Authors: Brasil Alexandre Anders , Angelo Humberto , Calderon Rafael de Azevedo , Almeida Alexandre Nascimento de , Paula Maristela Franchetti de
Published: July 2023

The objective of this study is to identify the determinants of Non-Timber Forest Products (NTFPs’) supply and demand in the Amazon region. The method applied was an econometric model of supply and demand in a log-linear form. Based on consumer and firm theories as well as studies on the market for extractive products, we developed models of supply and demand for NTFPs. The models were estimated by Ordinary Least Squares (OLS) in the log-log functional form, allowing to obtain the elasticities of the variables that affect the NTFPs supply and demand. The results indicated that during the study period, the behavior of the NTFPs market was stable in terms of the price and the quantities produced. These products displayed low elasticity in relation to price, both on the supply and the demand sides. This indicates that the cultivation of NTFPs (producing species) is a better option than the expansion of extractive activity. We conclude that the modernization of extractive production, the development of the products, and government support for commercialization are essential for the development of sector and the local community

The reality on the ground shows that students still make mistakes in solving problems in the form of Linear Program stories. This study aims to describe students' mistakes in solving word problems in linear programming material. The method used in this research is descriptive qualitative research. The subjects in this study were class X students of Karya Bahana Vocational School, Bekasi City. The instrument in this study was in the form of 5 questions in the form of descriptions. In addition to the instrument in the form of tests, interviews were used to dig deeper into students' answers to the questions presented. The results showed that the most errors made by students were in the aspect of errors in writing the final answers, and the fewest errors were in the aspects of transformation errors. The cause of reading errors is that students are unable to interpret sentences correctly and cannot find key words and important information. The cause of the error in understanding the problem was that students did not include the known data and the data asked. The causes of errors in the transformation are students not being able to model everyday sentences into mathematical symbols and errors in using mathematical operations. The cause of the process skill error was that the student was unable to write down the objective function and the student was unable to continue with the answer, while the cause of the error in writing the final solution was the inability of the student to draw conclusions correctly.

Published: July 2023

The price of soybean meal in Poland is related with the price quoted on the Chicago Board of Trade (CBOT). The aim of this study was to assess and compare extreme price risk on the market of soybean meal in Poland and on the market of futures contracts for soybean meal and soybean, quoted on the CBOT. For this purpose analyses were conducted on daily price series for soybean meal ex quay port of destination Gdynia as well as historical time series for daily closing quotes for futures contracts for soybean meal and soybean at the CBOT, from 23 February 2012 to 8 July 2015. Extreme risk was assessed using two measures: value at risk and expected shortfall, applying the extreme value theory. Results of analyses indicate a higher level of extreme price risk on the market of futures contracts for soybean meal and soybean. For both contracts we observe an asymmetry of the risk profile for the long and short positions in these contracts. No marked asymmetry in the risk profile was observed on the market of soybean meal in Poland.

Authors: Klusek Tomasz
Published: July 2023

Transformations of the area structure of farms in Poland are determined by various factors among which the ability to acquire land on preferential terms is of critical importance. This thesis is supported, inter alia, by the analysis of sales realized in years 2010-2013 by the Agricultural Property Agency. They would not have been obtained, had it not been for farmer demand supported by the division of payments into installments or subsidizing interest payments on loans by the Agency for Restructuring and Modernization of Agriculture. The circumstances, scale and effects of this type of public aid as related to the creation of new agricultural holdings or enlargement of existing ones, are the subject of this study.
Feeling of Relative Deprivation as a Driver for Higher Agricultural Subsidies
Authors: Poczta-Wajda Agnieszka
Published: July 2023

