Essays on the Performance, Subsidization and Internationalization of Social Enterprises
2020
Social enterprises are hybrid organizations that tackle societal challenges by using conventional business models. Being hybrid organizations means that social enterprises pursue dual objectives: social (developmental) and financial. By taking performance, subsidization and internationalization perspectives, this thesis contributes to understanding the hybridity of social enterprises and how this hybridity drives their general operations and key decisions such as foreign market selection and targeting strategy.
Organ Recovery Procedure in Donation After Controlled Circulatory Death with Normothermic Regional Perfusion: State of the Art
2020
The global shortage of organ donors will not be resolved solely by relying on donation after brain death. Expansion to use of donation after controlled circulatory death will be needed to address the shortfall of organs for transplantation. The processes of warm ischemia threaten the viability of organs obtained after controlled circulatory death, but these can be minimized by well-organized donation pathways and new techniques of in situ organ preservation, such as normothermic regional perfusion. The use of extracorporeal membrane oxygenation (ECMO) devices for normothermic regional perfusion in liver transplantation can help reduce rates of biliary complications, ischemic type biliary le…
Similar morphokinetic patterns in embryos derived from obese and normoweight infertile women: a time-lapse study.
2013
Study question Does female obesity affect the dynamic parameters of embryo quality assessed by time-lapse analysis? Summary answer Female obesity does not affect the dynamic embryo quality as determined by image acquisition and time-lapse analysis. What is known already Female obesity impairs natural and assisted reproduction but there is no agreement on the specific contribution of gametes, embryos or endometrial receptivity. In this preliminary study the dynamic parameters of embryo quality are assessed for the first time by time-lapse analysis. Study design, size, duration Two-year cohort retrospective study comparing embryos from three groups of patients according to the presence of inf…
Time-dependent O2 consumption patterns determined optimal time ranges for selecting viable human embryos.
2012
Objective To evaluate correlations between metabolic activity and implantation potential of transferred embryos in a study based on oxygen (O 2 ) consumption (OC) measurements, because O 2 uptake is directly related to the capacity of an embryo to produce energy via adenosine triphosphate. Design Retrospective cohort study. Setting Infertility institute. Patient(s) Five hundred seventy-five injected oocytes in 56 first oocyte donation cycles with embryo transfer on day 3. Intervention(s) None. Main Outcome Measure(s) We analyzed embryo destination viability and implantation depending on the embryo OC rate obtained from 47,741 measurements (up to 85 measurements per embryo, 2–3 measurements …
Gestational surrogacy: Psychosocial aspects
2016
ABSTRACT Innovation in assisted reproductive technologies together with increased infertility and new family structures are increasing the use of gestational surrogacy as a means to have children. Before, during and after the process, it is necessary to study the psychosocial characteristics of triad members: the gestational surrogate, intended parents, and offspring. Research has indicated positive adaptation to the process and benefits for all members of the triad. Altruism is the main motivation of surrogates. Notably, psychological well-being has been found to be higher in individuals who have become parents through surrogacy than in those who have used egg donation or have followed a n…
Deficiencies in reporting results of lesbians and gays after donor intrauterine insemination and assisted reproductive technology treatments: a revie…
2015
At a time when increasing numbers of lesbians and gays consider parenthood using reproductive assistance in infertility centers, the present review aims to summarize the results obtained so far by lesbians after intrauterine insemination (IUI) and in-vitro fertilization (IVF) using donor spermatozoa (D-IUI and D-IVF, respectively) and gays entering into gestational-surrogacy programs. Data show that gays display normal semen parameters and lesbians exhibit no specific causes of female infertility except perhaps for polycystic ovary syndrome (PCOS) and some PCOS-related factors. Pair-bonded lesbians entering into D-IUI programs, tend to have higher pregnancy and delivery percentages followin…
Il lascito del proprio corpo a fini didattici e di ricerca. Il nobile (ma vano) intento della legge 10/2020
2021
The essay gives a sharp outline of the recent Italian law ruling body donation to science after death, as a personal choice exclusively founds on a conscious and free act of will. The statute, however, has not been met its aim, lacking of supporting the donor in making his consent fully effective. Indeed, as one of the highest displays of human solidarity, this issue would have required a balance between scientific research interests and individual autonomy protection.
Risk Communication in Assisted Reproduction in Latvia: From Private Experience to Ethical Issues
2013
The aim of this paper is to analyze the process of risk communication in the context of assisted reproduction in Latvia. The paper is based on a qualitative methodology and two types of data: media analysis and 30 semi-structured interviews (11 patients, 4 egg donors, 15 experts). The study explores a broad definition of risk communication and explores three types of risks: health, psychosocial, and moral. We ask (1), who is involved in risk communication, (2), how risks are discussed using different channels of communication, and (3), what ethical problems arise during this process. In the process of analysis, we identified four types of information channels and two strategies of risk comm…
Optimizing clinical exome design and parallel gene-testing for recessive genetic conditions in preconception carrier screening: Translational researc…
2019
Limited translational genomic research data have been reported on the application of exome sequencing and parallel gene testing for preconception carrier screening (PCS). Here, we present individual-level data from a large PCS program in which exome sequencing was routinely performed on either gamete donors (5,845) or infertile patients (8,280) undergoing in vitro fertilization (IVF) treatment without any known family history of inheritable genetic conditions. Individual-level data on pathogenic variants were used to define conditions for PCS based on criteria for severity, penetrance, inheritance pattern, and age of onset. Fetal risk was defined based on actual carrier frequency data accou…
A Large Scale Test of the Effect of Social Class on Prosocial Behavior
2015
Does being from a higher social class lead a person to engage in more or less prosocial behavior? Psychological research has recently provided support for a negative effect of social class on prosocial behavior. However, research outside the field of psychology has mainly found evidence for positive or u-shaped relations. In the present research, we therefore thoroughly examined the effect of social class on prosocial behavior. Moreover, we analyzed whether this effect was moderated by the kind of observed prosocial behavior, the observed country, and the measure of social class. Across eight studies with large and representative international samples, we predominantly found positive effect…
