Цель. Изучить роль неформальных связей как источника сопротивления менеджмента среднего звена цифровой трансформации с учётом контекста изменений на примере трансформации логистической компании в платформу. Методология и дизайн исследования. Индивидуальная реакция менеджеров среднего звена в ответ на изменения сильно зависит от ситуационных обстоятельств и должна изучаться с учётом контекста. Руководитель проекта изменений вместе с командой управления проектом проводил глубинные интервью с 12 респондентами и предоставил авторам статьи доступ к своим записям, которые были сделаны во время интервью. Основываясь на этих данных, авторы статьи, применив метод целенаправленной выборки, отобрали шесть случаев — кейсов, иллюстрирующих ценную информацию о различных формах поведения отдельных менеджеров, о социальной динамике в фирме в период изменений, и о том, как сопротивление было преодолено. Авторы строят анализ на концепции насыщенного описания К. Гирца. Результаты и практическая ценность. Анализ представленных случаев показал, что сопротивления менеджеров среднего звена уникальным образом переплетено с событиями, сопровождавшими процесс цифровой трансформации. Оно может быть связано со стремлением сохранить личные связи с клиентами, перевозчиками и коллегами по работе, так как изменения, необходимые для перехода к платформенному бизнесу, меняют роли и обязанности менеджеров организации и, следовательно, могут угрожать их сетям неформальных связей с внутренними и внешними стейкхолдерами. Решения, нацеленные на приспособление персонала к работе в новых условиях, а не на прямое и открытое противостояние сопротивлению, могут привести к созданию новых сетей и источников неформальных связей у менеджеров. Такие действия способны превратить ключевой персонал с высоким социальным положением среди коллег в агентов изменений.
Scientific Narratives in the Study of Student Time Management: A Critical Review
Authors: Romero-Pérez Clara , Sánchez-Lissen Encarnación
Published: July 2022

Effective time management plays a major role in the performance society, and not only psychological, but also socio-cultural and pedagogical factors are involved in students' effective organization of time. Mainstream scientific discourse has argued that effective learning depends to a large extent on students' organizational skills. However, researchers have paid scant attention to the socio-cultural and pedagogical aspects that are involved in the development of these skills. The purpose of this article is to critically analyze the dominant scientific narratives on the study of the effective use of time by students. To this end, this study was designed based on a critical review of the literature from 1990 to 2021. The Web of Science and Scopus databases were consulted. A total of 51 papers met the inclusion criteria. The results suggest that learning to organize and optimize academic time is important for social coordination, well-being and achievement of students' academic and life goals. However, the acceleration of instructional time has a major emotional impact on the school population. The conclusion is the need to investigate the subjective and collective experiences of students on the emotional impact that speed, work overload and multitasking have on their academic and personal lives.

Published: July 2022

La violencia hacia la pareja es un fenómeno que se ha analizado desde diversas perspectivas, entre ellas se encuentra la Violencia hacia el Hombre (VhH) en la pareja, objeto de estudio al que se le ha otorgado poca relevancia social y académica en diversas regiones. El presente estudio tiene como propósito identificar los aspectos metodológicos y hallazgos más relevantes de la VhH en los estudios realizados en las últimas dos décadas en Latinoamérica. Siguiendo las directrices del Modelo PRISMA, se llevó a cabo una revisión sistemática a través de una búsqueda de trabajos en seis bases de datos. Las referencias iniciales fueron 426, las cuales se sometieron a un análisis por medio de un proceso de depuración donde, finalmente, se obtuvieron 16 artículos que cumplieron con los criterios de inclusión y exclusión. Los principales resultados destacan que, recientemente, la comunidad científica en América Latina ha prestado más atención a las víctimas masculinas realizado aportes que permiten cuestionar la minimización social, académica y científica del fenómeno. Se discuten los resultados destacando que el estigma social es lo que sigue dificultando el reconocimiento de las víctimas masculinas como un objeto legítimo y válido de investigación.
Radicalisation in Immigrant Youth: Differential Influence Analysis of Psychosocial Factors
Authors: León Almudena Macías , Cosano Rivas Francisco , Durán Durán Auxiliadora
Published: July 2022

