Abstract
A linear programming method has been used to design antenna array patterns that suppress interference from certain directions. The method is particularly useful since any degree of suppression can be specified. It is not necessary to impose exact nulls onto the pattern, although this can be done if desired. Moreover, by constraining real excitations to lie in the interval [‐1, 1], a pattern is obtained in which the majority of excitations remain at the quiescent value of unity. The method can be modified in principle to incorporate any other appropriate linear equality or inequality constraints on the pattern or the excitations. A detailed description of the method is given and several illustrative examples are included.

Abstract
Purpose: This study examines the experiences and struggles of young women with breast cancer as they navigate the intersectionality of their illness and gender identity. Specifically, the research explores the construction and expression of gender identity as a core part of who they were prior to diagnosis and who they desire to be in the future.
Design and methodology: A phenomenological approach was used to investigate how women with breast cancer experience changes related to gender identity. Eighteen in-depth interviews were conducted with young women who have been diagnosed within the last five years.
Findings: Young women undergo gender identity disruptions and shifts as the result of breast cancer diagnosis and treatment. Informants expressed feelings that their resultant identities do not conform to cultural normative representations of gender, which profoundly impact their perceptions of the physical self, gender roles, and intimate relationships. At this acute stage, they struggled with the loss of important body markers of femininity (breasts, hair, etc.) and attempted through consumption to find alternative ways to enact gender expressions.
Originality and value: This research explores consumer experiences when bodies do not conform to idealized body images and cultural representations of gender. Informants revealed a complex portrait of women who experience the early, invasive stages of illness and body transformation.

Abstract
Purpose
This conceptual chapter explores the role of embodiment in phenomenological experience of lived time, and the implications it may hold for studying consumption.
Methodology/approach
Conceptual chapter.
Findings
We argue that though consumer research scholars have become increasingly cognizant of the embodied foundation of temporal experience, the relation between embodied experience of time and consumption activity still remains under-theorized and researched. Through a phenomenological perspective we are able to understand the consumer as temporally directed toward the world where value is realized emergently through embodiment of affordances.
Originality/value of chapter
We build an existing work in consumer research to open up a possibility for a phenomenological experience of consumption that is, to a great extent, precognitive, temporal, and based on the ability to experience lived time.

Abstract
Although stress has become a prominent research theme in consumer behavior and occupational health, to the authors knowledge there is only one review on the relationship between consumer behavior and stress (i.e., when internal and external factors exceed an individual’s resources and endangering the individual’s well-being) and this was published 10 years ago. Further, research on occupational stress has yet to be fully integrated into the consumer stress literature. In this chapter, the authors attempt to advance research on consumer stress by a drawing on a satisfaction mirror framework which outlines that consumers and employees influence each other through a “mirror” where they positively and cyclically influence each other in a service environment. The authors argue that consumers and employees may likewise mirror each other in a negative cycle of stress and well-being depletion. First, the authors describe how stress is viewed in consumer behavior and marketing. Second, the authors review evidence that consumption serves as a form of coping with stress. Third, the authors discuss the role of consumption as a stressor that may drive consumer stress. Finally, the authors introduce the satisfaction mirror model and outline the bi-directional influence on increased stress and well-being depletion at the consumer–employee interface in service encounters. The model introduced in this chapter serves as a framework for organizing findings related to stress and well-being in the fields of consumer behavior and occupational health. In addition, the model serves as a springboard for developing propositions for future research. Ultimately, the authors hope this chapter both updates and builds upon previous findings on stress and consumer behavior, as well as grounds future research on stress and well-being at the intersection of consumers and employees.

Abstract
During the latter half of the 20th century many states began to use the lottery as an alternative method to increasing the amount of revenue within their general funds. Apparently, this method was a lot more palatable than increasing taxes. Passing lottery legislation was easier in states where the funds were partially or wholly designated for primary, secondary, or higher education. The main purpose of this paper is to determine if the presence of a lottery impacts educational outcomes (high school graduations rates, bachelor degrees awarded, ACT, and SAT scores). Using state level data for the period 1985-2000 in a pooled time series regression model, the analysis indicates that the presence of a lottery is useful in models explaining educational outcomes.

