Farmers’ markets as a sustainable model of producers-consumers relationships: evidence from Tuscany
Authors: Mengoni Matteo , Marescotti Andrea , Belletti Giovanni
Published: August 2024

Evidence from the literature emphasize the role of Farmers’ Markets (FMs) in enhancing economic benefits for both producers and consumers, improving social outcomes and benefiting the environment. Therefore, FMs can be conceived not just as an alternative to the market, but also as a specific way of shaping producers-consumers relationships, which influences and is at the same time the result of their respective selling-buying models. This article aims at investigating the hypothesis of FMs as a specific and structural form of producers-consumers relationships, and collecting evidence on their perceptions, motivations and behaviour at the markets, and on the impact of selling and purchasing at these FMs on sustainability dimensions. For this purpose, we selected a sample of FMs in the north of Tuscany (Italy) and submitted two in-person semi-structured questionnaires, to both producers and consumers. The methodology was based on actors’ self-assessment supported by guiding interviewers. Results showed how producers and consumers participating in FMs, although with differences across FMs types, do not only activate market relationships, but share, learn and build values together. Indeed, FMs are perceived by the actors involved as a structural and alternative framework, giving space and shaping alternative producers-consumers connections.
Can the territorial food system provide solutions to recurring crises in the global food system?
Authors: Pecqueur Bernard
Published: August 2024

The issue of food has evolved significantly in recent years throughout Europe, under the pressure of environmental and climate constraints as well as a set of factors related to food dependence and changes in consumption patterns. Short circuit practices, embedded in localized agrifood systems, although in the minority in terms of volumes consumed, are growing rapidly and are a sign of these developments. The recent health crisis has further highlighted the need to think of food as a global system with many variables and multiple interdependencies between these. This article outlines the global food system that has resulted from the modernization of agriculture in Europe and North America, and the powerful movement of globalization on a global scale. It describes the emergence of a territorial food system with characteristics that are distinct from the overall system. Finally, the article explores the alternative nature of the territorial system and its ability to provide solutions to recurring crises in the global food system.

Published: August 2024

O texto aborda a trajetória da parda liberta Margarida Maria de Jesus, através das relações sociais desenvolvidas por ela a partir das lutas por liberdade jurídica, as estratégias empreendidas para sua conquista e manutenção desta. Utilizando-se de registros eclesiásticos, cartoriais e judiciais produzidos nas cidades de Lages-SC e Vacaria-RS nas décadas finais do século XIX e início do XX, localizamos suas redes de sociabilidade em uma sociedade marcada pela exclusão social de mulheres negras. O objetivo é demonstrar o protagonismo de Margarida na conquista de sua liberdade por meio de uma Ação de Liberdade de 1884 na cidade Lages/SC e acompanhar sua trajetória em liberdade. A pergunta que nos guiou é: quais rede de acolhimento e apoio auxiliaram em seu protagonismo? Sua trajetória e relações estão fundamentadas na perspectiva interseccional (gênero, raça e classe) proposta pela literatura do feminismo negro.

Big Data analytics can handle massive volumes of organized and unstructured data in real time, making risk management more flexible and proactive. Predictive analytics, machine learning, and data mining help firms see dangers before they become major difficulties. Big Data analytics in risk management provides full IT infrastructure insights. By examining network logs, user activity patterns, and system performance indicators, enterprises may spot abnormalities and security breaches early. This lets IT teams reduce hazards quickly, reducing service disruption. Big Data analytics also allows firms to monitor IT systems continuously and respond to evolving threat environments.
Challenges and Solutions in High-Speed SerDes Data Path Design
Authors: Aravindsundeep Musunuri  , Pandi Kirupa Gopalakrishna Pandian  , DR.Punit Goel
Published: August 2024

Modern high-performance communication systems require high-speed Serializer/Deserializer (SerDes) data path design to meet the growing demand for data throughput and reliability due to technological advancements and data-intensive applications. This research article examines the complex problems of designing high-speed SerDes data routes and suggests novel solutions.
Data fidelity across high-speed channels requires signal integrity, the first key difficulty. Attenuation, crosstalk, and EMI may degrade SerDes signal performance. Advanced methods like equalization, impedance matching, and effective shielding mitigate these impacts. Equalization, including feedforward and feedback methods, reduces channel losses and distortions, enhancing signal quality. Power consumption is another major issue as data rates and system complexity rise. Power-hungry high-speed SerDes circuits cause thermal management and energy efficiency difficulties. Adaptive power management, low-power design, and new materials with higher thermal performance and lower power dissipation are discussed in the study.
Design complexity is another issue in high-speed SerDes data route design. High-precision timing and synchronization and many component integration in a small area need advanced design tools and methods. The study emphasizes simulation and modeling for complexity management and design for testability (DFT) for full verification and debugging.

