Productivity and new work organization. An assessment of the literature

The paper presents a literature review on the characteristics of new forms of work organization, with respect to traditional Taylor-Fordist organization, and their impact on productivity. The analysis is developed primarily with reference to the world of manufacturing firms, focusing particularly on the roles established by new organizational design, new work practices, new technologies (ICT), industrial relations and their complementarities. The new organizational configuration that effectively emerges from the literature is characterized by a set of innovative bundles of work practices made up not only of different ‘ingredients’ but also of the different weights of each ingredient. Hence, the employer and/or manager has two levers to pursue efficiency and performance: ingredients and their indefinable combination. The superior performance of this new work organization ‒ in line with lean production paradigm (sometime called World Class Manufacturing - WCM) – is clearly acclaimed by a number of econometric studies despite the fact that some methodological questions remain open, which unless resolved will not aid in overcoming theresistance of sceptics, be they academics, practitioners, managers, trade union leaders or policy makers.
Exploration of Neural Structures for Dynamic System Control

Biological neural systems are powerful mechanisms for controlling biological systems. While the complexity of biological neural networks makes exact simulation intractable, several key aspects lend themselves to implementation on computational systems. This thesis constructs a discrete event neural network simulation that implements aspects of biological neural networks. A combined genetic programming/simulated annealing approach is utilized to design network structures that function as regulators for continuous time dynamic systems in the presence of process noise when simulated using a discrete event neural simulation. Methods of constructing such networks are analyzed including examination of the final network structure and the algorithm used to construct the networks. The parameters of the network simulation are also analyzed, as well as the interface between the network and the dynamic system. This analysis provides insight to the construction of networks for more complicated control applications.
Comparing Organic vs. Handoff UAV Support to the Maneuver Company

Abstract : The US Army has plans to deploy a dedicated Unmanned Aerial Vehicle (UAV) system at every echelon in order to provide responsive support to the battlefield commanders. However, there are disadvantages to fielding such a large number of different and separately controlled vehicles. This research addresses one key part of this issue of selecting the right mix of UAV systems: How shall a company be supported? We consider two alternatives for the company commander, loosely based on systems currently under development: (1) the "Organic" system, which consists of two vehicle-transported VTOL vehicles of ~50 kg each assigned to each company and flying missions when needed; and (2) the "Handoff" system, a 100-200 kg vehicle in the air constantly during operations, maintained and launched at the battalion level, but handed off as needed to the companies, which have Level IV control capability. We focus on performance measures that are strongly affected by the architecture and on finding closed-form approximations that allow extensive sensitivity analysis. We use high-level queuing and Markov chain models to estimate performance. We find that under some circumstances maneuver companies are better served by the "Handoff" system. We also identify performance and scenario parameters that have a strong effect on this and consequently deserve more study. This inquiry originated as a group project given to several teams of cadets taking SE450: Project Management and System Design. Though it was originally purely an academic exercise, the methods and results of several of the teams were of great interest. The authors were inspired to develop the best of the cadets' ideas, adding their own contributions to produce this work. We include in this report some remarks on how well the project worked in helping the cadets understand how to approach a complex systems engineering problem typical of those faced by the Army.
Safe Distances From a High-Energy Capacitor Bank for Ear and Lung Protection

Abstract : High-energy capacitor banks may have a significant amount of residual energy after a test or malfunction. This presents distinct hazards from shock, arc flash, projectile, and lung/ear/eye when the capacitor bank is to be manually rendered safe. Although standard operating procedures address most of these hazards, the danger to the ear and lung from the over-pressure of an arc blast has not been satisfactorily established. This lung and ear danger is addressed in this report, along with proposed mitigation techniques.
Investigations on Axial Compressor Cascades with Aspiration on Blades and Hub

