Opis:
Due to speed-dependent centrifugal forces, the support of the torque, static mechanical stress introduced by manufacturing processes the laminated core of rotating electrical machines is exposed to considerable mechanical stress. The resulting stress distribution changes the magnetic properties of the electrical steel. To take this into account, a magnetization model is constituted on the basis of vector magneto-mechanical measurements that include the magnetic permeability as a function of the mechanical stress and the angle between magnetization - and the maximum principal stress direction. Subsequently, the model is integrated into the finite element simulation of a permanent magnet excited synchronous machine at different rotational speeds.

Opis:
This paper synthesizes cross-sectional studies of the effect of proficiency on second language (L2) pragmatics to answer the synthesis question: Does proficiency affect adult learners’ pragmatic competence? Findings have revealed an overall positive proficiency effect on pragmatic competence, and in most cases higher proficiency learners have higher pragmatic competence. However, increased proficiency does not guarantee a native-like pragmatic performance because proficiency effect varies depending on the nature of target pragmatic features such as types of speech acts (degrees of directness and conventionality) (e.g., Cook & Liddicoat, 2002; Félix-Brasdefer, 2007), modalities of pragmatic performance (comprehension and production) (e.g., Bradovi-Harlig, 2008, 2009), social variables involved in task situations, such as social status (e.g., Allami & Naeimi, 2011), social distance (e.g., Maeshiba, Yoshinaga, Kasper, & Ross, 1996), and power relationship (e.g., Al-Gahtani & Roever, 2012). Moreover, proficiency effect is mediated by contextual variables such as length of stay in the target language community (e.g., Shardakova, 2005; Taguchi, 2011, 2013; Xu, Case, & Wang, 2009).

Opis:
At the national symposium on the reform of state-owned enterprises, General Secretary Xi Jinping gave important instructions that state-owned enterprises are important forces in strengthening the country’s overall strength and safeguarding the common interests of the people. Therefore, the country must make state-owned enterprises „stronger, better, and bigger”. Huge objections arose in the academic field. This article thoroughly analyzes China’s state-owned economy from the perspective of Marx’s historical materialism, national productivity, and social development, and clarifies the historical status and role of China’s state-owned economy. At the same time, this article comprehensively analyzes the economic significance of making state-owned enterprises „stronger, better, and bigger” from the perspective of total factor productivity, and proposes that since the state-owned economy is backed up by the state, investing in technology research and development has its advantages. However, because the state-owned economy is biased toward administrative instructions, it often lacks efficiency, so if the state-owned economy wants to become „stronger, better, and bigger”, it must undergo reforms in terms of management efficiency.

Opis:
In this paper, we investigate the impact of environmental regulations on employment in China. We apply a quasi-natural experiment on the revision of Water Pollution Prevention and Control Law in 2008 (WPPCL2008), and we analyze manufacturing sectors’ reaction to WPPCL2008 by using a differences-in-differences approach based on China’s thirty five sectors at the 2-digit level from 2003 to 2014. Our results show that although environmental regulations can reduce waste-water emissions, at the same time cause a decrease in employment. The results suggest that stringent environmental regulation is not cost free. Furthermore, this finding contradicts the popular view that the effect of Chinese legislation enforcement is insignificant.
W tym artykule analizujemy wpływ środowiskowych regulacji prawnych na zatrudnienie w Chinach. Przygotowaliśmy eksperyment odnoszący się do poprawionej Ustawy o zapobieganiu zanieczyszczeniom wody i kontroli jakości wód z 2008 r. (WPPCL2008) i przeanalizowaliśmy reakcję na zmienione prawo ze strony sektora produkcyjnego korzystając z metody DID (differences-in-differences), uwzględniając 35 sektorów występujących w Chinach i 2-cyfowy poziom pomiędzy 2003 a 2014 r. Otrzymane rezultaty pokazują, że surowe regulacje środowiskowej nie są wolne od kosztów. Co więcej, okazuje się, że są one sprzeczne z poglądem, że chińskie prawodawstwo jest nieistotne.

Opis:
This study aims to discuss the impacts of intellectual capital and corporate character on sustainable competitive advantage. The structural equation model is used to analyze the relationships between intellectual capital, corporate character and sustainable competitive advantage, which are mediated by technological innovation and business model innovation, based on a survey of 377 observations in China. The empirical results indicate that the intellectual capital and corporate character are as the doors that enterprises can open to acquire technological innovation and business model innovation, which are beneficial to achieving and maintaining sustainable competitive advantage. The findings provide some implications for entrepreneurs that their enterprises should focus on the coordination and balance of intellectual capital and corporate character for better achieving the perfect integration of cost leading strategy and differentiation strategy on the basis of mixing technological innovation and business model innovation together. Such strategy helps enterprises to realize sustained growth. This study provides scholars a new binary perspective to explore the source of sustainable competitive advantage.
Niniejszy artykuł ma na celu omówienie wpływu kapitału intelektualnego i podejścia korporacyjnego na trwałą przewagę konkurencyjną. Przyjęty model równania strukturalnego posłużył do analizy związków między kapitałem intelektualnym, podejściem korporacyjnym i trwałą przewagą konkurencyjną, w czym pośredniczą innowacje technologiczne i innowacje modelu biznesowego. Badania oparto na 377 przykładach z Chinach. Uzyskane wyniki wskazują, że kapitał intelektualny i podejście korporacyjne są ‘drzwiami’, które przedsiębiorstwa mogą otworzyć, aby uzyskać innowacje technologiczne i innowacje w modelu biznesowym, korzystne dla osiągnięcia i utrzymania trwałej przewagi konkurencyjnej. Artykuł dostarcza przedsiębiorcom pewnych wskazówek, aby ich przedsiębiorstwa koncentrowały się na koordynacji i równowadze kapitału intelektualnego oraz podejścia korporacyjnego, aby lepiej osiągnąć pełną integrację strategii wiodącej pod względem kosztów i strategii różnicowania na podstawie wprowadzanych innowacji technologicznych i innowacji modelu biznesowego. Taka strategia pomaga przedsiębiorstwom osiągnąć zrównoważony wzrost. Przeprowadzone badania pokazują uczonym nową perspektywę binarną, pozwalającą odkryć źródło zrównoważonej przewagi konkurencyjnej.

