Authors: Zhang Jingxiao , Li Hui , Golizadeh Hamed , Zhao Chuandang , Lyu Sainan , Jin Ruoyu
Published: March 2020

Purpose

This research aims to develop an approach to assess the reliability of integrated construction supply chainsviaan integrated model of building information modelling (BIM) and the lean supply chain (LSC). It reflects the synergistic workflow between BIM and LSC as a novel approach to improve the reliability of construction projects.

Design/methodology/approach

This research evaluates the reliability of the BIM-LSC approach through a combination of entropy theory, set pair analysis (SPA), and Markov chains (EESM). An exploratory survey was conducted to collect data from 316 industry professionals experienced in BIM and LSC. Subsequently, multiple cycles of calculations were performed with indirect data inputs. Finally, a reliability evaluation index is established for the BIM-LSC approach and potential applications are identified.

Findings

The results show that the EESM model of BIM-LSC developed in this study can handle not only supply chain reliability evaluation at a given state but also the prediction of reliability in supply chain state transitions due to changing project conditions. This is particularly relevant to the current environment of the construction project, which is characterised by an increasing level of complexity in terms of labour, technology, and resource interactions.

Research limitations/implications

Future research could consider the accuracy and validity of the proposed model in real-life scenarios with by considering both quantitative and qualitative data across the entire lifecycle of projects.

Practical implications

The research offers a model to evaluate the reliability of the BIM-LSC approach. The accuracy of BIM supply chain reliability analysis and prediction in an uncertain environment is improved.

Originality/value

The BIM-LSC reliability evaluation and prediction presented in this study provides a theoretical foundation to enhance understanding of the BIM-LSC in the construction project context.
What drives job satisfaction in IT companies?
Authors: Moro Sérgio , Ramos Ricardo F. , Rita Paulo
Published: March 2020

Purpose

Strategic goal achievement in every sector of a company relies fundamentally on the firm's employees. This study aims to disclose the factors that spur employees of major Information Technology (IT) companies in the United States (US).

Design/methodology/approach

In this paper, 15,000 reviews from the top 15 United States IT companies were collected from the social media platform Glassdoor to uncover the factors that satisfy IT employees. To learn the most meaningful features that influence the scores, positive and negative remarks, as well as advice to the management team, were analyzed through a support vector machine.

Findings

Results highlight a positive attitude of coworkers, contributing to a positive environment and job satisfaction. However, unsatisfied IT employees reveal that work exhaustion is the main reason for their job dissatisfaction.

Practical implications

IT human resource departments can use these valuable insights to align their strategies in accordance with their employees' desires and expectations in order to thrive.

Originality/value

The study highlights the relevance of IT companies to understand the reasons behind their employees' satisfaction. Up until now, little is known concerning the variants of job satisfaction among IT employees, enriching the understanding in this particular professional area.
An integrative framework of supply chain flexibility
Authors: Liao Ying
Published: March 2020

Purpose

It is crucial to recognize that supply chain flexibility is important to build sustainable competitive edge in coping with uncertainty. This study puts forth an empirically supported integrative framework to understand supply chain flexibility from market-oriented and network-oriented perspectives, interrelationships among its dimensions and the effect of supply chain complexity as a contingent factor.

Design/methodology/approach

The online survey data were collected from 201 manufacturing companies and checked for common method variance, validity and reliability. Structural equation modeling was then used to test the hypotheses.

Findings

The results of this study demonstrate that there are interrelationships among market-oriented and network-oriented supply chain flexibility dimensions. It is the flexibility embedded in the supply chain network configuration that plays critical roles in superior performance in flexibility capabilities to create customer values. The interrelated effect among flexibility dimensions is contingent on the magnitude of the supply chain complexity corresponding to the number of supply chain tiers.

Originality/value

This study takes a step to advance understanding of supply chain flexibility from an integrative point of view consisting of market-oriented and network-oriented perspectives. This study is expected to provide practitioners the foundation to implement supply chain flexibility considering the interrelationships among flexibility dimensions. Our results suggest that to carry out a supply chain flexibility strategy, the vertical complexity of the supply chain structure needs to be taken into consideration.

Authors: G. Girish , V. Anandakrishnan
Published: March 2020

Purpose

This study aims to investigate and present the tribological behaviour of recursively friction stir processed 7075 aluminium alloy.

Design/methodology/approach

In this work, aluminium 7075 alloy is friction stir processed recursively by varying the tool rotational speed, traverse speed and the number of passes. Wear pins for testing were extracted from the processed zone and the surfaces were prepared. Wear tests were conducted as per the standard on a pin-on-disc wear testing machine at constant testing conditions and the corresponding tribological properties were analysed. The worn surface and the debris were analysed using a field-emission scanning electron microscope with energy dispersive spectroscopy analysis and elemental mapping to identify the mode of wear mechanism.

