Automated waste-sorting and recycling classification using artificial neural network and features fusion: a digital-enabled circular economy vision for smart cities.

Waste generation in smart cities is a critical issue, and the interim steps towards its management were not that effective. But at present, the challenge of meeting recycling requirements due to the practical difficulty involved in waste sorting decelerates smart city CE vision. In this paper, a digital model that automatically sorts the generated waste and classifies the type of waste as per the recycling requirements based on an artificial neural network (ANN) and features fusion techniques is proposed. In the proposed model, various features extracted using image processing are combined to develop a sophisticated classifier. Based on the different features, different models are built, and each model produces a single decision. Besides, the kind of class is determined using machine learning. The model is validated by extracting relevant information from the dataset containing 2400 images of possible waste types recycled across three categories. Based on the analysis, it is observed that the proposed model achieved an accuracy of 91.7%, proving its ability to sort and classify the waste as per the recycling requirements automatically. Overall, this analysis suggests that a digital-enabled CE vision could improve the waste sorting services and recycling decisions across the value chain in smart cities.

Racial composition and trajectories of gentrification in the United States

Prior studies suggest that middle-income Americans are more likely to move to predominately white, low-income neighbourhoods than predominately black or Latino neighbourhoods. Given that black and Latino neighbourhoods are, on average, lower income and higher in poverty than low-income, white neighbourhoods, it may be that gentrification in these neighbourhoods is a different kind of change than that occurring in predominately white neighbourhoods. Using Census data from 1970 to 2010 for 275 Metropolitan Statistical Areas, I find that racial composition influences not only whether gentrification occurs, but how it occurs and whether it influences racial demographics. Majority white gentrifying tracts were more likely to experience an increase in higher-income residents and white residents, while majority non-white gentrifying tracts experienced an increase in higher-educated but not higher-income residents, and an increase in white residents and decrease in black and Latino residents. Racial composition thus contributed to the kind of gentrification that a tract experienced and the extent to which gentrification produced racial change. These findings suggest that race affects not only where gentrification occurs, as previously established, but also the kind of class and racial changes a neighbourhood experiences. Ultimately, this article suggests that gentrification neither unfolds in one way nor affects all neighbourhoods the same way.

A New Class Weighted Algorithm for PSVM

Focusing on the problem of slow training speed existing in the SVM in intrusion detection, this paper improves the faster PSVM (Proximal SVM) method and proposes a new kind of class - weighted PSVM algorithm. This kind of algorithm not only has a fast classification speed, but also improves the classification accuracy.

Effect of Mindfulness on Empathy and Self-Compassion: An Adapted MBCT Program on Filipino College Students.

Attending college is meaningful for many young adults. This period is marked by physical, emotional, and psychological changes that can have both positive and negative effects on college students. The last two decades have seen an alarming increase in the number of college students who suffer from mental health conditions, such as depression, suicide, anxiety, and alcohol abuse. It is recommended that actions to support the students’ wellbeing must be creative and evidence-based. Research suggests that a mindfulness-based intervention may be an effective strategy to address mental health conditions among college students. This study was done to examine the efficacy of an adapted mindfulness-based cognitive therapy (MBCT) program that was implemented in a classroom setting in the Philippines and to explore how mindfulness practice can affect empathy and self-compassion on senior Filipino college students aged 19–22 years old. Two classes were used to compare the effects of mindfulness intervention. One class underwent the adapted MBCT program while the other class underwent the same kind of class without mindfulness interventions. Self-report measures of the Five Facet Mindfulness Questionnaire, Perspective Taking subscale and Empathic Concern subscale of Interpersonal Reactivity Index, and Self-compassion scale—short form were administered before undergoing the adapted MBCT and after the program. After going through the adapted MBCT, college students’ mindfulness significantly improved. Empathy and self-compassion also significantly improved after undergoing the program. This corroborates previous studies done on mindfulness and its efficacy with adolescents and suggests how practicing mindfulness can improve empathy and self-compassion with Filipino college students. It provides a promising groundwork for the emerging interest and research in Asia, particularly in the Philippines, on how the practice of mindfulness can help with the mental health of college students.

Teachers’ and Students’ Perceptions of Virtual Classes and the Effectiveness of Virtual Classes in Enhancing Communication Skills

The use of the Internet is increasing the possibilities for language learning and teaching (Sallbego & Tumolo, 2015). Virtual classes use computer-mediated technology to facilitate learning, teaching, and communication processes. The purpose of this study is to investigate teachers’ and students’ perceptions of English as a foreign language (EFL) virtual classes. Moreover, it also aims to highlight the effect of this kind of class on enhancing communication skills. Therefore, the main research question is about the perceptions that students and teachers have of EFL virtual classes. This study conducted in the Female English Department at King Khalid University in Abha. The participants were thirty teachers and students who were divided into two equal groups (fifteen in each group). Regarding that, participants answered a particular questionnaire. The results show that the majority of the students and teachers possess positive attitudes toward teaching and learning through EFL virtual classes. Moreover, they also agree with the significant role of virtual courses in enhancing communication skills. Thus, implementing EFL virtual classes can be recommended as beneficial. This study states some recommendations in light of its findings.

