Investigating Respect in Learning as Character Education: A Review of al-Zarnūjī’s Ta‘līm al-Muta‘allim
Authors: Huda Miftachul , Selamat Abu Zarrin , Salem Sultan
Published: May 2024

Respect has been shown to provide psychological, social, and academic advantages; nevertheless, most academics have not given it enough credit in terms of encouraging students’ character development. Al-Zarnūjī’s idea, a classical Muslim scholar, as a point of reference for his esteemed work on the concept of Ta‘līm al-Muta‘allim has been one of the references in learning and teaching guidelines among pesantren (Islamic boarding schools) in Indonesia. This article aims to critically explore respect as a moral concept and explain how respect can contribute to current discussions in developing character education from the perspective of al-Zarnūjī’s Ta‘līm al-Muta‘allim. A critical analysis of books and journals that were cited was done concerning the contributions made in the field of character education. The study’s findings have led to three major disputes. The first is deference to knowledge as a source of illumination. Secondly, it is deference to the instructor as the foremost exemplar and facilitator of information exchange; and thirdly, it is honoring the colleague as a fellow participant in the educational journey. Respect in all of its dimensions should thus guide the process of teaching and learning.

Published: May 2024

Gestational Diabetes Mellitus (GDM) is diabetes that occurs during pregnancy. GDM is characterized by hyperglycemia. Hyperglycemia causes an inflammatory response characterized by the excretion of pro-inflammatory cytokines, one of which is IL-6. Centella asiatica and Rosmarinus officinalis are known as anti-diabetic and anti-inflammatory. This study aims to study the effect of the combination of nanoemulsion Centella asiatica and Rosmarinus officinalis on the expression of Interleukin-6 in Zebrafish larvae induced by 3% glucose. Hyperglycemia is known from increased levels of Phosphoenolpyruvate carboxykinase in Zebrafish larvae. Phosphoenolpyruvate carboxykinase and Interleukin-6 expression were measured by conventional PCR method. The combination of Rosmarinus officinalis nanoemulsion and Centella asiatica was given with three different doses, namely at a concentration of 2.5, 5 and 10 µg/mL. The statistical analysis used was One Way ANOVA to measure Interleukin-6 expression levels. The results of this study prove that the combination of Rosmarinus officinalis and Centella asiatica nanoemulsions reduces the expression of Interleukin-6. The dose closest to the negative control was at a concentration of 5 μg/mL, although the final result was statistically significant (p<0.05). In conclusion, combining nanoemulsion Centella asiatica and Rosmarinus officinalis with the right dose reduced levels of Interleukin 6 in zebrafish larvae induced by high glucose.
FROM DOMESTIC TO PUBLIC: THE CONSTRUCTION OF WOMEN'S EMPOWERMENT DISCOURSE IN SAUDI ARABIA’S VISION 2030
Authors: Ainurrofiq Faiq , Khasanah Nurul
Published: May 2024

The involvement of women in the public sphere in Saudi Arabia has increased after Crown Prince Muhammad bin Salman officially declared the vision of Saudi Arabia 2030. In contrast to Saudi Arabia's Wahhabi clerics who tend to domesticate the role of women, the government in its vision actually encourages women to be involved in the public sphere. This paper seeks to describe the discourse on women's empowerment and reveal the ideology that underlies it and to explain the implications of the construction of this discourse on changes in public policy in Saudi Arabia. The author use critical discourse analysis as an analytical tool. The author concludes, First, the discourse on women's empowerment in the Saudi 2030 vision document is manifested in giving equal roles to women and men to be involved in social and economic activities. Women in Saudi's 2030 vision are positioned as national assets that are open, competitive, hardworking, and able to drive the economy. Second, the discourse that encourages women to be involved in public activities is inseparable from the ideology of the current Saudi Arabian government which tends to lead to socio-economic liberalization. In this context, women's empowerment is used for the benefit of economic growth and the transformation of new, more open religious social conditions (infitah). Third, the discourse on women's empowerment in the Saudi 2030 vision influences changes in public policy in Saudi Arabia. The old policies from the rulings of the ulama were replaced with new policies that gave women more freedom to participate in the public sphere.