This document presents an overview of the investigations performed within the project NEWAC on the application of active flow control by aspiration to axial compressors. It is based on the measurements performed on different annular cascades, tested in the non rotating annular wind tunnel of EPFL in cooperation with the project partner ECL. In parallel to these measurements, both predictive and a-posteriori CFD simulations were performed by the project partners at SNECMA and ONERA. Several configurations were investigated in the annular wind tunnel with and without aspiration, on the hub or/and on the blades. For each cascade configuration, different inlet flow conditions were applied for several aspiration ratios. This yielded a large database of results that allows detailed analysis of the various influences by cross comparison of different cases. The applied measurement techniques included five-hole-probe measurements, Laser Doppler Velocimetry as well as pressure tap measurements on hub, casing and blades. The investigations gave an insight into the fluid mechanisms involved with the application of aspiration on blades and hub of an axial compressor rotor geometry. Since the flow structure resulting from simulations and experiments appreciably agree, the simulations significantly support the understanding of the flow mechanisms involved with the application of aspiration to the cascades. A selection of results, comparisons and conclusions is presented.
Tweak the tweet: Leveraging microblogging proliferation with a prescriptive syntax to support citizen reporting

In this paper, we propose a low-tech solution for use by microbloggers that could enhance their ability to rapidly produce parsable, crisis-relevant information in mass emergencies. We build upon existing research on the use of social media during mass emergencies and disasters. Our proposed intervention aims to leverage the affordances of mobile microblogging and the drive to support citizen reporting within current behavioral Twitter-based microblogging practice. We introduce a prescriptive, tweet-based syntax that could increase the utility of information generated during emergencies by gently reshaping current behavioral practice. This offering is grounded in an understanding of current trends in norm evolution of Twitter use, an evolution that has progressed quickly but appears to be stabilizing around specific textual conventions.

The Omni-Kernel Architecture: Scheduler Control Over All Resource Consumption in Multi-Core Computing Systems

Clouds commonly employ virtual machine technology to leverage and efficiently utilize computational resources in data centers. The workloads encapsulated by virtual machines contend for the resources of their hosting machines and interference from resource sharing can cause unpredictable performance. Despite the use of virtual machine technology, the role of the operating system as an arbiter of resource allocation persists—virtual machine monitor functionality is implemented as an extension to an operating system and the resources provided to a virtual machine are managed by an operating system. Visibility and opportunity for control over resource allocation is needed to prevent execution by one workload from usurping resources that are intended for another. If control is incomplete, no amount of over-provisioning can compensate for it and there will inevitably be ways to circumvent policy enforcement. The accurate and high fidelity control over resource allocation that is required from an operating system in a virtualized environment is a new operating system challenge. This dissertation presents the omni-kernel architecture, a novel operating system architecture designed around the basic premise of pervasive monitoring and scheduling. The architecture ensures that all resource consumption is measured, that the resource consumption resulting from a scheduling decision is attributable to an activity, and that scheduling decisions are finegrained. The viability of the omni-kernel architecture is substantiated through a faithful implementation, Vortex, for multi-core x86-64 platforms. Vortex instantiates all architectural elements of the omni-kernel and provides a large range of commodity operating system functionality and abstractions. Using Vortex, we experimentally corroborate the efficacy of the omni-kernel architecture by showing accurate scheduler control over resource allocation in scenarios with competing workloads. Experiments involving Apache, MySQL, and Hadoop quantify the cost of the omni-kernel pervasive monitoring and scheduling to be around 5% of CPU utilization or substantially less.
A Case Study on Assembly Block Operations Management at Shipyard

How to efficiently manage assembly blocks at shipyard has been a hot management issue in the shipbuilding Industry, because it has significantly influenced on the productivity of shipbuilding process. This paper introduces the real practice of assembly block operations management in Hyundai Heavy Industries (HHI) and the Ship Assembly Block Operations Optimization (SABOO) project that h3s been launched in HHI as an academy-and-industry collaborative project, aimed to diagnose problems, propose possible solutions, and develop a prototype system in order to search ways of improving the assembly block operations management. Through the field interviews, observations, and benchmarking studies, the SABOO project diagnosed the most rudimental and urgent problem and proposed possible solutions. In addition, the SABOO project developed the prototype system that embodied the visual function of monitoring the shipyard on a real-time and the Interactive block assignment function that utilized the assembly block assignment algorithm developed by the project. As a whole, the SABOO project tested the possibility and gained an insight in extending the functions of block transportation/stockyard management system.

