Effect of Sustainable Supply Chain and Management Practices on Supply Chain Performance: The Mediating Roles of Ethical Dilemmas and Leadership Quality
Authors: Uddin Muhammed Sameer , Mohamed Omaima Eltahir Babikir , Ebert John
Published: December 2024

The objective of this study is to examine the influence of Sustainable Supply Chain (SSC) and Supply Chain Management Practices (SCMP) on Supply Chain Performance (SCP). It seeks to explain how organizations might utilize SSC and SCMP to improve performance by promoting ethical practices and good leadership. An empirical analysis was performed utilizing data gathered from 350 respondents from enterprises across several industries in Bangladesh through a quota sampling strategy. We used Partial Least Squares Structural Equation Modeling (PLS-SEM) to examine the direct and indirect effects. Ethical Dilemma (ETD) and Leadership (LED) quality were used as mediating variables. The results indicate that SSC and SCMP have a beneficial effect on SCP, with LED quality as a significant mediator. However, less directly impactful, ETD creates an essential framework for ethical practices inside the supply chain. The Importance-Performance Map highlights LED quality and SCMP as critical elements to improving SCP, suggesting that firms must prioritize these areas for optimal performance. The study's weaknesses include its cross-sectional methodology and concentration on a small geographic area, which may impact generalization. Future research may investigate SSC's long-term effects on SCP and future technologies' influence on ethical decision-making in global supply chains. This work enhances SSC literature by highlighting the significance of LED quality and ETDs as mediators in the link between SSC, SCMP and SCP.

Authors: Etxaburu Nerea , Herrero Marta , Momeñe Janire , Estévez Ana
Published: December 2024

Although emotional dependence has been considered to be directed towards friends, only assessment instruments for measuring emotional dependence towards a partner have been found. The study aims to create and validate the “Questionnaire of Emotional Dependence on Friends (CDEA)”. Three studies were conducted to develop and validate the questionnaire. The preliminary version was administered to a sample of 278 adolescents, together with measures of emotional dependence on partners. The final version was administered to a sample of 675 adolescents, together with measures of attachment, stress, anxiety and depression. The CDEA scale was finally composed of 12 items grouped into two correlated dimensions: Exclusivity and Excessive Focus. It has shown adequate convergence with other emotional dependence instruments and related constructs. The CDEA is a brief self-report, valid and easy-to-complete assessment instrument that allows us to evaluate emotional dependence on friends in an adolescent population.

The mediation of self-esteem and hostility in the relationship between social support and dating violence
Authors: Jaureguizar Joana , Dosil-Santamaría María
Published: December 2024

The aim of this study was to investigate whether self-esteem and hostility mediated the relationship between social support and online and offline dating violence (DV) in 479 university students. All types of social support (family, friends and relevant people) were positively related to self-esteem and negatively related to almost all types of violence. In addition, self-esteem correlated inversely with levels of hostility, and the latter was positively related to online and offline perpetrated DV. Path analyses showed that lower levels of self-esteem and higher levels of hostility mediated the relationship between family social support and online and offline DV. However, social support from friends and significant others only had a direct effect on online DV. Despite the limitations of the cross-sectional design, social support, self-esteem and hostility appear to be important aspects in the prevention and treatment of DV.
Self-concealment, depressive symptoms, and seeking professional help: Evidence of an invariance model
Authors: Salinas-Oñate Natalia , Segú Flores María José , Salazar-Fernández Camila , Baeza-Rivera María José , Olivera Mauro
Published: December 2024

This study examines the relationship structure between self-concealment, depressive symptoms, and professional help-seeking, and evaluates its invariance by gender in a sample of 500 Chilean university students. Multi-group structural equation models were used to examine invariance and the relationship structure between variables. The hypothesized model showed a good fit to the data, χ2(132)= 189.793, p< .050, CFI= .993, TLI= .991, RMSEA= .030 [.020, .039], SRMR= .052, and achieved strict (residual) invariance. For both groups, self-concealment is directly and significantly related to depressive symptoms. In female there is a significant inverse relationship between self-concealment and professional help-seeking, while in male self-concealment has an indirect relationship with professional help-seeking, mediated by depressive symptoms. These results underscore the hindering role of self-concealment and the importance of considering gender differences in understanding professional help-seeking for mental health.

