Authors: Mari Massimo , Di Maio Luca , Gremigni Paola , Sommaruga Marinella , Grassi Walter
Published: June 2021

Un'efficace comunicazione č un importante indicatore della qualitŕ dei servizi ospedalieri. Questo contributo presenta i risultati di una ricerca-intervento sulle abilitŕ comunicative dei membri di un'équipe reumatologica ospedaliera dopo un corso di formazione sulla comunicazione. L'esperienza ha coinvolto ventitré operatori sanitari (78.3% femmine, etŕ media 38.3 ± 9.7 anni) della Clinica Reumatologica dell'Universitŕ Politecnica delle Marche (52.2% infermieri, 30.4% medici, 13% OSS, 4% biologi) in un corso di aggiornamento basato sulla tecnica del Gruppo Operativo di E. Pichon Rivičre. Gli operatori hanno valutato le proprie capacitŕ comunicative, prima e dopo il corso, con il Health Care Communication Questionnaire (HCCQ). Il HCCQ č stato inoltre compilato da trentatré pazienti della Clinica all'inizio del corso e da trentaquattro alla fine, per riportare l'esperienza comunicativa con gli operatori. I risultati mostrano una tendenza al miglioramento nella maggior parte delle dimensioni del HCCQ-P auto-valutate dagli operatori e un miglioramento significativo (p < 0.05) nella valutazione dei pazienti con il HCCQ. Tale risultato incoraggia la formazione degli operatori delle équipe ospedaliere nell'ambito della comunicazione con il paziente.

L'ospedale va a scuola. Un'esperienza di promozione della salute proposta dalla Scuola Ospedaliera e rivolta ai bambini della Scuola Primaria
Authors: Resca Federica , Visconti Paola , Bertana Sandra , Attanasi Paola , Gobbi Giuseppe
Published: June 2021

Data la forte attenzione al ruolo che l'ospedale e la scuola hanno in quanto soggetti promotori di salute, il presente contributo presenta un'esperienza che ha avuto l'obiettivo di promuovere l'incontro tra bambini della scuola primaria e ospedale come occasione per favorire l'attivazione di risorse e di strategie di

funzionali alla costruzione di un percorso di salute all'interno della propria storia di vita. La scuola ospedaliera č entrata nelle classi nelle quali sono state proposte attivitŕ didattiche sull'utilitŕ sociale dell'ospedale in quanto garante del diritto alla salute, sulla struttura ospedaliera, sul vissuto emotivo elicitato dall'ospedale. Successivamente ogni classe ha visitato l'ospedale, ha preso contatto con i bambini ricoverati, ha effettuato un incontro con il personale infermieristico, ha partecipato ad un incontro con una chirurga pediatra, una neuropsichiatra e una psicologa finalizzato a sensibilizzare i bambini rispetto all'attivitŕ ospedaliera e alla disabilitŕ. L'ultima fase č consistita nel riproporre ai bambini l'attivitŕ sul vissuto emotivo legato all'ospedale e un questionario di valutazione dell'esperienza, sottoposto anche alle insegnanti. I risultati vengono riportati in quanto narrazione di esperienza significativa.
Benessere psicologico e prospettiva temporale negli adolescenti e nei giovani
Authors: Zambianchi Manuela , Ricci Bitti Pio Enrico
Published: June 2021

Lo studio ha analizzato la relazione tra il benessere psicologico e la prospettiva temporale in un gruppo di adolescenti (etŕ media 16,65 anni) ed un gruppo di giovani-adulti (etŕ media 22,57 anni). Gli adolescenti sono stati suddivisi in due gruppi, media adolescenza e tarda adolescenza. Nei giovani-adulti si osserva un punteggio piů alto nella dimensione del futuro rispetto ai due gruppi di adolescenti, mentre il presente riporta un punteggio piů basso rispetto sempre agli adolescenti. Il benessere psicologico presenta anch'esso un punteggio piů elevato nei giovani-adulti rispetto agli adolescenti di entrambe le fasce d'etŕ. Sono state condotte tre analisi correlazionali separate per i tre gruppi mentre l'analisi della covarianza ha verificato l'influenza dell'etŕ sulle relazioni tra prospettiva temporale e benessere nei tre gruppi. Negli adolescenti il presente č positivamente correlato con le Relazioni Positive con gli altri e negativamente con lo Scopo di Vita e con il Benessere Psicologico generale. Nei giovani-adulti esso correla negativamente con il benessere psicologico generale. Negli adolescenti il futuro č correlato positivamente con l'Autoaccettazione, le Relazioni Positive con gli Altri, lo Scopo di Vita, ed alla Crescita Personale. Nei giovaniadulti il futuro č correlato positivamente con lo Scopo di Vita, il Dominio Ambientale, la Crescita Personale, l'Autoaccettazione, ed il benessere psicologico globale. Lo studio evidenzia la rilevanza della prospettiva temporale centrata sul futuro per lo sviluppo e l'attualizzazione delle risorse e delle potenzialitŕ nel passaggio dall'adolescenza all'etŕ di giovani-adulti e del tempo presente per la costruzione di relazioni significative unicamente nei due gruppi di adolescenti.
Tre fiumi nello stesso mare: la relazione che cura. Bateson nella psicoterapia whitakeriana ed ericksoniana
Authors: Trasarti Sponti Wilma , Rapone Anna Maria , Sevi Alessandro
Published: June 2021

