description: Establishing or ruling out, either through solid mass measurements or upper limits, the presence of intermediate-mass black holes (IMBHs) at the centers of star clusters would profoundly impact our understanding of problems ranging from the formation and long-term dynamical evolution of stellar systems, to the nature of the seeds and the growth mechanisms of supermassive black holes. While there are sound theoretical arguments both for and against their presence in today's clusters, observational studies have so far not yielded truly conclusive IMBH detections nor upper limits. We argue that the most promising approach to solving this issue is provided by the combination of measurements of the proper motions of stars at the centers of Galactic globular clusters and dynamical models able to take full advantage of this type of data set. We present a program based on HST observations and recently developed tools for dynamical analysis designed to do just that.

description: (Abridged) We have obtained new spectrophotometric data for 28 HII regions in the spiral galaxy NGC 300, a member of the nearby Sculptor Group. The detection of auroral lines, including [OIII]4363, [SIII]6312 and [NII]5755, has allowed us to measure electron temperatures and direct chemical abundances for the whole sample. We determine for the first time in this galaxy a radial gas-phase oxygen abundance gradient based solely on auroral lines, and obtain the following least-square solution: 12+log(O/H)=8.57-0.41 R/R25, where the galactocentric distance is expressed in terms of the isophotal radius R25. The gradient corresponds to -0.077 dex/kpc, and agrees very well with the galactocentric trend in metallicity obtained for 29 B and A supergiants in the same galaxy. The intercept of the regression for the nebular data virtually coincides with the intercept obtained from the stellar data. This allows little room for depletion of nebular oxygen onto dust grains, although in this kind of comparison we are somewhat limited by systematic uncertainties, such as those related to the atomic parameters used to derive the chemical compositions. We discuss the implications of our result with regard to strong-line abundance indicators commonly used to estimate the chemical compositions of star-forming galaxies, such as R23. By applying a few popular calibrations of these indices based on grids of photoionization models on the NGC 300 HII region fluxes we find metallicities that are higher by 0.3 dex (a factor of two) or more relative to our nebular (Te-based) and stellar ones. We confirm a metallicity dependence of the `softness' parameter eta=(O+/O++)/(S+/S++), in the sense that softer stellar continua are found at high metallicity.

description: We study the work fluctuations of a particle, confined to a moving harmonic potential, under the influence of friction and external Poissonian shot noise. The asymmetry of the noise induces an effective nonlinearity in the potential, which in turn leads to singular features in the work distribution. On the basis of an analytic solution we find that the conventional fluctuation theorem is violated in this model, even though the distribution exhibits a large deviation form. Furthermore, we demonstrate that the interplay of the various time scales leads to critical behaviors, such as a negative fluctuation function and a divergence in the work distribution at the singularity. In a certain parameter regime large negative work fluctuations are more likely to occur than the corresponding positive ones, though the average work is always positive, in agreement with the second law.

description: A nanometer-sized superconducting quantum interference device (nanoSQUID) is fabricated on the apex of a sharp quartz tip and integrated into a scanning SQUID microscope. A simple self-aligned fabrication method results in nanoSQUIDs with diameters down to 100 nm with no lithographic processing. An aluminum nanoSQUID with an effective area of 0.034 $μ$m$^2$ displays flux sensitivity of 1.8$\cdot 10^{-6}$ $Φ_0/\mathrm{Hz}^{1/2} and operates in fields as high as 0.6 T. With projected spin sensitivity of 65 $μ_B/\mathrm{Hz}^{1/2}$ and high bandwidth, the SQUID on a tip is a highly promising probe for nanoscale magnetic imaging and spectroscopy.

