Idiopathic pulmonary fibrosis in Soweto, South Africa: A descriptive study
Authors: Aitchison Wesley Mark , Van Blydenstein Sarah Alexandra , Wong Michelle
Published: March 2023

Objectives:

Idiopathic pulmonary fibrosis (IPF) is a specific form of age-related fibroproliferative interstitial pneumonia that is chronic, progressive, and carries a poor prognosis, with median survival of just 2.5–3.5 years from diagnosis. The exact etiology is unknown, but smoking is known to be risk factor. Symptoms and signs include progressive dyspnoea, cough, inspiratory “Velcro” crackles, and clubbing. At present, treatment options are limited; but include pulmonary rehabilitation, long-term domiciliary oxygen therapy, and the conditionally recommended pharmacological therapies pirfenidone and nintedanib. This study sought to describe the cohort of patients that attended the respiratory outpatient services at a tertiary-level hospital in South Africa during the period 2007– 2016. To the best of the authors’ knowledge, this is the first such descriptive study performed in Africa.

Materials and Methods:

This was a retrospective, descriptive, and record review, that included patients ≥18 years of age who fulfilled 2011 ATS/ERS/JRS/ALAT diagnostic criteria for IPF.

Results:

Data from 74 patients were used for analysis in this study, of which 60.8% were female. The mean age standard deviation was 64.4 (10.9) years and the majority (79.7%) were Black. Over half of the patients (40/74, 54.1%) were current or previous smokers, although there was no correlation between smoking history and age or baseline pulmonary function testing. All patients reported dyspnea, which was modified Medical Reseach Council (mMRC) Grade 3 or 4 in 80% of patients. High resolution computed tomography chest was reported as radiological usual interstitial pneumonia (UIP) in 72 patients (97.3%) and three patients underwent lung biopsy, all of which showed a UIP pattern. Fifty-eight patients (78.4%) had spirometry results available, with median forced vital capacity 67.3% of predicted; this was significantly higher in females. Median transfer factor of the lung for carbon monoxide was 39% predicted. Twenty-five patients (33.8%) received corticosteroids, of whom five (6.8%) received the prednisone-azathioprine-N-acetylcysteine regime. Three patients (4.1%) received nintedanib; two of whom showed slowing of decline in lung function, although no significant symptomatic improvement was reported. Mean duration of follow-up was 13.3 months, although females had significantly longer duration of follow-up than males.

Conclusion:

Despite a fairly small sample size and retrospective nature, this study contributes to the body of literature on IPF and highlights the need for additional studies in developing countries, particularly in Africa.
In vitro assessment of bracket adhesion post enamel conditioning with a novel etchant paste
Authors: Kadhim Hayder A. , Deb Sanjukta , Ibrahim Ali I.
Published: March 2023

Background: 37% phosphoric acid (PA) is the traditional enamel etching technique prior to bracket ‎adhesion, yet it has been implicated in numerous enamel injuries. The purpose of the current study was to create a calcium phosphate (CaP) etching paste in a ‎‎simplified capsule ‎formula that can underpin clinically ‎adequate bracket bond strength ‎without jeopardizing the ‎integrity of enamel upon ‎the debracketing procedure. Materials and Methods: micro-sized hydroxyapatite (HA) powder was mixed with 40% PA solution to prepare ‎experimental acidic CaP paste. Sixty human premolars were ‎assigned into two groups of 30 each. ‎Enamel conditioning was accomplished using 37% PA-gel‎ for control group and CaP paste for experimental group. Each group was further divided into two subgroups regarding the water storage (WS) period (24 h and 30 days). Shear bond strength (SBS) test conducted with examination of debonded surfaces for adhesive remnants and enamel damage using a digital microscope. Results: CaP paste produced significantly lower SBS values than PA (p < 0.01), yet sufficient for clinical use. PA etching caused often cracked enamel surfaces with excessive ‎retention of adhesive remnants (mainly ARI scores 2 and 3). Contrarily, enamel treated with the experimental CaP paste exhibited smooth, ‎unblemished surfaces mostly clean of adhesives residues (scores 0 and 1). Conclusion: a newly developed CaP paste in a capsule formula fosters ‎clinically adequate bracket ‎adhesion with a sustained bonding performance, allows a harmless bracket removal with ‎minimal or no adhesive residues on debonded surfaces; thus, it can be introduced as a suitable ‎alternative to PA‎.

