COPULA FRANK UNTUK PERHITUNGAN VALUE AT RISK PORTOFOLIO BIVARIAT PADA MODEL EXPONENTIAL GENERALIZED AUTOREGRESSIVE CONDITIONAL HETEROSCEDASTICITY

Stocks are one type of investment that promises return for investors but often carries a high risk. Value at Risk (VaR) is a measuring tool that can calculate the amount of the worst loss that occurs in a stock portfolio with a certain level of confidence and within a certain time period. In general, financial data have a high volatility value, which causes the residuals are not normally distributed. ARCH/GARCH modoel is used to solve the heteroscedasticity problem. If the data also have an asymmetric effect, it is modelled with Exponential GARCH model. Copula-Frank is part of the Archimedian copula which is used to solve empirical cases. The data on this study were BBCA and KLBF stock price return data in the observation period 30 December 2011 – 6 December 2019. Furthermore, to test the validity of the VaR model, a backtesting test will be carried out using the Kupiec Test. The results showed that the best model used for BBCA stocks was ARIMA (1,0,1) EGARCH (1,1) and for KLBF stocks was ARIMA (1,0,1) EGARCH (1,2). The amount of risk with a 95% confidence level used a combination of the EGARCH and Copula-Frank models was 2.233% of today's investment. Based on the backtesting test used the Kupiec Test, the VaR model of the portfolio obtained was declared valid.

Transparency in Spanish archive and library websites: A comparative study

Transparency is a principle that has attracted a good deal of international attention in recent years, especially in connection with combatting corruption and building open, participatory governments accountable to their citizens. Public libraries and archives are not only information suppliers, but also public bodies obliged to provide the citizenry with information about their own governance and activities. Those obligations are laid down in Spanish Act 19/2013 of 29 December on Transparency, Access to Public Information and Good Governance (Spanish initials LTAIPBG). This article describes the results of applying a transparency measuring tool, TransPa_BA, to 106 regionally administered national historic archives and national public libraries. The tool, in turn the result of a research project, includes 20 indicators to measure active public disclosure by public libraries and 22 by archives in keeping with the provisions of the aforementioned Act. The indicators and their respective parameters (visibility, content, form, accessibility, reusability, dating and currency) provide guidelines to enable these institutions to comply with transparency and accountability requirements by furnishing society in general and their stakeholders in particular with information on their activities and performance in key areas. Further to the findings, the target institutions have made hesitant attempts to enhance transparency with respect to earlier inquiries. Public libraries are observed to be more active than archives, although the transparency scores obtained are low due to the failure to provide information on some indicators as well as on parameters such as dating and reusability. Both types of institution have a long road ahead in the pursuit of greater transparency.

Preparing Modified Bonding Representations Inventory: Challenges and Solution

Collecting data on learners' performance in different chemistry contents and analysing them to identify their knowledge and understanding in related content areas is a major task of Chemistry Education Research. The data collection process on the learners' content knowledge and understanding of content knowledge requires a standard measuring tool. The preparation of standardized tools for measuring academic achievement requires computer software. All software used in the standardization of a tool comes at a cost and requires training for the researcher involved in handling the situation, which can impede the smooth running of a project. The same was the situation when the author was working on modifying the bonding representations inventory (BRI) for its local use in South Africa. The data analysis laboratory was situated in a different city, 500 km away from the researcher's field of work. Owing to the long distance and communication delay, the author was concerned with delays in the project. It is known that necessity, which can create an opportunity. The Microsoft Excel (MS-Excel) platform was used for standardizing the modified BRI because MS-Excel is available as a standard in MS-Office on the Windows platform. This paper presents a fact. That, a tool can be standardized by using MS-Excel without any complexity.

Assessment of systemic joint laxity in the clinical context: Relevance and replicability of the Beighton score in chronic fatigue

BACKGROUND: Persistent symptoms in patients with systemic joint laxity (SJL) are often equivalent with complications. Screening for SJL is an important part of the assessment of musculoskeletal phenotype. The common measuring tool, the Beighton score (BS), still has unclear evidence. OBJECTIVE: To assess the Beighton score in a clinical context for (1) ability to classify SJL as absent or present (criterion validity), and (2) interrater reliability (physician-physiotherapist), for a dichotomous cut-off (yes/no), as well as for interpretation in categories (no, some, clear SJL). METHODS: This real-world observational study included 149 consecutive patients seeking secondary care for investigation of possible myalgic encephalomyelitis/chronic fatigue syndrome. Assessment was done during a routine examination. Data were evaluated with Cohen’s kappa and Spearman’s rho. RESULTS: BS criterion validity showed poor agreement with the assessment of SJL: percentage agreement was 74 % and kappa 0.39 (3-cut level), 73 % and kappa 0.39/0.45 (4-/5-cut level). The best interrater reliability was moderate (rho 0.66) for interpretation in categories. CONCLUSIONS: The BS alone was not a reliable proxy for SJL and should be supplemented with a targeted history. Nevertheless, its interrater reliability was acceptable, and the categorised score appears to have greater clinical relevance than the dichotomous score.

