Socio-Economic Determinants of Stock Market Behaviour: A Comprehensive Analysis of Investment Pattern and Decision-Making

Abstract Investor's investment decisions and market outcomes are thought to be systematically influenced by both market dynamics and information structure. Therefore, the study’s main purpose was to identify the factors influencing the investment decision of stock market investors of India. The study also identified the effect of investors' socioeconomic profiles on their stock market investing behaviour. The study was conducted on 151 individual stock market investors of Haryana state. To collect the data a structured questionnaire was used. The data were analyzed using frequency, percentage, crosstab, chi-square, KMO test, Bartlett's test of sphericity and factor analyses. The reliability of data was tested using Cronbach's Alpha. Hypothesis was set to know whether there is any relationship between demographic variable and investment pattern of investors. This study found three major factors which influence the investment decisions of stock market investors. The factors that were discovered were the investing goal, liquidity, and risk attitude. The hypothesis's outcome demonstrated a favorable correlation between investors' investing patterns and demographic characteristics.

Validity and reliability of the Arabic version of knowledge, attitudes, and practices toward COVID-19 preventative behaviors (KAP COVID-19).

Even though the innovation of COVID-19 vaccination effectively protects against the virus, practicing preventative behaviors is still essential. However, public adherence to preventive behaviors relies mainly on the individuals' knowledge, attitudes, and practices (KAP) toward COVID-19 preventative behaviors. Therefore, it is crucial to evaluate these aspects. Nevertheless, there is no validated scale that assesses KAP toward COVID-19 preventative behaviors. To evaluate the psychometric properties of the Arabic version of knowledge, attitudes, and practices toward coronavirus disease 2019 (COVID-19) preventative behaviors. A quantitative descriptive cross-sectional design was used to develop and evaluate the psychometric properties of KAP through specific stages: item development, face, content, convergent and construct validity evaluation, and internal consistency. Data were collected online through "google forms" from June 2020 to July 2020. Both exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were used to assess the construct validity. A total of 1,363 participants completed the scale. The overall Cronbach's alpha was 0.83, indicating good internal consistency. Exploratory factor analysis supported structural validity for all the scale items with KMO 0.78, 0.60, and 0.81, respectively, and Bartlett's Test of Sphericity = (p < 0.05). Convergent validity was confirmed by a moderate correlation between the KAP scale items, knowledge ranging from r = 0.11 (p < 0.01) to r = 0.62 (p < 0.01), attitude ranging from r = 0.158 (p < 0.01) to r = 0.584 (p < 0.01), and practice ranging from r = 0.383 (p < 0.01) to r = 0.774 (p < 0.01). The psychometric properties of the scale indicate that the KAP is a valid and reliable scale that can be utilized to evaluate the level of KAP toward COVID-19 preventative behaviors among the population in Saudi Arabia.

Multiple Myeloma: Validation of the Values and Preferences Elicitation Questionnaire- Cure and Survival Preference Scale (VPEQ-CSPS)

BackgroundWith the emergence of many novel therapies, the treatment decisions for multiple myeloma (MM) are increasingly guided by concerns of quality of life, achievement of cancer-free remission, living a longer overall survival, and a relentless search for a cure; however, the impact of various decision-making factors on patients’ actual therapy choices and the patients’ desire for cure and survival is mainly unknown. The lack of a valid and reliable measure for uncovering patients’ preferences for cure and survival makes it more challenging to put this factor into the actual treatment decision equation. PurposeThis study examined the psychometric properties of the Values and Preferences Elicitation Questionnaire-Cure and Survival Preference Scale (VPEQ-CSPS) instrument. MethodsThe VPEQ-CSPS instrument was deployed using an anonymous Qualtrics online survey to patients diagnosed with MM within the network of International Myeloma Foundation online patient support groups across the United States. One hundred seventy-four (N = 174) valid responses were obtained and used to examine the validity and reliability of the VPEQ-CSPS. ResultsExploratory factor analysis (EFA) revealed a Kaiser-Meyer-Olkin value of 0.72 indicating excellent sample adequacy. A statistically significant Bartlett's test of sphericity (P < .001) indicated significant correlations among the variables of the dataset to conduct the EFA. The internal consistency coefficients indicated adequate reliability of the instrument with Cronbach's alpha value at 0.80. The EFA and parallel analysis revealed the 5-item VPEQ-CSPS as a valid and reliable unidimensional scale that can be used by oncology clinicians to elicit their patient's preferences for cure and survival. This new instrument has the potential to contribute to the achievement of shared decision-making for myeloma treatment decisions.

