Authors: Pote Sachin Eknath , Singal S.K. , Srivastava D.K.
Published: November 2024

Rivers are under increasing stress due to urbanization and other anthropogenic activities, leading to their over-exploitation and degradation. Godavari originates near Triambak in the Nasik district of Maharashtra, and flows through Madhya Pradesh, Karnataka, Orissa and Andhra Pradesh. Although its point of origin is just 80 km away from the Arabian Sea, it journeys 1465 km to fall into the Bay of Bengal. Like most other rivers, domestic pollution is the biggest polluter of the river Godavari, accounting for 82% of total pollution, whereas industrial pollution accounts for about 18%. The study covers 78 km of the river starting from the Kaigaon Toka to Shahagad. Six locations were selected for collection of water samples from the river and were analysed for water quality parameters in the environmental laboratory of Maharashtra Pollution Control Board (MPCB), Aurangabad. This data as well as the data from the Central Pollution Control Board were used to compute the National Sanitation, Foundation Water Quality Index (NSFWQI), which is generally applicable in USA and India. The results of the NSFWQI of Godavari River indicates its water quality as bad-medium over the stretch. Based on the results, the existing conservation measures have been reviewed and additional measures are suggested. The study concludes that major stress is industrial effluents and domestic pollution.

Published: November 2024

A simple analytical method was developed and optimised for the determination of polycyclic aromatic hydrocarbons in activated sludge consisting of supernatant and solid, which collected from the aerobic reactor (aerated zone) of the biological treatment step in a wastewater treatment plant. The procedure accomplishes in feasible time of extraction and reasonable solvent volume without the need of any special technique to perform the extraction step. The method involves extraction of entire sample by sonication and mechanical shaking using n-hexane, preconcentration by solvent evaporation, and determination by high-performance liquid chromatography with diode array and fluorescence detectors. The developed method was optimised to give precise results in both low and high spiked samples: relative standard deviation lower than 10%, limits of detection lied between 0.2 and 5 μg kg $^{-1}$ , and recoveries were between 66% and 109%. This method allows the monitoring of the bioremediation efficiency of PAHs by the activated sludge, since it permits the extraction of both PAHs; those that adsorbed to the solid phase, and the other that presented in supernatant phase. The activated sludge could be valuable in the bioremediation of lighter PAH compounds mainly those which consist of two and three fused aromatic rings.
Long-term Changes of Rainwater Quality in the Industrial Corridor	of Visakhapatnam, India
Authors: Yellapu Somu Naidu , Chandu Kavitha
Published: November 2024

The industrial expansion during the twenty-year period of 1983 to 2003 had shown its impact on rainwaters of Visakhapatnam. The ionic contents of SO $_4$ , NH $_4$ , NO $_3$ , Ca, Na and Cl along with pH and electrical conductivity are analysed for the rainwaters of Visakhapatnam industrial corridor during the period. The analysis shows that the atmospheric dust is more in summer rains than in the post-monsoon period, when the same had been washed down. However, unabated increase of air pollution over the two decades is indicated by the steady rise of conductivity of rainwater. The ratio between Ca $^+$ + NH $_4^+$ and NO $_3^-$ + SO $_4^-$ shows values consistently less than one, indicating the rise of acidic nature, in spite of the neutralization due to alkaline agents like Ca and NH $_4$ . Gradual decline of pH of rainwater forecasts an impending acidic rain in near-future.

Authors: Panda Swati , Patra A.K. , Mohanty S.K.
Published: November 2024

A study has been taken to evaluate the impact of industrial waste generated from different industries existing in Jagatpur Industrial Estate on river Mahanadi. Samples were collected from final discharge point to river Mahanadi of different industries as well as upstream and downstream of river Mahanadi to Jagatpur Industrial Estate. Samples were collected in three seasons. The results obtained at U/S and D/S points on river Mahanadi in different seasons (winter, summer and rainy) has been compared graphically. From the seasonal variation it was observed that almost all parameters are in increasing trend. In the rainy season, yearly average value at the D/S point is quite high as compared to yearly value at U/S point. The high values in rainy season is due to washing of waste dumping near Mahanadi bed. Quality Ratings for different parameters has been calculated from that water quality index was found out and compared. From the results it is concluded that, due to industrial waste discharge, water quality of river Mahanadi is deteriorated at the D/S point on river Mahanadi and the results are not meeting the prescribed standard for drinking water under Class A.

