Published: July 2024

Infeksi protozoa usus masih menjadi salah satu permasalahan di dunia, terutama di negara-negara berkembang dan beriklim tropis. Angka insidensi kasus protozoa usus di Indonesia mencapai 10-18%. Infeksi protozoa usus dapat menyerang anak-anak dan orang dewasa (Deza et al., 2018). Di Negara berkembang tingkat pendidikan masih rendah dan iklim tropis merupakan faktor risiko infeksi protozoa usus. Hasil penelitian Charisma dkk. (2020), menyebutkan bahwa pada pemeriksaan sampel feses menunjukkan sebanyak 20,8% positif adanya kista protozoa usus. Didukung oleh penelitian Simatupang et al., (2013) yang melaporkan sebanyak 40% kasus infeksi didominasi oleh protozoa usus daripada cacing usus (STH) pada anak usia SD di Kedung Cowek, Surabaya. Rendahnya pengetahuan masyarakat terkait penyakit parasit masih menjadi salah satu masalah. Dengan demikian, pemberian edukasi kebersihan personal pada mereka menjadi salah satu solusi untuk menurunkan angka infeksi parasit usus (Fransisca et al., 2015). Dengan demikian, peneliti akanmengidentifikasi keberadaan protozoa usus pada sampel feses yang bertujuan untuk mengetahui prevalensi protozoa usus dan gambaran kebersihan personal pada anak usia sekolah dasar di desa Ngingas Barat, kecamatan Krian kabupaten Sidoarjo. Dari hasil pretes dan postes terdapat terdapat peningkatan para siswa dalam menjawab soal dari 2.16 menjadi 3.66. Soal yang paling sulit dijawab oleh siswa adalah nomor 4 yaitu tentang protozoa. Setelah mendapat materi tentang protozoa usus, para siswa mampu menjawab soal nomor 4 pada postes. Peningkatan pengetahuan tentang protozoa usus sebagai penyebab diare diharapkan dapat mengubah sikap dan tindakan para siswa menjadi lebih baik lagi untuk mencegah terjadinya penyakit tersebut. Satu minggu kemudian setelah diadakan kegiatan penyuluhan para siswa dilakukan pemeriksaan Feses lengkap untuk diperiksa adanya infeksi protozoa. Hasil pemeriksaan laboratorium dinyatakan semua siswa negatif dari infeksi protozoa atau 0%.

Published: July 2024

Measurement of water level is useful as a guide for flood events in an area. As a result of global warming it is predicted that rainfall will increase and the water level will be high, so that the chances of flooding will increase. The method often used in forecasting is the method of Autoregressive Integrated Moving Average (ARIMA). ARIMA is one of the time series forecasting methods that has been studied in depth by Box and Jenkins. ARIMA's basic concepts include,identification of models, parameter estimation, diagnostic checks and forecasting. Forecasting results with the ARIMA method are inaccurate, on data that contains outliers. The weakness of the ARIMA method can be overcome using the ARIMA method with outlier detection. The type of outlier detection in this study is additive outlier (AO). The purpose of this study was to determine the ARIMA forecasting model with an outlier effect on the average water level data of the Mahakam River in the Kutai Kartanegara Region in front of the Tenggarong Museum Building from January 2010 - December 2016. The results showed that the best forecasting model was the river Mahakam Kutai Kartanegara Region is ARIMA ([12], 1,0) with the addition of 4 outlier effects and measure of goodness is AIC with a value of 250,0776.

Published: July 2024

Self-Organizing Maps (SOM) is an efficient cluster analysis in handling high dimensional and large dataset. Particle Swarm Optimization (PSO) is an effective in nonlinear optimization problems and easy to implement. A clustering process occurs if all data can clustered into 1 cluster, however if one or two data did not join then the data have a deviant behavior called outliers or noise.  PSO is used to evolve the weights for SOM to improve the clustering result and to cluster some social aspect in society, for example is poverty. Development strategies are prioritized to regions with largest population lived in poverty. Kutai Kartanegara regency  (Kukar) are recorded as the biggest contributor on population lived in poverty at East Kalimantan in 2017. Development of underdeveloped villages is requires Village Potential data, which focus on visualizing the situation in the regions. This study aims to determine the number of clusters formed and to find the value of Davies Bouldin Index (DBI) from clustering underdeveloped villages in Kukar region using PODES 2018 data. This study uses 9 particle which are the final weight of the SOMs algorithm with different learning rate each particle. Based on the analysis, the optimal number of clusters is 2 clusters with DBI value of 0.7803, where cluster 1 consists of 82 underdeveloped villages and the cluster 2 consist of underdeveloped villages.

