The family planning program is one of the most important national development programs in the context of realizing a prosperous Indonesian family. One of the main tasks of family planning (KB) development towards the development of a prosperous family is through birth control efforts that can be done by using contraception. Rapid population development will affect life in society. To prevent this problem, the government held a family planning program. The use of injectable contraception is the most popular method by the community to date. The purpose of this community service activity is so that the community can increase knowledge about injectable contraceptives as pregnancy prevention protection. Counseling is carried out using flipcharts. The population and sample of this service are couples of childbearing age as many as 15 people. This activity was carried out at the Aek Bayur Village Hall. The results of this community service were enthusiastically received by the participants as seen from the many people who asked about information on injectable contraceptives, installation procedures, contraindications, advantages and disadvantages of using this contraceptive injection. It is recommended that outreach activities in increasing knowledge about injectable contraceptives can be carried out regularly with a more frequent frequency and the range of information dissemination can also be expanded to families in general so that everyone, families and the community better know, understand about injectable contraceptives as pregnancy prevention protection.

Abstract. The ability of regional air quality models to skilfully represent pollutant distributions throughout the atmospheric column is important to enabling their skilful prediction at the surface. This provides a requirement for model evaluation at elevated altitudes, though observation datasets available for this purpose are limited. This is particularly true of those offering sampling over extended time periods. To address this requirement and support evaluation of regional air quality models such as the UK Met Offices Air Quality in the Unified Model (AQUM), a long-term, quality assured, dataset of the three-dimensional distribution of key pollutants has been collected over the southern United Kingdom from June 2019 to April 2022. This sampling period encompasses operations during the global COVID-19 pandemic, and as such the dataset serves an additional application in providing a unique resource with which to explore changes in atmospheric composition associated with reduced emissions during this period. Measurements were collected using the Met Office Atmospheric Survey Aircraft (MOASA), a Cessna-421 instrumented for this project to measure gaseous nitrogen dioxide, ozone, sulphur dioxide and fine mode (PM2.5) aerosol. This paper provides a technical introduction to the MOASA measurement platform, flight strategies and instrumentation. The MOASA air quality dataset includes 63 flight sorties (totaling over 150 hours of sampling), the data from which are openly available for use. Example case studies using data from these sorties are presented, which include an analysis of the spatial scales of measured pollutant variability, initial work to evaluate performance of the AQUM regional air quality model, and an introduction to the vertical structure of pollutants observed during repeated flight patterns over Greater London, including during the COVID-19 impacted period.
Seasonal forecasting skill for the High Mountain Asia region in the Goddard Earth Observing System

Published: February 2023

Abstract. Seasonal variability of the global hydrologic cycle
directly impacts human activities, including hazard assessment and
mitigation, agricultural decisions, and water resources management. This is
particularly true across the High Mountain Asia (HMA) region, where
availability of water resources can change depending on local seasonality of
the hydrologic cycle. Forecasting the atmospheric states and surface
conditions, including hydrometeorologically relevant variables, at
subseasonal-to-seasonal (S2S) lead times of weeks to months is an area of
active research and development. NASA's Goddard Earth Observing System
(GEOS) S2S prediction system has been developed with this research goal in
mind. Here, we benchmark the forecast skill of GEOS-S2S (version 2)
hydrometeorological forecasts at 1–3-month lead times in the HMA region,
including a portion of the Indian subcontinent, during the retrospective
forecast period, 1981–2016. To assess forecast skill, we evaluate 2 m air
temperature, total precipitation, fractional snow cover, snow water
equivalent, surface soil moisture, and terrestrial water storage forecasts
against the Modern-Era Retrospective analysis for Research and Applications,
Version 2 (MERRA-2) and independent reanalysis data, satellite observations,
and data fusion products. Anomaly correlation is highest when the forecasts
are evaluated against MERRA-2 and particularly in variables with long memory
in the climate system, likely due to the similar initial conditions and model
architecture used in GEOS-S2S and MERRA-2. When compared to MERRA-2, results
for the 1-month forecast skill range from an anomaly correlation of
Ranom=0.18 for precipitation to Ranom=0.62 for soil moisture.
Anomaly correlations are consistently lower when forecasts are evaluated
against independent observations; results for the 1-month forecast skill
range from Ranom=0.13 for snow water equivalent to Ranom=0.24
for fractional snow cover. We find that, generally, hydrometeorological
forecast skill is dependent on the forecast lead time, the memory of the
variable within the physical system, and the validation dataset used.
Overall, these results benchmark the GEOS-S2S system's ability to forecast
HMA hydrometeorology.

