Detection And Quantification

Abstract Food laboratories have developed methods for testing allergens in foods. The efficiency of qualitative and quantitative methods is of prime importance in protecting allergic populations. Unfortunately, food laboratories encounter barriers to developing efficient methods. Bottlenecks include the lack of regulatory thresholds, delays in the emergence of reference materials and guidelines, and the need to detect processed allergens. In this study, ultra-HPLC coupled to tandem MS was used to illustrate difficulties encountered in determining method performances. We measured the major influences of both processing and matrix effects on the detection of egg, milk, soy, and peanut allergens in foodstuffs. The main goals of this work were to identify difficulties that food laboratories still encounter in detecting and quantifying allergens and to sensitize researchers to them.

The Status

Urban poverty is one of multidimensional issue in Nepal. Increasing immigration from the outer parts of Kathmandu due to rural poverty, unemployment and weak security of the lives and the properties are core causes pushing people into urban areas. In this context how squatter urban area people sustain their livelihoods is major concern. The objectives of the study are to find out livelihood assets and capacities squatters coping with their livelihood vulnerability in adverse situation. Both qualitative and quantitative methods are applied for data collection. It is found that squatters social security is weak, victimized by severe health problems earning is not regular with lack of physical facilities and overall livelihood is critical. This study helps to understand what the changes that have occurred in livelihood patterns and how poor people survive in urban area.

Beliefs And Attitudes

Qualitative research is a primary way to understand the context of diabetes in a person′s life, beyond the medical outcomes. Identifying the qualitative issues such as patients′ knowledge about diabetes, their beliefs and attitudes, and their relationship with health care professionals can serve as data to determine the obstacles and, in turn, resolutions to those issues in diabetes management. Characteristics of qualitative and quantitative methods are described, with the discussion that both methods are complementary, not conflicting, to further the field of diabetes research.

The Impact

Nepotism and cronyism are forms of favoritism towards certain people in the workplace. For this reason, they constitute a problem for organization managers, ethicists and psychologists. Identifying the impact of COVID-19 pandemic on the increase of nepotism and cronyism may provide a basis for organizations to assess their extent and to take possible measures to prevent their negative effects. At the same time, the research presented in the article may provide a basis for further research work related to nepotism and cronyism at the times of other threats, different from the pandemic. The aim of the article is to examine the impact of the COVID-19 pandemic on growing acceptance for nepotism and cronyism in Polish enterprises. Qualitative and quantitative methods have been included in the conducted research. Qualitative study aimed at improving knowledge of nepotism and cronyism and the impact of the COVID-19 pandemic on these phenomena, followed by a quantitative study conducted in order to verify the information obtained in the qualitative study. This research has demonstrated that Nepotism and cronyism in the workplace, are phenomenon that are basically evaluated negatively. They adversely influences social and economic development, but the impact of COVID-19 pandemic on nepotism and cronyism is not significant.

Kinship care as a formal placement option has been steadily increasing over recent years, particularly in New South Wales. This paper draws on a report of research on kinship care in New South Wales, in which the two authors participated (Mason et al, 2002). In conducting the research, qualitative and quantitative methods were used to explore both ‘top down’ perspectives (from policy documents and statistics) and ‘bottom up’ perspectives (from child protection practitioners and those who experience policy as service recipients – kinship carers, young people in kinship care and parents of children in kinship care).In this paper we briefly outline the research and discuss findings relating to definitions of kinship care, the extent of kinship care in NSW, decision making around the placement of children in kinship care, reasons given by participants for kinship care, and support for carers.

Complex of measurements methods for indicate white efflorescence are presented in this paper. This article is focus on primary efflorescence, specifically lime based, which cannot be completely avoided. Tests involve not only qualitative and quantitative methods but also recommended additional measurement. Because there are not any standard for determination this kind of efflorescence, this set of tests should help for design concrete elements and limited risks of its creation.

Assessment is an integral part of measuring effectiveness of teaching and learning processes. It basically focused on measuring the students’ progress in what they learned. Current study examined the relation between the students’ perceptions towards EFL teachers Classroom Assessment methods and their academic achievements. To this end, descriptive research design with qualitative and quantitative methods of data collections was employed. Data were collected from primary and secondary sources via questionnaire, interview and observations. Target populations of current study were randomly selected 281students and purposely selected four teachers of secondary schools at Wolaita zone, Ethiopia. The data were analyzed using mixed methods of data analysis. Based on results obtained from qualitative and quantitative data, it was found out that the students’ perceptions towards teachers’ assessment was proportional to their achievement. Most dominantly, low achievers were not satisfied with their teachers’ methods of assessment as their students were low and the vice versa it true.
