In this paper we present a new solution for the highway interchange, which represents the best compromise between the traffic capacity, the land area used and construction cost. The difference between the known and the new design solution is in the implementation of the opposite directional ramps which are widely separated in the area of the interchange. In the middle, between the directional ramps, some space is created for the left directional ramps. Interchange should be used for four-way highway interchanges or other heavy traffic roads junction in order to increase the capacity and traffic safety at the crossing point. It has no conflict points. ITL Interchange left directional ramps is much shorter than all other known solutions for interchanges. The interchange is built in two levels. These two facts significantly lower the cost of construction. The study compares different types of interchanges. We made a geometric comparison and performance measures. In geometric comparison, the greatest advantages of the ITL interchange are the shortest overall roadway length and the shortest overpasses length. Therefore, such an interchange is advantageous in terms of construction and maintenance costs. When measuring performance, ITL Interchange achieves the best results regardless of the number of vehicles.

Optimal status and performance of the used parts can often make the difference between successful and unsuccessful remanufacturing for construction machinery. However, a used parts is remanufactured at an unreasonable time, there is a greater degree of resource waste and diseconomy. In this paper, a new method for determining the optimum active remanufacturing time is proposed, which considers both environmental and economic indicators. As an example, the life cycle assessment method was adopted for assessing the environmental impact of an oil cylinder over its entire service life, and an average annual cost model was established. Considering both the environmental index and the cost index, an optimization process was performed and the optimum active remanufacturing time for the oil cylinder was determined to be after 6.58 years of operation.

Like many Western European countries, Belgium and the Netherlands have been strongly hit by COVID-19. Almost simultaneously, the virus spread, caused a relatively high number of infections and severe lockdown measures were imposed; however, at the same time, the crisis management response has been sufficiently different to justify a systematic comparative analysis. We start with the premise that decisions made on the basis of incomplete information show the true nature of governments’ response to a crisis, which is conditioned by legacies arising from the past and organizational cultures, existing and new governance structures, and strategies used by specific actors. We show that the difference in crisis management echoes the countries’ different types of consociationalism, though also that Belgian federalism and Dutch decentralism impeded a truly coherent response. The cost of coordinating different government levels made a uniform approach difficult too. Actor strategies attempting to exploit the crisis seem to have influenced the response the least but did have an impact on perceptions of the response. Points for practitioners The article unravels how the governments in the Low Countries responded to the COVID-19 challenge in the first half of 2020. It allows practitioners to better understand that under circumstances of an imminent crisis, specific governance structures matter. It also reveals that the cost of coordination between the federated and the federal level turned out to be quite high in Belgium. In the Netherlands, a lot of autonomy was left to federated and local authorities. This too impeded a more coherent approach. COVID-19 certainly offers possibilities for policymakers to exploit the crisis but opportunities are not always taken.

PurposeIn an attempt to create national harmonisation of legislation, a set of model Work Health and Safety (WHS) Regulations were developed in Australia. These regulations require principal contractors to undertake specific WHS planning and coordination activities if the construction works to be completed cost AU $250,000 or more. However, there are some doubts about the usefulness of this monetary threshold. This study aimed to investigate how effective this threshold can be in Australia.Design/methodology/approachTo evaluate the performance and operation of this threshold in the Australian construction industry, this study modelled the costs of construction for four construction project scenarios – small classroom, two-storey home renovation with adjacent pool, small commercial warehouse and single-storey house (volume home builder) – under various conditions based on historical data (2011–2017) and in eight Australian jurisdictions.FindingsAmong the six study factors (i.e. the types for construction, geographical location, design specification, delivery method, contracting approach and inflation), the research found considerable variation in the operation and performance of the monetary threshold.Originality/valueThe research highlights some potential challenges associated with the use of a monetary threshold in the regulation of WHS planning in construction projects. Thus, the results are expected to contribute to addressing these challenges, leading to the development of an appropriate balance to achieve efficient and effective WHS regulation in Australia.

AbstractAfter 50 years of debate on this crucial question, the evidence is increasingly strong in favor of “yes”: companies can achieve better results if they incorporate practices that foster people’s sense of purpose. This relationship seems to be valid for very different types of industries and various business strategies within the cost-differentiation spectrum. However, causality between purpose and performance is not as linear as some literature and consultants seem to indicate. In this chapter, we discuss this relationship under the perspective of unity (the degree of mutual trust and commitment to the company experienced by people who contribute to fulfilling its purpose). Based on this perspective, we provide a framework that distinguishes four types of cultures: bureaucratic, paternalistic, aggressive and competent.

