Does kurtosis measure the peakedness of a distribution?
Authors: Kochański Błażej
Published: December 2022

The aim of the article is to present and justify the interpretation of the classical kurtosis as a measure of fat-tailedness and to propose modifications in the relevant didactic content. Many Polish academic textbooks describe kurtosis (or excess kurtosis) as a measure of the ‘slenderness’, ‘peakedness’ or ‘flat-toppedness’ of a distribution. This interpretation is incorrect. Kurtosis in fact measures the level of the dispersion of the values in the tails of the distribution or, in other words, the intensity of the extreme values. The article illustrates why the older interpretations which refer to the shape of the peak of the probability density function are incorrect. The study provides examples of leptokurtic flat-topped distributions and platykurtic peaked distributions. Using data from the 2000–2015 Social Diagnosis, the paper demonstrates that in empirical studies, the value of the kurtosis results from the level of the extremity of the outliers. New formulations are proposed which could replace the current, incorrect ones in statistical didactics.
The effect of whole-body vibration on spasticity in post-stroke hemiplegia: A prospective, randomized-controlled study
Authors: Yurttutmuş Zeynep Rukiye
Published: December 2022

Objectives: This study aims to investigate whether whole-body vibration (WBV) has an anti-spastic effect on the ankle plantar flexors. Patients and methods: This single-blind, prospective, randomized-controlled clinical study included a total of 48 patients with chronic stroke (33 males, 15 females; mean age: 60.7±10.9 years; range, 25 to 80 years) between May 2019 and February 2020. They were randomized into two groups: WBV group (n=24) and sham WBV group (n=24). A training program of 12 sessions (three days a week for four weeks) was applied regularly in both groups. The spasticity degree of the plantar flexors was evaluated by using both a subjective assessment method (modified Ashworth scale [MAS]) and several objective assessment methods (Hmax/Mmax, homosynaptic post-activation depression [HPAD], and torque) before and after the training program. Results: There were no significant changes in the torque values, Hmax/Mmax, and HPAD level after the training program in both groups (p>0.05). However, the MAS score in the WBV group significantly decreased (-9.0%), but no change in the control group was observed (0.7%) (p=0.027, effect size = 0.32). Conclusion: The objective assessment methods for spasticity show that WBV has no anti-spastic effect.
Ischemic stroke cases presenting with hand weakness mimicking peripheral neuropathy
Authors: Morkavuk Gulin
Published: December 2022

Pure motor monoparesis due to ischemic stroke involving a single extremity is a rare condition that can be easily misdiagnosed. Herein, we present three cases with isolated upper extremity monoparesis. All of our patients had weakness in the left hand. They were previously evaluated in other centers and were diagnosed with peripheral neuropathy by electromyography. When patients whose complaints did not resolve were admitted to our clinic, we performed electromyography again and observed that it was normal. Hereupon, we detected ischemic infarctions in cranial magnetic resonance imaging that would explain the patients' complaints. Isolated monoparesis mimicking peripheral neuropathy is a rare symptom in stroke patients. Pure motor monoparesis should be kept in mind in every patient presenting with acute-isolated monoparesis, and neuroradiological imaging should be performed.

Published: December 2022

Drought is one of the major factors limiting the growth and productivity of cucumber (Cucumis sativus L.) that adversely affects the desirable physiological and biochemical parameters. Thus, a field experiment was conducted during 2013â€“14 with 25 diverse genotypes of cucumber under four levels of irrigations, viz. 100% (control), 75%, 50% and 25% of the recommended irrigation. The yield reduction was as high as 51.97% under 25% of recommended irrigation. The physiological parameters such as proline, reducing sugars and phenol content increased significantly (P=0.05) as the drought stress increased from 100% irrigation to 25% irrigation level. In contrast, the relative water content (RWC), chlorophyll stability, membrane stability index (MSI) and fruit yield decreased signiï¬cantly (P=0.05) with the increase in the intensity of drought stress in all genotypes. Among 25 genotypes DGC-1, DGC-19 and WBC- 13 recorded better RWC, MSI, and lower yield reduction, while DGC-8, GS-3 and Barsati were highly sensitive to drought under all deficit irrigation levels (75%, 50% and 25%). These contrasting genotypes identified will be useful for mapping quantitative trait loci (QTLs) or genes for drought tolerance, and the best performing genotypes will be useful directly or as donors for genetic improvement in yield stability and water use efficiency in cucumber.

