Published: January 2025

ABSTRACT

Introduction
The purpose of this study was to examine the effects of reallocating time spent in weekday sedentary behavior (SED) to sleep duration, walking activity, or moderate-to-vigorous physical activity (MVPA) on body mass index (BMI) in college students using an isotemporal substitution model.

Methods
Self-reported BMI (height and weight), sleep duration, weekday SED, walking activity, and MVPA were obtained using the Pittsburgh Sleep Quality Index and International Physical Activity Questionnaire.

Results
Among participants (n = 1533, 20.1 ± 1.5 yr old), sleep duration (r = −0.069) and MVPA (r = −0.069) were inversely associated with BMI (P < 0.01). Reallocating 60 min of weekday SED to sleep duration (B = −0.277; 95% confidence interval (CI): −0.462 to −0.092) or MVPA (B = −0.386; 95% CI: −0.626 to −0.147) was associated with lower BMI, with stronger associations observed among students with overweight/obesity.

Conclusion
Greater time spent in sleep and MVPA was associated with lower BMI, especially among overweight/obese college students. Lifestyle modifications should include reducing SED and increasing sleep and physical activity because these factors are associated with lower BMI.

Published: January 2025

We investigate whether and to what extent financial markets value and respond to operations management (OM)-related information in quarterly earnings calls directed toward financial market participants. We develop and use a novel construct called “stated OM focus” (SOMF) to mine the incidence of and emphasis on OM information in the quarterly earnings conference calls for a large cross-section of firms (S&P 1500) over a time frame of 15 years. We empirically establish the value-relevance of OM information as well as summarize and capture both explanatory and predictive aspects of the OM function’s contribution to firm value. We show that OM-related information disclosed by firms systematically, significantly, positively, and persistently affects abnormal stock returns after controlling for known covariates and controls (financial metrics, standard OM metrics, firm and time effects, and lexical-structure related) and after accounting for earnings surprise. Furthermore, we find evidence that firms’ stated OM focus bears significant predictive power in the short term. Long-short portfolios, created using a sorting signal derived solely from stated OM-focus information, predict future abnormal returns consistently over one, two and three months forward from the earnings call event. We show that the OM information metric is reliable and bears internal, external, and predictive validity. These findings offer useful implications for firms, financial market participants, and OM function stakeholders. This paper was accepted by Jayashankar Swaminathan, operations management.

Mind maps as multimodal and multilingual literacy practices in Chinese private universities
Authors: Shi Liping 
Published: January 2025

Abstract
This study explores the integration of multimodal teaching, translanguaging, and dialogic pedagogy to improve English literacy among junior students in a Chinese private university. In the context of globalization, proficiency in English is essential for these students, yet many face challenges that hinder their literacy development. This research examines how multimodal mind maps, as tools for translanguaging and multimodal learning, reveal student perspectives on language learning and literacy development in Chinese private universities. The study offers insights with significant potential for shaping educational practices and curriculum design in Chinese private universities (Canagarajah, Suresh. 2012. Translingual practice: Global Englishes and cosmopolitan relations. New York: Routledge). By strategically implementing multimodal teaching techniques, the research introduces innovative strategies to enhance English literacy (García, Ofelia & Li Wei. 2014. Translanguaging: Language, Bilingualism and education. Palgrave Macmillan; Jewitt, Carey & Gunther Kress. 2010. Multimodality, literacy and school English. In D. Wyse, R. Andrews & J. Hoffman (eds.), The Routledge international handbook of English, language and literacy teaching, 342–352. London: Routledge; Vygotsky, Lev S. 1978. Mind in society: The development of higher psychological processes. Cambridge, MA: Harvard University Press). The findings highlight the interplay between linguistic strategies, instructional methods, and student perspectives, offering effective pedagogical interventions that prioritize multimodal engagement. By bridging theory and practice (Canagarajah, Suresh. 2012. Translingual practice: Global Englishes and cosmopolitan relations. New York: Routledge), this research provides actionable insights that address the literacy challenges and aspirations of junior students. Using a multimodal teaching approach (García, Ofelia & Li Wei. 2014. Translanguaging: Language, Bilingualism and education. Palgrave Macmillan), this study not only demonstrates how diverse modes of communication strengthen students English skills and foster their confidence but also addresses the development of their identities as competent members of an English academic community. Drawing on Norton’s (Norton, Bonny. 2013. Identity and Language learning: Extending the conversation. 2nd edn. Bristol: Multilingual Matters) work on identity and investment in language learning, this research underscores the importance of identity construction in the language learning process. It shows how students, through multimodal engagement, can assert their identities and claim the right to participate in academic communities, thereby preparing them for success in a globally interconnected society.
Study of Seepage Characteristics and Statistical Damage Constitutive Model of Calcareous Mudstone under Different Fluid Pressures