Published: November 2024

The copious prevalence of water deficiency and the geographical location of Iran (arid and semi-arid zone) make acquiring enough accurate data of water quantity and quality for water management vital. However, merely having sufficient data without proper interpretation is rather worthless too when it comes to effective water management and thus, there are several techniques for analyzing water quantity and quality. In this work, statistical method was used to analyze the data collected from the catchment area under study i.e. Jajrud River, located in the North West of Tehran Province. The multivariate time series method was employed to analyze water quality parameters in the river. Box-Jenkins time series model was also applied to the factor data resulted from the Multivariate time series. The results showed that the water quality parameters are not independent having a correlation coefficient larger than 0.3. The study also shows that ground water is the first effective factor, which causes increasing total dissolved solid (TDS) in the river. Domestic waste water pollution is the second-most important factor. Agricultural fertilizers and industrial waste may rank as the third and fourth pollution factors, respectively. Prediction of factor data using Box-Jenkins model was accurate and suitable which may be applicable to other place to model the factors data instead of many water quality parameters.
pH-based Alteration of Electrical Conductivity and Total Protein	Profile of Muscle of Fish, Heteropneustes fossilis (Bloch) as an Indicator of	Aquatic Pollution
Authors: Biswas Rana , Guha Bibhas
Published: November 2024

Alteration of electrical conductivity and total protein profiles of muscle of Heteropneustes fossilis (Bloch) have been assessed as an indicator of responses to change in pH of the aquatic medium. Fish were kept in different aquaria containing tap water maintained at different pH levels (viz., 3.0, 4.0, 5.0, 6.0, 7.0, 8.0, 9.0, 10.0 and 10.5) for 48 hrs and the muscle was exposed to different electrical fields by subjecting them to 5, 10, 15, 20 and 25 volt/cm. Required pH was accomplished by adding conc. HCl (AR grade) and NaOH (LR grade) in tap water. As protein is an organic semiconductor, the responses of electrical conductivity, protein band profiles (number, molecular weight and intensity of bands) and total protein content of muscle, if any, were analyzed at different pH to evaluate the extent of damage/alteration caused by pH at protein level. pH not only modulated the muscle conductivity at the lower and higher levels, but also altered significantly in regard to both protein profiles and total protein content, indicating possibility and relevance of utilizing pH as a potent indicator of extent of damage inflicted on fish muscle protein and thereby to a considerable extent the degree of aquatic pollution.

Published: November 2024

Time series analysis and forecasting has become an important tool in many applications in the field of air pollution and environmental management. ARIMA (Autoregressive Integrated Moving Average) models form an important part of the Box-Jenkins approach to time series data modelling. In this study Box-Jenkins method was used to construct ARIMA model for monthly particulate matter of air pollution data with a total of 108 readings from Dhaka meteorological station for the period 2002-2010. An attempt has been made to construct an ARIMA (0, 0, 2) (2, 1, 0) $_{12}$ model in a systematic and scientific manner. Based on the fitted ARIMA model, monthly particulate matter of air pollution for further two years has been predicted. It will help to make better decision for controlling air pollution in Dhaka city.

Authors: Ferdosi Yusuf Jamal , Chowdhury Al-Nakib , Hossain M. Mufazzal
Published: November 2024

Recently, mixed metal oxide (MMO) appears be a promising material for the removal of textile dyes. In our previous investigation with nickel-cobalt mixed oxide, anionic dye was removed (∼70%) by the matrix. In the extension of our study, copper-cobalt mixed oxide is studied to search for a superior adsorbent. Results demonstrated copper-cobalt mixed oxide as a better option to other oxide adsorbents.

