    • Synthesis and Cytotoxicity Studies of Wood-Based Cationic Cellulose Nanocrystals as Potential Immunomodulators

      Imtiaz, Yusha; Tuga, Beza; Smith, Christopher W.; Rabideau, Alexander; Nguyen, Long; Liu, Yali; Hrapovic, Sabahudin; Ckless, Karina; Sunasee, Rajesh (MDPI AG, 2020-08-15)
      Polysaccharides have been shown to have immunomodulatory properties. Modulation of the immune system plays a crucial role in physiological processes as well as in the treatment and/or prevention of autoimmune and infectious diseases. Cellulose nanocrystals (CNCs) are derived from cellulose, the most abundant polysaccharide on the earth. CNCs are an emerging class of crystalline nanomaterials with exceptional physico-chemical properties for high-end applications and commercialization prospects. The aim of this study was to design, synthesize, and evaluate the cytotoxicity of a series of biocompatible, wood-based, cationic CNCs as potential immunomodulators. The anionic CNCs were rendered cationic by grafting with cationic polymers having pendant +NMe3 and +NH3 moieties. The success of the synthesis of the cationic CNCs was evidenced by Fourier transform infrared spectroscopy, dynamic light scattering, zeta potential, and elemental analysis. No modification in the nanocrystals rod-like shape was observed in transmission electron microscopy and atomic force microscopy analyses. Cytotoxicity studies using three different cell-based assays (MTT, Neutral Red, and LIVE/DEAD®) and three relevant mouse and human immune cells indicated very low cytotoxicity of the cationic CNCs in all tested experimental conditions. Overall, our results showed that cationic CNCs are suitable to be further investigated as immunomodulators and potential vaccine nanoadjuvants.
    • Addressing Misinformation on Whatsapp in India Through Intermediary Liability Policy, Platform Design Modification, and Media Literacy

      Medeiros, Ben; Singh, Pawan (Penn State University Press, 2020)
      Through a case study of lynchings in India that are perceived to have been catalyzed by misinformation on WhatsApp, this article explores how policymakers can mitigate social media misinformation without compromising public discourse. We evaluate the costs and benefits of three approaches to managing misinformation: intermediary liability reform, changes to platform design, and public information endeavors addressing user attitudes and behaviors. We find that while current media literacy endeavors seem somewhat misdirected, more locally attuned initiatives might productively address the underlying susceptibility to misinformation while avoiding the free speech compromises that come with stringent liability rules and restrictions on anonymous speech.
    • User-Generated Content and the Regulation of Reputational Harm: The Boston Marathon Bombing as Case Study

      Medeiros, Ben (2019)
      Calls for internet platforms to perform more proactive moderation of users' speech based on its topical content itself—whether voluntarily or under threat of legal liability—have proliferated in recent years. Using the reputationally-damaging instances of misidentification that occurred during the 2013 search for the Boston Marathon bombers as a case study, this article attempts to construct a more detailed, holistic picture of the mechanisms by which reputationally-problematic speech is negotiated online in the absence of sweeping changes to intermediary liability laws. The article argues that the Boston Marathon case study illustrates a blind spot in the more modest, targeted proposals to reform Section 230 of the Communications Decency Act in America that have appeared in recent years, and ultimately recommends placing additional emphasis on further developing norms of responsible speech in online communities, as their participants are perhaps more receptive to such endeavors than popular caricatures of "internet vigilantes" might suggest.
    • Picketing the Virtual Storefront: Content Moderation and Political Criticism of Businesses on Yelp

