Arbete och liv - genuskontrakt i omförhandling?

Work is in this artide seen as a social phenomenon that has been defined in many different ways. However, the definitions have long been gender biased, in that men's traditional activities more often than women's have been defined as "work". Work has been defined as the opposite of leisure, of consumption, of non-production or of rest, hut work has also been defined for the purpose of assessing the level of economic activity in a society, for establishing the level of economic development and for comparing different societies in a number of ways. Many gender researchers have discussed the male bias in definitions of work, and the importance of developing definitions that include women's activities. Margaret Reid, followed by Karin Kock and others, developed the "third party criterion" for defining work. This criterion states that work includes waged work as well as work performed without payment but for which märket substitutes are available and acceptable. In the artide, the definition of Barbara Hilkert Andoisen is used in building a base for the long term purpose of developing an emancipatory work concept. The concept is bold, as such a work concept should include activities that are paid or unpaid, prescribed or voluntary, fulfilling or unpleasant, performed on a märket or within the family, in public services, in voluntary organisations, performed full-time, part-time or without working time being registered, and activities performed by people regardless of age, gender, class or ethnicity. Finally, the example of the Swedish pension reform in the 1990's shows that pressure for changing the present distribution of work is directed towards women, with no incentives for men to change traditional patters. The tacit agenda may be expressed as "do not disturb men" - women are allowed all kinds of work as long as their activities do not require men to change more than marginally.
Transitionsekonomierna och kvinnoarbetet. Könsperspektiv på den ryska arbetsmarknaden
Authors: Katz Katarina
Published: June 2022

Despite the dramatic changes in the economic system and in gender discourse in Russia over the last 10 years, gender differences in labour force participation and employment have remained more stable than expected. Women were at a disadvantage at work in the USSR and they remain so in today's Russia. Both men and women have left the labour märket, to a similar degree, but while the male exit is concentrated in young and old cohorts, women of reproductive age are less likely to be "at work". The gender wage differential appears to have increased by some percentage points. The limited quantitative evidence indicates that the main driving force behind this is the increase in income differentiation. Contrary to expectations, female unemployment is not larger than male.

Published: June 2022

In precision agriculture, the Normalized Difference Vegetative Index (NDVI) considers the spectral characteristics of healthy green vegetation. This index is an effective way of detecting the green state of plants. This is why we choose to use NDVI as a reference index to predict the effect of Root-Knot nematodes and grafting on vegetable crop health from proximal remote sensing machines. These machines were used to estimate different physiological, biochemical, and agronomic parameters as indicators of stress (GA, GGA, SPAD, and canopy temperature). Leaf level pigments were measured using a handheld sensor (SPAD). Canopy vigor and biomass were assessed using vegetation indices derived from RGB images and the NDVI was measured with a portable spectroradiometer (Greenseeker). The plant level water stress was assessed indirectly by plant temperature using an infrared thermometer. We conclude that the grafted plants were less stressed and more protected against nematode attack. The comparison of NDVI index predicted by AI models showed that artificial neural network MLP demonstrated the best prediction performance than the linear regression method. However, their R-squared decreased from 0.820 to 0.772, and NRMSE increased from 12.3% to 12.4%, respectively.
Étude de la diversité des Isopodes Terrestres dans les Agrosystèmes Oasiens de la Tunisie
Authors: Gabsi Fatma , Ehsine Mhammed , Medini-Bouaziz Lamia
Published: June 2022

Dans cette étude, plusieurs compagnes d’échantillonnage d’isopodes terrestres ont été réalisées dans différentes oasis du Sud Tunisien ainsi que dans d’autres sites hors oasis. Les résultats ont permis de recenser : dans les oasis, une douzaine d’espèces appartenant à trois familles Porcellionidae, Armadillidiidae et Armadillidae et dans les autres sites hors oasis, seulement 5 espèces faisant partie des 2 familles Porcellionidae et Agnaridae. Cette différence de la richesse spécifique pourrait être expliquée par les conditions climatiques différentes entre les deux sites étudiés. En effet, la majorité des espèces collectées dans les oasis sont caractéristiques des zones humides témoignant du rôle important des oasis dans le maintien de cette diversité spécifique des isopodes terrestres.
Atténuation de l'impact du déficit hydrique sur une culture de petit pois par la combinaison d'amendements organiques et de systèmes d'irrigation localisés