Electron spin resonance spectra of some gaseous free radicals
Creators: name: Ferraro, William Charles
Publisher: name: University of British Columbia
Year: 2011

description: The products from a gaseous r.f. electric discharge in ammonia have been studied using electron spin resonance spectroscopy. A paramagnetic species from the discharge was detected and the results were consistent with it being the imine (NH) free radical. The E.S.R. Spectrum fitted the theoretical treatment and was similar to that observed for NH in a frozen matrix. No other radicals could be detected in the discharge except for the atomic species. The low pressure gas phase E.S.R. spectrum of (formula omitted) was also studied. The results showed that at low pressures the spectrum becomes exceedingly complex. A partial assignment of lines was made from the results of a simplified treatment of the theory. The work served a further purpose in developing experimental techniques for the study of unstable free radical species in the gas phase.
title: Vocalizations in a Population of Green-Tailed Towhees (Chlorura chlorura)

Publisher: name: Utah State University
Year: 1974

description: Studies of vocalizations in a montane population of Green-Tailed Towhees were conducted during the summer months of 1971 and 1972 in Cache County, Utah. The song and call repertoiries of 10 breeding pairs were recorded and analyzed on a sound spectograph.
Males averaged 8.7 different song and 18.2 different not types. Song variation on the population level is high (58 different songs) but the sharing of these songs among the males is low (22.4). Populational note structure is equally diverse but reveals a greater degree of sharing (75%).
Both males and females used three calls, the meow, tick, and poitt, whereas at least three more, the rattle, tst-tst-tst, and skee-skee-skee, are used only by the female.
Recoginition of the songs of conspecifies apparently is promoted by the distinctive introductory note, the duration of the song and the abruptness of changes within it.

description: In der vorliegenden Dissertation, die bereits 1996 in erster Auflage erschien und jetzt ergänzt und überarbeitet wurde, geht es hauptsächlich darum, den Aufbau der Lernersprache (interlanguage) in der speziellen, als ‚exolingual’ bezeichneten Konversationssituation aufgrund von linguistischen und Spracherwerbstheorien und unter Berücksichtigung von psychischen und sozialen Bedingungsfaktoren aus interdisziplinärer Perspektive empirisch zu dokumentieren. Exolingual heißt, dass die Gesprächspartner ein unterschiedliches Niveau in der Sprachkompetenz haben. Beteiligt sind meistens ein native speaker und eine lernende Person, im Gegensatz zu einer endolingualen Situation, in der beide Teilnehmenden ein vergleichbares Niveau haben. Konversation ist nicht synonym mit Kommunikation, denn es werden in der Gesprächsanalyse nur die verbalen Teile analysiert.

description: An alternative methodology to investigate indirect polyatomic processes with quasi-classical trajectories is proposed, which effectively avoids any binning or weighting procedure while provides rovibrational resolution. Initial classical states are started in terms of angle-action variables to closely match the quantum experimental conditions and later transformed into Cartesian coordinates, following an algorithm very recently published [J. Chem. Phys. 130, 114103 (2009)]. Trajectories are then propagated using the 'association' picture, i.e. an inverse dynamics simulation in the spirit of the exit-channel corrected phase space theory of Hamilton and Brumer [J. Chem. Phys. 82, 595 (1985)], which is shown to be particularly convenient. Finally, an approximate quasi-classical formula is provided which under general conditions can be used to add possible rotational structures into the vibrationally-resolved quasi-classical distributions. To introduce the method and illustrate its capabilities, correlated translational energy distributions from recent experiments in the photo-dissociation of ketene at 308 nm [J. Chem. Phys. 124, 014303 (2006)] are investigated. Quite generally, the overall theoretical algorithm reduces the total number of trajectories to integrate and allows for fully theoretical predictions of experiments on polyatomics.

title: The Unwed Father as Perceived by Himself
Creators: name: Ellis, Daryl E.
Publisher: name: Utah State University
Year: 1973

description: This study was designed to reveal the self perception of unwed fathers . Ten men participated in the project; nine of them were 25 years of age or younger. To measure self perception an instrument was constructed in the form of a questionnaire . Each um18d father was then interviewed to discover his perceptions, particularly as they relate to their common plight of unwed fatherhood.
The men perceived themselves as normal young Americans, and felt their conduct and intentions were in compliance, nth peer expectations. Some of the subjects responded to the interview, with descriptive and detailed accounts while others were either unconcerned or hesitant and replied in few words. None of the men (with two exceptions) were looking for new sexual partners. Only two of the unwed fathers had employed some form of conception control while having sexual relations with the mothers involved and these two did not do so regularly. The men were not contributing to the support of their child on a consistent basis, indicating their lack of involvement in a situation in which they share equal responsibility with the child's mother.
The emergence of a clearer picture of the unwed father, through the attempt to reveal his interests, problems, and concerns , may assist in the development of strategies and programs to prevent illegitimacy and to effectively aid those involved in it . Perhaps this study of the self perception of unwed fathers will be helpful in this regard.

