What can transactional data reveal about the prevalence of menstrual pain in England?
Authors: Sivill Torty , Ljevar Vanja Ljevar , Goulding James , Skatova Anya
Published: September 2023

Introduction & BackgroundIt has been reported that up to 91% of those who menstruate experience associated pain. Despite its ubiquity, the prevalence of menstrual pain has been under researched due to stigma, disregard from medical professionals and a lack of data. It has also been reported that different demographics experience menstrual pain differently yet the impact of socio-demographic factors on menstrual pain remains to be explored on a national scale due to data scarcity.

Objectives & ApproachIn this study, we propose one way to overcome this data barrier, using a novel measure of menstrual pain extracted from supermarket shopping data. We use these national datasets to identify individual customer behaviour patterns. Specifically, we use transactions involving both a pain and menstrual item as a proxy measure for menstrual pain. We investigate national menstrual pain sales and whether there are significant differences between deprived and less deprived areas of England.

Relevance to Digital FootprintsThis paper brings together data from multiple sources, to provide a population level analysis of the prevalence of menstrual pain England. We use transactional data from a pharmaceutical retailer to develop a novel proxy measure for menstrual pain. We use various machine learning algorithms to explore the relationship between transactional data and various data sources pertaining to social deprivation.

ResultsOur findings indicate that there is a high prevalence of menstrual pain with at least 26.7% of customers who purchase menstrual items also purchasing pain relief simultaneously. These customers are nearly four times more likely to purchase pain relief with a menstrual item than they are without. In addition, our results indicate a significant geographical disparity between menstrual pain transactions. We examine the relationship between a variety of deprivation factors and regional menstrual pain transactions and find average regional income has the highest predictive impact on menstrual pain sales. Contrary to what would expected from previous research, customers from the region with the lowest regional income were a third less likely (32%) to make a menstrual pain transaction than those from the highest income region.

Conclusions & ImplicationsThis work motivates further research into the national prevalence of menstrual pain to understand why this regional disparity exists and whether it is a consequence of "period poverty". A better understanding of the sociodemographic factors associated with menstrual pain will help healthcare professionals stratify patients by risk, and could inform strategies to predict and prevent menstrual pain and its adverse impacts.
Data donation of individual shopping data to help predict the occurrence of disease: A pilot study linking individual loyalty card and health survey data to investigate COVID-19
Authors: Dolan Elizabeth , Goulding James , Skatova Anya
Published: September 2023

Introduction & BackgroundPrevious studies have found shopping data could increase the predictive accuracy of disease surveillance systems and illuminate behavioural responses in the self-management of symptoms of disease. Yet, accessing individual sales datasets for linkage to health datasets is challenging, and the recruitment of appropriate sample sizes for medical research has been limited.

Objectives & ApproachObjectivesCollect and link individual health data to individual shopping data to investigate COVID-19. Assess the feasibility of scaling-up this method, and use the collected data to investigate using loyalty card data in machine learning (ML) models for disease.

MethodsBased on recommendations on the public’s preferences for data donation a new protocol was designed for collecting, linking and analysing shopping and health data. Participants were requested to use the Tesco Clubcard website data portability function to share their loyalty card data and complete an online health survey. An exploratory data analysis was conducted on the linked dataset. Participants were recruited online (18/01/2022 to 04/02/2022) with a recruitment target of 200.

Relevance to Digital FootprintsThe collection and analysis of individual transactional sales data for health research.

Results197 participants shared their Tesco Clubcard and health survey data. Tesco Clubcard data contained 893,414 transactions of 65,310 uniquely named items purchased from 2015 to 2022. Average transactions per participant were 4,653 (SD 5256) and average timeframe recorded was five years 6 months and 30 days (SD 836 days). A total of 6,993 medication sales were recorded accounting for 1% of sales, 81% (159/197) of participants bought medications and the average was 44 (STD 68) medications per individual. Most participants (196/197) shared their health status in the survey, and 94% (81/86) of those on medication shared the medication names. Participants reported donating their data to do good (79%, 155/197), help the NHS (77%, 152/197), be socially responsible (74%, 144/197) and because data was secure and anonymised (78%, 153/197).

