Authors: Liu Qian , Xu Ting , Qi Shanzhong
Published: October 2023

Household adaption to natural hazards has been critical in disaster prevention and mitigation in disaster-prone regions. However, the adaption of urban household to natural hazards is not yet fully understood, especially in the subtropical forested region of Southeast China. In this study, we investigated the urban household adaption to natural hazards in the forested region of southeastern China by using a multinomial logistic regression model to analyze 763 urban household questionnaire responses from 6 districts in Hangzhou City, Zhejiang province. The results indicated that (1) from high to low, the top 6 natural hazards deeply concerned by urban household of Hangzhou City were typhoon, rainstorm, lightning, flood, low temperature disaster and snow disaster and (2) gender, length of family residence, disaster awareness and household satisfaction all significantly influenced the urban household adaption to natural hazards. This study suggested that Government should improve channels for disaster publicity, strengthen community management and promote social emergency construction in future decades.
Heavenly-born characters in the published myths of Verbitsky: the words Tyanar and Tangara
Authors: Pashtakova T. N.
Published: October 2023

This article discusses Altai myths with the mention of the name of the character Tyanar,published in the work “Altai aliens” by Vasily Verbitsky. However, in order to clarify the primordial characterof the Tyanar in the Altai myths, we find out the history of the recording of myths by Verbitsky, and analyzethe myths about celestial characters. For the same purpose, we find out other Altai mythological storiesabout the messengers of the heavenly world in the Altai cosmogony and compare them with the Yakut storiesin which the character Tanara is present. The article traces the cult of Heaven in the Sakha (Yakutia) in termsof comparative and shamanic ritual with the poetry of Altai, Khakassia, Tuva and Buryat. We analyzedsimilar terms for the concept of Heaven and destinations that symbolize the worship of heaven. The authorbelieves that the cult of Heaven in the Sakha (Yakut) kept the general typological features. It manifests itselfin ritual and ceremonial complex of Ysyakh festival. Sky personified Urduk Ajyylar ‘Supreme Deity’, onpresentation of the Yakuts, living in different layers of heaven.
30 anos da Associação Portuguesa de Linguística ou A entrada na vida adulta
Authors: Costa João
Published: October 2023

Mais do que começar por agradecer o convite que me foi feito para fazer esta evocação dos 30 anos da nossa Associação Portuguesa de Linguística, quero repetir à frente de todos o que disse ao João Veloso, quando ele me fez este gentil convite: “olha que eu já entrei na história a meio... Não vivi a história toda! Só comecei a pôr águas em mesas em 1990”. Ele disse-me que a Direção pretendia exatamente que esta evocação fosse feita por alguém que não tivesse estado envolvido desde o início. Por me considerar um linguista que muito tem beneficiado do que foi e é a APL, resolvi aceitar com gosto o convite para estar aqui hoje, propondo uma reflexão que é necessariamente pessoal e que pecará, certamente, por insuficiente e por não fazer justiça a tudo o que esta Associação tem dado a tantos investigadores.
Leitura em voz alta, movimentos oculares e prosódia. Integração de informação sintática e discursiva
Authors: Falé Isabel , Costa Armanda , Paula Luegi
Published: October 2023

This study aims to connect data from ocular movements and reading aloud to the syntactic and discursive properties of texts, in order to understand integrative cognitive processes during reading for understanding. Assuming that in reading aloud there is a close interaction between syntax structure and speech prosody, we collected eyetracking and speech production data from 17 female EP speakers during the reading of two texts. Eye movements and reading speech produced simultaneously were analyzed and our results show that the eyes and the voice are both responsive to text complexity and to syntactic and discursive selected loci, as key points of information integration.
A organização retórica de um artigo de opinião sob o enfoque funcionalista
Authors: Gessélda Somavilla Farencena
Published: October 2023

