ABSTRACT

Resumo A catação de materiais recicláveis é uma ocupação com crescente número de trabalhadores, que encontram nela sustento diante das desigualdades socioeconômicas e do desemprego. Este artigo descreve as estratégias de resistência de mulheres catadoras que fazem parte de uma associação no Nordeste brasileiro, além da forma como elas lidaram com problemas de saúde durante a pandemia de covid-19, especialmente no que se refere aos medicamentos. Utilizamos uma abordagem quantitativa e uma etnográfica, coletando dados sociodemográficos de 13 participantes e dos medicamentos presentes em suas casas, e também realizando observação participante e entrevistas aprofundadas. Em meio à crise sanitária, foram mencionados problemas como o desemprego, as relações de gênero, a violência e os estigmas do trabalho. Se por um lado a pandemia vulnerabilizou ainda mais alguns segmentos populacionais, por outro potencializou estratégias coletivas de enfrentamento. As catadoras e a associação se organizaram para obter insumos e melhorias tanto na sede quanto no bairro. Identificamos 58 unidades de medicamentos, prescritos e obtidos principalmente na Unidade Básica de Saúde. Desses, 27,6% tinham ação sobre o sistema nervoso (analgésicos, psicolépticos e psicoanalépticos) e 17,2% sobre o sistema cardiovascular e sobre o trato alimentar e metabolismo. As catadoras desenvolveram práticas de autoatenção com os medicamentos, destacando o papel central deles no enfrentamento dos problemas de saúde.


Abstract The collection of recyclable materials is an occupation with an increasing number of workers, who find in it a livelihood in a context of socioeconomic inequalities and unemployment. This article describes resistance strategies of women collectors who are part of an association in Northeast Brazil, in addition to describing how they managed health problems during the COVID-19 pandemic, especially regarding medicines. A quantitative and an ethnographic approach were used by collecting data on sociodemographic and medicines present in the homes of 13 participants and conducting participant observation and in-depth interviews. Amid the health crisis, the participants mentioned problems such as unemployment, gender relations, violence, and work stigmas. If, on the one hand, the pandemic has further increased vulnerability for certain population segments, on the other hand, it has enhanced collective resistance strategies. The collectors of the association organized to obtain various materials and benefits both for their headquarters and their neighborhood. We identified 58 units of medicines, prescribed and obtained mainly at the Basic Health Unit. Of these, 27.6% had action on the nervous system (analgesics, psycholeptics, and psychoanaleptics) and 17.2% on the cardiovascular system and on the alimentary tract and metabolism. The collectors developed self-attention practices with the medicines highlighting their central role in facing health problems.

ABSTRACT

Introduction: Although resistance to persuasion has been of interest in psychology, relatively little research has examined how different resistance strategies can affect the strength-related features of attitudes. The current research presents a metacognitive account of two resistance strategies and their effect on attitude certainty and intentions. Specifically, we examine how the strategies of counterarguing and bolstering can differentially affect attitude certainty and intentions to act on the attitude under attack. Methods: In two experiments, we implemented a 2(Perceived Thought Type: bolster vs. counterargue) x 2(Perceived Argument Quality: weak vs. strong) between-participants design. Participants read weak or strong arguments about a counterattitudinal topic. After reporting their thoughts in response to the message topic, participants received bogus feedback regarding the nature of their thoughts (i.e., bolstering or counterarguing). Following the feedback, participants reported their attitudes and attitude certainty. Results: In Experiment 1 (N =241), participants' thoughts perceived as counterarguments elicited attitude certainty that was more sensitive to the quality of the attacking information than when thoughts were perceived as bolstering one's opinion. Experiment 2 (N = 287) replicated the effect with a different topic and demonstrated a similar pattern on intentions to act on the attacked attitude. Discussion: The research demonstrates that two relatively thoughtful strategies, bolstering and counterarguing, can play an important role in attitude certainty and intentions following a persuasion attempt.

