Keeping Land in Grass: Re-Enrollment Motivations with the Environmental Quality Incentive Program after the Conservation Reserve Program
Authors: Harp Aaron J. , Maczko Kristie
Published: June 2024

We present data from producers in the upper Great Plains of the US for whom at least one Conservation Reserve Program (CRP) contract expired in the last seven years. The survey covered two groups, one with a retired CRP contract and a second with a retired CRP contract who then enrolled in the Environmental Quality Incentives Program (EQIP) program. Most respondents at least tried to re-enroll into CRP, many unsuccessfully. The CRP group primarily moved to crops on the former CRP land, while EQIP respondents focused on cattle and grazing. Awareness of the EQIP program on the part of the CRP group was only 58%. We compared groups regarding what they considered doing with the land at the end of their respective programs, CRP and EQIP. We examined group differences in motivations and attitudes and found evidence of convergence. We also evaluated these differences using effect size statistics to determine their importance to our overall questions. Our overall conclusion is that the groups have a long history of program participation and there is little difference between them in both their motivation to participate and willingness to do so in the future.

Amelioration of Flexural Performance for Reinforced Concrete Beams by Soffit Bonded High Performance Self Compacting Concrete Prisms
Authors: Yas Shiemaa Taha , Al-Hadithy Laith Khalid
Published: June 2024

This paper presents a strengthening technique using a high-performance fibre-reinforced cement-based composite (HPFRCC) mixture. To evaluate the performance of this approach, two types of concrete mixtures were used one high performance and other high strength in strengthening process and compared to strengthening using CFRP laminate. The results showed that the strengthening was in the proportions (42 %, 58.03 %, 74.32 %) for (Mhs, Mcfrp, Mhp), respectively, Where the strengthening improved the bending capacity for beam (Mhp) to a greater extent of the other types and it reduced the appearance of cracks in the beam when loading until occur failure. As appeared failure modes in all elements were due to rupture in the flexure region and crush in the compression region. In addition, ductility index of the strengthened beams was acceptable and energy absorption of the strengthened samples high if compared to the reference beam Therefore, it can be said that this technology may provide a safer alternative for flexural strengthening of RC beams.

Published: June 2024

In order to ascertain how explosive load influences orthotropic slabs with short span stiffeners partially positioned in the x-direction, the purpose of this study is to perform a numerical analysis. The maximum displacement of a floor surface with respect to the force of an explosive load and the angle of inclination. It is feasible to calculate the impact of the angle of inclination and the height of the blast load on the vertical deflection of the slab using the 6th order polynomial blast equation, as long as the local blast load is positioned in the center of the slab. An analysis reveals that the vertical deflection of the slab is affected by the timing of the explosion. Specifically, a more powerful explosion has a diminishing effect on the deflection of the slab. The inclination angle has no major impact on the outcomes of deflection.

Authors: Kareem Abbaas I. , Khaled Teba Tariq , Aljubory Ahmed , Al-Hamd Rwayda Kh. S. , Isaac Darren
Published: June 2024

It is commonly known that mineral fillers significantly affect the asphalt mixture's performance. Superior flexible pavement performance can be ensured by gaining a deeper understanding of the function of filler. This research investigates the influence of three different fillers: granite dust, cement, and hydrated lime, at Australian asphalt mixtures. The testing program includes Marshall testing, moisture damage resistance, indirect tensile strength (ITS), and indirect tensile stiffness modulus (ITSM) tests of asphalt mixtures. Analysis of variance (ANOVA) was used to statistically assess the results obtained, besides damage analysis. The results indicate that using natural granite dust yields the highest resistance to moisture, while cement produces the highest stability, ITS, and ITSM. Unexpectedly, using hydrated lime filler decreases the stability/stiffness and moisture resistance of asphalt mixtures. ANOVA tests indicate that the type of filler affects ITS, TSR, and ITSM results (i.e., the p-value <0.05). The damage analysis shows that the design life of the asphalt mixture made with cement filler is higher than that of mixtures made with natural granite dust and hydrated lime fillers respectively. The findings indicate the important role of nontraditional fillers at the performance of Australian asphalt mixtures.

