What do others think is the point of design and technology education?
As a result of a national curriculum review in England (Department for Education [DfE], 2011), a new curriculum for design and technology (D&T) is being taught in secondary schools from September 2014 (Department of Education [DoE], 2013a). This curriculum is compulsory for a decreasing number of schools; two potential consequences are the nature of D&T in secondary schools changing to reflect local perceptions of the subject and maybe D&T being removed from the curriculum completely. The pressure on D&Tâs curriculum content is likely to come from different stakeholders such as senior school leaders, D&T teachers, and pupils. D&T school departments could respond to this pressure by adapting the curriculum to popularise the subject or produce high exam results with a consequence that much of the subjectâs value is lost. This paper reports on a small research project conducted in two secondary schools where stakeholder representatives were interviewed to identify their values of D&T. These different stakeholders were interviewed using the active interview method (Holstein & Gubrium, 1995), coded following Aurebach and Silversteinâs method (2003) and their values compared to Hardyâs values framework (Hardy, 2013b). Analysis shows most stakeholders believe a key value of D&T is to provide âpractical life skillsâ (Hardy, p.226), whilst only one recognizes that learning in D&T involves âidentifying problems to be solvedâ. The outcomes from the research are being used to support critically reflective conversations within both D&T departments (Zwozdiak-Myers, 2012) framing their evaluation of their local curriculum and making changes to their curriculum
Relationship between Religion and Science: An Overview
This paper presents an overview of the relationship between religion and science. It points out that historically religion preceded science, as the limitations of human intelligence in a bizarre world led man very early to postulate a being considered ultimate, supreme and worthy of human obeisance and worship. Like religion and philosophy, science began in wonder: to explore the wonders of nature - of the physical world. Religion and science are related in that both of them have perspectives on cosmic reality, even though there are several differences in their interpretations of reality. It is the different interpretations as well as their methods at arriving at their truths and conclusions that eventuated in conflicts, conflicts that actually came to the fore with the emergence of experimental science in and after the seventeenth century of our era and led to the condemnation by the Catholic Church of Galileo, the acknowledged founder of modem science. Scientific theories such as the evolution theory, quantum physics, and some theories of neuroscience presented challenges to religious doctrines of creation, cosmic order and intelligibility, divine sovereignty, and human nature. However, there are areas of integration, such as natural theology and design, order and regularity of nature, that provide evidence of the existence of God- evidence that is supported by most scientists. The paper concludes that religion and science are different languages that ultimately express the same reality or at least present complementary accounts of reality, and that, given the wonders and mysteries of the created universe and the limitations of human intelligence, religion and science will continue to be bedfellows in the twenty first century and beyond
Patterns of Heavy Metals Contents in Urban Soils of Vasileostrovsky and Elagin Ostrov of Saint Petersburg, Russia
The study examined the total contents of heavy metals (TCHM) in urban soils of St Petersburg, Russia. Soils along areas of heavy traffic density, neighbourhoods or light industrial zones, residential areas, and recreational zones were sampled. The concentrations of cupper (Cu), lead (Pb). zinc (Zn) and manganese (Mn) in soils were significantly high -5-10 times above regional background levels. The concentration of Pb in soil samples varied from 0.6-110 mg/kg within the limits of Vasilesostrovvsky. and 0.3 -80 mg/kg in recreational zone of Elagin Ostrov, which is approximately 4 km away from Vaisileostrovsky. The presence of Cu was ubiquitous in all sampled soils and exhibited high contents ranging between 4.0-30 mg/kg. The contents of cadmium (Cd) in all tested soils were below regional background values indicating low emissions of that element from anthropogenic sources. Furthermore. the concentration of heavy metals in soils was related positively to areas of high traffic density, particularly to the central, eastern and south industrial areas or Vasilcostrovsky. Elagin Ostrov, generally, registered lower contents or total heavy metals and this might be attributed to its location and nature of land use. Appropriate land use and strategic management options that will help in reducing emissions and impacts of heavy metals in urban soils is recommended
Radiological Study of Radon Gas in Underground Goldmine
Indoor radon concentrations were collected monthly over a period of one year in 10 different levels in an underground goldmine to determine the radiological impact on workers. The detectors were installed in batches within four quarters. The measurements were carried out using LR115 solid state nuclear track detectors. The results show that the activity concentration of radon in the underground mine ranges from a minimum of 2 Bqm-3 to a maximum of 284 Bqm-3 with a mean value of 58.51 Bqm-3. The highest radon concentration was observed in the second quarter when the season was warm, and the lowest radon concentration was observed in the first quarter when the season was colder. The hazard indices, exposure rate, excess lung cancer risk and annual effective dose from the rock and soil samples possess no radiological hazard if used for building materials.

