Information technology, knowledge management and environmental dynamism as drivers of innovation ambidexterity: a study in SMEs
Authors: Soto-Acosta Pedro , Popa Simona , Martinez-Conesa Isabel 
Published: February 2018

PurposeThe purpose of this study is to assess the effect of technological, organizational and environmental factors on innovation ambidexterity and its influence on the performance of manufacturing small- and medium-sized enterprises (SMEs) as well as the moderating effect environmental dynamism on this relationship.Design/methodology/approachDrawing on the Technology–Organization–Environment theory and the Knowledge-Based View, this paper develops an integrative research model, which analyzes the network of relations using covariance-based structural equation modeling on a data set of 429 Spanish SMEs.FindingsThe results show that information technology capability, knowledge management capability and environmental dynamism are positively associated with innovation ambidexterity. In addition, environmental dynamism is found to strengthen the positive effect of innovation ambidexterity on firm performance.Practical implicationsThe study findings support the idea that innovation can be developed in an ambidextrous manner within a single SME as long as the firm is capable of creating a suitable organizational context and giving a prompt response to changes in the business environment.Originality/valueAlthough many studies have highlighted that being ambidextrous is more challenging for SMEs than for their larger counterparts, the vast majority of studies has been conducted in large companies. This paper extends prior literature by analyzing antecedents and outcomes of innovation ambidexterity in manufacturing SMEs.
Perfectionist decision-making style and ethical investment willingness
Authors: Lin Yu-Cheng , Huang Chiung-Yao , Wei Yu-Shan 
Published: February 2018

Purpose
The purpose of this paper is to examine the ethical investment willingness decision-making process to understand how investors evaluate corporate social responsibility (CSR) actions.

Design/methodology/approach
Data were collected through a survey of 298 individual investors and analyzed using structural equation modeling.

Findings
Results reveal that perfectionist decision-making style is positively related to perceived moral intensity, substitutability of financial returns, and ethical investment willingness. In addition, perceived moral intensity and substitutability of financial returns are positively related to ethical investment willingness. Finally, perceived moral intensity is positively related to substitutability of financial returns, and a two-factor causal mediation model is supported.

Research limitations/implications
The limitation of this study was that the pre-tests and sampling methods required all participants to have investing experience; however, procurement of trading information for each investor was impossible; thus, actual investment behaviors were undetermined. This study shed light on the mediating roles of perceived moral intensity and the substitutability of financial returns. Future studies can further investigate the factors influencing perceived moral intensity and the substitutability of financial returns.

Practical implications
Future ethical investment education can focus on cultivate the ability to distinguish ethical investments and change ethical investment willingness into actual investment behavior.

Originality/value
Understanding the relationship between these variables can help understand why ethical investment willingness varies among investors and how the traditional financial theory investment decision model should be revised as, internationally, more people have begun to observe CSR and sustainable development.
Joint facies and rock properties Bayesian amplitude‐versus‐offset inversion using Markov random fields
Authors: Gunning James , Sams Mark 
Published: February 2018

ABSTRACTSeismic reflection pre‐stack angle gathers can be simultaneously inverted within a joint facies and elastic inversion framework using a hierarchical Bayesian model of elastic properties and categorical classes of rock and fluid properties. The Bayesian prior implicitly supplies low frequency information via a set of multivariate compaction trends for each rock and fluid type, combined with a Markov random field model of lithotypes, which carries abundance and continuity preferences. For the likelihood, we use a simultaneous, multi‐angle, convolutional model, which quantifies the data misfit probability using wavelets and noise levels inferred from well ties. Under Gaussian likelihood and facies‐conditional prior models, the posterior has simple analytic form, and the maximum a‐posteriori inversion problem boils down to a joint categorical/continuous non‐convex optimisation problem. To solve this, a set of alternative, increasingly comprehensive optimisation strategies is described: (i) an expectation–maximisation algorithm using belief propagation, (ii) a globalisation of method (i) using homotopy, and (iii) a discrete space approach using simulated annealing. We find that good‐quality inversion results depend on both sensible, elastically separable facies definitions, modest resolution ambitions, reasonably firm abundance and continuity parameters in the Markov random field, and suitable choice of algorithm. We suggest usually two to three, perhaps four, unknown facies per sample, and usage of the more expensive methods (homotopy or annealing) when the rock types are not strongly distinguished in acoustic impedance. Demonstrations of the technique on pre‐stack depth‐migrated field data from the Exmouth basin show promising agreements with lithological well data, including prediction accuracy improvements of 24% in and twofold in density, in comparison to a standard simultaneous inversion. Much clearer and extensive recovery of the thin Pyxis gas field was evident using stronger coupling in the Markov random field model and use of the homotopy or annealing algorithms.
Application of amplitude spectrum and genetic inversion to determine shaly facies distribution: a case study: Murzuq Basin, Libya
Authors: Abushalah Yousf , Serpa Laura 
Published: February 2018

