Background: This study investigates work-related musculoskeletal disorders risk estimation by frequently as used as ergonomic methods in the field. Objective: To identify the difference in risk estimation by an in-house observational method and a self-reported questionnaire, and to evaluate the complementary aspects of these methods. Methods: A sample of 15 operators who worked on the assembly workstations was selected from a truck manufacturing plant. The risk assessment of these workstations (28 scenarios) was performed by the observational method and the self-reported questionnaire. The agreement between both methods to identify risk situations was measured with the weighted Kappa coefficient. Results: The observational method and the self-reported questionnaire deployed on the same activity estimated different risk situations. Conclusion: This analysis does not reveal that one tool is more powerful than the other one, but shows the probability of different risk estimation. The complementary effect of each method might be considered for further investigation concerning musculoskeletal risk factors.

This paper gives emphasis to an ergonomics study conducted in a fibre insulation bay of a medium-sized air handler manufacturing plant. Work-related musculoskeletal disorders and other health problems in the fibre insulator sheets cutting operations were closely looked into. Unstructured interviews were initially conducted to uncover the underlying problems, while Direct Observation (DO) and Participative Assessment (PA) methods were utilized to identify ergonomics risk factors. Ergonomics interventions by means of real life experiments were implemented. These included 1) providing semi leather gloves to replace cotton hand gloves, 2) providing plastic chairs with back rest for occasional sitting, and 3) installing a fiberglass rolling mechanism for fiberglass cutting on table top. Post survey incorporating both DO and PA methods was subsequently conducted to gauge its effectiveness in minimizing work-related musculoskeletal disorders and other health problems. This action-oriented study finally produced fruitful results which includedinsignificant low back pain and legs ache, minimized hand irritation sensations, relieved tiredness of operators, reduced nose irritation, eye itchiness, sore throat and dizziness.

The Difference

Abstract. Two experiments tested the hypothesis that self-evaluation can serve as a source of interpersonal attitudes. In the first study, self-evaluation was manipulated by means of false feedback. A subsequent learning phase demonstrated that the co-occurrence of the self with another individual influenced the evaluation of this previously neutral target. Whereas evaluative self-target similarity increased under conditions of negative self-evaluation, an opposite effect emerged in the positive self-evaluation group. A second study replicated these findings and showed that the difference between positive and negative self-evaluation conditions disappeared when a load manipulation was applied. The implications of self-evaluation for attitude formation processes are discussed.

Kunst kann dann als reflexiv interpretiert werden, wenn Reflexivität nicht auf propositionalen Gehalt oder sogar sprachliche Artikulation angewiesen ist. Reflexion tritt auf in den Modi der Selbstbeziehung des Lebendigen, des Überlegens und der Selbstreferenz im Symbolischen. Kunst ist ein Reflexionsmedium, das diese Modi beansprucht und miteinander verflicht. Eine spezifisch ästhetische Reflexivität ist von und nach Kant nach dem Vorbild der transzendentalen Reflexion und in Konkurrenz zu ihr etabliert worden. Sie läßt sich als Reflexivität des ästhetischen Urteils, als emphatisches Gemachtsein, als Rückwendung auf Wahrnehmungsvollzüge oder als Begriffsreflexion verstehen. Dabei wird die Unterscheidung von Anschauung und Verstand in deren Zusammenspiel oder Abspaltung vorausgesetzt. Von der Analogie zur transzendentalen Reflexion löst sich aber erst ein Verständnis von ästhetischer Reflexivität, das von den drei Modi und ihrer Verflechtung ausgeht.<br><br>Reflexivity does not presuppose linguistic articulation or even propositional content. If it did, art could not be called reflexive. Reflexivity can be found in the self-contact of the living, in mental reflection or in symbolic self-reference. Art is a medium which claims these different modes of reflexivity and intertwines them. Aesthetic reflexivity as such has been established by Kant and his epigones, following the model of transcendetal reflection. Thus it could be specified as the reflexive structure of aesthetic judgement, or as an emphasis on a work’s being created, or as a reference to perception itself in the process of perceiving, or as a way of reflecting concepts. Aesthetic reflexivity can only be detached from the model of transcendental reflection, if it is seen as oriented towards the interaction among the three modes of reflection mentioned above, leaving aside the difference, interplay or competition between perception and conceptual capacities.
