Cross-generational analysis of information seeking behavior of smartphone users
Authors: Zhitomirsky-Geffet Maayan , Blau Maya 
Published: September 2017

Purpose
The purpose of this paper is to investigate the predictive factors of information seeking behavior of smartphone users from the cross-generational perspective. Based on existing literature, the two most popular types of information seeking behavior of smartphone users were determined: social information seeking behavior; and functional/cognitive information seeking behavior.

Design/methodology/approach
A questionnaire comprising 66 questions was administered online to 216 smartphone users of three age groups according to three generations: generation X, Y (millennials) and Z. Several predictive factors were examined for each of these information seeking behavior types: generation, gender, personality traits (the Big Five), daily usage time, period of ownership, various application utilization and the level of emotional gain from smartphones.

Findings
There is a trade-off between the two types of information seeking behavior. Also, men exhibited significantly more functional/cognitive information seeking behavior than women, and younger generations reported significantly higher emotional gain and social information seeking behavior than older generations. Interestingly, significant differences in smartphone apps’ utilization, information seeking behavior types and their predictive factors were found among users from different generations. Extraversion was positively related to social information seeking behavior only for generations X and Y, while WhatsApp usage was one of the strongest predictive factors only for generation Z.

Practical implications
This research has practical implications for information system design, education, e-commerce and libraries.

Originality/value
This is a first study that systematically examines predictive factors of the two prominent types of information seeking behavior on smartphones from the cross-generational perspective.
Gender and image sharing on Facebook, Twitter, Instagram, Snapchat and WhatsApp in the UK
Authors: Thelwall Mike , Vis Farida 
Published: September 2017

Purpose
Despite the on going shift from text-based to image-based communication in the social web, supported by the affordances of smartphones, little is known about the new image sharing practices. Both gender and platform type seem likely to be important, but it is unclear how. The paper aims to discuss these issues.

Design/methodology/approach
This paper surveys an age-balanced sample of UK Facebook, Twitter, Instagram, Snapchat and WhatsApp image sharers with a range of exploratory questions about platform use, privacy, interactions, technology use and profile pictures.

Findings
Females shared photos more often overall and shared images more frequently on Snapchat, but males shared more images on Twitter, particularly for hobbies. Females also tended to have more privacy-related concerns but were more willing, in principle, to share pictures of their children. Females also interacted more through others’ images by liking and commenting on them. Both genders used supporting apps but in different ways: females applied filters and posted to albums whereas males retouched photos and used photo organising apps. Finally, males were more likely to be alone in their profile pictures.

Practical implications
Those designing visual social web communication strategies to reach out to users should consider the different ways in which platforms are used by males and females to optimise their message for their target audience.

Social implications
There are clear gender and platform differences in visual communication strategies. Overall, males may tend to have more informational and females more relationship-based, skills or needs.

Originality/value
This is the first detailed survey of electronic image sharing practices and the first to systematically compare the current generation of platforms.

Metamodel-based design optimization employing a novel sequential sampling strategy
Authors: Shu Leshi , Jiang Ping , Wan Li , Zhou Qi , Shao Xinyu , Zhang Yahui 
Published: September 2017

Purpose
Metamodels are widely used to replace simulation models in engineering design optimization to reduce the computational cost. The purpose of this paper is to develop a novel sequential sampling strategy (weighted accumulative error sampling, WAES) to obtain accurate metamodels and apply it to improve the quality of global optimization.

Design/methodology/approach
A sequential single objective formulation is constructed to adaptively select new sample points. In this formulation, the optimization objective is to select a sample point with the maximum weighted accumulative predicted error obtained by analyzing data from previous iterations, and a space-filling criterion is introduced and treated as a constraint to avoid generating clustered sample points. Based on the proposed sequential sampling strategy, a two-step global optimization approach is developed.

Findings
The proposed WAES approach and the global optimization approach are tested in several cases. A comparison has been made between the proposed approach and other existing approaches. Results illustrate that WAES approach performs the best in improving metamodel accuracy and the two-step global optimization approach has a great ability to avoid local optimum.