ABDURRAUF SINGKEL’S INSAN KAMIL CONCEPT TO ANSWER THE PROBLEM OF SEXUAL CONSENT, CHILDFREE, NATURE AND NURTURE IN URBAN SOCIETY
Authors: Ihsan Nur Hadi , Sa'ari Che Zarrina Binti , Sansayto Tistigar , Indallah Sayyid Muhammad
Published: May 2024

This article aims to analyze Abdurrauf Singkel's concept of Insan Kamil to address the problems of sexual consent, childfree, and nature and nurture which frequently arise in urban society. These issues are a common phenomenon in contemporary urban society due to their materialistic lifestyle and the pursuit of worldly goals by denying their true nature (fitrah). Sufism's concept of "Insan Kamil" depicts the ideal human being from every perspective—that is, the ideal human being as he is by nature. This concept of the perfect human will serve as an antidote to the three problems above, each of which is a deviation from the essence of human nature. This paper is a qualitative library research that analyzes data using an analytical descriptive method. This study concludes that, first and foremost all of these issues stem from the same root cause which is a denial of human nature. As a concept of the perfect human, Insan Kamil is a manifestation of achieving the pinnacle of humanity based on true human nature. Insan Kamil is also a condition of servitude to the highest degree or ihsan. Therefore, this concept is relevant to overcoming the root problems of sexual consent, childfree, and nature and nurture which stem from the denial of one's nature. By becoming Insan Kamil, someone can place himself according to his nature in the right and proper place.

Published: May 2024

Background: This study aimed to assess the impact of the COVID-19 pandemic on cases of Dead on Arrival (DOA).
Methodology: A retrospective chart review was conducted on all DOA files and electronic records from January 2019 to December 2020 in a tertiary care hospital in Karachi, Pakistan. The study compared the number of DOA cases before and during the COVID-19 pandemic and estimated the proportion of DOA cases that tested positive for COVID-19. Excess mortality for 2020 was calculated using linear regression with data from the previous five years.
Results: Out of 950 DOA cases, 442 were recorded before the pandemic and 508 during it. The mean age of the deceased was 57.51 (±24.12). Among the 508 deaths during the pandemic, only 38 cases underwent COVID-19 testing, with 5 (13.1%) testing positive (p=0.864). The expected number of DOA cases for 2020 was 454, whereas the reported number was 508, indicating an excess of 54 cases.
Conclusion: The study suggests an increase in DOA cases in 2020, possibly attributable to the ongoing COVID-19 pandemic.

Published: May 2024

Background: Healthcare professionals (HCPs) are at increased risk of contracting hepatitis B due to frequent exposure to patients with the disease. Post-exposure prophylaxis (PEP) can effectively manage this risk. This study aimed to assess the level of awareness of hepatitis B PEP among healthcare workers in the Quetta district.
Methodology: Conducted from November 1, 2022, to November 30, 2022, this cross-sectional study targeted healthcare professionals in Quetta, Balochistan, Pakistan. Data were collected from three main public tertiary care institutions and various private hospitals using simple random sampling. A structured questionnaire covering demographic information, immunization status, and hepatitis B PEP was administered. Data analysis was performed using SPSS version 19, summarizing data with frequencies and percentages. Odds ratio analysis was conducted to identify associations between awareness of hepatitis B PEP and other variables.
Results: Of the 263 participants, 181 (68.8%) were female, and 167 (63.5%) were aged 31-40 years. Most participants (88.5%) were doctors, followed by nurses and pharmacists. While 87.1% had heard of hepatitis B PEP, only 11.8% received formal training on it. Awareness of PEP components was lacking, despite familiarity with its existence. Factors associated with awareness included previous PEP knowledge, hepatitis B screening, and perceived job-related risk.
Conclusion: Although many healthcare providers were aware of hepatitis B PEP, knowledge regarding its components was insufficient. Training and education initiatives are crucial to improving awareness and understanding among healthcare professionals.
The process of literacy integration in agriculture classrooms : a grounded theory /
Authors:   , Hasselquist Laura
Published: May 2024

