Planning and Organizing: Determinants of Job Performance among Football Club Coaches in F.C.T. Abuja

The study focused on planning and organizing as determinants of job performance among football club coaches in F.C. T. Abuja. The study ascertained the extent to which planning and organizing functioned as determinants of job performance among football club coaches in Abuja as perceived by coaches and sports administrators in the area. The sample for this study was made up of one hundred and thirty (131) coaches and sports administrators. The instrument for data collection is the researcher-designed questionnaire on administrative tasks determinants otherwise called (QATD). The questionnaire is divided into two sections, A&B. Section A, consists of one item, demanding the personal data of the respondents. Section B, composed of planning and organizing as the determinants job performance. The data collected was subjected to descriptive statistics of mean and standard deviation and inferential statistic of student ttest. The analysis showed that both Coaches and Sports Administrators agreed that planning and organizing to a high extent determine the job performance of Coaches in FCT, Abuja.
Analysis of negative differential resistance in the I-V characteristics of shorted-anode LIGBT's

The physical mechanism responsible for the negative differential resistance (NDR) in the current-voltage characteristics of the shorted anode lateral insulated gate bipolar transistor (SA-LIGBT) is explained through two-dimensional numerical simulation. The NDR regime is an inherent feature of all SA-LIGBTs, and results from the two different conduction mechanisms responsible for current flow in the device. These conduction mechanisms are minority-carrier injection and majority-carrier flow. Since both the anode geometry and the doping profile control the onset and the degree of minority-carrier injection, the effect these parameters have on the NDR is investigated. A simple lumped-element equivalent model of the SA-LIGBT allows qualitative predictions to be made on how changes in the device geometry and doping profiles influence the NDR regime. It is shown that conductivity modulation is a necessary but not sufficient condition for the occurrence of negative resistance in SA-LIGBT devices. Also required is a large voltage drop in the high-resistivity drift region before conductivity modulation is initiated. This causes small changes in the anode current level, greatly decreasing the total resistance across the drift region. >
Research on the Influence of Intergenerational Support on the Self-evaluated Health of the Left-behind Elderly in Rural Areas

With the purpose of studying the impact of intergenerational support on the health of left-behind elderly in rural China, using the method of orderly logistic regression, the three dimensions of intergenerational support (economic support, life care, and emotional support) are used to analyze the effects of self-evaluation of the health of left-behind elderly in rural areas. Studies have found that children’s financial support to their parents is conducive to the health of left-behind elderly in rural areas; child care is not conducive to the health of leftbehind elderly in rural areas, and taking care of grandchildren has a positive impact on the health selfevaluation status of rural left-behind elderly; children’s emotional support has a positive impact on the health of rural left-behind elderly. Therefore, the following suggestions are put forward: strengthen children’s awareness of supporting the elderly through publicity, education, and guidance; increase the use of mobile phones and other electronic products by the elderly to keep in touch with their children and enhance mutual emotion; to make the elderly dependable, we must vigorously develop the long-term care insurance system.
Effects of managerial ties and trust on supply chain information sharing and supplier opportunism

Managerial ties and trust are important factors in facilitating collaboration and reducing opportunistic behaviour. There is, however, a lack of empirical evidence on how these relational factors influence the sharing of information among supply chain partners. For example, do stronger managerial ties help to improve supply chain information sharing (SCIS) and reduce supplier opportunism? To what extent SCIS is influenced by managerial ties and trust? How do managerial ties interact with trust in influencing SCIS? Using data from 272 Chinese manufacturers, this paper examines the impact of managerial ties and trust on SCIS and supplier opportunism. The results show that, through trust managerial ties can significantly influence the extent of information sharing and the quality of the information shared. Managerial ties also have a direct impact on the extent of information sharing, but not on the quality of the information shared. The main implication for management practice is that the quality of the information shared – rather than the extent of information sharing – should be seen as the main leverage in reducing supplier opportunism.
It’s Time to Shift the Paradigm: Translation and Clinical Application of Non-αvβ3 Integrin Targeting Radiopharmaceuticals

