O traumático e as disputas pela memória na cena pública brasileira: Marielle Franco e Borba Gato
Authors: Botini Zortea Giovanna , De Oliveira Alves Lucas , Campos Andrade Paula , De Andrade Gomes Marcela
Published: April 2023

Por meio de um método ensaístico, sustentado pela teoria psicanalítica e seus enlaces com as teorias decoloniais e sociais críticas, este artigo reflete sobre as disputas pela memória e as possibilidades de elaboração de traumas coloniais, analisando os simbolismos de duas experiências ocorridas na cena pública brasileira: a quebra da placa em homenagem à memória de Marielle Franco e a queima da estátua em homenagem à Borba Gato. Apontamos que a aparição destas duas figuras no espaço público, bem como o atentado a elas, instauram diferentes possibilidades de compreensão da história e de elaboração de traumas psicossociais. Concluímos que o atentado à placa de Marielle se trata de uma tentativa de apagar sua memória, bem como dos diversos grupos oprimidos (mulheres, LGBTQIA+, pessoas negras) simbolizados por ela, mantendo, assim, as repetições mórbidas oriundas dos traumas coloniais. Já o atentado à estátua de Borba, simbolismo da expansão bandeirante no país, tensiona uma história oficial que oblitera as violentas ações perpetradas pelo Estado e segmentos da sociedade civil.

Authors: Leonardo de Melo Pablo , Maria Grisi Velôso Thelma
Published: April 2023

Na história da humanidade, a loucura foi concebida de diversas formas. Atualmente a Reforma Psiquiátrica propõe a construção de um novo lugar social para a loucura, concebendo-a como sofrimento psíquico. Para compreender como os usuários de saúde mental a concebem, fizemos uma pesquisa com o objetivo de analisar como essas pessoas produzem sentidos sobre o sofrimento psíquico em vídeos de domínio público. Para desenvolver esta pesquisa, adotamos a perspectiva teórico-metodológica da proposta de estudo da produção de sentidos a partir da análise das práticas discursivas. Trata-se de uma investigação de natureza qualitativa, com caráter exploratório, para cujo desenvolvimento foi feito uma pesquisa documental. Foram utilizados os videodocumentários ‘A loucura entre nós’ e ‘Estamira’ e a Conferência ‘I am not a monster: schizophrenia’. Nos relatos analisados, os usuários referenciaram o sofrimento psíquico recorrendo ao discurso da Psiquiatria e à utilização de medicamentos, no entanto, alguns se posicionaram contrariamente a esse saber.

Published: April 2023

El monitoreo de calidad de agua para el cultivo de peces es fundamental para incrementar la productividad y competitividad de los piscicultores. La cadena piscícola Caucana se encuentra en un estado de transición entre enfoque de subsistencia hacia enfoque de cadena productiva (Ruano, Silva and Rivera, 2015) y por lo tanto requiere de la introducción con desarrollos tecnológicos que le ayuden a reducir los factores de vulnerabilidad. Partiendo de este enfoque, se diseñó e implementó un prototipo electrónico de monitoreo de  parámetros de calidad de agua, como temperatura, pH, amoniaco y oxígeno disuelto del agua, con el fin de identificar los valores óptimos que garanticen la reducción de las tazas de mortalidad en los cultivos de peces. Las pruebas de campo se realizaron en la granja piscícola “Mamá Lombriz”, ubicada en el municipio de Popayán, en el departamento del Cauca (Colombia). El hardware del prototipo se compone de una sección de acondicionamiento electrónico y un microcontrolador, en el que se realiza el proceso de muestreo, acondicionamiento, adquisición y procesamiento de datos para su despliegue y almacenamiento en computador. La información es enviada por conexión USB a un software con interfaz gráfica para que el usuario visualice las variables y pueda tomar acciones correctivas de acuerdo a cada situación. Con este prototipo se espera contribuir al mejoramiento de las actividades productivas de la cadena piscícola incrementando la competitividad (Joaquí-Daza, 2011) de los agentes productores y reduciendo los porcentajes de mortalidad en los peces cultivados

Evaluación y selección de levadura comercial para el proceso de fermentación alcohólica de hidromiel
Authors: Herrera Johana , León Leinis , Torres Yusleivis , Cano Natalia , Herrera Adriana , Cuenca Martha
Published: April 2023