ALTERNATIF PENILAIAN EVALUASI PEMBELAJARAN PASCA PANDEMI COVID – 19 PADA JENJANG PENDIDIKAN SEKOLAH DASAR

Education is a conscious and planned effort to create a learning atmosphere and learning process that is actively able to make students develop their potential. Education is expected to be able to create students who have religious spiritual strength, self-control, personality, intelligence, and noble character. These skills are not only needed for themselves, but also useful for the people of the nation and state. Efforts that can be made to ascertain whether an educational goal has been achieved is by conducting an evaluation. This evaluation is carried out to determine whether a program is feasible. In addition, evaluation is intended to control, guarantee, and determine the quality of education related to the sharing of educational components. Evaluation is carried out at all levels and types of education in order to be accountable to students related to the implementation of education that has been carried out by an educational institution. Thus, between teaching and learning activities and evaluation is a continuous series and cannot be separated. This is because evaluation is used as a useful measuring tool to determine and determine the level of success of students in learning activities.

Validation of the Romanian Version of the Toronto Empathy Questionnaire (TEQ) among Undergraduate Medical Students

Medical professionals require adequate abilities to identify others’ emotions and express personal emotions. We aimed to determine the validity and reliability of an empathy measuring tool in medical students for this study. We employed Spreng’s Toronto Empathy Questionnaire (TEQ) as a starting point for this validation. The process was performed in several steps, including an English-Romanian-English translation and a focus group meeting to establish each question’s degree of understandability and usability, with minor improvements of wording in each step. We checked internal and external consistency in a pilot group (n = 67). For construct and convergent validity, we used a sample of 649 students. The overall internal and external reliability performed well, with Cronbach’s alpha = 0.727 and respective ICC = 0.776. The principal component analysis resulted in 3 components: prosocial helping behavior, inappropriate sensitivity, dismissive attitude. Component 1 includes positively worded questions, and components 2 and 3 include negatively worded questions. Women had significantly higher scores than men in convergent validity, but we did not highlight any differences for other demographic factors. The Romanian version of the TEQ is a reliable and valid tool to measure empathy among undergraduate medical students that may be further used in subsequent research.

A scale development study: Hemodialysis comfort scale version II

Aim Aim of this study was to develop a valid and reliable measuring tool in order to evaluate comfort of patients receiving hemodialysis treatment. Background There has been available a scale developed to evaluate comfort of hemodialysis patients “HDCS (Hemodialysis Comfort Scale).” Due to HDCS consisted of nine items and evaluated comfort in two sub-dimensions, researchers who developed HDCS, stated that number of scale items and dimensions is not sufficient to fully evaluate comfort. Therefore, (Hemodialysis Comfort Scale Version II) HDCS-II was developed with this research and its development process were discussed in this article. Materials and Methods Sample of this methodological research was consisted of 436 chronic hemodialysis patients, treated at five hemodialysis centers between October 2018 and May 2019. In process of creation item pool, comfort theory and literature was examined. The items in the old scale were also revised and included. Thereby a new question pool of 87 items was created. This draft scale was sent for expert opinion. In validity of scale; content validity index, exploratory and confirmatory factor analysis were used. In reliability study; Item analysis, cronbach’s alpha reliability coefficient, parallel form reliability and item analysis based on upper-lower group averages were used. Results There was consistency between expert views relating to items in scale. According to exploratory factor analysis, scale consisted of six dimensions. Cronbach alpha coefficient of 26-item scale was 0.79. Alpha values of the six factor in scale were, respectively; for physical relief 0.83, for physical ease 0.71, for psychospiritual ease 0.87, for psychospiritual transcendence 0.85, for environmental transcendence 0.82, and for sociocultural ease 0.61. Conclusion HDCS-II is a 5-point likert type and consists of 26 items and 6 factors. This scale is a valid and reliable measurement tool that can be used to determine comfort of patients undergoing hemodialysis treatment.