Originality/value
The proposed WAES approach overcomes the shortcomings of some existing approaches. Besides, the two-step global optimization approach can be used for improving the optimization results.
Optimal sensors and actuators placement for large-scale unstable systems via restricted genetic algorithm
Authors: Seyed Sakha Masoud , Shaker Hamid Reza 
Published: September 2017

Purpose
One of the fundamental problems in control systems engineering is the problem of sensors and actuators placement. Decisions in this context play a key role in the success of control process. The methods developed for optimal placement of the sensors and actuators are known to be computationally expensive. The computational burden is significant, in particular, for large-scale systems. The purpose of this paper is to improve and extend the state-of-the-art methods within this field.

Design/methodology/approach
In this paper, a new technique is developed for placing sensor and actuator in large-scale systems by using restricted genetic algorithm (RGA). RGA is a kind of genetic algorithm which is developed specifically for sensors and actuator placement.

Findings
Unlike its other counterparts, the proposed method not only supports unstable systems but also requires significantly lower computations. The numerical investigations have confirmed the advantages of the proposed methods which are clearly significant, in particular, in dealing with large-scale unstable systems.

Originality/value
The proposed method is novel, and compared to the methods which have already been presented in literature is more general and numerically more efficient.
A state space boundary element method for elasticity of functionally graded materials
Authors: Cheng Changzheng , Han Zhilin , Niu Zhongrong , Sheng Hongyu 
Published: September 2017

Purpose
The state space method (SSM) is good at analyzing the interfacial physical quantities in laminated materials, while it has difficulty in calculating the mechanical quantities of interior points, which can be easily evaluated by the boundary element method (BEM). However, the material has to be divided into many subdomains when the traditional BEM is applied to analyze the functionally graded material (FGM), so that the computational amount will be increased enormously. This study aims to couple these two methods to strengthen their advantages and overcome their disadvantages.

Design/methodology/approach
Herein, a state space BEM in which the SSM is coupled by the BEM is proposed to analyze the elasticity of FGMs, where one BEM domain is set and the others belong to SSM domains. The discretized elements occur only on the boundary of the BEM domain and at the interfaces between different SSM domains. In SSM domains, the horizontal interfaces of FGMs are discretized by linear elements and the variables along the vertical direction are yielded by the precise integration method.

Findings
The accuracy of the proposed method is verified by comparing the present results with the ones from the finite element method (FEM). It is found that the present method can provide accurate displacements and stresses in the FGMs by fewer freedom degrees in comparison with the FEM. In addition, the present method can provide continuous interfacial stresses at the interfaces between different material domains, while the interfacial stresses by the FEM are discontinuous.

Originality/value
The system equations of the state space BEM are built by combining the boundary integral equation with the state equations according to the continuity conditions at the interfaces. The mechanical parameters of any inner point can be evaluated by the boundary integral equation after the unknowns on the boundaries and interfaces are determined by the system equation.
GDP, energy consumption and financial development in Italy
Authors: Magazzino Cosimo 
Published: September 2017

PurposeThis study aims to explore the relationship among energy consumption, real income, financial development and oil prices in Italy over the period 1960-2014.Design/methodology/approachDifferent econometric techniques – such as the General Methods of Moment (GMM) or the AutoRegressive Distributed Lags (ARDL) bounds test – are usually used in the empirical analysis. Moreover, both the Toda and Yamamoto causality tests and the Granger causality tests are applied to the data.FindingsThe results of unit root and stationarity tests show that the variables are non-stationary at levels, but stationary in first-differences form, or I(1). The ARDL boundsF-test reveals an evidence of a long-run relationship among the four variables at 1% significance level. Moreover, an increase in real GDP and oil prices has a significant effect on energy consumption in the long run. The coefficients of estimated error correction term are also negative and statistically significant. In addition, the paper explores the causal relationship between the variables by using a VAR framework, with Toda and Yamamoto but also Granger causality tests, within both multivariate and bivariate systems. The findings indicate that energy consumption is affected by real GDP.Originality/valueThe study also filled the literature gap of applying ARDL technique to examine this relevant issue for Italy.
The role of wilderness experiences in leaders’ development toward authentic leadership
Authors: van Droffelaar Boy , Jacobs Maarten 
Published: September 2017

Purpose
The purpose of this paper is to investigate the impact of leaders’ wilderness experiences on intentions to transform leadership behaviors toward authentic leadership.

