Psychophysical estimation of acid intensity and determination of sweet-acid interaction in a fish paste containing glycerol

In a fish paste made with cooked Brazilian flathead (Percophis brasiliensis), glycerol (17%), sodium chloride (1.5%) and potassium sorbate (0.1%) the following acid percentages: 0.2; 0.4; 0.6; 0.8, 1 and 1.5% w/w were incorporated to determine the relationship between added acetic acid and the sensorially perceived intensity, and the effects of the combination of sweet-acid tastes. Tests for paired comparison, ranking and structured verbal scales for sweet and acid attributes and psychophysical test were carried out. There was a perceptible difference among samples for differences of 0.4 units of acid concentration. Samples indicated as sweeter by 89.47% of the judges were those containing a lesser acid concentration. A reduction in glycerol sweetness when increasing acid levels was observed. Acetic acid reduced the sweetness of glycerol and inversely glycerol reduced the acidity of acetic acid. The data obtained with the magnitude estimation test agree with Steven's law.

Incentivising Innovation? The competition law approach to the new challenge clauses in the competition rules for technology licensing agreements of the EU

Tutkielman aiheena on EU:n kilpailuoikeudellinen lähestymistapa challenge-lausekkeisiin teknologinsiirtosopimuksia koskevassa ryhmäpoikkeusasetuksessa. Teknologian lisensoinnin katsotaan olevan tärkeä väline teknologian kehityksen levittämisessä ja innovaation edistämisessä. Joissakin tapauksissa lisenssisopimus voi sisältää kilpailua rajoittavia lausekkeita, joiden voidaan kuitenkin nähdä hyödyttävän kilpailua kokonaisuutta arvostellen. Tällaisia lausekkeita ovat niin sanotut ”no-challenge” – lauseke, eli sopimusehto, jonka nojalla lisenssinsaaja sitoutuu olemaan haastamatta lisensoidun immateriaalioikeuden pätevyyttä ja ”termination-on-challenge” – lauseke, joka antaa lisensoijalle haastettaessa oikeuden päättää lisenssisopimus. Tutkielmassa perehdytään challenge -lausekkeiden hyväksyttävyyden arviointiin Euroopan unionin kilpailuoikeuden näkökulmasta uuden 1.5.2014 voimaan tulleen ryhmäpoikkeusasetuksen valossa. Muissa kuin yksinoikeuksia luovissa teknologiansiirtosopimuksissa olevat termination-on-challenge – lausekkeita tulee uusimmassa ryhmäpoikkeusetuksessa aina perustua yritysten itse suorittamaan tapauskohtaiseen arviointiin. No-challenge – lausekkeet ovat jatkossakin aiemman käytännön mukaisesti ryhmäpoikkeuksen soveltamisalan ulkopuolella. Komission on perustellut challenge - lausekkeiden jättämistä asetuksen ulkopuolelle julkisella intressillä, joka on päästä eroon mitättömistä immateriaalioikeuksista. Komission on katsonut, että challenge – lausekkeiden kilpailua rajoittava ominaisuus on mitättömien immateriaalioikeuksien esiintyminen markkinoilla, mikä osaltaan vääristää kilpailua ja hidastaa toimijoiden markkinoille pääsyä. Toisaalta lausekkeiden voidaan sanoa edistävän kilpailua, sillä ne usein tarjoavat immateriaalioikeuden haltijalle riittävän oikeussuojan ja kannustimen lisensoida teknologia, mikä lisää kilpailua, keksijöiden kannustimia panostaa innovaatioihin sekä vähentää transaktiokustannuksia. Tutkielman keskeinen tulos on ennen kaikkea challenge-lausekkeiden kilpailuvaikutusten tunnistamisessa ja komission perusteluiden kriittisessä arvioinnissa. Komission linjauksen perustelut eivät saa riittävää tukea ottaen huomioon vaikutustenarvioinnin, EU:n tuomioistuinkäytännön sekä taloustieteellisen lähestymistavan. Tutkielman tulosten pohjalta ja tukeutuen eri oikeuslähteisiin, taloustieteellisiin argumentteihin ja oikeusvertailevaan tutkimukseen, on mahdollista tehdä johtopäätöksiä niistä seikoista ja argumenteista, joilla on merkitystä uuden politiikkalinjauksen kilpailuvaikutuksiin.