Because people tend to compare themselves with others from their own surroundings, even a person rich in absolute terms can feel poor in relative terms, if people from their reference group are richer. This phenomenon is called relative deprivation. Farmers in developed economies claim to be poor, because they compare themselves not with farmers from poor economies, but rather with other members of their own society who work outside of agriculture and whose incomes are usually higher. Feeling relatively deprived, farmers in developed economies demand stronger financial support and act intensively to convince policymakers to support them. The main aim of this paper is to analyze the relation between relative deprivation of farmers and support for farmers in countries with different development levels. Results of this study prove that levels of support for farmers are positively related with the average level of relative deprivation of farmers dependent on the size of farmer groups. Hence the idea of relative deprivation might provide additional political explanation of different levels of support for farmers in countries with different development levels.
Correlations between Fragmentation of Farms in the Republic of Moldova and its Impact on Farm Incomes Compared to Poland and Romania
Authors: Popa Daniela , Dinu Toma
Published: July 2023

The paper presents selected problems of farm management in terms of fragmented agriculture. The problem of land fragmentation was exemplified in these three countries of Central and Eastern Europe. The main purpose of the study was to compare the effectiveness of selected indicators of agricultural production in the three selected countries. For the analysis, the data on the concentration indexes was selected from: Lorenz concentration coefficient, the Gini index, and territorial concentration coefficient (Gini C and Stuck formula). In selected countries, there are a large number of small and very small farms. They represent the majority of farms managed by private owners. To a large extent, they are called semi-subsistence farms or social farms. Some of them provide part of their products on the market. Small farms are part of the so-called European Model of Agriculture – a model that consists of small family farms. It is difficult to indicate a correct definition of “small farm”, as it may be defined differently depending on the region or country. In the EU, small farms occupy a dominant position, being a constant subject of debates and policy. The authors of the article stressed the need for strengthening the small farm position, for example by enlarging their acreage or by initiating horizontal or vertical cooperation in a way that shall not impair the role of small farms. They are important in biodiversity protection, preserving the rural landscape, as well as maintaining local tradition, culture and heritage.

Authors: Ge Zhengxi , Xin Zilong
Published: July 2023

To revitalise established urban areas in the context of stock planning, the river surges in established urban areas play an irreplaceable role. In recent years, the water systems of rivers and surges in established urban areas of many international metropolises have undergone transformation and regeneration. The formerly hardened river banks have begun to be transformed into post-industrial places of integrated residence, leisure, and work, reshaping the ecological landscape and the functions of leisure activities of the rivers and urban spaces. By selecting typical representative cases for analysis and research, this paper determines the research angle and conducts a comparative study of waterfront open space in small and medium-sized cities and large cities from the perspectives of spatial layout, functional structure, ecological restoration, and artistic style, summarises the characteristics and current problems of waterfront open space in small and medium-sized cities at the present stage, and takes the problem as a guide, combining urban design, place theory and other theoretical studies as a guide. Planning and design strategy for waterfront open space in small and medium-sized cities is proposed. This paper selects representative waterfront open spaces and open waterfront spaces for field research. It uses the waterfront open space planning strategy proposed in the paper as a guide to provide a basis for waterfront open space planning and design and, at the same time, selects typical lots for optimal design to verify the implementation ability of the strategy. This paper digs into the rich historical, and geographical information contained in the sample villages in each area summarises the site selection characteristics of traditional villages in Hebei at the mesoscopic level between different areas and analyses the characteristics of the overall layout of villages dominated by natural factors such as mountains, hills and plains, and human factors such as ancient defile post roads, military defences, industries and temples. The spatial skeleton structure of the single-axis type, multi-axis type, organic network type, regular network type, and the fortress-wall enclosed village is extracted. The characteristics of its subtypes are summarised with sample cases. The elemental composition of village centres and boundaries is summarised.