description: Im Grenzland ist Besonderes Alltag: Probleme werden erfahrungsgemäß von mehreren Seiten betrachtet, gemeinsames Problemlösen und Austausch gehören zum Tagesgeschäft. So kann das Grenzland, von Zentren mitunter als peripher unterschätzt, gerade in der Kommunikation der Kulturen sozusagen von Haus aus mit Leistungen aufwarten, die in manchen Zentren so nicht möglich sind, weil dort die Theoriearbeit zwar weit entwickelt sein kann, die Begegnung mit der Empirie aber besonderer Anstrengung etwa in Form der Überwindung räumlicher Distanz bedarf. Das Saarland ist eine kulturell ebenso begünstigte Grenzregion wie das Dreiländereck um Basel insofern, als in ihm naturgemäß für Vereinfachungen und Verallgemeinerungen, für Dualismen und Dichotomien kaum Platz ist; es gilt die deutsche, die französische und (im Saarland) die luxemburgische Perspektive wahrzunehmen und diese fallweise in individuelles wie institutionelles Handeln zu überführen. Akademische Begleitung dieser Sondersituation hat ihren Niederschlag immer wieder in Buchreihen aus dieser Grenzregion gefunden. Seit einigen Jahren nun verlegt der Röhrig Universitätsverlag in St. Ingbert die Saarbrücker Studien zur Interkulturellen Kommunikation (mit Schwerpunkt Frankreich/Deutschland). Hans-Jürgen Lüsebrink, Romanist an der Universität des Saarlandes, gibt die Reihe in Verbindung mit Michel Grunewald und Bernd Krewer heraus. Mit dieser Rezension ist Band 7 der an Praxis wie an Theorie orientierten Reihe anzuzeigen: Konzepte der Interkulturellen Kommunikation - Theorieansätze und Praxisbezüge in interdisziplinärer Perspektive. Herausgegeben und mit einem die Beiträge charakterisierenden und synthetisierenden Vorwort versehen von Reihenherausgeber Lüsebrink, versammelt der 2004 erschienene Band Aufsätze aus Sicht von Anthropologie (König), Linguistik (Götze, Müller-Jacquier), Ethnologie (Moosmüller), Volkskunde (Roth), Psychologie (Thomas), Germanistik (Wierlacher), Kulturgeschichte (Dinges) und Betriebswirtschaft (Scholz).

description: Systematic Raman studies on several cuprates (YBa$_{\rm 2}$Cu$_{\rm 3}$O$_{\rm x}$, YBa$_{\rm 2}$Cu$_{\rm 4}$O$_{\rm 8}$ or Bi$_{\rm 2}$Sr$_{\rm 2}$CaCu$_{\rm 2}$O$_{\rm 8}$) have shown that at optimal doping the compounds are at the edge of lattice instability; once this level is exceeded, by means of doping or applying external hydrostatic pressure, the changes in the transition temperature are accompanied by spectral modifications. There are strong indications that the reduction in T$_{\rm c}$ is correlated with a separation into nanoscale phases, which involve the oxygen atoms of the CuO$_{\rm 2}$ planes. In this work, modifications with doping in the Raman spectra of the La$_{\rm 2-x}$Sr$_{\rm x}$CuO$_{\rm 4}$ compound are presented, which show that spin or charge ordering is coupled with lattice distortions in the whole doping region.

description: We investigate the calorimetric liquid-glass transition by performing simulations of a binary Lennard-Jones mixture in one through four dimensions. Starting at a high temperature, the systems are cooled to T=0 and heated back to the ergodic liquid state at constant rates. Glass transitions are observed in two, three and four dimensions as a hysteresis between the cooling and heating curves. This hysteresis appears in the energy and pressure diagrams, and the scanning-rate dependence of the area and height of the hysteresis can be described by power laws. The one dimensional system does not experience a glass transition but its specific heat curve resembles the shape of the $D\geq 2$ results in the supercooled liquid regime above the glass transition. As $D$ increases, the radial distribution functions reflect reduced geometric constraints. Nearest-neighbor distances become smaller with increasing $D$ due to interactions between nearest and next-nearest neighbors. Simulation data for the glasses are compared with crystal and melting data obtained with a Lennard-Jones system with only one type of particle and we find that with increasing $D$ crystallization becomes increasingly more difficult.

