Possessions and the Self: Downstream Consequences of Ownership and Sharing What We Own

My dissertation is based on the premise that possessions are an extension of the self. Beyond simple functional benefits that possessions provide us, I question whether possessions affect our self-perception and behavior. Specifically, I focus on two aspects of possessions: Ownership (Essay 1) and Sharing (Essay 2). In Essay 1, I find that feeling a sense of product ownership has downstream consequences in one’s representation of who s/he is. Here I reveal that salient feelings of product ownership activate a product-related self in one’s mind, but more importantly deactivate product-unrelated self. By identifying simultaneous identity activation and deactivation, I show that an individual can only hold a limited number of salient selves, and activating one’s self aspect requires a trade-off. This finding updates the prior assumption in the literature that an individual can hold an unlimited number of selves, and further suggests that there is still a finite limit to what can be salient at a given time. My interest in ownership extends to Essay 2, where I examine another behavioral aspect of consumers: sharing. Sharing behavior has received much attention lately due to the rise of sharing economy platforms, which provide new opportunities for consumers to share personal belongings with others. In Essay 2, I mine people’s latent motivation behind sharing by using a transaction dataset from one of the largest sharing economy platforms, Airbnb. Here I find that people are driven by not only monetary, but also non-monetary reasons, such as desires to meet others and share the beauty of their homes. Then I explore how each motivation affects people’s engagement on the sharing economy platform and their continued effort to share. This second essay highlights individuals’ new role as micro-entrepreneurs in this new era of the 21st century

The Two Faces of Innovation Adoption: How Envy Affects Consumers' Evaluation of Innovative Products

Employing a dual-process model, four experiments demonstrate that when consumers experience envy, those who are more inclined to attend to their feelings (vs. cognition) are driven by a self-enhancement (vs. self-protection) motive. Accordingly, these envious consumers are more likely to exhibit positive (vs. negative) attitudes toward innovation adoption. [to cite]

Effects of intraoperative inspired oxygen fraction (FiO2 0.3 vs 0.8) on patients undergoing off-pump coronary artery bypass grafting: the CARROT multicenter, cluster-randomized trial

Background To maintain adequate oxygenation is of utmost importance in intraoperative care. However, clinical evidence supporting specific oxygen levels in distinct surgical settings is lacking. This study aimed to compare the effects of 30% and 80% oxygen in off-pump coronary artery bypass grafting (OPCAB). Methods This multicenter trial was conducted in three tertiary hospitals from August 2019 to August 2021. Patients undergoing OPCAB were cluster-randomized to receive either 30% or 80% oxygen intraoperatively, based on the month when the surgery was performed. The primary endpoint was the length of hospital stay. Intraoperative hemodynamic data were also compared. Results A total of 414 patients were cluster-randomized. Length of hospital stay was not different in the 30% oxygen group compared to the 80% oxygen group (median, 7.0 days vs 7.0 days; the sub-distribution hazard ratio, 0.98; 95% confidence interval [CI] 0.83–1.16; P = 0.808). The incidence of postoperative acute kidney injury was significantly higher in the 30% oxygen group than in the 80% oxygen group (30.7% vs 19.4%; odds ratio, 1.94; 95% CI 1.18–3.17; P = 0.036). Intraoperative time-weighted average mixed venous oxygen saturation was significantly higher in the 80% oxygen group (74% vs 64%; P < 0.001). The 80% oxygen group also had a significantly greater intraoperative time-weighted average cerebral regional oxygen saturation than the 30% oxygen group (56% vs 52%; P = 0.002). Conclusions In patients undergoing OPCAB, intraoperative administration of 80% oxygen did not decrease the length of hospital stay, compared to 30% oxygen, but may reduce postoperative acute kidney injury. Moreover, compared to 30% oxygen, intraoperative use of 80% oxygen improved oxygen delivery in patients undergoing OPCAB. Trial registration ClinicalTrials.gov (NCT03945565; April 8, 2019)

The Social Consequences of Envy

We find that feelings of envy lead to greater escaping behavior from the envied target. Three experiments show that envious individuals, particularly those with high dispositional attention-to-feelings, perceive themselves to be less similar to the envied individual and to pursue different values in life, and exhibit more unique consumption preferences.

Ownership and identity : a cognitive perspective

This chapter demonstrates that identity-related connections that consumers form with possessions profoundly affect judgment and behavior. The authors first outline the implications of ownership for product-relevant domains from the lens of egocentric categorization theory (ECT). ECT explains when and how: (1) the material environment affects consumer judgments and decisions about the self; and (2) the self affects judgments and decisions about material objects. According to ECT, consumers categorize products relative to the self, based on ownership. Consumers then judge the self in assimilation or contrast to material objects, as well as judge material objects in assimilation or contrast to the self. The authors then describe the “see-saw self” model that highlights the implications of ownership for product-irrelevant domains: Product ownership not only affects identity behavior in product-relevant domains, but also deactivates identities in product-irrelevant domains. This identity-deactivation results in impaired performance on tasks in product-irrelevant domains. The authors propose avenues for future identity researc

A dynamic control approach for energy-efficient production scheduling on a single machine under time-varying electricity pricing

This paper proposes a dynamic control algorithm to enable an energy-aware single machine scheduling under the time-varying electricity pricing policy, in which price rates remain fixed day-to-day over the season. The key issue is to assign a set of jobs to available time periods where different electricity prices are assigned, while considering requested due dates of jobs so as to minimize total penalty costs for earliness and tardiness of jobs and total energy consumption costs, simultaneously. As the first contribution of this study, we develop a new mixed integer nonlinear programming (MINLP) model that aims at determining job arrival times and resulting earliness and tardiness of jobs and energy consumption costs for machine idle and normal processing. Second, an efficient heuristic approach based on continuous-time variable control models and algorithm is developed. The proposed heuristic adaptively changes job arrival times and due dates, which finally determine production sequence over the time periods of different electricity prices, machine turn-off, and machine idle with minimum energy consumption costs and just-in-time (JIT) penalty. Energy and JIT performance of the proposed approach is examined using real energy and machining parameters of a HAAS machine and compared to those of the metaheuristic approach. For relatively large size data groups, the proposed approach incurs about 4∼11% higher energy consumption costs on average, which are offset by up to 99% lower JIT costs, resulting in 10∼94% lower total costs on average compared to the metaheuristic approach. The proposed time-scaled heuristic algorithm yields extremely short computational time, which enables production managers to flexibly select proper production strategies and to implement them for different production environments
