Indiana's Probable-Impact Test for Reversible Error
Authors: Najam, Jr. Edward W. , Warner Jonathan B.
Published: December 2022

This Article addresses the operation and effect of the reversible-error doctrine under the Indiana Rules of Appellate Procedure when applied to the review of non-constitutional trial court errors. In particular, this Article reviews the history of Indiana’s standards for reversible error under the Indiana Rules of Appellate Procedure and demonstrates that the Indiana Supreme Court adopted the probable-impact test to enable the court on appeal to assess whether it can say with confidence that the error more likely than not affected the outcome of the trial court proceeding. Specifically, this Article reviews the history leading up to the adoption of Indiana Appellate Rule 66(A), the text of that Rule, how the Indiana Supreme Court applied the probable-impact test in the seven yearsfollowing the court’s adoption of the Rule, and how later opinions from the court have clarified the probable-impact test. However, some variance in the application of the probable-impact test has both persisted and re-emerged, and this Article identifies those deviations in the case law. This Article then concludes with advice for practitioners to tailor their arguments around the probable-impact test.
Validation of Non-Invasive CO2 Tolerance Field Test
Authors: Murphey Joshua T.
Published: December 2022

INTRODUCTION: Breathwork, or the specific act of controlling breathing to elicit a desired outcome, is not only a potential way to improve
one’s mental well-being but also to alter adaptative responses through gas exchange at the capillary level. Increasing tolerance to carbon dioxide
(CO2) has been positively correlated with improvement in athletic performance and reduction of stress and anxiety. However, there does not
exist a validated non-invasive test to accurately measure one’s tolerance to CO2. PURPOSE: The purpose of this study was to
validate the only currently known CO2 tolerance (CO2T) field test against measured maximal dissolved CO2 and maximal
ventilatory carbon dioxide (V̇CO2max) in endurance athletes. HYPOTHESIS: It was hypothesized that the novel
CO2T field test would have a strong positive correlation to clinical CO2 measurements, there would be no observable differences
in comparative values between the CO2T field test and clinical CO2 measurements between sexes, and there would be a negative
correlation between anaerobic capacity and CO2T. METHODS: Twenty-eight (n=28, 19 males, 9 females) participants reported to
the Human Performance Laboratory on two separate occasions, separated by 48 hours, for testing. Peak CO2 levels were generated via
repeated 30-second Wingate anaerobic power intervals with two minutes of rest in-between. Participants continued the Wingate tests until a plateau
of peak power was achieved or volitional fatigue. CO2 data were recorded at the end of each interval. Day one consisted of a study
orientation, informed consent, anthropometric measurements, CO2T field test, and ventilatory CO2 measurements during the repeated
Wingate tests. Day two consisted of a second CO2T field test, end-tidal CO2 (EtCO2), and lactate (BL) measurements
during the repeated Wingate tests. STATISTICS: Repeated measures ANOVA and paired t-test were used to determine if differences existed
between CO2T times, EtCO2, anaerobic capacity (AC), and blood BL values. Pearson correlation coefficient analysis was used to
determine if there was a relationship between CO2T times and all primary research variables. RESULTS: The CO2T field
test showed to have a very high degree of intra-rater reliability but did not show any validity to CO2 measurements. Statistical analysis
showed a high positive correlation between CO2T tests one and two (r = 0.989, p < 0.01) and no significant difference so an average score was used
for analysis. A moderate positive correlation to HRpeak for CO2Tavg (r = 0.38, p < 0.05), and an indirect correlation to EtCO2(1)
(r = -0.342, p < 0.05). Correlations between CO2T tests and all other variables did not reach statistical
significance. CONCLUSION: While reliable, the novel CO2T field test does not seem to be a valid measurement of physiological
levels of CO2. The test was shown to have a high degree of intra-rater reliability and could be used to show trends over time but does not
give an accurate portrayal of actual CO2 production, accumulation, and tolerance.
Disturbance, Vegetation Co-Occurrence, and Human Intervention as Drivers of Plant Species Distributions in the Sagebrush Steppe
Authors: Schaus Noonan Fiona Claire
Published: December 2022

