Muscle and nerve net organization in stalked jellyfish (Medusozoa: Staurozoa)
Authors: Westlake Hannah E. , Page Louise R. 
Published: October 2016

ABSTRACTStaurozoan cnidarians display an unusual combination of polyp and medusa characteristics and their morphology may be informative about the evolutionary origin of medusae. We studied neuromuscular morphology of two staurozoans, Haliclystus ‘sanjuanensis’ and Manania handi, using whole mount immunohistochemistry with antibodies against FMRFamide and α‐tubulin to label neurons and phalloidin to label muscles. All muscles appeared to lack striations. Longitudinal interradial muscles are probable homologues of stalk muscles in scyphopolyps, but in adult staurozoans they are elaborated to inwardly flex marginal lobes of the calyx during prey capture; these muscles are pennate in M. handi. Manubrial perradial muscles, like the manubrium itself, are an innovation shared with pelagic medusae and manubrial interradial muscles are shared with scyphozoan ephyra. Marginal muscles of M. handi displayed occasional synchronous contraction reminiscent of a medusa swim pulse, but contractions were not repetitive. The nerve net in both species showed regional variation in density and orientation of neurons. Some areas labeled predominantly by α‐tubulin antibodies (exumbrellar epidermis), other areas labeled exclusively by FMRFamide antibodies (dense plexus of neurites surrounding the base of secondary tentacles, neuronal concentration at the base of transformed primary tentacles; gastrodermal nerve net), but most areas showed a mix of neurons labeled by these two antibodies and frequent co‐labeling of neurons. Transformed primary tentacles had a concentration of FMRFamide‐immunoreactive neurons at their base that was associated with a pigment spot in M. handi; this is consistent with their homology with rhopalia of medusae, which are also derived from primary tentacles. The muscular system of these staurozoans embodies characteristics of both scyphopolyps and pelagic medusae. However, their nerve net is more polyp‐like, although marginal concentrations of the net associated with primary and secondary tentacles may facilitate the richer behavioral repertoire of staurozoans relative to polyps of other medusozoans.

Authors: Zhou Li‐Xia , Dong Su‐Zhen , Zhang Ming‐Feng 
Published: October 2016

PurposeTo present three fetal vein of Galen aneurysmal malformations (VGAMs), which were diagnosed through magnetic resonance imaging (MRI), and highlight these cardiovascular findings.Materials and MethodsWe retrospectively reviewed three fetuses with VGAM at 31, 32, and 33 weeks of gestation. Feeding arteries and draining veins were observed by MRI. Secondary changes in the brain and high‐output heart failure caused by high blood flow in the lesion were evaluated. Two fetuses were born, and neonatal MRI was performed. One fetus was terminated.ResultsA characteristic dilated structure in the midline of the brain presented in each fetus. The arteriovenous fistula led to anatomical brain changes such as in the hydrocephalus, dilated feeding vessels (one or more), jugular vein, and/or superior vena cava. Substantial brachiocephalic vessel dilation was observed in two fetuses. Following parturition, one baby had neonatal asphyxia and sinus thrombosis, and MRI revealed hypoxic‐ischemic encephalopathy. Cardiomegaly was detected in all three cases.ConclusionWith a large field of view, fetal MRI can observe brain VGAM, as well as the heart and affected large vessels. It can determine hydrocephalus, ischemia, intracranial hemorrhage, and sinus thrombosis. Providing such information on the infant's entire body can aid clinicians in determining the most appropriate treatment.Level of Evidence: 4J. Magn. Reson. Imaging 2017;46:1535–1539.

