CFM considera CAPs antiéticos para atendimento a doentes mentais
Authors: Cavalcanti Emmanuel Fortes Silveira
Published: June 2024

O primeiro Parecer de 2011 editado pelo Conselho Federal de Medicina (CFM) diz respeito a saúde mental. O documento considera antiéticas duas portarias, as de números 224/92 e 336/02, do Ministério da Saúde, que estabelecem normas e diretrizes para atendimento ambulatorial aos doentes mentais. Segundo o Parecer nº 1, as portarias estão em desacordo com a regência do CFM, pois não determina a permanência, em horário integral, do médico psiquiatra nos CAPs (Centro de Atendimento Psicossocial) Ille AD Ile AD IIl, que prevêem atendimento de acolhimento 24 horas, inclusive nos feriados e finais de semana. Para o vice-presidente do CFM e relator do parecer, Emmanuel Fortes, a palavra acolhimento desvirtua o real sentido do procedimento que é o de internar, conforme a Lei 10.216/01, gerando dubiedade e “vulnerabillizando a segurança da assistência aos pacientes e a prática do ato médico”. “Além da ausência do psiquiatra, os CAPs Ille AD Ile Ill estão internando os pacientes, ação que não está prevista nas portarias do Ministério da Saúde”, explicou Emmanuel Fortes. Por esta razão, o CFM já notificou a Coordenadoria de Saúde Mental, pedindo que sejam tomadas providências no sentido de garantir a presença de psiquiatras nos CAPs que prevêem atendimento 24 horas e recomendou aos Conselhos Regionais de Medicina (CRMs) que fiscalize os CAPs estaduais para verificar se aqueles que prevêem atendimento 24 horas possuem infraestrutura necessária para atendimento dos pacientes como ambulâncias para deslocamentos dos pacientes, medicação e médico psiquiatra no local, em atendimento ao horário de funcionamento dos centros. Também segundo o vice-presidente, ficará a critério dos CRMs estabelecer os prazos necessários para que as Secretarias Estaduais de Saúde adotem as medidas necessárias para manter os CAPs em funcionamento, de acordo com que estabelece portaria do Ministério Público. Depois de comunicado e estabelecidos os prazos, caso não seja adotada nenhuma providência, o CFM poderá procurar o Ministério Público e sugerir a interdição do local. Segundo o Ministério da Saúde, existem atualmente no país, 1.620 CAPs. Desse total, 761 são CAPs |, de atendimento rápido, para consultas e renovação de receitas, estabelecidos em cidades de até 70 mil habitantes. Os CAPs III, que prevê acolhimento dos pacientes e instalados em cidades com mais de 150 mil habitantes, são apenas 55 em todo o país, sendo que dez estados, Acre, Amapá, Roraima, Rondônia, Tocantins, Alagoas, Goiás, Minas Gerais, Espírito Santo, Rio Grande do Sul e o Distrito Federal não possuem CAPs III. Veja a seguir o Parecer nº 01 do CFM.

The Northeast of England in the era of the Wars of the Roses (using the example of the Paston family)
Authors: Portnov Aleksandr Aleksandrovich
Published: June 2024

The subject of the study is the participation of the English small-scale provincial nobility in the events of the Wars of the Roses (1455-1485) and their behavior patterns in the context of a dynastic conflict, using the example of the fate of John Paston from Norfolk County (northeast of England). Special attention is paid to how the relationship between the average nobleman and his neighbors was built, the circle of his acquaintances, the degree of involvement in national politics, personal conflicts and motives. Both the general patterns characteristic of the fate of most representatives of the privileged class of the XV century are considered, as well as the specifics that distinguish the region specifically studied and the personalities of interest to us in comparison with data from other counties (primarily the south-west of England). The main source is the fundamental family archive "Letters of the Pastors", which contains invaluable information on the English history of the period we are interested in. The research is based on the principles of historicism and scientific objectivity and is based on the problem-chronological principle. Analytical, comparative historical and dialectical methods are used in the analysis of historical sources. Due to the fact that the study is built around the biography of a particular person, the events of the epoch we are interested in are considered from the perspective of microhistory. Within the framework of the study, the working hypothesis developed by the author in other articles ("John Trevelyan and the Wars of the Roses", "English provincial Nobility and the Wars of the Roses", "The political struggle of the era of the Wars of the Roses in the light of English parliamentary legislation") on the evolution of the policy of the royal power in relation to the provincial nobility is being tested. At the initial stage of the Wars of the Roses, the Lancastrian party is the first to move to form the ranks of its supporters in the counties, which, using the example of Norfolk, leads to a conflict between John Paston and Lord Molanes, a prominent supporter of the Lancaster dynasty. The fact that Paston did not become an active Yorkist turned into difficulties for him at the next stage, when King Edward IV switched to a policy of reconciliation of warring factions, which is why the nobles, who remained neutral during the conflict, found themselves at enmity with both supporters of the Yorks and former Lancastrians reconciled with the new dynasty.
Phonetic features of the Hakka dialect of the Chinese language of Mei County
Authors: Skomorokha Eva , Chzhan Yui
Published: June 2024

