Alleviating Negative Spillover of a Brand-Harm Crisis: Sensegiving vs. Sensehiding in a Competitor’s Denial Response Strategy

A brand-harm crisis not only affects the scandalized brand, but may also influence competing brands. Thus, marketers of competing brands need to develop response strategies for reducing negative spillover effects. This research takes a competitor’s perspective and introduces two types of response strategies used to convey a sense of denial: sensegiving and sensehiding. It also investigates how the effects of response strategies are contingent upon brand relatedness and individual thinking styles. The results from three experimental studies show that using a sensegiving strategy reduces negative spillover effects more than using a sensehiding strategy. Additionally, the studies suggest that the observed difference in the effects of response strategy tends to be greater when the level of brand relatedness is high than when it is low. However, individual thinking styles (holistic vs. analytic) seem to have little impact on consumers’ responses to the two denial strategies. This research contributes to the brand-harm crisis literature and provides novel insights into a competitor’s response to potential negative spillover effects.

Is Brand Equity an Asset or a Liability in Brand Harm Crisis? Buffering and Amplifying Effects and Contingent Conditions

Brand harm crisis often result in negative consumer responses. This thesis addresses the buffering and amplifying theoretical perspectives of brand equity effects. We theorize that brand equity may interplay with the nature of brand-harm crisis in shaping consumer reactions. Results from focus group studies provide interesting insights into the amplifying and buffering effects. Moreover, research findings from two experiment studies show that brand equity amplifies consumer negative responses in a performance-related crisis but only when the crisis is extremely severe. When the crisis becomes less severe, the amplifying effect diminishes from outset. However, in a value-related crisis, the amplifying effect of brand equity is pervasive regardless of the level of crisis severity. The current thesis adds to the extant literature by demonstrating that brand equity can have very complex effects on consumer responses, which are contingent on the severity and domain of a crisis. Theoretical and managerial implications are discussed.

Factors Contributing to Reading Performance: An In-Depth Analysis of the “Boy Crisis”

This research used a quantitative study approach to investigate the “boy crisis” in Canada. Boy crisis advocates suggest that boys are being surpassed by girls on reading assessments and promote strategies to assist male students. A feminist framework was used in this study that allowed for an investigation and discussion of the factors that mediate between gender and success at reading comprehension, interpretation, and response to text without ignoring female students. Reading scores and questionnaire data compiled by the Pan-Canadian Assessment Program were used in this research, specifically the PCAP-13 2007 assessment of approximately 30,000 13-year-old students from all Canadian provinces and Yukon Territory (CMEC, 2008). Approximately 20,000 participants wrote the reading assessment, while 30,000 students completed the questionnaire responses. Predictor variables were tested using parametric tests such as independent samples t-test, one-way ANOVA, chi-square analysis, and Pearson r. Findings from this study indicate that although boys scored lower than girls on the PCAP-13 2007 reading assessment, factors were found to influence the reading scores of both male and female students to varying degrees. Socioeconomic status, perceptions of the reading material used in language arts classrooms, reading preference, reading interest, parental involvement, parental encouragement for reading, and self-efficacy were all found to affect the reading performance of boys and girls. Relationships between variables were also found and are discussed in this research. The analysis presented in this study allows parents, educators, and policy makers to begin to critically examine and re-evaluate boy crisis literature and offers suggestions on how to improve reading performance for all students of all socioeconomic backgrounds.

Legal education in crisis: healing and humanizing Canadian law schools /

Western law schools are suffering from an identity and moral crisis. Many of the legal profession's problems can be traced to the law school environment, where students are taught to reason and practice in ways that are often at odds with their own personalities and values and even with generally accepted psychologically healthy practices. The idealism, ethic of care, and personal moral compasses of many students become eroded and even lost in the present legal education system. Formalism, rationalism, elitism, and big business values have become paramount. In such a moment of historical crisis, there exists the opportunity to create a new legal education story. This paper is a conceptual study of both my own Canadian legal education and the general legal education experience. It examines core problems and critiques of the existing Western legal education organizational and pedagogical paradigm to which Canadian law schools adhere. New approaches with the potential to enrich, humanize, and heal the Canadian law school experience are explored. Ultimately, the paper proposes a legal education system that is more interdisciplinary, theoretically and practically integrated, emotionally intelligent, technologically connected, morally accountable, spiritual, and humane. Specific pedagogical and curricular strategies are suggested, and recommendations for the future are offered. The dehumanizing aspects of the law school experience in Canada have rarely been studied. It is hoped that this thesis will fill a gap in the research and provide some insight into an issue that is of both academic and public importance, since the well-being of law students and lawyers affects the interests of their clients, the general public, and the integrity and future of the entire legal system.