Published: June 2022

Cette recherche visait à évaluer l’impact de deux systèmes d'irrigation combinés à un amendement organique du sol, sur les paramètres hydrodynamiques et chimiques du sol et sur la productivité d'une culture de petit pois "Pisum sativum L. " soumise à des conditions de stress hydrique. Les résultats obtenus ont montré que les rampes poreuses permettent une meilleure stabilité du stock d'eau avec une amplitude de 30 mm contre 50,7 mm pour le système au goutte à goutte et un développement racinaire de petit pois plus intéressant avec une différence d'environ 2,5 cm par rapport au système de goutte à goutte. Le rendement n'a pas été significativement affecté et nous avons enregistré une différence de 3,43% en faveur des rampes poreuses. En revanche, la nodulation des racines et la fixation symbiotique de l'azote dépendaient du système d'irrigation, et nous avons trouvé une teneur en azote total plus élevée pour les sols irrigués par des rampes poreuses qui a atteint 1,4 g/kg. Les amendements organiques ont augmenté la teneur en humidité du sol à 24 et 25% pour la tourbe et le biochar respectivement par rapport au témoin. La croissance végétative de la plante a également été améliorée avec les amendements.

Published: June 2022

The aim of this study is to determine the phytochemical analyses, antioxidant and antimicrobial activities of Reamuria vermiculata leaves extracts. Organic extracts (methanol, hexane, ethyl acetate, petroleum ether) were screened for their biochemical composition as well as antioxidant and antibacterial activities. In fact, Phytochemical screening of Reamuria vermiculata leaves showed the presence of flavonoids, coumarins, saponins, tannins, terpenes, and quinones. Biochemical screening showed that the methanol was the richest extract in phenolic and tanins with 179.68 mg GAE/ g and 56.25 mg CE/g, respectively. The analysis of DPPH radical scavenging activity and ABTS showed an important scavenging with ethyl acetate extract with IC50 of 0.0012mg/mL, and 0.0006mg/mL respectively. As well as, the methanol extract exhibited an antimicrobial property against bacterial strains. Listeria monocytogenes and Salmonella typhimurium were the most sensitive strains with minimum inhibitory concentration values of 0.3125 mg/mL. These results allow us to propose that Reamuria vermiculata is an excellent source for bioactive molecules exhibiting interesting biological capacities.

THE DYNAMIC OF SERUM CYTOKINES IN PSORIASIS PATIENTS TREATED WITH SECUKINUMAB
Authors: Hao Nguyen Trong , Nguyen Pham Nhat
Published: June 2022

Introduction: Immunological mechanisms of psoriasis have been discussed widely in literature, including cytokines. There are relationships between serum IL-17A, IL-12, and TNF-α with psoriasis, and IL-17A is one of the target cytokines novel biologic therapies. The efficacy, safety, and mechanism of secukinumab were well known while the actual dynamic of circulatory cytokines is less well studied.  

Objectives: To study the dynamic of serum IL-17A, IL-12, and TNF-α in adult moderate-to-severe plaque psoriasis patients being treated with secukinumab in Ho Chi Minh City Hospital of Dermato-Venereology from July 2019 to May 2020.

Subjects and methods: We performed a case series on 35 patients in Ho Chi Minh City Hospital of Dermato-Venereology in the aforementioned period.

Results: Despite the patients’ well response to the secukinumab, the concentration of the three cytokines of interest at baseline did not relate to age, sex, age of onset, family history of psoriasis, BMI, metabolic syndrome, history of treatment, or achieving IGA 0/1 at week 12 (p ≥ 0.05). IL-17A and IL-12 correlation at the baseline was statistically significant (p=0.029, r = 0.37). Serum IL-17A and IL-12 were higher at week 12 compared to one at week 4. TNF-α increased at week 12 comparing to one at the baseline. All increases were statistically significant (p<0.05).

Conclusion: The paradoxical dynamics of the cytokines while treating psoriasis with secukinumab might potentially cause relapse and/or flare of psoriasis after stop using this agent. Although anti-IL-17A has high efficacy in the treatment of psoriasis, measuring the serum concentration of IL-17A at baseline may not have any essential role in predicting the response of psoriasis to secukinumab.

