Using dynamic semantic structure of news flow to enhance financial forecasting: a twelve-year study on twitter news channels
Authors: Bodaghi Amirhosein , Zhu Jonathan J. H. 
Published: September 2024

AbstractThis research holds significance for advancing financial forecasting methodologies by shifting the focus from traditional sentiment analysis of individual tweets to exploring intricate semantic relationships within news tweets from top-followed news channels on Twitter. Addressing a notable research gap in financial forecasting, often dominated by sentiment analysis, our study endeavors to fill the void left by the underexplored intricate relationships within news entities and their dynamic semantic evolution. Motivated by the inherent challenges in predicting the random walk behavior of stock prices, we contend that incorporating longitudinal data derived from the semantic relationships between news entities can enhance the accuracy of stock market forecasts. The study pioneers a twelve-year exploration, encompassing data from 55 leading news channels on Twitter, boasting a collective following of 714 million users. The approach employs natural language processing (NLP) to extract two million unique entities, whose semantics are analyzed through complex network analysis, laying the foundation for the forecasting model. Finally, this research introduces a model linked to the dynamic semantic structure of news flow. The predictive model considers the impact of exogenous variables influenced by the evolving relationships among news entities. The results offer a proof of concept, highlighting the potential of utilizing dynamic semantic relationships among news entities for financial prediction. On average, the model demonstrates an improvement in accuracy of 40.3% across ten different stock price predictions. These findings are expounded through relevant theories, offering a theoretical foundation for observed patterns and indicating a promising direction for future research in this domain.
Belief in truthmaker semantics
Authors: Jago Mark 
Published: September 2024

AbstractStephen Yablo has argued that ascriptions of belief and knowledge are sensitive to subject matter and that theorising in such terms may help resolve philosophical questions about the semantics of such ascriptions. Truthmaker semantics offers a way of theorising about subject matters. My main aim in this paper is to investigate what a semantics for knowledge or belief ascriptions might look like within truthmaker semantics. I then discuss what the resulting account might have to say about the problem of logical omniscience, the nature of concepts, and rational belief.

AbstractThere is a lack of evidence for optimal management of patients with right colon cancers upon referral to the oncology care centre, following an inadequate index surgery elsewhere. A prospectively maintained database of patients with right colon cancers managed between 2013 and 2019 was screened to identify those patients who underwent index surgery in a non-oncological setup. They were managed with adjuvant chemotherapy followed by observation, with surgery being reserved for recurrent disease. Of the 155 patients identified after the screening, 97 were included in the study. They were stratified depending upon the number of lymph nodes harvested at primary surgery—Group A (less than 12 nodes) (n = 49), Group B (12 to 27 nodes) (n = 39) and Group C (28 and more nodes) (n = 9). Patients with lymph node metastases had inferior survival at 2 years than node-negative patients and this survival difference increased progressively from Group A towards Group C. Patients who had radiological locoregional residual disease upon restaging (at presentation) had significantly inferior survival. At the end of 2 years, overall survival and disease-free survival of the cohort were 71.5% and 45.8%, respectively. Fifty-eight patients had disease relapse, with peritoneal recurrence seen in 37 patients (63.8%). Of these, only 15.5% recurrences were surgically salvageable. Treatment of patients who have undergone inadequate index colectomy with chemotherapy alone has shown inferior survival outcomes with high rates of peritoneal relapse in comparison to historical cohorts. The treatment strategy for such patients needs to be revisited in a prospective study design.
The capital-on-capital cost in solvency II risk margin
Authors: Gambaro Anna Maria 
Published: September 2024

AbstractThis work contributes to the literature on time consistent valuation of insurance liabilities and to the ongoing discussion on revisions of risk margin (RM) calculation, by formally defining the concept of capital-on-capital cost. We describe the capital-on-capital as the amount required to cover unexpected variations in future regulatory capitals from the current time to liabilities maturity. That is, the capital-on-capital cost is the RM component dedicated to cover the risk of future RMs and not to cover variations of the best estimate of liabilities cash-flows. We mathematically formalize the capital-on-capital cost as the difference between two alternative time consistent liabilities valuation formula. The first is obtained through backward iteration of the one-period market-consistent valuation operator, by iterating the solvency capital requirement (SCR) risk measure. We propose a second alternative valuation formula for liabilities, based on a new time consistent dynamic formulation of the SCR risk measure, called additive-SCR (ASCR). The ASCR represents the expected total capital requirement from current time to liabilities maturity. We prove that the second valuation formula, based on ASCR, is time consistent, unless it is not based on iteration of the one-period SCR risk measure. Finally, we apply the proposed approach to a portfolio of long term equity linked life-insurance contracts. In particular, we estimate the capital-on-capital cost by calculating the difference between the two valuation formulas. Numerical results show that for liabilities with long maturities the capital-on-capital cost is a non negligible component of the RM.
The Presentation of Depression in Depressed Autistic Individuals: A Systematic Review
Authors: Hinze Emma , Paynter Jessica , Dargue Nicole , Adams Dawn 
Published: September 2024

