Published: September 2023

The aim of this study is to understand how Jordanian journalists view social media networks as being related to the news industry in Jordan and the extent of their dependence on these networks in producing news. It also explores the opinions of Jordanian journalists on the pros and cons of these networks through the lens of the relationship between these networks and professional journalism. This study uses the qualitative approach by conducting interviews with a number of professional journalists. The findings indicate that Jordanian journalists perceive social networks as an essential and beneficial development. There is optimism among journalists about the relationship between professional journalism and social media. Also, social networks have brought several benefits to professional journalism. The results also show that journalists firmly believe that social networks cannot be considered a substitute for traditional media.

Background and Aim: Trichinellosis is caused by a species of roundworm called Trichinella and is an invasive disease causing severe medical, veterinary, and socioeconomic problems worldwide. More than 100 mammalian species are Trichinella hosts. Among domestic animals, pigs and dogs are prone to trichinellosis. An essential aspect of controlling the spread of infection is to identify the number and level of infections in wild carnivores in the country. However, the number, habitats, and movements of wild animal Trichinella hosts in Kazakhstan have not been reported yet. This study aimed to monitor the wild animal habitat nearby the settlements for tracking the trichinellosis speading among carnivores.

Materials and Methods: Wild carnivorous animals were captured in seven regions of the Republic of Kazakhstan. The carcasses of corsacs, wolves, foxes, wild boars, and badgers were studied. Muscle tissue samples from spontaneously infected wild animals were collected. The digestion method in “GASTROS-2M” was used to isolate Trichinella spp. from animal muscles. The species of the parasite was determined by a polymerase chain reaction for 5S spacer of Trichinella ribosomal DNA with subsequent sequencing by Senger. Statistical analysis methods were performed for average value in Microsoft Excel 2010.

Results: The results of the research showed that among 155 animals wolves (20.4%) and foxes (26.7%) were the most infected with invasive Trichinella larvae. The invasion intensity was 503.6% in foxes and 289.7% in wolves. However, badgers (164%), wild boars (0%), and corsacs (0%) presented lower invasion levels. Using specific primers, larvae samples were identified as Trichinella nativa.

Conclusion: The results of monitoring revealed the spread of trichinosis among wild animals: wolves, foxes, badgers. The Karaganda, Kostanay, Western Kazakhstan, and Akmola regions had the largest distribution of wild animals infected with trichinellosis. In total, 20% of the 155 studied animals were infected. The greatest invasion intensity was typical for wolves, foxes and badgers. It is necessary to monitor the spread of trichinellosis among wild carnivores to control the epidemiological situation and reduce the level of spontaneous infection among animals. Regular monitoring of habitats and carnivores must be conducted within the country and in the border areas.

Keywords: distribution, intensity of infection, trichinellosis, wild carnivores.

A digitalizáció hatása a feldolgozóipari vállalatok üzleti teljesítményére Magyarországon
Authors: Kulcsár Imre Gábor , Nemeslaki András
Published: September 2023

A GDP 24,3%-át Magyarországon az ipari termelés adja, azonban a termelékenység tekintetében az ország az EU-s átlag 70%-ával nem áll előkelő helyen. Ez a tanulmány empirikus adatok elemzésen keresztül megmutatja, hogy a folyamatok digitalizációja hozzásegítheti a vállalatokat magasabb munkatermelékenység eléréséhez. Erre egy új digitalizációt mérő mutatószám bevezetésével, az üzleti folyamatok digitális integráltságának mérésével (Digital Business Process Integration Index, DBII) kerül sor. Ezt a mérőszámot Porter értékláncelmélete és egy kérdőíves kutatás eredményei alapján alakították ki a szerzők. Az eredmények alapján elmondható, hogy az üzleti folyamatok digitalizáltsága és a vállalat munkatermelékenysége között közepesen erős asszociatív kapcsolat áll fenn. További pozitív összefüggés mutatható ki a szervezet IT-képességei és a munkatermelékenység között. Pozitív asszociációs kapcsolat áll fenn a DBII és az üzleti eredmény között is, azonban nem a legmagasabb DBII-vel rendelkező vállalatok átlagos üzleti eredménye a legmagasabb.
Hazai vállalatok ipar 4.0 felkészültségének értékelése : Modelljavaslat és annak esettanulmányokon keresztül történő vizsgálata
Authors: Gelei Andrea , Ternai Katalin , Lengyel Elizabeth
Published: September 2023