Published: December 2024

El presente estudio tuvo como objetivo establecer el rol mediador del capital psicológico en la relación entre el estrés académico y las conductas de salud de los estudiantes universitarios peruanos durante la pandemia del covid-19. Una muestra no probabilística de 708 estudiantes (548 mujeres y 160 hombres), de entre 18 y 61 años (M= 22,1; DT= 6,0), respondieron online al “Inventario SIStémico COgnoscitivista para el estudio del estrés académico - segunda versión de 21 ítems”, el “Cuestionario de capital psicológico” y el “Cuestionario de estilos de vida de jóvenes universitarios”. Los resultados del estudio confirman que el modelo se ajusta adecuadamente a los datos, destacando tanto el efecto directo del estrés académico sobre las conductas de salud y el capital psicológico, como el efecto del capital psicológico sobre las conductas de salud. Es evidente que el capital psicológico actúa como variable parcialmente mediadora en la relación entre el estrés académico y las conductas de salud. Estos resultados ponen de relieve el papel del capital psicológico como factor mitigador del estrés y potenciador de las conductas saludables en los estudiantes universitarios.
Yiddish Zionist Calendars in the Russian Empire, 1887-1914
Authors: Cohen Natan
Published: December 2024

This article examines a little-studied medium, namely the calendar, in its broadest
sense, which resembles the model of the almanac. The focus is on calendars in
Yiddish, the everyday language of most Eastern European Jews. The number of
these calendars grew steadily in the late 19th century and early 20th century, including
those used by their editors to disseminate the idea of Hibbat Zion (Love of Zion),
and later the Zionist idea. These calendars were published in the three main centers
of Zionist activity before World War I: Odessa, Pinsk, and Vilna. Some of the
calendars were local in character, while others were regional. The editors, who were
recognized figures in their communities, selected a variety of content to present
to their readers, which were primarily intended to instill national awareness, and
in turn a sense of connection to the idea of a return to Zion and interest in the new
Jewish settlement in the Land of Israel.
NILAI TINDIH SUKU SASAK SEBAGAI PEDOMAN HIDUP UNTUK MENINGKATKAN EMPATI DAN SIKAP HORMAT SISWA
Authors: NURAENI NURAENI , SUHARDI MUHAMAD
Published: December 2024

Moral values, particularly respect, are fundamental principles that grow and develop from the value of empathy. Empathy, in this context, is a moral value that can positively contribute to an individual's moral development. Empathy and respect are among the foundational moral values that influence other virtues such as responsibility, friendship, peacefulness, honesty, and tolerance, which are integral to humanitarian values. One of the local wisdom values believed to enhance individual understanding and actions is the tindih value of the Sasak tribe. The tindih value refers to a core principle emphasizing commitment and consistency to truth and nobility, which is rooted in faith. The fundamental tindih value is supported by a protective value system that safeguards individuals and society from humanitarian degradation, namely maliq and merang. Maliq signifies the prohibition of engaging in inappropriate and unbeneficial actions. Meanwhile, merang embodies social solidarity, characterized by empathy and concern for others.
ABSTRAKNilai moral berupa sikap hormat atau respect merupakan nilai dasar yang tumbuh dan berkembang dari nilai empati. Nilai empati dalam hal ini merupakan nilai moralitas yang dapat berkontribusi positif terhadap perkembangan moral individu. Empati dan sikap hormat  merupakan salah satu nilai (kualitas dari perbuatan) yang merupakan nilai moral paling dasar bagi nilai-nilai lainnya yang juga dapat berpengaruh terhadap nilai tanggung jawab, persahabatan, cinta damai, rasa hormat, kejujuran dan toleransi nilai-nilai kemanusiaan. Adapun salah satu nilai kearifan lokal yang dianggap dapat meningkatkan pemahaman dan perbuatan individu adalah nilai tindih suku Sasak. Adapun yang dimaksud nilai tindih adalah nilai dasar yang menekankan pada komitmen dan konsistensi pada kebenaran dan keluhuran yang bersumber dari keimanan. Adapun nilai dasar tindih didindingi oleh sistem nilai penyangga untuk membentengi diri dan masyarakat dari degradasi kemanusiaan yaitu maliq dan merang. Lebih lanjut maliq berarti pantangan melakukan hal yang tidak pantas dan tidak bermanfaat. Sedangkan merang mengandung nilai solidaritas sosial yaitu sikap tenggang rasa, dan perduli terhadap sesama atau mampu berempati.
ANÁLISE DA REGULAMENTAÇÃO DO TRABALHO DA JUVENTUDE GAMER A PARTIR DO ASPECTO DE VIOLAÇÕES DE DIREITOS
Authors: Pereira Thales Antonio Cardoso
Published: December 2024

