Wisdom, cultural synergy, and social change: A Taiwanese perspective

This study examined the relationships among wisdom, cultural synergy (i.e., incorporating lessons learned from different cultures), and social change by re-analyzing 220 “wisdom incidents” (i.e., real-life displays of wisdom) collected from 1997 to 2003 from 66 Taiwanese adults nominated as wise individuals (Yang, 2008a). We addressed these questions empirically with a mixed-methods approach: (a) “What are the features of cultural synergy involved in the Taiwanese wisdom nominees’ narratives about their displays of wisdom?”; and (b) “How are real-life displays of wisdom related to cultural synergy and social change?” Wisdom is defined as a real-life process that entails three components: (a) cognitive integration—an individual incorporates separate or conflicting ideas to form an integrated idea; (b) embodying actions—the individual acts to implement the unified idea; and (c) positive effects for oneself and others—the individual\u27s actions generate positive effects for the self and others. The 220 wisdom incidents were re-analyzed qualitatively by young Taiwanese for themes related to cultural synergy and lessons learned from culture; the incidents were re-evaluated quantitatively by young Taiwanese for indications of wisdom, cultural synergy, and social change. A model proposing relationships among wisdom, cultural synergy, and social change was then evaluated using path analysis. Results, which may be generalized to young Taiwanese, show that displays of wisdom had (a) a direct relationship with cultural synergy and social change; and (b) an indirect relationship with social change through cultural synergy. Findings suggest that what the Taiwanese wisdom nominees learned from both their own culture and other cultures is significantly related to cultural synergy which, in turn, is significantly related to promoting social change

Behaviour and design of duplex stainless steel bolted connections failing in block shear

Duplex stainless steel (DSS) is an emerging construction material for structural engineering, which is featured with high mechanical strength and superior corrosion resistance. Compared with considerable research on DSS structural members, available research is relatively limited for structural joints/connections between these members. In line with this concern, this paper presents a comprehensive experimental and numerical study of duplex stainless steel bolted connections (DSSBCs), focusing on the behaviour and design related to block shear failure. Eleven specimens are tested to investigate the effect of different bolt arrangements on the block shear behaviour. Furthermore, a detailed numerical study was performed as a supplement to the experimental tests, where the anisotropic mechanical properties of DSS are considered in the finite element modelling. Based on the test and analysis results, it is found that the block shear failure mode of DSSBCs resembles that of carbon steel bolted connections, which can be characterised as necking of the tensile section and yielding of the shear sections. Using the experimental and numerical data obtained in this and previous studies, the applicability of various block shear design methods to stainless steel bolted connections is assessed. An updated design method is proposed for predicting the block shear capacity of duplex and austenitic stainless steel bolted connections. A proper partial safety factor/resistance factor is suggested for the proposed method based on the results of reliability analyses

Observations of foetal heart veins draining directly into the left and right atria

Evaluation of semiserial sections of 14 normal hearts from human foetuses of gestational age 25–33 weeks showed that all of these hearts contained thin veins draining directly into the atria (maximum, 10 veins per heart). Of the 75 veins in these 14 hearts, 55 emptied into the right atrium and 20 into the left atrium. These veins were not accompanied by nerves, in contrast to tributaries of the great cardiac vein, and were negative for both smooth muscle actin (SMA) and CD34. However, the epithelium and venous wall of the anterior cardiac vein, the thickest of the direct draining veins, were strongly positive for SMA and CD34, respectively. In general, developing fibres in the vascular wall were positive for CD34, while the endothelium of the arteries and veins was strongly positive for the present DAKO antibody of SMA. The small cardiac vein, a thin but permanent tributary of the terminal portion of the great cardiac vein, was also positive for SMA and CD34. A few S100 protein-positive nerves were observed along both the anterior and small cardiac veins, but no nerves accompanied the direct dra- inage veins. These findings suggested that the latter did not develop from the early epicardiac vascular plexus but from a gulfing of the intratrabecular space or sinus of the atria. However, the immunoreactivity of the anterior cardiac vein suggests that it originated from the vascular plexus, similar to tributaries of the great cardiac vein.