AbstractThis systematic literature review examines the varied presentations of depression in depressed autistic individuals, including symptoms beyond DSM-5-TR criteria. A search of five databases (updated February 2024) identified 24 studies, encompassing 243 autistic individuals. Study quality varied, assessed using QuADS. The review was pre-registered with PROSPERO (CRD42022355322). Results were synthesised based on DSM-5-TR criteria and additional presentations, including who reported them. Findings showed 91.66% of studies reported presentations beyond DSM-5-TR criteria. Additionally, some DSM-5-TR symptoms may present differently in autistic individuals. Variations in depressive signs were noted across self-reports, informant-reports, interviews, and questionnaires. Clarifying whether these additional presentations are autism-specific, arise from the intersection of autism and depression, or manifestations of a depressive disorder is necessary for refining diagnostic tools.
Clinical Clerkship With or Without Scheduled Patient Consultations: Does It Make a Difference to Medical Students’ Experiences of Learning?

Published: September 2024

Abstract
Background
Becoming a medical expert involves leadership and professionalism, which are critical skills to learn in medical education. However, a gap exists in understanding how didactic variations in the organisation of clinical clerkships impact medical students’ opportunities to develop these skills. This study explored how clinical clerkships with or without scheduled patient consultations affect medical students’ experiences of learning leadership and professional behaviour.

Materials and Methods
We conducted a qualitative, quasi-experimental study. Data were gathered through 11 end-of-clerkship focus group interviews with 87 fifth-year medical students who participated in one of two 8-week clerkships at a surgical department: a clerkship with a mentor physician or a clerkship with scheduled patient consultations in combination with a mentor physician. Using a constructivist lens, we analysed the focus group interview transcripts and applied grounded theory principles to the iterative coding process.

Results
The analyses resulted in a descriptive framework displaying nine themes. Each theme was described as a spectrum of meanings that offers a nuanced understanding of how didactic variations in the organisation of clerkship impact how students ascribed meaning to the learning experiences in undergraduate medical education, focusing on learning leadership and professional behaviour.

Discussion
This study investigates differences in student learning experiences when participating in a clerkship with or without scheduled patient consultation and, therefore, adds new insight into the need for a balanced, thoughtful, and didactic approach to medical education that considers both clinical exposure and co-regulated learning.

Published: September 2024

AbstractA parallel, multi-campus anatomy curriculum was developed that could be delivered with or without body donor cadaveric teaching resources. This blended program includes asynchronous lectures, e-Learning modules, formative self-assessment, independent study, and synchronous hands-on practical sessions. Practical sessions at the metropolitan campus utilise professionally prepared body donor cadaveric teaching resources, whereas rural campus practical sessions use a combination of non-cadaveric resources such as 3D models (physical and digital) and interactive multimedia to achieve identical learning outcomes. Here, we discuss the specific features of the practical sessions delivered in this novel cross-campus curriculum, with a focus on the non-cadaveric teaching resources deployed.