Authors: KAUR PARAMJIT , BHULLAR MANMEET BRAR
Published: December 2022

The present study was conducted to determine the effects of four acaricides on four different populations of twospotted spider mite, Tetranychus urticae, collected from cucumber (Cucumis sativus L.) under protected cultivation in 2016 and 2017. The statistical differences were found in susceptibility against treated acaricides and between populations collected from different regions of Punjab. The population with a resistance ratio of more than 60-folds with respect to an acaricide was considered as resistant population. Among all tested acaricides, the highest resistance ratio was reported to fenazaquin (62.52 to 212.55 folds) in population collected from Hoshiarpur, Patiala and Bathinda. Low to moderate level of resistance was reported against spiromesifen (3.76 to 32.10 folds). Propargite (14.64 to 22.17 folds) and fenpyroximate (17.10 to 32.10-folds) showed moderate level of resistance in T. urticae. The collected populations of T. urticae on cucumber under protected cultivation showed moderate to very high level of resistance to spiromesifen, propargite, fenpyroximate and fenazaquin, respectively in Punjab.

Published: December 2022

An experiment was conducted to study the effect of different combinations of pruning and plant nutrition on growth and yield of guava (Psidium guajava L.) during 2015â€“16 and 2016â€“17. The maximum number of new shoot emergence (6.69), number of flower bud emergence per shoot (14.10), fruits/shoot (12.01), fruit set (84.61%), fruits retained per shoot(9.28) and yield (24.13 kg/plant) was recorded with pruning at 20 cm from the shoot apex. Whereas, higher shoot length (62.26 cm) and shoot diameter (5.35 mm) was associated with pruning at 40 cm from the shoot apex. The minimum effect was recorded in unpruned shoot. Different sources of nutrition also affected growth, flowering, fruiting and yield of guava. In general, application of fertilizers through combination of organic, inorganic sources and biofertilizers exhibited the maximum number of new shoot emergence (6.23), shoot length (64.73 cm), shoot diameter (5.52 mm), number of flower bud emergence per shoot (13.33), fruits/shoot (11.76), fruit set (87.02%),fruits retainedper shoot (9.76). The highest per plant yield (24.23 kg/plant) was recorded with the application of 5 kg Farm Yard Manure + 2 kg Vermi-Compost+ 75% Recommended dose of fertilizer (225:150:150 g NPK) + Azotobacter 150g + PSB 100 g/plant. The interaction of pruning intensity and fertilizers was significant on yield and yield attributes. The maximum yield (31.03 kg/plant) was recorded in P2F6 with B:C ratio of 6.52.

Published: December 2022

The field efficacy of pre- and post-emergence herbicide combinations for control of complex weed flora in dual purpose tall wheat was evaluated in a field study conducted at Research farm of CCS HAU Hisar (Haryana) during rabi of 2015-16 and 2016-17. Phalaris minor Retz., Rumex dentatus L., Convolvulus arvensis L., Medicago denticulata Willd., Cirsium arvense (L). Scape, Cyperus rotundus L. etc. were major weeds in experimental area. Application of herbicides in both growing seasons reduced weed density and increased wheat grain yield as compared with weedy. After cutting of wheat for fodder, total weed density was reduced under application of pendimethalin 1500 g/ha PRE fb pinoxaden + metsulfuron (50+4) 2 WAC (week after cutting at 55 DAS), pendimethalin 1500 g/ha PRE fb sulfosulfuron+ metsulfuron (30+2) 2 WAC and pendimethalin 1500 g/ha PRE fb clodinafop + metsulfuron (60+4) 2 WAC as compared to alone application of post emergence herbicides. During 86-115 DAS period, more crop growth rate was observed under sequential application of herbicides as compared to post-emergence herbicides. Among herbicidal treatments, significantly higher leaf area index, crop dry weight, grain yield and B:C ratio was reported under sequential application of herbicides which were significantly higher than weedy and alone pre- and post-emergence application of herbicides during both the years of study.

