Keterbatasan fasilitas pada Usaha Mikro Kecil dan Menengah (UMKM) menyebabkan beberapa UMKM masih mengandalkan tenaga manusia pada aktivitas kerjanya. Faktor ergonomi masih kurang diperhatikan, sehingga kemungkinan terjadinya nyeri muskuloskeletal cukup tinggi. Penelitian dilakukan pada bengkel UMKM dengan nama Sumber Boga Wijaya yang terletak di daerah Duren Sawit, Jakarta Timur. Dilakukan analisis pada 2 postur kerja, yang pertama postur kerja berdiri membungkuk. Berdasarkan hasil penyebaran kuesioner NBM, ditemukan bahwa para pegawai merasakan sakit pada area leher, punggung, pinggang, bahu, lengan bawah kanan, dan pergelangan tangan kiri. Pada analisis REBA didapatkan skor 5 (level medium risk), pada analisis OWAS didapatkan skor 2. Postur kerja kedua adalah postur kerja berjongkok, dari hasil penyebaran kuesioner NBM ditemukan bahwa para pegawai merasakan sakit pada area leher, bahu, pinggang, punggung, bokong, pergelangan tangan, dan kaki. Pada analisis REBA didapatkan skor 9 (level high risk), pada analisis OWAS didapatkan skor 2. Dari hasil perancangan rak meja kerja skor REBA berkurang menjadi 3 dan OWAS berkurang menjadi 1, yang berarti rak meja kerja dapat menopang postur kerja ke level yang aman. Rak meja kerja juga dapat menggantikan fungsi rak material habis pakai sehingga mempermudah akses masuk mobil ke area indoor bengkel.

Authors: Yunina Ekaterina Aleksandrovna
Published: May 2023

Through the analysis of epistolary documents, the author determines the information component of letters and perception of war by the Siberian combatants: weekdays and holidays in the field, adaptation behavioral strategies, emotional state, and transformation of mindset. The work is based on application of the techniques of military psychology, history of everyday life, historical-anthropological approach and text analysis. The sphere of personal human experiences are analyzed in the context of extreme conditions for the first time. The novelty of this work is defined by introducing into the scientific discourse of a complex of epistolary documents from the family archives of Tobolsk residents, which have not been previously subjected to scientific analysis. The specificity of communicative process, generation of information, emotional coloring of epistles directly depended on situational factors and addressing of correspondence; receiving a letter became the key event within the realm of daily life in the front. The attributes of soldierly letters contained consolation of relatives, recommendations on maintaining the household in case of death of the combatants, description of life in the field, recreation culture. In the atmosphere of potential danger to life, took place the process of reassessment of the fundamental human values, formation of views on the nature of war, personal aspects of its perception. These problems were solved based on the level of education, professional and social affiliation, intellectual capabilities of the addressers. The adjustment to military reality was accompanied by the negative form of stress, development of the habit to extreme existence. The form of written communication allowed realizing intra-familial socio-demographic role common to the traditional binary gender system. The distinct peculiarity of Tobolsk soldier consisted in understanding of spiritual connection with birthplace; the sense of compatriotism became much stronger.
Anton Vladimirovich Kartashev as a publicist and social activist of the early XX century: analytical review of articles in the “Russian Word” (1911-1913)
Authors: Vorontsova Irina Vladimirovna
Published: May 2023

This article is a sequence of publications on the role of Anton Vladimirovich Kartashev in religious movement for the Russian church reform of the XX century. The subject of this research is his journalistic activity during the 1911-1913. After participating in the Petersburg religious-philosophical gatherings, Kartashev joined the intelligentsia movement for the church reform; tried his hand at journalism; and picked the topic “Russian Church and Modernity” to write about for the liberal “Russian Word”. Observing Kartashev’s publicistic writing the author underlines his role as a social activist in the movement for church reform. For studying the systemic approach of A. Karthashev towards the problem of church reform in Russia, the author applies the historical method allowing to correlatie the evens of the history of Russian Church, crisis stage of religious movement and response in Kartashev’s publicistic writings. The period from 1911 to 1913 is one of the insufficiently studied periods in social activity of the future Minister of Religious Confessions of the Provisional Government and the last last Ober-Procurator of the Most Holy Governing Synod of the Orthodox Church in Russia (1917). The content of his works during this period were not viewed in the context of the upcoming church reform. However, it demonstrated Kartashev’s ideas on what impeded the Russian Church in becoming the center of historical-cultural and economic modernization of Russia.
Francisco Javier Clavijero (1731-1787) and the Society of Jesus: the impact of order upon life and works of the New Spanish historian
Authors: Veselova Irina
Published: May 2023