ABSTRACTLate Ordovician glacial deposits of the Mamuniyat Formation are the main oil reservoir in the Murzuq Basin in Libya. Autopicking the strong reflection at the base of the Silurian shales can be used to map the top of the Mamuniyat reservoir in the area where it is in direct contact with the Silurian shales. However, in areas where the Bir Tlacsin Formation, a mud‐prone unit, is between the Silurian shales and the Mamuniyat reservoir, the top of the Mamuniyat is difficult to pick because the units juxtaposed across the boundary are too similar to produce a strong reflection. Defining the Bir Tlacsin facies is important because it impacts hydrocarbon accumulation and migration. To predict the distribution of the shaly facies of Bir Tlacsin and enhance mapping of the top Mamuniyat reservoir, we utilized a continuous wavelet transform to identify the distinctive thickness of the Hot Shale and Bir Tlacsin units. We also used genetic inversion to distinguish the bulk density of the Bir Tlacsin facies. A 64 Hz frequency gave good time resolution to the amplitude spectrum and was used to predict the facies distribution of the Bir Tlacsin. In contrast, the 24 Hz frequency showed good frequency resolution of the amplitude spectrum and was used to estimate the temporal thickness of the non‐reservoir unit of Bir Tlacsin and Hot Shale. That estimate was then used to modify the autopick horizon for the base of the Silurian reflector to approximate the top of the Mamuniyat reservoir. Because of the large density contrast between the shaly facies of the Bir Tlacsin and the underlying and overlying units, inverted density also provides a way to predict the distribution of the Bir Tlacsin through estimated temporal thickness and to enhance mapping of the top Mamuniyat reservoir through mapping the base of the inverted density of the Bir Tlacsin. A comparison between mapping of the top reservoir using spectral decomposition and inverted density with respect to autopick shows that both methods improved the top of the Mamuniyat reservoir mapping. Prediction of the presence of Bir Tlacsin and improved accuracy of the top of the Mamuniyat reservoir mapping reduce the risk of drilling the shaly facies of Bir Tlacsin and provide a better estimate of the reservoir reserve.
Good Daphnia parents do not control the offspring microbiome

AbstractIn Focus: Mushegian, A. A., Walser, J. ‐C., Sullam, K. E., & Ebert, D. (2018). . Journal of Animal Ecology, 87, 400–413. https://doi.org/10.1111/1365-2656.12709.All animals are colonized by micro‐organisms, most of which are benign or beneficial. Where do these micro‐organisms come from? Theory predicts that micro‐organisms which are transmitted vertically from parent to offspring are especially likely to be beneficial to the host, while horizontally acquired micro‐organisms are opportunistic and more variable in their impact on host performance. In this issue, Mushegian et al. () investigate the source of bacteria that are required for the growth and development of Daphnia water fleas to reproductive adults. They find that, although vertically transmitted bacteria can occur in the capsule enclosing the Daphnia eggs, the micro‐organisms that promote Daphnia performance are associated with the external surface of the capsule and are of likely environmental origin. This mode of transmission may be adaptive for Daphnia because, linked to the longevity and capacity for long‐distance dispersal of these eggs, the environmental circumstances encountered by parent and offspring may be different; with the implication, the parental micro‐organisms may not be optimal for the offspring. This study demonstrates that, although some animals require symbioses with specific coevolved, vertically transmitted microbial symbionts, other animals have evolved dependence on taxonomically variable micro‐organisms of environmental origin.

SummaryFungi are prolific producers of natural products routinely screened for biotechnological applications, and those living endophytically within plants attract particular attention because of their purported chemical diversity. However, the harnessing of their biosynthetic potential is hampered by a large and often cryptic phylogenetic and ecological diversity, coupled with a lack of large‐scale natural products' dereplication studies. To guide efforts to discover new chemistries among root‐endophytic fungi, we analyzed the natural products produced by 822 strains using an untargeted UPLC‐ESI‐MS/MS‐based approach and linked the patterns of chemical features to fungal lineages. We detected 17 809 compounds of which 7951 were classified in 1992 molecular families, whereas the remaining were considered unique chemistries. Our approach allowed to annotate 1191 compounds with different degrees of accuracy, many of which had known fungal origins. Approximately 61% of the compounds were specific of a fungal order, and differences were observed across lineages in the diversity and characteristics of their chemistries. Chemical profiles also showed variable chemosystematic values across lineages, ranging from relative homogeneity to high heterogeneity among related fungi. Our results provide an extensive resource to dereplicate fungal natural products and may assist future discovery programs by providing a guide for the selection of target fungi.

