Path analysis for proposed framework of SCM excellence in Indian manufacturing industry
Authors: Soni Gunjan , Kodali Rambabu 
Published: May 2016

Purpose
– Several authors in extant literature have shown concern towards lacuna in availability of standard constructs in supply chain management (SCM). These standard constructs can represent pillars of SCM excellence. However, frameworks on SCM excellence unlike its contemporary fields are very few. Thus the purpose of this paper is to develop a path analysis for proposed framework of SCM excellence in Indian manufacturing industry proposed by Soni and Kodali (2014) using interpretive structural modelling (ISM) and structural equation modelling (SEM).

Design/methodology/approach
– The ISM is performed on two exemplary cases of supply chain in Indian manufacturing industry. These cases were selected on the consideration of supply chain excellence index (SCEI), based on the results of an empirical study conducted by Soni and Kodali (2014) in Indian manufacturing industry. The focal manufacturing company which exhibited lowest and highest SCEI were selected as contenders for developing ISM. The relationships among pillars and constructs of SCM excellence framework are obtained from ISM, and later are subjected to statistical testing of model fit by using SEM. The input to SEM was the respondent’s data used in previous study.

Findings
– The major findings revealed that ISM based on focal company having highest SCEI, is statistically fit for SCM excellence framework, and finally the structural models of the constructs for each pillar of SCM excellence are also formed by using path analysis.

Originality/value
– The study offers a unique managerial approach for analysing the underlying relationships between pillars of SCM excellence. Researchers can use this study for developing frameworks in various realms of SCM excellence.

Purpose
– The purpose of this paper is to propose a new assessment tool for Leagility.

Design/methodology/approach
– This research was carried out to systematically propose the operational activities of Leagile supply chains (SCs) with regard to SC drivers. Particularly, SC logistic (facility, transportation and inventory) and cross-functional drivers (information, sourcing and pricing) were selected to classify all operational activities of Leagile SCs.

Findings
– This study proposed a new framework to evaluate the operational activities of Leagile SCs. Operational activities of Leagile supply chain strategy were determined and categorized with regard to SC drivers. These activities were ranked using an analytic hierarchy process and were then categorized using a cycle view of SC.

Originality/value
– This study contributed in proposing operational activities of Leagile SC based on its major drivers. The result of this study assist managers, scholars and practitioners to construct new Leagile SCs or assess their Leagility level.
Does good corporate governance enhance accruals quality during financial crises?
Authors: Aldamen Husam , Duncan Keith 
Published: May 2016

PurposeThe purpose of this study is to examine the efficacy of corporate governance systems in enhancing earnings quality during the recent global financial crisis (GFC). The literature provides insight into the corporate governance–accruals quality relationship during periods of relative financial stability. However, little is known about periods of unexpected financial shocks such as the GFC.Design/methodology/approachThe sample consists of 340 companies (1,020 firm years) listed on the ASX during 2007-2009. Factor analysis is used to compute corporate governance factors. Seemingly unrelated regression (SUR) is used to test the impact of pre-GFC corporate governance on accruals quality during the GFC.FindingsConsistent with prior research, the findings suggest that good corporate governance is positively related to accruals quality before the GFC. More importantly, the impact of good governance intensifies during the GFC, where the mitigating role of governance is arguably under pressure. Furthermore, during the GFC, good corporate governance also affects the level of asset impairment.Research limitations/implicationsThe study provides empirical evidence that the relationship between good corporate governance practices and accruals quality is amplified during the GFC. The results support the efforts of market regulators to improve the governance of companies and make them stronger during financial crises.Originality/valueThe study is an important addition to corporate governance research because it tests governance dynamics in a unique crisis period and establishes that corporate governance structures are effective when most needed.
BiCMOS Colpitts oscillator for vector-sum interpolators
Authors: George Deepa , Sinha Saurabh 
Published: May 2016

Purpose
The demand for higher bandwidth has resulted in the development of mm-wave phased array systems. This paper aims to explore a technique that could be used to feed the individual antennas in a mm-wave phased array system with the appropriate phase shifted signal to achieve the required directivity. It presents differential Colpitts oscillators at 5 and 60 GHz that can provide differential output signals to the quadrature signal generators in the proposed phase shifter system.

