Personal clothing in Wolfram’s Parzival and Willehalm : Symbolism and significance
Creators: name: Barran, Paula A.
Publisher: name: University of British Columbia
Year: 2010

description: This study is a discussion of the use of clothing symbolism by Wolfram von Eschenbach in Parzival and in Willehalm, investigating whether he did in fact use clothing symbols, how he made use of them, and suggesting some explanation for why he used them. The reasonableness of the hypothesis that clothing symbols were used is established by the existence of a strong symbolic tradition in the times in which Wolfram was writing, an era in which everything participated in the fundamental underlying unity of all creation and therefore had the potential for acting as symbols of those aspects to which a relationship was established. The hypothesis is further supported by the existence of confessed clothing symbolism in the garments used in the services of the Church during Wolfram's lifetime, and made likely by the use of admitted clothing symbols in the narrative poetry of Wolfram's contemporaries, notably Hartmann von Aue, Gottfried von Strassburg, and the author of the Nibelungenlied. Elements of medieval clothing which contribute to the symbolic potential of the various garments are examined. These include color and style as well as legal restrictions covering the use of certain clothing styles by certain classes of society. The following groups of clothing and clothing-related articles are considered separately: armor, clothing on formal occasions, daily clothing, gemstones, gifts of clothing and aid offered in the act of robing and disrobing. The same distinctions are followed in the discussion of personal clothing in Willehalm, but the discussion is confined to a single chapter. Individual considerations which are important in establishing a firm support for the arguments are elements of contemporary culture which establish symbolic significance for certain articles, among them lapidaries, bestiaries, and the customs of the Church. A very important aspect of the argument is the establishment of an interpretation that is coherent in terms of the parameters of the narrative as a whole. The general conclusions reached are that the use of clothing symbolism is supported by personal admission of the author, the existence of a strong tradition, and by poetic use within the narrative, notably by the creation of incongruity of situation which indicates an extended meaning. Clothing symbols are valuable tools for the poet's characterization as well as for scene linkage and are used furthermore to suggest an inner reality which is not necessarily supported by the external evidence offered.
title: LENA Measurements of Language Facilitation Strategies Utilized by Parents during Storybook Reading

description: Approximately 12,000, or 4-6 per 1,000 babies per year in the United States are born with some degree of hearing loss (NCHAM, 2014). Children with any degree of hearing loss are at risk for having difficulty with academics, language and communication. However, with early detection, and use of hearing technology (e.g. hearing aids and cochlear implants), and specialized early intervention, many children who are Deaf and Hard of Hearing (DHH) can develop language and academic proficiency at or near their same aged peers (Moeller, 2000). The development of age-appropriate literacy skills in children who are DHH is essential in establishing the foundations of academic success. Because many aspects of literacy acquisition are based on the phonemic elements of written text, appropriate supports for children with hearing loss to promote early literacy skill development will optimize growth and progress. Easterbrooks (2010) reported five main components that help children who are DHH develop emergent literacy, including, 1) parent involvement, 2) a language rich environment, 3)storybook reading, 4) a supportive classroom environment, 5) and early intervention services. Because literacy is vital to a child’s development, this proposal will describe 1) the impact of hearing loss and benefits of hearing technology 2) the importance of early intervention with children who are DHH by involving parents through storybook reading, and 3) strategies that have been developed to help facilitate language in DHH children. These include developing the skills to use acoustic highlighting, asking questions that facilitate critical thinking and promote text comprehension, and utilizing appropriate wait time after asking targeted questions so that the child has time to think and offer a response.

description: RESUMO

Diante de um cenário de perpetuação de desigualdades étnicas e raciais, esta pesquisa tem por objetivo compreender as principais conquistas e desafios para a implementação da Educação para as relações étnico-raciais nas escolas públicas do Estado de Pernambuco. Amparamo-nos metodologicamente na pesquisa bibliográfica e documental (Gil, 2002), por meio da qual realizamos estudos teóricos em livros, artigos e documentos legais que versam sobre a temática em questão. Os resultados indicam que, embora exista legislação específica e políticas públicas voltadas para a educação étnico-racial, ainda temos um cenário de falta de formação continuada para professores e gestores, a ausência de materiais didáticos adequados, o insuficiente suporte institucional para monitorar as ações implementadas. Conclui-se que para que a educação para as relações étnico-raciais seja efetivamente incorporada nas escolas públicas de Pernambuco, é necessário um esforço conjunto entre gestores, professores e políticas públicas, com a oferta de formações contínuas e materiais didáticos de qualidade.

