ABSTRACT This empirical investigation was aimed at conceptualizing, developing and validating a scale for the measurement of the quality of higher degrees by research (HDR-QUAL). For that purpose, this study specifically measured perceptions of higher degrees by research (HDR) students about the constituents of HDR quality in Pakistani tertiary education institutions. Following the 7-step process of scale development, three studies were conducted in order to develop an initial pool of scale items, establishing proposed scale validity and reliability, and assessing nomological behavior of the proposed scale. The principal component analysis with Varimax rotation method resulted in a 3-factor solution, subsequently proposing a 15-item scale. The model fit indices of measurement and the higher-order model indicated a satisfactory fit to data. Finally, the resultant three factors, i.e. financial assistance, supervisory expertise, and infrastructural support, converged into a unidimensional HDR-QUAL scale that was found positively associated with student satisfaction, thus, confirming nomological validity as well. Important policy measures and directions for future research are proposed at the end. 相似文献

The present study carries out an impact analysis of a conditional cash transfer (CCT) program for secondary-school girls in seven districts of Khyber Pakhtunkhwa province in Pakistan, including Battagram, Bonair, Hangu, Kohistan, Shangla, Tank, and Upper Dir. In 2012 we collected household-level primary data and used a probit model for quantitative analysis. Further, we conducted various focus group discussions and key informant interviews in the target areas. Results show that the chances of female schooling decrease with a rise in family size. The chances of female education increase by 1.8 and by 3.3 % if household heads and their spouses have one additional year of schooling, respectively. Better educational services and rises in family income increase the chances of female ecucation by 11 and 0.3 %, respectively. Finally, socioeconomic awareness, improved economic conditions, and CCTs increase the chances of female education by 5.2, 4.7, and 0.03 %, respectively. Overall, the stipend program (CCTs) shows a pareto improvement. Our results indicate that 35 % of girls will drop out in the absence of a stipend program. The present study recommends that to increase program effectiveness, local-level monitoring and program evaluation may be improved, delays in stipend payments to female students should be reduced, a grievance redressal mechanism for parents and guardians should be introduced, and clear synergies should be developed with other transfer programs. 相似文献

Blockchain plays a vital task in cybersecurity. With the exerted efforts for realising large-scale quantum computers, most current cryptographic mechanisms may be hacked. Accordingly, we need a quantum tool utilised for designing blockchain frameworks to have the ability to be executed in the level of digital computers and resist the probable attacks from both digital and quantum computers. Quantum walks may be utilised as a quantum-inspired model for designing new cryptographic algorithms. In this paper, we present a new authentication and encryption protocol based on quantum-inspired quantum walks (QIQW). The proposed protocol is utilized to build a blockchain framework for secure data transmission among IoT devices. Instead of using classical cryptographic hash functions, quantum hash functions based on QIQW are employed for linking blocks of the chain. The main advantages of the presented framework are helping IoT nodes to effectively share their data with other nodes and full control of their records. Security analysis demonstrates that our proposed protocol can defend against message attack and impersonation attacks, thus ensuring secure transmission of data among IoT devices. 相似文献

A multimedia English for Specific Purposes (ESP) programme was developed to train flight attendants. The programme comprised of two units. Unit one is listening comprehension, which provides the flight attendants' with specific information of Airbus A340. Unit two is reading comprehension, which provides the flight attendants with the emergency procedures. The effect of this programme on the flight attendants' safety knowledge and problem solving was measured using an achievement test which comprises two parts; the first part includes 10 multiple‐choice questions based on listening comprehension and measuring safety knowledge; the second part includes 15 multiple‐choice questions based on reading comprehension and measuring problem solving situations. The sample of the study consists of 36 flight attendants divided into two groups. The test was administered as a pretest and a posttest for the equivalence of the groups and their achievement. The results revealed that the computerised ESP programme has a measurable effect on the flight attendants' recall of safety knowledge and problem solving skills. The researchers recommended that similar computerised ESP programmes should be designed in order for the flight attendants to be well equipped with skills and knowledge in dealing with emergency problems that they may occur during flight. 相似文献

Quality assurance of teacher training has become of a great concern nowadays. This paper addresses the quality of BEd programme of the University of Education (UE) Lahore. The main purpose of the study was to evaluate the quality of BEd programme with regard to the internal efficiency of Government Colleges for Elementary Teachers (GCETs), the affiliated institutions of UE. The study was conducted on a random sample of 600 BEd students drawn from 11 GCETs in Punjab province. Data was collected through a questionnaire which was validated through a pilot study in 2006. The reliability of the final questionnaire was established at 0.863 allowing the researcher to launch the study at large scale (Gay, 2000). The findings revealed that BEd programme was effective in terms of updating student teachers' knowledge and skills. Student teachers favoured the quality of BEd curriculum, lesson planning and presentation by themselves and their teacher educators, and had some reservations about the proper use of audio-visual aids for effective classroom teaching learning processes. Female gender showed more satisfaction with the quality of BEd curriculum and teaching than their male counterparts. No significant difference was found in the opinion of the students of GCETs having low, medium, and high enrolment. 相似文献

Rock weathering is defined as the process of rocks alteration as a result of the adjustment of its internal constituents by the action of physical, chemical and biological factors, to the prevailing conditions of the atmosphere and in the environment. In humid polluted areas “red weathering” is one of the major deterioration forms that characterize most granitic rocks. Several intervention steps are required to remove and treat all surfaces affected by this form. It is one of the most aggressive forms of deterioration which are essentially composed of some complex species of clay minerals “Kaolinite, Illite, Montmorillonite and Tosudite”, in addition to some species of salts as “Gypsum” pigmented by “Hematite” as a colorant. After several investigatin techniques, these crusts need several intervention and conservation steps to remove and eliminate the aggressive effects resulted from the red crusts through three essential steps: “cleaning, gap filling and strengthening and stabilizing”. After evaluating all materials and methods that were performed by “DBN, SEM, EDX, and AAS”, the present study suggests that the most suitable cleaning methods are composed of three essential steps “dry and vacuum cleaning (DVC), ultra-sonic cleaning (USC), poultice cleaning (PC)”. Furthermore, the elected gap filling material composed of “Araldite AY-103” mixed with “Granite powder as petro-filler.” Finally, different evaluation methods proved that “Wacker H” is the most suitable strengthening and stabilizing material for consolidation purpose. 相似文献