From 10–19, adolescence is a transition from childhood to adulthood. There will be changes in the shape and function of the body in a reasonably short time. Sufficient and adequate nutrition for adolescents is one factor affecting their reproductive health. This community service aimed to monitor nutritional status and detect early signs of Chronic Energy Deficiency (CED). Monitoring of nutritional status is carried out for adolescents, especially young women. Physical health and healthy reproductive organs are essential in preparation for becoming healthy expectant mothers who can later give birth to a healthy generation. Holistic health education was needed in adolescents' growth to become better human beings in terms of their health. This activity was carried out in May 2023 at Junior High School, YPI Ciparay, and Bandung Regency. The target audience was young girls in 7th grade; there were 82 people. At the time, the students filled out questionnaires about their characteristics. Then the team measured the anthropometrics to determine the nutritional status and the incidence of CED by weighing, measuring height, and measuring upper arm circumference. The measurements showed that the nutritional status based on body mass index for most female students was standard, about 60.97%, and 41.46% of female students were CED. Counselling and health information were also provided holistically to increase the girls' understanding of their health status.

Published: July 2023

The US Environmental Protection Agency is revising its policy on drinking water quality reports for consumers. These reports are intended to enhance the public’s “right to know” and to spur action to protect and promote safe water. However, these reports are known to be highly technical and difficult to access compromising their communication value. This study engaged a focus group to gather evidence on how these reports can be improved. We applied user-centered design principles to understand public drinking water consumer information needs and preferences and to develop new communication tools and methods. Through a set of in-depth interviews, we learned that most participants were unaware of the report until introduced to it during the study. The focus group participants voiced preferences for: better ways to convey technical information; more health information; a clearer understanding of costs and billing; and neighborhood or household level water quality information. Following the interviews, we convened two rounds of small group meetings to create new report designs and to review and refine the designs. The focus group developed a one-page summary statement, water contaminant trend charts, an interactive map, and other recommendations on ways to improve dissemination of the report. The project results, focus group recommendations and designs were submitted to the US Environmental Protection Agency for consideration as the policy for these reports is finalized. We believe these findings provide valuable insights into water quality communication challenges that are widely applicable and will be informative for water utilities as they prepare future reports.
An adjoint-based optimization method for jointly inverting heterogeneous material properties and fault slip from earthquake surface deformation data
Authors: Puel Simone , Becker Thorsten , Villa Umberto , Ghattas Omar , Liu Dunyu
Published: July 2023

Analysis of tectonic and earthquake-cycle associated deformation of the crust can provide valuable insights into the underlying deformation processes including fault slip. How those processes are expressed at the surface depends on the lateral and depth variations of rock properties. The effect of such variations is often tested by forward models based on a priori geological or geophysical information. Here, we first develop a novel technique based on an open-source finite-element computational framework to invert geodetic constraints directly for heterogeneous media properties. We focus on the elastic, coseismic problem and seek to constrain variations in shear modulus and Poisson's ratio, proxies for the effects of lithology and/or temperature and porous flow, respectively. The corresponding non-linear inversion is implemented using adjoint-based optimization that efficiently reduces the cost functional that includes the misfit between the calculated and observed displacements and a penalty term. We then extend our theoretical and numerical framework to simultaneously infer both heterogeneous Earth's structure and fault slip from surface deformation. Based on a range of 2-D synthetic cases, we find that both model parameters can be satisfactorily estimated for the megathrust setting-inspired test problems considered. Within limits, this is the case even in the presence of noise and if the fault geometry is not perfectly known. Our method lays the foundation for a future reassessment of the information contained in increasingly data-rich settings, e.g. geodetic GNSS constraints for large earthquakes such as the 2011 Tohoku-oki M9 event, or distributed deformation along plate boundaries as constrained from InSAR.
Depression Across Cultures: Exploring Cultural Variations in the Experience, Expression and Treatment of Depression
Authors: Krishnan Srikar , Ashokkumar Chiraag
Published: July 2023

