Evaluation of Problem-Based Learning in College of Medicine: An Indicator of Quality Education in a Hybrid Curriculum

Background. A culture of quality is believed to drive institutes toward excellence through feedback. Multiple surveys at educational institute help to get a deeper insight into institutional performance and curricular execution. Since problem-based learning (PBL) is an important component of the hybrid curriculum, thus stakeholders’ opinion on PBL satisfaction is worth discussing. This study intended to determine the trends in students’ satisfaction with PBL over the years and to report on the importance of curricular changes that can be incorporated based on students’ needs. Methods. This is a descriptive cross-sectional study that was conducted at the College of Medicine (COM), King Saud Bin Abdul Aziz University for Health Sciences (KSAU-HS), Jeddah, Saudi Arabia. All male and female medical students, using consecutive sampling technique, were included in the study. End-of-course evaluation reports for the academic years ranging from 2013 to 2019 on PBL satisfaction, with a response rate of ≥60%, were included in this study. Results. Overall, students at the COM, Jeddah were satisfied with PBL. A declining but satisfactory trend followed by a sharp rise in satisfaction was observed in this study. Pearson correlation reported a positive relationship between PBL problems, tutors, and PBL sessions (r = 0.82, p < 0.001 ). Conclusions. Transition from three sessions to two sessions per PBL case can be considered as an effective and efficient way of curricular execution. We found that the tutor, the case, and session dynamics were positively correlated after the incorporation of the feedback. Thus, highlighting the facts that inculcating a culture of responding to feedback can lead to innovations in medical teaching and can help to improve the curricular execution and students’ satisfaction.

Recovery of insular seabird populations years after rodent eradication.

Seabirds have been particularly affected by invasive non-native species, which has led to the implementation of numerous eradication campaigns for the conservation of these keystone and highly vulnerable species. Although the benefits of eradication of invasive non-native species for seabird conservation have been demonstrated, the recovery kinetics of different seabird populations on islands after eradication remains poorly evaluated. We conducted long-term monitoring of the number of breeding pairs of seven seabird species on a small atoll, Surprise Island, New Caledonia (southwestern tropical Pacific). Marine avifauna of the island were surveyed yearly 4 years before to 4 years after rodent eradication (conducted in 2005), and we conducted multiple one-time surveys from ∼10 years before and ∼15 years after eradication. We sought to determine how different seabird species responded to the eradication of invasive rodents in an insular environment. Three species responded positively (two- to 10-fold increase in population size) to eradication with differences in lag time and sensitivity. The number of breeding pairs increased (effect sizes = 0.49-0.95 and 0.35-0.52) for two species over 4 years post-eradication due to immigration. One species had a longer (at least 5 years) response time than all others; breeding pairs increased for over 10 years after eradication. Long-term sampling was necessary to observe the responses of the seabird populations on the island because of the delayed response of a species to eradication not visible in the first years after eradication. Our results confirmed the positive effects of eradication of invasive non-native species on seabirds and emphasize the importance of mid- and long-term pre- and posteradication surveys to decipher the mechanisms of seabird recovery and confirm the benefits of eradication for conservation purposes.

The impact of political ideology, knowledge and participation on electoral conspiracy endorsement

From voting fraud to Russian interference, electoral conspiracy theories have circulated on social media since the 2016 United States presidential election with alarming magnitude. Previous conspiracy studies have primarily focused on psychological causes that contribute to the conspiracy mentality, and the discussion on political antecedents of conspiracy endorsement remains lacking. This study selects popular conspiracies reflecting various political ideologies and conducts multiple survey rounds (n = 500) to compare and contrast the effect of partisan affiliations on conspiracy endorsement. Drawing from the extant literature from psychology, communication, and political science and using two-way and three-way interaction models, this study examines three political antecedents—political ideology, knowledge, and participation—and their interactive effects on conspiracy endorsement. The results indicate that individuals with higher levels of political affiliation and knowledge illustrate stronger conspiracy endorsement, and this effect is stronger for conservatives than liberals. Additionally, increased political participation reduces the endorsement of conservative conspiracies and heightens the endorsement of liberal ones among both conservatives and liberals.