Changes in fire regimes, invasive species dynamics, human land use, and drought conditions have shifted important plant species in the Northern
Great Basin (NGB)—including big sagebrush (Artemisia tridentata ssp.), conifers (e.g., Juniperus spp.) and invasive
annual grasses (e.g., Bromus tectorum). Characterizing how these overlapping disturbances influence species distributions is critical
for land management decision-making. Previous research has explored the individual effects of drought, wildfire, restoration, and invasive species on
sagebrush steppe communities, but the specific effects of these disturbances in context with one another remain poorly understood at a landscape scale.
To address this gap, I constructed multilevel conditional autoregressive (CAR) species distribution models (SDMs) to map the distributions of big
sagebrush, juniper, and cheatgrass on lands managed for grazing in the NGB, both with and without a history of fire. These models illuminate the
concurrent influences of species co-occurrences, drought, wildfire characteristics (e.g., fire size, time since fire, and number of fires), and
restoration treatments. For all SDMs, results indicate that species co-occurrence exhibits the strongest effect—between 1.23 and 19.2 times greater
than the next strongest predictor—on all species’ probability of occurrence, suggesting that vegetation co-occurrence meaningfully influences
landscape-scale species distributions. In portions of the NGB both with and without historical fire, number of fires and maximum vapor pressure
deficit (VPD) also exert substantial influence on the likelihood of species presence, and results indicate that restoration treatments have
broadly met desired outcomes for both sagebrush and juniper Narrowing down to only areas that have previously burned, however, models do not
support the efficacy of post-fire restoration. All versions of the SDMs, which rely on Bureau of Land Management-administered grazing allotments
as a spatial varying intercept, also explicitly point to the differential influence of long-term management regimes on species distributions.
These model predictions capture post-disturbance vegetation outcomes under changing fire, climate, and invasive species regimes and in the context
of human decision-making, in turn defining a plausible ecological space as these disturbance and management processes play out into the future.
Reproducible Prediction of Organic Semiconductor Properties Through Open Source Software Development
Authors: Rushing James
Published: December 2022

Semiconducting materials made from carbon-based molecules are potential replacements for inorganic semiconductors, but with lower costs of processing. Devices made from organic semiconductors can be produced at scale by inkjet printing and roll-to-roll manufacturing of these molecules in solution or melt phases. The efficiency of these organic devices is dependent on the structure of the active layer, so controlling the morphology of organic molecules through self-assembly during manufacturing is a key challenge to realizing their utility. Molecular self-assembly depends on the chemical structure of the molecules, how key moieties interact with each other and with any solvent present, and the thermodynamic paths that are sampled during processing. Computer simulations of molecular self-assembly can predict the structure and properties of candidate systems, and can improve the amount of information gained from more expensive trials performed in a wet lab when used to guide and explain experiments. Here we focus on the prediction of charge mobility in organic semiconducting materials, which requires a sequence of modeling calculations spanning many orders of magnitude across both time and space. We describe an open-source `pipeline' of calculations that serves as a virtual laboratory for the screening of organic semiconductors for their charge transport properties. We describe work on Planckton, a software package for managing molecular simulations of organic semiconductors, and MorphCT, a package for managing kinetic Monte Carlo simulations, the modularization and testing of which improves their transparency, usability, reproducibility, and extensibility. We measure improvements to Planckton and MorphCT by using them to study two organic molecules of interest in the photovoltaics field. In the first case study, of semiconducting polymer Poly-(3-hexylthiophene) (P3HT), we validate qualitative trends of charge mobility against prior work from both simulation and experiment. In the second case we predict the morphology and charge transport of the semiconducting macromolecule 3,9-bis(2-methylene-(3-(1,1-dicyanomethylene)- indanone))-5,5,11,11-tetrakis(4-hexylphenyl)-dithieno[2,3-d:2',3'-d']-s-indaceno[1,2-b: 5,6-b']dithiophene (ITIC). We find that our work modularizing Planckton improves the pace at which simulations can be iteratively tested. We validate the electronic structure predictions made by pySCF against those previously made by the more restrictively-licensed orca package. We measure specific features of local structure that contribute to large-scale mobility trends in P3HT and describe predictions of charge transport in ITIC. In sum we improve the software ecosystem for reproducibly predicting charge mobility in organic semiconductors.
f-divergence regression models for compositional data
Authors: Alenazi Abdulaziz Ahmed
Published: December 2022

