RESUMO

Academic dishonesty is prevalent and has unfortunately become normalized in post-secondary institutions worldwide. The COVID-19 pandemic more than two years ago led to an increase in cheating and confrontation of instructors with academic honesty. The main objective of this study was to create an explicative model according to the levels of morality, pragmatism, and gender. Researchers applied an online questionnaire to 735 anonymous university students. Analysis showed that participants were less honest in morality than in pragmatism, but the average value was very close for both dimensions. A substantial number of students with low and moderate levels of dishonesty were observed in both moral and pragmatic contexts. The initial hypothesis was partially validated, as the level of morality was associated with the level of pragmatism rather than gender, indicating a direct albeit moderate impact of pragmatism on morality. We confirmed the second hypothesis, showing the influence of gender and morality on the level of pragmatism. Participants suggested that English as a Foreign Language instructors should modify their approach, account for ethical considerations, offer extra classes, revise teaching and evaluation methods, and sanction students who cheat. Surprisingly, results show a slight tendency for lower honesty in morality compared to pragmatism. Despite honest behaviors, it is essential to address gender differences and promote academic honesty through education, policies, and a culture of honesty.

RESUMO

Important bacterial pathogens such as Pseudomonas aeruginosa produce several exoproducts such as siderophores, degradative enzymes, biosurfactants, and exopolysaccharides that are used extracellularly, benefiting all members of the population, hence being public goods. Since the production of public goods is a cooperative trait, it is in principle susceptible to cheating by individuals in the population who do not invest in their production, but use their benefits, hence increasing their fitness at the expense of the cooperators' fitness. Among the most studied virulence factors susceptible to cheating are siderophores and exoproteases, with several studies in vitro and some in animal infection models. In addition to these two well-known examples, cheating with other virulence factors such as exopolysaccharides, biosurfactants, eDNA production, secretion systems, and biofilm formation has also been studied. In this review, we discuss the evidence of the susceptibility of each of those virulence factors to cheating, as well as the mechanisms that counteract this behavior and the possible consequences for bacterial virulence.

RESUMO

Cheating forms part of a complex emotional and cognitive process. However, although a relatively mundane phenomenon, instruments to evaluate cheating and its effects socially are scarce. This paper presents a five-stage approach aimed at providing validity to an instrument designed to assess cheating - specifically, its detection, and emotional reactions towards it once detected. An instrument was designed after (1) reviewing the relevant literature on cheating, in order to (2) design a bank of stimuli, (3) formulate a Delphi panel to judge the most coherent and pertinent ones, and (4) perform three pilot studies to adjust the final version of the instrument. Results from Stages 1 to 4 show that content validity was achieved for the Instrument for Detecting Cheating and its Emotional Reactions (INDETRAE, in Spanish: Instrumento para la Detección de Trampa y sus Reacciones Emocionales). Stimuli were grouped into five categories of 18 different scenarios, for a total of 90 vignettes: meaning, the INDETRAE is a 5-category, vignette-based questionnaire consisting of contrasting social cost-benefit scenarios, where the cheating situation affects an undefined, a first or a third person, and also a neutral category with no cheating. In Stage 5, several chi-squared tests (p < 0.0005) revealed significant differences between categories, proving that the instrument can indeed be used to detect cheating and to identify differentiated emotional reactions - for example, anger when there was detriment to a third person as opposed to neutral situations, or glad when there was a case of cheating which benefited the first person. The last stage counts as the first approximation to support construct validity of the INDETRAE. The most important contribution of this work consists in developing an instrument to detect cheating, confirmed by the resulting emotional reactions, which therefore demonstrate its validity.

RESUMO

Cooperation in microbial communities via production of public goods is susceptible to social cheating, since selfish individuals that do not contribute to their synthesis but benefit from their production thrive in the presence of cooperators. This behavior has been observed in the laboratory using bacterial and yeast models. Moreover, growing evidence indicates that cheating is frequent in natural microbial communities. In the laboratory, social cheating can promote population collapse or "tragedy of the commons" when excessive. Nevertheless, there are diverse mechanisms that counteract cheating in microbes, as well as theoretical and experimental evidence that suggests possible beneficial roles of social cheaters for the microbial populations. In this mini review manuscript we compile and discuss such possible roles.

