Natural wine as an expression of sustainability: an exploratory analysis of Italy’s restaurant industry

Purpose – Although not yet fully defined, natural wine represents a sector that has gained the widespread attention of final consumers and, therefore, also of the restaurant world, because of its promise of sustainability. The objective of this paper is to understand Italian haute cuisine’s interest in natural wine, with the aim of analysing what qualifies this product as sustainable. Design/methodology/approach – After introducing a theoretical framework based on the concept of natural wine, a brief paragraph is dedicated to consumer preferences; subsequently, the analysis focusses on a questionnaire given to restaurateurs to determine the impact that natural wine has had in the Italian context. The results try to identify the importance that restaurateurs give to the characteristics of natural wine and their propensity for using such wine in their own businesses. Findings – The analysis, conducted on a sample of medium-high range restaurants, highlights their strong interest in natural wine, as a result of the final consumers’ attitude towards wine with characteristics attributable to sustainability. The positive perception by restaurateurs is similar across Italy, both geographically and in terms of the size of the restaurant. Originality/value – The originality of the work is the focus on the world of restaurants. To date, the literature on natural wine remains embryonic and always refers to the final consumer. This research is the first step in a broader study that will involve a greater number of restaurants, extending beyond Italy to all of Europe, with the aim of understanding the real development potential of natural win

The role of individual social responsibility and corporate social responsibility in the tax fraud war: a comparison between the priorities of Italian and Romanian consumers

Corporate social responsibility (CSR) and fiscal responsibility have become a hot topic of debate in recent years. Many studies have investigated CSR and tax avoidance; however, such studies have overlooked countries' tax cultures and fiscal responsibility from a historical perspective and have not addressed how these elements affect current tax avoidance practices. Using a questionnaire, that was administered to a sample of Italian and Romanian respondents, and inferential techniques (Mann–Whitney-test and correlation-test) the paper tries to understand the aspects that be useful in the future development and implementation of more robust fiscal ISR and CSR processes. Our results reveal similarities and differences between the relevance of certain aspects between countries, identifying tax culture as a distinctive element from a geographical point of view. Despite the considerable differences, we found a strong demand for greater transparency of the company with administrations and communities and desire for the development of initiatives to spread a responsible tax culture

Uso de séries temporais no estudo do mercado de trigo.

Existem diversas metodologias com base em dados de séries temporais aplicáveis a estudos de modelos de previsão. Com o intuito de analisar a evolução do mercado de trigo foram utilizados dois desses modelos, Arima e Espaço de Estados, para previsão das séries: produção, consumo e importação de trigo do Brasil. As séries observadas compreendem o período 1972- 2008 e as previsões se estendem até 2018. Taxas de crescimento também foram calculadas para as séries analisadas. Os resultados obtidos mostram que as projeções da produção e da importação foram as que melhor se ajustaram aos dados. As estimativas indicam perspectivas de crescimento para a produção, o consumo e a importação de trigo. A maior taxa de crescimento foi encontrada para a produção. Conclui-se que o Brasil não conseguirá se tornar auto-suficiente na produção de trigo, mantendo sua dependência em relação aos mercados exportadores, uma vez que o consumo continuará aumentando

Social Reporting Impact on Non-Profit Stakeholder Satisfaction and Trust during the COVID-19 Pandemic in an Emerging Market

Attracting resources to achieve established goals makes social reporting necessary in relation to an organization's stakeholders, and reports on the social impact of resource use and activities have an essential role in increasing stakeholder satisfaction and trust. The COVID-19 pandemic emphasized the importance of sustainable development goals and transparent social reporting for different categories of stakeholders. This paper aims to identify the social reporting dimensions that influence the satisfaction and trust of the primary stakeholders of non-profit organizations in an emerging market (Romania), i.e., managers, employees, members, volunteers, donors, and collaborators. The results reveal the positive influence COVID-19 reporting had on stakeholder satisfaction. The lack of formal reporting has a weak yet statistically significant negative influence on stakeholder satisfaction, thus positively influencing the perceived need for external and internal auditing. Stakeholder trust in an organization is strongly and positively influenced by satisfaction with the organizational activity and internal auditing and is negatively influenced by a lack of formal reporting

Nature versus Nurture: The curved spine of the galaxy cluster X-ray luminosity -- temperature relation

The physical processes that define the spine of the galaxy cluster X-ray luminosity -- temperature (L-T) relation are investigated using a large hydrodynamical simulation of the Universe. This simulation models the same volume and phases as the Millennium Simulation and has a linear extent of 500 h^{-1} Mpc. We demonstrate that mergers typically boost a cluster along but also slightly below the L-T relation. Due to this boost we expect that all of the very brightest clusters will be near the peak of a merger. Objects from near the top of the L-T relation tend to have assembled much of their mass earlier than an average halo of similar final mass. Conversely, objects from the bottom of the relation are often experiencing an ongoing or recent merger.Comment: 8 pages, 7 figures, submitted to MNRA