Francisco Javier Clavijero is a New Spanish historian, philosopher and a member of the Jesuit order. His most famous work became the “Ancient History of Mexico” published in Cesena in 1780-1781. Clavijero wrote it during his stay in Italy after the expulsion of Jesuits from Spain and its overseas colonies in 1767. The article examines Clavijero’s activity within the framework of his religious career as a member of the Society of Jesus. Based on the analysis of archival and published sources, the author determines the milestones in establishment and development of the New Spanish historian as a member of one of the most influential Catholic monastic orders. The Society of Jesus played the pivotal role in life and creative path of Francisco Javier Clavijero. The atmosphere, prevailing in the Jesuit collegiums in the middle of the XVIII century, contributed to the development of philosophical and scientific knowledge. In virtue of joining the order, Clavijero met the prominent contemporaries and took a great interest in studying the history of pre-Columbian civilizations. Even despite the uneasy relations with the primates, Clavijero remained entirely faithful to the order, for which he permanently left New Spain.

Authors: Baranov Evgeny Yurievich
Published: May 2023

The goal of this research lies in identification of the key problems of modern historiography with regards to the history of population migration in Ural in the XX century. The author analyzes the results of study of migration history in the region, determines the range of questions within the problematic field of the research, as well as the leading vectors of research. An attempt is made to shape future prospects of research work on the topic of migrations in Ural. The relevance of the article is substantiated by the possibilities of fundamental understanding of the historical and modern trends of population migration and scientific conceptualization of the history of migrations in the XX century. The migration of population in Ural in the centenary historical retrospective have not been previously been an independent subject of historiographical analysis. The conducted study demonstrates that the scholars determined the migration, its key factors and directions; suggested the variations of periodization of the history of migration in Ural; studied the role of migrations in demographic development of the Ural regions at different historical periods. The article highlights the main problems of historiography: exodus, evacuation and re-evacuation, migration policy, “migration transition”, migrations of urban and rural population, roles of migration in urbanization processes, formation of regional population, ethnic specificities of migration. It is established that significant attention of the historians is dedicated to the study of migrations in the 1920’s – 1930’s, as well as the years of the Great Patriotic War. The research carries fragmentary character. Its prospects are associated with the detailed examination of migrations in the Ural regions, and fundamental generalization aimed at identification of patterns and mechanism of the transformation of migrations, as well as the formation of their coherent picture in Ural in the XX century.

Khlystovshchina in the context of F. M. Dostoevsky’s ideology of pochvennichestvo
Authors: Snigireva Svetlana Dmitrievna
Published: May 2023

The subject of this research is the themes of F. M. Dostoevsky’s writings on Khlystovshchina (Christ Faith), as well as his views on this sect. The object of this research is the articles “A Writer’s Diary”, novel “The Idiot”, draft notes to the poem “The Life of a Great Sinner”, main idea of the novel “Atheism”, as well as articles in the periodicals of the 1860’s dedicated to Khlystov heresy. The goal of this work consist in determination of the writer’s opinion on Khlystov heresy in the contexts of the ideology of pochvennichestvo (return to the native soil). Using the philological and historical methods, the author describes correlation of the core ideas of Dostoevsky’s writings with the history of non-Orthodox religious movements in Russia if the XIX century. The article generalizes the experience of studying the theme of Khlystovshchina in Dostoevsky’s works, and persuasively argues that Dostoevsky’s perception of the phenomenon of Khlystovshchina is justified by his ideology of pochvennichestvo, which defines the scientific novelty of this research. It is concluded that the writer’s interests to the sect is explained by the fact that he saw a unique, soil phenomenon that represents man’s cognitive activity. The research underlines that the pursued by Dostoyevsky parallel between the doctrine of the Lord Radstock and Stundism (alien to a Russian person due to protestant origin), Tatarinova Society, and Khlystovshchina reflects a profound idea of the writer on spiritual crisis emerged due to disintegration of intelligentsia and people.
Linguo-specific lexis of Chinese language and problems of translation: on the example of 麻烦 máfan ‘trouble; disturb; worry’
Authors: Rukodelnikova Mariia , Nanii Lyudmila Olegovna , Kholkina Liliya Sergeevna
Published: May 2023

