The cost of care for children hospitalised with Invasive Group A Streptococcal Disease in Australia
Authors: Brusco Natasha K. , Oliver Jane , McMinn Alissa , Steer Andrew , Crawford Nigel
Published: December 2021

Background

Invasive Group A Streptococcal (iGAS) disease exerts an important burden among Australian children. No Australian hospitalisation cost estimates for treating children with iGAS disease exist, so the financial impact of this condition is unknown.

Aim

To determine the minimum annual healthcare cost for children (< 18 years) hospitalised with iGAS disease in Australia from a healthcare sector perspective.

Methods

A cost analysis including children with laboratory-confirmed iGAS disease hospitalised at the Royal Children’s Hospital (Victoria, Australia; July 2016 to June 2019) was performed. Results were extrapolated against the national minimum iGAS disease incidence. This analysis included healthcare cost from the 7 days prior to the index admission via General Practitioner (GP) and Emergency Department (ED) consultations; the index admission itself; and the 6 months post index admission via rehabilitation admissions, acute re-admissions and outpatient consultations. Additional extrapolations of national cost data by age group, Aboriginal and Torres Strait Islander ethnicity and jurisdiction were performed.

Results

Of the 65 included children, 35% (n = 23) were female, 5% (n = 3) were Aboriginal and Torres Strait Islander, and the average age was 4.4 years (SD 4.6; 65% aged 0–4). The iGAS disease related healthcare cost per child was $67,799 (SD $92,410). These costs were distributed across the 7 days prior to the index admission via GP and ED consultations (0.2 and 1.1% of total costs, respectively), the index admission itself (88.7% of the total costs); and the 6 months post index admission via rehabilitation admissions, acute re-admissions and outpatient consultations (5.3, 4.5 and 0.1% of total costs, respectively). Based on a national minimum paediatric incidence estimation of 1.63 per 100,000 children aged < 18 (95%CI: 1.11–2.32), the total annual healthcare cost for children with iGAS in 2019 was $6,200,862. The financial burden reflects the overrepresentation of Aboriginal and Torres Strait Islander people in the occurrence of iGAS disease. Costs were concentrated among children aged 0–4 years (62%).

Conclusion

As these cost estimations were based on a minimum incidence, true costs may be higher. Strengthening of surveillance and control of iGAS disease, including a mandate for national notification of iGAS disease, is warranted.

Trial registration

The current study is a part of ongoing iGAS surveillance work across seven paediatric health services in Australia. As this is not a clinical trial, it has not undergone trial registration.
Atypical drainage of a persistent left vena cava superior into the left atrial appendage detected by multidimensional imaging: a case report and review of the literature
Authors: Lengning Sophie , Aschenbach René , Schulze P. Christian , Franz Marcus
Published: December 2021

Background

While it is the most common thoracic venous anomaly, a persistent left vena cava superior may present in atypical variations, which are important to consider during clinical management.

Case presentation

Here we report a 35-year-old Caucasian female patient with drainage into the left atrial appendage who presented with shortness of breath accompanied by mild hypoxemia. Venous contrast filling in the context of pulmonary scintigraphy suspected an additional superior caval vein connected to the left atrial appendage. Diagnosis was confirmed by transesophageal echocardiography. Cardiac catheterization revealed a minor right-to-left shunt. The symptoms could be allocated to a bronchial asthma and treated according to guidelines. Cerebral lesions detected in the patient were due to a coincident multiple sclerosis rather than cerebral embolisms. Thus, the venous anomaly was classified as an incidental finding currently requiring no treatment.

Conclusions

To the best of our knowledge, this is the first report of a persistent left vena cava superior draining into the left atrial appendage.

Published: December 2021

Background

Peripheral artery disease (PAD) is a serious complication in hemodialysis (HD) patients. Low skin perfusion pressure (SPP) is a useful marker for detecting PAD. Malnutrition is an important cause of intractable complications. We examined the relationship between low SPP and various indicators of nutritional status.

Methods

A total of 120 patients on maintenance HD were enrolled for SPP measurement. SPP was measured at the soles of both feet during HD, and patients were divided into low SPP (L-SPP) and normal SPP (N-SPP) groups by 50 mmHg. The following values were determined by averaging four blood samples taken before SPP measurements every 3 months for one year: hemoglobin, total protein, albumin (Alb), total cholesterol, urea nitrogen, creatinine (Cr), potassium, calcium, phosphate, intact parathyroid hormone, iron (Fe), transferrin saturation (T-SAT), and C-reactive protein (CRP). We calculated the percent Cr production rate, dialysis index (Kt/V), normalized protein catabolic rate (nPCR), geriatric nutritional risk index (GNRI), and estimated salt intake using the required formulas. In addition, the age, body mass index, and presence of diabetes mellitus (DM) were compared between both groups along with all other measurements. Data were expressed as the mean ± standard deviation or median with interquartile range as appropriate. Differences in continuous variables between the two groups were analyzed by Student’s t-test or Wilcoxon’s rank-sum test, as appropriate. Multivariate logistic analysis and receiver operating curve (ROC) analysis were performed for significant variables. The results were expressed as odds ratios with respective 95% confidence intervals (CIs).

Results

The enrolled patients were 82 men and 38 women, with a mean age of 66.9 ± 13.3 years and HD duration of 4.76 (2.13–12.28) years (median interquartile range). Twenty patients belonged to the L-SPP group, suggesting PAD. Comparison between the L-SPP and N-SPP groups showed significant differences in age, Cr, Fe, T-SAT, CRP, nPCR, GNRI, DM, and estimated salt intake. When the GNRI, estimated salt intake, CRP, and DM were applied as independent variables for multiple logistic regression analysis, the GNRI (odds ratio: 0.857, 95% CI 0.781–0.941, p = 0.001), CRP (2.406, 1.051–3.980, p = 0.035), and DM (9.194, 2.497–33.853, p = 0.001) were found to be significant for L-SPP, and a cutoff level of 92.1 (sensitivity 80%, specificity 72%, AUC: 0.742, 95% CI 0.626–0.858, p = 0.001) in the GNRI obtained by ROC was consistent with the risk index in the elderly presented previously.

