The Effect of Disability Insurance Receipt on Labor Supply

This paper estimates the effect of Disability Insurance receipt on labor supply. Exploiting the effectively random assignment of judges to disability insurance cases, we use instrumental variables to address the fact that those allowed benefits are a selected sample. We find that benefit receipt reduces labor force participation by 26 percentage points three years after a disability determination decision, although the reduction is smaller for those over age 55, college graduates, and those with mental illness. OLS estimates are similar to instrumental variables estimates. We also find that over 60% of those denied benefits by an Administrative Law Judge are subsequently allowed benefits within 10 years, showing that most applicants apply, re-apply, and appeal until they get benefits. Next, we estimate a dynamic programming model of optimal labor supply and appeals choices. Consistent with the law, we assume that people cannot work and appeal at the same time. We match labor supply, appeals, and subsequent allowance decisions predicted by the model to the decisions observed in the data. We use the model to predict labor supply responses to benefit denial when there is no option to appeal. We find that ∗Comments welcome at jae.song@ssa.gov and efrench@frbchi.org.

Comparing abiotic and biotic parameters when assessing streams within a geologically diverse area (Bartow County, GA)

During the summer of 2000, we sampled twenty-two stream sites in Bartow County (Georgia) for fish, macro-invertebrates, water quality, habitat condition, and bacterial indicators as part of a county-wide watershed assessment. Three major geological regions occur within the county (to the west rocks are mainly limestone, to the north shales and sandstones, and to the east and southeast harder metamorphic rocks). Because the county is so geologically diverse yet all sites are within the same drainage basin, this data set provides a rare opportunity to examine the influence of watershed geology within a relatively small geographic area on parameters and metrics traditionally used to assess anthropogenic impacts. Principal component analysis (PCA) and other comparisons indicate that most biotic and abiotic parameters over all sites are related to one another in ways expected among sites that vary due to anthropogenic impacts. Multimetrics developed for fish and for invertebrates reflected trends along the primary PCA 'water quality' factor (turbidity, suspended solids, and BOD), whereas site geology did not reflect trends across this factor. As expected dissolved ions (as well as alkalinity and pH) were strongly related to watershed geology, but other less obvious water quality parameters such as nitrate were also associated with geologic location. Most individual metrics that are traditionally used to assess invertebrate and fish communities did not appear to be influenced by geology, but rather by anthropogenic habitat and water changes. In addition, differences in taxonomic composition of invertebrate communities were associated with watershed geology. Any given invertebrate community within the western limestone region was most similar (based on similarity indices of species composition) to other communities within this same region. Communities within the other two regions were not similar to western communities, but not distinctly different from each other. Because water chemistry between streams of western limestone and streams of northern shale-sandstone are more similar, geological influences on invertebrate species distribution may reflect physical stream characteristics (such as streambed morphology and substrate characteristics) rather than water chemistry. While underlying geology strongly affected many water quality parameters, biotic measures were relatively independent of these water quality effects, indicating biotic parameters are reliable in assessing degradation in a geologically diverse basin.
Multifractal Auditory Stimulation Promotes the Effect of Multifractal Torso Sway on Spatial Perception: Evidence from Distance Perception by Blindwalking

Abstract Stimulation and movement interact non-linearly across multiple scales—a point empirically and quantitatively available through multifractal structure. Multifractal movements might implicate multifractal stimulation. Previous correlational modeling of accelerometry-measured torso movements during blindwalking indicated that multifractality in movement predicts distance-perceptual judgments. We now experimentally tested whether multifractal stimulation interacted with multifractal torso movement to support distance perception. We edited music-like sounds to manipulate multifractal non-linearity in auditory stimulation through headphones to participants perceiving distance by blindwalking—with eyes closed both during Lap-1 distance instruction and Lap-2 distance replication. Stimulation non-linearity significantly interacted with torso movements to predict distance-replication judgments. Low stimulation non-linearity showed no effect. Medium stimulation non-linearity interacted with Lap-2 torso non-linearity to produce over-/underestimation of shorter/longer distances. Higher auditory non-linearity led Lap-2 distance replication enlisted longer time scales, drawing on prior torso non-linearity, i.e. from Lap 1, and producing overestimation proportionally with a greater standard deviation of torso movements. Distance perception by blindwalking appears more accurate under medium rather than excessive non-linearity, resonating with previous evidence that walking engenders less multifractality than other movements. Movement-dependence of stimulation is also unsurprising to ecological-psychology wisdom. However, to our knowledge, present results constitute an unprecedented step toward elaborating movement-dependence to multifractal-geometrical approaches to perception.
Whelks, rock-snails, and allied: a new phylogenetic framework for the family Muricidae (Mollusca: Gastropoda)

