Informal learning in the workplace: A review of the literature

In the last few decades, the workplace has been increasingly recognised as a legitimate environment for learning new skills and knowledge, which in turn enables workers to participate more effectively in ever-changing work environments. Within theworkplace, there is the potential for continuous learning to occur not only through formal learning initiatives that are associated with training, but also through informal learning opportunities that are embedded within everyday work activities. This paper surveys the growing body of literature on informal learning, makes some critical observations about the importance of informal learning, and explains the various ways that informal learning can occur in the workplace

Radiation-cooled Dew Water Condensers Studied by Computational Fluid Dynamic (CFD)

Harvesting condensed atmospheric vapour as dew water can be an alternative or complementary potable water resource in specific arid or insular areas. Such radiation-cooled condensing devices use already existing flat surfaces (roofs) or innovative structures with more complex shapes to enhance the dew yield. The Computational Fluid Dynamic - CFD - software PHOENICS has been programmed and applied to such radiation cooled condensers. For this purpose, the sky radiation is previously integrated and averaged for each structure. The radiative balance is then included in the CFD simulation tool to compare the efficiency of the different structures under various meteorological parameters, for complex or simple shapes and at various scales. It has been used to precise different structures before construction. (1) a 7.32 m^2 funnel shape was studied; a 30 degree tilted angle (60 degree cone half-angle) was computed to be the best compromise for funnel cooling. Compared to a 1 m^2 flat condenser, the cooling efficiency was expected to be improved by 40%. Seventeen months measurements in outdoor tests presented a 138 % increased dew yield as compared to the 1 m^2 flat condenser. (2) The simulation results for 5 various condenser shapes were also compared with experimental measurement on corresponding pilots systems: 0.16 m^2 flat planar condenser, 1 m^2 and 30 degree tilted planar condenser, 30 m^2 and 30 degree tilted planar condenser, 255 m^2 multi ridges, a preliminary construction of a large scale dew plant being implemented in the Kutch area (Gujarat, India)

Small business owners: too busy to train?

Purpose – The reason often cited for the poor relationship between small businesses and their uptake of vocational education and training is that small business owner-managers claim that they are too busy to engage in training or any type of learning activity and that most training is of little value to them. The aim of the research is to examine the relationship between these factors. Design/methodology/approach – Using qualitative research methods the study collected data of the knowledge, attitudes and needs of small business owner-managers, both before and after participation in a training program. Findings – This study has indicated that small business owners are interested in skills development and training opportunities, provided that they are directly applicable to the current situation in their business, and as long as the delivery process is carefully structured in terms of location, time of day, and length of session. Practical implications – The success of a human resource management training program offers both an incentive for other educators to continue to pursue small business participation and useful guidelines for the implementation and the development of new programs for the small business sector. Originality/value – The approach taken in this research has offered important insights into the value of training and how it is evaluated by small business owner-managers. This is important as owner managers are the primary decision makers about whether or not training takes place

The Development of a Student Focused Model for Transition to University

The transition to university is a well recognised challenge, especially for non-traditional students. This paper presents a student-focused model for the transition to university, developed through an extensive literature review, discussions with a range of professionals nationally and internationally, and first year teaching practice. The model was applied to the development of a range of strategies to be implemented at one institution. The use of the model may facilitate the development of a university-wide approach to the issues of student transition to university and the first year in higher education experience. The model will allow a balanced approach to be developed

Fog and Dew Collection Projects in Croatia

The present paper discusses the fog and dew water collection in Croatia. Zavizan, the highest meteorological station in Croatia(1594m) is chosen for collecting of fog water with a standard fog collector (SFC). The highest daily collection rate was 27.8 L / m2. The highest daily collection rate in days without rain was 19.1 l/m2. Dew is also a noticeable source of water, especially during the drier summer season. Dew condensers in Croatia have been installed on the Adriatic coast (Zadar) and islands Vis and Bisevo. We report and discuss the data collected since 2003. In the small Bisevo island, a special roof has been designed to improve the formation and collection of dew on a house. Data from April 2005 will be presented and discussed.Comment: accessible sur http://balwois.mpl.ird.fr/balwois/administration/full_paper/ffp-587.pd

