  • Variants of biculturalism in migrant and host adolescents living in Italy and Spain: Testing the importance of life domains through the Relative Acculturation Extended Model.
    International Journal of Psychology, 2017
    Co-Authors: Tiziana Mancini, Marisol Navas, Lucía López-rodríguez, Benedetta Bottura
    Abstract:

    Several variants of biculturalism have recently been proposed (Schwartz, Birman, Benet-Martinez, & Unger, 2016). Nevertheless, few studies have identified different types of bicultural individuals, and no one has addressed the possibility that these types could depend on acculturation domains. By using the Relative Acculturation Extended Model (RAEM), this study aimed to explore if different variants of biculturalism could be individuated, and if some of these variants were sensitive to life domains. Four samples of migrant and host adolescents living in Italy (n = 173 and n = 186) and Spain (n = 139 and n = 156) answered a questionnaire about acculturation perceptions and preferences in central and peripheral life domains. Together with acculturation options consistent with Berry's (1997) Model (full-assimilation, full-separation and full-marginalisation), some variants of biculturalism emerged from the latent class analysis: full-high and full-low integration, which were not sensitive to life domains; and “alternate” acculturation options that were sensitive to life domains, with participants switching from their original culture to the host culture according to the peripheral and central domains. Acculturation options varied across the four samples, with Italians switching more from one culture to another, and Spanish adolescents being more full-high or full-low integrated.

  • Acculturation strategies and attitudes according to the Relative Acculturation Extended Model (RAEM): The perspectives of natives versus immigrants
    International Journal of Intercultural Relations, 2006
    Co-Authors: Marisol Navas, Antonio J. Rojas, María Del Carmen Cerón García, Pablo Pumares
    Abstract:

    Abstract The purpose of this work was to study acculturation of the African immigrant and host populations in an area in the southeast of Spain (Almeria), characterized by a high rate of immigration. A new acculturation Model, the Relative Acculturation Extended Model, RAEM [Navas, M., Pumares, P., Sanchez, J., Garcia, M. C., Rojas, A. J., Cuadrado, I., & Asensio, M. (2004).

Relative Acculturation Extended Model: New contributions with regard to the study of acculturation. International Journal of Intercultural Relations , 29 , 21–37], is used for this. This Model differentiates between the real and ideal planes of acculturation, that is, between the strategies that are actually put into practice and attitudes that are preferred. Moreover, the Model distinguishes seven spheres, or domains, of acculturation (political, work, economic, social, family, religious and ways of thinking), in which persons (immigrants and natives) adopt and prefer different acculturation options (strategies and attitudes). About 1523 persons (397 Maghrebis, 434 Sub-Saharans, 398 Spaniards who evaluated the Maghreb exogroup and 385 Spaniards who evaluated the Sub-Saharan exogroup), answered a questionnaire made expressly for the study. According to our predictions, immigrants and natives coincide in their choices for acculturation (“assimilation”) in the peripheral domains of the RAEM (work, economic); they also coincide in their acculturation attitudes in the social domain (“integration”); however, they differ enormously in the options preferred for the central spheres, or hard core, of the culture (e.g., family, religious, ways of thinking): While immigrants prefer “separation”, natives continue to prefer “assimilation”. Advantages of the RAEM division into domains of acculturation are discussed with regard to previous Models, as well as the implications for predicting inter-group conflict.

  • Relative Acculturation Extended Model (RAEM): New contributions with regard to the study of acculturation
    International Journal of Intercultural Relations, 2005
    Co-Authors: Marisol Navas, Antonio J. Rojas, María Del Carmen Cerón García, Pablo Pumares, J.a. Sánchez, Juan Pedro Solano Fernández
    Abstract:

