24698 Solar Power Forecasting for the Bidding Zones of the Italian Electricity Market with an Analog Ensemble Approach
Authors: Elena Collino, Dario A. Ronzio, Goffredo Decimi, Maurizio Riva
Abstract:
The rapid increase of renewable energy in Italy is led by wind and solar installations. The 2017 Italian energy strategy foresees a further development of these sustainable technologies, especially solar. This fact has resulted in new opportunities, challenges, and different problems to deal with. The growth of renewables allows to meet the European requirements regarding energy and environmental policy, but these types of sources are difficult to manage because they are intermittent and non-programmable. Operationally, these characteristics can lead to instability on the voltage profile and increasing uncertainty on energy reserve scheduling. The increasing renewable production must be considered with more and more attention especially by the Transmission System Operator (TSO). The TSO, in fact, every day provides orders on energy dispatch, once the market outcome has been determined, on extended areas, defined mainly on the basis of power transmission limitations. In Italy, six market zone are defined: Northern-Italy, Central-Northern Italy, Central-Southern Italy, Southern Italy, Sardinia, and Sicily. An accurate hourly renewable power forecasting for the day-ahead on these extended areas brings an improvement both in terms of dispatching and reserve management. In this study, an operational forecasting tool of the hourly solar output for the six Italian market zones is presented, and the performance is analysed. The implementation is carried out by means of a numerical weather prediction model, coupled with a statistical post-processing in order to derive the power forecast on the basis of the meteorological projection. The weather forecast is obtained from the limited area model RAMS on the Italian territory, initialized with IFS-ECMWF boundary conditions. The post-processing calculates the solar power production with the Analog Ensemble technique (AN). This statistical approach forecasts the production using a probability distribution of the measured production registered in the past when the weather scenario looked very similar to the forecasted one. The similarity is evaluated for the components of the solar radiation: global (GHI), diffuse (DIF) and direct normal (DNI) irradiation, together with the corresponding azimuth and zenith solar angles. These are, in fact, the main factors that affect the solar production. Considering that the AN performance is strictly related to the length and quality of the historical data a training period of more than one year has been used. The training set is made by historical Numerical Weather Prediction (NWP) forecasts at 12 UTC for the GHI, DIF and DNI variables over the Italian territory together with corresponding hourly measured production for each of the six zones. The AN technique makes it possible to estimate the aggregate solar production in the area, without information about the technologic characteristics of the all solar parks present in each area. Besides, this information is often only partially available. Every day, the hourly solar power forecast for the six Italian market zones is made publicly available through a website.Keywords: analog ensemble, electricity market, PV forecast, solar energy

Authors: Danilo López, Edwin Rivas, Leyla López
Abstract:
This paper presents the development of an algorithm that predicts the arrival of a secondary user (SU) to a base station (BS) in a cognitive network based on infrastructure, requesting a Best Effort (BE) or Real Time (RT) type of service with a determined bandwidth (BW) implementing neural networks. The algorithm dynamically uses a neural network construction technique using the geometric pyramid topology and trains a Multilayer Perceptron Neural Networks (MLPNN) based on the historical arrival of an SU to estimate future applications. This will allow efficiently managing the information in the BS, since it precedes the arrival of the SUs in the stage of selection of the best channel in CRN. As a result, the software application determines the probability of arrival at a future time point and calculates the performance metrics to measure the effectiveness of the predictions made.Keywords: cognitive radio, base station, best effort, MLPNN, prediction, real time

