The strategy of delinquency control : a critical survey of recent developments and a proposal for some local applications.
Creators: name: Liquornik, Israel
Publisher: name: University of British Columbia
Year: 2011

description: Although there are immense philosophical and technical difficulties in assessing the dimensions and severity of a social problem, there can be little doubt that juvenile delinquency is a proper subject of deep public concern. At the present time, however, few of the methods commonly employed in dealing with it appear to have more than a marginal effect on its ever-increasing prevalence. Part of this problem seems to be attributable to the heterogeneous and often contradictory character of the available etiologies of juvenile delinquency. But part also would appear to derive from the stereotyped reliance on a "case" approach to the phenomenon; an approach which, though legitimate and. even indispensable when some form of psychiatric abnormality is involved in the genesis of delinquent behavior, is manifestly inept when the problem has reached epidemic proportions. The aim of this study, therefore, is to examine a number of recent attempts - of both scientific and a practical nature-to formulate alternative arid demonstrably more effective techniques of solving or mitigating the problem of juvenile delinquency. In fact, many of the programs reviewed do give promise of an altogether higher level of usefulness than can be assigned to the methods which are currently favoured. The position is taken that juvenile delinquency can only be dealt with competently if the decisions underlying the employment of particular programs are based upon essentially strategic considerations of (a) the type of delinquency at Issue, (b) the nature of the causal factors predominating in its occurrence, and (c) the consequent differences in the aptness of the several alternative responses to the problem. The composition and condition of local correctional services are reviewed and evaluated in the light of this critical principle and are found to be alarmingly inadequate to its demands. It is argued that a region, such as British Columbia, which is in the convulsions of rapid social change, is under a particular necessity to anticipate and plan for its social problems with strategic breadth and intelligence.

description: Electron transport properties of a biphenyl molecule are studied based on the Green's function formalism. The molecule is sandwiched between two metallic electrodes, where each benzene ring is threaded by a magnetic flux $ϕ$. The results are focused on the effects of the molecule to electrode coupling strength and the magnetic flux $ϕ$. Our numerical study shows that, for a fixed molecular coupling, the current amplitude across the bridge can be {\em regulated} significantly just by tuning the flux $ϕ$. This aspect may be utilized in designing nano-scale electronic circuits.

title: Difficulty of Decision-Making by Widows
Creators: name: Noyes, Marilyn Bjorkman
Publisher: name: Utah State University
Year: 1971

description: The difficulty of decision - making by women who are widows compared to when they were wives was studied. The areas of decision-making that were rated as to difficult concerned family finance, child care, homemaking (family foods, clothing, home furnishings, and housing), social activities, and yard and car care.
The sample consisted of 33 widows living in Logan, Utah during Spring Quarter, 1971. The subjects had at least one child living at home and had been widowed at least one year.
The instruments used were: ( l) a background questionnaire, and (2) a decision-making questionnaire. The statistical test used for analysis was the sign (binomial) test.
Decisions concerning family finance, child care, cleaning and upkeep of the home, and yard care were more difficult for the women as widows than such decisions had been for them as wives.
Decisions concerning food, clothing, and home furnishings were not more difficult for the women as widows.
Decisions concerning washing the car were not more difficult, while decisions about maintenance, servicing, and repairs for the car were more difficult for the women as widows.
Decisions concerning social activities that are often done as individuals, not couples, were not more difficult for the women as widows. Decisions concerning those social activities that couples often participate in were more difficult for the women as widows than such decisions had been for them as wives.