THE IMPORTANCE OF SELF-EMOTIONAL COMPETENCY MODEL FOR MIDDLE SCHOOL LEADERS IN THE ERA OF SOCIETY 5.0: A PILOT STUDY

The self-emotional competency model can be used as a measurement tool to increase the emotional qualities of school leadership in facing the change in the education era of Society 5.0. However, validation of the self-emotional competency model using exploratory factor analysis (EFA) is still scarce. Therefore, this pilot study is conducted to identify the applicability of the emotional competency model of middle leaders in primary schools through exploratory factor analysis (EFA). This study employed a quantitative approach using a survey method. A questionnaire was used as a research instrument. The instrument contained 18 items. A total of 179 respondents participated in this pilot study. The validity and reliability of the instrument were obtained through descriptive analysis of Cronbach's Alpha reliability and exploratory factor analysis (EFA) using SPSS version 27 software. The overall analysis shows that 13 items meet the EFA fit requirements with Kaiser-Meyer-Olkin (KMO) values of more than 0.6. Bartlett's test values were significant, with item communalities values exceeding 0.3 and Eigen values exceeding 1.0 at a percentages of variance exceeding 60 percent. The Cronbach's Alpha coefficient was above 0.70 for all items. A total of five items were removed. The findings of the study show that the instrument of self-emotional competency instrument has very high validity and reliability and has the potential to be used as a guide in the development of self-emotional competence of middle leaders in Malaysia. A positive impact is essential in generating emotionally intelligent leaders who are competitive and capable to lead the school community towards the era of Society 5.0 especially in primary school in Malaysia.

Barriers to Implementing Safety Measures During COVID-19 Pandemic on Building Construction Projects in Nepal

The COVID-19 pandemic caused disruptions in building construction projects, with safety measures being a major concern for workers and the public. This study aims to assess the barriers to safety measures during the COVID-19 pandemic on building construction projects in Nepal. A total of 330 responses were collected from construction professionals in Nepal using a Likert scale. To ensure the data's suitability for factor analysis using Principal Component Analysis, Kaiser-Meyer-Olkin, Bartlett's Sphericity test, inter-component correlations, and Cronbach alpha scores for internal consistency were checked, and principal components were extracted. A 25-item safety barrier to safety measures in building construction projects during the COVID-19 pandemic was identified through an extensive review of the literature; six components were retained using Principal Component Analysis which represented the model of choice and explained 62.86 % of the data variance. The components were; inappropriate safety guidelines, psychological working pressure, inadequate hygiene monitoring and control, lack of safety awareness, improper working culture, and insufficient planning and scheduling. The internal consistency for the retained components was high; Cronbach α scores ranged from 0.72 to 0.796. “Inappropriate Safety Guidelines” was the most critical barrier to implementing safety measures during the COVID-19 pandemic in building construction projects, according to the rankings of the six identified components. It is recommended that construction professionals and regulatory bodies prioritize the development and adherence to robust safety protocols tailored to pandemic conditions. Regularly updating and reinforcing these guidelines will be crucial in safeguarding the health and well-being of workers while ensuring project continuity. Additionally, investing in thorough training and awareness programs can significantly mitigate this barrier's impact.

