Island diasporas: Perceptions of Indo-Caribbean protégés regarding the effects of their cross-cultural mentoring experiences in the United States

Mentoring is defined as an "intense caring relationship in which persons with more experience work with less experienced persons to promote both professional and personal development" (Caffarella, 1992, p. 38). It is "a powerful emotional, and passionate interaction whereby the mentor and protégé experience...intellectual growth and development" (Galbraith & Zelenak, 1991, p. 126). In cross-cultural mentoring, mentors and protégés from different cultures confront social and cultural identities, goals, expectations, values, and beliefs (Cross & Lincoln, 2005) to "achieve a higher level of potency in education and society" (Mullen, 2005, p. 6). Cross-cultural mentoring research explores attitudes, behaviors, linguistics and motivators of the more visible racial and ethnic groups in the U.S. (Elmer, 1986, Ulmer, 2008). The cross-cultural mentoring experiences of Indo-Caribbeans in the U.S. are obscured from the research despite their rich socio-historic culture. The purpose of this phenomenological study was to explore the perceptions of Indo-Caribbean protégés regarding the effects of their cross-cultural mentoring experiences in the United States. Phenomenology is "the systematic attempt to uncover and describe...the internal meaning structures, of lived experience [by studying the] particulars or instances as they are encountered" (Van Manen, 1990, p. 10). Criterion and snowball sampling were used to recruit 15 participants. A semi-structured interview guide was used to gather data and Creswell's (2007) simplified version of Moustakas's (1994) Modification of the Stevick-Colaizzi-Keen Method of Analysis of Phenomenological Data was used to analyze the data. Three themes emerged: (a) "Sitting at the feet of gurus" taught protégés how to accept guidance, (b) Guru-Shishya: Learning and Discipleship, ways that protégés perceived mentors' guidance related to work, skill acquisition, and social or emotional support, and (c) Samavartan sanskar: Building Coherence, helped protégés understand, manage and find meaning. Protégés' goals and professional expectations determined what they wanted from cross-cultural mentoring relationships and what they were willing to endure within those relationships. Since participants valued achievement and continuous improvement, mentor support was integral to making meaning and developing a sense of coherence in their lives. Implications regarding cross-cultural mentoring relationships together with recommendations for future research conclude the study.

An investigation of parents' and children's beliefs of early literacy acquisition from a cross -cultural perspective

It has been reported that the cultural-historical experiences of ethnic group members can play a role in the literacy beliefs of those members. Socioeconomic conditions can also influence the belief system of the groups' constituents. This study investigated parents' and children's beliefs pertaining to early literacy acquisition as related to the ethnicity and socioeconomic status (SES) of the participants. The objectives were to determine (a) the differential patterns regarding emergent literacy and traditional skills approaches as they interact with ethnicity and SES and (b) the correspondence between parents and children's beliefs about literacy acquisition. ^ The study was conducted with 152 parents (38 low-income Hispanic, 38 middle-income Hispanic, 38 low-income African-American, and 38 middle-income African-American) and 36 of their 3-, 4-, or 5-year-old children (18 male and 18 female). ^ The parents were asked to check those items with which they agreed on a survey that consisted of an equal number of items from the traditional skills-based and emergent literacy orientations. These responses were used to determine the differences and interaction by ethnicity and SES. The children responded to open-ended questions related to the instruction of reading and writing skills. The parents' responses and children's answers were compared to ascertain the matching parent-child dyads by ethnicity and SES. ^ An item analysis was conducted to strengthen the internal reliability consistency coefficient of the traditional skills-based and emergent literacy scales as measured by the Cronbach Alpha. ^ A two-way multivariate analysis of variance (MANOVA) revealed a significant difference in traditional skill-based beliefs for the low-income African-American and Hispanic parents. There were no significant findings for the parents' traditional skill based or emergent literacy beliefs based on ethnicity, for the interaction between ethnicity and SES, or for the relationship between parents' and children's literacy beliefs by ethnicity and SES. ^ It can be concluded that low-income African-American and Hispanic parents believe in the traditional skills approach, indicating that these parents find it necessary for children to have sufficient school readiness skills prior to learning to read or write. In addition, the parent and child dyads had a strong tendency toward emergent literacy beliefs. ^