title: The Ability of Young Children to Recognize Words
Creators: name: Armstrong, Katherine K.
Publisher: name: Utah State University
Year: 1971

description: The young child's ability to learn to read (defined in this study "to recognize") words was studied in an attempt to determine the influence of age.
Fourteen, three-year-old children and 16, four and one-half year old children, 14 girls and 16 boys, were instructed to read eight words. Groups of three were taught in four, ten minute sessions and were then tested one at a time for word recognition. A retention test was given two weeks later.
The hypotheses, that three-year-old children will learn to read more readily than children nearer five years old and that girls will read better than boys, were not confirmed. The four-year-old girls gained the highest scores and the four-year-olds learned an average of one more word than the three-year-olds but the differences were not significant.
It may be concluded that age and sex differences in ability to learn to read words appear to develop at a later age than three or four years. It appears, however, that learning to read words is not beyond the capabilities of three and four-year-old children.
Preferential attachment renders an evolving network of populations robust against crashes

description: We study a model for the evolution of chemical species under a combination of population dynamics on a short time scale and a selection mechanism on a longer time scale. Least fit nodes are replaced by new nodes whose links are attached to the nodes of the given network via preferential attachment. In contrast to a random attachment of newly incoming nodes that was used in previous work, this preferential attachment mechanism accelerates the generation of a so-called autocatalytic set after a start from a random geometry and the growth of this structure until it saturates in a stationary phase in which the whole system is an autocatalytic set. Moreover, the system in the stationary phase becomes much more stable against crashes in the population size as compared to random attachment. We explain in detail in terms of graph theoretical notions which structure of the resulting network is responsible for this stability. Essentially it is a very dense core with many loops and less nodes playing the role of a keystone that prevents the system against crashes almost completely.

Creators: name: Meals, Pamela
Publisher: name: Utah State University
Year: 1968

description: Attitudes of middle class mothers and fathers toward nursery school education were measured and compared. The subjects were parents of children who attended the Utah State University nursery school. A scale was developed to test parental attitudes. Attitudes toward nursery school education were definitely favorable. Comparison of attitudes expressed by mothers with those expressed by fathers revealed significant differences between the two groups, when the total number of responses of all scale items were considered together.
The total scale included 48 items comprising three subscales, which tested the following parental attitudes toward nursery school education: attitudes concerning a child's independence or dependence as it relates to nursery school attendance, attitudes pertaining to the value that the nursery school has for a child, and attitudes toward the care and guidance of a child while at nursery school . Comparisons of attitudes of mothers and fathers in each of these three areas disclosed that there was no significant difference between the two groups in attitudes expressed . Mean scores of mothers and fathers were 77.4 and 76.2, respectively.
The scale used to measure attitudes was found t o discriminate significantly between the high and low scoring subjects . However, an item analysis of the scale revealed few individual items which could discriminate significantly between the high and low scoring subjects.

Spectral States and Evolution of Ultraluminous X-ray Sources

Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)

description: We examined spectral evolution in ultraluminous X-ray sources (ULXs) with apparent luminosities of about 10^40 ergs/s. Based on new results in this paper and those reported in the literature, two common spectral behaviors were found. Some ULXs in starburst galaxies have varying luminosity (L) but remain in the hard state with power-law spectra and a constant, hard photon index (Gamma). Other ULXs, such as NGC 5204 X-1, show a correlation between L and Gamma. We interpret this L-Gamma correlated phase as an intermediate state with hybrid properties from the thermal dominant and steep power-law states. When the spectra of NGC 5204 X-1 are fitted with a multicolor disk blackbody plus power-law model, the X-ray luminosity increases with the effective temperature of the accretion disk in a manner similar to that found in stellar-mass black hole X-ray binaries, suggesting that the emission arises from an accretion disk. The luminosity, disk size, and temperature suggest that NGC 5204 X-1 harbors a compact object more massive than stellar-mass black holes. In contrast, the disk model in IC 342 X-1 is ruled out because the luminosity decreases as the temperature increases; sources with such behaviors may represent a class of objects with super-Eddington accretion. Also, we report a peculiar soft spectral feature from IC 342 X-2 and variability on a time scale of 20 ks from Holmberg II X-1. More observations are needed to test these results.

