Abstract
Purpose
The purpose of this paper is to examine the impact of supplement form and dosage level on consumers’ perceptions of dietary supplement efficacy.
Design/methodology/approach
The authors draw upon literature on dietary supplements and accessibility–diagnosticity theory to derive their hypotheses. Hypotheses are tested through two experiments that use a 2 (supplement form: single-ingredient [SI] vs multi-ingredient [MI]) × 2 (dosage level: low vs high) factorial design.
Findings
The findings show that consumers perceive that lower dose MI supplements are more effective than lower dose SI supplements, consistent with a “more is better” heuristic. In contrast, under high doses, the supplement form effect is insignificant; that is, MI and SI supplements are perceived to be comparable in terms of efficacy.
Practical implications
Dietary supplements are not regulated the same way as prescription drugs. Consumers often draw inferences about supplement efficacy based on their perceptions rather than objective evidence. This may leave consumers vulnerable to potentially harmful consequences. This research has implications for designing supplement marketing efforts and public policy, which could help consumers to make informed choices when purchasing dietary supplements.
Originality/value
A growing awareness of the importance of maintaining a healthy lifestyle has motivated consumers of all ages to consider alternative remedies, most notably using dietary supplements. Past research offers little insight into understanding consumer reactions to dietary supplement form such as SI and MI supplements and their dosage levels. The studies reported here address this gap in research. Public policy and marketing implications are also discussed.

Abstract
Purpose
The dynamic landscape of healthcare has seen significant changes in marketing by the various types of healthcare providers. This research aims to explore the impact of emotions in healthcare advertising.
Design/methodology/approach
Two consumer panel experiments investigate the role of hope and empathy appeals in fostering positive evaluations toward healthcare providers (medical centers for serious illnesses).
Findings
Study 1 shows that two types of emotion-based healthcare appeals are more effective than non-emotional appeals. Study 2 compares the relative effectiveness of hope versus empathy appeals with medical expert or typical person (patient) testimonials.
Research limitations/implications
Findings demonstrate that in a healthcare context, an expert testimonial enhanced the persuasiveness of a hope-based appeal, whereas testimonials from unknown patients were not effective.
Originality/value
Understanding the role of emotions in healthcare advertising is increasingly important as healthcare providers compete on care and quality outcomes and advertising agencies vie for the attention of consumers.

Abstract
IN last month's Library World attention is drawn to the subject of literary history and its teaching by Mr. Sayers, who points out some weak points in the syllabus and examination scheme of the Library Association. His remarks recall the fact that this subject has always been a difficult and rather inflammable one to tackle, because wrapped up in it is that other exciting question of Language, which must be taken in connection with Literature when considered as a teaching subject. We understand that the Literary History syllabus of the L.A. is merely a compromise, which arose out of a tangle caused by the language difficulty. The draft scheme for the teaching of Literary History which was first submitted, provided for a very strict limitation of the subject to the great authors of all nations, according to a list which had been prepared. This scheme proposed to get over the language difficulty by allowing for all purposes the use of text‐books and translations in English, because it was felt to be utterly ridiculous to expect students to be equipped with first‐hand knowledge of Homer, Dante, Hafiz, Confucius, the Vedas, Moliére, Cervantes, Schiller, Virgil, Tolstoy, and other great authors. This proposal, which would have limited the requirements of the examination to a biographical and critical knowledge of about 300 or 400 of the greatest authors of all times, was rejected, and in its place was adopted the compromise to which Mr. Sayers and many others object. This compromise on the face of it, limits the examination to English Literature only, but, when more closely scanned, it will be found also to demand a most extraordinary knowledge of all kinds of foreign authors, in a form which has not yet been systematically recorded. Apart from this, the dimensions of an unlimited survey of English Literature are enormous, because there is no attempt at definition. All that can be gathered from the actual Examination Papers is that the examiners have largely confined themselves to the purely critical side of the subject. But students are not told that modern technical and scientific literature is excluded, nor is any indication given which will show that it is the “literature of power,” and not of “knowledge,” in which candidates are expected to be proficient. Now, it is perfectly well known to every reader that not 1 per cent. of the books published is literature at all. The output of printed matter all over the world consists mostly of Lamb's “books which are not books”—text‐books, ephemera, rubbish in general, and other nondescript essays in typographical art—which have no real place in a Literary History Syllabus. It was to get over this anomaly, and equip students with the knowledge mostly required in libraries—an acquaintance with “books which are not books”—that the original draft scheme for the Literary History syllabus imposed a limitation which should prove effective in confining the examination to pure literature, and relegating the literature of knowledge to the sections devoted to Bibliography and Book Selection. In the present Syllabus, as revised, this distribution actually takes place, but with an extraordinary degree of overlapping which makes it necessary for a candidate to pass thrice in Literary History! He must first pass in Section I. Literary History, which demands among many other things a “knowledge of the editions and forms in which the works of the authors have been published.” Good. No limitation here, and any examiner would, accordingly, be perfectly fair and within his rights in asking for bibliographical details of Cocker's Arithmetic or Buchan's Domestic Medicine. Again, in Section II., Elements of Practical Bibliography, we have a demand for knowledge of book selection, the best books and periodicals, and courses of reading. Here, once more, no limitation, and again an examiner could ask when the first edition in English of the “Arabian Nights” was published,or what is the best edition of Cædmon or the Koran. Finally, in Section V., Library History and Organization, the same requirements are set forth, without any limitation, and candidates are evidently expected to possess a full knowledge of all literature before they can obtain a certificate. All this is very confusing and absurd, and gives point to every complaint which has been uttered against this part of the scheme of examinations. After all, a dilletante, gossipy, pseudo‐critical acquaintance with literary history is of very‐little practical value, compared with exact bibliographical knowledge concerning great authors and their works. For this reason we think the Association should carefully revise its Syllabus, and adopt a better‐proportioned and more equitable distribution of the subject. Section I. certainly requires strict limitation within reasonable bounds, and it ought to be confined to a working knowledge of the chief authors of the world according to a carefully prepared list of names. This should demand knowledge of biographical and critical facts, plus enough of bibliographical detail regarding titles to satisfy an examiner. Failing this, a list of authors, periods, or subjects selected for study and examination should be issued every year before the examination; but a fixed limitation to begin with would, we think, be better.

Abstract
DURING much of the Second World War, the affairs of the Library Association were conducted for the Council by an Emergency Committee. The record of its meeting on 10th June 1941, includes the following: “A resolution having been received suggesting that a committee be formed to consider post‐war reconstruction, it was resolved that by means of a notice in the LIBRARY ASSOCIATION RECORD, Branches and Sections should be invited to formulate suggestions for the consideration of the committee. A draft questionnaire for the purpose of an enquiry into the effects of the war on the public library service was approved”. In July, the Committee reported “further arrangements … for carrying out an exhaustive survey designed to give the necessary data for full and detailed consideration and ultimate recommendation as to the future of public libraries, their administration and their place in the social services”. The promised notice appeared as an editorial in September.

Abstract
In this chapter, I want to take some stock of the subdiscipline of environmental sociology. I believe that a productive approach to restoring some of the coherence of environmental sociology is to conceive of mainstream environmental sociology as reflecting several paradoxes. The bulk of this chapter will be devoted to a brief explication of environmental sociology's theoretical and empirical paradoxes. I will begin with three paradoxes that have played a major role in environmental sociology since the 1970s. However, many of the theoretical and empirical paradoxes of the subfield are relatively new ones – and some have not even been thought of as paradoxes. The thrust of the present chapter consists of something of a research agenda for environmental sociology for the next decade or so.
