Abstract

Purpose

The purpose of this paper is to synthesize oil-soluble copper (Cu) nanoparticles modified with free phosphorus and sulfur modifier and investigate its tribological properties as environment-friendly lubricating oil additives.

Design/methodology/approach

To improve the anti-oxidation properties of these nanoparticles, two kinds of surface modifiers, oleic acid and oleylamine were used simultaneously. The morphology, composition, structure and thermal properties of as-synthesized Cu nanoparticles were investigated by means of transmission electron microscopy, X-ray powder diffraction, Fourier transform infrared spectrometry and differential thermal and thermogravimetric analysis. The tribological properties of as-synthesized Cu nanoparticles as an additive in liquid paraffin were evaluated with a four-ball friction and wear tester.

Findings

It has been found that an as-synthesized Cu nanoparticle has a size of 2-5 nm and can be well dispersed in organic solvents. Tribological properties evaluation results show that as-synthesized Cu nanoparticles possess excellent anti-wear properties as an additive in liquid paraffin. The reason lies in that as-synthesized surface-capped Cu nanoparticles are able to deposit on sliding steel surface and form a low-shearing-strength protective layer thereon, showing promising application as an environmentally acceptable lubricating oil additive, owing to its free phosphorus and sulfur elements characteristics.

Originality/value

Oil-soluble surface-modified Cu nanoparticles without phosphorus and sulfur were synthesized and its tribological properties as lubricating oil additives were also investigated in this paper. These results could be very helpful for application of Cu nanoparticles as environment-friendly lubricating oil additives.

Abstract

Much of the literature on citizen participation in the budget process links the council-manager form of government with higher levels of citizen participation, assuming the council-manager form represents professional administration. This is contradictory to the reality that different forms of government have “borrowed” features from each other and many now have mixed forms of government (i.e., adapted). The literature also contains ambiguities about city managers’ role in participatory budgeting. We review the literature and identify three competing theories about the role of professional managers in the budget process. We directly examine the effect of city managers in terms of their professional dimensions, institutional environment, and individual willingness to represent citizens. Using survey data from Florida, we demonstrate that managers’ professionalism, perceived political environment, and attitude toward citizen input are important factors explaining local governments’ adoption of participatory budgeting.

Abstract

Purpose

This paper aims to propose image stitching by reduction of full line and taking line image as registration image to solve the problem of automatic optic inspection in PCB detection. In addition, surf registration was introduced for image stitching to improve the accuracy and speed of stitching.

Design/methodology/approach

First, image stitching proceeded by method of full line reduction and taking line image as registration image; second, surf registration was introduced based on the traditional PCB image stitching algorithm. Scale space of the image pyramid was adopted for confirming relative future points between stitching image. The registration means of nearest neighbourhood and next neatest neighborhood was selected for feature matching and fused in region of interest to fulfil image stitching.

Findings

The improved stitching algorithm with small data size of image, high speed and noncumulative transitive error eliminated displacement deviation and solved the stitching gap caused by uneven illumination, to greatly improve the accuracy and speed of stitching.

Research limitations/implications

The research of this paper can only used for appearance detection and cannot be used for solder joint inspection with circuit detection or invisible solder joint detection; it can identify and mark PCB component defects but cannot classify automatically, thus artificial confirmation and processing is needed.

Originality/value

Based on the traditional image stitching means, this paper proposed full line reduction for image stitching, which reduces processing of data and speeds up image stitching; in addition, surf registration was introduced into the study of PCB stitching algorithm, which greatly improves the accuracy and speed of stitching and solves stitching gap formed by opposite variation trend of image local edge caused by uneven illumination.

Abstract

Purpose

The purpose of this paper is to examine March and Olsen’s 1983 study of American Government reorganization attempts between 1904 and 1980 in relation to three debates in management history scholarship. Can explorations of the past yield innovative interpretations of the present and future organizational activities? What is the role of multiple perspectives in understanding complex reality? How should management historians react to the differences in power held by various actors in historical scenarios and to the absence of documented evidence of the stances of many traditionally underrepresented groups?

Design/methodology/approach

The paper analyzes March and Olsen’s 1983 historical study on federal government reorganizations in relation to twentieth-century political science/public administration scholarship from 1919 to the present showing the unique focus and conclusion of March and Olsen’s work. The paper relates this focus and conclusions to three management questions.

Findings

This analysis shows that March and Olsen’s interpretation of American reorganization has had a significant impact on the work of political scientists studying programs that did not exist in 1983; this impact suggests how historical scholarship can invigorate understanding of current programs. The analysis also gives evidence to support March and Olsen’s focus on the importance of considering multiple perspectives to interpret complex realities. The analysis concludes that despite March’s acknowledging the importance of anti-establishment scholarship, March and Olsen’s 1983 work did not explore the role of power differentials or the voices of the oppressed in government reorganizations.

Originality/value

The value of this paper is that it seeks to relate March and Olsen’s work to a scholarship domain where it has not often been considered. Management historians lament that their work and concerns have often been considered peripheral by the greater management field. By showing how a major management theorist such as March used historical analysis to further understanding of contemporary organizations the paper heightens the visibility and importance of management history work.