A simple chemical route was followed to prepare MMO matrix by precipitating the corresponding metal carbonates and heating the mixture of carbonates at 650°C under ambient atmosphere. IR, SEM and XRD methods were used to inspect the prepared MMO, while composition was studied by EDX analysis. UV-Vis was carried out for the adsorption studies. An anionic dye and a cationic dye were used to study the oxide matrix as adsorbent. It has been shown that anionic dyes can be removed completely at low pH with the MMO matrix.

Authors: Singh Jagdish , Sharma Prashant
Published: November 2024

Bagasse is abundantly available agricultural crop waste obtained from renewable source, so it was used as raw material for ethanol production. Acid and heat pretreatment in combination with biological saccharificarion was evaluated for conversion of bagasse cellulose and hemicelluloses to fermentable sugars. Maximum yield of monomeric sugars (13.98 w/v) was achieved when acidic pretreatment in combination with heat was subsequently followed by enzymatic saccharificarion. The maximum ethanol production from S. cerevisae cells (1.6 × 10 $^9$ ) entrapped in sodium alginate beads of diameter 2.0-2.5 mm 14.0 g/L was achieved with ethanol productivity of 10 g L $^{-1}$ h $^{-1}$ and sugar utilization of 85% at dilution rate of 0.25 h $^{-1}$ by feeding 60 g/L glucose concentration in packed bed reactor at temperature 25°C and pH 5.5. This system for ethanol production was operationally stable for 136 h (cycle of 68 h).

Published: November 2024

The water quality assessment was conducted in Tiruchirappalli in southern India. The study region under consideration is located in the Indian southern state Tamilnadu, intersecting in the geological co-ordinates 10°48'9''N 78°42'43''E. It was doubted that the water resources in that location might be polluted due to the impact of distillery industry effluents located in the mentioned region thus causing stinky environment. So there was a necessity to test the ground and surface water pollutants. Clean plastic bottles were used to collect samples in various locations around the distillery unit. These samples were taken in three trials with fortnightly frequency. The collected samples were analyzed for their chemical parameters like hardness, pH, chlorides, sulphates, alkalinity, total dissolved solids, nickel, chromium, dissolved oxygen, biological oxygen demand and chemical oxygen demand. Surface water samples are analyzed for parameters like BOD, COD, TDS, copper, zinc, lead, cadmium, nickel and manganese. These parameters are helping to indicate the level of quality of ground and surface water for drinking and other domestic purposes. The parameters then were checked in par with the World Health Organization standards. As a result it is observed that some parameters such as hardness of ground water were 10 times as that of the pure drinking water with desirable limits.
Nitrogen Loading from Septic Tanks in the Coastal Plains
Authors: Rao Y.R. Satyaji , Keshari Ashok K. , Gosain Ashvani K.
Published: November 2024

The major non-agricultural source of nitrate in groundwater is septic-soak pit systems and unsewered conditions in the east coastal plains of India. This paper deals with the assessment of nitrogen loading from septic tanks in the Kakinada urban east coastal plains of Andhra Pradesh State, India. The proposed assessment methodology makes use of available databases of population, number of houses, sanitary information, soil types etc., in each village or sub-basins which are generally available in India or elsewhere. Two-dimensional Fuzzy c-Means clustering Technique (2 D FCM) was used to classify nitrogen load over the Kakinada urban coastal plain into low, medium and high zones. Further, these zones were validated with the respective average groundwater quality. The average groundwater nitrate and electrical conductivity values are following the patterns of nitrogen loading zones. Therefore, groundwater nitrate contamination is mainly due to the unsewered conditions and high density of septic systems in the study area. The methodology adopted in the present paper is useful for the assessment of nitrogen load from leaky septic systems in the coastal plains and also for prioritizing the villages or sub-basins for better management of non-agricultural sources of nitrate in coastal plains.

