Unpacking the mechanism by which psychological ownership manifests at the level of the individual: a dynamic model of identity and self

Increasing prominence of the psychological ownership (PO) construct in management studies raises questions about how PO manifests at the level of the individual. In this article, we unpack the mechanism by which individuals use PO to express aspects of their identity and explore how PO manifestations can display congruence as well as incongruence between layers of self. As a conceptual foundation, we develop a dynamic model of individual identity that differentiates between four layers of self, namely, the “core self,” “learned self,” “lived self,” and “perceived self.” We then bring identity and PO literatures together to suggest a framework of PO manifestation and expression viewed through the lens of the four presented layers of self. In exploring our framework, we develop a number of propositions that lay the foundation for future empirical and conceptual work and discuss implications for theory and practice.

Generic construction of monitors for floating point unit designs

This paper proposes a set of well defined steps to design functional verification monitors intended to verify Floating Point Units (FPU) described in HDL. The first step consists on defining the input and output domain coverage. Next, the corner cases are defined. Finally, an already verified reference model is used in order to test the correctness of the Device Under Verification (DUV). As a case study a monitor for an IEEE754-2008 compliant design is implemented. This monitor is built to be easily instantiated into verification frameworks such as OVM. Two different designs were verified reaching complete input coverage and successful compliant results.

Comments on regularization of identity based solutions in string field theory

We analyze the consistency of the recently proposed regularization of an identity based solution in open bosonic string field theory. We show that the equation of motion is satisfied when it is contracted with the regularized solution itself. Additionally, we propose a similar regularization of an identity based solution in the modified cubic superstring field theory.

Construction of Hamiltonian-Minimal Lagrangian submanifolds in Complex Euclidean Space

We describe several families of Lagrangian submanifolds in complex Euclidean space which are H-minimal, i.e. critical points of the volume functional restricted to Hamiltonian variations. We make use of various constructions involving planar, spherical and hyperbolic curves, as well as Legendrian submanifolds of the odd-dimensional unit sphere.

Optimization of incubation time of protein Tc85 in the construction of biosensor: Is the EIS a good tool?

Electrochemical impedance spectroscopy (EIS) in pH 6.9 phosphate buffer solution was used to investigate each step of the procedure employed to modify a screen-printed electrode (SPE). The SPE was modified with self-assembled monolayers (SAMs) of cystamine (CYS, deposited from 20 mM solution), followed by glutaraldehyde (GA, 0.3 M solution). The Trypanosoma cruzi antigen was immobilized using different deposition times. The influence of incubation time (2-18 h) of protein was also investigated. The topography of modified electrode with this protein was investigated by atomic force microscopy (AFM). Interpretation of impedance data was based on physical and chemical adsorption, and degradation of the layer at high and meddle frequencies, and charge transfer reaction involving mainly the reduction of oxygen at low frequencies. EIS studies on modified electrodes with Tc85 protein immobilized for different incubation times indicated that the optimum incubation time was 6-8 h. It was demonstrated that EIS is a good technique to evaluate the different steps and the integrity of the surface modifications, and to optimize the incubation time of protein in the development of biosensors.

Overexpression and Purification of the Oat (Avena Fatua) Protein AFN1 and Construction of a pMAL/AFN1 Expression Plasmid

Abscisic acid (ABA) is an important phytohormone with regulatory roles in many physiological processes. ABA expression is induced by environmental stresses such as drought and it is known to be an inhibitor of seed germination. A wild oat (Avena fatua) called AFN1 has been hypothesized to initiate the early stages of germination as its mRNA accumulates in nondormant seed embryos during imbibition. The polypeptide sequence of AFN1 suggests that it is an ABA glucosyl transferase. Glucosylation by AFN1 and thereby inactivation of ABA could lead to seed germination. In order to understand the role of AFN1 in germination, an ample quantity of AFN1 polypeptide is needed to test for enzymatic ABA glucosylase activity. My work has been to overexpress recombinant AFN1containing a (His)6 tag using a pRSETC E.coli expression system followed by Purification of the AFN1 protein by means of a nickel-affinity column that bind to the (His)6 tag. Due to the insufficient yield of AFN1 fusion protein obtained with this procedure, another method using a pMAL-c2x vector is now being employed. The pMAL expression system provides a method for expressing and purifying protein by tagging proteins with maltose-binding protein (MBP). It is anticipated that MBP tag will be advantageous as it can make the fusion protein more soluble and thereby yield a larger quantity of protein. Currently, work is underway on the construction of pMAL/AFN1 plasmid.

The Cultural Construction of the Maine Sporting Camps

Maine sporting camps were a cultural and social phenomenon of the urban upper and middle class. They originated in Maine in the late 1870s and early 1880s and reached their zenith around the turn of the century with over 160 in operation in eight of the sixteen counties in Maine in 1906. The period from 1880 until World War I can be considered the 'golden era' of the Maine sporting camps. After the war, with technological advancements such as the outboard motor, the proliferation of the automobile, and the introduction of a road system into rural Maine, the camps underwent significant change that warrants an entirely different cultural analysis. A number of elements came together to produce a cultural atmosphere permissive of sporting camp creation in Maine. These include changing national views upon nature, health, sport and the leisure time in which to pursue them. In the late nineteenth century, with the rise of large industrially based cities, overcrowding fostered crime and disease. An upper and middle class emerged that desired escape and separation from the lower classes. Maine was chosen for such an escape because it offered, through sporting camps, a chance to "get back to nature," by pursuing the healthful activities of hunting and fishing. At the same time these urban sportsmen and sportswomen distinguished themselves on the social Hierarchical scale from the rural inhabitants. What happened in rural Maine during the period between 1880 and World War I was the introduction of a new cultural order on the landscape. Coming primarily from urban centers on the East Coast of the United States were men, women and children who looked to Maine for vacations. These vacations were designed to put them in touch with nature by pursuing healthful activities, especially those of fishing and hunting. Coming from an environment that emphasized social standing, they ensured that these trips would perpetuate this hierarchy. They experienced nature through the Maine sporting camps, which provided them with the services and skills necessary to experience it while enjoying a degree of luxury that they were accustomed to in the urban world. The Maine sporting camps were a cultural manifestation of the urban upper and middle class, the groups that the camps were established to serve. Despite this the camps did not represent a structural duplication of urban society. Instead, the camps represented a cultural construction that was produced by interaction between members of two different conceptual and physical worlds, the blending of which, on a social level, was determined by urban mentality and rural knowledge. In the production of a cultural world meaningful to the clients, the rural world of the Maine woods was altered to meet their needs. It was not a one-sided process, however, as the clients were forced to acknowledge the importance of the rural inhabitants on the basis of their value to the clients.