The Role of Informal Leader in Restraint and Confining People with Mental Health Issues in Manggarai, Indonesia
Authors: Eka Angelina Roida , Daulima Novy Helena Catharina , Susanti Herni
Published: June 2022

Introduction: A person experiencing mental health issues may be physically confined at the suggestion of an informal leader who sees that individual’s violent behavior as a threat to the community. Aims: The aim of the study is to explore the perceptions of the tu’a golo, a man who serves as informal village leader, regarding his role in confining a person with mental health issues in Manggarai, on the island of Flores, in Indonesia. Methods: The study uses an ethno-semantic approach. Data collection and analysis were carried out using Spradley’s Developmental Research Sequence; the researchers interviewed one tu’a golo from each of fifteen villages in Manggarai. They then analyzed the data via using domain, taxonomy, componential, and cultural themes. Results: The researchers found that the tu’a golo has three important roles in confining a person with mental health issues: (1) before physical restraint and confinement, as an adviser to the family and to the person exhibiting mental health issues; (2) before physical restraint and confinement, as a mediator between the family of the individual with mental health issues and the community; (3) during physical restraint and confinement, as a protector of the person with mental health issues, the family, and the community. Conclusions: In areas with limited mental health services, informal leaders take on important roles in the physical restraint and confinement of the mentally ill. Therefore, healthcare professionals must include informal leaders in programs to improve mental health services and reduce the use of physical restraint and confinement.

Authors: Hamvai Csaba , Hidegkuti István , Vargha András , Konkolÿ Thege Barna
Published: June 2022

Introduction: Parental burnout might take place when excessive demands overwhelm the parents’ resources. Aims: To develop and validate the Hungarian version of the Parental Burnout Assessment (PBA-HUN), an instrument designed to measure parental burnout; and to determine the prevalence of parental burnout in Hungary. Methods: Data were collected via an online survey from parents with at least one child living in the household (N = 1215; 82.6% mothers; Mage = 38.68 years; SDage = 6.27 years). Confirmatory factor analysis was used to investigate the factor structure of the PBA-HUN. Results: The four-factor structure of the original PBA was replicated, confirming the following factors: exhaustion in one’s parental role, contrast with one’s parental role, feelings of being fed up, and emotional distancing from one’s children. A second-order model with a higher-order factor representing overall parental burnout also fit the data well. The internal consistency of both the subscale and total scores was excellent (α ≥ 0.84). Parental burnout had a moderately strong negative correlation with life satisfaction, and weak or moderate positive correlations with perceived stress, depression, vital exhaustion, and COVID-specific perceived stress supporting the construct validity of the PBA-HUN. The prevalence of parental burnout stood at 5.8% in this sample. The weak relationship between PBA-HUN scores and sociodemographic factors was also similar to those found in prior studies. Parental burnout correlated negatively with the number of hours spent sleeping and engaging in spare time activity, respectively. Conclusions: The PBA-HUN is a reliable and valid tool to assess parental burnout in Hungary.

A composição de morcegos nos estados brasileiros vem sendo reportada. Porém, muitas regiões ainda permanecem desconhecidas e, nesse sentido, apresentamos a primeira lista de morcegos para o estado do Tocantins baseado em uma revisão de literatura, de modo a diminuir as lacunas de conhecimento sobre essa diversidade. Sistematicamente, a produção científica com quirópteros para o Tocantins é bastante recente, com aproximadamente 16 anos.  Um total de 86 espécies foi documentado, pertencentes as nove famílias ocorrentes no Brasil. Lacunas de conhecimento são detectadas, principalmente, nas regiões norte, noroeste e nas extensões oeste, sudoeste e nordeste. Esforços de amostragem utilizando acústica como novos métodos de amostragens são recomendados para elevar ainda mais a riqueza de animais. Sugerimos que, no futuro, cientistas da conservação, além de analisar a composição de espécies, análise da paisagem, possam também obter variáveis ecotoxicológicas para relacionar à segurança ambiental. A partir dessas análises poderão compreender a interação dos efeitos dos xenobióticos tanto na saúde desses mamíferos como na qualidade ambiental.
Avaliação da destinação de lodo biológico no cultivo de morango com aplicações de tebuconazol
Authors: Barwald Giani Mariza Britzius , Arsand Daniel Ricardo , Dutra Iago Riveiro Santos
Published: June 2022

