Rejection of an inequitable and yet unintended outcome in a truncated ultimatum game was examined in an experiment with 46 undergraduate students (27 men and 19 women) from a large national university in Japan. In an ultimatum game, one of two players, the proposer, makes an offer to divide a fixed-sum of money. The other player, the responder, decides whether to accept or reject the offer. When the responder rejects the proposer's offer, neither of the two players receives a reward. Previous work examining the behavior of participants in the truncated ultimatum game employed strategy method in their experimental design. We examined whether these previous findings would be replicated in an experimental design that did not use the strategy method and instead used the standard one-shot game. Seven out of 46 responders given an inequitable offer rejected it, replicating prior results with the strategy method. We further found that subjects who rejected an offer that was involuntary and yet inequitable did not over-attribute intentions to the proposer's involuntary behavior more strongly than did acceptors. These findings strongly suggest that aversion to inequity is the explanation for the subjects' rejection of the inequitable offer.

Forty-seven participants attended an experiment to rate two infants according to their perceived behavior. Half of participants rated in a setting where one infant identified with prematurely born (PL) and the other with full-term birth (FTL). The rest rated with the same configuration, except those labels were swapped for the infants. Results showed not significant difference between PL and FTL for perceived strength, alertness, and physical size. But participants rated FTL infants more positively for motor coordination. Moreover, statistical interaction between two infants when they are presented simultaneously was found and further studies seem necessary to investigate interactions more. A new experimental design to study attitudes via ultimatum game is proposed. In general, previous findings of prematurity stereotyping is replicated partially, but it does not count as an evidence for the rejection of the prematurity stereotyping hypotheses.

The combine harvest for soybean crops market are currently available two types of combine with header or platform, one of conventional with revolving reel with metal or plastic teeth to cause the cut crop to fall into the auger header and the other called "draper" headers that use a fabric or rubber apron instead of a cross auger, there are few test about performance of this combine header for soybean in Mato Grosso State. The aim of this work was to evaluate the soybean harvesting quantitative losses and performance using two types combine header in four travel speed. The experiment was conducted during soybean crops season 2014/15, the farm Tamboril in the municipality of Pontes e Lacerda, State of Mato Grosso. The was used the experimental design of randomized blocks, evaluating four forward harvesting speeds (4 km h-1, 5 km h-1, 6 km h-1 and 7 km h-1), the natural crops losses were analyzed, loss caused by the combine harvester (combine header, internal mechanisms and total losses) and was also estimated the  field performance of each combine. Data were submitted to analysis of variance by F test and compared of the average by Tukey test at 5% probability. The results show the draper header presents a smaller amount of total loss and in most crop yield when compared with the conventional cross auger.

Bicultural identity orientations have rarely been examined in relation to both perceived discrimination and psychological distress. Furthermore, these constructs have usually been studied in isolation, but their intersection is essential for understanding intercultural relations in multicultural societies. Using cross-sectional data from 1,143 Canadian undergraduate students from immigrant families, this study explored the relationship between perceived discrimination and psychological distress, and how bicultural identity orientations might mediate this relationship. The structural equation modeling results indicated that perceived discrimination was associated with higher levels of psychological distress and hybrid, monocultural, alternating, and conflicted orientations, but lower levels of complementary orientation. Alternating and conflicted orientations were related to higher psychological distress, whereas the other orientations were not. Alternating and conflicted orientations mediated the relationship between perceived discrimination and psychological distress, whereas the other orientations did not. The findings are discussed in light of theories on identity integration, rejection–identification, and acculturation.

The influences of task type on search of the World Wide Web using search engines without limitation of search domain were investigated. 9 graduate and undergraduate students studying psychology (1 woman and 8 men, M age = 25.0 yr., SD = 2.1) participated. Their performance to manipulate the search engines on a closed task with only one answer were compared with their performance on an open task with several possible answers. Analysis showed that the number of actions was larger for the closed task ( M = 91) than for the open task ( M = 46.1). Behaviors such as selection of keywords (averages were 7.9% of all actions for the closed task and 16.7% for the open task) and pressing of the browser's back button (averages were 40.3% of all actions for the closed task and 29.6% for the open task) were also different. On the other hand, behaviors such as selection of hyperlinks, pressing of the home button, and number of browsed pages were similar for both tasks. Search behaviors were influenced by task type when the students searched for information without limitation placed on the information sources.

