Abstract:
This sermon, on Matt 17:1–9, reflects on the aftermath of the 2016 United States election, asking the question of whether or not we, as Christians, will be overcome by fear or by faith. Using the example of Dietrich Bonhoeffer, this sermon argues that we should become what Bonhoeffer in his life’s work tried to create: a radical community of Christ that does not allow itself to be overcome either by the fear of the Other, which demagogues among us will always seek to exploit on their path to power, or by the very real fears associated with authentic gospel living, but which instead allow faith to power its every decision.

Abstract:
Fears and anxieties are part of the normal development of a child, and, as a rule, developmental fears and anxieties are transient. However, for some children, dental fears and anxieties persist and become persistent and problematic. Many different mechanisms have been proposed to explain the development of CVD in children; however, there is general agreement that the aetiology of childhood CVD is multifactorial. Endogenous sources of CVD are internal factors that make people susceptible to the development of dental anxiety. It is important to understand that the influence of close family members can help or hinder treatment. Endogenous factors that can increase a person's susceptibility to CVD include genetic vulnerability, personality traits, age and gender. A high level of CVD among young people is associated with social, emotional and behavioural problems, general anxiety and the temperamental trait of negative emotionality. Having fears and anxieties is considered part of a child's normal development and follows a consistent and predictable pattern of adult life. Poor communication between the dentist and the patient not only contributes to the development of CVD but plays an important role in maintaining dental anxiety. Therefore, all members of the dental staff must be aware of how their behaviour can affect children.

Abstract:
Normal brain functioning relies critically on the ability to control appropriate behavioral responses to fearful stimuli. Overgeneralized fear is the major symptom of anxiety disorders including posttraumatic stress disorder. This review describes recent data demonstrating that the medial prefrontal cortex (mPFC) plays a critical role in the refining of cues that drive the acquisition of fear response. Recent studies on molecular mechanisms that underlie the role of mPFC in fear discrimination learning are discussed. These studies suggest that prefrontal N-methyl-D-aspartate receptors expressed in excitatory neurons govern fear discrimination learning via a mechanism involving cAMP response element-binding protein-dependent engagement of acetyltransferase.

Abstract:
Escape maintained behavior in dogs is generally displayed by one of two behaviors-fleeing or aggression. Once aggression is negatively reinforced by the removal of the aversive stimulus, it is very difficult to eliminate from the organism's repertoire. Counterconditioning is the process of pairing a positive reinforcer with an aversive stimulus in the attempts that an organism will no longer exhibit fear responses in its presence. This process must be done gradually with small approximations. Many organisms have been trained to tolerate the presence of aversive stimuli via counterconditioning. However, this process can be time consuming and has inconsistent results. The purpose of this experiment was to monitor the effects of counter conditioning around an aversive stimulus while simultaneously training an identical behavior in the presence of a neutral stimulus. The results demonstrated that even though counterconditioning produced approach to the aversive stimulus the subject still exhibited numerous fear responses when results were compared to the control condition.

Villanueva, Karen Nelson. "Invoking the blessings of the Tibetan Buddhist Goddess Tara through chanting her mantra to overcome fear." Thesis, California Institute of Integral Studies, 2014. http://pqdtopen.proquest.com/#viewpdf?dispub=3606937.

Full text
Abstract:

In Tibetan Buddhism, the Goddess Tara represents the feminine nature of the divine. She is a popular Tibetan deity who has been embraced by many Western feminists because she is said to have rejected the belief extolling that one could not become enlightened in a female body. Vowing to always be reborn as a woman until she attained enlightenment as a Buddha, she is reputed to come swiftly and compassionately to our aid when called upon. She may be invoked through prayer, visualization, and mantra, of which there are several specifically ascribed to her many forms of manifestation.