O presente trabalho analisa a situação dos jovens que atuam como jogadores profissionais de jogos eletrônicos, com foco nas condições de trabalho, nos direitos trabalhistas violados e nas políticas públicas existentes no Brasil. A pesquisa destaca a importância de reconhecer os eSports como modalidade esportiva legítima, dado seu caráter cognitivo e estratégico, similar a práticas como o xadrez. A evolução histórica do conceito de esporte, moldado por contextos culturais, corrobora essa inclusão, especialmente em um mundo cada vez mais tecnológico. Além disso, a ausência de políticas públicas agrava a vulnerabilidade dos jovens, limitando a diversidade e a inclusão no cenário. Pais, muitas vezes inseguros quanto à viabilidade dos eSports como carreira, contribuem para um ambiente de exploração financeira. Em resumo, o projeto visa contribuir para o debate sobre as condições de trabalho precárias enfrentadas pelos jovens que trabalham com jogos eletrônicos no Brasil e para o desenvolvimento de políticas públicas que garantam seus direitos trabalhistas e sociais.

O Transtorno do Espectro Autista (TEA) caracteriza-se por déficits no desenvolvimento social, comunicação e padrões comportamentais repetitivos. Este estudo objetiva explorar os impactos de intervenções terapêuticas multimodais no desenvolvimento cognitivo e social de indivíduos com TEA. Realizou-se uma revisão integrativa, abrangendo artigos publicados entre 2015 e 2023, consultados em bases de dados como PubMed, Scopus e SciELO. Os resultados evidenciaram que estratégias combinadas, como terapia comportamental, intervenção sensorial, uso de tecnologia assistiva e programas educacionais personalizados, promovem avanços significativos na interação social, habilidades de comunicação e funções executivas. Além disso, intervenções precoces mostraram-se particularmente eficazes, destacando a plasticidade cerebral em períodos críticos do desenvolvimento. Contudo, os desafios incluem a necessidade de adaptações individuais e a limitação de estudos de longo prazo. Conclui-se que intervenções multimodais, quando aplicadas de forma integrada e personalizada, representam uma abordagem promissora para maximizar o potencial cognitivo e social de indivíduos com TEA.

Published: December 2024

Esse artigo buscou identificar a necessidade de capacitação do enfermeiro, na atuação junto ao paciente em cuidados paliativos com ferida neoplásica. Metodologia: trata-se de uma revisão bibliográfica de natureza descritiva. Resultados e discussão: Os cuidados paliativos se tornam humanizados ao buscar ir além do tratamento centrado unicamente na doença ou na possibilidade de morte. Percebe-se que, diante da terminalidade humana, os cuidados paliativos são essenciais, pois visam proporcionar uma melhor condição de saúde na fase final da vida, aliviando sofrimento, ansiedade e depressão diante da morte. Conclusão: A nova definição de Cuidados Paliativos valoriza a qualidade de vida em vez de focar na terminalidade, ressaltando a importância de uma abordagem holística e ampla para esses pacientes, promovendo a prevenção e o alívio do sofrimento. A pouca e desatualizada literatura disponível sobre a temática representa uma limitação para o estudo, o que reforça sua importância para a prática da enfermagem.
Uma análise semiótica do canibalismo Tupinambá
Authors: Arcanjo-Filho Miguel , Monteiro Fóes Maira , Nascimento de Araújo Neto Waldmir
Published: December 2024

O ensaio oferece uma reconstrução histórica do canibalismo como prática entre os Tupinambá, ao considerar o impacto desses rituais no imaginário europeu. A prática tem sido profundamente estudada e mais bem entendida, não sendo mais associada meramente à alimentação, mas principalmente a rituais ligados à guerra e à vingança. O ritual de sacrifício do inimigo era o ponto culminante de uma complexa rede de procedimentos. A antropofagia era uma das maneiras de garantir a continuação do ciclo da vida, reincorporando o inimigo à comunidade e buscando restaurar o equilíbrio após conflitos. Usa-se a semiótica de Peirce para analisar tais aspectos da prática ritual Tupinambá e destacar sua dimensão temporal e ligação com a vingança. Esta análise semiótica demonstra como a interação de signos redefine a maneira como os eventos são interpretados, destacando a importância do "fluxo perceptivo" como categoria teórica na compreensão da cosmogonia Tupinambá.
Variasi Ortografi Khusus Pegon Dalam Teks Syi'ir Tandha Qiyamat
Authors: Irakusuma Ratna Nur Fatimah , H Hendrokumoro
Published: December 2024

This study aims to identify Pegon specific orthographic variations (Pegon special script). The special Pegon script referred to in this study is a script that represents Javanese sounds that are not possessed by Arabic sounds. The consonant sounds mentioned above are /c/, /g/, /p/, /ṭ/, /ḍ/, /ŋ/, and /ñ/. Each of the phonemes mentioned above has at least two variations of orthographic shapes. These variations are in the form of the position of the graphem in the word, the presence or absence of dots, and the number of dots in the script in question. The adoption and adaptation of Hijaiah graphemes into Pegon's special graphemes tends to be based on the proximity of the original grapheme articulation point into the fabricated graphem or the similarity of the resulting sound. Grapheme modifications carried out in the adaptation process are in the form of modifying the number of points in the Hijaiah script that have dots and adding a single point to the Hijaiah script that does not have points. Combining philological methods with linguistic orthographic theory, this study gives a new color to the study of language descriptions, especially Javanese.