This paper aims to analyze the argumentative rhetoric organizing an opinion article and its linguistic realization from the application of analysis categories of the Rhetoric Structure Theory - RST (Mann; Thompson, 1985; Taboada; Mann, 2006), the Systemic Functional Grammar (Halliday; Matthiessen, 2004, 2014) and the Appraisal System (Martin; White, 2005). The macro-structural organization is constituted by the Block I, the title, which functions as Block II’ satellite, corresponding to the core. Block II is made up of portions 02 to 04, wherein the portion equivalent to 02 Claim; the portion 03, the Evidence; the portion 04, the Appeal.
Clíticos e objetos nulos na aquisição de português L2
Authors: Fiéis Alexandra , Madeira Ana
Published: October 2023

This study investigates whether the acquisition of clitics in L2 Portuguese is characterised by high rates of omission, as has been observed in L1 acquisition. On the basis of production and comprehension data from three intermediate learner groups (speakers of English, Spanish and Chinese), we conclude that there is no evidence for a generalised omission strategy. Omission in L2 Portuguese appears to be determined both by properties of the learners’ L1 and by specific properties of the grammar of Portuguese, and results from an overgeneralization of the null object construction, similarly to what has been argued for L1 Portuguese.
Estratégias de anteposição de PPs em construções-Q no português de São Tomé e no português europeu
Authors: Gonçalves Rita
Published: October 2023

This paper aims to compare the strategies of PP-fronting in Santomean Portuguese (STP) and European Portuguese (EP) in different syntactic constructions, namely relative clauses, questions, clefts and pseudoclefts, from the perspective of the Derivational Complexity Hypothesis (Jakubowicz, 2004, 2005; Soares 2006). Specifically, we will discuss to what extent the derivational complexity metric proposed can explain the occurrence of pied-piping and chopping in those constructions. We will further analyze the role of (di)transitivization tendency in STP as well as the dichotomy oral-written discourse in both varieties. Data from oral corpus as well as an elicitation task will be considered.

Published: October 2023

This paper aims at outlining some aspects of biolinguistics — the study of the biological bases of language. After a brief introduction, some considerations are made on the reasons for the lack of attention given to this approach until very recently, as well as some reasons for its reemergence, which is now underway.
Parâmetros para análise de narrativas orais em crianças com e sem perturbação da linguagem expressiva
Authors: Paula Monteiro  , Costa Armanda , Baptista Adriana
Published: October 2023

Analysis of children’s productions of oral narratives is a highly effective research tool that allows examiners to document children’s productive vocabulary and grammar (using microstructural analyses) as well as children’s text level narrative organization skills (using macrostructural analyses). In this study we used the Narrative Scoring Scheme and the Speech Rate and Fluency in Children and Adolescents to analyse the productions of oral narratives of children with and without language disorders. The results showed language developmental effects. Children with language disorders have difficulties in the use of macro and microstructural features and lower speech fluency score.

Published: October 2023

In this article, we present COPLE2, a new corpus of Portuguese FL/L2, which encompasses written and spoken data produced by foreign learners of Portuguese at the University of Lisbon. Over the past few years we are seeing a substantial growth in the area of learner corpus research applied to other languages besides English. Our aim is to enhance the learning data of Portuguese, a less commonly taught language. We believe that COPLE2 will constitute a good resource for teachers and researchers, since it will provide empirical data to: (i) identify general errors in the learning of Portuguese L2; (ii) develop textbooks and other teaching material targeting specific groups of students; (iii) implement teacher training material by taking into account the analysis of the corrections of the teachers. We will briefly describe the work in progress regarding the constitution and linguistic annotation of this corpus.
Análise sintática dos objetos cognatos no quadro teórico da Morfologia Distribuída
Authors: Morgado Choupina Celda
Published: October 2023

