Driving a vehicle above the speed limit is unsafe driving behavior that may cause the occurrence of an accident. Speed limitation can be one way to improve road safety. This study aims to get an illustration of speed limit violation committed by the drivers on the national road segment, and also to investigate the demographic and psychological factors that affect driver behavior in violating the speed limit as stated in the traffic regulation. Speed data collection was carried out at the Bekasi Raya national road in Bekasi, while the demographic and psychological data were collected using questionnaires through online methods. The result of speed measurement using Speed Gun to 30 motorcycles, 30 light vehicles, and 30 heavy vehicles, shows that there are no light or heavy vehicles that drive above the speed limit. Speeding behavior only is indicated by a little number of motorcyclists. From the online survey through the distribution of questionnaires to 102 motorcyclists, it was found that speeding behavior tends to be done when they are in a rush situation. Mengendarai kendaraan di atas batas kecepatan (ngebut) merupakan perilaku mengendara yang berkontribusi terhadap terjadinya kecelakaan..Salah satu cara untuk meningkatkan keselamatan di jalan raya adalah dengan pembatasan kecepatan. Penelitian ini bertujuan untuk mendapatkan gambaran tentang pelanggaran batas  kecepatan yang dilakukan pengemudi di ruas jalan nasional, dan faktor-faktor demografis, serta faktor psikologis yang berperan dalam perilaku pengendara kendaraan bermotor melanggar batas kecepatan yang telah ditentukan oleh peraturan lalu lintas. Pengambilan data kecepatan dilakukan di jalan nasional Bekasi raya, sedangkan data tentang faktor demografis dan psikologis diperoleh melalui penyebaran kuesioner melalui online. Hasil pengukuran kecepatan terhadap 30 sepeda motor, 30 kendaraan ringan, dan 30 kendaraan berat dengan Speed Gun menunjukkan bahwa tidak ada kendaraan ringan maupun kendaraan berat yang mengemudikan kendaraan di atas batas kecepatan. Perilaku ngebut dilakukan oleh sebagian kecil pengendara sepeda motor. Dari survey melalui penyebaran kuesioner terhadap 102 pengendara diperoleh gambaran bahwa perilaku ngebut cenderung dilakukan ketika berada pada situasi tergesa-gesa.

Speeding is one of the risk factors for road traffic crashes and deaths, especially for vulnerable road users. Research shows that increasing vehicle speed by 1 km/h can increase 4% -5% of fatal crashes. However, several other studies show that crashes are caused more by speed dispersion than by average speed vehicles in the traffic. This study aims to determine the effect of speed limit violations on the rate of a motorcycle crash on the national road in Bandung City. Although the proportion of motorcycles that violates the speed limit is quite high (40%), it turns out the result of this study indicates that the rate of motorcycle crash does not seem to be affected by the proportion of motorcycle in the traffic that violates the speed limit. Crashes involving motorcycles are more prevalent in the highest flow period than in the free flow conditions where the proportion of motorcycle that violates the speed limit is the highest. Mengendara dengan kecepatan tinggi merupakan salah satu faktor risiko penyebab kecelakaan lalu lintas dan kematian akibat kecelakaan lalu lintas, terutama pada kelompok pengguna jalan rentan. Penelitian menunjukkan bahwa peningkatan kecepatan kendaraan sebesar 1 km/jam dapat meningkatkan 4%-5% kecelakaan fatal. Namun beberapa penelitian lainnya menunjukkan bahwa kecelakaan lebih disebabkan oleh adanya variasi kecepatan di dalam arus dibanding kecepatan rata-rata kendaraan di dalam arus. Penelitian ini bertujuan untuk mengetahui pengaruh pelanggaran batas kecepatan terhadap tingkat kecelakaan sepeda motor di jalan nasional Kota Bandung. Walaupun proporsi sepeda motor yang melanggar batas kecepatan cukup tinggi (40%), ternyata hasil penelitian mengindikasikan bahwa tingkat kecelakaan sepeda motor tampaknya tidak dipengaruhi oleh proporsi sepeda motor di dalam arus yang melanggar batas kecepatan. Kecelakaan yang melibatkan sepeda motor justru lebih banyak terjadi pada kondisi arus tertinggi dalam satu hari dibanding pada kondisi arus lengang dimana proporsi sepeda motor yang melanggar batas kecepatan paling banyak.

