description: Gradient-based inverse design in photonics has already achieved remarkable results in designing small-footprint, high-performance optical devices. The adjoint variable method, which allows for the efficient computation of gradients, has played a major role in this success. However, gradient-based optimization has not yet been applied to the mode-expansion methods that are the most common approach to studying periodic optical structures like photonic crystals. This is because, in such simulations, the adjoint variable method cannot be defined as explicitly as in standard finite-difference or finite-element time- or frequency-domain methods. Here, we overcome this through the use of automatic differentiation, which is a generalization of the adjoint variable method to arbitrary computational graphs. We implement the plane-wave expansion and the guided-mode expansion methods using an automatic differentiation library, and show that the gradient of any simulation output can be computed efficiently and in parallel with respect to all input parameters. We then use this implementation to optimize the dispersion of a photonic crystal waveguide, and the quality factor of an ultra-small cavity in a lithium niobate slab. This extends photonic inverse design to a whole new class of simulations, and more broadly highlights the importance that automatic differentiation could play in the future for tracking and optimizing complicated physical models.

description: The rapid advancement of artificial intelligence (AI) has led to the development of a wide array of tools which are transforming the education industry. The study investigates the adoption and use of AI tools by teachers within higher education institutions (HEIs), using the context of India. By employing an extended Unified Theory of Acceptance and Use of Technology (UTAUT) model, the study empirically examines the influence of two technological attributes (i.e. performance expectancy and effort expectancy), two contextual factors (i.e. social influence and facilitating conditions) and two personal characteristics (i.e. personal innovativeness and computer self-efficacy) on teachers’ behavioural intention to use AI tools for research work. The primary data were collected from 331 teachers working with HEIs in the Delhi-National Capital Region (NCR) of India. PLS-SEM technique was used to analyze the data. The findings indicate that teachers’ intention to adopt AI tools for research work is positively influenced by performance expectancy, effort expectancy, social influence, computer self-efficacy and personal innovativeness. Further, their actual use of AI tools is influenced by their behavioural intention and facilitating conditions. The study provides further verification of the effectiveness of the UTAUT framework in the context of using emerging technologies in the education sector. Findings from this study provide beneficial insights for HEIs and developers of AI tools.

description: Immersive technologies such as Virtual, Augmented and Mixed Reality are among the most talked up terms in todays technology journalism. The mostly utopian promises forecast a major platform shift that might revolutionize the way in which we interact with technology. The large tech companies invest vast amounts of money in the technologies and see it as a placeholder for a future in which immersive technologies have developed far enough to have the disruptive potential to become the next big computing platform. Despite big promises, sales figures of Virtual Reality headsets and Augmented Reality glasses remain underwhelming due to technical shortcomings and the fact that feedback from consumers remains reserved or even indifferent. Since the 1980s, Virtual Reality has persistently returned, each time with idealistic promises and each time it has ultimately failed. The paper asks the question whether the current boom is sustainable and will ultimately lead to a widespread adoption of the technologies. Several opinion leaders in the industry were interviewed and asked about their past experience with Augmented, Virtual and Mixed Reality. Conclusions are drawn about the potential in key industries such as Automotive, Retail / Consumer, Healthcare / Medicine, Technology / Media / Telecom, Industrial Products, Hospitality / Leisure and Education / Training in the context of technology adoption and technological competence leveraging.
Adult learning in new social movements : a conceptual inquiry into the voluntary simplicity movement
Creators: name: Crisfield, Erin Marie
Publisher: name: University of British Columbia

