Cessationism and continuationism: Pentecostal trinitarianism balances the tension
Authors: Resane Kelebogile T.
Published: November 2022

There are three streams of theological thoughts on charismata. The first thought is the cessationists who believe that all sign gifts were designed for canonical conclusion, and therefore ceased when canon was completed. This theological stance was endorsed by Reformers such as Calvin and some Catholics. Later, around the 17th century to date, this stance had been challenged by evidence of these spiritual gifts in operation. There are four mainstream cessationists. Firstly, full cessationists are totally anti-miracles. Secondly, concentric cessationists believe in the total cessation of charismata and miracles in mainline Christianity and evangelised territories. However, miracles may manifest in unevangelised areas as an aid to the missional endeavors. Thirdly, classical cessationists of whom the charismatic manifestations served as the launching pads for evangelisation and the affirmation of God’s revelation. Finally, consistent cessationists go further to declare that although the miraculous gifts were for church establishment in the 1st century, the apostles and prophets also ceased. The second thought is continuationism, which stands in juxtaposition with the cessationists. They are convinced that charismata never ceased. If they cease, it will be at the return of Christ. Pentecostalism, through its trinitarianism, stands in the middle of the two thoughts and enhances the continuationist stance. It is a movement that accepts the holistic or trinitarian view of God. The God of the Old Testament continues to be the God of the New Testament up to current times. Its trinitarian emphasis puts it above the cessationist-continuationist tensions.Intradisciplinary and/or interdisciplinary implications: The article’s intradisciplinary implication was realised through the appeal to numerous theological disciplines such as biblical studies, church history, ecclesiology and pneumatology. These various disciplines and doctrines argue that although cessationism and continuationism are common in theological thoughts today, Pentecostal trinitarianism is growing and gaining more ground at the grassroots levels.
Comparative Evaluation of Penetrative and Adaptive Properties of Unfilled and Filled Resin-Based Sealants When Placed using Conventional acid Etching, Lasing, and Fissurotomy Bur Technique of Enamel Preparation
Authors: Shingare Poonam Ramrao , Chaugule Vishwas , Pankey Neha , Kakade Pallavi
Published: November 2022

Background:

There is a confusion regarding selection of unfilled or filled sealant and method of enamel preparation before sealant application. This study was carried out to compare three techniques of enamel preparation using both unfilled and filled type of sealants.

Objective:

The objective of the study is to assess the penetrative and adaptive ability of filled and unfilled sealants in three techniques of enamel fissure preparations.

Materials and Methods:

Total 36 extracted teeth were divided into 3 groups, each containing 12 samples. The samples of Group A were prepared by conventional acid etching with 37% phosphoric acid, and the Group B was subjected to Er: YAG lasing, while in Group C, fissurotomy followed by acid etching was done. The sealant placement was carried out using split tooth design in all the samples. Assessment of penetration and adaptation was done under scanning electron microscope using the scoring criteria adopted by Kane B et al. and Dukic W et al.

Results:

Group A and Group C showed better adaptation than Group B. Statistically, no significant difference was observed in the penetration property among three techniques. Similarly, the unfilled and filled sealant showed statistically nonsignificant results for the penetration and adaptation comparison.

Conclusion:

Irrespective of the sealant material selected, the conventional method of acid etching alone or in conjunction with fissurotomy bur for better retentiveness seems to be an acceptable choice of treatment modality. The study will help the clinicians to choose the sealant material and technique of enamel preparation.
Association of SRXN1 Receptor Gene Polymorphism with Susceptibility to Periodontitis
Authors: Murthykumar Karthikeyan , Varghese Sheeja , Jayaseelan Vijayashree Priyadharsini
Published: November 2022

Background:

Emerging evidence suggests that oxidative stress forms a key component in the etiopathogenesis of periodontitis. Literature evidence have shown potential antioxidants responsible for combating the pro-oxidants which stress the periodontium, but the peroxiredoxin-sulfiredoxin system is explored very minimally in periodontal disease. Thus, the present study was aimed to evaluate the genetic association of SRXN1 receptor gene polymorphism (rs6053666).

