Dyadic leadership models, in which two professionals jointly lead and share unit responsibilities, exemplifies a recent trend in health care. Nonetheless, much remains unknown about their benefits and drawbacks. In order to understand their potential impact, we conducted a review of literature evaluating dyad leadership models in health systems.

Our narrative review began with a search of PubMed, CINAHL, Web of Science and Scopus using key terms related to dyads and leadership. The search yielded 307 articles. We screened titles/abstracts according to these criteria: (1) focus on dyadic leadership model, i.e. physician–nurse or clinician–administrator, (2) set in health care environment and (3) peer-reviewed with an evaluative component of dyadic model. This yielded 22 articles for full evaluation, of which six were relevant for this review.

These six articles contribute an assessment of (1) teamwork and communication perceptions and their changes through dyad implementation, (2) dyad model functionality within the health system, (3) lessons learned from dyad model implementation and (4) dyad model adoption and model fidelity.

Research in this area remains nascent, and most articles focused on implementation over evaluation. It is possible that some articles were excluded due to our methodology, which excluded nonEnglish articles.

Findings provide guidance for health care organizations seeking to implement dyadic leadership models. Rigorous studies are needed to establish the impact of dyadic leadership models on quality and patient outcomes.

This review consolidates evidence surrounding the implementation and evaluation of a leadership model gaining prominence in health care.

Dorothy Hollingsworth opened the session by inviting the four panel members to give a short talk on their own personal view on the status of food today.

Nutrition is a serious and immensely important scientific discipline researched and taught in universities worldwide. Its relevance to everyday life makes it unique among the sciences. It is written about not only in the scientific literature but also in the popular media. It is talked about on television and the radio in a way more befitting the fashion clothes industry than a science, often by people no more qualified to do so than anyone else. It is also at the root of the world′s largest industry, the agro‐food industry, and consequently attracts enormous interest from another almost equally as large – the advertising and public relations industry – as well as from politicians. Poses the questions: what has shaped our current attitudes to human nutrition and what are our sources of information about it?

The debate about the relationship between sugar consumption and aberrant behaviour is far from new and has no more solid scientific basis now than it did forty years ago. Yet it might be thought, on the basis of the number of articles published in the lay press and non‐mainstream medical and scientific press that a mass of new information was available incriminating the sugars, glucose, sucrose, or both.

The total amount of glucose in the body at any one time is very small indeed, rarely exceeding 20g in total and generally less than half that amount. This would ordinarily be sufficient to keep the brain and red cells, the only major glucose‐requiring tissues, supplied with energy for a little more than an hour or so were it not constantly being replenished either by food or, in the interval between meals, by glycogen stores in the liver. Even these stores contain sufficient carbohydrate to meet requirements for only 24 hours or so yet we know from experimental and clinical evidence that most people can survive, providing they have ready access to water, for days or even weeks without food and without their blood glucose level falling to below 75% of their ordinary overnight fasting level. This is because under conditions of dietary carbohydrate deprivation the body has the capacity, by means of a series of interrelated mechanisms, to reduce, to an absolute minimum, the utilisation of glucose as a fuel by all the tissues of the body save the brain and red cells and at the same time increase glucose production in the liver. In between meals and during longer fasts, fat becomes the major fuel of all the tissues of the body apart from the brain and red cells.