Design/methodology/approach
Content analysis was used on trail reports made by participants of a wilderness-based leadership program. Participants (n=97) were leaders working in business and institutional settings, both males and females. Participants were asked to write personal reports within two weeks after the training program about their wilderness experiences, and related behavioral intentions.

Findings
The analyses revealed four categories of leaders’ peak experiences: heightened sense of self, awareness of one’s core values, deep connected attention, and being in full presence. These peak experiences triggered intentions to change future leadership behaviors: to be more aware of self, to live by the inner compass, to improve careful listening, and to become more transparent. These intentions closely resonate with the core components of authentic leadership.

Research limitations/implications
The authors’ sample is characterized by developmental readiness: people who are already willing to change. However, developmental ready leaders are the subset of leaders that is particularly relevant studying change toward authentic leadership. Another limitation is intentions are assessed, and hence knowledge about actual changes in leadership style requires additional research.

Practical implications
The attributes of the transformation program that foster change as revealed here – being in another world, facing unfamiliar challenges, peer-to-peer learning – can be flexibly adopted and implemented in a wide range of leadership transformation programs.

Originality/value
By demonstrating that being immersed in nature can act as a significant life event that has the potential to foster authentic leadership, this study provides an original contribution to the literature on strategies for intra-personal leadership development.
Supplementing small farms with native mason bees increases strawberry size and growth rate
Authors: Horth Lisa , Campbell Laura A. 
Published: September 2017

Abstract

Pollination services, especially those of bees, play a vital role in agriculture. Declining honeybee populations require us to find alternative solutions for sustainable agriculture. Native bees are proving to be efficient pollinators. Mason bees (Osmia lignaria) provide valuable pollinator services for some woody orchard species, but their value as pollinators for herbaceous crops is largely untested.

We assessed the effectiveness of O. lignaria supplementation on nine strawberry farms over two growing seasons. We specifically selected mason bees for this work because they emerge from cocoons in the springtime, when few other bees are available for pollination. Cocoons are easily deployed on farms and emerged bees have a small flight radius, so they remain localized. We placed cocoons on one side of each berry farm plot (our mason bee addition treatment) but not on the opposite side (our control). We tagged and monitored berries on nine farms throughout the growing season. We performed statistical comparisons of berries from the treatment and control for differences in berry growth rate and size. In addition, we supplemented farms with native bee homes constructed from three materials (bamboo, Phragmites and wood). This allowed us to determine whether adult mason bees would produce a subsequent generation of bees on farms and whether the bees had a preference for nest material type.

Our work demonstrates that mason bees can be used successfully to pollinate herbaceous berry crops. We found that berry growth rate was significantly higher and berry volume was significantly larger for berries from the treatment relative to the control. We also found that adult bees successfully utilized the bee homes for laying the next generation of offspring and that bees colonized bamboo homes more than other home types.

Synthesis and applications. Our results are the first to show that native mason bees (Osmia lignaria) can be used successfully to provide pollination services on strawberry farms. Their use results in the production of bigger berries and faster berry growth rates than managed honeybees alone. Mason bees overwinter (and can be purchased) in cocoons, offering great potential for efficient and effective pollination services, for a variety of agricultural applications across different geographical regions. The availability of suitable nesting sites and protection of subsequent generations of cocoons from wasp parasitization warrant future consideration.

Published: September 2017

SummaryThis study demonstrated the utilization of unprocessed biodiesel waste as a carbon feedstock for Pseudomonas mendocinaCH50, for the production of PHAs. A PHA yield of 39.5% CDM was obtained using 5% (v/v) biodiesel waste substrate. Chemical analysis confirmed that the polymer produced was poly(3‐hydroxyhexanoate‐co‐3‐hydroxyoctanoate‐co‐3‐hydroxydecanoate‐co‐3‐hydroxydodecanoate) or P(3HHx‐3HO‐3HD‐3HDD). P(3HHx‐3HO‐3HD‐3HDD) was further characterized and evaluated for its use as a tissue engineering scaffold (TES). This study demonstrated that P(3HHx‐3HO‐3HD‐3HDD) was biocompatible with the C2C12 (myoblast) cell line. In fact, the % cell proliferation of C2C12 on the P(3HHx‐3HO‐3HD‐3HDD) scaffold was 72% higher than the standard tissue culture plastic confirming that this novel PHA was indeed a promising new material for soft tissue engineering.

