Change Readiness among Teaching Staff at Anadolu University,Turkey

Turkey’s Anadolu University is one of the world’s largest mega‐universities. It is engaged in strategic planning in response to changes in the expectations of the Turkish Higher Education Council and the community at large. In re‐examining its vision and strategic directions, Anadolu University needs to be informed on the knowledge, skills, and attitudes of its teaching staff, and the systems and support needed to assure their change readiness. This article examines the literature of organizational and educational change and its implications for the university. It reports on a study based on the relevant constructs from the literature and is designed to gauge the extent and nature of teaching staff knowledge, skills, practice, and research in educational and technological change, motivating and de‐motivating factors, change adopter types, and perceptions of the organizational climate for change. It considers the implications of these findings and draws conclusions about what would be needed to improve staff readiness for change.     

Transition from high school to university: a person-centered approach to academic achievement

Although a vast body of studies regarding the variables related to students’ achievement exists, only a handful has investigated how these variables combine and interact together. Such an investigation might make it possible to more accurately illustrate the heterogeneity of students enrolling in university and assess the impact of this diversity on academic achievement. The current study focused on the person-centered approach and investigated the possibility of determining significant subgroups of freshmen in the very first week of the academic year in the Belgian educational context. Using k-mean clustering, 2178 freshmen were classified according to their past performance, socioeconomic status, study choice process, and academic self-efficacy beliefs at the beginning of the first year at university. Analyses of variance were also conducted to analyze the relationship between these student clusters and academic achievement outcomes. Six distinct profiles of students were identified representing different combinations of achievement predictors. Results revealed different odds of success among these profiles. The implications of our approach to the understanding of the heterogeneity of freshmen and the first-year achievement process are discussed.

Private Supplementary Tutoring in the Czech Republic

The study contributes to the literature on private supplementary tutoring by shedding light on this phenomenon in the Czech Republic. The aim of the paper is to identify the reasons for seeking out private supplementary tutoring and to assess the factors underlying its demand. In the representative sample of 1,265 senior upper-secondary school students from two distinct regions of the Czech Republic, 37% acknowledged participation in private tutoring lessons (provided by individuals) and 10% reported enrollment in preparatory courses for university admission (organized by institutions) during their upper-secondary studies. It seems that both enrollment in different educational tracks and specific school subjects are associated with different reasons for taking private tutoring lessons. The results of binary logistic regression suggest that the mother’s educational attainment, family income, students’ academic performance, residence in the capital city, and female gender are significant predictors of students’ enrollment and participation in the explored private tutoring activities. These findings confirm the strong influence of family background on educational attainment identified in previous Czech social-stratification research. In a wider European context, the patterns of private supplementary tutoring resemble those in neighboring countries.     

Microfluidic chip for fast bioassays��evaluation of binding parameters

A seven channel polystyrene (PS) microchip has been constructed using a micromilling machine and a high-temperature assembling. Protein A (PA) has been immobilized by a passive sorption on the microchannel walls. Two bioaffinity assays with human immunoglobulin G (hIgG) as a ligand have been carried out. (i) PA as the receptor and fluorescently labeled hIgG (FITC-hIgG) as the ligand, (ii) PA as the receptor with hIgG as the quantified ligand and fluorescently labeled goat anti-human IgG (FITC-gIgG) as the secondary ligand. One incubation step of the assays took only 5 min instead of hours typical for enzyme-linked immunosorbent assay applications. Calibration curves of the dependence of a fluorescence signal on the hIgG concentration in a sample have been obtained in one step due to a parallel arrangement of microchannels. A mathematical model of the PA-FITC-hIgG complex formation in the chip has been developed. The values of the kinetic constant of the PA-FITC-hIgG binding (k_on=5.5 m³ mol⁻¹ s⁻¹) and the equilibrium dissociation constant of the formed complex (K_d≤3×10⁻⁶ mol m⁻³) have been obtained by fitting to experimental data. The proposed microchip enables fast evaluation of kinetic and equilibrium constants of ligand-receptor bioaffinity pairs and the ligand quantification. As the use of microfluidic chips for immunoassays is often limited by price, we used procedures and chemicals that allow for an inexpensive construction and operation of the microdevice, e.g., temperature assembling as a fabrication technique, detection via an ordinary digital camera, nonspecific polystyrene as a substrate, passive sorption of biomolecules as an immobilization technique, etc.

摄影原稿的艺术加工和制作

一、原稿的含义所谓原稿,是指相对需要复制而言。彩色反转片在未选作制版前,在国外称之为幻灯片,仅作为放映欣赏等用。从印刷制版角度分析,任何事物只要是人的视觉能反映的,均可通过画面重现。
