Impact of the COVID-19 Pandemic on Retail Sales of Health and Personal Care Stores in the United States
Authors: Gao Xiaohan , Zhang Hongyi , Zhang Sirui
Published: May 2023

In recent years, as a result of the Covid-19 pandemic, the health and personal care stores have been remarkably affected in a wide range of aspects. This became one of the reasons why medical staff felt pressure, leading to quite a number of staffs resigning, and meanwhile the management pattern of medical employees changes and seems to be more strict. Furthermore, the prevalence of Covid-19 pandemic also causes some mental diseases such as sleeping disturbance, anxiety as well as skin problems whether for adults or younger people. As a consequence, the health and personal care industry has been brought to light. This industry has become high in demand like never before. Therefore, complemented by daily and monthly U.S. coronavirus cases, retail sales of health and personal care stores in the USA is a time series worth analyzing. Best-fit ARIMA model for the retail sales is determined to be ARIMA (2, 2, 3) to forecast future health and personal care retail sales in hope of supporting the industry prepare for the ongoing pandemic and in case of another crisis. Regression models are built to find correlations between health and personal care retail sales and coronavirus cases. Additionally, this paper extended ARIMA by employing dynamic regression model which generates a more accurate forecast from regression with ARIMA (0, 1, 1) errors.
Financial Models and Portfolio Optimizations in the U.S. Market
Authors: Luo Qianwei
Published: May 2023

Portfolio optimization is an essential task for investors to maximize the profit and minimize the risk in trading, which can be reflected in return and standard deviation respectively. This article selects ten well-known firms and S&P 500 index as the portfolio and calculates their basic descriptive data of annualized return, annualized standard deviation, and correlations. Next, this article applies Markowitz model and Single-index model to the portfolio optimizations, as well as setting five constraints for comparison. After using the above methods, this paper gives the results in tabular and graphic ways. It finds that optimizing with no restriction can generate the biggest permissible regions of the minimum-variance frontier; investors only long stocks under constraint 4 can guarantee a finite risk and a finite positive return, which has a robust performance. Moreover, Markowitz model is flexible in covariances, but the number of estimates could complicate the calculating process; Index model is simple to calculate in linear regression form, but it’s not highly sensitive to the covariance matrix. The purpose of this article is to prove the feasibility of optimization in future portfolio management and helps investors to construct the portfolios with the fundamental theory of financial models.
Used Car Price Prediction by Using XGBoost
Authors: Qian Tingyu
Published: May 2023

This article demonstrates that by using methods such as Extreme Gradient Boosting (XGBoost), dummy variables, etc., the selling price can be accurately predicted according to the different conditions and variables of each used car. The used car dataset is divided into a training dataset and a test dataset according to the ratio of 83% and 17%. This article uses a total of three data processing methods to find the most accurate prediction method. The first is to remove the outliers of the training dataset and test dataset, and then directly use the xgboost prediction method for prediction. The second is to remove the outliers and remove the variable power that is most closely related to the price of the used car, and then use the xgboost prediction method to make predictions. The third method is to remove outliers and then normalize the training dataset and test dataset, finally using the xgboost prediction method to predict. The experimental results show that normalizing the dataset and then using XGBoost and dummy variables can be used to predict the selling price accurately and efficiently through the different usage conditions of each used car.
The Rise of the Sharing Economy
Authors: Luo Haiyang
Published: May 2023

Examining the sharing economy as an economic framework is the focus of this article. The sharing economy as a newly emerged economic pattern has become intensively discussed in the 21st century. It differs from traditional economic patterns, in which buyers buy goods from sellers. It rather shares assets like cars and houses by providing paid service through online platforms. Two famous examples that are talked about frequently in this article are Airbnb and Uber. These two enterprises are the most successful and influential, thus becoming the representatives of the sharing economy in recent years. Additionally, this article explores the pros and cons of the sharing economy. Shortly speaking, it is more flexible, more beneficial to the producers, and more friendly to the customers. The downside of it is that it lacks government regulations which may be necessary to prevent serious event happen. Overall, the sharing economy has already occupied a huge portion of the market and still grows at a believable speed. It has a bright future and it is worth studying.
Analysis and Prediction on the Top Retailers in the UK
Authors: Zhou Quan
Published: May 2023

