Exploring Dynamics between Instructional Designers and Higher Education Faculty: An Ethnographic Case Study

This study concentrated on individual and team traits of an instructional design team in the presence of a robust relationship between the team members and faculty at a southeast state university in U.S.A. Three exploratory themes emerged from the interpersonal dynamics observed in this qualitative inquiry: (1) expertise, (2) work motivation, and (3) team culture. Preliminary results first suggested that professionalism with a mix of task mental models, assertiveness, and proactivity be implanted in the instructional designers. Then, instructional designers’ growth and survival needs allow for active learning and continuous reflection on curriculum development and instruction delivery in the e-Learning business. Next, loose-tight leadership, collective cognition, and collegiality are rooted in the team culture as the instructional design team becomes established. Implications and recommendations were discussed in the research study

ANALISA PENJADWALAN WAKTU PEMBANGUNAN LANJUTAN SMPN 38 LOK BAHU KOTA SAMARINDA

Since 2012, students of 38 Lok Bahu Junior High School must have a place at 027 Samarinda Elementary School. This was caused by the lack of funds from the Samarinda city government. However, it seems that the students of 38 Lok Bahu Junior High School can breathe a sigh of relief, because in mid 2018 the construction of the school which had stopped would be resumed. For this reason, the contractor in the implementation must be done well. Considering the previous project, the contractor appointed as the executor of this project advanced development project experienced delays in the realization of the project. This study will analyze the scheduling of time related to the optimal duration, critical trajectories and work networks that can be made in the advanced development activities of 38 Lok Bahu Junior High School using the CPM method, PERT and using Microsoft Project software. In the CPM method, the settlement time is around 266 days, while in PERT method, it is obtained 179 days of completion (June 2 - December 8, 2018), faster than 1 day from the plan schedule. Therefore, 179 days duration can be said as the optimal duration. The completion time with CPM and PERT methods is 87 days different. This is because the duration of activities in the PERT method obtained from interviews with the foreman, the duration is shorter or relatively fast than the plan, especially in supporting concrete structure work. Based on the calculations that have been made, the probability of project completion at 179 days is around 55.19%. The critical path in this project is A (Preliminary Work) - B (Supporting Concrete Structural Work) - C (Pair of Brick and Plaster) - D (Floor Work And Ceramic Wall) - F (Roof Frame Work) - G (Cover Wood And Ceiling Works) - H (Electrical And Mechanical) - K (Other Work)

Highly Efficient Midinfrared On-Chip Electrical Generation of Graphene Plasmons by Inelastic Electron Tunneling Excitation

Inelastic electron tunneling provides a low-energy pathway for the excitation of surface plasmons and light emission. We theoretically investigate tunnel junctions based on metals and graphene. We show that graphene is potentially a highly efficient material for tunneling excitation of plasmons because of its narrow plasmon linewidths, strong emission, and large tunability in the midinfrared wavelength regime. Compared to gold and silver, the enhancement can be up to 10 times for similar wavelengths and up to 5 orders at their respective plasmon operating wavelengths. Tunneling excitation of graphene plasmons promises an efficient technology for on-chip electrical generation and manipulation of plasmons for graphene-based optoelectronics and nanophotonic integrated circuits.Comment: 12 pages, 7 figure

An Extension Study: fMRI use to Distinguish Between Deception andGeneral Memory

The purpose of this study is to expand upon the findings published by Junhong Yu, Qian Tao,Ruibin Zhang, Chetwyn C.H. Chan, and Tatia M.C. Lee in their paper, “Can fMRI discriminatebetween deception and false memory? A meta-analytic comparison between deception and falsememory studies” by conducting a meta-analysis to compare brain activation between deceptionand general memory1 recollection (Yu et al., 2019). Meta-analyses compile fMRI results frommany individual studies with regard to a specific cognitive task into one, cumulative dataset. Themeta-analyses for this extension were compiled by Neurosynth using FMRIB Software Library(FSL) to measure the amount of brain activation corresponding to areas involved in bothdeception and memory in general (“Nipype: Neuroimaging in Python,” 2020). The purpose ofthis extension is to understand how general memory recollection might compare to deception.The prediction of this study is that by broadening the memory dataset to include data from falseand true memory, activation will be reported in more areas than those reported in Yu and hiscolleagues separate analysis of each kind of memory. This, in turn, should make it more difficultto differentiate deception from memory recollection when it is not known to be true or false.While Yu et al. 2019 concluded that areas associated with truthful memory and false memorywere both separately distinguishable from deception, the results found in this study indicate thatactivation involved with general memory was distinguishable from deception only in theprecuneus and cingulate gyrus

Cord blood versus age 5 mononuclear cell proliferation on IgE and asthma

Abstract Background Fetal immune responses following exposure of mothers to allergens during pregnancy may influence the subsequent risk of childhood asthma. However, the association of allergen-induced cord blood mononuclear cell (CBMC) proliferation and cytokine production with later allergic immune responses and asthma has been controversial. Our objective was to compare indoor allergen-induced CBMC with age 5 peripheral blood mononuclear cell (PBMC) proliferation and determine which may be associated with age 5 allergic immune responses and asthma in an inner city cohort. Methods As part of an ongoing cohort study of the Columbia Center for Children's Environmental Health (CCCEH), CBMCs and age 5 PBMCs were cultured with cockroach, mouse, and dust mite protein extracts. CBMC proliferation and cytokine (IL-5 and IFN-γ) responses, and age 5 PBMC proliferation responses, were compared to anti-cockroach, anti-mouse, and anti-dust mite IgE levels, wheeze, cough, eczema and asthma. Results Correlations between CBMC and age 5 PBMC proliferation in response to cockroach, mouse, and dust mite antigens were nonsignificant. Cockroach-, mouse-, and dust mite-induced CBMC proliferation and cytokine responses were not associated with allergen-specific IgE at ages 2, 3, and 5, or with asthma and eczema at age 5. However, after adjusting for potential confounders, age 5 cockroach-induced PBMC proliferation was associated with anti-cockroach IgE, total IgE, and asthma (p < 0.05). Conclusion In contrast to allergen-induced CBMC proliferation, age 5 cockroach-induced PBMC proliferation was associated with age 5 specific and total IgE, and asthma, in an inner-city cohort where cockroach allergens are prevalent and exposure can be high
