Charging Strategy

Electric cars sales have been rising almost steadily over the past decade. Uncontrolled charging has recently emerged as the main detrimental factor to this otherwise environmentally friendly and paradigm shifting technology due to the incurred impact on the energy grid. In addition, people are usually hesitant in allowing their vehicles to be controlled by external units; therefore, controlled charging strategies that offer users the option to have some control over their vehicles seems to be a sensible choice moving towards a gasoline-free vehicles market. This work investigated two price-sensitive charging strategies that allowed users to control the charging of their vehicle in order to receive cost benefits. These strategies were of a parametric nature; thus, the analysis focused on providing useful rules of thumb to guide users in choosing the most suitable strategy and the relevant parameters according to their driving profiles. The results show that when driving less than 40 km/h on average and employing a price-sensitive charging strategy with the proposed optimized parameters, electric car users may obtain 30–40% of the running cost reduction.

Abstract Electric cars represent a promising energy-and carbon-efficient alternative to internal combustion engine cars. However, as mobility behaviour is highly habitual, convincing people to switch from conventional cars to electric is challenging. In the following research, which was carried out in the past years in Slovenia, an attempt was made to determine what influences people’s buying habits and what would motivate them to buy an electric car. It appeared that the most relevant factor for not purchasing electric cars is, firstly, its overall too high price, and, secondly, short driving ranges. Different studies, as well as the results of the following research have revealed that there is no single measure which would dramatically increase the demand for electric cars. The solution is to combine different measures or strategies like Top – Down and Bottom – Up, where both the government and car industry should come across.

AbstractThe article contains an analysis of charging electric cars as a way to increase the use of energy produced from a photovoltaic system. A photovoltaic system is described, consisting of two micro installations, with a power output of up to 40 kWp each, supplying two sectors of the building of the Lublin Science and Technology Park. An internet platform for monitoring the operation of a photovoltaic system is presented. Next, an innovative system for monitoring, consumption and production analysis of electric energy in individual building sectors is described. A surplus of energy produced in one of the sectors was found. It was proposed that this excess energy would be used to charge electric vehicles. An analysis of the surplus power generated by the photovoltaic system in excess of the energy consumed by the building sector was used to determine the power available to the wall charger. The surplus of energy produced was used for calculations related to the amount of charging the electric vehicle required and the cost of traveling 100 km. Charging an electric car not only provides a faster return on investment in the installation, but also presents drivers with a very ecological and economical transport solution.

Survey Approach

The link between dairy farm systems and cost of environmental compliance is not always clear. A survey of Waikato dairy farmers was conducted to establish the real (non-modelled) cost of compliance with environmental regulation in the region. Quantitative and qualitative data were gathered to improve understanding of compliance costs and implementation issues for a range of Waikato farm systems. The average oneoff capital cost of compliance determined through a survey approach was $1.02 per kg milksolids, $1490 per hectare and $403 per cow. Costs experienced by Waikato farmers have exceeded average economic farm surplus for the region in the past 5 years. As regulation increases there are efficiencies to be gained through implementing farm infrastructure and farm management practice to best match farm system intensity.

The effectiveness of human rights adjudicative procedures partly, if not most importantly, hinges upon the adequacy of the remedies they grant and the implementation of those remedies. This assertion also holds water with regard to the international and regional monitoring bodies established to receive individual complaints related to economic, social and cultural rights (hereinafter ‘ESC rights’ or ‘socio-economic rights’). Remedies can serve two major functions: they are meant, first, to rectify the pecuniary and non-pecuniary damage sustained by the particular victim, and second, to resolve systematic problems existing in the state machinery in order to ensure the non-repetition of the act. Hence, the role of remedies is not confined to correcting the past but also shaping the future by providing reforming measures a state has to undertake. The adequacy of remedies awarded by international and regional human rights bodies is also assessed based on these two benchmarks. The present article examines these issues in relation to individual complaint procedures that deal with the violation of ESC rights, with particular reference to the case laws of the three jurisdictions selected for this work, i.e. the United Nations, Inter-American and African Human Rights Systems.

While geologists are still considering whether the Anthropocene should be accepted as a formal geological epoch, it is up to us humanists to search for ways making this human era a good one. In this article, I will examine how we can use historical research to provide such tracks based on past regularities or similarities. Positive success stories from the past can at least provide faith that we can do something about our current environmental problems. This investigation is based on two case studies: the Tesla Model S electric car, and the Swedish pulp and paper industry's transition to chlorine-free bleaching. It argues that the sustainability revolution doesn't just share similarities with the quality movement of the 1970s and 1980s, but is essentially a continuation of it. In concordance with previous megatrends, the major benefit of the sustainability revolution will be reaped by countries and companies running ahead of the curve. A new term, 'trail-blazer dependency' is introduced; by setting an example, the first-movers are opening a trail for late-comers to follow.

Prey Attraction

The ability to attract prey has long been considered a universal trait of carnivorous plants. We review studies from the past 25 years that have investigated the mechanisms by which carnivorous plants attract prey to their traps. Potential attractants include nectar, visual, olfactory, and acoustic cues. Each of these has been well documented to be effective in various species, but prey attraction is not ubiquitous among carnivorous plants. Directions for future research, especially in native habitats in the field, include: the qualitative and quantitative analysis of visual cues, volatiles, and nectar; temporal changes in attractants; synergistic action of combinations of attractants; the cost of attractants; and responses to putative attractants in electroantennograms and insect behavioral tests.