description: The purpose of this project is to explore adult learning in new social movements through the case of the voluntary simplicity movement. The goals of the project are: to add to the research on adult learning within new social movements, to contribute to the discussions of transformative learning and sociocultural learning, and to influence the practice of educators who are working within new social movements. 1 approach the research with both theoretical and practical questions and goals, identifying myself as a scholarly practitioner by reflecting on both theory and practice with the intent of influencing the practice of those involved in related work as well as contributing to knowledge construction. In this research, I draw on the literature of a particular movement and on various streams of theoretical literature in order to generate new knowledge about adult learning in new social movements. Using elements of the Precede-Proceed model (Green & Kreuter, 1999), I show the predisposing, enabling, and reinforcing factors of adult learning in the voluntary simplicity movement. These factors present a picture of what comprises the various aspects of adult learning in this movement. Further exploration of the factors in light of Kilgore’s (1999) conception of collective learning leads to an understanding that identity, agency, and solidarity are the three main components of adult learning in the voluntary simplicity movement. Both transformative learning and sociocultural learning theories illuminate aspects of the data in ways that contribute to and reinforce my analysis that learning in the movement revolves around identity, agency, and solidarity. Implications for both theory and practice are explored with suggestions for hrther research.

description: This article demonstrates the validity and reliability of an instrument to evaluate the level of digital competence of Higher Education (HE) teachers in the use of digital resources in research work. The initial instrument was made up of a total of 22 items classified into four dimensions: (DIM. 1. Digital skills to search for information, manage it, analyze it and communicate results; DIM. 2. Digital ethics in digital research; DIM. 3. Digital flow in research work; DIM. 4. Anxiety towards the use of ICT resources for research). The instrument was applied to a final sample of 1709 teachers from different higher education institutions in Spain, from an initial sample of 1740. Reliability was measured using Cronbach’s Alpha and composite reliability. To check the validity of the instrument, the validity of understanding and exploration of dimensionality was analyzed using Exploratory Factor Analysis (EFA), and the instrument was adjusted for the different models using Confirmatory Factor Analysis (CFA). IBM SPSS V.24 software was used for the AFE and AMOS V.24 software was used for the AFC. The result of the reliability analyzes were adequate and, in relation to construct validity, the results found a good fit of the model, both in internal validity and factorial invariance. The final version of the instrument consists of 12 items.

description: The Internet of Things (IoT) presents a unique flexibility that facilitates higher productivity and rapid advancement in the educational sector, and more specifically in educational assessment. However, the huge cybersecurity issues associated with cyberspace pose a challenge for the IOT. The present study investigated the influence of the Internet of Things Cybersecurity (IoTCS) on educational assessment practices in university learning spaces. The researchers adopted a correlation research design involving a multistage sampling procedure with 297 lecturers as participants drawn from six universities in South-East Nigeria, who shared their opinions on the influence of IoTCS on assessment practices. The Internet of Things Cybersecurity Questionnaire (IoTCSQ) and Assessment Practices Scale (APS) were two instruments used for data collection and they were validated in line with the purpose of the study by three experts. The Cronbach Alpha reliability indices of the two instruments were 0.82, and 0.89 respectively. The result showed a significantly moderate positive relationship between the adoption of IoTCS and the effectiveness of assessment practices in university learning spaces, among others. The study concluded that the incorporation of IoTCS significantly influences assessment practices in university learning spaces, and recommended among others that school administrators should consider investing in IoT cybersecurity for the safety, fairness and reliability of assessment data.

description: Digital Transformation" is shapeshifting the business world but there are a couple of questions, not the least, what the term exactly stands for and what it implies for companies. How can SMEs, representing almost 49% of revenues and 44% of gross value added in Austria, benefit from it? While large companies have the resources to invest, and small startups are positioned at the heart of digital transformation, SMEs seem to lack both: They have neither the financial and personal resources, nor the agility, to assess the chances and the necessities of digitalization. In this thesis, a common framework is established for Small and Medium Sized Enterprises to provide them with a way to strategically deal with the challenges of digitalization. The digital strategy framework presented is particularly suitable for SMEs. It addresses specifically the question of what a process needs to include to enable the implementation of the strategy afterwards. The framework describes the three-step process (digital reality, digital ambition, digital roadmap) along six relevant dimensions of digitalization. For each step, the relevant actions and results are described. The strategy framework also lists the relevant output of the process. It stresses the importance of easily understandable, visual aids (“digital roadmap”) to communicate the strategy (vision, goal, projects). The process and the related elements, as well as the relevant dimensions, where extracted and synthesized from existing frameworks and verified in expert interviews. The expert interviews give insights to questions not answered from the existing frameworks, in particular addressing the results of the strategy process in the form of defined projects and timelines. The digital strategy framework was then presented to four SMEs to validate its usefulness. The framework is of high practical value for any company that starts a digital transformation or needs to coordinate its digitalization initiatives. It is helpful for both SMEs and consultants as a guide in the strategy development.