ABSTRACTThe objectives of this study were to investigate the trend in annual precipitation, sunshine duration, wind speed (u
2), and annual and monthly minimum temperature (T
min), maximum temperature (T
max), and relative humidity (RH) and the adaptation strategies for the Senegal River Basin. Annual precipitation, T
min, T
max, RH, sunshine duration, and u
2 for the period of 1950–2000 recorded at St‐Louis, Bakel, Dagana, Fanaye, Podor, and Matam have been analysed using the Mann–Kendall test and Sen's slope estimator. Annual precipitation varied with location from 900 mm registered in 1967 at Bakel to 32 mm obtained at Dagana in 1986. A significant decreasing trend (p < 0.001) in precipitation was observed at Podor, Dagana, Matam, Bakel, and St‐Louis. A non‐significant decreasing trend in annual precipitation was observed at Fanaye Dieri. There was a significant increasing trend (p < 0.001) in T
max and T
min at all locations. Sunshine duration had a significant decreasing trend at Podor, Matam, and St‐Louis at the rate of 0.27, 0.28, and 0.35 h decade−1, respectively. RH and u
2 have differences in their trends, with the first one showing a strong and significant decrease and u
2 with less significance in their trends. The trend analysis in the climate variables revealed a change in climate that necessitates some specific actions for resources management sustainability and conservation.
A cross‐sectional study of patient and provider perception of “cure” as a goal of cancer surgery
Authors: Winner Megan , Wilson Ana , Yahanda Alexander , Kim Yuhree , Pawlik Timothy M. 
Published: October 2016

Background and ObjectivePatients with advanced cancer often misperceive the purpose and likely effectiveness of cancer treatments. The aim of this study was to characterize patient and provider perceptions in the setting of surgery for potentially curable cancer.MethodsOne hundred and six patient‐surgeon dyads were surveyed about their expectations for upcoming surgery. Items scored using a Likert scale were compared using the Wilcoxon signed‐rank test.ResultsPatients and surgeons reported excellent communication and shared decision‐making. Patients more often than surgeons perceived that surgery was “Likely” or “Very Likely” to cure their cancer (86.0% vs. 72.0%, P = 0.011), extend their lives (94.0% vs. 82.0%, P = 0.007), and relieve cancer‐related symptoms (65.0% vs. 35.0%, P < 0.001). Patients less often felt that surgery would be associated with complications (33.0% vs. 48.0%, P = 0.016). Over half (53.9%) of patients believed that they were more likely to experience surgical cancer cure compared with someone else with the same diagnosis while 70.8% of surgeons declared a patient's relative chances of surgical cure “the same.”ConclusionsPatients with resectable lung and gastrointestinal cancers have more optimistic perceptions about the outcomes of an upcoming surgery than their surgeons, even in a setting of good communication and shared decision‐making.

Authors: Deckers Claudia , Schreuder Bart H.W. , Hannink Gerjon , de Rooy Jacky W.J. , van der Geest Ingrid C.M. 
Published: October 2016

Background and ObjectivesBoth enchondroma and atypical cartilaginous tumors (ACT) are not considered malignant, so inactive and asymptomatic tumors might not need surgery. To the best of our knowledge, this is the first study that has been done to evaluate the natural course of conservative‐treated enchondroma and ACT in the long bones.MethodsFor this retrospective study, we analyzed the results of patients in whom we refrained from surgery and only regularly performed radiological follow‐up of the tumor. Minimal follow‐up after initial diagnosis was 24 months.ResultsForty‐nine patients were included in this study. Eight out of forty‐nine cases received surgical treatment during follow‐up of the tumor. The reasons for this surgery were radiologic growth of the tumor in two cases, pain in one case, patient request in three cases, another indication for surgery in the same limb in two cases.ConclusionIn this small series of conservatively treated enchondroma and ACT, only 6% of the patients had a medical indication for surgery. This study shows that indication for surgery should be discussed more thoroughly. Based on our results, we would recommend annual radiologic follow‐up for asymptomatic enchondroma or ACT in the long bones, irrespective of tumor size. J. Surg.

