O momento, os desafios e as possibilidades da análise econômica territorial para o planejamento do desenvolvimento nacional

O artigo pretende contribuir para a superação dos desafios relativos à capacidade de análise e de atuação para o desenvolvimento regional e territorial. Para tanto, discute a relação entre conhecimento e planejamento - entre ciência e ação baseada em ciência. Após uma análise dessa relação, no período anterior à prevalência da tese da New Public Management, na qual deverão ser investigadas as condições que levaram ao fracasso das estratégias do planejamento do desenvolvimento no pós-guerra, pergunta-se se se observa, desde então, evolução nas ciências da sociedade que possa oferecer base ao planejamento de um desenvolvimento fundamentado em crescimento, equidade e sustentabilidade. A partir daí, explora-se a possibilidade de as teorias do desenvolvimento endógeno e sustentável (TDES) subsidiarem novos processos de planejamento. Nessa tarefa, o foco principal é posto nas noções de clustering, de trajetórias tecnológicas, de cadeias de valor, de economias locais e regional.

Um grego agora nu: índios marajoara e identidade nacional brasileira

O objetivo dessa tese é analisar a disseminação do simbolismo marajoara oriundo das peças arqueológicas encontradas na ilha do Marajó. A base documental dessa pesquisa é constituída por fontes do século XIX publicadas na revista do Museu Nacional do Rio de Janeiro, além de jornais do século XX. Da ciência, o simbolismo marajoara passou a ser utilizado na arte, na arquitetura, na indumentária, nos espaços públicos e privados. No artesanato, a ressignificação da cultura material é recorrente até os dias atuais. Concluiu-se que, de meros cacos encontrados em sítios arqueológicos, a cerâmica marajoara foi revestida de valores que a enobreceram, sendo espetacularizada como emblema da identidade nacional brasileira.

Genomic selection and assisted reproduction technologies to foster cattle breeding

Genomics has been propagated as a paradigm shifting innovation in livestock during the last decade. The possibility of predicting breeding values using genomic information has revolutionized the dairy cattle industry and is now being implemented in beef cattle. In this paper we discuss how genomics is changing cattle breeding through genomic selection, and how this change is creating new ways to articulate assisted reproduction technologies with animal breeding. We also debate that the scientific community is still starting the long journey to reveal the functional aspects of the cattle genome, and that knowledge in this field is the frontier to a whole new venue for the development of novel applications in the livestock sector.

Relationships between growth of the preovulatory follicle and gestation success in lactating dairy cows

This report summarizes three studies conducted with lactating dairy cows aiming to increase pregnancy rates to fixed time artificial insemination (TAI) protocols. Experiment 1 was designed to determine if changing the timing of PGF2 alpha treatment during an E2/P4-based program would affect fertility to TAI or fixed-time embryo transfer (TET). In experiment 2, pregnancy rates to AI were compared following synchronized ovulation using two protocols that have been developed to reduce the period between follicular wave emergence and TAI. The Ovsynch-type protocol utilizes GnRH to synchronize the follicular wave by inducing ovulation of a dominant follicle at the beginning of the protocol, and to synchronize ovulation at the end of the protocol allowing TAI. In contrast, E2/P4-based protocols utilize E2 products in the presence of P4 to induce atresia of antral follicles and synchronize emergence of a new follicular wave. At the end of E2/P4-based protocol another E2 treatment in the absence of P4 is used to induce LH release and synchronize ovulation and allow TAI. Experiment 3 was designed to determine whether increasing the length time interval with reduced circulating P4 (proestrus) would increase fertility in a TAI program that utilized E2 and P4 to synchronize ovulation of cycling, lactating dairy cows. The overall conclusions are that circulating concentrations of progesterone and estradiol prior to and circulating concentrations of progesterone following ovulation can affect fertility in cattle. In addition, small increases in P4 concentrations near the time of AI, due to lack of complete CL regression, result in reductions in fertility. Earlier treatment with PGF2 alpha should allow greater time for CL regression, an increase in estradiol and subsequent reductions in circulating P4 that could be critical for fertility. Optimization of follicle size in TAI programs is clearly an intricate balance between oocyte quality, adequate circulating E2 near AI, and adequate circulating P4 after AI.

