“…[28]; which were significantly lower than our data; therefore it is important to report and publish updated phosphate level in the Harlem River. Total P (TP) and organic P (OP) was tested on limited water samples collected in 2011; the TP maximum was 3.115 mg/L during April 28 heavy thunderstorm at CSO discharge point site 3, followed by 0.624 on March 17 at site 2, and 0.581 at site 4 on May 5; average TP was 0.531 mg/L which was higher than average TP in the Bronx River (0.438 mg/L in 2006 and 0.089 mg/L in 2007) [46] [47]. Organic P average was 0.428 mg/L, which was higher than average OP in the Bronx River as well (0.372 mg/L in 2006; 0.021 mg/L in 2007) [46] [47]; OP maximum was 2.919 mg/L during heavy thunderstorm on April 28 2011.…”

The Harlem River, a 9.3-mile channel that flows from the Hudson River to the East River, has experienced decades of industrial abuse and remains gritty and industrial. During heavy rains, the pipes discharge raw sewage into the river through combined sewer overflows (CSOs) that can contain bacteria and cause illness. Water samples were collected from CSO discharge point and several adjacent sites along the river in the Bronx side close to River Park Towers at Richman Plaza and Manhattan side at Wards Island. Nutrients, bacteria, polychlorinated biphenyls (PCBs), and fish consumption safety have been analyzed. Results showed that phosphorus, ammonia concentration as well as fecal coliform, E.Coli, enterococcus levels increased significantly during heavy rainstorms. Ammonia concentration was up to 2.725 mg/L during tropical storm Arthur on C 12 H 8 C l2 ), the high molecular weight (MW), an indicator of raw sewer and storm water runoff in the NYC harbor waters, is the major polychlorinated biphenyls (PCBs) in the Harlem River. PCBs are carcinogenic, which could bioaccumulate via food chain from fish and seafood, endangering public health. Oyster farming has been used to purify water and improve water quality in the river. CSOs and storm water runoff have degraded water quality and been threatening environmental ecosystem and public health. This research will help local communities understand CSO impact on nutrients, bacteria, PCBs contamination and fish consumption safety, and make contributions on CSOs reduction as well as improve water quality and environmental ecosystem in the Harlem River.

“…These water bodies are characterized by a long time turnover, which causes a degenerative state of water quality. This phenomenon therefore affects equally the seas, rivers and lakes that present these conditions everywhere in the World (Recanatesi, Ripa, Leone, Perini, & Salvati, 2013;Wang & Pant, 2011).…”

Due to the concomitance of several factors related to progressive climate changes and to increased water management for anthropogenic usage, drastic fall in level of Bracciano Lake, a volcanic lake, 30 km northwest of Rome, was reported. In November 2017 the water level decreased 1.98 m below the hydrometric zero. Vulnerability to eutrophication was investigated by determination of the lake water volume and the related phosphorus concentration. At this purpose, the bathymetry layer of the water body and the application of supervised classification of Sentinel-2 images allowed to quantify the water body and to define the coastline shape. Once calculated the hydrometric reduction in water body after the hydrometric crisis, occurred in 2017, Vollenweider model allowed to estimate nutrient concentration (around 100.93 µg/l) and the relative increase of the eutrophication status (+2.3% per liter). According to the lake water quality classification proposed by the OECD, we classified the lake as a very eutrophic lake with a hypertrophic level in the period of water crisis. The proposed methodology represents an efficient monitoring tool for assessing the vulnerability of water bodies influenced by eutrophication. ARTICLE HISTORY

“…The concept of mindset (MS), or implicit theories, dates back to Kelly's (1955) work, which presented some lay theories of the way people perceive the self and others. Recently, in the area of education, more concepts have been engendered via the construct of MS, in which the assumptions and beliefs of certain human traits have largely been connected to Carol Dweck and her associates' works (e.g., Blackwell, Trzesniewski, & Dweck, 2007;Chiu, Hong, & Dweck, 1997;Dweck, 2006;Dweck & Molden, 2007;Dweck, Chiu, & Hong, 1995;Hong, Chiu, & Dweck, 1999). Additionally, mindsets have a close association with a number of theoretical and empirical studies on second language learning (e.g., Barcelos, 2003;Benson & Lor, 1999;Cotterall, 1999;Horwitz, 1998;White, 2008) where the relationships between mindsets and language-learning behavior have been investigated.…”

The present study intended to investigate intermediate Iranian EFL learners’ language mindsets and examine the possible relationships between language mindsets and feedback preferences in L2 writing. To achieve these aims, 150 EFL volunteer learners were recruited from several language institutes in Isfahan, Iran, and their language proficiency level was determined through a proficiency test. The learners were then given the Language Mindsets Questionnaire and the Feedback Preferences Scale to fill out. Frequency counts, mean scores, one-sample t-tests, and SEM in Smart PLS were employed to analyze the collected data. The results of the study indicated that for the three subcomponents of the mindsets questionnaire (i.e., general language intelligence beliefs, second language aptitude beliefs, and age sensitivity beliefs about language learning), the learners did not agree (though not significantly) with the entity items, while they expressed significant agreement with the incremental items. The SEM results also revealed that the model (examining the relationship between entity/incremental mindsets and feedback preferences) indicated that entity mindsets were a significant predictor of feedback preferences, yet the incremental mindsets failed to do so. Among the feedback types, EFL learners’ preferences, in a deductive order, were found to be for commentary and conferencing significantly, and then for peer correction, prompts, self-correction to a non-significant extent. The significance of the obtained results are presented and the implications of the study are enumerated.
