Leadership for future libraries
Authors: O'Connor Steve 
Published: August 2014

Purpose
– Leadership is always important but is especially important at times of rapid and even fundamental change. The purpose of this paper is to discuss and evidence the changes and decisions facing librarians in our world against the backdrop of international disrupted business models for libraries. The traditional mode of operation for libraries is changing dramatically in order to stay relevant and connected to our library users. This paper will aim to explore future leadership styles which will be required for special librarians. This will be set in the context of the NextGen Leadership program which this author established and conducted across Hong Kong, Singapore and Shanghai. The paper will also seek to draw on the author's experiences seeking new scenario futures for special libraries in Australia.

Design/methodology/approach
– This paper will explore future leadership styles which will be required for special librarians. This will be set in the context of the NextGen Leadership program which this author established and conducted across Hong Kong, Singapore and Shanghai. It will also draw on the author's experiences seeking new scenario futures for special libraries in Australia.

Findings
– The evaluation of the Next Gen Leadership program is reviewed in this paper.

Research limitations/implications
– The implications are that librarians need programs such as Next Gen in order to be able to test new ways of adopting management behaviours. These new ways of operating can be tested through programs such as Next Gen which operate over a lengthy period of time.

Practical implications
– It is crucial that existing managers of academic libraries establish these leadership programs into the future as a means of ensuring good succession planning.

Originality/value
– This is a genuinely original program spanning three countries/cities; Hong Kong, Singapore and Shanghai. The opportunity for participants in this course to meet, inter-mingle and network into the future with similar colleagues is unique. The opportunities to test new modes of management in such a course, remote from the work environment, are of value to the management styles of each individual into the future.

Authors: Ren Xiaoai 
Published: August 2014

Purpose
– The purpose of this paper is to look at the organizational structure and service provisions of cooperative public library systems in New York State. The study also seeks to ask questions of how cooperative public library systems decide what services to provide.

Design/methodology/approach
– Descriptive statistics, factor analysis and cluster analysis were applied on New York State public library systems’ 2008 annual reports to generate quantitative profiles of public library systems and their service transactions. Three cooperative public library systems displaying different service features were purposefully selected for further study of their service decision-making processes. The face-to-face and phone interviews were adopted in the study.

Findings
– Research findings from this study provide information on specific service variations across cooperative public library systems. The findings also provide differences of service decision-making processes in addition to the factors that might cause these differences.

Originality/value
– This study adds knowledge of public library systems’ management and organizational structures, therefore fills a knowledge gap on public library systems. It can also serve as the baseline for future studies using newer annual report data and therefore to study the changing roles and services of cooperative public library systems in New York State.

Authors: Ka Wai Wong Gabrielle 
Published: August 2014

Purpose
– The purpose of this paper is to describe how the Hong Kong University of Science and Technology (HKUST) Library collected a rich set of assessment data for its Learning Commons (LC), and how it analyzed, summarized and presented the data to drive improvement as well as to demonstrate impact.

Design/methodology/approach
– The assessment targeted at exploring users’ perception of and experience in using the LCs. It employed multiple channels to collect data. It comprised of three student focus groups, and two questionnaire surveys for students and service partners, respectively. They were planned strategically, with clear objectives and a phase-by-phase design, so that the instruments can be fine-tuned based on the findings and experience of the previous one.

Findings
– The assessment collected a good amount of qualitative and quantitative data. It showed that the LCs had become a very important part of students’ campus life. Students’ experience reported through the focus groups and survey helped the Library to make a number of improvement in services and facilities. The result was tactfully presented to senior university administrators as a proof of the Library's impact.

Practical implications
– The case study showed how an assessment, when strategically planned, can generate findings that help libraries to demonstrate their capability and impact on students’ academic life. The methods applied in this case study can also be used by other functional areas.

Originality/value
– The assessment went beyond quantitative measures, it tapped into students’ experience. The paper illustrates how HKUST Library analyzed and presented the data to achieve results and changes. Other libraries may find this process helpful for future assessment planning.

Authors: Arazna Aneta , Kozioł Grażyna , Futera Konrad , Janeczek Kamil , Lipiec Krzysztof 
Published: August 2014

Purpose
– The purpose of this paper was to determine the influence of thermal aging on the stability of organic light-emitting diode (OLED) glass samples made in ambient condition.

Design/methodology/approach
– The samples with yellow emitting layer (named as ADS5) and poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) hole transport layer were examined. Some of the devices were ultraviolet-curable epoxy encapsulation directly after performance. All samples were thermally annealed at 70°C for 1, 2, 3 and 4 hours. The characteristics current–voltage for fresh and aging samples in the range of voltage from 0-15 V were made. The temperature of OLEDs samples in real-time with a thermographic camera was measured too. Additionally, scanning electron microscope image of surface Al cathode immediately after OLED performance and after annealing tests was made.

Findings
– The authors stated, that irrespective of the type, the samples were undergoing the degradation. The decrease in value of the current density was registered. That were about 44 per cent and about 24 per cent after thermally annealing the samples with and without encapsulation, respectively (at tension 13 V). Additionally, there were observed massive delamination of the metal cathode.