A proton magnetic resonance investigation of molecular motion in oleic acid and elaidic acid
Creators: name: Ware, Donald Robert
Publisher: name: University of British Columbia
Year: 2011

description: A study of the n.m.r. absorption of oleic acid has been carried out between 77°K. and 287°K. A sharp increase in line width and second moment is observed below 100°K. indicative of an increase in the intramolecular interactions. A narrow line, indicative of liquid-like motion, is observed at temperatures above 208°K. The second moment and line width decrease rapidly as the melting point is approached, dropping to liquid-like values at 287°K. The experimental data are compared with the theoretical data obtained from the known crystal structure. From this comparison, a crystal transition is proposed to take place below 100°K., and heteronuclear premelting is proposed to take place above 208°K. It is likely that end methyl group rotation takes place at all temperatures but there is no extensive torsional oscillation or vibration below 26o°K. and there is little apparent change in the cell dimensions between 260°K. and 100°K. Elaidic acid has been studied between 77°K. and 315°K. The line width and second moment increase slightly below 170GK. and a narrow component is observed above 225°K. The line width and second moment fall sharply only at the melting point, decreasing to a liquid-like line. As no crystal structure is available for elaidic acid, the experimental data are compared with experimental and theoretical data for oleic acid and stearic acid. Some form of molecular vibration or hindered rotation is proposed to account for the transition at 170°K., and heteronuclear premelting is proposed to take place above 225°K. The difference in the behaviour of oleic acid and elaidic acid near the melting point is explained in terms of the molecular shape.

description: Grammatik, wie sie im Fremdsprachenunterricht optimal vermittelt werden kann/soll, gehört zu den kontrovers diskutierten Fragen der Fremdsprachendidaktik. Ein Rückblick auf die Geschichte des modernen Fremdsprachenunterrichts reicht, um sich davon zu überzeugen: Je nach dem theoretischen Ausgangspunkt wurde Grammatik verabsolutiert, tabuisiert, ja sogar völlig abgelehnt. Allerdings sind seit den frühen 90er Jahren des 20. Jahrhunderts Forschungsansätze zu verzeichnen, die trotz ihrer Vielfalt die Rolle der Grammatik beim Fremdsprachenerwerb zu schätzen wissen und dementsprechend einer bewussten Herangehensweise an grammatische Phänomene im Unterricht das Wort reden. In diesen Zusammenhang gehört auch der vorliegende Band, der dramapädagogische Ansätze für die Vermittlung der Grammatik im DaF-Unterricht diskutiert. Dabei gilt das primäre Interesse der Autorin „der Aspektvielfalt von Dramagrammatik, deren Ermittlung den Boden für nachfolgende wissenschaftliche Arbeiten, die sich mit der Analyse einzelner Aspekte auseinandersetzen, bereiten soll“ (22)
title: When the Children are Gone: Changes in Mental Health and Marital Relations During the Transition to Postparenthood
Creators: name: Cannon, Kenneth Holland
Publisher: name: Utah State University
Year: 1984

description: A longitudinal research design was used to determine if parents' personal well-being or marital relations changed after the launching of the youngest child and what variales might affect these potential changes.
Eighty-nine parents whose youngest child was a senior at Logan High School or Sky View High School responded to mail-out questionnaires, assessing parents general well-being, marital relations, marital companionship, personal stress, quality of parenting experiences and degree of parent-child conflict. Approximately one year later, a second questionnaire was sent and twenty-three of the parents who responded had launched their youngest child.
One of the most striking aspects of the results of this study was the general lack of statistically significant findings. For most individuals, launching of the youngest child had little positive or negative affect on parents personal well-being or marital relations.
Significant relationships were found for parents who had low quality parenting experiences or whose relationships with their youngest child tended to be conflictful. These findings suggest that low quality parenting experiences or high amounts of parent-child conflict negatively impact personal well-being and marital relations and that the launching of the youngest child lessens the negative impact of these two variables. The exception to this finding was that low quality parenting experiences was significantly r elated to parents' marital satisfaction regardless of whether or not the youngest child left home.

