Objectives The aim of this paper is to respond to the commentary of Peter K. Smith, Christina Salmivalli, and Helen Cowie ( Journal of Experimental Criminology , 2012 ), who raise concerns regarding some of the findings of our systematic review and meta-analyses on the effectiveness of bullying prevention programs. They target three findings in particular: (1) the significant association of ‘Work with Peers’ with greater victimization; (2) the significant association of ‘Disciplinary Methods’ with less bullying perpetration and victimization; and (3) the age variations in effectiveness, suggesting larger effect sizes for older age students. Methods We provide explicit information and further detailed analyses on the relationship between these features and effect sizes, including heterogeneity tests and results from weighted regression analyses. For one element in particular (work with peers), we present further research findings from evaluations conducted by Smith, Salmivalli, and Cowie (and also findings from other independent researchers) which support our previous findings. New within-program analyses to examine variations in effect sizes with the age of the students are also presented. Results Evaluations conducted by Smith, Salmivalli and Cowie (and by other independent researchers) indicate the same research conclusions: although peer support schemes appear effective based on attitudinal surveys , these schemes are not related to actual levels of bullying or victimization and, in fact, are quite often related to an increase in bullying and victimization. Our definition of ‘disciplinary methods’ did not include the zero-tolerance approach or any type of harsh discipline as suggested in the commentary. In all relevant cases, ‘disciplinary methods’ included sanctions within a warm and loving framework, following the Olweus bullying prevention guidelines. While most programs that utilized firm disciplinary methods were inspired by Olweus, the relationship between disciplinary methods and less victimization was not driven by the Olweus program (which was not related to the victimization effect size). Larger effect sizes (i.e. reductions in bullying and victimization) for programs implemented with older students is a robust result also found in a more recent systematic review regarding the effects of anti-bullying programs on bystander intervention. In within-program analyses, most results suggested that effect sizes were greater for younger students, but these results were driven by the less controlled evaluations. The most controlled evaluation (randomized experiment) provided the opposite result. Conclusions More research is clearly needed on the effectiveness of bullying prevention programs with students of different ages, and we also recommend randomized experiments to assess the importance of different intervention components.

Over the last decades many OECD countries have implemented green quotas, feed-in tariffs, or feed-in premiums to promote electricity production from renewable energy sources (RES-E). More recently, these RES-E policies are overlaid with emission caps to reduce CO 2 emissions. In this paper we investigate how emission caps change the electricity market outcome of pre-existing support schemes for renewable electricity production: with a green quota RES-E production declines, while it remains constant for feed-in tariffs, and expands for feed-in premiums; across all three RES-E policies an emission cap drives up the consumer electricity price with the price increase being lowest for the case of feed-in premiums; the economic adjustment cost to emission caps on the other hand turn out to be highest for pre-existing feed-in premiums, followed by feed-in tariffs and green quotas.

The COVID-19 crisis presents manifest threats for entrepreneurs since their business survival is often directly at stake given the alarming economic downturn. This existential threat, together with their crucial role in the economy, is the reason for the plethora of public financial support schemes being implemented throughout the entire world. However, support schemes for mental health are lacking. We aim to investigate, first, whether burnout levels have increased during the crisis and, second, whether burnout levels during the COVID-19 crisis depend on the threat of becoming ill, having to stay at home due to the lockdown, and/or having to file for bankruptcy due to the economic downturn. We do so using seven data sets of French entrepreneurs with a temporal comparison of averages and two data sets of French entrepreneurs with a cross-sectional analysis of individuals. Our findings show that indeed, the risks of burnout have increased during the pandemic and that the threat of bankruptcy is the dominant threat. As an increasing number of studies in the entrepreneurship literature indicate that entrepreneurs’ mental health influences their activities, as well as the growth and sustainability of their ventures, our study is important and timely in its contribution, as it takes a close look at the perception of burnout in general and more specifically during the COVID-19 pandemic. The risk of burnout in French entrepreneurs has increased significantly during the COVID-19 pandemic, which calls for not only financial support but also other forms of support. The COVID-19 pandemic presents many threats for entrepreneurs since their business survival is often directly at stake. These threats are not just financial but also related to health, such as the threat of burnout. The findings of our study show that for French entrepreneurs, the threat of burnout increased after the arrival of the COVID-19 pandemic. This finding raises the question whether this outcome is due to the threat to health, the effects of the lockdown, or the threat of bankruptcy. It appears that all three factors play important roles, although the financial threat is the dominant threat. These findings call for the extension of entrepreneurial support systems beyond the financial area by also involving an “entrepreneurship care” aspect, which includes telephone support, webinars, and mental help facilities.

Most existing renewables support schemes distort location and dispatch decisions. Many impose unnecessary risk on developers, increasing support costs. Efficient policy sets the right carbon price, supports capacity not output, ensures efficient dispatch and location. The EU bans priority dispatch and requires market-based bidding, but does not address the underlying problem that payment is conditional on generation, amplifying incentives to locate in windy/sunny sites. This article identifies the various distortions and proposes an auctioned contract to address location and dispatch distortions: a financial Contract for Difference (CfD) with hourly contracted volume proportional to local renewable output/MW, with a life specified in MWh/MW, with long-term transmission contracts based on predicted output-weighted actual or simulated nodal prices. This yardstick CfD delivers efficient dispatch. It assures but limits the total subsidy. It does not over-pay for windy/sunny sites. The revenue assurance allows high debt:equity, dramatically lowering the subsidy cost.