- This paper puts into evidence how the works of Gregory Bateson (epistemologis,) Carl Whitaker (experiential-symbolical family therapist) and Milton Erickson (hypnotherapist) can be considered as main streams going in the same direction, thus completing themselves and enriching one another. The paper makes then a comparison of the ideas of the three Masters, utilizing mostly their original scripts, to demonstrate that their ideas con be considered congruent parts of the same story. Under this perspective Erickson and Whitaker in the microcosm of therapy room and in the process of therapeutic relationship are experientially utilizing the ecology of connecting structure typical of batesonian theory. The paper, divided into sections puts into evidence the connecting structure , the joining of patient and therapist; the unconscious;, the resources and resistances during psychotherapy, to finally land to the land of mystery, of sacred, and of change. The paper put into evidence also the similarity the three Masters have about teaching to students. Key words: change, circularity, experiential, hypnosis, mirror neurons, observation, resistance, therapeutic relationship.
La casa degli specchi. Le identitŕ di genere come processo evolutivo nella differenza e nella reciprocitŕ
Authors: Lupoi Sergio , Falchetti Mauro , Jedlowski Milena
Published: June 2021

Nella prima parte del testo gli autori provano a dare delle risposte ad una serie di quesiti riguardanti le identitŕ di genere, cercando di rintracciare i meccanismi che permettono la sopravvivenza e la trasmissione delle identitŕ (attraverso i processi relazionali), partendo da quattro dimensioni specifiche in cui si sviluppa l'essere umano: genetica, evoluzionistica, neurobiologica e antropologico-culturale. Nella seconda parte, ipotizzando l'esistenza di una trasmissione transgenerazionale dell'identitŕ di genere, gli autori si chiedono in che modo questa avvenga tra le mura domestiche e quale peso giochi la presenza di generazioni diverse nella famiglia nel creare le condizioni per un certo sviluppo del maschile, del femminile e della relazione tra i due.

Nel presente lavoro le autrici esaminano la letteratura riguardante il concetto di intimitŕ, con l'obiettivo di tracciare un percorso utile per la comprensione di come essa si costruisca all'interno della coppia. Le autrici, in particolare, attraverso le sollecitazioni derivanti da un sondaggio lanciato su un social network oltreché dalla filmografia e dalla narrativa, provano ad esaminare alcuni fattori che potrebbero essere coinvolti nella costruzione dell'intimitŕ e ad analizzare i timori ad essa connessi nella formazione della coppia.
Quando i bambini fanno da scudo ai grandi. Imparare dall'esperienza: un percorso di co-crescita
Authors: Lupoi Sergio , Francavilla Adele Maria Rosaria
Published: June 2021

In questo articolo gli autori, due terapeute e il loro supervisore, presentano un caso clinico di una famiglia monogenitoriale, madre e due bambini, seguito durante il periodo della formazione. Agli incontri di terapia partecipano anche i nonni materni, in quanto sono molto presenti nella gestione quotidiana dei bambini. In questo sistema sono i bambini a farsi carico dell'emotivitŕ di tutta la famiglia, svolgendo il ruolo di "barriera emotiva" con la funzione protettiva di impedire l'emergere di sentimenti dolorosi come rabbia, tristezza, paura, legati alla morte del papŕ. Il seguente lavoro si caratterizza per la riflessione sul processo terapeutico prendendo in considerazione i diversi livelli che si intersecano, con particolare attenzione agli isomorfismi, alla loro utilizzazione in senso evolutivo, al cambiamento della famiglia e delle terapeute e al coinvolgimento del supervisore.