La fermentación alcohólica ha sido a lo largo de la historia fundamental para el desarrollo de bebidas alcohólicas tales como el vino, la cerveza y el hidromiel. Sus características fisicoquímicas y sensoriales son diferentes no sólo por el origen de las materias primas sino también por el tipo de microorganismo utilizado para llevar el proceso fermentativo. A nivel industrial, la Saccharomyces cerevisiae es la levadura comúnmente utilizada para la producción de bebidas alcohólicas. Sin embargo, en el caso del hidromiel, producto obtenido a partir de miel de abejas diluida y fermentada, comercialmente no hay disponibilidad de levaduras especializadas para este tipo de producto. Por ello, el objetivo de este trabajo fue evaluar la fermentación alcohólica para la obtención del hidromiel utilizando diferentes levaduras disponibles comercialmente. El proceso fermentativo fue realizado de acuerdo con la metodología de proceso estandarizado de hidromiel propuesto en la literatura (Quicazán, Cuenca, & Paz, 2018). De acuerdo con la disponibilidad para su adquisición, se evaluaron tres levaduras diferentes de la especie (Saccharomyces cerevisiae) de las marcas: A (Instant Success), B (Safcider), y C (Safoeno VR 44). Para la selección de la levadura se establecieron tres objetivos: grados Brix y concentración de etanol en porcentaje v/v al final de la fermentación, y una evaluación sensorial afectiva del producto final con 30 jueces no entrenados para evaluar la preferencia. Todas las fermentaciones se llevaron a cabo por duplicado a 25°C durante 408 horas partiendo de un mosto preparado a partir de miel de abejas diluida, con 24°Brix. La levadura B permitió obtener una bebida con 17,5% (v/v) de etanol y una preferencia general de 36,7%. Sin embargo, la bebida obtenida con la levadura C que contenía 10,95% (v/v) de etanol presentó la preferencia más alta por parte de los potenciales consumidores. Por lo tanto, teniendo en cuenta no sólo el contenido de etanol sino la preferencia por consumidores potenciales, se seleccionó la levadura C con el fin de desarrollar futuros estudios tendientes a abordar la producción de hidromiel enfocada al consumidor local colombiano.
A prediction model for the efficacy of transvaginal repair in patients with cesarean scar diverticulum: An evidence-based proposal for patient selection
Authors: Wang Xipeng , Zhou Xingchen , Gao Zhenyan , Chen Huihui , Xipeng Wang , Zhang Jun , Jia Yiyu
Published: April 2023

Objective: To establish a prediction model to help the doctor
determine which patients are more suitable for transvaginal repair based
on the prediction model. Design:All enrolled patients underwent
CSD repair performed by a single team. All women in this study had a
follow-up clinic visit at 6 months to record their menstruation and
measure multiple parameters of the CSD by MRI.
Setting:Retrospective study Sample: This study
included 1015 women who underwent transvaginal repair of cesarean scar
diverticulum (CSD) at Xinhua Hospital and Shanghai First Maternity &
Infant Hospital between June 2014 and May 2021. Main outcome
measures: CSD patients are categorized as having optimal healing when
the menstruation duration is no more than 7 days and the thickness of
residual myometrium（TRM） is no less than 5.39 mm after vaginal repair.
The final nomogram is constructed to predict surgical outcomes based on
pre- and postoperative variables. Results: The key factors
determining optimal healing are the timing of cesarean section;
menstrual cycle; CSD length, width, depth, and the myometrial layer
thickness of the lower uterine segment. With the prediction model,
scores are given to each parameter according to the statistics. Total
scores range from 0 to 25 points with a cutoff point of 16.5. Predicted
that transvaginal repair achieves optimal healing when a score greater
than 16.5 points. Uterine position and preoperative TRM are the key
factors affecting postoperative TRM. The width of the CSD and the
thickness of the lower uterine segment are the key factors affecting
postmenstrual abnormal uterine bleeding (P<0.01).
Conclusions: We establish a prediction model system for the
first time that may predict the repair effect of CSD and can potentially
be useful in future clinical trials to determine which patients should
be repaired or other treatment options.

