Linking ecosystem services and circuit theory to identify priority conservation and restoration areas from an ecological network perspective

The Yellow River basin has been experiencing ecosystem fragmentation, conversion, and degradation. The ecological security pattern (ESP) can provide a systematic and holistic perspective for specific action planning to maintain ecosystem structural, functional stability, and its connectivity. Thus, this study focused on Sanmenxia, one of the most representative cities of the Yellow River basin, to construct an integrated ESP to provide evidence-based support for ecological conservation and restoration. We adopted four main steps, including measuring the importance of multiple ecosystem services, identifying ecological sources, constructing the ecological resistance surface, and linking the MCR model and circuit theory to identify the optimal path, optimal width, and key nodes of ecological corridors. Overall, we identified various ecological conservation and restoration priority areas in Sanmenxia, including 3593.08 km2 of ecosystem service hotspots, 28 corridors, 105 pinch points, and 73 barriers, and we highlighted multiple priority actions. This study provides an effective starting point for the future identification of ecological priorities at the regional or river basin scale.

Perceptual difference of smile aesthetics between 2-dimensional photographs and 3-dimensional dentofacial images: a cross-sectional study

BackgroundThe aim of this study was to compare the perceptual difference of smile aesthetics between 2D photographs and 3D dentofacial images as perceived by orthodontists and graduate students.MethodsForty-eight subjects finished orthodontic treatment were recruited with 2D photographs of frontal, oblique and lateral views as well as 3D dentofacial images. Twelve senior orthodontists and 13 postgraduate students were asked to rate the 2D and 3D smile simulations based on visual analog scale (VAS) and to vote for smile features that affect the attractiveness of smile. At the end, they completed a questionnaire about their views on different smile simulations. Wilcoxon signed-rank, Bland–Altman analysis, and multiple linear regression were used to compare the ratings and votes of smile perception between raters and between records.ResultsOrthodontists and postgraduate students rated smile consistently with 2D photographs, while orthodontists tended to give a higher rate for unattractive smiles and a lower rate for attractive smiles with 3D dentofacial images. The 3D dentofacial images were rated significantly lower than 2D photographs and the voting of most of the smile features showed significant negative main effect on VAS scores, while the effect of demographic characteristics of raters, voting on visible width of upper dentition and buccal corridor was not significant. In addition, a significant negative main effect of commissure and facial profile was found on the rating discrepancy between 2D and 3D images.ConclusionsSenior orthodontists tend to perceived 3D images more conservatively in smile evaluation. 3D dentofacial images were rated lower than 2D photographs and most of the smile features affect the aesthetic perception of smile. The perceptual difference of commissure and facial profile contributed to the lower ratings in 3D dentofacial images.

Atmospheric Density Estimation Techniques for Aerocapture

Aerocapture is a promising orbit insertion strategy that can reduce propellant mass requirements for planetary orbiters. Reliable aerocapture requires active guidance, navigation, and control systems for robust performance. Such systems rely on accurate models of the downstream density environment for accurate targeting capabilities. Two density profile prediction techniques are introduced that use density histories computed from navigation measurements to improve aerocapture targeting accuracy: the density interpolator and the ensemble correlation filter. The density interpolator stores density data on the descent portion of the vehicle’s trajectory, interpolating density values from this array during guidance predictions; whereas the ensemble correlation filter attempts to match density history data to onboard density profiles. A hybrid of the two methods is also considered. Both Earth and Venus are considered as planetary targets. A discrete-event control aerocapture scenario is considered, using Monte Carlo methods to assess the proposed methods’ performances and demonstrate improvement in both the apoapsis error and entry corridor width. Density interpolator strategies were shown to perform consistently better than the density scale factor approaches. Ensemble correlation strategies were shown to provide a larger performance benefit potential as compared to interpolator strategies, particularly in cases where density model confidence is high. However, density interpolator strategies were shown to improve performance over a wider range of Monte Carlo simulation conditions.

Perception of smile attractiveness among laypeople and orthodontists regarding the buccal corridor space, as it is defined by the eyes. An innovated technique.