The radicalisation of young immigrants in Europe is a phenomenon of scientific and political relevance. The study aimed to analyse the degree of consensus on the differential influence on the radicalisation process of various factors (attitudinal, contextual, historical and protective), primarily included in the VERA-2, related to multiple socio-demographic categories and the processes of radicalisation in opinion and action. Applying a Delphi analysis methodology, the results point to the difficulty of reaching a consensus on the differential influence of the factors that affect the radicalisation of young migrants according to the categories examined. This consensus is appropriate concerning the distinction between radicalisation in action and radicalisation in opinion, showing the multiplicity of influential factors, especially in the case of radicalisation in opinion. The importance of protective, contextual, and attitudinal factors is evident for this type of radicalisation, while for radicalisation in action, a high consensus is reached on historical and contextual factors. Interventions aimed at the attitudinal sphere, rejection and prevention of violence, active policies of social inclusion, and spaces for intercultural dialogue and community participation are proposed as lines of work to prevent the radicalisation of young immigrants.

En marzo de 2022, un 60% de personas en España se identifican como religiosas (creyentes). Este porcentaje es el más bajo de los datos disponibles en las series históricas. En el año 2000, era del 80%, mientras que en 2019 era del 70%. Casi todas las personas que se identifican como creyentes indicant que son católicas. La variabilidad de la identificación religiosa puede verse por género, edad, estudios alcanzados e ideología. Se han fusionado 102 archivos de datos del Centro de Investigaciones Sociológicas (CIS) en España y obtenido una muestra de 340.532 personas entre enero de 2013 y febrero de 2022. Este archive incluye información adicional de la ocupación de las personas entrevistadas, de su situación professional y de su actividad económica. Con esta información hemos creado un modelo de clases sociales (muestra de 268.261 personas) siguiendo la clasificación de Erikson, Goldthorpe y Portocarero (EGP). Los resultados muestran que la identificación religiosa varía significativamente por clases sociales: los de clases sociales altas se identifican menos como personas religiosas (creyentes).

Published: July 2022

In the recent past and in today’s world, the internet is advancing rapidly and is easily accessible; this growth has made the social media platforms such as Facebook, Instagram, Twitter, and LinkedIn widely used which produces big data. This requires both topic Detection applications in order to access the required information, as well as community detection practices in order to provide collective services to communities that can be referred to as individuals with similar interests and opinions over the same subject. Therefore, it is vital for researchers to conduct research on topic detection and community detection research areas in social networks and to develop methods and techniques for problem-solving. In this study, a systematic and in-depth literature review is provided on studies that conduct topic and community analysis on social media platforms to provide a comprehensive overview of the given areas. Most of the studies to be analyzed are selected from articles using machine learning-based models that are known to achieve successful results in practice. As a result of the analysis of these studies; it has been concluded that a single model cannot be proposed in the area of topic detection and that the appropriate model should only be selected or created in a problem-specific way, taking into account all the characteristics of the given problem, while the Louvain method seems to stand out with its results in terms of performance in the area of community detection.

Published: July 2022

The challenge of modeling and rendering required for high-quality 3D visuals leads to the use of new environments. Working with web browsers and allowing real-time interaction, 3D graphic libraries have become platforms where design and software can be executed together. The aim of the study is to explore the usage ways of the web environment, and their potentials in 3D visualization. After examination of declarative and imperative classification in 3D graphics, the focus is on the WebGL standard, which is imperative and has recently come to prominence in web application and content production. In this context, discussed approaches towards the usage of interactive 3D web graphics in the representation process of designs are: 1. We examined web graphics libraries that allow real-time interaction and 3D modeling through scripting. 2.We focused on tools that are developed as plug-ins to 3D modeling programs on desktops and provide web integration. 3. We discussed the library-based editors which both offer models in a web browser and allow coding simultaneously. The general framework prepared in the study presents the use of these approaches in modeling, visualization, and presentation in the context of web graphics libraries and discusses their advantages and disadvantages. This discussion is a preliminary study of more comprehensive research that can be prepared for the development of next-generation desktop and web-based modeling approaches in the context of using web browsers as visualization media.

