Eventos culturais para a recordação da marca: estudo do evento Tim Festival

Este estudo analisa o papel dos eventos culturais como um potente elemento socializador na estratégia da comunicação da marca com o mercado. os principais objetivos são retratar o uso da comunicação integrada de marketing como um diferencial sustentável, o marketing cultural frente às novas formas de comunicação com o mercado, a contextualização da marca e os eventos culturais como instrumento de branding. A metodologia desta pesquisa constitui-se em bibliografia, pesquisa documental, entrevistas e o estudo de caso da empresa Tim com o recorte Tim Festival edição 2005 em São Paulo. Dentre as conclusões encontradas, confirmou-se que a propaganda tradicional vem perdendo espaço para os eventos, mas ao mesmo tempo, por si só não se bastam, havendo a necessidade de atrelá-los a outras atividades promocionais. Verificou-se também que os eventos culturais comunicam a mensagem de forma envolvente e finalmente a consideração sobre a relação gratificante do evento com a lembrança de marca.(AU)

Géniuszok párharca. Milton Friedman és J. M. Keynes vitája Tim Congdon és Robert Skidelsky előadásában = War of the geniuses. The debate between Milton Friedman and J. M. Keynes as presented by Tim Congdon and Robert Skidelsky

Tavaly ünnepelte a közgazdász-társadalom Milton Friedman Nobel-díjas közgazdász születésének századik évfordulóját. A jubileumi megemlékezésnek különös aktualitást ad, hogy a 2008 óta tartó pénzügyi világválság hátterében ismét fellobbant a 20. századi közgazdaságtan két meghatározó irányzata - a Friedman nevével fémjelzett monetarizmus és a Keynes és követői által követett keynesizmus - közötti vita. E szerteágazó vitasorozat egyik "gyöngyszeme" két nemzetközileg ismert és elismert közgazdász, Tim Congdon és Robert (Lord) Skidelsky, összecsapása a Standpoint hasábjain 2009-ben. A szerző megmutatja, hogy a vita valójában nem a pénz fontosságáról vagy a mennyiségi pénzelmélet igazságáról folyt, hanem egyrészt egy sokkal elvontabb fogalomról: a bizonytalanság közgazdasági szerepéről, másrészt gyakorlati, gazdaságpolitikai kérdésekről: a monetáris és a fiskális politika lehetséges hatékonyságáról. A máig is tartó vitában "az inga többször kilengett", hol a keynesiánusok, hol a monetaristák javára, de még semmi nem dőlt el. ____ Last year economists marked the centenary of the birth of genius among them, Milton Friedman. The commemoration was especially topical because the world financial crisis that erupted in 2008 has brought sharply into focus again the old division in 20th-century economics between monetarism and Keynesianism. One highlight in this series of disputes was the 2009 clash between two internationally known and appreciated economists Tim Congdon and Robert (Lord) Skidelsky in the columns of Standpoint. The central element in the discussion is the role of money: what kind of economic policy to pursue, monetary or fiscal, to pull troubled economies out of crisis. The question closely resembles a decisive dilemma for Keynes in the 1930s. Though Keynes turned against some basic propositions of neoclassical economics, he never challenged the importance of money to the functioning of the economy, or the validity of the quantity theory of money. The author argues here that the issue is not about the formal category of money or demand for it, but about the far deeper economic concept of the role of uncertainty in economics. Another aspect concerns the relative efficiency of various kinds of economic policy, i. e. the strengths and weaknesses of monetary and fiscal policies.

Comparison of the Effects of Electrical Field Stimulation and Low-Level Laser Therapy on Bone Loss in Spinal Cord-Injured Rats

