The Impact

Time-activity patterns are an essential part of personal exposure assessment to various environmental factors. People move through different environments during the day and they have different daily activity patterns which are significantly influenced by individual characteristics and the residential environment. In this study, time spent in different microenvironments (MEs) were assessed for 125 participants for 7 consecutive days to evaluate the impact of individual characteristics on time-activity patterns in Kaunas, Lithuania. The data were collected with personal questionnaires and diaries. The global positioning system (GPS) sensor integrated into a smartphone was used to track daily movements and to assess time-activity patterns. The study results showed that behavioral and residential greenness have a statistically significant impact on time spent indoors. These results underline the high influence of the individual characteristics and environmental factors on time spent indoors, which is an important determinant for exposure assessment and health impact assessment studies.

The Impact

Sensor technology has enabled the development of portable low-cost monitoring kits that might supplement many applications in conventional monitoring stations. Despite the sensitivity of electrochemical gas sensors to environmental change, they are increasingly important in monitoring polluted microenvironments. The performance of a compact diffusion-based Personal Exposure Kit (PEK) was assessed for real-time gaseous pollutant measurement (CO, O3, and NO2) under typical environmental conditions encountered in the subtropical city of Hong Kong. A dynamic baseline tracking method and a range of calibration protocols to address system performance were explored under practical scenarios to assess the performance of the PEK in reducing the impact of rapid changes in the ambient environment in personal exposure assessment applications. The results show that the accuracy and stability of the ppb level gas measurement is enhanced even in heterogeneous environments, thus avoiding the need for data post-processing with mathematical algorithms, such as multi-linear regression. This establishes the potential for use in personal exposure monitoring, which has been difficult in the past, and for reporting more accurate and reliable data in real-time to support personal exposure assessment and portable air quality monitoring applications.

The Individual

Few studies have evaluated the benefits of reporting back participatory environmental monitoring results, particularly regarding participant motivation toward behavioural modification concerning workplace heat exposure. This study evaluated the individual data report-back for geo-located environmental temperature and time activity patterns in grounds maintenance crews in three geographic regions across the South-eastern United States. Surveys collected information on worker interpretation of their results and intended action(s) to reduce heat exposure. Worker response was highly positive, especially among more experienced workers who expressed a greater willingness to modify personal behaviour to reduce heat stress. Individual-level report-back of environmental data is a powerful tool for individuals to understand and act on their personal exposure to heat.

<p>The apparatus performance is a fundamental problem affecting the organizational performance of West Sulawesi Province Government. Many factors affect it, both individual characteristics and organizational, especially commitment, leadership, compensation and job satisfaction. This study analyzes the effect of organizational commitment, leadership and compensation on job satisfaction and the impact on apparatus performance. The study was conducted on 358 respondents of Government apparatus in West Sulawesi Province. The data was collected by five point Likert scale and analyzed by Structural Equation Model (SEM). The study results found that commitment and leadership affect on job satisfaction and apparatus performance. While compensation only affects job satisfaction and does not affect on performance apparatus.</p>

PurposeThe purpose of the research is to conduct an exploratory investigation of the material handling activities of an Italian logistics hub. Wearable sensors and other smart tools were used for collecting human and environmental features during working activities. These factors were correlated with workers' performance and well-being.Design/methodology/approachHuman and environmental factors play an important role in operations management activities since they significantly influence employees' performance, well-being and safety. Surprisingly, empirical studies about the impact of such aspects on logistics operations are still very limited. Trying to fill this gap, the research empirically explores human and environmental factors affecting the performance of logistics workers exploiting smart tools.FindingsResults suggest that human attitudes, interactions, emotions and environmental conditions remarkably influence workers' performance and well-being, however, showing different relationships depending on individual characteristics of each worker.Practical implicationsThe authors' research opens up new avenues for profiling employees and adopting an individualized human resource management, providing managers with an operational system capable to potentially check and improve workers' well-being and performance.Originality/valueThe originality of the study comes from the in-depth exploration of human and environmental factors using body-worn sensors during work activities, by recording individual, collaborative and environmental data in real-time. To the best of the authors' knowledge, the current paper is the first time that such a detailed analysis has been carried out in real-world logistics operations.

Background: Brazil´s dam-building plans in Amazonia imply substantial environmental and social impacts. This study evaluates the relationship between social, environmental, and economic aspects and impacts on the health status of the population of Rondônia, Brazil, due to the implementation of the Jirau and Santo Antônio hydroelectric dams. Methods: A qualitative and retrospective Health Impact Assessment (HIA) is used to focus the study objectives. The information is arranged in a structured diagram that enables an outside reviewer to assess the aspects/impacts relationship derived from the construction of the dams. This comes with outline recommendations for health risk management that can orient national health authorities. We selected a narrative review synthesis as the most appropriate approach for the study. Results: The diagram network was built making it possible to analyse the impact changes caused by this enterprise in the health sector. Additionally, the model will serve in the implementation of a complete HIA approach in an attempt to quantitatively map the impacts and to propose recommendations. Conclusion: This effort is very important for highlighting the priorities in the public policy decision-making process, serving as a basis for the Brazilian Health System.