Factors Influencing Chiropractors Who Choose not to Join Professional Associations

Background Professional associations are perceived to promote their professions and support their members. They can provide assistance with complaints, negotiate favourable professional indemnity insurance rates, provide access to research libraries and databases, and organise continuing professional development events. Despite these apparent advantages, about 1 in 3 Australian chiropractors choose not to belong to either of the two professional associations. Our study had three objectives: 1) to explore the views of non-member chiropractors about professional associations in general; and 2) seek to understand the motivations of non-member Australian chiropractors about not joining a professional association; and 3) to discover their reasons that might lead them to join a professional association. Methods This was a qualitative descriptive study utilising in-depth semi-structured interviews with open-ended questions for thematic analysis conducted from January to March 2020. It was estimated that between 6 -15 participants in total would be required to achieve saturation of data, that is, the point where no new themes were being articulated. Participants had to be registered chiropractors who had not been members of a professional association (PA) for the last five years. Recruitment was through a Facebook ad and snowball sampling. Interviews were transcribed and imported into NVivo qualitative analysis software, allowing identification of key concepts surrounding non-membership of chiropractic professional associations. Results Five themes were identified from the data. They were: “Not worth the money”, “Tarnished image of the profession”, “Going it alone / what’s in it for me”, “Lack of visibility”, and “Two warring factions”. The most commonly voiced suggestions for improvement included providing continuing professional development/lectures, frequent email updates about events affecting practice/business, improve the image of the profession through the media, and act as a regulator to the profession. Conclusions Non-members are looking for PAs to enhance the respectability of the profession in a manner that ultimately results in increased patient volume and the provision of readily accessible day-to-day resources and information. These results can inform the construction of a survey for the broader chiropractic non-membership community to confirm and expand upon these findings and improve PAs.
Solar System Wave Function and its Achievements

5 Pluto, Ceres and all planets of solar system except Neptune, with a high approximation, follow a 6 rule called Titius-Bode rule or Bode rule, which can by no means be considered as a stochastic 7 event. This rule shows that the distance of the planets from the sun in Solar system is regulated. 8 Here, we prove that the existence of a standing and cosine wave packet in solar system, with the 9 wavelength λ = 0.6 𝐴𝑈 ( 𝐴𝑈 represents the distance of earth from the sun) and the phase constant 10 ∅ 0 = 𝜋 6 , is the reason for Bode rule. Moreover, we prove that this huge wave packet belongs to 11 the sun. In the following of the article, based on the solar system wave function, we will enter into 12 the atomic field and arrive to a new atomic model that helps us to describe many phenomena such 13 as the normal Zeeman effect. 14

Non-rigid image registration of 4D-MRI data for improved target delineation of moving tumors in radiotherapy

Background: To increase the image quality of end-expiratory and end-inspiratory phases of retrospective respiratory self-gated 4D MRI data sets using non-rigid image registration for improved target delineation of moving tumors. Methods: End-expiratory and end-inspiratory phases of volunteer and patient 4D MRI data sets are used as targets for non-rigid image registration of all other phases using two different registration schemes: In the first, all phases are registered directly (dir-Reg) while next neighbors are successively registered until the target is reached in the second (nn-Reg). Resulting data sets are quantitatively compared using diaphragm and tumor sharpness and the coefficient of variation of regions of interest in the lung, liver, and heart. Qualitative assessment of the patient data regarding noise level, tumor delineation, and overall image quality was performed by blinded reading based on a 4 point Likert scale. Results: The median coefficient of variation was lower for both registration schemes compared to the target. Median dir-Reg coefficient of variation of all ROIs was 5.6 % lower for expiration and 7.0 % lower for inspiration compared with nn-Reg. Statistical significant differences between the two schemes were found in all comparisons. Median sharpness in inspiration is lower compared to expiration sharpness in all cases. Registered data sets were rated better compared to the targets in all categories. Over all categories, mean expiration scores were 2.92 ± 0.18 for the target, 3.19 ± 0.22 for nn-Reg and 3.56 ± 0.14 for dir-Reg and mean inspiration scores 2.25 ± 0.12 for the target, 2.72 ± 215 0.04 for nn-Reg and 3.78 ± 0.04 for dir-Reg. Conclusions: In this work, end-expiratory and inspiratory phases of a 4D MRI data sets are used as targets for non-rigid image registration of all other phases. It is qualitatively and quantitatively shown that image quality of the targets can be significantly enhanced leading to improved target delineation of moving tumors.
The Need for Change of the Transport Mode in the Great Cities of Romania

