Post-fotografia etnografica

2021

È evidente come la nostra società tecnologica sia legata senza alcun dubbio alla diffusione delle immagini. Autori come Gottfried Boehm, John Mitchell, Hans Belting hanno indagato la natura dell'immagine ponendo le basi, negli anni Novanta, per l'idea di un pictorial turn, di una cultura totalmente dominata dalle immagini che è diventata adesso una possibilità tecnica reale su scala globale. Un nuovo statuto dell'immagine che si usa raccogliere sotto l'etichetta di iconic turner inserito nel più vasto campo visual culture studies. L'uso del termine cultura accanto a quello di visuale è indicativo dell'ampiezza del campo d'indagine che visual culture studies si prefiggono di ricercare: essi …

Scour on Alluvial Bed Downstream of Grade-Control Structures

2004

This paper describes an approach for predicting local scour downstream of grade control structures. The developed analysis applies the incomplete self-similarity (ISS) theory for deducing some physically based dimensionless groups controlling the geometrical pattern of the scour profile. The scour measurements available in the literature in conjunction with numerous unpublished data allow a multiregressive calibration of the ISS relationships. The experimental sample includes different bed grain-size distributions and scales of the erosive phenomenon. The results prove that the ratio between the upstream water head and the weir height is able to explain the measurements of scour depth carri…

Response spectrum analysis of frame structures: reliability-based comparison between complete quadratic combination and damping-adjusted combination

2019

In the framework of seismic design of structures, response spectrum analysis (RSA) is the most commonly used approach in practice. The most popular combination rule is the complete quadratic combination (CQC) which is also prescribed by the most of seismic design codes and is based on the assumptions that the seismic acceleration is a white noise process and the peak factor ratios associated to the total and modal responses are unitary. Recently, the damping adjusted combination (DAC) rule has been developed for base-isolated structures to overcome the aforementioned simplified assumptions. Although it has been proved that the simplifications about peak factors lead to noticeable errors in …

Policy-practice gap in participation of students with disabilities in Ethiopia's formal vocational education programme

2017

In Ethiopia, individuals with disabilities have limited access to educational and vocational training opportunities due to environmental, attitudinal and institutional barriers. The overarching purpose of the study was to investigate the status of inclusiveness of relevant policy and legal instruments of the study countries and their practicality in vocational education programmes. The specific aims of the study were to: explore the extent to which the issue of special educational and training needs for persons with disabilities is addressed in the education and training policy of Ethiopia, specifically focusing on technical and vocational education and training (TVET); investigate prevaili…

On the use of information systems research methods in data mining

2006

Information systems are powerful instruments for organizational problem solving through formal information processing (Lyytinen, 1987). Data mining (DM) and knowledge discovery are intelligent tools that help to accumulate and process data and make use of it (Fayyad, 1996). Data mining bridges many technical areas, including databases, statistics, machine learning, and human-computer interaction. The set of data mining processes used to extract and verify patterns in data is the core of the knowledge discovery process. Numerous data mining techniques have recently been developed to extract knowledge from large databases. The area of data mining is historically more related to AI (Artificial…

Human and organizational factors in European nuclear safety: A fifty-year perspective on insights, implementations, and ways forward

2022

Abstract In this essay we investigate the “lessons learned” within the domain of human and organizational factors (HOF) from operating European nuclear power plants (NPPs) in a fifty-year perspective. Specifically, we consider learning processes at an industry level that aim at promoting human contributions to nuclear safety. This is done by bringing together two main perspectives: (1) a historical perspective on HOF-related institutional and research initiatives is presented by outlining the history of nuclear safety according to three major nuclear accidents, (2) an applied perspective is provided on how HOF are managed in the field. This latter perspective rests on the results of the EU …

Socio-technical innovation in community-based tourism organizations: A proposal for local development

2021

Abstract Socio-technical innovation is based on new patterns of interaction involving a set of new behaviors that have been legitimized in a given context. The approach of socio-technical innovation complements a purely technological innovation focus. However, studies of how to address social and environmental challenges under this approach are scarce. The aim of this paper is to identify the technical and social structures that underpin the socio-technical innovation system of community-based tourism organizations (CBTOs). This paper offers an in-depth case study of a specific type of collective property known as an “ejido”. Through this case study, the paper highlights the aspects that ha…

Diffusion Models in Analysing Emerging Technology-based Services

2005

In this article we discuss the problems of utilizing innovation diffusion (or, adoption) models in developing scenarios for mobile commerce services in three European countries: Finland, Germany, and Greece. We are not to test the various diffusion models as such, but rather to utilise the fundamental ideas of the models in determining the prerequisites for, the status of, and the pace of diffusion of mobile services in these different market areas. The estimates would serve as a starting point and as a validity check for scenario development. The early experience at the research design phase show that the ‘mainstream’ diffusion approach is vulnerable to three factors specific to the adopti…

Knowledge Representation in Travelling Texts:from Mirroring to Missing the Point

2014

<p><em>Today, information travels fast. Texts travel, too. In a corporate context, the question is how to manage which knowledge elements should travel to a new language area or market and in which form? The decision to let knowledge elements travel or not travel highly depends on the limitation and the purpose of the text in a new context as well as on predefined parameters for text travel. For texts used in marketing and in technology, the question is whether culture-bound knowledge elements should be domesticated or kept as foreign elements, or should be mirrored or moulded—or should not travel at all! When should semantic and pragmatic elements in a text be replaced and by w…