Bireylerin temel hak ve özgürlüklerini genişletmek amacıyla gündeme gelen bireylere ait verilerin korunması kavramı “canlı bireyler” ile kısıtlanmış olması özellikle sağlık ile ilgili araştırma ve uygulama konularında bir takım belirsizliklere ve tartışmalara yol açmıştır. Tartışmaların odağında ise hem Türkiye mevzuatında hem de Avrupa mevzuatında “gerçek kişi” tanımı yer almaktadır. Bu tanımın doğrudan kapsamı içinde yer almamakla beraber, bu tanımla çeşitli nedenler ile kesişen ve örtüşen iki temel durum söz konusudur. Bunlardan birisi doğmamış bebekler ile ilgili kişisel verilerin korunması konusu, bir diğeri ise ölmüş kişilere ait verilerin korunması konusudur. Bu çalışmada, doğmamış bebekler ve ölmüş kişilere yönelik kişisel verilerin Türkiye ve Avrupa’da ele alınış ve işleyiş biçimleri irdelenmiştir. Bunların yol açtığı sorunlar değerlendirilmiş ve çözümsel düzenleyici yaklaşımlar ortaya konmuştur.

The aim of this work is the removal of phosphates from an aqueous solution by adsorption on a new, inexpensive adsorbent, calcium oxide. We have also shown interest in the choice of removal method, which is adsorption. The kinetic study of the removal of phosphate ions by adsorption on calcium oxide allowed us to calculate the value of adsorption capacity as a function of the parameters affecting adsorption: Amount of adsorbent, initial concentration of phosphate ion solution, pH of the mixture and temperature. The study of adsorption isotherms showed that the Freundlich model is the most appropriate for the phenomenon of phosphate ion adsorption. Modeling of the kinetic data by the pseudo-first order and pseudo-second order equations shows that the adsorption process is best described by the second order equation. Thermodynamic parameters such as enthalpy ΔH°, entropy ΔS° and free enthalpy ΔG° were also evaluated to determine the nature of adsorption. The results show that the adsorption process is a spontaneous and endothermic physisorption.

1,3,5-Triaryl-2-pyrazoline derivatives with a pyridine ring in position 1 and 2-benzimidazolyl or 2-benzothiazolyl bicycles in position 3 were synthesized. Spectral properties in solvents of similar polarity, i.e. aprotic acetonitrile and in protic methanol, were studied, complexation with cadmium and mercury ions in acetonitrile was elucidated as well. Quantum-chemical modeling with application of the elements of Bader's atoms-in-molecules (AIM) theory of the title molecules conformational structure and 1:1 stoichiometry complexes formed with polyvalent metals of various nature (Mg, Zn, Cd, Pb, Hg, Ba) was conducted. The principal possibility of “nitrogen-sulfur” switching of the metal ions binding sites for the benzothiazole derivative was revealed, and makes possible to classify this compound as “smart ligand”.

Despite the nationwide effort provided to combat the COVID-19 pandemic, we have yet to approve a specific antiviral treatment against the SARS-CoV-2. We have studied the molecular interactions between two anti-HIV-1 natural drugs, +(-) calanolide A and -(-) calanolide B, and the active site of 3CLpro through a computational docking method. Our promising results show that the two compounds of this study are potential inhibitors of the SARS-CoV-2 3CLpro through strong binding to its catalytic dyad. Considering its progress in clinical trials as an anti-HIV-1 treatment, we suggest that +(-) calanolide A is a good candidate for the treatment of COVID-19.

