Conflitti politici nella Sardegna tardomedievale
Authors: Soddu Alessandro
Published: January 2021

Non si sono conservati per i contesti comunali della Sardegna i Libri maleficiorum. Tuttavia, il tema del delitto e del conflitto politico, con particolare riguardo ai riflessi nella produzione normativa e nella prassi giudiziaria, può essere osservato esaminando un insieme più eterogeneo di fonti. La seconda metà del Trecento è segnata nell’isola dallo scontro tra il re d’Aragona e il giudice di Arborèa. Due attori che sembrano guardarsi allo specchio perseguendo il medesimo progetto, quello del controllo dell’intera isola e della delegittimazione dell’avversario, celando in questo modo contraddizioni e conflitti interni. È proprio su questi ultimi che il saggio concentra l’attenzione, dal versante meno conosciuto, quello del Giudicato di Arborea, per tentare di fare luce sull’articolato paesaggio politico-sociale dell’ultimo potentato sardo, nel quale l’egemonia della dinastia al potere viene a confliggere con una serie di forze locali, sfociando nel brutale assassinio del giudice Ugone III (1383).
Oligarchi ai margini
Authors: Bitossi Carlo
Published: January 2021

Nell’eta moderna il ceto di governo genovese contava una componente significativa di individui e famiglie di modesta fortuna provenienti da entrambe le antiche fazioni dei populares e dei nobiles. La norma che vietava ai nobili di esercitare arti “meccaniche” ostacolava la risalita sociale dei patrizi decaduti. Alcuni di loro a rischio di declassamento emigrarono dalla città; altri rinunciarono tacitamente all’inclusione nel patriziato; altri, ancora seguitarono a farne parte rimanendone però ai margini. Questi ultimi ricorrevano ai lasciti istituiti dagli esponenti più ricchi delle rispettive casate a beneficio dei consanguinei impoveriti, oppure chiedevano soccorso all’Ufficio dei poveri. Il miglior modo di resistere al declassamento consisteva nell’occupare gli incarichi di governo minori: i comandi nella flotta e nell’esercito, alcune magistrature secondarie in Terraferma e in Corsica. Poiché dall’inizio del Seicento le occasioni di ristabilire le fortune diminuirono, il declassamento finiva col diventare irreversibile. I vertici del ceto di governo si rinnovavano cooptando i nuovi ricchi, che scavalcavano i patrizi di antica data impoveriti. Nonostante un momento di crisi a metà Seicento e un altro a metà Settecento, le provvidenze private e pubbliche e l’occupazione di impieghi pubblici impedirono che il declassamento fomentasse la protesta politica e minacciasse la stabilità del governo oligarchico.
La catégorie de pauvre honteux en débat
Authors: Fontaine Laurence
Published: January 2021

À la fin du XVIIIe siècle, la catégorie de « pauvre honteux » ne va plus de soi. Pour éclairer les tensions qui sont à l’œuvre autour du déclassement des groupes privilégiés, l’article étudie les mémoires écrits à la suite d’un concours lancé par l’académie de Châlons-sur-Marne en 1777 qui appelle à réfléchir « sur les moyens de détruire la mendicité en rendant les mendiants utiles à l’État sans les rendre malheureux. » Des quelques 125 mémoires envoyés, les académiciens ont tiré des extraits à partir desquels l’abbé Malvaux a publié un livre censé reproduire les vues de tous les auteurs. L’article analyse ces essais en partant des définitions qu’ils donnent des pauvres honteux. Il les confronte également avec les commentaires des académiciens et le livre tiré du concours. Ainsi, à côté des textes majoritaires, qui conservent à la catégorie sa référence exclusive aux groupes privilégiés, certains l’étendent à d’autres figures sociales et d’autres la refusent carrément. Ces définitions, qui sous-tendent des projets différents de traitement des pauvres issus des classes privilégiées, portent, avec les définitions élargies, des enjeux de transformation de la société d’ordre.
La condition de cadet dans des temps difficiles : Jacques de Bérulle († 1704), une expérience de reclassement social ?
Authors: Chatelain Claire
Published: January 2021