ABSTRACT

Background: This study examined resistance strategies used by predominantly Pacific Islander young adolescents in response to offers of tobacco, e-cigarettes, and betel [areca] nuts. This study was intended to inform the development of a prevention curriculum focused on training young adolescents from the U.S.-Affiliated Pacific Islands (USAPI) on culturally appropriate strategies to resist substance use offers. Currently, very little is understood in terms of how Pacific Islander youths deal with tobacco and other substance use offers, although the use of tobacco products among Pacific Islander youths is high. Specifically, given the collectivist sociocultural orientation of the Pacific Islander communities, it is unclear whether the direct (overt) confrontational style of resistance is a viable mode of resistance for youths to practice when faced with a substance use offer. Methods: We conducted 10 focus groups with public middle school students (N = 34) from Guam, which is part of the USAPI. Results: Results suggested that, as with other communities in the U.S., the resistance strategies fall into two categories-overt/confrontational and non-confrontational resistance strategies. Overt/confrontational strategies included (a) saying "no" and (b) verbally confronting the offeror. Non-confrontational strategies included (a) avoiding or leaving the situation and (b) telling an adult. Conclusions: Our findings have implications for the development of culturally grounded interventions aimed at preventing youth tobacco and other substance use in Guam, the USAPI, and the Pacific region.

ABSTRACT

The purpose of this study was to examine, via testimonial data, resistance strategies used to thwart a sexual assault among slum-dwelling Kenyan adolescent girls (N = 678) following their participation in an empowerment self-defense program (IMpower). The majority (58.2%) of perpetrators were strangers; there were no differences in resistance strategies used between strangers versus known perpetrators (83.8% used verbal strategies, 33.2% used resistance strategies, 16.7% ran away, and 7.9% used distraction). Associations between resistance strategies and perpetrator tactics, number of assailants, location of the assault, and the presence of a bystander were also examined.

ABSTRACT

Studies focusing on the relevance or impact of a program, not just on its efficacy or effectiveness, can make important contributions to prevention science. This article documents the social validity (i.e., a construct encompassing feasibility, acceptability, and utility) of a universal substance use prevention program for early adolescents in Spain. The Mantente REAL (keepin'it REAL) program was culturally adapted to the Spanish context, implemented, and evaluated in six public middle schools in two regions of Spain. Participating teachers (N = 15), students (N = 354), and research team members (N = 6) reported on the feasibility, acceptability, and utility of the program implemented with first grade secondary school students. Qualitative and quantitative data about the program, its curriculum, and the implementation process were collected through teachers' focus groups, students' surveys, and observation forms completed by members of the research team. Mantente REAL was perceived to be a prevention program that was feasible for implementation in Spanish middle schools, although some logistics related to school structural constraints should be addressed in future implementations. The topics and activities in the curriculum were highly accepted by teachers and students, and they reported that the program was useful in teaching resistance strategies to cope with substance use and other risky situations. The findings support the social validity of the culturally adapted Mantente REAL program for early adolescents in Spain, and highlight how feedback from stakeholders involved in the implementation can improve the dissemination of effective prevention approaches.

ABSTRACT

Despite there being an abundant gender and social science research on domestic violence (DV) in Jordan, particularly during the COVID-19 pandemic, there is limited understanding and knowledge of women's resistance strategies to DV. To fill this gap, this study conducted a scoping review to synthesize and analyze 11 articles published in English-language scholarly journals between 2001 and 2021 by following the PRISMA-ScR guidelines. The databases of the University of Jordan Library, Dar Almandumah, PsycINFO, PubMed, Google Scholar, and Scopus were searched in December 2021. Our review found no scientific articles that primarily discussed Jordanian women's resistance to DV and explicate it as a secondary aim within the context of screening for the causes, consequences, and prevalence of DV. Therefore, while a few articles implicitly conceptualized women's resistance in the context of the patriarchal structure-either as tactics of physical, social, economic survival, and to protect their family and honor, or as consequences of DV-no article provided an explicit definition of this concept. The articles also deliberated on 12 resistance strategies that women use to deal with DV; predominant among them are daily resistance, activities hidden for immediate and de facto gains (e.g., to avoid beatings, divorce and family disintegration, the decision to keep their children, and maintaining economic stability). The most common strategies are silence and not seeking help, reporting to family members or friends, seeking legal and social advice, and reporting to the police or healthcare provider.

