Encounters with the Divine in the Hebrew Bible
No full textMy dissertation demonstrates the Jewish tradition’s significance for rhetoric by analyzing Biblical encounters with the divine—the ultimate Other. Thus, this dissertation responds to calls such as Steven B. Katz’s to continually redefine what “rhetoric” means to us (“Hebrew Bible” 134). In the past several decades, there has been increasing interest in rhetorics that challenge our preconceived notions of what constitutes “rhetoric,” both loosening the Greeks and Romans from a skewed reception history and calling for definitions of rhetoric to move “beyond the Greeks” (Lipsom and Binkley). Both these approaches highlight the need for a more diverse understanding of rhetoric—an understanding that better foregrounds the import of the Other. The still-germinal field of Jewish rhetorics has emerged as one response to these calls to diversify and decolonize the rhetorical tradition. As such, this dissertation is also a reclamation of a Jewish tradition that has been—inadvertently and explicitly—ignored, misunderstood, and suppressed.I argue that representations of divine encounters in the Tanakh (Hebrew Bible) offer a rhetorical framework for encountering the Other—human and divine—as holy. Neither appropriative nor obeisant, this framework offers a uniquely Jewish perspective on encountering the Other—one that has not received adequate academic attention. In a moment where the imperative to engage with Others is so pressing, I address that call to action by bringing together a breadth of scholarship in Jewish studies, rhetorical theory, and Biblical studies to develop a Jewish rhetorical framework for encountering the Other—human and divine—as holy, which I call a “covenant rhetoric.”This covenant rhetoric, I assert, is not reserved for encounters with the divine, but is also applicable to human rhetorical interactions. My dissertation thus offers a rhetorical model for encountering as holy the human Others with whom we share our existence. As our diverse society continues to wrestle with the ethical imperative towards the Other, I show how the Tanakh prompts us to reconsider the rhetorical potential of encountering Otherness as holiness. In the process, I demonstrate rhetoric’s centrality to religion, to spirituality, and to living an ethically-informed life.
A Systematic Framework for Analyzing the Security and Privacy of Wireless Communication Protocol Implementations
No full textWireless communication technologies, such as cellular ones, Bluetooth, and WiFi, are fundamental for today’s and tomorrow’s communication infrastructure. Networks based on those technologies are or will be increasingly deployed in many critical domains, such as critical infrastructures, smart cities, healthcare, and industrial environments. Protecting wireless networks against attacks and privacy breaches is thus critical. A fundamental step for the security and privacy of these networks is ensuring that their protocols are implemented as mandated by the standards. These protocols are however quite complex and unfortunately, the lack of secure-by-design approaches for these complex protocols often induces vulnerabilities in implementations with severe security and privacy repercussions. For these protocols, the standards are thousands of pages long, written in natural language, describe the high-level interaction of the protocol entities, and most often depend on human interpretation—which is open to misunderstanding and ambiguity. This inherently entails the question of whether these wireless protocols and their communication equipment implement the corresponding standards correctly or whether the implementations introduce vulnerabilities that can have severe consequences.In this dissertation, we systematically analyze the security and privacy of these wireless communication protocol implementations (e.g., cellular networks and Bluetooth) and develop techniques useful for both white-box and black-box analysis. For the white-box analysis, we propose a model-based testing approach–ProChecker which (1) extracts a precise semantic model as a finite state machine of the implementation by combining dynamic testing with static instrumentation, and (2) verifies the properties against the extracted model by combining a symbolic model checker and a cryptographic protocol verifier. We demonstrate the effectiveness of ProChecker by evaluating it on a closed source and two of the most popular open-source 4G LTE control plane protocol implementations with 62 properties. ProChecker unveiled 3 new protocol-specific logical attacks, 6 implementation issues, and detected 14 prior attacks. The impact of the attacks ranges from denial-of-service, broken integrity, encryption, and replay protection to privacy leakage
Exploring the Structure of Impelling Risk Factors for Sexual Aggression: Integration of Normal & Pathological Personality Traits
