Authors: Hu Mingwei , Wang Hongguang , Pan Xinan , Tian Yong 
Published: August 2019

Purpose
The purpose of this paper is to search the optimal arrangement scheme of random motion accuracy of joints for optimal synthesis of pose repeatability which can make robot design more reasonable and reduce the development cost of robots.

Design/methodology/approach
In this paper, a mathematical model of pose repeatability, which includes positioning repeatability and orientation repeatability of robots, is established. According to the ISO 9283 standard, an optimal synthesis method of pose repeatability for collaborative robots is introduced, and three optimization objective functions are proposed. The optimization model is solved by using numerical analysis software, and the optimal arrangement scheme of random motion accuracy of joints is obtained which meets the requirements of pose repeatability of robot.

Findings
It is found that, in three optimization objective functions, the single-objective evaluation function of maximization of joint motion error is more suitable for optimal synthesis of pose repeatability. In practice, due to the safety factor, the test results of pose repeatability are better than the results of optimal synthesis of pose repeatability.

Practical implications
This method makes robot design more reasonable and reduces the development cost of robots.

Originality/value
This work is the first time to optimize the orientation repeatability of collaborative robots. Because the pose repeatability of most robots is tested by the ISO 9283 standard, so this method which is based on this standard is more suitable for the performance requirements of robot products.
Sustaining family-firm innovation through value and process principles
Authors: Lattuch Frank 
Published: August 2019

Purpose
Organization renewal through innovation represents a difficult managerial challenge in family firms. This paper aims to reveal a framework for sustaining innovation capabilities through a perspective of value and process principles.

Design/methodology/approach
The author examined the findings from consulting projects in high performing family firms and literature from the areas of family firm strategy and leadership.

Findings
The author describes how combining patterns of innovative organizations with patterns of high-performing family firms can help leaders to sustain innovation. This study indicates that a value- and process-driven perspective is important for effective innovation. In particular, the four value principles are continuity-, community-, connection- and command-related factors (4C’s). The four process principles, in turn, are profession-, project-, product- and purchase-related factors (4P’s).

Originality/value
This paper is a part of a wider study of innovative German family firms initiated in 2012. The 4C’s and 4P’s framework suggests a practical means to better implement innovation by reconciling the firm’s innovation strategy, leadership behavior and organizational learning.
Corporate culture and stock returns: evidence from Indian companies
Authors: Aziz Tariq , Ansari Valeed Ahmad , Alam Mahfooz 
Published: August 2019

Purpose
The purpose of this paper is to investigate the stock market performance of companies featured in the survey “Best Companies to Work For” as a proxy for corporate culture.

Design/methodology/approach
The authors employed the portfolio formation and event study methods from finance to examine the linkage between corporate culture and future stocks returns. The lists of India’s best place to work for by Great Place to Work® Institute and Business Today (BT), India’s leading business magazine, form the primary surrogate for a great corporate culture. The authors compared the stock market performance of the culture portfolio vis-à-vis market index, in addition to using Carhart’s (1997) four-factor model.

Findings
A portfolio of Indian firms that featured in the “Best Companies to Work For” by Great Place to Work© Institute and BT magazine provides a higher return than the market index Sensex both on an ordinary return and on a risk-adjusted basis. The four-factor αs of the value-weighted culture portfolios are significant, implying that these portfolios have provided abnormal returns during the sample period. Moreover, the findings suggest a positive drift in the abnormal returns after inclusion in the “Best Companies to Work For” list.

Research limitations/implications
The results are largely in conformity with the prediction of the theory that states that corporate culture is an economic asset for a firm that increases its value.

Practical implications
From an investor’s point of view, the study indicates that investment in “Best Companies to Work For” is a better alternative than passive index investing.

