Informal Social Networks as Intermediaries in Foreign Markets
Authors: Apaydin Marina , Thornberry Jon , Sidani Yusuf M. 
Published: July 2020

ABSTRACTWe investigate how informal social networks can assist multinational firms in their internationalization strategy. We propose a refinement of the Uppsala internalization model (Johanson & Vahne, 2009) grounded in network theory, by developing an intermediate position between an ‘insider’ and an ‘outsider’ for conditions when the transformation of an outsider into an insider is limited by institutional constraints. An intermediary position represents one of the sides of ‘patron-client’ informal networks (Denoeux, 1993) whereby the other side is represented by the ‘insider’. We argue that this setup would help mitigate the Liability of Outsidership (Johanson & Vahne, 2009), a replacement of the Liability of Foreignness (Hymer, 1976; Zaheer, 1995), in the modern networked business world. We contextualize our proposition for the case of Iran, a large rising West-Asian economy with known institutional limitations, and suggest that the informal network of local merchants (bazaaries) could play an important intermediary role in Multinational Enterprises (MNEs) internationalization process. We review the history ofbazaariesand make a series of propositions exemplifying possible ways informal networks could influence the internationalization process. In addition to re-affirming the importance of the MNE country of origin (emerging markets, and low psychic distance with Iran), we propose that an intermediary of the Iranianbazaarieswill have a positive impact on performance and survival of the MNE's subsidiary in Iran, especially in the case of incongruence of MNE's leadership with Shi'a Islam. Additionally, we suggest that employing the Iranian diaspora may also improve subsidiary performance and survival.

Published: July 2020

ABSTRACTConnecting calendar ages to radiocarbon (14C) ages, i.e. constructing a calibration curve, requires14C samples that represent, or are closely connected to, atmospheric14C values and that can also be independently dated. In addition to these data, there is information that can serve as independent tests of the calibration curve. For example, information from ice core radionuclide data cannot be directly incorporated into the calibration curve construction as it delivers less direct information on the14C age–calendar age relationship but it can provide tests of the quality of the calibration curve. Furthermore, ice core ages on14C-dated volcanic eruptions provide key information on the agreement of ice core and radiocarbon time scales. Due to their scarcity such data would have little impact if directly incorporated into the calibration curve. However, these serve as important “anchor points” in time for independently testing the calibration curve and/or ice-core time scales. Here we will show that such information largely supports the new IntCal20 calibration record. Furthermore, we discuss how floating tree-ring sequences on ice-core time scales agree with the new calibration curve. For the period around 40,000 years ago we discuss unresolved differences between ice core10Be and14C records that are possibly related to our limited understanding of carbon cycle influences on the atmospheric14C concentration during the last glacial period. Finally, we review the results on the time scale comparison between the Greenland ice-core time scale (GICC05) and IntCal20 that effectively allow a direct comparison of14C-dated records with the Greenland ice core data.
Radiocarbon Dating of Mortars and Charcoals from Novae Bath Complex: Sequential Dissolution of Historical and Experimental Mortar Samples with Pozzolanic Admixture
Authors: Michalska Danuta , Mrozek-Wysocka Małgorzata 
Published: July 2020

ABSTRACTCarbonaceous mortars from Novae (Bulgaria) contain local loess, crushed bricks and ceramic dust (pozzolanic materials). The reaction between lime and pozzolanic additives occurs easily and affects the rate and course of leaching reaction of carbonates in orthophosphoric acid during the sample pretreatment for dating. The composition of the Bulgarian mortars does not allow for unambiguous conclusions about chronology, but together with the observations of experimental mortars, gives new guidelines in terms of pozzolanic mortar application for dating. The presented research illustrates the possible reasons of difficulties with obtaining the appropriate portion of gas for radiocarbon (14C) measurement. To verify the relative chronology of legionary baths complex in Novae, the charcoals samples were also dated in addition to the mortar.
Speeding Up On-Line Route Scheduling for an Autonomous Robot Through Pre-Built Paths
Authors: Alves Raul , de Morais Josué Silva , Yamanaka Keiji 
Published: July 2020

SUMMARYToday, robots can be found helping humans with their daily tasks. Some tasks require the robot to visit a set of locations in the environment efficiently, like in the Traveling Salesman Problem. As indoor environments are maze-like areas, feasible paths connecting locations must be computed beforehand, so they can be combined during the scheduling, which can be impracticable for real-time applications. This work presents an on-line Route Scheduling supported by a Fast Path Planning Method able to adjust pre-built paths. Experiments were carried out with virtual and real robots to evaluate time and quality of tours.
Aerosol and environmental surface monitoring for SARS-CoV-2 RNA in a designated hospital for severe COVID-19 patients

