Pattern, Characterization and Quantification of Unauthorized Waste Dump Sites: A Case Study of Bangalore

Developing country municipal solid waste management is complex, managed by multiple institutions, prone to socio-political disruptions and often requires frequent and rapid estimates of good functioning. Estimating the quantity, composition and status of municipal solid waste found at unauthorized dump sites helps in diagnosis and in improving solid waste management system. The objective of this study was to find occurrences of unauthorized dump sites and to determine quantity, area, height of dumps, waste density and waste composition at these sites. A total of 452 locations were identified and quantification of solid wastes was carried out at 268 locations by determining waste spread area, measuring dump height and density by multiple techniques. Mixed dumped wastes at site was physically segregated into twelve waste categories (organic fraction, plastic, construction debris, paper, cloth, glass, leather, metal, rubber, biomedical waste, burnt waste and industrial wastes). It was estimated about 213310 Mg of wastes were dumped in 452 unauthorized dump sites. The composition of waste dumped in unauthorized sites have 41.3% of construction debris followed by 28.9% of organic waste and other fractions constituted the remaining. The waste composition at dump site suggests less efficient recycling systems and the possible direction for the system improvements.

Combinatorial parametrised spectra

We obtain combinatorial model categories of parametrised spectra, together with systems of base change Quillen adjunctions associated to maps of parameter spaces. We work with simplicial objects and use Hovey's sequential and symmetric stabilisation machines. By means of a Grothendieck construction for model categories, we produce combinatorial model categories controlling the totality of parametrised stable homotopy theory. The global model category of parametrised symmetric spectra is equipped with a symmetric monoidal model structure (the external smash product) inducing pairings in twisted cohomology groups. As an application of our results we prove a tangent prolongation of Simpson's theorem, characterising tangent $\infty$-categories of presentable $\infty$-categories as accessible localisations of $\infty$-categories of presheaves of parametrised spectra. Applying these results to the homotopy theory of smooth $\infty$-stacks produces well-behaved (symmetric monoidal) model categories of smooth parametrised spectra. These models provide a concrete foundation for studying twisted differential cohomology, incorporating previous work of Bunke and Nikolaus.

Industrial workwear for hot workplace environments: thermal management attributes.

Personal protective clothing (PPC) is critical for worker safety and wellbeing from both protection and thermal management perspectives, particularly as PPC typically covers more than 90% of the body. Research of PPC in low-risk categories such as mining, oil, gas, and construction and their thermal management attributes is limited, although these industries represent a significant proportion of the industrial workforce, work across a broad range of major industries, and frequently work in hot and/or humid thermal environments. This study evaluated and characterized the thermal management attributes of a selection of commercial low-level risk PPC ensembles currently used around the world as well as a civilian/corporate wear ensemble, using a sweating thermal manikin. The results demonstrate that there are substantially poorer thermal attributes for the PPC ensembles. Predicted Heat Strain Index (PHS) results for hot conditions reveal significantly lower duration limited exposure (DLE) and considerably greater body water loss for the wearers of PPC. Opportunities to substantially reduce PPC material mass and improve construction for these low-level risk categories in order to enhance thermal management performance are identified. Relationships between the thermal attributes of PPC and civilian clothing, and their garment construction, fit, and material characteristics are identified, providing new and important knowledge for current performance and direction for development of new improved PPC. This study provides researchers, developers, and garment designers with valuable insights for future improvement of PPC to create improved PPC for industrial workwear worn in hot environments.

Derived gluing construction of chiral algebras

We discuss the gluing construction of class $\mathcal{S}$ chiral algebras in derived setting. The gluing construction in non-derived setting was introduced by Arakawa to construct a family of vertex algebras of which the associated varieties give genus zero Moore-Tachikawa symplectic varieties. Motivated by the higher genus case, we introduce a dg vertex algebra version $\mathsf{MT}_{\mathrm{ch}}$ of the category of Moore-Tachikawa symplectic varieties, where a morphism is given by a dg vertex algebra equipped with action of the universal affine vertex algebra, and composition of morphisms is given by the BRST reduction. We also show that the procedure taking the associated scheme of gives a functor from $\mathsf{MT}_{\mathrm{ch}}$ to the category $\mathsf{MT}$ of derived Moore-Tachikawa varieties, which would imply compatibility of gluing constructions in both categories.