Abstract The worldwide distributed neogastropod family Muricidae comprises more than 1800 extant species of whelks, rock-shells, murex-shells, drill-shells, and coral-shells. Despite several attempts at a taxonomic revision based on morphological characters, the systematics of this family is still largely debated. Here, we present a molecular revision of the family Muricidae based on the largest dataset analysed so far, which comprises 384 specimens representing 360 species and includes, for the first time, all the currently recognised subfamilies. A molecular dataset of cox1, 12S rRNA, 16S rRNA, and 28S rRNA genetic markers and six fossil-based calibration points were used to produce time-calibrated phylogenetic reconstructions, using a Maximum Likelihood approach. Our results confirmed the monophyly of most of the accepted subfamilies, suggested a revision of the taxonomic composition of Muricopsinae and Muricinae, and highlighted some lineages not immediately comprised in any of the recognised subfamilies. The origin and early diversification of the subfamilies of Muricidae occurred between 32 and 60 million years ago.
A Prospective Randomized Interventional Study to Establish the Role of Bovine Lactoferrin in Helicobacter Pylori Infection

Helicobacter pylori (H. pylori) are gram-negative spiral bacterium that surrounds itself in the epithelial surface of the stomach. It is found to be the most common bacterial infection affecting the population worldwide approximately 50%. The elimination of H. pylori is not only an important component in the healing of peptic ulcers, but also to decreases their recurrence and reduces the rate of gastric carcinoma. Eradication of H. pylori is currently recommended in numerous guidelines for the treatment of all these associated diseases. In the last two decades, attention has focused on the potential role of bovine lactoferrin (bLf) in the therapy of various gut disorders. bLf, a multifunctional iron-binding glycoprotein that is found in the milk, mucosal secretions (e.g., saliva, tears, bile), pancreatic and seminal fluids, and specific granules of the polymorphonuclear leukocytes in humans. Proton-pumpbased triple therapy (PpTT) is the most commonly accepted H. pylori treatment, which consists of a twice-daily proton pump inhibitor (PPI) such as esomeprazole or pantoprazole or omeprazole; clarithromycin or amoxicillin with tinidazole for 7-14 days. The aim of our study was to evaluate the efficacy of Bovine lactoferrin, administered orally along with triple therapy on H. pylori colonization in humans by a prospective randomized controlled study. 75 Patients with H. pylori positive were recruited and treated as per the protocol for 2 weeks. The subjects were randomized into 2 groups based on inclusion and exclusion criteria, interventional group received bovine lactoferrin at a dose of 100mg twice daily along with triple therapy for 14 days and the control group received, triple therapy for the same period of 14 days. The reduction in symptoms were analyzed by using a set of questionnaire and scored by using Global Overall Symptom Scale (GOS) both prior and post treatment. The eradication of H. pylori was confirmed by (13c) Urea breath test (UBT) that has shown the eradication rate of 76.2% in interventional group and 61.1% in control group. This study results had indicated that the group received bovine lactoferrin had shown significant improvement in the H. pylori eradication. This result can be used to conclude that the role of bovine lactoferrin in the reduction of symptoms and eradication of H. pylori infection by focusing on the relatively high cure rate, good compliance to the treatment and higher quality of life.
Prototype of a metasurface scale for an optical rotation angle sensor

The use of metasurfaces as scales of optical rotation angle sensors (encoders) makes it possible to reduce their overall dimensions by several orders of magnitude. The paper briefly discusses one of the possible options for implementing a rotation angle sensor with a scale from a metasurface. As a scale it is proposed to use a metasurface – a dielectric onedimensional subwavelength array designed to operate in the infrared spectral range (at a wavelength of 1.5 microns). By the finite element method, a prototype of an optical angular scale from a metasurface has been developed by computer modeling. The results of an experimental study of a prototype of an optical angular scale from a metasurface are presented. The metasurface was made of tantalum oxide and deposited on a quartz glass substrate. For the convenience of the study, the size of the scales was set to 400 × 400 microns, but if necessary, it can be reduced by more than an order of magnitude. The dependences of the transmission spectra of the prototype scale on its rotation angle are experimentally investigated.
Competitive Advantage Based on Green Intellectual Capital and Green Innovation

