Authors: Lu Stephen , Danchenko Monika , Macaluso Kevin R. , Ribeiro José M. C.
Published: January 2023

The hematophagous behaviour emerged independently in several instances during arthropod evolution. Survey of salivary gland and saliva composition and its pharmacological activity led to the conclusion that blood-feeding arthropods evolved a distinct salivary mixture that can interfere with host defensive response, thus facilitating blood acquisition and pathogen transmission. The cat flea, Ctenocephalides felis, is the major vector of several pathogens, including Rickettsia typhi, Rickettsia felis and Bartonella spp. and therefore, represents an important insect species from the medical and veterinary perspectives. Previously, a Sanger-based sialome of adult C. felis female salivary glands was published and reported 1,840 expressing sequence tags (ESTs) which were assembled into 896 contigs. Here, we provide a deeper insight into C. felis salivary gland composition using an Illumina-based sequencing approach. In the current dataset, we report 8,892 coding sequences (CDS) classified into 27 functional classes, which were assembled from 42,754,615 reads. Moreover, we paired our RNAseq data with a mass spectrometry analysis using the translated transcripts as a reference, confirming the presence of several putative secreted protein families in the cat flea salivary gland homogenates. Both transcriptomic and proteomic approaches confirmed that FS-H-like proteins and acid phosphatases lacking their putative catalytic residues are the two most abundant salivary proteins families of C. felis and are potentially related to blood acquisition. We also report several novel sequences similar to apyrases, odorant binding proteins, antigen 5, cholinesterases, proteases, and proteases inhibitors, in addition to putative novel sequences that presented low or no sequence identity to previously deposited sequences. Together, the data represents an extended reference for the identification and characterization of the pharmacological activity present in C. felis salivary glands.
DDQR (dynamic DNA QR coding): An efficient algorithm to represent DNA barcode sequences
Authors: Wang Yujun , Yao Xinjing , Liu Rui , Liu Chang
Published: January 2023

A DNA barcode is a short piece of standard DNA sequence used for species determination and discrimination. Representation of DNA barcodes is essential for DNA barcodes’ applications in the transportation and recognition of biological materials. Previously, we have compared different strategies for representing the DNA barcodes. In the present study, we have developed a compression algorithm based on binary coding or Huffman coding scheme, followed by converting the binary digits into Base64 digits. The combination of this compression algorithm and the QR representation leads to the dynamic DNA QR coding algorithm (DDQR). We tested the DDQR algorithm on simulated data and real DNA barcode sequences from the commonly used plant and animal DNA barcode markers: rbcL, matK, trnH-psbA, ITS2, and COI. We compared the compression efficiency of DDQR and another state-of-the-art DNA compression algorithm GeCo3 for sequences with various base compositions and lengths. We found that DDQR had a higher compression rate than GeCo3 for DNA sequences shorter than 800 bp, which is the typical size range for DNA barcodes. We also upgraded a web server (http://www.1kmpg.cn/ddqr) that provides three functions: retrieval of DNA barcode sequences, encoding DNA barcode sequences to DDQR codes, and decoding DDQR codes to DNA barcode sequences. The DDQR algorithm and the webserver will be invaluable to applying DNA barcode technology in the food and traditional medicine industries.

Published: January 2023

Pain is a prevalent and debilitating healthcare problem. Since pharmacological treatments have numerous side-effects, additional treatment could be beneficial. Music has been shown to affect the pain perception and the pain threshold. The objective of this observational study was to evaluate the effect of preferred music as opposed to disliked music on pain (tolerance) thresholds and perceived pain intensity in healthy volunteers. Pain thresholds were measured via quantitative sensory testing. The volunteers were randomly assigned to either handheld pressure algometry to assess the pressure pain threshold to or electrical measurements to assess the electrical pain tolerance threshold while listening to preferred and disliked music. The pain thresholds were administered on the dorsal side of the forearm. The perceived pain intensity was assessed via a numerical rating scale, ranging from 0 (no pain) to 10 (worst pain imaginable). In total 415 volunteers were included in this study. The pressure pain threshold was assessed in 277 volunteers and in the electrical pain tolerance threshold test 138 volunteers were entered. In both groups, preferred music yielded higher pain thresholds than disliked music (P<0.001) and lower perceived pain intensity during the stimulus (P = 0.003). Moreover, the highest pain thresholds of both pressure pain and electrical pain tolerance thresholds were obtained when the preferred music was preceded by disliked music. Listening to preferred music when receiving noxious stimuli leads to higher pain thresholds and lower perceived pain scores in comparison with disliked music. Preferred music could be beneficial for patients with pain or undergoing painful procedures.

