Om du vill ha fred, förbered dig på krig : en studie i den militära styrkans betydelse

Denna uppsats kretsar kring att pröva hur en av de främsta företrädarna för den realistiska skolan, förklarar de amerikanska anfallen mot Afghanistan (2001) och Irak (2003). Hans namn är Robert Kagan och uppsatsen syftar till ge en realists tolkning till varför USA handlade som man gjorde. Man måste därför försöka uppfatta världen utifrån USA:s horisont och försöka tolka samt sätta sig in i den amerikanska positionen på den internationella arenan. Problemformuleringarna kretsar kring att få insikt i grundstenarna i Kagans teori, samt hur Kagans grundsyn skiljer sig gentemot den idealistiska. Vidare hur USA:s militära styrka, enligt Kagan, påverkar dess beteende på den internationella arenan, men även hur Kagan ser på USA:s kommande globala engagemang. Robert Kagans bok Om paradiset och makten USA och Europa i den nya världsordningen kommer att utgöra fundamentet i studien. I boken kretsar bl.a. Kagans resonemang kring att USA och Europa distanserar från varandra, men även kring militär styrka. Därför ger boken oss en väldigt bra bild av USA:s position på den internationella arenan. Kagans resonemang vävs sedan ihop med kritik, realism, idealism och geopolitik. Slutsatsen blir att grundstenarna i Kagans resonemang återfinns i den s.k. realismteorin, men även till viss del i geopolitiken. Han sätter stor vikt vid militära medel och ser staterna som de mest betydelsefulla aktörerna, samt ser världen som allmänt hotfull. Han realistiska resonemang grundas på amerikanska spelregler och ledarskap på den internationella arenan. Skillnaden mellan Kagans grundsyn och den idealistiska bottnar främst i idealisternas fokusering på integration mellan stater. Vidare att de sätter tilltro till internationell rätt, samt har ett mer multilateralt förhållningssätt till omvärlden. Kagan menar vidare att starka stater är mer villiga att använda tvång och hot i internationella relationer. De bedömer dessutom hot och risker annorlunda jämfört med svagare stater. Enligt Kagan beter sig USA som en internationell sheriff på den globala arenan och beteendet bottnar i militär styrka. Vidare anser Kagan att USA har haft samma kurs i flera århundraden. USA har expanderat in i Europa och Asien och aldrig dragit sig tillbaka. Man hade redan före den 11 september 2001 fokuserat på Kina som motspelare. Dessutom, menar Kagan, att USA varit villiga att satsa på ny militär teknik, vilken kan förändra krigföringen. Han skriver även att både Clinton och Bushadministrationen varit grundade på att USA är en nödvändig nation, samt att amerikaner vill beskydda och sprida det liberala systemet i världen.

Relative durations of post-vocalic consonants in readaloud Spanish by native Swedish L2-learners

Prosody is said to be a persistent feature in foreign accents, particularly in the speech of adult learners. Native Swedish speakers have been reported to lengthen vowels in Spanish as well as post-vocalic consonants in English and German, more than native speakers of the respective languages. The aim of the present study is to examine whether native Swedish learners of Spanish produce increased postvocalic consonant durations in a reading aloud exercise. The text contains certain words that could be expected to trigger complementary consonant lengthening in native Swedish speakers. The result shows that there is no general tendency for native Swedes to lengthen post-vocalic consonants more than native speakers of Spanish in the present speech material. There are examples of longer consonant durations in the speech of the native,Swedish subjects, but it could be a coincidence. A conclusion is that the text used in the study, and probably Spanish as a language, contains few words that are ideal for triggering lengthening of post-vocalic consonants in native Swedish speakers.

Fred: An approach to generating real, correct, reusable programs from proofs

In this paper we describe our system for automatically extracting "correct" programs from proofs using a development of the Curry-Howard process. Although program extraction has been developed by many authors, our system has a number of novel features designed to make it very easy to use and as close as possible to ordinary mathematical terminology and practice. These features include 1. the use of Henkin's technique to reduce higher-order logic to many-sorted (first-order) logic; 2. the free use of new rules for induction subject to certain conditions; 3. the extensive use of previously programmed (total, recursive) functions; 4. the use of templates to make the reasoning much closer to normal mathematical proofs and 5. a conceptual distinction between the computational type theory (for representing programs)and the logical type theory (for reasoning about programs). As an example of our system we give a constructive proof of the well known theorem that every graph of even parity, which is non-trivial in the sense that it does not consist of isolated vertices, has a cycle. Given such a graph as input, the extracted program produces a cycle as promised.

How national culture on consumers' decision-making styles: a comparative study among Americans, Brazilians, Chinese, and japanese in the purchase of cell phones.

