Applicants reactions to selection procedures : prediction uncertainty as a moderator of the relationship between procedural fairness and organizational attractiveness

Prozedurale Fairnessbewertungen beeinflussen in starkem Maße Einstellungen und das Verhalten von Personen gegenüber Organisationen. Dies gilt auch für die Bewertung von Personalauswahlverfahren. Personen, die ein Auswahlverfahren als fair einschätzen, bewerten die betreffende Organisation auch als attraktiveren Arbeitgeber. Die vorliegende Studie untersuchte, in wieweit dispositionale Vorhersageunsicherheit auf Seiten der Bewerbenden diesen Zusammenhang verstärkt. Die Ergebnisse der Studie demonstrieren in Abhängigkeit von der Auswahlentscheidung unterschiedliche moderierende Einflüsse von Vorhersageunsicherheit auf den Zusammenhang zwischen prozeduraler Fairnessbewertung und organisationaler Attraktivität. Implikationen für die Forschung zum Einfluss von Fairnessbewertungen sowie für die Anwendung im organisationalen Kontext werden diskutiert

Radio Dispatching Communications During a Mass Event - A Case Studies of the “Lednica 2000” Youth Meetings

In paper we present two case studies of the wireless dispatching communications. The first one aims at providing voice service and FM radio broadcasting during mass events of the “Lednica 2000” Youth Meetings. The presentation is supported by over 20-year experience in organization of this event every year. In the second use study we analyze evolution of the dispatching networks in the energy sector. These networks can be used by PPDR agencies in the situation of disasters and other crisis occurrences

Applicants’ reactions to selection procedures – Prediction uncertainty as a moderator of the relationship between procedural fairness and organizational attractiveness

Procedural fairness judgments strongly influence peoples’ attitudes and behaviors towards organizations. This is also true for the evaluation of selection systems. People who perceive a selection procedure as fairer judge the respective organization as a more attractive employer. The present study examined whether this relationship is strengthened by applicants’ prediction uncertainty. Results demonstrate a differential moderating effect of prediction uncertainty on the relationship between procedural fairness judgments and organizational attractiveness, depending on the outcome of the application. Implications for research on fairness judgments as well as applications in organizational settings are discussed.

Distribution of the sheet current in a magnetically shielded superconducting filament

The distribution of the transport current in a superconducting filament aligned parallel to the flat surface of a semi-infinite bulk magnet is studied theoretically. An integral equation governing the current distribution in the Meissner state of the filament is derived and solved numerically for various filament-magnet distances and different relative permeabilities. This reveals that the current is depressed on the side of the filament adjacent to the surface of the magnet and enhanced on the averted side. Substantial current redistributions in the filament can already occur for low values of the relative permeability of the magnet, when the distance between the filament and the magnet is short, with evidence of saturation at moderately high values of this quantity, similar to the findings for magnetically shielded strips.Comment: 11 pages, 5 figures; submitted to Physica

Strong reduction of ac losses in a superconductor strip located between superconducting ground plates

The problem of calculating the ac losses in a superconductor strip with a transport current placed inside superconducting environments is studied analytically in the frame of the critical state model. Exact results obtained by the method of images for the commonly employed flat ground plates are used to derive power losses and, consequently, the nonlinear resistance depending on the ac frequency, current amplitude and the distance to the ground plates. The resistance is strongly reduced when the distance between the strip and the shields becomes small.Comment: 10 pages, 3 figure

Magneto-optical investigations of Ag-sheathed Bi-2223 tapes with ferromagnetic shielding

An increase in the critical current and suppression of AC losses in superconducting wires and tapes with soft magnetic sheath have been predicted theoretically and confirmed experimentally. In this work we present the results of magneto-optical investigations on a series of Ag-sheathed Bi-2223 tapes with Ni coating. We visualize distributions of magnetic field at increasing external field and different temperatures, demonstrating a difference between the flux propagation in the superconductor with Ni rims and a reference sample without Ni coating.Comment: 2 page

Populations of doubled haploids for genetic mapping in hexaploid winter triticale.

To create a framework for genetic dissection of hexaploid triticale, six populations of doubled haploid (DH) lines were developed from pairwise hybrids of high-yielding winter triticale cultivars. The six populations comprise between 97 and 231 genotyped DH lines each, totaling 957 DH lines. A consensus genetic map spans 4593.9 cM is composed of 1576 unique DArT markers. The maps reveal several structural rearrangements in triticale genomes. In preliminary tests of the populations and maps, markers specific to wheat segments of the engineered rye chromosome 1R (RM1B) were identified. Example QTL mapping of days to heading in cv. Krakowiak revealed loci on chromosomes 2BL and 2R responsible for extended vernalization requirement, and candidate genes were identified. The material is available to all parties interested in triticale genetics

Lessons Learned from WiMAX Deployment at INEA, Journal of Telecommunications and Information Technology, 2014, nr 3

me broadband access is continuously demanding more bandwidth fueled by video streaming, entertainment and gaming applications. In 2010, a company INEA decided to roll-out new WiMAX-based services aimed to meet the needs of home users across theWielkopolska region of western Poland. It was decided to follow the 802.16e standard and the Time Division Duplexing (TDD) mode that offer the ability to adjust the downlink/uplink ratio and thus are well suited for data transmission. After an extensive testing period of equipment from various vendors, engineers at INEA have chosen the Motorola (currently Cambium Networks) PMP320 solution because it is compact and its components are space- and energy-effcient. The company choice was also influenced by its simple operation, management and installation, which ensured low costs of ownership. So far, this deployment has provided fast and affordable connectivity for Internet and telephony services to around 5,500 households across the 30,000 sq. km region. After 3 years of experience, INEA would like to share the lessons learned from this roll-out