      Medeiros, Ben (2019)
      This article examines incidents in which business owners incur criticism on the consumer review platform Yelp based on political ideology. I analyze two case studies from the summer of 2018 by considering the sentiments expressed in the review texts, the application of Yelp’s relevant policies, and the tactical adaptations of reviewers. The case studies evince a normative conflict over how the platform should treat viral criticism of this sort. While Yelp clearly cannot truly function as a laissez-faire public forum, its moderation criteria can be gamed, and its efforts evidently exclude a range of sentiments that some users find meaningful. The article provides an in-depth exploration of a platform that has received somewhat less attention in the growing literature on the role of private intermediaries in shaping what kinds of speech attain visibility in the digital public sphere.
    • Inclusive schooling in Southeast Asian countries: a scoping review of the literature

      Hosshan, H.; Stancliffe, R. J.; Villeneuve, M.; Bonati, Michelle L. (Springer Science and Business Media LLC, 2019-07-29)
      Most of the Southeast Asian region is comprised of developing countries. This region has a short history of inclusive education implementation and differs from developed countries’ more mature inclusive education systems. This review reveals how inclusive schooling has been implemented in Southeast Asian countries and the current practices in the region. We used scoping review methodology to examine peer-reviewed literature published between January 1994 and January 2017 on inclusive schooling in the Southeast Asian countries. The inputs-processes-outcomes (IPO) model was used to group and describe the extant research. Thirty-eight articles were identified that contributed to region of Southeast Asia inclusive education research. The majority (n = 29, 76%) were published after 2010. The articles were organised by IPO stage: Inputs stage (staff professional and teacher education, resources and finances, leadership, curriculum and policy); Processes stage (collaboration and shared responsibility, school practice, classroom practice and climate) and Outcomes stage (participation). The elements of staff professional and teacher education, and collaboration and shared responsibility were most frequently featured in the literature of the inputs and processes stages. Research information about the outcomes stage of inclusive schooling was sparse. The inclusive education literature from the region is still emerging. A greater focus on outcomes is recommended in future research and practice. Having outcome data will enable evaluation of the quality and effectiveness of inclusive education. If evaluation reveals problems, then aspects of the inputs and processes stages may need to be improved to achieve better outcomes.
    • The Graph Theoretical Approach to Bankruptcy Prediction

      Choe, Kwangseek; Garas, Samy (2021)
      This paper examines the applicability of the graph theoretical approach to bankruptcy prediction. Various statistical techniques have been used to predict bankruptcy including univariate analysis, multivariate discrimination analysis, logit model, probit model, and neural networks. This paper employs the graph theoretical approach to bankruptcy prediction. The empirical findings confirms the validity of the proposed method for predicting bankruptcy. The proposed method in this paper provides an insight into the development of a new approach to the assessment of financial solvency of a company. This paper contributes to the literature by introducing a new approach to bankruptcy prediction.
    • Evidence on the Impact of Internal Control over Financial Reporting on Audit Fees

      Garas, Samy; Gaber, Mohamed; Lusk, Edward J. (2019-06-30)
      Introduction: Circa 1992, the dot.com sector created an irrational stock-trading market where the usual “financial” profiles of: Liquidity, Cash Flow from Operations, and Revenue Ggeneration were replaced by Ponzi-esque mayhem. To stabilize the markets, the Public Company Accounting Oversight Board [PCOAOB] required a second audit opinion: the COSO Opinion on the adequacy of management’s system of Internal Control over Financial Reporting: [ICoFR]. Study Focus: Three COSO-[ICoFR] designations are now required as public information: (i) A “clean” opinion [Is Effective], (ii) Deficiencies are noted, and (iii) Weaknesses reported. Our research interest is to determine, for a panel of randomly selected firms traded on the S&P500 for a eleventen-year period: 2005 to 2015, the nature of the effect that the COSO deficiency reporting protocol has on (i) Audit Fees and (ii) the Market Cap of traded firms. Method: To this end we collected, using the Audit Analytics [WRDS] database, various categories of reported Audit Fees and also Market Cap information. This random sample was classified into two sets: the first group: Is Effective SEC 302 Designation and No COSO issues & the second group: Is Not 100% Effective for which there were SEC 302 Deficiencies or Weaknesses noted. Results: Inferential testing indicates that failure to attend to the PCAOB-COSO imperatives results in a relational where there are higher Audit Fees and a slippage of the firm’s Market Cap compared to the Is Effective Group. The PCAOB’s protocol to require the Audit of the firm’s ICoFR system and make that evaluation public information seems to be an excellent corrective “Carrot and Stick”.
    • Examining Preservice Teacher Attitudes and Efficacy about Inclusive Education

