A Pragmatic Theory of Everyday Imposition of Words in an Anonymous Thirteenth-Century Commentary on De anima (MS Prague, Metropolitan Chapter, M. 80, ff. 54vA–55rB)
No full textThe aim of this paper is to offer an edition of three anonymous questions on De anima II.8, contained in MS Prague, Metropolitan Chapter, M. 80, ff. 54vA–55vB and dated 1250–1260. The text offers an original theory of the everyday imposition of words. To present it, I (i) analyze the contemporary question-commentaries on De anima II.8; (ii) I present the theory of everyday imposition by discussing the analogies with, and differences from, Bacon’s contemporary pragmatic theory; and (iii) I discuss the hypothesis of the attribution of the text to Roger Bacon
Normalized Schrödinger equations with mass-supercritical nonlinearity in exterior domains
No full textWe consider the problem m −∆u + λu = |u|p−p−2u, where u ∈ H10 (Ω) satisfies |u|2 = m > 0, λ ∈ R and Ω is a smooth exterior domain. We prove the existence of a positive solution with a constrained Morse index less or equal than N + 1 and λ ≥ 0. We treat both the cases m fixed and RN \ Ω small and Ω fixed and m large
Worldwide E-waste Management Models: Delving into Pros and Cons and the Way Forward
No full textThe definition of electronic waste, also known as waste
electrical and electronic equipment (WEEE), keeps evolving.
However, traditionally it is compartmentalized as monitors,
printers, tablets, computers, servers, and cell phones.
Nowadays, the term e-waste encompasses almost every
business and household electronic product or device that
uses some sort of power or battery supply. Eventually, when
this electrical and electronic equipment (EEE) reaches its
end-of-life (EOL) or its useful life it becomes electronic
waste or WEEE, which these days is known as e-waste
(Read 2021). Therefore, the most generic and simplistic way
to define e-waste would be the definition agreed upon by
StEP (Solving the E-waste Problem): E-waste is a term used
to cover items of all types of electrical and electronic equipment
(EEE) and its parts that have been discarded by the
owner as waste without the intention of reuse.
Interestingly enough, e-waste may account for 3% (at the
most) of household solid waste, but it is considered one of
the most unsafe types of waste to manage (Kumar et al.
2017). For instance, around 70% of cadmium and mercury
that are found in the landfills of the USA comes from
electronic waste streams (Tanskanen 2013). Annually,
approximately 50 million tons of global WEEE end up in
the environment (UN 2009), while the volume grows by
3–5% per year (Yu et al. 2010). Around 80% of e-waste is not
even documented. Meanwhile, the developing nations turn out to be among
the biggest contributors to the WEEE due to their prevalent
informal system. The deficiencies of their current laws and policies on the management of WEEE have let the informal
recycling sector develop (Borthakur and Govind 2017),
where the most valuable materials are extracted. In the
meantime, the rest of the hazardous elements are tossed
away into the environment, bringing harm to human health
and obviously the environment (Baldе et al. 2017). Thus,
these mentioned deficiencies in WEEE treatment ultimately
contribute to the expansion of informal e-waste sectors in the
countries of Asia, South America, Oceania, and many other
African and poor countries. Furthermore, even with the
presence of a formal electronic waste collection/recycling/
management system in place, the informal system could still
be operational and significant (Shevchenko et al. 2021)

Enhancing the strategic alignment between environmental drivers of sustainability and the performance management system in Italian manufacturing firms
No full textPurpose The purpose of this paper is to provide managers with suitable strategic KPIs in decision-making processes, which aim to integrate the environmental dimension of sustainability at a business level in manufacturing organisations. Design/methodology/approach In view of the research proposal addressed, semi-structured interviews were conducted, based on theoretical milestones of the performance management system (PMS), with 48 managers that work in Italian manufacturing firms and specialise in green practices. Findings The authors developed a novel environmentally performed framework to adequately integrate environmental value drivers at a strategic level. Practical implications The resulting issues addressed in this paper, and their integration in the business strategy for managing environmental complexity, allows contributing, firstly, to the existing literature by suggesting the relevant key value drivers that need to be mostly studied from an accounting point of view. In addition, from these results, though their experience managers will have up-to-date key measures that could, in the future, help the integration process between the environmental aspect of the sustainability dimension and the PMS. Originality/value The results generate a robust roadmap for future analysis in this research field. Accordingly, the paper engenders a strategic alignment in the green transition process, providing scholars and practitioners with a clear view of the key sustainable drivers, metrics and potential solutions that have not been addressed to date
