An account is given of visual and infrared observations made of Amor asteroid 1982 DV during its discovery apparition. Broadband visual and near-infrared photometry shows it to be an S-class asteroid. Narrowband spectrophotometry shows an absorption…

This study examined the relationships of normative and affective facets of organizational commitment with experienced burnout within the framework of the Confucian-based Chinese culture. Data for this exploratory work were collected through a…

We report Arecibo (2380-MHz, 13-cm) observations of Asteroid 1580 Betulia in May June 2002. We combine these continuous-wave Doppler spectra and delay-Doppler images with optical lightcurves from the 1976 and 1989 apparitions in order to estimate…

Diameters and geometric albedos are derived from 10- and 20-micron infrared photometry for 84 asteroids, 68 of them not previously observed in this program of asteroid radiometry. All but three of the 30 brightest asteroids are included in the total…

Dung beetle populations, in decline, play a critical ecological role in extensive pasture ecosystems by recycling organic matter; thus the importance of their conservation status. Presence data available for Copris hispanus (L.) and Copris lunaris…

The perceived obligations of the two parties to the employment relationship, the employee and the organization, were explored using the critical incident technique. Incidents were elicited which exceeded or fell below the treatment which each party…

The short-lived radionuclide 26Al existed throughout the solar nebula 4.57 Ga ago, and the initial abundance ratio (26Al/27Al)0, as inferred from magnesium isotopic compositions of calciumaluminum-rich inclusions (CAIs) in chondritic meteorites, has…

Small- and medium-sized enterprises (SMEs) play an important role in today's global economy. However, there are significant differences in how they respond to the opportunities and threats in international markets. This study suggests SMEs'…

We present V and R photometry of 16 Kuiper belt objects (KBOs) from the 3.6-m Telescopio Nazionale Galileo and the Complejo Astronómico El Leoncito 2.1-m telescope. We find a wide dispersion in the (VR) colors of the objects, indicating nonuniform…

The conservation of biodiversity in Europe is defined by Directive 92/43/EEC - commonly known as the Habitats Directive - relating to the conservation of natural habitats and of wild flora and fauna. This Directive established the creation of an…

Abstract: As the field of employee branding has begun to unfold, more and more executives have become interested in how this process can help them achieve a competitive advantage for their organizations. This article explains how employee branding…

In light of global remotely sensed data, the igneous crust of the Moon can no longer be viewed as a simple, globally stratified cumulus structure, composed of a flotation upper crust of anorthosite underlain by progressively more mafic rocks and a…

Contraction of skeletal muscle is triggered by the release of Ca2+ from the sarcoplasmic reticulum (SR) after depolarization of transverse tubules. The ryanodine receptor exists as a 'foot' protein in the junctional gap between the sarcoplasmic…

The dust disks observed around mature stars are evidence that plantesimals are present in these systems on spatial scales that are similar to that of the asteroids and the KBOs in the Solar System. These dust disks (a.k.a. ``debris disks'') present…