Authors: Wibawa I Made Sastra , Maharani Shinta Enggar
Published: June 2024

Clay soil processing using cement is widely done but it is difficult to find studies that fit this topic, because the case study conducted is on the famous transportation route, namely Jalan Kuta – Tanah Lot in Bali, Indonesia. Pavements at this location are often damaged. In the dry season the road here is often cracked, while in the rainy season there is a decrease in certain parts or potholes occur that endanger users. Therefore it is necessary to conduct an analysis. This research aims to obtain the right formula of the ideal mixture of cement and clay, through mechanical tests i.e. compressive strength. Some results that are in accordance with the research conducted have been contained in the literature review, especially density and compressive strength testing. The use of cement as a stabilizer in clay is successful, as well as for other types of soil. The method used is soil sampling directly at the site, then mixed cement with various variations (treatment). This study discusses the success of cement to stabilize clay soils, especially increasing compressive strength and decreasing plasticity index. According to the results obtained that using cement as a soil stabilizer shows significant strength results, especially in ideal mixtures. This research is believed to be able to answer the obstacles that exist in clay soils to function as sub grade.
Comparison Between the Behavior of Reinforced Concrete Beams and RPC Beams Under Bending and Torsion Moments
Authors: Delphi Hanan R. , Sultan Wisam H. , Zghair Luma A.
Published: June 2024

Typically, the beams were subjected to bending and torsion moments especially at building edge. However, most of the studies focus on the flexural or torsional behavior of the beams independently, and few studies investigated these two combined effects. The research intends to explore the structural behavior of eight 1500mm x 200 mm x 150 mm rectangular beams that were tested under the combined effects of bending and torsional moments, with four main values of (T/M) ratio: pure bending, pure torsion, and two combined cases. The research investigates the effect of using reactive powder concrete (RPC) on beam behavior compared to normal concrete (NC). The outcome demonstrates that using RPC in beams instead of NC beams will significantly increases the cracking capacity by 136.4% in the case of pure bending and significantly increases the ultimate capacity by 118% in the case of combined moments with (T/M = 1). Also, using RPC leads to significant reduction in deflection and rotation values especially after beam cracking. RPC reduces compressive concrete strain and values of strains in longitudinal and transverse reinforcement especially in advanced loading stages.

Green building’s development reduces the reliance on fossil fuels and reduces the total negative environmental effect. The main objective of this research is to develop a model for the implementation of green practises in the public sector constructions in India. We aimed to assess local construction professionals' knowledge and comprehension of green building construction in the public sector by distributing an empirical questionnaire to them. Participants were asked to rate their knowledge, understanding, and importance of the eight withholding factors and six contributing factors identified in the seminal literature. We use analysis techniques like descriptive and factor analysis such as descriptive and factor analyses to analyse the survey responses. A comprehensive model proposed to facilitate the purpose of promoting the successful adoption of green building practises within India's public sector construction projects was primarily based on the insights gained from factor analysis. Based on the findings of this study, the author suggests a model for implementing green building techniques in Indian public sector constructions. The model discusses obstacles to green building initiatives, considers implementation variables, and offers suggestions such as policy ease, and green building promotion.
An Experimental Study of the Frictional Behavior at the Interface Soil-Structure with Regards to Wall Friction Effect and Clogging Related to Surface Roughness Form
Authors: Djaafri Djamel Eddine , Nouaouria Mohamed Salah
Published: June 2024