Design/methodology/approach
The phase shifter system comprises a differential Colpitts voltage controlled oscillator (VCO) and utilizes the vector-sum technique to generate the phase shifted signal. The differential VCO is connected in the common-collector configuration for the 5-GHz VCO, and is extended using a cascode transistor for the 60-GHz VCO for better stability at mm-wave. The vector sum is achieved using a variable gain amplifier (VGA) that combines the in-phase and quadrature phase signal, generated from oscillator output using hybrid Lange couplers. The devices were fabricated using IBM 130-nm SiGe BiCMOS process, and simulations were performed with a process design kit provided by the foundry.

Findings
The measured results of the 5-GHz and 60-GHz VCOs indicate that differential Colpitts VCO could generate oscillator output with good phase noise performance. The simulation results of the phase shifter system indicate that the generation of signals with phases from 0° to 360° in steps of 22.5° was achieved using the proposed approach. A Gilbert mixer topology was used for the VGA and the linearity was improved by a pre-distortion circuit implemented using an inverse tanh cell.

Originality/value
The measurement results indicate that differential Colpitts oscillator in common-collector configuration could be used to generate differential VCO signals for the vector-sum phase shifter. The simulation results of the proposed phase shifter system at mm-wave show that the phase shift could be realised at a total power consumption of 200 mW.

Authors: Rafiee Peyman , Khatibi Golta , Solazzi Francesco 
Published: May 2016

Purpose
The purpose of this study is to address the nonlinear oscillations of single-crystal silicon micro-electromechanical systems (MEMS) accelerometers subjected to mechanical excitation.

Methodology/approach
The nonlinear behavior was detected and analyzed by using experimental, analytical and numerical approaches. Piezoelectric shaker as a source of mechanical excitation and differential laser Doppler vibrometer in combination with a micro system analyzer were used in the experimental effort. Two types of devices considered included nonencapsulated samples and samples encapsulated in nitrogen gas compressed between two glasses. Numerical and analytical investigations were conducted to analyze the nonlinear response. A novel method has been suggested to calculate the nonlinear parameters. The obtained experimental, numerical and analytical results are in good agreement.

Findings
It has been found that the nonlinearity leads to a shift in frequencies and generates higher harmonics, but, most importantly, reveals new phenomena, such as the jump and instability of the vibration amplitudes and phases.

Originality/value
It has been shown that under the constant excitation force, the MEMS device can work in both linear and nonlinear regions. The role of the beat phenomenon has been also addressed and discussed. It has been found that the attributes of the nonlinear response are strongly dependent on the level and duration of the excitation. It is concluded that the nonlinear response of the systems is strongly dependent on the level of the excitation energy. It has been also concluded that larger quality factors are able to enhance dramatically the nonlinear effects and vice versa.

Published: May 2016

Purpose
This paper aims to purpose the new design and fabrication scheme of Touch Mode Capacitive Pressure Sensor (TMCPS), which can be used in a wireless integrated resistor, inductor and capacitor circuit for monitoring pressure in biomedical applications.

Design/methodology/approach
This study focuses on the design, simulation and fabrication of dynamic capacitors, based on surface micromachining using polysilicon or aluminum films as the top electrode, both structural materials are capped with a 1.5 μm-thick polyimide film.

Findings
The design of microstructures using a composite model fits perfectly the preset mechanical behavior. After the full fabrication, the dynamic capacitors show complete mechanical flexibility and stability.

Originality/value
The novelty of the method presented in this study includes two important aspects: first, the capacitors are designed as a planar cavity within a rigid frame, where two walls contain channels which allow for the etching of the sacrificial material. Second, the electromechanical structures are designed using a composite model that includes a polyimide film capping for a precise pressure sensing, which also protects the internal cavity and, at the same time, provides full biocompatibility.
Computer classes for older people: motivations and outcomes
Authors: Zaidman Sebastian , Tinker Anthea 
Published: May 2016

Purpose
– A “digital divide” exists between older and younger people in terms of computer use and older people’s uptake of computer training programmes in the UK remains low. The purpose of this paper is to identify the motivations and outcomes of computer classes for some older people and the contributory factors.