To investigate whether there is a relationship between the distance between the iris and pupil with the ideal size of buccal corridors. A full-portrait image of a male Caucasian was used to create a set of 11 digitally modified images with different buccal corridor space. A web-based cross-sectional study was designed and distributed via an online survey to 200 laypeople and 200 orthodontists to assess image attractiveness, using a Visual analogue scale. For the statistical analysis, Wilcoxon signed-rank and Mann-Whitney U tests were used. The significance level was set at p < 0.05. The response rate for laypeople was 70% (n=139), while the rate for orthodontists was 73% (n=146). For the layperson group, the maximum smile attractiveness score was 10% of buccal width reduction, compared to the iris-pupillary distance, while for the orthodontists, it was 20%. The attractiveness of the smile was significantly reduced in both groups when the buccal corridor width was increased in comparison to the iris-pupillary distance. The length between the mesial part of the iris and the distal of the pupil, may constitutes a landmark for the estimation of the desired width of the buccal corridor. Inter iris-pupillary distance can be the starting point in the smile designing process, in order to perform a facial driven selection of buccal corridor size.

Is percutaneous fixation of the superior pubic ramus possible in all types of pelvis?

The impact of pelvis type on percutaneous fixation of the superior pubic ramus was investigated in this study. One hundred fifty pelvic CTs (female/male: 75/75) without anatomical changes in the pelvis were studied. Pelvis CT examinations with 1mm section width, pelvis typing, anterior obturator oblique, and inlet section images were created using the MPR and 3D imaging mode of the imaging system. In these images, whether a linear corridor could be obtained for the superior pubic ramus, corridor width, length, and angle values in the transverse and sagittal planes were measured in pelvic CT where linear corridor could be obtained. In 11 samples (7.3 %) (group 1), no linear corridor for the superior pubic ramus could be obtained in any way. All pelvis types in this group were gynecoid, and all belonged to female patients. A linear corridor in the superior pubic ramus could be easily obtained in all pelvic CTs with Android pelvic type. The superior pubic ramus was 8.2±1.8 mm in width and 116.7±12.8 mm in length. The corridor width was measured below 5 mm in 20 (13.3%) pelvic CT images (group 2). Corridor width showed a statistically signif-icant difference depending on the pelvic type and gender. The pelvic type is a determinat factor for the fixation of the percutaneous superior pubic ramus. For this reason, pelvic typing using MPR and 3D imaging mode in preoperative CT examination; is effective in surgical planning, implant, and surgical position selection.

Redesign of Four-leg Urban Intersection with Light Rail in a Street Corridor: Case Study in Zagreb

In the Croatian capital, Zagreb, there is a constant need for reconstruction of existing road infrastructure or construction of new infrastructure in accordance with current regulations and requirements due to its spatial expansion and increasing number of inhabitants and cars. The lack of uniform national guidelines and the insufficient width of corridors for the design of urban streets and intersections often lead to different and inconsistent solutions. Poorly constructed or reconstructed intersections in urban areas are becoming an increasing problem in the street network. Large cities have a complex traffic system due to the high traffic volume and different road users, so great attention should be paid to the geometric design of intersections. In this work, the existing intersection of Grad Vukovar and Donje Svetice streets in the city of Zagreb with a light rail corridor was analyzed, and two preliminary design variants for the reconstruction of the intersection were proposed to show the design problems and their solution.

Comparison of Buccal Corridor Width in Post Treatment Patients Treated with Non Extraction Vs Extraction Therapy in Mithilanchal Population

Introduction: A wide variety of opinion exists on the effect of extraction on the buccal corridor width which has a direct impact on smile esthetics. Till date no study regarding this has been done in Mithilanchal population. Aims and objectives: To compare the post-treatment buccal corridor width and posterior corridor width of patients treated with or without four first premolars extraction in Mithilanchal population. Materials and Methods: This was a cross-sectional study conducted at department of orthodontics and dentofacial orthopedics in Mithila Minority Dental College and Hospital, Darbhanga, Bihar. Post treatment posed smile photographs of 24 extraction patients and 24 non-extraction patients were compared using standardization and cropping in adobe Photoshop version 7.0. Statistical analysis was done with SPSS software (IBM Corp 2013; Version 22.0; Armonk, NY) and independent t-test to compare buccal corridor width and posterior corridor width between two groups. Results: The age group of subjects varied from 1 3 to 26 years. The mean age of group 1 (extraction) and group 2 (non-extraction) patients were 1 7.75 ± 4.48 years and 20.21 ± 4.03 years respectively. The mean width of buccal corridor in extraction patients were 35.33 ± 1 .52 % and for non-extraction group was found to be 35.38 ± 1 .54 %. (non-significant,p = 0.903). The posterior corridor mean width was 20.46 % in group 1 patients and 19.83% in group 2 patients (non-significant, p = 0.274). Conclusion: No significant difference in the buccal corridor and posterior corridor widths was found after orthodontic treatment with and without extraction of the first four premolars.