The subject of this research is the translation strategies of linguo-specific lexis of Chinese language. On the example of lexeme 麻烦 máfan ‘trouble; disturb; worry’, the author highlights the fundamental principles of describing linguo-specific words based on their grammatical functions, lexical compatibility, and stylistic connotations. The analysis of use of 麻烦 máfan determined a correlation between grammatical functions and stylistic connotations. Therefore, 麻烦 máfan is often used as an adjective in colloquial speech, while in the official language it is rather used as a noun. The study is conducted with application of the modern lexicographical methods, including work with dictionaries, corpus data analysis of the Chinese-English parallel corpora, as well as survey of native speakers. The scientific lies in the systematic application of extensive corpus material towards the analysis of linguo-specific lexis, which allows finding the appropriate translation equivalents. The research results lead to a number of recommendation on improvement of the Chinese-Russian dictionaries, and can valuable in the practice of teaching Chinese language.
Saj’ in Hadith: perception and functions
Authors: Rozov Vladimir Andreevich
Published: May 2023

The subject of this research is the rhymed and rhythmic prose (Saj’) in Hadith. The article is dedicated to the comparison of perception of rhymed and rhythmic prose by Companions of the Prophet Muhammad and subsequent Muslim tradition with the contained in Hadith records testifying to the use of Saj’ by Muhammad. The author cites an example of the rhetoric of Prophet Muhammad and his closest Companions articulated in rhymed and rhythmic prose, which were recorded in Hadith. These include sermons, speeches on religious topic, religious-legal decrees, and prayers. The scientific novelty consist in the statement that both, the medieval Arab-Muslim scholars and Orientalists traditionally pay lesser attention in their works to the rhymed and rhythmic prose than to poetry. Saj’ in Hadith remains one of the most insufficiently studied topics. The research demonstrated that despite the records on denial of Saj’ by Prophet Muhammad and his closest Companions, as well as distrusts of the medieval Arab-Muslim authors, Hadith has documented evidence of using the rhymed and rhythmic prose by Prophet Muhammad and his closest Companions. This can be explained by the established representations of religious discourse in the Early Islamic Arabia.

Authors: Dmitrieva Elizaveta Igorevna , Grubin Il'ya Valentinovich
Published: May 2023

The subject of this research is the different automotive and traffic terms in the English language from the perspective of their variance. The article explores the similarities and differences between the terms of the topic group “Automobile Transportation” in the British and American variants of the modern English language. Special attention is given to the etymology of the terminological units in questions. On the examined examples of terminology, it can be observed that some basic concepts carry national arrangement within the American and British tradition of formation of terminology. For selection of language material, this article utilizes such sources as The Oxford English Dictionary, The Dictionary of Transport and Logistics, Macmillan English Dictionary for Advanced Learners, Oxford Dictionary of Current English, Cambridge Dictionary Online, and Collins English Dictionary Online. The scientific novelty of this research is justified by the insufficient elucidation of the problem of territorial variance within the English language on the material of transportation terminology, which is a reflection of national perception of the surrounding world. The authors make a conclusion that despite the importance of the standardization and formalization processes, it is necessary to remember that terminology vastly reflects professional worldview.
The Metaphysical Analysis of the Chinese Taoism of Immortality: Case Study on Continuity and Changes of Ancient Excavated Jade Artifacts
Authors: Zhou Zhenhua
Published: May 2023