Materials and Methods:

A total of 100 subjects were recruited for this study, which included 50 Periodontitis patients (Stage II and above based on the criteria of American Association of Periodontology-2018) and 50 periodontally healthy or mild gingivitis. Genomic DNA was extracted from the whole blood collected from the subjects. DNA was amplified using specific primers flanking the BtgI region of the SRXN1 receptor gene. The amplicon was further subjected to genotyping using restriction fragment length using BtgI enzyme. The genotype obtained based on the restriction fragment length polymorphism pattern was recorded and used for statistical analysis. The distribution of genotypes and allele frequencies in the periodontitis and control groups were compared using the Chi-square test. The risk associated with individual alleles or genotypes was calculated as the odds ratio with 95% confidence intervals. Statistical significance in all tests was determined at P < 0.05.

Results:

The genotype frequency and distributions of SRXN1 receptor BtgI polymorphism did not differ significantly at x2df (P = 0.557). Our study results showed that homozygous and heterozygous mutant genotypes had no significant difference (CC vs. CT + TT) between the periodontitis patients and control group with a P = 0.4266. The detected frequency of CT (38% vs. 34%) and TT (42% vs. 52%) genotype showed no significant difference between control and test group. There was no significant difference in C allele (39% vs. 31%) and T allele (61% vs. 69%) between the test and control group.

Conclusion:

The present study denotes that SRXN1 receptor gene polymorphism is not associated with periodontitis in the study group analyzed.
Three-Dimensional Collagen Membranes Challenging the Gold Standard in Gingival Recession
Authors: Narayan Siddharth , Kaarthikeyan G.
Published: November 2022

Gingival recession is a commonly encountered chief complaint in a dental office, most commonly presenting as pain or sensitivity on intake of food or sometimes just seen as an esthetic concern which may present in a localized or generalized form. Such interest toward dental esthetics has encouraged clinicians to formulate newer minimally invasive surgical techniques which are short but still deliver predictable long-term benefits in restoring the patient’s smile. One such method was evaluated in the present short communication where a commercially available, biodegradable, and volume-stable collagen membrane was used to manage gingival recession instead of donor grafts. The clinical parameters which were assessed after a period of 9 months demonstrated an increased width of attached gingiva and overall tissue thickness after surgical intervention. These findings along with successful mean root coverage of the upper left canine would seem to challenge the results obtained while using similar procedures and donor grafts, the age-old gold standard bio-filler. The dawn of esthetic dentistry is here with more emphasis on how physical appearance bolsters confidence and morale among younger individuals. Among the various complaints concerned with patient`s esthetic, periodontal plastic surgery is one of the more challenging procedures. The real obstacle while performing such procedures is achieving complete or partial root coverage over an avascular bed, whereas multiple variables seem to affect the overall clinical outcome.

From the Jewish Cemetery to Wawel: Activities of the Hochstims, a Family of Jewish Stonemasons from Kraków

The article is devoted to the activities of the Hochstim family: Jewish stonemasons active in the second half of the nineteenth century, mainly in Kraków, but also in other Galician towns and in Warsaw (Kingdom of Poland). Four generations of this family were active in the field of stonemasonry. The highest position was achieved by Fabian Hochstim (1825–1906) who completed prestigious commissions such as the renovation of royal tombstones on Wawel Hill. His enterprise, which for many years was located in Kraków’s main square, specialized in the production of tombstones for both Jewish and Christian cemeteries. Fabian’s son, Adolf, pursued his father’s business and also sold building materials. The Hochstim family employed modern business strategies to establish the corporate identity of their enterprise, such as participation in public exhibitions and marketing campaigns in the press. With success and despite obstacles they achieved a strong market position in an environment that was dominated by traditional guilds. Until the end of the nineteenth century, the family remained faithful to the Jewish tradition.