This work is devoted to the study of phonetic features of the Hakka dialect of the Chinese language of Mei County. The material for this article was videos from the Chinese social network Bilibili. The object of the study is the Hakka dialect of the Mei County Chinese language. The subject of the study is linguistic features. The article discusses in detail the structure of the phonetic system of the dialect, namely the features of the tonal system, the system of initials and finals. Special attention is paid to the features that are uncharacteristic for Mandarin: the difference in the number of tones, the specificity of sounds, combinations of sounds that are absent in the generally accepted dialect. The phonetic characteristics presented in the article are illustrated by examples from the speech of the Hakka dialect speaking people of Mei County. In this article, the authors are of the opinion that dialects are an integral part of Chinese culture that requires special attention. The relevance of the work is justified by the tendency to preserve dialects, therefore, it is aimed at popularizing the Hakka dialect, a detailed study of its aspects. The study analyzed the following points: the current dialect situation in China, the role of dialects as a component of the cultural code of the country, the phonetic structure of the Hakka dialect of Mei County, its connection with the language of the Tang era. A special contribution to the research of the topic is the systematization of the currently existing information in the form of tables, as well as a description of the phonetic features of the dialect.
Reception of the Christian tradition of "cleansing" prayer in the lyrics of Julia Zhadovskaya
Authors: Zenevich Ekaterina Vasilievna
Published: June 2024

Due to the constant interest in the study of religious images and motifs in literary works, it becomes relevant to study the motifs contained in literary texts on religious subjects. One of the key features of the work of the poetess of the mid – 19th century Yu.V. Zhadovskaya (1824-1883) is an artistic reinterpretation of the Christian traditions of spiritual weeping and "cleansing" prayer. The subject of the study is the motif of prayer tears as an external sign of "cleansing prayer" in the lyrics of Yu.V. Zhadovskaya. The object of the research is the texts of religious and spiritual subjects of the first lifetime collection of poems "Temptation" (1845), "Calmly over me Again" (1846), "Monologue" (1846), "When reading the History of Peter the Great" (1846), the texts of the second lifetime collection of poems "Wonderful Minute!" (1847), "Night... Chu! into the shady Garden" (1846), "The Awakening of the Heart" (1848), "Who are my relatives" (1850) and unpublished texts "I remember that evening and quiet and beautiful", "Who loved and believed passionately", "The curly birches are noisy, noisy". To conduct the research, the method of historical and philological analysis, the biographical method, the comparative method, as well as the method of complex text analysis were used. A special contribution of the author to the study of the topic is the identification in the lyrics of Yu.V. Zhadovskaya of a group of poems of religious and spiritual themes, the lyrical event of which is focused on the Orthodox prayer tradition. The main conclusions of this study are the identification of the religious component of the author's worldview. Turning to the Christian tradition of spiritual purification allows, on the one hand, to define the basic framework of readers' expectations, and on the other hand, to violate the peculiar genre canon of "cleansing" prayer, embodying the poetess's special worldview, which consists in a "dual" worldview: the desire to find inner harmony and tranquility is combined with a tragic sense of God-abandonment. The artistic reinterpretation of the tradition of Orthodox prayer is primarily associated with the use of such an element of "cleansing" prayer as crying and tears in the lyrics. A special prayerful state and poetic communion with God in lyrical situations containing the motif of prayer tears are a sign of entering the "field of purity" for spiritual purification and prayer, as well as a sign of inner transformation. The novelty of the research lies in conducting a systematic analysis of the motive of prayer tears in religious and spiritual texts.
"Running bodies" under the lens of Michel Foucault
Authors: Kannykin Stanislav Vladimirovich
Published: June 2024

