GRAPH DATA ANALYSIS

Suppose we have a graph G(V,E) where V is the set of vertices and E is the set of edges. Often, the graph is given by the list of its vertices 1, . , n, and the list of edges (i, j), i, j ∈ {1, . , n}. The list of edges, sorted according to the tail vertices of the edges is easily recasted into the adjacency list. Another way to define a graph is to provide its n×n adjacency matrix A = (Aij) where Aij = 1 if there is an edge from i to j and Aij = 0 otherwise. These ways of defining a graph is suitable for both, directed and undirected graphs, and can easily be extended to a weighted graph by adding weights to the list of edges. Given a graph, the first natural question is whether it is connected or not. If, not, what are its connected components?

Received on: 08/28/2020 Approved on: 11/09/2020 ABSTRACT | Objective: to identify the nursing concepts and care related to Kennedy's Terminal Injury available in the literature. Method: This is an integrative review that used the BVS and CAPES Journals Portal Database, using the MEDLINE, LILACS, BDENF and SciELO. Studies that evaluated Kennedy's Terminal Injury and nursing care were considered. Results: A total of 05 publications in the form of texts and full abstracts were included, 04 studies and 01 editorial. The studies are in a foreign language (English and Spanish), thus reinforcing the alert to the need of the national scientific community. The data were categorized, being grouped into two categories: Kennedy's Terminal Ulcer and its peculiarities and the strategies of Nursing actions at the end of life. Conclusion: There is still a shortage in scientific studies mainly by the national scientific community, in particular nurses demonstrating the lack of knowledge produced related to caring for patients affected by Kennedy's Terminal Injury.
The Effect of Programming Classes with Tangible Scratch Blocks on the Programming Interest of 6th Grade Elementary School Students

In this paper, we introduce an original, classroom-based approach for teaching Scratch programming to 6 th grade elementary school students. Scratch is a programming language that involves assembling icon-based command blocks. It was designed to avoid the complex syntax errors seen in other programming languages, making it especially accessible for younger learners. While Scratch does provide a visual programming environment in which potentially just about anyone can learn to read and write programming code, there can still be a reduced overall interest in learning programming, because younger learners in particular can find it difficult to intuitively understand or be stimulated by abstract concepts of programming such as sequences, conditions, and repetition, which are present in Scratch. Our research involves the development of a tangible, electronic block system that allows students to manipulate physical objects with their hands to perform programming tasks. The system consists of a Scratch simulator and physical, Scratch electronic blocks embodying Scratch user interface shapes. We devised and delivered a programming course to 6 th grade Korean elementary school students using our block system. The results are encouraging.
The Influence of High Plasticity and Expansive Clay Stabilization with Limestone on Unconfined Compression Strength

Clay is a cohesive material that becomes very soft when high content of water is added. This condition makes construction activities difficult on this type of soil. There is, therefore, a need for stabilization when dealing with high plasticity clay through several methods such as the application of limestone. However, this method mostly does not meet the standards due to the reaction between limestone and groundwater which normally alters soil properties, thereby, leading to a reduction in stickiness and softness of the soil. Meanwhile, limestone generally has the ability to compact and stabilize the soil due to its fine powder which consists of metals and nonorganic mineral compositions. Therefore, this study was conducted to identify the influence of using limestone additives for stabilization at different mixture compositions on clay. The properties of the soil were tested before the Unconfined Compression Strength Test and the results showed limestone was effective in stabilizing high plasticity and expansive clay. This was proven by the 10% increase in the Unconfined Compression with lime content in curing conditions for 28 days as well as the 319% magnitude of the non-soaked, 6% reduction in the liquid limit value, and 46% increment in the plastic limit value.

Patients and Methods: Eighty-eight OSA patients aged between 22 and 77 years were enrolled in this study. Nasal resistance was measured at pressures of 75, 150, and 300 Pa, with the patients first in the seated position than in the supine position. Relationships between the oximetric variables and nasal resistance in the seated and supine positions were analyzed. Results: From seated to supine position, a statistically significant increase in nasal resistance was observed at pressures of 75 and 150 Pa (p=0.001 and p=0.006, respectively). Significant positive correlations were noted between nasal resistance in the supine position at 75 Pa (SupineNR75) and oximetry variables, including oxygen desaturation index (ODI, p=0.015) and the percentage of total time with oxygen saturation level lower than 90% (T < 90%, p=0.012). However, significant positive correlations existed only in moderate to severe OSA when the study group was further divided into two subgroups (mild vs moderate to severe OSA). Body mass index (β = 0.476, p<0.001) and SupineNR75 (β = 0.303, p=0.004) were identified as independent predictors for increased ODI. Conclusion: Nasal resistance in the supine position measured at 75 Pa significantly correlated with the severity of oxygen desaturation. Therefore, nasal obstruction may play an important role in the pathophysiology of hypoxemia in OSA patients, especially in patients with moderate to severe OSA.
Finite element model of circularly curved Timoshenko beam for in-plane vibration analysis

