Self-disclosure in social networking sites
Authors: Cheung Christy , Lee Zach  W. Y. , Chan Tommy  K. H. 
Published: March 2015

Purpose
– The purpose of this paper is to examine the relative impacts of perceived cost, perceived benefits, and social influence on self-disclosure behaviors in social networking sites under an integrated theoretical framework.

Design/methodology/approach
– Building upon social exchange theory and privacy calculus theory, an integrated model was developed. The model was tested empirically using a sample of 405 social networking site’s users. Users were required to complete a survey regarding self-disclosure behaviors in Facebook.

Findings
– The results indicate that social influence is the factor which exhibits the strongest effect on self-disclosure in social networking sites, followed by perceived benefits. Surprisingly, perceived privacy risk does not have any significant impact on self-disclosure.

Research limitations/implications
– The results inform researchers about the importance to incorporate social influence factors and cultural factors into future online self-disclosure study.

Practical implications
– The results suggest that users focus on the benefits as well as social influence when they decide to reveal personal information in social networking sites, but pay less attention to the potential privacy risks. Educators are advised to launch educational programs to raise students’ awareness to the potential risks of self-disclosure in social networking sites. Service providers of social networking sites are encouraged to provide intuitive privacy indices showing users the levels of privacy protection.

Originality/value
– This paper is one of the first to develop and empirically tests an integrated model of self-disclosure in social networking sites.
A strategy-based model for implementing channel integration in e-commerce
Authors: Wu Ing-Long , Wu Shwu-Ming 
Published: March 2015

Purpose
– The key to success in the internet business lies in how you carry out the integration between virtual and physical channels. The purpose of this paper is to aim at defining the solution to the integration.

Design/methodology/approach
– Channel coordination is grounded on a new governance of integration strategy which bridges the channels. This study proposes a novel research model with three stages: first, click-and-brick strategies; second, channel coordination for three purchase stages; and third, synergy realizations. A survey was conducted for collecting empirical data. PLS was used for path analysis. In total, three separate statistical analyses were performed for three defined integration strategies.

Findings
– Click-and-brick strategies have different degrees of impact on channel coordination in different purchase stages and in turn, different degrees of impact on synergy benefits. Specifically, the in-house division strategy is more important in determining channel coordination in the three purchase stages.

Practical implications
– Customers initially perceive online services with a nature of low trust and view them as highly risky. This integration is useful for a firm to successfully start a new online business. Further, it provides insight into allocating a firm’s resources to critical multi-channel activities to realize synergy benefits.

Originality/value
– Multi-channel marketing is dynamic and complex in nature. Existing theories provide limited insight into effectively defining them. This study attempted to define a strategy-based implementation model. This model demonstrated the capability to effectively reduce the complexity of defining channel integration.
Measuring the effect of Chinese brand name syllable processing on consumer purchases
Authors: Pan Ming-Chuan , Kuo Chih-Ying , Pan Ching-Ti 
Published: March 2015

Purpose
– The purpose of this paper is to examine consumer reactions to product categories, online seller reputation, and brand name syllables.

Design/methodology/approach
– This paper uses four experimental designs to explore the seller reputation, product category, and brand name syllable effects in internet shopping. The authors chose sellers of (low/high) repute from Yahoo Mall. ANOVA is used to evaluate the results.

Findings
– Seller reputation moderates the effect of the brand name syllable level on purchase intention and product category moderates the effect of the brand name syllable level on purchase on internet (experiment 1). Consumers take the longest time to make purchasing decisions when buying credence goods or buying from sellers of low repute and that the response time mediates the moderating role of the product category (experiment 2) or reputation (experiment 3). Moreover, the effect of brand name syllable levels chosen/assigned by sellers of low repute is weakened for consumers with low (vs high) skepticism toward non-store shopping (experiment 4).

Practical implications
– This study is helpful to online sellers if they can identify their reputation, product category and those consumers have skepticism, they can create extra profit through brand name syllable practice.

