Long-term exposure to ambient air pollutant concentrations is known to cause chronic lung inflammation, a condition that may promote increased severity of COVID-19 syndrome caused by the novel coronavirus (SARS-CoV-2). In this paper, we empirically investigate the ecologic association between long-term concentrations of area-level fine particulate matter (PM 2.5) and excess deaths in the first quarter of 2020 in municipalities of Northern Italy. The study accounts for potentially spatial confounding factors related to urbanization that may have influenced the spreading of SARS-CoV-2 and related COVID-19 mortality. Our epidemiological analysis uses geographical information (e.g., municipalities) and negative binomial regression to assess whether both ambient PM 2.5 concentration and excess mortality have a similar spatial distribution. Our analysis suggests a positive association of ambient PM 2.5 concentration on excess mortality in Northern Italy related to the COVID-19 epidemic. Our estimates suggest that a one-unit increase in PM 2.5 concentration (µg/m 3) is associated with a 9% (95% confidence interval: 6-12%) increase in COVID-19 related mortality.

The impact of the European Union common agricultural policy direct payments on land prices has received substantial attention in recent years, leading to heterogeneous evidence of capitalisation for both coupled and decoupled payments. In this paper, we provide an extensive review of the empirical works addressing this issue econometrically and compare their results through a Bayesian meta-regression model, focussing on the impact of decoupling and its implementation schemes. We find that the introduction of decoupled payments increased the capitalisation rate, although the extent of this increment hinges on the implementation scheme adopted by the member state.

Purpose Environmentally-friendly certifications have increased over the past decade within food supply chains. Although a large body of literature has explored the drivers leading firms to adopt such certifications, it has not closely examined the strategic motivations associated with their adoption. This paper aims to investigate an environmentally-friendly certification, VIVA, examining its role as an alternative form of supply chain governance. The aim is to investigate the drivers affecting the adoption of VIVA and to assess managerial perceptions related to transaction-related characteristics and the firm’s internal resources and capabilities. Design/methodology/approach This study draws upon both an extended transaction cost economics perspective, which is based on transaction risks and the resource-based view, which examines a firm’s internal resources. A survey was conducted via a structured questionnaire sent to all of the wine producers in charge of the decision regarding whether to adopt VIVA certification. A Hierarchal Bayesian Model was applied to analyse questionnaire responses. Such a model allows us to specify the probabilistic relationship between questions and latent constructs and to carry over uncertainty across modelling levels. Findings The adoption of this environmentally-friendly certification is envisioned as a tool to curb internal risks, and thus to manage behavioural uncertainty within the supply chain. A high level of exposure to exogenous transaction risks discourages firms from adopting VIVA certification. The certification system is not perceived as a promoter of operational capabilities. Managers are more likely to implement the certification when they expect that its adoption will leverage their potential knowledge of the supply chain or prompt new and better collaborations with the suppliers. Therefore, the certification can become a resource that interacts with the capabilities of the firm, expressing complementarities that stimulate the formation of dynamic capabilities. Research limitations/implications The identification of drivers from the two theoretical perspectives offers insights into the attributes that are perceived as important by managers and which, therefore, could be leveraged to foster the adoption of the environmental certification. The external validity of the study could be improved by extending the sample to other certifications and supply chains. Originality/value The study offers a different perspective on environmental certification. It demonstrates that considering the certification as an alternative form of supply chain governance opens up a set of efficiency and strategic considerations that could be addressed to promote the effectiveness of an environmental strategy within a supply chain

Objective:To investigate, through a questionnaire, older adults’ demographic and socio-economic characteristics, knowledge, attitudes and practices in terms of food safety and healthy diet; and to develop dietary and hygiene indices able to represent participants’ nutritional and food safety behaviour, exploring their association with demographic and socio-economic factors.Design:One-year cross-sectional study.Setting:Gemelli Teaching Hospital (Rome, Italy).Participants:People aged ≥65 years, Italian speaking, accessing the Centre of Ageing Medicine.Results:Mean age of the sample was 74 (sd 7·7) years. Subjective perception of a safe diet was high: 64·2 % of respondents believed they have a balanced diet. Interviewees got informed about proper nutrition mainly from television, magazines, newspapers, Internet (29·9 %) and from health professionals (34·8 %) such as dietitians, whereas 15·4 % from general practitioners. Regarding food safety, 33·8 % of participants reported to consume expired food, even more than once per month; between 80 and 90 % of participants reported to follow food safety practices during preparation and cooking, even though 49·3 % defrosted food at room temperature. Calculated dietary and hygiene indices showed that the elderly participants were far from having optimal nutritional and food safety behaviours.Conclusions:These results suggest it is necessary to increase the awareness of older adults in the matter of healthy diet and food safety. Specific and targeted educational interventions for the elderly and their caregivers could improve the adoption of recommended food safety practices and safe nutritional behaviours among older adults.

Meso‐institutions offer a promising theoretical approach for assessing the way in which firms govern their activities and transactions while embedded in the macro‐institutional environment. The concept of meso‐institutions also offers theoretical support when evaluating a wide variety of voluntary standards that have been introduced within value chains in recent decades. Such tools can be considered meso‐institutions because of their features, and because of their role in translating general normative rules into specific mechanisms that delineate the domain of activities of supply chain agents. While various aspects of meso‐institutions have been investigated, little is known about their relationship with micro‐level structures and the determinants of firm's voluntary participation. The present paper investigates the association between a private standard, different forms of transaction governance in the supply chain, and the role that internal and external risks play in voluntary participation in the standard. The analysis draws upon secondary data taken from a representative sample of firms that form part of the European soybean supply chain. Our findings show that firms that participate in this standard have fewer hybrid forms and higher levels of spot markets. This suggests that some of the functions of hybrid forms are fulfilled by the meso‐institution. The results also show that risks associated with firm's behavioral uncertainty are more conducive to the participation in the standard than environmental‐related risks.
