The study aims to design a control chart based on an exponentially weighted moving average (EWMA) chart of Pearson's residuals of a model of negative binomial regression in order to detect possible anomalies in mortality data.

In order to evaluate the performance of the proposed chart, the authors have considered official historical records of death of children of Ecuador. A negative binomial regression model was fitted to the data, and a chart of the Pearson residuals was designed. The parameters of the chart were obtained by simulation, as well as the performances of the charts related to changes in the mean of death.

When the chart was plotted, outliers were detected in the deaths of children in the years 1990–1995, 2001–2006, 2013–2015, which could show that there are underreporting or an excessive growth in mortality. In the analysis of performances, the value of λ = 0.05 presented the fastest detection of changes in the mean death.

The proposed charts present better performances in relation to EWMA charts for deviance residuals, with a remarkable advantage of the Pearson residuals, which are much easier to interpret and calculate. Finally, the authors would like to point out that although this paper only applies control charts to Ecuadorian infant mortality, the methodology can be used to calculate mortality in any geographical area or to detect outbreaks of infectious diseases.

The purpose of this paper is to observe how to invest in upper-middle income countries via an innovation perspective following global innovation index (GII) by multicriteria decision aid (MCDA) approach, once MCDA was designed to support subjective decisions.

Pearson’s correlation was the milestone for understanding innovation indicators at upper-middle income countries profiles. In a MCDA first step, the analytical hierarchy process (AHP) was applied to obtain the criteria weight. In this step, the judgments or evaluations inputted in AHP were collected from a sample composed by five experts in GII. After getting the criteria weights compose to GII, Borda and Preference Ranking Organization Method for Enrichment Evaluations (PROMÉTHÉE) methods were applied to obtain an MCDA-based GII. The inputs for this second step were: the weights come from AHP output; and the countries performance came from GII data.

As a result, it was found out the upper-middle countries’ rank to invest and groups with countries acting like “hubs” or “bridges” for economic sectors in near countries; when they are grouped according to their maximum and minimum scores profiles, observing not only a particular region but also similar profiles at diverse world areas.

Pearson-AHP-PROMÉTHÉE works as a supportive decision tool for several and complex investment perspectives from criteria and alternatives analysis regarding innovation indicators for upper-middle income countries. This combination also demonstrates grouping possibilities, aligning profiles and not only ranking countries for investment and eliminating others but also grouping countries with similar profiles via innovation indicators MCDA combined application.

The purpose of this paper is to examine academics’ awareness of and attitudes towards Wikipedia and Open Access journals for academic publishing to better understand the perceived benefits and challenges of these models.

Bases for analysis include comparison of the models, enumeration of their advantages and disadvantages, and investigation of Wikipedia's web structure in terms of potential for academic publishing. A web survey was administered via department-based invitations and listservs.

The survey results show that: Wikipedia has perceived advantages and challenges in comparison to the Open Access model; the academic researchers’ increased familiarity is associated with increased comfort with these models; and the academic researchers’ attitudes towards these models are associated with their familiarity, academic environment, and professional status.

The major limitation of the study is sample size. The result of a power analysis with GPower shows that authors could only detect big effects in this study at statistical power 0.95. The authors call for larger sample studies that look further into this topic.

This study contributes to the increasing interest in adjusting methods of creating and disseminating academic knowledge by providing empirical evidence of the academics’ experiences and attitudes towards the Open Access and Wikipedia publishing models. This paper provides a resource for researchers interested in scholarly communication and academic publishing, for research librarians, and for the academic community in general.

The purpose of this paper is to present a P2P network security pricing model that promotes more secure online information sharing in P2P networks through the creation of networks with increased resistance to malicious code propagation. Online information sharing is at an all‐time high partly due to the recent growth in, and use of, online peer‐to‐peer (P2P) networks.

The model integrates current research findings in incentive compatible network pricing with recent developments in complex network theory. File download prices in P2P networks are linked to network security using a graph theory measurement called the Pearson coefficient. The Pearson coefficient indicates a structural dimension of scale‐free networks (scale‐free networks like the internet) called preferential attachment. Preferential attachment refers to the network property where the probability for a node to connect to a new node is greater if the new node already has a high number of connections.

The P2P network security pricing model concept is illustrated to show how the model functions to create more secure P2P networks.

Future research in P2P network security pricing should focus on testing the model presented in this paper by numerical experiments and simulation including the tracking of malicious code propagation on networks grown under the pricing model.

The P2P network security pricing model demonstrated here is a different approach to network security that has a strong potential to impact on the future security of P2P and other computer based networks.

This study aims to apply a systematic statistical approach, including several plot indexes, to diagnose the goodness of fit of a logistic regression model, and then to detect the outliers and influential observations of the data from experimental data.

The proposed statistical approach is applied to analyze some experimental data on internal solitary wave propagation.

A suitable logistic regression model in which the relationship between the response variable and the explanatory variables is found. The problem of multicollinearity is tested. It was found that certain observations would not have the problem of multicollinearity. The P‐values for both the Pearson and deviance χ² tests are greater than 0.05. However, the Pearson χ² value is larger than the degrees of freedom. This finding indicates that although this model fits the data, it has a slight overdispersion. After three outliers and influential observations (cases 11, 27, and 49) are removed from the data, and the remaining observations are refitted the goodness‐of‐fit of the revised model to the data is improved.

A comparison of the four predictive powers: R², max‐rescaled R², the Somers' D, and the concordance index c, shows that the revised model has better predictive abilities than the original model.

