Organizational sacralization and discursive use of corporate mission statements

Abstract: The religious origin of organizational behavior is not easy to recognize, nor are the implications of the Christian heritage of concepts and ideas as applied to organizations. This paper seeks to remedy this by investigating the theological roots of the mission concept. Our central argument is that corporate mission statements are sometimes used as manipulative communicative tools which seek organizational legitimacy through the rhetorical inclusion of secularized Christian values. We find in Koselleck's (1985) Conceptual History theoretical arguments by which to evaluate the bridge between theological and corporate concepts of mission. Then, we discuss mission as a theological concept, showing how it developed in modern societies and how its discursive use in business can be evaluated. With an analysis based on Habermas' (1985) work, we conclude that, as a communicative tool, a corporate mission statement helps organizations manipulate meanings about their purposes and legitimacy in Christianity-based societies. This process reveals how the mission concept contributes to increase organizational sacralization and represents a powerful tool for improving a corporation's social image and as a consequence may induce social consent.

Isolation and characterization of the nematophagous fungus Arthrobotrys conoides.

Abstract: The spread of organic farming and the development of resistance to anthelmintics by parasites, especially in small ruminants, have necessitated the search for alternative methods of nematode control. Biological control using nematophagous fungi is one option; however, few studies have been conducted with native strains. The present study was divided into two phases. In the first phase, we aimed to isolate, identify, and assess the in vitro predatory activity of nematophagous fungi that had been isolated on Trichostrongylidae third-instar larvae. In the second phase, the isolate with superior predatory activity in vitro was molecularly characterized, and its morphological plasticity was observed using scanning electron microscopy (SEM) on Haemonchus third-instar larvae. Of the 56 soil samples from different regions of Parana State, Brazil, 57 fungal strains were recovered, of which four exhibited predatory activity. Two pure isolates were obtained: the CED and LIN strains. After demonstrating 96.35 % predatory activity for the CED strain, this strain was selected and characterized using molecular criteria by sequencing the rDNA internal transcribed spacer and was identified as Arthrobotrys conoides (GenBank ID: JN191309). Morphological patterns in this strain during the interaction between the fungus and the nematode were revealed by SEM, in which two extensions of the infection bulb that was used to pierce the nematode's cuticle were clearly visible.

Thermoanalytical and starch content evaluation of cassava bagasse as agro-industrial residue

Abstract: As fracoes nutricionais bem como as propriedades termicas e outras analises sao essenciais para a industria de alimentos e suas aplicacoes O bagaco de mandioca e um importante residuo agroindustrial e seu teor de amido foi avaliado por dois metodos alternativos. A caracterizacao por analise termica e microscopia ajudou na compreensao de como a hidrolise digere a fracao amilacea do bagaco de mandioca, O ponto de fusao foi de 170oC, a analise termogravimetrica (TG) mostrou apos a perda de umidade do material, duas principais perdas de massa em todas as amostras analisadas. Os resultados sugerem que a hidrolise enzimatica e menos eficiente na conversao total de amido no bagaco de mandioca. No entanto, o uso de acido sulfurico degradou ate mesmo a parcela fibrosa do material, afetando as condicoes de analise.

Retention of laparoscopic skills in naive medical students who underwent short training

Abstract: Simulators are useful tools in the development of laparoscopic skills. However, little is known about the effectiveness of short laparoscopic training sessions and how retention of skills occurs in surgical trainees who are naive to laparoscopy. This study analyses the retention of laparoscopic surgical skills in medical students without prior surgical training. A group of first- and second-year medical students (n = 68), without prior experience in surgery or laparoscopy, answered a demographic questionnaire and had their laparoscopic skills assessed by the Fundamentals of Laparoscopic Surgery (FLS) training protocol. Subsequently, they underwent a 150-minute training course after which they were re-tested. One year after the training, the medical students’ performance in the simulator was re-evaluated in order to analyse retention. Of the initial 68 students, a total of 36 participated throughout the entire study, giving a final participation rate of 52 %. Thirty-six medical students with no gender predominance and an average age of 20 years were evaluated. One year after the short training programme, retention was 69.3 % in the peg transfer (p < 0.05) and 64.2 % in ligature (p < 0.05) compared with immediate post-training evaluation. There was no significant difference in suturing. The average sample score in the baseline test was 8.3, in the post-training test it was 89.7, and in the retention test it was 84.2, which corresponded to a skill retention equivalence of 93 %. There was a significant retention of the laparoscopic surgical skills developed. Even 1 year after a short training session, medical students without previous surgical experience showed that they have retained a great part of the skills acquired through training.