      Puliatte, Alison; Martin, Melissa; Bostedor, Emily (2021)
      The purpose of this study was to examine pre-service teacher self-efficacy and attitudes towards inclusion. Participants included pre-service teachers (N = 68) who were all enrolled in a freshman education course. Researchers administered two scales including the Teacher Efficacy for Inclusive Practices scale (TEIP; Sharma, Loreman & Forlin, 2012) and Scale of Teacher’s Attitudes towards Inclusive Classrooms (STATIC; Cochran, 1997). Results indicate preservice teachers have high self-efficacy and positive attitudes towards teaching students with disabilities.
    • Post Outbreak Gypsy Moth (Lymantria dispar) Egg Mass Survey in Northern New York

      Imm, Kaila; Garneau, Danielle (2021-05)
      Gypsy moths (Lymantria dispar) are an invasive species whose initial spread centered in Massachusetts and quickly advanced throughout the Northeast before reaching the mid-Atlantic, Michigan, and Wisconsin. These large-scale defoliators serve as a cyclical wave of disturbance with varying annual intensity and periodic peak years. Gypsy moth management is stage-specific, so understanding the life cycle is essential in order to facilitate the best management practices. In spring 2021, I surveyed gypsy moth egg mass densities in forested areas within Clinton and Essex County New York to determine if pest outbreak thresholds were met in the region. Across nine sites, which included local landowner properties, state parks, and wildlife management areas, I followed the NYS DEC egg mass sampling protocol. At each site, four plots were established and metrics collected included tree species, tree diameter, bark texture, and egg mass abundance and vertical distribution. Threshold infestation levels were met in five of the nine sites and Wickham Marsh forest was the most heavily infested. The most impacted trees were eastern white pine (Pinus strobus) and northern red oak (Quercus rubrum), specifically those individuals with an average diameter of 44.7 cm and vertically cracked bark. The data collected in this survey will inform regional biologists of more heavily damaged forests and land owners in order for them to develop a management plan for gypsy moths in the North Country.
    • "Alexa, Alert Me When the Revolution Comes": Gender, Affect, and Labor in the Age of Home-Based Artificial Intelligence

      Schiller, Amy; McMahon, John (2019)
      The fantasy of automation is one of liberation from alienating tasks. Today, domestic artificial intelligence (AI) enacts this dream of frictionlessly offloading monotony. This article deploys theories of Marxist feminism, affective labor to interrogate domestic AI’s unprecedented promise of absorbing forms of labor we hardly acknowledged that we did. While these devices make the reproductive labor of the household legible as labor, we interrogate their quasi-emancipatory promise. We argue that devices such as Amazon’s Alexa or Google Home elide and reproduce the gendered and racialized dimensions of domestic labor, streamline this labor for capture by capital, and heighten the very affective dynamics they promise to ameliorate. Only critical political theories of work can illuminate the unfulfilled transformations and ongoing dominations of gender, race, and affect that saturate labor with domestic AI – expressed, we contend, by re-articulating the framework of the “social factory” to that of the “social server.”
    • Producing Political Knowledge: Students as Podcasters in the Political Science Classroom