Objective: This study investigated the effects of low-level laser therapy (LLLT) and electrical stimulation (ES) on bone loss in spinal cord-injured rats. Materials and Methods: Thirty-seven male Wistar rats were divided into four groups: standard control group (CG); spinal cord-injured control (SC); spinal cord-injured treated with laser (SCL; GaAlAs, 830 nm, CW, 30mW/cm, 250 J/cm(2)); and spinal cord-injured treated with electrical field stimulation (SCE; 1.5 MHz, 1: 4 duty cycles, 30 mW, 20 min). Biomechanical, densitometric, and morphometric analyses were performed. Results: SC rats showed a significant decrease in bone mass, biomechanical properties, and morphometric parameters (versus CG). SCE rats showed significantly higher values of inner diameter and internal and external areas of tibia diaphyses; and the SCL group showed a trend toward the same result (versus SC). No increase was found in either mechanical or densitometric parameters. Conclusion: We conclude that the mentioned treatments were able to initiate a positive bone-tissue response, maybe through stimulation of osteoblasts, which was able to determine the observed morphometric modifications. However, the evoked tissue response could not determine either biomechanical or densitometric modifications.

Identification and Characterization of Ixodes scapularis Antigens That Elicit Tick Immunity Using Yeast Surface Display

Repeated exposure of rabbits and other animals to ticks results in acquired resistance or immunity to subsequent tick bites and is partially elicited by antibodies directed against tick antigens. In this study we demonstrate the utility of a yeast surface display approach to identify tick salivary antigens that react with tick-immune serum. We constructed an Ixodes scapularis nymphal salivary gland yeast surface display library and screened the library with nymph-immune rabbit sera and identified five salivary antigens. Four of these proteins, designated P8, P19, P23 and P32, had a predicted signal sequence. We generated recombinant (r) P8, P19 and P23 in a Drosophila expression system for functional and immunization studies. rP8 showed anti-complement activity and rP23 demonstrated anti-coagulant activity. Ixodes scapularis feeding was significantly impaired when nymphs were fed on rabbits immunized with a cocktail of rP8, rP19 and rP23, a hall mark of tick-immunity. These studies also suggest that these antigens may serve as potential vaccine candidates to thwart tick feeding.

An apparatus for in situ spectroscopy of radiation damage of polymers by bombardment with high-energy heavy ions

A new target station providing Fourier transform infrared (FT-IR) spectroscopy and residual gas analysis (RGA) for in situ observation of ion-induced changes in polymers has been installed at the GSI Helmholtz Centre for Heavy Ion Research. The installations as well as first in situ measurements at room temperature are presented here. A foil of polyimide Kapton HN (R) was irradiated with 1.1 GeV Au ions. During irradiation several in situ FT-IR spectra were recorded. Simultaneously outgassing degradation products were detected with the RGA. In the IR spectra nearly all bands decrease due to the degradation of the molecular structure. In the region from 3000 to 2700 cm(-1) vibration bands of saturated hydrocarbons not reported in literature so far became visible. The outgassing experiments show a mixture of C(2)H(4), CO, and N(2) as the main outgassing components of polyimide. The ability to combine both analytical methods and the opportunity to measure a whole fluence series within a single experiment show the efficiency of the new setup.

LOW-INTENSITY PULSED ULTRASOUND PRODUCED AN INCREASE OF OSTEOGENIC GENES EXPRESSION DURING THE PROCESS OF BONE HEALING IN RATS

The aim of this study was to measure the temporal expression of osteogenic genes during the process of bone healing in low-intensity pulsed ultrasound (LIPUS) treated bone defects by means of histopathologic and real-time polymerase chain reaction (PCR) analysis. Animals were randomly distributed into two groups (n = 30): control group (bone defect without treatment) and LIPUS treated (bone defect treated with LIPUS). On days 7, 13 and 25 postinjury, 10 rats per group were sacrificed. Rats were treated with a 30 mW/cm(2) LIPUS. The results pointed out intense new bone formation surrounded by highly vascularized connective tissue presenting a slight osteogenic activity, with primary bone deposition was observed in the group exposed to LIPUS in the intermediary (13 days) and late stages of repair (25 days) in the treated animals. In addition, quantitative real-time polymerase chain reaction (RT-qPCR) showed an upregulation of bone morphogenetic protein 4 (BMP4), osteocalcin and Runx2 genes 7 days after the surgery. In the intermediary period, there was no increase in the expression. The expression of alkaline phosphatase, BMP4 and Runx2 was significantly increased at the last period. Our results indicate that LIPUS therapy improves bone repair in rats and upregulated osteogenic genes, mainly at the late stages of recovery.
