Virtual Reality in Marketing: A Framework, Review, and Research Agenda
2019
[EN] Marketing scholars and practitioners are showing increasing interest in Extended Reality (XR) technologies (XRs), such as virtual reality (VR), augmented reality (AR), and mixed reality (MR), as very promising technological tools for producing satisfactory consumer experiences that mirror those experienced in physical stores. However, most of the studies published to date lack a certain measure of methodological rigor in their characterization of XR technologies and in the assessment techniques used to characterize the consumer experience, which limits the generalization of the results. We argue that it is necessary to define a rigorous methodological framework for the use of XRs in ma…
Molecular and Insecticidal Characterization of a Cry1I Protein Toxic to Insects of the Families Noctuidae, Tortricidae, Plutellidae, and Chrysomelidae
2006
ABSTRACT The most notable characteristic of Bacillus thuringiensis is its ability to produce insecticidal proteins. More than 300 different proteins have been described with specific activity against insect species. We report the molecular and insecticidal characterization of a novel cry gene encoding a protein of the Cry1I group with toxic activity towards insects of the families Noctuidae, Tortricidae, Plutellidae, and Chrysomelidae. PCR analysis detected a DNA sequence with an open reading frame of 2.2 kb which encodes a protein with a molecular mass of 80.9 kDa. Trypsin digestion of this protein resulted in a fragment of ca. 60 kDa, typical of activated Cry1 proteins. The deduced sequen…
Bodies in the early childhood education classroom: a Bourdieusian analysis of curricular materials
2019
To our knowledge, no studies have used Bourdieu's theoretical contributions to frame investigations on how early childhood education (ECE) teaching materials construct body differences in a way that justifies gender inequality. For Bourdieu, the power to classify and grant properties and signs to subjects, does not reside only in the power to impose, but also in the degree to which the vision is anchored within reality. Therefore, the aims of this study is to assess the representation of the body in the curricular materials of ECE classrooms in 10 public centers, by means of quantitative content analysis and to provide, using Pierre Bourdieu's theoretical framework on the construction of th…
The Nature Tour Mobile Learning Application. Implementing the Mobile Application in Finnish Early Childhood Education Settings
2014
This paper explores the process and impact of the implementation of the Nature Tour mobile learning application in Finnish early childhood education settings. The interest is to explore whether the concept of Nature Tour mobile application meets the needs of early childhood education in field trips. The idea of the mobile application is to help recording and comparing nature observations as well as to arouse children’s interest in nature. The feasibility of the mobile application was evaluated through a theoretical framework, which includes the core aspects of mobile learning. The evaluation framework consists of two levels titled core level and medium level. Three of the core level aspects…
River bioassessment and the preservation of threatened species: Towards acceptable biological quality criteria
2010
Abstract A central objective of environmental management is to maintain biodiversity, including populations of threatened species. Freshwater ecosystems are increasingly assessed by their biotic properties, but whether the resulting classifications of biotic condition are sufficient to protect species with conservation status has received very little consideration. We used data from 225 reference and impacted river sites from Finland to examine whether the occurrence and abundance of threatened macroinvertebrate species (TS) are associated with a commonly used estimate of biological condition (Observed-to-Expected number of predicted taxa of macroinvertebrates or O/E-ratio of taxonomic comp…
Coordinates and Dynamics of the Relationships between Multinational Enterprises and Economic Development – A Theoretical Approach
2013
Abstract The paper aims to configure, based on the historical analyses of the theories regarding multinational enterprises and economic development (which, most of them, are unilateral, unidimensional and focused on just one theoretical background) a conceptual framework – subsumed to the idea of a matrix with variable architecture that integrates existing models – able to allow and favour the exhaustive and dynamic analysis of the relationships between multinational enterprises and economic development within the current and future spatial and temporal context – characterized by (enormous) complexity, turbulence and volatility.
The refugee entrepreneurship process from/in emerging economies
2021
The paper examines several refugee experiences in Mexico and presents their reasons for leaving their home countries. A gap in research is identifying the entrepreneurial process experienced by refugee entrepreneurs. We use the case study of 10 Latin American refugees in Mexico to propose a conceptual framework that describes the entrepreneurial process of refugee entrepreneurs. We have found that this process begins with the abandonment of the country of origin, followed by the traumatic experiences that caused flight and the difficulties they face in the pilgrimage to the host country. These events help shape the entrepreneurial intention of the refugees.
Obesity in the State of Mexico: Interfaces and concurrences
2014
AbstractIn Mexico, from the eighties decade, various documents were made, and in which is specified the health care of the population, including obesity, documents which have been enriched by documents recently issued yet. However, as a health problem, overweight and obesity have become major challenges, placing the country at first place in health statistics on worldwide. This situation is identified in the different zones of the country, such as in the case of the State of Mexico. The objective of this work was to understand the relationship between emission of health programs, its contents, and the performance of the participants. The present paper was documentary, retrospective, analyti…
CHALLENGES AND SOLUTIONS OF TVET QUALITY ASSURANCE IN MONGOLIA
2020
Technical and vocational education and training (TVET) makes a significant contribution to economic competitiveness in a knowledge-based economy. The main challenge for vocational education and training is to meet the changing skill needs in the labour market. In order to balance labour market supply and demand by constantly diversifying TVET customer base, it is necessary to increase the key role played by vocational education and training in economic competitiveness and social inclusion. The considerable economic growth in Mongolia does not have a positive impact on the creation of new jobs and poverty reduction. This implies that the Mongolian education sector was unable to produce requi…
Drivers and barriers of inter-municipal cooperation in health services – the Norwegian case
2018
Inter-municipal cooperation in service delivery is widespread, as is the notion that this type of cooperation is primarily driven by economies of scale. However, the empirical results appear to be ...
