The impacts of Delphi communication structure on small and medium sized asynchronous virtual teams
The improvement of Internet technology has motivated distributed work groups to collaborate without meeting face to face. Although asynchronous meetings through Web-based group communications systems enable groups dispersed temporarily and geographically to collaborate more flexibly, parallel and non-linear communication among dispersed members also challenge effective and efficient group coordination. Moreover, the Web-based asynchronous meeting is distinguished not only from the face-to-face meeting but also from the synchronous computer-supported meeting in terms of coordination process. However, previous asynchronous group communications or virtual team research focused more on the comparison of this new type of meeting with the face-to-face meeting. Not many research efforts have been exerted to improve the productivity of this new form of meeting and find ways to overcome its disadvantages. Facilitation was proved effective to enhance the productivity of synchronous meetings. However the effect of structured discussion through facilitation was not clear in asynchronous meeting settings even though facilitation is a common practice in asynchronous group communication systems.
This study examined the effect of a facilitated structure in improving the productivity of asynchronous decision-making groups. Delphi was chosen as the facilitated structure because it has been widely used as the paper-and-pencil-based structure to facilitate dispersed experts in collecting their opinions. In this study a computer-based Delphi structure was implemented through asynchronous Computer-Mediated Communication. A 2X2 controlled experiment was conducted to investigate the effect of Delphi structure on the effectiveness of small-sized (5-6 members) and medium-sized (10-12 members) asynchronous computer-supported groups. The formal facilitation using Delphi structure was effective to improve the productivity of asynchronous groups in generating more ideas. On the contrary, informal leadership by group coordinators seems to have played a more important role in producing better reports. In terms of per person ideas, small-sized groups were more productive, even though medium-sized groups produced more total ideas than small-sized groups. The superiority of Delphi groups and small-sized groups is related to their higher equality of participation. This result suggests that in asynchronous meetings, equal participation of group members in discussion is important in improving idea generation productivity while in synchronous meetings, the process loss of production blocking plays a crucial role
Tendências no desempenho em matemáticas e ciências em 18 países: análise de regressão múltipla de efeitos de coorte no TIMSS 1995-2007
The purpose of this study was to simultaneously examine relationships between teacher quality and instructional time and mathematics and science achievement of 8th grade cohorts in 18 advanced and developing economies. In addition, the study examined changes in mathematics and science performance across the two groups of economies over time using data from the TIMSS 1995-2007 assessments. While economy did not account for variation in mathematics and science achievement, findings from regression analyses indicated significant relationships between school inputs and achievement in both groups of countries across the years. Teaching experience was a strong indicator of mathematics performance in developing countries, while instructional time was mildly related to achievement in both subjects in advanced economies.El objetivo de este estudio fue examinar simultáneamente las relaciones entre la calidad docente y el tiempo de instrucción y los logros en matemáticas y ciencias de una cohorte de 8° grado en 18 economías avanzadas y en desarrollo. Además, el estudio examinó los cambios en el rendimiento en matemáticas y ciencias entre dos grupos de economías a lo largo del tiempo utilizando los datos de las evaluaciones de TIMSS de 1995-2007. Aunque la variable “economía” no mostró variación en los resultados de logros de aprendizaje en matemáticas y ciencias, los análisis de regresión muestran relaciones significativas entre los insumos escolares y logros de aprendizaje en los dos tipos de países a lo largo de los años. La experiencia docente fue un fuerte indicador del rendimiento en matemáticas en los países en desarrollo, mientras que el tiempo de instrucción se relaciona medianamente con el rendimiento en ambas materias en las economías avanzadas.O objetivo deste estudo foi examinar, simultaneamente, as relações entre a qualidade do professor e o tempo de instrução e os resultados em matemática e ciências de grupos do último ano do ensino básico (8th grade) em 18 economias avançadas e em desenvolvimento. Para além disso, o estudo examinou as mudanças no desempenho em matemática e em ciências entre os dois grupos de economia ao longo do tempo, usando dados das avaliações do TIMSS 1995-2007. Embora a economia não conte para a variação nos resultados em matemática e ciências, os resultados das análises de regressão indicam relações significativas entre as condições das escolas e os resultados em ambos os grupos de países, ao longo dos anos. A experiência de ensino foi um forte indicador do desempenho em matemática em países em desenvolvimento, enquanto o tempo de instrução relacionou-se moderadamente com os resultados alcançados em ambas as disciplinas em economias avançadas