AbstractIn the European Union (EU), the regulatory framework regarding diagnostic allergen extracts is currently in the process of being implemented at the national level. Due to these regulations, the initial and periodic renewal expenses for the registration of diagnostic allergen extracts may render extract production unprofitable. Consequently, many extracts may be at risk of removal from the market. The current survey, which was conducted by a task force of the European Academy of Allergy and Clinical Immunology, aimed to assess the current practice of allergy diagnosis in Europe. This survey revealed that skin tests continue to be the main diagnostic procedure and are used as the first option in almost two‐third of all types of allergic diseases and in 90% of individuals suffering from respiratory allergies. Therefore, there is a need to ensure the availability of high‐quality allergen extracts to maintain the common diagnostic procedures used by EU professionals. To reach this goal, it is necessary to align efforts and establish active partnerships between manufacturers, relevant scientific societies, consumer organizations and authorities to maintain the availability of these diagnostic tools.

AbstractMobile technology has been used to appraise allergic rhinitis control, but more data are needed. To better assess the importance of mobile technologies in rhinitis control, the ARIA (Allergic Rhinitis and its Impact on Asthma) score ranging from 0 to 4 of the Allergy Diary was compared with EQ‐5D (EuroQuol) and WPAI‐AS (Work Productivity and Activity Impairment in allergy) in 1288 users in 18 countries. This study showed that quality‐of‐life data (EQ‐5D visual analogue scale and WPA‐IS Question 9) are similar in users without rhinitis and in those with mild rhinitis (scores 0‐2). Users with a score of 3 or 4 had a significant impairment in quality‐of‐life questionnaires.

Published: September 2017

AbstractBackgroundAtopic dermatitis (AD) is a chronic skin inflammation that affects children and adults worldwide, but its pathogenesis remains ill‐understood.MethodsWe show that a single application of OVA to mouse skin initiates remodeling and cellular infiltration of the hypodermis measured by a newly developed computer‐aided method.ResultsImportantly, we demonstrate that skin mast cell (MC) activation and local sphingosine‐1‐phosphate (S1P) are significantly augmented after OVA treatment in mice. Deficiency in sphingosine kinase (SphK)1, the S1P‐producing enzyme, or in MC, remarkably mitigates all signs of OVA‐mediated remodeling and MC activation. Furthermore, skin S1P levels remain unchanged in MC‐deficient mice exposed to OVA. LPS‐free OVA does not recapitulate any of the precursor signs of AD, supporting a triggering contribution of LPS in AD that, per se, suffice to activate local MC and elevate skin S1P.ConclusionWe describe MC and S1P as novel pathogenic effectors that initiate remodeling in AD prior to any skin lesions and reveal the significance of LPS in OVA used in most studies, thus mimicking natural antigen (Ag) exposure.

AbstractObjectivesCognitive dysfunction is a key feature of bipolar disorder (BD). However, not much is known about its temporal stability, as some studies have demonstrated a neurodegenerative model in BD while others have shown no change in cognitive functioning over time. Building upon our prior work, which examined the natural course of executive functioning, the current study aimed to investigate the natural course of memory, emotion processing, and fine motor dexterity over a 5‐year period in BD and healthy control (HC) samples.MethodsUsing a 5‐year longitudinal cohort, 90 individuals with BD and 17 HCs were administered a battery of neuropsychological tests at study baseline and at 1 and 5 years after study entry that captured four areas of cognitive performance: visual memory, auditory memory, emotion processing, and fine motor dexterity.ResultsLatent growth curve modeling showed no group differences in the slopes of any of the cognitive factors between the BD and HC groups. Age at baseline was negatively associated with visual memory, emotion processing, and fine motor dexterity. Education level was positively associated with auditory and visual memory and fine motor. Female gender was negatively associated with emotion processing.ConclusionsExtending our prior work on longitudinal evaluation of executive functioning, individuals with BD show similar linear change in other areas of cognitive functioning including memory, emotion processing, and fine motor dexterity as compared to unaffected HCs. Age, education, and gender may have some differential effects on cognitive changes.