description: Este trabajo tiene como objetivo estudiar las ganaderias de lidia a nivel nacional, dada su trascendencia social, zootecnica y economica. Para ello se han realizado encuestas a 177 ganaderos analizando los factores comunes que permitan caracterizar las ganaderias y explotaciones, asi como conocer su problematica y necesidades en un momento delicado para el sector ganadero en general, y las explotaciones de raza bovina de lidia en particular. Los resultados del trabajo muestran que las ganaderias de lidia espanolas tendrian una extension media de 536 ha (la mayoria en propiedad) y tienen 361 animales (habitualmente acompanados de ganado equino, vacuno de carne y porcino iberico), cuyo principal destino es la venta para festejos populares y corridas de toros. Las explotaciones cuentan con asistencia veterinaria fija y una media de tres trabajadores por explotacion (mano de obra cualificada, familiar o asalariada). This work aims to study the herds of Lidia bulls in Spain, given their social, economic and animal husbandry relevance. To achieve this, 177 surveys to farmers were carried out, analyzing the common factors to characterize the farms, and to know their problems and needs in the current socio economic circumstances, which are especially troublesome for the livestock vector in general and for Lidia bulls' farms in particular. The results of this paper show that Lidia farms have on average an extension of 536 ha and have 361 Lidia breed animals (together with equine, beef cattle and Iberian pigs), usually sold for popular bull festivals and bullfights. Farms have regular veterinary assistance and an average of three workers per far, (familiar or waged qualified labor).

description: El presente trabajo se realizo con el fin de estudiar el sector ganadero de lidia espanol desde un punto de vista social y economico, medinate encuestas a ganaderos de lidia. Los resultados del trabajo permiten definir al ganadero "tipo", como un varon de 48 anos, con 2 hijos, que habitualmente no disfruta de vacaciones y que dedica, de media 8 horas, 6 dias a la semana, a su trabajo. Mas de la mitad de las ganaderias venden erales y utreros, un tercio anojos y casi un 50% toros. Los principales problemas a los que se enfrenta el sector son la falta de union, el aumento progresivo de los costes, la reduccion en el numero de festejos y la escasez de mano de obra especializada hacen que los ganaderos, pese a identificarse profundamente con su actividad )que tiene caracter vocacional, tradicional y familiar), expresan su incertidumbre frente al futuro. This work was preformed in order to study the Spanish Lidia livestock sector from social and economical points of view. The results of this paper allows defining the concept of "farmer type" as a 48 years-old man, with 2 children, who does not usually enjoy vacation and works, on average, 8 hours a day, 6 days a week. More than one half of the farms sell 'erales' and 'uteros', one third of the farms sell 'anojos' and almost 50% sell 'toros'. The main problems that the sector is facing are the lack of farmers' union, the progressive increase in costs, the reduction in the number of celebrations and shortage of skilled work force. Thus, farmers, despite being deeply identified with their activity (which has a traditional, familiar and vocational nature), expressed their uncertainty about the future.

description: Time-resolved optical measurements of electron spin dynamics in modulation doped InGaAs quantum wells are used to explore electron spin coherence times and spin precession frequencies in a regime where an out of plane magnetic field quantizes the states of a two-dimensional electron gas into Landau levels. Oscillatory features in the transverse spin coherence time and effective g-factor as a function of applied magnetic field exhibit a correspondence with Shubnikov-de Haas oscillations, illustrating a coupling between spin and orbital eigenstates. We present a theoretical model in which inhomogeneous dephasing due to the population of different Landau levels limits the spin coherence time and captures the essential experimental results.