Outcomes in Acute Lymphoid Leukemia Patients with Incomplete Hyper-CVAD Cycles

Introduction: Hyper-CVAD (hyperfractionated cyclophosphamide, vincristine, doxorubicin and dexamethasone) is a commonly used regimen in acute lymphoblastic leukemia (ALL) for a total of 4 A/B intensive courses. This regimen is often limited due to multiple complications including organ dysfunction and medication toxicities along with high rates of relapse or disease progression. Prior studies have indicated five-year overall survival (OS) of 39% with severe prolonged myelosuppression being a common complication. In one study 6% of patients died during induction therapy. Here we provide clinical outcomes of non-transplanted patients with ALL receiving hyper-CVAD regimen in our tertiary referral center. We assessed overall survival, mortality rates, and complications during induction therapy with hyper-CVAD in our cohort of adult patients. Methods: We conducted a comprehensive, retrospective study at our center, evaluating outcomes of non-transplant eligible ALL patients treated from February 2003 to October 2022. We excluded patients without all available diagnostic information, and those who underwent allogeneic stem cell transplantation (SCT). We classified the patient based on their BCR - ABL1 gene status. Groups were subcategorized by highest cycle of Hyper-CVAD completion, with reason for cessation (medication toxicity/organ dysfunction, lost to follow up, progressive disease/relapse) elicited for those who did not complete all treatment cycles. Overall survival was analyzed using T-Test, ANOVA and Bartlett's test. Statistics are descriptive and our institutional review board approved this retrospective study. Results: We report outcomes of 43 ALL patients who did not undergo SCT. Median age at diagnosis was 52 years (range of 18-71 years). 33/43 (76.7%) patients received Hyper-CVAD regimen. 2/33 (6.1%) completed the entire course through 4B. 12 (36.3%) out of 33 patients received less than cycle 3b; 21/33 (63.6%) received at least cycle 3b. 2/6 (33.3%) completed up to cycle 1B, 2/11 (18.2%) completed up to cycle 2B, 13/25 (52%) completed up to cycle 3B, and 2/33 (6.1%) completed up to cycle 4B. 12/33 (36.4%) of patients were not able to complete more than cycle 3A due to organ dysfunction and intolerance, being lost to follow up, progressive disease or relapse, or participation in a trial. For the patients who received less than cycle 3b, the reasons for early discontinuation were: organ dysfunction 6/12 (50%), progressive disease or relapse 3/12 (25%), lost to follow up 2/12 (16.7%), or participation in a trial 1/12 (8.3%). Median overall survival (OS) for patients who received up to cycle 3A was 640 days compared to a median of 711 days for those who received at least cycle 3B. Median OS for patients who received up to cycle 3A in the Ph-negative group was 21.0 months and 23.1 months in the Ph-positive group. Median OS for patients who received at least 3B in the Ph-negative group was 20.9 months and 23.9 months in the Ph-positive group. Conclusion: Hyper-CVAD is the mainstay of ALL treatment. Induction chemotherapy in ALL is commonly associated with myelosuppression and documented infections (sepsis, pneumonia, port infection). Other significant side effects include neurotoxicity, liver and kidney failure. Induction chemotherapy in some patients was a limiting factor in completing therapy. We report the different reasons for terminating the treatment course to be: organ dysfunction or intolerance such as liver injury, neutropenic fever, septicemia, subarachnoid hemorrhage, renal failure, congestive heart failure, respiratory failure requiring intubation, port infection, cytokine release syndrome, and neurotoxicity. Median OS was longer in the Ph positive subgroup but the mortality rates for this subtype was not different between the patients who received up to cycle 3A verses those that received at least cycle 3B. In this study, our descriptive analysis did not show a clinically meaningful difference in survival in patients who did not finish the total induction course. A limitation of this study was not analyzing intrathecal prophylaxis as involvement of the central nervous system is a major clinical concern. Herein, we suggest a personalized approach in treating ALL patients considering infection risk, disease cytogenetic risk and depth of response to help adjusting the number of induction cycles based on the mentioned risk factors.

ObjectiveEnuresis is associated with attentional and emotional comorbidities in 20 to 30 % of cases. The Short Screening Instrument for Psychological Problems in Enuresis (SSIPPE) is a questionnaire that allows the initial screening of these comorbidities. This study aimed to translate, culturally adapt, and validate the SSIPPE for Brazilian children and adolescents (SSIPPE-Br). MethodsSix steps were performed for translation and cross-cultural adaptation: translation, synthesis of translations, back-translation, preparation of the pre-final version of the translated instrument, test of comprehensibility of the pre-final version of the tool, and elaboration of the instrument cross-culturally adapted for Brazil, named 13-itens version SSIPPE-Br. To validate the SSIPPE-Br, a cross-sectional study was carried out, in which the validated Brazilian version of the Child and Adolescent Behavior Inventory (CABI) was used. ResultsValidation was performed on 127 children and adolescents with a mean age of 9.7 ± 2.8 years, 48 % male. The reliability was estimated using Cronbach's alpha, ranging from 0.86 to 0.89, indicating good internal consistency. The factorial analysis had a good agreement adjustment (KMO 0.755, Bartlett's test < 0.001) and explained 70.5 % of the data variability. In the reproducibility analysis, the Kappa coefficient ranged from 0.94 to 1, which can be considered almost perfect. A highly significant (p-value < 0.001) and direct correlation existed between the three SSIPPE-Br domains and all evaluated CABI domains. ConclusionThe SSIPPE-Br is a valid and reliable tool for emotional problems screening and ADHD symptoms in children and adolescents with enuresis whose first language is Brazilian Portuguese.