Authors: Richard McGregor, Carmen Reaiche, Stephen Boyle
Abstract:
Cyber threats are a relatively recent phenomenon and offer cyber insurers a dynamic and intelligent peril. As individuals en mass become increasingly digitally dependent, Personal Cyber Insurance (PCI) offers an attractive option to mitigate cyber risk at a personal level. This abstract proposes a literature review that conceptualises a framework for siting Personal Cyber Insurance (PCI) within the context of cyberspace. The lack of empirical research within this domain demonstrates an immediate need to define the scope of PCI to allow cyber insurers to understand personal cyber risk threats and vectors, customer awareness, capabilities, and their associated needs. Additionally, this will allow cyber insurers to conceptualise appropriate frameworks allowing effective management and distribution of PCI products and services within a landscape often in-congruent with risk attributes commonly associated with traditional personal line insurance products. Cyberspace has provided significant improvement to the quality of social connectivity and productivity during past decades and allowed enormous capability uplift of information sharing and communication between people and communities. Conversely, personal digital dependency furnish ample opportunities for adverse cyber events such as data breaches and cyber-attacksthus introducing a continuous and insidious threat of omnipresent cyber risk–particularly since the advent of the COVID-19 pandemic and wide-spread adoption of ‘work-from-home’ practices. Recognition of escalating inter-dependencies, vulnerabilities and inadequate personal cyber behaviours have prompted efforts by businesses and individuals alike to investigate strategies and tactics to mitigate cyber risk – of which cyber insurance is a viable, cost-effective option. It is argued that, ceteris parabus, the nature of cyberspace intrinsically provides characteristic peculiarities that pose significant and bespoke challenges to cyber insurers, often in-congruent with risk attributes commonly associated with traditional personal line insurance products. These challenges include (inter alia) a paucity of historical claim/loss data for underwriting and pricing purposes, interdependencies of cyber architecture promoting high correlation of cyber risk, difficulties in evaluating cyber risk, intangibility of risk assets (such as data, reputation), lack of standardisation across the industry, high and undetermined tail risks, and moral hazard among others. This study proposes a thematic overview of the literature deemed necessary to conceptualise the challenges to issuing personal cyber coverage. There is an evident absence of empirical research appertaining to PCI and the design of operational business models for this business domain, especially qualitative initiatives that (1) attempt to define the scope of the peril, (2) secure an understanding of the needs of both cyber insurer and customer, and (3) to identify elements pivotal to effective management and profitable distribution of PCI - leading to an argument proposed by the author that postulates that the traditional general insurance customer journey and business model are ill-suited for the lineaments of cyberspace. The findings of the review confirm significant gaps in contemporary research within the domain of personal cyber insurance.Keywords: cyberspace, personal cyber risk, personal cyber insurance, customer journey, business model

Authors: AbdulHameed Badmas Yusuf
Abstract:
Islamophobia is unfounded fear of Islam and, more accurately, of his adherents. This phenomenon has found a fertile terrain in Nigeria given her status as a multireligious society where Muslims and Christians co-exist. Over the years, Islamophobia has taken constitutional, diplomatic, educational, financial, and political dimensions in the country. Any move by Muslims to adhere to their religious dictates, within the constitutional framework, is misconstrued by Christians - their religious counterparts- as a systematic way of Islamizing the country. Against this backdrop, this paper casts a look at Islamophobia from the five dimensions mentioned above. It shall identify possible causes of Islamophobia and proffer solutions accordingly. Available resources as well as events in the recent past reveal that Islamophobia is not unconnected with orientalism and terrorism, which are informed by prejudice and ignorance respectively. As such, the paper suggests adequate knowledge and tolerance as inevitable tools to curtail the menace of Islamophobia. This will go a long way in enhancing mutual tolerance and peaceful co-existence among the adherents of Christianity, Islam, and other religions in Nigeria. Both historical and analytical methods are used in this paper.Keywords: islamophobia, islam, Nigeria, orientalism, terrorism

Authors: Alex Lundy
Abstract:
As the suburban landscape has evolved over time, it has been slowly stripped down to the absolute bare essentials of housing. This has resulted in the loss of core elements of the built environment which previously supported community no longer being present in most neighborhoods. As a result, this work will explore how current and past designers have successfully introduced these concepts in similar settings, in an effort to re-implement them into the contemporary subdivision. Ultimately, this will result in a reimagining suburban design through elements like identity, adaptability, place, and social spaces to improve community interaction and cohesion. Overall, this thesis asserts that contemporary subdivisions don’t support the growing need for community in daily life and should be improved through the implementation of historical neighborhood design and select modern urban concepts to better suit living needs.Keywords: suburbia, community, social connection, identity, adaptability, neighborhood, place, unity, leasure, social ties, third place, learning from history