The inflation in the UK has been increasingly serious, reaching approximately 10%. This directly causes the rise in the price of daily-used goods, including fresh and chilled, food cupboard and bakery, and household items. The growth in living costs has cut the shopping desire for the customers, pushing them to altering their original consumption habits. It is interesting to research in the behavior of the retailers during the inflation and the downturn of the UK economy. This paper has chosen four well-known retailers in the UK, Tesco, Sainsbury’s, Marks & Spencer’s and NEXT to represent the general development of the retail industry throughout the country. To evaluate the performance of the company before and after the influence, the stock price is used to indicate the current value of the four retailers. By collecting the data from Yahoo Finance and forecasting by applying Arima model, there will be no significant upwards or downwards tendency in the near future for Sainsbury’s and NEXT, while slight fluctuations are predicted to be shown for Tesco and Marks & Spencer’s stock price.
Prediction of Moderna Adjusted Closing Stock Price Trend Using ARIMA Model
Authors: Shao Yushu
Published: May 2023

Taking a glance at the pandemic, the adjusted closing stock price trend of Moderna company as an excellent sample is worth studying whether the statistical method of prediction can be used in an unnormal case. This paper examines whether the ARIMA model forecasting tool analyzes Moderna's adjusted closing stock price trend between the seventh of December twenty eighteen to the first of November twenty-two. The historical data of the closed stock price of Moderna Inc was collected from Yahoo Finance. Incorporating evidence from academic papers and the processing of computing the differences, judgement of stationary data and parameter selection, this study illustrates that the ARIMA model is a useful statistical tool to predict the stock trend. It argues for the limitations of using the ARIMA model and offers future outlooks. Ultimately, ARIMA [4, 1, 2] offers an appropriate model for summarizing the forecasting of the adjusted closing stock trend of Moderna Inc under the limited data in this case.
Inflation Measurement in the Era of COVID-19
Authors: Cui Xinyu
Published: May 2023

The outbreak of COVID-19 and the conflict between Russia and Ukraine have led to instability in the global economy and serious inflation in various countries, mainly due to sudden changes in household consumption patterns, countries differ in their initial response to the outbreak and the implementation of relevant policies, the sharp rise in energy prices and the monetary policies of various countries. The Chinese market has been the least affected due to China's timely control of the outbreak and the implementation of relevant policies to promote the economy in the later stage, while the US and European markets have not recovered to the pre-epidemic economic level so far. This paper analyzes the CPI and core-CPI data of the United States, Europe and China since the outbreak of COVID-19 in 2019, in order to judge the inflation situation of the United States, Europe and China under the double blow of COVID-19 and the Russia-Ukraine conflict.
Portfolios Optimization under Constraints
Authors: Liang Yi
Published: May 2023

This article selects 10 companies in the financial sector, energy sector and consumption sector, as well as SPX500 index. This paper uses two models, not only the Markowitz model but also the index model, to calculate the correlation coefficient matrix, minimum variance, maximum Sharpe ratio, capital allocation line and so on to analyze the return rate and volatility of 10 specific companies. Four limitations were calculated for Markowitz model and Index model respectively and the two models were compared under the same constraints. Because common financial constraints and specific industries are rarely noticed in reality, the results of this paper reflect the following three aspects: First, in order to strike a balance between risk and return, SPX is an investment worth considering due to its high correlation coefficient; the second is that for certain investors with added constraints, the capital allocation line performs relatively poorly, as does the minimum variance boundary. Thirdly, because the Markowitz model uses stock's covariance while the beta and alpha of stocks are components that the index model uses to construct a portfolio, the results show that under certain risk conditions, Markowitz model is inferior to index model in pursuing maximum return and minimum risk under certain return conditions.

Authors: Feng Yuan
Published: May 2023

Due to the impact of the global COVID-19 pandemic, the international rental market has been affected by various degrees of economic and environmental impacts, resulting in large volatility since 2020. Among the several countries and regions, including North America, Asia, and Europe, their developed rental market business sizes all show different downward trends. However, the rental business in China has been on the rise, because the country's epidemic prevention and control efforts have been successful. From 2020 to 2022, the proportion of China's rental business in the world has steadily increased, and China has gradually become an emerging force in the international rental market. However, the landscape of the world's rental industry has not changed and the overall structure and nature of the world's rental market has not fundamentally changed. This paper analyzes the latest changes in the international rental market and puts forward corresponding suggestions based on the data of penetration rate and market share of important countries in the international market in the past three years.

