Automatic Corporeal Gesture in a Flash: A performative theory of process
Authors: Rodic Milosh
Published: March 2024

My artistic practice and research explore automatic processes used throughout time that develop conceptual and physical aptitude in the performer; to transcend the status quo and experience alternative versions of embodied reality. In homage to Elvis Presley and the spirit of Rock and Roll, I define automatism as a process formulated as Automatic Corporeal Gesture in a Flash (ACG

) where I work to make art without fear from an inspirational sensation in my body. ACG

is inspired, authentic action that I do in a creative act through some kind of plan or set of parameters to get a material result; it is automatic action through diffraction in an apparatus, to produce material with qualitative data that can be considered for its meaning after the performance. Like having a conversation with someone, this approach helps me to understand things as they are, learning about their qualities. In ACG

I combine my vibration with the vibration of what inspires me. It is a relational act of co-agential meaning making. It is a performance process that uses perception and action intrepidly while in an apparatus to maintain corporeal balance, integrity and momentum during an event. Practising ACG

changes qualities in material, which changes the way meaning is made from it. These changes are always particular to each event. Our senses are physical and extra-sensory. My imagination contains qualitative, empirical data. I am using my corporeal senses to perceive my imagination’s inspiration, as I would also use my other senses and their correlating extra-sensory capabilities to perceive the material world around me. The meditative groove of my ACG

is a trance dance. Trance is maintaining the entrainment of one’s body to a frequency which focuses perceptive consciousness. How a piece is created carries discursive information. Qualities of the movement of the body and the marks it makes speaks about our corporeal condition as well as speaking of its perception of qualities through/of itself and its local and extra-local environments. I use ACG

to learn about the qualities that experience has had in my body, and this knowledge increases my ability to be more responsible and accountable as a receiver and transmitter of discourse, which is the function of my relationality. ACG

helps me to access my full body, and it allows me to coordinate and integrate all my other senses and their correlating extra aspects into my creative action. ACG

is what keeps sparking the dynamic process in which I realize my creative potential, and where I can expand my abilities to perceive more of the qualities of life.
Site-integrity: An embedded and embodied approach to practice-based research
Authors: Marsh Julie
Published: March 2024

Practice-based research in the arts typically uses artistic processes and creative artefacts as part of its methods and approach. The focus is often on exploring and understanding the creative process itself rather than simply producing a final product or outcome. Such approaches have evolved from the understanding that life and experiences of the world are multifaceted, and that art offers ways of knowing the world through a more experiential approach compared to the intellectual and verbal ways that have traditionally dominated western discourses of knowledge. When it comes to practice-based research in the arts, audiences can engage with representations in a sensory, emotional, psychological and intellectual manner, expanding and deepening their understanding and knowledge. This article examines the key features of practice-based research through an analysis of ‘site-integrity’. By making artworks with and for a site-specific community, site-integrity directly responds to the social, religious, political and architectural discourses present. By implicitly performing involvements in, as opposed to observations on site, the research activity becomes an embedded engagement in the world of which it is part. The aim of site-integrity is to ensure that the research process is beneficial to both the researcher and the site community and that the research outcomes are useful, relevant and applicable in the real world. The focus of this article is to critically examine the role of artistic fieldwork in research, as well as to explore the ethical implications and effectiveness of such methods of engagement. By questioning the role and impact of such methods, the article may contribute to ongoing debates around the use of artistic and creative approaches in research and the broader implications of such approaches for knowledge production and dissemination.

OPTIMIZATION OF THE METHOD OF ULTRASONIC EXTRACTION OF BIOLOGICALLY ACTIVE COMPOUNDS WITH AN ALCOHOL-WATER MIXTURE FROM THE FRUITS OF VACCINIUM VITIS-IDAEA L., GROWING ON THE KOLA PENINSULA
Authors: Sereda Lidiya Nikolaevna , Tsvetov Nikita Sergeevich
Published: March 2024

