Impact of quality management practices on change readiness due to new quality implementations
Authors: Uluskan Meryem , McCreery John K. , Rothenberg Lori
Published: July 2018

Purpose

Implementing new quality initiatives in organizations is challenging, as it requires managers and employees to adjust to new processes, methodologies and even mindsets. The purpose of this study is to investigate the relationship between quality management (QM) practices and readiness for change due to implementing new quality initiatives such as lean, six sigma and to determine which dimensions of QM are more important to change efficacy and change commitment.

Design/methodology/approach

The issues are examined in this study through the analysis of survey data obtained from US textile and apparel industry managers by using factor analysis, stepwise regression to construct path model and structural equation modeling.

Findings

This study identifies change readiness measures which are specific for quality implementations and establishes two constructs, namely, change commitment and change efficacy. The results indicate that as good Employee Relations increase, the level of organizational change commitment increases. If employees are engaged and empowered to provide excellent quality, then it is more likely that they will be committed to change due to implementing future quality initiatives. Moreover, a direct relationship between Customer Relationship Management and change efficacy is found. Companies with a strong customer orientation are more able to implement the quality initiatives that matter to their markets.

Originality/value

This study is unique in investigating the empirical relationship between QM practices and the dimensions of readiness for change due to implementing new quality initiatives via data from various organizations. This study empirically contributes to the QM literature with change readiness antecedents in quality implementation setting.

Authors: Narayanamurthy Gopalakrishnan , Gurumurthy Anand , Lankayil Arjun Athikkamannil
Published: July 2018

Purpose

The purpose of this study is to document the experience and impact of implementing lean thinking (LT) in an Indian healthcare institution.

Design/methodology/approach

A detailed review of literature documenting the experience of implementing LT in healthcare institutions is carried out. Review revealed that there is a dearth of documentation on implementation of LT in Indian healthcare institutions. To address this gap, the experience of implementing LT in an Indian case hospital is documented by adopting a single case study research methodology.

Findings

Lean practices adopted by the Indian case hospital are documented. Performance measures before and after implementation of lean practices in the case hospital are compared. Based on this experience, a framework for implementing LT is proposed for healthcare institutions.

Research limitations/implications

The current study documents the experience of an Indian case hospital, which is only at its initial stages of LT implementation. Future studies can be undertaken to assess the long-term impact of implementing LT in a healthcare institution. Similarly, the proposed framework for implementing LT can be validated by using the same in different healthcare institutions.

Practical implications

Review of lean principles, practices and performance measures discussed in the literature on implementing LT in healthcare institutions can act as a ready reckoner for practitioners. Framework proposed based on the experience of the case hospital is expected to guide healthcare practitioners in their lean journey.

Originality/value

This study is unique, as it documents the experience of implementing LT in an Indian healthcare institution and proposes a framework for implementing LT for future validation.
Wettability of laser textured surface: a parametric study based on numerical simulation and experimentation
Authors: Jiao Yunlong , Liu Xiaojun , Liu Kun
Published: July 2018

Purpose

Dynamic spreading and wetting on the rough surfaces is complicated, which directly affects the fluxion and phrase transition properties of the fluid. This paper aims to enhance our knowledge of the mechanism of micro-texture lubrication from interface wettability and provide some guidance for the practical manufacturing of the surfaces with special wettability and better lubrication characteristics.

Design/methodology/approach

The effect of surface topography on the wetting behavior of both smooth and rough hydrophilic surfaces was investigated using a combination of experimental and simulation approaches. Four types of patterns with different topographies were designed and fabricated through laser surface texturing. The samples were measured with a non-contact three-Dimensional (3D) optical profiler and were parameterized based on ISO 25178. Quantitative research on the relevancy between the topography characteristic and wettability was conducted with several 3D topography parameters.

Findings

Results show that for the surfaces with isotropic textures, topography with a small skewness (Ssk) and a large kurtosis (Sku) exhibits better wettability and spreading behavior. For the surfaces with anisotropic textures (smaller texture aspect ratio,Str), dominant textures (such as long groove, rectangle) play a significant guiding role in promoting spreading. In addition, the moving mechanism of the triple contact line and anisotropic spreading were also studied using a computational fluid dynamics simulation. The simulation results have a good adherence with the experimental results.

