Spoken Word Frequency in the Hindi Language
Authors: Verma Himanshu , Patil Gouri Shanker
Published: March 2023

Objective

Limited studies related to spoken word corpus in the Indian context are available in the literature. To fulfill the demands of the spoken word frequency database in Hindi for advance psycholinguistic and cognitive studies, we tried to establish the preliminary spoken word database of Hindi language for children studying in Grade VI to Grade IX.

Methods

To create the spoken word corpus a recorder was given to subjects to record their conversation. The recorded sample was transcribed into Hindi text using voice note II software. The transcribed sample was uploaded into Text Analyzer software, and word frequency, the number of syllables, and lexical density were computed.

Results

Spoken word corpus consists of a total of 49,476 words. Lexical density was higher for females than males because the female database contains more unique words. The study also revealed that subjects used functional words and verbs more frequently, followed by nouns.

Conclusion

We can conclude that the current database provides information about the high-frequency and low-frequency words used by children studying in Grade VI to Grade IX. This database will be helpful in psycholinguistic and cognitive experiments; however, the present corpus included data from the middle socioeconomic group and contained fewer words. The present study is the preliminary study future study demands and requires an extensive word database.

Introduction

India lacks workforce in the field of speech and hearing leading to the hire of speech and hearing technicians at many work setups. They are allowed to work independently which affects the efficacy of rehabilitation to a greater extent. This alarm necessitates the investigation of reasons for brain drain which will, in turn, help in improvising the speech and hearing services in India.

Methods

An e-survey was conducted by circulating a questionnaire which included 10 questions seeking information on the type of job placement, number of shifts in job, the reasons for shifting jobs, satisfaction level at workplace, and percentage of professionals preferring India and/or abroad for job placement. The questionnaire was sent to 3700 professionals, out of whom 360 professionals responded.

Results

Lower income, poor professional growth, and unsatisfied job profile were found to be the major reasons for brain drain in India.

Conclusion

A regular detailed investigation of reasons for frequent brain drain is required by the concerned bodies in India. In addition, steps should also be taken to rectify the same. Such careful actions may increase the potential employment opportunities for efficient fully trained speech and hearing professionals in India. This will, in turn, raise good quality speech and hearing services in India.
Articulation Rate and Speech Rhythm in Child-Directed Speech and Adult-Directed Speech
Authors: Shivaswamy Jyothi , Maruthy Santosh , Barman Animesh
Published: March 2023

Introduction

Studies have demonstrated that mothers exaggerate linguistic, segmental and supra-segmental properties of Child-Directed Speech. However, these studies have majorly focused on acoustic characteristics of pitch and its related measures. There has been relatively little research on speech rhythm. Though many studies report slower articulation rate relative to Adult-Directed Speech, still there is no conclusive evidence across different languages.

Aims

This study aims to examine articulation rate and rhythm in Kannada speaking mothers, a Dravidian language which is less explored.

Methods and Material

Twenty-five dyads of mothers and their children were recruited from the local community through random sampling for the study. The mean age of these children was 2.08 years (SD = 0.61, range= 1.89). The mean age of mothers was 30.96 years (SD= 3.44, range= 13). Articulation rate was calculated by dividing the number of syllables per second by the total duration of fluent speech in each two-minute sample. Speech rhythm was measured using an automatized approach, i.e., Envelope Modulation Spectra (EMS).

Results

Results demonstrated that mothers spoke slower to their children when compared to speaking with the adult supporting the universality nature of Child-Directed Speech.

Conclusions

However, results showed no conclusive evidence for the analysis of speech rhythm and hence gives a future direction to explore on the use of EMS in the normal population is mandated.
Parental Perspectives on Shared Reading Practices at Home
Authors: Vrinda R. , Baiju Aparna , Rajendran Devika
Published: March 2023

Background

Shared book reading is the interaction that occurs between child and adult when they look at or read a book together and it facilitates the development of emergent literacy and language skills. In India, oral narration of stories was the tradition and shared book reading is not a culturally familiar routine. Shared reading practice among preschoolers in India is a less explored research area.

Aim

The present study explores the parental perspectives and practices on shared reading at home and also its association with Socioeconomic status.