Lingonberry (Vaccinium vitis-idaea L.) is a profusely fruiting evergreen berry shrub, which is a hypoactic forest species, growing throughout the Kola Peninsula. Fruits have a number of significant therapeutic properties, such as antioxidant, antitumor, neuroprotective, decongestant, antibiotic, due to a significant content of phenolic compounds. The process of complete extraction of polyphenolic components from a complex plant matrix requires the development of extraction conditions aimed at maximum mass transfer of target components with minimal destruction of compounds. In connection with the prospects of using the fruits of lingonberry plants in the pharmaceutical and cosmetology industries, in this work, for the first time, optimization of the conditions of the method of ultrasonic extraction with a water-ethanol mixture using single-factor analysis and the Box-Benken algorithm was carried out. The kinetics of the extraction process is approximated by the second-order reaction equation. The optimal duration of extraction, the concentration of the extractant, the power of ultrasonic exposure, the diameter of the fractions of plant raw materials, the hydromodule and the extraction temperature were determined. The total content of polyphenols and antioxidant activity, as well as the degree of inhibition of free radicals, were determined. The results obtained can be used in the development of technologies for the production of components for use in the pharmaceutical and cosmetology industries.

Mangrove plants have been widely used by people in various regions of Indonesia as traditional medicine for the treatment of wounds, fever, diarrhea, and others. Extreme habitat in coastal areas with high salinity and low oxygen level makes mangrove plants produce a variety of unique secondary metabolites and are rich in antioxidants. Although there have been studies on phytochemicals and antioxidant activity conducted, the study of mangroves in Bali, Indonesia, has not been widely explored. This study aims to determine the compounds contained in mangrove leaf extract and their antioxidant activity. The species to be studied is Sonneratia alba, which is commonly found in the Ngurah Rai Mangrove Forest, Bali, Indonesia. In this experimental study, compound extraction was carried out by maceration method using n-hexane solvent. Phytochemical screening using qualitative methods and GC-MS was carried out to determine the phytochemical compounds in the extract, while 1,1-diphenyl-2-picrylhydrazyl (DPPH) method was used to determine antioxidant activity. The result showed that the n-hexane S. alba mangrove leaves extract display strong antioxidant activity with IC50 value of 64.432 ± 7.675 ppm. The qualitative phytochemical tests showed that the extract contained phenol and steroid, which are known to have antioxidant properties. Moreover, GC-MS analysis showed that there are two compounds with the largest %area namely gamma-sitosterol and dl-alpha-tocopherol (52.88% and 7.77%, respectively), which have been reported to have antioxidant activities. To conclude, these findings demonstrate that n-hexane extract of S. alba mangrove leaves from Ngurah Rai Mangrove Forest, Bali, to have potential antioxidant activity.

Cola nitida, also known as Kola nut, is a tropical plant native to West Africa and has a rich history of traditional medicinal use. In this narrative review, we aim to provide an overview of the protective effects of Cola nitida in various health and disease states. Cola nitida has been traditionally used for its medicinal properties, and its bioactive compounds include caffeine, alkaloids, tannins, flavonoids, and phenolics. These compounds contribute to its potential therapeutic effects. Here, we examine the potential benefits of Cola nitida in several areas of health, discussing its role in cognitive function, cardiovascular health, immune system function, gastrointestinal health, and metabolic and endocrine health. Relevant original articles available from PubMed, African Journals Online (AJOL), SCOPUS, and Google Scholar were retrieved using the keywords “cola” AND “nitida” without date restriction until July 17, 2023. Evidence suggests that Cola nitida may have positive effects on health, with indications of adverse effects only from its chronic usage. However, more research is needed to establish its efficacy and safety. Cola nitida holds promise as a natural remedy for various health conditions. Understanding the benefits and limitations of Cola nitida will contribute to its effective utilization in health and disease management.

Published: March 2024

As the world's largest delta, Bangladesh possesses distinctive geomorphology dominated by transboundary rivers, making it vulnerable to climatic hazards such as river erosion that causes severe loss of land and other resources. Using four Landsat imageries of 1991, 2001, 2011 and 2021 the current study analyzed the amount and trend of river erosion and accretion on the Teesta Floodplain of Bangladesh for three decades. Findings indicate that the Teesta River experiences severe bank erosion and accretion regularly, causing bank line shifting and thus significant affecting the land-use/land-cover (LULC) change of the area. Between 1991 and 2021, approximately 194 square kilometers of land were eroded, while an equivalent area of land was accreted. Approximately 1072 km2 of agricultural land was converted into other categories, with the settlement area gradually increasing. This trend of changes shows that agricultural land and water-bodies will reduce in the next two decades while barren land and settlement areas will increase. The agricultural lands and barren lands have a greater chance of being occupied by settlement areas. At the same time, crop production patterns will move to those crops that require less water due to the reduction of water-bodies. Reduced flow during the dry season and massive discharge during the monsoon from India's Gajoldoba barrage caused massive siltation and erosion. Comprehensive river management and restoration with an intergovernmental treaty or understanding between India and Bangladesh is required to resolve this crisis in the long run.
Assessment of Random Forest and Neural Network for Improving Land Use/ Land Cover Mapping from LIDAR Data and RGB Image: A Case Study of Magaga-El-Menia Governorate, Egypt
Authors: Taha Lamyaa Gamal EL-Deen , Mandouh Asmaa Ahmed
Published: March 2024