Fear can cause suffering that may be an obstacle to achieving higher realizations that lead to enlightenment. As a meditational deity, Tara is especially efficacious in saving us from our fears. This dissertation explores the experience of contemporary Western people who invoked the blessings of the Goddess Tara through chanting her mantra to overcome a stated fear. Using a participatory research methodological approach, twelve coparticipants met at an urban Buddhist center on six occasions in order to meditate and chant Tara’s mantra together. Over the three months of the study, the coparticipants created small home altars, attempted to chant alone, and journaled about the overall experience.

An examination of their fears (e.g., fear of having children, fear of failure, fear of expressing the self, fear of ending a relationship, fear of sexuality, and a fear of being open, etc.) revealed that many coparticipants exhibited a fear of love or connection to love. During this study, an exploration of their journals revealed that all of the coparticipants experienced a lessening of fear. According to Buddhist beliefs, chanting Tara’s mantra supports the realization of love, like that first experienced with one’s mother, and this, in turn, may develop one’s compassion for all beings. This notion was supported by the experience of several coparticipants who commented on how Tara was manifesting in their lives and who began to recognize her presence. Ultimately, their experience was consistent with Buddhist beliefs in the efficacy of using mantra.

Full text
Abstract:
Gibbons (2015) writes that speaking is considered as the most important skill in language learning. However, Lundahl (2014) states that there are some pupils, in year 4-6, in Sweden who do not speak during the English lessons. Thus, the aim of this study is to find out what the reasons behind EFL pupils' unwillingness to speak English are. Furthermore, teaching strategies to overcome pupils' speaking anxiety are investigated. There are many studies that investigate the underlying reasons. The data collection, for this thesis, consists of interviews with some student-teachers at Malmö University. The results showed that traditional teaching methods along with fear of making linguistic errors are two of the main reasons. In addition, negative evaluation from peers and fear of producing grammatically incorrect sentences are also factors that contribute to some pupils’ anxiety over speaking English. According to our interviewees, the implementation of a safe, supportive and communicative environment in the classroom is crucial for encouraging and motivating pupils in language learning. Providing different authentic communicative tasks, songs, stories, and games that are related to pupils' lives and interests, as well as their needs and knowledge levels, are some of the strategies employed by some teachers.

Few studies in past leisure literatures have emphasized on individual’s autonomy from the perspective of leisure constraints. Based on this deficiency, the major purpose of this study was trying to examine the possibility of overcoming personal leisure constraints by utilizing the theory and six cases who experienced drowning, for the purpose of demonstrating the process of personal agency in making leisure choices. A qualitative research has been employed in this study, and six 60-80 minutes in-depth interviewees were used for qualitative data collection. Through the procedure of narrative analysis and grounded theory, including the data transcribing and deductive analysis, the following theories were acquired: (1) The drowning experience had positive contribution to a participant’s (in aquatic sports) self-recognition regarding his/her capability in doing aquatic sports; (2) Self-efficacy played a significant role in the process of overcoming personal constraints; (3) The occurrence of flow experience was somehow possible for those participants who had drowning experience before. Helpfully, those insightful findings provided a profound ground to enrich the traditional recognition toward the theory of leisure constraints.

Abstract:
This chapter explores the impact of political violence on children and youth through an examination of theory and research, particularly social-ecological systems theory, dealing with prolonged exposure to armed political conflicts and experiences of single-incident attacks. The chapter discusses both the direct traumatic effects of being a victim of political violence and the indirect effects of living in communities and societies in which the experience of violence is transmitted through the media to the minds of children, adults, and policymakers. The chapter further discusses the role and limitations of psychological resiliency and the importance of fostering normalcy to help children overcome the effects of exposure to political violence. The chapter concludes with suggestions for programmatic initiatives at the community and national level that reinforce a return to normalcy and provide assistance to traumatized children and adolescents.