ASSESSING EFFICIENCY OF GPS EPHEMERIDES IN DIFFERENT REGION USING PRECISE POINT POSITIONING
Authors: Lee H. S. , Wan Aris W. A. , Musa T. A. , Ahmad A.
Published: February 2023

Abstract. Precise Point Positioning (PPP) is a technique that process Global Positioning System (GPS) observation that can achieve sub-decimetre accuracy. Precise ephemerides that contain satellite clock and position plays a vital role in minimising orbital and clock error in PPP. This study hypothesize that the efficiency of ephemerides varies across region, influenced by the density of stations involved in generating the ephemerides. GPS observations from stations in five different regions were processed using PPP technique by using RTKLIB. Four types of ephemerides were used namely broadcast, ultra-rapid, rapid, and final ephemerides during the processing of each station. Root-mean-squared error (RMSE) of 3D error of the PPP solution for the stations in each region is quantified. Among the five regions selected, Europe has the lowest RMSE of 155.67 cm, 27.93 cm, 27.38 cm and 27.06 cm for broadcast, ultra-rapid, rapid, and final ephemeris respectively. This high accuracy can be attributed to the density of International GNSS Service (IGS) stations in Europe that are available for the generation of ephemerides. Position Dilution of Precision (PDOP) was also found to contribute to the accuracy of PPP solution in a region, whereby a low PDOP often promises higher positioning accuracy. More regional stations are suggested to be involved in the generation of ephemerides to improve the efficiency of ephemerides in that region.
3D BUILDING MODELS DEVELOPMENT BASED ON DATA FUSION – CURRENT STATUS
Authors: Mutiarasari W. M. , Abdul Rahman A.
Published: February 2023

Abstract. For the past years, a better and complete 3D building model has been intensely studied. To get a 3D building model as desired, it is known to use data fusion which is a technique of 3D dataset combination. Data fusion is conducted to overcome the limitations of each measurement technique in obtaining data. This paper aims to show the status of 3D building models development that is generated from two or more datasets by using data fusion technique. From several works of data fusion, it is observed the development of data fusion related things like various technologies, methods, and accuracy. The technology used varies for data fusion, for both air and ground based measurements. Technologies such as Terrestrial Laser Scanning (TLS) and close-range photogrammetry are the most appropriate surveying methods to generate accurate and high-resolution models. Meanwhile, recent technology of mobile laser scanning makes scans more quickly and offers more convenience to obtain data in a difficult area. Furthermore, mobile laser scanning has higher completeness data than photogrammetry data. For future work, mobile laser scanning data is be considered to use in data fusion. In term of accuracy, several works agreed that data fusion is a better way to have more complete 3D building models with high accuracy. Related to data processing of data fusion, most of algorithms have disadvantage in accelerating the data fusion time. Therefore, an algorithm to shorten the processing time needs to be created.
VERTICAL ACCURACY EVALUATION OF THE FOREST AND BUILDINGS REMOVED COPERNICUS DEM (FABDEM) OVER THE PHILIPPINES
Authors: Santillan J. R.
Published: February 2023

Abstract. This study evaluated the accuracy of the Forest And Buildings removed Copernicus DEM (FABDEM) over the Philippines. The evaluation was conducted at the country and island levels using 17,013 Geodetic Control Points (GCPs) partitioned into 3 independent sets. Results suggest that the FABDEM generally underestimates terrain elevation in the Philippines, as exemplified by a mean error of −1.44 m which is the average among the three sets of the GCPs used. Negative errors are primarily dominant in Luzon Island in the northern part of the Philippines, and positive errors are prevalent in the Visayas and Mindanao islands. At the country level, the DEM has an average Root Mean Square Error (RMSE) of 4.74 m and average linear errors of 7.80 m and 9.80 m at 90% and 95% confidence levels, respectively. At the island level, the DEM's accuracy varies, with some islands having RMSEs as low as 3.03 meters and as high as 5.80 m. This DEM is also most accurate at elevations less than 100 m and slopes less than 2 degrees. Care must be taken when applying the FABDEM in an archipelagic country like the Philippines due to several factors, such as the general tendency of this DEM to underestimate elevations, the dominance of negative errors in the northern part of the country, the differences in accuracies of elevations from one island to another, and the pronounced influence of elevation and slope to its accuracy. Nevertheless, the FABDEM is one of the most accurate among several freely available global DEMs covering the Philippines. Its accuracy in Mindanao Island is comparable to AW3D30 and superior to SRTM DEM.
SPATIAL DOWNSCALING OF GPM IMERG V06 GRIDDED PRECIPITATION USING MACHINE LEARNING ALGORITHMS
Authors: Sathianarayanan M. , Hsu P.-H.
Published: February 2023