Curved beams are used so much in the arches and railway bridges and equipments for amusement parks. There are few reports about the curved beam with the effects of both the shear deformation and rotary inertias. In this paper, a new finite element model investigates to analyze In-Plane vibration of a curved Timoshenko beam. The Stiffness and mass matrices of the curved beam element was obtained from the force-displacement relations and the kinetic energy equations, respectively. Assembly of the elemental property matrices is simple and without need to transformation matrix because of using the local polar coordinate system. The natural frequencies of curved Euler-Bernoulli beam with large thickness are not sufficiently accurate. In this case, using the curved Timoshenko beam element is necessary. Moreover, the influence of vibration absorber is discussed on the natural frequencies of the curved beam.
Thalamic deep brain stimulation modulates circadian and infradian cycles of seizure risk in epilepsy

Chronic brain recordings suggest that seizure risk is not uniform, but rather varies systematically relative to daily (circadian) and multiday (infradian) cycles. Here, one human and seven dogs with naturally occurring epilepsy had continuous intracranial EEG (median 298 days) using novel implantable sensing and stimulation devices. Two pet dogs and the human subject received concurrent thalamic deep brain stimulation (DBS) over multiple months. All subjects had circadian and infradian cycles in the rate of interictal epileptiform spikes (IES). There was seizure phase locking to circadian and infradian IES cycles in five and seven out of eight subjects, respectively. Thalamic DBS modified circadian (all 3 subjects) and infradian (analysis limited to the human participant) IES cycles. DBS modified seizure clustering and circadian phase locking in the human subject. Multiscale cycles in brain excitability and seizure risk are features of human and canine epilepsy and are modifiable by thalamic DBS.
REVISTA DE CONTABILIDAD SPANISH ACCOUNTING REVIEW

This paper reports on a study exploring the relationship between the fixed remuneration paid to the Chief Auditing Executive (CAE), and the subsequent financial reporting quality (FRQ). The study argues from the viewpoint that a strategy of compensation provided on the basis of company performance is detrimental to FRQ, and that when the CAE receives fixed remuneration, there is less threat to internal audit (IA) objectivity, and hence, greater FRQ as proxied by accruals quality. Data are obtained via a survey questionnaire, and information offered within annual reports. The findings indicate that when the CAE is compensated according to company performance, objectivity is reduced, with the consequent outcome that FRQ is impaired. Furthermore, when CAE remuneration and compensation are approved by the audit committee, rather than by the CEO, FRQ is higher. Evidence that the effects of IA objectivity are eliminated when the CEO is involved in approving CAE remuneration and compensation is also found. The study provides insights into the question of whether CAE remuneration enhances IA objectivity, and in doing so is of interest to audit committees with responsibility in that direction. Two different estimation methods are used as a means of confirming the robustness of these results. ©2021 ASEPUC. Published by EDITUM Universidad de Murcia.

Coupling effects of structure, oxygen availability and temperature on microbial growth in a pastry filling

The structure of real food is a key factor to be considered in order to control microbial growth. A pastry filling has been employed as model food to study the growth of Staphylococcus under different conditions. Additionally, the structure of the food system has been characterised by means of rheological measurements. Frequency sweeps showed that, in all cases, the elastic component determines the rheological behaviour of model pastry filling (G' > G''). Values obtained for the coordination number (z) and the proportional coefficient (A) indicated that the model food exhibits more aggregate structures and stronger links at lower temperatures. According to the maximum specific growth rates, the Staphylococcus growth in the model pastry filling was clearly conditioned by oxygen diffusion, which is limited by the food matrix, and also by the incubation temperature. In addition, the analysis of Staphylococcus growth at different temperatures suggested the influence of the pastry filling structure on microorganism behaviour.
Epistemologies in Practice: A Review of the Uses of Big Data in the Political and Social Sciences