Anxiety and learning / response behaviour in the context of intellectual problem solving by young children

Twenty-eight grade four students were ca.tegorized as either high or low anxious subjects as per Gillis' Child Anxiety Scale (a self-report general measure). In determining impulsivity in their response tendencies, via Kagan's Ma.tching Familiar Figures Test, a significant difference between the two groups was not found to exist. Training procedures (verbal labelling plus rehearsal strategies) were introduced in modification of their learning behaviour on a visual sequential memory task. Significantly more reflective memory recall behaviour was noted by both groups as a result. Furthermore, transfer of the reflective quality of this learning strategy produced significantly less impulsive response behaviour for high and low anxious subjects with respect to response latency and for low anxious subjects with respect to response accuracy.

Strategies for economic development in the Commonwealth Caribbean: a comparative study of the foreign economic policy strategies adopted by the Manley government in Jamaica and the Williams government in Trinidad and Tobago

This thesis compares the foreign economic poUcy dimension of the development strategies adopted by the governments of two Commonwealth caribbean countries: The Hardey government In Jamaica, and the· Williams government in Trlnidad and T ooago, The foreign economic policIes adopted by these governments appeared, on the surface~ to be markedly dissimilar. The Jamakan strategv on the one hand, emphasised self-reliance and national autonomy; and featured the espousal of radical oonaHgnment together with attempts to re-deftne the terms of the Islands externaa economIc relaUoos. The Trinidadian strategy 00 the other hand, featured Uberal externaUy-oriented growth poUctes, and close relatjoos with Western governments and financial institutions. Th1s study attempts to identify the explanatory factors that account for the apparent dlssimUarUy 1n the foreign economic policies of these two govemnents. The study is based on a comparison of how the structural bases of an underdeveloped ecooomYg and the foreign penetration and vulnerabUUy to external pressures asSOCiated wUh dependence, shape and influence foreign economic poUcy strategy. The framework views fore1gn ecooom1c strategy as an adaptive response on the part of the decision makers of a state to the coostralnts and opportunities provided by a particular situation. The · situat i 00' in this case being the events, conditions, structures and processes, associated wUh dependente and underdevelopment. The results indicate that the similarities and dissimHarities in the foreign economic policies of the governments of Jamaica and Trinidad were a reflecUon of the simHarities and dissimilarities in their respective situations. The conclusion derived suggests that If the foreign pol1cy field as an arena of choice, Is indeed one of opportunities and constraints for each and every state, then poHcy makers of smaU, weak, hlghW penetrated and vulnerable states enter thlS arena with constraints outweighing opportunities. This places effective limits 00 their decisional latitude and the range of policy options avaUable. Policy makers thus have to decide critical issues with few estabUshed precedents, in the face of domestic social and political cleavages, as wen as serious foreign pressures. This is a reflection not only of the trappings of dependence, but also of the Umned capabilities arising from the sman size of the state, and the Impact of the resource-gap In an underdeveloped economy. The Trinidadian strategy 1s UlustraUve of a development strategy made viable through a combination of a fortuitous circumstance, a confluence of the interests of influential groups» and accurate perception on the part of poUcy makers. These factors enabled policy makers to minimise some of the constraints of dependence. The faUure of Manlets strategy on the other hand, 15 iHustraUve of the problems involved tn the adoption of poUcles that work against the interest of internal and external political and economic forces. It is also tUustraUve of the consequences of the faUure 00 the part of policy makers to clarify goals, and to reconcile the values of rapid economic growth with increased self-reliance and national autonomy. These values tend to be mutuany Incompatible given the existing patterns of relations in the jnternational economy.