The goals of this article are to improve classification of land use/land cover information using LIDAR data and RGB images, as well as to compare the performance of various supervised machine learning classifiers (random forest and neural network) for extracting land use/land cover information. The 3D coordinates are first transferred to a high-resolution raster via interpolation. Height and intensity raster grids are formed. Second, various raster maps - a normalized digital surface model (nDSM), the difference of returns, and the LiDAR intensity image -are combined to create a multi-channel image. Five scenarios with different combinations were created. Finally, on the five separate datasets, several classifications based on random forest and neural network classifiers were performed. The classification findings were subjected to a quantitative accuracy check. A comparison of these five methodologies has been conducted. Following that, morphological operations were used to eliminate noise. The results revealed also that the fourth approach is the best followed by the third approach then the last approach then the second approach followed by the first approach. It was discovered that random forest classification outperforms neural network classification in terms of classification accuracy.

Published: March 2024

The Rizal Province was subjected to a series of natural and human-induced disturbances throughout the years. Currently, the area is undergoing urbanization which in turn results in shifts in the extent of impervious surfaces that can intensify heat-related health concerns, increase energy consumption for cooling, and alter local weather patterns. This study uses remote sensing images from to quantify the various environmental considerations that remain undocumented and unmapped for areas caused by changes in land use and land cover from Landsat Collection 1- Level 1 (Landsat 4-5 ™ C1- Level 1 & Landsat 8 OLI/ TIRS C1 Level 1) and calculated three parameters namely, (i) Land surface temperature (LST), (ii) Normalized Difference Vegetation Index (NDVI), and (iii) the Normalized Difference Built-up Index (NDBI). The results showed the following: (i) an increase in the vegetation cover from 1993-2020 showed a decrease in LST from 29.34°C to 24.03°C, (ii) the relationship between LST and NDBI is directly proportional, whereas an inversely proportional relationship can be observed between LST and NDVI, and (iii) there is a fluctuating LST due to the changes in the land cover of the study site for almost three decades. This implicates the extensive shift in the ambient temperature of Rizal which further emphasizes the effects of the modification in certain land use land cover classifications, especially in vegetation cover and urban development. This highlights how human-induced and natural factors significantly contribute to the release of heat and ambient temperature, thus, accentuating the need for sustainable urban planning.

Authors: Hariyanto Annisa Dira , Yudono Adipandang , Wicaksono Agus Dwi
Published: March 2024

The infrastructure of Malang City is currently being directed towards the eastern and southeastern parts, Kedungkandang District. Infrastructure plays an important role in the aspect of land cover change, which raises the complexity of the emergence of urban forms and dynamics. This study compares three models, Artificial Neural Network (ANN), Logistic Regression (LR), and Multi-Criteria Evaluation (MCE), to predict changes in land cover in the Kedungkandang District using the Cellular Automata (CA) approach. The prediction results indicate that the ANN and MCE models have the highest overall Kappa values (prediction accuracy), while the ANN and LR models have the highest location-specific Kappa values. However, overall, the ANN model demonstrates the highest accuracy and performance among the other two models. This research makes a significant contribution to urban planning by highlighting the importance of using machine learning-based technology to predict land cover changes in Malang City, particularly in the Kedungkandang District. Stakeholders can leverage this technology to design more effective and sustainable infrastructure policies and implement preventive measures to mitigate the negative impacts of uncontrolled urban growth.