Originality/value

Most of the surface characterization methods at present remain at a level that is related to geometric description, and the topography parameters are limited to 2D roughness parameters. So in present study, the relevancy between wettability and 3D surface topography parameters is explored. The authors believe that the current work provides a new viewpoint to the relevancy between surface topography and wettability.
Tribological properties of nanometer Al2O3 and nanometer ZnO as additives in lithium-based grease
Authors: He Qiang , Wang Zhigang , Li Anling , Guo Yachen , Liu Songfeng
Published: July 2018

Purpose

Nanoparticles as the grease additives play an important role in anti-wear and friction-reducing property during the mechanical operation. To improve the lubrication action of grease, the tribological behavior of lithium-based greases with single (nanometer Al2O3 or nanometer ZnO) and composite additives (Al2O3–ZnO nanoparticles) were investigated in this paper.

Design/methodology/approach

The morphology and microstructure of nanoparticles were characterized by means of transmission electron microscope and X-ray diffraction. Tribological properties of different nanoparticles as additives in lithium-based greases were evaluated using a universal friction and wear testing machine. In addition, the friction coefficient (COF) and wear scar diameter were analyzed. The surface morphology and element overlay of the worn steel surface were analyzed by scanning electron microscopy (SEM) and energy dispersive spectrometer (EDS), respectively.

Findings

The results show that the greases with nanometer Al2O3 or nanometer ZnO and the composite nanoparticles additives both exhibit lower COFs and wear scar diameters than those of base grease. And the grease with Al2O3–ZnO composite nanoparticles possesses much lower COF and shows much better wear resistance than greases with single additives. When the additives contents are 0.4 Wt.% Al2O3 and 0.6 Wt.% ZnO, the composite nanoparticles-based grease exhibits the lowest mean COF (0.04) and wear scar diameter (0.65 mm), which is about 160% and 28% lower than those of base grease, respectively.

Originality/value

The main innovative thought of this work lies in dealing with the grease using single or composite nanoparticles. And through a serial contrast experiments, the anti-wear and friction-reducing property with different nanoparticles additives in lithium grease are evaluated.
An online de-noising method for oil ultrasonic wear debris signal: fuzzy morphology component analysis
Authors: Li Yining , Zhang Peilin
Published: July 2018

Purpose

In real working condition, signal is highly disturbed and even drowned by noise, which extremely interferes in detecting results. Therefore, this paper aims to provide an effective de-noising method for the debris particle in lubricant so that the ultrasonic technique can be applied to the online debris particle detection.

Design/methodology/approach

For completing the online ultrasonic monitoring of oil wear debris, the research is made on some selected wear debris signals. It applies morphology component analysis (MCA) theory to de-noise signals. To overcome the potential weakness of MCA threshold process, it proposes fuzzy morphology component analysis (FMCA) by fuzzy threshold function.

Findings

According to simulated and experimental results, it eliminates most of the wear debris signal noises by using FMCA through the signal comparison. According to the comparison of simulation evaluation index, it has highest signal noise ratio, smallest root mean square error and largest similarity factor.

Research limitations/implications

The rapid movement of the debris particles, as well as the lubricant temperature, may influence the measuring signals. Researchers are encouraged to solve these problems further.

Practical implications

This paper includes implications for the improvement in the online debris detection and the development of the ultrasonic technique applied in online debris detection.

Originality value

This paper provides a promising way of applying the MCA theory to de-noise signals. To avoid the potential weakness of the MCA threshold process, it proposes FMCA through fuzzy threshold function. The FMCA method has great obvious advantage in de-noising wear debris signals. It lays the foundation for online ultrasonic monitoring of lubrication wear debris.
Technology implementation in delivery of healthcare to older people: how can the least voiced in society be heard?
Authors: van Zaalen Yvonne , McDonnell Mary , Mikołajczyk Barbara , Buttigieg Sandra , Requena Maria del Carmen , Holtkamp Fred
Published: July 2018

Purpose

The purpose of this paper is to focus on ethical and judicial themes related to technology and the older adults.

Design/methodology/approach

Different consecutive phases in technology design and allocation will be discussed from a range of perspectives.

Findings

Longevity is one of the greatest achievements of contemporary science and a result of development of social relations. Currently, various non-communicable diseases affect older adults and impose the greatest burden on global health. There is a great emphasis across Europe on caring for the older person in their own homes. Technology has a mediating role in determining the possibilities for good quality of life (QOL). The concept of assisting the older adult through the use of technology so as to access healthcare services has enormous potential. Although the potential of technology in healthcare is widely recognised, technology use can have its downsides. Professionals need to be aware of the risks, namely, those related to the privacy of the older person, which may accompany technology use.