      McMahon, John (Journal of Political Science Education, 2019)
      Given the increasing prevalence of podcast listening, especially among young adults with college education, it is important to consider how student-produced podcasts can impact the student experience in the classroom, contribute to a more participatory course, and help achieve learning objectives. To engage these issues, this article reflects on the podcast assignment completed by five courses of students, three introductory American Politics classes and two Political Ideologies classes. This article seeks to examine how podcasts can work as a tool for students to research, analyze, synthesize, and present political information in a specific pedagogical and rhetorical setting; in the course of doing so, students become actively engaged with the audio public political sphere. I focus on assignment design, learning objectives, and my own pedagogical reflections in order to reach some tentative ideas about the pedagogical potential of podcasts in the political science classroom.
    • Rosa Luxemburg and the Primitive Accumulation of Whiteness

      McMahon, John; Issar, Siddhant; Brown, Rachel H. (Rowman & Littlefield Publishers, 2021)
      One of Rosa Luxemburg’s signal contributions to the critique of capitalism is her theorization of primitive accumulation as an ongoing imperial practice that is endemic to capitalism, rather than a historical phase belonging to capital’s pre-history. This dimension of her thought marks a turning point for theorizing capital’s violence. Indeed, a variety of contemporary thinkers have since built upon Luxemburg’s insights to interrogate the continuity of primitive accumulation in the present. Our paper extends Luxemburg’s distinctive intervention beyond its current application by interweaving her work on primitive accumulation with analyses of racial capitalism, the logic of global coloniality, and race-making in medieval Europe. We begin by examining how racial hierarchy and the historical production of whiteness complicate, supplement, and are bound up with Luxemburg’s prescient analysis of primitive accumulation. We then analyze several (re)constitutions of whiteness to conceptualize how they mediate and enable racial capitalism, from the European Middle Ages to our contemporary moment of neoliberal imperialism. Ultimately, we claim that creolizing Luxemburg enables the theorization of the primitive accumulation of whiteness, a concept that elucidates a dynamic by which racial capitalism operates. This concept highlights how processes of racialization, particularly the consolidation of whiteness as a racial-civilizational category, are necessary to ongoing imperial accumulations of capital; situates Luxemburg as a theorist of racial capitalism; and ensures that accounts of early modalities of whiteness in medieval race-making and later in neoliberal modes of imperialism do not understand whiteness or race as phenomena separate from capital.
    • Small Mammal Community Response to Wildfire at the Altona Flat Rock Sandstone Pavement Barren

      Garneau, Danielle; Hendrick, Michala; Darienzo, Lauren; Farr, Emily; Epifaino, Alex; Garneau, Danielle (2021-03-17)
      The Altona Flat Rock is a sandstone pavement barren, dominated by the fire-dependent species known as Pinus banksiana (Jack Pine). Changes in seed availability, understory structure, and predator presence influence wildlife migration within the barren. Additionally, small mammal abundance often fluctuates cyclical in response to tree masting. In July 2018, a wildfire occurred at the Flat Rock pine barren. We aimed to monitor small mammal response to wildfire over the course of a year. Small mammal traps were set along established transects capturing the fire severity gradient and adjacent reference unburned area. Along those same transects, giving up density surveys (GUDS) were performed to foraging patterns in these varied microhabitats. We predicted greater capture rates and community diversity in the burn immediately post-fire due to access to the abundant serotinous Jack Pine seeds. In fall 2018 immediately following the wildfire, a total of 67 small mammals were captured with 1.5 times more in the unburned than burned area. The small mammal community consisted of Peromyscus spp. comprising 87% of captures and insectivores Sorex cinereus (Masked Shrew) and Blarina brevicauda (Northern Short-tailed Shrew) were absent from the burn. In fall of 2019, a total of 21 small mammals were captured with 3 times more in the burn than in unburned area. Community composition was exclusively Peromyscus spp. Over the course of a year, we noted a significant reduction in captures and a shift in microhabitat usage from unburned (2018) to burn (2019) likely in response to regenerating vegetation ameliorating predation risk. Interestingly, average body mass and total body length were higher in Peromyscus spp. in 2019, perhaps in response to increased seed predation. GUD survey results show seed foraging was 67% greater in 2018. Collaborators monitoring game cameras at the barren noted increased predator use of the unburned and burned areas in winter 2018 and spring 2019, respectively and a significant decline of predators from the area in late summer-fall 2019. A predator decrease in fall 2019 is paralleled with a significant decline in Peromyscus spp. This preliminary research has revealed the complexity of small mammal response to wildfire. Long-term monitoring will likely uncover their connection to resources, microhabitat structure, and predator abundance as regeneration continues.

