Comparison of Explicit and Implicit Methods of Cross-Cultural Learning in an International Classroom
Resumo:
The paper addresses a gap in the literature concerning the difference between enhanced and not enhanced cross-cultural learning in an international classroom. The objective of the described research was to clarify if the environment of international classrooms could enhance cross-cultural competences significantly enough or if additional focus on cross-cultural learning as an explicit objective of learning activities would add substantially to the experience. The research question was defined as “how can a specific exercise focused on cross-cultural learning enhance the cross-cultural skills of university students in an international classroom?”. Surveys were conducted among interna- tional students in three leading Central-European Universities in Lithuania, Poland and Hungary to measure the increase of their cross-cultural competences. The Lithuanian and Polish classes were composed of international students and concentrated on International Management/Business topics (explicit method). The Hungarian survey was done in a general business class that just happened to be international in its composition (implicit method). Overall, our findings prove that the implicit method resulted in comparable, somewhat even stronger effectiveness than the explicit method. The study method included the analyses of students’ individual increases in each study dimension and construction of a compound measure to note the overall results. Our findings confirm the power of the international classroom as a stimulating environment for latent cross-cultural learning even without specific exercises focused on cross-cultural learning itself. However, the specific exercise did induce additional learning, especially related to cross-cultural awareness and communication with representatives of other cultures, even though the extent of that learning may be interpreted as underwhelming. The main conclusion from the study is that the diversity of the students engaged in a project provided an environment that supported cross-cultural learning, even without specific culture-focused reflections or exercises.

Following the approval of the 2030 Agenda for Sustainable Development in 2015, sustainability became a hotly debated topic. In order to build a better and more sustainable future by 2030, this agenda addressed several global issues, including inequality, climate change, peace, and justice, in the form of 17 Sustainable Development Goals (SDGs), that should be understood and pursued by nations, corporations, institutions, and individuals. In this thesis, we researched how to exploit and integrate Human-Computer Interaction (HCI) and Data Visualization to promote knowledge and awareness about SDG 8, which wants to encourage lasting, inclusive, and sustainable economic growth, full and productive employment, and decent work for all. In particular, we focused on three targets: green economy, sustainable tourism, employment, decent work for all, and social protection. The primary goal of this research is to determine whether HCI approaches may be used to create and validate interactive data visualization that can serve as helpful decision-making aids for specific groups and raise their knowledge of public-interest issues. To accomplish this goal, we analyzed four case studies. In the first two, we wanted to promote knowledge and awareness about green economy issues: we investigated the Human-Building Interaction inside a Smart Campus and the dematerialization process inside a University. In the third, we focused on smart tourism, investigating the relationship between locals and tourists to create meaningful connections and promote more sustainable tourism. In the fourth, we explored the industry context to highlight sustainability policies inside well-known companies. This research focuses on the hypothesis that interactive data visualization tools can make communities aware of sustainability aspects related to SDG8 and its targets. The research questions addressed are two: "how to promote awareness about SDG8 and its targets through interactive data visualizations?" and "to what extent are these interactive data visualizations effective?".

OBJECTIVE: To describe the coping strategies used by the relatives of patients hospitalized in an intensive care unit. METHODS: This is a descriptive study that uses a convenience sample and both qualitative and quantitative methods. The study was conducted at a tertiary university hospital in Brazil. Participants included 41 relatives who were selected during the first 96 hours of patient hospitalization in the intensive care unit. RESULTS: The participants reported that they more frequently used Coping Strategies Based on the Stressor, followed by Religiosity/Fantasy Thinking and Seeking for Social Support. There was a statistically significant relationship (P <.01) between the use of the strategy Seeking for Social Support and elevated Acute Physiology, Age, and Chronic Health Evaluation 11 scores. Qualitative analysis allowed a clearer understanding of the relation between the patient`s condition and changes in the coping strategies used by the patient`s relatives. CONCLUSION: This study describes the coping strategies used by patients` relatives during the early hospitalization period. This investigation allowed for a better understanding of the relatives` psychologic aspects and their relation with the patient`s clinical condition. The results shall assist the design of specific interventions directed at facilitating positive coping responses on the part of relatives. (Heart Lung (R) 200 38:217-227.)

Using the domestic group as the privileged unit of analysis, this article provides a study of social change based on the case study of a town in Northeastern Portugal, covering the period between 1944-1994. The article combines different types of sources (ethnographic inquiry, documents from the Parochial Archives) and underscores the importance of the complementary use of qualitative and quantitative methods for a dynamic approach to the study of the domestic group.

