Under the Veil of Tolerance: Critics on Tolerant City Index
Authors:   Center for Religious and Cross-Cultural Studies, UGM, Yogyakarta, Attaftazani Muhammad Ikhsan
Published: May 2024

Religious tolerance in Indonesia has become phenomenal in the last decades after Setara Institute was established alongside other NGOs such as Wahid Foundation. There is an annual index of tolerant and intolerant cities in Indonesia conducted by the Setara Institute. Other religious indexes are also mentioned, such as the index of Freedom of Religion and Belief (FORB) by Wahid Foundation and the Religious Harmony index by the Ministry of Religious Affairs. This index shows the interreligious relations within society and measures tolerance from the FORB index. To some extent, this index led to the competition of cities in Indonesia to be the most tolerant. This research examines the problem within the index from a philosophical perspective. Furthermore, the effect of the religious tolerance index on local government policies and everyday engagement in society will be addressed. This research uses a qualitative analysis method and collects data through library research. This research shows some problems in the index, such as binary opposition and generalized intolerant action with religious motives. In addition, the tolerance tends to move into pragmatic tolerance instead of mutual tolerance after the index emerges.
Fenomena Pasca-Kebenaran: Belajar dari Sejarah, Menyongsong Tahun Politik 2024

Published: May 2024

This writing aims to dissect several aspects of the Post-Truth phenomenon in general, including its definition, the reasons behind its emergence, its elements or characteristics, as well as its impacts. To make it easier to comprehend, real-life examples will be provided, both in the political and mass media spheres, which happened both internationally and within Indonesia. In this research, we use qualitative method through literature and internet review. Learning from history, the Post-Truth phenomenon is rampant during political campaigns leading up to elections. Therefore, as the year 2024 approaches, a significant political year in Indonesia, efforts need to be made to anticipate the negative impacts of Post-Truth. These negative consequences can foster distrust in society, provide opportunities for irresponsible individuals to take advantage, and potentially threaten the stability, security, and unity of the nation. To address this issue, all parties and authorities involved must collaborate and employ a multidimensional approach called the "Four-IS Solution," which includes efforts in philosophical, sociological, technological, and aesthetic education.
Stigmatisasi dan Diskriminasi Terhadap Odha di Maumere dalam Terang Teologi Pemerdekaan Mangunwijaya

Published: May 2024

This article aims to analyze the experiences of stigma and discrimination experienced by People Living with HIV-AIDS (PLWHA) in Maumere-Flores. The authors conducted qualitative research using in-depth interviews and participatory observation at the Flores Plus Support-Maumere Peer Support Group (KDS) from December 2022 to March 2023. Using the concept of Mangunwijaya’s theology of independence, this article analyzes the experiences of the suffering of PLHIV. According to Mangunwijaya, humans must be free from various forms of injustice that degrade their dignity. Two indicators for assessing the struggles of PLWHA are awareness of experiences of oppression and aspirations for self-determination. The results of this study indicate that situations of slavery as opposed to true freedom are still often experienced by PLHIV in Maumere. They are labeled as disgrace person, shunned by their families, or even thrown out of their homes. However, on the other hand, they are also aware of their suffering and try to find a way out of these various traumatic experiences.
Solidaritas Global Sebagai Cara Membangun Kebijakan Publik di Indonesia
Authors:   Program Magister Filsafat Keilahian-Universitas Sanata Dharma Yogyakarta, Indonesia, Nugraha Antonius Bagas Prasetya Adi
Published: May 2024

This paper is organized to look at the urgency of global solidarity as a means to build public policy in Indonesia. Indonesia, as a country with diverse challenges, including environmental issues, poverty, and social inequality, increasingly recognizes the need to work together with the international community to achieve sustainable development goals. Global solidarity reminds us that these challenges are not only local problems, but also global problems that require cooperation across borders. The global solidarity referred to here is one that leads to a Catholic moral ethic that seeks to prioritize justice and peace. Meanwhile, public policy itself requires strengthening in the field of human behavior. Through literature research on Hollenbach's thoughts, the question arises whether solidarity is important in living as a citizen? Public policy is not just making rules in such a way that they must be obeyed, obliged, and carried out by the community. Public policy is first and foremost about creating a sense of citizenship guided by humanity towards the common good.
Meritokrasi, Populisme Kanan, dan Revitalisasi Diskursus Publik: Perspektif Filosofis Michael Sandel
Authors:   Fakultas Filsafat Universitas Katolik Widya Mandira Kupang, NTT, Indonesia, Tan Petrus
Published: May 2024