The purpose of this grounded theory study was to conceptualize how agriculture teachers' beliefs and literacy experiences translate into classroom practices. The emergent theme focused on teacher belief drivers which started the process of literacy integration. Once they felt driven to include literacy, the participants worked through a variety of considerations. At times, the participants felt it was necessary to seek out additional support structures to enable the integration process. Incorporating literacy was not free of challenge or struggles, but the participants had sustaining experiences to help them stay motivated during the integration process. A substantive level theory was developed to illustrate the relationships between these themes and the literacy integration process. Future research should explore if typical agriculture teachers follow a similar process and if additional supports help increase integration.
Plasma treatment effects on resin-based tooth restoration improvements
Authors:   , Tan Jingwen
Published: May 2024

[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] The dental restoration is the recovery of the function, integrity and morphology of missing tooth structure using dental restorative materials. Recent years, safety and aesthetic concerns have increasingly driven dental restorations from using metallic to resin composite materials. However, resin composite restorations displayed a prohibitively failure rate, especially after longevity tests. High failure rates necessitate frequent replacements which lead to increased loss of sound tooth structure and more complicated subsequent restorations. To elongate the lifetime of composite restorations, novel methods are highly required. The non-thermal plasma technique has been applied in the dental restoration. Plasma treatment exhibits outstanding effects on dental substrates modifications. However, the resin-tooth (enamel, dentin) bonding interface performance needs to be evaluated. This study focuses on the evaluation of plasma treatment on dental bonding strength improving. Different dental substrates, including enamel, dentin and dental ceramic were employed in this study. The plasma treatment exhibited enhancement effects on resin-enamel, resin-dentin, and resin-ceramic bonding under a range of plasma operating conditions. Micro-tensile and micro-shear bonding strength tests were conducted to evaluate the plasma treatment effects on the bonding strength. SEM measurement was also applied to exam the bonding cross-section and fracture surface morphology. To further explore the mechanism of bonding enhancement, the dental substrates surface chemistries information was scanned by FTIR and ATR-FTIR facilities. From our results, plasma treatment consistently increased the resin-enamel, resin-dentin, and resin-ceramic bonding strengths, while the underlying mechanisms of bonding improvements were complex. First, plasma treatment increased the dental substrates wettability and improved the adhesive resin infiltrations. Second, plasma treatment improved the monomer (e.g. HEMA, GDMP etc.) grafting on tooth substrates and enhanced the monomer bonding to dental substrate at bonding interface. In additional, the plasma treatment could induce adhesive resin polymerization and obtained more durable adhesive layers. Regarding to ceramic bonding, plasma treatment improved the distribution of silane coupling agents coating on zirconia ceramic surface, which lead to tighter resin-ceramic bonds. In conclusion, non-thermal atmospheric plasma treatment is a very effective method in both direct and indirect restoration performance. The experimental results settled the fundamentals of the plasma techniques application in dentistry.
P-V-T properties of methyl chloride at high temperatures and pressures
Authors:   , Suh Kyung Won.
Published: May 2024

