Recovery of oil with unsaturated fatty acids and polyphenols from chaenomelessinensis (Thouin) Koehne: Process optimization of pilot-scale subcritica…
2017
The potential effects of three modern extraction technologies (cold-pressing, microwaves and subcritical fluids) on the recovery of oil from Chaenomelessinensis (Thouin) Koehne seeds have been evaluated and compared to those of conventional chemical extraction methods (Soxhlet extraction). This oil contains unsaturated fatty acids and polyphenols. Subcritical fluid extraction (SbFE) provided the highest yield—25.79 g oil/100 g dry seeds—of the three methods. Moreover, the fatty acid composition in the oil samples was analysed using gas chromatography–mass spectrometry. This analysis showed that the percentages of monounsaturated (46.61%), and polyunsaturated fatty acids (42.14%), after appl…
Identification and characterization of circadian clock genes in the pea aphid Acyrthosiphon pisum
2010
The molecular basis of circadian clocks is highly evolutionarily conserved and has been best characterized in Drosophila and mouse. Analysis of the Acyrthosiphon pisum genome revealed the presence of orthologs of the following genes constituting the core of the circadian clock in Drosophila: period (per), timeless (tim), Clock, cycle, vrille, and Pdp1. However, the presence in A. pisum of orthologs of a mammal-type in addition to a Drosophila-type cryptochrome places the putative aphid clockwork closer to the ancestral insect system than to the Drosophila one. Most notably, five of these putative aphid core clock genes are highly divergent and exhibit accelerated rates of change (especially…
Homeless Adults' Recovery Experiences in Housing First and Traditional Services Programs in Seven European Countries.
2020
Across Europe, as governments turn to housing-led strategies in attempts to reverse rising rates of homelessness, increasing numbers of Housing First (HF) programs are being implemented. As HF programs become more widespread, it is important to understand how service users experience them compared to the more prevalent traditional treatment-first approach to addressing long-term homelessness. Although there is a large body of research on service users' experiences of Housing First compared to treatment-first in North American contexts, comparatively less is known about how these two categories of homeless services are experienced in the European context. In a correlational and cross-section…
Network analysis of knowledge and practices regarding sexual and reproductive health: a study among adolescent street girls in Kinshasa (DRC)
2016
The aim of the study was to ascertain the influence of knowledge and interventions in sexual and reproductive health and contraception practices among adolescent street girls from Kinshasa, Democratic Republic of the Congo.A cross-sectional study was carried out among street girls between 12 and 21 years of age. A standardised questionnaire was used, encompassing socio-demographic data and knowledge and practices regarding sexual and reproductive health. A network analysis was carried out.The study comprised 293 street girls. The mean age was 17.1 years (range 12-21 years) and the mean time spent living on the streets was 3.9 years (range 0-15 years). Commercial sex was reported by 78.5% (9…
Europeans' willingness to pay for ending homelessness: A contingent valuation study.
2020
The purpose of this study is to assess the utility value European citizens put on an innovative social program aimed at reducing homelessness. The Housing First (HF) model involves access to regular, scattered, independent and integrated housing in the community with the support of a multidisciplinary team. Currently, HF is not implemented by most European countries or funded by healthcare or social plans, but randomised controlled trials have stressed significant results for improved housing stability, recovery and healthcare services use. The broader implementation of HF across Europe would benefit from a better understanding of citizens' preferences and "willingness to pay" (WTP) for med…
Working with People Experiencing Homelessness in Europe
2022
In Europe, the widespread transition from the Traditional Staircase (TS) model to the Housing First (HF) model is transforming the way social service providers work with people experiencing homelessness. This study examined social service providers’ perspectives in both models regarding factors that facilitate or hinder their work. Data were collected through 17 photovoice projects involving 81 social service providers from eight European countries. The results show factors affecting social service providers’ work at three levels: systemic, organizational, and individual. Professionals in TS and HF identified similar topics; however, TS providers discussed more obstacles to work. Implicatio…
#IoRestosenzaCasa. La condizione delle persone senza dimora durante la pandemia
2020
To reach the identification of the serious marginality, in a moment of pandemic, is not a very simple operation considering the amplification of inequalities throughout the national territory, but also internationally. The Covid-19 pandemic has severely tested the resilience of States and social and health care systems. It is inevitable that the most affected by the lockdown, which marked the country from March to May 2020, were the homeless. When we talk about homeless people, issues, questions, difficulties arise immediately. The first limit is to have the count of the phenomenon in numerical terms. Data on the presence of homeless people in Italy date back to 2014 and estimate 50,724 hom…
Home as a Base for a Well-Lived Life: Comparing the Capabilities of Homeless Service Users in Housing First and the Staircase of Transition in Europe
2020
Nussbaum’s Central Capabilities refer to the elements of a well-lived life, and many adults who experience homelessness are deprived of these capabilities. The study aim was to investigate whether service users experience different homeless services as affording or constraining capabilities. We conducted semi-structured interviews with homeless service users (n = 77) in Housing First (HF) and staircase services (SS) in eight European countries. We used thematic analysis to identify three themes: autonomy and dependency, the relational impact of living arrangements, and community interaction and stigma. While SS participants were able to address their bodily integrity and health, their highe…
Structure and agency in capabilities-enhancing homeless services: Housing first, housing quality and consumer choice
2021
The capabilities approach, a framework for understanding and measuring inequality, stipulates that equality is best understood as the freedom to do and be within a particular context. Homelessness has been referred to as a situation of ‘capabilities deprivation’, and the extent to which homeless services restore or enhance capabilities is of increasing interest. As part of a large, eight-country study of homelessness in Europe, we examined the extent to which adults with histories of perceived the services they receive as capabilities-enhancing. We collected data at two time points: baseline (nt1 = 565) and follow-up (nt2 = 399). Measures included perceived capabilities, choice and housing …
Comparison of housing first and traditional homeless service users in eight european countries: Protocol for a mixed methods, Multi-site study
2020
Background Homeless services expend considerable resources to provide for service users’ most basic needs, such as food and shelter, but their track record for ending homelessness is disappointing. An alternative model, Housing First, reversed the order of services so that homeless individuals are offered immediate access to independent housing, with wraparound supports but no treatment or abstinence requirements. Although the evidence base for Housing First’s effectiveness in ending homelessness is robust, less is known about its effectiveness in promoting recovery. Objective The objective of this research is to compare rehabilitation- and recovery-related outcomes of homeless services us…
