The single publication H-index of papers in the Hirsch-core of a researcher and the indirect H-index

The single publication H-index of Schubert is applied to the papers in the Hirsch-core of a researcher, journal or topic. Four practical examples are given and regularities are explained: the regression line of the single publication H-index of the ranked papers in the Hirsch-core is decreasing. We propose two measures of indirect citation impact: the average of the single publication H-indices of the papers in the Hirsch-core and the H-index of these single publication H-indices, defined as the indirect H-index. Formulae for these indirect citation impact measures are given in the Lotkaian context.     

The Patient Care Notebook: quality improvement on a rehabilitation unit

BACKGROUND: Shortened lengths of stay in acute and rehabilitation hospitals, continuing financial pressures on all postacute care services, and increasing out-of-pocket health care costs for patients and families challenge rehabilitation hospitals' patient education and discharge planning processes. Spaulding Rehabilitation Hospital (Boston) introduced a patient care notebook in a 15-bed satellite unit and pilot tested its contribution to the patient education and discharge planning process. DEVELOPING THE NOTEBOOK: The three-ring binder notebook included sections on medical appointments and phone numbers, understanding illness and medical care, coping with illness, physical activities, recommendations for the home, and community resources, with both standard and patient-specific information. RESULTS: Most of the patients and caregivers who received the notebooks found them to be helpful, and most staff indicated that the notebook improved the teaching process. Telephone calls to the unit after home discharges decreased form 28 calls for 11 discharges to 6 calls for 21 discharges after the notebook began to be used regularly. DISCUSSION: Staff felt that the process of using the notebook helped focus attention on teaching during the entire course of a patient's hospitalization rather than just a day or two before discharge. The patient care notebook process is being introduced to the entire hospital and to all patients, regardless of discharge location and the patient's literacy or proficiency with English. CONCLUSION: In using the notebook, the QI team, and the entire unit staff, learned about the complexities of QI, patient education, and discharge planning. The notebook process was implemented throughout the hospital a little more than a year after the completion of the pilot project.     

Product quality improvement method in manufacturing process based on kernel optimisation algorithm

Quality data in manufacture process has the features of mixed type, uneven distribution, dimension curse and data coupling. To apply the massive manufacturing quality data effectively to the quality analysis of the manufacture enterprise, the data pre-processing algorithm based on equivalence relation is employed to select the characteristic of hybrid data and preprocess data. KML-SVM (Optimised kernel-based hybrid manifold learning and support vector machines algorithm) is proposed. KML is adopted to solve the problems of manufacturing process quality data dimension curse. SVM is adopted to classify and predict low-dimensional embedded data, as well as to optimise support vector machine kernel function so that the classification accuracy can be maximised. The actual manufacturing process data of AVIC Shenyang Liming Aero-Engine Group Corporation Ltd is demonstrated to simulate and verify the proposed algorithm.

The AMA clinical quality improvement forum on addressing patient safety

BACKGROUND: More than 200 health care policy makers and researchers, clinicians, quality professionals, and other representatives of health care organizations, government, and academia attended the Division of American Medical Association Clinical Quality Improvement's conference, "Addressing Patient Safety," April 28, 2000, in Chicago--the first national conference to respond to the recent Institute of Medicine (IOM) report, To Err Is Human: Building a Safer Health System. ADDRESSING PATIENT SAFETY--PUBLIC AND PRIVATE PERSPECTIVES: John M. Eisenberg, MD, stated that research on errors is needed to describe the scope and nature of the problem, understand the barriers to and benefits of improvement, and develop and test strategies for improvement. Kenneth W. Kizer, MD, MPH, stated that the National Quality Forum will develop a compendium of best practices and will develop core measures for serious adverse events, and health care organizations and government health programs should act now to make a clear organizational commitment to patient safety, create a nonpunitive health care culture of safety, and implement known safe medication practices. Alan R. Nelson, MD, stated that the IOM report places its emphasis on continuous quality improvement and technology that can be used to mitigate the risks in a complex health system. HOSPITAL AND ACCREDITATION AGENCY ACTIVITIES ON PATIENT SAFETY ISSUES: Donald M. Nielsen, MD, discussed the American Hospital Association's (AHA's) Medication Safety Initiative, which promised to provide its members with successful practices, tools, and resources and to track progress of implementation of the recommended successful practices. Dennis S. O'Leary, MD, stated that when a hospital reports a sentinel event, the hospital is expected to implement improvements to reduce risk and monitor their effectiveness. The National Committee for Quality Assurance is considering changes to its accreditation standards to further address patient safety.     

