OPTIMAL INSURANCE CONTRACTS UNDER DISTORTION RISK MEASURES WITH AMBIGUITY AVERSION
Authors: Jiang Wenjun , Escobar-Anel Marcos , Ren Jiandong 
Published: May 2020

AbstractThis paper presents analytical representations for an optimal insurance contract under distortion risk measure and in the presence of model uncertainty. We incorporate ambiguity aversion and distortion risk measure through the model of Robert and Therond [(2014) ASTIN Bulletin: The Journal of the IAA, 44(2), 277–302.] as per the framework of Klibanoff et al. [(2005) A smooth model of decision making under ambiguity. Econometrica, 73(6), 1849–1892.]. Explicit optimal insurance indemnity functions are derived when the decision maker (DM) applies Value-at-Risk as risk measure and is ambiguous about the loss distribution. Our results show that: (1) under model uncertainty, ambiguity aversion results in a distorted probability distribution over the set of possible models with a bias in favor of the model which yields a larger risk; (2) a more ambiguity-averse DM would demand more insurance coverage; (3) for a given budget, uncertainties about the loss distribution result in higher risk level for the DM.
A diachronic analysis of the adjective intensifierwellfrom Early Modern English to Present Day English
Authors: Stratton James M. 
Published: May 2020

AbstractWhile the use ofwellas an intensifier of most adjectives had supposedly died out by Early Modern English (Fettig 1934: 186, Mustanoja 1960: 327, Stenström 2000: 188, Ito and Taglimonte 2003: 278), no studies have empirically examined its frequency diachronically. The present study traces its use from Early Modern English (1560) to Present Day English, (2014) using five speech-related corpora in addition to various dialectal sources and audio/video clips. Results indicate that this use was retained in some dialects of English despite not being attested in theCorpus of English Dialoguesnor theOld Bailey Corpus,which document predominantly the incipient standard variety. A qualitative analysis of its use reveals a potential diachronic shift in its stress pattern and the scale structure of its intensified heads. Moreover, the present study discusses some of the methodological challenges which arise when using historical corpora to investigate linguistic change, drawing particular attention to sample representativeness and data analysis.
WHO Paradoxes in Emergency Operations: The Dilemma of a UN Specialized Agency
Authors: Ali Maher Osama , Bellizzi Saverio 
Published: May 2020

ABSTRACTThe past two decades have witnessed a major shift in humanitarian operations to respond to more internal conflicts instead of the traditional cross-border wars. Over the recent years, two major shifts have taken place within the WHO to orient toward response to emergencies, namely the introduction of the Humanitarian Reform and the Cluster Approach in 2005 and the introduction of the Emergency Response Framework (ERF). The financing of the agency in humanitarian operations is adding emerging elements to the WHO operations, especially because of the constantly higher contribution from non-state- and state- funding agencies. Pending issues include aspects like health strategy, conflict analysis, legal issues of aid delivery, impartiality in delivering services, and other aspects and needs.
Cognition and communication: situational awareness and tie preservation in disrupted task environments
Authors: Fitzhugh Sean M. , Decostanza Arwen H. , Buchler Norbou , Ungvarsky Diane M. 
Published: May 2020

AbstractIndividuals filling specialized, interdependent organizational roles achieve coordinated task execution through effective communication channels. Such channels enable regular access to information, opportunities, and assistance that may enhance one’s understanding of the task environment. However, the time and effort devoted to maintaining those channels may detract from one’s duties by turning attention away from the task environment. Disrupted task environments increase information requirements, thus creating a dilemma in which individuals must sustain benefits offered by important communication channels and relieve burdens imposed by ineffective channels. Using separable temporal exponential random graph models (STERGMs), this paper examines the relationship between situational awareness (SA) and the propensity to sustain or dissolve preexisting communication channels during 10 disruptive events experienced sequentially by a large, multifaceted military organization during a 2-week training exercise. Results provide limited evidence that increased SA detracts from tie preservation; instead SA begins to predict tie preservation during the second week of the exercise. Patterns of organizational adaptation reveal that, over time, improvised coordinative roles increasingly fall upon those with elevated SA. These results suggest that over successive disruptions, the benefits of information provided by communication channels within interdependent, role-specialized organizations begin to outweigh the costs of sustaining those channels.
The conditional nature of publication bias: a meta-regression analysis
Authors: Owen Erica , Li Quan 
Published: May 2020

AbstractPublication bias is pervasive in social and behavioral sciences because journals and scholars tend to reward and be rewarded for statistically significant findings. However, the determinants of the severity of publication bias are less well understood. We argue that publication bias depends on whether an independent variable is a key variable or statistical control in traditional regression modeling. The bias should be severe only for the key variable that relates to a central question and hypothesis in a study. We offer an empirical strategy to detect the conditional nature of publication bias. As an illustration, we perform a meta-regression of 229 model estimates from 36 articles in the democracy-foreign direct investment literature. We find that publication bias is most severe when democracy is a key variable, but appears weak when democracy is a control. Our research demonstrates that empirical estimates for key and control variables follow different data generation processes and makes a novel contribution to the study of publication bias that affects many research areas.
Political alignment between firms and employees in the United States: evidence from a new dataset
Authors: Stuckatz Jan 
Published: May 2020