Computer assisted synthesis and in-vitro cytotoxic evaluation of new pyrazole-fused isoquinolinoquinones derivatives as PI3K receptor antagonist with promising antitumoral activity

The importance of pyrazole and isoquinoline-5,8-dione scaffolds in medical chemistry is underlined by the high number of drugs currently on trading that contains these active ingredients. Due to their cytotoxic capability, the interest of medicinal chemists in these heterocyclic rings has grown exponentially especially, for cancer therapy. In this project, the first synthesis of pyrazole-fused isoquinoline-5,8-diones has been developed. 1,3-Dipolar cycloaddition followed by oxidative aromatization, established by our research group, has been employed. Screening of reaction conditions and characterization studies about the regioselectivity have been successfully performed. A remote control of regioselectivity, to achieve the two possible regioisomers has been accomplished. Through Molecular Docking studies, Structure-Activity relationship of differently substituted scaffolds containing our central core proved that a family of PI3K inhibitors have been discovered. Finally, in order to verify the promising antitumor activity, a first test of cell viability in vitro on T98G cell line of a solid brain tumor, the Glioblastoma Multiforme, showed cytotoxic inhibition comparable to currently trade anticancer drugs.

Accuracy of computer-aided design/computer-assisted manufacture (CAD/CAM) fabricated dental restorations: a comparative study

Introduction: Computer-Aided-Design (CAD) and Computer-Aided-Manufacture (CAM) has been developed to fabricate fixed dental restorations accurately, faster and improve cost effectiveness of manufacture when compared to the conventional method. Two main methods exist in dental CAD/CAM technology: the subtractive and additive methods. While fitting accuracy of both methods has been explored, no study yet has compared the fabricated restoration (CAM output) to its CAD in terms of accuracy. The aim of this present study was to compare the output of various dental CAM routes to a sole initial CAD and establish the accuracy of fabrication. The internal fit of the various CAM routes were also investigated. The null hypotheses tested were: 1) no significant differences observed between the CAM output to the CAD and 2) no significant differences observed between the various CAM routes. Methods: An aluminium master model of a standard premolar preparation was scanned with a contact dental scanner (Incise, Renishaw, UK). A single CAD was created on the scanned master model (InciseCAD software, V2.5.0.140, UK). Twenty copings were then fabricated by sending the single CAD to a multitude of CAM routes. The copings were grouped (n=5) as: Laser sintered CoCrMo (LS), 5-axis milled CoCrMo (MCoCrMo), 3-axis milled zirconia (ZAx3) and 4-axis milled zirconia (ZAx4). All copings were micro-CT scanned (Phoenix X-Ray, Nanotom-S, Germany, power: 155kV, current: 60µA, 3600 projections) to produce 3-Dimensional (3D) models. A novel methodology was created to superimpose the micro-CT scans with the CAD (GOM Inspect software, V7.5SR2, Germany) to indicate inaccuracies in manufacturing. The accuracy in terms of coping volume was explored. The distances from the surfaces of the micro-CT 3D models to the surfaces of the CAD model (CAD Deviation) were investigated after creating surface colour deviation maps. Localised digital sections of the deviations (Occlusal, Axial and Cervical) and selected focussed areas were then quantitatively measured using software (GOM Inspect software, Germany). A novel methodology was also explored to digitally align (Rhino software, V5, USA) the micro-CT scans with the master model to investigate internal fit. Fifty digital cross sections of the aligned scans were created. Point-to-point distances were measured at 5 levels at each cross section. The five levels were: Vertical Marginal Fit (VF), Absolute Marginal Fit (AM), Axio-margin Fit (AMF), Axial Fit (AF) and Occlusal Fit (OF). Results: The results of the volume measurement were summarised as: VM-CoCrMo (62.8mm3 ) > VZax3 (59.4mm3 ) > VCAD (57mm3 ) > VZax4 (56.1mm3 ) > VLS (52.5mm3 ) and were all significantly different (p presented as areas with different colour. No significant differences were observed at the internal aspect of the cervical aspect between all groups of copings. Significant differences (p< M-CoCrMo Internal Occlusal, Internal Axial and External Axial 2 ZAx3 > ZAx4 External Occlusal, External Cervical 3 ZAx3 < ZAx4 Internal Occlusal 4 M-CoCrMo > ZAx4 Internal Occlusal and Internal Axial The mean values of AMF and AF were significantly (p M-CoCrMo and CAD > ZAx4. Only VF of M-CoCrMo was comparable with the CAD Internal Fit. All VF and AM values were within the clinically acceptable fit (120µm). Conclusion: The investigated CAM methods reproduced the CAD accurately at the internal cervical aspect of the copings. However, localised deviations at axial and occlusal aspects of the copings may suggest the need for modifications in these areas prior to fitting and veneering with porcelain. The CAM groups evaluated also showed different levels of Internal Fit thus rejecting the null hypotheses. The novel non-destructive methodologies for CAD/CAM accuracy and internal fit testing presented in this thesis may be a useful evaluation tool for similar applications.

