Ergonomic Comparison of Four Dental Workplace Concepts Using Inertial Motion Capture for Dentists and Dental Assistants
2021
When the inventory is arranged in a dental practice, a distinction can be made between four different dental workplace concepts (DWCs). Since the prevalence of musculoskeletal diseases in dental professionals is very high, preventive solution need to be investigated. As the conventionally used DWCs have, to date, never been studied in terms of their ergonomics, this study aims to investigate the ergonomic risk when working at the four different DWCs. In total, 75 dentists (37 m/38 f) and 75 dental assistants (16 m/59 f) volunteered to take part in this study. Standardized cooperative working procedures were carried out in a laboratory setting and kinematic data were recorded using an inerti…
Random Slicing: Efficient and Scalable Data Placement for Large-Scale Storage Systems
2014
The ever-growing amount of data requires highly scalable storage solutions. The most flexible approach is to use storage pools that can be expanded and scaled down by adding or removing storage devices. To make this approach usable, it is necessary to provide a solution to locate data items in such a dynamic environment. This article presents and evaluates the Random Slicing strategy, which incorporates lessons learned from table-based, rule-based, and pseudo-randomized hashing strategies and is able to provide a simple and efficient strategy that scales up to handle exascale data. Random Slicing keeps a small table with information about previous storage system insert and remove operations…
Perceptions and behaviour of cruise tourists during their visit to a port of call
2019
[EN] The purpose of the present research is to assess the perceptions of authenticity and crowding of cruise tourists visiting a port of call and its influence on their future behavioural intentions. The research was carried out in the city of Valencia, because it is one of the main Spanish cruise ports and is a representative city of the Mediterranean ports of call for the cruise business. A total of 467 valid interviews were obtained. For the analysis of data, the Statistical Package for the Social Sciences (SPSS version 22.0) was used. The findings reveal that Valencia is perceived as an authentic destination with moderate levels of human and spatial crowding. The analysis also demonstra…
Simultaneous determinations of zirconium, hafnium, yttrium and lanthanides in seawater according to a co-precipitation technique onto iron-hydroxide.
2013
Very low concentrations (pg mL(-1) or sub-pg mL(-1) level) along with the high salinity are the main problems in determining trace metal contents in seawater. This problem is mainly considered for investigations of naturally occurring YLOID (Y and Lanthanides) and Zr and Hf in order to provide precise and accurate results. The inductively coupled plasma mass spectrometry (ICP-MS), both in high and low resolution, offers many advantages including simultaneous analyses of all elements and their quantitative determination with detection limits of the order of pg mL(-1). However in the analysis of YLOID in seawater, a better determination needs an efficient combination of ICP-MS measurement wit…
Dimensions of executive functioning: Evidence from children
2003
This study investigated dimensions of executive functioning in 8- to 13-year-old children. Three tasks from the Cambridge Neuropsychological Test Automated Battery (CANTAB), two tasks from the NEPSY battery and some additional executive function (EF) tests were administered to 108 children. In line with earlier work, modest correlations among EF measures were obtained (r < .4). Both exploratory and confirmatory factor analyses yielded three interrelated factors, which resembled those obtained by Miyake et al. (2000) and which were—with some reservations—labelled Working Memory (WM), Inhibition and Shifting. Age correlated with performance on most individual EF measures as well as Shifting a…
Communication of Dienvidkurzemes region libraries on social media during Covid-19
2022
Jau vairāk nekā desmit gadus dažādas sociālo tīklu vietnes lielai sabiedrības daļai ir kļuvušas par galveno saziņas veidu ar draugiem, radiem, kā arī ar uzņēmumiem un valsts pārvaldes iestādēm, tai skaitā ar bibliotēkām. Covid-19 laiks parādīja to, ka sociālo tīklu vietnes patiesi ir nozīmīgs komunikācijas kanāls daudziem uzņēmumiem un organizācijām. Autores pētījuma mērķis ir noskaidrot, kā Dienvidkurzemes novada publiskajās bibliotēkās mainījās informācijas nodošanas paradumi to klientiem un lietotājiem un vai komunikācija sociālo tīklu vietnēs kļuva aktīvāka. Lai mērķi sasniegtu, autore veica aptaujas ar lietotājiem un bibliotēku darbiniekiem, kā arī tika veikta dokumentu analīze Dienvid…
Impact of the community structure on the dynamics of complex networks
2023
Networks are everywhere. We encounter them daily in our lives, through our social interactions, how we come up with decisions in our brain, to having phone calls, conducting financial transactions, and traveling from one place to another. Individual actions are influenced by their environment, which is, in turn, influenced by the network's topology. Notably, individuals may change their actions, ideas, or opinions to conform to the aspirations of a particular social group. In the same vein, the spread of a virus can take a certain course if the network's structure induces specific pathways for expansion. In such scenarios, communities substantially impact the evolution of the dynamics. They…
Comunicació 2.0 i gènere
2009
Internet ha capgirat les formes de comunicació i d’intercanvi d’informació entre les persones: les receptores en el procés comunicatiu són ara també emissores. La conjunció d’aquesta particularitat amb l’aparició i ús d’algunes eines de comunicació (fàcils d’usar i bàsicament gratuïtes) permet parlar d’un fenomen social de gran abast: la comunicació 2.0. Aquest article analitza algunes de les característiques d’aquesta classe d’interacció i centra l’interés de forma particular en certes iniciatives que tenen com a epicentre les qüestions de gènere. La comunicació 2.0 permet la participació activa i directa en el procés, obert i col·laboratiu, de construcció de la identitat pròpia. Així mate…
Korkeakouludiplomi : kokeiluhankkeen seuranta- ja arviointitutkimuksen väliraportti
2015
Korkeakouludiplomi on opetus- ja kulttuuriministeriön käynnistämä koulutuskokeilu, jonka tarkoituksena on selvittää nykyisiä korkeakoulututkintoja suppeampien koulutusten käyttökelpoisuutta työelämän ja opiskelijoiden kannalta. Korkeakouludiplomikoulutus alkoi syksyllä 2014 pilottihankkeena Jyväskylän ammattikorkeakoulussa ainoana korkeakouluna Suomessa. Tämä julkaisu on väliraportti kokeilun seuranta- ja arviointitutkimuksesta. Siinä kerrotaan opiskelijavalinnasta, koulutuksen organisoinnista, opetussisällöistä ja pedagogista ratkaisuista sekä havainnoista koulutuksen alkuvaiheessa. Raportti perustuu koulutuksen järjestäjien haastatteluihin, raportteihin ja dokumentteihin sekä opiskelijo…
Information potential for some probability density functions
2021
Abstract This paper is related to the information theoretic learning methodology, whose goal is to quantify global scalar descriptors (e.g., entropy) of a given probability density function (PDF). In this context, the core concept is the information potential (IP) S [ s ] ( x ) : = ∫ R p s ( t , x ) d t , s > 0 of a PDF p(t, x) depending on a parameter x; it is naturally related to the Renyi and Tsallis entropies. We present several such PDF, viewed also as kernels of integral operators, for which a precise relation exists between S[2](x) and the variance Var[p(t, x)]. For these PDF we determine explicitly the IP and the Shannon entropy. As an application to Information Theoretic Learning w…
