Active crystal facets can generate special properties for various applications. Herein, we report a (001) faceted nanosheet-constructed hierarchically porous TiO₂/rGO hybrid architecture with unprecedented and highly stable lithium storage performance. Density functional theory calculations show that the (001) faceted TiO₂ nanosheets enable enhanced reaction kinetics by reinforcing their contact with the electrolyte and shortening the path length of Li⁺ diffusion and insertion-extraction. The reduced graphene oxide (rGO) nanosheets in this TiO₂/rGO hybrid largely improve charge transport, while the porous hierarchy at different length scales favors continuous electrolyte permeation and accommodates volume change. This hierarchically porous TiO₂/rGO hybrid anode material demonstrates an excellent reversible capacity of 250 mAh g^–1 at 1 C (1 C = 335 mA g^–1) at a voltage window of 1.0–3.0 V. Even after 1000 cycles at 5 C and 500 cycles at 10 C, the anode retains exceptional and stable capacities of 176 and 160 mAh g^–1, respectively. Moreover, the formed Li₂Ti₂O₄ nanodots facilitate reversed Li⁺ insertion-extraction during the cycling process. The above results indicate the best performance of TiO₂-based materials as anodes for lithium-ion batteries reported in the literature.  相似文献   

Metaphorical images of an organization: the power of symbolic constructs in reading change in higher education organizations     

Hasan Simsek 《Higher Education》1997,33(3):283-307

Based on interviews with 24 faculty members at a large, public university, this article reports the use of metaphors as a new conceptual strategy to analyze change in higher education organizations. Results of the study indicate that strategic choices guiding the behavior of the organization under study and the metaphorical images held by the faculty members about their organization show a high degree of congruence. Implications for change and maintenance of enacted realities in higher education organizations are discussed.  相似文献   

A Palestinian prominent educator’s predicament: Khalil Sakakini’s ambivalence and inner contradictions towards Jews and Zionists during the British Mandate 1920–1948     

Kamal Hasan Moed 《History of education》2013,42(6):769-783

British rule over Palestine between 1920 and 1948 was a vibrant and fateful period in the modern history of the country in all arenas (political, economic, societal, demographic and cultural), one of the most active of which in Palestinian society at the time was education. Many Palestinian educators assumed their role as freedom fighters, agents of Arab nationalism and defenders of the homeland. These educators saw the British and the Zionists as bitter enemies to be resisted and expelled, though some had a distinctly progressive humanistic vision that allowed them to view the collective enemy as worthy human beings. This complex reality created many internal contradictions and difficulties among these humanistic educators, led by prominent Palestinian educator Khalil al-Sakakini (1878–1953). This article attempts to describe and understand Sakakini’s contradictions and internal conflicts and how he dealt with these internal contradictions and distinguished between Jews and Zionists.  相似文献   

Enhancing the wellbeing of the elderly: Social use of digital technologies in aged care     

Helen Hasan  Henry Linger 《Educational gerontology》2013,39(11):749-757

ABSTRACT

As developed countries struggle to find suitable living arrangements for their ageing populations, many elderly citizens are becoming increasingly marginalized and isolated. In similar circumstances, younger people would use digital technologies to stay occupied and connected, but few elderly citizens have this capability. Our research investigates the ways that the social wellbeing of elderly citizens, wherever they reside, can be enhanced by their use of information and communications technologies (ICT), particularly digital technologies. A 2-year action research study of the social use of ICT by residents in aged-care facilities was conducted in order to determine how developing digital capabilities could enhance their wellbeing. Research interventions included the establishment of computer kiosks in aged-care facilities and weekly classes for developing ICT skills. As their digital capability improved, many of the elderly residents were observed to engage in meaningful computer-based activities of their own choosing. A set of themes among these activities was identified: connection, self-worth/esteem and personal development, productivity, occupation, self-sufficiency, being in control, and enjoyment. Our results are consistent with recently reported domains of social wellbeing among recipients of community-based aged-care services: (a) social participation and involvement, (b) occupation, (c) control over daily life and (d) dignity.  相似文献   

Examining the implementation of two co‐teaching models: team teaching and station teaching     