Aulas com interação: ensinando (e aprendendo) língua portuguesa e cultura brasileira na Coreia do Sul

According to the Korean students' own perspective, what is the greatest difficulty in learning Portuguese” and “what kind of class is best to learn Portuguese”? This article analyzes these two important aspects of the profile of students who are learning Brazilian Portuguese as a foreign language at Hankuk, one of South Korea's most prestigious universities in Foreign Studies field. Based on collection of some data considered relevant for the acquisition process of a foreign language, we aim at reflecting on these aspects to contribute to the improvement of the teaching-learning process of Brazilian Portuguese as a foreign language and Brazilian culture to Korean students. The results indicate that grammatical aspects are perceived by Korean students as the major obstacle to the development of their proficiency and that, on the other hand, Communicative Teaching meets the expectation of Korean students for a class that leads them to take ownership of their own learning process as protagonists.

Zeolite P synthesis based on fly ash and its removal of Cu(II) and Ni(II) ions

Zeolite P was synthesized through hydrothermal method based on a kind of Class C fly ash (FA). X-ray diffraction (XRD), scanning electron microscopy (SEM), and Brunauer–Emmett–Teller (BET) were used to analyze and characterize the synthetic sample. The kinetics and thermodynamics of copper and nickel ions removed by the zeolite samples were experimentally explored in detail. The results of kinetic treatment showed the second-order exchange second-order saturation model (SESSM) can well describe the removal process of copper ions, while the first-order empirical kinetic model (FEKM) is the best kinetic model for nickel ions. Langmuir and Freundlich isotherms were used to fit the equilibrium concentration of Cu(II) or Ni(II) under certain conditions. Whether for copper or nickel ion, the Langmuir model is in good agreement with the experimental equilibrium concentration. The apparent theoretical removal capacities for Cu(II) and Ni(II) can reach to 138.1 mg·g− 1 and 77.0 mg·g− 1, respectively.

The Model Construction of English Ecological Class in the High School in China

The Ecological class is a kind of class in which the system of class teaching is in a state of dynamic balance and it can enhance the efficiency of class teaching. The article analyzes the feature of English ecological class，illustrates the non-ecological class teaching problems and explores the ways to establish English ecological class from the five aspects such as: teaching environment, the relationship between the teacher and students and the relationship between students and students, teaching methods, teaching content, and teaching evaluation, so as to improve the English teaching effect of the high school, and to provide some reference for the English teaching in the high school.

CONSIDERABLE STRATEGIES OF TEACHING LARGE MULTI-LEVEL CLASSES: A NARRATIVE STUDY OF WHAT EFL TEACHERS SHOULD DO

Teaching classes in which there is a uniformity of learners‟ proficiency level is the most ideal environment in language classes since it enables teachers to apply appropriate teaching and learning strategies based on the individual student‟s level. However, in EFL settings, most teachers especially in school environments have to teach classes in which the learners have multiple levels of ability, since at schools, there is no placement test on students‟ ability of English as is usually done in private language institutions. This paper provides some useful strategies which can be applied by teachers in teaching classes where true and false beginners are within the same class. Applying these strategies is expected to assist weaker students to get benefit from interacting with stronger students without holding back the strong ones. Teaching English in the EFL context needs more efforts and persistence since the target language (TL) is not used in the daily conversation. In addition, it is common to find large and mixed- ability students in the EFL contexts, which management is surely not easy. Consequently, EFL teachers often find both true and false beginners in a classroom. According to Brown (2007) true beginners are students who do not have any knowledge of the target language, whereas false beginners are those who have previously studied the target language ( they have been familiar with alphabets, simple greetings, etc), but they remember only a little of what they have learned. Due to the characteristics of beginners who still have a high dependency on their teachers as a role model , the most suitable approach to be applied in this kind of class is the teacher-centered classroom (Brown, 2007). Therefore, in this novice stage, teachers play a significant role in helping the lower level students to improve their language skills. Since there are two levels of beginners in this kind of class, a good language teacher should apply some special techniques to successfully teach this mixed-ability class as teaching this kind of class needs more preparation berita terkini terbaru and special techniques than teaching in placed or streamed classes .I am going to provide some strategies which can be applied in teaching true and false beginners within a class.