Les Bérulle ont constitué un lignage un peu particulier de la noblesse de robe du XVIIe siècle. Leur parcours lignager, centré autour d’un de leurs fils puînés, Jacques, au tournant du siècle, fait l’objet de cette étude. Alors que sa formation sociale connaissait des difficultés liées à la dévalorisation des charges, Jacques épousa des professions multiples. À travers les activités de courtage qu’il poursuivait en fait, dont quelques opérations sont présentées ici, il s’agit de comprendre comment se sont articulées les nécessités de l’économie domestique aux possibilités et aux difficultés suscitées par la dynamique d’emprunts de la monarchie en guerre et quels ont été les effets comptables et matériels de cette mutation financière. Jacques de Bérulle apparaît comme un caméléon social nouant des solidarités à partir de champs professionnels tels que celui du monde judiciaire, qui reçoivent une traduction matrimoniale : les alliances qui en résultent ont facilité la pénétration de son lignage par le monde des financiers.
Famiglie che scendono, famiglie che salgono, al tramonto dell’Ancien régime
Authors: Ferrari Maria Luisa
Published: January 2021

Il lavoro ricostruisce in parallelo la condizione di due casati nobili veronesi tra la seconda metà del Settecento e la prima metà dell’Ottocento, in ottica comparativa. Si tratta di due casi opposti. I Malaspina tra difficoltà congiunturali, dissennate politiche speculative e indebitamenti giungono al tracollo. I Dionisi attraverso la diversificazione degli investimenti, l’attenta gestione delle proprietà fondiarie e dei consumi familiari, quadruplicano il patrimonio immobiliare. Il confronto e il contrappunto tra le vicende delle due casate consentono di evidenziare scelte e circostanze capaci di portare all’incremento patrimoniale e all’innalzamento di status all’interno della classe dirigente o al tracollo. Infatti, particolare rilievo assumono le modalità e le scelte degli investimenti, l’amministrazione e la salvaguardia dell’integrità del patrimonio.
Écrit et déclassement
Authors: Deloye Juliette
Published: January 2021

Cet article interroge les liens entre écrit et déclassement. S’intéresser aux pratiques de l’écrit d’un individu permet en effet de complexifier une approche qui mesurerait le déclassement dans l’écart entre ce qui est dit et ce qui est vécu. Pour l’historien, le déclassement est d’abord – et peut-être surtout– écrit, mais la pratique qui consiste à écrire son déclassement gagne encore à être reliée à toutes les autres actions (y compris d’écriture) d’un individu. Qu’est-ce qu’écrire son déclassement et qu’est-ce qu’écrire en situation de déclassement, a fortiori quand on exerce une fonction, celle de secrétaire, qui consiste à écrire ? Pour esquisser des éléments de réponses, cet article est fondé sur une étude de cas qui touche le milieu diplomatique français en Italie en 1803. Elle prend la forme d’une comparaison entre un écrivain célèbre alors secrétaire d’ambassade à Rome, Chateaubriand, et un inconnu simultanément secrétaire particulier d’ambassadeur à Naples, Louis Beer.
Nobles français dans la spirale du déclassement (1780-1860)
Authors: Brelot Claude-Isabelle
Published: January 2021

Dans les rangs de la noblesse provinciale française, le déclassement affecte une minorité, environ 10%. La prosopographie des lignages de la noblesse de Franche-Comté a été dressée pour mesurer et décrire le processus de déclassement. Ses causes sont multiples et conjuguées : pertes révolutionnaires, moins décisives qu’on ne l’a dit ; précarité des noblesse récentes et déficits culturels ; déficit éducatif des enfants et des jeunes gens ; existence débridée et ostentatoire des grands seigneurs ; libertinage enfin. Parfois, le processus de déclassement est rapide, en une génération, et il affecte la totalité du lignage. La spirale du déclassement est infernale pour cette minorité qui a perdu son statut. Plus fréquemment, le déclassement est individuel et momentané, si bien que le reclassement dans la noblesse est possible. Dans la société post-révolutionnaire, la noblesse apparaît comme une nébuleuse aux contours poreux, mouvants et instables.
Characterization of pediatric head and neck masses with quantitative analysis of diffusion-weighted imaging and measurement of apparent diffusion coefficients
Authors: Baiomy Ali , Nada Ayman , Gabr Ahmed , Youssef Ayda , Mahmoud Esmat , Zaky Iman
Published: January 2021