description: The class of scalar-tensor theories with the scalar field coupling to the Gauss-Bonnet invariant has drawn great interest since solutions of spontaneous scalarization were found for black holes in these theories. We contribute to the existing literature a detailed study of the spontaneously scalarized neutron stars (NSs) in a typical theory where the coupling function of the scalar field takes the quadratic form and the scalar field is massive. The investigation here includes the spherical solutions of the NSs as well as their perturbative properties, namely the tidal deformability and the moment of inertia, treated in a unified and extendable way under the framework of spherical decomposition. We find that while the mass, the radius, and the moment of inertia of the spontaneously scalarized NSs show very moderate deviations from those of the NSs in general relativity (GR), the tidal deformability exhibits significant differences between the solutions in GR and the solutions of spontaneous scalarization for certain values of the parameters in the scalar-Gauss-Bonnet theory. As a result, the celebrated universal relation between the moment of inertia and the tidal deformability of neutron stars breaks down. With the mass and the tidal deformability of NSs attainable in the gravitational waves from binary NS mergers, the radius measurable using the X-ray satellites, and the moment of inertia accessible via the high-precision pulsar timing techniques, future multi-messenger observations can be contrasted with the theoretical results and provide us necessary information for building up theories beyond GR.

description: We investigate the spectral and temporal properties of ultra-luminous X-ray source (ULX) NGC~55~ULX1 using {\it Swift}, {\it XMM-Newton} and {\it NuSTAR} observations conducted during 2013--2021. In these observations, the source flux varies by a factor of $\sim 5-6$, and we identify the source mainly in the $soft~ultraluminous$ (SUL) state of ULXs. We fit the X-ray spectra with a two thermal component model consisting of a blackbody (for the soft component) and a disc (for the hard component), and the soft component dominates in these observations. The soft component in the SUL state shows properties similar to that of ultraluminous supersoft sources, for example, an anti-correlation between the characteristic radius and temperature of the blackbody component. In addition, we observe a positive correlation between the blackbody and inner disc temperatures when the X-ray spectra are fitted with the two-thermal component model. The source exhibits marginal evidence of X-ray flux dips in the {\it Swift} and {\it XMM-Newton} observations at different intensity levels. We explain the observed spectral and temporal properties of the source by invoking the supercritical radiatively driven outflow mechanism.

description: We report on scanning tunneling microscopy and spectroscopy of grain boundaries in highly oriented pyrolytic graphite. Grain boundaries showed a periodic structure and an enhanced charge density compared to the bare graphite surface. Two possible periodic structures have been observed along grain boundaries. A geometrical model producing periodically distributed point defects on the basal plane of graphite has been proposed to explain the structure of grain boundaries. Scanning tunneling spectroscopy on grain boundaries revealed two strong localized states at -0.3 V and 0.4 V.

title: Development of AWWA Recommendations for CCL4 Prioritization and Process
Creators: name: Bench, Ryan Worth
Publisher: name: Utah State University
Year: 2015

description: Every 5 years the USEPA is responsible to publish a list of unregulated contaminants that are known or expected to occur in public water systems in the United States that may pose a risk on public health. This list is known as a contaminant candidate list (CCL). This year it is expected that the USEPA is to publish the 4th such list of the CCL or CCL4. Candidacy to be on the CCL4 is based on a compound’s occurrence in the environment, public health toxicity and recommendation from expert opinion. Methods to qualitatively determine occurrence and toxicity for compounds were developed in this research and based off USEPA methods. This process involved looking at a large range of chemicals/compounds found in the environment from varying groups such as: disinfection bi‐products, pharmaceuticals, pesticides, inorganics, volatile organic compounds, industrial and cyanotoxins. These compounds may have been included on previous CCL lists or are contaminants of concern currently found in the drinking water industry. Data approaches such as the creation of a master sheet, space diagrams and numerical algorithms ranked compounds based on occurrence and toxicity. These data approaches, along with others, were then provided to an expert panel (TAW) that considered all of these tools, in addition to others, to develop expert opinions about the top candidates for the CCL4. Results from this approach categorized the compounds and binned them into 4 groups. Of the 122 studied compounds, recommendations for the USEPA are as followed: Group 1. Top priority for inclusion in CCL4 (7 compounds and super‐group DBPs). Group 2. Recommend inclusion on CCL4 but insufficient data currently for regulatory determination (10 compounds). Group 3. Recommend inclusion on CCL4 based on sufficient data for negative regulatory determinations (33 compounds). Group 4. Recommend not to include in CCL4 (56 compounds).

