A Systematic Review of the Literature on Societal Attitude towards Inclusive Education In North-East India
Authors: Kalita Dr. Barsha , Khanikar Labanya
Published: March 2022

Disability is a societal issue. Societal attitude often stands as a determining factor which determines the extent to which the physical, emotional and societal needs of a person with disability is met. Education of disabled children is one of the areas which have been largely impacted by the societal attitude. Therefore the concept of inclusive education emerged. According to UNICEF’s Report, on the Status of Disability in India (2000) states that there are around 30 million children in India suffering from some kinds of disability. Besides the Sixth All-India Educational Survey (NCERT, 1998) reports, that out of India’s 200 million school-aged children (6-14 years), 20 million require special needs education. While the national average for gross enrolment in school is over 90 per cent, less than five per cent of children with disabilities are in schools. Therefore, certainly the idea of inclusive education is highly relevant in North-east India, where differences in ability are seen as a threat, rather than a source of richness and diversity. Further there is lacuna of research about the impact of societal attitude on inclusive education in North-east India. Therefore, the objectives of the study are to review the extent of implementation of inclusive education in North-East India and to identify how societal attitude act as a barrier in implementation of inclusive education. Further, this paper also suggests how social work as profession can change societal attitude to strengthen the process of inclusive education. The ontological framework on which the study is based is that social construct normalizes the exclusion faced by children with disability in education. The epistemological assumption is that the relationship between societal attitude and inclusive education can be understood by in-depth review of secondary literature. The logic of procedure as emanating from the theoretical framework is predominantly deductive. Further, the study design includes systematic review and synthesis of related literature. The paper is divided into eight sections namely, introduction, rationale of the study, objectives of the study, methodology, literature review, critical analysis of literature review, suggestion and conclusion.

Authors: Osemudiamen Inegbedion Daniel , John Nsikan Efiok
Published: March 2022

Electronic retailing has received increased attention from entrepreneurship management and marketing researchers lately. However, its application in electronic marketing of agricultural products in Nigeria is under- researched. In this paper, empirical analysis of e-retailing application by agribusiness entrepreneurs was carried out. The study was carried out in Lekki/Epe free-trade zone in Lagos State. Therefore, the stud investigated the level of awareness and reception of e-retailing among livestock products farmers, the extent of application of e-retailing platforms, the challenges and limitations of application, and whether or not e-retailing has any significant benefits for livestock farming and agribusiness enterprises in Nigeria. The research adopted the survey descriptive design with target population of over 500 rural farmers involved in processed poultry products. A random sample of 160 respondents participated in the study, and relevant data was collected by administering structured questionnaire on participants. The Results showed that e-retailing application among rural agribusiness entrepreneurial farmers is still at its infancy despite the attendant benefits. Various factors are responsible for this situation, namely: insufficient online product and pricing information; high cost of accessing internet broadband; fear of internet insecurity and cyber fraud; fluctuating power, and lack of government support. As part of the recommendations, there is need to raise agribusiness entrepreneurial awareness to the huge potentials of e-retailing.

The term 'unorganised' is frequently used in the Indian context to refer to the large
number of women and men working in various occupations. Home-based work (e.g.,
rolling papads and beedis), self-employment (e.g., selling vegetables), employment in
household enterprises, small units, on land as agricultural workers, labour on
construction sites and domestic work. The present study was designed with objective
to identify the problem that women face as unorganised labour and to bring to light
the plight of female workers in India. For this purpose 100 women stone crushers
between the age range of 15 and 50 were selected from Patiala district. A self
designed interview schedule was used to collect data and it was found that majority
of the women are working in pathetic conditions and have low work satisfaction.

Building Collaborative Test Practices: Design Ethnography and WOz in Autonomous Driving Research
Authors: Osz Katalin , Rydström Annie , Fors Vaike , Pink Sarah , Broström Robert
Published: March 2022

This article outlines a novel way of performing experimental“Wizard of Oz”(WOz) User Experience (UX)research that specifically targets driving in different levels of self-driving modes. The reasons for exploring the possibilities of combining experimental and ethnographic WOz-testing have been twofold. On the one hand, this mixed-method approach responds to a growing body of critique concerning how the WOz test is biased by the claim that it explores real-life behaviour in an experimental setting. On the other hand,our approach also meets the demands for innovative research methodologies that can contribute to deeper understandings of how to better evaluate and account for human expectations and experiences when automated technologies become integrated in everyday life contexts. This knowledge is inevitable for a broader understanding of the overall user experience and expectations of autonomous driving and, more specifically, building an interdisciplinary collaborative testing approach.
Exploring Intended and Unintended Uses of (e)Books as Design Inspiration for Ambient Displays in the Home
Authors: Moser Christiane , Aslan Ilhan , Neureiter Katja , Randelshofer Ivana , Sundström Petra , Tscheligi Manfred
Published: March 2022