Computer in Unterricht und Ausbildung. Neue Anforderungen an Lehrer, Ausbilder und Trainer?

Die Nützlichkeit des Einsatzes von Computern in Schule und Ausbildung ist schon seit einigen Jahren unbestritten. Uneinigkeit herrscht gegenwärtig allerdings darüber, welche Aufgaben von Computern eigenständig wahrgenommen werden können. Bewertet man die Übernahme von Lehrfunktionen durch computerbasierte Lehrsysteme, müssen häufig Mängel festgestellt werden. Das Ziel der vorliegenden Arbeit ist es, ausgehend von aktuellen Praxisrealisierungen computerbasierter Lehrsysteme unterschiedliche Klassen von zentralen Lehrkompetenzen (Schülermodellierung, Fachwissen und instruktionale Aktivitäten im engeren Sinne) zu bestimmen. Innerhalb jeder Klasse werden globale Leistungen der Lehrsysteme und notwendige, in komplementärer Relation stehende Tätigkeiten menschlicher Tutoren bestimmt. Das dabei entstandene Klassifikationsschema erlaubt sowohl die Einordnung typischer Lehrsysteme als auch die Feststellung von spezifischen Kompetenzen, die in der Lehrer- bzw. Trainerausbildung zukünftig vermehrt berücksichtigt werden sollten. (DIPF/Orig.)

The magical realism of metaphor: cross-cultural comparisons in use of metaphor in cognition

Three experiments explore the hypothesis that due to linguistic and cultural factors, metaphor usage – or thinking in terms of what something is like – differs across cultures. In Experiment 1, a lexical decision task supported the hypothesis that perception of what something is like tends to be faster and more automatic in Latino participants than in Anglo participants. In Experiment 2, Anglo participants were less able to solve a problem framed metaphorically than Latino participants were. To ensure that a preference for metaphor is not applicable to all bilingual populations, we included bilingual Asian participants in Experiment 3. In this study, Latino participants rated arguments presented with metaphors as more persuasive than arguments that did not have metaphors, while the opposite pattern was found in Anglo and Asian participants. The findings from these three studies provide support for the hypothesis that the Latino preference for metaphor is real and pervasive. Implications in the domains of education and public health interventions are briefly noted.