Strong-coupling Superconductivity in the Cuprate Oxide

Subjects: subject: Superconductivity (cond-mat.supr-con)

subject: FOS: Physical sciences

description: Superconductivity in the cuprate oxide is studied by Kondo-lattice theory based on the t-J model with the el-ph interaction arising from the modulation of the superexchange interaction by phonons. The self-energy of electrons is decomposed into the single-site and multisite ones. It is proved by using the mapping of the single-site one in the t-J model to its corresponding one in the Anderson model that the single-site self-energy is that of a normal Fermi liquid, even if a superconducting (SC) order parameter appears or the multisite one is anomalous. The electron liquid characterized by the single-site self-energy is a normal Fermi liquid. The Fermi liquid is further stabilized by the RVB mechanism. The stabilized Fermi liquid is a relevant unperturbed state that can be used to study superconductivity and anomalous Fermi-liquid behaviors. The so-called spin-fluctuation-mediated exchange interaction, which includes the superexchange interaction as a part, is the attractive interaction that binds d-wave Cooper pairs. An analysis of the spin susceptibility implies that, because of the el-ph interaction, the imaginary part of the exchange interaction has a sharp peak or dip at \pmω^*, where ω^*\simeq ω_ph in the normal state and ε_G/2 \lessim ω^* \lessim ε_G /2+ ω_ph in the SC state, where ω_ph is the energy of relevant phonons and ε_G is the SC gap. If the imaginary part has a sharp peak or dip at \pmω^*, the dispersion relation of quasi-particles has kink structures near \pmω^* above and below the chemical potential, the density of states has dip-and-hump structures near \pm ω^* outside the coherence peaks in the SC state, and the anisotropy of the gap deviates from the simple d-wave anisotropy.

title: The Preschool Child's Awareness of Body Structure in Sexual Differences
Creators: name: Anderson, Genan Taylor
Publisher: name: Utah State University
Year: 1969

description: The purpose was to discover whether the preschool child who has toileted with boys and girls in an open situation for at least four weeks would recognize the genital differences between a male and a female doll and use this knowledge to select the type of clothes appropriate for these dolls. Hypotheses were: (1) The preschool child who has toileted in an open situation with both sexes for at least four weeks can identify male and female dolls on the basis of genital structure. (2) The preschool child can select appropriate clothes for male and female dolls on the basis of genital structure as the dominant cue as to sexuality . Twenty children ages three to five were selected because they had toileted in an open situation for at least four weeks with boys and girls, because they attended the same classroom, and were familiar with the experimenter . Preceding the actual collection of data a pilot study was conducted on a similar but separate classroom of children to test the proposed research design. The subjects were informed, as a group, of the general content and procedure of the experimental situation to follow. The subjects went first behind the screen with the experimenter to arrange six blocks in any design they wished. They went again behind the screen in the doll house where they sat facing the genitals of a male and a female doll. After powdering the dolls' genitals, they selected clothes for them from two sets of male slacks and two dresses. The subject was then asked the reason for his choice. Four of the 20 subjects, two boys and two girls, were able to identify the sex of the dolls on the basis of genital structure. All four were from homes with opposite-sex siblings. Three of the four expressing a recognition were four years old . Conclusions: (l) Preschool children appear generally to be unable to identify sexuality on the basis of genital structure . (2) Age is a significant factor influencing the child's discrimination of sexual differences. (3) The opportunity for observation and discovery of differences between the sexes through the presence of opposite-sex siblings in the home appears to be influential on the child's development of sexual awareness.

description: DAOSPEC is a Fortran code for measuring equivalent widths of absorption lines in stellar spectra with minimal human involvement. It works with standard FITS format files and it is designed for use with high resolution (R>15000) and high signal-to-noise-ratio (S/N>30) spectra that have been binned on a linear wavelength scale. First, we review the analysis procedures that are usually employed in the literature. Next, we discuss the principles underlying DAOSPEC and point out similarities and differences with respect to conventional measurement techniques. Then experiments with artificial and real spectra are discussed to illustrate the capabilities and limitations of DAOSPEC, with special attention given to the issues of continuum placement; radial velocities; and the effects of strong lines and line crowding. Finally, quantitative comparisons with other codes and with results from the literature are also presented.

