Archaeolinguistics of the languages of the Andes
No full textThis chapter discusses aspects of the prehistoric language dynamics of the Andes of South America. Featuring more than one hundred languages that belong to more than thirty distinct lineages, including a high number of isolates, the linguistic landscape of the Andes is fractal and complex, and diversity was likely even higher in pre-Columbian times. Our approach departs from observations on the language geography of the Andes on the regional level. We believe that patterns at this scale reflect qualitatively similar linguistic and demographic processes which also had occurred earlier in prehistory, often repeatedly. The language geography and language dynamics of the Andes articulate with research in archaeology and molecular anthropology that in many cases attest to similar processes, allowing us to conceive of the interface between linguistics, archaeology, and molecular anthropology in new ways beyond language expansion and its non-linguistic correlates
Hinders for Eco-friendly Media Selection
No full textThis study shows that, despite organizations claiming to care for the green environment through documented environmental policies, marketing communication such as advertising media selection does not seem to be much guided by green environmental concerns. Problems with consistency and control thus seem to exist between companies’ ideas/decisions (documented environmental policies) and their actions (advertising media selection), causing the need for justification and/or hypocrisy. This study adds to prior research on the non-use of models in practice by showing that the non-use of models also exists among marketing managers when selecting advertising media for marketing communication purposes. It was found that 64 percent of the marketing managers do not make use of media selection models. In the attempt to investigate differences in the factors guiding media selection between marketing managers who use media selection models (users) and those who do not use any model (non-users), it was found that the users take a medium’s eco-friendly characteristics less into consideration than the non-users. The paper discusses that the use of models can be viewed as attempts for making more rational decisions. The findings thus suggest that rational decision-making (users) may hinder eco-friendly media selection while non-rationality (non-users) may develop more powerful organizational ideologies such as acting responsibly towards the green environment. However, this study points out a link between the use of media selection models, previous experience and rules of thumb, i.e. the users tend to make more use of previous experience and rules of thumb than the non-users. Thus, the author argues that a new approach to model use may be needed and that the media selection should not be too much influenced by the marketing managers’ previous experience and rules of thumb. Otherwise, new factors may be overlooked such as consumers’ increasing concern for the green environment in relation to consumer advertising media attitudes. Previous studies have found that current approaches to marketing planning pay too little attention to the impact of technological advances on changes in consumer media habits. Thereby the risk may exist for focusing on mainly conventional media and not selecting “new media”. The present study seems to contradict these previous findings by showing that the selection of “new media” such as media using the Internet was found among the most selected advertising media by both the users and non-users for the two communication objectives studied, i.e. brand-building and to increase sales. Thus, the results indicate that while the marketing managers adapt their media selection to changes in technological media advances they tend to overlook consumers’ increasing concern for the green environment and the environmental aspect of advertising media. The results also show differences among the marketing managers in their selection of advertising media. At the same time as the non-users tend to be more precise with the recycling of paper, they are more inclined to select paper-based media such as catalogues and brochures than the users. The users on the other hand, tend to select more electronic media such as TV, radio and cinema than the non-users. In the attempt to explain the factors guiding media selection and in particular to what extent the environmental aspect of advertising media is considered, green environmental responsibility attitudes (GERA) of the users and non-users are assessed.Media Selection; Advertising; Green Environment; Marketing Managers; Models; Green Environmental Responsibility Attitude (GERA); Rationality; Non-rationality

First ecological study of the Bawean warty pig (Sus blouchi), Indonesia; options for wildlife conservation and community education
No full textThe research involves exploring the unknown population numbers, behaviour and ecology of Bawean warty pigs by using camera trapping and line transects. The data here available are from the camera traps in protected areas, pig population numbers and habitat preferences (incl. standard descriptors, habitat assessment and Random Encounter Model (REM) analysis). Detailed information about the dataset can be found in the file 'Habitat assessment digital datasheet.xlsx'
Why we cannot always expect life history strategies to directly inform on sensitivity to environmental change
No full text<p>Speed of life and reproductive strategy form the two major axes that organize variation in life history strategies across plant and animal species. The position of a species along these axes can inform on their sensitivity to environmental change. This provides a tantalizing link between sets of traits and population responses to change, contained in a highly generalizable theoretical framework. The underlying mechanisms are assumed to be governed by life history tradeoffs at the individual level. Examples include the tradeoff between current and future reproductive success, and investing energy into growth versus reproduction. But the importance of such tradeoffs in structuring population-level responses to environmental change remains understudied. We aim to increase our understanding of the link between individual-level life history tradeoffs and the structuring of life history strategies across species, and if they link to population responses to environmental change. We find that the classical association between life history strategies and population responses to environmental change breaks down when accounting for individual-level tradeoffs and reproductive decisions. Projecting population responses to environmental change can therefore not always be inferred based on a limited set of species traits alone. We summarize our perspective and a way forward in a conceptual framework.</p>