Effectiveness of Screening Using Fecal Occult Blood Testing and Colonoscopy on the Risk of Colorectal Cancer: The Japan Public Health Center-based Prospective Study.

Few cohort studies have used multiple surveys of screening attendance to simultaneously evaluate the effectiveness of fecal occult blood test (FOBT) and colonoscopy. We analyzed data of 30,381 middle-aged Japanese adults from a population-based prospective cohort study. Information on FOBT and colonoscopy was obtained from three questionnaire surveys (every 5 years). We classified the subjects into three groups: the FOBT (15,649 subjects), screening colonoscopy (2,407 subjects), and unscreened (12,325 subjects) groups. We used the unscreened group as the reference group to compare the mortality and incidence of colorectal cancer (CRC). During the 14-year follow-up, 64, 12, and 104 CRC deaths were identified in the FOBT, screening colonoscopy, and unscreened groups, respectively. The risk of CRC death reduced with increasing the number of FOBTs (P for trend = 0.02) and was reduced by 44% in the subjects screened twice or thrice using FOBT (hazard ratio [HR] 0.56; 95% confidence interval [CI], 0.33-0.94). Significant decreases were seen for the incidence of CRC but not seen for the incidence of non-advanced CRC in the FOBT group. Concerning the screening colonoscopy, subjects screened at the start of follow-up showed a 69% reduced risk of CRC death (HR 0.31; 95% CI, 0.10-0.9996). Significant decreases were also seen for the incidence of CRC and non-advanced CRC in the subjects screened at the start of follow-up. FOBT, depending on the number of FOBTs, and colonoscopy, depending on recency, reduced the risk of death due to CRC and the incidence of CRC.

Ideology and Support for Federalism in Theory—And in Practice

Abstract Conservatives are more likely than liberals to support the concept of federalism. In this article, we look at this support in the context of particular issues. Using multiple national surveys, including an original module on the 2020 Congressional Election Study, we find that conservatives are more likely to prefer a devolution of power to state and local jurisdictions, even if doing so might make it harder to achieve conservative policy aims, whereas liberals are more instrumental, more likely to prioritize policy aims and to support whichever level of government seems most likely to achieve them. We then examine reasons why conservatives might display a stronger adherence to the federalist structure of the American government. We find that the idea of “states’ rights” continues to loom large for self-identified conservatives, as does a generalized level of trust toward political units described as small versus large.

Optimizing Surveys for Imperiled Bat Species Post White-Nose Syndrome

Many bat populations have plummeted in North America since the introduction of white-nose syndrome (WNS) in 2006, presenting challenges in researching population health and habitat use of affected species. Traditional survey techniques such as mist-netting and radio-telemetry have become increasingly time-consuming post-WNS due to the rarity of WNS-susceptible species in affected areas. To address the difficulty of studying imperiled bat species, we explored the use of an acoustic lure alongside mist-netting and acoustic monitoring to potentially enhance species detection in southeastern Missouri, United States. Acoustic lures elicit varying intra- and interspecific behavioral responses; thus, we explored the effects on multiple bat species' encounter rates while using tricolored bat Perimyotis subflavus distress vocalizations. The acoustic lure increased the number of acoustic detections for the federally endangered Indiana bat Myotis sodalis and non-imperiled big brown bat Eptesicus fuscus, and increased captures of the silver-haired bat Lasionycteris noctivagans, a species of conservation concern in Missouri. Additionally, only two individuals of P. subflavus were captured in mist-nets, and both were captured with the acoustic lure. These results suggested that acoustic lures are a valuable tool for identifying the presence of imperiled species when used in combination with mist-netting and acoustic detectors. Researchers studying bat communities that have experienced significant population declines because of WNS or other factors should incorporate multiple survey techniques, including acoustic lures, to increase capture rates and better document species distributions. Doing so should provide more accurate information on the distribution of imperiled bat species, which is relevant to conservation and management.

