Arab and Malay Students’ Attitudes toward Statistics and Their Learning Styles: A Rasch Measurement Approach

Students’ learning of statistics has been studied from a variety of angles, and this study is no different. The main purpose is to compare the Malay and Arab students’ attitudes toward learning statistics and their learning styles in understanding statistics. A survey questionnaire and face-to-face interview techniques were used to elicit information from 150 students based on the cohort. They were asked about how they learn to solve statistical problems based on Kolb’s four learning cycles: feeling, reflective observation, thinking, and doing. Attitude responses were numerically recorded based on a five-point Likert scale, while preference for learning styles was recorded as 1 (Do and Feel) or 0 (Watch and Think). Both attitude and learning style data were combined and subjected to Rasch analysis. Results show that a majority of the Arab and Malay students have moderate to high positive attitude toward learning statistics. Generally, students from both cultures are classified as the “Accommodating” type with a preference for doing and feeling from the experience of doing statistical problems. Arab students are classified as the “Assimilating” type with a preference for thinking, reflecting, and learning from observation, while Malay students are classified as the “Converging” type with a preference for thinking and doing statistical exercises.

Opening manufacturing flexibility's black box: the unexplored role of internal flexibility

PurposeThe purpose of this paper is to empirically test a research model exploring the complex links between internal and external manufacturing flexibility capabilities (IF and EF) and competitive advantage (CA).Design/methodology/approachA survey approach with responses from 266 Spanish manufacturing firms from different industries was used. Structural equation modelling and SPSS macro PROCESS were used to test the hypotheses.FindingsManufacturing flexibility (MF) is a dual-dimensional concept composed by IF and EF, which are complementary and hierarchical in its development. Contrary to previous assumptions, IF does not always express its final competitive effect through EF, which only partially mediates the IF–CA relationship. Thus, IF and EF independently can positively enhance a firm's CA, being the direct effect of the IF being stronger than EF.Practical implicationsThis study offers practical insights supporting a guide for prioritising flexibility capabilities through the holistic MF implementation, thus assisting managers wishing to formulate MF strategies seeking efficiency and customer value advantages relative to competitors.Originality/valueThe main novelty of this work is to explore for the first time the direct and indirect role of IF on CA, enlarging the assumptions of the flexibility funnel framework (FFF) and the strategic view of MF. The study is also unique due to both the depth and breadth of the investigation of the basis of the use of resource-based theory (RBT) and by employing a recent and comprehensive MF conceptual systematisation to guide the measurement approach.

COVID-19 Vaccinations and the Volatility of Energy Companies in International Markets

The COVID-19 pandemic has elevated both the risk and volatility of energy companies. Can mass vaccinations restore stability within this sector? To answer this question, we investigate stock market data from fifty-eight countries from January 2020 to April 2021. We document that vaccination programs assist in decreasing the volatility of energy stocks around the world. The drop in volatility is statistically and economically significant and robust to many considerations. The observed phenomenon survives a broad battery of control variables; it is also independent of the employed regression model or the volatility measurement approach. Moreover, the effect is not driven by the dynamics of the pandemic itself or the associated government interventions. Finally, we find the influence of vaccinations on energy stock volatility to be more pronounced in developed markets rather than in emerging ones. Our findings bear clear practical implications: policy makers around the world should consider the essential role of vaccinations in the energy sector.

Pembuktian Strategi Pengarusutamaan Gender (PuG): Analisis Capaian Indeks Pemberdayaan Gender di Indonesia

This study aims to prove the Gender Mainstreaming strategy which is analyzed from the achievements of the Gender Empowerment Index from 2010 to 2020. To prove the Gender Mainstreaming strategy, the author uses an index measurement approach from the indicators forming the Gender Empowerment Index which is then analyzed descriptively. It was found that the implementation of the Gender Mainstreaming strategy in Indonesia has not been optimal. The average achievement of the gender empowerment index from 2010 to 2020 was 71.39, which is still far from the perfect ratio of 100. Judging from its forming indicators, it was found that the representation of women in parliament from 2010 to 2020 was still below 30 percent, then women as the professional workforce are still growing at 40 percent which has not yet reached the 50 percent equality level, and the contribution of women's income has experienced an increasing trend which reflects that women have been included in the workforce, but the increase has been slow.

On the combined flow and structural measurements via Robotic Volumetric PTV

This study describes a novel measurement approach for combined flow and structural measurements in wind tunnels using Robotic Volumetric PTV. The measurement approach is based on the application of a particle tracking algorithm on images including flow or structure tracers, where the latter are implemented by means of fiducial markers. The main steps of the measurement procedure comprise the simultaneous acquisition of flow and structure tracers in the same images, the distinction of the tracers leading to separate flow and structure image sets, the application of Lagrangian Particle Tracking and the further post-processing, and recombination of the obtained data. The approach is applied to the fluid-structure interaction between a flexible plate with a span of 1.2 m and a periodic gust. The total measurement volume amounts approximately to 150 liters. A phase-averaged description of the fluid-structure interaction problem is presented, with the focus on the effects of the spatio-temporal averaging of the flow information. The structural displacements obtained from the PTV system are validated against a scanning vibrometer. The phase-averaged displacement of the markers is also analyzed, assessing both the validity of the phase-averaged approach and the physical coherence of their motion with respect to a structural model of the plate. It is found that Robotic Volumetric PTV is suitable for the measurement of large-scale structural displacements, while it should not be used to measure small-scale vibrations. Finally, a visualization of the combined measurement is presented, together with an analysis of the consistency between the measured structure and flow field.

Calculating capital requirements for operational risk

Operational risks have become increasingly important for banks, especially against the background of growing IT dependency and the increasing complexity of their activities. Further-more, the corona pandemic contributed to the increased risk potential. Therefore, banks have to back these risks with own funds. There are currently three measurement approaches for determining the capital requirements for operational risk. In recent years, and especially during the Great Financial Crisis of 2007/2008, however, some of the weaknesses inherent in these approaches have become apparent. Thus, the Basel Committee on Banking Supervision revised the current capital framework. Therefore, this article examines the various measurement approaches, addresses inherent weaknesses and moreover, presents the future measurement approach developed by the supervisory authorities.

The Phantom of the ‘Responsible Consumer’: Unmasking the Intention–Action Gap with an Indirect Questioning Technique

The intention-action gap stands out in research on sustainable consumption for decades. The current research explores the role of socially desirable responding (SDR) in the appearance of this gap by utilising an indirect questioning technique. Two online experiments (n=306 and n=334) demonstrate, in line with most market surveys, that consumers present themselves as highly responsible when being assessed with the standard survey measurement approach (i.e., direct questioning). However, the responses of participants toward the exact same measures of consumers’ social responsibility perceptions and behavioural intentions heavily drop when applying an indirect questioning technique, indicating a substantial overstatement of consumers’ social responsibility perceptions in traditional market surveys. Furthermore, this study provides novel evidence regarding the validity and underlying mechanism of the indirect questioning technique, thereby alleviating long-lasting concerns about this method. Implications for the intention–action gap discussion and consumer ethics research are proposed.