Temperature‐induced structural changes in even‐odd nylons with long polymethylene segments
Authors: Olmo Cristian , Rota Ramon , Carlos Martínez Juan , Puiggalí Jordi , Franco Lourdes 
Published: October 2016

ABSTRACTStructural transitions of nylons 8 9 and 12 9 heating and cooling processes were investigated using calorimetric, spectroscopic during and real time X‐ray diffraction data. These even‐odd nylons had three polymorphic forms related to structures where hydrogen bonds were established in two planar directions. Heating processes showed a first structural transition at low temperature where the two strong reflections related to the packing mode of the low temperature structure (form I) disappeared instead of moving together and merging into a single reflection, as observed for conventional even‐even nylons. The high temperature structure corresponded to a typical pseudohexagonal packing (form III) attained after the named Brill transition temperature. Structural transitions were not completely reversible since an intermediate structure (form II) became clearly predominant at room temperature in subsequent cooling processes.A single spherulitic morphology with negative birefringence and a flat‐on edge‐on lamellar disposition was obtained when the two studied polyamides crystallized from the melt state. Kinetic analyses indicated that both nylons crystallized according to a single regime and a thermal nucleation. Results also pointed out a secondary nucleation constant for nylon 12 9 higher than that for nylon 8 9, suggesting greater difficulty in crystallizing when the amide content decreased. © 2016 Wiley Periodicals, Inc.

Strategic Sustainability Procedures: Focusing Business Strategic Planning on the Socio‐Ecological System in an Island Context
Authors: Telesford John N. , Strachan Peter A. 
Published: October 2016

AbstractThis article illustrates how strategic sustainability procedures (SSPs) can be applied in the tourism accommodation sector in the Caribbean island of Grenada. SSPs are conceptualized from an adapted framework for strategic sustainable development (FSSD). Part 1 of the adapted FSSD defines the vision for the sustainability of the socio‐ecological system or a vision for sustainability. Part 2 describes sustainable development processes and actions that businesses can implement to move towards the vision. These two systems exchange materials, energy and waste flows (MEWFs). The article shows how strategic actions to optimize MEWFs between the systems can lead to the vision for sustainability. Utilizing a mixed methods approach, ‘visioning and vision linking’, ‘developing sector strategic actions’ and ‘monitoring and evaluation’ were formulated into SSPs in an island context.

Community‐Based Monitoring and Protected Areas: Towards an Inclusive Model
Authors: Ortega‐Álvarez Rubén , Sánchez‐González Luis Antonio , Valera‐Bermejo Adriana , Berlanga‐García Humberto 
Published: October 2016

AbstractOperational, financial and conceptual issues hinder protected area (PA) conservation goals, particularly in mega‐diverse countries where highly impoverished human communities live within their boundaries. We (a) highlight the relevance of community‐based biological monitoring for linking local communities with PAs to enhance their functionality, achieve conservation objectives and promote social development, (b) pinpoint key elements for establishing community‐based biological monitoring programs and (c) propose an inclusive model for PAs where the active participation of communities is essential. Through community‐based biological monitoring, PAs enhance the performance of species monitoring, surveillance, development and operation of management plans, local communities' engagement in conservation, and research activities. In turn, communities increase their knowledge on local natural resources, and acquire abilities needed to identify and quantify them, and ultimately lead to more informed decisions regarding their management and conservation. It is essential to consider PAs and local communities as a unit to achieve an integrated conservation approach. Copyright © 2016 John Wiley & Sons, Ltd and ERP Environment
A Framework for Sustainable Strategic Planning of Water Demand and Supply in Arid Regions
Authors: Banihabib Mohammad Ebrahim , Hashemi Farkhondeh , Shabestari Mohammad Hadi 
Published: October 2016

