A PCI Express optical link based on low-cost transceivers qualified for radiation hardness
2013
In this paper we want to demonstrate that an optical physical medium is compatible with the second generation of PCI Express. The benefit introduced by the optical decoupling of a PCI Express endpoint is twofold: it allows for a geographical detachment of the device and it remains compliant with the usual PCI accesses to the legacy I/O and memory spaces. We propose two boards that can bridge the PCI Express protocol over optical fiber. The first is a simple optical translator while the second is a more robust switch developed for connecting up to four devices to a single host. Such adapters are already working in the control and data acquisition system of a particle detector at CERN and hen…
El desarrollo de la organización consciente en equipos: un clima de participación no basta, los equipos necesitan sentir seguridad para realizar prop…
2020
Mindful organizing (also known as collective mindfulness) is a collective capability that allows teams to anticipate and swiftly recover from unexpected events. This collective capability is especially relevant in high-risk environments where reliability in performance is of utmost importance. In this paper, we build on current mindful organizing theory by showing how two front-line communication and participatory conditions (perceived safety for upward dissent and climate for employee engagement) interact to predict mindful organizing. We shed light on the controversy around mindful organizing’s effect on team’s subjective experience at work by showing that it leads to greater …
The importance of horizontal-fit of university student jobs for future job quality
2019
Purpose The purpose of this paper is to gain a better understanding of the antecedents of the quality of graduates’ jobs when they enter the job market after university graduation. Design/methodology/approach Survey data collected from 173 Spanish bachelor and master’s degree university graduates at two time points (two months before and six months after graduation, approximately) were analyzed by means of path analysis. Findings A moderated mediation model was tested, where the relationship between the horizontal fit (HF) between the university degree subject and the student’s job and the quality of the graduate’s job after graduation is mediated by self-perceived employability and modera…
El rol cambiante de los recursos personales en la empleabilidad percibida de los jóvenes en diferentes condiciones del mercado de trabajo
2020
Personal resources and labor market are factors that contribute to perceived employability. However, how changing labor market conditions affect the relationship between personal resources like career enhancing strategies, personal initiative, and career passivity with self-perceived employability remains unclear. Recent events in Spain give an opportunity to examine if personal resources predict perceived employability differently during normal and harsh labor conditions. Two representative samples of young people were surveyed during a normal labor condition (in 2008, before the big recession, n = 1,992) and a harsh condition (in 2011, with 46% young unemployment rate, n = 1,208). …
Negative work reflection, personal resources, and work engagement: the moderating role of perceived organizational support
2018
This day-level study examined the role of perceived organizational support (POS) in the context of employees’ negative work reflection during off-job time. We hypothesized that negative work reflec...
Developing mindful organizing in teams: a participation climate is not enough, teams need to feel safe to challenge their leaders
2020
ABSTRACT Mindful organizing (also known as collective mindfulness) is a collective capability that allows teams to anticipate and swiftly recover from unexpected events. This collective capability is especially relevant in high-risk environments where reliability in performance is of utmost importance. In this paper, we build on current mindful organizing theory by showing how two front-line communication and participatory conditions (perceived safety for upward dissent and climate for employee engagement) interact to predict mindful organizing. We shed light on the controversy around mindful organizing’s effect on team’s subjective experience at work by showing that it leads to…
An OFDM Receiver Exploiting Multipath Diversity
2008
We propose a novel receiver structure, to be employed with standard Orthogonal Frequency Division Multiplexing transmitters, capable of exploiting the multipath diversity of wireless channels. The proposed technique is based on cancellation of inter-block interference arising in the guard interval and linear detection techniques. It features a low implementation complexity and is easily generalized to MIMO systems and non-linear detection techniques.
Go Cashless! Mobile Payment Apps Acceptance in Developing Countries: The Jordanian Context Perspective
2022
Despite the expanding global usage of mobile phones in money transactions, the adoption of mobile payment systems in Jordan remains slow. This study employed the technology acceptance model (TAM) to identify the factors with a potential impact on mobile payment systems acceptance. The impact of perceived privacy (PP) and the mediating function of perceived certainty (PC) on the behavioral intention (BI) of mobile payment systems among Jordanian ministries were examined. Data obtained from 270 respondents were analyzed using partial least-squares structural equation modeling (PLS-SEM). The empirical findings show a positive link between perceived usefulness (PU) and PC on the BI of mobile pa…
Populācijas biomarķieru noteikšana notekūdeņos ar nano-plūsmas šķidrumu hromatogrāfiju- masspektrometriju
2022
Darba gaitā tika ievākti notekūdeņu paraugi no dažādām Latvijas pilsētu (Daugavpils, Jelgava, Jēkabpils, Jūrmala, Liepāja, Rēzekne, Rīga, Salaspils, Tukums, Valmiera un Ventspils) notekūdeņu attīrīšanas iekārtām. Pielietojot nano-plūsmas šķidruma hromatogrāfijas – Orbitrap masspektrometriskās metodi tika veikta populācijas biomarķieru un farmaceitisko līdzekļu satura noteikšana notekūdeņos. Tetrabultiamonija bromīds tika izmantots par jonu pāru reaģentu injekcijas sastāvā, lai uzlabotu polāro analītu sorbciju kolonnā. Veicot paraugu sagatavošanu bez papildu attīrīšanas ar dilute-and-shoot pieeju un izmantojot atšķaidīšanas faktoru 5 tika panākta jutība no 0,005 līdz 0,3 µg/L ar matricas efe…
The stability and functional properties of proteoliposomes mixed with dextran derivatives bearing hydrophobic anchor groups
1992
Liposomes composed of Escherichia coli phospholipid were coated with polysaccharides bearing hydrophobic palmitoyl anchors. The effect on the stability of liposomes without or with integral membrane proteins was investigated. A high concentration of hydrophobized dextrans protected the liposomes against detergent degradation, decreased the fluidity of the membranes, prevented fusion of the liposomes and enhanced their stability. Proteoliposomes containing beef heart cytochrome-c oxidase and the lactose transport carrier of E. coli were similarly affected by coating with the dextrans. Under these conditions both membrane proteins were still active. Long-term stability of the coated liposomes…