Rethinking ‘IT/IS use in a technological mature society’ from the actuality point of view: critical learning in reflection on SSM meeting about ‘IT/IS use’

The history of the human-centered system movement (Gill in AI Soc 10(2), 1996) tells us that information technology (referred to as IT below) has come to dominate our life-world or societal functions. Since from 1990s, its streaming influence could be called ‘abnormal.’ Since entering the twenty-first century, the IT system has been on automatic acceleration and has been spreading more and more rapidly to many facets of our lives. In many sectors, this ubiquitous streaming of IT is seen to be central to societal development, and in a Japanese sense, IT could be seen as a resource to realizing technologically a mature society. This trend of IT seems to be unstoppable. In this sense, IT dominance can be regarded as abnormal to the point that IT-centered information systems (referred to as IS below) fall far short of the deep appreciation of the complex and diverse life needs of people and societies, and this leads to the implementation of IT/IS from technological perspective, with a belief that everything, which we can do could be and should be, done now by IT/IS. However, as IT/IS have become to be embedded in many facets of societies and are influencing over our everyday life, we need to examine them not from the point of ‘capability’ but ‘allowability,’ in other words, not from the perspective of technology (cognition), but from the prospective of intuition and feeling of actual life (action). We term reality as seen in the narrow sense of cognition and actuality as seen in terms of action (Uchiyama in Theory and practice of actuality, Daito Bunka University, Tokyo, 2003). We draw a distinction between the two classes of ‘IT/IS’ systems, those which belong to the ‘reality’ and those which belong to the ‘actuality.’ To appreciate this distinction, we propose that this requires not only an understanding of the design of these IT systems but of the methodology of their use and their evaluation. To carry out the process of evaluation of IT/IS systems, we need to develop a new ‘appreciation’ methodology which enables us to rethink ‘IT/IS’ as ‘A system to use IT/IS.’ This idea is similar to the idea of Beck’s (World risk society theory (trans: Shimamura K), Chikuma Scholastic Collection (in Japanese), 2010) reflecting the modern. So, we propose a strict distinction between the two systems classes of ‘IT/IS’ which we call belonging to the ‘reality’ and ‘A system to use IT/IS’ which we call belonging to the ‘actuality.’ The methodology to deal with ‘actuality’ has not yet been developed, but Checkland and Poulter’s (Learning for action, Wiley, New York, 2006) soft systems methodology (referred to as SSM below) intends to deal with this kind of class of systems, that is, ‘human activity systems.’ He uses the key concept of ‘accommodation’ which means ‘to live with different individual world views based on sharing of actuality,’ and thus, he proposes to overcome the idea of consensus which is the agreement with the ‘reality’ level. In this paper, we adopt a methodology based on the SSM’s accommodation and not based on the consensus on the ‘reality’ level. By using such a methodological thinking, we reconsider the problem of evolving technologically a mature society which can be seen as a problem relevant to ‘A system using IT/IS’ rather than the problem of IT/IS itself. In doing so, we could draw some innovative orientations in the field of IT/IS which by traditional methodology could not be drawn. It is not certain whether our attempt could make a difference to the runaway of IT/IS. We illustrate this purpose by studying a workshop process which highlights that even participating experts of IT/IS themselves felt apprehensive about the more and more focus on the implementation of IT/IS solutions both in the present and the future. We believe that the first step toward this purpose is to explore the new orientation of IT/IS use. The aim of this first step is to make a difference to the ‘abnormal’ situation and hope to create a foothold for the reorientation of ‘A system to use IT/IS.’

Assessing cultural awareness and linguistic competency of EFL learners in a CMC-based active learning context

Abstract Most studies examining Computer Mediated Communication to enhance EFL learning have been limited to evaluating test scores, questionnaires, and interviewing students. This study used a holistic assessment model with qualitative analysis of student reflective essays and descriptive analysis of pre- and post-test oral performance by students in a university English conversation course in Taiwan. The instructional design included Internet videoconferences with a native speaker in the United States and an emphasis on critical thinking about cultural differences and similarities. Although the class was too small for statistical analysis, the students' oral scores improved an average of 44.5% from the beginning to end of the semester. The analysis of the essays showed that students engaged in reflective thinking about 70% of the items they observed in their essays, which is evidence of critical thinking. Qualitative analysis revealed four major recurring themes in the students' essays, 1) this was a different kind of class from any they have taken before and the instructional design was helpful, 2) the importance of history and underlying meaning of iconic cultural elements, such as holidays and festivals, 3) their development of a growing multicultural worldview, and 4) their growing confidence as a result of the course.

