Межпоколенческий цифровой разрыв в России
Authors: Варламова Юлия Андреевна
Published: April 2022

Различия между поколениями в использовании цифровых технологий приобретают особое значение в свете старения населения, увеличения продолжительности жизни и поиска путей включенности старшего поколения в активную социальную жизнь. Фокус исследования сосредоточен на использовании Интернета в России. Цель исследования  ‒ выявить различия в доступе и использовании Интернета представителями разных поколений. Исследование проводилось на основе выделения трех уровней цифрового разрыва: первый уровень ‒ доступ к Интернету, второй ‒ использование Интернета, третий  ‒ выгоды от использования Интернета. В работе использованы данные Российского мониторинга экономического положения и здоровья населения НИУ ВШЭ. Основными методами исследования являются сравнительный анализ, анализ динамики показателей, метод расстояния во времени. Результаты исследования позволили: (1) выявить специфические черты во владении гаджетами, имеющими выход в Интернет, среди поколений; (2) проследить динамику межпоколенческого разрыва первого и второго уровня в  использовании Интернета на протяжении 2012–2019 годов; (3) оценить межпоколенческие разрывы в доступе и использовании Интернета с использованием метода расстояния во времени. Результаты исследования позволяют констатировать существование различий в доступе и использовании Интернета между поколениями как с точки зрения владения цифровыми гаджетами, так и с точки зрения целей использования Интернета. Наличие цифрового разрыва между молчаливым поколением и более молодыми поколениями позволяет сделать вывод о необходимости учета особенностей использования интернет-услуг и интернет-сервисов представителями старших поколений, оказания им помощи по инклюзии в цифровую среду. При этом отмечена положительная динамика среди представителей всех поколений в освоении Интернета. Оценка цифрового разрыва третьего уровня позволила сделать вывод о наличии выгод для всех поколений в России от использования Интернета.

Published: April 2022

The 6-minute walk test (6MWT) is a field test commonly used to predict VO2peakin people after stroke. Inclusion of cardiodynamic variables measured by impedance cardiography (ICG) during a 6MWT has been shown to improve prediction of peak oxygen consumption (VO2peak) in healthy adults but these data have not been considered in people after stroke. This study investigates whether the prediction of VO2peak can be improved by the inclusion of cardiovascular indices derived by impedance cardiography (ICG) during the 6MWT in people with strokeThis study investigates whether the prediction of VO2peak can be improved by the inclusion of cardiovascular indices derived by impedance cardiography (ICG) during the 6MWT in people with stroke This study investigates whether the prediction of VO2peak can be improved by the inclusion of cardiovascular indices derived by impedance cardiography (ICG) during the 6MWT in people with stroke. Our study showed that inclusion of SV and CO measured during the 6MWT in stroke patients further improved the VO2peak prediction power compared to using 6MWD as a lone predictor.

A Note on the Estimation of the Maximum Possible Earthquake Magnitude Based on Extreme Value Theory for the Groningen Gas Field
Authors: Zöller Gert
Published: April 2022

Extreme value statistics is a popular and frequently used tool to model the occurrence of large earthquakes. The problem of poor statistics arising from rare events is addressed by taking advantage of the validity of general statistical properties in asymptotic regimes. In this note, I argue that the use of extreme value statistics for the purpose of practically modeling the tail of the frequency–magnitude distribution of earthquakes can produce biased and thus misleading results because it is unknown to what degree the tail of the true distribution is sampled by data. Using synthetic data allows to quantify this bias in detail. The implicit assumption that the true Mmax is close to the maximum observed magnitude Mmax,observed restricts the class of the potential models a priori to those with Mmax=Mmax,observed+ΔM with an increment ΔM≈0.5…1.2. This corresponds to the simple heuristic method suggested by Wheeler (2009) and labeled “Mmax equals Mobs plus an increment.” The incomplete consideration of the entire model family for the frequency–magnitude distribution neglects, however, the scenario of a large so far unobserved earthquake.