Objective: This abstract aims to critically examine the impact of cultural and cross-cultural variations on the prevalence, presentation, and treatment of depression to identify the cultural factors that contribute to diverse experiences of depression. Introduction: Depression is a complex mental health condition with variations across cultures and societies. Cultural and cross-cultural factors influence how depression is experienced, expressed, and understood by individuals. Understanding these cultural variations is essential for providing culturally sensitive and effective interventions to address the diverse needs of individuals experiencing depression worldwide. Method: The following data were obtained by using keywords such as “depression,” “culture,” and “cross-cultural variations” on google scholar, and 25 research papers were reviewed for the obtained information. Result: Comparing older adults in the United States with elderly individuals in Oriental societies reveals higher mean depressive symptom scores among the former. Significant depression prevalence varies across living situations: 0.9% to 9.4% in private households, 14% to 42% in institutional living, and 1% to 16% for elderly in private households or institutions. Clinically significant depressive symptom cases range from 7.2% to 49%. Predictors of depressive disorders include female gender, somatic illness, cognitive and functional impairment, lack of social contacts, and a history of depression. Racial discrimination and stigma may lead to under-diagnosis in Afro-American populations, while White Western populations may experience potential over-diagnosis due to cultural norms. These findings emphasize the importance of considering cultural factors and addressing biases in diagnosing and treating depression in diverse populations. Discussion: This abstract highlights the importance of considering cultural and cross-cultural variations in understanding depression. Cultural factors significantly shape an individual’s experiences, expressions, and perceptions of depression, influencing its prevalence, manifestation, and treatment outcomes.Through the recognition and respect of cultural diversity, the development of more effective and culturally sensitive approaches to address depression can be achieved. Further research is needed to explore the intricate interplay between cultural contexts, individual beliefs, and social norms to ensure the development of comprehensive and inclusive mental health interventions. Improving mental health outcomes on a global scale necessitates the embracing of cultural variations as an essential factor.
Evaluation of the Scales for Social Comparison of Appearance (SSC-A) and Social Comparison of Well-being (SSC-W)
Authors: Morina Nexhmedin , Meyer Thomas , McCarthy Peter , Hoppen Thole H. , Schlechter Pascal
Published: July 2023

People constantly compare their appearance and well-being to that of other individuals. However, there is a lack of a measure of social comparisons of well-being, and existing appearance-related social comparison scales assess social comparison tendency using predefined social situations. This limits our understanding of the role of social comparison in self-evaluation and well-being. Therefore, we developed the Scale for Social Comparison of Appearance (SSC-A) and the Scale for Social Comparison of Well-being (SSC-W) that assess downward and upward social comparisons with regards to a) frequency, b) perceived discrepancy, and c) affective impact during the last three weeks. In one longitudinal and three cross-sectional studies with sample sizes ranging from 500 to 1,119 participants, we administered the SSC-A or the SSC-W alongside measures of appearance social comparisons, body satisfaction, self-concept, social rank, psychological well-being, envy, rumination, depression and anxiety. Confirmatory factor analyses supported the expected two-factor solution representing upward and downward social comparisons for both scales. Their validity was supported by significant associations with the measured constructs. Overall, upward comparisons displayed higher associations with most measured constructs than downward comparisons. The SSC-A and SSC-W offer parsimonious, reliable and valid measures of social comparisons of appearance and well-being.

Published: July 2023

The archive of famous Soviet Ukrainian cinematographer Leonid Burlaka is an example of photography illustrating various spheres of life in Ukraine from the 1960s to the 1990s and has not only historical but also artistic value. In March 2017, the missing part of Leonid Burlaka’s photo archive was discovered in Odessa (Ukraine). Accordingly, the first phase of research was devoted to the analysis of the history of archive discovery, its condition, contents, and the systematization of photographs constituting the archive. In the second stage of the research, another part of the archive was analyzed, which was not lost but preserved by Leonid Burlaka himself and totaled over 300 films. In the process of exploring, the archive raised numerous new issues. How will the further life and preservation of the archive look? What might be the experience of presentation of the archive, its involvement in artistic practices and its influence on collective perception in the post-Soviet period? Currently, the archive forms the basis of the interdisciplinary project Fragile Memory. Therefore, the article touches on several issues: the history of the archive, questions regarding its research, as well as the experience of its popularization, which has been conducted during the past five years within the framework of the Fragile Memory project.

