Quasi-experimental designs for causal inference: Addressing threats to validity from a graphical models perspective
Authors: Sheehan Patrick , Kwon Muwon , Steiner Peter M.
Published: September 2024

In the developmental sciences, and social sciences in general, we are often interested in determining the effect of a specific intervention on a specific outcome. While randomized control trials allow for the investigation of such causal questions, the randomization of participants into particular conditions is often infeasible or unethical. Quasi-experimental designs provide an alternative, in which participants select their preferred condition but researchers retain some control over the implementation of a treatment. In this chapter, we use causal graphs to introduce the rationale of specific quasi-experimental designs and to discuss their causal assumptions. Causal graphs are a formal language for explicitly stating subject matter theory about a causal process and its implied causal assumptions. Additionally, we discuss potential validity threats in these designs that can reduce the credibility of causal claims.

Authors: Arafat Easin , Arafat Easin
Published: September 2024

After a protein has been translated by a ribosome, it may go through a processknown as post-translational modification (PTM). PTM is an alteration to one or moreamino acids in a protein that happens after it has been translated. They are also regarded as a significant component of cell signaling and networking pathways. Methylation is often considered to be one of the most significant forms of PTMs. Methylationis playing a crucial impact in the maintenance of the stability, dynamic equilibrium,and remodeling of chromatins and causes certain abnormalities in cells towards severeillnesses. Identifying methylation in the presence of a methylation marker can be doneusing methylation-specific antibodies, mass spectrometry, or radioactive labeling.However, traditional procedures required additional expenses and time-consumingspecialized equipment. In this study, we demonstrate the use of sequential-basedfeatures, which are computationally less expensive to produce. We developed a computational model for the prediction of methylation PTM sites that incorporates bothevolutionary sequence-based features and structural-based information. We also useda SMOTETomek-based hybrid sampling method at particular ratios in conjunctionwith features based on mutual information. Following that, The optimal collection offeatures including permutation and Gini feature importance was applied to multiplealgorithms to predict the result, and the final model was trained using an extremegradient boosting (XGBoost) classifier. With 10-fold cross-validation and an independent test set, our model achieves an AUC-ROC score of 0.94 and 0.90 for lysinemethylation sites, demonstrating promising performance. Our proposed techniquesignificantly outperforms and beats the independent models by a wide margin. Weanticipate that the higher performance of our model will benefit researchers involvedin the identification of PTM methylation sites. Our model is easily accessible for useas a standalone predictor at https://github.com/arafatro/KmethPred.

Authors: Halim Mustabir
Published: September 2024

The material object in this research is one of Najib Mahfudz's collection of stories with the title "Si Malang", which is taken from a story collection book entitled "Bisik Bintang", the formal object of which is deconstruction presented by Derrida. This article offers a new reading and meaning of the story of the character Hasan El-Dahshan. As a variety of literary sociology theory, Derrida's deconstruction has a theoretical category that rejects the establishment of all forms of logocentric structures understood by most people where there is only black and white or only right and wrong. Therefore, this theory tries to turn this around, so that it has a wider variety of colors and does not just focus on one point that is always considered correct by society. The research in this paper comes from the literature. The method used is deconstruction through three stages: the first stage is verbal reading, the second stage is textual reading, and the third is linguistic reading. The results of this research found a structure that was considered established and considered valid, which was then carried out by reversing the hierarchy by reviewing it again to see the form of instability of meaning through the multiplicity of characters in the short story, thus producing new meaning through the multiplication of identities, showing the destruction of the absoluteness of identities that are only understood as powerful, evil, powerful, and powerless in the story.Objek materi dalam penelitian ini adalah salah satu dari kumpulan cerita Najib Mahfudz dengan judul “Si Malang” yang diambil dari buku kumpulan cerita berjudul “Bisik Bintang”, objek formalnya adalah dekonstruksi yang dibawakan oleh Derrida. Tulisan ini menawarkan pembacaan dan pemaknaan baru atas cerita tokoh Hasan El-Dahshan. Sebagai ragam teori sastra sosiologi, dekonstruksi Derrida memiliki kategori psikologi yang menolak kemapuan dari segala bentuk Struktur logosentris yang dipahami oleh kebanyakan orang yang mana hanya ada hitam dan putih atau hanya ada benar dan salah. Oleh karena itu teori ini mencoba memutarbalikkan hal tersebut agar lebih memiliki ragam warna dan tidak hanya fokus pada satu titik yang selalu dianggap benar oleh masyarakat. Penelitian dalam tulisan ini berasal dari kepustakaan, Adapun penggunaan metode berupa dekonstruksi melalui tiga tahapan, yaitu tahap pertama berupa pembacaan verbal, tahap kedua berupa pembacaan tekstual, dan ketiga berupa pembacaan secara linguistik. Hasil dari penelitian ini ditemukan struktur yang sudah dianggap mapan dan dianggap absah, yang kemudian dilakukan pembalikan hierarki dengan menelaah kembali untuk melihat bentuk ketidakstabilan makna melalui multiplitas tokoh yang berada di dalam cerpen sehingga menghasilkan pemaknaan baru melalui multiplikasi identitas, menunjukkan hancurnya kemutlakan identitas yang hanya menjadi orang yang memahami kekuasaan, jahat, kuat, dan tidak berdaya pada cerita tersebut.

