The effects of acid-base disturbances on branchial and renal calcium fluxes in the freshwater rainbow trout (Oncorhynchus mykiss).
Creators: name: MacKenzie, Wendy Marlene.
Publisher: name: Université d'Ottawa / University of Ottawa

Subjects: subject: Biology, Animal Physiology.

description: Whole body calcium influx, branchial calcium efflux, and renal Ca$\sp{2+}$ excretion were measured in rainbow trout (Oncorhynchus mykiss) either exposed to environmental hypercapnia or infused intra-arterially with NaHCO$\sb3$. These experiments were performed to assess the potential impact on Ca$\sp{2+}$ balance of the changes in gill morphology that are known to accompany acid-base disturbances in this species. After 48 hours of environmental hypercapnia, gill filamental chloride cell fractional area was significantly reduced. Despite this reduction, and the presumed involvement of the chloride cell in calcium influx, whole body calcium influx was increased after 12 hours of hypercapnia and remained elevated for 48 hours. Branchial calcium efflux was unaltered during hypercapnia exposure, whereas renal Ca$\sp{2+}$ excretion was elevated over preflux values only at 6 hours of hypercapnia. Measurement of the kinetics of whole body calcium influx after 48 hours of hypercapnia revealed a significant increase in the maximal uptake rate of Ca$\sp{2+}$ yet the affinity constant of Ca$\sp{2+}$ uptake was unaffected. Measurements of high-affinity. Ca$\sp{2+}$-ATPase activities and ATP-dependent Ca$\sp{2+}$ transport of gill basolateral membrane vesicles revealed that the ATP-dependent Ca$\sp{2+}$ extrusion mechanism of the gills was not affected by hypercapnia. The results of this study clearly show that the reduced chloride cell surface area that accompanies hypercapnia in trout does not impair calcium homeostasis. Whole body Ca$\sp{2+}$ influx was significantly increased after 6 hours of NaHCO$\sb3$ infusion and remained elevated throughout the duration of the experiment. Branchial and renal Ca$\sp{2+}$ effluxes were largely unaffected by NaHCO$\sb3$ infusion. Plasma total Ca$\sp{2+}$ concentrations were significantly decreased after 6 hours of NaHCO$\sb3$ infusion and remained so until 48 hours. (Abstract shortened by UMI.)

description: Background: Chronic traumatic encephalopathy (CTE) is an enigma that has become synonymous with combat sports over the past few decades. Mixed martial arts (MMA) is a combat sport that is growing in popularity world-wide. The objective of this study is to determine the factors associated with head trauma among MMA athletes. Methods: Logistic regression analyses using SPSS 20 was employed to model putative covariates against the dichotomous outcomes of unconsciousness (for the full dataset) and diagnosed concussion (for the enriched subset of fighters who were rendered unconscious). Results: Increasing age, black or African-American ethnicity, shorter rest periods between fights, increasing numbers of significant clinch strikes landed, significant distance body strikes landed and power strikes landed to the body at distance are all factors associated with being diagnosed with a concussion among the fighters rendered unconscious. Conclusion: If bolstered by confirming laboratory and clinical evidence, policies should be developed for implementation by MMA governing bodies to help reduce incidences of head trauma and concussion, built around fighters’ demographic and behavioural characteristics. In particular, enforcing a mandatory rest period between fights and placing an upper limit on fighters’ age are ideas worth exploring.

description: Indoor localization is the process of localizing people or objects inside a building in the same way GPS does in an outside environment. In recent years, researchers have successfully achieved improvement in indoor localization accuracy. Still there are many limitations to overcome in performing and achieving good accuracy in indoor localization. The interest in estimating the location of something inside a building with good accuracy is very strong. In this thesis we first propose an indoor localization technique relative to Wi-Fi access points along with a novel heuristic search based algorithm, named MuSLoc. Through simulation and comparative studies, we have shown that MuSLoc outperforms other indoor localization models without the help of fingerprinting or crowdsourcing about the environment. MuSLoc provides almost the same accuracy in LOS (Line of Sight) and NLOS (Non-Line of Sight) environments with regular infrastructure that has recently been provided by smart phones. This model doesn't require any additional hardware support in order to perform well. Further, we propose another indoor localization based Wi-Fi device tracker model, named MSTracker, which is able to track both moving and non-moving devices inside a building. This model is also free from specialized infrastructure and can perform well without any training data information. Through real time simulation and analysis we have shown that it performs more accurately than other available models. Through extensive simulations in a real time environment and analysis of performance comparatives with other available models, we have shown that both MuSLoc and MSTracker perform more accurately with COTS than any other method of indoor localization and tracking of objects inside a building. The complete package of MuSLoc and MSTracker can perform perfectly with recently available Wi-Fi modules and smartphones.