GETS : Sentence Scoring Scheme in Graph-based Extractive Text Summarization for Text Mining Applications
Authors: Bhattacharya Pronaya , Verma Jai Prakash , Bhargav Shir , Bhavsar Madhuri
Published: April 2023

Recently, there is an exponential influx of textual data in big data
applications, which necessitates the requirement of text mining tools
for analysis of data. In Text Mining applications (TM), Text
Summarization (TS) has emerged as an emergent field in Natural Language
Processing (NLP). Mostly, in TS, abstractive approaches are presented
which build complex models, and thus, a shift is envisioned towards
graph-based extractive text summarization models. Such models allow
review and feedback analysis of a service or product, and have the
benefits of being less complex, flexible, and require low computational
resources. This makes them an effective fit for modern text mining based
big data and Internet-of-Things (IoT) applications. Thus, in the
proposed work, we present a scheme, GETS, which exploits a
graph-based model to establish relations between words and sentences
based on statistical operations. In the scheme, a post processing phase
is presented which uses sentence clustering based on graph preparation.
To make the scheme scalable fit for real world applications, we use the
Apache Spark environment for parallel execution of graph-based
operations. In experimental setup, the Recall-oriented Understudying
Gisting Evaluation (ROUGE) parameters is used to evaluate the proposed
graph based model with a comparative analysis with ROUGE 1,2,L measures.
Comparative analysis is done based on clustered and non-clustered
approaches. The obtained results renders the scheme effective as a
backend of Artificial Intelligence (AI) models in crowdsourcing
applications and decision-analytics models.
Revealing the drivers of parasite diversity: territorial and biodiverse hosts raise haemosporidian regional diversity worldwide
Authors: Dutra Daniela de Angeli
Published: April 2023

Biodiversity varies across the world and is influenced by multiple
factors, such as environmental stability and past historical events
(e.g., Panama Isthmus). At same time, organisms with unique
life-histories (e.g., parasites) are subject to unique selection
pressures that structure their diversity patterns. Parasites represent
one the most successful life-strategies, impacting directly and
indirectly the ecosystem by cascading effects on host fitness and
survival. Here, I focused on a highly diverse, prevalent, and
cosmopolitan group of parasites (avian haemosporidians) to investigate
the main drivers of regional parasite diversity on a global scale. To do
so, I compiled data from four global datasets on (i) avian
haemosporidian (malaria and malaria-like) parasites, (ii) bird species
richness, (iii) avian functional traits, and (iv) climate data. Then,
using generalized mixed models, I evaluated potential drivers of
haemosporidian diversity. I found that haemosporidian diversity is
driven by both host regional diversity and functional traits, and by
environmental conditions. In other words, parasite diversity increased
with increasing host richness and higher numbers of resident and
territorial birds. Further, greater temperature seasonality was also
positively correlated with parasite diversity. Hence, regions harboring
the greatest resident/territorial avian diversity (e.g., neotropics)
and/or higher temperature seasonality (e.g., North America) generally
harbor the highest diversity of haemosporidian parasites. Overall, I
demonstrated that haemosporidian parasite diversity is intrinsically
associated with their hosts’ diversity and functional traits.
Multi-feature based Function Embedding Network for Binary Code Similarity
Authors: LI XIANGYU , WU GUOHAO , GUO ZIHUI , LIANG HONGLIANG
Published: April 2023

Binary similarity detection determines whether two given binary code
snippets are similar or not, usually on function granularity. This task
is challenging due to different compilation optimizations and CPU
architectures. Recently, deep-learning methods have made great
achievements in this field, although most of them use artificially
selected features or ignore some important semantic information like
code literals or function signatures during feature processing. In
addition, random samples and pair loss function are used in similarity
training, which only covers limited similarity relations between
functions. In this paper, a new framework MFEN-Sim is proposed to detect
similar binary functions. The framework contains three stages: feature
extraction and normalization, mutli-feature based function feature
embedding network (MFEN) and similarity learning network. Multiple
features including assembly instructions, CFG structures and function
code literals are extracted from binary functions. Then these features
are fed into MFEN composed of three modules: function semantic and
structure embedding module, function signature prediction module, and
function code literal embedding module. The three modules generate
embeddings representing the function semantic and structural features,
the function signature prediction features and the function code literal
features. Finally, MFEN-Sim utilizes a similarity training network based
on contrastive learning to make MFEN recognize more similarity relations
between functions. MFEN-Sim is evaluated on 281,601 functions in 144
binaries and 17 CVEs in real-world software. Experimental results show
that our work outperforms state-of-the-art systems ( i.e.,
Gemini, FIT and SAFE) by 7.1%, 9.9% and 8.2% on AUC metric in
cross-architecture, optimization-level similarity detection, and
achieves higher recall than baselines in searching vulnerabilities in
real-world applications.
SMS Spam Detection System Based on Deep Learning Architectures in Turkish and English Messages
Authors: Albayrak Zafer , Altunay Hakan Can
Published: April 2023