Authors: Al-Kubaisi Mustafa W. , Al-Ghurabi Batool H. , Alkubaisy Waqar , ABDULLAH Nik N.
Published: March 2023

Background: Manuka honey (MH) is a mono-floral honey derived from the Manuka tree (Leptospermum scoparium). MH is a highly recognized for its non-peroxide antibacterial activities, which are mostly related to its unique methylglyoxal content (MGO) in MH. The beneficial phytochemicals in MH is directly related to their favorable health effects, which include wound healing, anticancer, antioxidant, and anti-inflammatory properties. Aims: The purpose of this study was to evaluate the effect of MH on pro-inflammatory cytokines (IL-8 and TNF-α) in patients with gingivitis and compare it with chlorhexidine (CHX) and distilled water (DW). Materials and Methods: This study was a randomized, double blinded, and parallel clinical trial. Forty-five young participants aged (20–40) years were randomly selected and allocated into three groups: MH, CHX, and DW mouthwash groups. Each participant was given a random bottle. Five milliliters each of honey-based mouthwash formulation, CHX mouthwashes (0.2%) and DW were used twice daily for 21 days. All the participants were examined twice, once on the zero day (base line) and once after 21 days. Before and after each participant's mouthwash use IL-8 and TNF-α were measured using enzyme-linked immunosorbent assay (ELISA). Results: The results revealed a drop in the level of interleukin-8 in the manuka honey group which was statistically significant, but the decrease in the same biomarker in the chlorhexidine group was insignificant statistically. TNF-α levels were found to be insignificantly reduced in both the MH and CHX groups (P˃0.05). The DW group, on the other hand, obtained the opposite outcome in both biomarkers. Conclusion: Mouthwash containing MH had an anti-inflammatory impact, indicating an immunomodulatory action. These signs may be encouraging and promising for the use of MH in treating gingivitis.

Most dental works require a diagnostic impression; alginate is contemplated as the most popular material used for this purpose. Titanium dioxide nanoparticles show evidence of antimicrobial activity in the recent era, for this purpose, this study aimed to evaluate the effect of adding Titanium dioxide nanoparticles on antimicrobial activity and surface detail reproduction of alginate impression material. Materials and methods: Titanium dioxide nanoparticles (purity = 99%, size= 20nm) was added to alginate at three different concentrations (2%, 3% and 5%). 84 samples were prepared in total. Samples were tested for antimicrobial activity using a disc diffusion test, and surface detail reproduction was done using (ISO 21563:2021). One-way ANOVA and independent sample t-test were used for data analysis through SPSS software. Results: for the antimicrobial test, inhibition zones for Streptococcus mutans and Candida albicans showed significant changes concerning the alteration in Titanium dioxide nanoparticle concentrations. The inhibition zone significantly increased with an increase in the percentage of Titanium dioxide nanoparticles. The mean of the inhibition zone for S. mutans was superior to C. albicans and the difference was statistically significant. Regarding surface detail reproduction, the control group, 2% and 3% groups manifested very similar results, only the group to which 5% of Titanium dioxide nanoparticles were added showed a decline in detail reproduction when compared to the other three groups. Conclusion: Within the limitation of this study, we can conclude that the antimicrobial activity against S mutans and C. albicans were significantly increased in modified groups, and this escalation was directly linked to the increase in Titanium dioxide nanoparticles concentration. In contrast, the surface detail reproduction was decreased when adding 5% Titanium dioxide nanoparticles to alginate.

The uses of mangrove fruit in food and beverages are rarely published in scientific papers.
One of the mangrove fruits used is Sonneratia caseolaris (berembang) or mangrove apple.
Each part of the mangrove apple is unique and believed to have many uses, such as the
sepal showing high antioxidants property. Some villagers eat the fruit as a vegetable
although it is not very well known. Ripe fruit could destroy intestinal parasites in
combating diarrhoea and semi-cooked fruit could cure cough. Few mangrove communities
in Malaysia can process S. caseolaris fruit into food products such as jams and syrups.
This research aimed to formulate mangrove apple (S. caseolaris) fruit puree and process it
into a refreshing drink which complied with consumer acceptance and a longer shelf-life.
Processing procedures for handling delicate S. caseolaris fruits and fruit puree
formulations were developed for commercialization to ensure sustainability of raw
material supply. Besides quality control and safety studies, the selection of ripe fruit with
the appropriate size along with processing of the starting material is important to increase
the quality of the product to be produced. Paste is the most suitable form to handle
because the fruit of S. caseolaris has a soft texture apart from the sour taste with its own
unique aroma. Ready-to-drink (RTD) fruit beverage product from S. caseolaris was
developed through the support of scientific value through chemical, bioactivity,
formulation, sensory, product safety and quality studies. Formula selection of RTD fruit
beverage product is also an important factor in meeting local demand, ensuring it comply
with customer requirements and are marketable. This study is expected to produce better
quality herbal products that meet standards and penetrate the global market.

