The rapid development of information technology makes people"s lifestyles constantly changing, bringing great changes to the library building. As a product of the development of public libraries, community libraries have an important impact on community cohesion and revitalization through providing targeted learning and leisure services to residents. Under the trend of social and community development, the community library"s user-centered space must adapt to the diverse needs of community users and make the self-improvement. First of all, this study summarizes the concept of community and community libraries through literature review, and then make a theoretical investigation on the composition of user-centered space. Finally this study bases on the cases of community library buildings in the United States and Britain, and initially explores the composition of user-centered space in these libraries, and then analyzes and summarizes the architectural characteristics of it. Exploring how community can be activated and cohesive through community libraries user-centered space. Hope that this study can provide some reference to the contemporary community library design.
The Effectiveness of Extensive Reading on EFL Learners' Vocabulary Learning: Incidental versus Intentional Learning Feng Teng Forty-six students majoring in business English volunteered to take part in an extensive reading program. The learners were divided into two groups: EG, the experimental group, received instruction in methods of extensive reading plus explicit outputpushed activities, and CG, the control group, received instruction in methods of extensive reading alone. This study measured the effects of extensive reading on EFL vocabulary learning, as well as the effect of the two different instruction methods on learning receptive and productive vocabulary for the 46 learners of different vocabulary size. The research found that (a) both the two instructional methods resulted in significant gains in learners' receptive and productive vocabulary knowledge, but the combination of the incidental and intentional learning instruction yields greater vocabulary gains; (b) only 91.8% of receptive vocabulary is understood productively; and (c) students' vocabulary size plays a decisive role in acquiring the receptive and productive aspect of vocabulary knowledge (150 words). Key words: Incidental learning, intentional learning, Receptive vocabulary, productive vocabulary, extensive reading
New types of armor, including space armor, multiple-layered armor, composite armor and modular armor have been successfully developed and installed on the armored vehicles of several nations. The protective capability of armor against penetration is established. Of developed composite armor, space armor has a simple structure and is easy to produce and can be produced at low cost. This study uses the finite element package DYTRAN and the pre and post processor PNTRAN to elucidate the ballistic resistance and penetration of space armor. Factors such as armor thickness, space between armors and projectile profile are considered. A technique for simulating the protection afforded by armor and supporting the design of space armor is developed.
Wireless sensor networks (WSNs) are formed by a great quantity of sensor nodes, which are consisted of battery-powered and some tiny devices. In WSN, both efficient energy management and Quality of Service (QoS) are important issues for some applications. Real-time services are usually employed to satisfy QoS requirements in critical environment. This paper proposes a real-time MAC (Medium Access Control) protocol with extended backoff scheme for wireless sensor networks. The basic idea of the proposed protocol employs (m,k)-firm constraint scheduling which is to adjust the contention window (CW) around the optimal value for decreasing the dynamic failure and reducing collisions DBP (Distant Based Priority). In the proposed protocol, the scheduling algorithm dynamically assigns uniform transmitting opportunities to each node. Numerical results reveal the effect of the proposed backoff mechanism.
In this study, sparsity maximization nonlinear blind deconvolution (NBD) is proposed to identify the vibration sources of satellite systems from mixed vibration signals. The proposed algorithm decomposes NBD into two independent stages, namely, nonlinear compensation and blind deconvolution. Since nonlinear distortion weakens the sparsity of the observed signals, sparsity maximization is introduced to the nonlinear compensation stage. In the blind deconvolution stage, the blind deconvolution algorithm with reference is used to separate the source signals. The proposed algorithm can improve the accuracy of source signal extraction from nonlinear mixed signals of complex mechanical systems. The effectiveness of the proposed method is verified through simulations. An experimental system of aluminum cabin structure is built based on the satellite's cabin structure. Results show that the proposed algorithm can successfully realize the identification of source signals.
There are limited research questioning the relationship between the disabled community and media, particularly in Malaysia. The lack of awareness and common assumption of specialty towards the disabled community have caused a small amount of local disability researches that question the relationship between the disabled community and the media. This research aims to find out the types of representation of disability in the Malaysian mainstream media, particularly press. Interview with visual disabled personnel and content analysis from news coverage of mainstream press are deployed in the study. The findings indicated the invalidity of disability culture as the misrepresentation of disabled community in Malaysia is not as severe as depicted by scholars because the news coverage focusing on them is getting more positive. Besides that, disabled people are not defensive towards the terms used to refer them as long as media practitioners do not over amplify their disability. The application of charity approach is still common in news coverage to portray the disabled community as victim, and therefore they are partially marginalized due to the misrepresentation in Malaysian mainstream press.
Previous research indicates that consumers may resist negative publicity when they perceive a firm to be socially responsible (Klein & Dawar, 2004; Chernev & Blair,2015). However, other research shows corporate social responsibility (CSR) may boomerang the damage of negative publicity (Sohn & Lariscy,2012). Firms may participate in CSR and it is important for market practitioners and researchers to understand the role of different types of CSR in minimizing the impact of negative publicity. This research aims to examine the moderating role of two types of CSR in the effect of negative publicity on consumer responses. An experiment with a 2 (negative publicity type: ability-related vs. morality-related) x 2 (CSR type: philanthropic donation vs. employee wellbeing) between-subjects factorial design was conducted in a major city of China. In the morality-related negative publicity and employee wellbeing condition, the participants were shown with employee wellbeing materials and a morality-related negatively publicized article about a fictitious hotel. Similar arrangements were setup for other different conditions. Then, consumer responses such as firm evaluation and patronage intention were measured. Results of two-way ANOVA revealed a significant interaction effect. The findings indicate that consumers' patronage intention is lower when a morality-related negative publicity has happened to a firm having “philanthropic donation” type of CSR, and also when an ability-related negative publicity has happened to a firm having “employee wellbeing” type of CSR.

As visual surveillance systems become more and more common in human lives, approaches based on these systems to solve security problems in practice are boosted, especially in railway applications. In this paper, we first propose a robust snag detection algorithm and then present a railway security system by using a combination of multiple sensors and the vision based snag detection algorithm. The system aims safety at several repeatedly occurred situations including slope protection, inspection of the falling-object from bridges, and the detection of snags and foreign objects on the rail. Experiments demonstrate that the snag detection is relatively robust and the system could guarantee the security of the railway through these real-time protections and detections.