Authors: Mustafina-Bredikhina Diana, Kuznetsova Olga
Abstract:
Corruption as a social phenomenon is obviously a serious barrier to the development of a prosperous society and the economic development of the country as a whole. It is extremely important to analyze the influence of culture on the level of corruption in different countries and assesses the influence of culture, religion, and mentality on corrupt behavior and their perception in society. Corruption should be considered in relation to the public consciousness, which is formed in certain socio-historical conditions and cultural traditions. Often, society, formally condemning corruption, reproduces obvious corrupt behavior at the personal level of its individual members. Based on a brief analysis of the major corruption scandals and the corruption counting system of countries, the authors conclude that culture, mentality, and religion, while playing an important role in the formation of public consciousness of the concept of "corrupt behavior" are not decisive. It is more important to build a dialogue between the authorities and society, creating a uniform rejection of corrupt behavior.Keywords: corruption, culture, corrupt behavior, perception of corruption, religion

Authors: Baohua Yu
Abstract:
In line with wider tends in the expansion of international student mobility, the number of international higher degree research students has grown at a significant rate in recent years. In particular, Australia has become a hub for attracting international higher degree research students from around the world. However, research has identified that international higher degree research students often encounter a wide range of academic and socio-cultural challenges in adapting to their new environment. Moreover, this can have a significant bearing on their levels of satisfaction with their studies. This paper outlines the findings of a mixed method study exploring the experiences and perceptions of international higher degree research students in Australia. Findings revealed that IRHD students’ overall and academic satisfaction in Australia were highly related to each other, and they were strongly influenced by their learning and research, moderately influenced by co-national support and intercultural contact ability. Socio-cultural satisfaction seemed to belong to a different domain from academic satisfaction because it was explained by a different set of variables such as living and adaptation and intercultural contact ability. In addition, the most important issues in terms of satisfaction were not directly related to academic studies. Instead, factors such as integration into the community, interacting with other students, relationships with supervisors, and the provision of adequate desk space were often given the greatest weight. Implications for how university policy can better support international doctoral students are discussed.Keywords: international higher degree research students, academic adaptation, socio-cultural adaptation, student satisfaction

Authors: Salomé Elizabeth Scholtz
Abstract:
Reviewers are the gatekeepers of knowledge dissemination and promote the scientific validity of the research. However, the literature indicates that authors often receive questionable feedback on qualitative manuscripts. Thus, this qualitative descriptive study sought to explore the qualitative knowledge and experiences of reviewers of psychology journals. A purposive and snowball sample (n=27) of psychology journal reviewers completed an online questionnaire, and data were analyzed using thematic analysis. Reviewers felt their postgraduate education, reading, and the process of reviewing qualitative articles equipped them to review qualitative manuscripts. Less than half of the reviewer’s published articles were qualitative and male reviewers published more than females. Despite not expecting authors to have the same level of research skills, reviewers still experienced authors as unskilled and biased, creating difficulty in accepting and reviewing qualitative articles. The applicability of the qualitative method and recommendations in preparing qualitative manuscripts for reviewing are reported.Keywords: journal reviewers, psychology, qualitative research, research method, research skills

Authors: Vanda Božić, Željko Nikač
Abstract:
The wars and armed conflicts have often resulted in violations of international humanitarian law, and often commit the most serious international crimes such as war crimes, crimes against humanity, aggression and genocide. However, only in the XX century the rule was articulated idea of establishing a body of international criminal justice in order to prosecute these crimes and their perpetrators. The first steps in this field have been made by establishing the International military tribunals for war crimes at Nuremberg and Tokyo, and the formation of ad hoc tribunals for the former Yugoslavia and Rwanda. In the end, The International Criminal Court was established in Rome in 1998 with the aim of justice and in order to give satisfaction the victims of crimes and their families. The aim of the paper was to provide a historical and comparative analysis of the institutions of international criminal justice based on which these institutions de lege lata fulfilled the goals of individual criminal responsibility and justice. Furthermore, the authors suggest de lege ferenda that the Permanent International Criminal Tribunal, in addition to the prospective case, also takes over the current ICTY and ICTR cases.Keywords: international crimes, international criminal justice, prosecution of crimes, ad hoc tribunal, the international criminal court