This article examines the existence of Tawan Karang Rights as one of the traditional legal practices in the archipelago which was maintained by the coastal communities of the Dutch East Indies until the end of the 19th century. The focus of this research is to understand how Tawan Karang Rights as a form of customary law interact, conflict and negotiate with the international shipping legal framework introduced by the Dutch colonial era. This research uses legal research methods by looking at the legal products of Tawan Karang in the Kingdom of Bali and the Kingdom of Teunom, in Aceh and comparing them with conventional shipping law at that time. This article shows that the interaction between Tawan Karang Rights and international shipping law in the Dutch East Indies was a reflection of the broader conflict between customary law and colonial law. This practice not only reflects the socio-economic dynamics of coastal communities, but also highlights how customary law attempts to negotiate its existence in the face of modern legal pressures brought about by colonialism.
 
Artikel ini mengkaji keberadaan Hak Tawan Karang sebagai salah satu praktik hukum tradisional di Nusantara yang dipertahankan oleh masyarakat pesisir Hindia Belanda hingga akhir abad ke-19. Fokus penelitian ini adalah memahami bagaimana Hak Tawan Karang sebagai bentuk hukum adat berinteraksi, berkonflik, dan bernegosiasi dengan kerangka hukum pelayaran internasional yang diperkenalkan oleh kolonial Belanda. Penelitian ini menggunakan metode penelitian hukum dengan melihat produk hukum Tawan karang di Kerajaan Bali dan Kerajaan Teunom, di Aceh dan mengkomparasikannya dengan hukum pelayaran konvensional kala itu.  Artikel ini menunjukkan bahwa interaksi antara Hak Tawan Karang dan hukum pelayaran internasional di Hindia Belanda merupakan cerminan dari konflik yang lebih luas antara hukum adat dan hukum kolonial. Praktik ini tidak hanya mencerminkan dinamika sosial-ekonomi masyarakat pesisir, tetapi juga menyoroti bagaimana hukum adat berupaya menegosiasikan keberadaannya dalam menghadapi tekanan hukum modern yang dibawa oleh kolonialisme.
Dinamika Kelompok, Daya Tarik Interpersonal Dan Perkembangannya

Published: December 2024

Humans are the most perfect living creatures compared to other creatures. The goal that humans want to achieve in their lives is a better life. Therefore, humans need to be formed or directed through education or knowledge which influences knowledge about themselves and their world, social life, and through religion. The formation of better humans is not in the sense of morals or whether humans are good or bad, but rather the formation of humans into living and cultured creatures from the perspective of cultural philosophy, namely wiser and more critical lives. As humans living in an environment, humans are never free from the need for other people. Because there are limitations within himself that must be covered by the presence of other people. However, sometimes other people's needs are more due to similar goals and motives to be achieved. This causes a person to try to build a bond to solve each problem by means of a so-called association. Each individual in the group will develop their abilities to achieve the goal. So the group plays a major role in fulfilling the goals of its members. This is where group dynamics, theories of group formation, group characteristics, types of groups, the basics of interpersonal attraction, and stages of group development will be discussed in full.
Manusia merupakan mahluk hidup yang paling sempurna apabila dibandingkan dengan makhluk lainnya. Tujuan yang ingin dicapai oleh manusia dalam kehidupannya adalah kehidupan yang lebih baik. Untuk itu, manusia perlu dibentuk atau diarahkan melalui pendidikan atau ilmu yang mempengaruhi pengetahuan tentang diri dan dunianya, kehidupan sosial, dan melalui agama. Pembentukan manusia yang lebih baik bukan dalam arti moral atau baik buruknya manusia, melainkan pembentukan manusia sebagai makhluk yang hidup dan berbudaya dalam perspektif filsafat budaya, yaitu hidup yang lebih bijaksana dan lebih kritis. Sebagai insan yang hidup dalam suatu lingkungan, manusia tidak pernah terlepas dari kebutuhan akan orang lain. Karena adanya keterbatasan dalam dirinya yang harus ditutupi dengan kehadiran orang lain. Namun, terkadang kebutuhan akan orang lain lebih disebabkan karena adanya persamaan tujuan maupun motif yang ingin dicapai. Hal tersebut menyebabkan seseorang berupaya membangun suatu ikatan untuk menyelesaikan setiap persoalannya dengan cara perkumpulan yang disebut kelompok. Setiap individu di dalam kelompok akan mengembangkan kemampuan yang dimiliki untuk mencapai tujuan. Sehingga kelompok berperan besar dalam memenuhi pancapaian tujuan para anggotanya. Disinilah akan dibahas lengkap mengenai dinamika kelompok, teori-teori pembentukan kelompok, ciri-ciri kelompok, jenis-jenis kelompok, dasar-dasar daya tarik interpersonal, dan tahap-tahap perkembangan kelompok.
Dual-frequency radar observations of snowmelt processes on Antarctic perennial sea ice by CFOSCAT and ASCAT
Authors: Xu Rui , Zhao Chaofang , Arndt Stefanie , Haas Christian
Published: December 2024