Improving postcryopreservation survival capacity: an embryo-focused approach

The major challenge for a greater dissemination of in vitro produced (IVP) bovine embryos is to improve embryonic survival after cryopreservation. The involvement of embryonic lipids on this issue is well documented. However, it has been recognized that not only the amount of lipids that affects embryo cryotolerance, but the embryo survival capacity after cryopreservation is a rather multifactorial event. In this review, some strategies to improve embryonic lipid composition and postcryopreservation survival by modifying the embryos themselves to make them more cryopreservable are overviewed. The use of semi-defined and defined serum-free culture media, the addition of some chemicals in the culture media to modify embryo lipid composition, and the modulation of embryo cell membrane fluidity by cholesterol or unsaturated fatty acids added to the culture media and oocyte/embryo donor nutritional management with a diet enriched in polyunsaturated fatty acids, were described as alternatives for the improvement of IVP embryo survival after cryopreservation.

A comparison of microbiological and molecular detection of vaginal Lactobacillus spp. between mares and women

A possible explanation for endometritis in mares is ascendant contamination from the vagina. The presence of Lactobacillus spp. is considered to be important in women for a healthy vaginal environment; however, there are few studies in mares related to the presence of Lactobacillus in the vaginal flora of healthy mares. The present work aims to determine the occurrence of Lactobacillus spp. in the vaginal micro-environment of mares. A total of 35 crossbred multiparous mares, aged between 4 and 12 years, with no history of reproductive problems and with healthy reproductive tracts, were used. Two vaginal swabs were obtained from the mares during estrus for Lactobacillus isolation and PCR evaluation. Ten human female volunteers, aged between 24 and 35 years, sexually active, with no history of gynecological diseases and treatments in the past two years were used. Lactobacillus spp. were isolated from 5.7% of the mares' vaginal samples and from 90% of the women's vaginal samples. Lactobacillus DNA was detected by PCR in 22.9% of the mares' vaginal samples and in all of the vaginal samples from the healthy women. The primers used here were demonstrated to have in silico specificity for the detection of L. equi (AB425924.1), L. pantheris (DQ471798.1) and L. mucosae (DQ471799.1), but they did not anneal on Enterococcus faecalis (EU887827.1) or E. faecium (EU887814.1). In conclusion, this study showed a low occurrence of Lactobacillus spp. in mares, suggesting that this bacterium may not play a fundamental role in the equilibrium of the vaginal micro- environment of normal mares.

Safety performance models for urban intersections in Brazil

This paper presents a modeling effort for developing safety performance models (SPM) for urban intersections for three major Brazilian cities. The proposed methodology for calibrating SPM has been divided into the following steps: defining the safety study objective, choosing predictive variables and sample size, data acquisition, defining model expression and model parameters and model evaluation. Among the predictive variables explored in the calibration phase were exposure variables (AADT), number of lanes, number of approaches and central median status. SPMs were obtained for three cities: Fortaleza, Belo Horizonte and Brasilia. The SPM developed for signalized intersections in Fortaleza and Belo Horizonte had the same structure and the most significant independent variables, which were AADT entering the intersection and number of lanes, and in addition, the coefficient of the best models were in the same range of values. For Brasilia, because of the sample size, the signalized and unsignalized intersections were grouped, and the AADT was split in minor and major approaches, which were the most significant variables. This paper also evaluated SPM transferability to other jurisdiction. The SPM for signalized intersections from Fortaleza and Belo Horizonte have been recalibrated (in terms of the COx) to the city of Porto Alegre. The models were adjusted following the Highway Safety Manual (HSM) calibration procedure and yielded C-x of 0.65 and 2.06 for Fortaleza and Belo Horizonte SPM respectively. This paper showed the experience and future challenges toward the initiatives on development of SPMs in Brazil, that can serve as a guide for other countries that are in the same stage in this subject.