Estimation of Intensity Duration Frequency for Ungauged Basin in Lampung Province, Indonesia
Authors: Susilowati  , Alisjahbana Sofia W. , Kusumastuti Dyah Indriana
Published: April 2022

Frequency duration intensity (IDF) analysis was conducted to estimate the peak flow rate based on the minimum rainfall data collection station. Rainfall data used is data with high intensity that occurs in a short time from automatic rainfall recording stations. Currently, the availability and distribution of automatic rain recording stations in Lampung Province, Indonesia, are still limited. Therefore, this study aims to use the IDF approach in the ungauged basin area for areas with rainfall data that do not meet the hydrological analysis criteria by interpolating rainfall data from 126 manual rainfall measuring stations in Lampung Province, Indonesia. The research method includes analysis of rainfall intensity using the Mononobe equation at various durations and returns periods. Next, create a rainfall intensity map (isohyet) using ArcGis. Finally, compare the IDF analysis of daily rainfall data at 4 automatic rainfall gauge stations with the estimation results based on the intensity map (isohyet). Based on the results of data analysis, it is known that from the available 126 rainfall climatology stations, there are 113 rainfall climatology stations with complete data for 10 years and 13 rainfall climatology stations with incomplete data for 10 years. In addition, the study results show that 45.24% of the daily rainfall in Lampung province is in the low category, 53.97% is in the medium category, and 0.79% is in the high category. This study indicates that rainfall intensity data from climatological rainfall stations that do not meet the hydrological criteria can be found by interpolating rainfall intensity maps from the nearest rain climatology station that meet the hydrological analysis criteria. The relationship test of the actual rainfall intensity variable at 4 automatic rainfall gauge stations with the rainfall intensity from the map (isohyet) using MAPE showed satisfactory results.
Factors Influencing Lymph Node Metastasis From Supraglottic Laryngeal Carcinoma
Authors: Dabirmoghaddam Payman , Khaksar Nafiseh
Published: April 2022

In patients with supraglottic carcinoma (SGLC), lymphatic metastasis is frequent and can cause a significant reduction in local control rate and survival. Currently, the preferred method of neck treatment in patients with supraglottic cancer is prophylactic bilateral neck dissection that could result in overtreatment in at least two thirds of patients. The purpose of this study is to evaluate factors influencing neck metastasis and to determine whether routine elective neck dissection is necessary for the management of all SGLCs. 66 patients with SGLCs who underwent transoral laser surgery and neck dissection were included in this study. The rate of overall and occult lymphatic involvement was 29% and 20%, respectively. The most common involvement site was level II, and factors such as T category, tumor grade, epilarynx involvement, and extension of tumor to the medial wall of pyriform sinus were significantly related to cervical lymph node metastasis. In conclusion, our results suggest that in selected patients with SGLC (such as small T1 or lateralized tumors), elective neck treatment could be ignored, and instead, close follow-up be considered.

Published: April 2022

To explore the presence of aflatoxin B1 (AFB1) and fungi in traditional drugs collected in Vietnam. Materials and Methods: 505 samples of 88 different traditional drugs were obtained from 10 hospitals in Nghe An, a central province of Vietnam. AFB1 contamination was determined by a high-performance liquid chromatography (HPLC) assay. Fungal contaminants were determined according to WHO regulations, and the obtained Aspergillus strains were characterized via morphological and molecular identiﬁcation. Results: 24 samples (4.75% of the total samples) were contaminated with AFB1, and the average concentration was 0.062±0.030 µg/kg (ranging from 0.009 to 0.097 µg/kg). Fungal isolates were detected from 174 samples (34.45%). The genus Aspergillus was predominant (82.76% of the isolates), but Rhizopus, Alternaria, Corynespora, and yeast were also found in a few samples. Among 144 strains of Aspergillus recovered, A. niger (105 strains) was most frequently found, followed by A. tubingensis (31 strains), A. oryzae (4 strains), and A. flavus (4 strains). Conclusion: This study suggests a low risk of aflatoxin B1 exposure to consumers of traditional drugs in Vietnam.

Effect of service quality PT. Cross Marga Sedaya on consumer satisfaction in use e-toll card on Cipali toll road
Authors: Budiastuti Endah , Agustin Nindiya
Published: April 2022

This research is motivated by the finding when the toll gates on the Cipali toll road do not provide transaction service satisfaction and services that are not in accordance with customer expectations such as the availability of substations at the gate which in reality cannot meet the surge in customers, especially during working hours and on holidays. In addition, the availability of ramps is also not proportional to the number of vehicles exiting the Cipali toll gate. This shows that there are problems regarding transaction services which have implications for the low transaction speed of toll road customers. To test these variables, researchers used hypothesis testing using simple regression and quantitative methods using correlational techniques. The data analysis technique uses a simple regression technique. The results showed that the influence of  PT.Lintas Marga Sedaya's  service quality  on  consumer satisfaction in using the E-Toll Card on the Cipali toll road was in the very strong category. This is based on the value of rcount = 0.937 which is in the correlation interval 0.800–1,000 with a very strong category. In order to determine the significance level at = 0.05 (5%) the value of tcount = 26,216 and ttable = 1.66105. Thus, tcount > ttable, which means that there is a significant effect between variable X on variable Y, where the contribution of service quality to satisfaction is large. consumers by 87.9% and the remaining 12.1% is influenced by other factors not examined in this study.