Published: September 2024

AbstractFeelings of affection (i.e., fondness and intense positive regard) are a hallmark of close relationships. Existing studies have often examined affection as a trait or behavior, but rarely as an emotional experience in social interactions. In two dyadic observational interaction studies (total N = 314 individuals), 49 US-based married couples (age range: 21–65) and 108 friendship dyads (age range: 15–26) engaged in two naturalistic 10-min conversations about (a) a topic of disagreement (conflict conversation) and (b) something they enjoyed doing together (pleasant conversation) and reported on their subjective emotional experiences (e.g., affection, using an emotion checklist following each conversation) and relationship satisfaction. Conversation transcripts were analyzed using natural language analysis. Results showed that experiences of affection were most strongly associated with experiences of compassion, amusement, and excitement, as well as with less anger, and were unrelated to most other negative emotions. Natural language analysis further showed that greater positive (but not negative) emotional tone was associated with greater affection (especially among friends in the pleasant conversations). Levels of affection were consistently higher in pleasant versus conflict conversations and similar across marital versus friendship interactions. Finally, experiences of affection were associated with greater relationship satisfaction for friends across conversations and for spouses (women) in the pleasant conversation. These findings contribute to our understanding of affection as a foundational emotional experience in close relationships and highlight avenues for future research.
Care robot literacy: integrating AI ethics and technological literacy in contemporary healthcare
Authors: Turja Tuuli , Kork Anna-Aurora , Ilomäki Sakari , Hellstrand Ingvil , Koistinen Aino-Kaisa 
Published: September 2024

AbstractHealthcare work is guided by care ethics, and any technological changes, including the use of robots and artificial intelligence (AI), must comply with existing norms, values and work practices. By bridging technological literacy and AI ethics, this study provides a nuanced definition and an integrative conceptualization of care robot literacy (CRL) for contemporary care work. Robotized care tasks require new orientation and qualifications on the part of employees. CRL is considered as one of these new demands, which requires practitioners to have the resources, skills and understanding necessary to work with robots. This study builds on sociotechnical approach of literacy by highlighting a dynamic relationship of care robotization in which successful human–technology interaction relies on exchanges between the technological and the social. Our findings from directed content analysis and theoretical synthesis of in-demand technological literacy and AI ethics in care work emphasize competencies and situational awareness regarding both using the robot and communicating about the care robot. The initial conceptualization of CRL provides a conceptual framework for future studies, implementation and product development of care robots, drastically differing from studying, implementing and developing robots in general. In searching for technologically sound and ethically compliant solutions, the study advocates for the future significance of context-specific CRL as valuable addition to the terminology of ethical AI in healthcare.

Published: September 2024

AbstractThis study presented a numerical simulation of heat transfer characteristics in a microchannel evaporator for a transcritical CO2 air conditioning system, and the simulated results have been validated by the experimental data. The evaporator consists of 6 passes with 29 flat tubes. Each flat tube has 10 microchannels having a 1.2 × 0.6 mm cross-section. The two-phase flow was simulated in the range of evaporation temperatures from 5 to 15 °C; the mass flow rates of 24.16, 30, and 34.96 g/s; and inlet vapor qualities of 0.5, 0.61, and 0.75, respectively. The results show that the two-phase flow with the evaporative temperature at the inlet of 5, 10, and 15 °C became superheated at the 3rd, the 4th, and the 5th pass, respectively. At the evaporation temperature of 15 °C, the heat transfer coefficient decreases from 8.1 to 3.6 kW/m2 K as the vapor quality increases from 0.75 to 1. With the mass flow rate of 30 g/s, in the tube length range from 0 to 1.1 m, the heat flux achieved around 1.55 kW/m2. The numerical cooling capacity gets the maximum value of 2.85 kW at the evaporative temperature of 10 °C. The numerical results are in good agreement with those obtained from the experimental results and the other published results, with a deviation of less than 10%.
Love actually: a thematic review of teacher passion for the subject
Authors: Jons Lotta 
Published: September 2024

AbstractWhat does it mean to feel passionately for the subject one teaches? What does such a passion entail for those involved in the teaching–learning situation? This study focuses on the teacher’s passion for their subject. Nine scholarly texts were reviewed, which allowed for four distinct notions of passion to be discerned: i.e., romantic, friendly, erotic, and divine love. Findings showed also combinations of these notions as well as ontological variations. Inductively created themes revealed that the foundations of these different notions of passion ranged from love of the Truth and the Good to a calling from the subject, and that the character of these notions ranged from them being about intellectual and emotional allure to being about their being disclosed and brought to fulfilment. It also revealed what the different notions of love entailed for the teacher, the student, and the subject itself: for the teacher—from a demand to seek the good in the subject to a requirement to perceive the subject as a voice, the subject in turn making their life meaningful; for the student—from becoming part of the community of “we who love subject X” to a “homecoming of self-hood”; and for the subject itself—from beginning to reveal itself to holding teachers and students accountable. The usefulness of the findings for teacher education and research on teacher–student relations is discussed.