description: The main objective of this Masters thesis is to produce a financing guideline for entrepreneurs on how to use traditional and alternative sources of capital, without increasing the personal financial risk of the founders. Many traditional sources of capital, such as character loans, will require the full personal liability of a founder. As a consequence, the private savings of entrepreneurs are at permanent risk while creating new ventures. This might lead to situations where founders are not able to take optimal decisions for the start-ups or it might even prevent individuals from becoming entrepreneurs in the first place. As a matter of fact, the author has chosen literature from personal financial planning as well as from investment theory to focus on the long-term objectives of entrepreneurs, instead of the interests of capital lenders and investors. In addition, traditional and alternative sources of capital for start-ups have been qualified based on personal liability in the different financing stages of a new business. This should allow entrepreneurs to reduce personal risk and to focus on building successful business ventures.

description: Due to digitalization, automation and globalization todays workers skills will quickly become obsolete. In order to equip the workforce of the future, schools need to quickly adapt their curricula to the new challenges and start teaching competencies relevant for the future. Implementing these so-called ‘21st century skills in schools means allowing and facilitating change and innovation. Technology can act as a catalyst for change, but the focus must shift from the technologies to the pedagogies of use to create a real benefit in learning and teaching. The aim of this master thesis is to illustrate how educational technology is used correctly to achieve added value. We are exploring how Austrias schools can better exploit the potential of educational technologies, and which challenges exist, both in general and specifically in the Austrian education system that seems to inhibit this development. Our research process was based on a mixed methods approach. A standardized questionnaire survey sent out to 100 primary schools in Austria and five expert interviews were performed. Based on our findings we developed the ‘House of Future Education, a framework that illustrates what is needed for innovating the Austrian school system. In addition, a business plan for a multi-sided platform business, the Ah! Aha! Haha! Lab was developed, which aims to prepare all children for an ever-changing, technologically driven world by teaching 21st century skills with 21st century technologies. It needs teachers who are not afraid of technology, but curious to experiment. It needs Start-Ups that act impact-driven and are eager to develop real solutions to existing problems. Moreover, it needs systems that support and facilitate innovation and governments, that are brave enough, to rethink old and perhaps outdated structures. Although educational technology can only support 21st century teaching and learning, they must take on a central role on our journey to innovate and modernize the educational system. This requires patience, because fundamental changes of whole systems take time. Nevertheless, for this to happen, the discussion, the critical questioning and the constant debate on the subject must be kept alive.

description: This study comprehensively compares and analyzes eight representative global frameworks for teacher Information and Communication Technology (ICT) competencies, each reflecting regional educational priorities and philosophies. The research aims to transcend geographical boundaries by identifying consensus on key areas of teacher ICT competencies and exploring unique characteristics of each framework within specific educational contexts and challenges. The findings indicate that despite diversity, global teacher ICT competencies represent an integration of knowledge, skills, and values, particularly in digital society building, digital career development, digital communication and collaboration, digital assessment, digital teaching and learning, and development of students’ digital competencies. The study further highlights varying emphasizes among frameworks in core areas and competencies, accompanied by varying levels of implementation support. Ultimately, the paper provides recommendations to assist educators, policymakers, and digital leaders in understanding global standards for teacher ICT competencies, developing effective and inclusive frameworks, and exploring best practices for advancing teacher ICT competencies.

