Use of a Parallel-Emic Research Model and Key-Word-In-Context Indexing Tool to Develop an Instructional Exercise to Promote Student Global Mindedness

ABSTRACT

Educators have long sought how to prepare students to develop a global mind set and to work under conditions of complexity and uncertainty common in many world markets. The purpose of this study was to support educators in this cause by providing them with a “hands-on” exercise readily adaptable across the business curriculum to identify how culture shapes business concepts/practices of interest. Details are presented in a step-by-step procedure based upon a recognized “parallel-emic” research model developed to study cross-cultural differences to ensure analytical rigor. A Key-Word-In-Context (KWIC) indexing tool was employed to add precision and efficiency to the search process to help students readily identify common (etic-derived) and unique factors (emic-specific) shaping business concepts/practices cross-culturally.     

Fragmented networks and transnational entrepreneurship: Building strategies to prosper in challenging surroundings

Transnational entrepreneurship studies highlight the importance of personal profiles, institutions, and networks in creating and succeeding in this type of entrepreneurship. Even so, less is known about migrants whose networks are fragmented and closed, facing challenging environments at home and abroad. This paper aims to study the attributes of transnational entrepreneurs with small and fragmented networks, from post-conflict environments, who can perform an important role in the socioeconomic development and internationalization level of their countries of origin due to the cross border mobilization of resources they encourage. For that reason, the specific case of Colombian transnational entrepreneurs who have been able to overcome those obstacles with their transnational business is analyzed with the intention of understanding how they manage those shortcomings when engaging in transnational entrepreneurship. In aiming to obtain a deeper understanding of their characteristics, similitudes, differences, and motivations, the research uses multiple case studies. The main findings suggest that transnational entrepreneurs form purposeful–strategic networks to compensate their lack of amalgamated social systems, and that they have special qualities that distinguish them from other Colombian migrants and transnational entrepreneurs. Moreover, Colombian transnational entrepreneurs focus their business in the international market, using strategically their knowledge of both the local and foreign environment, while their main interest to do so is not altruistic but business oriented. Governments from post-conflict countries should promote transnational entrepreneurship while facilitating network formation and institutional trust through diverse strategies. Finally, implications for further research are drawn.

The Employment and Earnings Gaps between Natives and Immigrants in the UK between 1981 and 2006

We exploit the sizeable and long Lifetime Labour Market Database (LLMDB) to estimate the immigrant–native employment gap across gender, across continents of nationality and across lengths of stay in the UK between 1981 and 2006. These estimates are a novel contribution, as estimates for men and women are scarce in the literature and estimates across immigrants’ origins and lengths of stay are as yet unavailable. Furthermore, we estimate the employment gap as the differential in the number of employed weeks in the year between immigrants and natives, which has not been done before – this contrasts with the employment probability gap usually estimated in the literature. We also estimate the immigrant–native earnings gap across gender, across the entire earnings distribution, across continents of nationality and across lengths of stay. Estimates across the earnings distribution are also a novel contribution, as these are also as yet unavailable in the literature. Our main conclusion is that both the immigrant–native employment and earnings gaps vary across gender, continents of nationality and lengths of stay. Immigrant women earn more than native women throughout the distribution. The earnings gap is positive throughout for females: smaller at the bottom, larger at the top and relatively constant in the middle of the distribution. In contrast, it increases monotonically across the distribution for males: it is negative at the bottom and positive at the top. In the main, immigrants from Africa, Asia and the Middle East, Central and South America, and Eastern Europe suffer larger employment and earnings penalties, which are reduced as their length of stay increases. In contrast, immigrants from North America have a more favourable labour market experience.     

Neural network approximation for superhedging prices

This article examines neural network-based approximations for the superhedging price process of a contingent claim in a discrete time market model. First we prove that the α-quantile hedging price converges to the superhedging price at time 0 for α tending to 1, and show that the α-quantile hedging price can be approximated by a neural network-based price. This provides a neural network-based approximation for the superhedging price at time 0 and also the superhedging strategy up to maturity. To obtain the superhedging price process for $t>0$, by using the Doob decomposition, it is sufficient to determine the process of consumption. We show that it can be approximated by the essential supremum over a set of neural networks. Finally, we present numerical results.     

Ecotourism branding in protected areas of Iran: Using an efficient hybrid multi-criteria decision-making method model

Ecotourism, as a nature-based sustainable tourism, raises awareness about the protection of natural and cultural landscape values. This study aims to determine the ecotourism criteria to develop strategies for a sustainable ecotourism branding in Golestan, located in the northeast of Iran. To reach this aim, Strengths-Weaknesses-Opportunities-Threats (SWOT) analysis, multi-criteria decision-making methods consisting of Analytic Hierarchy Process (AHP), and Best and Worst Method (BWM) were integrated. The most appropriate ecotourism strategies for the branding of the study area were ranked according to their priorities. The results of this study reveal that among the 5 main and 20 sub ecotourism criteria, “having natural protected areas,” which is an opportunity, and “having ecological values,” which is a strength, were determined as the highest priority strategies for ecotourism branding. The methods and results of this quantitative-based research present an exemplary hybrid model that prioritizes the strategies required for branding ecotourism in similar protected areas.     

Optional projection under equivalent local martingale measures

We study optional projections of \({\mathbb{G}}\)-adapted strict local martingales on a smaller filtration \({\mathbb{F}}\) under changes of equivalent martingale measures. General results are provided as well as a detailed analysis of two specific examples given by the inverse Bessel process and a class of stochastic volatility models. This analysis contributes to clarify the absence of arbitrage opportunities of market models under restricted information.
