regimes that are partially or wholly constituted through the logics of a new security empire designed to respond to US security concerns. By turning attention to the situations faced by those who live within the insecurities of stateless regions, the paper asks, what happens to the concept of securitization when the national-territorial state is not the entity that operates as a ‘state’ in the lives of people, even though their lives are overlain with multiple and overlapping regimes of securitization?

ABSTRACTThe role of post-1991 ethnic-based federalism on conflicts along regional boundaries has been a topic of great dispute in Ethiopianist literature. This article sheds new light on the on-going debate based on original ethnographic material from the Afar-Tigray regional border zone. Contrary to other studies, conflicts appear to have reduced in that area. Two key questions are addressed: how do different groups lay future claims to land; and which role does the post-1991 government play in those claims to land and in reducing conflicts? The case study reveals that people materialise religion to lay future claims to land and that conflicts have reduced with increased involvement of the state over the past two decades, but that this reduction has come at a high cost and may therefore not be sustainable in the long term.

In light of the ongoing COVID-19 pandemic, it is becoming increasingly important to address the problem of resourcefulness in the healthcare personnel of COVID-19 red zones. The aim of this study was to assess hardiness and the state of vital resources in physicians continuously working in red zones and to test a hypothesis that that long-term work in a COVID-19 red zone adversely affects the resourcefulness, reducing resistance to stress. Group 1 (n = 94) consisted of physicians with a history of employment in a COVID-19 red zone between May 2020 and June 2021; group 2 (n = 77) comprised physicians who were not involved in managing COVID-19 patients. The tests showed that hardiness and its components (commitment, control and challenge) were at high levels in group 2 (59.7%; 67.5%; 61.0%; 20.9%, respectively). The index of resourcefulness (RI; 1.24) reflected the prevalence of personal gains over losses in group 1 over the past year. In this group, there were no sex differences in the results. By contrast, hardiness was significantly reduced in 31.9% of the respondents in group 1 (red zone). Working in the red zone had a devastating effect on all hardiness components: the ratio of the percentages of high to low values was 8.5/27.7 for commitment, 9/6/34.0 for control and 10.6/35.1 for challenge. RI was reduced (0.77). The most pronounced loss of resources was observed in female physicians. The study found a significant mutual impact between challenge and the state of personality resources in red zone staff, which may indicate activation of proactive coping strategies and the acceptance of new professional experience.

Norway, it is claimed, has the most social anthropologists per capita of any country. Well connected and resourced, the discipline – standing apart from the British and American centres of anthropology – is well placed to offer critical reflection. In this book, an inclusive cast, from PhDs to professors, debate the complexities of anthropology as practised in Norway today and in the past. Norwegian anthropologists have long made public engagement a priority – whether Carl Lumholz collecting for museums from 1880; activists protesting with the Sámi in 1980; or in numerous recent contributions to international development. Contributors explore the challenges of remaining socially relevant, of working in an egalitarian society that de-emphasizes difference, and of changing relations to the state, in the context of a turn against multi-culturalism. It is perhaps above all a commitment to time-consuming, long-term fieldwork that provides a shared sense of identity for this admirably diverse discipline.
