Can Light-Shaped Visual Prompt Promote Individuals’ Lights off Behaviors More Effectively than Ordinary One?  [PDF]
Zhuli Feng, Fuzhen Zhang
Psychology (PSYCH) , 2019, DOI: 10.4236/psych.2019.101006
Abstract: Lights off behavior makes contribution to energy saving, meeting the realistic requirements of building a sustainable society. Several studies investigated the effectiveness of prompt on energy saving behavior, but few focused on how to make prompt more effective by “packaging”. In this current study, light-shaped prompt was designed with inspiration from light itself and 18 washrooms were studied in an ABAB-B method to verify whether the light-shaped visual prompt could promote lights off behaviors more than ordinary one, with a duration of 9 weeks, during which a one-week follow-up was conducted 4 weeks after ABAB was finished, to investigate the sustained effect of light-shaped visual prompt on lights off behaviors. Study showed that light-shaped visual prompt could exert more effective influence on lights off behaviors than the ordinary one. Individuals’ lights off behavior persisted throughout the follow-up period. This study provided a new perspective for improving the effectiveness of prompt. But further study on more well-designed visual prompt of diverse shape was necessary for the maximization of effectiveness and expanded application.

An operator equality involving a continuous field of operators and its norm inequalities
Mohammad Sal Moslehian,Fuzhen Zhang
Mathematics , 2008,
Abstract: Let ${\mathfrak A}$ be a $C^*$-algebra, $T$ be a locally compact Hausdorff space equipped with a probability measure $P$ and let $(A_t)_{t\in T}$ be a continuous field of operators in ${\mathfrak A}$ such that the function $t \mapsto A_t$ is norm continuous on $T$ and the function $t \mapsto \|A_t\|$ is integrable. Then the following equality including Bouchner integrals holds \begin{eqnarray}\label{oi} \int_T|A_t - \int_TA_s{\rm d}P|^2 {\rm d}P=\int_T|A_t|^2{\rm d}P - |\int_TA_t{\rm d}P|^2 . \end{eqnarray} This equality is related both to the notion of variance in statistics and to a characterization of inner product spaces. With this operator equality, we present some uniform norm and Schatten $p$-norm inequalities.
Angles, triangle inequalities, correlation matrices and metric-preserving and subadditive functions
Diego Castano,Vehbi E. Paksoy,Fuzhen Zhang
Mathematics , 2014,
Abstract: We study the triangle inequalities for angles (with different definitions) and present inequalities concerning the entries of correlation matrices through the positivity of $3\times 3$ matrices. We extend our discussions to the inequalities concerning the triangle triplets with metric-preserving and subadditive functions.
Positivity of Partitioned Hermitian Matrices with Unitarily Invariant Norms
Chi-Kwong Li,Fuzhen Zhang
Mathematics , 2014,
Abstract: We give a short proof of a recent result of Drury on the positivity of a $3\times 3$ matrix of the form $(\|R_i^*R_j\|_{\rm tr})_{1 \le i, j \le 3}$ for any rectangular complex (or real) matrices $R_1, R_2, R_3$ so that the multiplication $R_i^*R_j$ is compatible for all $i, j$, where $\|\cdot\|_{\rm tr}$ denotes the trace norm. We then give a complete analysis of the problem when the trace norm is replaced by other unitarily invariant norms.
An inequality for tensor product of positive operators and its applications
Xaixia Chang,Vehbi E. Paksoy,Fuzhen Zhang
Mathematics , 2014,
Abstract: We present an inequality for tensor product of positive operators on Hilbert spaces by considering the tensor product of operators as words on certain alphabets (i.e., a set of letters). As applications of the operator inequality and by a multilinear approach, we show some matrix inequalities concerning induced operators and generalized matrix functions (including determinants and permanents as special cases).