- The author, after having traced a brief historical excursus related to the action-research, illustrates some approaches that, today it is possible recognize in this type of orientation to the research. Even though different are the epistemological approaches and the finalities, these manifold forms of action-research share some common principles: they are cyclical processes, centered on the problem, directed to the action and based on collaboration and participation. The author finally sets some matters. Especially in the interventions of community, it is underlined as the participation constitutes a delicate aspect; particularly she makes reference to the necessity both of a negotiation of the conflict, both of interventions directed to sustain the motivation to the participation.

Coesione sociale, senso di sicurezza e immigrazione: uno studio sui residenti italiani e stranieri della zona stazione di Reggio Emilia
Authors: Giovannini Dino , Vezzali Loris
Published: June 2021

In questo studio sono state esaminate le percezioni dei residenti italiani e stranieri dell'area stazione di Reggio Emilia rispetto al proprio contesto abitativo e alla loro qualitŕ della vita. I risultati hanno mostrato sia somiglianze sia differenze tra i due gruppi. Per tutti gli abitanti intervistati č emerso che la qualitŕ della vita č determinata dal livello di soddisfazione per la propria area di residenza e dall'intenzione di trasferirsi altrove. La coesione sociale e il senso di sicurezza risultano entrambi moderati, con conseguenze in parte diverse per italiani e stranieri, dal momento che si caratterizzano come elementi importanti associati alla qualitŕ della vita soltanto per gli stranieri. Nel contributo vengono inoltre discusse le implicazioni teoriche e pratiche dei risultati.

Amore nel transfert. Identificazione primaria e imago materna
Authors: Kohon Gregorio
Published: June 2021

In un nutrito numero di pazienti donne sembra esistere un'identificazione primaria con un'imago materna che viene vissuta solo in termini estremi. L'imago materna rappresenta una figura onnipotente, totipotente, sublime, che ispira paura, protettiva e sacra, personificando al tempo stesso una figura vulnerabile e patetica, dominata dalla tristezza, malattia e inibizione. Il ricordo inconscio del legame e delle lotte del soggetto con questa imago primaria di una madre/seno costituisce il background (mitico) contro il quale si svilupperanno in seguito le relazioni oggettuali. Queste verranno rievocate, rivisitate e ri-vissute nella situazione del transfert. Conformemente con la visione di Freud nel

Il notes magico oggi
Authors: Bertolini Mario , Neri Francesca
Published: June 2021

Gli autori discutono a partire dal lavoro di Freud sul notes magico, cosa possa oggi, anche alla luce delle recenti informazioni delle neuroscienze, intendersi per tracce mnestiche e quali differenze possano essere identificate tra queste e il ricordo. In particolare discutono l'impossibilitŕ di avere ricordi di condizioni traumatiche che percepite e memorizzate, non riescono ad essere ricordate come esperienza di sé. Per questo la ripetenza compulsiva del momento traumatico puň essere letta come impossibilitŕ di ricordo e dunque percezione ripetuta, e va riconosciuta e rielaborata nel transfert . Viene discusso un caso clinico esemplificativo.

L'autrice illustra come il processo di soggettivazione della paziente sottoposta, a un trattamento psicoanalitico a 3 sedute alla settimana, sia ostacolato da una coazione a ripetere una scelta d'oggetto fondata sulla similaritŕ che sulla differenza. L'organizzazione del Falso Sé sostiene il comportamento compiacente e quello sintomatico omosessuale e l'angoscia precoce e intensa all'estraneo risulta la matrice di comportamenti evitanti la patologica ansia di separazione e di quelli fobici nei confronti dell'Altro da sé, come il Maschile e il Paterno. Č anche presente la questione del lutto patologico, della sofferenza e del dolore della paziente per il padre da poco ritrovato e perso a seguito del suo decesso.
Challenges of navigating brands through social media
Authors: Marušić Tajana , Vranešević Tihomir
Published: June 2021