Published: February 2018

SummaryIt is unknown whether bacterioplankton and biofilm communities are structured by the same ecological processes, and whether they influence each other through continuous dispersal (known as mass effects). Using a hierarchical sampling approach we compared the relative importance of ecological processes structuring the dominant fraction (relative abundance ≥0.1%) of bacterioplankton and biofilm communities from three microhabitats (open water, Nuphar and Phragmites sites) at within‐ and among‐pond scale in a set of 14 interconnected shallow ponds. Our results demonstrate that while bacterioplankton and biofilm communities are highly distinct, a similar hierarchy of ecological processes is acting on them. For both community types, most variation in community composition was determined by pond identity and environmental variables, with no effect of space. The highest β‐diversity within each community type was observed among ponds, while microhabitat type (Nuphar, Phragmites, open water) significantly influenced biofilm communities but not bacterioplankton. Mass effects among bacterioplankton and biofilm communities were not detected, as suggested by the absence of within‐site covariation of biofilm and bacterioplankton communities. Both biofilm and plankton communities were thus highly structured by environmental factors (i.e., species sorting), with among‐lake variation being more important than within‐lake variation, whereas dispersal limitation and mass effects were not observed.

AimAcute calculous cholecystitis is a frequent complication of gallstones that can manifest in up to 10–15 per cent of previously asymptomatic patients. Current guidelines recommend laparoscopic cholecystectomy as the gold standard treatment; however, the presence of surgery risk factors might compel physicians to opt for conservative treatment, which is often associated with longer hospital stay. Home hospitalization could be an alternative to inpatient stay for these patients.Patients and MethodsThe present study was a retrospective analysis of data from a prospective patient single‐centre registry. Data from 915 patients with mild or moderate acute calculous cholecystitis, who presented in the Department of General Surgery of our hospital between 2010 and 2015, were analysed. The variables included grade of acute cholecystitis, type of treatment, use of antibiotics, inpatient stay, stay in hospital‐at‐home, complications, mortality, readmissions and relapse.ResultsA total of 147 (16 per cent) patients were referred to hospital‐at‐home, while the rest completed their treatment in the hospital ward. There were no significant differences between the home hospitalization and conventional hospitalization groups in the rates of complications, mortality, readmissions, relapse and length of antibiotherapy. Home hospitalization was associated with shorter inpatient stay, but longer total hospitalization, likely due to a prolonged follow up by the home care unit.ConclusionsHome hospitalization is an effective and safe alternative to conventional hospitalization, as it provides hospital‐level care and reduces the number of admissions and length of inpatient stay. The timely referral of patients to other levels of assistance, such as primary care, is needed to ensure economic benefits of home hospitalization programmes.
Producing Global Governance in the Global Factory: Markets, Politics, and Regulation
Authors: Haufler Virginia 
Published: February 2018

AbstractCoen and Pegram challenge us to integrate global governance theorising in ways that are pragmatic, policy‐oriented and interdisciplinary. One of the most prominent arenas for pursuing this challenge is through a focus on governing transnational production through voluntary and regulatory approaches. This focus directs attention to the structure and relationships within global value chains which influence the problems, actors, and mechanisms of global governance. Future research needs to explore how multiple governance initiatives within an industry interact, how issue boundaries evolve and change, the local implementation of global rules, and the relationships that shape governance outcomes.
Towards a Third Generation of Global Governance Scholarship
Authors: Coen David , Pegram Tom 
Published: February 2018

AbstractGlobal governance is widely viewed as in crisis. Deepening interdependence of cross‐border activity belies the relative absence of governance mechanisms capable of effectively tackling major global policy challenges. Scholars have an important role to play in understanding blockages and ways through. A first generation of global governance research made visible an increasingly complex and globalising reality beyond the interstate domain. A varied second generation of scholarship, spanning diverse subfields, has built upon this ‘signpost scholarship’ to generate insight into efforts to manage, bypass and even – potentially – transcend multilateral gridlock to address pressing transboundary problems. This article plots a course towards a ‘third generation’ of global governance research, serving to also introduce a special section which brings together leading scholars in the field of global governance, working across theoretical, analytical and issue‐area boundaries. This collaborative endeavour proposes to advance a convergence, already underway, across a theoretically and empirically rich existing scholarship, distinguished by a concern for the complexity of global public policy delivery.
Regional Contributions to Global Migration Governance: Introduction
Authors: Larik Joris , Sahoo Niranjan 
Published: February 2018