Abstract. According to recent studies, Remote sensing data plays a significant role in filling gaps in the poor gauge station, particularly at high elevations and with complex underlying surface features. In order to provide high-resolution precipitation estimates over the poor gauge and with complex terrain areas, downscaling low-resolution satellite precipitation estimates using various environmental variables. In this paper, we tried to downscale the GPM IMERG V06 with a resolution of (0.1° × 0.1°) nearly 10km to (1km × 1 km) using four machine learning algorithms namely, Decision Trees, Multiple Linear Regression, Support Vector Regressor and random forest. Vegetation indices Normalized difference in vegetation index (NDVI), Topography, Land Surface Temperature (LST), and latitude and longitude. This framework can downscale the 0.1° resolution of the GPM IMERG precipitation product to 1 km, by determining the importance of features, and automatically optimizing the model parameters. Additionally, ground recorded data from rain gauge stations have validated downscaled precipitation products. Spatial downscaling can generally increase the accuracy of GPM IMERG gridded precipitation data and results reveal that spatial downscaling is an acceptable way of investigating the precipitation over Taiwan.

Abstract. Currently there is a public awareness to protect the environment especially forest ecosystems and the forest fire dilemma has become a topic of intense research around the world. In this setting, this study evaluates forest fire susceptibility (FFS) in northern Morocco using three geographic information system (GIS) based on machine learning algorithms: XGBoost (XGB), Random Forest (RF), and Support Vector Machine (SVM). To this effect, a Geographic Information System (GIS) database was developed involving ten independent causal factors (elevation, aspect, slope, distance to roads, distance to residential areas, land cover, normalized difference vegetation index (NDVI), rainfall, temperature and wind speed) and 345 fire pixels. The 345 pixels were split into two sets for training (70%) and validation (30%) and the spatial relationships between factors affecting FFs and fire pixels was analyzed using XGB, RF, and SVM models to generate the FFS maps. The effectiveness of the models was evaluated using the receiver operating characteristic curve, the area under the curve (AUC), and several statistical measures. The results of the three models hinted that XGBoost had the highest performance (AUC = 0.856), followed by RF (AUC) = 0.827), and SVM (AUC = 0.803) in the forecasting of the forest fire. The resulting FFS maps areas can provide crucial support for the management of Mediterranean forest ecosystems and can enhance the effectiveness of planning and management of forest resources and ecological balances in these areas.

Una revisión preliminar de estudios anteriores ha evidenciado que el método utilizado para involucrar a la comunidad en las artes suele estar muy mal articulado. Además, las evaluaciones y reflexiones formales sobre los proyectos de participación artística comunitaria son muy escasas. Por lo tanto, este estudio pretende explorar el método de cocreación del arte comprometido con la comunidad con comunidades seleccionadas en Kampung Muhibbah, Kuching, Sarawak, Malasia. El objetivo del debate es destacar cómo la cocreación puede ofrecer un enfoque participativo que contribuya a elevar la calidad de vida tanto para los profesionales del arte como para los que no lo son. La investigación se llevó a cabo con un método mixto que utilizó un proyecto de cocreación como estudio de caso para la recopilación de datos, mediante entrevistas y observaciones de los participantes en un método cualitativo y una puntuación de evaluación del bienestar en un método cuantitativo. Los resultados mostraron que el proyecto de cocreación podía establecer buenas interacciones dentro de la comunidad a través de actividades artísticas y posteriormente elevar su calidad de bienestar. Una comprensión más profunda del método de cocreación con la participación de la comunidad puede poner en tela de juicio la práctica artística participativa convencional. La exploración del método de cocreación a través del arte como medio ha contribuido ampliamente al conocimiento de la práctica de la cocreación en el compromiso de la comunidad para elevar el bienestar.
Following Hillary Clinton and Donald Trump: A dissection of their tweets in the 2016 U.S. presidential election
Authors: Akman Varol , Yenimol Mehmetali Semi
Published: February 2023