Creating and maintaining a successful brand has always been a longterm activity that required skills, knowledge, financial means and time. The success of global brands did not happen over time, and it seems that before social media there was always something precious that brand`s had – time. Time to communicate, time to create marketing campaigns, time to grow and evolve. Today, in the time of social media – there is everything but the time. Communication between consumers and brands is fast, global, and exposed for everyone to see and comment thanks to social media. Brands are more vulnerable than ever; consumers are in the position of power and now take an equal part in creating brands success. Brand management is changing, and marketing managers are faced with many challenges of navigating brands through social media. These challenges were the main idea behind the article. Explorative qualitative research was conducted by in-depth interviews of ten successful marketing managers in Croatia from various industries. From marketing agencies, food companies, the banking sector to the IT sector and direct TV sales, retail chain of sports shoes and equipment. In-depth interviews provided insight into their opinions based on experience in topics such as advantages and disadvantages of advertising on social media, measurement of advertising on social media, major challenges in brand management in a social networking environment; whether social networks and social media are synonymous or two different terms; what are the advantages and disadvantages of real-time consumer communication: and ultimately whether influencers are an indispensable variable in today’s advertising or just a passing trend. Results showed that for marketing managers in Croatia some of the advantages of social media are smart and targeted advertising, the fast possibility of reaction by brands, detailed analytics via Google and Facebook, relatively small financial expenses compared to other media such as TV, and communication with consumers in real time. The disadvantages of social media are mostly that it is an extremely sensitive platform for communication with consumers due to the positive and negative consumer comments; potential long-term consumer saturation with advertising; certain errors in communication remain forever, etc. Authors of this paper hope that it will encourage further research and discussion by enabling much-needed insight into everyday challenges marketing managers face in Croatia, as well as globally while navigating the success of brands through the dynamic and challenging environment of social media.
Exploring loyalty of generation X in a retail store context
Authors: Pavlić Ivana , Vojvodić Katija , Puh Barbara
Published: June 2021

Despite the increased interest in consumers pertained to Generation X, there is still much that is not understood about this particular market segment. In particular, this refers to their retail-related behaviour as well as the satisfaction and loyalty of customers in traditional brick and mortar retail environment. The purpose of this paper is to expand the knowledge base about Generation X’s retail store attitudes and retail behaviour in order to identify their loyalty in a retail store context. For that reason, an empirical research was carried out using a convenience sample of 153 Generation X members from the Dubrovnik- Neretva County during the period from June 1 to October 1, 2016. To analyse the data, ordinal logistic regression and ANOVA methods were used. The results revealed that several variables were found partially statistically significant, i.e. retail service quality, retail store quality, product price, product assessment, retail store format and frequency of purchase. This paper provides a framework for an improved understanding of Generation X as consumers and their overall store experience. Moreover, it contributes to the existing literature by providing new insights into the loyalty of Croatian Generation X consumers.
Durability of concrete containing ternary blends of high calcium fly ash and slag
Authors: Kandasamy Seyon
Published: June 2021

This thesis investigates the performance of ternary blends containing high calcium fly ash (HCFA) and slag against: sulfate attack, alkali-silica reaction (ASR), salt scaling, and freeze-thaw damage. In addition, compressive strength, permeability and fresh properties were evaluated. In terms of sulfate attack, the performance of HCFA was significantly enhanced when slag was added to the mix, and the same was found for ASR. The high efficacy in resisting ASR of HCFA/slag blends was found to be a result of the blends' ability to bind and retain alkalis. Regarding the salt scaling, the tested ternary concretes failed the Ministry of Transportation Ontario limit, 0.8 kg/m²; however, enhanced performance was achieved when the samples were cured by wrapping with plastic sheets. Ternary blends achieved high resistance to freezing/thawing and less bleeding compared to those of the control mix without slag or HCFA; however, setting time was dragged by about an hour.
Reading Magazines: Stefan Lorant And Picture Post, 1939-1941 : A Study Of The Picture Editor's Work From The Archive Of Modern Conflict's Collection
Authors: Cooper Hila
Published: June 2021

This thesis considers the work and influence of legendary twentieth century editor Stefan Lorant (1901-1997) for Picture Post magazine (1938-1957), during the period, 1939-1941. Comprising four chapters, this thesis commences with a literature survey covering history of photography and photojournalism texts, publications written about Picture Post, and recent scholarly writing. The second chapter centers its discussion on the first four years of Picture Post’s activity, comparing the editorial work of Lorant and Tom Hopkinson (1905-1990), who became editor in 1940. Next, “Organizing a Magazine: Structure and Content”, examines the magazine’s arrangement and composition under Lorant’s editorship. Finally, “Lorant and the Photo Essay” looks at the editor’s use of the double page spread format, considering both its content and layout. By studying Stefan Lorant’s work in the pages of the weekly, this thesis examines how a visual story was constructed during the late 1930s in the pages of Picture Post.
Exploration Of Theoretical And Application Issues In Using Fully Bayesian Methods For Road Safety Analysis
Authors: Lan Bo
Published: June 2021

