This essay reflects upon the themes that emerged from the “Public Relations—An Instrument for the Transformation and Development of Higher Education in Central and Eastern Europe” seminar, for which the articles appearing in this issue of Higher Education in Europe were originally prepared. The transitional public relations approach, which was developed and introduced to the world public relations literature by the author, is used to analyze the impact of this type of public relations on the reform of higher education in the former communist countries of Europe. The main conclusion is that, in view of the common communist heritage of the countries of Central and Eastern Europe, the application of public relations strategies and instruments in higher education accelerates and facilitates reform of this key area of the economy and also causes it to become more effective. The above statement is particularly valid for private universities. 相似文献

Purpose
Metalloproteinases are a key component of the pathogenesis of abdominal hernias. Obesity is considered a risk factor in herniogenesis and hernia recurrence. The aim of this study was to evaluate the serum concentrations of metalloproteinase-2 (MMP-2), MMP-9, MMP-13, and adiponectin in morbidly obese and nonoverweight controls.Materials and methods
The participants were recruited from among patients undergoing bariatric and non-bariatric surgery and divided into two groups: I (body mass index (BMI)≥35 kg/m2, n=40) and II (BMI<25 kg/m2, n=30). Serum concentrations of MMP-2, MMP-9, MMP-13, and adiponectin were measured using enzyme-linked immunosorbent assay (ELISA).Results
A statistically significant difference between groups was observed for MMP-2 concentration. The median MMP-9 concentration was higher in the obese group, but the difference was not statistically significant. Median MMP-13 concentrations did not differ between groups. Serum adiponectin concentration was insignificantly higher in the non-obese group.Conclusions
The elevated serum MMP-2 and MMP-9 concentrations in obese individuals may be related to the higher incidence of incisional hernias in this population.3.

Objective
The aim of this study was to evaluate the concentrations of C-reactive protein (CRP), tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), and the degree of homeostasis model assessment-insulin resistance (HOMA-IR) in patients with morbid obesity exposed to a three-week low-calorie diet and balneotherapy.Methods
The study included 33 patients (25 females and 8 males; mean age 46 years) with body mass index (BMI) values of >40 kg/m2. Evaluations of CRP, IL-6, TNF-α, lipid profile, HOMA-IR, and fasting glucose were carried out before (baseline data) and three weeks after the treatment. The control group consisted of 20 healthy volunteers (15 females and 5 males) with a mean age of 39 years and BMI values of ≤24.9 kg/m2.Results
In the blood of patients with morbid obesity we found significantly elevated levels of CRP, TNF-α, triglycerides, HOMA-IR and fasting glucose, but a decreased level of high density lipoprotein (HDL)-cholesterol, compared with the healthy individuals. The treatment resulted in about a 9.4% reduction in body weight from 122.5 to 111.0 kg and a significant decrease in the concentration of CRP, but no change in TNF-α or IL-6. HOMA-IR was significantly reduced.Conclusion
The decrease in CRP level without changes in TNF-α or IL-6 concentrations after the low-calorie diet and balneological treatment, suggests that an essential amount of adipose tissue must be removed before proper adipocyte function is restored. The decrease in HOMA-IR indicates an improvement in insulin sensitivity, which is beneficial in obese patients.4.

Sliding mode control of manipulators using first-order equations of motion with diagonal mass matrix
Przemys?aw Herman 《Journal of The Franklin Institute》2005,342(4):353-363
This paper presents a proposition of a sliding mode controller for a rigid manipulator expressed in terms of the generalized velocity components (GVC) vector. Introduction of GVC (Trans. ASME J. Appl. Mech. 62 (1995) 216) together with generalized positions leads to two first-order decoupled equations of motion instead of a single second-order equation. It is shown that the new controller, stable in the sense of Lyapunov, has different properties and can, according to Slotine and Li (Int. J. Robotics Res. 6 (1987) 49), give better performance than the classical sliding mode controller. Both control algorithms were tested on a 3 d.o.f., 3-D Yasukawa-like robot. 相似文献

AbstractThe world of radical football fans across Europe is dominated by anti-system groups. While their sympathies in the west of the continent are mostly leftist, the ultras in the east tend to display right-wing attitudes. Poland makes a particularly interesting case in point, as the most intensive and emotional ideological criticism of the processes of ‘transformation’ and ‘modernisation’ is to be observed at the stadiums. As a result of historical developments, opposition against the system in the country can only be expressed using Catholic–patriotic symbolism, which in the case of collective actions of radical football supporters has produced sociocultural and aesthetic effects not to be found anywhere else in Europe. 相似文献

This article provides an ethnographic account of the tensions arising from the different ways of building authority as teachers and the role of higher education in establishing teachers' legitimacy in Russia through the specific example of religious education. After state atheism was abandoned in 1991, an unprecedented demand for religious knowledge appeared in Russia, in particular in relation to Russian Orthodoxy. Since the Russian context of Orthodox education lacks shared standards, there is considerable latitude in the criteria determining norms and rules. Seeking to increase its influence, the Russian Orthodox Church aspires to have Orthodox catechism taught in a systematic way both in parishes and in secular schools. In practice, the Church is encouraging professional pedagogues to submit their curriculum proposals that would be suffused with Orthodoxy and at the same time be eligible for adoption in all settings and institutions. Thus, in order to educate teachers of religion, the Church has made available multiple, diverse sources of religious knowledge (self-learning, various courses offered by the eparchies, Spiritual Academies, and other institutions of higher education). But the legitimacy of these sources is often questioned, for instance by asking whether the institution that delivers diplomas of religious higher education has been granted formal state recognition. The teachers' quest for being acknowledged as competent technicians of religious education leads to competing claims for the authenticity of the sources of their training. 相似文献