Method

Forty -one parents of 3-5 years old typically developing children with Malayalam as native language participated in the study. The questionnaire on 'Parental Perspectives on Storybook Reading in Indian Home Contexts' was used to understand the parental perspectives on shared reading, and the “Modified Kuppuswamy Socioeconomic Scale” was used to understand the socioeconomic status of the family.

Results

73.1% of parents reported that they began reading to their children between 2 and 4 years of age, 43.9% read 3–5 times per week, and 58.5% had fewer than 10 books in the home. The parental attitude and beliefs about shared reading did not correlate with SES and child's age.

Conclusion

Overall, the findings indicate that parents were aware of the benefits of storybook reading and were generally positive about it. The findings of this study provide preliminary information on the home literacy environment (HLE) in Kerala. Understanding more about the parental storybook reading practice will facilitate the development of parent programs to enhance and promote quality HLEs.
Vocal Changes in Different Phases of Menstrual Cycle
Authors: Narasimhan S. V. , Pooja M.
Published: March 2023

Introduction

Spectral and cepstral analyses of voice have potential clinical implications and can be used as a quantitative acoustic index to assess vocal function in various phases of the menstrual cycle. However, only a handful of studies have attempted to investigate these measures to document the vocal changes across various phases of the menstrual cycle and the results are not conclusive. Therefore, the study aimed to document the acoustic, spectral, and cepstral parameters of voice across the four phases of the menstrual cycle.

Methods

Phonation samples were recorded during four phases of the menstrual cycle –menstrual phase, follicular phase, ovulation phase, and luteal phase – from 30 female participants. None of the participants reported any hormone-related problems, presence, or history of any voice problems and had a regular menstrual cycle at least from the past 5 years. All the phonation samples were analyzed, and the acoustic, spectral, and cepstral parameters were extracted.

Results

Fundamental frequency, H1-H2, and cepstral peak prominence (CPP) values were significantly different across the phases of the menstrual cycle. Across the phases of the menstrual cycle, the fundamental frequency, H1-H2, and the CPP values were optimal during the follicular phase and the deviant values were noted during the luteal phase of the menstrual cycle.

Conclusion

Future investigations could include the analysis of cepstral and spectral parameters extracted from both the phonation and speech samples that can provide more penetrating and ample in-depth insights into the voice changes across the various phases of the menstrual cycle.
Cervical cancer care cascade among women living with human immunodeficiency virus in 13 sub-Saharan Africa countries between 2019 and 2021
Authors: Ng'ambi Wingston Felix , Zyambo Cosmas
Published: March 2023

Introduction:

Cervical cancer (CC) is the fourth main cause of death among women. Poor uptake of CC screening has indirect effects on increased mortality among women. Therefore, we employed the care cascade to understand the CC outcomes in sub-Saharan Africa (SSA) using the PEPFAR Panorama CC data collected between 2019 and 2021.

Methods:

A retrospective study using the PEPFAR Panorama CC data, from 13 countries from SSA, was performed. We calculated the proportions of women who were screened, those who were found to have positive results after screening for CC, and those who were linked to CC treatment.

Results:

A total of 2,312,541 were eligible for screening and of these, 1,429,925 (62%) were screened for CC. Of these, 162,758 (11%) were diagnosed with CC. Of these, 115,890 (71%) were provided with treatment. CC screening increased from 41% in 2019 to 90% in 2021. The CC diagnosis ranged from 8% in 2019 to 13% in 2021. CC treatment coverage increased from 64% in 2019 to 75% in 2021. Screening uptake, CC diagnosis, and CC treatment coverage varied by country and age of the women.

Conclusion:

There were variations in CC screening and treatment uptake for CC by country and age. With these inequalities in screening and coverage of treatment for CC, eliminating CC as stipulated in the sustainable development goals will remain a farfetched dream.
Overweight and obesity, the clock ticking in India? A secondary analysis of trends of prevalence, patterns, and predictors from 2005 to 2020 using the National Family Health Survey
Authors: Singh Geetu , Agrawal Renu , Tripathi Neelika , Verma Arti
Published: March 2023

Introduction:

The aim of the World Health Organization (WHO) is to reduce global obesity to 2010 levels by 2025 is threatened by the increasing number of overweight and obese Indians and country's population size.