This paper analyses the problem of optimal reception of a limited duration signal in a communication channel affected by an additive noise such as non-white non-Gaussian noise. Known solutions are based on the use of an additional “whitening” filter either in front of a filter matched with the signal or in front of a correlator where the reference signal matches the shape of the information signal. Such receiving devices are hard to implement in the case of, for example, intentional interference with slowly changing parameters, which requires filter parameters to be altered. It is proposed to simplify the receiver design by eliminating the whitening filter. The feasibility of two optimal technique options is proven mathematically using the theory of the Lagrange function in the isoperimetric problem of finding the type of function that ensures a minimum noise dispersion and a non-zero value of the signal component. For optimal filtration options, an expression is obtained for the complex transmission coefficient of the optimal (in the indicated sense) filter. For the option when a correlator is used, the optimal type of reference signal has been determined. Expressions have been obtained for the signal-to-noise energy ratio for both options. These expressions coincided with each other, and also agreed with a known relationship for receivers with whitening filters, which proves the possibility of implementing the proposed simpler optimal receiver designs.

The formulation and proof of the theorem on the necessity and sufficiency of three instantaneous readouts of harmonic signals for determining their basic parameters (the amplitude, the frequency and the phase shift) are presented. The developed analog-digital algorithms for determining basic parameters of harmonic signals by the minimum of instantaneous readouts in a time shorter than their period are described on the basis of the proved theorem. The results of mathematical modeling of the developed algorithm of determining the frequency of a harmonic signal by the probabilistic-statistical method are presented. Algorithm errors for determining the frequency of both a pure harmonic signal, and a signal with five harmonics with different accuracy of representation in amplitude of discrete values of signals are investigated.

Published: July 2024

Stunting is a chronic nutritional problem that significantly affects children's growth and development. This community service activity aims to evaluate the impact of education on local Supplementary Feeding (PMT) in combating stunting in Kediri. The method used is education about local PMT as a measure to combat stunting. The study subjects consisted of members of Ibu Persatuan Istri Tentara (Persit) Yonif 521: Dadaha Yodha in Kediri. Data were collected through self-data questionnaires, pretests, and posttests. The results of this activity showed a significant relationship between income, health cadre status, prior knowledge about local PMT and stunting, and the level of knowledge of Ibu Persit members. Moreover, there was an increase in the Ibu Persit member’s knowledge about the role of local PMT in combating stunting and a statistically significant difference in their knowledge levels before and after the education. Education on local PMT has proven effective in enhancing Ibu Persit members' understanding of nutrition and proper dietary practices, contributing to the reduction of stunting prevalence. These findings suggest the need for the widespread implementation of local PMT education programs as a strategy to combat stunting in other areas facing similar problems.

Published: July 2024

World practice shows that constitutional guidelines are gradually being formed in the system of legal coordinates for combating corruption. In order for the process of constitutionalization of the legal parameters of combating corruption to be fully understood and evaluated, it must first be completed, not only in its immediate chronological framework, but also in terms of its long-term consequences, significance for the evolution of constitutionalism, the state and law. Secondly, this process will appear in its true light only within the framework of a large-scale historical perspective. Only it will give an answer to the question of the place and role of this phenomenon in the history of the development of society, state and law. Relying on the historical perspective, which reveals all the most distant consequences of what is happening, allowed the author of the article to make a number of prognostic conclusions.