This paper describes how the development of the great cities in Romania, especially the capital of Bucharest, and the dramatic rise in the number of cars has contributed to the pollution of these cities and resulted in horrific urban traffic, particularly during the morning and evening rush hours. To provide alternative transportation in Bucharest and the surrounding areas, Urban Transport Administration of Bucharest (RATB) uses 300 km of tram lines with a park of 500 tram wagons, 18 trolley lines with a 485 km network and a park of 300 trolleys, the bus transport system with a 2,900 km network and a park of 1,300 buses, 3 Light Rail (LR) lines and 4 subway lines. During rush hour, the tram and trolley lines are obstructed by cars most of the time, so the average transport speed is 6–9 km/h for trolleys and 8–10 km/h for trams. The travel time for cars is around 220,000 vehicles/hour, 18,000 vehicles/hour for cabs, and 854,000 passengers/hour for urban transportation with electrical vehicles and buses. The impact on the environment can be measured in noise levels, which for 2007 were estimated at 62.8 dB and very high polluting car emissions. This paper will examine the decision factors and the planning concerns to provide a more efficient urban transport in Bucharest and other great cities in Romania, especially with electric vehicles. The paper proposes a methodology to optimize the selection mode and the track design for LR, using existing tram lines with the necessary additions, the construction of new subway lines for the busy areas and the continuous development of the tram and trolley urban transportation network.

Parallelism, anonymity, structure, and group size in electronic meetings

An Electronic Meeting System (EMS) is a computer-based environment that supports group meetings that may be dispersed in space and time. The focus of this dissertation is on EMS meeting rooms containing networked computer workstations that enable groups to meet face-to-face, with computer-supported electronic communication used to support or replace verbal communication. This electronic communication provides anonymity, the ability to work in parallel, and the ability to structure group interaction. This dissertation presents 10 laboratory and field studies using the University of Arizona GroupSystems EMS. The first experiment found 6- and 12-member EMS groups to be more satisfied and to generate more ideas of greater quality than similarly-sized verbally interacting groups. Experiments Two and Three found 9- and 12-member (respectively) EMS groups to be more satisfied and to generate more ideas than similarly-sized nominal groups (i.e., individuals working separately). Experiment Four found 18-member groups to generate more ideas than two 9-member groups, six 3-member groups or 18 individuals; and 12-member groups to generate more ideas than three 4-member groups or 12 individuals. The remaining three experiments examined the separate impacts of anonymity, parallelism, and structure. Parallelism and structure both had significant effects on performance; anonymity did not. The three field studies were conducted to help understand how organizational groups used this technology, and whether there was any evidence to support the theory developed and tested in the laboratory. The first studied 10 operations management groups, the second six small project teams, and the third organizations' use of EMS in the strategic management process. These field studies found EMS groups to perceive EMS support to improve effectiveness, efficiency, and satisfaction. These effects were stronger for larger groups and for groups that used more electronic communication relative to verbal communication. Parallelism, and to a lesser degree structure, where seen to be important. Anonymity was very important for groups with power and status differences, but had few effects for groups of peers or groups whose members worked together on a regular basis.