Published: January 2023

Background

Disclosure of Human Immunodeficiency Virus (HIV) status to sexual partners plays a significant role in the successful prevention and care of HIV infection. Pregnant women who did not reveal their HIV status to their sexual partners make the prevention and control efforts challenging. Therefore, this study was aimed to assess HIV status disclosure to sexual partners and associated factors among pregnant women living with HIV attending prenatal care in Amhara Regional state referral Hospitals, Ethiopia in 2021.

Methods

An institution-based cross-sectional study was conducted from October 17th, 2020 to March 1st, 2021. A total of 423 pregnant women living with HIV were participated in this study. A systematic random sampling technique was used to select all eligible women. Data was collected using a semi-structured, pretested, and interviewer-administered questionnaire. EPI INFO version 7 and SPSS version 21 were used for data entry and analysis, respectively. Both univariable and multivariable logistic regression analyses were performed to find factors associated with women’s disclosure status to a sexual partner. Statistical association was decided based on the adjusted odds ratio (AOR) with its 95% Confidence Interval (CI) and p-value of ≤ 0.05.

Results

The prevalence of disclosure of their HIV status to their sexual partners was 73% (95% CI: 68.9%, 77.3%). Being an urban resident (AOR = 5.04, 95% CI: 2.14, 11.81), diagnosed HIV before pregnancy (AOR = 7.77, 95% CI: 3.09, 19.52), disclosing their HIV status to others (AOR = 7.01, 95% CI: 3.78, 13.25), planned pregnancy (AOR = 2.46, 95% CI: 1.32, 4.57), and having good knowledge on HIV/AIDS prevention (AOR = 2.19, 95% CI:1.22, 3.94) were found to be statistically significant with women’s disclosure of their HIV status to their sexual partner.

Conclusion

In this study, nearly three-fourth of pregnant women disclosed their HIV status to their sexual partner. Thus, setting strategies in preventing unplanned pregnancy, HIV diagnosed before pregnancy, and increasing knowledge of HIV prevention will have significant role in escalating women’s disclosure status.

Published: January 2023

Low-effort, reliable diagnostics of digital dermatitis (DD) are needed, especially for lesions warranting treatment, regardless of milking system or hygienic condition of the feet. The primary aim of this study was to test the association of infrared thermography (IRT) from unwashed hind feet with painful M2 lesions under farm conditions, with lesion detection as ultimate goal. Secondary objectives were to determine the association between IRT from washed feet and M2 lesions, and between IRT from unwashed and washed feet and the presence of any DD lesion. A total of 641 hind feet were given an M-score and IRT images of the plantar pastern were captured. Multivariable logistic regression analyses were done with DD status as dependent variable and maximum infrared temperature (IRTmax), lower leg cleanliness score and locomotion score as independent variables, and farm as fixed effect. To further our understanding of IRTmax within DD status, we divided IRTmax into two groups over the median value of IRTmax in the datasets of unwashed and washed feet, respectively, and repeated the multivariable logistic regression analyses. Higher IRTmax from unwashed hind feet were associated with M2 lesions or DD lesions, in comparison with feet without an M2 lesion or without DD, adjusted odds ratio 1.6 (95% CI 1.2–2.2) and 1.1 (95% CI 1.1–1.2), respectively. Washing of the feet resulted in similar associations. Dichotomization of IRTmax substantially enlarged the 95% CI for the association with feet with M2 lesions indicating that the association becomes less reliable. This makes it unlikely that IRTmax alone can be used for automated detection of feet with an M2 lesion. However, IRTmax can have a role in identifying feet at-risk for compromised foot health that need further examination, and could therefore function as a tool aiding in the automated monitoring of foot health on dairy herds.

Published: January 2023

Aim

To assess contemporary in-hospital management of octogenarians and nonagenarians with ureteral calculi.

Materials and methods

Review of patients aged ≥80 years hospitalized due to ureteral calculi. Data was extracted from eight Austrian centers of urology. Stone and patient related data were recorded. Treatment patterns in acute and elective settings were assessed.

Results

A total of 759 patients hospitalized with ureteral calculi were analyzed. Out of them, 643 were octogenarians (80-89years) and 116 nonagenarians (90–99 years). In an acute setting, simple de-obstruction with urinary diversions outnumbered active stone treatments like URS and SWL (62.6% vs. 26.9% vs. 10.5%). Decision making whether patients underwent active stone treatment was driven by stone location (OR = 0.28, p<0.0001), impaired renal function (OR = 0.28, p = 0.01) and indwelling urethral catheters (OR = 0.23, p = 0.01) but not by age or extend of mobility (all p>0.05). In elective settings, 81.5% of procedures were active stone treatments–mainly URS (76.9%), while DJ stent or nephrostomy replacements were noted in 14.2% and 4.3%. Octogenarians (OR = 14, p<0.0001) and patients capable of walking (OR = 4.51, p = 0.01) had significantly higher odds of receiving active stone. Stone free rates and complications rates with URS were similar between octogenarians and nonagenarians (p = 0.98 and p = 0.58).

