Abstract

Shows how a sensitivity analysis of different mobility models was carried out in order to reach the best fit of simulation results to measured data. Simulated data were compared to both electrical (IV‐characteristics) and optical (excess charge carrier distribution) results. The simulations included both steady state and transient investigations on a temperature scale ranging from room temperature up to 150°C. Concerning lifetimes, a two‐trap Shockley‐Read‐Hall (SRH) recombination model was implemented into the simulation code to be able to model the local lifetime variations of the irradiated samples. At high carrier concentration, the overall dominating recombination process is the Auger process. From experimental data the Auger coefficients seem to be concentration dependent too, and in addition, proposes a temperature dependence to the Auger coefficient.

Abstract

Purpose

Obesity is a chronic disease and it is very important to determine the underlying factors at the early stage. Disturbance in eating behaviors may predict the obesity risk.

Design/methodology/approach

In the present study, it was aimed to investigate eating behavior of Turkish adults by using The Three-Factor Eating Questionnaire-R18 (TFEQ-R18) and to analyze the association between anthropometric measurements and socio-demographic factors.

Findings

Individuals composed of 698 males, aged 28.6 ± 10.3 years and 1,736 females, aged 25.1 ± 7.8 years. Demographic characteristics participants were obtained via a questionnaire. TFEQ-R18for assessing eating behavior was used. Results claim that the usage of TFEQ-R18 was appropriate for non-obese individuals (Cronbach’s α value 0.83 for underweight group (n = 180, 7.4%), 0.76 for normal group (n = 1604, 65.9%), 0.69 for overweight group (n = 492, 20.2%), 0.69 obese group (n = 158, 6.5%). Gender seems to effect emotional eating scores (p = 0.026) and employment status seem to affect all TFEQ-R18 sub-group dimensions (cognitive eating scores, p = 0.022, uncontrolled eating scores, p < 0.001, emotional eating scores, p < 0.001). Divorced individuals tend to have higher cognitive restraint scores (16.2 ± 3.7). Although, single people have higher emotional eating scores (7.5 ± 2.6) (p = 0.006). There is a positive correlation among waist–height ratio, waist and neck circumference and cognitive restraint and uncontrolled eating scores (p < 0.001). However, body weight and height correlate negatively with cognitive restraint scores (p < 0.001).

Originality/value

According to the authors’ knowledge, this study gives brief results for the usage of TFEQ-R18 and the ability to predict eating behaviors in the general population.

Abstract

The ability for learners to interact online via their avatars in a 3-D simulation space means that virtual worlds afford a host of educational opportunities not offered by other learning technology platforms, but their use also raises several pertinent issues that warrant consideration. This chapter reviews the educational use of virtual worlds from a design perspective. Virtual-world definitions are explored, along with their key educational characteristics. Different virtual-world environments are briefly contrasted, including Second Life, Active Worlds, Open Sim, and Minecraft. A wide variety of virtual-world uses in schools and universities are examined so as to understand their versatility. Key educational benefits of virtual worlds are distilled from the literature, such as the ability to facilitate 3-D simulations, role-plays, construction tasks, and immersive learning. Emergent issues surrounding the use of virtual worlds are also analyzed, including cognitive load, safety, and representational fidelity. One higher education and one school level vignette are provided in order to offer more detailed insight into the use of virtual worlds in practice. Recommendations for learning design and implementation are presented, based on the thematic analysis of contemporary virtual-worlds research.

Abstract

This essay provides an overview of key contemporary issues researched by scholars of Language Issues in Comparative and International Education. The authors present this scholarship around three main themes: L1-based multilingual education; language revitalization and education; and the power dynamics between dominant and non-dominant languages in educational settings. Research in all three themes challenges the view of monolingualism as the norm and invites the view that all languages are resources. These perspectives are relevant to the goals of educational development, particularly to equitable access to quality schooling. Recent research examines some stakeholders’ resistance to supporting and sustaining local languages and cultural practices. While language-in-education policy change may be slow, there are promising directions in research on how educators and communities exercise agency in transforming educational institutions to support plurilingualism and intercultural understandings. Scholars highlight the ideological, pedagogical, and policy-level supports needed for sustainable development of multiple languages, literacies and learning across contexts.