Az Ipar 4.0 (I 4.0) alkalmazások gyakran nem hozzák az elvárt eredményeket, melynek okai sokrétűek. Az egyik ok, hogy a rendelkezésre álló, számos érettségi/felkészültségi modell nem képes megfelelő mélységben megragadni az alkalmazás előfeltételeit, így a vállalatok úgy vágnak bele ezekbe, hogy arra valójában még nem felkészültek. A cikk erre a problémára reflektál, amikor a Design Science Research (DSR) módszertanát alkalmazva egy olyan felkészültségi modellt mutat be, mely az I 4.0 alkalmazásokhoz szükséges, alapvető képességek értékelésére fókuszál. Az eddigi tudományos eredményeket hét szakértői interjúval egészítették ki a szerzők, s ezek alapján tesznek javaslatot a modellre. A cikk részletesen bemutatja annak felépítését, ezt követően a javasolt értékelési rendszer nyolc vállalati esetre történő alkalmazásának eredményeit. Ezek tükrében konkrét javaslatokat tudnak tenni a szerzők arra, hol és milyen módon lehet a cégek felkészültségén javítani. A DSR megközelítésének megfelelően, a modellel és az azt támogató kérdőívvel kapcsolatos visszajelzések alapján tudták véglegesíteni értékelési rendszerüket és lezárni a kutatást.
Knowledge exchange and capacity building in deltas: experiences of the Delta Alliance
Authors: van Nieuwaal Kim , Langenberg Victor , Odhengo Peter
Published: September 2023

Deltas are areas where pressures (e.g. climate change, rapid urbanization, water related shocks and stressors) as well as opportunities (e.g. economic growth, delta-city metabolism, sustainable development) collide to an unprecedented extent. The deltas are considered to become the most vital and critical hotspots in the world for sustainable development. Consequently, immediate acceleration in hands-on knowledge partnerships is required for sustainable low-carbon emission and resilient investments in delta areas. The mission of the Delta Alliance is to improve the resilience of the deltas in the world through knowledge sharing and capacity building. In this paper we elaborate on the various roles that the Delta Alliance has played and how this has been of significance for other developing delta regions in the world. Some of the successes and lessons learned are highlighted, with a particular focus on the African deltas. We argue that increasing investments in knowledge sharing and capacity building among - and with - those working in the deltas for creating equitable and trusted partnerships are a necessary condition for an integrated approach to the challenges in the deltas.

Authors: Fontella Joni Márcio Dorneles
Published: September 2023

O presente artigo é resultado da pesquisa de doutorado intitulada “Termos do Turismo em artigos acadêmicos em inglês: um estudo terminológico” (Fontella, 2023). O objetivo principal é apresentar uma parte do termos do Turismo coletados de um corpus composto por mais de 500 artigos científicos da área, juntamente  com uma análise comparativa dos termos de uma das subáreas do Turismo – Comidas e Bebidas. O vocabulário acadêmico (VA) tem sido objeto de estudo em diversas pesquisas nas últimas décadas. As primeiras listas de palavras acadêmicas foram desenvolvidas, de forma manual, nos anos de 1970. Xue e Nation (1984), já com o auxílio de computadores, compilaram listas elaboradas na década anterior e criaram uma lista que foi considerada a principal fonte desse tipo de vocabulário, a University Word List (UWL). No ano 2000, baseando-se em um corpus composto de textos acadêmicos de diversas áreas e disciplinas, Averil Coxhead elaborou a Academic Word List (AWL), a qual passou a ser a referência de vocabulário acadêmico desde então. O VA é composto por diferentes tipos de vocabulários, entre eles o vocabulário fundamental (VF), palavras estritamente acadêmicas e termos. Revisitamos as noções de VF (Biderman, 1996) e de VA (Nation, 2013; Snow; Ucelli, 2009) para que pudéssemos comparar os termos selecionados no corpus com as duas listas, a General Service List (GSL) (West, 1953), referência de VF; e a AWL, referência de VA. A análise dos termos da subárea de Comidas e Bebidas revelou que há maior incidênica de itens lexicais que coincidem com o VF da língua inglesa do que com o VA.