Published: September 2024

Propolis is a natural bee product used as a therapeutic agent for centuries. Propolis extracts are natural resources that attract the attention of scientists looking for new components due to the insufficiency of existing drugs. In current study, antiviral and antimicrobial activity of propolis water extracts prepared from three different raw propolis samples collected from Northeast of Türkiye (Ardahan, Rize, and Trabzon) were investigated. The total flavonoid contents (TFC) and total phenolic content (TPC) of the extracts were measured. It was determined that TPC and TFC ranged from 5.87±0.36 to 20.47±1.46 mg GAE g-1, and 0.48±0.04 to 2.10±0.22 mg QUE g-1, respectively. The antimicrobial activity of the extracts against 14 microorganisms (Bacillus cereus ATCC14579, Staphylococcus aureus ATCC 25923, Enterococcus faecalis ATCC 29212, Bacillus subtilis ATCC 6633, Pseudomonas aeruginosa ATCC 27853, Acinetobacter haemolyticus ATCC 19002, Escherichia coli ATCC 25922, Salmonella typhimurium ATCC 14028, Enterobacter aerogenes ATCC 13048, Mycobacterium smegmatis ATCC 607, Klebsiella pneumoniae ATCC 13883, Chromobacterium violaceum ATCC 12472, Candida parapsilosis ATCC 22019, and Candida albicans ATCC 10231) and their effect against the Pseudomonas aeruginosa biofilm were investigated. Additionally, anti-quorum sensing and anti-swarming activities of the extracts were tested. The antiviral activity of the extracts was examined against Herpes simplex virus type 1 (HSV-1) by MTT and qRT-PCR methods. The water extracts of propolis samples did not show antimicrobial, anti-swarming, anti-quorum sensing, and anti-viral activities. However, extracts were found to have strong anti-biofilm activities. The results show that aquatic propolis extracts can be evaluated in the treatment of biofilms.

Egypt is one of the important countries in terms of bee diversity in Northern Africa. The Eastern part of the country has been the subject of several studies over the last decade, especially in comparison to the Western part. In this work, we explore the diversity of solitary bees in the Alexandria Governorate, specifically in the Al Hawaria region (30°57'13" N, 29°40'27" E), based on two years of research conducted in 2021 and 2022. A total of 51 species were identified in the region: 25 species of Apidae, 16 of Megachilidae, 5 of Andrenidae, 4 of Halictidae, and one species of Colletidae. Pollen grain identification from plants and some solitary bee species revealed the creation of reference slides for pollen grains from 32 flowering plant species (both crops and wildflowers) across 19 plant families. The plant family preferences were varied among different bee genera. The most commonly visited plant families were Asteraceae, Brassicaceae, and Fabaceae, which accounted for 58% of the total bee-attracting flora. The pollen spectrum from the Xylocopa aestuans (L. 1758) nest consisted of two pollen types, while the nest of Osmia sp. contained a single pollen type.

