Toward a Theology of Mission Partnerships
No full text Beginning with a consideration of the meaning of “partnership” as that has been understood by the various Christian traditions in the twentieth century, the author bases his theology of mission partnerships on a missiological reading of Ephesians 4:1 to 5:2. Drawing from the major emphases of Paul's thought in the text, Van Engen argues that because the church's oneness is centered in Jesus Christ (the motivation for mission), Christians are called to partner together for world evangelization, serving one another in love and humility (the agency of mission) as they participate in Christ's mission, offering to one another the unique gifts given by the Holy Spirit to their various regional and global organizations and churches (the means of mission), so that they may equip the saints for the work of ministry until they all together grow up into the measure of the stature of the fullness of Christ (the goals of mission partnerships). </jats:p

My Pilgrimage in Mission
No full text Charles Van Engen summarizes his pilgrimage in mission: “I have lived a life invested in forming people as leaders, paying forward what others did for me.” Born of missionary parents, Chuck was raised in southern Mexico. From 1973 to 1985 Chuck and his wife, Jean, served in Chiapas, Mexico, in leadership formation. In 1981 Chuck received a Ph.D. in missiology under Johannes Verkuyl at the Free University of Amsterdam, followed by teaching mission theology in Michigan and, for twenty-seven years, at Fuller Theological Seminary. The Van Engens lead a ministry that provides PhD-level theological education to Latin American leaders. </jats:p

Assessing meditation through electroencephalographic data: a dynamical systems approach
No full textMeditation is a contemplative practice that is believed to entail attentional and emotional regulation. One of the biggest challenges in developing personalized, accessible healthcare options with meditation is finding understandable features that signify whether someone is meditating. Specifically, there is no consensus on a feature resulting from the electroencephalogram (EEG) in the current body of literature on meditation.In this thesis, I propose a dynamic systems analysis on EEG data to obtain a dynamic feature capable of distinguishing meditation from an eyes-closed resting baseline. I gathered the EEG data at TNO (Dutch Organisation for Applied Scientific Research) from twenty-two participants during a sixteen-minute loving-kindness meditation and two two-minute baselines. The proposed methodology characterizes temporal and spatial characteristics of the EEG simultaneously by approximating the EEG dynamics with a linear model on short time windows. I assess changes among three features: the frequency and magnitude of the oscillatory dynamics and the corresponding active electrodes.The analysis can identify changes in EEG dynamics for each individual. Across all participants, regions associated with vision and language processing were active throughout the experiment. Notably, attention-related regions were more involved during meditation than rest. Moreover, the results show a shift in active regions throughout the meditation and the baselines for several participants.Moreover, the thesis investigates the sensitivity of the analytical approach to changes in the electrode subset used for the analysis. For each participant, I constructed a subset of electrodes that were most involved in the changing EEG dynamics. The personalized subset was most sensitive to changes between meditation and rest, compared to other subsets based on commercial wearable EEG headsets. Finally, I compare the findings of the dynamic systems approach to a conventional analytical approach, and the participants’ emotional ratings inquired in subjective questionnaires. Unfortunately, from the current data, there appears to be no relationship between the proposed features and the conventional measures or the subjective questionnaires.Mechanical Engineering | Systems and Contro
A study of business-to-business extranet usage at Engen Petroleum Ltd.
No full textMBA University of KwaZulu-Natal, Durban 2013.E-Commerce has revolutionised the manner in which modern business is conducted, with the extranet as one of the enabling tools. Concurrently, there has been an evolution in the methods of business-to-business buying, from telesales, to fax systems, and email systems, through to online buying systems. The adoption and utilisation of the extranet system has been widespread in the developed nations, however, are these trends similar in the developing countries? The aim of this study was to evaluate the adoption and utilisation trends of the extranet system by the customers of Engen Petroleum, Ltd, after the roll-out to key customers in 2002. The approach for this research was a quantitative and descriptive study, in order to serve the purpose of measuring and understanding the underlying reasons for the adoption and utilisation of the Engen extranet. The selected sampling method was a census type in order to achieve the required sample size. The total size of the active population was 56; a sample size of 49 was recommended for a 5% margin of error and for a 95% confidence interval. Data collection was conducted using an online, structured questionnaire, which was emailed to the participants. Of the total number of 56 possible participants, 47 customers participated in the survey, which made an 84 % response rate. The technology acceptance model (TAM) and the task technology fit (TTF) were the models used to conduct the research. The key outcome of the study showed poor utilisation of the Engen extranet tool, which meant that extranet adoption process at Engen is evolutional rather than revolutional. The survey showed that there was a positive perceived usefulness and intention to use the Engen extranet tool; however, there was negative perceived ease of use and task technology fit. It was concluded that the utilisation may be improved with more training and support especially among the buyers above 40 years of age. In order to leverage on the positive intention to use and perceived usefulness, it was recommended that the task technology fit could be improved, by enhancing functionality of the Engen extranet, using value-added services on the extranet website