Research limitations/implications

By 2050, there will be more people aged over 65 than there are children. This phenomenon of global ageing constitutes a massive challenge in the area of health protection.

Practical implications

Professionals need to be aware of the risks, for example, related to the privacy of the older person, that may accompany technology use.

Social implications

There is a great emphasis across Europe on caring for the older person in their own homes. Technology has a mediating role in determining the possibilities for QOL.

Originality/value

The concept of assisting the older adult through the use of technology to avail of healthcare has enormous potential. Assistive technology, social media use and augmentative and alternative communication can have a positive effect on the QOL of older people, as long as they are supported enough in use of these technologies. However, ethical and juridical considerations are at stake as well.
A systematic model for improving theoretical garment fit
Authors: Hernández Niina , Mattila Heikki , Berglin Lena
Published: July 2018

Purpose

The purpose of this paper is to use a systematic model for detecting misfit between the garment and the target group.

Design/methodology/approach

Using an empirical–analytical methodology, the systematic model was tested. The input data were run through the model to generate the output data, which were analysed, including basic statistics. The purpose of the analysis was to detect misfit and improve the garment measurement chart. This procedure was repeated until a clear result was reached.

Findings

The result of this study is an optimised garment measurement chart, which considers the garment’s ease, different sizes/proportions in relation to a target group. The results show that it is possible to use a systematic model to define the shortcomings of a garment´s range of sizes and proportions.

Research limitations/implications

Further studies are needed to verify the results of the theoretical garment fit and their values in relation to real garment fit.

Practical implications

If the systematic model is implemented to improve the theoretical garment fit, this may have effects on the available garment sizes and its proportions, resulting in increased theoretical garment fit for the target group.

Originality/value

The paper presents a systematic model for detecting and eliminating theoretical fitting; the model includes both garment ease allowance and defined points of misfit.
An empirical exploration of TQM, TPM and their integration from Indian manufacturing industry
Authors: Sahoo Saumyaranjan
Published: July 2018

Purpose

The purpose of this paper is to comparatively assess the contributions of total quality management (TQM) and total productive maintenance (TPM) practices, exclusively and collectively, on manufacturing business performance.

Design/methodology/approach

Responses to survey questionnaires were collected using multiple modes of data collection. A total of 269 filled responses were collected and analyzed to ascertain the contribution made by exclusive and collective implementation of TQM and TPM practices on business performance. The respondent firms were grouped into three clusters based on early, in-transition and advanced stages of implementation of either or both TQM and TPM manufacturing practices. Comparative assessment of the impact of standalone TQM, standalone TPM and combined TQM–TPM manufacturing methods on business performance parameters have been evaluated using statistical tools within each cluster.

Findings

Evidences were found to support the supposition that integrated implementation of both TQM and TPM practices over a reasonable period of time contributes in delivering better business performance as compared to the standalone implementation strategy.

Research limitations/implications

The study has its own limitations because of its chosen research approach. As the data in this study were collected from production management personnel on the basis of their subjective evaluations, more comprehensive objective performance indicators shall be employed for comparative assessment of manufacturing practices in future studies. In-depth case studies are needed to further validate the findings of the research study.

Practical implications

The analytical results reveal that an integrated TQM–TPM strategic implementation can systematically contribute toward realization of significant improvement in manufacturing business performance parameters. The results of this study are vital for production managers and senior management personnel of manufacturing firms that have implemented TQM and are considering introducing TPM in their organization (or vice-versa).

Originality/value

This empirical study signifies the need for strategically aligning and managing various production improvement ideologies for realization of an organization’s growth and sustainability in a long run. In particular, this paper invigorates the discussion about improving the synergy between maintenance and quality functions in the organization for meeting the challenges of highly competitive market environment.
Inventory leanness, risk taking, environmental complexity, and productivity
Authors: Zhu Xuechang , Yuan Qigang , Zhang Wei
Published: July 2018

Purpose

The purpose of this paper is to examine the effect of inventory leanness on productivity. In particular, the authors explore the moderating role of environmental complexity and the mediating role of risk taking.

Design/methodology/approach

In the mediated moderation analysis of the relationship among inventory leanness, risk taking, environmental complexity and productivity, the authors adopt the instrumental variable method to test the hypotheses based on data collected from 1,709 Chinese listed manufacturing firms.