The paper considers the class of $f$-divergence regression models as alternatives to parametric regression models for compositional data. The special cases examined in this paper include the Jensen-Shannon, Kullback-Leibler, Hellinger, chi^2 and total variation divergence. Strong advantages of the proposed regression models are a) the absence of parametric assumptions and b) the ability to treat zero values (which commonly occur in practice) naturally. Extensive Monte Carlo simulation studies comparatively assess the performance of the models in terms of bias and an empirical evaluation using real data examining further aspects, such as predictive performance and computational cost. The results reveal that Kullback-Leibler and Jensen-Shannon divergence regression models exhibited high quality performance in multiple directions. Ultimately, penalised versions of the Kullback-Leibler divergence regression are introduced and illustrated using real data rendering this model the optimal model to utilise in practice.

Published: December 2022

The choice of the most suitable statistical distribution for modeling data is very important. Generally, the new distributions are more flexible to model real data that present a high degree of skewness and kurtosis. In this paper, we define a new one-parameter lifetime distribution, so-called weighted-Lindley distribution. Some of its basic properties are investigated. Some classical and Bayesian methods of estimation have been used for estimating its parameter. The behavior of these estimators were investigated by a graphical simulation study. A real data set is analyzed to investigate the flexibility of the new weighted-Lindley distribution.

Published: December 2022

There have been concerns globally as to whether taking COVID-19 vaccination is harmful or not. In this study, we conducted an online survey to measure the knowledge and attitude of people, first about COVID-19, and second about COVID-19 vaccination—various analyses such as descriptive statistics, logistic regression, and support vector regression with k-fold cross-validation. The support vector machine and tuned support vector machine suggest a better fit based on cross-validation error. The results show that immigration requirements significantly explain why an individual would accept the COVID-19 vaccine. This study suggests that people in authority should look into people's concerns regarding taking the COVID-19 vaccine and address them accordingly. The study aims to draw the attention of the people to the concern that surrounds taking COVID-19 vaccination and explored various statistical techniques to draw inference.

Authors: Alabbas Alaa Abdul-Kareem , Alumery Abbas Oudah Abdulkhudhur
Published: December 2022

Natural reserves are of great environmental importance as well as being an economic and social resource, as their sites are distinguished as a unique geographical area, those with unique biodiversity, or other unique matters. Countries enact laws, regulations, and legislation regarding these nature reserves to protect them from deterioration, abuse, or over-exploitation of natural resources. From here began the research problem represented by the presence of weaknesses and gaps in the articles of the natural reserve system that negatively affected the management and safety of the reserves compared to regional laws and instructions. The descriptive approach was used in the current study. Accordingly, the most important laws and legislation of some neighbouring and regional countries of Iraq were reviewed, such as the Saudi Executive Regulations for the year 2020, Egyptian Law No. 102 of 1983, and the Jordanian System No. 29 of 2005, as well as Kurdistan Region Regulation No. 9 of 2011. The most important articles of each law and regulation mentioned above were reviewed. The basic subjects were developed for the purpose of comparison, such as requirements, standards, management of the reserve, prohibitions, and activities inside the reserve, as well as the issuance of special instructions for these laws and regulations. The findings show that the instructions for regional countries with sobriety and strength in legislation are stronger than the Iraqi nature reserves system. Also, the study mentioned the most important conditions, standards, and requirements for choosing a reserve.

