Quality Evaluation Tool for Computer-and Web-Delivered Instruction

Abstract : The objective of this effort was to develop an Instructional Quality Evaluation Tool to help instructional developers and instructional program managers quantitatively determine the quality of their instructional products, both during development and at project completion. The Tool can also support the comparison of courseware from different developers or courseware that uses different combinations of instructional media. Likert scaling techniques were used to develop 5-point rating scales for each evaluation criterion. Anchor descriptions were developed for each rating point on all scales. This report includes these anchored Likert scales, which can serve as a "stand-alone" Tool. The evaluation criteria are organized into two major sections: instructional features and user-interface design. For those who with additional information or with to conduct a more "in-depth" evaluation, the detailed discussions of each evaluation criterion include definitions of important terms and summaries of the literature that supports the criterion. The discussions also provide suggested techniques to improve courseware by optimizing the instruction from the perspective of each criterion. Recommendations for future improvement of the Tool are provided.
On BitTorrent Media Distribution

Large-scale, real-time multimedia distribution over the Internet has been the subject of research for a substantial amount of time. A large number of mechanisms, policies, methods, and schemes have been proposed for media coding, scheduling, and distribution. Internet Protocol (IP) multicast was expected to be the primary transport mechanism for this, though it was never deployed to the expected extent. Recent developments in overlay networks have reactualised the research on multicast, with the consequence that many of the previous mechanisms and schemes are being re-evaluated. This thesis provides a brief overview of several important techniques for media broadcasting and stream merging, as well as a discussion of traditional IP multicast and overlay multicast. Additionally, we propose a number of modifications and extensions to the BitTorrent (BT) distribution and replication system to make it suitable for use in providing a streaming video delivery service, and implement parts of these in a simulator. Also, we report on a simulation study of the implemented extensions to the BT system, as well as a detailed validation study of the BT simulator itself. Furthermore, we present a comprehensive set of BT models for several important traffic characteristics, at both session and message levels.
A NOVEL INTERFACE BETWEEN LINK AND SYSTEM LEVEL SIMULATIONS

The ACTS FRAMES project has reached such a phase that a performance evaluation for the radio network can be carried out. The performance evaluation will be done for a single radio link and for the complete cellular system. Performance of a single radio link is measured by means of link level simulation and cellular capacity is measured by means of system level simulation. To get realistic system level performance figures link level performance figures have to be used as inputs for the system level simulation. In this paper, two ways, namely conventional and a novel way, to use link level simulation results within system simulations are described. Since 3rd generation mobile systems consider e.g. packet data and fast radio resource management algorithms, the conventional way to do the interface between link and system level simulations is not sufficient. Here a novel method for the interface is shown.
Sounds Of Distinction: Analyzing Socioacoustics To Map The Combinatorial Logic Of Status And Class

Music has been studied in numerous ways. Yet, there is no research which examines the link between acoustic properties of music and social processes. Three frameworks guide my research. The Homology thesis which states that elites prefer elite culture (Bourdieu, 1984); the Omnivore thesis which argues that elites are omnivores and prefer many different types of cultural objects as compared to univores (Peterson and Simkus, 1992), and the reconciliation thesis which states that elites prefer many different types of cultural objects, but they do so in ways that are patterned (Bryson, 1996). Representative samples of songs from 18 music genres form the General Social Survey are collected and acoustic features are extracted. Sixty-one percent (61%) of the songs were correctly classified into their respective genres. The misclassifications of genres represent genres which share acoustic information in meaningful ways. Network analysis reveals a structure with three spaces, popular, elite and folk. Acoustic features are then grouped into three fundamental dimensions: timbre, rhythm, loudness. Crisp genres are grouped according to four dimensions: timbre, rhythm, loudness and genre boundary. Correspondence Analysis is used to plot the musical aversions of genre sets by class and status groups. Findings indicate that respondents with increased levels of economic capital reject genre sets with strong boundaries. This study then develops 3 socioacoustic profiles which represents a respondent’s orientation towards sound. I then estimate the effects of education, income, occupational prestige, age, gender, race, religious preference, political identity, racial intolerance, political intolerance, being an omnivore and being a univore on each socioacoustic fuzzy set. Results indicate that socioacoustic

Production-Ready Global Illumination

Global illumination can provide great visual benefits, but we’re not always willing to pay the price. In production we often have constraints of time and resources that can make traditional global illumination approaches unrealistic. “Reflection Occlusion” and “Ambient Environments” have provided us with several reasonably efficient and flexible methods for achieving a similar look but with a minimum of expense. This chapter will cover how Industrial Light and Magic (ILM) uses Reflection Occlusion and Ambient Environment techniques to integrate aspects of global illumination into our standard RenderMan pipeline. Both techniques use a ray-traced occlusion pass that is independent of the final lighting. The information they contain is passed on to our RenderMan shaders where they are used in the final lighting calculations. This allows lighting and materials too be altered and re-rendered without having to recalculate the occlusion passes themselves. We will show that when used together these two techniques have given us an integrated solution for realistically lighting scenes. They allow us to decrease setup time, lighting complexity, and computational expense while at the same time increasing the overall visual impact of our images.