Direct effects of soybean seed vigor on weed competition

Seed vigor is one of the factors that determines the speed and uniformity of seedling emergence and initial plant growth, which are crucial aspects in the competition against weeds. The objective of this study was to verify the direct effects of soybean seed vigor on weed competition and grain yield. A field experiment was conducted with three seed lots of the "Conquista" cultivar, previously characterized by physiological tests as having high, intermediate and low vigor. The experiment was divided into weeded and unweeded plots with six treatments. Crop plant height, weed dry mass accumulation and crop grain yield data were recorded. Seed vigor did not affect plant height and grain yield. Plants which developed from seeds with high and intermediate vigor showed the best results for competition against weeds, reducing weed dry mass accumulation. Plants which developed from high vigor seeds give the best results for grain yield for both weeded and unweeded treatments.

Innovation, competition and financial vulnerability in economic development

The financial sector has been viewed traditionally as either providing the "oil" for the "wheels of commerce" or as a parasite on the real sector of the economy where real productivity gains provide for increasing real wages and per capita incomes. The present paper takes a different route and attempts to an analysis of financial institutions on a par with the production sector of the economy. It also develops a link which amalgamates "the knowledge-based" perspective on firms' operations with Schumpeterian financial leverage to exploit productivity enhancing innovations, and Minsky's tendency towards financial fragility. The analysis also leads to some policy recommendations concerning financial regulation, risk management and financial institution's building.

Inter-jurisdictional fiscal competition: a review of the literature and policy recommendations

This paper surveys the literature on fiscal competition. We consider tax and expenditure competition in a more general set up where different jurisdictions within a federation may compete in the provision of public goods in order to attract some residents (Tiebout, 1956) and expel others (Brueckner, 1999); and/or for business. We address the vast literature on welfare gains or losses of these types of competition. Then, we discuss the empirical evidence, focusing on estimates of the sensitiveness of production factors to tax differentials and on the importance of the strategic interdependence among jurisdictions. We combine econometric studies with some case studies. Last we discuss the design of mechanisms to cope with fiscal competition, especially under a more global environment where factors become more mobile.

Os limites da participação dos trabalhadores nos ganhos das empresas

This article argues that workers’ share in profits are actually a share in extra surplus value obtained by means of more intensified labor. Cost reductions obtained by means of more intensified lean production methods cause wages to represent a smaller fraction of the product of a working day when measured at market value. The increased market rate of surplus value is the basis for workers’ shares in profits. However, as competition continuously levels out such advantages, the share in profits becomes dependent on a continuous strive to reducing costs and intensifying labor.

Parental and Successor Liability in EU Competition Law Infringements

Under EU competition law, parent companies may be held jointly and severally liable for the competition law infringements committed by their subsidiaries. The possibility of holding parent companies liable demonstrates a significant exception from the idea of separate legal entities. However, it is not the only deviation developed under EU competition law. In cases, where the legal entity responsible for the anti-competitive conduct has changed its form, liability can be attributed to the new operator, in particular, to its successor. The principles of legal certainty and legitimate expectations are issues that surround the doctrines of parental and successor liability. The aim of this thesis is to present a comprehensive comparative analysis of the parental and successor liability doctrines and to clarify the conditions under which it is possible to attribute liability for the infringements of EU competition law. The main purpose is therefore to demonstrate the problems related to the allocation of liability and to discuss whether these liability principles, established to assure the effective enforcement of the EU competition rules, are good solutions. The research methods used in this thesis are the legal dogmatic approach and the comparative law approach. The former enables the possibility of using the case law and legislation as a framework in which the difficulties concerning the application of parental and successor liability can be discussed while the latter ensures the comparison of the characteristics and judgments. The doctrines of parental and successor liability are both well established, but the application practice has caused several difficulties. These problems derive from, inter alia, the broadness and disjointed developed of the doctrines. There has been much recent case law dealing with these issues and having the potential to open up a considerable risk and to allocate strict liability for parent and successor companies.

