title: Roadmap on signal processing for next generation measurement systems

authors: Iakovidis, Dimitris K.

subjects: Science & Technology

abstract: Signal processing is a fundamental component of almost any sensor-enabled system, with a wide range of applications across different scientific disciplines. Time series data, images, and video sequences comprise representative forms of signals that can be enhanced and analysed for information extraction and quantification. The recent advances in artificial intelligence and machine learning are shifting the research attention towards intelligent, data-driven, signal processing. This roadmap presents a critical overview of the state-of-the-art methods and applications aiming to highlight future challenges and research opportunities towards next generation measurement systems. It covers a broad spectrum of topics ranging from basic to industrial research, organized in concise thematic sections that reflect the trends and the impacts of current and future developments per research field. Furthermore, it offers guidance to researchers and funding agencies in identifying new prospects.

title: Impediments to Effective Enactment of Early Childhood Education Curriculum and Pedagogy in Tanzania: Issues and Experiences of Teachers in Urban and Rural Pre-Schools

authors: Mligo, Ignasia Renatus

subjects: Early childhood curriculum enactment

abstract: The purpose of this study was to investigate experiences, possibilities, and issues encountered by teachers in the enactment of early childhood education and care curriculum and pedagogy in the Tanzanian context. Worldwide, the concept of early childhood education and care does not refer to a single entity; rather, the term covers a variety of programmes for young children between birth and eight years. It is theorised in the literature that improving human development in the early years in good quality early education, is definitely a way to break out of poverty because early investment has a very high economic rate of return.
The government of Tanzania formalised pre-school education for children aged 5 and 6 years old under the Tanzania’s Education and Training Policy in 1995 and placed it under the direction of the Ministry of Education. Having formalised pre-school education, the government in partnership with parents, community, and non-governmental organisations agreed to support this education. However, anecdotes suggested that all activities to implement the policy were left to parents, communities, and non-governmental organisations. Hence, it was suspected that there might be challenges, experiences, and possibilities arising when teachers enact the current pre-school education curriculum developed in 2005, and associated pedagogies in the classroom context.
This study within an interpretive paradigm took a case study approach to investigate participants’ views on the enactment of the Tanzanian pre-school education curriculum and associated pedagogies. Views on the curriculum enactment were elicited from 28 participants; six from government educational officials (national level) and 22 from the local level (six teachers, four parents, and 12 pre-school children) in the one rural and the one urban pre-school. Multi-methods were used to generate data through individual interviews, focus group discussions, classroom observations, documentary review, informal conversations, and the researcher’s reflective journal. Data were analysed thematically by NVivo 10 software developed by QSR International.
Ecological systems theory developed by Urie Bronfenbrenner (1917-2005), and sociocultural theories developed by Lev Semenovich Vygotsky (1896-1934) were used as lenses for framing the study, data analysis, interpretation of findings, and drawing conclusions.
The findings revealed that there was a mismatch between the intended pre-school education curriculum and the curriculum enacted by teachers in the field. The data analysis indicated that this ineffective enactment of the curriculum and associated pedagogies in the field was influenced by lack of clear policy guidelines as to how pre-school education would be funded and conducted (i.e. structural and quality aspects), limited human and physical resources, lack of involvement of the key users on curriculum development, lack of awareness of parents and community regarding the importance of early education investment, and detrimental cultural beliefs and traditions practiced in relation to young children. Hence, in public pre-school settings studied, parents and the community were not able to provide quality pre-school education. Quality pre-school education in the international literature indicates the importance of learner-centred pedagogy.
However, few studies conducted in the Tanzanian context have written on the importance of learner-centred pedagogy in teaching and learning. Moreover, those studies that have been carried out have not indicated how learner-centred pedagogy could be enacted in the Tanzanian context. So, this study has provided a number of suggestions to inform government policy makers of ways to implement learner-centred pedagogies for quality early childhood education and care.
To that end, the study concludes that for the better enactment of pre-school education curriculum and pedagogical practice, there is a need for the government to prioritise in early education. It needs to involve parents and community to work with qualified teachers and local experts to develop child-centred pedagogy. Together with this, the study contributes to knowledge by developing an early childhood education and care model aiming at promoting capacity building for parents, community volunteers, teachers, and children for quality early education provision.

title: The Wairua of Self: A Path of Love, Simplicity, and Connectedness

authors: Frishman, Lezlie

subjects: love

abstract: Love is an action of freedom until something else steps in – often fear – that insists we create a box of survival. Whether self-imposed, forced, or chosen, it is interesting to notice how we limit ourselves with love. This thesis examines love; love in its purest intent and creation as the simplest way to live. An analysis of personal experiences, illuminated by psychological, mythological, philosophical, and spiritual literature, suggests that living from a place of love can be accomplished through a dedicated journeying back to the Self. The Māori myth of Tāne-Mahuta and Hine-Tītama shows the significance of releasing shame, as well as how a tragic situation might offer a catalytic possibility that shifts a core belief about one’s self. The complications of love that are self-created through loss and grief can easily mask the barely underlying truth of love in its nakedness. Reconnecting with this underlying truth, aroha in its purest sense, is essential for healing and allows for increased connection with the Divine. Doing so is often a difficult task, as hypocrisies fueled by fear and perpetuated by blame are bountiful. When love is used as an instrument and convenience in order to defend a closely held idea, person, or way of life, one often moves further from their true Self, thus surrendering their deepest power and knowing of love. The silent assault of expectations, power, will, and control can turn love into a complication. The complications of being utterly human only serve to further obscure love. Within families, how one initially learns love is often complicated by interrupted attachment, causing rebellion and the need to look for love elsewhere. The components of Tikkun Olam, aroha, mikveh, and wairua of spirit, are intertwined and interconnected, such that the delineation between cultures and spiritual beliefs cannot be divided as oppositional forces. The denominator lives in the magnitude of love for all that has been created; beginning with the Self. In setting the foundation of self-love and allowing it to settle into the fractures and rifts of porousness, love may then be extended without attachment. When freely proffered without agenda, love will seep into every curve of the universe; thus, changing the world. Through the practice of mindfulness and loving-kindness, perception can change. It is this change in perception which can return love to its origin of simplicity. This thesis is a story of love.
