An Awareness Raising System to Support Cross-department Coordination in Matrix Organizations

Collaboration in matrix organizations brings challenges involving decision support, communication, knowledge sharing, and, mainly, awareness. By implementing Lean Principles, organizations improve different aspects of service providing. However, the broad view of clients and the detailed knowledge regarding clients' business are reduced when a team serves different clients in a matrix structured service provider. This work presents a system developed after a 30 months long investigation of daily practices and needs of workers of an IT (Information Technology) service delivery factory. The developed system aims at raising awareness and supporting workers communication. The system's conception, design, and development, counted on interviews, focus groups, and usability test. Along the manuscript, results from informal activities are presented, while the formal user test is detailed in the evaluation section. Our collaboration is twofold: (1) in-depth description of cross-department coordination challenges and mechanisms in a very-large IT service delivery organization; (2) presenting the developed system and the rational behind it. We expect researchers and practitioners working on similar problems to benefit from the research detailed in this work.
ICT for data collection and monitoring and evaluation : opportunities and guidance on mobile applications for forest and agricultural sectors

Tracking progress in sustainable agriculture and forest management is challenging: distances are long, populations are sparse, interventions range from policies to crop and livestock practices, and the voice of the farmer is critical for success. Recent approaches focusing on climate impacts and land use pressures (climate-smart agriculture and landscape approach) add to the complexity and require efficient data collection and analysis methods. The systemization of information and communication technology (ICT) in the monitoring and evaluation (M and E) process enables accountability- from field staff to regional and central governments and development partners. The leapfrog effects of ICT have increased access to quality information, eased knowledge sharing among practitioners and resource-constrained governments, and created opportunities to improve accountability. The expansion of ICT has also made the work of development practitioners easier and more accurate. In some regions there are already more mobile phone subscriptions than people, and even internet access has become more common. This report identifies where ICT has expanded the capacity to perform good M and E and, more importantly, it identifies where it has not. It identifies where and how it can expand data collection and M and E, but also why and how technology is not a replacement for human agency and involvement in analysis and interpretation tasks. This report seeks to present solutions to some of the questions concerning data collection and M and E. It is designed to be an operational piece that addresses how governments and practitioners can use ICT to improve their data collection and M&E efforts in rural development projects. The first section gives overview. The second section of the report focuses on the most important aspect of ICT use: articulating the needs of the project and users. The third section provides an overview of five models currently used to implement and integrate information technology into M and E efforts. The crux of the report centers on choosing the right product or set of products for the project, and it includes cross-comparative guidance on application features such as data validation, offline capacity, dashboards, and built-in analytics in section four. The service design section deals with issues inherent to the provision of public services, such as how to provide appropriate incentives for the participation necessary to sustain the program and why post-data collection efforts are critical to success is discussed in section five. Along with these practical approaches to deploying ICT, the report describes five case studies on mobile-based data collection in the agriculture and forest sectors in section six. The conclusion section follows the case studies in section seven.
High Incidence of Implant Failure Happened Using Anterior-posterior Screws for the Fixation of Tibial Posterior Pilon Fracture.

Objective：To explore the mechanism of posterior pilon fracture with different proportion of the medial malleolus involved and evaluate clinical outcomes of anterior-posterior screws fixation.Methods: Patients admitted to our hospital with diagnosis of tibial posterior Pilon fracture were identified from January 2014 to January 2018. Mechanism from medical history, proportion of the medial malleolus involved (not involved/partial involved /total involved) from axial CT sacn were recorded to figure out the mechanism . Burwell—Charnley radiographic criteria of reduction, American orthopaedic Foot＆Ankle society ankle-hindfoot scale at 12 month follow-up were recorded to evaluate the curative effect of anterior-posterior screws fixation.Result: Sixty-nine patients were identified in this retrospective study. 43 males and 26 females were included, with mean age 46.9 years old（range, 21-76 years）.

Plant growth promoting rhizobacteria (PGPR) as eco-friendly alternatives for management root-knot nematodes, Meloidogyne spp. on tomato plants.

Plant Growth Promoting rhizobacteria (PGPR) are a various group of bacteria that could be create in the rhizosphere, at root surfaces and in association with roots. PGPR can be used as bio-control agents. The objective of this study was to assess four different bacterial strains i.e. Pseudomonas fluorescens, Azospirillum brasilense, Azotobacter chroococcum and Bacillus megaterium against Meloidogyne spp at three different incubation times i.e. 24, 48, 72 and 168 hrs under laboratory conditions. Furthermore, the strains were evaluated at different application times i.e. (one week before, at the same time and one week after nematode inoculation) as biocontrol agents against Meloidogyne spp. on tomato plants in pots experiments. In vitro results revealed that the highest inhibition percentage in egg hatching and larvae mortality recorded after 168 hrs with B. megaterium by 17.3% and 92%, respectively. Greenhouse, results cleared that all evaluated bacterial strains at all different application times had the potentiality in Meloidogyne spp. parameters reduction i.e. (number of galls, egg masses, females/root system and juveniles in soil) and the reproduction to a huge extent compared to treated plants with nematode alone. Plants inoculated with B. megaterium achieved also the highest increases in shoot and ISSN 2537_ 0715 IJSRSD (2021): Volume 4, Issue 2, August 2021 International Journal of Scientific Received: June 2021, Accepted: July 2021 Research and Sustainable Development Page 2 of 31 root lengths and weights when applied one week before nematode inoculation by 213.3, 175, 180 & 291.3%, respectively compared to the other application times. Also it the highest values of ch.a, chl.b, total chlorophyll and carotenoids by 1.0, 0.75, 1.75 and 0.78 mg/ g.f. w. , respectively recorded with B.megaterium when applied one week before nematode inoculation after 30 days from transplanting. Plants inoculated with A. chroococcum recorded the lowest photosynthetic pigments. Peroxidase (POX) and polyphenol oxidase (PPO) were increased with all bacterial strains treatments. The significant increase of dehydrogenase activity and total count of bacteria of all different bacterial strains observed when applied at all three application times were compared to plants infected with nematode alone.
Systems Engineering for Contingency Basing