"The equation of state of a gas describes the relation between the three variables pressure, volume, and temperature. Many equations have been proposed which accurately describe the p-v-T relations of real gases (3,4,5,8,18,20, 26,31,32,39,51,58,70,74,90). Some of these are purely empirical while others are derived from the intermolecular properties. A knowledge of the equation of state is necessary for obtaining equilibrium properties of pure substances. The volumetric behavior of non-polar gases may be described by the application of the principle of corresponding states, which has been successful in predicting compressibility factors and second virial coefficients for both pure gases and binary gas mixtures (19, 24, 25, 34, 35, 49, 54, 59, 63, 66, 67, 71). Polar gases deviate considerably from the principle of corresponding states, and require different treatment. Two methods have been used in predicting the second virial coefficient of polar gases. The first method uses statistical mechanics and an intermolecular potential function based on a physical model. The second method is based on a hypothesis, first proposed by Eucken (21), that polar gases undergo partial association due to dipole interaction or to hydrogen bonding, and that this is responsible for their deviation from the principle of corresponding states. This method of interpretation was originally applied by Alexander and Lambert to their results on acetaldehyde (1), and later by others to interpret the second virial coefficients (10,23,30,33,46,47). In this investigation the first approach was used to analyze the experimental second virial coefficient data. In this investigation, the Kihara core model was used to represent the geometry of a polar molecule. A permanent point dipole was placed in the core and used to represent the polar contribution to the molecular pair force field. Pople's perturbation method (68) was used to obtain an expression for the second virial coefficient of a polar gas. Numerical methods were then used to evaluate the potential parameters for nine polar gases. Derived thermodynamic properties of methyl chloride were also calculated from the calculated B(T) values for the modified Kihara potential and compared with those calculated from the p-v-T data."--Introduction.
Scale and utilization economics in feeding cattle under three feeding systems : a feasibility study
Authors:   , Florea Bruce J.
Published: May 2024

"Since the end of World War II the cattle feeding industry in the United States has been characterized by three major, and to a certain degree, related developments: 1. A marked expansion in numbers. In the two decades from 1945 to 1965 the number of cattle on feed January 1 in the 26 principal cattle feeding states increased 115 percent. A shift in location from the west north-central states to the southern plains and the western United States. From 1946 to 1965 the west north-central states' share of the number of cattle fed dropped from 60 percent to 47 percent. While at the same time the proportion accounted for by the southern plains and the western states advanced from 18 percent to 33 percent. 3. A shift in the structure in the industry from the traditional corn belt farmer-feeder who feeds cattle primarily as a complementary enterprise and who views cattle as a means of utilising his surplus labor and some farm-produced feedstuffs for which a market is either non-existent or negligible-a shift from this type of operation to the large, strictly commercial feedyard where all inputs are purchased, and where feeding cattle is the major, if not the sole enterprise. Since World War II the cattle feeding industry has evolved into a clear-cut dichotomy made up of these two segments. To be sure, there are graduations. But in the main, one has little difficulty in categorizing a particular operation into one or the other of these two groups."--Introduction.
Application of the systems approach : an information and decision model for the hog enterprise
Authors:   , Devisch Noel R.
Published: May 2024

"Subject of Dissertation: The purpose of this dissertation is to develop a dynamic model for hog enterprises in which a complete information system is incorporated. It will provide the farmer with several plans of action, each yielding expected values for the different criteria that might relate to his goals. A plan will be selected for detailed examination as to its financial feasibility, the risk and uncertainty involved and the operational procedure for implementing the plan and checking the implementation. Before building and using the actual model, a review of the relevant literature will be made in section one. In the first chapter, some commonly available methods in farm planning are critically reviewed and their usefulness for planning hog management decisions is discussed. Appendix A defines some elements of the specialized jargon used in systems approach and simulation and describes some important aspects of the method of systems approach. Chapter Two reviews the use by previous researchers of simulation models for planning hog management. Section Two of this study is devoted to the development of a complete information and decision model for planning Missouri hog farms. The specific objectives of the study and the construction of the model are described in Chapter Three. The data that goes into the model, including the prediction of the most relevant prices are reported in Chapter Four. Chapter Five provides some elements of economic theory in relation to the decision making on hog farms concerning output and expansion. Simulation of the decision making is carried out in Section Three. Response surfaces with respect to different criteria are estimated through a systematic simulation procedure and a statistical analysis of the results is made. This is reported in Chapter Six. The practical use of the model for planning and control of the hog operation is described in Chapter Seven. A final chapter summarizes the approach, draws conclusions and makes suggestions for further research in this domain."--Page 4.
A comparative study of the Lupinus parviflorus complex
Authors:   , Harmon William Edward
Published: May 2024

