The effect of stimulus number on the stability of responses for an extensive heat pain test

Background.?The use of relatively lower stimulus presentation numbers in quantitative sensory testing may influence the computation accuracy of participants’ discriminability. The minimum trial number for obtaining a stabilized participant discrimination ability was determined.

Materials and methods.?Twelve participants’ ability to discriminate between noxious heat stimuli pairs (45°C/46°C, 46°C/47°C, and 47°C/48°C) was assessed using a six-category confidence rating scale. Heat stimuli were administered to the forearm. Two conditions with presentation numbers of 17 trials per stimulus (representing the median number of trials in previous studies) and 40 trials per stimulus (used in a previous study with a similar protocol) were used.

Results and discussion.?Participants’ discriminability stabilized at approximately the 20th trial based on the lowest frequency of indeterminate and non-model conforming results under both conditions. A simple linear regression model showed a statistically significant positive relationship between discriminability for the two conditions (slope?=?0.65, p?<?0.001; constant?=?0.33, p?=?0.02; r^2?=?0.51). As a rule of thumb, approximately 20 trials per stimulus intensity could be used to obtain a stabilized discriminability outcome.     

National interests and international collaboration: tensions and ambiguity among Finns towards usages of tissue samples

Recent trends in biobanking indicate that the practices associated with the collection and use of human tissue samples and related health information are increasingly becoming premised on networks of biobanks. These networks and partnerships often involve international collaborations, as well as public–private partnerships. This article reports on the results of a study of people's attitudes towards biobanking and the biomedical use of tissue samples in Finland. Three approaches were used to study these attitudes: a population-based survey, focus group interviews among members of patient organizations and short interviews with research participants. In particular, we look at the attitudes of respondents in these three studies towards the use of tissue samples and use them as a catalyst to discuss two dimensions of biomedical research: public/private and domestic/international. Our discussion highlights how notions of value related to the use of tissue samples vary and provide contrasting perspectives and ambiguity that people may have towards various types of research partnerships and the benefits that may arise from them.     

A new technique for obtaining mitotic chromosome spreads from fishes in the field

This study presents an adaptation of current methodologies for preparing mitotic chromosomes from fishes, optimized for use in the field. The high-quality preparations obtained using this modified methodology is suitable for subsequent chromosomal analysis. Importantly, this method is particularly useful when specimen collection sites are far from research laboratories or when researchers are working with highly sensitive species that do not survive long outside of their natural habitats.     

To separate is to sustain: Sacrifice and national belonging among East Timorese in West Timor

This paper examines the way the notion of sacrifice is used to reclaim national belonging and entitlements. I particularly focus my discussion on pro‐Indonesian East Timorese who left East Timor and decided to stay in West Timor after their historic referendum. The East Timorese experience of violent colonisation, military occupation, family breakdown and separation might help explain the existence of their sacrificial narratives. But I argue that such narratives evoke life histories and shared memories, which, in turn, entail the intention of displaced East Timorese to maintain an intimate relationship with their homeland and ensure a better future for their society.     

Bacterial taxa–area and distance–decay relationships in marine environments

The taxa–area relationship (TAR) and the distance–decay relationship (DDR) both describe spatial turnover of taxa and are central patterns of biodiversity. Here, we compared TAR and DDR of bacterial communities across different marine realms and ecosystems at the global scale. To obtain reliable global estimates for both relationships, we quantified the poorly assessed effects of sequencing depth, rare taxa removal and number of sampling sites. Slope coefficients of bacterial TARs were within the range of those of plants and animals, whereas slope coefficients of bacterial DDR were much lower. Slope coefficients were mostly affected by removing rare taxa and by the number of sampling sites considered in the calculations. TAR and DDR slope coefficients were overestimated at sequencing depth <4000 sequences per sample. Noticeably, bacterial TAR and DDR patterns did not correlate with each other both within and across ecosystem types, suggesting that (i) TAR cannot be directly derived from DDR and (ii) TAR and DDR may be influenced by different ecological factors. Nevertheless, we found marine bacterial TAR and DDR to be steeper in ecosystems associated with high environmental heterogeneity or spatial isolation, namely marine sediments and coastal environments compared with pelagic ecosystems. Hence, our study provides information on macroecological patterns of marine bacteria, as well as methodological and conceptual insights, at a time when biodiversity surveys increasingly make use of high‐throughput sequencing technologies.     

Between nationalism and civilizationism: the European populist moment in comparative perspective

This paper argues that the national populisms of Northern and Western Europe form a distinctive cluster within the wider north Atlantic and pan-European populist conjuncture. They are distinctive in construing the opposition between self and other not in narrowly national but in broader civilizational terms. This partial shift from nationalism to “civilizationism” has been driven by the notion of a civilizational threat from Islam. This has given rise to an identitarian “Christianism”, a secularist posture, a philosemitic stance, and an ostensibly liberal defence of gender equality, gay rights, and freedom of speech. The paper highlights the distinctiveness of this configuration by briefly comparing the national populisms of Northern and Western Europe to the Trump campaign and to the national populisms of East Central Europe. It concludes by specifying two ways in which the joining of identitarian Christianism with secularist and liberal rhetoric challenges prevailing understandings of European national populism.     

The rise of research on futures in ecology: rebalancing scenarios and predictions

Concern about the ecological consequences of global change has increasingly stimulated ecologists to examine the futures of ecological systems. Studying futures is not only a crucial element of the interaction between science, management and decision making , but also a critical research challenge per se , especially because futures cannot be observed or experimented on. In addition, researchers can encounter methodological and theoretical difficulties, which make interpretations and predictions problematic. In the literature which deals with futures of ecological systems two main lines of research can be distinguished: a predictive approach, which dominates the literature, can be contrasted with a rarer number of studies that elaborate potential scenarios for ecological systems. Scenario approaches currently concern mainly contacts with stakeholders or decision makers, or the use of climate scenarios to derive projections about ecological futures. We argue that a new direction for ecological futures research could be explored by using ecological scenarios in combination with predictive models to further fundamental ecological research, in addition to enhancing its applied value.     

National numbers for transnational relations? Challenges of integrating quantitative methods into research on transnational labour market relations

Abstract

Research into transnational labour markets requires qualitative as well as quantitative research data. Yet there is little discussion on how to integrate quantitative methods into existing – overwhelmingly qualitative?– approaches to transnational research. This article seeks to identify some of the key challenges for the use of quantitative methods in research on transnational social relations. Selected problems regarding (1) sampling procedures and (2) questionnaire design are discussed using examples from emergent transnational labour markets in the Central European region, arguing that a transnational perspective necessitates a mixed-methods design. The ethnosurvey is identified as a starting point for an appropriate research design. Multi-sited ethnography and respondent-driven sampling methods are discussed as crucial complementing elements of transnational mixed-methods research.