Authors: Abed Amal R. , Mabdeh Shouib N. , Nassar Abeer
Published: December 2022

There is a growing interest in gated communities as residential developments for upper-middle-income residents in Amman, Jordan, but limited research has been conducted on this subject. Additionally, no clear codes or strategies exist to regulate these communities. Social sustainability has been recognized as a fundamental component of sustainability and residential communities since it concerns individuals’ interactions and livable communities. This can be determined through five indicators: personal relationships, social network support, civic engagement, levels of safety, and shared values and norms. Therefore, this research investigates the impact of these indicators on one’s social life in different typologies of residential development. This exploration involved a mixed-method approach that began with a spatial analysis of selected gated communities, a conventional community, and a survey of households. Subsequently, the results revealed that the mega gated communities were the best in terms of social sustainability in personal relationships, social networks, and civic engagement. These facts may relate to the availability of public spaces and facilities, which are either missing or limited in other developments. Such amenities are integral components of social infrastructure and involve diverse activities, necessitating design guidelines for residential development considering social sustainability.
A Policy Framework and Prediction on Low Carbon Development in the Agricultural Sector in Indonesia
Authors: Adetama Dwi Sartika , Fauzi Akhmad , Juanda Bambang , Hakim Dedi Budiman
Published: December 2022

Currently, Indonesia has adopted Low Carbon Development (LCD) in its Medium-Term Development Plan (RPJMN) 2020-2024. One of the priority activities is agriculture, which accounts for 12.21% of total greenhouse gas emissions. The agricultural sector is the victim affected by CO2 emissions, such as degradation, shrinkage of agricultural resources, land and water, shifting planting seasons, crop failures, decreased food production due to rising air temperatures, floods, and droughts. Greenhouse gas emissions are predicted to continue to increase along with the increasing demand for food. The purpose of this study is to predict and find an alternative policy framework for low-carbon development in the agricultural sector in Indonesia. This study uses a quantitative and qualitative approach by Artificial Neural Network (ANN), and multicriteria policy (MULTIPOL) analysis. The data were obtained through secondary data in 2014-2018, and the primary data are in-depth interviews, Focus Group Discussions (FGD), and field observations. The results of ANN show that the predictions of provinces that need to adopt low-carbon development in Indonesia are dominated in production centers such as Java Island, so an alternative policy framework using MULTIPOL is needed. Furthermore, this research establishes three scenarios, eight policies, twenty-six actions, and nine evaluative criteria in analyzing the LCD of the agricultural sector. The results indicate that LCD can be conducted by integrating the speed scenario (S2) with a value ranging from 6.3 (policy to increase capacity and quality of human resources) to 18.7 (circular economy). This scenario accommodates policies related to low carbon reduction and agricultural production increase, such as a circular economy, co-benefit adaptation strategies, low carbon technology innovation, and strengthening low carbon networks.

Authors: Adhi Yuli Prasetyo , Dewi Iga Gangga Santi , Turisno Bambang Eko
Published: December 2022

Mining, along with plantations, is one of the main economic backbones of the Indonesian provinces of Kalimantan. The main concern of extractive economics is deforestation and environmental damage that threatens natural sustainability. Most of the previous research focused on the issue of environmental sustainability in the industrial context and regional spatial planning. To fill this void, this study originally aims to analyze how local wisdom is useful in managing ex-mining reclamation practices. This research was conducted in Margahayu, Kutai Kertanegara, East Kalimantan Province. The method used in this research is empirical legal research by adopting a data-based approach. The results show that ex-mining reclamation in Margahayu aims to restore the land use according to its function and is beneficial for agriculture and small-scale plantations. The findings underline that the participation of local communities is very useful in restoring the function of the ex-mining land, due to their interest in rehabilitating spatial planning and ecological supports that are useful for their livelihoods. In this context, this finding requires inclusion of local interest-based participation as an important social infrastructure in reforestation and mine land reclamation in Kalimantan.
The Internal Model of Default Credit for Rural Banks in Indonesia
Authors: Monalisa Yani , Sugiarto
Published: December 2022