Glycation of Matrix Proteins in the Artery Inhibits Migration of Smooth Muscle Cells from the Media to the Intima
Authors: Kuzan Aleksandra , Michel O. , Gamian A.
Published: March 2024

Formation and growth of atherosclerotic plaques have serious clinical consequences. One mechanism that occurs during atherogenesis is migration of smooth muscle cells from the middle layer of the artery to the intima, where they proliferate and are transformed into foam cells. This degenerative process is accompanied by glycation, by which proteins are modified and change the biomechanical and biochemical properties. The aim of the study was to determine whether glycation of collagen and elastin building the walls of blood vessels alters the adhesion and rate of myocyte migration. In vitro experiments included migration assays and immunocytochemical staining with anti α-actin, β-catenin anti-collagen type IV antibodies. It turns out that there is a tendency to decrease the number of cells that had migrated through the barrier consisting of glycated proteins as compared to the control. Adversely, the morphology of the cells cultured in the presence of glycated substrates is changed. The lower intensity of β-catenin staining indicates lower adhesiveness of such cells. It is proposed that glycation inhibits migration of smooth muscle cells from the media to the intima, which represents part of the anti-atherogenic mechanism.

Resistance against fungal decay of Scots pine sapwood modified with phenol-formaldehyde resins with substitution of phenol by lignin pyrolysis products
Authors: Karthäuser Johannes , Treu Andreas , Larnøy Erik , Militz Holger , Alfredsen Gry
Published: March 2024

Phenol-formaldehyde (PF) resins can be impregnated and cured in situ to improve the woods dimensional stability and decay resistance. In search of renewable alternatives, the substitution of phenol by lignin cleavage products (LCP) has been discussed. However, the different chemical nature may affect the performance of the resin against fungal decay, formaldehyde emission, and equilibrium moisture content. In this study, 30 % (w/w) of the phenol in PF resins were substituted by LCP obtained from microwave-assisted pyrolysis. Scots pine sapwood was modified with the resin. The decay resistance against Rhodonia placenta, Gloeophyllum trabeum, and Trametes versicolor was determined. Additionally, effects of specimen organisation within the Petri dish, different substrates, length of leaching, and type of inoculum were studied. Further, the materials water vapor sorption properties and formaldehyde emission were determined. All modifications effectively reduced fungal decay. With 10 % weight percent gain (WPG), initial decay was detected, while 20 % WPG and 30 % WPG provided efficient protection. The substitution of phenol increases the formaldehyde emission. While further reduction in formaldehyde in the resin admixture or formaldehyde scavengers may be required, the method described herein can be used to partly replace fossil-based phenol, while maintaining good fungal resistance.
Performance optimization of PERC solar cells based on laser ablation forming local contact on the rear

Published: March 2024

To improve the photoelectric conversion efficiency (η) of the solar cell, a green wavelength (532 nm) laser source in a nanosecond range was used to ablate the passivated emitter and rear cell (PERC) to form the contact holes. If the laser ablation hole opening process was not set properly, the diameter or the external expansion of holes would be too large, causing the decline of the PERC performance. The Gaussian distribution of the laser is regulated by the output power (P
o) and the repetition frequency (f
rep) of the incident pulse laser, so that the optimized morphology of holes is obtained on the back of the PERC solar cells. After the contact holes are screen printed by the aluminum paste, the local back surface field is finally formed. The experimental results showed that the outward expansion decreases obviously with the increase of laser P
o. Second, the spacing of the holes decreases with the increase of the laser f
rep. It was found that under the laser P
o of 33.0 W and f
rep of 1,400 kHz, the η of the industrial PERC solar cells was the highest. The Quokka simulations indicated that small outward expansion, small diameter, and long spacing of holes would further decrease the recombination parameter in the rear surface. With the optimized morphology of contact holes and the low contact resistance, the PERC cell’s calculated V
oc and η improvements were 6.5 mV and 0.48%, respectively, which was verified with experimental findings.
Improving general practice management of patients with chronic musculoskeletal pain: Interdisciplinarity, coherence, and concerns
Authors: Larsen Jesper Bie , Borregaard Pernille , Thomsen Janus Laust , Rathleff Michael Skovdal , Johansen Simon Kristoffer
Published: March 2024

Objectives

Management of patients with chronic musculoskeletal pain (CMP) remains a challenge in general practice. The general practitioner (GP) often experiences diagnostic uncertainty despite frequently referring patients with CMP to specialized departments. Therefore, it remains imperative to gain insights on how to optimize and reframe the current setup for the management of patients with CMP. The objective was to explore GP's perspectives on the challenges, needs, and visions for improving the management of patients with CMP.

Methods

A qualitative study with co-design using the future workshop approach. Eight GPs participated in the future workshop (five females). Insights and visions emerged from the GP's discussions and sharing of their experiences in managing patients with CMP. The audio-recorded data were subjected to thematic text analysis.