Authors: Giriraj Achari, Malay Bhattacharyya
Abstract:
In this paper, the effectiveness of Copula Markov Switching Multifractal (MSM) models at forecasting Value-at-Risk of a two-stock portfolio is studied. The innovations are allowed to be drawn from distributions that can capture skewness and leptokurtosis, which are well documented empirical characteristics observed in financial returns. The candidate distributions considered for this purpose are Johnson-SU, Pearson Type-IV and α-Stable distributions. The two univariate marginal distributions are combined using the Student-t copula. The estimation of all parameters is performed by Maximum Likelihood Estimation. Finally, the models are compared in terms of accurate Value-at-Risk (VaR) forecasts using tests of unconditional coverage and independence. It is found that Copula-MSM-models with leptokurtic innovation distributions perform slightly better than Copula-MSM model with Normal innovations. Copula-MSM models, in general, produce better VaR forecasts as compared to traditional methods like Historical Simulation method, Variance-Covariance approach and Copula-Generalized Autoregressive Conditional Heteroscedasticity (Copula-GARCH) models.Keywords: Copula, Markov Switching, multifractal, value-at-risk

Authors: Donato Maniello, Alessandra Cirafici, Valeria Amoretti
Abstract:
This paper aims to present a new method that consists in the use of video mapping techniques – that is a particular form of augmented reality, which could produce new tools - different from the ones that are actually in use - for an interactive Museum experience. With the words 'augmented reality', we mean the addition of more information than what the visitor would normally perceive; this information is mediated by the use of computer and projector. The proposed application involves the creation of a documentary that depicts and explains the history of the artifact and illustrates its features; this must be projected on the surface of the faithful copy of the freeze (obtained in full-scale with a 3D printer). This mode of operation uses different techniques that allow passing from the creation of the model to the creation of contents through an accurate historical and artistic analysis, and finally to the warping phase, that will permit to overlap real and virtual models. The ultimate step, that is still being studied, includes the creation of interactive contents that would be activated by visitors through appropriate motion sensors.Keywords: augmented reality, multimedia, parthenon frieze, video mapping
Procedia PDF Downloads 38724685 Teacher Training for Bilingual Education of Deaf Students in Brazil
Authors: Mara Aparecida De Castilho Lopes. Maria Eliza Mattosinho Bernardes
Abstract:
The education of deaf individuals in Brazil is grounded in the bilingual approach, which presupposes Brazilian Sign Language (Libras) as the first language for these students. In this perspective, Portuguese should be taught as a second language in its written form, ensuring that deaf students also have access to various academic subjects in sign language. Brazilian legislation (Federal Decree No. 5626 of 2005) mandates the teaching of Brazilian Sign Language in university teacher training programs, but there is no pre-established minimum workload. As a result, there is a significant disparity in the teaching and quality of teacher education across the Brazilian territory. Added to this fact is the general lack of awareness within society regarding the linguistic status of Libras, leading to a shortage of competent teachers for its use and instruction, particularly in higher education. Recently, Federal Law No. 14191 of 2021 established bilingual education for the deaf as a mode of instruction, indicating the need for adjustments in teacher training within higher education teacher preparation programs. Given this context, the objective of the present study was to analyze the teaching proposals for Brazilian Sign Language for students in teacher training programs at public universities in Brazil, presenting alternatives to overcome the current models and academic pathways of teaching and learning. In addition to analyzing Brazilian teaching models, an analysis of a continuing education model for teachers in a French institution was also conducted - considering the historical Franco-Brazilian path of deaf education in Brazil. The analysis of the current teacher training model for deaf education in Brazil revealed that initial exposure to sign language and its linguistic structure is not sufficient to provide future teachers with opportunities to reflect on bilingual teaching methods and practices, as seen in other definitions of bilingualism - bilingual education for proficient listeners in two oral languages. As a result, a training proposal was developed for an experimental interdisciplinary course, integrating the curriculum of an initial and continuing teacher training program alongside the Alfredo Bossi Chair at the University of São Paulo. This proposal is structured into three disciplines, which constitute consecutive moments in teacher education: Fundamental Aspects of Brazilian Sign Language, Bilingual Teaching Methodology, and Teaching Investigation Project - interdisciplinary engagement in the field of deafness. The last offered discipline represents an interdisciplinary supervised internship proposal, considering the multi-professional context that constitutes deaf education within a bilingual approach. In interdisciplinary work within the field of deafness, dialogue between teachers and other professionals who work with deaf students from different perspectives - teachers, speech therapists, and sign language interpreters - is frequently necessary. Through alternative avenues, these actions aim to direct the linguistic development of deaf students within their learning processes. Based on the innovative curriculum proposal described here, the intention is to contribute to the enhancement of teacher education in Brazil, with the goal of ensuring bilingual education for deaf students.Keywords: bilingual education, teacher training, historical-cultural approach, interdisciplinary education, inclusive education