Objectives:

This study was planned with the objectives to determine the trends of prevalence and predictors of overweight and obesity in India over one and a half decade (2005–2021) using the National Family Health Survey (NFHS) (3, 4, and 5) and probably first analysis to describe waist-to-hip ratio (WHR) as an indicator of obesity in large population.

Methods:

The outcome measures, for assessing overweight and obesity were the body mass index (BMI) by using WHO classifications (overweight/obese defined by BMI ≥25 kg/m2 and waist-to-hip ratio (WHR).

Results:

Our analysis showed that in the 15-year period, the repeated Indian NFHS recorded the combined prevalence of overweight or obese (BMI ≥25 kg/m2) among women (15 and 49 years) and men (15 and 49 years) increased from 12.6% to 24% and 9.3% to 22.9% respectively. All the northern, western, southern, eastern, and north-eastern states have shown a rise in the prevalence of overweight and obesity in males and females in NFHS-5 since NFHS-3. The rise in rural areas is appreciable much, in women from 8.6% (NFHS-3) to 19.7% (NFHS-5) and in men from 7.3% (NFHS-3) to 19.3% (NFHS-5). The highest WHR was observed among the women (both urban and rural) of Jammu and Kashmir followed by Ladakh.

Conclusion:

The results underline the increasing prevalence of overweight/obesity and central obesity in both men and women across both urban and rural regions of India. Policymakers should timely have solutions for this growing problem to reduce burden on health-care system.

Authors: Kumar Rashmi P , Fathima Farah Naaz , Agrawal Twinkle , Misquith Dominic , Gururaj Gopalkrishna
Published: March 2023

Background:

Road traffic injuries (RTIs) are the major causes of mortality, morbidity, and disability among young adults and pose a significant economic burden to individuals, families, and communities.

Objective:

To estimate the cost of care at discharge, 3 months and 6 months among patients with RTIs admitted to a private tertiary hospital in Bengaluru, India.

Methods:

A cost-of-illness study from patient's perspective was done among 150 hospitalized injured subjects with RTIs admitted to a tertiary care hospital in Bengaluru city. A face validated, structured interview schedule was administered in local language at baseline (hospital discharge time), 1 month and at 6 months to capture data on direct medical costs, direct nonmedical costs, and indirect costs incurred by the RTI victims and their family members. Hospital bills were reviewed for all the patients included in the study.

Results:

Among the 150 study participants, majority were men (94.67%), with a mean age of 35.36 years ± 14.62 years and majority were two-wheeler riders/pillions and pedestrians. Our results show the median cost incurred for care of RTI to be INR 106,374 (inter quartile range [IQR] 57,402–163,250) (USD 1418 [IQR 765–2176]). Direct medical costs contributed to 66% of the costs, whereas direct nonmedical and indirect costs contributed to 21% and 13% of the total costs, respectively.

Conclusion:

RTIs contribute to significant economic burden to patients. While prevention should be our primary goal, health financing and risk protection mechanisms should be strengthened by streamlining insurance coverage mechanisms to reduce out-of-pocket expenditure.

Authors: Boppana Sri Harsha , Ravula Nikhil Reddy , Simhachalam Kutikuppala L. V. , Sivaraj Nagarjuna , Raja Hamsa C. H. , Mahajan Sidharth , Chaitanya P. Siva
Published: March 2023

Background:

A major modifiable risk factor for cardiovascular disease is hypertension. Resistant hypertension is observed to be associated with an increased likelihood of deleterious effects such as cardiovascular events, cerebrovascular accident, and renal dysfunction. The raised levels of inflammatory cytokines in the plasma like the C-reactive protein (CRP) have previously been observed to be significantly raised in hypertensive patients, but the overlying mechanisms corresponding to these processes remain unknown.

