A Health Exhibition lias been lield at tlie Drill Hall, Leeds, and lias attracted mucli attention. The Public Health Department was especially instructive and included a model hygienic shop counter, fly-proof and ice-cooled, the model cow shed, a smoke-recording apparatus, a demonstration of food values, and a dozen other features conveying lessons to the eye at once. Personal cleanliness, as a...

The biofilm mode of growth can lead to diversification of the bacterial population by promoting the emergence of variants. Here we report the identification and characterization of two major subpopulations of morphological variants arising in biofilms of S. aureus. One of these lacked pigmentation (termed white variants; WVs), whilst the other formed colonies on agar that were larger and paler ...

Discovering whether social capital endowments in modern societies have been subjected or not to a process of gradual erosion is one of the most debated topics in recent economic literature. This new stream of research has been inaugurated by Putnam’s pioneering studies about social capital trends in the United States. Recently, a considerable work by Stevenson and Wolfers (2008) put a new empha...

The existing prescribed performance control (PPC) strategies exhibit the fragility and nonguarantee of when they are applied to dynamic systems with actuator saturation, moreover, all them unable quantitatively design performance. This article aims at remedying those deficiencies by proposing a new nonfragile PPC method for waverider vehicles (WVs) such that quantitative can be guaranteed track...

This study considers the job scheduling problem of minimizing the Weighted Waiting Time Variance (WWTV) of jobs. It is an extension of WTV minimization problems in which we schedule a batch of n jobs, for servicing on a single resource, in such a way that the variance of their waiting times is minimized. WWTV minimization finds its applications for job scheduling in manufacturing systems with e...

OBJECTIVE Factors that contribute to wealth related inequalities in self-rated health (SRH) and happiness remains unclear most especially in sub-Saharan countries (SSA). This study aims to explore and compare socioeconomic differentials in SRH and happiness in five SSA countries. METHODS Using the 2010/2014 World Values Survey (WVS), we obtained a sample of 9,869 participants of age 16 and ab...

In the last decades value research has produced a vast number of theoretical concepts. However, it is unclear how the different value theories relate to each other. This study makes a first step toward a systematic comparison of value theories. It focuses on the individual level of the two approaches that are, at present, probably the most prominent in international research - the theory of bas...