Conclusions

SPP measurement is an essential tool for detecting high-risk PAD in maintenance HD, which is affected by malnutrition, DM, and inflammation. The GNRI is important for the determination of malnutrition.
Optimal reactive power dispatch using a novel optimization algorithm
Authors: Roy Ranjit , Das Tanmay , Mandal Kamal Krishna
Published: December 2021

The problem of optimal reactive power dispatch (ORPD) is one of the most popular and widely discussed problem in power system engineering all over the world. Optimal reactive power dispatch is one of the sub-problems of the optimal power flow which is complex and nonlinear problem, which can be formulated as both single- and multi-objective. In this paper, the problem has been formulated as a single-objective problem to minimize the active power losses in the transmission lines. A recently proposed powerful and reliable meta-heuristic algorithm known as the JAYA algorithm has been applied to solve the ORPD problem. The algorithm has been applied on the standard IEEE 14, 30, 57 and 118 bus systems. The simulation results using the proposed algorithm when compared with the results from other algorithms and few others reported in the literature prove that the JAYA algorithm is the most superior among all.

Published: December 2021

Introduction. Comorbidity is an independent risk factor for mortality and significantly influences the prognosis and quality of life.
Purpose: to evaluate the impact of high-tone HiTOP 4 touch therapy on cognitive disorders and quality of life in the complex treatment of patients with comorbid pathology.
Methods: complex treatment of 2 groups of patients with inclusion in the basic treatment regimen of high-tone therapy was carried out - a total of 80 patients (men - 34, women - 46) aged 41 to 79 years old, group I - patients with hypertension and chronic cerebral ischemia (CСI) - 38 patients and group II - patients with hypertension, CСI and concomitant diabetes mellitus (DM) type 2 - 42 patients. The average age in group I was 61.5, in group II - 65.5. Group I received lisinopril and amlodipine in one tablet, group II received metformin in addition to the above therapy. Both groups received a course of 10 sessions of high-tone therapy using the device HiTOP 4 touch (Germany) according to the general method: 2 electrodes on the feet, 2 on the forearms and one on the neck-collar area. All the patients were assessed for their cognitive condition, degree of anxiety and depression, and estimated for quality of life before and after a course of high-tone therapy. In order to do this, we used valid assessment tests, such as the Montreal Cognitive Assessment Scale (MoCA), the Hospital Anxiety and Depression Scale (HADS), and the SF-36 Quality of Life Questionnaire. Results: the course of high-tone therapy for patients with hypertension and CCI led to improved quality of life, on all indicators of the SF-36 scale, except for pain intensity, increased cognitive functions by 3.52 points on the MoCA scale, reduced anxiety by 2.06 points and depression by 1.92 points on the HADS scale. The course of high-tone therapy for patients with CCI, hypertension and type 2 DM resulted in a significant improvement of 5 out of 8 quality of life indicators on the SF-36 scale, cognitive functions by 2.27 points on the MoCA scale and reduced anxiety by 4.3 points, and depression by 0.53 points on the HADS scale.
Conclusion: the inclusion of high-tone therapy in the complex treatment of patients with comorbid pathology improves cognitive functions, reduces anxiety and depression, improves quality of life.

Complex aspects of clinical-functional evaluation and ambulatory therapeutic-rehabilitation approach in a young patient with post stroke - spasticity and peroneal nerve palsy
Authors: ALBADI Irina , CIOBOTARU Camelia , LUPU Andreea-Alexandra , ONOSE Gelu
Published: December 2021

Introduction. Spasticity, a common post-stroke complication associated with signs and symptoms of upper motor neuron syndrome (1), occurs with a 35% prevalence one year after brain injury (2) and can be severely disabling in young patients (3), regarding locomotor dysfunction and also regarding the quality of life. Stroke incidence in young patients increased in the last decades, being correlated with the increasing substance abuse and sedentariness, excessive alcohol consumption, and smoking (4). Peroneal nerve palsy is the most common cause of neuropathy of the lower limb and, in most cases, is caused due to nerve lesion in the fibula head area (5).
Material and method. We present the complex case of a young male patient, former alcohol and narcotics user, who suffered an ischemic stroke in the right middle cerebral artery teritory along with a posttraumatic paresis of the right peroneal nerve. The patient presents motor deficit – right spastic hemiplegia, right foot drop, locomotion and self-care disorders.
Results and discussions. The patient followed medical treatment (antiepileptic, neurotrophic factors, vitamins, antiplatelet) and rehabilitation treatment adapted to the current clinical-functional status (thermotherapy, lasertherapy, magnetotherapy and individual kinesiotherapy), with slow favorable evolution of the improvement of locomotion and quality of life disorders. Conclusions. Therapeutic-rehabilitation management of the spastic patient with disability due to brain injury and peripheral traumatic neuropathy represents a challenge because it doesn’t exist a miraculous treatement (yet) to cure completely these nervous injuries.