Purpose: Our objective was to investigate the accuracy of quantitative diffusion-weighted imaging (DWI) to determine the histopathologic diagnosis of pediatric head and neck lesions. Materials and Methods: This retrospective study included 100 pediatric patients recently diagnosed with head and neck tumors. All patients underwent preoperative conventional magnetic resonance imaging (MRI) and DWI. Each lesion was evaluated according to signal characteristics, enhancement pattern, and diffusivity. The average apparent diffusion coefficient (ADC) obtained from each tumor was compared to the histological diagnosis of benign, locally malignant, or malignant categories. Results: Our retrospective study showed a significant negative correlation between average ADC and tumor histopathologic diagnosis (P < 0.001, r = -0.54). The mean ADC values of benign, locally malignant lesions, and malignant tumors were 1.65 ± 0.58 × 10−3, 1.43 ± 0.17 × 10−3, and 0.83 ± 0.23 × 10−3 mm2 s−1, respectively. The ADC values of benign and locally malignant lesions were overlapped. We found a cut-off value of ≥1.19 × 10–3 mm2s−1 to differentiate benign from malignant pediatric head and neck masses with a sensitivity of 97.3’, specificity of 80.0’, positive predictive value of 94.7’, and negative predictive value of 88.9’. Conclusion: Diffusion-weighted MRI study is an accurate, fast, noninvasive, and nonenhanced technique that can be used to characterize head and neck lesions. DWI helps to differentiate malignant from benign lesions based on calculated ADC values. Additionally, DWI is helpful to guide biopsy target sites and decrease the rate of unnecessary invasive procedures.

Where there is pancreatic juice, there is a way: Spontaneous fistulization of severe acute pancreatitis-associated collection into urinary bladder
Authors: Aswani Yashant , Ansari Shehbaz MS , Chakraborty Ulhaas S , Hira Priya , Ghosh Sudeshna
Published: January 2021

Pancreatic fluid collections (PFC) are notorious for their extension beyond the normal confines of the pancreatic bed. This distribution is explained by dissection along the fascial planes in retroperitoneum due to the digestive enzymes within the PFC. In genitourinary track, PFCs have been described to involve the kidneys and the ureters. We report a case of severe acute necrotizing pancreatitis in a 28-year-old male, chronic alcoholic, who on readmission developed features of cystitis. The urine was turbid but did not show significant bacteriuria. Close location of the PFC near the urinary bladder (UB) prompted evaluation of urinary lipase and amylase. Elevated urinary enzyme levels suggested a Pancreatico-vesical fistula, conclusive demonstration of which was established by CT cystography. Percutaneous drainage of the necrosum and stenting of pancreatic duct led to spontaneous healing of the pancreatico-vesical fistula. Our case reiterates the remarkable property of pancreatic enzymes to dissect the fascial planes which is demonstrated by decompression of PFC via UB causing spontaneous Pancreatico-vesical fistula. Further, presence of main pancreatic duct fistulization should prompt endoscopic-guided stenting to obliterate the communication with the fistula and accelerate healing.
Subproducts of small residue classes
Authors: Martin Greg , Parvardi Amir
Published: January 2021

For any prime
p, let
$y(p)$
denote the smallest integer y such that every reduced residue class (mod p) is represented by the product of some subset of

$\{1,\dots ,y\}$
. It is easy to see that

$y(p)$
is at least as large as the smallest quadratic nonresidue (mod p); we prove that

