Early Career Women in Academia: An Exploration of Networking Perceptions
2016
This chapter explores women’s networking perceptions by focusing on early career women in social sciences. Within an exploratory research design it asks how early career women define the early career stage in academia, what definitions, meanings and interpretations they give for networks and networking, how they construct the networking process and their ability to establish and/or join networks, as early career researchers and as women. Based on two group interviews with 12 participants, our findings show that early career women in academia favour networking with peers based on shared interests (organic networking). At the same time though, they challenge and step over the perceived gender…
Vammaisuuden sukupuolittuneet ja sortavat diskurssit : yhteiskunnallis-diskursiivinen näkökulma vammaisuuteen
2007
Väitöstyössään Marjo-Riitta Reinikainen tutkii kriittisellä otteella tavanomaista arkista puhetta vammaisuudesta. Huomion kohteena ovat vammaisuudelle ja vammaisena olemiselle teksteissä annetut merkitykset, erityisesti näiden sukupuolittuneet sekä vammaisten sortoa ja syrjintää tuottavat ja ylläpitävät muodot. Reinikaisen tutkimissa teksteissä vammainen mies kuvataan usein oletettujen positiivisten ominaisuuksiensa, kykyjensä ja saavutustensa kautta, kun taas vammainen nainen kuvataan pikemminkin menetystensä ja puutteidensa kautta. – Kun vammaispuhetta tarkastellaan sukupuolinäkökulmasta, käsitykset vammaisuudesta ja vammaisena olemisesta näyttäytyvät selvästi sukupuolittuneina. Tosin san…
Plasma Functionalization of Multiwalled Carbon Nanotubes and Their Use in the Preparation of Nylon 6-Based Nanohybrids
2012
The possibility to obtain carbon nanotubes (CNT)/polyamide 6 composites with excellent mechanical properties in a simple, industrially scalable way is investigated. Commercial CNTs are treated by plasma while changing some key parameters (exposure time, plasma power, type of gas) in order to optimize the process and to achieve a sufficient degree of functionalization. The treated samples are characterized by Fourier transform infrared spectroscopy, Raman spectroscopy and X-ray photoelectron spectroscopy. The most interesting samples are selected to be used as reinforcing fillers, in different concentrations, in a polyamide 6 matrix. The mechanical tests show a dramatic increase of both tens…
Biocompatible Lipid Nanoparticles as Carriers to Improve Curcumin Efficacy in Ovarian Cancer Treatment
2017
Curcumin is a natural molecule with proved anticancer efficacy on several human cancer cell lines. However, its clinical application has been limited due to its poor bioavailability. Nanocarrier-based drug delivery approaches could make curcumin dispersible in aqueous media, thus overtaking the limits of its low solubility. The aim of this study was to increase the bioavailability and the antitumoral activity of curcumin, by entrapping it into nanostructured lipid carriers (NLCs). For this purpose here we describe the preparation and characterization of three kinds of curcumin-loaded NLCs. The nanosystems allowed the achievement of a controlled release of curcumin, the amounts of curcumin r…
Elemental and microbiota content in indoor and outdoor air using recuperation unit filters
2021
Detection and quantification of engineered nanomaterials in environmental systems require precise knowledge of the elemental composition, association, and ratios in homologous natural nanomaterials (NNMs). Here, we characterized soil NNMs at the single particle level using single particle-inductively coupled plasma-time of flight-mass spectrometer (SP-ICP-TOF-MS) in order to identify the elemental purity, composition, associations, and ratios within NNMs. Elements naturally present as a major constituent in NNMs such as Ti, and Fe occurred predominantly as pure/single metals, whereas elements naturally present at trace levels in NNMs occurred predominantly as impure/multi-metal NNMs such as…
Neatņemamās daļas tiesīgo atstumšana no mantojuma
2022
Bakalaura darba mērķis ir analizēt neatņemamās daļas tiesīgo atstumšanas no mantojuma tiesisko regulējumu un vērtēt tā nepieciešamību mūsdienās Latvijas Republikas Civillikuma Mantojuma tiesību daļā. Attiecīgais tiesību institūts ir novecojis un neatbilstošs mūsdienu sabiedriskajai apziņai un valsts tiesiskajai iekārtai. Darbā tiek pētīta un analizēta neatņemamās daļas un neatņemamās daļas tiesīgo atstumšanas no mantojuma tiesību institūtu izcelsme un attīstība, kā arī sīkāk analizēti CL 427., 428., 429. un 431. pants. Darba gaitā tiek pamatota neatņemamās daļas un neatņemamās daļas tiesīgo atstumšanas no mantojuma tiesību institūtu izslēgšanas no CL nepieciešamība, paredzot jaunu tiesisko …
Neck–Shoulder Region Training for Chronic Headache in Women: A Randomized Controlled Trial
2023
Objectives We investigated whether a specific exercise program for the neck–shoulder region reduces headache intensity, frequency, and duration, and how it influences neck disability among women with chronic headache compared to a control group. Design Two-center randomized controlled trial. Subjects 116 working-age women. Intervention The exercise group (n = 57) performed a home-based program with six progressive exercise modules, over 6 months. The control group (n = 59) underwent six placebo-dosed transcutaneous electrical nerve stimulation sessions. Both groups performed stretching exercises. Main measures The primary outcome was pain intensity of headache, assessed using the Numeric Pa…
Neoliberal Governmentality and Knowledge Production in Higher Education: Genealogy of a Subjective Configuration
2015
En este artículo, se parte de la consideración de que cualquier interrogación sobre las condiciones de posibilidad de una investigación crítica debe hacerse teniendo en cuenta el proceso de mercantilización del conocimiento, impulsado por la incorporación de los modos de gubernamentalidad neoliberal en la universidad. Proceso este que redefine el valor y el uso que se le da al conocimiento producido y redefine también las subjetividades de los colectivos universitarios: formas de entender el conocimiento y configuraciones subjetivas que promueven modos instrumentales de relacionarse con el conocimiento en un escenario individualizador y competitivo. Por ello, se considera políticamente rele…
Benefits and drawbacks of communication visibility : from vicarious learning and supplemental work to knowledge reuse and overload
2022
Purpose This study aims to examine some of the benefits and drawbacks of communication visibility. Specifically, building on communication visibility theory, the authors study how and why message transparency and network translucence may increase knowledge reuse and perceived overload through behavioral responses of vicarious learning and technology-assisted supplemental work. Design/methodology/approach Drawing on survey data obtained from 1,127 employees of a global company operating in the industrial machinery sector, the authors used structural equation modeling to test the hypothesized model. Findings The results demonstrate that the two aspects of communication visibility yield somew…
A critical re-examination of the academic literature on venture capital networks
2020
This paper proposes a critical re-examination of the recent trends of the literature on venture capital networks. This brief review thoroughly scrutinises three papers that are representative of the recent academic literature in this field of study. I identify their points of strength and limitations, in order to pave the way for future research. This paper shows that the study of network weak and informal ties and the role of risk management strategies are promising areas for pushing the frontiers of research on venture capital networks. Extending our knowledge on this topic is crucial to understand the best strategic decisions venture capital firms should take, as parts of an inter-organi…