Evaluation of Buccal Corridors in Patients Seeking Orthodontic Treatment in Different Types of Malocclusion at Tertiary Care Hospital

There are many factors that make an appealing smile, and the buccal corridor is one of the most crucial smiling characteristics. Objective: To evaluate the width of buccal corridors in patients with different types of malocclusions seeking orthodontic treatment at tertiary care hospital LUMHS Jamshoro/Hyderabad. Methods: 93 subjects were studied. Patients were asked to smile fully to measure buccal corridor width with a vernier caliper. The buccal corridor was estimated by multiplying the maxillary interproximal width by the inner lip corner distance by 100. They were divided into 5 modes by buccal corridor percentage. i-e: Buccal corridor 2% (wide smile), Buccal corridor 10% (nearly a wide smile), Buccal corridor 15% (mediocre smile), Buccal corridor 22% (nearly a narrow smile), Buccal corridor above 22% (narrow smile). Angle's malocclusion classification classified all patients. Results: The mean age was 19.18. Males were 34.4% and females were 65.6%. With various types of buccal corridors among them, 37 participants were in a class I malocclusion, 43 were in the class II and 13 were in the class III malocclusion. 14 participants belongs to medium narrow buccal corridors (15.1%), 18 belongs to the medium buccal corridors (19.4%), 47 belongs to the medium broad buccal corridors (50.5%), and 14 belongs to broad buccal corridors (15.1%). The results showed that there was no significant association between these two variables having p-value 0.207. Conclusion: Medium broad buccal corridors were seen more frequently in various types of malocclusion

Optimizing Annual Daylighting Performance for Atrium-Based Classrooms of Primary and Secondary Schools in Nanjing, China

Influenced by educational policies and newly emerging educational philosophies, the proportion of public space is expanding in primary and secondary schools in China. Consequently, the atrium in school design is increasingly drawing attention due to the consideration of space efficiency and its accommodability for diverse activities. Although many studies have already explored the daylighting performance of atriums, the particularities of primary and secondary schools are rarely noticed, which leads to the lack of a reliable basis for a quick judgment in the early design stage. This study used the annual daylight metrics of Spatial Daylight Autonomy (sDA300,50%) and Annual Sunlight Exposure (ASE1000,250 h) as the indicators, built a parametric model in Grasshopper, conducted the simulation using the Ladybug–Honeybee plug-in, and separately performed the linear regression analysis on the three groups of data from the different types of atriums. The results show that in Nanjing’s climate, the north and east sides of atriums are the most suitable orientations for classrooms, and a corridor width of 3 m ensures high-quality daylight for the bottom floors. The optimal design equations for atrium width and length are provided for the three types of atriums, respectively, hopefully, to ensure that classrooms surrounding the atrium can reach the requirement of sDA300,50% ≥ 0.75, and the design recommendations are offered based on the results.

Experimental study of temperature profile in underground corridor of various widths induced by fire in an adjacent compartment

Corridor-compartment fire, i.e., fire plume ejected through the door of the compartment and spread along the adjacent corridor, is a fundamental scientific problem in underground space, which is very important for the evacuation and firefighting. Nevertheless, the relevant studies are still very limited for quantifying the temperature evolutions inside the compartment as well as the corridor ceiling flow induced by corridor-compartment fire scenarios for various compartment door sizes and corridor widths. In the present study, a reduced-scale corridor-compartment experimental model was established, with four opening (door) sizes and eight corridor widths considered. The fuel burning mass loss rate (or instantaneous HRR) and the temperature profile inside the compartment and corridor were measured and analyzed. Results show that: (1) A non-dimensional correlation of the upper-part temperature rise inside the compartment could be found for various opening sizes and corridor widths in over-ventilated and under-ventilated condition, respectively. (2) The temperatures of the ceiling flow at the corner between corridor wall and corridor ceiling increases slowly before over-ventilated and then increases significantly after reaching under-ventilated condition with fire growth, it decreases significantly with the corridor width increasing, due to the change of ventilation condition. A non-dimensional model which considering the effect of corridor width for different opening sizes is proposed for the temperature decay profile of ceiling flow at the corner between corridor wall and corridor ceiling. This model could predict the temperature in underground corridor of various widths induced by a fire in an adjacent compartment, and then analyze and assess the fire thermal hazard on the compartment and corridor.