description: Il presente intervento ha lo scopo di mettere a fuoco alcune questioni di fondo sulla didattica del melodramma e di formulare alcune ipotesi metodologiche approfondite nel volume Insegnare il melodramma: saperi essenziali, proposte didattiche, finanziato dall’Università della Valle d’Aosta e destinato ad insegnanti della scuola di base, dalla scuola dell’infanzia alla secondaria superiore. Il libro è suddiviso in due parti: la prima di riflessione teorica e metodologica; la seconda più operativa, e contenente alcuni percorsi didattici divisi per fasce scolastiche. Esso dunque intende fornire a chi opera nella scuola una riflessione articolata e almeno un po’ approfondita sull’opera lirica, e nel contempo degli strumenti di lavoro concreti. Si può constatare infatti che alcune recenti pubblicazioni sulla didattica dell’opera puntano sull’immediata operatività (anche ai livelli più precoci d’istruzione), ma difettano, a nostro avviso, di un’adeguata cornice teorico-metodologico-concettuale: il che si ripercuote anche sul livello e sulla qualità dei percorsi didattici stessi.

Socio-cultural barriers to female entrepreneurship in rural areas

Publisher: name: Zenodo

description: This paper explores the socio-cultural barriers that hinder female entrepreneurship in rural Morocco, drawing on institutional and social role theories to understand how institutional and cultural factors influence women's economic choices. The study aims to provide an analysis of the constraints and opportunities in a context marked by rigid social norms and structural limitations, while suggesting ways to improve the empowerment of rural women. The data used in this study come from a sample of 272 women living in rural areas of Morocco. These women were selected to represent diverse profiles in terms of age, education level, and marital status, in order to capture the multiple dimensions of the entrepreneurial challenges they face. The study adopts an empirical approach based on an Ordered Probit model, appropriate for the ordinal nature of the dependent variable measuring the degree of entrepreneurial readiness. The results reveal that cultural expectations and social pressures constitute significant obstacles to female entrepreneurship in rural areas. Traditional roles and community norms have a strong negative effect on women's entrepreneurial engagement. Additionally, geographic mobility limitations restrict access to resources and opportunities, while access to social and economic networks is partially influential. On the other hand, increased access to financial and institutional resources emerges as an important factor promoting entrepreneurship. The study also highlights that education plays a positive role, while marital status, particularly for divorced women, is associated with a higher propensity to engage in entrepreneurial activities.
Écologie chimique et ethnobotanique de Momordica charantia L. (Cucurbitaceae) au Togo, Afrique de l'Ouest.

description: Momordica charantia L. (Cucurbitaceae), a traditionally used medicinal plant, was the subject of chemical ecology and ethnobotany studies in Togo, West Africa. Momordicins I and II present in leaves were quantified with a novel HPLC method. Environmental factors which are significantly and positively correlated to momordicin content include light intensity and parameters related to drier habitats. These results are consistent with growth-differentiation balance and carbon/nutrient balance theories. Genotypic variation is significant. The Togolese population use M. charantia mainly for stomach aches, chickenpox and measles. Utilization consensus exists between ethnic groups and also between the population and traditional healers. Traditional knowledge of biological activities is confirmed by positive antiviral and anthelminthic activities of leaf ethanolic extracts. Moreover, harvesting criteria used by traditional healers suggest evidence of a certain comprehension of the plant natural chemical ecology.