Cognate constructions form a very extended family and they exist in different world languages. In this paper, we analyze Cognate Object’s types and subtypes in European Portuguese, using the framework of Distributed Morphology. From a theoretical point of view, the assumptions of this model allow us to explain that verbs with different syntactic-semantic properties (sonhar [to dream], tossir [to cough], cantar [to sing] and dormir [to sleep]) may occur in structures with a cognate object in verbal adjacency, typically in a direct object position. Movement by copy and co-indexing prove to be central mechanisms to the licensing of the cognate object constructions with an eventive interpretation, as in tossir-tosse [to cough-cough].
Supramolecular Construction of a Highly Elongated π-Conjugated Structure in the Solid State: Metal-Free Click Reaction Guided by C-H Hydrogen Bonding
Authors: Yelgaonkar Shweta , Li Changan , Charles Amy , MacGillivray Leonard
Published: October 2023

A planned topochemical azide-alkyne cycloaddition is developed in the organic solid state to generate a highly elongated π-conjugated 1,2,3-triazole by a metal-free click reaction. The triazole is generated using a binary cocrystal composed of stilbenes that are covalently adjoined in a single-crystal-to-single-crystal transformation. The click reaction is accompanied by a large-scale structural reorganization involving procession-like movements of 1D stacked columns into a 2D layered structure. The formation of the layered structure is guided by newly formed triazoles self-assembling via C-H···N hydrogen bonding.

Published: October 2023

Amyloid fibrils of proteins such as α-synuclein are a hallmark of neurodegenerative diseases and much research has focused on their kinetics and mechanisms of formation. The question as to the thermodynamic stability of such structures has received much less attention. Here, we present a novel experimental method to quantify amyloid fibril stability based on chemical depolymerisation and Taylor dispersion analysis. The relative concentrations of fibrils and monomer at equilibrium are determined through an in situ separation of these species through Taylor dispersion in laminar flow inside a microfluidic capillary. This method is highly sample economical, using much less than a microliter of sample per data point and its only requirement is the presence of aromatic residues because of its label-free nature. Using this method, we investigate the differences in thermodynamic stability between different fibril polymorphs of α-synuclein and quantify these differences for the first time. Importantly, we show that fibril formation can be under kinetic or thermodynamic control and that a change in solution conditions can both stabilise and destabilise amyloid fibrils. Taken together, our results establish the thermodynamic stability as a well-defined and key parameter that can contribute towards a better understanding of the physiological roles of amyloid fibril polymorphism.

Published: October 2023

The antibacterial activity of silver nanoparticles has been well-researched throughout the years, and massive data has been generated describing a specific nanoparticle sample and its antibacterial activity by performing laboratory experiments; however, none have utilized this data to create a means of predicting the antibacterial activity. In this paper, we developed a polynomial equation using machine learning that predicts the antibacterial activity of silver nanoparticles against S. aureus and E. coli. Only studies featuring spherical silver nanoparticles without any surface modifications that may enhance the antibacterial activity were considered, and the studies must test the antibacterial activity in terms of the number of bacterial colonies left after treatment to calculate the efficiency. The equation takes the size and amount of the nanoparticles in a particular sample as inputs and predicts its antibacterial activity in terms of the percentage of bacterial colonies left after treatment. The equation was validated for its accuracy and was found to accurately predict the antibacterial activity based on the values of the relevant features. The study is the first of its kind and contributes to the field by reducing the effort and resource consumption in laboratories and providing a simple and efficient means of predicting antibacterial activity.