AbstractThis paper addresses strategic planning of water resources in an arid region based on sustainable development criteria (SDC). Three multi‐criteria decision‐making (MCDM) models, simple additive weighting (SAW), the analytic hierarchy process (AHP) and the Technique for Order Preference by Similarity to Ideal Solution (TOPSIS), were used for detailed ranking of the strategies and assessing the result of the Quantitative Strategic Planning Matrix (QSPM). The results of the MCDM models were not identical, so we used aggregation approaches including mean rank, Borda count and Copeland's methods to integrate rankings. The results of sensitivity analysis revealed that all MCDM models were sensitive to the social and environmental criteria. The SAW and AHP models were also less sensitive to changes in criterion weights than the TOPSIS model. The results showed the priority of the MCDM models over QSPM analysis in incorporating SDC in detailed evaluation of the strategies. Copyright © 2016 John Wiley & Sons, Ltd and ERP Environment
Review of Barriers to Green Building Adoption
Authors: Darko Amos , Chan Albert P. C. 
Published: October 2016

AbstractThe need to implement sustainable development (SD) in the construction industry has given birth to the green building (GB) movement. GB is a promising construction approach through which the construction industry contributes to SD. However, the adoption of GB has been hampered in many parts of the world by numerous barriers. To date, no attention has been paid to the need to review existing knowledge of barriers affecting GB adoption. This paper presents a systematic review of literature on barriers to GB adoption published in academic journals. It has been found that lack of information, cost, lack of incentives, lack of interest and demand, and lack of GB codes and regulations are the most reported barriers in the literature. Recommendations are offered to overcome the barriers to facilitate the adoption of GB. This review provides a valuable reference for both industry practitioners and policy makers to implement GB. Moreover, a developed checklist of GB barriers in this paper can be useful to scholars for further empirical studies. Copyright © 2016 John Wiley & Sons, Ltd and ERP Environment
The Future of Sustainable Tourism in Developing Countries
Authors: Yfantidou Georgia , Matarazzo Michela 
Published: October 2016

AbstractThe term ‘green tourism’ is often used in conjunction with the desire for a balanced approach to tourism planning. ‘Green tourism’ is defined as tourism that enhances the local cultural elements, operating under the control of local communities, providing employment and maintaining the economic benefits within the local communities. In fact, the above definition is often poorly attested, since there are times when the economic benefits escape from local communities. For its part the tourist industry uses the term ‘green tourism’ as a message to tourists on energy saving, avoiding coastal pollution etc. Sometimes the same tourist businesses are accused of using the label ‘green’ primarily for marketing purposes. This paper shows that governments have a crucial role regarding encouragement to use cleaner technologies in the tourism sector and presenting different approaches for sustainability to be achieved in developing countries.

An empirical examination of vacillation theory
Authors: Kang Jingoo , Kang Ribuga , Kim Sang‐Joon 
Published: October 2016

Research summary: Since Nickerson and Zenger (2002) proposed how vacillation may lead to organizational ambidexterity, large‐sample empirical tests of their theory have been missing. In this paper, we empirically examine the performance implications of vacillation. Building upon vacillation theory, we predict that the frequency and scale of vacillation will have inverted U‐shaped relationships with firm performance. We test our hypotheses using patent‐based measures of exploration and exploitation in the context of technological innovation and knowledge search.Managerial summary: Firms often shift their focus on technological innovation and knowledge search from seeking new and novel knowledge (i.e., exploration) to extending and refining existing knowledge (i.e., exploitation) or vice versa. We examine how the frequency and scale of firms vacillating between exploration and exploitation may affect their performance. We find that both too infrequent or too frequent changes and a too small or too large scale of changes are not desirable. Copyright © 2016 John Wiley & Sons, Ltd.
Pattern‐based multi‐cloud architecture migration
Authors: Jamshidi Pooyan , Pahl Claus , Mendonça Nabor C. 
Published: October 2016

