Mental budgeting and the malleability of decision-making

Financial difficulties commonly occur in college students' lives. Problems might be caused by a lack of understanding about managing money, such as falling into the temptation of buying unnecessary discounted goods or choice justification. The research aims to understand how mental budgeting influences purchasing discounted items and choice justification. In the study, two experiments were undertaken to explain the reaction of discount, and two others to describe choice justification (N=169 in Indonesia, N=168 in China). Mann-Whitney U and ANOVA tests were used to analyze the experiments. Mental budgeting scales were also employed in experiments 3 and 4. The results show that when individuals receive a discounted offer for luxury goods, they will fall into the temptation of buying them. This takes place because they do not want to lose the opportunity to obtain such goods at a cheap price. In addition, when individuals receive offers related to physiological needs (i.e., food), they will practice choice justification. This means that all people need to understand the concept of mental budgeting and make realistic budgets

Traveling Wave Solutions for Planar Lattice Differential Systems with Applications to Neural Networks

AbstractWe obtain some existence results for traveling wave fronts and slowly oscillatory spatially periodic traveling waves of planar lattice differential systems with delay. Our approach is via Schauder's fixed-point theorem for the existence of traveling wave fronts and via S1-degree and equivarant bifurcation theory for the existence of periodic traveling waves. As examples, the obtained abstract results will be applied to a model arising from neural networks and explicit conditions for traveling wave fronts and global continuation of periodic waves will be obtained

Good news or bad news, which do you want first? The importance of the sequence and organization of Information for financial decision-making: a neuro-electrical imaging study

Investment decisions are largely based on the information investors received from the target firm. Thaler introduced the hedonic editing framework, in which suggests that integration/segregation of information influence individual's perceived value. Meanwhile, when evaluating the evidence and information in a sequence, order effect and biases have been found to have an impact in various areas. In this research, the influence of the Organization of Information (Integration vs. Segregation) and the Sequence of Information (Negative-Positive order vs. Positive-Negative order) on individual's investment decision-making both at the behavioral level (decision) and neurometrix level (measured by an individual's emotion and Approach Withdraw tendency) was assessed for the three groups of information: a piece of Big Positive Information and a piece of Small Negative Information, a piece of Big Negative Information and a piece of Small Positive Information, and a piece of Small Negative information. The behavioral results, which are an individual's final investment decision, were consistent for all three scenarios. In general, individuals will invest more/retire less when receiving two pieces of information in a Negative-Positive order. However, the neurometric results (Emotional Index, Approach Withdraw Index and results from LORETA) show differences among information groups. An effect of the Sequence of Information and the Organization of Information was found for the different scenarios. The results suggest that in the scenarios that involve large-scale information, the organization of information (Integration vs. Segregation) influences the emotion and Approach Withdraw tendency. The results of this investigation should provide insight for effective communication of information, especially when large-scale information is involved

Expression, Purification, and Mechanistic Studies of Bovine Mitochondrial Translational Initiation Factor 2

A complete cDNA clone encoding bovine mitochondrial translational initiation factor 2 (IF-2mt) has been obtained. The regions of the cDNA corresponding to mature IF-2mt and several of its functional domains have been expressed in Escherichia coli as histidine-tagged proteins. The precursor (approximately 90 kDa) and mature (approximately 85 kDa) forms of IF-2mt are toxic to E. coli and can only be expressed at low levels. Shorter forms of this factor (approximately 80 and approximately 72 kDa) are also found during the expression of mature IF-2mt. The various forms of IF-2mt can be separated by high performance liquid chromatography. All of these forms are active in promoting the GTP-dependent binding of formyl-Met-tRNA to the small subunit of either E. coli or bovine mitochondrial ribosomes. IF-2mt can bind to mitochondrial ribosomes in the absence of GTP, initiator tRNA, or messenger RNA. The presence of GTP stimulates IF-2mt binding to ribosomes about 3-fold. IF-2mt interacts only weakly with GTP or with the initiator tRNA in the absence of ribosomes. Molecular dissection of IF-2mt shows that a long deletion (approximately 150 amino acid residues) from the NH2-terminal region does not affect its activity in vitro. The COOH domain of IF-2mt (amino acid residues 332-727) can bind to ribosomes even though it does not promote initiator-tRNA binding

Personal control and organizational coping strategies of job stress : empirical results from China

The purpose of the present study is first to examine the relationship between organizational strategies and job stress, taking the assumption that personal control will mediate the underlying organizational strategies-job stress connection, and then to develop stress copings by recombining management with regard to their impact on personal control. Further, the role of educational level and types of jobs on job stress will also be examined

Expanding social, psychological, and physical indicators of urbanites' life satisfaction toward residential community: a structural equation modeling analysis

Attention on, and interest in, life satisfaction has increased worldwide. However, research on life satisfaction focused toward the urban dwellers' residential community is mainly from western countries, and the limited research from China is solely focused on the geriatric population via a narrowly constrained research perspective. This study, therefore, aimed to investigate urbanites' life satisfaction toward their community, combining the psychological (behavioral community engagement, mental state of flow, and cognitive community identity), physical (PREQIs-perceived residential environment quality indicators: e.g., green area), and social perspectives (social capital). The proposed conceptual model was tested on a regionally representative sample of 508 urban community residents in the city of Chengdu, Sichuan province, China. Data were analyzed via a structure equation modelling approach in AMOS software. Findings suggested that all of the psychological, physical and social factors contributed to a prediction of life satisfaction. Specifically, social capital mediated the path from community engagement and flow to life satisfaction, and community identity mediated the path from flow experience and green area to life satisfaction. Additionally, social capital contributed to predict life satisfaction through its influence on community identity. Findings provide suggestions for urban designers and policymakers to focus on creating an urban community equipped with green area, which helps to promote physical activities that are flow-productive, to enhance residents' identification to their residential community and, therefore, increase life satisfaction

Co-Check: Collaborative Outsourced Data Auditing in Multicloud Environment

With the increasing demand for ubiquitous connectivity, wireless technology has significantly improved our daily lives. Meanwhile, together with cloud-computing technology (e.g., cloud storage services and big data processing), new wireless networking technology becomes the foundation infrastructure of emerging communication networks. Particularly, cloud storage has been widely used in services, such as data outsourcing and resource sharing, among the heterogeneous wireless environments because of its convenience, low cost, and flexibility. However, users/clients lose the physical control of their data after outsourcing. Consequently, ensuring the integrity of the outsourced data becomes an important security requirement of cloud storage applications. In this paper, we present Co-Check, a collaborative multicloud data integrity audition scheme, which is based on BLS (Boneh-Lynn-Shacham) signature and homomorphic tags. According to the proposed scheme, clients can audit their outsourced data in a one-round challenge-response interaction with low performance overhead. Our scheme also supports dynamic data maintenance. The theoretical analysis and experiment results illustrate that our scheme is provably secure and efficient