Remapping nominal features in the second language

This dissertation investigates second language (L2) development in the domains of morphosyntax and semantics. Specifically, it examines the acquisition of definiteness and specificity in Russian within the Feature Re-assembly framework (Lardiere, 2009), according to which the hardest L2 learning task is not to reset parameters but to reconfigure, or remap features from the way they are assembled in the L1 into new formal configurations in the L2. Within the Feature Re-assembly approach, it has been argued that re-assembling features that are represented overtly in the L1 and mapping them onto those that are encoded covertly by context in the L2 will present a greater difficulty than re-assembling features in the opposite direction (Slabakova, 2009). This dissertation examines the acquisition of four linguistic properties (types of modifiers, word order, indefinite determiners and case marking) that encode definiteness and specificity overtly or covertly in L2 Russian by English and Korean speakers. The native languages of the learners were chosen specifically in order to test various overt-covert mappings. The data obtained from two experimental tasks (grammaticality and felicity judgments) completed by 56 Russian native speaker controls, 51 Englishand 53 Koreanspeaking learners support Slabakova’s prediction that overt-to-covert realization of the feature is more challenging than covert-to-overt realization. In addition, the findings uncovered other important factors facilitating or impeding acquisition, such as the nature of the form-to-meaning mapping (one-to-one or one-to-many) and the availability of clear, unambiguous evidence for a certain mapping in the input available to learners. Results also reveal that the presence or absence of the L1 transfer depends on the overt/covert status of the feature in the L2. That is, when the feature is marked overtly in both the L1 and L2, L1 transfer has facilitative effect on the acquisition of the feature. On the contrary, when the feature is marked covertly in both the L1 and L2, L1 transfer has
Initiatives d’adoption des affaires électroniques et performance des petites entreprises

Les travaux portant sur les antecedents et l'impact d'adoption d'un e-projet par les petites entreprises (PE) sont relativement rares. De meme, les experiences reussies dans ce domaine ne sont pas tres nombreuses. Pourtant, les affaires electroniques sur Internet peuvent offrir aux PE beaucoup d'avantages et representer de nouvelles opportunites. Ainsi, cette recherche tente d'eclaircir la question suivante : comment adopter des initiatives performantes des affaires electroniques par les petites entreprises ? Afin de repondre a cette question, un modele conceptuel a ete elabore en se basant sur les travaux passes et un protocole empirique compose d'etudes de cas, d'entrevues avec des experts et une enquete par questionnaire a ete mobilise selon une methodologie pluraliste.
Les dessins noirs des salles Hillaire et du Crâne, grotte Chauvet-Pont-d'Arc : chronologie relative

Une premiere decoration prenait place sur les pendants et les parois du debut du " secteur noir ", dans les salles Hillaire et du Crâne, les ours et les hommes l'ont partiellement effacee. Un autre groupe humain a ensuite grave d'autres figures puis a nouveau dessine au fusain sur les memes panneaux et a etendu la decoration a de nouvelles surfaces. Par endroits, les superpositions sont encore visibles, a d'autres, comme sur le panneau des Chevaux, on ne devine plus que quelques gravures tandis que la derniere phase oblitere toutes les autres. La chronologie relative de certains panneaux permet de donner un nouvel eclairage a l'ensemble de la decoration de la grotte. Les datations sont concordantes, pour ce qui concerne la derniere phase (30000-32000). Le temps ecoule depuis la premiere decoration est difficilement evaluable. Des phenomenes geologiques de surface pourraient nous aider puisqu 'il semble que la paroi soit devenue plus plastique entre les deux phases.
The Effects of Block Scheduling on Student Performance

Publ ic secondary schools are i n serious trouble and may be replaced by inst itutions of choice , both publ ic and private, because our education efforts are fai l i ng to produce a work force capable of competi ng w ith those of other i ndustrial ized nations (Carrol l , 1994a) . Educators have responded to the cal l for reform by re­ structuring and rearrang ing the curricu lum, admin is­ tration , teaching techniques, and even the school day. Yet , no matter the proposed solut ion , there i s one con­ s istent recurring problem finding time to restructure . Most cures for education's i l l s involve increased t ime for traini ng, staff development , col laborat ion , com­ munication , empowerment , and student l earning . Concerni ng the issue of t ime, Sommerfeld ( 1993 ) re­ sponds aptly, "We have met the enemy, and they are hours . " I n an effort to spend the "time budget" more wisely, many schools have turned to block schedul i ng where c lasses are taught in much longer periods (n inety minutes, two hours, or even four hours per day ) . Canady and Rett ig ( 1993 ) report a number of advan­ tages to schedul i ng c lasses in longer blocks of t ime.
Humoral antimalaria immune response in Nigerian children exposed to helminth and malaria parasites