This article aims to elaborate the phenomenon of right-wing populism based on the thought of Michael Sandel on the tyranny of meritocracy. Various previous literatures understand right-wing populism as an anti-pluralism and anti-globalization movement. However, these analyses fail to see that meritocracy has fueled the anger of working class and the losers as expressed in the populist movement. This study uses literature review and critical analysis methods. This study indicates that: 1) Meritocracy is a certain moral belief in individual success that justifies inequality as fair based on the basic principles of liberalism; 2) There are five key theses on meritocracy that trigger right-wing populism, namely: a person's fate is determined by individual success; everyone is responsible for their life; everyone can rise as long as they work hard; social inequality is a problem of person's income which is linear with their hard work; and education is a solution of social inequality; 3) Sandel’s criticism on meritocracy can be an alternative perspective to analyze populism in Indonesia. 4) The challenge of right-wing populism can be answered by revitalizing public discourse. This study concludes that meritocracy is a trigger for the right-wing populism in various democratic countries, including Indonesia.
Pandangan Jürgen Habermas Tentang Iman dan Akal Budi dan Implikasinya bagi Diskursus Seputar Peran Publik Agama di Indonesia
Authors:   Institut Filsafat dan Teknologi Kreatif, Ledalero-NTT, Indonesi, Madung Otto Gusti Ndegong
Published: May 2024

This essay describes the most important aspects of the relationship between religion and the state, especially in the case of Indonesia. It argues that, on the one hand, religion and belonging to one’s religion should be acknowledged as a fundamental human right, and on the other, religion should also be protected by the state. Unfortunately, most of the time the state seems to prioritise religion over the people. As a result, minority groups may experience marginalisation, violence, and discrimination. In this regard, I will show that Habermas' view of the relation between reason and faith offers a cogent framework for structuring Indonesia's normative interaction between politics and religion. This paper makes the case that the state's function in the Indonesian pluralistic society is to ensure religious freedom rather than to defend religion. Habermas holds that religion in has a substantial role in the public sphere even in a secular society. On the other hand, religions in a pluralistic society must also learn to reconcile disparities of their core ethical and metaphysical ideas. As a result, religions living in Indonesia may contribute to uphold democracy, human rights, equality, and freedom.
Gereja Memperjuangkan Keadilan dalam Kajian “Theory of Justice” John Rawls
Authors:   Universitas Sanata Dharma Yogyakarta, Indonesia, Mite Arkadius
Published: May 2024

This article talks about the political and ethical duties of the Church in fighting for justice and the contribution of Rawls' Thought to the Church's struggle. The issue of justice is the responsibility of all social institutions. The church as a social institution is involved in it. The presence of the Church in social society has raised questions about whether it is appropriate for the Church to be actively involved in fighting for justice. The Church's struggle in overcoming social problems is not due to social demands themselves but rather the Church's initiative to embrace them as brothers. The value that the Church strives for is justice. Justice as an integral part of the mission of the Kingdom of God. Justice is the main problem in national and state life. The priority of justice is poverty. Poverty is caused by structures that ignore human equality and human dignity. Human dignity is the Church's mission in fighting for justice through the values of the kingdom of God. These values of the Kingdom of God are actualized by the Church in its mission.
ВРАЧЕБНОЕ ПРАВОНАРУШЕНИЕ: ДЕФИНИЦИЯ БЕЗ СОДЕРЖАНИЯ
Authors: Тихомиров Алексей
Published: May 2024

Среди авторов изученных публикаций понимание некорректности существующих подходов к определению профессиональных врачебных преступлений есть – нет понимания, в чем состоят ориентиры корректности. Если «врачебная ошибка», «дефект оказания медицинской помощи», «ятрогения» – это номинация без дефиниции, то «ненадлежащее исполнение врачом своих профессиональных обязанностей» - это дефиниция без содержания. Проблема состоит не столько в институционализации дефиниции профессиональных врачебных правонарушений, сколько в наполнении такой дефиниции содержанием, соответствующим характеру фактических отношений врача и пациента. Решение этой проблемы – не в ужесточении предписаний и наказаний за «ненадлежащее исполнение врачом своих профессиональных обязанностей», а в раскрытии правового содержания профессионального врачебного правонарушения, не противоречащем фактическому содержанию врачебной профессии.