Published: November 2024

We assume that social and ecological systems are closely connected. Within the conceptual framework of Social-Ecological Systems (SES) analysis we focus on poverty, health and sustainable development within the Siak River catchment area in Riau Province (Sumatra). Substantial environmental changes in the last ten years, especially the degraded water quality of the Siak River, have directly affected the Siak ecosystem services and consequently the welfare and the livelihood of people who depend on these services. Impacts occur on income, health, job mobility and, to some degree, community culture for those who live in the Siak River basin. The income of fi sher families has been reduced signifi cantly forcing them to look for job alternatives elsewhere. The contaminated water has caused diseases that were not reported ten years ago.

Local village inhabitants, women specifi cally, are aware of the social-ecological nexus, i.e. the connection between river pollution and people's health in the riverside village communities. The economic disadvantages people experience from the degraded ecosystem services differ between villages but have severely lowered the standard of living and quality of life in riverside settlements.

Conclusions are drawn on the role of poverty, and the chances of alleviating health risks and pursuing sustainable development for the Siak river basin are explored.

Authors: Sendanayake S. , Miguntanna N.P. , Jayasinghe M.T.R.
Published: November 2024

Promotion of sustainable development in the building sector with reduced embodied energy and life cycle costs has become a primary need for facing the emerging threats of global warming and depleting energy sources. In this context, the minimization of the dependence on reticulated water supply is of crucial importance due to the high level of operational energy and the cost associated with the reticulated water supply. For this purpose, rainwater harvesting (RWH) can offer an ideal solution where the harvested water can be easily used for fl ushing of toilets and gardening. Though design curves and parameters are available for design of the rainwater tanks for a signifi cant water saving effi ciency (WSE) in temperate climate regions, the validity and the applicability of these curves and parameters for tropical climate regions such as Sri Lanka, where rainfall patterns vary signifi cantly across geographical and climatic boundaries, is still limited. It is also important to utilize a practical solution to develop multiple data, using short-term rainfall data, in order to compensate for the lack of available data for many geographical regions. In this research, a practical methodology was employed using short-term rainfall data and an experimental set up to validate design curves for WSE, obtained in temperate climate regions, to predict the WSE for tropical climate regions.

The concentration of heavy metals such as copper, iron, manganese, lead and zinc in top soil around a proposed uranium mining and tailings pond area in Nalgonda district, Andhra Pradesh, India was determined. Fourteen soil samples were collected in July 2010 and analysed as per standard procedures. The mean concentration of copper, iron, manganese, lead and zinc in the soil was 0.19, 54.48, 2.0, 0.33 and 0.34 mg/kg respectively. This study provided the spatial variation in concentration of heavy metals as a baseline data for impact assessments of the proposed uranium mining and tailings storage activity in future.
Fuzzy and Neuro-Fuzzy Modelling for Prediction of Effluent COD for	a Real Scale UASB Reactor Treating Distillery Wastewater
Authors: Varne Ashok L. , Macwan J.E.M.
Published: November 2024

The high rate anaerobic processes are used for treatment of industrial wastewater. These processes are subjected to many disturbances due to variation in quantity and quality of wastewater. Neuro-fuzzy (ANFIS) and fuzzy models were developed for prediction of effluent COD for an UASB reactor treating distillery wastewater. Different combinations of input parameters were assessed to obtain the ANFIS model. A fuzzy rule based model was developed with same combination of input parameters as ANFIS model. Expert's knowledge, plant operator's opinion and trend of the data were considered during model development. Parameters required for daily monitoring and operation of the plant were used for model development. Statistical parameters like the correlation coefficient (R) and root mean square error (RMSE) were used to assess the performance of these models. The value of 0.8922 and 1334.69 for R and RMSE were observed with the ANFIS model whereas 0.8197 and 4208.34 were obtained with the fuzzy model respectively. These values indicate good agreement between the predicted and observed values of effluent COD and satisfactory performance of the models. The modelling approach discussed in this paper will be useful for assessment of performance of the real scale UASB reactor and to control the operation of the plant.
Removal of Cadmium from a Sea-food Effluent Contaminated Soil by	Indigenous Biological Adsorbents Assessed with Soil Microbial Biomass
Authors: Bindu M.V. , Harikumar V.S.
Published: November 2024