Published: October 2023

El cadmio es un metal pesado, que tiene un papel toxico y representa una amenaza a la cadena trófico, por lo que la necesidad de nuevas tecnologías de monitoreo en detección, cuantificación y reducción de este metal pesado es apremiante. En el estudio, se realizaron pruebas de acumulación de cadmio en tejidos vegetales de plántulas de espinaca como especie de interés en actividades de fitorremediación. En la metodología utilizada se realizaron análisis de concentración de cadmio mediante espectrometría de masas de plasma ICP-MS. También se realizaron caracterizaciones ópticas y microscopía electrónica para obtener información detallada sobre las superficies de la raíz, tallo y hoja de la espinaca. Para el diseño del filtro, se propone la idea de obtener membranas a partir de tejidos vegetales para retención de metales pesados teniendo en cuenta procesos de acumulación de metales de interés en plantas. En el estudio se destaca los resultados de concentración en el tejido radicular de la espinaca para retención de cadmio y se resalta su potencial aplicación en el diseño y desarrollo de filtros vegetales. Sin embargo, se requiere de más investigaciones y validaciones para determinar la eficiencia y viabilidad de este material en la remoción de cadmio en diferentes contextos. Este trabajo se encamina a tareas de saneamiento mediante la retención de cadmio en muestras de aguas de riego, dado que es uno de los metales de mayor reporte por parte de la comunidad académica, por lo cual se evidencia una necesidad de investigación en nuevas tecnologías de detección de Cd menos invasivas, de mayor selectiva y de bajo costo.

Exploring the impact of grief on firefighters due to highly stressful or traumatic job situations
Authors: Nicole Marie Juarez , Joseph Ramos Villarreal , Elizabeth A. Wardle
Published: October 2023

Firefighters regularly deal with highly stressful and traumatic employment situations. However, a majority of the fire departments lack appropriate counseling services to help employees. In this study, the researcher surveyed firefighters in a South Texas community to discover the extent of the effects of highly stressful or traumatic job situations. The results indicated that the years of active firefighting experience determines level of acceptance of coping techniques and counseling methods. The higher number of active experience correlates with a higher rate of exposure to traumatic events leading towards the willingness to seek help. Most active firefighters would not seek out private counseling to address job related stress, anxiety, or grief. They were, however, open-minded to the idea of participating in group or individual therapy sessions if provided to the department. The local firefighting departments should consider providing necessary counseling services for employees to help cope with traumatic situations or job related stress, anxiety, or grief.

Authors: R. Nurul AIn , A.B. Siti Roha , Andoyo R. , M.S. Adi
Published: October 2023

Date palm sap is a clear sweet drink originating from the date palm tree, which is
potentially fermented into toddy. Beer and wine are a product of alcoholic fermentation of
malted grain and grape juice, respectively. This study aimed to optimize and validate the
method for the determination of ethanol, methanol, isopropanol, and tert-butanol in date
palm sap, beer, and wine using headspace-gas chromatography with a flame ionization
detector. The volume of sample, oven temperature, and equilibrium time for headspace
conditions were optimized at 2.5 mL, 102°C, and 31.7 mins, respectively, using the
response surface methodology. The study showed that the model is satisfactory with no
significant lack of fit (p>0.05). This method was specific with no overlapping peaks and
good chromatography separation for all analytes. The limit of detection and limit of
quantification was 0.01% (v/v) and 0.03% (v/v) for ethanol, 0.3 mg/L and 1.0 mg/L for
methanol, and 0.1 mg/L and 0.5 mg/L for both isopropanol and tert-butanol, respectively.
All analytes demonstrated good linearity with correlation coefficients (R2
) greater than
0.990, good recovery (87.8–114.1%), and acceptable precision for repeatability (0.7–
4.3%) and reproducibility (1.5–10.2%). This study suggested that the method was
successfully optimized and validated as an appropriate technique for verifying alcohols in
palm saps and alcoholic beverages for the surveillance of Halal status and inedible alcohol
contamination, respectively.
Effect of chitosan addition on proximate composition, antioxidant activity, and
sensory acceptance of biscuits containing red and purple roselle extract
Authors: Kusnadi  , Purgiyanti  , Kumoro A.C. , Legowo A.M.
Published: October 2023