Conclusion

In acute settings, age and extend of mobility were not found to be independent predictors for active stone treatment. In elective settings, after having received urinary diversions, reduced mobility and nonagenarians were less likely to undergo stone removal treatments. Safety and efficacy of URS seems to be similar in octogenarians and nonagenarians.
Analyzing time-varying trip distributions with a random-effect spatial OD dependence model
Authors: Ni Linglin , (Cara) Wang Xiaokun , (Michael) Chen Xiqun , Zhang Dapeng
Published: January 2023

This paper proposes a random-effect spatial OD (origin-destination) dependence model to investigate varying trip distributions over time. By proposing a maximum likelihood estimation with spectral decomposition methods, the effects of spatial dependences and the unobservable zonal heterogeneity at the origin and destination can be estimated simultaneously. A series of numerical experiments and a real-world trip distribution study with cellular signaling data collected in Hangzhou, China, are conducted. This paper enriches the existing literature by developing (1) an innovative specification to allow for random effects in existing spatial OD dependence models; (2) an innovative estimation method to obtain the values of parameters and improve model fittings; and (3) a set of numerical experiments and an empirical trip distribution analysis that jointly captures spatial effects (spatial interaction and spatial OD dependences), and the unobservable zonal heterogeneity. This paper can equip policymakers with an effective tool for analyzing the OD travel flow over time which is a groundwork for making appropriate transportation policies.
Usefulness of muscle ultrasound in appendicular skeletal muscle mass estimation for sarcopenia assessment
Authors: Baek Seol-Hee , Sung Joo Hye , Park Jin-Woo , Son Myeong Hun , Lee Jung Hun , Kim Byung-Jo
Published: January 2023

The measurement of skeletal muscle mass is essential for the diagnosis of sarcopenia. Muscle ultrasonography has emerged as a useful tool for evaluating sarcopenia because it can be used to assess muscle quality and quantity. This study investigated whether muscle ultrasonography is effective for estimating appendicular skeletal muscle mass (ASM) and screening for sarcopenia. This study prospectively enrolled 212 healthy volunteers aged 40–80 years. ASM was measured using the bioelectrical impedance analysis. Muscle thickness (MT) and echo-intensity (EI) were measured in four muscles (biceps brachii, BB; triceps brachii, TB; rectus femoris, RF; biceps femoris, BF) on the dominant hand. A hold-out cross-validation method was used to develop and validate the ASM prediction equation. In the model development group, the ASM prediction equations were deduced as follows: estimated ASM for men (kg) = 0.167 × weight (kg) + 0.228 × height (cm) + 0.143 × MT of BF (mm)– 0.822 × EI to MT ratio of BB– 28.187 (R2 = 0.830) and estimated ASM for women (kg) = 0.115 × weight + 0.215 × height (cm) + 0.139 × MT of RF–0.638 × EI to MT ratio of BB– 23.502 (R2 = 0.859). In the cross-validation group, the estimated ASM did not significantly differ from the measured ASM in both men (p = 0.775; intraclass correlation coefficient [ICC] = 0.948) and women (p = 0.516; ICC = 0.973). In addition, multiple logistic regression analysis revealed that the ratios of EI to MT in the BF and RF muscles in men and MT in the BB muscle in women could be valuable parameters for sarcopenia screening. Therefore, our study suggests that muscle ultrasound could be an effective tool for estimating ASM and screening sarcopenia.
No effect of monetary reward in a visual working memory task
Authors: van den Berg Ronald , Zou Qijia , Li Yuhang , Ma Wei Ji
Published: January 2023