The geometrical properties of fracture corridors

Fracture corridors are densely fractured zones that may form preferential drains for fluids in the surface and subsurface. Their accurate characterization and modeling are of utmost importance to predictive hydrodynamic models. This paper details their key geometrical attributes and shows that they can be predicted, based on a comprehensive study of surface and subsurface data.The spacing, length and width of fracture corridors all exhibit multifractal characteristics, with a very good consistency between the different data sources. Their width appears to be limited to a maximum of ∼250–300 m, while their fracture density is correlated to their width by a negative power law relationship, but with a significant variability at all scales. The constitutive fractures in the corridors also show multifractal properties. The fracture spacings typically fall in the cm-m range regardless of the corridor size, and moderately increase with increasing corridor size. The fracture heights increase more significantly with increasing corridor size, but with a constant distribution when normalized to the corridor height. All these elements are indicative of typically scale-independent fracture corridor development mechanisms, consistent with a recent model.The data acquired form a key resource from which a new method and tools are proposed for the modeling of fracture corridors in surface and subsurface contexts, with applications to aquifers, hydrocarbon reservoirs or underground CO2 storage sites.

Mammal use of riparian corridors in semi‐arid Sonora, Mexico

AbstractWildlife populations in semi‐arid regions are increasingly challenged by human activities and dependent on the connectivity of riparian corridors for access to surface water. The Madrean Archipelago is a biodiversity hotspot along the arid United States–Mexico borderlands that support both Neotropical and Nearctic wildlife. Infrastructure development (e.g., the border wall and the expansion of Mexican Federal Highway 2) in this region inhibits wildlife movement along the transnational mountain archipelago by disconnecting habitat. To explore the relationship between habitat variables and mammal use of riparian corridors in northern Sonora, Mexico, we collected data from 19 motion‐sensitive cameras between October 2018 and April 2019 and used single‐season occupancy models and Royle‐Nichols abundance estimation models to analyze our data. We recorded 21 species of mammals, including the first sighting of jaguar (Panthera onca) in this region in 25 years. River characteristics (distance from river, riparian corridor width, water availability), remoteness (distance from highway, productivity, elevation), and topographic variety (vertical elevation difference) influenced patterns of occupancy probability and estimated abundance of mammals &gt;1 kg, but the strength and direction of these relationships varied by species. Additionally, intermittently wet desert washes were comparable in species richness to the perennial system. These results highlight the importance of examining physical and biological aspects of habitat. This is especially true when identifying corridors where mitigation structures should be placed to improve wildlife connectivity in biodiversity hotspots like the Madrean Archipelago and semi‐arid ecosystems worldwide.

Defining Sacral Dysmorphism: What Size Corridor Precludes Transsacral Screw Placement.

To determine what size S1-transsacral (TS) corridor is amenable to TS screw placement, as this is commonly used to identify sacral dysmorphism, and to determine if gender, ethnicity, or screw breach is associated with narrow corridors. Retrospective review. Urban level-1 trauma center. Two hundred ninety patients with pelvic ring injuries and preoperative computed tomography (CT) scans. Percutaneous posterior pelvic ring fixation. The width of the S1-TS corridor was measured on the axial (inlet) and coronal (outlet) reformatted CT images. Patients with S1-TS screw fixation and postoperative CT scans were identified. Corridor size, gender, ethnicity, and screw breach were documented. S1-TS screws were placed in 55 of the 290 patients. No S1-TS screws were placed in corridors less than 8 mm. Corridors of &lt;8 mm were present in 114 (39%) of the 290 patients and were not associated with gender or ethnicity. S1-TS screws placed in small (&lt;10 mm) versus large (≥10 mm) corridors did not have a detectable difference in screw breaches (5 of 8, 62% versus 19 of 47 40%; difference, 22%, 95% confidence interval -14% to 52%) or median (interquartile range) screw breach distance [3 mm (2.5-4.8) versus 3 mm (1.2-4.8); difference, 0.9 mm; confidence interval -1.6 to 2.2]. These data are useful for the standardization of sacral dysmorphism reporting based on corridor size. Screw breaches were common irrespective of TS corridor size, emphasizing the small degree of error allowed by this procedure. Prognostic Level III.