description: La tavola rotonda ‘L’opera monta in cattedra: didattica del melodramma’, coordinata da Lorenzo Bianconi e Annamaria Cecconi nel novembre 2007 in occasione dell’XI Colloquio di Musicologia del «Saggiatore musicale», includeva un mio breve intervento sull’esperienza didattica maturata in moduli d’argomento operistico nell’Università di Oxford, dove ho insegnato dal 1998 al 2008. L’intento era di fornire dati utili a un esercizio comparativo, il quale permettesse d’osservare le esperienze di docenti sia d’università sia di conservatorii italiani dalla prospettiva d’un sistema universitario molto diverso da ambo le istituzioni e che però, come vedremo, per le sue caratteristiche pare collocarsi a cavallo tra le due. Le pagine che seguono costituiscono un ripensamento sistematico di quelle riflessioni, nella speranza che esse possano tuttora risultare di qualche interesse a chi riflette sulla didattica del melodramma in Italia. Dopo aver delineato in breve il contesto istituzionale, presenterò un questionario proposto a due gruppi di studenti; sui risultati esporrò poi qualche riflessione conclusiva, tenendo presenti i temi proposti dal testo-base della tavola rotonda e la discussione che ebbe luogo a Bologna. Avverto infine che, benché io scriva quasi sempre al presente, ciò che dico si riferisce al periodo del mio insegnamento oxoniense: dal 2008 alcune cose possono essere cambiate.

description: The New World (USA, 2005) è il titolo del quarto lungometraggio del regista americano Terrence Malick. Il film narra la leggendaria storia d’amore fra la principessa Pocahontas (Q’orianka Kilcher), della tribù dei Powathan, e il soldato ed esploratore inglese John Smith (Colin Farrell), sullo sfondo delle vicende della fondazione di uno dei primi insediamenti europei sul Nuovo Continente all’inizio del secolo XVII. L’argomento specifico del percorso didattico che qui si propone, rivolto a una classe seconda o terza della Scuola secondaria di primo grado,  consiste nell’analisi di alcune sequenze filmiche accomunate dall’impiego del tema del secondo movimento (Adagio) del Concerto per pianoforte e orchestra K 488 di Wolfgang Amadé Mozart. Il percorso didattico si basa su un’attività di analisi audiovisiva, vòlta a favorire l’apprendimento di categorie, concetti e strumenti che possano arricchire le strategie di lettura di una tipologia di testo – il testo sincretico cinematografico – che tiene un posto di spicco nella produzione e nel consumo musicale contemporanei. L’opera di Malick, oltre che costituire un raffinato esempio d’impiego della musica nel film, ha anche il merito di affrontare un tema di grande significato storico, l’incontro tra Nuovo e Vecchio Mondo, particolarmente adatto a promuovere una riflessione sulla diversità culturale e sul dialogo interetnico.

Subjects: subject: Health Sciences, Mental Health.

description: Caregiver burden has been studied at length in caregivers of many populations of chronically ill people. The other side of the informal caregiving relationship is the recipient's response to aid, especially their perceptions of the burden they pose to their caregiver. This is referred to as self-perceived burden, and has rarely been studied from the patient's point of view. Strong feelings of being a burden may be an important emotional factor influencing adjustment to illness, compliance with physician's orders, utilization of health-care resources and end-of-life decision-making. The current study advances the current understanding of self-perceived burden through the development and preliminary validation of the Self-Perceived Burden Scale. Through the course of this study, we have developed a valuable screening instrument for feelings of being a burden. It is brief, easily self-administered, and reliably identifies individuals in emotional distress due to feelings of being a burden on others. (Abstract shortened by UMI.)

description: Cutaneous T-cell lymphomas (CTCL) are the most common primary lymphomas of the skin. We have previously identified thymocyte selection-associated high mobility group (HMG) box protein (TOX) as a promising drug target in CTCL; however, there are currently no small molecules able to directly inhibit TOX. We aimed to address this unmet opportunity by developing anti-TOX therapeutics with the use of computer-aided drug discovery methods. The available NMR-resolved structure of the TOX protein was used to model its DNA-binding HMG-box domain. To investigate the druggability of the corresponding protein–DNA interface on TOX, we performed a pilot virtual screening of 200,000 small molecules using in silico docking and identified ‘hot spots’ for drug-binding on the HMG-box domain. We then performed a large-scale virtual screening of 7.6 million drug-like compounds that were available from the ZINC15 database. As a result, a total of 140 top candidate compounds were selected for subsequent in vitro validation. Of those, 18 small molecules have been characterized as selective TOX inhibitors.