Bearing and tearout of austenitic and duplex stainless steel bolted connections

Due to the unique material characteristics of stainless steel, the bearing and tearout behaviour of stainless steel bolted connections can be different from that of carbon steel bolted connections. Such difference has been gradually recognised in recent design provisions for stainless steel structures. However, it is noteworthy that the existing design methods were mainly developed for austenitic and ferritic stainless steel bolted connections. Their applicability to duplex stainless steel bolted connections is questionable. Moreover, comparing to the bearing failure of stainless steel connections, less attention has been paid to the tearout failure, as well as the combined bearing and tearout failure in multi-bolt connections. To fill these gaps, an experimental and numerical study is carried out on the bearing/tearout behaviour and design of stainless steel bolted connections. The experimental programme includes 22 connection specimens with either single-bolt or multi-bolt configurations, made of austenitic or duplex stainless steel. The experimental tests are supplemented by a comprehensive numerical parametric study with more than 200 individual models, performed based on a validated finite element modelling technique. The obtained test and numerical results are used to assess the effects of different design parameters, as well as the applicability of existing design methods. It is concluded that the ultimate bearing/tearout resistances of austenitic and duplex connections are not simply proportionate to the ultimate strengths of the two materials. Given the same geometric design, the bearing resistance of a duplex connection is considerably higher than that of an austenitic connection, despite the similar ultimate strengths of the two materials. This difference in bearing performance is attributed to the different strain-hardening characteristics of austenitic and duplex materials, as well as the premature shear cracking in austenitic connections that leads to insufficiently developed strain-hardening. In comparison, the tearout resistances of austenitic and duplex connections with the same geometry are much closer, since the smaller end distance leads to more uniform deformations and more completely developed strain-hardening. Moreover, the combined bearing and tearout resistance of multi-bolt connections is found to be lower than the sum of the respective resistances of individual bolts. Finally, an updated design method is proposed that can accurately predict the bearing/tearout resistance of both austenitic and duplex stainless steel bolted connections. Proper partial factors are determined for the proposed method based on a reliability analysis

Effects of Allelic Variation in Glutenin Subunits and Gliadins on Baking-Quality in Near-isogenic Lines of Common Wheat cv. Longmai 19

Two lines, L-19-613 and L-19-626, were produced from the common wheat cultivar Longmai 19 (L-19) by six consecutive backcrosses using biochemical marker-assisted selection. L-19 (Glu-D1a, Glu-A3c/Gli-A1?; Gli-A1? is a gene coding for unnamed gliadin) and L-19-613 (Glu-D1d, Glu-A3c/Gli-A1?) formed a set of near-isogenic lines (NILs) for HMW-GS, while L-19-613 and L-19-626 (Glu-D1d, Glu-A3e/Gli-A1m) constituted another set of NILs for the LMW-GS/gliadins. The three L-19 NILs were grown in the wheat breeding nursery in 2007 and 2008. The field experiments were designed using the three-column contrast arrangement method with four replicates. The three lines were ranked as follows for measurements of gluten strength, which was determined by the gluten index, Zeleny sedimentation, the stability and breakdown time of the farinogram, the maximum resistance and area of the extensogram, and the P andWvalues of the alveogram: L-19-613 > L-19-626 > L-19. The parameters listed above were significantly different between lines at the 0.05 or 0.01 level. The Glu-D1 and Glu-A3/Gli-A1 loci had additive effects on the gluten index, Zeleny sedimentation, stability, breakdown time, maximum resistance, area, P and W values. Although genetic variation at the Glu-A3/Gli-A1 locus had a great influence on wheat quality, the genetic difference between Glu-D1d and Glu-D1a at the Glu-D1 locus was much larger than that of Glu-A3c/Gli-A1? and Glu-A3e/Gli-A1m at the Glu-A3/Gli-A1 locus. Glu-D1d had negative effects on the extensibility and the L value compared with Glu-D1a. In contrast, Glu-A3c/Gli-A1? had a positive effect on these traits compared with Glu-A3e/Gli-A1m