The role and value of big data in the social sciences have been a topic of heated discussion for almost a decade now (see e.g. Anderson 2008; Lazer et al. 2009; boyd and Crawford 2012; Floridi 2012; Mayer-Schönberger and Cukier 2013; Kitchin 2014; Burrows and Savage 2014; Frické 2015; Felt 2016; Symons and Alvarado 2016; Wheeler 2017). A question central to the discussion is the issue of whether the availability of large-scale datasets and methods for analyzing them brings about a significant change in the epistemology of the social sciences. For instance, boyd and Crawford claim that
The Impact of Affect on Second Language Learning: A Mixed Methods Case Study

Affect includes every aspect related to feelings, emotions, moods, sensations etc. that people encounter in their lives. University students experience a rich variety of such feelings, emotions, moods and sensations in academic settings. They are also frequently subjected to emotional upheaval due to various reasons, specifically within the initial phase of their university life. Emotions experienced by students in academic settings are believed to play a major role in their academic success and achievement. However, the attention given to the role of emotions in educational settings, particularly in Second Language (L2) learning is seemingly at a low level. Therefore, the study explored the impact of academic emotions on L2 learning with a special focus on first year Undergraduate Officer Cadets studying in a defence university in Sri Lanka. This investigation took the form of a case study that subsumes a mixed methods research design. Both quantitative and qualitative methods to gather, analyse and interpret data were integrated at each stage of the study to avoid inherent biases and limitations of using only one method. Results suggested that especially during the first year, the students frequently encounter many adjustment problems due to the nature of their training, language issues and personal attributes. What appeared to be impacted mostly on real learning in this context was intrinsic motivation. Though manifestation of positive emotions inside the classroom was found to have a positive impact on students’ performance, it was exposed that in educational settings where rigorous physical training is a necessity, the will power and determination gained through the experience of negative emotions seemed to assist the students to perform better in classroom activities, presentations and at exams than the impact made by the experience of positive emotions. It is therefore, recommended the university staff members to intervene in assisting the undergraduates in coping with their emotional struggles only in the right place and at the right time, as enough room should be given to the students to learn from their own affective experiences.
Involving Students in the Instructional Design Process to Improve Their Satisfaction with Their Learning in the COVID-19 Era

Like most university students worldwide, the engineering students at the School of Information Sciences (ESI) have to deal with their school closure and the new paradigm of distance learning. Despite efforts made by the administration and the teachers to accompany students, an internal survey conducted by the end of October 2021 revealed that almost all students, especially first-year ones, did not accept distance learning. This paper describes our experience to improve students’ satisfaction with distance learning by involving them in their courses’ design process. Four courses were concerned by the experience and were designed following the ADDIE method. Last-year students participated in the ADDIE analysis step, while the first-year students participated in the last step by evaluating the co-created courses. Courses were co-created with students as most of them got involved in the ADDIE development step and enriched courses by realizing extras activities. Results showed that students were highly satisfied with courses taught in the context of this study. © 2021 by the authors.
Simultaneous adsorption of methylparaben and propylparaben dyes from aqueous solution using synthesized Albizia lebbeck leaves-capped silver nanoparticles

The Albizia lebbeck leaves-capped silver nanoparticles (ALLC AgNPs) were synthesized, and their applicability for dyes eliminating from aqueous media have been investigated. Identical techniques, including scanning electron microscopy, Fourier transform infrared spectroscopy, and X-ray diffraction analysis, utilized to characterize these novel materials. The ALLC AgNPs were found available, suitable, and bargain-counter adsorbents for the proper removal of methylparaben (MP) and propylparaben (PP) dyes from aqueous media. By examining the effect of different parameters, it was found that the percentage of adsorption and the initial concentrations of MP and PP dyes were inversely related, while the percentage of adsorption and adsorbent dose were directly related. It was shown that the maximum adsorption of MP and PP dyes and their removal by adsorbent was at pH 7.0. The adsorbent dosage of 50 mg in pH 7 has been considered the optimum values for adsorption of MP and PP dyes with a concentration of 10 mg/L onto ALLC AgNPs. The Langmuir model was better at describing equilibrium data than other models. Enthalpy (ΔH°), entropy (ΔS°), and free energy (ΔG°) as thermodynamic parameters of adsorption were determined using isotherms. The fact that the adsorption process was endothermic was well reflected by negative values (ΔG°, ΔH°, and ΔS°), which alone indicated the tendency to synthesize ALLC AgNPs to remove MP and PP dyes. The maximum monolayer coverage capacity (qmax) was 6.7 mg/g for MP and 8.5 mg/g for PP at desired conditions.
XPS Analysis of Stainless Steel Surfaces

