The Impact Outdoor Recreation Activities on Individuals with Physical DisabilitiesThe purpose of this synthesis was to review the literature on the impact of outdoor recreation activities on individuals with physical disabilities. Participation in outdoor recreational activities should be accessible to everyone. Participation in outdoor recreation improves an individual’s physical, mental, and social well-being. However, people with physical disabilities cannot participate due to access limitations. Specifically, they face barriers and constraints that may limit them from participating. Through the review of literature, it was determined that individuals with physical disabilities participating in outdoor recreation experienced benefits and constraints. In addition, some facilitators motivate them to participate. Lastly, the studies provided ways to help make communities more accessible for individuals with physical disabilities.

The “Accidental Candidate” Versus Europe’s Longest Dictator: Belarus’s Unfinished Revolution for WomenWomen in Central and Eastern Europe have made gains as presidents and prime ministers. A notable exception to this is Belarus, where President Alyaksandr Lukashenka, the longest dictator in Europe, has tightly clung to power since 1994. Sviatlana Tsikhanouskaya surprised many when she threw her hat in the ring for the 2020 presidential election. This article asks how Tsikhanouskaya arose as the 2020 opposition candidate and how gender shaped the campaign. Gender played a central role in her being able to stand in the election. Her husband had been a leading presidential candidate but was imprisoned by the regime. Like women who rose to executive leadership positions, Tsikhanouskaya ran in her husband’s place. Lukashenka permitted her candidacy because he did not see her as a political threat. Lukashenka regularly dimin‐ ished her candidacy using sexist rhetoric. Tsikhanouskaya’s own campaign highlighted more traditionally feminine traits such as being a nurturer, unifier, and non‐power seeking, and only being in politics by chance. Referring to herself as an “accidental candidate,” she made it clear that she sought to unify the Belarussian people against the dictatorship and would step aside after this was accomplished. As de facto opposition leader, she continues to highlight these more feminine qual‐ ities and craft a less threatening image.

Factors associated with extirpation of the last Northern Sunfish (Lepomis peltastes Cope, 1870) population in western New York State, USAThe Northern Sunfish (Lepomis peltastes Cope, 1870) is threatened in New York state, USA, but this was not the case before 1940 when the NY Biological Survey documented the species at scattered, specialized habitats in six watersheds in the central and western parts of the state. After 1940 the historic populations could not be detected, but a new population was discovered in 1974 in lower Tonawanda Creek and the nearby Erie Canal. Northern Sunfish, and a few of their hybrids with other Lepomis species, were caught at these locations during irregular sampling through 2009, but no Northern Sunfish were caught after 2009. The objectives of our study were to: (1) Determine the extent of Northern Sunfish hybridization with other Lepomis species, and (2) Evaluate how well identifications of Lepomis species and their hybrids agreed among field keys, morphometric measurements and meristic counts, and genetic methods. In 2013, we collected Northern Sunfish (descended from fish captured in lower Tonawanda Creek from 2006-2009) from NY State Department of Environmental Conservation rearing ponds, plus wild Green Sunfish (L. cyanellus Rafinesque, 1819), Pumpkinseed (L. gibbosus Linnaeus, 1758), Bluegill (L. macrochirus Rafinesque, 1819), and suspected Lepomis hybrids from lower Tonawanda Creek. Ultimately, 91 fish were identified using field keys, morphometric-meristic analysis, and mtDNA and nuclear DNA analysis. Assuming genetic analysis provided accurate identification, we found 7 Bluegill×Northern Sunfish, 8 Bluegill×Pumpkinseed, 13 Bluegill×Green Sunfish, and 3 Green Sunfish× Pumpkinseed hybrids in our sample (female parent listed second in these crosses). Keyed and morphometric-meristic identifications did not differ in accuracy and averaged 81% of genetic identification accuracy. After Northern Sunfish stocking (not in our study area) and sampling from 2008 to 2018 in several watersheds with appropriate habitat and no recaptures after 2014, we conclude that the Northern Sunfish is extirpated in western New York state. HIGHLIGHTS • While populations of Northern Sunfish (Lepomis peltastes) existed in several New York state watersheds before 1940, only one, discovered in 1974, persisted in small areas of lower Tonawanda Creek and the nearby Erie Canal. • Despite high effort, no Northern Sunfish were captured after 2009 in the places they had occupied since 1974. • Because many Northern Sunfish, all descended from wild fish in lower Tonawanda Creek and the Erie Canal, exist in two New York state hatchery ponds, we recommend attempting restoration in their former habitat by stocking.

