Diketopyrrolopyrrole (DPP) is a critically important building block that has gained importance in the organic electronics community because of its wide applicability in various devices. In this work, the thiophene flanked DPP moiety attached to alkyl chains of various lengths (this includes straight octyl and branched ethyl hexyl units) has been used as the monomer for electropolymerization. This paper focuses on the study of optical, thermal, solid state ordering and electrochemical properties of these electron deficient monomers using various characterization techniques such as UV–Vis spectrometry (UV), photo-luminescence spectroscopy (PL), differential scanning calorimetry (DSC), thermal gravimetric analysis (TGA), X-ray diffraction (XRD), cyclic voltammetry (CV), as well as ab initio modeling. These monomers exhibit broad absorption spectra from the ultraviolet (280–400 nm) to visible (400–600 nm) regions and emission spectra between 560 and 610 nm. The band gaps of these monomers were calculated to be in the range of 2.00–2.20 eV. These monomers were electropolymerized by scanning the potential between −0.5 and 2.0 V versus ferrocene for up to 50 cycles on a glassy carbon electrode.

Navigators help rural older adults with advanced illness and their families connect to needed resources, information, and people to improve their quality of life. This article describes the process used to engage experts – in rural aging, rural palliative care, and navigation – as well as rural community stakeholders to develop a conceptual definition of navigation and delineate navigation competencies for the care of this population. A discussion paper on the important considerations for navigation in this population was developed followed by a four-phased Delphi process with 30 expert panel members. Study results culminated in five general navigation competencies for health care providers caring for older rural persons and their families at end of life: provide patient/family screening; advocate for the patient/family; facilitate community connections; coordinate access to services and resources; and promote active engagement. Specific competencies were also developed. These competencies provide the foundation for research and curriculum development in navigation.

A new method of data analysis offers a potentially powerful tool for statistically evaluating hypotheses of rate in temporally-ordered evolutionary phenomena. We present a method for bootstrapping time-ordered data sets to test hypotheses of the equality of rate. This method is applicable to both nonrandom and random generative processes. The method is applied to the data of Malmgren et al. (1983) for the Globorotalia plesiotumida–G. tumida planktonic foraminiferan lineage and the data of Reyment (1982) for the benthonic foraminiferan Afrobolivina afar. G. plesiotumida is recognizable on the basis of independent data as a species distinct from G. tumida, its descendant. Evolutionary change rate during the evolution of G. tumida from G. plesiotumida is shown to be faster than rates within either species. The pattern of variation exhibited by A. afar includes a time interval of more rapid change; this more rapid change is observed post hoc. A bootstrapping model based on post hoc observations reveals the rate in this time interval to be not significantly faster than expected in such post hoc intervals.

The overarching aim of biomimetic approaches to materials synthesis is to mimic simultaneously the structure and function of a natural material, in such a way that these functional properties can be systematically tailored and optimized. In the case of synthetic spider silk fibers, to date functionalities have largely focused on mechanical properties. A rapidly expanding body of literature documents this work, building on the emerging knowledge of structure–function relationships in native spider silks, and the spinning processes used to create them. Here, we describe some of the benchmark achievements reported until now, with a focus on the last five years. Progress in protein synthesis, notably the expression on full-size spidroins, has driven substantial improvements in synthetic spider silk performance. Spinning technology, however, lags behind and is a major limiting factor in biomimetic production. We also discuss applications for synthetic silk that primarily capitalize on its nonmechanical attributes, and that exploit the remarkable range of structures that can be formed from a synthetic silk feedstock.

Background.
Although hospital-acquired infections appear to be a growing threat to the survival of newborns in the developing world, the epidemiology of this problem remains poorly characterized.
Methods.During a 10-month period, we conducted prospective longitudinal surveillance for colonization and bloodstream infection caused by gram-negative rods among all infants hospitalized in the 2 largest neonatal intensive care units in Manila, the Philippines. We determined antibiotic susceptibilities and calculated adjusted odds ratios for risk factors for bacteremia by means of multivariate logistic regression.
Results.Of 1,831 neonates enrolled during a 10-month period, 1,017 (55.5%) became newly colonized and 358 (19.6%) became bacteremic with a drug-resistant gram-negative rod, most commonly Klebsiella species, Enterobacter species, Acinetobacter species, and Pseudomonas aeruginosa. Of the invasive isolates, 20% were resistant to imipenem, 41% to trimethoprim-sulfamethoxazole, 52% to amikacin, 63% to ampicillin-sulbactam, 67% to ceftazidime, and 80% to tobramycin. The factors significantly associated with an increased risk of bacteremia were mechanical ventilation and prematurity. Additionally, colonization with a drug-resistant gram-negative rod was an independent risk factor for bacteremia (odds ratio, 1.4 [95% confidence interval, 1.0-1.9]).
Conclusions.Colonization with a drug-resistant gram-negative rod was an independent risk factor for sepsis. If our data are typical, the unusually high intensity of colonization pressure and disease caused by multidrug-resistant gram-negative rods at these 2 neonatal intensive care units indicates an emerging healthcare crisis in the developing world. Improved infection control methods are therefore critically needed in developing countries.

While important research on the history of scientific commemorations has been published in recent years, relatively little attention has been paid to the commemoration of invention and inventors. A comparison of the centenaries of James Watt's death in 1919 and of Michael Faraday's discovery of electromagnetic induction in 1931 reveals how the image of the inventor was being refashioned in the early twentieth century. Although shortly after his death Watt had been acclaimed by the Royal Society as a great ‘natural philosopher’, a century later his reputation had been appropriated by the engineering professions and trades. As the title of Dickinson's 1935 biography described him, he was seen primarily as a ‘craftsman and engineer’, not a scientist. With poor publicity, which failed in particular to make any connection between steam power and electricity, the 1919 centenary excited little interest outside engineering circles. Meanwhile, professional scientists, who were seeking financial recognition for the importance of their research in ‘pure’ science, had found a new icon in Michael Faraday. They seized the occasion of the 1931 centenary to reinforce the link between Faraday's scientific research and the wonders of modern electrical technology and thereby to elevate the role of ‘blue-sky’ research over its ‘mere’ application.

Summary
abstract. In order to regulate risk-taking efficiently, tort liability rules governing organizations' liability for torts by their agents must ensure that organizations both want their agents to take cost-effective precautions and benefit from using all cost-effective mechanisms to regulate agents. This chapter shows that vicarious liability, the current the rule governing organizations' liability for their agents' torts, does not satisfy these objectives. By holding organizations liable for torts committed by employees, but not by independent contractors, vicarious liability discourages organizations from asserting direct control over agents, even when control is the efficient way to induce optimal care. Organizations governed by vicarious liability also do not employ all cost-efficient tools available to them to induce efficient care-taking by independent contractors because organizations do not maximize profits by inducing efficient care. Indeed, vicarious liability encourages organizations to undermine the effect of individual tort liability by hiring judgment-proof independent contractors.
INTRODUCTION
Tort liability is essential to the effective functioning of a free market economy because it encourages people who impose risks on others to take cost-justified precautions to reduce the expected costs of their activities. In order for tort liability to fulfill its promise, it must provide efficient incentives to organizations, as well as individuals. Torts often are caused by individuals working for, and under the influence of, organizations (generally corporations). These organizations are not passive bystanders, but instead ultimately determine whether agents strive to take cost-effective precautions against harm.