Abstract. Since 2017, Antarctic sea ice coverage has shown significant reductions, and therefore observations of its surface melting behavior are of utmost importance. Here we study the capability of the Ku-band Chinese-French Oceanography Satellite Scatterometer (CFOSCAT) launched in 2018 to detect surface melting and compare it with more established observations of the C-band Advanced Scatterometer (ASCAT) in orbit since 2007. Both CFOSCAT and ASCAT observations show increases in radar backscatter of more than 2 dB over perennial ice once the ice surface warms and destructive snow metamorphism commences, defined as pre-melt onset (PMO). Backscatter increases by more than 3 dB once prominent thaw–freeze cycles commence, defined as snowmelt onset (SMO). Scatterometer data are compared with drifting buoy and ERA5 reanalysis air temperature data to support the interpretation of melt-related snow processes. Between 2019 and 2022, the average CFOSCAT pre-melt and snowmelt onset dates for 12 perennial ice study regions are 9 November (±23 d) and 1 December (±22 d), earlier than those of ASCAT on 21 November (±22 d) and 11 December (±25 d), respectively. Sensitivity tests show that results depend slightly on chosen backscatter thresholds but little on sea ice concentration. The derived SMOs are in good agreement with previous studies, but the SMO difference between dual-frequency radar observations is smaller than that reported by previous studies due to the sensor differences and different spatiotemporal resolutions. SMO differences between dual-frequency radar observations were also found to be potentially related to regional differences in snow metamorphism. With regard to the long-term changes in SMO, there are strong interannual and regional variabilities in SMO changes, and no consistent changes could be detected among different sub-regions with the beginning of Antarctic sea ice decline after 2015. Dual-frequency CFOSCAT and ASCAT observations hold strong promise for a better understanding of snowmelt processes on Antarctic sea ice, and it is necessary to extend the observation of Antarctic snowmelt based on dual-frequency scatterometers.

В работе по данным спутников серии NOAA POES изучаются высыпания релятивистских (>800 кэВ) электронов (ВРЭ) наблюдаемые в верхней ионосфере Земли, связанные с ослаблением напряженности магнитного поля в районе Южно-Атлантической (Бразильской) аномалии. ВРЭ регистрировались во время геомагнитной бури 10 – 17 октября 2017 г., которая сопровождалась многочисленными суббурями. Показано, что несмотря на меньшую максимальную интенсивность (потоки 103 - 104 (см2 с ср)-1) по сравнению с другими высыпаниями (связанными с ЭМИЦ и свистовыми волнами, а также с питч-угловой диффузией в области большой кривизны силовых линий геомагнитного поля), их вклад в опустошение радиационного пояса может быть существенным. Отчасти это обусловлено их большей продолжительностью (20-220 с). Проведен анализ влияния суббуревой активности на частоту появления таких ВРЭ.
Extended surfaces with increased current density and magnetic field configurations in the vicinity of current density maxima: MHD simulation above the active region
Authors: Podgorny А.I. , Podgorny I.M.
Published: December 2024

The fast energy release in the solar corona is explained by solar flare mechanism of S.I. Syrovatsky, according to which the energy for flare is accumulated in the magnetic field of the current sheet. The observed manifestations of the flare are explained by the electrodynamic model of the solar flare proposed by I. M. Podgorny. To study the mechanism of a solar flare it is necessary to carry out MHD simulation above the active region, which is initiated several days before the flare. Here is the first attempt is make to solve the problem of coincidence of solar flare position obtained by MHD simulation with observed one using extended surface of magnetic lines, passing through the chain of current density maxima, which is found as result of MHD simulation.
Soil dynamic features of Atatürk University Campus (Erzurum), eastern Türkiye, by microtremor method
Authors: Saraç Beytullah , Özer Çağlar
Published: December 2024