Authors: Stephen Barnes, Ian Mills, Frances Cleary
Abstract:
Augmented and virtual reality-based applications offer many benefits for the heritage and tourism sector. This technology provides a platform to showcase the regions of interest to people without the need for them to be physically present, which has had a positive impact on enticing tourists to visit those locations. However, the technology also provides the opportunity to present historical artefacts in a form that accurately represents their original, intended appearance. Three sites of interest were identified in the Lingaun Valley in South East Ireland, wherein virtual representations of site-specific artefacts of interest were created via a multidisciplinary team encompassing archaeology, art history, 3D modelling, design, and software development. The collated information has been presented to users via an augmented reality mobile-based application that provides information in an engaging manner that encourages an interest in history as well as visits to the sites in the Lingaun Valley.Keywords: augmented reality, virtual heritage, 3D modelling, archaeology, virtual representation

Abstract:
This paper explores role of research institutes in creation of support ecosystem for new technology-based ventures. Previous literature introduced research institutes as part of business and knowledge ecosystem, very few studies are available that consider a research institute as an ecosystem that support high-tech startups at every stage of development. Based on a resource-based view and a stage-based model of high-tech startups growth, this study aims to analyze how a research institute builds a startup support ecosystem by attracting different stakeholders in order to help startups to overcome resource. This paper is based on an in-depth case study of public research institute that focus on development of entrepreneurial ecosystem in a developed region. Analysis shows that the idea generation stage of high-tech startups that related to the invention and development of product or technology for commercialization is associated with a lack of critical knowledge resources. Second, at growth phase that related to market entrance, high-tech startups face challenges associated with the development of their business network. Accordingly, the study shows the support ecosystem that research institute creates helps high-tech startups overcome resource gaps in order to achieve a successful transition from one phase of growth to the next.Keywords: new technology-based firms, ecosystems, resources, business incubators, research instutes

Authors: Wael Bakhit, Salma Bakhit
Abstract:
This paper employs a quarterly time series to determine the timing of structural breaks for interest rates in USA over the last 60 years. The Chow test is used for investigating the non-stationary, where the date of the potential break is assumed to be known. Moreover, an empirical examination of the financial sector was made to check if it is positively related to deviations from an assumed interest rate as given in a standard Taylor rule. The empirical analysis is strengthened by analysing the rule from a historical perspective and a look at the effect of setting the interest rate by the central bank on financial imbalances. The empirical evidence indicates that deviation in monetary policy has a potential causal factor in the build-up of financial imbalances and the subsequent crisis where macro prudential intervention could have beneficial effect. Thus, our findings tend to support the view which states that the probable existence of central banks has been a source of global financial crisis since the past decade.Keywords: Taylor rule, financial imbalances, central banks, econometrics