Opis:
The fracture of shape memory alloys is distinct from that of conventional metals, owing to the coexistence and interaction of multiple special features such as martensitic transformation, dislocation-induced plasticity, thermomechanical coupling and others. In this paper, the impact of thermomechanical behavior upon the crack initiation of a NiTi shape memory alloy under Mode I loading is investigated numerically and verified experimentally. A constitutive model incorporating phase transformation, plasticity and thermomechanical coupling is established. Via backward Euler integration and finite-element implementation, the longitudinal strain, martensite volume fraction and temperature field in the vicinity of the crack tip are furnished. The effects of grain size and loading rate on J-integral are revealed. The grain size dependence of crack initiation is non-monotonic. For the samples with grain sizes of 1500 nm, 18 nm and 10 nm, the shielding effect takes place in front of the crack. Additionally, the anti-shielding effect is detected for samples with grain sizes of 80 nm and 42 nm. The parametric study shows that loading rate imposes limited influence on J-integral, which is attributed to a small scale transformation. The decrement of yield stress and the increment of transformation hardening modulus can alleviate the anti-shielding effect and arouse the shielding effect upon crack initiation. The presented results shed light on the design and fabrication of high toughness phase transformable materials.

Opis:
A finite-strain constitutive model of a superelastic NiTi shape memory alloy is proposed in this paper. Via backward Euler implicit integration scheme and the incorporation of material softening, the model is implemented into finite element code to reproduce a Lüders like deformation of a superelastic NiTi. The simulation results are in agreement with the experimental results, indicating that the constitutive model can reasonably predict the mechanical behavior of a superelastic NiTi. A parametric study further verifies that the magnitude of softening modulus has a significant effect on the stress-strain response and Lüders-like deformation of a superelastic NiTi.

Opis:
At present, the cushion thickness of composite foundation under rigid base is mostly selected by the experience of the engineer, which is of great arbitrariness. In order to improve this problem, the optimum design method of cushion thickness is proposed by theoretical research. First, the stress diffusion line in the cushion is assumed to be a quadratic curve, and the critical diffusion thickness of the pile top stress is obtained. Then, by analyzing the relative deformation between soil and pile, pile top penetration into the critical cushion thickness is proposed. Finally, based on the relationship between stress ratio of pile to soil and cushion thickness, the calculation method of optimum cushion thickness is put forward. The application of engineering cases shows that the proposed method has better calculation results, which attests to the correctness of the method. The method can be used for the optimal design of cushion thickness of single-type-pile or multi-type-pile composite foundation.

The bulk commodity, different with the retail goods, has a uniqueness in the location selection, the chosen of transportation program and the decision objectives. How to make optimal decisions in the facility location, requirement distribution, shipping methods and the route selection and establish an effective distribution system to reduce the cost has become a burning issue for the e-commerce logistics, which is worthy to be deeply and systematically solved. In this paper, Logistics warehousing center model and precision marketing strategy optimization based on fuzzy method and neural network model is proposed to solve this problem. In addition, we have designed principles of the fuzzy method and neural network model to solve the proposed model because of its complexity. Finally, we have solved numerous examples to compare the results of lingo and Matlab, we use Matlab and lingo just to check the result and to illustrate the numerical example, we can find from the result, the multi-objective model increases logistics costs and improves the efficiency of distribution time.

Thesis. After the handover of Hong Kong’s sovereignty to China in 1997, the Hong Kong Special Administrative Region government stipulated a trilingual (English, Cantonese, and Mandarin) and biliterate (English and Chinese) policy, in order to include Mandarin as an additional co-official language together with the original English and Cantonese. Until the handover, the use of Mandarin was restricted in British colonial Hong Kong. Since the handover, however, Mandarin and its users have experienced some resistance by local Hong Kong people. Method. In an attempt to better understand this resistance and its implications, this study adopts Pierre Bourdieu’s field, habitus, and capital theory, to analyse the anti-Mandarin discourse that has prevailed in the ensuing two decades. Via narrative inquiry, this study explains the habitus of four Mandarin speaking teachers, while especially noting their clashes with the anti-Mandarin discourse, and the symbolic violence they suffered in the field.     Conclusion. The study concludes with a reflection on the clash between the teachers’ struggles with the discourse from a postcolonial perspective, and it also considers the legal issues involved in protecting mainland Chinese as a minority in Hong Kong.