Published: August 2024

Culture as a state identity must always be preserved so that it remains alive and relevant for every generation of society. Indonesia has a variety of cultures, including traditional music on the island of Java, namely Karawitan Art. The process of cultural inheritance can be through educational institutions which are leading institutions that are in direct contact with the nation's generation. So this research was taken to describe the efforts made by educational institutions in contributing to preserving the traditional culture of karawitan art concretely.  A study designed using a qualitative approach with a case study type . Data was obtained through observation, interviews and documentation. The informants are educators and trainers. The number of students is 26 children, all of whom participated in karawitan activities. This karawitan group is named "Karawitan Cilik". The learning method of karawitan art uses the habituation method. Learning the art of karawitan is proven to support children's development, including in physical, motor, cognitive, social-emotional, moral, language and art aspects. The learning of karawitan art carried out by educational institutions is a form of contribution to preserving traditional culture in the surrounding environment. In addition, this activity can also be a meaningful learning for students.
Strategy for Compensation of Thermally Induced Displacements in Machine Structures Using Distributed Temperature Field Control
Authors: Pöhlmann Patrick , Müller Jens , Ihlenfeldt Steffen
Published: August 2024

Thermal deformation is a major source of machining errors in modern machine tools. In addition to optimising the machine structure, correcting the axis position values in the numerical control is a common measure to reduce these errors. Another possibility is to directly influence the temperature field of the machine tool in the process, which requires a complex thermo-elastic modelling approach as well as appropriate thermal actuation and measurement capabilities. This paper presents a strategy for controlling the temperature field based on the eigenmodes of the thermal system. The various aspects of the concept are explained using a finite element model of an exemplary structural component. The basis is the modal analysis of the thermal system, which allows the temperature field to be described by independent discrete states. In addition to the placement of thermal sensors and actuators, this work focuses on the design of a suitable control approach. Transient simulation results are used to clearly demonstrate the performance of this method.

Attending is not enough: Responding to targets is needed for across-trial statistical learning
Authors: Li Ai-Su , van Moorselaar Dirk , Theeuwes Jan
Published: August 2024

Recent evidence shows that observers are able to learn across-trial regularities as indicated by faster responses to targets whose location was predicted by the target’s location on the preceding trial. The present study investigated whether responding to both targets of the pair, as was the case in studies thus far, was needed for learning to occur. Participants searched for a shape singleton target and responded to the line inside. There were two across-trial predicting-predicted regularities regarding target locations: if the target appeared at one specific location on a given trial, it would appear at another specific location on the next trial. Unlike previous experiments, for one of these regularity pairs a response was only needed on either the first or the second target in the pair. Experiment 1 showed that across-trial learning only occurred when responding was required to both targets of a pair. If the response to one target of a pair had to be withheld, no learning occurred. Experiment 2 showed that the absence of learning cannot be attributed to carry-over inhibition resulting from not having to respond. After learning across-trial contingencies, learning remained in place even when the response to the first target of the pair had to be withheld. Our findings show that the execution of the (arbitrary) simple key-press response for both trials of the pair was needed for across-trial statistical learning to occur, whereas solely attending target locations did not result in any learning.