Conversion of low-value stands by corridor method in Left-Bank Forest-Steppe, Ukraine

Abstract The aim of the study was to identify the influence of different widths and cardinal directions of felled corridors on the condition and mensuration characteristics of the English oak trees planted there during the conversion of low-value young stands using the corridor method. The study was carried out in oak forests in the forest-steppe zone at a permanent sample plot. The experiment included the conversion of a low-value 8-year-old stand to improve its species composition. The sample plots were laid out in a fertile hardwood forest site. The conversion was realised by felling corridors of various widths (6, 9 and 12 m) and directions and planting English oak trees (Quercus robur L.) within them in rows. For the planted oaks, tending felling was carried out three times: weeding (8 years), cleaning (13 years) and thinning (32 years). A comparative analysis of mensuration characteristics (average height, diameter, growing stock, radial increment, health condition, etc.) was carried out for 32-year-old oak trees grown in the corridors and a part of a low-value stand in the unfelled strips after the tending felling. It was found that the average height and diameter at breast height of oaks in the 6, 9 and 12 m wide corridors of different cardinal directions did not differ significantly. The difference in oak stocks within 6 and 9 m wide corridors of different cardinal directions was also insignificant. The stock differences were statistically significant for 6 and 12 m wide corridors as well as for 9 and 12 m wide ones. The article made recommendations on the width of felled corridors and unfelled strips to effectively convert low-value young stands by the corridor method.

Surgically assisted rapid palatal expansion: is the pterygomaxillary disjunction necessary? A finite element study

Transverse discrepancy is an important factor in determining facial esthetics. It has been shown there is an inverse correlation between the buccal corridor width and the intercanine and intermolar widths. Despite the fact midpalatal expansion is the treatment of choice for growing subjects, for skeletally mature subjects the rapid palatal expansion has limited orthopedic effects, and surgically assisted rapid palatal expansion (SARPE) is preferred. SARPE has shown inconsistencies depending on the surgical technique and/or expander device design. Some authors suggest that median and lateral osteotomies are sufficient to achieve the desired transverse dimensions using the SARPE procedure, while others recommend additional surgical separation of the pterygomaxillary junction. There are still controversies regarding the pterygomaxillary sutures (PMS) disjunction effect. Therefore, this study aimed to evaluate the displacement and stress distribution of the craniofacial structures resulting from SARPE, either with or without PMS osteotomy, using two different expander design (tooth-borne and tooth-bone-borne) using finite element method and finite element analysis (FEM/FEA). Regardless of the maxillary expander device type, both SARPE surgical techniques effectively produced maxillary expansion. SARPE with PMS osteotomy presented parallel maxillary expansion, and reduced stress values in the craniofacial and maxillofacial structures.

Delimitation of ecological corridors in a highly urbanizing region based on circuit theory and MSPA

Habitat fragmentation, a contributor to biodiversity degradation in urbanized regions, will result from rapid urbanization. Due to the low quality of habitats and the complexity of land use in high-density cities, traditional ecological corridor development approaches may not be viable for urban contexts. Furthermore, unlike other ecological corridors, the width of urban ecological corridors is not fixed due to very constrained land use and a high density of structures in urbanized areas. However, we discovered few studies on how to build urban ecological corridors in densely populated areas. Aside from that, earlier studies primarily concentrated on identifying potential paths for ecological corridors, with the spatial range of ecological corridors typically being determined subjectively. The goal of this research was to develop an integrated approach for determining the suitable areas of ecological corridors in a rapidly urbanizing region. Firstly, key species for urban ecological corridors were identified and Morphological Spatial Pattern Analysis (MSPA) was applied to identify core areas and established corridors in the city, which was then integrated with NDVI and InVEST to construct resistance surfaces. Potential corridor paths were identified and graded for importance by Linkage Mapper. Finally, our research established a metric and indicators system, four indicators were set in this framework: the suitable width for animal migration, the maximum cost-weighted distances animals can migrate, areas with high mobility potential, and areas with greatest restoration opportunities. A total of 33 urban ecological sources and 63 ecological corridors were identified. The corridor is only 10 m wide at its narrowest point and 100 m at its widest point. Delimiting the appropriate areas of ecological corridors can provide spatial guidance for the implementation of corridors and ensuring ecological security in densely populated areas.