a case of gomdallaekkum maeul in Seoul
Thesis(Master) -- KDI School: Master of Development Policy, 2022The Seoul Metropolitan Government has been promoting a Management-Type Residential Environment Improvement Project that comprehensively improves the residential environment of low-rise residential areas through collaborative governance supporting community activation. However, a recent shift in the urban regeneration paradigm in Seoul has raised questions about collaborative governance as a tool for resident participatory planning in urban planning and management. This study focuses on the collaborative governance supporting community activation in the management-type residential environment improvement project through the example of Gomdallaekkum Maeul in Sinwol 1-dong, Yangcheon-gu, Seoul. Especially, Gomdallaekkum Maeul’s community organization shows evidence of establishing a virtuous cycle of public-private partnerships and collaboration between local networks in the COVID-19 pandemic period where community activities are restricted. Therefore, based on the case of reinforcement and extension of collaborative governance following the interaction of the unique community activation of Gomdallaekkum Maeul, a new perspective on the management-type residential environment improvement project is presented.1.

The Rochester Institute of Technology: An Interactive computer disk
The nature of this thesis is to explore the possibilities of interactive animation. An animated, interactive program which shows various activities and programs of the Rochester Institute of Technology, (R.I.T.), is the finished product. R.I.T\u27s history, upstate New York location, and academic philosophies are incorporated. The interactive disk contains information about the various programs the college offers, as well as, many examples of actual student work. It also shows these students creating their projects. In their own words, they tell about their lives at R.I.T., both in and out of the classroom. Faculty and staff also offer their views, lending another perspective of R.I.T\u27s philosophies and beliefs. Because R.I.T. offers a various array of programs, highlighted are only some of the programs available at R.I.T. The shown in detail are the College of Imaging Arts and Sciences. Cooperative experiences offered at R.I.T. , and the financial aid available to students are also described. The video images include interviews and discussions with many of the departmental leaders of the campus, as well as, interviews with students of different cultures, backgrounds, and programs. This interactive program was created by using numerous computer software packages which is the actual heart of the thesis. The program has been built around Macromind Director, VideoFusion, Specular Logo Motion and Morph and Adobe Premiere. Any retouching has been completed by using the Photoshop program. The combining of all these programs results in the end product : an interactive disk

One-pot Enzymatic Synthesis of Deoxy-thymidine-diphosphate (TDP)-2-deoxy-∝-d-glucose Using Phosphomannomutase
Production of deoxy-thymidine-diphosphate (TDP)-sugars as substrates of glycosyltransferases, has been one of main hurdles for combinatorial antibiotic biosynthesis, which combines sugar moiety with aglycon of various antibiotics. Here, we report the one-pot enzymatic synthesis of TDP-2-deoxy-glucose employing high efficient TMP kinase (TMK; E.C. 2.7.2.12), acetate kinase (ACK; E.C. 2.7.1.21), and TDP-glucose synthase (TGS; E.C. 2.7.7.24) with phosphomannomutase (PMM; E.C. 5.4.2.8). In this study, replacing phosphoglucomutase (PGM; E.C. 5.4.2) by PMM from Escherichia coli gave four times higher specific activity on 2-deoxy-6-phosphate glucose, suggesting that the activity on 2-deoxy-glucose-6-phosphate was mainly affected by PMM activity, not PGM activity. Using an in vitro system starting from TMP and 2-deoxy-glucose-6-phosphate glucose, TDP-2-deoxy-glucose (63% yield) was successfully synthesized. Considering low productivity of NDP-sugars from cheap starting materials, this paper showed how production of NDP-sugars could be enhanced by controlling mutase activity