Approaches to Assess Venture Capitals’ Risk, Feasibility, and Its Impacts on the Performance of Firms in China
Authors: Qian Zhenyu
Published: May 2023

Venture capitals (VCs) are the type of investment that are featured for its high risk and high returns. Nowadays VCs have been more and more commonly employed in firms’ strategies, in that venture capitalists gradually realize the benefits of doing so and are underpinned by the advanced technology as well as economic growth. This article examines the VCs’ risk, feasibility, and impacts on firms based upon three models. The article reviews 5 papers and discusses the research methods used for the assessment of VCs. The review of the three models, the Propensity Score Matching method (PSM), the Cox Proportional Hazard model (CPH), and the Fuzzy Synthetic Evaluation model (FSE), summarizes the various impacts of VCs on firms in China. In this paper, it is noticed that not only the risk and returns of VCs have to be paid attention to, but also the reputation of firms and the time in which firms invest VCs should also be considered.

Analysis the Special Nodes of E-commerce Platforms Based on the Background of "Double Eleven" Marketing
Authors: Wang Yilin
Published: May 2023

As a result of the recent outbreak, it would appear that the "Double Eleven" shopping festival has entered its mature phase, with consumer behaviors gradually becoming more rationalized and customer enthusiasm gradually decreasing. The purpose of this study was to analyze how Pinduoduo can reform and improve its marketing campaigns in order to better boost the desire of people to buy and move the economy forward in the midst of a slump. This study came to the conclusion that consumers' willingness to buy will be influenced by quality-assured and diverse products, cost-effective prices, easy-to-play and easily accessible offers, and close user relationships. On the other hand, the proliferation of newly emerged content platforms and live e-commerce will further occupy the e-commerce platform market and squeeze users' space. As a consequence of this, the only way to improve a company's reputation and brand image, as well as improve the process of corporate transformation and upgrading, and increase consumer stickiness, is to consistently attract big brands, expand digital operations, and serve a diverse range of consumer wants.
The Rising Impacts of the COVID-19 Pandemic and Ukraine Conflict: Inflation and Energy Crisis
Authors: Wang Zile , Wei Yi
Published: May 2023

This paper examines the inflation and energy crises in various countries during the epidemic and the Russia-Ukraine conflict. This paper focuses on the fluctuations of inflation and energy CPI indices in the European market, the US market, and the Chinese market during the epidemic and under the influence of the Russia-Ukraine conflict. Through research and studies, it found that the Russian-Ukrainian conflict was the direct cause of high inflation in the European economy and the epidemic had less impact on the European market. However, the situation in the US market is very different. The US market was mainly affected by the epidemic and was less affected by the Russian-Ukrainian conflict. Finally, the epidemic had a relatively large impact on the inflation rate in China and the Russian-Ukrainian conflict had a minor impact on the Chinese market. Ukraine conflict may contribute to the dangerous divergence between advanced and emerging market and developing economies. More broadly, it risks fragmenting the global economy into geopolitical blocs with distinct technology standards, cross-border payment systems, and reserve currencies.
Celebrity Media Effects: the Power of the Stars
Authors: Peng Yixuan
Published: May 2023

With the gradual popularization of the Internet and the types of media increasing, the appeal of a variety of stars - who are in a series of TV shows, in all kinds of movies, or singing and composing songs - is also increasing. The Internet has made their works more widely available, which means their influence on the public has expanded, resulting in gaining a large number of "fans". The savvy commercial companies seize the opportunity and hire those celebrities to endorse their products, hoping to utilize the "star effect" to turn fans into consumers of their products. Based on the concepts of "star effect" and "precision marketing", this paper explores the relationship among stars, fans and commercial companies by analyzing relevant cases. The research finds that stars may not always bring positive feedback to commercial companies, stars' fans may not always bring positive benefits to commercial companies, and commercial companies may not recover the cost of hiring stars from their fans. that is to say, "star effect" is not the inevitable result of celebrity endorsement.

A study on how to link OKRs model with incentive compensation
Authors: Chen Zewei
Published: May 2023

As an emerging tool of Management by Objectives, the Objective-Key Results (OKRs) model has been widely used in management practice in recent years; however, the academic community has not reached a consistent conclusion on whether OKRs should be linked to incentive compensation. The author argues the benefits of the linkage in terms of the common ground of the two concepts, the importance to employees' sense of fairness, and the strengthening effect on key indicators. From a practical point of view, the author believes that OKRs need to take advantage of KPIs in the process of application, using employees' personal KPIs as the basis for determining goals and employees' self-evaluation and score correction as indicators to measure the degree of completion, and the combined KPI+OKR model formed will be able to realize the linkage with incentive pay and play an important reference role in employees' future merit evaluation and promotion. Therefore, this paper proposes a scheme by elaborating the theory, focusing on two aspects, namely goal setting and result measurement, to optimize and improve the operation process of OKRs; and supplemented with practical cases to fully illustrate the promotion of OKRs to employees' initiative and the guiding effect of OKRs on employees' self-growth.

