Abstract
This paper introduces a modified single linkage clustering heuristic (MOD‐SC). The proposed MOD‐SLC objective is to test the application of Baroni‐Urban and Buser (BUB) similarity coefficient to the manufacturing cell formation (MCF) problem instead of Jaccard’s similarity coefficient. The MOD‐SLC has been compared and evaluated against three cluster formation‐based heuristics for MCF. The three heuristics are: the single linkage clustering, enhanced rank order clustering, and direct clustering algorithm. The MCF methods considered in this comparative and evaluative study belong to the cluster formation approach of solving the MCF problem. The comparison and evaluation are performed using four published performance measures. A total of 25 published and ten hypothetical and randomly generated problem data sets are used in the proposed evaluative study. Results analysis is carried out to test and validate the proposed BUB based MOD‐SLC. Finally the pros and cons of each method are stated and discussed.

Abstract
Purpose
The purpose of this paper is to draw a map of the general features of epistemological and critical concerns in contemporary Islamic philosophy. This study will not be confined to the domain of academic philosophy or to those who are professionals in the field of philosophy.
Design/methodology/approach
The paper adopted the critical rational approach in dealing with contemporary Islamic philosophy in the Arab world. The scope will include scholars from different fields of epistemology who tried to present a “vision” of the attitude that should be adopted in facing the challenges of the age and the problems of the nation on the epistemological level or the political, economic and social levels.
Findings
There is a need for a philosophy of action and progress rather than a philosophy that is based on abstract ideas and theories and of words/rhetoric. The ethics required to accomplish this ought to identify the attributes of the citizen who can reach self-actualization through legitimate means based on a progress agenda with theoretical and philosophical foundations.
Research limitations/implications
Because a critical rational approach can be dealt with from different perspectives, this paper will adopt the classification of the principal intellectual trends: the reformist, secular and liberal.
Practical implications
This paper covers a long time span to determine whether the philosophical projects have been effective.
Originality/value
This paper, which criticizes the philosophic projects that are theoretically unsound and that do not address real social problems (like poverty), argues the need for a philosophy of progress and action. This will lead to devising an agenda that addresses the challenges the society is facing and to finding alternative and creative solutions resulting in development.

Abstract
Purpose
The purpose of this study is the same as those of the preceding 16 studies on happiness, health and religion, and they are as follows: to estimate the mean scores and the sex-related differences in the study scales; to examine the associations between the study scales; to investigate the principal components; and to compare the present results with the previous findings.
Design/methodology/approach
A non-probability sample of university students in the United Arab Emirates was selected by the “snowball” sample method. To overcome the issue of people refusing to participate in the study, this method was used in the selection process due to the challenge of sampling students in all the universities across the nation, which makes it difficult to choose a probability sample. The approval of the Ethics Committee was obtained from Ajman University to apply the study tools, and then the students were given the choice through open announcement to participate in the study and circulate it to other students at Ajman University.
Findings
Results showed that men had significantly higher mean ratings on mental health, physical health and happiness than did women. All the Pearson correlations between the scales were significant for men. Except for the correlations between religiosity and both happiness and mental health, all correlations between the scales for women were significant. A principal components analysis extracted one component for men which was labeled “Well-being and religiosity”, whereas two components were retained for the women which were labeled “Well-being” and “Religiosity and physical health”. Comparing the present sample’s mean happiness score to that of prior students from 16 other countries revealed that it was higher and consistent with other scores from rich Arab nations with a high GDP per capita (such as Qatar, Kuwait, Saudi Arabia and Oman). In conclusion, happiness was found to be associated with mental and physical health in both men and women, as well as religiosity in men.
Research limitations/implications
Despite the strengths of the current investigation, i.e. the large sample size and the good to high reliability and validity properties of the scales, some limitations have to be acknowledged. First, the convenience and non-probability sample. Second, university students are a special segment of any country. Their age range is limited, and they probably have greater intelligence and more education compared to the general population. Therefore, a replication of the present study using a probability sample from the general population is needed.
Practical implications
SPSS (2009) was used for data analysis. Means, standard deviations, t-tests, d for effect size, Pearson product moment correlation coefficients and principal components analysis were used. For the principal components analysis, the Kaiser criterion (i.e. eigenvalue > 1.0) and the scree plot were used to define the number of components to be retained.
Originality/value
To the best of the authors’ knowledge, this is the first study about happiness in United Arab Emirates.