SMS still continues its existence despite the emergence of
different messaging services. It takes a part in our lives as a
communication service to date. Companies use SMS for advertisement
purposes due to the fact that e-mail filtering systems have rooted,
short message systems are being undersold by the operators, and spam
detection and blocking systems used for short messages are ineffective.
Consequently, SMS has attracted the attention of those who send spam to
mobile phone users. This article presents the proposal of a hybrid model
with the aim of detecting SMS spam messages. This detection model uses
GRU and CNN as two deep learning methods. The design for this model was
laid out by using two different datasets containing combined text
messages written in the Turkish and English languages. The testing
process was performed on the dataset through benchmarking as well as
other machine learning algorithms. It was revealed in the study that the
hybrid CNN+GRU approach attained an accuracy of 99.12% by demonstrating
a better performance compared to the other algorithms.

Published: April 2023

Chikungunya virus (CHIKV) is an arbovirus ( Togaviridae family,
Alphavirus genus), first identified in 1953 in Tanzania. In 2005,
CHIKV emerged in India, and later caused outbreaks in Southeast Asia,
Oceania and the Americas. Some Clinical signs are associated with CHIKV
infection include fever and/or concomitant arthralgia, neurological
manifestations and death. However, in infections caused by other
arboviruses, such as the Dengue virus and West Nile virus, its often
observed changes in liver enzymes. This study aims to evaluate the
profile of the biochemical markers for kidney and liver injury patients
infected with CHIKV in acute phase of infection. We found a significant
elevation on the levels of creatinine in CHIKV-infected people, possibly
associated with myalgia and indicative of muscle damage. The novelty was
the elevated levels of creatinine found during a long period.
Effect of Building Direction on High Cycle Fatigue Properties and Life Prediction of SLM Al-Si Alloy
Authors: Li Wei , Zhang Yucheng , Li Cheng , Sun Chuanwen , Wang Shuowen
Published: April 2023

The influence of building direction (0°, 45° and 90°) on high cycle
fatigue properties of a selective laser melted Al-Si alloy was
investigated through uniaxial loading fatigue tests under stress ratio
of 0 in combination with multi-dimensional imaging and electron
backscattered diffraction analysis. Surface/subsurface failures were
induced by single irregular lack of fusion defect originated from
un-melt powder or inhomogeneous microstructure. Fatigue properties
decreased as building angle arose, attributing to the size difference of
original defect dominating crack nucleation, and the distribution
difference of melting pool boundaries deflecting crack growth. According
to the stress intensity factor evaluation, the threshold value of long
crack growth and the transition size of crack growth exhibited
decreasing tendency as building angle increased. Considering the
influence of building direction on defect size distribution, a fatigue
index parameter controlled crack nucleation life prediction model was
established and the prediction result was satisfactory for safety
design.

The Behavioral Effects of Social Distance and Residual Claim Distribution on Budget Reporting in Hierarchical Organizations
Authors: Kuang Xi , Majerczyk Michael , Yang Di
Published: April 2023

We experimentally investigate how subordinates’ budget reporting in hierarchical organizations is influenced by social distance between subordinates and their direct manager. Although prior research promotes reducing this social distance to improve cooperation and efficiency, we contend that reduced social distance can differentially influence budget reporting, conditional on the manager’s stake in the residual claim. As predicted, we find through two studies that the effect of reduced social distance changes from increasing subordinates’ honesty to decreasing subordinates’ honesty as the manager’s stake in the residual claim decreases. We also find that subordinates’ concern for the manager’s economic well-being and concern about the manager’s impression of their reporting behavior mediate these results. The implications of our findings for management accounting theory and practice are discussed.