Taoist philosophy and metaphysics show an important role in ancient and modern Chinese society with its thinking about the value and meaning of life and has become an important resource for both traditional Chinese philosophy and modern. This article discusses the concept of immortality in Taoism from the point of view of metaphysics. The goal was to metaphysically analyze the symbolism of the immortality of jade artifacts found during archaeological excavations. The object of the study is the Taoist symbolism of the immortality of ancient jade artifacts, the subject is the continuity of Taoist symbols. The article is intended to expand knowledge in this direction. The author gives an idea of the metaphysical system of jade culture, at the same time considering Taoism from the point of view of metaphysics, as well as religion and an indispensable attribute of everyday life. Based on the analysis of 20 jade artifacts, the main characteristics of the symbols of Taoist immortality were revealed. The author comes to the conclusion that the theme of Taoist immortality, expressed in jade artifacts, accompanied the evolutionary process of inheritance, continuation, change and universal life and in a certain way influenced it. In different historical periods, people understand the Taoist thought of immortality in different ways, use different practices in different ways, regulate jade mining, so in different historical periods for Taoism, jade culture is a different form, reflecting the aesthetics of the characteristics of the ancient Chinese era and the pursuit of eternal thought and continuation of Taoism. The conclusions are discussed in three aspects: 1) the embodiment of the metaphysical worldview system of Taoism using the theme of "eternal life" and "immortality" in popular culture; 2) the embodiment of the metaphysical system of the ideology of jade culture; 3) takes into account the analysis of the continuation and change of the process of mutual integration of Taoist and jade culture. Thus, from the perspective of man and soul, the universality of the continuation of Taoism in jade can be clarified in order to fill the academic gap in this field.
The intonation of declarative questions in Northern British English varieties in spontaneous speech
Authors: Sola Alicia , Torregrosa Azor Jose
Published: May 2023

In this study, we analyse a sample of 76 utterances drawn from a corpus of spontaneous speech from the north of England. The selected statements present a declarative structure with different pragmatic functions (yes/no questions, echo questions, tag questions, and rhetorical questions). The objective of this study is to observe and describe the intonation of questions with a declarative structure in English from the north of England in spontaneous speech. Likewise, the pertinent bibliographic review is carried out for its subsequent discussion in view of the results obtained. The analysis is carried out in Praat, through the Melodic Analysis of Speech method (CANTERO, 2002) that allows the extraction of stylized, quantifiable and comparable melodic curves. As a result of this analysis, we obtain five different melodic that we can define as rising (21%), falling (50%), rising-falling (13%), final inflection with raised nucleus (4%), and declination and final rising inflection (12%).
Prosodic perceptive thresholds in Spanish: intensity and duration
Authors: Pálvölgyi Kata Baditzné
Published: May 2023

The following study aims at examining prosodic thresholds of perception for Spanish, parting from the algorithm of analysis offered by the Prosodic Analysis of Speech (PAS) model by Cantero (2019). The approach is based on defining the prosodic values for each syllable after a process of standardization, by relativizing the prosodic value associated with each syllable to that of the preceding one. As the perception threshold in the case of melody was defined as 10% for Spanish (FONT-ROTCHÉS; MATEO RUIZ, 2011), this research investigates, by the help of an anonymous perceptive test submitted to 30 native Spanish speakers, what prosodic relative values of intensity and duration change with respect to the previous syllable make a syllable perceived as prosodically prominent. The informants of the test had to decide whether in an invented Spanish word syllables with different range of increase in intensity or duration result in perceptibility as far as prosodic prominence is concerned, and whether these prosodic cues contribute to stress identification. As for the results, a 30% of increase in duration with respect to the previous syllable is already perceivable, but intensity growth of 5% is not, and neither of these thresholds trigger automatically stress identification. The results of the research can be used as a point of reference in speech synthesis programs.
La influencia del punto de articulación en las vocales del catalán
Authors: Rius-Escudé Agnès , Font-Rotchés Dolors
Published: May 2023