description: This was a retrospective study including ninety samples of dogs with a histological diagnosis of intermediate grade cutaneous mast cell tumour (MCT). The objectives of the study were to validate Minichromosome Maintenance Protein 7 (MCM7) as a prognostic marker in MCTs and to compare the ability of mitotic index (MI), Ki67 and MCM7 to predict outcome. The median survival for the entire population was not reached at 2099 days. The mean survival time was 1708 days. Seventy-two cases were censored after a median follow up of 1136 days and eighteen dogs died for causes related to the MCT after a median of 116 days. For each sample MI, Ki67 and MCM7 were determined. The Receiver Operating Characteristic (ROC) curve was obtained for each prognostic marker to evaluate the performance of the test, expressed as area under the curve, and whether the published threshold value was adequate. Kaplan-Meier and corresponding logrank test for MI, Ki67 and MCM7 as binary variables was highly significant (P<0.0001). Multivariable regression analysis of MI, Ki67 and MCM7 corrected for age and surgical margins indicated that the higher risk of dying of MCT was associated with MCM7 > 0.18 (Hazard Ration [HR] 14.7; P<0.001) followed by MI > 5 (HR 13.9; P<0.001) and Ki67 > 0.018 (HR 8.9; P<0.001). Concluding, the present study confirmed that MCM7 is an excellent prognostic marker in cutaneous MCTs being able to divide Patnaik intermediate grade tumours in two categories with different prognosis. Ki67 was equally good confirming its value as a prognostic marker in intermediate grade MCTs. The mitotic index was extremely specific, but lacked of sensitivity. Interestingly, mitotic index, Ki67 and MCM7 were independent from each other suggesting that their combination would improve their individual prognostic value.
La Historia de la Frontera y el Romancero Fronterizo
Creators: name: Reventlow, Dolores
Publisher: name: University of British Columbia

description: The object of this thesis is to examine the circumstances in which the 'rorriancero fronterizo' made its appearance and to attempt to determine when and where these romances were composed, and their relation to history. In order to understand the peculiar climate in which these 'romances' were probably written, an outline is given of the history of Castilla in the XV century and of the history of the kingdom of Granada during the same period. From this study emerges a picture of life in the frontier, which sets the scene for the 'romances fronterizos'. The word 'romance' itself alludes, at first, to the vernacular, and later to narrative verse written in octosyllables. The 'romances antiguos' in general are fragments of older epics. The peculiarity about the 'romances fronterizos' is that they do not refer back to epic poems. According to some critics they sprang from the immediate impact of the episodes they narrate. This was R. Menendez Pidal's position. Deyermond combines composition by a single poet with collaborative authorship. A. Rodriguez-Monino appears to accept Nucio's statement that the romances he printed were obtained by word of mouth. Others situate the composition at the royal court or at a later date. In order to arrive at a conclusion regarding these points, we have studied 19 'romances'. While it has been possible to situate each of them in a given historical situation, they do not all adhere strictly to historic reality. Some, starting from a real happening, dramatize the moment with romanesque details. Others, of which the outstanding exponent is ''Abenamar, Abenamar...", starting from a true historical moment (here the incursion of Juan II in Granada in 1431) present an entirely fictitious episode. And yet others present history as it happened. Comparing the 'romances' with the presentation of the historical moment by the Chronicles, we try to determine the relationship between them. We find that the 'romances fronterizos' that we have analyzed form a distinctive group with characteristics peculiar to them but not necessarily found all in each of them. Their common denominator is their theme: they are all narrations of border episodes that focus on a moment of particular dramatic impact. The most important link that unites the 'romances fronterizos' and separates them from the other 'romances' is the spirit of the frontier, a projection of the history of the frontier that finds expression in the attitude of the poet towards life in that frontier which he shares with the Muslims. This co-existence has created an understanding of the problems of the enemy and an attitude towards him that is reflected in the poems. This group of 'romances' were, we believe, written in the small courts of the nobles along the frontier by professional poets. They were the product of the historical moment and of literary tradition and are a perfect expression of a unique atmosphere in a given historical setting.
A dynamic model of time-dependent complex networks