The article is devoted to the study of the formation of the "social body" of a runner athlete by means of anatomical and biopolitics, the concepts of which were developed by M. Foucault. The author solves such tasks as explication of the types and features of disciplinary practices used in the training of athletes specializing in running sports; analysis of the manifestations of resistance and transgression of runners; research of ethical self-transformation of athletes within the framework of Fucoldian "technologies of self"; identification of some urgent and emerging problems of running sports related to the relationship of power, control, body and knowledge. The paper also attempts to give applied importance to the Fucoldian interpretations of power relations in the interaction of "coach ‒ athlete" in order to problematize anatomical and political power and disciplinary practices used within its framework, which is important for the development of subjectivity and expanding the possibilities of realizing the potential of both an athlete and a coach. The research methodology is based on a conceptual analysis of M. Foucault's theoretical legacy and the reception of the French philosopher's ideas by Russian and Western scientists. The author identifies the main discourses that have the greatest impact on the training of athletes-runners (documents expressing state policy in the field of sports; texts of academic science; sports periodicals; popular science texts, as well as films, fiction, legends, etc.); analyzes the "disciplinary tools" of the sports training process (training plans exercises, specific organization of time and space, "hierarchical observation", "normalizing judgments", "recognition", "exam"); types of resistance and transgression of runners are revealed; the mechanism of work of athletes-runners on themselves within the framework of M. Foucault's "technologies of self" in order to improve their quality as an ethical subject is investigated; Fucoldian interpretations of some actual and potential problems of running sports are given, contributing to their deeper understanding (running addiction; strengthening control over runners using technical means; eugenics and neo-eugenics; cyborgization of athletes; doping as a component of anatomical and biopolitics; authoritarian coaching practices).
Economics of Analytics Services on a Marketplace Platform
Authors: Wang Zhe , Guo Hong , Liu Dengpan
Published: June 2024

Analytics services provided by marketplace platforms have become increasingly important for sellers seeking market insights. In this paper, we examine a scenario in which an analytics service plays a vital role in enhancing sellers’ understanding of market size and improving their decision-making. Using a game-theoretic model, we analyze the pricing strategies of the platform and the adoption strategies of sellers for the analytics service. Our study identifies two distinct effects of analytics services: the competition effect and the accuracy effect. Specifically, the competition effect manifests in opposing ways across different market scenarios, with a competition-intensifying effect in low-demand markets and a competition-weakening effect in high-demand markets. Consequently, sellers using an analytics service command lower prices in low-demand markets and higher prices in high-demand markets. More interestingly, our results reveal that offering an analytics service could potentially hurt the total market demand, subsequently impacting the platform’s revenue from the marketplace service and potentially leaving the platform worse off. Additionally, driven by both the accuracy and competition effects, adopting an analytics service may adversely affect seller profitability and consumer surplus without necessarily improving overall welfare. Moreover, the transaction fee for the marketplace service plays a crucial role in the interplay between the analytics and marketplace services. Specifically, in low-demand (high-demand) markets, as the transaction fee increases, platforms should consider reducing (increasing) the subscription fee to encourage more (fewer) sellers to adopt the analytics service, thereby enhancing overall market demand and increasing revenue from the marketplace service. Our findings also suggest that platforms should refrain from offering analytics services in high-demand markets when the transaction fee is relatively high. Furthermore, policymakers (sellers) should be mindful of the potential negative consequences associated with the adoption of analytics services in high-demand (low-demand) markets.
Dealing with Complexity in Design Science Research: A Methodology Using Design Echelons
Authors: Tuunanen Tuure , Winter Robert , vom Brocke Jan
Published: June 2024

