Crime, Self-Protection and Business Growth in Cote d’Ivoire  [PDF]
Assi José Carlos Kimou
Modern Economy (ME) , 2015, DOI: 10.4236/me.2015.610106
Abstract: Cote d’Ivoire was considered as an island of stability and economic prosperity in a region of stagnation, and political turmoil. The situation was reversed in the early 2000, when a decade of instability led to a surge in crime and violence. Yet, very little was known about the economic consequences of crime at the firm level. This paper tested empirically the impact of crime on business activity in Cote d’Ivoire. Using a recent World Bank enterprise survey dataset and a Heckman two-step procedure we showed that crime and private provision of security negatively impacted firms’ profit and investment.
Testing for Deterministic Components in Vector Seasonal Time Series  [PDF]
José Luis Gallego, Carlos Díaz
Open Journal of Statistics (OJS) , 2011, DOI: 10.4236/ojs.2011.13017
Abstract: Certain locally optimal tests for deterministic components in vector time series have associated sampling distributions determined by a linear combination of Beta variates. Such distributions are nonstandard and must be tabulated by Monte Carlo simulation. In this paper, we provide closed form expressions for the mean and variance of several multivariate test statistics, moments that can be used to approximate unknown distributions. In particular, we find that the two-moment Inverse Gaussian approximation provides a simple and fast method to compute accurate quantiles and p-values in small and asymptotic samples. To illustrate the scope of this approximation we review some standard tests for deterministic trends and/or seasonal patterns in VARIMA and structural time series models.
New Technique to Create a Suspension Containing Bacteriophages and How It Can Be Used to Control Cabbage Leaf Spot Caused by Xanthomonas campestris PV. campestris  [PDF]
Igor Villela Marroni, José Carlos Germani
Agricultural Sciences (AS) , 2014, DOI: 10.4236/as.2014.54031

The purpose of the present study was to develop a new method for producing and identifying a bacteriophage suspension and research its potential against plant bacteria. The suspension obtained with the new technique was effective in controlling Xanthomonas campestris PV. campestris both in vitro and in vivo. A difference was observed between the suspension with pathogen (PLP) and crude suspension with lesioned plant without the pathogen originated from it (PLN). Clear zones were observed at 48 h/28°C in both (PLS) suspension added saccharose and (PLP). Although PLP and PLS treatments showed no statistical difference in CFU values (5 × 105 and 1 × 105, respectively), they differed from the crude suspension (PLN) and the control. Then, in vivo assessment of suspensions with clear zones in the dishes was performed. In vivo (PLPS) and (PLPP) treatments consisting of inoculum were added to the crude suspensions (PLS and PLP) to increase bacteriophages. A decrease in the disease severity index compared to the control was observed, showing that treatment with the phage suspension protects the plant. The lowest disease indexes were reported with (PLP) and (PLS), with values of 1.46 and 1.40, respectively. The highest averages in dry matter (5.1 inboth treatments) were obtained with (PLP) and (PLS) treatments.

Problem Solving at Provinha Brazil: Implications of Educational Historical and Cultural Theory  [PDF]
José Carlos Miguel, V. P. Silva
Creative Education (CE) , 2015, DOI: 10.4236/ce.2015.615169
Abstract: This study discusses the methodological perspective of problem solving facing the guidelines of the Reference Matrix Literacy Mathematics Home, Provinha Brazil, and their implications for teaching practice. Leaving ample literature, it proceeds to the documentary analysis of the latest attempts to curricular reorganization in the Brazilian context, with emphasis on categories established based on the themes traditionally broadcast in the classroom. The analysis is based on categories established from the great themes of mathematical science conveyed in the initial mathematical literacy and its implications for social, political and economic. Also it addresses aspects that stand out in discussions with teachers in initial or continuing education process. Results indicate distance between the ideas discussed in Provinha Brazil and the need to establish a satisfactory relationship which allows the meanings spectrum negotiations aimed at reworking of arithmetic procedures to make them more general, less dependent on contextual variables and less subject to errors of various kinds.
Prevalence of Spinal Metastasis in Neurosurgical Procedures: A Descriptive Study  [PDF]
Jefferson Walter Daniel, José Carlos Esteves Veiga
Open Journal of Epidemiology (OJEpi) , 2016, DOI: 10.4236/ojepi.2016.64021
Abstract: Objective: This study sought to identify the prevalence of operations for spinal epidural neoplastic metastases relative to other spine and neurosurgical operative procedures. Methods: This study was descriptive and involved a retrospective review of data collected from patients who underwent neurosurgeries between February 1997 and January 2015 at a single quaternary hospital. The examined population was distributed across five descriptive categories to perform numerical distributions among neurosurgical operative procedures. Results: A total of 12,802 neurosurgical procedures were identified. These procedures were classified as follows: Skull and brain, 11,192 (87.42%); spinal column and spinal nervous tissue, 1462 (11.42%); and peripheral nerves, 148 (1.16%). Surgical procedures for the 1462 (100%) cases of spinal column and spinal nervous tissue diseases were distributed by nosology as follows: Degenerative intervertebral disk and spondylosis, 768 (52.54%); neoplastic, 279 (19.08%); traumatic, 221 (15.11%); congenital, 163 (11.14%); infectious and inflammatory, 27 (1.85%); and vascular, 4 (0.28%). With respect to the distribution of the 279 (100%) surgical procedures for spinal column and spinal nervous tissue neoplastic diseases, 124 (44.44%) procedures were for intradural neoplasms, and 155 (55.56%) procedures were for epidural spinal column neoplasms. The 155 (100%) operations for epidural neoplastic diseases were distributed into two groups: Primary epidural neoplasms, 42 (27.10%); and secondary epidural neoplasms, 113 (72.90%). Spinal column epidural neoplastic metastases (secondary neoplasms) represented 0.88% of the 12,802 neurosurgical procedures. Conclusions: Surgical procedures for spinal metastasis are uncommon with respect to all neurosurgical operative procedures. Trend analysis reveals an unchanging trend of prevalence for these procedures.