AbstractI present a novel measure of partisan alignment between firms and employees. This measure is constructed using data matching 1,691,790 US federal campaign contribution filings of 85,109 individuals to the donations of 874 Political Action Committees (PACs) of publicly listed US companies between 2003 and 2016. The alignment measure shows that employee and employer contributions are highly correlated. Furthermore, firm- and occupation-level factors are significantly associated with firm–employee alignment. Uniquely, these new data can be easily linked to external data on industries, firms, and occupations and consequently allow for in-depth analysis of precisely how companies can influence employees’ politics.
Conditional symmetries and exact solutions of a nonlinear three-component reaction-diffusion model
Authors: CHERNIHA R. M. , DAVYDOVYCH V. V. 
Published: May 2020

AbstractQ-conditional (non-classical) symmetries of the known three-component reaction-diffusion (RD) system [K. Aoki et al. Theor. Popul. Biol. 50, 1–17 (1996)] modelling interaction between farmers and hunter-gatherers are constructed for the first time. A wide variety of Q-conditional symmetries are found, and it is shown that these symmetries are not equivalent to the Lie symmetries. Some operators of Q-conditional (non-classical) symmetry are applied for finding exact solutions of the RD system in question. Properties of the exact solutions (in particular, their asymptotic behaviour) are identified and possible biological interpretation is discussed.
Toward a pattern-based referencing tool: Learner interactions and perceptions
Authors: Lai Shu-Li , Chang Jason S. 
Published: May 2020

AbstractIn this process-based study, we introduced a collocation tool with a new interface and advanced search features and examined how a class of EFL college students interacted with it. To elicit their tool consultation behaviors, a vocabulary test with collocation questions was designed. The students’ use of the tool to answer the vocabulary questions was screen-recorded for further analysis, serving as the major data source. One-on-one interviews with selected students were then conducted to clarify issues related to the study and their experience in using the tool. The findings indicated that the pattern-based tool was efficient in helping students solve collocation problems. This paper concludes with some pedagogical implications and suggestions for further research.

Published: May 2020

AbstractPain management for patients with chest trauma in aeromedical prehospital and retrieval medicine is important in order to maintain respiratory function. However, it can be challenging to achieve with opioids alone due to side effects including sedation, respiratory depression, and nausea.Reported are two trauma patients with uncontrolled pain despite multiple doses of opioids managed with a single-injection erector spinae plane block (ESB).The sono-anatomy and performance of the block, indications, and possible complications associated with the ESB are described.An ultrasound-guided ESB is useful for multimodal pain therapy following chest trauma in aeromedical retrieval medicine.
Fear, Institutionalized Racism, and Empathy: The Underlying Dimensions of Whites’ Racial Attitudes
Authors: DeSante Christopher D. , Smith Candis Watts 
Published: May 2020

ABSTRACTFor nearly 75 years, scholars of American public opinion have sought to measure whites’ attitudes toward blacks: social scientists have invented and revised ways to measure what we could refer to as “racial prejudice.” With each revision, scholars who believe they have captured new forms of racial animus are met with opposition from those who believe that old-fashioned anti-black affect is a thing of the past. We directly answer these claims by collecting a surfeit of attitudinal measures to simultaneously estimate the relationship between cognitive beliefs about the racial status quo and emotional reactions to racism. First, we uncover that two higher-order dimensions undergird whites’ racial attitudes. Second, we validate a four-item version of our new battery using the 2016 Cooperative Congressional Election Study.
“God loves the rich.” The Economic Policy of Ennahda: Liberalism in the Service of Social Solidarity
Authors: Ben Salem Maryam 
Published: May 2020

AbstractThe article examines the economic vision of the Tunisian Islamist party Ennahda focusing on its supposed transformation from a party with socialist rhetoric to one embracing fully the tenets of neo-liberalism. The article argues that such a transformation has been quite easy to achieve because the party and its leaders were always more pragmatic than ideological when it comes to economic policy-making. In fact, the party is more at ease with neo-liberal economics because of the electoral constituency it serves and because of its internal structure and ways of operating, which reward those members who display the virtues that the neo-liberal economy also values.
Geology of the Souter Head subvolcanic complex, Aberdeenshire, Scotland: an Ordovician granite-related Mo–(Bi–As–Au) system
Authors: RICE Clive M. , MARK Darren F. 
Published: May 2020