ABSTRACT

Under climate change, extreme droughts will limit water availability for plants. However, the species-specific responses make it difficult to draw general conclusions. We hypothesized that changes in species' abundance in response to extreme drought can be best explained by a set of water economic traits under ambient conditions in combination with the ability to adjust these traits towards higher drought resistance. We conducted a 4-year field experiment in temperate grasslands using rainout shelters with 30% and 50% rainfall reduction. We quantified the response as the change in species abundance between ambient conditions and the rainfall reduction. Abundance response to extreme drought was best explained by a combination of traits in ambient conditions and their functional adjustment, most likely reflecting plasticity. Smaller leaved species decreased less in abundance under drought. With increasing drought intensity, we observed a shift from drought tolerance, i.e., an increase in leaf dry matter content, to avoidance, i.e., a less negative turgor loss point (TLP) in ambient conditions and a constancy in TLP under drought. We stress the importance of using a multidimensional approach of variation in multiple traits and the importance of considering a range of drought intensities to improve predictions of species' response to climate change.

ABSTRACT

Phenotypic plasticity is one of the main mechanisms of adaptation to abiotic stresses via changes in critical developmental stages. Altering flowering phenology is a key evolutionary strategy of plant adaptation to abiotic stresses, to achieve the maximum possible reproduction. The current study is the first to apply the linear regression residuals as drought plasticity scores while considering the variation in flowering phenology and traits under non-stress conditions. We characterized the genomic architecture of 17 complex traits and their drought plasticity scores for quantitative trait loci (QTL) mapping, using a mapping population derived from a cross between durum wheat (Triticum turgidum ssp. durum) and wild emmer wheat (T. turgidum ssp. dicoccoides). We identified 79 QTLs affected observed traits and their plasticity scores, of which 33 reflected plasticity in response to water stress and exhibited epistatic interactions and/or pleiotropy between the observed and plasticity traits. Vrn-B3 (TaTF1) residing within an interval of a major drought-escape QTL was proposed as a candidate gene. The favorable alleles for most of the plasticity QTLs were contributed by wild emmer wheat, demonstrating its high potential for wheat improvement. Our study presents a new approach for the quantification of plant adaptation to various stresses and provides new insights into the genetic basis of wheat complex traits under water-deficit stress.

ABSTRACT

We use a perceptual control model of identity to examine the relationship between stigmatized appraisals (from self and other) and well-being among individuals with serious mental illness. We also examine the role of stigma resistance strategies in the identity process. Using in-depth interviews with active clients of a community mental health center (N = 156), we find that deflection, or distancing oneself from mental illness, is associated with greater self-esteem and fewer depressive symptoms. Challenging others through education is associated with higher self-esteem, and challenging stigma through activism is associated with fewer depressive symptoms. Activism also moderates the relationship between identity discrepancy (the difference between appraisals from self and other) and well-being; however, the extent to which activism is helpful or harmful depends on whether appraisals from others are more or less stigmatizing than self-views. We discuss the implications of these findings for identity and stigma research.

ABSTRACT

According to the theory of planned behavior (TPB), intentions to perform a specific behavior are the result of attitudes, norms, and perceived control, and in turn, intentions and perceived control are the main predictors of the behavior. This study aimed to test the applicability of TPB in predicting alcohol use in normative pre-adolescents. The sample was composed of 755 Spanish adolescents aged 11 to 15 (M = 12.24; SD = 0.56), 47.1% females, from 12 state secondary schools in Spain. The results of path analysis indicate that positive attitudes towards alcohol, favorable norms towards alcohol, and offer vulnerability (perceived control) are significantly positively related to intentions to use alcohol as well as negatively related to actual behavioral control (i.e., actual strategies to avoid alcohol use). In turn, intentions to use and actual control predict higher alcohol frequency and heavy drinking. Significant indirect effects of these antecedents were found on alcohol outcomes through the mediation of intentions and actual control. The findings suggest that the validity and applicability of the TPB in normative pre-adolescents depend on the severity of alcohol use and point to a need to consider negative social influence in decision making processes in early adolescence.