description: The characterization of the "most connected" nodes in static or slowly evolving complex networks has helped in understanding and predicting the behavior of social, biological, and technological networked systems, including their robustness against failures, vulnerability to deliberate attacks, and diffusion properties. However, recent empirical research of large dynamic networks (characterized by connections that are irregular and evolve rapidly) has demonstrated that there is little continuity in degree centrality of nodes over time, even when their degree distributions follow a power law. This unexpected dynamic centrality suggests that the connections in these systems are not driven by preferential attachment or other known mechanisms. We present a novel approach to explain real-world dynamic networks and qualitatively reproduce these dynamic centrality phenomena. This approach is based on a dynamic preferential attachment mechanism, which exhibits a sharp transition from a base pure random walk scheme.

description: We examine in some detail the influence of the systematics in different data sets including type Ia supernova sample, baryon acoustic oscillation data and the cosmic microwave background information on the fitting results of the Chevallier-Polarski-Linder parametrization. We find that the systematics in the data sets does influence the fitting results and leads to different evolutional behavior of dark energy. To check the versatility of Chevallier-Polarski-Linder parametrization, we also perform the analysis on the Wetterich parametrization of dark energy. The results show that both the parametrization of dark energy and the systematics in data sets influence the evolutional behavior of dark energy.

description: We revisit the high-energy spectral cutoff originating from the electron-positron pair creation in the prompt phase of gamma-ray bursts (GRBs) with numerical and analytical calculations. We show that the conventional exponential and/or broken power law cutoff should be drastically modified to a shallower broken power-law in practical observations that integrate emissions from different internal shocks. Since the steepening is tiny for observations, this "smearing" effect can generally reduce the previous estimates of the Lorentz factor of the GRB outflows. We apply our formulation to GRB 080916C, recently detected by the Large Area Telescope detector on the Fermi satellite, and find that the minimum Lorentz factor can be ~600 (or even smaller values), which is below but consistent with the previous result of ~900. Observing the steepening energy (so-called "pair-break energy") is crucial to diagnose the Lorentz factor and/or the emission site in the future observations, especially current and future Cherenkov telescopes such as MAGIC, VERITAS, and CTA.

description: The work is devoted to the sliding friction of rubber on a hard surface, for example, a car tire on asphalt, a shoe sole on a sidewalk, granite or marble steps, etc. In this case, the main attention is paid to the influence of the tread on rubber or other pliable base on the magnitude and nature of sliding or static friction. Until now, the generally accepted model of dry sliding friction is the model of contact interaction of roughness of contacting surfaces of bodies, in which the friction forces are determined by the energy costs for the deformation of irregularities. If one of the bodies is elastically deformable, then the nature of such interaction becomes somewhat different. And in the presence of a tread, the nature of the occurrence of additional friction forces becomes fundamentally different.
Flow-equation approach to quantum systems driven by an amplitude-modulated time-periodic force

description: We apply the method of flow equations to describe quantum systems subject to a time-periodic drive with a time-dependent envelope. The driven Hamiltonian is expressed in terms of its constituent Fourier harmonics with amplitudes that may vary as a function of time. The time evolution of the system is described in terms of the phase-independent effective Hamiltonian and the complementary micromotion operator that are generated by deriving and solving the flow equations. These equations implement the evolution with respect to an auxiliary flow variable and facilitate a gradual transformation of the quasienergy matrix (the Kamiltonian) into a block diagonal form in the extended space. We construct a flow generator that prevents the appearance of additional Fourier harmonics during the flow, thus enabling implementation of the flow in a computer algebra system. Automated generation of otherwise cumbersome high-frequency expansions (for both the effective Hamiltonian and the micromotion) to an arbitrary order thus becomes straightforward for driven Hamiltonians expressible in terms of a finite algebra of Hermitian operators. We give several specific examples and discuss the possibility to extend the treatment to cover rapid modulation of the envelope.

