What can inactivity (in its various forms) reveal about affective states in non-human animals? A review

Captive/domestic animals are often described as inactive, with the implicit or explicit implication that this high level of inactivity is a welfare problem. Conversely, not being inactive enough may also indicate or cause poor welfare. In humans, too much inactivity can certainly be associated with either negative or positive affective states. In non-human animals, however, the affective states associated with elevated or suppressed levels of inactivity are still not well understood. Part of the complexity is due to the fact that there are many different forms of inactivity, each likely associated with very different affective states. This paper has two aims. One is to identify specific forms of inactivity that can be used as indicators of specific affective states in animals. The other is to identify issues that need to be resolved before we could validly use the remaining, not yet validated forms of inactivity as indicators of affective state. We briefly discuss how inactivity is defined and assessed in the literature, and then how inactivity in its various forms relates to affective (either negative or positive) states in animals, basing our reasoning on linguistic reports of affective states collected from humans displaying inactivity phenotypically similar to that displayed by animals in similar situations, and, when possible, on pharmacological validation. Specific forms of inactivity expressed in response to perceived threats (freezing, tonic immobility, and hiding) appear to be, to date, the best-validated indicators of specific affective states in animals. We also identify a number of specific forms of inactivity likely to reflect either negative (associated with ill-heath, boredom-like, and depression-like conditions), or positive states (e.g. ‘sun-basking’, post-consummatory inactivity), although further research is warranted before we could use those forms as indicators of the affective states. We further discuss the relationship between increased inactivity and affective states by presenting misleading situations likely to yield wrong conclusions. We conclude that more attention should be paid to inactivity in animal welfare studies: specific forms of inactivity identified in this paper are, or have the potential to be, useful indicators of affective (welfare) states in animals

Ni crisis ni panaceas: dinámicas y transformaciones de los sistemas partidarios en América Latina

A nivel global, tanto en la literatura especializada como en el debate público, la desafección ciudadana hacia la cosa pública, el debilitamiento de los partidos políticos y el aumento de la abstención contribuyeron a asentar la idea de una crisis de los sistemas de partidos y de la democracia. Diferentes indicadores darían cuenta de esta crisis: el desarraigo social de los partidos que consagró el modelo del partido cartel (Katz y Mair 1995); el declive de la militancia (Van Biezen, Mair y Poguntke 2012; Whiteley 2011); la erosión de las estructuras partidarias tradicionales capturadas por el lobby corporativo (Crouch 2004 [2014], 112) o la tecnocracia; la pérdida de capacidad de los líderes para construir partidos programáticos que expresaran identidades políticas duraderas (Cheresky 2006; Dalton 2004; Luna 2014b); o su incapacidad para responder con una mayor deliberación interna a los desafíos de la representación política (Accetti y Wolkenstein 2017).Fil: Alenda, Stéphanie.

Host Decoy Trap (HDT) with cattle odour is highly effective for collection of exophagic malaria vectors

Background: As currently implemented, malaria vector surveillance in sub-Saharan Africa targets endophagic and endophilic mosquitoes, leaving exophagic (outdoor blood feeding) mosquitoes underrepresented. We evaluated the recently developed host decoy trap (HDT) and compared it to the gold standard, human landing catch (HLC), in a 3x3 Latin square study design outdoors in western Kenya. HLCs are considered to represent the natural range of Anopheles biting-behaviour compared to other sampling tools, and therefore, in principle, provide the most reliable profile of the biting population transmitting malaria. The HDT incorporates the main host stimuli that attract blood meal seeking mosquitoes and can be baited with the odours of live hosts. Results: Numbers and species diversity of trapped mosquitoes varied significantly between HLCs and HDTs baited with human (HDT-H) or cattle (HDT-C) odour, revealing important differences in behaviour of Anopheles species. In the main study in Kisian, the HDT-C collected a nightly mean of 43.2 (95% CI; 26.7-69.8) Anopheles, compared to 5.8 (95% CI; 4.1-8.2) in HLC, while HDT-H collected 0.97 (95% CI; 0.4-2.1), significantly fewer than the HLC. Significantly higher proportions of An. arabiensis were caught in HDT-Cs (0.94 ± 0.01; SE) and HDT-Hs (0.76 ± 0.09; SE) than in HLCs (0.45 ± 0.05; SE) per trapping night. The proportion of An. gambiae s.s. was highest in HLC (0.55 ±0.05; SE) followed by HDT-H (0.20 ± 0.09; SE) and least in HDT-C (0.06 ± 0.01; SE). An unbaited HDT placed beside locales where cattle are usually corralled overnight caught mostly An. arabiensis with proportions of 0.97 ± 0.02 and 0.80 ± 0.2 relative to the total anopheline catch in the presence and absence of cattle, respectively. A mean of 10.4 (95% CI; 2.0-55.0) Anopheles/night were trapped near cattle, compared to 0.4 (95% CI; 0.1-1.7) in unbaited HDT away from hosts. Conclusions: The capability of HDTs to combine host odours, heat and visual stimuli to simulate a host provides the basis of a system to sample human- and cattle-biting mosquitoes. HDT-C is particularly effective for collecting An. arabiensis outdoors. The HDT offers the prospect of a system to monitor and potentially control An. arabiensis and other outdoor-biting mosquitoes more effectively

School -Based Reflection (Sbr): Engaging External Accountability Using Critical Reflection

195 p.Thesis (Ph.D.)--University of Illinois at Urbana-Champaign, 2008.The study addressed two questions: What are the challenges of moving SBR from theory to practice? and To what extent and in what ways did the SBR process constitute a meaningful and useful school-based evaluation process? To answer these questions, the study used qualitative methods to portray the complexity and uniqueness of implementing SBR in a specific context. Findings from this study demonstrated the challenges in implementing a democratic and culturally responsive school-based evaluation approach, how school-based evaluation can be used to assist schools in building internal capacity to meet external demands by thinking evaluatively, and how teachers can help each other with improving teaching and learning.U of I OnlyRestricted to the U of I community idenfinitely during batch ingest of legacy ETD