The Fully Bayesian (FB) approach to road safety analysis has been available for some time, but it is largely unevaluated and untested. This study is trying to bridge the gap by conducting a thorough evaluation of FB method for black spots identification and treatment effect analysis. First, an evaluation is conducted on the univariate FB versus the empirical Bayesian (EB) method for single level severity data through the development of various models, and multivariate FB versus univariate FB for multilevel severity data, as well as the performance of various ranking and evaluation criteria for black spots identification. It is confirmed that the FB method is superior to the EB with respect to key ranking criteria (expected rank, mode rank and median rank of posterior PM, etc.). The multivariate FB method is better than univariate FB for the multilevel severity crashes.

Then a teat of the FB before-after method for treatment effect analysis is performed. Two FB testing frameworks were employed. First the univariate before-after fully Bayesian (FB) method was examined using three simulated datasets. Then multivariate Poisson log normal (MVPLN), univariate Poisson log normal (PLN) and PB (Poisson gamma) models were evaluated using two groups of California unsignalized intersections. Hypothetical treatment sites were selected from these datasets such that a significant effect would be estimated by the naive before-after method that does not account for regression to the mean. This study confirmed that FB methods can indeed provide valid results, in that they correctly estimate a treatment effect of zero at these hypothetical treatment sites after accounting for regression to the mean. Finally the EB and the validated FB before after methods were applied to evaluation of two treatments: the conversion of rural intersections from unsignalized to signalized control; and the conversion of road segments from a four-lane to a three-lane cross-section with two-way left turn lanes (also known as road diets). The result indicates that both FB and EB method can provide comparable treatment effect estimates. This would suggest it is still appropriate to conduct treatment effect analysis using the EB method for univariate crash data, but that it is essential in so doing to account for temporal trends in crash frequency.
A Full Catalogue and Analysis of Photographs and Photogravures by Robert J. Flaherty at the Art Gallery of Ontario
Authors: Chang Zulay Jau Ting
Published: June 2021

This thesis is based on a photographic collection at the Art Gallery of Ontario that comprise fifty-one photographs and photogravures by the filmmaker and photographer, Robert J. Flaherty (1884-1951). The objects consist of three groups: twenty-three photographs and nineteen photogravures of northern Arctic scenes and portraits; two
presently unattributed photographs of northern scenes that are associated with Flaherty's work of the north; and seven portraits of Canadian artists Frances Loring (1887-1968) and Florence Wyle (1881-1968) taken in Toronto, Ontario. All the photographs were taken between 1910 and 1921; the photogravures were published in 1922, in portfolios titled, Camera Studies of the Far North.
This thesis has five components: a biography of Flaherty, literature review of what is presently known about Flaherty and his photography, a brief description of Flaherty's photographs in public institutions, a full catalogue of the fifty-one objects, which is fully illustrated and includes comparative illustrations of related objects examined at the
Library and Archives of Canada in Ottawa, and an analysis of three photographs from each of the Flaherty groupings at AGO, primarily based on the research from the catalogue.
The Impact Of Alibi Change On Verdict Decision
Authors: Reynolds Kathleen
Published: June 2021

Previous research has demonstrated that a change in one's alibi is perceived as a sign of guilt. The present study aimed to determine the impact of changing one's initial alibi on ratings of guilt. One hundred and seven participants were randomly assigned to read one of four scenarios (self, police, same, and lied) that described a robbery, a suspect's initial alibi and, in all but the 'same' condition, a modified alibi. An explanation for the change was also provided. It was predicted that both alibi change and the explanation for the change would impact verdict choices. Results revealed that 51% of participants believed that the suspect was guilty regardless of condition. Alibi change predicted more guilty verdicts in the self and lied conditions. Surprisingly, participants who were more trusting were also more likely to convict. The current research contributes to the literature on the importance of alibis as it provides a greater understanding of jury decision making.
Examining the Influence of Efficacy Beliefs on Participation in a Residential Curbside Recycling Scheme: Implications for the Use of Persuasive Messaging to Promote Sustainable Behaviours
Authors: Molyneux Jocelyn Seifferth
Published: June 2021

