Abstract

Purpose

Dahlia is an ornamental plant originating from Mexico where it is considered as the National flower. The purpose of this paper is to investigate tubers from yellow, white and red‐flowered cultivars of the common garden Dahlia (D. pinnata) for their chemical composition.

Design/methodology/approach

The composition of minerals was determined using Atomic Absorption Spectrometry (AAS), whereas vitamins were analyzed by High‐Performance Liquid Chromatography (HPLC).

Findings

Carbohydrates represented the major constituent in Dahlia tubers, followed by fibre and protein. Tubers of the yellow‐flowered cultivar “HGH” contained the highest amount of carbohydrates, while tubers of the white‐flowered cultivar “BJ” and those of the red‐flowered cultivar “XM” abounded in fibre and protein, respectively. In addition, Dahlia tubers exhibited varying concentrations of minerals, among which potassium, calcium, magnesium, phosphorus, zinc and chromium were predominant. Tubers of the white‐flowered cultivar “LB” contained the highest amounts of magnesium and phosphorus. Moreover, tubers of the red‐flowered cultivar “MLH” showed the highest contents of potassium and chromium, whereas those of the red‐flowered cultivar “XM” were rich in calcium and zinc. Furthermore, Dahlia tubers were found to contain water and fat soluble vitamins, among which vitamins B2, B6, B7 and E were the most abundant. Tubers of the white‐flowered cultivar “BJ” exhibited the highest contents of water soluble vitamins, whereas those of the white‐flowered cultivar “LB” abounded in fat soluble vitamins.

Originality/value

Despite the considerable variability observed among cultivars, Dahlia might be utilized as an alternative food resource for human nutrition.

Abstract

In a world in which “England's green and pleasant land” sets the standard for garden excellence, gardeners in much of the United States will struggle in vain to adapt the British style to their own volatile climates. American regional gardening literature offers a new vision to help gardeners throughout the United States select plants suited to their climates (especially native plants) and use techniques to prevent losses to cold, heat, humidity, or drought. The resulting gardens may not always resemble the traditional English her baceous border, but their beauty and vigor will enhance the often monotonous American suburban landscape.

Abstract

Purpose

Participation in urban horticulture (UH) is increasing in popularity, and evidence is emerging about the wide range of social and environmental benefits “grow your own” can also provide. UH can increase mental and physical well-being, as well as improve nature connectedness, social capital and community cohesion.

Design/methodology/approach

This study focusses on allotments, which is one of the dominant forms of UH that takes place in the United Kingdom. 163 volunteers in England and Wales participated in keeping a year-long allotment diary as part of a citizen science project investigating activities on allotment gardens. This study examines the unprompted comments that 96 of these gardeners offered as observations when visiting their allotment plots.

Findings

Participants recorded high levels of social and community activities including the sharing of surplus food produce, knowledge exchange, awareness and interaction with wildlife, emotional connection to their allotment, appreciation of time spent outside and aesthetic delight in the natural world around them.

Originality/value

At a time when waiting lists for allotment plots in the United Kingdom are on the rise, and allotment land is subject to multiple pressures from other forms of development, this study demonstrates that these spaces are important sites not only for food production but also health, social capital and environmental engagement.

Abstract

AT the close of the year it seems to be an impossible task to indicate the many‐phased activities it has shown in librarianship. There is the overall proof that despite all competitors the reading of books continues to increase. Statistics, for what they are worth—we believe them to be in the main quite honest and unmanipulated—are available for public libraries, town and county, only. The lending libraries of these put out nearly 385 million volumes, a figure difficult to grasp. That, however, is only one part, if the largest, of the reading of our people: commercial, technical, university, collegiate, learned society and school libraries play an enormous part in the reading of our people; and what the individual reader buys in the way of books the returns of booksellers might show but, even here, there are so many overlappings that any figures would be incomplete. Statistics which have no clear method and are subject to varying interpretations are valueless. What we do know is that we are a reading nation and there is the accompanying mystery that so many men and women seem never to have read a worth‐while book.

Abstract

MIDSUMMER sees the general settling down of thoughtful librarians to a contemplation of their Winter programmes. This seems a cruel suggestion since (if we are fortunate) the skies are still blue above us, the trees green, and—well, holidays are just ahead. One duty, however, belongs to midsummer and that is the annual election of the Library Association Council. There is growing evidence that in this matter we are no longer prepared to leave our representation in the most important council that exists for us to chance. By the time these words appear the question, so far as 1928 is concerned, will have been settled. We hope a well‐balanced Council will be the result, and that, after an interval of several years, Ireland will be represented.

Abstract

Here is the long‐awaited fourth edition of Ralph De Sola's classic Abbreviations Dictionary. This updated edition of a work first published in 1958 is the largest, most complete compilation of its kind — a reference book far surpassing all others in the field. Mr. De Sola has expanded his work to include more than 130,000 definitions and entries — over 77,000 definitions, over 54,000 entries. The current edition offers abbreviations, acronyms, anonyms, contradictions, initials and nicknames, short forms and slang shortcuts, and signs and symbols covering disciplines which range from the arts to the advanced sciences and embrace all areas of human knowledge and activity.

Abstract

BUSINESS SCHOOL GRAFFITI is a highly personal and revealing account of the first ten years (1965–1975) at Britain’s University Business Schools. The progress achieved is documented in a whimsical fashion that makes it highly readable. Gordon Wills has been on the inside throughout the decade and has played a leading role in two of the major Schools. Rather than presuming to present anything as pompous as a complete history of what has happened, he recalls his reactions to problems, issues and events as they confronted him and his colleagues. Lord Franks lit a fuse which set a score of Universities and even more Polytechnics alight. There was to be a bold attempt to produce the management talent that the pundits of the mid‐sixties so clearly felt was needed. Buildings, books, teachers who could teach it all, and students to listen and learn were all required for the boom to happen. The decade saw great progress, but also a rapid decline in the relevancy ethic. It saw a rapid withering of interest by many businessmen more accustomed to and certainly desirous of quick results. University Vice Chancellors, theologians and engineers all had to learn to live with the new and often wealthier if less scholarly faculty members who arrived on campus. The Research Councils had to decide how much cake to allow the Business Schools to eat. Most importantly, the author describes the process of search he went through as an individual in evolving a definition of his own subject and how it can best be forwarded in a University environment. It was a process that carried him from Technical College student in Slough to a position as one of the authorities on his subject today.

Abstract

WHILE there is no doubt that the system of issuing books at “net” prices is of great benefit to booksellers, there is also no doubt that, unless care is taken, it is a serious drain upon a limited book‐purchasing income. A few years ago the position had become so serious that conferences were held with a view to securing the exemption of Public Libraries from the “net” price. The attempt, as was perhaps to be expected, failed. Since that time, the system has been growing until, at the present time, practically every non‐fictional book worth buying is issued at a “net price.”
