Abstract Strings and ropes are a proven, common fisheries and aquaculture construction elements outside the US. Using them as scaffolding also enables a diversity of ocean sensing, communications and architectures, including our goal of sentinel reefs. Packaging of electronics is key to enabling such structures and systems. Our research is towards a demonstrable science-engineering-informed framework for 3D habitat designs critical to stock fish development & coastal protection. These ‘nature-inspired’ reef infrastructures, can enable novel instrumented ‘reef observatories’ capable of collecting real-time ecosystem data. Embedding lighting and electronic elements into reef systems are the first systems in development. This new approach of bringing light to the underwater world for optical sensing, communication and even a new breed of underwater robotic vehicle is an interdisciplinary research activity which integrates principles of electronic packaging, and STEM with art/design.

Solid Lipid

One of the situations in the treatment of disease is the delivery of efficacious medication of appropriate concentration to the site of action in a controlled and continual manner. Nanoparticle represents an important particulate carrier system, developed accordingly. Nanoparticles are solid colloidal particles ranging in size from 1 to 1000 nm and composed of macromolecular material. Nanoparticles could be polymeric or lipidic (SLNs). Industry estimates suggest that approximately 40% of lipophilic drug candidates fail due to solubility and formulation stability issues, prompting significant research activity in advanced lipophile delivery technologies. Solid lipid nanoparticle technology represents a promising new approach to lipophile drug delivery. Solid lipid nanoparticles (SLNs) are important advancement in this area. The bioacceptable and biodegradable nature of SLNs makes them less toxic as compared to polymeric nanoparticles. Supplemented with small size which prolongs the circulation time in blood, feasible scale up for large scale production and absence of burst effect makes them interesting candidates for study. In this present review this new approach is discussed in terms of their preparation, advantages, characterization and special features.

Cross-national comparisons that assess dimensions of health system performance indicate that the US provides higher rates of revascularization procedures than France and other developed nations, but we believe these findings are misleading. In this paper, we compare the use of these procedures in the US, France and their two world cities, Manhattan and Paris. In doing so, we address a number of limitations associated with existing cross-national comparisons of heart disease treatment. After adjusting for the prevalence of disease in these nations and cities, we found that residents of France aged 45–64 years receive more revascularization procedures than residents of the US and that Parisians receive more revascularizations than residents of Manhattan. Older residents 65 years and over (65+) in the US receive more of these procedures than their French counterparts, but the differences are not nearly as great as previous studies suggest. Moreover, our data on Manhattan and Paris where the population and level of health resources are more comparable, indicate that older Parisians obtain more revascularization procedures than older Manhattanites. Finally, we found that the use of revascularization procedures is significantly lower in Manhattan among persons without private health insurance and among racial and ethnic minorities.

This article is founded on the basic assumption that Europe taken as a whole possesses all the necessary resources to combat successfully any non-European competitor in the fields of technology, provided that it solves the management problem of organizing the coordination of those resources. At present, the author argues, they are dispersed and so underexploited. To contribute to the solution of this core problem, he sets out a new approach to research collaboration, using the example of the German–French Institute for Automation and Robotics to show ways in which HEIs can cooperate internationally to provide industry with what it needs to be truly competitive.

Kaleckian Model

As is well known, the closure of the canonical Neo-Kaleckian model is an endogenous rate of capacity utilisation. To allay concerns of Harrodian instability one response has been to endogenise the normal rate to effective demand pressures. Recent contributions have stressed microfoundations for an adjustment in the normal rate towards the actual rate. The new approach focuses on shiftwork and redefines capacity utilisation as the average workweek of capital. This paper examines whether the new concept of capacity utilisation can provide a firmer basis for endogeneity in the normal rate. It argues that the assumption of variability in the normal shift system cannot be generalised across manufacturing industries, while the potential relevance for non-manufacturing industries is unknown. Another concern is that long-run trends in the average workweek of capital and aggregate demand do not coincide. The paper also finds that the long-run trend in the US Federal Reserve's index of capacity utilisation for the manufacturing sector is not flat as frequently claimed. Instead, there is a downward trend from the mid 1960s, which matches the slowdown in aggregate demand.

