Searching for meaning: The mediating role of work engagement in the relationship between meaningful work and turnover intention of Millennials

The highest trends in employee turnover in companies are found in the Millennial generation. This trend is expected to continue to increase every year. This study aims to see how meaningful work influences the intention to leave the company through the role of work engagement as a mediator in the Millennial Generation sample. This research was conducted on 446 Millennial generation employees from various types of companies using convenience sampling methods. The instruments used in this study were Work as Meaning Inventory, Utrecht Work Engagement Scale-9, and Turnover Intention Scale. Based on mediation analysis, work engagement significantly acts as a mediator of the relationship between meaningful work and the intention to leave the company among millennial workers. Hopefully, the findings of this study can provide information for organizations to promote meaningful work and work engagement to increase the willingness of Millennial Generation employees to stay longer in their companies or organizations today

Searching for Factors Contributing to Students’ Intention to Become a Leader: Internal Factors vs. Influence from Others

Leadership development within universities in Indonesia is still lacking, even though it is important as a starting point to develop future leaders. This study is aimed at exploring factors which might affect a students’ intention to become a leader in a student organization, namely, attitude toward student leadership, subjective norms, perceived behavioral control, and leadership self-efficacy. Second- and third-year students (N = 286) from various faculties in a state university filled in a paper-based questionnaire containing newly constructed measurements, based on the theory of planned behavior by Ajzen and the theory of self-efficacy by Bandura. Data analysis using hierarchical multiple regression showed that only the subjective norms were related to the students’ intention to lead student organizations (β = .45, p < .01). This result implied that student organizations should also consider the potential leaders’ peers, families, and significant others to persuade them to become leaders. Other implications were discussed further

Searching for meaning: The mediating role of work engagement in the relationship between meaningful work and turnover intention of Millennials

The trend of employees leaving companies is highest in the millennial generation, and is expected to continue to increase year on year. This study aims to ascertain how the meaningfulness of work affects the intention to leave through the role of work engagement as a mediator in the millennial generation sample studied. The research was conducted on 446 millennial generation employees (aged 20-37) working in various types of companies in Indonesia, using the convenience sampling method. The instruments used in the research were the Work as Meaning Inventory, Utrecht Work Engagement Scale-9, and the Turnover Intention Scale. Based on the mediation analysis, work engagement significantly acts as a mediator in the relationship between the meaningfulness of work and the millennial generation’s intention to leave their company (= -0.071, SE = 0.012, LLCI = -0.094, ULCI = -0.047). It is hoped that the findings from the study will provide information for organizations on promoting meaningful work and work engagement and thus increasing the desire of millennial generation employees to stay longer in their company or organization

Airborne particulate matter monitoring in Kenya using calibrated low-cost sensors [final revised article]

East African countries face an increasing threat from poor air quality stemming from rapid urbanization, population growth, and a steep rise in fuel use and motorization rates. With few air quality monitoring systems available, this study provides much needed high temporal resolution data to investigate the concentrations of particulate matter (PM) air pollution in Kenya. Calibrated low-cost optical particle counters (OPCs) were deployed in Kenya in three locations: two in the capital Nairobi and one in a rural location in the outskirts of Nanyuki, which is upwind of Nairobi. The two Nairobi sites consist of an urban background site and a roadside site. The instruments were composed of an AlphaSense OPC-N2 ran with a Raspberry Pi low-cost microcomputer, packaged in a weather-proof box. Measurements were conducted over a 2-month period (February–March 2017) with an intensive study period when all measurements were active at all sites lasting 2 weeks. When collocated, the three OPCN2 instruments demonstrated good inter-instrument precision with a coefficient of variance of 8.8 ± 2.0 % in the fine particle fraction (PM2.5). The low-cost sensors had an absolute PM mass concentration calibration using a collocated gravimetric measurement at the urban background site in Nairobi. The mean daily PM1 mass concentration measured at the urban roadside, urban background and rural background sites were 23.9, 16.1 and 8.8 µg m−3 , respectively. The mean daily PM2.5 mass concentration measured at the urban roadside, urban background and rural background sites were 36.6, 24.8 and 13.0 µg m−3, respectively. The mean daily PM10 mass concentration measured at the urban roadside, urban background and rural background sites were 93.7, 53.0 and 19.5 µg m−3, respectively. The urban measurements in Nairobi showed that PM concentrations regularly exceed WHO guidelines in both the PM10 and PM2.5 size ranges. Following a “Lenschow”-type approach we can estimate the urban and roadside increments that are applicable to Nairobi (Lenschow et al., 2001). The median urban increment is 33.1 µg m−3 and the median roadside increment is 43.3 µg m−3 for PM2.5. For PM1, the median urban increment is 4.7 µg m−3 and the median roadside increment is 12.6 µg m−3. These increments highlight the importance of both the urban and roadside increments to urban air pollution in Nairobi. A clear diurnal behaviour in PM mass concentration was observed at both urban sites, which peaks during the morning and evening Nairobi rush hours; this was consistent with the high roadside increment indicating that vehicular traffic is a dominant source of PM in the city, accounting for approximately 48.1 %, 47.5 % and 57.2 % of the total PM loading in the PM10, PM2.5 and PM1 size ranges, respectively. Collocated meteorological measurements at the urban sites were collected, allowing for an understanding of the location of major sources of particulate matter at the two sites. The potential problems of using low-cost sensors for PM measurement without gravimetric calibration available at all sites are discussed. This study shows that calibrated low-cost sensors can be successfully used to measure air pollution in cities like Nairobi. It demonstrates that low-cost sensors could be used to create an affordable and reliable network to monitor air quality in cities

Demonstrating PM2.5 and road-side dust pollution by heavy metals along Thika superhighway in Kenya, sub-Saharan Africa

This study assessed the level of heavy metal in roadside dust and PM2.5 mass concentrations along Thika superhighway in Kenya. Thika superhighway is one of the busiest roads in Kenya, linking Thika town with Nairobi. Triplicate road dust samples collected from 12 locations were analysed for lead (Pb), chromium (Cr), cadmium (Cd), nickel (Ni), zinc (Zn), and copper (Cu) using atomic absorption spectrophotometry (AAS). PM2.5 samples were collected on pre-weighed Teflon filters using a BGI personal sampler and the filters were then reweighed. The ranges of metal concentrations were 39–101 μg/g for Cu, 95–262 μg/g for Zn, 9–28 μg/g for Cd, 14–24 μg/g for Ni, 13–30 μg/g for Cr, and 20–80 μg/g for Pb. The concentrations of heavy metals were generally highly correlated, indicating a common anthropogenic source of the pollutants. The results showed that the majority of the measured heavy metals were above the background concentration, and in particular, Cd, Pb, and Zn levels indicated moderate to high contamination. Though not directly comparable due to different sampling timeframes (8 h in this study and 24 h for guideline values), PM2.5 for all sites exceeds the daily WHO PM2.5 guidelines of 25 μg/m3. This poses a health risk to people using and working close to Thika superhighway, for example, local residents, traffic police, street vendors, and people operating small businesses. PM2.5 levels were higher for sites closer to Nairobi which could be attributed to increased vehicular traffic towards Nairobi from Thika. This study provides some evidence of the air pollution problem arising from vehicular traffic in developing parts of the world and gives an indication of the potential health impacts. It also highlights the need for source apportionment studies to determine contributions of anthropogenic emissions to air pollution, as well as long-term sampling studies that can be used to fully understand spatiotemporal patterns in air pollution within developing regions
