experiential learning-teaching model in recreation studies: reflections on implementation
Authors: Schreck Cornelia , Weilbach Theron , Reitsma Gerda
Published: October 2022

The recreation profession is a fast-growing, diverse, career field, creating unique challenges for academic institutions in preparing students. Not all the skills and competencies (graduate attributes) needed by entry-level recreation professionals can be achieved through academic curricula in classroom settings. Experiential learning pedagogy may address these challenges for recreation education. The Twin-Cycle Experiential Learning model (TCELM) can incorporate field- and classroom-based experiential learning into degree programmes. The purpose of this article is to investigate the experience of students in a recreation module that implemented an adapted TCELM. A holistic single-case is reported with qualitative data including student reflections, lecturer reflections and focus group interviews, subject to inductive coding. The merit of both cycles of the TCELM in student learning was examined. Group work and time management were two factors identified that may challenge the implementation of experiential learning. However, both these factors contribute to the development of essential skills for the workplace. It was concluded that the adapted TCELM is practically implementable within a recreation module at a higher education institution. However, attention should be given to student expectations, active learning opportunities and the time spent on experiential learning activities.
Which type of physical activity should be recommended in childhood obesity considering vertebral curves and motor skills?
Authors: Güçhan Topcu Zehra , Ulger Ozlem
Published: October 2022

This paper aims to compare the effects of functional exercises and basketball training on forward head posture, lumbar hyperlordosis, and motor skills of 45 obese children aged 10 years with forward head posture and hyperlordosis. The children were randomly included to the functional exercise, basketball and control groups for 12 weeks. The angles of lumbar lordosis and craniovertebral were recorded as biomechanical variables. Bruininks-Oseretsky Test of Motor Proficiency - Brief Form (BOTMP-BF) was used to determine motor skills of the children. Forty-two children completed the study. All groups had similar angles for lumbar lordosis after 12 weeks (p>0.05), whereas craniovertebral angle significantly decreased in the control group only (p<0.05). Both functional exercise and basketball were effective in improving speed and agility. There was a statistically significant increase in the total BOTMP-BF score of the functional exercise group (p<0.001). Both types of physical activity may be a way of managing the progression of forward head posture, whereas they did not affect lumbar posture. Functional exercises and basketball affected different aspects of motor skills.
PAPR Reduction of OFDM with DFT Spreading Method
Authors: Chandanala Sravanya  , Pasupuleti Sairam  , Barupatla Srinika
Published: October 2022

Future communication systems will demand the transmission of huge amounts of data, therefore will require a highly linear power amplifier. The Orthogonal Frequency Division Multiplexing (OFDM) technique is widely used in multimedia services for providing high data rates and providing high Quality of Service. The transmitter power amplifier's range of operation in a communication system is linear. Signal distortion happens when the input signal's amplitude exceeds the linear range of the transmitter power amplifier. Therefore, the transmitter's input signal has to have a low peak to average power ratio (PAPR). The OFDM system has been recognized as the high rate wireless radio channel transmission. Therefore, it will also be highly beneficial for the high-speed communication system. However, due to the extremely high PAPR issue, using the OFDM system in a communication system is not simple. It results in extremely low power efficiency. Therefore, it is crucial to lower the PAPR in the OFDM system in order to employ it in the communication system. By using a discrete Fourier matrix, the Discrete Fourier Transform spreading strategy may significantly lower the PAPR of an OFDM signal. This paper describes the PAPR reduction approach in OFDM signals and examines the effectiveness of OFDM.

Teniendo como pauta la secuencia narrativa de la unidad (cc. 19-24) se resaltarán los elementos tradicionales correspondientes a cada procedencia, oral y escrita, para remarcar la entronización del sefer como parte dinámica de la liturgia de renovación de la alianza y el cierre de la celebración. Estos aspectos llevarán a inferir algunas conclusiones que permitan valorar la hipótesis de estudio y aporten reflexiones de orden pastoral.
Voltage Stability Analysis during Power Network Node Type Conversion
Authors: Yi Tao
Published: October 2022

During the analysis of the power network, a node type conversion will occur under certain extreme conditions. This brings the problem of stability of the power system voltage. This article extracts the characteristic equation of the system voltage critical point by establishing a node voltage-branch current to the power network equation. Therefore, the corresponding solution equation group was in the conversion process of the PQ-PV node. Through this equation group, the difference in the difference between the voltage value of the node and the critical point voltage is formed to determine the system stability after the node type conversion is converted. In the process of calculating the voltage critical point, the improved Newton iteration method is used to avoid Jacques bizarre. This method allows calculations to smoothly reach a state of convergence. The simulation calculation shows that the method proposed in this article is correct and effective.