description: Das Buch von Wolfgang Butzkamm ist aus mehreren Gründen bemerkenswert. Einerseits ist es ein Aufruf, die Schule von Grund auf zu erneuern, andererseits ist es ein praktischer Ratgeber für Fremdsprachenlehrer, allerdings nur für solche, die bereit sind neue Wege zu gehen, denn der Autor stellt fast das ganze heutige Methodenwissen in Frage oder vielmehr vom Kopf auf die Füße. Auf jeder Seite finden sich neue Ideen, und auf jeder Seite wird Kritik an den heute herrschenden methodischen Moden geübt. Das Buch ist voller Anregungen, die den Leser überraschen, wundern, manchmal sogar schockieren, aber letzten Endes doch überzeugen, denn alles wird mit konkreten Beispielen belegt und in der Praxis getestet. Es ist ein Buch für alle Lehrer, die von der heutigen Unterrichtpraxis enttäuscht sind, die nicht verstehen, warum die anfangs enorm große Motivation zum Fremdsprachenlernen bei den Schülern so schnell schwindet. Der Leser findet in diesem Band eine Diagnose der jetzigen Situation und konkrete, sehr detailliert beschriebene Vorschläge, wie man die aktuellen Probleme angehen kann.

description: The effect of tutorial instruction was studied as it influences number concept development in preschool children. The research was conducted in the Logan and Providence areas of Cache County, Utah, with 24 non-preschool four-year-old children. Twelve of the children were given tutorial experience through the use of children's flannel board stories written by the author. The stories were developed to t each the number concepts of not first or last, second, third, pair, and Medium sized.
It was found that the 12 children who received tutorial experiences significantly increased in score on the Boehm Test of Basic Concepts from the pre-test to the first post-test, and further, that there was a slight but insignificant loss of knowledge after a six-week waiting period on the number concepts taught. The control group, which received no tutorial experience, made no significant gain in score on any of the tests.
The findings also indicated that there was no significant difference between boys and girls on their ability to learn and retain number concepts. The control group boys made a slight gain in score from the pre-test to the second post-test that was unrelated to any tutorial experience.

description: Pancreatic adenocarcinoma is a highly aggressive malignancy with disease-related mortality almost equaling its incidence. The notorious resistance of pancreatic cancer not only to conventional cytotoxic therapies but also to almost all targeted agents developed to date continues to puzzle the oncological community and represents one of the biggest hurdles to reduce the death toll from this ominous disease. Currently, we have been focusing on developing nanosecond electric pulse or nano-pulse (NP) technology for cancer therapy. However, due to the demand for high electric fields, all currently available designs of NP delivery systems are only able to treat tumors with small sizes (4-7 mm). To solve this problem, we propose a combination of NP with non-thermal plasma or cold plasma (CP) to treat large tumors.

Our hypothesis is that the synergistic effect between NP and CP-produced reactive plasma species can be utilized to treat large tumors with sizes relevant to human cancer. First, the dose-dependent cytotoxicity of NP or CP to Pan02 pancreatic cancer cells was examined by cells treated with different doses of NP or CP. Second, we selected one specific dose of NP for further combination evaluation. The combination treatment was carried out either by treating cells with NP first then CP, or CP first then NP. The synergistic effect was assessed with cell viability and impedance measurement. Our results showed that NP at a very low dose can sensitize cancer cells that will then be killed by CP.