Low-cost indigenous biological materials such as Dried Biomass of Azolla (DBA), Composted Coir Pith (CCP) and Dried Rice Husk (DRH) were tried as adsorbents for the removal of cadmium (Cd) from a sea-food effluent contaminated soil of south India. Soil incubation with indigenous biological materials significantly decreased the Cd concentration in contaminated soil as compared with non- incubated control. However, the concentration was far low in soils incubated with DBA followed by CCP. Furthermore, the Cd concentration of soil decreased with incubation time. Comparison of the Cd removal from soil revealed that the removal of Cd in treatment incubated with DBA and CCP was more or less on par. The kinetics of Cd adsorption followed the first-order rate expression given by Lagergren. Highest $k_{ad}$ value was noticed in treatment incubated with DBA followed by CCP. The present study revealed a significant inverse relationship between soil Cd concentration and soil microbial biomass carbon (SMBC). The SMBC significantly increased in treatments incubated with DBA and CCP.

Published: November 2024

In this paper, we describe the mechanistic details for arsenic mobilization in some newly formed char lands in Meghna basin, Bangladesh. We measured the concentrations of arsenic along with some other associated parameters involved in the release mechanism of arsenic in sediment-water interface. Total 38 water samples were collected and analyzed from both shallow (60 to 110 feet) and deep (⩾200 feet) aquifers and arsenic concentration ranged from 0 to 2.5 mg/L with an average value of 0.4266 mg/L. We observed three arsenic contaminated hot spots in the shallow aquifers where one spot's arsenic concentration is as high as 2.5 mg/L which could be the second highest arsenic contaminated spot in Bangladesh reported so far. Concentration of arsenic exhibits a clear positive correlation with iron and also with ammonium, bicarbonate and phosphate significantly. From the study, it reveals that reductive dissolution of arsenic-rich iron minerals is primarily responsible for the mobilization of arsenic in the groundwater. The presence of other competitive ions such as phosphate and bicarbonate in the adsorption-desorption process of arsenic were indentified for facilitating the mobilization.
Insomnia Prevalence and Mental Health Correlates Among 18,646 Users of an Internet-Based Cognitive-Behavioural Therapy Website: Archival Real-World Data from the United States, 2017–2019
Authors: Attridge Mark
Published: November 2024

Sleep problems were examined in archival data from 18,646 users of a commercial service that provided online health risk screening, educational resources, and self-guided computerized therapy lessons for insomnia and other mental health disorders. The sample was split between college students and working adults and represents a growing modern segment of adults who voluntarily seek out digital support for common behavioral issues. The goals were to explore the prevalence and possible correlates of insomnia among this unique sample. The cognitive behavioral-based therapy from this service has evidence of its clinical effectiveness and value to users in past research. Results revealed that 36% of all users were at risk for a clinical insomnia disorder. The severity of insomnia was significantly (all _p _<.001) associated with the severity of depression (_r_ =.65; 43% clinical); anxiety (_r_ =.54; 40% clinical); stress (_r_ =.54; 25% clinical); social phobia (_r_ =.34; 27% clinical); and general health status (_r_ = -.26; 15% clinical). Younger age was weakly associated with insomnia (_r_ = -.14; avg. 32 years; range 18-83), while both gender (_r_ = -.05; 76% female) and race (_r_ =.00; 81% White) were unrelated to insomnia. More severe insomnia was associated with lower work performance and greater work absenteeism (_r_ = -.30; _r_ =.17, respectively). The conclusions are that insomnia was commonly experienced among users of digital tools, often comorbid with other common mental health conditions, and linked to work performance problems. Thus, online self-help health and related digital services should screen for multiple disorders, including insomnia, rather than focusing on the specific disorder emphasized in the care program.
The Compton Wavelength Is the True Matter Wavelength, Linked to the Photon Wavelength, While the de Broglie Wavelength is Simply a Mathematical Derivative, Understanding this leads to Unification of Gravity and New Quantum Mechanics
Authors: Haug Prof. Espen Gaarder
Published: November 2024

