That ice‐creams prepared with dirty materials and under dirty conditions will themselves be dirty is a proposition which, to the merely ordinary mind, appears to be sufficiently obvious without the institution of a series of elaborate and highly “scientific” experiments to attempt to prove it. But, to the mind of the bacteriological medicine‐man, it is by microbic culture alone that anything that is dirty can be scientifically proved to be so. Not long ago, it having been observed that the itinerant vendor of ice‐creams was in the habit of rinsing his glasses, and, some say, of washing himself—although this is doubtful—in a pail of water attached to his barrow, samples of the liquor contained by such pails were duly obtained, and were solemnly submitted to a well‐known bacteriologist for bacteriological examination. After the interval necessary for the carrying out of the bacterial rites required, the eminent expert's report was published, and it may be admitted that after a cautious study of the same the conclusion seems justifiable that the pail waters were dirty, although it may well be doubted that an allegation to this effect, based on the report, would have stood the test of cross‐examination. It is true that our old and valued friend the Bacillus coli communis was reported as present, but his reputation as an awful example and as a producer of evil has been so much damaged that no one but a dangerous bacteriologist would think of hanging a dog—or even an ice‐cream vendor—on the evidence afforded by his presence. A further illustration of bacteriological trop de zèle is afforded by the recent prosecutions of some vendors of ice‐cream, whose commodities were reported to contain “millions of microbes,” including, of course, the in‐evitable and ubiquitous Bacillus coli very “communis.” To institute a prosecution under the Sale of Food and Drugs Act upon the evidence yielded by a bacteriological examination of ice‐cream is a proceeding which is foredoomed, and rightly foredoomed, to failure. The only conceivable ground upon which such a prosecution could be undertaken is the allegation that the “millions of microbes ” make the ice‐cream injurious to health. Inas‐much as not one of these millions can be proved beyond the possibility of doubt to be injurious, in the present state of knowledge; and as millions of microbes exist in everything everywhere, the breakdown of such a case must be a foregone conclusion. Moreover, a glance at the Act will show that, under existing circumstances at any rate, samples cannot be submitted to public analysts for bacteriological examination—with which, in fact, the Act has nothing to do—even if such examinations yielded results upon which it would be possible to found action. In order to prevent the sale of foul and unwholesome or actual disease‐creating ice‐cream, the proper course is to control the premises where such articles are prepared; while, at the same time, the sale of such materials should also be checked by the methods employed under the Public Health Act in dealing with decomposed and polluted articles of food. In this, no doubt, the aid of the public analyst may sometimes be sought as one of the scientific advisers of the authority taking action, but not officially in his capacity as public analyst under the Adulteration Act. And in those cases in which such advice is sought it may be hoped that it will be based, as indeed it can be based, upon something more practical, tangible and certain than the nebulous results of a bacteriological test.

Partitioned analysis is an increasingly popular approach for modeling complex systems with behaviors governed by multiple, interdependent physical phenomena. Yielding accurate representations of reality from partitioned models depends on the availability of all necessary constituent models representing relevant physical phenomena. However, there are many engineering problems where one or more of the constituents may be unavailable because of lack of knowledge regarding the underlying principles governing the behavior or the inability to experimentally observe the constituent behavior in an isolated manner through separate-effect experiments. This study aims to enable partitioned analysis in such situations with an incomplete representation of the full system by inferring the behavior of the missing constituent.

This paper presents a statistical method for inverse analysis infer missing constituent physics. The feasibility of the method is demonstrated using a physics-based visco-plastic self-consistent (VPSC) model that represents the mechanics of slip and twinning behavior in 5182 aluminum alloy. However, a constituent model to carry out thermal analysis representing the dependence of hardening parameters on temperature is unavailable. Using integral-effect experimental data, the proposed approach is used to infer an empirical constituent model, which is then coupled with VPSC to obtain an experimentally augmented partitioned model representing the thermo-mechanical properties of 5182 aluminum alloy.

Results demonstrate the capability of the method to enable model predictions dependent upon relevant operational conditions. The VPSC model is coupled with the empirical constituent, and the newly enabled thermal-dependent predictions are compared with experimental data.