Feeding students’ creativity with language arts: a project developed at ESEV (2013-15)

Children live at a time when the rapid turnover of information and the ongoing changes in the technological, social, cultural, political and economic spheres make it more difficult for teachers to prepare lessons that enhance students’ interest and motivation. There is so much to be learnt outside of the classroom’s four walls that traditional methods of teaching may not be the most effective way to teach today’s learners. When it comes to classes of Portuguese language, teachers are faced with the challenge of teaching culture, literature, grammar and skills such as reading, writing and speaking in a way that involves students as active participants, that is, in a way that engages while also instructing. It means that several strategies need to be adopted, from games to the use of new technologies or, among others, an interdisciplinary approach with maths, (social) sciences and arts, for instance. In an attempt to motivate gifted and talented children that were attending elementary school in a small town near Viseu, in Portugal, The School of Education of the Polytechnic Institute of Viseu was asked to be part of a project in 2013, in a collaborative partnership that proved successful and that was re-enacted in 2015. It is in light of the above that, in this paper, we aim to: a) describe the support that the School of Education provided to these participants, children who were between six and fourteen, by presenting Portuguese language activities that intended to stimulate creative thinking and artistic production; and b) discuss the results of the project, by analysing the students’ productions across verbal and visual modes (ie. script writing and dubbing an excerpt of an animation film, interviews, news reports, drawings, the creation and recitation of poems…). Future activities are on the table, meaning that the School of Education’s commitment to feeding the students’ creativity has shown promising results. Creativity in Portuguese classes is not a guarantee of success but it certainly is food for thought.

Sexual dysfunction in breast cancer survivors: cross-cultural adaptation of the Sexual Activity Questionnaire for use in Portugal

"Introduction: The increasing survivor population of breast cancer has shifted research and practice interests into the impacts of the disease and treatment in quality of life aspects. The lack of tools available in Portuguese to objectively evaluate sexual function led to the development of this study, which aimed to cross-culturally adapt and validate the Sexual Activity Questionnaire for use in Portugal. Material and Methods: The questionnaire was translated and back-translated, refined following face-to-face interviews with seven breast cancer survivors, and then self-administered by a larger sample at baseline and a fortnight later to test validity and reliability. Results: Following cognitive debriefing (n = 7), minor changes were made and the Sexual Activity Questionnaire was then tested with 134 breast cancer survivors. A 3-factor structure explained 75.5% of the variance, comprising the Pleasure, Habit and Discomfort scales, all yielding good internal consistency (Cronbach’s α > 0.70). Concurrent validity with the FACt-An and the BCPT checklist was good (Spearman’s r > 0.65; p-value < 0.001) and reliability acceptable (Cohen’s k > 0.444). The Sexual Activity Questionnaire allowed the identification of 23.9% of sexually inactive women, for whom the main reasons were lack of interest or motivation and not having a partner. Discussion: Patient-reported outcomes led to a more comprehensive and improved approach to cancer, tackling areas previously abandoned. Future research should focus on the validation of this scale in samples with different characteristics and even in the overall population to enable generalizability of the findings. Conclusion: The adapted Sexual Activity Questionnaire is a valid tool for assessing sexual function in breast cancer survivors in Portugal."

A cross-cultural study of somatic countertransference

Somatic countertransference is a valuable clinical tool in psychoanalytic practice, which provides the clinician with clues about the emerging, inter subjective and relational field of the analytic dyad. This thesis explores how somatic countertransference occurs and how best to work with from a cross-cultural perspective.

Cross-cultural team effectiveness for MBA students studying in an immersion program

We focus on cross-cultural team effectiveness for MBA students involvedin an immersion program, examining the development of knowledgeabout cultural traits, the challenges associated with teamwork, andfactors that promote or hinder team performance, based on qualitativeresults of a survey of 20 students who participated in the program. Keyobserved traits included; Indonesians were perceived to becollectivist/relationship, Australians were laid back, informal but taskfocused, and Americans were hard working and outspoken. Keychallenges faced by students included managing cultural differences,culturally embedded decision-making styles and communication/language hurdles. Team performance was facilitated by acknowledgingand addressing cultural issues from the start, not being ethnocentric,valuing team diversity, and focusing on task completion.
