Anatase TiO2 surfaces have been treated with 2, 4, 6-triphenylpyrylium hydrogen sulfate (TPPHS) or tripyridylporhpyrinatomanganese(II) (MnP) dyes to yield the modified TiO2/ dye surfaces. The modified TiO2/dye surface was then supported onto activated carbon (AC) surfaces to yield a new class of catalytic system AC/TiO2/dye. The catalytic activities of naked TiO2, dye solution, TiO2/dye, and AC/TiO2/dye systems were examined in photo-degradation of Methamidophos (insecticide) in water, using both UV and visible light. All examined systems showed catalytic activity when used either in the UV or the visible regions, but the AC/TiO2/ dye showed the highest activity. The dye role, in …

Monetized Competitive Peer-To-Peer Skill-Based Game Play–An Introduction, Becky Harris, Bill Coley, Peter Gan, Anh-Vu Nguyen

International Gaming Institute Faculty Research

The COVID pandemic has changed the world in ways, both large and small, forever. One unexpected way the world changed was when live sports suddenly went dark and esports began experiencing attention from betting audiences that were suddenly starving for content.¹ Esports also received a second glance from gaming regulators. And, though not exactly suddenly (even though it felt like it), approvals for wagering on esports were granted in a variety of jurisdictions, most notably Colorado and Nevada.²

A subset of the larger esports environment, peer-to-peer (P2P) skill-based play is hardly a new concept. You can find it …

Guess Who Is Not Using Mobile Money In Sub-Saharan Africa?, Aparna Gosavi

Southern University College of Business E-Journal

Mobile money, which is a mobile-phone-based service, sends and/or receives money across a wide geographical area with just a touch of a mobile-phone button. This particular financial product was initially introduced in Kenya in the early part of 2007. Within the first six months of its introduction in Kenya, more than two million people enrolled for the service, partly because the utility emerged as a handy tool for urban migrants to send money back home to their families who resided in villages. This overwhelming response to the service was mainly because of its convenience, safety, and speed. Now, in Sub-Saharan …

Southern University College of Business E-Journal

The economic consequences of a First Nations response to Enbridge and the voicing of concerns over the violation of human rights resulting from the proposed Northern Gateway pipeline are examined. Despite overwhelming opposition and contrary to indigenous rights, the proposed pipeline was to cross more than 50 territories claimed by First Nations. The pipeline would transverse through unique ecosystems that are home to endangered species, and tankers would travel through one of the largest undeveloped temperate rainforests in the world. Given Enbridge’s history with oil spills and environmental violations, potential future oil spills are a serious concern. Because of these …

Impairment Recognition And Revaluation– China Publicly Listed Companies, Ying Wang

Southern University College of Business E-Journal

The advent of SFAS 142 and IAS 36 regarding handling of asset impairment has spawned research into how these standards influence whether an impairment loss is recorded. Deferred tax items in China have three major components: temporary tax and financial reporting differences in depreciation; impairment losses; and previous losses, which can be carried forward for five years for tax purposes. While the temporary differences in depreciation typically defer taxes and create deferred tax liabilities, impairment losses and previous losses create deferred tax assets because they are not deductible in the current period for tax purposes. A deferred tax asset is …