Books at home are used for more than reading, such as collecting them, using them as decoration, or expressing personality. In order to get a better understanding of intended and unintended uses of printed books, we conducted seven book tours in different homes followed by semi-structured interviews. This data was complemented with a large-scale online survey with 300 respondents. We describe our findings focusing on storage, sorting, decoration, and self-expressionand how they inspired us to develop a digital bookshelf (ambient display) as a technology probe to explore decoration with eBooks in the home. We argue for a transition from decoration with printed books to eBooks as design inspiration that does not simply replicate a bookshelf as ambient display, but makes eBooks tangible by combining users’ habits with qualities of digital material.
The Merits of Situated Evaluation as an Alternative UX Evaluation Method to Understand Appropriation
Authors: Börjesson Peter , Barendregt Wolmet , Eriksson Eva , Torgersson Olof , Arvidsson Liza , Persson Linda
Published: March 2022

Oftentimes, technologies are not used in the ways designers had initially envisioned. Instead, people adapt technologies to their own needs, a phenomenon called ‘appropriation’. Appropriation is an important aspect of User Experience design, related to the situatedness and dynamics of the design, recognizing not only that initial needs and requirements may change over time, but also that a design may change the environment that it was designed for. Appropriation can also contribute to a sense of ownership as people use a design in their own way, sometimes in ways the designer did not intend. However, commonly used User Experience evaluation methods often do not focus on the appropriation process of a technology. Situated Evaluation is an approach that does focus on appropriation, although it has not yet been used extensively in the UX field. In this paper, we therefore present and critically discuss our use of the Situated Evaluation approach for the evaluation of a specific tool that aims to enhance the communication between children, parents, and teaching staff in special education. By presenting this case, we hope to inform other UX researchers and designer about the potential of the approach to understand appropriation is an important factor in UX design.
Unexpected Artifact – A Modding Interface Design
Authors: Guerra Lopes Arminda
Published: March 2022

Human Computer-Interaction (HCI) has been handled in different ways, which permittedtointerpret the theories, methods and practices according the chosen approach. Some considerations are presented about HCI approaches over the years, and the adopted pedagogical tactics to teach HCI disciplines is described. HCI was taught following the method of teaching / learning pointed to student-centered, supported by incentives for self-learning and integration of knowledge, preparing students for lifelong learning. The student was confronted with a set of theoretical and practical problems, based on real cases, for which they needed to present solutions. The attitude towards the students was challenging them to deal with creativity and how it was affected/supported by technology. The case that we describe in this paper concerns an artifact – a microwave –, which was modified to function differently from what it was built for. We present an example case where students were free to demonstrate their creativity and develop an artifact based on the concept of modding.

Authors: Koskinen Hanna , Norros Leena
Published: March 2022

This paper describes the use of functional models in a participatory design process to facilitate user involvement in complex system design. The particular case study presented here is the design of Future Internet-enabled farming system to address the global food chain challenges. Taking an end-user perspective during the development of systems and infrastructures in order to assist people in their work and everyday lives sets new challenge for complex system design. In extending the use of functional models by adopting the human factors engineering perspective, we show how future practice was made tangible and subject to the value estimations of a variety of end-user groups. In the food chain related development project, functional models facilitated the creative agency of the food chain actors and enabled a participatory design process in which the agricultural engineers and the food chain actors collaborative worked on a vision of future farming.

Authors: GRABOWSKI Andrzej , WODZYŃSKI Mieszko
Published: March 2022

Resilience of Critical Infrastructure (CI) facilities defined as a capacity for further operation even upon changes that may result from natural or human-made disasters is extremely important from the perspective of functioning of society. Resilience of critical infrastructure facilities may be developed by taking such activities as introducing changes to their structure based on results of simulations of functioning of CI facilities. Another solution is to make use of computer simulations for better preparation of persons responsible for the functioning of CI facilities. This article describes a reference CI facility with potential scenarios of development of emergency situations and with a set of optional courses of an emergency situation. The scenarios were used to prepare a training application based on virtual reality techniques with an interface allowing a wide spectrum of interactions with a virtual environment, including commands issued to other employees, to be executed.
Evaluation of a Novel Method of Fuse Programming Based on the Number of Projectile Revolutions
Authors: FURMANEK Wojciech , GACEK Józef , JĄCZEK Grzegorz P.
Published: March 2022