Development and implementation of novel numerical techniques for integrated optics and microwave planar structures.

Subjects: subject: Engineering, Electronics and Electrical.

description: In this thesis, a novel numerical method for characterizing the electromagnetic modes supported by multilayer planar optical waveguides and a new formulation of the Method of Lines (MoL) for the static analysis of multi-conductor planar transmission line structures have been developed. One purpose of this work is to develop an efficient and accurate numerical method to analyze planar lossless, lossy and active optical waveguides in anisotropic media. This method solves the dispersion equation in the complex plane via Cauchy's integration for a guided wave structure of interest. The method is applicable to lossless, lossy, active and ARROW waveguide structures and can handle both leaky and guided modes. Contrary to the methods currently published in the literature, which are based on a numerical derivative of the dispersion equation, we propose an analytical derivative for the latter. This has a double impact: improved accuracy and reduced CPU time. The specific integration contour for leaky modes is discussed. The results are in excellent agreement with several results published in the literature. Another purpose of this work is to develop a new formulation useful for modeling the Quasi-TEM performance of multi-conductor transmission lines in inhomogeneous anisotropic media, including finite metallization thickness. A general Method of Lines (MoL) formulation for inhomogeneous anisotropic media and finite metallization thickness is derived. The method allows the accurate determination of the static parameters of the transmission line with great efficiency compared to methods available in the literature. Several numerical examples are shown for single and multi-conductor transmission lines including finite metallization thickness effect. Comparisons made with the results available from the literature validate the approach.
Identity-based security solutions for mobile ad hoc networks

description: In this thesis, we propose security solutions for pairwise and broadcast communication in mobile ad hoc networks. We use identity-based keys that do not require certificates and that simplify key management. We use pairwise symmetric keys that are computed non-interactively by the nodes, which reduces communication overhead. Our pairwise-key management protocol requires a minimum number of keys, O(N), to be generated by the third party as compared to the conventional pairwise schemes with O(N2). We also propose an efficient identity-based signature scheme for an authenticated broadcast protocol, a collision-free method for computing broadcast keys, a key escrow free scheme and a signcryption scheme as an alternative to our signature-encryption algorithm for broadcast protocol. Since in the group key distribution in mobile ad hoc networks there is the possibility of packet loss due to the mobility of users and wireless channels, we also propose self-healing, mutual-healing and some optimization techniques for the recovery of lost session keys.
The stability of anodic oxide films on gold and the difference between their interfacial capacitance and that at the Au-metal surface

Publisher: name: Université d'Ottawa / University of Ottawa

Subjects: subject: Chemistry, Physical.

description: In studies of processes at oxidized compared with unoxidized electrode surfaces by transient methods, corrections for double-layer charging are usually required and have often been made by extrapolation of double-layer capacitance (Cdl) data for the metallic surface, e.g. at Au or Pt, into the potential region of oxide-film formation. Voltammetry and impedance spectroscopy provide direct information on Cdl values determined at unoxidized, i.e. metallic, Au surfaces compared with those of anodic oxide films generated potentiostatically to various extents that are stable in time, and characterized by reductive linear-sweep voltammetry. Using Electrochemical Impedance Spectroscopy, Cdl is derived from constant-phase element (CPE) values and the CPE parameter, ϕ, which is found to be near unity for most conditions. In the second part of this thesis, the stability of the compact, so-called alpha-oxide film on gold electrodes in contact with halide solutions was investigated by means of voltammetry coupled with nanogravimetry, using an EQCN.