Originality/value
– Influence of thermal annealing and encapsulation on the dynamic characteristics of the OLED devices fabricated in ambient condition was analyzed. There are not many papers in the literature describing examinations of OLED samples which were made in environmental conditions.

Authors: Dabrowski Arkadiusz , Elkjaer Karl , Borregaard Louise , Zawada Tomasz , Golonka Leszek 
Published: August 2014

Purpose
– The purpose of this paper is to develop the device made of low temperature co-fired ceramics (LTCC) and lead zirconate titanate (PZT) by co-firing both materials. In the paper, the technology and properties of a miniature uniaxial ceramic accelerometer are presented.

Design/methodology/approach
– Finite element method (FEM) is applied to predict properties of the sensor vs main dimensions of the sensor. The LTCC process is applied during manufacturing of the device. All the advantages of the technology are taken into account during designing three-dimensional structure of the sensor. The sensitivity and resonant frequency of the accelerometer are measured. Real material parameters of PZT are estimated according to measurement results and FEM simulations.

Findings
– The ceramic sensor integrated with SMD package with outer dimensions of 5 × 5 × 5 mm3 is manufactured. The accelerometer exhibits sensitivity of 0.75 pC/g measured at 100 Hz. The resonant frequency is equal to about 2 kHz. Useful frequency range is limited by 3 dB sensitivity change at about 1 kHz.

Research limitations/implications
– Sensitivity of the device is limited by interaction between LTCC and PZT materials during co-firing process. The estimated d parameters are ten times worse comparing to bulk Pz27 material. Further research on materials compatibility should be carried out.

Practical implications
– The sensor can be easily integrated into various devices made of standard electronic printed circuit boards (PCBs). Applied method of direct integration of piezoelectric transducers with LTCC material enables manufacturing of complex ceramic systems with built-in accelerometer in the substrate.

Originality/value
– The accelerometer is a sensor and a package simultaneously. The miniature ceramic device is compatible with surface mounting technology; hence, it can be used directly on PCBs for vibration monitoring inside electronic devices and systems.
Influence of firing process quality on dielectric constant of microwave LTCC substrates
Authors: Barteczka Beata , Slobodzian Piotr , Dabrowski Arkadiusz , Golonka Leszek 
Published: August 2014

Purpose
– The purpose of this paper was to investigate the influence of non-uniform temperature distribution inside a box furnace during the firing process on electrical properties of the low-temperature co-fired ceramic (LTCC) materials used in radio frequency (RF)/microwave applications.

Design/methodology/approach
– The authors studied the change in dielectric constant of two popular LTCC materials (DP 951 and DP 9K7) depending on the position of their samples inside the box furnace. Before firing of the samples, temperature distribution inside the box furnace was determined. The dielectric constant was measured using the method of two microstrip lines.

Findings
– The findings showed that non-uniform temperature distribution with spatial difference of 6°C can result in 3-4 per cent change of the dielectric constant. It was also found that dielectric constant of the two tested materials shows disparate behavior under the same temperature distribution inside the box furnace.

Practical implications
– The dielectric constant of the substrate materials is crucial for RF/microwave applications. Therefore, it was shown that 3-4 per cent deviation in dielectric constant can result in considerable detuning of microwave circuits and antennas.

Originality/value
– To the best of the authors’ knowledge, the quantitative description of the impact of temperature distribution inside a box furnace on electrical properties of the LTCC materials has never been published in the open literature. The findings should be helpful when optimizing production process for high yield of reliable LTCC components like filters, baluns and chip antennas.
Measurements of thermal resistance of power LEDs
Authors: Górecki Krzysztof 
Published: August 2014

Purpose
– The purpose of this paper is to present a new method of measuring thermal resistance of power light-emitting diodes (LEDs). Properties of power LEDs strongly depend on their internal temperature. The value of this temperature depends on the cooling conditions characterized by thermal resistance.

Design/methodology/approach
– The new method of measuring the value of this parameter belongs to the group of electric methods. In this method, the problem of estimating the value of electrical power converted into light is solved. By comparing the values of the case temperature obtained for the LED operating in the forward mode and the reverse-breakdown mode, the thermal power is estimated. On the basis of the measured value of the thermally sensitive parameter (the LED forward voltage) and the estimated value of the thermal power, thermal resistance is calculated.

Findings
– The elaborated method was used to measure thermal resistance of the selected types of power LEDs operating at different cooling conditions. The correctness of the elaborated measurement method was proved by comparing the results of measurements obtained with the use of the new method and the infrared method.

Research limitations/implications
– On the basis of the obtained results of measurements and the catalog data of the tested diodes, the dependence of the measurement error of thermal resistance of the LED on its luminous efficiency is discussed.

Originality/value
– The new measurement method is easy to use and more accurate than the classical method of thermal resistance measurement of the diode.

Authors: Gupta Agam , Mateen Arqum 
Published: August 2014

Purpose
– The purpose of this paper is to conceptualize a model for sponsored search advertising by incorporating a number of factors which affect the performance of these ads.