$y(p) \ll _\varepsilon p^{1/(4 \sqrt e)+\varepsilon }$
, thus strengthening Burgess’ classical result. This result is of intermediate strength between two other results, namely Burthe’s proof that the multiplicative group (mod p) is generated by the integers up to

$O_\varepsilon (p^{1/(4 \sqrt e)+\varepsilon })$
, and Munsch and Shparlinski’s result that every reduced residue class (mod p) is represented by the product of some subset of the primes up to

$O_\varepsilon (p^{1/(4 \sqrt e)+\varepsilon })$
. Unlike the latter result, our proof is elementary and similar in structure to Burgess’ proof for the least quadratic nonresidue.
Socioeconomic disparities in Korea by health insurance type during the COVID-19 pandemic: a nationwide study
Authors: Jeong Han Eol , Lee Jongseong , Shin Hyun Joon , Shin Ju-Young
Published: January 2021

OBJECTIVES: This study explored socioeconomic disparities in Korea using health insurance type as a proxy during the ongoing coronavirus disease 2019 (COVID-19) pandemic.METHODS: We conducted a retrospective cohort study using Korea’s nationwide healthcare database, which contained all individuals who received a diagnostic test for COVID-19 (n=232,390) as of May 15, 2020. We classified our cohort by health insurance type into beneficiaries of the National Health Insurance (NHI) or Medicaid programs. Our study outcomes were infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and COVID-19-related outcomes, a composite of all-cause death, intensive care unit admission, and mechanical ventilation use. We estimated age-, sex-, and Charlson comorbidity index score–adjusted odds ratios (aORs) with 95% confidence intervals (CIs) using a multivariable logistic regression analysis.RESULTS: Of the 218,070 NHI and 14,320 Medicaid beneficiaries who received COVID-19 tests, 7,777 and 738 tested positive, respectively. The Medicaid beneficiaries were older (mean age, 57.5 vs. 47.8 years), more likely to be males (47.2 vs. 40.2%), and had a higher comorbidity burden (mean CCI, 2.0 vs. 1.7) than NHI beneficiaries. Compared to NHI beneficiaries, Medicaid beneficiaries had a 22% increased risk of SARS-CoV-2 infection (aOR, 1.22; 95% CI, 1.09 to 1.38), but had no significantly elevated risk of COVID-19-related outcomes (aOR 1.10, 95% CI 0.77 to 1.57); the individual events of the composite outcome yielded similar findings.CONCLUSIONS: As socioeconomic factors, with health insurance as a proxy, could serve as determinants during the current pandemic, pre-emptive support is needed for high-risk groups to slow its spread.

Authors: Onufer Emily J. , Andrade Erin G. , DeClue Angelia , Bochicchio Grant , Wise Paul , Klingensmith Mary E. , Eaton Stephen , Kirby John , Punch L. J.
Published: January 2021

Background

While wound management is a common task for practicing surgeons, there is a paucity of dedicated education on soft tissue management during residency training.

Objective

The COVER (Causes of soft tissue injury, Obstacles to closure, Vacuums and stitches, Epithelialization, Rationale for wound care) curriculum was developed to engage junior surgery residents in the management of soft tissue injury and infection.

Methods

Junior surgery residents participated in the COVER lab during academic years 2018–2020. Residents applied appropriate surgical management and wound care to cadaveric models of soft tissue injury and infection. Assessments included a pre-/post-curriculum and pre-/post-lab multiple choice questionnaire and survey.

Results

All eligible residents (n = 45, 27) participated in the COVER lab for both academic years. Postgraduate year (PGY)-1s, PGY-2s, and PGY-3s showed improvement in wound management knowledge with an average increase in score of 17%, 8%, and 18%, respectively. They also showed a change in their self-reported perceived ability to achieve primary soft tissue closure with confidence levels 22%, 20%, and 16%, respectively. This was again seen in perceived ability to manage soft tissue injuries and infections (28%, 28%, and 23%, respectively). There was a significant increase in performing new wound management skills (PGY-1 mean 51.3%, PGY-2 33.5%, PGY-3 20%; ANOVA, P = .0001).

