Hybrid vector similarity measures based on complex hesitant fuzzy sets and their applications to pattern recognition and medical diagnosis
Authors: Mahmood Tahir , Ur Rehman Ubaid , Ali Zeeshan , Mahmood Tariq
Published: July 2020

Fuzzy set (FS) theory is one of the most important tool to deasl with complicated and difficult information in real-world. Now FS has many extensions and hesitant fuzzy set (HFS) is one of them. Further generalization of FS is complex fuzzy set (CFS), which contains only the membership grade, whose range is unit disc instead of [0, 1]. The aim of this paper is to present the idea of complex hesitant fuzzy set (CHFS) and to introduce its basic properties. Basically, CHFS is the combination of CFS and HFS to deal with two dimension information in a single set. Further, the vector similarity measures (VSMs) such as Jaccard similarity measures (JSMs), Dice similarity measures (DSMs) and Cosine similarity measures (CSMs) for CHFSs are discussed. The special cases of the proposed measures are also discussed. Then, the notion of complex hesitant fuzzy hybrid vector similarity measures are utilized in the environment of pattern recognition and medical diagnosis. Further, based on these distance measures, a decision-making method has been presented for finding the best alternative under the set of the feasible one. Illustrative examples from the field of pattern recognition as well as medical diagnosis have been taken to validate the approach. Finally, the comparison between proposed approaches with existing approaches are also discussed to find the reliability and proficiency of the elaborated measures for complex hesitant fuzzy elements.

Collecting data from businesses faces ever-larger challenges, some of them calling for an overhaul of underlying methodology, e.g. motivation for participating is low; technology is shaping data collection processes; response processes within businesses are imperfectly understood while alternative data sources originating from digitalization processes push the response process (thus also response quality) further out of our sight. The paper reviews these challenges, discusses them in light of new developments in the field, and proposes directions for future research. This review may help those that collect data from businesses (e.g. national statistical institutes, academia, and private statistical agencies) to reconsider their current approaches in light of what promises to work (or not) in today’s environment and to build their toolkit of business data collection methods.
Sharing data on the activities of multinational enterprise groups: Innovations to redesign statistical practices and processes
Authors: Koskimäki Timo , Peltola Rami
Published: July 2020

The professional discussion on “The future of economic statistics” has a practical driver: Economic statistics, produced by national statistical offices, face severe difficulties in describing the national and global economic development in a relevant and coherent manner. This is not only our perception as statisticians – there is a growing criticism towards traditional economic statistics among researchers, policymakers and other users. In this article, we reflect on the factors that have caused the current situation and propose solutions to improving the situation by data sharing. One aspect of the solution relates to the role of national statistical offices. Instead of being solely national institutions, dealing with national data only, they should exploit the possibilities of using statistical data, collected by statistical authorities of other countries, to produce better quality economic statistics. The other aspect of the solution is the sharing of innovative practices to understand and correctly record the activities of multinational enterprise groups (MNEs). The proposals we make in this article are not restricted to MNEs but are applicable to any type of economic activity with a cross-border dimension. The observations we make here are based on the work done when preparing the UNECE Guide to Sharing Economic Data.
A vision on future advanced data collection
Authors: Salemink Irene , Dufour Stéphane , van der Steen Marcel
Published: July 2020

Society’s demand for data-driven, fact-based information continues to increase. National statistical offices play a critical role in providing this demand-driven information to support evidence-based policy making. Thereby transforming from suppliers of official statistics to providers of trusted smart statistics. The digital transformation, data revolution and emergence of “big data” all influence the way NSOs collect data. Data are everywhere, generated by everything and everyone being stored in numerous locations and devices. The nature of data collection is bound to change. Using solely primary data collection would be too time-consuming, costly and burdensome to satisfy the increasing demand. NSOs should aim to use the vast amounts of data available in our digital society to be used as inputs for new statistical products, to supplement existing data acquisition or as replacements for existing survey inputs. Many areas must be taken into account including new data sources, collection methods and collection process redesigns. This comes with consequences with respect to methodology, technology, quality, metadata and standards, confidentiality, privacy etc. Knowledge development requires collaboration between NSOs, governments, end users, academic institutions, research organizations and private sector companies. Social acceptability needs to increase to maximize the benefit of these data sources to produce smart statistics.
The role of inter-household transfers in mitigating the impact of economic shocks on income distribution in Indonesia
Authors: Winardi Wisnu
Published: July 2020