The interactions between soil-structure are largely governed by the shear strength at the soil-structure interface, particularly in situations involving large displacements, known as shear residual strength. This latter can be influenced by a range of factors, including normal stress, physical properties, surface roughness, wall friction. The main objective of this study is to investigate clogging related to surface roughness form, in addition to wall friction arises from consolidation. In order to investigate the impact of wall friction, experiments involving ring shear tests were carried out on kaolin. Four different consolidation durations were employed to induce varying settlements of the upper platen, while three distinct testing procedures, including single stage, multistage, and preshearing, were utilized. Additionally, different levels of surface roughness were incorporated to investigate the effect of clogging. The test results obtained from various testing procedures indicate that employing a single stage procedure with zero consolidation time is the most suitable approach for mitigating the influence of wall friction. For clogging effect, is dependent on the materials used, namely, the kaolin and the mixture, as well as, the interfaces involved.
Dual Cultural Influence on the Architectural Style Evolution of San Francisco Chinatown: A Comprehensive Examination
Authors: Yang Ziyuan
Published: June 2024

The unique neighborhood style of San Francisco Chinatown is influenced by Chinese and American culture, history and social system. Through field investigation, Chinese and English literature collection, and spatial analysis, this paper interprets the motivation of its style evolution. In the process of research, the author tries to analyze the changes and driving forces of Chinatown in San Francisco from three dimensions: the city scale, the blocks scale, and the building scale. The results show that the formation process of Chinatown in San Francisco and the range of its blocks are deeply influenced by the world political pattern in the early 20th century, the Sino-American multi-party regulations and Sino-American relations. The architectural style of the block is influenced by the Eastern and Western cultures, which is a distinctive architectural feature. The traditional architecture is deeply influenced by the architectural style of southern Fujian, while the new architecture is mainly based on the modernist architectural style. Among the main factors affecting the evolution of Chinatown in San Francisco, gold rush, earthquake, traditional Chinese architectural style and immigration policy to China are the internal mechanisms of the formation of Chinatown’s spatial characteristics.

Published: June 2024

In recent years, CFRP is the most popular material in strengthening RC members (columns, beams, slabs…etc.) as well as the textile-reinforced mortar (TRM) was also used as an alternative method for strengthening RC columns. The present study includes fifteen circular RC columns: One control column, ten columns strengthened by one or two layers of CFRP using EBR or EBROG methods, two columns was strengthened by textile-reinforced epoxy on grooves and last two columns were strengthened by textile reinforced mortar without grooves. The parameters of this investigation are type of strengthening technique (EBR, EBROG and TRM), number of CFRP layers, and the grooves configuration. The results showed that the columns strengthened longitudinally with one or two layers of CFRP strips using EBR technique enhanced the load-carrying capacity by 2 and 7.13%, respectively, when compared with control column. However, the load carrying capacity of RC columns strengthened by EBROG increased by the range of 11.65% to 71.4%. in comparison with control column. Finally, TRM strengthening method enhanced the load carrying capacity by about 21% to 58.5%. Also, the results showed that the EBROG and TRM approaches were improved the stiffness and ductility of the columns in comparison with EBR method.

Published: June 2024

The Pacitan Regency of Indonesia is located in an area of high seismic activities. Regrettably, field surveys held in Pacitan Regency, Indonesia have revealed the prevalence of low-income housing structures that do not meet the engineering standards and are vulnerable to damage during earthquakes. The seismic evaluation of these buildings is urgently required. This study proposes realistic damage state limit values for the seismic damage evaluation of non-engineered buildings. For this purpose, an incremental dynamic analysis was conducted on a sample of non-engineered buildings in Pacitan to evaluate their probable seismic damage. As a result, curves showing the dynamic pushover responses of buildings to various input earthquakes were plotted. These curves were then summarized as three-linear curves, providing a single value for the average response of the structure. Based on this simplified curve, a more realistic damage-state limit for non-engineered structures are proposed. The damage levels of slight (DS1), moderate (DS2), extensive (DS3), and complete (DS4) were determined using the drift ratio at the linear elastic limit, midway point between the linear elastic and yield limits, yield state, and 80% rupture limit, respectively.
Effects of Soft Story Locations on the Nonlinear Time History Analysis of Multistory Reinforced Concrete Buildings
Authors: Ibrahim Teba Salim , Mohamad Halla Jasem
Published: June 2024