Conclusions

The COVER curriculum provides a systematic approach to soft tissue injury and infection. Residents showed a significant increase in both soft tissue knowledge as well as confidence in ability to perform wound management.
Universal Well-Being Assessment Associated With Increased Resident Utilization of Mental Health Resources and Decrease in Professionalism Breaches
Authors: Sofka Sarah , Lerfald Nathan , Reece Josephine , Davisson Laura , Howsare Janie , Thompson Jesse
Published: January 2021

Background

A previous study showed that residents felt a universal well-being visit to a Faculty Staff Assistance Program (FSAP) would increase self-initiated visits. It is unknown whether such program is associated with more self-initiated visits, improved professionalism, or positive well-being measures.

Objective

We measured internal medicine (IM) resident-initiated visits before and after the universal well-being FSAP intervention to assess for increased utilization of FSAP services and effect on professionalism and well-being measures.

Methods

Universally scheduled, resident-initiated, program-mandated FSAP visits for IM residents at West Virginia University were counted for years 2014–2019. Professionalism reports of all residents and IM residents were tallied. A Mann-Kendall trend test was used to estimate slope of trends. Burnout and compassion satisfaction (CS) scores were assessed from 2017–2020.

Results

Residents opted-out of 8 of 239 (3.3%) universally scheduled FSAP visits. Resident-initiated visits significantly increased from 0 in 2014–2015 to 23 in 2018–2019 (slope = 6.5; P = .027; 95% CI [1.0, 8.0]). Program-mandated visits significantly decreased from 12 in 2014–2015 to 3 in 2018–2019 (slope = -2.4; P = .027; 95% CI [-3.0, -1.0]). IM-attributed professionalism reports significantly decreased from 17 of 62 (31%) in 2014 to 1 of 62 (1.6%) in 2019 (slope = -5.7%; P = .024; 95% CI [-11.6%, -0.6%]). Burnout scores remained in the low range (≤ 22) and CS scores in the average-high range (38.7–42) from 2017–2020.

Conclusions

A universal well-being FSAP program increased resident utilization of mental health resources and was associated with fewer professionalism breaches.
The Carbon Footprint of Residency Interview Travel
Authors: Donahue Laura M. , Morgan Helen K. , Peterson William J. , Williams John A.
Published: January 2021

Background

Over the last decade, medical student residency applicants have shown a substantial increase in the number of interviews attended, which is associated with a significant increase in travel. The carbon footprint associated with residency interviews has not been well documented prior to this investigation, and is a critical issue related to climate health.

Objective

The purpose of this study is to document the carbon footprint associated with travel to residency interviews of the applicants from a single institution.

Methods

Graduating medical students from the University of Michigan Medical School were surveyed in 2020 to gather information regarding travel related to residency interviews. A validated carbon emissions calculator was used to determine the associated carbon footprint.

Results

Response rate was 103 of 174 (59%). Average interviews per student across all specialties was 14.39 interviews per student. The overall class average for total carbon footprint per student was calculated as 3.07 metric tons CO2, making the class average carbon footprint per interview 0.21 metric tons CO2. If we extrapolate the results of our study to all residents, the resulting CO2 emissions approach 51 665 metric tons CO2 per year, which is equivalent to the amount of CO2 produced by 11 162 passenger cars in 1 year.

Conclusions

Medical education leaders could help reduce the carbon footprint by encouraging a reduction in number of in-person interviews attended by applicants.

Authors: CHÍN NGÔ , THUẤN NGUYỄN
Published: January 2021

With the continuous effort of the Vietnamese Goverment, there is much research on restructuring State-owned Enterprises (SOE) to establish the State-capital Enterprises (SCE). However, there are few studies on combining intangible resources such as social capital, entrepreneurship despite these resources increase indirectly tangible resources. This study, therefore, tries to build a research model describing (i) the impact of the above resources on SCE performance (ii) the relationship among social capital and performance via entrepreneurship. After adjusting the measurement scales by interviewing specialist in-depth, a quantitative survey was executed using the data collected from 568 SCE and by testing Cronbach’s Alpha reliability, EFA, CFA and SEM to comment three proposed hypotheses. The results showed that (i) both social capital and entrepreneurship had positive impacts on performance (ii) social capital had positive impact indirectly on performance through entrepreneurship. Accordingly, the study suggested some practical implications for managers to use properly resources.