Published: July 2020

Abstract
There is limited information concerning the viral load of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in aerosols deposited on environmental surfaces and the effectiveness of infection prevention and control procedures on eliminating SARS-CoV-2 contamination in hospital settings. We examined the concentration of SARS-CoV-2 in aerosol samples and on environmental surfaces in a hospital designated for treating severe COVID-19 patients. Aerosol samples were collected by a microbial air sampler, and environmental surfaces were sampled using sterile premoistened swabs at multiple sites. Ninety surface swabs and 135 aerosol samples were collected. Only two swabs, sampled from the inside of a patient's mask, were positive for SARS-CoV-2 RNA. All other swabs and aerosol samples were negative for the virus. Our study indicated that strict implementation of infection prevention and control procedures was highly effective in eliminating aerosol and environmental borne SARS-CoV-2 RNA thereby reducing the risk of cross-infection in hospitals.
Can mandible morphology help predict feeding habits in Antarctic amphipods?
Authors: Michel Loïc N. , Nyssen Fabienne L. , Dauby Patrick , Verheye Marie 
Published: July 2020

AbstractIn Antarctica, amphipods form a highly diverse group, occupy many different ecological niches and hold an important place in food webs. Here, we aimed to test whether differences in Antarctic amphipod feeding habits were reflected in their mandible morphology, and if mouthpart specialization could be used to describe amphipod trophic ecology. To do so, we compared mandible morphology in nine species spanning seven families and five functional groups (grazers, suspension feeders, generalist predators, specialist predators and scavengers). Mandible morphology adequately depicted some aspects of amphipod trophic ecology, such as the trophic level at which animals feed or their degree of dietary specialization. On the other hand, links between mandible morphology and amphipod diet were seldom unambiguous or straightforward. Similar adaptations were found in distinct functional groups. Conversely, mandible morphology could vary within a single functional group, and phylogenetic effects sometimes complicated the interpretation of form-function relationships. Overall, mandible morphology on its own was generally not sufficient to precisely predict amphipod feeding strategies. However, when combined with other methods (e.g. gut contents, trophic markers), it constitutes a valuable source of information for integrative studies of amphipod ecological diversity in the Southern Ocean.

Published: July 2020

AbstractIntroduction:The Fontan procedure is the final stage of surgical palliation for the children with functionally single ventricle anatomy. The post-operative medical management of this patient population can be variable and hospital length of stay prolonged. The purpose of this quality improvement project was to determine if the implementation of an evidence-based clinical pathway for post-operative management of the Fontan patient at a large Midwestern academic paediatric medical centre would standardise care and decrease length of stay.Materials and methods:The clinical pathway was developed using key components from three published pathways for the Fontan procedure from other paediatric institutions across the United States. Components of the clinical pathway included (1) supplemental oxygen until pleural drainage tubes are removed, (2) fluid restriction to 80% daily maintenance and a prescribed low-fat diet, (3) aggressive and standardised diuretic therapy while inpatient and (4) central venous access. The pathway was trialed using Plan-Do-Study-Act cycles in 2016, implemented in 2017 and sustained in 2018–2019. A retrospective electronic medical record review was performed to compare key outcomes from pre-pathway (2014–2015, 37 patients) with post-pathway implementation (2017–2018, 30 patients).Results:Adherence to the pathway was nearly 100% with a statistically significant decrease in length of stay from 12 to 9 days (p = 0.007) and no increase in readmissions.Conclusion:Standardising care can improve clinical and financial outcomes for the Fontan patient population without negatively impacting quality of care, thus providing a positive benefit to the healthcare institution, industry and patient.
To what extent could cardiovascular diseases be reduced if Germany applied fiscal policies to increase fruit and vegetable consumption? A quantitative health impact assessment
Authors: Schönbach Johanna-Katharina , Lhachimi Stefan K 
Published: July 2020