Materials and Methods:

In essence, this was an observational study with data collected from a population at a specific moment in the time to assess the relationships between the variables analyzed. A total of 200 individuals with arterial hypertension took part in the study. Fasting venous blood was obtained to evaluate plasma lipoprotein-related phospholipase A2 (Lp-PLA2) activity, and baseline data were collected. To diagnose RH, a 24-h ambulatory blood pressure management was done.

Results:

RH was observed among 100 patients and found to be predominant among males and older individuals, who were smokers and having hypertension for a longer period of time with higher Lp-PLA2 activity. More RH patients used calcium channel blockers and diuretics, while a fewer used angiotensin-converting enzyme inhibitors, angiotensin receptor blockers, and statins (P 0.05 for all comparisons).

Conclusion:

The plasma Lp-PLA2 activity beyond a certain threshold suggests a raised risk of RH, and the statins can help in reducing the RH incidence among persons with high Lp-PLA2 levels.

A prospective study was conducted to assess the effectiveness of learning from an online public health course (6th International Course on Public Health Approaches to Noncommunicable Diseases) among participants from India. The knowledge significantly improved after attending the online public health practice course (P < 0.05) and remained without any significant change over the period of time till 6 months after the online course (P = 0.988). Majority of the respondents were applying the learnings from the course in their program management (64.7%–89.3%). Online delivery of public health courses in India has shown to improve knowledge and maintain the acquired knowledge.
Insight into the species identification and distribution of Grateloupiaceae (Halymeniales, Rhodophyta) having Grateloupia filicina-like morphology in the Northwest Pacific
Authors: Kim Su Yeon , Boo Sung Min , Yoon Hawn Su , Kim Myung Sook
Published: March 2023

Accurately identifying species is the basis of all biological studies. There has been much confusion in the identification of Grateloupiacean species, which have finely pinnate gross morphology similar to Grateloupia filicina (the type species of the family). The objective of this study was to comprehensively investigate species identification and distribution of G. filicina-like species in the Northwest Pacific, based on the rbcL sequences. A total of 118 specimens from 78 sites in Korea and Japan were collected from 2001 to 2021 and analyzed for their rbcL sequences. Additional 341 sequences downloaded from the GenBank were included in our comprehensive dataset. Based on these sequences, we documented the nomenclatural history and geographical distribution of the species, and commented on the application of species name. G. asiatica was the most abundant G. filicina-like species in the Northwest Pacific, and its high degree of morphological variation caused many misidentifications. In particular, G. dalianensis, G. serra and G. variata require reconsideration of their conspecificity with G. asiatica using more specimens from China. By contrast, G. oligoclora was presumed to be a heterotypic synonym of G. subpectinata. The occurrence of G. acuminata, G. ramosissima, and G. livida in Korea resulted from misidentifications with other species.
Global Evidence of Oil Supply Shocks and Climate Risk a GARCH-MIDAS Approach
Authors: AYINDE Taofeek O. , ADEYEMI Farouq A.
Published: March 2023

The study examines the global evidence of oil supply shocks and climate risks. Using the GARCH-MIDAS regression and a dataset spanning the period 2000 – 2018, we find that oil supply shocks are a better predictor of climate risks than the inherent environmental factors. The evidence indicates that oil supply shocks dampen climate risk challenges through the reservation and conservation channels. To reduce oil supply shocks, the study recommends the deployment of moral suasions in oil resource-rich countries.

Authors: Xian Wen Sim  , Sie Long Kek  , Sy Yi Sim  , Jiao Li
Published: March 2023

This study aims to optimally control the level of a four-tank system at the steady state in the random disturbance environment using the stochastic approximation (SA) approach. Firstly, the stochastic optimal control problem of an equivalent discrete-time is introduced, where the voltages to the pumps are the control inputs. By minimizing the sum of squared errors, the liquid levels are estimated. Then, first-order necessary conditions are derived by defining the Hamiltonian function. Thus, the optimal voltages are calculated based on the estimated liquid levels to update the gradient of the cost function. Finally, for illustration, parameters in the system are considered and a simulation is conducted. The simulation results show that the state estimation and control law design can perform well, and the liquid levels are addressed along the steady state. In conclusion, the applicability of the SA approach for handling a four-tank system with random disturbances is demonstrated.