ABSTRACT

Heavy metal pollution is a direct consequence of the extensive utilization of heavy metals in various industrial processes. The persistence and nondegradability of heavy metals cause them to bioaccumulate in nature, and when they come in direct contact with the pristine environment, they not only contaminate it severely but also pose dire consequences to the health of all living forms on earth, including humans. Chromium (Cr) is one of the heavy metals which has been extensively used in various industrial processes such as mining, alloy manufacturing, tanning of hides and skins, pigment production, etc. However, it is regarded as a priority pollutant due to its highly toxic, teratogenic, mutagenic, and carcinogenic nature, and the U.S. Environmental Protection Agency (EPA) also categorized it into group "A" human carcinogen. In contrast to water-soluble hexavalent chromium (Cr6+), its reduced form, trivalent chromium (Cr3+), is relatively benign and readily precipitated at environmental pH. Thus, bioremediation of Cr6+ through microorganisms including bacteria, yeast, and algae provides a promising approach to decontaminate a metal-polluted environment. This review describes an overview of the microbial reduction of Cr6+, resistance mechanism, and the antioxidant profiling exhibited by these microorganisms when exposed to Cr6+. It also describes the pilot-scale study of the successive use of bacterial, fungal, and algal strains and the subsequent use of microbially purified water for the cultivation of plant growth. Multiple metal-resistant microorganisms are a good bioresource for green chemistry to eradicate environmental Cr6+. KEY POINTS: • Hexavalent chromium (Cr6+) is highly toxic for living organisms including humans. • Microbial Cr resistance is mediated at the genetic, proteomic, and molecular levels. • Successive use of microorganisms is the best strategy to exterminate Cr6+from the environment.

ABSTRACT

BACKGROUND: Resistance to fungicides is one of the aspects that must be considered when planning treatments to achieve an optimal control of grey mold, caused by Botrytis cinerea, in vineyards. In this study, extensive fungicide resistance monitoring was carried out in Northern Italy (Lombardy region) to evaluate several aspects of fungicide resistance (frequency of resistance, effect of field treatments, mechanism of resistance and fitness) on 720 B. cinerea strains isolated from 36 vineyards. RESULTS: Of the characterized strains, 12% were resistant to a single fungicide class (3% to the succinate dehydrogenase inhibitor boscalid, 4% to the anilinopirimidine cyprodinil; 5% to the phenylpirrole fludioxonil; 0.1% to the ketoreductase inhibitor fenhexamid) and 0.8% to two fungicide classes contemporaneously. Resistance was associated with mutations reported in the literature for boscalid (H272Y/R) and fenhexamid (P238S or I232M). Two new mutations in sdhC (A187F) and in sdhD (I189L) could be related to boscalid resistance. Strains resistant to fludioxonil did not show any known mutations. No significant differences were found in the fitness of sensitive and resistant strains. CONCLUSION: Overall, field populations of B. cinerea showed a relatively low frequency of resistance, but the geographical distribution of resistance, genetic mechanisms of resistance and fitness of resistant strains suggest that management of resistance should be implemented, at local and regional levels. Particular attention should be given to the fungicide sprays planned before veraison, since they seem to be associated with a higher frequency of resistant strains in vineyards. © 2020 Society of Chemical Industry.

ABSTRACT

OBJECTIVE: We evaluated the perceived effectiveness of resistance strategies students could employ if approached to give away, trade, or sell their prescription stimulant medication, a growing concern on college campuses. Participants: We sampled undergraduates (N = 1,521) at three demographically dissimilar institutions between Fall 2017 and Spring 2018. Methods: We administered an anonymous, online survey and used linear mixed models to examine the effects of strategy type, face support (ie, adding politeness), and substance use history on perceived strategy effectiveness. Results: Internal (eg, "I am not comfortable sharing my medication") and external (eg, "My doctor won't prescribe me if I share") explanations were perceived to be most effective. Excuses, direct refusals, and suggesting an alternative (eg, energy drink) were less preferred. Adding face support improved perceived effectiveness for direct refusals and internal explanations. Conclusion: Preventive interventions for stimulant diversion could encourage the use of internal or external explanations or direct refusals with face support.