Published: July 2023

In order to bring intralogistics systems to the same level of interoperability as today’s modern production systems, logistics must take the essential steps towards Industry 4.0. This requires an increasing abstraction level of control logic as an enabler for horizontal and vertical integration. The abstraction will lead to the interconnection ofmanufacturing and logistics control with the production planning and warehouse management systems (WMS). A main enabler for these communication paths are service-oriented architectures (SoA). OPC UA has established itself as a widely used and already adopted SoA-based communication standard in industry. The paper describes the realization of an OPC UAbased approach for the communication between a WMS and a PLC of an automated storage and retrieval system (ASRS). The conceptual basis of communication design are skills of the ASRS. The work is supported by an architectural design with a subsequent prototypical implementation.

Objective: To identify the morphological and biochemical variations of achacha (Garcinia humilis (Clusiaceae) (Vahl) C.D. Adam) in three ripeness stages of consumption.
Design/Methodology/Approach: The morphological and biochemical variables of fruits in three ripeness stages were evaluated to identify the preferred stage for consumption. We collected 15 fruits from 10 productive-stage trees (n=150) for each ripeness stage for their subsequent evaluation in the laboratory. The morphological and biochemical variables were evaluated in each one. Each fruit was considered an experimental unit. The morphological and biochemical variables were evaluated for each unit.
Results: Delaying the harvest for a few days increases the weight, length, diameter, and pulp:seed ratio of the fruits and decreases the firmness of the epicarp and the acidity. The °Brix increases and the fruits lose a considerable weight during storage. The pulp of the ripest fruits had light and unsaturated colors.
Study Limitations/Implications: Changes in the conditions of the production systems and the variation in the availability of rainwater throughout the year and from one year to another can cause variation in fruit quality.
Findings/Conclusions: The ripest fruits had outstanding biochemical parameters for its consumption and better morphological characteristics (length, total weight, diameter, and pulp:seed ratio). With adequate training, the results enable the color of the epicarp and the pulp variables to be used as a harvest index.

Objective: to determine if the economic crises of 1994 and 2008 and the health crises of 2009 and 2020 affected the relationship between the main price and the production of agricultural products in the states that have the highest production in the regions of the agricultural sector of Mexico.
Design/methodology/approach: sixty structural stability tests were carried out with dummy variables, to analyze the effect of these crises on the price-quantity relationship of the main producer States of the five regions of the agricultural, sector of the main products produced in Mexico that they are grain corn, grain sorghum and beans.
Results: the economic crises of 1994 and 2008, as well as the health crises of 2009 and 2020, in general (with some exceptions), did not impact the relationship between price and production in the main producing States of the five regions of the sector agriculture of Mexico of the main products produced in Mexico.
Limitations on study/implications: not all products and all states of Mexico are examined.
Findings/conclusions: economic and health crises, in general, do not disappear from the relationship between the price and production of the States and producers analyzed, that the price-production relationship of these is resilient in the face of economic and health crises, that is, producers do not significantly alter their production, given the price variations caused by the economic and health crises.