Authors: Fansyuri Nasution Hamzah , Suranti Dewi , Fredricka Jhoanne
Published: August 2024

The case data management process handled by Bengkulu District Prosecutor's Office uses computers using office applications to create letters and tables of evidence for each case. The large amount of case data that comes in every day means that staff need quite a long time to make reports. Apart from that, the staff searched for data on cases that had occurred previously where there was a request from the head of the prosecutor's office, but this took quite a long time because the data that had been processed was already in the form of data archiving so that the staff had to manually search for the case data one by one. This reduces the effectiveness and efficiency of the performance of each staff member at Bengkulu District Prosecutor's Office. The application of the Sequential Searching Method in searching for case data at Bengkulu District Prosecutor's Office is a forum built to make it easier for staff at the office to manage case data and search for case data that has been entered. Apart from that, it can help staff in archiving data on cases that have been handled every month. To make it easier for staff to manage case data, a web-based application was built that can be accessed via a browser created using the PHP programming language and MySQL database.

A EXTENSÃO RURAL E A BIOSSEGURIDADE
Authors: Sperotto Laura Galvão , Oelke Carlos Alexandre , Sperotto Leandro Tiago
Published: August 2024

Este texto tem a intenção de apresentar discussões sobre a importância da extensão rural em propriedades avícolas como promotora de eficiência em diversos fatores de produção, principalmente na biodiversidade. Observa-se que a assistência técnica aplicada nas micro propriedades, não é tão eficiente quanto a extensão rural, sendo um dos motivos o relacionamento humano com os pequenos agricultores, um dos grandes diferenciais do extensionista rural. Também se observou que o comércio exterior tem se baseado muito na biodiversidade, o que força as empresas frigoríficas do setor a se dedicarem cada vez mais em promover melhorias nos processos, sendo estes os obstáculos das empresas avícolas, pois precisam que os agricultores atuem de forma dinâmica nos processos produtivos, em busca de padronização e sanidade. Conclui-se que a extensão rural é, atualmente, a melhor forma de gestão da produção avícola em larga escala.

Neutron Star Kicks plus Rockets as a Mechanism for Forming Wide Low-eccentricity Neutron Star Binaries
Authors: Hirai 平井 Ryosuke 遼介 , Podsiadlowski Philipp , Heger Alexander , Nagakura 長倉 Hiroki 洋樹
Published: August 2024

Recent neutron star surface observations corroborate a long-standing theory that neutron stars may be accelerated over extended periods after their birth. We analyze how these prolonged rocket-like accelerations, combined with rapid birth kicks, impact binary orbits. We find that even a small contribution of rocket kicks combined with instantaneous natal kicks can allow binaries to reach period–eccentricity combinations unattainable in standard binary evolution models. We propose these kick + rocket combinations as a new channel to form wide low-eccentricity neutron star binaries such as Gaia NS1, as well as inducing stellar mergers months to years after a supernova to cause peculiar high-energy transients.

Authors: Won Hoyoun , Bae Jae Hyun , Lim Hyunjung , Kang Minji , Kim Minjoo , Lee Sang-Hak ,   on behalf of the Clinical Practice Guidelines Committee, Korean Society of Lipid and Atherosclerosis (KSoLA)
Published: August 2024

Elevated blood cholesterol and triglyceride levels induced by secondary causes are frequently observed. The identification and appropriate handling of these causes are essential for secondary dyslipidemia treatment. Major secondary causes of hypercholesterolemia and hypertriglyceridemia include an unhealthy diet, diseases and metabolic conditions affecting lipid levels, and therapeutic side effects. It is imperative to correct secondary causes prior to initiating conventional lipid-lowering therapy. Guideline-based lipid therapy can then be administered based on the subsequent lipid levels.
Enhancing in-plane uniformity of graphene nanowalls using a rotating platform for solid-state lithium-ion battery

Published: August 2024

In the realm of solid-state lithium-ion battery (SLIB) research, anode development remains a focal area because the interface between the solid electrolyte and the anode plays a critical role in determining battery performance. Among various anode materials, vertically aligned graphene nanowalls (GNWs) stand out as a promising candidate due to their extensive surface area, sharp exposed edges, and high conductivity. These features give GNWs great potential to enhance the efficiency and capacity of solid-state batteries. However, the plasma generated in microwave plasma chemical vapor deposition (MWPCVD) equipment chamber exhibits uneven distribution, making it challenging to achieve uniform growth of GNWs over a large area. To improve the in-plane uniformity during the growth of GNWs, a drive motor was installed beneath the substrate holder, allowing the substrate to rotate at a constant speed during the film deposition process, thus enhancing the in-plane uniformity of the GNWs. This paper also showed that the charge-discharge properties of SLIBs are improved with substrate rotation. Compared with the previously reported method of producing uniform microwave plasma through rapid rotation and slow pulsation in a resonant field, this modification of the apparatus is simpler. Additionally, the use of a mixed gas can effectively improve the uniformity of the in-plane GNW films, providing a viable reference for the mass production of SLIB anode electrodes.
An efficient augmented memoryless quasi-Newton method for solving large-scale unconstrained optimization problems
Authors: Cheng Yulin , Gao Jing
Published: August 2024

