Multinational firms in the world wine industry: an investigation into the determinants of most-favoured locations

The objective of the paper is to identify some of the determinants of foreign investment of the largest multinational enterprises (MNEs) operating in the wine industry. The factors that drive firms to invest abroad and those that determine the location of those investments are examined in the case of the world wine industry. The list of the largest MNEs has been compiled using financial databases and company websites. Spearman rank correlation values are calculated between the ranking of the location popularity of host countries and the ranking of the independent variables or indices for the same period. The results of this study have some important implications. They indicate that location-specific advantages of host countries do provide an explication of the internationalization of firms in some preferred countries rather than others.     

Cyclic nucleotides attenuate lipid peroxidation-mediated neuron toxicity

Recent studies suggest that increased lipid peroxidation and lipid peroxidation products, such as 4-hydroxynonenal (HNE), contribute to neuronal loss in conditions associated with oxidative stress. The focus of the present study was to determine possible neuroprotective effects of elevated cyclic nucleotide levels against lipid peroxidation and HNE-mediated neural toxicity. Application of 8-bromo derivative analogs of cAMP or cGMP resulted in attenuation of HNE-induced increases in mitochondrial calcium, reactive oxygen species, and neuron loss. Similar results were obtained when neural cells were pretreated with the phosphodiesterase inhibitors zaprinast or isobutylmethylxanthanine (IBMX). These data are consistent with a possible neuroprotective role for elevated cyclic nucleotide levels in disorders associated with increases in lipid peroxidation and HNE.     

Trabecular Bone Analysis in CT and X-Ray Images of the Proximal Femur for the Assessment of Local Bone Quality

Currently, conventional X-ray and CT images as well as invasive methods performed during the surgical intervention are used to judge the local quality of a fractured proximal femur. However, these approaches are either dependent on the surgeon's experience or cannot assist diagnostic and planning tasks preoperatively. Therefore, in this work a method for the individual analysis of local bone quality in the proximal femur based on model-based analysis of CT- and X-ray images of femur specimen will be proposed. A combined representation of shape and spatial intensity distribution of an object and different statistical approaches for dimensionality reduction are used to create a statistical appearance model in order to assess the local bone quality in CT and X-ray images. The developed algorithms are tested and evaluated on 28 femur specimen. It will be shown that the tools and algorithms presented herein are highly adequate to automatically and objectively predict bone mineral density values as well as a biomechanical parameter of the bone that can be measured intraoperatively.

Exploring metaskills of knowledge-creating inquiry in higher education

The skills of knowledge-creating inquiry are explored as a challenge for higher education. The knowledge-creation approach to learning provides a theoretical tool for addressing them: In addition to the individual and social aspects in regulation of inquiry, the knowledge-creation approach focuses on aspects related to advancing shared objects of inquiry. The development of corresponding metaskills is suggested as an important long-term goal for higher education; these pertain, simultaneously to the individual, collective, and object-oriented aspects of monitoring inquiry. Taking part in collaborative inquiry toward advancing a shared knowledge object is foreseen as a means to facilitate the development of metaskills; the present study examines one undergraduate university course in psychology with that aim. The data consisted of a database discourse and students’ self-reflections after the course, examined by qualitative content analysis. Three analyses investigated discourse evolution, knowledge advancement, and the challenge of the inquiry practices. The student-groups differed markedly in their engagement in the inquiry efforts. The study gave insights concerning novel challenges evoked by knowledge-creating inquiry, relating in particular to commitment, epistemic involvement, dealing with confusion, and the iterative nature of knowledge advancement. We propose the following implication for educational practices: Although dealing with uncertainty and areas beyond one’s expertise, as well as engaging in self-directed collaborative inquiry, may seem overly demanding for students, such experiences are decisive for developing one’s skills in dealing with open-ended knowledge objects in a longer time frame.

有关处理棕色珍珠的简要报道

几年前,在市场上出现了一种处理的棕色珍珠新产品。以往对珍珠颜色的处理是将其漂成白色和染成粉红色、黄色和黑色。一些珍珠供应商认为,这种新品种珍珠是通过某种漂白处理使得深色调的塔希提黑珍珠的颜色变亮形成。测试发现,来自不同生产商的部分棕色珍珠经过了染色处理。令人惊讶的是,尽管这些珍珠在市场上是作为处理品销售,但消费者却欣然地接受并称其为“巧克力珠”。

Binary semiconductor In2Te3 for the application of phase-change memory device

Nonvolatile phase-change memory devices with 500 nm contact hole based on In₂Te₃ were successfully fabricated by using focused ion beam, pulsed laser deposition, and dc magnetic sputtering techniques. In₂Te₃ films were characterized by using differential thermal analysis, X-ray diffraction, and UV–vis diffuse absorption spectroscopy, respectively. The devices can be switched between high and low resistance states repeatedly with the programmed voltage pulses. The reset operation (crystalline to amorphous) was done by the voltage pulse with a magnitude of 3.5 V and a duration of 30 ns, and the set operation (amorphous to crystalline) was done by the voltage pulse with a magnitude of 1.4 V and a duration of 100 ns. A dynamic resistance switching ratio (OFF/ON ratio) of 3.2 × 10³ has been obtained.