A Cláusula Penal nos Contratos de Incorporação Imobiliária
Authors: Ribeiro Pereira Silva João Gabriel
Published: October 2022

A regulamentação da resilição unilateral do contrato de compra e venda de imóveis submetido ao regime de incorporação imobiliária, realizada pela Lei nº 13.786 de 27 de Dezembro de 2018, não afasta o dever do judiciário de controlar a proporcionalidade da cláusula penal, mesmo que submetida aos limites contidos no novo diploma legal. O presente trabalho procura oferecer ferramentas para que tal controle seja feito de maneira objetiva, através da decomposição analítica dos elementos que compõem as perdas ordinariamente advindas de tal modalidade de extinção contratual e atribuindo a elas peso de 20% sobre a totalidade da cláusula penal. Objetiva-se, com isso, fornecer critérios para tomada de decisão que ofereça padrões mais claros, evitando-se subjetivismo e decisões contraditórias.
O Paradoxo nos Princípios Pacta Sunt Servanda e Rebus Sic Stantibus em Contratos de Natureza Empresarial
Authors: Rodrigues Leonel Cezar , Richardo Rodolpho Luiz Maderic , Dubois Marcio
Published: October 2022

Por muito tempo, no Codex dos países adotantes do sistema positivista de normas e mais especificamente no Brasil, o princípio da força obrigatória (pacta sunt servanda) tem determinado o formato da resolução dos contratos inadimplidos: o devedor tem que pagar suas obrigações ou arcar com o ônus do inadimplemento. Nos últimos cem anos, no entanto, cresceu sobremaneira o senso dos direitos individuais (físicos e corporativos), levando maior racionalidade às resoluções contratuais em contextos alterados, econômica ou socialmente. Por seu princípio obrigacional (pacta sunt servanda) a lei está para ser cumprida, mas por seu princípio funcional em direção à acomodação dos interesses coletivos, sua flexibilização, mesmo que em contextos alterados, cria um paradoxo conceitual. O efeito compulsivo da obrigação para execução dos contratos é o elemento que impõe uma aparente contradição na lógica da lei, diante do instrumento flexibilizador (rebus sic stantibus) acomodante dos interesses.  O fundamento resolutivo, porém, encontra-se na aproximação de suas polaridades de forma a que tais princípios passem a complementar-se. Assim, o princípio flexibilizador da lei não constitui apenas uma exceção ao primeiro, mas é muito mais que isso. Esse ensaio tem por objetivo demonstrar o paradoxo conceitual e sua justificação pela complementariedade entre os dois princípios: obrigacional e flexibilizador. Para tanto, valemo-nos aqui da dialética argumentativa, com base na literatura especializada, possibilitando demonstrar que a resolução dos contratos, quando em condições adversas, requer equilíbrio na aplicação objetiva dos dois princípios.

CONCEPTUAL MAPPING MODEL ACROSS LANGUAGES: A TEST IN VIETNAMESE LANGUAGE
Authors: Nguyen Vi Thong
Published: October 2022