Findings

The experimental results indicate that the specimen fabricated at 1,150 rpm of tool rotation speed and 60 mm/min of traverse speed with 4 passes had the highest wear resistance and the minimum friction coefficient.

Originality/value

This paper details the effect of recursive friction stir processing on the surface of AA 7075 to improve the tribological properties.

The moderating role of environmental munificence on innovativeness in B2B markets
Authors: Gul Misra Cagla
Published: March 2020

Purpose

The purpose of this paper is to understand the relationship between two business orientations, namely, entrepreneurial orientation and market orientation, and innovativeness taking into account the moderating influence of environmental munificence.

Design/methodology/approach

This is a multiple respondent quantitative study. A total of 312 marketing managers middle level and above from 79 firms participated in the survey. Multiple regression and hierarchical multiple regression was the method of choice for data analysis.

Findings

Findings indicate that environmental munificence moderates the entrepreneurial orientation – innovativeness relationship. Findings reveal that even though a significant impact of entrepreneurial orientation is not present on innovativeness, this insignificance may be due to environmental munificence. Market orientation has a direct positive impact on innovativeness, and environmental munificence negatively moderates this relationship suggesting that when the environment is less munificent, the market orientation – innovation link becomes stronger.

Practical implications

Managers should be aware that the more munificent an environment becomes, having an entrepreneurial orientation will be more important for innovativeness. In addition, results of this study suggest that being market oriented more strongly impacts a firm’s ability to innovate in non-munificent environments where growth opportunities are undesirable.

Originality/value

This study is unique in that it is a multi-respondent study with respondents from different layers of each participating organization, incorporating the moderating impact of the business environment’s munificence on business orientations–innovativeness relationship.
Enhancing customer-linking marketing capabilities using marketing analytics
Authors: Cao Guangming , Tian Na
Published: March 2020

Purpose

Evidence in the literature has indicated that customer-linking marketing capabilities such as customer relationship management (CRM) and brand management are important drivers of marketing performance and that marketing analytics use (MAU) enables firms to gain valuable knowledge and insights for improving firm performance. However, there has been little focus on how firms improve their CRM and brand management via MAU. This study aims to draw on the absorptive capacity theory, research on marketing capabilities and marketing analytics to examine the capability-developing mechanisms that enable a firm to use marketing analytics to enhance its CRM and brand management capabilities, thereby improving its marketing performance.

Design/methodology/approach

A research model is developed and tested based on an analysis of 289 responses collected using an online survey from middle and senior managers of Chinese firms with sufficient knowledge and experience in using marketing analytics for survey participation.

Findings

The findings demonstrate that MAU is positively related to both CRM and brand management capabilities, which in turn are positively associated with marketing performance; and that both CRM and brand management capabilities mediate the relationship between MAU and marketing performance.

Research limitations/implications

The study’s outcomes were based on data collected from a survey, which was distributed using mass e-mails. Thus, the study is unable to provide a meaningful response rate. The research results are based on and limited to Chinese firms.

Practical implications

MAU is essential for enhancing customer-linking marketing capabilities such as CRM and brand management, but it alone is not sufficient to improve marketing performance. Firms wishing to improve marketing performance should leverage the knowledge and insights gained from MAU to enhance their critical customer-linking marketing capabilities.

Originality/value

This study explicates the capability-developing mechanisms through which a firm can use its market-sensing capability as manifested by MAU to enhance customer-linking marketing capabilities and to improve its marketing performance. In so doing, this study extends our understanding of the critical role of absorptive capacity in helping firms identify, assimilate, transform and apply valuable external knowledge.
Key challenges in strategic start-up communication
Authors: Wiesenberg Markus , Godulla Alexander , Tengler Katharina , Noelle Inga-Marit , Kloss Julia , Klein Natalie , Eeckhout David
Published: March 2020

Purpose

The paper represents a starting point of a broader research project in strategic start-up communication. The main purpose of this study is to demonstrate the current state of research in this area and to compare those insights with an explorative study on the start-up ecosystem.

Design/methodology/approach

A neo-institutional framework is combined with the dual narrative framework of strategic communication and emergence to explain the emergence of strategic communication in this organizational field (start-up ecosystems). Research questions are derived from a systematic literature review and subjected to exploratory testing in two different qualitative surveys, with experts and investors, reflecting an external perspective, and with start-ups themselves.

