A influência do recebimento de recursos financeiros e a participação em eventos para a obtenção de resultados esportivos: o caso brasileiro / The influence of receiving financial resources and participation in events on obtaining sports results: the brazilian case

RESUMO O presente estudo teve por objetivo verificar a influência do recebimento de recursos financeiros por intermédio de políticas esportivas e da participação em eventos relevantes na obtenção de resultados esportivos em competições internacionais. A amostra deste estudo baseou-se em 907 atletas brasileiros que representaram o Brasil nas seguintes competições internacionais: Jogos Pan-Americanos de Lima 2019, Jogos Mundiais Militares (JMM) de Wuhan 2019 e Jogos Olímpicos de Verão de Tóquio 2020 (2021). Por meio da análise, pode-se observar que o fato de ser beneficiário de programas públicos esportivos e o fato de participar de competições internacionais influenciou na obtenção de resultados esportivos em competições internacionais. Pode-se perceber que receber recursos por meio de mais de um programa apresentou influência positiva, do que ser beneficiário de apenas um. Com base nestes achados, ficou exposto que o incentivo ao esporte por meio de bolsas, a participação em eventos esportivos e a quantidade de medalhas obtidas, tiveram correlação positiva com o financiamento concedido.

ABSTRACT The present study aimed to verify the influence of receiving financial resources through sports policies and participation in relevant events in obtaining sports results in international competitions. The sample of this study consisted of 907 Brazilian athletes who represented Brazil in the last international competitions: Pan American Games in Lima 2019, Military World Games (JMM) in Wuhan 2019 and Summer Olympic Games in Tokyo 2020 (2021). Through analysis, it can be observed that both the fact of being a beneficiary of public sports programs and the fact of participating in international competitions influenced the achievement of sports results in international competitions. Furthermore, it can be seen that receiving resources through more than one program had a positive influence, than being a beneficiary of just one. Based on these findings, it was shown that encouraging sports through scholarships, participation in sporting events and the number of medals obtained had a positive correlation with the funding granted.

Serial dependence in estimates of the monetary value of coins.

Perceptions of current stimuli are sometimes biased toward or away from past perceptions. This phenomenon is called serial dependence. However, it remains unclear whether serial dependence originates from lower-order perceptual processing, higher-order perceptual processing or cognitive processing. We examined the effects of serial dependence when participants estimated the total number of coins or the monetary value of coins displayed and found attractive effects in both tasks. The attractive effect observed in the value estimation task suggests that serial dependence occurs through higher-order cognitive processes during calculation. We also examined the effect of response history (i.e., the responses of participants on previous trials), with multiple regression analyses that simultaneously evaluated the effects of the previous stimuli and responses. In both number and value estimation tasks, the immediately prior response had an attractive effect on current responses, while the immediately prior stimuli exerted a repulsive effect. This pattern suggests that the attractive serial dependence found in the single regression analysis was due to the correlation between stimulus and response in the previous trials and that the effect of past stimuli per se may be an adaptation that increases sensitivity to current stimuli.

A Multi-Analytical Approach on Silver-Copper Coins of the Roman Empire to Elucidate the Economy of the 3rd Century A.D.

In this study, 160 silver-copper alloy denarii and antoniniani from the 3rd century A.D. were studied to obtain their overall chemical composition. The approach used for their characterisation is based on a combination of physical, chemical, and chemometric techniques. The aim is to identify and quantify major and trace elements in Roman silver-copper coins in order to assess changes in composition and to confirm the devaluation of the currency. After a first cataloguing step, µ-EDXRF and SEM-EDX techniques were performed to identify the elements on the coins' surface. A micro-destructive sampling method was employed on a representative sample of the coins to quantify the elements present in the bulk. The powder obtained from drilling 12 coins (keeping the two categories of coins separate) was dissolved in an acidic medium; heated and sonicated to facilitate dissolution; and then analysed by ICP-AES and ICP-MS. The two currencies had different average alloy percentages; in particular, the % difference of Ag was about 8%. The other elements were found in concentrations <1 wt%. Of these, the element highest in concentration were Pb and Sn, which is in agreement with the literature. The multivariate analysis performed on the data acquired revealed two groups of coins, corresponding to the two currencies.