Abstract:
When our patients are diagnosed with fibromyalgia, their initial reaction generally is “What?” At this point, we provide them with literature from fibromyalgia support groups and the Arthritis Foundation and explain what this condition means. Often we meet with family members to reinforce the educational process. In mild cases, this creates a sense of relief. Some patients who have seen several physicians and been given various diagnoses have differing reactions: “Are you just trying to put me off?” “My last rheumatologist said the same thing, told me he could do nothing for it, and sent me back to my family doctor.” “Are you sure it’s not lupus or Lyme disease or cancer?” Once our patients have accepted the diagnosis and read about the syndrome, we examine their behavior patterns and try to find ways to help them deal with the diagnosis in a constructive manner. This chapter reviews some of the emotional reactions our patients display and problems they have to deal with, gives practical advice on how to surmount obstacles, and describes community resources that help patients overcome the syndrome. It’s hard enough to get through the day when feeling unwell. In fibromyalgia, the sense of being unwell is manifested by fatigue, pain, spasm, poor sleeping, lack of stamina or endurance, and sometimes difficulty concentrating or focusing. Fibromyalgia patients frequently react to these sensations with specific attitudes, emotions, and other behavioral responses, including anxiety, anger, guilt, loss of self-esteem, depression, and fear. There are no physical markers of fibromyalgia that reveal the syndrome to others. Fibromyalgia patients have no deformities, don’t have an X marked on their fore head, look healthy, and seem able to be active. While this is good for the patient in one sense, friends, employers, and loved ones often have difficulty believing that they have so many complaints. Therefore, it’s important to be open and frank with those who care. You need to have their trust to help them understand the limitations imposed by fibromyalgia. Patients do not need to be coddled or treated like invalids; they crave and need understanding and respect.

Abstract:
In political rhetoric, academic analysis, social theory and everyday speech, fear is characterised as a limitation or an obstacle to be overcome – see turns of phrase such as ‘culture of fear,’ ‘management by fear’ and so on. This introduction argues for a more useful conception of fear, based on Ernst Bloch’s continuum of ‘negative expectant emotions,’ and combines this with a Sartrean conception of the absurdity of human existence to establish the function of monsters in human culture. In short, monsters reveal the limitations of our ideologically constructed world by breaking it: history cannot continue in their presence; they refute humanity’s ownership of the world, and traditionally, they have occupied spaces where human civilization cannot or will not go. Each monster disrupts history in a way particular to itself, and this chapter lays the groundwork for further analysis along those lines.

Abstract:
This chapter identifies the possible barriers to deprescribing, and presents suggestions for strategies to overcome them. Although deprescribing has the potential to streamline medication regimens, minimize side effects, cut costs, improve patient adherence, and strengthen the relationship between the patient and the prescribing professional, barriers may originate from the patient, physician, and/or the institution, both local and the larger medical institution. Barriers related to prescriber-related factors such as the physician’s illusion and fear of litigation, are discussed. Potential patient- and environment-related barriers are also discussed, including sociocultural factors which may emerge in the process of initiating a course of deprescribing. Included in this chapter is a discussion of the possibility of relapse, colloquially defined, and the patient’s and provider’s fears for rehospitalization. Possible strategies for overcoming each of these barriers are discussed.

Abstract:
Music composition is embedded into the Viterbo University music theory curriculum to promote active engagement of musical materials. The project accomplishes three basic complementary outcomes: 1) Students will be able to creatively apply and develop the foundations of music theory learned in their first year of university-level music study, 2) Students will develop proficiency using music writing software, and 3) Students will overcome their fear of composition and gain confidence as musicians. Students are taught foundational concepts during the first four semesters of music theory; these concepts are creatively applied and developed in the gestation and birth of a musical composition that is original and personal. Meaning and purpose, combined with guidance and encouragement, sustain these freshmen and sophomore students over a five-month process of framing a concept, composing music, editing their scores, and finally rehearsing and performing their works. The “concept” for the 2018-2019 freshmen and sophomore music theory students was a collaborative venture with Gateway Christian School, which is part of Project Gateway in Pietermaritzburg, South Africa. Poetry written specifically for this project by Grade 7 students was collected and given to Viterbo University students for setting; the learning outcomes, as well as the benefits and global focus of the project will be the focus of this paper.

