    Previous studies on individual differences in mathematical abilities have shown that working memory contributes to early arithmetic performance. In this study, we extended the investigation to algebraic word problem solving. A total of 151 10-year-olds were administered algebraic word problems and measures of working memory, intelligence quotient (IQ), and reading ability. Regression results were consistent with findings from the arithmetic literature showing that a literacy composite measure provided greater contribution than did executive function capacity. However, a series of path analyses showed that the overall contribution of executive function was comparable to that of literacy; the effect of executive function was mediated by that of literacy. Both the phonological loop and the visual spatial sketchpad failed to contribute directly; they contributed only indirectly by way of literacy and performance IQ, respectively.

    Background: Studies have acknowledged that social media enables students to connect with and learn from experts from different ties available in the students' personal learning environment (PLE). Incorporating experts into formal learning activities such as scaffolding problem-solving tasks through social media, allows students to understand how experts solve real-world problems. However, studies that evaluate experts' problem-solving styles on social media in relation to the tie strength of the experts with the students are scarce in the extant literature. This study aimed to explore the problem-solving styles that the experts portrayed based on their ties with the students in problem-based learning (PBL) on Facebook. Methods: This study employed a simultaneous within-subject experimental design which was conducted in three closed Facebook groups with 12 final year management students, six business experts, and one instructor as the participants. The experts were invited by the students from the weak and strong ties in their PLE. Hinging on the Strength of Weak Ties Theory (Granovetter, 1973) and problem-solving styles (Selby et al., 2004), this study employed thematic analysis using the ATLAS.ti qualitative data analysis software to map the experts' comments on Facebook. Results:  The experts from strong and weak ties who had a prior relationship with the students showed people preference style by being more sensitive to the students' learning needs and demonstrating firmer scaffolding compared to the weak ties' experts who had no prior relationship with the students. Regardless of the types of ties, all experts applied all manner of processing information and orientation to change but the degree of its applications are correlated with the working experience of the experts. Conclusion: The use of weak or strong ties benefited the students as it expedited their problem-solving tasks since the experts have unique expertise to offer depending on the problem-solving styles that they exhibited.

    Risk management requires human judgements, from risk identification, assessment to response. Although automated tools are useful in handling large amounts of data and in performing complex calculations rapidly, humans undertake the entire risk management process. They bring to the process their intuitions, insights, previous experiences and skills. Therefore, creating a rich source of information of risks faced by an organisation. Ignoring human factors may impoverish information and limit risk management to only measurable factors. This study contributes to the field of decision-making and risk assessment by investigating and discussing in detail how to quantify subjective judgements using the Analytic Hierarchy Process (AHP). AHP is used to assess risk of an insurance company. It discusses how to do risk assessment by combining both intuition and analytic in the decision-making process. The study defines intuition as knowledge and experience, and analytic as the mathematics or quantitative analysis to derive the result. It demonstrates how Analytic Hierarchy Process (AHP) - a flexible multi-attribute or multi-criteria decision making tool, enables risk managers to use both intuition and analytic to do risk assessment. Risk assessment using AHP produces global priority weights representing the overall risk ranking of an insurance company. The study develops a risk assessment problem and uses AHP to organise and structure risks and sub-risks of the problem. It uses formative evaluation method with open-ended questionnaires to obtain feedbacks from risk managers on AHP. Three employees of a risk management department in a government agency assesses the risks using AHP. AHP strengths are easy to use and understand, improves risk assessment and useful for risk assessment problems that have scarce or no data. AHP limitation are the numbers and repetitiveness of the pairwise comparisons. The participants either ignore some of the pairwise questions or they answer randomly instead of deliberate judgements.

    Carbon spheres (CSs) were synthesized from sucrose by hydrothermal reaction. The synthesized materials were further
    activated with potassium hydroxide (KOH) at different concentrations. The effects of KOH concentration on the surface area
    and morphology were investigated. The route for pore formation and structural deformation in carbon spheres during
    activation has been proposed and discussed based on micrographs and porosity trends. It was suggested that the pore
    formation and structural deformation phenomena were due to the intercalating power of energized K+ into the carbon.
    This work provides an insight of the pore formation in carbon spheres for the development of adsorbents as well as for
    the understanding of the structural deformation of such materials at higher KOH concentrations.