COVID-19 outbreak has triggered many economic shocks globally. In this study we estimate the role of inter-households transfer in mitigating the impacts of the outbreak on Indonesian economy using a CGE model. The result shows that commodity prices and enactment of physical distancing measures bring negative impacts on the economy. Government response by lowering direct tax rates and increasing transfer to households could not fully compensate the impacts but enlighten it slightly. Households response by increasing inter-household transfers helps the government policy, particularly in reducing the decrease of households’ income and consumption. The result indicates that inter-household transfer could be regarded as an effective instrument to improve the household income distribution quality and reduce the poverty. Regarding that, stakeholders in the economy should improve the collaborative policies to capitalize the policy instruments optimally. Furthermore, the result also indicates that household consumption is not a sustainable engine to boost the economic growth. Prioritizing consumption over saving in the long run could lead to inability of the economy to engage a self-financed investment.
A method for predicting the Actual Percentage of Dissatisfied (APD) through a simple proposition of thermal comfort zones in a working environment
Authors: Broday Evandro Eduardo , de Paula Xavier Antonio Augusto
Published: July 2020

BACKGROUND: Over the last few decades, there has been a concern to improve the quality of indoor work environments and increase energy efficiency as people spend much of their time in such settings. OBJECTIVE: This study analyzed a group of women developing sedentary activities to determine the Actual Percentage of Dissatisfied (APD) in the environment, considering that all people who voted any value other than zero on the seven-point scale are deemed dissatisfied. METHODS: After this analysis, using the probit regression model, hot and cold air temperature curves were plotted so as to determine in which situation the number of people dissatisfied with the environment is minimal. RESULTS: The results showed an APD of 52.31%, which is different from the ADP recommended by ISO 7730 (2005) [–0.5 < PMV < + 0.5, PPD < 10% ]. The probit analysis using the cut of 10% as dissatisfied, according to category B of ISO 7730 (2005), showed a comfort temperature of 21.1°C, with a comfort temperature range from 19.61 to22.61°C. CONCLUSIONS: Using the fraction of people dissatisfied with the environment (52.31%) as the cutoff, when the air temperature is equivalent to 20.2°C, the lowest percentage dissatisfied by the cold and heat in the environment occurs simultaneously.

Published: July 2020

Com base em um referencial teórico híbrido entre teorias críticas e pós-criticas e uma metodologia de bricolagem, analisaram-se os relatos de quatro participantes LGBTQIA+ (um homem gay, uma mulher lésbica, um homem trans e uma mulher trans) no intuito de descrever e refletir sobre as vivências e trajetórias que divergem da norma socialmente imposta através da qual prevaleceria uma relação sexo-gênero-desejo, especificamente no contexto de duas cidades do interior do sul do Estado do rio de Janeiro: Rio das Flôres e Valença. Compreendemos que há processos de exclusão e violência simbólica mais proeminentes neste contexto, o que leva muitas pessoas LGBTQIA+ a procurarem os grandes centros em busca de emprego e liberdade de expressão identitária.
LAS OTRAS “NGUIU´” DEL ISTMO DE TEHUANTEPEC - EXPERIENCIAS DE CAMPO
Authors: Flores Adriana Aguilar
Published: July 2020

El artículo presenta una reflexión sobre las vivencias de mujeres zapotecas “diversas” (nguiu´, en zapoteco, o lesbianas, como algunas de ellas se autodenominan) en la región del Istmo de Tehuantepec, Oaxaca. Principalmente, describe la experiencia de campo en espacio físico. Se específica el ambiente, la música y la interacción en el billar, así como el cuerpo y las miradas. Se concluye que si bien es cierto que las lesbianas zapotecas viven sus identidades bajo la sombra, en medio de un sistema que sí tiene contemplado un rol social para los muxes a la vez que sostiene el mantenimiento de ciertos aspectos de la heteronormatividad, también es cierto que se está gestando en estas sociedades cierto cambio social a partir de las estrategias impulsadas por las nguiu´de hacerse valer a partir de su inserción como profesionistas, por acciones en beneficio de la comunidad o de apoyo a la economía familiar.  De cualquier manera, frente a la alternativa de vivir siendo invisibles en su identidad sexual y su deseo por otras mujeres, ante el rechazo familiar y social, más allá de los mecanismos de simulación de una “normalidad”, siempre queda la posibilidad de la migración para las mujeres diversas del Istmo de Tehuantepec.