The Role of Fishery‐Independent Bottom Trawl Surveys in Providing Regional and Temporal Context to Offshore Wind Farm Monitoring Studies

AbstractBottom trawl surveys are commonly used to examine potential effects on fishes and invertebrates from offshore wind (OSW) farms in Europe and in the northeastern United States. Because OSW surveys typically occur over a limited spatial footprint, comparison of OSW monitoring results to long‐term fishery‐independent surveys may provide a regional and temporal context for OSW data sets. We compared results of the Block Island Wind Farm (BIWF) bottom trawl survey (2013–2019) to three fishery‐independent bottom trawl surveys (Northeast Area Monitoring and Assessment Program, Northeast Fisheries Science Center, and Rhode Island Department of Environmental Management [RIDEM]) using catch rates of 12 federally managed species. We evaluated temporal trends in annual residual catches for each species calculated within each survey as the difference between the mean annual biomass per trawl and the long‐term mean. Regional consistency in relative catches was apparent for species exhibiting synchronous interannual variability among surveys (Black Sea Bass Centropristis striata, Scup Stenotomus chrysops, Summer Flounder Paralichthys dentatus, and Winter Flounder Pseudopleuronectes americanus) or a decreasing trend in residual catch rates across the 7‐year study period (Little Skate Leucoraja erinacea, longfin inshore squid Doryteuthis pealeii, and Winter Skate L. ocellata). For other species, catches among surveys were asynchronous (Atlantic Herring Clupea harengus, Butterfish Peprilus triacanthus, and Windowpane Scophthalmus aquosus) or anomalous catches in a single year affected the results (Red Hake Urophycis chuss and Silver Hake Merluccius bilinearis). Monitoring of BIWF occurred during a period with lower‐than‐average historical catches in a 32‐year RIDEM data set for Atlantic Herring, Butterfish, Little Skate, longfin inshore squid, Red Hake, Silver Hake, and Winter Flounder and higher‐than‐average catches for Black Sea Bass, Scup, and Summer Flounder. There was no evidence that variation in catches near BIWF differed from regional trends in a way consistent with a detrimental impact of OSW farm operation. The regional context provided from multiple bottom trawl surveys varies by species and thus may be limited for interpreting OSW monitoring results.

Our Checkered Past

ABSTRACTDespite advocacy of landscape approaches in cultural resource management (CRM) and critiques of the site concept, CRM data collection methods in the western United States continue to focus on individual archaeological sites as units of observation, analysis, and management. The transect-recording unit (TRU) method strikes a balance between conventional site-based recording methods and site-less survey approaches by dividing survey space into a grid of uniformly sized cells for recording all cultural manifestations observed across a survey area. TRU survey generates site boundaries required by CRM regulations while retaining a fine-grained spatial framework for landscape-level research and management. This article discusses the technical requirements of the TRU system and its potential for improving landscape-level research and management. Advances in digital recording technologies and analysis techniques render the method efficient and effective in identifying cultural resource distributions and characteristics otherwise obscured by conventional approaches. The research and management potential of the TRU system is illustrated through identification and interpretation of precontact foot trails in New Mexico's Tularosa Basin. These trails are essentially invisible during pedestrian survey but are readily identifiable as linear patterns using aggregated landscape-scale TRU survey data from multiple survey projects, providing novel insight into precontact routes of movement and exchange.

Kepler K2Campaign 9 – II. First space-based discovery of an exoplanet using microlensing

ABSTRACTWe present K2-2016-BLG-0005Lb, a densely sampled, planetary binary caustic-crossing microlensing event found from a blind search of data gathered from Campaign 9 of the Kepler K2 mission (K2C9). K2-2016-BLG-0005Lb is the first bound microlensing exoplanet discovered from space-based data. The event has caustic entry and exit points that are resolved in the K2C9 data, enabling the lens-source relative proper motion to be measured. We have fitted a binary microlens model to the Kepler data and to simultaneous observations from multiple ground-based surveys. Whilst the ground-based data only sparsely sample the binary caustic, they provide a clear detection of parallax that allows us to break completely the microlensing mass-position-velocity degeneracy and measure the planet’s mass directly. We find a host mass of 0.58 ± 0.04 M⊙ and a planetary mass of 1.1 ± 0.1 MJ. The system lies at a distance of 5.2 ± 0.2 kpc from Earth towards the Galactic bulge, more than twice the distance of the previous most distant planet found by Kepler. The sky-projected separation of the planet from its host is found to be 4.2 ± 0.3 au which, for circular orbits, deprojects to a host separation $a = 4.4^{+1.9}_{-0.4}$ au and orbital period $P = 13^{+9}_{-2}$ yr. This makes K2-2016-BLG-0005Lb a close Jupiter analogue orbiting a low-mass host star. According to current planet formation models, this system is very close to the host mass threshold below which Jupiters are not expected to form. Upcoming space-based exoplanet microlensing surveys by NASA’s Nancy Grace Roman Space Telescope and, possibly, ESA’s Euclid mission, will provide demanding tests of current planet formation models.

