AbstractLarge efforts have been deployed in developing methods to estimate methane emissions from cattle. For large scale applications, accurate and inexpensive methane predictors are required. Within a livestock precision farming context, the objective of this work was to integrate real-time data on animal feeding behaviour with anin silicomodel for predicting the individual dynamic pattern of methane emission in cattle. The integration of real-time data with a mathematical model to predict variables that are not directly measured constitutes a software sensor. We developed a dynamic parsimonious grey-box model that uses as predictor variables either dry matter intake (DMI) or the intake time (IT). The model is described by ordinary differential equations. Model building was supported by experimental data of methane emissions from respiration chambers. The data set comes from a study with finishing beef steers (cross-bred Charolais and purebred Luing finishing). DMI and IT were recorded with load cells. A total of 37 individual dynamic patterns of methane production were analysed. Model performance was assessed by concordance analysis between the predicted methane output and the methane measured in respiration chambers. The model predictors DMI and IT performed similarly with a Lin’s concordance correlation coefficient (CCC) of 0.78 on average. When predicting the daily methane production, the CCC was 0.99 for both DMI and IT predictors. Consequently, on the basis of concordance analysis, our model performs very well compared with reported literature results for methane proxies and predictive models. Since IT measurements are easier to obtain than DMI measurements, this study suggests that a software sensor that integrates ourin silicomodel with a real-time sensor providing accurate IT measurements is a viable solution for predicting methane output in a large scale context.ImplicationsReducing methane emissions from ruminants is a major target for sustainable and efficient livestock farming. For the animal, methane production represents a loss of feed energy. For the environment, methane exerts a potent greenhouse effect. Methane mitigation strategies require accurate, non-invasive and inexpensive techniques for estimating individual methane emissions on farm. In this study, we integrate measurements of feeding behaviour in cattle and a mathematical model to estimate individual methane production. Together, model and measurements form a software sensor that efficiently predicts methane output. Our software sensor is a promising approach for estimating methane emissions at large scale.

Published: April 2018

AbstractTelomere maintenance is essential for the long-term proliferation of human pluripotent stem cells, while their telomere length set point determines the proliferative capacity of their differentiated progeny. The shelterin protein TPP1 is required for telomere stability and elongation, but its role in set point establishment remains elusive. Here, we characterize the contribution of TPP1 isoforms and residues outside the TEL patch, TPP1’s telomerase interaction domain, to telomere length control. We demonstrate that TPP1L, the longer minor isoform of TPP1, can partially compensate for loss of the more abundant shorter isoform, TPP1S. Both TPP1S knockout and complete TPP1 knockout cell lines (TPP1 KO) show telomere shortening. However, TPP1S KO cells are able to stabilize short telomeres while TPP1 KO cells do not and die. We compare these phenotypes with that of TPP1L104A/L104A mutant cells that like the TPP1S KO have short stable telomeres. In contrast to TPP1S KO, TPP1L104A/L104A cells respond to increased telomerase. However, TPP1L104A/L104A’s sensitivity to shelterin-mediated feedback is altered, revealing TPP1L104A/L104A as a new type of shelterin mutant with aberrant set point regulation.

Published: April 2018

SUMMARYHow growing cells cope with size expansion while ensuring mechanical integrity is not known. In walled cells, such as those of microbes and plants, growth and viability are both supported by a thin and rigid encasing cell wall (CW). We deciphered the dynamic mechanisms controlling wall surface assembly during cell growth, using a novel sub-resolution microscopy approach to monitor CW thickness in live rod-shaped fission yeast cells. We found that polar cell growth yielded wall thinning, and that thickness negatively influenced growth. Thickness at growing tips exhibited oscillating behavior with thickening phases followed by thinning phases, indicative of a delayed feedback promoting thickness homeostasis. This feedback was mediated by mechanosensing through the cell wall integrity pathway, which probes strain in the wall to adjust synthase localization and activity to surface growth. Mutants defective in thickness homeostasis lysed by rupturing the wall demonstrating its essential role for walled cell survival.
Participatory budgeting as a form of dialogic accounting in Russia
Authors: Aleksandrov Evgenii , Bourmistrov Anatoli , Grossi Giuseppe 
Published: April 2018

Purpose
The purpose of this paper is to investigate how participatory budgeting (PB), as a form of dialogic accounting, is produced in practice.