Design/methodology/approach
– One-to-one qualitative semi-structured interviews were conducted with eight participants at a computer class in a London community centre. Using a topic guide, interview transcripts underwent thematic analysis. The theoretical perspective of “ageing in place” (the ability to stay in one’s own home in later life) was used when interpreting the findings.

Findings
– Participants had been motivated to attend the class initially to gain computer skills. Initial motivation was influenced by the death of a spouse and the desire to remain mentally active. The main outcome by the class was acquisition of computer skills. Psychological and social benefits were also reported, the latter constituting motivation for continued attendance. Computer ownership and gender differences in preferred teaching style influenced class outcomes.

Research limitations/implications
– Although this was a small sample comprising older people solely from one community, participant backgrounds varied and the findings suggest that further research with a larger, more culturally heterogeneous sample would be valuable.

Originality/value
– Computer classes benefit older people wishing to learn computer skills which may facilitate “ageing in place”. There has been little research in this area.

Rapid and simple identification of Beijing genotype strain of Mycobacterium tuberculosis using a loop‐mediated isothermal amplification assay
Authors: Nagai Yuhki , Iwade Yoshito , Nakano Manabu , Akachi Shigehiro , Kobayashi Takashi , Nishinaka Takamichi 
Published: May 2016

ABSTRACTBeijing genotype strains of Mycobacterium tuberculosis are geographically widespread and pose a notorious public health problem, these strains causing outbreaks of multidrug‐resistant tuberculosis (TB); some studies have reported an association with drug resistance. Because the prevalence of Beijing strain has a substantial impact on TB control programs, the availability of a rapid and reliable method for detecting these strains is important for epidemiological monitoring of their circulation. The main methods currently used to identify Beijing genotype strains are IS6110 DNA fingerprinting, spoligotyping and PCR to detect specific deletions such as region of difference (RD)207. More recently, multiplex PCR assay using a Beijing‐specific single nucleotide polymorphism (SNP) has been developed for detecting Beijing lineage strains. However, these methods are time‐consuming and technically demanding. In the present study, a loop‐mediated isothermal amplification (LAMP) assay that allows specific identification of Beijing genotype strain was developed. This Beijing genotype strain‐identifying LAMP assay was performed 214 clinical isolates and the results compared with those of conventional PCR that targeted RD207 and Rv0679c‐targreting multiplex PCR for Beijing lineage identification. LAMP assay showed 100% sensitivity and specificity compared with RD207‐PCR. Furthermore, the sensitivity and specificity were 99.3% and 100%, respectively, compared with Rv0679c‐multiplex PCR. This LAMP assay could be used routinely in local laboratories to monitor the prevalence of the Beijing genotype strain and thereby used to help control the spread of these potentially highly virulent and drug resistant strains.
Searching for prey in a three‐dimensional environment: hierarchical movements enhance foraging success in northern elephant seals
Authors: Adachi Taiki , Costa Daniel P. , Robinson Patrick W. , Peterson Sarah H. , Yamamichi Masato , Naito Yasuhiko , Takahashi Akinori 
Published: May 2016

Summary

Foraging theory predicts that predators adjust their movements according to the spatial distribution of prey. Since prey is often patchily distributed, area‐restricted search (ARS) behaviour, characterized by sinuous search paths of predators with increased turning frequency, should be effective in foraging.

However, it remains unclear whether ARS behaviour actually enhances foraging success in free‐ranging animals, especially in marine animals that forage in a three‐dimensional (3D) environment.

Here, we reconstructed 3D dive paths of a highly pelagic marine predator, the northern elephant seal (n = 3), with multisensor data loggers that recorded depth, tri‐axis acceleration, tri‐axis magnetism and swim speed. We identified spatial scales of volume‐restricted search (VRS, termed for 3D ARS) behaviour using spherical first‐passage time analysis on 3D dive paths, accompanied with quantifying feeding rates in VRS by using mandible accelerometers that recorded feeding events.