In this paper, an augmented memoryless BFGS quasi-Newton method was proposed for solving unconstrained optimization problems. Based on a new modified secant equation, an augmented memoryless BFGS update formula and an efficient optimization algorithm were established. To improve the stability of the numerical experiment, we obtained the scaling parameter by minimizing the upper bound of the condition number. The global convergence of the algorithm was proved, and numerical experiments showed that the algorithm was efficient.
Trust in Cryptocurrency Payments

Published: August 2024

Although cryptocurrencies are not yet widely used as a method of payment in retail and commercial transactions, they are attracting a growing level of interest. However, if cryptocurrencies are to attract mass adoption for settlement, they will need to have merchant and consumer trust. This paper examines the factors which contribute to the development of trust, and whether the perception of trust varies between cultures (Arab and non-Arab). To explore this, the study analysed, using multigroup partial least squares analysis, 729 survey responses. The analysis examined the impact of four factors on perceived trust in cryptocurrency payments, and found that the perception of information confidentiality, identifiability and traceability all have a significant effect, while perceptions of fraud vulnerability had very little impact. There were also clear socio-cultural effects. This research offers significant insights into the trust dynamics essential for the acceptance of crypto-payment-services and highlights the importance of culture perspectives.
Para uma compreensão da lenta e inevitável evolução da Educação de Infância: Análise do discurso sobre a Educação de Infância no Estado Novo português (1933-1974)
Authors: Vilhena Carla Isabel Franco da Cruz Cardoso , Ferreira António Gomes , Mota Luís Carlos Martins d’Almeida
Published: August 2024

Pretende-se, através deste artigo, contribuir para a compreensão do processo de desenvolvimento da Educação de Infância em Portugal no período do Estado Novo (1933-1974), um regime político conservador, nacionalista e autoritário. Neste sentido, procedeu-se à análise crítica do discurso sobre a Educação de Infância que circulou no período em estudo, com o objetivo de compreender os argumentos utilizados para justificar, ou não, a criação de instituições de educação de infância, bem como as ideias acerca da forma como se devia processar a educação das crianças mais pequenas, utilizando como fontes um conjunto de revistas de educação e ensino que circularam em Portugal nos 41 anos de duração do Estado Novo. A nossa análise permitiu observar que se assistiu, durante esse período, a importantes transformações no discurso acerca da Educação de Infância. Se num primeiro momento (1933-1944) prevaleceu um discurso médico-higienista em que se privilegiava a função assistencial, a partir de meados dos anos 40, assiste-se ao predomínio de um discurso psicopedagógico, assente na revalorização da função educativa e na defesa da generalização da Educação Pré-Escolar. No que diz respeito aos métodos pedagógicos, o método Montessori foi considerado, ao longo do intervalo de tempo analisado, como o mais adequado para a educação das crianças mais pequenas.
A proposta socioeducativa do Regime Militar presente na FUNABEM e no I Fórum de Menores
Authors: Santos Maria Escolástica de Moura , Melo Mayara Macêdo
Published: August 2024