Findings

Results from the literature review and the explorative interviews with expert external actors indicate eight areas in which start-ups face strategic communication challenges: the basic orientation of strategic communication, branding, external image, stakeholder relations, allocation of financial resources, owner centricity, human resources and internal communication. External consultants and funders recommend highly planned approaches like target group-oriented communication, well thought-out positioning with uniform messages and precisely applied communication channels. However, the internal perspective of start-ups presents a contrary picture based on emergent products of strategic communication.

Research limitations/implications

The study indicates the importance of both the emergence in strategic start-up communication and the demonstration of planned strategic communication. Investigating a whole start-up ecosystem in a country regarding the emergence of strategic communication forms, practices and products offers potential for cross-country comparative research.

Practical implications

The findings indicate key challenges of strategic communication of start-ups. Bearing in mind these key challenges when founding a start-up can make a difference in the success of the start-up.

Originality/value

The article presents the first systematic literature review in the area of strategic start-up communication and a theoretical framework for further investigation. Moreover, the results of the explorative study demonstrate the importance of the different forms of planning and emergence in strategic start-up communication. Hence, this paper provides practical implications for practitioners working and investing in the start-up ecosystem.
The spatial justice in the distribution of built outdoor sports facilities
Authors: Asefi Ahmadali , Ghanbarpour Nosrati Amir
Published: March 2020

Purpose

Sports facilities can play a vital role in encouraging physical activity and sport. Also, just the distribution of sports facilities is very important for better access to these facilities. Therefore, the purpose of this study is to evaluate spatial justice in the distribution of built outdoor sports facilities in the city of Isfahan, Iran and provide insight for planning in terms of equitable accessibility.

Design/methodology/approach

All facilities located in the 15 areas of the city, whether private or public, built for the purpose of physical activity and sports programs were considered in this study (107 cases). To obtain information on the locations of the outdoor sports facilities, Isfahan Atlas data, which has been compiled by Isfahan Municipality was used. Arc geographic information systems environment and its different algorithms were also used to perform different calculations and prepare maps.

Findings

The results indicated the unfair distribution of built outdoor sports facilities in the city of Isfahan in terms of spatial justice based on the number of built outdoor sports facilities in each area, the population, land area, population density and the spatial pattern of the facilities.

Practical implications

In this regard, urban authorities and sport managers should make an effort to decrease or obviate inequity in access to outdoor sports facilities for the purpose of promoting participation in physical activity and sport and providing residents with numerous other benefits.

Originality/value

This paper has concluded that spatial justice in the distribution of built outdoor sports facilities for the improvement of access to these facilities is very important.
Implementing innovative customer due diligence: proposal for universal model
Authors: Shust Pavel M. , Dostov Victor
Published: March 2020

Purpose

The purpose of this paper is to present the identification-verification-confirmation of identity (IVCid) model that can be used to retroactively analyze the existing customer identification programs and devise new ones that can be used in face-to-face or non-face-to-face environment.

Design/methodology/approach

This paper outlines the main elements of the customer due diligence (CDD) process and identifies those which may present a barrier to the customers. It then outlines the IVCid model. The model is used to analyze existing CDD approaches in physical presence, using reliable databases, biometrics and electronic signatures.

Findings

The IVCid model suggests that any customer identification program contains three elements: identification (collection of information), verification (checking the veracity of information) and confirmation of identity (linking the information to the individual). The accuracy of this model is confirmed by the analysis of the existing CDD procedures in some countries.

Research limitations/implications

This paper looks at a limited number of practical cases of CDD implementation. Further research might be needed to assess the strengths and weaknesses of biometric-based or e-signature-based solutions. Research might be needed to establish links between the IVCid model and financial inclusion.

Practical implications

The IVCid model allows for “modular” approach for the CDD procedures. It also underlines some risks associated with current CDD models.

Social implications

The IVCid model can be used to devise the CDD procedures that more effectively contribute to financial inclusion.

Originality/value

This paper proposes the first universal model for the CDD procedures that works for both face-to-face and remote scenarios while also being technology- and business-neutral.
The impact of augmented reality on overall service satisfaction in elaborate servicescapes
Authors: Gäthke Jana
Published: March 2020

Purpose

Artificial intelligence (AI) has the potential to facilitate service provision and forms the basis for various smart services, such as augmented reality (AR) apps. The purpose of this study is to investigate the guiding help of an AR app in elaborate servicescapes, which typically constitute complex environments. The study examines how an AR guidance app impacts service evaluation.

Design/methodology/approach

This research conducted a field experiment during a trade fair. It employed a two-group between-subjects design (AR app vs traditional 2D map) in order to examine how guidance through complex environments affects overall service satisfaction. Hypotheses were tested through analysis of covariance (ANCOVA), moderated regression, and PROCESS.