The conceptual metaphor, LOVE IS A JOURNEY, has been identified as a process of mapping based on the Conceptual Metaphor Theory (CMT) proposed by Lakoff and Johnson (1980). However, Ahrens (2002) pointed out several problems that the CMT may encounter, especially in setting parameters to be experimentally tested. Ahrens (2002) proposed the Conceptual Mapping Model (CMM) to investigate metaphor expressions by identifying three mappings between the source domain and the target domain: entities, qualities, and functions. After an analysis, the reason for these mappings, called a mapping principle, is indicated. In particular, the CMM can predict the processing of conceptual metaphors in terms of conventional and novel metaphors. This study is intended to test whether the CMM can perform well across languages through the experimental rates of acceptability and interpretability for different types of metaphors. Fifty Vietnamese native speakers were recruited. Each participant judged (on a Likert scale of 1-7) the levels of acceptability and interpretability of three conceptual metaphors in Vietnamese: LIFE IS A BOOK, HAPPINESS IS LIGHT, and LOVE IS FIRE. Each conceptual metaphor consists of six types of sentences, including (a) Literal pair to B, (b) Conventional metaphor, (c) Literal pair to D, (d) Novel metaphor that follows the mapping principle, (e) Literal pair to F, and (f) Novel metaphor that does not follow the mapping principle. The results of t-tests show that in terms of both acceptability and interpretability, conventional metaphors are ranked higher than novel metaphors. The results also indicate that novel metaphors that follow the mapping principle are rated higher than those that do not. Therefore, the mapping principle can constrain the image schemas so that any image that does not belong to the schemas can affect the processing of metaphors.
Foraging for the self: Environment selection for agency inference
Authors: Perrykkad Kelsey , Robinson Jonathan E. , Hohwy Jakob
Published: October 2022

Sometimes agents choose to occupy environments that are neither traditionally rewarding nor worth exploring, but which rather promise to help minimise uncertainty related to what they can control. Selecting environments that afford inferences about agency seems a foundational aspect of environment selection dynamics – if an agent can’t form reliable beliefs about what they can and can’t control, then they can’t act efficiently to achieve rewards. This relatively neglected aspect of environment selection is important to study so that we can better understand why agents occupy certain environments over others – something that may also be relevant for mental and developmental conditions, such as autism. This online experiment investigates the impact of uncertainty about agency on the way participants choose to freely move between two environments, one that has greater irreducible variability and one that is more complex to model. We hypothesise that increasingly erroneous predictions about the expected outcome of agency-exploring actions can be a driver of switching environments, and we explore which type of environment agents prefer. Results show that participants actively switch between the two environments following increases in prediction error, and that the tolerance for prediction error before switching is modulated by individuals’ autism traits. Further, we find that participants more frequently occupy the variable environment, which is predicted by greater accuracy and higher confidence than the complex environment. This is the first online study to investigate relatively unconstrained ongoing foraging dynamics in support of judgements of agency, and in doing so represents a significant methodological advance.
Non-parametric mixture modeling of cognitive psychological data: A new method to disentangle hidden strategies
Authors: Archambeau Kim , Couto Joaquina , Van Maanen Leendert
Published: October 2022

In a wide variety of cognitive domains, participants have access to several alternative strategies to perform a particular task and, on each trial, one specific strategy is selected and executed. Determining how many strategies are used by a participant as well as their identification at a trial level is a challenging problem for researchers. In the current paper, we propose a new method – the non-parametric mixture model – to efficiently disentangle hidden strategies in cognitive psychological data, based on observed response times. The developed method derived from standard hidden Markov modeling. Importantly, we used a model-free approach where a particular shape of a response time distribution does not need to be assumed. This has the considerable advantage of avoiding potentially unreliable results when an inappropriate response time distribution is assumed. Through three simulation studies and two applications to real data, we repeatedly demonstrated that the non-parametric mixture model is able to reliably recover hidden strategies present in the data as well as to accurately estimate the number of concurrent strategies. The results also showed that this new method is more efficient than a standard parametric approach. The non-parametric mixture model is therefore a useful statistical tool for strategy identification that can be applied in many areas of cognitive psychology. To this end, practical guidelines are provided for researchers wishing to apply the non-parametric mixture models on their own data set.