Seals exhibited VRS behaviour at two spatial scales (radius of spheres): small‐VRS (8–10 m) and large‐VRS (17–19 m). Most feeding events occurred in VRS zones (78 and 86% for small and large‐VRS, respectively), although VRS accounted for a small proportion of bottom phase of dives in distance travelled. This suggests a strong link between VRS behaviour and foraging success.

There was a hierarchical structure to the VRS; most small‐VRS (95%) were nested within large‐VRS (i.e. nested VRS). Importantly, nested VRS had significantly higher feeding rates than non‐nested VRS, because nested VRS contained small‐ and large‐VRS with higher and lower feeding rates, respectively. These results suggest that seals forage on mesopelagic prey in a hierarchical patch system where high‐density patches at small scales are nested within low‐density patches at larger scales.

We demonstrated that seals employed scale‐dependent, hierarchical 3D movements and that underwater fine‐scale sinuous movements (i.e. VRS) were strongly linked to higher foraging success, particularly within nested VRS zones. We suggest that seals enhanced foraging success by employing hierarchical movements that possibly reflect the hierarchical property of prey distribution. Although recent studies advocate that optimal searching behaviour would be scale‐independent (e.g. Lévy walk), our study suggests that scale‐dependent processes are important components of successful foraging behaviour.
Limited scope for plasticity to increase upper thermal limits
Authors: van Heerwaarden Belinda , Kellermann Vanessa , Sgrò Carla M. 
Published: May 2016

Summary

Increases in average temperature and the frequency of extreme temperature events are likely to pose a major risk to species already close to their upper physiological thermal limits. The extent to which thermal phenotypic plasticity can buffer these changes and whether plasticity is constrained by basal tolerance levels remains unknown.

We examined the effect of developmental temperature under both constant and fluctuating thermal regimes (developmental acclimation), as well as short‐term heat hardening, on upper thermal limits (CTmax) in a tropical and temperate population of Drosophila melanogaster.

We found evidence for thermal plasticity in response to both developmental acclimation and hardening treatments; CTmax increased at warmer developmental temperatures and with a prior heat hardening treatment. However, hardening and acclimation responses were small, improving CTmax by a maximum of 1·01 °C. These results imply that overheating risk will only be minimally reduced by plasticity.

We observed significant associations between developmental temperature and both basal CTmax and hardening capacity (a measure of the extent of the plastic response). Basal CTmax increased, while hardening capacity decreased, with increasing developmental acclimation temperature. This indicates that increases in basal heat resistance at warmer temperatures may come at the cost of a reduced capacity to harden.

While plasticity in CTmax is evident in both populations of D. melanogaster we studied, plastic increases in upper thermal limits, particularly at warmer temperatures, may not be sufficient to keep pace with temperature increases predicted under climate change.

A dual‐porosity scheme for fluid/solid substitution
Authors: Glubokovskikh Stanislav , Gurevich Boris , Saxena Nishank 
Published: May 2016

ABSTRACTEstimating the impact of solid pore fill on effective elastic properties of rocks is important for a number of applications such as seismic monitoring of production of heavy oil or gas hydrates. We develop a simple model relating effective seismic properties of a rock saturated with a liquid, solid, or viscoelastic pore fill, which is assumed to be much softer than the constituent minerals. A key feature of the model is division of porosity into stiff matrix pores and compliant crack‐like pores because the presence of a solid material in thin voids stiffens the rock to a much greater extent than its presence in stiff pores. We approximate a typical compliant pore as a plane circular interlayer surrounded by empty pores. The effect of saturation of the stiff pores is then taken into account using generalized Gassmann's equations. The proposed model provides a good fit to measurements of the shear stiffness and loss factor of the Uvalde heavy‐oil rock at different temperatures and frequencies. When the pore fill is solid, the predictions of the scheme are close to the predictions of the solid squirt model recently proposed by Saxena and Mavko. At the same time, the present scheme also gives a continuous transition to the classic Gassmann's equations for a liquid pore fill at low frequencies and the squirt theory at high frequencies.
