Employee Candidate Selection Systems Based on Web

The success of a school, of course, cannot be separated from the roles of teachers and employees. With the presence of teachers who meet predetermined quality standards, the school's productivity will increase and its quality can be maintained. Therefore, the school is required to be able to select a more objective recruitment of prospective employees. A process that is not objective will lead to inaccuracy in selecting prospective employees. To overcome this problem, a candidate recruitment application system is needed that can select prospective employees as needed. This research took place in private high schools in Jakarta. The system development method used in this research is the waterfall. The application developed in this study consisted of three users, namely the principal, assessors and prospective employees. This study produces an application that can be used by the private high school in selecting prospective employees according to their needs.

A facile platform to engineer E. coli tyrosyl-tRNA synthetase adds new chemistries to the eukaryotic genetic code, including a phosphotyrosine mimic

The E. coli tyrosyl-tRNA synthetase (EcTyrRS)/tRNAEcTyr pair offers an attractive platform to genetically encode new noncanonical amino acids (ncAA) in eukaryotes. However, challenges associated with a eukaryotic selection system, which is needed for its engineering, has impeded its success in the past. Recently, we showed that EcTyrRS can be engineered using a facile E. coli based selection system, in a strain where the endogenous tyrosyl pair has been substituted with an archaeal counterpart. However, a significant cross-reactivity between the UAG-suppressing tRNACUAEcTyr and the bacterial glutaminyl-tRNA synthetase limited the scope of this strategy, preventing the selection of moderately active EcTyrRS mutants. Here we report an engineered tRNACUAEcTyr that overcomes this cross-reactivity. Optimized selection systems using this tRNA enabled efficient enrichment of both strongly and weakly active ncAA-selective EcTyrRS mutants. We also developed a wide-dynamic range (WiDR) antibiotic selection to further enhance the activities of the weaker first-generation EcTyrRS mutants. We demonstrated the utility of our platform by developing several new EcTyrRS mutants that efficiently incorporate useful ncAAs in mammalian cells, including photo-affinity probes, bioconjugation handles, and a non-hydrolyzable mimic of phosphotyrosine.

Exams or applications? Elite Taiwanese students’ perceptions and navigation of college admissions systems

Studies often portray elite students as self-interested adolescents who justify educational selection systems that favor them. However, this perspective neglects critiques of the college admissions system on the part of the elite, who often have no other option than to support it as fulfilling the ideals of fairness. This study examines academic elite students’ perceptions of college admissions systems when they are given choices as to which system to use. Data for this study come from surveys, interviews, and participant observation in Taiwan, where students are selected through two systems: exam-based selections and application-based selections. The findings show that students in elite high schools perceive whichever system that benefits them to be the fairest. By narrowly defining fairness as family influence on admission outcomes, these students downplay the institutional advantages they enjoy and present themselves as deserving candidates. Using the example of elite Taiwanese students, this study highlights that elites justify privilege based on self-interest and strategically navigate admissions systems to accrue advantages.

Evaluating Foreign Skills: Effects of Credential Assessment on Skilled Immigrants’ Labour Market Performance in Canada

Formal educational qualification is increasingly built into immigrant selection systems in many countries, but in a global context, the transferability and portability of such qualifications has been questioned. In 2013, Canada introduced the requirement for a formal assessment of educational credential equivalence for applicants in the skilled worker category. In this study, we use a Canadian national immigration database and difference-in-differences methodology to investigate whether requiring formal Educational Credential Assessment (ECA) as part of the selection process for skilled immigrants has improved labour market outcomes. Our results indicate that the ECA requirement is positively related to early employment rates and earnings for both men and women. However, this effect is limited to those with no previous employment experience in Canada. We also find that, even with the ECA requirement, significant differences in the earnings of immigrants from different source regions remain. Implications and recommendations are discussed.

Engineering Threshold-Based Selection Systems

Using model organisms to identify novel therapeutic targets is frequently constrained by pre-existing genetic toolkits. To expedite positive selection for identification of novel downstream effectors, we engineered conditional expression of activated CED-10/Rac to disrupt C. elegans embryonic morphogenesis, titrated to 100% lethality. The strategy of engineering thresholds for positive selection using experimental animals was validated with pharmacological and genetic suppression and is generalizable to diverse molecular processes and experimental systems.

Location Selection Query in Google Maps using Voronoi-based Spatial Skyline (VS2) Algorithm

Google Maps is one of the popular location selection systems. One of the popular features of Google Maps is nearby search. For example, someone who wants to find the closest restaurants to his location can use the nearby search feature. This feature only considers one specific location in providing the desired place choice. In a real-world situation, there may be a need to consider more than one location in selecting the desired place. Assume someone would like to choose a hotel close to the conference hall, the museum, beach, and souvenir store. In this situation, nearby search feature in Google Maps may not be able to suggest a list of hotels that are interesting for him based on the distance from each destination places. In this paper, we have successfully developed a web-based application of Google Maps search using Voronoi-based Spatial Skyline (VS2) algorithm to choose some Point Of Interest (POI) from Google Maps as their considered locations to select desired place. We used Google Maps API to provide POI information for our web-based application. The experiment result showed that the execution time increases while the number of considered location increases.

Molecular Portrait of an Athlete

Sequencing of the human genome and further developments in “omics” technologies have opened up new possibilities in the study of molecular mechanisms underlying athletic performance. It is expected that molecular markers associated with the development and manifestation of physical qualities (speed, strength, endurance, agility, and flexibility) can be successfully used in the selection systems in sports. This includes the choice of sports specialization, optimization of the training process, and assessment of the current functional state of an athlete (such as overtraining). This review summarizes and analyzes the genomic, proteomic, and metabolomic studies conducted in the field of sports medicine.