Abstract Background The Open Payments Program, as designated by the Physician Payments Sunshine Act is the single largest repository of industry payments made to licensed physicians within the United States. Though sizeable in its dataset, the database and user interface are limited in their ability to permit expansive data interpretation and summarization. Objectives We sought to comprehensively compare industry payments made to plastic surgeons with payments made to all surgeons and all physicians to elucidate industry relationships since implementation. Methods The Open Payments Database was queried between 2014 and 2019, and inclusion criteria were applied. These data were evaluated in aggregate and for yearly totals, payment type, and geographic distribution. Results 61,000,728 unique payments totaling $11,815,248,549 were identified over the six-year study period. 9,089 plastic surgeons, 121,151 surgeons, and 796,260 total physicians received these payments. Plastic surgeons annually received significantly less payment than all surgeons (p=0.0005). However, plastic surgeons did not receive significantly more payment than all physicians (p = 0.0840). Cash and cash equivalents proved to be the most common form of payment; Stock and stock options were least commonly transferred. Plastic surgeons in Tennessee received the most in payments between 2014-2019 (mean $ 76,420.75). California had the greatest number of plastic surgeons to receive payments (1,452 surgeons). Conclusions Plastic surgeons received more in industry payments than the average of all physicians but received less than all surgeons. The most common payment was cash transactions. Over the past six years, geographic trends in industry payments have remained stable.

ObjectivesThe digitalisation of sexual and reproductive health (SRH) services offers valuable opportunities to deliver contraceptive pills and chlamydia treatment by post. We aimed to examine the acceptability of remote prescribing and ‘medication-by-post’ in SRH.Study designAn online survey assessing attitudes towards remote management was distributed in three UK SRH clinics and via an integrated sexually transmitted infection (STI) postal self-sampling service. Logistic regressions were performed to identify potential correlates.ResultsThere were 1281 participants (74% female and 49% <25 years old). Some 8% of participants reported having received medication via post and 83% were willing to receive chlamydia treatment and contraceptive pills by post. Lower acceptability was observed among participants who were: >45 years old (OR 0.43 (95% CI 0.23–0.81)), screened for STIs less than once annually (OR 0.63 (0.42–0.93)), concerned about confidentiality (OR 0.21 (0.90–0.50)), concerned about absence during delivery (OR 0.09 (0.02–0.32)) or unwilling to provide blood pressure readings (OR 0.22 (0.04–0.97)). Higher acceptability was observed among participants who reported: previously receiving medication by post (OR 4.63 (1.44–14.8)), preference for home delivery over clinic collection (OR 24.1 (11.1–51.9)), preference for home STI testing (OR 10.3 (6.16–17.4)), ability to communicate with health advisors (OR 4.01 (1.03–15.6)) and willingness to: register their real name (OR 3.09 (1.43–10.6)), complete online health questionnaires (OR 3.09 (1.43–10.6)) and use generic contraceptive pills (OR 2.88 (1.21–6.83)).ConclusionsPostal treatment and entering information online to allow remote prescribing were acceptable methods for SRH services and should be considered alongside medication collection in pharmacies. These methods could be particularly useful for patients facing barriers in accessing SRH. The cost-effectiveness and implementation of these novel methods of service delivery should be further investigated.

The Health Belief Model

Quitting smoking isn't easy, even with the advent of e-cigarettes. The NHS Stop Smoking Services (SSSs) were established in 2000, and have shown superior results to nicotine replacement alone, but are characterised by low, and dropping, attendance rates. Beneath the highlight figure of a halving of UK smoking prevalence over the past 40 years lies a direct £6 billion cost to the NHS and 80000 deaths each year, as well as recent concern that clinical commissioning groups are not renewing service funding. Given that the ‘health belief model’ is based upon a trigger changing behaviour, what will encourage attendance at SSSs, especially with evidence that smokers underestimate their own personal risk? Gilbert et al randomised over 4000 smokers across almost 100 general practices to receive either a standard generic advertisement of the SSS clinic, or an individually tailored risk letter and invitation to a no-commitment introductory SSS session. The hosting general practitioners (GPs) and SSS advisors were masked to the allocation. The personalised letter more than doubled the odds of attending the SSS, showing that a more proactive approach can help engagement. Interestingly, the intervention was more effective with men, who are typically less likely to attend and set quit dates.

The authors present a detailed case study of the evolution of apprenticeships in German banking over the past two decades to analyze why employers continue to be willing to invest in these programs that provide workers with transferable skills. They explain employers' motivation in terms of two “logics.” Some considerations stemming from the logic of consequences, such as recruitment cost savings and enhanced workplace flexibility, encourage retention of the apprenticeship system. On balance, however, the cost calculus that is at the heart of the logic of consequences would, if unopposed, encourage head-hunting for apprentices trained by other firms, eventually undermining the system. The countervailing logic of appropriateness, however, discourages defections from the system by fostering trust among employers, encouraging new firms to participate in the system, supporting the strong reputational effect associated with training, and creating mechanisms with which banks can have a hand in keeping the system efficient.