The taxonomic history of the genus Lupinus began with Linnaeus who adopted Tournefort's term. Even a cursory look at the subsequent history of the genus brings to the forefront the diversity of opinions that have been expressed among those taxonomists who have investigated the various taxa of lupines. It should be noted, however, that these early taxonomists were forced to attempt an understanding of the genus by making observations on the morphology alone. However, even in more recent years a divergence of opinion has been expressed in spite of the rather widespread acceptance of the "biological species" concept and broader understanding of the processes of speciation. It was an awareness of the confusion in the genus that suggested an integrated approach, making use of as many of the modern tools of taxonomic research as possible, be taken to investigate a small group of lupines. The small flowered, perennial lupines of the mountainous areas surrounding the Great Basin of the western United States were delimited as a suitable group of taxa to work on. Investigations proceeded on these taxa in three areas. A preliminary field survey of the principal pollinators and their behavioral characteristics was made in an attempt to find the correlation, if any, between flower size and the size of the pollinators. Ultimately a quantification of the gene flow, actual and/or potential, will be necessary before the origin of variability within the genus can be understood. In a second are a of investigation, a survey of the alkaloid spectra of the Lupinus parviflorus complex and allied taxa was made. The set of non-morphological characters available in the alkaloids of each taxon represented another group of characters from which relationships between taxa could be evaluated. The alkaloids present in each of the taxa were examined with the aid of thin layer chromatographic techniques. Finally, in spite of the fact that alkaloids provide an additional set of descriptors for analysis of these small flowered lupine taxa, morphology remains the most practical way of evaluating genetic relationships between such taxa. Modern techniques of computer aided numerical analysis were employed to evaluate the characters traditionally used to describe lupines. Once the characters were evaluated, those that are most efficient at describing the taxa can be used to construct a model based on the overall phenetic similarity of the taxa. Such phenetic models serve as a useful context for relating other types of data such as those attained from field studies, distributional patterns, chromosome counts, chemotaxonomic studies, etc. The integrated results of the pollinator study, the chemotaxonomic analysis of the alkaloids and the taximetric analysis of themorphology were used to interpret the relationships of the Lupinus parviflorus complex and allied taxa. The relationships between these taxa a represented in the taxonomic treatment, along with descriptions, distribution maps and illustrations of representative specimens of each taxon.
Uncertainty and the microfoundations of supply response : some theoretical considerations and an empirical application in the U.S. corn market
Authors:   , Holt Matthew T.
Published: May 2024

This study has examined how a micro-level decision model which incorporates uncertainty can be reconciled with observed market behavior. Conditions under which a firm-market correspondence exists in a deterministic environment are well defined. However, similar relationships have not been developed when agents are risk averse. A detailed theoretical framework is presented which establishes the conceptual linkages between the firm and market. A unique feature of the theory is that agents have rational expectations about all relevant moments of the equilibrium price distribution. The theoretical model is extended to admit the possibility of government intervention. The stylized voluntary government program includes planting restrictions and price supports. The rational expectations hypothesis is appropriately amended to allow for the truncation effect of the price support on the moments of the price distribution. Although many questions pertaining to industry behavior and program design can be addressed with the theory, it is ultimately necessary to test the theoretical implications with an empirical model. The U.S. corn market is used in an empirical application. Importantly, the supply equations are derived from an expected utility maximization framework. In addition, the correspondence between the firm and market is maintained and the rational expectations hypothesis, including truncation effects, is fully incorporated. Supply equations and input demands are also estimated for both participants and nonparticipants in the government program. The empirical model provides a rich framework for conducting policy analysis. For instance, it is possible to experimentally determine certainty equivalent income tradeoffs between acreage restrictions and price supports. The empirical results indicate that relatively large increases in the set-aside requirement can be compensated for by small increases in the support price. This result follows directly from the truncation effect of price supports on producer expectations and illustrates the importance of risk in stabilization analysis.