Conclusions & ImplicationsUsing this new protocol which enables convenient data sharing with transparent data safeguards, the public were willing to share both their shopping and health data for research into COVID-19. To apply robust ML analysis, particularly to explore self-medication at an individual level, recruitment must be significantly scaled to collect data from enough individuals with high sales and regular shopping frequency, or new ML techniques developed to address sparseness in loyalty card data of key purchasing events related to health. The study suggests public readiness to share shopping data for health research, but investment is needed for large-scale data collection and AI application.
Longitudinal reliability of Twitter sentiment for measuring mental health and well-being in a UK birth cohort
Authors: Di Cara Nina , Di Davis Oliver , Haworth Claire
Published: September 2023

Introduction & BackgroundSocial media data is increasingly recognised as an important source of behavioural data. It can provide insights into patterns of life and how individuals and groups are feeling. However, many studies into social media’s relationship to mental health and well-being have suffered from poorly developed ground-truth data, which relies on assumed ground-truth labels and data from single timepoints. This means that the accuracy of models at future timepoints cannot be assessed.

Collecting Twitter data from cohorts provides a solution to this issue, given the many years of high quality data that can be used as ground truth. Cohorts can also benefit from the higher-resolution data provided by social media that can supplement their traditional data collection methods.

Objectives & ApproachWe used Twitter data that has been collected with consent from two generations of the Avon Longitudinal Study of Parents and Children (ALSPAC) (N=656). The data is linked to two surveys completed in April-May 2020 and May-July 2020 for validated outcome measures of anxiety, depression, and general well-being.

Using the LIWC and VADER sentiment algorithms, the sentiment categories most highly associated with each outcome were used to develop a multiple regression model for each of anxiety, depression and general well-being using the first survey timepoint. Error from these models in predicting the second timepoint allowed us to assess how well different outcomes are predicted by demographic group.

Relevance to Digital FootprintsDigital footprint data can complement traditional data sources to provide a more nuanced view of health inequalities. These data are typically less timely to collect than traditional data collection methods (census, survey) allowing a more reactive response to emergent issues such as the cost-of-living crisis.

ResultsThis study illustrates how the collection of digital footprint data can be integrated into existing long-term studies which can be used to provide multiple points of ground-truth data.

Conclusions & ImplicationsThis study has shown that the collection and integration of Twitter data into cohort studies is feasible, and that cohort data provides multiple ground-truth options. This time series data is important for assessing the potential feasibility of mental health inference from online behavioural data, which this study shows may vary across personal characteristics.

In future research we plan to link subsequent surveys from ALSPAC to provide more ground truth time points and explore the temporal stability of predictions, and impacts of model drift on performance.
Exploring spatial patterns of vulnerability using linked health data
Authors: Brake Abigail , Birks Daniel , Mon-Williams Mark , Relins Sam
Published: September 2023

Introduction & BackgroundThe types of challenges police and ambulance services deal with often overlap, for instance supporting those who suffer from mental ill-health. Research has shown that emergency service problems often concentrate, but also that some individuals who come to the attention of one service may not be as visible to another despite their overlap in roles.

Objectives & ApproachThis study explored how routinely collected 999 data may reveal insights into how these services support potentially vulnerable populations. We argue that better understanding the nature and distribution of vulnerability-related calls may help to inform future preventative or harm reduction-based interventions. We analysed administrative data provided by Yorkshire Ambulance Service for the Bradford region through the Connected Bradford research database, posing the following questions: (1) can 999 call data provide insights into vulnerability-related incidents attended by ambulances?; (2) where and when are these incidents most prevalent?; and (3) what are the spatial patterns of calls and patient home locations associated with them?

Relevance to Digital FootprintsWe first select calls associated with nine callout reasons indicative of vulnerability. Patients can choose to share their data with each healthcare service they use, so we harnessed this digital footprint to analyse the spatial distribution of call locations (at postcode sector level) and patient home location (at MSOA level).

ResultsResults indicate substantial concentrations of vulnerability-related calls in multiple postcode sectors including the City Centre (where we estimate 18% of calls may be vulnerability-related) and several other areas which are associated with deprivation. Exploring flows of people from their home location to incident location we also see substantial spatial variation in the locations in which patients involved in these types of incidents reside.