Simple Summary Cancer cells often present a different set of proteins on their surface than normal cells. This also applies to integrins, a class of 24 cell surface receptors which mainly are responsible for physically anchoring cells in tissues, but also fulfil a plethora of other functions. If a certain integrin is found on tumor cells but not on normal ones, radioactive molecules (named tracers) that specifically bind to this integrin will accumulate in the cancer lesion if injected into the blood stream. The emitted radiation can be detected from outside the body and allows for localization and thus, diagnosis, of cancer. Only one of the 24 integrins, the subtype αvβ3, has hitherto been thoroughly investigated in this context. We herein summarize the most recent, pertinent research on other integrins, and argue that some of these approaches might ultimately improve the clinical management of the most lethal cancers, such as pancreatic carcinoma. Abstract For almost the entire period of the last two decades, translational research in the area of integrin-targeting radiopharmaceuticals was strongly focused on the subtype αvβ3, owing to its expression on endothelial cells and its well-established role as a biomarker for, and promoter of, angiogenesis. Despite a large number of translated tracers and clinical studies, a clinical value of αvβ3-integrin imaging could not be defined yet. The focus of research has, thus, been moving slowly but steadily towards other integrin subtypes which are involved in a large variety of tumorigenic pathways. Peptidic and non-peptidic radioligands for the integrins α5β1, αvβ6, αvβ8, α6β1, α6β4, α3β1, α4β1, and αMβ2 were first synthesized and characterized preclinically. Some of these compounds, targeting the subtypes αvβ6, αvβ8, and α6β1/β4, were subsequently translated into humans during the last few years. αvβ6-Integrin has arguably attracted most attention because it is expressed by some of the cancers with the worst prognosis (above all, pancreatic ductal adenocarcinoma), which substantiates a clinical need for the respective theranostic agents. The receptor furthermore represents a biomarker for malignancy and invasiveness of carcinomas, as well as for fibrotic diseases, such as idiopathic pulmonary fibrosis (IPF), and probably even for Sars-CoV-2 (COVID-19) related syndromes. Accordingly, the largest number of recent first-in-human applications has been reported for radiolabeled compounds targeting αvβ6-integrin. The results indicate a substantial clinical value, which might lead to a paradigm change and trigger the replacement of αvβ3 by αvβ6 as the most popular integrin in theranostics.
Analytical and experimental study of gain enhancement in antenna arrays covered with high index metamaterial superstrate

Antenna arrays are used in communication applications where directive beams are required.In this article, we show analytically and experimentally that the gain of an antenna array can be further increased by covering it with a high refractive index superstrate. For the experimental demonstration, a corporate‐fed 4 × 1 microstrip patch array is fabricated and the electromagnetic pattern measurements are performed on the array covered with a magneto‐dielectric metamaterial. A fast analytical solution for the radiation fields of the superstrate‐covered microstrip antenna array is also proposed. The analytical solution is based on the reciprocity theorem in conjunction with the transmission line analogy and the cavity model. The artificial superstrate is designed using broadside coupled split ring resonator inclusions and is placed at approximately one‐tenth of a wavelength apart from the patch array operating at 2.2 GHz. A directivity increase of about 3.4 dB is achieved after covering the antenna array with the engineered magnetic superstrate. A comparison of results using the analytical model, the full‐wave simulations and measurements show good agreement. The proposed analytical formulation requires only 2.5% of the time required by full‐wave analysis. The superstrate‐based directivity enhancement method can be used in commercial antennas to combat some of the downsides of the existing systems such as gain decrease due to surface waves and dielectric losses. © 2012 Wiley Periodicals, Inc.

A parallel-connected single phase power factor correction approach with improved efficiency

In this paper, a new parallel-connected single phase power factor correction (PFC) topology using two flyback converters is proposed to improve the output voltage regulation with simultaneous input power factor correction and control. This approach offers lower cost and higher efficiency by parallel processing of the total power. Flyback converter-I primarily regulates output voltage with fast dynamic response and processes 55% of the power. Flyback converter-II with AC/DC PFC stage regulates input current shaping and PFC, and processes the remaining 45% of the power. This paper presents a design example and circuit analysis for 200 W power supply. A parallel-connected interleaved structure offers smaller passive components, less losses even in continuous conduction inductor current modes, and reduced volt-ampere rating of DC/DC stage converter. TI-DSP, TMS320LF2407, is used for implementation. Simulation and experimental results show the performance improvement.
Another deficient monsoon 2004 - A comparison with drought year 2002 and possible causes

The rainfall over India as a whole during the summer monsoon season of 2004 was deficient with –13% below normal. Earlier in 2002, India has faced another worst situation when large-scale drought occurred and all India rainfall was below –19%. In the present study, we have compared briefly salient observational features of both the monsoons to find out their distinct characteristics. Comparisons show appearance of many similar as well as contrasting features. Though, both seasons were deficient, their dates of onset of monsoon over Kerala were either before or near the normal date. Progress up to central India was also normal in both the seasons. While Indian Summer Monsoon Rainfall (ISMR) during June was good, a few longest stagnation periods during advancing stage in July of both the years made unexpected delay of monsoon in covering entire India. Rainfall of July also suffered the most in both the seasons with a record lowest ISMR in 2002. Not a single depression formed in 2002 while in 2004, their frequency was less than half of normal. Analysis of other large-scale monthly anomalous ocean and atmospheric conditions over Indo-Pacific region including El-Nino conditions confirms that ENSO and Equatorial Indian Ocean Oscillation or EQUINOO have caused drought in July 2002, but not in July 2004. This is because very high typhoon formation and their recurvature with significantly higher than normal convection over northwest Pacific associated with record lowest ISMR in July, 2002 in contrast to occurrence of deficient ISMR in July 2004 which was associated with few typhoon formation and less convection. Also in 2002, Indian region was happened to fall exactly under the subsidence branch of Walker circulation with ascending branch over the western Pacific in the season in contrast to 2004, when subsidence was observed to be both over large part of western Pacific and adjoining Indian region.
A decentralised multi-objective scheduling methodology for semiconductor manufacturing

