Can I Have Permission to Leave the House? Return Migration and the Transfer of Gender Norms

Does international return migration transfer gender norms? Focusing on Jordan, an Arab country where discrimination against women and emigration rates are high, this paper exploits unique data in which detailed information on female empowerment allows us to construct several measures of discriminatory social norms in Jordan on the role of women, female freedom of mobility, and female decision-making power. Controlling for both emigration and return migration selections, we find that women with a returnee family member are more likely to have internalized discriminatory gender norms than women in households with no migration experience. Further analysis shows that results are driven by returnees from conservative Arab countries, suggesting a transfer of negative norms from highly discriminatory destinations. We also show the implications of our results beyond perceptions for several economic and development outcomes, such as female labour force participation, education and fertility

Effect of pH on superoxide/ hydroperoxyl radical trapping by nitrones: an EPR/kinetic study

International audienceThe pH dependence of the apparent rate constant kTap for O2-./HO2. trapping by four nitrones was examined. In each case, kinetic curves were obtained after treatment of EPR spectra of the spin adduct formed using both singular value decomposition and pseudo-inverse deconvolution methods. Modelling these curves led to evaluate kTap at various pH values. Analysis of the pH dependence of kTap permitted the determination of the rate constants for the spin trapping of O2-. and of HO2. separately. Whatever the nitrone, our results clearly show that the EPR signals of the nitrone/superoxide spin adducts observed in aqueous media were essentially due to the trapping of the protonated species HO2

Using conversation analysis in data-driven aviation training with large-scale qualitative datasets

This paper contributes to a growing body of work related to the Conversation Analytic Role-play Method (CARM) by studying the primary flight instruction environment to create training interventions related to radio communications and flight instruction practices. Framed in the context of conversation analysis, an approach to the detailed analysis of naturally occurring interaction, the large-scale, long-duration qualitative audio/video data collection and coding methodology is discussed, followed by trends identified in the ongoing study. The concept of CARM “trainables” are discussed with examples. The study shows that large-scale qualitative datasets may be leveraged to produce valuable data-driven training interventions

International Migration: Driver of Political and Social Change?

This paper focuses on the impact of international migration on the transfer of political and social norms. Exploiting recent and unique data on Morocco, it explores whether households with return and current migrants bear different political preferences and behaviours than non-migrant families. Once controlling for the double selection into emigration and return migration, findings suggest that having a returnee in the household increases the demand for political and social change, driven by returnees mostly from Western European countries, who have been exposed to more democratic norms at destination. However, we find a negative impact of having a current migrant on the willingness to change of the left-behind household, driven by migrants to non-West countries, where the quality of political and social institutions are lower. Our results are robust to also controlling for destination selectivity. Finally, findings suggest that migration not only affect political attitudes but also actual behaviour: regions with higher returnee shares have had greater participation rates in the 2011 political elections

Trans-1,2-disiloxybenzocyclobutene, an adequate partner for the auto-oxisation: EPR/spin trapping and theoretical studies

International audienceThe auto-oxidation of trans-1,2-disiloxybenzocyclobutene was found to be very efficient, giving endoperoxide in quantitative yield. Each step of the mechanism of spin-forbidden addition of triplet oxygen O2 was studied by both EPR/spin trapping and theoretical studies

PFOS induces behavioral alterations, including spontaneous hyperactivity that is corrected by dexamfetamine in zebrafish larvae

Perfluorooctane sulfonate (PFOS) is a widely spread environmental contaminant. It accumulates in the brain and has potential neurotoxic effects. The exposure to PFOS has been associated with higher impulsivity and increased ADHD prevalence. We investigated the effects of developmental exposure to PFOS in zebrafish larvae, focusing on the modulation of activity by the dopaminergic system. We exposed zebrafish embryos to 0.1 or 1 mg/L PFOS (0.186 or 1.858 µM, respectively) and assessed swimming activity at 6 dpf. We analyzed the structure of spontaneous activity, the hyperactivity and the habituation during a brief dark period (visual motor response), and the vibrational startle response. The findings in zebrafish larvae were compared with historical data from 3 months old male mice exposed to 0.3 or 3 mg/kg/day PFOS throughout gestation. Finally, we investigated the effects of dexamfetamine on the alterations in spontaneous activity and startle response in zebrafish larvae. We found that zebrafish larvae exposed to 0.1 mg/L PFOS habituate faster than controls during a dark pulse, while the larvae exposed to 1 mg/L PFOS display a disorganized pattern of spontaneous activity and persistent hyperactivity. Similarly, mice exposed to 0.3 mg/kg/day PFOS habituated faster than controls to a new environment, while mice exposed to 3 mg/kg/day PFOS displayed more intense and disorganized spontaneous activity. Dexamfetamine partly corrected the hyperactive phenotype in zebrafish larvae. In conclusion, developmental exposure to PFOS in zebrafish induces spontaneous hyperactivity mediated by a dopaminergic deficit, which can be partially reversed by dexamfetamine in zebrafish larvae

