Understanding the challenges of rapid digital transformation : the case of COVID-19 pandemic in higher education

2021

Rapid digital transformation is taking place due to the COVID-19 pandemic, forcing organisations and higher educational institutions to change their working and learning culture. This study explores the challenges of rapid digital transformation arising during the pandemic in the higher education context. This research used the Q-methodology to understand the nine challenges that higher education encountered, perceived differently as four main patterns: (1) Digital-nomad enterprise; (2) Corporate-collectivism; (3) Well-being-oriented; and (4) Pluralistic. This study broadens the current understanding of digital transformation, especially in higher education. The nine challenges and four pat…

Agents driven smart sensors

2017

Any physical area (like schools, home, hospitals etc.) that uses either mobile devices, sensors, embedded systems or computers to gather information from the users and the environment and eventually, adapt according to the new information gained. [1] Smart spaces compromises of heterogeneous hardware which often leads to the issues of interoperability. One way of reducing the heterogeneity between the sensors is to introduce the semantic interface as sensors default interface. Semantic Web provides a common interface and for-mat for data representation so that one can decrease the heterogeneity of data and increase data reusability. [2] With the Smart Spaces, it is important to use only the…

Escaping scaling relationships for water dissociation at interfacial sites of zirconia-supported Rh and Pt clusters

2019

<p>Water dissociation is an important reaction involved in many industrial processes and a good model reaction for probing the activity of catalytic sites. In this computational study, the dissociation of water at interfacial sites of globally optimized ZrO2 sup- ported Pt and Rh clusters is investigated under the framework of density functional theory. Our findings demonstrate that the perimeter sites of these small clusters can activate water, but the dissociation behavior varies considerably between sites. It is shown that the studied clusters break scaling relationships for water dissociation, suggesting these catalysts may achieve activities beyond the maximum imposed by such rel…

Sensorineural Hearing Loss: Pathophysiology, Diagnosis and Treatment [Chapter 5. Neuroradiology of the Hearing System]

2019

Hearing loss is one of the most frequent indications for CT and MR examinations of the auditory system. Such a symptomatology is becoming increasingly common in today’s society and is extremely disturbing for patients. Causes may involve the auditory pathway at any level. In most cases, neuroradiological examinations represents a mandatory step, within a multidisciplinary workup, towards final diagnosis, therapeutic plan and subsequent follow-ups. This chapter will introduce this critical topic starting from an imaging-based exposition of the anatomy and function of the auditory system. The chapter will include some hints on the choice of the best imaging examination to perform on each pati…

2019

SEC 2017: Congreso de las Enfermedades Cardiovasculares Introducción y objetivos No se dispone de tratamientos farmacológicos que demuestren reducir la morbimortalidad asociada en pacientes con insuficiencia cardiaca y función sistólica conservada (IC-FEc). El objetivo del presente estudio fue evaluar si en pacientes con IC-FEc, el entrenamiento de la musculatura inspiratoria (EMI), la electroestimulación muscular funcional (EMF) o la combinación de ambas (EMI + EMF) puede mejorar la capacidad funcional, calidad de vida, parámetros de disfunción diastólica o biomarcadores a las 12 y 24 semanas. Métodos Un total de 61 pacientes estables con IC-FEc (clase funcional de la New York Heart Associ…

Features of W production in p-p, p-Pb and Pb-Pb collisions

2017

We consider the production of inclusive W bosons in variety of high-energy hadronic collisions: p--p, p--$\overline{\rm p}$, p--Pb, and Pb--Pb. In particular, we focus on the resulting distributions of charged leptons from W decay that can be measured with relatively low backgrounds. The leading-order expressions within the collinearly factorized QCD indicate that the center-of-mass energy dependence at forward/backward rapidities should be well approximated by a simple power law. The scaling exponent is related to the small-$x$ behaviour of the quark distributions, which is largely driven by the parton evolution. An interesting consequence is the simple scaling law for the lepton charge as…

First measurement of the |t|-dependence of coherent J/ψ photonuclear production

2021

The first measurement of the dependence on $|t|$, the square of the momentum transferred between the incoming and outgoing target nucleus, of coherent J/ψ photoproduction is presented. The data were measured with the ALICE detector in ultra-peripheral Pb-Pb collisions at a centre-of-mass energy per nucleon pair $\sqrt{s_{\rm NN}} = 5.02$ TeV with the J/$\psi$ produced in the central rapidity region $|y| < 0.8$, which corresponds to the small Bjorken-$x$ range $(0.3 − 1.4) \times 10 ^{−3}$. The measured $|t|$-dependence is not described by computations based only on the Pb nuclear form factor, while the photonuclear cross section is better reproduced by models including shadowing according t…

Lime dusts as a source of environmental pollution in Opole Province

2010

Pyły powstające przy produkcji wapna uważano za nieszkodliwe dla środowiska i w związku z tym były one badane marginalnie, szczególnie jeśli chodzi o właściwości magnetyczne i zawartość metali ciężkich. Celem prezentowanych badań było uzupełnienie luki w tym zakresie. Badania obejmowały pomiary podatności magnetycznej, zawartości minerałów ferrimagnetycznych, metali ciężkich, pH i konduktywność pyłów wapienniczych, a także surowca i paliwa, używanego do produkcji wapna. Próbki zostały pobrane w jednym z zakładów wapienniczych województwa opolskiego. Podobne badania wykonano także dla pyłów pobranych w pobliskiej cementowni stosującej suchą metodę produkcji cementu. Wykazano, że podatność ma…