Conclusions & ImplicationsThese analyses represent initial efforts to better understand how vulnerable groups are supported by public services, and have the potential to inform future resource allocation and targeting of upstream interventions.
Behavioural entropy as an individual difference
Authors: Poon Neo , Goulding James , Skatova Anya
Published: September 2023

Introduction & BackgroundThe availability of digital footprints data have provided new and invaluable opportunities for personality psychologists. One way to study individual differences with digital footprints data is through the lens of entropy, which is a measure of the degree of randomness of a probabilistic system. When applied to individual behaviour, entropy captures how predictable an individual’s (e.g., shopping) pattern of behaviour is over time.
In this study, we proposed that entropy can be conceptualised as a proxy measure of Openness, a Big Five personality trait. We further studied entropy’s associations with external behavioural outcome, namely the voting outcomes of the 2016 EU ‘Brexit’ referendum in the UK. This referendum asked UK citizens whether the UK should stay in the EU (vote Remain) or leave the EU (vote Leave). It has been demonstrated that Leave (or ‘Brexit’) vote was heavily influenced by attitudes towards immigration which is associated with values of being less ‘open’ to other cultures, and therefore we expected that entropy – or tendency to try new things – would be associated positively with voting Remain.
Objectives & ApproachWith a massive data set (20,550,952 customers) provided by a large UK retail chain over a period of 2 years, we computed aggregated entropy for the Local Authority Districts (LADs). Further we investigated the relationships between entropy and personality traits, as well as between entropy and the referendum outcomes, at geographically aggregated levels.
Relevance to Digital FootprintsThis study brought together digital footprints data with external sources. This study also identified population level insights by examining personality traits and their utility in predicting sociopolitical outcomes.
ResultsResults of a linear regression model showed strong evidence supporting a positive relationship between entropy and Openness (b = 0.30, t = 3.30, p = .001), and a negative relationship between entropy and Neuroticism (b = -0.48, t = -3.53, p < .001).
Further, entropy was associated with outcomes of the EU referendum in each LAD. Results of another linear regression model showed strong evidence supporting a positive relationship between the percentage of Remain votes and entropy (b = 0.28, t = 4.80, p < .001).
Conclusions & ImplicationsThe relationship between Big Five trait Openness and entropy provided support that personality can be inferred from digital footprints data such as shopping history records. The positive relationship between entropy and the proportion of Remain vote demonstrated that people who are more open to new experiences voted Remain. Our findings have broader implications showing that it is possible to find associations between personality traits extrapolated from shopping data and real-world choices.
Carbon foot printing school meals: data linkage and engagement activity
Authors: Dalton Alexandra , Ennis Emily , Green Melinda , Morris Michelle A
Published: September 2023

Introduction & BackgroundFood production is a substantial contributor to greenhouse gas emissions and climate change. A more sustainable diet is often a healthier one, so making lower carbon food choices serves to benefit the planet and person. In order to understand the carbon footprint of food choices, linkage of recipe information to carbon footprint data and transaction records is required. To inform positive change insights from data linkage must be communicated to the target audience, in this case schoolchildren.

Objectives & ApproachSchool dinner recipe information and transaction records for school meals at five schools for a six week period were acquired. Carbon footprint estimates were calculated for each recipe, using published data. An automated dashboard was created in order that these calculations could be replicated by catering teams. Carbon footprints were appended to the school transaction records for meal choices. An interactive web game was created in ‘top trump’s' style using a selection of the recipes, with carbon footprint and popularity ranking, generated from the transaction records.

Relevance to Digital FootprintsTransactional meal sales data from schools are digital footprint data. In this work we link these digital footprint data to detailed recipe information with estimated carbon footprints from an open data source.

ResultsThe Consumer Data Research Centre Carbon Calculator and The Planet Plates game were created. The Carbon Calculator is being used in a number of settings to support food procurement and recipe development. The Planet Plates game has been used in Leeds Schools to empower schoolchildren to make positive changes to lower the carbon footprint of their meal choices. The children were engaged with all the activities and not only learned about sustainability of their food choices, but about how data they generate can be used anonymously for public good.

Conclusions & ImplicationsData linkage of digital footprint data is a powerful tool for behaviour change to tackle some of the world’s most pressing challenges. Methods and insights should be shared widely and made accessible to a range of stakeholders wherever possible.