Introduction.Recently, the emphasis has been on the problems faced by performance athletes with physical deficiencies of the spine. The aim of the paper is to train coaches in awareness of physical problems, especially of the spine in swimming athletes aged 10-12 years and the development of kinetic programs on land in order to correct them.
Material and method. Research on the effectiveness of kinetic programs as means of correction are very numerous and, in this regard, we aim to select the most effective exercises to correct deficiencies acquired by swimmers and change the functional parameters of the cardio-respiratory system during their training. In order to highlight the need for kinetic correction programs, the coach must work in collaboration with the sports doctor and the physiotherapist in order to prevent possible deviations from normal somatic-functional values.
Results and discussions. Regarding the estimation of the adaptive possibilities of the cardio-respiratory capacity, hence the need to apply a complex of tests to assess the effort capacity of athletes.
Conclusions. In this sense, we will submit to the study the performance group from the University Sports Club from Suceava, and the recovery programs will take place within the Swimming and Kinesiology Complex, Suceava.

Οι πυρήνες των πρώιμων αντιδραστήρων πυρηνικής σχάσης έρευνας και παραγωγής με επιβραδυντή τον γραφίτη στο Ηνωμένο Βασίλειο, λειτουργούσαν σε θερμοκρασίες κάτω των 150°C. Λόγω αυτής της χαμηλής θερμοκρασίας, ο γραφίτης του πυρήνα τους περιέχει σημαντικές ποσότητες αποθηκευμένης ενέργειας (Wigner) που μπορεί να απελευθερωθεί με τη θέρμανση του γραφίτη πάνω από τη θερμοκρασία ακτινοβόλησης. Αυτή η εξώθερμη συμπεριφορά οδήγησε σε μια σειρά ζητημάτων κατά τον παροπλισμό τους, που σχετίζονται με τη μακροπρόθεσμη «ασφαλή αποθήκευση», την αποσυναρμολόγηση του πυρήνα του αντιδραστήρα, τη συσκευασία των απορριμμάτων γραφίτη και την τελική διάθεση των ακτινοβολημένων αποβλήτων γραφίτη. Η απελευθέρωση της αποθηκευμένης ενέργειας μπορεί να μοντελοποιηθεί χρησιμοποιώντας κινητικά μοντέλα. Αυτά τα μοντέλα βασίζονται σε εμπειρικά δεδομένα που λαμβάνονται είτε από δείγματα γραφίτη που έχουν ακτινοβοληθεί σε αντιδραστήρες δοκιμών υλικών (MTR) είτε σε δεδομένα που λαμβάνονται από μικρά δείγματα που λαμβάνονται από τους ίδιους τους αντιδραστήρες. Τα δεδομένα από αυτά τα πειράματα χρησιμοποιούνται για την εξαγωγή των ενεργειών ενεργοποίησης και των χαρακτηριστικών συναρτήσεων των αντιδράσεων απελευθέρωσης που χρησιμοποιούνται σε κινητικά μοντέλα. Η παρούσα διατριβή περιλάμβανε την ανάπτυξη κατανόησης των διαφορετικών ποιοτήτων γραφίτη, τη συσχέτιση της συσσώρευσης αποθηκευμένης ενέργειας με το ιστορικό λειτουργίας του αντιδραστήρα και τη διερεύνηση ιστορικών δεδομένων πειραμάτων απελευθέρωσης αποθηκευμένης ενέργειας. Η απελευθέρωση της αποθηκευμένης ενέργειας στις διάφορες συνθήκες που ισχύουν κατά τον παροπλισμό του αντιδραστήρα έχει διεξαχθεί με τη χρήση τεχνικών θερμικής ανάλυσης όπως η θερμιδομετρία διαφορικής σάρωσης (DSC). Αναπτύχθηκαν, επικυρώθηκαν και εφαρμόστηκαν κινητικά μοντέλα, κατάλληλα για τη μελέτη της απελευθέρωσης της αποθηκευμένης ενέργειας σε ακτινοβολημένα υπολείμματα γραφίτη. Αναπτύχθηκε μια δυνητικά έγκυρη μέθοδος, για τον προσδιορισμό του αποθηκευμένου ενεργειακού περιεχομένου των συστατικών του γραφίτη και της κινητικής της απελευθέρωσης ενέργειας. Μια άλλη παράμετρος που διερευνήθηκε σε αυτή τη μελέτη ήταν αφιερωμένη στην προσομοίωση της βλάβης από ακτινοβολία χρησιμοποιώντας ακτινοβολία ιόντων. Ο βομβαρδισμός ιόντων μικρών δειγμάτων γραφίτη είναι μια προσβάσιμη μέθοδος προσομοίωσης της βλάβης από ακτινοβολία ταχέων νετρονίων. Προκειμένου να αποκτηθει εμπιστοσύνη ότι η βλάβη από την ακτινοβολία ιόντων είναι ένα καλό μοντέλο προσομοίωσης για τη βλάβη από ακτινοβολία νετρονίων, διερευνήθηκαν επίσης οι ιδιότητες και η μικροδομή διαφόρων τύπων πυρηνικού γραφίτη που ακτινοβολήθηκε με ιόντα. Η φασματοσκοπία Raman χρησιμοποιήθηκε για να συγκριθούν τα αποτελέσματα του βομβαρδισμού ιόντων με τα αναφερόμενα από την βιβλιογραφία αποτελέσματα της ακτινοβολίας νετρονίων. Οι αλλαγές στην περιεκτικότητα σε ασυνέχειες πλέγματος με τη θερμική ανόπτηση του ακτινοβολούμενου γραφίτη με ιόντα, συγκρίθηκαν με την ανόπτηση του πυρηνικού γραφίτη ακτινοβολημένου με νετρόνια.