RESUMO

Pseudomonas aeruginosa is one of the main models to study social behaviors in bacteria since it synthesizes several exoproducts, including exoproteases and siderophores and release them to the environment. Exoproteases and siderophores are public goods that can be utilized by the individuals that produce them but also by non-producers, that are considered social cheaters. Molecularly exoprotease cheaters are mutants in regulatory genes such as lasR, and are commonly isolated from chronic infections and selected in the laboratory upon serial cultivation in media with protein as a sole carbon source. Despite that the production of exoproteases is exploitable, cooperators have also ways to restrict the growth and selection of social cheaters, for instance by producing toxic metabolites like pyocyanin. In this work, using bacterial competitions, serial cultivation and growth assays, we demonstrated that rhamnolipids which production is regulated by quorum sensing, selectively affect the growth of lasR mutants and are able to restrict social cheating, hence contributing to the maintenance of cooperation in Pseudomonas aeruginosa populations.

RESUMO

Quorum sensing in Pseudomonas aeruginosa controls the production of costly public goods such as exoproteases. This cooperative behavior is susceptible to social cheating by mutants that do not invest in the exoprotease production but assimilate the amino acids and peptides derived by the hydrolysis of proteins in the extracellular media. In sequential cultures with protein as the sole carbon source, these social cheaters are readily selected and often reach equilibrium with the exoprotease producers. Nevertheless, an excess of cheaters causes the collapse of population growth. In this work, using the reference strain PA14 and a clinical isolate from a burn patient, we demonstrate that the initial amount of public goods (exoprotease) that comes with the inoculum in each sequential culture is essential for maintaining population growth and that eliminating the exoprotease in the inoculum leads to rapid population collapse. Therefore, our results suggest that sequential washes should be combined with public good inhibitors to more effectively combat P. aeruginosa infections.

RESUMO

Resumen Existe controversia sobre el efecto preconsciente del priming con dinero sobre el comportamiento (Rohrer, Pasher & Harris, 2015). Supuestamente, los evocadores de riqueza mediante técnicas de priming provocan que la gente entre en un estado de autosuficiencia (Vos, Mead & Goode, 2006) en el que optan por comportamientos individualistas y se sienten más capaces. Dicho estado ha sido asociado con un aumento en la intención y conducta deshonesta (Kouchaki, Smith-Crowe, Brief & Sousa, 2013). Para confirmar la robustez de los efectos anteriores se desarrollaron dos experimentos de tres grupos experimentales y un experimento factorial de 3x2 en los que se puso a prueba si la manipulación de dinero afectaba la intención deshonesta, y la conducta deshonesta en una prueba concreta así como en una tarea abstracta. No se encontraron diferencias estadísticamente significativas entre los puntajes de intención deshonesta (F (2,57)= 0.163, p=.850; η2p=0.06), ni entre los puntajes de deshonestidad concreta (F (2,114)= 0.582, p=0.560; η2p=0.010) ni en los de deshonestidad abstracta (χ2(2)=2.360, p=0.307). Contrariamente a lo esperado, los grupos estimulados con dinero fueron los que reportaron menor intención y conducta deshonesta. Ello podría indicar que el dinero actuó más como un evocador de honestidad o responsabilidad, más que de deshonestidad.

Abstract Effects of money-related primes over behavior seem inconclusive amongst researchers (Rohrer, Pasher & Harris, 2015). According to Vohs, Mead and Goode (2006) money primes induce people into a state of self-sufficiency, in which they prefer actions selected by themselves and feel more capable. Such state has been positively associated to dishonest intention and behavior (Kouchaki, Smith-Crowe, Brief & Sousa, 2013). To confirm the robustness of these effects, we designed two three-group experiments, and a 3x2 factorial experiment, testing if handling money affected dishonest intention, and dishonest behavior on a concrete task as well as on an abstract task. There were no statistically significant differences between dishonest intention scores (F (2,57)= 0.163, p=0.850; η2p=0.06), concrete-task dishonesty scores (F (2,114)= 0.582, p=0.560; η2p=0.010) or abstract-task dishonesty scores (χ2(2)=2.360, p=0.307). Contrary to what was expected, money-primed groups reported a lower dishonest intention and behavior. This could mean that money acted more as a reminder of honesty or responsibility than a reminder of dishonesty.