Asas Praesumptio Iustae Causa dalam Hukum Acara Peradilan Tata Usaha Negara
Authors: Efendi Aan , Sudarsono
Published: May 2024

Penelitian ini mengidentifikasi dua permasalahan dari diadopsinya asas praesumptio iustae causa dalam hukum acara peradilan tata usaha, pertama, justifikasi eksistensi asas tersebut, dan kedua, muatan putusan peradilan tata usaha negara yang tepat atas keputusan administrasi pemerintahan yang dianggap sah sampai pembatalannya. Untuk menjawab dua permasalahan tersebut digunakan tipe penelitian hukum doktrinal dengan pendekatan peraturan perundang-undangan dan pendekatan konseptual. Justifikasi asas praesumptio iustae causa berasal dari tesis keterpisahan dalam positivisme hukum yang berpandangan bahwa keabsahan norma hukum dan pembatalannya dependen pada hukum itu sendiri. Norma hukum hanya akan kehilangan keabsahannya jika ada norma hukum baru yang mencabut keabsahan norma hukum sebelumnya. Muatan putusan peradilan tata usaha negara yang tepat untuk merespon keputusan administrasi pemerintahan yang dianggap sah sampai pembatalannya adalah menyatakan keputusan administrasi pemerintahan dapat dibatalkan yang berarti keputusan dan akibat hukumnya berakhir sejak dinyatakan demikian dalam putusan peradilan tata usaha negara.

Thermal radiation and MHD effect on the double-diffusive convective flow of second-grade fluid over a stretching sheet
Authors: Chandan K. G. , Mallikarjun B. Patil
Published: May 2024

An investigation is conducted into how radiation affects the non-Newtonian second-grade fluid in double-diffusive convection over a stretching sheet. When fluid is flowing through a porous material, the Lorentz force and viscous dissipation are also taken into account. The flow equations are coupled partial differential equations that can be solved by MATLAB’s built-in bvp4c algorithm after being transformed into ODEs using appropriate similarity transformations. Utilizing graphs and tables, the impact of a flow parameter on a fluid is displayed. On velocity, temperature, and concentration profiles, the effects of the magnetic field, Eckert number, and Schmidt number have been visually represented. Calculate their inaccuracy by comparing the Nusselt number and Sherwood number values to those from earlier investigations.

Authors: BELSITO Chiara , FRANCIOSI Chiara , DI PASQUALE Valentina
Published: May 2024

his study explores the impact of augmented reality (AR) on worker performance in manufacturing contexts through an analysis of case studies extant in the literature. Two specific analyses were conducted to assess the impacts of AR technologies on worker performance in terms of objective and subjective metrics, and in terms of their age, experience with the task and experience with the AR device. Regarding objective metrics, the results showed that the task completion time was reduced for some AR devices (projectors, monitors, tablets, smartphones), whereas the use of the head-mounted display (HMD) increased task-completion time; moreover, the error rate was reduced with any AR device compared with traditional methods. Regarding subjective metrics, the analysis underlined that operator perceived a lower workload with the HMD or the monitor compared with traditional methods. The age of operators did not influence performance, while the operators’ experience allowed for the improvement of human performance.
The visualization of geophysical and geomorphologic data from the area of Weddell Sea by the generic mapping tools