Diretrizes curriculares da pedagogia: imprecis?es teóricas e concep??o estreita da forma??o profissional de educadores
Libaneo, José Carlos;
Educa??o & Sociedade , 2006, DOI: 10.1590/S0101-73302006000300011
Abstract: the resolution of the cne (brazilian board of education) instituting national curriculum guidelines for pedagogy undergraduate courses revives the debate around the nature of pedagogical knowledge, of pedagogy courses, of licenciatura courses to train teachers and of the professional exercise of teachers and specialists in education. this paper criticizes the contents of this document pointing out that it maintains old conceptual imprecisions concerning the pedagogical field. such imprecisions do not contribute to overcome the problems that have accumulated in the legislation on the subject. this resolution thus bring little advance to enhance the quality of the brazilian basic education schools. the theoretical and prescriptive deficiencies of the resolution demand a different understanding of the concept of pedagogy. another curriculum option for the professional training of educators, be they teachers or education specialists, is thus needed.
Processo de Bolonha e ensino superior num mundo globalizado
Morgado, José Carlos;
Educa??o & Sociedade , 2009, DOI: 10.1590/S0101-73302009000100003
Abstract: deriving from a series of economic, social and cultural transformations resulting from the recent globalization surge, we analyze some of the changes that ought to take place in the field of education so that teaching institutions and teachers alike can develop teaching-learning processes guided by criteria of democracy, inclusion and justice and so that schooling may realize the expectations placed on it. since it is one of the main instruments in the production of personal, cultural and social identities, we also question the importance of curriculum in that undertaking.
Os bastidores da reforma universitária de 1968
Rothen, José Carlos;
Educa??o & Sociedade , 2008, DOI: 10.1590/S0101-73302008000200008
Abstract: this text aims to help understanding the elaboration of the university reform in 1968 and the action of one specific group, formed by some members of the federal education council, which had significant participation in the elaboration of the university reform, though this is not traditionally taken into account by researches. in order to demonstrate that, in the military government, there was some disagreement about the ways the university reform should be carried out, we make a comparison between the report produced by the meira mattos commission and the one produced by the university reform work group. we conclude that the council, or at least part of it, used its political ability to take advantage of the opportunities offered by the context and to participate, from the backstage, in the elaboration of the university model implanted brazil in the 1960s.
O dualismo perverso da escola pública brasileira: escola do conhecimento para os ricos, escola do acolhimento social para os pobres
Libaneo, José Carlos;
Educa??o e Pesquisa , 2012, DOI: 10.1590/S1517-97022011005000001
Abstract: this paper addresses the aggravation of the duality of current brazilian public schools, characterized as a school of knowledge for the rich and a school of social care for the poor. such dualism - which is perverse because it reproduces and maintains social inequalities - has obvious links not only with the educational reforms initiated in england in the 1980s, in the context of the neoliberal policies, but also and especially with the international agreements on the education for all movement, whose mark was the world conference on education for all held in jomtien, thailand in 1990, under the auspices of the world bank, the united nations development program (undp), the united nations children's fund (unicef) and the united nations educational and cultural organization (unesco). based on bibliographic research, the text argues that the association between the educational policies of the world bank for developing countries and the features of the dualistic school offers substantive explanations for the unremitting decline in the brazilian public school system over the past 30 years. at the end, the text discusses again the objectives and functions of public schools.
Para um outro arquétipo de escola: a necessidade de mudar as políticas e as práticas curriculares
Morgado, José Carlos;
Educa??o em Revista , 2010, DOI: 10.1590/S0102-46982010000200002
Abstract: the changes that have been taking place in the educational domain require greater participation of schools and communities in educational decisions and in the construction of a common pedagogical project that will articulate national goals with the needs and expectations of each community. this is what happens at the level of normative discourse. the school is expected to become a model institution that will comply with normative demands and, at the same time, ensure curriculum diversity. this implies greater autonomy for schools, continuous updating, and innovation on curriculum practices that take place within those schools. however, many changes that are 'required' of schools nowadays are determined both by decisions that come from the outside - some of which constantly postponed - and by what happens inside schools. this text presents some reflections on these issues, pointing out some ways that might contribute to the expected changes.