    AIMS: Refugees are confronted with the task of adapting to the long-term erosion of psychosocial systems and institutions that in stable societies support psychological well-being and mental health. We provide an overview of the theoretical principles and practical steps taken to develop a novel psychotherapeutic approach, Integrative Adapt Therapy (IAT), which aims to assist refugees to adapt to these changes. This paper offers the background informing ongoing trials of IAT amongst refugees from Myanmar.

    METHODS: A systematic process was followed in formulating the therapy and devising a treatment manual consistent with the principles of the Adaptation and Development After Persecution and Trauma (ADAPT) model. The process of development and refinement was based on qualitative research amongst 70 refugees (ten from West Papua and 60 Rohingya from Myanmar). The therapeutic process was then piloted by trained interventionists amongst a purposively selected sample of 20 Rohingya refugees in Malaysia.

    RESULTS: The final formulation of IAT represented an integration of the principles of the ADAPT model and evidence-based techniques of modern therapies in the field, including a transdiagnostic approach and the selective use of cognitive behavioural treatment elements such as problem-solving and emotional regulation techniques. The steps outlined in refining the manual are outlined in relation to work amongst West Papuan refugees, and the process of cultural and contextual modifications described during early piloting with Rohingya refugees in Malaysia.

    CONCLUSIONS: IAT integrates universal principles of the ADAPT model with the particularities of the culture, history of conflict and living context of each refugee community; this synthesis of knowledge forms the basis for participants gaining insights into their personal patterns of psychosocial adaptation to the refugee experience. Participants then apply evidence-based techniques to improve their capacity to adapt to the serial psychosocial changes they have encountered in their lives as refugees. The overarching goal of IAT is to provide refugees with a coherent framework that assists in making sense of their experiences and their emotional and interpersonal reactions to the challenges they confront within the family and community context. As such, the principles of a general model (ADAPT) are used as a springboard for making concrete, manageable and meaningful life changes at the individual level, a potentially novel approach for psychosocial interventions in the field.

    Similarity measurement is a critical component in any case-based reasoning (CBR) system. CBR is
    a superior technique for solving new problems based on previous experiences. Main assumption in
    CBR relies on the hypothesis that states similar problems should have similar solutions. This paper
    describes a comparative analysis on several commonly used similarity measures (Canberra, Clark, and Normalized Euclidean distance) in retrieving phase of the case-based reasoning approach to facilitate supplier selection. In addition, the proposed agent-based supplier selection framework was designed to use customer’s defined weights to evaluate the price, volume, quality grade, and delivery date of supply materials, and also provide them with alternative products which are closest to their first order if it was out of stock. Finally, based on the proposed framework, a numerical example of the used approach is illustrated.

    There is some evidence stated that mood states might influence cognitive functioning, such as episodic memory, working memory and creative problem solving. This study was conducted to evaluate the relationship between mood states and cognitive functioning among older adults with Mild Cognitive Impairment (MCI). This study involved 12 male and 37 female subjects from Klang Valley aged 60 year old and above. MCI was defined based on criteria proposed by Peterson. Cognitive functions of the subjects were accessed using Mini Mental State Examination (MMSE), Rey Auditory Verbal Learning Test (RAVLT), Digit Span, Digit Symbol Substituition Test (DSST) and Visual Reproduction; while mood states including tension, depression, anger, vigour, esteem related affect, fatigue and confusion were accessed using Profile of Mood States (POMS) questionnaire. Total positive subscales score, total negative subscales score and total mood disturbance (TMD) were also calculated. There were significant positive correlations between tension (r = 0.325, p = 0.30), vigour (r = 0.235, p = 0.036), esteem related affect (r = 0.316, p = 0.034) and total positive subscales score (r = 0.307, p = 0.040) with verbal episodic memory as measured using RAVLT fifth trial. In addition, positive correlations were also observed between vigour (r = 0.228, p = 0.035) and total positive subscales score (r = 0.237, p = 0.025) with DSST. After adjusted for confounding factors, subjects who scored higher in esteem related affect (Adjusted OR = 0.390, 95% CI [0.069-0.711], p = 0.019) and tension (Adjusted OR = 0.253, 95% CI [0.075-0.431], p = 0.007) had better verbal episodic memory. Subjects who have higher total positive subscales score were also had faster processing speed (OR = 0.856, 95% CI [0.099-1.614], p = 0.028). However after adjusted for confounding factors, the relationship was not significant (Adjusted OR = 0.383, 95% CI [-0.247-1.013], p = 2.226). Older adults with MCI who had a more positive mood tend to have a better short-term verbal memory and faster processing speed.