Numerosos estudios consideran que la influencia del contexto adyacente consonántico es uno de los factores que modifica los rasgos acústicos y la pronunciación del sonido vocálico. Para comprobarlo en un corpus de catalán en habla espontánea, hemos analizado 1590 vocales, producidas por 67 informantes, y hemos evaluado si el punto de articulación del sonido adyacente anterior y posterior influye en estas vocales para poder aplicar los resultados a la enseñanza-aprendizaje de esta lengua. Para el tratamiento de los datos, hemos extraído los valores acústicos de F1 y F2 de todos los sonidos vocálicos en Praat, se han relativizado los valores con el procedimiento de normalización intrínseca del hablante S-centroid (Watt y Fabricius, 2002), y hemos analizado la ANOVA y realizado comparaciones post hoc con el método Bonferroni. Los resultados que hemos obtenido se concretan en  que el punto de articulación del sonido adyacente anterior y posterior motiva pocos cambios acústicos en los sonidos vocálicos, aunque eran previsibles ante la variabilidad del habla espontánea; en que el fonema /ɛ/ es el que presenta más variabilidad,  /i/, /a/, /ᴐ/ y /u/, tienen poca, y /e/, /o/ y /ǝ/ no se ven afectados por el fenómeno; y, finalmente, en que el contexto bilabial, que motiva un descenso del F2 de la vocal es el más influyente. Constatamos, pues, que para la enseñanza-aprendizaje de los sonidos vocálicos del catalán, el punto de articulación de los sonidos adyacentes es un factor que motiva pocas variaciones en la pronunciación de las vocales y que no tiene mucho alcance en el desarrollo de actividades didácticas.

Authors: Pérez Mora Viviana Alejandra
Published: May 2023

Esta investigación tiene por objetivo describir el perfil melódico de enunciados interrogativos absolutos producidos por hablantes chilenos de las ciudades de Iquique y La Serena y comparar el comportamiento de sus curvas entonativas. Se consideraron alrededor de 14 horas de audio y se seleccionaron 98 enunciados, los que fueron analizados utilizando los postulados del Análisis Melódico del Habla (AMH) en su fase acústica. Dentro de los principales resultados se observó que las interrogativas absolutas del español de Chile presentan características propias y no tan similares a lo descrito para el español peninsular: normalmente no existe primer pico ni declinación, aparecen cuerpos que pueden ser ascendentes o planos (con pequeñas ondulaciones o zigzag) e inflexiones finales ascendentes, inflexiones finales ascendentes hasta el núcleo con un descenso posterior o circunflejas. Ya sea en el caso de enunciados con cuerpo y final ascendente o en aquellos con cuerpo plano e inflexión final ascendente, existe diversidad en cuando a los rangos de ascenso utilizados, aunque predominan aquellos abruptos, con un porcentaje igual o mayor al 101% de ascenso.

Published: May 2023

Introduction. Controversy exists regarding the use of NPWT for wound healing. Objective. This study assessed the effectiveness of NPWT compared with conventional treatment in the management of different wound types, including acute and chronic wounds. Materials and Methods. PubMed, Cochrane Central Register of Controlled Trials, Scopus, EMBASE, EBSCO, Ovid, and Web of Science were searched, from database inception up to October 2021, for relevant studies comparing NPWT with conventional treatment for wound healing. Primary outcomes included time to healing, wound healing rate, and duration of treatment. Secondary outcomes included adverse events, length of hospital stay, and 30-day mortality rate. Pooled analysis of the outcomes data is presented as SMD (95% CI) for continuous data and OR (95% CI) for dichotomous data. Results. Twenty-four studies (3064 patients) were included in the meta-analysis. NPWT was associated with shorter time to healing (SMD, −0.79; 95% CI, −1.22 to −0.37), shorter duration of treatment (SMD, −1.24; 95% CI, −1.92 to −0.56), and higher rate of wound healing (OR, 2.05; 95% CI, 1.49-2.83) compared with control. NPWT was also associated with a lower incidence of adverse events (OR, 0.42; 95% CI, 0.23-0.77) and a lower 30-day mortality rate (OR, 0.25; 95% CI, 0.12-0.56). There were no significant differences between NPWT and control regarding hospital stay (SMD, −0.52; 95% CI, −1.06 to 0.03). Conclusions. NPWT is seemingly associated with better wound healing outcomes compared with conventional therapy. However, the data should be interpreted with substantial caution given limitations such as high heterogeneity between studies and the small sample size of the included studies.
Novelty and the Structure of Design Landscapes: A Relational View of Online Innovation Communities
Authors:   ESSEC Business School, Kyriakou Harris , Nickerson Jeffrey ,   Stevens Institute of Technology, Majchrzak Ann ,   University of California
Published: May 2023