Enhancement in quality and productivity: a riskless approach based on optimum selection of tolerance and improvement strategies

The need of higher quality products from the customers and the tendency of industries to quality improvement for maintaining their competitive position over the long run are the main motives of using improvement methodologies. However, any use of improvement methodology besides its additional costs will also change the total variability of the process. Changes in total variability will affect the optimal value of tolerance as well as the quality of the product. Therefore, one of the main concerns of the producers is to find an effective way to manufacture their goods in a manner that reduces the production costs and gains customers’ satisfaction. To meet these goals, this study introduces an algorithm to propose a riskless approach of improvement that results in the maximum amount of net savings. It is shown that using appropriate improvement strategies simultaneous with a proper selection of tolerance have an important impact to enhance productivity and quality.     

H-Classics: characterizing the concept of citation classics through H-index

Citation classics identify those highly cited papers which are an important reference point in a research field. To identify a paper as a citation classic we have to fix a citation threshold value. Usually, this threshold value should not be the same for all research fields because each field presents its respective citation pattern. Studies of citation classics in the literature define particular criteria and methods to set citation thresholds, which are often set arbitrarily and designed ad-hoc, and do not allow the scientific community to validate and compare their results. In this paper we introduce the concept of H-Classics to overcome this problem and provide scientific community a standardization of key constructs. We present a new and systematic method to identify citation classics. This identification method of highly cited papers is based on the H-index and thank to the properties of H-index it is sensitive to the own characteristics of any research discipline and also its evolution. Therefore, the concept of H-Classics allows to systematize search procedure of citation classics for any field of research.

Fairly sharing the credit of multi-authored papers and its application in the modification of <Emphasis Type=Italic>h</Emphasis>-index and <Emphasis Type=Italic>g</Emphasis>-index

Except the alphabetic ordering authorship papers, the citations of multi-authored papers are allocated to the authors based on their contributions to the paper. For papers without clarification of contribution proportion, a function of author number and rank is presented to rightly determine the credit allocated proportion and allocated citations of each author. Our citation allocation scheme is between the equally fractional counting and the one using the inverse of author rank. It has a parameter to adjust the credit distribution among the different authors. The allocated citations can either be used alone to indicate one’s performance in a paper, or can be applied in the modification of h-index and g-index to represent the achievement of a scientist on the whole. The modified h-index and g-index of an author makes use of more papers in which he or she played important roles. Our method is suitable for the papers with wide range of author numbers.     

The quality of single and multiple authored papers; An unresolved problem

Evidence is examined for the repeated claim that published papers with more than one author are, on average, of higher quality than those with a single author. Among published studies it is shown that no clear conclusion can be drawn, though evidence supporting the claim is stronger in astronomy and physics than among the social sciences. An empirical study of 656 papers in four Australian science journals produced negative results. Possible reasons for the differing results, and difficulties in researching the field, are highlighted.     

The motivation for citing specific references by social scientists in Korea: The phenomenon of co-existing references

This study, based on the premise that references are a social product that reflects the social environment of a society, is an attempt to explore the co-existence of Korean and non-Korean literature in the references to Korean papers. 321 authors (papers) who published in 43 issues of 24 Korean journals focused on the social sciences were surveyed about their research channels and citation motivations, and the 11,358 references in the papers were analyzed. The findings were as follows : (1) The extent of the co-existence was that non-Korean literature was cited 1.9 times (65.3%) more often than Korean literature; (2) Research channel was the most common non-Korean channel orientation (55.8%); (3) The motivation for citations was significantly dependent on whether the literature cited was Korean or non-Korean. Non-Korean literature was chiefly cited for conceptual (20.7%), perfunctory (16.0%), and persuasive (15.1%) motivations; (4) The citations and citation motivations behind non-Korean literature were significantly influenced by research channel, discipline, focus of research, publishing career, and type of paper. Of these variables, research channel was frequently related to the citation of non-Korean literature. Finally, this study is very suggestive on two counts: (1) Citation motivation might constitute a new approach for exploring the production of knowledge by researchers. (2) This study has demonstrated, in particular, an empirical relationship between knowledge produced by Korean social scientists and non-Korean knowledge through the analysis of citation motivation.