description: In a collisionless plasma, the energy distribution function of plasma particles can be strongly affected by turbulence. In particular, it can develop a non-thermal power-law tail at high energies. We argue that turbulence with initially relativistically strong magnetic perturbations (magnetization parameter $σ\gg 1$) quickly evolves into a state with ultra-relativistic plasma temperature but mildly relativistic turbulent fluctuations. We present a phenomenological and numerical study suggesting that in this case, the exponent $α$ in the power-law particle energy distribution function, $f(γ)dγ\propto γ^{-α}dγ$, depends on magnetic compressibility of turbulence. Our analytic prediction for the scaling exponent $α$ is in good agreement with the numerical results.

Exact expressions for hysteresis loops are obtained in the mean field approximation. These show rather unusual features. We also perform simulations of the two models on a simple cubic lattice and compare them with the predictions of the mean field theory.

description: We study the Hilbert expansion for small Knudsen number $\varepsilon$ for the Vlasov-Boltzmann-Poisson system for an electron gas. The zeroth order term takes the form of local Maxwellian: $ F_{0}(t,x,v)=\frac{ρ_{0}(t,x)}{(2πθ_{0}(t,x))^{3/2}} e^{-|v-u_{0}(t,x)|^{2}/2θ_{0}(t,x)},\text{\ }θ_{0}(t,x)=Kρ_{0}^{2/3}(t,x).$ Our main result states that if the Hilbert expansion is valid at $t=0$ for well-prepared small initial data with irrotational velocity $u_0$, then it is valid for $0\leq t\leq \varepsilon ^{-{1/2}\frac{2k-3}{2k-2}},$ where $ρ_{0}(t,x)$ and $ u_{0}(t,x)$ satisfy the Euler-Poisson system for monatomic gas $γ=5/3$.

description: This qualitative research reports on the experience of eight single person faculty seminary teachers as they participated in four collaborative structured discussions with a colleague, while using distance technology. The structure of each discussion consisted of discussion of a selected talk or article, the giving and receiving of feedback on a lesson plan, and the discussion of other ideas, concerns, problems, and questions. Data was also gathered in an exit interview. Constant-comparative analysis was used to discover patterns and themes from observations notes and the exit interview. There are several implications from the data. The reason articles were selected for discussion determines the results of the discussion. Teachers experience a deeper motivation to study their subject material, and greater enjoyment when they discuss their lessons. Teachers benefit from having a shared curriculum and a common language. The benefit teachers experienced from participating in professional discussions is greater than the time and effort it takes to prepare for them.

description: Babies who are born with hearing loss have historically missed out on early language acquisition opportunities due to delayed diagnosis. Over 95% of deaf children are born to hearing families who would have no reason to suspect a hearing loss until typical language development is not evidenced (Marschark, 2010). Unfortunately, a dearth of language acquisition in early childhood has damaging affects on any subsequent language learning as well as social and emotional development. By waiting until children are of an age to evidence this lack of language, their overall language capability is already impeded, and the consequences of this delay will manifest throughout the child’s lifetime (Mayberry, 2009; Moeller, 2000; Watkins, 1987; Yoshinaga-Itano, 2003).

title: Research Treatments for Self Injurious Behavior with Unclear or Automatically Reinforced Causes and their Correlation to Least Restrictive Behavioral Interventions
Creators: name: Blamires, Valarie
Publisher: name: Utah State University
Year: 2002

description: Self injurious behavior (SIB) is one of the most perplexing and frightening behaviors exhibited by some students. SIB is defined as behavior wherein the individual is engaging in repetitive or stereotypical behaviors that may and in some cases does result in physical harm to the individual (Jacob-Timm, 1996). The behaviors are displayed in a variety of topographies. They can range from fingernail picking to head banging, and can be so destructive that the student can cause severe injury to themselves or even death. Individuals who display this type of behavior also display a variety of medical and clinical diagnosis which may include Lesch-Nyhan Syndrome, Down Syndrome, Autism, Cornelia de Lange Syndrome and Cerebral Palsy.