The paper concerns GMT application for studies of the geophysical and geomorphological settings of the Weddell Sea. Its western part is occupied by the back-arc basin developed during geologic evolution of the Antarctic. The mapping presents geophysical settings reflecting tectonic formation of the region, glaciomarine sediment distribution and the bathymetry. The GlobSed grid highlighted the abnormally large thickness of sedimentary strata resulted from the long lasting sedimentation and great subsidence ratio. The sediment thickness indicated significant influx (>13,000m) in the southern segment. Values of 6,000–7,000 m along the peninsula indicate stability of the sediments influx. The northern end of the Filchner Trough shows increased sediment supply. The topography shows variability -7,160–4,763 m. The ridges in the northern segment and gravity anomalies (>75 mGal) show parallel lines stretching NW-SE (10°–45°W, 60°–67°S) which points at the effects of regional topography. The basin is dominated by the slightly negative gravity >-30 mGal. The geoid model shows a SW-NE trend with the lowest values <18 m in the south, the highest values >20m in the NE and along the Coats Land. The ripples in the north follow the geometry of the submarine ridges and channels proving correlation with topography and gravitational equipotential surface.

The deepening and exploration of the loess-palaeosol section at the foot of the Kopasz Hill at Bodrogkeresztúr have been carried out to expand the existing knowledge of the Carpathian foothill palaeoenvironmental factors and their impact. The study deals with particle size analysis, organic matter and carbonate content. For the presentation of age-depth models, the OSL dates of Bodrogkeresztúr (BKT) and the 14C dates of Bodrogkeresztúr, brickyard 1 were used-, and the diagrams of the Accumulation Rates (AR) derived from them. These were compared with Mass Accumulation Rate (MAR) calculations based on OSL and 14C data from BKT and 14C data from Bodrogkeresztúr, brickyard 1. It became evident that there is a significant difference between the two sections, which may be due to the upland position, the overlap, or the wind tunnel effect. Sedimentological studies revealed coarser grain composition, however, the nearly complete absence of coarser sand fraction is also noticeable in the case of BKT. Also, the entire section is characterized by increased carbonate content due to post-sedimentation processes, recarbonization and leaching. The AR and MAR results show the difference between the suitability of different chronometric methods, indicating that the top of both sections may have been redeposited or eroded.

The soil microbiome is exposed to technogenic influence during the operation of metal structures. There are quantitative and qualitative changes in the microbiota of the technogenic ecosystem. During the study of the technogenic soil ecosystem (ferrosphere), samples of which were taken in the field (Chernihiv, Ukraine: 51°29’58”N, 31°16’09”E), the presence of corrosively active microbial cenosis was established: sulfate-reducing, denitrifying, iron-reducing (using acetate as the only electron donor, and Fe (III) as the only electron acceptor) and ammonifying bacteria. The predominant representatives of corrosively active groups of bacteria were isolated. They were identified as Bacillus simplex, Streptomyces gardneri, Streptomyces canus (ammonifying bacteria), Fictibacillus sp. (ammonifying bacteria with iron-reducing ability), Anaerotignum (Clostridium) propionicum (organic acid-producing bacteria), Desulfovibrio oryzae (sulfate-reducing bacteria) based on some microbiological, physiological and biochemical, genetic features. Strains of heterotrophic and hemolitotrophic bacteria (individual representatives and their associations) isolated from the technogenic ecosystem can be used in both industrial and technological spheres. The interaction of isolated bacteria in the process of microbial induced corrosion is a prospect for further research.

Plastics are materials with many properties that make them extremely popular in everyday life and various industries. Studies show that plastic debris is global pollution and widespread in virtually all ecosystems. This study aimed to assess the coastal sediments of Ełckie Lake in terms of the presence of microplastics. Samples of sediments (n = 37) from the coastal zone of Ełckie Lake were drawn from different areas, including urban, rural, and tourist locations, and beaches. After the coastal sediment samples taking, they were subjected to density separation, filtration, and visual evaluation using the Olympus BX63 fluorescent microscope. Particles were classified according to the category of visible characteristics of microplastics including size, shape and colour. The results of the study showed the presence of microplastics in 84% of the examined coastal sediment samples of Ełckie Lake. Fibres, flakes, granules, and foils (films) had found in 58%, 45%, 32%, and 13% of the samples that contained microplastic, respectively. The majority of the detected microplastic was 0.5–1 mm in size and black was the dominant colour. Spatial variability was perceived in microplastic concentrations, giving premises to the assumption of dependence between local human activity and the content of particles.