Θέμα αυτής της εργασίας είναι ο τρόπος που λειτουργεί ο συμβολισμός στις επίσημες αναπαραστάσεις των γιων και των θυγατέρων των Φαραώ, κατά την ιστορική περίοδο η οποία είναι γνωστή ως Νέο Βασίλειο (1550-1069 π.Χ.).Η χρήση συμβόλων σε διαφορετικές εκφράσεις του αιγυπτιακού πολιτισμού έχει αναφερθεί ευρέως και έχει συζητηθεί από πολλές διαφορετικές οπτικές γωνίες. Οι μελετητές έχουν επίσης αναλύσει την ταυτότητα και τη λειτουργία διαφόρων βασιλικών απογόνων μέσα από εργασίες ιστορικής και γενεαλογικής θεματικής. Ωστόσο, έχει γίνει ελάχιστη προσπάθεια να συσχετιστούν γενικές ιδέες για τον οπτικό και λεκτικό συμβολισμό με τοςυ βασιλικούς απογόνους ως μια κοινωνικά ομοιογενή ομάδα. Ως εκ τούτου, αυτό το έργο στοχεύει να διερευνήσει και να εξηγήσει τι κρύβεται κάτω από την επιλογή, την παραλλαγή και την εξέλιξη των συμβόλων που χρησιμοποιούνται στην εικονογραφία των βασιλικών απογόνων.Στα πέντε κεφάλαια αυτού του βιβλίου, οι απόγονοι των φαραώ εξετάζονται αρχικά σε σχέση με λογοτεχνικές και μυθολογικές αναφορές σε θεϊκές και βασιλικές οικογένειες. Μέσα από μια πρωτοποριακή μεθοδολογία και τη χρήση ενός λεπτομερούς καταλόγου εικόνων, η συγγραφέας εξηγεί τον τρόπο με τον οποίο οι βασιλικοί απόγονοι εντάσσονται στην αρχαία αιγυπτιακή κοσμική-ταξική διαστρωμάτωση ως σύνδεσμος μεταξύ του βασιλιά και των θνητών και το ρόλο που έπαιξαν στην επίσημη βασιλική προπαγάνδα.

Η οικονομική κρίση/ύφεση και η πολιτική αστάθεια είναι δύο αλληλένδετες έννοιες με κοινά χαρακτηριστικά. Η πρόσφατη χρηματοπιστωτική και οικονομική κρίση χαρακτηρίζεται από μια περίπλοκη σχέση μεταξύ μακροοικονομικής και πολιτικής αστάθειας. Η μία αστάθεια αναπαράγει την άλλη, συχνά με ανατροφοδότηση, η οποία δημιουργεί αυτόνομους κύκλους.Αυτή η διατριβή πιστεύει ότι η πολιτική αστάθεια και οι οικονομικές κρίσεις/υφέσεις έχουν άμεση σχέση, διότι χωρίς ένα σταθερό πολιτικό περιβάλλον, οι κρίσεις είναι δύσκολο να αντιμετωπιστούν σε μια χώρα. Επιπλέον, αυτές ενδέχεται να επηρεάσουν αρνητικά το πολιτικό σύστημα, οδηγώντας έτσι σε πολιτική αστάθεια. Υποστηρίζεται επίσης μια ισχυρή σχέση μεταξύ των οικονομικών κρίσεων/υφέσεων καθώς και της πολιτικής αστάθειας.Λαμβάνοντας υπόψη τα ανωτέρω, ο σκοπός αυτής της διατριβής μπορεί να προσδιοριστεί με δύο τρόπους α) την εκτίμηση του αντίκτυπου της πρόσφατης οικονομικής κρίσης και ύφεσης του 2007/2008, που μετρήθηκε με διάφορους τρόπους, στο χρηματιστήριο, χρησιμοποιώντας διαφορετικές καινοτόμες οικονομετρικές μεθοδολογίες και διατηρώντας το δείγμα σταθερό και β) την αντιμετώπιση του προβλήματος της πολυδιάστατης πολιτικής αστάθειας προτείνοντας νέα μέτρα και δείκτες πολιτικής αστάθειας, προκειμένου να εκτιμηθεί ο αντίκτυπός στην χρηματοπιστωτική αγορά, την αύξηση του ΑΕΠ και τις άμεσες ξένες επενδύσεις.Το εμπειρικό μέρος ξεκινά με τη χρήση των Differences-in-Differences (DID) και Changes-in-Changes (CIC) προσεγγίσεων, για να εκτιμηθεί ο αντίκτυπος της οικονομικής κρίσης/ύφεσης στους τραπεζικούς και γενικούς χρηματιστηριακούς δείκτες. Οι περίοδοι της πρόσφατης κρίσης μετρήθηκαν με τέσσερις διαφορετικούς τρόπους και ελήφθησαν από διάφορες βάσεις δεδομένων που χρησιμοποιούνται στην αντίστοιχη βιβλιογραφία. Συνεχίζει με τη χρήση διαφόρων μεταβλητών πολιτικής αστάθειας από την αντίστοιχη βιβλιογραφία, για την δημιουργία πέντε νέων δεικτών πολιτικής αστάθειας. Χρησιμοποιούνται η Exploratory Factor Analysis και η Principal Component Analysis. Οι δείκτες εφαρμόστηκαν στις χρηματιστηριακές αγορές, την μεταβλητότητά τους, την αύξηση του ΑΕΠ και τις άμεσες ξένες επενδύσεις, ώστε να εκτιμηθεί ο πιθανός αντίκτυπός του.Τα αποτελέσματα της εκτίμησης παρέχουν επιβεβαιωτικά στοιχεία για την εγκυρότητα της προτεινόμενης θεωρίας. Τα συμπεράσματα παρέχουν επίσης στοιχεία ότι οι κρίσεις/υφέσεις επηρεάζουν άμεσα τις χρηματοπιστωτικές αγορές και ότι η πολιτική αστάθεια είναι ένα πολυδιάστατο πρόβλημα που ποικίλλει από χώρα σε χώρα.
Δημιουργία περιβαλλόντων μάθησης με την αξιοποίηση εργαλείων της τεχνολογίας Web 2.0