Opening Jewish Houses of Prayer: Legal and Administrative Arrangements and Clerical Pragmatics in the Piotrków Governorate between the End of the Nineteenth and the Beginning of the Twentieth Centuries

The article shows a revision of the religious policy of the administrative authorities of the Piotrków Governorate Government regarding the initiative of opening new Jewish prayer houses. This change of attitude is best illustrated by archival materials, mainly of the Administrative Department of the Piotrków Governorate Government, stored in the State Archive in Łódź. A detailed analysis of historical documents revealed the actual attitude of the tsarist civil authorities to Jews residing in this area. While a relatively tolerant approach to the needs of Jewish communities was observed at the end of the nineteenth century, governorate clerks rigorously blocked their progression at the beginning of the next century. The ways used to legally restrict the opening of new prayer houses and the Jewish administrative struggle with the official interpretation of the Russian Empire law are discussed in the article.

Ershte Yudishe Shakh-Tsaytung and Ershte Yudishe Sport-Tsaytung: The First Yiddish Sports Magazines Published in Łódź and Their Contents

The main purpose of the article is to broaden the state of knowledge about Yiddish press published in Łódź. The author focuses on two periodicals dedicated to sport: Ershte Yudishe Shakh-Tsaytung and Ershte Yudishe Sport- Tsaytung that were issued in 1913 and 1914. They were considered as missing and ephemeral with no important contribution to the history of Polish Jews. The analysis of two inconspicuous magazines leads to the conclusion that expands research in the field of press or biography studies, revealing interesting information especially about the milieu of people gathered around the widely defined cultural life in Łódź, adding some unknown facts about Arthur Szyk, Moshe Broderzon or David Frishman, and enriching knowledge about the formative processes in the Jewish cultural life in the city.
„Od powietrza, głodu i pomnika Kuny zachowaj nas Panie”. Antysemicki spór o pomnik Adama Mickiewicza dla Wilna

“From Air, Hunger, and the Monument by Kuna Protect Us, Lord”: The Antisemitic Dispute over the Adam Mickiewicz Monument for Vilnius

After Poland regained independence in 1918, a considerable group of Polish Jews wanted to co-create Polish culture, which did not find approval in the eyes of nationalists, defenders of the purity of national culture. Writers and artists of Jewish origin, especially those assimilated, became the main target of attacks and victims of social ostracism. The story of the monument of Adam Mickiewicz proposed to the city of Vilnius by Henryk Kuna, a sculptor with Jewish roots, may serve as a case study, perfectly illustrating both the power of resentment among the broad masses of society at the time and the influence of journalists. Kuna’s project was the third (after Zbigniew Pronaszko’s avant-garde monument and Stanisław Szukalski’s symbolist one) project of a Mickiewicz monument for Vilnius, selected in a competition in 1932. Unlike the previous ones, it did not seem to be controversial either in terms of form (it represented modernized classicism) or symbolism (it showed the poet in a pilgrim’s cloak with a book in one hand, the other hand covering his eyes). Despite this, nationalist circles unleashed an antisemitic campaign, striking at both the artistic and iconographic value of the statue. A rich variety of rhetorical means, from wit to virulent mockery, prove that it was not aesthetic preferences that played a dominant role here, but Henryk Kuna’s background, which influenced the evaluation and interpretation of his work.