La regulación de los obstáculos epistemológicos en el aprendizaje de la evolución

Los obstáculos epistemológicos son modos de razonar que influyen en el aprendizaje de las ciencias. El trabajo didáctico sobre ellos implica el desarrollo de una vigilancia metacognitiva de manera de prestarles atención cada vez que se construye o se utiliza un modelo científico. En este trabajo caracterizaremos los modos de regulación de los obstáculos que surgieron durante el desarrollo de una secuencia didáctica para enseñar evolución en tres cursos de nivel medio. En particular propondremos ejemplos de la regulación de la teleología, uno de los obstáculos más importantes para la enseñanza de la biología. A partir de la construcción de categorías en base a la teoría fundamentada distinguimos tres modos de regular: un señalamiento del obstáculo en explicaciones de los estudiantes, una regulación de tipo individual compleja y una regulación de tipo social compleja.

Ethnography of the socio-sanitary reception in Rome. How are HIV/AIDS and hepatitis b involved in creating the construction of legal categories assigned to migrants?

PurposeThis paper aims to investigate the role that Italian third sector organizations have in the process of social and administrative categorization of newly arrived migrants living with human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/Aids) or hepatitis b. In Italy, free access to health is provided to all migrants and residence permits for medical treatment is granted for migrants living with a “serious illness” since the 1990s. The case of HIV/Aids and hepatitis b shows how this political openness, however, clashes with the tightening of migration policies.Design/methodology/approachThe study is based on ethnographic research conducted between 2014 and 2016 within an associative centre that deals with the socio-health care of newly arrived migrants in Rome. In addition to the participant observations, the study is based in semi-structured interviews conducted with 10 health-care providers (nurses, health-care assistants and socio-cultural mediators) and doctors and with 22 migrants coming from Sub-Saharan Africa and living with HIV/AIDS (10) and hepatitis b (12).FindingsIn Italy, the two infections have been identified as top diseases among migrant populations in the country but if HIV/Aids is always considered as a “serious illness”, hepatitis b is considered as a public health priority only in the case of a treatment prescription. These aspects have an important impact on the interactions between medical and social professionals and migrants affected by HIV/AIDS and hepatitis b, contributing differently to the creation of legal categories assigned to migrants.Originality/valueThe case of HIV/Aids and hepatitis b shows how the political openness of the public health system, clashes with the tightening of migration policies and analyse the role of the third sector has in this issue.

Trauma e historia. Reflexiones desde la trastienda

Este artículo, que reflexiona sobre la trastienda de la labor de investigación, parte de la consideración de que la metodología de análisis no constituye una dimensión aislada y meramente técnica del trabajo del historiador sino que es el aspecto encargado de articular orgánicamente la empiria con los fundamentos ontológicos de la historia. Así, lo metodológico no se reduce al conjunto de procedimientos estandarizados y previstos para una investigación, sino que comprende un trabajo que refiere antes que nada a la construcción de categorías operativas que intervienen incluso en lo que se denomina definición de objeto. En las páginas que siguen, intento explorar los alcances de estos postulados en el caso del abordaje de la historia reciente y de los llamados pasados traumáticos.

Seven steps for qualitative treatment in health research: the Clinical-Qualitative Content Analysis.