Este estudo tem como objetivo compreender a relação trabalho e educação na proposta socioeducativa voltada para crianças e adolescentes pobres durante o Regime Militar, expressa nos documentos da Fundação Nacional do Bem-Estar do Menor (FUNABEM) e no discurso das autoridades presentes no I Fórum do Menor. Para tanto, buscamos identificar os fins e os meios educativos apontados no referido material; analisar a relação entre essa proposta educativa e a Ideologia da Segurança Nacional; e desvelar o vínculo ideológico entre as propostas de assistência e de educação para crianças e adolescentes pobres e a preparação de mão de obra barata para o mercado de trabalho. Trata-se de pesquisa com caráter teórico e documental ancorada nos pressupostos do Materialismo Histórico e Dialético, sobretudo nas obras de Marx (2011), Engels (2009) e Mészáros (2011, 2015), para compreendermos origem e função do Estado, com destaque aos postulados de Lukács (2007, 2013) sobre o trabalho ontológico. A revisão de literatura ancora-se em Bazílio (1985), Becher (2011), Silva (2011) e Celestino (2015), dentre outros, e a interpretação dos dados busca respaldo na técnica de análise de conteúdo de Bardin (2016). Como resultado destacamos que a criança pobre denominada menor é considerada perigosa ou imprestável, em geral, fruto de uma família desajustada, portanto, o indivíduo deve ser corrigido, não a sociedade. Nesse processo de modelagem, a educação assume centralidade, sendo responsável por garantir o ajustamento desses indivíduos à ordem social vigente, por meio da formação para os ofícios manuais, cuja finalidade é transformá-los em adultos úteis a si mesmos e à nação.

The increased incidence of invasive pulmonary aspergillosis, caused by Aspergillus fumigatus, occurring in patients infected with severe influenza or SARS-CoV-2, suggests that antiviral immune responses create an environment permissive to fungal infection. Our recent evidence suggests that absence of the type I IFN receptor 2 subunit (IFNAR2) of the heterodimeric IFNAR1/2 receptor is allowing for this permissive immune environment of the lung through regulation of damage responses. Because damage is associated with poor outcome to invasive pulmonary aspergillosis, this suggested that IFNAR2 may be involved in A. fumigatus susceptibility. In this study, we determined that absence of IFNAR2 resulted in increased inflammation, morbidity, and damage in the lungs in response to A. fumigatus challenge, whereas absence of IFNAR1 did not. Although the Ifnar2−/− mice had increased morbidity, we found that the Ifnar2−/− mice cleared more conidia compared with both wild-type and Ifnar1−/− mice. However, this early clearance did not prevent invasive disease from developing in the Ifnar2−/− mice as infection progressed. Importantly, by altering the inflamed environment of the Ifnar2−/− mice early during A. fumigatus infection, by neutralizing TNF-α, we were able to reduce the morbidity and fungal clearance in these mice back to wild-type levels. Together, our results establish a distinct role for IFNAR2 in regulating host damage responses to A. fumigatus and contributing to an A. fumigatus–permissive environment through regulation of inflammation. Specifically, our data reveal a role for IFNAR2 in regulating TNF-α–mediated damage and morbidity during A. fumigatus infection.

Self-reported practices of sepsis and Septic Shock (SS) among healthcare providers were rarely discussed in the literature. The aim of the study was to describe the level of adherence among nurses and physicians to the self-reported practices of sepsis and SS treatment in six Intensive Care Units (ICU) of two tertiary hospitals in Jordan. A cross-sectional descriptive design was used. A questionnaire was administered to 119 nurses and physicians. Descriptive statistics were used to describe sample characteristics and practices of sepsis treatment. The results showed that most nurses and physicians reported they “often” or “always” adhere to these practices. However, there was insufficient adherence to using a prone position in patients with sepsis-induced acute respiratory distress syndrome. Moreover, there was insufficient practice of testing serum lactate levels within one hour of diagnosing patients. Nurses’ and physicians’ self-reported adherence to sepsis and SS treatment is satisfactory, but further improvement is required.

Published: August 2024

Background:

Epidemiology of multiple sclerosis (MS) in Libya had been studied at different intervals, but not focused on newly diagnosed patients with MS (pwMS).

Objective:

The objective of this study was to study the demographic, clinical, and paraclinical characteristics of pwMS and to find out whether the Libyan population had similar features of MS compared to other Arab countries and the rest of the world.

Materials and Methods:

This was a retrospective study conducted at MS clinic in Benghazi Medical Centre, Libya, from November 1, 2016 to December 31, 2021. The patients who were fulfilling the 2017 McDonald’s diagnostic criteria and registered at the MS clinic were included in the study. Data were collected and statistically analyzed with appropriate statistical tools.