Influences of seasonality and habitat quality on Great Lakes coastal wetland fish community composition and dietsGreat Lakes coastal wetlands (GLCW) have been severely degraded by anthropogenic activity over the last several decades despite their critical role in fish production. Many Great Lakes fish species use coastal wetland habitats for spawning, feeding, shelter, and nurseries throughout the year. The goal of our study was to compare GLCW fsh community composition in the spring, summer, and fall months and investigate how water quality relates to fish diversity, the presence of functional groups, and juvenile fsh diets. We summarized fsh data collected from GLCW across the basin and used the coastal wetland monitoring program’s water quality-land use indicator to quantify water quality. Basin-wide, we found taxonomic and functional group diferences in community composition among three sampling seasons, as well as across the range of water quality. Water quality was positively associated with the abundance of small cyprinids and the relative abundance of some habitat and reproductive specialists. Seasonal differences were also observed for many of these functional groups, with more temperature- and pollution-sensitive fishes captured in the spring and more nest-spawning fishes captured in the summer and fall. In our diet study, we found that age-0 fish primarily consumed zooplankton in the fall, whereas age-1 fish primarily consumed macroinvertebrates in the spring. Moreover, wetland quality was positively associated with trichopteran prey abundance. We concluded that taxonomic and functional composition of fish communities in GLCW vary markedly with respect to water quality and season. Thus, a full understanding of communities across a gradient of quality requires multi-season sampling.

Evaluating the use of hyperspectral imagery to calculate raster-based wetland vegetation condition indicatorField observations and measurements of wetland plants have traditionally been used to monitor and evaluate wetland condition; however, there has been increasing use of remote sensing applications for rapid evaluations of wetland productivity and change. Combining key aspects of field- and remote sensing-based wetland evaluation methods can provide more efficient or improved biological indices. This exploratory study set out to develop a raster-based Wetland Vegetation Condition Indicator system that used airborne hyperspectral imagery-derived data to estimate plant-community quality (via wetland classification and Coefficient of Conservatism) and vegetation biomass (estimated using the Normalized Difference Vegetation Index). The Wetland Vegetation Condition Indicator system was developed for three Lake Ontario wetland areas and compared to a field-based floristic quality index and a dominant-plant based Floristic quality indexdom. The indicator system serves as a proof-of-concept that capitalized on the spatial and spectral attributes of high-resolution imagery to quantify and characterize the quality and quantity of wetland vegetation. A Pearson correlation analysis showed moderate r values of 0.59 and 0.62 for floristic quality index and floristic quality indexdom, respectively, compared to the indicator method. The differences are potentially due to the spatial resolution of the imagery and the indicator method only accounting for the dominant plants within each assessment unit (pixel), therefore disregarding understory plants or those with low abundance. However, the multi-metric Wetland Vegetation Condition Indicator approach shows promise as an indicator of wetland condition by using remotely sensed data, which could be useful for more efficient landscape-scale assessments of wetland health, resilience, and recovery.

Reframing Social Work Education Using OERSocial work is, by definition, a profession devoted to the pursuit of social justice and the eradication of oppression, inequity, disparities, and other forms of injustice. Social workers are focused on the empowerment of marginalized people and communities and are expected to adhere to clear standards of ethical and competent practice. Additionally, the title of “social worker” is earned through the successful completion of social work education, either on the undergraduate or graduate levels. These social work programs are, in the United States of America, accredited by the Council on Social Work Education (CSWE), which periodically revises and updates its Educational Policy and Accreditation Standards (EPAS)1 and monitors the adherence of each accredited program to these standards. Essentially, CSWE determines the learning of every social worker in the United States.

Failure of Walleye Recruitment in a Lake with Little Suitable Spawning Habitat Is Probably Exacerbated by Restricted Home RangesOver eight million walleye (Sander vitreus) fry are stocked annually in Honeoye Lake, a small lake in the Finger Lakes Region of west-central New York. The objectives of our study were to find and describe the spawning locations and habitats of walleye and describe the spawning locations and habitats of walleye and to assess natural production of fry. Twenty-thee adult walleye were radio-tagged and tracked for up to 2.5 years. They established relatively small home ranges (24-188 ha) and moved more during the three-week spawning season (149 m/d)than the rest of the year (37 m/d) No naturally produced walleye eggs were collected in the Honeoye inlet channel where adults congregated during the 2002 and 2003 spawning season, nor were fry collected in the lake until after 8.7 million were stocked in 2003. Radio-tagged walleye exhibited homing and site fidelity in Honeoye Lake but not in the few known areas with suitable spawning substrates (no eggs were collected at these locations.