Authors: Zhang Yuejuan , Bi Songshan , Niu Zhiqiang , Zhou Weiya , Xie Sishen
Published: April 2022

Rechargeable aqueous Zn-ion batteries (AZIBs) are considered alternative stationary storage systems for large-scale applications due to their high safety, low cost, and high power density. However, Zn anode issues including dendrite formation and side reactions greatly hinder the practical application of AZIBs. To solve the Zn anode issues, various strategies based on material designs have been developed. It is necessary to analyze and classify these strategies according to different materials, because different properties of materials determine the underlying mechanisms. In this review, we briefly introduce the fundamental issues in Zn anodes. Furthermore, this review highlights the material designs for the protection of Zn anodes in mild AZIBs. Finally, we also offer insight into potential directions in the material designs to promote the development of AZIBs in the future.
Дослідження причин старіння архівних документів та способів їх стабілізації
Authors: Талімонова Надія Леонідівна , Омельченко Ірина
Published: April 2022

З кожним роком, внаслідок природного старіння, документи та видання на паперовій основі втрачають свою міцність та стають більш схильними до руйнування. Вплив внутрішніх та зовнішніх факторів лише прискорюють цей незворотній процес. Тема дослідження причин старіння та стабілізації архівних документів є особливо актуальною та має на меті визначення згубного пливу шкідливих чинників і розробку комплексу заходів для нейтралізації їх дії і призупинення процесу природного старіння.
Під час роботи над даною статтею було класифіковано основні фактори вплину на старіння архівних документів. Внутрішніми факторами впливу є безпосередньо склад паперу, фарб, клеїв та вид палітурних матеріалів. Зовнішні чинники: умови освітленості, температура та вологість, хімічний склад навколишнього середовища та біологічні фактори. Недотримання умов зберігання призводить до утворення плісняви, пошкодження різними видами комах, зниження показника читабельності текстів, підвищення крихкості, деформації на полях видань та в корінцю.
В результаті проведених досліджень було виявлено, що різні наповнювачі в структурі паперу, такі як крейда, підвищують його стійкість до зміни кольору під дією ультрафіолетового випромінювання. Крейдований офсетний папір в порівнянні з газетним та некрейдованим офсетним папером має нижчий показник зміни кольору, що був визначений способом інсоляції зразків впродовж різних проміжків часу. Швидкість руйнування залежить від спектральної характеристики, інтенсивності та тривалості випромінювання.
Під час природного старіння документів спостерігаються зміни молекулярної структури целюлози для мінімізації яких використовують різні методи стабілізації документів. Обов’язковим етапом є нейтралізація кислотності паперу. Методи стабілізації документів поділяють на обробку у водних розчинах та «суха» обробка. Для збереження цілісності видань використовують фазову консервацію. Інкапсуляція рекомендована лише для аркушевих документів.
Природне старіння документів є незворотним процесом, проте використання розробленого алгоритму працівниками архівів та музеїв дає можливість дещо призупинити даний процес.

Published: April 2022

Estudar a satisfação dos comensais com o restaurante universitário é importante para possibilitar identificar aspectos tangíveis e intangíveis que influenciam para tal satisfação. Assim, objetivando estabelecer uma discussão entre satisfação dos comensais com o cardápio e serviço prestado em restaurante universitário e os fatores a eles associados, entrevistamos 556 comensais do serviço de alimentação em Universidade Federal no nordeste brasileiro. Para identificar quais atributos das preparações eram previsoras para satisfação com a composição do cardápio e para avaliar os atributos previsores para gostar do elemento do cardápio, realizamos regressão multinomial. A correlação entre frequência ao restaurante e satisfação com higiene, cordialidade e comunicação dos funcionários realizamos correlação de Spearman. Dentre os entrevistados, 96,05% eram estudantes, que realizavam principalmente o almoço (48,40%) e frequentavam constantemente o restaurante (55,80%). O sabor foi o atributo com influência para os comensais gostarem de nove preparações e o aspecto visual de seis. Os fatores associados a total satisfação com a composição do cardápio foram sabor (IC95%: 1,264-3,279), variedade (IC95%: 1,284-3,303) e quantidade (IC95%: 1,273-2,971) da salada; visual do feijão (IC95%: 1,063-3,289), bebida (IC95%: 1,289-3,777) e arroz (IC95%: 1,049-2,670). Assim, concluímos que a satisfação dos comensais com restaurante universitário está relacionada com a composição do cardápio.
The Multi-Level Model for Quarks and Leptons as the Symbiosis of Segal’s Chronometry with the Standard Model
Authors: Levichev Alexander , Palyanov Andrey
Published: April 2022