    • Non-invasive Monitoring of Nest Boxes

      Johnson, Kaylee; Garneau, Danielle (2020-05-05)
      Nest boxes are an important wildlife management tool which have proven successful in long-term recoveries of waterfowl and other species. Previous studies have shown that flying sqquirrels (Glaucomys sabrinus and G. volans) communally nest in these boxes in northern New York. We sought to monitor wildlife occupancy in nest boxes using non-invasive technologies including cameras and acoustic devices. Between 2019-2020, nest boxes were monitored at the recently burned Altona Flat Rock Forest in northern New York. GoPro cameras were mounted to telescoping poles to check nest boxes for occupancy and other wildlife sign. Later in the survey, goPros were mounted to the boxes for overnight visual and acoustic sampling. Concurrent acoustic sampling was performed using a smartphone enabled bat detector (Echo Meter Touch 2), as studies have shown flying squirrel vocalizations fall in the detectable range of many bat species. Monitoring revealed sign of wildlife (e.g., nests, debris, scat) in nest boxes erected in the burn site. In addition, acoustic data confirmed the presence of a species of concern in our region, the eastern whip-poor-will (Caprimulgus vociferus) who are known to have strict habitat needs involving open forests and a dense understory to protect nests from predators. This research has offered a window into the potential success wildlife professionals might have using alternative survey methods (e.g., technology) when monitoring sensitive species.
    • Examining the Presence of Microplastic in Wastewater-Derived Soil Amendment

      Koritkowski, Carlee; Garneau, Danielle (2020-05-05)
      There is growing research on the impact of microplastics in terms of uptake in consumer products (e.g., sea salt, bottled/tap water, beer, mussels, fish, and soil amendments). Studies have shown that wastewater effluent and biosolids are potential pathways for microplastics to enter marine, freshwater, and terrestrial environments. Some soil amendments derive from the bacterial mats associated with wastewater processing and are potential pathways of microplastics via soil runoff into surrounding waterbodies. The presence of microplastics in these ecosystems impacts food webs at varying trophic levels and contributes to the persistence of microplastics in the environment. We examined a wastewater-derived soil amendment for microplastics using standard characterization methods. Quantification of microplastics following distilled water hydration of 82g of soil amendment yielded 69 particles. These particulate were primarily fibers (69%) and foams (19%), with lesser films (4%), beads (4%), and fragments (3%). The majority were smaller (125-355um) fiber particles. A standard bag of this soil amendment is 14515g with coverage of 232m2. The average-sized lawn in the United States is approximately 911m2, resulting in the potential to contribute 330,240 particles into soil and ultimately adjacent waterways. Next steps have begun to streamline this process by adopting the wet peroxide oxidation digestion method in an attempt to reduce organic matter. Nile red staining is a recently introduced method that effectively binds to plastic and is visualized using ultraviolet light. Microplastic researchers have developed automated (MP-VAT) software to streamline microplastic quantification and characterization in conjunction with Nile red staining procedures. We aim to incorporate this new approach and evaluate best practices in microplastic quantification and characterization of wastewater-derived soil amendments, as their potential ecosystem consequences are broad. It is important to continue elucidating pathways of these emerging persistent pollutants.
    • Camera trap monitoring of wildlife following a wildfire at the Altona Flat Rock forest