Jewish Issues in the Daily Newspaper Słowo Pomorskie in the Years 1938–1939

The article deals with Jewish issues appearing in the daily newspaper Słowo Pomorskie in the years 1938–1939. The newspaper was published in Toruń in the years 1920–1939 and covered the Pomerania Province (Pomorskie Province) at that time. In the article, the political character of Słowo Pomorskie and its importance for local structures of the National Party (Stronnictwo Narodowe) are discussed. The newspaper usually presented a negative image of the Jewish population, which was connected with the antisemitic attitude of the nationalist groups. The author also describes the role of the Catholic clergy in propagating the anti-Jewish attitudes. The antisemitic contents is divided into thematic categories—foreign and domestic issues are separated. The analysis of the newspaper texts shows, among other things, the affinity of the antisemitic views of the National Party with other movements of this kind in Europe. In the Polish context, the hatred toward Jews did not diminish on the eve of the outbreak of World War II, but rather became radicalized.
Explainable Deep Learning approach for Shoulder Abnormality Detection in X-Rays Dataset
Authors: Mall Pawan , Singh Pradeep
Published: November 2022

Computer vision researchers and decision-makers have struggled to understand how deep neural networks (DNNs) accomplish image classification tasks and interpret their results. Due to a lack of understanding of their internal functioning, these models are commonly referred to as "black boxes." As a part of the development process, the DNNs can be easily explained. In this research work, we introduce an explainable technique for shoulder abnormality detection. The motivation behind this study is to enhance patients' and medical professionals' trust in DNNs technology. DNNs are implemented frequently in the medical domain. The suggested abnormality detector, which is based on IGrad-CAM++, is capable of detecting Shoulder X-rays abnormality. Grad-CAM is a common approach that combines the activation maps received from the model to create such a visualization. The average gradient-based terms used in this technique, on the other hand, understate the contribution of the model's identified representations to its predictions. In order to address this issue, we offer a technique that uses Grad-CAM++ to compute the route integral of the gradient-based terms. By assessing different techniques, it is discovered that the recommended procedure can perform very effectively and efficiently in X-ray images provides more visual explanation than existing techniques.

Published: November 2022

Psychological factors play a very important role in visha. The definition of visha itself gives the term depression. When the person is affected by visha, there are not only symptoms of body but mind is also involved. There are references of shanka visha, sarpangaabhihata etc. where mind is involved. From a psychiatric standpoint, exposure to toxins can increase the risk of depression, suicide, ADD/ADHD, learning problems, memory problems and dementia, brain fog, autism, temper outbursts, and psychotic behavior. Over the last four decades, there has been the unprecedented development and release of a swelling repertoire of potentially toxic chemicals which have the capability to inflict brain compromise. The treatment of poisoned person depends on the mental status of that person, if the person is frightened, depressed the treatment given becomes of less effective. The treatment modalities of visha like mantra, Sajna Sthapana, Harshana and Santvana signifies the importance of psychological factors. This article highlights the importance of psychological factors in visha.

Abstract. Nitrogen dioxide (NO2) column density measurements from satellites have been widely used in constraining emissions of nitrogen oxides (NOx = NO + NO2). However, the utility of these measurements is impacted by reduced observational coverage due to cloud cover and their reduced sensitivity toward the surface. Combining the information from satellites with surface observations of NO2 will provide greater constraints on emission estimates of NOx. We have developed a deep-learning (DL) model to integrate satellite data and in situ observations of surface NO2 to estimate NOx emissions in China. A priori information for the DL model was obtained from satellite-derived emissions from the Tropospheric Chemistry Reanalysis (TCR-2). A two-stage training strategy was used to integrate in situ measurements from the China Ministry of Ecology and Environment (MEE) observation network with the TCR-2 data. The DL model is trained from 2005 to 2018 and evaluated for 2019 and 2020. The DL model estimated a source of 19.4 Tg NO for total Chinese NOx emissions in 2019, which is consistent with the TCR-2 estimate of 18.5 ± 3.9 Tg NO and the 20.9 Tg NO suggested by the Multi-resolution Emission Inventory for China (MEIC). Combining the MEE data with TCR-2, the DL model suggested higher NOx emissions in some of the less-densely populated provinces, such as Shaanxi and Sichuan, where the MEE data indicated higher surface NO2 concentrations than TCR-2. The DL model also suggested a faster recovery of NOx emissions than TCR-2 after the Chinese New Year (CNY) holiday in 2019, with a recovery time scale that is consistent with Baidu “Qianxi” mobility data. In 2020, the DL-based analysis estimated about a 30 % reduction in NOx emissions in eastern China during the COVID-19 lockdown period, relative to pre-lockdown levels. In particular, the maximum emission reductions were 42 % and 30 % for the Jing-Jin-Ji (JJJ) and the Yangtze River Delta (YRD) mega-regions, respectively. Our results illustrate the potential utility of the DL model as a complementary tool for conventional data-assimilation approaches for air quality applications.
Aerosol characteristics and polarimetric signatures for a deep convective storm over the northwestern part of Europe – modeling and observations
Authors: Shrestha Prabhakar , Mendrok Jana , Brunner Dominik
Published: November 2022

