Repeatability underpins a basic assumption in science which students must learn in order to evaluate others’ research findings as well as to communicate the results of their own research. By attempting to repeat the methods of published studies, students learn the importance of clear written communication, while at the same time developing research skills. I describe three examples of published field studies that can be used as the basis for course exercises on the repeatability of methodology, as well as field sampling techniques, all grounded in the overall topic of environmental change. Two of the exercises returned students to the exact location of the past research that they had previously read from the primary literature, making it possible to clarify the difference between reproducibility and repeatability in field-based research. When student-collected data differed from published results, students explored, through both post-project discussions and written work, factors that could explain this variation, including methodology, ecological succession, and climate change. Assessments and student comments on course evaluations showed that these exercises have a positive impact on students’ communication skills and engagement with the scientific process.

In this review article the usage of waste sewage sludge and the biomass ash for improving the engineering and non-engineering properties’ of both concrete and soil are discussed in detail. Numerous past research works were studied in detail so as to predict the behavior of biomass ash and waste sewage sludge when used for the stabilization process of soil and concrete. Past studies related to the usage of stabilized sewage sludge and biomass ash were studied in a detailed manner and depending upon the past studies several conclusions has been drawn which are discussed further. Several studies related to the usage of the waste sewage sludge for improving soil physical, chemical and biological properties showed that the usage of waste sewage sludge improve the physical properties, chemical properties, macro-nutriential properties and micro-nutriential properties up to a great extent. Depending upon the results of the past studies it can be concluded that the usage of sewage sludge has positive impact over all the properties of soil and this waste should be utilized in improving the properties of soil rather than dumping. Numerous studies related to the usage of the biomass ash showed that biomass ash has positive impact over both soil as well as concrete. Studies related to the usage of the biomass ash in soil showed that there was a positive response of the stabilized soil after its stabilization with the biomass ash. Studies related to the usage of the biomass ash in concrete showed that the biomass ash can be used up to 10 percent replacement of the ordinary Portland cement so as to attain maximum strength results from it.

<p class="06IsiAbstrak">The outbreak of the Covid-19 pandemic has penetrated all people globally, including the Indonesian people who feel that the teaching and learning culture must follow health protocols. Still, the learning process must continue even though it is limited. This study aims to determine curriculum adaptation during the Covid-19 pandemic, teacher strategies, and its impact on MI Salafiyah Tajungsari and SDN Sitiluhur 02. This type of research used qualitative field studies with data sources for school principals, curriculum development teams, and teachers. Methods of data collection using observation, interviews, and documentation. Data analysis includes data reduction, data presentation, concluding, and verification. The technique of testing the validity of the data used triangulation of sources and methods. The research findings showed that MI Salafiyah Tajungsari uses an emergency curriculum with essential materials, while SDN Sitiluhur 02 uses a curriculum that simplifies critical competencies. The learning strategies used by teachers include online and offline. The difference lies offline. Offline at MI Salafiyah Tajungsari held limited face-to-face meetings, while offline at SDN Sitiluhur 02, students carried out the tasks assigned by the teacher and submitted their work to school. The impact of the adaptation curriculum has made the competency target of the school not maximally achieved.</p>

This article is targeting at examining the difference between the impact of culture and technology on the knowledge management (KM) practices. It holds two points: first is why the existing research relies heavily on cultural approach to KM and the second one is why technology view of KM is neglected in the past research. Most scholars have rated organizational culture highly over tech-nology (IT). This premise has been largely made in context of knowledge sharing, with technology enabling this transfer. As KM matured from sharing to creating knowledge, scholarly views, however, have remained unchanged. This stubborn viewpoint—culture precedes technology—weighs behaviours and attitudes, collectively called culture, compared to the technology thus, limiting its scope. This research attempts to find out if KM practitioners agree to this notion. Whose contribution they value more—culture or technology? Our research assessed the role of culture and technology, individually, for their impact/contribution to overall KM practice. We found practitioners testifying against the above hypothesis, giving credit largely to technology for KM success in their organizations, over culture. Our research further outlines the reasons why culture has taken the backseat and what contribution technology has been making to successful KM practice.