PARAMETERS AFFECTING THE TRANSIENT RESPONSE OF VERTICAL PIPE ELECTRODES TO IMPULSE EXCITATION
Authors: Tomislav Barić  , Zijad Haznadar  , Sead Berberović
Published: October 2022

In this article, an application of the transmission line theory is presented for analyzing various parameters that affect the transient response of ground electrodes. In order to simplify the presentation and the interpretation of the results obtained, a vertical buried pipe electrode was chosen as the ground electrode. The ground electrode is connected to a grounding conductor, the upper part of which is connected to an ideal current source. The impact of the overhead geometry of the grounding conductor upon the transient response of the ground electrode is analyzed by varying the length of the grounding conductor. The ideal current source generates a normalized wave shape current impulse, a so-called double exponential impulse. The effect of the time to peak of the impulse (steepness of the rising edge of the peak current) on the transient response of the ground electrode is analyzed by varying the current wave shape parameters. The impact of soil parameters on the transient response of the ground electrode is also analyzed. The soil is modeled as a single-layer homogeneous isotropic semispace. The soil-air boundary is represented by a plane. The results obtained are presented graphically and discussed.
LIBERALIZATION OF THE ELECTRICITY MARKET ‒ IS IT MEETING EXPECTATIONS?
Authors: Ivan Tominov
Published: October 2022

The fundamental declarative goal of the reform of the electrical power industry, i.e. the liberalization of the electricity market, has been and remains to raise the efficiency of the electrical power sector, primarily for the purpose of increasing the competitiveness of the economy. The following had been expected from the liberalization of the electricity market: reduction in the price of electricity, improvement in the level of service, reduction in the differences in prices among countries, the option for each customer to choose a supplier, and an increase in the efficiency of the sector by reducing the need for the construction and maintenance of reserve capacities. This work presents an investigation and analysis of the extent to which these goals for the liberalization of the electricity market have been achieved and are achievable, how successful the shift has been from a monopolistic organizational structure of the electrical power industry to a competitive structure, i.e. whether the liberalization of the electricity market has met expectations. Based upon assessment of the cost-benefit ratio from the liberalization of the electricity market, it can be said that liberalization will not achieve the primary goal for which it was initiated, which is reduction of the price of electricity. The goal of making prices uniform was also not achieved because there are still great differences in the prices of electricity among countries. There has been no significant shift in the organizational structure of the electrical power industry from monopolistic to competitive. Positive shifts have been achieved in raising the level of the quality of services, increasing the efficiency of the sector by reducing the need for the construction and maintenance of reserve capacities, and in the formal opening of the markets. These research findings confirm the hypothesis presented in the introduction to this work that the primary goals of the liberalization of the electricity markets have not been achieved. It can be concluded that the liberalization of the electricity market has not fulfilled expectations. Moreover, according to the current status of the reforms and the tendencies in these processes, these goals have not been achieved in the manner in which the initial reforms were imagined and defined.
ASSESSMENT OF RISK TO DISTRIBUTION WORKERS
Authors: Pavle Filko
Published: October 2022

This article presents an analysis of the risk to workers maintaining the medium-voltage facilities of distribution companies, as derived from a series of investigations (injuries at work, time spent on equipment maintenance, ground faults and failures in the grounding system) and represents a group of all the relevant information collected on hazards to workers. The importance of this study is that it is basically concerned with failures, stoppages and interruptions but also repairs (the forecasting, detecting and eliminating of failures), maintenance, replacement, advancements and improvements in the technical systems, as well as the consequences of failures in technical systems and the surroundings thereof. Electricity distribution workers spend most of their working time on the tasks of maintaining electric power facilities, i.e. electricity networks and medium-voltage and low-voltage electric power facilities. While they are working, they are in a potentially hazardous environment that can endanger their health and lives. Naturally, they must be trained to work in a safe manner and use protective equipment. This does not completely eliminate the hazards but in this way the potential for injury and the severity thereof are reduced. All companies, including those engaged in the distribution of electrical energy, take costs into account, much of which are for human labor. Worker injury during working time is also an expenditure, due to sick leave and potential damages, which will be increasingly significant factors in company operations. Therefore, it is important to review all the potential hazards that can endanger the health and life of a worker during maintenance work. The management of such risks will become a growing task for all companies, less for humane reasons than for keeping costs under control.
THE NEUTRAL CONDUCTOR VOLTAGE IN A MEDIUMVOLTAGE NETWORK DURING A GROUND FAULT
Authors: Matislav Majstrović  , Hrvoje Olujić
Published: October 2022

Of all the ground faults that can occur in medium-voltage networks from the standpoint of human and equipment safety, the most problematic is a ground fault in a medium-voltage/low-voltage substation. The grounding system of a lowvoltage network is directly connected to the grounding electrode of the substation. Therefore, each increase in the potential of the grounding electrode of the substation is transmitted directly via the neutral conductor into the customer’s installation. For these reasons, in this article a detailed investigation is presented of the problem of determining the neutral conductor voltage in a low-voltage network during a ground fault at the medium-voltage level in a supply substation that is an element of a medium-voltage network with an isolated neutral point (star point). A computer model is presented for the analysis of the neutral conductor voltage in actual distribution networks. Two characteristic distribution networks located on karstic terrain are analyzed. The results obtained are compared to the results of measurements.