Results

The thematic analysis revealed four main themes, including (1) challenges with current pain management, (2) barriers to pain management, (3) the need for a biopsychosocial perspective, and (4) solutions and visions. All challenges are related to the complexity and diagnostic uncertainty for this patient population. GPs experienced that the patients' biomedical understanding of their pain was a barrier for management and underlined the need for a biopsychosocial approach when managing the patients. The GPs described taking on the role of coordinators for their patients with CMP but could feel ill-equipped to handle diagnostic uncertainty. An interdisciplinary unit was recommended as a possible solution to introduce a biopsychosocial approach for the examination, diagnosis, and management of the patient's CMP.

Conclusions

The complexity and diagnostic uncertainty of patients with CMP warrants a revision of the current setup. Establishing an interdisciplinary unit using a biopsychosocial approach was recommended as an option to improve the current management for patients with CMP.
Neuropathic pain after surgery – A clinical validation study and assessment of accuracy measures of the 5-item NeuPPS scale
Authors: Andersen Kenneth Geving , Christensen Karl Bang , Kehlet Henrik , Mejdahl Mathias Kvist
Published: March 2024

Objective

The aim of this study was to validate the Neuropathic Pain for Post-Surgical Patients (NeuPPS) scale against clinically verified neuropathic pain (NP) by quantitative sensory testing (QST) as well as evaluation of other psychometric properties. The NeuPPS is a validated 5-item scale designed to evaluate NP in surgical populations.

Methods

Data from 537 women aged >18 years scheduled for primary breast cancer surgery enrolled in a previous study for assessing risk factors for persistent pain after breast cancer treatment were used. Exclusion criteria were any other breast surgery or relevant comorbidity. A total of 448 eligible questionnaires were available at 6 months and 455 at 12 months. At 12 months, 290 patients completed a clinical examination and QST. NeuPPS and PainDETECT were analyzed against patients with and without clinically verified NP. NP was assessed using a standardized QST protocol including a clinical assessment. Furthermore, the NeuPPS and PainDETECT scores were psychometrically tested with an item response theory method, the Rasch analysis, to assess construct validity. Primary outcomes were the diagnostic accuracy measures for the NeuPPS, and secondary measures were psychometric analyses of the NeuPPS after 6 and 12 months. PainDETECT was also compared to clinically verified NP as well as NeuPPS comparing the stability of the estimates.

Results

Comparing the NeuPPS scores with verified NP using a receiver operating characteristic curve, the NeuPPS had an area under the curve of 0.80. Using a cutoff of 1, the NeuPPS had a sensitivity of 88% and a specificity of 59%, and using a cutoff of 3, the values were 35 and 96%, respectively. Analysis of the PainDETECT indicated that the used cutoffs may be inappropriate in a surgical population.

Conclusion

The present study supports the validity of the NeuPPS as a screening tool for NP in a surgical population.
Weber e a construção da experiência sociológica
Authors: Antonio Santana Fernando
Published: March 2024

Este artigo é um estudo sobre a metodologia das ciências da cultura de Max Weber. Faz-se, aqui, uma incursão sobre um ponto bastante específico na metodologia de Weber, que é o processo de "conceber" um domínio da realidade, isto é, transformar a experiência vivida, a vivência ou o imediatamente vivido em conceito e, consequentemente, em conhecimento suscetível de alcançar validade empírica. Esse movimento do vivido para o conceito é o que chamo aqui de a "construção da experiência sociológica". Para realizar tal empreitada, debruço-me, basicamente, sobre as produções weberianas do começo do século XX, em especial "Roscher und Knies", escrito em duas partes em 1903 e 1906.
A Razão Punitiva:
Authors: Boni Matheus
Published: March 2024

Inspirada em modelos da Escolha Racional do Crime que renovaram o conceito de Dissuasão Criminal com ferramentas da microeconomia neoclássica, e formuladas como estratégias de segurança pública por consultorias militares, a Criminologia Gerencial advoga o uso de modelos de gestão de riscos para a gestão do policiamento e do controle punitivo dos conflitos e desvios sociais, naturalizando a seletividade policial-penal e a própria ordem social de mercado. Para os países da periferia do mundo capitalista, porém, a criminologia gerencial se traduziu na promoção de uma segurança pública centrada no policiamento militarizado e no encarceramento seletivo, levando à identificação de parte da sua população, quando associada a um conjunto heterogêneo de ameaças à ordem estabelecida, como possíveis inimigos internos do Estado.

