The role of transformational entrepreneurship in managing a digital platform: the case of Yamamay

Purpose: Transformational entrepreneurship (TE) is a concept referring to the ability of entrepreneurs to face global challenges, such as the economic crisis, to improve the well-being of the community. Considering the current scenario of COVID-19, the way digital platforms support TE in overcoming a crisis, specifically the economic crisis caused by the pandemic, was analysed. Design/methodology/approach: To achieve the goal, the authors used the case study methodology. The interview was compared for the company analysed stands out due to its use of digital platforms as a tool to increase brand value. The authors conducted a semi-structured, open-ended interview with the entrepreneur and founder of Yamamay, a company operating in the retail sector. The results obtained from validity using the open coding method. Findings: The main findings show that the implementation of digital platforms supported the entrepreneur in formulating strategic choices that allowed the company to continue offering its services despite the store closures imposed by the pandemic. The whole concept of traditional retail has been and continues to be revised, rationalising it and integrating it with a more omnichannel logic in which digital platforms play a fundamental role. Practical implications: This paper provides market participants with useful information regarding the ability of this form of technology to support entrepreneurs in a crisis context. The results could also serve as an example for other retail companies regarding how to manage the consequences of the pandemic. Originality/value: This contribution represents an extension of the existing literature that deepens the understanding of the relationship between digital platforms and TE in a particular scenario, such as the COVID-19 pandemic. The effect of business decisions on the adoption of digital platforms to meet increasing and changing customer needs has been examined

CSR Reporting Practices: The Case of University of Bari

Corporate social responsibility (CSR) is a relevant topic for researchers and practitioners, widely explored with reference to companies. However, there are still few studies that address how higher education institutions integrate CSR practices into their strategy. This represents an important limitation since the university, through academic training and research activity, is the main promoter of CSR practices among different categories of stakeholders. Given the many benefits associated with the adoption of CSR, this study aims to explore the topic of CSR in universities, as they are institutions that act in the public interest and represent the ideal context for spreading the culture of preserving environmental and social, as well as economic, sustainability. The main purpose of this study is to explore, through the methodology of case studies, the type and effectiveness of the tools used by universities, specifically the University of Bari, to disseminate and integrate CSR into corporate strategy. Furthermore, this study aims to investigate how the university ensures the involvement of stakeholders, represented in particular by professors, administrators and students (stakeholder approach), in CSR initiatives. The analysis revealed the centrality of the investigated university in promoting CSR issues and sustainable territorial development. Finally, the study provides empirical evidence of the actions and methods of integrating CSR practices into corporate strategy and the ways in which stakeholders are involved

Middle Palaeolithic technical behaviour: Material import-export and Levallois production at the SU 13 of Oscurusciuto rock shelter, Southern Italy

The Oscurusciuto rock shelter, located in southern Italy (Puglia), has yielded a long Middle Palaeolithic stratigraphy rich in lithic assemblages, fireplaces and faunal remains, attesting Neanderthal occupation during the MIS 3. This paper is focused on the stratigraphic unit 13, consisting of a sandy compact deposit mixed with pyroclastic sediment above a thick level of tephra-US 14, identified as Mt. Epomeo green tuff (dated Ar/Ar ~ 55 ka).Level 13 represents the first stable human occupation after the deposition of tephra. Our goal was to examine the lithic assemblage of this stratigraphic unit by means of an interdisciplinary approach (technology, RMU, refitting program) in order to identify the economic behaviour and technical strategies of Neanderthals occupying the stratigraphic unit 13 of Oscurusciuto.The technical strategies applied indicate fragmentation of the reduction processes, as well as probable events of importation and exportation of objects. The lithic material were introduced at different stages of manufacturing. Pieces were introduced in the form of rough objects (pebbles), as well as semi-finished items, and as finished tools. This fragmentation of the chaîne opératoire also demonstrate the palimpsest nature of the level which is made up of different events happening one after another.The main concept of debitage was Levallois, generally realized on local jasper and siliceous limestone pebbles or cortical flakes. Jasper and siliceous limestone flakes, backed flakes and convergent flakes were the technological objectives of the debitage. A marginal volumetric debitage aimed at producing bladelets was also attested

