Ipma's Analysis on Factors Affecting Indrive Indonesia's Customer Loyalty

Purpose:  The purpose of this study was to identify the factors that influence customer loyalty to indrive application users in the city of Bandung, Indonesia using IPMA analysis on SmartPLS   Theoretical framework:   This research is a development of theoretical aspects of the online transportation industry in Indonesia which consists of app design and trust variables as moderator variables between e-service quality and customer satisfaction. Then there is price, value for money and perceived quality which affect customer satisfaction, and customer satisfaction will affect customer loyalty.   Design/methodology/approach:  This study uses a quantitative method with data sources derived from surveys through the distribution of online questionnaires to 160 inDrive application users. The data analysis technique used is SEM-PLS and IPMA Analysis using SmartPLS software.   Findings:   Customer satisfaction is the variable that most influences customer loyalty of inDrive application users in Bandung based on IPMA Analysis, because it has the highest performance value when compared to other variables   Research, Practical & Social implications:   InDrive management must pay attention to customer satisfaction for each inDrive application user in the city of Bandung in order to achieve, maintain the consistency and sustainability of the inDrive company in the city of Bandung to maintain customer loyalty.   Originality/value:  The study is the first study conducted to analyze the factors that influence customer loyalty in indrive application users in the Bandung City, Indonesia, so that it can be a reference and additional reference on academic knowledge and managerial aspects

Code-switching in the English Second Language classroom: a case study of four rural high school teachers in uMbumbulu, KwaZulu-Natal.

Doctoral Degrees. University of KwaZulu-Natal, Durban.Due to the multicultural setting of South Africa, eleven languages, which include English, Afrikaans and nine indigenous languages including Xhosa, Zulu, Swati and Ndebele, Southern and Northern Sotho, Tswana, Venda and Tsonga, have been awarded equal status as official languages. Despite the continued support for English as the prestigious language of wealth and success from Black parents, English Second Language (ESL) learners are often found to struggle in developing the expected competency in the language both inside and outside the classroom. The Department of Education expects teachers to be skilled in assisting learners who experience a barrier to learning and understanding English in the ESL classroom. This study argues that teacher’s Code Switching (CS) provides solace for learners who struggle to understand what is taught in class. Despite the feeling of justification for CS use in ESL classrooms, teachers feel they are not only breaching the official language policy but, also, what is presented to them as best classroom practice. In this thesis, I attempt to show the necessity and value of CS in such circumstances. Although a large body of research has been done on ESL classroom codeswitching, there is a shortage of such studies in Black rural high schools. This study aimed to explore where, when and how instances of teacher CS occur in four rural high school ESL classrooms, the attitudes teachers have towards it, as well as, their experiences of using it in the classroom. Through utilizing three research instruments, namely, concepts maps, open-ended questionnaires and open-ended audio-recorded telephone interviews, data was collected over a period of six months. Findings in this study indicate that CS is still widely used by ESL teachers and considered successful in clarifying difficult concepts in Literature and Comprehension. Learners were found to enjoy lessons and were actively involved throughout the activities that were performed in class. On the other hand, teachers expressed feelings of resentment towards CS use in ESL classrooms maintaining that it makes learners lazy to independently learn the new vocabulary necessary to develop their competency in English language

Minimum Sparsity of Unobservable Power Network Attacks

Physical security of power networks under power injection attacks that alter generation and loads is studied. The system operator employs Phasor Measurement Units (PMUs) for detecting such attacks, while attackers devise attacks that are unobservable by such PMU networks. It is shown that, given the PMU locations, the solution to finding the sparsest unobservable attacks has a simple form with probability one, namely, $\kappa(G^M) + 1$, where $\kappa(G^M)$ is defined as the vulnerable vertex connectivity of an augmented graph. The constructive proof allows one to find the entire set of the sparsest unobservable attacks in polynomial time. Furthermore, a notion of the potential impact of unobservable attacks is introduced. With optimized PMU deployment, the sparsest unobservable attacks and their potential impact as functions of the number of PMUs are evaluated numerically for the IEEE 30, 57, 118 and 300-bus systems and the Polish 2383, 2737 and 3012-bus systems. It is observed that, as more PMUs are added, the maximum potential impact among all the sparsest unobservable attacks drops quickly until it reaches the minimum sparsity.Comment: submitted to IEEE Transactions on Automatic Contro

High-throughput isolation and characterization of untagged membrane protein complexes: outer membrane complexes of Desulfovibrio vulgaris.

Cell membranes represent the "front line" of cellular defense and the interface between a cell and its environment. To determine the range of proteins and protein complexes that are present in the cell membranes of a target organism, we have utilized a "tagless" process for the system-wide isolation and identification of native membrane protein complexes. As an initial subject for study, we have chosen the Gram-negative sulfate-reducing bacterium Desulfovibrio vulgaris. With this tagless methodology, we have identified about two-thirds of the outer membrane- associated proteins anticipated. Approximately three-fourths of these appear to form homomeric complexes. Statistical and machine-learning methods used to analyze data compiled over multiple experiments revealed networks of additional protein-protein interactions providing insight into heteromeric contacts made between proteins across this region of the cell. Taken together, these results establish a D. vulgaris outer membrane protein data set that will be essential for the detection and characterization of environment-driven changes in the outer membrane proteome and in the modeling of stress response pathways. The workflow utilized here should be effective for the global characterization of membrane protein complexes in a wide range of organisms

Proceedings Ocean Biodiversity Informatics: International Conference on Marine Biodiversity Data Management, Hamburg, Germany 29 November to 1 December, 2004

The International conference on Marine Biodiversity Data management ‘Ocean Biodiversity Informatics’ was held in Hamburg, Germany, from 29 November to 1 December 2004. Its objective was to offer a forum to marine biological data managers to discuss the state of the field, and to exchange ideas on how to further develop marine biological data systems. Many marine biologists are actively gathering knowledge, as they have been doing for a long time. What is new is that many of these scientists are willing to share their knowledge, including basic data, with others over the Internet. Our challenge now is to try and manage this trend, avoid confusing users with a multitude of contradicting sources of information, and make sure different data systems can be and are effectively integrated