Abstract:
Personalized and timely feedback has the potential to improve an individual’s performance on a wide variety of engineering tasks. The ability to capture an individual’s affective state(s) and performance on a task is a key component needed to advance personalization of feedback. While automated methods exist for quantifying task performance, the ability to quantify an individual’s affective state(s) remains an open research area. Existing methods for quantifying an individual’s affective state(s) are challenging to implement where real-time assessment is needed (e.g., engineering workshop environments). This has sparked a growing interest for automated systems capable of inferring individuals’ affective state(s), based on their projected facial or body cues. However, existing methods attempt to employ a general model to label an individual’s affective state(s) into discrete categories, such as fear, joy, surprise, etc. Nonetheless, emotional expressions are far more complex, as individual differences in facial expressions, may deteriorate the performance of these systems in providing personalized feedback. To overcome these limitations, this work proposes a machine learning method for predicting an individual’s performance on a task by utilizing his/her unique facial keypoint data, hereby bypassing the need to infer his/her discrete affective states. A case study involving 31 participants is presented. The support vector machine model employed to predict an individual’s performance yielded an accuracy of 77.15% for an individual-task specific model. In contrast, a general model yielded an accuracy of only 52.69%, hereby supporting the authors’ argument that individual-task specific models are more suitable for advancing personalized feedback.

Abstract:
The outbreak of COVID-19 pandemic was a shock for the global economy. It affected almost every country, but certainly in developing countries its impact was harder. The immediate effect was the shortage of several medical and paramedical equipment which were necessary to prevent the virus spread. This shortage was felt in Albanian markets as well and was rapidly followed by a sharp increase of prices in paramedical products. The consumers suffered the highly increased prices amongst fear that in absence of these products, their life was threatened. This behaviour of the market participants was considered suspicious by the Competition Authority which decided to initiate a preliminary investigation to find out whether this behaviour was abusive, or it normally reflected the sudden shortage and the state of emergency. The instigation of this procedure was based on several complaints reported in the media and complaints directly submitted by consumers to the Competition Authority. At the first glance, the traders were exploiting the health emergency to maximise their profits. Subsequently, the Competition Authority (CA) decided to apply some preliminary measures on the wholesale market operators. Furthermore, the CA intervened even in a case of a company in dominant position which was furnishing selected pharmacies. These interventions aimed at restoring somehow the distorted competition in paramedical and medical products. This article will try to shed light on the current market situation and on the effectiveness of the interventions of the CA. How should the Competition Authority behave to restore the distorted competition? Are the current introduced measures enough to help all market participants overcome this state of health emergency? These questions and other issues related with the peculiar situation will be addressed in the current article. The article will be organized as follows: First, a glimpse of the regulation of Albanian competition law will be given. Second, the situation under COVID-19 emergency will be elaborated taking into consideration the guidelines of Communication of the Commission on “Temporary Framework for assessing antitrust issues related to business cooperation in response to situations of urgency stemming from the current COVID-19 outbreak” (2020/C 116 I/02). Lastly, the evaluation of the measures introduced by the Competition authority will be analysed and recommendations will be provided.

Abstract:
Designers need a way to overcome information related risks, including information leakage and misuse from their own collaborators during a collaborative product realization process. Existing cryptographic techniques aimed at overcoming these information related risks are computationally expensive and slow even for moderate problem sizes, and legal approaches (e.g., the use of non-disclosure agreements) are not effective. The computational practicality problem is particularly pronounced for simulation computations like finite element analysis (FEA), that involve both a geometric partitioning (meshing) and computations of cubic time complexity. In this paper, we propose a technological approach that enables designers to perform simulations, such as FEA computations, without the need for revealing their information to anyone, including their design collaborators. We demonstrate our approach using secure finite element analysis (sFEA) which enables designers to perform FEA without having to reveal structural/material information to their counterparts even though the computed answer depends on all the collaborators’ confidential information. We build sFEA using computationally efficient protocols implementing a secure co-design framework. One of our findings is that the most natural implementations of sFEA, using existing protocols, suffer from limited scalability. To overcome these limitations, we propose strategies that help improve the scalability of sFEA. We document and discuss the experiments we conducted to determine the computational overhead imposed by sFEA. The results indicate that the computational burden imposed by sFEA makes it challenging for large-scale FEA — our scheme significantly increases the problem sizes that can be handled when compared to implementations using previous algorithms and protocols, but large enough problem sizes will swamp our scheme as well (in some sense this is unavoidable because of the cubic nature of the FEA time complexity). This work is another step towards opening up new avenues for improving the way information is exchanged in collaborative simulation computations such as FEA.

