On the Reconstruction of Teachers’Role of Business English Reading Classroom Teaching Based on Literature Circle

Business English reading teaching under the mode of“literature circles”focuses on cultivating students’autonomy in reading,group cooperation,and the exchange of ideas among group members.In this teaching mode,teachers are no longer the masters of the reading classroom,but the helpers,participants,and researchers in the process of students’reading.The reconstruction of teachers’role can promote the benign development of relationship not only between teachers and students,but also between students and students,inject new impetus and vitality into the classroom,and improve students’reading literacy.

Teacher's Role in the Oral English Class

English speaking has been paid more attention today, especially in the age of globalization. Teachers are attempting to find out more effective methods to enhance the teaching results of English speaking. Facing the great demands and present difficulties of oral English classes, teachers have to conduct more study and practice to find out what roles that an oral English teacher has to take in the oral English classroom. Compared with the traditional teaching role in the English classroom, an oral English teacher has to fulfill more than one role in the classroom teaching so as to provide better learning conditions for students. Lacking more exposure to the real interaction with native speakers, students expect the oral English teacher to be a creator of the language environment. With various teaching and learning activities in the oral English classroom, the teacher has to be a good organizer to ensure every student to achieve improvement. An oral English teacher also has to correct students'language errors while ensuring the smooth progress of the classroom teaching. Only when an oral English teacher make clear what roles he or she has to take in the classroom can he or she achieve effective teaching.

Least Privileges and Role’s Inheritance of RBAC

The main advantages of role-based access control （RBAC） are able to support the well-known security principles and roles＇inheritance. But for there remains a lack of specific definition and the necessary formalization for RBAC, it is hard to realize RBAC in practical work. Our contribution here is to formalize the main relations of RBAC and take first step to propose concepts of action closure and deta closure of a role, based on which we got the specification and algorithm for the least privileges of a role. We propose that roles＇ inheritance should consist of inheritance of actions and inheritance of data, and then we got the inheritance of privileges among roles, which can also be supported by existing exploit tools.

Role of P,S and B on Creep Behavior of Alloy 718

The doping of phosphorus, sulfur and boron in IN718 superalloy can remarkably influence the creep behavior. The modifications of the minor elements seem not to vary the stress exponent and the influences primarily concentrate on the effective diffusion coefficient. A pronounced beneficial interaction between P and B and a weaker detrimental interaction between P and S have been obtained. The preexponential frequency constant is proved to be strongly related with the creep activation energy because of the so-called compensation effect. The compensation temperature has been determined to be about 1080 K, which corresponds to the transformation temperature from rapidly coarsened γ'' phase to δ phase. It has been proposed that trace elements can influence the effective diffusion coefficient individually or cooperatively, which in turn either retard or speed the creep process.

Putative roles of cathepsin B in Alzheimer's disease pathology: the good, the bad, and the ugly in one?

Alzheimer＇s disease（AD）is a fatal progressive neurodegenerative disorder characterized by loss in memory,cognition,and executive function and activities of daily living.AD pathogenesis has been shown to involve loss of neurons and synapses,cholinergic deficits,amyloid-beta protein（Aβ）deposition,tau protein hyperphosphorylation, and neuroinflammation.

The role of DJ-1 complexes and catecholamine metabolism： relevance for familial and idiopathic Parkinson＇s disease

Autosomal recessive mutations in the PARK7 gene,which encodes for the protein DJ-1,result in a loss of function and are a cause of familial Parkinson’s disease（PD）,while increased wild-type DJ-1protein levels are associated with some forms of cancer.Several functions of DJ-1 have been described,with the greatest evidence indicating that DJ-1 is a redox-sensitive protein involved in the regulation of oxidative stress and cell survival.

Teachers＇ role in vocabulary teaching： Strategies for vocabulary teaching

Much research has been done on how to help students to improve their language skills of listening, speaking, reading, and writing, but how to help students with the acquisition of vocabulary which is essential to the development of language skills has been neglected. This paper is an attempt to explore the teacher＇s role in helping students with vocabulary acquisition. Word knowledge is discussed, selection of words to be taught, techniques for presentation and strategies for self-learning.

