Acceptance of Online Health Services for Self-Help in the Context of Mental Health : Understanding Young Adults Experiences

2018

This paper explores the understanding of the acceptance of online health services from a selfhelp perspective in the context of mental health. By examining the experiences of young adults, this paper develops a framework to leverage the current understanding of the factors that would support the acceptance and use of these types of services. To this end, a multidisciplinary perspective incorporating knowledge from the service marketing, health, and information systems literature is used. The results suggest that the production of online services that are meant for self-help purposes necessitates a focus on the acceptance of technology and, more importantly, instrumental value creation, as t…

Chronic otitis caused by heterotopic brain tissue in pterygopalatine fossa

2007

Summary Heterotopic brain tissue is a rare is congenital anomaly, it may present at any age but it is frequently in infancy. This anomaly can occur most frequently in nasal region, although rests elsewhere in the digestive tract, in facial tissue or in lungs have been reported. Heterotopic brain tissue has been defined as a mass composed of mature brain tissue, outside the cranial cavity or spinal canal. We present a 9 years old girl with history of left chronic otitis and nasal obstruction caused by heterotopic brain tissue in pterygopalatine fossa.

Fresh-cut products from cactus species

2005

Various species of Cactaceae family can serve a source of delicious and healthy fresh foodstuffs. Marketing cacti as ready-to-eat (fresh-cut) products may significantly expand their consumption, on condition that their quality, safety and longevity would answer the market demands. The present work was aimed at studying the storability of fresh-cut products prepared from several edible cactus species and looking for ways to improve their keeping quality. The experiments included fruit of cactus pear Opuntia ficus-indica (L.) Miller, cactus apple (koubo) Cereus peruvianus (L.) Miller, and dragon fruit (pitaya) Hylocereus undatus (Haw.) Britton and Rose, as well as cladodes (pads) of nopal (ve…

Individual and shared digital repertoires : older adults managing digital services

2023

The rise of public and other non-recreational digital services is based on the idea of catering to the daily needs of the citizens cost-efficiently and with ease. Previous research has approached the use of digital services mainly from the perspective of an individual, while the significance of shared practices of use has attracted only a little attention. In this article, we (1) examine the incentives and limitations associated with the use of non-recreational digital services, which either encourage or discourage older adults to use them. Based on the first question, we then ask (2) how older adults in this study manage those non-recreational digital services they have chosen to use. Our …

Experiences, reputation, references and decision-making in an online hospitality network

2014

The aim of this thesis was to analyse behavioural patterns that occur after a negative experience during a hospitality exchange. The focus of this study is the largest online hospitality network to date, the CouchSurfing Project. CouchSurfing enables travellers to connect and to offer each other help in form of a free hospitality exchange. Furthermore, CouchSurfing presents a platform for cultural exchange and the possibility for members to connect in this online-offline community. As part of a qualitative study, a voluntary online questionnaire has been distributed and answered by 35 CouchSurfing members. The results give insight of how they deal with a negative experience after offline in…

Inverse opal TiO2 photocatalytsts for environmental applications

2017

This work aims to study the influence that different doping agents can have on the chemico-physical properties of TiO2 synthesized with the task to obtain an ordered porous material with an inverse opal structure and to evaluate the photocatalytic performance of these systems in the degradation of a model dye molecule (Rhodamine B, RhB) in water under Visible light irradiation.
