[Fertility preservation in the oncology patient].

2017

In recent years, medical advances have substantially improved survival of cancer patients, generating growing concern about the quality of life of the survivors. Increased attention has been paid to reproductive problems after oncological treatments. International guidelines on fertility preservation in cancer patients require that healthcare teams discuss, as early as possible, the impact of cancer treatments on fertility and encourage access to fertility preservation techniques. The development of these techniques in women is a recent effort and many patients and health care providers are not familiar with their rapid expansion. This article discusses indications, results, and risks of th…

Health outcomes of children born after IVF/ICSI: a review of current expert opinion and literature

2014

The Sixth Evian Annual Reproduction (EVAR) Workshop Group Meeting was held to evaluate the impact of IVF/intracytoplasmic sperm injection on the health of assisted-conception children. Epidemiologists, reproductive endocrinologists, embryologists and geneticists presented data from published literature and ongoing research on the incidence of genetic and epigenetic abnormalities and congenital malformations in assisted-conception versus naturally conceived children to reach a consensus on the reasons for potential differences in outcomes between these two groups. IVF-conceived children have lower birthweights and higher peripheral fat, blood pressure and fasting glucose concentrations than …

Ovulation induction and epigenetic anomalies

2013

In this systematic review of ovulation induction and epigenetic control, studies mainly done in the mouse model highlight how hormone treatments may be prejudicial to the epigenetic reprogramming of gametes as well as early embryos. Moreover, the hormone protocols used in assisted reproduction may also modify the physiologic environment of the uterus, a potential link to endometrial epigenetic disturbances. At present, the few available data in humans are insufficient to allow us to independently determine the impact of a woman's age and infertility problems and treatment protocols and hormone doses on such processes as genomic imprinting.

Decoding the XXI Century’s Marketing Shift: An Agency Theory Framework

2016

Since the beginning of the XXI century, marketing theory has moved through a series of epistemological shifts from modern positivism to postmodern constructivism. This has resulted in a series of changes to the main concepts of “traditional” marketing such as: market, product, customer, and value. These shifts can be better viewed under a social cybernetics approach such as agency theory. This is because there is now a view that the linear concept of value creation needs to give way to the more complex process of value cocreation, where value is created collectively. Agency theory is one approach that is able to shed light on how customers and providers are able to recursively create collec…

Online Academic Networks as Knowledge Brokers: The Mediating Role of Organizational Support

2018

Placing online academic networks in the framework of social, cultural and institutional “deterritorialization,” the current paper aims at investigating the functionality of these new forms of transnational and trans-organizational aggregations as knowledge brokers. The emphasis is laid on the influence of human collective intelligence and consistent knowledge flows on research innovation, considering the role of organizational support within higher education systems. In this respect, the research relied on a questionnaire-based survey with 140 academics from European emerging countries, the data collected being processed via a partial least squares structural equation modelling technique. E…

Place brand as an emergent property: The case of Vascitour and Naples

2019

In this paper, by adopting a systemic framework, we argue that place's adaptive connotation be considered as a mere result of endogenous processes but as a viable system that will remain viable if it can continue to answer the needs of its numerous heterogeneous internal and external socio-economic agents. Place can be seen as a complex adaptive system characterized by a more or less planned evolution, driven by both top-down and bottom-up processes, and composed of various interconnecting parts that, at the same time, can be seen as wholes at different levels as an holoarchy. The model of the holoarchy allows to consider the place as the result of both planned and spontaneous relationships…

Systemic Approaches for Business Innovation and Sustainability. Editorial Note to the Special Section for the 2nd BS Lab Symposium-Rome 2014

2014

Our times are characterized by intense transformations in the competitive logics of markets and, broadly speaking, of business systems. Business scenarios today are typified by dynamism, connectivity, nonlinearity, and emergent properties—i n other words by ‘complexity’ (Dominici,2012). The systemic approach has been pivotal to open new lenses and understandings of the inner dynamics of complex systems. In recent times, we have witnessed a paradigm shift in the managerial approach from the whole/part model to the systemice nvironmental approach. This shift generated the epistemological frame of the systemic approach to social sciences in the fields of sociology, management and economics (Pita…

Using organizational influence processes to overcome IS implementation barriers: lessons from a longitudinal case study of SPI implementation

2014

A fundamental tenet of the information systems (IS) discipline holds that: (a) a lack of formal power and influence over the organization targeted for change, (b) weak support from top management, and (c) organizational memories of prior failures are barriers to implementation success. Our research, informed by organization influence, compellingly illustrates that such conditions do not necessarily doom a project to failure. In this paper, we present an analysis of how an IS implementation team designed and enacted a coordinated strategy of organizational influence to achieve implementation success despite these barriers. Our empirical analysis also found that technology implementation and …

Wireless energy and information transmission in FSO and RF-FSO links

2018

We propose and analyze a wireless energy and information transmission scheme in free-space optical (FSO) links. The results are presented for both quasi-static and fast-fading conditions. We derive closed-form expressions for throughput, outage probability, and optimal power allocation optimizing the system throughput/outage probability. Finally, we complement the FSO link with an additional radio frequency (RF) link to create a hybrid RF-FSO system and reduce the system outage probability. The results show that joint implementation of the RF and FSO links leads to considerable performance improvement, compared to the cases with only FSO-based communication.