Published: March 2024

Este trabalho tem por objetivo problematizar a noção de corte epistemológico – e sua variante, ruptura epistemológica – na reflexão sobre os efeitos produzidos pelas ideias de Ferdinand de Saussure no campo da investigação linguística. Além disso, visa a discutir a produtividade da noção de movimento, como uma analogia alternativa às noções de corte e de ruptura para a epistemologia saussuriana. Para tanto, a partir de um levantamento bibliográfico, este estudo apresenta uma série de reflexões realizadas por Claudine Normand, especialista da fortuna saussuriana, em que a analogia do corte ou da ruptura é emprestada e abdicada. Em seguida, são apresentadas reflexões da pesquisadora brasileira Eliane Silveira, que lança mão da noção de movimento, a qual tem ganhado adeptos na literatura saussuriana. A partir disso, é possível argumentar em favor de um deslocamento da analogia do/da corte/ruptura em direção à analogia do movimento, a qual, de nosso ponto de vista, é mais representativa da epistemologia saussuriana.
Estudio neurolingüístico sobre el humor verbal
Authors: Delgrosso Adriana
Published: March 2024

Este trabajo intenta demostrar la importancia de los conceptos saussureanos tanto a la hora de identificar síntomas en la patología neurolingüística como de idear recursos que permitan llevar a cabo una terapéutica basada en el humor verbal. Al sentido del humor y a la risa se les atribuyen importantes beneficios físicos, psicológicos y sociales. El chiste es un dicho breve u ocurrencia aguda y graciosa que contiene un juego verbal o conceptual capaz de provocar la risa y que muchas veces se encuentra ilustrado por un dibujo. En el síndrome afásico, la pérdida de la comprensión del lenguaje no solo afecta la comunicación interna y con los demás sino que también impide disfrutar del humor verbal porque éste se basa en la ambigüedad léxica. En este trabajo se analizan chistes que involucran juegos de palabras desde los conceptos de la lingüística estructural, con el fin de proponerlos como recurso terapéutico en la última etapa de recuperación del paciente afásico de grado leve. Se destaca la formación lingüística que debe poseer el terapeuta del lenguaje.
Cantos de trabalho

No presente artigo, investigo a possibilidade de se entender cantos de trabalho como atividades discursivas a partir de uma perspectiva poética e meschonniciana. Através da observação de cantos de marinheiro franceses e seu funcionamento, busco entender de que maneira esse gênero de canto se enquadra no escopo dos estudos de linguagem, o que se dá a partir da releitura e do deslocamento de conceitos que, mesmo em Meschonnic, nascem em Saussure e em Benveniste. Assim, proponho-me repensar noções como a de sistema, de ritmo e de discurso a fim de promover uma abertura que permita entender o sujeito inteiro na linguagem e a pluralidade de produções, o que viabiliza o entendimento de outras formas de constituir sistema e sentido.

O objetivo desta pesquisa é analisar a exaltação do corpo feminino negro como fonte de autoafirmação, de segurança e de liberdade no conto Química ou Física, de Miriam Alves, da antologia Juntar Pedaços (2021). A análise está comprometida com teorias e conceitos próprios da literatura afro-brasileira contemporânea na intersecção com paradigmas teóricos oriundos do pensamento feminista negro, tais como o Cuírlombismo, de Tatiana Nascimento dos Santos; a Poli(poé)tica, de Flávia Santos de Araújo; e os feminismos negros de Patricia Hill Collins e bell hooks. Ao conectar a literatura e o feminismo negro, engendra-se um meio de liberdade e de transcendência, que podem ser percebidas quando são analisadas a partir de conceitos endógenos de intelectuais negras: Conceição Evaristo (2005); Tatiana Nascimento dos Santos (2019); Flávia Santos de Araújo (2022), dentre outros nomes que inscrevem suas teorias no campo da literatura afro-brasileira e das expressões afro-femininas.

