Asante Bekwai United Schools’ Arts and Crafts Centre: a Model of Technical/Vocational Education (TVE) Curriculum Diversification and Utilization of local Expertise in colonial Ghana (1940-1950)

The paper discusses the general organization and operation of Asante Bekwai United Schools’ Arts and Crafts Centre as a model of TVE in the country during the 1940s. In particular, it focuses, inter alia, on the positive consequences of judiciously utilizing the “top-down change” and “bottom-up change” to use the words of Fullan (2007) in TVE educational policy formulation and implementation in colonial Ghana. This feat was achieved through the leadership efforts of the British colonial administration, the four missionary bodies then at Asante Bekwai (namely the Methodist Mission, the English Church Mission, the Catholic Mission and the Seventh-day Adventist Mission) the Asante Bekwai traditional authority and the Achimota College in Accra. It further discusses the nature of the curriculum of the Centre and its utilization of local expertise in the teaching and learning process It further discusses the effects of the income generation activities at the Centre. In this endeavour, a critical analysis of relevant historical information retrieved from the Public Record and Archives Department (PRAAD) office in Asante Region of Ghana was undertaken by the authors. The study, inter alia, revealed that the collaboration between the Centre and stakeholders greatly contributed to the steady progress of the Centre. It was again observed that the curriculum of the Centre was quite versatile; capable of equipping its beneficiaries to acquire relevant skills for productive livelihoods. The vibrant nature of the Centre was also evident by the fact that the income that was generated from the activities was used to procure some tools for the Centre. Undoubtedly, such an educational initiative was bound to grapple with teething challenges and it was anticipated that such challenges would be quickly addressed for smooth progress of the Centre. Future studies into such challenges and their remedies are thus encouraged. Keywords: Asante Bekwai; Arts and Crafts; mat weaving; pottery, curriculum, Achimota
Studies of epigenetic mechanisms affecting transcription in "Arabidopsis thaliana"

Le gene MOM1 code une proteine de 2001 acides amines qui ne presente d'homologie avec les sequences disponibles dans les bases de donnees qu'au niveau d'une region de 300 acides amine, reliquat d'un domaine SNF2. La mutation mom1 entraine la reactivation transcriptionnelle de transgenes et de loci endogenes silences. Mes etudes ont permis de montrer que l'activite de MOM1 porte non seulement sur les transposons mais egalement sur des genes impliques dans le developpement. MOM1 ne possede d'homologues que parmi les plantes vasculaires, ceux-ci partageant quatre motifs appeles CMM1-4. Un seul motif neanmoins (CMM3) est indispensable a la fonction de MOM1, la sequence de MOM1 pouvant etre reduite de 87% sans affecter sa fonction. Cette partie de la proteine qui n'est pas impliquee dans le silencing transcriptionnel pourrait jouer un role dans une fonction encore inconnue de MOM1.
Developing an Ionospheric Scintillation Monitoring Receiver