Hasan Gurgur  Yildiz Uzuner 《International Journal of Inclusive Education》2013,17(6):589-610

In Turkey, the number of students in mainstream education is increasing, and a support service does not exist even though mainstreaming has been implemented for many years. Therefore, within this system, many students with special needs are failing. Thus, there is a need for evidence‐based research projects concerning the ways of supporting these students such as the co‐teaching approach. In the research detailed in this article, the participants were one regular education teacher and the researcher as special education teacher. The design of the study was action research. Data collection techniques were a checklist, documents (lesson plans, students’ products), researcher journal, actual recordings of co‐planning and reflection meetings and instructions. The findings were demonstrated based on the co‐planning meetings, teaching practices and reflection meetings. Concerning the challenging issues of implementation, support services should certainly be provided in the mainstream classes, and additional research is needed to systematically examine the impacts of teachers taking time to undertake common planning and/or discussing student performance.  相似文献   

Academic and Non-Academic Staff's Psychological Contract in Turkey     

&#;nayet Aydin  Kür&#;ad Yilmaz  Hasan Basri Memduho&#;lu  Ebru O&#;uz  Sabri Güngör 《Higher Education Quarterly》2008,62(3):252-272

Studies of psychological contract as part of organisation-individual agreements have become important in recent years. This study determines views, about the psychological contract, of academic and non-academic staff and managers in faculties of education in Turkey. A total of 442 employees at 11 state universities in Turkey were included in the research. 'Psychological Contract Inventory' and 'Psychological Contract Measures', designed by Rousseau were utilised during the development process of the data-gathering tool. After the adaptation work, the scale consisted of 68 items under three sections and seven subscales. The results showed that academic staff and executives considered that their university carried out its obligations towards the staff at a 'moderate' level, whereas the non-academic staff considered it 'insufficient'. The academic and the non-academic staff considered that the employees carried out their tasks at a 'maximum' level, whereas the executives considered it 'moderate'.  相似文献   

Ways of Meaning,Ways of Learning: Code as an explanatory concept     

Ruqaiya Hasan 《British Journal of Sociology of Education》2002,23(4):537-548

The aim of this paper is to offer further empirical evidence in support of Bernstein's concept of code from the social semiotic perspective of systemic functional linguistics. When the concept of code was first introduced in the 1960s, it was severely criticised by many famous socio-linguists. It will be argued that these socio-linguists failed to understand the significance of language as a meaning potential, and so they also failed to appreciate the inherent relation between meaning and mental development (Halliday, 1975; Vygotsky, 1978). The concept of code is important in any viable theory of mental development which does not hide behind a mythical homogeneity. Human beings develop different forms of consciousness, and code theory offers a detailed and coherent account of both the social origin and the nature of this variation. In fact, the panoramic scope of Bernstein's sociological theory clarifies the relations of social positioning, coding orientation, communication, and consciousness to learning in official pedagogic sites. In presenting some of the results of my investigation in variant forms of communication between mothers and their young children, I will show that: (a) the variation is systematic, (b) the nature of the variation needs Bernstein's code theory for its interpretation, and (c) the fact of variation can only be accounted for by its relation to social positioning.  相似文献

Communication in an academic context   总被引：2，自引：0，他引：2  

Sidika?GizirEmail author  Hasan?Simsek 《Higher Education》2005,50(2):197-221

The purpose of this qualitative case study is to investigate the most common communication problems from the views of faculty members at the Middle East Technical University in Ankara, Turkey. The sample of this study consists of 50 faculty members including professors, associate professors, assistant professors, and instructors from five largest departments representing five colleges at the Middle East Technical University. The data were gathered by utilizing interview method, including 19 interview questions which were developed by the researchers. The data collected through interviews were content-analyzed including the process of identifying, coding, and categorizing the primary patterns of data. The results of this study provide evidence that faculty members perceive a number of significant communication problem areas regarding work-related communication and overall departmental communication. Furthermore, although there are some similarities among the faculty members in identifying communication problems as well as the ways of solving these communication problems, some significant differences are also observed among the departments. In addition, analysis of the data revealed that there are some similarities and differences between hard science and soft science departments in defining communication problems and possible ways of solving these communication-related problems.  相似文献