This paper presents an embryo of a literary guide on the Carnation Revolution to be explored for educational historical excursions other than leisure and tourism. We propose a historical trail through the centre of Lisbon, city of the Carnation Revolution, called Walk through the Revolution. The trail aims to reinforce collective memory about the major events that occurred in the early moments leading to the coup. The trail is made up by nine places of rememberance, for which literary excerpts are suggested and which are supported by a digital research procedure. A set of seven fixed and observer-independent categories are used to analyse the literary contents of 23 literary works published up to 2013. These literary works refer to events that happened between the eve of April 25 and May 1, 1974. At the same time, literary descriptions are explored using a spatial approach in order to define the literary geography of the most iconic military actions and popular demonstrations that occurred in Lisbon and the surroundings. The literary geography and the cartography of the historical events are then compared. Data analysis and visualization benefit from the use of standardised and quantitative methods, including basic statistics and geographic information systems.

The occupational risks in the nanotechnology research laboratories are an important topic since a great number of researchers are involved in this area. The risk assessment performed by both qualitative and quantitative methods is a necessary step for the management of the occupational risks. Risk assessment could be performed by qualitative methods that gather consensus in the scientific community. It is also possible to use quantitative methods, based in different technics and metrics, as indicative exposure limits are been settled by several institutions. While performing the risk assessment, the information on the materials used is very important and, if it is not updated, it could create a bias in the assessment results. The exposure to TiO2 nanoparticles risk was assessed in a research laboratory using a quantitative exposure method and qualitative risk assessment methods. It was found the results from direct-reading Condensation Particle Counter (CPC) equipment and the CB Nanotool seem to be related and aligned, while the results obtained from the use of the Stoffenmanager Nano seem to indicate a higher risk level.

The objective of this study is to review the health promotion interventions on spanish youths published in Spanish in the 1995-2000 period and to describe them in accordance with the scope within which they have been carried out, the topics addressed, the methodology, the evaluation design used and the results obtained. Two hundred and fourteen intervention were identified. Illegal drugs were the topic on which the largest number of interventions were focused (29.8%), followed by alcohol (15.9%), the risk-related sexual behaviours (14.6%) and leisure time (12.6%). The activities carried out most often were: participation-based educational methods (30.7%), explanatory education methods (11.5%) and the preparation of educational materials (11%). In 80.8% of the cases, some evaluation of the health promotion activities was found. The type of evaluation employed most often was the process evaluation (73.7%), and the medium-long term results evaluation being those employed the least (2.2%). The evaluation methodologies used most often were questionnaires (28.2%). A combination of qualitative and quantitative methods was employed in 13.2% of the cases. The four interventions in which the medium-long term impact was gauged had the purpose of preventing and reducing cigarette smoking and/or drinking and or marijuana smoking, all of these initiatives achieving a reduction in cigarette smoking. In conclusion, it seems necessary to improve the design of the evaluations of the health promotion initiatives addressed to young people in Spain and to increase the dissemination of the same by way of their publication.

The achievable region approach seeks solutions to stochastic optimisation problems by: (i) characterising the space of all possible performances(the achievable region) of the system of interest, and (ii) optimisingthe overall system-wide performance objective over this space. This isradically different from conventional formulations based on dynamicprogramming. The approach is explained with reference to a simpletwo-class queueing system. Powerful new methodologies due to the authorsand co-workers are deployed to analyse a general multiclass queueingsystem with parallel servers and then to develop an approach to optimalload distribution across a network of interconnected stations. Finally,the approach is used for the first time to analyse a class of intensitycontrol problems.

Re-licensing requirements for professionals that move across borders arewidespread. In this paper, we measure the returns to an occupationallicense using novel data on Soviet trained physicians that immigrated toIsrael. An immigrant re-training assignment rule used by the IsraelMinistry of Health provides an exogenous source of variation inre-licensing outcomes. Instrumental variables and quantile treatmenteffects estimates of the returns to an occupational license indicate excesswages due to occupational entry restrictions and negative selectioninto licensing status. We develop a model of optimal license acquisitionwhich suggests that the wages of high-skilled immigrant physicians in thenonphysician sector outweigh the lower direct costs that these immigrantsface in acquiring a medical license. Licensing thus leads to lower averagequality of service. However, the positive earnings effect of entry restrictionsfar outweighs the lower practitioner quality earnings effect that licensinginduces.

In this paper we propose a subsampling estimator for the distribution ofstatistics diverging at either known rates when the underlying timeseries in strictly stationary abd strong mixing. Based on our results weprovide a detailed discussion how to estimate extreme order statisticswith dependent data and present two applications to assessing financialmarket risk. Our method performs well in estimating Value at Risk andprovides a superior alternative to Hill's estimator in operationalizingSafety First portofolio selection.
