Purpose: This study explored the effects of corporate top executives’ intellectual capital on organizational effectiveness and business performance and determined whether these effects vary from the factors included in Inglehart’s cultural values. Design/methodology/approach: A large group of corporate executives (n=900) were included in this study (450 each from China and the U.S.). Inglehart’s cultural values were established as moderating variables. A path analysis using EQS6b was conducted to verify the hypothesis. Findings: The findings indicate that the sub-elements of intellectual capital are strong drivers of a company’s organizational effectiveness. The results showed that human, customer, and structural capitals affect organizational effectiveness positively. Compared with traditional versus secular-rational values and survival versus self-expression values, intellectual capital had significant effect on a company’s organizational effectiveness and business performance. Research limitations/implications: Scarce research has been conducted on intellectual capital. Even though intellectual capital is a key marketing concept that should not be ignored by today’s companies and CEOs, very little empirical research has been conducted to test its theoretical framework. Originality/value: The study showed that the cultural dimension is closely connected to the development of intellectual capital in companies or to firms’ business performance. Companies that aim to compete or are already competing in overseas markets should consider adopting business strategies that incorporate cultural values into their intellectual capital.

Background: To analyze the expression of estrogen receptors (ER), progesterone receptors (PR), C-erbB-2 and Ki-67 in endometrial carcinoma (EC) and their relationships with the clinicopathological features. Materials and Methods: Sixty-seven EC samples, 53 normal endometrial samples and 53 atypical hyperplasia endometrial samples were all selected in Shaanxi Provincial People's Hospital from Jun., 2012 to Jun., 2014. The expression of ER, PR, C-erbB-2 and Ki-67 in EC tissue, normal endometrial tissue and atypical hyperplasia endometrial tissue was respectively detected using immunohistochemical SP method. The relationships between the expression of ER, PR, C-erbB-2 and Ki-67 and the patients' clinicopathological features as well as their correlations in EC tissue were also analyzed. Results: The positive expression rates of ER and PR in EC tissue were 44.8% and 41.8%, respectively, dramatically lower than in atypical hyperplasia endometrial tissue and normal endometrial tissue (P<0.01). The positive expression rates of C-erbB-2 and Ki-67 in EC tissue were 80.6% and 64.2%, respectively, significantly higher than in atypical hyperplasia endometrial tissue and normal endometrial tissue (P<0.01). In EC tissue, the expression of ER and PR was closely associated with the differentiated degrees and depth of myometrial invasion (P<0.05), while that of C-erbB-2 and Ki-67 with the clinical staging, differentiated degrees, depth of myometrial invasion and presence or absence of lymph node metastasis (P<0.05). Spearman correlation analysis further displayed that the expression of ER was positively correlated with PR (r=0.393, P=0.001), but negatively with C-erbB-2 and Ki-67 (r=-0.469, P=0.000; r=-0.329, P=0.007); The expression of PR was negatively correlated with C-erbB-2 and Ki-67 (r=-0.273, P=0.025; r=-0.251, P=0.041), but that of C-erbB-2 positively with Ki-67 (r=0.342, P=0.005). Conclusions: Abnormal expression of ER, PR, C-erbB2 and Ki-67 might play an important role in endometrial malignant transformation and cell differentiation, so their joint detection is likely to be a comprehensive combination of immune factors, which is of great importance for EC prognosis.

Cadmium manganese telluride (CdMnTe or CMT), a compound semiconductor, is considered a promising material for the fabrication of high-performance room-temperature x-ray and gamma-ray detectors. The presence of material defects, e.g., high density of Te inclusions, has been a long-standing issue in CMT crystals grown by various Bridgman methods, since these defects degrade the device performance via charge-trapping. To address this issue, we employed the modified floating-zone method (MFZ) to grow CMT crystals and obtained as-grown crystals free of Te inclusions. This represents a new and distinct feature, absence of Te inclusions, compared to CMT crystals grown by Bridgman methods. White-beam x-ray diffraction topography (WBXDT) measurements demonstrated the existence of a high stress field within the MFZ-grown CMT crystals, which originates from the steep temperature gradient near the growth interface. Furthermore, we achieved a resistivity of 109 Ωcm for the MFZ-grown CMT crystals. The low-temperature photoluminescence (PL) measurements show that the intensity of the dislocation-related Y band is much higher than that of the principal exciton peaks, (D0,X) and (A0,X), confirming that the crystalline quality is affected by the high stress field. A long-term in-situ or post-growth thermal annealing will help to release such stress to improve the crystalline quality.

