La construcción y aplicación de buenas prácticas en la gestión de requisitos de software es importante para obtener productos de alta calidad. En la industria de software se aplican procesos de mejoramiento continuo de prácticas para educción, análisis, especificación y validación de requisitos. Se evidencia que, en el contexto industrial, se hace compleja la aplicación de prácticas que proponen métodos de software por la dificultad para identificar los componentes de la práctica. Es el caso de la práctica Gestión de Requisitos de RUP. La aplicación de esta práctica es compleja porque no se identifican claramente los componentes de la práctica y los mecanismos de aplicación, seguimiento y evaluación. En este artículo se aplica el Modelo para la Definición de Prácticas en Ingeniería de Software a la práctica Gestión de Requisitos de RUP. Este proceso que busca identificar y definir los elementos esenciales para facilitar la aplicación, seguimiento y evaluación de prácticas se denomina esencialización. De esta manera a partir de una práctica existente se obtiene una práctica bien formada y nombrada que facilita su aplicación, seguimiento y evaluación en contextos reales. Una práctica esencializada facilita a los practicantes entender, aplicar y evaluar la práctica ya que define una estructura adecuada con elementos bien definidos. También aporta en el seguimiento a la salud y el progreso del esfuerzo de Ingeniería de Software mediante el uso del núcleo del estándar Essence.
Repetitive negative thinking about suicide: Associations with lifetime suicide attempts
Authors: Teismann Tobias , Forkmann Thomas , Michalak Johannes , Brailovskaia Julia
Published: September 2021

Background

Repetitive negative thinking has been identified as an important predictor of suicide ideation and suicidal behavior. Yet, only few studies have investigated the effect of suicide-specific rumination, i.e., repetitive thinking about death and/or suicide on suicide attempt history. On this background, the present study investigated, whether suicide-specific rumination differentiates between suicide attempters and suicide ideators, is predictive of suicide attempt history and mediates the association between suicide ideation and suicide attempts.

Method

A total of 257 participants with a history of suicide ideation (55.6% female; Age M = 30.56, Age SD = 11.23, range: 18–73 years) completed online measures on suicidality, general and suicide-specific rumination.

Results

Suicide-specific rumination differentiated suicide attempters from suicide ideators, predicted suicide attempt status (above age, gender, suicide ideation, general rumination) and fully mediated the association between suicide ideation and lifetime suicide attempts.

Conclusion

Overall, though limited by the use of a non-clinical sample and a cross-sectional study design, the present results suggest that suicide-specific rumination might be a factor of central relevance in understanding transitions to suicidal behavior.
An Improved Pheromone-Based Kohonen Self- Organising Map in Clustering and Visualising Balanced and Imbalanced Datasets
Authors: Ahmad Azlin , Yusof Rubiyah , Akmar Zulkifli Nor Saradatul , Ismail Mohd Najib
Published: September 2021

The data distribution issue remains an unsolved clustering problem in data mining, especially in dealing with imbalanced datasets. The Kohonen Self-Organising Map (KSOM) is one of the well-known clustering algorithms that can solve various problems without a pre- defined number of clusters. However, similar to other clustering algorithms, this algorithm requires sufficient data for its unsupervised learning process. The inadequate amount of class label data in a dataset significantly affects the clustering learning process, leading to inefficient and unreliable results. Numerous research have been conducted by hybridising and optimising the KSOM algorithm with various optimisation techniques. Unfortunately, the problems are still unsolved, especially separation boundary and overlapping clusters. Therefore, this research proposed an improved pheromonebased PKSOM algorithm known as iPKSOM to solve the mentioned problem. Six different datasets, i.e. Iris, Seed, Glass, Titanic, WDBC, and Tropical Wood datasets were chosen to investigate the effectiveness of the iPKSOM algorithm. All datasets were observed and compared with the original KSOM results. This modification significantly impacted the clustering process by improving and refining the scatteredness of clustering data and reducing overlapping clusters. Therefore, this proposed algorithm can be implemented in clustering other complex datasets, such as high dimensional and streaming data.
The problem of hypersensitivity to vitamin preparations
Authors: Zaikov S.V. , Gumeniuk G.L. , Veselovsky L.V.
Published: September 2021