Μέσα από τη χρησιμοποίηση της δημοφιλούς γλώσσας προγραμματισμού java, κατασκευάστηκε μια ψηφιακή εκδοχή του παιχνιδιού στρατηγικής ΝΙΜ. Ακολούθως, αναπτύχθηκε ένα διδακτικό σενάριο διδακτικής αξιοποίησης της ψηφιακής εκδοχής του παιχνιδιού, στο οποίο κεντρική θέση είχε η χρησιμοποίηση διαλογικών δραστηριοτήτων. Γενικότερη επιδίωξη της διδακτικής παρέμβασης υπήρξε η καλλιέργεια της μαθηματικής σκέψης των μαθητών, ενώ ειδικότερους στόχους αποτέλεσαν η βελτίωση της ικανότητας επίλυσης προβλημάτων και η δημιουργία ευκαιριών για παραγωγή συλλογισμών και διατύπωση επιχειρημάτων. Με βάση τα παραπάνω, σκοπό της διατριβής αποτέλεσε η εις βάθος μελέτη αυτής της περίπτωσης όπου έγινε διδακτική αξιοποίηση μίας παιγνιώδους εφαρμογής πολυμέσων που δημιουργήθηκε από τον εκπαιδευτικό της σχολικής τάξης. Επιδίωξη του ερευνητή ήταν να παρουσιαστεί λεπτομερώς ο τρόπος συμμετοχής των μαθητών στις επιμέρους δραστηριότητες, καθώς και το κατά πόσον η παρέμβαση αυτή συνολικά μπόρεσε να συμβάλλει στην ανάδειξη της μαθηματικής σκέψης των μαθητών. Η μεθοδολογία έρευνας που ακολουθήθηκε ήταν η μελέτη περίπτωσης, με στόχο την παροχή μιας όσο το δυνατόν πιο πυκνής περιγραφής της δραστηριότητας που αναπτύχθηκε στο παραπάνω πλαίσιο, από τους μαθητές ενός τμήματος Ε΄ τάξης δημοτικού που αποτέλεσε το δείγμα της έρευνας. Για την επίτευξη του παραπάνω στόχου αξιοποιήθηκαν τόσο ποσοτικά δεδομένα (δοκιμασία εκτίμησης της γενικότερης ικανότητας επίλυσης προβλημάτων και της ειδικότερης ικανότητας στο παιχνίδι ΝΙΜ, ερωτηματολόγια, κοινωνιομετρική τεχνική) όσο και ποιοτικά δεδομένα (ατομικές συνεντεύξεις, συζητήσεις στην ολομέλεια της τάξης και σε περιβάλλον chat, τεχνική ομιλούντος υποκειμένου, παρατήρηση), καθώς επίσης και στοιχείων που προέκυψαν από την ανάλυση των ίδιων των παιχνιδιών ΝΙΜ των μαθητών. Με βάση την ανάλυση των αποτελεσμάτων διαφαίνεται ότι οι μαθητές που συμμετείχαν στην έρευνα παρουσίασαν σημαντική βελτίωση τόσο της ικανότητάς τους στο παιχνίδι ΝΙΜ όσο και της γενικότερης ικανότητας επίλυσης προβλημάτων. Το μέγεθος της παρατηρούμενης βελτίωσης φάνηκε να σχετίζεται με παράγοντες όπως η ικανότητα των μαθητών στα μαθηματικά (όπως προέκυψε από τις εκτιμήσεις των εκπαιδευτικών), καθώς επίσης και ο βαθμός εξοικείωσής των μαθητών με παιχνίδια γρίφων και στρατηγικής. Ταυτόχρονα, η ανάλυση των διαλόγων έδειξε ότι οι μαθητές προοδευτικά βελτίωσαν τον τρόπο με τον οποίο συμμετείχαν στις διαλογικές δραστηριότητες, δείχνοντας σταδιακά να υιοθετούν βασικές κοινωνικομαθηματικές νόρμες που θεωρούνται προαπαιτούμενες για την ανάπτυξη παραγωγικών μαθηματικών συζητήσεων. Επιπλέον, μέσα από την αξιοποίηση του σχήματος επιχειρηματολογίας του Toulmin, εντοπίστηκε ένα σύνολο εκφορών όπου οι μαθητές κατάφεραν να διατυπώσουν συλλογισμούς κάνοντας χρήση συγκεκριμένων επιχειρηματολογικών σχημάτων.
K-way Balanced Graph Partitioning for Parallel Computing
Authors: Patil Siddheshwar Vilas , Kulkarni Dinesh B.
Published: December 2021

In modern computing, high-performance computing (HPC) and parallel computing require most of the decision-making in terms of distributing the payloads (input) uniformly across the available set of resources, majorly processors; the former deals with the hardware and its better utilization. In parallel computing, a larger, complex problem is broken down into multiple smaller calculations and executed simultaneously on several processors. The efficient use of resources (processors) plays a vital role in achieving the maximum throughput which necessitates uniform load distribution across available processors, i.e. load balancing. The load balancing in parallel computing is modeled as a graph partitioning problem. In the graph partitioning problem, the weighted nodes represent the computing cost at each node, and the weighted edges represent the communication cost between the connected nodes. The goal is to partition the graph G into k partitions such that: I) the sum of weights on the nodes is approximately equal for each partition, and, II) the sum of weights on the edges across different partitions is minimum.  In this paper, a novel node-weighted and edge-weighted k-way balanced graph partitioning (NWEWBGP) algorithm of  O(n x n)  is proposed. The algorithm works for all relevant values of k, meets or improves on earlier algorithms in terms of balanced partitioning and lowest edge-cut. For evaluation and validation, the outcome is compared with the ground truth benchmarks.

