Setor informal: um estudo sobre os camelôs do Shopping Popular em Cuiabá - MT/2003

The phenomenon of the informality has been common in the quarrels that involve Sciences Social and Human. First for not corresponding to a temporary and isolated phenomenon, and on the other hand for dealing with a presente situation in the majority of the Brazilian urban centers. In Cuiabá municipality, the alternative commerce appears as a social answer to the problems caused for the economic crisis of the country and seems to be deep-rooted to the urban landscape. This assignment angles was the street peddlers, in special that ones who develop their in a specific location on lowered of Cuiabá. Researches pretending to fill a blank of information about this subject involve theoritical and empirical levels. The theory searched to raise in a generalized manner given pertinent the informality and the pratical level through field research searched to analyze excellent aspects on the economic and occupational situation of a composed sample for two hundred and theree workers who develope the pratical one of the informal commerce in Shopping Popular in Cuiaba/MT. The analysis of gotten data alllowed to appreciate some excellent aspects with regard to the activity os the peddler, as: origni, formation, income, perspectives with regard to activity among others. In las analysis it still alllowed to verify the factors that condition the permanence these workers in this type of informal activity

Can we predict agitation in patients with suicide attempts in the emergency department?

Background: The agitation in patients presenting to the emergency department (ED) after suicide attempts is common and an important problem. Objective: To establish whether we can predict agitated patients among suicide attempt patients in ED. Methods: This is a cross-sectional observational study of adult suicide attempt events in ED. Information was collected prospectively on a specially designed data-collection form. Patients aged 16 years old and above who presented to the ED for care due to suicide attempts were included in the study. Suicide attempts were grouped as aggressive and non-aggressive attempts. Results: A total of 533 patients were included. Forty-three of these patients had agitation in ED (8%). Non-aggressive suicide attempts were referred to psychiatry services more than aggressive ones (73.6%, n=345 vs 32.8%, n=21, P<0.0001). Agitation in ED and being male increased aggressive suicide attempt risk 3.5 (95% CI:1.6-7.6) and 3.2 times (95% CI:1.8-5.5), respectively. Agitation was statistically more frequent among these patients: those on antidepressant overdose, with previous suicide attempt; with aggressive suicide attempt; and those with confusion; and unconsciousness (P<0.05). Conclusion: Patients who attempted suicide and whose risk of harm to others included those with: antidepressant overdose, aggressive suicide attempt and the unconscious. Response teams should be prepared for these subgroups.

Short Term Outcome of Neonates Born With Abnormal Umbilical Cord Arterial Blood Gases

Background: Umbilical arterial blood gas (UABG) analysis is more objective than other methods for predicting neonatal outcome. Acidemic neonates may be at risk for unfavorable outcome after birth, but all neonates with abnormal arterial blood gas (ABG) analysis do not always have poor outcome. Objectives: This study was carried out to determine the short term outcome of the neonates born with an abnormal ABG. Patients and Methods: In a cohort prospective study 120 high risk mother-neonate pairs were enrolled and UABG was taken immediately after birth. All neonates with an umbilical cord pH less than 7.2 were considered as case group and more than 7.2 as controls. Outcomes like need to resuscitation, admission to newborn services and/or NICU), seizure occurrence, hypoxic ischemic encephalopathy (HIE), delayed initiation of oral feeding and length of hospital stay were recorded and compared between the two groups. P value less than 0.05 was considered as being significant. Results: Comparison of short term outcomes between normal and abnormal ABG groups were as the fallowing: need for advanced resuscitation 4 vs. 0 (P = 0.001), NICU admission 16 vs. 4 (P = 0.001), convulsion 2 vs. 0 (P = 0.496), HIE 17 vs. 4 (P = 0.002), delay to start oral feeding 16 vs. 4 (P = 0.001), mean hospital stay 4 vs. 3 days (P = 0.001). None of the neonates died in study groups. Conclusions: An umbilical cord PH less than 7.2 immediately after birth can be used as a prognostic factor for unfavorable short term outcome in newborns.

Prevalence of Listeria species in some foods and their rapid identification

Purpose: To investigate the occurrence of Listeria spp., (particularly L. monocytogenes ), in different foods and to compare diagnostic tools for their identification at species level. Methods: Samples of high protein foods such as raw meats and meat products and including beef products, chicken, fish and camel milk were analysed for the presence of Listeria spp. The isolates were characterised by morphological and cultural analyses, and confirmed isolates were identified by protein profiling and verified using API Listeria system. Protein profiling by SDS-PAGE was also used to identify Listeria spp. Results: Out of 40 meat samples, 14 (35 %) samples were contaminated with Listeria spp., with the highest incidence (50 %) occurring in raw beef products and raw chicken. Protein profiling by SDSPAGE was used to identify Listeria spp. The results were verified with API Listeria system. Approximately 25 % of the identified isolates were Listeria seeligeri , Listeria welshimeri , and Listeria grayi (three positive samples), while 16.66 % of the isolates were Listeria monocytogenes (two positive samples); 16.6 % of the isolates were Listeria innocua (two positive samples), while 8.3 % of the isolates were Listeria ivanovii (one positive sample). Conclusion: High protein foods contain different types of Listeria species; whole-cell protein profiles and API Listeria system can help in the identification of Listeria at the species level.

