Exploring Consumer Collecting Behavior: A Conceptual Model and Research Agenda

Purpose The purpose of this paper is to explore the behaviors that revolve around collecting, the motivations behind these behaviors and the psychological benefits collectors receive from engaging in these collecting behaviors. Design/methodology/approach A thorough literature review and integration of prominent psychological and social psychology theories are used to propose a conceptual model, several research propositions and potential research questions for future scholarship. Findings This paper proposes that a collector salient identity and collecting motives drive tension-inducing social and solitary collecting behaviors and that these behaviors in turn reinforce the collector salient identity. Relevant aspects of the collecting phenomenon are explored, and included propositions provide future research direction to validate a proposed conceptual model designed to provide insights into a common consumer behavior. Originality/value This paper provides a broad conceptual model and explores several details of consumer collecting behavior as a basis for future research

Secondary Injection of Gases into a Supersonic Flow

The flow field around the injection port for secondary injection of a gas normal to a supersonic stream has been studied in a series of wind-tunnel experiments. The experiments were conducted at freestream Mach numbers of 1.38 to 4.54. Gaseous nitrogen, argon, and helium were used as injectants. New information concerning pressure fields, concentration fields, and shock shapes was obtained. A scale parameter has been calculated, based on a simple, inviscid model of the flow field. This scale parameter gives a good general correlation of the data. Use of this scale parameter allows prediction of a simple scaling law for the side forces generated by secondary injection. This side-force scaling law is in approximate agreement with existing rocket motor test results

Desire Satisfaction Theories and the Problem of Depression

This dissertation argues that the desire satisfaction theory, arguably the dominant theory of well-being at present, fails to explain why depression is bad for a person. People with clinical depression desire almost nothing, but the few desires they do have are almost all satisfied. So it appears the theory must say these people are relatively well-off. A number of possible responses on behalf of the theory are considered, and I argue that each response either fails outright, or requires modifications to the desire satisfaction theory which make the theory unattractive for other reasons.

Boundary-layer and wake measurements on a swept, circulation-control wing

Wind-tunnel measurements of boundary-layer and wake velocity profiles and surface static pressure distributions are presented for a swept, circulation-control wing. The model is an aspect-ratio-four semispan wing mounted on the tunnel side wall at a sweep angle of 45 deg. A full-span, tangential, rearward blowing, circulation-control slot is located ahead of the trailing edge on the upper surface. Flow surveys were obtained at mid-semispan at freestream Mach numbers of 0.425 and 0.70. Boundary-layer profiles measured on the forward portions of the wing are approximately streamwise and two dimensional. The flow in the vicinity of the jet exit and in the near wake is highly three dimensional. The jet flow near the slot on the Coanda surface is directed normal to the slot. Near-wake surveys show large outboard flows at the center of the wake. At Mach 0.425 and a 5-deg angle of attack, a range of jet-blowing rates was found for which an abrupt transition from incipient separation to attached flow occurs in the boundary layer upstream of the slot. The variation in the lower-surface separation location with blowing rate was determined from boundary-layer measurements at Mach 0.425

Aesthetics is the Philosophy of Our Wordless World

For too long, philosophers have tried to force our world to comport to the ‘linguistic turn,’ made famous by Richard Rorty’s 1967 anthology of the same name. And as time marches on, we seem to have even fewer tools at our disposal to carve out alternative views, even though philosophers as varied as Gilbert Ryle and Maurice Merleau-Ponty once discerned our world quite differently. Aesthetics remains the philosophical field where language need not occupy center court. For this reason, Aesthetics matters more than those Realists, who are prone to dismiss non-evidential views, might admit.

Your Tongue Here (Or Not): On Imagining Whether To Take a Bite (Or Not)

Inspired by recent visits to the Disgusting Food Museum (DFM) in Mälmo, SE and “FOOD: Bigger than Your Plate” (2019) at the Victoria & Albert in London, UK, this article explores the saliency of “disgust” given its role in the “attention economy,” hipster allure and emotional encoding. Initially appalled by the DFM’s demonizing national delicacies as disgusting, the author soon realised that doing so has a “silver lining” in terms of attention. One aspect that remains under-explored is the connection between imagination and attention. The relationship between taste and disgust grants us a vehicle for working this out, since human beings are wired for disgust, yet what disgusts is learnt. Unlike basic emotions for which we have salience and/or memories, we deploy our imagination to anticipate disgust. To defeat disgust’s alarmist ploys, “food adventurers” must block their imagination. “Disgusting food” not only grabs people’s attention, but it tends to deceive

Boundary-layer and wake measurements on a swept, circulation-control wing

Wind tunnel measurements of boundary layer and wake velocity profiles and surface static pressure distributions are presented for a swept, circulation control wing. The model is an aspect ratio four semispan wing mounted on the tunnel side wall as a sweep angle of 45 deg. A full span, tangetial, rearward blowing, circulation control slot is located ahead of the trailing edge on the upper surface. Flow surveys were obtained at mid-semispan at freestream Mach numbers of 0.425 and 0.70. Boundary layer profiles measured on the forward portions of the wing are approximately streamwise and two dimensional. The flow in the vicinity of the jet exit and in the near wake is highly three dimensional. The jet flow near the slot on the Coanda surface is directed normal to the slot. Near wake surveys show large outboard flows at the center of the wake. At Mach 0.425 and a 5 deg angle of attack, a range of jet blowing rates was found for which an abrupt transition from incipient separation to attached flow occurs in the boundary layer upstream of the slot. The variation in the lower surface separation location with blowing rate was determined from the boundary layer measurements at Mach 0.425