Design science research (DSR) aims to generate knowledge about innovative solutions to real-world problems. Consequently, DSR needs to deal with the complexity related to problem and solution spaces involving sociotechnical phenomena that people perceive differently and are subject to constant change. This complexity poses challenges to sequential, process-based approaches—specifically, the existing DSR methodology. We designed a DSR methodology that extends existing approaches by adding a complementary organizing logic to address complexity. Based on the theory of hierarchical, multilevel systems, we suggest organizing DSR based on the concept of “echelons”—meaning decomposing DSR projects into smaller logically coherent self-contained parts—and suggest a set of five design echelons that imply a hierarchical organizing logic for DSR projects. The echeloned DSR (eDSR) methodology was developed in five iterations, involving seven design and evaluation episodes.
Deconstructing Technostress: A Configurational Approach to Explaining Job Burnout and Job Performance
Authors: Pflügner Katharina , Maier Christian , Thatcher Jason , Mattke Jens , Weitzel Tim
Published: June 2024

Understanding how technostressors lead to technostrain, such as high job burnout or low job performance, has become a core question in information systems (IS) research and practice. To unpack this relationship, we build on general systems theory to argue that the next step for technostress research is to go beyond examining the independent influences of technostressors and discuss how their interdependencies lead to technostrain. To illustrate our argument empirically, we use fuzzy-set qualitative comparative analysis (fsQCA) and identify four configurations of high- and low-intensity technostressors that lead to high job burnout and one that leads to low job performance. We show that three types of interdependencies among technostressors, i.e., complementarity, contingency, and substitution, form configurations that lead to technostrain. Within these configurations, high-intensity technostressors can mutually enhance their effects and low-intensity technostressors can buffer the impact of other high-intensity technostressors on technostrain. The results help to explain why organizational interventions that address independent technostressors may fail if they do not account for the interdependencies among technostressors. Our work provides evidence of the need to further develop theories that explain how and why interdependencies among technostressors lead to technostrain.
Understanding the Returns from Integrated Enterprise Systems: The Impacts of Agile and Phased Implementation Strategies
Authors: Aral Sinan , Brynjolfsson Erik , Gu Chris , Wang Hongchang , Wu D.J.
Published: June 2024

How do firms benefit from integrated enterprise systems (IES), and how does the IES implementation strategy influence the returns from IES? We investigated the implementation strategy that firms should follow to integrate multiple enterprise systems regarding the timing of adoption and the richness of modules. Borrowing theories from software development literature and enterprise system implementation literature, we developed two IES implementation strategies, i.e., the agile strategy (simple, quick, and flexible) and the phased strategy (rich, phased, and pre-determined). We collected a sample of 675 public firms from 1997 to 2004 at the module level, enabling us to distinguish enterprise resource planning (ERP) systems from customer relationship management (CRM) and supply chain management (SCM) systems. Our data contained the timing of purchase and “go-live” events of these system modules, helping us understand firms’ detailed implementation decisions. We found that IES returns depend on the choices of ERP and CRM/SCM module foundation, ERP-CRM/SCM sequential connection, and the continued adoption of ERP and CRM/SCM modules. Fewer ERP or CRM/SCM modules at CRM/SCM go-live events, a quicker connection between ERP and CRM/SCM go-live events, and the continued adoption of ERP or CRM/SCM modules all were found to enhance IES returns. Our findings show that the agile strategy leads to more returns from IES than the phased strategy and suggest that firms should integrate multiple enterprise systems by going live with advanced system modules quickly after going live with basic enterprise system modules and by continually adding new modules.
How the Locus of Uncertainty Shapes the Influence of CEO Long-term Compensation on Information Technology Capital Investments
Authors: Saldanha Terence , Andrade-Rojas Mariana , Kathuria Abhishek , Khuntia Jiban , Krishnan Mayuram
Published: June 2024