title: Marriage Role Perceptions of Husbands and Wives Separated by the Vietnam War
Creators: name: Bentson, Ella Arlene
Publisher: name: Utah State University
Year: 1969

description: The purpose was to determine how husbands and wives who had been separated because of the war in Vietnam perceived each other during separation. Martial roles were used as the vehicle to convey perception.
A random sample of Jl couples was selected from among the married officers and enlisted men of Marine All Weather Attack Squadron 225 which was based at DaNang, South Vietnam. A questionnaire designed to determine perception of spouse was sent to men in Vietnam and to their wives who resided in various parts of the United States.
The major findings are summarized as follows:
l. Correlation of roles ranked in order of importance before and after separation by respondents was significant at or beyond the .05 level for all roles except that of mother. This indicates that there was really very little change in the importance of roles during separation. Tne mother role was most variable.
2. Husbands were significantly more accurate than wives in duplicating the ranking of roles by spouse.
3. Both husbands and wives were significantly more accurate predicting the role ranking of the other before separation than they were in predicting how the other would rank his roles after separation.
4. Wives were more congruent than husbands in perception of the spouse in roles they ranked as being highly important for the spouse.
5. Men who had children tended to be congruent between thought patterns about their wives and the roles they ranked as important for them. They usually ranked the roles of wife and mother high and often thought of their wives in these roles. This congruency did not exist with the men who had no children.
6 . There was significantly greater marital satisfaction before separation.
7. Perception of very high marital satisfaction after separation indicates that ideolization or glossing of the absent situation and absent person occurred.
title: Attitudes Toward Creativity of Day Care Teachers and College Nursery School Teachers
Creators: name: Bishop, Bonnie Kay Magleby
Publisher: name: Utah State University
Year: 1969

description: Previous studies have indicated the importance of teacher attitudes on the development of creativity in children. There were several purposes for this investigation. The major purpose was to develop an instrument to measure teacher attitudes toward creativity in children. The second step was the utilization of the instrument to determine if teachers trained in child development are more positive in their attitudes toward creativity than teachers with little or no background in child development. The third purpose of this investigation was to determine the relations hip between the teachers' attitudes toward creativity and religion, age, and social class .
The creative attitude instrument was developed by the investigator using the method employed by Shoben in devising the University of Southern California Parent Attitude Survey. The instrument, composed of 83 items, was then administered by mail to day care owners and operators, who were licensed by the state of Utah during the summer of 1967, and to all college nursery school teachers employed during the school year of 1967-68 in the state of Utah. The teachers were asked to respond to each item, indicating whether they Strongly Agreed, Agreed, Disagreed, or Strongly Disagreed with the statement. The answers we re rated one to four, with four being the most positive of the responses.
The results indicated that there was no significant relationship between a teacher's attitude toward creativity and her age or social class. The results also indicated there was no significant difference between the attitudes toward creativity of day care and college nursery school teachers.
Although there was not a statistically significant difference between the attitudes of the college nursery school teachers and the day care teachers toward creativity on this instrument, the nursery school teachers gave more favorable responses to 13 of the 16 discriminating items found on the instrument.

Year: 2011

description: The present study is, in part, a description of meristic variation in the pygmy whitefish, Prosopium coulteri, of British Columbia fish with those of other areas. The species was shown to be highly variable meristically both within and between populations. There are indications in some characters of a north-south cline of meristic counts. One character (gill raker counts) seems to form a V-shaped curve of variation. The major part of the study is a comparison of the growth and relative growth of fish from four British Columbia lakes. The two "giant" forms from MacLure and McLeese Lakes are more like one another in relative growth than like either of the two dwarf forms inhabiting Cluculz Lake or Tacheeda Lake. The possible relationship between growth, form and environment is discussed.
An estimating equations approach to fitting latent exposure models with longitudinal health outcomes

description: The analysis of data arising from environmental health studies which collect a large number of measures of exposure can benefit from using latent variable models to summarize exposure information. However, difficulties with estimation of model parameters may arise since existing fitting procedures for linear latent variable models require correctly specified residual variance structures for unbiased estimation of regression parameters quantifying the association between (latent) exposure and health outcomes. We propose an estimating equations approach for latent exposure models with longitudinal health outcomes which is robust to misspecification of the outcome variance. We show that compared to maximum likelihood, the loss of efficiency of the proposed method is relatively small when the model is correctly specified. The proposed equations formalize the ad-hoc regression on factor scores procedure, and generalize regression calibration. We propose two weighting schemes for the equations, and compare their efficiency. We apply this method to a study of the effects of in-utero lead exposure on child development.