Authors: Wang Jun , Chen Zhan
Published: January 2021

The data mining technology of the K-means algorithm combined with BIM (Building Information Modeling) technology is applied to management engineering, which is convenient for project management personnel. Method: The K-means clustering algorithm is combined with the support vector machine algorithm. The support vector machine is used to ensure the high accuracy of the anomaly detection algorithm. The K-means clustering algorithm is used to divide the support vector machine into blocks. It also analyzes the different needs of the facility management staff, and clearly defines the content and level of detail required to build the BIM model. It not only meets the data requirements for operation and maintenance but also avoids waste caused by excessive modeling. Result: Compared with traditional support vector machines, the improved algorithm in this paper has a higher detection rate and lower false alarm rate. Also, it can shorten the detection time of large-scale data to provide an effective method for abnormal detection of sensor networks and processing of large-scale data sets. The improved method increases the detection accuracy by 8.13% and decreases the false alarm rate by 89.08%. In terms of detection time, the improved method increases by 3.82s, which is 4.67 times the traditional method. Conclusion: The structural health monitoring system can efficiently and accurately monitor the accuracy of the data. BIM can provide rich operation and maintenance data for facility management to effectively improve the efficiency of facility management.

Big Data Techniques for Clinical Image Analysis
Authors: Ying Hang , Yu Qin
Published: January 2021

The process of extracting clinical images, for instance, heart images from cameras is full of noises and complexities. As such, the general expenditure for processing these images like resources and time is significantly high, mostly for complex and large amounts of data. In that case, this research contribution utilizes the machine vision-centred method to effectively address these issues. The method significantly incorporates four essential stages with various forms of algorithms to handle the clinical heart images. In the first stage, the smoothing algorithm is utilized to minimize some form of noise. In the second stage, the filtering algorithms are applied for the analysis of images to effectively identify the targeted region. In the third stage, more developed algorithm is utilized to evaluate the image characteristics in the targeted region, identifying the basic image outline. Lastly, the reduction algorithm is meant to transform the original image into significantly precise and smooth pictures. The experimental findings indicate that the machine vision-centred clinical image analysis algorithm might significantly extract fundamental data and attain the most reliable results, contrasting with the most ancient image analysis techniques.

Authors: Trenevska Blagoeva Kalina , Mijoska Belsoska Marina , Trpkova-Nestorovska Marija
Published: January 2021

Followed by the mobile technology development and high rate of mobile internet usage worldwide, mobile banking has become prominent technological innovation in the banking sector giving a competitive edge over traditional banking. Smartphones and mobile technologies are becoming increasingly available and affordable in North Macedonia in recent years, and many banks are providing banking services to customers via smartphones. The adoption of mobile banking in the country has not reached its full potential yet and has been at its early stage of adoption. However, not many studies investigate determinants of mobile banking adoption which may help banks to design more suitable mobile services for customers and increase the m-banking adoption in the country. This study is the first attempt to fill this gap by examining determinants that affect consumer intention to use mobile banking services in the country, as developing country. To get insights regarding the user adoption of m-banking services in the country, a survey was conducted among more than 150 mobile users. This study proposes a mobile banking user adoption research model based on the Technology Acceptance Model (TAM), and beside basic constructs (perceived ease of use, perceived usefulness and behavioral intention to use) it integrates social image, trust and risk that are specific for mbanking. The results of the empirical study are supporting the proposed basic constructs of the model and some specific relationships are unveiled. This research is a holistic approach representing a solid base for future studies on the adoption of new technologies in the country. Its originality and practical implications are reflected in determining the significance of additional constructs that are specific for m-banking. From practitioner’s viewpoint, this research offers valuable insights for developing m-banking solutions.
MEASURING THE EFFECT OF SALARY RAISE OVER THE PERFORMANCE OF SALES PROFESSIONALS – THE CASE OF AN INTERNATIONAL ORGANIZATION
Authors: Dimovska Nena , Eftimov Ljupcho
Published: January 2021

