The 2001 BFA Graduating Class Department of Visual Arts

One of the highlights of Grenfells annual Convocation is the exhibition of the works of the graduating class in visual arts. The exhibition gives us a priviledged glimpse into the accomplishments of our students as these have emerged directly out of their studies. By their nature, most other disciplines do not afford such a view. In a sense, then, the exhibition of works by our visual arts students represents by analogy what can be achieved in four years of intensive university study under the guidance of dedicated professionals, no matter what the field of endeavour. These particular students began with a natural ability to see and to imagine.During tha past four years, they have been challenged to build on that base talent and to develop and educate their visual imaginations. Significant creative development is never easy but the results can be inspiring. The works represent the accomplishments of all our students and provide a fresh energeticaesthetic framework within which to contemplate them.

SEEKING CULTURAL FAIRNESS IN A MEASURE OF RELATIONAL REASONING

Relational reasoning, or the ability to identify meaningful patterns within any stream of information, is a fundamental cognitive ability associated with academic success across a variety of domains of learning and levels of schooling. However, the measurement of this construct has been historically problematic. For example, while the construct is typically described as multidimensional—including the identification of multiple types of higher-order patterns—it is most often measured in terms of a single type of pattern: analogy. For that reason, the Test of Relational Reasoning (TORR) was conceived and developed to include three other types of patterns that appear to be meaningful in the educational context: anomaly, antinomy, and antithesis. Moreover, as a way to focus on fluid relational reasoning ability, the TORR was developed to include, except for the directions, entirely visuo-spatial stimuli, which were designed to be as novel as possible for the participant. By focusing on fluid intellectual processing, the TORR was also developed to be fairly administered to undergraduate students—regardless of the particular gender, language, and ethnic groups they belong to. However, although some psychometric investigations of the TORR have been conducted, its actual fairness across those demographic groups has yet to be empirically demonstrated. Therefore, a systematic investigation of differential-item-functioning (DIF) across demographic groups on TORR items was conducted. A large (N = 1,379) sample, representative of the University of Maryland on key demographic variables, was collected, and the resulting data was analyzed using a multi-group, multidimensional item-response theory model comparison procedure. Using this procedure, no significant DIF was found on any of the TORR items across any of the demographic groups of interest. This null finding is interpreted as evidence of the cultural-fairness of the TORR, and potential test-development choices that may have contributed to that cultural-fairness are discussed. For example, the choice to make the TORR an untimed measure, to use novel stimuli, and to avoid stereotype threat in test administration, may have contributed to its cultural-fairness. Future steps for psychometric research on the TORR, and substantive research utilizing the TORR, are also presented and discussed.

Die cromerzeitlichen Bären aus der Einhornhöhle bei Scharzfeld

Up to now the bear remains from the "Einhornhöhle,, Cave near Scharzfeld at the foot of the Harz Mountains have been aseribed to the species "Ursus spelaeus" without undertaking comprehensive studies. Owing to an erroneous Classification of the gravel deposits covering part of the cave floor into the Middle Terrace of the Oder Rivulet, the fossil-bearing strata have been assigned to the Eemian Interglacial. RODE, who included a part of the Scharzfeld teeth in his treatise on teeth of the bears, has stated arctoidal features in their formation apart from certain specializations. He arrived at the conclusion that the Scharzfeld Bear differs more pronouncedly from all Central European Cave Bears he had investigated than the same differ from each other, and he named the Scharzfeld Bear: "Ursus spelaeus var. hercynica". The geological exploration of the Einhornhöhle Cave and of its environs carried out by DUPHORN in 196? resulted in the aforesaid gravels pertaining to a terrace of a Pre-Elster- Glaciation age; according to DUPHORN the fossil-bearing Sediments were deposited in a Pre-Elster-Glaciation ffarm- Climate Period. The very sparse aceompanying fauna does not contain any Stratigraphie key form; arctic elements and members of an interglacial forest fauna are missing. Its composition teils in favour of a dry, yet not too cool period of the Pleistocene, which is younger than the Villa- franchium. Consequently the cave must have been taken pos- session of for settling in the Cromerian Interglacial. The investigation of the bear remains has led to the result that, in all systematically .important teeth and skeleton characteristics, the Scharzfeld Bear shows either concor- dance with Ursus deningeri or greater analogy to the same than to Ursus spelaeus; in a few properties it even appears somewhat more primitive than Ursus deningeri. Therefore the bears of the Einhornhöhle Cave belong to the species "Ursus deningeri v. REICHENAU 1906". In the frontal teeth certain specializations occur. However, in view to the great varia- bility of the deningeri-"rassenkreis" there does not seem to be a justification for establishing a subspecies of its own. Whereas up to now nothing had been known in respect of the hibernation habits of Ursus deningeri, there has for the first time been furnished proof that an Ursus deningeri population had oecologically become "cave" bears. Consequently this specialization, as the onset and cause of which the Elster Glaciation was up to now considered, must already be originating in older cold epochs.