Originality/value
– This paper extends the literature on consumers’ brand name syllable processing by identifying important moderators and probing into the decision process. The results allow us to substantiate prior research and suggest prescriptive strategies for internet retailers.
Contemporary diplomatics of the civil and deceased estate case files found at the national archives of Zimbabwe
Authors: Bhebhe Sindiso 
Published: March 2015

Purpose– This paper aims to discuss how the originality, authenticity, reliability and genuineness of legal records found at the National Archives of Zimbabwe (NAZ) are maintained. Provenance issues and their implications in diplomatics are also discussed. It notes that the status quo at the NAZ favours the diplomatic archiving of paper records, while electronic records are neglected.Design/methodology/approach– The paper uses a qualitative research approach. The data will mainly be collected using document analysis augmented by observations from the NAZ. Literature in regard to the Court Legal system of Zimbabwe will be reviewed and this even includes newspaper articles. Academic research papers on the archiving of electronic records in the less developed nations and developed nations will be reviewed also.Findings– The qualitative research approach revealed that the electronic national heritage of Zimbabwe is being lost mainly due to the archaic legislation which is silent on the management of electronic records. The results show again the violation of the sanctity of provenance principles in some selected cases. It was also found that the government is now producing both paper and electronic records, but the National Archives is only archiving paper records, the result of this being the incompleteness of records, thereby negatively affecting their diplomatics.Originality/value– Whereas a lot has been published about the management of electronic records in the developing world, this paper does not try to duplicate that but tries to bring a new dimension into this by showing how the diplomatics of these records is affected.
Stress-limiting test structures for rapid low-cost strength and stiffness assessment
Authors: Katz Andrew , Nussbaum Justin , Lusk Craig P , Crane Nathan B 
Published: March 2015

Purpose
– The purpose of this paper is to evaluate the use of a simple printed geometry to estimate mechanical properties (elastic modulus, yield strength) with inexpensive test equipment.

Design/methodology/approach
– Test geometry is presented that enables controlled strains with manual deformation and repeatable measurement of vibrational frequencies. This is tested with multiple fused deposition modeling (FDM) machines to assess measurement accuracy and repeatability. Printing orientation and some printing parameters are varied to assess the measurement sensitivity.

Findings
– The test methods show good correlation with manufacturer material specifications in the X-Y plane and reported elastic strain limits. It is also sensitive to printing orientation and printing parameters.

Research limitations/implications
– Further work is needed to assess the sensitivity of the method to particular defects and parameter errors expected in particular applications.

Originality/value
– This method supports process monitoring in production environments and inexpensive assessments of material properties for hobbyist and do-i- yourself users. While it is tested with FDM, it should be applicable to other additive manufacturing processes.
In vitro assessment of laser sintered bioactive glass scaffolds with different pore geometries
Authors: Kolan Krishna C R , Thomas Albin , Leu Ming C , Hilmas Greg 
Published: March 2015

Purpose
– The purpose of this paper is to utilize the selective laser sintering (SLS) process to fabricate scaffolds with complex pore shapes and investigate the effects of pore geometry in vitro. The pore geometry of scaffolds intended for use in bone repair is one of the most important parameters used to determine the rate of bone regeneration.

Design/methodology/approach
– Scaffolds with five different architectures, having approximately 50 per cent porosity, were fabricated with silicate (13–93) and borate (13–93B3)-based bioactive glasses using the SLS process. An established late-osteoblasts/early-osteocytes cell line was used to perform cell proliferation tests on the scaffolds. The cell-seeded scaffolds were incubated for two, four and six days followed by MTT assay to quantify the metabolically active cells.

Findings
– The results indicated that the cells proliferate significantly more on the scaffolds which mimic the trabecular bone architecture compared to traditional lattice structures. The surface roughness of the SLS-fabricated scaffolds drives the initial cell proliferation which is followed by curvature-driven cell proliferation.

Originality/value
– There have been very few studies on the effects of pore geometry on tissue growth and the existing reports do not provide clear indications. Instead of using bio-polymer or titanium-based scaffolds, we use bioactive glass scaffolds. The results obtained from this study add to the understanding of the effect of pore geometry on cell proliferation, which is based on the experimental data and analysis of the scaffolds’ surface curvature.
Experimental-assisted design development for an octahedral cellular structure using additive manufacturing
Authors: Yang Li 
Published: March 2015

Purpose
– This paper aims to demonstrate the design and verification of a 3D reticulate octahedral cellular structure using both analytical modeling and additive manufacturing. Traditionally, it has been difficult to develop and verify designs for 3D cellular structures due to their design complexity.