SHORT-TERM LOAD FORECASTING BY USING THE ARTIFICIAL NEURAL NETWORK MODEL
Authors: Krešimir Tačković  , Srete Nikolovski  , Vedran Boras
Published: October 2022

The article describes a model for short-term load forecasting by using the artificial neural network, and its application to load forecasting for a concrete distribution area. The artificial neural networks are mostly used in solving the problems of classification and prediction when the relations between input and output variables are highly complex and hard to describe exactly. Considering the stochastic nature and the major impact of weather conditions (temperature, humidity, wind, etc.) on electricity consumption, the application of artificial neural networks is suitable for short-term forecasting the load of an electric power system (EPS). Furthermore, the article describes the used models of artificial neural networks for seasonal and multiple daily load forecasts and presents the load forecast results for a distribution area supplied over the busbars of the 110/x substation at the HEP Elekroslavonija Distribution System Operator (HEP ODS).
Managing Risk in Dynamic Conditions: Emerging Crises, Changing Technologies, and the Collective Capacity to Learn
Authors: Comfort Louise K. , Wang Wen-Jiun
Published: October 2022

Governing unexpected, extreme events requires a fundamental change in the design of planning processes and responsibilities to enable communities to manage novel risks in sustainable ways. The challenge is to create continuous learning processes for communities that include participants at diverse levels of knowledge, skill, vulnerability, and commitment to reducing risk not only for themselves, but for the whole community. To investigate the problem of collective learning under stress, we analyzed processes of organizational learning in the operational context of Taiwan over a series of extreme events, 1999–2020. While collective learning did occur in Taiwan, it is not clear that sustainable management of novel risks has been achieved. Finding the balance between social coherence and system control likely needs to be recalibrated for each new event.

Applied big data technique and deep learning for massive open online courses (MOOCs) recommendation system
Authors: Sakboonyarat Siriporn , Tantatsanawong Panjai
Published: October 2022

As traditional recommendation techniques suffer from scalability problems resulting in poor-quality recommendations, they cannot be effectively used on big data. With the immense amount of emerging online learning resources nowadays, it has become harder for users to find and select their preferred content. Similarly, course recommendation systems also face an information overload problem. Most recommendation systems are created based on their own learning management systems and can only be used with those systems. Furthermore, the storage and processing of these systems cannot be updated, which makes them unsuitable for real-world problems, because data is continuously changing and emerging. Focusing on the aforementioned problem, in this study, we propose a novel online recommender system, namely, MCR-C-FGM. It runs on clusters and is trained with a fit-generator method which uses the Apache platform to distribute the processing of large datasets along with a clustering model created by a Deep Neural Network and Long Short-Term Memory. The network is trained with the fit-generator method. The test results with real MOOCs data from Harvard University and MIT, which were published in edX, show a high precision rate of 75%, an accuracy rate of 76%, and a recall rate of 78% in the evaluation processes. The time efficiency during the training process improves by 35% compared to the non-clustering model. Moreover, the MCR-C-FGM is capable of being scaled out, which allows it to efficiently support big data.
Compact Genetic Algorithm with Quantum-Assisted Feasibility Enforcement

The local optima problem is one of the biggest obstacles in compact genetic algorithms since each bit in the problem encoding string is independent of the others. We propose a quantum-assisted compact genetic algorithm that uses a quantum amplitude amplification technique in the selection process to circumvent the said problem. In addition to using elitism mechanics where a single best candidate solution is kept to drive the probability vector, the amplitude amplification subroutine also acts as a mutation operator which, with high probability, enforces the constraint that the newly generated candidate is a feasible solution. We demonstrate this idea by applying the algorithm to the traveling salesman problem of size 3 and 4 cities on IBM Qiskit simulator to show how one would construct the quantum circuit and how to encode the optimization problem into quantum states via Ising spin model encoding. We then show space and time complexity analysis based on the quantum circuit model. Finally, we discuss the number of qubits required for encoding, gate counts in the circuit model, and the practicality of applying this to a small-scale devices in the future.

