Mittlerweile verfügt die qualitative Sozialforschung über ein derart großes Fundament an Primärliteratur, dass auch ein stetiges Anwachsen der Sekundärliteratur zu beobachten ist. In diese Kategorie fällt auch – wie der im englischen Titel enthaltene Begriff Companion signalisiert – das hier besprochene Buch. Das Sammelwerk enthält eine Auswahl wichtiger Beiträge zu sozialwissenschaftlichen Ansätzen in der qualitativen Forschung. Die Auswahl der einbezogenen Kapitel wurde auf der Basis der beeindruckenden Anzahl von eintausend relevanten Titeln vorgenommen. Das Buch ist in drei Teile gegliedert: Im ersten Teil wird der Frage nachgegangen, wie wir Konzepte konstruieren und Theorien entwickeln, die wiederum das Forschungsdesign beeinflussen. Der zweite Teil beschäftigt sich mit methodologischen Fragen, u.a. mit dem Aufbauen von Glaubwürdigkeit, der Vermeidung von Voreingenommenheit und der Generalisierbarkeit von Forschungsergebnissen im Kontext kleiner Studien. Im dritten Teil werden sechs empirische Studien vorgestellt, denen jeweils verschiedene qualitative Ansätze zugrunde liegen, und die als exemplarisch für eine gute Forschungspraxis gelten können. Das Buch liefert bei einer hohen Qualität des Schreibstils wertvolle Ressourcen und einige angemessene Beispiele für qualitatives Forschungsdenken und -handeln.

Over a million people commit suicide worldwide every year. Taking an interdisciplinary approach that looks at the person at risk, the family and personal relationships they have and the communities in which they are embedded, this book with help anyone working with suicidal individuals to prevent this major cause of death. Backed up by research and clinical expertise the book clarifies the facts about suicide and debunks the many unfounded myths surrounding the subject. It covers the classifications and manifestations of suicide, as well as the major risk factors, at-risk groups and warning si

Seeks to document a responsive strategy to manufacturing planning
with Cussons (UK) Limited, a company operating in the fast moving
consumer goods (FMCG) industry. In the FMCG environment products are
manufactured to a sales forecast, and customers demand 100 per cent
service levels within lead‐times, sometimes in the order of hours rather
than days. It is essential that a company′s stock replenishment
procedures should reflect this situation rather than inhibit its ability
to respond. Manufacturing resource planning (MRPII), the standard for
planning and procurement used comprehensively within manufacturing
industry, is a tool that has been generally accepted and used within the
FMCG sector. It was not, however, either designed or developed to cope
with the specific demands imposed by this type of business. Suggests
that MRPII, rather than facilitating responsive planning, may actually
form a barrier to change.

AbstractThis article explores war remembrance and ritual in English schools. The Remembrance in Schools project (2013–2020) investigated remembrance practices in schools in England through questionnaires, interviews and observations. Schools are unique as sites of remembrance because children constitute the majority of participants in rituals. School‐based rituals of remembrance might potentially reproduce dominant discourses of war‐normalisation that conflate military values and nationalism with morally 'good' values and an imagined community of the nation. They also provide a contested, ambivalent space in which ambiguities of practice and thinking may encourage the emergence, in small ways, of counter‐narratives about war and its remembrance.

Each November, commemoration of the First World War armistice (and subsequent military events and conflicts) is almost ubiquitous in UK schools and has been given increased importance during the centenary years of the First World War. Yet as seemingly isolated occasions outside the regular curriculum, school practices of remembrance, and the understandings and perceptions surrounding them, have been subject to surprisingly little scrutiny. The Remembrance in Schools project (2013–19) investigates armistice commemoration in primary and secondary schools in three counties in southern England. This paper considers the theorisation of public commemorative rituals and relates this to teachers' reports of school-based events. It analyses teachers' accounts and perceptions, from survey and interview data, of the ways in which the First World War and subsequent conflicts are remembered, presented and discussed through school commemoration events. We conclude that such events mirror the 'social technologies' of public remembrance rituals. However, behind almost ubiquitous practices (the two-minute silence) and symbols (the poppy), these accounts reveal nuanced variations in teachers' views of the knowledge and values children gain from armistice commemoration in schools. These variations are inflected by individual schools' histories, community contexts, and pupil demographics, as well as teachers' own histories, values and ideals.

Antarctica is experiencing significant ecological and environmental change, which may facilitate the establishment of non‐native marine species. Non‐native marine species will interact with other anthropogenic stressors affecting Antarctic ecosystems, such as climate change (warming, ocean acidification) and pollution, with irreversible ramifications for biodiversity and ecosystem services. We review current knowledge of non‐native marine species in the Antarctic region, the physical and physiological factors that resist establishment of non‐native marine species, changes to resistance under climate change, the role of legislation in limiting marine introductions, and the effect of increasing human activity on vectors and pathways of introduction. Evidence of non‐native marine species is limited: just four marine non‐native and one cryptogenic species that were likely introduced anthropogenically have been reported freely living in Antarctic or sub‐Antarctic waters, but no established populations have been reported; an additional six species have been observed in pathways to Antarctica that are potentially at risk of becoming invasive. We present estimates of the intensity of ship activity across fishing, tourism and research sectors: there may be approximately 180 vessels and 500+ voyages in Antarctic waters annually. However, these estimates are necessarily speculative because relevant data are scarce. To facilitate well‐informed policy and management, we make recommendations for future research into the likelihood of marine biological invasions in the Antarctic region.