Quality markers screening of traditional Chinese medicine prescriptions based on the multi-factor analysis strategy: Jin-Zhen oral liquid as a case

BackgroundJin-Zhen oral liquid (JZOL), a well-known traditional Chinese medicine prescription (TCMp), has extensively been used to treat acute bronchitis in children more than four hundred years in China. However, the current quality control standard of JZOL is inadequate, posing challenges for its internationalization. PurposeIn this study, a Q-marker screening strategy based on multi-factor analysis was proposed to comprehensively evaluate anti-inflammatory Q-markers of Jin-Zhen oral liquid (JZOL). MethodsFirstly, the chemical profile and the pharmacokinetics properties of multiple components in JZOL were characterized by UPLC-Q/TOF-MS and UPLC-QqQ-MS. By integrating the measurable and absorbed components, twenty-two components with structures accurately defined, were selected as candidate Q-markers of JZOL. Following that, a network connecting 22 components and targets closely associated with bronchitis was established. Afterwards, a multi-factor analysis mode was developed to balance the components’ multiple characteristics, and screen out the anti-inflammatory Q-markers in JZOL. Finally, the anti-inflammatory activity evaluation was conducted by LPS-induced RAW 264.7 macrophages to prove the representativeness of anti-inflammatory Q-markers in JZOL. ResultsAs a result, a total of 92 components were characterized in JZOL and the pharmacokinetics properties of 11 bioactive components in vivo were further characterized. Then, an overlapping of 46 targets involved in the interactions of selected 22 candidate Q-markers and the regulation of bronchitis inflammation were collected. Subsequently, a multi-factor analysis was developed on 22 candidate anti-inflammatory Q-markers covering five factors, with the statistic KMO values of 0.645, and the P values of Bartlett's Test equal to 0.000. A total of seven ingredients (aloeemodin-8-O-β-d-glucopyranoside, baicalin, chrysin-7-O-β-d-glucuronide, oroxylin A 7-O-β-d-glucuronide, wogonoside, chrysophanol-8-O-β-d-glucopyranoside, and skullcapflavone II) were selected as Q-markers of JZOL, and the inhibitory effects of these candidate Q-markers on the secretion of inflammatory cytokes (NO, IL-6, IL-1β, and PGE2) in lipopolysaccharide (LPS)-stimulated RAW264.7 cells were evaluated and confirmed. ConclusionThis study not only offers a fresh approach to uncovering Q-markers in the quality control research of TCMps but also identifies the suitable anti-inflammatory Q-markers for JZOL for the first time, with the potential to serve as a reference for existing quality control standards of JZOL.

Validity and Reliability of The Persian Version of Uterine Fibroid Symptom and Health-Related Quality of Life Questionnaire: A Psychometric Study.

Women with uterine fibroids (UFs) experience many clinical manifestations that affect their quality of life (QOL). The Uterine Fibroid Symptom and Health-related Quality of Life (UFS-QOL) questionnaire is an English instrument specifically designed to assess fibroid-related symptoms and their impact on QOL. This study aims to investigate the reliability and validity of the Persian version of the UFS-QOL questionnaire in Iranian women with UF. In this psychometric study, women with UFs who presented to Imam Hossein Hospital (Tehran, Iran) between August 2022 and January 2023 were enrolled in this study. A forward-backward approach was applied to translate the UFS-QOL questionnaire into Persian. The reliability of the UFS-QOL questionnaire was assessed by internal consistency and test-retest correlation. Confirmatory factor analysis (CFA) was used to assess convergent validity between items and subscales of the UFS-QOL questionnaire. Pearson's correlation coefficient was used to assess convergence validity between subscales of the UFS-QOL and the World Health Organization Quality of Life Brief Version 26 questionnaire (WHOQOL-BREF-26). Overall, we assessed 226 women with UFs. All subscales of the UFS-QOL questionnaire had acceptable internal consistency (Cronbach's alpha>0.7). Test-retest analysis indicated significant positive correlations between two measurements of all subscales of the UFS-QOL questionnaire: symptom severity (P<0.001), concern (P<0.001), activities (P<0.001), energy/mood (P<0.001), control (P<0.001), self-consciousness (P=0.002), and sexual function (P<0.001). The Kaiser-Meyer-Olkin (KMO) measure value was 0.920, and the result of Bartlett's test of sphericity was significant (P<0.001). CFA identified six factors for the health-related QOL (HRQL) questionnaire, which explained 73.827% of the total variation. Most subscales of the UFS-QOL questionnaire correlated with domains of the WHOQOL-BREF-26 questionnaire (P<0.05). The Persian version of the UFS-QOL questionnaire is a valid and reliable instrument to evaluate UFrelated symptoms and QOL among Iranian women.