Published: July 2024

[ANNUAL FLOOD PHENOMENON AND FERTILITY STATUS OF RICE SOIL IN THE COASTAL AREA OF BENGKULU]. The rice fields in Rawa Makmur Village were agricultural land that was affected by annual floods. Soil fertility status is important for increasing the productivity of paddy. The research aimed to get the fertility status of soil affected by annual flood disasters, evaluating and mapping the distribution of soil fertility status at the research location. The methods used in this research include survey and soil testing methods at the Soil Science Laboratory, Faculty of Agriculture, Bengkulu University. Further evaluation of soil fertility status is in accordance with technical instructions from the Soil Research Center, Bogor (1995). This research was conducted in June – August 2023. The soil CEC value from each sampling point was classified as high with values ranging from 28.15 me/100 g - 39.83 me/100 g. The base saturation value in the study was classified as very low to moderate with values ranging from 11.49% - 40.08%. Soil organic C at the research location from each sampling point was classified as moderate to very high with values ranging from 2.42% - 5.97%. The soil phosphorus content at the research locations observed was classified as very low to low with values ranging from 2.69 mg/100 g – 12.11 mg/100 g. The soil potassium content at each sample point at the research location observed was classified as very low with values ranging from 0.14 mg/100 g – 1.43 mg/100 g. The research results show that the flood phenomenon has a significant impact on soil fertility. The soil fertility status at the research location is classified as low. Soil fertility parameters which are limiting factors in the status of soil fertility in Rawa Makmur Village are phosphorus, potassium and pH. So it is necessary to add P and K fertilizer to improve the soil fertility status.
Measuring County-Level Deindustrialization in the United States
Authors: Kurtz Emily
Published: July 2024

Existing measures of county-level deindustrialization in the United States are often single numbers, typically capturing manufacturing job losses over a short time. This misses some nuance because job loss trajectories are not always linear and the starting point is consequential. I implement a time series clustering algorithm to categorize counties based on trends in manufacturing jobs over 53 years for the 2,316 counties with available data. Six distinct clusters represent the major deindustrialization trajectories. Declines have been quite sharp in some clusters, giving those counties less time to transition to a post-industrial economy. These cross-cluster differences are consequential to theories and past findings. For example, I find that TAA claims, a traditional measure of local deindustrialization, meaningfully impact individuals’ views on investment only when they live in non-deindustrialized counties. In deindustrialized counties, views are homogeneous across demographics, except across partisanship, where Republicans are more supportive of investment.
Towards a Theory of Lifespan Personality Trait Development
Authors: Bleidorn Wiebke
Published: July 2024

The lifespan development of personality traits has evolved from a niche topic to a core subject of psychological science. Looking back at 20 years of research, I review the personality development literature against three criteria for strong psychological theories. Overall, the field has come a long way in refining our theoretical understanding of lifespan personality trait development. Major accomplishments include the establishment of evidence-based trait measures, the identification of robust patterns of trait stability and change, and the documentation of both environmental and genetic contributions to lifespan personality development. These insights put the field in the position to make transformative advances towards stronger and more precise theories. However, there are still several open questions. I discuss ideas to overcome existing obstacles to the development of strong lifespan personality theories and close with an overall evaluation of the theoretical status of the field.
Infants’ curiosity impacts cognitive capacity in early childhood
Authors: de Boer Eline R , Poli Francesco , Meyer Marlene , Mars Rogier B. , Hunnius Sabine
Published: July 2024

Recent research has shown that infants are curious and actively seek out situations from which they can learn. When presented with different stimulus sequences on a computer screen, babies tend to allocate their attention to stimuli that offer opportunities for information gain. Interestingly, however, the degree to which attention is guided by information gain varies among individual infants. Our study provides empirical evidence that these early interindividual differences in infants’ curiosity have long-term consequences for their cognitive development. We found that the extent to which infants’ attention was guided by information gain at 8 months predicted their IQ scores at 3½ years of age. These findings are the first to demonstrate the lasting consequences of early existing differences in curiosity-driven exploration for later childhood cognitive development.
A Methodological Approach for Causal Inference under Uncontrolled (and Possibly Latent) Pre-exposure to Treatment
Authors: Ferrari Diogo
Published: July 2024