description: Purpose: In the tradition of Spencer Brown's (1969) Laws of Form, observation was defined in Luhmann's (1984) social systems theory as the designation of a distinction. In the sociological design, however, the designation specifies only a category for the observation. The distinction between observation and expectation enables the sociologist to appreciate the processing of meaning in social systems. Design: The specification of "the observer" in the tradition of systems theory is analyzed in historical detail. Inconsistencies and differences in perspectives are explicated, and the specificity of human language is further specified. The processing of meaning in social systems adds another layer to the communication. Findings: Reflexivity about the different perspectives of participant observers and an external observer is fundamental to the sociological discourse. The ranges of possible observations from different perspectives can be considered as second-order observations or equivalently as the specification of an uncertainty in the observations. This specification of an uncertainty provides us with an expectation. The expectation can be provided with (one or more) values by observations. The significance of observations can be tested when the expectations are properly specified.
title: The Effect of Nursery School Experience Upon Readiness of Children in Kindergarten
Creators: name: Boyce, Glenna C.
Publisher: name: Utah State University
Year: 1969

description: The Metropolitan Readiness Test, 1964 edition, Form A, was administered to forty children who were enrolled in kindergarten classes in Logan, Utah, during the school year 1967-1968. Twenty of these children (nursery attenders) had attended the Utah State University Child Development Laboratory for at least two, but not more than three quarters with at l east half of this nursery experience being during the year preceding kindergarten. The other 20 children (non-attenders) had not experienced any type of pre-school or day care program prior to kindergarten. The two groups were matched by pairs on age, sex, kindergarten teacher and socio-economic level of the father. The sample of 40 included 12 pairs of boys and eight pairs of girls.
The primary null hypothesis was rejected because the nursery attenders did significantly better (to the .05 level) on the Metropolitan Readiness Test than the non-attenders. In analyzing this result, sex was found to be an important variable. The boy nursery school attenders did significantly better (to the .01 level) than the boy nonattenders on the Metropolitan Readiness Test. There was no significant difference between the scores of the girl nursery attenders and the girl non-attenders although the nursery attenders tended to score higher on the Metropolitan Readiness Test.
However, the secondary null hypothesis was held tenable. The variables of mother's education, mother working outside of home, number of children in family and birth order position were not found to be significantly related to readiness.

description: In this work we demonstrate both experimentally and theoretically that the analog noise generation by a single enzymatic logic gate can be dramatically reduced to yield gate operation with virtually no input noise amplification. This is achieved by exploiting the enzyme's specificity when using a co-substrate that has a much lower affinity than the primary substrate. Under these conditions, we obtain a negligible increase in the noise output from the logic gate as compared to the input noise level. Experimental realizations of the AND logic gate with the enzyme horseradish peroxidase using hydrogen peroxide and two different co-substrates, 2,2'-azino-bis(3-ethylbenzthiazoline-6-sulphonic acid) (ABTS) and ferrocyanide, with vastly different rate constants confirmed our general theoretical conclusions.

description: We explored the impact a new quantitative biology course for biology majors had on their ability and confidence to utilize hypothesis testing. Students currently in the quantitative biology course and the first cohort of students who took the course (currently seniors) were surveyed on ability and confidence regarding four types of hypothesis testing. Overall student confidence increased for when and why to perform t-tests following the course, and improvement with t-tests and analysis of variance continued for seniors. Incorporation of a quantitative biology course into the curriculum for biology majors provides students with the opportunity to apply statistical methods to real-world biological situations.

