The solidarity economy beyond the issue of labor
Authors: Laville Jean-Louis , Silva Junior Jeová Torres
Published: August 2024

Abstract In this essay, we discuss the limitations of the orthodox approach of labor regarding solidarity economy, adopted by the International Labour Organization (ILO), and by the classical view of the sociology of work. Initially, we show that solidarity economy has been analyzed by the traditional sociology of work, both in Brazil and France, as an illusion of which participants are victims. ILO, although adopting lately a contrasting perspective, is restricted to a conception of decent work in solidarity economy that also keeps a common reference framework with the conservative perspective of the sociology of work. In the second part, we present two practices that show that solidarity economy cannot be reduced to the economic dimension of the production mode and labor relations, and that there is an inherent emancipatory political dimension - the cases of Conjunto Palmeiras (Brazil) and the Régies de quartier movement (France). From these cases, in the third section we identify the theoretical frameworks that not only understand the modes of work implementation in solidarity economy, but allow a wider integration of solidarity economy multiple dimensions. Therefore, we present three theoretical approaches: the Epistemologies of the South, the approach of substantive economic action, and the deliberative democracy perspective. At the end, we open up the reflection on the direction in which the sociology of work and the ILO can develop and reconfigure their reference approaches to work in an expanded, substantive and heterodox understanding of the solidarity economy.

Abstract The accurate determination of individual dry matter intake (DMI) is an important parameter for evaluating the nutritional value of a diet and allows for an adequate supply of food according to the nutritional requirements of each animal. When it is not possible to measure this parameter using a direct method, the DMI can be estimated based on faecal production markers and the in vitro digestibility of dry matter (IVDMD) of the diet. The objective of this study was to evaluate the effects of the external marker titanium dioxide (TiO2) and enriched and modified hydroxyphenylpropane (LIPE®) on DMI. Four multiparous Holstein × Gyr cows with an average of 60 days in milk and 488 kg of body weight were used. The animals were housed in a free stall barn and fed diets based on sugarcane silage supplemented with concentrate composed of ground corn, cottonseed meal and 0%, 5%, 10% and 15% whole cottonseed on a dry matter (DM) basis. A 4 x 4 Latin square design was adopted. The DMI was determined by the ratio between the faecal production estimated by the markers and the IVDMD of the diet, with faeces collected by rectal grabbing twice a day for a period of seven days. There was no difference (P>0.05) in the DMI estimated by the external markers TiO2 and LIPE® (10.3 vs. 12.1; 11.1 vs. 12.5; 10.2 vs. 12.9; and 12.7 vs. 10.9 kg/cow/day in relation to the measured DMI for diets with 0%, 5%, 10% and 15% inclusion of whole cottonseed, respectively). The external markers LIPE® and TiO2 proved to be suitable for estimating cow DMI. Regardless of the diet offered, both external markers can be used to replace the external marker chromic oxide, as the DMI estimated by them did not differ from the DMI measured in the trough.

Resumo A determinação acurada do consumo individual é um parâmetro importante para avaliação do valor nutritivo da dieta e permite o fornecimento adequado de alimentos, conforme as exigências nutricionais de cada animal. Quando há impossibilidade da sua mensuração pelo método direto, o consumo pode ser calculado a partir da produção fecal estimada por indicadores e pela digestibilidade in vitro da matéria seca (DIVMS) da dieta. Foi objetivo deste estudo avaliar os indicadores externos dióxido de titânio (TiO2) e hidroxifenilpropano enriquecido e modificado (LIPE®) nas estimativas de consumo de matéria seca (MS). Foram utilizadas quatro vacas multíparas Holandês × Gir com média de 60 dias em lactação e 488 kg de peso corporal. Os animais foram alojados em estábulo tipo free stall e alimentados com dietas à base de silagem de cana-de-açúcar suplementada com concentrado composto de milho moído, farelo de algodão e 0%, 5%, 10% e 15% de caroço de algodão (base da MS). Adotou-se delineamento quadrado latino 4 x 4. O consumo foi determinado pela razão entre a produção fecal estimada pelos indicadores e pela DIVMS da dieta, sendo as fezes coletadas diretamente na ampola retal, duas vezes por dia, por um período de sete dias. Não houve diferença (P>0,05) nos consumos de MS estimados pelos indicadores TiO2 e LIPE® (10,3 vs. 12,1; 11,1 vs. 12,5; 10,2 vs. 12,9; e 12,7 vs. 10,9 kg/vaca/dia em relação ao consumo mensurado, para as dietas com 0%, 5%, 10% e 15% de inclusão do caroço de algodão, respectivamente). Os indicadores externos LIPE® e TiO2 mostraram-se adequados para estimar o consumo de MS das vacas. Independente da dieta oferecida, ambos mostraram que podem ser utilizados em substituição ao indicador externo óxido crômico, pois, as estimativas de consumo estimadas por eles não diferiram do consumo mensurado no cocho.