Previous work has shown that humans distribute their visual working memory (VWM) resources flexibly across items: the higher the importance of an item, the better it is remembered. A related, but much less studied question is whether people also have control over the total amount of VWM resource allocated to a task. Here, we approach this question by testing whether increasing monetary incentives results in better overall VWM performance. In three experiments, subjects performed a delayed-estimation task on the Amazon Turk platform. In the first two experiments, four groups of subjects received a bonus payment based on their performance, with the maximum bonus ranging from $0 to $10 between groups. We found no effect of the amount of bonus on intrinsic motivation or on VWM performance in either experiment. In the third experiment, reward was manipulated on a trial-by-trial basis using a within-subjects design. Again, no evidence was found that VWM performance depended on the magnitude of potential reward. These results suggest that encoding quality in visual working memory is insensitive to monetary reward, which has implications for resource-rational theories of VWM.
Identification of ARMH4 and WIPF3 as human podocyte proteins with potential roles in immunomodulation and cytoskeletal dynamics
Authors: De Luca Francesco , Kha Michelle , Swärd Karl , Johansson Martin E.
Published: January 2023

The podocyte is a specialized cell type critically involved in maintaining the selective filtration barrier of the kidney. Podocytes are primary or secondary targets for a multitude of kidney diseases. Despite intense investigation, the transcriptome and proteome of human podocytes remain incompletely characterized. Here, we analyzed publicly available RNA-Seq data from human kidneys (n= 85) to computationally identify potential novel podocyte markers. For confirmation, we used an online histology resource followed by in-house staining of human kidneys and biochemical fractionation of glomeruli. Initial characterization of the novel podocyte transcripts was performed using viral overexpression and mRNA silencing. Several previously unrecognized gene products were identified that correlated to established podocyte markers on the RNA level and that were histologically localized to podocytes.ARMH4(a.k.a. UT2 or C14orf37) andWIPF3(a.k.a CR16) were among the hits. We show that these transcripts increase in response to overexpression of the podocyte transcription factorLMX1B. Overexpression of ARMH4 from low endogenous levels in primary kidney epithelial cells reduced the release of the inflammatory mediators IL-1B and IL-8 (CXCL8). The opposite effect was seen in mature human podocytes when ARMH4 was silenced. Overexpression of WIPF3 stabilized N-WASP, known to be required for maintenance of podocyte foot processes, and increased cell motility as shown using a scratch assay. Moreover, data from normal and diseased human kidneys showed that ARMH4 was downregulated in glomerular pathologies, while WIPF3 remained constantly expressed. ARMH4 and WIPF3 are new potential markers of human podocytes, where they may modulate inflammatory insults by controlling cytokine release and contribute to cytoskeletal dynamics, respectively.
A study protocol for the validation of a prognostic model with an emphasis on modifiable factors to predict chronic pain after a new episode of acute- or subacute nonspecific idiopathic, non-traumatic neck pain presenting in primary care
Authors: Verwoerd Martine J. , Wittink Harriet , Maissan Francois , van Kuijk Sander M. J. , Smeets Rob J. E. M.
Published: January 2023

Background

The primary objective of this study is to identify which modifiable and non-modifiable factors are independent predictors of the development of chronic pain in patients with acute- or subacute nonspecific idiopathic, non-traumatic neck pain, and secondly, to combine these to develop and internally validate a prognostic prediction model.

Methods

A prospective cohort study will be conducted by physiotherapists in 30 primary physiotherapy practices between January 26, 2020, and August 31, 2022, with a 6-month follow-up until March 17, 2023. Patients who consult a physiotherapist with a new episode of acute- (0 to 3 weeks) or subacute neck pain (4 to 12 weeks) will complete a baseline questionnaire. After their first appointment, candidate prognostic variables will be collected from participants regarding their neck pain symptoms, prior conditions, work-related factors, general factors, psychological and behavioral factors. Follow-up assessments will be conducted at six weeks, three months, and six months after the initial assessment. The primary outcome measure is the Numeric Pain Rating Scale (NPRS) to examine the presence of chronic pain. If the pain is present at six weeks, three months, and six months with a score of NPRS ≥3, it is classified as chronic pain. An initial exploratory analysis will use univariate logistic regression to assess the relationship between candidate prognostic factors at baseline and outcome. Multiple logistic regression analyses will be conducted. The discriminative ability of the prognostic model will be determined based on the Area Under the receiver operating characteristic Curve (AUC), calibration will be assessed using a calibration plot and formally tested using the Hosmer and Lemeshow goodness-of-fit test, and model fit will be quantified as Nagelkerke’s R2. Internal validation will be performed using bootstrapping-resampling to yield a measure of overfitting and the optimism-corrected AUC.