Women in Montenegro exhibit a high degree of happiness and life satisfaction: Data from the Multiple Independent Cluster Survey 2018

Aim: Montenegrin government is increasingly aware of the key role of women in the society and attempts to improve social cohesion among Montenegrin people. Precondition is a high degree of life satisfaction and happiness. Methods: We used the Multiple Indicator Cluster Survey (MICS) of 2018 to analyse the distribution and interaction of 22 potential determinants out of 383 variables available. The participation rate was 77.7 or 2,276 women aged 15-49 years out of 2,928 invited. As data quality turned out to be limited, we employed a data mining approach, i.e. an interactive Classification and Regression Tree (C&RT). Happiness was measured ranging from very happy to very unhappy on a categorical scale of 5 steps Results: Of all Montenegrin women 70.7% declared themselves as very happy. Likewise, a 10-point scale of life satisfaction classifies 82.0% of the sample in the top ranks 8-10. Furthermore, 73.6% of the women expect the next year to be even better. Wealth, younger age, and marriage or living in union determine the status of happiness. Conclusion: Women in Montenegro exhibit a high degree of self-reported happiness and life satisfaction. Montenegrin policies should continue to support the role of women in the society.

Regional and country-level trends in cervical cancer screening coverage in sub-Saharan Africa: A systematic analysis of population-based surveys (2000-2020).

Sub-Saharan Africa (SSA) has the highest cervical cancer (CC) burden globally-worsened by its HIV epidemics. In 2020, the World Health Organization (WHO) introduced a CC elimination strategy with goals for vaccination, screening, and treatment. To benchmark progress, we examined temporal trends in screening coverage, percent screened at least twice by the age of 45, screening coverage among women living with HIV (WLHIV), and pre-cancer treatment coverage in SSA. We conducted a systematic analysis of cross-sectional population-based surveys. It included 52 surveys from 28 countries (2000 to 2020) with information on CC screening among women aged 25 to 49 years (N = 151,338 women). We estimated lifetime and past 3-year screening coverage by age, year, country, and HIV serostatus using a Bayesian multilevel model. Post-stratification and imputations were done to obtain aggregate national, regional, and SSA-level estimates. To measure re-screening by age 45, a life table model was developed. Finally, self-reported pre-cancer treatment coverage was pooled across surveys using a Bayesian meta-analysis. Overall, an estimated 14% (95% credible intervals [95% CrI]: 11% to 21%) of women aged 30 to 49 years had ever been screened for CC in 2020, with important regional and country-level differences. In Eastern and Western/Central Africa, regional screening coverages remained constant from 2000 to 2020 and WLHIV had greater odds of being screened compared to women without HIV. In Southern Africa, however, screening coverages increased and WLHIV had equal odds of screening. Notably this region was found to have higher screening coverage in comparison to other African regions. Rescreening rates were high among women who have already been screened; however, it was estimated that only 12% (95% CrI: 10% to 18%) of women had been screened twice or more by age 45 in 2020. Finally, treatment coverage among 4 countries with data was 84% (95% CrI: 70% to 95%). Limitations of our analyses include the paucity of data on screening modality and the few countries that had multiple surveys. Overall, CC screening coverage remains sub-optimal and did not improve much over the last 2 decades, outside of Southern Africa. Action is needed to increase screening coverage if CC elimination is to be achieved.