description: This paper explores infrastructure as a type of landscape and landscape as a type of infrastructure. The hybridisation of the two concepts, landscape and infrastructure, seeks to redefine infrastructure beyond its strictly utilitarian definition, while allowing design disciplines to gain operative force in territorial transformation processes. This paper aims to put forward urban landscape infrastructures as a design concept, considering them as armatures for urban development and for facilitating functional, social and ecological interactions. It seeks to redefine infrastructural design as an interdisciplinary design effort to establish a local identity through tangible relationships to a place or region. Urban landscape infrastructures can thereby be used as a vehicle to re-establish the role of design as an integrating practice. This paper positions urban landscape infrastructure design in the contemporary discourse on landscape infrastructures. The space of flows, as opposed to the space of places, is introduced as an impetus to develop the concept of landscape infrastructure into a more comprehensive form of urban landscape architecture. Furthermore, this paper outlines a set of principles typical for urban landscape infrastructure design and suggests three potential fields of operation: transport, green and water landscape infrastructure. The design of these operative landscape structures is a crosscutting field that involves multiple disciplines in which the role of designers is essential.

description: There is limited data on virologic outcome and its correlates among HIV-infected children in resource-limited settings. We investigated rate and correlates of virologic outcome among treatment naïve HIV-infected Ethiopian children initiating cART, and were followed prospectively at baseline, 8, 12, 24 and 48 weeks using plasma viral load, clinical examination, laboratory tests and pretreatment HIV drug resistance (PDR) screening. Virologic outcome was assessed using two endpoints–virological suppression defined as having “undetectable” plasma viral load < 150 RNA copies/mL, and rebound defined as viral load ≥150 copies/mL after achieving suppression. Cox Proportional Hazards Regression was employed to assess correlates of outcome. At the end of follow up, virologic outcome was measured for 110 participants. Overall, 94(85.5%) achieved virological suppression, of which 36(38.3%) experienced virologic rebound. At 48 weeks, 9(8.2%) children developed WHO-defined virological treatment failure. Taking tenofovir-containing regimen (Hazard Ratio (HR) 3.1-[95% confidence interval (95%CI) 1.0–9.6], p = 0.049) and absence of pretreatment HIV drug resistance (HR 11.7-[95%CI 1.3–104.2], p = 0.028) were independently associated with earlier virologic suppression. In conclusion, PDR and cART regimen type correlate with rate of virologic suppression which was prominent during the first year of cART initiation. However, the impact of viral rebound in 38.3% of the children needs evaluation.
The rigidity transition in a short-chain polymer glass

description: In this thesis, we present a thorough investigation into the rigidity of a polymer melt above and below its glass transition (GT) at a temperature TG = 0.465 (in reduced Lennard-Jones units). We use an isothermal-compression method to enter the glassy phase and NPT ensemble is realized through molecular dynamics simulations. We monitor such quantities as the mean-square displacement, the heat capacity CP, the volume and time-dependent shear modulus G(t). Whenever possible, these quantities are monitored below the GT as well. We also compute the shear modulus mu via external deformations and, in the zero-shear limit, find reasonably good agreement with G(t → infinity). The rigidity transition (RT) in the system is found to occur slightly below the GT at a temperature TR = 0.44. The results are explained in terms of sufficient free volume above TR allowing collective motion and local stress relaxation. This is seen through dynamics which are not only heterogeneous, but also spatially correlated. We appeal to notions such as "jamming" within the system and the presence of floppy modes (which allow for deformations without energy cost) to interpret the RT phenomenon. We also characterize the response to external deformation: small and large deformation regimes can be identified, the latter type causing a non-negligible reconfiguration, an over-stretching of the chains and a move to a more shallow potential energy "well." Furthermore, we analyze the "aging" phenomenon as a series of intermittent collective rearrangements and show that the two types of instantaneous shear deformations both induce "overaging," but in two completely different manners.
Visions of Belle van Zuylen

description: This is a story about an early feminist eighteenth-century intellectual, a proposal for a mighty skyscraper on the edge of a mid-size Dutch city, a chief government architect who was trying to find arguments to save the unspoilt views of the Green Heart of Holland and a group of researchers in the Netherlands Institute for Spatial Research. Historical references, unashamedly conspicuous architecture, present-day ideas on landscape conservation and planning policy are the main ingredients of the story. Why was the view of Utrecht in 2007 more widely discussed than Vermeer's View of Delft from 1660, and why were so many officials and politicians interested in the results of a highly technical GIS-based study by an institute many of them until then had hardly heard of? As this article will make clear, even a largely academic study can have some tangible impact on a political decision-making process. In this particular case of the proposed (and controversial) Belle van Zuylen skyscraper, several seemingly unrelated facts and opinions came together. A succession of events worked in favour of the study that is the subject of this chapter: first, a proposal for an outsized building by the developer, then the rapid acceptance by a city eager to give its image a boost, followed by critical comments by the Chief Government Architect, who was backed up by his freshly installed cabinet minister. Suddenly, the skyscraper plan became something of a national issue, especially because the Green Heart of Holland, one of the most precious icons of the Dutch planning system, had come into play. In this situation, a study into the tower's visual effects was more than welcome for the policy makers involved in the decision process.