Diet modulates the development of insulin resistance during aging. This includes tissue-specific alterations in insulin signaling and mitochondrial function, which ultimately affect glucose homeostasis. Exercise stimulates glucose clearance, mitochondrial lipid oxidation and enhances insulin sensitivity. It is not well known how exercise interacts with age and diet in the development of insulin resistance. To investigate this, oral glucose tolerance tests (OGTT) with a tracer were conducted in mice ranging from 4 to 21 months of age, fed a low- (LFD) or high-fat diet (HFD), with or without life-long voluntary access to a running wheel (RW). We developed a computational model to derive glucose fluxes, which were commensurate with independent values from steady-state tracer infusions. Both insulin sensitivity indices derived for peripheral tissues and liver (IS-P and IS-L, respectively) were steeply decreased by aging and a HFD. This preceded the age-dependent decline in the mitochondrial capacity to oxidize lipids. In LFD young animals, RW access enhanced the IS-P concomitantly with the muscle β- oxidation capacity. Surprisingly, RW access completely prevented the age-dependent IS-L decrease, but only in LFD animals. This study indicates, therefore, that endurance exercise can improve the age-dependent decline in organ-specific IS mostly in the context of a healthy diet.

Corrosion Fatigue of Copper in Aqueous Media

Published: April 2023

The failure of the cooling systems of engines and propellers of the ship poses the serious hazard to passengers and crew. Damage to these units is often caused by corrosion, with localized corrosion being the most dangerous. In the case under consideration, when the metal is simultaneously affected by a corrosive environment and alternating mechanical loads, conditions arise for the behaviour (occurrence) of corrosion fatigue. The prospects of cathodic electrochemical protection of these units are considered in the paper. Since the cooling systems and propellers are made of copper alloys, the effect was studied concerning the potential and composition of the solution on the corrosion of the main component of the structural material — copper. Copper samples with a smooth mechanical pressure concentrator cantilevered in a fluoroplastic electrochemical cell were tested. Alternating bending loads were applied to them, and the number of load cycles before the destruction of the sample (durability) was determined. The experiments were carried out in deaerated solutions of the surfactantly inactive electrolyte NaF, as well as fluoride solutions with additives of surfactants and organic surfactants - benzotriazole. At the same time, an interval of potentials was set, in which the only Faraday process is possible — the reduction of traces of dissolved oxygen. It was found that at potentials less than the zero charge potential, the durability of copper increases significantly. And the introduction of chloride ions and benzotriazole into the solution, on the contrary, leads to a strong decrease in its durability. The potential of zero charge of copper was determined from the measurement data of the differential capacitance of the metal in sodium fluoride solutions with different concentrations of fluoride. The increase in the durability of the metal is explained by the occurrence of hydrogen bonds between the water molecules adsorbed by the hydrogen atoms. This manifests the so-called negative Rebinder effect. For electrochemical protection, the potential range is recommended below the potential of zero charge of the metal, but above the potential of water decomposition. For cooling systems, it is recommended to use deionized water as a coolant.

The history and the current state of the legal regulation of the development, approval and application of the checklists by the federal state control (supervision) bodies are considered on the example of Rostechnadzor checklists. It is shown that in some cases the checklists are useless when conducting control (supervision) activities. The checklists were introduced into the legislation on the state control (supervision) and municipal control relatively recently, but the legal norms associated with them were already changed. During these changes, the field of the checklists application was expanded, and the questions included in them were potentially ceased to be the only questions that need to be answered when the officials of the federal state control (supervision) bodies carry out control (supervisory) activities, including on-site inspections. At the same time some uncertainty remained in the legislation related to the checklists. The following conclusions are made. 1. Legitimate checklists approved by Rostechnadzor and posted on its official website are not currently available and cannot be used during on-site inspections. 2. Forms of the checklists approved by the Orders of Rostechnadzor and posted on its official website should not be used during on-site inspections, since this is not provided for by the legislation, but can be used for self-examination. 3. The ability to not limit the check to the assessment of compliance with the requirements, for which there are questions in the form of a checklist, significantly reduces the importance of the checklists as a tool for formalizing and optimizing checks. 4. From the Federal Law of July 31, 2020, № 248-FZ «On State Control (Supervision) and Municipal Control in the Russian Federation», it is advisable to exclude the provisions on the approval of checklists by the state control (supervision) bodies, and their placement on the official websites of these bodies.