Authors: Tursunov Anisjon I. , Nazarov Toirkhon Kh. , Rychkov Ivan V.
Published: July 2022

BACKGROUND: Retrograde intrarenal lithotripsy is a modern method of endoscopic treatment of patients with nephrolithiasis, whereas some aspects of its use remain the subject of discussion.
AIM: To reveal the advantages and disadvantages of retrograde intrarenal lithotripsy in patients with nephrolithiasis having high-density calculi.
MATERIALS AND METHODS: A retrospective and prospective analysis of treatment of 260 clinical cases of high-density kidney stones by transurethral contact pyelocalicolithotripsy was conducted. In all patients, kidney calculi were diagnosed and detected, ranging in size from 8 to 20 mm (average 15.4 mm) and density from 1105 to 1634 HU. Patients were divided into the main group and control group and further into two subgroups according to the lithotripsy method. The main group underwent transurethral contact pyelocalicolithotripsy according to our improved method and the control group according to the standard method. The main subgroup of ultrasonic lithotripsy and the control subgroup included 80 and 50 patients, respectively. The main subgroup of laser lithotripsy and the control subgroup included 50 and 80 patients, respectively.
RESULTS: In 223 (85.8%) patients, it was possible to completely crush the calculi and eliminate them from the urinary tract. The stone-free rate in the main group was 96.9% (126 patients) after the first operation, including 96.2% (n = 77) in the ultrasonic lithotripsy subgroup and 98% (n = 49) in the laser lithotripsy subgroup. In the control group, the SFR value was 74.6% (n = 97), including 72% (n = 36) in the ultrasonic lithotripsy subgroup and 83.2% (n = 61) in the laser lithotripsy subgroup. Intra- and postoperative complications were observed in 74 (28.5%) patients, and none had grade IV and V complications according to the adapted ClavienDindo classification. The frequency of complications was significantly lower in the main group and those who underwent laser lithotripsy. The relationship of postoperative complications with intraoperative damage to the structures of the pelvicalyceal system of the kidney has been established.
CONCLUSIONS: Transurethral contact pyelocalicolithotripsy is an effective and relatively safe method of treating patients with nephrolithiasis having high-density calculi. The proposed improved surgical intervention has advantages over traditional methods.

BACKGROUND: The frequency of occurrence reaches premature ejaculation (PE) in young men reaches 30%. Increasing the effectiveness of treatment of patients with PE is one of the important problems of urology.
AIM: Evaluation of the effectiveness of treatment of young patients with premature ejaculation with the phosphodiesterase 5-type inhibitor Tadalafil-SZ in monotherapy and in combination with behavioral therapy, as well as its comparison with the appointment of only behavioral therapy and placebo.
MATERIALS AND METHODS: We observed 70 men with premature ejaculation aged 18 to 25 years. All patients were divided into 4 groups. Patients of the 1st group (n = 20) were prescribed Tadalafil-SZ at a dose of 5 mg once a day as monotherapy, patients of the 2nd group (n = 20) received behavioral therapy according to the startstop method; patients of the 3rd group (n = 20) were prescribed a combination therapy with Tadalafil-SZ at a dose of 5 mg per day together with the startstop behavioral technique; patients of the 4th group (n = 10) were prescribed a placebo. The duration of treatment is 30 days. Control examinations were performed before the start of treatment, immediately after its completion and 2 months after the end of therapy. To assess ejaculatory function the PEDT and AIPE questionnaires were used, as well as the IELT test.
RESULTS: After the end of the 30-day course of treatment in patients of the 1st and 3rd groups, a significant increase in the duration of sexual intercourse by 22.5 times was noted compared with the values before treatment, as well as with the values in patients of the 4th group who received placebo. In patients of the 2nd group, we did not notice significant changes in comparison with the indicators before treatment in terms of the total scores of the PEDT questionnaire and the results of the IELT test, however, an increase in the total scores of the AIPE questionnaire was found. In patients of the 4th control group, there was no improvement in any of the tests performed. 2 months after the end of treatment, patients of the 1st group noted a return to the initial duration of sexual intercourse. The effect of the treatment was noted only in patients of the 3rd group, in whom during the control examination after 2 months the duration of sexual intercourse was significantly higher compared to the initial values before the start of treatment.
CONCLUSIONS: The results of the study indicate the high efficiency of the phosphodiesterase 5-type inhibitor Tadalafil-SZ in the treatment of patients with premature ejaculation. The best results of treatment were achieved with the combined use of drug and behavioral therapy.

