Consumption as Emotion Regulation

Products and services often provide value that goes beyond functional utility. Drawing from a compensatory consumption model, which suggests that consumption is a means to regulate self-discrepancies, the current research suggests that consumers are motivated to self-regulate their emotions and this self-regulation can be accomplished via consumption. Specifically, emotional and physiological deviations from a steady state motivate individuals to find balance in order to alleviate those deviations. Three papers provide evidence for this hypothesis. Utilizing an embodied cognition framework for chapter 2 and chapter 3, I demonstrate that individuals are motivated to reduce a perceived lack of interpersonal warmth by substituting physical warmth, and vice versa (chapter 2). Next, I argue that experiencing action regret results in self-conscious emotions (e.g. shame, guilt) associated with physical warmth, which in turn motivates individuals to ameliorate those emotional states via interaction with objects that are perceived to be physically or psychologically opposite in temperature (chapter 3). Finally, in chapter 4, I argue that sadness can serve as a regulatory mechanism to alleviate loneliness and achieve social connectedness

Exactness of the Original Grover Search Algorithm

It is well-known that when searching one out of four, the original Grover's search algorithm is exact; that is, it succeeds with certainty. It is natural to ask the inverse question: If we are not searching one out of four, is Grover's algorithm definitely not exact? In this article we give a complete answer to this question through some rationality results of trigonometric functions.Comment: 8 pages, 2 figure

Perceiving the agency of harmful agents: A test of dehumanization versus moral typecasting accounts

It is clear that harmful agents are targets of severe condemnation, but it is much less clear how perceivers conceptualize the agency of harmful agents. The current studies tested two competing predictions made by moral typecasting theory and the dehumanization literature. Across six studies, harmful agents were perceived to possess less agency than neutral (non-offending) and benevolent agents, consistent with a dehumanization perspective but inconsistent with the assumptions of moral typecasting theory. This was observed for human targets (Studies 1–2b and 4–5) and corporations (Study 3), and across various gradations of harmfulness (Studies 3 and 4). Importantly, denial of agency to harmful agents occurred even when controlling for perceptions of the agent’s likeability (Studies 2a and 2b) and while using two different operationalizations of agency (Study 2a). Study 5 showed that harmful agents are denied agency primarily through an inferential process, and less through motivations to see the agent punished. Across all six studies, harmful agents were deemed less worthy of moral standing as a consequence of their harmful conduct and this reduction in moral standing was mediated through reductions in agency. Our findings clarify a current tension in the moral cognition literature, which have direct implications for the moral typecasting framework

Bound on the multiplicity of almost complete intersections

Let $R$ be a polynomial ring over a field of characteristic zero and let $I \subset R$ be a graded ideal of height $N$ which is minimally generated by $N+1$ homogeneous polynomials. If $I=(f_1,...,f_{N+1})$ where $f_i$ has degree $d_i$ and $(f_1,...,f_N)$ has height $N$, then the multiplicity of $R/I$ is bounded above by $\prod_{i=1}^N d_i - \max\{1, \sum_{i=1}^N (d_i-1) - (d_{N+1}-1) \}$.Comment: 7 pages; to appear in Communications in Algebr

Lie, Cheat, and Steal: How Harmful Brands Motivate Consumers to Act Unethically

While brand punishment—through either individual or collective action—has received ample attention by consumer psychologists, absent from this literature is that such punishment can take the form of unethical actions that can occur even when the consumer is not personally harmed. Across three studies, we examine consumers’ propensity to act unethically towards a brand that they perceive to be harmful. We document that when consumers come to see brands as harmful—even in the absence of a direct, personal transgression—they can be motivated to seek retribution in the form of unethical intentions and behaviors. That is, consumers are more likely to lie, cheat, or steal to punish a harmful brand. Drawing on these findings, we advance implications for consumer psychologists and marketing practitioners and provide avenues for future research in the area

Central band interosseus membrane reconstruction for longitudinal instability injuries of the forearm

Aims Acute and chronic injuries of the interosseus membrane can result in longitudinal instability of the forearm. Reconstruction of the central band of the interosseus membrane can help to restore biomechanical stability. Different methods have been used to reconstruct the central band, including tendon grafts, bone-ligament-bone grafts, and synthetic grafts. This Idea, Development, Exploration, Assessment, and Long-term (IDEAL) phase 1 study aims to review the clinical results of reconstruction using a synthetic braided cross-linked graft secured at either end with an Endobutton to restore the force balance between the bones of the forearm. Methods An independent retrospective review was conducted of a consecutive series of 21 patients with longitudinal instability injuries treated with anatomical central band reconstruction between February 2011 and July 2019. Patients with less than 12 months’ follow-up or who were treated acutely were excluded, leaving 18 patients in total. Preoperative clinical and radiological assessments were compared with prospectively gathered data using range of motion and the abbreviated version of the Disabilities of the Arm, Shoulder and Hand questionnaire (QuickDASH) functional outcome score. Results Of the 18 patients (nine male, nine female) who met the inclusion criteria, the median follow-up was 8.5 years (interquartile range (IQR) 5.6 to 10). Their mean age was 49 years (SD 11). The mean extension improved significantly from 38° (SD 15°) to 24° (SD 9°) (p = 0.027), with a mean flexion-extension arc change from 81° (SD 27°) to 93° (SD 30°) (p = 0.172) but with no forearm rotational improvement (p = 0.233) at latest follow-up. The QuickDASH functional score improved significantly from 80 (SD 14) to 52 (SD 26) following reconstruction (p = 0.031), but generally the level of disability remains high. Radiological assessment showed no progression of proximal migration of the radius, with a stable interbutton distance and ulnar variance from immediate postoperative radiograph to the latest follow-up. Conclusion Central band interosseus membrane reconstruction using a synthetic braided cross-linked graft can improve patient-rated arm function and range of motion, but significant functional deficits remain in patients with chronic injuries.</p