In the limited use of natural resources, companies must use the intelligence of their human resources to produce environmentally friendly and energy-efficient products and avoid environmental damage for the company's survival. This study investigates how green intellectual capital and innovation affect the competitive advantage of companies operating in the primary consumer goods industry. The research question is whether companies need more natural resources that are limited in quantity and quality. To ensure business sustainability, increased green intellectual capital, expensive green innovation, and long-term research are needed. Primary consumer goods sector manufacturing companies listed on the Indonesian Stock Exchange (BEI) from 2018 to 2020 are the subject of the research used. With the purposive sampling method, 62 companies were used, thus obtaining 179 samples. Research data is obtained from annual reports, sustainability reports, or company websites on the Indonesian Stock Exchange (BEI). The data analysis model is track analysis. Studies show that green intellectual capital affects competitive advantages, while green innovation does not. Innovative green innovations must be well integrated into the corporate accounting system to ensure corporate survival. This will involve increased research and development to improve resource access by increasing R&D.
Late Triassic continental vertebrates and depositional environments of the Fleming Fjord Formation, Jameson Land, East Greenland

A diverse assemblage of fossil vertebrates has been discovered in the Fleming Fjord Formation (Malmros Klint and Ørsted Dal Members) in East Greenland between latitudes 71°15'N and 71°50'N. The fauna includes several species of mammals as well as prosauropod (Plateosaurus) and theropod dinosaurs, turtles (cf. Proganochelys), pterosaurs, aetosaurs (Aetosaurus ferratus, Paratypothorax andressi), labyrinthodont amphibians (Gerrothorax, Cyclotosaurus and possibly other taxa) and fishes (including sharks, actinopterygians, coelacanths and lungfish). The association of the genera Aetosaurus, Plateosaurus, Proganochelys, Cyclotosaurus and Gerrothorax is shared with well known European Norian faunas, and confirms the paleogeographic proximity of Greenland and Europe during Late Triassic time. On this evidence, the Ørsted Dal Member may be estimated to be at least as old as mid-Norian, but a comparable age estimate for the underlying Malmros Klint Member cannot be made on the basis of the fauna as presently known. The Malmros Klint Member is characterized by composite cyclicity with four orders of cycles involving silt-rich, ephemeral lake or playa-mudflat systems, loess beds, wave-reworked sand flats, flat pebble conglomerates and paleosols. The rhythmicity and thickness ratios of the beds are evidence that depositional conditions were controlled by Milankovitch cycles, with climatic conditions varying from humid, to dry with seasonal rainfall, to arid. Cyclical sedimentary conditions and climatic fluctuations appear to have continued during the subsequent deposition of the overlying Ørsted Dal Member.
Three-Dimensional Numerical Model for Double-Porosity Media with Two Miscible Fluids Including Geomechanical Response

AbstractThe finite-element formulation of a coupled fluid flow and geomechanics for two-phase fluid flow through fractured porous media are presented. Two porosities, pores and fractures, and five phases are introduced. The two fluids are taken as wetting and nonwetting. The governing equations are derived based on the theory of poroelasticity, the effective stress principle, and the balance equations of mass and momentum, taking into account the solubility of nonwetting fluid into wetting fluid. Spatial and temporal discretization of the governing equations has been realized through the Galerkin method and the finite-difference technique, respectively. A three-dimensional numerical code has been developed and validated based on previously published data. Various applications of the model have been demonstrated through three field-scale examples.

Microbial stratification in deeply buried marine sediment reflects changes in sulfate/methane profiles

We examined sediments collected at Ocean Drilling Program (ODP) Leg 201 Site 1229 on the Peru Margin for microbial populations throughout the sediment column. Heterotrophic cultivation from these sediments yielded numerous colonies from various depths, including 49 bacterial isolates. At ODP Site 1229, there are significant interfaces of sulfate and methane, across which microbial cell numbers increase substantially. At these sulfate/methane transition zones (SMTZs), however, we observed a decrease in the success rate for the cultivation of bacterial colonies. Utilizing both direct plating and enrichment in different media, we cultivated isolates from the upper SMTZ around 30 m below seafloor (mbsf); however, similar attempts yielded no colonies from within the lower zone at 85 mbsf. The phylogenetic relationships of the 16S rRNA gene sequences for the isolates were determined and most were related to other organisms and sequences previously found in the subsurface belonging to the γ‐Proteobacteria, cytophaga–flavobacterium–bacteroides, high G + C Gram‐positives, and Firmicutes groups. The most diverse group of isolates from Site 1229 was found between the SMTZs at 50 mbsf. ODP Leg 201 Site 1228 was examined for comparison and yielded an additional 18 isolates from 16 to 179 mbsf that were similar to those found at Site 1229. Direct plating at Site 1228 also showed decreased colony formation in the area of sulfate/methane transition. Our results suggest that heterotrophic bacterial populations are affected by SMTZs in deeply buried sediment.
Foreign Direct Investment and Productivity Spillovers Evidence from the Spanish Experience