Authors: Kiryukhina L.D. , Kokorina E.V. , Gavrilov P.V. , Savin I.B. , Yablonskiy P.K.
Published: May 2023

Introduction. The study of the diffusion lung capacity (DLCO) shows the conditions of oxygen transport from the alveolar air into the blood of the pulmonary capillaries. The features of changes in the parameters of pulmonary gas exchange in patients with pulmonary tuberculosis (PT) have not been sufficiently studied. Materials and methods. 374 patients with verified PT underwent a study of the pulmonary function including DLCO and the transfer coefficient of carbon monoxide DLCO/VA, computed tomography and perfusion scintigraphy of the lungs. Results. The pulmonary gas exchange depends on the duration of PT, the volume of a specific lesion, the severity of disorders of pulmonary perfusion, including in the lung without foci of tuberculous lesions. In 23% of patients, a decrease in the transfer coefficient was observed at normal DLCO values, which indicates significant alveolar-capillary damage. Conclusion. When assessing pulmonary gas exchange in patients with pulmonary tuberculosis, it is necessary to estimate not only DLCO, but also on the transfer coefficient of carbon monoxide - DLCO/VA.

Authors: Kondakova T.N. , Kovaleva R.G. , Elkin A.V. , Tyarasova K.G. , Khorkova S.M.
Published: May 2023

Clinical, radiological, and laboratory data of 62 patients with respiratory tuberculosis were studied with the purpose of comparative analysis of clinical efficacy of Glutoxime and Tubosan and evaluation of efficiency of the empirical approach in drug selection. Three groups of patients were formed: the 1st group - 20 patients who received Glutoxim along with anti-tuberculosis drugs. Group 2 - 23 patients (Tubosan), Group 3 – control, 19 patients (only anti-tuberculosis drugs). Empirical approach to the choice of pathogenetic drugs has a limited positive effect on the efficacy and tolerability of etiotropic therapy. In the conditions of forced polypragmasy, the prescription of drugs should be justified by modern highly informative criteria, not being limited only by clinical indications.
Energy transition under mineral constraints and recycling: A low-carbon supply peak
Authors: Chazel Simon , Bernard Sophie , Benchekroun Hassan
Published: May 2023

What are the implications of primary mineral constraints for the energy transition? Low-carbon energy production uses green capital, which requires primary minerals. We build on the seminal framework for the transition from a dirty to a clean energy in Golosov et al. (2014) to incorporate the role played by primary minerals and their potential recycling. We characterize the optimal paths of the energy transition under various mineral constraint scenarios. Mineral constraints limit the development of green energy in the long run: low-carbon energy production eventually reaches a plateau. We run our simulations using copper as the limiting mineral and we allow for its full recycling. Even in the limiting case of a 100% recycling rate, after five to six decades green energy production is 50% lower than in the scenario with unlimited primary copper, and after 30 decades, GDP is 3–8% lower. In extension scenarios, we confirm that a longer life duration of green capital delays copper extraction and the green energy peak, whereas reduced recycling caps moves the peak in green energy production forward.

La influencia al incorporar arcilla expandida en el diseño de mezcla y resistencia del concreto liviano de alto rendimiento en el Distrito de Lircay – Angaraes – Huancavelica, al efecto, la pregunta de nuestra investigación es la siguiente: ¿De qué manera influye la incorporación de arcilla expandida en la resistencia de concreto liviano de alto rendimiento en el Distrito de Lircay – Angaraes - Huancavelica?, La influencia al incorporar arcilla expandida en porcentajes 5%,10%,15% y 20%, en el diseño de mezcla influye significativamente en la resistencia del concreto liviano de alto rendimiento la trabajabilidad y la homogeneidad se mantienen a medida que se aumenta la arcilla expandida obteniendo un asentamiento de 6 a 2.5 cm. dentro de los límites de una consistencia balanceada. De los resultados obtenidos a los 28 días de edad de f’c=210 kg/cm² y f’c=280 kg/cm², se concluye que los concretos con adición de Arcilla en sus diferentes proporciones son inferiores al concreto patrón, superando a la resistencia requerida f’c=210 kg/cm² y f’c=280 kg/cm². Con respecto del peso unitario del concreto fresco para f’c=210kg/cm2 y f’c=280kg/cm2, se deduce que su peso vario significativamente en una mínima cantidad.