Two Congener‑specifc Models Estimate PCB TEQ Hazard to American Mink (Neovison vison) Living near a Western New York CreekWe present two models to monitor the health of ecosystems by assessing hazard from a persistent organic compound to a top predator species. Our diet model predicts the dietary exposure of American Mink (Neovison vison) to PCB toxic equivalents (TEQ) by combining concentrations in their prey using weighted average proportions consistent with literature-based mink diets. Our bioaccumulation model predicts the dietary exposure of mink to PCB TEQ based on each congener’s total concentration in water (dissolved plus particulate fractions), the octanal/water partition coefcient (log Kow) of the compound, and the trophic levels of prey taxa. Both models predict mink dietary concentrations which can be directly compared with each other and with lowest observable adverse efects concentrations (LOAECs) to assess chronic and acute hazards of PCB TEQ to mink. By our choice of certain parameters in the bioaccumulation model, we forced it to match the diet model within less than 5% for Eighteenmile Creek in western New York State. When the two models were used for a similar creek about 25 km away, the diferences in their predictions were of the same magnitude.

Levels of Bioaccumulative Chemicals of Concern in Air, Water, Sediment and Sentinel Species of the Rochester Embayment of Lake OntarioIn the 1980s, the International Joint Commission (IJC) began the process of creating and implementing remedial action plans (RAPs) in 43 areas of concern (AOCs) throughout the Great Lakes Basin of Canada and the United States. An area identified as an AOC violated one or more of 14 “use impairments” listed by the IJC. For example, “fish and wildlife consumption advisories” due to the presence of bioaccumulative chemicals of concern (BCCs) is a use impairment identified for the Rochester, NY Embayment of Lake Ontario AOC.

Eighteenmile Creek Area of Concern Mink Prey Survey and Oak Orchard Creek Add-onIn the Great Lakes Basin, the International Joint Commission (IJC) has identified 43 Areas of Concern (AOC) where pollution from past industrial production and waste disposal practices has created hazardous waste sites or contaminated sediments. Beneficial Use Impairments (BUI) have been identified for each AOC, and for an AOC to be delisted removal of each of its BUIs must be documented. This study assessed whether chemicals of concern (COC) could negatively impact mink populations along Eighteenmile Creek (EMC) and addressed two BUIs: Degradation of Fish and Wildlife Populations and Bird or Animal Deformities or Reproductive Problems. Criteria for removing these two BUIs in the EMC AOC are in Table 1 and definitions of acronyms used in this report are in Table 2.

Fen development along the southern shore of Lake OntarioFen development along a drowned-river-mouth tributary to Braddock Bay, Lake Ontario was studied to address its formation. Nested piezometers were installed to assess groundwater contributions and obtain water chemistry samples. Soil and geology information came from existing sources. We converted paleo lake levels from published reports to IGLD1985 and calendar years BP for use in analyzing vegetation changes over time using a combination of peat-core plant macrofossils and modern surveys. Piezometer data showed upward discharge, water at 3-m depth had pH 6.9, specific conductivity of 508 lS/cm, and alkalinity 206 mg/L as CaCO3. Hydraulic head and mineralized water chemistry decreased at shallower depths. Vegetative development began 1790 cal yr BP with sedges and brown moss when land surface was 0.135 m above lake level. Lake levels increased, and by 1590 cal yr BP, water was 0.17 m deep and sedges were joined by shoreline emergent species. Water depth then increased to 0.525 m but began decreasing as lake levels fell. Peatland species appeared around 810 cal yr BP when water depth was reduced to 0.225 m. About 585 cal yr BP, additional peatland species appeared when land surface was 0.075 m above lake level. Sphagnum became prominent 80 cal yr BP (0.81 m above lake level), representing 67 % mean cover in modern vegetation. Isolation of the surface from calcareous groundwater resulted in transition from rich fen to poor fen. These wetlands are rare in the lower Great Lakes and deserve protection of their characteristic hydrology, water chemistry, and vegetation structure.