Abstract

This chapter reviews and synthesizes three major strands of recent research, alongside discipline-specific research design, from scholars of Language Issues in Comparative and International Education. The first strand is mixed methods research on the policy and practice of L1-based multilingual education programs, and their contribution to raising educational quality and addressing equity and inclusiveness worldwide. The second strand is qualitative, community-based research of educational programs aimed toward revitalization of minoritized, indigenous, and/or endangered languages. The third strand is empirical and theoretical research that seeks to document, contest, and reconceptualize the dynamics among dominant and non-dominant languages within and between international contexts. The authors explore points of synergy between studies, examine publication in the field from a meta-perspective, and suggest encouraging directions of future research, while highlighting the value of non-dominant languages as resources for education and life.

Abstract

Purpose

This paper aims to analyse the virtual currency regulation especially in Finland, Sweden and Norway. Different member states had a bit differently incorporated regulation of AMLD5. Finland has gone the furthest in regulation and even issuers of virtual currency are under the Finnish regulation.

Design/methodology/approach

In one hand, the study approach is legal dogmatics, but in other hand it is comparative legal research. Both approaches can be found in this paper.

Findings

The EEA is going from a more fragmented regulatory landscape based on 5th Anti-Money Laundering Directive to a more uniform regulatory approach provided by a legislative package that regulates crypto assets more broadly, coupled with an overhaul of the anti-money laundering rules, bringing them into a single European rulebook. Finland has taken a step further in this matter. Therefore, it would be reasonable for the AMLD5 scope to be expanded in this respect. It is a welcome development that the regulation will be unified and that investor protection will be better taken into account in the future as well.

Originality/value

This paper gives a picture of what kind of challenges is there in Fennoscandic in terms of money laundering regulation of virtual currencies. On the other hand, this paper brings into the discussion the rather clever solutions of Fennoscandic (especially Finland) regarding money laundering of virtual currencies.

Abstract

The demand for including enterprise in the education system, at all levels and for all pupils is now a global phenomenon. Within this context, the use of competitions and competitive learning activities is presented as a popular and effective vehicle for learning. The purpose of this chapter is to illustrate how a realist method of enquiry – which utilises theory as the unit of analysis – can shed new light on the assumed and unintended outcomes of enterprise education competitions. The case developed here is that there are inherent flaws in assuming that competitions will ‘work’ in the ways set out in policy and guidance. Some of the most prevalent stated outcomes – that competitions will motivate and reward young people, that they will enable the development of entrepreneurial skills, and that learners will be inspired by their peers – are challenged by theory from psychology and education. The issue at stake is that the expansion of enterprise education policy into primary and secondary education increases the likelihood that more learners will be sheep dipped in competitions, and competitive activities, without a clear recognition of the potential unintended effects. In this chapter, we employ a realist-informed approach to critically evaluate the theoretical basis that underpins the use of competitions and competitive learning activities in school-based enterprise education. We believe that our findings and subsequent recommendations will provide those who promote and practice the use of competitions with a richer, more sophisticated picture of the potential flaws within such activities.

Abstract

Purpose

Conventional lecture-based educational approaches alone might not be able to portray the complexity of disaster risk management practice and its real-life dynamics. One work-integrated learning practice that can give students practical work-related experiences is simulation-based learning. However, there is a limited discourse on simulation-based learning in disaster risk management education at the tertiary level. As tertiary education plays a crucial role in developing capabilities within the workforce, simulation-based learning can evoke or replicate substantial aspects of the real world in a fully interactive fashion. This paper aims to present outcomes of simulation-based learning sessions the authors designed and delivered in a disaster risk management course.

Design/methodology/approach

The authors developed a framework to illustrate simulation-based learning in a disaster risk management programme. It was then used as a guide to design and execute simulation-based learning sessions. An autoethnographic methodology was then applied to reflectively narrate the experiences and feelings during the design and execution of the simulations.

Findings

The evaluation of the simulation sessions showed that participants were able to apply their knowledge and demonstrate the skills required to make critical decisions in disaster risk reduction. The conclusion from the simulation-based learning sessions is that making simulation-based learning a part of the pedagogy of disaster risk management education enables students to gain practical experience, deliberate ethical tensions and practical dilemmas and develop the ability to work with multiple perspectives.

Originality/value

The simulated workplace experience allowed students to experience decision-making as disaster risk management professionals, allowing them to integrate theory with practice.

Abstract

Purpose

The purpose of this paper is to examine souvenir sellers as unconventional micro-entrepreneurs, focusing on non-economic motives for selling.

Design/methodology/approach

A qualitative methodology was used. Semi-structured interviews were undertaken with 20 souvenir sellers in the Romanian city of Timişoara. These were analysed using thematic analysis which identified four non-economic motives for selling souvenirs.