description: New robotic lunar landings may take place during next decade. The Italian Space Agency (ASI) has requested proposals for interesting and compelling physics experiments to be performed with the severe weight, size, power and deployment restrictions inherent to lunar sorties. MoonLIGHT-R is a proposal for improving by a factor 1000 or more the accuracy of the current Lunar Laser Ranging (LLR) experiment, performed since 1969 with retro-reflector arrays deployed by Apollo 11, 14 and 15. LLR is the only Apollo experiment still taking data today. Achieving this goal requires a new, different thermal, optical and mechanical design of the retro-reflector array and detailed simulations and experimental tests. MoonLIGHT-R is a light, compact, very-long lasting, maintenance-free and completely passive payload. MoonLIGHT-R will perform accurate tests of General Relativity (GR) already with the existing ILRS systems (like ASI-MLRO) . This accuracy will get better and better as laser technologies improve over the next few decades, like they did relentlessly since the invention of the laser in the '60s. A specific cosmological model, which explains the acceleration of the Universe via modified GR at very large distances, can be fully tested by measuring an anomalous precession of the Moon perigee. A high scientific return is guaranteed. We are committed to the space-climatic and laser-optical simulation (and, at a later stage, experimental characterization) of the new LLR array using the LNF Space Climatic Facility (SCF). The payload construction and deployment is an opportunity for the national industries. Preliminary space-climatic simulations and payload specs are presented in this LNF report.

description: The introduction of contemporary music to elementary and junior high school students in performance classes is hindered by a shortage of such music playable by young students. For example, in Contemporary Music for the Schools (Music Educators National Conference, 1966) which is the major source of contemporary music for school bands, 85 band pieces are listed, but only five are designated as suitable for junior high school bands, and only two are designated as suitable for elementary school bands.
In this project, five original band pieces (Bodo, Whispers and Shouts, Malcolm, Fission and Fusion, Newton's Number Three,) of a difficulty playable by elementary and junior high school bands and coordinated with representative elementary band method books, were composed to be used to develop in young instrumentalists an understanding of the following aspects of contemporary music through performance: quartal harmony; large and small cluster harmonies; hi-tonality; the Twelve-Tone Technique; mild dissonance, severe tonal dissonance, several atonal dissonance, severe atonal dissonance emphasizing "white sound" or "noise" rather than specific pitch, and severe dissonance caused by partially random clashes of independent groups in different tonalities; frequent meter changes; abrupt treatment of rhythms and phrase endings; simultaneous playing of two and three groups independent of each other in thematic material, meter, tempo, character, tonality and instrumentation; phrases with two-measure basic substructure contrasted with phrases with three-measure basic substructure; asymmetrical phrase lengths; melodies doubled at the interval of a second or seventh; and abrupt, fragmented melodic elements.
Introductory material to each piece, including technical requirements for performance, struc tura 1 ana lysis, suggestions for performance, and an "Introducing the Music" section found also in the students' books were included to complete a Method for Young Bands intended to supplement regular band materials. Suggestions to teachers for the use of the Method were also included.

title: The Attitudes of Blue Collar Adolescents Towards Employment of Women and Child Rearing Practices
Creators: name: Morgan, Blain Richard
Publisher: name: Utah State University
Year: 1970

description: Purpose was to collect and sample the attitudes of "blue collar" adolescents toward the employment of women and child rearing practices. Data were from 304 adolescents whose father s fit the requirements of being "blue collar." A questionnaire was administered that asked for attitudes and reactions to questions related to the employment of a woman through the normal stages of a family cycle and for attitudes related to child rearing practices.
The attitudes of the "blue collar" adolescents were then compared to findings recorded in a similar study that dealt with the attitudes of rural adolescents toward the employment of women. It was hypothesized that attitudes toward the employment of women would be influenced by the age and sex of the adolescents of the ''blue collar" family; that the attitudes of the adolescent would be influenced by t he occupation and employment history of his mother and that the attitudes of the adolescents from the "blue collar" family would be different from those of adolescents in a rural environment. The hypotheses were supported by the data from this study. With respect to child rearing practices, the females have much more positive attitudes toward child rearing practices than was true of the males.

description: Uniform spanning trees on finite graphs and their analogues on infinite graphs are a well-studied area. On a Cayley graph of a group, we show that they are related to the first $\ell^2$-Betti number of the group. Our main aim, however, is to present the basic elements of a higher-dimensional analogue on finite and infinite CW-complexes, which relate to the higher $\ell^2$-Betti numbers. One consequence is a uniform isoperimetric inequality extending work of Lyons, Pichot, and Vassout. We also present an enumeration similar to recent work of Duval, Klivans, and Martin.