Abstract

Purpose

The purpose of this paper is to add information on which voices contributed to the scientific management narrative from Frederick Taylor’s 1915 death to the early 1930s with a focus on the role of labor union representatives. The strategy is to analyze the role of labor representatives as participants in Taylor Society meetings and publications. The research contributes to the management history literature by bolstering the picture of the Taylor Society as a liberal, pro-labor organization. The research also shows that the Taylor Society was an early proponent of the idea that assembling diverse groups for dialogue improves organizational problem-solving.

Design/methodology/approach

The research analyzes historical sources including all issues of the Society’s bulletin from 1914 to 1933 and unpublished material from the Morris Cooke papers and the papers in the Frederick Taylor archive at Stevens Institute of Technology.

Findings

Taylor Society leaders took a proactive view of encouraging labor voices to join managers and academics in society meetings. At the beginning, few labor leaders spoke at the society, and often, at least some of their comments were critical of scientific management. By 1925, labor participation increased with William Green, American Federation of Labor (AFL) president appearing several times. In addition, labor leaders became positively inclined toward having scientific management experts working in industrial settings. The labor leaders who participated at Taylor Society meetings in the late 1920s and early 1930s considered scientific management insights as useful for labor and wanted to cooperate with the researchers.

Originality/value

The paper augments a revisionist view of interwar scientific management as progressive and pro-labor, a contested point in the management history literature. The research also shows how the Taylor Society was an early proponent of the importance of diversity, at least in the areas of gender and socioeconomic status, for effective problem-solving.

Abstract

Purpose – The chapter aims to analyse specific management tools which can be used to facilitate public governance practices, such as the process of stakeholder involvement.Methodology/approach – By means of both a theoretical discussion and an empirical research conducted on Italian local public utilities (LPUs), the chapter attempts to understand: (a) the degree of application of quality management, sustainability mechanisms and stakeholder's involvement; (b) the correlation between the application of these tools stakeholder involvement processes.Findings – Not all the tools imported from the private sector have the same ‘attitudes’ for stakeholder involvement evidencing a gap of Italian LPUs in quality management systems in ensuring that stakeholders and their contribution to product value is considered. These results give support to the necessity to move beyond New Public Management. Therefore, governance becomes a new process for developing and implementing public policies: this requires original mechanisms of coordination among institutional actors, public authorities and stakeholders.Research limitations/implications – This study gives rise to new research path in LPUs corporate governance research. Looking for the creation of a series of suppositions and considerations as to why LPUs actively venture into the practice of good corporate governance trough stakeholder involvement. Accordingly, it is necessary to invest in the debate on the tasks of the board of directors.Originality/value of paper – This study gives a new path of research, asking board of directors to move toward a stakeholder-conscious governance model, with broader input and ongoing engagement, as an important aspect for a better corporate governance in public administrations.

Abstract

The purpose of this exploratory research is to identify key motivations, administrative costs, and instrumental benefits of translating data-rich budgets into user-friendly reports for citizens. This research draws from interviews with chief financial officers in local governments that are recognized by the Government Finance Officers Association for preparing additional financial reports that appeal to a citizen-based audience. Candid discussions and thoughtful reflections of respondents demonstrate that chief financial officers play a leading role in determining the style and extent to which financial information is communicated to external audiences. The research suggests that adopting this form of financial reporting, however, does not necessarily have an impact on citizen participation in the budget process. Recommendations from the point of view of the research participant are presented for practitioners interested in implementing citizen-based financial reporting. The research concludes with a discussion of the state of practice of citizen-based financial reporting of the research sample and areas for future study.

Abstract

The environment in which public administrators are working is increasingly becoming one that is based on network relationships and expectations for active collaboration. Within this evolving environment the value preferences of administrators are subject to challenge and possible change. This article offers an approach to understand the dynamics of value preferences of public administrators through the lenses of stakeholder theory and bureaucratic responsiveness. A set of propositions are offered for future empirical study and to begin a discussion on the relationship between responsiveness, value creation, and the ultimate achievement of successful collaboration

Abstract

Purpose

The ecological environment of the Loess Plateau, China, is extremely fragile under the context of global warming. Over the past two decades, the vegetation of the Loess Plateau has undergone great changes. This paper aims to clarify the response mechanisms of vegetation to climate change, to provide support for the restoration and environmental treatment of vegetation on the Loess Plateau.

Design/methodology/approach

The Savitsky–Golay (S-G) filtering algorithm was used to reconstruct time series of moderate resolution imaging spectroradiometer (MODIS) 13A2 data. Combined with trend analysis and partial correlation analysis, the influence of climate change on the phenology and enhanced vegetation index (EVI) during the growing season was described.

Findings

The S-G filtering algorithm is suitable for EVI reconstruction of the Loess Plateau. The date of start of growing season was found to gradually later along the Southeast–Northwest direction, whereas the date of the end of the growing season showed the opposite pattern and the length of the growing season gradually shortened. Vegetation EVI values decreased gradually from Southeast to Northwest. Vegetation changed significantly and showed clear differentiation according to different topographic factors. Vegetation correlated positively with precipitation from April to July and with temperature from August to November.

Originality/value

This study provides technical support for ecological environmental assessment, restoration of regional vegetation coverage and environmental governance of the Loess Plateau over the past two decades. It also provides theoretical support for the prediction model of vegetation phenology changes based on remote sensing data.