Geological and geotechnical characterisation of soft Holocene marine sediments: A case study from the north Irish Sea

The seabed of the Western Irish Sea Mud Belt (north Irish Sea) comprises a thick sequence of fine-grained Holocene marine sediments that overlay complex glacial deposits. The Holocene sequence preserves a record of environmental change in the area. Part of this area is earmarked for a number of offshore wind farm developments. The area poses a number of geotechnical challenges to such developments, including soft marine silts and clays as well as shallow gas. This paper characterises the soil conditions in the area in the context of offshore renewable energy development using various geophysical techniques, geotechnical data and shallow (3 m) sediment samples obtained across multiple research surveys between 2009 and 2020. The purpose is to assess the use of such techniques, including multichannel sparker seismic and underwater multichannel analysis of surface waves (UMASW), in characterising these kinds of sediments. It is also intended to build on previous research and provide a reference dataset and case study for further work in developing offshore wind in the area. UMASW and in-situ cone penetration testing with pore pressure measurement (CPTu) results showed good agreement in characterising these Holocene sediments, with multichannel sparker delineating shallow gas from surrounding sediments. Core profiles show distinct lithological variation in the upper 3 m, which can be related to CPTu parameters, but is not resolvable by UMASW profiles. Paleoenvironmental reconstruction for this upper 3 m suggests changes in depositional setting over the past ca. 7000 years, which could influence sedimentary structure. These parameters have implications for cable installation design.

Trends in the area of suitable breeding habitat for the Endangered Lake Titicaca Grebe Rollandia microptera, 2001–2020

Summary The Lake Titicaca Grebe Rollandia microptera is a poorly studied endemic species found in the Lake Titicaca watershed of Peru and Bolivia. Multiple surveys from the early 2000s indicated that the species was suffering a rapid population decline with an unknown cause. At the same time as these surveys, reports emerged that there was an increase in burning of the totora wetlands which are thought to be the primary habitat for the Lake Titicaca Grebe. However, since 2003, no work has been published either on the current population of the Lake Titicaca Grebe, or the extent of the totora wetlands in the Lake Titicaca region. This paper used satellite data to monitor the change in extent of habitat potentially suitable for the Lake Titicaca Grebe to determine whether habitat loss is likely to be a major driver of population declines in this species. We found that the extent of potentially suitable wetland remained stable between 2001 and 2020, though there are more local regional trends of change in extent of totora. We also found that multiple areas exist that might support Lake Titicaca Grebe populations, but where ornithological knowledge is lacking. We suggest no change to the IUCN status of the Lake Titicaca Grebe, but recommend that further fieldwork is required to monitor the species’ current population, especially in previously unstudied but potentially habitable areas.

Cervical Cancer in SAARC Countries.

Purvish M. ParikhIn the year 2020, a total of 342 000 women were estimated to die of cervical cancer, of which 90%) were expected amongst low- and middle-income countries (LMIC). Globally incidence of cervical cancer has reduced as a result of improved personal hygiene, better living conditions and higher application of opportunistic screening programs. Yet GLOBOCAN shows that absolute number of cases are still increasing. We therefore conducted a 21 question multiple choice questionnaire online survey in Jan 2023 amongst 9 SAARC countries. A total of 367 replies were received and the representative answers for each country are being reported in this manuscript. A good possibility of achieving World Health Assembly target (Nov 17, 2020) was felt only by Bhutan and Nepal. For screening, most countries (Bhutan, India, Myanmar, Nepal, Pakistan and Sri Lanka) recommend for all asymptomatic eligible patients. Public health experts have suggested VIA / VILI as the best solution for LMICs. However, a dual screening strategy (HPV DNA plus) cytology was preferred by doctors in Afghanistan, Bhutan, India, Myanmar, Pakistan and Sri Lanka. Screening, triage and then treatment was the preferred by Bangladesh, Bhutan, India, Maldives, Nepal, Pakistan, Sri Lanka. HPV vaccination was recommended in all girls between ages 10 to 26 years in Bangladesh, India, Myanmar, Nepal, Pakistan and Sri Lanka. All the 9 countries would use HPV vaccination to all eligible patients if the cost of the vaccine was reasonably low. Our survey clearly outlines challenges faced in tackling cervical cancer in SAARC countries. We also provide consensus regarding several potential solutions that can be used in both public and private cervical cancer control programs.