Experiments have become one of the main tools for causal inference in political science, but scholars have raised concerns regarding the uncontrolled real-world pre-exposure of subjects to the information manipulated during the experiment. This pre-exposure can mislead conclusions about the treatment effects, and the problem is exacerbated because direct measurement of pre-exposure is not feasible in many studies due to the risk of confounding the experiment. This paper presents a method to estimate causal effects when pre-exposure is uncontrolled and directly unobservable. It formalizes the problem using the potential outcomes framework; decomposes the average treatment effect (ATE) into pre-exposure and exposure components; derives the bias that emerges when pre-exposure is ignored; establishes sufficient identification conditions; and introduces a bias-corrected estimator for the relevant causal parameters. The method is applied to analyze the impact of party cues on voters' policy attitudes.
Boundless but Bundled: Modelling Quasi-infinite Dimensions in Ideological Space
Authors: Warncke Philip , Azevedo Flavio
Published: July 2024

Ideological summary scales, derived from policy position items, are prevalent in political psychologyand behavioral research. However, past scholarly practice shows little to no consensus as to howmany such scales (i.e., ideological dimensions) researchers should consider in order to adequatelycapture the main political dividing lines among mass publics. Our comprehensive literature reviewsuggests — and extensive statistical simulations using ANES and CCES data confirm — that theoptimal number of latent ideological dimensions grows indefinitely as researchers include additionalissue position items in their models. Instead of increasing measurement precision, additional issueposition questions thus increase uncertainty about what underlying construct they are supposed tomeasure in the first place. At the same time, nearly all latent ideological factors detectable withinpolicy position data are sizably and positively correlated with one another, suggesting that ideologicalsub-dimensions ultimately stem from a more abstract, unifying parent dimension. We propose aBayesian hierarchical latent variable modeling framework which seeks to reconcile the boundless, yetcorrelated dimensional nature of mass ideology. The proposed model estimates ideology as a higherlevelexpression of correlated, lower-level building blocks, allowing researchers to simultaneouslyevaluate whether external predictors, such as income or gender are consistently related to specificideological sub-dimensions (e.g., economic or socio-cultural ideology) or, instead, a generalized,uni-dimensional representation thereof. Our results underscore the potential of this approach, offeringinsights into the unique characteristics of different ideological sub-factors and their overarching parentdimension.
Evaluating the Flood Vulnerability of Urban Areas in Polk County, Iowa using Social-Ecological-Technological Framework
Authors: Cikmaz Atiye , Mount Jerry , Demir Ibrahim
Published: July 2024

The escalating prominence of floods globally, with their catastrophic potential to inflict substantial losses in terms of both human lives and economic resources, underscores their significance. Particularly susceptible to flooding between May and July, the US Midwest faces heightened risks during this critical period, characterized by the highest average precipitation rates of the year. Flood vulnerability assessments furnish organizations with crucial insights into expected extreme events and strive to mitigate potential harm from these risks. The Social-Ecological-Technological (SETS) framework, a comprehensive flood vulnerability assessment method, highlights the significance of aligning natural, technological, and demographic systems to comprehend and effectively address the complexity of natural hazards, facilitating the achievement of optimal results. In this study, the relationship between the 500-year flood event and the SETS vulnerability indices formed by 18 selected parameters was examined for Polk County, Iowa. Moreover, linear regression and spatial autocorrelation analyses were conducted on vulnerability indices. The results indicated that the S-E-T vulnerability map, which is the combined effects of all social, ecological, and technological exposure, sensitivity, and adaptive capacity parameters considered, the areas most impacted to damage are identified as the highly populated downtown Des Moines, where urban development is concentrated along a highway (I-235) and large industrial buildings. When looking at all the vulnerability maps produced, the number of census block groups in the very high vulnerability class is low. However, in Polk County, it has been presented that there is strong spatial autocorrelation indicating that vulnerability index values are highly clustered. These findings will support sustainable approaches and stronger contextual solutions for city managers and practitioners that decrease the risks of flooding in Polk County communities.
Foundational Mechanics and Baseline Simulation of the Diaphragm
Authors: Ula Shafin
Published: July 2024

The absence of experimentation and analysis regarding the mechanics of the Diaphragm in the active state or the tetanized state of the Diaphragm muscle signals for a need of research to account and simulate the mechanics of this particular state. To simulate a basic structure of the diaphragm in a certain period, mathematical equations outlining the shape of the diaphragm generated by Prof. Yi-Chao Chen from the University of Houston from previous experimentations was utilized in the simulation code. Consequently, a video was created that provided a base simulation of the mechanics and motion of the diaphragm during its expansion and contraction phases. This study and any associated code serves as a foundation for the advancement of the collective research of our lab group, with the lead investigator being Prof. Yi-Chao Chen and as a gateway for future research on the mechanics and mathematics associated with the Diaphragm motion in the active state.