Our future goals are to develop a prototype engineering system for both NP and CP delivery to tumor tissue, to evaluate the synergistic effect of NP and CP in vitro and in vivo, and to explore the potential molecular mechanisms of the synergistic effect of NP and CP.
title: Planned Parenthood and Fertility, Illegitimacy, and Abortion Rates in the State of Utah
Creators: name: Godfrey, Wayne W.
Publisher: name: Utah State University
Year: 1984

description: The purpose of this study was not to judge the rightness or wrongness of Planned Parenthood. It is an empirical question to ask what influence, if any, Planned Parenthood has had on reproductive behavior in the State of Utah. This was accomplished by gathering data from each county in the State of Utah from 1970 to 1979. The data gathered were for the five dependent variables of General Fertility, General Abortion, General Illegitimacy, Teen Fertility and Teen Illegitimacy. A mean rate for each county and variable was computed. Each county was also weighed per population so as to give counties with large populations more weight than counties with small populations. A comparison of the rates in counties with Planned Parenthood and counties without Planned Parenthood was then made. It was noted that counties with Planned Parenthood had higher rates for each variable except General Fertility which was lower than counties without Planned Parenthood. But the differences were not of a significant level. In most cases the differences already existed before Planned Parenthood was established.

description: In recent works, we have proposed a stochastic cellular automaton model of traffic flow connecting two exactly solvable stochastic processes, i.e., the Asymmetric Simple Exclusion Process and the Zero Range Process, with an additional parameter. It is also regarded as an extended version of the Optimal Velocity model, and moreover it shows particularly notable properties. In this paper, we report that when taking Optimal Velocity function to be a step function, all of the flux-density graph (i.e. the fundamental diagram) can be estimated. We first find that the fundamental diagram consists of two line segments resembling an {\it inversed-$λ$} form, and next identify their end-points from a microscopic behaviour of vehicles. It is otable that by using a microscopic parameter which indicates a driver's sensitivity to the traffic situation, we give an explicit formula for the critical point at which a traffic jam phase arises. We also compare these analytical results with those of the Optimal Velocity model, and point out the crucial differences between them.

title: Family Conditions and Practices Related to Waste Paper Output
Creators: name: Call, Dena Lee Child
Publisher: name: Utah State University
Year: 1973

description: Paper waste discarded by families of five persons in Logan City was studied for two seven-day periods. The sample consisted of 42 families comprised of a father who was employed full-time, a mother, and three children living at home. A questionnaire was administered to each family for the purpose of describing the sample, and to determine some of their family conditions and practices.
Sample families were given plastic bags for storing of waste paper, which was collected at the end of each seven-day period. The weight of all paper discards was tabulated for each family. Seven of these families were put in a category of high paper output and seven families were put in a category of low paper output. Averages were tabulated for the total sample, high paper output category, and low paper output category.
The highest and lowest total paper weights recorded for the 14 days were 62 pounds 5 ounces and 7 pounds 15 ounces respectively.
The average weight for all families was 18 pounds 12 ounces. The average high paper output category was 37 pounds 11 ounces. The average low paper output category was 9 pounds 3 ounces. Through comparing these weights with information found on the questionnaires, the following may be said to have an effect on the amount of paper families discard: method of disposing of newspapers, income, and perhaps occupation of the father.

description: Weltweite gesellschaftspolitische Entwicklungen und Wandelungen sind zweifelsohne Herausforderungen, die ein neues Konzept von Aus- und Weiterbildung in allen Bereichen des menschlichen Lebens erfordern. Auch der Fremdsprachenunterricht kann diesen Entwicklungen nicht gegen halten und ist somit im Begriff, sich bezüglich der Zielsetzungen, Inhalte und Verfahren zu verändern. Wesentliche Merkmale dieser Veränderungen sind unter anderem der Frühbeginn des Fremdsprachenlernens, die Entwicklung von Mehrsprachigkeit, das Lernen mit neuen Medien, Selbständigkeit der Lerner und die Vorbereitung zu einer lebensbegleitenden Fortsetzung des Lernens von Sprachen. Hier ist besonders die Relevanz des lebenslangen Lernens hervorzuheben, da die Bildungspolitik der heutigen Weltordnung es sich konsequenterweise zum Ziel gesetzt hat, das lebenslange Lernen zu einer Wirklichkeit für alle zu machen. So plädiert auch der Europarat für die Schaffung eines europäischen Raums des lebenslangen Lernens², um Europa zur wettbewerbsfähigsten und dynamischsten Wissensgesellschaft der Welt zu machen. Folglich ist es als eine der Basisaufgaben des Bildungswesens anzusehen, das Lernen im Allgemeinen und das Fremdsprachenlernen im Besonderen als einen lebenslangen Prozess der Aus- und Weiterbildung anzusehen, der kontinuierlich durchdacht, revidiert und von neuem umgestaltet werden muss.

