Training needs for women-owned SMEs in England

Originality/value – The study offers original primary research into the contributory growth factors for women-owned enterprises in a representative area of Britain, identifies key issues, maps survival and success factors, and assesses women entrepreneurs' training needs and preferences.Purpose – The purpose of this research is to investigate the needs and preferences for training among growth-oriented women-owned SMEs in the East of England. Design/methodology/approach – Quantitative data were collected through 108 on-line questionnaires, and the means analysed using SPSS. Qualitative data collected in response to open-ended questions were inductively analysed and interpreted. Findings – Only one fourth of respondents received growth-oriented training in the previous two years, with an average duration of 3-5 days per year. Programmes most in demand concerned innovation and opportunity recognition, business evaluation and growth considerations, developing strategic customers and customers care, customer relationship management, as well as selling, networking and negotiation skills. High demand for these programmes corresponds to others results identifying contributory factors to higher enterprise performance and growth: product/service quality, new product/service development, appropriate marketing, effective use of websites, selling skills and informal networking. Research limitations/implications – The scope of the project is limited to service sectors and sole proprietorships. Geographic scope is limited to the East of England. These limits nonetheless provide a reasonable base and rationale for the scope of the study. Practical implications – With a better understanding of the capacity building requirements of women entrepreneurs in growth businesses, appropriately designed training programmes can be developed to help women achieve higher levels of entrepreneurial success

Creel Census of Des Moines River Fishermen in Boone, Dallas, and Polk Counties, Iowa

Creel censuses were conducted on the Des Moines River during the open water seasons, usually April through November, from 1953 through 1961. The data indicated a relatively constant catch of fish. The rate of annual catch varied between a minimum of 0.26 and a maximum of 0.61 fish per fisherman-hour. The data were also analyzed by proficiency categories involving (1) all fishermen, (2) fishermen with one fish, (3) fishermen with two fish, and (4) fishermen with three or more fish. The most proficient fishermen (those with three or more fish at the time of interview) constituted l3 per cent of all anglers, and caught 65 per cent of all fish. The average length of the angler day for the census period was 2.3 hours. Channel catfish, carp, bullheads, and walleye pike, in that order, were the important fish taken. Fisherman aptitude or skill is concluded to be the significant factor related to both the catch of fish and the rate at which they are caught

Returns From Tagged Channel Catfish In the Des Moines River, Iowa

The Channel Catfish was shown by Speaker (1948) in a sample of 1800 Iowa anglers to be the most important species of fish inhabiting the inland streams of Iowa. Therefore, any information concerning its life history and habits is important and of value in formulating a management policy for the species. To get information on the life history and habits of the channel catfish, tagging experiments were initiated in 1947. Tagging was carried on through 1949 and recoveries are continuing. The information sought by this investigation was: (1) to study the possibility of using marked fish for an inventory of stream populations of channel catfish, (2) to determine the extent of movements of catfish in Iowa\u27s inland streams, and (3) to secure factual information relative to the rate of growth of catfish in what is presumed to be good catfish habitat. The purpose of this paper is to record the information gathered to date and to discuss the value of the methods employed as instruments for studying the channel catfish

Investigations of generic self disassembly using shape memory alloys

Industrial recycling is a practice of growing importance while impending `Take Back' European legislation and economic pressures are increasing. Landfill sites are becoming exhausted and the industry could benefit from a novel approach to recycling pre and post consumer waste. Cost constraints limit the number of different products that can be recycled. Recyclers are working on broadening the range of reusable components from this waste stream, but the proposed approach would significantly increase the volume of recyclable material used in manufacturing new products. This alternative could potentially reduce recycling cost per product in the event of mandatory recycling as a wide variety of consumer electronics could be actively or self disassembled on the same generic dismantling line. The use of Shape Memory Alloy (SMA) actuators in a wide variety of consumer electronic products in the same dismantling facility was tested. The candidate products had undergone a multi-stage hierarchical temperature regime on their macro and subassembly disassemblies and results reported. Two forms of SMA actuators were employed in the designs of actuators; these were one-way Nickel-Titanium (NiTi) and two-way Copper-Zinc-Aluminum (CuZnAl) actuators

Thomas Hobbes and the phenomena of civil war: A textual exposition of Hobbes’s commitment to the empirical and historical existence of the state of nature.

Did Thomas Hobbes consider his conception of the state of nature to be based within any empirically verifiable reality? The foundational predicates of this thesis can be reduced to two fundamental points: 1. That Hobbes’s belief in the existence in the state of nature was sincere. 2. The most pertinent empirical basis for the state of nature expressed by Hobbes was civil war, specifically, the English Civil War Period. The analytical trajectory of the thesis will endeavour, whenever possible, to pursue channels of inquiry which correspond to the two key predicates adumbrated above. The format has been styled as a “textual exposition” because the method endorsed will seek to expose Hobbes’s commitment to the existence of the state of nature from the words that he himself had written. Whether they be elements of his renowned philosophical system, or written material situated outside the terminus of his political science. Such as his correspondence, or lesser-known publications. Secondary material written about Hobbes’s state of nature, and the judgments of such authors as created them will of course be consulted at various points. However, to the primary material, containing Hobbes’s own judgments on the state of nature and its relationship with civil war, is accorded the greater responsibility for validating the premises of this thesis

Static measurement of the thickness of the ablative coating of the solid rocket boosters

The Solid Rocket Boosters (SRB's) used to launch the Space Shuttle are coated with a layer of ablative material to prevent thermal damage when they reenter the earth's atmosphere. The coating consists of a mixture of cork, glass, and resin. A new coating (Marshall Convergent Coating, MCC-2) was recently developed that is environmentally complaint. The coating must meet certain minimum thickness standards in order to protect the SRB. The coating is applied by a robot controlled nozzle that moves from the bottom to top, as the rocket part rotates on a table. Several coats are applied, building up to the desired thickness. Inspectors do a limited amount of destructive 'wet' testing. This involves an inspector inserting a rod in the wet coating and removing the rod. This results in a hole that, of course, must be patched later. The material is cured and the thickness is measured. There is no real-time feedback as the coating is being applied. Although this might seem like the best way to control thickness, the problems with 'blowback' (reflected material covering the sensor) are formidable, and have not been solved. After the thermal coating is applied, a protective top coat is applied. The SRB part is then placed in a oven and baked to harden the surface. The operations personnel then measure the thickness of the layer using the Kaman 7200 Displacement Measuring System. The probe is placed on the surface. One person (the inspector) reads the instrument, while another(the technician) records the thickness. Measurements are taken at one foot intervals. After the measurements are taken, the number of low readings is tabulated. If more than 10 percent of the points fall below the minimum value, there is a design review, and the part may be stripped of coating, and a new coating is applied. There is no other analysis