The Multi-Level Model (=MLM) was suggested by A. Levichev as a description of quarks and gluons. The review recalls MLM-terminology while MLM-findings (for quarks and leptons) are compared to the theoretical and experimental data as accepted by the Standard Model (=SM). MLM is based on Segal’s compact space-time U(2) and on the sequence of embeddings: U(2) into U(3), U(2) into U(4), etc. These groups were called the levels (of matter): U(2) - the 0th (that is, our mundane world), U(3) - the 1st, U(4) - the 2nd, etc. Such a convention matches the SM-quarks' generations list. Each SM-quark is viewed either as a sunken proton, or as a captured proton. The MLM-proton is elementary and indestructible (hence no need for confinement). For MLM-quarks, in terms of the notion of a ruling group, flavor and color are defined mathematically. The number of colors (and of flavors) is level-dependent. For levels U(3) through U(6) the correspondence with the SM-quarks is established. Three new quarks and two new leptons are predicted. The SM-puzzle of quark and lepton generations is solved. Using the Han-Nambu scheme, the notion of the quark’s electric charge is expressed in terms of color charges. The original part of the review suggests studying the proton’s properties (like mass, shape and inner pressure) on the ba-sis of its wave function.
Do Not Use I.F. for Scientific Value Estimation

Published: April 2022

A toy model for the distribution of the impact factor (IF) of a journal is proposed. The model demonstrates the presence of a heavy tail for the IF distribution, which occurs due to some random non-scientific circumstances. Therefore, the use of IF as an indicator of the quality of scientific papers seems to be inadequate.
High Malaria Mosquito Species Diversity, Their Blood Feeding Patterns, Role in Malaria Transmission and The Challenge of Morphological Classification: An Implication for Entomological Surveillance and Monitoring, Southwestern Ethiopia
Authors: Assa Adilo , Eligo Nigatu , Massebo Fekadu
Published: April 2022

There are a number of Anopheles species playing either primary or secondary roles in malaria transmission. Hence, understanding the species composition, their bionomics, and behaviors are all important in designing and implementing vector control intervention tools. Moreover, accurate identification of different species is vital. This study aimed to assess species composition, sporozoite infection rate, and blood meal origins of malaria mosquitoes in two malaria-endemic villages of Boreda district in Gamo zone, southwest Ethiopia. Thirty houses, 20 for Centers for Disease Control and Prevention (CDC) light traps and 10 for Pyrethrum Spray Catches (PSC), were randomly selected for bimonthly mosquito collection from October 2019 to February 2020. Enzyme-linked-immunosorbent assay (ELISA) test was done to detect the blood meal origins and circumsporozoite proteins (CSPs). The entomological inoculation rate (EIR) was calculated by multiplying the sporozoite and human biting rates from PSCs. Anopheles gambiae and An. funestus complexes were further identified into species by polymerase chain reaction (PCR). Anopheles species with some morphological structures confusing with An. gambiae or An. funestus complexes were father confirmed by PCR. A total of 15 Anopheles species were documented, of which An. demeilloni was the dominant one. Only An. arabiensis was positive for P. falciparum CSP. The overall P. falciparum CSP rate of An. arabiensis was 0.54%. The overall estimated P. falciparum EIR of An. arabiensis from PSC was 1.5 infectious bites/person/five months. Of the 145 freshly fed Anopheles mosquitoes tested for blood meal source, 57.9% (84/145) had bovine blood meal, 22 (15.2%) had human blood meal origin alone and 24 (16.5%) had mixed blood meal origins of human and bovine. An. demeilloni mainly fed on bovine blood (102/126 = 80.9%). Among 420 morphologically classified An. demeilloni, 11 (2.6%) were confirmed as An. lessoni (one of the An. funestus complexes) by PCR. A substantial number of morphologically classified An. salbaii, An. maculipalpis and An. fuscivenosus were found to be An. arabiensis by PCR. Regardless of the high diversity of Anopheles mosquitoes, An. arabiensis is playing the primary role in malaria transmission. Morphological misclassification of species could be a challenge in malaria mosquito monitoring and surveillance, and hence it should be supported by more sensitive techniques for confirmation.

