Tropical grassy biomes: linking ecology, human use and conservation
Authors: Lehmann Caroline E. R. , Parr Catherine L. 
Published: August 2016

Tropical grassy biomes (TGBs) are changing rapidly the world over through a coalescence of high rates of land-use change, global change and altered disturbance regimes that maintain the ecosystem structure and function of these biomes. Our theme issue brings together the latest research examining the characterization, complex ecology, drivers of change, and human use and ecosystem services of TGBs. Recent advances in ecology and evolution have facilitated a new perspective on these biomes. However, there continues to be controversies over their classification and state dynamics that demonstrate critical data and knowledge gaps in our quantitative understanding of these geographically dispersed regions. We highlight an urgent need to improve ecological understanding in order to effectively predict the sensitivity and resilience of TGBs under future scenarios of global change. With human reliance on TGBs increasing and their propensity for change, ecological and evolutionary understanding of these biomes is central to the dual goals of sustaining their ecological integrity and the diverse services these landscapes provide to millions of people.
This article is part of the themed issue ‘Tropical grassy biomes: linking ecology, human use and conservation’.
The fishing and natural mortality of large, piscivorous Bull Trout and Rainbow Trout in Kootenay Lake, British Columbia (2008-2013)
Authors: Thorley Joseph L. , Andrusak Greg 
Published: August 2016

ABSTRACTBackgroundEstimates of fishing and natural mortality are important for understanding, and ultimately managing, commercial and recreational fisheries. High reward tags with fixed station acoustic telemetry provides a promising approach to monitoring mortality rates in large lake recreational fisheries. Kootenay Lake is a large lake which supports an important recreational fishery for large Bull Trout and Rainbow Trout.MethodsBetween 2008 and 2013, 88 large (≥ 500 mm) Bull Trout and 149 large (≥ 500 mm) Rainbow Trout were marked with an acoustic transmitter and/or high reward ($100) anchor tags in Kootenay Lake. The subsequent detections and angler recaptures were analysed using a Bayesian individual state-space Cormack-Jolly-Seber (CJS) survival model with indicator variable selection.ResultsThe final CJS survival model estimated that the annual interval probability of being recaptured by an angler was 0.17 (95% CRI 0.11 - 0.23) for Bull Trout and 0.14 (95% CRI 0.09 - 0.19) for Rainbow Trout. The annual interval survival probability for Bull Trout was estimated to have declined from 0.91 (95% CRI 0.77 - 0.97) in 2009 to just 0.45 (95% CRI 0.24 - 0.73) in 2013. Rainbow Trout survival was most strongly affected by spawning. The annual interval survival probability was 0.77 (95% CRI 0.68 - 0.85) for a non-spawning Rainbow Trout compared to 0.42 (95% CRI 0.31 - 0.54) for a spawner. The probability of spawning increased with the fork length for both species and decreased over the course of the study for Rainbow Trout.DiscussionFishing mortality was relatively low and constant while natural mortality was relatively high and variable. The results are consistent with Kokanee abundance as opposed to angler effort as the primary driver of short-term population fluctations in Rainbow Trout abundance. Multi-species stock assessment models need to account for the fact that large Bull Trout are more abundant than large Rainbow Trout in Kootenay Lake.
Dynamics and fate of beneficial mutations under lineage contamination by linked deleterious mutations
Authors: Pénisson Sophie , Singh Tanya , Sniegowski Paul , Gerrish Philip 
Published: August 2016

ABSTRACTBeneficial mutations drive adaptive evolution, yet their selective advantage does not ensure their fixation. Haldane’s application of single-type branching process theory showed that genetic drift alone could cause the extinction of newly-arising beneficial mutations with high probability. With linkage, deleterious mutations will affect the dynamics of beneficial mutations and might further increase their extinction probability. Here, we model the lineage dynamics of a newly-arising beneficial mutation as a multitype branching process; this approach allows us to account for the combined effects of drift and the stochastic accumulation of linked deleterious mutations, which we calllineage contamination. We first study the lineage contamination phenomenon in isolation, deriving extinction times and probabilities of beneficial lineages. We then put the lineage contamination phenomenon into the context of an evolving population by incorporating the effects of background selection. We find that the survival probability of beneficial mutations is simply Haldane’s classical formula multiplied by the correction factor, whereUis deleterious mutation rate,is mean selective advantage of beneficial mutations,κ∈ (1,ε], andε= 2 –e−1. We also find there exists a genomic deleterious mutation rate,, that maximizes the rate of production of surviving beneficial mutations, and that. Both of these results, and others, are curiously independent of the fitness effects of deleterious mutations. We derive critical mutation rates above which: 1) lineage contamination alleviates competition among beneficial mutations, and 2) the adaptive substitution process all but shuts down.
Population structure reduces the benefits from partner choice in mutualism
Authors: Akçay Erol 
Published: August 2016

