Reducing greenhouse gas emissions is a highly prevalent goal of public policy in many countries around the world. Convincing people to drive more fuel-efficiently (“eco-driving”) can contribute substantially to this goal and is often an integral part of policy initiatives. However, there is a lack of scientific studies on the effects of individual monetary and non-monetary incentives for eco-driving, especially in organizational settings and with regards to demonstrating causality, e.g., by using controlled experiments. We address this gap with a six months long controlled natural field experiment and introduce a monetary and a non-monetary reward for eco-driving to drivers of light commercial vehicles in different branches of a logistics company. Our results show an average reduction of fuel consumption of 5% due to a tangible non-monetary reward and suggest only a small reduction of the average fuel consumption in the equivalent monetary reward treatment. We find indications that more emphasis on the fun of achieving a higher fuel efficiency, a more emotional response to non-monetary incentives, and a higher frequency of thinking and talking about non-monetary incentives might play a role in the stronger effect of the tangible non-monetary reward. Policy implications for private and public actors are discussed.
While financial citizen participation plays an increasing role in renewable energy, there is a lack of understanding which socio-psychological factors correlate with a decision to privately invest in ...renewable energy. Based on a conceptual model and an extensive literature review, a survey among retail investors of renewable energy projects in Germany was conducted and compared to existing population samples using logistic regressions and factor analysis. This research finds that the typical retail investor in renewable energy in Germany is more likely to be male with a higher income, to have a higher education, and to live in a more rural area compared with the overall population. The typical investor exhibits strong proenvironmental beliefs and behaviors as well as a predisposition for active citizenship. Furthermore, getting a form of non-financial or 'psychic return' from the investment seems to be important for the investment decision. Strategic adaptions for public and private actors to increase retail investment in renewable energy are discussed.
Increasing energy efficiency is a cornerstone of policy initiatives to tackle climate change and increase corporate sustainability. Convincing people to drive more fuel-efficiently (“eco-driving”) is ...often an integral part of these approaches, especially in the transport sector. But there is a lack of studies on the long-term persistence and potential interaction of the effects of incentives and training on energy conservation behavior in general and eco-driving behavior in particular. We address this gap with a twelve months long natural field experiment in a logistics company to analyze the time-dependent and potentially interacting effects of rewards and theoretical training for eco-driving on fuel consumption in a real-world setting. We find an immediate reduction of fuel consumption following the introduction of a non-monetary reward and an attenuation of this effect over time. Theoretical eco-driving training shows no effect, neither short-term nor long-term, highlighting the often neglected necessity to include practical training elements. Contrary to common assumptions, the interaction of incentives and theoretical training does not show an additional reduction effect. Our results demonstrate the difficulty of changing engrained behavior and habits, and underline the need for a careful selection and combination of interventions. Policy implications for public and private actors are discussed.

The Belle II experiment at KEK in Japan considers an upgrade for the vertex detector system in line with the accelerator upgrade for higher luminosity at long shutdown 2 planned for 2028.
One ...proposal for the upgrade of the vertex detector called VTX aims to improve background robustness and reduce occupancy using small and fast pixels. VTX accommodates the OBELIX depleted monolithic active CMOS pixel sensor (DMAPS) on all five proposed layers. OBELIX is specifically developed for the VTX application and based on the TJ-Monopix2 chip initially developed to meet the requirements of the outer layers of the ATLAS inner tracker (ITk).
This paper will review recent tests of the TJ-Monopix2 chip as well as various design aspects of the OBELIX-1 chip currently under development.
Margaret Klem and John Meierhofer were Bavarian immigrants who
arrived in New Jersey in the 1850s, got married, and started a
small farm in West Orange. When John returned from the Civil War,
he was ...a changed man, neglecting his work and beating his wife.
Margaret was left to manage the farm and endure the suspicion of
neighbors, who gossiped about her alleged affairs. Then one day in
1879, John turned up dead with a bullet in the back of his head.