Qualitative Health research procedures that are not always applied, mainly in the analysis phase. Our objective is to present a systematized technique of step-by-step procedures for qualitative content analysis in the health field: Clinical-Qualitative Content Analysis. Our proposal consider that the qualitative research applied to the field of health, can acquire a perspective analogous to clinical practice and aims to interpret meanings expressed in reports through individual interviews or statements. This analysis takes part of the Clinical-Qualitative Method. The literature review was realized through: a book chapter, eight original articles and three methodological articles. The Clinical-qualitative Content Analysis technique comprises seven steps: 1) Editing material for analysis; 2) Floating reading; 3) Construction of the units of analysis; 4) Construction of codes of meaning; 5) General refining of the codes and the Construction of categories; 6) Discussion; 7) Validity. The clinical-qualitative analysis presupposes and involves a critical reflection on the processes carried out at each step. This reflection is an extremely rich process, if carried out collectively and in dialogue with other researchers with some proficiency in qualitative methods.

Zooming?! - Higher Education Faculty Perspectives

Aim/Purpose: The COVID-19 pandemic demanded an immediate and massive adaptation of higher education to distance learning. Teachers had to transform from face-to-face to distance teaching, with insufficient pedagogical and technological knowledge and resources. This study aims to capture higher education faculty experiences in the very early stages of the crisis-prompted transition into synchronous distance education in order to obtain a broader view on the faculty’s perspectives (benefits, challenges and insights) on distance teaching through synchronous online environments. Background: Although online teaching and learning have been part of higher education teaching for more than two decades, many instructors found themselves teaching remotely for the first time and facing new and unpredicted challenges. Methodology: This study explored and analyzed an e-mail thread discourse between teachers in a higher education institute, two months after “going online” due to the COVID-19 pandemic. A singular case study was conducted, and a retrospective and snapshot case study approach was used. Data analysis was an iterative exploratory process of going back and forth the empirical material, resulting in the construction of categories, then themes, and finally a conceptual framework was developed. Contribution: The findings contribute the knowledge domain of implementation of immediate and massive online teaching and learning from the faculty perspective. Findings: Two main focal points, students and teachers, were encountered. Three main recurring themes were identified associated with both students and teachers: Convenience, Ethical Issues, and Insights for the future. Two themes were identified associated with faculty: Pedagogy and Tools, and Resources. In addition, two themes were identified for students: Attendance and Responses. Each of the themes was decomposed into several aspects. Recommendations for Practitioners: Higher education institutions and stakeholders should build a campus wide e-learning agenda including appropriate infrastructure and professional development for the future. Recommendations for Researchers: The study presented a conceptual model based on qualitative case study methodology. The impact and influence of each of the components of the model should be further researched and measured using quantitative methodologies. Impact on Society: Understanding the benefits and challenges of distance learning from the faculty perspectives in order to implement better distance learning strategies. Future Research: The impact and influence of each of the components of the model should be further researched and measured using quantitative methodologies.

Jealousy vs envy

Speakers of many languages tend to use pairs of words such as emotion/feeling or jealousy/envy interchangeably. This paper explores the differences in the way in which the emotional states of jealousy and envy are understood (in the Croa­tian language ljubomora and zavist) and the influence of culture on the expression of these states. First, we establish the cultural framework that significantly shapes the experience and expression of emotional states, and summarize cognitive aspects of the two emotions. Second, we demonstrate that Croatian 19th- and 20th- century belles lettres differentiate between the two in the way it is described in sciences. Third, a psycholinguistic questionnaire was used to investigate features of the conceptual content from 209 high school students. Finally, the results were compared with the empirical corpus analysis of the linguistic constructions of emotional categories. Complementary methods used in this research show indications of an ongoing semasiological change of ljubomora and zavist in a significant part of Croatian speakers.

An analysis of the intersections between race and class in representations of Black and white gay men in QueerLife

This article seeks to critically analyse how intersections of race and class shape representations of Black and white gay men in QueerLife, a South African online magazine. It focuses on QueerLife's '4men' section and how its content represents classed and raced gay identities. My argument is that QueerLife forwards racialised and classed representations of the gay lifestyle, which reinforce homonormalisation within what is known as the "Pink Economy". Using Critical Diversity Literacy (CDL) to read the underlying meanings in texts and images, the article concludes that QueerLife is complicit in the construction of gay identity categories that seek to appeal to urban, white, middle-class gay-identifying communities in South Africa. The article also demonstrates how, when Black bodies are represented in QueerLife, exceptionalism mediates their visibility in this online magazine. Overall, the findings demonstrate how Black and white gay bodies are mediated online and how their different racial visibilities are negotiated within the system of structural racism. Keywords: Class, gayness, Pink Economy, QueerLife, representation, racism.