O cultivo de morango é caracterizado pelo uso indiscriminado de agrotóxicos, o que pode causar não apenas contaminação alimentar, mas também o acúmulo de resíduos no ambiente e no homem. Técnicas que minimizem as concentrações residuais nos produtos e no ambiente são desejadas. Assim, este trabalho visou avaliar a utilização de lodo biológico de estações de tratamento de esgoto doméstico no cultivo de morango na degradação do fungicida tebuconazol (TEB) no solo, sua influência nas concentrações residuais e na atividade microbiana no solo. O experimento foi feito usando um planejamento experimental do tipo central composite design (CCD) com 10 tratamentos, sendo: fatoriais (combinações dos níveis +1 e -1), centrais (nível 0) e pontos axiais (+1,41 e -1,41). Foram realizadas análises físico-químicas e microbiológicas no solo e análises cromatográficas para detecção de resíduos de TEB no solo e no morango. Os resultados evidenciaram que maiores dosagens de TEB aplicadas ao cultivo de morango resultaram em maiores concentrações residuais desse fungicida no solo, porém não afetaram os teores residuais no fruto. A adição de lodo biológico ao solo durante o cultivo de morango resultou em maior atividade da biomassa microbiana, melhorando a estabilidade do solo. A destinação de lodo biológico ao solo durante o cultivo de morango mostrou-se adequada e resultou em melhoria na atividade microbiana do solo, o que pode proporcionar benefícios ambientais e econômicos.

Published: June 2022

A preocupação das populações de vários países e da comunidade científica global tem sido crescente nos últimos anos com relação às mudanças climáticas. O Aquecimento Global atinge níveis alarmantes e gera apreensão na comunidade internacional que teme danos irreversíveis ao planeta. A intensificação do Efeito Estufa em virtude da emissão excessiva de gases como o dióxido de carbono tem agravado esse cenário. Frente a esse problema, muitos pesquisadores têm dedicado seus esforços para criar tecnologias que visam neutralizar ou compensar os danos gerados pelos gases poluentes. Entre as alternativas disponíveis, o biossequestro de carbono ganhou espaço nos últimos anos, seu objetivo é utilizar organismos vivos para aprisionar o carbono atmosférico de forma a minimizar os impactos do aumento da temperatura do planeta. Esse artigo apresenta uma revisão da utilização de Escherichia coli, Microalgas e Árvores Geneticamente Modificadas, como biossequestradores potenciais de carbono atmosférico.

Published: June 2022

Diversos estudos evidenciam os usos da família botânica Arecaceae pelos humanos na Amazônia brasileira, assim, uma revisão abrangente que revele aspectos relacionados à produção científica acerca dos usos das palmeiras na região é o objetivo deste artigo. Em revisão sistemática, a partir das plataformas Web of Science, SciELO Citation Index e Catálogo de Teses e Dissertações – Capes, selecionou-se 37 estudos. Publicados entre 1992 e 2021, com concentração entre 2014 e 2017, os estudos foram conduzidos, sobretudo, nos estados do Amazonas e Pará, em áreas rurais, protegidas ou não. ‘Comunidades’ e ‘ribeirinhos’ foram os grupos sociais com maior quantidade de estudos realizados. Há tendência das pesquisas se concentrarem em categorias de uso das plantas, com destaque para usos medicinais, apesar de que a categoria ‘alimentação’ teve a maior quantidade de espécies citadas. Das 41 espécies identificadas nos estudos, Cocos nucifera, Euterpe precatoria e E. oleracea foram as mais frequentes e Astrocaryum aculeatum, C. nucifera e E. precatoria, as que obtiveram o maior número de categorias de uso identificadas. C. nucifera e E. precatoria se destacam como as palmeiras mais amplamente utilizadas, em termos geográficos e socioculturais. Há lacunas no conhecimento sobre interações entre humanos e palmeiras, como usos para fins ornamentais e tecnológicos, se sanadas, tem potencial para auxiliar na conservação da sociobiodiversidade na Amazônia brasileira.