La sabiduría árabe antigua reflejada en los proverbios de Al-Maydani: traducción y análisis paremiológico de un corpus seleccionado

Little is known about Ancient Arabia before the arrival of Islam as it was an area with few inhabited settlements and it was mostly a passageway for traders. In those inhabited settlements we could find some settled Arabs, but the prevailing life style was that of the rest of the population, nomadic Bedouin Arabs who travelled from place to place looking for water and pasture for their cattle, which they lived off. The desert was their natural habitat, a hostile environment full of danger where life was not easy. Camel taming made it possible for them to live that nomadic lifestyle, and the Bedouins became inseparable from their camels and from their horses and cattle. In order to make a living they worked as hunters, transported caravans, and plundered too. In the pre-Islamic era, knowledge was transmitted by oral communication, so very little written information about that time and place remains. One thing that has been handed down are proverbs, which after the 8th Century started to be collected by several writers in various written works. Given the characteristics of those proverbs, which are conserved almost intact from their origins, we can learn much about the lifestyle in Ancient Arabia. What is to be investigated within this thesis is whether through Paremiology it is possible to learn more about this area at this historic moment that precedes the arrival of Islam, and the first years of this religion. To learn about history, we usually rely on historians and palaeontologists, but this work will demonstrate that through Paremiology it is possible to know other aspects of culture, their knowledge, the way of life, thinking, society, etc...

Efficient algorithms for beacon routing in polygons

In a paper by Biro et al. [7], a novel twist on guarding in art galleries is introduced. A beacon is a fixed point with an attraction pull that can move points within the polygon. Points move greedily to monotonically decrease their Euclidean distance to the beacon by moving straight towards the beacon or sliding on the edges of the polygon. The beacon attracts a point if the point eventually reaches the beacon. Unlike most variations of the art gallery problem, the beacon attraction has the intriguing property of being asymmetric, leading to separate definitions of attraction region and inverse attraction region. The attraction region of a beacon is the set of points that it attracts. For a given point in the polygon, the inverse attraction region is the set of beacon locations that can attract the point. We first study the characteristics of beacon attraction. We consider the quality of a "successful" beacon attraction and provide an upper bound of $\sqrt{2}$ on the ratio between the length of the beacon trajectory and the length of the geodesic distance in a simple polygon. In addition, we provide an example of a polygon with holes in which this ratio is unbounded. Next we consider the problem of computing the shortest beacon watchtower in a polygonal terrain and present an $O(n \log n)$ time algorithm to solve this problem. In doing this, we introduce $O(n \log n)$ time algorithms to compute the beacon kernel and the inverse beacon kernel in a monotone polygon. We also prove that $\Omega(n \log n)$ time is a lower bound for computing the beacon kernel of a monotone polygon. Finally, we study the inverse attraction region of a point in a simple polygon. We present algorithms to efficiently compute the inverse attraction region of a point for simple, monotone, and terrain polygons with respective time complexities $O(n^2)$, $O(n \log n)$ and $O(n)$. We show that the inverse attraction region of a point in a simple polygon has linear complexity and the problem of computing the inverse attraction region has a lower bound of $\Omega(n \log n)$ in monotone polygons and consequently in simple polygons.

Comthóth Lóegairi co Cretim ocus a Aided: Eagrán maille le hanailís liteartha agus teanga

Is scrúdú ar théacs amháin, Comthóth Lóegairi co Cretim ocus a Aided (CLcC), a chaomhnaítear i lámhscríbhinn amháin, Lebor na hUidre (LU), atá sa tráchtas seo. Bíodh is gurb é LU an lámhscríbhinn Ghaelach is sine a chaomhnaíonn scéalta leanúnacha i nGaeilge, agus gur ábhar staidéir ar leith i ngort na Gaeilge agus na Ceiltise é dá réir, níor scrúdaíodh CLcC as féin mar earra litríochta fós, ná ní dhearnadh mionscrúdú ar an teanga ann ach chomh beag. Ceapadh gur mhithid an téacs a mheas ar na cúiseanna sin. Roinntear an tráchtas ina dhá chuid, mar atá: (a) cuid a haon, a chuireann síos ar chomhthéacs na lámhscríbhinne agus ar cheisteanna a bhaineann lena lucht scríofa, chomh maith le hanailís liteartha ar théamaí a luaitear sa téacs féin. Déantar ceist an rangaithe a phlé chomh maith, is é sin, conas is ceart rangú a dhéanamh ar CLcC; (b) cuid a dó, is eagrán agus aistriúchán den téacs atá inti, chomh maith le nótaí teanga a scrúdaíonn gnéithe suntasacha den teanga, agus gluais. An dá shórt anailíse a chuirtear chun cinn i rith an tráchtais, .i. an scrúdú liteartha agus an t-iniúchadh ar an teanga, déantar iad a shuíomh i gcomhthéacs LU trí chéile oiread agus is féidir. Féachann an cur chuige seo le taispeáint gur de dhlúth na lámhscríbhinne féin na téamaí (mar shampla creideamh, cumhacht, ríogacht) is bun le CLcC, agus gur sampla an-spéisiúil de thoisí teanga LU an téacs seo, óir léiríonn sé caomhnú ábhar ón tSean-Ghaeilge chomh maith le forbairtí teanga a bhaineann le ré na Meán-Ghaeilge. Sna nótaí teanga, leis, cuirtear samplaí as lámhscríbhinní comhaimseartha eile san áireamh, chomh maith le foinsí níos sine ná sin, le bonn a chur faoin áitiú a dhéantar ar aois na teanga in CLcC.