Published: September 2023

Modern cloud networks are a fundamental pillar of data-intensive applications. They provide high-speed transaction (packet) rates and low overhead, enabling, for instance, truly scalable database designs. These networks, however, are fundamentally different from conventional ones. Arguably, the two key discerning technologies are RDMA and programmable network devices. Today, these technologies are not niche technologies anymore and are widely deployed across all major cloud vendors. The question is thus not if but how a new breed of data-intensive applications can benefit from modern networks, given the perceived difficulty in using and programming them. This tutorial addresses these challenges by exposing how the underlying principles changed as the network evolved and by presenting the new system design opportunities they opened. In the process, we also discuss several hard-earned lessons accumulated by making the transition first-hand.
PSFQ: A Blockchain-Based Privacy-Preserving and Verifiable Student Feedback Questionnaire Platform
Authors: Ni Wangze , Chen Pengze , Chen Lei
Published: September 2023

Recently, more and more higher education institutions have been using student feedback questionnaires (SFQ) to evaluate teaching. However, existing SFQ systems have two shortcomings. The first is that the respondent of an SFQ is not anonymous. The second is that the statistical report of SFQs can be manipulated. To tackle these two shortcomings, we develop a novel SFQ system, namely PSFQ. In PSFQ, the respondent of an SFQ is mixed with multiple users by a ring signature. PSFQ uses an advanced ring signature approach to minimize the size of a ring signature when anonymity satisfies the requirements. Thus, the first shortcoming has been overcome. Moreover, all answers are encrypted by homomorphic encryption and stored on the blockchain, enabling users to verify the correctness of the statistical reports. Our demonstration will showcase how PSFQ provides confidential SFQ responses while ensuring the correctness of statistical reports.

Published: September 2023

Time series has been found with various data quality issues, e.g., owing to sensor failure or network transmission errors in the Internet of Things (IoT). It is highly demanded to have an overview of the data quality issues on the millions of time series stored in a database. In this demo, we design and implement TsQuality, a system for measuring the data quality in Apache IoTDB. Four time series data quality measures, completeness, consistency, timeliness, and validity, are implemented as functions in Apache IoTDB or operators in Apache Spark. These data quality measures are also interpreted by navigating dirty points in different granularity. It is also well-integrated with the big data eco-system, connecting to Apache Zeppelin for SQL query, and Apache Superset for an overview of data quality.

Published: September 2023

Approximate Query Processing (AQP) systems produce estimation of query answers using small random samples. It is attractive for the users who are willing to trade accuracy for low query latency. On the other hand, real-world data are often subject to concurrent updates. If the user wants to perform real-time approximate data analysis, the AQP system must support concurrent updates and sampling. Towards that, we recently developed a new concurrent index, AB-tree, to support efficient sampling under updates. In this work, we will demonstrate the feasibility of supporting realtime approximate data analysis in online transaction settings using index-assisted sampling.
KG-Roar: Interactive Datalog-Based Reasoning on Virtual Knowledge Graphs
Authors: Bellomarini Luigi , Benedetti Marco , Gentili Andrea , Magnanimi Davide , Sallinger Emanuel
Published: September 2023

Logic-based Knowledge Graphs (KGs) are gaining momentum in academia and industry thanks to the rise of expressive and efficient languages for Knowledge Representation and Reasoning (KRR). These languages accurately express business rules, through which valuable new knowledge is derived. A versatile and scalable backend reasoner, like Vadalog, a state-of-the-art system for logic-based KGs---based on an extension of Datalog---executes the reasoning.

In this demo, we present KG-Roar, a web-based interactive development and navigation environment for logical KGs. The system lets the user augment an input graph database with intensional definitions of new nodes and edges and turn it into a KG, via the metaphor of reasoning widgets---user-defined or off-the-shelf code snippets that capture business definitions in the Vadalog language.

Then, the user can seamlessly browse the original and the derived nodes and edges within a "Virtual Knowledge Graph", which is reasoned upon and generated interactively at runtime, thanks to the scalability and responsiveness of Vadalog. KG-Roar is domain-independent but domain aware, as exploration controls are contextually generated based on the intensional definitions.

We walk the audience through KG-Roar showcasing the construction of certain business definitions and putting it into action on a real-world financial KG, from our work with the Bank of Italy.
BrewER: Entity Resolution On-Demand
Authors: Zecchini Luca , Simonini Giovanni , Bergamaschi Sonia , Naumann Felix
Published: September 2023

The task of entity resolution (ER) aims to detect multiple records describing the same real-world entity in datasets and to consolidate them into a single consistent record. ER plays a fundamental role in guaranteeing good data quality, e.g., as input for data science pipelines. Yet, the traditional approach to ER requires cleaning the entire data before being able to run consistent queries on it; hence, users struggle to tackle common scenarios with limited time or resources (e.g., when the data changes frequently or the user is only interested in a portion of the dataset for the task).

