CHALLENGES IN DEVELOPING JUNIOR HIGH SCHOOL STUDENTS' COMPUTATIONAL THINKING SKILLS IN MATHEMATICS THROUGH PROBLEM-BASED LEARNING
No full textThis research aims to analyze students' computational thinking abilities in mathematics learning through problem-based learning. A qualitative approach with a case study design was employed. The research was conducted at SMP Negeri 1 Cibinong, Bogor Regency, West Java. The subjects were three ninth-grade students who had studied material on exponents and roots, selected based on the teacher's recommendations. Data were collected through computational thinking tests and interviews. Based on the analysis, it was found that students, despite their teachers implementing problem-based learning, still lacked strong computational thinking skills. The suboptimal implementation of PBL and the students' unfamiliarity with problem-solving contributed to their difficulty in effectively applying computational thinking skills. In conclusion, the use of problem-based learning in mathematics, particularly in the topics of exponents and roots, has not yet enabled students to fully develop computational thinking skills
Corporate governance and cash holdings: the way forward
No full textPurpose This study aims to provide a review of corporate governance and cash holdings because strong corporate governance is necessary for the efficient utilization of firm’s liquid resources such as cash, to minimize the agency cost of high cash holdings and to improve the value of cash. Design/methodology/approach The author provides a literature review of corporate governance and cash holdings through a conceptual and theoretical argument rather than empirical research. Findings The author reviews empirical and theoretical work surrounding key corporate governance variables and identifies avenues for future research. The author finds that corporate governance mechanisms and cash holdings have received much attention during the last two decades. However, the significant role of corporate governance (both country-level and the firm-level) in controlling the entrenched behavior of the managers is discussed separately in the literature. The combined effect of both country-level and the firm-level governance is lacking in the cash holdings literature. Additionally, this study has found that much attention is paid to the developed markets, only a few focused on the developing markets regarding cash holding literature although, the agency problems are high in developing markets. Originality/value The study contributes to the growing literature on corporate governance and cash holdings and provides a further understanding of the role of governance in minimizing the agency cost to increase value by assuring that firms’ assets are used efficiently and productively in the best interests of investors and other stakeholders. In addition, it provides a new idea to the policies maker and future researchers where they need to do more work
Toward Sustainable Internet of Underwater Things: Unmanned Aerial Vehicle-Aided Energy-Efficient Wake-Up Solutions
No full textWith the advancements in underwater wireless communications, Internet of Underwater Things (IoUT) realization is inevitable to enable many practical applications, such as exploring ocean resources, ocean monitoring, underwater navigation, and surveillance. The IoUT network often comprises battery-operated sensor nodes, and replacing or charging such batteries is challenging due to the harsh ocean environment. Hence, the development of an energy-efficient IoUT network becomes vital for improving the network’s lifetime. Therefore, this article proposes unmanned aerial vehicle (UAV)-aided energy-efficient wake-up designs to activate the IoUT nodes on demand and reduce their energy consumption. Specifically, the UAV communicates with water surface nodes, i.e., buoys, to send wake-up signals (WuSs) to activate the IoUT sensor nodes from sleep mode. We present three different technologies to enable underwater wake-up: acoustic, optical, and magnetic induction (MI)-based solutions. Moreover, we verify the significance of each technology through simulations using the performance metrics of received power and lifetime. Also, the results of the proposed on-demand wake-up approach are compared with conventional duty cycling (DC), showing the superior performance of the proposed schemes. Finally, we present some exciting research challenges and future directions.This work was supported in part by the United Arab Emirates University (UAEU) through the UAEU Program for Advanced Research under Grant 12N174.