Rapid and non-destructive method to assess in the vineyardgrape berry anthocyanins under different seasonal andwater conditions

Abstract Background and Aims: Monitoring of anthocyanins (Anth) in winegrape (Vitis vinifera L.) is fundamental for the production of top-quality red wines. This work was aimed at testing a new fluorescence-based sensor for Anth detection in the vineyard. Significance of the Study: The present study showed a new important innovative technology for viticulture. The sensor evaluation of the large spatial and temporal heterogeneity in Anth accumulation can be useful as support parameter in the harvest date decision or for vineyard zoning of phenolic maturity. Methods and Results: Anth in grape (cv. Aleatico) bunches attached to the vine were monitored non-destructively in the field using a fluorescence-based sensor during the 2008 and 2009 seasons and under different water regimes. The ANTHRG index = log(far-red-fluorescenceR/far-red-fluorescenceG), with fluorescence signals excited with red (R) and green (G) light, was inversely correlated through an exponential function (r2 = 0.875) to the Anth concentration derived from the HPLC analysis of berry skin extracts. ANTHRG was effective in detecting the earlier ripening process in 2009 with respect to 2008 and differences in the Anth accumulation between seasons and in relation to different water regimes.Water deficit imposed in 2009 enhanced Anth concentration in berries because of a reduction in berry size but also an increase of Anth biosynthesis. This effect was observed by both destructive and ANTHRG non-destructive measurements. Conclusions: Our results show that the employed fluorescence sensor represents a reliable, rapid and non-invasive tool for monitoring and determining Anth accumulation in situ

Heuristics to Improve Human Factors Performance in Aviation

This paper reviews literature related to heuristic cognitive strategies as they are used by flight crews. A review of heuristic and naturalistic cognition is presented. An example set of heuristics and cognitive biases are presented and where possible exemplified by 19 airline accidents. The paper suggests two tentative research designs which could be pursued to quantitatively study heuristics and its impact on aviation decision making. The paper concludes that aviation pilot training would benefit by introducing pilots to the concepts and constructs of heuristic thinking

Collaborative Audio Transcription and Repair as a Method for Novice Pilots to Learn Approach Briefing Crew Resource Management (CRM) Skills

The growth of aviation in scope, scale, and complexity increases the demands for student learning, including crew resource management (CRM) skills. Instructor facilitated methods have proven effective for CRM skill learning. This study investigated a method of collaborative audio transcription and repair based learning (CTRBL) offering the potential for reduced demand upon instructor resources for CRM learning. The theorybased CTRBL method was used in this study as a way for novice pilots to learn the CRM skill of conducting a crew approach briefing with a focus on risk mitigation. Learning methods used to develop the CTRBL method were drawn from facilitated scenario-based training in aviation, instructional methods in language learning, and discourse analysis in aviation. The CTRBL method effectiveness was evaluated by a quasi-experimental method using 42 participants formed into 21 dyadic groups. The results suggest that CTRBL is a manageable, independent student activity that is perceived by learners to be nearly as enjoyable as comparable ground-based CRM learning methods. Participants self-rated their post-treatment crew briefings higher than their pre-treatment briefings, and subject matter experts rated post-treatment crew briefings higher than pre-treatment briefings, suggesting the CTRBL method resulted in learning. Recommendations are made for future applications and research of CTRBL

Improving Instructor Quality using the Conversation Analytic Role-play Method (CARM)

The audience will learn about Stokoe’s Conversation Analytic Role-play Method (CARM) (http://www.carmtraining.org) and how it has been used to study and improve talk-in-interaction in professional settings. CARM is a proven, research-based methodology which collects large volumes of recorded audio and/or video particular to a professional setting and then uses detailed transcription and conversation analysis to identify systematic patterns of interaction and problems thereof. Actual excerpts from the dataset are appropriately anonymized and used by facilitators in a workshop setting to create authentic role-play. The presentation will explain how CARM has been applied to help improve flight instructor teaching quality (see JAAER, 2017, 26 (1), Tuccio & Nevile). This research includes the collection and coding of over 100 hours of flight instruction video and audio by consenting pilots, and the subsequent identification of “trainable” interactional moments useful to current and prospective flight instructors. The audience will interactively participate in exemplary CARM training as it has been used at FAA Safety Team seminars. A small excerpt from one trainable follows. At line 21, a check instructor on an instrument stage check asks the student if they will get “positive sensing.” The long pause, throat clearing, and prosody of lines 22-24 make salient a misunderstanding. Through workshop role-play and discussion, instructors can identify the problem and decide how they may avoid a similar pitfall. 21 *INS: no:w are we gonna get (.) positive sensing, (.) on the CDI?22 (1.1)23 *STU: ((clears throat)) 24 *STU: positive sensing? 25 (0.5)26 *INS: yeah