Originality/value
This study fills the empirical void in the relationship between corporate culture and stock market performance in the Indian context.
Numerical investigation of high pressure turbine blade tip-shaping effects on the aerothermal and dynamic performance
Authors: Tong Fujuan , Gou Wenxuan , Li Lei , Yue Zhufeng , Gao Wenjing , Li Honglin 
Published: August 2019

PurposeIn order to improve the engine reliability and efficiency, an effective way is to reform the turbine blade tip conformation. The paper aims to discuss this issue.Design/methodology/approachThe present research provides several novel tip-shaping structures, which are considered to control the blade tip loss. Four different tip geometries have been studied: flat tip, squealer tip, flat tip with streamwise ribs and squealer tip with streamwise ribs. The tip heat transfer and leakage flow are both analyzed in detail, for example the tip heat transfer coefficient, tip flow and local pressure distributions.FindingsThe results show that the squealer seal and streamwise rib can reduce the tip heat transfer and leakage loss, especially for the squealer tip with streamwise ribs. The tip and near-tip flow patterns at the different locations of axial chord reflect that both the squealer seal and streamwise rib structure can control the tip leakage flow loss. In addition, the analysis of the aerodynamic parameters (the static pressure and turbine efficiency) also indicates that the squealer tip with streamwise ribs obtains the highest adiabatic efficiency with an increase of 2.34 percent, compared with that of the flat tip case.Originality/valueThe analysis of aerothermal and dynamic performance can provide a reference for the blade tip design and treatment.

Findings
The experiment was carried out based on the determined optimized structure, and the results showed that the fatigue life meets the design requirements.

Originality/value
This research has certain guiding significance for the design and developments of high-cycle fatigue force sensors.
Corporate sustainability disclosure’s importance in China: financial analysts’ perception
Authors: Zhang Jhunru , Djajadikerta Hadrian Geri , Trireksani Terri 
Published: August 2019

PurposeCorporate sustainability in China has become a subject of increasing international concern. Corporate sustainability disclosure (CSD) is considered a useful tool to facilitate the empowerment and acknowledgement of stakeholders in the quest for sustainability. However, the degree of cultural and political influences for being sustainably orientated can be significantly different between countries. This study aims to examine the perception of financial analysts, as CSD report users, in China about the level of importance of various indicators of corporate sustainability described in the Global Reporting Initiative (GRI) Sustainability Reporting Guidelines.Design/methodology/approachA set of questionnaires was developed based on GRI G4 guidelines to measure the perception of financial analysts in China on the level of importance of each sustainability indicator described in the GRI G4. A five-point Likert scale was used to measure the report users’ perceptions of each of the indicators.FindingsThe findings of this study increase our understanding of how Chinese CSD report users perceive corporate sustainability differently from the GRI guidelines. The main results show that the environmental aspect of sustainability was seen to be important in China, followed by the social and economic aspects. Indicator-wise, “water”, “effluents and waste”, “emissions”, “compliance” and “energy” were perceived as vital in the environmental category, while “customer health and safety”, “customer privacy” and “compliance” were considered significant in the social category.Originality/valueThis study addresses the need for differing corporate sustainability guidelines for different nations and cultures, specifically within the Chinese context. It also contributes to the corporate sustainability literature by adding to our understanding of how financial analysts in China, as CSD report users, perceive aspects of sustainability.
Clarifying absorptive capacity and dynamic capabilities dilemma in high dynamic market IT SMEs
Authors: Senivongse Chulatep , Bennet Alex , Mariano Stefania 
Published: August 2019

PurposeThe purpose of this study is to investigate absorptive capacity and dynamic capabilities dilemma in high dynamic market IT small medium enterprises (SMEs). Absorptive capacity and dynamic capabilities have a conflict in theoretical stance. Those in favor of dynamic capabilities regard absorptive capacity as a part of dynamic capabilities, and there are many arguments regarding treating absorptive capacity as a part of dynamic capabilities. One major deficit of dynamic capabilities is that it requires adjusting the firm’s dynamic resources when responding to change, requiring some investment and time. Thus, dynamic capabilities then have a problem in instantaneously responding to a highly dynamic market. With the requirement to adjust organizational resources, absorptive capacity, as a part of dynamic capabilities, cannot have direct impact on a firm’s performance.Design/methodology/approachTo show that absorptive capacity, by itself, can have a direct impact on a firm’s performance in a highly dynamic market, quantifiable variables are identified to measure the level of effort in developing absorptive capacity. The relationships between the absorptive capacity development effort and the firm’s financial performance is then explored and evaluated.FindingsIt is confirmed that absorptive capacity in a high dynamic market such as IT SMEs have direct and positive impact to the firm’s financial performance, without having to configure its resource to interact with changes.Originality/valueThe study discusses the paradoxical dilemma of the role of absorptive capacity under the light of dynamic capability. The finding indicates that in high dynamic market when the spontaneous respond to market change is crucial to firm's survival, absorptive capacity can direly deliver the result to leverage the firm's performance without having to reconfigure its resources as indicated in the theoretical stance of dynamic capability.
Preliminary analysis of crustal shear‐wave splitting in the Sanjiang lateral collision zone of the southeast margin of the Tibetan Plateau and its tectonic implications