Design artifacts in online innovation communities are increasingly becoming a primary source of innovation for organizations. A distinguishing feature of such communities is that they are organized around design artifacts, not around people. The search for novel innovations thus equates to a search for novel designs. This is not a trivial problem since the novelty of a design is a function of its relationship to other designs, and this relationship changes as each design is added. These relations between artifacts affect both consumption and production. Moreover, these relations form a landscape whose structure affects the emergence of novelty. We find evidence for our theorizing using an analysis of over 35,000 Thingiverse design artifacts. This work identifies the differential effects of different forms of novelty, visual and verbal, on subsequent innovation, and identifies the differential effects of different degrees of structure in the landscape on novelty.

Entitlement has been identified as a potentially valuable employee characteristic in the prediction of computer abuse but has not been studied systematically in the IS domain. We introduce the construct of technological entitlement as the persistent sense of being more deserving of technological resources, uses, and privileges compared to other employees. Adapting a model of general entitlement to the work technology context, we theorize that technological entitlement predicts computer abuse and that this relationship is amplified by perceptions of technology restriction. After developing and validating a scale to measure technological entitlement, we conduct three studies with working adult samples to test our hypotheses. In Study 1 (n = 187), using a behavioral design, we find that technological entitlement predicts computer abuse behavior (beyond general entitlement) and that this relationship is stronger when employees perceive organizational restrictions on technology usage. We replicate these findings in Study 2 (n = 339) with an experiment. In Study 3 (n = 156), we manipulate the context of restrictiveness within our experimental vignette to establish the generalizability of our moderator. We discuss how technological entitlement helps explain existing inconsistencies in the effectiveness of deterrence measures as well as other theoretical and practical implications of our work.
Social Influence, Competition, and Free Riding: Examining Seller Interactions Within an Online Social Network
Authors:   China University of Geosciences (Beijing), Huang He , Huang Yan ,   Carnegie Mellon University, Yan Zhijun ,   Beijing Institute of Technology, Zhang Han ,   Georgia Institute of Technology
Published: May 2023

Online social networks are increasingly being used to conduct commercial activities, and many online social networking platforms allow users to sell products to their online connections. Although extensive research has been conducted on the interactions among buyers within a social network, interactions among sellers have rarely been explored. Using seller data from a company that sells on a major online social networking platform in China, we empirically examine how sellers’ efforts and sales performance are affected by the efforts and sales performance of other sellers they are connected to (i.e., their inviters and invitees) and the commissions they themselves have received. We find evidence for social influence and competition effects in the “inviter-to-invitee” direction and sellers’ free-riding behavior driven by the commissions they receive from their invitees’ sales. These results extend the social network literature that has largely focused on connected buyers (or users) to connected sellers and offer implications for social networking platforms to promote seller participation.
Repairing Integrity-Based Trust Violations in Ascription Disputes for Potential E-Commerce Customers
Authors:   Tongji University, Deng Honglin , Wang Weiquan ,   The Chinese University of Hong Kong, Lim Kai ,   The Hong Kong Polytechnic University
Published: May 2023

Trust violations of online sellers are widely reported in customer reviews and are often ascribed to the sellers’ lack of integrity. These reported violations reduce potential customers’ trust in the accused sellers, given the critical role of seller integrity in e-commerce. However, accused sellers and buyers often dispute the ascriptions of trust violations (e.g., sellers may argue that a violation is due to their lack of competence instead of their integrity). The trust repair literature has inadequately focused on effective strategies to repair reported integrity-based trust violations in ascription disputes. Drawing upon attribution theory and individuals’ cognitive sensemaking process regarding trust violations, we propose an account-based approach through re-ascription and stability attributions, enabling accused sellers to repair potential customers’ trust in them in the event of such disputes. We theorize the effectiveness of this approach by considering the contingent role of the accused seller’s reputation. The results of our laboratory experiments confirm the effectiveness of our approach in repairing potential customers’ trust for sellers with a high reputation but not for sellers with a low reputation. We further investigate the effectiveness of disclosing substantive amends (i.e., financial compensation) made by the accused seller to the victim as an alternative approach to repairing potential customers’ trust in sellers with a low reputation. The results reveal the significant effects of disclosing substantive amends on repairing potential customers’ trust in the seller, regardless of the seller’s reputation.