Published: March 2023

Bromelain is well known as an anti-inflammatory compound derived from pineapple fruit
and stem extract. This study investigated bromelain content in raw pineapple with
different maturity indexes and also in pineapple juice drinks. Pineapple juice drink was
produced by mixing fresh juice with other ingredients, homogenized and pasteurized.
Bromelain content in raw and pineapple juice drinks was analyzed by using HPLC. The
total soluble solids and pH values were also determined in the pineapple juice drink. This
study also investigated the potential of pineapple juice drink as an anti-inflammatory drink
using carrageen-induced paw edema in rat model. Bromelain content in raw pineapple
showed that pineapple with index 4 contained significantly high (p<0.05) bromelain
compared to the others. The bromelain content in 200 mL of product is 106.33±0.14 mg/
ml and significantly (p<0.05) reduced by 50% after 12 months of storage. The drink has a
pH of 3.54 and 15°Brix. This study also revealed that bromelain in doses of 6.6 mL/kg
showed 15% inhibition of paw edema at the end of three hrs. These studies suggested that
bromelain does have anti-inflammatory properties which benefited athletes, especially for
recovery purposes.

The pineapple by-products possess desirable nutritional and physicochemical properties,
making it worthwhile to explore their use as a potential functional food element. The
study aimed to evaluate the proximate composition and the potential use of MD2
pineapple waste such as peel and pomace, as a growth medium for probiotic bacteria, such
as lactic acid bacteria and bifidobacterial. The pineapple pomace was obtained after the
pineapple pulp was pressed for the juice. Proximate analysis and the growth of lactic acid
bacteria were carried out on the dried and ground pomace. The proximate composition of
MD2 pineapple peel and pomace was attained in dry matter (g/100 g) including protein
(5.14 g, 6.34 g), total fat (1.14 g,1.09 g), total carbohydrate (85.07 g, 82.75 g) ash (2.42 g,
2.04 g), moisture (6.22 g, 7.79 g), crude fibre (17.4 g,19.39 g) and energy (371 kcal, 366
kcal). The growth performance of Lactobacillus paracasei and Lactobacillus acidophilus
in pineapple peel and pineapple pomace as an alternative bio ingredient in growth media
was significantly increased to log 2-log 3 at 72 hrs of incubation and was evidenced by the
lowered pH of the growth medium for each bacterium. The results showed that pineapple
waste is a good candidate as a bio ingredient to support the growth of L. paracasei and L.
acidophilus and has the potency to be a potential prebiotic for probiotic strains.

The food and beauty sectors are developing strategies to establish a link between nutrient
consumption and skin health, as nutraceuticals offer a promising treatment option for
some skin disorders such as hyperpigmentation and premature ageing. As a result, the
consumption of food ingredients and supplements claiming to lower the risk of developing
such skin problems is increasing. In this study, anti-tyrosinase potential of Aspergillus
oryzae-fermented rice by-product water extracts namely fermented broken rice (FBR),
brewers’ rice (FBrR), and rice bran (FRB) was assessed through in vitro study using
highly pigmented human melanoma MNT-1 cells. The fermented extracts were evaluated
for cytotoxicity, anti-tyrosinase activity using intracellular tyrosinase assay as well
as melanin content analysis. Their effect on the gene expression of three melanogenic
enzymes: tyrosinase (TYR), tyrosinase-related protein-1 (TRP-1) and tyrosinase-related
protein 2 (TRP-2) was also assessed by qPCR analysis. As a result, all extracts at tested
concentrations of 50 and 100 µg/mL have a low cytotoxicity effect. Together with the
positive control kojic acid, the FBR at both concentrations and the FRB at 50 µg/mL
significantly decreased intracellular tyrosinase activity. However, their melanin content
was not significantly reduced. The qPCR analysis indicated that FBR at 50 and 100 µg/
mL significantly reduced TYR gene expression by up to 71% and 61%, respectively. On
the other hand, FBR (100 µg/mL) increased TRP-1 gene expression, whilst FRB (100 µg/
mL) elevated both TRP-1 and TRP-2 gene expression. The positive control kojic acid
significantly reduced TYR, TRP-1 and TRP-2 gene expression. However, FBrR
demonstrated no significant effect in any of the analyses. Based on these findings, FBR
and FRB at 50 µg/mL possess anti-tyrosinase potential. However, further investigation is
needed to dissect deeper mechanisms underlying their potential as functional
bioingredients for nutraceutical or cosmeceutical applications.