Testing restoration methods for Lake Ontario wetlands at a wetland scaleSedges and grasses have a competitive advantage over cattails at higher elevations in Great Lakes wetlands where periodic low lake levels result in soils too dry to support cattails. Regulation of Lake Ontario water levels eliminated low lake-level years, resulting in cattail invasion. At a wetland scale at two Lake Ontario sites, we tested restoration methods by dredging channels through cattails, using spoil materials to create mounds suitable for sedge/grass growth, seeding mounds, and controlling cattails (T. glauca) using methods adapted from experimental studies. Soil moisture and subsidence of mound soils were monitored. Vegetation was sampled pre-restoration and in shoreline sedge/grass meadow, emergent, and mound zones for two years following implementation. Although spoil mounds decreased in elevation at both sites, soil moisture increased more at the site with greater subsidence. Mean percent cover and ramet counts of cattails were reduced in sedge/grass and emergent zones at both sites. Mounds with greater soil moisture held more cattails post-construction. Across years at both sites, Carex lacustris and Calamagrostis canadensis increased in the sedge/grass meadow zone with reduction in Typha; Calamagrostis increased on the mounds. Key factors affecting results were cattail litter and, on the mounds, a second year of seeding with in situ cold, moist stratification, as well as soil moisture related to subsidence. Recommendations for future restorations include conducting more detailed soil surveys to assess potential subsidence, dredging wider and deeper channels to provide spoil for higher mounds, actively controlling invasive species, and conducting additional years of post-restoration data collection. 2022 International Association for Great Lakes Research.

Wetland Restoration in Typha -Dominated Braddock Bay of Lake OntarioThe barrier beach at the Braddock Bay wetland on Lake Ontario was lost to erosion. Without the protective barrier, the area of vegetated wetland was reduced by wave attack. Lake-level regulation implemented in 1960 resulted in cattail (primarily hybrid Typha × glauca), invasion and loss of sedge-grass meadow habitat. As part of the Rochester Embayment Great Lakes Area of Concern, Braddock Bay was targeted for restoration by the U.S. Army Corps of Engineers. The plan included reducing coverage by cattails, construction of channels and potholes to improve wildlife access to the wetland, creation of spoil mounds along the channels to discourage growth of cattail while supporting the growth of sedge-grass meadow species, re-creation of the barrier beach, and construction of new emergent marsh. We collected vegetation data for three years following the 2016 construction activities. Post-restoration results showed that cattail cover decreased greatly across years in the cattail treatment areas, decreased in lower elevation constructed habitats, and gradually increased in higher elevation habitats. Opening of the canopy resulted in increased floating and submersed species, and constructed mounds hosted wet meadow species. Site-level weighted mean C is recommended for future data analyses, rather than FQAI or mean C, because it has no observed influence from species richness. Restoration results were affected by high lake levels in 2017, identified problems in seeding and planting, and meeting construction plans for some channel and pothole depths and mound elevations. Pre-restoration soil surveys are recommended to reduce construction problems, and adaptive management should include invasive species control.

The potential applications of a virtual moving environment for assessing falls in elderly adultsThe purpose of this study was to investigate whether the moving room paradigm could be used to assess fall risk in older people. A group of young adults (18–29 years) and two groups of elderly adults (60–79 years) with and without a history of falls were placed into a simulated moving room. Participants stood still facing an oscillating three dimensional virtual room moving in the antero-posterior plane with three types of room movement conditions, continuous oscillatory, discrete anterior and discrete posterior. The young adults performed with less postural motion and coherence with the virtual motion than the older age groups. The group of elderly fallers exhibited more postural motion [center of pressure (COP) length, p < 0.05], a trend towards higher coherence with the object motion ( p = 0.07), and the greatest amount of time-to-stability ( p < 0.05). A virtual moving room incorporating measures of time-to-stability and egomotion appears useful in predicting risk for falls.

Dysfunctional career thoughts and attitudes as predictors of vocational identity among young adults with attention deficit hyperactivity disorderThis study examined dysfunctional career thoughts and attitudes as predictors of vocational identity among high school students with Attention Deficit Hyperactivity Disorder (ADHD). Regression analysis results indicated that dysfunctional career thoughts and attitudes were significant predictors of vocational identity, accounting for 42% of the explained variance. Dysfunctional career thinking, measured by the Career Thoughts Inventory (Sampson, Peterson, Lenz, Reardon, & Saunders, 1996) and the CareerMaturity Inventory—Revised (Crites & Savickas, 1996), displayed important predictive relationships with vocational identity as measured by the Vocational Identity Scale (Holland, Daiger, & Power, 1980). Implications for interventions and further research in vocational psychology and career counseling with ADHD students are discussed.