Published: August 2024

Abstract Self-efficacy is defined as people’s beliefs in their own abilities to achieve something. This study aimed to systematically review the literature on psychological variables associated with self-efficacy in sport. Searches were conducted in six electronic databases: LILACS, PubMed, SciELO, SPORTDiscus, Web of Science, and Scopus, following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Content analysis of 29 included articles allowed for the identification of three research groups: psychological variables (n = 31; 72.1%), performance variables (n = 7; 13.3%), and other variables (n = 5; 11, 6%). There was a predominance of cross-sectional quantitative studies (72.4%; n = 21). The most used instrument was the General Self-Efficacy Scale (GSE), with 13 (44.8%) articles. In seven (24.1%) articles, specific questions were developed for the study. It is concluded that self-efficacy is a widely studied variable, but there is a lack of specific instruments in the Brazilian context of high-performance sports.

Published: August 2024

Abstract This study aimed to verify the prevalence of Attention Deficit Hyperactivity Disorder (ADHD) and Burnout Syndrome and the potential correlations between the dimensions of both conditions among Brazilian college students. A total of 751 students participated; 71.9% were women, aged 23 on average (SD = 3.46). The instruments included a sociodemographic questionnaire, the Adult Self-Report Scale (ASRS-18), and the Maslach Burnout Scale for Students (MBI-SS). Regarding the sex variable, men scored lower for emotional exhaustion and higher for professional achievement. The inattention facet of ADHD was positively correlated with the emotional exhaustion and depersonalization dimension and negatively correlated with professional achievement, suggesting a connection between the disorder and the syndrome. This study is expected to contribute to the development of preventive programs and intervention protocols especially designed to promote the mental health of students attending public and private educational institutions and experiencing academic burnout.
PAPEL DAS EMOÇÕES NA REDUÇÃO DO DESPERDÍCIO DE ALIMENTOS
Authors: Floriano Mikaela Daiane Prestes
Published: August 2024

RESUMO Este estudo teve como objetivo analisar o papel das emoções no comportamento de redução do desperdício de alimentos dos consumidores brasileiros. A partir de uma pesquisa com 235 respondentes e empregando-se a PLS-SEM como técnica de análise, verificou-se que os consumidores que se sentem mais culpados em relação ao desperdício apresentam atitudes mais favoráveis às ações de mitigação do descarte de alimentos em ambientes domésticos. Igualmente, o orgulho antecipado impactou diretamente a atitude em relação à redução do desperdício alimentar. Essas emoções também apresentaram efeitos indiretos sobre a intenção e o comportamento de redução do desperdício. Neste estudo, a distância psicológica moderou a relação entre intenção-comportamento, demonstrando que é mais provável que os consumidores se envolvam em práticas sustentáveis quando percebem o desperdício como uma problemática próxima a eles mesmos. Esta pesquisa oferece insights sobre estratégias que podem ser utilizadas para mitigar os comportamentos de desperdício.

Data-driven forecasting of embankment settlements on soft soils using constant rate of strain test data
Authors: Wan Xiao , Doherty James
Published: August 2024

Geotechnical engineers continually seek accurate methodologies for predicting the time-dependent settlement of embankments on soft soils. This paper introduces a novel data-driven approach that utilises constant rate of strain (CRS) test data to forecast embankment settlements. The proposed framework circumvents the requirement to subjectively assign soil parameters used in traditional forecasting models by directly integrating CRS test data into an automated analytical process, thereby significantly reducing manual effort and user-dependent variation in forecast results. The accuracy of the method is demonstrated through applications to real-world trial embankments in Australia and the Netherlands. All data used in this study are freely available in digital format from Datamap.

