Organismal duplication, inclusive fitness theory, and altruism: understanding the evolution of endosperm and the angiosperm reproductive syndrome.

For almost a century, events relating to the evolutionary origin of endosperm, a unique embryo-nourishing tissue that is essential to the reproductive process in flowering plants, have remained a mystery. Integration of recent advances in phylogenetic reconstruction, comparative reproductive biology, and genetic theory can be used to elucidate the evolutionary events and forces associated with the establishment of endosperm. Endosperm is shown to be derived from one of two embryos formed during a rudimentary process of "double fertilization" that evolved in the ancestors of angiosperms. Acquisition of embryo-nourishing behavior (with accompanying loss of individual fitness) by this supernumerary fertilization product was dependent upon compensatory gains in the inclusive fitness of related embryos. The result of the loss of individual fitness by one of the two original products of double fertilization was the establishment of endosperm, a highly modified embryo/organism that reproduces cryptically through behavior that enhances the fitness of its associated embryo within a seed. Finally, although triploid endosperm remains a synapomorphy of angiosperms, inclusive fitness analysis demonstrates that the embryo-nourishing properties of endosperm initially evolved in a diploid condition.

Moving American progress westward images of Denver and the Rockies in popular culture

"From the 1859 gold rush through the early 1900s, popular press images linked Denver’s civic development, capitalist values and culture to the Rocky Mountains. These prints of a wilderness city sending pioneers and prospectors into the Rockies appeared in national newspapers, magazines, settlement manifestos, railroad guidebooks and tourist pamphlets. Readers were saturated with illustrations associating Denver with prosperity and rejuvenated health"-

Human Rights in the Democratic People's Republic of Korea and the Future of the Troubled State after Kim Jong-Il

Since 2008, international speculation about the viability of Kim Jong-Il's leadership in North Korea has been at the forefront of diplomatic discussions. North Korea is known to be a secretive state where human rights violations abound. This paper discusses the history of leadership and government in North Korea since World War II, the current human rights situation in the country, the role of China, and potential successors to Kim Jong-Il. The ramifications of impending regime change are discussed in terms of North Korea's human rights issues and economic problems. While current efforts at diplomacy have proved ineffective, the need for concerned nations, intergovernmental organizations, and non-governmental organizations to be prepared to engage North Korea after Kim Jong-Il is imperative.

Indicators of obesity and the educational attainment of the Czech female population

The aim of this paper was to evaluate the relationship between selected indicators of obesity and the highest completed level of education in the adult female population of the Czech republic. As basic indicators of obesity, these following parameters were selected and measured via the bioimpedance method on the device InBody 720: BMI, WHR (waist-to-hip ratio), % body fat, % skeletal muscle mass, fitness score. The educational attainment of the tested women was inquired by a questionnaire. Based on the responses, we subsequently divided our sample into four categories according to the level of education: primary education, secondary education-apprenticeship, secondary education-graduate diploma, and university. The research was realized within the project CZ.1.07/2.3.00/20.0044. The measurements on the device InBody 720 and the accompanying survey were conducted between 2011-2013 in different regions of the Czech Republic. The sample consisted of 754 women divided into 3 age groups (18-39, 40-59, 60+ years). Based on the results (p<0.05), we can say that average values of the indicators obesity (BMI: 22.76, 24.88, 26.49 kg/m2, WHR: 0.85, 0.88, 0.90 and % body fat: 25.76, 30.23, 34.62%) increase with the increasing age of examined women. The average values of the fitness score (75.53, 73.86, 70.04 points) and % skeletal muscle mass (40.78, 38.15, 33.95%) decrease with increasing age. With regard to the educational attainment, women with secondary education-apprenticeship achieved the worst results. In contrast, the values in university educated women were the best in most indicators of obesity.

Mutual perceptions of Asia and the EU/Europe. Media, elite and public opinion in Singapore and Germany. EU Centre in Singapore Working Paper No. 12, December 2012

In an increasingly interlinked and interdependent world, Europe and Asia are key players. Free trade agreements (FTAs), such as the ones the EU concluded with South Korea and Singapore, are indicative of strong mutual economic interests. It is therefore timely to take a closer look at the mutual perceptions of Asians and Europeans – not only at the governmental and policymaking levels, but also in terms of public opinion and the media. Drawing on data from an extensive research project led by the National Centre for Research on Europe (NCRE), New Zealand, the empirical study in this paper assesses the mutual perceptions of the EU/Europe and Asia, and their respective actors, focusing on two countries – Germany and Singapore. It seeks to do so through an analysis of the data collected from print and broadcast media, interviews with media practitioners, and the findings from public opinion surveys.