Published: December 2021

Over the past years, Cloud computing has become one of the most influential information technologies to combat computing needs because of its unprecedented advantages. In spite of all the social and economic benefits it provides, it has its own fair share of issues. These include privacy, security, virtualization, storage, and trust. The underlying issues of privacy, security, and trust are the major barriers to the adoption of cloud by individuals and organizations as a whole. Trust has been the least looked into since it includes both subjective and objective characteristics. There is a lack of review on trust models in this research domain. This paper focuses on getting insight into the nomenclature of trust, its classifications, trust dimensions and throws an insight into various trust models that exist in the current knowledge stack. Also, various trust evaluation measures are highlighted in this work. We also draw a comparative analysis of various trust evaluation models and metrics to better understand the notion of trust in cloud environments. Furthermore, this work brings into light some of the gaps and areas that need to be tackled toward solving the trust issues in cloud environments so as to provide a trustworthy cloud ecosystem. Lastly, we proposed a Machine Learning backed Rich model based solution for trust verification in Cloud Computing. We proposed an approach for verifying whether the right software is running for the correct services in a trusted manner by analyzing features generated from the output cloud processed data. The proposed scheme can be utilized for verifying the cloud trust in delivering services as expected that can be perceived as an initiative towards trust evaluation in cloud services employing Machine learning techniques. The experimental results prove that the proposed method verifies the service utilized with an accuracy of 99%.

Introducción: como ocurrió en 1918, cuando la epidemia de gripa llegó a la capital colombiana, la actual pandemia de la covid-19 demostró que si bien la enfermedad ataca indiscriminadamente a la población, las clases populares se ven particularmente expuestas teniendo en cuenta sus condiciones de vida. Desarrollo: en el artículo se analizan los discursos que, con motivo de la epidemia de gripa de 1918, se construyeron alrededor de las clases populares capitalinas. La aproximación a las fuentes primarias, en especial a la prensa gráfica de la época, permite dar cuenta de la precariedad con la que los pobres, ubicados en un sector periférico y deprimido de la ciudad, debieron enfrentar una enfermedad letal que causó gran desconcierto y que avanzó rápidamente a lo largo y ancho de una ciudad que carecía de un servicio médico público. Por su parte, las élites bogotanas que, bajo el discurso de la caridad cristiana pretendieron atenuar la crisis, responsabilizaron a los pobres de su suerte por su falta de higiene, su imprevisión y su desorden. Conclusiones: hoy, un siglo después de la epidemia de gripa en Bogotá y en medio de la pandemia de la covid-19, se ha evidenciado, ante una serie de medidas ordenadas por el Gobierno nacional y por el Gobierno local, que incluyen cuarentenas obligatorias, la permanencia de visiones y discursos en los que los enfermos pobres, lejos de ser comprendidos en su realidad social, siguen viéndose como un peligro para el resto de la sociedad.
¿Trabajadoras o heroínas? Cuidados sanitarios en tiempos de crisis
Authors: Ramacciotti Karina , Testa Daniela
Published: December 2021

Introducción: el artículo reflexiona sobre las tensiones que atraviesan las profesiones vinculadas a los cuidados sanitarios en situaciones de crisis acontecidas en la historia de Argentina. Se consideran tres momentos en los cuales, ante situaciones de crisis políticas, epidemias y catástrofes naturales, las mujeres, en su rol naturalizado de cuidadoras, tuvieron un desempeño más visible. Desarrollo: se analiza la participación de una de las primeras médicas argentinas, Elvira Rawson, durante la Revolución del Parque (26 de julio de 1890, Buenos Aires) cuando, aun siendo estudiante, desafió los criterios establecidos y atendió heridos de bala sin distinguir filiación política. Luego, se reflexiona sobre el papel de un grupo de enfermeras (argentinas y estadounidenses) durante la epidemia de poliomielitis en 1943 y la creación de un controvertido método de rehabilitación ideado por una enfermera, Elizabeth Kenny. Por último, se examina al terremoto sucedido en la provincia de San Juan, en 1944, como un escenario que convocó vocaciones solidarias y estimuló el desarrollo de la enfermería en Argentina. Conclusiones: la retórica de la “vocación”, el “amor al prójimo” o las “dotes naturalizadas otorgadas por el sexo” sue- len ser rasgos que se acentúan durante crisis políticas, sociales y sanitarias. La pandemia de COVID-19 renueva estrategias discursivas heroicas y sacrificiales que son insuficientes para reconocer los saberes profesionales asociados con las tareas de cuidados, al tiempo que ocultan las malas condiciones de trabajo y las desigualdades sexo-genéricas que se reproducen en el campo sociosanitario.
High Impact Practices and Professional School Acceptance in Health Science Concentrations
Authors: Richard Lori H. , Plaisance Jennifer M. , Scott Brigett , Poché Ruston J.
Published: December 2021

Graduate-level professional health care programs have a highly selective admissions process. Applicants can distinguish themselves by participating in High Impact Practices (HIPs) to enhance their undergraduate experience and academic and professional success. The variables analyzed in this study included acceptance, grade point average (GPA), minor attainment, items from the National Survey of Student Engagement (NSSE), and HIPs. Results of the analysis indicate a significant positive association between professional school acceptance and GPA, minor attainment, and capstone course completion. Data analysis suggests specific HIPs correlate with admission to desired graduate programs, and implications for advising students with this goal are discussed.
Navigating College with MAAPS: Students' Perceptions of a Proactive Advising Approach
Authors: Van Jura Matt , Prieto Kaity
Published: December 2021