ABSTRACT

In anticipation of a drier climate and to project future changes in forest dynamics, it is imperative to understand species-specific differences in drought resistance. The objectives of this study were to form a comprehensive understanding of the drought resistance strategies adopted by Eastern Mediterranean woodland species, and to elaborate specific ecophysiological traits that can explain the observed variation in survival among these species. We examined leaf water potential (𝛹), gas exchange and stem hydraulics during 2-3 years in mature individuals of the key woody species Phillyrea latifolia L., Pistacia lentiscus L. and Quercus calliprinos Webb that co-exist in a dry woodland experiencing ~ 6 rainless summer months. As compared with the other two similarly functioning species, Phillyrea displayed considerably lower 𝛹 (minimum 𝛹 of -8.7 MPa in Phillyrea vs -4.2 MPa in Pistacia and Quercus), lower 𝛹 at stomatal closure and lower leaf turgor loss point (𝛹TLP ), but reduced hydraulic vulnerability and wider safety margins. Notably, Phillyrea allowed 𝛹 to drop below 𝛹TLP under severe drought, whereas the other two species maintained positive turgor. These results indicate that Phillyrea adopted a more anisohydric drought resistance strategy, while Pistacia and Quercus exhibited a more isohydric strategy and probably relied on deeper water reserves. Unlike the two relatively isohydric species, Phillyrea reached complete stomatal closure at the end of the dry summer. Despite assessing a large number of physiological traits, none of them could be directly related to tree mortality. Higher mortality was observed for Quercus than for the other two species, which may result from higher water consumption due to its 2.5-10 times larger crown volume. The observed patterns suggest that similar levels of drought resistance in terms of survival can be achieved via different drought resistance strategies. Conversely, similar resistance strategies in terms of isohydricity can lead to different levels of vulnerability to extreme drought.

ABSTRACT

Research on Jamaican socialization of children has primarily focused on parental discipline practices. Little is known about children's responses to parental attempts to control their behavior. The present study investigated mothers' perceptions of children's strategies for resisting their rules and requests. Thirty mothers living in Kingston and St. Andrew, Jamaica, participated in a 1- to 1.5-h semi-structured, open-ended interview regarding their 8- to 12-year-old children. Mothers reported that their children's resistance strategies included assertive refusal, arguing, ignoring/avoiding, attitude, and negotiation. Most mothers disapproved of their children's actions and responded with power-assertive strategies such as physical punishment, psychological control, forced compliance, and threats. Few mothers responded with autonomy support strategies including accommodation and reasoning. The findings provided insight into the ways Jamaican children use their agency to protect their autonomy despite their mothers' greater power, and the relational nature of children's influence on their mothers' behaviors and reactions. More research is needed to expand our knowledge of child agency in Afro-Caribbean families and the various ways that parents may support their growing autonomy that is socially constructive.

ABSTRACT

Sexual conflict is acknowledged as pervasive, with the potential to generate and maintain genetic variation. Mechanistic studies of conflict have been important in providing direct evidence for the existence of sexual conflict. They have also led to the growing realization that there is a striking phenotypic diversity of adaptations whose evolution can be shaped by sexually antagonistic selection. The mechanisms involved range from the use of genital spines, claspers, songs, and smells to ejaculate molecules. In one well-studied example, sexual conflict can occur over the sexually antagonistic effects of seminal fluid proteins in Drosophila melanogaster. However, an important puzzle remains, namely, why seminal fluid proteins are so numerous and complex, hence whether all or some are involved in mediating sexual conflict. I hypothesize that this rich diversity and the complexity of traits subject to sexually antagonistic selection in general may arise, at least in part, due to the deployment of sexually antagonistic adaptations in males in a way that lessens the probability of broadscale, strong resistance evolution in females. In elaborating this hypothesis, I explore how research into the evolution of resistance to insecticides, antimicrobials, and vaccines might be used to provide insights into the evolution of female resistance to the effects of sexually antagonistic manipulative traits of males. In this manner, the manipulative traits of males can be resistance-proofed.