Published: August 2024

This study aimed to explored the relationship between basic Korean literacy skills and Korean language proficiency among international students who are learning Korean in a university language institute. Participants’ basic Korean literacy skills were measured by a set of tests including phonemic awareness and spelling. One hundred and eight international students who attended intermediate level Korean language classes participated in this study. The results showed that there was a significant correlation between their basic Korean literacy and Korean language proficiency. In particular, notable correlations with Korean language procificency were observed for basic vowels and the diphthongs ㅑ (ya) and ㅘ (wa), which are integral components of phonemic awareness and spelling tests conducted in a one-syllable (CV) structure. Furthermore, participants’ average accuracy in phonemic awareness test was only 59.92% and the average accuracy in spelling test was 72.48%. Considering that the test items were constructed with basic phonetic features of Korean language and orthography, their Korean literacy skills were found to be pretty limited, which were comparable to the native first-graders in Korea. Authors also compared the basic Korean literacy test scores between two groups who passes language course and who failed the course. The findings revealed that the basic literacy skills of the failed group was significantly lower than that of the passed group, indicating that phonemic awaeness and spelling abilities may affect Korean language proficiency and academic achievements. Authors discussed that Korean literacy of the foreign Korean language students are in needs of atttention among educators and researchers
The efficacy of Salvia-ligustrazine and Ligustrazine in treating gestational hypertension: A systematic review and meta-analysis

Published: August 2024

Pregnancy-induced hypertension syndrome (PIH), a prevalent and critical condition, has garnered increasing attention due to its significant impact on maternal and fetal health outcomes. The conventional treatment approaches rely on magnesium sulfate and various antihypertensive drugs; however, the clinical efficacy of these treatments is limited, highlighting the need to explore alternative avenues for improvement. Recently, a growing number of clinical studies have investigated the use of Salvia-ligustrazine or Ligustrazine in combination with conventional therapy. A comprehensive synthesis and critical analysis of these studies is necessary to evaluate the efficacy and safety of Salvia-ligustrazine or Ligustrazine in treating PIH. We sought all articles published prior to December 2, 2023, from seven databases to identify randomized controlled trials (RCTs) that involved traditional Chinese medicine Salvia-ligustrazine or Ligustrazine in combination with Western medicines for the conventional treatment of PIH, according to predefined inclusion criteria. The studies were assessed using the Cochrane Risk of Bias tool (ROB2.0), and meta-analyses were conducted using Stata 15.0 statistical software. We analyzed 47 RCTs encompassing 4,517 patients. The results demonstrated that combining Salvia-ligustrazine or Ligustrazine with Western medications was more efficacious than using Western medications alone. This combination improved the overall response rate, reduced the incidence of adverse pregnancy outcomes for mothers and infants, and decreased the occurrence of side effects associated with PIH treatment. While we evaluated the efficacy of traditional Chinese medicine injections of Salvia-ligustrazine or Ligustrazine alongside conventional Western treatments, our conclusions must be considered provisional due to potential bias and the limited availability of RCTs.

HSP90 is a target protein for ubiquitination in Giardia intestinalis
Authors: Chaparro Gutiérrez Jenny Jovana , Wasserman Moisés
Published: August 2024

Previous studies have demonstrated the existence and expression of genes essential to the process of protein ubiquitination in Giardia intestinalis, indicating that the ubiquitin-proteasome system may be involved in the degradation of proteins during its life cycle of the parasite. In this study, purification of ubiquitin was conducted from protein extracts of G. intestinalis trophozoites. Then, an anti-ubiquitin specific antibody was obtained to standardize an assay for the detection and evaluation of ubiquitination patterns. Finally, HSP90 was identified as an ubiquitinated protein in this protozoan. This post-translational modification could have regulatory effects associated with the functionality of the protein or its turnover to regulate key molecular events during the parasite’s life cycle.Key Words: protozoan, thermic shock protein, ubiquitin.ResumenEstudios previos han demostrado la existencia y expresión de genes esenciales para el proceso de ubiquitinación de proteínas en Giardia intestinalis, indicando que el sistema ubiquitina-proteosoma puede estar involucrado en el proceso de degradación de proteínas de este parásito durante su ciclo de vida.

