The number of e-commerce transactions is increasing worldwide. Deliveries of goods purchased online generate externalities throughout the whole supply chain and, particularly, the increasing concern about the last-mile distribution of goods. The escalating presence of vans in cities contributes to poor air quality, climate change, noise, and congestion. So far, the majority of solutions to address this issue are based on the supply side, such as electric vans, optimizing the routing and pick-up-points, and so forth. Even in other transport sectors, pricing solutions are well known, yet they have not been extended to e-commerce delivery. This paper aims to propose an environmental tax falling on the demand side and equaling the externalities from this activity. The analysis has been particularized for the case of Barcelona. A cost–benefit analysis to assess the impact of such a tax has been carried out. When revenue collection is reinvested in the logistics sector, and for subsidizing electric distribution vehicles, the results indicate that the levying of the tax can generate positive outcomes.

Political parties have long thrived on systematic grassroots mobilization of support. But does traditional partisan bottom-up mobilization still matter in an interconnected digital age turning the world into a `global village'? We address this question by studying the impact of the populist Movimento Cinque Stelle (M5S) on the rejection of the 2016 constitutional referendum in Italy. The movement's unusual practice to coordinate activities on a public event platform provides a unique opportunity to collect the complete event history of a modern political party. We merge this data consisting of over 200'000 geo-coded meetings by 1'000 local chapters with referendum results and individual panel data. Relying on regression, matching, and instrumental variable models, we find a small but consistent effect of M5S activity on the referendum outcome. Our findings demonstrate the continued relevance of bottom-up mobilization and highlight direct democratic means as an influential channel for populist movements.

Background A range of non-contact injuries such as anterior cruciate ligament tear, and patellofemoral pain syndrome are caused by disordered knee joint loading from excessive dynamic knee valgus (DKV). Previous systematic reviews showed that DKV could be modified through the influence of hip strength and ankle range of motion. Therefore, the purpose of this systematic review was to examine the effects of exercise intervention which involved either top-down or bottom-up kinetic chains on minimizing DKV in male and female adults and adolescents, with and without existing knee pain. Methodology Electronic searches were conducted in SAGE, Science Direct, SCOPUS, and Pubmed. The search strategy consisted of medical subject headings and free-text search keywords, synonyms and variations of ‘exercise intervention,’ ‘knee alignment,’ ‘dynamic knee valgus’, ‘knee abduction’ that were merged via the Boolean operator ‘AND’ and ‘OR’. The search was conducted on full-text journals that documented the impact of the exercise intervention program involving either the bottom-up or top-down DKV mechanism on the knee kinematics. Furthermore, exercise intervention in this review should last at least one week which included two or three sessions per week. This review also considered both men and women of all ages with a healthy or symptomatic knee problem. The risk of bias of the included studies was assessed by Cochrane risk assessment tool. The protocol of this review was registered at PROSPERO (registration number: CRD42021219121). Results Ten studies with a total of 423 participants (male = 22.7%, female = 77.3%; adults = 249, adolescents = 123; pre-adolescent = 51) met the inclusion criteria of this review. Seven studies showed the significant effects of the exercise intervention program (range from two weeks to ten weeks) on reducing DKV. The exercise training in these seven studies focused on muscle groups directly attached to the knee joint such as hamstrings and gastrocnemius. The remaining three studies did not show significant improvement in DKV after the exercise intervention (range between eight weeks to twelve weeks) probably because they focused on trunk and back muscles instead of muscles crossing the knee joint. Conclusion Exercises targeting specific knee-joint muscles, either from top-down or bottom-up kinetic chain, are likely to reduce DKV formation. These results may assist athletes and coaches to develop effective exercise program that could minimize DKV and ultimately prevent lower limb injuries.

With regional variations, climate change has a significant impact on water quality deterioration and scarcity, which are serious challenges in developing countries and emerging economies. Often, effective projects to improve water management in the light of climate change are difficult to develop because of the complex interrelations between direct and indirect climate impacts and local perceptions of vulnerabilities and needs. Adaptation projects can be developed through a combination of participatory, bottom-up needs assessments and top-down analyses. Climate change impact chains can help to display the causal chain of climate signals and resulting impacts and thereby establish a system map as a basis for stakeholder discussions. This article aims to develop specific climate change impact chains for the water management sector in rural coastal India that combine bottom-up and top-down perspectives. Case studies from Tamil Nadu and Andhra Pradesh, India, provide a basis for the impact chains developed. Bottom-up data were gathered through a vulnerability and needs assessment in 18 villages complemented with top-down research data. The article is divided into four steps: (1) system of interest; (2) data on climate change signals; (3) climate change impacts based on top-down as well as bottom-up information; (4) specific impact chains complemented by initial climate change adaptation options.

Background/Context Critical education studies tries to make sense of the relationship between education and differential power in an unequal society and to what degree schools impact the social order. A premise in this field is that a fundamental aim of critical education is exposing unequal social, cultural, and economic power relations and engaging in social action that transcends the setting of the classroom and school. Counterhegemonic schools are thus generally characterized by an aspiration to be meaningful beyond the school community and a commitment to social transformation. Purpose/Focus of Study The study examines a unique bilingual, multicultural school in Israel/Palestine in its struggle to be broadly meaningful and sustainable by opening up enrollment beyond its binational (Jewish-Palestinian) community. In particular, the study analyzes the impact of incorporating external students on the school's counterhegemonic curricula, pedagogy, and dynamics, as well as the implications for the transformative potential of bottom-up democratic education initiatives in the absence of accompanying policy change more generally. Research Design The findings draw on data collected in a broader qualitative case study on multicultural, bilingual schools educating for democracy and social justice in different national, political, and cultural contexts. Data were collected and analyzed from semistructured open-ended individual interviews with school staff, parents, and founders; field observations; and document analysis. Findings The primary finding of this research is the paradox of being impacted while making an impact: The school's attempt to infiltrate the hegemony and expand and sustain its social impact led to the infiltration of external goals, interests, and power relations into its counterhegemonic agenda, curricula and pedagogy, and governance. This in turn undermined transformativity and transcultural border-crossing potential at the school and triggered a neoliberal process of commodification. Yet it also emerged that students still succeed in crossing national and religious identity-borders and in overcoming hegemonic perspectives of their essentialized identities. Conclusions Many obstacles stand between a counterhegemonic school and being socially meaningful, including sociohistorical and political factors. No less important, however, are the broader structural aspects to creating a space in which transformative schools can succeed. Although bottom-up attempts may push hegemonic forms to incorporate certain aspects of their vision, they cannot have meaningful and widespread impact if unaccompanied by broad support and action at the policy level and if they do not become organic parts of a larger transformative agenda.