RESUMO

Quorum sensing (QS) in Pseudomonas aeruginosa coordinates the expression of virulence factors, such as exoproteases and siderophores, that are public goods utilized by the whole population of bacteria, regardless of whether they invested or not in their production. These public goods can be used by QS defective mutants for growth, and since these mutants do not contribute to public goods production, they are considered social cheaters. Pyocyanin is a phenazine that is a toxic, QS-controlled metabolite produced by P. aeruginosa. It is a redox-active compound and promotes the generation of reactive oxygen species; it also possesses antibacterial properties and increases fitness in competition with other bacterial species. Since QS-deficient individuals are less able to tolerate oxidative stress, we hypothesized that the pyocyanin produced by the wild-type population could promote selection of functional QS systems in this bacterium. Here, we demonstrate, using competition experiments and mathematical models, that, indeed, pyocyanin increases the fitness of the cooperative QS-proficient individuals and restricts the appearance of social cheaters. In addition, we also show that pyocyanin is able to select QS in other bacteria such as Acinetobacter baumannii.

RESUMO

Quorum sensing (QS) in Pseudomonas aeruginosa coordinates the expression of virulence factors, some of which are used as public goods. Since their production is a cooperative behavior, it is susceptible to social cheating in which non-cooperative QS deficient mutants use the resources without investing in their production. Nevertheless, functional QS systems are abundant; hence, mechanisms regulating the amount of cheating should exist. Evidence that demonstrates a tight relationship between QS and the susceptibility of bacteria against the attack of lytic phages is increasing; nevertheless, the relationship between temperate phages and QS has been much less explored. Therefore, in this work, we studied the effects of having a functional QS system on the susceptibility to temperate bacteriophages and how this affects the bacterial and phage dynamics. We find that both experimentally and using mathematical models, that the lysogenic bacteriophages D3112 and JBD30 select QS-proficient P. aeruginosa phenotypes as compared to the QS-deficient mutants during competition experiments with mixed strain populations in vitro and in vivo in Galleria mellonella, in spite of the fact that both phages replicate better in the wild-type background. We show that this phenomenon restricts social cheating, and we propose that temperate phages may constitute an important selective pressure toward the conservation of bacterial QS.

RESUMO

In the mutualism established between legumes and soil bacteria known as rhizobia, bacteria from soil infect plants roots and reproduce inside root nodules where they fix atmospheric N2 for plant nutrition, receiving carbohydrates in exchange. Host-plant sanctions against non N2 fixing, cheating bacterial symbionts have been proposed to act in the legume-Rhizobium symbiosis, to preserve the mutualistic relationship. Sanctions include decreased rhizobial survival in nodules occupied by cheating rhizobia. Previously, a simple population model experimentally based showed that the coexistence of fixing and cheating rhizobia strains commonly found in field conditions is possible, and that the inclusion of sanctions leads to the extinction of cheating strains in soil. Here, we extend the previous model to include other factors that could complicate the sanction scenario, like horizontal transmission of symbiotic plasmids, turning non-nodulating strains into nodulating rhizobia, and competition between fixing and cheating strains for nodulation. In agreement with previous results, we show that plant populations persist even in the presence of cheating rhizobia without incorporating any sanction against the cheater populations in the model, under the realistic assumption that plants can at least get some amount of fixed N2 from the effectively mutualistic rhizobia occupying some nodules. Inclusion of plant sanctions leads to the unrealistic extinction of cheater strains in soil. Our results agree with increasing experimental evidence and theoretical work showing that mutualisms can persist in presence of cheating partners.

