Continuous models combining slacks-based measures of efficiency and super-efficiency
2022
AbstractIn the framework of data envelopment analysis (DEA), Tone (Eur J Oper Res 130(3):498–509, 2001) introduced the slacks-based measure (SBM) of efficiency, which is a nonradial model that incorporates all the slacks of the evaluated decision-making units (DMUs) into their efficiency scores, unlike classical radial efficiency models. Next, Tone (Eur J Oper Res 143(1):32–41, 2002) developed the SBM super-efficiency model in order to differentiate and rank efficient DMUs, whose SBM efficiency scores are always 1. However, as pointed out by Chen (Eur J Oper Res 226(2):258–267, 2013), some interpretation problems arise when the so-called super-efficiency projections are weakly efficient, le…
Nudge for justice : An ERP investigation of default effects on trade-offs between equity and efficiency
2020
Default options are an increasingly common tool used by organizations, managers, and policymakers to guide individuals’ behavior. We wondered whether the known preference for default options could constitute a nudge to achieve more equitable or more efficient results. Combining with event-related potentials, we found that both the default option and distributive justice contributed significantly to decision-making. The N200s and P300s were extracted using the tensor decomposition, which showed superiority in terms of capturing multi-domain features. The results demonstrated that greater brain activity associated with conflict monitoring was elicited in the trade-off between equity and effic…
Efektywność energetyczna budynków mieszkalnych, z uwzględnieniem akumulacji energii
2017
W społeczeństwie polskim wzrasta świadomość znaczenia efektywności energetycznej budynków mieszkalnych. W pracy dokonano analiza dostępnych rozwiązań z zakresu wykorzystania odnawialnych źródeł energii w budynkach mieszkalnych, a także możliwości magazynowania lokalnie wytworzonego ciepła oraz energii elektrycznej. Dokonano również charakterystyki efektywności zastosowania różnego typu źródeł energii odnawialnej w ramach mikrosieci energetycznych, wyposażonych w systemy magazynowania energii elektrycznej oraz cieplnej.
Evaluation of the efficiency of different harvesting methods of olives
2006
This paper reports the results of experimental tests carried out in Sicily about the harvesting of olives. Three varieties were selected (Biancolilla, Cerasuola and Nocellara del Belice); the tests were performed in three different periods with three different harvesting systems: manual, manual with pneumatic combs and mechanical harvesting. The aim of this study was to evaluate the work capacity and productivity of the three harvesting systems and the period maximising the mechanical harvesting efficiency. The damages caused to the trees after mechanical harvesting with a variable frequency shaker were also evaluated. Naturally fallen olives, Jean’s maturity index, detachment force, harves…
Undergraduate Students’ Acceptance of a Reciprocating One-File System for Endodontic Treatment
2020
Abstract Objectives Reciprocating endodontic one-file systems are a comparatively new method for root canal shaping. Even though the mechanical properties are comparable to modern rotating mechanical systems, data about subjective assessment and application quality are scarce. This study evaluates the reciprocating one-file system in undergraduate education. Materials and Methods A total of 42 undergraduate students without experience regarding reciprocating file systems filled in a questionnaire in four different points in time (t 1–t 4) anonymously. The questionnaire was based on a numerical rating scale ranging from 0 to 10. Statistical Analysis A least significant difference post-hoc an…
Increasing Sustainability of Growing Media Constituents and Stand-Alone Substrates in Soilless Culture Systems
2020
Peat-free growing media constituents and stand-alone substrates are the basis for the economic and ecological efficiency of the soilless culture system. Nevertheless, divergence between the model and practice still exists, coming from large gaps in the knowledge of alternative organic materials and of their effects on crop performance. A more detailed understanding of these topics is necessary to increase the soilless culture management capacity. In this respect, this critical review collects research outcomes concerning the sustainability of soilless culture and growing media constituents and their impact on the environment. In particular, the review covers designated articles stressing th…
Aspects Regarding Human Resources Management Streamlining within National and International Organizations
2014
Abstract The entire world is changing in order to achieve performance as an essential element designed to meet the needs and interests of individuals, organizations and society, as a whole. For that, it is necessary to efficiently know and use all the resources and possibilities possessed by the organization, among which human resources Management streamlining acquires new dimensions and special significances. Therefore, approaching certain theoretical aspects regarding the necessity and content of human resources Management streamlining within national and international organizations, as well as psychosocial valences in this field represent important social and objective matters, which are…
AN EMPIRICAL ANALYSIS OF THE PUBLIC SPENDING DECOMPOSITION ON ORGANIZED CRIME
2016
The aim of this paper is to investigate, empirically, what components of the public spending imply a decreasing effect on the organized crime and what components create opportunities for the organized crime, discussing also the role of government effciency. The findings show a strikingly consistent pattern. Organized crime mainly operates in the distribution of the public spending for health, housing and community amenities. There is a decreasing effect on organized crime of the public expenditure devoted to education and to create morality values, such as the expenditure for recreation, culture and religion. Finally, government efficiency in public spending is beneficial for reducing the o…
Introduction to the Symposium on Exploring the Complexities of Performance Management
2017
ABSTRACTThe editors of this symposium hope that this collection of articles can help advance the public administration literature stream across the multiple organizational and cultural settings in which these performance management studies were conducted. However, this symposium also focused on articles that can help advance the practice of performance management, where specific recommendations are needed to help public officials collect, analyze, and use meaningful outcome measures specifically for the benefits for making better management and policy decisions.
Economics of wage premia and wage rigidity
2017
The focus of this dissertation is on the effects of specific employer characteristics on wages and wage rigidity and how these characteristics enter the wage-setting process. The dissertation includes an introductory chapter and five separate essays. The introduction provides motivation, background on the main keywords and an overview of the thesis. Chapters two and three study how internal references affect wages and wage rigidity from a theoretical perspective. The fourth chapter estimates the effect of firm size on wages in the Finnish labor market. Chapter five develops on the preceding and analyses how profit sharing schemes affect the firm size premium. Chapter six studies how interna…