ABSTRACTThe zebra mussel, Dreissena polymorpha, is a major biofouling pest of water treatment works, irrigation systems and power stations in Europe and North America. This paper documents current problems associated with zebra mussels in English waterworks. Questionnaires and manual surveys conducted between 2001 and 2003 have revealed that over 30 water treatment works in England suffer problems associated with zebra mussels. Hundreds of tonnes of mussels are being removed each year from raw water intakes, pipelines and reservoirs. Problems have increased in. the last five years, due to a spread in the range of zebra mussels around England and the cessation of chemical treatment at the intakes of many treatment facilities during the 1990s. The importance of taking control of zebra mussels into account in planning new water supply schemes is highlighted.

AbstractThe substantial filtration capacity of freshwater mussels makes them attractive tools for environmental management. In this study, we applied a central composite design to estimate independent variables and establish optimal conditions of filtration rate and faeces production that enhance filtration of suspended organic matter by the freshwater mussel Sinanodonta woodiana. The results indicated that statistical design methodology offers an efficient and feasible approach for identifying optimal conditions for high filtration and low faeces production, using just a small number (30) of individuals. The proposed model equation takes into account the quantitative effect of variables and also the influence of interactions among variables on mussel filtration rate. Under the optimal experimental conditions (mussel size, 13.0 ± 0.2 cm; flow rate, 17.5 L/h), the experimental filtration rate of 4.47 ± 1.82 L/mussel/h showed a degree of correspondence with the predicted value of 8.4 L/mussel/h, which verified the practicability of this optimum strategy. Our findings contribute to our understanding of the context‐specific ecosystem engineering provided by mussels in natural systems, and also provides a framework for optimizing conditions for the applied use of mussels as biological filters.

Unprecedented rates of introduction and spread of non-native species pose burgeoning challenges to biodiversity, natural resource management, regional economies, and human health. Current biosecurity efforts are failing to keep pace with globalization, revealing critical gaps in our understanding and response to invasions. Here, we identify four priority areas to advance invasion science in the face of rapid global environmental change. First, invasion science should strive to develop a more comprehensive framework for predicting how the behavior, abundance, and interspecific interactions of non-native species vary in relation to conditions in receiving environments and how these factors govern the ecological impacts of invasion. A second priority is to understand the potential synergistic effects of multiple co-occurring stressors— particularly involving climate change—on the establishment and impact of non-native species. Climate adaptation and mitigation strategies will need to consider the possible consequences of promoting non-native species, and appropriate management responses to non-native species will need to be developed. The third priority is to address the taxonomic impediment. The ability to detect and evaluate invasion risks is compromised by a growing deficit in taxonomic expertise, which cannot be adequately compensated by new molecular technologies alone. Management of biosecurity risks will become increasingly challenging unless academia, industry, and governments train and employ new personnel in taxonomy and systematics. Fourth, we recommend that internationally cooperative biosecurity strategies consider the bridgehead effects of global dispersal networks, in which organisms tend to invade new regions from locations where they have already established. Cooperation among countries to eradicate or control species established in bridgehead regions should yield greater benefit than independent attempts by individual countries to exclude these species from arriving and establishing.

Identification of ecosystem services, i.e. the contributions that ecosystems make to human well-being, has proven instrumental in galvanising public and political support for safeguarding biodiversity and its benefits to people. Here we synthe-sise the global evidence on ecosystem services provided and disrupted by freshwater bivalves, a heterogenous group of >1200 species, including some of the most threatened (in Unionida) and invasive (e.g. Dreissena polymorpha) taxa globally. Our systematic literature review resulted in a data set of 904 records from 69 countries relating to 24 classes of provision-ing (N = 189), cultural (N = 491) and regulating (N = 224) services following the Common International Classification of Ecosystem Services (CICES). Prominent ecosystem services included (i) the provisioning of food, materials and medicinal products, (ii) knowledge acquisition (e.g. on water quality, past environments and historical societies), ornamental and other cultural contributions, and (iii) the filtration, sequestration, storage and/or transformation of biological and physico-chemical water properties. About 9% of records provided evidence for the disruption rather than provision of ecosystem services. Synergies and trade-offs of ecosystem services were observed. For instance, water filtration by freshwater bivalves can be beneficial for the cultural service 'biomonitoring', while negatively or positively affecting food consumption or human recreation. Our evidence base spanned a total of 91 genera and 191 species, dominated by Unionida (55% of records, 76% of species), Veneroida (21 and 9%, respectively; mainly Corbicula spp.) and Myoida (20 and 4%, respectively; mainly Dreissena spp.). About one third of records, predominantly from Europe and the Amer-icas, related to species that were non-native to the country of study. The majority of records originated from Asia (35%), with available evidence for 23 CICES classes, as well as Europe (29%) and North America (23%), where research was largely focused ...