Teletrabajo y derechos relacionados con el uso de los medios digitales: derecho a la intimidad y a la protección de datos y derecho a la desconexión digital
Authors: Pérez Gázquez Isabel María
Published: September 2024

Introducción: Uno de los retos asociados al teletrabajo es la compleja delimitación entre el alcance de la potestad de control empresarial y el derecho a la intimidad y protección de datos de las personas trabajadoras y su derecho a la desconexión digital. Metodología: Se analiza el contenido de la normativa reguladora del teletrabajo y de los criterios jurisprudenciales que permiten interpretar y concretarla. Resultados: La genérica regulación de estos derechos obliga a acudir a la negociación colectiva para su concreción, ocasionando el riesgo de dejar vacío de contenido su ejercicio efectivo, en tanto en cuanto los convenios colectivos o acuerdos de empresa no son actualizados. Discusión: los derechos no son absolutos y exigen definir los criterios que permiten determinar su aplicación a cada caso concreto, de acuerdo con el principio de proporcionalidad, que ha de existir en todo caso. Conclusiones: resulta preciso instar a una mayor potenciación de la negociación colectiva y de la responsabilidad social corporativa para aumentar la eficacia de estos derechos y evitar que la potestad empresarial se convierta en un control injustificado, intrusivo y desproporcionado.

Published: September 2024

Introducción: Tras la irrupción de la inteligencia artificial (IA) en el ámbito educativo, la enseñanza se encuentra en un proceso de cambio y adaptación. Este estudio surge de la necesidad de comprender cómo el estudiantado universitario integra la IA en sus procesos de aprendizaje y qué percepciones tiene sobre su uso y regulación. Metodología: Utilizando una encuesta ad-hoc con preguntas cerradas, de escala Likert y abiertas, se recopiló información de una muestra casual de estudiantes. Los datos se han analizado con técnicas estadísticas de carácter exploratorio. Resultados: Los hallazgos muestran que más del 94% de los encuestados utiliza la IA, principalmente en generación y traducción de textos y elaboración de presentaciones. Los estudiantes valoran el aprendizaje sobre IA para mejorar su competitividad laboral, aunque las opiniones sobre su regulación varían: algunos prefieren no regular, mientras otros sugieren limitar su uso o promover habilidades no automatizables, como la creatividad y el análisis crítico. Conclusiones: Se destaca la necesidad de formación del profesorado, así como el rediseño de las actividades educativas para que integren la IA. Deberá realizarse desde una perspectiva ética y complementaria, aprovechando, por un lado, el potencial de la IA y evitando, por otro, reemplazar el aprendizaje del alumnado.

Lednevite, ideally Cu[PO3(OH)]·H2O, is a new mineral discovered at the 255 m level of the Murzinskoe Au deposit, Krasnoshchyokovskiy District, Altai Krai, Western Siberia, Russia. It forms spherulites up to 0.1 mm in diameter, composed of very thin fibers and grouped in aggregates up to 1.5 mm across. Lednevite overgrows philipsburgite crystals on a matrix of epidote-andradite skarn and quartz and associates with malachite, chrysocolla, kaolinite, goethite and P-bearing cornubite. The new mineral is transparent, has sky blue color, very pale blue streak and vitreous lustre. Cleavage is not observed. The Mohs’ hardness is ~3. Dmeas = 3.18(2) g cm–3, Dcalc = 3.196 g cm–3. The chemical composition of lednevite is (electron microprobe, wt.%; H2O by stoichiometry): CuO 40.20, ZnO 3.92, P2O5 36.29, As2O5 4.80, H2O 14.98, total 100.15. The empirical formula calculated on the basis of 3 H and 5 O apfu is (Cu0.91Zn0.09)Σ1.00[(P0.92As0.08)Σ1.00O3(OH)]·H2O. The crystal structure was refined by the Rietveld method to Rp = 0.0042, Rwp = 0.0061, Robs = 0.0354. Lednevite is monoclinic, space group P21/a, with a = 8.6459(6), b = 6.3951(4), c = 6.8210(5) A, β = 93.866(2)°, V = 376.28(4) A3 and Z = 4. The strongest lines of the powder X-ray diffraction pattern [d, A (I, %) (hkl)] are: 5.135 (100) (110), 4.648 (33) (011), 3.241 (28) (21-1), 3.095 (49) (211), 2.891 (27) (11-2), 2.775 (53) (112), 2.568 (29) (220). The new mineral is isotypic to the synthetic CuHPO4·H2O. Some optical and spectroscopic data, which could not be obtained on natural sample, were obtained from the synthesized material. The crystal structure of the synthetic analogue of lednevite was solved from single-crystal X-ray diffraction data and refined to R1 = 0.0173 for 1159 independent reflections with I 2σ(I). All positions of H atoms were determined. Lednevite is named for Vladimir Sergeevich Lednev, amateur mineralogist from Barnaul (Altai Krai) who collected the sample with the new mineral.