Interpretive Methods

Practice theorists favor interviews and participant observations in their study. Using insights from anthropological works on bureaucratic texts, in this article we develop methodological tools to complement these interpretive methods of data collection. We suggest a way to trace practices by systematically looking through both the content of documents and their form. We probe this approach with an analysis of 408 diplomatic cables sent by the US Embassy in Dar es Salaam, Tanzania in 2005–2009 and subsequently released by Wikileaks. We draw on these documents to tell two related stories about diplomatic practices: the first about epistemic practices and how the cables privilege certain voices and types of knowledge over others, and the second about diplomatic culture, where the cables serve as evidence of the powerful socialization processes that diplomats are subject to. This contributes to International Relations (IR) with a new approach for systematically analyzing written documents to uncover international practices.

Unanimous Approval

More than five years out from its implementation, we still know relatively little about how members of the US military and its ancillary institutions are responding to the repeal of Don’t Ask, Don’t Tell. Contrary to what one might expect given the long history of LGBTQ antipathy in the military, I found in interviews with Boston area Reserve Officer Training Core (ROTC) cadets unanimous approval for the repeal of DADT. When pressed to explain why there was so much homogeneity of favorable opinion regarding the repeal, interviewees repeatedly offered the same explanation: that Boston, in particular, is such a progressive place that even more conservative institutions like the ROTC are spared anti-gay sentiment. They imagined the Southern and/or rural soldier they will soon encounter when they enter the US military, one who represents the traditionally homophobic attitudes of the old military in contrast to their more enlightened selves. This “metronormative” narrative has been critiqued elsewhere as inadequate for understanding the relationship between sexuality and place; this article contributes to that critique by taking a new approach. Rather than deconstruct narratives of queer rurality, as the majority of metronormativity scholarship has done, I deconstruct these narratives of urban queer liberation. I find that such narratives mask the murkier realities of LGBTQ attitudes in urban contexts and allow residents like the ROTC cadets in this study to displace blame about anti-gay prejudice to a distant Other, outside of their own ranks.

Content analysis is a quantitative method that uses human coders to apply a set of valid measurement rules to reduce manifest features of content to numeric data in order to make replicable, generalizable inferences about that content. Because the method is applied to human artifacts, it has generic advantages that apply whether doing quantitative content analysis or qualitative textual or rhetorical analysis. For example, analyzing communication content is an unobtrusive research activity that is unaffected by self-report biases. However, it is critical to differentiate content analysis as a distinct, quantitative, social-scientific method using human coders from other methods of analyzing content: this is done in order to call attention to the method’s unique strengths and weaknesses. A weakness of content analysis is that assigning content to numeric categories loses some of the richness of human communication. A strength of content analysis is that it reduces complex communication phenomenon to numeric data, allowing researchers to study broader phenomenon than would be possible via methods that rely on close reading. Furthermore, probabilistic sampling allows researchers to draw inferences about a given communication phenomenon without observing all cases and processes. Reliability testing also helps ensure that results have greater precision and are replicable. Although content analysis developed out of the US scholarly community building on code breaking during the Second World War, it is now used around the world. However, most of the available texts in non-English languages are translations from texts originally written in English. The following sections provide references that give scholars, both novices and those who are experienced in using content analysis, a strong foundation in the method, especially as it applies to studying media content. The references focus on content analysis applied to theory, units of measurement, sampling, and reliability. They also suggest core texts and journals that are good outlets for content analysis scholarship. Compared to other methods based on measuring implicit attitudes (e.g., survey research), content analysis has been the subject of much less methodological research aimed at improving the method itself. So the following discussion also calls attention to those areas where more empirical research may help advance the method, providing young and experienced scholars alike an opportunity to make their own contributions to the method and improve measurement.