Abstract. The Terrestrial Systems Modeling Platform (TSMP) was extended with a chemical transport model and polarimetric radar forward operator to enable detailed studies of aerosol–cloud–precipitation interactions. The model was used at kilometer-scale (convection-permitting) resolution to simulate a deep convective storm event over Germany which produced large hail, high precipitation, and severe damaging winds. The ensemble model simulation was, in general, able to capture the storm structure, its evolution, and the spatial pattern of accumulated precipitation. However, the model was found to underestimate regions of high accumulated precipitation (> 35 mm) and convective area fraction in the early period of the storm. While the model tends to simulate too high reflectivity in the downdraft region of the storm above the melting layer (mostly contributed by graupel), the model also simulates very weak polarimetric signatures in this region, when compared to the radar observations. The above findings remained almost unchanged when using a narrower cloud drop size distribution (CDSD) acknowledging the missing feedback between aerosol physical and chemical properties and CDSD shape parameters. The kilometer-scale simulation showed that the strong updraft in the convective core produces aerosol-tower-like features, increasing the aerosol number concentrations and hence increasing the cloud droplet number
concentration and reducing the mean cloud drop size. This could also be a
source of discrepancy between the simulated polarimetric features like
differential reflectivity (ZDR) and specific differential-phase
(KDP) columns along the vicinity of the convective core
compared to the X-band radar observations. However, the use of narrow CDSD
did improve the simulation of ZDR columns. Besides, the
evaluation of simulated trace gases and aerosols was encouraging; however,
a low bias was observed for aerosol optical depth (AOD), which could be
partly linked to an underestimation of dust mass in the forcing data
associated with a Saharan dust event. This study illustrates the importance and the additional complexity
associated with the inclusion of chemistry transport model when studying
aerosol–cloud–precipitation interactions. But, along with polarimetric
radar data for model evaluation, it allows us to identify and better constrain the traditional two-moment bulk cloud microphysical schemes used in the numerical weather prediction models for weather and climate.

Abstract. Ammonia (NH3) is one of the most important gases emitted from agricultural practices. It affects air quality and the overall climate, and in turn influenced by long term climate trends as well as by short term fluctuations in local and regional meteorology. Previous studies have established the capability of the Infrared Atmospheric Sounding Interferometer (IASI) series of instruments aboard the Metop satellites to measure ammonia from space since 2007. In this study, we explore the interactions between atmospheric ammonia, land and meteorological variability, and long-term climate trends in Europe. We investigate the emission potential (Γsoil) of ammonia from the soil, which describes the soil – atmosphere ammonia exchange. Γsoil is generally calculated in-field or in laboratory experiments; here, and for the first time, we investigate a method which assesses it remotely using satellite data, reanalysis data products, and model simulations. We focus on ammonia emission potential during March 2011, which marks the start of growing season in Europe. Our results show that Γsoil ranges from 2 × 103 to 9.5 × 104 (dimensionless) in a fertilized cropland, such as in the North European Plain, and is of the order of 10–102 in a non-fertilized soil (e.g. forest and grassland). These results agree with in-field measurements from the literature, suggesting that our method can be used in other seasons and regions in the world. However, some improvements are needed in the determination of mass transfer coefficient k (m s-1), which is a crucial parameter to derive Γsoil. Using a climate model, we estimate the expected increase in ammonia columns by the end of the century based on the increase in skin temperature (T skin), under two different climate scenarios. Ammonia columns are projected to increase by up to 50 %, particularly in Eastern Europe, under the SSP2-4.5 scenario, and might even double (increase of 100 %) under the SSP5-8.5 scenario. The increase in skin temperature is responsible for a formation of new hotspots of ammonia in Belarus, Ukraine, Hungary, Moldova, parts of Romania, and Switzerland.