The influence of the national culture on consumer decision-making styles is investigated using a sample of Americans, Brazilians, Chinese, and Japanese consumers who have purchased a cell phone in the past three years. To make the research possible, a survey was used as a method of data collection. It relates Hofstede’s cultural classification typology with Sproles and Kendall’s consumer style inventory (CSI). The multivariate analysis of variance (MANOVA) results indicate six decision-making styles together with other consumer behavioral characteristics that can be used to distinguish and profile consumers who purchase cell phones. Empirical findings reveal that among Americans, Brazilians, and Japanese; Americans are the most quality conscious, brand conscious, innovative, and hedonistic shoppers; Brazilians are the most loyal, and Japanese, the most confused by overchoice consumers. Conceptual contributions and managerial implications are discussed.

Temperature and Scarification Effects on the Germination of Syagrus picrophylla Seeds, a Brazilian Native Palm

Syagrus picrophylla belongs to the Arecaceae family. Its propagation is made by seeds; however there is a lack of information in the literature about its seed germination. The objective of this work was to evaluate the effects of temperature and scarification on the germination of S. picrophylla seeds. The experiment was carried out at the State University of São Paulo, Jaboticabal Campus, Brazil. The experimental design was entirely randomized in a factorial arrangement 5 x 2 (five temperature conditions combined with or without mechanical scarification. The number of germinated seeds that showed primary root protrusion was noted daily, and when the germination was stabilized, the germination (%G) and germination rate (GR) were calculated. The analysis of variance (ANOVA) was carried out for means comparing by the Tukey test at 5% confidence level. It was concluded that the greatest %G were obtained at 20-30 degrees C (62%) and 25-35 degrees C (59%) alternated temperatures; %G and GR were similar for both scarified and non-scarified seeds, and there was a faster germination at 20-30 degrees C alternated temperature.

African-Derived mitochondria in South American native cattle breeds (Bos taurus): Evidence of a new taurine mitochondrial lineage

This article reports the nucleotide diversity within the control region of 42 mitochondrial chromosomes belonging to five South American native cattle breeds (Bos taurus). Analysis of these data in conjunction with B. taurus and B. indicus sequences from Africa, Europe, the Near East, India, and Japan allowed the recognition of eight new mitochondrial haplotypes and their relative positions in a phylogenetic network. The structure of genetic variation among different hypothetical groupings was tested through the molecular variance decomposition, which was best explained by haplotype group components. Haplotypes surveyed were classified as European-related and African-related. Unexpectedly, two haplotypes within the African cluster were more divergent from the African consensus than the latter from the European consensus. A neighbor-joining tree shows the position of two haplotypes compared to European/African mitochondrial lineage splitting. This different and putatively ancestral mitochondrial lineage (AA) is supported by the calibration of sequence divergence based on the Bos-Bison separation. The European/African mitochondria divergence might be subsequent (67,100 years before present) to that between AA and Africans (84,700 years before present), also preceding domestication times. These genetic data could reflect the haplotype distribution of Iberian cattle five centuries ago.

Can Eucalyptus invade native forest fragments close to commercial stands?

Some Eucalyptus species are widely used as a plantation crop in tropical and subtropical regions. One reason for this is the diversity of end uses, but the main reason is the high level of wood production obtained from commercial plantings. With the advancement of biotechnology it will be possible to expand the geographical area in which eucalypts can be used as commercial plantation crops, especially in regions with current climatic restrictions. Despite the popularity of eucalypts and their increasing range, questions still exist, in both traditional planting areas and in the new regions: Can eucalypts invade areas of native vegetation, causing damage to natural ecosystems biodiversity?The objective of this study it was to assess whether eucalypts can invade native vegetation fragments in proximity to commercial stands, and what factors promote this invasive growth. Thus, three experiments were established in forest fragments located in three different regions of Brazil. Each experiment was composed of 40 plots (1 m(2) each one), 20 plots located at the border between the forest fragment and eucalypts plantation, and 20 plots in the interior of the forest fragments. In each experimental site, the plots were paired by two soil exposure conditions, 10 plots in natural conditions and 10 plots with soil exposure (no plant and no litter). During the rainy season, 2 g of eucalypts seeds were sown in each plot, including Eucalyptus grandis or a hybrid of E. urophylla x E. grandis, the most common commercial eucalypt species planted in the three region. At 15, 30, 45, 90, 180, 270 and 360 days after sowing, we assessed the number of seedlings of eucalypts and the number of seedlings of native species resulting from natural regeneration. Fifteen days after sowing, the greatest number of eucalypts seedlings (37 m(-2)) was observed in the plots with lower luminosity and exposed soil. Also, for native species, it was observed that exposed soil improved natural germination reaching the highest number of 163 seedlings per square meter. Site and soil exposure were the factors that have the greatest influence on seed germination of both eucalypt and native species. However, 270 days after sowing, eucalypt seedlings were not observed at any of the three experimental sites. The result shows the inability of eucalypts to adapt to condition outside of their natural range. However, native species demonstrated their strong capacity for natural regeneration in forest fragments under the same conditions where eucalypts were seeded. (C) 2011 Elsevier B.V.