Practical implications
– This work is derived primarily from practice. It is hope that after due empirical validation, advertisers, users as well as search engines will benefit from this stream of research.

Originality/value
– This is one of the first works to analyze a sponsored search ad at a micro level. It brings into focus one of the largely unexplored facets of sponsored search advertising.
Temperature stress for bending beam with different moduli under different constraints
Authors: Yao Wenjuan , Liu Jiankang 
Published: August 2014

Purpose
– The purpose of this paper is to solve temperature stress for bending beam with different moduli under different constraints subject to nonlinear temperature.

Design/methodology/approach
– The equations of neutral axis position, normal stress, and displacement of bending beam with different moduli subjected to nonlinear temperature were derived based on different moduli elasticity theory. Meanwhile, iterative procedure was programmed to solve the nonlinear equations. The analytical solution can return back into the result of the same modulus theory, and the analytical solution was compared with finite element numerical solution. It shows that the analytical model proposed in this paper is reliable to use. Furthermore, the influence of different moduli characteristics on the temperature stress and deformation is discussed.

Findings
– The mechanical behavior of the bending beam with different moduli subject to nonlinear temperature is quite different from the one that is subjected to force. The bending beam maybe exist two neutral axis, and the reasonable selection of tension modulus and compression modulus can improve the distribution of the normal stress and reduce the maximum tensile stress or the maximum compressive stress.

Originality/value
– The crack produced by temperature stress will affect the integrity and the durability of the structure. The solution for temperature problem with different moduli theory is rarely reported at home and board. In view of this, this paper will do some exploratory research-temperature stress for bending beam with different moduli.

Authors: Qin Song Ya , I.A. Othman Mohamed , Zhao Zheng 
Published: August 2014

Purpose– The purpose of this paper is to study the reflection of a plane harmonic wave at the interface of thermo-microstretch elastic half space. The modulus of elasticity is taken as a linear function of reference temperature. The formulation is applied to generalized thermoelasticity theories, the Lord-Shulman and Green-Lindsay theories, as well as the classical dynamical coupled theory. Using potential function, the governing equations reduce to ten-order differential equation.Design/methodology/approach– Coefficient ratios of reflection of different waves with the angle of incidence are obtained using continuous boundary conditions. By numerical calculations, the variation of coefficient ratios of reflection with the angle of incidence is illustrated graphically for magnesium crystal micropolar material under three theories.Findings– The effect of different temperature-dependent constants and frequency on the coefficient ratios of reflection is illustrated graphically in context of Lord-Shulman theory.Originality/value– The reflection coefficient ratios are given analytically and illustrated graphically. The effects of thermal relaxation times are very small on reflection coefficient ratio. The temperature-dependent constant and wave frequency have a strong effect on the reflection coefficient ratios.
Curing behaviour and mechanical properties of pigmented UV-curable epoxy acrylate coatings
Authors: Kardar Pooneh , Ebrahimi Morteza , Bastani Saeed 
Published: August 2014

Purpose
– The purpose of this work was to study the effect of chemical structure of reactive diluents on the curing behaviour and physical–mechanical properties of a titanium dioxide pigmented UV-curable epoxy acrylate system.

Design/methodology/approach
– Two different tri-functional and two different tetra-functional acrylate monomers were used as reactive diluents in the formulations. The curing behaviour of the formulations was studied by using photo-differential scanning calorimetry analysis. The rate of curing, conversion at the maximum rate and ultimate conversion for different formulations were calculated. In addition, the physical and mechanical characteristics of the cured films, including glass transition temperature and modulus, were measured by using a dynamic mechanical analysis technique.

Findings
– The results showed that the ultimate conversion for non-pigmented pentaerythritol triacrylate (PETA) and trimethylol propane triacrylate (TMPTA) formulations were almost similar, but the interference effect of titanium dioxide particles on the curing of the PETA formulations was found to be more considerable in comparison to the TMPTA formulations. The extent of reaction for tetra-functional acrylate monomers was considerably less than those for tri-functional acrylate monomers. The Tg and storage modulus of non-pigmented PETA, TMPTA and pentaerythritol tetraacrylate (PE4TA) formulations were almost the same and higher than that for ditrimethylol propane tetraacrylate (DiTMP4TA) formulations. However, Tg and storage modulus of pigmented tetra-functional acrylate monomer formulations were higher than those for tri-acrylate monomer formulations.

Research limitations/implications
– The curing conditions (temperature and UV intensity) can affect the network formation and consequently will affect on the properties of the cured films.

Practical implications
– The pigmented UV-curable coatings are interested for many industries such as wood and automotive industries. The reported data can be used by the formulators working in the R&D departments. In addition, the results obtained can be used by the researchers who are active in the field of structure–property relationship for UV-curable coatings.

Social implications
– UV-curing systems are considered as one of the most environment-friendly coatings system. Therefore, the developing of its knowledge can help to extend its usage to different applications.

Originality/value
– The photopolymerisation of pigmented coatings is a great challenge and is hardly investigated in the literature. Therefore, in this research, the effect of chemical structure and functionality of different multifunctional acrylate monomers on the curing behaviour of pigmented formulations was investigated.