Results:

The study included 102 patients, 69 (68%) were females. The mean age of participants was 28 ± 10 and 30 ± 9 years, at symptom and diagnosis onset, respectively. The most common symptoms were motor (n = 63, 62%). Relapsing-remitting course was reported in 96 (94%). Eighty-four patients (82%) had a low disability score (1.5 ± 1.6). Magnetic resonance imaging (MRI) images showed hyperintense white matter lesions, supratentorial (n = 102, 100%), infratentorial (n = 20, 20%), and spinal cord (n = 47, 46%). Half of the patients (50%) underwent MRI with gadolinium, and only four patients showed an enhancing lesion. Visual evoked potential was performed in 61/102 (60%), of whom 37/61 (60%) had optic neuritis. All patients (n = 102, 100%) received treatment with interferon β. The mean value for Vitamin D was 17.25 ± 12.37 ng/ml.

Conclusion:

Newly diagnosed pwMS in the eastern part of Libya is characterized by a mild disability as manifested by a low disability score. Other features are comparable to results from neighboring Arab countries and the rest of the world. Research on regional MS should be improved and facilitated through the establishment of a Libyan MS registry, which will explore data about disease severity and/or progression and the response to treatment.
Assessment of ABH secretor status among voluntary blood donors in a tertiary care hospital of South India
Authors: Thulasiram Nallagondla , Kulkarni Rajendra G. , Sahoo Dibyajyoti
Published: August 2024

INTRODUCTION:

The importance of secretor status is being studied not only to confirm or resolve ABO blood groups for grouping, transplantation, etc., but has become essential for oncologists, dentists, dermatologists, and immunologists, to know the prognosis and outcome of the disease. It also aids in medicolegal aspects immensely with new molecular studies. Testing for secretor has a high value in resolving ABO blood group discrepancies and confirmation of Le (b), Bombay, and para-Bombay groups.

MATERIALS AND METHODS:

This was a prospective cross-sectional analytical study conducted in our blood center for 2 years. The type of sampling was conventional sampling. Secretor/nonsecretor status was determined by hemagglutination test.

RESULTS:

Out of the total 27,014 donors, 318 participants were selected by convenient sampling during the study period. All donors were nonreactive to TTI. In our study, secretors were 229 (72%), and nonsecretors were 89 (28%). The highest secretors were found in the 18-25 age group 77 (24.1%) and weight group 60 - 75 kgs. Seventy one percentage of males were secretor. Among repeat donors 135 (72.9%) were secretors, and in blood groups, ’O’ had majority secretors ie 85 (66.4%).

CONCLUSION:

Testing for secretor status using saliva is a little cumbersome and time-consuming process. It has an important role in any laboratory center for resolving blood group discrepancies, confirming Bombay, para-Bombay blood groups.
A comparison of serological phenotyping and molecular genotyping for Kell, Kidd, and Duffy antigens in multi-transfused thalassemia patients
Authors: Sonker Atul , Dubey Anju , Mohan Yatendra
Published: August 2024

BACKGROUND:

In multi-transfused thalassemia patients, serological phenotyping fails to test patient's actual blood group antigen profile due to the presence of donor red blood cell (RBC) in the circulation. This limitation of serological tests can be overcome by genotype determination using the polymerase chain reaction (PCR)-based methods. The aim of this study is to compare the serological phenotyping of Kell, Kidd, and Duffy blood group systems with molecular genotyping in the normal blood donors and multi-transfused thalassaemia patients.

MATERIALS AND METHODS:

Blood samples from 100 normal blood donors and 50 thalassemia patients were tested using standard serological techniques and PCR-based methods for Kell (K/k), Kidd (Jka/Jkb), and Duffy (Fya/Fyb) blood group systems. The results were compared for concordance.

RESULTS:

Genotyping and phenotyping results were 100% concordant for normal blood donors whereas those for thalassemia patients showed 24% discordance. The frequency of alloimmunization in thalassemia patients was 8%. The results of genotyping were used to provide Kell, Kidd, and Duffy matched blood for transfusion therapy to thalassemia patients.

CONCLUSION:

The actual antigen profile in multitransfused thalassaemia patients can be reliably determined using genotyping. This would benefit in providing better antigen matched transfusion therapy to such patients hence reducing the rate of alloimmunization.