Se puede concluir que la arcilla expandida es aplicable para la elaboración de concretos debido a sus resistencia y ligereza, pudiendo reducir las cargas sobre estructuras como losas y muros. También puede ser aplicable en rellenos para instalaciones de tuberías reduciendo las proporciones y las cargas sobre las mismas.

Authors: Snehith Madduri
Published: May 2023

This paper effects of cigarette smoking on nerves and oral health. Smoking adversely affects the trigeminal, lingual, and nasopalatine nerves, leading to taste and smell disturbances, xerostomia, and decreased somatosensory function. Additionally, cigarette smoke contains harmful chemicals such as carbon monoxide, tar, benzene, arsenic, and formaldehyde, which contribute to the development of chronic diseases such as lung cancer, COPD, stroke, and heart disease. Smoking also impedes oral health by negatively impacting wound healing and promoting bad breath, staining, and aging. The paper underscores the critical need for smoking cessation interventions and public education campaigns to raise awareness about the deleterious effects of cigarette smoking. Overall, prioritizing smoking cessation as part of a comprehensive approach to promoting healthy nerves and oral health is paramount. Keywords: Cigarette smoking, nerves, somatos, health effects, periodontal diseases, slow response, xerostomia.

Authors: Shahrun Nur Shahira Bte , Ramasamy Suganthi , Yen Yuen Yee
Published: May 2023

Environmental, social, and governance (ESG) criteria are used by most corporations to achieve and maintain the best management quality. Thus, implementing ESG might assist firms in Malaysia to improve their corporate performance. The purpose of this research is to analyze the effect of ESG on corporate performance in terms of the value of Malaysian listed firms. A total of 45 companies listed on Bursa Malaysia that have complete ESG data from 2011–2021 were selected from Bloomberg’s ESG database. Corporate value was measured using three indicators – return on assets (ROA), return on equity (ROE) and Tobin’s Q. According to the results, the ESG scores have an insignificant positive influence on ROE and Tobin’s Q. However, the ESG scores have a negative but insignificant impact on ROA. The individual Environmental score has a negative impact on ROA but a positive impact on ROE and Tobin’s Q. Meanwhile, Social on its own has an insignificant negative impact on all variables, and Governance has a positive but insignificant impact on all variables. Based on the inconsistencies between the results of this study and those of previous research, the conclusions on whether ESG criteria promote business value and performance cannot be reached. ESG practices have become increasingly important, not only for policymakers but for governments and stakeholders. Hence, the outcome of this study will be useful for the government to reduce costs and implement policies to improve corporate performance in Malaysia.

De ontwikkeling van de Meting Veiligheidsperceptie

DCMR ontwikkelde samen met wetenschappers van Universiteit Leiden en TU Delft, ondernemingsvereniging Deltalinqs en een grote raffinaderij als pilotbedrijf, de Meting Veiligheidsperceptie (MVP). Het doel was een instrument te ontwikkelen dat een representatief beeld geeft van de prioriteit van veiligheid in de organisatie, efficiënt en eenvoudig uit te voeren is en draagvlak heeft onder bedrijven. De resultaten houden deelnemende bedrijven een spiegel voor: Creëren zij de juiste randvoorwaarden voor een veilige werk- en leefomgeving? De uitkomsten vormen het beginpunt van een dialoog gericht op leren en verbeteren zowel binnen het bedrijf als tussen toezichthouder en bedrijf.
‘Tone at the top’ als maatstaf voor compliance?

‘Tone at the top’ als maatstaf voor compliance?

De gedachte is dat het bestuur van een organisatie via de ‘tone at the top’ (TATT) grote invloed heeft op de gedragingen van de organisatie. Uit ons onderzoek blijkt dat de mate waarin het bestuur zorgt voor een heldere communicatie van de houding binnen de organisatie – onder andere aan de hand van heldere en realistische (fiscale) doelstellingen – positief samenhangt met compliance. Voor externe toezichthouders is dit een indicatie dat de expliciete vastlegging en het delen van de strategie van de organisatie een belangrijke rol kunnen spelen in het zicht krijgen op de TATT. Aanvullend lijkt het mogelijk om de TATT te beïnvloeden via op vertrouwen en samenwerking gebaseerde toezichtstrategieën, zoals het horizontaal toezicht.
Klimaattransitie vraagt om maatschappelijk verantwoord leiderschap