Erzurum province is located close to two important faults, namely the North Anatolian Fault Zone and the East Anatolian Fault Zone. Additionally, numerous local faults such as the Aşkale, Başköy-Kandilli, Erzurum-Dumlu, Palandöken, and Horasan-Narman Fault Zones could potentially trigger devastating earthquakes for Erzurum province. All these seismic hazard sources require a well-understanding of the soil dynamic properties in Erzurum province. The single-station microtremor method were carried out at 45 points to determine the Atatürk University Central Campus-Erzurum soil dynamic parameters with this motivation. Seismic vulnerability index and seismic bedrock depth values were calculated with the help of empirical relations using the soil dominant frequency and soil amplification factor values calculated from the horizontal/vertical spectral ratio method. The south-eastern region of the study area exhibits characteristics such as low soil dominant frequency values, high soil amplification factor values, elevated Kg values, and considerable engineering bedrock depth. This area is particularly vulnerable to potential earthquake damage due to its high sediment thickness and susceptibility to site effects. Notably, points three and four also demonstrate low soil dominant frequency values, coinciding with the locations of hospitals and administrative units. Therefore, it is imperative to intensify site effect investigations, especially using active sources of geophysical methods in these specific areas

Published: December 2024

Hydraulic conductivity (k) is a crucial parameter in hydrogeology and engineering geology, describing the rate at which water filters through porous media, i.e., soil. It can be determined directly through tests on soil samples in situ, or it can be calculated from other soil parameters using various equations and models. This study aims to compare the results of six machine learning (ML) models with those of four empirical formulas and to identify the soil parameters required for the optimal ML performance. A dataset consisting of 282 unique entries of Lithuanian soils was compiled from laboratory testing reports. Twelve features, including grain sizes and particle diameters, were used to create 4095 combinations of inputs for each ML algorithm. Prediction results were evaluated using the determination coefficient (R²) and the mean absolute error (MAE). The ML models provided more accurate predictions (R² 0.36–0.46, MAE 2.31–2.81 m/d) compared to the empirical formulas (R² 0.10–0.33, MAE 3.05–6.54 m/d). However, some ML models showed signs of overfitting. The study also revealed that each ML algorithm performs best with a customized combination of input parameters, ranging from 4 to 8, whereas the empirical formulas used in this study utilize only 1–2 parameters.
Der Einsatz von Placebos in der Medizin aus juristischer Sicht
Authors: Steiner Maria-Kristina
Published: December 2024

Die Wirkung von Placebos – z.B. gegen Schmerzen – im Körper ist eine tatsächliche. Es steht fest, dass assoziierte Umstandseffekte mittels moderner bildgebender Verfahren gleichermaßen lokalisierbar sind wie Verumeffekte und es sich beim Einsatz von Placebos – auch außerhalb klinischer Studien – keineswegs um eine unbedeutende Randerscheinung, sondern ein de facto etabliertes Konzept handelt. Aus rechtlicher Sicht ist der Placeboeinsatz jedoch alles andere als eindeutig geklärt, da es keine nationale Gesetzgebung gibt, die den Umgang mit Placebos im individuellen Arzt-Patient-Verhältnis expressis verbis regelt. Das vorliegende Buch untersucht die Anwendbarkeit bestehender Rechtsvorschriften, um die derzeitige Prävalenz des praktischen Tuns auf eine solide juristische Basis zu stellen. Wesentlicher Inhalt der Betrachtung ist die Feststellung der Rechtmäßigkeit des Placeboeinsatzes unter Berücksichtigung der relevanten Parameter, wie die mögliche Einordnung von Placebos unter das Arzneimittelgesetz, die Abgrenzung zwischen medizinischer Heilbehandlung und individuellem Heilversuch, die notwendige medizinische Indikation und die Risikoanalyse. Neben den Anforderungen an eine korrekte ärztliche Aufklärung werden auch Haftungsfragen adressiert und die Konsequenzen eines (un)rechtmäßigen Placeboeinsatzes – aus schadenersatzrechtlicher und strafrechtlicher Sicht – aufgezeigt. Die abschließende Interpretation der Ergebnisse aus einer eigens konzipierten rechtstatsächlichen Datenerhebung unter der österreichischen Ärzteschaft verdeutlicht den Ausgangspunkt für die reformierenden Denkanstöße der vorliegenden Abhandlung.
Before the plates. Aproximación al Neolítico Reciente en el Alto Guadalquivir a través de los sitios de Grañena Baja II y Arroyo Regordillo (Jaén, Andalucía)