An experiment was conducted at research farm of Advanced Centre of Rainfed Agriculture (ACRA), Rakh Dhiansar SKUAST-Jammu, using factorial randomized block design (FRBD) with three replications to study the effect of planting densities on plant growth and productivity of maize varieties. The experiment consisted of two maize varieties, viz. Double dekalb and Mansar and six plant spacings of 40 Ã— 15, 40 Ã— 20, 50 Ã— 15, 50 Ã— 20, 60 Ã— 15 and 60 cm Ã— 20 cm. Varieties and planting density had a significant effect on plant height, dry matter accumulation, leaf area index (LAI) and yield attributes like cob length, cob girth, number of grain row/cob, number of grains/cob row, number of grains/cob, grain and stover yield. The variety Double dekalb attained significantly higher growth and yield attributing parameter values and grain/stover yield. Spacing of 50 cm Ã— 20 cm observed significantly higher values of grain yield and yield attributing characters. However, 40 cm Ã— 15 cm spacing achieved significantly higher values of plant height, dry matter accumulation, LAI and stover yields. Also the spacing of 50 cm Ã— 20 cm exhibited statistically higher values of N, P and K uptake while 40 cm Ã— 15 cm spacing recorded significantly lowest values of nutrient uptake. Among the varieties Double dekalb exhibited higher values of net returns and B:C ratio values while among the different spacingâ€™s, 50 cm Ã— 20 cm registered the highest net returns and B:C ratio values.
A viable mathematical model for seed moisture prediction in multiple species
Authors: Jacob Sherry R , Jha Girish K , Singh Gajab , M B Arun Kumar
Published: December 2022

Modeling of seed sorption kinetics have been routinely applied for predicting the equilibrium moisture content (EMC ) of processed products and the information is used for determining their drying and storage parameters. Similar information is also valid for the seed industry because moisture content of the stored seed would determine its longevity and quality. But in seed industry, the storage facilities are used for multiple species having distinct physical and biochemical characteristics and there is a need to explore and identify a single mathematical model that can comprehensively predict moisture sorption behaviour of a wide range of species. In the present study, the Modified Henderson model could effectively describe the sorption kinetics of Pea, Okra and Chilli and gave the best fit for the data, when analyzed using mean relative error (MRE, %), standard error of estimate/moisture (SEM) and randomness of residual pattern as observed in the residual plots.

Published: December 2022

The present study was conducted with the aim to characterize different indigenous pummelo genotypes based on 19 quantitative and 9 qualitative traits. Leaf shape, leaf margin shape, leaf apex shape, petiole wing, petiole wing shape, fruit shape, fruit apex shape, fruit axis, fruit surface texture and pulp colour were the main qualitative characters of study. The higher coefficients of variation were determined for petiole area (36.33%), juice quantity (17.38%), leaf area (14.50%) and fruit weight (14.22%). Principal component analysis (PCA) for quantitative traits indicated that six PCA had Eigen-value greater than one. The cumulative variation explained by six components, viz. leaf length, fruit width, leaf length: width ratio, leaf area, petiole area and lamina wing ratio accounted over 86.12 % variability. However, the result of the PCA for qualitative traits showed that three parameters namely leaf shape, leaf margin shape and leaf apex shape among 10 Principal Component Axis (PCA) had Eigen-values greater than one, and accounted for over 70.23% of the total variability. Based on PCA and coefficient of variation, traits like fruit weight, seed content, juice content, leaf and petiole area, leaf length, leaf width and leaf length: width ratio had significant involvement in pummelo diversity, and can be used in differentiating accessions of citrus.

