This purpose of this paper is to describe a fast and easy method of both clustering samples and identifying active genes in cDNA microarray data.

The method relies on alternation of identification of the active genes using a mixture model and clustering of the samples based on Ward hierarchical clustering. The initial‐point of the procedure is obtained by means of a χ² test. The method attempts to locally minimize the sum of the within cluster sample variances under a suitable Gaussian assumption on the distribution of data.

This paper illustrates the proposed methodology and its success by means of results from both simulated and real cDNA microarray data. The comparison of the results with those from a related known method demonstrates the superiority of the proposed approach.

Only empirical evidence of algorithm convergence is provided. Theoretical proof of algorithm convergence is an open issue.

The proposed methodology can be applied to perform cDNA microarray data analysis.

This paper provides a contribution to the development of successful statistical methods for cDNA microarray data analysis.

The purpose of this paper is to analyze farmer behavior, considering their attitude toward food waste with particular focus on their involvement in the last phase of the process, the retail phase. It assesses the different approaches applied to food waste management and its future.

A sample of 35 farmers in the Porta Palazzo market, the biggest food market in the Turin Area (north-west Italy), was identified and a survey was carried out to determine the behavior and perception of farmers regarding food waste and the management of unsold food.

Results show that there is a high level of interest on the ethical and charitable aspects of food waste and unsold food. However, awareness and knowledge of the initiatives organized by institutions are not sufficient.

If policy makers and institutions have an understanding of farmer behavior, they can implement ad hoc initiatives to reduce food waste and build on the work already done by farmers. Additionally, farmers can help customers to better understand the products.

This study analyzes the perception of the food waste phenomenon for one type of traditional operator in the food supply chain, the farmer. The originality of the paper lies in the fact that it has not only considered the perception of food waste but also the management of unsold food in a market area.

This essay aims at retracing the intellectual and biographical events of the economist Gino Arias (1879–1940), examining more in detail the two seasons at the opposite ends of his life: the early one that saw him considerably committed to the Zionist cause and the one that, thirty years later, would force him to confront the racial laws of the Fascist regime.

Despite the seeming tragic continuity of these two phases, Arias’s case is a real historiographical paradox since, over the long span between the opposite ends of his biography, not only did he distance himself from the Zionist movement, but he also gradually laid the foundations for his upcoming and immediate dedication to Fascism; indeed, within the Fascist regime he would stand out as an authoritative and influential theorist of corporatism, the institutional solution Mussolini tried to exploit to organize the national economic life.

After carefully examining Arias’s early contributions to the Zionist cause (that include the establishment of the Florentine Zionist Group and that led him toward strongly nationalistic stances), this essay sums up Arias’s intellectual biography during the next years and then, thanks to unprecedented documents from the Italian Ministry of Interior, closely looks into his fate after his conversion to Catholicism in 1932 and up against the racial laws of 1938, as well as into his attempts to escape persecution. A few final observations will then try to highlight the dramatic exemplarity of his case.

The accommodation sector has a strong impact on the host destination in terms of waste production, use of natural resources, physical impact on landscape and natural environment, greenhouse gas emissions, etc. (Hall et al., 2016). For this reason, the increasing attention to sustainability, also in the tourism sector, requires us to rethink the planning of the tourist accommodation development with reference to this approach. Moreover, it is necessary to take into consideration some important emerging trends in tourist consumption, in particular the greater interest in experiential holidays, the deep impact of sharing economy and the phenomena of ‘home stay tourism’ and ‘living like a local’. All of these are significantly orientating the demand and the offer towards a greater attention to authenticity (Grayson & Martinec, 2004; Paulauskaite, Powell, Coca-Stefaniak, &, Morrison, 2017; Tussyadiah & Pesonen, 2016a and 2016b; Tussyadiah & Pesonen, 2018).

The sustainability, environmental, socio-cultural and economic dimensions must be respected to develop forms of sustainable accommodations (Boley & Uysal, 2013; Elkington, 1997, 1998, 2004; Farrell, 1992). They have to be respectful of local communities and their identity and culture, not going beyond the host environmental and social carrying capacities (Graefe & Vaske, 1987; Hernandez-Maskivker, Ferrari, & Cruyt, 2019; Van Der Borg, 1992; Van der Borg, Costa, & Gotti, 1996; Vargas-Sánchez, Porras-Bueno, & de los Ángeles Plaza-Mejía, 2011). Those aspects must be referred not only to environmental ecosystems (Buckley, 2000; Sánchez-Cañizares, Castillo-Canalejo, & Cabeza-Ramírez, 2018) but also to the art, cultural heritage and local socio-cultural tissue of the destination (García-Hernández, la Calle-Vaquero, & Yubero, 2017). This is especially true in tourist destinations that are characterized by a remarkable fragility and sensitiveness. As explained by Jeong, Zielinski, Chang, and Kim (2018, p. 2), sensitive tourist destinations are areas that support responsible tourism, but do not necessarily have all the characteristics of ‘ecotourism’ or ‘responsible tourism’ destinations, as provided in their common definitions (Dolnicar & Leisch, 2008). Responsible tourism is a kind of tourist behaviour that occurs when tourists understand the impact of their behaviour on the environment and local people, and abide by the socio-cultural and environmental norms of the site (Jeong et al., 2018, p. 1).

Our research is focused on Matera. This southern Italian town, which has been the European Capital of Culture in 2019 and World Heritage Site since 1993, has an ancient and very peculiar history. It is a complex urban cave situated in a deep natural canyon, continuously inhabited since the Palaeolithic period. Today Matera, which has frequently been the location of important movies, is a successful international tourist destination and has shown an uninterrupted increase in tourism over the last 20 years. Unfortunately, this rapid tourist growth is threatening the town centre and its surroundings that are part of a protected area. In fact, the dimensions of visitors' flows are endangering a delicate destination with a fragile equilibrium, together with its priceless cultural heritage, traditions and way of living. In addition, it is giving rise to a residents' negative attitude towards tourists. For all these reasons, investments should be made to favour the development of different types of tourist accommodations (e.g. diffuse hotels or some forms of sharing accommodations) that are respectful of local economy, physical environment and cultural heritage as well as of the host community and its culture, traditions and identity (Gilli & Ferrari, 2016).

In this analysis a qualitative approach was adopted by carrying on face-to-face interviews with stakeholders. The main aims were to study to what extent tourist accommodations are perceived as sustainable by the main stakeholders' categories in Matera today, how their sustainability could be improved and if town innovations in this field already exist or could be promoted.