Published: August 2019

ABSTRACTThe collision of the Indian and Eurasian plates, to the east of the eastern Himalayan syntaxes, forms the Sanjiang lateral collision zone in the southeast margin of the Tibetan Plateau, where there are intense crustal deformation, active faults, earthquakes, as well as a metallogenic belt. Given the lack of adequate seismic data, shear‐wave splitting in this area has not been studied. With seismic data from a temporary seismic linear array, as well as permanent seismic stations, this paper adopts the identification on microseismic event to pick more events and obtains shear‐wave splitting parameters from local earthquakes. From the west to the east, the study area can be divided into three subzones. The “fast” polarization (i.e. the polarization of the fast shear wave) varies gradually from NNW to NS to NNE in these three subzones. The time delay of the slow shear wave (i.e. the time difference between the two split shear waves) also increases in the same direction, indicating the presence of seismic anisotropy above 25 km in the crust. Both shear‐wave splitting parameters are closely related to stress, faults and tectonics. The scatter and the “dual” (i.e. two) dominant orientations of the fast polarizations at several stations indicate strong distortions caused by nearby faults or deep tectonics. The anisotropic parameters are found to be related to some degree to the metallogenic belt. It is worth to further analyse the link between the anisotropic pattern and the metallogenic area, which suggests that shear‐wave splitting could be applied to study metallogeny. This paper demonstrates that the identification on microseismic event is a useful tool in detecting shear‐wave splitting details and exploring its tectonic implications.
Causes and consequences of inverse density‐dependent territorial behaviour and aggression in a monogamous mammal

Published: August 2019

AbstractTerritoriality is an important process shaping population dynamics, and the defence of a territory is crucial for individuals to increase the duration of territory occupancy and, consequently, reproductive success. However, little is known about how the frequency of territory intrusions and subsequent territorial behaviours and aggression by territory owners are affected by external factors, such as population density. This is important because it can affect mate change (the replacement of one pair member) and dispersal, a key ecological process.The aim of this study was to investigate the behavioural and spatial response of territory owners to intruder pressure as a function of population density in a territorial, monogamous mammal, the Eurasian beaver (Castor fiber).Using a combination of GPS technology, scent experiments, camera trap data and tail scar observations from an individual‐based long‐term study, we investigated the factors influencing spatial movement patterns by territory owners in response to a simulated intruder and the factors affecting territory intrusions.We found consistent inverse density‐dependent patterns in territorial behaviours and evidence of conspecific aggression. At lower densities, territory owners detected more simulated intrusions, showed more territorial reactions and experienced increased conspecific aggression as indicated by tail scars, suggesting increased intruder pressure.Inverse density‐dependent territorial behaviour and aggression suggest a potential mechanistic link between inverse density‐dependent natal dispersal and mate change. At low population densities, increased dispersal amplifies intruder pressure, leading to the observed increases in territorial behaviours, conspecific aggression and previously observed mate turnover, which in turn might increase natal dispersal. Our study demonstrates how population density can affect the behaviour and space use of individuals, which is important for territory occupancy and fitness.
Fungal community demonstrates stronger dispersal limitation and less network connectivity than bacterial community in sediments along a large river