This paper presents an innovative method of programming fuses for airburst munitions based on the principle of counting the number of revolutions a projectile makes around its centre line along the flight trajectory in order to determine the distance travelled by the projectile. The proposed innovative method of fuse programming was compared to other known methods of fuse programming based on the results of a computer simulation of firing a 40 mm grenade launcher under near-real conditions. For this purpose, a methodology was developed for external ballistic calculations using a mathematical model of the three-dimensional motion of a non-deformable flying object considered to be a rigid body with six degrees of freedom in an ISO 1151 coordinate system.
Simulations were carried out taking into account actual firing conditions for 40 mm grenade launcher ammunition armed with fuses programmed by each of the methods evaluated. Targets located at various distances were fired upon and the level of scatter of actual fuse ignition points relative to the expected fuse ignition point was evaluated for each programming method. It was concluded that the method of determining the distance travelled by the projectile with the principle of counting the projectile’s revolutions under real conditions resulted in a scatter of the fuse ignition points greater than with the time delay-based methods. In conclusion it was observed that the method of determination for the revolving projectile based on counting the projectile’s rotations along the flight trajectory did not guarantee the required precision of the fuse ignition point locations. This means that the application of the methods to determine the distance of projectile burst along the flight trajectory did not increase the effectiveness of airburst fragmentation munitions.
Recognition of Human Inner Emotion Based on Two-Stage FCA-ReliefF Feature Optimization
Authors: Pan Lizheng , Wang Shunchao , Yin Zeming , Song Aiguo
Published: March 2022

Currently, there is a growing interesting in emotion recognition. Representation of emotional states is a very challenging issue. Considering the calculation cost and generalization capability for practical application, a series of features which contain common time and frequency domain are extracted from physiological signals to represent different emotional states. To reduce feature dimensionality and improve the emotion recognition accuracy, a two-stage feature optimization method based on feature correlation analysis (FCA) and ReliefF algorithm is proposed to select critical features. Firstly, FCA is employed to analyze the redundancy between features, then ReliefF is adopted to analyze the correlation between features and categories, and the optimal feature subset is obtained using the two-stage FCA-ReliefF feature optimization method. Support vector machine is employed as the classifier to evaluate classification performance in this investigation. The effectiveness of the method which is proposed is validated by testing on two publicly available multimodal emotion datasets, Augsburg Biosignal Toolbox (AuBT) and Database for Emotion Analysis Using Physiological Signals (DEAP). Compared with recent similar reported studies, the method developed in this research for emotion recognition is stable and competitive, and its accuracy reaches to 98.40% (AuBT) and 92.34% (DEAP).

Authors: Pacevič Ruslan , Kačeniauskas Arnas
Published: March 2022

The paper presents the memory-saving GPU algorithm of the infinite grid method with various hash functionsfor contact search in discrete element computations. The implemented hash table of fixed size has the addedbenefit of allowing the grid to be potentially infinite in size, which is particularly suitable for a large numberof discrete particles, moving in large computational domains with empty regions. Research on the applicationof various hash functions and hash table sizes was performed to preserve the computational performance ofthe developed memory-saving GPU algorithm and its OpenCL implementation. The performance of the developed software was evaluated by solving the hopper fill and discharge as well as the artificial avalanche problemson the NVIDIA® Tesla™ P100 GPU. The performance achieved by using the memory-saving implementationof contact search was compared with that attained by using the standard implementation of the uniform gridmethod. The performed analysis revealed that the developed GPU algorithm and its OpenCL implementationreduced the GPU memory consumed by the uniform grid method up to 69.7 times, which resulted in the contactsearch memory equal to 1.86% of the total memory required by DEM computations. Moreover, the applicationof the Morton hash function and the proper hash table size allowed for preserving high computational performance of the infinite grid method and the developed GPU software.