The urgency of the internal model of default credit for the rural bank in Indonesia is increasing due to the recent acceleration of the increase in Non-Performing Loans at rural banks. This research will formulate an internal model of default credit that can reduce the level of default risk in rural banks based on the explanatory sequential design of mixed research method. The findings of quantitative analysis integration by Chi-Square Analysis, Discriminant Analysis, and Logistics Regression analysis at BPR BKK Pekalongan Regency in 2021 will be explored further by qualitative research. Using nine variables that affect debtors' failure, this study finds that the interest rate is a variable that consistently affects the status of default loans using the integration of 3 analyses and qualitative analysis. The study results indicate that rural banks need to pay more attention to determining credit interest rates when prospective debtors apply for credit. The determination of interest rates is related to compensation for risks faced by rural banks in connection with asymmetric information about the debtor's ability to pay while considering the interest rate determined by the IDIC.
Natural, racional, social: razón médica y racionalidad científica moderna

Published: December 2022

El interés en investigar la inserción político-social de la medicina y de la sociología, sus profundas repercusiones, en términos de teorías y de prácticas, en la cultura y en las instituciones sociales, surgió de mi experiencia en analizar las políticas de salud y la medicina social en la historia contemporánea de Brasil. Poco a poco fue quedando claro para mí que ciertas concepciones, teorías y categorías, más que médicas o sociales, son biosociales, y están profundamente ligadas a políticas o instituciones sociales, formando parte de una cierta racionalidad científica: médica, sociológica, encaminada hacia la normalización de sujetos y hacia la constitución —o reproducción— de ciertas relaciones sociales. Las características de esa racionalidad, sus trazos históricos constitutivos, así como su desarrollo a lo largo de los últimos tres siglos, a través de las categorías básicas aquí citadas, fueron el objeto de análisis del libro. Es el resumen de este análisis, en parte histórico, en parte teórico, que constituye el presente texto.

Double diffusive convection is the phenomena that describes the convection driven by two differ-ent densities which have different rates of diffusion. A comparison of two temperature boundaries when i) both the surfaces are set at adiabatic temperature, and ii)upper free surface is adiabatic and lower rigid surface is isothermal cases, on surface tension driven double diffusive convection in a horizontal composite layer is studied analytically using exact method. For both cases i) and ii), the thermal Marangoni number (Tmn) is determined, which is the eigen value, for upper free and lower rigid velocity boundary conditions. The results indicate that the given system is a fluid dominant composite system and adiabatic-isothermal thermal boundary is more stable compare to adiabatic-adiabatic boundary condition.

Published: December 2022

The impact of non-uniform temperature gradients on Rayleigh-Darcy convection in a composite system of couple stress fluid is discussed. The composite system is bounded by stress-free surfaces and adiabatically insulated, and the fluid-porous layers are coupled by employing appropriate interfacial boundary conditions. To determine the eigen value, the regular perturbation method is used. The effect of dimensionless parameters on Rayleigh-Darcy convection is analysed graphically, and it is demonstrated that the couple stress parameter and couple stress viscosity ratio stabilise the system, while the opposite effect is observed for the Darcy number and thermal diffusivity ratio.

Child and consanguineous marriages among students from ethnic minorities have consequences and risks for schools, families, and society. This study's primary purpose is to research the perception, appraisal, and factors influencing educational initiatives to avoid child and consanguineous marriage among secondary school students from ethnic minority groups. This study surveyed 106 administrators, teachers, and students from secondary schools in Dien Bien province, Vietnam, using three questionnaires designed to measure perception, evaluation, and factors influencing educational activities to prevent child marriage and consanguineous marriage. To examine data, a descriptive analysis was performed. The results indicate that the administrators, teachers, and students of secondary schools for ethnic minority affairs have an average understanding of the role of educational activities in preventing child marriage and consanguineous marriage. In secondary schools for ethnic minority affairs, administrators, teachers, and students lack a strong understanding of the role of educational activities in preventing child marriage and consanguineous marriage; many students and teachers are indifferent to programs for preventing child and consanguineous marriage. This study contributes to the overall discourse of administrators at secondary schools for ethnic minority issues applying a variety of educational materials, forms, and strategies to prevent child marriage and consanguineous marriage among students.