The survival and resilience of food sellers in Indonesia during the Covid-19 pandemic is important to be discussed. This study proposes new strategies for food sellers in Indonesia based on customer reviews before and during the pandemic, and food sellers' competition profile. Customer reviews are scraped from 20 food sellers in Java, Indonesia. A text mining is then applied, and the texts collected are classified into 11 attributes. The next process is sentiment analysis to separate the positive and the negative reviews, to be analyzed further in two types of gap analyses. The first is gap analysis between positive and negative reviews to portray the food sellers’ strengths and weaknesses. The second gap analysis identifies the gap of customer reviews before and during the pandemic to predict the change of customers’ needs. The results show that product, place, and services are always the customer’s top-of-mind attributes, no matter in normal or pandemic situations, so that food seller should always maintain those aspects. This study also identifies several new strategies related to the health protocols. Regarding to online business competition, this study observes the food sellers’ growth in online marketplace. The result shows that the growth score of food sellers increases significantly from 2 to 9 per month because of the pandemic. Thus, food sellers need to consider the opportunity for online business, while maintaining their strengths. Compared to similar studies in other countries, the findings of this study differ in terms of the dominant attributes, related to different cultures.

In August of 2021, unexpected cracking was discovered in the concrete of newly constructed apartment towers and parking garages at Camp Walker, Daegu, South Korea. Initial evaluation by U.S. Army Corps of Engineers Far East District (USACE-POF) determined the towers to be safe for continued occupation. Out of an abundance of caution a team from the Engineer Research and Development Center (ERDC) conducted an independent evaluation of these structures to further verify life safety. Additionally, this evaluation sought to determine the potential causes of this cracking and remediation schemes both to inform future construction, but also to lay the groundwork for a more in-depth lifecycle evaluation by an Architectural/Engineering (AE) firm specializing in structural forensics. The ERDC evaluation consisted of on-site inspection, non-destructive testing, materials sampling and testing, and review of particular design and construction documentation provided by the Far East District. The results of the evaluation confirmed the Far East District’s findings that there was not a threat to life safety in these structures. Furthermore, the results of the ERDC evaluation indicated that drying shrinkage was the most likely causes of the observed cracking. In the areas where this cracking was the most severe, repair with epoxy injection was recommended for continued structural safety. In areas with moderate cracking, sealing of cracks was recommended to prevent long-term durability issues decreasing the lifespan of the structures.

Grisel’s syndrome, which involves non-traumatic atlantoaxial rotatory subluxation, is a rare disease that occurs primarily in children. Herein, we present two cases of chronic and acute Grisel’s syndrome that were successfully treated with traction and medication as non-surgical management. A 10-year-old male patient was diagnosed with chronic Grisel’s syndrome after surgery to remove cholesteatoma in his left ear 6 months previously (Case 1), and a 5-year-old female patient was diagnosed with acute Grisel’s syndrome after acute pharyngitis (Case 2). Both patients were treated with pain control and halo traction, which corrected torticollis and relieved their symptoms.

Published: April 2022

Background:Severe and complex cervical spondylotic myelopathy(CSM) requires surgical treatment, usually laminoplasty or laminectomy with lateral mass screw internal fixation. However, the operative effects of these surgical approaches are unclear.Therefore, we aimed to evaluate the clinical effects of posterior cervical laminectomy and lateral mass screw internal fixation in patients with severe and complex CSM.Methods:We retrospectively analysed 60 patients with severe and complex CSM who underwent posterior cervical laminectomy and lateral mass screw internal fixation between May 2013 and June 2020. C-spine radiographs, computed tomography scans, and magnetic resonance images were used to detect curvature and fusion of the cervical spine, restenosis, and loose/broken internal fixation screws. Clinical efficacy was evaluated using Japanese Orthopaedic Association (JOA)scores, the neck disability index (NDI), Odom’s classification, and the visual analogue scale (VAS) for pain.Results: At the last follow-up, there was no restenosis or loosened/broken internal fixations. The anterior curvature angle of lordosis (n=46) at the last follow-up was not different from that at baseline (P>0.05). The cervical kyphosis angle (n=14) at the last follow-up was improved compared with that at baseline (P<0.05), as were the JOA, NDI, and VAS scores (all P<0.05). Odom’s classifications at the last follow-up were excellent, good, and fair in 45, 12, and 3patients, respectively.Conclusions: Posterior cervical laminectomy and lateral mass screw internal fixation achieved satisfactory clinical results in severe and complex CSM cases:the cervical spine was stabilised, achieving spinal decompression while preventing excessive backward drift of the cervical spinal cord.