The review article provides definitions and presents current data on the biological significance of the microbiome and microbiota of urine. The urinary microbiota is less well understood than the intestinal microbiota, but its biological role is complex and multifaceted. To date, its importance in the formation of colonization resistance, which prevents the invasion of uropathogens, is obvious. An analysis of methods for assessing the microbiome and microbiota of urine was carried out. The shortcomings of widely used standard microbiological research methods are shown. The method of 16S rRNA gene sequencing is described in detail. Information about the gender characteristics of the urine microbiota and the results of its study in healthy women and men are given. Further progress in the study of the urobiome is associated with the acquisition of new technologies for genomic research and the development of bioinformatics.

Background: Dermatologic diseases are generally managed at an outpatient clinic and most cases have very low
mortality rates. However, some dermatologic diseases are life-threatening and only a few studies have assessed
their mortality rates and associated factors.
Objective: To investigate the mortality of inpatients with dermatological diseases.
Methods: This retrospective study was conducted by reviewing the medical records of patients who died in the
dermatology ward at a tertiary hospital in Korea in a period of 17 years. Patient demographics, dermatologic
diseases, immediate cause of death, comorbidities, and clinical factors related with mortality were investigated.
Results: The total number of inpatients in the dermatology ward during the study period was 740. Thirteen
patients (1.76%, 5 men and 8 women) expired while they were admitted in the hospital. The median age of the
patients was 63.8 years (range, 18 to 86), and the maximum number of deaths occurred in patients over 70 years
old (7 out of 13 patients, 53.8%). Drug reactions were the most common dermatologic complication resulting in
admission, followed by bullous disease, generalized pustular psoriasis, and dermatomyositis. Most patients had
multiple comorbidities, including hypertension, diabetes mellitus, kidney disease, and angina. Sepsis due to infection
was the most common cause of death.
Conclusion: Infection was the most important factor contributing to mortality. Old age, immunosuppression, and
comorbidities were important factors that contributed to mortality in dermatologic inpatients.
La passione per l’umano. Empatia e persona in Edith Stein
Authors: Pezzella Anna Maria
Published: July 2022

A passion for the person led E. Stein to investigate empathy and the human person. Empathy is an act that allows recognition of the other, but not inner participation in his or her experience, which is proper to sympathy. The value of empathy lies in being not only a way of access to the estranged subject but also a way of understanding oneself, because only through relationship with others is self-knowledge possible. After such an examination, the human person is described, which, formed by the unity of body soul and spirit, escapes from any mechanistic analysis because its ultimate essence is the freedom before which God Himself stops. Such an investigation is accomplished with the Husserlian lesson in mind, on which Stein has been nourished, and with some aspects of the philosophy of M. Scheler who has been a stimulating ground of comparison for her.
Esencia y posibilidad de la intersubjetividad en Edith Stein y Max Scheler: Presentificación empática y percepción simpatética en la Fremderfahrung
Authors: Velázquez González Juan
Published: July 2022

This paper claims that phenomenon of empathy (Einfühlung), described by Edith Stein, and phenomenon of sympathy (Mitgefühl), analysed by Max Scheler, offer complementary insights into the essence of intersubjective link and into the conditions of possibility for experiencing the Other (Fremderfahrung). Stein’s and Scheler’s phenomenological analyses took place in the context of Husserlian researches on intersubjectivity problems, following a critical attitude towards modern theories of sympathy and towards Lipps’ psychology of empathy as well. However, Scheler’s and Stein’s standpoints got also together on the basis of a philosophical affinity and a critical shared position with regard to Husserl’s transcendental constitution of phenomenology. According to Stein to empathize involves a particular kind of apperception that actualizes the original contents of living experiences of the alien body in a non-original way, whereas for Scheler to sympathize refers to the manner of feeling with others some shared emotions, in an original way, thanks to inner perception of the living life of the neighbour, as another condition of possibility for the Fremderfahrung.
Entre Husserl y Tomás de Aquino. Aspectos metafísicos y epistemológicos del diálogo entre fenomenología y escolástica según Edith Stein
Authors: Ramos Gómez Miriam
Published: July 2022