Firms must allocate resources effectively to cope with uncertainty, which can manifest as a disruption and an opportunity. Although information technology (IT) is a means to cope with uncertainty, chief executive officers (CEOs) may not always support IT investments due to the risky nature of IT, especially when facing uncertain conditions. While prior research suggests that CEO long-term compensation positively incentivizes IT investments, little is known about how different loci of uncertainty impact this relationship. To address this research gap, we study how firm-specific uncertainty and competitive uncertainty shape the influence of CEO long-term compensation on a firm’s IT capital investment. Drawing on agency theory and prospect theory, we develop two hypotheses. First, we hypothesize that firm-specific uncertainty and competitive uncertainty positively moderate the influence of CEO long-term compensation on firm IT capital investment. Second, we hypothesize that competitive uncertainty has a stronger positive moderating effect than firm-specific uncertainty on the influence of CEO long-term compensation on firm IT capital investment. Our analysis of secondary longitudinal data from 2000 to 2007 of 357 public firms in the United States supports our hypotheses. In exploratory analyses, we found that CEO long-term compensation results in a higher risk-oriented dominant logic in the firm, particularly in conditions of firm-specific uncertainty and competitive uncertainty, with competitive uncertainty having a stronger positive moderating effect. These findings uncover risk-oriented dominant logic as a theoretical mechanism that explains how CEO long-term compensation positively influences firm IT capital investment in uncertain conditions. We also conducted exploratory analyses using a different secondary dataset of 286 U.S. public firms from 2004 to 2019 to consider firm investments in transformative IT applications and found support for our theory. This finding triangulates our results across different time periods and different types of IT investments. This study contributes to theory and practice by providing a nuanced understanding of boundary conditions surrounding CEO long-term compensation, and decisions CEOs make vis-à-vis IT capital investments.
Data Commoning in the Life Sciences
Authors: Priego Laia , Wareham Jonathan
Published: June 2024

Datafication is driving organizations to invest in data commons, not only to share the costs of data generation, analysis, and curation but, more importantly, to realize synergies in precompetitive research collaborations where private and public motives interact (i.e., semicommons). The fanfare surrounding datafication often hails the sophisticated algorithms used to develop large quantities of data toward greater insight, naively assuming that more data equals better data. Yet for datafication in general and precompetitive research specifically, less attention is awarded to what actually constitutes data and evidence in the first place—that is, to its genesis, construction, and interpretation by heterogeneous scientific and commercial entities. We present the case of Open Targets, a precompetitive collaboration in the life sciences, where publicly funded research, nonprofit foundations, and for-profit pharma collaborate to generate and share data in genomics, proteomics, and bioinformatics. We theorize about the process of data commoning, a political activity in the semicommons where data are created, evidential value is assembled, and scientific meaning converges as data travels, or journeys, across creators, validators, and users. Our findings highlight the effects of relational dynamics and the political nature of data journeys: why these dynamics form, how they are manifested in a precompetitive semicommons, and what implications this can have for the mobility of data as a shared, public good.
Creation or Destruction? STEM OPT Extension and Employment of Information Technology Professionals
Authors: Guo Xue , Gong Jing , Pang Min-Seok
Published: June 2024

Information technology (IT) professionals play a critical role in digital transformation, innovation, and entrepreneurship, contributing to significant economic growth. The use of temporary work visas and related immigration policies has attracted significant controversy and policy debates in developed nations. On the one hand, foreign IT professionals can complement domestic IT professionals by bringing new skills and knowledge, which benefit domestic workers. On the other hand, foreign IT professionals may substitute for their domestic counterparts due to intensified labor-market competition. In this study, we focus on an extension in the Optional Practical Training (OPT) program in the U.S. for foreign science, technology, engineering, and mathematics (STEM) graduates from U.S. institutions. We explore the effects of the STEM OPT extension on the number and wage of domestic workers in STEM occupations and how these effects differ between IT and non-IT STEM occupations. We found that an increase in the supply of foreign STEM professionals from the OPT extension has boosted the employment of domestic workers in STEM occupations and that the effects are stronger for IT occupations. This study contributes to the information systems literature by demonstrating the unique effects of immigrant policies on IT occupations and provides significant implications for evidence-driven policy making.
Commercializing Social Media? How Showrooms on Social Media Fan Pages Influence Customer Behavior
Authors: Jung Jaehwuen , Wang Shuting (Ada) , Wattal Sunil
Published: June 2024