Findings

The results show that there is an inverted U-shaped relationship between inventory leanness and productivity. The authors then demonstrate the role of risk taking in mediating this relationship. Furthermore, the authors find that environmental complexity not only negatively moderates the relationship between inventory leanness and productivity, but also negatively moderates the relationship between risk taking and productivity.

Practical implications

Managers should not be excessively pursuing inventory leanness improvements, so as not to damage the ability to increase productivity.

Originality/value

This paper may be the first study to empirically demonstrate the moderating effect of environmental complexity and the mediating effect of risk taking on the inverted U-shaped relationship between inventory leanness and productivity.
Validation of qualitative aspects of the Lean Assessment Tool (LAT)
Authors: Pakdil Fatma , Toktaş Pelin , Leonard Karen Moustafa
Published: July 2018

Purpose

The purpose of this paper is to test the reliability and validity of the qualitative section of Lean Assessment Tool (LAT) starting from the point where a reliable and valid tool is needed to measure increasing leanness level of business organizations.

Design/methodology/approach

The questionnaire used in this study included the qualitative component of LAT developed by Pakdil and Leonard (2014). The unit of the study was individual employees who work in manufacturing firms participating in this study. This study focused on the data collected from three firms that operate in Turkey and two firms that operate in the USA. The total respondents from Turkish firms were 263 employees, while the 205 employees responded from US firms.

Findings

Exploratory factor analysis and confirmatory factor analysis were completed to determine valid and reliable factors that compose LAT’s qualitative component. The statistical analysis showed five distinct factors, namely process, delivery, quality, customer satisfaction and human resource. In addition, the fuzzy logic showed appropriate loadings to make the argument for its use in analysis of the LAT.

Research limitations/implications

This study moves the debate about the success or failure of lean efforts forward. With the debates about lean and its potential, it is necessary to have a scientific determination of success and the areas where further work in the firm is needed. Such measurement is the backbone of management progress, and the authors believe that this paper is useful. Second, the necessity of reliable and valid tools of lean assessment is obvious in the literature and practice. The findings of this study help academicians find reliable and valid tools to measure lean success both in the literature and practice.

Practical implications

Managerial implications include the development of a way to assess the areas of success and areas requiring further work. Failure to measure success and needs for further work has been the reason for the questionable results found in investigating lean implementation efforts. If there is no way to determine what is needed to improve lean efforts, they will be seen as failure, even if part of the implementation has been successful. This tool has been found to be potentially useful for evaluation of these crucial and time-consuming efforts.

Originality/value

In this study, the qualitative section of LAT has been validated. The results demonstrated that, based on two countries’ data sets, the scale was found to be reliable and valid within itself and across sociocultural boundaries.
A game theory application of a cruise value chain – the case of China
Authors: Wang Grace W.Y. , Zeng Qingcheng , Qu Chenrui , Mileski Joan
Published: July 2018

Purpose

Regardless of the facts showing a booming Chinese cruise market, cruise operations in China are very different from the current practices of the two major cruise markets – the US and the Mediterranean Sea. This study aims to quantify pricing strategies and possible incentive mechanisms of cruise operations in China.

Design/methodology/approach

Using optimization in economic-based game theory, the complexity of the pricing strategies and interaction and/or possible coordination within the cruise value-added chain can be captured.

Findings

The results show that a coordinative pricing strategy with Shapley profit redistribution within the value-added chain offers benefits to both cruise passengers and service suppliers. With two subsidy scenarios, one to the passenger and the other to the travel agent, a cooperative pricing strategy outperforms other strategies and successfully increases market shares and total revenue.

Originality/value

The advantages of coordination between participants in cruise value chain are quantified. Effective strategies for attracting players participating in cruise value chain are designed. This paper will provide market participants with strategies to enhance their decision-making processes.
Fad and fashion? The relevance of subjective performance measures
Authors: Demartini Maria Chiara , Trucco Sara
Published: July 2018

Purpose

The purpose of this paper is to investigate the effect of the use of subjective (objective) performance measures on relevant organisational outcomes, namely perceived managerial discretion (PMD) and manager’s satisfaction with the performance measurement system (PMS). Furthermore, the paper analyses the indirect link between subjective vs objective measures and managers’ satisfaction through PMD.

Design/methodology/approach

To test the research hypotheses, a paper-based questionnaire was sent to Italian health care managers in Lombardy. Thus, a PLS-SEM analysis was performed on a data set of 97 Italian health care managers.

Findings

Empirical findings showed that objective measures are more capable of supporting the managerial perception of discretion when compared to more subjective ones such as “fads” and “fashions”, and that managers are more satisfied with the PMS when it is grounded on objective measures rather than subjective ones.