Discussion

The results of this study will improve the understanding of prognostic and potential protective factors, which will help clinicians guide their clinical decision making, develop an individualized treatment approach, and predict chronic neck pain more accurately.
Does the bankrupt cheat? Impact of accounting manipulations on the effectiveness of a bankruptcy prediction
Authors: Mućko Przemysław , Adamczyk Adam
Published: January 2023

The aim of this article is to answer the question whether the unreliability of the Altman bankruptcy prediction model may be caused by manipulations in financial statements. Our study was carried out on a group of 369 bankrupt Polish companies, with the research period covering the years 2011–2020. In the study, we divided the companies into two groups: those correctly classified by Altman’s model as at risk of bankruptcy, and companies for which the model did not indicate a significant bankruptcy risk. Using a logit model, we tested whether the probability of companies being correctly classified as failed depends on the risk of a manipulation of financial statements. We use Benford’s law to measure the risk of a manipulation of financial statements. We also repeated our study using panel data models. Our analyses show that the manipulation of financial statements is not the cause of the inaccurate predictions of the Altman model. On the contrary, the results of the analyses indicate that manipulations occurs for companies with a lower Z-score and therefore a worse financial situation. This means that a deterioration in the quality of financial statements can be a signal of an increasing probability of bankruptcy.
Incidence and predictors of loss to follow-up among women on option B+ PMTCT program in northwest Ethiopia. A retrospective follow-up study

Published: January 2023

Background

Loss to follow-up from lifelong antiretroviral therapy continued to be a major challenge affecting virtual elimination of mother-to-child transmission of human immunodeficiency virus, especially in Sub-Saharan Africa. Although there was a study conducted in Ethiopia, loss to follow-up was not clearly defined and some important variables were not addressed. Thus, this study was conducted to determine the incidence of loss to follow-up and its predictors among women on option B+ lifelong antiretroviral therapy program in Pawi district health facilities, northwest Ethiopia.

Methods

An institutional-based retrospective follow-up study was conducted among 365 women who were enrolled for option B+ prevention of mother-to-child transmission service between June 2013 and March 2021 in Pawi district health facilities. A standard pretested checklist was used to extract data from all eligible women’s records. The Kaplan–Meier survival curve for estimating survival probability and Cox proportional hazards model to identify independent predictors of loss to follow-up were employed after checking for proportional hazards assumptions using STATA-14 statistical software.

Result

The overall incidence of loss to follow-up was 12.04 (95% CI: 9.50, 15.20) per 1000 person-months of observation time. Residing outside the catchment area (adjusted hazard ratio (AHR): 3.08, 95% CI: 1.59, 5.98), lactating at enrollment (AHR: 2.43, 95% CI: 1.24, 4.77), living in a sero-discordant relationship (AHR: 2.5, 95% CI: 1.13, 5.53), lack of sero-status disclosure (AHR: 2.59, 95% CI: 1.15, 5.85), new enrollment to lifelong antiretroviral therapy (AHR: 2.07, 95% CI: 1.05, 4.11), and fair (AHR: 2.69, 95% CI: 1.2, 6.04) or poor (AHR: 5.78, 95% CI: 2.76, 12.12) antiretroviral drug adherence level were independent predictors of loss to follow-up.

Conclusion

We found a higher incidence of loss to follow-up relative to previous studies in Ethiopia. Thus, strengthening adherence support interventions, and effective counseling on sero-status disclosure and male partner involvement are important to retain women in care.
Percursos nas Ciências da Educação: Lugar para a Utopia
Authors: Damião Maria Helena
Published: January 2023

Este livro surgiu do encontro entre pessoas que, desde há muito, colaboram na formação de professores e de educadores, afectas a Centos de Formação, Universidades e Centros de Investigação. Cada uma delas entende, à sua maneira, que a utopia não pode ser afastada da Educação, sob pena de a destituir do seu sentido humano e humanizante. Contudo, um discurso contemporâneo de diversa proveniência, veiculando a premência de mudar radicalmente a Escola, bem como a urgência de inovar os seus propósitos, procedimentos e atores, tende a afastar a utopia do horizonte educativo, fazendo, em paralelo, aproximar a distopia.
Com este problema em mente, decidiram organizar um ciclo de conferências, onde ele pudesse ser pensado à luz da filosofia, da ética, da antropologia, da história, da psicologia, e da pedagogia. O percurso (ou percursos) que estas disciplinas, tão marginalizadas nesse discurso, têm feito constitui um precioso apoio para decidir o futuro da educação, o qual, ao contrário, do que se insiste em dar a entender, não está determinado e fechado; antes está, como sempre esteve, aberto, tomando a orientação que entendermos, no presente, imprimir-lhe.

How do we use leadership to keep our nurses?
Authors: Goens Becky
Published: January 2023

Title: How do we use leadership to keep our nurses?

Introduction: We are currently experiencing a healthcare crisis of understaffed environments that impede evidence-based patient care.