In spite of modern trends in the development of the eastern Polesye flora, the relict have been preserved in the aquatic ecotopes of Europe, including eastern Polesye. The paper highlights the peculiarities of the distribution in the region of three aquatic Tertiary relics preserved by the Bern Convention. According to the results of a field research, the degree of a modern rarity of the aquatic relict species in eastern Polesye was established, in particular, a very rare species ( Aldrovanda vesiculosa), a moderately rare species ( Trapa natans) and a relatively rare species ( Salvinia natans). The current distribution of these relict species in the region has been positively affected by the increase in the values of maximum temperatures and isotherms of the summer months. A negative impact is made by the abrupt changes in the hydrological regime and the growth of anthropogenic eutrophication of reservoirs. Aldrovanda vesiculosa eliminates with minor changes in living conditions; Salvinia natans is the most tolerant to anthropogenic factors, but shows annual fluctuations in numbers; Trapa natans is stable distributed and has a tendency to expanding of its populations. The relics are the dominants of the Salvinio–Spirodeletum (polyrrhizae), Lemno–Utricularietum vulgaris, Spirodelo– Aldrovandetum vesiculosae, Trapetum natantis and Trapо–Nymphoidetum (peltatae) communities.

The research aimed to make an inventory of the vascular flora of 11 parks and gardens of the Pomeranian Cistercian Trail, with particular emphasis on taxa attached to old deciduous forests. A total of 62 species were registered, recognised as indicators of old deciduous forests in Poland. The presence of species of this group was confirmed in all of the analysed objects, but their number varied from 7 to 50. The group of ancient woodland species includes forest species for which the light indicator values are lower than or equal to 4 (plants of shadowy places, with a relative light intensity). The group of indicator species also includes forest geophytes and forest myrmecochores, autochores and barochores, as well as woodland species that can tolerate stress, under the classification of ecological strategy types S, S/CSR, S/SC and S/SR.

Grain size distribution is one of the paleoenvironmental proxies that provide insight statistical distribution of size fractions within the sediments. Multivariate statistics have been used to investigate the depositional process from the grain size distribution. Still, the direct application of the standard multivariate methods is not straightforward and can yield misleading interpretations due to the compositional nature of the raw grain size data. This paper is a methodological framework for grain size data characterization through the centered log ratio transformation and euclidean data, coupled with principal component analysis, cluster analysis, and linear discriminant analysis to examine Quaternary sediments from Tövises bed in the southeast Great Hungarian Plain. These approaches provide statistically significant and sedimentologically interpretable results for both datasets. However, the details by which they supplemented the conceptual model were significantly different, and this discrepancy resulted in a different temporal model of the depositional history.

Carbonate rocks are among the sedimentary systems which preserve information on the formation and diagenetic history expressed in its composition (distribution of its major rock-forming components (RFC). For estimating RFC proportions at the micro-scale, a simple counting of visible RFCs in thin sections using overlaid grids is a long-used, well-established technique. However, computer tomography (CT) analysis provides us with quantitative data in 3D at both the scale of the entire sample and a resolution defined by dimensions of the voxels at the micro-scale. The quantitative data expressed in Hounsfield units (HU) correlates with the density of RFCs. In this work statistical properties of CT-based data for selected freshwater carbonate samples from the Danube-Tisza Interfluve have been assessed using histograms and boxplots. Univariate statistical parameters characterize each sample. The maximum-likelihood method of mixture analysis has been adapted to recover and estimate the parameters of these subpopulations. Subpopulations have been defined in the form of overlapping intervals using statistical parameters gained (mean±2STD). Five major components have been defined: empty and partially or entirely filled pores by calcite, limestone micrite, dolomite micrite matrix and limonite saturated matrix.
Extracellular vesicles in cattle infected with bovine leukaemia virus: isolation and molecular analysis
Authors: Szczotka Maria , Wasiak Magdalena , Kuźmak Jacek
Published: May 2024

Introduction

Exosomes are nanosized lipid bilayer membranous microvesicles, extracellularly released from a variety of mammalian cells. They mediate intercellular signalling by transporting several types of RNA, lipids and proteins and participate in the intercellular exchange of DNA, RNA, micro RNA, proteins and other components. These microvesicles are present in all body fluids in physiological and pathological conditions and reflect the state of the host organism. The aim of the study was the isolation and molecular determination of exosomes in blood and supernatant fluids of bovine dendritic cell cultures infected with bovine leukaemia virus (BLV).