Originality/value

The paper operationalizes and empirically tests the measure of PMD, linking this to antecedents and consequences. It also extends the literature on subjectivity in the PMS, since it develops new knowledge on the choice between subjective and objective measures by applying this choice to a variety of PMS, whereas prior literature on objective vs subjective measures has mainly focussed on performance evaluation.
Implementation of green supplier development process model in Indian automobile industry
Authors: Thakker Shivangi Viral , Rane Santosh B.
Published: July 2018

Purpose

The purpose of this paper is to develop a green supplier development (GSD) process model and validate the model with a case study in Indian automobile industry.

Design/methodology/approach

A literature survey of peer-reviewed journal articles, survey reports and paradigmatic books with managerial impact is done for the research. The process of GSD is modeled using stage-gate approach and KPIV and KPOV of the process are determined. The process model is implemented in an Indian automobile components manufacturing industry for validation.

Findings

The industry implemented the model with ten suppliers and was able to successfully convert seven of them into Green suppliers. Remaining three suppliers were asked to repeat the process again or terminate the contracts. Model implementation took around three years starting from planning of resources and finances to actual development of suppliers.

Research limitations/implications

The model implementation was done with a small automobile industry and hence the validation and implications may be generalized by taking the case study further in different industries. It would be beneficial to test the model with case studies of large-scale industries.

Practical implications

The process model for implementing GSD activities will help managers in taking complex investment decisions. The stages and process inputs and outputs are clearly defined which helps the managers to successfully develop the suppliers.

Originality/value

This paper puts forward the process model that should be implemented for the successful development of green suppliers. It might represent new opportunities for rigorous and relevant research in the area of green supply chain.
Internationalizing teacher education curricula: opportunities for academic staff development
Authors: Lourenço Mónica
Published: July 2018

Purpose

The purpose of this study is to understand the impact of a collaborative workshop, aimed to support teacher educators in embedding a “global outlook” in the curriculum on their perceived professional development.

Design/methodology/approach

The workshop included working sessions, during a period of 13 months, and was structured as participatory action research, according to which volunteer academics designed, developed and evaluated global education projects in their course units. Data were gathered through a focus group session, conducted with the teacher educators at a final stage of the workshop, and analyzed according to the principles of thematic analysis.

Findings

Results of the analysis suggest that the workshop presented a meaningful opportunity for teacher educators to reconstruct their knowledge and teaching practice to (re)discover the importance of collaborative work and to assume new commitments to themselves and to others.

Originality/value

The study addresses a gap in the existing literature on academic staff development in internationalization of the curriculum, focusing on the perceptions of teacher educators’, whose voices have been largely silent in research in the field. The study concludes with a set of recommendations for a professional development program in internationalization of the curriculum.
The “silent assassin” in your organization? Can job insecurity climate erode the beneficial effect of a high-quality leader-member exchange?
Authors: Nikolova Irina , Van der Heijden Beatrice , Låstad Lena , Notelaers Guy
Published: July 2018

Purpose

The purpose of this paper is to examine the possible role of job insecurity climate as a moderator in the relationship between leader–member exchange (LMX) and organizational citizenship behaviors (OCBs).

Design/methodology/approach

Questionnaire data were collected from 466 employees working in 14 organizations from both the private and public sector. Following the core tenets of social exchange theory and occupational stress theories, the authors argue that ideally job insecurity is studied as a climate-level construct, given the fact that intra-group social exchange processes strongly influence the formation of employee perceptions about specific aspects of their work context (e.g. job insecurity).

Findings

In line with one of the hypotheses, multi-level analyses revealed that LMX is significantly and positively related to OCBs. In addition, the authors found support for a negative moderation effect, such that LMX has a less strongly positive relationship with extra-role behaviors that are beneficial to the organization when job insecurity climate is high.

Originality/value

The study contributes to the limited empirical scholarly research on job insecurity climate and its correlates. Management and HR professionals in working organizations are advised to focus on preventive measures (e.g. to invest in the professional development of their employees, that is focus on employability enhancement, in order to reduce job insecurity) as well as on participation-based interventions.
Public accountability reform in a Nigerian ministry
Authors: Sulu-Gambari Waziri , Stafford Anne , Stapleton Pamela
Published: July 2018

Purpose

This paper aims to address the gap within the public accountability literature with regard to emerging economies and add to knowledge about how accountability is understood and how it plays out in practice in the context of public sector reform. While prior literature has focussed on the resource dependence of emerging nations, this paper examines the practice of public accountability in a non-resource-dependent emerging economy.

