Cross-border Entrepreneurial Education, Development and Knowledge and Technology Transfer: Experiences with the Cambridge–Riga Venture Camp Programme…

2021

Over a 6-year period, a collaboration has been developed between a group in Cambridge, UK, and two Latvian Universities, Stockholm School of Economics in Riga and other organisations, including Riga City Council, supported by the British Embassy Riga and the Latvian Embassy in London, enabling structured processes to be developed to identify aspiring entrepreneurs based in Latvia and Estonia and provide education, coaching, mentoring and encouragement first in the home territory, leading to an intense whole-week development venture camp in Cambridge for selected candidates. The programme was extended to provide ongoing business development support for a number of entrepreneurial companies w…

La organización y la gestión en los servicios sociales: el trabajador social en la organización y gestión de los servicios sociales

2010

En este artículo se pretende fomentar la reflexión de las y los trabajadores sociales en temas que no han sido considerados prioritarios entre las funciones a desarrollar desde el trabajo social y que sin embargo son elementos de primera necesidad si queremos hacer perdurar el sistema de servicios sociales, en el que una parte importante de la profesión desarrolla su actividad. Dotar a las unidades, departamentos, servicios, áreas en las que se trabaja de una estructura de organización y gestión que favorezca la consolidación del sistema, poner en valor la gestión del conocimiento, abordar el tema de introducir parámetros de calidad en los servicios que prestamos, establecer procesos y defi…

Statins and the squalene synthase inhibitor zaragozic acid stimulate the non-amyloidogenic pathway of amyloid-beta protein precursor processing by su…

2010

Cholesterol-lowering drugs such as statins influence the proteolytic processing of the amyloid-beta protein precursor (AbetaPP) and are reported to stimulate the activity of alpha-secretase, the major preventive secretase of Alzheimer's disease. Statins can increase the alpha-secretase activity by their cholesterol-lowering properties as well as by impairment of isoprenoids synthesis. In the present study, we elucidate the contribution of these pathways in alpha-secretase activation. We demonstrate that zaragozic acid, a potent inhibitor of squalene synthase which blocks cholesterol synthesis but allows synthesis of isoprenoids, also stimulates alpha-secretase activity. Treatment of human n…

'I love Rock 'n' Roll'--music genre preference modulates brain responses to music.

2013

The present study examined the effect of participants' music genre preference on the neural processes underlying evaluative and cognitive judgements of music using the event-related potential technique. To this aim, two participant groups differing in their preference for Latin American and Heavy Metal music performed a liking judgement and a genre classification task on a variety of excerpts of either music genre. A late positive potential (LPP) was elicited in all conditions between 600 and 900 ms after stimulus onset. During the genre classification task, an early negativity was elicited by the preferred compared to the non-preferred music at around 230-370 ms whereas the non-preferred g…

Pressure dependence of the optical properties of wurtzite and rock-salt Zn1–xCoxO thin films

2007

In this paper we investigate the electronic structure of Zn 1-x Co x O by means of optical absorption measurements under pressure. Thin films of Zn 1-x Co x O with different Co content (from 1 to 30%) were prepared by pulsed laser deposition on mica substrates. Absorption spectra exhibit three main features that are clearly correlated to the Co content in the films: (i) absorption peaks in the infrared associated to crystal-field-split internal transitions in the Co 3d shell, with very small pressure coefficients due to their atomic character; (ii) a broad absorption band below the fundamental edge associated to charge transfer transitions, that exhibit relatively large pressure coefficient…

Structural Properties and Temperature Behaviour of Optical Absorption Edge in Polycrystalline ZnO:X (Cu,Ag) Films

2013

Silver- and copper-doped ZnO lms were prepared by radio-frequency magnetron sputtering on glass substrates. The in uence of dopants content on the structural, morphological properties as well as on evolution of the optical absorption edge was considered. It has been found that Ag- and Cu-doped ZnO lms are characterized by wurtzite crystalline structure with the preferred direction of crystalline orientation (002). The sizes of grains within the lms were found to be dependent on the type of dopant. The temperature evolution of the optical absorption edge is described by the modi ed Urbach rule that re ects polycrystalline nature of the material. The corresponding parameters concerning electr…

Interpretation of the Ni K-edge EXAFS in nanocrystalline nickel oxide using molecular dynamics simulations

2011

Abstract Analysis of atomic structure at the nanoscale is a challenging task, complicated by relaxation phenomena and thermal disorder. In this work, the x-ray absorption spectroscopy at the Ni K-edge was used to address this problem in nanocrystalline NiO (nano-NiO) at 300 K. The analysis of the first two coordination shells using conventional two-shell single-scattering approximation allowed us to determine the expansion of the average lattice but contraction of the Ni―O bonds in the first coordination shell in nano-NiO in comparison with the bulk nickel oxide. The EXAFS signal generated within the first six coordination shells (up to ~ 6.5 A) was successfully interpreted using classical …

The need to grow, learn and develop – how does management affect motivation for professional development?

2018

This article argues that knowledge management and social recognition is important for organisational learning and professional self-esteem in academic libraries. An anonymous survey was issued in 2016 to investigate how library staff’s self-esteem is affected by how they experience their management’s view and overview of their knowledge. The need for what Axel Honneth refers to as social recognition will also be discussed as an important part of how professional self-esteem and work satisfaction is experienced and further how this affects motivation to participate in professional development.

Transition-Edge Sensors for Particle Induced X-ray Emission Measurements

2013

In this paper we present a new measurement setup, where a transitionedge sensor detector array is used to detect X-rays in particle induced X-ray emission measurements with a 2 MeV proton beam. Transition-edge sensors offer orders of magnitude improvement in energy resolution compared to conventional silicon or germanium detectors, making it possible to recognize spectral lines in materials analysis that have previously been impossible to resolve, and to get chemical information from the elements. Our sensors are cooled to the operation temperature (65 mK) with a cryogen-free adiabatic demagnetization refrigerator, which houses a specially designed X-ray snout that has a vacuum tight window…