Influence of marketing environment factors on the development of retail trade in Ukraine
Authors:   Lviv Polytechnic National University, Kosar Natalia , Vintoniak A. ,   Lviv Polytechnic National University
Published: September 2023

Retail trade in Ukraine is an important branch of its economy and significantly affects the satisfaction of the population's needs for consumer goods. Based on the analysis of secondary marketing information, it was determined that the volumes of retail turnover of enterprises operating in the field of retail trade increased significantly in 2021 compared to 2013. The influence of changes in certain factors of the macro- and microenvironment on the functioning of retail trade enterprises of Ukraine was studied. It has been established that their development is positively influenced by the cultural environment and the scientific and technical environment. At the same time, the political environment (political instability due to military actions in Ukraine), the economic environment (decrease in the level of population income, inflation, reduction of GDP), the demographic environment (migration of the population, reduction in its number) have a significant negative impact on the functioning of retail trade enterprises of Ukraine. At the beginning of the full-scale invasion of Russia into Ukraine, as a result of the destruction of warehouses and shops in a number of regions of our country, the disruption of relations with suppliers, and the shortage of a number of goods, retail enterprises suffered significant losses. Having closed stores in temporarily occupied territories or where active hostilities are taking place, large retail chains in 2022 opened a number of new stores in the Western regions of Ukraine and in the city of Kyiv, significantly changing the territorial structure of retail trade. The destruction of manufacturing enterprises or the limitation of their capacities forces retailers to look for new suppliers of goods, reduce their product range, and optimize logistics. The functioning of retail trade enterprises was significantly affected by the COVID-19 pandemic. There was a significant increase in the number of online stores of food retailers, "click and collect", "click and drive" services appeared. Today, there is a sharp increase in the prices of goods, compared to the pre-war period, which, in the conditions of a reduction in the level of income of the population of Ukraine, limits the volume of their purchases in physical terms. Having slightly adapted to the new conditions, retail enterprises need to intensify their marketing activities to increase the volume of purchases by store visitors and expand their customer base.
The essence and features of financing startup enterprises
Authors:   Lviv Polytechnic National University, Adamiv Marta , Lysa D. ,   Lviv Polytechnic National University
Published: September 2023

The current state of development of Ukraine's economy requires solving the problems of intensifying entrepreneurial activity, including in the form of startups. The results of the analysis of existing scientific works and practical materials made it possible to clarify the essence of a startup, which should be understood as the process of creating and bringing to the market an innovative product which requires attracting financial resources to promptly solve specific problems under conditions of high uncertainty. Whereas an enterprise that will be engaged in the implementation of this process should be called a startup enterprise. One of the key obstacles to the development of startup enterprises is the limited financial resources, which requires attracting external financing. The results of studying the literature allowed to identify the basic stages (rounds) of financing the activities of startup enterprises, namely: Pre-seed round, during which a startup enterprise starts its activities (at this stage, startup enterprises are valued at $10 thousand to $100 thousand, and their projects can receive funding of up to $50 thousand); Seed round, during which startup enterprises are able to cover the necessary costs of creating an innovative product, preparing marketing tools, forming a team of employees and conducting further market research (at this stage, startup enterprises are valued at $3 million to $6 million, and a promising startup project can receive funding in the amount of $50 thousand to $3 million); Series A financing round, where a startup company must have a developed product and a customer base with a constant revenue stream (at this stage, startup companies worth $10 million to $30 million, that have a sound business plan can raise up to $10 million); Series B financing round is for startup companies that have passed the previous three financing rounds, have a sufficient customer base with a recurring revenue stream and have proven to investors that they can succeed on a larger scale (at this stage, startup companies worth $30 million to $60 million can raise up to $30 million); Series C financing round is for startup companies seeking larger amounts of funding to create new innovative products, enter new markets, and acquire other inefficient startups in their own or related industries (at this stage, startup companies with business growth worth $100 million to $120 million can raise up to $50 million); Series D financing round allows entrepreneurs to raise funds to solve problems in a special situation (the value of startup companies at this stage can be estimated from $150 million to $300 million, and they are able to raise up to $100 million); initial public offering (IPO), which growing startups in need of funding often use to raise funds, while established successful organizations use it to allow owners of startups to sell shares to the general public and thus partially or fully divest themselves of ownership.