We demonstrate that the Compton wavelength mathematically corresponds exactly to the photon wavelength of rest mass energy. On the other hand, the de Broglie wavelength is not defined for a rest-mass particle, but if the particle is nearly at rest, then the de Broglie wavelength approaches infinity, and the corresponding photon wavelength of the rest-mass energy is then this length times \(\frac{v}{c}\) again, that is it approaches zero when \(v\) approaches zero. Our analysis indicates that the de Broglie wavelength appears to be a pure mathematical derivative of the Compton wavelength. Everything that can be expressed with the de Broglie wavelength can essentially be expressed by the Compton wavelength. We also demonstrate how spectral lines from atoms and chemical elements are linked to the Compton wavelength of the electron and that the Rydberg constant is not needed.

Furthermore, we demonstrate that the Compton frequency is embedded in the Schrödinger equation, the Dirac equation, and the Klein-Gordon equation, where the Planck constant actually cancels out, and the de Broglie wavelength is not present in these equations. The Compton frequency seems to be linked to the quantization in quantum mechanics rather than the Planck constant. Additionally, we discuss recent literature that shows a remarkably simple but overlooked way to quantize Newton’s and General Relativity theories, as well as other gravity theories, and also how to link them to the Planck scale. This, once again, leads to the conclusion that the Compton wavelength and Compton frequency are related to the quantization of matter and, thereby, the quantization of gravity. In addition, the Planck length plays a crucial role in quantum gravity, as demonstrated.

Viewing physics through the de Broglie wavelength is like looking at the world through a distorted lens; switch to the Compton wavelength, and the distortion is removed, allowing us to see simplicity and clarity even in complex phenomena such as quantum gravity. Remarkably, Heisenberg’s uncertainty principle seems to need modification to a Certainty-Uncertainty Principle when one understands that the Compton wavelength is the true wavelength of matter. Gravity is related to the Planck mass particle and is again related to absolute rest, which lasts for the Planck time. This certainty-uncertainty principle leads to the unification of gravity and quantum mechanics.

The franciscana dolphin (_Pontoporia blainvillei_), a small cetacean native to the Southwestern Atlantic Ocean (SAO), is critically threatened by bycatch in gillnet fisheries and habitat degradation. The Franciscana Management Area (FMA) Ia, located in Espírito Santo, Brazil, harbors the most endangered population of small cetaceans in the SAO. The Doce River region represents a vital habitat for this species, particularly following the 2015 mining waste spill, which further disrupted local ecosystems. Through drone-based monitoring, this study investigates the diving and surface behavior of franciscana dolphins, providing valuable insights for refining population estimates and advancing conservation strategies. The average surface time was 17 seconds (±15s), and the average dive time was 64 seconds (±26s). The diving time was almost four times longer than the surface time. These findings underscore the importance of ongoing monitoring to support effective management of this vulnerable population.
Rosacea as a General Medical Problem: Pathogenesis, Clinical Picture, Principles of Management
Authors: Dmitriy S. Sukhanov , Yulia S. Alexeeva , Eugene V. Timofeev
Published: November 2024

Rosacea is a chronic inflammatory dermatosis characterized by facial skin lesions such as erythema, papules, pustules, phymas, and ocular involvement. In Russia, rosacea affects 5% of the population, while in European countries it ranges from 1.5% to 10%. This review presents the pathogenesis, classification, and modern approaches to the treatment of rosacea in Russia. Although rosacea is typically managed by specialists, it is also of interest to general practitioners. The goals of rosacea treatment are to reduce symptom severity and prevent disease exacerbations, thereby extending periods of stable remission. Despite advances in understanding the molecular mechanisms of the disease, development of classification approaches, and phenotype-­specific therapy, treatment failures and severe cases of rosacea persist. In addition to timely diagnosis and differential diagnosis in therapeutic practice, it is necessary to consider the increased risk of associations between rosacea and internal organ pathologies, as well as potential drug interactions among various medications used to treat this disease.

