The globalization of world politics: an introduction to international relations (Fifth edition)
Now in its fifth edition, this internationally successful title has been fully revised and updated in light of recent developments in world politics. New chapters on post colonialism and post structuralism as well as increased emphasis on the global financial crisis, forced migration, diplomacy and religion ensure The Globalization of World Politics remains the most comprehensive introduction to International Relations available. Expert contributors provide accessible but stimulating insights into the history, theory, structures and key issues in IR, which are ideally suited to those coming to the subject for the first time. Students and lecturers are further supported by a cutting-edge Online Resource Centre

The globalization of world politics: an introduction to international relations (seventh edition)
'The Globalization of World Politics' is the market leading introduction to International Relations, written by an unrivalled line-up of experts in their fields. Spanning history, theory, structures and processes, and international issues, it offers the most comprehensive coverage of IR available and maps closely onto introductory courses, as well as being suitable as a valuable reference for the duration of an IR degree. Integrated learning features, including case studies and questions, a brand new debating feature and end of chapter questions, are all carefully tailored to the needs of students approaching IR for the first time. And new to this edition are four brand new chapters including: Feminism, Race, International Organizations, and NGOs

NâCadherin Targeted Melanin Nanoparticles Reverse the EndothelialâMesenchymal Transition in Vascular Endothelial Cells to Potentially Slow the Progression of Atherosclerosis and Cancer
Endothelialâmesenchymal transition (EndoMT) of
vascular
endothelial cells has recently been considered as a key player in
the early progression of a variety of vascular and nonvascular diseases,
including atherosclerosis, cancer, and organ fibrosis. However, current
strategies attempting to identify pharmacological inhibitors to block
the regulatory pathways of EndoMT suffer from poor selectivity, unwanted
side effects, and a heterogeneous response from endothelial cells
with different origins. Furthermore, EndoMT inhibitors focus on preventing
EndoMT, leaving the endothelial cells that have already undergone
EndoMT unresolved. Here, we report the design of a simple but powerful
nanoparticle system (i.e., N-cadherin targeted melanin nanoparticles)
to convert cytokine-activated, mesenchymal-like endothelial cells
back to their original endothelial phenotype. We term this process
âReversed EndoMTâ (R-EndoMT). R-EndoMT allows the impaired
endothelial barriers to recover their quiescence and intactness, with
significantly reduced leukocyte and cancer cell adhesion and transmigration,
which could potentially stop atheromatous plaque formation and cancer
metastasis in the early stages. R-EndoMT is achieved on different
endothelial cell types originating from arteries, veins, and capillaries,
independent of activating cytokines. We reveal that N-cadherin targeted
melanin nanoparticles reverse EndoMT by downregulating an N-cadherin
dependent RhoA activation pathway. Overall, this approach offers a
different prospect to treat multiple EndoMT-associated diseases by
designing nanoparticles to reverse the phenotypical transition of
endothelial cells

Introduction to global politics
The first U.S. textbook to offer students a truly global approach, Introduction to Global Politics brings together an expert team of international scholars who provide a current, engaging, non-U.S. perspective on international relations. The authors and editors help students to identify patterns, to apply theories, and to see "the whole chessboard" of global politics. The book's unique organization facilitates this global approach by dividing typical course coverage into several core areas of study--"Foundations," "Theories," "Actors," and "Issues"--allowing not only for maximum teaching flexibility but also for more thoughtful classroom discussions on various theories, transnational actors, and timely global issues. Adding interesting features and critical thinking questions throughout each chapter, the authors take the global approach one step further, encouraging students to develop their own informed worldviews
mRNA transcription of candidate genes for thermal adaptation in the crimson-spotted rainbowfish.
Total mRNA was extracted from laboratory bred and reared individuals (F1); parents were wild-caught and originated from the Brisbane River. At 6 months of age, individuals from each family group were subjected to one of two thermal treatments for a duration of 80 days. Rearing tank (Tank), sex (Sex), thermal treatment group (Treat) individual identifier (animal), parents (DAM & SIRE) and full-sib family group (Fam) are provided for each individual. Immediately following thermal treatment, fish were euthanized and total mRNA extracted from liver tissues.
Transcript abundance was estimated via quantitative real-time PCR. LinRegPCR was used to convert raw CT values into estimates of initial/starting mRNA concentrations (N0). Initial mRNA concentrations were standardized relative to the geometric mean of two reference genes (geomean.REFS). Standardized values of candidate genes occupy the final 12 columns; gene symbols (column headings) are the same as those used in the accompanying article (McCairns et al. 2016)

Spectroscopic Imaging and Power Dependence of Near-Infrared to Visible Upconversion Luminescence from NaYF<sub>4</sub>:Yb<sup>3+</sup>,Er<sup>3+</sup> Nanoparticles on Nanocavity Arrays
The spatial variations in upconversion
luminescence from NaYF<sub>4</sub>:Er<sup>3+</sup>,Yb<sup>3+</sup> nanoparticles embedded in
PMMA on Au nanocavity arrays are investigated over a wide range of
excitation powers, spanning the nonlinear and saturation power-dependence
regimes. Spatially resolved upconversion spectra on these arrays show
a minimum of â3Ă luminescence enhancement compared to
the adjacent smooth Au surface under high-intensity excitation, with
progressively higher enhancement ratios, up to 30Ă, at excitation
intensities below 100 W/cm<sup>2</sup>. It is found that the average
upconversion luminescence enhancement, obtained by spectroscopic imaging
and far-field measurements, can be almost entirely accounted for by
an effective multiplicative shift in the excitation intensity, <i>P</i><sub>eff</sub> = <i>F</i>·<i>P</i>, which is robust over 5 orders of magnitude variation in excitation
intensity. We reconcile this constant excitation enhancement factor, <i>F</i> = 4.46, with the wide range of observed luminescence enhancement
factors, ranging from 3Ă to 30Ă, using an analytical model
for a three level system, and by numerically solving a system of coupled
rate equations for the Yb<sup>3+</sup>, Er<sup>3+</sup> system. By
analyzing the statistical distributions of luminescence intensities
in the spectroscopic images on and off the nanocavity arrays, estimates
of the luminescence enhancement factor independent of fluctuations
in nanoparticle density are obtained. The results clearly relate observed
enhancement factors to the kinetics of the energy-transfer upconversion
process, suggesting the primary upconversion enhancement from these
substrates is in the Yb<sup>3+</sup> absorption channel, and demonstrate
these self-assembled enhancing substrates as a low-cost and scalable
route toward efficient near-infrared to visible upconversion at low
excitation intensities