Analytics for modern business in the conditions of martial law. In particular, it is stated that corporate analytics is aimed at attracting investments, increasing business competitiveness and the efficiency of entrepreneurship, and implementing digital technologies. Corporate analysts play a key role in the implementation of these measures. Corporate analysts are called to help their company or customer carry out effective transformations, offer the most creative and innovative solutions, breaking down the company's strategy into separate initiatives that make it possible to bring tangible benefits to customers. Therefore, the key skills of such specialists were formed in the article. It was established that corporate analysts should possess a high level of knowledge, develop effective communications, analyze farsightedly, critically, weigh and make conclusions, be open to new knowledge, and be able to present reasonable conclusions of the conducted research in an accessible manner. Such analyst competencies make it possible to distinguish the components of corporate analytics, namely: system analytics, business analytics, financial analytics, HR analytics, information analytics, web analytics and predicative analytics, which in turn is divided into descriptive and prescriptive analytics. These components form the structure of corporate analytics. As a result, it was proposed to interpret corporate analytics as methods and means of systematic observation, collection, processing, systematization and analysis of information for the purpose of evaluating the current and retrospective states of the external and internal environments of enterprises, human resources, the efficiency of business processes, functions, actions and operations, modeling and forecasting their prospective states with the help of information and telecommunication technologies to support the adoption and implementation of optimal management decisions. Prospects for further research will be a detailed analysis of the components of corporate analytics.

Published: September 2023

Modern trends of globalization and the development of the world economy convincingly testify the need to rethink the ways and models of doing business under the influence of IT systems and technologies. This opens new prospects for business. The Internet has become a modern space for conducting business, which significantly expands the possibilities of displaying the real economy in the virtual global world. The consequence of the above-mentioned processes is the development of such an economic and legal phenomenon as electronic business. The concept and essence of "electronic business" and the peculiarities of its development in the conditions of the digital economy formation are studied. The article examines the basic concepts and principles of e-business, its advantages and disadvantages, e-business management technology. It also describes the main types of e-business, such as e-commerce, e-business management and others. The article considers examples of the implementation of electronic business systems based on foreign and Ukrainian companies’ experience. Based on the analysis, recommendations are provided for the development of e-business in Ukraine and the prospects for its further development. The introduction and development of the e-business system in Ukraine is an important step in the development of the country's economy. At the same time, several problems must be solved for the effective functioning and spread of e-business. One of the biggest problems complicating conducting electronic business in Ukraine is the imperfection of the regulatory framework, which requires the development of uniform rules for conducting electronic transactions that would meet international standards. For this, it is necessary to actively involve scientists, experts and the business community in the development of normative acts. It is also necessary to solve the problems of creating a reliable e-business infrastructure, based on providing high-speed Internet access and supporting cyber security. One of the critical issues is the training of e-business specialists. The Ukrainian educational system should be able to provide proper training of specialists who would know how to create and maintain an electronic business.
The impact of cognitive distortions of economic development
Authors:   Lviv Polytechnic National University, Mamchyn Myroslava , Yarychevska Y. ,   Lviv Polytechnic National University
Published: September 2023

The article studies cognitive distortions (illusions) and the possibilities of using cognitive and emotional factors to make decisions by different market actors in conditions of uncertainty. The theoretical foundations of the irrational behavior of economic actors, based on cognitive or social reasons, are highlighted. The authors note that the functioning of the cognitive sphere of a person is often accompanied by certain errors that are scientifically attributed to cognitive distortions in the rational behavioral paradigm that cause distortions in the perception of reality. Based on the understanding that the behavior of the human brain is sufficiently rational, since its work aims to save resources, resulting in logical errors, in other words, cognitive distortions that are caused by limited cognitive resources, as well as external limiting factors or insufficient motivation. Therefore, it can be considered that since the brain uses cognitive illusions to save resources to accelerate decision making, said process has evolved evolutionarily in order to survive. It has been established that the inability of the human brain to fully process the entire huge body of information when making decisions and leads to the existence of cognitive distortions, which in turn can negatively affect not only the geopolitical situation in the world, but also cause the death of many other people, so it is necessary to thoroughly investigate their influence on the behavior of economic actors. The article explores two systems of thinking. In the I system, thinking is distinguished by the intuitiveness of the decisions made, the high speed of thought processes with their minimal awareness. In the II system, thinking is characterized by controllability, systematicity, rationality, that is, it is logically justified and conscious. Based on the characteristics of each of the systems, it is possible to understand how individuals make decisions and what were the subconscious reasons for a particular reaction. Factors affecting the behavior of individuals and the causes of cognitive distortions that can be taken into account when building economic incentives and even economic processes in general have been identified. The influence of the most faithful cognitive illusions on different types of economic entities is outlined. Proper diagnosis of cognitive distortions in the behavior of economic entities in business in the future will allow, with the help of proper influences, to transform it into the desired state.