While marketing on social media fan pages has received widespread research attention, few studies have investigated the impact of adding a showroom to a social media fan page. Showrooms on social media fan pages are unique in that they can amplify the conflicts between businesses’ commercial purposes (selling) and customers’ expectations (socializing) on social media, making it unclear how they might influence customer behavior. In this study, we open this black box by using data from a leading fashion retailer. We found that adding a showroom to a fan page has both positive implications, in that it leads to more user engagement and purchases, and negative implications, in that it leads users to “unfollow” the retailer’s social media fan page. We further found that such impact is moderated by customer willingness to disclose private information. Specifically, the positive (negative) implication is significantly greater (smaller) for customers who are willing to disclose their private information to the retailer on social media. Mechanism-level analyses suggest that adding a showroom to a fan page can increase customer purchases both directly and indirectly by facilitating their engagement with the fan page and that customer willingness to disclose private information negatively moderates the mediation effect of user engagement on purchase behavior. In addition, results from an online experiment indicate that such showrooms can increase unfollowing by undermining users’ social perception of the fan page and raising users’ privacy concerns. Our findings suggest that even when firms see a significant increase in user purchase and activities after adding a showroom on their fan pages, they should carefully consider the potential risk of driving away customers and strategically target users who are less privacy sensitive.
Navigating the Digital Terrain of Prosocial Disclosures and Likability
Authors: Tan Xue (Jane) , Yan Lu (Lucy) , Pedraza-Martinez Alfonso
Published: June 2024

When people share their prosocial behavior on social media, they face a dilemma. By making prosocial disclosures, they risk being perceived as self-promoting or even selfish and thus less likable. By staying silent, they fail to spread awareness about prosocial activities they value. Drawing on attribution theory, we study the digital reaction of likes to the self-disclosure of prosocial activities that involve multiple stakeholders to understand the affordances and constraints of social media. Leveraging field data on a social networking site, we found that reporting a higher level of self-effort increases the digital reaction of likes. To our surprise, expressing gratitude for the sponsor’s efforts also increased likes for such self-disclosures. Through lab experiments that emulated this context, we dissected this paradox by separating the positive effect of expressing gratitude and the negative effect of sharing credit with other stakeholders on likes. Further, we underscore the salience of expressing gratitude, even when gratitude was extended to sponsors with bad reputations. Our study contributes to the design of a more humane digital world where individuals share and promote prosocial activities without compromising their likability and offers valuable insights for navigating the evolving landscape of social networking platforms.
Generativity and Profitability on B2B Innovation Platforms: A Simulation-based Theory Development
Authors: Haki Kazem , Tanriverdi Hüseyin , Safaei Dorsa , Schmid Marius , Aier Stephan , Winter Robert
Published: June 2024

Firms generate innovations to profit from market opportunities, which are newly identified customer needs not yet being met in the market. The rising complexity of market opportunities requires collaboration among multiple partner firms. However, this multipartner collaboration increases transaction and production costs when generating innovations. To address these challenges, incumbents build B2B innovation platforms with mechanisms to reduce partners’ transaction and production costs. We do not yet know if and when partners would choose to use the incumbent’s traditional service innovation model or the B2B innovation platform and how this choice would affect the generativity and profitability of innovations for the incumbent and the partners. We used agent-based modeling and simulation to develop a theory to address these questions. We found that the complexity of market opportunities interacts with the B2B innovation platform’s transaction and production mechanisms to jointly affect whether partners use the platform and when the incumbent and partners achieve generativity and profitability. When the complexity of market opportunities is low, partners use the traditional service innovation model. As complexity increases to medium or high levels, partners begin to use the B2B innovation platform mechanisms to address the transaction and production challenges presented by the complexity of market opportunities. However, there are limits to how much the platform mechanisms can address these challenges. The complexity of market opportunities inhibits the emergence of network effects on B2B innovation platforms and limits the generativity and profitability of platform partners. There are diminishing benefits of investing in the platform’s transaction and production mechanisms, and complexity affects whether the platform owner or the partners profit from innovations generated on the platform.
In-Consumption Information Cues and Online Video Consumption
Authors: Sim Jaeung , Choi Kyungmin , Han Sang Pil , Cho Daegon
Published: June 2024

Online video platforms such as YouTube feature visual cues on progress bars to spotlight standout segments of videos. These cues, designed to steer users toward intriguing content moments, raise questions about their overarching impact on video consumption patterns. In this study, we delve into in-consumption information cues (ICICs), indicators that depict fluctuating video quality in real time. Drawing from a natural experiment on a live streaming platform, we evaluate the effects of engagement graphs. These are visual timelines that emphasize moments favored by prior viewers in video-on-demand (VOD) content, which represent full replays of live stream sessions. Notably, these graphs are only accessible to iOS users, leaving Android users without access. Our results show that ICICs enhance the viewership of VODs and live streams. Moreover, viewers tend to spend more time immersed in live broadcasts, suggesting heightened content appeal. Yet, these engagement graphs do not prompt users to donate more virtual gifts, a vital income stream for streamers. Even with the introduction of ICICs, while there is a rise in video production, the inherent structure of live streams remained largely unchanged. We conclude by discussing the academic and managerial implications of these findings.
Digitization of Transaction Terms within TCE: Strong Smart Contract as a New Mode of Transaction Governance
Authors: Halaburda Hanna , Levina Natalia , Min Semi
Published: June 2024

