The role of classroom management in the formation of teachers’ well-being
Abstract. Teacher well-being is essential not just for teachers themselves, but for every stakeholder in shools. If teachers experience their job positively and are satisfied with it, they will perform their day-to-day tasks better, will be less likely to leave the profession, and their students will be more likely to succeed academically. Given this tremendous importance of teacher well- being, understanding how it can be promoted is crucial for every stakeholder.
While there are many factors that comprise teacher well-being, this thesis will show that how teachers deal with classroom management is of primary significance to the formation of their well-being. If teachers can utilize effective classroom management strategies, they will experience their interactions with students much more positively, their students will perform better academically, and this will create a positive cycle that leads to better outcomes for both teachers and students.
This thesis is a literature review of previous research that was deemed relevant. First, different components and conceptualizations of teacher well-being will be explored. Then, how classroom management and teacher well-being are connected will be examined. Lastly, some effective classroom management strategies will be discussed
Laser annealing of silicon on sapphire
Silicon-implanted silicon-on-sapphire wafers have been annealed by 50-ns pulses from a Q-switched Nd : YAG laser. The samples have been analyzed by channeling and by omega-scan x-ray double diffraction. After irradiation with pulses of a fluence of about 5 J cm^–2 the crystalline quality of the silicon layer is found to be better than in the as-grown state
Coronary-artery bypass surgery in patients with left ventricular dysfunction
The role of coronary-artery bypass grafting (CABG) in the treatment of patients with coronary artery disease and heart failure has not been clearly established.Between July 2002 and May 2007, a total of 1212 patients with an ejection fraction of 35% or less and coronary artery disease amenable to CABG were randomly assigned to medical therapy alone (602 patients) or medical therapy plus CABG (610 patients). The primary outcome was the rate of death from any cause. Major secondary outcomes included the rates of death from cardiovascular causes and of death from any cause or hospitalization for cardiovascular causes.The primary outcome occurred in 244 patients (41%) in the medical-therapy group and 218 (36%) in the CABG group (hazard ratio with CABG, 0.86; 95% confidence interval [CI], 0.72 to 1.04; P=0.12). A total of 201 patients (33%) in the medical-therapy group and 168 (28%) in the CABG group died from an adjudicated cardiovascular cause (hazard ratio with CABG, 0.81; 95% CI, 0.66 to 1.00; P=0.05). Death from any cause or hospitalization for cardiovascular causes occurred in 411 patients (68%) in the medical-therapy group and 351 (58%) in the CABG group (hazard ratio with CABG, 0.74; 95% CI, 0.64 to 0.85; P<0.001). By the end of the follow-up period (median, 56 months), 100 patients in the medical-therapy group (17%) underwent CABG, and 555 patients in the CABG group (91%) underwent CABG.In this randomized trial, there was no significant difference between medical therapy alone and medical therapy plus CABG with respect to the primary end point of death from any cause. Patients assigned to CABG, as compared with those assigned to medical therapy alone, had lower rates of death from cardiovascular causes and of death from any cause or hospitalization for cardiovascular causes.

Myocardial viability and survival in ischemic left ventricular dysfunction
The assessment of myocardial viability has been used to identify patients with coronary artery disease and left ventricular dysfunction in whom coronary-artery bypass grafting (CABG) will provide a survival benefit. However, the efficacy of this approach is uncertain.In a substudy of patients with coronary artery disease and left ventricular dysfunction who were enrolled in a randomized trial of medical therapy with or without CABG, we used single-photon-emission computed tomography (SPECT), dobutamine echocardiography, or both to assess myocardial viability on the basis of prespecified thresholds.Among the 1212 patients enrolled in the randomized trial, 601 underwent assessment of myocardial viability. Of these patients, we randomly assigned 298 to receive medical therapy plus CABG and 303 to receive medical therapy alone. A total of 178 of 487 patients with viable myocardium (37%) and 58 of 114 patients without viable myocardium (51%) died (hazard ratio for death among patients with viable myocardium, 0.64; 95% confidence interval [CI], 0.48 to 0.86; P=0.003). However, after adjustment for other baseline variables, this association with mortality was not significant (P=0.21). There was no significant interaction between viability status and treatment assignment with respect to mortality (P=0.53).The presence of viable myocardium was associated with a greater likelihood of survival in patients with coronary artery disease and left ventricular dysfunction, but this relationship was not significant after adjustment for other baseline variables. The assessment of myocardial viability did not identify patients with a differential survival benefit from CABG, as compared with medical therapy alone.

Coronary-Artery Bypass Surgery in Patients with Ischemic Cardiomyopathy
BACKGROUND: The survival benefit of a strategy of coronary-artery bypass grafting (CABG) added to guideline-directed medical therapy, as compared with medical therapy alone, in patients with coronary artery disease, heart failure, and severe left ventricular systolic dysfunction remains unclear. METHODS: From July 2002 to May 2007, a total of 1212 patients with an ejection fraction of 35% or less and coronary artery disease amenable to CABG were randomly assigned to undergo CABG plus medical therapy (CABG group, 610 patients) or medical therapy alone (medical-therapy group, 602 patients). The primary outcome was death from any cause. Major secondary outcomes included death from cardiovascular causes and death from any cause or hospitalization for cardiovascular causes. The median duration of follow-up, including the current extended-follow-up study, was 9.8 years. RESULTS: A primary outcome event occurred in 359 patients (58.9%) in the CABG group and in 398 patients (66.1%) in the medical-therapy group (hazard ratio with CABG vs. medical therapy, 0.84; 95% confidence interval [CI], 0.73 to 0.97; P=0.02 by log-rank test). A total of 247 patients (40.5%) in the CABG group and 297 patients (49.3%) in the medical-therapy group died from cardiovascular causes (hazard ratio, 0.79; 95% CI, 0.66 to 0.93; P=0.006 by log-rank test). Death from any cause or hospitalization for cardiovascular causes occurred in 467 patients (76.6%) in the CABG group and in 524 patients (87.0%) in the medical-therapy group (hazard ratio, 0.72; 95% CI, 0.64 to 0.82; P<0.001 by log-rank test). CONCLUSIONS: In a cohort of patients with ischemic cardiomyopathy, the rates of death from any cause, death from cardiovascular causes, and death from any cause or hospitalization for cardiovascular causes were significantly lower over 10 years among patients who underwent CABG in addition to receiving medical therapy than among those who received medical therapy alone.

Common Man, Society and Religion in the 16th century/Gemeiner Mann, Gesellschaft und Religion im 16. Jahrhundert
Der zweisprachige Sammelband vereinigt zum Teil bahnbrechende Ergebnisse einer interdisziplinären Forschungstagung, deren Beiträge sozial-, wirtschafts-, kultur- und kirchengeschichtliche Aspekte der Frühneuzeit im Karpatenbogen aufgreifen. Basierend auf vielfach erstmals ausgewerteten Quellen bearbeiten die Beiträge aktuelle Fragestellungen und Forschungshorizonte zur Interdependenz von sozialen, ökonomischen, kulturellen und religiösen Phänomenen im Karpatenbogen der Frühen Neuzeit, in dem die Osmanen der international dominante politische Faktor wurden. Transformationsprozesse wurden angestoßen durch Bevölkerungs- und Militärbewegungen, ökonomische, politische und religiös-mentale Umwälzungen, die zwischen opportunistischer Anpassung und rebellierendem Widerstand oszillierten und entsprechende politische Maßnahmen und Gegenreaktionen hervorriefen. Dabei wird die bislang geltende Forschungsmeinung zur Toleranzgeschichte Siebenbürgens in Frage gestellt und völlig neu bewertet