Vertical space use informs the ecology and management of marine species, but studies of reef-associated sharks often focus on horizontal movements. We analysed the vertical movements of silvertip sharks Carcharhinus albimarginatus using pop-up archival tags deployed on 7 individuals in the Chagos Archipelago, central Indian Ocean. The sharks changed depth predictably with water column thermal structure, moving deeper with seasonal increases in mixed layer depth while occupying a narrow ambient water temperature range around ~27°C. At shorter timescales, higher resolution data from 5 tags showed that silvertip shark depth varied cyclically with surface light levels, increasing during daylight and on nights around the full moon. This matches the diel vertical migrations of many fish species, suggesting that the sharks’ light-driven depth changes might relate to foraging. While most vertical movements (>98%) were within the mixed layer, deeper dives to 200-800 m occurred approximately every 3 d. High-resolution data from one recovered tag showed the shark ascending deep (>200 m) dives in 2 sharply defined phases, initially fast then slow. Analysis of dive profiles against dissolved oxygen (DO) data suggested that the shark may have ascended rapidly to escape low DO levels at depth, then reduced its ascent rate by 50-80% once DO levels increased. While a small sample, the electronic tags deployed in this study revealed the silvertip sharks’ predictable use of mixed layer waters, narrow thermal range and apparent intolerance of hypoxic conditions. These characteristics may exacerbate the species’ vulnerability as oceanic warming and shoaling oxygen minimum zones modify vertical habitat availability.
Rethinking Public Opinion in the Digital Era: Towards a Post-representational Theory
Authors: Lock Matheus
Published: July 2023

The quasi-ubiquity of ICT is transforming contemporary politics and seems to deteriorate democracy, for the technologies undermine debates, contest the grounds of reason and truth, and influence people’s votes. Donald Trump’s election and Brexit are good examples of their effects on public opinion. More fundamentally, these technologies cause theoretical problems to the way we traditionally conceive public opinion. Thus, I seek to rethink public opinion beyond conventional approaches. Departing from Deleuze and Guattari’s work, I develop the first steps of a post-representational theory of public opinion as a regime of political truths that has new dimensions of truth production with information and communications technologies.
Ecology of the Virtual
Authors: Pál Pelbart Peter
Published: July 2023

Félix Guattari mentioned an ‘ecology of the virtual’. This notion is developed in this article along two dimensions. The first dimension, which is conceptual, relates the mental or subjective ecology of The Three Ecologies to the ‘functors’ of Schizoanalytic Cartographies. The other dimension takes into consideration today’s context in Brazil, especially Amerindian struggles. I focus on how Guattari’s thinking of the virtual, in dialogue with other contemporary authors, opens the way to heterogenetic processes, with their own ecopolitical consequences.

Digital contact tracing presents numerous advantages compared to manual contact tracing methods, especially in terms of enhanced speed and automation. Nevertheless, a lack of comprehensive evaluation regarding functionality, efficiency, benefits, and acceptance within communities remains. Here we primarily focus on the functionality of THEA-GS, an open-source digital contact tracing tool developed through consultation with stakeholders. Additionally, we provide insights from its implementation on a limited sample of haulage drivers in Uganda, serving as a representative case for a low- and middle-income country. THEA-GS comprises two primary components: (a) a smartphone application, and (b) a suite of server-programs responsible for data processing and analysis, including databases and a web-based interface featuring dashboards. In essence, the mobile application records the timestamped location of haulage drivers within the road network and identifies possible transmission hotspots by analyzing factors such as the duration of stops and the communities associated with them. The tool can be integrated with national infrastructure to compare drivers’ diagnostic results and contact structure, thereby generating individual and community risk assessments relative to the road network. During the Omicron-variant wave of the COVID-19 pandemic, a total of 3,270 haulage drivers were enrolled between October 2021 and October 2022. Around 75% of these drivers utilized THEA-GS for approximately two months. Based on an analysis of 3,800 test results, which included 48 positive cases, 125 contacts, and 40 million time-stamped GPS points, THEA-GS shows a significant speed improvement, being approximately 90 times faster than MCT. For instance, the average time from sample collection to notifying a case and their contacts was approximately 70 and 80 min, respectively. The adoption of this tool encountered challenges, mainly due to drivers’ awareness of its purpose and benefits for public health. THEA-GS is a place-based digital contact tracing tool specifically designed to assist National Public Health Institutions in managing infectious disease outbreaks involving the haulage industry as a high-risk group. While its utility, acceptance, and accuracy have not been fully evaluated, our preliminary tests conducted in Uganda indicate the tool’s functionality is robust, but social acceptance and adoption are heavily reliant on establishing trust among users.