Published: August 2019

SummaryDespite the essential functions of sedimentary bacterial and fungal communities in biogeochemical cycling, little is known about their biogeographic patterns and driving processes in large rivers. Here we investigated the biogeographic assemblies and co‐occurrence patterns of sedimentary bacterial and fungal communities in the Jinsha River, one of the largest rivers in southwestern China. The mainstream of river was divided into upstream, midstream and downstream. The results showed that both bacterial and fungal communities differed significantly among three sections. For both communities, their composition variations in all sites or each river section were controlled by the combination of dispersal limitation and environmental selection, and dispersal limitation was the dominant factor. Compared with bacteria, fungi had stronger dispersal limitation. Co‐occurrence network analyses revealed higher network connectivity but a lower proportion of positive interaction in the bacterial than fungal network at all sites. In particular, the keystone species belonging to bacterial phyla Proteobacteria and Firmicutes and fungal phyla Ascomycota and Chytridiomycota may play critical roles in maintaining community function. Together, these observations indicate that fungi have a stronger dispersal limitation influence and less network connectivity than bacteria, implying different community assembly mechanisms and ecological functions between bacteria and fungi in large rivers.
Adoption of LGBT‐friendly practices: The effect of institutional pressures and strategic choice

Published: August 2019

AbstractThis study explores contextual and organisational factors that influence the likelihood of adopting lesbian, gay, bisexual, and transgender (LGBT)‐friendly practices. Drawing on institutional theory, we hypothesise that state laws, state conservativism, and localised LGBT‐friendliness density will have a direct effect on the adoption of LGBT‐friendly practices. Given the observed variation in the adoption of these practices, we also draw on strategic choice and the upper echelons perspective and hypothesise that the effect of institutional mechanisms is moderated by the beliefs and values of powerful organisational agents (chief executive officers and boards of directors). Our sample consists of 201 U.S.‐based Fortune 1000 companies over a period of seven years, and we test our hypotheses using a Cox proportional hazards survival analysis. Our results offer support for the role of state conservativism and localised LGBT‐friendliness density in the likelihood of LGBT‐friendly practices adoption, as well as for the moderating role of chief executive officer and board of directors' political orientation.
Public Perceptions of California's Exceptional Drought
Authors: Heeren Alexander , Pathak Tapan B. , Matlock Teenie , Conklin Martha 
Published: August 2019

AbstractWhile the exceptional drought in California ended in 2017, the state is expected to experience similar droughts in the future. Understanding how individuals perceive the causes and consequences of drought will help frame future communication and planning efforts. We surveyed a panel of Californian residents about their perceptions of the 2012–2017 drought. We found a major disconnect in how our respondents perceived drought and water use. Respondents perceived the drought as being caused primarily by climatic factors and underestimated the role human water use, particularly agricultural use, had in exacerbating drought. Comparing our respondents across the state and across socio‐demographics, there were few differences in concern about drought but several differences in how residents thought drought should be managed. Such research can help water managers communicate about the specific concerns the public has about future droughts, as well as address misperceptions about the relationship between drought and water use.
Progress in understanding hypersensitivity reactions to nonsteroidal anti‐inflammatory drugs

Published: August 2019

AbstractNonsteroidal anti‐inflammatory drugs (NSAIDs), the medications most commonly used for treating pain and inflammation, are the main triggers of drug hypersensitivity reactions. The latest classification of NSAIDs hypersensitivity by the European Academy of Allergy and Clinical Immunology (EAACI) differentiates between cross‐hypersensitivity reactions (CRs), associated with COX‐1 inhibition, and selective reactions, associated with immunological mechanisms. Three phenotypes fill into the first group: NSAIDs‐exacerbated respiratory disease, NSAIDs‐exacerbated cutaneous disease and NSAIDs‐induced urticaria/angioedema. Two phenotypes fill into the second one: single‐NSAID‐induced urticaria/angioedema/anaphylaxis and single‐NSAID‐induced delayed reactions. Diagnosis of NSAIDs hypersensitivity is hampered by different factors, including the lack of validated in vitro biomarkers and the uselessness of skin tests. The advances achieved over recent years recommend a re‐evaluation of the EAACI classification, as it does not consider other phenotypes such as blended reactions (coexistence of cutaneous and respiratory symptoms) or food‐dependent NSAID‐induced anaphylaxis. In addition, it does not regard the natural evolution of phenotypes and their potential interconversion, the development of tolerance over time or the role of atopy. Here, we address these topics. A state of the art on the underlying mechanisms and on the approaches for biomarkers discovery is also provided, including genetic studies and available information on transcriptomics and metabolomics.