Power-to-gas (P2G) technique realizes the two-way coupling for the integrated electricity and natural gas systems, which provides an eff ective way for wind power accommodation based on its operating characteristic. Therefore, a new economic low-carbon clean dispatching of power system containing the power to gas (P2G) considering the comprehensive infl uence of the multi-price factor is proposed. Firstly, the P2G operation and carbon trading mechanism models are established. Secondly, the goal is to minimize the sum of thermal power generation costs, gas turbine power generation costs, carbon trading cost, wind abandonment penalty cost, and P2G operating costs and taking into account the comprehensive impact of multiple price factors and the security constraints of the natural gas network and the power network. Then, the improved particle swarm optimization algorithm is used to solve the model. Finally, the rationality and eff ectiveness of the proposed model are verifi ed through the analysis of calculation examples, and it is proved that the conversion of electricity to gas can eff ectively improve the wind power absorption capacity of the grid, which provides a reference for the low-carbon dispatch operation of the integrated energy system.

<P><I>Brassica rapa</I> plants are highly important as vegetables, sources of oilseeds and fodder crop. Here, we developed 450 unigene derived microsatellite (UGMS) markers in <I>B. rapa</I> using unigenes downloaded from the National Center for Biotechnology Information database. Of the 450 UGMS primer pairs, 428 (95.1%) produced repeatable and reliable amplifications of expected size in at least one parental line of <I>B. rapa</I>, and 70 UGMS markers gave 72 polymorphic loci between the two contrasting parental lines. Cross-species transferability analysis of these 70 polymorphic UGMS markers in five other cultivated <I>Brassica</I> species showed varying transferability rates ranging from 82.9% in <I>B. nigra</I> to 97.1% in <I>B. juncea</I> and <I>B. napus</I>, and overall 53 UGMS markers amplified targets in all five species. The <I>B. rapa</I> linkage map was constructed using the 72 UGMS polymorphic loci and 154 previously developed SSRs. The newly developed UGMS markers and linkage map in this study would help in future studies to better understand the organization and evolution of <I>Brassica</I> genomes with respect to unigenes, in addition to mapping, tagging and cloning of economically important trait QTL/gene(s) and marker-assisted breeding in <I>Brassica</I> crops.</P>

The inheritance of leaf and heading-related traits in Chinese cabbage (Brassica rapa ssp. pekinensis) are poorly understood since only a handful of studies of these traits are available till date. In this study, QTL mapping was done for seven leaf and heading related traits that includes gross weight, number of non-wrapper leaves, head weight, head length, head width,head length/head width ratio, and the number of head-forming leaves in 139 F3 families derived from a cross between two diverse Chinese cabbage lines, ‘501’ with small head and ‘601’ with large head. A total of 27 QTL spread over the nine linkage groups were identified for seven leaf and head-related traits, many of which showed major effects clustered in A2, A4,A6, and A8. The results provided a better understanding of the genetic factors controlling leaf and head-related traits in Chinese cabbage.
Generating unconventional wind flow in an actively controlled multi-fan wind tunnel
Wei Cui,Lin Zhao,Shuyang Cao,Yaojun Ge 한국풍공학회 2021 Wind and Structures, An International Journal (WAS Vol.33 No.2
In this study, an iteration-based method to simulate two typical examples of unconventional wind flow in a multi-fan wind tunnel is described: skewed non-Gaussian turbulence and sinusoidal type transient gust. The air flows are generated by 120 actively controlled fans arranged in a 10 wide by 12 high matrix. Time-varying voltages signals can be imported into the fans' servomotors, then corresponding wind flow can be produced in this wind tunnel. At first, the target wind speeds time series are converted to voltages signals, which are input into the fans' motor next, and then the initial wind flow generated can be measured. Then the wind speeds time series to be input are adjusted according to the differences between the target winds speeds and measured flow speeds. The above procedure is iteratively repeated until the measured wind flow is gradually close to the targets. At last, both non-Gaussian turbulence and transient gust can be simulated with satisfied precision after several iterations.

Water pollution caused by intensive use of organic dyes has become an increasingly serious problem recently. Green and efficient processes are desperately needed to remove persistent organic pollutants from waste waters. Herein, Ag nanoparticles loaded ZnO hollow microspheres were synthesized through a simple solvothermal method and used as a photocatalyst for dye degradation. The calculated band gap of Ag/ZnO — 5% (2.97 eV) is much narrower than that of pure ZnO (3.37 eV). The obtained Ag/ZnO samples show a remarkable photocatalytic activity in photodegradation of Rhodamine B (RhB) under simulated sunlight irradiation. The degradation efficiency of RhB for Ag/ZnO — 5% is 98.8% after 100 min irradiation while only 52.8% degradation rate is obtained over pure ZnO. The enhancement is attributed to the exposed active ZnO (001) plane and the surface plasmon resonance (SPR) effect of Ag nanoparticles that promote the separation of photogeneated electrons and holes.
