Measurements of bone mineral density (BMD) of the proximal femur (including femoral neck, Ward's triangle and trochanteric region) were compared with the Singh index grading in 40 normal subjects (20 male, 20 female) and in 116 patients (18 male, 98 female) referred for assessment of possible osteoporosis. Additionally, the BMD and the Singh index of 12 cadaver specimens (6 male, 6 female) of the proximal femur were compared with each other and with the histomorphology of the femoral necks of the specimens. Although there was a good correlation of Singh index with BMD in the group of male patients with suspected osteoporosis and in the series of bone specimens, there was a poor correlation in the group of female patients as well as in the normal controls and in the patient population as a whole. There was also poor correlation of Singh index values with histomorphologic data, whereas the BMD measurements correlated well with the amount of calcified bone found histologically in the femoral necks of the bone specimens. We conclude that the Singh index cannot be used to predict BMD of the proximal femur accurately.

Purpose – The purpose of this paper is to take a strategic perspective on how MNEs in the retail sector decide to enter a new market. Drawing on transaction cost theory, the contingency approach and resource-based theory, the implications of the interplay between global strategy, cultural distance and entry mode strategies are examined by means of an analysis of Carrefour’s global expansion. Design/methodology/approach – To account for the shortcomings of prior research, a hypothesis in the relationship between entry modes and cultural distance is tested empirically using a sample of 44 foreign market entries by Carrefour over the 40 last years. The paper uses a quantitative approach, i.e., logistic regressions. To measure cultural distance, the authors rely on the GLOBE dimensions and the Kogut-Singh Index. Findings – The findings suggest a positive relationship between a resource commitment, entry mode strategy and cultural distance for Carrefour. However, these findings are contrary to the mainstream argument that high cultural distance is related to entry strategies based on relatively low resource commitment. The authors explain these findings by integrating a cultural distance perspective with Carrefour’s overall global expansion strategy. Research limitations/implications – Because of the chosen research approach, the research results may lack generalizability. Practical implications – The paper provides insights into why prior research on cultural distance and entry modes has yielded mixed results. From a strategic viewpoint, the paper stresses the particularities of the retail sector and how retailers try to account for cultural distance in their entry mode decisions. Originality/value – By focussing on a single company instead of a meta-analysis, the analysis demonstrates how the search for strategic consistency and the particularities of the retail sector reverse a well-investigated theoretical assumption. The main originality of the paper is that it shows the implications of the interplay between cultural distance and entry mode as being part of the retail firm’s overall global expansion strategy.

Background: The treatment of Intertrochanteric fractures in the elderly osteoporotic patient is still controversial. The aim of this study was to compare the outcomes of proximal femoral nailing (PFN) and a distally-fixed non-modular monoblock fluted long-stem hemiarthroplasty (HA) in elderly patients with an osteoporotic intertrochanteric fracture. Methods: This retrospective study included patients who had undergone surgery for an unstable intertrochanteric fracture. The patients were separated into PFN and HA groups. The demographic features of the 2 groups were compared. All patients were evaluated using the Singh index, ASA score, AO/OTA classification, Harris Hip Score (HHS), and Parker and Palmer mobility score. Results: The most common complications were nonunion (12.0%) and cut-out of the screw (10.7%) in the PFN group, and dislocation of the prosthesis (6.7%) and wound infection (5.7%) in the HA group. Overall, the 2-year mortality rate was 29.3%. Mortality, particularly within the first 3 months, was 2.4 times higher in the PFN Group than in the HA group (40% vs. 19.75%). Although the HHS was significantly higher in the first year for the HA group, no significant difference was seen between the 2 groups at 24 months. Conclusions: Although PFN and HA have similar good outcomes at 2 years, HA allows earlier mobilisation and has fewer complications and a lower mortality rate.

Purpose International trade flows of cultural goods have grown noticeably in the past few decades and the development of cultural products trade has been an important issue in the international business field. Therefore, this study aims to explore how per capita gross domestic product, distance, culture, Internet penetration and other factors affect the trade of cultural products. Design/methodology/approach The paper focuses on the international trade in cultural goods of China, Japan and Korea with other countries. To analyze the essential reason, the study has applied the classical gravity model along with variables, which mainly represent global connectedness to investigate which variables have the most impact on trade in cultural products. Findings The result shows that in terms of China, cultural similarity boosts the volume of trade volume with other countries, however, for South Korea and Japan, cultural similarity does not have a significant impact. On top of cultural similarity, individual cultural value dimension differences between countries show mixed results for each country and their directions of trade. Global connectedness, on the other hand, is not congruent with the general expectations of previous studies. Research limitations implications Due to the limited time for data collection, the research was done with a relatively small country list with a limited number of cultural good items. Second, the Kogut and Singh index is one of the most popular measures based on cultural dimension deviation. It is based on the Euclidean calculation method used by most scholars but some scholars believe that the Euclidean method has some shortcomings. Third, the authors do not actively promote robust testing after regression analysis this work would be carried out in the future. Finally, using the four basic cultural dimensions proposed by Hofstede in 1980 may be another limitation. Practical implications First, the authors should further promote the establishment of the China-Japan-South Korea Free Trade Area. The three countries should formulate special policies to favor the trade of cultural products and support the development of the cultural industry. Additionally, the three sides should also set up a joint research center to explore the issue of improving the international competitiveness of cultural products trade and find common solutions. And the three countries should further open their doors within the reasonable range, relax the restrictions on tourism and trade visas. Originality/value The analysis provides some different results as the previous papers. Distance variables show positive effect on trade which defines that long distance between countries do no matter on trade in cultural goods. Moreover, the variables of tourism receipt shows that global connectedness positively effects on trade. The cultural variables of the KS composite index show opposite result with the conventional logic which advocates that cultural dissimilarity enhances trade in cultural goods.