title: Effects of Sensori-Motor Reinforcement on Alphabet Letter Discrimination Tasks
Creators: name: Peters, Leona Magnus
Publisher: name: Utah State University
Year: 1970

description: Recent research studies indicate the importance of sensory input in the development of perceptual skills. Learning the alphabet, an abstract symbol system, is considered a perceptual task. The major purpose of this investigation was to determine the effect of a visual experience reinforced by a sensori-motor experience in improving the ability of kindergarten pupils to perceive the configuration of alphabet letters and the order of these letters in a word.
Two separate kindergarten classes were selected as the experimental and control groups. The learning task was individualized through the use of each subject's own name.
Each subject in both groups was provided a daily visual perceptual experience with his own name through the use of a visual model card. In addition, each school day during the twelve day program, the experimental group received approximately five minutes of sensori-motor experience with the alphabet letters in their own names to tactfully reinforce the visual experience.
The results of the data collected indicate that the Ss in the experimental group showed greater improvement scores than the control group. On the positioning task, the experimental group showed a 6. 3 per cent greater improvement score at level I and a 8. 3 per cent greater improvement score at level II. On the ordering task, the experimental group showed a 13 .9 per cent greater improvement score at level I and a 30. 6 per cent greater improvement score at level II. Subjects performing at level I worked with their first names and subjects performing at level II worked with their first and last names.
The hypotheses were supported. The use of three dimensional moveable alphabet letters to build their own names increased the subjects perception of these abstract symbols through increased visual tactual sensory input.

description: The integration of biology with mathematics and computer science mandates the training of students capable of comfortably navigating among these fields. We address this formidable pedagogical challenge with the creation of transdisciplinary modules that guide students toward solving realistic problems with methods from different disciplines. Knowledge is gradually integrated as the same topic is revisited in biology, mathematics, and computer science courses. We illustrate this process with a module on the homeostasis and dynamic regulation of red blood cell production, which was first implemented in an introductory biology course and will be revisited in the mathematics and computer science curricula.

description: Let S be a Sobolev or Orlicz-Sobolev space of functions not necessarily vanishing at the boundary of the domain. We give sufficient conditions on a nonnegative function in S in order that its spherical rearrangement ("Schwartz symmetrization") still belongs to S. These results are obtained via relative isoperimetric inequalities and somewhat generalize a well-known Polya-Szego's theorem. We also prove that the rearrangement of any function in S is locally in S.

description: We studied the performances of the underwater neutrino telescope NEMO-KM3 equipped with direction-sensitive optical modules.  The main feature of these optical modules is to detect the direction of the incoming Cherenkov light. In this note we show that the effective area of the underwater neutrino telescope NEMO-KM3 could be improved at low neutrino energies (E_nu < 10 TeV) by adding in the reconstruction procedure the information on the direction of the detected Cherenkov light. As a consequence we show that it is possibile to reduce the number of towers from 81 to 64 maintaining the same effective area of NEMO-KM3.
title: A Comparative Study of the Goals of Middle-Aged Student and Non-Student Homemakers
Creators: name: Buttars, Ann
Publisher: name: Utah State University
Year: 1977

description: This study compared the goals of middle-aged student and non-student homemakers. Achieved, current and future goals were investigated.
The student sample was composed of twenty-five married , female, full-time students between the ages of thirty and fifty enrolled at Utah State University and was matched with a non-student sample as closely as possible. At least one full year of college had been attained by all subjects before marriage.
Data were collected through interviews conducted by the researcher during fall quarter, 1973. A non-directional t test was used to analyze the differences be tween the number of goals identified by both samples. Three hypotheses were tested. Analysis of the results failed to prove their validity, therefore, they could not be accepted.
When the goals of the two groups of women were compared, few differences were found. Family goals were unanimously ranked as most important by both samples for all areas studied. Throughout this study the non-student sample seemed to have more goals, although not a significant difference, and to hold more conventional attitudes regarding the goals and roles of women than the student sample.