SummaryMany organizations migrate on‐premise software applications to the cloud. However, current coarse‐grained cloud migration solutions have made such migrations a non transparent task, an endeavor based on trial‐and‐error. This paper presents Variability‐based, Pattern‐driven Architecture Migration (V‐PAM), a migration method based on (i) a catalogue of fine‐grained service‐based cloud architecture migration patterns that target multi‐cloud, (ii) a situational migration process framework to guide pattern selection and composition, and (iii) a variability model to structure system migration into a coherent framework. The proposed migration patterns are based on empirical evidence from several migration projects, best practice for cloud architectures and a systematic literature review of existing research. Variability‐based, Pattern‐driven Architecture Migration allows an organization to (i) select appropriate migration patterns, (ii) compose them to define a migration plan, and (iii) extend them based on the identification of new patterns in new contexts. The patterns are at the core of our solution, embedded into a process model, with their selection governed by a variability model. Copyright © 2016 John Wiley & Sons, Ltd.
A low‐cost real‐time face tracking system for ITSs and SDASs
Authors: Liu Leyuan , Chen Jingying , Gao Changxin , Sang Nong 
Published: October 2016

SummaryIt is important to track people's face efficiently and accurately in many Intelligent Transportation Systems (ITSs) and Safety Driving Assistant Systems (SDASs). This paper presents a high‐performance and low‐cost real‐time face tracking system, which runs on general onboard computer with very low CPU consumption. The proposed face tracking system is composed of four modules: the motion detector, face detector, face tracker, and face validator. The motion detector extracts motion areas by using a spatial‐temporal bi‐differential method with a very low computational cost. The face detector integrates motions into a cascade face detection framework to reject most of non‐face scanning‐windows to ensure efficient face localization. The face tracker fuses motion feature with color feature to alleviate the drifting problem during tracking. The face validator builds face appearance models online and identifies each specific tracked face to avoid confusion. Experimental results on three challenging video sequences show that the proposed face tracking system outperforms the state‐of‐the‐art face tracker and consumes only 5–13% CPU resources of a low‐spec onboard computer while processing in real time.

Temporal patterns of induction and recovery of biomarker transcriptional responses to 4‐Nonylphenol and 17β‐estradiol in the estuarine arrow goby, Clevelandia ios
Authors: Johnson Kaitlin M. , Lema Sean C. 
Published: October 2016

ABSTRACTSeveral estuaries along the Pacific Ocean coast of North America were identified recently as having elevated 4‐nonylphenol (4‐NP) in sediments and biota, raising concerns about reproductive impacts for wildlife given 4‐NP's established estrogenic activity as an endocrine‐disrupting compound. Here we characterize 4‐NP mediated induction and recovery of estrogen‐sensitive gene transcripts in the arrow goby (Clevelandia ios), an intertidal fish abundant in estuarine mud flats on the west coast of North America. Male gobies were exposed to waterborne 4‐NP at 10 μg/L or 100 μg/L for 20 days followed by a 20 day depuration period. Additional males were treated with 17β‐estradiol (E2; 50 ng/L). 4‐NP at 100 μg/L elevated hepatic mRNAs encoding vitellogenins A (vtgA) and C (vtgC) and choriogenin L (chgL) within 72 h, and choriogenin H minor (chgHm) within 12 days. Hepatic mRNAs encoding estrogen receptor alpha (esr1) were also elevated after 12 days of 4‐NP exposure, but returned to pre‐exposure levels at 20 days even under continuing 4‐NP treatment. 4‐NP did not alter mRNA levels of estrogen receptor gamma (esr2a) in the liver, or of esr1, esr2a, and cytochrome P450 aromatase B (cyp19a1b) in the brain. The temporal pattern of initial induction for hepatic vtgA, vtgC, and chgL transcripts by 4‐NP mirrored the pattern by E2, while chgHm and esr1 mRNA induction by 4‐NP lagged 2–11 days behind the responses of these transcripts to E2. These findings establish 4‐NP concentration‐ and time‐dependent induction patterns of choriogenin and vitellogenin transcription following exposure to environmentally relevant 4‐NP concentrations, while concurrently demonstrating tissue‐specific induction patterns for esr1 by estrogenic compounds. © 2016 Wiley Periodicals, Inc.