Este artigo, cujo objetivo é apresentar reflexões sobre mulheres quebradeiras de coco babaçu e seus modos de vida, é resultado da pesquisa Cartografia social dos babaçuais: mapeamento social da região ecológica dos babaçuais, do Projeto Nova Cartografia Social da Amazônia (PNCSA). Como percurso metodológico, optou-se por mobilizar a História Oral na perspectiva de conhecer, a partir das narrativas orais, as histórias de vida das quebradeiras de coco babaçu e a relação de suas experiências com a região ecológica dos babaçuais. A História Oral foi utilizada por possibilitar o conhecimento sobre os modos de vida das mulheres e as territorialidades. Assim, busca-se compreender como os modos de vida das quebradeiras de coco reinventam o seu cotidiano, produzindo culturas. A partir do resultado da pesquisa, elaborou-se um mapa da região ecológica dos babaçuais (PNCSA), que compreende os estados do Maranhão, Tocantins, Piauí e Pará. Esses são os estados principais quando se apontam áreas devastadas por fazendeiros para produzir pecuária extensiva e plantações de soja e eucalipto, dificultando o trabalho das quebradeiras de coco. Por sua vez, essas mulheres e seus modos de vida elaboram resistências cotidianas e se organizam para enfrentar essa situação.
Beija-flor airborne redux
Authors: Estellita-lins Carlos
Published: December 2022

O trabalho discute a experiência de confinamento na crisecovid, a partir de uma situação “autoetnográfica”. Assume o desafio de uma etnografia multiespécie mínima em espaço padronizado pelos modos de existência ocidentais – uma sala e sua janela num apartamento. A questão do Antropoceno e das zoonoses é tematizada neste contexto de impasses escatológicos de adiamento do fim do mundo. O acontecimento convoca temas afins, partindo de beija-flores e outras espécies agenciadas por sua presença efêmera, a saber: experiência de adoecimento, solastalgia, empuxo ao discurso, teoria do claustro. O isolamento, que se tornou político – abriu-se para uma paisagem minimalista incontornável. Como um jardim zen ou um deserto havia uma paisagem aparentemente monótona e pobre em animais ou plantas por ser frequentada em minha própria janela. Igualmente, indicou como seria preciso acompanhar as etnografias multiespécie com ênfase nas experiências de “edge”, de animais ameaçados, de espécies urbanas imperceptíveis ou desvalorizadas.
Tecnologias de governo na gestão de uma população indígena em situação de deslocamento forçado: entre a proteção e o controle da infância Warao
Authors: Rosa Marlise
Published: December 2022

Neste artigo, a partir de um episódio que envolve a retirada compulsória de uma criança Warao dos braços de sua mãe por uma conselheira tutelar, busco refletir sobre a dimensão moral que perpassa as tecnologias de governo empregadas para administrar e regular a presença de uma população indígena em situação de deslocamento forçado dispersa por inúmeras cidades brasileiras. O fato ocorreu em 20 de julho de 2017, na cidade de Belém (Pará), quando a criança acompanhava a mãe na venda de artesanato na rua. Para a análise, utilizo-me de documentos que compuseram o processo judicial interposto à Vara da Infância e Juventude pela Defensoria Pública do Estado (DPE) a fim de que o poder familiar fosse restituído; discorro sobre a retórica de proteção das crianças, chamando a atenção para sua aplicação unilateral com a finalidade de criminalizar as famílias Warao; e, por fim, reflito sobre a economia moral da infância e seus efeitos sobre esse segmento específico da população refugiada em nosso país. Esse conjunto de elementos, como veremos, indica que a gestão da infância Warao no Brasil transita entre a proteção e o controle desses sujeitos e de suas famílias – esse último, note-se bem, comumente disfarçado de proteção.
Mandatory vaccination requirements and the green Covid-19 certificate: a fundamental rights perspective in Italy
Authors: Civitarese Stefano , Pignataro Micol
Published: December 2022