Currently, activated carbon adsorbents are widely used in the world for industrial wastewater treatment from various organic compounds, sorption of heavy metal ions and life-threatening radioactive substances. Carbon adsorbents with hydrophobic properties are mainly modified based on the brown coal, coke, scape, and bark of plants. The methods of manufacturing coal adsorbents based on Angren coal, petroleum coke and asphaltenes are listed. The physicochemical composition and complete thermodynamic properties of the activated carbon adsorbent were studied. It was found that during the heat treatment of mixtures of carbonaceous raw materials, its mass is lost with increasing temperature. At the same time, the adsorption activity of iodine increases with increasing temperature. Depending on the change in temperature of the obtained carbon adsorbent samples, the calculated surface area with respect to iodine is 280.7 m2/g with a weight loss of 0.2 g. The differential heat of adsorption, isotherm, molar entropy and thermokinetics of the benzene and toluene molecules studied in the article are calculated. The adsorption of 4.5 mmol/g of benzene and 3.5 mmol/g of toluene on the activated carbon adsorbent was determined. It is noted that during the adsorption of benzene and toluene by the obtained adsorbent from activated carbon, the differential heat of reaction gradually decreases. When recalculating the isothermal adsorption of benzene and toluene on activated carbon according to the equation of the volumetric theory of micropore saturation, it was obtained that 84.5 % of benzene and 94.2 % of toluene were adsorbed on the pores of the adsorbent.
Quality of Work Life And Medical Teachers’ Commitment: A moderated mediation analysis of fear of COVID-19 and job satisfaction
Authors: Rai Gaurav Deep , Verma Saurabh
Published: April 2023

This study is principally the first to test a moderated mediation model of COVID-19 fear and job satisfaction in the Quality of Work Life (QWL)-commitment relationship of medical teachers during the pandemic. The conceptual model draws its theoretical tenet from spillover and conservation of resources theories.
Cluster sampling was incorporated from four metropolitan cities in India. A mixed-method research design was administered to 378 medical teachers amidst the pandemic. The partial least squares structural equation modeling (PLS-SEM) results indicate a significant positive association between the constructs. Path analyses have highlighted positive associations between QWL, job satisfaction, and affective commitment to medical institutions. Further, a partial mediation effect of job satisfaction in the QWL-commitment relationship is highlighted, adding a new dimension to past studies. Intriguingly, each of the positive associations between QWL, job satisfaction, and commitment was negated and significantly moderated by the fear of COVID-19 experienced by the medical teaching fraternity.
The findings offer practical implications to the stakeholders (Ministry of Health and Family Welfare, Department of Higher Education, Government of India, and State Governments) in enriching the QWL, job satisfaction, and medical teachers’ commitment induced by psychological stress, anxiety, role conflict, post-traumatic stress disorder, and fear of COVID-19 in the global pandemic.

"In order to clearly see the problems arising in the teaching of the Romanian language and to find out the suggestions regarding to the solution, we need to know the opinion of the teachers who teach in elementary classes. This research endeavors to find out how teachers experience the Romanian lessons given in Hungarian classes, how they motivate the children and what suggestions they have for the parents. I interviewed a total of 52 teachers from different counties of the country. More than half of the interviewed teachers declare that they like the Romanian lessons and experience them as a challenge. Most of them devote an hour or more for the preparation of the Romanian lessons. Almost half of the teachers (44,23%) claim that children are not motivated to learn the Romanian language. There are even students who do not speak or do not want to speak at all at the Romanian lessons. Teachers motivate these children through more encouragement, games, pair work, retelling and helpful questions. Most of the teachers think that the reason of the failure may be that there is no suitable environment for practicing the Romanian language, and the parents' attitude towards the Romanian language is not always appropriate either. Although the majority of the parents would wish to be partners in motivating their children to learn the Romanian language, since they do not know Romanian well either, they cannot help their children. The following suggestions are the most common among those addressed to the parents: talk to their children in Romanian at home, find Romanian-speaking friends for their children, watch Romanian fairy tales/cartoons with them and take them to an environment where they have the opportunity to practice the Romanian language. Keywords: teachers who teach in Hungarian classes, children, parents, Romanian lessons, opinion"

Published: April 2023

Using scanning electron microscopy, the surface morphology of a split leather sample was studied under the action of laser radiation from the front and backsides. It has been established that the effect of laser skin resurfacing is achieved in the range of input energies of 40 J and exposure times of 40 sec. It was found that laser exposure from the front and backsides leads to polishing of splits. Skin resurfacing from the front and leather split starts at different input energies from the front side from the split, which is associated with a looser structure of the leather from the split and its lower absorption of radiation.
Tengsl fræða og starfs í kennaramenntun: Sjónarhorn nema

