Abstract
Micro and Small Enterprises have assumed an important strategic role for the economic and social development of Brazil, representing about 99% of all business establishments and contributing to the generation of 55.3% of all formal jobs in the country. However, these ventures have faced a series of restrictions on entrepreneurial activity, such as low government support, high taxes, and excessive bureaucracy. In this adverse context, innovation assumes a significant mediation role for increasing business performance and, consequently, maintaining the permanence of these ventures in the market. Accordingly, the present investigation aimed to identify the degree of innovation, the main obstacles and facilitators of innovation, as well as the types of innovation prevalent in Brazilian Micro and Small Enterprises through a systematic literature review. The literature review included 21 articles extracted from the Web of Science, Scopus, Scielo, and Spell databases. In general, the analyzed literature points out that innovation in these ventures is the result of simple actions, such as imitation and the acquisition of technology from third parties, and that the degree of innovation is low, prevailing in the types of innovation in Products and Marketing. The main barriers highlighted were related to the lack of resources, precarious managerial and commercial capacities, and shortages of qualified labor, while the factors that facilitate innovation are related to the support of government programs and the organization of Micro and Small Enterprises in productive arrangements.

Abstract
PurposeThis study aims at validating a scale for the perception of competences and attitudes of the Portuguese public administration employees. The sample of this study consists of 1,119 participants working in public administration and other labour sectors in Portugal. The psychometric qualities of this instrument were studied to assess its use in future studies. Design/methodology/approachAn initial exploratory factor analysis showed that the scale is composed of one factor, with a Kaiser-Meyer-Oklin value of 0.83. The subsequent confirmatory factor analysis performed in AMOS 27 confirmed the existence of a single factor. FindingsThe analysis of the psychometric qualities of the scale allows concluding that it can be applied in the context of the Portuguese public administration. Originality/valueGiven the universality of the competences and attitudes adopted, it can be extended to other work and cultural contexts.

Abstract
Negative organizations, where powerful people manage to keep a negative strategy in place, one which does not benefit the firm but perpetuates their power, is a reality discussed herein. Positive organizations, led by positive leaders who do not feel threatened by brilliant employees who have brilliant ideas, may be less prominent than we think and should not be taken for granted. Following thirty years of working in organizations, both large and small, the author has come to realize that the status quo tends to be very strong, and that innovating and disrupting that balance is not only dangerous but seldom succeeds. More research is necessary in this field to prove this theory right. This article aims to point readers and researchers in the right direction and to challenge one to think just how negative organizations may be. The article is based on the experience of the author; on a look at the case of Nokia (the former handheld mobile phone division), seen to be a negative organization; as well as on in-depth personal interviews with three experts (a purposive sample) on the topic of positive versus negative organizations; and, finally, the results of two surveys (n = 116—millennials; and n = 115—Generation Z) are shared. A total of 94.8% of the Generation Z respondents (109 respondents in total) believe negative organizations to exist (where the status quo may prevail over innovative individuals and innovation to the detriment of the global organizational strategy), which is seen to be very encouraging for this research study.

Abstract
Nowadays, and increasingly, Artificial Intelligence (AI) occupies a leading role in the world, being used in the most diverse contexts. The retail sector is just one of them. The starting question that originated this article is: is Portugal receptive to the use of cutting-edge Artificial Intelligence in retail? In other words, what is the opinion of the Portuguese and residents in Portugal, as consumers, regarding the use of automation by retail companies? Based on the analysis of the answers to an online questionnaire (which obtained 132 answers), we will present our conclusions regarding this matter. The goal is to understand if Portuguese people / residents in Portugal are willing and interested in going to supermarkets like Amazon Go or Continente Labs (or Pingo Doce & GO NOVA). In addition, it is intended to understand the reasons that lead them to respond skeptically, so that, in the future, strategies may be initiated by the companies of the sector, which based on greater and better education, may clarify, and perhaps change their assumptions and convictions. The results of this study reveal that the Portuguese and residents in Portugal are not yet interested in using automated supermarkets, showing some mistrust and reticence towards this new technology, although they recognize that it can increase the speed and efficiency of the service. In fact, of the 37,1% of respondents that consider it quite attractive, about 84% believe it may have a significant impact on the reduction of time spent shopping.