This thesis examines participation in a household curbside recycling scheme and the influence that beliefs around the consequences of this behaviour have on participation. Using the Fishbein and Ajzen’s (2010) Reasoned Action Approach to create a model of the factors influencing behaviour, quantitative data are collected examining a variety of beliefs around the advantages and disadvantages of participation. Economic beliefs negatively correlate with behaviour while beliefs about reducing waste to landfill and preserving natural resources positively correlate with behaviour. A discussion of Ontario’s current recycling framework is also included and suggestions on areas for improvement are put forward.
An efficient architecture for discrete wavelet transform and best-basis algorithm for images
Authors: Mayilavelane Aroutchelvame
Published: June 2021

The hardware acceleration of the wavelet transform for real-time systems has become an essential research field. In the first part of the thesis, an efficient architecture that performs both forward and inverse lifting-based discrete wavelet transform is proposed. The proposed architecture reduces the hardware requirement by exploiting the redundancy in the arithmetic operation involved in DWT computation. The proposed architecture consists of predict module, update module, address generation module, control unit and a set of registers to establish data communication between predict and update modules. The symmetrical extension of images at the boundary to reduce distorted images has been incorporated in our proposed for both (5,3) wavelet and (9,7) wavelet. Best-basis algorithm that is designed for signal compression and de-noising uses WPT to select the best-basis node for a given additive cost function. In the second part of the thesis, we propose wavelet architecture to perform WPT decomposition. A new algorithm to implement the natural logarithm function using Maclaurin series is proposed to implement the cost function used for best-basis algorithm. These architectures have been described in VHDL at the RTL level and simulated successfully using ModelSim simulation environment. These architectures are implemented in Virex ll Pro FPGA series of Xilinx.
Integration of multi-constellation GNSS precise point positioning and MEMS-based inertial system for precise applications
Authors: Rabbou Mahmoud Abd
Published: June 2021

This dissertation develops a low-cost integrated navigation system, which integrates multi-constellation global navigation satellite system (GNSS) precise point positioning (PPP) with a low-cost micro-electro-mechanical sensor (MEMS)-based inertial system for precise applications. Both undifferenced and between-satellite single-difference (BSSD) ionosphere-free linear combinations of pseudorange and carrier phase measurements from three GNSS constellations, namely GPS, GLONASS and Galileo, are processed. An improved version of the PF, the unscented particle filter (UPF), which combines the UKF and the PF, is developed to merge the corrected GNSS satellite difference observations and inertial measurements and estimate inertial measurements biases and errors. The performance of the proposed integrated system is analyzed using real test scenarios.

A tightly coupled GPS PPP/MEMS-based inertial system is first developed using EKF, which shows that decimeter-level positioning accuracy is achievable with both undifferenced and BSSD modes. However, in general, better positioning precision is obtained when BSSD linear combination is used. During GPS outages, the integrated system shows submeter-level accuracy in most cases when a 60-second outage is introduced. However, the positioning accuracy is improved to a few decimeter- and decimeter-level accuracy when 30- and 10-second GPS outages are introduced, respectively. The use of UPF, on the other hand, reduces the number of samples significantly, in comparison with the traditional PF. Additionally, in comparison with EKF, the use of UPF improves the positioning accuracy during the 60-second GPS outages by 14%, 13% and 15% in latitude, longitude and altitude, respectively. The addition of GLONASS and Galileo observations to the developed integrated system shows that decimeter- to centimeter-level positioning accuracy is achievable when the GNSS measurement updates are available. In comparison with the GPS-based integrated system, the multi-constellation GNSS PPP/MEMS-based inertial system improves the latitude, longitude and altitude components precision by 24%, 41% and 41%, respectively. In addition, the use of BSSD mode improves the precision of the latitude, longitude and altitude components by 23%, 15% and 13%, respectively, in comparison with the undifferenced mode. During complete GNSS outages, the developed integrated system continues to achieve decimeter-level accuracy for up to 30 seconds, while it achieves submeter-level accuracy when a 60-second outage is introduced.