S E P T E M B E R / O C T O B E R 2 0 1 4 www.insidegnss. com Severe signal amplitude and phase scintillation induced by ionospheric activity can pose significant challenges to most commercial receivers and can degrade ranging accuracy, cause carrier-phase cycle slips, and even induce loss of lock on some satellites. The difficulties that receivers experience in tracking GNSS signals during such ionospheric activity directly translate to a difficulty in measuring this same activity. Ionospheric scintillation typically has adverse effects at the synchronization and tracking stage of a GNSS receiver and, therefore, is a threat to all navigation receivers incorporating GNSS technology, including stand-alone, differential, assisted, and inertial-coupled receivers. As such, monitoring the ionosphere via GNSS signals is an important task, both to understand space weather and the atmosphere and to understand its effects on GNSS receiver operation and performance. GNSS-based studies of the ionosphere are typically conducted using precision navigation receivers that track both the carrier and code phase, either on a satellite-by-satellite basis or collectively by means of a vector structure. Information relating to phase and amplitude scintillation is gathered from the receiver’s estimate of the carrier phase and the receiver correlators values, respectively. The quality of these parameters, however, is directly influenced by how well the receiver can track the GNSS signals. Under scinti l lat ion conditions these measurements are corrupted and degraded as the errors in the code and carrier tracking loops grow. Codephase biases will manifest themselves as amplitude fades and carrier phase cycle-slips will appear as large, sudden phase fluctuations. Given such corrupted data, it can be difficult to distinguish between receiver-induced artifacts and ionosphere anomalies. Moreover, if a receiver cannot acquire or track the signal, these measurements are simply not available. To tackle this problem, some receiver companies have produced variations of their precision receivers and postprocessing software, which have been specifically configured and tuned to increase robustness under high ionospheric activity. These improvements are primarily in the area of baseband configuration, such as phase-lock loop A team of researchers describes the development of a custom system for monitoring and collecting data on ionospheric scintillation and reports on its performance at facilities in the equatorial and arctic regions.
THE EVOLUTION OF VERTEBRAL PNEUMATICITY IN SAUROPOD DINOSAURS

Abstract The vertebrae of sauropod dinosaurs are characterized by complex architecture involving laminae, fossae, and internal chambers of various shapes and sizes. These structures are interpreted as osteological correlates of an intricate system of air sacs and pneumatic diverticula similar to that of birds. In basal sauropods pneumatic features are limited to fossae. Camerae and camellae are internalized pneumatic chambers independently acquired in neosauropods and some Chinese forms. The polycamerate and camellate vertebrae of higher neosauropods are characterized by internal pneumatic chambers of considerable complexity. The independent acquisition of these derived morphologies in Mamenchisaurus, derived diplodocids, and most titanosauriforms is correlated with increasing size and neck length. The presacral vertebrae of basal sauropods were probably pneumatized by diverticula of cervical air sacs similar to those of birds. Although pneumatic characters in sauropods are most extensive and complex in presacral vertebrae, the sacrum was also pneumatized in most neosauropods. Pneumatization of the proximal caudal vertebrae was achieved independently in diplodocids and titanosaurids. In birds, the synsacrum is pneumatized via abdominal air sacs which function primarily in lung ventilation. The presence of pneumatized sacral and caudal vertebrae in neosauropods indicates that abdominal air sacs were probably present in at least some sauropods.
IMPROVING TEACHER-STUDENT CONTACT IN A CAMPUS THROUGH A LOCATION-BASED MOBILE APPLICATION

This paper presents a new mobile micro-broadcast (or near-me) Location-Based Service designed to promote face-to-face communication among users located within a given geographical area such as a University campus. Because the communication services provided are time dependent, the application decides whom to contact based on the geographic distance between the active subscribers of the service and the sender. The paper also presents some preliminary results of prototype evaluation.
In search of corporate social responsibility: Introduction to special issue

This introduction to the special issue aims to contextualize and critically comment on the current trajectory of Corporate Social Responsibility (CSR) in both scholarly inquiry and business practice. It suggests that we must place it within the milieu of the ongoing economic crisis and the failure of a number of important opportunities to make business ethical (e.g. the 2012 Rio + 20 Earth Summit). It then suggests possible future terrain for tenable CSR research (and practice), especially in the context of widespread cynicism and disbelief regarding the claims of business ethicists in industry and the academy.
Cameroun. Le commerce transfrontalier informel des produits agricoles et horticoles

L’interet pour le commerce transfrontalier des produits agricoles et horticoles entre le Cameroun et ses voisins de la CEMAC est evident. Mais la connaissance de son ampleur, de ses determinants et de ses consequences reste insuffisante en raison de leur caractere informel car non prise en compte dans les statistiques officielles, ce qui handicape la formulation des politiques economiques appropriees et des strategies pour exploiter son impact potentiel sur la croissance et la reduction de la pauvrete. Le but de cet article vise a lever cette meconnaissance en estimant le volume et la valeur de ce commerce. Des recommandations de politique economique sont ensuite formulees pour une contribution de ce sous-secteur a l’economie de la sous- region en general et du Cameroun en particulier.
A Dual-Band Bandpass Filter Using SIR Suitable for WiMAX Band