ABSTRACT. The problem of the development of adverse reactions as a result of the use of diagnostic and medicinal products (drugs) is becoming increasingly important. Patients more often report reactions to local anesthetics (43.2 % of cases), antibiotics (18.8 %), nonsteroidal anti-inflammatory drugs (9.7 %), other drugs (28.4 %), B vitamins (4-5 %). It is important to understand that hypersensitivity (HS) to vitamin preparations (VP) is very common, according to patients, but not so often confirmed by their in-depth allergy examination. Basic data on HS before the VP were obtained in the 80-90s of the 20th century, but since then the situation has changed radically. The frequency of HS on these drugs is based on medical history when patients use multicomponent VP for oral administration, allergens in which may be other components (shell tablets and capsules, metal salts, flavors, sweeteners, dyes, preservatives). The causative allergens in the injectable forms of VP can also be auxiliary ingredients of the drug, in particular lidocaine and benzyl alcohol. There are only a few scientific publications with the appropriate evidence base for HS to individual VP, more often B vitamins. The clinical picture of HS reactions to VP is diverse (systemic, cutaneous, respiratory, rarely other visceral manifestations). They can develop both immediately and in a delayed type. Part of the VP (B vitamins, vitamin K) can cause the development of anaphylaxis with fatal consequences. VP, as a rule, do not belong to vital drugs therefore it is possible for this reason till now in real clinical practice insufficiently developed methods of allergodiagnostics both in vivo (skin, provocative tests), and in vitro (laboratory tests) among patients with suspicion for the development of HS to VP. It is not possible to perform allergy diagnostics in persons who have taken complex VP, so there is a problem of hyperdiagnosis of drug allergy to them. Therefore, the problem of determining the true allergic reaction in patients who report the development of a history of HS to VP remains relevant. As a rule, after the development of any adverse reaction during the reception of VP on the patient hangs the label “allergy to vitamins” for life without further allergy examination. That is why the problem of HS to VP needs further study.

Paul Gilroy’s The Black Atlantic Quarter a Century Later: Cultural Implications of African Diaspora’s Revision of Modernity
Authors: Hamdoune Lahoussine
Published: September 2021

In his seminal book The Black Atlantic: Modernity and Double Consciousness (1993) Paul Gilroy traces an account of the Black diaspora as a cosmopolitan, historical and cultural Atlantic phenomenon that challenges and corrects Modern construction of ‘culture,’ ‘nation,’ ‘history,’ and ultimately ‘identity.’ Although the book was conceived quarter a century ago, it still continues to influence Black Studies, Migration Studies, Postcolonial Studies, and Diaspora Studies. The present paper intends to shed light and reflect on the two most influential aspects of Gilroy’s book today. One such aspect is Gilroy’s exploration of Black Atlantic histories of (criss)-crossing, migration, interconnection, travel, and exile-- together with the form, content, and performance of diasporic expressive forms-- to revisit the tradition of Modernity and Enlightenment rationality. The other aspect, following from the first, is that while interrogating “national,” “nationalistic,” and “ethnically absolutist paradigms” such as “Englishness,” “Africanism” and “tradition,” he highlights cultural hybridity, transnationality, and memory. By so doing he subverts modernity’s racialized monolithic definition of ‘culture’ and ‘nation (state)’ along with its construction and association with teleological historiography.
Attitudes of EFL College Students of the University of Bisha towards eLearning
Authors: Almaqtri Mahmoud
Published: September 2021

This study aimed to find out the attitudes of the EFL College students of the University of Bisha, Saudi Arabia, towards eLearning after they have studied via this mode for almost two semesters. The study tried to answer four questions related to the participants' preferences of learning mode, the reasons for their preference, the problems with eLearning, and gender differences. Three null hypotheses related to the first three questions referred to above were postulated regarding gender differences if any. The study was mainly quantitative, in which data were collected by means of an online questionnaire administered to 148 EFL students (males and females) who were selected from the target population purposively. The SPSS program (version 20.0) was used to analyze the obtained data. We have found that the majority of participants had positive attitudes to eLearning, and they preferred it to the face-to-face classroom-based mode. Among the reasons they offered for their preference eLearning were their claims that they learned better than with face-to-face mode. In addition to flexibility, this mode saved time, cost and effort, since the students took activities and assessments at home, not at college. All three given hypotheses were accepted in that no gender difference was found.

