Abstract
Fancy multicount yarn (9.5s Ne) is prepared on a ring frame with an Amsler fancy yarn attachment per the Box-Bhenken design for three variables and at three levels. The ring frame process parameters selected are spindle speed, traveller mass and twist multiplier. Different yarn properties, such as yarn tenacity, breaking elongation, yarn irregularity, yarn hair index, imperfections and thin places -40% are tested. An analysis of the result is done by using statistical software. It is observed that a 9000 rpm spindle speed with a 5 twist multiplier gives maximum yarn tenacity, a 9000 rpm spindle speed with traveller mass of 120 mg gives minimum yarn irregularity and traveller mass of 120 mg with a 4.8 twist multiplier gives minimum yarn imperfections within the experimental zone explored.

Abstract
Purpose
No study was published about the tensile properties of different sections of multicount yarn. Hence there was a need to conduct a detailed section-wise tensile study of fancy multicounty yarn. The purpose of this study is to identify the different sections of the same multicount yarn and test them separately.
Design/methodology/approach
Multicount yarn with slubs were prepared on a ring frame with the Amsler Textile Effect System. Different yarn sections from each multicount yarn are identified as fine normal, fine slub, medium normal, medium slub, coarse normal, coarse slub and the changeover sections. These sections are tested for the breaking load and breaking elongation. Broken ends of the yarn sections are also studied, and these broken ends are classified as sharp broken end, tapered broken end and slipped broken end. A study is also conducted on the location of break or the place of break at the changeover sections.
Findings
It was found that the twist of yarn at slub sections was lower than the twist at normal sections. In spite of the low yarn twist at slub sections, the breaking load of the yarn was higher at slub sections than at normal sections by 12 to 30 per cent owing to the presence of more number of fibres that share the breaking load. The breaking load at the changeover section (normal to slub and slub to normal) was found to be higher than that at normal section and lower than at slub sections. No significant difference was found between the breaking load of the two changeover sections (normal to slub and slub to normal). The majority of breaks in normal yarn sections were of the tapered broken end type and the majority of breaks in slub yarn sections were slipped broken ends.
Originality/value
Efforts are taken to identify different sections of the same multicount yarn with the help of specially designed square black board and tensile study of these sections are carried out.

Abstract
Purpose
Hospitality firms aim to increase their profits by implementing a variety of marketing activities, including using decoy pricing to provide alternative choices for consumers. Decoys are relatively higher-priced offerings that signal lower value than the other offerings in the consideration set. The purpose of this research is to investigate the influence of decoy pricing on consumer choices across various contexts in the foodservice and hotel industries.
Design/methodology/approach
Across the pilot and four main studies, the current research employs a sequential exploratory mixed-method design to investigate the influence of decoy pricing in the foodservice and lodging industries. The qualitative part of this research was based on two focus groups, followed by a pilot study and four main study experiments.
Findings
The results show that decoy pricing escalates consumers’ choices of more expensive product bundles in both restaurant and hotel cancellation policy contexts. However, decoy pricing does not increase the selection of more expensive hotel product bundles.
Originality/value
While decoy pricing has been utilized as an effective revenue maximization strategy for product placement in retail stores, less is known about how promotional advertisements with decoy offers influence hotel and restaurant customers to choose more costly options. Specifically, this is the first study that explores whether decoy pricing and product/service bundling can encourage customers to select more expensive offers in hotel and restaurant contexts, considering the types of hospitality bundles that may limit this effect.

Abstract
Purpose
The purpose of this paper is to identify the input, process and output factors (along with their manifest variables) of small and medium enterprises (SMEs), and to establish cause and effect relationships amongst the factors and sub-factors. Systems thinking, a holistic approach, is used to carry out qualitative analysis of the feedback loops.
Design/methodology/approach
A well-structured questionnaire was developed to gather the relevant data to identify the factors affecting the performance of SMEs in a holistic manner. A total of 150 responses were collected during November 2015–March 2016. Factor analysis and path analysis were used to establish causal relationships between input, process and output factors. The systems thinking approach has been used for qualitative analysis.
Findings
Feedback loops have been identified amongst input-process-output-input factors and amongst sub-factors. They enabled authors to infer that the managers/owners of SMEs are systems thinkers, if not completely, at least partially. Six negative feedback loops and one positive feedback loop prevail. System behaviour arises out of the interaction of positive and negative feedback loops; it appears that in the long-run, the SMEs attain their target levels. The following inferences are drawn: circular relationships are identified amongst input, processes and organisational performance (OP), modern management tools such as just in times, Kanban have long-term benefits and are perceived as ineffective by small enterprises and formal financing and functional transparency enhances OP.
Originality/value
Systems thinking, a holistic approach, has been used to study the effect of input, process and output factors on one another. Such studies are sparse, especially, in the Indian context. Many studies have been conducted to study the effect of input and of processes on performance such as innovation, information technology, human resource, technology, government regulation on performance of SMEs in a silo but, rarely all together. The qualitative analysis adds value to the research. Many of the outcomes of the research have been largely discussed in Indian print media which indicates the pragmatic approach of the research.