Published: December 2022

The present investigation was carried out during 2011- 2012 in an apple orchard situated 1935 m amsl in Shimla, district in Himachal Pradesh in order to assess the effect of foliar nutrition of calcium on growth, yield, fruit quality and shelf-life of apple. Two commercial grade calcium formulation, viz. CaCl2 at 0.4, 0.5 and 0.6% and Ca(NO3)2 at 0.2, 0.4 and 0.6 % were sprayed once (75 days after full bloom), thrice (45, 60 and 75 days after full bloom) and five times (15, 30, 45, 60 and 75 days after full bloom). The experiment was laid out in randomized block design with 19 treatments (replicated thrice). Two years pooled data revealed that five sprays of 0.6% Ca(NO3)2 significantly increased annual shoot growth and leaf area, but reduced the total yield, fruit size and weight. However, results of storage studies revealed that five sprays of 0.5 and 0.6% CaCl2 significantly reduced the physiological fruit weight loss, retain higher fruit firmness, TSS and sugar contents and improve the shelf-life of fruits in ambient storage conditions.

Technical Guidance Note Level 3, No. 3: Application of design methods of post-fixed anchors in concrete
Authors: O'Regan Chris
Published: December 2022

The design of post-fixed anchors, also known as fasteners, requires a large number of variables to be considered, along with the ways in which these variables interact with one another. Comprehensive analysis and design methods have been developed to ensure all aspects are considered. This Technical Guidance Note introduces these methods and explains how they can be applied. It covers both mechanical and chemical fasteners. However, as anchors vary depending on the manufacturer, the note does not provide specific data on particular anchors, nor include a worked example. This note concludes a series of three about the design of post-fixed anchors. Readers should ensure they are familiar with Level 1, No. 29: Post-fix anchors and Level 2, No. 24: Principles of the design of post-fixed anchors before reading this note.

Published: December 2022

The Insurance companies always stand as the backbone of most developed economy, in which reinsurance companies serve as insurance companies' bedrock. This study investigated the evaluation of reinsurance mechanisms on listed Nigerian insurance companies’ performance and sustainability. The population of the study is to cover all listed insurance firms in Nigeria and a five-insurance company is randomly selected as sample size for seven years (2012-2018) in Nigeria. Multiple regression analysis is adopted to analyze the data. The study findings established the statistically insignificant relationship between return on assets (ROAs) and net retention ratio (NRR), net claim ratio (NCR), the net commission ratio (NCoR), the ceded reinsurance ratio (CRR) respectively because the p-value (0.481) in the ANOVA table is greater than 0.05, the study therefore, suggested the acceptance of null hypotheses. It is therefore concluded that the reinsurance mechanisms do not have effect on listed insurance companies' performance and sustainability in Nigeria.

Published: December 2022

In this study, efforts were made to investigate fresh semen parameters and to select a suitable extender for buffalo semen cryopreservation. Experiment I, fresh undiluted seminal parameters were determined while Experiment II, efficacy comparison of coconut water extender (CWE) with tris citric acid extender (TCAE) and skimmed milk extender (SME) was made. Four bulls single ejaculate was collected weekly for 5 and 10 weeks for Experiment I and II, respectively however osmotic pressure replicates were 16 and 6 for semen and seminal plasma, respectively. In Experiment I, each bull spermatozoa concentration, motility (%), semen volume and pooled semen percentage NAR, PMI, viability and MTT (3-(4, 5-dimethyl thiazol-2-yl)-2,5-diphenyl tetrazolium bromide) reduction rate was checked. In Experiment II, pooled semen added to extenders and then equilibrated (4oC) and filled to obtain 20×106 spermatozoa/0.5 ml straws before plunging in liquid nitrogen. Percentage thawed spermatozoa viability, normal acrosomal ridge (NAR), motility, DNA damage, plasma membrane integrity (PMI) and lipid peroxidation (nM) recorded. In Experiment I, seminal parameters as spermatozoa concentration (1226.43±71.48 million/mL), semen volume (2.84±0.14 mL), viability (90.05±0.71%), motility (77.13±0.71%), PMI (86.23±0.34%), NAR (94.67±0.30%) and MTT reduction rate (0.290±0.06) while osmotic pressure of seminal plasma (294.83±3.87 mOsm/kg) and semen (290.87±2.58 mOsm/kg) was recorded. In Experiment II, TCAE higher (P<0.05) sperm motility noted compared to CWE and SME whereas percentage viability, NAR, PMI, DNA damage was non-significant. Lipid peroxidation compared to SME and TCAE was higher (P<0.05) in CWE. In conclusion, based on sperm motility and lipid per oxidation, TCAE was more efficient for cryopreservation of buffalo semen.