The fundamental program of Stein’s philosophy after his conversion was the relationship between modern philosophy and scholasticism. This article deals with new metaphysical and epistemological aspects of Stein’s work that reflect the encounter between both philosophical currents, starting from her reading of Thomas Aquinas’ De veritate, which have not yet been treated in the Edith Stein Forschung. Thus, from the metaphysical point of view, the question of the relationship between unity and multiplicity and the problem of the conditions of possibility of organic development are identified. And from the epistemological point of view, the following relevant aspects are raised: the starting point of philosophizing; the principles of knowledge; the extent to which habit influences knowledge; the question of whether angelic knowledge can serve to clarify human knowledge; the relationship between mathesis universalis and divine knowledge; the relationship between abstraction and intuition; and the critique of the Heideggerian interpretation of the concept of truth in the philosophical tradition.
Análisis de la noción de virtualidad en el contexto de una fenomenología de la conciencia de imagen: un estudio steiniano
Authors: Alvarez Mateos Maria Teresa
Published: July 2022

Edith Stein´s philosophical work was largely devoted to the synthesis of the phenomenological thought of her master Edmund Husserl with thomistic scholasticism. This work tries to continue the motivation of that Steinian synthesis project in relation to one of the notions dealt with in the philosophy of Thomas Aquinas that may help to clarify the phenomenological analysis about imagination and image consciousness: namely the idea of virtuality. It will be argued that this notion of “virtuality” used by Thomas Aquinas can characterize the mode of being of some components of pictorial images.
La questione del male nella filosofia di Edith Stein. Politica, etica e metafisica
Authors: Bello Angela Ales
Published: July 2022

In my paper I suggest to begin “von unten”, from the human associations, particularly the political ones in which we live every day and that we consider positive or negative, as Edith Stein wrote in her work “On the State”. In order to understand the meaning of our judgments on good and evil it is necessary to go deeper and to explore the origin of evil in an ethical, metaphysical and religious sense. Therefore, I start from the analysis of Edith Stein’s essential description of community and in particular the one which is at the basis of the State in order to discover the difficulties to build a State according to its essential structure because of the ethical evil. According to Stein to understand the birth and the meaning of this kind of evil and of evil in general it is necessary to go on as far as the metaphysical comprehension of it as she explains in Finite and Eternal Being.
A essência do eu: uma análise da constituição do si humano em Edith Stein e Hedwig Conrad-Martius
Authors: Tricarico Clio
Published: July 2022

In her Der Aufbau der menschlichen Person [The Structure of the Human Person], Edith Stein describes the human person as a spiritual and free being. These two aspects highlight the essential role of the I as (i) being spiritual means to be “awake” and “open”, thus entailing, respectively, the intentional characters of attention and openness to “exteriority” and “interiority”; that is, on the one hand, the I is open to otherness and to the world of values, and, on the other, it is self-conscious, be it on a unreflected level or by reflecting on its own acts; and (ii) being free is related to the power of the will, i. e. to the I can [ich kann], in the sense that the individual gains control over certain factors imposed by the natural realm (psychophysical sphere), which is fundamental for the self-formation of personal character. Intentionality and freedom are thus essential traits of the I, whose basis, according to Hedwig Conrad-Martius, implies in examining its original constitutive source, namely the pneumatic substance. We hereby intend to present how the basic elements that are intrinsic to the ontic-ontological foundation of the human self relate to each other in both authors’ phenomenological approaches.
Leib mehr als Körper. Bemerkungen zu Edith Steins Anthropologie
Authors: Gerl-Falkovitz Hanna-Barbara
Published: July 2022