Studies show some biological properties associated with Dipteryx alata Vogel (Fabaceae), a typical species from Cerrado. Therefore, this work aimed to characterize the phytochemical compounds and analyze the antioxidant activity of the ethanolic extracts from the leaves and pulp of Baru. The leaves and fruits were collected randomly from ten individuals, in the city of Arinos (MG). The chemical compounds of the ethanolic extracts were analyzed by chemical reactions described in specific protocols. The content of phenolic compounds was quantified by spectrophotometry. Furthermore, the DPPH reduction method was used to verify the antioxidant activity. The results revealed a high antioxidant activity and a high content of phenolic compounds in Baru leaves, meanwhile in the pulp the values were lower. The obtained results with leaves and pulp extracts from Baru indicate a great antioxidant potential and additional studies should be performed to isolate the compounds, which are responsible for this activity in the plant.

Research on noun phrase use in EFL writing has mainly focused on linguistic complexity and accuracy, lexical richness, and phraseological competence. However, the relationship between noun lexical diversity of nouns and the syntactic complexity of the noun phrases in which these nouns appear remains underexplored. To address this gap, this paper examines the lexical diversity of head nouns in noun phrases within a sample of emails written by L1 Spanish EFL learners at B1 and C1 proficiency levels, taken from the FineDesc Learner Corpus. The analysis considers both the lexical diversity of nouns and the syntactic complexity of the noun phrases they head. The findings reveal: a) a narrower range of nouns at the B1 level compared to the C1 level; b) a low percentage of nouns from both levels, based on the English Vocabulary Profile; and c) differences in NP complexity between the two proficiency levels (B1 and C1), depending on whether the head nouns are concrete or abstract. The paper underscores the importance of combining different complexity measures ––namely, lexical diversity and NP complexity analyses–– to gain a more comprehensive understanding of learners’ use of noun phrases.

Дослідження полягало у вивченні торговельного та технологічного обладнання закладу торгівлі в якості важливої ланки формування атмосфери роздрібного торговельного підприємства. Підвищення рівня механізації та автоматизації торговельно-технологічних процесів, особливо важких і трудомістких фізичних робіт, пов’язаних із вантаженням і розвантаженням, переміщенням вантажів, є актуальним соціальним та економічним завданням у роздрібній торгівлі, вирішення якого можливе шляхом широкого застосування сучасної торговельної техніки, машин, устаткування. Зазначено: безпосередньо придбанню товару споживачем передує якийсь комунікаційний стимул, що включає контакт із певною інформацією, її опрацювання, виникнення позитивного комунікаційного ефекту. У результаті цього відбувається усвідомлення і формування потреби, додатковий пошук інформації, придбання товару і його споживання. У такій моделі дуже важливою є атмосфера в торговельному підприємстві, від якої багато в чому залежать остаточні дії споживачів продукції. Доведено, що важливими факторами привертання уваги і, як наслідок, сприяння зростанню кількості потенційних клієнтів, є зовнішній вигляд торговельного підприємства, його вивіски, світлове і колірне оформлення. Натомість рекламна функція торговельно-оперативного процесу багато в чому залежить від того, наскільки раціонально виконано викладення товарів, яке є важливим елементом торговельної реклами. Зроблено висновок, що розширенню контингенту постійних покупців, залученню нових клієнтів, зростанню товарообігу роздрібного торговельного підприємства багато в чому сприяють зусилля в галузі комунікаційної політики, яких докладає керівництво закладу торгівлі. При цьому перевага середовищного підходу у створенні в ньому відповідної атмосфери безсумнівна, оскільки саме його використання відповідає тим процесам у торговельному підприємництві, що затребувані в суспільстві інформаційного типу, коли естетичні форми фірмового стилю несуть інформацію про підприємство всім її цільовим аудиторіям – від співробітників роздрібного торговельного підприємства до широкої громадськості, коли фірмовий стиль працює комунікатором, як в управлінні, так і в комерційній діяльності закладу торгівлі.
The ALiEM Faculty Incubator: A Novel Online Approach to Faculty Development in Education Scholarship

Problem: Early- and midcareer clinician educators often lack a local discipline-specific community of practice (CoP) that encourages scholarly activity. As a result, these faculty members may feel disconnected from other scholars.

