Dealing with diversity: State strategies on ethnic minority management in Southeast Asia

Southeast Asia’s ethnic, political and cultural diversity continues to pose major policy and governance hurdles in enforcing a common community born out of the post-colonial nationalist baggage of almost all the region’s countries. ASEAN’s “non-interference” clause gives leeway to each member state to respond to its ethnic diversity with nation-building projects through exclusionary governance. With this leeway, each Southeast Asian country’s nation-building policieslegitimize a particular, existing ethno-nationalist or “ethno-religious” majority at the expense of democratic accountability. This study proposes a preliminary quantitative model which uses regression analysis to compare Southeast Asian countries’ data on their religious and ethnic populations. The initial model categorizes the types of minority management strategies depending on their respective ethnic heterogeneity. This study hypothesizes that a) states with moreethnically homogenous populations will have more exclusionary and violent state policies towards minorities, while b) states with more heterogeneous populations will have fewer exclusionary and violent policies. The results indicate a moderate causality between the two variables and may be correlated with additional variables such as the level of democratic consolidation (as tabulated by the Polity IV democratic index) and the centralized structure of governance

Disentangling the Effect of Valence and Arousal on Judgments Concerning Moral Transgressions

An increasing body of research has investigated the effect of emotions on judgments concerning moral transgressions. Yet, few studies have controlled for arousal levels associated with the emotions. High arousal may affect moral processing by triggering attention to salient features of transgressions, independently of valence. Therefore previously documented differences in effects of negative and positive emotions may have been confounded by differences in arousal. We conducted two studies to shed light on this issue. In Study 1 we developed a questionnaire including vignettes selected on the basis of psychometrical properties (i.e., mean ratings of the actions and variability). This questionnaire was administered to participants in Study 2, after presenting them with selected pictures inducing different valence but equivalent levels of arousal. Negative pictures led to more severe moral judgments than neutral (p = .054, d = 0.60) and positive pictures (p = .002, d = 1.02), for vignettes that were not associated with extreme judgments. In contrast, positive pictures did not reliably affect judgments concerning such vignettes. These findings suggest that the observed effects of emotions cannot be accounted for by an increase in attention linked to the arousal which accompanies these emotion

Implications of COVID-19 on Progress in the UN Conventions on Biodiversity and Climate Change

2020 was to be a landmark year for setting targets to stop biodiversity loss and prevent dangerous climate change. However, COVID-19 has caused delays to the 15th Conference of the Parties (COP) of the UN Convention on Biological Diversity and the 26th COP of the UN Framework Convention on Climate Change. Negotiations on the Global Biodiversity Framework and the second submission of Nationally Determined Contributions under the Paris Agreement were due to take place at these COPs. There is uncertainty as to how the COVID-19 disruption will affect the negotiations, whether parties will pursue more ambitious actions or take a weaker stance on issues. Our policy analysis shows there are broad opportunities for climate and biodiversity frameworks to better respond to COVID-19, by viewing future pandemics, biodiversity loss, and climate change as interconnected problems. Importantly, there needs to be greater focus on agriculture and food systems in discussions, establishing safeguards for carbon markets, and implementing nature-based solutions in meeting the Paris Agreement goals. We can no longer delay action to address the biodiversity and climate emergencies, and accelerating sustainable recovery plans through virtual spaces may help keep discussions and momentum before the resumption of in-person negotiations

Human exceptional longevity: transcriptome from centenarians is distinct from septuagenarians and reveals a role of Bcl‐xL in successful aging

Centenarians not only enjoy an extraordinary aging, but also show a compression of morbidity. Using functional transcriptomic analysis of peripheral blood mononuclear cells (PMBC) we identified 1721 mRNAs differentially expressed by centenarians when compared with septuagenarians and young people. Sub‐network analysis led us to identify Bcl ‐ xL as an important gene up‐regulated in centenarians. It is involved in the control of apoptosis, cellular damage protection and also in modulation of immune response, all associated to healthy aging. Indeed, centenarians display lower plasma cytochrome C levels, higher mitochondrial membrane potential and also less cellular damage accumulation than septuagenarians. Leukocyte chemotaxis and NK cell activity are significantly impaired in septuagenarians compared with young people whereas centenarians maintain them. To further ascertain the functional role of Bcl‐ xL in cellular aging, we found that lymphocytes from septuagenarians transduced with Bcl‐xL display a reduction in senescent‐related markers. Finally, to demonstrate the role of BcL‐xL in longevity at the organism level, C. elegans bearing a gain of function mutation in the BcL‐xL ortholog ced‐9, showed a significant increase in mean and maximal life span. These results show that mRNA expression in centenarians is unique and reveals that BcL‐ xL plays an important role in exceptional aging

Photography-based taxonomy is inadequate, unnecessary, and potentially harmful for biological sciences

The question whether taxonomic descriptions naming new animal species without type specimen(s) deposited in collections should be accepted for publication by scientific journals and allowed by the Code has already been discussed in Zootaxa (Dubois & Nemésio 2007; Donegan 2008, 2009; Nemésio 2009a–b; Dubois 2009; Gentile & Snell 2009; Minelli 2009; Cianferoni & Bartolozzi 2016; Amorim et al. 2016). This question was again raised in a letter supported by 35 signatories published in the journal Nature (Pape et al. 2016) on 15 September 2016. On 25 September 2016, the following rebuttal (strictly limited to 300 words as per the editorial rules of Nature) was submitted to Nature, which on 18 October 2016 refused to publish it. As we think this problem is a very important one for zoological taxonomy, this text is published here exactly as submitted to Nature, followed by the list of the 493 taxonomists and collection-based researchers who signed it in the short time span from 20 September to 6 October 2016