Cekaman kekeringan memberikan dampak pada padi sawah tadah hujan di dunia sebesar 23 juta hektar. Pengujian cekaman kekeringan pada stadia perkecambahan padi dapat dilakukan dengan larutan osmotik mannitol. Penelitian mengenai toleransi cekaman kekeringan menggunakan mannitol pada stadia perkecambahan padi belum pernah dilakukan di Indonesia. Tujuan penelitian ini adalah mensimulasikan tekanan osmotik dan mengidentifikasi batas toleransi cekaman kekeringan terhadap kinerja fisiologis benih padi varietas Inpari 19, Inpari 32 dan Inpari 49. Percobaan simulasi tekanan osmotik (0 MPa, -0.03 MPa, -0.05 MPa, -0.08 MPa dan -0.11 MPa) menggunakan konsentrasi mannitol (0%, 2%, 4%, 6% dan 8%) diterapkan pada benih padi Inpari 19, Inpari 32 dan Inpari 49. Parameter daya berkecambah, kecepatan tumbuh, indeks vigor, panjang akar, jumlah akar dan panjang kecambah diamati sebagai respon fisiologi penanda perkecambahan toleran cekaman kekeringan. Analisis non parametrik diterapkan pada penelitian ini, karena seluruh respon fisiologi benih tidak memenuhi asumsi normalitas dan homogenitas ragam. Hasil uji Bredenkamp menunjukkan perbedaan konsentrasi mannitol yang menghasilkan tekanan osmotik berbeda memberikan pengaruh nyata terhadap fisiologi benih varietas Inpari. Penurunan tekanan osmotik dibawah perlakuan mannitol mengakibatkan penurunan nilai DB, IV, KCT, PA, JA dan PK dari varietas Inpari 19, Inpari 32 dan Inpari 49. Ketiga varietas padi yang digunakan mempunyai toleransi cekaman kekeringan pada media tanam dengan tekanan osmotik sebesar -0.03 MPa (mannitol 2%).

Authors: Xuegang Z. , Xiaobin H. , Bin G.
Published: September 2023

Curvilinear cylindrical gear drives are a type of parallel-axis gear set, and the longitudinal geometrical shape of the gear teeth is a part of the circular arc. The main purpose of this paper is to explore the influence of modification amount and assembly error on con-tact stress and bending stress. This study proposes a curvilinear cylindrical gear drive with a parabolic profile. The gear tooth surfaces are generated by a face-milling cutter with a straight-line profile, and the matching gear tooth surfaces are generated by a face-milling cutter with the parabolic profile. Initially, mathematical models of the gear set are described based on the theory of gearing. The finite element method and tooth contact analysis algorithms were applied to contact and bending stress analyses. Finally, four numerical examples are provided to illustrate the mechanical performance of the curvilinear cylindrical gear drive with the parabolic profile. The study results show that curvilinear cylindrical gear drives have superior mechanical performance compared to those with a straight-line profile.

Published: September 2023

At present, the researches on the mechanical properties of sand aggregate mainly focus on the shaping process of particles, and lack the researches on the crushing mechanism. This paper first defines the shaping process of stone powder wall, and explores the crushing mechanism of sand aggregate by adopting multiple times of small energy crushing. The effect of energy is investigated by simulation and experiment. The machine-made sand crushing mechanism is analyzed by establishing corresponding contact mathematical models. The result shows that the stone powder wall involves two mathematical models under impact: the elastic-plastic model at low impact velocity and the elastic-brittle model at high impact velocity.
Aikuisten suomen kielen ja luku- ja kirjoitustaidon opiskelijoiden osallistumisen keinojen kehittyminen luokkahuonevuorovaikutuksessa