ABSTRACTAn Ordovician subvolcanic intrusive complex hosted by Neoproterozoic metasediments crops out at Souter Head about 6km S of Aberdeen, Scotland. The complex is composed mainly of two-mica red granite and breccia with minor dykes of pegmatite, quartz porphyry, felsite and dolerite, and widespread quartz veining, hydrothermal alteration and minor molybdenite mineralisation. Anomalous levels of bismuth (Bi), arsenic (As) and gold (Au) occur in quartz–pyrite veins. The complex has been mapped and the major- and minor-element geochemistry, including rare-earth elements of intrusives and mineralisation, has been determined. These data reveal a complex tectonic, intrusive and hydrothermal history. The intrusives are peraluminous and magnetite-, muscovite- and garnet-bearing. The youngest member, a quartz porphyry, is highly fractionated. There are two stages of hydrothermal activity: the first is linked to the explosive release of volatiles from a granite cupola and breccia formation; and the second, widespread quartz veining. Mo is associated with both stages, and Bi–As–Au anomalies are found in late quartz–pyrite veins. The mineralisation is classified as a granite-related vein-type Mo system. The unique preservation, in the Grampian terrane, of an Ordovician subvolcanic complex may be attributed to pre-Devonian movements on the nearby Dee fault and possibly also the collapse of the magma chamber following the explosive release of volatiles. The combination of large size, poor exposure and abundant multi-stage hydrothermal activity suggests that there is potential for further Mo and possibly Au mineralisation in this complex. Further mineralisation of this style may be present in the NE Grampian terrane.
Comment on “Sedimentation Controls on Methane‐Hydrate Dynamics Across Glacial/Interglacial Stages: An Example From International Ocean Discovery Program Site U1517, Hikurangi Margin” by E. J. Screaton et al.
Authors: Sultan Nabil 
Published: May 2020

AbstractIn the IODP 372A proposal, working hypotheses used with respect to actively deforming gas hydrate‐bearing landslides were based on an initial calculation considering gas hydrate to occur in fresh water. This initial inaccuracy leads to predict the base of methane hydrate stability zone (MHSZ) to be at around 162 m below the seafloor (mbsf) at site U1517 while it is expected to be between 85 and 128 mbsf. It is most interesting that important negative chloride anomalies were measured well below the theoretical MHSZ without direct evidence of the presence of gas hydrate. These anomalies are usually a strong indication of gas hydrate occurrence. This initial inaccurate hypothesis provides the opportunity to evaluate the effectiveness of the indirect salinity detection method to quantify gas hydrate.

AbstractThe presence of ~NS‐trending rifts within the Tibetan Plateau attests that it is undergoing ~EW extension. In southern Tibet, the total extension rate, distributed across seven main rifts over a distance of ~1,000 km, has been inferred to amount to about half of the shortening rate across the Himalayas. Quantifying the late Quaternary extension rates across the largest rift (Yadong‐Gulu rift [YGR]) is important to understand Tibetan deformation and to discuss the high plateau evolution during the later stages of continental collision. We performed10Be surface‐exposure cosmogenic nuclide dating of 57 samples from three fluvial surfaces and two moraines that are vertically offset by the normal faults bounding the northern YGR. After carefully assessing individual ages at each site, to elucidate scatter in the age distributions, we obtained ~EW extension rates of up to 3–6 mm/yr near the northern end of the rift (Gulu) and of only 1.3 ± 0.3 mm/yr in the south (Yangbajing). The fast rates in the north may be influenced by dextral slip along the Beng Co fault, whose rate ought to be at least 6.0 ± 1.8 mm/yr. The total late Quaternary extension rate of 9 ± 2 mm/yr we infer across southern Tibet between ~81°E and 92°E, assuming similar rates across each rift, is similar to earlier, qualitative inferences and consistent with recent geodetic results. Distinct deformation rates north and south of the Bangong‐Nujiang suture may reflect significant differences between the extensional kinematics and mechanisms across the Qiangtang and Lhasa blocks.

AbstractIn the atmosphere, microphysics refers to the microscale processes that affect cloud and precipitation particles and is a key linkage among the various components of Earth's atmospheric water and energy cycles. The representation of microphysical processes in models continues to pose a major challenge leading to uncertainty in numerical weather forecasts and climate simulations. In this paper, the problem of treating microphysics in models is divided into two parts: (i) how to represent the population of cloud and precipitation particles, given the impossibility of simulating all particles individually within a cloud, and (ii) uncertainties in the microphysical process rates owing to fundamental gaps in knowledge of cloud physics. The recently developed Lagrangian particle‐based method is advocated as a way to address several conceptual and practical challenges of representing particle populations using traditional bulk and bin microphysics parameterization schemes. For addressing critical gaps in cloud physics knowledge, sustained investment for observational advances from laboratory experiments, new probe development, and next‐generation instruments in space is needed. Greater emphasis on laboratory work, which has apparently declined over the past several decades relative to other areas of cloud physics research, is argued to be an essential ingredient for improving process‐level understanding. More systematic use of natural cloud and precipitation observations to constrain microphysics schemes is also advocated. Because it is generally difficult to quantify individual microphysical process rates from these observations directly, this presents an inverse problem that can be viewed from the standpoint of Bayesian statistics. Following this idea, a probabilistic framework is proposed that combines elements from statistical and physical modeling. Besides providing rigorous constraint of schemes, there is an added benefit of quantifying uncertainty systematically. Finally, a broader hierarchical approach is proposed to accelerate improvements in microphysics schemes, leveraging the advances described in this paper related to process modeling (using Lagrangian particle‐based schemes), laboratory experimentation, cloud and precipitation observations, and statistical methods.