Reproduction in the temperate crayfish, Orconectes rusticus: intermale aggression, copulatary behaviour, and sperm competition

The chelipeds of Orconectes rusticus are sexually dimorphic; males possessing the larger. Males use their chelae in intermale aggressive interactions, both to threaten, and assault opponents. In dyadic interactions males with larger chelae were dominant over otherwise physically similar opponents. A high frequency of attack behaviour, coupled with a low frequency of threats during these interactions indicates that actual physical contact is required for opponent assessment. Large clawed males oriented females into the copulatory position faster than small clawed males. Females more frequently escaped the precopulatory-grasp attempts of small clawed males. Additionally, male-female pairs that included a large clawed male remained in copula longer than pairs that included a small clawed male. Sperm of the second male to mate took precedence over the sperm of the primary male. Sperm precedence was incomplete; about 900/0 paternity accrued to the second male.

Subjective, behavioural and electrophysiological measurements of the time-course and intensity of sleep inertia after a full night of sleep /

Several recent studies have described the period of impaired alertness and performance known as sleep inertia that occurs upon awakening from a full night of sleep. They report that sleep inertia dissipates in a saturating exponential manner, the exact time course being task dependent, but generally persisting for one to two hours. A number of factors, including sleep architecture, sleep depth and circadian variables are also thought to affect the duration and intensity. The present study sought to replicate their findings for subjective alertness and reaction time and also to examine electrophysiological changes through the use of event-related potentials (ERPs). Secondly, several sleep parameters were examined for potential effects on the initial intensity of sleep inertia. Ten participants spent two consecutive nights and subsequent mornings in the sleep lab. Sleep architecture was recorded for a fiiU nocturnal episode of sleep based on participants' habitual sleep patterns. Subjective alertness and performance was measured for a 90-minute period after awakening. Alertness was measured every five minutes using the Stanford Sleepiness Scale (SSS) and a visual analogue scale (VAS) of sleepiness. An auditory tone also served as the target stimulus for an oddball task designed to examine the NlOO and P300 components ofthe ERP waveform. The five-minute oddball task was presented at 15-minute intervals over the initial 90-minutes after awakening to obtain six measures of average RT and amplitude and latency for NlOO and P300. Standard polysomnographic recording were used to obtain digital EEG and describe the night of sleep. Power spectral analyses (FFT) were used to calculate slow wave activity (SWA) as a measure of sleep depth for the whole night, 90-minutes before awakening and five minutes before awakening.