Authors: Hilmi Yazici
Abstract:
Just after Ottoman period, new more homogenic republic was struggling to form a national identity and dealing with the cultural and historical background of the nation. This new republic had an aim of modernization and westernization which started in the late ottoman period. In this process, the culture was an important basis to form a new nation and it clearly put forward that the new citizens of the new national republic are to have a modern and national culture. The result of this aimed change was to find the Turkish culture suppressed among the common people of the Anatolia and to take the western modernization and breed this with national culture. So in this context, we can say that this approach separated the people from ottoman culture and its roots to empower the national identity. Repeatedly, it may be said that Turkish folkloric music was an important basis for the new revolution, on the other hand classical Turkish music was alienated with the idea that it didn’t belong to Turkish culture. So the aim of this study is to determine how these efforts to nationalize a new identity and culture was successful and conscious intervention to folkloric Turkish music became efficient.Keywords: opera, nationalism in music, Turkish music

Authors: Souhila Belabbas
Abstract:
This paper focuses on the Kabyles’ multilingual practices in the UK, within the Kabyle/Amazigh Cultural Organisation in London, on online platforms and at home. The Kabyles have roots in northern Algeria and associate their language, Kabyle, with a pre-Arabized history of northern Africa. Drawing on ethnographic research with this community, this study brings together their post-migration language preservation activisms as well as their dynamic multilingual practices and situational language choice into a dialogue. This shows the enduring significance of the heritage language for social, cultural and historical identity. It also demonstrates that the current survival of the “mother tongue” hinges on multilingual and multi-sited language activisms, which bear the hallmarks of both new creativities and diminishing fluencies in multilingual spaces. These multilingual repertoires also included a range of ideological stances, expressed as cultural, moral, and political attitudes to the “mother tongue” and to other, potentially more dominant, languages in their lives, involving both inclusive and exclusive instances. The Kabyles in the UK practice everyday forms of multilingualism in the dynamic terms whilst making strong identity claims to an endangered heritage language. Crucially, their language contact experiences were not a post-migration novelty but part of their pre-migration lifeworlds. The participants involved in this study shared a commitment to Kabyle identity activism. They expressed this differently, varyingly foregrounding cultural, social or political issues. These differences were related to their North-African cultural background, live, gender, religious and/or political affiliation, as well as to their different migratory trajectories. Among these ethno-conscious individuals, the use of Kabyle was often particularly vibrant in informal domains of casual conversations and mixed in with French, English and often Arabic. During community events and festivals, though, many made special efforts to converse in Kabyle as if to make a point about their commitment to a shared identity.Keywords: ethnography, language ideology, language choice, heritage language, migration trajectories, multilingual repertoires

Authors: Barnali Saha
Abstract:
Dalit writing is the interventionalist voice of the dispossessed subaltern in the cultural economy of the society. As such, Dalit writing, including Dalit poetry, considers the contradictions that permeate the socio-cultural structure historically allocated and religiously sanctioned in the Indian subcontinent. As an epicenter of all Dalit experiences of trauma and violence, the poetics the Dalit body is deeply rooted in the peripheral space socially assigned to it by anachronistic caste-based litigation. An appraisal of Dalit creative-critical work by writers like Sharan Kumar Limbale, Arjun Dangle, Namdeo Dhasal, Om Prakash Valmiki, Muktibodh and others underscore the conjunction of the physical, psychical and the psychological in their interpretation of Dalit consciousness. They put forward the idea that Dalit poetry is begotten by the trauma of societal oppression and therefore, Dalit language and its revitalization are two elements obdurately linked to Dalit poetics. The present research paper seeks to read the problematization of the Dalit agency through the conduit of the Dalit voice wherein the anatomical category of the mouth is closely related to the question of Dalit identity. Theoretically aligned to Heidegger’s notion of language as the house of being and Bachelard’s assertion of a house as an ideal metaphor of poetic imagination and Dylan Trigg’s view of the coeval existence of space and body, the paper examines a series of selected poems by Dalit poetic voices to examine how their distinct Dalit point of view underscores Dalit speech and directs our attention to the historical abstraction of it. The paper further examines how speech as a category in Dalit writing places the Dalit somatic entity as a site of contestation with the ‘Mouth’ as a loaded symbolic category inspiring rebellion and resistance. And as the quintessential purpose of Dalit literature is the unleashing of Dalit voice from the anti-verbal domain of social decrepitude, Dalit poetry needs to be critically read based on the experience of the mouth and the patois.Keywords: Dalit, poetry, speech, mouth, subaltern, minority, exploitation, space