description: Haptic interfacing provides the means through which human operators can interact with virtual environments. A haptic interface contains software simulated virtual environments, controllers and haptic devices. Impedance control is investigated in this thesis from the viewpoint of suitability for haptic interface development. The difference between conventional application of impedance control in robot motion control and its application in haptic interface development is also investigated. A model based impedance control methodology was developed for haptic controller design and proved feasible for defining the interaction between a human operator and a virtual environment. The factors that could have effects to the performance of a haptic interface were also investigated experimentally using parametric studies. The investigation was carried out on a HIL (Hardware-In-the-Loop) experimental setup, which combines the real hardware and mathematically simulated components. This HIL experimental set up can be used as a generic platform for the development and testing haptic interface options before prototypes are built.

description: The heterogeneous hydrolysis of N2O5 on the surface of deliquescent aerosol leads to HNO3 formation and acts as a major sink of NOx in the atmosphere during night-time. The reaction constant of this heterogeneous hydrolysis is determined by temperature (T), relative humidity (RH), aerosol particle composition, and the surface area concentration (S). However, these parameters were not comprehensively considered in the parameterization of the heterogeneous hydrolysis of N2O5 in previous mass-based 3-D aerosol modelling studies. In this investigation, we propose a sophisticated parameterization (NewN2O5) of N2O5 heterogeneous hydrolysis with respect to T, RH, aerosol particle compositions, and S based on laboratory experiments. We evaluated closure between NewN2O5 and a state-of-the-art parameterization based on a sectional aerosol treatment. The comparison showed a good linear relationship (R?=??0.91) between these two parameterizations. NewN2O5 was incorporated into a 3-D fully online coupled model, COSMOŃMUSCAT, with the mass-based aerosol treatment. As a case study, we used the data from the HOPE Melpitz campaign (10Ń25 September 2013) to validate model performance. Here, we investigated the improvement of nitrate prediction over western and central Europe. The modelled particulate nitrate mass concentrations ([NO3-]) were validated by filter measurements over Germany (Neuglobsow, Schmücke, Zingst, and Melpitz). The modelled [NO3-] was significantly overestimated for this period by a factor of 5Ń19, with the corrected NH3 emissions (reduced by 50?%) and the original parameterization of N2O5 heterogeneous hydrolysis. The NewN2O5 significantly reduces the overestimation of [NO3-] by ?~??35?%. Particularly, the overestimation factor was reduced to approximately 1.4 in our case study (12, 17Ń18 and 25 September 2013) when [NO3-] was dominated by local chemical formations. In our case, the suppression of organic coating was negligible over western and central Europe, with an influence on [NO3-] of less than 2?% on average and 20?% at the most significant moment. To obtain a significant impact of the organic coating effect, N2O5, SOA, and NH3 need to be present when RH is high and T is low. However, those conditions were rarely fulfilled simultaneously over western and central Europe. Hence, the organic coating effect on the reaction probability of N2O5 may not be as significant as expected over western and central Europe. Quelle: https://www.atmos-chem-phys.net/
Preserving panoramic views along motorways through policy