Findings

The results reveal that an AR app compared to a traditional 2D map leads to significantly higher overall service satisfaction. This relationship is mediated by perceived complexity reduction. Moreover, perceived behavioral control acts as a moderator. Further, the usage of an AR app tends to improve customer loyalty.

Practical implications

Managers learn whether it is worthwhile to employ AR apps in elaborate service environments as well as how to implement them.

Originality/value

By conducting a field experiment and examining a concrete AI-based smart service (i.e. an AR app), this research adds to the AI literature, which has been mostly conceptual, and contributes to the underexamined field of elaborate servicescapes.
Effect of network embeddedness on innovation performance of small and medium-sized enterprises
Authors: Dogbe Courage Simon Kofi , Tian Hongyun , Pomegbe Wisdom Wise Kwabla , Sarsah Sampson Ato , Otoo Charles Oduro Acheampong
Published: March 2020

Purpose

The purpose of this study was to identify if network embeddedness and innovation performance relationship, which has been largely studied in multinational enterprises (MNEs) and large corporations, was also applicable in the context of small and medium-sized enterprises (SMEs). Secondly, the authors also sought to identify the moderating role of innovation openness in the relationship between network embeddedness and SMEs' innovation performance.

Design/methodology/approach

Empirical analysis was based on 388 SMEs in Ghana. Various validity and reliability checks were conducted before the presentation of the actual analysis, which was conducted using the structural equation modeling in Amos (v.23).

Findings

Findings revealed that, in the context of SMEs, network embeddedness had significant positive effect on innovation performance. The authors further identified that SMEs with both high levels of network embeddedness and innovation openness had a much higher performance in their innovation, compared to SMEs that relied solely on network embeddedness.

Research limitations/implications

The current study found innovation openness to further strengthen the relationship between network embeddedness and SMEs' innovation performance. The relationship between network embedded and SME's innovation could, however, be mediated by knowledge transfer mechanisms, so future studies should pay particular attention to the mediating mechanisms.

Practical implications

Management of SMEs is advised to develop conducive organizational structures, such as trust, openness to collaboration and so on, for effective innovative knowledge transfer and transformation.

Originality/value

Past research studies on network embeddedness and innovation performance have dominantly resided in MNE and large corporations. This current study extends the body of knowledge by extending the network embeddedness and innovation performance research studies to SME context.

Tuna trade‐offs: Balancing profit and social benefits in one of the world’s largest fisheries
Authors: Willis Ciara , Bailey Megan
Published: March 2020

The western and central Pacific Ocean (WCPO) tuna fishery is one of the world's largest in terms of both catch volume and value, providing over half of global tuna catch with a landed value of US $5.84 billion in 2017. Fishing is conducted by both large‐ and small‐scale fleets, with fisheries subsidies disproportionately benefiting the former. The primary objective of this study was to determine the optimal distribution of effort between two large‐scale fisheries (LSF) and two small‐scale fisheries (SSF) in the WCPO under three scenarios: to maximize industry benefits, minimize subsidization or maximize food supply. The objective was approached using a bioeconomic game‐theoretic model. Results indicate opposite distributions of effort to maximize industry benefits (all fishing conducted by LSF) or to minimize subsidization (all fishing by SSF), with more balanced effort distributions to maximize food supply. Total value of capacity‐enhancing subsidies in optimal scenarios ranged from $1.4 billion when industry benefits were maximized to $0.2 billion when subsidization was minimized. Investigation of suboptimal scenarios reveals the flexibility of these results, with wide ranges in outputted state variables for a given goal. Difficulty was encountered in modelling the SSF sector due to data deficiencies, a well‐recognized issue in managing SSF. Investments towards “data equity” to help ensure that management decision‐making can properly account for the SSF sector would be useful. This study has implications for the objectives we set in fisheries management, and the potential trade‐offs, often value‐driven in nature, that we must make explicit in that management.
Vulnerability of marine resources to small‐scale fishing in a tropical area: The example of Sunda Strait in Indonesia

