The present study aims to shed some light on an old controversy about the joint impact of acquiescence and social desirability on item responses. There are two main hypotheses: (a) of the two biases, social desirability is by far the prime determinant, and (b) acquiescence operates in all sorts of items, including those impacted by social desirability. A new methodology is harnessed to assess t...

In practices, not only production but inspection processes are often not perfect, thereby generating defects and inspection errors. Previous imperfect-quality inventory studies, however, have mostly focused on developing cost-minimizing models that do not consider imperfect inspection processes and related defect sales return issues despite their practical significance. Thus, this study propose...

The heritability and stability over a 19 year period of long (23-item) and short (12-item) versions of Eysenck s Neuroticism scale were compared in a large Australian twin-family sample. Stability over 19 years of the 23-item Neuroticism scale was 0.62 and for the 12-item scale 0.59. Correlations between scores obtained by mailed questionnaire and telephone interview a few weeks apart were 0.87...

In this paper, we extend Porteus (1986) to generalize the economic production quantity (EPQ) model with finite production rate and to derive an exact expression for the expected total annual cost function when maintenance actions and capital investment in setup cost reduction are adopted. In addition, the uniqueness property of the optimal lot size and the bounds of optimal lot size are derived...

Two studies assessed the relationship between celebrity worship and (i) addiction (n 1359) and (ii) criminality (n 2158). Overall Celebrity Attitude Scale (CAS) scores correlated positively with Eysenck Personality Questionnaire Revised (EPQ-R) Addiction and Criminality sub-scale scores. In further support of the absorption addiction model of celebrity worship (McCutcheon, Lange, & Houran, 2002...

Three coefficients of factor similarity were examined with regard to their behaviour within four sets of data. Two simple methods using Pearson r correlations and Tucker Congruence coefficients were compared with a more complex method given by Kaiser. Hunka and Bianchini (1971). Three of the data sets involved the use of 100 random data matrices, the fourth was that provided by the Eysencks’ wo...

Recently, in Mathematical and Computational Applications Journal Chiu et al. [1] and Chen and Chiu [2] propose an inventory model based on EPQ with rework to determine the replenishment lot size and the number of shipments for a vendor-buyer integrated production-inventory system. They solve the inventory problem by considering both variables as continuous. However, the number of shipments must...

A single-item economic production model is developed in which inventory is depleted not only due to demand but also by deterioration. The rate of deterioration is taken to be time dependent, and the time to deterioration is assumed to follow a two-parameter Weibull distribution. The Weibull distribution, which is capable of representing constant, increasing, and decreasing rates of deterioratio...
