And Performance

Safety, cost, ride quality, and performance are characteristics of pavement systems that are considered high-priority customer demands by transportation agencies throughout the world. Ride quality is the characteristic most notable to the traveling public. Throughout the United States, numerous state and federal agencies have developed specifications that require that road contractors meet a minimum level of ride quality before a pavement is approved for payment. Studies have shown that initial (as constructed) ride quality is an important factor in determining overall serviceability and length of time to rehabilitation or reconstruction. A case study in Cowley County, Kansas, in which the ride quality of an existing jointed, plain concrete pavement was significantly improved by the placement of a thin, polymer-modified, asphaltemulsion microsurfacing system, is described. The existing pavement conditions, the construction techniques used by the contractor, and the smoothness measurements before and after construction are noted and discussed. It was found that a marked reduction in roughness can be accomplished with unique construction techniques and microsurfacing.

Roughness Measurements

A case study of flexible overlay performance on an old rigid pavement is presented. This special study was devised in cooperation with the Pavement Section of the Design Division of the Texas Department of Transportation to take advantage of a unique opportunity to study overlay effectiveness. Condition survey, roughness measurements, and deflection basins were taken before and after the removal of an old flexible overlay and after the construction of a new asphalt overlay. Subsequent analysis of the data shows that although the overlay restores the ride quality of a rigid pavement and eliminates dynamic loading caused by swelling subgrades, it can only slow, not reverse, fatigue in the underlying pavement structure.

Abstract Background and Objectives U.S. Department of Veterans Affairs Medical Centers (VAMCs) contract with nursing homes (NHs) in their community to serve Veterans. This study compares the characteristics and performance of Veterans Affairs (VA)-paid and non-VA-paid NHs both nationally and within local VAMC markets. Research Design and Methods VA-paid NHs were identified, characterized, and linked to VAMC markets using data drawn from VA administrative files. NHs in the United States in December 2015 were eligible for the analysis, including. 1,307 VA-paid NHs and 14,253 non-VA-paid NHs with NH Compare measures in 128 VAMC markets with any VA-paid NHs. Measurements were derived from the Centers for Medicare and Medicaid Services (CMS) five-star rating system, NH Compare. Results VA-paid NHs had more beds, residents per day, and were more likely to be for-profit relative to non-VA-paid NHs. Nationally, the average CMS NH Compare star rating was slightly lower among VA-paid NHs than non-VA-paid NHs (3.05 vs. 3.21, p = .04). This difference was seen in all 3 domains: inspection (3.11 vs. 3.23, p < .001), quality (2.68 vs. 2.83, p < .001), and total nurse staffing (3.36 vs. 3.42, p < .10). There was wide variability across VAMC markets in the ratio of average star rating of VA-paid and non-VA-paid NHs (mean ratio = 0.93, interquartile range = 0.78–1.08). Discussion and Implications With increased community NH use expected following the implementation of the MISSION Act, comparison of the quality of purchased services to other available services becomes critical for ensuring quality, including for NH care. Methods presented in this article can be used to examine the quality of purchased care following the MISSION Act implementation. In particular, dashboards such as that for VA-paid NHs that compare to similar non-VA-paid NHs can provide useful information to quality improvement efforts.

The Impact

Abstract The main objective of the current study was to assess the impact of the water taken from the ‘Tunisian Refining Industries Company’ on meiobenthic nematodes, before and after a series of treatments in decantation basins followed by its discharge in Bizerte bay, Tunisia. The comparison of environmental parameters of the two types of water was clearly indicative of an improvement in the quality of treated waters after a significant reduction in their loads in hydrocarbons. Overall, the water retained a good quality after being treated by ‘Tunisian Refining Industries Company’ before discharge in the sea. At the end of the experiment, differential responses were observed according to the richness of sediment in organic matter and hydrocarbons. Thus, it was apparent that the nematode assemblage exposed to the treated waters was closer to controls and associated to higher values of abundance, than that under untreated ones. It was also assumed that the species Microlaimus honestus De Man, 1922, Paramonohystera proteus Wieser, 1956 and Cyartonema germanicum Juario, 1972 are sensitive bioindicators of bad environmental statues and of hydrocarbon presence in the environment. On the other hand, Metoncholaimus pristiurus (Zur Strassen, 1894) Filipjev, 1918 would rather be classified as a positive bioindicative species of this type of pollutants.

Quality Control Data

Quality management in the library is related to quality control of the library's work to meet user expectations and contributes to the continued success of the organization. However, quality control is lacking and not be the main focus in many libraries. This paper aims to explain how quality management improves work results in libraries. The research method used in this paper is qualitative research using a case study method. We conduct research in Library X that already underwent quality control in book processing activities. The data were collected through observation, and interviews for book processing activities and its quality control data during 2018-2020. The data was then analyzed document analysis. The study found that Library X could perform better by improving the quality of book processing and fixing the error just before they put the book on its shelves. Quality control gives a comprehensive evaluation in Library X either for humans, processes, and systems of book processing activities that help Library X conduct its duty to provide their user needs and expectations. Quality control and quality management also help Library X describe the library working atmosphere and can be used for giving motivation to all librarians and staff to give better service and performance for the end-users.