Published: March 2020

Although small‐scale fisheries (SSF) play an important socio‐economic role in developing nations, overfishing seems to be increasing the risk of stock vulnerability. This study aims to quantify the pressure of SSF on fish stocks in Sunda Strait (Indonesia) using several biological indicators that are important in quantifying fishing pressure. Data on these indicators were collected monthly for three years (2012–2014) in one of the main fishing ports of the area. The results provide evidence that, although SSF would appear to be the most environmentally sustainable of all the fishing techniques being used today in the coastal waters of Indonesia, the impact of SSF fishing on juvenile fishes in certain areas such as the Sunda Strait must not be underestimated. The results also show the need to protect immature fish of species that are not only commercialised but are also important in subsistence fisheries. Although further studies are needed to assess the impact of SSF on fish stocks in the area, it is suggested management recommendations that include the implementation of marine‐protected areas in nursery grounds and establishing minimum landing sizes well above the size‐at‐maturity for each species, are needed.
Behavioral Therapy Preferences in People With Migraine
Authors: Minen Mia T. , Jalloh Adama , Begasse de Dhaem Olivia , Seng Elizabeth K.
Published: March 2020

Background

There are safe and well‐tolerated level A evidence‐based behavioral therapies for the prevention of migraine. They are biofeedback, cognitive behavioral therapy, and relaxation. However, the behavioral therapies for the prevention of migraine are underutilized.

Objectives

We sought to examine whether people with migraine with 4 or more headache days a month had preferences regarding the type of delivery of the behavioral therapy (in‐person, smartphone based, telephone) and whether they would be willing to pay for in‐person behavioral therapy. We also sought to determine the predictors of likelihood to pursue the behavioral therapy.

Methods

Using a cross‐sectional study design, we developed an online survey using TurkPrime, an online survey platform, to assess how likely TurkPrime participants who screened positive for migraine using the American Migraine Prevalence and Prevention screen were to pursue different delivery methods of the behavioral therapy. We report descriptive statistics and quantitative analyses.

Results

There were 401 participants. Median age was 34 [IQR: 29, 41] years. More than two thirds of participants (70.3%, 282/401) were women. Median number of headache days/ month was 5 [IQR: 2.83, 8.5]. Some (12.5%, 50/401) used evidence‐based behavioral therapy for migraine. The participants reported that they were “somewhat likely” to pursue in‐person or smartphone behavioral therapy and behavioral therapy covered by insurance but were neutral about pursuing the telephone‐based behavioral therapy. Participants were “not very likely” to pay out of pocket for the behavioral therapy. Migraine‐related disability as measured by the MIDAS grading score was associated with likelihood to pursue the behavioral therapy in‐person (P = .004), via telephone (P = .015), and via smart phone (P < .001), and covered by insurance (P = .001). However, migraine‐related disability was not associated with likelihood to pursue out of pocket (P = .769) behavioral therapy. Pain intensity was predictive of likelihood of pursuing the behavioral therapy for migraine when covered by insurance. Other factors including education, employment, and headache days were not predictors.

Conclusion

People with migraine prefer in‐person and smartphone‐based behavioral therapy to telephone‐based behavioral therapy. Migraine‐related disability is associated with likelihood to pursue the behavioral therapy (independent of type of delivery of the behavioral therapy‐in‐person, telephone based or smartphone based). However, participants were not very likely to pay for the behavioral therapy.
REDISTRIBUTION AND FISCAL UNCERTAINTY SHOCKS
Authors: Saijo Hikaru
Published: March 2020

This article studies the impact of fiscal uncertainty shocks. In micro data, noncapital holders reduce consumption persistently in response to an increase in fiscal uncertainty whereas capital holders do not. Motivated by this evidence, I introduce limited capital market participation and show that it magnifies the fall in economic activity due to a fiscal uncertainty shock and induces macroeconomic comovement. This is because the limited participation model captures individual uncertainty about redistribution. When agents are ambiguity averse, this uncertainty about redistribution has first‐order effects. As a result, the model successfully matches the empirical responses of macro and household variables.
Efficacy of intraoperative wireless ultrasonography for uterine incision among patients with adherence findings in placenta previa
Authors: Choi Min J. , Lim Chan M. , Jeong Dahoe , Jeon Hae‐Rin , Cho Kyung J. , Kim Suk Y.
Published: March 2020

Aim

We evaluated the effectiveness of intraoperative wireless ultrasonography in determining the location of uterine incision during cesarean delivery in patients with placenta previa who have sonographic adherence findings in order to assess intraoperative blood loss and maternal morbidity.

Methods

A prospective study using wireless sonography, including 15 patients with previa, was conducted among women with singleton pregnancies who delivered by cesarean section between August 1, 2017, and August 30, 2019. Retrospective study for the control group included 32 patients with placenta previa who underwent cesarean section between January 1, 2016, and July 31, 2017, without wireless sonography. Patients with previa who had adherence findings in prenatal sonography were included in both groups. Logistic regression was used to identify the association between massive intraoperative bleeding loss and use of wireless ultrasound sonography.