Findings

Souvenir selling was a matter of choice rather than economic necessity. While these sellers were entrepreneurs who were seeking to generate income, non-economic motives were also important. These included passion, hobbyism and interpersonal interactions with customers. Some sellers considered themselves as cultural intermediaries, representing place and tradition to their customers.

Research limitations/implications

In a European context, selling souvenirs can be a matter of lifestyle choice rather than economic necessity. Micro-entrepreneurs are frequently motivated by passion, hobbyism and interpersonal rewards as much as financial profit. This represents a particular form of unconventional or lifestyle entrepreneurship.

Practical implications

The encouragement of on-street souvenir sellers by urban managers can add vibrancy to a city, enhancing the experiences of local communities and visitors. This can also encourage the development of an artisan class to enhance a city’s reputation as a creative place.

Originality/value

Souvenir sellers are little researched, and this is one of few studies that has investigated this group outside Developing World contexts. This study emphasises the importance of unconventional entrepreneurship and non-economic motives for selling souvenirs in a European context.

目的

本研究将纪念品销售商这类非传统微型企业家群体作为研究对象, 重点关注其销售纪念品的非经济动机。

设计/方法论/途径

本研究主要采用定性的研究方法, 对20位罗马尼亚蒂米什瓦拉市的纪念品销售商进行了半结构化访谈。通过对访谈结果的主题分析, 本研究发现并提炼出了纪念品销售商的4种非经济动机。

发现

纪念品销售并非经济上的必然选择, 而更多地体现为一种个体的自主决策。尽管这些销售商本质上仍是追求经济回报的企业家, 其销售活动背后的非经济动机同样重要。这些动机包括对事业的激情、业余爱好, 以及与顾客之间的人际互动等。一些销售商视自身为文化传播的中介, (在销售活动中)向顾客展示地域与传统的象征。

研究限制/启示

在欧洲的语境下, 纪念品销售通常被视为一种生活方式的选择而非经济的迫切需要。微型企业家的销售行为通常受到对事业的激情、业余爱好以及人际关系的多重因素的推动, 而非单纯由经济利益驱使。这呈现出一种独特的非传统生活方式创业形态。

实际应用启示

城市管理者可以通过默许纪念品销售商在市区进行销售活动的方式为城市注入活力, 提升当地社区和游客的体验。这同时有助于培养手工艺术家阶层, 进一步增强城市作为创意之地的声誉。

研究独创性/价值

纪念品销售商的相关研究相对比较有限, 本研究在探讨这一群体时跳脱了发展中国家的框架, 同时强调了在欧洲环境下非传统创业和销售纪念品的非经济动机的重要性。

Diseño/metodología/enfoque

Se utilizó una metodología cualitativa. Se realizaron entrevistas semiestructuradas a 20 minoristas de recuerdos (souvenirs) de la ciudad rumana de Timişoara. Las entrevistas se analizaron mediante un análisis temático que permitió identificar cuatro motivos no económicos para la comercialización de recuerdos.

Objetivo

Este artículo examina a los comerciantes de souvenirs como micro emprendedores no convencionales, centrándose en los motivos no económicos para su venta.

Conclusiones

La venta de souvenirs era una cuestión de elección más que de necesidad económica. Aunque estos vendedores eran emprendedores que buscaban generar ingresos, los motivos no económicos también eran importantes. Entre ellos, la pasión, la afición y las interacciones interpersonales con los clientes. Algunos vendedores se consideraban intermediarios culturales que representaban el lugar y la tradición ante sus clientes.

Limitaciones/implicaciones de la investigación

En un contexto europeo, la venta de recuerdos puede ser una cuestión de elección de estilo de vida más que de necesidad económica. Los micro emprendedores suelen estar motivados por la pasión, la afición y las recompensas interpersonales tanto como por el beneficio económico. Esto representa una forma particular de espíritu empresarial no convencional o de estilo de vida.

Implicaciones prácticas

El fomento de los vendedores ambulantes de souvenirs por parte de los gestores urbanos puede aportar dinamismo a una ciudad, mejorando las experiencias de las comunidades locales y de los visitantes. Esto también puede fomentar el desarrollo de una clase artesanal para mejorar la reputación de una ciudad como lugar creativo.

Originalidad/valor

Los comerciantes de souvenirs están poco investigados, y éste es uno de los pocos estudios que ha investigado este grupo fuera de los contextos del mundo en desarrollo. Destaca la importancia del espíritu empresarial no convencional y de los motivos no económicos para la venta de recuerdos en un contexto europeo.
