This is a study of Spanish immigration policies, the changes they have gone through over the past years, and more importantly, why. Three theoretical approaches are central to this thesis, namely: economic calculations, to do the right thing, and politics of insecurity. Through these approaches, different events and considerations that affect policy-shaping are highlighted and analysed. This

When China opened it borders in 1979, the country suffered from a severe brain drain as its most talented students left the country to take advantage of educational opportunities abroad. However these emigrant engineers, known locally as "sea turtles" or Chinese returnees, have become a valuable asset for Zhongguancun Science Park. The authorities for the high-tech park are now adopting

Background: The COVID-19 pandemic accelerated the use of telemedicine, specifically video consultations as they provide healthcare access in challenging situations where face-to-face encounters are not possible. Nevertheless, it remains largely unknown to what extent the organisation of general practice and national digital infrastructures have impacted the uptake and use of video consultations. O

The l’Hort de la Boquera site is located in the northeastern part of Iberia and its stone tool assemblage includes up to 25,000 flint artefacts. This is the first approach to the analysis of the raw material through an archaeopetrological study. Results were obtained by use of mineralogical techniques: macroscopic and petrographic analysis, Scanning Electronic Microscopy (SEM), Micro-Raman and X-R

Background: Exertional breathlessness is a cardinal symptom of people with chronic airflow limitation (CAL) and can be evaluated using cardiopulmonary exercise testing (CPET). Research Question: Does abnormally high exertional breathlessness in relationship to the rate of oxygen uptake (V′O2) and minute ventilation (V′E) indicate different underlying pathophysiologic mechanisms and clinical charac

While pregnancy clearly reduces the risk for Alcohol Use Disorder (AUD) onset, we know less about the impact on AUD risk of having young children and how these effects vary across maternal age and level of maternal AUD genetic risk. Therefore, in 1.2 million parous Swedish women born 1960-1995, we examined those with a first registration for AUD between ages 15-40 while first pregnant, or while ra

There is a positive association between bacteraemia with Streptococcus bovis-Streptococcus equinus complex (SBSEC) and colorectal cancer (CRC). However, the relationship between the timing of SBSEC bacteraemia and CRC is not well-established. Associations with other gastrointestinal cancers have also been suggested. Using national registries, we retrospectively examined the incidence of CRC and ot

Strontium isotope ratios in human teeth from the three Swedish prehistoric Stone Age hunter-fisher-gathering societies Norje Sunnansund (Maglemose), Skateholm (Ertebølle) and Västerbjers (Pitted Ware Culture) were analysed with laser ablation to produce data on both individual movement patterns and societal mobility trends. The analyses of teeth from both Skateholm and Västerbjers displayed homoge

The ancient Ventspils Lagoon is an area where human settlements have been located on former coastal landforms and sediments. However, the chronology of its development has so far not been studied in detail. Since the ancient lagoon is dominated by sand deposition, optically stimulated luminescence dating (OSL) was used to determine when the ancient coast was formed. Twenty-one OSL samples gave a w

OBJECTIVE: To investigate the mode of delivery and birth outcomes in relation to the duration of the passive second stage of labour in nulliparous women. METHODS AND FINDINGS: A retrospective cohort study of all nulliparous women (n = 1131) at two delivery units in Sweden. Maternal and obstetric data were obtained from electronic medical records during 2019. The passive second stage was defined as

Objective: Men who have sex with men (MSM) in sub-Saharan Africa remain hidden and hard to reach for involvement in HIV and sexually transmitted infection (STI) services. The aim of the current study was to describe MSM social networks in a large and a small Tanzanian city in order to explore their utility for peer-based healthcare interventions. Methods: Data were collected through respondent-dri

Objectives: The paper describes recruitment results and characteristics of the UP-TECH clinical trial sample, including level of care services use, informal caregiver burden and its determinants.Methods: UP-TECH is designed to test innovative care solutions for community-dwelling patients with moderate stage Alzheimer's disease and their caregivers in Italy. Four hundred and fifty patient-caregive

Rate-ratio asymptotic (RRA) analysis is carried out to elucidate the influence of carbon monoxide on the structure and critical conditions of extinction of nonpremixed methane flames. Steady, axisymmetric, laminar flow of two counterflowing streams toward a stagnation plane is considered. One stream, called the fuel stream is made up of a mixture of methane (CH4) and nitrogen (N2). The other strea

The inclusion of family members in the acute care of older persons with complex needs results in better coordination of care and reduces the frequency and/or duration of rehospitalisation. Therefore, healthcare professionals need a tool to assess the collaboration with family members on acute hospital wards. The aims were to test the psychometric properties of the Swedish version of the Family Col

Background: Smoking cessation may be very difficult, even if smoking aggravates the prognosis of a disease, which has been shown to be the case for persons with rheumatoid arthritis (RA). In contrast, an association in patients with osteoarthritis (OA) is still disputed. The primary objective was to compare smokers diagnosed with RA and OA to controls, regarding smoking cessation rates after follo

Objective. To psychometrically evaluate the Swedish translations of the short forms of the Pelvic Floor Impact Questionnaire (PFIQ-7), Pelvic Floor Distress Inventory (PFDI-20) and Pelvic organ prolapse/Urinary incontinence Sexual questionnaire (PISQ-12). Design and setting. University hospital. Sample. Forty-four patients awaiting prolapse surgery. Methods. The dual panel translation method follo

The accumulation of studies delimiting species in Amazonia has not only shed light on the patterns of its outstanding species richness but also allowed a better understanding of the processes of diversification within this immense region. Nevertheless, vast knowledge gaps remain even for prominent anuran species complexes, such as the Rhinella margaritifera species group. This clade of toads compr

China's technological growth in recent years has been explosive. Nowadays, Beijing based much of its socio-economic growth on improved technological performance in many areas. What are the main reasons that have enabled China to become a real IT giant? What are the geo-strategic implications of such growth in technology? To what extent can Chinese technical engineering improvements influence the c

OBJECTIVES: Health utilities derived from answers to generic health-related quality of life (HRQoL) questionnaires such as the EuroQol 5-Dimensions (EQ-5D) are often used in cost-utility analyses (CUAs) of new and expensive treatments. Different preference sets (tariffs) used in the computation of utility values and quality-adjusted life-years (QALYs) from questionnaire responses (health states) y