The purpose of this research was to produce biscuits containing red and purple roselle
extract with the addition of chitosan to improve the biscuits’ proximate composition, total
phenolic, antioxidant activity, and sensory acceptance. The research used a completely
randomized design with seven factors containing red and purple roselle extract, and
chitosan, respectively; C1 (0:0:1)%; C2 (10:0:0)%; C3(0:10:0) %; F1(4:6:1)%; F2
(6:4:1)%; F3(4:6:2)%; and F4(6:4:2)%. Proximate composition (moisture, protein, fat,
carbohydrate, ash and fibre) was determined using standard methods. The total phenolic
content of roselle extract biscuits was measured using the Folin-Ciocalteau method,
whereas the determination of antioxidant activity was carried out by applying the 2,2-
Diphenylpicrylhydrazyl (DPPH) method. The proximate analysis of the biscuits produced
high moisture content ranging from 3.25 to 3.94% W/W, protein content from 6.68 to
7.43% W/W, and fat content (19.13-19.74% W/W). The ash content varied from 1.62 to
1.72% W/W, fibre content ranged from 3.32 to 5.06% W/W, and carbohydrate contents
were 62.50-65.40% W/W. The concentration of 1% chitosan in the biscuit formulation
was also more effective in increasing the phenolic content and antioxidant activity (IC50),
respectively 3.36 mg/100 g and 71.81 ppm in the F1 biscuits samples (red roselle 4% and
purple 6%). Similarly, in F1 with the addition of 1% chitosan to sample biscuits
containing red (4%) and purple (6%) roselle extract, the panellists received good
acceptance of the aroma, colour, texture, taste, and overall biscuits made. Biscuits
containing 6% purple roselle and 1% chitosan in the formulation could be provided with a
significant contribution to increasing total phenol, antioxidant activity, and sensory
acceptance compared to the others. Therefore, roselle extract and chitosan can be used as
additional biscuit supplements that can increase nutritional content and antioxidant
activity.

Trichophyton rubrum is type of fungus that most often causes superficial fungal infections. Development of herbal ingredients as antifungal therapy is carried out to find alternative therapies for fungal infections. Bitter melon contains various compounds that have potential to be used as antifungals, including flavonoids and saponins. The aim of this study was to determine the effect of bitter melon extract (Momordica charantia L) on the growth of Trichopyton rubrum. This study used bitter melon extract at concentrations of 5%, 25%, 50%, 75% and 100%. Ketoconazole concentrations of 2% was used as a positive control. Pure cultures of Trichopyton rubrum were diluted using physiological NaCl. Fungal growth was observed microscopically and macroscopically. Results showed that Trichopyton rubrum grew at a concentration of 5% while at concentrations of 25%, 50%, 75% and 100% there was no Trichopyton rubrum growth. Bitter melon extract at a concentration of 25% had similar effect as ketoconazole 2%. Conclusion Bitter melon extract at concentrations of 25%, 50%, 75% and 100% had a similar effect to 2% ketoconazole in inhibiting the growth of Tricophyton rubrum.

Background:  Obesity is a complex disease that is generally accompanied by insulin resistance and increased oxidative stress and the expression of inflammatory markers that contribute to the accumulation of body fat mass. Lemons contain high levels of flavonoids and essential oils so that they have the potential to control appetite and play a role in fat breakdown. Purpose: to determine the effect of Citrus amblycarpa Hass extract on weight loss of rats fed a high-fat diet.Objective: Rattus novergicus Wistar strain aged 2-3 months and randomly divided into 6 groupsMethods: The dried Citrus amblycarpa Hass peel was extracted by maceration method with 70% ethanol as solvent. Variations in the dose of Citrus amblycarpa Hass peel extract given were 200, 300 and 400 mg/kg BW. There were 6 groups of treated rats with 30 rats total sample. The weight of the mice from each treatment group was measured for 6 weeks and then the average body weight of each group was analyzed using Kruskall Wallis with the Mann-Whitney further test.Results: The data showed that administration of Citrus amblycarpa Hass peel extract had a significant effect on weight loss of Wistar rats fed a high-fat diet with p= 0.00 (p <0.05). The average body weight of the 300 mg/kg BW and 400 mg/kg BW extract treated rats was significantly different from the control group that was not given the C. amblycarpa Hass peel extract, but the average body weight in the 200 mg/kg BW dose group did not show a significant difference.Conclusion: There is an effect of C. amblycarpa Hass peel extract in reducing the body weight of Wistar rats fed a high-fat diet significantly at doses of 300 mg/kg BW and 400 mg/kg BW.