Knowledge and economic growth: a comparative analysis of three regional blocks in sub-Saharan Africa
African personhood, Humanism, and critical Sankofaism: the case of male suicide in Ghana
Suicide in Ghana is criminalised and those who survive suicide attempts are subject to significant social condemnation. Paradoxically, studies show that male suicide is often driven by individualsâ strong sense of responsibility to meet social norms and expectations around gender as well as the internalisation of societal views that death would be preferable to shame and disgrace. This contradiction prompts a critical re-examination of the communitarian tradition of African personhood which posits an intimate link between the individual attainment of socially affirmed roles and the status of personhood. Through an analysis of the Akan concept of critical sankofaism I suggest that African approaches to suicide may draw upon important adaptive, critical resources internal to African cultural values, thus highlighting the progressive potential of the African tradition. I show specifically how male gender norms and societal responses to suicide attempts distort core humanistic values at the heart of African communitarian personhood
Unsweetened Natural Cocoa Powder: A Potent Nutraceutical in Perspective
Unsweetened natural cocoa powder is a pulverized high-grade powder of compressed solid blocks which remains after extraction and removal of the cocoa butter. The authors determined the elementary composition of UNCP, investigated its effect on nitric oxide levels, toxicity, and its protective effect on the heart, kidney, and liver during simultaneous administration with high dose (HD) artemether/lumefantrine (A/L). Macro- and microelements in UNCP were analyzed with energy dispersive x-ray fluorescence spectroscopy (EDXRF). Adult male guinea pigs were administered various doses of UNCP alone and also simultaneously with A/L. Phytochemical analysis of UNCP showed the presence of saponins, flavonoids, tannins, cardiac glycosides, and 38 macro- and microelements. Histopathological analysis showed no toxic effect on the heart, liver, kidney, lungs, testis, and spleen. Administration of various doses of UNCP increased white blood cell counts and lymphocyte count (p > 0.05) compared with the controls. Additionally, UNCP and A/L combination caused an increase in nitric oxide levels when compared with the control group and restores some hematological disorders induced by the 3-day HD A/L administration. Even though UNCP appears to be relatively safe, care should be taken due to the high content of copper element to avoid the possibility of intestinal lining erosion
Long-term continuous administration of a hydro-ethanolic extract of Synedrella nodiflora (L) Gaertn in male Sprague-Dawley rats: biochemical, haematological and histopathological changes
Background: Conflicting reports about the toxicity of Synedrella nodiflora (L) Gaertn (family Asteraceae), a plant traditionally used in Ghana for the management of epilepsy, abound in literature. The present study evaluates the effect of a 90-day continuous oral administration of a hydro-ethanolic whole plant extract of Synedrella nodiflora (SNE) in male Sprague-Dawley rats.Methods: The toxicological evaluation of the extract (100, 300 and 1000 mgkg-1) was focused on haematological, serum biochemical parameters and histopathological changes of some isolated organs.Results: The extract produced no mortality in the rats treated during the study period. Only SNE 100 mgkg-1 produced significant decrease in white blood cell and neutrophil counts and an increase in albumin, globulin, total bilirubin, total protein and potassium levels. The higher doses (SNE 300 and 1000 mgkg-1) had no significant effect on all the haematological and biochemical parameters measured. Histopathological assessment of the liver, kidney and heart revealed no abnormalities in rats treated with the extracts. Only the SNE 1000 mgkg-1 produced distortions of the branching arrangements of the myocardial fibres and a congested vessel which indicates a healed infarction.Conclusions: The findings suggest hydro-ethanolic extract of Synedrella nodiflora (L) Gaertn generally has a low toxicity profile following a 90-day continuous oral administration in male Sprague-Dawley rats under the present laboratory conditions. However patients with renal or cardiac problems should use the plant with caution.Funding: Jointly supported by the International Foundation for Science, Stockholm, Sweden, through a grant (# F/5191-1) to Dr. Patrick Amoateng and the Office of Research, Innovation and Development (ORID), University of Ghana, Accra, Ghana, grant awarded to Dr. Patrick Amoateng (reference number: URF/6/ILG-002/2012-2013)Keywords: : Synedrella nodiflora, Sprague-Dawley rats, histopathological, haematologica
Security, Local Community, and the Democratic Political Culture in Africa
In this study, the idea of the local African community as a social structure ensuring the security of its members is presented. An understanding of the concept of security is first briefly discussed, followed by the meaning of the concept of the local African community. The chapter also makes an a priori distinction between what one can call âmoderateâ and âradicalâ types of communal life and two case studies exemplifying them are presented. The chapter aims to analyze the trade off, in terms of provision of security, including economic security, by local communities, for the shaping of a democratic political culture in Sub-Saharan Africa. Most importantly, however, this chapter also highlights the rationality that underpins the seemingly low-quality democratic political activities of members of local African communities