Abstract. Streams convey coarse-clastic sediments towards coasts, where interactions with deltaic and coastal processes determine the resultant landscape morphology. Although extracting hydroclimatic signals from landscapes is a desired goal, many studies rely on interpreting paleoclimatic proxies and the link between depositional/geomorphic processes and the hydroclimate remains vague. This is a consequence of the challenge to link processes that often are studied separately, span across large spatial and temporal scales including synoptic-scale hydroclimatic forcing, stream flows, water body hydrodynamics, fluvial and coastal sediment transport, and sedimentation. Here, we explore this chain of connected processes in the unique setting of the Dead Sea basin, where present-day hydroclimatology is tied closely with geomorphic evolution and sediment transport of streams and coasts that rapidly respond to lake-level fall. We use a five-years-long (2018–2022) rich dataset of (i) high-resolution synoptic-scale circulation patterns, (ii) continuous wind-wave and rain-floods records, and (iii) storm-scale fluvial and coastal sediment transport of varied-mass, ‘smart’ and marked boulders. We show that Mediterranean cyclones approaching the eastern Mediterranean are the main circulation pattern that can provide sufficient rainfall and winds that concurrently activate two perpendicular sediment conveyors: fluvial (floods) and coastal (wind-waves). The synoptic-scale westerlies (>10 m s-1) are orographically funneled inside the Dead Sea rift valley, turning into surface southerlies. They generate 10–30 high-amplitude northward propagating storm waves per winter, with <4 m wave height. Such storms transport cobbles for hundreds of meters alongshore, north of the supplying channel mouths. Towards the decay of the storm wave, the high-altitude synoptic westerlies provide moisture to generate 4–9 flash-floods, delivering unsorted coarse gravels into the basin. These gravels are dispersed alongshore by waves only during subsequent storms. As storm waves dominates and are >five times more frequent than flash-floods, coarse-clastic beach berms and fan-deltas are deposited preferentially north of channel mouths. This depositional architecture, controlled by regional hydroclimate, is identified for both the modern and Late Pleistocene coast and delta environments, implying that the dominance of present-day Mediterranean cyclones has persisted in the region since the Late Pleistocene when Lake Lisan occupied the basin.
Reconstructing tephra fall deposits via ensemble-based data assimilation techniques

Abstract. In recent years, there has been a growing interest in ensemble approaches for modelling volcanic plumes. The development of such techniques enables the exploration of novel methods for incorporating real observations into tephra dispersal models. However, traditional data assimilation algorithms, including ensemble Kalman filter methods, can yield suboptimal state estimates for positive-definite variables such as volcanic aerosols and tephra deposits. This study proposes two new ensemble-based data assimilation techniques for semi-positive-definite variables with highly skewed uncertainty distributions, including aerosol concentrations and tephra deposit mass loading. The proposed methods are applied to reconstruct the tephra fallout deposit resulting from the 2015 Calbuco eruption using an ensemble of 256 runs performed with the FALL3D dispersal model. Two datasets of deposit thickness measurements are considered: an assimilation dataset including 161 observations, and a validation dataset for an independent assessment of the methods. Results show that the assimilation leads to a significant improvement over the first-guess results, obtained from the simple ensemble forecast. The spatial distribution of the tephra fallout deposit thickness and the ashfall volume according to the analyses are in good agreement with estimations based on field measurements and isopach maps reported in previous studies. Both assimilation methods show a similar performance in terms of evaluation metrics and spatial distribution of the deposit. Finally, the potential application of the methodologies for the improvement of ash-cloud forecasts produced for operational models is also discussed.
Investigating coastal backwater effects and flooding in the coastal zone using a global river transport model on an unstructured mesh

