A New Approach For Considering A Dual-Role Factor In Data Envelopment Analysis, Abdollah Noorizadeh, Mahdi Mahdiloo, Reza Farzipoor Saen

The conventional data envelopment analysis models deal with dualrole factor as non-discretionary (uncontrollable) factor. However, there might be dual-role factor which is under control of decision-maker. In addition, despite the fact that there are several publications addressing dual-role factors, it seems that their idea of classifying a factor as an input or an output within a single model has a limitation. They also do not consider non-zero input and output slacks and cannot fully measure the inefficiency of decision-making units. To resolve these limitations and to consider dual-role factor as well, this paper proposes a slacks-based measure model which does …

Supplier evaluation and selection problems are inherently multi-criteria decision problems. Numerous analytical techniques ranging from simple weighted scoring to complex mathematical programming approaches have been proposed to solve these problems. Data Envelopment Analysis (DEA) has been used to evaluate suppliers' performance when there are multiple inputs and outputs in the supplier selection problem. The DEA determines the relative efficiencies of multiple suppliers. These relative efficiencies are then used to provide benchmarking data for reducing the number of suppliers. The DEA models used for supplier selection require numerical data for all the inputs and outputs for all the suppliers. However, this …
A Data Envelopment Analysis Model For Selecting Suppliers In The Presence Of Both Dual-Role Factors And Non-Discretionary Inputs, Abdollah Noorizadeh, Mahdi Mahdiloo, Reza Farzipoor Saen

Supplier selection is the strategy adopted by the manufacturer, to evaluate and select suppliers, which can fulfil the requirements of the manufacturer. To this end, data envelopment analysis (DEA), as a multiple criteria decision-making tool, has been applied for several times. However, conventional DEA models cannot simultaneously consider dual-role and non-discretionary factors. The objective of this paper is to propose a DEA model for ranking suppliers in the presence of both dual-role factors and non-discretionary inputs. A numerical example demonstrates the application of the proposed model. 2012 Inderscience Enterprises Ltd.
Parent's Conception And Experience Of Calling In Child Rearing: A Qualitative Analysis, Justin C. Coulson, Lindsay G. Oades, Gerard J. Stoyles
Parent's Conception And Experience Of Calling In Child Rearing: A Qualitative Analysis, Justin C. Coulson, Lindsay G. Oades, Gerard J. Stoyles

The concept of "calling" has evolved from a religiously oriented description of occupation to an integrated, broad, and multidimensional construct that is associated with optimal vocational outcomes, personal fulfillment and meaning, and contribution to the "greater good." This article investigates the relevance of calling in the parental domain and explores the experience of calling in child rearing. Using interpretative phenomenological analysis, 11 qualitative, semistructured interviews were conducted with mothers and fathers. Different parents were interviewed at three distinct developmental time points in their child(ren)'s lives: while their child was an infant (<2 >years), while their children were of primary school …