Although researchers have examined the role of dyadic dynamics (i.e., interactions between the acquirer and the target firm) in the success of acquisitions, little attention has been devoted to the role of information technology (IT). In this study, we extend this literature by examining how pre-acquisition IT distance (i.e., the difference between the enterprise IT systems of the two firms that reflects the system incompatibility and resulting costs of system integration) affects the acquirer’s post-acquisition performance. To measure IT distance, we used a word-embedding technique to map each firm’s IT systems portfolio to a low-dimensional embedding space and calculate the distance between the firms in that space. Using data on U.S. firms’ acquisition activities over seven years, we found that IT distance is negatively associated with the acquirer’s post-acquisition performance. Also, the adverse effect of IT distance is stronger for acquisitions motivated by operational synergies, compared to those seeking non-operational synergies. This finding supports our fundamental premise that IT distance disrupts post-acquisition synergy creation, and more so when the combined firm has a greater need for tight integration to create acquisition synergies. This research contributes to the merger and acquisition (M&A) literature in management and IS by introducing a novel concept of IT distance and by theorizing and empirically examining its performance implications in acquisitions. The findings of this study can inform practitioners on how to devise IT strategies in corporate acquisitions to mitigate IT risks and achieve greater post-acquisition performance.

We study the potential impact of the legal vulnerability created by ubiquitous information technology (IT) and provide insights into its unintended consequences in a typical healthcare screening context. Screening policies determine the level of care provision (i.e., whether to conduct a test) based on patient risk information. If IT shares risk information with physicians in the testing stage, follow-up decisions may be more accurate. Yet, physicians may also face heightened legal risk from increased information visibility. In this context, we examine the socially optimal screening (based on risk information) and follow-up policies (based on risk and test information). Litigation is generally associated with the overutilization of health care because of physicians’ defensive medicine practices. In contrast, we find that the strategic underprovisioning of health care through screening policies could be a consequence of information sharing in the presence of litigation concerns. The underprovisioning of health care is aggravated if the precision of risk information relative to that of the medical test increases or the physician becomes more self-interested and less patient oriented. However, limits on malpractice damages can alleviate the underprovisioning of health care.

The globalization of work raises important questions related to the employment of workers across geographies and how the complementarity or substitution of workers across country borders influences firm profitability. In particular, tension often exists regarding the substitution or complementarity of workers located outside the U.S. or within the U.S. for American firms. We investigate this question in the context of information technology (IT) professionals and assess how domestic and foreign IT professionals contribute to firm profit by utilizing a rare firm-level dataset with information on the locational composition of IT professionals within and outside the U.S. Exploiting a labor market supply-side exogenous shock induced by the American Competitiveness in the Twenty-First Century Act (AC21), which increased the availability of H-1B visas in the U.S. in 2001, we find that foreign IT professionals located offshore and American IT professionals located onshore complement each other in generating profits. Our model and empirical findings are important both for informing firm choices and for shaping and creating public policies that so far appear to have been informed more by emotion than by data and science.
Prototypische und essentialisierte Darstellung von Religionen bei Jugendlichen – eine explorative Studie nach dem Modell der Didaktischen Rekonstruktion
Authors: Schellenberg Urs , Saia Laura
Published: May 2023

Im Rahmen einer explorativen Vorstudie wurden an zwei Sekundarklassen der 8. Jahrgangsstufe Präkonzepte zum Thema Judentum erhoben. Die Schüler_innen verfügten über ein breites deklaratives Wissen, stellten das Judentum jedoch als in sich homogen und entlang eines stereotypen Bildes des Judentums dar. Nach dem Modell der Didaktischen Rekonstruktion wurde dann Unterricht gestaltet, um diese Konzepte durch solche der Pluralität und inneren Vielfalt zu erweitern. Die Resultate zeigen zum einen, wie schwer sich essentialisierte und prototypische Vorstellungen von Religion verändern lassen, zum anderen aber auch wesentliche Ansätze, wie dies angestrebt und erreicht werden kann.

