Open access self-archiving: An author study
No full textThis, our second author international, cross-disciplinary study on open access had 1296 respondents. Its focus was on self-archiving. Almost half (49%) of the respondent population have self-archived at least one article during the last three years. Use of institutional repositories for this purpose has doubled and usage has increased by almost 60% for subject-based repositories. Self-archiving activity is greatest amongst those who publish the largest number of papers. There is still a substantial proportion of authors unaware of the possibility of providing open access to their work by self-archiving. Of the authors who have not yet self-archived any articles, 71% remain unaware of the option. With 49% of the author population having self-archived in some way, this means that 36% of the total author population (71% of the remaining 51%), has not yet been appraised of this way of providing open access. Authors have frequently expressed reluctance to self-archive because of the perceived time required and possible technical difficulties in carrying out this activity, yet findings here show that only 20% of authors found some degree of difficulty with the first act of depositing an article in a repository, and that this dropped to 9% for subsequent deposits. Another author worry is about infringing agreed copyright agreements with publishers, yet only 10% of authors currently know of the SHERPA/RoMEO list of publisher permissions policies with respect to self-archiving, where clear guidance as to what a publisher permits is provided. Where it is not known if permission is required, however, authors are not seeking it and are self-archiving without it. Communicating their results to peers remains the primary reason for scholars publishing their work; in other words,
researchers publish to have an impact on their field. The vast majority of authors (81%) would willingly comply with a mandate from their employer or research funder to deposit copies of their articles in an institutional or subject-based repository. A further 13% would comply reluctantly; 5% would not comply with such a mandate
Virtual vs. Standard Strike: An Experiment
No full textIn this paper we compare - in the laboratory - stoppage and virtual strike. Our experiment confirms that higher wages offered by an employer lead to considerably more costly effort provision. The number of strikes, the level of efforts and average total payoffs are higher under virtual strike than under standard strike. However, when standard strike is associated with reciprocal externalities, it induces higher effort levels, higher payoffs and an extremely reduced number of strikes than virtual strike. It is unclear whether this behavior re?ects reciprocity or other forms of social preferences. However our results might explain why standard strikes rather than virtual ones are generally adopted by workers.virtual strike, cooperation, reciprocity, fairness, experiments
Efficiency wages, public service motivation and effort in Malaysia: An empirical case study of Universiti Sains Malaysia
No full textUntil now, the bulk of the studies conducted on the relationships between efficiency wages, public service motivation (PSM), and effort focused exclusively on developed and advanced countries. Very little has been written about these relationships on developing countries. Finding additional knowledge on the experiences of the developing countries would not only be helpful in improving the efficiency of public employees in developing countries, but would also help to enrich and expand this field of knowledge. Perhaps of more importance is that this study were provides some rare glimpses into the dynamics of the relationship between public sector employers and employees in achieving their prescribed outcomes from a developing world perspective. Malaysia is taken as a case study to explore and highlight some common problems shared by many developing countries in improving the efficiency of their public employees. As far as the author could judge (after an extensive review of the literature), this is the first attempt to analyse the relationships between efficiency wages, PSM, and effort on Malaysia.
The relationships between efficiency wage, PSM, and effort were analysed and tested on the Malaysian public sector using Universiti Sains Malaysia (USM) as a case study. This study found employees’ effort levels in USM during the survey period were driven more so by PSM rather than by efficiency wages. This study also highlighted a few policy recommendations based on findings of this study
The vanishing author in computer-generated works: a critical analysis of recent Australian case law
No full textAbstract
The use of software is ubiquitous in the creation of many copyright works, yet the requirement in copyright law that every work have a human author who engages in independent intellectual effort means that its use may prevent copyright subsistence. Several recent Australian cases have refocused attention on authorship as an essential criterion of copyright subsistence, and these cases suggest that much computer-produced output may be authorless and thus lack copyright protection. This article, the first in a two-part series, analyses how each case deals with the question of authorship of computer-produced works and why the use of software diminishes copyright protection for a significant number of computer-generated works. The article critiques the application of conventional notions of human authorship developed in the pre-computer age to modern productions and suggests alternative approaches to authorship that satisfy both the major objectives of copyright policy and the need to adapt to the computer age. The article argues that, without a broader judicial approach to authorship of computer-generated works, Parliament must remedy the lacuna in protection for these ‘authorless’ works. Possible solutions for reform are suggested. In a forthcoming article, the author comprehensively examines those reform proposals
Diffused effort, asset heterogeneity, and real estate brokerage
No full textWe generalize the classic Williams (1998, Review of Financial Studies, 11, 239–280) brokerage model by introducing diffused effort and asset heterogeneity. The term "diffused effort" refers to the fact that an agent can cross‐utilize effort spending on one listing to another. One counterintuitive finding in Williams' paper is the absence of the agency problem. As a special case in our model, we recover the agency problem. We demonstrate the positive externality due to the diffused effort and show it depends on the agent's inventory size. Hence, there is a trade‐off between agents' effort committed to existing listings and expanding network size by soliciting new listings.Peer reviewedFinal article published.DC Author's celebration 202
Congestion control mechanisms and the best effort service model
No full textIn the last few years there has been considerable research toward extending the Internet architecture to provide quality of service guarantees for the emerging real-time multimedia applications. QoS provision is a rather controversial endeavour. At one end of the spectrum there were proposals for reservations and per-flow state in the routers. These models did not flourish due to the network's heterogeneity the complexity of the mechanisms involved, and scalability problems. At the other end, proposals advocating that an overprovisioned best effort network will solve all the problems are not quite convincing either. The authors believe that more control is clearly needed for protecting best effort service. An important requirement is to prevent congestion collapse, keep congestion levels low, and guarantee fairness. Appropriate control structures in a best effort service network could even be used for introducing differentiation. This could be achieved without sacrificing the best effort nature of the Internet or stressing its architecture beyond its limits and original design principles. We revisit the best effort service model and the problem of congestion while focusing on the importance of cooperative resource sharing to the Internet's success, and review the congestion control principles and mechanisms which facilitate Internet resource sharin
Leaf damage and prey type determine search effort in Orius tristicolor
No full textComponents of search effort were determined for adult females of Orius tristicolor (White) (Hemiptera: Anthocoridae) on bean, Phaseolus vulgaris L., leaves with either western flower thrips, Frankliniella occidentalis (Pergande) (Thysanoptera: Thripidae) or twospotted spider mites, Tetranychus urticae (Koch) (Acari: Tetranychidae) as prey. In the absence of prey, females of O. tristicolor allocated significantly more search time to leaves damaged by western flower thrips than to leaves damaged by twospotted spider mites, artificially damaged leaves or undamaged leaves. In the presence of prey, search time increased with increasing amounts of leaf damage for both prey species, but was not affected by prey species. Amounts of leaf damage or type of prey did not affect giving‐up‐time. The proportion of predators that successfully located thrips increased with increasing amounts of thrips damage on leaves. Females of O. tristicolor appeared to follow some simple, behavioural rules‐of‐thumb for allocation of search effort. The presence and type of damage determined the initial effort allocated to searching a leaf. Subsequent effort was determined by successful capture of prey, regardless of species. The implications of these results for application of Orius spp. for biological control are discussed.