Authors: Benn Van Den Ende
Abstract:
Over the last three decades, there has been an exponential increase in developments in implantable technologies such as the cardiac pacemaker, bionic prosthesis, and implantable chips. The effect of these technologies has been well researched in many areas. However, there is a lack of critical research in security studies. This paper will provide preliminary findings to an ongoing research project which aims to examine how implantable technologies effect the practices of governmentality in the context of security. It will do this by looking at the practices and techniques of governmentality along with different implantable technologies which increase, change or otherwise affect governmental practices. The preliminary research demonstrates that implantable technologies have a profound effect on the practices of governmentality, while also paving the way for further research into a potential ‘new’ form of governmentality in relation to these implantable technologies.Keywords: critical security studies, governmentality, security theory, political theory, Foucault

Authors: Rolando Volzone
Abstract:
The Congregation of Saint Paul of Serra de Ossa (Ossa Mountain) was founded in 1482, originated by the eremitic movement of the homens da pobre vida (poor life men), which is documented since 1366. The community of hermits expanded up to the first half of the 15th century, mostly in southern Portugal in the Alentejo region. In 1578, following a process of institutionalization led by the Church, an autonomous congregation was set up, affiliated in the Hungarian Order of Saint Paul the First Hermit, until 1834, when the decree of dissolution of the religious orders disbanded all the convents and monasteries in Portugal. The architectural evidences that reached our days as a legacy of the hermitical movement in Serra de Ossa, although studied and analysed from an historical point of view, are still little known with respect to the architectural characteristics of its physical implantation and its relationship with the natural systems. This research intends to expose the appropriation process of the locus eremus as a starting point for the interpretation of this landscape, evidencing the close relationship between the religious experience and the physical space chosen to reach the perfection of the soul. The locus eremus is thus determined not only by practical aspects such as the absolute and relative location, orography, existence of water resources, or the King’s favoring to the religious and settlement action of the hermits, but also by spiritual aspects related to the symbolism of the physical elements present and the solitary walk of these men. These aspects, combined with the built architectural elements and other exerted human action, may be fertile ground for the definition of a hypothetical hermitical landscape based on the sufficiently distinctive characteristics that sustain it. The landscape built by these hermits is established as a cultural and material heritage, and its preservation is of utmost importance. They deeply understood this place and took advantage of its natural resources, manipulating them in an ecological and economically sustainable way, respecting the place, without overcoming its own genius loci but becoming part of it.Keywords: architecture, congregation of Saint Paul of Serra de Ossa, heremitical landscape, locus eremus

Authors: Felix Böck
Abstract:
Nowadays, data about learners and their digital activities are collected, which could help educational institutions to better understand learning processes, improve them and be able to provide better learning assistance. In this research project, custom knowledge- and data-driven recommendation algorithms will be used to offer students in higher education integrated learning assistance. The pre-requisite for this is a learner model that is as comprehensive as possible, which should first be created and then kept up-to-date largely automatically for being able to individualize and personalize the learning experience. In order to create such a learner model, a roadmap is presented that describes the individual phases up to the creation and evaluation of the finished model. The methodological process for the research project is disclosed, and the research question of how learners can be supported in their learning with personalized, customized learning recommendations is explored.Keywords: research agenda, user model, learner model, higher education, adaptive educational digital learning environments, personalized learning paths, recommendation system, adaptation, personalization

