Norms, Values and Symbols in the Intercultural Operations of Companies

Knowledge of the importance of one country values and symbols, which given culture attaches to some elements or live situations helps when doing business on the foreign market. Values can be defined as standards or rules, which are recognized as valuable and important in life. Values are the reflection of what people really believe in and their attitudes towards the most important aspects of live. Values determine our way of thinking, behaving as well as mirror our cultural background. Symbols play an important role in the intercultural environment. Incorrect usage of some of the symbol can be equal to failure while doing business.     

Feed Output in China to Rebound

The output of animal teed is poised to rebound after seeingits first contraction in 20 years, as demand for feed increases on greater demand for meat and increased production at fish farms in the country.     

FDI in China:Policies and Economic effects

The rapid growth of the world population since 1950 and the contribution matching the GDP and the income per capita has been seen in the increase competition for FDI of the past few years. Therefore, it is well-known that FDI can contribute to economic development not only by being a source of foreign capital, but also by providing employment, opportunities, increasing competition, and most importantly transferring skills and knowledge done by spillover effects.However, these positive effects are not automatic for host countries in the long run and depend largely on the policies taking in place. Having a closer look at the People′s Republic of China(PRC) and by examining how the policies in place have attracted FDI and looking to the contributions that foreign direct invest can make to the recipient country,showing the effects in industries that are economic pushers such as the mining industry can give us the general idea. Hence, FDI has contributed positively to Chinese economic development; there are challenges in order that the People′s Republic China can effectively continue benefitting from it at a larger extent.     

FDI in the Extractive Sector:The Case of Colombia

The article present empirical evidence about the negative effects of FDI inflows over economic growth in the primary sector,in which developing countries,like most of Latin American countries,are the main exporters.One of the most important reasons for this negative relation between these two variables is the absence of spillovers in technology,knowledge,skills,etc.As probe of this negative effects,I analyze Colombia ’s strategy "Mining Engine of growth",which fits perfectly with the purpose of this study,as this Andean country is showing some symptoms of what is known as Dutch Disease and a lot of social and environmental problems related with the mining activities,especially in indigenous and natural reserves.

The journal is supported by the Chinese Association of Animal Science and Veterinary Medicine, a well-respected and established society. Animal science and animal production have been developing rapidly in China over the past 20 years. China has become the largest meat and egg producer in the world. A group of scientists and researchers have emerged in this fast growing area, pro-     

Export growth and diversification in Algeria:lessons from China’s foreign trade experience

Algeria like many of its Middle Eastern and North African(MENA) counterparts,rely heavily on the industry of fossil fuels,such as gas and petroleum.This big reliance of Algerian economy on hydrocarbon exports revenue makes it very vulnerable to external shocks.So since the late 1990s different measures had been adopted to help promote the diversification of exports,but so far the adoption of these measures,has mixed results and has failed to boost foreign trade out of Hydrocarbons exports in a significant way.But unlike Algeria,China has been the most successful developing country in this modern era of globalization.It was one of the poorest countries in the world in 1980s,and since initiating economic reform after 1978 its GDP has expanded at a steady rate over 10% and it`s foreign trade is considered as one of the most important in the world.Given these facts the purpose of this paper is to analyze,why Algeria struggles to develop and diversify its exports out of Hydrocarbons.And what are the engines of the impressive growth of china’s foreign trade,if any;lessons can Algeria take from china’s foreign trade experience.     

Effects of Dietary Starch Source on Nutrient and Energy Absorption via the Portal Vein of Growing Pigs