Safe and effective management of esophageal coins in children with bougienage.

BACKGROUND: Coins are the foreign body most commonly ingested in infants and children. Coins retained in the esophagus require intervention to prevent complications. Management of retained esophageal coins remains variable both between and within institutions. We hypothesize that the incorporation of bougienage in the management of pediatric esophageal coins is safe and more cost-effective compared with traditional management strategies that use endoscopy. METHODS: We conducted a retrospective review of infants and children diagnosed with an esophageal foreign body managed at Children's Hospital of Wisconsin between January 2003 and June 2012. Pediatric otolaryngologists (ear-nose-throat, ie, ENTs) or pediatric surgeons manage all children with esophageal foreign bodies in a prospective call schedule that alternates weekly. RESULTS: During an 8.5-year period, 1,642 children were diagnosed with esophageal foreign bodies and 518 had a retained coin. For esophageal coins, ENT managed 218 cases and pediatric surgery managed 300. ENTs preferentially used endoscopy for coin removal, whereas pediatric surgeons used either endoscopy or esophageal bougienage for selected children meeting specific criteria. Bougienage was successful at advancing the coin into the stomach in 94% of patients, and endoscopy was successful at removing the coin from the esophagus in 100% of patients. The mean duration of stay was 0.6 days for endoscopy by ENT, 0.6 days for endoscopy by pediatric surgery, and 0.1 days for bougienage (P < .05). The median hospital charge was $4,593 for endoscopy by ENT, $5,379 for endoscopy by pediatric surgery, and $579 for bougienage (P < .05). There were 3 complications each in the endoscopy group for ENT and pediatric surgery. There were no complications in children undergoing bougienage. CONCLUSION: This is the first case series evaluating the management of children with esophageal coins using a prospective assignment to endoscopy versus endoscopy or bougienage. Our data support bougienage as a safe and cost-effective treatment for managing retained esophageal coins in selected children.

The cost of nickel allergy: a global investigation of coin composition and nickel and cobalt release.

BACKGROUND: Nickel is widely used in coins; nickel may cause contact allergy and allergic contact dermatitis in those who handle them. OBJECTIVES: To investigate alloy use, coin composition and nickel and cobalt release for a worldwide selection of currently circulating coins. MATERIALS AND METHODS: Eight hundred and fifty coins of 361 different denominations or issues from 52 countries were collected and analysed with X-ray fluorescence spectrometry and nickel and cobalt spot tests. RESULTS: Copper-nickel was the most frequently identified coin alloy, being observed in 100 denominations (28%), followed by aluminium-bronze (62, 17%). In total, 239 denominations released nickel (28%). Coins from Bolivia, Brazil and Costa Rica did not release nickel. Fewer than one-third of the denominations or issues from China, India, the euro area and Indonesia released nickel. In the United States, the Russian Federation, Japan, and Mexico, one-third or more of the denominations released nickel. CONCLUSIONS: This worldwide selection of circulating coins covered countries with 75% of the world population, and shows that the majority of the world population lives in countries where coins release nickel. Pertinently, ∼ 40% of circulating coin denominations do not release nickel.

[Generalization of money-handling though training in equivalence relationships]. / Generalización en el manejo del dinero mediante un entrenamiento en relaciones de equivalencia.