Design/methodology/approach
– Unit cell modeling approach was used to model the octahedral cellular structure. By applying structural symmetry simplification, the cellular structure was simplified into a representative geometry that could be further designed with a standard beam theory. The verification samples were fabricated with EBM process using Ti6Al4V as materials, and compressive testing were performed to evaluate their properties. In addition, designs with different number of unit cells were investigated to evaluate their size effect.

Findings
– Explicit mechanical property design (including modulus and compressive strength) of the octahedral cellular structure was realized via parametric equations driven by geometrical designs and material types. In addition, it was verified both numerically and experimentally that the octahedral cellular structure exhibit unusual size effect, which is highly predictable. Unlike some of the other cellular structures, the octahedral cellular structure exhibits softening behavior when the number of unit cell increases between the sandwich skins, which could be explained by the upsetting effect commonly observed in bulk deformation processes.

Originality/value
– This paper established a more comprehensive understanding in the design of octahedral cellular structures, which could enable this type of structure to be designed for sandwich structures with higher fidelity. Therefore, this study not only demonstrated an efficient methodology to design 3D cellular structures using additive manufacturing, but also facilitated the development of design for an additive manufacturing theory.
An exploration of binder jetting of copper
Authors: Bai Yun , Williams Christopher B 
Published: March 2015

Purpose
– The purpose of this paper is to explore the use of binder jetting to fabricate high-purity copper parts. The ability to fabricate geometrically complex copper shapes would have implications on the design and manufacture of components for thermal management systems and structural electronics.

Design/methodology/approach
– To explore the feasibility of processing copper via binder jetting, the authors followed an established material development process that encompasses powder selection and tuning process parameters in printing and thermal cycles. Specifically, the authors varied powder size and sintering cycles to explore their effects on densification.

Findings
– Three differently sized copper powders were successfully printed, followed by sintering in a reducing atmosphere. It was found that a 15-μm-diameter powder with a sintering cycle featuring a 1,080°C maximum temperature provides the most dense (85 per cent) and pure (97 per cent) final copper parts of the parameters tested.

Research limitations/implications
– Due to powder-based additive manufacturing techniques’ inherent limitations in powder packing and particle size diameter, there are difficulties in creating fully dense copper parts. To improve thermal, electrical and mechanical properties, future work will focus on improving densification.

Originality/value
– The paper demonstrates the first use of binder jetting to fabricate copper artifacts. The resulting copper parts are denser than what is typically found in binder jetting of metal powders (without infiltration); significant opportunity remains to further optimize the manufacturing process by introducing novel techniques to tailor the material properties for thermal/electrical applications.
Design and performance evaluation of a 3-axis force sensor for MIS palpation
Authors: Li Kun , Pan Bo , Zhan Juncheng , Gao Wenpeng , Fu Yili , Wang Shuguo 
Published: March 2015

Purpose
– This paper aims to develop a novel miniature 3-axis force sensor which can detect the interaction forces during tissue palpation in MIS (minimally invasive surgery). MIS offers many significant merits compared with traditional open surgery, the wound to the patients and the postoperative pains are alleviated and reduced dramatically. However, the inherent drawback due to lack of force feedback still exists while conducting some operation procedures. For example, tissue palpation performed easily during open surgery could not be realized in an MIS manner.

Design/methodology/approach
– The force sensor is based on the resistive-based sensing method that utilizes strain gauges to measure the strain when the external loads are acting on the tip of the sensor. A novel flexible tripod structure with bending and compression deformations is designed to discriminate the magnitudes and directions of the three orthogonal force components. A linear characteristic matrix is derived to disclose the relationship between the sensitivity and the geometric parameters of the structure, and a straightforward geometric parameterized optimization method considering the sensitivity isotropy is proposed to provide the sensor structure with high sensitivity and adequate stiffness.

Findings
– The sensor prototype can perform force measurement with sensing ranges of ± 3.0 N in axial direction and ± 1.5 N in radial direction, and the resolutions are 5 per cent and 1 per cent, respectively. It is concluded that this force sensor is compatible with MIS instruments and the ex-vivo experiment shows that the sensor can be used to perform tissue palpation during MIS procedures.

