In Morocco, the construction sector is very dynamic economically, but suffers from weak safety performance. The few available statistics about the rates of occupational injuries and fatalities point to an alarming situation. However, root causes are yet to be identified. To fill this gap in knowledge, we conducted this study using an exploratory approach. Literature review, onsite observations and a survey were conducted to gather information about safety and risk aspects on construction sites. We conducted a series of correlation tests and a regression analysis using IBM SPSS version 20. The results showed that: (a) there is a relatively strong risk perception bias among workers, with an underestimation of risk severity and occurrence probability; (b) risk perception was not found to predict safety behavior; (c) a positive safety climate seems to neutralize the negative impact that high risk tolerance had on safety behavior.

Background/objectives: Rural communities in the United States experience increased disparity of care for both general healthcare services and access to routine vaccines. Previous research has indicated a 40% lower vaccination rate in rural communities, as compared to urban counterparts. Having a better understanding regarding factors influencing lower vaccination rates in rural areas could help public health officials prepare for future vaccination efforts.

To address the difficulty in detecting workers' violation behaviors in electric power construction scenarios, this paper proposes an innovative method that integrates knowledge reasoning and progressive multi-level distillation techniques. First, standards, norms, and guidelines in the field of electric power construction are collected to build a comprehensive knowledge graph, aiming to provide accurate knowledge representation and normative analysis. Then, the knowledge graph is combined with the object-detection model in the form of triplets, where detected objects and their interactions are represented as subject-predicate-object relationship.

Unlicensed taxis seriously disrupt the transportation market order, and threaten passenger safety. Therefore, this paper proposes a method for identifying unlicensed taxis based on travel characteristics. First, the vehicle mileage and operation time are calculated using traffic surveillance bayonet data, and variance analysis is applied to identification indicators for unlicensed taxis.

Anomaly detection is critical in safety-sensitive fields, but faces challenges from scarce abnormal data and costly expert labeling. Time series anomaly detection is relatively challenging due to its reliance on sequential data, which imposes high computational and memory costs. In particular, it is often composed of real-time collected data that tends to be noisy, making preprocessing an essential step.