    Abstract The worldwide volume and social relevance of migratory processes justify the need to study the psychological acculturation of the host and immigrant populations through a Model adapted to the social context in which they develop. Therefore, the main objective of this article is to carry out a review of some of the existing acculturation Models (e.g., Berry, Kim, Power, Young, & Bujaki. (1989). Applied Psychology, 38, 185–206; Bourhis, Moise, Perreault, & Senecal. (1997). International Journal of Psychology, 32(6), 269–386; Piontkowski, Florack, Hoelker, & Obdrzalek. (2000). International Journal of Intercultural Relations, 24, 1–26), ending up with a proposal for a Relative Acculturation Extended Model (RAEM). This theoretical framework gathers some elements from previous Models and adds some new ones in order to offer new explanations for the acculturation strategies and attitudes preferred by both the native and immigrant populations. The most relevant contributions of the RAEM can be summarised as, on the one hand, the consideration of different acculturation domains (political, work, economic, family, social, religion and ways of thinking) and on the other, the differentiation between the acculturation strategies adopted in reality and the acculturation attitudes ideally preferred by the groups in contact. This Model also takes into account the ethnocultural origin of immigrants and some variables predicting and modulating their acculturation strategies and attitudes.

  • The GO-SSA Extended Model for all-incidence sea clutter Modeling
    2014
    Co-Authors: Sébastien Angelliaume, V. Fabbro, Gabriel Soriano, Charles-antoine Guérin
    Abstract:

    The GO-SSA-Extended Model is an extension of the physical GO-SSA Model with augmented range of validity. It is obtained through the addition of extra empirical terms. This improved Model can predict the backscatter reflectivity from the sea surface for the full range of grazing and azimuthal angles. This Model compares favorably with Xband experimental measurements (VV and HH polarization) acquired by the ONERA and DSTO.

  • coronary calcium score improves the estimation for pretest probability of obstructive coronary artery disease and avoids unnecessary testing in individuals at low extreme of traditional risk factor burden validation and comparison of confirm score an
    BMC Cardiovascular Disorders, 2018
    Co-Authors: Minghui Wang, Xiujun Zhou, Jia Zhou, Hong Zhang, Ying Zhang
    Abstract:

    Reliability of Models for estimating pretest probability (PTP) of obstructive coronary artery disease (CAD) has not been investigated in individuals at low extreme of traditional risk factor (RF) burden. Thus, we sought to validate and compare CONFIRM score and Genders Extended Model (GEM) among these individuals. We identified symptomatic individuals with 0 or 1 RF who underwent coronary calcium scan and coronary computed tomographic angiography (CCTA). Follow-up clinical data were also recorded. PTP of obstructive CAD for every individual was estimated according to CONFIRM score and GEM, respectively. Area under the receiver operating characteristic curve (AUC), integrated discrimination improvement (IDI), net reclassification improvement (NRI) and Hosmer–Lemeshow (H-L) test were used to assess the performance of Models. There were 1201 individuals with 0 RF and 2415 with 1 RF. The AUC for GEM was significantly larger than that for CONFIRM score, no matter in individuals with 0 (0.843 v.s. 0.762, p < 0.0001) or 1 (0.823 v.s. 0.752, p < 0.0001) RF. Compared to CONFIRM score, GEM demonstrated positive IDI (5% in individuals with 0 RF and 8% in individuals with 1 RF), positive NRI (41.50% in individuals with 0 RF and 40.19% in individuals with 1 RF), better prediction of clinical events and less discrepancy between observed and predicted probabilities, resulting in a significant decrease of unnecessary testing, especially in negative individuals. In individuals at low extreme of traditional RF burden of CAD, the addition of coronary calcium score provided a more accurate estimation for PTP and application of GEM instead of CONFIRM score could avoid unnecessary testing.

  • mbse foundations for Extended Model based systems engineering across system lifecycle
    INCOSE International Symposium, 2016
    Co-Authors: Manas Bajaj, Alex Phung, Anshu Dwivedi, Rose Yntema, Dirk Zwemer, Amit Kumar, Manoj Waikar
    Abstract:

    This paper presents an approach for next-generation Model-based systems engineering across the system lifecycle, labelled MBSE++. This approach is based on the idea of a Total System Model that serves and evolves as the digital blueprint of a system through its lifecycle. The fundamental principles of MBSE++ are presented in this paper, including the use of decentralized and heterogeneous engineering Models and repositories, spectrum of fine-grained Model-based connections, unified representation of the system independent of the location of Models, Model transformations, comparisons, and synchronization to communicate between disciplines, and visualization and analytics for effective decision making. The motivation for each of the MBSE++ principles is presented, followed by a description of use cases. The use cases are exemplified using Syndeia, a MBE/MBSE platform developed by Intercax.