In 2016, State University (a pseudonym) implemented a proactive advising approach known as Monitoring Advising Analytics to Promote Success (MAAPS). The initiative was designed to improve academic achievement and retention measures for first-generation students and students from limited-income backgrounds. Using a qualitative methodological design, the purpose of this study was to learn about students' experiences with MAAPS advisors and their overall perceptions of the program. Findings confirm prior research that suggests some students may benefit from advisors' proactive communications and holistic approach. However, the design and implementation of MAAPS discouraged many from participating in the initiative, highlighting several implications for improved future practice.
Opinião Pública e Política Externa: Do Consenso de Almond-Lippmann às Redes Sociais l Public Opinion and Foreign Policy: From The Almond-Lippmann Consensus to Social Media
Authors: Ferreira Alves Gustavo Jordan
Published: December 2021

Neste artigo apresento uma linha cronológica que debate a relação entre opinião pública e temas de política externa ao longo das décadas. Demonstro as teorizações que trabalham com o consenso de Almond-Lippmann até as mais recentes teorias sobre opinião pública na era das redes sociais. Utilizando metodologias quantitativas e qualitativas, principalmente através de uma revisão da literatura já consolidada, apresento a conclusão de que em tal cronologia prevalece a perspectiva de que os eleitores de democracias como os Estados Unidos ou Brasil são majoritariamente desatentos a temas internacionais, mas não necessariamente irracionais em tais assuntos. Nesse sentido, no atual quadro de polarização política, em que mandatários como Donald Trump (2017-2021) e Jair Bolsonaro (2019-) utilizam massivamente redes sociais, surgem novos questionamentos nesse debate, desafiando o papel da mídia tradicional, especialmente depois da popularização dessas novas ferramentas de comunicação.Palavras-chave: Opinião Pública; Política Externa; Mídia.ABSTRACTIn this paper, it is presented a chronology that debates the relation between public opinion and foreign affairs subjects throughout the decades. I demonstrate theories starting from the Almond-Lippmann consensus until more recent ones discussing public opinion on the social media age. By using quantitative and qualitative methodologies, specially through reviewing the literature about public opinion and foreign policy that along the decades became reference in this realm, it is possible conclude that prevails the perspective that voters from democracies such as the United States and Brazil are mostly inattentive in international matters, however, they are not necessarily irrational. In this sense, the recent process of polarization in politics, where leaders such as Donald Trump (2017-2021) and Jair Bolsonaro (2019-) are constantly using social media, brings new questionings to this debate, challenging the role of the traditional media, especially after the popularization of those new communication tools.Keywords: Public Opinion; Foreign Policy; Media. Recebido em: 27/03/2021 | Aceito em: 17/08/2021.
E as mulheres? Uma Perspectiva Feminista Sobre a Resolução de Conflitos Armados l What About Women? A Feminist Perspective on Armed Conflict Resolution
Authors: Alves de Oliveira Mariana Germana Miquelino
Published: December 2021

Neste artigo, buscamos entender as implicações das relações de gênero para a resolução de conflitos armados e as possíveis contribuições resultantes da inclusão de mulheres nos processos de paz. À luz das teorias feministas das Relações Internacionais, propomos a hipótese de que não se pode compreender amplamente as dinâmicas de um conflito armado sem considerar a influência das relações de gênero para a sua eclosão e continuidade e, por conseguinte, não se pode implementar medidas de resolução que sejam plenamente eficientes. Mais do que isso, sugerimos que as mulheres sejam parte ativa dos esforços de construção da paz  para que esse processo  se torne mais representativo e possa responder também às fontes de insegurança feminina.Palavras-chave: Resolução de conflitos; Construção da paz; Mulheres.ABSTRACTIn this article, we seek to understand the implications of gender relations for the resolution of armed conflicts and the possible contributions resulting from the inclusion of women in peace processes. In the light of feminist theories of International Relations, we propose the hypothesis that one cannot fully understand the dynamics of armed conflict without considering the influence of gender relations for its outbreak and continuity and, therefore, resolution measures that are fully efficient cannot be implemented. Furthermore, we suggest that for the peace process to become more representative and to respond to sources of female insecurity as well.Keywords: Conflict resolution; Peace building; Women. Recebido em: 10/04/2021 | Aceito em: 27/07/2021.
Estabilidade das decisões declaratórias de constitucionalidade: quando e como é cabível a reanálise da (in)constitucionalidade de norma anteriormente declarada inconstitucional
Authors: Scopel Adriano Sayão
Published: December 2021

RESUMO: Abordamos a hipótese de rediscussão pelo Supremo Tribunal Federal de norma anteriormente declarada constitucional em controle abstrato e sua relação com o instituto da coisa julgada, com a conclusão de que há estabilidade nas decisões declaratórias, mas não absoluta, sob pena de petrificar a interpretação constitucional. Defendemos que as regras previstas no CPC/2015 sobre superação de precedentes podem servir de norte para a definição de quando e como deve se dar uma nova análise da (in)constitucionalidade de norma anteriormente declarada constitucional.
Uma reflexão sobre o procedimento especial do mandado de segurança: é possível uma solução dialógica para a melhor concretização de direitos fundamentais ?
Authors: DA SILVA SANDOVAL ALVES , JESUS THIAGO VASCONCELLOS , PINHEIRO VICTOR SALES
Published: December 2021