O presente dossiê temático é resultado de trocas e diálogos acadêmicos e afetivos estabelecidos em diferentes momentos entre nós, que vivemos em quatro contextos interioranos desse país de dimensões continentais. Como docentes de Universidades Federais localizadas nas regiões Nordeste (UFPI, UFRPE), Centro Oeste (UFGD) e Sul (UFPel), portanto, fora dos eixos metropolitanos das capitais, inquietamo-nos com as condições de invisibilidade de trabalhos, investigações e reflexões produzidas e conduzidas por inúmeros pesquisadores e pesquisadoras das mais diversas Instituições de Ensino Superior no interior desse Brasil profundo. Embora essa constatação não se refira a todos os campos de pesquisa, tal invisibilidade é patente quando se trata das discussões acadêmicas em torno das temáticas de gênero e sexualidades. Nesse sentido, este dossiê reuniu estudos e pesquisas sobre sexualidades dissidentes e as múltiplas expressões de gênero em contextos pouco visibilizados, tais como: cidades de pequeno e médio porte e/ou contextos rurais. O intuito foi discutir e refletir sobre as variadas formas de viver as identidades de gênero, práticas sexuais dissidentes, negociações e formas de resistência em contextos fora dos grandes centros urbanos.
Cannabis use and co-use in tobacco smokers and non-smokers: prevalence and associations with mental health in a nationally representative sample of adults in Great Britain, 2020
Authors: Hindocha Chandni , Brose Leonie , Walsh Hannah , Cheeseman Hazel
Published: July 2020

Background and aims: Cannabis and tobacco use is common in Great Britain. Use of both substances has been associated with mental health problems, but prevalence of their co-use and implications on mental health are unknown. We aimed to 1) estimate prevalence of cannabis use, frequency of use and routes of administration (ROA) among smokers and non-smokers; 2) to investigate mental health problems amongst non-users, tobacco-only, cannabis-only and co-users of both substances.
Design: National online survey fielded in February–March 2020.
Setting: Great Britain
Participants: Adults in Great Britain aged ≥ 18 year (n = 12,809)
Measurements: Tobacco use status (smoker [daily or non-daily] or non-smoker [never or ex-smoker]), cannabis use frequency (never to daily), detailed ROAs of cannabis, mental health disorders (depression, anxiety, and any). Weighted prevalence estimates were computed and correlates assessed using chi-squared tests and logistic regression.
Findings: In Great Britain in 2020, 7.1% of British adults had used cannabis in the past year. Tobacco smokers has greater odds of using cannabis in the past year (21.9%) and using cannabis daily (8.7%) than non-smokers (past-year: 4.7%; aOR=10.07, [95% CI: 8.4 -12.0]; daily: 0.7%; aOR=24.6, [95% CI: 17.96-35.55]). Co-administration with tobacco was common (46.2% of non-smokers, 80.8% of smokers). Co-users reported the highest prevalence of any mental health problem (54.2%) in comparison to cannabis-only (45.8%), tobacco-only (33.2%) and non-users (22.7%; all p≤0.05).
Conclusion: In a representative sample of Great Britain in 2020, tobacco smokers and non-smokers show significant exposure to combusted smoke and tobacco smoke. Self-identified non-smokers who regularly consume combusted cannabis, and smoked cannabis with tobacco warrant further attention. Co-use was associated with greater daily cannabis use, co-administration and mental health problems. Cannabis users should be considered a vulnerable population where rates of tobacco smoking are much higher than in the general population.
Intellectual Property Policy at The Neuro, an Open Science Institute
Authors: Roskams-Edris Dylan
Published: July 2020

In 2016 The Neuro, otherwise known as the Montreal Neurological Institute and Hospital, became the world's first open science institute. The Neuro's definition of and approach to open science is captured in its Open Science Principles. While most of the goals embedded in the principles have received increasing approval from researchers, funders, and other institutes, The Neuro's stance on intellectual property continues to see resistance. In this paper I describe how The Neuro conceives of the relationship between open science, neuroscience, and intellectual property; how it came to its current policy by examining both broad and Neuro specific innovation trends; and why it believes minimizing academic intellectual property is key to the future of neuroscience research.