Introduction: The Moyers’ probability tables are used in mixed dentition analysis to estimate the extent of space required for the alignment of canines and premolars, by correlating the mesiodistal size of lower incisors with the size of permanent canines and premolars. Objective: This study intended to evaluate the applicability of the Moyer's probability tables for predicting the mesiodistal space needed for the correct location of premolars and permanent canines non-erupted, in adolescents of the city of Cordoba, Argentina, who show different facial biotypes. Materials and Methods: Models and tele-radiographies of 478 adolescents of both genders from 10 to 15 years of age were analyzed. The tele-radiographies were measured manually in order to determine the facial biotype. The models were scanned with a gauged scanner (HP 3670) and measured by using Image Pro Plus 4.5 software. Results: According to this study, the comparison between the Moyer´s probability table, and the table created at the National University of Córdoba (UNC) (at 95%, 75%, and 50%) shows that, in both tables, a higher value of mesiodistal width of lower incisors corresponds to a bigger difference in the space needed for permanent canines and premolars; being the need for space for permanents canines and premolars bigger in the UNC´s table. On the other hand, when contrasting the values of mesiodistal space for permanent canines and premolars associated with each facial biotype, the discrepancies between groups were not statistically significant (P >0.05). However, we found differences in the size of the space required according to the mesiodistal width range of the lower incisors for each biotype: a) The comparison of lower-range values, with a mesialdistal width of lower incisors less than 22 mm, the space required for permanent canines and premolars resulted smaller in patients with dolichofacial biotype than in patients with mesofacial and braquifacial biotypes. The latter biotypes have meager differences between them. b) The comparison of mid-range values, with a mesialdistal width of lower incisors from 22 to 25 millimeters, shows that the values of required alignment space are similar in the three facial biotypes. c) Finally, the comparison of upper range values, with a mesialdistal width of lower incisors greater than 25 millimeters, indicates that the space required for dolichofacial biotypes tends to be higher than in mesofacial and brachyfacial biotypes. Conclusion: The Moyer´s probability tables should be created to meet the needs of the population under study, with no consideration of patients’ facial biotypes.

In this article of the Doctor of Philosophy, professor of Taras Shevchenko Kyiv National University, Chuiko Vadim Leonidovich and Atamanchuk-Angel Valerii Ivanovich is applied the principle of «first philosophy» as the foundation of the a priori prerequisites of possible cognition, which define an existence in general rather than its individual parts. This application of metaphysics made it possible to introduce methods of «universal algebra» for the implementation of humanitarian research using algebraic description with the help of three notion: plural, operations, relation. This methodological novation makes it possible to create demonstrative models of social systems, not their constructions, because constructionsare traditionally makeby using binary description that use only two notions, categories. Question: How to fill the notion of «public agreement» with the actual content? How to make all generations participate in the adoption of a social contract? How to create a new one, without destroying it entirely, maintaining stability? How to ensure a high degree of mutation — rebuilding, rebuilding and construction? Introduced in the algebraic sense, the notion of «trust» as a definition of what is necessary for the existence of a society of being as such, forms an algebra that models social relations by the operation of trust, not violence. Based on the above, we can talk about creating a mathematical politics. Matpoliticsdeal with ideal political objects. Matpolitics is the activity of a summation of algebras. These algebras differ from each other by the choice of operations. Plurals that consist of different algebras can be the carrier of the algebra. In this case, we are talking about the algebra of trust / credo, whose signature consists of the following operations: sovereignty, trust / credit, understanding of need for the Other, agreement and recursive procedures. The result of the implementation of these methodological guidelines are the answers to the following questions: How to make the concept of «social agreement» really meaningful? How can all generations (and the unborn, too) be involved in the social agreement? How to create a new one, without destroying the foundations of the existing one, to realize the idea of conservative development: restructuring and building a new one? Based on the provisions of the algebra of trust, society appears as a plurality of sovereigns — C, possessing the full range of rights to identify trust / distrust — Di, creating agreements — Yn, and for their completeness they have and understand the need for the other — Ik. The model presented is a system of treaties that are not an abstract concept of the state, but an agreement with specific elected people who have gained the trust of those to whom they temporarily render their services. Agreements are urgent, limited by time frame, with obligatory full responsibility of the parties.