Artificial Immune Tissue using Self-Organizing Networks

As introduced by Bentley et al. (2005), artificial immune systems (AIS) are lacking tissue, which is present in one form or another in all living multi-cellular organisms. Some have argued that this concept in the context of AIS brings little novelty to the already saturated field of the immune inspired computational research. This article aims to show that such a component of an AIS has the potential to bring an advantage to a data processing algorithm in terms of data pre-processing, clustering and extraction of features desired by the immune inspired system. The proposed tissue algorithm is based on self-organizing networks, such as self-organizing maps (SOM) developed by Kohonen (1996) and an analogy of the so called Toll-Like Receptors (TLR) affecting the activation function of the clusters developed by the SOM.

Performance Energética no contexto do sistema LEED

Com o aumento constante de procura de recursos naturais por parte dos vários setores da sociedade é urgente encontrar soluções para reduzir o seu consumo sem se travar a expansão demográfica que se tem vindo a sentir nos grandes centros urbanos. É através da implementação de medidas de sustentabilidade e pelo aumento da eficiência de utilização desses recursos que se tem vindo a combater esta tendência cada vez maior de consumismo global, sendo isto apenas possível com a implementação de ferramentas tecnológicas avançadas que permitem estabelecer limites ao considerado eficiente e premiando, em termos financeiros e de imagem de marketing, as entidades que o alcancem. O LEED é um sistema de certificação de sustentabilidade voluntário de edifícios residenciais e comerciais que estabelece métricas de comparação de parâmetros indicadores de consumos energéticos, hídricos e de materiais em todo o ciclo de vida do edifício e que tem vindo a ganhar destaque em crescendo a nível mundial. Esta dissertação teve como objetivo comparar a performance de consumo energético no âmbito do sistema LEED com a do sistema de certificação energética de edifícios nacional (SCE) de um grande edifício de serviços, estabelecendo um paralelismo de semelhanças e diferenças entre os dois e de avaliar os efeitos de potenciais medidas de eficiência energética e seus efeitos nas classificações de mérito obtidas em cada sistema. Os resultados obtidos na simulação que permitiu avaliar a performance foi muito satisfatório, tendo sido aproveitado pela empresa para efeitos de certificação LEED do edifício em estudo.

A cidade de Ulisses: literatura, mito e história

Em A cidade de Ulisses, Teolinda Gersão presta uma homenagem à cidade de Lisboa, associando, precisamente, a origem etimológica do topónimo ao mito de Ulisses. Neste trabalho, pretende-se, estudar a relação estabelecida entre Literatura, Mito e História no romance, com base na analogia que a narrativa constrói entre a figura épica de Ulisses e a caracterização de Paulo Vaz.

CIBERESPACIO: REINVENTANDO LA METÁFORA DE LO HUMANO

La pregunta sobre el humanismo está íntimamente ligada con las metáforas que las distintas sociedades en diferentes momentos han utilizado no sólo para comprender las relaciones con su entorno, sino también para estructurar su visión sobre sí mismas.En la Edad Media, el topos del microcosmos y el macrocosmos no sólo servía para reconocer en el mundo los principios de la analogía y la similitud como articuladores de las «realidades» naturales y divinas, sino que permitían una vía de interpretación de esas dos instancias en una visión totalizadora en la que la Trinidad se presentaba como metáfora por excelencia. Por otro lado, el humanismo renacentista aliviado ya de la metáfora anterior, y entusiasmado con una nueva -el hombre- se aventuró a explorar y a inventar bordes y límites por los que transitara su renovada humanidad.