Abstract : This research focused on specific aspects of Tactical Small Unit-Contingency Basing (TSU-CB), as a force projection platform and a potential means to address the interrelated individual Soldier and TSU load (cognitive and physical) using methods and tools developed for systems engineering. The research task is to develop a set of interrelated processes, mechanisms, and tools to capture, explain, and manage the complex operational and system interaction posed by the dynamic nature of the TSU operations, along with a means to measure progress. The TSU exhibits a complex, pluralistic, set of requirements across a number of factors ill-suited to standard system engineering practices. Novel means to optimize TSU-CB need to be considered.
ELICIT Multistrike: Adapting ELICIT to Study Collaboration and Decision Making for Time-Sensitive Strikes

Abstract : Long distance collaboration is an increasingly important aspect of command and control (C2). It is not always possible, or desirable, for all relevant experts and decision makers to be collocated during time-sensitive missions. However, geographic distance and the associated problems of narrow communications bandwidth, lack of trust, and biased attention have not always been taken into account in the design of C2 systems. Time pressure and high-risk decisions exacerbate the problems of coordination and trust over long distance; these are unfortunately two of the defining features of many C2 tasks involving time-sensitive strikes. In order to more closely examine high-risk decisions under time pressure, the Experimental Laboratory to Investigate Collaboration, Information-sharing, and Trust (ELICIT; Ruddy, 2007), was altered to emphasize these aspects. The resulting environment, ELICIT Multistrike, uses the ELICIT environment as the information-sharing and collaboration tool, a text messaging system as the communication tool, and a multi-decision point, time-sequenced factoid set. This paper describes the design features and pilot testing of ELICIT Multistrike; examines the differences from the well-known original ELICIT task; and discusses the design of an ELICIT Multistrike experiment to demonstrate the ability to use the ELICIT framework to study collaboration and decision making for time-sensitive strikes.
Wavelength controllable device for simultaneous generation of surface plasmon polariton Bessel-like beams and bottle beams

Realizing multiple beam shaping functions in a single plasmonic device is the key to realizing photonic integration. Surface Plasmon Polariton (SPP) Bessel-like Beams and Bottle Beams have potential applications in nanophotonics, especially in near-field optical trapping, micro-manipulation, and on-chip interconnect circuits. Thus, it is very interesting to find new approaches for simultaneous generation of surface plasmon polariton Bessel-like beams and bottle beams in a single photonic device. The wavelength-manipulated Bessel SPP beam and Bottle beam emitters devices are composed of four and five compact coupling elements with a specific spatial distribution, respectively. Besides, as the wavelength of the incident light is changed, the generated Bessel-like SPP beam and SPP Bottle beam can be directionally excited on one side of the transmitter and the launching direction can be dynamically selected. The design scheme of the proposed device provides a new means for constructing plasmonic devices with multiple beam shaping functionalities.
History of the Electric Automobile: Hybrid Electric Vehicles

Sections include: the research undertaken in previous centuries which led to the first electric vehicle in 1881; historical efforts to overcome the limited range of electric vehicles (including examinations of the round spring, the Stirling engine, the flywheel, solar cells, and more); the growing interest in races featuring hybrid electric vehicles (including the Australian World Solar Challenge races, and the American Tour de Sol).
Development of synthesis method of functional diagnostic system for thrusters of underwater vehicles

This paper presents a new synthesis method of functional diagnostic system for thrusters of underwater vehicles (UVs). This system provides detection, localization and identification of minor faults in thrusters of the UV. Proposed method involves two main stages. At the first stage, a bank of diagnostic observers is built to detect and localize the emerging faults. At the same time, each observer is constructed according to a special procedure in such a way as to be sensitive to a different set of the possible faults. At the second stage, the additional observers working in a sliding mode regime are synthesized in order to accurately estimate error values in signals obtained from the UV thruster sensors, and to evaluate deviations of the thruster parameters from their nominal values due to the faults. The results of the simulation show the efficiency and high quality of all synthesized observers.
A Study on the Asymmetric Preswirl Stator System