RESUMO

Plagiarism is a serious, yet widespread type of research misconduct, and is often neglected in developing countries. Despite its far-reaching implications, plagiarism is poorly acknowledged and discussed in the academic setting, and insufficient evidence exists in Latin America and developing countries to inform the development of preventive strategies. In this context, we present a longitudinal case study of seven instances of plagiarism and cheating arising in four consecutive classes (2011-2014) of an Epidemiology Masters program in Lima, Peru, and describes the implementation and outcomes of a multifaceted, "zero-tolerance" policy aimed at introducing research integrity. Two cases involved cheating in graded assignments, and five cases correspond to plagiarism in the thesis protocol. Cases revealed poor awareness of high tolerance to plagiarism, poor academic performance, and widespread writing deficiencies, compensated with patchwriting and copy-pasting. Depending on the events' severity, penalties included course failure (6/7) and separation from the program (3/7). Students at fault did not engage in further plagiarism. Between 2011 and 2013, the Masters program sequentially introduced a preventive policy consisting of: (i) intensified research integrity and scientific writing education, (ii) a stepwise, cumulative writing process; (iii) honor codes; (iv) active search for plagiarism in all academic products; and (v) a "zero-tolerance" policy in response to documented cases. No cases were detected in 2014. In conclusion, plagiarism seems to be widespread in resource-limited settings and a greater response with educational and zero-tolerance components is needed to prevent it.

RESUMO

Prior research has found that humiliating marital events are associated with depression. Building on this research, the current study investigated the association between one specific humiliating marital event-discovering that one's partner had an affair-and past-year major depressive episode (MDE) in a probability sample of married or cohabiting men and women who were at high risk for depression based on the criterion that they scored below the midpoint on a measure of marital satisfaction (N = 227). Results indicate that (i) women were more likely than men to report discovering their partner had an affair in the prior 12 months; (ii) discovering a partner affair was associated with a higher prevalence of past-year MDE and a lower level of marital adjustment; and (iii) the association between discovering a partner affair and MDE remained statistically significant when holding constant demographic variables and marital adjustment. These results support continued investigation into the impact that finding out about an affair has on the mental health of the person discovering a partner affair.

RESUMO

The metabolic capabilities of microbes are the basis for many major biotechnological advances, exploiting microbial diversity by selection or engineering of single strains. However, there are limits to the advances that can be achieved with single strains, and attention has turned toward the metabolic potential of consortia and the field of synthetic ecology. The main challenge for the synthetic ecology is that consortia are frequently unstable, largely because evolution by constituent members affects their interactions, which are the basis of collective metabolic functionality. Current practices in modeling consortia largely consider interactions as fixed circuits of chemical reactions, which greatly increases their tractability. This simplification comes at the cost of essential biological realism, stripping out the ecological context in which the metabolic actions occur and the potential for evolutionary change. In other words, evolutionary stability is not engineered into the system. This realization highlights the necessity to better identify the key components that influence the stable coexistence of microorganisms. Inclusion of ecological and evolutionary principles, in addition to biophysical variables and stoichiometric modeling of metabolism, is critical for microbial consortia design. This review aims to bring ecological and evolutionary concepts to the discussion on the stability of microbial consortia. In particular, we focus on the combined effect of spatial structure (connectivity of molecules and cells within the system) and ecological interactions (reciprocal and non-reciprocal) on the persistence of microbial consortia. We discuss exemplary cases to illustrate these ideas from published studies in evolutionary biology and biotechnology. We conclude by making clear the relevance of incorporating evolutionary and ecological principles to the design of microbial consortia, as a way of achieving evolutionarily stable and sustainable systems.

RESUMO

El presente estudio expone las características de la conducta deshonesta en el aula, describe sus causas y examina las nefastas consecuencias que tiene para el aprendizaje. Con el fin de analizar el estado de la cuestión en nuestro país, se ha hecho una entrevista psicoeducativa y se ha aplicado un cuestionario a un total de 306 alumnos de último curso de bachillerato, último curso de universidad y último curso de Psicología en Barcelona (España). Se ha comprobado que, igual cómo ocurre en otros países, más de la mitad de los estudiantes reconocen tener el hábito de copiar, y también que los chicos copian más que las chicas. Para finalizar, el trabajo expone estrategias operativas para controlar la conducta deshonesta en el aula, que incluyen: incorporar contenidos relacionados con la ética en el currículum, enseñar técnicas de análisis y resumen para evitar que los alumnos se vean obligados a copiar, y ser muy estrictos con las fechas límite y la aplicación de las normas en las instituciones educativas.

