Public Employees as Politicians: Evidence from Close Elections

2017

We analyze the effect of municipal employees’ political representation in municipal councils on local public spending. We use within-party, as-good-as-random variation in close elections in the Finnish open-list proportional election system to quantify the effect. One more councilor employed by the public sector increases spending by about 1%. The effect comes largely through the largest party and is specific to the employment sector of the municipal employee. The results are consistent with public employees having an information advantage over other politicians, and thus, being able to influence policy.

Cytokines and their effects on maturation, differentiation and migration of dendritic cells.

1996

In this review the role of cytokines in the maturation and migration of phenotypically and functionally diverse dendritic cell (DC) subpopulations is discussed and their role in the progress of differentiation from bone marrow progenitors to lymphoid DC is described. GM-CSF is the most important cytokine for the development of functional DC and acts in concert with a varying mixture of other cytokines such as IL-4, IL-1 and TNF-α to direct the development of individual DC subpopulations.

Dendritic cells (DC) are a heterogeneous family of professional antigen-presenting cells classically recognized as most potent inducers of adaptive immune responses. In this respect, Langerhans cells have long been considered to be prototypic immunogenic DC in the skin. More recently this view has considerably changed. The generation of in vivo cell ablation and lineage tracing models revealed the complexity of the skin DC network and, in particular, established the existence of a number of phenotypically distinct Langerin(+) and negative DC populations in the dermis. Moreover, by now we appreciate that DC also exert important regulatory functions and are required for the maintenance of tol…

Thyroid cartilage involvement in patient affected by IgA multiple myeloma: case report.

2008

Neoplasms originating from plasma cell are rare in the head and neck region. A correct clinical evaluation is very important in order to formulate a differential diagnosis as well as to distinguish local from metastatic disease. We report a case of larynx involvement by an IgA multiple myeloma in a 69-year-old female diagnosed in October 2004 and treated with chemotherapy; the 1 year control do not show progression of disease and the laryngeal lesion is unchanged. We highlight the radiological findings and clinical features to suspect plasma cell tumors in cases with a similar presentation.

Method to Define User Interfaces in the Requirements Analysis Phase

2018

Many requirements for quality in use are elicited in the late development phase. However, if requirements are elicited in the late development phase, the development may return to the previous phase or some requirements cannot be realized due to costs and schedules. To reduce these cases, we propose a method to elicit the requirements in the requirements analysis phase. First, software developers analyze the user characteristics (UCs) of the target users and specify important quality characteristics (QCs) for quality in use and UI design items based on the relationships among UC, QC, and UI design items. Because UI design items are considerations to develop UIs, the specified UI design item…

A Geometric Approach to Automatic Description of Iconic Scenes

2005

It is proposed a step towards the automatic description of scenes with a geometric approach. The scenes considered are composed by a set of elements that can be geometric forms or iconic representation of objects. Every icon is characterized by a set of attributes like shape, colour, position, orientation. Each scene is related to a set of sentences describing its content. The proposed approach builds a data driven vector semantic space where the scenes and the sentences are mapped. Sentences and scene with the same meaning are mapped in near vectors and distance criteria allow retrieving semantic relations.

Constructing the secular imagined community : a critical intercultural analysis of discourses of laïcité from Le Monde

2016

The concept of secularism encompasses numerous aspects beyond the regulation of relations between the State and Churches. Using a critical intercultural communication framework, this research project explores the interplay between secularism, culture, religion, identity, and collective representations. Specifically, this study focuses on laïcité, the concept of secularism used in France. Previous studies have criticized laïcité for being biased and contributing to inequalities between communities in France. The pervasive (and false) representation of laïcité as originally and exclusively French has also been criticized. In the light of the concerns raised by previous studies, this study set…

Explainable Reinforcement Learning with the Tsetlin Machine

2021

The Tsetlin Machine is a recent supervised machine learning algorithm that has obtained competitive results in several benchmarks, both in terms of accuracy and resource usage. It has been used for convolution, classification, and regression, producing interpretable rules. In this paper, we introduce the first framework for reinforcement learning based on the Tsetlin Machine. We combined the value iteration algorithm with the regression Tsetlin Machine, as the value function approximator, to investigate the feasibility of training the Tsetlin Machine through bootstrapping. Moreover, we document robustness and accuracy of learning on several instances of the grid-world problem.

Personalization of immediate feedback to learning styles

2007

Feedback provided to a user is an important part of learning and interaction in e-learning systems. In this paper we present the results of our pilot experiment aimed to study interrelation between several types of immediate feedback presentation and learning styles (LSs) of users. In the experiment we used the feedback supported by quiz module of moodle learning system. The obtained results demonstrate tendencies in interrelation between LS and immediate/summative feedback presentation and we suggest three hypotheses for future research.

Designing the Didactic Strategy Modeling Language (DSML) From PoN: An Activity Oriented EML Proposal

2018

[EN] This paper presents the design of the didactic strategy modeling language (DSML) according to the principles of Physics of Notations (PoN). The DSML is a visual and activity-oriented language for learning design characterized by the representation of different activities according to the nature of the task. Once the language is designed, a blind interpretation study is conducted to validate the semantic transparency of the learning activity iconography. The results of the paper allow to refine the icons. In addition to this, an authoring tool for DSML, which is integrated to an LMS, is presented. As a result, a model driven course was designed as a DSML pre-validation.