This paper deals with both experimental and theoretical methods for performance prediction of asymmetric stater propulsion systems which have been used for the purpose of recovery of a propeller slipstream rotational energy due to a stator located in front of the propeller. Using the developed computer code based on the lifting surface theory, theortical investigation on the interaction between the stator and the propeller is provided in order to obtain general insight on the performance characteristics of the propulsion systems in uniform and non-uniform flow. Such theoretical calculations have end agreements with model Inset results. The asymmetric stator would give an efficiency gain of about 6% to the compound propulsor system compared with the single propeller system.
Resilience, poverty and development

Resilience has become prominent in academia where it is used as a central framework in disciplines such as ecology, climate change adaptation or urban planning. Policy makers and international development agencies also increasingly refer to it. The objective of this paper is to assess the advantages and limits of resilience in the context of development. Although the review highlights some positive elements—for example, the ability to foster an integrated approach—it also shows that resilience has important limitations. In particular, it is not a pro-poor concept, in the sense that it does not exclusively apply to, or benefit, the poor. As such, resilience building cannot replace poverty reduction.

INFLUENCE OF TRANSITION LOCATION ON AIRFOIL DRAG

A comparison of predicted and measured laminar-turbulent transition on the airfoil is presented. The MSES code is used for a prediction. The experimental data are taken from an experiment of W. Würz. Comparison of calculated results with measured data shows that the envelope of calculated individual frequencies coincides well with measured data in the transitional region for the attached boundary layer and for the separated laminar shear layer. For minimum drag, the laminar flow should be as long as possible and the shape parameter of the boundary layer at the transition should not exceed the value of 3.8. The optimum value of the shape parameter is 3.65 at Reynolds numbers from 1 to 2 million.
Ganglion Cell-Inner Plexiform Layer Thickness is Associated with Persistently Cognitive Decline -The Rugao Longevity and Aging Study

Background: The simple, convenient and well-validated biomarkers are imperative for detection of cognitive decline (CD). The powerful evidence is lacked for verifying the reliability and clinical utility of retinal biomarkers for detection of CD with repeated assessments. To investigate the association of retinal thickness with CD using repeated assessments. Methods: This study included 446 older adults with three-time repeated assessments of cognitive function during 5-years follow-up. Retinal thickness measured on spectral-domain optical coherence tomography. Logistic regression models were conducted to analyze the association of retinal thickness with cognitive function. Results: According to cognitive status in three assessments, individuals were categorized into consistently normal cognition groups (N = 159), persistently CD groups (N = 134), progressed to CD groups (N = 70), and reverting or fluctuating CD groups (N = 83). Thinner ganglion cell-inner plexiform layer (GC-IPL) was associated with persistently CD (odds ratio [OR] per 1-μm decrease: 1.09, 95% confidence interval [CI], 1.02-1.18; per standard deviation [SD] decrease: 1.78, 95%CI, 1.04-3.19) rather than progressed to CD, reverting or fluctuating CD. No significant relationship was found between retinal nerve fiber layer and any CD subgroups (p > 0.05). Conclusions: Thinner GC-IPL was associated with persistently CD, suggesting retinal neurodegeneration may be a promising biomarker for persistently CD. Further studies, including both longitudinal and repeated measurements of retinal layer thickness and cognitive function, are needed to assess the possibility of retinal thickness as a biomarker for persistent CD.
Performance and confidence levels of students entering physics at three South African Universities

A test instrument, made up of 25 items, derived from existing standardized tests from literature, was used to probe for the students' knowledge and understanding of basic mechanics concepts, as well as the confidence in the correctness of their answers. The test was administered to 982 first entering physics students; enrolled at three South African universities, at the beginning of the year before any formal instruction could take place. Data collected for this study included students' responses from multiple-choice questions and open-ended explanations to their chosen answers. The analysis of the multiple-choice responses and the written explanations revealed the existence of alternative conceptions among students and that the students' accuracy of judgment about their knowledge and understanding of basic mechanics concepts is different among the different cohorts. Physics education research, has over a number of years, revealed that students have alternative conceptions about physical processes. These alternative conceptions are accumulated from the students' past personal experiences, interactions with people around them and the environment they live in. It was found from the study that the strength of the known alternative conceptions differs among the different cohorts. There are those alternative conceptions that are easier to correct with sound teaching. These alternative conceptions exist mostly in worst performing cohorts and less so in the best performing cohorts. There are those alternative conceptions that persisted despite better teaching. These alternative conceptions are found in all the cohorts.
Control Interface for Driving Interactive Characters in Immersive Virtual Environments

Abstract : The effectiveness of training Soldiers in immersive 3D virtual environments is currently limited by character control interfaces that require users to learn actions, for example moving a joystick or pressing a button, that do not necessarily enhance the user's physical performance in equivalent real world tasks and situations. In order to address this need, an advanced man/machine user interface has been developed utilizing inertial position, orientation, ultrasonic range and foot force sensors that allows users to naturally control interactive character movements using sensorimotor responses that closely resemble the tasks and actions performed in the real world. Known as a Virtual Locomotion Controller (VLC), this paper describes the VLC system architecture, control logic and associated sensor processing and the simulation environment used to determine the feasibility of the approach.
