Abstract

In the last four years, since Volume I of this Bibliography first appeared, there has been an explosion of literature in all the main functional areas of business. This wealth of material poses problems for the researcher in management studies — and, of course, for the librarian: uncovering what has been written in any one area is not an easy task. This volume aims to help the librarian and the researcher overcome some of the immediate problems of identification of material. It is an annotated bibliography of management, drawing on the wide variety of literature produced by MCB University Press. Over the last four years, MCB University Press has produced an extensive range of books and serial publications covering most of the established and many of the developing areas of management. This volume, in conjunction with Volume I, provides a guide to all the material published so far.

Abstract

During the recent strike wave, Britain and other industrial market economies experienced a marked increase in the annual total number of working days lost through stoppages. A question arises, however, as to the validity of these comparisons, and the true meaning of strike statistics. There has been substantial controversy in recent years on the validity of making international comparisons of strike behaviour. All the conceptual and practical problems involved in strike statistics come to the surface when these comparisons are made. It is likely that statistics from different countries will be subject to differing national minimum definitions, and will be based on different answers to the question: What is a strike?

Abstract

Purpose

This study aims to develop sweet chestnut incorporated corn-based extrudates by the optimization of process conditions.

Design/methodology/approach

The independent process variables for extrusion (blend ratio, barrel temperature, screw speed and feed moisture) were investigated to govern their impact on reliant variables, namely, bulk density, specific mechanical energy, water absorption index, water solubility index, color and hardness. Product and system responses were significantly (p < 0.05) affected by the independent variables. Experimental design with quadratic models experienced a high coefficient of determination (R2 = 0.99).

Findings

Numerical optimization for the development of extrudates resulted in optimum conditions having corn flour: sweet chestnut flour (80:20), barrel temperature (120°C), screw speed (340 rpm) and feed moisture (12%). Fat, moisture and protein contents of the developed extrudates using optimum conditions were significantly (p < 0.05) lower compared to raw materials – corn and sweet chestnut. The packaging of extrudates in aluminum laminates revealed shelf stability of three months at room temperature without deterioration of quality.

Originality/value

Nutritionally rich sweet chestnut extruded products would be an exclusive option to already existing snacks in the market and can facilitate a new sphere in extruded product sector.

Abstract

Purpose

This study aims to evaluate the effectiveness of substituting different concentrations of sesame, soy butter, dried moringa leaves and coconut powder on the physicochemical and sensory properties especially calcium and protein content of salted and sweet cookies.

Design/methodology/approach

Cookies were prepared by fortifying refined flour with sesame (T1 and T3) and soy butter (T2 and T4) and further fortified with dried moringa leaves (salted) and coconut (sweet). Linear programing was used to formulate percentage of major ingredients to yield maximum calcium and protein. Cookies were evaluated for physical, textural, colour, nutritional, functional and organoleptic properties and compared with refined flour cookies, C1 (salted) and C2 (sweet).

Findings

It was observed that fortification significantly decreased the hardness of the test cookies when compared with control. C2 cookies were observed to be the hardest (42.3 N), whereas T2 cookies were the softest (23.7 N). Nutritional and functional components of fortified (T) cookies were significantly (p = 0.01) higher than control (C) cookies, and within T cookies, salted cookies were more nutritious than sweet cookies. Cookies fortified with sesame and dried moringa leaves (T1) contained the highest protein (19 g), calcium (312 mg) and flavonoids (2.0 QE mg/100g) content. Scores on sensory acceptability revealed that T cookies were highly acceptable when compared to cookies for all sensory attributes tested.

Research limitations/implications

Incorporation of protein and mineral rich natural ingredients like sesame, soy butter, dried moringa leaves and coconut powder has improved the nutritional, functional and sensory properties especially calcium and protein content of salted and sweet cookies. There is tremendous scope for utilisation, commercialization of such plant-based nutrient dense ingredients in variety of food snacks, and this will ensure better nutritional security.

Originality/value

Fortification of biscuits with sesame, soy butter, dried moringa leaves and coconut powder resulted in to a superior quality of biscuits in terms of its protein, minerals specially calcium, flavonoid content and organoleptic acceptability. These protein and calcium rich biscuits may help in solving many nutritional deficiencies and can add variety to the bakery industry.

Abstract

Purpose

The purpose of this study was to compare the nutrient and antinutrient content of two improved sweet potato varieties released for drought prone areas of eastern Ethiopia.

Design/methodology/approach

Matured roots of two sweet potato varieties, namely, Berkume and Adu, were collected from Haramaya University, Toni Research Farm, Ethiopia. The sweet potatoes were ground into flour following standard procedure. Thereafter, proximate, dietary minerals and β-carotene were determined by official methods of analysis. The tannin and phytate contents were determined by colorimetric methods.

Findings

The moisture, protein, fat, fiber, ash, utilizable carbohydrate and gross energy varied from 6.23-6.61 per cent, 2.07-2.76 per cent, 1.25-1.52 per cent, 1.04-1.16 per cent, 3.38- 5.32 per cent, 90.03-91.45 per cent and 382.18-388.07 Kcal/100 g in both the sweet potato varieties. Potassium content (176.17 mg/100 g) was reported to be the highest and registered in Berkume variety, while the lowest mineral content (2.18 mg/100 g) determined was zinc in Adu sweet potato variety. The highest total carotenoid content (3.39mg/100 g) was recorded in Berkume sweet potato variety. The tannin and phytic acid contents ranged from 9.98 to 12.94 mg/100 g and from 0.24 to 0.31 mg/100 g in Berkume and Adu sweet potato varieties, respectively.