Summary Anamnesis: a six-year-old milking Holstein cow (Bos taurus taurus) was diagnosed with stage IV Johne´s Disease (JD). Clinical and Laboratory findings: the cow suffered intermittent diarrhea during 6 months with no response to antibiotic treatment. Consequently, the cow was subjected to euthanasia. Treatment approach: antemortem milk and peripheral blood samples and postmortem colon, mediastinic, mesenteric lymph nodes, and spleen samples were processed for macrophages isolation. Total DNA was extracted from macrophages and used to diagnose IS900 of Mycobacterium avium paratuberculosis (MAP) through real time PCR. The MAP IS900 segment was successfully amplified from cells of all samples, indicating that these cells were MAP-infected macrophages. Conclusion: macrophages of cows suffering from JD can be used for amplification of the MAP IS900 segment. Key words: intracellular bacteria, real time PCR, resident macrophages, susceptible host.   Resumen Anamnesis: una vaca Holstein de 6 años de edad (Bos taurus taurus) presentó sintomatología de la fase IV de la enfermedad de Johne.

Measuring sustainability in aquaculture systems
Authors: Valenti Wagner C
Published: August 2024

SummarySustainability should be approached by four dimensions (scopes): economic, environmental, social and governance. All of them are important and should be equally considered. The huge difficulty to evaluate sustainability is the challenge to explore and analyze a system in a holistic way. It is essential to contemplate all dimensions of the production process and compare measurements of variables from very different nature. A few papers have been published using Ecological Footprint, Life Cycle Analysis and Energy Analysis to assess the sustainability of aquatic production systems. These methods give an integrated overview of the systems and are very useful. However, all of them request a huge amount of data, which is difficult to obtain. In addition, the two first focus mainly on environmental dimension.
Reforma al Sistema General de Regalías (SGR): ¿nuevas oportunidades en investigación o sofisma político?
Authors: Rodas Juan D
Published: August 2024

En 1994, y como producto indirecto de la constitución colombiana de 1991, se creó el Fondo Nacional de Regalías, el cual modificó la distribución a los entes territoriales de los recaudos por explotación de recursos naturales no renovables. Lo anterior representó un intento de descentralizar la administración de la economía, devolviendo a departamentos y municipios productores un mayor porcentaje de los réditos de minería y petróleo. A pesar de sus buenas intenciones, lo anterior generó un desbalance redistributivo, pues solo 8 de los departamentos colombianos -los generadores de la mayor parte de esta riqueza- recibirían recursos para reinversión en planes de desarrollo. Adicionalmente, esos entes territoriales no contaban con la suficiente transparencia institucional para manejar tan cuantiosos ingresos, lo que dio pie a una dudosa administración de los mismos. Mientras tanto, el resto de las regiones no productoras recibieron poco o nada de dichos recursos, largamente solicitados para atender sus necesidades.

Summary Background: breeding soundness evaluation (BSE) of males is crucial for reproductive success in sheep production systems. Objective: to determine the causes of failure when annual BSE was used to evaluate reproductive performance of rams. Methods: we analyzed 1,017 reproductive assessment records and assigned animals to young or mature groups. Animals were classified as approved or failed in the BSE. Statistical analyses were performed through Chi-square tests, correlation, and factor analyses. Results: our results clearly show the importance of regularly performing BSE to detect potential failures in rams that might reduce general fertility rates. Conclusions: consistent physical causes of failure were identified, and fertility rates varied according to age and year of examination. Key words: fertility, ovine, reproductive evaluation.   Resumen Antecedentes: la evaluación de la aptitud reproductiva (AR) del macho es crucial para el éxito reproductivo en los sistemas de producción ovina. Objetivo: determinar las causas de rechazo de carneros en el examen de la aptitud reproductiva. Métodos: fueron analizados 1.017 registros de evaluación reproductiva de carneros clasificados como jóvenes y maduros. Los animales fueron clasificados como aprobados o no en el AR. Los análisis estadísticos incluyeron prueba de chi-cuadrado, correlaciones y análisis de los factores. Resultados: nuestros resultados demuestran claramente la importancia de la realización periódica del AR, ya que hubo una reducción en las tasas generales de los rechazos después de haber sido implementado.