AbstractMutualisms are key drivers of evolutionary and ecological processes. Understanding how different species can evolve to interact in mutually beneficial ways is an important goal of evolutionary theory, especially when the benefits require costly investments by the partners. For such costly investments to evolve, some sort of fitness feedback mechanism must exist that more than recoups the direct costs. Several such feedback mechanisms have been explored both theoretically and empirically, yet we know relatively little how they might act together, as they probably do in nature. In this paper, I model the joint action of three of the main mechanisms that can maintain symbiotic cooperation: partner choice by hosts, population structure amongst symbionts, and undirected rewards from hosts to symbionts. My results show that population structure reduces the benefit from partner choice to hosts. It may help or hinder beneficial symbionts and create positive or negative frequency dependence depending on the nature of host rewards to the symbiont. Strong population structure also makes it less likely that host choosiness and symbiont cooperation will be jointly maintained in a population. The intuition behind my results is that all else being equal, population structure reduces local variation available to the host to choose from. Thus, population structure is not always beneficial for the evolution of cooperation between species. My results also underscore the need to do full analyses of multiple mechanisms of social evolution to uncover their interactions to uncover the interactions between them.
Into the Evening: Complex Interactions in theArabidopsiscircadian clock
Authors: Huang He , Nusinow Dmitri A. 
Published: August 2016

AbstractInArabidopsis thaliana, an assembly of proteins named the evening complex (EC) has been established as an essential component of the circadian clock with conserved functions in regulating plant growth and development. Recent studies identifying EC-regulated genes and EC-interacting proteins have expanded our understanding of EC function. In this review, we focus on new progress uncovering how the EC contributes to the circadian network through the integration of environmental inputs and the direct regulation of key clock genes. We also summarize new findings of how the EC directly regulates clock outputs, such as day-length dependent and thermoresponsive growth, and provide new perspectives on future experiments to address unsolved questions related to the EC.
An integer-coded differential evolution algorithm for simple assembly line balancing problem of type 2
Authors: Zhang Haijun , Yan Qiong , Liu Yuanpeng , Jiang Zhiqiang 
Published: August 2016

Purpose
This paper aims to develop a new differential evolution algorithm (DEA) for solving the simple assembly line balancing problem of type 2 (SALBP-2).

Design/methodology/approach
Novel approaches of mutation operator and crossover operator are presented. A self-adaptive double mutation scheme is implemented and an elitist strategy is used in the selection operator.

Findings
Test and comparison results show that the proposed IDEA obtains better results for SALBP-2.

Originality/value
The presented DEA is called the integer-coded differential evolution algorithm (IDEA), which can directly deal with integer variables of SALBP-2 on a discrete space without any posterior conversion. The proposed IDEA will be an alternative in evolutionary algorithms, especially for various integer/discrete-valued optimization problems.
The impact of middle management commitment on improvement initiatives in public organisations
Authors: Alhaqbani Abdullah , Reed Deborah M , Savage Barbara M , Ries Jana 
Published: August 2016

Purpose– Top management commitment is considered a significant factor in improvement programmes, and many papers have been written about the role of top management commitment in implementing a quality management system. However, not considering other management levels’ commitment, such as middle management, may lead to issues in achieving organisational development. Public organisations that work through vertical structures may face a lack of middle management commitment, which might have a negative impact on lower and non-management staff commitment to improvement programmes. In this regard, the purpose of this paper is to examine the impact of middle management’s commitment towards improvement initiatives in public organisations.Design/methodology/approach– Empirical research with a mixed-method design used semi-structured interviews and a questionnaire to explore the current practices of continuous improvement (CI) and examine employees’ views from different management levels of the implications of current improvements in a Saudi public service organisation.Findings– The analysis indicated that the lower managers and non-management staff agree that, after the implementation of the quality management system, the organisation’s middle management showed a lack of commitment to that system. Moreover, this lack of commitment is recognised in the analysis of participants’ views of CI practices recorded in the questionnaire and interviews. This lack of commitment has caused poor employee commitment and thus a lack of problem solving in organisational departments. It is also responsible for a lack of employee involvement, the centralisation of decisions, deficiencies in terms of determining and applying training, inequality between employees and a lack of trust between employees and their managers. These issues could be managed and resolved through middle management and their commitment.Practical implications– Increasing middle managers’ awareness of the importance of their commitment to improvement initiatives can have an impact on employees’ commitment towards improvement initiatives, especially in those public organisations that have vertical/hierarchical structures. The level of commitment towards the implementation of improvement programmes needs further in-depth analyses to identify which factors influence public organisation leaders’ commitment to improvement programmes.Originality/value– The results of this study could motivate middle managers in public organisations to review their policies and to facilitate CI initiatives.

