    Women's Domestic Power: A Study of Women's Roles in A Tunisian Town

    No full text
    The study of women's roles in the Tunisian town of Ksar-Hellal was predicated on the assumption that the women of a society have different cultural perspectives from those of men. This is particularly significant in an Islamic society, since such societies traditionally require a social separation of men's and women's activities. Since the concern of this study is to understand the lives of women, a detailed analysis of the daily activities and interests of women serves as a framework for examining women's power. Men are to some extent shadow figures in this work, just as women are in a number of other ethnographic accounts.For the women of Ksar-Hellal, the domestic sector of the community, the family and household comprises the main sphere of interaction. While many anthropological studies have emphasized the significance of the domestic group as a social unit of primary importance, there are few detailed studies of the interactional patterns within the domestic sector. This study of Ksar-Hellal women provides insights into the operations of the domestic unit. The domestic unit is significant to women because it is an area in which they have considerable control over valued actions, resources and social relationships. The domestic unit represents a base of power for the women of this community.While women's power in the domestic unit has frequently been hinted at in ethnographic accounts, there are few detailed analyses of the actual processes by which women exert power. The study of women's domestic power in Ksar-Hellal focuses on defining the strategies and decision-making of women in specific social situations as a means of delineating women's mechanisms of power and the ways in which this power is operationalized. This interactional framework presents an analysis of power from an individual perspective, rather than from a social organizational point of view.The case study of women's domestic power in Ksar-Hellal illustrates the potential for women to exert influence over a wide range of community actions. Women exert economic control through the management and processing of household resources, as well as utilizing their own financial resources to influence a variety of social situations both within and outside of the household. Through their major role in socializing children, as well as managing household affairs, women have a significant influence over family relationships. The network of women's relationships in the community provides an important source of communication and acts as a mechanism for social control over individual behavior. Through their power within the household and the women's network, women in Ksar-Hellal have a significant influence over a number of community social patterns, including residence and marriage patterns and the community's occupational structure.Made available in DSpace on 2014-12-14T05:35:24Z (GMT).

    An Investigation of Reading Instruction, Effective Teaching Patterns, and Perceptions of Fourth-Grade Teachers and Their Pupils

    No full text
    This study examined the differences in reading instructional behavior for a random sample of 12 fourth-grade teachers and its effects on the pupils' perceptions of the teaching-learning process, recreational reading habits, and attitudes toward reading.The teachers were divided into three groups--"excellent," "good," and "average"--based on the rating of their respective administrators. An observation instrument, which was modified from the Anderson, Evertson, and Brophy model (1979), was used to record reading instructional behavior for each of the 12 teachers who were observed by the investigator and an assistant five times during one semester. Pupils of the 12 teachers were pre- and posttested with the reading subtest of the Wide Range Achievement Test, and were also administered a 26-item questionnaire which provided information relative to the pupils' recreational reading habits, perceptions of the teaching-learning situation, and attitudes toward reading. Teachers were also interviewed concerning the strategies they utilized to teach reading, their inservice needs, and their pupils' progress in reading.Although the pupils of "good" teachers outperformed the pupils of "excellent" and "average" teachers on a few variables, the following findings were reported: (1) There was no significant difference in the instructional behaviors of the three groups of teachers. (2) There was no significant difference among teachers based on ratings of principals and the performance of pupils on reading achievement tests. (3) There was no significant difference in the degree of teachers' adherence to the instructional model and their pupils' gains in reading achievement. (4) There was no significant difference among teachers for instructional time spent on reading. (5) There was no significant difference in teachers relative to pupils' perceptions of the teaching-learning process, reading habits at school and at home, and boys' and girls' attitudes toward reading.The principals' classifications of teachers is suspect, and teachers' observed behaviors are not highly correlated to their pupils' reading achievement gains.Made available in DSpace on 2014-12-15T18:50:51Z (GMT).