description: We study the physical properties of three clusters of galaxies, selected from a BeppoSAX Wide Field Camera (WFC) survey. These sources are identified as 1RXS J153934.7-833535, 1RXS J160147.6-754507, and 1RXS J081232.3-571423 in the ROSAT All-Sky Survey catalogue. We obtained XMM-Newton follow-up observations for these three clusters. We fit single and multi-temperature models to spectra obtained from the EPIC-pn camera to determine the temperature, the chemical composition of the gas and their radial distribution. Since two observations are contaminated by a high soft-proton background, we develop a new method to estimate the effect of this background on the data. For the first time, we present the temperature and iron abundance of two of these three clusters. The iron abundance of 1RXS J153934.7-33535 decreases with radius. The fits to the XMM-Newton and Chandra data show that the radial temperature profile within 3' towards the centre either flattens or lowers. A Chandra image of the source suggests the presence of X-ray cavities. The gas properties in 1RXS J160147.6-754507 are consistent with a flat radial distribution of iron and temperature within 2' from the centre. 1RXS J081232.3-571423 is a relatively cool cluster with a temperature of about 3 keV. The radial temperature and iron profiles suggest that 1RXS J153934.7-833535 is a cool core cluster. The Chandra image shows substructure which points toward AGN feedback in the core. The flat radial profiles of the temperature and iron abundance in 1RXS J160147.6-754507 are similar to the profiles of non-cool-core clusters.

title: Electronic Analog Computer Hydrologic Simulation of the Upper Bear River Basin
Creators: name: Basha, Mohammed A.
Publisher: name: Utah State University

description: OF the total precipitation falling on watersheds throughout the world, an average of approximately 85 percent returns directly to the atmosphere through evaporation and use by mountain vegetation. The remaining 15 percent moves from the watersheds as runoff and becomes available in the valleys to be used by man for irrigation, industry, recreation, and many other requirements in recent years has led to an increasing need for efficient management of available water resources, and in this regard computer modeling or simulation has proved to be a powerful tool.
The study described herein involves simulation of the hydrologic system of the upper Bear River Basin by means of an electronic analog computer. The various processes within the model are linked by the continuity of mass principles, which requires a hydrologic balance at all points. The analog computer is ideally suited to the soluation of the time-dependent differential equations of the model and to the trial and error process required during testing and verification.
The primary objectives of the present study are: (i) to develop, using an analog computer, a simulation model of the hydrologic system of the upper Bear River Basin; and (ii) to demonstrate the applicability of the simulation model to water resource planning in the Bear River Basin by evaluating various alternative management possibilities subject to selected constraints.
A brief review of computer modeling is included in Chapter II. The development of the hydrologic and the corresponding analog computer model of the upper Bear River Basin is detailed in Chapter III. Results of the study are included in Chapter IV. Conclusions and limitations are mentioned in Chapter V. Finally, brief summary and recommendations for additional studies are presented in the last chapter of this report.
Tracce di cinefilia su Facebook
Traces of cinephilia on Facebook