DARAPI proves beneficial not only to thenaïve users but also to the experts by saving their time and efforts needed in understanding the data.
A Comprehensive Review of Deep Learning Techniques for the Detection of (Distributed) Denial of Service Attacks
Authors: Malliga S. , Nandhini P. S. , Kogilavani S. V.
Published: March 2022

(Distributed) Denial of Service (DoS/DDoS) attacks are performed to bring down a target by flooding it withuseless traffic. Because the DoS/DDoS attackers often change their styles and attack patterns, the nature andcharacteristics of these attacks need to be examined cautiously. Developing mechanisms to detect this menaceis a challenging task. Recently, deep learning has played a major role in the growth of intrusion detection solutions. In recent years, significant attempts have been made to construct deep learning models for counteringDoS/DDoS threats. In this review, we provide a taxonomy of DoS/DDoS attacks and deep learning-based DoS/DDoS detection approaches. Then, the article focuses on the recent (from 2016 onwards) defensive methodsagainst DoS/DDoS attacks that exploit the advantages of deep learning techniques and discusses the key features of each of them. As datasets are imperative for deep learning techniques, we also review the traditional and contemporary datasets that contain traces of DoS/DDoS attacks. The findings from the review articles are as well summarized and they urge that more effort be made to strengthen the existing state-of-the-art approaches to coping with the dynamic behavior of the attackers. The imbalances in the surveyed articles are also highlighted. Finally, we outline a few key research directions that will need additional focus in the near future to ensure good security against DoS/DDoS attacks using deep learning approaches.
Multivariate Microaggregation of Set-Valued Data
Authors: Imran-Daud Malik , Shaheen Muhammad , Ahmed Abbas
Published: March 2022

Data controllers manage immense data, and occasionally, it is released publically to help the researchers toconduct their studies. However, this publically shared data may hold personally identifiable information (PII)that can be collected to re-identify a person. Therefore, an effective anonymization mechanism is required toanonymize such data before it is released publically. Microaggregation is one of the Statistical Disclosure Control (SDC) methods that are widely used by many researchers. This method adapts the k-anonymity principle togenerate k-indistinguishable records in the same clusters to preserve the privacy of the individuals. However,in these methods, the size of the clusters is fixed (i.e., k records), and the clusters generated through these methods may hold non-homogeneous records. By considering these issues, we propose an adaptive size clusteringtechnique that aggregates homogeneous records in similar clusters, and the size of the clusters is determinedafter the semantic analysis of the records. To achieve this, we extend the MDAV microaggregation algorithm tosemantically analyze the unstructured records by relying on the taxonomic databases (i.e., WordNet), and thenaggregating them in homogeneous clusters. Furthermore, we propose a distance measure that determines theextent to which the records differ from each other, and based on this, homogeneous adaptive clusters are constructed. In experiments, we measured the cohesiveness of the clusters in order to gauge the homogeneity ofrecords. In addition, a method is proposed to measure information loss caused by the redaction method. In experiments, the results show that the proposed mechanism outperforms the existing state-of-the-art solutions.

The vehicle routing problem with time windows (VRPTW) as one of the most known combinatorial operations (CO) problem is considered to be a tough issue in practice and the main challenge of that is to find the approximate solutions within a reasonable time. In recent years, reinforcement learning (RL) based methods have gained increasing attention in many CO problems, such as the vehicle routing problems (VRP), due to their enormous potential to efficiently generate high-quality solutions. However, neglecting the information between the constraints and the solutions makes previous approaches performance unideal in some strongly constrained problems, like VRPTW. We present the constraint-aware policy optimization (CPO) for VRPTWthat can let the agent learn the constraints as a representation of the whole environment to improve the generalization of RL methods. Extensive experiments on both the Solomon benchmark and the generated datasets demonstrate that our approach significantly outperforms other competition methods.

Nowadays, traffic congestion has become a serious problem that plagues the development of many cities aroundthe world and the travel and life of urban residents. Compared with the costly and long implementation cyclemeasures such as the promotion of public transportation construction, vehicle restriction, road reconstruction, etc., traffic prediction is the lowest cost and best means to solve traffic congestion. Relevant departmentscan give early warnings on congested road sections based on the results of traffic prediction, rationalize thedistribution of police forces, and solve the traffic congestion problem. At the same time, due to the increasingreal-time requirements of current traffic prediction, short-term traffic prediction has become a subject of widespread concern and research. Currently, the most widely used model for short-term traffic prediction are deeplearning models. This survey studied the relevant literature on the use of deep learning models to solve shortterm traffic prediction problem in the top journals of transportation in recent years, summarized the currentcommonly used traffic datasets, the mainstream deep learning models and their applications in this field. Finally, the challenges and future development trends of deep learning models applied in this field are discussed.