    This paper aims to explore the readi n ess of takaful operators to integrate waqf as part of their product feature by assessing on the components of as proposed in the New Product Development Model: marketing supports; formalized development process and top management supports. Questionnaire w a s employed in this survey and takaful operators’ employees who involved in product development were selected such as actuaries, business development managers and their executives. Unexpectedly, several takaful operators withdrew from participating in the s urvey (it was last minute) which is limitation in this study. Accordingly, it caused the use of non parametric tests in this study since the data is not normally distributed. Spearman rank correlation shows that formalized development process is the sig n ificant factor that influenced the readiness of the takaful operators to integrate waqf in their products. However, the other two independent variables which are marketing supports and top management supports depicted insignificant result. Nevertheless, t h e findings were still able to provide insights on the integration of waqf by takaful operators as their latest products’ feature.

    This is a cross sectional study conducted in July 2010 at the International Medical University, Seremban, Malaysia. The objective of this study was to ascertain the relationship between working memory capacity of final MBBS medical students using the digit span backward test and their academic achievement based on the total score at the modified
    essay questions (MEQ) which was the principal component of the theory examination. Seventy eight final year medical students were recruited,41 (52.6%) were females and remaining 37 (47.4%) were males. Working memory capacity was measured by digit span backward test (DSBT) which ranged from3 to 8 digits. The mean digit score was 6.6 ± 1.1 falling under the category of ‘above average’ score. There was no significant difference between working memory capacity and gender (p>0.05). There was no significant difference in the MEQ mean score and the different categories of working memory capacity (p>0.05).
    The DBST shows uniformity in working memory adequate to pass the modified essay questions. Medical students appear to use encoding and retrieval process in problem solving based on functionality and pattern recognition in tackling the problems in the MEQ.

    Objective. To conduct an innovative workshop activity using plastic building blocks to create a student-centric environment that encouraged development of creative thinking skills and self-reflection in undergraduate pharmacy students.Methods. Students were randomly allocated into small groups of four and assigned the role of either architect or team builder and tasked with creating a LEGO robot. Students were not allowed to speak during the activity. The architect was tasked with providing instructions to team builders on how to build the robot using nonverbal communication. After completion of the task, each group was asked to reflect on the exercise and share what they learned with the entire class. These discussions were video recorded and thematically analyzed.Results. The metaphorical models that students built served as a basis for discussion, problem-solving, and decision-making. Students described how this activity enabled them to mentally and visually link abstract concepts, such as decision-making and problem-solving, to actual practice. Three themes were identified from the qualitative study: thinking with hands, listening with eyes; linking theory to practice; and learning through reflection.Conclusion. This activity offered a non-confrontational way to support communication and the learning process. The use of an interactive game can be a useful teaching strategy to create an active-learning environment, helping pharmacy students improve their social and cognitive skills, such as decision-making, problem-solving, and communication.

    The purpose of this article is to discuss the strengths and limitations of two teaching strategies currently utilized
    in Diploma in Nursing, in Malaysia. The diploma was started in 1994 with a 3 years duration of study. It also
    requires certificates of qualification from the Malaysian Quality Agency (MQA) and the Malaysian Board of
    Nursing.
    Teaching strategies of individual teachers differ according to their teaching styles and generalized lesson plans,
    which include structures, instructional objectives, outlines of teaching and learning tactics, and other
    accessories needed to implement the strategies. A strategy does not necessarily follow a single track all the
    time, but changes according to the demands of the situations such as the age, level, needs, interests and abilities
    of the students. Thus, strategy is a method that is more comprehensive. It is directional in nature and refers to
    the goal oriented activities of the teacher. Hence, it resembles science rather than arts.
    Lecture and simulation methods are the best teaching strategies for nursing students in Malaysia. The lecture
    method allows clarification on difficult concepts, organizes thinking, and promotes problem solving attitudes,
    whereas simulation provides students with the opportunity for proper social, emotional and intellectual
    development. Moreover, students are highly motivated by educational simulation, for they enjoy the learning
    process while participating in it.

