Online, Hybrid, and Face-to-Face Learning Through the Eyes of Faculty, Students, Administrators, and Instructional Designers: Lessons Learned and Directions for the Post-Vaccine and Post-Pandemic/COVID-19 World

This exploratory study builds upon the expertise of a panel of faculty, administrators, students, and instructional designers (IDs) who lived through the pandemic and dealt with the associated challenges firsthand. These participants provided insight on how to establish systems that would create successful online teaching and learning opportunities in the post-vaccine and post-pandemic world. Four major themes emerged: (a) integrating technology to facilitate and enhance education; (b) structural support and resources needed to build sound processes for effective online education; (c) establishing faculty presence to facilitate learning; and (d) joint ownership and responsibility of learning—everyone must play a part. These themes have been described in light of theoretical frameworks, such as the Technological Pedagogical and Content Knowledge (TPACK) model, Community of Inquiry (COI), and Continuous Quality Improvement (CQI). Finally, evidence-based tips will allow academic institutions to successfully emerge out of the pandemic while still making plans to adjust and adapt in the post-vaccine world.

The non-random structure of multi-trophic ecological interactions maximizes species coexistence within ecologically realistic constraints

Theory posits that the persistence of species in ecological communities is shaped by their interactions within and across trophic levels. However, we lack empirical evaluations of how the structure, strength and sign of these interactions drive the potential to coexist in diverse multi-trophic communities. Here we model community feasibility domains, a theoretically-informed measure of coexistence probability, from empirical data on communities comprising more than 50 species for three trophic guilds (plants, pollinators, and herbivores). Although feasibility domains vary depending on the number of trophic guilds considered, we show that higher network connectance leads to lower coexistence opportunities. Moreover, empirical estimations of the feasibility domains were higher with respect to random network structures but lower than a mean-field approach, suggesting that observed interaction structures tend to maximize coexistence within its imposed limits. Our results stress the importance of incorporating empirically-informed interaction structures within and across guilds to better understand how species coexist in diverse multi-trophic communities.

Single-cell imaging of Pseudomonas reveals dynamic polar accumulation of the extracellular iron-scavenger pyoverdin

Pyoverdin is a water-soluble metal-chelator synthesized by members of the genus Pseudomonas and used for the acquisition of insoluble ferric iron. Although freely diffusible in aqueous environments, preferential dissemination of pyoverdin among adjacent cells, fine-tuning of intracellular siderophore concentrations, and fitness advantages to pyoverdin-producing versus nonproducing cells, indicate control of location and release. Here, using time-lapse fluorescence microscopy to track single cells in growing microcolonies of Pseudomonas fluorescens SBW25, we show accumulation of pyoverdin at cell poles. Accumulation is induced by arrest of cell division, is achieved by cross-feeding in pyoverdin-nonproducing mutants, is independent of cell shape, and is reversible. Furthermore, it occurs in multi-species communities. Analysis of the performance of pyoverdin-producing and nonproducing cells under conditions promoting polar localization shows an advantage to accumulation on resumption of growth after stress. While the genetic basis of polarization remains unclear, evaluation of deletion mutants of pyoverdin transporters (opmQ, fpvA) establishes non-involvement of these candidate loci. Examination of pyoverdin polar accumulation in a model community and in a range of laboratory and natural species of Pseudomonas, including P. aeruginosa PAO1 and P. putida KT2440, confirms that the phenotype is characteristic of Pseudomonas.

Acculturation of Modern Civilization for Jungle Tribes in Southeast Asia: The Case Study Kubu Tribe

The Kubu tribe life is governed by the rules, norms and customs that apply in accordance with their belief. With these conditions, the problem which need to be discussed is how to acculturate modern civilization in the Kubu tribe. This research method is descriptive qualitative, the research intended to investigate the circumstances, conditions or other things that have been mentioned, the results of which are presented in the form of research reports. In this study, data were obtained from interviews with community leaders, traditional leaders, and the Kubu community. The results show that the implementation of acculturation of modern civilization in the Kubu Tribe is approaching the Kubu Tribe group, because they are still ashamed and inferior about mingling with the outside community. One strategy used by community leaders in introducing modern civilization to the Kubu tribe groups is approaching and providing counseling and model community life patterns as usual such as providing counseling in the fields of law, politic, education, religion, trading and introducing other community cultures. Unfortunately, the percentage of the allocation of funds for the empowerment of Kubu tribe is still relatively small compared to other social problems such as unemployment, homeless people and education problems.

Sosialisasi dan Edukasi Digital Marketing pada Komunitas BGBJ di Bantar Gebang Menghadapi Era 4.0

