The Relationship

The General Aptitude Test Battery (GATB) is widely used to evaluate a subject’s cognitive ability for the purpose of selecting appropriate employment. The results of the GATB have been used to place staff in departments ranging from clerical departments to assembly lines. However, at actual manufacturing and assembly sites, workers receive mixed evaluations of “slow work” and “fast work” from the site administrators even though they all have high GATB scores for their jobs. In this study, with the aim of improving job design and employment selection, we do a detailed analysis of the existing GATB method of evaluating work characteristics and worker capacities. We conduct inspection ratings to measure each worker’s ability to adjust their working speeds and analyze the relationship between the GATB score and the worker evaluations. Next, we discover specific motions that explain the evaluation of workers by analyzing worker motions during the GATB. Lastly, we propose a method of determining whether an employee can work quickly in the field.

Line Design

The purpose of this paper is to demonstrate a productivity improvement through waste reduction and line balancing. One of the obstacles of a manual assembly line nowadays is an awkward line design with over manpower, a lot of wastes, and low balance efficiency. As a result, the production line may not satisfy customer demand and ends up with low production line efficiency. This is due to the fact that this type of production line is operated by human and the customer demand or requirements are frequently fluctuated. Human workers are prone to make mistakes, inefficient, and unorganized. Thus, the major causes of production line down time are discussed with suggestion of remedy actions to improve the productivity. In addition, calculation of line balancing is demonstrated. One of the actual manual assembly lines will be used as a case study. It is found that after improvement line balance efficiency is increased from 46.49 to 86.66 percent with the productivity improvement of 159 percent.

The Assembly line is the assembly process that is carried out based on the order of the production process in the production line. The problem that is often found in assembly lines is bottleneck conditions where some material piled up at the station. This situation indicates an imbalance in the production line. The improvement of the work method is one of the effective ways that can increase line efficiency. This study presents an increase in line efficiency by improving working methods in a washing machine assembly line of PT.X. The study aimed to increase the value of line efficiency by improving work methods. In this study, improvements were made using the line balancing method and Eliminate, Combine, Rearrange, Simplify (ECRS) concept. The results that have been done, the obtained value of line efficiency for washing machine products is 76.76%. This value has not reached the company's productivity target of 99.50%. Therefore it is necessary to improve the assembling line to increase the value of product production. The proposed improvements made with improvements to the work methods on the assembling line obtained 89.38% results is to increase the amount of line efficiency by improving work methods.

The Relationship

The topic of what interviews measure has received a great deal of attention over the years. One line of research has investigated the relationship between interviews and the construct of cognitive ability. A previous meta-analysis reported an overall corrected correlation of .40 ( Huffcutt, Roth, & McDaniel, 1996 ). A more recent meta-analysis reported a noticeably lower corrected correlation of .27 ( Berry, Sackett, & Landers, 2007 ). After reviewing both meta-analyses, it appears that the two studies posed different research questions. Further, there were a number of coding judgments in Berry et al. that merit review, and there was no moderator analysis for educational versus employment interviews. As a result, we reanalyzed the work by Berry et al. and found a corrected correlation of .42 for employment interviews (.15 higher than Berry et al., a 56% increase). Further, educational interviews were associated with a corrected correlation of .21, supporting their influence as a moderator. We suggest a better estimate of the correlation between employment interviews and cognitive ability is .42, and this takes us “back to the future” in that the better overall estimate of the employment interviews – cognitive ability relationship is roughly .40. This difference has implications for what is being measured by interviews and their incremental validity.

Situational Test

Advances in computer technology have created opportunities for the development of a multimedia situational test in which responses are filmed with a webcam. This paper examined the relationship of a so-called webcam test with personality, cognitive ability, job experience, and academic performance. Data were collected among 153 psychology students. In line with our expectations, scores on the webcam test, intended to measure interpersonally oriented leadership, were related to extraversion, conscientiousness, emotional stability, and job experience. Furthermore, the webcam tests significantly predicted students’ learning activities during group meetings over and above a cognitive ability test and a personality questionnaire. Overall, this study demonstrates that webcam tests can be a valid complement to traditional predictors in selection contexts.

The Relationship

The article explores the political effects of popular consultations as a means of direct democracy in struggles over mining. Building on concepts from participatory and materialist democracy theory, it shows the transformative potentials of processes of direct democracy towards democratization and emancipation under, and beyond, capitalist and liberal democratic conditions. Empirically the analysis is based on a case study on the protests against the La Colosa gold mining project in Colombia. The analysis reveals that although processes of direct democracy in conflicts over mining cannot transform existing class inequalities and social power relations fundamentally, they can nevertheless alter elements thereof. These are for example the relationship between local and national governments, changes of the political agenda of mining and the opening of new spaces for political participation, where previously there were none. It is here where it’s emancipatory potential can be found.

This article tackles the relationship between Turkish-Belgian families with the Flemish society, within the specific context of their experiences with early childhood education and care (ECEC) system in Flanders. Our findings are based on a focus group with mothers in the town of Beringen. The intercultural dimension of the relationships between these families and ECEC services is discussed using the Interactive Acculturation Model (IAM). The acculturation patterns are discussed under three main headlines: language acquisition, social interaction and maternal employment. Within the context of IAM, our findings point to some degree of separationism of Turkish-Belgian families, while they perceive the Flemish majority to have an assimilationist attitude. This combination suggests a conflictual type of interaction. However, both parties also display some traits of integrationism, which points to the domain-specificity of interactive acculturation.