Pedestrian counterflow in a floor field cellular automaton model coupled with an evolutionary game

We study the bidirectional pedestrian flow in a straight corridor using a floor field cellular automaton model, where a game-theoretical framework is exclusively introduced to deal with conflicts that multiple pedestrians are trying to move to the same target position. The pedestrians can behave as either cooperators or defectors, depending on whether they show gentle or aggressive in face of conflicts, respectively. When competing with cooperators, a defector always obtains a relatively greater payoff, characterizing the advantage of occupying the preferred vacant cell, while a reduced payoff factor δ is introduced for mutual defection due to the possible injuries by aggressiveness. We study how the pedestrian counterflow dynamics depends on δ, the corridor width W and the anticipation floor field parameter k A. It is found that the average separation time of the pedestrians displays a resonance-like behavior as a function of δ, irrespective of the width of the corridor as long as jam does not happen. The way of dealing with conflicts has no qualitative effect on the lane formation, where the jam probability mainly depends on the parameters W and k A as well as the pedestrian density. A large value of k A means a strong tendency to avoid potential future collisions and suppress the overtaking motivation, but, at a cost, increases the average separation time of the two groups of pedestrians when the width of the corridor is not so narrow. Our results provide a meaningful perspective on the understanding of the process of lane formation and jam dissolution in the bidirectional pedestrian flow, and may shed light on designing policies to improve the efficiency of passing through.

Optimal Routing of Wide Multi-Modal Energy and Infrastructure Corridors

A multi-modal corridor accommodates multiple modes of energy and transportation infrastructure within the same right-of-way. The existing literature on corridor routing in raster space often focuses on one mode with no consideration of the width. This is not a realistic assumption, especially if multiple modes are to co-exist within the same wide right-of-way. Moreover, newer routing methods that consider corridor width cannot take into account multi-modality and the arrangement of modes within a corridor. We developed two multi-modal wide-corridor routing methods using raster data. In the first method, the cost rasters of all modes are weighted and aggregated into a single composite on which a wide LCP is found. This wide LCP is then divided among the modes based on the desired arrangement. The second method uses a directed transformed graph in which the weight of each edge is calculated using different layers of cost data based on the edge direction, the desired widths and arrangement of the modes. Comparative analyses using synthetic datasets show the superior performance of the second proposed method in finding a muti-modal corridor in comparison with the first mode, and in finding a single-modal corridor when compared to the existing methods.

Quantitative evaluation of the rebuilding costs of ecological corridors in a highly urbanized city: The perspective of land use adjustment

Well-functioning ecological corridors are critical for conserving biodiversity in areas undergoing increasing habitat losses and ecosystem fragmentation. Although it is essential to rebuild broken corridors by land use adjustments, related discussions of spatially explicit delineations of to-be-adjusted lands and quantitative adjustment costs are rare. Based on a widely adopted minimum cumulative resistance (MCR) model, we simulated the potential ecological processes and identified ecological corridors in a rapidly urbanized city, namely, Nanjing, in eastern China. We then analysed the corresponding land use and cover changes (LUCCs) from 2000 to 2015 and quantitatively calculated the costs of rebuilding the indicated corridors based on the indication of the amount/spatial distribution of to-be-adjusted lands and their different standards of related adjustment. The results indicated that most obtained corridors were along continuous waters, but LUCCs still occurred within them; the spatial expansion of urban lands dominated, especially in the suburban areas and outer buffers of the ecological corridors. The rebuilding costs increased significantly, and urban land adjustments dominated these increases. Spatially, most costs were associated with suburban areas, and the costs increased obviously as the corridor width increased. Based on the comprehensive consideration of ecological suitability and economic rationality, we found that 200 m was the most appropriate width for rebuilding ecological corridors, as it can both meet the demands of local species and balance the local public budget. We explored methodologies used to identify potential ecological corridors and quantitatively evaluate the costs of rebuilding them, thus providing a basis for implementing practical and feasible land use adjustments addressing ecological suitability and economic rationality.