Authors: - Yendraliza , Handoko Jully , Rodiallah Muhammad , Arman Chairusyuhur
Published: December 2022

This study objective was to determine the fertility of buffalo sperm in response to different types of diluent and equilibration times. The first research stage was arranged in completely randomized design with two factors, i.e., diluent types (tris egg yolk, andromed, and triladyl) and equilibration times (3 h, 4 h and 5 h). The second research stage was the fertility test of frozen semen that artificialy inseminated on 90 4-years-old buffalo-cows. The observed variables were the percentage of motility, abnormality, membrane plasma integrity, acrosome intact, recovery rate and pregnancy rate. The result showed that there was no interaction between diluent types and equilibration times on all observed variables. The best buffalo sperm fertility was produced from andromed and tris egg yolk compared to triladlil diluent. The best equilibration time for buffalo semen was 5 h rather than 4 h and 3 h.

Published: December 2022

Melanin is the pigment of skin (coat) and hairs in all mammals. The 954 bp long MC1R gene codes for the production of MC1R or the α-MSH receptors which are present on the melanosomes. These receptors regulate the synthesis of melanin pigments viz., eumelanin or phaeomelanin leading to black and reddish to yellowish pigmentations respectively. PCR-RFLP analysis of 138 bp region of MC1R gene was conducted in two buffalo populations having distinct coat colours; Nagpuri (black) and Purnathadi (whitish). Three genotypes, EDED, EDE* and E*E* were observed at frequencies of 0.86, 0.03 and 0.11 for Nagpuri and 0.74, 0.08 and 0.18 in Purnathadi buffaloes; similarly the observed gene frequencies for ED and E* alleles were 0.87, 0.13 and 0.78, 0.22 in Nagpuri and Purnathadi buffaloes, respectively. DNA-sequencing revealed a transition mutation (A→G) at 118 bp locus confirming polymorphism, however presence in both the population failed to point towards any specific role in body coat colour of buffaloes.

Published: December 2022

The genetic gains were estimated for milk production and persistency, derived from random regression models, using eigenvector indices, and they were compared with the traditional selection index. The data set contained 4971 test day milk yield recorded for 691 buffalo cows, daughters of 120 sires and 532 dams. The model included the random effects of direct additive genetic, permanent environment and error, whereas the fixed effects were herd test day, year and season of calving and parity, and as a covariate, it was milk days. The first and the 2nd eigenvalues explained 73.1 and 22.9% of the variation of the random regression coefficients, respectively, suggesting that the use of the first two eigenvectors is sufficient. Genetic responses in total milk yield (TMY) based on the first eigenvector index (Ie1) and that based on the conventional selection (IMY) have close gain of about 171 kg in each index. The second eigenvector index (Ie2) showed an increase in TMY (9.91 kg), and thus an increase in the persistency (0.86 kg). The TMY and persistency are the two economically important traits in dairy production, additional genetic gains in persistency and high genetic gain for TMY could be obtained using the 2nd eigenvector index (I*2).

Educación e ingreso salarial: análisis diferencial en graduandos de la Universidad Abierta para Adultos (UAPA), República Dominicana
Authors: Téllez Acosta Wilmer Jose , Rojas Acosta Edgar Edwin
Published: December 2022

El estudio analiza las diferencias por ingreso salarial desde los supuestos teóricos del capital humano centrado en la educación universitaria. A través de un análisis de varianza (ANOVA) evaluamos la hipótesis de nulidad de diferencia salarial en una población de graduandos del año 2019. Los resultados arrojaron que el sexo, la zona geográfica, el nivel de titulación, la modalidad de aprendizaje y el sector laboral son factores que explican las desigualdades salariales. En cuanto al área de especialidad, no se encontró variaciones en el salario, situación que contradice la hipótesis asumida a partir de la literatura. Se concluye que la relación educación-salario solo puede entenderse como parte del dinamismo institucional laboral mediado por sus objetivos.