Published: September 2024

Abstract

Objective:
Although preventable through established infection control practices, catheter-associated urinary tract infections (CAUTIs) remain prevalent in acute-care settings. Our goal was to improve the CAUTI rates through multiple hospitals through implementing sustainable practices, including enhancing communication, provider engagement, accountability, and transparency in reporting to achieve long-term improvements.

Design:
Quality improvement with multiple levels of interventions

Setting:
A health system in northern Ohio with 21 affiliated hospitals across 16 counties.

Patients:
Adult patients admitted to the hospital between June 2020 and June 2023.

Methods:
A broad set of quality improvement (QI) strategies was developed by an interdisciplinary team and guided by the Fractal Management System framework to ensure accountability, communication, and alignment across teams and facilities. Key drivers were indwelling urinary catheter (IUC) alternatives, insertion, maintenance, removal, and smart diagnostics. The main outcome measures were standardized infection ratios (SIR) and standardized utilization ratio (SUR), comparing period 1 (P1, June 2020 to December 2021) and period 2 (P2, January 2022 to June 2023).

Results:
Enhanced communication and management played crucial roles in minimizing IUC placement. Updated policies and protocols, coupled with clear guidelines and decision support tools, facilitated effective urinary management. Performance tracking and visual management boards provided real-time insights, while collaborative efforts, including staff huddles and multidisciplinary teamwork, ensured consistent adherence to best practices.

Conclusions:
A systemwide QI initiative focused on enhanced communication, management, and collaboration contributed to improved SIR and reduced CAUTI rates across multiple hospitals, highlighting the impact of strong communication and proactive management in healthcare settings.
Mitigating gender inequality in women's voices: the role of normative gender-egalitarian messages
Authors: Takahashi Ryo 
Published: September 2024

Abstract
This study empirically examines gender inequality in tolerance for women's opinions and identifies how the provision of normative gender-egalitarian message can mitigate this inequality by conducting online randomized experiments in Japan. In this experiment, I asked the participants to evaluate the agreement score for 10 anonymous statements and implemented two types of random interventions: disclosing the gender of the statement poster and providing normative statement for gender equality. The results of both cross-sectional and panel data analyses showed that people significantly reduced the agreement score for women's opinions compared with men's and non-gender disclosure opinions. Meanwhile, the negative impact of female gender disclosure was neutralized when participants were provided with a normative message.
Envisioning the Beloved Community: Racial Justice, Property Law, and the Social Mortgage
Authors: Carmella Angela C. 
Published: September 2024

Abstract
The Reverend Dr. Martin Luther King, Jr. was concerned about both poverty and race, inextricably linked because of the long and brutal history of racial injustice in housing, employment, and education. What Dr. King called the beloved community reflected a vision of a world built on peace, human dignity, and shared material abundance for all people. To explore this linkage of poverty and race, I employ two related Christian theological concepts: the universal destiny of the goods of the earth and the social mortgage that encumbers all private property to ensure the equitable provision of those goods to all and for all generations. I analyze the ways in which the universal destiny of goods can be mediated through U.S. property law by structuring the ownership and use of land and buildings within the context of social obligation. But while the law has the capacity to ensure ownership, security, and infrastructure for all, U.S. society has failed to make the necessary payments on the social mortgage that would create this reality—a failure due primarily to severe racial and economic injustices, both historical and contemporary. Yet there is hope: I present examples that offer glimpses of the beloved community.
Pork Barrel and Identity Politics: Explaining a Minority Party’s Electoral Success in Lithuania
Authors: Agarin Timofey , Dambrauskas Karolis 
Published: September 2024

Abstract
Our article describes the lifecycle of Lithuania’s Electoral Action of Poles–Christian Families Alliance (LLRA-KŠS) party that has been a part of country’s political landscape for near 30 years. Despite its seemingly ethnic program, the party has a poor track record for delivering on its electoral promises. Yet, it has been continuously supported by the majority of Polish-speakers in Lithuania. The background of the nationalizing state, which encourages the party elites to conflate substantive representation with the signposting of ethnic identity in party politics, offers one of the reasons for the LLRA-KŠS’s electoral success. Although the party effectively consolidated its regional electorate, it came to control service delivery to their ethnic constituency by engaging in pork barrel politics. Poor performance in recent national and municipal elections put this strategy to bond with its voters into question, casting doubt on the LLRA-KŠS’s ability to survive as an ethnic party in the long term.
