Perceived Benefit From Hearing Aid Use and Life-Space Mobility Among Community-Dwelling Older Adults

2018

Objectives: To examine the association between perceived benefit from hearing aid (HA) use and life-space mobility among older adults. Method: Cross-sectional analysis of 76- to 91-year-old community-dwelling adults ( n = 702). Data on perceived hearing with and without a HA were obtained via postal questionnaire and data on life-space mobility (Life-Space Assessment, range = 0-120) via phone interview. Results: Participants who perceived more benefit from HA use, had a better life-space mobility score ( M = 65, SD = 2.6) than participants who had less benefit from using a HA ( M = 55, SD = 3.2). Participants who benefitted more from HA use did not differ from those who did not have a HA (…

Infection of Soybean Plants with the Insect Bacterial Symbiont Burkholderia gladioli and Evaluation of Plant Fitness

2017

To investigate the establishment and consequences of host-microbe interactions, it is important to develop controlled infection assays suitable for each system, as well as appropriate methods to evaluate successful infection and its associated effects. Here, we describe a procedure for bacterial inoculation of soybean plants, followed by the assessment of systemic infection and impact on plant fitness. Soybean (Glycine max) seedlings were mechanically wounded using a device that mimics insect herbivory and inoculated with known cell numbers of Burkholderia gladioli bacteria previously isolated from an insect host. The impact on the plants was evaluated by monitoring changes in height, time …

Dispersion Interaction between Two Hydrogen Atoms in a Static Electric Field

2019

We consider the dispersion interaction between two ground-state hydrogen atoms, interacting with the quantum electromagnetic field in the vacuum state, in the presence of an external static electric field, both in the nonretarded and in the retarded Casimir-Polder regime. We show that the presence of the external field strongly modifies the dispersion interaction between the atoms, changing its space dependence. Moreover, we find that, for specific geometrical configurations of the two atoms with respect to the external field and/or the relative orientation of the fields acting on the two atoms, it is possible to change the character of the dispersion force, turning it from attractive to re…

Vacuum local and global electromagnetic self-energies for a point-like and an extended field source

2013

We consider the electric and magnetic energy densities (or equivalently field fluctuations) in the space around a point-like field source in its ground state, after having subtracted the spatially uniform zero-point energy terms, and discuss the problem of their singular behavior at the source's position. We show that the assumption of a point-like source leads, for a simple Hamiltonian model of the interaction of the source with the electromagnetic radiation field, to a divergence of the renormalized electric and magnetic energy density at the position of the source. We analyze in detail the mathematical structure of such singularity in terms of a delta function and its derivatives. We als…

Audit Committee Independence and Auditor-Manager Disputes

2020

This paper analyzes the role of audit committee independence in resolving disagreements between management and the auditor regarding financial reporting. The common intuition suggests that the audit committee must be independent from management to be able to support the auditor against the manager's manipulation attempts. We build a one-period strategic model to show that this intuition is valid only if overinvestment is a bigger concern to shareholders than underinvestment. Otherwise, any audit committee will agree with management to avoid underinvestment. The audit committee's optimal independence level, which can be fully independent or partially dependent, is affected by investment effi…

Artesanado sedero y capital comercial en la Valencia del siglo XVIII

1997

The intense development of the «Verlagssystem» in the XVIII century silk industry in Valencia showed the difficulties of the traditional craftsmen to keep their economic independence. In order to fighy against it, the craftsmen adopted several initiatives, which dealt with the constitution of a share-holding company, as much as with the creation of a communal store to favour the suppley of raw materials to the factories. The most important project was the constitution of the «Compañía de Nuestra Señora de los Desamparados» in 1772. But the requirement of the General Board of Commerce to allow all the social classes to take part in shareholders, as it was not accompanied by the modification …

Stakeholder relations as social capital in early modern international trade

2008

Stakeholder relations that are available through networks of various sorts are one benefit from social capital. According to the stakeholder approach to organisations, those relationships that contain most of the important attributes – such as power, legitimacy, frequency of contact and urgency – hypothetically dominate the business environment. This has caused modern corporations to view chiefly the dominant stakeholders as important. This study tests the importance of these attributes in early modern international trade; in other words, which attributes played a major role in the relations between Finnish tradesmen and their foreign contacts? The archives of two major Finnish trading hous…

The Impact of Macroeconomic Variables on Corporate Performance - What Shareholders Ought to Know?

2002

Increased integration and growing macroeconomic fluctuations require more attention to be paid to the link between the "noise" that these fluctuations represent and the company's own development. For many reasons management must weed out the effects of the "noise" so as to obtain a clear picture of the long-term sustainable profits, and thus a picture of how the company's intrinsic competitiveness is fostered. An understanding of the effects of the fluctuations also provides the basis for risk assessment. How far, then, should this "new" view of corporate performance be extended to outsider shareholders? Current reporting practice does not provide these shareholders with an adequate idea of…