Kennaramenntun hefur víða verið gagnrýnd fyrir skort á samhengi innan námsins og einnig skort á tengslum milli námskeiða í kennaranámi og starfa kennara á vettvangi. Alþjóðlegar rannsóknir á kennaramenntun benda til þess að lykilatriði í árangursríkum undirbúningi fyrir kennarastarfið séu tækifæri til að læra og æfa aðferðir sem byggja á og tengjast raunverulegu starfi kennara í kennslustofu. Því leggja rannsakendur og stefnumótendur um allan heim í síauknum mæli áherslu á að móta aðferðir í kennaramenntun sem brúa bilið milli fræða og starfs. Tilgangur þessarar rannsóknar var að skoða sýn nema á samhengi í grunnskólakennaranámi og tækifæri sem þeir fá til að tengja saman fræði og starf með árangursríkum hætti. Gögnum var safnað með spurningakönnun þar sem upplifun nema af ýmsum þáttum kennaranámsins var skoðuð og svöruðu 178 nemar á lokaári í grunnskólakennaranámi við Háskóla Íslands og Háskólann á Akureyri. Skoðað var hvort munur væri á sýn nema eftir háskólum, hvort þeir væru í launuðu starfsnámi eða hefðbundnu vettvangsnámi og hvort þeir væru í fimm ára samfelldu kennaranámi eða meistaranámi að lokinni bakkalárgráðu af öðru sviði. Niðurstöður gefa vísbendingar um að námið undirbúi kennaranema nokkuð heildstætt undir kennslu að námi loknu en gefa einnig til kynna að rými sé til úrbóta þegar kemur að tengslum fræða og starfs.
From Millennium Development Goals to Sustainable Development Goals: Transforming development communication to sustainability communication
Authors: Kannengießer Sigrid
Published: April 2023

At the highest international political level, the United Nations declared the Sustainable Development Goals (SDGs) in 2015 after having announced (and later not fulfilled) the Millennium Development Goals (MDGs) in 2000. This shift from the MDGs to the SDGs, in which the term development was replaced by the concept of sustainability, also demands a paradigm shift within the research field of development communication and communication for social change which needs to put the focus on sustainability, embracing the concept of sustainability communication as key when analyzing and practicing social change by the use of communication and media. The article unfolds this argument by explaining the political shift from the MDGs to the SDGs and the relevant research fields analyzing these different goals and then sketching the research areas of development communication and communication for social change as well as the one of sustainability communication. In bringing all these areas together, it is argued that the change of the political goals provokes the above mentioned paradigm shift in the research area of development communication. Transforming development communication into sustainability communication also allows to focus the broad term of communication for social change on a specific aim – which is sustainability.

We are pleased to present to you the first of the three issues of Studies in Communication Sciences scheduled for publication in 2023. Beginning in 2022 and on a trial basis, SComS begun to publish three issues per year in response to the increased number of submissions. We are continuing our trial which allows us to offer two issues with Thematic Sections which have been very important to our community of readers. This still leaves us another full issue dedicated exclusively to general submissions. In 2023, SComS will publish two Thematic Sections “Old media persistence. Past continuities” in issue 23-3. The Thematic Section in this issue 23-1 is titled: “Historizing international organizations and their communication – institutions, practices, changes”. We have enjoyed receiving very interesting proposals for Thematic Sections. At this moment, we already have Thematic Sections planned for 2024. If you are thinking of organizing one, please plan ahead and we look forward to receiving your proposal.
On new aspects of Chebyshev polynomials for space-time fractional diffusion process
Authors: Demir Ali , Bayrak Mine Aylin , Bulut Alper , Ozbilge Ebru , Çetinkaya Süleyman
Published: April 2023

Chebyshev collocation scheme and Finite difference method plays central roles for solving fractional differential equations (FDE). Therefore purpose of this paper is to solve fractional mathematical problem of diffusion by Chebyshev collocation method which turns the original problems into the system of fractional ordinary differential and algebraic equations by imposing orthogonality property. This system is solved by implementing Finite difference method. The numerical illustrations confirm that the combination of these two methods allow us to establish one of the best truncated solution in the series form.