Since the Covid-19 pandemic outbreak in March 2020, governments worldwide have resorted to various measures to manage and contain the spread of the virus. In Italy, for example, severe restrictions on freedom of movement were enforced from the very beginning, and they lasted until the vaccination campaign picked up in Spring 2021. At that point, the executive started to lift the most severe measures progressively, and, at the same time, it began to use other legal instruments. For instance, besides progressively enforcing a compulsory vaccination requirement for some categories of people only, the executive introduced a novelty in the Italian legal system: the Green Covid-19 Certificate (or ‘Green Pass’), which not only became a condition to access venues and make use of services, but it also became a condition for the enjoyment or exercise of fundamental rights, including the rights to education and work. The aim of this paper is to assess the Italian Government’s decisions through the lenses of liberal democratic constitutionalism, reflecting upon the balance that was struck between public health and individual fundamental rights. This kind of assessment is especially important in times of emergency, as they are typically defined by fast-tracked and temporary decisions which may, nevertheless, “inadvertently” become embedded in the constitutional legal order.
O papel da Matemática na vida cotidiana: uma análise das concepções de professores de Matemática
Authors: Spacek Iuri Kieslarck , Ortigara Vidalcir
Published: December 2022

Tendo como pressuposto que a forma como os professores entendem a relação entre o conhecimento matemático e a formação do estudante, bem como o modo com que agem embasados ou não neste entendimento, são aspectos que influenciam as suas ações de ensino, o presente texto tem como objetivo investigar as inter-relações entre a concepção dos professores do conhecimento matemático manifesto na vida dos estudantes e suas possíveis implicações para o ensino. Para atingir esse propósito, buscou-se identificar a manifestação dos professores em relação ao lugar que ocupa o conhecimento matemático na vida dos estudantes e como esse papel influi no ensino. Foram entrevistados sete professores efetivos, formados a partir de 1991 e que lecionam para turmas dos anos finais do Ensino Fundamental em escolas públicas estaduais de uma cidade de Santa Catarina. As entrevistas, semiestruturadas, foram gravadas e transcritas, o que possibilitou a organização das falas em núcleos temáticos para a análise respaldada no materialismo histórico-dialético, em especial, nas elaborações teóricas sobre o Cotidiano, na Teoria Histórico-Cultural e em contribuições dos autores vinculados a Pedagogia Histórico-Crítica. Percebeu-se que as concepções dos professores valorizam de maneira positiva uma expressão imediata dos conceitos matemáticos na vida dos estudantes; que consideram haver uma natureza distinta entre a manifestação da Matemática na escola e em atividades fora dela; e que é necessário a vinculação entre a manifestação imediata da Matemática com a manifestação da Matemática no ensino escolar.
MEASURING THE IMPORTANCE OF WAREHOUSE LOCATION SELECTION CRITERIA USING BEST-WORST METHOD

Warehouse performance has a major role in improving the effectiveness of supply chain considering especially the location where the warehousing activities occur. Warehouse location selection criteria have been widely used by decision-makers and researchers to achieve operational efficiency and reduce operational costs in the supply chain. On the other hand, the location of the warehouse is usually evaluated and decided on individual basis. This research determines the weights of the warehouse location criteria obtained from literature, using the Best-Worst Method (BWM), a multi-criteria decision-making method. A questionnaire form was sent to five warehouse professional experts in different companies including suppliers, manufacturers, and distributors in Turkey. From the BWM results, we can understand that ‘Market’ criterion has the most influence on decision about warehouse location.