AbstractObjective:This study aimed to dynamically model and quantify expected health effects of four scenarios: (i) a reference scenario with an unchanged fruit and vegetable intake, (ii) the removal of value-added tax (VAT) on fruits and vegetables, (iii) the implementation of a 20 % subsidy on fruits and vegetables and (iv) a guideline scenario with a population-wide fruit and vegetable intake of five portions per day.Design:Baseline fruit and vegetable intake data was derived from the GEDA 2012 study. We used price elasticities for Germany to calculate the change in fruit and vegetable consumption under the zero VAT and the 20 % subsidy scenario. All scenarios were modelled over a 10-year projection period using DYNAMO-HIA.Setting:Germany.Participants:A projected real-life population.Results:Cumulated over the 10-year projection period, an estimated 4450 incident ischaemic heart disease (IHD) cases, 7010 stroke cases and 13 960 deaths would be prevented under the zero VAT scenario. Under the 20 % subsidy scenario, 17 990 incident IHD cases, 27 390 stroke cases and 54 880 deaths would be averted. Although this corresponds to only a fraction of the incidents that would occur under the reference scenario, the averted cases translate to 2 % (for the zero VAT scenario) and 9 % (for the 20 % subsidy scenario) of IHD, stroke and death cases that would be prevented if the whole population consumed the recommended five portions of fruits and vegetables per day.Conclusions:Fiscal policies on fruits and vegetables provide a non-negligible step towards the removal of the health burden induced by low fruit and vegetable intake.

Published: July 2020

AbstractObjective:To determine the reliability of streamlined data-gathering techniques for examining the price and affordability of a healthy (recommended) and unhealthy (current) diet. We additionally estimated the price and affordability of diets across socio-economic areas and quantified the influence of different pricing scenarios.Design:Following the Healthy Diets Australian Standardised Affordability and Pricing (ASAP) protocol, we compared a cross-sectional sample of food and beverage pricing data collected using online data and phone calls (lower-resource streamlined techniques) with data collected in-store from the same retailers.Setting:Food and beverage prices were collected from major supermarkets, fast food and alcohol retailers in eight conveniently sampled areas in Victoria, Australia (n72 stores), stratified by area-level deprivation and remoteness.Participants:This study did not involve human participants.Results:The biweekly price of a healthy diet was on average 21 % cheaper ($596) than an unhealthy diet ($721) for a four-person family using the streamlined techniques, which was comparable with estimates using in-store data (healthy: $594, unhealthy: $731). The diet price differential did not vary considerably across geographical areas (range: 18–23 %). Both diets were estimated to be unaffordable for families living on indicative low disposable household incomes and below the poverty line. The inclusion of generic brands notably reduced the prices of healthy and unhealthy diets (≥20 %), rendering both affordable against indicative low disposable household incomes. Inclusion of discounted prices marginally reduced diet prices (3 %).Conclusions:Streamlined data-gathering techniques are a reliable method for regular, flexible and widespread monitoring of the price and affordability of population diets in areas where supermarkets have an online presence.
Trade Impacts of Fossil Fuel Subsidies
Authors: Moerenhout Tom 
Published: July 2020

AbstractThis article introduces the various trade impacts of fossil fuel subsidies. There are large direct and pass-through trade impacts. Direct trade impacts are found when producer subsidies affect the markets for crude energy products such as crude oil, natural gas, and coal. Direct trade impacts are also found when consumer subsidies decrease the input costs of various industries, whether they refine crude products into energy carriers (e.g. gasoline, electricity) or they use energy products to produce non-energy products (e.g. iron and steel, plastics). Pass-through trade impacts are found when upstream fossil fuel subsidies lead to a lower-cost product that is then used in downstream production processes. We find that markets for fossil fuels, refined energy products and energy-intensive products are enormous. In 2018, crude fossil fuel exports were worth at least US$1.3 trillion, petroleum product exports at least US$800 billion, and exports of energy-intensive goods at least US$1.3 trillion. Their trade volume and export value, as well as their competition density highlight that fossil fuel subsidies have a direct impact on who wins and who loses in terms of market share.
Institutions, the social capital structure, and multilevel marketing companies
Authors: Lofthouse Jordan K. , Storr Virgil Henry 
Published: July 2020

AbstractIn multilevel marketing companies (MLMs), member-distributors earn income from selling products and recruiting new members. Successful MLMs require a social capital structure where members can access and mobilize both strong and weak social ties. Utah has a disproportionate share of MLM companies located in the state and a disproportionate number of MLM participants. We argue that Utah's dominant religious institutions have led to the emergence of a social capital structure, making MLMs particularly viable. Utah is the most religiously homogeneous state; roughly half its population identifies as members of the Church of Jesus Christ of Latter-day Saints (LDS Church). The LDS Church's institutions foster a social capital structure where (almost all) members have access to and can leverage social capital in all its forms. LDS institutions encourage members to make meaningful social connections characterized by trust and reciprocity with other church members in local neighborhoods and across the world.
Fitting multi-population mortality models to socio-economic groups
Authors: Wen Jie , Cairns Andrew J.G. , Kleinow Torsten 
Published: July 2020