Psychological science has long maintained a preference for quantitative methods over qualitative methods. The allegiance to one methodological family and the rejection of another means that, at least in part, our methods are constraining the universe of research questions we are willing to ask. This article provides an overview of mixed methods research, which involves the use and integration of both qualitative and quantitative methods, and why psychology should do more of it. The paper consists of three general sections: 1) a brief discussion of philosophical issues underlying the application of mixed methods research in psychology, 2) a deeper examination of what constitutes “quantitative” and “qualitative” research, and 3) a description of four major mixed methods research designs that hold promise for psychology research. The paper provides researchers with broad conceptual foundations and concrete tools for how research questions in psychology can be mapped to different mixed methods designs, helping correct for researchers’ lack of exposure and/or negative preconceptions that have inhibited uptake in the field.
Assessing conspiracist ideation reliably, validly, and efficiently: A psychometric comparison of five short-form measures
Authors: Kay Cameron Stuart , Slovic Paul
Published: July 2024

Choosing a short-form measure of conspiracist ideation is fraught. Despite there being numerous scales to choose from, little work has been done to compare their psychometric properties. To address this shortcoming, we compared the internal consistency, two-week test-retest reliability, criterion validity, and construct validity of five short-form conspiracist ideation measures: the Generic Conspiracist Beliefs Scale – 5 (GCB-5), Conspiracy Mentality Questionnaire (CMQ), General Measure of Conspiracism (GMC), American Conspiracy Thinking Scale (ACTS), and One-Item Conspiracy Measure (1CM). The results of our investigation indicated that all five of the scales are reliable and valid measures of conspiracist ideation. That said, the GCB-5 tended to perform the best while the 1CM tended to perform the worst. We conclude our investigation by discussing trade-offs among the five scales, as well as providing recommendations for future research.

Background and aims: Acute kidney injury (AKI) is associated with increased mortality, morbidity, and hospital stay. AKI is seen in 20-60% of patients admitted to the intensive care unit (ICU), and mortality is as high as 50% if not managed timely. Burden of AKI is more in developing countries as compared to the developed ones. There is a paucity of published literature regarding incidence and outcome of AKI in critically ill patients from lower-middle income countries like Nepal. This study aimed to determine the incidence and outcome of AKI in patients admitted to a level III ICU in Nepal.
Methods: This observational study was conducted in the ICU of Hospital for Advanced Medicine and Surgery (HAMS) Hospital, Kathmandu, Nepal. Data over a period of one year was curated from ICU registry. Eligible patients were screened and the incidence of AKI in ICU admitted patients along with their outcomes (length of ICU stay, need of RRT and ICU mortality) were observed.
Results: Among 881 patients admitted to the ICU, 660 patients were enrolled for analysis. Of them, 14.2% of patients developed AKI during ICU stay, out of which 5.3% received RRT and 19.1% died. The median (IQR) length of ICU stay for those who developed AKI was 4 (3-7) days. The 34.0% patients who developed AKI had sepsis.
Conclusion: Patients admitted to ICU in this study have high incidence of AKI. In patients who developed AKI, sepsis was the leading cause of ICU admission.

People are now concerned more about environmental issues and desire to buy eco-friendly products. As awareness of green products has expanded, a growing focus has been on green product consumption. Therefore, this study aims to determine the factors influencing consumer buying intention towards green products in Bangladesh. In this regard, we developed a research model with the concepts of environmental awareness, green product awareness, green product price, green promotion, and health concerns. We collected empirical data through an online survey of 313 respondents interested in green product consumption. The suggested relationships in the proposed model were examined using the structural equation model. The data was analyzed using SPSS 25.00 and Smart PLS 3.0. The results of this study show that environmental awareness, green product awareness, and health concerns significantly influence the attitude towards green products, which, in turn, influences green product buying intention. The findings also indicate that health concern is the most significant factor in predicting users' attitudes towards green products. The findings suggest that this comprehensive model can improve green product purchase intention, boost sales, and influence this area favourably.