Authors: Maari Sugawara
Abstract:
This ethnographic research interrogates female masochism within contemporary Japan, focusing on fifteen female BDSM (Bondage, Discipline, Dominance, Submission, Sadism, and Masochism) practitioners who identify as masochists, bottoms, and/or submissives. The study employs semi-structured interviews with these practitioners, representing diverse backgrounds and ages, to explore the intersection of sexuality and individual and/or collective trauma. The study focuses on a specific group of sadomasochists who, as survivors of gender and sexual violence, reenact their trauma through BDSM practices. This exploration draws on feminist performance studies, postcolonial studies, psychoanalysis, and affect analysis to highlight the complexities of female masochism. In a cultural milieu that often reduces female masochism to mere compliance with heteropatriarchy, this study argues that specific masochistic practices transcend submission, serving as vital strategies for confronting trauma and dismantling entrenched cultural narratives. Engaging with Lacan’s concept of feminine jouissance and the notion of "creative masochism" in the context of Japan's proximity to the imperial US, the study facilitates a nuanced exploration of female masochistic enjoyment. The study shows that these practices can act as both a means of survival and a mode of resilience, challenging dominant narratives that portray masochism solely as a form of subjugation, drawing on feminist performance studies, postcolonial studies, psychoanalysis, and affect analysis. It interprets masochism as a complex terrain of affective engagement, where shared suffering and consensual pain foster transformative possibilities. By analyzing BDSM as a cultural site, this research reframes masochism not only as a personal negotiation of pain but also as a broader allegory for Japan’s ongoing geopolitical self-positioning. Central to this analysis is the concept of "creative masochism," which positions masochism as both a metaphor and a practice through which Japan addresses its historical subordination to the United States. This framework allows for a deeper understanding of how participants' lived desires intersect with national narratives, illuminating the relationship between personal experiences and larger socio-political dynamics. It incorporates sadomasochistic metaphors into Japan-U.S. interactions, reflecting underlying patterns of submission, resistance, and cultural negotiation. Additionally, this research examines the effects, affects, and limitations of masochism within the post-WWII Japanese context, providing insights into how masochism can reshape one's relationship with their surroundings. This study challenges the notion that female masochism is entirely subsumed by hegemonic structures, revealing instead that subjects can assert their autonomy within their experiences of pleasure and pain. The consensual enactment of violence within these encounters emerges as a complex and ambivalent process, wherein pain transforms into a generative force for reimagining alternative forms of sociality and belonging. Additionally, the research identifies contradictions and connections between the personal and political, examining how kink practices shape participants' daily lives and identities, and vice versa, highlighting the profound impact of these practices on their sense of self and community. Ultimately, it reaffirms agency in the face of pervasive heteronormative power dynamics, suggesting that masochism can serve as a site of both resistance and redefinition.Keywords: female masochism, BDSM, Japan, masochism, trauma, sexual violence

Authors: A. Bedük, k. Eryeşil, o. Eşmen, m. Onacak
Abstract:
The mobbing is a process that is consisting of negative behaviors such as, systematically and continuously insulting, offending against personal dignity, preventing access to necessary information and disseminating rumors against employee by one or more than one individuals in a work environment through which disturbing the employee physically, psychologically and socially to cause to quit his/her job. This research is aiming to explore the results of mobbing (psychological violence) on employees’ organizational commitment in workplaces. Mobbing takes many forms and is often used to force an employee to leave the work environment. Two different types of scales have been reviewed and revised for use in the research. The Heinz Leymann scale is the first measure, which was developed to define causes and effects, in addition to characteristic behaviors of mobbing. The second scale was developed by Allen and Mayer and indicates levels of organizational commitment. In this research, a questionnaire were applied to 50 employees in a special glass factory in Konya to search mobbing itself and indicate the effects of mobbing to organizational commitments. One of the important findings of this research is that there was no relation between mobbing and general organizational commitment.Keywords: mobbing, organizational commitment, affective commitment, normative commitment, continuance commitment
