    Subjective outcome evaluation findings based on the perspective of the participants of the Project P.A.T.H.S. (Positive Adolescent Training through Holistic Social Programmes) in nine datasets collected from 2005 to 2009 (n = 206, 313 program participants) were examined in this paper. Based on the consolidated data with schools as units, results showed that the participants generally had positive perceptions of the program, implementers, and benefits of the program. More than four-fifths of the participants regarded the program as beneficial to their holistic development. Multiple regression analysis revealed that the perceived qualities of the program and the program implementers predicted perceived effectiveness of the program. Based on the subjective outcome evaluation findings, the present study provides support for the effectiveness of the Tier 1 Program of the Project P.A.T.H.S. in Hong Kong

    A Physics-based prognostics approach for Tidal Turbines

    This is the author accepted manuscript. The final version is available from IEEE via the DOI in this recordTidal Stream Turbines (TST) have the potential to become an important part of the sustainable energy mix. One of the main hurdles to commercialization is the reliability of the turbine components. Literature from the Offshore Wind sector has shown that the drive train and particularly the Pitch System (PS) are areas of frequent failures and downtime. The Tidal energy sector has much higher device reliability requirements than the wind industry because of the inaccessibility of the turbines. For Tidal energy to become commercially viable it is therefore crucial to make accurate reliability assessments to assist component design choices and to inform maintenance strategy. This paper presents a physics-based prognostics approach for the reliability assessment of Tidal Stream Turbines (TST) during operation. Measured tidal flow data is fed into a turbine hydrodynamic model to generate a synthetic loading regime which is then used in a Physics of Failure model to predict component Remaining Useful Life (RUL). The approach is demonstrated for the failure critical Pitch System (PS) bearing unit of a notional horizontal axis TST. It is anticipated that the approach developed here will enable device/project developers, technical consultants and third party certifiers to undertake robust reliability assessments both during turbine design and operational stages.ETIEngineering and Physical Sciences Research Council (EPSRC

    Student Classroom Misbehavior: An Exploratory Study Based on Teachers\u27 Perceptions

    This study aimed to examine the conceptions of junior secondary school student misbehaviors in classroom, and to identify the most common, disruptive, and unacceptable student problem behaviors from teachers\u27 perspective. Twelve individual interviews with teachers were conducted. A list of 17 student problem behaviors was generated. Results showed that the most common and disruptive problem behavior was talking out of turn, followed by nonattentiveness, daydreaming, and idleness. The most unacceptable problem behavior was disrespecting teachers in terms of disobedience and rudeness, followed by talking out of turn and verbal aggression. The findings revealed that teachers perceived student problem behaviors as those behaviors involving rule-breaking, violating the implicit norms or expectations, being inappropriate in the classroom settings and upsetting teaching and learning, which mainly required intervention from teachers

    The Project P.A.T.H.S. in Hong Kong—Lessons Learned and Implications for Positive Youth Development Programs

    Get PDF
    The Project P.A.T.H.S. is a positive youth development program which attempts to promote holistic development of junior secondary schools in Hong Kong. It is ground breaking in terms of the number of schools participating in the project and financial resources injected into the project. Based on the experiences gained from the implementation of the project and evaluation data collected from 2005 to 2011, several issues pertinent to the development of positive youth development programs in the Chinese culture are discussed. These issues include complexity of program development, importance of training, identification of factors governing program implementation, need for evaluation, and promotion of sustainability of the program in the long run

    Evaluation of the Project P.A.T.H.S. Based on Students' Weekly Diaries: Findings from Eight Datasets

    Get PDF
    This paper aims to investigate the effectiveness of the Tier 1 Program of the Project P.A.T.H.S. (positive adolescent training through holistic social programmes) based on eight datasets collected between 2005 and 2009. A total of 1,138 students who participated in the program were randomly invited (from the whole grade or in some classes) to write a piece of journal in the form of a weekly diary in order to reveal their perceptions and feelings regarding the program and the perceived benefits of the program. Based on an integration of findings from different databases, results showed that the respondents generally (1) had positive views on the program, (2) had positive views on the instructors, and (3) perceived that they had acquired competencies at the societal, school, familial, interpersonal, and personal levels after joining the program. Acknowledging the limitations of diaries, the present qualitative findings provide support for the effectiveness of the Tier 1 Program of the Project P.A.T.H.S. in Hong Kong