Margaret and her farmhand, Dutch immigrant Frank Lammens, were
accused of the crime, and both went to the gallows, making Margaret
the last woman to be executed by the state of New Jersey. Was
Margaret the calculating murderess and adulteress portrayed by the
press? Or was she a battered wife pushed to the edge? Or was she,
as she claimed to the end, innocent? Murder on the
Mountain considers all sides of this fascinating and
mysterious true crime story. In turn, it examines why this murder
trial became front-page news, as it resonated with public
discussions about capital punishment, mental health, anti-immigrant
sentiment, domestic violence, and women's independence. This is a
gripping and thought-provoking study of a murder that shocked the
nation.
•Biological sex may not represent social identity of transgender people.•Lack of research on transgender identification in forensic anthropology.•Trans-women (male-to-female) may undergo facial ...feminization surgery.•Impact of facial feminization surgeries on craniometric sex assessment.•Evidence of facial feminization surgery is detectable on crania of trans-women.
In the cases of transgender and gender non-conforming people, a description of their physical remains, including biological sex, may have little correlation with their social identity, delaying and often confusing the issue of identification. Some transgender individuals have sought to alter their physical appearance in order to better reflect their gender. One group of surgical modifications for trans-women, or individuals transitioning from MTF (male-to female), is known as facial feminization surgery (FFS) which involves the reduction and contour of the forehead, chin and jaw contour, and rhinoplasty to give trans-women smoother, smaller facial features. The purpose of this research is to examine the impact of FFS on measurement-based methods of cranial sex assessment, such as discriminant function analysis. The goal is to develop guidelines for correctly recognizing and supporting the identification of trans-women. The results of this study demonstrate that evidence of gender can be found in the facial skeletons of MTF transgender individuals who have undergone facial feminization surgery, and that forensic anthropologists should consider individuals who do not fit into the traditional sex binary when assessing the sex of unidentified skeletal remains.

OBJECTIVE: To update the mortality experience of a cohort of 8508 workers with potential exposure to acrylamide at three plants in the United States from 1984-94. METHODS: Analyses of standardised ...mortality ratios (SMR) with national and local rates and relative risk (RR) regression modelling were performed to assess site specific cancer risks by demographic and work history factors, and exposure indicators for acrylamide and muriatic acid. RESULTS: For the 1925-94 study period, excess and deficit overall mortality risks were found for cancer sites of interest: brain and other central nervous system (CNS) (SMR 0.65, 95% confidence interval (95% CI) 0.36 to 1.09), thyroid gland (SMR 2.11, 95% CI 0.44 to 6.17), testis and other male genital organs (SMR 0.28, 95% CI 0.01 to 1.59), and cancer of the respiratory system (SMR 1.10, 95% CI 0.99 to 1.22); however, none was significant or associated with exposure to acrylamide. A previously reported excess mortality risk of cancer of the respiratory system at one plant remained increased among workers with potential exposure to muriatic acid (RR 1.50, 95% CI 0.86 to 2.59), but was only slightly increased among workers exposed or unexposed to acrylamide. In an exploratory exposure-response analysis of rectal, oesophageal, pancreatic, and kidney cancer, we found increased SMRs for some categories of exposure to acrylamide, but little evidence of an exposure-response relation. A significant 2.26-fold risk (95% CI 1.03 to 4.29) was found for pancreatic cancer among workers with cumulative exposure to acrylamide > 0.30 mg/m3.years; however, no consistent exposure-response relations were detected with the exposure measures considered when RR regression models were adjusted for time since first exposure to acrylamide. CONCLUSION: The contribution of 1115 additional deaths and nearly 60,000 person-years over the 11 year follow up period corroborate the original cohort study findings of little evidence for a causal relation between exposure to acrylamide and mortality from any cancer sites, including those of initial interest. This is the most definitive study of the human carcinogenic potential of exposure to acrylamide conducted to date.
