时间的生长与静止

生于巴西的Mona Kuhn 2009年重返故地拍摄Native系列,是一场将人体与风景连为一体,通向一场内在的尤利西斯之旅。此后Kuhn拍摄了新系列Bordeaux,同样将人体与自然风景分离并融合,所有的风景照片则均以黑白呈现,时间在恬静又略带神秘气息的庄园与树林中停滞,成了关于永恒的暗示。时间或许是这一系列的关键,具象的和抽象的,流动的和静止的。     

Use of digital game based learning and gamification in secondary school science: The effect on student engagement,learning and gender difference

This study aimed to identify the impact of a game based learning (GBL) application using computer technologies on student engagement in secondary school science classrooms. The literature reveals that conventional Science teaching techniques (teacher-centered lecture and teaching), which foster rote learning among students, are one of the major concerns in Pakistan Education system. This leads to student disengagement in science lessons eventually resulting in student absenteeism and dropouts from the schools. This study consisted of five stages: (1) examining the impact of Digital Game-Based Learning (DGBL) and gamification on engagement, learning and gender difference, and literature related to using DGBL models for instructional design; (2) planning learning activities and developing a GBL application based on a specific content in Science; (3) conducting an intervention with a sample of 72 participants of 8th grade (aged 12–15) in a low cost private school of Pakistan following quasi-experimental research framework; (4) observing behaviour and emotions of the participants during science lessons; (5) conducting pre and post tests to assess the learning outcomes of participants followed by focus groups discussion. Analysis from Friedman test, Mann-Whitney U test, and Wilcoxon Signed Rank test show that the GBL application has a positive influence on student engagement. However, GBL application was not equally effective for all students since girls outperformed boys in terms of engagement and learning outcomes. This study gives insights into the development of better educational games to promote student learning.     

Synthesis of singly-terminated ladder networks by multivariable array using homogeneous polynomials

This paper discusses a multivariable array whose elements are multivariable homogeneous polynomials which may have missing terms in any of the variables. This array permits one to obtain conditions for the realizability of a driving-point function or a transfer function as a resistively terminated low-pass ladder network. By reac- tance transformations, other forms of ladder structures can be obtained. The case of cascade-separable ladder networks is discussed in detail.

Soziale Ungleichheit beim Zugang in eine Berufsausbildung: Welche Bedeutung haben die Institutionen?

The corporatistic governance model of nonacademic vocational training, which is predominant in Germany, has produced heterogeneous and complex conditions for the access to vocational training. Which training programs are offered and the selection of applicants is largely determined by the training companies themselves. Adolescents interested in vocational training are thus confronted with diverse admission requirements. Which resources they can and have to use in order to receive a training position is significantly determined by the respective admission requirements. The present paper elucidates key institutional conditions of the access to vocational training which can serve as explanations for the (re-)production of social inequalities in the transition process from school to vocational training. In particular, the inequalities with respect the admission to vocation training along the lines of educational degrees, gender, as well as regional, social, and ethnic backgrounds are investigated.     

Examining the antecedents of e-loyalty intention in an online reservation environment

Online reservation has increased significantly in recent years. Understanding how customers behave towards this technology is considered to be important to interested parties, such as travel agencies and tourism marketing managers, in order to enable them to improve their marketing strategies, which would, in turn, allow them to retain their customers. This paper presents findings about the antecedents of e-loyalty intention towards online reservation among 288 respondents in the United Arab Emirates. The research examines the role of e-service quality, hedonic and utilitarian values, satisfaction, and subjective norms in motivating loyalty intention towards online reservation. The results show that e-service quality has a significant influence on hedonic and utilitarian values, which, in turn, affect customer satisfaction. Moreover, satisfaction and subjective norms positively affect e-loyalty intention towards online reservation.     

Tide–surge interaction model including air bubble effects for the coast of Bangladesh

An estimate of water levels due to the interaction of tide and surge associated with a storm including air bubble effects is made along the coastal region of Bangladesh. For this purpose, a vertically integrated shallow water model in Cartesian coordinate system is developed introducing air bubbles and is solved using nested finite difference schemes. A fine grid model covering the region between 21°15′N to 23°N and 89°E to 92° E has been nested into a coarse grid model covering the region between 15°N to 23°N and 85°E to 95°E in the Bay of Bengal to incorporate all the major islands and coastal bending accurately. By applying tidal forcing through the southern open boundary of the coarse grid model appropriate tidal conditions are generated in the problem domain. Numerical experiments are performed with the help of the model to simulate water levels due to tide and surge interaction including air bubble effects associated with the tropical storm of April 1991. The model results are found to be reasonable and the model can be found to simulate higher water levels in the presence of air bubbles.     

Effectiveness of public and private sector agricultural extension: Implications for privatisation in Pakistan

Worldwide serious reservations are being expressed about the ability and competency of the public sector to deliver agricultural extension services, especially in developing countries such as Pakistan which is faced with serious financial difficulties. Consequently, the government is looking for alternative extension paradigms that are cost-effective and client-oriented. To this end the government of Pakistan is inclined towards privatizing the provision of agricultural extension services as a means to promote a second ‘Green Revolution’. This study was conducted among cotton farmers in the Punjab Province to examine the comparative effectiveness of public and private sector extension as perceived from the stakeholders. Data were collected from 52 contact farmers of both extension systems. A number of biases were identified in both systems; namely, a preference for farmers with better education and larger landholdings than their noncontact farmer counterparts. Overall, neither system appears to be working for the benefit of the wider farming community.     

Physical and psychosocial aspects of the learning environment in the science laboratory and their relationship to teacher satisfaction

This paper is a report of a survey conducted to determine teachers’ perception of the science laboratory learning environment and the relationship between different aspects of this environment and satisfaction from teaching and learning. Teachers’ perceptions of psychosocial aspects were measured by use of the Science Laboratory Environment Inventory (SLEI), whereas perceptions of physical aspects were measured by use of the Physical Science Laboratory Environment Inventory. The level of satisfaction was measured by use of a satisfaction scale (SC). Data were collected from 800 science teachers in secondary schools in Malaysia. Analysis of findings revealed that teachers have positive attitudes on all SLEI scales, with the exception of the open-ended scale. In terms of physical aspects, teachers regard lighting and technology as highly important but furniture and equipment, space, air quality and safety as of moderate importance only. Results also showed that teachers’ satisfaction from teaching in the laboratory was positive. Subsequent analysis revealed a significant predictive relationship between teachers’ perception of science laboratory learning environments and their teaching and learning satisfaction.     

School‐to‐work transition services for students with disabilities in Malaysia: organisations' views on policy and practices

Transition services are required by law for students with disabilities in many developed countries. In Malaysia, however, there is still no specific legislation mandating that school‐to‐work transition planning and services be provided to students with disabilities. This study investigated the state of the transition services provided by educational organisations to students with disabilities in Malaysia. A mixed method research design, which utilises both quantitative and qualitative research techniques, was employed to obtain information from 23 government organisations and NGOs involved in the education and training of students with disabilities. This study found that the organisations surveyed were aware of the lack of transition support and call attention to the importance of instituting a national policy on school‐to‐work transition services and supported employment systems for students with disabilities. The legislative and educational implications for Malaysia are discussed.