Tujuan dari kegiatan ini adalah untuk mengatasi masalah yang sedang berkembang di Bantar Gebang yaitu sebagai salah satu wilayah daerah Bekasi yang dijadikan sebagai tempat pembuangan sampah terakhir kawasan megapolitan Jabodetabek. Bantar Gebang selama ini dikenal sebagai daerah kumuh dengan kondisi perekonomian masyarakat bertaraf rendah (miskin). Sehingga muncul inisiatif anak-anak muda untuk membentuk suatu komunitas usaha kecil dengan memanfaatkan limbah kayu, plastik, dan kertas sebagai bahan dasar pembuatan produk kreatif, yaitu komunitas The Kingdom of BGBJ (Biji-Biji Bantar Gebang). BGBJ dibangun atas bantuan, dukungan, dan dedikasi para pengunjungnya. Komunitas ini menyediakan berbagai pelatihan, pendampingan, bantuan sandang, papan dan pangan untuk masyarakat yang tidak memiliki akses ke sumber daya ini. Dengan adanya kegiatan pemberdayaan ini, diharapkan dapat memberikan alternatif bagi masyarakat untuk memutus siklus kemiskinan serta menciptakan lingkungan yang sehat dan aman. Namun untuk dapat mengembangkan program ini, BGBJ mengakui bahwa sumber daya yang dimilikinya belum paham akan strategi pemasaran. Hal ini dapat dilihat dari kegiatan pemasarannya yang hanya dilakukan sebatas pada komunikasi offline yaitu Word of Mouth (WoM). Dengan permasalahan tersebut, maka dibuatlah suatu program pemberdayaan kepada peserta komunitas BGBJ dan masyarakat tentang pemahaman pemasaran digital (digital marketing) serta kegiatan pendukung lainnya yang bermanfaat. Metode pelaksanaan kegiatan dilakukan dengan pendekatan model community development yang diberikan dalam bentuk sosialisasi dan edukasi serta pelatihan dan pendampingan selama 3 bulan, terhitung dari bulan Juni – Agustus 2020. Hasil menunjukkan bahwa kegiatan pemberdayaan ini dapat diterima secara efektif dan para peserta dinilai sudah siap untuk beradaptasi menghadapi era 4.0. Hal ini dapat diukur berdasarkan survei yang dilakukan sebelum maupun setelah kegiatan pemberdayaan dilakukan. Meskipun demikian, terdapat evaluasi bahwa pengembangan program ini harus dilakukan secara berkelanjutan, dikarenakan masih terdapat sebagian peserta yang memerlukan arahan dan bimbingan lebih lanjut.Kata kunci: BGBJ; digital; media sosial; strategi pemasaran; 4.0.Socialization and Digital Marketing Education to the BGBJ Community in Bantar Gebang Facing Era 4.0 ABSTRACTThe purpose of this activity is to address a growing problem in Bantar Gebang, known as one of the Bekasi areas which is used as the final waste disposal site for the Jabodetabek megapolitan area. Bantar Gebang has been known as a slum area with low economic conditions (poor). So that the initiative of young people emerged to form a small business community by utilizing wood, plastic, and paper waste as basic materials for making creative products, they are The Kingdom of BGBJ (Bantar Gebang Seeds) Community. BGBJ was built on the help, support and dedication of its visitors. This community provides a variety of training, mentoring, clothing, shelter and food assistance for people who do not have access to these resources. With this empowerment, it is hoped that it can provide an alternative for the community to break the cycle of poverty and create a healthy and safe environment. However, to be able to develop this program, BGBJ admits that its resources do not understand the marketing strategy. This can be seen from its marketing activities which are only limited to offline Word of Mouth (WoM) communication. With these problems, an empowerment program was made for BGBJ community participants and the public regarding the understanding of digital marketing (digital marketing) and other useful supporting activities. The method of implementing activities is carried out with a community development model approach which is given in the form of socialization and education as well as training and mentoring for 3 months, starting from June - August 2020. The result showed that the empowerment activity can be accepted effectively, and the participants are considered ready to adapt to the 4.0 era. This can be measured based on a survey conducted before and after the empowerment activity was carried out. However, there is an evaluation that the development of this program must be carried out continuously, because there are still some participants who need further direction and guidance.Keywords: BGBJ; digital; social media; marketing strategy; 4.0.

Network Representation Learning Enhanced by Partial Community Information That Is Found Using Game Theory

Presently, data that are collected from real systems and organized as information networks are universal. Mining hidden information from these data is generally helpful to understand and benefit the corresponding systems. The challenges of analyzing such data include high computational complexity and low parallelizability because of the nature of complicated interconnected structure of their nodes. Network representation learning, also called network embedding, provides a practical and promising way to solve these issues. One of the foremost requirements of network embedding is preserving network topology properties in learned low-dimension representations. Community structure is a prominent characteristic of complex networks and thus should be well maintained. However, the difficulty lies in the fact that the properties of community structure are multivariate and complicated; therefore, it is insufficient to model community structure using a predefined model, the way that is popular in most state-of-the-art network embedding algorithms explicitly considering community structure preservation. In this paper, we introduce a multi-process parallel framework for network embedding that is enhanced by found partial community information and can preserve community properties well. We also implement the framework and propose two node embedding methods that use game theory for detecting partial community information. A series of experiments are conducted to evaluate the performance of our methods and six state-of-the-art algorithms. The results demonstrate that our methods can effectively preserve community properties of networks in their low-dimension representations. Specifically, compared to the involved baselines, our algorithms behave the best and are the runners-up on networks with high overlapping diversity and density.

Mega-Events and Rapid Transit: Evaluating the Canada Line 10 Years After Vancouver 2010

This article examines the Canada Line rapid rail transit project in Vancouver, British Columbia, a decade after its completion and the 2010 Winter Olympic Games for which it was accelerated. The case resides at the intersection of two project classes with well-documented patterns of underperformance: transit mega-projects and sporting mega-events. Beyond connecting a number of Vancouver 2010 venues, the Canada Line is notable for its use of a public-private partnership procurement (PPP) model, as well as the significant real estate development seen nearby. In particular, the article focuses on outcomes classified under three headings: procurement model, community impact, and land use impact. Prior to providing avenues for future research, this article finds that while the PPP model avoided substantial cost overrun risks, the lucrative operational concession was where the growth coalition pushing the project was able to make it sufficiently attractive for private partners, while externalizing cost on third-parties.