Authors: Helbling Dominik
Published: May 2023

Religionsbezogene Objekte werden seit geraumer Zeit im Unterricht verwendet, wofür religionsdidaktische Ansätze wie die Symboldidaktik und der „A Gift to the Child“-Ansatz stehen, die auch in der religionskundlichen Didaktik Beachtung finden. Dieser Beitrag erörtert zunächst das Bildungspotenzial religionsbezogener Objekte. Danach analysiert er bestehende didaktischen Ansätze auf ihre Passung auf den religionskundlichen Unterricht und arbeitet ihren Entwicklungsbedarf heraus. Sodann wird der Forschungsansatz material religion als eine mögliche Ressource eingebracht, um die Didaktik religionsbezogener Objekte für den religionskundlichen Unterricht weiter zu entfalten.
Nucleation of Co and Ru Precursors on Silicon with Different Surface Terminations: Impact on Nucleation Delay
Authors: Liu Ji , Mullins Rita , Lu Hongliang , Wei Zhang David , Nolan Michael
Published: May 2023

The early transition metals Ruthenium (Ru) and Cobalt (Co) are of high interest as replacements for Cu in next generation interconnects. Plasma-enhanced atomic layer deposition (PE-ALD) is used to deposit metal thin films in high-aspect ratio structures of vias and trenches in nanoelectronic devices. At the initial stage of deposition, the surface reactions between the precursors and the starting substrate are vital to understand nucleation of the film and optimize the deposition process through minimising so-called nucleation delay in which film growth is only observed after tens to hundreds of ALD cycles. The reported incubation period (or nucleation delay) of Ru ranges from 10 ALD cycles to 500 ALD cycles and the growth-per-cycle (GPC) varies from report to report. No systematic studies on nucleation day of Co PE-ALD were found in the literature. In this study, we use first principles density functional theory (DFT) simulations to investigate the reactions between the precursors RuCp2 and CoCp2 with Si substrates that have different surface terminations to reveal the atomic scale reaction mechanism at the initial stages of metal nucleation. The substrates include (1) H:Si(100), (2) NHx-terminated Si(100), (3) H:SiNx/Si(100). Ligand exchange reaction via H transfer to form CpH on H:Si(100), NHx-terminated Si(100) and H:SiNx/Si(100) surfaces is simulated and shows that pre-treatment with N2/H2 plasma to yield an NHx-terminated Si surface from H:Si(100) can promote the ligand exchange reaction to eliminate Cp ligand for CoCp2. Our DFT results show that the surface reactivity of CoCp2 is highly dependent on substrate surface terminations, which explains why the reported incubation period and GPC vary from report to report. This difference in reactivity at different surface terminations may be useful for selective deposition. For Ru deposition, RuCp2 is not a useful precursor, showing highly endothermic ligand elimination reactions on all studied terminations.
Neural Network Potentials for Reactive Chemistry: CASPT2 Quality Potential Energy Surfaces for Bond Breaking
Authors: Hu Quin , Johannesen Andrew , Graham Daniel , Goodpaster Jason
Published: May 2023

Neural Network potentials are developed which accurately make and break bonds for use in molecular simulations. We report a neural network potential that can describe the potential energy surface for carbon-carbon bond dissociation with less than 1 kcal/mol error compared to complete active space second-order perturbation theory (CASPT2), and maintains this accuracy for both the minimum energy path and molecular dynamic calculations up to 2000K. We utilize a transfer learning algorithm to develop neural network potentials to generate potential energy surfaces; this method aims to use the minimum amount of CASPT2 data on small systems to train neural network potentials while maintaining excellent transferability to larger systems. First, we generate homolytic carbon-carbon bond dissociation data of small size alkanes with density functional theory (DFT) energies to train the potentials to accurately predict bond dissociation at the DFT level. Then, using transfer learning, we retrained the neural network potential to CASPT2 level of accuracy. We demonstrate that the neural network potential only requires bond dissociation data of a few small alkanes to accurately predict bond dissociation energy in larger alkanes. We then perform additional training on molecular dynamic simulations to refine our neural network potentials to obtain high accuracy for general use in molecular simulation. This training algorithm is generally applicable to any type of bond or any level of theory and will be useful for the generation of new reactive neural network potentials.