The simultaneous scaling of cited and citing articles in a common space

Scientific articles may be represented as points in a space whose spatial pattern reflects some of the substantive and social structures of science. The proximity of articles and the documents they reference leads to a centroid scalling method proposed in this paper. This method scales citing articles as close as possible to the articles they reference. The simultaneous scaling of citing and cited articles in a common space aids in the interpretation of the resultant configuration.     

Predicting scientific impact based on <Emphasis Type="Italic">h</Emphasis>-index

Predicting the future impact of a scientist/researcher is a critical task. The objective of this work is to evaluate different h-index prediction models for the field of Computer Science. Different combinations of parameters have been identified to build the model and applied on a large data set taken from Arnetminer comprised of almost 1.8 million authors and 2.1 million publications’ record of Computer Science. Machine learning prediction technique, regression, is used to find the best set of parameters suitable for h-index prediction for the scientists from all career ages, without enforcing any constraint on their current h-index values with R ² as a metric to measure the accuracy. Further, these parameters are evaluated for different career ages and different thresholds for h-index values. Prediction results for 1 year are really good, having R ² 0.93 but for 5 years R ² declines to 0.82 on average. Hence inferred that prediction of h-index is difficult for longer periods. Predictions for the researchers having 1 year experience are not precise, having R ² 0.60 for 1 year and 0.33 for 5 years. Considering scientists of different career ages, average R ² values for researchers having 20–36 years of experience were 0.99. For the researches having different h-index values, researchers having low h-index were difficult to predict. Parameters set comprising of current h-index, average citations per paper, number of coauthors, years since publishing first article, number of publications, number of impact factor publications, and number of publications in distinct journals performed better than all other combinations.     

The combined effect of public profiling and quality improvement efforts on heart failure management

BACKGROUND: A before-and-after study was conducted to examine the combined effect of public profiling and quality improvement activities on management of heart failure (HF) in the hospital setting. METHODS: Thirty-one hospitals in southeastern Michigan participated in this profiling and quality improvement study. One hospital closed after the baseline measurement. Two quality indicators were developed to evaluate the key processes of HF care, and one profiling indicator was designed for public profiling. The baseline results of the profiling indicator were publicly released. The individual hospitals were identified in the profiling report by name as "having statistically higher (or lower) rates than average." Remeasurement results were compared to the baseline results by using t-tests for the individual hospitals and all 30 hospitals as an aggregate. RESULTS: Two-thirds of the hospitals improved ejection fraction documentation; the aggregate result improved 5.4 percentage points (p < 0.05). No change was observed in the aggregate measure of prescribing angiotensin-converting enzyme inhibitors (ACEIs) to eligible HF patients at discharge. Hospitals with low baseline rates made improvement in ACEI use at discharge, but those with good baseline performance tended to decline in performance. There was a 2.2 percentage point increase (p < 0.05) in the profiling indicator. SUMMARY AND CONCLUSIONS: There seemed to be differential impacts of interventions across indicators and hospitals. Public profiling may have the most positive impact on hospitals with low performance at baseline. Maintaining the baseline good practice was a struggle for hospitals with relatively high baseline rates.     

Selecting quality improvement projects and product mix together in manufacturing: an improvement of a theory of constraints-based approach by incorporating quality loss

The quality of products and processes needs to be improved continuously in today's competitive environments. Unless these improvement efforts are focused properly, companies might not achieve desirable results in terms of sales, quality and productivity. Many quality improvement (QI) approaches have a limited evaluation of the factors involved in the selection of QI projects. Theory of constraints (TOC) has been proposed by some researchers as a remedy for the better selection of QI projects. However, these TOC-based approaches do not accurately capture ongoing product quality and its long-term effects on sales. Quality loss, on the other hand, can be used as a measure of customer dissatisfaction, which in turn determines the sales. The paper proposes an improvement of a TOC-based algorithm by incorporating quality loss with it. Using two simple manufacturing examples, it demonstrates that quality losses affect the product mix and QI project selection. It provides suggestions for further research directions for wider applicability of the proposed approach.