Chomskyan Linguistics and the Scientific Methodology in Linguistic Study
Fuzhen Si
Asian Social Science , 2009, DOI: 10.5539/ass.v5n5p82
Abstract: This article is mainly concerned with Chomskyan linguistics, especially its methodology. The author of the paper argues against Shi Yuzhi(2005) and holds that although the relation between theoretical hypotheses and observations is, in some sense, like chickens and eggs and therefore to say that this paradigm is a top-down approach that is bottom-up one is too simple, theoretical hypothesis does function as directive force in scientific research and can be prerequisite to proper and effective experiments and observations. “Observations are meaningless unless we know what regularity they are supposed to illustrate.” As for the stability of linguistics theory, the author thinks that linguistics, just like other sciences such as chemistry and physics, in order to prove specific ideas and hypothesis, scientists normally change their experimental programs frequently. What changed in Chomksyan linguistics are the experimental programs, the change from Government and Binding theory to the Minimalist Program as an example; what changed are technical details. And the hypothesis and main point of views never changed in general.
Association of ADAM33 gene polymorphisms with adult allergic asthma and rhinitis in a Chinese Han population
Dongju Su, Ximei Zhang, Hong Sui, Fuzhen, Lianhong Jin, Jing Zhang
BMC Medical Genetics , 2008, DOI: 10.1186/1471-2350-9-82
Abstract: Six polymorphic sites (V4, T+1, T2, T1, S1, and Q-1) were genotyped in 128 patients with AR, 181 patients with AS, and 151 healthy controls (CTR). Genotypes were determined by the polymerase chain restriction fragment length polymorphism (PCR-RFLP) method. Data were analyzed using the chi-square test with Haploview software.The single nucleotide polymorphisms (SNPs), V4 G/C, T+1 A/G, and T1 G/A, of the ADAM33 gene may be the causal variants in AR, whereas ADAM33 V4 G/C, T2 A/G, T1 G/A, and Q-1A/G may participate in the susceptibility of AS.These results suggest that polymorphisms of the ADAM33 gene may modify individual susceptibility to AR and AS in a Chinese Han population.Rhinitis is defined as inflammation of the nasal mucosa and is characterised by nasal discharge, blockage, sneezing, and itching [1,2]. Asthma is a chronic inflammatory disorder of the airway which causes recurrent episodes of wheezing, breathlessness, chest tightness, and coughing in susceptible individuals. These episodes are usually associated with widespread, but variable airflow obstruction that is often reversible, either spontaneously or with treatment. The inflammation also causes an associated increase in existing bronchial hyper-responsiveness (BHR) to a variety of stimuli [1,2]. Epidemiologic studies have consistently shown that asthma and rhinitis often coexist in the same patients in every region of the world [3-5], suggesting the concept of 'one airway, one disease.' The basic premise is that rhinitis and asthma represent the manifestations of one syndrome in two parts of the respiratory tract [6]. In order to raise awareness of the theory of 'one airway, one disease,' the Allergic Rhinitis and Its Impact on Asthma (ARIA) Workshop Group publication proposes three considerations for patients with allergic respiratory disease [7].ADAM33 is the first reported asthma-susceptible gene identified by positional cloning [8]. ADAM33 is a complex molecule, the expression of which is largely

Abstract: Background Behcet's disease is known as a recurrent, multisystem inflammation and immune-related disease. Protein tyrosine phosphatase non-receptor 22 (PTPN22) is a key negative regulator of T lymphocytes and polymorphisms of the PTPN22 gene have been shown to be associated with various immune-related diseases. The present study was performed to assess the association between PTPN22 polymorphisms and Behcet's disease in two Chinese Han populations. Methodology/Principal Findings A total of 516 patients with ocular Behcet's disease and 690 healthy controls from two Chinese Han populations were genotyped by the polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method for three single nucleotide polymorphisms (SNPs). Hardy-Weinberg equilibrium was tested using the χ2 test. Genotype frequencies were estimated through direct counting. Allele and genotype frequencies were compared between patients and controls using logistic regression analysis. The results revealed that there was no association between the tested three PTPN22 SNPs (rs2488457, rs1310182 and rs3789604) and ocular Behcet's disease (p>0.05). Categorization analysis according to the clinical features did not show any association of these three polymorphisms with these parameters (p>0.05). Conclusions/Significance The investigated PTPN22 gene polymorphisms (rs2488457, rs1310182 and rs3789604) were not associated with ocular Behcet's disease in two Chinese Han populations, and showed that it may be different from other classical autoimmune diseases. More studies are needed to confirm these findings for Behcet's disease in other ethnic backgrounds.