Design/methodology/approach
This is a qualitative case study of PB development for the period 2013-2016 in one Russian municipality. Based on triangulation of in-depth semi-structured interviews, documentary analysis, videotape data and netnographic observation, the authors employ ideas of dialogic accounting and institutional work.

Findings
The study shows that the PB experiment, which began with dialogic rhetoric, in reality, had very limited dialogic effects. However, the authors also observed that the PB dynamics over time made the practice neither inherently monologic nor dialogic. The authors explained such transformations by the way in which the individual reflexivity of actors altered when carrying out institutional work. Curiosity reflexivity was the most essential, triggering different patterns of institutional work to set up the PB experiment. However, further, the authors demonstrated that, over the course of the experiment’s development, the institutional work was trapped by various actors’ individual reflexivity forms and in this way limited PB’s dialogic potential.

Originality/value
The study shows the importance of understanding and managing individuals’ reflexivity, as it shapes the institutional work performed by different actors and, therefore, influences the direction of both the design and materialization of dialogic accounting experiments such as PB. In a broader sense, this also influences the way in which democratic governance is developed, losing democratization potential.
The use and non-use of the government financial report by Maltese Members of Parliament
Authors: Caruana Josette , Farrugia Brady 
Published: April 2018

Purpose
The purpose of this paper is to examine the use and non-use of the Government Financial Report by Maltese Members of Parliament (MPs). It refers to information overload theory to analyse the gap between financial reports and their relevance for decision making.

Design/methodology/approach
A mix of qualitative (interviews) and quantitative (questionnaire) research tools are applied, with the Maltese MPs being the research participants. This method is acclaimed to be comprehensive, but this study highlights certain disadvantages when applied in the political arena.

Findings
The characteristics of the information itself could be the main cause of information overload, resulting in the non-use of the financial report for decision making. Politicians refer to financial data for their decision making, but not to the data presented in the financial report. Irrespective of the politician’s professional background, the data in the financial report is perceived as incomplete and outdated.

Practical implications
The cause of information overload and its effects are important considerations for preparers of financial information and accounting standard setters, if they wish that their production is relevant for decision makers.

Originality/value
There is an increase in research concerning politicians’ use of budgetary and performance information, at local and regional levels of government. This study investigates exclusively the use of the financial report by politicians at central level, in a politically stable environment.
Connecting local and global technological knowledge sourcing
Authors: Cantwell John , Zaman Salma 
Published: April 2018

PurposeThrough increasing globalization, cities are becoming increasingly interconnected with each other. To remain competitive, it is necessary for cities to combine complementary non-local sources of knowledge with local knowledge sources. The authors contend that an increase in non-local knowledge sourcing tends to enhance local knowledge sourcing too. The purpose of this study is to examine the influence of international knowledge sources on the capacity to build upon local knowledge sources in a city region. In addition, the authors investigate whether information and communication technologies (ICT) knowledge sources have a bigger impact than do other fields of knowledge on local knowledge connectivity.Design/methodology/approachUsing the US Patent and Trademark Office data, the authors study knowledge sourcing trends for the years 1980-2016 across 33 global cities. Backward patent citations from these granted patents are used to identify the location of inventors of prior knowledge sources, and the geography of knowledge building connections over time is assessed by using the inventor locations of cited (source) and citing (recipient) patents.FindingsThe authors show that international knowledge sourcing is highly connected with local knowledge sourcing. The authors also find that ICT have a significant effect on this relationship. However, there are significant differences across cities in the extent and nature of this relationship.Originality/valueThis study contributes to the literature on the changing geography of knowledge connections. It provides a detailed picture of changing knowledge sourcing trends at a city region level, and it improves our understanding of the role played by a variety of knowledge connections in helping a city remain competitive.

Authors: Krishnamoorthi Kavitha , Jagannathan Srinivasan 
Published: April 2018

Purpose
The purpose of this paper is to present a laboratory-based test method to evaluate colourfastness of silk fabrics when perfumes are applied on it.

Design/methodology/approach
Three different simple methods like simple spray method, rubbing and perspirometer were used. In simple spray method, standard quantity was sprayed from constant distance. In rubbing fastness tester, perfume sprayed fabric was subjected to rubbing. Similarly, perfume sprayed fabric was kept in perspirometer similar to perspiration fastness testing method. As a new method, perfume applied fabric was again treated with perspiration solution and colour change and staining were observed.