Kayon is a shadow puppet character who symbolizes the world. In the Java world, there are two types of world concepts, namely the jagad ageng and the jagad alit. This study aims to examine the concepts of jagad ageng and jagad alit which are symbolized by the traditional kayons in purwa shadow puppets. The focus of this research study is to reveal the existence of Kayon Blumbangan and Kayon Gapuran as traditional kayons that have world essence, namely the jagad ageng and the jagad alit. Therefore, this study aims to reveal the existence and essence of Kayon Blumbangan and Kayon Gapuran as traditional kayons that store the concepts of jagad ageng and jagad alit. The method used in this research is iconography. Form theory which is divided into fields and ornament will become the main scalpel in analyzing the existence of Kayon Blumbangan and Kayon Gapuran. This research results that Kayon Blumbangan and Kayon Gapuran have the same shape structure with different widths of fields. The ornamental elements that form the kayon of the two traditional kayon are basically the same, namely forming four elements, including fire, water, wind, and earth. The four elements are the elements that make up the jagad ageng and the jagad alit. So, Kayon Blumbangan and Kayon Gapuran have a symbol of cosmological concepts regarding the concepts of jagad ageng and jagad alit.
INTERCULTURAL LEARNING: CHALLENGES FOR CURRENT SCIENCE EDUCATION

Published: July 2020

In the time of curricular reforms across the Europe another chance appeared towards increasing learners´ interest in science education, particularly in relation to the future job selection in the field of natural sciences and technology. Innovations in natural science instruction can be conducted in various ways, e.g. (Bílek & Klečková, 2006): (1) learners´ interest in natural sciences and their instruction (What am I interested in?; What would I like to learn?; What learning content should be learned?) – answers to these questions were discussed i.e. in the analysis of the international comparative study ROSE (Relevance of Science Education) (ROSE Project, 2018), (2) context of instruction (optimally – “school science”, application context, social context, personality context), (3) learning content (standards; Framework and School programmes; traditions; new topics) or (4) competences (key competences; “scientific literacy“; activities in natural science).

Published: July 2020

Learning and presenting chemical concepts at the triple level of chemical concepts provides opportunities for the development of misconceptions. The research aimed to identify potential misconceptions of chemical concepts: the states of matter, a pure substance, a mixture, an element, a compound, a physical change, and a chemical reaction at the sub-micro level when solving problems incorporating sub-microrepresentations. A total of 188 14-year old students, attending six different primary schools, participated in the research. A chemistry achievement test comprising five problems at the macroscopic, sub-micro, and symbolic levels was used to obtain data about students' misconceptions of selected concepts. The results showed that the majority of students had formed inadequate mental models (misconceptions) for the chemical concept of the liquid state of water (66.5%). The lowest level of misconceptions is related with the gaseous state of matter, because almost all students (98.5%) solved the problem correctly. It can be concluded that the results of the research are significant for chemistry teachers because they can: select and apply adequate educational strategies to avoid the deepening or development of misconceptions and make the courses practically oriented by analysing students’ misconceptions and develop teaching strategies to minimise these problems in the chemistry classroom. Keywords: chemical concepts, primary school, misconceptions, sub-micro level, symbolic level.

Published: July 2020

The purpose of this research is to examine Indonesian upper-secondary school students’ learning orientation in science via generating structural equation modeling of conceptions of, approaches to and self-efficacy in learning science, and seeking whether the model is significantly different based on gender. A total of 600 (63% females) Indonesian upper-secondary school students completed a questionnaire with three constructs – conceptions of, approach to and self-efficacy in learning science. Rasch analysis was conducted before testing the hypothesized model to examine the psychometric aspects of the instruments. Structural equation modeling featured with multi-group analysis-based gender was used to respond to the main research purpose. Findings indicated that the Indonesian upper-secondary school students had multiple conceptions of as well as multiple approaches to science learning that led to different senses of self-efficacy. Multiple conceptions and mixed approaches are the characteristics of students with achieving orientations. Most importantly, the current research found that conceiving learning science as memorizing was considered as the basis for the higher level of conceptions. The model significantly differed based on gender. Three main differences were Indonesian female students tended to be more conceiving science learning as memorization, using more surface motive and their self-efficacy was more impacted by their higher level of conceptions – applying and understanding than males. Based on findings, gender issues in orientations to studying and Indonesian science education curriculum are discussed. Keywords: learning strategies, conceptions of learning, gender, learning orientations, multi-group analysis, self-efficacy.