Published: August 2016

Purpose
– The purpose of this paper is to document the results of an implementation of the quality function deployment (QFD) tool in a process of a municipal administration involving: request for component support: family farming, urban and backyard agriculture that are part of the Rural Development Directorate of the Moroleón City Hall in the state of Guanajuato, México.

Design/methodology/approach
– The work is an exploratory study where the application of different quantitative techniques, database analysis, sample collection, field notes, participant observation, workshops and direct interviews were held and conducted to collect data.

Findings
– From the analysis of the requirements of quality characteristics are identified, simplified, response time reduced, assertiveness maintained and transparency in the resource allocations were assured. According to the calculations, customer expectations were clearly identified.

Originality/value
– The implementation of quality management methods such as QFD, in a municipal administration was used aimed at improving the services offered to citizens according to their expectations. It is expressed that mayors should be primarily concerned about giving the officials under their direction the necessary training to make their employment joyful with the help and use of the best tools available to provide quality results.
Empirical study on quality management for product-service systems in industrial environment
Authors: Pasch Florian , Rybski Christoffer , Jochem Roland 
Published: August 2016

Purpose– To achieve long-term customer retention a comprehensive and individual performance is increasingly important for companies from the manufacturing industry. A possibility to meet this challenge is given by Industrial Product-Service Systems (IPS2). The purpose of this paper is to discuss the results of a current study on quality management for IPS².Design/methodology/approach– After a short introduction to the topic of IPS² the paper takes the study design as its structure. It gives an overview of the demography and results of the study and ends with a conclusion.Findings– Concerning the choice of products and services the results show that customer individual performances prevail. Closely related to that is the tender of services, which are meanwhile a part of the performance offer in all industries. All in all there are already first types of IPS². The quality perception exceeds the conformance of specific requirements. Reliability and perceived quality are becoming increasingly important. An integration of customers into the quality management is the exception. Regarding the quality management in value creation chains it can be outlined that quality goals are mostly company-wide but not for the entire value creation chain. Cross-company standardized processes exist in least cases. This also applies to cross-linked CAQ-systems. Communication of quality problems is handled mainly via e-mail. Quality management in value creation chains needs a common buildup of competencies by joint trainings. In practice it is barely there. Even if the potential is seen, partners and suppliers mostly will not be considered.Originality/value– The paper considers the study results from different angles and shows the potentials of the IPS² approach. Thereby it investigates different approaches to offer a combined product-service system.

Authors: Ruman Kornel , Pietrikova Alena , Galajda Pavol , Vehec Igor , Rovensky Tibor , Kmec Martin 
Published: August 2016

Purpose
The purpose of this paper is to introduce modified in–phase and quadrature components (I–Q) demodulator based on low temperature co-fired ceramics (LTCC) dielectric substrate GreenTape 951PX for M-Sequence ultra-wide band (UWB) sensor system.

Design/methodology/approach
Microstrip low pass (LP) and band pass (BP) filters for UWB sensor systems with required properties (for both filters, minimum attenuation is −40dB in stopband, bandwidth of pass band is 6 to 8.5 GHz for BP filter and cutoff frequency is 2.5 GHz for LP filter) were designed, simulated, fabricated and measured using dielectric substrates Du Pont GreenTape 951 PX. The developed microstrip filters were integrated with all parts of I–Q demodulator on one multilayer structure based on LTCC substrate Du Pont GreenTape 951 PX.

Findings
Both type of microstrip filters integrated in the I– Q demodulator achieved better transmission characteristics in comparison with commercial available filters. It was shown that LTCC technology based on GreenTape 951PX proves good stability in gigahertz frequency and suitability for fabrication of I–Q demodulator with a multilayer approach.

Originality/value
The novelty of this work lies in substituting commercially available LP and BP filters used in I– Q demodulator by microstrip LP and BP filters with better performance and furthermore the I– Q demodulator is fabricated based on LTCC instead of previously used PCB.
Influence of ITO layer application on electrical parameters of silicon solar cells with screen printed front electrode
Authors: Drabczyk Kazimierz , Domaradzki Jaroslaw , Kulesza-Matlak Grazyna , Lipinski Marek , Kaczmarek Danuta 
Published: August 2016

Purpose
The purpose of this paper was investigation and comparison of electrical and optical properties of crystalline silicon solar cells with ITO or TiO2 coating. The ITO, similar to TiO2, is very well transparent in the visible part of optical radiation; however, its low resistivity (lower that 10-3 Ohm/cm) makes it possible to use simultaneously as a transparent electrode for collection of photo-generated electrical charge carriers. This might also invoke increasing the distance between screen-printed metal fingers at the front of the solar cell that would increase of the cell’s active area. Performed optical investigation showed that applied ITO thin film fulfill standard requirements according to antireflection properties when it was deposited on the surface of silicon solar cell.