We use transaction cost economics (TCE) to define the “digitization of transaction terms” shift parameter that describes the institutional changes associated with increased digitization in society. We then draw on legal scholarship to analyze how strong smart contracts, which refer to agreements with automatic execution and enforcement that are not reversible by courts, rely on a new level of digitization of transaction terms. Specifically, these contracts may rely on standard digital infrastructures such as blockchain systems that guarantee automatic execution and non-reversibility. Strong smart contracts represent a distinct mode of transaction governance compared to markets, hierarchies, or hybrids. This is because each classic governance mode is distinguished by how ex post adaptation is handled—through public courts, managerial fiat, or both. In contrast, strong smart contracts prevent ex post adaptation altogether. We propose that when strong smart contracts can be fully specified, they may dominate other governance modes based on certain trade-offs. These trade-offs include weighing the benefits of avoiding the holdup problem and lowering contract enforcement costs against the downsides of high ex ante specification costs and the elimination of flexibility to make ex post adjustments in a changing environment. Our discussion elaborates on which institutional conditions can further facilitate this institutional shift.
Lying for Viewers: Commingled Partisan Falsehoods Increase Viewing and Sharing of News Media
Authors: Seol Seyoung , Mejia Jorge , Dennis Alan
Published: June 2024

Is there an economic incentive for celebrities and well-known media firms to commingle falsehoods into news stories? We conducted five experiments, plus a field validation using secondary data. When presented by celebrities and well-known media firms, a commingled partisan falsehood in an otherwise true news story significantly increased viewing and sharing intentions among politically aligned viewers. The effect was weaker but significant when we replaced the celebrity with an unknown speaker and disappeared when both the celebrity and the well-known firm were replaced by unknowns. This effect was explained by confirmation bias and the viewer’s belief that the falsehood was true. In contrast, a false news story focusing on the same falsehood increased viewing and sharing intentions only when presented by unknowns, with viewers’ belief playing a limited role. The field study found a significantly positive relationship between a commingled partisan falsehood in videos of well-known media firms and actual viewership. We conclude that commingled partisan falsehoods provide a significant viewership increase for celebrities and well-known media firms, creating an economic incentive for lying and posing complex challenges in the fake news era. We discuss the challenges and opportunities in this area for policymakers and media firms.

Carica pubescens fruit juice improved superoxide dismutase, triglyceride and
high-density lipoprotein levels in type 2 diabetes mellitus Wistar rats
Authors: Rachmawati S.N. , Kusuma T.U. , Anjani G. , Muniroh M.
Published: June 2024

Insulin resistance and insulin deficiency in type 2 diabetes mellitus (T2DM) may increase
reactive oxygen species (ROS) production, which can exacerbate pancreatic β-cell. Insulin
resistance and insulin deficiency may also reduce lipoprotein lipase (LPL) activity,
increase triglycerides (TG) levels and decrease high-density lipoprotein (HDL) levels.
This condition could lead to cardiovascular complications. Flavonoids, such as rutin,
might be able to improve insulin resistance and increase insulin secretion in T2DM.
Carica pubescens is one of the typical Dieng fruits that has rutin. This study aimed to
investigate the effect of Carica pubescens fruit juice (CPJ) on superoxide dismutase
(SOD), TG, and HDL levels in high fat diet-streptozotocin-induced diabetic Wistar rats. A
total of twenty-five male Wistar rats were divided into five groups; untreated control
group (K-); untreated diabetic group (K+); the diabetic group was treated for 30 days with
4 mL/200 g BW of CPJ (X1); 8 mL/200 g BW of CPJ (X2); and 10 mg/200 g BW of rutin
(X3). This study revealed a significant increase in SOD and HDL levels and a significant
decrease in TG levels in groups X1, X2, and X3, compared to the K+ group (p < 0.05).
The increased level of SOD and HDL and the decreased level of TG between X2 and X3
were not significantly different. The effect of CPJ at 8 mL/200 g BW was similar to the
effect of rutin at 10 mg/200 g BW. These findings suggest the beneficial effects of CPJ on
SOD, TG, and HDL levels in type 2 diabetic Wistar rats.