We previously introduced BrewER, a framework to evaluate SQL SP queries on dirty data while progressively returning results as if they were issued on cleaned data, according to a priority defined by the user. In this demonstration, we show how BrewER can be exploited to ease the burden of ER, allowing data scientists to save a significant amount of resources for their tasks.
Demonstrating ADOPT: Adaptively Optimizing Attribute Orders for Worst-Case Optimal Joins via Reinforcement Learning
Authors: Wang Junxiong , Gray Mitchell , Trummer Immanuel , Kara Ahmet , Olteanu Dan
Published: September 2023

Performance of worst-case optimal join algorithms depends on the order in which the join attributes are processed. It is challenging to identify suitable orders prior to query execution due to the huge search space of possible orders and unreliable execution cost estimates in case of data skew or data correlation.

We demonstrate ADOPT, a novel query engine that integrates adaptive query processing with a worst-case optimal join algorithm. ADOPT divides query execution into episodes, during which different attribute orders are invoked. With runtime feedback on performance of different attribute orders, ADOPT rapidly approaches near-optimal orders. Moreover, ADOPT uses a unique data structure which keeps track of the processed input data to prevent redundant work across different episodes. It selects attribute orders to try via reinforcement learning, balancing the need for exploring new orders with the desire to exploit promising orders. In experiments, ADOPT outperforms baselines, including commercial and open-source systems utilizing worst-case optimal join algorithms, particularly for complex queries that are difficult to optimize.
Generations of Knowledge Graphs: The Crazy Ideas and the Business Impact
Authors: Dong Xin Luna
Published: September 2023

Knowledge Graphs (KGs) have been used to support a wide range of applications, from web search to personal assistant. In this paper, we describe three generations of knowledge graphs:
entity-based KGs
, which have been supporting general search and question answering (
e.g.
, at Google and Bing);
text-rich KGs
, which have been supporting search and recommendations for products, bio-informatics, etc. (
e.g.
, at Amazon and Alibaba); and the emerging integration of KGs and LLMs, which we call
dual neural KGs.
We describe the characteristics of each generation of KGs, the crazy ideas behind the scenes in constructing such KGs, and the techniques developed over time to enable industry impact. In addition, we use KGs as examples to demonstrate a recipe to evolve research ideas from innovations to production practice, and then to the next level of innovations, to advance both science and business.
Allelic variants of CYP2B6 gene expression and its implication on the pathogenesis of malaria among a cohort of outpatients in North-Central Nigeria
Authors: Shittu Olalere , Oniya Mobolanle Oladipo , Olusi Titus Adeniyi
Published: September 2023

Background

Human cytochrome P450 2B6 (CYP2B6) is fortified with the biotransformation of the antimalarial, artemisinin combination therapy (ACT). Owing to emerging reports of Plasmodium species resistance to ACT in other climes, CYP2B6*6 genotype significantly alters ACT metabolism. In North-Central Nigeria, the distribution of the CYP2B6*6 variant is poorly documented. This study investigated the distribution of CYP2B6 c.516G>T variants and its relationship with certain malaria pathogenesis among a cohort of clinical-malaria outpatients in Ilorin, Nigeria.

Methods

A total of 50 symptomatic P. falciparum malaria-positive samples were genotyped for CYP2B6 c.516G>T using restriction fragment length polymorphism and a specific haplotype population was established. The allele frequencies and genotype distributions were analyzed. Haplotypes were clustered using Ward’s method. Correlations determined include defective CYP2B6 versus parasitemia densities and thrombocytopenia, respectively.

Results

Forty-five samples show genotypic ratios and nine CYP2B6 genetic single nucleotide polymorphisms were identified. The following haplotypes (64C>T = *1/*2, 785A>G = *1/*4, and 1459C>T = *1/*5) occurred and *2, *3, and *18 alleles harbor 64C>T, 777C>A, −82T>C, and 499C>G. The codon 64CT, 516GT, and 785AG; −82TC and 777CA; and 499CG, 516GT, and 785AG were identified as *2/*6 heterozygotes. Samples with 516GT and 785GG genotypes occurred with *4/*6 heterozygotes. Mutant trait alleles recorded high parasitemia 72 h post-ACT regimen. Only individuals with CYP2B6*6 alleles had severe malaria and thrombocytopenia.