Results

Intraoperative blood loss was significantly reduced in the study group compared to that in the control group (P = 0.009). The hospital stay was significantly shorter in the study group compared to the control group (5 days vs 6 days, P < 0.001). The use of intraoperative wireless sonography (P = 0.01) had a significant association with massive intraoperative hemorrhage in multivariable analysis.

Conclusion

Our study is the first study to apply a wireless ultrasound sonography device in women with placenta previa during cesarean section to examine maternal morbidity. This latest wireless ultrasound sonography device is advantageous for uterine incision guidance in women with placenta previa and improves maternal morbidity by reducing intraoperative hemorrhage.
Temporal and spatial dynamics of surface run‐off from Lake Basaka catchment (Ethiopia) using SCS‐CN model coupled with remote sensing and GIS
Authors: Dinka Megersa O. , Klik Andreas
Published: March 2020

The Lake Basaka catchment (Ethiopia) has undergone a significant land use–land cover (LULC) change and lake level rise over the past five decades. Significant quantities of water and sediment flow annually into the lake through erosion processes. An appropriate method of estimating the surface run‐off from such ungauged and dynamic catchment is extremely important for delineating sensitive areas (based on run‐off responses) to be protected and for development of suitable measures to reduce run‐off and associated soil loss. Reliable prediction of run‐off, however, is very difficult and time‐consuming for catchments such as that of Lake Basaka. The present study estimated the dynamics of surface (direct) run‐off using the NRCS‐CN model in ArcGIS, assisted by remote sensing and ancillary data. The results indicated the Lake Basaka catchment experienced significant temporal and spatial variability in its run‐off responses, depending on the rainfall (amount and distribution) pattern and LULC changes. A significant run‐off increase occurred after 1973, consistent with significant LULC changes and lake level increments occurring after that period. A reduced vegetation cover also resulted in increased run‐off coefficient of the lake catchment from 0.11 in the 1970s to 0.23 in the 2000s, indicating the important need to consider possible future LULC evolution when forecasting the lake catchment run‐off behaviour.
The prevalence of urinary incontinence in men and women aged 40 years or over in China, Taiwan and South Korea: A cross‐sectional, prevalence‐based study
Authors: Sumarsono Budiwan , Jong Jar Jar , Wang Jian‐Ye , Liao Limin , Lee Kyu‐Sung , Yoo Tag Keun , Liu Shih‐Ping , Chuang Yao‐Chi
Published: March 2020

Objectives

To assess prevalence of urinary incontinence (UI), including urgency UI (UUI), stress UI (SUI) and mixed UI (MUI) in individuals aged ≥40 years in China, Taiwan and South Korea.

Method

This was a post hoc analysis of a cross‐sectional, questionnaire‐based internet survey. Participants were asked questions relating to urinary symptoms, health‐related quality of life (HRQoL) and mental health (using the HRQoL 12‐item short form health survey mental health and physical domains, and the Hospital Anxiety and Depression Scale), visits to healthcare professionals (HCPs) for any reason or for urinary symptoms, treatments for urinary symptoms and treatment satisfaction.

Results

Of 8284 survey participants, 1818 (22%) reported any UI (men 17.3%, women 26.4%). MUI was the most prevalent (overall 9.7%, men 6.8%, women 12.6%) followed by SUI (overall 7.9%, men 5.1%, women 10.7%) and UUI (overall 4.3%, men 5.5%, women 3.2%). HRQoL, anxiety and depression scores were poor in all participants with UI; MUI was associated with the worst scores. Of the participants with UI, 46.9% visited HCPs for urinary symptoms (highest proportion [62.7%] among participants with MUI). Approximately 80% of participants with UI followed treatment, with prescribed medicine being the most common form (38.1%). Over half of participants (59.6%) were somewhat, very, or extremely satisfied with their treatment. MUI was associated with least satisfaction.

Conclusion

UI was associated with substantial problems, including an adverse impact on HRQoL. Medication failed to satisfy many individuals with UI. Efforts to educate the public and physicians about the impact of UI could improve diagnosis and treatment rates.
No‐arbitrage implies power‐law market impact and rough volatility
Authors: Jusselin Paul , Rosenbaum Mathieu
Published: March 2020

Market impact is the link between the volume of a (large) order and the price move during and after the execution of this order. We show that in a quite general framework, under no‐arbitrage assumption, the market impact function can only be of power‐law type. Furthermore, we prove this implies that the macroscopic price is diffusive with rough volatility, with a one‐to‐one correspondence between the exponent of the impact function and the Hurst parameter of the volatility. Hence, we simply explain the universal rough behavior of the volatility as a consequence of the no‐arbitrage property. From a mathematical viewpoint, our study relies, in particular, on new results about hyper‐rough stochastic Volterra equations.
Critical Moments Reconsidered: When We Say Yes and When We Say No
Authors: Menkel‐Meadow Carrie
Published: March 2020

This article adds consideration of context to the continuing focus on critical moments. In particular, there are contextual circumstances and other factors in which a critical moment involves bringing things to a halt—saying “no.” This is contrary to the improvisational notion of “yes, and” and it is underappreciated in the negotiation literature.