Surface acoustic wave streaming in a PDMS microfluidic system: effect of frequency and fluid geometry & A remote ultrasonic glucose sensor

This thesis describes two separate projects. The first is a theoretical and experimental investigation of surface acoustic wave streaming in microfluidics. The second is the development of a novel acoustic glucose sensor. A separate abstract is given for each here. Optimization of acoustic streaming in microfluidic channels by SAWs Surface Acoustic Waves, (SAWs) actuated on flat piezoelectric substrates constitute a convenient and versatile tool for microfluidic manipulation due to the easy and versatile interfacing with microfluidic droplets and channels. The acoustic streaming effect can be exploited to drive fast streaming and pumping of fluids in microchannels and droplets (Shilton et al. 2014; Schmid et al. 2011), as well as size dependant sorting of particles in centrifugal flows and vortices (Franke et al. 2009; Rogers et al. 2010). Although the theory describing acoustic streaming by SAWs is well understood, very little attention has been paid to the optimisation of SAW streaming by the correct selection of frequency. In this thesis a finite element simulation of the fluid streaming in a microfluidic chamber due to a SAW beam was constructed and verified against micro-PIV measurements of the fluid flow in a fabricated device. It was found that there is an optimum frequency that generates the fastest streaming dependent on the height and width of the chamber. It is hoped this will serve as a design tool for those who want to optimally match SAW frequency with a particular microfluidic design. An acoustic glucose sensor Diabetes mellitus is a disease characterised by an inability to properly regulate blood glucose levels. In order to keep glucose levels under control some diabetics require regular injections of insulin. Continuous monitoring of glucose has been demonstrated to improve the management of diabetes (Zick et al. 2007; Heinemann & DeVries 2014), however there is a low patient uptake of continuous glucose monitoring systems due to the invasive nature of the current technology (Ramchandani et al. 2011). In this thesis a novel way of monitoring glucose levels is proposed which would use ultrasonic waves to ‘read’ a subcutaneous glucose sensitive-implant, which is only minimally invasive. The implant is an acoustic analogy of a Bragg stack with a ‘defect’ layer that acts as the sensing layer. A numerical study was performed on how the physical changes in the sensing layer can be deduced by monitoring the reflection amplitude spectrum of ultrasonic waves reflected from the implant. Coupled modes between the skin and the sensing layer were found to be a potential source of error and drift in the measurement. It was found that by increasing the number of layers in the stack that this could be minimized. A laboratory proof of concept system was developed using a glucose sensitive hydrogel as the sensing layer. It was possible to monitor the changing thickness and speed of sound of the hydrogel due to physiological relevant changes in glucose concentration.

Is the legal protection for the foetus adequate in clinical trials?

In 2009 and 2010, the major drug regulatory bodies, the European Medicines Agency and the Food and Drug Administration in the USA, issued requests for the generation of information relating to the absorption, distribution, metabolism, excretion, efficacy and safety of investigational drugs in pregnant women prior to approval. In the wake of thalidomide, research involving pregnant women other than for obstetric or gynaecologic purposes became rare, and studies of investigational drugs practically unknown. Consequently, none of the legislation applicable in the UK and few of the guidelines introduced in the last 40 years properly addresses the conduct of clinical trials of investigational drugs in this population. This thesis questions whether the legal protection for the foetus is adequate in clinical trials. The answer appears to be a qualified “no”. Arguments persist regarding the moral standing of the foetus, particularly regarding abortion. That will not be the intent of such trials, and a moral case is made for the conduct of clinical trials in this population by analogy with the neonate, and the pregnant woman’s autonomy. Legally, we already recognise the foetus has ‘interests’ which crystallise upon live birth, and that compensation is recoverable for harm inflicted in utero manifesting as congenital injury. The essence of research is quite different from medical practice, and the extent to which this is understood by trial participants is unclear. The approvals processes contain a number of inadequacies which have the potential to expose the foetus to harm and affect the consent of the pregnant woman. The recovery of compensation in the event of children born injured following clinical trials during pregnancy in many ways may be more complex than other personal injury cases.. The conclusions of this thesis are that the existence of a foetus does merit recognition by the law in this setting and that morally such studies are justifiable. However, the present legislation and approval processes potentially expose the foetus to avoidable risk and may not be appropriate to enable the recovery of compensation, thereby creating potential to deter future trial participants. A proposal is made regarding an approach to simplify the process for recovery of compensation, and thereby strengthen the approval and consent processes.