description: We find evidence for accelerated evolution in compact group galaxies from the distribution in mid-infrared colorspace of 42 galaxies from 12 Hickson Compact Groups (HCGs) compared to the the distributions of several other samples including the LVL+SINGS galaxies, interacting galaxies, and galaxies from the Coma Cluster. We find that the HCG galaxies are not uniformly distributed in colorspace, as well as quantitative evidence for a gap. Galaxies in the infall region of the Coma cluster also exhibit a non-uniform distribution and a less well defined gap, which may reflect a similarity with the compact group environment. Neither the Coma Center or interacting samples show evidence of a gap, leading us to speculate that the gap is unique to the environment of high galaxy density where gas has not been fully processed or stripped.

title: A Look at Some Grandfather Intergenerational Relationships As Perceived by Their Adult Children
Creators: name: Stout, Leonard E.
Publisher: name: Utah State University
Year: 1984

description: The purpose of this study was to investigate the quality of grandfather's relationships with his adult child and their oldest child. A questionnaire was used to obtain demographic data, determine some personality and interaction patterns that can be observed as the male adult develops in the parent and grandparent roles, and examine how specific variables affect grandfather relationships and behavior. Data were gathered from 165 Utah State University students and their spouses , of which over 75% belong to the Church of Jesus Christ of Latter-day Saints.
The results support good intergenerational relationships. Proximity of grandfather and extended family members was on the average 23 miles. The grandfather and adult child visited each other on the average of five times monthly. Grandfathers were seen as helpful, affectionate, and willing to sacrifice for the adult child if in need.
Insufficient data were gathered to support a conclusion that the quality of grandfather ' s relationship with either the adult child or the grandchild would be significantly related to grandfather age or the family member's sex .
Some trends suggest that females are more accepting of help from the grandfather . Also older grandfathers tended to be perceived to have a more positive relationship than their younger counterparts.
Perceptions of grandfathers' changing behavior over time indicated most grandfathers ' behaviors remain stable . When change did take place, it was significantly more likely to be in the direction of increased warmth and nurturing behaviors.