In this paper a dual band bandpass filter with sharp rejection is proposed. The filter is realized by using two half wavelength stepped impedance resonator to operate at the passband 2.5 GHz and 3.5 GHz. To increase the band width further interdigital capacitors are introduced between resonator and input and output combining network. A finite transmission zero in between two pass band at 2.84 GHz is realized to improve the selectivity of the filter. The design procedure to get highly selective response of the proposed filter is explicitly explained. An equivalent circuit model of proposed filter is developed that matches well with full wave electromagnetic simulations.
A review of the metamorphism and classification of seasonal snow cover crystals

Knowledge of the growth of ice crystals In both wet and dry snow has evolved steadily over many years. Dry snow is characterized by rounded crystals growing slowly at low temperature gradients. Wet snow is characterized by clusters of grains at low liquid contents and poorly bonded slush at high liquid contents. Melt-freeze cycles greatly influence wet snow as well. Information was first gained through field observations, then laboratory tests, and then physical modeling. Advances have been made through application of phase-equilibrium thermodynamics and knowledge of ice crystal growth although much remains to be learned about the slow growth of ice crystals over a range of temperatures. The grain-to-grain nature of vapor flow in dry snow is complicated by the geometry of snow and this topic is being studied through stereology. Given recent advances in our understanding of snow metamorphism, a reclassification of snow seems necessary. "Une Revision de la Metamorphose des Cristaux de neige et de leur classification.

Selection of ocean container carriers: One countrys perspective

The objective of this study is to identify the most influential factors that affect choice of ocean container carrier by freight forwarders. It identifies the most influential factors considered by them when selecting ocean container carriers by analysing data collected from a survey of 105 freight forwarding organisations in Ghana. Exploratory factor analysis is used to identify the underlying factors which influence the selection of carrier. The findings of the study indicate that service quality, document accuracy, freight rates, environmental issues, schedule reliability and quick handling are the most influential factors that guide freight forwarders when purchasing liner shipping service. This study provides a better understanding of these influential factors from the perspective of the freight forwarders themselves. The findings are important to ocean container carriers since they can enable liner shipping companies to channel resources appropriately in response to factors which are identified as determining freight forwarder carrier selection. Key word: Freight forwarders, ocean container carriers, carrier selection factors.
The International Trends In Plant Variety Protection

This paper examines international trends in plant variety protection, a form of intellectual property rights for plant varieties akin to patents. The TRIPs Agreement under the WTO has given a strong impetus for the universalisation of plant variety protection regimes with common standards of protection across countries. This paper argues that developed and developing countries are likely to adopt widely divergent approaches to the development of intellectual property rights for plant varieties. The special features of plant variety protection constrain the appropriability of economic returns from protected plant varieties. Consequently, in developed countries PVP is being seen as a relatively weak intellectual property right instrument. As stronger forms of protection for plant varieties become available, the importance of plant variety protection in developed countries may decline. Developing countries continue to debate the merits of extending intellectual property rights to agriculture, though they too are obliged under the TRIPs Agreement to protect plant varieties. Their concerns are focused on the “inequities” inherent in a system of plant breeders’ rights. Attempts by developing countries to incorporate farmers’ rights provisions in their PVP systems are likely to dilute the incentives for private investment in plant breeding.
Diffusion of innovation: how the use of video games can increase the adoption of new technologies