Published: June 2022

O monitoramento e a adoção de ferramentas que auxiliem na tomada de decisões são fundamentais para a boa gestão da qualidade das águas de uma bacia hidrográfica. Diante disso, o presente trabalho utilizou o modelo matemático QUAL-UFMG com o objetivo de avaliar a capacidade de autodepuração do rio Araçuaí, em Minas Gerais, analisando as variáveis oxigênio dissolvido (OD) e demanda bioquímica de oxigênio (DBO) considerando os anos de 2016, 2017 e 2018 para calibração e o ano de 2019 para validação do modelo. Posteriormente foi simulado um cenário hipotético, considerando a implantação de estações de tratamento de esgoto com uma eficiência de 85% de remoção de DBO para todos os municípios da bacia que ainda não se encontram em operação, até o ano de 2033, tendo como base o Plano Nacional de Saneamento Básico - PLANSAB. Os resultados do modelo mostraram que tanto o processo de calibração quanto o de validação apresentaram bons resultados em relação ao índice RMEQ. Observou-se que a qualidade da água, após o lançamento de efluentes do município de Itamarandiba, não satisfaz as condições estabelecidas pela Resolução CONAMA 357/2005 no que diz respeito à variável DBO. Para a variável OD não foi constatada a desconformidade com a Resolução. A partir da simulação do cenário, observou-se que a implantação de ETE’s  para todos os municípios que ainda não possuem o tratamento de esgoto, faria com que a variável DBO atendesse os limites permitidos pela legislação para águas doce classe 2. Observou-se também que se a implantação da ETE fosse apenas no município de Itamarandiba, haveria melhora significativa na qualidade da água, fazendo com que 100% do rio Araçuaí entrasse em conformidade com a legislação. Logo, a análise possibilitou avaliar que as ações de melhoria do saneamento básico devem ser direcionadas para o município de Itamarandiba.

The Relationship between Reflective Disposition and Persistence in Education
Authors: Robinson Peter
Published: June 2022

Getting students to engage in reflective thought is a «wicked» problem in teaching. Students may demonstrate a resistance to any form of reflection, analysis or critical thought and instead automatically default to surface approaches which are non-productive in academic contexts. This resistance may involve an aversion which leads to students not persisting to higher levels of education and dropping out. The present study investigates the relationship between the resistance to reflective processing and persistence in education using the Cognitive Reflection Test (CRT) and some additional survey items aimed at testing surface processing tendencies in non-academic contexts. It provides support for the hypothesis that a general aversion to reflective processing appears to inhibit academic progression and correlates with drop-out from courses midstream. It closes by suggesting that aversion to analytical thinking may be a threshold issue that needs to be addressed separately before students can progress to any challenging content.
Selfee, self-supervised features extraction of animal behaviors

Published: June 2022

Fast and accurately characterizing animal behaviors is crucial for neuroscience research. Deep learning models are efficiently used in laboratories for behavior analysis. However, it has not been achieved to use an end-to-end unsupervised neural network to extract comprehensive and discriminative features directly from social behavior video frames for annotation and analysis purposes. Here, we report a self-supervised feature extraction (Selfee) convolutional neural network with multiple downstream applications to process video frames of animal behavior in an end-to-end way. Visualization and classification of the extracted features (Meta-representations) validate that Selfee processes animal behaviors in a way similar to human perception. We demonstrate that Meta-representations can be efficiently used to detect anomalous behaviors that are indiscernible to human observation and hint in-depth analysis. Furthermore, time-series analyses of Meta-representations reveal the temporal dynamics of animal behaviors. In conclusion, we present a self-supervised learning approach to extract comprehensive and discriminative features directly from raw video recordings of animal behaviors and demonstrate its potential usage for various downstream applications.
Kommunicera estetiska dimensioner
Authors: Jagell Elisabet
Published: June 2022

Både elever och lärare tycker att det är svårt att kommunicera kring estetiska dimensioner hos slöjdföremål och bristen på kommunikation kring detta kan påverka lärarnas möjligheter att inspirera, handleda och bedöma elever i slöjdprocessen. Studiens syfte är att undersöka hur estetiska dimensioner i slöjdföremål kan kommuniceras och hur det kan komma till nytta i slöjdundervisningen. Ett klipp från en filmad, digital visning av en slöjdutställning har analyserats ur ett intra-aktivt pedagogiskt perspektiv med hjälp av begrepp från bildsemiotik och socialsemiotiken. Genom att identifiera utställningsguidens verbala och icke-verbala resurser och hur dessa intra-agerar med varandra i samspel har fem områden som är till hjälp vid presentation av slöjdföremål identifierats: 1) Rummet, 2) Beröra och hantera, 3) Icke-verbala medspelare, 4) Urvalet och 5) Egna erfarenheter. De sätt som dessa områden påverkar kommunikation kring ett slöjdföremål kan överföras från utställningskontexten till slöjdundervisningen.