Published: May 2020

AbstractA survey of intraseasonal, seasonal, and interannual precipitation and 850 hPa winds for various monsoon regimes around the world is presented for the Community Earth System Model Version 2 (CESM2) compared to observations and the previous generation CESM1. In CESM2 the south Asian monsoon has a reduction of excessive precipitation in the western Indian Ocean and an increase of precipitation in the eastern Bay of Bengal and land areas of Vietnam, Cambodia, and Laos. The seasonal timing of the south Asian monsoon, monsoon‐ENSO connections, and monsoon intraseasonal variability all are improved compared to CESM1. For the Australian monsoon, deficient precipitation over the Maritime Continent has been improved in CESM2 with increases of precipitation over the large tropical islands of Borneo, Celebes, and Papua New Guinea and decreases over southwestern Australia. In the West African monsoon, May–June seasonal rainfall occurs more preferentially over the African coast in CESM2 as in observations, and excessive rainfall over the Ethiopian region is reduced. During July–September in the West African monsoon, deficient precipitation over equatorial Africa in CESM1 has been lessened in CESM2, and there are increases in precipitation over the Guinean coast, though there is little overall improvement in the South African monsoon. In the South American monsoon, precipitation in CESM2 is improved with increased precipitation over the Amazon in central and western Brazil. CESM2 simulates a reduction of excessive precipitation seen in CESM1 over coastal Mexico extending up into the U.S. Great Plains in the North American monsoon.
A Method for Enhancing Capacity of Local Governance for Climate Change Adaptation

Published: May 2020

AbstractThe lack of capacity for climate change adaptation at the subnational level has been highlighted as a key barrier to implementing the UNFCCC National Adaptation Plans. At the same time, the adaptive capacity of local governance is highly context sensitive, making a “one‐size fits all” approach inappropriate. Thus, a versatile methodological approach for application in various local contexts is required. There are several indicator‐based local governance assessment methods for evaluating the effectiveness of local governance for climate change adaptation. However, they fall short of identifying and prioritizing between key factors within local governance for enhancing adaptive capacity and driving positive change. Building on adaptation theory, the authors propose combining two methodological approaches, the Capital Approach Framework for evaluating the adaptive capacity of local governance and Fuzzy Cognitive Mapping for identifying leverage points, into one integrated modeling approach, which can be applied by local researchers. This paper describes the process and benefits of combining the methodological approaches, with an example provided as supporting information. Assisting decision‐makers and policy planners from subnational governance in identifying leverage points to focus and maximize impact of capacity‐enhancing measures would make a key contribution for successful implementation of the UNFCCC National Adaptation Plans.

Published: May 2020

AbstractCircular RNAs (circRNAs), non-coding RNAs generated by precursor mRNA back-splicing of exons, have been reported to fulfill multiple roles in cancer. However, the role of quite a lot circRNAs in colorectal cancer (CRC) remains mostly unknown. Herein, we explored the expression profiles of circRNAs in 5 paired samples of CRC patients by microarray and noted a circRNA, hsa_circ_0005615 (circ5615), was significantly upregulated in CRC tissues. Circ5615 was derived from exon 2 of NFATC3 and its upregulation was tightly correlated with higher T stage and poor prognosis in CRC patients. Studies in vitro and in vivo demonstrated that knockdown of circ5615 in cancer cells inhibited proliferation and cell cycle acceleration, while overexpression promoted malignant phenotypes. Mechanistically, RNA immunoprecipitation, biotin-coupled probe pull-down and luciferase reporter assays revealed circ5615 effectively bound to miR-149-5p and might play a role like miR-149-5p sponge. Additionally, tankyrase (TNKS), regulator of β-catenin stabilization, was identified as circ5615 downstream and the potential miR-149-5p targets by RNA-seq and bioinformatics analysis. We further verified the upregulation of β-catenin and cyclin D1 induced by circ5615. Our results indicated that circ5615 exerted oncogenic function as competing endogenous RNA (ceRNA) of miR-149-5p to release TNKS and activated Wnt/β-catenin pathway.