Background: The nursing profession is facing some of the highest turnover and shortage rates in healthcare as registered nurses plan to leave their positions more than any other healthcare professional. Although retention is a multifaceted issue evidence has shown leadership to have positive influences.

Results: Transformational leadership encourages an environment in which registered nurses intend to stay in their positions and are less likely to leave.

Conclusion: Nursing managers and members of leadership need to examine their leadership capabilities introspectively to assess factors pertaining to the dissemination of their leadership which could encourage nurses to leave their positions or the profession.
A Study on the Method of Presenting Grammar Items in Korean Language Education
Authors:   The Society Of Modern Grammar, Yoo Haejun
Published: January 2023

The grammar covered in Korean language education is different from the grammar category covered in Korean language education for native speakers. In this regard, although the subject of education is different, there are two positions that the grammar categories required for education should be set differently because the subject of education is different from the position that the grammar categories taught in schools should be unified equally. Just by looking at the position on Korean grammar, one can see differences in perception of Korean language education for foreigners and Korean language education for native speakers.. In this study, all of these differences cannot be summarized. However, by mentioning these discussions, I think it can be an opportunity to think about setting the category of educational grammar necessary for Korean language education. For this reason, this paper examines the categories and forms of grammar items covered in Korean language education and summarizes the terms used as references.
Charter schools after three decades: Reviewing the research on school organizational and instructional conditions
Authors: Dallavis Julie W. , Berends Mark
Published: January 2023

Charter school policies have focused on improving three aspects of schools—autonomy, innovation, and accountability—with the intention of promoting advances in curriculum, instruction, and learning that lead to better student outcomes. However, most research on charter schools tends to neglect school organizational and instructional conditions. Overall, reviews show that charter schools have inconsistent effects on student achievement scores, a finding that masks heterogeneous effects among different types of charter schools, operators of charter schools, and authorizers of charter schools and the organizational and instructional conditions under which they operate. This systematic review of the literature focuses on what we know about the organization of charter schools and the resources—material, human, and social as well as professional development and teaching practices—within them. We end by identifying gaps where more research is needed.
Variation in speech tempo and its relationship to prosodic boundary occurrence in two speech genres
Authors: Volín Jan
Published: January 2023

The present study focuses on two problems connected with speech tempo. First, earlier research has been prevalently concerned with central tendencies while variation was mostly perceived as an auxiliary result. We believe, however, that information about data dispersion is essential for proper modelling and experiment design in the field of temporal structure of speech. Therefore, the present study provides reference values for some of the tempo metrics of variation that pertain to (a) between-genre differences, (b) within-genre differences, (c) inter-speaker differences, and (d) intra-speaker differences. Second, we tested the claim that faster tempi lead to fewer prosodic breaks in spoken texts. This claim had been supported by studies where a respondent was asked to produce the same text at various rates. We, on the other hand, pose a question of the number of prosodic breaks in speakers who are fast or slow inherently. The material used in the study represents two genres: poetry reciting and news reading, and we obtained recordings from 24 speakers in each genre. Apart from providing the quantifications, the outcomes suggest, for example, that the predisposition of individual speakers to produce fast or slow tempi differs between the two genres. The fastest speakers in news reading were not necessarily the fastest in poetry reciting. This result points at specific behaviour in different situations and invites caution concerning the idea of hard-wired speaking stereotypes in individuals. Also, the correlation between speakers’ rates and the number of phrases they produced was significant only in news reading, not in poetry reciting. This result was corroborated by greater variation in prosodic boundary placement in news reading. In addition, the results offer an insight into the relationship between articulation rate and speech rate, together with the comparison of measurements in syllables per second and phones per second. The latter can be of interest since Czech (the language of the material) belongs to languages with a complex syllabic structure.
‘You’re ignoring the truth’ – Fatih Akın’s Polluting Paradise (2012) and Eco-Trauma Cinema
Authors: Domalewski Adam
Published: January 2023

The paper provides an analysis of the documentary Polluting Paradise (2012) by Fatih Akın within the context of eco-trauma cinema. The movie depicts ecological contamination as a social problem and mutual catastrophe, exactly as the theory of eco-trauma cinema suggests. Through a careful observational mode of filmmaking that characterize Polluting Paradise, the mechanisms that are responsible for environmental pollution are being scrutinized. The author argues that the movie combines documentary techniques with melodramatic structures for the sake of the audience’s emotional involvement. The article concludes with a reflection on the cinematic rhetoric used by Akın to affect the viewers.
Comprehension and Preference of AAC Symbols in Elementary School Students with Developmental Disabilities
Authors: Ahn So Hyun , Lee Su Hyang , Na Ji Young ,   Korean Society of Augmentative and Alternative Communication
Published: January 2023