Using Data

The presence of satisficers among survey respondents threatens survey data quality. To identify such respondents, Oppenheimer et al. developed the Instructional Manipulation Check (IMC), which has been used as a tool to exclude observations from the analyses. However, this practice has raised concerns regarding its effects on the external validity and the substantive conclusions of studies excluding respondents who fail an IMC. Thus, more research on the differences between respondents who pass versus fail an IMC regarding sociodemographic and attitudinal variables is needed. This study compares respondents who passed versus failed an IMC both for descriptive and causal analyses based on structural equation modeling (SEM) using data from an online survey implemented in Spain in 2019. These data were analyzed by Rubio Juan and Revilla without taking into account the results of the IMC. We find that those who passed the IMC do differ significantly from those who failed for two sociodemographic and five attitudinal variables, out of 18 variables compared. Moreover, in terms of substantive conclusions, differences between those who passed and failed the IMC vary depending on the specific variables under study.

PURPOSE: Trust is vital to all positive relationships. This empirical study explores the effect of three facets of organisational trust (trust in supervisors, in co-workers and in the organisation) on employee commitment in Salalah Mills Co. in the food industry in the Sultanate of Oman. METHODOLOGY: Data were collected via an online survey sent to all employees working in Salalah Mills Co., Oman. The final sample consisting of 102 responses with a response rate of 54 percent were analysed using multiple regression analysis. RESULTS: The findings revealed that two facets of organisational trust (trust in co-workers and trust in supervisors) were found to have a significant positive effect on employee commitment, while trust in the organisation was found to have no significant effect. PRACTICAL IMPLICATIONS: Trust in supervisors and trust in co-workers directly affect employee commitment. Therefore, managers should consider promoting both of these forms of trust to enhance employee commitment. VALUE: Although previous studies have examined the link between organisational trust and employee commitment, a focus on Oman and the food sector has been particularly rare, so this study offers new insights. The findings will help decision-makers on design strategies and policies to improve employee commitment through trust.

In order to reduce operation risk and working intensity in mountainous orchard transportation and to realize optimized control for the mountainous orchard electric-drive monorail transportation system, a mountainous orchard electric-drive monorail transporter control system was designed and developed in this study. The system mainly consists of modules as: manual and remote control, positioning, obstacle avoidance, speed measurement, motor control, electric-magnetic break, and the position limit. The driving speed, current consumption, break control, and battery pack running ability experiments were conducted to test the control system. Results indicated that, the transporter’s driving speed is 0.60~0.58 m/s when it is running on the ground with the load weight from 0 to 100kg. This speed is little affected by the load weight. The transporter’s driving speed is 0.45~0.28 m/s when it is climbing a steep hill with an angle of 39°. That speed is critically affected by the load weight. In further improvements, a shift mechanism will be introduced so that adjustable gear ratio could be achieved thus solve the current overload problem in a full load situation.

In this paper, we propose two models describing the dynamics of heavy and light vehicles on a road network, taking into account the interactions between the two classes. The models are tailored for two-lane highways where heavy vehicles cannot overtake. This means that heavy vehicles cannot saturate the whole road space, while light vehicles can. In these conditions, the creeping phenomenon can appear, i.e., one class of vehicles can proceed even if the other class has reached the maximal density. The first model we propose couples two first-order macroscopic LWR models, while the second model couples a second-order microscopic follow-the-leader model with a first-order macroscopic LWR model. Numerical results show that both models are able to catch some second-order (inertial) phenomena such as stop and go waves. Models are calibrated by means of real data measured by fixed sensors placed along the A4 Italian highway Trieste–Venice and its branches, provided by Autovie Venete S.p.A.

