International Society for Prenatal Diagnosis 2022 debate 3—Fetal genome sequencing should be offered to all pregnant patients

Prenatal trio exome sequencing (ES) has become integrated into the care for pregnant women when the fetus has structural anomalies. Details regarding optimizing indications for prenatal exome sequencing, its detection rates with different categories of fetal anomalies, and principles of interpretation of pathogenicity of sequence variants are still under investigation. However, there is now growing consensus about its benefits for finding the cause of fetal structural anomalies. What is not established, is whether exome or genome sequencing (GS) has a place in the care of all pregnant women. This report is a summary of the debate on this topic at the 26th International Conference on Prenatal Diagnosis and Therapy. Both expert debaters considered the advantages and disadvantages. Advantages include the ability to diagnose serious childhood conditions without a prenatally observable phenotype, which creates the potential of early treatments. Disadvantages include difficulties with variant classification, counseling complexities, healthcare cost, and the burden on healthcare systems and families, in particular with the discovery of adult-onset disorders or variants of uncertain significance. Although both debaters weighed the balance of these conflicting arguments differently, they agreed that more research is needed to further explore the clinical utility and ethical aspects of GS for all pregnant women.     

Drivers of agricultural sustainability in developing countries: a review

Agricultural development has been an effective instrument for poverty alleviation and economic development in developing countries over the latter half of the twentieth century, and over 80 % of rural people globally still depend on agriculture for their living. However, issues such as water availability, land degradation and an increasing dependence on chemical fertilisers and pesticides continue to be on-going threats to sustainable agricultural development. These threats are being driven by the pressing need to ensure food security in the face of rapidly growing and urbanising populations. Developing countries will therefore continue to need improved methods for planning sustainable agricultural development. This paper presents a review of agricultural sustainability assessment in developing countries. The review highlights some of the key weaknesses that persist in sustainability assessment and the need to consider not only indicators of sustainability but also the drivers that influence indicator behaviour. We argue that without a good understanding of the drivers of sustainability and their systemic relationships to indicators, sustainability assessments run the risk of focusing on symptoms without addressing underlying causes of adverse indicator trends. Drivers of agricultural sustainability in developing countries encompass a range of demographic, natural, socio-economic, political, institutional and management factors. Understanding these and their relationships to sustainability indicators is needed in order to develop agricultural development policy that supports sustainability. The paper presents a conceptual framework for guiding systemic agricultural sustainability assessment and agricultural development planning in developing countries that includes both sustainability indicators and drives, and considers the broad relationships between them.     

The contribution of non‐timber forest products towards sustainable rural development: The case of Candelilla wax from the Chihuahuan Desert in Mexico

The promotion of development projects based on the commercialization of non‐timber forest products has increased in recent decades, showing a positive contribution to rural development; yet it has led to controversial approaches in resource preservation. This paper examines the case of Candelilla wax from the Chihuahuan Desert in northern Mexico, identifying its potential contribution to poverty alleviation in marginal areas, and its unique opportunity to access potential markets of a wide variety of industries all around the world. In this paper, the authors base their analysis on three main aspects: social, economic and environmental. Potential benefits that could be obtained from the collaboration of private institutions, development organizations, policymakers and rural producers through integrated rural development projects are featured.     

Task type as a moderator of positive/negative feedback effects on motivation and performance: A regulatory focus perspective

Applying Higgins' regulatory focus theory, we hypothesized that the effect of positive/negative feedback on motivation and performance is moderated by task type, which is argued to be an antecedent to situational regulatory focus (promotion or prevention). Thus, first we demonstrated that some tasks (e.g., tasks requiring creativity) are perceived as promotion tasks, whereas others (e.g., those requiring vigilance and attention to detail) are perceived as prevention tasks. Second, as expected, our tests in two studies of the moderation hypothesis showed that positive feedback increased self‐reported motivation (meta‐analysis across samples: N = 315, d = 0.43) and actual performance (N = 55, d = 0.67) among people working on promotion tasks, relative to negative feedback. Positive feedback, however, decreased motivation (N = 318, d = ?0.33) and performance (N = 55, d = ?0.37) among individuals working on prevention tasks, relative to negative feedback. These findings suggest that (a) performance of different tasks can affect regulatory focus and (b) variability in positive/negative feedback effects can be partially explained by regulatory focus and task type.

Adolescents’ environmental worldview and personality: An explorative study

There is a growing interest among scholars in instruments based on environmental worldview. Several studies have used instruments of this kind to compare groups of children or to assess the impact of environmental education initiatives (EEIs) on children’s environmental worldview. When using scales of this nature, it is important to control for factors that might blur the true impact of EEIs. One such factor - and which may have been neglected - is personality. This study (n = 957) examines the link between environmental worldview of Belgian adolescents (as measured by the New Environmental Paradigm scale for children - NEP) and their personality (as measured by the Hierarchical Personality Inventory for Children - HiPIC). The results show that adolescents who are willing to take responsibility for their actions and who feel in control over the outcomes of their decisions are more likely to have an ecocentric worldview. Furthermore, this study demonstrates that, for Belgian adolescents, egocentrism and ecocentrism are opposite conceptions. All correlations were, however, small and showed no deterministic pattern in the relationship between adolescents’ environmental worldview and personality, indicating that worldviews are not stable or innate characteristics within individuals, but can be influenced by interactions between the individual and its context. Personality traits explained only a very small part of the variation in adolescents’ environmental worldview (.7%), suggesting that they are unlikely to blur the impact of EEIs in worldview-based assessment. This is an important finding as it indicates that the results of studies showing differences in the environmental worldview of different groups of respondents or changes in their environmental worldview as a result of taking part in an EEI are not artefacts of non-control for personality and that they may, therefore, reflect genuine differences, changes or impacts.     

Proximate causes of natal dispersal in female yellow-bellied marmots, Marmota flaviventris

We investigated factors influencing natal dispersal in 231 female yearling yellow-bellied marmots (Marmota flaviventris) using comprehensive analysis of 10 years (1983-1993) of radiotelemetry and 37 years (1963-1999) of capture-mark-recapture data. Only individuals whose dispersal status was verified, primarily by radiotelemetry, were considered. Univariate analyses revealed that six of the 24 variables we studied significantly influenced dispersal: dispersal was less likely when the mother was present, amicable behavior with the mother and play behavior were more frequent, and spatial overlap was greater with the mother, with matriline females, and with other yearling females. Using both univariate and multivariate analyses, we tested several hypotheses proposed as proximate causes of dispersal. We rejected inbreeding avoidance, population density, body size, social intolerance, and kin competition as factors influencing dispersal. Instead, our results indicate that kin cooperation, expressed via cohesive behaviors and with a focus on the mother, influenced dispersal by promoting philopatry. Kin cooperation may be an underappreciated factor influencing dispersal in both social and nonsocial species.     

The burden of proof in trade disputes and the environment

The WTO leaves discretion over environmental policies to its members, but requests that a fundamental non-discrimination principle is respected: National Treatment (NT). The provision seeks to prevent protectionist use of domestic policy instruments, requesting that when an imported product is sufficiently similar to a domestic product, they are treated identically. WTO adjudicators will often face severe informational problems in environmental disputes. Important for the practical implementation of NT is therefore the allocation of the burden of proof (BoP). This paper highlights basic implications of the BoP for the occurrence of judicial errors, for the environment and for welfare, using a setting where NT serves its intended role of supporting negotiated tariff liberalization. The paper suggests that NT may indeed constrain environmental policies, but that this may be desirable from an efficiency point of view. Also, BoP rules that benefit the environment may not benefit global welfare, and conversely.