Four crossbred(Duroc×Landrace×Yorkshire)boars,weighing an average of 22.40 ± 1.08 kg and fitted with permanent catheters in their portal and mesenteric veins as well as their carotid artery,were utilized in a 4 × 4 latin square design experiment in order to investigate the effects of different starch sources(maize,brown rice,sticky rice,and resistant starch)on the absorption of energy sources through the portal vein.Portal blood flow averaged 30.68,28.40,29.99,and 30.12 mL/min per kg BW for pigs fed the maize,brown rice,sticky rice,and resistant starch diets,respectively,and did not differ(P0.05)between treatments.The absorptions of glucose,plasma ammonia,and total amino acids were significantly lower(P0.05)in pigs fed the resistant starch diet than pigs fed the other starch sources.In contrast,significantly(P0.05)higher amounts of propionate and total volatile fatty acids were absorbed from the portal vein of pigs fed resistant starch than pigs fed diets based on maize,brown rice,or sticky rice.In addition,significantly(P0.05)more lactic acid was absorbed from the portal vein by pigs fed the sticky rice diet than pigs fed the other three diets.The energy absorbed from the portal vein in the form of glucose and amino-N as well as the total energy absorbed was significantly(P0.05)lower in pigs fed the resistant starch diet than pigs fed the other three starch sources.In contrast,the amount of energy absorbed in the form of volatile fatty acids was significantly(P0.05)higher in pigs fed resistance starch than pigs fed the other three starch sources.The total energy absorbed through the portal vein as a percentage of the gross energy and digestible energy consumed in pigs fed maize were 50.8% and 54.6%,respectively,which were significantly(P0.05)higher than the values in pigs fed resistant starch(41.5% and 46.6% respectively).The results indicate that energy is absorbed in different forms and with different utilization efficiencies in the digestive tract of pigs as a result of feeding different starch sources.Starch sources supplying most of their energy in the form of glucose had higher energy utilization efficiencies,while starch sources supplying most of their energy in the form of volatile fatty acids or lactic acid had lower energy utilization efficiencies.

Evidence for the non-involvement of the uterus in the lifespan of the corpus luteum in the cyclic dog

Progesterone levels in peripheral blood of dogs were analysed during the cycle in which hysterectomy (n = 5) or sham surgery (n = 3) was performed as well as during the cycle of dogs (n = 5) hysterectomized at least one year prior to this study; the data were compared with the findings in control dogs (n = 3). The averages of the duration of the luteal period observed in the three experimental groups were not significantly different from those of control dogs. Immediately after surgery, the progesterone level decreased from 25 to 50% of the presurgical level, but returned to presurgical level in about four days. Prolactin levels were elevated for about 30 h after surgery. Nevertheless, the averages of the mean prolactin levels for each animal during the luteal period of the experimental groups were not significantly different from those of control dogs. It is concluded that in the dog, the uterus is not involved in the lifespan of the cyclic corpus luteum.     

The influence of the width of the saddle tree on the forces and the pressure distribution under the saddle

As there is no statistical evidence that saddle fit influences the load exerted on a horse's back, this study was performed to assess the hypothesis that the width of the tree significantly alters the pressure distribution on the back beneath the saddle. Nineteen sound horses were ridden at walk and trot on a treadmill with three saddles differing only in tree width. Kinetic data were recorded by a sensor mat. A minimum of 14 motion cycles were used in each trial. The saddles were classified into four groups depending on fit. For each horse, the saddle with the lowest overall force (LOF) was determined. Saddles were classified as "too-narrow" if they were one size (2 cm) narrower than the LOF saddle, and "too-wide" if they were one size (2 cm) wider than the LOF saddle. Saddles two sizes wider than LOF saddles were classified as "very-wide". In the group of narrow saddles, the pressure in the caudal third (walk 0.63 N/cm(2)+/-0.10; trot 1.08 N/cm(2)+/-0.26) was significantly higher compared to the LOF saddles (walk 0.50 N/cm(2)+/-0.09; trot 0.86 N/cm(2)+/-0.28). In the middle transversal third, the pressure of the wide saddles (walk 0.73 N/cm(2)+/-0.06; trot 1.52 N/cm(2)+/-0.19) and very-wide saddles (walk 0.77 N/cm(2)+/-0.06; trot 1.57 N/cm(2)+/-0.19) was significantly higher compared to LOF saddles (walk 0.65 N/cm(2)+/-0.10/ 0.63 N/cm(2)+/-0.11; trot 1.33 N/cm(2)+/-0.22/1.27 N/cm(2)+/-0.20). This study demonstrates that the load under poorly fitting saddles is distributed over a smaller area than under properly fitting saddles, leading to potentially harmful pressures peaks.