The surface chemistry of stainless steel is strongly influenced by the chemical or mechanical processing of that surface. Preventing corrosion is a major ambition of any steel manufacturing process and this is often achieved through passivation. This typically involves the formation of a chromium-rich ‘passive’ layer on the top surface (Figure 1) and there is a number of different methods employed to encourage the growth of such a layer. The key metrics which can be used to identify properly passivated steel are the total Cr/Fe atomic ratio, the Cr oxide/Fe oxide ratio, and the total oxide thickness.
Evaluation of the internal structure of the Serbian version of the Big five questionnaire for children and the development of a short form (SBFQ-C-29): A preliminary study

The personality characteristics of children and adolescents explained by the Big Five model have been studied much less than the personality characteristics of adults. One of the rare self-assessment personality instruments for the preadolescent and adolescent age is the Big Five Questionnaire for Children (BFQ-C). The aim of this study is an evaluation and presentation of the latent structure and some psychometrical characteristics of the BFQ-C in the Serbian language. The sample consisted of 881 participants (54% female) who attended the final grades of primary and the initial grades of secondary schools (M=14 years, SD = .99). The original model, previously addressed across different cultures and languages, was tested through CFA. The hypothesized model did not obtain satisfactory fit indices. Following these results, the sample was randomly divided into two datasets. We opted for further exploration of the Serbian version of BFQ-C's latent structure and the development of its shorter version. The final result is the 29-item questionnaire solution (SBFQ-C-29), with loadings on five factors with satisfactory internal consistency, homogeneity, and adequacy, consistent with the previous studies addressing different cultures and languages.
Obstacles to strategy implementation and success factors: A review of empirical literature

The purpose of this study is to identify obstacles and success factors evident from empirical studies affecting strategy implementation and to provide an overview of the empirical literature. A systematic literature review (SLR) was used to analyze thirty-five peer-reviewed empirical articles. All of the 35 research papers selected in this review use primary data gathered from the organizations studied. This study of empirical research has identified 16 obstacles that can hinder strategy implementation and 18 success factors that can facilitate implementation. This study highlights factors that are dualistic, meaning that they contain both elements of obstacles and key success factors. The dualistic factors should therefore be considered in the strategy implementation process. Research gaps are identified. They include lack of studies on how to overcome obstacles to strategy on the one hand and on employee influence on implementation on the other. The differences among industries, countries, or cultures regarding implementation have not yet been explored at any depth. The paper adds to theoretical and practical knowledge based on the systematic overview it provides on strategy implementation from 1980 until 2020. The paper enriches the practical knowledge relevant to those implementing strategies, as it captures and identifies the dualistic factors affecting strategy implementation.
Flavonoids from aerial part of Algerian Ajuga iva (L.) schreb.: The HPLC-UV analysis and Antioxidant capacity

The study deals with the evaluation of the antioxidant capacity of extracts from the aerial part of Algerian Ajuga iva. Extraction of flavonoids was carried out by 85% of methanol, then the crude extract was successively separated with ethyl acetate, butanol, and water. The in vitro antioxidant activity was assessed by 1,1-diphenyl-2picrylhydrazyl, reducing power, and thiobarbituric acid reacting substances assays. Extracts are subject to HPLC-UV analysis. The average total phenol contents of extracts vary between 3.87 ± 0.17 and 149.74 ± 3.94 (gallic acid equivalent per gram of dry extract). Furthermore, tested extracts exhibited a broad range of flavonoid contents varying from 1.54 ± 0.09 to 41.18 ± 1.03 (catechin equivalent per gram of dry extract). Butanol and ethyl acetate fractions displayed the highest antioxidant activity. A good correlation between the phenolic and flavonoid contents and the antioxidant activity was observed. Rutin, caffeic acid, quercetin, p-coumaric acid, luteolin, and cinnamic acid were present in the extracts. The plant could be a potential source of antioxidant agents.
