Visual pattern memory requires foraging function in the central complex of Drosophila

The role of the foraging (for) gene, which encodes a cyclic guanosine-3',5'-monophosphate (cGMP)-dependent protein kinase (PKG), in food-search behavior in Drosophila has been intensively studied. However, its functions in other complex behaviors have not been well-characterized. Here, we show experimentally in Drosophila that the for gene is required in the operant visual learning paradigm. Visual pattern memory was normal in a natural variant rover (for(R)) but was impaired in another natural variant sitter (for(S)), which has a lower PKG level. Memory defects in for(S) flies could be rescued by either constitutive or adult-limited expression of for in the fan-shaped body. Interestingly, we showed that such rescue also occurred when for was expressed in the ellipsoid body. Additionally, expression of for in the fifth layer of the fan-shaped body restored sufficient memory for the pattern parameter "elevation" but not for "contour orientation," whereas expression of for in the ellipsoid body restored sufficient memory for both parameters. Our study defines a Drosophila model for further understanding the role of cGMP-PKG signaling in associative learning/memory and the neural circuit underlying this for-dependent visual pattern memory.     

Upregulation of hippocampal TrkB and synaptotagmin is involved in treadmill exercise-enhanced aversive memory in mice

Cognitive functions usually involve various synaptic proteins and neurotrophic factors in the hippocampus. However, whether treadmill exercise can improve learning and memory by upregulating some of these molecules remain unraveled. To address this question, male BALB/c mice were divided into control and exercise groups, the latter group went through 4 weeks of treadmill exercise training. At the end of exercise training period, they were either tested for passive avoidance (PA) performance or sacrificed for quantifying the hippocampal levels of brain-derived neurotrophic factor (BDNF), tropomyosin-related kinase B (TrkB, the BDNF receptor), synaptotagmin (a Ca²⁺-dependent synaptic vesicle protein), and SNAP-25 (a presynaptic vesicular fusion protein). Our results showed that treadmill exercise training (1) increased the retention latency without affecting the fear acquisition in the PA test, (2) transiently increased the hippocampal BDNF level at 1, 2, and 4 h after the completion of exercise training, and (3) persistently increased the hippocampal protein levels of full-length TrkB, phosphorylated TrkB and synaptotagmin, but not truncated TrkB or SNAP-25. Moreover, the protein expression level of full-length TrkB or synaptotagmin was positively correlated with PA performance in mice. Finally, inhibition of TrkB signaling by K252a abolished the exercise-facilitated PA performance and upregulation of TrkB and synaptotagmin. Taken together, these data suggest that the upregulation of TrkB and synaptotagmin in the hippocampus contributes to the exercise-facilitated aversive memory.     

Reversible disconnection of the hippocampal-prelimbic cortical circuit impairs spatial learning but not passive avoidance learning in rats

Wistar rats, treated with the GABA(A) receptor agonist muscimol, were used to investigate the role of the hippocampal-prelimbic cortical (Hip-PLC) circuit in spatial learning in the Morris water maze task, and in passive avoidance learning in the step-through task. In the water maze task, animals were trained for three consecutive days and tested 24 h after the end of training. In the step-through task, the animals were trained once and tested 24h after training. On the training days, daily infusion of muscimol (0.5 microg/0.25 microl) was given (1) bilaterally to the ventral hippocampus (vHip), (2) bilaterally to the prelimbic cortex (PLC), (3) to the unilateral vHip and the ipsilateral PLC, or (4) for disconnecting the Hip-PLC circuit, to both the unilateral vHip and the contralateral PLC 30 min before training. The results showed that inhibition of the vHip resulted in disruption of performance in both tasks. Inhibition of the PLC produced impaired water maze performance, but had no effect on the step-through task. Disconnection of the Hip-PLC circuit produced similar effects to PLC inhibition. However, simultaneous inhibition of the unilateral vHip and the ipsilateral PLC had little effect on performance of the water maze task. The results suggested that spatial learning depends on the Hip-PLC circuit, whereas passive avoidance learning is independent of this circuit.     

Personality traits and life satisfaction among online game players.

The DFC Intelligence predicts worldwide online game revenues will reach $9.8 billion by 2009, making online gaming a mainstream recreational activity. Understanding online game player personality traits is therefore important. This study researches the relationship between personality traits and life satisfaction in online game players. Taipei, Taiwan, is the study location, with questionnaire surveys conducted in cyber cafe shops. Multiple regression analysis studies the causal relationship between personality traits and life satisfaction in online game players. The result shows that neuroticism has significant negative influence on life satisfaction. Both openness and conscientiousness have significant positive influence on life satisfaction. Finally, implications for leisure practice and further research are discussed.     

Detecting impossible changes in infancy: a three-system account

Can infants detect that an object has magically disappeared, broken apart or changed color while briefly hidden? Recent research suggests that infants detect some but not other 'impossible' changes; and that various contextual manipulations can induce infants to detect changes they would not otherwise detect. We present an account that includes three systems: a physical-reasoning, an object-tracking, and an object-representation system. What impossible changes infants detect depends on what object information is included in the physical-reasoning system; this information becomes subject to a principle of persistence, which states that objects can undergo no spontaneous or uncaused change. What contextual manipulations induce infants to detect impossible changes depends on complex interplays between the physical-reasoning system and the object-tracking and object-representation systems.     

Socially oriented values and reciprocity norm predict organizational commitment

The current research concerns the predictors and organizational outcomes of normative commitment in Chinese companies. In Study 1, using a semi-structured interview, we identified internalization of socially oriented value and reciprocity norm as two possible predictors of normative commitment. Survey results confirm the factorial independence of these two predictors. Study 2 examined the predictive relationship of these predictors with employee job satisfaction, turnover intention, in-role performance, and organizational citizenship behaviour (OCB). The results showed that value internalization predicts higher job satisfaction and weaker turnover intentions via normative commitment, whereas reciprocity predicts higher job satisfaction, weaker turnover intention, and more frequent display of OCB via normative commitment. These findings are discussed in terms of their implications for future research and management practices.     

儒家经典英译与儒家思想的跨文化传播

儒家经典是中国传统文化的瑰宝。儒家经典的外译特别是英译,一直是西方国家了解中国文化的重要途径之一,也为西方读者提供了更为广阔的欣赏儒家思想的空间。儒家经典英译其本质是一种跨文化传播活动。儒家经典众多的译本由于译者的背景、传播目的和目标受众的不同,也呈现出不同的风格。     

试论孟子与士人精神

作为中国“轴心时代”的重要思想家,孟子希望以道德化政治,实现天下有道。他提出士人修养的“浩然之气”,在士人与君主的关系上主张“道高于君”,而对于广大普通民众则倡导“使先知觉后知,使先觉觉后觉”。在此基础上,孟子推出了四种士人典范。而在孟子这些思想中,一以贯之的乃是对德性的张扬,在“尊德性”与“道问学”之间,他明显偏重于前者,这是孟子关于士人精神的特色所在。在孟子的精神世界里,我们可以看到的更多的是一种道德信仰和勇气。正是从这个意义上讲,孟子是一位信仰道德的“宗教家”,而不是一位代表智性的“学问家”。