This article is the first report on the role of ultrasonic treatment (UST) on microstructural evolution, multiscale mechanical behavior, and tribological response in 2D tungsten disulfide (WS2) reinforced aluminum (Al6061) matrix composites. Delaunay triangulation calculations show that UST for 45 s enables a fourfold enhancement in the dispersion parameter of WS2 reinforcements in the Al6061 matrix from 0.08 to 0.32. Improved WS2 dispersion contributes to higher nucleation density with 52.7% grain refinement efficiency, achieving a fine‐grained Al6061–WS2 composite. The role of UST‐induced 2D reinforcement dispersion on the elastic deformation is established at progressively increasing length scales from individual grains to the bulk composite. It is accomplished by integrating the nanodynamic modulus mapping technique with a finite element modeling framework built on experimentally acquired microstructures and localized elastic moduli. It delineates a directly proportional relationship between UST‐induced dispersion and elastic modulus enhancement at all length scales from 10 to 700 μm. Excellent dispersion of the 2D layered WS2 homogenizes the tribological response of the composite material with a tenfold reduction in the volume of material lost during wear.
Hybrid Lithium‐Ion/Metal Electrodes Enable Long Cycle Stability and High Energy Density of Flexible Batteries

Published: June 2022

High‐energy, stable, and flexible lithium batteries are highly demanded for next‐generation flexible and wearable electronics. Although the cycling stability of flexible lithium‐ion batteries (LIBs) is high, their energy density reaches the bottleneck because of the use of graphite anode. On the other hand, flexible lithium‐metal batteries provide higher energy density because of the use of lithium (Li) metal anode, but the cycling stability is poor. Herein, a new type of flexible hybrid lithium‐ion/metal battery (f‐LIMB) is reported, which simultaneously possesses enhanced energy density, stable cycling behavior, and outstanding flexibility. f‐LIMB is enabled by using the prelithiated carbon cloth as the anode, which improves the initial Coulombic efficiency by a prior formation of solid electrolyte interface, benefits the subsequent deposition of Li metal due to the preformed lithiophilic LixC6 compounds, and enhances the cycle life and energy density of batteries through a Li compensation mechanism. The f‐LIMB full cell possesses an improved gravimetric and volumetric energy density by as much as 64% and 67%, in comparison to the flexible LIB counterpart, and pertains high capacity retention of 84% after 1000 charge/discharge cycles. In addition, the f‐LIMB can be readily bent down to a small radius of 2.5 mm.

The hypoxic nature of solid tumors limits the efficacy of radiotherapy (RT) and leads to radiation resistance. Hypoxic radiosensitizers can enhance tumor radiosensitivity by mimicking the effects of oxygen, but their efficacy has been limited by the heterogeneous oxygen distribution in tumor tissue. Herein, a multimodal therapeutic nanoplatform fabricated by co‐encapsulation of chlorin e6 and tirapazamine (TPZ) with an amphiphilic polymeric conjugate of cisplatin (CDDP) and metronidazole is reported. This platform could kill the tumor periphery cells by the deeply penetrated oxygen‐consuming sonodynamic therapy and unify the heterogeneously hypoxic context simultaneously, which then actuate the release and activation of the loaded TPZ. TPZ could further sensitize RT along with CDDP and metronidazole residues under the resultant hypoxic condition, which significantly decreases the radiation dosage required to cause massive cell damage. Except for the significantly suppressed tumor growth and metastasis caused by the multimodal therapeutic nanoplatform, its hypoxia‐directed feature also endows it with excellent safety.

Electrochemical structural reconstruction of catalysts may generate real active sites that differ from the initial catalyst, but is often ignored. Herein, combining in situ and ex situ techniques, it is identified that the bismuth nanosheets (NS) dotted with large numbers of coordinatively unsaturated pit sites is produced via the in situ structural reconstruction of Bi(OH)3 NS. Such reconstructed Bi NS shows greatly improved catalytic activity toward CO2 electroreduction, with a 2.6‐fold increase in current density compared with intact Bi NS, high Faradaic efficiency for HCOO− production (>95%), and an extraordinary turnover frequency of 0.35 s−1 at −0.98 VRHE. In addition, it delivers industrial‐relevant current density of 325 mA cm−2 without compromising selectivity in a flow cell. The mechanistic studies demonstrate that these coordinatively unsaturated sites acting as the real active sites favor the stabilization of key intermediate *OCHO, which thus facilitate the reaction kinetics for HCOO− production. This work not only provides a unique perspective on the construction of efficient catalysts for CO2 electroreduction, but also implies the importance in recognition of structural reconstruction.