Published: October 2023

Background:  LMP-1 and p16 expression are potential biomarkers for nasopharyngeal prognostic factors. EBV interferes with intracellular signaling processes related to cell cycle regulation and LMP-1, inactivating p16 expression and increasing cell proliferation. LMP-1 has been also reported to remove the promoter of p16 via methylation and inactivation of the p16 gene leads to uncontrolled proliferation of cell tumors.Objective: To analyze the association between LMP-1 and p16 expression with prognostic factors of nasopharyngeal carcinoma.Methods: This is a cross-sectional design analyzed that LMP-1 and p16 expression based on immunostaining of nasopharyngeal carcinoma. The patient clinical data used as prognostic factors are histopathological type, quality of life, TNM, and tumor stage. Statistical analysis used chi-square and spearman correlation.Results: Of the 61 patients, 49 were non-keratinizing carcinoma, undifferentiated type (80,3%). About 54 (88.5%) of the 61 samples are LMP-1 positive, 47 of which were non-keratinizing carcinoma. We figured out the significant association between the p16 expression with lymph node involvement (p=0.026) and staging (p = 0.196) in nasopharyngeal carcinoma.  No correlation between LMP and p16 expression (p=0,134) (r=-0,194).Conclusion: p16 overexpression is associated with lymph node involvement and advanced stage in nasopharyngeal carcinoma

Interpersonal communication competence plays a crucial part in the educational interaction space, as it directly impacts the behaviour of students who require a straightforward communication flow. This study aims to analyse the integration of project-based learning (PjBL) in preparing students' interpersonal communication skills in speaking courses in Indonesia, the proficiency of students' interpersonal communication skills, and the challenges of achieving them. The design of this study was a cross-sectional survey conducted in May 2023, involving 315 college students from six English Study Programmes at six universities across three provinces. Data were collected using questionnaires and interviews and were then analysed with the assistance of Jeffreys Amazing Statistics Program. The total number of interviewees was 60, with 10 from each university. The data indicate that the interpersonal communication profiles of the 315 respondents fell into the Medium category (mean = 3.26), and the most common obstacle (mean = 4.6) in achieving interpersonal communication skills on a speaking course is a difficult-to-understand speech partner's accent. This finding has implications for college students, as these interpersonal communication skills should be strengthened through PjBL and communicative competence understanding. Both micro and macro components of communication competence are essential for English learners and speakers. Syntax, morphology, semantics, and phonology are all areas where micro components perform. The three macro components also strongly contribute to the achievement of communicative competencies, including discourse competence, sociolinguistics, and communication techniques. These two components are essential for creating a more dynamic and enactive educational interaction space and are mutually reinforcing.

Published: October 2023

Este artigo busca evidenciar a trajetória do atendimento das crianças pequenas no Brasil no período que se estende desde as iniciativas implantadas pelo movimento higienista, principalmente pelo IPAI do Rio de Janeiro (1927) até o momento em que a educação infantil é compreendida como direito à educação e como primeira etapa da educação básica por meio da CF de 1988, e da LDB de 1996, a fim de verificar avanços e retrocessos na garantia do atendimento no processo educativo. Utilizamos para isso análises bibliográficas e de legislações que nos possibilitam inferir sobre a temática, procurando os indícios ou pistas de um processo educativo para as crianças que estavam em creches (asilos), escolas maternais, jardins de infância e/ou pré-escolas vinculados a Assistência Social e passam a ser atendidas pelas Secretarias de Educação. É preciso considerar que pretendemos problematizar a trajetória histórica do atendimento à criança na faixa etária de zero a seis anos a fim de que possamos contextualizar o passado para aprimorar nosso olhar para o presente da educação infantil.