The method developed in this paper enables the empirical inference of a functional representation of input parameter values in lieu of a missing constituent model. Through this approach, development of partitioned models in the presence of uncertainty regarding a constituent model is made possible.

This review aims to evaluate and review literature published in the area of rising concerns that red meat consumption may be associated with risk of type 2 diabetes mellitus (T2DM), although there have been discrepancies between study findings, and put the findings into context.

Using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, a systematic literature review was undertaken to locate and summarise relevant studies which included epidemiological and clinical studies published between 2004 and 2014.

A total of 23 studies were found, with 21 epidemiological and two clinical studies meeting the criteria. Overall, the totality of the evidence indicates that while processed meat consumption appears to be associated with T2DM risk, the effect is much weaker for red meat, with some associations attenuated after controlling for body weight parameters. Where studies have considered high intakes in relation to T2DM risk, meat intake has tended to exceed 600 g per week. Therefore, keeping red meat intakes within recommended guidelines of no more than 500 g per week, while opting for lean cuts or trimming fat, would seem to be an evidence-based response.

The majority of studies conducted to date have been observational cohorts which cannot determine cause and effect. Most of these used food frequency questionnaires which are known to be subject to misclassification errors (Brown, 2006). Clearly, more randomised controlled trials are needed to establish whether red meat consumption impacts on markers of glucose control. Until then, conclusions can only be viewed as speculative.

This paper provides an up-to-date systematic review of the literature, looking at inter-relationships between red meat consumption and T2DM risk.

The purpose of this paper is to assess the effects of mindfulness training (MT) on employee well-being. Mindfulness is the awareness of one’s thoughts, emotions, sensations, actions and surroundings in the present moment.

The authors used pre-post training measures and a four-week follow-up on a sample of 23 employees from a UK-based organization. The MT group (n=12) received a weekly two-hour training over eight weeks whilst the control group (n=11) received no training. Qualitative interviews (n=36) were conducted with the MT group at three time points to further assess the subjective experiences of training participants.

Compared to the control group, the MT group significantly increased their mindfulness skills including observing and acting with awareness. Scores on well-being, i.e. satisfaction with life, hope and anxiety also improved and were generally maintained at follow-up. Some improvements were seen in the control group too but there was a larger difference in change scores in the MT group on most variables. Qualitative data show additional benefits of MT such as improved concentration at work and better interpersonal relationships. More practice at home led to greater benefits suggesting a dose-response relationship between the amount of practice and substantial benefits.

Inviting participants to have a greater amount of practice between sessions may further increase the benefits of mindfulness. Future research should consider a longer follow-up period to further explore the sustainability of the training benefits.

Employing a mixed-method approach, this study showed that MT is a viable psychological intervention for enhancing employee well-being.

This study examines key adaptations that occurred in the Zimbabwean Results-Based Financing (RBF) programme between 2010 and 2017, locating the endogenous and exogenous factors that required adaptive response and the processes from which changes were made.

The study is based on a desk review and thematic analysis of 64 policy and academic literatures supplemented with 28 multi-stakeholder interviews.

The programme experienced substantive adaption between 2010 and 2017, demonstrating a significant level of responsiveness towards increasing efficiency as well as to respond to unforeseen factors that undermined RBF mechanisms. The programme was adaptive due to its phased design, which allowed revision competencies and responsive adaptation, which provide useful insights for other low-and-middle income countries (LMICs) settings where graduated scale-up might better meet contextualised needs. However, exogenous factors were often not systematically examined or reported in RBF evaluations, demonstrating that adaptation could have been better anticipated, planned, reported and communicated, especially if RBF is to be a more effective health system reform tool.

RBF is an increasingly popular health system reform tool in LMICs. However, there are questions about how exogenous factors affect RBF performance and acknowledgement that unforeseen endogenous programme design and implementation factors also greatly affect the performance of RBF. As a result, a better understanding of how RBF operates and adapts to programme level (endogenous) and exogenous (external) factors in LMICs is necessary.