The population consisted of 101 students from various semesters and courses. Implementation involved quizzes, workshops, a classroom project, and personal challenges as evaluation activities. The FC materials included explanatory videos, solved problems, readings, and slides. These materials were organised on the Moodle platform. The research employed quantitative and qualitative methodologies, formulating five hypotheses and designing a 14-indicator survey. The data were analysed using statistical methods such as Cronbach's alpha, Guttman's split-half, Kolmogorov–Smirnov, KMO analysis, Bartlett's test, principal component analysis, Kruskal–Wallis ANOVA, and Spearman's rho. Results indicated excellent reliability of the survey indicators, non-parametric data, and good adequacy of the proposed structure. Analysis indicated that the implementation of this methodology leads to significant benefits in terms of satisfaction, emotional engagement and stimulation levels, resulting in more effective learning and preference over the traditional approach. The perception of technology, timing, and content of videos varied among different courses. Positive comments from students supported the benefits of the hybrid methodology. It was recommended to improve the selection and quality of study materials.

Consumer Purchase Intention Post COVID-19 Pandemic Through Marketplace : An Action Learning Study

This study aims to find out and complement existing information related to the influence of e-trust, e-satisfaction, and social influence on purchase intention mediated by e-value. This is a survey research that uses quantitative methods with data collection techniques through online questionnaires which were distributed to 700 marketplace consumer respondents who had purchased cell phones or gadgets from January 2023 to June 2023. There were 700 questionnaires distributed and 233 returned, but only 155 were used according to this study’s criteria. This research was carried out through a validity test and a reliability test through the MSA test with the KMO and Bartlett tests. The hypothesis test used SEM-PLS through SmartPLS 3.3.9 software. The results showed that four of the seven hypotheses proposed in this study were proven positive and significant: the effect of e-trust on e-value and purchase intention, the effect of social influence on e-value and purchase intention, while the other hypotheses which could not be proven (not significant) were the effect of e-satisfaction on e-value and purchase intention, and the effect of e-value on purchase intention. In addition, indirectly, e-value plays a role in mediating the effect of e-trust and social influence on purchase intention because it is able to change (weaken) the significant effect to be insignificant. As for mediating the effect of e-satisfaction on purchase intention, the e-value variable is unable to mediate (strengthen) because the results are not significant or the same as the direct effect of e-satisfaction on purchase intention.

This scale can be used by both pediatric nurses and school nurses to evaluate children's return to school. Additionally, children and families can get an idea about preparing for returning to school by applying this scale.

Efektivitas Model Pembelajaran Open-Ended dan Make A Match dengan Menggunakan Teori Belajar Konstruktivistik terhadap Prestasi Belajar Siswa

Learning activities at school are important activities for students, especially learning activities that are held in the classroom. Learning activities between teachers and students must be established in harmonious interactions and relationships, so that in learning activities in the classroom there is a conducive and active atmosphere. This study used three classes, namely Experiment I class (Open-Ended), Experiment II class (Make A Match) and Control class (Descriptive/Exposure). Before giving the treatment, firstly take the value data for the initial data to match the three classes. For initial data analysis, a normality test was calculated with the Liliefors test, homogeneity test with the Bartlett test, and the average comfort test using one-way Anava. After giving the treatment and evaluation tests, the final data analysis calculations were carried out to test the research hypothesis. For the final analysis, it was carried out as the initial analysis plus the t test. The research results for hypothesis 1, there is a difference in the average learning achievement between experimental class I, II and control. For hypothesis 2, the learning achievement of the experimental class I is better than the control class. For hypothesis 3, the learning achievement of experimental class II is better than the control class. For hypothesis 4, there is no difference in learning achievement between experimental class I and experimental class II. So, learning using the Open-Ended model and the Make A Match learning model on Logarithmic Mathematics material is better than the Descriptive/Exposure learning model