The Changing Role of Chinese Women in History--From the Dream of Red Mansions to the Moment in Peking

In the history of feudal society,women were suffering from the oppression and inequality in their family and status,and also strict restriction from the society.Their freedom was limited and they could not make full use of their wisdom,and abili ty.But the role of women did not stay the same during the feudal society.It had changed though the fundamental role remained the same.Here in this essay,it mainly talked about the changing role of Chinese in history,from the beginning of the Qing Dy nasty to the end of the Qing Dynasty.It collected information,and evidences from two books which were of great value to inves tigate women's role.They were Cao Xueqin's the Dream of Red Mansions and Lin Yutang's Moment in Peking.A great por tion of these two book's main characters were women,no matter what their social statuses were,no matter what roles they were playing in the big feudal family.Based on the result of analysis,the study suggests that women have been making progress all the time in changing their situation.And the development of economy has given women immense chances to achieve their self-actu alization.

Discussion on Teacher's Role under Life Threatening Circumstances

This paper first reviewed a controversial case in which a teacher ran away from his students in a earthquake. Several educational ethnic questions were aroused from the case: Is protecting students part of teacher's job? To what extent should it be applied? etc. Then the author aims to answer these questions based on a real case study from philosophical perspective, that is, analyzing teacher's role(i) as a human being;(ii) as a educator;(iii) as a educatee. Finally the paper concludes that teachers should protect their students even under life threatening circumstances.

An Analysis of the Readers' Roles in the Construction of Meaning in John Donne's The Flea under Reader-Oriented Theory

Among the sundry studies in China on John Donne's The Flea,there has been none done from the perspective of Reader-Oriented Theory to probe into the readers' roles in the construction of meaning.The present article under Wolfgang Iser's theories,in a further pursuit of the expansion of the gestalt of such studies on the poem,aims at exploring the readers' active roles in complementing,completing and recreating the textual meaning,and differentiating the implied reader and the actual reader through the poem as well as attempting to fulfill the construction of the reading cognitive model through the interpretation of the conceit the flea.

Disaster and Nurse’s Role

India is vulnerable to a large number of disasters.More than 58.6%of the landmass is prone to earthquakes of moderate to high intensity;over 40 million hectares(12%)of its land is prone to floods and river erosion;close to 5.700 km,out of the 7.516 km long coastline is prone to cyclones and tsunamis;68%of its cultivable area is vulnerable to droughts;and,its hilly areas are at risk from landslides and avalanches.The WHO defines disaster as any occurrence that causes damage,ecological disruption,loss of human life,deterioration of health,and health services,on a scale sufficient to warrant an extraordinary response from outside the affected community or area.Roles of nurse during disaster management include to determine the magnitude of the event,define and understand the health needs of the affected groups,prepare the priorities and objectives,identify actual and potential public health problems at the earliest,and estimate resources needed to respond to the needs identified.

Reconciliation of Theoretical Lifetimes of the 5s5p^(3)P_(2)^(o) Metastable State for ^(88)Sr with Measurement: The Role of the Blackbody-Radiation-Induced Decay

We conducted measurement and calculation to resolve the long-standing large discrepancy in the metastable state lifetime for the ^(88)Sr atom between theoretical and experimental results. The present lifetime τ = 830_(-240)^(+600)s,measured using the magneto-optical trap as a photon amplifier to detect the weak decay events, is approximately60% larger than the previous experimental value τ = 520_(-140)^(+310)s. By considering the electron correlation effects in the framework of the multiconfiguration Dirac–Hartree–Fock theory, we obtained a theoretical lifetime of 1079(54) s, which lies in the range of measurements with error bars. Furthermore, we considered the higher-order electron correlation and Breit interaction to control the uncertainty of the theoretical calculation. The significant improvement in the agreement between calculations and measurements is attributed to the updated blackbody radiation-induced decay rate.