Design/methodology/approach

In a non-resource-dependent nation, we used a framework based on institutional theory but also draw upon the notion that international financial institutions act in an imperialist way to maintain their relationship with the country. The paper develops a concept of subtle coercion to explain the findings in relation to public accountability reform. The paper examines three reforms introduced and partially implemented in Nigeria: a local initiative that fits well with local understandings of what public accountability is and two imported initiatives that rely upon Western notions of accountability. The research method is a qualitative case study.

Findings

The paper reveals the ways in which accountability reform is complex and subtle. Local understanding of what accountability is led to perceptions that a locally designed reform had enjoyed some success, even though by its own admission Nigeria’s public sector still has a long distance to travel in terms of international notions of public accountability.

Research limitations/implications

The research is based in a single country which allows for in-depth study but limits the ability to generalise findings.

Originality/value

This case shows that specific and dynamic features of the political and economic environment can influence the nature of public accountability reform in a way which is not predictable or linear.
Calibration of rotating 2D LIDAR based on simple plane measurement
Authors: Gao Zhe , Huang Jun , Yang Xiaofei , An Ping
Published: July 2018

Purpose

This paper aims to calibrate the mounted parameters between the LIDAR and the motor in a low-cost 3D LIDAR device. It proposes the model of the aimed 3D LIDAR device and analyzes the influence of all mounted parameters. The study aims to find a way more accurate and simple to calibrate those mounted parameters.

Design/methodology/approach

This method minimizes the coplanarity and area of the plane scanned to estimate the mounted parameters. Within the method, the authors build different cost function for rotation parameters and translation parameters; thus, the parameter estimation problem of 4-degree-of-freedom (DOF) is decoupled into 2-DOF estimation problem, achieving the calibration of these two types of parameters.

Findings

This paper proposes a calibration method for accurately estimating the mounted parameters between a 2D LIDAR and rotating platform, which realizes the estimation of 2-DOF rotation parameters and 2-DOF translation parameters without additional hardware.

Originality/value

Unlike previous plane-based calibration techniques, the main advantage of the proposed method is that the algorithm can estimate the most and more accurate parameters with no more hardware.
City life on fast lanes: Urbanization induces an evolutionary shift towards a faster lifestyle in the water flea Daphnia
Authors: Brans Kristien I. , De Meester Luc
Published: July 2018

Multiple species show significant trait shifts in response to urbanization. Yet, the impact of anthropogenic warming linked to the urban heat island effect is remarkably understudied. In addition, the relative contributions of phenotypic plasticity and genetic change underlying trait shifts in response to urbanization are poorly known.

A common garden study with the water flea Daphnia magna revealed that both genetic differentiation in response to urbanization and phenotypic plasticity in response to higher rearing temperature (24°C) induced significant parallel multivariate shifts in life‐history strategy along the slow–fast pace‐of‐life axis.

Urban animals and animals reared at higher temperatures are characterized by fast maturation, early release of progeny, a smaller size at maturity, increased fecundity and higher performance (given by maximal population growth rate “r”) compared to genotypes isolated from rural ponds and animals reared at lower temperatures, respectively.

Evolution in response to urbanization accounted for 30% of the total observed shift in life history and caused a significant change in mean trait values, while plasticity responses to experimental warming were unaltered between urban and rural populations. The total trait change achieved through both plasticity and evolution ranged from 8% to 56% depending on the trait.

Our results provide clear evidence for evolution underlying an increase in pace of life of populations in response to urbanization. Given the pivotal role of Daphnia in aquatic ecosystems, this shift potentially feeds back to population structure, top‐down control of algae and food web dynamics in urban freshwater ecosystems. In addition, we argue that adaptation to urban heat islands might render these populations preadapted in a context of future climate change.