The current paper included studying the effects of soft storey locations on dynamic response of reinforced concrete (RC) buildings under the impacts of earthquakes. Soft storey is essential to provide the building with a functional space such as vehicle garages or open meeting rooms. Further analytical investigation was necessary to understand the impact of these flexible floors on the building's response during earthquakes, as conducting experimental research to address this issue is highly difficult. The research encompassed the effects of soft storey location in two types of buildings, one with equal spans and the other with unequal spans, on the nonlinear time history response. Each building consists of a 10-stories (G+9) RC residential structure subjected to earthquake effects. The analysis was carried out using program sap2000 v23. An analogous diagonal strut was used to illustrate the infill panels. The study included the effect of soft storeys on the natural period, the change in base shear with time, and the change of displacement and acceleration along time for each building. The obtained results showed that including a soft storey in the analysis for buildings having either equal or unequal spans increased the time period, displacement, and storey drift, causing a decrease in the acceleration and base shear forces. Building with the soft storey on the fifth floor (at the mid-height of the building) showed a better dynamic response compared with that using the soft storey on the ground and last floors.

Published: June 2024

Objective

This study aimed to assess breast cancer (BC) awareness among reproductive women in low- and middle-income countries (LMICs), identify influencing factors, and propose feasible interventions or programs.

Methods

We followed a 5-step process using a modified version of Arksey and O’Malley framework methodology. A comprehensive search was conducted on the Embase, PubMed, and CINAHL electronic databases for literature published within 10 years (from 2012 to 2022).

Results

Thirty-three papers published between 2012 and 2020, spanning 18 countries, were included. Of these, 45.6% described a good level of knowledge, while 24.2% reported that women at reproductive ages had good awareness. Twelve influencing factors were identified in 3 categories: socio-demographic (family history, personal history, marital status, age, religion, income status, living place, and occupation), personal (self-efficacy, education, and perceived level), and external (advertisements promoting awareness). Educational programs were recommended in most (>72%) of the included studies.

Conclusions

While most studies reported high levels of knowledge and awareness, some found low prevalence among certain groups. Factors affecting knowledge and awareness were classified into socio-demographic, personal, and external categories, with socio-demographic factors such as age, education, income, and marital status being the most frequently cited. The studies recommended implementing educational programs, health prevention strategies, and social interventions to increase BC knowledge and awareness

Authors: Mulhaeriah Mulhaeriah , Sangkala Mohammad Syafar , Syahrul Syahrul , Wahyuni Rezki
Published: June 2024

Objective

This study aimed to determine the effect of the relaxation breathing exercise (RBE) on fatigue and cortisol levels among Indonesian women with gynecological cancer undergoing chemotherapy.

Methods

This pilot study consecutively recruited 44 gynecological cancer patients to receive RBE (22) or usual care (22). Cortisol level was measured before and after completion of the intervention (day 8). Fatigue was measured using the Piper Fatigue Scale (PFS). Anxiety and depression were assessed using the Hospital Anxiety and Depression Scale (HADS) at the baseline days of the study for days 1, 4, and 8. The obtained data were analyzed using Fisher’s exact test, the independent t-test, and the Mann–Whitney U test.

Results

There were significant increases in cortisol levels within the groups, either the intervention or control groups, respectively (P-value = 0.0003 and 0.001). Despite there being no statistical significance between the intervention and control groups, there were noticeable differences in the cortisol levels, indicating the extreme increase in cortisol levels in the control group (Median [IQR1– IQR3]: 2.30 [0.99–9.09]; Min–Max: 0.43–23.38) compared with the intervention group (Median [IQR1–IQR3] = 2.97 [1.26–5.18]; Min–Max = 0.39–6.91).

Conclusions

RBE helps prevent a significant increase in cortisol levels that can alleviate fatigue for women with gynecological cancer. Further research was recommended to compare several intervention modalities for fatigue and cancer-related symptom management based on cortisol level changes.