Abstract
Purpose
The purpose of this chapter is to provide a comprehensive analysis of how sentiments may be a part of, or adjacent to, status generalization. We demonstrate why this problem is so difficult to solve definitively, as many resolutions may exist. Sentiments may present the properties of graded status characteristics but may also be disrupted by processes of the self. Sentiments may have status properties enacted within dyadic interactions. However, sentiments may also be status elements during triadic constellations of actors. Finally, we discuss current research that is underway to provide more empirical evidence to offer confirmation or disconfirmation for some of our proposed models.
Methodology/Approach
We provide a synthesis of literatures, including pieces from group processes, neuroscience, psychology, and network scholarship, to address the relation between sentiment and status processes. Accordingly, this is a conceptual chapter.
Research Limitations/Implications
We attempt to motivate future research by exploring the many complications of examining these issues.
Social Implications
Understanding how social inequalities may emerge during group interaction allows researchers to address their deleterious effects. Positive sentiments (in other words, “liking”) should bring actors closer together to complete tasks successfully. Ironically, when paired with negative sentiments within task groups, inequalities in group opportunities may result. To address these social inequalities, a thorough understanding of how they develop is necessary, so that efficacious interventions can be adopted.
Originality/Value
This deep dive into the relation between sentiment and status processes joins the 25-year quest to understand the issues surrounding this relationship.

Abstract
Purpose
The purpose of this paper is to design, investigate and optimize a horizontal axis tidal turbine (HATT) using computer-aided numerical simulation and computational fluid dynamics (CFD). This is the first step of research and development (R&D) for implementation in the Persian Gulf condition. To do so, suitable locations are reviewed. Then, the optimization is focused on determining the optimum fixed pitch angle (β) of a three-bladed HATT based on the widespread multiple reference frame (MRF) technique to calculate power and thrust coefficients at different operational rotating speeds.
Design/methodology/approach
To simplify the problem and reducing the computational costs due to cyclic symmetry only one blade, accordingly one-third of the whole computational domain is considered in the modeling. Due to flow’s nature involving rotating, separation and recirculation, a realizable κ-ε turbulence model with standard wall function is selected to capture flow characteristics influenced by the rotor and near the wall region. Simulations are conducted for two free-stream velocities, then compared with their dependencies through the dimensionless tip speed ratio (TSR) parameter.
Findings
The validation process of the simulations is carried out by the use of AeroDyn BEM code, which has been evaluated by comparing with two experimental data. As results, the highest coefficient of power is achieved at ß = 19.3° at TSR = 4 with the value around 0.41 and 0.816 for thrust coefficient. Furthermore, to comprehend the rotor’s performance and simulation method, flow characteristics due to the rise in angular velocity is discussed in detail. Moreover, the major phenomenon, cavitation occurrence, is also checked at the critical situation where it is found to be safe.
Originality/value
By comparing and evaluating the results to other HATTs, it implies that the proposed rotor of this study is feasible and proved by CFD evaluation at this step. However, the current rotor is awaiting a justification through experimental assessment.

Abstract
Purpose
To explain how reading, rewinding a story in reverse order, and then rereading allows a reader to contextualize information, acquiring not only major themes and events but also details and other literacy characteristics of the literature selection.
Design/methodology/approach
A representation of sequencing structures is discussed including world-related, concept-related, inquiry-related, learning-related, and utilization-related. In addition, the instructional design aspects of backwards sequencing are discussed.
Findings
Just as a level or stud finder uses a back-and-forth approach for finding the most suitable position, so does the backwards sequential approach to reading comprehension. By slowing down and focusing on parts before the whole, students are more likely comprehend content.
Practical implications
The importance of prediction towards comprehension has been recognized for decades. However, using a learning design that features reading a story once, then revisiting the story structure components in backwards order, and finally reading it again, allows for precise and complete learning. This theory has research and pedagogical implications for students of all ages.

Abstract
The world revolves around sound. Children who are deaf/hard of hearing (D/HH) lack access to sound, thus need careful monitoring and planning to ensure they have access to adequate language models and supports to develop a strong language foundation. It is this foundation that is needed to ensure D/HH children are able to achieve developmental and academic milestones. Research is emerging to suggest specific intervention strategies that can be used to support D/HH children from birth throughout their educational career. In this chapter, we highlight several strategies that can be used to support communication, language, academic, and social/emotional growth. We freely admit that this is in no way a comprehensive and exhaustive list, but rather only scratches the surface. The field of deaf education and related research and technology is constantly changing. To ensure adequate educational access, it is highly recommended that a professional specialized in hearing loss be a part of the educational team any time a child is identified as having any degree or type of hearing loss.