In the very able and striking address which he recently delivered before the Society of Arts, Sir WILLIAM PREECE insisted that commercial success—whether of a man, of a body of men, or of a nation—is referable to the working of distinct laws, the recognition and study of which may justly be said to constitute a “science of business.” In terms rendered the more severe by their dispassionate and moderate character, Sir WILLIAM referred to the lamentable ignorance displayed by the legislature, by the manufacturer, and by the general public, of what may bo regarded as the most elementary facts and methods upon which such a science must be based. He pointed to the loose and bungling character of our commercial legislation; to the lack of co‐operation and combination; to the nonexistence of a properly organised and effective consular service whereby full information could be supplied and the interests of British trade, both home and colonial, might be studied and advanced; and finally to the lethargy of British producers and manufacturers themselves, who allow foreign competitors to drive them out of even their own home markets without making an effort to discard the old‐fashioned and worn‐out methods which have given those competitors the advantage. Of late years the warning voice has been raised from time to time, but it has been as a voice crying in the wilderness. The remarkable speech delivered at the Guildhall by H.R.H. THE PRINCE OF WALES is fresh in the recollection of those who are not too drowsy or too indifferent to appreciate the vital nature and the magnitude of the evil. In 1891 Lord PLAYFAIR stated that if the Americans were right in principle in the management of some of their commercial concerns, “the whole policy of the United Kingdom was founded on a gigantic error, and must lead to our ruin as a commercial nation.” Sir WILLIAM PREECE is amply justified in attaching severe blame to the British manufacturer and producer. They have allowed “the Americans and the Germans to oust them out of their own markets, not by any superiority in the quality of their goods, but by lower prices, by superior knowledge of the demands of the markets, by the establishment of new markets, by better direct communication with foreign countries, by superior methods in business ways, by establishing regular intelligence departments, and, above all, by possessing and exercising superior commercial technical knowledge,” “and,” continued Sir.WILLIAM, “they must lay aside the commercial habits of their fathers.” With regard to food‐products, for instance, can it be truly said that any adequate steps are taken to secure any satisfactory and permanent improvement of the national food supply with respect to purity and good quality? Has anything been done, with governmental or legislative assistance, to make a systematic study of, and provide authoritative information upon such questions as the sources from which food stuffs are obtained, the adequacy or inadequacy of supplies, the true value of home‐produce and the advantages of utilising colonial products as far as possible? The answers to these questions can only be emphatically in the negative. There is no civilised country in the world in which the producer and vendor of adulterated, impoverished, and inferior articles of food can cany on their nefarious practices with more impunity, in certain respects, than in the United Kingdom, although, originally, we led the way in framing legislative enactments on these all‐important matters. At every port of entry today we might most appropriately set up the old waste‐land notice that “rubbish may be shot here.” As we offer all the necessary facilities, and as they are being taken advantage of more and more, wo might also freely advise that “rubbish should bo manufactured here” as well, What steps do British producers and manufacturers of articles of food take to move with the times, to set their houses in order, to protect themselves, and to enable the public to differentiate between the good and the bad? In the vast majority of instances the attitude they adopt is still one of unmasterly inactivity, except in the direction of unscientific and clumsy advertisement. On this they spend enormous sums without proportionate returns, and in following this course they constantly lay themselves open to condemnatory criticism by the publication of unauthorised and exaggerated statements which, in spit© of CARLYLE'S dictum “mostly fools,” are now merely received by the general public with a shrug of the shoulders. The time has come when, in order not only to develop their trade but in order to keep it, British manufacturers must give evidence of an independent and authoritative character to justify the faith that is presumably in them in recommending their goods to the public. Those who refuse to entertain new ideas and who are content to rest in a semi‐comatose condition on the achievements of the past,—relying merely on the possession of the hitherto reputable “name of the firm,”—by the operation of an inexorable law must inevitably drop out of the race.

This study aimed to document the life experiences of child miners (CMs) engaged in small-scale gold mining system (SSGMS) in Paracale using qualitative and ethnographic approaches. Findings revealed that the SSGMS started even before the Spaniards came in 1572. Pagbibitâ (underground mining), and pagkocompressor (underwater mining) were identified as types of SSGMS (pagkakabod) with common organizational structure and CMs. Their differences were in the nature of work, roles, costs, income, equipment, and processes. Majority of the CMs are males, out-of-school youth, eldest children, and have worked from two months to nine years. Altruistic factors, a source of inspiración, motivated them to engage on mining. They view their families as poor, and mining as their primary means of livelihood and family tradición. Their life threatening or work-related risks and impoverished living conditions unquestionably infringe their children’s rights. Their aspiración include having permanent employment, better family life and community, finishing their studies, and sending their siblings to school. Perseverance and hard work are their means to realize them.

Their experiences of labour explotación and destitution are indeed social issues. Espousing social development and community organizing frameworks, good governance, holistic alternative livelihood and learning system may minimize their plight as child miners.

The National Association for Health, founded in 1960, acts as an independent advisory body on matters affecting public health, especially with regard to food. In May 1978, its members held a symposium to debate whether it was possible, desirable and practicable for dietary goals to be formulated for the UK, in view of present day eating habits and nutritional requirements.

This paper presents the results of a study comparing the ability of neural network models and multiple discriminant analysis (MDA) models to predict bond rating changes and to exam if segmentation by investment grade improves classification. Data was collected on more than 900 bonds that had their Standard and Poor's Corporation rating changed during the period 1997 to 2002. This was matched this dataset with corresponding firms which had the same initial bond rating but which did not change. The correspondence was based on the firms being in the same industry, having the same rating at the time of the change (the time frame was one month) and the same approximate asset size (within 20%). This relatively stringent set of criteria reduced the data set to 282 pairs of companies. A neural network model and a multiple discriminant analysis were used to predict both a bond change and the general direction of a movement from a particular bond rating to another bond rating. The predictive variables were financial ratios and rates of change for these ratios. In almost all cases, particularly for the larger sample studies, the neural network models were better predictors than the multiple discriminant models. The paper reviews, in detail, performance of the respective models, strengths and limitations of the models – particularly with respect to underlying assumptions- and future research directions.
