title: The Neolithic of Vietnam

authors: Piper, Philip J.

subjects: Vietnam

abstract: The Neolithic in Mainland Southeast Asia is considered to be the period of human prehistory that commenced with the transition from hunting and gathering into mixed economies of foraging and farming. It lasted until the appearance of copper and bronze metallurgy and thus dates between circa 2500 and 1200 BC. In Vietnam, Neolithic sites and cultures are recorded especially around the edges of the Red River delta, along the northern and central coasts, and in the southern river basins between the Đông Nai and lower Mekong. This period of Vietnamese prehistory was characterized by the southward movements of East Asian Neolithic populations from southern China across Mainland Southeast Asia, the introduction of cereal cultivation (rice and foxtail millet), and the management of domesticated pigs and dogs. The Neolithic of Vietnam also reveals material culture relationships extending from southern China to central Thailand. Recent research is also starting to highlight social and cultural diversity during this period, together with the development of significant exchange networks.

title: Supercapacitor assisted low dropout regulators (SCALDO) with reduced switches: A new approach to high efficiency VRM designs

authors: Kularatna, Nihal

subjects: VRM

abstract: Supercapacitor assisted low dropout (SCALDO) regulator is a new approach to develop high efficiency DC-DC converters with supercapacitors used for energy recovery. One limitation in these topologies is that in some configurations a large number of low-speed switches are required. If the SCALDO technique is adapted to build voltage regulator modules (VRM), it is necessary to reduce number of switches combined with a high current capable LDO. A new topology-variation with less number of switches can be achieved by reconfiguring the original SCALDO and adding an extra LDO to the circuit. The paper presents a summary of some preliminary work, and experimental results for a 2.5V proof of concept-prototype.

title: Coaching for the game of life: Driving coaching with mana

authors: Were, Brandyn Māia

subjects: Kaupapa Māori

abstract: Coaching needs to account for culture. This indigenous autoethnography explores personal experience to show how I, a young Māori male coach in Aotearoa New Zealand, navigates the complex nature of coaching. By weaving together Kaupapa Māori, established coaching knowledge, and experiences from my playing and coaching journey to date, a Kaupapa Māori coaching framework emerges – Driving Coaching with Mana.

As I reflect on the teachings of my coach, Mr. Mel Young, combined with my cultural identity, I reconnect to critical moments in my life that have shaped the person I am today and the values I hold, elevating the centrality of culture through the practice of Kaupapa, Ako, Manaakitanga, Whanaungatanga, Wairuatanga, and self-reflection as Āta-kaiako (a reflective coach).

Driven to enhance the development of rangatahi (youth) through sport, and informed by literature and experience, Driving Coaching with Mana is personally and culturally grounded – a way of thinking about coaching differently and in a more holistic way. There is more to the people we coach than their lives as athletes. Coaching is more than skill acquisition.