Humanity at the Crossroads. to “Uninstall” Artificial Intelligence or to Invest More in Artificial Intelligence
Authors: Dinicu Anca , Iancu Dumitru
Published: June 2024

The answer to the dilemma in the title is evident: artificial intelligence cannot be decommissioned, just as states or multinational corporations will continue to invest in artificial intelligence. This paper, far from having a technical approach due to considerations related to the competence of the authors, actually aims to highlight the now immutable character of artificial intelligence through the spectrum of the indisputable benefits it generates in the most varied fields of activity, excluding, however, the thaumaturgic character promoted by the apostles of technology. It is an analysis of democracy marked by the intervention, if not sometimes the intrusion, of artificial intelligence, but also a review of the attempts to regulate artificial intelligence precisely so as not to cancel the progress made by the democratic evolution of society, with concrete reference to human rights.

Authors: Frunzeti Teodor , Dumitru Alexandru-Cosmin
Published: June 2024

The swift rise of virtual currencies (VCs) as financial instruments has raised concerns about their ability to increase risks in the global financial system, especially given the current geopolitical instability. This article examines the connection between virtual currencies and financial security, highlighting the importance of strong economic and financial institutions and mechanisms to ensure the reliability of digital assets. We investigate through an extensive literature analysis the various risks linked to VCs, including market volatility, regulatory inconsistencies, and security vulnerabilities, which are exacerbated by geopolitical conflicts. We then examine how institutions have responded to these concerns, focusing on the proactive actions taken by international organizations and national authorities to reduce possible disruptions. The focus of our paper is the Markets in Cryptoassets (MiCA) law, an innovative legislative framework created by the European Union to standardize VC regulation among member states. We analyse the goals and main provisions of MiCA to evaluate its ability to establish an international benchmark for overseeing virtual currencies, ultimately improving investor safety and market integrity. The paper concludes by discussing the changing role of VCs in the geopolitical sphere and supports flexible and cooperative regulatory strategies to balance the advancement of digital assets with financial security needs.

Authors: Boukessessa Meriem , Ghazli Abdelkader , Ali-Pacha Adda
Published: June 2024

The demand for scalable, open and granular networks has enabled mobile networks such as 5G to adopt new concepts including NFV (Network Function Virtualization). NFV separates the dependency of network functions from the hardware component, allowing them to be deployed flexibly and dynamically across network slices. In this way, operators can deliver personalized services and optimize the use of network resources, contributing to greater operational efficiency and an enhanced end-user experience. However, there are several issues to be addressed, such as the security of VNFs and the way in which service provider customers instantiate NSSIs (Network Slice Subnet Instance). In this article, we present a new approach based on blockchain 2.0, which guarantees the immutability of VNFs and templates, as well as highly secure instantiation with access management and support for replay attacks.

Objective: The objective of this study is to investigate the implementation process of ecotourism, with the aim of understanding the different forms of knowledge generation and learning in a company with precolonial references.
 
Theoretical Framework: This topic presents the main concepts and theories that support the research through the critical perspective of Organizational Studies. The binomial knowledge-organizational learning stands out, providing a solid foundation to understand the context of the research.
 
Method: The methodology adopted for this research includes a case study based on a qualitative approach with a phenomenological approach. Interviews were conducted with members of the organizations and advisors who supported the implementation of the ecotourism model. Data collection was carried out through semi-structured interviews, participant observation and document analysis. Data were analyzed with an interactive model using an inductive approach.
 
Results and Discussion: The results obtained revealed the influence that the origin and ownership of the land has on the process of conception and practice of ecotourism. In the discussion section, cooperation between community members stands out as essential in the management of knowledge and learning, and the achievement of organizational objectives.
 
Implications of the research: These implications could cover the theoretical-methodological limits to understand these organizational forms that live between premodernity and modernity and the need to generate sustainable reproductive, consumption, distribution and maintenance systems. Organizational Studies present a critical vision in the analysis between the complementarities and contradictions that underpin the implementation and practice of ecotourism.
 