The limits of the possible : the theory and practice of worker-centred literacy in the context of global capitalism
Creators: name: Evans, Sarah
Publisher: name: University of British Columbia
Year: 2010

description: The goal of this study is to outline the limits and possibilities for change that worker-centred literacy offers in the context of global capitalism. To this end, this study examines contemporary Canadian discourses of 'workplace literacy' in the new knowledge-based economy and, in particular, explores how the emerging discourse of 'worker-centred literacy' replicates and resists the current emphasis on learning for work. Generally, 'workplace literacy' refers to adult literacy or basic skills programs that take place in work sites, sometimes on work time and usually with skill-based curricula. 'Worker-centred literacy' refers to certain approaches developed or championed by trade unions for their members in unionized worksites. Union organizations do not all endorse a worker-centred approach. There is currently a range of notions about the goals of literacy programming at work, from the development of a more productive, flexible and responsive workforce, to the personal and/or political empowerment of learners/workers. In this study, the 'talk' about these literacies will be analyzed in order to explicate the conflicting sets of interests and political perspectives they represent and the tensions between their competing theories of knowledge making. The main focus of this study will be an exploration o f worker-centred literacy as an oppositional, counter-hegemonic discourse. First, this study will examine why and how labour literacy activists articulate an agenda for literacy that is oppositional to the dominant discourse, with its focus on learning that is geared towards work, and on the skills deficits of Canadian workers. This study will also examine the tensions inherent within the worker-centred approach itself, and the ways in which this project both reproduces and reforms the dominant discourse. Finally, this study will examine worker-centred literacy and the work of labour literacy activists in relation to the evolving role of the labour movement in contemporary Canadian society. This study will conclude that labour literacy activists posit worker-centred literacy as a catalyst for changing the relationship between unions and their membership, and, thereby, for expanding and modernizing the role of unions in response to the pressures of global capitalism.

description: Optical Coherence Tomography (OCT) is a non-invasive depth resolved optical imaging modality, that enables high resolution, cross-sectional imaging in biological tissues and materials at clinically relevant depths. Though OCT offers high resolution imaging, the best ultra-high-resolution OCT systems are limited to imaging structural changes with a resolution of one micron on a single B-scan within very limited depth. Nanosensitive OCT (nsOCT) is a recently developed technique that is capable of providing enhanced sensitivity of OCT to structural changes. Improving the sensitivity of OCT to detect structural changes at the nanoscale level, to a depth typical for conventional OCT, could potentially improve the diagnostic capability of OCT in medical applications. In this paper, we demonstrate the capability of nsOCT to detect structural changes deep in the rat cornea following superficial corneal injury.

Examining factors influencing the emergence of a knowledge society: an explorative study
Creators: name: ZNAGUI, Zineb
Publisher: name: Journal of e-Learning and Knowledge Society
Year: 2024

description: This article addresses the contextual ambiguity prevalent in the literature surrounding the conceptualizations of a knowledge society. By identifying and clarifying these conceptual challenges, the research aims to provide a solid foundation for understanding the factors influencing the emergence of a knowledge society. The objectives include presenting a clear and comprehensive representation of the multifaceted elements that contribute to this societal transition. Methodologically, a quantitative approach is employed using a regression analysis. The originality of this research lies in its endeavor to develop new perspectives and insights into the catalysts behind the emergence of a knowledge society.

description: El trabajo infantil rural es uno de los princiaples flagelos de la sociodad actual, es clasificado por la OIT como una de las peores formas de trabajo infantil. En Mexico a pesar de que su practica esta prohibida, cada dia, ninos/as y adolescentes se suman al mercado de mano de obra, en particular, la agricola. Ante esta realidad, el presente estudio tiene como objetivo valorar el trabajo infantil rural y sus impliacaciones en el altiplano poblano. Se concluye que el trabajo infantil es un fenomeno que esta en franco crecimiento, su configuracion esta asociada a la violencia estructural de las politicas de ajuste estructural instrumentadas en las ultimas tres decades donde los territorios rurales se reconfiguraron para adaptarse a la nuevas condiciones socioeconomicas. Rural child labour is one of the main scourges of modern society, it is classified by the ILO as one of the worst forms of child labor. In Mexico even though their practice is prohibited, every day, boys/girls and adolescents are added to the labor market, in particular agriculture. Given this reality, the present study aims to assess the rural child labor and its implications in the highlands poblano. We conclude that child labor is a phenomenon that is growing strongly, its configuration is associated with the structural violence of structural adjustment policies implemented in the last three decades where rural areas were reconfigured to adapt to the new economic conditions.