AbstractWe compare results for 12 multi-population mortality models fitted to 10 distinct socio-economic groups in England, subdivided using the Index of Multiple Deprivation. Using the Bayes Information Criterion to compare models, we find that a special case of the common age effect (CAE) model fits best in a variety of situations, achieving the best balance between goodness of fit and parsimony. We provide a detailed discussion of key models to highlight which features are important. Group-specific period effects are found to be more important than group-specific age effects, and non-parametric age effects deliver significantly better results than parametric (e.g. linear) age effects. We also find that the addition of cohort effects is beneficial in some cases but not all. The preferred CAE model has the additional benefit of being coherent in the sense of Hyndman et al. ((2013) Demography50(1), 261–283); some of the other models considered are not.
Supported cognitive-behavioural therapy self-help versus treatment-as-usual for depressed informal caregivers of stroke survivors (CEDArS): feasibility randomised controlled trial
Authors: Farrand Paul , Woodford Joanne , Coumoundouros Chelsea , Svedin Frida 
Published: July 2020

Abstract
Demands placed on informal caregivers can result in an increased likelihood of experiencing common mental health difficulties that may affect their ability to undertake the caring role. Currently, however, few evidence-based interventions have been specifically developed for informal caregivers and available interventions are difficult to access. The Improving Access to Psychological Therapies (IAPT) programme aims to improve access to evidence-based psychological therapies for all groups and may therefore present an opportunity to meet informal caregiver needs. Located within the MRC Complex Intervention Framework, a Phase II feasibility randomised controlled trial (RCT) examines key methodological, procedural and clinical uncertainties associated with running a definitive Phase III RCT of an adapted written cognitive behavioural therapy (CBT) self-help intervention for informal caregivers of stroke survivors. Recruitment was low despite different recruitment strategies being adopted, highlighting significant challenges moving towards a Phase III RCT until resolved. Difficulties with study recruitment may reflect wider challenges engaging informal caregivers in psychological interventions and may have implications for IAPT services seeking to improve access for this group. Further attempts to develop a successful recruitment protocol to progress to a Phase III RCT examining effectiveness of the adapted CBT self-help intervention should be encouraged.

Higher maternal weight is related to poorer fetal autonomic function

Published: July 2020

AbstractMaternal obesity is an established risk factor for poor infant neurodevelopmental outcomes; however, the link between maternal weight and fetal development in utero is unknown. We investigated whether maternal obesity negatively influences fetal autonomic nervous system (ANS) development. Fetal heart rate variability (HRV) is an index of the ANS that is associated with neurodevelopmental outcomes in the infant. Maternal–fetal magnetocardiograms were recorded using a fetal biomagnetometer at 36 weeks (n = 46). Fetal HRV was represented by the standard deviation of sinus beat-to-beat intervals (SDNN). Maternal weight was measured at enrollment (12–20 weeks) and 36 weeks. The relationships between fetal HRV and maternal weight at both time points were modeled using adjusted ordinary least squares regression models. Higher maternal weight at enrollment and 36 weeks were associated with lower fetal HRV, an indicator of poorer ANS development. Further study is needed to better understand how maternal obesity influences fetal autonomic development and long-term neurodevelopmental outcomes.
One Flood Is Not Enough: Pool‐Riffle Self‐Maintenance Under Time‐Varying Flows and Nonequilibrium Multifractional Sediment Transport

Published: July 2020

AbstractThe interaction of sediment supply and hydrographs can affect, on a mesoscale, geomorphic features like pools and riffles, which are fundamental units of many gravel bed rivers. In the past decades, different hypotheses have been developed to characterize the hydrodynamics of pool‐riffle sequences; however, most of the previous studies considered equilibrium or near‐equilibrium sediment transport conditions. Here we investigate the stability of pools and riffles during a sequence of different hydrographs representative of a natural flow regime, without satisfying the equilibrium sediment transport condition. In the current study, the effects of bed geometry, sediment sorting and hydrograph duration, are explained and quantified. The results show that under nonequilibrium conditions, the reversal episodes are not always competent enough for complete self‐maintenance during a single flood. However, width variations and grain sorting effects prevented the pools to be completely filled up with the upstream sediment supply. Hydrograph duration had a significant role in the riffle bed geometry. Even though a single flood (irrespective of the magnitude) was not competent enough to restore the pool‐riffle feature, a sequence of floods progressively improved conditions for self‐maintenance. These findings can bring more insight into flow management strategies, in terms of the importance of multiple sequential floods for restoring rivers with high sediment supply.