Authors: Lawal Adekunle
Published: September 2021

Language differences between parents and teachers, if not carefully managed, can cause miscommunication or communication gaps that could hinder both the school’s and students’ progress. This paper explores various ways of translating real-time conversations between teachers and parents who speak a different language. Fourteen K-12 teachers in the United States were surveyed and nine were interviewed to determine how English-speaking teachers can communicate effectively with non-English speaking parents. The findings from the study suggest Microsoft Translator technology for speech translation for conversations to break the language barrier, bridge communication gaps and promote effective bi/multilingual parent-teacher conferences.
Emotional Analysis of G. M. Hopkins’ Spring and Fall
Authors: Quadri Kahkasha Moin , Ahmed Haseeb , Abdul Wahab Mohammed Osman
Published: September 2021

This article critically focuses on the emotions created in the poetry of Gerard Manley Hopkins. It explores the various features responsible for creating feelings in poetry. Among them are word choice, sound choice and imagery. Moreover, it delves into the poem to anayse how devices such as alliteration, simile, metaphor, diction, and symbolism play a vital role. Appropriate implementation of these features create strong emotions in poetry. In most of his poems, Hopkins employed coinage words. In “Spring and Fall”, he doubly used coinage words in a single – line. In the second line of the poem, he coined ‘Goldengroove’ and ‘unleaving’ and in the eighth line ‘wanwood’ and ‘leafmeal’. The word ‘Goldengroove’ is not used for a place in reality yet, and it is a place that represents autumn’s beauty. ‘Golden groove also refers to the ‘Garden of Paradise’. It indicates the four seasons of the year and the chronological phases of human life too. The words ‘golden’ and ‘groove’   are combined to form a single word. The word ‘unleaving’ encapsulates the noun ‘leaf’ employed as a verb possessing a negative prefix ‘un’, which means ‘leaving leaves’. The coinage word ‘unleaving ' is an Anglo-Saxon and comes in the category of pun. Another word, 'wanwood', is also a compound word. ‘Wanwood’ explains the pale condition of trees that have shed their leaves, so they seem to become ‘wan’ or pale.  Initially, the word ‘leafmeal’ appears to be ambiguous, yet this ambiguity is expelled immediately.’Leafmeal’ refers to the phrase ‘leaf by leaf’. The two words ‘wanwood’ and ‘leafmeal’ are originated from Anglo- Saxon ring.  Hopkins entitled the poem” Spring and Fall”, which itself enhances strong emotion. The rhyme scheme's alteration in this innovative poem, “Spring and Fall”, exhibits the speaker's feelings.

INFOGRAFIS PENCEGAHAN COVID 19 MELALUI EKSPLORASI DOKUMENTASI VIDEO PROJECTION MAPPING
Authors: Atmaja Nur Rahmat Ardi Candra Dwi , Johan Ies Wahyudi  , Damar Tri Afrianto
Published: September 2021

The process of changing the initial shape of a facade into a new shape resulting in an optical illusion is an activity called Video Mapping. These objects will visually change from their usual form into a new form that is different and very fantastic. Projection mapping is a medium that can provide the audience with experience to feel three-dimensional effects in two-dimensional fields, or it can also be called immersive media. With the display of a projection mapping on a flat plane, it is possible to reach a wider segment of the material and content regarding government policies related to the Covid-19 preventive health protocol which can be displayed through projection video mapping media. Planning to create work for the Video Projection Mapping Documentation is none other than the departure from anxiety about the presence of conventional media and social media which report simply and monotonously related to government policies related to the prevention of Covid-19 and its health protocols. This is what causes people to just casually respond to the infographic because the content and visualization lack persuasive, dramatic and creative power. Because of this, a method of art creation is formulated in this artistic research, namely how to create infographics that emphasize new media as an alternative media for socializing government policies related to Covid-19 through the creation of the work Documentation Video Projection Mapping as an alternative media for the socialization of Covid-19 prevention.

