An Assessment of Recovsat Utilization for Different Service Typologies
Ana Cristina Costa,Rogério Puga-Leal,Zulema Lopes Pereira
Quality Innovation Prosperity , 2012,
Abstract: This piece of research is focused on service recovery and uses the RECOVSAT instrument to obtain data from a sample of complaining customers. The study comprises three main stages. The first stage includes a descriptive analysis of the incidence and consequences of complaints in several categories of services. A Factor Analysis is performed in the second stage to compare the factor structure that emerged from the obtained data with that proposed by RECOVSAT. Finally, several regression models are used in the last stage to assess the influence of service recovery dimensions on the overall satisfaction, intention to repurchase and recommendation.
“Good Vibrations”: The Social Networks of Optimists and Alter-Optimists  [PDF]
Miguel Pereira Lopes
Social Networking (SN) , 2012, DOI: 10.4236/sn.2012.11001
Abstract: This study empirically tested if the personality trait of optimism and the interpersonal capability to generate optimism in one’s network nodes (i.e., alter-optimism) influences the social relationship patterns. The results provide evidence that optimism trait is independent from the way social networks of personal-issue sharing, advice-seeking, problem-solving, and innovation, are structured. In contrary, the alter-optimism capability does provide a good explanation of one’s social network position. Implications of these findings are discussed at the end.
A Dialectical Approach to Positive Organizational Studies  [PDF]
Miguel Pereira Lopes
American Journal of Industrial and Business Management (AJIBM) , 2013, DOI: 10.4236/ajibm.2013.32024

Over the last decade, an academic movement emerged towards the study of positive phenomena in management and organization studies. Since then, two different scientific research streams have emerged in line with this positive approach to management: 1) positive organizational scholarship (POS), which proposes a trait approach view of positive virtues and strengths and sees the environment as a moderator variable which facilitates or not the exhibition of corresponding positive behaviours; and positive organizational behaviour (POB), which defends a state-like perspective of positive characteristics, thus putting a strong emphasis on situational factors as determinants of positive behaviour, leaving a marginal role to positive psychological traits. As a critical comparison between these two different research streams is yet to be done, in this paper I propose a dialectical approach to study positivity in organizations and contrast these two different ontological approaches to positivity in organizations. I presented arguments to demonstrate that each of these approaches alone constitute quite a limited proposal in that each of them seems to misleadingly assume that: traits cannot be changed; they show incongruence between assumptions and purpose and; they constitute biased viewpoints. A dialectical approach makes possible to overcome these shortcomings by assuming both personality characteristics and environmental features relate each other in an intertwined complex way to produce positive behaviour in organizations. I finally present some practical implications that a dialectical approach would have to organizations and managers.

Calling for Authentic Leadership: The Moderator Role of Calling on the Relationship between Authentic Leadership and Work Engagement  [PDF]
Victor Seco, Miguel Pereira Lopes
Open Journal of Leadership (OJL) , 2013, DOI: 10.4236/ojl.2013.24015
Authentic Leadership (AL) literature supports the existence of a positive relationship between perceived AL, follower work engagement, and positive attitudes like calling. Our research doesn’t confirm that relationship and fosters the possibility of AL influence could not be felt by employees. It was also expected, theoretically, a positive effect of Calling as well as with trust. We have found a significant negative effect on the relationship between AL and calling. But our findings brought some positive insights. There was a positive significant relationship between calling and work engagement. Calling had also moderated, with a positive significant result, the relationship between AL and work engagement. Future research should focus on the importance of perceived AL within the education public services, and the significant effect of calling on work engagement. Our study suggests that organizations could promote employee calling work orientation, stimulate leaders to become more authentic, and improve positively organization performance.
Discovery of a young massive stellar cluster associated with IRAS source 16177-5018

Physics , 2003, DOI: 10.1086/377619
Abstract: We report the discovery of a young massive stellar cluster embedded in an extended HII region, invisible at optical wavelengths where the extinction is $A_V \approx 28$ magnitudes, associated with the IRAS source 16177-5018. $J, H$ and nb$K$ imaging photometry combined with the $K_S$ 2MASS data show the presence of sources with infrared excess emission at 2.2 $\mu$m, concentrated in an area of about one square parsec around a massive young stellar object identified as the IRAS source. This object has a near-mid infrared spectral index betweem 2.2 and 25 $\mu$m $\alpha({\rm IR}) = d {\rm log}(\lambda F_\lambda)/d {\rm log} \lambda $ =4.78, characteristic of compact H II regions, with bolometric luminosity, inferred from the integrated near to far-infrared flux density of $2.8 \times 10^5 L_\odot$, which corresponds to a ZAMS star of about $42 M_\odot$. From the color-magnitude diagram we were able to classify the majority of the cluster members as reddened massive stars earlier than spectral type B5.
Resurrection of Pareiorhaphis Miranda Ribeiro, 1918 (Teleostei: Siluriformes: Loricariidae), and description of a new species from the rio Igua?u basin, Brazil
Pereira, Edson H. Lopes;
Neotropical Ichthyology , 2005, DOI: 10.1590/S1679-62252005000200004
Abstract: a new species of the loricariid subfamily neoplecostominae is described on the basis of specimens obtained from the headwaters of the rio igua?u basin in the state of paraná, southern brazil. pareiorhaphis parmula is the first representative of the genus discovered from the rio paraná basin and expands the geographic distribution of the genus. it is diagnosed from other pareiorhaphis species by having one small plate on each side of the pectoral girdle, just posterior to the gill opening and the club-shaped pectoral-fin spine, broadening from base to tip in adult males. all species formerly included in hemipsilichthys except h. gobio, h. papillatus, and h. nimius are transferred to the genus pareiorhaphis, which is resurrected from the synonymy of hemipsilichthys.