In this work, the tweets of Donald Trump and Hillary Clinton in the 2016 U.S. presidential campaign are studied and analyzed from a language-based perspective. The tweets are divided into two batches. The first is from the earliest announcement of candidacy until the last announcement of nomination of candidates. The second is between the end of the first interval and the inauguration of Trump. Readability statistics of tweets are computed and the Scholastic Aptitude Test (SAT) words — subject of much cramming by test takers — in the tweets are analyzed, as well as Ogden’s Simple English words. Some of the readability indexes exhibit minor differences, implying that Clinton’s tweets are more readable whereas the other readability indexes are proximate for the candidates. Clinton’s use of unique SAT words is found to be denser than Trump’s, indicating that employing such words less might be wiser for political campaigns. Simple English analysis does not tell of a noticeable difference. Syntactic Dependency Distance of tweets and Integrative Complexity of tweets were also analyzed but no significant difference for the two candidates was discerned.
How does technostress during a pandemic affect employee attrition in IT/ITeS industries? Insights from India
Authors: Batta Anuj , Kar Arpan K.
Published: February 2023

Many organizations utilize information and communication technologies (ICTs) to maximize the efficiency and effectiveness of their employees in order to achieve best possible resource utilization. With many salient positive outcomes and benefits for organizations, the use of ICTs also imposes a risk of increased stress for employees, referred to as ‘technostress’. This study tests a model to identify the relationship between technostress and employee attrition in information technology (IT) companies in India during a pandemic which in turn escalated dependencies on ICTs, creating stress among employees. Multiple constructs have been utilized using the ‘person-environment fit’ model for this study. Primary data collection with stratified sampling was administered on a multinational IT firm. Statistical tests were performed and inferential model was developed. The findings support the model, providing insights into the role, significance, and ranking of six constructs in employee attrition. The outcome clearly suggests the presence of technostress due to ICTs and its effects on employee attrition during a pandemic.

Published: February 2023

In this study, we examined online conversations on Twitter about the Russia-Ukraine War and investigated differences between bots and non-bots accounts. Using ‘Russia’ and ‘Ukraine’ as keywords, we employed a Twitter API to collect data from 17 February to 18 March on Twitter. We obtained a large dataset of over 3.7 million tweets generated by about one million distinct accounts. We then analyzed one percent of the data using interval sampling for bot detection and found that about 13.4 percent of the accounts were social media bots, responsible for about 16.7 percent of the tweets. We examined the difference between bots and non-bots regarding online conversations on the Russia-Ukraine War through account analysis, textual analysis, and interaction analysis. The results show that bots exist on both sides, bots from the Ukrainian side contributed a louder voice while bots on the Russian side demonstrated more effective communication. In addition, there were differences and similarities between bots and non-bots in the behavior of online conversations, but the difference seemed to be relatively weaker than those found in previous studies.

Published: February 2023

O presente artigo discute a inserção da abordagem Ciência-Tecnologia-Sociedade (CTS) na formação inicial de professores de Química como possibilidade de articulação dos conhecimentos químicos com questões sociais e tecnológicas nas práticas pedagógicas. A abordagem da pesquisa é qualitativa e baseou-se na análise documental de sequências didáticas elaboradas por licenciandos em Química. São discutidas neste artigo as potencialidades e limitações das sequências didáticas (SD) construídas com base na abordagem CTS. A análise das SD baseou-se em um instrumento elaborado por Silva e Marcondes (2015) para avaliação de unidades didáticas com enfoque CTS. Neste trabalho são analisadas seis sequências didáticas e os resultados indicam que as SD apresentam aspectos sociais e científicos de forma satisfatória e inter-relacionada, no entanto, a tecnologia não é explorada na maior parte delas. Foram identificados como potencialidades nas SD a abordagem por temas, a retomada da questão social ao final da SD, a opção por assuntos controversos e problemáticas contemporâneas e contextuais. As limitações evidenciadas são a abordagem marcadamente conceitual, disciplinar e a ausência da discussão de questões tecnológicas. Com esses elementos se reforça a importância de espaços de discussão e reflexão acerca de abordagens como a perspectiva CTS na formação inicial de professores de Ciências e Química.