Effects of reducing dietary crude protein and metabolic energy in weaned piglets

The objective of this experiment was to determine the effects of a pure reduction in the dietary crude protein (CP) and metabolic energy (ME) contents on growth performance, nutrient digestibility, blood profile, faecal microflora and odour gas emission in weaned pigs. A total of 80 weaned piglets ((Landrace × Yorkshire) × Duroc) with a mean initial bodyweight (BW) of 6.8 ± 0.5 kg were randomly allotted to four treatments with four replicate pens of five piglets per pen (based on average BW) for 45 days. The dietary treatments consisted of i) CON: basal diet; ii) LME: reduction of 10% of ME in basal diet; iii) LCP: reduction of 10% of CP in basal diet; iv) MECP: reduction of 10% of CP and 10% of ME in basal diet. During the experimental period, average daily feed intake (ADFI) improved in piglets fed the LME and LCP diets, compared with those fed the CON diets. Average daily gain (ADG) and gain to feed (G : F) ratio decreased in piglets fed LCP, LME, and MECP diet, when compared with those fed the CON diet. However, during the total experimental period, ADG and G : F ratio were not affected by dietary treatment. With regard to nutrient digestibility, apparent total track digestibility (ATTD) of CP was not affected by experimental diets. The concentration of blood urea nitrogen (BUN) in blood decreased more in piglets fed LME, LCP, and MECP than those fed the CON diet. The emissions of ammonia (NH3), hydrogen sufide (H2S), and volatile fatty acids (VFAs) were lower in piglets fed LME, LCP, and MECP diet than those fed the CON diet. In conclusion, these results indicate that reduction in dietary CP and ME content did not decrease growth performance and nutrient digestibility, and they increased positive effects such as BUN and gas emission reduction.Keywords: Blood profile, digestibility, growth performance, odour emission, pi

Evaluation of fermented whole crop wheat and barley feeding on growth performance, nutrient digestibility, faecal volatile fatty acid emission, blood constituents, and faecal microbiota in growing pigs

This study was conducted to determine the effects of feeding diets with fermented whole crop wheat (FWW) and fermented whole crop barley (FWB) on growth performance, nutrient digestibility, blood constituents, faecal volatile fatty acid (VFA) emission and faecal microbiota in growing pigs. A total of 200 growing pigs were randomly allotted to five treatments with eight replicates per treatment and five pigs per replicate. Dietary treatments consisted of i) CON (basal diet), ii) 0.5% FWW (CON + 0.5% fermented whole crop wheat), iii) 1.0% FWW (CON + 1.0% fermented whole crop wheat), iv) 0.5% FWB (CON + 0.5% fermented whole crop barley), and v) 1.0% FWB (CON + 1.0% fermented whole crop barley). The digestibility of total dietary fibre was significantly higher in pigs fed FWW diets. The faecal emissions of VFA of pigs fed the fermented treatments was increased significantly compared with CON. Concentrations of cortisol and triglyceride in blood of pigs fed 1.0% FWW were significantly lower than pigs fed CON diets. The pigs fed 1.0% FWB diets had a significantly decreased level of total cholesterol in blood compared with CON. In conclusion, the current results indicated that diets supplemented with FWW and FWB could increase faecal VFA emission and reduce concentration of triglyceride and cortisol, while 0.5% and 1.0% FWW had no negative effects on growth performance, and could increase digestibility of dietary fibre in growing pigs.Keywords: Dietary fibre, faecal short-chain fatty acid emissions, fermented feed, serum parameter, swin

Geometric entangling gates for coupled cavity system in decoherence-free subspaces

We propose a scheme to implement geometric entangling gates for two logical qubits in a coupled cavity system in decoherence-free subspaces. Each logical qubit is encoded with two atoms trapped in a single cavity and the geometric entangling gates are achieved by cavity coupling and controlling the external classical laser fields. Based on the coupled cavity system, the scheme allows the scalability for quantum computing and relaxes the requirement for individually addressing atoms.Comment: 6 pages, 1 figur

Information erasure and the generalized second law of black hole thermodynamics

We consider the generalized second law of black hole thermodynamics in the light of quantum information theory, in particular information erasure and Landauer’s principle (namely, that erasure of information produces at least the equivalent amount of entropy). A small quantum system outside a black hole in the Hartle-Hawking state is studied, and the quantum system comes into thermal equilibrium with the radiation surrounding the black hole. For this scenario, we present a simple proof of the generalized second law based on quantum relative entropy. We then analyze the corresponding information erasure process, and confirm our proof of the generalized second law by applying Landauer’s principle
