The Change Agent of the Fishermen Development Area Staff of the Fisheries Development Authority of Malaysia

This study was conducted primarily to assess the change agent roles of the Fishermen Development Area (FDA) staff of the Fisheries Development Authority of Malaysia (LKIM). Data for this study were gathered from 59 FDA frontline officers from five selected FDAs through group self-administered questionnaires and drop-and-collect data collection method. The study revealed that majority of the respondents were 30 years old and below; majority of them completed the Cambridge Overseas School Certificate/Malaysian School Certificate; nine were Diploma and Bachelor's Degree holders and majority of them joined LKIM without any working experience. With regard to role performance of the FDA staff contacted, the study revealed that almost all of the respondents did not consider work planning as part of their responsibility; more than three-fourths consulted their state supervisors as need arises; more respondents were dissatisfied than satisfied with their job; and slightly more than three-fourths of the respondents had linkage with staff from other agencies (mainly through meetings/conferences/workshops attended). Both the assistant development officers and the development assistants found it either very difficult or not difficult at all working with the fishermen. The managers were very certain of their felt difficulties both in working with the fishermen and with colleagues/supervisors and staff from other agencies. Generally, there seemed to be lack of clear understanding of change agent's role among the respondents. Based on selected personal characteristics, the mental and experiential preparation of the staff seemed to be inadequate for the officers to carry rut their expected change agent roles. Further preparation is needed for IKIM to help its staff to be more process-oriented

Exponential Chain Dual to Ratio cum Dual to Product Estimator for Finite Population Mean in Double Sampling Scheme

This paper considers an exponential chain dual to ratio cum dual to product estimator for estimating finite population mean using two auxiliary variables in double sampling scheme when the information on another additional auxiliary variable is available along with the main auxiliary variable. The expressions for bias and mean square error of the asymptotically optimum estimator are identified in two different cases. The optimum value of the first phase and second phase sample size has been obtained for the fixed cost of survey. To illustrate the results, theoretical and empirical studies have also been carried out to judge the merits of the suggested estimator with respect to strategies which utilized the information on two auxiliary variables

Minority-carrier lifetime in InP as a function of light bias

Minority-carrier lifetime in InP is studied as a function of doping level and laser intensity using time-resolved photoluminescence. A continuous wave diode laser illuminates bulk InP and acts as a light bias, injecting a steady-state concentration of carriers. A 200 ps laser pulse produces a small transient signal on top of the steady-state luminescence, allowing lifetime to be measured directly as a function of incident intensity. For p-InP, lifetime increases with light bias up to a maximum value. Bulk recombination centers are presumably filled to saturation, allowing minority carriers to live longer. The saturation bias scales with dopant concentration for a particular dopant species. As light bias is increased for n-InP, minority-carrier lifetime increases slightly but then decreases, suggesting radiative recombination as a dominant decay mechanism

Pulsed laser illumination of photovoltaic cells

In future space missions, free electron lasers (FEL) may be used to illuminate photovoltaic receivers to provide remote power. Both the radio-frequency (RF) and induction FEL produce pulsed rather than continuous output. In this work we investigate cell response to pulsed laser light which simulates the RF FEL format. The results indicate that if the pulse repetition is high, cell efficiencies are only slightly reduced compared to constant illumination at the same wavelength. The frequency response of the cells is weak, with both voltage and current outputs essentially dc in nature. Comparison with previous experiments indicates that the RF FEL pulse format yields more efficient photovoltaic conversion than does an induction FEL format

Space-time evolution of electron cascades in diamond

Here we describe model calculations to follow the spatio-temporal evolution of secondary electron cascades in diamond. The band structure of the insulator has been explicitly incorporated into the calculations as it affects ionizations from the valence band. A Monte-Carlo model was constructed to describe the path of electrons following the impact of a single electron of energy E 250 eV. The results show the evolution of the secondary electron cascades in terms of the number of electrons liberated, the spatial distribution of these electrons, and the energy distribution among the electrons as a function of time. The predicted ionization rates (5-13 electrons in 100 fs) lie within the limits given by experiments and phenomenological models. Calculation of the local electron density and the corresponding Debye length shows that the latter is systematically larger than the radius of the electron cloud. This means that the electron gas generated does not represent a plasma in a single impact cascade triggered by an electron of E 250 eV energy. This is important as it justifies the independent-electron approximation used in the model. At 1 fs, the (average) spatial distribution of secondary electrons is anisotropic with the electron cloud elongated in the direction of the primary impact. The maximal radius of the cascade is about 50 A at this time. As the system cools, energy is distributed more equally, and the spatial distribution of the electron cloud becomes isotropic. At 90 fs maximal radius is about 150 A. The Monte-Carlo model described here could be adopted for the investigation of radiation damage in other insulators and has implications for planned experiments with intense femtosecond X-ray sources.Comment: 26 pages, latex, 13 figure

Evaluation of indoor aerosol control devices and their effects on radon progeny concentrations

Eleven portable air cleaning devices have been evaluated for control of indoor concentrations of respirable particles, and their concomitant effects on radon progeny concentrations have been investigated. Of the devices we examined the electrostatic precipitators and extended surface filters had significant particle removal rates, while the particle removal rates for several small panel-filters, an ion-generator, and a pair of mixing fans were found to be negligible. The evaluation of radon progeny control produced similar results; the air cleaners which were effective in removing particles were also effective in reducing radon progeny concentrations. Furthermore, at the low particle concentrations, plateout of the unattached radon progeny was found to be a significant removal mechanism. The overall removal rates due to deposition of attached and unattached progeny have been estimated from these data, and the equilibrium factors for total and unattached progeny concentrations have been calculated as a function of particle concentration. 7 references, 2 figures

1946: Abilene Christian College Bible Lectures - Full Text

Abilene Christian College Lectures - 1946 INTRODUCTION It has been our purpose at Abilene Christian College down through the years to provide in the Annual Bible Lectureship programs that which would be appropriate for the time and most useful to the students and to the Lectureship visitors. The general subject for the 1946 lectures is “Things That Cannot Be Shaken.” This subject was selected because one of the battles, if not the battle, which the church faces today is against those forces which would undermine the bases of gospel truth. Many denominational leaders, in one way or another, are denying even the fundamentals of fundamentals— God is, the Bible is God\u27s Revelation, Jesus Christ is the Son of God and The Kingdom Cannot Be Shaken. Many others, some without knowing what they do, are accepting false teachings and ideologies which, if allowed to run their course, will destroy all true religion. It is believed that the 1946 lectures and this edition of the lectures will help toward establishing in the hearts of men the truth of the important theses discussed. It was the purpose of those who arranged the program that the Lectureship should, also, hold up Christianity as a working, practical religion; hence, the meetings on “Work in New Fields” and “The Church at Work.” The attendance of this Lectureship was the largest in the history of these yearly meetings. On Wednesday evening Brother Nichol spoke to a crowd of approximately 1700 persons. Other evening lectures were attended by crowds almost as large. Visitors came from more than a score of States and, also, from Canada and Mexico. It is the hope of all of us at the College that the fellowship of the 1946 Lectureship and the instruction given by the various speakers will continue to do good for years without end. DON H. MORRIS