Published: December 2024

Presentamos en este trabajo los sitios arqueológicos de Grañena Baja (fase II) y Arroyo Regordillo, situados muy próximos entre sí junto al cauce medio del río Guadalbullón (término municipal de Jaén). Abordamos la ocupación propia del Neolítico Reciente en ambos sitios, ajustada en cronologías radiocarbónicas a mediados del IV milenio cal AC, considerando que aspectos relacionados con las fases I y III de Grañena Baja ya han sido tratados en trabajos precedentes.
Tanto la fase II de este último yacimiento como la ocupación detectada en Arroyo Regordillo, se caracterizan por la presencia de estructuras subterráneas de planta circular, destacando una cultura material de características tecnotipológicas marcadamente diferenciadas de las conocidas para el último tercio del IV milenio cal AC en la región. Entre éstas, destaca especialmente en la cerámica el dominio de formas globulares, el uso abundante de aguadas a la almagra, así como algunos ejemplos de decoración pintada poco comunes en la Prehistoria reciente del sur de Iberia. Por su parte, la tecnología lítica se basa en una producción laminar estandarizada a presión, siendo característicos talones facetados o lisos, diferentes morfológicamente del talón diedro agudo, típico de las producciones laminares que caracterizarán la Edad del Cobre en este territorio.
La Dea Mater ibérica: iunstir y el culto al planeta Venus en el mundo ibérico
Authors: Iborra Pellín Daniel
Published: December 2024

Estos últimos años se ha avanzado en la valoración de las orientaciones astronómicas al planeta Venus de los templos y cuevas santuario ibéricos. La importancia creciente de estos testimonios plantea conocer qué nombre dieron los íberos a dicha divinidad. Este artículo relaciona datos astronómicos, iconográficos y lingüísticos que indican que el nombre de la Dea Mater ibérica pudo ser Iunstir. Esta palabra parece estar formada por los términos iun (nombre de la divinidad) y stir (“astro”), lo que relacionaría esa divinidad ibérica con el epíteto “astro”, como ocurre con la Astart fenicia. Según esta hipótesis, el nombre de la Diosa Madre ibérica sería Iun / Iunstir.

En España, la llegada de los operadores internacionales de televisión bajo demanda, a partir de 2015, alimentó la formación de un nuevo sistema televisivo. A las grandes plataformas, le siguieron operadores nacionales, repositorios de contenidos y canales temáticos de pago, que fueron creando un tejido de producción y distribución distinto. Esta investigación ahonda en las características generales de la producción de ficción seriada española en este periodo. Se interesa por variables como el volumen de producción, los canales y soportes por los que se emite, la serialidad dominante o la relación de fuerzas entre las empresas productoras. También por las características narrativas y temáticas de las producciones, que clasifica por género y subgénero. Para ello se ha realizado un censo propio, en el que se incluyen las ficciones seriadas españolas emitidas desde 2015 hasta 2021 (n = 288). Se ha generado una base de datos con 458 registros a fin de cuantificar los indicadores propuestos. Para la clasificación de las producciones por género y subgénero se han construido tipologías inductivas y a posteriori. Los resultados describen un complejo panorama de producción y distribución en el que la ficción televisiva española se ha visto reforzada no solo en términos de volumen de negocio, sino también de diversidad, originalidad y calidad. Se ha visto contagiada de los estándares internacionales, pero se perciben temáticas y narrativas vinculadas con lo local (costumbrismo, interés por la historia propia, actualidad sociopolítica, preocupaciones emergentes) que dotan a la producción española de una idiosincrasia propia. Esta etapa se presenta como el germen del momento dorado que vive la producción de ficción doméstica
Diferencias de capitales entre los estudiantes franceses de fisioterapia en Francia y España. ¿Qué dice la sociología bourdieusiana sobre las profesiones?
Authors: Rollin Jérémy
Published: December 2024

Para estudiar fisioterapia en Francia hay que superar un difícil examen de acceso. Algunos jóvenes franceses prefieren formarse en España, en universidades privadas sin oposición, antes de volver a trabajar en Francia. Esto crea tensiones en el grupo profesional francés porque genera una competición en el mercado laboral. Pero además, este artículo parte de la hipótesis de que las tensiones se explican por las diferencias de características sociales entre los dos grupos de estudiantes, formados en Francia o en España. La investigación se basa en el análisis de los resultados de un cuestionario administrado a estudiantes de los dos países. En muchos indicadores, los