Published: September 2024

Halotrichite is a widespread mineral in post-volcanic environments and oxidation zones of ore deposits. Halotrichite is stable at temperature up to 70 °C; further heating leads to the formation of an X-ray amorphous phase I. There are reflections of millosevichite (prevailing) and mikasaite appearing in the range of temperatures 340–660 °C. Millosevichite and mikasaite are decomposing at temperatures 660 °C with the formation of an X-ray amorphous phase II. According to data of the synchronous thermal analysis, the transition from halotrichite into anhydrous sulfates is accompanied by the loss of H2O molecules, which makes about 42.9 wt %, the transition to the X-ray amorphous phase II is caused by the loss of SO3, which is ca. 37.4 wt %, associated with two endothermal effects. The thermal expansion of halotrichite is sharply anisotropic, the maximum expansion is determined by the shear deformations of the lattice in its monoclinic plane along the bisectrix of the obtuse angle β, and the minimum one – in the direction of strong S–O–Fe bonds inside [Fe(SO4)(H2O)5]0 complexes. The significant volumetric expansion of halotrichite (9(3)∙10-5 ºC-1) occurs due to the determing role of hydrogen bonds in composition of the crystal structure.

Published: September 2024

The rapid growth of amusement parks in Indonesia has elevated them to significant tourist hubs, prompting a detailed examination of visitor satisfaction within these settings. This study aims to analyze the satisfaction trends among tourists visiting the top 11 amusement parks in Indonesia and assess whether their ratings accurately reflect their satisfaction. Moreover, it investigates the factors influencing satisfaction levels, employing an adjusted rating method to dissect tourists' ratings and compare them with sentiment analysis results derived from provided reviews. While acknowledging the fluctuating performance of these destinations, with most showing signs of improvement, the study highlights that only 5 destinations within the sample exhibit comovement between adjusted ratings and sentiment analysis results. Furthermore, a closer inspection reveals that some destinations have successfully minimized the prevalence of negative sentiments expressed in reviews. However, there is still 1 destination that is of concern because it has decreased customer satisfaction as indicated by a decrease in score and the addition of negative sentiment.

Hypertension is one of the leading causes of morbidity around the world. Between 1990 and 2019, the number of people with hypertension doubled, rising from 650 million to 1.3 billion. Hypertension is defined as high blood pressure with a systolic pressure higher than 140 mmHg and a diastolic pressure higher than 90 mmHg on both measurements taken at a five-minute interval during a period of sufficient rest or calm. Stress is the leading cause of hypertension because it increases cortisol output by the adrenal glands, which leads to hypertension. This study is a literature review which includes completing a journal review applying comparative research methods. The results indicate that there is a link. Cortisol levels and stress levels are linked in hypertensive patients because when stressed, the body releases more stress hormones (adrenaline and cortisol), which activates the Renin Angiotensin Aldosterone System (RAAS), causing blood pressure increase..