Published: March 2023

Floods and rain significantly impact the economy of many agricultural countries in the world. Early prediction of rain and floods can dramatically help prevent natural disaster damage. This paper presents a machine learning and data-driven method that can accurately predict short-term rainfall. Various machine learning classification algorithms have been implemented on an Australian weather dataset to train and develop an accurate and reliable model. To choose the best suitable prediction model, diverse machine learning algorithms have been applied for classification as well. Eventually, the performance of the models has been compared based on standard performance measurement metrics. The finding shows that the hist gradient boosting classifier has given the highest accuracy of 91%, with a good F1 value and receiver operating characteristic, the area under the curve score.
Building Information Modeling in the Architecture and Construction Industry
Authors: Jerome Jordan Faz Famadico
Published: March 2023

This study aims to investigate the benefits, risks, barriers, and approaches of building information modeling (BIM) implementation in the architecture, engineering and construction (AEC) industries. Descriptive research methods such as surveys and key informant interviews are used to gather data. Respondents in the survey come from different AEC companies and are selected with a purposive sampling method. Descriptive statistics and one-way analysis of variance (ANOVA) are utilized to analyze the data. The narrative analysis method is also performed to validate the research findings through a desk review of secondary data. The result shows that the major benefit of BIM is earlier and more accurate design visualization, while the main risk is accountability and control of data entry into the model. Moreover, the major barrier to BIM implementation is the high acquisition cost, and the most recommended approach is to increase the availability of BIM technology.

Authors: Pavlović Ratko , Vrcić Mensur , Radulović Nikola
Published: March 2023

Endurance-type disciplines (running, cycling, biathlon) define the cyclic structure of an athlete's movements, which, in addition to functional parameters, also includes an adequate fitness profile. Based on the detection, analysis and evaluation of these parameters, it is possible to define the fitness profile of the competitors as well as possible mutual differences. The current case study analyzes the fitness profile of competitors of three different disciplines (middle and long distances, cycling, ski biathlon) of top-level competitors, members of national teams. The study was conducted: Uroš Gutić (UG) - runner middle and long distances, member of AK "Sarajevo" and the BIH athletic national team; Milan Milivojević (MM) – cyclist, member of Cycling club "Borac" Čačak (Serbia), and the member Serbian national team; Stefan Lopatić (SL) – ski biathlete, member SK "Romanija" Pale, and BIH national team. A total of 12 parameters were measured to assess the fitness profile (repetitive strength, explosive strength, speed and agility). The results recorded considerable homogeneity of the sample with mutual differences. In addition to mutual differences, all study participants are characterized by an extremely good fitness profile, as shown by the measurement results.

Authors: Romero Javier Osnaya , Sánchez Jesús Gracia , Mariles Óscar Arturo Fuentes , Martínez Víctor Manuel Ortiz
Published: March 2023

En canales revestidos de fuerte pendiente se presentar velocidades de flujo tan altas, que es necesario modificar su rugosidad para disminuirlas. En este trabajo se presenta un procedimiento para determinar el grado de confianza de que puede esperarse de uno de los criterios disponibles para el diseño de rugosidades artificiales de fondo altas en canales revestidos.  Con base en el teorema de Buckingham se proponen expresiones para llevar a cabo el diseño mencionado.  Se desarrollan diferentes ejemplos de cálculo que incluyen un tramo de transición de rugosidad alta a la entrada del canal.  El estudio concluye que la rugosidad de fondo propuesta ocasiona flujos más estables y aunque implica un costo adicional, es recomendable considerar a la rugosidad artificial cuando se desea reducir mucho la velocidad del flujo de agua al final de esta clase de conductos, pero mantener el flujo de gastos bajos para evitar su almacenamiento en el canal.