Attenuation mechanisms in fractured fluid‐saturated porous rocks: a numerical modelling study
Authors: Caspari Eva , Novikov Mikhail , Lisitsa Vadim , Barbosa Nicolás D. , Quintal Beatriz , Rubino J. Germán , Holliger Klaus
Published: July 2018

Seismic attenuation mechanisms receive increasing attention for the characterization of fractured formations because of their inherent sensitivity to the hydraulic and elastic properties of the probed media. Attenuation has been successfully inferred from seismic data in the past, but linking these estimates to intrinsic rock physical properties remains challenging. A reason for these difficulties in fluid‐saturated fractured porous media is that several mechanisms can cause attenuation and may interfere with each other. These mechanisms notably comprise pressure diffusion phenomena and dynamic effects, such as scattering, as well as Biot's so‐called intrinsic attenuation mechanism. Understanding the interplay between these mechanisms is therefore an essential step for estimating fracture properties from seismic measurements. In order to do this, we perform a comparative study involving wave propagation modelling in a transmission set‐up based on Biot's low‐frequency dynamic equations and numerical upscaling based on Biot's consolidation equations. The former captures all aforementioned attenuation mechanisms and their interference, whereas the latter only accounts for pressure diffusion phenomena. A comparison of the results from both methods therefore allows to distinguish between dynamic and pressure diffusion phenomena and to shed light on their interference. To this end, we consider a range of canonical models with randomly distributed vertical and/or horizontal fractures. We observe that scattering attenuation strongly interferes with pressure diffusion phenomena, since the latter affect the elastic contrasts between fractures and their embedding background. Our results also demonstrate that it is essential to account for amplitude reductions due to transmission losses to allow for an adequate estimation of the intrinsic attenuation of fractured media. The effects of Biot's intrinsic mechanism are rather small for the models considered in this study.
Riparian reserves help protect forest bird communities in oil palm dominated landscapes
Authors: Mitchell Simon L. , Edwards David P. , Bernard Henry , Coomes David , Jucker Tommaso , Davies Zoe G. , Struebig Matthew J.
Published: July 2018

Conversion of forest to oil palm agriculture is a significant and ongoing threat to tropical biodiversity. Despite this, little is known about the value of riparian reserves in oil palm and how these conservation set‐asides might best be managed to maintain biodiversity.

We characterized bird communities of 28 sites in an oil palm‐forest mosaic in Sabah, Malaysia using 6,104 encounters from 840 point counts. Sites included oil palm riparian reserves of various vegetation quality and reserve widths, which were compared to oil palm streams without a riparian reserve as well as riparian and nonriparian control areas in continuous logged forest.

Riparian reserves, oil palm waterways, and control sites in riparian and nonriparian forest supported distinct avifaunal communities. Riparian reserve width, forest quality, and amount of forest cover were the strongest predictors of bird species richness. For forest‐dependent species, each of these predictors had a stronger effect size when compared with all species. On average, reserves held 31% of all species and 30% of forest specialists, whereas riparian forest controls averaged 32% of all species, but 38% of forest species.

Riparian reserves with >40 m of natural vegetation on each bank supported similar bird diversity to riparian forest control habitats found in continuous forest. However, to support equivalent numbers of forest‐dependent species and species of conservation concern, reserves would need to be at least 100‐m wide on each bank. The largest numbers of species were found in riparian reserves with above‐ground carbon densities exceeding 75 tC/ha, highlighting the importance of forest quality, as well as width, in supporting riparian bird communities.

Synthesis and applications. If designed and protected appropriately, riparian reserves in oil palm estates support diverse bird communities, including many species of conservation concern. This can be achieved by designating large reserves (80–200 m total width). But, to maximize species numbers, forest disturbance should also be minimized prior to conversion as well as during plantation operations.
The Material Constitution
Authors: Goldoni Marco , Wilkinson Michael A.
Published: July 2018

What is the material context of constitutional order? The purpose of this paper is to offer an answer to that question by sketching a theory of the material constitution. Moving beyond the interwar constitutional theories of Heller and Mortati, the paper outlines the four ordering forces of the material constitution: political unity; a set of institutions; social relations, and fundamental political objectives. These forces constitute the substance and dynamic of constitutional ordering, in internal relation with the formal constitution. Because these ordering forces are multiple, and in tension with one another, there is no single determining factor of constitutional development. Neither is order as such guaranteed. The conflict that characterises the modern human condition might but need not be internalised by the process of constitutional ordering. The theory of the material constitution offers an account of the basic elements of this process as well as its internal dynamic.
Equality Law and the Protected Characteristics
Authors: Malleson Kate
Published: July 2018