In order to combine high‐quality research with minimal harm to animals, a prospective severity assessment for animal experiments is legally required in many countries. In addition, an assessment of the evidence‐based severity level might allow realistic harm–benefit analysis and the appraisal of refinement methods. However, only a few examples describe the distress of animals by simple, cost‐efficient, and noninvasive methods. We, therefore, evaluated the severity of an orthotopic mouse model for pancreatic cancer using C57BL/6J mice when pursuing two different chemotherapies. We assessed fecal corticosterone metabolites, body weight, distress score, and burrowing, as well as nesting activity. Moreover, we established a multifactorial model using multivariate logistic regression to describe animal distress. This multifactorial analysis revealed that metformin + galloflavin treatment caused higher distress than metformin + α‐cyano‐4‐hydroxycinnamate therapy. Similar results were obtained by using the best cutoff calculated by Youden's J index when using only single parameters, such as burrowing activity or fecal corticosterone metabolite concentration. Thus, the present study revealed that single readout parameters, as well as multivariate analysis, can help to assess the severity of animal experiments and detect side effects of therapies.

Published: March 2020

Purpose

To investigate the prevalence and risk factors of Uncorrected Refractive Errors (URE) for distance in elderly residents in ‘homes for the aged’ in Hyderabad, India.

Methods

Individuals aged ≥60 years and residing in ‘homes for the aged’ in Hyderabad, India for a minimum of 1 month and providing consent for participation were recruited. All participants underwent visual acuity assessment, refraction, slit lamp biomicroscopy, intraocular pressure measurement, fundus examination, and retinal imaging. Monocular presenting visual acuity was recorded using a logMAR chart. Objective and subjective refraction were performed, and best‐corrected visual acuity was recorded. URE was defined as presenting visual acuity worse than 6/12 but improving to 6/12 or better with refraction. Univariable and multivariable logistic regression analyses were used to assess the risk factors associated with URE.

Results

In total, 1 513 elderly participants were enumerated from 41 homes of which 1 182 participants (78.1%) were examined. The mean age of participants was 75.0 years (standard deviation 8.8 years; range: 60–108 years). 35.4% of those examined were men and 20.3% had no formal education. The prevalence of URE was 13.5% (95% CI: 11.5–15.5;n = 159). On applying multiple logistic regression analysis, compared to those living in private homes, the odds of URE were significantly higher among the elderly living in the aided homes (OR: 1.65; 95% CI: 1.11–2.43) and free homes (OR: 1.67; 95% CI: 1.00–2.80). As compared to those who reported having an eye examination in the last 3 years, the odds of URE were higher among those who never had an eye examination in the last three years (OR: 1.51; 95% CI: 1.07–2.14). Similarly, those who had unilateral cataract surgery (OR: 1.80; 95% CI: 1.10–2.93) or bilateral cataract surgery (1.69; 95% CI: 1.10–2.56) had higher odds of URE compared to those elderly who were not operated for cataract. Gender, self‐report of diabetes, and education were not associated with URE.

Conclusions

A large burden of URE was found among the residents in the ‘homes for the aged’ in Hyderabad, India which could be addressed with a pair of glasses. Over 40% of the residents never had an eye examination in the last three years, which indicates poor utilisation of eye care services by the elderly. Regular eye examinations and provision of spectacles are needed to address needless URE for distance among the elderly in residential care in India.

Background

Antidepressant use later in pregnancy has been associated with preeclampsia and postpartum haemorrhage (PPH) in some studies.

Objectives

To evaluate the association between patterns of prenatal antidepressant dose across gestationand risk of precclampsia and PPH.

Methods

We utilised OptumLabs® Data Warehouse (2012‐2016) administrative health care claims, identifying 226 932 singleton liveborn deliveries for this retrospective cohort study. Antidepressant dispensing doses were converted to fluoxetine equivalents. Using k‐means longitudinal, we identified women with similar patterns of antidepressant exposure, that is, trajectory groups, during the first 20 and 35 gestational weeks. We estimated risk ratios (RR) and 95% confidence intervals (CI) for the association between trajectory groups and preeclampisa (20‐week groups) and PPH (35‐week groups), adjusting for demographics, co‐morbidities, and other psychotropic medications. Linear trend tests assessing increasing risk of the outcomes across groups were performed.