Tässä artikkelissa tarkastelen multimodaalisen keskustelunanalyysin keinoin aikuisten luku- ja kirjoitustaitoon tukea tarvitsevien suomenopiskelijoiden osallistumisen keinojen kehittymistä luokkahuonevuorovaikutuksessa kahdeksan kuukauden aikana. Aluksi kartoitan kolmen fokusopiskelijan osallistumiskeinojen kokonaiskuvan kahdessa eri aikapisteessä. Videoaineistosta hahmottuu kaksi erilaista oppijaprofiilia: aktivoituja ja alkujaankin aktiivinen osallistuja. Tämän jälkeen tarkennan analyysin näiden oppijaprofiilien edustajien kirjoitusaktiviteetteihin liittyvien avunpyyntöjen kehittymisen tarkasteluun. Näytän, että avun pyytäminen opettajalta muotoutuu ajan mittaan aktivoitujalla rutiininomaiseksi osallistumisen keinoksi luokkahuonevuorovaikutuksessa. Jo alkujaan aktiivinen osallistuja kehittyy etenkin kyvyssään toimia ymmärrettävästi avunpyyntösekvenssin edetessä. Tulosten pohjalta esitän, että toisen kielen oppimista koskevassa pitkittäistutkimuksessa on tarkoituksenmukaista käyttää analyyttisena yksikkönä sekvenssiä yksittäisten kielellisten ilmausten, vuorojen tai sosiaalistentoimintojen lisäksi. Multimodaalisen analyysin vahvuus vuorovaikutuskompetenssin kehittymisen tarkastelussa on, että se huomioi myös kehollisten keinojen ja tilanteiden sekventiaalisen etenemisen kokonaisvaltaisemmin.
An Observational Study of Risk Factors for SARS-CoV 2 Infection in Patients with Cancer
Authors: Singla Sonam , Wadhwa Teena , Yadav Charu , Singh Manish , Sarma Smita , Sood Nitin , Vaid Ashok
Published: September 2023

Introduction: Cancer patients are regarded as a highly vulnerable population in Coronavirus Disease 2019 (COVID-19) pandemic due to their systemic immunosuppressive state. The aim of the study was to investigate the prevalence of SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2) infection in asymptomatic cancer patients attending the oncology clinic.
Methods: We conducted a retrospective observational study from May- November 2020. The patients who tested positive for SARS-CoV-2 RT PCR were followed up to study the risk factors, clinical presentation, and outcome. The ethical approval from institutional review board was done. Chi-square test was used to compare qualitative variables and logistic regression model was used to estimate the odds ratio (OR) of having COVID-19 infection.
Results: We included 334 cancer patients who were tested for COVID-19 infection. The prevalence of SARS-CoV-2 infection was 28.4%. COVID-19 infection was more common in solid organ malignancy than hematological cancer (29.2% vs. 26.1%). The risk of COVID-19 infection was associated with comorbidity (p = 0.002). Time since diagnosis of malignancy and the type of anticancer treatment received did not increase the risk of COVID-19 infection. However, patients receiving anticancer therapy in the last 4 weeks of testing positive for SARS-CoV-2 RT PCR had a higher risk for COVID-19 infection (p<0001). The oncological treatment was continued after resolution of symptoms and with negative RT-PCR. The multi variable regression model revealed that females, patients having both hypertension and diabetes mellitus and patients receiving chemotherapy within the last 4 weeks had higher odds of COVID-19 infection (p<0.05).
Conclusion: We observed that active oncologic treatment does not represent a risk factor for SARS-CoV-2 infection in cancer patients. However delaying anticancer treatment to avoid SARS-CoV-2 transmission may lead to malignancy related complications. The approach of routine COVID 19 testing in cancer patients seems preferable in detecting asymptomatic virus carriers.