The study aimed to investigate the effect of rosemary (Rosmarinus officinalis) extract on
the quality changes of fishballs from knife fish (Chitala chitala) and striped catfish byproduct (Pangasianodon hypophthalmus) during frozen storage. Fishballs were
supplemented with rosemary extracts at two concentrations of 13 mg/kg and 156 mg/kg.
The control treatment was the sample without extract. The products were steamed,
vacuum packed in PA bags and stored at a temperature from -18oC to -20oC. Sampling
was done at 0, 30, 60, 90, 120, 150 and 180 days of storage period for analysis of pH,
Total volatile base nitrogen (TVB-N), total viable bacteria count (TVC), pathogenic
bacteria, sensory properties, peroxide value (PV), Thiobarbituric acid reactive substances
(TBARs). Results showed that Escherichia coli and Salmonella spp. were absent in the
fishballs, reflecting the safety of products for consumers. Adding rosemary extract at 156
mg/kg in fishballs displayed more effectiveness in inhibiting the formation of lipid
oxidation and microbial growth when compared to the control sample during the frozen
storage. Based on the results of physicochemical and sensory quality, the supplementation
of rosemary extracts showed a significant promise for improving the quality of fishballs.
Fishballs from knife fish and striped catfish by-products could be maintained their sensory
properties and prolonged their shelf-life up to 180 days of frozen storage.

Published: March 2023

The number of people with diabetes mellitus (DM) at the global level and in Indonesia
continues to increase every year. Consumption of probiotic foods can improve symptoms
of metabolic syndrome in DM. The research objective was to determine the effect of
probiotic parboiled rice tape (fermented parboiled rice) on glucose, insulin, lipid profile,
number of lactic acid bacteria (LAB), pH, and short-chain fatty acids (SCFA) in diabetic
rats. The probiotic parboiled rice tape was made with the addition of Lactobacillus
plantarum Dad-13. The steamed rice was mixed with CMC as a thickener (2% of rice).
The mixture was cooled to room temperature (for 5-10 mins) before being further mixed
with the NKL yeast and powdered sugar (each of them was 0.2% of rice). Then, the
mixture was inoculated with 1×108 CFU/g of L. plantarum Dad-13 and fermented at room
temperature for 48 hrs. The tape was then given to diabetic Wistar rats in the form of a
wet tape product at 1.8 g per head per day. Treatment diets were given for 28 days to 4
groups of rats, namely SFHR (Standard Feed in Healthy Rats), SFDR (Standard Feed in
Diabetic Rats), PTDR (Probiotic rice Tape in Diabetic Rats), PPTDR (Probiotic Parboiled
rice Tape in Diabetic Rats). The data obtained were analyzed statistically using one-way
ANOVA. The results showed that, in the PTDR and PPTDR groups, their glucose levels
decreased significantly (p<0.05) from 257.47 mg/dL to 155.78 mg/dL (39.49%), and from
260.32 mg/dL to 109.88 mg/dL (57.79%), respectively. For insulin levels, there was a
significant increase (p<0.05) from 418.35 ug/dL to 485.00 ug/dL (15.86%) and from
414.84 ug/dL to 532.85 ug/dL (26.52%) in the PTDR and PPTDR groups respectively. In
the PPTDR group, cholesterol, triglyceride, and LDL levels decreased significantly
(p<0.05) by 37.65%, 34.50%, and 59.29%, respectively, and the percentage of reduction
was greater than the other diet groups. HDL levels increased significantly (p<0.05) from
24.94 mg/dL to 67.64 mg/dL (171.21%) in the PPTDR group. Meanwhile, the amount of
LAB, levels of SCFA (acetic acid, propionate and butyrate), and pH in rats - faeces did
not show any significant (p>0.05) changes. The provision of probiotic tape improved the
metabolic synthesis of diabetic rats and treatment with PPTDR was better than that of
PTDR.