Should fixed salary be the single and most appropriate tool for motivating employees; or should management consider a more diverse, innovative tools for motivation, based on multiple factors? Does a salary increase always guarantee ROI? Also, will sales professionals be motivated by an incremental, equal-to-all salary increase? This paper elaborates these and similar dilemmas and presents a research conducted in the sales sector, in a medium-sized international firm. It represents consequences of applying an equal and applicable to all salary increase of 10%. Тhe paper tries to reject traditional beliefs (and awards distribution models) that salary, per se, is the highest source or motivation and a guarantee for improving performance. Тhe research shows how sales professionals are affected by incremental salary increase, and tries to provide recommendations for further research on effective, cost-efficient award strategies that increase motivation and performance and can be easily adopted in similar organizations.
INCENTIVES FOR SOCIAL MEDIA USERS’ ENGAGEMENT TO DIFFERENT BRAND-RELATED CONTENT TYPES
Authors: Palamidovska-Sterjadovska Nikolina , Ciunova-Shuleska Anita
Published: January 2021

The purpose of this study is to analyze social media users’ incentives for engagement with brand-related content on social media. Based on the uses and gratification theory, two types of incentives are analyzed as motivators of users’ brand engagement, i.e. communal and self-interest incentives. Users’ brand engagement is conceptualized and measured as intentions to contribute to brand-related content on social media in terms of intentions for commenting, sharing, and liking. Further, it is assumed that the effects of the two types of incentives (communal and self-interest) vary depending on the brand-related content type (commercial messages, personal opinions and lifestyle affairs). An online survey was conducted for obtaining quantitative data which were analyzed by applying structural equation modeling. The total number of effective responses is 415. The results indicate that only communal incentives motivate users to contribute to brand-related commercial messages, personal opinions and lifestyle affairs. The obtained results could be utilized by brand marketers in effectively designing brand-related content on social media.

Published: January 2021

Modern business conditions impose the need for more precise measurement of companies' marketing performance. Quantitative knowledge, which are necessary for decision makers are partially obtained based on the results of marketing metrics which greatly facilitate the decision-making process. Thus, the subject of the research in this paper is the degree of knowledge and application of marketing metrics in Montenegrin companies, but also the importance that managers give to them when making business decisions. The research was conducted on a sample of 65 companies which operate in Montenegro, and it included a set of financial and non-financial marketing metrics. The results show that managers in Montenegro are pretty familiar with marketing metrics and consider them important for business decision making. However, the level of their implementation is not at a satisfactory one due to the lack of specific knowledge required for their adequate application.

Purpose: The Purpose of the study was to explore the management practices that govern students’ residential affairs that enable the pursuit of educational goals in Makerere University. The research objective that guided the study was how management practices regarding residential affairs enabled or disabled on-campus and off-campus students to pursue their educational goals.

Methodology: Cushioned by the social justice literature we inquired on how Makerere University managed students’ residential affairs and how such management practices supported the students to achieve their educational goals. We adopted a qualitative approach informed by comparative phenomenological design. A purposive sampling technique was used to obtain 8 informants drawn from the science and humanities schools. Data was analysed qualitatively using thematic analysis.

Findings: The study found out that management practices such as allocation and flexibility regarding residential affairs enabled pursuit of educational goals. However, absence of regular supervision contributed to poorly maintained halls of residence, toilets and bathrooms are filthy, dilapidated rooms, poor security and meals. These acted as barriers in the way the students pursued their educational goals.  

Contribution to theory, practice and policy: the findings and discussion will contribute to the knowledge required for managing students’ residential affairs for Makerere University and other higher learning institutions through formulation and implementation responsive strategies for convenience that enable students to accomplish their educational goals.