Originality/value
– This paper is intended to address the significant role of force sensing and force feedback during MIS operations, and presents a new application of the resistive-based sensing method in MIS. A tripod structure is designed and a straightforward optimization method considering the sensitivity isotropy of the sensor is proposed to determine geometric parameters suited for the given external loads.
Wireless measurement for passive pressure sensors in high temperature environment
Authors: Hong Yingping , Liang Ting , Jia Pinggang , Liu Wenyi , Tan Qiulin , Li Chen , Zheng Tingli , Ge Binger , Xiong Jijun 
Published: March 2015

Purpose
– Physical contact and traditional sensitive structure Physical contact and traditional pressure-sensitive structures typically do not operate well in harsh environments. This paper proposes a high-temperature pressure measurement system for wireless passive pressure sensors on the basis of inductively coupled LC resonant circuits.

Design/methodology/approach
– This paper begins with a general introduction to the high-temperature pressure measurement system, which consists of a reader antenna inductively coupled to the sensor circuit, a readout unit and a heat insulation unit. The design and fabrication of the proposed measurement system are then described in detail.

Findings
– A wireless passive pressure sensor without an air channel is fabricated using high-temperature co-fired ceramics (HTCC) technology and its signal is measured by the designed measurement system. The designed heat insulation unit keeps the reader antenna in a safe environment of 159.5°C when the passive sensor is located in a 900°C high-temperature zone continuously for 0.5 h. The proposed system can effectively detect the sensor’s resonance frequency variation in a high bandwidth from 1 to 100 MHz with a frequency resolution of 0.006 MHz, tested from room temperature to 500°C for 30 min.

Originality/value
– Expensive and bulky equipment (impedance analyzers or network analyzers) restrict the use of the readout method outside the laboratory environment. This paper shows that a novel readout circuit can replace the laboratory equipment to demodulate the measured pressure by extracting the various sensors’ resonant frequency. The proposed measurement system realizes automatic and continuous pressure monitoring in a high-temperature environment with a coupled distance of 2.5 cm. The research finding is meaningful for the measurement of passive pressure sensors under a wide temperature range.

Authors: Sang Shengbo , Zhai Ruiyong , Zhang Wendong , Sun Qirui , Zhou Zhaoying 
Published: March 2015

Purpose
– This study aims to design a new low-cost localization platform for estimating the location and orientation of a pedestrian in a building. The micro-electro-mechanical systems (MEMS) sensor error compensation and the algorithm were improved to realize the localization and altitude accuracy.

Design/methodology/approach
– The platform hardware was designed with common low-performance and inexpensive MEMS sensors, and with a barometric altimeter employed to augment altitude measurement. The inertial navigation system (INS) – extended Kalman filter (EKF) – zero-velocity updating (ZUPT) (INS-EKF-ZUPT [IEZ])-extended methods and pedestrian dead reckoning (PDR) (IEZ + PDR) algorithm were modified and improved with altitude determined by acceleration integration height and pressure altitude. The “AND” logic with acceleration and angular rate data were presented to update the stance phases.

Findings
– The new platform was tested in real three-dimensional (3D) in-building scenarios, achieved with position errors below 0.5 m for 50-m-long route in corridor and below 0.1 m on stairs. The algorithm is robust enough for both the walking motion and the fast dynamic motion.

Originality/value
– The paper presents a new self-developed, integrated platform. The IEZ-extended methods, the modified PDR (IEZ + PDR) algorithm and “AND” logic with acceleration and angular rate data can improve the high localization and altitude accuracy. It is a great support for the increasing 3D location demand in indoor cases for universal application with ordinary sensors.

Design/methodology/approach
– This paper presents a low-power multiple physiological parameters monitoring system (MPMS) which comprises four subsystems. These are: electrocardiogram (ECG)/respiration (RESP) parameters monitoring subsystem with embedded algorithms; blood oxygen (SpO2)/pulse rate (PR)/body temperature (BT)/blood pressure (BP) parameters monitoring subsystem with embedded algorithms; main control subsystem which is in charge of system-level power management, communication and interaction design; and upper computer software subsystem which manipulates system function and analyzes data.

Findings

Originality/value
– First, a power reduction technique at the physical/hardware level is designed to realize low power consumption. Second, the proposed MPMS device enables simultaneously monitoring six key parameters. Third, unlike most monitoring systems in bulk size, the proposed system is much smaller (118 × 58 × 18.5 mm3, 140 g total weight). In addition, a comfortable smart shirt is fabricated to accommodate the portable device, offering reliable measurements.