Published: March 2023

This study aimed to analyze and discuss the influence of knowledge, religiosity, and attitude on well-educated Muslim women Millenials’ interests in buying halal cosmetics in a state with a Muslim majority. The judgemental sampling technique was applied to take samples using an online questionnaire. Two hundred twenty-three respondents were collected, yet, only 210 well-educated Muslim women with minimum ages of 21 years old could participate. Data is analyzed using path analysis to see the correlation among variables. The result found that well-educated Muslim women Millenials had a positive interest in buying halal cosmetics. Besides any information about halal cosmetics products, their belief level on their religion significantly affected their attitude and interests in buying. It found that most of the respondents knew halal cosmetics from the internet through open questions. Although a state with a Muslim majority becomes the research location, many people still used cosmetics with no halal certificates. Therefore, marketers should advertise their halal products, mainly through digital media. This study focused on consumers' attitudes toward rapid-growth cosmetics products in Indonesia, and it referred to halal cosmetics. Also, this study focused on the millennials generation who had an age group with the most number. Therefore, it was necessary to put this issue into a marketing discussion.
No Referendum, No Election Campaign: How Radio Biafra Internet Broadcasting Mobilized IPOB Worldwide during the 2019 Nigerian Election
Authors: Nwafor Gideon
Published: March 2023

In the buildup of 2019 general election in Nigeria, there were tensions in the Southeastern part of the country over the clamours for election boycott campaign initiated by the leader of the Indigenous People of Biafra (IPOB), Mazi Nnamdi Kanu, requesting that a referendum should hold in the region for the purpose of secession rather than conduct an election in the area. This drew critical attention nationwide and in diaspora as some rose to condemn the call while some supported the move. Few days to the election, the polity was heated up as to whether the Southeasterners will heed the clarion call to boycott the election or not with the IPOB foot soldiers on ground driving the campaign and threating mayhem to anyone who come out to vote until the “Supreme Leader” of IPOB called off the election boycott 24 hours to the election and there was total compliance and suspension of the campaign in the region. This could not have been possible without the effectiveness of Radio Biafra Internet broadcasting. How this Internet radio station was effective in the mobilization of members of IPOB to drive the “No Referendum, No Election” campaign is the focus of this study.  Anchored on Technological Determinism theory, survey method was used to carry out the study with a population of 803,416 and a sample size of 382 listeners in Anambra and Abia States as respondents drawn using Krejcie and Morgan Sample Size Determination Table. The findings revealed that people were highly exposed to Radio Biafra No Referendum; No Election Campaign through Internet broadcasting on Facebook, Word of Mouth and Radio Biafra Terrestrial Broadcasting and this influenced their attitude toward 2019 election resulting to voter apathy in the area. Based on the findings, the researchers therefore, recommend that Radio Biafra should engage their digital broadcasting for national cohesion and integration rather than preach the message of secession disintegration

Participatory Budgeting in Indonesia: from the Policy Innovation to the Democracy Innovation
Authors: Affandi Mochamad Arif , Marijan Kacung , Windyastuti Dwi
Published: March 2023

Community participation in the government budgeting process provides opportunities for wider and deeper public participation. This paper uses a systematic literature review method with a meta-synthetic approach that aims to examine the practice of participatory budgeting (PB) in Indonesia by comparing PB programs in the early reform era with PB programs in the reform era. The results show that the PB model in the early era of World Bank-sponsored reforms such as the Musrenbang (PNPM and KDP) is a technocratic administrative policy innovation because it has standard rules, innovation comes from the government and the community becomes the object of government policy. In addition, this study also finds that Prodamas indirectly strengthens Musrenbang because of its participation at the RT level. People at the lowest level are encouraged to participate more. Therefore, the researcher hopes that Regional Regulations have greater power.