Aim: To study the spectrum of Pituitary tumours, their presentation, treatment and compliance with follow-up. Study design: Mixed retrospective and prospective study Place and duration of study: Medicell Institute of Diabetes, Endocrinology and Metabolism and Jinnah Postgraduate Medical Centre Karachi from 1st January 2012 to 31st July 2022. Methodology: One hundred and seventy three cases of pituitary tumours, were enrolled. Data regarding age, gender, duration of disease, symptoms, mode of treatment administered and compliance with the follow-up instructions was retrieved. Results: The mean age was 36.4±10.6 years. Female predominance was seen in 97(56.1%). Of the 136 married patients, subfertility was seen in 48(36.3%). Headache was observed in 164(94.8%) of patients. Prolactinoma was the lead tumour comprising of 76 cases (43.9%), followed by non-secretory tumours 47(27.2%), and acromegaly 43(24.9%). Other rare disorders including Cushing’s disease, craniopharyngioma and gonadotropinoma were also seen. Cabergoline was prescribed in 136 (78.6%) cases. Transsphenoidal surgery (TSS) was done in 74(42.8%) of patients. Out of 97 female patients, 38(39.2%) had persistent amenorrhea post-treatment, while this data was not available for 40(41.2%) of these women, who were lost to follow-up. The difference between mean prolactin levels prior and after the treatment (1390.048±2646.986 versus 116.360±163.369) were found to be statistically significant p<0.001). Similarly, IGF-1 levels were significantly improved post treatment indicating tumour stability. Moreover, the level of mean FT4 post-treatment was 1.64, reflecting adequate replacement. Conclusion: Majority of the patients had improvement post-treatment in pituitary tumour symptoms including vision, headache and sexual function. Failure to attend for follow-up for tumour stability, control of excess hormone, and pituitary hormone replacement was seen in a large number of patients in this study. This requires careful consideration of different strategies to ensure better long term care in pituitary tumours.

Published: February 2023

Background: Piperine is an alkaloid present in black pepper. It causes increase in diameter of Graafian follicles when given to adult female albino rats thus leading to decreased fertility. Aim: To assess the harmful effects of piperine on ovaries of adult female albino rats on diameter of Graafian follicles. Study design: Experimental Study. Place and duration of study: Anatomy Department, Shaikh Zayed PGMI, Lahore from 1st August 2013 to 31st January 2014. Methodology: Thirty female rats were randomly separated into three equal groups A, B and C, each having 10 animals. Group A was control and did not receive any medication except for normal saline at a dose of 10ml/kg body weight/day by orogastric tube for 30 days. Group B and C received piperine suspended in saline by orogastric tube, at a dose of5mg/kg/day and 10 mg/kg/day respectively for 30 days. After 30 days of experiment, the rats of all three groups were euthanized and ovaries were removed by dissection and then fixed in 10% formalin. With rotary microtome, 4-5μm sections were prepared and stained with hematoxylin and eosin solutions. Results: The Graafian follicle in ovaries of rats in group B showed increased diameter as compared to control group A. The diameter of Graafian follicles of group C was greater than of group B. In both groups comparison was made, the p-value was less than 0.001. Conclusion: Piperine administration in female adult albino rats showed significant increase in size of Graafian follicle which is likely to produce polycystic ovarian syndrome (PCOS) and in this way hamper fertility in females during child bearing age.

The results obtained from the two procedures were recorded in a data collection form by a third-year emergency medicine assistant. The data was analyzed by SPSS 23 software.

Results: Overall, 129 patients were enrolled, the mean age of whom was 56.18 ± 16.33.68 years. There were 68 males (52.7%) and 61 females (47.3%) among the participants. The positivity or negativity of the data retrieved from CUStwo-point and DUS was assessed by the McNemar test, and a P-value of 1 indicated the homogeneity of both tests. Compared to DUS (as the gold standard), the sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of the CUStwo-point method were obtained as 97.56%, 95.74%, 97.56%, 95.74%, and 96.9%, respectively. The accuracy of 96.9% of CUStwo-point along with Cohen’s kappa of 0.93 indicated a high agreement between the two ultrasound methods.