Grotta del Cavallo (Apulia-Southern Italy). The Uluzzian in the mirror

The Uluzzian techno-complex is commonly considered to be a \u201ctransitional industry\u201d mostly on the basis of some inferred characteristics such as a chiefly flake-based production, a small amount of Upper Palaeolithic-like tools and a combination of Middle and Upper Palaeolithic elements both in the toolkit and in the technical systems. Following its discovery, the Uluzzian was identified as the Italian counterpart of the French Ch\ue2telperronian and attributed to Neandertals. However, a study issued in 2011 has established the modern character of the two deciduous teeth found in 1964 in the Uluzzian deposit of Grotta del Cavallo, fostering renewed interests to the Uluzzian culture, which real nature is almost unknown to the international scientific community. Here we provide preliminary results of the study on the lithic assemblage from the earliest Uluzzian layer and on backed pieces from the whole Uluzzian sequence of Grotta del Cavallo (Apulia, Italy), the type site of the Uluzzian. Moreover, besides a thorough review on the stratigraphy of Grotta del Cavallo (Supplementary Materials), we provide updated information on the human remains by presenting two unpublished teeth from the reworked deposit of the same cave. We conclude that the early Uluzzians demonstrate original technological behavior and innovations devoid of any features deriving or directly linked with the late Mousterian of Southern Italy. Therefore, the novelty nature of the Uluzzian techno-complex (with respect to the preceding Mousterian) complies with the recent reassessment of the two deciduous teeth from Grotta del Cavallo in suggesting an earliest migration of modern humans in southern Europe around 45,000 years ago

Worldwide prevalence, genotype distribution and management of hepatitis C

epatitis C virus (HCV) is one of the leading causes of chronic liver disease, cirrhosis, and hepatocellular carcinoma, resulting in major global public health concerns. The HCV infection is unevenly distributed worldwide, with variations in prevalence across and within countries. The studies on molecular epidemiology conducted in several countries provide an essential supplement for a comprehensive knowledge of HCV epidemiology, genotypes, and subtypes, along with providing information on the impact of current and earlier migratory flows. HCV is phylogenetically classified into 8 major genotypes and 57 subtypes. HCV genotype and subtype distribution differ according to geographic origin and transmission risk category. Unless people with HCV infection are detected and treated appropriately, the number of deaths due to the disease will continue to increase. In 2015, 1.75 million new viral infections were mostly due to unsafe healthcare procedures and drug use injections. In the same year, access to direct-acting antivirals was challenging and varied in developing and developed countries, affecting HCV cure rates based on their availability. The World Health Assembly, in 2016, approved a global strategy to achieve the elimination of the HCV public health threat by 2030 (by reducing new infections by 90% and deaths by 65%). Globally, countries are implementing policies and measures to eliminate HCV risk based on their distribution of genotypes and prevalence

Stylized facts of intraday precious metals

This paper examines the stylized facts, correlation and interaction between volatility and returns at the 5-minute frequency for gold, silver, platinum and palladium from May 2000 to April 2015. We study the full sample period, as well as three subsamples to determine how high-frequency data of precious metals have developed over time. We find that over the full sample, the number of trades has increased substantially over time for each precious metal, while the bid-ask spread has narrowed over time, indicating an increase in liquidity and price efficiency. We also find strong evidence of periodicity in returns, volatility, volume and bid- ask spread. Returns and volume both experience strong intraday periodicity linked to the opening and closing of major markets around the world while the bid-ask spread is at its low- est when European markets are open. We also show a bilateral Granger causality between returns and volatility of each precious metal, which holds for the vast majority subsamples