Design/methodology/approach
Two sets of samples were prepared for comparison. In the first one, the ITO thin film was deposited directly on the crystalline silicon substrate with highly doped emitter region. In the second case, the TCO film was deposited on the same type of silicon substrate but with additional ultrathin SiO2 passivation. The fingers lines of 80 μm width were then screen-printed on the ITO layer with two different spaces between fingers for each set. The influence of application of the ITO electrode and the type of metal electrodes patterns on the electrical performance of the prepared solar cells was investigated through optical and electrical measurements.

Findings
The electrical parameters such as short-circuit current (Jsc), open circuit voltage (Voc), fill factor (FF) and conversion efficiency were determined on a basis of I-V characteristics. Short-circuit current density (Jsc) was equal to 32 mA/cm2 for a solar cell with a typical antireflection layer and 31.5 mA/cm2 for the cell with ITO layer, respectively. Additionally, electroluminescence of prepared cells was measured and analysed.

Originality/value
The influence of the properties of ITO electrode on the electrical performance of crystalline silicon solar cells was investigated through complex optical, electrical and electroluminescence measurements.
Bank social responsibility and the use of money
Authors: Ferreira Gilciney , Mattoso Cecilia Queirós 
Published: August 2016

Purpose
The purpose of the present research is first to assess the financial education’s effectiveness, examining how a specific communication regarding the use of money could help new consumers from low-income families avoid insolvency. The second is to analyse the impact of this corporate social responsibility (CSR) activity on a Brazilian bank’s image.

Design/methodology/approach
The research used a qualitative methodology based on in-depth interviews using three advertising films, which served as an enhanced element to prompt students to evaluate the discourse of sensible use of money and credit and the bank’s image.

Findings
The results showed that the students are very receptive to the ideas shown by the bank advertising films. Nevertheless, the interviewees showed a certain degree of suspicion toward the initiative and intentions of the bank. The perceived corporate image was clearly ambiguous, with the financial institution showing its advertising film about the careful use of money in complete contrast to actual bank branch practices in which employees offer and encourage young students from low-income families to get loans and credit cards. The bank became more socially responsible merely to cut costs and as a consequence did not improve its image.

Practical implications
For CSR in banks to be real and have a positive impact on society, the authors suggest that the bank enter into a cooperation or sponsorship agreement with the federal government or any public sector institution or non-governmental organizations. The form, the arguments and the language of the bank’s financial education campaign examined in this article seemed to be capable of serving social purposes or benefiting society.

Social implications
Educating consumers in the conscious use of money reduces delinquency rates and increases banks’ profits while, at the same time, benefiting society economically. The bank’s positive experience in terms of financial education could help the Brazilian government and other institutions with the same purpose. The advertising campaign provides some insights for the Brazilian government financial education program to which it has given high priority (BCB, 2015).

Originality/value
The article expands studies on CSR in developing countries and of attitudes toward it in the emerging middle class, two issues that have received scant attention. The study reinforces Carroll and Shabana’s view (2010) that companies are becoming more socially responsible merely to cut costs and Porter and Kramer’s call that to be really strategic the action must not appear to be mitigating the very harm it has caused.
The Genus Heracleum: A Comprehensive Review on Its Phytochemistry, Pharmacology, and Ethnobotanical Values as a Useful Herb
Authors: Bahadori Mir Babak , Dinparast Leila , Zengin Gokhan 
Published: August 2016

AbstractHeracleum species, also known as hogweed, are traditionally used as food additives, spices, and flavoring agents. Moreover, these plants are widely used in folklore medicine for the treatment of many disorders such as inflammation, flatulence, stomachache, epilepsy, psoriasis, and as carminative, wound healing, antiseptic, antidiarrheal, tonic, digestive, pain killer, analgesic, and anticonvulsant agents. The genus Heracleum has broad pharmacological activities: anti‐inflammatory, antimicrobial, anticholinesterase, anti‐oxidant, antiviral, cytotoxic, and anticarcinogenic. A total of 94 compounds have been isolated from plants of the Heracleum genus, all indicating vital biological activities. Also, about 50 compounds have been identified as major components in their essential oils. The genus is rich in several types of bioactive coumarin compounds, with huge potential for the discovery of new coumarins. Various parts of these plants produce essential oils (mainly aliphatic esters and monoterpenes) with a wide spectrum of biological activities. Heracleum species have great potential for applications in the food, cosmetics, perfumery, and pharmaceutical industries due to their broad ethnobotanical uses and pharmacological properties. Accordingly, this review aims to categorize updated and comprehensive information on ethnobotanical uses, phytochemistry, and pharmacology of Heracleum species in order to open new perspectives for future studies, including possible uses as functional ingredients in food products.