Conclusion

This report contributes to the growing knowledge of CYP2B6*6 genotype frequency and its relationship with malaria pathogenesis among a Nigerian population.
Comparison between image based and tabular data-based inclusion class categorization
Authors: R. Babu S. , Musi R. , K. Michelic S.
Published: September 2023

Non-metallic inclusions (NMI) have a significant impact on the final properties of steel products. As of today, the scanning electron microscope equipped with energy-dispersive spectroscopy (SEM-EDS) serves as the state of art characterization tool to study NMIs in steel. The automated 2D analysis method with the SEM-EDS allows for a comprehensive analysis of all the inclusions observed within a selected area of the sample. The drawback of this method is the time taken to complete the analysis. Therefore, machine learning methods have been introduced which can potentially replace the usage of EDS for obtaining chemical information of the inclusion by making quick categorizations of the inclusion classes and types. The machine learning methods can be developed by either training it directly with labeled backscattered electron (BSE) images or by tabular data consisting of image features input such as morphology and mean gray value obtained from the BSE images. The current paper compares both these methods using two steel grades. The advantages and the disadvantages have been documented. The paper will also compare the usage of shallow and deep learning methods to classify the steels and discuss the outlook of the existing machine learning methods to efficiently categorize the NMIs in steel.
Dezincification in cast and heat-treated alpha-beta brass samples
Authors: Biezma M. V. , Strobl S. , Linhardt P. , Ball G. , Haubner R.
Published: September 2023

Two α-β brass alloys with varying Zn contents have been studied. The samples received for examination were heat-treated at 500 °C in order to conduct dezincification studies according to EN ISO 6509-1 and to measure the depth of dezincification from metallographic sections.

According to the phase diagram, the α-phase content should increase as a result of heat-treatment at 500 °C. This phenomenon, however, is difficult to observe in the metallographic sections which were prepared from the heattreated samples. When analyzing the depth of dezincification, it was found that reduced dezincification occurred in the heat-treated samples. This is plausible since β brass is attacked by preferential corrosion.

Not only was uniform layer dezincification observed in the brass alloy with the higher Zn content, but also the onset of plug dezincification. This is associated with the original microstructure of the brass which is characterized by a coarse primary grain size. In this alloy, it is clearly observed that larger areas containing alpha brass will impede the process of dezincification.
Robotization of conventional electrolytic process in metallography
Authors: Ambrož O. , Čermák J. , Jozefovič P. , Mikmeková Š.
Published: September 2023

Electrolytic polishing is a finishing method that removes material from a metal or alloy through an anodic dissolution process. Etching can often be performed in the same electrolyte by simply reducing the applied voltage to 10 percent of that required for polishing. Manufacturers of metallographic equipment present their products as automated. Only the electrolysis process itself is automated. After finishing, the sample must be immediately removed manually by the operator and cleaned. This process is critical with regard to the quality of the final sample surface and safety, because hazardous substances are often handled. The robot is placed next to an electrolytic equipment and handles all sample movements and the cleaning process in the ultrasonic bath in this experiment. The samples are made from ER308LSi austenitic stainless steel using 3D printing by Wire Arc Additive Manufacturing (WAAM). The final surface is achieved electrolytically on the commercial equipment. The aim of the experiment is to compare the microstructure, especially with regard to the possibility of distinguishing delta ferrite. The surface is characterized using various microscopic techniques. Robotization can be the key to improving surface quality and safety.
Navigating Countertransference in Inpatient Settings: Optimizing Interventions for Patients with Borderline Personality Disorder and Repeated Acute Hospitalizations
Authors: Lin Deborah , Zona Luke , Seery Erin
Published: September 2023

Over the years, the psychiatric inpatient treatment paradigm has shifted to more brief stays focused on acute stabilization and psychopharmacologic-focused interventions, rather than individual psychotherapeutic engagement. Unfortunately, this has allowed patients with complex interpersonal dynamics, particularly borderline personality disorder, to slip through the cracks of effective treatment. This can contribute to repeated inpatient admissions, where both patients and clinicians feel trapped in a maladaptive, unhelpful cycle. In this article, we examine the evolution of inpatient treatment with de-emphasized psychotherapy practices, review the particular dynamics that patients with borderline personality disorder may evoke within an interdisciplinary treatment team, and provide a framework of clinically based vignettes for scenarios that may arise within inpatient treatment of this patient population. With attention to countertransference patterns and common pitfalls of communication, we offer alternative approaches and conversations with the hopes of improving outcomes and alliances in a new landscape of psychiatric practice.