description: La mia tesi approfondisce le dinamiche della cinefilia su Facebook: quali relazioni s'instaurano tra lo spettatore cinefilo, e dunque il suo particolare sguardo, e la moltitudine di frammenti di cinema dispersi nella rete; come si sono modificati i rapporti, gli atteggiamenti, i processi di negoziazione, le abitudini e soprattutto i discorsi dei cinefili al cospetto di tracce di cinema sui social network e in particolare su Facebook. Inoltreprovo a dimostrare che la cinefilia è un'esperienza costitutivamente autobiografica, cui il web permette il perpetuare potenzialmente infinito della (auto)narrazione di sé.
description: My thesis aims at analyzing the relations that occur between the cinephile member of the audience and the multitude of cinema fragments that populate the web. In addition, I'll investigate the way in which relationships, behaviors, processes of negotiation, and habits of cinephiles have been modified by the encounter with on-line cinema traces: the definition of the various typologies of classic/traditional cinephile behaviors; the mapping of the contemporary on-line behaviors of cinephilia: status updates, video uploads, creation of fan-pages and of bottom-up groups, etc; creation of fan-groups and of groups with the purpose of advertising Festivals and studios; diffusion of reviews and usage of one’s own “wall” to publicize personal reviews, etc. The massive development of the systems of on-line social networking highlight the emergence of new and ambiguous figures of cinephiles. Whilst these contemporary figures maintain some characteristics deriving from the evolution of classic cinephilia, on the other hand they show completely original typologies of experience, socialization and taste. The web, and in particular the programs of video sharing and the social networks, feed and trigger the characteristics of classic cinephilia, amplifying its consequences: the unity of the film-text has been definitively compromised, for cinephilia can now overcome the boundaries of the dark élite-oriented cinema halls. A one and a half hours long movie can now be watched in pieces, it can be arbitrarily reconstructed, its scenes can be shared on YouTube according to one’s taste and preferences, it can be preliminarily evaluated by having watched nothing but a fragment of it being shared by a friend on Facebook, whereas the varieties of video shared by a friend on Facebook can help one understanding that friend. In the study of contemporary culture, cinephilia helps understanding some of the internet-related phenomena, such as video sharing websites and social networks.

description: Teachers have the difficult job of creating an educational climate in which subjects are linked and system are mutually dependent. Watershed education affords teachers thi s opportunity by using water quality monitoring as a basis for the study of any academic subject. A Ri ver Run Through Us: The Bear River Watershed Education Project (BRWEP) is a student-based program in Utah, Wyoming, and Idaho. The program aims to increase understanding and concern for the Bear River watershed by engaging students in water quality monitoring. Based on our experi ence in creating, managing, and evaluating this program, a process model for watershed education was developed. The model describes how to organize resources, enli st parti cipants, train and support them. and evaluate the program. This information can be used by watershed education practitioners to implement similar programs in other basins. In its first two years, BRWEP has been particularly effecti ve at developing support materi als and trai ning teachers in water qu ality monitoring. A formative program evalu ation was conducted to illu minate ways that the program could be improved. The results suggest th at BRWEP administrators can better assi t teachers with creating an interdi sciplinary curriculum, provide teachers with more content knowledge, and devise ways to allow schools to increase their participation time. In addition to the model and eva luation, I present a multi-scalar analysis of volunteer monitoring, discuss the relevant literature, and offer a series of recommendations to improve BRWEP.

description: Wetland Wonders Field Experience Program (WWFEP) at the Bear River Migratory Bird Refuge connects U.S. Fish and Wildlife Service conservation and education goals with an educational need (understanding wetlands) in the Great Salt Lake Ecosystem by using innovative education and volunteer initiatives. The WWFEP has two principal components, the Education Program Module (EPM) and the Volunteer Instructor Module (VIM).
The EPM provides a well rounded environmental educational experience to third, fourth and fifth grade students based on constructivism, inquiry-based learning, subject integration and theoretical model of environmental education. Third graders study Wetland Creatures (adaptations and habitats), fourth graders study the Wetland Ecosystem (abiotic and biotic relationships), and fifth graders study the Great Salt Lake Watershed (wetland function, threats, and management). The EPM is divided into three lesson components: the pre-field, field, and post field. The pre-field component includes the use of student directed learning centers (discovery drawers) in the classroom to engage and teach students about the refuge, reducing the need for teacher-driven pre-site lessons. The field component is a 4-hour, station centered visit to the refuge where students acquire knowledge and awareness about wetlands through hands-on activities. The post-field component consists of a 1-hour classroom visit that unites the entire experience by reviewing field content and applying learning to a relevant wetland conservation problem.
The VIM provides a protocol for recruiting and training parents and community members to teach the field component of the program, which reduces refuge planning and staffing pressures. The WWFEP was field-tested in spring 2002 at two elementary schools in the Box Elder School District. Teacher, students, and volunteers were formally and informally evaluated. Overall, evaluations indicated that the EPM and VIM were well organized and well received. Evaluation comments noting deficiencies in content and/or structure were used to improve the final version of the WWFEP.