Research Findings

Conceptual knowledge is one of the mathematical knowledge areas which should be mastered by mathematics teachers besides factual, procedural, and metacognitive knowledge. Teachers are prone to cast conceptual knowledge aside and prioritise procedural knowledge without understanding the concepts which influence the options of mathematical strategies and models in the context of problem solving. A literature review was conducted to discuss past research findings in identifying secondary school teachers' conceptual knowledge in the algebra topic. 68 past research articles were referred to and chosen based on the research purpose which was to investigate mathematics teachers' conceptual knowledge level and its implementation in several mathematical topics quantitatively and qualitatively in local and international contexts.  There have been a lot of researches conducted on teachers' conceptual knowledge in several mathematical topics, however there is still a lack of research in investigating teachers' conceptual knowledge on the algebra topic. Most of the past research findings showed that the teachers' conceptual knowledge level was at a low level in several mathematical  topics therefore a similar research is also needed in the algebra topic. This study can be extended to a more improved research in spite of the research sample, design or research methodology, instruments, and other factors.

This study aims to explore the factors determining consumer loyalty to real estate agents. Based on the past literature regarding the factors of loyalty, the study considers physical attractiveness and intellectual competence combined with a traditional loyalty model in proposing its conceptual framework. It then estimates the relevant parameters using a linear structural equation model (SEM). The subjects of the study consist of consumers in Kaohsiung City, Taiwan, aged at least 20 years old who have experience in engaging the services of real estate companies during housing transactions. A total of 300 questionnaires were distributed, with 268 valid ones being returned, for a valid return rate of 89.33%. According to the empirical results, physical attractiveness indirectly influences satisfaction through trust and intellectual competence, with satisfaction in turn affecting customer loyalty. The effect of physical attractiveness on satisfaction through trust is more significant than its effect on satisfaction through intellectual competence. These findings show that the relationship among physical attractiveness, intellectual competence, and trust plays an important role in determining satisfaction and loyalty. Past studies related to loyalty introduced various factors of loyalty; however, they rarely explored the effects of physical attractiveness and intellectual competence on loyalty. That is the difference between this study and past research.

The Past

In recent years, research on the production of active peptides obtained from milk and their potential functionality has grown, to a great extent. Bioactive peptides have been defined as specific protein fragments that have a positive impact on body functions or conditions, and they may ultimately have an influence on health. Individual proteins of casein or milk-derived products such as cheese and yogurt have been used as a protein source to study the isolation and activity of peptides with several applications. Currently, the milk whey waste obtained in the production of cheese also represents a protein source from which active peptides could be isolated with potential industrial applications. The active properties of milk peptides and the results found with regard to their physiological effects have led to the classification of peptides as belonging to the group of ingredients of protein nature, appropriate for use in functional foods or pharmaceutical formulations. In this study, the main peptides obtained from milk protein and the past research studies about its production and biological activities will be explained. Second, an analysis will be made on the methods to determinate the biological activities, the separation of bioactive peptides and its structure identification. All of these form the base required to obtain synthetic peptides. Finally, we explain the experimental animal and human trials done in the past years. Nevertheless, more research is required on the design and implementation of equipment for the industrial production and separation of peptides. In addition, different authors suggest that more emphasis should therefore be given to preclinical studies, proving that results are consistent and that effects are demonstrated repeatedly by several research human groups.

Past research provided evidence of thenegative effect that individual unemployment can have on subjective well-being.The persistent high levels of unemployment and poverty in South Africa havebeen well documented. Many people are forced into the informal economy, wherethey engage in a variety of survivalist activities such as day labouring. As noprevious study has been conducted on the well-being of day labourers, the aimof this paper is to investigate the determinants of the well-being of South Africanday labourers. Objective and subjective functions are compared to determine therole of income and other variables in the well-being of day labourers. Thedeterminants are categorised according to economic, comparison and attitudinalvariables. The objective function uses income and the subjective function usesthe binary measure of experiencing a good week in terms of wages as dependentvariables. The results showed that comparison variables are importantdeterminants for the subjective measure of well-being, and attitudinalvariables are important for the objective measure of well-being. The economicvariables were important in both functions. The findings of this paper confirmother research findings showing that personal income is important for well-beingin a poor community. The difference between these functions indicates that thesubjective and objective measures of well-being both capture valuablecharacteristics of subjective well-being (SWB) in a poor community.

The Past

Past research has shown that numbers are associated with order in time such that performance in a numerical comparison task is enhanced when number pairs appear in ascending order, when the larger number follows the smaller one. This was found in the past for the integers 1–9 ( Ben-Meir, Ganor-Stern, & Tzelgov, 2013 ; Müller & Schwarz, 2008 ). In the present study we explored whether the advantage for processing numbers in ascending order exists also for fractions and negative numbers. The results demonstrate this advantage for fraction pairs and for integer-fraction pairs. However, the opposite advantage for descending order was found for negative numbers and for positive-negative number pairs. These findings are interpreted in the context of embodied cognition approaches and current theories on the mental representation of fractions and negative numbers.