Authors:   , Dziekanowski Chester Thomas
Published: May 2024

"The genus Lupinus officially dates back to Linnaeus (1753) and Tourenfourt is credited with originating the name in prelinnean work; however, a species had been illustrated in an Old World herbal back to the time of the early Greeks. The ancients used lupines for various purposes. Linnaeus recognized six species of Lupinus. Then with the concomitant increase in exploration numerous newly discovered lupines were named. The first monograph of the lupines was that of Agardh (1835). They were next revised by Watson (1873). The next extensive work was that of C. P. Smith from 1917 to 1953 in which he published the names of many new taxa and recombinations. Periodically Smith contributed to various floras, but all of Smith's work was on a morphological basis only. By this time the various taxa of Lupinus were in a very confused state, and the present study is an effort to clarify and re-evaluate one particularly confusing group of annual lupines of southwestern United States and northwestern Mexico. In addition to extensive herbarium material which has accumulated since Smith worked on the "Sparsiflori" in 1920, the application of breeding studies is employed to evaluate the taxa on a biological basis. Breeding studies can indicate relationships which may not be recognized on a strictly morphological basis. Hybridization in plants has been recognized since the time of Linneaus (Porter 1967). It has been, however, only within recent decades that hybridization has been used to resolve previously chaotic taxonomic situations. Along with hybridization studies, pollen viability, as indicated by staining with cotton blue in lactophenol, may indicate putative hybrids or anomalies in pollen production. A reduction in percentage of stainable pollen is considered indicative of genetic conflicts during meiosis. For greater accuracy in the measurements of the parts of the flowers, the flowers are boiled, stained and mounted for permanent reference. The genus Lupinus has had a long history which is reviewed from the time when ancient civilizations used lupines up to and through the expansion and exploration of the New World during which many new taxa were found. The geography and geology of the area in which the taxa are indigenous is reviewed as these affect the habitat and the pathways of plant migration. A description of the vegetation zones and communities inhabited by the "SparsifIori" and their allies is discussed. With consideration of hybridization and pollen studies and floral and vegetative measurements, as well as accurate distributional data, several new taxonomic and nomenclatural changes are made. The former Sparsiflorus- Concinnus complex of Smith forms three complexes, as well as including several allies of uncertain affinities which were intersterile in the breeding studies. Only the Sparsiflorus complex and allied taxa will be presented in the present work."--Introduction.

Characterization of pigment-protein complexes in the cyanobacterium Anacystis Nidulans R2

Intrinsic membrane proteins associated with photosynthetic electron transfer have highly-conserved analogs in both cyanobacteria and chloroplasts. However, the protein complexes required for light-harvesting are quite different. Cyanobacteria contain extrinsic phycobilisomes, whereas chloroplasts have integral membrane light-harvesting Chl-protein complexes. We show that cyanobacteria are capable of synthesizing an intrinsic light-harvesting structure (termed CPVI-4) similar in many respects to that found in chloroplasts. In normally grown A. nidulans R2, the main light-harvesting structure is the extrinsic phyco- bilisome, whereas under iron stress, phycobilisome quantities decrease and the cells accumulate CPVI-4. CPVI-4 was biochemically purified and characterized with respect to its spectral and biochemical properties. Antisera were raised against an apoprotein of CPVI-4 (34 kD) as well as several other membrane components regulated by iron. The antibodies were used to follow the kinetics of the disappearance of each of these components following addition of iron to iron-depleted cultures. Phycobilisome linker and anchor polypeptides were found to be specifically glycosylated, and purified phyco- bilisomes were found to contain significant quantities of carbohydrates (particularly glucose). The glycosylated sub-units contained differential quantities of glucose and N acetylgalactosamine, and these sugars were present on regions of the linker proteins previously shown to be important for PBsome assembly. These findings have broad implications regarding both the function and assembly of phycobilisomes as well as the response of A. nidulans R2 to a variety of different stress conditions.