Seasonal and interannual variability in wind field and commercial catch rates of austroglossus pectoralis (soleidae)

The impact of deviations in the direction and strength of the wind field on the spatial, seasonal and interannual variability in catch rates of Agulhas sole Austroglossus pectoralis was investigated. Temporal variabilityin the wind cycle on the Agulhas Bank during the period 1981–1996 was deduced mainly from trends in the pressure gradient, measured from south of Cape Agulhas (35°S) to the region of westwind drift (40°S).Because interannual deviations in the catch rates differed between seasons, catch rates were assessed by season. Coastal catch rates of Agulhas sole between Cape Agulhas and Cape Infanta were high in autumn and winter, when offshore north-westerly winds prevailed, and low in spring and late summer, when onshore south-easterly winds dominated. There was often a secondary peak in catch rates in November–December,coincident with a midsummer change in the pressure gradient. Between the period 1982 and 1996, catch rates in autumn and early winter (April–July) were highest during years when the winter north-westerly winds were strongest (r2 = 0.62, p < 0.01). Catch rates usually peaked in May–June. This pattern changed in some years, depending on the timing and rate of change to winter wind conditions. Seasonal and interannual fluctuations in catch rate are associated with deviations in the wind field, but the  mechanism whereby this  effect is mediated remains unknown

Is there a link between BRIC foreign direct investment and SADC export performance?

The BRICS (Brazil, Russia, India, China and South Africa) countries have agreed to strengthen their economic ties, thus paving the way for enhanced trade and investment performance. South Africa’s strategic value in BRICS is that it is a gateway to the opportunity-rich Southern African Development Community (SADC). By using South Africa as a production hub for exports to the surrounding region, foreign investors would have ready access to neighbouring markets. This article addresses the question of whether, and in what ways, foreign direct investment (FDI) from the BRIC (Brazil, Russia, India and China) countries to the SADC influences the SADC’s export performance. A series of empirical analyses revealed a positive causation between BRIC FDI and SADC exports, offering a clear incentive for the SADC to rejuvenate its trade and investment policies and structures, and strengthen its ties with BRIC countries in the interests of attracting more FDI and building a strong and sustainable export sector.http://www.tandfonline.com/loi/cdsa202017-01-31hb201

A citizen-centred approach to education in the smart city: incidental language learning for supporting the inclusion of recent migrants

Smart cities are often developed in a top-down approach and designers may see citizens as bits within data flows. A more human-centred perspective would be to consider what the smart city might afford its citizens. A high speed, pervasive network infrastructure offers the opportunity for ubiquitous mobile learning to become a reality. The MASELTOV project sees the smart city as enabling technology enhanced incidental learning: unplanned or unintentional learning that takes place in everyday life, in any place, at any time, with the city itself the context and the prompt for learning episodes. Migrants in particular will benefit: limited in their opportunity to attend formal education yet with a pressing need for language learning to support their integration. Incidental learning services, like smart city planning, need interdisciplinary communication for successful development. We describe the MASELTOV Incidental Learning Framework which will act as a boundary object to facilitate this process.

Informal learning in the workplace: Approaches to learning and perceptions of the context

Questionnaires have been devised to investigate informal learning in the workplace based on an analogy with approaches to studying in higher education. This chapter focuses attention on issues of theory by critically evaluating different models of the relationship between employees’ approaches to workplace learning and their perceptions of the workplace context. In addition, this chapter focuses attention on issues of method by critically evaluating two particular instruments that have been devised in order to measure employees’ approaches to workplace learning and their perceptions of the workplace context. We use data from an online survey in which the Approaches to Work Questionnaire and the Workplace Climate Questionnaire were administered to employees who were taking courses by distance learning with the UK Open University. Factor analyses confirmed that both questionnaires measured three distinct scales. Canonical correlation analysis showed that the employees’ scores on the two instruments shared 43% of their variance. Path analysis found evidence that variations in approaches to learning lead to variations in perceptions of the workplace climate but not for the converse relationship