Klimaattransitie vraagt om maatschappelijk verantwoord leiderschap

De gevolgen van klimaatverandering worden steeds tastbaarder. De druk op bestuurders van organisaties om maatschappelijk verantwoord leiderschap te tonen, groeit. Hiermee bedoelen we dat van bestuurders wordt verwacht dat zij niet alleen zeggen dat zij de klimaattransitie belangrijk vinden, maar vervolgens ook die goede intenties kunnen omzetten in daadwerkelijk gedrag dat hieraan bijdraagt. Voor het stimuleren van maatschappelijk verantwoord leiderschap vanuit extern toezicht biedt de psychologische benadering verschillende mogelijkheden. Namelijk: creëren van een risicobewuste houding, benutten van de sociale norm en versterken van het geloof in eigen kunnen. Door te experimenteren met deze manieren van gedragsbeïnvloeding kunnen externe toezichthouders hun bijdrage aan de klimaattransitie vergroten.

Tegengaan van bestuurlijk verval in de semipublieke sector

Bij woningcorporaties, onderwijs-, cultuur- en zorginstellingen zijn het afgelopen decennium verscheidene ervaren bestuurders van hun voetstuk getuimeld. Vaak zaten krachtige bestuurders al lang op hun plek en kregen zij in de loop der tijd steeds minder tegenspel. Hoe kunnen interne en externe toezichthouders bestuurlijk verval eerder signaleren en tegengaan? Meike Bokhorst deed samen met Sjors Overman onderzoek naar zo’n veertig misstanden in de semipublieke sector. Ze deden literatuurstudie, analyseerden rapporten van incidenten, spraken met secretarissen, toezichthouders en bestuurders en deden een survey onder bestuurders. Het onderzoek laat zien hoe toezicht kan meegroeien met de bestuurskracht. Als de ervaring van bestuurders na verloop van tijd toeneemt, moet ook het toezicht zich blijven versterken, en waar nodig van rol veranderen. Zo blijven macht en tegenmacht in balans.
Filling the Third Circle with Interdisciplinary Lesson Planning: A Case
Study of Pre-Service Teachers
Authors: Steede Garrett , Swenson Rebecca D. , McKay Troy D.
Published: May 2023

The three-circle model of agricultural education focuses
on the importance of in-class instruction, supervised agricultural experiences, and FFA
involvement. The agricultural communications career pathway is available to students
through agricultural communications supervised agricultural experiences (SAE) programs
and career development events within FFA. However, specific curriculum that teaches
agricultural communications in the classroom is not readily available. The purpose of
this qualitative case study was to examine the interdisciplinary lesson planning and
integration process of pre-service teachers with focus on opportunities and limitations
to teaching communication in the agriculture, food, and natural resources (AFNR)
curriculum. In this case study, four pre-service teachers worked with agricultural
communications faculty to develop communication curricula and lesson plans to be
incorporated into high school AFNR classrooms. These pre-service teachers developed
interdisciplinary lessons prior to student teaching and, when appropriate, used these
lessons in their classrooms. While current research regarding teaching science in the
AFNR curriculum is ongoing, the literature is silent regarding teaching social sciences
such as communication in the AFNR curriculum. These pre-service teachers want more
opportunities to develop interdisciplinary lessons. They believe teaching communication
skills while tying them to the content area can improve student knowledge, retention,
and engagement in the learning process while exposing them to the agricultural
communications career pathway.
Why Youth Leave 4-H After the First Year: A Multistate Study

Enrollment in US youth development programs is decreasing
annually. Research has shown that youth in the 4-H youth development program experience
a broad range of positive youth development outcomes, including greater community
contributions, healthier choices, higher academic competence, critical life and
leadership skills such as problem-solving, goal setting, communication, responsibility,
and a sense of belonging and purpose. Finding ways to retain youth in the program for
more than a year or two can profoundly impact society due to the skills developed and
opportunities provided to youth in 4-H. The purpose of this study was to understand why
youth might leave the 4-H program after one year of involvement. Using data from a
multiyear, multistate study of first-year 4-H members, we examined why youth might leave
the program and what first-year experiences correlate with youth dropout. Quantitative
and qualitative survey data suggest that youth leave the program because of challenges
related to belonging, welcoming, time, communication, interactions with adults, and
overall organization. These findings can provide youth development faculty, programming
staff, and volunteers with directions for improving the program to retain more youth.