Authors: Cho Jin H , Kim In H
Published: August 2024

Background: dietary supplementation with organic acids and essential oils has positive effects on growth improvement and nutrient digestion. Microencapsulation of nutrients allow for the slow release of core materials in a specific period and/or environment. Objective: to investigate the effect of microencapsulated organic acids and essential oils (MOE) on growth performance, nutrient digestibility, blood and fecal characteristics in weanling pigs. Methods: one-hundred twenty-five weanling pigs [(Yorkshire × Landrace) x Duroc] with an average body weight (BW) of 6.76 ± 0.11 Kg were used in a 42-d experiment. Pigs were allotted to five dietary treatments according to initial body weight, using five replicates per treatment and five pigs per pen. Dietary treatments were: 1) NC (negative control): basal diet free of antibiotics; 2) PC (positive control), basal diet with tiamulin 39 mg/kg; 3) MOE0.5, basal diet with 0.5 g MOE/kg; 4) MOE1, basal diet with 1 g MOE/kg; and 5) MOE2, basal diet with 2 g MOE/kg. Results: final BW was greater in MOE2 and PC treatments compared to NC treatment (p < 0.05). Increased feed efficiency (G:F) was observed for MOE treatments during 0 to 7 d compared with NC and PC (p < 0.05). During 7 to 21 d, MOE0.5 and MOE1 supplementation decreased average daily feed intake (ADFI) compared with PC (p < 0.05). However, there were no differences in average daily gain (ADG) and G:F among treatments (p>0.05). During 22 to 42 d, ADG was greater for PC compared with NC (p < 0.05). The G:F of NC and MOE0.5 was lower than that of PC (p < 0.05). Overall, ADG and G:F were greater for PC compared to NC (p < 0.05). On 42 d, DM and N digestibilities in PC and MOE were greater (p < 0.05) than in NC. Fecal scores of pigs fed MOE1 were lower (p < 0.05) than those of pigs fed NC. Fecal pH was decreased in MOE0.5 and MOE1 when compared to NC (p < 0.05) on day 7. Fecal pH was decreased with MOE compared to NC and PC (p < 0.05) on d 21. Conclusion: MOE supplementation improved growth performance and nutrient digestibility while decreasing fecal scores and pH in weanling pigs.

Background: sugarcane silage often becomes a problem for the producers due to its high population of yeast and its high content of soluble carbohydrates. Objective: to evaluate the effect of formic and phosphoric acid on the chemical composition, fermentation characteristics, and digestibility of sugarcane silages. Methods: sugarcane was ensiled in experimental mini-silos. Five treatments were evaluated in the ensilage process (sugarcane added with 0.5 or 1% formic acid and 0.5 or 1% phosphoric acid, and a control treatment without additives). A completely randomized design was used. Results: the dry matter content of silages containing phosphoric acid was lower. Lower values of NDF, ADF, and hemicellulose were observed in the control and formic acid treatments. Conclusions: formic and phosphoric acids promote beneficial changes in the chemical composition of sugar cane silage.
The Maritime Smuggling Project: Challenges Within Collaborative Maritime Policing in The Netherlands
Authors: Boelens Mauro , Eski Yarin , De Rijk Danique
Published: August 2024

The Netherlands hosts a significant drug industry involving global crime groups targeting local professionals, such as fishers for drug smuggling, real estate agents for money laundering, and harbor masters for marina access. To raise awareness of potential criminal involvement, various government organizations collaborate within an Organized Crime Field Lab. This approach shifts the focus from repressively apprehending criminals to protecting legal businesses and professionals by enabling the public to inform, detect, and report smuggling activities, and by helping relevant sectors identify and regulate activities that facilitate organized crime. This article examines how maritime policing professionals experience the process, outcomes, and challenges within the Maritime Smuggling Project (MSP) and its contribution to building a more resilient society against criminal involvement. Based on 34 interviews, hybrid observations, and an online questionnaire with MSP participants, the study suggests that maritime criminal justice relies on the idea that a resilient community is less likely to engage in or facilitate criminal maritime activities. However, it also indicates that collaboration in itself is not enough to create an impact on policing. Findings reveal that innovations in criminal justice need open‐ended, long‐term, impact‐focused responses from projects like the MSP, along with maritime professionals willing to adopt new policing methods. Yet, traditional, path‐dependent criminal justice institutions often undermine these innovations by prioritizing immediate, measurable, short‐term results that benefit their organization instead of the overarching goal of preventing maritime crime and societal involvement in it. As a result, even those tasked with developing innovative approaches are limited by institutional constraints and ingrained habits.