The Relationship between VIX and Technical Indicator: The Analysis of Shared-Frailty Model
Authors: Chen Jo-Hui , Sabbor Hussain , Chen Fu-Ying
Published: March 2023

Abstract

This article uses a shared-fragility model for the recurrent spell length for the volatility index (VIX). Ten future VIXs have been chosen. The article examines the impacts of the top five market technical indicators, including the Moving Average Convergence–Divergence (MACD), Relative Strength Index (RSI), Triple Exponential Average (TRIX), Historical Volatility (HV), and Vertical Horizontal Filter (VHF). On the spell time of upward, downward, and overall trends, our findings supported the hypothesis that investors can better understand the pattern and trend of volatility risk by impacting the relevant technical index on various futures VIXs. We examined how technical indicators affect the volatility index. In the Weibull distribution, the upward trend data has the most significant values. The positive values provided by MACD and TRIX imply a strong positive relationship with VIX and a longer survival time. The results also show that the greater the value of historical volatility, the greater the risk to commercial investments. As a result, the possibility of VIX in the trading pattern has a shorter time because the selling signals are coming out.

JEL classification numbers: G15.
Keywords: VIX Index, Technical Indicator, Shared-frailty Model.
A problemática ambiental na perspectiva interdisciplinar nos livros didáticos de ciências e geografia do ensino fundamental
Authors:   , Amorim Ana Maria Haddad Bernardino de
Published: March 2023

A questão ambiental requer uma análise conjunta envolvendo a perspectiva ambiental, econômica, política, educacional e social. Tais perspectivas não são iguais, porém são complementares com influência mútua. E, nesse sentido, qualquer tentativa de teorizar a questão ambiental, requer uma análise das demais áreas de forma relacional e dialógica. Este trabalho de cunho educacional evidencia a questão ambiental sob um viés interdisciplinar a partir de uma ferramenta pedagógica que é o livro didático. Ao analisar esse material didático, objetivou-se perceber a presença (ou ausência) da questão ambiental de forma interdisciplinar nos livros de ciência e geografia, considerando essas áreas mais próximas da temática e como elas promoviam essa integração metodológica e pedagógica. O meio ambiente, por envolver essas diversas perspectivas e categorias de análise, leva consigo uma complexidade. Portanto, uma análise, ainda que de modo cognitivo e pedagógica, exige do pesquisador (e também por parte do leitor) apropriar-se da temática sob o prisma da conjuntura socioambiental, nunca de forma isolada, mas relacional, problematizando a o meio ambiente compreendendo suas potencialidades, dinâmicas próprias e intervenções humanas. Palavras-chave: Questão ambiental. Interdisciplinaridade. Livro didático.
Participação do silício nos processos de absorção, translocação e atenuação da toxicidade do arsênio em alface (Lactuca sativa L.)
Authors:   , Gomes Filho Antonio Aristides Pereira
Published: March 2023

O arsênio (As) causa a superprodução de espécies reativas de oxigênio (EROs) que acarreta danos em todo o metabolismo vegetal. Plantas contaminadas representam sério risco à saúde, visto que o consumo de alimentos contaminados é uma das formas de intoxicação em seres humanos. O silício é um elemento benéfico para plantas e reconhecido por aliviar o estresse abiótico, incluindo o estresse por As. Portanto, buscamos avaliar o efeito do silício, iônico e nanoparticulado, na mitigação do estresse por As em alface. Para isso, plantas de alface foram cultivadas hidroponicamente por 40 dias e, após aclimatação por 5 dias, foram submetidas a 50 μM de arsenito (As III ) e arsenato (As V ) e 2 mM de silício iônico (Si) e silício nanoparticulado (SiNP) durante dois períodos de exposição (24 e 72 h). Foram realizadas análises relacionadas a anatomia, fotossíntese e bioquímica dessas plantas. Os resultados mostraram que o As, tanto As III quanto As V , causa efeitos negativos sobre todos os parâmetros avaliados e ambas as formas de silício foram capazes de diminuir o estresse por As, por meio da diminuição da absorção e da concentração nas folhas, melhoria nos aspectos anatômicos e modulação da maquinaria antioxidante, onde se destaca uma reduzida peroxidação lipídica. Além disso, contatamos que nanopartículas de silício são tão eficientes quanto a forma iônica na diminuição do estresse por As. Palavras-chave: Estresse oxidativo. Sistema antioxidante. Nanopartículas de silício.
Narratively Inquiring Into Experience, Narratively Attending to Environmental Education Teachers’ Identity
Authors: Grillia Naya , Daskolia Maria
Published: March 2023