Greenwashing No More: The Case for Stronger Regulation of Environmental Marketing

Fraudulent and deceptive environmental claims in marketing (sometimes called “greenwashing”) are a persistent problem in the United States, despite nearly thirty years of efforts by the Federal Trade Commission (FTC) to prevent it. This Essay focuses on a recent trend in greenwashing - fraudulent “organic” claims for nonagricultural products, such as home goods and personal care products. We offer three recommendations. First, we suggest ways that the FTC can strengthen its oversight of “organic” claims for nonagricultural products and improve coordination with the USDA. Second, we argue for inclusion of guidelines for “organic” claims in the next revision of the FTC’s Guidelines for the Use of Environmental Marketing Claims (often referred to as the “Green Guides”), which the FTC is scheduled to revise in 2022. Finally, we assert that the FTC should formalize the Green Guides as binding regulations, rather than their current form as nonbinding interpretive guidance, as the USDA has done for the National Organic Program (NOP) regulations. This Essay concludes that more robust regulatory oversight of “organic” claims, together with efforts by the FTC to prevent other forms of greenwashing, will ultimately bolster demand for sustainable products and incentivize manufacturers to innovate to meet this demand

Earth Systems Science and Engineering

Providing the essential energy and water systems to support human needs while understanding and addressing their environmental consequences is a watershed problem for the 21st century. The LLNL Earth System Science and Engineering Program seeks to provide the scientific understanding and technological expertise to help provide solutions at both global and regional scales. Our work is highly collaborative with universities, laboratories and industrial partners across the world and involves observational data, laboratory experiments, and numerical simulations. The energy systems we have enjoyed for the last 100 years have resulted in the advanced standard of living in the developed world and a major emerging problem with climate change. Now we face a simultaneous realization that our reliance on fossil fuels is a source of conflict and economic disruption as well as causing potentially abrupt, even catastrophic global climate change. The climate and energy problem is perhaps the greatest challenge ever faced by mankind. Fossil fuel remains the least expensive and most available source of energy and the basis of our economy. The use of fossil fuels, especially over the last 100 years has led to a 30% increase in CO{sub 2} in the atmosphere. The problem is growing. The population of the Earth will increase by several billion people in the next 50 years. If economic growth is to continue, the demand for energy is estimated to approximately double in the next 50 years so that we will need approximately 10 TW more energy than the 15 TW we use now. Much of this demand will come from the developing world where most of the population growth will occur and where advanced energy technology is not generally used. The problem affects and is affected by a complex system of systems. The climate and energy problem will affect resources, social structure and the probability of increased conflict. No one person, no one nation, no one technology can solve the problem. There is no parallel precedent on which to model a solution. On these grounds, we have chosen to tackle four key tasks: (1) Understanding the natural Earth system and anthropogenic systems examining key forcings and processes driving these systems and the interactions between systems; (2) Identify climate change impacts important to society and develop strategies and technologies to adapt to the climate change that is inevitable given past, current, and potential emissions; (3) Developing strategies and technologies to reduce/eliminate greenhouse gas emissions thereby mitigating climate change while generating energy that is economically and socially viable; and (4) Engaging with appropriate economic, legal, social, and political structures to inform key decisions

On Dijkgraaf-Witten Type Invariants

We explicitly construct a series of lattice models based upon the gauge group $Z_{p}$ which have the property of subdivision invariance, when the coupling parameter is quantized and the field configurations are restricted to satisfy a type of mod-$p$ flatness condition. The simplest model of this type yields the Dijkgraaf-Witten invariant of a $3$-manifold and is based upon a single link, or $1$-simplex, field. Depending upon the manifold's dimension, other models may have more than one species of field variable, and these may be based on higher dimensional simplices.Comment: 18 page

Design of Matched Zero-Index Metamaterials Using Non-Magnetic Inclusions in Epsilon-Near-Zero (ENZ) Media

In this work, we study the electrodynamics of metamaterials that consist of resonant non-magnetic inclusions embedded in an epsilon-near-zero (ENZ) host medium. It is shown that the inclusions can be designed in such a way that both the effective permittivity and permeability of the composite structure are simultaneously zero. Two different metamaterial configurations are studied and analyzed in detail. For a particular class of problems, it is analytically proven that such matched zero-index metamaterials may help improving the transmission through a waveguide bend, and that the scattering parameters may be completely independent of the specific arrangement of the inclusions and of the granularity of the crystal. The proposed concepts are numerically demonstrated at microwaves with a metamaterial realization based on an artificial plasma.Comment: 38 pages, 10 Figures, under revie
