Wykorzystanie ram jakości M.J. Epplera do ewaluacji jakości informacji serwisów internetowych PWSZ

2019

The article presents the evaluation of information quality on the websites of the State Higher Vocational Schools (PWSZ) in Poland. The information quality framework proposed by M.J. Eppler was adopted as a diagnostic tool to identify gaps in information quality. The assessment was conducted from the user's perspective. Firstly, the ranking of the PWSZ sites in Poland was created. Secondly, the criteria for the quality of information in the website infrastructure were analysed. The conclusions result in a statement that most websites demonstrate a low level of information quality. The scope of synthetic measures ranges from 60.0% to 90.8% which indicates a wide variation in the information …

Modification of the subcontinental mantle beneath East Serbia: Evidence from orthopyroxene-rich xenoliths

2007

Orthopyroxene-rich olivine websterite xenoliths (OWB2) in Palaeogene basanites in East Serbia are mostly composed of tabular low-Al2O3 orthopyroxene (> 70 vol.%, Mg# 85–87) containing tiny Cr spinel inclusions. Orthopyroxene shows a slightly U-shaped primitive mantle-normalized trace element pattern with strong peaks at U and Pb, similar to that of orthopyroxene from normal regional peridotitic mantle. In between the orthopyroxenes are interstitial spaces composed of partially altered olivine (Mg# 85–87), clinopyroxene, Ti-rich spinel, Mg-bearing calcite, K-feldspar, apatite, ilmenite and relicts of a hydrous mineral. Clinopyroxene appears as selvages around orthopyroxene and as coarser euh…

Contrasting types of metasomatism in dunite, wehrlite and websterite xenoliths from Kimberley, South Africa

2008

Abstract Dunite, wehrlite and websterite are rare members of the mantle xenolith suite in the Kimberley kimberlites of the Kaapvaal Craton in southern Africa. All three types were originally residues of extensive melt extraction and experienced varying amounts and types of melt re-enrichment. The melt depletion event, dated by Re–Os isotope systematics at 2.9 Ga or older, is evidenced by the high Mg# (Mg/(Mg + Fe)) of silicate minerals (olivine (0.89–0.93); pyroxene (0.88–0.93); garnet (0.72–0.85)), high Cr# (Cr/(Cr + Al)) of spinel (0.53–0.84) and mostly low whole-rock SiO2, CaO and Al2O3 contents. Shortly after melt depletion, websterites were formed by reaction between depleted peridotit…

Advance booking across channels: The effects on dynamic pricing

2021

This research analyzes the effects of advance booking and channel type on hotel rates. While this relationship has been addressed in the literature, most studies take a partial approach by focusing only on one distribution channel or one destination. This study fills this gap by analyzing the price dynamics for four channels and multiple destinations. The data set consists of 39,363 bookings for 1085 hotels over 27 consecutive months. We used two-stage least squares to solve potential endogeneity issues, and the results proved that distribution channel, hotel type and hotel size have an influence on the effect of advance booking on hotel rates. Critical managerial implications are discussed…

Anglicisms in Tourism Language Corpora 2.0

2015

Abstract The world of tourism has evolved in recent times because of the impact of the Internet. Tourism enterprises have expanded their commercial point of view and have found a faster way to reach clients through increased tourism advertising on the Web. Along with this increase in advertising are the opportunities to study the lexicon of tourism. One of the main points in this lexicon is the use of foreign words, especially the use of Anglicisms due to English's status as a universal language in these contexts. In this article, we will study the Anglicisms in Spanish tourism from these points of view: • why these words are used; • in what context they are used; • if we use original forei…

Assessing anthropogenic pressures on coastal marine ecosystems using stable CNS isotopes: State of the art, knowledge gaps, and community-scale persp…

2015

Abstract In recent decades, the analysis of carbon, nitrogen and sulfur stable isotopes (SIA) has emerged as a powerful, viable methodology for examining food web structure and dynamics, as well as addressing a number of applied issues. Here, we provide a state-of-the-art review of the use of SIA for assessing anthropogenic pressures on natural ecosystems, in order to establish current knowledge gaps and identify promising applications for evaluating the ecological status of marine coastal waters. Specifically, the potential of SIA to provide food web-scale indicators for estimating cumulative anthropogenic pressures is addressed. The review indicates that the methodology has been used for …

COMPORTAMENTO DI IMPALCATI DA PONTE A CASSONE IN ACCIAIO-CALCESTRUZZO CON ANIMA ONDULATA

2013

La memoria riguarda il comportamento di un impalcato di ponte stradale a cassone avente le anime sagomate secondo una sinusoide, con soletta in c.a. collaborante. L'impalcato presenta schema statico longitudinale di trave continua su 4 appoggi. The paper concerns the behaviour of a box-girder bridge deck road having a steel box and a concrete slab. The steel webs are shaped according to a sine wave. The deck has a width of 13.70 m and a length of 182 m, with the longitudinal static scheme as a continuous beam on four supports. The study highlights the reliability of this constructive solution.

A closed formula for the evaluation of foams

2020

International audience; We give a purely combinatorial formula for evaluating closed, decorated foams. Our evaluation gives an integral polynomial and is directly connected to an integral, equivariant version of colored Khovanov-Rozansky link homology categorifying the sl(N) link polynomial. We also provide connections to the equivariant cohomology rings of partial flag varieties.

Preferencias implícitas de una muestra española: una técnica novedosa para determinar preferencias raciales

2015

Las preferencias raciales expresadas explícitamente pueden carecer de información que sea completa en su contenido, ya sea porque las personas prefieren no expresar sus actitudes per se o tal vez porque no estén al tanto de ellas. El Implicit Association Test (IAT), desarrollado por Greenwald, Banaji y Nosek, evalúa las preferencias implícitas de las personas a través de una plataforma de internet. Demuestra que cuando una persona expresa una preferencia en particular, es posible que no conciba que esa actitud tenga un componente inconsciente y que pueda modificarla. Se obtuvieron 235 sujetos que respondieron a la prueba de preferencia implícita de raza (negra y blanca), a través del portal…