Exposure during embryonic development to Roundup® Power 2.0 affects lateralization, level of activity and growth, but not defensive behaviour of marsh frog tadpoles

As glyphosate-based herbicides, sold under the commercial name Roundup®, represent the most used herbicides in the world, contamination of the freshwater environment by glyphosate has become a widespread issue. In Italy, glyphosate was detected in half of the surface waters monitoring sites and its concentrations were higher than environmental quality standards in 24.5% of them. It can last from days to months in water, leading to exposure for aquatic organisms and specifically to amphibians’ larvae that develop in shallow water bodies with proven effects to development and behaviour. In this study, we tested the effects of a 96 h exposure during embryonic development of marsh frog's tadpoles to three ecologically relevant Roundup® Power 2.0 concentrations. As expected, given the low concentrations tested, no mortality was observed. Morphological measurements highlighted a reduction in the total length in tadpoles exposed to 7.6 mg a.e./L, while an increase was observed at lower concentrations of 0.7 and 3.1 mg a.e./L compared to control group. Tadpoles raised in 7.6 mg a.e./L also showed a smaller tail membrane than those raised in the control solution. Regarding behaviour, we tested tadpoles in two different sessions (Gosner stages 25 and 28/29) for lateralization, antipredator response and basal activity. Lower intensity of lateralization was detected in tadpoles raised at the highest Roundup® concentration in the first session of observation, while no significant difference among treatments was observed in the second one. In both sessions, effects of Roundup® Power 2.0 embryonic exposure on antipredator response, measured as the proportional change in activity after the injection of tadpole-fed predator (Anax imperator) cue, were not detected. Tadpoles exposed during embryonic development to Roundup® exhibited lower basal activity than the control group, with the strongest reduction for the 7.6 mg a.e./L treatment. Our results reinforce the concern of Roundup® contamination impact on amphibians

Designing Successful Business Strategies for Public Private Partnerships. An ontological approach

Purpose The purpose of this paper is to present an innovative approach for the strategic design of Public Private Partnerships (PPP) and Private Finance Initiatives (PFI) based on ontology. Design/methodology/approach Adopting a historic approach, it introduces a posteriori knowledge, deriving from the scheme’s stakeholders at the construction and implementation phase of PPPs. Continuous failures of these collaboration schemes and initiatives underline the necessity for a novel project structure. The conceptual argument is based both on empirical and epistemological approach. It integrates the value added of the ontological theory in the PPP/PFI business strategy. Findings The research emphasises contemporary design gaps of their current structure and proposes an ontological redesign. The proposed redesign produces a conceptually innovative scheme, which enhances the value added business strategies and their objectives to the structure of these collaborating schemes. Practical implications The ontological design of this paper is useful for academics and business consultants around the world and especially in Europe for the successful growth and development of such dynamic collaborations. Originality/value Enterprise ontology bridges conceptual and structural gaps of strategic objectives, which are primarily responsible for the failures of PPP collaboration

Analyticity and criticality results for the eigenvalues of the biharmonic operator

We consider the eigenvalues of the biharmonic operator subject to several homogeneous boundary conditions (Dirichlet, Neumann, Navier, Steklov). We show that simple eigenvalues and elementary symmetric functions of multiple eigenvalues are real analytic, and provide Hadamard-type formulas for the corresponding shape derivatives. After recalling the known results in shape optimization, we prove that balls are always critical domains under volume constraint.Comment: To appear on the proceedings of the conference "Geometric Properties for Parabolic and Elliptic PDE's - 4th Italian-Japanese Workshop" held in Palinuro (Italy), May 25-29, 201

Microfluidic tools for enhanced characterization of therapeutic stem cells and prediction of their potential antimicrobial secretome

Antibiotic resistance is creating enormous attention on the development of new antibiotic-free therapy strategies for bacterial diseases. Mesenchymal stromal stem cells (MSCs) are the most promising candidates in current clinical trials and included in several cell-therapy protocols. Together with the well-known immunomodulatory and regenerative potential of the MSC secretome, these cells have shown direct and indirect anti-bacterial effects. However, the low reproducibility and standardization of MSCs from different sources are the current limitations prior to the purification of cell-free secreted antimicrobial peptides and exosomes. In order to improve MSC characterization, novel label-free functional tests, evaluating the biophysical properties of the cells, will be advan-tageous for their cell profiling, population sorting, and quality control. We discuss the potential of emerging microfluidic technologies providing new insights into density, shape, and size of live cells, starting from heterogeneous or 3D cultured samples. The prospective application of these technologies to studying MSC populations may contribute to developing new biopharmaceutical strategies with a view to naturally overcoming bacterial defense mechanisms
