The Arab Uprising—Comparing Jasmine’s success to Rage’s failure

V Tuniziji so proti koncu 2010 zanetili iskro Arabske vstaje in njen ogenj se je razširil po celotni regiji in postal problem severne Afrike in Bližnjega vzhoda. Domino efekt je pahnil dežele v razmere zmede in nemirov. Teza se poslužuje metode primerjalnega pristopa tekom katere primerjam dve vidni državi v regiji. Tunizija, kjer se je iskra upora prižgala, je stopala naprej po poti demokratizacije.Na drugi strani je Egipt, močna arabska država, kljub temu da ni bil potegnjen v državljansko vojno, zabredel v blato avtoritarizma. Dva bistvena akterja, ki sta vplivala na razvoj dogodkov v obeh državah sta bila vojska in Islamske stranke.Vojska je usmerjala tok vstaje tako, da se je postavila v bran ali pa proti koristim ljudstva.V deželah močno prisotne Islamske stranke so vplivale na dogodke tako, da so odprle pot dijaloga in možnosti sekularnega razvoja ali pa ne. Oba akterja, s svojimi podedovanimi predstavami o prihodnosti in idejologijami kako vladati, sta vodila vsako od omenjenih držav po njeni lastni drugačni poti. K sreči je Tunizija s svojo Revolucijo jasmina dobila možnost, da se odtrga od diktature. Na drugi strani so okoliščine, ki so na žalost obdajale egiptovsko Revolucijo jeze, potisnile deželo v kremplje avtoritarizma.The Arab Uprising has been an issue of Middle East and North Africa (MENA) since the late 2010, when its spark got ignited in Tunisia. The domino effect spread in the region dragging countries into a state of restlessness and confusion. The thesis follows a comparative approach in which two outstanding countries in the region are compared: Tunisia as the initiator of the spark and the leader country in its path to democratization, and Egypt as a powerful Arab country which, despite not falling into civil war, was still being dragged in the mud of authoritarianism. Two major factors that contributed to the process of events taking place in the two countries were the military and Islamic parties. The military had its effect on the revolution while siding with or against the benefit of the nationthe Islamic parties of stronger presence in the country also had their effect on the process of events in either opening or not opening the path for dialogue and secular development in the country. Both agents with their inherited perspectives and ideologies on the way of ruling led each of the mentioned countries to its own different path. Luckily, with the Jasmine Revolution, Tunisia was given the chance to tear away from the dictatorshipbut unluckily for Egypt, the circumstances surrounding Rage Revolution pushed the country further into the claws of authoritarianism

Juvenile pleomorphic adenoma of the cheek: a case report and review of literature

Pleomorphic adenoma, also called benign mixed tumor, is the most common tumor of the salivary glands. About 90% of these tumors occur in the parotid gland and 10% in the minor salivary glands. The most common sites of pleomorphic adenoma of the minor salivary glands are the palates followed by lips and cheeks. Other rare sites include the throat, floor of the mouth, tongue, tonsil, pharynx, retromolar area and nasal cavity. In children, intraoral pleomorphic adenomas of the cheek are extremely rare with only three cases reported to date. Here we report a case of pleomorphic adenoma of minor salivary glands of the cheek in a 17-year-old girl. The mass was removed by wide local excision with adequate margins, and after a follow-up period of three years there were no recurrences. To conclude, pleomorphic adenoma should be considered in the differential diagnosis of cheek masses in youngsters. Wide local excision is to be recommended as the treatment of choice. A close follow-up is necessary postoperatively

Interface Recombination of The Heterojunction Solar Cells

  In this work, we study density of active interface states Nir between window layer CdS and absorber layer CdTe of heterojunction solar cell CdS/CdTe. The effect of this density on the parameters of solar cell was also explained. Interface state is the result of lattice mismatch of two materials used. Here, we regard interface states as impurity level. In order to understand the behavior of these cells a theoretical model has been developed for pn heterojunction solar cells in which interface recombination between CdS and CdTe is the dominant mechanism of current transport for these cells. The model explains the large junction ideality factor (n>1) and the increased saturation current density in terms of increased density of active interface states Nir .The interface recombination leads to lower values of the open circuit voltage Voc , short circuit current Isc , and fill factor FF. These results are illustrated by numerical calculation of solar cell parameters CdS/CdTe

Biased Recognition of Facial Affect in Patients with Major Depressive Disorder Reflects Clinical State

Cognitive theories of depression posit that perception is negatively biased in depressive disorder. Previous studies have provided empirical evidence for this notion, but left open the question whether the negative perceptual bias reflects a stable trait or the current depressive state. Here we investigated the stability of negatively biased perception over time. Emotion perception was examined in patients with major depressive disorder (MDD) and healthy control participants in two experiments. In the first experiment subjective biases in the recognition of facial emotional expressions were assessed. Participants were presented with faces that were morphed between sad and neutral and happy expressions and had to decide whether the face was sad or happy. The second experiment assessed automatic emotion processing by measuring the potency of emotional faces to gain access to awareness using interocular suppression. A follow-up investigation using the same tests was performed three months later. In the emotion recognition task, patients with major depression showed a shift in the criterion for the differentiation between sad and happy faces: In comparison to healthy controls, patients with MDD required a greater intensity of the happy expression to recognize a face as happy. After three months, this negative perceptual bias was reduced in comparison to the control group. The reduction in negative perceptual bias correlated with the reduction of depressive symptoms. In contrast to previous work, we found no evidence for preferential access to awareness of sad vs. happy faces. Taken together, our results indicate that MDD-related perceptual biases in emotion recognition reflect the current clinical state rather than a stable depressive trait

The effect of leader trust and knowledge sharing on staff satisfaction at work: investigation of universities in Syria