Digital computers that automate manufacturing process are an important aspect for any manufacturing engineers in the modern world. Selection of the programming paradigm (PP), as well as the programming language (PL) that supports it, is crucial to ensure the correct ideas are being used to automate the solution of the problem. In current Malaysian Higher institution practices, various PPs and PLs courses are offered to current undergraduate manufacturing majors. An online survey was deployed to experienced manufacturing engineers from various manufacturing specializations in the industry. Graduates from one of Malaysias public universities, International Islamic University Malaysia (IIUM) have been chosen for this particular study. From the survey, it has been found that almost 80% of the participants agreed that PPs are important for manufacturing graduates. It was found out that 90% of the participants were from intermediate (scale of 3) until poor (scale of 1) to express their ability to explain PPs if asked. Only about 10% are able to explain on PPs (scale of 4 and 5). The study concluded that majority of the manufacturing graduates from IIUM agreed that PP is an important subject to be taught in university. However, it was found the majority of the manufacturing graduates lack the knowledge and understanding of PPs and general PLs.

This study investigates how university students engage with their learning affordances in a contested environment due to the Coronavirus pandemic. This qualitative research employed a case study approach involving 136 participants. Data analysis was conducted using qualitative analysis as a circular process to describe, classify, and perceive the phenomenon and how the learning, affordances, and society were interconnected. The main framework of the research was the theory of affordance and how it was available for university students in their learning environment that changed due to the COVID-19 pandemic. Data were collected in the first semester of 2020 through an online survey on Google form. The findings indicate the importance of the social environment to provide affordance for the students to adjust with them. Four kinds of affordances emerged from the study; internet affordance, assignment affordance, domestic affordance, and distance learning affordance. The role of the social environment is definitive in changing how students manage their affordances.

This study is an attempt to evaluate the effects of media language misusing in comedian programs of Iraqi Kurdish televisions. To achieve this goal, the researchers have done an online survey with 145 TV viewers; as well as analyzing the thematic contents of 12 episodes of the BEZMÎ BEZM program on the KurdMax satellite channel.   Based on the research results; media language misusing in the BEZMÎ BEZM program has negative effects on viewers of this program, despite the fact that the majority of opinions agreed on the definition of this satellite as a Kurdish entertainment channel and the rates of views of its main programs "Great". However, they also agreed that this program on the KurdMax satellite channel has become a popular platform for insults, exchange of accusations, and defamation of certain personalities and groups in society, and a reason for sabotaging the Kurdish language and its methods, producing linguistic and psychological violence and highlighting gender discrimination. In addition to sabotaging the public taste of viewers, lack of respect for their needs, delinquency of adolescents, reducing the value of artistic work etiquette and educational foundations, and underestimating the family and Kurdish culture and its peculiarities. As for the topics presented in this program, the main goal is to make viewers laugh only and to achieve this; they do not hesitate to spread market language and archaic and patriarchal cultures, encourage gender differences of men and women, social and sexual taboos, defame personalities, neglect health guidelines, and violate professional media ethics. All of the above; represents the main identity of the BEZMÎ BEZM program on the KurdMax satellite channel. As a final point, this research has recommended the relevant people and bodies to subordinate such programs in order to review its content based on legal and ethical media standards, laws, and rules of the Kurdish language, along with abiding professional art principles.

New Perspective

The phenomenon of sex has always been novel in every era. In Indonesia, for example, Enny Arrow’s stencil novel has been circulating, which has been named as a legend of Indonesian erotic literature. Along with the development of technology, the existence of stencil novels was replaced by DVDs or VCDs, which then continued with the emergence of various sites providing access to pornography. This difference in phenomena certainly makes the meaning of sex for each individual different. This research will analyze the meaning of sex in the stencil novel by Enny Arrow in the eyes of millennial men. The data analysis will focus on social psychological factors using Normand Holland’s literary reception theory. From the data analysis, it can be concluded that there are different views on sexual relations before and after reading the novel. This research is expected to provide a new perspective on the picture of sexuality for modern humans.
