Seagrass meadows are natural carbon sinks, yet the effect of ocean acidification on their carbon burial capacity remains poorly understood. Here we investigated natural carbon dioxide vents in Ischia, Italy to assess how seawater pH influences carbon burial in an area dominated by the seagrass Posidonia oceanica. Organic carbon burial rates (mean ± standard error) between 1954 – 2021 were low under ambient conditions (1.5 ± 0.5 g m-2 yr-1) but increased sharply under acidified conditions (7 ± 1 g m-2 yr-1), reaching sevenfold higher values under extreme acidification (10 ± 3 g m-2 yr-1). Stable isotopes suggest that these …


Horizontal Regulatory Barriers In International Trade: Evidence From Electric Plugs, Yuan Mei, Mingzhi (Jimmy) Xu Dec 2026

Horizontal Regulatory Barriers In International Trade: Evidence From Electric Plugs, Yuan Mei, Mingzhi (Jimmy) Xu

Research Collection School Of Economics

Domestic policies regulating the horizontal dimensions of product differentiation can impede international trade and have become a major concern in contemporary trade negotiations. We estimate trade frictions associated with incompatible designs of electric plugs, a well-known example of a horizontal regulatory barrier. Our findings indicate that fewer electronic devices are exported to destinations with incompatible electric plugs, and this effect operates through both the extensive margin and the intensive margin of exports. These results are further corroborated by an online survey of Chinese electronics exporters. Moreover, incompatible plugs are associated with lower average quality of exported electronic devices, suggesting that …

The Effects Of Eps Level And Presentation Format Of Analysts’ Forecast Deviation On Non-Professional Investors’ Investment Judgments, Clarence Goh, Prasart Jongjaroenkamol, Poh-Sun Seow

Research Collection School Of Accountancy

We experimentally investigate how the presentation format of the extent to which a firm's earnings per share (EPS) diverges from analysts' EPS forecasts (i.e. deviation information) and a firm's EPS level affect the investment judgments of non-professional investors (referred to hereafter as “investors”). Our results suggest that investors' investment judgments are more positive when firms with low (high) EPS levels disclose deviation information in percentage (absolute) terms. Furthermore, when the percentage of forecast deviation is held constant, investment judgments are more positive when EPS levels are high versus low if the deviation information is expressed in absolute terms. By contrast, …

Do Flywheel Exercises Provide Eccentric-Overload Training?, Darjan Spudić, Kazunori Nosaka Dec 2026

Do Flywheel Exercises Provide Eccentric-Overload Training?, Darjan Spudić, Kazunori Nosaka

Research outputs 2022 to 2026

Interests in eccentric resistance exercises have been increasing in both research and practice. However, implementing eccentric resistance exercise training is often challenging due to the mechanical limitations of traditional training equipment. To address this, flywheel (FW) devices emerged as a practical alternative. FW devices are commonly considered to provide eccentric-overload training, in which the load is greater in eccentric than concentric phase. However, this is not always the case. In this article, we summarize the mechanical and physiological factors influencing the effectiveness of FW devices in achieving eccentric overload. Then, we discuss a significant limitation of FW resistance exercise in …

Accurate species identification from Whole Genome Sequencing (WGS) data remains challenging, particularly for closely related species such as sheep (Ovis aries) and goats (Capra hircus). Through analysis of mapping quality metrics and Kraken2 taxonomic classification of 40 WGS sheep and goat samples, we demonstrate that conventional approaches yield ambiguous results, with overlapping alignment rates and inconclusive taxonomic assignments. We present a robust comparative genomic approach that uses species-specific genomic regions to distinguish these species in WGS samples. We define species-specific regions as those exhibiting distinctive coverage patterns: average coverage when samples are aligned to their matching reference genome but absent/low …