As obras analisadas apontam a realidade das mulheres que diariamente convivem com as convergências das formas de estereótipos, opressão e violência. Este trabalho abrangerá as cidadãs negras e brancas pobres, podendo assim perceber que, além da questão racial, há também a problemática da classe social em que essas estão inseridas, o que as colocará em uma situação de marginalização. Dessa forma, apresenta-se, a condição da mulher na sociedade brasileira contemporânea, as questões que permeiam a mulher negra nas narrativas, como os abusos e a relação entre gênero e classe, demonstrando a condição das mulheres periféricas negras e brancas. Para isso, a pesquisa realizada foi bibliográfica e descritiva a partir da leitura de Davis (2016), Gonzalez (2020), Saffioti (2015), entre outros. Ao fim, recomendamos encaminhamentos futuros.

Pain perception arises from the integration of prior expectations with sensory information. Although recent work has demonstrated that treatment expectancy effects (e.g., placebo hypoalgesia) can be explained by a Bayesian integration framework incorporating the precision level of expectations and sensory inputs, the key factor modulating this integration in stimulus expectancy-induced pain modulation remains unclear. In a stimulus expectancy paradigm combining emotion regulation in healthy male and female adults, we found that participants’ voluntary reduction in anticipatory anxiety and pleasantness monotonically reduced the magnitude of pain modulation by negative and positive expectations, respectively, indicating a role of emotion. For both types of expectations, Bayesian model comparisons confirmed that an integration model using the respective emotion of expectations and sensory inputs explained stimulus expectancy effects on pain better than using their respective precision. For negative expectations, the role of anxiety is further supported by our fMRI findings that (i) functional coupling within anxiety-processing brain regions (amygdala and anterior cingulate) reflected the integration of expectations with sensory inputs, and (ii) anxiety appeared to impair the updating of expectations via suppressed prediction error signals in the anterior cingulate, thus perpetuating negative expectancy effects. Regarding positive expectations, their integration with sensory inputs relied on the functional coupling within brain structures processing positive emotion and inhibiting threat responding (medial orbitofrontal cortex and hippocampus). In summary, different from treatment expectancy, pain modulation by stimulus expectancy emanates from emotion-modulated integration of beliefs with sensory evidence and inadequate belief updating.

Significance StatementAlthough evidence indicates that human pain experiences stem from the integration of prior beliefs with sensory evidence, the key factor that biases this integration process as pain perception is affected by stimulus expectancy remains unclear. Using fMRI, we examine participants’ emotional reactions when they expect and then perceive incoming painful stimuli. We find that the elicited anxiety during pain enhancement by expectations of increased pain influences the integration of expectations with sensory inputs and appears to impair the updating of expectations. By contrast, this integration mainly involves pleasant emotion provoked during pain attenuation by expectations of decreased pain. This work highlights the important role of emotions when human experience of pain is shaped by stimulus expectancy.

The limited market share and growth of Bumiputera entrepreneurs in domestic furniture and wood product industry in Malaysia remains a long-standing challenge. Therefore, a study to examine the market factors that contribute to the failure to thrive among Bumiputera entrepreneurs, registered with the Malaysian Timber Industry Board, was conducted. The results revealed that most of the respondents were micro- and small-sized enterprises, with sales focused on the domestic and contract markets. They were mostly producing sofa and kitchen cabinets, made to order, and sold in domestic markets within the vicinity. The respondents also indicated that the major challenges that impeded their ability to penetrate and capture market share include the limited production volume, lack of product diversity, limited government contract, and inter-ethnicity business collaboration. The Chi-square and Pearson Product Moment Correlation tests found that the significant challenges were only the limited production volume due to small company size, lack of product diversity, and the limited inter-ethnicity business collaboration among Bumiputera entrepreneurs. Therefore, policymakers should take heed that despite the many years of targeted and affirmative assistance to expand the domestic market share of Bumiputera entrepreneurs, the results remain poor, and inevitably, a new approach to Bumiputera entrepreneurs’ development must be adopted.

In this study, a mechanistic model was developed for the Elmendorf tear strength of paper based on the fundamental physics of the tear process . In the model, the tear strength was calculated as the sum of fibre fracture energy and fibre pull-out energy. The model also included statistical considerations, such as the distribution of fibre lengths. Through dimensional analysis, a “dimensionless tear index” was identified and was found to be a universal function of three dimensionless parameters. Using a bond strength obtained through non-linear regression analyses on a particular experimental data set, the model was validated with other sets of data. It was found that the model gave good quantitative predictions of tear strength of kraft papers without the need for adjustable fitting parameters. With a slight modification to account for the role of fines in the furnish, the model was also successfully applied to handsheets made from TMP pulps.
