The Impact of At-Home Administration of Antineoplastic Treatments on Portuguese Patients
Background: In 2023, we introduced home-based anti-neoplastic treatments with the main goals of minimizing hospital visits and improving the quality of life for patients and their caregivers. Currently, we are assessing the impact of this care model on patients’ quality of life by administering questionnaires both prior to inclusion in the project and following treatment initiation. Approach: The quality of life of patients included in the projec…
High-low level features of destination personality
Research on destination branding has shown that tourists perceive destinations as having a personality structured around three dimensions (exciting, genuine, convivial). We offer a list of destination features likely to constitute the basis of the inferences individuals consensually make about those dimensions. We validated these associations in four empirical stages. Stage 1 assessed the tourist destination features that participants associate w…
Visualization of the research landscape on the 20 m shuttle run test in the last 15 years
Introduction Various studies have applied the 20-meter shuttle run test (20mSRT) to estimate cardiorespiratory fitness in different population groups, with the aim of associating test performance with the physiological, psychosocial, and cognitive health of children and young people. However, to date, no bibliometric review that analyzes the research landscape has been conducted. The objective was to conduct a bibliometric review to develop an ov…

A school-based intervention for a better future
There is evidence to support interventions in school settings as strategies for obesity prevention. Up-to-date homogeneous and community-based interventions for preventing childhood obesity are lacking, therefore Sintra Grows Healthy intends to fill this gap. Furthermore, Sintra Grows Healthy aims to contribute with relevant scientific findings that will allow the development of better strategies for policymakers and society to manage this major …
Rushing to the end
More and more social science studies are now acquiring data through the internet, reaching participantsonline. Some participants start out engaged and motivated to participate, but progressively slide into“rushing behaviors”. We inquired experts in survey responding about when, in online studies, theywould feel a desire for rushing (defined as speeding with no concerns about the quality of responses).This qualitative approach uncovered Repetition…

Social inclusion and exclusion of people with mental illness in Timor-Leste
These findings highlight the need to combat social exclusion of people with mental illness and their families by harnessing local Timorese sociocultural strengths. Such an approach could centre around people with mental illness and their families to: increase population mental health awareness; bolster rights-based and culturally-grounded mental health services; and promote inclusive and accessible services and systems across sectors
Sociolinguística e ensino de línguas
Este artigo pretende refletir acerca de alguns conceitos muito produtivos em Didática e Ensino de Línguas, favorecendo-se, para o efeito, o enquadramento teórico e metodológico da Sociolinguística. O estudo sobre o ensino de línguas, partilhando a visão de vários autores como Garmadi (1983), Elia (1987), Amor (1993), entre outros, deve ser realizado observando os pressupostos fornecidos pela Sociolinguística, bem como o valor que ela assume para …
Internet and Online Governmental Services Use Divide
Based on a sample of 21,546 individuals and 5,224 households, we use multilevel probit models to analyze the divides in the use of the Internet and online governmental services in Oman. We also study the main self-reported reasons for not using the Internet. The results reveal that characteristics such as education, employment status, nationality, role in the household, or age influence the likelihood of using both the Internet and online governm…
Are people-centred mental health services acceptable and feasible in Timor-Leste? A qualitative study
People-centred mental healthcare is an influential concept for health system strengthening and sustainable development that has been developed and promoted primarily in Western contexts. It characterizes service users, families and communities as active participants in health system development. However, we have limited understanding of how well people-centred mental healthcare aligns with the multiplicity of peoples, cultures, languages and cont…

Ten best resources for conducting financing and benefit incidence analysis in resource-poor settings
Many low- and middle-income countries are seeking to reform their health financing systems to move towards universal coverage. This typically means that financing is based on people’s ability to pay while, for service use, benefits are based on the need for health care. Financing incidence analysis (FIA) and benefit incidence analysis (BIA) are two popular tools used to assess equity in health systems financing and service use. FIA studies examin…
