Abstract

Purpose

The purpose of this paper is to develop and implement methods for benchmarking the food safety and hygiene between retail outlets at the same time or at the same retail outlets at different times.

Design/methodology/approach

A tailor made questionnaire for the collection of food safety and hygiene remarks was designed to be applied in a large chain of retail outlets. The remarks were classified in the five categories of the Ishikawa model (materials, methods, personnel, equipment and environment). The retail outlets were located all over Greece and the audits were performed in a one-year term. Food safety experts were used as auditors after a six-month training period. The data collected were subject to analysis of the benchmarking scores and to cluster analysis to identify regions with similar food safety profiles.

Findings

Polar charts were used to illustrate the benchmarking scores for each of the five categories of evaluation per auditing period at the retail outlets. Another polar chart illustrates the benchmarking scores for each of the 12 regions of Greece. Cluster analysis demonstrates that some regions, like Ionian Islands and South Aegean, have similar profiles on food safety for the retail outlets.

Originality/value

The developed methodology can be used by retail companies with several outlets or by a group or an association of companies in order to identify problematic sectors and to set priorities while dealing with issues of food safety and hygiene. The work is limited to the Greek outlets but the methodology has potential application to every other country.

Abstract

Purpose

The purpose of this paper is to develop and implement benchmarking methods on food safety and hygiene between suppliers of fruits and vegetables, regardless the food safety management systems they implement.

Design/methodology/approach

A tailor made questionnaire was prepared of 64 questions, divided into ten sectors regarding hygiene and food safety. The suppliers were selected from the inventory of a large chain of retail stores. The audits were performed by a food safety expert on the site of the company. Totally, 72 audits were conducted in several geographic regions of Greece. The data collected was statistically analyzed for benchmarking with technical, geographical or financial criteria.

Findings

The large size companies have a level from satisfactory to very satisfactory in the transport and need improvement on their packaging materials. Improvement in procedures of cleaning and disinfection is required by companies which are in the region of Attica and the Peloponnese.

Originality/value

The proposed methodology and analysis can be used to benchmark groups of food companies with common commercial profile in order to prioritize both the frequency of audits and the importance of interventions and preventive measures.

Abstract

Purpose

The purpose of this paper is to present an approach to a polar graph measurement by a flight testing technique and to propose a baseline research method for future tests of UAV polar graphs. The method presented can be used to demonstrate a conceptual and preliminary design process using a scaled, unmanned configuration. This shows how results of experimental flight tests using a scaled flying airframe may be described and analysed before manufacturing the full scale aircraft.

Design/methodology/approach

During the research, the flight tests were conducted for two aerodynamic configurations of a small UAV. This allowed the investigation of the influence of winglets and classic vertical stabilizers on the platform stability, performance and therefore polar graphs of a small unmanned aircraft.

Findings

A methodology of flight tests for the assessment of a small UAV’s polar graph has been proposed, performed and assessed. Two aerodynamic configurations were tested, and it was found that directional stability had a large influence on the UAV’s performance. A correlation between the speed and inclination of the altitude graph was found – i.e. the higher the flight speed, the steeper the altitude graph (higher descent speed, steeper flight path angle). This could be considered as a basic verification that the recorded data have a physical sense.

Practical implications

The polar graph and therefore glide ratio of the aircraft is a major factor for determining its performance and power required for flight. Using the right flight test procedure can speed-up the process of measuring glide ratio, making it easier, faster, robust, more effective and accurate in future research of novel, especially unorthodox configurations. This paper also can be useful for the proper selection of requirements and preliminary design parameters for making the design process more economically effective.

Originality/value

This paper presents a very efficient method of assessing the design parameters of UAVs, especially the polar graph, in an early stage of the design process. Aircraft designers and producers have been widely performing flight testing for years. However, these procedures and practical customs are usually not wide spread and very often are treated as the company’s “know how”. Results presented in this paper are original, relatively easily be repeated and checked. They may be used either by professionals, highly motivated individuals and representatives of small companies or also by ambitious amateurs.

Abstract

Purpose

The purpose of this paper is to introduce the IC Rating™ approach as a management consulting approach to measure intellectual capital and to report on the implementation and experience in one case study firm.

Design/methodology/approach

The paper describes the IC Rating™ model in the context of the exiting literature in the field of IC measurement and uses a case study to demonstrate its practical application.

Findings

Based on the presented case study as well as implementations in other organizations we find the IC Rating™ model a useful tool to facilitate the analysis and discussion about intellectual capital in organizations.

Practical implications

The article gives a complementary view to the most commonly used score card methods and guidelines for intangibles on how intangibles can be measured. IC Rating™ focuses on the comparability between companies and industries as well as a simplification of how to interpret intangible measures.

Originality/value

The original idea for the paper was to answer the question “Why do companies really need to measure and develop intangibles?”. The answer is “To improve company financial performance”. The IC Rating™ methodology is therefore based on the answers to two other questions: “Which parameters does an executive manager need to have insightful knowledge of, in order to make the right decisions for the future?” and “From where and whom should the executive manager receive this information?”.

Abstract

The pressure control valve is a possible means of overcoming the effects of compliance between a hydraulic servo and its load. The valve consists of two stages; an open‐centre flow control valve schematically analogous to a resistance bridge, and a split‐slider valve. In order to study the dynamics of the system it is convenient to set up an electrical analogue for the mechanical system. This will give the non‐linear equations of the system. Several forms of the various impedance elements making up the system require consideration. The resistance of a length of hydraulic line can be obtained from the friction factor and will depend on the flow regime which prevails. In developing an expression for the inductance of a length of line the assumption is made that the wavelength of the oscillatory motion is long compared with the line length. In considering the resistance of orifices it is necessary to take into account the three regimes for flow through an orifice, laminar, transition, and turbulent flow. The inductive effect of an orifice arises from the acceleration of the fluid as the streamlines converge through the orifice; an expression can be derived by applying Newton's second law of motion to the column of oil passing through the orifice. The effective capacitance of a volume can be derived by considering wave motion in one dimension. An expression for the radiation resistance of a piston is derived, and also one for the incident and reflected waves. In constructing the electrical analogue for the slider valve the mass and viscous damping of the slider as well as Bernoulli forces must be represented.

Abstract

A range of 5 basic types of industrial, all purpose, relays offer a choice of ac or dc coils ‐6A capacity. Operating at 2·4VA for ac and 1·2W dc, the D range conforms with accepted coil power requirements. High impact flame retardant moulding materials, with good insulation properties, are used throughout. Plug‐in types, with either solder or screw‐terminal sockets and panel mounted types suitable for either termination or Faston connectors, are both supplied with a clear polycarbonate clip‐on dust cover. A narrow profile of both the 2 pole and 3 pole plug‐in versions enables close stacking and consequently space saving with additional uniformity of appearance when mounted on an equipment panel.

Abstract

The Industrial Training Act, and the Industry Training Boards which the Act created, have caused a dramatic increase in training activities in Britain. There has been a focusing of attention on to the need to improve the organisation, administration and management of training. There has, however, been less attention given to the need to create the correct environment in which in‐plant training, courses and lectures may be carried out. Accommodation, furniture, fixed and movable equipment all make an important contribution to the correct environment for both student and teacher; a correct choice can have a marked effect on the efficiency and effectiveness of a training department.