Angels of Denial
Authors: Longazel Jamie
Published: September 2021

This paper critically analyzes a June 2018 Trump administration press conference, carried out in response to public outcry over U.S. policies designed to separate migrant children from their parents. The press conference featured a large group of so-called “angel parents” – the parents of children who were killed by undocumented immigrants – who argued that because they are permanently separated from their children, they have it worse than parents who had their children taken away by the U.S. government. Despite the speakers being relatively diverse, qualitative analysis of their speeches reveals a rhetoric that coincides with the ideology of white injury (Cacho, 2000). I account for this using the concept of racial transposition (HoSang & Lowndes, 2020), which suggests that such multiculturalism actually helps right-wing movements create a façade of racial innocence as they further deny state violence, criminalize migrants, and justify tough-on-migration policies.

The spread of COVID-19 has caused a high demand for online learning or self-learning at home. We focus on evaluating which media is most suitable for self-learning for the third graders. For effective assessment of children's learning, the study adopted AEIOU: Awareness; Enjoyment; Interest; Opinion formation; and Understanding as the evaluation framework. In this research, three types of media were implemented: animation, educational video, and science comics. Total 145 third graders were divided into three groups: animation group, educational video group, and science comics group, to learn the concept of heat transfer through one kind of media respectively. The results revealed that students had positive feedback on the three dimensions of Awareness, Enjoyment, and Interest. And all three media improved students' understanding of heat transfer without a difference. While in the dimension of Opinion formation, the students had less life experience and pre-knowledge, their performances were relatively low. In summary, the three types of media showed the effectiveness of self-learning for the third graders. Especially the animations proved to be the most suitable for the third-grade children to conduct self-learning. Keywords: science communication, AEIOU, heat transfer, Media

The National Defense University (NDU) trains officers to develop their academic and professional skills. To accomplish this, the university offers two mandatory courses on methodological training for military technology students for master level education. The first course was theoretically oriented, and the second course was practically oriented. These both master-level methodology courses emphasize practice oriented mathematical skills, which officers use in their operative decision-making and statistical analysis. This study focuses on student-centered learning methodologies linked to teachers’ observations from current and previous course implementations. Results in this study described the outcome from the first run of the revised curriculum. We collected data from students’ course reports and the university’s standard student evaluation of teaching (SET). According to the SET, the course 2 which was practically oriented course, where groups worked on more significant projects gained higher value among students. In conclusion, we recommend that teachers continue using student-centered learning methodologies to technical students as much as possible. Theoretically underscored courses should also contain more practical examples. Keywords: distance education, flipped learning, learning by doing, research methodology, student-centered learning

Examining students' inclinations to use algorithms and rules to solve a task was a fruitful area of research in chemical education in the last four decades. This research aimed to examine whether students read the task request carefully, considering its meaningfulness, or they approach it mechanically, applying a set of algorithms by default. The research sample consisted of students majoring in chemistry teaching at the University of Novi Sad, Faculty of Sciences who were in their final year of bachelor studies. The study was conducted during two academic years. The main instrument consisted of five quantitative problems, and each of the problems contained deceptive information that made the calculation nonsensical. The results revealed that most students applied an algorithmic approach without paying attention to the meaningfulness of the task requirements. Additionally, it has been shown that students rely heavily on memorizing formulas without a proper understanding of underlying concepts.

