This study involves an investigation into the act of risk profiling, and whether or not it will differ during different market trends. The literature review involves an in-depth discussion about risk tolerance and what factors determine it, as well as behavioural finance, bull and bear market phases, strategic asset allocation, and the duty of a diligent financial advisor to his or her clients. In order to conduct the investigation, 210 respondents under the age of 33 years filled out actual risk profile questionnaires, each having one of three market conditions simulated: bear market conditions, bull market conditions, or no market conditions (current market conditions assumed). These three different simulated market conditions form the three groups which were to be compared to each other. Each respondent was categorised based on the type of investor he or she was deemed to be: conservative, moderately conservative, moderate, moderately aggressive, or aggressive. The three groups were then tested using a paired samples T test for statistically significant differences between their means. At a 5% level of significance, the evidence showed that there was not a statistically significant difference between risk profiling during a bull market and risk profiling during a bear market, which resulted in failure to reject the null hypothesis.

This study aims to investigate whether the use of six selected short stories throughout the duration of a 14-week course could enhance students’ reading comprehension achievement at the end of the semester. Out of the six short stories read, three were chosen as in-class assignments known as ‘Personal Reading Logs’ (hereafter, PRLs). One group of semester two Diploma students taking a reading skills course was selected through a convenience sampling method. A pre-test was conducted by having the students answer a past semester reading quiz of which the results would then be compared to their post-test (final reading exam) results. A paired samples t-test revealed no significant difference in the reading scores of the pre-test and the post-test, t (17) = -.265, p > .05. Since the p-value was bigger than 0.05, this indicated that the mean reading score of the post-test (M = 50.556) was not significantly higher than the mean reading score of the pre-test (M = 49.722). Therefore, the null hypothesis which stated that there was no difference in the mean score of the pre-test and post-test was retained. Overall, the result refuted the findings of other studies promoting the effectiveness of using short stories to enhance L2 reading comprehension achievement.

This empirical research applies cointegration in the traditional measurement method first to build directed weighted networks in the context of stock market. Then, this method is used to design the indicators and the value simulation for measuring network fluctuation and studying the dynamic evolution mechanism of stock market transaction networks as affected by price fluctuations. Finally, the topological structure and robustness of the network are evaluated. The results show that network structure stability is strong in the bull market stage and weak in the bear market stage. And the convergence rate of the dynamic evolution of network fluctuation is higher in the bull market stage than in the bear market stage.

This paper investigates how China’s stock market reacts to short-term interest rates, as represented by the Shanghai Interbank Offered Rate (Shibor). We adopt the Markov Regime Switching model to divide China’s stock market into Medium, Bull and Bear market; and then examine how Shibor influences market returns and risk in different market regimes. We find that short-term interest rates have a significant negative effect on stock returns in Medium and Bull market, but could not affect stock returns in Bear market. In addition, different maturities of Shibor have different effects on stock returns. Furthermore, we find that the short-term interest rates have a negative effect on market risk in Bull market, but a positive effect in Bear market. Our findings show that China’s market is quite peculiar and distinctive from the U.S. market or other developed countries’ markets in many ways.

Reasoning skills are very important in encouraging students to think more critically and logically, as depicted in the Malaysian Education Development Plan (2013-2025). Therefore, this study looked into improving the Differentiation Reasoning Level (DRL) of reasoning skills among students for a topic in the Additional Mathematics subject,  known as Differentiation, through reasoning learning strategy. The study participants consisted of a total of 31 students from a secondary boarding school in Johor, selected through a purposive sampling method. A pre-test was carried out for the participants, from the advanced level, followed by a number of repetition tests, before the post-test assessment was conducted. The data collection for this study employed a set of Reasoning Test on Differentiation (RTD) and 10 sets of learning activities on Differentiation based on modified Marzano Rubric for Specific Task of Situations (1992). This dimension involved four types of reasoning skills, namely,  comparison, classification, inductive, and deductive. The survey data, through paired samples t-test, revealed a significant difference between the mean scores in pre-test and post-test (p <0.05). In addition, the paired sample t-test showed a significant difference on the level of reasoning among students from each construct in the reasoning skills before and after using this module. In conclusion, the Marzano Model of Dimensional Learning (1992) is a thinking skill model that can help improve students' reasoning skills. The model covers analysis aspects of what has been learned by implementing the process of identifying reasons, which will help students to add and expand their knowledge. The findings also implied that, the processes of teaching and learning play an important role in ensuring students’ capability to emphasize on the implementation process of reasoning skills

Complex Instruction Team Product (CITP) learning model is one of the creative-innovative learning models which is assumed to be able to empower scientific attitudes and learning outcomes of students. This study aimed to determine students’ scientific attitudes and cognitive learning outcomes by implementing CITP learning model. This research used one-group pretest-posttest design. The sample was 18 tenth graders of academic year 2017/2018 of State Senior High School 6 of Ambon, Maluku Province. The data was analyzed using N-Gain test which then continued with dependent samples t-test. This result indicated that the highest achievement of students’ scientific attitudes were honesty and creativity (54). Meanwhile, the N-Gain score of students' cognitive learning outcomes was 0.61. In addition, the results of paired samples t-test show that there was a significant difference (p<0.05) between the students’ cognitive learning outcomes before and after the application of CITP learning model. This means that the application of CITP learning model can improve students’ scientific attitudes and cognitive learning outcomes.

Objective: The aim of this study was to compare the total medicament doses and recovery profiles of patients for whom Bispectral Analysis (BIS) monitor was used to monitor sedation. Study design: Thirty-four uncooperative paediatric patients aged 3-6 years who attended to the Department of Pediatric Dentistry for dental treatment were enrolled in the study. Patients were randomly divided into 2 groups of 17 patients each. Physiological variables including oxygen saturation, blood pressure and heart rate were recorded. In one group (BIS-monitored group), drugs were administered to maintain patients’ BIS values between 60-70, while the other group (Non-BIS-monitored Group) was not monitored using BIS. Data was evaluated by Chi-square, Mann Whitney U, Independent Samples t, Paired Samples t and Wilcoxon signed tests, with a p-value of &lt;0.05 considered to be statistically significant. Results: There was no significant difference in total anesthetic doses, incidence of adverse events or recovery profiles of patients between non- BIS-monitored and BIS-monitored groups (p≯0.05). However, distinct correlation was determined among mean values of UMSS and BIS values (p&lt;0.05). Conclusion: BIS represents no advantage over the current commonly accepted methods for monitoring sedation depth in children.