description: “Der frühzeitige Fremdsprachenerwerb, die Förderung der Beherrschung mehrerer Sprachen und die Schaffung einer Kultur der Mehrsprachigkeit mit Hilfe eines breiter gestreuten schulischen Sprachangebots, sind vorrangige Zielsetzungen europäischer Initiat iven…”¹ Der Frühbeginn in einer Fremdsprache ist heute nunmehr eines der zentralen Themen des Fremdsprachenlernens² und als solches auch wesentlicher Bestandteil der allgemeinen Bildungspolitik. Insbesondere nach dem Beschluss der Europäischen Kommission 1993 zur obligatorischen Einführung der zweiten Fremdsprache, hat eine konstruktive, aber auch kritische Phase in der europäischen Fremdsprachenausbildung und den impliziten Spracherziehungskonzepten begonnen. In Ländern, in denen das Fremdsprachenlernen eher einen sekundären Stellenwert im gesamten Ausbildungssystem hatte, setzte eine komplette Neuorientierung ein, mit weitreichenden Änderungen auch in der Bildungspol itik. Länder wie z.B. Holland, in denen Fremdsprachen schon immer eine wichtige Rolle im Schul- und Bildungssystem spielten, konnten ihre bewährten Modelle problemlos in die Diskussion einbinden und somit um einen Schritt weiter über die Umsetzbarkeit der Idee von der europäischen Sprachenvielfalt nachdenken. Mittlerweile werden in fast allen europäischen Ländern auch oder insbesondere im Hinblick auf die gesamteuropäischen Bildungsprogramme und -initiativen (ComeniusProgramme³) neue Konzepte in die Praxis umgesetzt, denn Sprachenvielfalt ist nur zu leisten, wenn mehrere Fremdsprachen zum festen Bestandteil der Bildungs- und Erziehungsarbeit werden. So paradox es auch klingen mag, die europäische Neuorientierung in der Fremdsprachenpolitik fußt auf dem Interesse, die europäische Sprachenvielfalt gegenüber der Dominanz der Englischen zu erhalten. Ein erster Schritt in diese Richtung stellt die Erweiterung des Fremdsprachenangebotes bereits in der Grundschule dar.⁴ Neben Englisch, Deutsch und Französisch gilt es kleinere und in erster Linie Sprachen der Nachba rländer zu fördern. Sukzessive zum Beschluss der europäischen Kommission zur obligatorischen Einführung einer zweiten Fremdsprache stellte sich die Frage nach der Qualitätsentwicklung und Qualitätssicherung. Damit einher geht es um die zunächst rein organisatorische Frage nach dem Beginn der ersten Fremdsprache und dem Zeitpunkt für den Beginn mit der zweiten Fremdsprache in z.T. unterschiedlichen Schulsystemen. Weiterhin stellte sich die Frage nach der erreichbaren Sprach- und Lernkompetenz, die je nach Profil und Anforderungen unterschiedlich aussehen kann und sollte. Eine umfassende Antwort dazu liefert der Europäische Referenzrahmen, in dem von A1 bis C2 unterschiedliche Sprachstandsstufen genannt und beschrieben sind. Alle diese Bemühungen und Maßnahmen zeigen deutlich, dass die fremdsprachliche Ausbildung Teil eines umfassenden Standardisierungsprozesses auf Bildungsebene ist.⁵

description: The valley splitting in Si two-dimensional electron systems is studied using Si/SiGe single quantum wells (QWs) with different well widths. The energy gaps for 4 and 5.3 nm QWs, obtained from the temperature dependence of the longitudinal resistivity at the Landau level filling factor $ν=1$, are much larger than those for 10 and 20 nm QWs. This is consistent with the well-width dependence of the bare valley splitting estimated from the comparison with the Zeeman splitting in the Shubnikov-de Haas oscillations.

description: A superconducting wiggler has been designed and built at Laboratori Nazionali INFN in Frascati, Italy, in collaboration with Ansaldo Componenti-Genova, to be used as an insertion device in the Adone storage ring. It will be used as a light source on the 1.5 GeV, 100mA electron beam of the accelerator, to produce about 10^12 photons/s/mrad in 0.1% band width, in the short X-ray wavelength range. In order to minimize the electron beam orbit distortion and to obtain the best phase space distribution of the generated synchrotron radiation (a single bright spot), a superconducting dipole, producing a sharp vertical field peak (6T, 12cm FWHM), between two normal conducting side dipoles (0.8T), to compensate the field integral, has been manifactured. The s.c. dipole is made up of 2NbTi coils, separated by a central plate and kept together by two 356kg total weight iron yokes. The magnet gap is 6 cm and the design current is 360 A. The system is contained in a warm bore cryostat and cooled by boiling helium at 4.6 K. The static cryostat helium consumption is of 4 l/h and, when the cryomagnet is energized, it is cooled by a 1430 S Koch liquefier/refrigerator on line with it through transfer lines. The stored energy is 184 kJ. This paper describes the latest status of the facility and the verification tests. PACS 85.25 - Superconducting devices; superconducting magnets.

description: In this paper, we study an exact solution of the asymmetric simple exclusion process on a periodic lattice of finite sites with two typical updates, i.e., random and parallel. Then, we find that the explicit formulas for the partition function and the average velocity are expressed by the Gauss hypergeometric function. In order to obtain these results, we effectively exploit the recursion formula for the partition function for the zero-range process. The zero-range process corresponds to the asymmetric simple exclusion process if one chooses the relevant hop rates of particles, and the recursion gives the partition function, in principle, for any finite system size. Moreover, we reveal the asymptotic behaviour of the average velocity in the thermodynamic limit, expanding the formula as a series in system size.