This research examines the influence of videogames in the process of adoption of New Technologies in a sample of individuals from the Region of Murcia, Spain. For this, a quantitative methodology was used, which was based on a personal questionnaire, starting from the theory of Diffusion of Innovations by Everett Rogers. This theory allowed for the identification of the process of adoption of an innovation within a social group in a specific amount of time, identifying the channels through which the flow of information was produced. The behaviour patterns of videogame players and non-videogame players were compared in order to identify the differences and similarities between both groups. The results show the importance that people who play videogames have as drivers of the process of adoption of New Technologies in the social system where they belong to.
Matching Higher-Order Cognitive Skills (HOCS) promotion goals with problem-based laboratory practice in a freshman organic chemistry course

The development of students’ higher-order cognitive skills (HOCS) is central to the problem-based component of a freshman organic chemistry course. HOCS within science education is strongly connected to critical thinking (CT) and problem solving (PS), and often manifested by question asking and decision making. The laboratory, if utilized effectively, can be fertile ground for HOCS/PS development and CT advocacy. The ultimate goal is to develop a student culture having a broader, deeper, and more interconnected level of scientific literacy, conceptual understanding, and the contextual applications of knowledge. The concluding 6-hour laboratory session of the course ‘Introduction to Modern Organic Chemistry’ is presented here as an example of problem (not exercise) solving, and is proposed as a model for a ‘HOCS- promoting’—CT/PS-requiring laboratory activity in organic chemistry teaching.

Diurnal temperature cycle deduced from extreme daily temperatures and impact over a surface reanalysis system

Abstract. Due to the evolution of the observation network, hourly 2 m temperature analysis performed by reanalysis systems shows temporal inhomogeneities. The observation network gap is less present for extreme daily temperature observations. In order to reduce inhomogeneities and enable a climatological use of temperature analysis, information from extreme temperatures could be useful. In this study, the diurnal temperature cycle has been reconstructed for stations which only record extreme temperatures. These new "pseudo" hourly temperature observations are then provided to the analysis system. Two methods have been used to deduce hourly temperatures from extremes and compared to real observations. The results have shown that using those new pseudo-observations as an input for two different reanalysis systems enables reducing the bias in temperature analysis.

Carbon sequestration potential of nitrogen-fixing tree stands

Abstract We compared the C storage of two nitrogen-fixing trees in mixed and monospecific plantations to investigate the C sequestration potential after 10 years of their establishment. The study was carried out in three types of plantation, Dalbergia sissoo Roxb. ex DC. pure (P1DS), Leucaena leucocephala (Lam.) de Wit pure (P2LL) and mixed plantation of D. sissoo and L. leucocephala (P3DS.LL). The results of the study indicated that, P3DS.LL sequestered 34.30 ± 0.24 t yr-1 ha-1 CO2 compared to 27.35 ± 0.19 t yr-1 ha-1 in P1DS and 19.81 ± 0.44 t yr-1 ha-1 in P2LL. Total carbon storage was also maximum in P3DS.LL (93.47 ± 0.67 t ha-1) followed by P1DS (74.54 ± 0.53 t ha-1) and P2LL (53.98 ± 1.21 t ha-1). This indicates that L. leucocephala has synergetic effect with D. sissoo to enhance the carbon sequestration potential when interplanted together. The study revealed that mixed plantation of N-fixer trees have potential to sequester more carbon than same species in monoculture. The study concluded that in reforestation or afforestation program the synergic effect of N-fixer trees can be helpful projects to offset more C emissions.

Modeling Loss Given Default (LGD) by Finite Mixture Model

The loss given default or claim data, which tends to be skewed, heavy-tailed, multimodal, or kurtosis-likely, from the insurance and banking industry is routinely fitted by a single distribution such as beta, lognormal, gamma, Pareto, etc., while the effects by the underlying sub-distributions within the overall distribution are generally ignored. Finite mixture model (FMM) is a widely used probabilistic model to make statistical inferences on parameters from an unknown distribution in terms of mixtures of known distributions. The new FMM procedure shipped with SAS 9.3 makes the building and diagnose of the finite mixture model much easier. In this paper, we illustrate how to create valid finite mixture models for Loss Given Default (LGD) by an example of a credit portfolio with 317 obligors.
