STRATEGIES FOR A MORE SUSTAINABLE HOME FOOD DELIVERY SYSTEM: THE CASE STUDY OF DELIVEROO
2020
The aim of this work is to investigate the main enabling factors facilitating the diffusion of the emobility in the food delivery sector through the analysis of the Deliveroo case study. Deliveroo s.r.l. has been chosen for two main reasons. First, the growing importance of the company in the food delivery market, with an annual turnover increase of +120 million euros in 2017, becoming one of the major national players for food delivery. Second, the company recently adopted a strategy to support the diffusion of electric mobility for home delivery through the subscription of specific agreements.
#How Can We Help You?: An Instagram-Based Online Self-Help for Eating Disorders
2023
In recent years, there has been a noticeable increase in online self-help treatments and peer-support programs for eating disorders. The possibility of easily accessing them anytime makes these programs an important support tool and an influencing source for increasing motivation to change. The aim of this work is to describe the #How can we help you? project, its initial feedback received from users, and its future directions. Researchers and clinicians developed an Instagram profile (Dicci Come Aiutarti) based on psychoeducation, aimed at orienting those suffering from a self-reported eating disorder towards clinical care, providing information about eating concerns and related constructs…
What matters more in open access journal publishing : Scientific rigor or financial vigor?
2021
Academics and librarians around the world are raising concern about the current state of scholarly journal publishing in that the majority of journals are under the control of five multinational commercial journal publishing companies. Some are advocating for scholars to take back control of scholarly communication, particularly because it is the academics who are supplying and managing most of the content for journals. Open access publishing is one option, but the question of sustainability in funding streams raises concerns. Also the roles of scholarly societies, academic association, and universities in looking for stability in nonprofit journal publishing are discussed.

A probabilistic long‐term framework for site‐specific erosion analysis of wind turbine blades: A case study of 31 Dutch sites
2021
Abstract Rain‐induced leading‐edge erosion (LEE) of wind turbine blades (WTBs) is associated with high repair and maintenance costs. The effects of LEE can be triggered in less than 1 to 2 years for some wind turbine sites, whereas it may take several years for others. In addition, the growth of erosion may also differ for different blades and turbines operating at the same site. Hence, LEE is a site‐ and turbine‐specific problem. In this paper, we propose a probabilistic long‐term framework for assessing site‐specific lifetime of a WTB coating system. Case studies are presented for 1.5 and 10 MW wind turbines, where geographic bubble charts for the leading‐edge lifetime and number of repai…
Maahanmuuttajataustaisten lasten varhaisten matemaattisten taitojen tukeminen Ekapeli-Matikka-tietokonepelillä
2014
Tämän tutkimuksen tarkoitus oli selvittää, tukeeko Ekapeli-Matikka-tietokonepeli maa-hanmuuttajataustaisten lasten heikkoja varhaisia matemaattisia taitoja. Tutkimusasetel-ma koostui kahdesta alkumittauksesta, kolmen viikon interventiojaksosta, loppumitta-uksesta ja viivästetystä loppumittauksesta. Mittauksissa käytettiin samoja arviointiteh-täviä. Arviointitehtävillä mitattiin lukumäärän laskemisen, lukusanojen luettelun ja lu-kumäärien erilaisten esitystapojen yhdistelemisen taitoja sekä yhteenlaskutaitoa. Tutki-mukseen osallistui 14 lasta, jotka olivat maahanmuuttajataustaisia, esikoulunopettajien-sa mielestä matematiikassa tuen tarpeessa olevia lapsia. Seitsemän lasta pelasi tutki-mukse…
Sustainability Perspectives in Organizational and Workplace Learning Studies
2022
The association between sustainability and learning in organizations and workplaces represents a current articulated grand challenge for human resource development (HRD) and learning studies and practice, which calls for integrated inquiries. However, studies of learning in organizations and workplaces deal with sustainability in scattered and diverse ways that promote calls for more integrated understandings of the different approaches and associations. This article outlines the results from a scoping thematic review mapping out leading perspectives within the research fields of HRD, organizational learning (OL) and workplace learning (WPL). This article thus explores the perspectives that…
Study of oral microbiota and diet as casual factors of Black Stains in the pediatric patient
2019
The aim of the following study is to identify and quantify microorganisms in the saliva of black stain patients using species-specific probes for Actinomyces israelii, Actinomyces naeslundii, Streptococcus mutans and Lactobacillus spp, as well as a universal probe for bacterial 16S rDNA, to obtain the figure of the total bacterial counts (for test and control group). This study represents a first phase of the research line on extrinsic tooth pigmentation on developmental age patients. Materials and methods. The selected sample is composed of 20 subjects aged between 2 and 15 years and in good general and oral health among the patients included in a dental examination trial at the Department…
Organic food consumption: The relevance of the health attribute
2020
During the last decades, organic food products have become the main sustainable alternative to conventional food consumption. Among the several organic food attributes that consumers recognize in organic food, healthiness has been reported as the primary motivation to buy products certified as organic. The objective of the current study is to assess the relative weight of the health attribute among other recognized organic food attributes. To achieve this aim, a multiple price list (MPL) methodology is adopted to elicit consumers&rsquo
Increasing Sustainability of Growing Media Constituents and Stand-Alone Substrates in Soilless Culture Systems
2020
Peat-free growing media constituents and stand-alone substrates are the basis for the economic and ecological efficiency of the soilless culture system. Nevertheless, divergence between the model and practice still exists, coming from large gaps in the knowledge of alternative organic materials and of their effects on crop performance. A more detailed understanding of these topics is necessary to increase the soilless culture management capacity. In this respect, this critical review collects research outcomes concerning the sustainability of soilless culture and growing media constituents and their impact on the environment. In particular, the review covers designated articles stressing th…