Originality/Value: This study contributes to the literature by exposing the nature of this type of organizations with precolonial references where ecotourism merges with the traditions, rituals and worldviews of the community, exposing tensions and paradoxes of an organizational model that incorporates contradictory elements and at the same time complementary, such as sustainable development. The relevance and value of this research is evident in understanding the knowledge-learning process from the perspective of the subjects and the practical application in the implementation of ecotourism based on the nature of land ownership.

En este artículo recuperamos y ampliamos nuestras lentes sobre la experiencia de investigación en diálogo con una parte de la producción de María Bertely. Para ello, y en referencia a los espacios académicos que compartimos con María, retomamos algunos análisis y reflexiones nodales en torno a las líneas de investigación que hemos desarrollado desde hace varias décadas referente a escolarización indígena en contextos urbanos y de migración en México. Este campo de estudio cobra cada día mayor importancia ante la creciente migración de población indígena a las diversas urbes del territorio nacional. Entre sus múltiples causas y consecuencias, tanto estructurales como coyunturales, analizamos sus vínculos e implicaciones con el contexto escolarizado, principalmente en este texto referido a la educación básica, a la luz de las políticas públicas nacionales e internacionales.Bertely fue pionera en los estudios que abordaron la relación entre escuela y migración indígena en contextos urbanos. En el tejido de estos debates, las autoras desarrollamos una serie de investigaciones que visibilizan el derecho a la educación con reconocimiento cultural y lingüístico, y en particular de poblaciones indígenas en escuelas del sistema general del territorio nacional. El trabajo, más que reflejar un estado del conocimiento sobre el tema, documenta ciertos recorridos que refieren a transformaciones epistémicas y metodológicas ocurridas en la investigación antropológica educativa. Asimismo, busca contribuir a las políticas públicas en el campo de la educación y la diversidad e intercultural, enfoque que en la actualidad orienta a todo el sistema educativo en México.

Tomando a pesquisa em Educação como objeto de análise, tem-se debruçado sobre a preocupação com os elementos da pesquisa científica, dentre eles, o tema de pesquisa. Nesse sentido, elencam-se como problemática as temáticas referentes à pesquisa em Educação apresentadas aos Programas de Pós-Graduação em Educação, na região Nordeste. A partir do problema proposto, o objetivo é verificar os temas abordados em teses defendidas na área da Educação, no intuito de identificar a produção de conhecimento na área nos últimos anos. Metodologicamente, a empiria nesta pesquisa consiste nos resumos das teses defendidas nos Programas de Pós-Graduação em Educação nas universidades públicas da região Nordeste em 2020, 2021 e 2022. Trata-se de uma pesquisa exploratório- -bibliográfica e descritivo-sistemática em sua análise, que apresenta resultados que destacam a existência de um conjunto consistente de temas abordados e, ao mesmo tempo, a presença de tantos outros temas externos à área da Educação.

Este trabalho trata do estudo da estabilidade de um creme corporal com óleo de alecrim em comparação com o creme sem óleo essencial de alecrim. A pesquisa foi realizada no laboratório de farmacologia do Instituto Federal de Palmas/PR, Campus Palmas. O material vegetal fresco de alecrim coletado foi submetido a extração do Óleo Essencial por hidrodestilação com Clevenger, durante o período de duas horas a temperatura de ebulição. O óleo essencial de alecrim foi incorporado em um fluido hidratante à composição de 0,5%. Para acompanhamento do comportamento das estabilidades das emulsões seguiu-se as metodologias propostas pela Farmacopeia Brasileira. Foram realizados os testes de centrifugação, pH, ciclo de congelamento e descongelamento e a densidade. O rendimento do óleo foi de 0,1047%, inferior aos achados na literatura 0,30%, podendo-se atribuir este fato as diferentes edafoclimáticas as quais as plantas estão submetidas. No que se refere a estabilidade preliminar da loção testada, pode-se dizer que a adição do óleo essencial de alecrim não impactou negativamente na loção base, pois os parâmetros de densidade, pH e aspecto após congelamentos, descongelamentos e centrifugação, não demonstraram alterações relacionadas a degradação do produto. Um ponto positivo observado em relação a adição do óleo a loção foi que o pH do produto apresentou-se próximo ao pH cutâneo diferente da loção base utilizada.