The objective of this study was to determine the kinds of English Dictions commonly occured in the students Facebook status. It was the analysis on the use of English of the students of Pamane Talino college of Education and the reasons behind the writing of the dictions by students STKIP Pamane Talino Landak Regency. The method used was a descriptive qualitative research method. The subjects in this study were English students at STKIP Pamane Talino, Landak Regency, for the 2019&2020 year of study, totaling 30 students. Sources of data were: (1) sources (informants), (2) places and events, (3) documents. Data collection techniques used in this study are (1) documents, (2) interviews. The results of this study are: (1) The types of English diction used by the students are as follows: (a) formal diction, (b) informal diction. The college students tend to use informal diction (93.3%) rather than formal diction (6.7%) in writing status on their Facebook. It is because writing informal diction is easy, simple, and free to express their feeling and thinking. Many of them claimed that have limited vocabulary. This research also showed the background of the students’ reason in writing informal diction on their Facebook status is because they want to share their feeling. (2) The reasons of writing English diction by students are (a) The students need to share their experience and situation in their daily life, (b) The students inspired from words of motivation and lyrics of song, (c) The students want to express the current idea that pop in their mind. This is because most of the students tend to write in English to practice their writing skill and vocabulary.Keywords: Facebook, Type of Diction

Data collection techniques used tests, questionnaires, and observations. The data analysis used a two-way ANOVA.  The results show that: (1) There is a differentmotivation in Vocabulary Mastery in proving withan average result of 67,7% in the medium category (2) Media influence to Value (sig = 0,047 <0, 05), while motivation does not affect the value (sig = 0.424> 0.05). (3) This study also finds a difference of effectiveness between the application of flashcards and scrabble media with the mean of experimental class gains 82,17 and mean of control class gains 68,80. Moreover, the result of observation shows the students of class X MIA are active and X IIS A are ranged into a very active, active, and quite active. Keywords: flashcard and scrabble media, vocabulary mastery, learning motivation
La puissance et la grâce
Authors: Brahami Frédéric

Les thèses que Proudhon développe sur les femmes, l’amour et le mariage n’expriment pas seulement sa misogynie personnelle, elles remplissent aussi une fonction centrale dans sa théorie de la justice. Le mariage en effet, qui suppose la supériorité de l’homme sur la femme, est l’institution originelle sans laquelle la dignité humaine aboutirait à la guerre de tous contre tous. Condition de leur complémentarité, l’inégalité foncière entre femmes et hommes sanctifiée dans le mariage rend seule possible l’émergence d’une société d’hommes libres et égaux.
La formation médicale dans le contexte de la pandémie de covid-19 : impacts et enjeux de l’apprentissage
Authors: Pachá Patrícia Maciel , Aloisio Alves Camila
Published: October 2022

Le but de cet article est de présenter les impacts provoqués par la pandémie de covid-19 dans la formation médicale, dans le contexte de la Faculté de médecine de Petrópolis (Brésil), en mettant l’accent sur la façon dont les enseignants de l’unité curriculaire d’ophtalmologie ont mené le processus d’adaptation du cours pour mettre en œuvre un modèle d’EAD (enseignement à distance) auprès de 82 étudiants. Selon les résultats, issus de l’analyse de contenu des réponses des étudiants aux questions ouvertes de l’évaluation du cours et de l’autoévaluation, il est possible d’identifier que, malgré les impacts négatifs provoqués par la pandémie, les professeurs ont pu mettre en place des stratégies favorisant l’apprentissage. Mais des questions demeurent sans réponse concernant les lacunes laissées par les expériences pratiques non vécues, l’acquisition des compétences corrélées et le développement d’apprentissages expérientiels. Répondre à ces questions peut offrir des pistes pour l’amélioration de la formation dans le contexte actuel de transformations sanitaires, éducationnelles et sociales.
