Narratives of identity in adopted adolescents: interview analysis

2016

Aim of the study The aim of the study was to examine the essential aspects of the process of shaping the identity of adopted persons. Subject or material and methods In the study a qualitative method of narrative interview was used. Results The results of the study were then analyzed in terms of self-awareness, family relations and wider social relations, which were described by other adoption researchers as the important factors in the shaping of the adoptive identity. Discussion Analysis of the narratives’ content allowed to establish that in the period of early and late adolescence other essential and vitally important issues play a dominant role in shaping the adoptee’s identity. This a…

Should conference pricing mechanisms incorporate options?

2016

The provision of many services is often characterized by demand uncertainty, as, at the time of purchase, consumers may not be completely informed about their valuation for the service or the possibility to utilize the service when it will actually be provided. For such reason, service providers implement several pricing mechanisms to maximize their profits in presence of consumer uncertainty and heterogeneity. A commonly adopted mechanism is intertemporal price discrimination, under which service providers charge different prices to consumers buying at different times. For instance, a lower price is usually offered to consumer buying early in advance, whereas higher price is practiced to l…

A metamodelling-based approach for method fragment comparison

2006

Several different approaches to Situational Method Engineering exist. They differ in terms of the primary element of the paradigm: the method fragment definition. Here, we introduce four method fragment definitions from the literature and compare their metamodels according to structural and functional criteria. The structural comparison showed a general alignment of some concepts that are sometimes referred with different names while the study of the compositional aspects results in evidence of substantial differences.

New trends in teacher’s education. Educational placement of the adopted child

2014

In Italy, the number of adopted school-age children is increasing. According to Commission of Intercountry Adoption (2013), 3106 children were adopted , 47.5% of them are between 5 and 9 years old. The present action-research aims to explore the spread of good approaches in schools in terms of welcoming of adopted children. For this purpose 268 teachers of primary schools were involved to analyze the social representation about adopted children and their family. The results show a semplified vision of the adoptive family, which is described as heroic family or, on the contrary, as an a family with difficulty.

Teachers' Representations on Adoptive Families and Educational Practices: New Challenges in Teachers' Preparation

2016

ABSTRACTIn Italy, as in Europe, the number of internationally adopted school-aged children is increasing. The school is the first place where they can meet their new context, enabling good achievement of the whole integration and adoption processes. The research uses a qualitative method to explore the representations and the strategies that guide the educational work of 268 teachers of eight primary schools in relation to the adoptive family. ATLAS.ti 7.0 software was used. The results show an ambivalent representation of the adoptive family, which is reflected in the contents and strategy used by teachers to address issues of adoption.

On first exit times and their means for Brownian bridges

2017

For a Brownian bridge from $0$ to $y$ we prove that the mean of the first exit time from interval $(-h,h), \,\, h>0,$ behaves as $O(h^2)$ when $h \downarrow 0.$ Similar behavior is seen to hold also for the 3-dimensional Bessel bridge. For Brownian bridge and 3-dimensional Bessel bridge this mean of the first exit time has a puzzling representation in terms of the Kolmogorov distribution. The result regarding the Brownian bridge is applied to prove in detail an estimate needed by Walsh to determine the convergence of the binomial tree scheme for European options.

Evaluation of Insurance Products with Guarantee in Incomplete Markets

2008

Abstract Life insurance products are usually equipped with minimum guarantee and bonus provision options. The pricing of such claims is of vital importance for the insurance industry. Risk management, strategic asset allocation, and product design depend on the correct evaluation of the written options. Also regulators are interested in such issues since they have to be aware of the possible scenarios that the overall industry will face. Pricing techniques based on the Black & Scholes paradigm are often used, however, the hypotheses underneath this model are rarely met. To overcome Black & Scholes limitations, we develop a stochastic programming model to determine the fair price of the mini…

Designing and pricing guarantee options in defined contribution pension plans

2015

Abstract The shift from defined benefit (DB) to defined contribution (DC) is pervasive among pension funds, due to demographic changes and macroeconomic pressures. In DB all risks are borne by the provider, while in plain vanilla DC all risks are borne by the beneficiary. However, for DC to provide income security some kind of guarantee is required. A minimum guarantee clause can be modeled as a put option written on some underlying reference portfolio and we develop a discrete model that selects the reference portfolio to minimize the cost of a guarantee. While the relation DB–DC is typically viewed as a binary one, the model shows how to price a wide range of guarantees creating a continu…