This research used a matching-to-sample procedure and equivalence learning process with language and verbal tasks. In the study, an application of the equivalence relationship of money was used with several kinds of euro coins presented. The sample consisted of 16 children (8 in the experimental group and 8 in the control group) aged 5 years. The prerequisite behaviors, the identification of coins and the practical use of different euro coins, were assessed in the pre and post phases for both groups. The children in the experimental group performed an equivalence task using the matching-to-sample procedure. This consisted of a stimulus sample and four matching stimuli, using a series of euro coins with equivalent value in each set. The children in the control group did not undergo this training process. The results showed a large variability in the children's data of the equivalence tests. The experimental group showed the greatest pre and post changes in the statistically significant data. They also showed a greater generalization in the identification of money and in the use of euro coins than the control group. The implications for educational training and the characteristics of the procedure used here for coin equivalence are discussed.

La historia de la medicina peruana través de las medallas conmemorativas / The Peruvian medical history through the commerative medals

La historia de la Medicina Peruana ha sido explorada desde diversas perspectivas; sin embargo, prácticamente no existen investigaciones que utilicen como fuente de información a las medallas conmemorativas, que por sí mismas pueden contener datos que no han sido registrados o escritos. Es gracias a la medallística, aquella rama de la numismática que estudia todo lo concerniente a las medallas, que podemos conocer hechos y circunstancias que se hubieran perdido irremediablemente. El objetivo de este artículo es valorar y considerar esta fuente, hasta hoy inédita en gran parte, como importante auxiliar en el estudio de nuestra historia médica.

The Peruvian history of medicine has been explored from different perspectives; however, practically do not exist studies that use the commemorative medals as a source of information, because themselves can contain unrecorded or unwritten data. Thanks to medalistics, the branch of numismatics that studies everything about the medals, we can know facts and circumstances that would have been irretrievably lost. The aim of this article is to evaluate and consider this source, largely unpublished until today, as an important aid in the study of our medical history.

Christmas: Years Like This. Ingested foreign bodies and societal wealth: three year observational study of swallowed coins.

OBJECTIVE: To examine the relation between coins ingested by children and the Dow Jones Industrial Average. DESIGN: Observational study. Main outcome measures Total value of coins ingested and number of incidents of coins versus other objects swallowed, measured before and after the stock market crash of October 2008. RESULTS: Eighteen objects, including 11 coins, were ingested (NASDAQ (numismatic and sundry detritus acquired) composite of 18). The total value of the 11 coins swallowed was $1.03 (FTSE 100 (fraction of the US$ or 100 cents) index of 103). The pecuniary extraction ratio (PE ratio) was 0.57 (9/16). Comparing values for a period before and after October 2008, the mean monthly NASDAQ composite (0.41 (SD 0.67) v 0.5 (0.85), P=0.75), FTSE 100 index in cents (2.3 (6.8) v 3.1 (7.8), P=0.77), and PE ratio (0.54 (0.52) v 0.66 (0.29), P=0.50) did not change. The mean end-of-month closing value of the Dow Jones, however, decreased significantly (12 537 (841.4) v 8388 (699.8), P<0.001) CONCLUSION: There was no detectable difference in the total value of coins ingested, or ratio of coins to other objects swallowed, before or after a massive stock market crash.

Safety and efficacy of a protocol using bougienage or endoscopy for the management of coins acutely lodged in the esophagus: a large case series.

STUDY OBJECTIVE: We report our experience using the bougienage procedure in the management of esophageal coins. METHODS: Observational case series of all patients presenting to our emergency departments with coins acutely lodged in the esophagus between 1994 and 2006. All patients were treated according to our protocol with either endoscopy or bougienage. Patients are eligible for bougienage if they have had a witnessed coin ingestion less than 24 hours before presentation and if esophageal coin position is confirmed by chest radiograph and there is no history of esophageal disease, surgery, or foreign body. Primary outcomes measured were complications, efficacy of procedure, hospital charges, length of stay, and return to the hospital. Length of stay and hospital charges data were gathered for patients presenting in the final 24 months of the study. RESULTS: Six hundred twenty patients were identified as having esophageal coins. Three hundred fifty-five patients had a successful bougienage, and 17 patients had unsuccessful bougienage. By comparison, 248 patients underwent endoscopy, and the coin was successfully removed in all but 1 of these patients. Of patients undergoing endoscopy, 89 were eligible for bougienage, but patient, parent, or physician preference was for endoscopic management. Eleven patients required reevaluation or readmission for complaints related to esophageal coin. The only complication was subglottic edema, causing respiratory distress in a single patient who had undergone endoscopy. Patients undergoing endoscopy had an average length of stay of 6.1 hours and average hospital charges were $6,087. Patients undergoing bougienage had an average length of stay of 2.2 hours and average hospital charges of $1,884. CONCLUSION: In properly screened patients with coins acutely lodged in the esophagus, bougienage offers a safe and effective alternative to other methods of coin management.