Stabilization of Al-Rustamiya Waste Water Treatment Plant Sludge Using Lime
Authors: Jasim Noor Ali , Ibrahim Jathwa Abdul Kareem
Published: July 2020

Sewage sludge treatment and discarding is a costly and environmentally sensitive problem. Sludge production will continue to increase as new sewage treatment plants are built and environmental quality standards are becoming stricter. The processes of stabilization using alkaline chemicals operating on a simple principle of raising pH to 12 or higher, with efficient mixing time and a suitable contact time ensured that microorganisms are either inactivated or destroyed. A 0.157 m3 rotating tank was designed to treat Al-Rustemeyia wastewater treatment plant’s sludge. Characteristics of raw sludge were examined through two parameters: pH, and fecal coliform analysis. Different lime doses of (0- 25) g CaO/100 g sludge were introduced to raw sludge. Samples were mixed manually in a rotating tank. Samples were analyzed 2 hours and 24 hours after mixing by rotation. pH and fecal coliform results were compared with EPA and national Iraqi guidelines. Results showed that 120 g of quicklime per 3 kg of sludge is acceptable to meet Class B criteria and 450 g per 3 kg sludge to meet Class A criteria according to EPA’s 40 CFR Part 503.The results indicated that lime treatment to stabilize sludge could be an appropriate solution provided that soil conditions do not deteriorate.
Inner-symbol Interference (INSI) reduction in OFDM system using distinctive characteristics of the pilot symbols
Authors: Bakkar Mohammad
Published: July 2020

This research presents a wireless communication system using Quadrature Amplitude Modulation (16QAM) depending on using of the Orthogonal Frequency Division Multiplexing (OFDM).  OFDM transmission system can effectively reduce inter symbol interference (ISI) caused by multipath fading, especially in the case of broadband data transmission. There are two kind of interference; inter symbol interference (ITSI) and inner symbol interference (INSI). ITSI is the interference caused by the delayed waves with larger than OFDM symbol duration, in order to avoid ITSI effectively, we insert guard interval every each OFDM symbol. On other hands, INSI is the interference caused by the delayed waves with less than OFDM symbol duration. To avoid INSI, this work proposes a new scheme in order to estimate the times of delayed waves by using distinctive characteristics of OFDM signal, which is inserted pilot signal periodically in frequency axis before IFFT at the transmitter. In this paper, we evaluate the estimation accuracy of the proposed estimation method and the BER performance of the proposed system under multipath fading environment by computer simulation with MATLAB.

The present study was conducted to evaluate the antioxidant, antidiarrheal and analgesic activities of Vachellia farnesiana (L.) Wight & Arn. The methanol extract of V. farnesiana and its different fractionates were subjected to in-vitro assay for the determination of total phenolic content and antioxidative potential. The ethyl acetate soluble fraction (EASF) exhibited the highest free radical scavenging capacity (IC50 value of 21.49 ± 1.04 μg/ml) as compared to that exhibited by the standard butylated hydroxyl toluene (BHT) (IC50 value of 20.41 ± 0.05 μg/ml). Such prominent antioxidative potential was further reinforced by a phenolic content of 39.26 ± 0.85 mg of gallic acid equivalent per gram of extract. The plant extract, at the dose of 400 mg/kg body weight, reduced castor oil-induced diarrhea in mice model by a statistically significant (p < 0.05) margin of 47.62%, while the standard loperamide produced 66.67% reduction of diarrheal feces. The central and peripheral analgesic activities of the crude methanol extract of V. farnesiana (MEVF) was determined by tail flick- and acetic acidinduced writhing methods, respectively, in Swiss albino mice. In the tail flick method, oral administration of MEVF at doses of 200 and 400 mg/kg body weight exhibited 221.09 and 237.09% elongation of pain response time, respectively, after 90 minutes of administration whereas the standard morphine effectuated 518.34% elongation within the same time. Furthermore, the same doses of the extract illustrated 63.27 and 69.39% reductions, respectively, in the acetic acid-induced abdominal constrictions in mice. Compared to the standard acetylsalicylic acid with 75.51% inhibition, statistically significant (p < 0.05) peripheral analgesic activity was established. The results of the present investigations suggest that methanol extract of V. farnesiana possesses antioxidant, antidiarrheal and analgesic activities which eventually indicates the presence of biologically important phytoconstituents within the plant that needs further exploration.