Results

Among 15 041 (6.6%) pregnancies exposed to an antidepressant, the following trajectory groups were identified: A‐low exposure, starting pregnancy at ~10 mg/d, with 1st trimester reduction/discontinuation, B‐low sustained exposure of ~20 mg/d, C‐moderate exposure (~40 mg/d) with 1st trimester reduction/discontinuation, D‐moderate sustained exposure of ~40 mg/d, and E‐high sustained exposure of ~75 mg/d. In the low exposure with reduction/discontinuation trajectory, risks were 8.2% for preeclampsia and 2.7% for PPH. Compared with this group, low, moderate, and high sustained trajectories were associated with preeclampsia (adjusted RR 1.17, 95% CI 1.01, 1.34; RR 1.31, 95% CI 1.12, 1.54; and RR 1.41, 95% CI 1.05, 1.90, respectively) and PPH (RR 1.32, 95% CI 1.05, 1.66; RR 1.35, 95% CI 1.03, 1.78; RR 2.51, 95% CI 1.69, 3.71, respectively); P < .01 for linear trend tests for both outcomes. There was no increased risk for either outcome for moderate exposure with reduction/discontinuation (trajectory C).

Conclusions

Women with sustained antidepressant exposure, especially at higher doses, were at increased risk for preeclampsia and PPH, but underlying depression and anxiety may contribute to the increased risk.
Advanced maternal age and risk of adverse perinatal outcome among women with congenital heart disease: A nationwide register‐based cohort study

Published: March 2020

Background

Women with maternal congenital heart disease have a higher risk of preterm birth (PTB) and giving birth to a small for gestational age (SGA) infant. Advanced maternal age (≥35 years) likewise increases the risk of PTB and SGA, probably explained by poorer cardiovascular status. It is likely that advanced maternal age is particularly detrimental in women with congenital heart disease.

Objectives

We aimed to determine whether the pattern of higher risk of PTB and SGA with higher maternal age varied among women with and without congenital heart disease. We hypothesised that the effect of age is higher among women with congenital heart disease.

Methods

We did a cohort study using Danish nationwide registers. Births from 1997 to 2014 were included. Cox regressions were used to estimate hazard ratios (HRs) for PTB and SGA. Universal and congenital heart disease‐specific references were used for comparison.

Results

We included 932 772 births among 548 314 women. HRs of PTB and SGA were 1.55 (95% confidence interval [CI] 1.37, 1.77) and 1.43 (95% CI 1.29, 1.58) in women with congenital heart disease as compared to women without. For both PTB and SGA, HRs were higher for women ≥35 years as compared to women aged 25‐29 years. HRs of PTB and SGA were higher among women with congenital heart disease within all strata of maternal age as compared to women without (eg 3.71, 95% CI 1.80, 7.63 vs 1.63, 95% CI 1.56, 1.70) for SGA for women aged 40‐44 years). The pattern of higher risk of PTB and SGA with higher maternal age was, however, similar among women with and without congenital heart disease.

Conclusions

Women with congenital heart disease had a higher risk of PTB and giving birth to an SGA infant at all maternal ages. These two risk factors did not, however, seem to potentiate each other.

Background and objective

People living with pulmonary fibrosis (PF) report unmet needs for information and support. Lung Foundation Australia (LFA) have developed the Peer Connect Service to facilitate telephone support for people with PF across Australia. This project documented the experiences of participants and the resources required to support the service.

Methods

Consenting participants took part in semi‐structured interviews by telephone. Primary peers (peers who agreed to initiate contact) and secondary peers (eligible patients who sought a peer match) were interviewed. Thematic analysis was undertaken by two independent researchers. Data were collected on the number of matches and contacts required to establish each match.

Results

Interviews were conducted with 32 participants (16 primary peers, 15 secondary peers and 1 who was both), aged from 53 to 89 years with 56% being male. Major themes included the value of shared experiences, providing mutual support and the importance of shared personal characteristics (e.g. gender and hobbies) in allowing information and emotional support needs to be met. Participants saw face‐to‐face contact with peers as highly desirable whilst acknowledging the practical difficulties. Primary peers were cognizant that their role was not to provide medical advice but to listen and share experiences. In the 12‐month period, 60 peer matches were made, each match requiring a minimum of seven staff contacts.

Conclusion

The Peer Connect Service provides a unique opportunity for people with PF to share experiences and offer mutual support. This telephone matching model may be useful in providing peer support for individuals with rare diseases who are geographically dispersed.