Nexus between Total Quality Management Practices and Construction Firms’ Performance in Pakistan

Construction industry of any country plays a dynamic role in the prosperity and development of that country. It contributes more than any other industry in the economy growth and stability. Continual improvement firm performance can be measured through quality of work and services they provide to customers. However, for companies to compete with each other as well as in global markets they must need to adopt such techniques which are applied in the developed countries. One of the techniques is the application and evaluation of total quality management practices. As, this technique is already applied in other sectors such as manufacturing, services, health and development in the developed countries. So, this study and its findings are based on measuring the effects of total quality management practices i.e., organizational leadership, policy, and strategy, customer focus and process management on firm performance based on employee satisfaction and timely completion of projects. To check and measure the impact of TQM practices 100 construction companies were taken as sample/ These TQM practices were implemented on C-2 category construction companies of Khyber-Pakhtunkhwa, Pakistan registered with Pakistan Engineering Council. The findings of this study concluded that all the listed practices have direct and indirect effects on the enhancement of form’s performance.

A local criterion of fairness in sport: Comparing the property advantages of Caster Semenya and Eero Mäntyranta with implications for the construction of categories in sport.

This paper aims to bring a novel approach to the discussion of unfair advantages in sport by looking for a local criterion of fairness instead of a universal criterion. A local criterion of fairness would not solve the general dispute over what counts as an unfair advantage, but it would be beneficial in evaluating specific cases and could guide further discussion about them. We seek a local criterion of fairness by comparing the specific property advantages of Caster Semenya and Eero Mäntyranta. South African Semenya is a middle-distance runner whose right to compete in the female category has been challenged owing to her assumed difference of sex development and related high level of testosterone. Finnish Mäntyranta was a cross-country skier with an exceptionally high haematocrit level. We examine whether there is a relevant difference between their advantages that would justify treating the athletes differently. We propose that the criterion 'not attainable by other athletes in the same category' could stand as a local criterion of fairness under certain conditions. However, its proper application requires further discussion on how to justify categories in sport.

A Constructive Approach to Freyd Categories

We discuss Peter Freyd’s universal way of equipping an additive category mathbf {P} with cokernels from a constructive point of view. The so-called Freyd category mathcal {A}(mathbf {P}) is abelian if and only if mathbf {P} has weak kernels. Moreover, mathcal {A}(mathbf {P}) has decidable equality for morphisms if and only if we have an algorithm for solving linear systems X cdot alpha = beta for morphisms alpha and beta in mathbf {P}. We give an example of an additive category with weak kernels and decidable equality for morphisms in which the question whether such a linear system admits a solution is computationally undecidable. Furthermore, we discuss an additional computational structure for mathbf {P} that helps solving linear systems in mathbf {P} and even in the iterated Freyd category construction mathcal {A}( mathcal {A}(mathbf {P})^{mathrm {op}} ), which can be identified with the category of finitely presented covariant functors on mathcal {A}(mathbf {P}). The upshot of this paper is a constructive approach to finitely presented functors that subsumes and enhances the standard approach to finitely presented modules in computer algebra.

The construction of braided tensor categories from Hopf braces

ABSTRACT Let be a Hopf brace. We first show that the category of left compatible modules over is a tensor category. Next, we show that its Drinfeld centre is equivalent to the category of left Yetter–Drinfeld modules over as a braided tensor category. Finally, we show that Radford's biproduct and constitute a Hopf brace, where R is a Hopf algebra in . This presents some new method to construct Hopf braces.