Niall Ferguson (2006), the British economist and author of The Ascent of Money: A Financial History of the World, coined the neologism “Chimerica” to identify the increasingly important and interdependent bilateral relationship between U.S. and China since Beijing emerged as the U.S.’s largest creditor and supplier of goods outside of North America. China’s contemporary cultural orientation draws primarily from Confucianism, a tradition that insists on order and cohesion. This predisposition contrasts sharply with the Aristotelian intellectual tradition of the West, and creates a constant source of friction between the two cultures. As China gains an equal economic footing with the West, and with the U.S. in particular, the sources of incommensurability between these cultures need to be understood more thoroughly to alleviate some of the conflict that would otherwise plague individual, organizational, and governmental communication spanning the two sides. This tension is evident in the editorial pages of the most important news outlets in China and the West. Focusing on selected editorials and drawing on Incommensurability Theory as an analytical framework, this research identifies some of the key cultural defaults, or commonplaces, that the Chinese government uses to guide its rhetorical position in diplomatic conflicts and the cultural roots of these default positions. 
Performance of piezoceramic sensors
Authors: Ahmed Rummaan  Syed
Published: June 2021

This study is in continuation of the previous research conducted at Ryerson University to develop a model for active monitoring of reinforced concrete members using piezo-ceramic sensor. In the previous research large concrete beam were investigated. The following study examines the performance of piezo-ceramic sensor to monitor maturity of concrete and to evaluate crack width of large base width concrete plates. Small scale beams and large scale slabs specimens were tested under three and four points bending respectively to evaluate the effectiveness of piezo-sensors at different failure modes. Test results from small scale beams were used to model correlation between concrete crack width/strains and sensor signals. The test result indicated that piezo-sensor can be used for active concrete strength monitoring at later stages. It can also be used as an effective indicator of crack width for reinforced concrete members with small base width.
Load Distribution in Precast Wide-Flange CPCI Girder Bridges
Authors: Ibrahim Magued W.
Published: June 2021

As Ontario bridge infrastructure enters the era of maintenance, rehabilitation and replacement, prefabricated bridge systems will certainly have many advantages as compared to the conventional systems. Prefabricated systems can be quickly assembled and the traffic can be opened in a very short period of time, minimizing the lane closure time, reducing the cost and design time, and minimizing forming and labour work. The Canadian Highway Bridge Design Code specifies simplified design method for slab-on-girder bridges in the form of moment and shear distribution factors. This thesis presents a parametric study, using the finite-element method, on a series of precast Wide-Flange CPCI girder bridges to examine the applicability of the CHBDC load distribution factors to this prefabricated bridge system. The parameters considered in this study include span length, number of lanes, number of girders, live load conditions, presence of intermediate diaphragms, and type of connections between individual girders. This study revealed that CHBDC load distribution factors generally overestimate the structural response of such bridges. As a result, a refined set of load distribution factor equations were developed.
Security in wireless sensor networks : implementation of Misty1 cipher in TinySec library
Authors: Mamtura Ajay P
Published: June 2021

Communication security is key to widespread adoption of wireless sensor networks. Coupling this need with the typical resource constraints encountered, TinySec was introduced by a group from UC Berkeley for the open source and highly popular TinyOS – a platform designed for wireless embedded sensor networks. Prior to this project the TinySec security implementation was provided with 2 ciphers, namely Skipjack and RC5. The library being modular in design afforded the opportunity to replace the cipher subcomponent with one of our choice, Misty1 in our case. Misty1 is a block cipher based on nested Feistel network with variable number of rounds (typically 8). It uses a 128-bit sized cryptovariable and block size of 64 bits. Designed on the basis of the theory of provable security against differential and linear cryptanalysis, the cipher is intended to allow realization of high-speed encryption on hardware platforms as well as on software environments. The new cipher implementation within TinySec was tested using 2 sample applications and run inside TOSSIM – a discrete event simulator environment for TinyOS. With the addition of Misty1, TinySec library users now have an additional choice as regards the cipher.
Improving the Prediction for the Ultimate Axial Capacity of Driven Piles in Ontario Soils with a Genetic Algorithm
Authors: Jesswein Markus
Published: June 2021

A genetic algorithm (GA) was developed to improve predictions for the ultimate axial capacity of driven piles in Ontario soils. Challenges arise to accurately predict the ultimate capacity due to many influential factors, such as the ground conditions, installation method, and pile geometry. A total of 43 piles (H or pipe piles) were collected from the Ministry of Transportation of Ontario. Side and tip resistances were extracted from piles subjected to extension and compression load tests. The soil measurements and pile resistances were regressed with a statistical analysis and GA, and the developed relationships were compared to existing design methods. On average, existing design methods overestimated the capacity by a factor of 1.16 to 3.00. The proposed correlations were slightly conservative with the capacity but provided errors within ± 30 % of the measured side resistance. The new design methods from the GA offer substantial improvements for pile design
Authority in Canadian news : an examination of the voices, perspectives and interests favoured by Canadian broadcasters
Authors: Godo Elizabeth
Published: June 2021