The aim of this article is to measure the effect on performance, of the innovation in the organizational structure of the laboratories for clinical research associated with healthcare in infectious diseases of the Evandro Chagas National Institute of Infectious Diseases (INI) at Fiocruz in 2007, na effect herein identified as representative of the corporate intangible assets resulting from such restructuring strategy. The method consists, first, in the analysis of the literature about the measurement of intangible assets and organizational innovation, the potential effects of organization�s structure in performance, and the assessment of multipurpose public organizations in health, as sources of the basic notion on relations between intangible assets, organizational structure and performance which is used in this research. Next, the empirical research involves: (a) characterizing the change in organizational structure of 8 INI laboratories; (b) quantifying variables on the use of consumer goods and specialized personnel and on the production of teaching, research and health care; (c) calculating indicators about the development of relative technical efficiency of INI laboratories in the period 2002-2014, through Data Envelopment Analysis (DEA); and (d) using these indicators to compare the performance of these laboratories before and after the organizational innovation associated with the adoption of the Innovative Structure in their restructuring. As a contribution to knowledge, opens up prospects of collaborative research in Administration, Accounting and Economics for the development of a metric for organizational innovation. As management contribution, confirms the association between restructuring of INI laboratories as Innovative Organizations and their improvement in performance. Although the case study method imposes limitations to the generalizability of these results, mainly because there are no sufficient multipurpose organizations that use this methodology in performance assessment, it brings evidence on the potential benefit of the entrepreneurial-oriented innovation for the expansion and improvement of multipurpose public organizations.

Racial Incidents

Racial and ethnic violence continues to be a major problem in the United States. Boston, which experienced hightened racial turmoil since its desegregation process, presents an excellent case study of a police department that faced the problem in a straightforward manner. Traditional methods of classifying and investigating racial incidents were viewed as ineffective. The Boston Police Department developed an innovative approach to the handling of racially motivated crime, which involved implementing a departmentwide policy and creating a specialized police unit. This unit was highly successful in uncovering incidents that under traditional reporting methods appeared commonplace. Upon further examination, these incidents, taken together, indicated persistent and compelling patterns of racial animus. The uncovering of these incidents, the subsequent relabeling of them into “community disorders,” and the development of innovative strategies are described. Policy implications and recommendations are presented. Critics may question the allocation of police resources to a problem that on the surface may appear minor. However, racial violence viewed in the aggregate form has dramatic impact on the quality of life for the victim. A police department that recognizes the significance of this problem is making an important statement about the kind of society we are and what we as a nation stand for.

Abstract China has a civil procedure for collective litigation, which is dubbed Chinese-style class action, as it differs from the U.S.-style class action in some important ways. Using securities class action as a case study, this Article empirically examines both the quantity and quality of reported cases in China. It shows that the number of cases is much lower than expected, but the percentage of recovery is significantly higher than that in the United States. Based on this, the Article casts doubt on the popular belief that China should adopt the U.S.-style class action, and sheds light on the much-debated issue concerning the relationship between public and private enforcement of securities law. The Article also discusses the future prospects of securities class action in China in light of some recent developments which may provide its functional equivalents, including the regulator-brokered compensation fund and public interest group litigation.

Biblical Values

Contextualisation is a process of seeking meaning and relevancy in a constantly changing world. It is a theological imperative if biblical values were to be relevant to everyone in the world. This research is a case study of InnerCHANGE South Africa (ICSA) efforts to be contextual. InnerCHANGE South Africa is part of an international missional order called InnerCHANGE, which was started in 1984 in the United States of America. International organisations face the danger of coming up with uniform principles and practices. Such uniformity is never innocent of cultural bias. It rendered their principles and practices relevant in some contexts and irrelevant in others. InnerCHANGE is an incarnational ministry that focuses on identification in communities of poverty. It described incarnational ministry as a model of Christ, a method, a message and a spiritual discipline. This study investigated how ICSA has been able to contextualise these four elements of incarnational ministry. It concluded that these contextualisation efforts are still work in progress. It pointed out the encouraging signs of seeing many local community members aligning themselves behind ICSA vision of seeing the gospel as the good news made visible. It finally pointed out the challenges of contextualisation it is still facing.Intradisciplinary and/or interdisciplinary implications: This article is based on the field of missiology. It engaged development studies, specifically grassroots community development, to point out one of the roles of the church in society, which is to participate in improving the quality of life of the vulnerable.