Abstract:
Thermal analysis of a turbine disc through a transient test cycle is demonstrated using 3D computational fluid dynamics (CFD) modeling for the cooling flow and 3D finite element analysis (FEA) for the disc. The test case is a 3D angular sector of the high pressure (HP) turbine assembly of a civil jet engine and includes details of the coolant flow around the blade roots. Proprietary FEA and CFD solvers are used to simulate the metal and fluid domains, respectively. Coupling is achieved through an iterative loop with smooth exchange of information between the FEA and CFD simulations at each time step, ensuring consistency of temperature and heat flux on the coupled interfaces between the metal and fluid domains. The coupled simulation can be completed within a few weeks using a PC cluster with multiple parallel CFD executions. The FEA/CFD coupled result agrees well with corresponding rig test data and the baseline 3D and 2D FEA solutions, which have been calibrated using test data. Provision of upstream boundary conditions and modeling of rapid transients are identified as areas of uncertainty. Averaging of CFD solutions and relaxation is used to overcome difficulties caused by CFD oscillations associated with flow unsteadiness. The present work supports the continued use and development of the FEA/CFD coupling method for industrial applications.

Abstract:
The electrosurgical sealing method has risen to prominence in recent years as more vessel sealing procedures are being conducted in minimally invasive surgery. Electrosurgical sealing works by applying electrical current to coagulate and denature proteins in the vessel, thereby creating a bond. In this study, experiments were conducted to seal 3 and 8 mm diameter vessels in a porcine model with a bipolar electrosurgical device and measure the electrical voltage and current, and temperature distribution in the vessel near the area of the seal. The vessel seal was modeled with finite element analysis (FEA) and compared to the experimental data. FEA allow for insight into the correlation of temperature to quality of the seal in the vessel. The maximum temperatures were 83°C and 63°C in the 3 and 8 mm vessels, respectively. Validation of the experimental results was attempted through the use of a simplified FEA model. The model showed similar thermal profiles near the electrode, but further downstream temperatures did not rise as fast as the experimental results. Further refinement to overcome limitations in the model is identified.

Abstract:
To adapt the miniaturized development tendency of nanometer positioning devices, a new type of micro-displacement stage with six degree of freedom, which can implement nanometer-level ultra-precision positioning without feedback control is designed. It takes a group of piezoelectric ceramics actuators (PZTAs) connected in series as actuation unit, takes flexure hinges as elastic guide rail. To overcome the non-linearity and hysteresis of PZTAs, binary actuation principle is adopted to control a group of actuators that work together to output many discrete, repeatable displacements. If these displacements are distributed within a scope of several microns, only simple on and off actuator commands may obtain nanometer-level repeatable positioning without feedback control. Theoretical calculation and finite element analysis (FEA) are used to design and simulate the stage. Expressions of rigidity and stress are obtained by theoretical calculation. FEA and experimental results verify the rationality and feasibility of the stage.

Abstract:
Closure bolt loads in a flanged cylindrical containment vessel under internal pressure are determined by detailed Finite Element Analysis (FEA) and compared to values determined using NUREG/CR-6007 equations. The containment vessel is of small diameter with an inwardly dished bolted head that geometrically contrasts with the large, flat lidded casks which the NUREG addressed. The comparison showed a significant difference in the magnitude of pressure driven prying load between the FEA model and the NUREG approximate equations. This difference affected the predicted pressure that overcomes preload, and the rate of load increase after preload was exceeded. The difference was likely due to the contrasts between this vessel’s closure shape compared to the more typical flat cask lid shape used in the NUREG development.