Derivatives of normal functions in reverse mathematics

Consider a normal function f on the ordinals (i.e. a function f that is strictly increasing and continuous at limit stages). By enumerating the fixed points of f we obtain a faster normal function f′, called the derivative of f. The present paper investigates this important construction from the viewpoint of reverse mathematics. In this framework we must restrict our attention to normal functions f:ℵ1→ℵ1 that are represented by dilators (i.e. particularly uniform endofunctors on the category of well-orders, as introduced by J.-Y. Girard). Due to a categorical construction of P. Aczel, each normal dilator T has a derivative ∂T. We will give a new construction of the derivative, which shows that the existence and fundamental properties of ∂T can already be established in the theory RCA0. The latter does not prove, however, that ∂T preserves well-foundedness. Our main result shows that the statement “for every normal dilator T, its derivative ∂T preserves well-foundedness” is ACA0-provably equivalent to Π11-bar induction (and hence to Σ11-dependent choice and to Π21-reflection for ω-models).

Mobilizing collective hatred through humour: Affective-discursive production and reception of populist rhetoric.

This research examines the mobilization of populist rhetoric of the 2019 Finns Party election video. By focusing on both the FP’s election video (production) and Youtube users’ comments (reception), we examine the constructions and uses of social categories and humour as well as responses to their rhetorical deployment among like‐minded supporters and opponents. The multimodal analysis of the production of a populist campaign video demonstrates the construction of social categories and humour through the five steps of collective hate. These humorous messages are differently received by like‐minded and opposing YouTube users. Two supportive affective–discursive practices – glorification and schadenfreude – both express shared joy and laughter, but while glorification emphasizes the positive self‐understanding of the in‐group, schadenfreude belittles the ‘political Other’. Two opposing affective–discursive practices – irritation and scorn – place FP voters in subject positions of morally and intellectually inferior fascists, racists, and idiots. The populist message fosters expressions of social anger and polarization between FP supporters and opponents. Humour entangled with hatred encourages a sense of moral superiority in both groups. This study contributes to the current knowledge of mobilizing populist rhetoric and polarization, and responds to the call to broaden analysis of political communication in the field of multimodality.

Environmental Education to Change the Consumption Model and Curb Climate Change

Environmental education plays a fundamental role in the fight against climate change and the transformation towards a more sustainable and environmentally friendly socio-economic model. This study shows how to evaluate the effectiveness of a program for compulsory education students in Spain. The subject of the program focused on the effects of climate change in relation to our consumption model and the generation of waste. A mixed research methodology is proposed that combines a quantitative (10 items on the Likert scale, n = 714) and qualitative approach (category construction and analysis on open-ended questions). A study of the reliability and validity of the measure was carried out through a categorical principal component analysis (CATPCA). The multivariate analysis of variance (MANOVA) correlates the gender and educational level of the students to the learning acquired in the program. For example, the results show how students are convinced that adopting minimal pro-environmental habits (turning off lights and unplugging electronics, choosing public transport to get around, or using solar and wind power to produce electricity) can help mitigate climate change. The conclusions show the difficulties and challenges of education for responsible consumption, emphasizing the development of environmental education programs for reducing the effects of climate change.

Unsettling international law and peace-making: An encounter with queer theory

AbstractThis article examines the usefulness of an encounter with queer theory to contribute to the peaceful resolution of armed conflicts, to question the traditional frontiers of international law, and to lay the groundwork for envisaging different forms of peace and peace-making. In a field where, arguably, little genuine progress has been made to resolve armed conflicts and to address underlying forms of violence, queer theory can reinforce a pluralistic understanding of law and suggest much-needed unsettling and creative approaches. The article focuses on queer theory’s specific critique of the construction and normalization of hierarchies, categories, and identities, which almost always – whether explicitly or implicitly – lie at the heart of armed conflicts and frame peace negotiations, without ever being truly reconsidered. Moreover, queer theory allows appreciating both peace and law beyond predetermined categorizations and as aspirational endeavours that are constantly evolving. Through a dialogue between two figures, which imagines what Peace and qt* might want to tell each other, this article also attempts to queer the standard academic format and to question the dominant forms of expression and knowledge-production in academia.