Population dynamics of chital deer (Axis axis) in northern Queensland: effects of drought and culling

Context Chital deer (Axis axis) are long established in the northern Queensland dry tropics, and at high densities are considered pests by cattle graziers. Cost-effective management is difficult for widespread, fluctuating populations of vertebrate pests such as these deer. Historically, control of chital deer has been limited to recreational and some commercial ground-shooting and trapping. Concerns over chital deer impacts were heightened during drought in 2015 and funding became available for aerial culling. Aim This study set out to determine (1) distribution and abundance, (2) seasonal reproductive output, (3) potential and actual rates of increase and their determinants, and (4) efficient management strategies for chital deer in the northern Queensland dry tropics. Methods In 2014, ~13 000 km2 of the main distribution was surveyed by helicopter. Multiple vehicle ground surveys per year monitored chital deer density on two properties during 2013–2022. Seasonal shot samples of deer on both properties assessed reproductive output during 2014–2016. Aerial surveys during 2016–2020 determined chital deer densities on seven properties, prior to aerial culling on four properties. Finally, the maximum rate of increase of chital deer was calculated from life-history data. Key results Regionally, chital deer are patchily distributed and so are best monitored locally where densities can be >50 deer km−2. Vehicle ground surveys recorded an ~80% decline in chital deer populations on two properties over 7–10 months during drought in early 2015, with a similar rate being recorded by aerial survey at a third site. There was little recruitment during the drought, but the decline was seemingly driven by adult mortality. Aerial shooting further reduced populations by 39–88% to <3 deer km−2 on four properties. Where there was no continuing control, culled populations recovered to pre-cull densities or higher after 2.4 years. One unculled property recovered to its pre-drought density after 6 years. Rates of recovery were at or higher than the maximum annual rate of increase for chital deer estimated here as 26–41%. Conclusions Drought has a lasting effect on this chital deer population, because of the resulting large population decline and the modest rate of any recovery in the absence of culling. Culling can reduce populations to low density, but the removal rate needs to be sustained to suppress future growth. Implications Drought provides a strategic opportunity to further reduce chital deer populations for enduring control. Large reductions are feasible given the clumped dispersion of populations within properties and in the region.

Burnout among European IBD specialists: a survey supported by ECCO

Background: Burnout remains a significant health concern within the healthcare sector. Numerous studies have explored burnout among gastroenterologists. However, as far as we are aware, there is currently no documented research specifically focused on burnout for specialists in the field of inflammatory bowel disease (IBD). Objective: The aim of our study was to assess the extent of burnout, its determinants, and to analyze potential risk factors among European healthcare professionals who provide care to patients with IBD. Methods: We carried out a cross-sectional pilot study involving healthcare professionals responsible for the treatment of patients with IBD. A total of 102 participants (56.9% male, average age 48 ± 10.6) completed the anonymous multiple question open web survey. The survey consisted of four distinct psychological constructs (burnout, depression, somatization, and well-being), along with inquiries associated with sociodemographic, health-related, and work-related factors. Results: In our study, we observed that 47.1% of professionals specializing in IBD experienced burnout. When considering all three factors of burnout simultaneously, 5.9% of participants fell within the moderate range. Among these, depersonalization (DP) was the most prevalent factor, with 48% at a medium level and 47.1% at a high level. Depression, somatization, and well-being correlated with emotional exhaustion (EE) and DP, while only depression correlated with personal accomplishment (PA). Furthermore, age, physical activity, total time spent in healthcare, and time spent as an IBD specialist were correlated with EE. Multiple linear regression analysis revealed that depression was the most dominant predictor of both PA and DP. In terms of work-related factors, we observed that having endoscopic access had a detrimental impact on burnout, while the presence of a dedicated IBD outpatient unit and opportunities to participate in multidisciplinary meetings had a positive effect on mitigating burnout. Conclusions: Our pilot study underscores the importance of burnout among IBD professionals in Europe, with a specific emphasis on DP. Subsequent studies may help to uncover the way underlying factors contribute to burnout, potentially laying the foundation for international support and prevention initiative programs.

