Abstract
Purpose
Current single head pick and place robots have reached their practical limit for throughput rates due to impractical speeds and acceleration, which often damage or lose the product being transferred. The purpose of this paper is to present a new system which uses 2 XY motion slides and an indexing flexible conveyor to achieve a more desired motion while achieving a high throughput rate.
Design/methodology/approach
An innovative robotic pick and place motion design (the FlowBot) was previously created to address the changing needs of the packaging and automation industry. A full patent has been filed covering this technology. This paper documents a refinement to the FlowBot concept that produces a more compact implementation, entitled the Compact FlowBot.
Findings
Tit was found that the motion of smaller steps with limited accelerations does produce higher throughputs without the excessive accelerations that Delta robots produce. The robotics system does require limited Z height so the potential for multiple stacked systems is presented.
Originality/value
This novel robot has been found to be a next generation design, which has been confirmed by an international patent search. Many established consumer packaging goods companies and food processing companies have lauded its merits. The system needs to move into prototype and full development mode.

Abstract
Purpose
The purpose of this paper is to examine relevant case law governing the failure and/or success of global or rolled‐up claims, where it is said to be impractical or impossible to demonstrate the links between certain causes of action and the monetary value to be attached to each. The paper proposes a theoretical framework to improve a claimant's prospects of success in advancing a global claim, not only in circumstances where it may be impractical or impossible to provide a breakdown but also where a cost benefit analysis concludes it is reasonable to do so.
Design/methodology/approach
The paper uses traditional doctrinal legal methodology to evaluate judicial statements on the merits of global claims from a number of jurisdictions. The paper also draws on key authorities from the realms of health and safety and professional negligence.
Findings
The cases demonstrate attempts by the court to recognise the problems faced by claimants at the end of a construction contract where their total costs exceed the agreed contract price. The comparative success or failure of a global claim depends on the judicial approach to a number of factors including: impossibility, impracticability, conduct of the claimant and defendant, balance between excessive particularity and basic information, the keeping of records, the costs of claim preparation and apportionment. There remains a significant risk of failure of a global claim but the risk can be reduced significantly provided the claimant conducts a defensible cost benefit analysis of the approach taken.
Practical implications
A global claim can be used more often provided the rationale behind its presentation forms a logical basis. The cost of litigating complex construction contracts can be reduced significantly if global claims can become the norm rather than the exception, provided the claimant conducts a cost benefit analysis and the court concludes the analysis is reasonable and defensible.
Originality/value
Traditional legal theory relies upon the proposition that the claimant must prove that to which he believes he is entitled to such an extent that the defendant's right to know the case it has to meet is satisfied. This paper adds value to the theory by proposing a radical strategy whereby a reasonable claimant can assist the court in finding a factual and logical basis for awarding the whole of a global claim and, where appropriate, by deduction in addition to the principle of apportionment, less than the whole.

Abstract
A “ Practitioner of over Forty Years' Experience ” in a letter to the Pall Mall Gazette observes that few members of the medical profession “ regard ‘ calories ’ and such like as guides to treatment of patients, simply because they cannot implicitly rely upon laboratory experiments. Anyhow, they do not impress the profession generally, as their doubts are based upon everyday experiences.” The real point that seems to have been overlooked by the so‐called experts is that, “ although the same amount of nourishment may be present in two substances, according to laboratory experiments, it does not necessarily follow we can assimilate them equally well. Here is a case in point. We know that starch and dextrine are similar, and contain very nearly the same amount of nourishment, and, chemically, are almost indistinguishable; hence biscuits should be as supporting as bread. But it is a known fact that soldiers cannot march and thrive so well on the former as upon the latter (notwithstanding that in the point of nourishment as shown by laboratory experiments, 18 ounces of biscuit are said to equal 24 ounces of freshly made bread), hence it comes about that ovens are sent to the front rather than tons of biscuits. It is not meant that biscuits are not nourishing, but merely that they cannot be assimilated so well as bread, dextrine so well as starch.”

Abstract
This chapter, inspired by the authors’ experiences with racism and sexism in higher education leadership and frontier Protestantism, will interrogate the leadership models found in library and information science (LIS) through the lens of Judeo-Christian religious social structures and terminology, along with an examination of transitional and transformational leadership frameworks, to suggest a more productive and less abusive leadership model, equitable and inclusive to those who are not white men.

Abstract
The recent publication of Cysticercosis—an Analysis and Follow‐up of 450 Cases, by Drs. Dixon and Lipscombe (M.R.C. Special Report, Series No. 299) which is believed to contain information relating to all human infestations with C. Cellulosœ in this country up to 1957, prompts one to look at another picture of cysticercosis, viz., C. bovis in cattle. Almost all the cases of human cysticercosis followed up in the report were among British service personnel who had served in India and other eastern sectors, but chiefly India. Since no British troops have served in this area for the past 13 years, human cysticercosis, always a rare disease, is becoming even rarer.

Abstract
The unsatisfactory state of the law with regard to prosecutions for impoverished milk has been further exemplified in a series of prosecutions at Oldham. Three farmers were summoned for having sold milk “ not of the nature, substance and quality demanded by the purchaser,” and the evidence produced showed that the milk in each case was not only deficient as compared with the standard set by the Board of Agriculture, but even more deficient when compared with mixed samples taken at the farm. The Deputy Town Clerk, who conducted the prosecution, pointed out that the case of Wilkinson v. Clark clearly showed that the Inspectors were justified in going to the farm for a second sample, if the second was comparable with the first, and were entitled to rely on the Public Analyst's certificate for both samples. He argued that, in view of the enhanced price of milk, it was very necessary that the purchaser should be adequately protected and that he should obtain what he paid for — pure unadulterated milk. The defence in the first case was a denial of the milk having been tampered with, it being sold “ as it came from the cow.” Results of experiments at the Yorkshire College for Agricultural Education were quoted to show that wide variations in the quality of the milk might occur for which the farmer ought not to be held responsible. In the present case it was admitted that one of the cows was not milking satisfactorily, and had a “ hard udder.” The milk from this cow when examined closely, was stated in the defendant's evidence to be “ more like water.” This had only been found out on the morning when the first sample had gone into the churn for sale. The Bench, after consultation, expressed themselves satisfied that the milk had not been tampered with, and dismissed the summons.

Abstract
Retaining students is a critical topic in higher education. A plethora of research has investigated demographic, age, life stage, ethnicity, and a host of other variables that influence retention. Colleges have responded to retention issues with a host of classes, workshops, and orientation or mentoring programs to aid student retention. Specifically, this study compares the retention concerns of high school students considering college vs the concerns of existing college students in a variety of degree programs to see if factors vary over time. Using a case study approach, the study found three key variables associated with retention problems. The discussion and conclusions identify ways for colleges to alter both marketing and assistance programs for both groups. Suggestions for replication and areas for future research as well as implications for policy directions are included.