Expressing an authoritative voice is an essential part of academic writing at university. However, the performance of the authorial self in writing is complex yet fundamental to academic success as a large part of academic assessment involves writing to the academy. More specifically, the performance of the authorial self can be complex for English as a Second Language (ESL) student-writers. This research investigated the extent to which ESL first-year students at the Fiji National University perform their authorial voice using interactional metadiscourse in their academic writing. The study employed a quantitative analysis of corpus produced by 16 Fijian ESL undergraduate students enrolled in an EAP course. The research found that the ESL authorial voice was predominantly expressed through boosters and attitude markers, with relatively little usage of other interactional metadiscoursal elements such as hedges, engagement markers and self-mentions. Further, the research showed that this particular cohort expressed their authorial voice and identity through boosted arguments and avoiding language that directly mentions the authorial self. The study concludes that the ESL authorial self for this cohort manifests itself in a selected range of selected interactional metadiscoursal elements, requiring the need to raise the awareness of self-reflective expressions for ESL students. The study also encourages further exploration of ESL authorial identity construction in academic writing at undergraduate level and beyond.

Field experiment was conducted at National Horticultural Research Institute (NIHORT), Mbato Sub-station, Okigwe, Imo State, South-eastern Nigeria in the 2012 and 2013 cropping seasons to establish the most appropriate time to introduce component crops in cocoyam/cowpea mixture. Five different planting schemes (two and four weeks before, two and four weeks after and same day) and two cowpea genotypes (climbing Akidienu and erect IT97K-499-35) were used. The component crops were grown in monocultures to assess the productivity of the systems. The experimental design used was a completely randomized design with three replicates. Growth and yield of cocoyam and the cowpea genotypes increased significantly (P<0.05) when either of the component crops was planted earlier than the other. Intercropping reduced significantly (P<0.05) cocoyam yield by 0.7 − 74% in IT97K-499-35 and 22 − 80% in Akidienu. Sowing the cowpea genotypes the same day or before cocoyam resulted in over-yielding of cowpea, whereas sowing Akidienu and IT97K-499-35 after cocoyam caused pod yield reductions of 64% − 73% and 32% − 59% on average, respectively. Cocoyam planted two weeks before IT97K-499-35 produced more satisfactory yields of the intercrops than the other planting schedules with LER, LEC and ATER of 2.15, 1.03 and 1.57, respectively.

Although there is no standardization of the notion of competence and for the instruments used in its evaluation, generic competences are associated with employability, and understood as a composition of cognitive and practical abilities, behavioral and social skills, gathering individual characteristics and qualities required for activities of different professions. Education promotes the development of specific competences for the exercise of certain occupations, in addition to opportunities for increasing generic competences, which are also required in the labor market. This study targets to evaluate self-perception of the valuation of generic competences acquired in undergraduate students from nocturnal courses of Brazilian private university, according to area of knowledge and condition of being or not inserted in the labor market. 1,001 of these students were evaluated in the third year of their graduation, using the Generic Competences Scale. The highest value in the global sample was attributed to Responsibility at work, followed by Ethical commitment and, thirdly, by Capacity to learn. At the other end, of lesser value, were Capacity for organization and planning, Ability to manage information and Problem solving. These results were compared with data from other studies, in Latin America and Europe.