Revisiting the debate: Are code metrics useful for measuring maintenance effort?
No full textEvaluating and predicting software maintenance effort using source code metrics is one of the holy grails of software engineering. Unfortunately, previous research has provided contradictory evidence in this regard. The debate is still open: as a community we are not certain about the relationship between code metrics and maintenance impact. In this study we investigate whether source code metrics can indeed establish maintenance effort at the previously unexplored method level granularity. We consider ∼ 730K Java methods originating from 47 popular open source projects. After considering seven popular method level code metrics and using change proneness as a maintenance effort indicator, we demonstrate why past studies contradict one another while examining the same data. We also show that evaluation context is king. Therefore, future research should step away from trying to devise generic maintenance models and should develop models that account for the maintenance indicator being used and the size of the methods being analyzed. Ultimately, we show that future source code metrics can be applied reliably and that these metrics can provide insight into maintenance effort when they are applied in a judiciously context-sensitive manner.Green Open Access added to TU Delft Institutional Repository 'You share, we take care!' - Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Software Engineerin
Effects of tax reform on Argentina's revenues
No full textToo often, a good tax policy proposal is considered sufficient to improve the tax system - too little consideration is given to weaknesses in tax administration, perhaps because of measurement problems. Analyzing legal and administrative measures and quantitatively evaluating their impact on tax revenues is generally arduous. The authors develop a simple approach to assessing how tax effort affects tax revenues (performance). By"tax effort"they mean changes in tax legislation (except changes in nominal taxes), tax administration, and individual taxpayers attitudes toward tax evasion. Changes in tax administration include increasing tax penalties, new technologies, and administrative reform. They measure tax effort as a residual: the variations in tax revenues that cannot be explained by changes in economic variables and tax structures. Using this approach, one can easily identify factors that influence tax revenues over time, and understand the behavior of tax revenues in developing countries, particularly where macroeconomic conditions are volatile. The authors apply this approach to Argentina; it can easily be applied to other countries. Their main conclusions in this application follow. The administrative dimension of tax reform is at the heart of Argentina's recent fiscal adjustment. Since 1991, tax effort is an average 80 percent higher than during the preceding (temporary) successful adjustment period (under the Austral Plan). An efficient tax administration and an improvement in taxpayer compliance levels appear to precede rather than follow increases in tax revenues. Tax effort is influenced significantly by such macrovariables as GDP growth and inflation, as well as by political (in)stability. It is influenced less by such fiscal variables as alternative sources of financing. In Argentina, the sequence of the tax effort was, first, to broaden the potential value added tax base, and then to reduce tax evasion through higher tax penalties and improvements in the basic functions of tax administration (inspection, audits, tax management, and personnel policy).Public Sector Economics&Finance,Tax Policy and Administration,National Governance,Taxation&Subsidies,Environmental Economics&Policies
Cognitive processing of miscommunication in interactive listening: An evaluation of listener indecision and cognitive effort
No full textPurpose: The purpose of the current study was to evaluate the social and cognitive underpinnings of miscommunication during an interactive listening task. Method: An eye and computer mouse-tracking visualworld paradigm was used to investigate how a listener’s cognitive effort (local and global) and decision-making processes were affected by a speaker’s use of ambiguity that led to a miscommunication. Results: Experiments 1 and 2 found that an environmental cue that made a miscommunication more or less salient impacted listener language processing effort (eye-tracking). Experiment 2 also indicated that listeners may develop different processing heuristics dependent upon the speaker’s use of ambiguity that led to a miscommunication, exerting a significant impact on cognition and decision making. We also found that perspective-taking effort and decision-making complexity metrics (computer mouse tracking) predict language processing effort, indicating that instances of miscommunication produced cognitive consequences of indecision, thinking, and cognitive pull. Conclusion: Together, these results indicate that listeners behave both reciprocally and adaptively when miscommunications occur, but the way they respond is largely dependent upon the type of ambiguity and how often it is produced by the speaker.Green Open Access added to TU Delft Institutional Repository 'You share, we take care!' - Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Human-Robot Interactio