Relations among Topic Knowledge, Individual Interest, and Relational Reasoning, and Critical Thinking in Maternity Nursing

Critical thinking in learners is a goal of educators and professional organizations in nursing as well as other professions. However, few studies in nursing have examined the role of the important individual difference factors topic knowledge, individual interest, and general relational reasoning strategies in predicting critical thinking. In addition, most previous studies have used domain-general, standardized measures, with inconsistent results. Moreover, few studies have investigated critical thinking across multiple levels of experience. The major purpose of this study was to examine the degree to which topic knowledge, individual interest, and relational reasoning predict critical thinking in maternity nurses. For this study, 182 maternity nurses were recruited from national nursing listservs explicitly chosen to capture multiple levels of experience from prelicensure to very experienced nurses. The three independent measures included a domain-specific Topic Knowledge Assessment (TKA), consisting of 24 short-answer questions, a Professed and Engaged Interest Measure (PEIM), with 20 questions indicating level of interest and engagement in maternity nursing topics and activities, and the Test of Relational Reasoning (TORR), a graphical selected response measure with 32 items organized in scales corresponding to four forms of relational reasoning: analogy, anomaly, antithesis, and antinomy. The dependent measure was the Critical Thinking Task in Maternity Nursing (CT2MN), composed of a clinical case study providing cues with follow-up questions relating to nursing care. These questions align with the cognitive processes identified in a commonly-used definition of critical thinking in nursing. Reliable coding schemes for the measures were developed for this study. Key findings included a significant correlation between topic knowledge and individual interest. Further, the three individual difference factors explained a significant proportion of the variance in critical thinking with a large effect size. While topic knowledge was the strongest predictor of critical thinking performance, individual interest had a moderate significant effect, and relational reasoning had a small but significant effect. The findings suggest that these individual difference factors should be included in future studies of critical thinking in nursing. Implications for nursing education, research, and practice are discussed.

The twentieth century jazz piano trio: the rise of an iconic jazz paradigm

Considerando a gravação de 1947 The Bud Powell Trio como a gravação referência de trio de piano de jazz moderno, esta tese centra-se no surgimento e evolução do trio de jazz moderno cujo líder é pianista. Começando por apresentar, uma resenha dos estilos e técnicas para piano de da época pre-Powell, esta tese investiga a génese dos trios de piano jazz e examina três dos mais influeciais pianostas de jazz e lideres dos mais legendários trios de piano jazz modernos: Bud Powell, Bill Evans e Keith Jarrett. Esta tese também abordará o paradoxo inerente a um sistema democrático - a expressão própria do individuo, em justaposição com a responsabilidade para com o todo – e a sua inequivoca analogia com o gestalt do trio de piano de jazz moderno. Desde a primeira gravação de um trio de jazz com pianista como líder em 1935, o trio de jazz moderno, evoluiu tornando-se um exemplo de democracia – um contexto de igualdade em que as funções rítmicas, harmónicas, e melódicas estão igualmente distribuídas entre os três instrumentistas, que são ao mesmo tempo solistas e acompanhadores. Esta tese sublinha a eficácia do trio de jazz moderno – o seu início, e porque subsiste – baseado na sua força e beleza estética; ABSTRACT: THE TWENTIETH CENTURY JAZZ PIANO TRIO – The Rise of an Iconic Jazz Paradigm by Susan Muscarella Designating Bud Powell’s 1947 recording, The Bud Powell Trio, as the modern jazz piano trio benchmark, here, this thesis traces the emergence and evolution of the pianistled, piano-bass-drums-comprised modern jazz piano trio. Beginning with a general overview of pre-Powell jazz piano styles and techniques, this thesis investigates the earliest, most salient pre-Powell jazz piano trios, and examines three seminal modern jazz pianists and leaders of legendary modern jazz piano trios, Bud Powell, Bill Evans and Keith Jarrett. This thesis also brings to the fore the paradox inherent in a democratic system – individual self-expression juxtaposed with responsibility to the whole – and its unequivocal analogy to the modern jazz piano trio gestalt. From the earliest recording of a primarily piano-dominated piano-bass-drums-comprised jazz piano trio in 1935, the modern jazz piano trio has evolved to become a paragon of democracy – an egalitarian playing field in which rhythmic, harmonic and melodic roles are evenly distributed among all three instrumentalists who have come to serve as both soloists and accompanists.

ToLeRating UR-STD

A new emerging paradigm of Uncertain Risk of Suspicion, Threat and Danger, observed across the field of information security, is described. Based on this paradigm a novel approach to anomaly detection is presented. Our approach is based on a simple yet powerful analogy from the innate part of the human immune system, the Toll-Like Receptors. We argue that such receptors incorporated as part of an anomaly detector enhance the detector’s ability to distinguish normal and anomalous behaviour. In addition we propose that Toll-Like Receptors enable the classification of detected anomalies based on the types of attacks that perpetrate the anomalous behaviour. Classification of such type is either missing in existing literature or is not fit for the purpose of reducing the burden of an administrator of an intrusion detection system. For our model to work, we propose the creation of a taxonomy of the digital Acytota, based on which our receptors are created.