A suitable statistical model for the analysis of repeated measures is a prerequisite for an accurate genetic selection of cacao (Theobroma cacao L.) genotypes. Thus, the objectives of this study were to (a) evaluate homoscedastic and heteroscedastic repeatability models, (b) estimate the optimal number of harvest years for genetic selection, and (c) identify and select biparental crosses with high productivity, witches' broom (Moniliophthora perniciosa Stahel & Philips‐Mora) resistance, stability, and adaptability. Twenty biparental crosses were evaluated in a complete randomized blocks design, with seven replications and 12 trees per plot for 10 harvest years. Evaluated traits were number of healthy fruits (NHF), number of symptomatic fruits for witches' broom (NWBF), dry bean weight (DBW), and fruit index (FI). Variance components were estimated by restricted maximum likelihood, and genotypic values were predicted by best linear unbiased prediction. The best‐fitted repeatability model for each trait was indicated by Akaike's information criterion. The additive index was used for simultaneous selection for productivity, witches' broom resistance, stability, and adaptability. The heteroscedastic repeatability model showed the best fit for all traits. For HF, WBF, and FI, two and seven harvest years were sufficient for selection aiming at recombination and recommendation, respectively. For NWBF, evaluated only from the seventh year onwards, one harvest year was enough for recombination and three for recommendation. Five biparental crosses with high productivity, witches' broom resistance, stability, and adaptability were selected for recombination and/or for competition trials for recommendation. Such results can help define efficient strategies and optimize cacao breeding programs.
Fostering and sustaining transnational solidarities for transformative social change: Advancing community psychology research and action

Published: June 2022

As we planned this special issue, the world was in the midst of a pandemic, one which brought into sharp focus many of the pre‐existing economic, social, and climate crises, as well as, trends of widening economic and social inequalities. The pandemic also brought to the forefront an epistemic crisis that continues to decentre certain knowledges while maintaining the hegemony of Eurocentric ways of knowing and being. Thus, we set out to explore the possibilities that come with widening our ecology of knowledge and approaches to inquiry, including the power of critical reflective praxis and consciousness, and the important practices of repowering marginalised and oppressed groups. In this paper, we highlight scholarship that reflects a breadth of theories, methods, and practices that forge alliances, in and outside the academy, in different solidarity relationships toward liberation and wellbeing. Our desire as co‐editors was not to endorse the plurality of solidarities expressed in the papers as an unyielding methodological or conceptual framework, but rather to hold them lightly within thematic spaces as invitations for readers to consider. Through editorial collaboration, we arrived at the following three thematic spaces: (1) ecologies of being and knowledge: Indigenous knowledge, networks, and plurilogues; (2) naming coloniality in context: Histories in the present and a wide lens; (3) relational knowledge practices: Creative joy of knowing beyond disciplines. From these thematic spaces we conclude that through repowering epistemic communities and narratives rooted in truth‐telling, a plurality of solidarities are fostered and sustained locally and transnationally. Underpinned by an ethic of care, solidarity relationships are simultaneously unsettling dominant forms of knowledge and embrace ways of knowing and being that advances dignity, community, and nonviolence.

Homelessness poses risks to the health and safety of young adults; particularly among sexual and gender minority (SGM) young adults. The current study sought to better understand service use and perceived safety in community and service settings among SGM and cisgender heterosexual (cis‐hetero) young adults experiencing homelessness. Data come from a mixed‐method, ecological momentary assessment study (n = 80; 43% sexual minority; 10% gender minority) in Los Angeles, California. Participants reported their current location (service vs. nonservice setting) and perceived safety. Multilevel modeling examined associations between identity, location, and perceived safety; qualitative interviews with 20 SGM participants added context to quantitative findings. Overall, service location was associated with greater perceived safety (β = .27,p < .001). Compared to cis‐hetero participants, cisgender sexual minorities (β = −.23,p = .03) and sexual and gender minorities (β = −.50,p = .002) reported lower perceived safety in service settings (vs. nonservice settings). Qualitative interviews revealed themes and subthemes detailing safe/unsafe spaces and interpersonal conflict in the community, and relationships with staff, peers, transphobia, and positive experiences in service settings.