Material and Methods

Exosomes were isolated by ultracentrifugation from the blood sera, plasma and supernatant of bovine BLV-infected and uninfected control dendritic cell cultures and their presence was confirmed with scanning electron and transmission electron microscopy. Western blot analysis of the structural BLV glycoprotein 51 (Env) and protein 24 (Gag) and of the tetraspanin exosomal markers CD9, CD63 and flotillin-1 was undertaken in BLV+ and control BLV− cattle.

Results

In exosomes of leukaemic cattle both BLV proteins and exosomal markers were detected. In healthy control animals only exosomal markers were determined.

Conclusion

Proteins of BLV were released with exosomes and could be transferred into recipient cells as an alternative propagation route not requiring virus infection.
Shear strengthening of deficient RC deep beams using NSM FRP system: Experimental and numerical investigation
Authors: Abadel Aref
Published: May 2024

It is essential to retrofit deep beams with shear inadequacies because these beams, although they have the same shear and flexural reinforcements as ordinary beams, are more susceptible to shear failure. Hence, it is of great significance to overcome the shear weaknesses in deep beams. This research paper aims to experimentally examine the effectiveness of near-surface mounted (NSM) carbon fiber reinforced polymer (CFRP) for retrofitting reinforced concrete (RC) deep beams subjected to shear forces. The study involved three different types of specimens. The first specimen was constructed with concrete throughout its span and included shear stirrups. The second specimen was divided into two halves, with one half lacking shear reinforcements and the other half having them. The third specimen had steel web reinforcement in one half of the span, while the other half was strengthened using NSM CFRP U-wrap strips and externally bonded horizontal CFRP strips. The proposed strengthening method significantly increased the shear strength of the deep beams, surpassing that provided by steel web reinforcement alone. Furthermore, the NSM CFRP strengthened specimen exhibited a change in failure mode from shear to flexural failure. In comparison to the control beam without stirrups, the beams strengthened with NSM CFRP U-wrap strips demonstrated an impressive 82% improvement in shear strength, while the beam with shear reinforcement showed a 23 % enhancement in load capacity. The proposed strengthened scheme is capable of enhancing the structural performance and load-carrying capacity effectively. A finite element model was generated utilizing ABAQUS software to simulate the behavior of the tested deep beams and verified against the experimental outcomes. The numerical models successfully predicted the behavior of the RC deep beams strengthened with NSM CFRP when compared to the experimental data.
Revisiting the Birthday Number Effect, Subjective Preferences, and Self-Esteem in College Students
Authors: Nutt Courtney G. , DiMassimo Anna N. , Hale Ralph G.
Published: May 2024

People tend to prefer details related to themselves. For example, people often like numbers associated with their birth date more than other numbers. This is known as the birthday number effect (Pelham et al., 2002). Discovery of this effect stemmed from the name-letter effect, a similar phenomenon in which individuals are likely to prefer letters in their name over other letters (Nuttin, 1985). The heightened fondness for details connected to oneself has been shown to influence decisions including where one lives and with whom one falls in love (Pelham et al., 2005). The present study attempted to replicate the birthday number effect. A significant preference for birthday numbers was found, F(1, 97) = 17.85, p < .001, ηp2 = .16. Previous research has suggested that this effect relates to self-esteem, but this association had not yet been tested. No correlation between self-esteem and birthday-related numbers was found in the present study, r(99) = -.02, p = .88. However, the study did find that women had significantly lower self-esteem than men, t(99) = -3.62, p < .001, d = -0.78. The knowledge gained from this study provides a deeper insight into implicit feelings regarding the components of self-identity and how they relate to self-esteem in a college student population.