This research paper examines the effect of leader trust, organisational trust and knowledge sharing on staff attitudes and satisfaction at work at universities in Syria. The research methodology employs a quantitative design of questionnaire instrument. The model predicts that if employees develop high levels of trust in their leader and organizations, this will stimulate a good quality relationship and develop satisfaction at work. Leader trust, Knowledge sharing behaviour and job satisfaction subscales are based on prior research measures. Sampling strategy employed non-probability sampling. The size of the sample is 161. The results of the research designate that trust in leader and knowledge sharing behaviours are positively associated with employee job satisfaction

Management of Infective Endocarditis in Pregnancy by a Multidisciplinary Team: A Case Series

Introduction: The incidence of infective endocarditis (IE) in pregnancy is rare and has been increasing during the opioid epidemic. IE in pregnancy is associated with high rates of maternal and fetal morbidity and mortality. Multidisciplinary endocarditis teams for management of IE have been shown to reduce in-hospital and 1-year mortality. We present a single-center experience managing IE in pregnancy utilizing a multidisciplinary endocarditis team. Methods: Patients diagnosed with IE while pregnant or within 30 days post-partum were identified. All patients discussed at the institution\u27s weekly multidisciplinary endocarditis meeting were included. Demographic and clinical data and outcome-related variables were retrospectively reviewed and recorded. Results: Between 1 October 2020 and 1 June 2021 6 pregnant or 30-day post-partum patients with IE were identified. All patients had co-morbid injection drug use; Staphylococcus aureus was the etiologic pathogen in all patients. All patients had embolic complications and 5 required ICU admission and mechanical ventilatory support. Four patients underwent valve replacement. There were no patient-directed discharges. All patients survived to hospital discharge and 90-days after diagnosis. Four pregnancies resulted in delivery at an average gestational age of 32.4 weeks with 3 requiring NICU admissions and prolonged lengths of stay. All patients were seen by addiction medicine and 5 were started on medication-assisted treatment for opioid use disorder. Discussion: In a small retrospective cases series, coordination of care by a multidisciplinary endocarditis team led to a high-rate of surgical intervention with no patient-directed discharges and no in-hospital or 90-day mortality. Conclusion: Multidisciplinary endocarditis teams are a low-risk intervention that may improve outcomes in pregnant patients with IE

A Step-by-Step Guide to Implementing a Multidisciplinary Endocarditis Team

Over the last several years multiple studies, primarily from European centers have demonstrated the clinical and outcomes benefits of multidisciplinary endocarditis teams. Despite this literature, adoption of this approach to patient care has been slower in the United States. While there is literature outlining the optimal composition of an endocarditis team, there is little information to guide providers as they attempt to transform practice from a fragmented, disjointed process to an efficient, collaborative care model. In this review, the authors will outline the steps they took to create and implement a successful multidisciplinary endocarditis team at the University of Michigan. In conjunction with existing data, this piece can be used as a resource for clinicians seeking to improve the care of patients with endocarditis at their institutions

Occurrence of vancomycin-resistant Staphylococcus aureus in the oral cavity of patients with dental caries

Oral streptococci are the major group of microbes isolated from oral microflora. They represent frequent pathogens of infective endocarditis (IE), and it is assumed that in most of the cases oral streptococci are acquired via mucosa layer of oral cavity. Staphylococcus aureus is also frequently isolated from IE as it accounts for 20%–30% of all cases. Vancomycin has been the most reliable therapeutic agent against infections caused by methicillin-resistant S. aureus (MRSA). The main objective of this study was to examine the occurrence of S. aureus species in dental caries specimens. Antimicrobial susceptibility testing of S. aureus to four antibiotics namely vancomycin, linezolid, teicoplanin, and daptomycin was performed. Detection of vancomycin resistance was conducted using polymerase chain reaction. Among the tested 150 strains, 98 were MRSA and of that 54 were vancomycin sensitive and 27 were resistant. All 98 MRSA strains were positive for mecA and 36 yielded pvl, whereas 13 carried vanA and only 2 were positive for vanB. Majority of the isolates showed sensitivity toward daptomycin and linezolid. Strains of S. aureus exhibiting decreased susceptibility to different antibiotics like vancomycin, daptomycin, and linezolid severely compromise the therapeutic alternatives and require a considerable amount of time, public awareness, and integrative health-care strategies to prevent the emergence of resistance to these compounds

An invasive adenocarcinoma of the accessory parotid gland: a rare example developing from a low-grade cribriform cystadenocarcinoma?

Low-grade cribriform cystadenocarcinoma (LGCCA) is a rare tumor of the salivary gland that exhibits clinically indolent behavior. In this paper, we present a case of invasive adenocarcinoma of the accessory parotid gland in a young male that exhibited histology suggestive of an association of LGCCA. A 27-year-old man presented with a subcutaneous tumor in his left cheek. The tumor was separated from the parotid gland and located on the masseter muscle. The tumor was resected, and the postoperative histological diagnosis was adenocarcinoma, not otherwise specified (ANOS). The tumor exhibited papillary-cystic and cribriform proliferation of the duct epithelium and obvious stromal infiltration. Some tumor nests were rimmed by myoepithelium positive for smooth muscle actin, p63, and cytokeratin 14, indicating the presence of intraductal components of the tumor. Tumor cells exhibited mild nuclear atypia, and some of them presented an apocrine-like appearance and had cytoplasmic PAS-positive/diastase-resistant granules and hemosiderin. Other cells had foamy cytoplasm with microvacuoles. Immunohistochemistry revealed that the almost all of the tumor cells were strongly positive for S-100. These histological findings suggest the possibility that ANOS might arise secondarily from LGCCA. This is an interesting case regarding the association between ANOS and LGCCA in oncogenesis