    Page Indexing for Textual Information Retrieval Systems

    No full text
    A number of applications exist for systems which can store and interactively retrieve from very large natural language textual databases. This thesis discusses conventional approaches to the design of such systems. The notion of page indexing is introduced as a new scheme for doing information retrieval from natural language full-text databases.The structure of a page indexed database is described and the algorithms needed to do retrieval using the page index are presented. Some characteristics of page indexed text are analyzed and measured in order to estimate the size of the page index, and to show how the size of the index is related to the page size. One of the advantages of the page indexing scheme is the ease with which such a system can be analyzed. This analysis is based on characteristics of the hardware used to implement the system and on characteristics of queries. Finally, three hypothetical systems are proposed and analyzed using the techniques and methodologies developed in this thesis. These systems range from a microprocessor for a database of 250 megabytes to a large computer system employing multiple special purpose processors for a database of 50 gigabytes.Made available in DSpace on 2014-12-15T19:25:29Z (GMT).

    Modifications of Small-Farmer Credit in the Maisan 77 Program of the Philippines

    No full text
    This study was conducted to determine possible reforms that may improve the Maisan 77 credit program. Specifically, it aimed to pinpoint suggestions that will reduce the net costs of lending and improve the financial and economic well-being of farmer-borrowers.To accomplish these objectives, survey data were used to specify and validate a liquidity-specified linear programming (LS-LP) model. Simulations of the model were made with variations in: (1) interest rate, (2) credit limit, and (3) mode of loan disbursement. The effects of a "break-even" rate of interest was given special focus since this is the rate of interest at which the credit program recovers its lending costs.The results of the simulations showed that:(1) The welfare losses of the farmer due to increases in interest rates can be offset by coordinated increases in the size of loan, thus, making the credit limit as more important to the farmer's well-being than the rate of interest he has to pay.(2) Disbursement of program loans in cash only resulted in improved financial structure and liquidity reservations for the farmer. The objective function, net cash flow and cash available increased. Reserved cash decreased while total reserved credit increased. These indicate that credit reservation tends to substitute for cash, allowing the farmer to commit more of his cash to production. A likely consequence is the possible extended outreach of the program to small farmers who have not yet been served with loans.Cash only disbursement of loan relaxes the restriction on its use. A more versatile loan like moneylender funds will be valued highly. Thus, higher valuation of cash program loan may lead the borrower to preserve such loan--and to protect it by paying back his/her debt.(3) The effect of break-even interest rate just by itself, is a general reduction in the farmer's welfare, though the lender recovers its lending costs. However, when coupled with increasing credit limit and an all cash disbursement of loan, results showed improvement in the well-being and liquidity position of the farmer as well.Using simple calculations, it was shown that the public sector's net cost of lending can be reduced by simultaneous increases in interest rate and credit limit.Made available in DSpace on 2014-12-15T20:28:51Z (GMT).

    Phase Transitions in Disordered Systems: I. Exciton/electron-Hole Liquid/plasma System in Germanium and Ii. Amorphous Ferromagnets and Spin Glasses