Understanding Student Attitudes toward Delivering English Oral Presentations
Authors: Ho Han , Nguyen Long , Dang Nhon , Nguyen Hong X.
Published: March 2023

Delivering English oral presentations is deemed a prevalent activity of language learning in the university setting. Given that students’ attitudes have a substantial impact on the outcomes of language learning through delivering oral presentations, this study examined the attitudes of 153 third- and fourth-year students enrolled in an English major at the Department of Foreign Languages at a university in Southern Vietnam toward delivering presentations in English. The study has also focused on investigating what factors affect their attitudes toward the presentations. The study used quantitative and qualitative methods in gathering and analyzing the data. The findings revealed that most of the students had positive attitudes toward the presentations although they encountered some impediments in the course of the delivery. Student language proficiency, learning styles, and factors related to teachers and audience are the key factors that are instrumental in students’ attitudes toward delivering their oral presentations; familiarity with the topic and public speaking anxiety also affected their presentations. Pedagogical implications were suggested to most benefit students of different proficiency levels and learning styles with regard to English oral presentations.
Writing Motivation in the Web of Science and Scopus Databases: A Scientometrics Perspective in CiteSpace
Authors: Wang Wenxuan , Asniza Ishak Nor
Published: March 2023

In education, writing motivation is a major concern since high levels of motivation generally contribute to effective writing. This study selected 148 studies from the Web of Science and Scopus on writing motivation in the early 21st century (2001–2022). Accordingly, using the Scientometric perspective in CiteSpace, the current research state, development trends, and possible future paths in writing motivation are systematically analysed. The analysis of publications includes quantity and trends, citation frequency, and keyword co-occurrence. Findings reveal that (1) since 2011, the number of publications on writing motivation has increased annually, showing a steady upward trend. (2) Highly cited articles on writing motivation focus on the following research perspectives: motivation theory, writing performance, gender, grade level, and writing instructional methods. Furthermore, Pajares and the United States emerged as outstanding contributors and nations, respectively. (3) The majority of research hotspots are devoted to educational research, psychology, and linguistics. (4) The writing motivation research process can be separated into three distinct phases: the emerging phase, the stagnation phase, and the rapid development phase. Writing motivation is a promising research field that will require researchers and practitioners to investigate educational methodologies continuously, select large samples to study the scope, and implement ideas. By doing so, these constructive methods will benefit students’ writing and meet future work requirements.
Interests, Barriers, Stress, and Resilience of High School Students: A Caring Christian Religious Education Teacher
Authors: Sitepu Elisabeth , Hasugian Johanes Waldes , Simamora May Rauli
Published: March 2023

This study identified the interests and barriers felt by students as an illustration of the concern of Christian Religious Education (CRE) teachers. This study aims to describe the level of stress and resilience of students, their preferred coping strategy, and the correlation of stress with student resilience. This research uses a quantitative approach with a nonexperimental design. A total of 147 respondents was sampled from the 700 teenage students population. The age range of students is 16 – 18. A survey questionnaire was used to investigate the stress and resilience scale of students, namely the Perceived Stress Scale which consists of 10 items (PSS-10), and the Connor-Davidson Resilience Scale which consists of 10 items (CDRS-10). The results from the descriptive analysis show that very few students have an interest in learning CRE and the highest barrier is self-confidence. The results from the descriptive analysis show that the level of stress that students feel is mostly in the middle category and the low category. The level of student resilience is mostly in the medium and high categories. The results of the correlation analysis show that stress is related to resilience where the direction of the correlationis negative. It means that the students who scored higher on PSS-10 is more likely to have difficulty or lower survival capacity (low endurance score). Therefore, to reduce the impact of stress so that the students have high resilience, coping strategy efforts by CRE teachers must be carried out with high concern, so that students can focus on interests and can face various barriers.
TVMM: an R package for testing hypothesis on mean vectors
Authors: Alves Henrique José de Paula , Furtado Ferreira Daniel , Deivide de Oliveira Batista Ben
Published: March 2023

TThe Multivariate Tests for the Vector of Means (TVMM) package has six functions: T2O function, which computes Hotelling original’s T² test; T2Boot function, which computes the parametric bootstrap version of the original T2 test; T2RobustBoot function, which computes the robust parametric bootstrapversion of the T2Boot test; LRTTrace function, which computes the asymptotic version of the likelihood ratio test (LRT) using the trace operator; LRTTBoot function, which computes the parametric bootstrap version of the LRTTrace and the LRTTRBoot, which computes the robust version of the LRTTBoot. The alternative test versions of the LRT have the advantage of being valid for high-dimensional data. We describe the methods and illustrate the use of the TVMM package with real data on soil properties.
Sensorial analysis of categorized data of special coffee to identify similar crop seasons pairs using Kappa