ABSTRACT

The current study explored the impact of voicing non-consent in relation to rape. Aims of the study included determining (a) the prevalence of voicing non-consent, (b) the relationship of voicing non-consent to verbal and physical resistance, and (c) whether voicing non-consent predicts distress and rape acknowledgment. Out of 262 college women who experienced rape, 81% voiced non-consent. Voicing non-consent was related to verbal and physical resistance, but was distinct in prevalence and prediction of distress. Voicing non-consent was associated with trauma-related symptoms in multivariate models. Women who voiced non-consent were more likely to acknowledge their experience as rape or sexual assault. Implications are discussed.

ABSTRACT

Papaya leaf curl disease (PaLCuD) caused by papaya leaf curl virus (PaLCuV) not only affects yield but also plant growth and fruit size and quality of papaya and is one of the most damaging and economically important disease. Management of PaLCuV is a challenging task due to diversity of viral strains, the alternate hosts, and the genomic complexities of the viruses. Several management strategies currently used by plant virologists to broadly control or eliminate the viruses have been discussed. In the absence of such strategies in the case of PaLCuV at present, the few available options to control the disease include methods like removal of affected plants from the field, insecticide treatments against the insect vector (Bemisia tabaci), and gene-specific control through transgenic constructs. This review presents the current understanding of papaya leaf curl disease, genomic components including satellite DNA associated with the virus, wide host and vector range, and management of the disease and suggests possible generic resistance strategies.

ABSTRACT

Briskly evolving phytopathogens are dire threats to our food supplies and threaten global food security. From the recent advances made toward high-throughput sequencing technologies, understanding of pathogenesis and effector biology, and plant innate immunity, translation of these means into new control tools is being introduced to develop durable disease resistance. Effectoromics as a powerful genetic tool for uncovering effector-target genes, both susceptibility genes and executor resistance genes in effector-assisted breeding, open up new avenues to improve resistance. TALENs (Transcription Activator-Like Effector Nucleases), engineered nucleases and CRISPR (Clustered Regulatory Interspaced Short Palindromic Repeats)/Cas9 systems are breakthrough and powerful techniques for genome editing, providing efficient mechanisms for targeted crop protection strategies in disease resistance programs. In this review, major advances in plant disease management to confer durable disease resistance and novel strategies for boosting plant innate immunity are highlighted.

ABSTRACT

Neste artigo discutimos estratégias de resistência de moradores de uma comunidade situada na propriedade de uma usina sucroalcooleira. Nesta pesquisa realizamos entrevistas não-estruturadas com moradores, roda de conversa com trabalhadores da usina, visitas à comunidade e registros em diários de campo. Utilizamos o referencial teórico de Michel Foucault para discutirmos modos de resistência e relações de poder no contexto em estudo. As principais estratégias de resistência visibilizadas relacionam-se a projetar um futuro fora da usina para as novas gerações, enfrentamentos coletivos e individuais nas situações de trabalho e constituição de redes sociais de apoio. Apesar de marcados pelas assimetrias de poder produzidas no contexto da monocultura da cana-de-açúcar, os sujeitos não se constituem como passivos diante dos modos de vida instituídos. Eles denunciam, além da violência vivida na usina, a precariedade das políticas sociais de um Estado ausente para quem vive fora dos domínios da 'segurança' oferecida nas propriedades das usinas...


In this paper we discuss strategies of resistance from residents of a community located on the property of a sugarcane industry. In this research we conducted unstructured interviews with residents, group conversation with plant workers, community visits and records in field diaries. We use the theoretical framework of Michel Foucault to discuss strategies of resistance and power relations in the context under study. The main strategies of resistance visualized relate to design a future outside the plant for future generations, collective and individual confrontations in work situations, and the constitution of social support networks. Despite these subjects are marked by asymmetries of power produced in the context of the monoculture of sugar cane, they are not passive in face of the established ways of life. Besides the violence experienced at the plant, they denounce the precariousness of social policies on an absent state for those who live outside the realm of 'safety' offered in the properties of sugarcane industry...