Há relação entre justiça, argumentação racional e democracia deliberativa. O neoconstitucionalismo e o formalismo valorativo demonstram a importância da tutela efetiva dos direitos fundamentais. Deve-se priorizar soluções definitivas como instrumento de acesso à ordem jurídica justa, com a exposição das argumentações plurais e exercício da persuasão racional. A ação constitucional do mandamus objetiva afastar possíveis atos ilegais, inviabilizada a dilação probatória. Analisou-se a jurisprudência do TJPA sob o ângulo do reconhecimento do formalismo valorativo e quando constatadas eventuais irregularidades processuais no Mandado de Segurança. Concluiu-se sobre fundamentos legais e filosóficos do diálogo para avanço procedimental no MS.
A participação no julgamento de casos repetitivos
Authors: Tavares João Paulo Lordelo
Published: December 2021

O presente artigo tem por objetivo analisar as múltiplas formas de participação no julgamento de casos repetitivos, compreendido como uma espécie de processo coletivo, ao lado das ações coletivas. Para tanto, são utilizados conceitos fundamentais dos processos coletivos, a exemplo das noções de de grupo, membro do grupo e condutor do processo, os quais servirão de ponto de partida para a análise do catálogo legislativo. Ao longo do texto, são propostos meios dinâmicos e atípicos de intervenção, como forma de contornar o problema do déficit participativo. Por outro lado, para que se possa evitar uma indevida dilação processual, é proposta a atribuição de legitimação interventiva ad actum, a partir das circunstâncias do caso concreto.
O confisco alargado no processo penal brasileiro: uma análise de suas normas probatórias
Authors: Cunha Vítor Souza
Published: December 2021

O presente artigo busca analisar a estrutura normativa probatória do confisco alargado no processo penal brasileiro, com especial ênfase na alegação de que ele promove a inversão do ônus da prova em desfavor dos acusados. O trabalho demonstrará que o confisco alargado é baseado em uma presunção legal relativa de ilicitude dos bens incompatíveis de pessoas condenadas por crimes graves. O uso da presunção, como será demonstrado, não implica a inversão do ônus da prova, uma vez que exige do órgão acusador a apresentação de provas idôneas e suficientes para provar os fatos que dão sustentação à presunção.
MITIGAÇÃO DA VOLUNTARIEDADE: UMA ANÁLISE DA VEDAÇÃO DE INTIMAÇÃO JUDICIAL PARA PRÁTICAS RESTAURATIVAS
Authors: Silva Sandoval Alves da , Alves Camille De Azevedo , Siqueira João Renato Rodrigues
Published: December 2021

Aborda-se a vedação da intimação dos envolvidos a participarem de práticas restaurativas, visando analisar a possibilidade de mitigação do princípio da voluntariedade da Justiça Restaurativa, à luz da teoria da jurisdição por substituição. No Judiciário os sujeitos renunciam a vontade individual ou coletiva original, de maneira que o juiz pode intimá-los a participarem de determinados atos judiciais. Conclui-se que, a intimação embora contrarie a vontade individual ou coletiva de participar, está em consonância com a vontade de ser substituído, expressa no ato da demanda, e a vontade geral expressa no ordenamento jurídico de substituir os envolvidos nas demandas.

Intervenção litisconsorcial voluntária: da assistência litisconsorcial ao ingresso mediante a cumulação ulterior de demanda
Authors: Lino Daniela Bermudes , Oliveira Filipe Ramos
Published: December 2021

O artigo propõe uma análise da intervenção litisconsorcial voluntária a partir da cumulação objetiva de demandas e da maior ou menor intensidade de seus vínculos lógicos. Com essas premissas, examinam-se as hipóteses em que o sistema processual permite a cumulação objetiva e subjetiva inicial (art. 113, CPC) para verificar se essas mesmas hipóteses permitem a cumulação ulterior.

LA CONFERENCIA POUND Y LA ADECUACIÓN DEL MÉTODO DE RESOLUCIÓN DE CONFLICTOS
Authors: Muñoz Helena Soleto
Published: December 2021

El artículo pretende aproximar a los fundamentos históricos de la organización de los sistemas de resolución de conflictos en relación con los sistemas procesales de Justicia. Se trata la conferencia Pound de 1976 y su antecedente de 1906 y la importancia en el siglo XXI de las aportaciones del profesor Sander para la integración de los sistemas de resolución adecuados de conflictos en una concepción amplia de los sistemas de Justicia en el siglo XXI. Se aborda la cuestión de la calidad de los sistemas de justicia, señalándose que en los distintos modelos de medición cuantitativa y cualitativa tienen relevancia los métodos adecuados o alternativos de resolución de conflictos, como la mediación, y finalmente se apunta la tendencia a la expansión de los métodos multipuertas, más adecuados y con más calidad, en la resolución de conflictos en los países avanzados.
PERTINENCIA DE LA FORMACIÓN A LOS CAPACITADORES ELECTORALES EN MATERIA DE LOS MÉTODOS DE SOLUCIÓN DE CONFLICTOS PARA GENERAR DE FORMA CREATIVA SOLUCIONES A LOS CONFLICTOS ELECTORALES
Authors: Vera Jéssica Marisol , Espinosa Eni Valdes
Published: December 2021

Las crisis electorales tienen el potencial de causar un daño significativo a la economía nacional y medios de vida individuales; resultar en violencia significativa, desplazamiento y pérdida de propiedad; y en el peor de los casos conducir a una guerra civil o la fragmentación del estado a lo largo líneas étnicas o políticas. Las crisis electorales pueden ser más probables en entornos de transición y en países con líneas de falla basadas en identidad profunda o una historia marcada por disturbios y conflicto. En estas situaciones, se puede recurrir al mediador no solo para facilitar las conversaciones sino también para crear espacios de prevención y capacitación, cómo se desarrollará en este artículo.
