Equipping the Church Deacons of Chai Wan Evangelical Church with an Adaptive Leadership Approach

Chai Wan Evangelical Church was established with a “burden for evangelism [and the] pursuit of godly life,” according to its mission statement. The primary of goal of the church is to share the gospel and nourish Christians to become holy. In 2007, the church launched a student ministry, which resulted in an increase in evangelical and pastoral needs. In order to work well with the young leaders who are working with this ministry, a new paradigm for leadership is needed. Therefore, the purpose of this project is to develop a training plan for the deacons to be adaptive leaders. Part One of this project explores the formation of leadership approach at Chai Wan Evangelical Church. This section also explores why the church’s current leadership approach is ineffective, while the evangelical and pastoral needs increase. Finally, this section describes the reasons for the implementation of adaptive leadership. Part Two presents a theological reflection upon the challenge of church leadership. The importance of leadership for the church is discussed. The biblical theology of adaptive leadership is examined in order to give an account for its applicability and implications in a new era. In the light of the leadership challenge before Chai Wan Evangelical Church and the theological understanding of leadership put forth in Part Two, Part Three presents a practical strategy for equipping deacons with adaptive leadership. It explains how key leaders, including deacons and young potential leaders, are recruited and trained, then adopt to exercise the new introduced leadership approach. This section also explains how the project will be assessed

Adaptive Navigation of Three-Dimensional Scalar Fields with Multiple UAVs

Adaptive Navigation (AN) control strategies allow an agent to autonomously alter its trajectory based on realtime measurements of its environment. Compared to conventional navigation methods, AN techniques can potentially reduce the time and energy needed to explore scalar characteristics of unknown and dynamic regions of interest (e.g., temperature, concentration level). Multiple Uncrewed Aerial Vehicle (UAV) approaches to AN can improve performance by exploiting synchronized spatially-dispersed measurements to generate realtime information regarding the structure of the local scalar field for use in navigation decisions. This dissertation presents initial results of a comprehensive program to develop, verify, and experimentally implement mission-level AN capabilities in three-dimensional (3D) space using Santa Clara University’s (SCU) unique multilayer control architecture for groups of vehicles. Using SCU’s flexible formation control system, this work builds upon prior 2D AN research and provides new contributions to 3D scalar field AN by a) demonstrating a wide range of 3D AN capabilities using a unified, multilayer control architecture, b) extending multivehicle 2D AN control primitives to navigation in 3D scalar fields, and c) introducing state-based sequencing of these primitive AN functions to execute 3D mission-level capabilities such as isosurface mapping and plume following. Functionality is verified using high-fidelity simulations of multivehicle drone clusters which account for vehicle dynamics, outdoor wind gust disturbances, position sensor inaccuracy, and scalar field sensor noise. This dissertation presents the multilayer architecture for multivehicle formation control, the 3D AN control primitives, the sequencing approaches for specific mission-level capabilities, and simulation results that demonstrate these functions

Assessing Community Impact after Service-Learning: A Conceptual Framework

Service-learning integrates experiential learning with community service, yet its community impacts have not been systematically studied. This may reflect the lack of a conceptual model for impact assessment, and failure to investigate the end-beneficiary’s perspective. This study proposes a tripartite model, in which the community impact of service-learning is analyzed from three perspectives: that of the community partner, the end-beneficiary, and the service-learning intervention itself. The model identifies three impact domains salient for the community partner: the level of capacity for service; goals and value achieved; and new knowledge and insights gained. For impact domains salient for the end-beneficiary, the model utilises the needs fulfilment matrix developed by Max-Neef (1991), along with the concept of quality of life. It is argued that the model can accommodate the community impact generated from the community partner, the end-beneficiary and their interactions.Lau, KH.; Snell, R. (2020).

Conceptual Framework for Assessing Process Variables Salient for Service-Learning Experience

[ES] Service-learning is an established pedagogy which integrates experiential learning with community service. It has been widely adopted in higher education around the world including in Hong Kong, yet the key ingredients that determine its successful impacts for its stakeholders have not been fully assessed. This study reviewed the past literature, which indicates the key ingredients that may be found in successful service-learning programmes. We identify six key ingredients: students provide meaningful service; the community partner representative plays a positive role; effective preparation and support for students; effective reflection by students; effective integration of service-learning within the course design; and stakeholder synergy in terms of collaboration, communication and co-ownership. In order to obtain an inter-subjectively fair and trustworthy data set, reflecting the extent to which those key ingredients are perceived to have been achieved, we propose a multi-stakeholder approach for data collection, involving students, instructors and community partner representatives.Snell, R.; Lau, KH.

Android based text messaging for opportunistic network

Android operating system is dominating the mobile device operating system. There are many text messaging applications are available to download from Google Play Store, and install on the device. The existence of text messaging applications is slowly replacing the usage of Short Message Service (SMS) as the applications can send and receive text messages without any charges. However, these text messaging applications are needed to connect to Internet in order to send and receive messages. As today's smartphones are able to create and join any wireless network, opportunistic network that involve a great mobility nodes will be able to reduce its difficulty to implement. Opportunistic network doesn't have a persistent end-to-end path between the source and destination. The data will be exchanged and transmitted by the opportunistic contact between intermediate nodes. In this project, an Android-based text messaging application is designed and developed, and expected to work in opportunistic network

The effect of increased microporosity on bone formation within silicate-substituted scaffolds in an ovine posterolateral spinal fusion model

This study compared the bone forming capacity of the same formulation of silicate-substituted bone graft substitute materials with different microporosity in an instrumented posterolateral spinal fusion ovine model. Materials with a strut porosity of (i) 22.5% (SiCaP) or (ii) 36.0% (SiCaP(+)) were packed along either side of the spine. Bone apposition rates, % new bone formation, % bone-implant contact, and % graft resorption were quantified at 8, 12, and 24 weeks post surgery. Computed Tomography (CT) was used to grade the formation of fusion bridges between vertebrae. Results showed no significant difference in bone apposition rates, % new bone formation, and % bone-implant contact when the two materials were compared. However, at 8 weeks, a significantly higher CT score was obtained in the SiCaP(+) group (0.83±0.17) when compared with the SiCaP group (0.17±0.17; p=0.027). Significantly less scaffold remained in the SiCaP(+) group at 12 weeks (p=0.018). Both SiCaP and SiCaP(+) formulations augmented bone formation. Increasing the strut porosity did not significantly increase bone formation however, at 8 weeks it promoted the formation of more highly mineralized bone resulting in a significantly higher CT score, suggesting the bone tissue formed was more mature