Originality/value

This study showed that the Berkume sweet potato variety has high nutritional potential and less antinutrient contents as compared with the nutritional value of many other roots and tuber crops documented in the FAO database and hence can contribute to reducing malnutrition in resource-poor settings of Ethiopia. Further work needs to be carried out on developing value-added products from Berkume sweet potato variety for its extensive utilization.

Abstract

According to Truth the War Office has selected Mr. C. C. DUNCAN, F.I.C., the Public Analyst for the County of Worcester, for a special post, in which “ he will be responsible for the examination of the water supply for the troops.” “It might be supposed,” our contemporary observes, “that the services of this scientific expert would be worth at least the pay of a Captain. The War Office thinks differently. It is giving Mr. Duncan the pay of a private soldier, a piece of parsimony in no wise excused by the fact that the difference between his military pay and his regular salary will be made up by the Worcestershire County Council.” It appears that MR. DUNCAN has been selected for the post in question on the recommendation of a body described by Truth as “ The Institute of Analysts.” As no such body exists we presume that either the Institute of Chemistry or the cumbrously‐named “ Society of Public Analysts and Other Analytical Chemists” is referred to. It would be interesting to know what the Councils of either or both of these concerns have got to say about the treatment of this member of the profession which they are supposed to represent and whose dignity and interests they are supposed to maintain. The monstrous advertisement issued by the Woolwich Arsenal authorities about a year ago in which scientific chemists with University degrees were invited to apply for appointments at the munificent remuneration of £2 per week is a sufficient illustration of the value put upon scientific attainments by Government Departments in this country. But even this example of fatuous ignorance and inane parsimony has been eclipsed by the present arrangements for the employment of scientific chemists in the Royal Engineers, in which they are invited to enlist with the rank of Corporal and with Corporal's pay and “allowances.” The sulphuric acid scandal recently exposed by The Globe makes it once more abundantly clear that where scientific advice even of an elementary kind is needed no attempt is made to obtain reliable guidance. The wrong people are invariably applied to for advice and the wrong men are appointed to fill responsible posts. The following remarks appear in The Globe of September 23rd :—“We have evidence of the incompetence of the High Explosives Department which thought it fitting to appoint as the comptroller of the shipment of oleum” (i.e., a form of sulphuric acid shipped from America) “a young man, wholly inexperienced, at a handsome salary, his only qualification apparently being that he was the son of his father. This young man was completely ignorant of the properties of oleum. His first introduction to the acid was when he was called upon to advise as to the best method of shipment.” According to the facts stated in The Globe the result of this bungling has been a loss of some hundreds of thousands of pounds to the taxpayers of this country.

Abstract

The Howard Shuttering Contractors case throws considerable light on the importance which the tribunals attach to warnings before dismissing an employee. In this case the tribunal took great pains to interpret the intention of the parties to the different site agreements, and it came to the conclusion that the agreed procedure was not followed. One other matter, which must be particularly noted by employers, is that where a final warning is required, this final warning must be “a warning”, and not the actual dismissal. So that where, for example, three warnings are to be given, the third must be a “warning”. It is after the employee has misconducted himself thereafter that the employer may dismiss.

Abstract

Purpose

This study aims to assess the quality characteristics and acceptability of cookies from sweet potato–maize flour blends and to determine nutritional quality, color and palatability traits and to compare the effects with that of wheat cookies, so as to suggest a cost-effective production method to bakers and retailers. This would ensure food security, enhanced health, combat malnutrition problems and improve the production of the crops.

Design/methodology/approach

Cookies were prepared by the method reported by Okaka and Isieh (1990), Abayomi et al. (2013), Onabanjo and Ighere (2014) with modification. Flour (200 g) from each sample of different flour blends was used for the experiment. Sugar (80 g) was creamed with margarine (100 g) until light and fluffy constituency was obtained using Kenwood chef with initial minimum speed, and the speed increased stepwise until the mark of 6 on the chef indicator was attained. Whole egg (60 g) was added, then followed by flour (200 g), powdered milk (20 g), baking powder (0.1 g) and salt (1 g) were added and mixed until a stiff paste (batter) was obtained. The batter was rolled on a floured board using a rolling pin to a thickness of 0.2-0.3 cm. The rolled batter was cut into circular shapes with a cutter and arranged on a greased tray and baked at 1500°C for 20 minutes. The cookies were brought out, cooked and packaged in cellophane bag until used for laboratory analysis.

Findings

The results revealed that substitution of sweet potato flour with maize flour significantly (p < 0.05) reduced the protein from 6.8-4.4 per cent, moisture from 5.3-5.0 per cent, crude fibre from 3.4-2.5 per cent and fat from 9.8-8.5 per cent of the composite flours and the cookies. The ash and sugar contents were increased from 4.3-5.8 per cent for ash and 2.1-3.9 per cent for sugar with increase in sweet potato flour substitution. The calorific value of the cookies decreased from 457-397 cal/100 g as the percentage of sweet potato flour increased in the maize flour cookies. Sensory evaluation results showed that the colour, texture, taste and overall acceptability changed significantly (p < 0.05) with increase in sweet potato flour substitution. The optimum substitution level was 40 per cent; above this, the product becomes less acceptable to the consumer.

Research limitations/implications

Fabrication and production processing machines that use sweet potato will be a great challenge.

Originality/value

This research is of value to the bakery industry or retailers. The optimum substitution level of sweet potato flour was 40 per cent, and it appears to be a promising measure from the view of practicability. The relative ease of getting sweet potato flour makes it superior to other imported flour like wheat and in reducing cost of importation of wheat to Nigeria.