Impact of different irrigation strategies on grapes and wine quality of four grapevine cultivars (Vitis sp.) in cool climate conditions. An investigation into the relationships among ABA, water status, grape cultivar and wine quality

Niagara Peninsula of Ontario is the largest viticultural area in Canada. Although it is considered to be a cool and wet region, in the last decade many water stress events occurred during the growing seasons with negative effects on grape and wine quality. This study was initiated to understand and develop the best strategies for water management in vineyards and those that might contribute to grape maturity advancement. The irrigation trials investigated the impact of time of initiation (fruit set, lag phase and veraison), water replacement level based on theoretical loss through crop evapotranspiration (ETc; 100,50 and 25%) and different irrigation strategies [partial root zone drying (PRD) versus regulated deficit irrigation (RD!)] on grape composition and wine sensory profiles. The irrigation experiments were conducted in a commercial vineyard (Lambert Vineyards Inc.) located in Niagara-on-the-Lake, Ontario, from 2005 through 2009. The two experiments that tested the combination of different water regimes and irrigation time initiation were set up in a randomized block design as follows: Baco noir - three replicates x 10 treatments [(25%, 50% and 100% of ETc) x (initiation at fruit set, lag phase and veraison) + control]; Chardonnay - three replicates x seven treatments [(25%, 50% and 100% of ETc) x (initiation at fruit set and veraison) + control]. The experiments that tested different irrigation strategies were set up on two cultivars as follows: Sauvignon blanc - four replicates x four treatments [control, fully irrigated (100% ETc), PRD (100% ETc) and RDI (25% ETc)]; Cabemet Sauvignon - four replicates x five treatments [control, fully irrigated (100% ETc), PRD (100% ETc), RDI (50% ETc) and RDI (25% ETc)]. The controls in each experiment were nonirrigated. The irrigation treatments were compared for many variables related to soil water status, vine physiology, berry composition, wine sensory profile, and hormone composition [(abscisic acid (ABA) and its catabolites]. Soil moisture profile was mostly affected by irrigation treatments between 20 and 60 em depth depending on the grapevine cultivar and the regime of water applied. Overall soil moisture was consistently higher throughout the season in 100 and 50% ETc compare to the control. Transpiration rates and leaf temperature as well as shoot growth rate were the most sensitive variables to soil water status. Drip irrigation associated with RDI treatments (50% ETc and 25% ETc) had the most beneficial effects on vine physiology, fruit composition and wine varietal typicity, mainly by maintaining a balance between vegetative and reproductive parts of the vine. Neither the control nor the 100 ETc had overall a positive effect on grape composition and wine sensory typicity. The time of irrigation initiation affected the vine physiology and grape quality, the most positive effect was found in treatments initiated at lag phase and veraison. RDI treatments were overall more consistent in their positive effect on grape composition and wine varietal typicity comparing to PRD treatment. The greatest difference between non-irrigated and irrigated vines in most of the variables studied was found in 2007, the driest and hottest season of the experimental period. Soil water status had a greater and more consistent effect on red grapevine cultivars rather than on white winegrape cultivars. To understand the relationships among soil and plant water status, plant physiology and the hormonal profiles associated with it, abscisic acid (ABA) and its catabolites [phaseic acid (PA), dihydrophaseic acid (DPA), 7-hydroxy-ABA (TOH-ABA), 8' -hydroxy-ABA, neophaseic acid and abscisic acid glucose ester (ABA-GE)] were analyzed in leaves and berries from the Baco noir and Chardonnay irrigation trials over two growing seasons. ABA and some of its catabolites accurately described the water status in the vines. Endogenous ABA and some of its catabolites were strongly affected in Baco noir and Chardonnay by both the water regime (i.e. ET level) and timing of irrigation initiation. Chardonnay grapevines produced less ABA in both leaves and berries compared to Baco noir, which indicated that ABA synthesis is also cultivar dependant. ABA-GE was the main catabolite in treatments with high water deficits, while PA and DPA were higher in treatments with high water status, suggesting that the vine produced more ABA-GE under water deficits to maintain rapid control of the stomata. These differences between irrigation treatments with respect to ABA and catabolites were particularly noticeable in the dry 2007 season. Two trials using exogenous ABA investigated the effect of different concentrations of ABA and organs targeted for spraying, on grape maturation and berry composition of Cabemet Sauvignon grapevines, in two cool and wet seasons (2008-2009). The fIrst experiment consisted of three replicates x three treatments [(150 and 300 mg/L, both applications only on clusters) + untreated control] while the second experiment consisted in three replicates x four treatments [(full canopy, only clusters, and only leaves sprayed with 300 ppm ABA) + untreated control]. Exogenous ABA was effective in hastening veraison, and improving the composition of Cabemet Sauvignon. Ability of ABA to control the timing of grape berry maturation was dependant on both solution concentration and the target organ. ABA affected not only fruit composition but also yield components. Berries treated with ABA had lower weight and higher skin dry mass, which constitutes qualitative aspects desired in the wine grapes. Temporal advancement of ripening through hormonal control can lead to earlier fruit maturation, which is a distinct advantage in cooler areas or areas with a high risk of early frost occurrence. Exogenous ABA could provide considerable benefits to wine industry in terms of grape composition, wine style and schedule activities in the winery, particularly in wet and cool years. These trials provide the ftrst comprehensive data in eastern North America on the response of important hybrid and Vitis vinifera winegrape cultivars to irrigation management. Results from this study additionally might be a forward step in understanding the ABA metabolism, and its relationship with water status. Future research should be focused on ftnding the ABA threshold required to trigger the ripening process, and how this process could be controlled in cool climates.