Evolution of behavioral research on E‐waste management: Conceptual frameworks and future research directions
No full textThe rapid growth of e-waste or waste electrical and electronic equipment (WEEE) has
garnered significant attention from scholars, particularly in the behavioral domain. This
study aims to conduct a comprehensive bibliometric analysis and content analysis to
provide a systematic review of WEEE-behavioral research. Firstly, a bibliometric analysis
was performed using Biblioshiny (R packages) on a sample of 293 articles from Scopus
and WOS databases. This part addresses the research question: A) How has the
WEEE-behavioral domain evolved over time in terms of key journals, institutions,
countries, trending topics, and research streams? Secondly, a content analysis was conducted
on 41 relevant articles that were able to address the following research questions:
B) What are the main theories utilized and their implications in WEEE-behavioral
research? and C) what are the potential directions for future research? The findings
reveal two distinct research categories, namely circular economic behavior and behavioral
spillovers, with seven underlying and emerging clusters followed by corresponding
research streams. Additionally, the theory of planned behavior (TPB) emerged as
the core theory that was extensively utilized and expanded upon. Consequently, this
study contributes to 1) understanding the evolution of the WEEE-behavioral domain,
2) proposing an integrated theoretical framework, 3) identifying the primary research
streams and their interconnections, and 4) suggesting avenues for future research, supported
by a robust conceptual model for hypothesis generation
Assessment of ecological quality status along the Apulian coasts (Eastern Mediterranean Sea) based on meiobenthic and nematode assemblages.
No full textCoastal environments may be impacted by several anthropogenic activities such as sewage discharges, fish-farming and hydrocarbons along with seaside tourism activities, all proved to have an effect on benthic and, particularly, meiobenthic communities. An ecological survey was conducted along Apulian coast (South Italy) to explore potential relationships between the degree of human disturbance and meiobenthic communities that is still unexplored. Sediment samples were collected in triplicate from 3 stations along each of 16 transects and at a different depth gradient. The levels of taxa richness and biodiversity of the meiobenthic and nematode assemblages were overall high. Meiobenthos was found to decrease in abundance and diversity along the depth gradient (from ~ 10 to 50 m) in relation to the increase of the mud fraction. Water Framework Directive and Marine Strategy Framework Directive suggest the creation of specific thresholds to define the EcoQ (Ecological Quality) status of the marine coastal systems. The thresholds applied on meiobenthos showed the worst conditions at the Brindisi harbour and at the mussel farm infrastructure of Castro. An overall moderate impact was detected also at the multiple-use Marine Protect Area of Porto Cesareo, likely due to the overwhelming number of tourist leading to an increase of organic enrichment (sewage discharge) negatively affecting the benthic communities. The main representatives of the nematode assemblages were taxa known as typical of muddy sediments. When EcoQ was assessed with the nematode thresholds, the worst EcoQ was found at T3 (Brindisi Harbour), T9 (Torre Specchia), and T10 (Alimini Lakes). The ecological conditions revealed by meiobenthic and nematode assemblages were generally consistent and seem to highlight a greater alteration of the meiobenthic communities along the Adriatic than the Ionian coasts
Housing spaces in nine european countries. A comparison of dimensional requirements
No full textModern housing units must meet new needs and requirements; housing dimensions and functional characteristics are relevant issues, mainly considering population ageing and disability. The housing standards of nine European countries were compared to analyze their ability to satisfy new population need, in terms of size. The regulations were downloaded from the websites of the official channels of each country. A wide variability in room size was observed (e.g., single room: from 9 m2 in Italy to 7 m2 in France, to the absence of any limit in England and Wales, GermanyHesse, and Denmark). Italian and French legislations define housing dimension considering the room destination and the number of people. The Swedish regulation provides performance requirements and functional indications but does not specify the minimum dimensions of habitable rooms. The rooms’ minimum heights vary between 2.70 m in Italy and Portugal and 2.60 m in the Netherlands, but no limits are established in England and Wales. A diverse approach among European countries regulations is observed: from a market-oriented logic one (e.g., England and Wales) in which room minimum dimensions are not defined to a prescriptive one (Italy) and one that is functionality-oriented (the Netherlands). However, considering the health, social, environmental, and economic trends, many of these standards should be revised