In the grand narrative of Environmental Education and Education for Sustainable Development, teachers are recognized as key agents of quality education and as catalysts for the learning that takes place. Yet, this widespread assumption has failed to attract sufficient attention to examine ‘who environmental education teachers are’ by prioritizing research around their identity. Our study here goes along this line of thought to narratively inquire into the experience of four Greek teachers actively engaged with environmental education. Based on the narrative conception of identity as ‘stories to live by’ as a basic tenet, it is argued that teachers’ identity is composed of the stories they live throughout their personal and professional lives. In this paper we unfold the story of one of these teachers, Zoe, and highlight how her ‘stories to live by’ changed throughout her life, shaping and re-shaping her identity. By proposing a narrative and relational way of thinking about teacher identity, we focus on the identity shifts Zoe unveils and connects them to the stories she experienced in past and present encounters she had with her family, teachers, friends, and colleagues.
How to Handle a Case of Redundant Publications in Four Elsevier Journals?
Authors: Teixeira da Silva Jaime A.
Published: March 2023

Current ethical guidelines, as defined by the Committee on Publication Ethics (COPE), note that redundant publications or duplicate copies should be retracted because they partake no new information, and may be perceived as unfair. Elsevier and its journals are COPE members. In 2000, four Elsevier journals (Anaerobe, Journal of Theoretical Biology, Journal of Autoimmunity, Food Microbiology) published an identically worded notice related to the digital object identifier (DOI), i.e., it was published in quadruplicate (four copies). Despite an alert to all four journals about this quadruplicate, none were retracted. If academics would like to cite this announcement, which of the four copies should they use? This case study raises an important deontological argument regarding the laissez-faire attitude of these journals, which charge a fee (US$27.95-31.50) to access this document’s four PDFs. Yet, other cases of duplications/redundant publication in Elsevier journals are frequently retracted. In the case of these four DOI-related papers, what does ignoring the three redundant copies suggest?

Authors: Simpson James
Published: March 2023

Purpose: The purpose of this study was to find out the impact of chosen psychological factors to backslide among recovering alcoholics of Australian rehabilitation centers.

Methodology: The study adopted a desktop methodology. Desk research refers to secondary data or that which can be collected without fieldwork. Desk research is basically involved in collecting data from existing resources hence it is often considered a low-cost technique as compared to field research, as the main cost is involved in executive’s time, telephone charges and directories. Thus, the study relied on already published studies, reports and statistics. This secondary data was easily accessed through the online journals and library.

Results: The results revealed that there exist conceptual and contextual gaps relating to the study on psychological factors to backslide among recovering alcoholics of Australian rehabilitation centers. Preliminary empirical review reveals that the chosen psychological factor that mostly contributed to backslide was dwelling on resentment that causes anger due to unresolved conflict.

Unique Contribution to Theory, Practice and Policy: Psychoanalytic theory and social learning theory may be used to categorize the key work design factors which may relate to stress-related health issues.  The results of this research will form the basis for further research to aid psychologists and counsellors to understand their critical role in the alcohol treatment and rehabilitation and make them more effective in the execution of their duties.

Purpose: The purpose of this study was to analyze the determinants of psycho-educational assessment for learners with learning disabilities (LD) in New Zealand.

Methodology: The study adopted a desktop methodology. Desk research refers to secondary data or that which can be collected without fieldwork. Desk research is basically involved in collecting data from existing resources hence it is often considered a low-cost technique as compared to field research, as the main cost is involved in executive’s time, telephone charges and directories. Thus, the study relied on already published studies, reports and statistics. This secondary data was easily accessed through the online journals and library.

Results: The results revealed that there exist conceptual and contextual gaps relating to the study on psycho-education for learners with learning disabilities in New Zealand. Preliminary empirical review reveals that main challenges in psycho-educational assessment were linked to lack of proper stakeholder collaboration and interests, inadequate funding and resources, time taken in assessment and community backgrounds of the learners.