Adopting a palliative care mindset is an unmet need in Parkinson’s disease

IntroductionParkinson’s disease (PD) affects multiple facets of patients’ lives, many of which may not be recognized or addressed by their healthcare team. A growing body of evidence has shown that palliative care improves patients’ quality of life with PD; however, little is currently known about how patients with PD perceive palliative care. MethodsAn 8-question multiple choice survey was created and given to patients with established care for PD at a movement disorders clinic in a quaternary care center. Patients with less than two years of follow-up or that had atypical features of PD were excluded from the survey. ResultsThere were 106 respondents to the survey. A third of patients reported having never heard of palliative care and an additional 25% had heard of it but did not know what it was. Eighty-eight percent reported being familiar with or very knowledgeable about hospice, though 50% of respondents did not know the difference between hospice and palliative care. 93% had never been offered either service. 37.7% thought their neurologist should discuss advance care planning early in the course of their disease. ConclusionEven among established patients with Parkinson’s disease in a quaternary center, over half were not familiar with palliative care, and the majority had never been offered palliative or hospice services despite growing evidence that it could improve their quality of life. Additionally, patients would like to be introduced to advanced care planning early in the course of their disease.

Error Aversions and Due Process

William Blackstone famously expressed the view that convicting the innocent constitutes a much more serious error than acquitting the guilty. This view is the cornerstone of due process protections for those accused of crimes, giving rise to the presumption of innocence and the high burden of proof required for criminal convictions. While most legal elites share Blackstone’s view, the citizen jurors tasked with making due process protections a reality do not share the law’s preference for false acquittals over false convictions. Across multiple national surveys sampling more than 12,000 people, we find that a majority of Americans consider false acquittals and false convictions to be errors of equal magnitude. Contrary to Blackstone, most people are unwilling to err on the side of letting the guilty go free to avoid convicting the innocent. Indeed, a sizeable minority view false acquittals as worse than false convictions; this group is willing to convict multiple innocent persons to avoid letting one guilty person go free. These value differences translate into behavioral differences: we show in multiple studies that jury-eligible adults who reject Blackstone’s view are more accepting of prosecution evidence and are more conviction-prone than the minority of potential jurors who agree with Blackstone. These findings have important implications for our understanding of due process and criminal justice policy. Due process currently depends on jurors faithfully following instructions on the burden of proof, but many jurors are not inclined to hold the state to its high burden. Courts should do away with the fiction that the reasonable doubt standard guarantees due process and consider protections that do not depend on jurors honoring the law’s preference for false acquittals, such as more stringent pretrial screening of criminal cases and stricter limits on prosecution evidence. Further, the fact that many people place crime control on par with, or above, the need to avoid wrongful convictions helps explain divisions in public opinion on important policy questions like bail and sentencing reform. Criminal justice proposals that emphasize deontic concerns without addressing consequentialist concerns are unlikely to garner widespread support.

MDA GAN: Adversarial-Learning-Based 3-D Seismic Data Interpolation and Reconstruction for Complex Missing

The interpolation and reconstruction of missing traces is a crucial step in seismic data processing, moreover it is also a highly ill-posed problem, especially for complex cases such as high-ratio random discrete missing, continuous missing and missing in fault-rich or salt body surveys. These complex cases are rarely mentioned in current works. To cope with complex missing cases, we propose Multi-Dimensional Adversarial GAN (MDA GAN), a novel 3-D GAN framework. It keeps anisotropy and spatial continuity of the data after 3D complex missing reconstruction using three discriminators. The feature splicing module is designed and embedded in the generator to retain more information of the input data. The Tanh cross entropy (TCE) loss is derived, which provides the generator with the optimal reconstruction gradient to make the generated data smoother and continuous. We experimentally verified the effectiveness of the individual components of the study and then tested the method on multiple publicly available data. The method achieves reasonable reconstructions for up to 95% of random discrete missing and 100 traces of continuous missing. In fault and salt body enriched surveys, MDA GAN still yields promising results for complex cases. Experimentally it has been demonstrated that our method achieves better performance than other methods in both simple and complex cases. Moreover, our network does not require training weights for each survey, the same weights it uses are applied to multiple surveys, significantly reducing time and computational costs, and we make the model publicly available on https://github.com/douyimin/MDA_GAN.