No full textSexual aggression occurs at alarming rates on college campuses, wherein upwards of one-third of college women report some form of sexual victimization during their college careers. While individuals of any gender may perpetrate or experience sexual aggression, this form of violence is disproportionately perpetrated by men against women. Numerous risk factors for perpetrating sexual aggression have been identified, with prominent etiological, conceptual, and explanatory models of sexual aggression all emphasizing the role of impelling risk factors—which includes dispositional or personality traits that may serve to increase proclivity to sexually aggress, as well as attitudes, beliefs, and assumptions that contribute to sexually aggressive behaviors. Despite the proliferation of research on impelling risk factors for perpetrating sexual aggression, there is little consensus on how these constructs are operationalized and to what extent similarities and dissimilarities exist between existing measures of impellance for sexual aggression. Therefore, first aim of the present study seeks to examine the underlying factor structure of impelling risk factors for sexual aggression perpetration. Importantly, personality traits may represent an important non-specific impellor for sexual aggression; yet few researchers have examined the role of normal and pathological personality traits in predicting perpetration of sexual aggression, despite the robust literature on the role of personality in predicting other forms of aggression and violence. As a result, the present study also examined the role of both normal and pathological personality traits in independently and while controlling for the effect of emergent factors of impellance in predicting sexually-aggressive outcomes. Furthermore, exploratory analyses were conducted to examine the incremental validity of emergent factors of impellance above and beyond the role normal and pathological personality traits in predicting sexually-aggressive outcomes. Participants included N = 275 men between the ages of 18 and 26 from a large public university in the midwestern region of the United States, who completed an online survey assessing impelling risk factors for sexual aggression, normal personality, pathological personality, coercive condom use resistance, sexual-intimate partner violence, sexual assault perpetration, sexual objectification, and post-refusal sexual coercion. Results from the principal component analysis suggested that a three-factor solution best explained the variance in existing measures of impellance. Results from regression analyses indicated that normal personality significantly predicted all five sexually-aggressive outcomes, and that pathological personality significantly predict four of the study’s sexually-aggressive outcomes. After controlling for the effect of impelling risk factors for sexual aggression, both normal and pathological personality traits only accounted for additional variance not explained by measures of impellance for coercive condom use resistance and sexual objectification. Broadly, results identifying the underlying factor structure of impellance align with existing theoretical models of sexual aggression; however, results from the present study also extend these models by presenting a more granular, nuanced, and differentiated view of risk factors that were previously conceptualized to perform similarly. In addition, results from the present study underscore the importance of both normal and pathological personality traits in predicting sexually-aggressive outcomes. Despite this, results from the present study also suggest that after accounting for impelling risk factors of sexual aggression, personality may only help predict minimal additional variance in sexually-aggressive outcomes. Implications for both the screening and assessment of men at risk of perpetration sexually aggression, as well as recommendations for the prevention of sexual violence are discussed
Frequency Reduction and Attenuation of the Tire Air Cavity Mode Due to a Porous Lining
No full textThe tire air cavity mode is known to be a significant source of vehicle structure-borne road noise near 200 Hz. A porous lining placed on the inner surface of a tire is an effective countermeasure to attenuate that resonance. The two noticeable effects of such a lining are the reduction in frequency and the attenuation of the air cavity mode. In this thesis, through both theoretical and numerical analysis, the mechanism of the effects of a porous lining was studied. A two-dimensional duct-shaped theoretical model and a torus-shaped numerical model were built to investigate the lined tire in conjunction with the Johnson-Champoux-Allard model describing the viscous and thermal dissipative effects of the porous material. Design parameters of the porous lining were varied to study their impact and optimal ranges of the design parameters were identified. Finally, in an experimental analysis, the sound attenuation and the frequency drop were observed in measurements of force, acceleration, and sound pressure. In conclusion, it was demonstrated that the suggested theoretical and numerical models successfully predict the effects of porous linings and that the frequency reduction results from the decreased sound speed within the tire owing to the presence of the liner