      Jaeger, Tristan; Adams, Matthew; Staats, Lloyd; Garneau, Danielle; Lesser, Mark (2020-05-05)
      Forest disturbance can drastically alter wildlife habitat (i.e., cover, forage and prey abundance). Response of wildlife to disturbance events, particularly the timing involved in returning to pre-disturbance conditions, are important aspects of overall ecosystem recovery and resilience. Here, we study wildlife occurrence and usage patterns following a disturbance at a sandstone pavement pine barren in northern NY. This site is dominated by Pinus banksiana (Jack Pine) with an understory largely comprised of Vaccinium angustifolium (Low-bush Blueberry) and Gaylussacia baccata (Huckleberry) serving as a major wildlife resource and fuel for this fire-dependent system. In July 2018, ~220ha of this forest was burned in a wildfire. In fall 2018, eight game cameras were installed along transects traversing a gradient of burn severity as well as an adjacent unburned reference area. Annual and seasonal abundances, and diel wildlife activity were characterized using the camTrap package in R Studio. Over the course of the study, overall species richness in the unburned and burned areas were differed (n= 15 and n= 13 respectively), though total occurrences were higher in the unburned (n = 361) than in the burned area (n = 480). Common species captured on the barren include Odocoileus virginianus (White-tailed Deer), Lepus americanus (Snowshoe Hare), and Tamiasciurus hudsonicus (Red Squirrel) which more prevalent in the unburned, while Canis latrans (Coyote) were more common in the burned area. Seasonal trends in wildlife abundance show a clear benefit to being in the unburned area in fall through winter 2018 as it provides resources and hiding cover. In spring, wildlife increased activity within the regenerating burn which remained in high use until summer-fall 2019. Interestingly, Coyote’s use of burned and unburned areas tracks that of their Snowshoe Hare prey and is most pronounced in the burn during spring. At the barren, Snowshoe Hare and Coyote behave nocturnally as compared the diurnal activity of White-tailed Deer. In the unburned area, Coyote appear to shift activity to capture the morning peak of Deer. Further long-term monitoring will elucidate how wildfire affects wildlife community composition, abundance, and distribution on the Altona Flat Rock sandstone pavement barren.
    • Impacts on the growth of Sweet Corn (Zea Mays) exposed to plastic weed fabric and soil amendment with and without earthworms

      Lee, Linh; Gomez, Isabel; Garneau, Danielle (2020-05-05)
      Agricultural practices, such as farm field application of sewer sludge or use of plastic weed fabrics may impact yield of crop plants. Numerous studies have documented the presence of microplastics in wastewater treatment plant effluent and sludge and have noted negative impacts on terrestrial and aquatic organisms. Plastic mulch and weed fabrics are increasingly more common in small-scale farming and over time will degrade into finer microplastic particulate. Both plastic sources have the potential to leach residues into soils and adjacent waterbodies, with potential impacts on both plants and wildlife. Earthworm bioturbation has the potential to redistribute microplastics even deeper into the soils as they consume and lay castings. We established a greenhouse experiment to examine the effects of farming-associated plastics on Sweet Corn (Zea mays) in the presence of Red Worms (Eisenia foetida). We sowed 4 corn seeds per pot across 5 treatments (control, macroplastic, microplastic, amendment 1mm, amendment 355um) with 6 replicates per treatment and lined and covered the pots with screening. Once plants were established (13 days), two Red Worms were introduced to three pots across all treatments. Plant height was measured weekly and upon harvest, stem diameter, leaf abundance, and weights were obtained. Preliminary results suggest that the amendment hastened the date of first germination (6 days post-planting). All plants germinated in 1mm amendment and macroplastic, whereas minimum (88%) germination was observed in 355um amendment and microplastic treatments. There was a statistical difference in the height of Sweet Corn after a week with the tallest plants deriving from the 1mm amendment treatment (p = 0.037, F = 2.643, df = 119). This study serves to help elucidate the complex interactions of microplastic and soil-dwelling organisms on yield of crop plants. Our results will inform farmers and land managers about avoiding techniques that will potentially increase plastics inputs into ecosystems.