Objective: Ovarian cancer is one of the most common gynaecological malignancies among females worldwide. Early diagnostic of ovarian cancer is challenging, and miRNAs could serve as a potential biomarker for early detection of ovarian cancer regarding easy to detect. The present study investigated the expression profile of miRNA-34a, miRNA-143, miRNA-212, Sox4, BCL-2, and E2f5 in the serum of participants to find new biomarkers for early diagnosis of ovarian cancer. Materials and Methods: Five milliliters of whole blood were collected from each patient (n=30) and control (n=30), and total RNA was extracted using Ambion™ TRIzol™ Reagent. Real-time PCR methods evaluated the expression of targeted miRNAs and their targeted genes. Result: The Disease status of all ovarian cancer patients were classified as FIGO stage III (21) and (IV 9) according to imaging studies and surgical pathological findings. Our results showed that expression levels of miRNA-34a (p<0.0001), miRNA-143 (p=0.028), and miRNA-212 (p<0.0001) were significantly decreased in patients with ovarian cancer compared to controls and expression levels of Sox4(p<0.0001), BCL-2(p<0.0001) and E2f5(p<0.0001) were significantly increased in patients with ovarian cancer compared to controls. In addition, Receiver Operating Characteristic (ROC) curve revealed that the expression profile of miRNA-34a (AUC= 0.82; P <0.0001), miRNA-143 (AUC= 0.66; P = 0.026) and miRNA-212 (AUC= 0.78; P = 0.0001) could be used as potential biomarker for discriminating patients with ovarian cancer. Conclusion: In conclusion, our data showed that the expression profile of miRNA-34a, miRNA-143, and miRNA-212 could act as a potential biomarker for diagnosing ovarian cancer patients.

The Great Hungarian Plain (GHP) served as a geographic funnel for population mobility throughout prehistory. Genomic and isotopic research demonstrates non-linear genetic turnover and technological shifts between the Copper and Iron Ages of the GHP, which influenced the dietary strategies of numerous cultures that intermixed and overlapped through time. Given the complexities of these prehistoric cultural and demographic processes, this study aims to improve our understanding of diachronic and culture-specific dietary signatures. Here we report on stable carbon and nitrogen isotope values from 75 individuals from twenty sites in the GHP dating to a ~ 3000-year time span between the Early Bronze and Early Iron Ages. The samples broadly indicate a terrestrial C3 diet with nuanced differences amongst cultures, suggesting exogenous influences that manifested in subsistence strategies. Compared to the Iron Age, the Bronze Age samples have slightly elevated δ15N values implying higher reliance on protein. Interestingly, carbon values typical of C4 vegetation indicate the consumption of millet, or a grain with comparable δ13C values during the Middle Bronze Age. Overall, our results suggest a gradual transition in dietary patterns from the Early Bronze to Early Iron Age, demonstrating a relationship between subsistence and time periods, congruent with the archaeological record.
A Data-driven Fairness-based Time of Use Tariff Design

Published: April 2022

Time of use (TOU) tariffs aim to shape demand, by reducing peak demand and otherwise changing the load shape, which is of heightened relevance as energy supplies come under pressure and transition from fossil fuels to more volatile renewable sources. However, TOU tariffs may carry distributional consequences, such as higher bills for all users/low-income users. With the increasing prospect of steep increases in energy bills in Europe, a fairness-based approach TOU tariff design deserves proper attention by the world’s regulatory regimes. A flexible, fairness-based TOU tariff design is proposed, utilizing a 4-step data-driven approach to segment households by income and price responsiveness, followed by potential tariff filtering to simultaneously lower total costs, distribute cost savings progressively and maintain constant utility profitability. The new tariff design approach is demonstrated using the 2009-10 Irish Smart Metering Trial, and produces promising results.