Approach: Academic Life in Emergency Medicine (ALiEM) piloted the Faculty Incubator. This longitudinal, asynchronous, online curriculum focused on developing a virtual CoP among 30 early- to midcareer medical educators (the "incubatees"), 8 core faculty mentors, and 10 guest mentors. The yearlong curriculum included 12 monthly modules focusing on core concepts in medical education scholarship. The initiative connected the incubatees with a virtual community of peers and mentors, with whom they completed multiple scholarly projects, sought mentorship, and engaged professionally. The authors used an online, closed, social media platform (Slack) to facilitate the exchange of ideas.

Outcomes: In the inaugural year (March 2016-February 2017), the mentorship team facilitated exceptional levels of online engagement among incubatees. All participants (incubatees, core mentors, and guest mentors) shared 1,081 files and exchanged a total of 22,665 messages (approximately 62 per day). Of these, 3,036 (13.4%) were via open channels, 5,483 (24.2%) via small groups, and 14,146 (62.4%) via direct messages.

Next steps: The ALiEM Faculty Incubator represents a proof of concept, and initial outcomes show that it is possible to engage an international group of early- to midcareer medical educators to create a vibrant online CoP. The Faculty Incubator leaders plan to determine whether this engaged group of health professions educators will increase their scholarly output as a result of this initiative.
The McMaster Modular Assessment Program (McMAP): A Theoretically Grounded Work-Based Assessment System for an Emergency Medicine Residency Program
Authors: Chan Teresa M. , Sherbino Jonathan , Collaborators McMAP
Published: November 2024

Problem: To assess resident competence, generalist programs such as emergency medicine (EM), which cover a broad content and skills base, require a substantial number of work-based assessments (WBAs) that integrate qualitative and quantitative data.

Approach: The McMaster Modular Assessment Program (McMAP), implemented in McMaster University's Royal College EM residency program in 2011-2012, is a programmatic assessment system that collects and aggregates data from 42 WBA instruments aligned with EM tasks and mapped to the CanMEDS competency framework. These instruments incorporate task-specific checklists, behaviorally anchored task-specific and global performance ratings, and written comments. They are completed by faculty following direct observation of residents during shifts. The rotation preceptor uses aggregated data to complete an end-of-rotation report for each resident in the form of a qualitative global assessment of performance.

Outcomes: The quality of end-of-rotation reports-as measured by comparing report quality one year prior to and one year after McMAP implementation using the Completed Clinical Evaluation Report Rating tool-has improved significantly (P < .001). This may be a result of basing McMAP's end-of-rotation reports on robust documentation of performance by multiple raters throughout a rotation rather than relying on a single faculty member's recall at rotation's end as in the previous system.

Next steps: By aligning theory-based assessment instruments with authentic EM work-based tasks, McMAP has changed the residency program's culture to normalize daily feedback. Next steps include determining how to handle "big data" in assessment and delineating policies for promotion decisions.
A guide to peer reviewing medical education scholarship: Advice from editors of AEM Education and Training
Authors: Gottlieb Michael , Chan Teresa M. , Promes Susan B.

[para. 1]: "Peer reviews in medical education can seem intimidating and the quality of reviews can vary widely. Many journals (including Academic Emergency Medicine Education and Training [AEM E&T]) provide scores for peer reviewers based on the quality of their reviews. While we share our reviewer scores each year, reviewers have asked how they could improve their reviewer scores and the strength of their reviews. As members of the editorial board for AEM E&T, we sought to share our insights and advice for creating a high-quality peer review of medical education research. To address this need, we identified some of the common reasons for lower scoring reviews and features of higher scoring reviews to guide reviewers in the spirit of education and continual improvement."
