School, boredoom and rebelliouseness
2002
This article intends to put light on some of the rationalization mechanisms of the boring and of the scholar disobedience presents at the modern psicopedagogical rationality. We carry on with this task spacing us out from a double position: the one that pathologies what challenge someone or defer from the established identities, and the one that turns violence into a simple phenomena of technical management and of production of expert wisdom. In order to rethink both scholar policy and psicopedagogical practices we will go deep on two phenomena by treating them as problematics. One of them is the 'institutional experience of going to the school'. The second one is inseparable from the above…
School leadership challenges in the implementation of technical and vocational education curriculum in Ghana
2015
Osei-Asibey Daniel. 2015. School Leadership challenges in the Implementation of Technical and Vocational Education Curriculum in Ghana. University of Jyvaskyla. Department of Education. ABSTRACT The purpose of technical and vocational education and training is basically to provide individuals with needed skills for socio-economic and industrial development. In most developing countries especially, TVET lays much emphasis on the kind of training that prepares the youth for self-employment. In Ghana like most developing countries, the aim of TVET is no different from the above. However, TVET in Ghana is bedeviled with a number of challenges ranging from limited funding, inadequate tools and e…
Effects of Onshore and Offshore Environmental Parameters on the Leading Edge Erosion of Wind Turbine Blades: A Comparative Study
2021
Abstract The presence of rain-induced leading edge erosion of wind turbine blades (WTBs) necessitates the development of erosion models. One of the essential parameters for erosion modeling is the relative impact velocity between rain droplets and the rotating blade. Based on this parameter, the erosion damage rate of a WTB is calculated to estimate the expected leading edge lifetime. The environmental conditions that govern this parameter have site-specific variations, and thus, rain and wind loading on a turbine differ for onshore and offshore locations. In addition, there are wave loads present in the offshore environment. The present paper tries to provide guidelines for erosion modelin…
Two-Leg Squat Jumps in Water: An Effective Alternative to Dry Land Jumps
2009
The current study was designed to quantify and compare the kinetic parameters of two-leg squat jumps carried out on dry land, in water and in water using area devices that increase drag force. Twelve junior female handball players who had been competing at national level for the previous two years volunteered to participate in the study. Intensity of the two-leg squat jump was examined using a force plate (9 253-B11, Kistler Instrument AG, Winterthur, Switzerland) in three different conditions: on dry land, in water and in water using devices. An ANOVA with repeated measurements (condition) was applied to establish differences between the three jumps. The results show that peak impact force…
Precipitation responses to ENSO and IOD in the Maldives: Implications of large-scale modes of climate variability in weather-related preparedness
2020
Abstract This research seeks to address the extent to which indices of large-scale modes of climate variability (El Nino Southern Oscillation (ENSO) and Indian Ocean Dipole (IOD)) can be linked to physical differences in the local mean and extreme rainfall conditions experienced in the Maldives in order to suggest implications for disaster risk reduction (DRR). While some significant differences in precipitation metrics do occur at the local level between different phases of the large-scale modes of climate variability studied, they do not occur for all sites studied. While the constrained availability of historical meteorological data in the region is a limiting factor in this analysis, th…
Boudinage classification: end-member boudin types and modified boudin structures
2004
In monoclinic shear zones, there are only three ways a layer can be boudinaged, leading to three kinematic classes of boudinage. These are (1) symmetrically without slip on the inter-boudin surface (no-slip boudinage), and two classes with asymmetrical slip on the inter-boudin surface: slip being either (2) synthetic (S-slip boudinage) or (3) antithetic (A-slip boudinage) with respect to bulk shear sense. In S-slip boudinage, the boudins rotate antithetically, and in antithetic slip boudinage they rotate synthetically with respect to shear sense. We have investigated the geometry of 2100 natural boudins from a wide variety of geological contexts worldwide. Five end-member boudin block geome…
Representation and videography in linguistic landscape studies
2017
AbstractMuch Linguistic Landscape scholarship relies on visual data collection, primarily the use of still photography; however, the field has yet to address the theoretical underpinning of such visual and spatial representation. Furthermore, digital video is currently as easy to capture and share as digital photographs were when Linguistic Landscape studies first became prominent in the early 2000s. With these two points in mind, this article first grounds the documentation and analysis of the Linguistic Landscape in a theory of visual representation; it then provides a framework for videographic methodologies drawing on recent work in the related fields of anthropology and cultural geogra…
Influence of column shear failure on pushover based assessment of masonry infilled reinforced concrete framed structures: A case study
2017
Structural frames, constructed either of steel or reinforced concrete (RC), are often infilled with masonry panels. However, during the analysis of the structural frames, it has become common practice to disregard the existence of infills because of the complexity in modeling. This omission should not be allowed because the two contributions (of infills and of frames) complement each other in providing a so different structural system. The use of different modeling assumptions significantly affects the capacity as well as the inelastic demand and safety assessment. In specific, the adoption of equivalent diagonal pin-jointed struts leaves open the problem of the evaluation of the additional…
ADV measurements of velocity distributions in a gravel-bed flume
2003
Velocity measurements carried out by an acoustic doppler velocimeter (ADV) in a rectangular laboratory flume having a gravel bed are presented. The velocity profiles are measured in six verticals of the channel cross-section having an increasing distance (from 4 to 38.5 cm) from the flume wall. The experimental runs are carried out for five different bed arrangements, characterized by different concentrations of coarser elements, and for the two conditions of small- and large-scale roughness. For both hydraulic conditions, the velocity measurements are first used to test the applicability of the Dean profile and of the logarithmic profile corrected by a divergence function proposed in this …
Non linear and linearized combination coefficients for modal pushover analysis
2017
Current design practice and seismic codes tend to assess seismic demand of buildings by Non linear Static Analysis (NSA), based on the evaluation of the pushover curve. Earlier non-linear static analysis procedure estimate the response peak value by evaluating the push-over curve adopting a distribution of invariant forces proportional to the fundamental vibration mode. In order to include the effect of higher modes several multimodal push-over analysis procedures were proposed in literature. In In the most famous of these, namely Modal Pushover Analysis (MPA), nodal response peak values are obtained by combination of "modal" responses by the traditional SRSS or CQC methods: the use of the …