TOURISM, HOSPITALITY, EVENTS, AND LEISURE: A REDEFINITION OF AN ACADEMIC DISCIPLINE
No full textThis study seeks to address the convergence of boundaries in Tourism, Hospitality, Events, and Leisure (THEL) fields and shared objects of study. We offer a synthesized definition of THEL and discuss a set of meta-concepts that defines the core and boundaries of THEL. We argue that hospitality, experience, and place are three unifying constructs upon which all THEL scholarship activities and practice fields are established. This paper invites a system-wide conversation to stimulate prescient thinking regarding academic discipline reassessment and progress at a time when technological and societal forces are transforming work, life, and education. This research will engender new perspectives to structure research and scholarship. In the context of learning, this paper will impact the reassessment of curricular structures to provide a curriculum that is relevant and adaptive to the changing needs of contemporary society
Exploring Possible Survey Measures for Trader Harassment Intensity at Tourist Destinations
No full textThe goal of the study was to explore possible subconstructs for trader harassment intensity at destinations. To accomplish this the research team analyzed blog posts and survey data gathered through Amazon Mechanical Turk, using content and exploratory factor analyses, respectively. Five factors emerged, each with sub-constructs. They were the extent to which the visitor found their interaction with micro-trader(s) at the destination hassling, non-stop, a rip-off, threatening, and unethical. The next step is to confirm the veracity of these factors. The findings have important theoretical and practical implications. They could influence how trader harassment intensity is measured by the academy and by destination management organizations.

Quantifying the impact of airlines exit in tourism destinations. The cases of Monarch and Thomas Cook
Get PDFWe analyze the impact on tourists’ arrivals after the bankruptcies of Monarch Airlines and Thomas Cook. It draws on arrivals from the UK to Canary Islands and it employs a univariate and multivariate structural time series with level interventions. More interestingly, after Monarch exit, the policymakers applied a laissez faire strategy, which resulted in a 93.04% net loss of their level of traffic in Tenerife. However, after Thomas Cook exit, the policymakers intervened in the market proposing incentives to the incumbent airlines to cover the loss. It resulted in a 34.72% net loss of Thomas Cook level of traffic. Moreover, we provide details about the redistribution of the traffic among the incumbent airlines that diminished the net loss of passengers
PUBLIC POLICIES FOR TOURISM RECOVERY DURING COVID 19 PANDEMIC; A CASE STUDY OF SPAIN
Get PDFThe COVID-19 virus has caused the biggest worldwide economic crisis since the Great Depression of the 1930s and a “zero tourism” situation with catastrophic consequences. Many authors analyzed the economic impacts of the COVID-19 pandemic, but none of them have specifically examined Spain and government actions and public policies taken to fight the pandemic. Through the case study methodology, this paper presents a literature review of the most up-to-date studies on the impacts of the COVID-19 global pandemic. Secondly, we specify the different public intervention measures implemented by national, regional, and local authorities in Spain. Finally, we set out the different COVID-19-related public rescue strategies for the tourism and hospitality sector at the individual level, at the business level and at the destination level
On Intersections of Local Arthur Packets for Classical Groups
No full textIn this thesis, for symplectic and split odd special orthogonal groups over a p-adic field, we provide an extensive account of the intersection of local Arthur packets. More specifically, following Atobe’s reformulation of Mœglin’s construction of local Arthur packets, we give precise algorithms to determine whether a given representation lies in any local Arthur packet. Furthermore, if the representation does lie in a local Arthur packet, we give a systematic approach to determine all the other local Arthur packets which also contain the representation. These algorithms are based on certain operators which act on certain construction data coming from Atobe’s parametrization of the local Arthur packets