Background and Objectives: Children with Complex Communication Needs(CCN) can use Augmentative and Alternative Communication(AAC) to support their communication. AAC systems include graphic symbols and it is important that they are comprehensible by these children. DAS (Developmentally Appropriate Symbols) were developed for the children, but there is very limited evidence on comprehension and preference of this symbol set by children with developmental disabilities. Therefore, this study aimed to investigate comprehension and preference of AAC graphic symbols including DAS, Ewha-AAC symbols, and wetok. Method: Ten elementary school students with developmental disabilities(DD group) and 10 children without disabilities (language age matching: LA group) participated in this study. Seven abstract words (Eat, come, big, none, who, what, up) were selected and different AAC symbol sets(DAS, Ewha-AAC symbols, wetok) for these words were presented to the participants. After an instruction session on the meanings of the symbols, their comprehension and preference data were collected. Results: The results showed significant differences between the participant groups with higher accuracy from children without disabilities. The results also revealed that most of the DD group preferred DAS, while most of the other group preferred wetok. Conclusion: From the results of this study, it is suggested that comprehension and preference for DAS, Ewha-AAC symbols, and wetok were different in children with/without developmental disabilities. Therefore, it is recommended that AAC symbol design and selection should be based on children’s characteristics and profile, particularly for children with developmental disabilities.

Background and Objectives: Although studies of vocabulary for application in augmentative and alternative communication (AAC) intervention are regularly conducted, domestic studies targeting older adults are rare. This study aims to increase the efficiency of vocabulary selection for AAC intervention by providing a list of vocabulary used frequently among older adults during storytelling. Method: Three storytelling tasks (narration of personal experiences, explanation, and story composition) were assigned to 12 older adults (5 male, 7 female) in their 70s and 80s and their speech was collected. The speech produced was then transcribed to analyze the high-frequency vocabulary, proportion of total speech occupied by core vocabulary, and proportions of core vocabulary occupied by structure and content words. Results: The type of task influenced the high-frequency vocabulary appearing in the storytelling tasks. The number of total words (NTW) was 15,574, while the number of different words (NDW) was 930. Of these total words 283 were core vocabulary, occupying 78.3% of the total words, and content words (78.4%) occupied a greater proportion of core vocabulary than structure words (21.6%). Conclusion: This study provides a list of core vocabulary used during storytelling by older adults without disabilities, a population lacking in clinical evidence, and in the examination of the characteristics of vocabulary usage to be considered when selecting vocabulary for AAC interventions in older adults with complex communication needs.

Published: January 2023

Background and Objectives: This study examined the effect of the SON-DAM on communication response behavior in three students with visual and multiple disabilities who have difficulty using spoken language. Method: This study used a multiple baseline probe technique. The experiment was conducted in the order of target vocabulary selection, research assistant teacher training, baseline, intervention and maintenance. The intervention consisted of vocabulary acquisition training in a classroom environment and functional vocabulary training in a natural environment. Results: All three students showed positive changes in their communication response behaviors after communication intervention using SON-DAM. Compared to the baseline, the frequency of communication response behaviors increased, and various communication response behavior patterns were used. The increased frequency of communication response behaviors of the three students was maintained at a higher level than the baseline after the communication intervention was finished. Conclusion: These results suggest that communication intervention using SON-DAM has positive effects on the frequency and maintenance of communication response behaviors of students with visual and multiple disabilities. This study confirmed the possibility of developing communication skills for students with visual and multiple disabilities whose appropriate communication means were not established until adolescence.

Published: January 2023

Background and Objectives: In people with cerebral palsy in the pre-intentional stage, parents are the main communication partners and they need to understand the communication characteristics of their children and how to facilitate communication development with Augmenetaive and Alternative Communication(AAC). However, studies on AAC parental education for parents with children with cerebral palsy in the pre-intentional communication stage are limited. Therefore, this study aimed to conduct AAC parental education for parents with children with cerebral palsy in the pre-intentional communication stage and to verify its effect on the parents’ and children’s communication behavior Method: Parental education was conducted for mothers of children with cerebral palsy in the pre-intentional communication stage, and the results were analyzed by conducting pre and post-test before and after education. Results: After AAC parental education, the post-test results of communication behavior of mothers and children with disabilities were higher than those of the pre-test. Conclusion: First, AAC parental education had a positive effect on mother’s communication behavior and helped to develop confidence in her interaction with the children. Second, the improvement of the mothers’s communication intervention skills facilitated the communication behavior of children with disabilities who are AAC users. Third, the contents of various parental education programs facilitated the active participation of mothers and increased educational satisfaction.