Abstract In recent years, the production of locomotives in our country has increased significantly. At the same time, a lot of efforts are made to increase the power, reliability and efficiency of their work. One of the key components of any locomotive is electric traction machines, which are usually designed to the limit in order to obtain maximum torque and power density in the limited space of the rolling stock. Previously, this problem was solved by increasing the electromagnetic properties of materials, thermal conductivity of insulating materials. However, this path has exhausted the possibilities for increasing the efficiency of traction electric machines. As the design of traction electric machines improves, their level of functionality, reliability and durability increases, electric traction systems become more relevant and important for reducing the cost of materials, maintenance and ensuring traffic safety. The insulation state of the windings of traction electric machines mainly determines their reliability and performance, affects the service life and the cost of maintenance. Therefore, when designing a traction electric machine, it is important to take into account all operational factors that determine the optimal service life of a locomotive. The article discusses the effect of thermomechanical stresses in the insulation of traction electric machines on their reliability and durability.

A type of geosynthetic material named geogrid plays a pivotal role in the behaviour of concrete by implementing them as an additional reinforcement. Geogrids have good tensile strength as they are formed by the reticulation of tensile elements with an opening of an ample size which allows interlock with the nearby fill materials. These grids are flexible mesh which is highly effective and enhances the life of the structure. The prime constituents of geogrid are polyester, high-density polyethylene, and polypropylene. More often, in the field of civil engineering,uni-axial, bi-axial and tri-axial geogrids are used. As the cost and duration of construction are nominal, geogrids can be optedfor cost-effective and resilient construction. They are frequently used as reinforcement and for stabilization in structures like retaining walls, pavements, foundations, slopes, and embankments. The geogrids are employed in various construction which results in sustainable development. Thus, this paper discusses diverse studies that have been carried out by using different types of geogrids for various purposes by different research scholars

The difference (D) between a person's Verbal IQ (VIQ) and Performance IQ (PIQ) has for some time been considered clinically meaningful ( Kaufman, 1976 , 1979 ; Matarazzo, 1990 , 1991 ; Matarazzo & Herman, 1985 ; Sattler, 1982 ; Wechsler, 1984 ). Particularly useful is information about the degree to which a difference (D) between scores is “abnormal” (i.e., deviant in a standardization group) as opposed to simply “reliable” (i.e., indicative of a true score difference) ( Mittenberg, Thompson, & Schwartz, 1991 ; Silverstein, 1981 ; Payne & Jones, 1957 ). Payne and Jones (1957) proposed a formula to identify “abnormal” differences, which has been used extensively in the literature, and which has generally yielded good approximations to empirically determined “abnormal” differences ( Silverstein, 1985 ; Matarazzo & Herman, 1985 ). However applications of this formula have not taken into account the dependence (demonstrated by Kaufman, 1976 , 1979 , and Matarazzo & Herman, 1985 ) of Ds on Full Scale IQs (FSIQs). This has led to overestimation of “abnormality” of Ds of high FSIQ children, and underestimation of “abnormality” of Ds of low FSIQ children. This article presents a formula for identification of abnormal WISC-R Ds, which overcomes these problems, by explicitly taking into account the dependence of Ds on FSIQs.

ABSTRACT This study compares key characteristics and performance of physicians referred to a clinical competence assessment and education program by state medical boards (boards) and hospitals. Physicians referred by boards (400) and by hospitals (102) completed a CPEP clinical competence assessment between July 2002 and June 2010. Key characteristics, self-reported specialty, and average performance rating for each group are reported and compared. Results show that, compared with hospital-referred physicians, board-referred physicians were more likely to be male (75.5% versus 88.3%), older (average age 54.1 versus 50.3 years), and less likely to be currently specialty board certified (80.4% versus 61.8%). On a scale of 1 (best) to 4 (worst), average performance was 2.62 for board referrals and 2.36 for hospital referrals. There were no significant differences between board and hospital referrals in the percentage of physicians who graduated from U.S. and Canadian medical schools. The most common specialties referred differed for boards and hospitals. Conclusion: Characteristics of physicians referred to a clinical competence program by boards and hospitals differ in important respects. The authors consider the potential reasons for these differences and whether boards and hospitals are dealing with different subsets of physicians with different types of performance problems. Further study is warranted.