The study investigates the role of market-based finance and public financial support in aiding scaling up by European SMEs. First, we analyse the impact of public loan guarantee schemes on firms’ access to market-based instruments. Second, we study whether firms’ access to market-based finance and the use of public grants boost a firm’s (ex post) growth. The analysis is based on a unique and original dataset of about 31,000 Eurozone firms in the 2009–2020 period. The study finds that firms’ access to market-based finance is (i) driven positively by the previous use of public financial support schemes and (ii) has a positive effect on subsequent growth. In particular, SMEs display relatively higher growth in fixed assets, while for large firms, growth is mainly driven by current assets. Moreover, SME issuers using public grants achieve significantly stronger growth than comparable firms.

Social support is broad term encompassing a variety of constructs, including support perceptions (perceived support) and receipt of supportive behaviors (received support). Of these constructs, only perceived support has been regarded as consistently linked to health, and researchers have offered differing assessments of the strength of the received‐perceived support relationship. An overall estimate of the received‐perceived support relationship would clearly further the dialogue on the relationship between received and perceived support and thus assist in the theoretical development of the field. This study evaluated all available studies using the Inventory of Socially Supportive Behaviors (ISSB; Barrera, Sandler, & Ramsey, 1981, American Journal of Community Psychology, 9, 435–447) and any measure of perceived social support. Using effect sizes from 23 studies, we found an average correlation of r = .35, p < .001. Implications of this estimate for further development of models of social support as well as interventions to enhance social support are discussed.

Solar energy is one of the most important renewable energy sources in Europe offering new possibilities to generate electricity and heat. In this context, the study provides accurate information about researches that characterize the solar resource and investigates the potential of solar energy in European countries. The analysis is also focused on the current status of market development including photovoltaic capacity, electricity production from solar photovoltaic power, solar thermal capacity and concentrated solar power plants in operation. The final part of the paper covers the support schemes and programmes on solar energy used in Europe.

The roof of coal seams are mostly soft rock with weak cementation. To further study the mechanical characteristics and deformation control scheme of the roadway with weakly cemented siltstone as roof, this paper took Linchang coal mine as the research background and adopted field investigation methods, laboratory experiments, and theoretical analysis. Using a scanning electron microscope, it is found that the weakly cemented siltstone is composed of coarse-grained minerals with a high degree of pore development. According to the analysis, the instability factors of weakly cemented siltstone roadway include the late diagenetic age of rock, the low mechanical strength of rock, and the change of surrounding rock properties by pouring water. The selection of grouting reinforcement materials was studied in detail. The test results show that cement-bonded specimens’ strength is lower than that of Marithan polyurethane cement specimens in general. The combined support scheme based on grouting reinforcement is put forward. Field monitoring data show that the designed support scheme can effectively control the surrounding rock deformation of weakly cemented siltstone roadway.

In 2018, the European Union (EU) adopted a recast of the Renewable Energy Directive (RED), setting the framework for a common EU-wide 2030 target of 32.5% renewables in final energy consumption, for which Member States shall set national contributions. To address the disparities in national targets, the EU introduced three cooperation mechanisms: statistical transfers, joint support schemes, and joint projects. This paper provides an assessment of the utilization of cooperation mechanisms by Member States to meet the 2020 renewable energy target, offering recommendations for the RED III implementation. It analyzes the motivations of both buyer and seller countries, examines the patterns observed in concluded agreements, and interprets the dynamics of the market. The research employs a mixed-methods approach, incorporating a literature review, analysis of official statistics and cooperation agreements, and interviews with government representatives involved in implementing these mechanisms. The study reveals areas for improvement and raises questions about the efficacy of the instruments and their alternatives. To enhance the effectiveness of renewable cooperation mechanisms, a more systemic approach is necessary. The proposed new financing mechanism can ensure certainty in financial allocation and support larger joint projects of European significance. Furthermore, it is anticipated that statistical transfers will continue to be utilized due to established bilateral relationships and the need for last-minute adjustments to achieve renewable energy targets. This research provides valuable insights for policymakers and stakeholders in advancing renewable cooperation mechanisms and driving the EU’s progress towards a climate-neutral continent by 2050.

We evaluate German purchase subsidies for battery electric vehicles (BEVs) and plug-in hybrid electric vehicles (PHEVs) using data on new vehicle registrations in Germany during 2015-2022. We account for confounding time trends and interacting EU-level standards using neighboring countries as a control group. We find that 40% of BEV and 25% of PHEV registrations were subsidy-induced. The program had strong distributional effects, with greater uptake in wealthier and greener counties. We estimate implied abatement costs of 870 euro per ton of for BEVs and 2,470 euro for PHEVs, suggesting that policy makers should re-balance support schemes away from PHEVs.