EFFICIENT PROBE STATION PLACEMENT AND PROBE SET SELECTION FOR FAULT LOCALIZATION
Authors: KINGER SHAKTI , PATIL B.M.
Published: January 2021

Network fault management has been a focus of research activity with more emphasis on fault localization – zero down exact source of a failure from set of observed failures. Fault diagnosis is a central aspect of network fault management. Since faults are unavoidable in communication systems, their quick detection and isolation is essential for the robustness, reliability, and accessibility of a system. Probing technique for fault localization involves placement of probe stations (Probe stations are specially instrumented nodes from where probes can be sent to monitor the network) which affects the diagnosis capability of the probes sent by the probe stations. Probe station locations affect probing efficiency, monitoring capability, and deployment cost. We present probe station selection algorithms and aim to minimize the number of probe stations and make the monitoring robust against failures in a deterministic as well as a non-deterministic environment. We then implement algorithms that exploit interactions between probe paths to find a small collection of probes that can be used to locate faults. Small probe sets are desirable in order to minimize the costs imposed by probing, such as additional network load and data management requirements. We discuss a novel integrated approach of probe station and probe set selection for fault localization. A better placing of probe stations would produce fewer probes and probe set maintaining same diagnostic power. We provide experimental evaluation of the proposed algorithms through simulation results.
ATTACK AGAINST ANONYMITY USING CELL COUNTING
Authors: HABEEBUNNISA S. D. , KARIMULLAH S. K. , BABU P.
Published: January 2021

Various low-latency anonymous communication systems such as Tor and Anonymizer have been designed to provide anonymity service for users. In order to hide the communication of users, most of the anonymity systems pack the application data into equal-sized cells. Via extensive experiments on Tor, we found that the size of IP packets in the Tor network can be very dynamic because a cell is an application concept and the IP layer may repack cells. Based on this finding, we investigate a new cell-counting-based attack against Tor, which allows the attacker to confirm anonymous communication relationship among users very quickly. In this attack, by marginally varying the number of cells in the target traffic at the malicious exit onion router, the attacker can embed a secret signal into the variation of cell counter of the target traffic. The embedded signal will be carried along with the target traffic and arrive at the malicious entry onion router. Then, an accomplice of the attacker at themalicious entry onion router will detect the embedded signal based on the received cells and confirm the communication relationship among users. We have implemented this attack against Tor, and our experimental data validate its feasibility and effectiveness. There are several unique features of this attack. First, this attack is highly efficient and can confirm very short communication sessions with only tens of cells. Second, this attack is effective, and its detection rate approaches 100% with a very low false positive rate. Third, it is possible to implement the attack in a way that appears to be very difficult for honest participants to detect.
SMC PROTOCOL FOR DISTRIBUTED K- ANONYMITY
Authors: SIREESHA V. , OBULESU B.
Published: January 2021

Secure multiparty protocols have been proposed to enable non colluding parties to cooperate without a trusted server. Even though such protocols put off information exposé other than the objective function, they are quite costly in computation and communication. The high overhead motivates parties to estimate the utility that can be achieved as a result of the protocol beforehand. To avoid this issue we propose a look-ahead approach, specifically for secure multiparty protocols to achieve distributed k-anonymity, which helps parties to decide if the utility benefit from the protocol is within an acceptable range before initiating the protocol. The look-aheadoperation is highly localized and its accuracy depends on the amount of information the parties are willing toshare. Experimental results show the effectiveness of the proposed methods.

Published: January 2021

Microstrip printed wide slot antenna with a fork like tuning stub for bandwidth enhancement is proposed in this paper. By applying fork like tuning stub to the microstrip wide slot antenna instead of line feed, it is experimentally found that operating bandwidth can be enhanced. Experimental results indicate that the impedance bandwidth, defined by -10dB return loss, of the proposed wide slot antenna can reach operating bandwidth of 3.1 GHz at operating frequency about 2 GHz which is 6 times greater than conventional wide slot antenna.