This paper presents the proposal of a statistical method to analyse dependent agreement data with categorical ordinal responses for a longitudinal study in sensorial analysis of special coffee. The assessment of sensory attributes of special coffees were carried out by certified raters using a continuous scale of grades. The approach aimed to applying data categorization methods commonly used in machine learning which generated not only a concise summary of continuous attributes to describe the data but also allowed to maximize the agreement grades in a longitudinal study. A previous analysis was carried out to identify the similarity of grades in all sample unities. The categorization allowed the construction of marginal models for all distinct pairs time observed in the longitudinal study for modeling the concordance correlationskappa. It also enabled to conclude that samples of harvests related to yellow grain fruits have similar sensorial characteristics. Higher altitudes are significantly favorable to obtain samples with similar sensorial characteristics identifying the set of covariates which contributed either in positive or negative way while estimating kappa.

Published: March 2023

This study aimed to develop a scale to measure the harassment experienced by women in multiplayer online games. The study sample consisted of 324 Brazilian female players aged 18 to 44 years recruited from an online survey. Item Response Theory (IRT), particularly the graded response model, was used to evaluate the performance of the items proposed to measure the cited harassment. Moreover, linear regression was used to investigate the association between some women's characteristics and the scale. The results showed that the proposed scale is a nine-item unidimensional psychometric instrument suitable for measuring and better understanding the harassment experienced by women in online gaming spaces. In addition, the association analysis evidenced a high level of harassment among women who reported playing using female nicknames and playing more than three types of games. Finally, most of those who reported a preference for playing with female players had already experienced a high level of harassment.
Robust local quantile regression for reference curves
Authors: M.S.Santos Gianni , D. S de André Carmen , M. Singer Julio
Published: March 2023

We propose two non-parametric methods to construct locally fitted quantile reference curves that are robust with respect to outliers in the predictor variable. The first includes a weighting procedure and the second, the detection and subsequent elimination of outlying predictor variable values before the local fitting process. The reference curves fitted by the proposed methods generate quantile limits that are less affected in regions with a low frequency of the predictor variable values. The proposed procedures are used to fit reference curves to data extracted from a study conducted at the Heart Institute of the University of São Paulo Medical School.
Multistate model in the behavioral study of the parasitoid Telenomus podisi for biological soybean control

Published: March 2023

Biological pest control through the use of wasps are sustainable ways of protecting plants and, consequently, agricultural production. In this context, an entomological experiment is motivated, in which the forraging and reproductive behaviors of the parasitoid Telenomus podisi were qualified over time, considering non parasitized (sp0) and parasitized (sp1) of the brown stink bug, Euschistus heros. The experiment features a longitudinal study of continuous time with variable nominal qualitative response, grouped into four mutually exclusive categories (flying-walking, drumming, oviposition and marking). Continuous time transition models, also known as multistate models, are a viable alternative for analyzing data with these characteristics. Therefore, this class of models was considered in this work to study the behavior of the parasitoid, through the average length of stay in each of the response categories, as well as their preference probabilities. As a result, there was a significant effect of the treatment of host eggs (non parasitized or previously parasitized). When having contact with previously parasitized eggs, the female parasitoid T. podisi has preference for the categories of movement which are flying-walking and drumming. In contrast, when in contact with non parasitized eggs, the female T. podisi has a preference for ovipositionand marking. The applied methodology proved to be adequate for this typical experimental situation in entomological studies associated with the description of the behavior of a parasitoid.

Published: March 2023

Objetiva-se compreender as percepções de professoras dos anos iniciais, em Fortaleza-CE, sobre a formação em contexto. Trata-se de uma pesquisa qualitativa, do tipo estudo de caso, com entrevista semiestruturada junto a sete professoras de uma escola pública municipal, com dados examinados à luz da análise de conteúdo. Os resultados evidenciaram que é ofertada uma formação continuada sob uma perspectiva crítica e reflexiva, mas que as professoras não constroem essa formação coletivamente. Além disso, os temas da formação não são definidos por professores e coordenadores pedagógicos, mas pela Secretaria de Educação.