Abstract. Coastal backwater effects are caused by the downstream
water level increase as a result of elevated sea level, high river
discharge and their compounding influence. Such effects have crucial impacts
on floods in densely populated regions but have not been well represented in
large-scale river models used in Earth system models (ESMs), partly due to
model mesh deficiency and oversimplifications of river hydrodynamics. Using
two mid-Atlantic river basins as a testbed, we perform the first attempt to
simulate the backwater effects comprehensively over a coastal region using
the MOSART river transport model under an ESM framework, i.e.,
Energy Exascale Earth System Model (E3SM) configured on a regionally refined
unstructured mesh, with a focus on understanding the backwater drivers and
their long-term variations. By including sea level variations at the river
downstream boundary, the model performance in capturing backwaters is
greatly improved. We also propose a new flood event selection scheme to
facilitate the decomposition of backwater drivers into different components.
Our results show that while storm surge is a key driver, the influence of
extreme discharge cannot be neglected, particularly when the river drains to
a narrow river-like estuary. Compound flooding, while not necessarily
increasing the flood peaks, exacerbates the flood risk by extending the
duration of multiple coastal and fluvial processes. Furthermore, our
simulations and analysis highlight the increasing strength of backwater
effects due to sea level rise and more frequent storm surge during
1990–2019. Thus, backwaters need to be properly represented in ESMs to
improve the predictive understanding of coastal flooding.

Abstract. The EU and UK have made ambitious commitments under the net-zero plans to decarbonise their economies by 2050. For this, offshore wind will play a major role, significantly contributing to a paradigm shift in the power generation
and greater volatility of electricity prices. The operating strategy of wind farms should therefore move from power maximisation to profit maximisation which includes income from providing power system services and the reduction
of maintenance costs. Wind farm flow control (WFFC) is a key enabler for this shift through mitigation of wake effects in the design and operation phases. The results of the FarmConners market showcases presented here are the first attempt to economically assess WFFC strategies with respect to electricity market prices. Here, we present a conceptual simulation study starting from individual turbine control and extend it to layouts with 10 and 32 turbines operated with WFFC based on the results of five participants. Each participant belonged to a different research group with their respective simulation environments, flow models and WFFC strategies. Via a comparative analysis of relative WFFC benefits estimated per participant, the implications of wind farm size, the applied control strategy and the overall model fidelity are discussed in zero-subsidy scenarios. For all the participants, it is seen that the income gain can differ significantly from the power gain depending on the electricity price under the same inflow, and a favourable
control strategy for dominant wind directions can pay off even for low electricity prices. However, a strong correlation between income and power gain is also observed for the analysed high-electricity-price scenarios, underlining the need for additional modelling capabilities to carry out a more comprehensive value optimisation including lower prices and system requirements driven cases.

The ubiquitousness of social media has made it an effective strategy for firms to communicate with consumers. Despite its relevance, it can be daunting and confusing when used as a marketing tool. This study examines the influence of social media marketing on customer-brand engagement in the banking industry. Based on a quantitative design, data were collected from 224 active followers of commercial banks’ social media pages in Nigeria. Cronbach’s alpha was used to test the reliability of the data while the hypotheses were analyzed using multiple regression analysis. The result showed that the social media marketing dimensions of entertainment, personalization and eWOM positively and significantly affect customer-brand engagement. Therefore, it was recommended that firms should design and develop contents that are fun, exciting, and resonates with customers and customize content to customers’ interests. Also, firms should incentivize customers to share their brand experiences on their platforms.