The black cumin (Nigella sativa) seed oil has a long history of use for food ingredients.
The goal of this study is to figure out the nutritional and physicochemical properties of
two indigenous black cumin cultivars (locally known as "Kali Jira" and "Kalonji") seed
and oil. Additionally, the effects of extraction time and particle size on oil yield
generation was investigated. The values of moisture content, crude protein content, crude
fat, crude fiber, total ash, and carbohydrate of Kali Jira seed were 5.29%, 19.83%,
41.3%, 18.96%, 5.10%, and 9.52% whereas Kalonji had 5.43%, 19.95%, 40.3%, 14.28%,
4.35%, and 14.69%, respectively. In the Kali Jira and Kalonji types, the mineral analysis
revealed significant potassium levels (829.11 mg/100 g, 746.27 mg/100 g), followed by
phosphorus, calcium, sodium, iron and zinc. The minimum oil yield was 46.77% in the
Kalonji variety compared to Kali Jira, which had 49.57% after the extraction time of 2
hrs for 1.4-2.5 mm particle size. On the other hand, a maximum oil yield of 91.08% and
94.77% was found in Kalonji seed and Kali Jira seed, respectively, following a 6-hour
extraction time for 0.25-0.5 mm particle size. Characterization of extracted seed oil
(iodine value, saponification value, and acid value) indicated the abundance of
unsaturation in oil. FTIR analysis was used to investigate functional groups. According
to the findings of this study, black cumin and extracted oil are rich in nutrients and can be
used to treat lifestyle problems.

Due to the demand for high-quality water in people's daily lives, water quality has currently become a serious issue. There are numerous ways to enhance water. As more than a billion people on earth, in rural area water purification technologies have developed over the past few centuries to preserve public health. No one on this planet has access to pathogen-free, safe drinking water. India is among inhabited nations in the world where the poor cannot afford a portable, clean water source quality. Surface water is treated using a set of filters made of local materials. The effectiveness of single media and dual media was examined in the study of media to eliminate turbidity, color, and germs.Along to minimize this problem there are permanent solution needed. But now days in rural areas its big issue to purifying drinking water with simple technics. Also, government have an over burden of this issue. The government gives efforts for water purification scheme in rural areas. But such scheme includes the modern technics of water purification like a water treatment plant [WTP], or online pressure filter. Such modern technics government gives initial funds but after implementation of such technics there have a some frequently maintenance required. For this maintenance government cannot having suitable funds. That’s reason this all maintenance cost bear by the local government bodies like gram panchayat. But those bodies cannot have suitable income for implement of scheme in future, so such schemes are discontinued and a person drinks the contaminated water. Its big issue for their health so now days it’s important to develop the convenient and budget friendly technic for purification of drinking water.Due to this reason we are develop the water purification filter with the help of coconut shell and neem, in very pocket friendly budget
Collision-Damage Analysis of a Floating Offshore Wind Turbine Considering Ship-Collision Risk
Authors: Yu Young-Jae , Park Sang-Hyun , Cho Sang-Rai
Published: June 2024

As the number of offshore wind-power installations increases, collision accidents with vessels occur more frequently. This study investigates the risk of collision damage with operating vessels that may occur during the operation of an offshore wind turbine. The floater used in the collision study is a 15 MW UMaine VolturnUS-S (semi-submersible type), and the colliding ships are selected as multi-purpose vessels, service operation vessels, or anchor-handling tug ships based on their operational purpose. Collision analysis is performed using ABAQUS and substantiation is performed via a drop impact test. The collision analyses are conducted by varying the ship velocity, displacement, collision angle, and ship shape. By applying this numerical model, the extent of damage and deformation of the collision area is confirmed. The analysis results show that a vessel with a bulbous bow can cause flooding, depending on the collision conditions. For damage caused by collision, various collision angles must be considered based on the internal stiffener arrangement. Additionally, the floater can be flooded with relatively small collision energy when the colliding vessel has a bulbous bow.