Unique Contribution to Theory, Practice and Policy: The transformative paradigm may be used to provide a framework for research in the disability communities that is more attuned to handling diversity within, aims to build on strengths within communities, develops solidarity with other groups which are marginalized, and changes its identity politics to a socio-cultural perspective.

Pangasius catfish, Pangasius nasutus, is a promising candidate for aquaculture due to its high market value. However, the presence of pathogenic bacteria in Aeromonas hydrophila is a major concern in P. nasutus farming in this country. This study determines the pathogenicity of A. hydrophila in P. nasutus. A total of 80 P. nasutus juveniles were intraperitoneally injected with 0, 103, 105, and 107 CFU mL-1 of A. hydrophila and monitored until 240 hr. The infected moribund fish’s kidneys, livers, and spleens were collected for histopathological analysis. The LD50-240hr value was found at 0.8 × 104 CFU/ml of A. hydrophila. The percentage of mortality in 0, 103, 105, and 107 CFU/ml infected groups were found to be at 0, 40, 60, and 90%, respectively. The infected fish showed congestion at the base of the fin, ascites, enlarged gall bladder, and swollen spleen. It is the earliest report on A. hydrophila’s pathogenicity in high-value native fish, P. nasutus.

Can diffusion-weighted imaging be used in the examination
of peritoneal fluids?
Authors: Keskin Zeynep
Published: March 2023

Introduction

The aetiology of free fluid detected in the abdomen can be investigated with magnetic resonance imaging (MRI). The aim of this study is to investigate the effectiveness of diffusion-weighted images (DWI) and apparent diffusion coefficient (ADC) values in the evaluation of abdominopelvic fluids.

Material and methods

Patients with abdominopelvic fluid detected on MRI of the lower abdomen were included in this retrospective, single-centre study. Paracentesis and fluid analysis was performed in these patients. The average ADC values in fluids were measured by a radiologist. A cut-off value was determined, and the specificity, sensitivity, negative predictive value (NPV), and positive predictive values (PPV) were calculated. Intra-observer agreement was investigated.

Results

The study comprised 41 (33 female) patients, and their mean age was 48 ± 4.02 years. The ADC values in infective fluids were significantly higher than in non-infective fluids (p < 0.001). The cut-off value used was 2.95 × 10-3 mm²/s. According to this threshold value, sensitivity in distinguishing non-infective from infective fluids was 88%, specificity was 93.8%, PPV was 95.7%, and NPV was 83.3%. Intra-observer agreement was strong in ADC values (κ = 0.699) (p < 0.001).

Conclusions

We concluded that the ADC value is a non-invasive, reliable, reproducible imaging parameter that can be useful in the evaluation and characterization of abdominal fluids.

Authors: Wang Qingbo
Published: March 2023

This paper considers the problem of real-time estimating the moving target acceleration in frequency modulated continuous wave (FMCW) radar. Based on the accelerated target FMCW radar echo signal model, after utilizing KeyStone transform to eliminate the ef ect of range migration on the signal parameters estimation. An improved fractional Fourier transform (FrFT) and optimized the best matching rotation angle search strategy is proposed to estimate the chirp rate of doppler dimension echosignal related to the target acceleration. Compared with the traditional FrFT, the approach in this paper has less computation and significantly reduced processing time while ensuring estimation accuracy. The proposed method is demonstrated with simulation and measurement data.

Published: March 2023

In this study, nitrogen-doped graphene quantum dots (N-GQDs) were successfully synthesized by hydrothermal method. The morphology and adsorption properties of samples were studied through high resolution transmission electron microscopy (HR-TEM) and UV-Vis absorption spectra. The UV-Vis absorption spectra showed that the typical absorption peaks at 234 nm and 342 nm and 640 nm were characteristic of the N-GQDs materials. HR-TEM image showed that the average size of N-GQDs is about 5 nm. Compared with the absorption peak at 342 nm (strongest absorption peak) of N-GQDs, the absorption peak of N-GQDs·Fe3+ shift towards lower wavelengths at 295 nm, which is due to the complexation between hydroxyl, carboxyl, pyridinic nitrogengroups of the N-GQDs and Fe3+ ions. These results indicated that the N-GQDs materials could have potential application for detecte Fe3+ in the water.