Published: January 2023

This research paper represents the estimation and reduction of eddy current loss in a Magnetic Fault Current Limiter (MFCL). The nonlinear model of the device is established using electromagnetic coupled circuit supported by Finite Element Model. The current limiting performance of the MFCL is investigated by simulation study as well as laboratory testing. It is further observed that a significant amount of eddy current loss takes place inside the core and permanent magnet of the device. Different methods (shorting ring, lamination of permanent magnet and variation of magnet length) are proposed to reduce the eddy current. The advantages and disadvantages of these methods are discussed. Some design modifications are also proposed to minimize the temperature rise caused by the eddy current.
Kelly criterion and fractional Kelly strategy for non-mutually exclusive bets
Authors: Jacot Benjamin P. , Mochkovitch Paul V.
Published: January 2023

This paper examines how the Kelly criterion, a strategy for maximizing the expected log-growth of capital through informed betting, can be applied to non-mutually exclusive bets. These are bets where there is no one-to-one correspondence between the bets and the possible outcomes of the game. This type of situation is common in horse racing, where multiple types of bets are available for a single race. The paper begins by providing a theoretical overview of the Kelly betting strategy and then discusses how it can be extended to non-mutually exclusive bets. A new formulation of the fractional Kelly strategy, which involves betting a fixed fraction of the amount suggested by the Kelly criterion, is also presented for this type of scenario.
On a locally compact monoid of cofinite partial isometries of ℕ with adjoined zero

Published: January 2023

Let 𝒞ℕ be a monoid which is generated by the partial shift α : n↦n +1 of the set of positive integers ℕ and its inverse partial shift β : n + 1 ↦n. In this paper we prove that if S is a submonoid of the monoid Iℕ∞ of all partial cofinite isometries of positive integers which contains Cscr;ℕ as a submonoid then every Hausdorff locally compact shift-continuous topology on S with adjoined zero is either compact or discrete. Also we show that the similar statement holds for a locally compact semitopological semigroup S with an adjoined compact ideal.

Published: January 2023

This paper aims to determine the level of occupational stress associated with the work-related factors of agents and supervisors of a security company in Lima. A quantitative, non-experimental, correlational and cross-sectional approach was used. The sample consisted of 541 agents and supervisors of a private security company in Lima. A survey was used as the data collection technique. The results showed that work-related factors “incentives” (p < 0.001), “contract type” (p < 0.001), “/compensation” (p < 0.001) and “job stability” (p < 0.001) are related to occupational stress. Stress is related to various work-related factors such as incentives, contract type, compensation and job stability of security agents and supervisors of a private security company in Lima.
Modelo de decisiones racionales y metaracionales para la gestión de organizaciones. Enfoque exploratorio transdisciplinario para la resolución de problemas en la dirección científica
Authors: Acevedo Borrego Adolfo Oswaldo , Linares Barrantes Martha Carolina
Published: January 2023

In academy, which includes scientific management or industrial engineering, decisions in organizations and the techniques used are fully based on rational criteria, including various techniques derived from learning from experience, called intuitive or heuristic. Academia does not consider approaches that are not framed within the rational criteria, since it considers that they do not exist or are irrelevant. The objective of the study is to develop a different approach to decision making under a transdisciplinary perspective and through the design of a conceptual model of decisions that considers the range of rational and meta-rational decisions in all organizational scenarios where problems are solved. It has been found that professionals define the decision criteria according to the perceived scenario: if it is simple and concrete, the technique is systematic and focused; if it is undefined or amorphous, the technique is soft with options; if the problem is complex, emotional criteria, beliefs and atavisms are considered, or creative and heuristic options are invented. The transdisciplinary perspective allows the inclusion of criteria and methods of problem solving not considered by academia, which enriches the praxis of the profession in the management of organizations.

In Peru, the textile industry represents a very important sector due to its significant contribution to the national GDP. All 398 thousand workers in this sector are prone to suffer from musculoskeletal disorders (MSDs), since the operation of machinery and handling of materials involves prolonged repetitive movements, causing strain on the body. This research aims to reduce the risk level of MSDs in a garment manufacturing SME. Therefore, an ergonomic method was developed based on REBA and RULA integration, which also proposes preventive and corrective measures. A initial evaluation was performed based on the observed postures of the operators to identify the risk levels; subsequently, the evaluation was repeated upon the implementation of the method in order to estimate its effectiveness. As a result, there was an improvement of 44.97%, that is, the level of risk to which the workers are exposed was reduced, demonstrating that the method is useful for garment manufacturing SMEs.