Published: January 2025

Abstract
The ground stress and water pressure together impact the underground water diversion tunnels in plateau regions, which poses a serious threat to the stability of the surrounding rocks and the safety of engineering structures. Typically, the surrounding rock is calcareous mudstone, which is susceptible to weakening by water. This paper presents an experimental study of calcareous mudstone’s mechanical behavior and permeability characteristics under different fluid pressures in a soft rock tunnel of the Central Yunnan Water Diversion Project (CYWDP) in China. The test results show that the fluid pressure affects the calcareous mudstone’s strength and permeability characteristics, leading to its failure and deformation. The fluid pressure promotes the development of internal microcracks, reduces peak stress and damage stress, and influences failure modes. The evolution of permeability with strain is strongly related to the development of microcracks. Based on the statistical damage theory, a rock damage constitutive model considering fluid pressure and porosity is proposed, and experimental data are used to validate its effectiveness. The research results can be used for understanding the mechanical behavior and constitutive model of hydro-mechanical coupling in soft rock underground projects.

Published: January 2025

AbstractBackground and aimsThe recent resurgence of psychedelic research has led to increased interest in extra-pharmacological factors shaping drug effects (set and setting). Habitually discussed in the context of psychedelic therapy, the relevance of set and setting to determining the outcome of non-psychedelic psychiatric interventions receives strong theoretical and empirical support in the literature. Unfortunately, there has been little research on the subject. The current study addresses this lacuna and investigates the potential of using non-pharmacological interventions to improve the outcomes of psychiatric care including safety, satisfaction, efficacy, and non-habituation.Methods110 participants (patients prescribed with psychiatric medication) took part in workshops focused on 1) Relaxation (Anxiolytics) 2) [n = 70] Focus (Stimulant ADHD Medication) [n = 40]. Workshops included a) an educational section designed to increase participants' understanding of their medical conditions and prescribed medications b) an experiential section that included the guided, mindful ingestion of the prescribed drug in a supportive setting including reinforcing cues and the practice of non-pharmacological techniques for coping with underlying medical conditions.ResultsSurvey questionnaires (n = 33) indicated a significant improvement in participants' understanding of their medical conditions and the properties of their prescribed medication. Semi-structured interviews demonstrated a strong interest in the idea of mindful use of medication, benefit from the communal setting of ingestion, as well as recurring themes of greater satisfaction with- and improved ability to derive benefit from the use of prescribed drug.ConclusionsThe results of this pilot study demonstrate the impressive potential of providing patients with extra-pharmacological tools to improve the outcomes of prescription drug use and supports the need for further study.

Silver nanowires (AgNWs) have attracted significant research interest due to their potential in conductive films, flexible electronics, electromagnetic interference shielding, sensors, energy storage, and integration into wearable devices. This study developed conductive inks with tailored viscosities for fabricating films with stable electrical resistance. The formulations were optimized for screen printing, inkjet printing, and direct writing by doping AgNWs into carbon paste dispersed in N,N-dimethylformamide. Flexible conductive circuits were printed on silk film substrates, and their electrical resistance was evaluated by varying AgNW concentration and the number of printed layers. Cyclic bending and energizing heating experiments were conducted to assess durability. The results demonstrated that doping with AgNWs significantly reduced film resistivity, with a concentration of 30 mg/ml being optimal for screen printing, inkjet, and direct printing. Screen-printed films exhibited the lowest resistivity, decreasing from 1.2 × 10−4 to 3.5 × 10−5 Ω·cm with increasing AgNWs concentration from 5 to 30 mg/ml. The resistivity of inkjet-printed and direct-written films at 30 mg/ml AgNWs was 5.8 × 10−5 and 7.2 × 10−5 Ω·cm, respectively. Increasing the number of printed layers from one to seven further reduced resistivity by 62% for screen printing, 58% for inkjet printing, and 55% for direct writing. Cyclic bending tests showed that after 1000 bending cycles, the resistance increased by 18% for screen-printed films, 25% for inkjet-printed films, and 30% for direct-written films. Screen-printed films exhibited the lowest resistivity and longest service life, highlighting their potential for diverse applications in flexible electronics and the broader electronics industry.