This paper presents a decentralised multi-objective scheduling methodology for semiconductor manufacturing. In this methodology, a new classification method is designed based on utilisations and entropies in order to decentralise global objectives into local ones of work stations. Then, a decentralised multi-objective scheduling policy is proposed to control virtual production lines (VPLs) and machine workload. Results of numerical experiments show that the proposed methodology outperforms common rule-based scheduling policies and a compound scheduling strategy.
Analysis of axial‐induction‐based wind plant control using an engineering and a high‐order wind plant model

Wind turbines are typically operated to maximize their performance without considering the impact of wake effects on nearby turbines. Wind plant control concepts aim to increase overall wind plant performance by coordinating the operation of the turbines. This paper focuses on axial-induction-based wind plant control techniques, in which the generator torque or blade pitch degrees of freedom of the wind turbines are adjusted. The paper addresses discrepancies between a high-order wind plant model and an engineering wind plant model. Changes in the engineering model are proposed to better capture the effects of axial-induction-based control shown in the high-order model. Copyright © 2015 John Wiley & Sons, Ltd.
Perfect Difference Network for Network-on-Chip Architecture

†† Summary Network-on-Chip (NoC) is a new paradigm for designing core based System-on-Chip. Network-on-Chip has been proposed as a solution for addressing the design challenges of future high performance nanoscale architectures. Innovative system-level performance models are required for designing NoC based architectures. In this paper, we discuss the possibility of achieving the energy-aware NoC architecture based on the mathematical notion of Perfect Difference sets (PDS). We present the analytical energy model for NoC platform using Perfect Difference Network (PDN). The proposed energy model is then validated against the simulation results obtained with Inter-tile link geometry and PDN circular geometry for NoC architecture. Significant energy saving is achieved for Perfect Difference Network with circular geometry in comparison with inter-tile geometry of NoC architecture on the basis of our proposed energy model.
A Universal Test Fixture For Characterizing MM-Wave Solid State Devices Using A Novel Deembedding Procedure

The design and evaluation of a novel fixturing technique for characterizing mm-wave solid state devices, including monolithic microwave integrated circuits, is presented. The technique utilizes a cosine tapered ridge guide fixture and a one-tier deembedding procedure to provide accurate and repeatable device level data. Advanced features include "nondestructive" testing, full waveguide bandwidth operation, a high degree of universalism, and rapid yet repeatable chip-level characterization. Furthermore, only one set of calibration standards is required regardless of device geometry.
A directive dual‐band and dual‐polarized antenna with zero index metamaterial

A novel directive dual‐band and dual‐polarized microstrip antenna with ZIM is presented. An averaging effect over constituent materials of the metamaterial structure yields an effective permittivity that approaches zero at dual band with different polarizations, and then it results in a metamaterial with zero index of refraction and the radiation energy of this antenna is congregated. The experimental results show that this method is effective, and this structure can greatly increase the gain at dual frequencies. © 2008 Wiley Periodicals, Inc.

Results: The networked management learning business simulator improves the systems dynamics models from MIT and the Systems Dynamics Society by at least two orders of magnitude. Results indicate that participants move from an individualistic competitive stance to a collaborative team-based solutions focus to threats and problems faced by their supply chain during increasingly challenging business simulations.
Opportunities and Problems of the Consensus Conferences in the Care Robotics

Care robots represent an opportunity for the health domain. The use of these devices has important implications. They can be used in surgical operating rooms in important and delicate clinical interventions, in motion, in training-and-simulation, and cognitive and rehabilitation processes. They are involved in continuous processes of evolution in technology and clinical practice. Therefore, the introduction into routine clinical practice is difficult because this needs the stability and the standardization of processes. The agreement tools, in this case, are of primary importance for the clinical acceptance and introduction. The opinion focuses on the Consensus Conference tool and: (a) highlights its potential in the field; (b) explores the state of use; (c) detects the peculiarities and problems (d) expresses ideas on how improve its diffusion.
COllective INtelligence with task assignment

In this paper we study the COllective INtelligence (COIN) framework of Wolpert et al. for dispersion games (Grenager, Powers and Shoham, 2002) and variants of the EL Farol Bar problem. These settings constitute difficult MAS problems where fine-grained coordination between the agents is required. We enhance the COIN framework to dramatically improve convergence results for MAS with a large number of agents. The increased convergence properties for the dispersion games are competitive with especially tailored strategies for solving dispersion games. The enhancements to the COIN framework proved to be essential to solve the more complex variants of the El Farol Bar-like problem.

An order release mechanism for a flexible flow system

Order release is where orders are released to the shop floor for processing. An Order Release Mechanism (ORM) can control order release, such that orders are selectively released so as to improve shop management and performance. This paper reports on the development of an ORM for a specific Flexible Flow System (FFS), where the primary criterion in running the system is flow time. The ORM determines what order to release when, and makes the routeing decisions for each order. Using a simulation model, the performance of the FFS with the ORM was compared to present practice without an ORM and an ‘off-the-shelf’ ORM from the literature, namely CONWIP. It is found that the ORM not only improves the mean time that orders spend in the shop under all load conditions, but also reduces the variance of this measure. It would be expected that the total time that orders spend in the system increases with the ORM, at least compared to immediate release, but at high load levels it is found that this measure also decrea.
