Collaborative Amateur Production of Educational Videos,which are Viewed on Mobiles: Addressing Poor Technical Resources for Nigerian Creative Arts Academics

This research was a co‐creation and co‐assessment exercise between the researchers, participating printmaking and weaving academics and their students in a Nigerian university. The poor technical resources and increasingly large student groups in the design department, which severely hampers the delivery of an effective education, were addressed. The academics were supported to learn how to create their own instructional videos for their students, demonstrating identified designer‐maker skills and how to use required equipment. These academics are now empowered and have the knowledge to produce their own instructional videos without professional assistance. This is also irrespective of their previous experiences of using video equipment and developing video content.     

Transfer of strategy use by semantic recoding in arithmetic problem solving

Transfer of strategies between problems sharing the same formal structure is facilitated by a semantic recoding that makes evident the structural similarities between the problems. Two experiments were carried out among 4th and 5th grade pupils, with an experimental group trained to compare strategies in order to reinterpret an arithmetic word problem so that the calculations are consistent with the interpretation, and a control group. The experimental group in Experiment 1 improved significantly by choosing the alternative strategy in problems different from those used in training but no significant progress was observed in the control group. Experiment 2 showed that the improvement observed in the experimental group could not be attributed to the fact that children only learned to use a superficial rule. These results support the idea that the activity of problem re-representation may be a crucial step in mathematization.     

Review：Proteomic technology for biomarker profiling in cancer： an update

CANCER BIOMARKERS: CURRENT STATUS Despite advances in diagnostic imaging technol-ogy, surgical management, and therapeutic modalities,cancer remains a major cause of mortality worldwide.Currently, it is estimated that cancer kills over 6 mill-ion people per year worldwide, with over 10 millionnew cases being diagnosed every year. Mortality ismainly attributed to dissemination of primary cancerto distant organs, on which no effective treatment isavailable. The dilemma in oncology p…     

Towards culturally relevant classroom science: a theoretical framework focusing on traditional plant healing

A theoretical framework is an important component of a research study. It grounds the study and guides the methodological design. It also forms a reference point for the interpretation of the research findings. This paper conceptually examines the process of constructing a multi-focal theoretical lens for guiding studies that aim to accommodate local culture in science classrooms. A multi-focal approach is adopted because the integration of indigenous knowledge and modern classroom science is complex. The central argument in this paper is that a multi-focal lens accommodates the multifaceted nature of integrating indigenous knowledge and western oriented classroom science. The objective of the paper, therefore, is to construct a theoretical framework that can be used to guide and inform the integration of indigenous knowledge and western science at classroom science level. The traditional plant healing form of indigenous knowledge is used as a case study. The paper is important for raising the complexities, tensions and dilemmas inherent in the design and implementation of indigenous knowledge-science integrated curricula. An understanding of the issues raised will pave the way towards achieving culturally relevant classroom science.     

Operational space consensus of multiple heterogeneous robots without velocity measurements

This paper proposes a control algorithm for networks of multiple heterogeneous robot manipulators, which solves the leader–follower and the leaderless consensus problems in the operational space. In the leader–follower scenario, the controller ensures that all the robots in the network asymptotically reach a given leader pose (position and orientation), provided that, at least, one follower robot has access to the leader pose. Without a leader pose, in the leaderless problem, the robots asymptotically reach a pose of consensus. The controller is a simple distributed proportional plus damping injection (P+d) scheme which does not require velocity measurements. A singularity-free representation, unit quaternions, is used to describe the orientation of each manipulator. The paper presents some simulations, with a network of six 6-Degrees-of-Freedom (DoF) manipulators, and experiments, with a network of three 6-DoF manipulators, to show the effectiveness of the proposed controller.     

Physico-chemical characterization of a farmland affected by wastewater in relation to heavy metals

This study investigated selected properties of soils affected by wastewater and its relationship with some heavy metals A free survey technique involving target sampling was used in siting soil profile pits. Soil samples were collected based on horizon differentiation and analyzed using routine and special analytical techniques. Soil data were subjected to correlation analysis using SAS program. Results show that all heavy metals studied had values above critical limits in the polluted soils using known standards and that these biotoxic metals decreased with soil depths. Highly significant （P=0.01 and 0.05） relationships were established between investigated heavy metals and some soil properties, especially soil pH and organic matter. Further studies involving more edaphic properties, biotoxic metals and their bioaccessibility in crops growing on wastewater soils will surely enhance knowledge and management of these highly anthropogenically influenced soils of the study site.     

Hacia una formalización de los procesos implicados en la comprensión musical

El principal problema que se plantea en la comparación músical lenguaje estriba en la naturaleza de los procesos implicados en la percepción y comprensión de las producciones musicales. En este artículo se plantean ciertas precauciones a la hora de trasponer sin más los modelos de análisis formales del lenguaje a la música, abogando por la teoría generativa de Lerdahl y Jackendoff y analizando sus implicaciones para la formación musical.     

The mental and physical health difficulties of children held within a British immigration detention center: A pilot study

ObjectiveThe present study aimed to assess the mental and physical health of children held within a British immigration detention center.MethodA total of 24 detained children (aged 3 months to 17 years) were assessed with their parents or carer after being referred by a registered legal charity. Thirteen were seen by a pediatrician alone, 4 by a psychologist alone, and 7 by both professions using semi-structured clinical interviews. The psychologist also used standardized self-report questionnaires to measure psychopathology.ResultsDuring the psychological assessment of 11 children, 8 met criteria for psychiatric “caseness” on the Strengths and Difficulties Questionnaire. All 11 reported symptoms of depression and anxiety. Sleep problems, somatic complaints, poor appetite, emotional symptoms, and behavioral difficulties were common. Symptoms of global distress were also reported by all 9 parents. According to pediatric assessment 8 out of 20 children had lost weight. Six had missed health appointments and 2 were taken to hospital. Nutritional, developmental, educational, and child protection concerns were raised.ConclusionsDetained children were found to be experiencing mental and physical health difficulties of recent onset, which appeared to be related to the detention experience. These findings support previous Australian studies demonstrating that detention is not in the best interest of the child. It suggests that current UK policies regarding the detention of children for purposes of immigration control should be re-examined. Further research in the area is required.Practice implicationsAlthough high levels of mental and physical health problems, as well as child protection concerns were detected, detained families had very limited access to appropriate assessment, support or treatment. The traumatic experience of detention itself also has implications for the sizeable proportion of psychologically distressed children who are eventually released from detention and expected to successfully reintegrate into British society; while those children who are deported are returned with increased vulnerability to future stressors.