The goodness‐of‐fit and prediction ability of the revised logistic regression model are more appropriate than those of the original model.

The purpose of this paper is twofold. First, the study aims to investigate the relationship between the altmetric indicators from ResearchGate (RG) and the bibliometric indicators from the Scopus database. Second, the study seeks to examine the relationship amongst the RG altmetric indicators themselves. RG is a rich source of altmetric indicators such as Citations, RGScore, Impact Points, Profile Views, Publication Views, etc.

For establishing whether RG metrics showed the same results as the established sources of metrics, Pearson’s correlation coefficients were calculated between the metrics provided by RG and the metrics obtained from Scopus. Pearson’s correlation coefficients were also calculated for the metrics provided by RG. The data were collected by visiting the profile pages of all the members who had an account in RG under the Department of Physics, Panjab University, Chandigarh (India).

The study showed that most of the RG metrics showed strong positive correlation with the Scopus metrics, except for RGScore (RG) and Citations (Scopus), which showed moderate positive correlation. It was also found that the RG metrics showed moderate to strong positive correlation amongst each other.

The limitation of this study is that more and more scientists and researchers may join RG in the future, therefore the data may change. The study focuses on the members who had an account in RG under the Department of Physics, Panjab University, Chandigarh (India). Perhaps further studies can be conducted by increasing the sample size and by taking a different sample size having different characteristics.

Being an emerging field, not much has been conducted in the area of altmetrics. Very few studies have been conducted on the reach of academic social networks like RG and their validity as sources of altmetric indicators like RGScore, Impact Points, etc. The findings offer insights to the question whether RG can be used as an alternative to traditional sources of bibliometric indicators, especially with reference to a rapidly developing country such as India.

The purpose of the study is to investigate the correlation between credit supply to government and credit supply to the private sector to determine whether there is a crowding-out or crowding-in effect of credit supply to government on credit supply to the private sector.

The study used data from 43 countries during the 1980–2019 period. The study employed the Pearson correlation methodology to analyze the data.

There is a significant positive correlation between credit supply to government and credit supply to the private sector. There is also a significant positive relationship between credit supply to government and credit supply to the private sector, implying a crowding-in effect of government borrowing on private sector borrowing. The positive correlation between credit supply to government and credit supply to the private sector by banks is stronger and highly significant in the period before the Great Recession, while the positive correlation is weaker and less significant during the Great Recession, and the correlation further weakens after the Great Recession. The regional analyses show that the positive correlation between credit supply to government and credit supply to the private sector by banks is stronger and highly significant in the African region than in the Asian region and the region of the Americas.

There is no evidence on the correlation between credit supply to government and credit supply to the private sector during the Great Recession.

In order to succeed in an action under the Equal Pay Act 1970, should the woman and the man be employed by the same employer on like work at the same time or would the woman still be covered by the Act if she were employed on like work in succession to the man? This is the question which had to be solved in Macarthys Ltd v. Smith. Unfortunately it was not. Their Lordships interpreted the relevant section in different ways and since Article 119 of the Treaty of Rome was also subject to different interpretations, the case has been referred to the European Court of Justice.

The purpose of this paper is to examine the effects of workplace incivility on job satisfaction and employees’ turnover intentions in Indian work settings.

Data were collected randomly from 283 employees at various restaurants in the Northern and Western parts of India via the survey method and, thereafter, hierarchical regression analysis was performed to analyze the data.

The study established that moderate to high levels of workplace-incivility-related issues are present in India’s restaurant industry. Regression analysis further revealed that workplace incivility is negatively related to job satisfaction and positively related to employee turnover in the Indian context as well.

Relevant recommendations are presented to restaurant owners as well as HR practitioners that could curb unethical practices in Indian restaurants and promote civil behavior in the workplace.

Relevant extant studies have recognized that there is a need to study workplace incivility in different cultures to establish the global relevance of the subject. This research studied the impact of workplace incivility on job satisfaction and turnover intentions with respect to Indian employees.

The purpose of this paper is to examine empirically the link between the determinants of perceived strategic value (PSV) of e‐commerce and e‐commerce adoption among Ghanaian small and medium size enterprises (SMEs), defined as businesses that employ a maximum of 200 employees.

The authors randomly sampled SME owners/managers from the membership of the Ghana Club 100 (GC 100) and non‐traditional exporters (NTEs). Established databases are not the norm in Ghana, and GC 100 and NTEs had membership databases that were accessible to the local co‐author. Investigating e‐commerce adoption issues among these companies was warranted. The authors used a structured instrument developed and validated in prior studies to collect the data in a face to face interview. A pilot study was conducted to ascertain the clarity and reliability of the questionnaire. Of the SME owners/managers: 200 were contacted; 112 agreed to participate in the study; 107 responses were obtained – representing a 53.5 per cent response rate. Statistical analysis was performed using SPSS 14.

Factor analysis demonstrated convergent and discriminant validity and construct reliability. PSV construct resulted in four factors: Strategic Decision Support (SD), Information Management (IM), Organizational Support (OS) and Decision Aids (DA). This finding is both consistent and inconsistent with prior research. The adoption construct yielded five factors: Perceived Usefulness (PU), Ease of Use (EU), Compatibility (C), Organisational Readiness (OS) and External Pressure (EP). There was more congruence between our results and those of prior research.

Limitations stem from small sample size, the population and locale from which the sample was drawn.

The study has research and practical implications, and these are discussed fully in the paper.

The paper contributes to the knowledge of perceived strategic value and adoption of e‐commerce by SMEs in an under‐researched part of the world.