    No full text
    In Part I of this thesis, we present experimental evidence demonstrating that a metal-insulator (M-I) phase transition can occur separately from the liquid-gas (L-G) transition in the exciton/electron-hole (e-h) gas/e-h liquid system in stressed Ge. Using a strain well to confine the photoexcited carriers, we analyzed the spectral content and spatial distribution of e-h recombination luminescence. We observe a line of first-order transitions between the exciton gas and e-h gas occurring up to 7 K which we associate with the M-I transition. This is well above the temperature of the L-G critical point which we found to be 4.5 (+OR-) 0.5 K with a critical density of 3 (+OR-) 1 x 10('16) cm. Spectroscopic evidence is also presented for a triple point which we estimate to be about 4 K. At this temperature, we were able to fit our measured luminescence spectra at particular photoexcitation powers only by including a theoretical line shape for the e-h gas with a density of 2.0 (+OR-) .5 x 10('16) cm('-3). A simple expansion of the free energy of the e-h system is presented from which we calculate a critical temperature for the M-I transition of 5.4 K which, possible because of quantum effects, is substantially below our measured value. Lifetime measurements of the different phases of the e-h system are also made. In particular, we have measured an extremely long lifetime of 1.5 ms for strain-confined excitons below 3.2 K. This compares favorably with our predicted radiative lifetime of 2.0 ms in stressed Ge. Above 3.2 K, a rapid decrease in the exciton lifetime is observed with increasing temperature, concurrent with an exponential decrease in the observed luminescence intensity. Three models for thermally-activated loss of strain-confined excitons are considered as possible explanations.In Part II of this thesis, we obtain the thermodynamic properties of a system of Ising spins interacting with various random potentials in the Bethe-Peierls-Weiss (BPW) approximation. When the effective number of neighbors z approaches infinity, we show that all the magnetic properties arising from a BPW approximation, the mean-random-field (MRF) and the Sherrington-Kirkpatrick (SK) replica treatment are identical. Also, the microscopic internal energy in the BPW method can be integrated appropriately to obtain a microscopic free energy which is identical to that derived by diagrammatic expansions of the disordered Hamiltonian. Using this free energy and our calculated distribution of internal fields, we show that the BPW method reproduces all the results of SK including a negative entropy of -k/(2(pi)) at T = 0. We also show by analytical means that a square hole or gap arises in the low-temperature distribution of the single-particle excitation fields h(,0) at h(,0) = 0 in the limit of infinite z. In an externally applied field, the hole remains centered about the zero value of the total (internal plus external) field. The reasons for the unphysical low-temperature results occurring in both the SK and BPW treatments are clarified in our discussion of this gap. The phase diagram as a function of z is calculated within the MRF approximation. We find that for z > 8 the phase diagram is already very close to that of the infinite z case. Finally, we compare magnetization versus temperature curves which have been calculated within Handrich's approach with those calculated within the BPW approach in the limit of infinite z. The two approximations are very similar for small amounts of disorder but Handrich's method breaks down as the amount of disorder approaches the spin-glas boundary.Made available in DSpace on 2015-05-13T15:22:26Z (GMT).

    Hilbert -Huang -Transform Based Modelling and Simulation of Nonstationary Processes and Applications to Earthquake Engineering

    No full text
    The methods are further applied to generation of Uniform Hazard Earthquake Response Spectrum and Ground Motions. A record-based methodology is proposed and demonstrated by an example at Los Angeles. The resulting UHRS compare well with those of USGS and SAC. The method does not rely on theories or empirical models, such as the rupture models, attenuation relation, Fourier spectrum and it preserves the variability across the ensemble. It uses only free-field records from the local region with similar seismicity environment and does not scale the records, consequently, the UHGM are truly site-dependent. It considers the strikes of the major faults near the site and the difference between the fault normal and fault parallel directions, and provides UHRS and three-component UHGM in three orthogonal directions.Made available in DSpace on 2015-09-25T21:03:47Z (GMT).

    Predictors of Client Resistance in the Counseling Interaction

    No full text
    This counseling process study examines the first order relationship between therapist directive behavior as antecedent and client resistance as consequent for a single midtreatment session of 18 counseling dyads. Further considered are two proposed sources of variance (psychological reactance and satisfaction) for the association between therapist directive behavior and client resistance. Speaking turns were coded and finally represented according to dichotomous categories for therapist and client behavior, and 18 (one for each dyad) first order 2 x 2 behavior transition matrices. Analyses of these tables reveals an overall trend with therapist directive behavior slightly increasing the probability of client resistance across dyads. Considerable variation between dyads, on this relationship, was found to be related to both client reactance level and satisfaction. The predicted relation for reactance level and resistance was found to hold for satisfied, but not less satisfied clients. For satisfied clients, increases in reactance level corresponded to higher probabilities for resistance following directives. Less satisfied clients had consistently high probabilities for resistance following directives. Some support for an interaction effect was found with satisfaction explaining more variance for low reactance level clients then high reactance level clients. The implications of these findings are discussed with respect to research and practice. In particular, the findings suggest a need to consider resistance in an interactional and relational context.Made available in DSpace on 2015-09-25T19:55:45Z (GMT).