Findings
On comparing the different methods, it is suggested that method using fabric applied with both perfume and perspiration solution kept in perspirometer will simulate actual wearing condition and will give the actual effect of Perfume on fabric colour.

Originality/value
So far, no standard method is available. Hence, this test method will enable fabric manufacturers, perfume manufacturers and customers to be aware of effect of perfumes on fabric colour and aesthetics.
Effect of strain rate on the tensile performance of woven para-aramid fabrics
Authors: Seretis Georgios V. , Theodorakopoulos Ioannis D. , Manolakos Dimitrios E. , Provatidis Christopher G. 
Published: April 2018

Purpose
Para-aramid fabrics see service in a great variety of applications, such as heavy weight lifting applications, penetration protective multilayer panels, etc. It is, therefore, increasingly important to understand the strain rate range at which the fabric has optimum mechanical properties. Although this is a field that has not been studied before, it is of great significance since it allows for the determination of the fabric’s layer location within the multilayered structure which offers maximum overall performance. The paper aims to discuss this issue.

Design/methodology/approach
Rectangular strips of PARAX 300 S8 woven para-aramid fabric underwent uniaxial tensile tests at various extension rates. The angle between two fibers at the center of each specimen was measured after the fabrics were elongated at different tensile extensions. This recovery angle was determined by visual analysis of the test video recordings after specimen unloading. Based on this, the recovery of the weaving form after unloading was also estimated for each tensile extension. A recovery degree based deformation characterization of the sections of a typical load/extension curve has been introduced.

Findings
The fabric does not appear to be strain rate sensitive for a strain rate range of 0.03 s-1 to 0.53 s-1, and its load/extension characteristics are generally not affected by the extension rate. However, break load and maximum elongation values appear reduced at actuator velocity of 2,400 mm/min and enhanced at 3,600 mm/min. Finally, the effect of extension rate on the different deformation zones of the material is reported and discussed.

Originality/value
The current research work offers a novel approach for the investigation of non-standard response of woven para-aramid fabrics when subjected to tensile loading under various strain rates. Additionally, a new approach is introduced to explain in detail the deformation zones based on the recovery degree of the fiber orientation angle after unloading.
Linking the emotional maturity factors and self-disclosure: a study of Indian organizations
Authors: Nehra Nagendra Singh , Rangnekar Santosh 
Published: April 2018

Purpose
This paper aims to discuss a survey, carried out by the authors, of 256 employees employed in public and private manufacturing organizations in north India, to determine if emotional maturity factors have positive association with self-disclosure in the Indian context. Specifically, capitalization and social exchange theories support as major theoretical framework to examine the proposed relationship.

Design/methodology/approach
The sample data used were collected through a cross-sectional survey-based research design and a convenience sampling method. Totally, 290 questionnaires were distributed during office hours, administered with a paper and pencil survey. However, in the final analysis, only 256 responses were considered for analysis using multiple hierarchical regression analysis.

Findings
Results reveal that all dimensions of emotional maturity positively associated with self-disclosure. This study fully supports the applicability of capitalization and social exchange theories while explaining the proposed relationships in Indian context.

Research limitations/implications
The present study used a cross-sectional survey-based research design; future studies may use longitudinal research design.

Practical implications
The study shows how to develop collective work culture and supportive work climate through emotional maturity and self-disclosure. Thus, employees become accustomed to multicultural team and cultural diversity issues at the workplace. The study also recommended that the organized employees social gathering will create positive feeling, and that such feelings of belonging to a group among employees will give reasons for self-disclosure and finally, in turn, to employee effectiveness.

Originality/value
More predominantly, the proposed association has not been examined before and the findings serve as a potential policy guideline for the self-disclosure literature through the perspective of capitalization and social exchange theories in understudied non-US cultures such as India.
Co-evolutionary dynamics in the music industry
Authors: Uli Vincenzo 
Published: April 2018

Purpose
What effects does radical innovation produce on the dialectical relationship between enterprises and their environment? In this paper, by adopting the dynamic adaptation matrix methodological framework, the author addresses this research question by discussing the evolution of the music industry in the period of 1999-2013. The purpose of this study is to identify possible co-evolutionary adaptation paths, namely, virtuous or contradictory adaptation cycles.

Design/methodology/approach
The paper is presented as a descriptive comparative case study about the major changes that have occurred in the sector, and this could be of interest to the industry stakeholders. The paper also contributes to the debate about co-evolution as it is an empirical implementation of the adaptation matrix and sheds light on the main environmental dynamics.