The aim of this paper is to present the issue of academic cheating, describe its causes, and examine the obstacles this behaviour creates for learning. The research was carried out with 306 students from Barcelona (Spain) which were administered both with a psycho educational interview and a questionnaire. Results are similar to those from other countries and show that more than half of the students are in the habit of frequently cheating, and that boys cheat significantly more often than girls. To finish, the text suggests teaching strategies to control academic cheating in educational institutions, such as: Being aware of the problem and taking the decision to tackle it, including ethics tuition in the curricular content, teaching summarising and rephrasing techniques, frequently revising students’ writings, and last but not least, being very strict with deadlines and not accepting unwarranted excuses repeatedly made by students for not observing them.

RESUMO

Background: The prevalence of academic delinquency in universities, predominantly in the form of plagiarism and cheating, is extensively conceded. Objectives: The objective of this study was to evaluate student’s perception and behavior towards plagiarism in Pakistani universities. Methods: This cross-sectional survey was conducted in 6 academic disciplines in 35 universities in Pakistan during 21.02.2011-21.04.2011. Expert interviewers and learned educationists carried out the interviews with the help of a structured questionnaire to evaluate student’s knowledge about plagiarism such as (i) student’s knowledge about HEC policy, (ii) student’s attitude towards plagiarism, (iii) student’s satisfaction towards plagiarism and cheating, and (iv) their views for penalties (What should be the penalties for 1st and 2nd occurrence of plagiarism?) and recorded the responses. Results: This survey was accomplished by 25742 students. The response rate for awareness about HEC policy about plagiarism showed that significantly (p<0.05) low percentage (94 percent of students was unaware of this policy. The attitudes of significantly (p<0.05) high percentage of students towards plagiarism behavior were unacceptable. Significantly (p<0.05) high response rate towards attitudes regarding punishment for plagiarism was warning and report to HOD for first and second occurrence of this cheating, respectively. Conclusions: An extensive lack was found in the understanding of students towards plagiarism across all the universities. It is necessary to achieve balance between factors affecting plagiarism such avoidance, finding and sentence in case of detection.

RESUMO

Este estudo tem por objetivo investigar, em uma perspectiva psicogenética, a trapaça no que diz respeito ao juízo moral de crianças em uma situação de jogos de regras, com base na teoria piagetiana. Participaram desta, 40 crianças de duas escolas particulares do município de Linhares - ES, com idades de 5 e 10 anos, distribuídas igualmente de acordo com a idade e o sexo. Realizamos esta pesquisa utilizando os seguintes instrumentos: uma história e um roteiro de entrevista envolvendo a trapaça no Jogo da Velha. A pesquisa foi realizada em uma fase, na qual procurávamos conhecer o juízo moral da criança a respeito da trapaça. Os resultados nos permitiram observar que a totalidade dos participantes, ao ser solicitado que expressassem um juízo a respeito da atitude narrada, disse que a atitude de trapacear estava errada, sendo que o maior número de justificativas mencionadas entre as crianças de 5 anos foi baseada em 'argumentos circulares'. Em contrapartida, a categoria citada mais vezes pelos participantes de 10 anos foi 'desobedeceu à regra do jogo'. Por meio destes resultados, foi possível notar que as crianças de ambas as idades pesquisadas julgavam a trapaça como algo errado. Além disso, associaram as suas concepções a vários aspectos morais já conhecidos, como o roubo e a mentira. © Cien. Cogn. 2011; Vol. 16 (3): 167-185.

Abstract This study aims to investigate, in a psychogenic perspective, cheating regarding children's moral judgment in a situation of games with rules, based on Piaget's theory. 40 children from two private schools in Linhares town - ES participated, with ages between 5 and 10 years, equally distributed according to age and sex. This research was conducted using the following instruments: a story and a structured interview involving cheating on Tic Tac Toe. The survey was conducted in a phase in which it was sought to know the child's moral judgments regarding the cheating. The results allowed to observe that when being asked to establish an opinion on the attitude reported, all of the participants said that the act of cheating was wrong, with the largest number of justifications mentioned among children 5 years was 'circular argument'. However, the category most often cited by participants of 10 years was 'disobeyed the rules of the game'. Through these results, it was noticeable that the children from both ages that were surveyed think of cheating as something wrong. Besides, they associate their views through various moral aspects, which are already known, such as stealing and lying. © Cien. Cogn. 2011; Vol. 16 (3): 167-185.