Published: December 2024

The results of preliminary studies of Bulgarian natural raw materials as possible sources for the synthesis of high-quality ceramics of the “yellow” pavers type are presented. For the purposes of comparative analysis, a short geological-mineralogical literature review of Bulgarian and Hungarian deposits of marl raw materials and of Bulgarian deposits of non-marl raw materials rich in magnesium is made. The capabilities of the X-ray fluorescence (XRF) analysis and the powder X-ray diffraction (PXRD) techniques for the rapid acquisition of reliable data on the phase-chemical characteristics of the investigated materials have been demonstrated. A relation is made between these characteristics and the physicochemical and mechanical properties of possibly synthesized products (color, hardness, etc.). Considerations for choosing methods for processing the primary data are presented, allowing for some simplification without affecting the reliability of the results. The latter have been analyzed and possibilities for improving the qualities of the starting raw material have been discussed in order to obtain products with desired characteristics.

Assarel porphyry copper deposit is located in the Panagyurishte ore district, Central Srednogorie, which is a part of the Late Cretaceous Apuseni–Banat–Timok–Srednogorie magmatic and metallogenic belt. This study reports a new data on the epithermal high-sulfidation ore mineralization described previously as “specific” and “rare”. The ore mineralization is associated with advanced argillic alteration and is represented by enargite, colusite, sulvanite, bornite. They occur as thin veinlets brecciating or crosscutting earlier small disseminated euhedral/subhedral to anhedral pyrite in quartz or subhedral/anhedral pyrite nest-like aggregates with zunyite, gypsum, rutile. Bornite is replaced by chalcocite and covellite, and enargite by covellite. Enargite contains Sn, Sb, Te, while colusite occurs as two distinct chemical varieties: 1) Sn-rich and Mo-bearing, with lower As content, and 2) Sn-poor, Ge-bearing, As-rich. Both varieties have 0.1–0.2 wt% Sb. Bornite and chalcocite contain small amounts of Se. Pyrite spatially associated with this mineralization is enriched in Cu, Co, and Ni, with Co/Ni and Co/As ≥ 2.

Published: December 2024

Mineralogical and geochemical LA-ICP-MS trace element study was conducted on sulphides from the Djurkovo Pb-Zn deposit, Central Rhodopes. The studied ore mineralization consists mainly of sphalerite, galena, pyrite, and chalcopyrite precipitated in three mineral parageneses, part of the main polymetallic and quartz-carbonate stages as it is indicated by the textural relationships. The first paragenesis is developed as massive metasomatic replacement occurring in the marble horizons and consisting of sphalerite, galena, and chalcopyrite. The second para­genesis represents later veins composed mainly of quartz, pyrite, galena, and sphalerite crosscutting the metasomatic bodies. The third paragenesis represents late thin carbonate veins with translucent greenish sphalerite (cleiophane) and pyrite/marcasite aggregations, parts of the quartz-carbonate stage. The trace element signatures of the studied sphalerites indicate incorporation of Fe, Cd, Mn, Cu, Co, In, and Hg. Important elements in pyrites are Co, As, Pb, Mn, and Se. Chalcopyrite is the main carrier of Ag among the studied sulphides. The latest pyrite/marcasite aggregations show significant incorporations of As, Sb, and Tl.

Published: December 2024

The study is focused on the Smilovene pegmatites, targeting estimation of their rare element potential. These bodies bring rare-metal mineralization with LCT geochemical signature and mineral association of albite, oligoclase, microcline, quartz, muscovite, beryl, garnet, fluorapatite, zircon, columbite, samarskite-(Y), monazite-(Ce), magnetite, and gahnite. Late chlorite, prehnite, titanite, and bertrandite were established. Beryl is characteristic with high amounts of FeO, Na2O, MgO, ZnO, F, and traces of Cs, and Li. Spessartine-almandiness is enriched in Y2O3, TiO2, ZnO, P2O5, REE, Li, Ge, Ga with typical inclusions of apatite, monazite-(Ce), zircon, magnetite, gahnite, ilmenite, uraninite, and Nb-bearing phases. Significant contents of HfO2, UO2, REE2O3, ThO2, and traces of Y, Sc, Ta, Zn, Nb, Be, Li and inclusions of uraninite and cheralite are common in zircon. Minor amounts of Cl, MnO, Y2O3, and REE2O3 attribute to fluorapatite. Except the dominant Ce2O3 in monazite-(Ce), La2O3, ThO2, and Gd2O3 are established. The presence of rare-metal mineralization in the Smilovene pegmatites confirms their potential as a critical/strategic elements concentrator, feasible for further exploration and possible exploitation.
