Analisis Faktor-faktor Pengungkapan Islamic Social Reporting (ISR) Pada Perusahaan Yang Terdapat Di Indeks Saham Syariah Indonesia (ISSI) Pada Tahun 2013-2016

Islamic Social Reporting (ISR) is an index of social responsibility disclosure that has a specific indicator of the ethical principles of Islam. Current research on the implementation of Islamic Social Reporting (ISR) is still oriented to sharia banking companies only, rarely research on the implementation of Islamic Social Reporting (ISR) is done on non-banking companies and other financial institutions such as capital markets, especially in Indonesia. This study aims to analyze what factors affect the widespread disclosure of Islamic Social Reporting (ISR). The sample used in this research is a manufacturing company that publishes annual report in btahun 2013-2016 in full, then companies listed in Indonesia Sharia Shares Index (ISSI) and use rupiah currency. Data analysis method used in this research is multiple linear analysis. Samples obtained by a total of 300 samples. The result of this research is to show that firm age has a positive and significant influence on Islamic Social Reporting (ISR) disclosure, for profitability variable, firm size and public stock ownership have no significant effect on Islamic Social Reporting (ISR) disclosure

Evaluation of appendicitis risk prediction models in adults with suspected appendicitis

Background Appendicitis is the most common general surgical emergency worldwide, but its diagnosis remains challenging. The aim of this study was to determine whether existing risk prediction models can reliably identify patients presenting to hospital in the UK with acute right iliac fossa (RIF) pain who are at low risk of appendicitis. Methods A systematic search was completed to identify all existing appendicitis risk prediction models. Models were validated using UK data from an international prospective cohort study that captured consecutive patients aged 16–45 years presenting to hospital with acute RIF in March to June 2017. The main outcome was best achievable model specificity (proportion of patients who did not have appendicitis correctly classified as low risk) whilst maintaining a failure rate below 5 per cent (proportion of patients identified as low risk who actually had appendicitis). Results Some 5345 patients across 154 UK hospitals were identified, of which two‐thirds (3613 of 5345, 67·6 per cent) were women. Women were more than twice as likely to undergo surgery with removal of a histologically normal appendix (272 of 964, 28·2 per cent) than men (120 of 993, 12·1 per cent) (relative risk 2·33, 95 per cent c.i. 1·92 to 2·84; P < 0·001). Of 15 validated risk prediction models, the Adult Appendicitis Score performed best (cut‐off score 8 or less, specificity 63·1 per cent, failure rate 3·7 per cent). The Appendicitis Inflammatory Response Score performed best for men (cut‐off score 2 or less, specificity 24·7 per cent, failure rate 2·4 per cent). Conclusion Women in the UK had a disproportionate risk of admission without surgical intervention and had high rates of normal appendicectomy. Risk prediction models to support shared decision‐making by identifying adults in the UK at low risk of appendicitis were identified

Long-wave interface instabilities of a two-layer system under periodic excitation for thin films

The stability of a system of two thin liquid films under AC electroosmotic flow is studied using linear stability analysis for long-wave disturbances. The system is bounded by two rigid plates which act as substrate. Boltzmann charge distribution is assumed for the two electrolyte solutions. The effect of van der Waals interactions in these thin films is incorporated in the momentum equations through the disjoining pressure. The base-state velocity profile from the present study is compared with simple experiments and other analytical results. Parametric study involving various electrochemical factors is performed and the stability behaviour is analysed using growth rate, marginal stability, critical amplitude and maximum growth rate in phase space. An increase in the disjoining pressure is found to decrease stability of the system. On the other hand, increasing the frequency of the applied electric field is found to stabilize the system. However, the dependence of the stability on parameters such as viscosity ratio, permittivity ratio, interface zeta potential and interface charge depends not only on the value of individual parameters but also on the rest of the parameters. Design of experiments (DOE) is used to observe the general trend of stability with different parameters.by Abhishek Navarkar, S. Amiroudine, E. A. Demekhin, U. Ghosh and S. Chakrabort