Dermal nickel exposure associated with coin handling and in various occupational settings: assessment using a newly developed finger immersion method.

BACKGROUND: The role of nickel in causing hand dermatitis in some occupations has been difficult to assess due to problems with reliable measurement of the exposure to nickel in the workplace and lack of a definitive threshold for nickel allergic contact dermatitis. It is not uncommon to find nickel allergy on patch testing but it is difficult to determine whether this is of relevance to occupational nickel exposure or simply a reflection of past exposure to nickel-plated jewellery or other nonoccupational nickel exposure. OBJECTIVES: To devise a simple and reproducible method to quantify the amount of nickel on the skin and to apply the technique to measure dermal nickel exposure in various occupational settings. METHODS: A rapid and simple sampling procedure was developed for determination of nickel on the skin of workers potentially exposed to nickel by exposing individuals to nickel-releasing coins and measuring exposure by immersing the exposed thumbs and index fingers directly into graduated sample tubes containing ultrapure water and aqueous nickel extracts. The solutions were analysed by inductively coupled plasma-optical emission spectrometry after stabilization with nitric acid. The method shows advantages over alternatives such as wipe testing and tape stripping in terms of extraction efficiency, speed and ease of operation in the field. A pilot survey of dermal nickel exposure for workers in several occupational settings was conducted. RESULTS: The study suggested that a 'normal' level of nickel on the skin is <10 ng cm(-2). Coin handling induced an appreciable increase in the amount of nickel on the skin within 2 min. Experiments indicated a linear relationship between coin handling (exposure time) and measured dermal nickel levels following standardized coin handling. A pilot survey, conducted among cashiers, shop assistants, bar staff, hairdressers and workers in the nickel industry revealed dermal nickel concentrations ranging from <0.9 to 7160 ng cm(-2). The levels of nickel on the skin of cashiers, shop assistants, bar staff and hairdressers were below the threshold level for water-soluble ionic nickel for occluded exposure at which 10% of nickel-allergic subjects react (0.01% or 100 parts per million, equivalent to 530 ng cm(-2)) and the five-times higher threshold for unoccluded exposure (500 parts per million). The levels in some nickel platers and nickel refinery workers approached or exceeded these levels. However, few cases of nickel dermatitis are observed in plating and refinery facilities, perhaps due to immune tolerance, self-selection or, for refinery workers, exposure to water-insoluble rather than water-soluble nickel compounds. The elicitation threshold for water-soluble nickel compounds cannot be compared directly with dermal exposure to water-insoluble nickel compounds as the latter release a significantly lesser amount of nickel ions. CONCLUSIONS: We describe a reproducible, simple and rapid procedure for the assessment of nickel levels in occupationally exposed individuals.

[Pharmacy tokens]. / Apotekspolletter.

This paper concerns a small group of ephemeral objects belonging to the Royal Coin Cabinet in Stockholm, namely tokens from the chemist shops in different Swedish towns. When the patient left his prescription at the chemist shop he got a token, made of metal or paper, in return. Later, when the patient came to collect his medicine he returned the token in exchange for the medicine. These tokens were mainly used during the 19th century.