INCREASED STUDENT PERFORMANCE ON PHYSICS CONCEPT INVENTORY TEST AFTER STUDENT-CENTRED APPROACH IN UNIVERSITIES OF LATVIA

Education research has repeatedly shown that active learning in physics is pedagogically more efficient than traditional lecture courses. Widespread application of the active learning is slowed down by the lack of data on the performance of the active learning in widely varying circumstances of different educational systems. We measured the level of understanding of basic physics concepts using Force Concept inventory for students who enrol at different universities in Latvia in calculus-based and non-calculus-based groups and compared the student performance to the pre-test results elsewhere in the world. We measured the growth of concept inventory test results and studied the dependence of the growth on the teaching approach used by university lecturers. About 450 undergraduate students from 12 groups of science and engineering courses taught by 8 lecturers were involved in the study at three universities in Latvia. The Force Concept Inventory multiple-choice test was translated to Latvian and used for pre-/post-tests. The pre-test results showed that the maximum of the distribution of correct answers for non-calculus groups is around 20%, which is the value obtained by the random guessing of test answers, whereas the pre-test results of calculus-based groups was about 50% of correct answers. The test score after taking post-test confirmed that the growth of students’ tests results is closely related to the teaching approach chosen by lecturer, showing that in order to provide physics graduates with a good conceptual understanding of physics, student centred teaching approach was crucial. The use of concept inventories in undergraduate physics education to measure the progress of learning appears to be particularly important in the current situation with a small number of students in physics and a critically small number of future physics teachers, when efficiency of teaching is of crucial importance.

Published: September 2021

The Lawson classroom test of scientific reasoning is a quite popular and widely used tool that measures the level and development of the student's scientific reasoning skills. In this contribution, the results of this test for the N=446 students of the Faculty of Science Palacký University Olomouc from the years 2018–2020 at the beginning of their study were analysed. Calculation of the standard characteristics of the test items (difficulty index, discrimination index and point biserial coefficient) confirms that the test meets the required criteria for the included questions and its overall consistency. Performing the Mann-Whitney rank test with a standard significance level α = .05, the statistically significant difference between males and females was found, on the other hand, no statistically significant difference between the students preparing for their prospective teacher careers and those with technical specializations in chemistry or physics was identified. This contradicts a common belief that students choosing teacher preparation programmes are generally worse in scientific performance and technical subjects. The results also show that about a quoter of the students come to university with a low level of their scientific reasoning skills which should be therefore supported and further developed in lecturing and teaching.

Although cell-free DNA (cfDNA) tests have emerged as a potential non-invasive alternative to bone marrow biopsies for monitoring clonal hematopoiesis in hematologic diseases, whether commercial cfDNA assays can be implemented for the detection and quantification of de novo clonal hematopoiesis in place of blood cells is uncertain. In this study, peripheral plasma cfDNA samples available from patients with aplastic anemia (n=25) or myelodysplastic syndromes (n=27) and a healthy cohort (n=107) were screened for somatic variants in genes related to hematologic malignancies using a Clinical Laboratory Improvement Amendments-certified panel. Results were further compared to DNA sequencing of matched blood cells. In reported results, 85% of healthy subjects, 36% of patients with aplastic anemia and 74% of patients with myelodysplastic syndromes were found to have somatic cfDNA variants, most frequently in DNMT3A, TET2, ASXL1 and SF3B1. However, concordance between cfDNA and blood cell findings was poor for the detection of clonal hematopoiesis when the allele frequency of the variants was <10%, which was mostly observed in the healthy and aplastic anemia cohorts but not in patients with myelodysplastic syndromes. After filtering data for potential artifacts due to low variant allele frequency and sequencing depth, the frequency of clonal hematopoiesis in cfDNA from healthy individuals and patients with aplastic anemia decreased to 52% and 20%, respectively. cfDNA and matched blood cells were not interchangeable for tracking changes in allele burdens as their agreement by Bland-Altman analysis was poor. A commercial cfDNA assay had good performance for de novo detection of clonal hematopoiesis in myelodysplastic syndromes, but showed no advantage over blood cells in diseases with low allele burdens or in healthy individuals.