Social neuroendocrinology of competition

The relationship between testosterone concentrations and aggressive behaviour in studies of people has produced very inconsistent findings. However, one consistent fmding that has emerged is that competitive and aggressive interactions potentiate testosterone release in both human and non-human species. It has been argued that socially-induced alterations in testosterone concentrations may function to influence ongoing and/or future social behaviour. Nonetheless, few studies have empirically tested this hypothesis. The current series of experiments was designed to address the extent to which competitioninduced fluctuations in testosterone concentrations were associated with ongoing and/or subsequent social behaviour. In Study 1, men (n = 38) provided saliva samples prior to, and at the conclusion of, the Point Subtraction Aggression Paradigm (PSAP). Although baseline testosterone concentrations were not related to aggressive behaviour, there was a positive correlation between change in testosterone and aggressive behaviour such that men who were most aggressive on the PSAP demonstrated the largest increase in testosterone concentrations. Furthermore, a rise in testosterone during the PSAP predicted willingness to choose a subsequent competitive task. In Study 2, men and women provided saliva samples prior to and after competing against a same-sex opponent on the Number Tracing Task (NTT). The outcome of the competition was rigged such that half of the individuals won most of the races, while the other half lost most of the races, thus experimentally creating a winner and loser in the laboratory. Following the competitive interaction, men and women played the PSAP with their same-sex partner. Results indicated that men selected the aggressive response (but not reward or protection responses), more frequently than women. For men assigned to the loss condition, an increase in testosterone concentrations in response to the NTT predicted subsequent aggressive behaviour. For men assigned to the win condition, an increase in testosterone concentrations in response to the NTT predicted subsequent aggressive behaviour, but only among those men who scored high on trait dominance. Change in testosterone and trait dominance did not predict aggressive behaviour in women. In Study 3, men provided saliva samples prior to, during, and at the end of the PSAP. They were randomly assigned to one of four experimental conditions that differed in the extent to which they were provoked and whether they received reward for behaving aggressively (i.e., stealing points). Results indicated that baseline testosterone concentrations did not correlate with aggression in any of the experimental conditions. Consistent with Study 1, there was a positive correlation between change in testosterone and aggressive behaviour among men who were provoked, but did not receive reward for aggression (i.e., reactive condition). Men who were provoked but did not receive reward for aggression enjoyed the task the most and were more likely to choose the competitive versus non-competitive task relative to men assigned to the other experimental conditions. Also, individual differences in aggressive behaviour among these men were positively correlated with the extent to which they enjoyed the task. Together, these studies indicate that testosterone dynamics within the context of competition influence subsequent competitive and aggressive behaviours in humans and that testosterone may be a marker of the intrinsically rewarding nature of costly aggressive behaviour.

Keyword Competition and Determinants of Ad Position in Sponsored Search Advertising

Given the significant growth of the Internet in recent years, marketers have been striving for new techniques and strategies to prosper in the online world. Statistically, search engines have been the most dominant channels of Internet marketing in recent years. However, the mechanics of advertising in such a market place has created a challenging environment for marketers to position their ads among their competitors. This study uses a unique cross-sectional dataset of the top 500 Internet retailers in North America and hierarchical multiple regression analysis to empirically investigate the effect of keyword competition on the relationship between ad position and its determinants in the sponsored search market. To this end, the study utilizes the literature in consumer search behavior, keyword auction mechanism design, and search advertising performance as the theoretical foundation. This study is the first of its kind to examine the sponsored search market characteristics in a cross-sectional setting where the level of keyword competition is explicitly captured in terms of the number of Internet retailers competing for similar keywords. Internet retailing provides an appropriate setting for this study given the high-stake battle for market share and intense competition for keywords in the sponsored search market place. The findings of this study indicate that bid values and ad relevancy metrics as well as their interaction affect the position of ads on the search engine result pages (SERPs). These results confirm some of the findings from previous studies that examined sponsored search advertising performance at a keyword level. Furthermore, the study finds that the position of ads for web-only retailers is dependent on bid values and ad relevancy metrics, whereas, multi-channel retailers are more reliant on their bid values. This difference between web-only and multi-channel retailers is also observed in the moderating effect of keyword competition on the relationships between ad position and its key determinants. Specifically, this study finds that keyword competition has significant moderating effects only for multi-channel retailers.

Interaction between stress and immunity during a week leading to competition in young athletes

This study examined changes in the salivary concentrations of immunoglobulin A (sIgA), cortisol (sC), testosterone (sT) and testosterone-to-cortisol ratio (T/C) in 23 competitive swimmers, 11-15 years old, during a week leading to competition as compared to a control (non-competitive) week. Results showed no effect of week or day, and no significant week-by-day interaction for sIgA, sC and T/C. In contrast, sT significantly decreased during the week of competition, along with a 7%, non-significant decrease in the weekly T/C. The latter suggests that the swimmers were in a catabolic state due to their training, but this did not have a negative effect on their performance Since sC did not change over the two weeks and according to the sport anxiety scale, competition stress was relatively low in these peri-pubertal athletes, it is concluded that in the absence of high cortisol levels mucosal immunity is unaffected in young athletes prior to competition.