Published: January 2025

: India’s elderly population faces growing cancer incidences, with unique challenges rooted in cultural, socioeconomic, and healthcare disparities. Limited health literacy, delayed medical intervention, gender biases, and inadequate healthcare infrastructure, particularly in rural areas, worsen the issue. Social stigma and psychological barriers further hinder prompt cancer diagnosis and treatment, leaving many elderly patients vulnerable to advanced-stage diagnoses.:This study aims to identify and analyse the key challenges faced by elderly cancer patients in India, including cultural attitudes, access to healthcare, financial constraints, and psychosocial impacts. Additionally, the goal is to propose strategies for improving cancer care, prevention, and support for this demographic.A mixed-methods approach was utilised, incorporating quantitative and qualitative analyses to assess challenges in elderly cancer care in India. This review synthesises data from studies published between 2018 and 2023, using information from national cancer registries, Indian Council of Medical Research (ICMR) reports, and peer-reviewed literature. Studies included addressed socio-cultural, economic, and psychological barriers in elderly cancer care across India, focusing on gaps in knowledge and intervention strategies. The analysis revealed that 60% of cancers and 70% of cancer-related deaths occur in individuals aged 65 and above. Low health literacy, delayed diagnosis, and financial constraints were identified as the primary barriers. Significant treatment aversion was noted, with 58% of elderly patients perceiving chemotherapy as harmful. Rural areas lacked adequate healthcare facilities, contributing to delayed diagnosis and treatment. Psychosocial issues, including depression and anxiety, were prevalent and often aggravated by social isolation and stigma.: Addressing these issues requires a multifaceted approach, including policy interventions to expand healthcare access in rural areas, enhance health literacy, and provide financial support for elderly patients. Collaborative efforts involving government, non-governmental organisations, and community leaders are essential to improve early diagnosis, treatment accessibility, and quality of life for elderly cancer patients in India.
Transforming cancer care: The vital role of palliative support
Authors: Mahani Anmol , Singh Taranjeet 
Published: January 2025

Cancer remains a leading cause of mortality globally, with the increasing cancer burden in both developed and developing countries, including India. Palliative care, which focuses on alleviating the symptoms and improving the quality of life for patients, plays a crucial role in cancer management. Despite its significance, the integration of palliative care into cancer treatment in India faces numerous challenges, particularly in rural areas where healthcare access is limited.This study aims to examine the role of palliative care in the comprehensive management of cancer patients, particularly in India. It seeks to explore the specific needs of elderly cancer patients, assess common barriers to effective palliative care, and evaluate the impact of home-based palliative care models in improving patient outcomes.Data was collected through a combination of literature review and patient surveys, focusing on cancer care and palliative needs in India. Assessment tools such as the Edmonton Symptom Assessment Scale (ESAS) and the Palliative Performance Scale (PPS) were employed to evaluate symptom burden and prognosis. The study also analysed operational strategies for implementing home-based palliative care and the role of multidisciplinary teams in enhancing care delivery.The study found that palliative care significantly improves the quality of life for cancer patients by addressing their physical, emotional, and social needs. Home-based palliative care emerged as an effective model, particularly for patients in rural areas, where access to specialised healthcare is limited. Challenges such as a lack of trained personnel, inadequate awareness of palliative care, and logistical difficulties in rural settings were highlighted. The use of assessment tools such as ESAS and PPS helped in better symptom management and tailoring care to individual needs.Palliative care plays a critical role in the holistic management of cancer patients, particularly in resource-limited settings like India. The study underscores the need for more widespread integration of palliative care into the healthcare system, with a focus on home-based care and interdisciplinary collaboration. Increased awareness, training, and policy support are essential for improving access to and the quality of palliative care services, enhancing the well-being of cancer patients across the country.

Abstract

Purpose: In healthy participants, T2 superficial localized low intensity (T2-SLL) similar to superficial siderosis has been observed in the brainstem. This study aimed to determine the incidence and causes of T2-SLL.
Methods: To determine the incidence, T2-weighted imaging (T2WI) was performed on 114 patients (68 males; mean age: 59.1 years) using a 3.0-T magnetic resonance (MR) scanner and visually assessed by two radiologists. T2-SLL presence in 22 brain areas was evaluated using the following system: 0 for absence, 1 for <50% surface, 2 for ≥50% but not the entirety, and 3 for the entirety. After assessing inter-rater agreement, the scores were averaged. To investigate the causes of T2-SLL, an experimental MR imaging (MRI) was performed on a healthy male volunteer. To evaluate the chemical shift effect, the bandwidth and encoding direction were modified. To assess the magnetic susceptibility effect, T2*WI was performed using varying echo times (TEs).
Results: A moderate inter-rater score agreement (κ=0.556) was observed. T2-SLL was identified in all participants and was most frequently observed on the frontal and lateral sides of the midbrain and pons, with the highest occurrence on the frontal of the upper pons (median 2.0; interquartile range 2.0–3.0). In the experimental MRI, no differences in T2-SLL were observed across the varying bandwidths and encoding directions. However, the superficial low signal for T2WI thickened as the TE lengthened, similar to blood vessels, suggesting a magnetic susceptibility effect.
Conclusion: T2-SLL can be regarded as a normal structure that may be associated with blood vessels.