AbstractThe European migration crisis and the ongoing Rohingya refugee surge from Myanmar to Bangladesh have brought back the focus on migration governance and underlying policy challenges governing the issue. Many questions remain on how to properly manage mass migration flows. In particular, policy makers continue to face the challenge of respecting international commitments such as the 1951 Refugee Convention and its 1967 Protocol while at the same time mitigating political backlash promoted by a sense of loss of control and overburdening in receiving states. The present special section contributes to the ongoing debate in two ways. First, it homes in on regional perspectives on global migration governance with a view to fostering common approaches and better burden sharing. Second, the special section looks not only at Europe and its ‘new governance’ model, but also at South America's ‘emerging resettlement countries’ and the potential for enhanced inter‐regional cooperation between South Asia and Europe. In doing so, it puts the European crisis into a broader perspective and points to untapped potential of regional and inter‐regional approaches around the world.

AbstractAimUterine adenosarcoma is a rare malignancy with limited cohort data in Asian countries. This study evaluated the clinicopathologic features of Japanese patients with uterine adenosarcoma and their potential treatment challenges.MethodsA retrospective chart review was performed at the National Cancer Center Hospital, Japan from 2000 to 2016. A literature search for Japanese cases of uterine adenosarcoma was conducted using PubMed, Japanese Central Review of Medicine, and the Annual of Pathological Autopsy Cases in Japan. Only histologically confirmed cases of uterine adenosarcoma were included. All collected data were analyzed.ResultsA total of 110 cases was identified (6 from our hospital and 104 from the literature review). Most baseline characteristics were similar to those reported in western countries. Death due to the disease was observed in 34% (29/86) of patients, whereas patients with stage IA disease showed a 13% (4/30) recurrence rate and a 3.3% (1/30) mortality rate. Preoperative radiological and pathological examinations occasionally failed to help reach the correct diagnosis. In cases of sarcomatous overgrowth, the recurrence and mortality rates were 45% (9/20) and 35% (7/20), respectively. Distant recurrence occurred in 44% (12/27) of cases, 75% of which included lung metastasis.ConclusionsThis study showed the clinicopathologic features of Japanese patients with uterine adenosarcoma and suggested potential solutions for improving prognosis including early treatment based on a timely diagnosis, the development of effective adjuvant therapy for patients at high risk of recurrence, and optimal follow‐up focusing on late recurrence and lung metastasis.
Laparoscopic surgery with urinary tract reconstruction and bowel endometriosis resection for deep infiltrating endometriosis
Authors: Ota Yoshiaki , Andou Masaaki , Ota Ikuko 
Published: February 2018

AbstractDeep infiltrating endometriosis (DIE) is the most severe form of endometriosis. It causes chronic pelvic pain, severe dysmenorrhea, deep dyspareunia, dyschezia, and dysuria, markedly impairing the quality of life of women of reproductive age. A number of randomized controlled trials on surgical and medical treatments to reduce the pain associated with endometriosis have been reported, but few have focused on this in DIE. DIE causes not only pain but also functional invasion to the urinary organs and bowel, such as hydronephrosis and bowel stenosis. In addition to DIE resection, surgical treatment involves adhesion separation as well as resection and reconstruction of the urinary organs and bowel; high‐level skills are required. The severity of DIE should be evaluated preoperatively as accurately as possible. Using ENZIAN in conjunction with the AFS (The revised American Fertility Society classification of endometriosis) classification makes a more detailed assessment of DIE possible. The operative procedures used for laparoscopic resection of urinary DIE and reconstruction of the urinary organs are chosen based on the type of lesion (intrinsic/extrinsic) and length of stenosis. In addition to ureteroneocystostomy, the psoas bladder hitch and Boari bladder flap procedures are applied when necessary to extend the urinary tract. Bowel resection for bowel endometriosis is classified into classic segmental resection and conservative approaches (shaving/discoid). When these procedures are employed, it is advisable to work in consultation with urologists and gastroenterologists and to inform the patients of the associated risks and outcomes. Furthermore, postoperative medication is essential because it is difficult to conduct repeated surgeries.