description: Motorways were initially built outside cities, and intended to connect them. Nowadays they are an integrated part of the urban landscape. In the Dutch context of high-density land use with a scarcity of open spaces, the challenge of motorway design is shifting from attempts to fit the infrastructure into the landscape towards moulding spatial developments to fit the motorway. This is presenting policymakers with a challenge, as new motorways are rarely being constructed, while urbanisation is an ongoing process. As early as 1928, Professor J.H. Valckenier (Delft University of Technology) wrote about infrastructure’s magnetic effect on urbanisation; the fact that traffic attracts buildings seems to be a law of nature. The question is how to preserve the once so carefully designed and highly valued panoramic views from the motorway. The article sketches the background of this Dutch policy dilemma. Urbanisations along motorways have led to a cluttered landscape. Policymakers, therefore, are attempting to get a grip on urban developments along motorways, to protect the open landscape. The article provides for a definition of panorama, to provide policymakers with a basis to handle the concept of a motorway panorama. Subsequently this definition is elaborated, and a practical method is presented for identifying motorway panoramas, using GIS techniques. The article discusses the results of the identification of motorways panoramas in the Netherlands. It describes how motorway panoramas are incorporated in Dutch spatial planning. This is followed by concluding remarks. Despite the fact that this article focuses on the Netherlands, the presented method can also be applied in an international context. And although the Dutch policy agenda of wanting to prevent spatial clutter across the landscape carries a strong national connotation, the preservation of open landscapes deserves wider attention.

Subjects: piano teaching; cognition; neuroscience; virtuoso skills; grit

description: The article begins with considering what are the qualities you need in education to lead you to success? One important factor for moving from failure to success is (as also pointed out by a recent New York Time article on educational programs in general ) is the factor of 'grit’. The question of 'What is teaching about?’ is explored on the basis of three case histories: that of a middle aged music teacher, of a young performing pianist and of a cello master student. Finally, a brief historical overview of the last 50 years looks at the larger changes which have taken place in the teaching of young instrumental students. It discusses methods being used ranging from training virtuoso skills (Czerny/Cramer) to applying insights about the cognitive development (Piaget) and neuroscience to the increasingly wide range of research topics on music pedagogy today.
Honour, desire, discourse: The notion of authority in Aphra Behn's comic drama.

description: Honour, Desire, Discourse: The Notion of Authority in Aphra Behn's Comic Drama examines Aphra Behn's negotiation, within her comic drama in particular, with the notion of authority in one of England's most culturally and politically tumultuous eras. Contextualized within the sociohistory of the latter half of the seventeenth century, the paper looks in detail at three of Behn's comic plays: The Rover, or, the Banish't Cavaliers, Part I (1677), The Lucky Chance, or, The Alderman's Bargain (1686), and The Widow Ranter, or, The History of Bacon in Virginia (1689). Each study revolves around Behn's treatment of the notion of authority within the play, the particular social and political moods or events that inform this treatment, and Behn's use of the comic genre as a medium for discourse with dominant cultural paradigms.
Regulating healthy bodies: Health, medicine, and dress reform in Victorian Canada.

description: In the complex process of constructing, regulating and negotiating gender identities, the language of dress communicates messages of power and control. During the Victorian period, acceptable dress for middle-class women included wearing a long dress, corset, crinoline, petticoat, and heeled shoes. This was not a constant or fixed dress code however, and through various campaigns, attempts were made to reform women's dress. A study on change in dress, in particular, dress reform, reveals how boundaries of acceptable dress were constantly negotiated by various groups who employed clothing as a means to regulate gender, race and class. Yet, what were dress reform discourses? Who articulated them? What does dress reform reveal about gender and power relations in the nineteenth century? In this dissertation, I explore the process of problematizing dress in Victorian Canada through an analysis of discourses articulated by members of the medical community; reformers and WCTU women active in moral reform and social purity campaigns; as well as commercial retailers. Overall, this dissertation strives to enhance our understanding of the ways in which the dress reform campaign reveals attitudes towards women's bodies, behaviour and their roles in society. This dissertation argues that in Victorian Canada, it was the medical community who assumed the principle role in educating the public on healthy dress. The medical discussion on clothing covered many topics, but centered on three main themes: the need to maintain warm body temperatures through dress; the effects of tight clothing on organs; and the 'unnaturalness' of fashionable dress. The professionalization of Gynaecology and Obstetrics resulted in more physicians trained as experts on women's bodies, and by extension, on all matters related to women's lifestyle and behaviour. Thus, discourses on women's dress often constructed and reinforced a paradigm in which "fashion" was construed as a danger to women's bodies. Hence, medical discourses on women's dress went beyond placing clothing within a localized disease etiology, and addressed broader issues related to Victorian women's lifestyle, marriage and motherhood.