Linking Students with Community in Collaborative Governance: A Report on a Service-Learning Class

Collaborative governance is increasingly becoming a topic for scholarly research and practitioner skill development as well as a component of graduate programs in public administration. This article documents a service-learning project in a graduate-level Masters in Public Administration class on cross-sector governance. The article begins with a brief review of literature on university-community relations and, specifically, the civic mission of institutions of higher education and the role of service learning in public administration programs. The teaching case is then introduced, with the full context and detail explained. Lessons are offered for replicating this kind of class. An analysis of the success of the case is offered based on reflection journals written by students throughout the semester.

"A dream for me": Idioms of progress among Peruvian migrants in Madrid

In this article, I examine idioms of progress among Peruvian migrants in Madrid, Spain. Since the first waves of migration from Peru in the 1980s, Spain has represented for many Peruvians the possibility of realizing aspirations to socioeconomic betterment. Open-ended interviews and participant observation with Peruvians living in Madrid highlighted the importance of superación (overcoming, surmounting) in contextualizing migrants’ desires for socioeconomic improvement. As an ideology of individual and collective progress intimately tied to Peruvian histories of violence, superación promises to benefit migrants’ communities and overcome entrenched racial hierarchies that associate indigeneity with poverty. In Madrid, I observed that desires for superación among Peruvian migrants often buttressed a moral conduct toward their family, region, and nation. I discuss the ways by which gender and nationality become important lines of difference as migrants negotiate their own conceptions of progress in the face of Spain’s decadent modernity and hostile racism. Lastly, I investigate the relationship between superación and another powerful narrative of progress in Spain: consumerism. Analyzing an excursion through a Madrid IKEA with Peruvian migrants, I suggest that consumerism’s discourses of universalized access are in fact implicated in the same kind of class and racial exclusions that subtend superación. I conclude by pointing toward the myriad narratives and subjects of progress at play in transnational settings, and suggest that rather than subscribe to models of migrant assimilation, attention must be paid to the local contexts and articulations of progress by which migrants strive for better lives.

Research of necessary rules influence on classifying

The computing gist of algorithms based on rules involves the rules like " A→C " and their confidences.Here," A " represents the set of decision attributes and their values,and " C " represents a kind of class label.Can the rules like " C→A " act positively in classifying algorithms? A simple experiment was designed,which considered the associations between single attribute values and class label.Two testing methods were made according to the experiment goals.By the first method,confidences of " A→C " were used.By the second method,the confidences of both " A→C " and " C→A " were used.The experiments were made on several typical classifying data sets.The results show the higher classifying precision by using the double confidences.

DYADIC THEORETICAL GAMES MODELS OF DECISION-MAKING FOR THE LEXICOGRAPHIC VECTOR PAYOFFS

This article is about the full analysis of one concrete class of general non-cooperative lexicographic games and its computer programming. In such game, the payoffs of players are lexicographic vector payoffs — m scalar criteria vectors. At the same time, these criteria are strictly ranked on the set of the situations with lexicographic preference. In some such kind of game a Nash's equilibrium may not exist. In the given article the full analysis of one class of dyadic lexicographic games is worked out. Such kind of class is the non-cooperative lexicographic games, where each player has got two pure strategies and the payoff of each player solely depends on the strategies of two players in each situation. Therefore, the player's payoffs are given by 2 × 2 matrices, the elements of which are lexicographic utilities.

On the Impossibility of (Some) Critical Pedagogies: Critical Positionalities within a Binary

In teaching, our teacherly bodies are always available for the interpretation and evaluation of others. Indeed, it was a first lesson for many: entering the classroom the first time and feeling those eyes reading your performance of self, deciding what kind of class (and what kind of teacher) this experience was going to offer. However, our students' reading are never theirs alone— they are produced and made possible by larger ideological struggles that produce the possibilities and impossibilities of what they (and we) can conceive. These struggles, these systemic reiterated forms work to generate binaries that often deny the complicated identities that occupy our shared spaces. In this article, we chart out and enflesh the teacher's body, asking about the invisible bodies that these binaries exclude. In particular, we ask about sexualized bodies and the binaries that erase real opportunity for critically informed democratic pedagogy.

In Malone's hagiography, Sinatra's music is inseparable from his image, both setting the standard for stylish virility. His tough Jersey accent redefined the American language, Malone writes, plus he used his voice-not gun-and made the girlies stick out them tits like it was holdup!

The internationalisation of business and domestic class compromises: A four country study

This article examines the impact of international business on the kind of class compromises that evolved and characterised many West European societies until the late 1970s. It raises the question of why class compromises endured longer in Austria and Sweden than in Belgium and the Netherlands. The argument is that domestic business in Austria and Sweden has fewer alliances with international capital and is, therefore, in a sense less integrated in world markets than those in Belgium and the Netherlands. The conclusion of the article, based upon recent trends, points out that the differences between the four countries appear to be rapidly disappearing.