    Quality Function Deployment (QFD) is a structured methodology that uses customer and technical
    requirements for designers and manufacturers to provide better products. Many researchers combine or
    integrate the technique of QFD with other methodologies such as Theory Inventive of Problem Solving
    (TRIZ) or Design for Manufacture and Assembly (DFMA) to optimise product design innovation and
    improvement. The combined methodologies are even used to solve process problems. Initial literature
    review of the application of stand-alone QFD poised several problems. Combining QFD with other
    techniques, such as TRIZ and DFMA, has helped to address these issues and forms the basis of future
    research. The integrated methods can solve main contradictory problems more precisely from product
    demand analysis to product design, production and application. Review work of the literature, specifically
    that on research and development of QFD, TRIZ and DFMA, showed that the said methodologies have
    been widely and successfully implemented in several practical applications such as resolving conflicts
    between customer and technical/engineering requirements and reducing production cost. This review work
    provides an in-depth analysis of identifying and finding issues of strengths, weaknesses and outcomes
    of the QFD when combined with TRIZ and also of QFD integrated with DFMA.

    Value Co-Creation (VCC) plays a major role in engaging knowledgeable individuals in a community via innovation, problem solving, and new service/product development. This study investigates the personal factors that influence individuals' engagement in value co-creation in Higher Education Institutions (HEIs) through the use of online platforms. Some higher education institutions have successfully established or used appropriate online platforms, such as online forums, web applications, and mobile applications to engage their community in ideation or crowdsourcing as a part of the value co-creation process. On the other hand, some HEIs have failed to engage their community in value co-creation activities, and even if they managed to engage some individuals in value co-creation once, they failed to sustain these individuals' engagement in value co-creation using online platforms. Using the Stimulus Organism Response (S-O-R) framework, this study examines the relationship between relevant personal factors (commitment and knowledge self-efficacy) and other motivational factors that provide perceived benefits with value co-creation engagement. Data was collected from 308 respondents at five Malaysian research universities. The software analysis tool Smart PLS is used for data analysis and validation. The results demonstrate that personal factors and perceived benefits as a motivational factor has a significant effect on individual engagement in value co-creation. However, the significance of these findings varies from one individual to another. The implications of these findings are discussed.

    Studies have consistently shown that childhood maltreatment is a significant risk factor for the development of drug addiction across human lifespan. Yet, little is known about the prevalence of childhood maltreatment history among drug addicts in Malaysia. The dataset presented in this article provides demographic information on 200 drug addicts recruited from two rehabilitation centres in Malaysia, the prevalence of different types of childhood maltreatment history and the correlation between all types of maltreatments. Analyses of the data can provide insights into the prevalence of maltreatment history and development of drug addiction, therefore indispensable for mental health professionals designing appropriate interventions for the drug addicts. The data can also provide baseline data for comparative studies in terms of childhood maltreatment history and drug addiction across different countries.

    OBJECTIVES: To study the impact of open and closed book formative examinations on pharmacy students' learning approach and also to assess their performance and perception about open book (OB) and closed book (CB) systems of examination.

    METHODS: A crossover study was conducted among Year 1 and Year 2 pharmacy students. Students were invited to participate voluntarily for one OB and one CB online formative test in a chemistry module in each year. Evaluation of their learning approach and perception of the OB and CB systems of examination was conducted using Deep Information Processing (DIP) questionnaire and Student Perception questionnaire respectively. The mean performance scores of OB and CB examinations were compared.

    RESULTS: Analysis of DIP scores showed that there was no significant difference (p > 0.05) in the learning approach adopted for the two different examination systems. However, the mean score obtained in the OB examination was significantly higher (p < 0.01) than those obtained in the CB examination. Preference was given by a majority of students for the OB examination, possibly because it was associated with lower anxiety levels, less requirement of memorization, and more problem solving.

    CONCLUSION: There is no difference in deep learning approach of students, whether the format is of the OB or CB type examinations. However, the performance of students was significantly better in OB examination than CB. Hence, using OB examination along with CB examination will be useful for student learning and help them adapt to growing and changing knowledge in pharmacy education and practice.

    In this present study, microalgal phycobiliproteins were isolated and purified via potential biphasic processing technique for pharmaceutical as well as food applications. The algal pre-treatment techniques were studied to enhance the yield of microalgal phycobiliproteins from the biomass. The proposed methods were optimised to obtain the best recovery yield of phycobiliproteins that can be isolated from the biomass. The phycobiliproteins were further purified using liquid biphasic system. The results showed that microalgal phycobiliproteins of high purity and yield was achieved using sonication treatment (20% power, 50% duty cycle and 7 min of irradiation time) with the biphasic system, where the purification fold of 6.17 and recovery yield of 94.89% was achieved. This work will provide insights towards the effective downstream processing of biomolecules from microalgae.