UK anti‐discrimination law is founded on a grounds‐based system of protected characteristics. For this system to function as a legitimate and workable legal framework the characteristics must satisfy three conditions: they must have some definitional and categorical stability, they must broadly reflect people's understanding of social reality and lived experiences and they must align with the most significant axes of discrimination in society. This article argues that all three conditions are becoming increasingly difficult to satisfy as a result of dramatic shifts in social configurations of identity and the ongoing failure to include socio‐economic status as a legally protected characteristic. The future of the legislative framework may depend on the willingness of courts and policy‐makers to adopt a more context‐based approach to the protected characteristics. This would require them to interrogate claims of individual instances of discrimination in the context of wider, but also more particular substantive group disadvantage.
Testing Times Ahead: Non‐Invasive Prenatal Testing and the Kind of Community We Want to Be

This article reviews the Nuffield Council on Bioethics’ report on Non‐Invasive Prenatal Testing (NIPT); and introduces two general questions provoked by the report – concerning, respectively, the nature and extent of the informational interests that are to be recognised in today's ‘information societies’ and the membership of today's ‘genetic societies’. The article also considers the role and nature of the Nuffield Council. While the Council's report identifies a range of individual and collective interests that are relevant to determining the legitimate uses of NIPT, we argue that it should put these interests into an order of importance; we sketch how this might be done; and we suggest that, failing such a prioritisation of interests, the Council should present its reflections in a way that engages public debate around a number of options rather than making firm recommendations.

Communicating to publics at risk can be challenging for spokespersons during crises. Knowing what content to include in such messages can be instrumental in achieving effective behavioural results among disparate publics and may differ across cultures. Whereas the IDEA model has demonstrated itself to be an effective framework for designing instructional risk and crisis messages in the United States, this study builds on the conclusions drawn previously by examining the model's utility in Sweden. Results of the experiment confirm that messages constructed according to the IDEA model are effective in Sweden's state‐oriented risk culture, as well. Future research should focus on the model's utility for various risk and crisis types among both Swedish populations and populations in additional countries.
The utility of mortality hazard rates in population analyses

Mortality is a key process in ecology and evolution, and much effort is spent on development and application of statistical and theoretical models involving mortality. Mortality takes place in continuous time, and a fundamental representation of mortality risks is the mortality hazard rate, which is the intensity of deadly events that an individual is exposed to at any point in time. In discrete‐time population models, however, the mortality process is represented by survival or mortality probabilities, which are aggregate functions of the mortality hazard rates within given intervals. In this commentary, we argue that focussing on mortality hazard rates, also when using discrete‐time models, aids the construction of biologically reasonable models and improves ecological inference.

We discuss three topics in population ecology where mortality hazard rates can be particularly useful for biological inference, but are nevertheless often not used: (a) modelling of covariate effects, (b) modelling of multiple sources of mortality and competing risks, and (c) elasticity analyses of population growth rate with respect to demographic parameters. To facilitate estimation of cause‐specific mortality hazard rates, we provide extensions to the R packagemarked.

Using mortality hazard rates sometimes makes it easier to formulate biologically reasonable models with more directly interpretable parameterizations and more explicit assumptions. In particular, interpretations about relative differences between mortality hazard rates, or effects of relative changes in mortality hazard rates on population growth (elasticities), are often more meaningful than interpretations involving relative differences in survival (or mortality) probabilities or odds.

The concept of hazard rates is essential for understanding ecological and evolutionary processes and we give an intuitive explanation for this, using several examples. We provide some practical guidelines and suggestions for further methods developments.
Changing International Financial Architecture: Growing Chinese Influence?
Authors: Ito Takatoshi
Published: July 2018

It is often said that the 21st century will be the Asian century. Based on population and gross domestic product projections, it certainly looks as if this will be so. Will the existing international financial institutions give more voices, votes, and top positions to Asia? Or will Asia create its own institutions that would rival the old architecture? This present paper argues, first, that China, and possibly India, will be in a position to be so influential that the international financial architecture may have to go through significant changes. Second, the three large crises in the last 20 years have made Asian countries more confident that they can manage capital flows by accumulating large foreign reserves and by adopting sound macrofinancial policies. After 2009, China started to push various initiatives that will amount to creating its own sphere of influence with new regional institutions in the future.
Is China’s Development Finance a Challenge to the International Order?
Authors: Dollar David
Published: July 2018

China is a major funder of developing country infrastructure, lending $40 billion annually through policy banks. Lending does not favor the belt and road above other regions. China’s lending is indifferent to risk, that is, it is uncorrelated with indices of political stability and rule of law. Some major borrowers with poor governance are beginning to have debt sustainability problems, while other borrowers are in good fiscal shape. Chinese banks have been reluctant to follow global environmental norms but seem to be evolving in that direction. Chinese actions seem more a revision of the global system than a challenge to it.
