Social media e pubblica amministrazione. Una rassegna
2015
Negli ultimi vent’anni i processi di cambiamento strutturale a cui sono state indotte – o, in altri casi, a cui si sono strategicamente dedicate - le organizzazioni sono stati molteplici. Cause fra le più diverse hanno determinato, più o meno direttamente, effet-ti di ricombinazione delle funzioni interne alle stesse organizzazioni da parte degli atto-ri che le popolano, ovvero di una vera e propria nuova strutturazione, in ragione di mutate caratteristiche dell’ambiente in cui esse operano, di mutati e più stringenti vin-coli economici dentro i quali muoversi rispetto al passato anche recente e, nel caso di quelle che producono beni o servizi direttamente destinati ad una clientela o ad un…
Lyties dimensija socialiniame versle: Lietuvos socialinių verslininkių patirtys
2017
Straipsnyje nagrinėjama, kaip moterys – socialinės verslininkės – suvokia socialinį verslą ir lyties dedamąją tokiame versle. Interviu (n=18) su socialinių verslų Lietuvoje atstovėmis analizė parodė, kad socialinio verslo misija yra arba labai pragmatiška (organizacijų, turinčių socialinės įmonės juridinį statusą), atsiejama nuo socialinio poveikio, kurį tokie verslai paprastai kuria, arba gana neapibrėžta, tačiau akcentuojanti gėrio kūrimą. Tačiau į lyties dedamąją socialiniuose versluose žvelgiama stereotipiškai, t. y. lyties poveikis arba ignoruojamas, arba interpretuojamas stereotipiškai skirstant į tradiciškai laikomas vyriškomis ir moteriškomis veiklos sritis. This paper explores how …
Innovativeness and sustainable innovations in social businesses in Lithuania: experiences of women social entrepreneurs
2017
Straipsnyje nagrinėjamos socialinių verslininkių sampratos apie jų verslo novatoriškumo formas ir darniąsias inovacijas. Empirinis šio straipsnio pagrindas – interviu (n=18) su socialinių verslų Lietuvoje atstovėmis. Interviu medžiagos analizė parodė, kad moterys – socialinės verslininkės novatoriškumą bei darniąsias inovacijas tokio verslo kontekste apibrėžia tiek individo, tiek organizacijos lygmenimis, tačiau darniąsias inovacijas sieja su globaliais kontekstais ir technologijomis. Tokios sampratos atitinka kitose šalyse atliktų tyrimų rezultatus ir rodo analizuojamos tematikos universalumą, kita vertus – pagrindžia Lietuvoje atlikto tyrimo rezultatus. This paper focuses on the perceptio…
Combustion behavior of kraft black liquor droplets from hot water pretreated hardwood and softwood chips
2016
This paper describes the combustion behavior of birch and spruce kraft black liquors obtained from an integrated forest biorefinery concept in which a hot water extraction of chips was performed before pulping. This pretreatment, aiming mainly at the recovery of various hemicellulose-derived materials, increased the concentrations of lignin and hydroxy acids in black liquors, compared with those in the reference black liquors without any process modification. On the other hand, the pretreatment decreased the concentrations of volatile acids and other organics (extractives and hemicellulose residues). Because of these characteristic changes, the total burning times (pyrolysis time plus char …
Shaded-Mask Filtering for Extended Depth-of-Field Microscopy
2013
This paper proposes a new spatial filtering approach for increasing the depth-of-field (DOF) of imaging systems, which is very useful for obtaining sharp images for a wide range of axial positions of the object. Many different techniques have been reported to increase the depth of field. However the main advantage in our method is its simplicity, since we propose the use of purely absorbing beam-shaping elements, which allows a high focal depth with a minimum modification of the optical architecture. In the filter design, we have used the analogy between the axial behavior of a system with spherical aberration and the transverse impulse response of a 1D defocused system. This allowed us the…
WENO schemes applied to the quasi-relativistic Vlasov-Maxwell model for laser-plasma interaction
2014
Abstract In this paper we focus on WENO-based methods for the simulation of the 1D Quasi-Relativistic Vlasov–Maxwell (QRVM) model used to describe how a laser wave interacts with and heats a plasma by penetrating into it. We propose several non-oscillatory methods based on either Runge–Kutta (explicit) or Time-Splitting (implicit) time discretizations. We then show preliminary numerical experiments.
Two-dimensional filters for structured text
1997
The paper introduces a method for defining filters for structured text. In the method, the text structure is originally defined by a grammar consisting of a set of productions. To describe the information interests, a two-dimensional template is first created interactively from the grammar to show the structure of a set of textual elements, at a chosen level of detail. The template depicts the hierarchical structure of the elements and indicates also optionality, alternatives, and iteration in the structure. Then, the template is filled by constraints and annotations. The constraints allow giving conditions to the content of parts, to the position of parts in an ordered set of parts, and to…
Cross-technology wireless experimentation: Improving 802.11 and 802.15.4e coexistence
2016
In this demo we demonstrate the functionalities of a novel experimentation framework, called WiSHFUL, that facilitates the prototyping and experimental validation of innovative solutions for heterogeneous wireless networks, including cross-technology coordination mechanisms. The framework supports a clean separation between the definition of the logic for optimizing the behaviors of wireless devices and the underlying device capabilities, by means of a unifying platform-independent control interface and programming model. The use of the framework is demonstrated through two representative use cases, where medium access is coordinated between IEEE-802.11 and IEEE-802.15.4 networks.
