A quantitative analysis of Educational Data through the Comparison between Hierarchical and Not-Hierarchical Clustering

2017

Many research papers have studied the problem of taking a set of data and separating it into subgroups through the methods of Cluster Analysis. However, the variables and parameters involved in Cluster Analysis have not always been outlined and criticized, especially in the field of Science Education. Moreover, in the field of Science Education, a comparison between two different Clustering methods is not discussed in the literature. Conceptions of students about modeling in physic are investigated by using an open-ended questionnaire. The questionnaire is analyzed through Clustering methods. The clustering results obtained by using the two methods are compared and show a good coherence bet…

Food labels: Do consumers perceive what semiotics want to convey?

2011

In this research work, a multidisciplinary approach was applied to answer the question: do consumers perceive what semiotics want to convey? The idea behind was to determine if consumers' expectations and associations raised by simulated yogurt labels, designed with different sign combinations frequently applied in commercial products, were in agreement with results from a semiotic analysis, and to check for cultural differences, comparing results from two Spanish-speaking countries (Spain and Uruguay).A survey of the plain yogurt market was performed, followed by a semiotic analysis of the gathered labels performed by a team of semiotics experts. Only the non-verbal elements such as images…

The logic of the gift and the bonding value: a new perspective for business management

2011

PurposeThis paper aims to conceptualize business relationships so as to include in these dimensions of both gift and gratuity, to develop the concept of “bonding value”, and to offer some ideas for the use of this within firms.Design/methodology/approachThe paper analyses the concept of “bonding value”, distinguishing it from the concepts of “exchange value” and “use value” that are normally used in business, and attempts to investigate its practical implications.FindingsThe paper shows how evaluating both the relationships within the organization and between firm and stakeholders in terms of “bonding value” can have effects on the economic, organizational and social aspects of a firm's act…

E‐learning at work: theoretical underpinnings and pedagogical challenges

2005

PurposeFirst, to explore the application of e‐learning as a medium for workplace learning, as a form of adult learning and organisational learning from a theoretical point of view, second, to review empirical studies on recent solutions to pedagogical problems encountered in workplace learning in general and in e‐learning in particular, and finally, to consider the challenges facing the further development of e‐learning solutions targeted at the workplace.Design/methodology/approachThe paper reviews theories of adult learning, workplace learning and organisational learning and brings out main pedagogical implications of these theories from an e‐learning point of view. Some empirical studies…

Towards the column bed stabilization of columns in capillary electroendosmotic chromatography

2000

This article discusses a novel method generating a continuous bed inside the CEC column. The column bed composed of microparticulate reversed-phase silica is completely immobilized by a hydrothermal treatment using water for the immobilization process. This process eliminates the manufacture of frits of both ends of the column and all problems associated with their preparation. Fundamental studies on operational parameters will be presented such as the dependence of the immobilization on the column temperature, the type of stationary phase and the column back pressure. The immobilized CEC columns show the same high column efficiency as packed columns with frits.

Particle packed columns and monolithic columns in high-performance liquid chromatography-comparison and critical appraisal

2007

The review highlights the fundamentals and the most prominent achievements in the field of high-performance liquid chromatography (HPLC) column development over a period of nearly 50 years. After a short introduction on the structure and function of HPLC columns, the first part treats the major steps and processes in the manufacture of a particle packed column: synthesis and control of particle morphology, sizing and size analysis, packing procedures and performance characterization. The next section is devoted to three subjects, which reflect the recent development and the main future directions of packed columns: minimum particle size of packing, totally porous vs. core/shell particles an…

Half-width plots, a simple tool to predict peak shape, reveal column kinetics and characterise chromatographic columns in liquid chromatography: Stat…

2013

Peak profiles in chromatography are characterised by their height, position, width and asymmetry; the two latter depend on the values of the left and right peak half-widths. Simple correlations have been found between the peak half-widths and the retention times. The representation of such correlations has been called half-width plots. For isocratic elution, the plots are parabolic, although often, the parabolas can be approximated to straight-lines. The plots can be obtained with the half-widths/retention time data for a set of solutes experiencing the same kinetics, eluted with a mobile phase at fixed or varying composition. When the analysed solutes experience different resistance to mas…

Modifying the texture of foods for infants and young children

2015

The first section of this chapter describes the evolutions in oral physiology (anatomical motor components, oral motor skills and feeding skills) in healthy children (< 3 years). The second section describes how each type of texture is accepted at each oral physiology stage, and how exposures to textures impact oral physiology development and acceptability of textures. The third section shows how the need to modify food texture for infant foods is addressed, through national regulations or recommendations from public health bodies, and describes practices of texture modification, based on national surveys and case reports (including baby-led weaning). The chapter is closed by a commentary o…

Experience with the Hellp-Syndrohe

1988

A total of 13 patients with HELLP-Syndrome were treated between 1980 and 1986 at the Mainz University Gynecology Clinic. The course of disease, complications, and fetal outcome observed do not permit generalized recommendations concerning treatment of this syndrome. The treatment plan should rather be based on the Individual situation, whereby the cesarean section has proven to be the preferred mode of delivery in almost all cases.