Mapping from current densities to vector potentials in time-dependent current-density functional theory

description: We show that the time-dependent particle density $n(\vec r,t)$ and the current density ${\vec j}(\vec r,t)$ of a many-particle system that evolves under the action of external scalar and vector potentials $V(\vec r,t)$ and $\vec A(\vec r,t)$ and is initially in the quantum state $|ψ(0)>$, can always be reproduced (under mild assumptions) in another many-particle system, with different two-particle interaction, subjected to external potentials $V'(\vec r,t)$ and $\vec A'(\vec r,t)$, starting from an initial state $|ψ' (0)>$, which yields the same density and current as $|ψ(0)>$. Given the initial state of this other many-particle system, the potentials $V'(\vec r,t)$ and $\vec A'(\vec r,t)$ are uniquely determined up to gauge transformations that do not alter the initial state. As a special case, we obtain a new and simpler proof of the Runge-Gross theorem for time-dependent current density functional theory. This theorem provides a formal basis for the application of time-dependent current density functional theory to transport problems.

description: Accurate nuclear matrix elements (NMEs) for neutrinoless double beta decays of candidate nuclei are important for the design and interpretation of future experiments. Significant progress has been made in the modeling of these NMEs from first principles. The NME for 48Ca shows a good agreement among three different ab initio calculations starting from the same nuclear interaction constructed within the chiral EFT and the same decay operator. These studies open the door to ab initio calculations of the matrix elements for the decay of heavier nuclei such as 76Ge, 130Te, and 136Xe. The ultimate goal is the computation of NMEs in many-body calculations with controllable approximations, using nuclear interactions and weak transition operators derived consistently from chiral EFT. We are expecting more progress towards this goal in the near future.

description: Globalization and trade liberalization have created both challenges and opportunities for small island states like Dominica. Post 1995, the removal of preferential access to EU markets for Dominica’s banana resulted in increased competition and subsequently loss of market share to larger efficient producers. However, the liberalization of trade also presented opportunities for the marketing of nontraditional crops. Hence, Dominica embarked on diversification programmes establishing among others a hot pepper industry as a replacement to bananas to supply fresh hot pepper to local, regional and extra regional markets. While the industry may be attractive in terms of prices and volume demand, Dominica has been challenged to meet current market demands, and at competitive prices. This study assessed the competitiveness of Dominica’s hot pepper industry in a major extra regional market (Miami Wholesale Market) using the Export Competitiveness Coefficient Model (ECC). Value chain analysis was used to analyze the segments of the supply chain’s contribution to production, processing and marketing. The study found that Dominica’s hot pepper industry was not price competitive at current levels of productivity (4lbs per plant) and the average market price. However, at higher levels of productivity (> 4lbs per plant), Dominica’s hot pepper industry would be price competitive at all market price levels. In addition, the study found that productivity of hot peppers in Dominica using irrigation was 50% higher and profitability 25% higher than rainfed technology. Finally, the study found that lack of information sharing and communications among key stakeholders were major constraints along the supply chain.

description: A multispecies approach may reveal the factors influencing the genetic differentiation of coexisting species along a wide geographic area. Our aim was to compare the genetic differentiation of mangrove crabs coexisting along the western Atlantic in order to verify if there are common barriers, using two mitochondrial DNA markers to quantify genetic differentiation, variance and diversity. In addition, we included a mismatch distribution to check demographic history. Our data revealed that species with similar pelagic larval duration had either high genetic differentiation or the absence of genetic structure. These results can be explained by factors that contribute to genetic differentiation, such as the presence of large estuarine areas (acting as barriers), ocean currents, and larval behaviour. Also, historical events that promoted the isolation of some areas in the past, such as glacial cycles during the Pleistocene, could have caused the observed high levels of genetic divergence in some species.