Findings
The author found that for a low level of environmental determinism and moderate degree of strategic choice, cost leadership strategy dominates other strategic options. For moderate levels of environmental determinism, differentiation-marketing strategy ensures a better performance than differentiation-innovation strategy. Finally, for a high level of both environmental determinism and strategic choice, differentiation-innovation strategy is the best strategic option among differentiation strategies.

Practical implications
The adaptation matrix, especially in its dynamic form, can be applied to understand the changes within a sector with a co-evolutionary lens and to analyze critically the strategic choices enacted by the market’s incumbents.

Originality/value
This study may have useful implications for both scientific research and managerial practice. In fact, it is intended for all scholars and practitioners interested in exploring the nature of organizational adaptation, especially in industries affected by major technological changes, such as the music industry, which only recently has been considered as a fertile ground for research.
The contagion effect between the oil market, and the Islamic and conventional stock markets of the GCC country
Authors: Mezghani Taicir , Boujelbène Mouna 
Published: April 2018

PurposeThis study aims to investigate the transmission of shock between the oil market and the Islamic and conventional stock markets of the Gulf Cooperation Council (GCC) countries during the oil shocks of 2008 and 2014.Design/methodology/approachThis study uses two models. First, the dynamic conditional correlation–generalized autoregressive conditionally heteroskedastic model has been used to capture the fundamental contagion effects between the oil market and the Islamic and conventional stock markets during the tranquil and turmoil-crisis periods of 2008-2014. Second, the filter of Kalman has been used to capture the effects of pure contagion between the oil market and the GCC Islamic and conventional stock markets. The authors analyze the dynamic correlation between forecasting errors of oil returns and stock returns of GCC Islamic and GCC conventional indices.FindingsThe main findings of this investigation are: first, the estimation of the dynamic conditional correlation– generalized autoregressive conditionally heteroskedastic model for oil market and the Islamic and conventional stock markets proves that the Islamic and conventional stock markets and oil market displayed a significant increase in the dynamic correlation during the turmoil period, from mid-2008 and mid-2014. This proves the existence of contagion between the markets studied. Second, the authors analyze the dynamic correlation between forecasting errors of oil returns and stock returns of GCC Islamic and GCC conventional indices. They show a strong increase in the correlation coefficients between the oil market and the conventional GCC stock markets, and between the conventional and Islamic GCC stock markets during the oil crisis of 2014. However, there is no change in regime in the figure of the correlation coefficient between the oil market and the GCC Islamic stock markets during the 2008 financial crisis. This pure contagion is mainly attributed to the herding bias in 2014 oil crisis.Originality/valueThis study contributes to identifying the contribution of herding bias on the volatility transmission between the oil markets, and the GCC Islamic and conventional stock market, especially during two controversial shocks: the 2008 oil-price increase and the 2014 oil drop.
Using message strategy to drive consumer behavioral engagement on social media
Authors: Tafesse Wondwesen , Wien Anders 
Published: April 2018

PurposeThis study aims to examine how message strategy influences consumer behavioral engagement in social media. To this end, the study develops a comprehensive typology of branded content in social media and tests for its effect on consumer behavioral engagement.Design/methodology/approachA sample of brand posts derived from the official Facebook pages of top corporate brands was double-coded using an elaborate coding instrument. Message strategy was operationalized using three main message strategies (i.e. informational, transformational and interactional) and their paired combinations. Consumer behavioral engagement was operationalized using consumer actions of liking and sharing brand posts. Proposed relationships were tested with MANCOVA and univariate ANOVAs.FindingsResults indicate that the transformational message strategy is the most powerful driver of consumer behavioral engagement, while no significant difference is observed between the informational and the interactional message strategies. Further, complementing the informational and interactional message strategies with the transformational message strategy markedly enhances their effectiveness.Practical implicationsUseful managerial guidance to develop effective message strategies is offered. In particular, the importance of transformational messages, both as a standalone and a complementary message strategy, is underscored. By mastering and deploying transformational messages more frequently in their social media communication, marketers could improve their effectiveness.Originality/valueDrawing on a theory-driven typology, this study sheds light on how message strategy shapes consumer behavioral engagement in a social media context. Importantly, the study documents pioneering empirical evidence regarding the effect of combined message strategies on consumer behavioral engagement.
