¡§Team¡¨ has been the essential working unit for companies nowadays. Researchers do not regard it as an important issue of telling ¡§groups¡¨ from ¡§teams¡¨ for team research, because they are all for being interdependent and being responsibility-apportioned working units, and the former is the major characteristic of being a team. The writer aims at mission-interdependent and affiliation-interdependent working departments, which being referred to the past research, meanwhile taking team personality and transformational leadership as independent variables, team efficacy as dependent variable, and coherence as the major medium. The writer released 795 questionnaires to the working units in hospitality and tourism industry, including 103 questionnaires to management level, 692 to subordinates level, totally 103 work units, eventually ended up effective 418 questionnaires in 66 units with 64.08% return rate for work units and 52.58% return rate for individuals. The findings are as follows. 1.The agreeableness of team personality, and the ideal influence, spiritual encouragement and talent development of transformational leadership have positive influence on team cohesion. 2.Team cohesion is indeed helpful to team efficacy enhancement. 3.Team cohesion merely has partial medium to team personality, transformational leadership and team efficacy.

Based on a proposed input-process-output model of team goal, leader goal orientation, team cohesion, and team effectiveness, this study examined the influences of the leader trait goal orientation on the relationships between team goals and team cohesion. Results from 73 five-person teams working on an interdependent command and control simulation game indicated that team learning goal positively relates to team viability. Social cohesion mediates the effects of a team learning goal on team viability. In addition, the leader’s learning orientation moderates the effect of a team learning goal on team task cohesion. Results of supplementary analyses are also presented. Theoretical and practical implications are discussed, as well as possible limitations and directions for future research.

It is widely acknowledged that political activities can not exist without language. Both politics and language are interrelated concepts. The relation between politics and language are widely investigated in terms of textual analysis based on language of politics. As Paul Anthony Chilton and Christina Schäffner state in the book Politics as text and talk: analytic approaches to political discourse: “<…> Aristotelian view <…> for language would have evolved to perform social functions – social functions that would in fact correspond to what we understand as ‘political’.”(Chilton and Schäffner 2002:2) Furthermore, Adrian Beard wrote how both language and politics are interrelated in his book The Language of Politics (2000:18). The author provided textual analysis of language in political discourse. The bachelor thesis explores how cohesion is used in political discourse. In this Research, Hansard, official reports of British Parliamentary debates, have been used to investigate the phenomenon of cohesion. In this paper the term “Hansard” is applied to refer to an official report of British Parliamentary debates. To be precise, two dictionaries have been chosen to define the term “Hansard”. Oxford Guide to British and American Culture for Learners of English provides the following definition of the concept “Hansard”: “the informal name for the Official Report of everything that is said in the British parliament, and in its committees.” (Oxford Guide to British and American...

Main feature of the cohesion is connection between sentences in the text. It describes the ways in which components of sentences of a text are mutually connected (grammatically and lexically). Cohesion is non-structural text forming relations because cohesion depends not on structure but on semantic relations and it makes the text a semantic unit. / Pagrindinis kohenzijos tikslas yra ryšys tarp sakinių tekste. Ji apibūdina abipusį ryšį kuris jungia sakinius(gramatinį ir leksinį). Kohenzija yra nestruktūrinis teksto formavimo ryšys, ji nepriklauso nuo struktūros, tai semantinis ryšys ir tuo pačiu jis nurodo, kad tekstas yra semantinė dalis.

When solid particles of different types are mixed together, a random distribution of the components is rarely produced and deterioration of the mixture can occur on subsequent handling. Among the microscopic processes responsible, one important mechanism for free-flowing materials is thought to be interparticle percolation, the drainage of particles through the interstices between larger ones. If the larger particles are stationary this is called spontaneous percolation, whereas if it is produced by shear strain the term strain-induced percolation is used. Here a quantitative evaluation of both and some consequences are described. A practical application of spontaneous percolation has been the design and construction of a new static mixer or distributor, consisting of rows of angle bars mounted horizontally in a vertical channel. Material fed to the top of a unit bounces off the bars and is distributed across the channel. Two mixers were built; one dispersed material in one lateral direction only and could be used for feeding material onto a belt or distributing seed from a moving vehicle. The other produced a two-dimensional dispersion and would be useful in distributing material flowing into hoppers or whenever a good mixture were required. Optimisation of the design was investigated using a computer program which simulated the motion of a spherical particle as it fell through such a mixer. Design data was deduced from the record of the position of the particle. The mixers were not suitable for use with fine materials. Interpretation of experimental results from this equipment requires suitable statistical indices and two were developed here. One related the variance of sample compositions to the number of particles fed to the mixer by assuming that the distributions of material were ordered. The second, using the correlation coefficient between samples, related the variance to the sample size in those situations where two orthogonal processes are in operation. Both techniques are generally applicable to fields other than that of powder mixing. On the theoretical side, an existing model of spontaneous percolation for inelastic materials has been extended and improved. The original form did not account for the motion of a particle between collisions with bulk particles but this has now been included. An entirely new semi-empirical model for partly elastic materials has also been proposed. Both predict percolation velocities which agree with experimental data. In order to extend earlier experimental studies on strain-induced percolation, a simple shear cell was modified by installing a hydraulic drive which enabled the cell to be driven at a constant speed. Advantages of the use of such a cell include the possibility of detecting a percolating particle on entry to and exit from the bed and the constant strain throughout the material. Reliable and accurate readings of residence times of percolating particles were recorded and percolation velocities and both lateral and axial diffusion coefficients were calculated. These were functions of the relative particle size and density, the material properties of the percolating particle and bed conditions such as strain rate and normal stress Denser and softer particles percolated faster. Decreasing the diameter ratio between percolating and bulk particles from 0.67 to 0.27 caused a twenty-five fold increase in the percolation rate. The dependence of this rate on particle diameter was interpreted using statistical mechanics. The percolation rate has been shown to reach a constant value as the strain rate increases, in contrast to the deductions drawn in earlier work by Scott, whose procedure has been proved to be unsound.