Conclusion: CUS seems to be a non-invasive, safe, and accessible method in the emergency department that can provide an appropriate alternative to DUS for the diagnosis of DVT in the lower extremities.
El recurso a la Santa Sede como herramienta de gobierno
Authors: López Lamerain Constanza
Published: February 2023

Este artículo revisa ciertos recursos que los obispos de Chile interpusieron ante la Santa Sede para guiar y fortalecer sus gobiernos diocesanos en el siglo XVII. La instancia de comunicación aquí tratada es la visita ad limina, oportunidad que los obispos de todo el mundo tuvieron para informar al Papa sobre el estado de sus diócesis. En el caso de las iglesias locales americanas, las relaciones con Roma estuvieron afectadas por el Patronato regio, que a pesar de ser una limitante real a una influencia más decisiva de la Santa Sede en América, permitió que circulacen comunicaciones relevantes, sobre todo en materia de normativa canónica. En el caso puntual de Chile además, los obispos ocuparon ese espacio para acusar desobediencias y denunciar transgresiones a su autoridad episcopal. Todo con el afan de mejorar las condiciones de su gobierno y resguardar su posición en el contexto local
Stress, Anticipatory Anxiety, and Mental Health Help-Seeking among Chinese Students in United States at the Beginning of COVID-19: A Thematic Analysis
Authors: Zhou Zixuan
Published: February 2023

The COVID-19 pandemic brought numerous negative effects towards people’s mental health. The current study explored the influence of pandemic on Chinese international students in the U.S. at the beginning of the pandemic. Interview method was used in this study. Interview questions included the influence of pandemic, the influence of panic caused by pandemic, the influence of Asian-hates events, and mental health help-seeking behaviour. As the result, three main themes were narrowed down: stress, anticipatory anxiety, and help-seeking behaviour. The current study found that the most frequent stressor was the risk of infection. The other direct stressors were difficulty of traveling between China and the U.S., negative influence of academic life, and shortage of medical supplies. More indirect stressors were found: worries about Chinese students in the U.S. being infected by parents, worries about discrimination by parents, discriminating experiences of friends, and infection history of friends and of relatives in China. Three anticipatory anxieties were found: getting in touch with others, anti-Asian events, and different strategies to cope with disease. All participants reported no professional help-seeking behaviour. Five of eight participants reported the non-professional help-seeking. Three of eight participants reported they used self-regulation to cope with the stress and anxiety. The results demonstrated the unique experience and coping strategy of Chinese international students. Although they had lived in the U.S. for many years, their coping strategies still identified with Chinese culture. Future study could explore more associations of stress, anxiety, and help-seeking to understand and help Chinese international students better. This study can provide some guidance for future intervention studies and practices regarding the mental health situation of Chinese international students in other countries during the pandemic.

Authors: Jin Shixi , Liu Ning , Ma Chuanyu
Published: February 2023

As the only country in the world to have a fertility policy, the impact of China's fertility policy has been the focus of research by scholars. With several changes in China's fertility policy, some scholars have critically analyzed the employment impact of several fertility policies on women. However, these studies lack a temporal framework to identify the dynamic impact of the policy change on women's employment from a historical perspective. This paper, therefore, explores the impact of changes in China's fertility policies on women's employment through a historical institutionalist research paradigm by collecting the content of fertility policies and their impact on women's employment since the founding of the People's Republic of China. The study shows that fertility issues have become an important determinant of women's employment and that government efforts to support fertility policies are essential in creating a favorable employment environment for women. This paper introduces several changes to China's fertility policy, followed by this paper's analysis of the negative impact of the fertility policy on women's employment. Finally, this paper makes recommendations on how to mitigate the negative impact of fertility policies on women's employment. This paper exposes the contradictory relationship between childbirth and female employment due to the formulation of fertility policies and the lack of supporting governmental action. The analysis also highlights the impact of historical policies on the present and the future.

A hellish gag is a kind of joke that uses other people's disability, tragedy, illness, racial discrimination, war, occupation, death, etc., as a point of humor. This study modeled a mediation test using reading hellish gags, sympathy, and discrimination against blacks, and designed a single-blind experiment to test the null hypothesis.

In addition, It was determined that diminished empathy fully mediated the relationship between reading hellish gags and increased discrimination against blacks, with the mediating effect accounting for 100% of the total effect. Also, some people may be offended and unable to appreciate the humor when the hellish gags involve something related to the group of people comprehending the humor.