Distant Learning during Covid-19 Epidemic
Authors: Rothkrantz Leon
Published: December 2022

During the academic year 2020-2021 Universities in the Netherlands were closed because of the COVID-19 pandemic. All real life lectures were replaced by distant learning. It was expected that during the academic year new innovative ways of digital teaching-learning have been developed. But it proved that most teachers used classical web-lectures to teach their classes. Even though students have access to learning material any time and any place, current tools for e-learning still have their limitations. The main shortcoming, compared to real life learning is the limited opportunity for human like interaction between student, teacher and material. Another problem is that web-lectures are self-paced programs, offered asynchronously. They allow students to take the course anytime, anywhere. This is an advantage for some students, but others miss the self-control to take and complete courses. They miss the social control of peer students and teachers. It proves that about 25% of students of Universities in the Netherlands suffer from burnout symptoms at the end of the academic year. These students suffered from feelings of loneliness, unhappiness, stress, nervousness, having a negative effect on their well-being sometimes resulting in a burn-out or depression. In this paper we report about a MOOC based on serious gaming technology, stimulating interaction and cooperation between participants.
The Quadrature of the Governance Triangle: on the Heritage of Idealism and Prometheus’ myth
Authors: Allaerts Wilfried
Published: December 2022

In this paper, the historical, philosophical and political roots of binary thinking are analyzed. The influence of a religious or ideological hegemony of symbolic nature, on patterns of thinking in philosophy, science and in other aspects of human interest are critically examined. Starting from the Foucauldian merger of biopolitics and state sovereignity – after a major world pandemic crisis – and a post-deconstructivist analysis of the role of written language and academic literacy, a closer look at contemporary developments is offered. In particular, the heritage of Idealism is investigated in the present notions of universal mathematics and loopholes claiming the unification of physics and mathematics and the digitalization and algorithmic quantification of all aspects of human life and culture. In contrast to these developments, we propose a renewed approach of reading and experiencing symbols in patterns of interpersonal communication, with special reference to the phenomenon of music.
Scratch and visual block programming in mathematics: perceptions of preservice teachers in Columbia
Authors: Saez-Lopez Jose-Manuel , Vazquez-Cano Esteban , Sevillano-Garcia Maria-Luisa
Published: December 2022

This research evaluates the use of visual block programming-based instruction and its possibilities in mathematics, from the perspective of future teachers. A visual programming environment was employed to introduce pre-service teachers to prepare mathematics activities and programming. The study followed a pre-experimental design with a sample of 65 pre-service teachers. A Wilcoxon test was used to evaluate the gains in the participants’ knowledge of computational concepts and attitudes towards Scratch as a pedagogic tool in mathematics. We analyzed open questions to evaluate the participants’ attitudes concerning programming applications, and their perception of advantages in the implementation of programming in mathematics. Although there is no significant improvement in learning, positive results were obtained for programming in the classroom, with significant improvements in motivation, active learning, fun, and the possibility of learning Cartesian coordinates and other mathematical concepts.
A ANTROPÓLOGA E OS QUILOMBOLAS
Authors: Pirani Denise
Published: December 2022

A Profa Denise Pirani foi nossa colega de trabalho no Departamento de Ciências Sociais da PUC Minas por muitos anos e era daquelas pessoas que todos nós aprendemos a gostar no seu mau humor cortante, insubordinado e mordaz, inclusive com ela mesma.

Sofisticada e, ao mesmo tempo, “pé duro”, ela se adaptou bem ao trabalho do Projeto de Extensão “Lições da Terra”, conquistando o carinho de colegas e estudantes, se inserindo nos mais engraçados “causos” nos sete anos em que participou ativamente tanto das atividades de formação acadêmica quanto nas de campo, de sistematização de informações e redação de artigos e peças técnicas.