STRATEGIES FOR PREVENTION AND TREATMENT OF HEPATITIS C VIRUS INFECTION

Hepatitis C virus (HCV) is the causative agent of Hepatitis C, a serious global health problem which results in liver cirrhosis and hepatocellular carcinoma. Currently there is no effective treatment or vaccine against the virus. Therefore, development of a therapeutic vaccine is of paramount importance. In this project, three alternative approaches were used to control HCV including a DNA vaccine, a recombinant viral vaccine and RNA interference. The first approach was to test the effect of different promoters on the efficacy of a DNA vaccine against HCV. Plasmids encoding HCV-NS3 and E1 antigens were designed under three different promoters, adenoviral E1A, MLP, and CMV ie. The promoter effect on the antigen expression in 293 cells, as well as on the antibody level in immunized BALB/c mice, was evaluated. The results showed that the antigens were successfully expressed from all vectors. The CMV ie promoter induced the highest antigen expression and the highest antibody level. Second, the efficiency of a recombinant adenovirus vaccine encoding HCV-NS3 was compared to that of a HCV-NS3 plasmid vaccine. The results showed that the recombinant adenovirus vaccine induced higher antibody levels as compared to the plasmid vaccine. The relationship between the immune response and miRNA was also evaluated. The levels of mir-181, mir-155, mir-21 and mir-296 were quantified in the sera of immunized animals. mir-181 and mir-21 were found to be upregulated in animals injected with adenoviral vectors. Third, two recombinant adenoviruses encoding siRNAs targeting both the helicase and protease parts of the NS3 region were tested for their ability to inhibit NS3 expression. The results showed that the siRNA against protease was more effective in silencing the HCV-NS3 gene in a HCV replicon cell line. This result confirmed the efficiency of adenovirus for siRNA delivery. These results confirmed that CMV ie is optimum promoter for immune response induction. Adenovirus was shown to be an effective delivery vector for antigens or siRNAs. In addition, miRNAs were proved to be involved in the regulation of immune response.

Innovation and adaptation in the Ontario grape and wine industry: An integrated, transdisciplinary response to climate change

With scientific consensus supporting a 4oC increase in global mean temperature over the next century and increased frequency of severe weather events, adaptation to climate change is critical. Given the dynamic and complex nature of climate change, a transdisciplinary approach toward adaptation can create an environment that supports knowledge sharing and innovation, improving existing strategies and creating new ones. The Ontario wine industry provides a case study to illustrate the benefits of this approach. We describe the formation and work of the Ontario Grape and Wine Research Network within this context, and present some preliminary results to highlight the opportunities for innovation that will drive the successful adaption of the Ontario grape and wine industry.