The aim of this paper is to analyse the impact of Foreign Direct Investment (FDI) on firm productivity using an establishment-level panel of Spanish manufacturing industry that spans the period 1990-1994. The key question concerns the elements that enable domestic firms to capture the positive spillovers associated with the presence of foreign firms. We use Research and Development (R&D) expenditure and trade data to represent the capacity of local firms to reap the benefits from FDI. Our results fail to identify positive spillovers for local firms while a negative correlation is detected in low R&D activities. Further evidence shows that positive externalities have been mainly captured by foreign affiliates. Overall, the general effects of FDI remain very limited in absolute terms compared to similar studies of developing countries.
The Influence of Adhesive Strategy, Type of Dental Composite, and Polishing Time on Marginal Gap Formation in Class I-like Cavities

Even after more than six decades of dental composite invention (1962), there is still controversial information about the time in which composite restorations should be polished in order to avoid marginal gap formation at the tooth–composite interface. The aim of the present study was to analyze the influence of adhesive strategy, the type of dental composite, and polishing time on marginal gap formation (%MG) at the tooth–composite interface. Class I-like cavities were hybridized with a universal adhesive system (Single Bond Universal) through two strategies: selective enamel etching (SEE) or self-etching mode (SEM). Cavities were filled with two types of dental composites: nanofilled (Z350) or bulk fill (Filtek One Bulk Fill—ONE), and polishing was performed immediately or delayed for 7 days (n = 5). %MG was evaluated by using a 3D laser confocal microscope. As flexural modulus (FM) and degree of conversion (DC%) are determinants of marginal integrity in dental composite restorations, these properties were evaluated for both composites. Data were analyzed by ANOVA and Tukey’s HSD test (α = 0.05). Cavities hybridized following the SEE strategy presented lower %MG (p < 0.05). Z350 showed higher %MG than ONE (p < 0.05). There was no difference in %MG between the polishing times when the SEE strategy was used (p > 0.05). Z350 presented higher FM than ONE (p < 0.05). DC% was found to be not significant (p > 0.05). The results suggest that selective enamel etching (SEE) is a better strategy for producing less %MG in composite restorations with enamel margins irrespective of the time in which the restoration is polished.
Classification of forest vegetation in Yaraligöz Education and Observation Forest, Kastamonu, Türkiye

Abstract. Karaköse M, Terzioglu S. 2023. Classification of forest vegetation in Yaraligöz Education and Observation Forest, Kastamonu, Türkiye. Nusantara Bioscience 15: 161-171. Forest ecosystems, which contain approximately half of the 12,975 plant taxa known to be distributed in Türkiye, are very important in terms of biological diversity. The fact that forests are seen as wood-producing ecosystems and have been planned for these purposes for many years has resulted in forests being kept away from being evaluated in terms of ecosystem and socio-economic aspects. Today, forest management plans have begun to be prepared in which all components of the forest are considered, and biological diversity is reflected. Based on this understanding, this investigation was performed during 2011-2012 to analyze the forest vegetation of Yaraligöz Education and Observation Forest. The study area is located in the north-western part of Türkiye within the Euro-Siberian phytogeographic region. Phytosociological studies were carried out using the classical Braun-Blanquet approach, and 51 relevés were collected from the research area. The database contains 184 vascular plant taxa, dominated by the Euro-Siberian elements and Hemicryptophytes. The relevés were classified using the Modified TWINSPAN, and the forest vegetation types' distribution was analyzed using non-metric multi-dimensional scaling. A comprehensive comparison among all described syntaxa within the study area and other closely related forests was provided. Topographic factors and mean Ellenberg indicator values were evaluated to interpret the ecological relationships among forest plant associations. Four associations, two (Daphno pontica-Pinetum hamatae and Galio rotundifolii-Abietum equi-trojani) of which are new syntaxa to science, were defined as belonging to the Euxine Province within Erico-Pinetea, Carpino-Fagetea sylvaticae, Quercetea pubescentis, and Vaccinio-Piceetea. The distribution of these four forest associations was mostly affected by light intensity, nutrients, moisture content, and altitude. The results of this vegetation study provided precious knowledge for monitoring vegetation change and nature conservation projects in the Yaraligöz.