While the mainstream new media can be said to play a variety of roles, what is certain is its potential to inform public opinion and our understanding of the world we live in, both on a national and global scale. One of the ways this is accomplished is through the use of authority; the active decision by media outlets to invoke the trust we have in certain voices while reflecting and shaping our notions of the roles of others. When given the choice between experts, political leaders, victims, etc., all genders and cultural backgrounds, whose voices are heard in mainstream media, and as a result, whose influence is reflected in the public's understanding of the world; an understanding so crucial to a functioning democracy? Filing in the gaps in this under researched area, this thesis explores the issue of how authority plays out in the Canadian national context.
Investigation of Appropriate Model Structures for Modelling Small Urban Catchments
Authors: Ahmed Naglaa
Published: June 2021

Although the hydrologic modelling of small urban catchments has been practised for several decades, guidance on the development of models is still needed. This research evaluates and compares several modelling structures of small residential areas with and without low impact development implementation using distributed and lumped models. Hypothetical small areas were modelled to examine several grid based models with different grid sizes. The results were used to test the ability of uncalibrated models to predict runoff using three model configurations: 1) single catchment, 2) grid, and 3) homogenous areas, where every building, backyard, and street was modelled separately as a single catchment. The results of the models were compared and evaluated based on the total runoff volume, peak flow rate, and infiltration volume. The results of a real case study show that the grid model is an appropriate model structure for modelling small urban catchments.
What’s News Got to Do with It?: Examining the Contribution of Toronto’s Press in Maintaining an Environmentally-Detrimental Social Paradigm, 2003-2006
Authors: Botticella Lisa
Published: June 2021

This content analysis examines print media coverage of Toronto's waterfront development to determine whether story frames perpetuate the dominant social paradigm. Articles from 8 newspapers are analysed in two content dimensions, the sub-issues which surround waterfront development and the ways of understanding the environment presented as relevant to Toronto's waterfront development. Findings show presence of conflict, use of a non-routine information channel and broad source mix do not result in more diverse content. Likewise, characteristics such as a news organization's conventionality (i.e., alternative or mainstream), size and ownership (i.e., independent or group-owned) exert limited influence over story content. Organized around the competitive city concept described by Kipfer and Keil's (2002), this research examines whether media coverage aligns with the capitalist urbanization process, concluding story frames in news discourse de-emphasize the environment as an issue and rely on the least-progressive environment paradigms when reporting on Toronto's waterfront development.
Towards an automatic ice navigation support system in the Arctic area
Authors: Sattar Shahram
Published: June 2021

Conventional ice navigation through sea ice is manually operated by well-trained navigators, whose experiences are heavily relied upon to guarantee the ship's safety. Despite increasingly available ice data and information, little has been done to develop automatic ice navigation systems to better guide ships in sea ice. In this study firstly navigable sea areas for different types of ships were identified according to the navigation codes in northern regions. Secondly, three algorithms of path planning were adopted to automatically compute the safest-and-shortest ship routes based on the concepts of the Voronoi diagram, Visibility graph, and Visibility-Voronoi diagram, respectively. These algorithms and results were compared and evaluated in terms of different application scenarios. Results show that the Visibility-Voronoi approach seems to be the best viable solution in terms of computing performance and navigation safety. The work will provide a basis for further development towards an automatic ice navigation support system
Gender and consumerism in Nickolas Muray's photography for McCall's Magazine, 1933-1945
Authors: Roze Katherine
Published: June 2021

This thesis examines aspects of gender and consumer culture in Nickolas Muray's photographs for McCall's magazine from 1933 to 1945. It emphasizes the fluidity of meaning from image content to magazine context and includes two image indexes of Muray's images for McCall's from 1933 to 1945. One features original photographs and the other, published images. McCall's was a mass circulating women's magazine designed for the middle class homemaker. Muray's photographs for McCall's had the dual responsibility of representing the magazine's identity and the reader's idealizations. His images reflected expectations and perpetuated stereotypes of the American woman. At times, her role embodied traditional female values and at other times, it embraced modem womanhood and consumer culture. The latter was continuously amplified by the context of the magazine. These aspects of her role did not conflict. Rather, they complemented one another and characterized the diversity and limitations of her identity.