Background Malaria and helminthic parasites are endemic in tropical countries, and co-infections might influence host-parasite interactions. In this community-based cross-sectional study, the effect that the presence of soil-transmitted helminths (STH) (Hookworm, Hymenolepis nana) and Schistosoma haematobium infections could have on the immunoglobulin (Ig) candidate protein of the malaria vaccine GMZ2 levels was evaluated. Methods Blood, stool, and urine samples were collected from 5-15-year-old children to diagnose P. falciparum (Pf), STH, and Schistosoma haematobium, respectively. Identification and quantification of the parasite load of STH and S. haematobium were achieved by light microscopy. A polymerase chain reaction was carried out to detect submicroscopic infections of P. falciparum. Plasma levels of GMZ2 specific IgG and its subclasses were quantified by ELISA. Results The median level of total IgG in individuals with co-infection with Pf/H. nana was significantly lower in the mono-infected group with Pf (p = 0.0121) or study participants without infection (p=0.0217). Similarly, the median level of IgG1 was statistically lower in Pf/H. nana group compared to Pf-group (p=0.0137). Equally, the Pf/H. nana infected individuals posted a lower level of IgG1 compared to Pf-group (p=0.0137) and IgG4 compared to the Pf-group (p=0.0144). Spearman rank correlation analyses indicated positive relationships between the densities of H. nana (ρ=0.25, p=0.015) and S. haematobium (ρ=0.36, p<0.0001). Conclusions Hookworm and H. nana infections are associated with reduced GMZ2 specific IgG levels. This study shows the possible manipulation of immune responses by helminths for their survival and transmission, which may have serious implications for vaccine development and deployment in helminth-endemic regions.
The impact of submaximal fatiguing exercises on the ability to generate and sustain the maximal voluntary contraction

Neuromuscular fatigability is a failure to produce or maintain a required torque, and commonly quantified with the decrease of maximal torque production during a few seconds-long maximal voluntary contraction (MVC). The literature shows that the MVC reduction after exercises with different torque-time integral (TTI), is often similar. However, it was shown that after a fatiguing exercise, the decline in the capacity to sustain the maximal voluntary contraction for 1 min (MVC1-MIN) differs from the decrease in the capacity to perform a brief-MVC, suggesting that this latter can only partially assess neuromuscular fatigability. This study aims to highlight the relevance of using a sustained MVC to further explore the neuromuscular alterations induced by fatiguing exercises with different TTI. We used two contraction intensities (i.e., 20% and 40% MVC) to modulate the TTI, and two exercise modalities [i.e., voluntary (VOL) and electrical induced (NMES)], since the letter are known to be more fatiguing for a given TTI. Thirteen subjects performed a plantar-flexors MVC1-MIN before and after the fatiguing exercises. A similar MVC loss was obtained for the two exercise intensities despite a greater TTI at 40% MVC, regardless of the contraction modality. On the other hand, the torque loss during MVC1-MIN was significantly greater after the 40% compared to 20% MVC exercise. These findings are crucial because they demonstrate that maximal torque production and sustainability are two complementary features of neuromuscular fatigability. Hence, MVC1-MIN assessing simultaneously both capacities is essential to provide a more detailed description of neuromuscular fatigability.
Contacts et échanges entre la péninsule Ibérique et le Nord-Ouest de l'Afrique durant les temps préhistoriques et protohistoriques

L'existence de relations entre les deux continents a retenu depuis longtemps l'attention des prehistoriens et des historiens. Quelle fut l'importance des echanges et des contacts? Dans quel sens s'exercerent ces influences? Quel fut alors le role de la navigation? Enfin, quelle etait la situation du Maghreb, son etat de civilisation lors de l'arrivee des Pheniciens et des premiers Peuples de la Mer? Cette communication va s'efforcer de repondre, du moins partiellement, a ces questions.

The Use of Artificial Neural Network to Detect the Premature Ventricular Contraction (PVC) Beats

Premature ventricular contraction (PVC) is a cardiac arrhythmia that can result in sudden death. Understanding and treatment of this disorder would be improved if patterns of electrical activation could be accurately identified and studied during its occurrence. In this paper, we shall review three feature extractions algorithms of the electrocardiogram (ECG) signal, fourier transform, linear prediction coding (LPC) technique and principal component analysis (PCA) method, with aim of generating the most appropriate input vector for a neural classifier. The performance measures of the classifier rate, sensitivity and specificity of these algorithms will also be presented using as training and testing data sets from the MIT-BIH database.
ObServer: A Storage System for Object-Oriented Applications

ObServer is a storage system designed to support object-oriented applications such as computer-aided design systems, interactive programming environments and object-oriented databases. For these systems to be used effectively, the underlying storage server must support interactive transactions, provide share access to objects and perform efficiently in a distributed workstation environment. In this paper, we present the design and implementation of ObServer, consider its limitations and discuss areas of current and future research. We also provide performance statistics obtained from three types of example databases.