‘What is the human being?’ Edith Stein (1891-1942), master-disciple of Husserl, developed a remarkable phenomenology, especially in refer to the interrelation of human body, soul, self-concept, and divine giftedness. In German the conception of body is twofold: It can be understood as „Körper“, that means as an objective entity, or instrument. And body can be understood in a deeper sense: as „Leib“ = living body, etymologically related to Leben (life), including soul, integrating spirit – while „Körper“ could be also a dead body. Leib reveals itself ascending from the non-living to the living entities, from vegetative and animal life to human being including freedom and self-consciousness. Therefrom human being can activate its access to the creative origin, to the original light. This is Edith Stein’s answer to the auto-construction of an I, which regards its own body only as an instrument or masque on a meaningless stage.
Anthropologie et éducation selon Edith Stein: une approche de la destination surnaturelle de la personne humaine
Authors: De Rus Eric
Published: July 2022

Stein’s theory of education is inseparable of an anthropology characterized by its metaphysical dimension. Her existential analysis of the human finitude, quite different from Heidegger’s philosophy of existence, brings to light the essential opening of the finite being on the eternal being as its inner principle and foundation. The importance of the interiority of the soul is crucial to appreciate the meaning of education as an entire «recreation» of the human being from its depth. Our contribution is an approach of that process of recreation by the formative force of the divine grace which represents what Stein calls the «supernatural destination» of human person.
El reposo y la seguridad en Dios. Bases para una fenomenología de la religión en Edith Stein
Authors: Sánchez Muñoz Ruben
Published: July 2022

Although Edith Stein did not write a treatise exclusively devoted to the phenomenology of religion, the subject appears in her works and gives valuable indications for understanding the phenomenon of religion. In this article, we will review two of these experiences. One of them appears in Psychische Kausalität when speaking of the experience of “at rest” (Ruhens). The second appears in the Einführung in die Philosophie and Stein calls it experience or feeling of “secutity” (Geborgenheit). In both we can see Stein´s reception of Adolf Reinach´s notes on the philosophy of religion, but, beyond that, they are experience that describe essential notes on the relationship of man with God. In this sense, our purpose is to show how important it is for Edith Stein´s description of religious experience to describe in the form of a “feeling” that touches the interior of the person, i.e. his soul or Gemüt. From there, we want to propose that the phenomenology of religion that Edith Stein develops opens to the understanding of the person understood as interiority and that it is from there that the person feels touched by God. The human person seeks God and the encounter with Him gives him the calm, the security and the shelter that he cannot find elsewhere.
Paleoecology of Lower Miocene coralline red algae-rich grainstone facies in the Qom Formation (Vartun section, central Iran)
Authors: Rahiminejad Amir Hossein , Yazdi Mehdi , Ghosh Amit Kumar
Published: July 2022

In this paleoecological study we focused on coralline red algae-rich shoal grainstone facies in the Lower Miocene (Aquitanian) carbonates of the Qom Formation in the Vartun section in central Iran. The identified coralline red algae are mainly non-geniculate, although very rare geniculate forms of corallines were also recognized in thin section analysis. The identified algae are represented by Melobesioideae (Lithothamnion cf. valens, Lithothamnion cf. rovereoti, Lithothamnion cf. peleense, and Lithothamnion spp.), Mastophoroideae (Neogoniolithon sp., Spongites spp., and Spongites cf. fruticulosus), Sporolithon spp. (Sporolithon spp. and Sporolithon cf. airoldii), and geniculate coralline (Corallina). The algal taxa mainly display fruticose and lumpy growth forms. The dominance of the former is consistent with high water energy in the identified shoal environment. The presence of Lower Miocene algae indicates that deposition of carbonates took place in warm tropical to subtropical waters in a euphotic marine environment during the Aquitanian. Likewise, high water energy and sediment agitation resulted in taphonomic features such as fragmentation, abrasion, and disarticulation.