Infelizmente, ela nos deixou, de forma prematura, em dezembro de 2021, e todos nós consideramos que esse número da Revista “Em Sociedade”, dedicado aos povos e comunidades tradicionais, deveria incluir um artigo seu, pela sua contribuição como professora, pesquisadora e extensionista na PUC Minas. Na falta de um trabalho inédito sobre esta temática, resolvemos resgatar uma contribuição feita para os Relatórios Antropológicos das comunidades quilombolas de Baú e Ausente, localizadas próximas a Milho Verde, no município do Serro. Tais relatórios, elaborados para atender a uma parceria da Universidade com o Instituto Nacional de Colonização e Reforma Agrária (INCRA), visavam a identificação e a delimitação de territórios quilombolas e contaram com a participação ativa da Profa Denise em cinco deles. Esses relatórios eram produzidos pela equipe do Projeto “Lições da Terra” a partir das contribuições que iam sendo elaboradas por cada membro, que eram costuradas em um todo lógico dentro dos seus objetivos gerais. Assim, parte da contribuição de nossa antropóloga foi incorporada ao RELATÓRIO ANTROPOLÓGICO DE CARACTERIZAÇÃO HISTÓRICA, ECONÔMICA, AMBIENTAL E SOCIOCULTURAL DA COMUNIDADE QUILOMBOLA DO BAÚ - SERRO – MG, mas, por se tratar de produto técnico de circulação restrita, achamos, na presente publicação, uma ótima oportunidade para divulgar suas análises sobre a temática, ainda que seja um texto elaborado em 2015. A própria Denise já escreveu outros trabalhos técnicos e acadêmicos mais recentes, mas esse ainda guarda o frescor dos primeiros contatos com a temática e com a realidade das comunidades quilombolas do Serro.

Esperamos, assim, não só homenageá-la pelo seu trabalho na PUC Minas, formando várias gerações de cientistas sociais, mas reconhecer a sua contribuição para a temática em questão, certos que sua memória como pessoa e profissional estará em nossos corações e mentes.
A DIALÉTICA GLOBAL-LOCAL:
Authors: Siman Frederico Magalhães , Oliveira Marcelo Leles Romarco
Published: December 2022

Neste artigo, realizamos uma análise do processo de territorialização da comunidade quilombola dos Jorge, localizada no município de Peçanha, pertencente a bacia do rio Doce, no Leste do estado de Minas Gerais. Buscamos compreender como que, ao longo do tempo, este grupo familiar, em interação com o seu meio biofísico e social, produziu o seu espaço, o seu lugar. Empreendemos, num primeiro momento, um esforço de reflexão sobre a relação global-local na contemporaneidade e suas expressões na produção do espaço e configurações territoriais. Num segundo momento, tratamos dos aspectos históricos, econômicos e ambientais que atravessam o processo de formação da comunidade. Para essa descrição, recorremos aos dados produzidos, entre 2014 e 2020, coletados por meio de observação participante, técnicas de diagnóstico participativo e entrevistas. Por fim, a título conclusivo, versamos sobre os aspectos do processo de formação da comunidade que evidenciam a articulação entre global e local e as verticalidades e horizontalidades que permeiam a formação do território que constrói e habita.
COMIDAS DE SANTO E QUIZILAS:
Authors: Lima Luiz Fábio Pinheiro , Oliveira Cláudia Luz de , Leite Marcos Esdras
Published: December 2022

O artigo apresenta reflexões sobre as práticas alimentares de um povo de terreiro demonstrando as dimensões dos saberes e tradições relacionadas à cozinha no Candomblé, através da produção das comidas de santo, pensando tanto nas questões relativas à alimentação quanto nas relações sociais constituídas na cozinha, focalizando as quizilas, isto é, as aversões ou alergias dos ancestrais, que se refletem em interdições alimentares e comportamentais para os iniciados. O terreiro e a cozinha são abordados como espaços de produção da identidade dos filhos e filhas de santo, segundo as características da tradição do Candomblé de Angola Bantu. O diálogo com a literatura antropológica sobre o Candomblé e os diálogos mantidos durante a realização da pesquisa de campo etnográfica, no terreiro de Candomblé Bakiso Ngunzo Ria N´Zaze, fundamentam a discussão que busca demonstrar a importância dos alimentos na preservação e continuidade dos ritos sagrados. O objetivo é evidenciar a cozinha do Candomblé como umas das ferramentas de sociabilidade e aprendizado dentro do terreiro, demonstrando a riqueza dos saberes envolvidos na transmissão de valores e ensinamentos da cultura afro-brasileira.
