Existing research indicates that emotions are integral components of teachers’ jobs and lives, but knowledge regarding functional relations between teachers’ emotions, their antecedents and their effects on teachers, teaching and students is still quite scarce. One possible reason for this knowledge gap is the lack of adequate operationalisation of the teacher-emotion construct. Thus, the aim of this research was to develop a psychometrically grounded and contextually specific multidimensional self-report instrument aimed at assessing the specific emotions teachers experience in relation to their work and profession. Based on the contemporary component definition of emotion, and using a mixed-method approach (qualitative and quantitative), through a series of five empirical studies (N1 = 25, N2 = 300, N3 = 315, N4 = 391 and N5 = 1314), the Teacher Emotion Questionnaire (TEQ) has been developed. The instrument contains scales assessing emotions of joy, pride, love, fatigue, anger and hopelessness. All scales have adequate psychometric characteristics and are theoretically meaningfully related to the criterion variables examined. Added value of the TEQ scales over the more general measures of affect is also demonstrated. 相似文献

Virtual chat services represent an exciting way to provide patrons of medical libraries with instant reference help in an academic environment. The purpose of this article is to examine the implementation, marketing process, use, and development of a virtual reference service initiated at the Massachusetts College of Pharmacy and Health Sciences and its three-campus libraries. In addition, this paper will discuss practical recommendations for the future improvement of the service. 相似文献

We present a low cost microfluidic chip integrating 3D micro-chambers for the capture and the
analysis of cells. This device has a simple design and a small footprint. It allows the
implementation of standard biological protocols in a chip format with low volume consumption. The
manufacturing process relies on hot-embossing of cyclo olefin copolymer, allowing the development of
a low cost and robust device. A 3D design of microchannels was used to induce high flow velocity
contrasts in the device and provide a selective immobilization. In narrow distribution channels, the
liquid velocity induces a shear stress that overcomes adhesion forces and prevents cell
immobilization or clogging. In large 3D chambers, the liquid velocity drops down below the threshold
for cell attachment. The devices can be operated in a large range of input pressures and can even be
handled manually using simple syringe or micropipette. Even at high flow injection rates, the 3D
structures protect the captured cell from shear stress. To validate the performances of our device,
we implemented immuno-fluorescence labeling and Fluorescence in Situ Hybridization
(FISH) analysis on cancer cell lines and on a patient pleural effusion sample. FISH is a Food and
Drug Administration approved cancer diagnostic technique that provides quantitative information
about gene and chromosome aberration at the single cell level. It is usually considered as a long
and fastidious test in medical diagnosis. This process can be easily implanted in our platform, and
high resolution fluorescence imaging can be performed with reduced time and computer intensiveness.
These results demonstrate the potential of this chip as a low cost, robust, and versatile tool
adapted to complex and demanding protocols for medical diagnosis. 相似文献

Research Findings: This paper reports on children's use of science materials in preschool classrooms during their free choice time. Baseline observations showed that children and teachers rarely spend time in the designated science area. An intervention was designed to “market” the science center by introducing children to 1 science tool, the balance scale. Baseline measures showed that children did not know the scale's name or function. The intervention was expected to increase children's use of the science area and their knowledge about the scale. Children's voluntary presence and exploration in the science area increased after the balance scale intervention compared to in comparison classrooms. Furthermore, children who participated in this intervention demonstrated improved knowledge about the scale's function, whereas students in the comparison group did not. Practice or Policy: Adults can increase children's autonomous exploration of science tools and materials, and their knowledge about them, by offering particular kinds of large-group learning experiences. 相似文献

When looking for answers to the question of academic (non)achievement of regular pupils and pupils with special needs, it is necessary to take into account the extraordinary complexity of factors, ranging from psychological across instructional to home environment variables. The academic achievement is not only a reflection of the pupil’s knowledge, but is also influenced by the pupil’s behaviour, the teacher’s expectations and finally the relationship established between the teacher and the pupil. This paper contributes answers to the question which of the traits, perceived by teachers, explain the academic achievements of regular pupils and pupils with special needs. Our analysis shows that perceived traits that explain the academic achievement of regular pupils refer to academic as well as social behaviour, disruptive behaviour and self-regulatory behaviour; therefore, they cover all areas of perceived traits we studied. In pupils with special needs as a whole and in particular groups of pupils with special needs, the factor which presents disruptive social behaviour proved as insignificant, which consequently means that the academic achievement of pupils with special needs depends more on academic and self-regulatory behaviour, task activity and social inclusion. 相似文献

Thirteen samples of an efflorescence collected from the surface of beeswax seals or from beeswax used for their restoration were analysed in detail. The samples were of different origin, age and storage history. The composition and the incidence of the efflorescence was correlated with a chemical composition of historical and recent beeswax samples. The composition of the crystalline layer was found to be very similar in all the samples. Linear monounsaturated alkenes containing 31 and 33 carbon atoms, more precisely (Z)-hentriacont-10-ene and (Z)-tritriacont-10-ene, were identified as main components. The analyses of beeswax have revealed that all compounds identified in “wax bloom” naturally occur in recent beeswax. However, the historical beeswaxes contained only traces of unsaturated hydrocarbons, if anything. The efflorescence was observed primarily on the surfaces of those samples which contained larger proportion of alkenes. The presented results could be of particular importance not only for better understanding of the described phenomenon, but also for the development of new beeswax-based materials, which would be “bloom resistant” and useful for conservation purposes. 相似文献

In the research in the field of inclusiveness it is often neglected how inclusiveness is constructed differently within the so-called Anglo-American and continental educational contexts. In Slovenia, the field of educational studies has historically developed within the continental, particularly German tradition, as a discipline called Pedagogy at the Faculty of Arts. Since Pedagogy is fundamentally theorising the processes of becoming a free human being and does not take a particular interest in the issues of vulnerable social groups, a complementary area of tertiary study emerged in today's Faculty of Education (e.g. Special needs Pedagogy). However, recently we can identify a trend of emerging new study programmes, the so-called inclusive education. Because of this separation between scientific fields, this paper is dealing with a question of which of the disciplines is offering a more convincing answers to the question of how to conceptualise and implement the inclusiveness. Using qualitative analyses of the concept of inclusiveness and content analyses of Slovenian study programmes and courses related to inclusive education, we attempt to show that discipline of Pedagogy provides a conceptualising of inclusiveness that is more complex through successfully interweaving the humanistic and social paradigm. 相似文献