Background: The Mindful Attention Awareness Scale (MAAS) is widely used as an evaluation tool for mindfulness. Objectives: The present study aimed to validate the Persian version of the MAAS in Iranian substance abusers. Methods: This descriptive-analytical, cross-sectional study was conducted in Tehran during April 2017-December 2018 on 753 male Iranian substance abusers. Data were collected using a demographic questionnaire, the Persian version of the MAAS, the Depression, Anxiety, and Stress Scale-21 (DASS-21), the General Self-efficacy Scale, the Aggression Scale, and the Quality of Mindfulness Scale. The study had two stages of exploratory factor analysis and confirmatory factor analysis (CFA). Data analysis was performed in SPSS version 22, and a single-factor structure was employed to analyze the internal consistency of the MAAS in LISREL version 8.8. Results: The CFA results indicated that the single-factor model had a good fit to the data. In addition, negative correlations were observed between the MAAS, DASS-21, and aggression, while a positive correlation was denoted with self-efficacy (P < 0.01). Conclusions: According to the results, the Persian version of the MAAS is a valid and reliable instrument for assessing the mindfulness of Iranian substance abusers. Our findings shed light on a new direction for future focus and exploration in this regard.

Para avaliar o efeito do volume de tubetes no crescimento de mudas de Myracrodruon urundeuva, foi conduzido em delineamento inteiramente casualizado dois experimentos: Experimento 1, condução das mudas no viveiro e Experimento 2, avaliação pós-plantio simulando uma condição de campo, em função da idade das mudas. No Experimento 1, utilizaram-se três volumes de tubetes (55, 180 e 280 cm³) e quatro períodos de permanência das mudas no viveiro (60, 75, 90 e 105 dias após o semeio), sendo avaliadas quanto à altura, diâmetro, massa seca da parte aérea e massa seca do sistema radicular. No Experimento 2, mudas com 60, 75, 90 e 105 dias foram transferidas para sacolas 15.600 cm³ preenchidas com solo da área de plantio e avaliadas dois meses e meio após o plantio, quanto à altura e ao diâmetro.  As mudas produzidas nos recipientes de volume de 280 cm3 obtiveram melhor desenvolvimento em todos os atributos avaliados tanto na fase de viveiro como na fase campo. Assim, recomenda-se o uso dos tubetes de 280 cm³ para a produção de mudas de Myracrodruon urundeuva, devido à possibilidade da redução do ciclo de produção na fase de viveiro e melhor desempenho no campo.

Os ensaios de progênies constituem estratégias de conservação genética ex situ e também de melhoramento genético, pois permitem selecionar genótipos de melhor qualidade e elevada produtividade. No entanto, o melhoramento genético florestal não tem sido devidamente aplicado para espécies nativas da região Amazônica. O objetivo deste trabalho foi investigar se progênies de Parkia multijuga possuem desempenho silvicultural diferenciado e se é possível agrupá-las em diferentes classes de desempenho. O experimento foi instalado no delineamento de blocos casualizados com 14 progênies, sendo, ao total,18 mudas por cada progênie plantadas em seis blocos (252 plantas). Três anos após o plantio foram avaliados os caracteres: diâmetro à altura do peito (DAP), altura total, altura do fuste, diâmetro da copa, comprimento da copa, área de copa, proporção de copa, grau de esbeltez (GE), índice de abrangência (IA), índice de saliência (IS), ocorrência de bifurcação, percentual de indivíduos com fuste retilíneo e o estado fitossanitário. Foram também calculados: a sobrevivência, o incremento médio anual em altura e diâmetro e o índice de resposta integrada (IRI = sobrevivência e incrementos). O IRI variou cerca de três vezes entre a melhor e a pior progênie, da qual as progênies 7, 6, 11 e 10 tiveram os maiores valores de IRI. Uma análise de componentes principais com as características silviculturais de maior interesse (IRI, DAP, GE, fuste retilíneo, bifurcação e estado fitossanitário) permitiu agrupar as progênies 6, 7 e 11 entre aquelas com melhor desempenho silvicultural. A maior parte das progênies apresentou desempenho intermediário e semelhante entre si, sendo o pior desempenho para a maioria das características relacionado à progênie 2. Progênies de Parkia multijuga divergem quanto ao desempenho silvicultural durante o estabelecimento inicial dos plantios. Logo, o agrupamento das progênies com melhores desempenhos é fundamental na seleção de materiais genéticos superiores para a composição de plantios de produção desta espécie na região Amazônica.