Laiks
Authors: Vēgners Uldis
Published: June 2024

Uldis Vēgners’ paper “Time” is a take on two issues related to philosophy of time. In the first part of the paper, Vēgners addresses the problem of the true nature of time, but the second part of the paper is a discussion about the conditions of experience of time. / Laiks ir viena no universālākajām kategorijām mūsu domāšanā, tomēr atbildēt uz jautājumu, kā mēs varam definēt laiku, kāda ir laika daba, nav nemaz tik vienkārši. Ulda Vēgnera rakstā “Laiks” tiek piedāvāts ieskats mūsdienās aktuālās filosofu diskusijās par diviem ar laika izpratni saistītiem jautājumiem. Pirmkārt, tas ir jau minētais jautājums – kas ir laiks? Otrkārt, tas ir jautājums – kādi pieredzes nosacījumi ir nepieciešami, lai laika pieredze būtu iespējama? U. Vēgners šo jautājumu apskata, izšķirot trīs pamatpieejas jautājuma risinājumos – kinematogrāfisko, retencionālo un ekstensionālo modeli. 6.3. Filozofija, reliģija, ētika.

Ārprāts
Authors: Žabicka Anna
Published: June 2024

Anna Žabicka’s paper “Madness” highlights historically and culturally shaped explanations, understandings, and approaches to madness and addresses such questions as whether madness is biological or socially constructed, universal or culturally relative. / Anna Žabicka rakstā “Ārprāts” uzmanību pievērš normas un patoloģijas problemātikai. Ārprāta konceptualizācija ir saistīta ar konkrētu sociālu kontekstu, kurā pastāv priekšstati par to, kas ir garīgā veselība. Vienlaikus tā ir arī medicīniska problēma, tādēļ tiek aplūkota mūsdienu Rietumu psihiatrijas pieeja, kas tradicionāli ir balstīta uz biomedicīnisko modeli. Vēsturisks ieskats ārprāta diagnosticēšanā un ārstēšanā atklāj centienus marginalizēt ārprātīgos – izraidīt viņus no sabiedrības vai izolēt speciālās klīnikās. Nozīme ir arī starpkultūru pētījumiem, kas parāda, kā konkrētā kultūra veido jēdziena “ārprāts” saturu un ļauj nodarboties ar starpkultūru psihiatriju un psihiatrisko antropoloģiju. Tas ļauj runāt ne tikai par bioloģiskām un sociālām disfunkcijām, bet arī par kultūrspecifiskiem sindromiem. Turpinājumā aplūkots sociālais konstrukcionisms, sociālā marķēšana un antipsihiatrijas kustība. Nobeigumā tiek secināts, ka, nenoliedzot atsevišķu ārprāta simptomu bioloģisko izcelsmi, to nevar aplūkot kā naturālu fenomenu, bet gan vienīgi kā sociālu veidojumu, kurā ārprātīgie parādās kā intersubjektīvi aģenti, kas aktīvi piedalās ārprāta konceptualizēšanā. 6.3.

Islas. Un archipiélago semiótico
Authors:   Universidad de Cagliari (Italia), Sedda Franciscu
Published: June 2024

The essay explores the being-island through a cultural semiotic perspective. After accounting for the intimate tension between finiteness and infinitude, which constantly characterizes the island condition, through the analysis of various experiences and materials, the argument reveals the existence of four vectors of meaning, four fundamental relations: that between the island and the sea, between the island and the continent, of the island with other islands, of the island with itself. These vectors, on the one hand, help to grasp and clarify the historical and phenomenological richness of life of and on the islands. On the other hand, they offer models of spatiality and identity that transcend the mere insular dimension.
