Broadly tunable high-power InAs/GaAs quantum-dot external cavity diode lasers

A record broadly tunable high-power external cavity InAs/GaAs quantum-dot diode laser with a tuning range of 202 nm (1122 nm-1324 nm) is demonstrated. A maximum output power of 480 mW and a side-mode suppression ratio greater than 45 dB are achieved in the central part of the tuning range. We exploit a number of strategies for enhancing the tuning range of external cavity quantum-dot lasers. Different waveguide designs, laser configurations and operation conditions (pump current and temperature) are investigated for optimization of output power and tunability.

Transzformációs válság: Rögös út az információs kapitalizmus felé

A 2007-es nyári eseményekkel indult és 2008-ban már látható formát öltött válság semmiképpen sem egy a szokványos recessziók sorában. A szubprime válságként ismert visszaesés egy több évtizedes léptékű transzformációs válság része, és nem érthető meg ezen a kontextuson kívül. A transzformációs válság annak a következménye, hogy az ipari társadalom tömegtermékeket produkáló, rutinfolyamatokon nyugvó merev rendszere fokozatosan átadja helyét a gyorsan változó, innovatív tudásgazdaságnak. A tanulmány sorra veszi ennek az új gazdaságnak a fontosabb elemeit, amelyek közös tulajdonsága a bizonytalanság, illetve a stabilitás hiánya. Azok a hagyományos piacbefolyásoló eszközök (például a keynesi keresletnövelés), amelyek kiszámíthatóan működtek a tömegtermékek piacán és jól kalkulálható tömegreakciókat váltottak ki, az információgazdasági környezetben lényegesen veszítenek erejükből. A munkavállalók, a gazdasági szervezetek és a kormányok nehezen alkalmazkodnak az új gazdaság természetéhez: a gyors változásokhoz és az állandósult bizonytalansághoz. A szerző a munkapiaci anomáliák: az új, magasabb természetes rátát produkáló munkanélküliségnek és a tehetséges munkavállalók hiányának az együttes jelenlétén keresztül mutatja be az alkalmazkodás viszontagságait. A tanulmány a kormányzati alkalmazkodás nehézségeinek és az állami szabályozás megoldatlan dilemmáinak az elemzésével zárul a szellemi termékek piacán.

An Examination of the AP United States History Exam Free Response Section

Michael S. Henry examined the first 30 years of the AP United States History exam’s essay section. This study examined changes that have occurred over the last 20 years by classifying questions into one of six categories and found little change in the types of essays used during this timeframe.

Global compilation of benthic data sets I

Approaches to quantify the organic carbon accumulation on a global scale generally do not consider the small-scale variability of sedimentary and oceanographic boundary conditions along continental margins. In this study, we present a new approach to regionalize the total organic carbon (TOC) content in surface sediments (<5 cm sediment depth). It is based on a compilation of more than 5500 single measurements from various sources. Global TOC distribution was determined by the application of a combined qualitative and quantitative-geostatistical method. Overall, 33 benthic TOC-based provinces were defined and used to process the global distribution pattern of the TOC content in surface sediments in a 1°x1° grid resolution. Regional dependencies of data points within each single province are expressed by modeled semi-variograms. Measured and estimated TOC values show good correlation, emphasizing the reasonable applicability of the method. The accumulation of organic carbon in marine surface sediments is a key parameter in the control of mineralization processes and the material exchange between the sediment and the ocean water. Our approach will help to improve global budgets of nutrient and carbon cycles.

Visita interprofissional da cardiologia: uma estratégia de educação interprofissional na área da saúde na Universidade Federal do Rio Grande do Norte

The interprofessional education still represents a great challenge for the health education. This paper aims at implementing the Interprofessional Cardiology Visit (VIC, acronym in Portuguese) as a teaching strategy for the interprofessional education in the undergraduate and graduate courses of UFRN (Federal University of Rio Grande do Norte, acronym in Portuguese). It is a prospective and exploratory study held from March 2013 to November 2014, in the cardiology department of HUOL (Portuguese acronym for Onofre Lopes University Hospital), including health professionals from the mentioned hospital (doctor, psycologist, physiotherapist, dentist, social assistant, nutritionist, pharmacist and nurse), undergraduate and graduate students from the health courses of UFRN. The study happened in three parts: interprofessional activity planning; Implementation of the activity “Interprofessional Cardiology Visit (VIC)”; and Activity evaluation, this last one was made through focus groups. The process of planning and implementation of the VIC was described during the implementation phase: 60 meetings in which 1324 participants discussed one specific patient per meeting. After each case presentation, an interprofessional discussion was held, pointing out each professional’s specific point of view towards improving the overall care of that discussed patient. From the focus group analysis, five categories emerged: Recognition of previous participations in interprofessional activities; Conceptual vision of interprofessional activities; Impacts of the VIC to the patient’s care; Contributions of VIC to the professional training; and Challenges of VIC continuation. The making and planning of VIC process has reached its goals, despite of some health professional’s participation not being systematic due to work overload, such as the nurses’ case, as well as schedule difficulties. The VIC was praised as a successful experience and considered an initiative with positive impact for improving the care of patients with heart diseases. It is clear, from analyzing the discourses, that the VIC is a strategy which positively impacts both the care and the teaching. However, some difficulties remain, such as the lack of human resources and the challenge of making it systematic.