Penyandang disabilitas di masyarakat dimaknai sebagai seseorang yang mengalami kelainan atau keterbatasan baik dari segi fisik maupun mental. Dalam melakukan aktivitas sosialnya di masyarakat, penyandang disabilitas dianggap sebagai manusia yang tidak mampu untuk ikut serta dalam kegiatan sosial, sehingga penyandang disabilitas dan keluarganya kerap mengalami pengucilan dan penindasan hak dari orang normal lainnya. Diperlukanlah dukungan sosial untuk menunjang rasa keberpihakan terhadap disabilitas, salah satunya dari sosok terdekat, yakni Ibu. Hal inilah yang melatarbelakangi penelitian untuk mengetahui bagaimana sosok seorang ibu ideal yang memiliki anak disabilitas digambarkan dalam film animasi “Nussa dan Rara’ episode Nussa Bisa. Penelitian ini menggunakan pendekatan kualitatif metode analisis semiotika Roland Barthes yang meliputi tiga level pemaknaan, yaitu denotasi, konotasi dan mitos. Hasil dari penelitian ini ditemukan bahwa penggambaran sosok Ibu Nussa nampaknya tidak bisa lepas dari emosional yang berbeda-beda, namun kemudian batin yang terjadi dapat konflik dapat diselesaikan karena adanya sikap menerima dan ikhlas dengan segala ketentuan yang telah diberikan oleh Allah swt.  Mitos yang muncul adalah ekspresi kecemasan namun juga perhatian, citra ideal seorang ibu yang mengayomi, memprioritaskan anak, memberikan motivasi yang dilakukan dalam segala geraknya agar dikemudian hari anak-anaknya tumbuh menjadi generasi yang ceria dan pribadi yang baik sesuai dengan tuntunan al-qur’an dan al-hadits.

Pluralisme dalam hierarki tatanan sosial masyarakat merupakan sebuah fenomena yang tidak mungkin dihindari. Konsep pluralisme sudah ada sejak zaman Nabi Muhammad SAW hingga sekarang. Namun persebaran gagasan ini mengalami kontroversi dan penolakan dari berbagai kalangan sehingga menimbulkan pro dan kontra. Sebagai masyarakat majemuk, idealnya harus bisa hidup dalam pluralisme dengan menjalin harmoni hidup beragama. Menampilkan rasa hormat dan toleransi satu sama lain tanpa harus meyakini keberadaan kebenaran pada agama dan keyakinan agama lain. Berdasarkan konteks di atas, maka muncul pertanyaan bagaimana nilai-nilai pluralisme dalam film lima? Analisis yang akan digunakan adalah teori Question of representation dari Branston dan Stafford (2003: 90-116). Teori ini menjelaskan bagaimana representasi menjalankan proses pembentukan suatu identitas tertentu secara berulang-ulang terhadap objek yang dicitrakan didalam media. Terdapat tiga konsep dari teori ini yaitu stereotyping, representation and the real, question of positive and negative images. Konsep pertama mengkaji asumsi negatif yang tersebar luas tentang kelompok tertentu. Konsep kedua menggambarkan sesuatu secara realita dan tidak terdistorsi. Konsep ketiga mengenai pandangan positif dan negatif  masyarakat terhadap suatu kelompok tertentu.Streotip yang dibangun di dalam film lima yakni isu rasisme dan intervensi dalam menilai seseorang bukan berdasarkan prestasi melainkan ras dan warna kulit.
TAYANGAN PERSIDANGAN KASUS PEMBUNUHAN BRIGADIR J SEBAGAI PILAR INDEPENDEN MEDIA

Artikel ini menggambarkan peran media untuk mendukung penegakan keadilan di Indonesia, yang dibuktikan dengan bentuk mengawasi dengan cara menayangkan prosesi persidangan kasus sambo oleh media yang tidak sekedar opini. Walaupun tak semua media mengikuti dengan cara menyiarkan secara langsung gelar prosesi persidangan kasus Sambo atas pembunuhan Brigadir J, namun bentuk tayangan yang selalu berkala menginformasikan secara jelas tayangannya, yang pada awalnya media juga sempat bungkam hanya mengikuti keinginan skenario yang ditayangkan secara berulang. Maknanya adalah, media berpihak kepada masyarakat dalam mengawal kasus Brigadir J hingga akhir. Masalahnya ketika media tidak berpihak kepada masyarakat maka pemberitaan akan hilang dan kasus mampu ditutupi dari pandangan publik dalam menginginkan keadilan ditegakkan.  Sikap seperti ini dapat digunakan sebagai bukti bahwa media tidak mampu independen lagi, karena bisa distir oleh permerintahan dan institusi yang memiliki kekuatan ekonomi dan politik.