Published: September 2024

Diversity plays a major role when a student is looking for a tutor to better understand some concepts or an entire course. In fact, algorithms for recommending potential tutors have to take into account several aspects of diversity that may be critical to successful tutoring. The tutor must have the appropriate competencies in the subject matter. In addition, he/she must be able to convey the knowledge and skills associated with the tutoring topic. Moreover, the personality traits of the tutee and the tutor can facilitate or hinder the learning process during tutoring. This study presents the experience of ‘SOS TUTORÍA UC’, a responsive web application aimed at facilitating academic assistance among students. Special emphasis is placed on the importance of incorporating dimensions of diversity that can inform the artificial intelligence algorithms of the potential tutor recommendation system. Indeed, competence in the topic tutored is the first diversity criterion for recommending more knowledgeable potential tutors. In addition, the tutee has to choose whether to look for tutors with personalities that are “different”, “similar” or “indifferent” to his or her own preferences for academic assistance on the specific topic. To achieve this, ‘SOS TUTORÍA UC’ is integrated with the WeNet platform, which provides user management services and user recommendation algorithms. The results of the testing of the recommendation system were positive with regard to the criterion of competence, while the criterion of personality should be addressed for improvement. In order to improve the tutor-tutee matching process, participants emphasized the importance of considering the criterion of personality traits in addition to competence. They also requested additional information and parameters to facilitate tutor selection.

BACKGROUND: Choosing appropriate complementary methods, such as exercise, along with taping methods may be effective in treating patients with kyphosis. OBJECTIVE: The present study aimed to examine the effect of different tape tensions/directions combined with corrective exercises on the degree of postural kyphosis in adolescents. METHODS: In this randomized controlled trial, 54 adolescents with postural kyphosis were assigned into three groups: No taping (control), I-shaped taping technique with 10% stretching force (Kinesiotape I), and I-shaped taping using facilitation technique with 40% stretching force (Kinesiotape II). Both groups in Kinesiotaping also received a V-shaped tape (10% stretching force). All participants received a similar comprehensive corrective exercise. Patients received the allocated interventions for 6 weeks and visited every two weeks at the clinic. Measurements were done using a flexible ruler, kyphometer, and photogrammetry. RESULTS: Between-group analyses revealed no significant differences between the study groups following the interventions (p> 0.05). However, the within-group analyses according to flexible ruler, Kyphometer, and Photogrammetry measurements indicated that exercise alone (control) [p= 0.011, p= 0.056, and p= 0.005, respectively], Kinesiotape I – exercise [p= 0.001, p= 0.002, p= 0.013, and respectively], as well as Kinesiotape II – exercise [p< 0.001, p< 0.001, and p< 0.001, respectively] significantly decreased the postural kyphosis degree except exercise alone using Kyphometer measurement. No adverse events were observed during the study. CONCLUSION: The findings of photogrammetry, flexible rulers, and photogrammetry similarly indicated that the corrective exercises with or without tape tension/directions significantly decreased the postural kyphosis degree in adolescents.
Development of an ANN-Based Technique for Inversion of Seismic Refraction Travel Times
Authors: Pourmirzaee Rashed , Hosseini Shahab
Published: September 2024

Non-uniqueness in the inversion of seismic data can be considered the main challenge for the application of such data. Prior information, such as downhole data, can be used to control this problem. However, in most cases, prior information is not available; accordingly, geophysicists/analysts have to suppose a primary model for the observed data and then find the final adequate layered earth model through trial and error. In this study, a new technique was developed based on the artificial neural network (ANN) for the inversion of seismic refraction data in the absence of prior information. In this regard, a sequential multilayer perceptron (SMLP) was proposed, which integrates the sequential information of the model parameters to predict a reasonable layered earth model. In fact, at first, a multilayer perceptron (MLP) (First-MLP) was trained by synthetic data; then, a layered earth model, i.e., the primary model, was predicted for the observed data. Next, using the primary model, a range for each of the model parameters, i.e., thickness and P-wave velocity, for each layer was defined. Subsequently, new synthetic samples were generated based on the determined ranges. Finally, using another MLP (Second-MLP), which was trained by the new synthetic samples, the final model for the observed data was estimated. The proposed method was also tested by employing different synthetic data with and without noise. Moreover, the SMLP inversion technique was used to analyze the experimental seismic refraction dataset at a dam construction site. The results for both synthetic and experimental data confirmed the reliability of the proposed SMLP inversion technique.
