Examining the Distinct Antecedents of E‐Mail Habits and its Influence on the Outcomes of a Phishing Attack

While research has linked social media phishing susceptibility to individual Facebook habits, the underlying process by which habits lead to victimization and the extent to which it explains e‐mail‐based phishing remains unclear. The study compared the antecedents and consequences of e‐mail habits and cognitive processing on the outcome of a simulated phishing attack. E‐mail habits were rooted in stable personality dimensions of conscientiousness and emotional stability, while cognitive processing was premised on contextual information adequacy considerations. Interestingly, habits and processing jointly influenced the outcome of the attack: Systematic processing attenuated phishing susceptibility by a small factor; the cumulative effects of heuristic processing and e‐mail habits, however, caused a fourfold increase in likely victimization, overwhelming any advantage from detailed processing.     

A study of e‐mail patterns

Although electronic mail is an increasingly important service, there are few empirical studies of e‐mail traffic. We have observed over 2.85 million messages passing through our departmental servers over the course of seven months, and derived distributions that approximate several important e‐mail parameters including message sizes, message senders and receivers and the burstiness of message deliveries. Our work is unique in that we also analyse message payloads: attachment content types, e‐mail redundancy, and the use of e‐mail as a sharing mechanism. These data can be used in developing e‐mail workloads for mail system engineering or benchmarking. To this end, we provide an improved version of Postmark, a small‐file Internet benchmark, that better approximates mail server characteristics. Copyright © 2007 John Wiley & Sons, Ltd.     

Students' Perceptions of E‐Mail Interaction During Student‐Professor Advising Sessions: The Pursuit of Interpersonal Goals

This study investigated students' preference for e‐mail over face‐to‐face (FtF) communication for interpersonal goal achievement (i.e., instrumental, relational, self‐presentational) with faculty advisors. An exploratory analysis of undergraduate students revealed that they did not prefer computer‐mediated communication (i.e., e‐mail) over FtF communication with advisors when addressing all 3 interpersonal goal types. Significant gender differences were also found, with women reporting more use of e‐mail, and men preferring to address self‐presentational goals in FtF settings. It also was found that compared to Caucasians, African Americans did not prefer CMC to FtF interaction in achieving instrumental and self‐presentational goals. Results of this study suggest that despite the ubiquity of e‐mail communication, undergraduates did not prefer e‐mail over FtF contact with faculty advisors.     

Organizational Norm Congruency and Interpersonal Familiarity in E‐Mail: Examining Messages From Two Different Status Perspectives

Relying on SIDE theory, this 2 × 2 experimental design tested the effects of adherence to organizational norms and interpersonal familiarity in e‐mail messages from both superior and subordinate perspectives. Results reveal that using norm‐congruent e‐mail messages account for over 50% of the variance in both superior and subordinate attitudes toward the message and between 30% and 56% of the variance in perceptions of source credibility. Data from the superiors indicate that norm congruent e‐mail messages account for 14.4% of the variance in message compliance. Results from subordinates reveal an interaction effect that is consistent with SIDE‐based predictions. Subordinates believe superiors are most likely to comply with e‐mail requests from unfamiliar subordinates that are crafted in a manner congruent with organizational norms.     

移动元胞自动机的个体化网络舆情聚类模型与仿真

为了研究舆情个体的个性对现实环境下网络舆情传播和演化的影响以及舆情个体“类聚”现象,采用元胞自动机理论的建模方法,将一定网格空间的个体抽象为带有情感倾向度的元胞,设定离散值的意见倾向度。此外,定义元胞的个体特性：坚定性权重[βij],个体影响权重[λij]。为了模拟舆情个体可以通过不同途径参与舆情事件,定义了一种新的移动规则,在边界周期条件下的元胞空间,实现了每个元胞与空间内的所有元胞的信息交流。实验结果表明：舆情演化到最后会呈现稳定状态,舆情个体的不同个性会影响稳态收敛的速度快慢;当个体特性取中间值时,系统最有可能出现意见群体意见归一现象。

A forward-secure e-mail protocol without certificated public keys

Forward secrecy in an e-mail system means that compromising of the long-term secret keys of the mail users and mail servers does not affect the confidentiality of the e-mail messages. Previous forward-secure e-mail protocols used the certified public keys of the users using PKI (Public Key Infrastructure). In this paper, we propose a password-based authenticated e-mail protocol providing forward secrecy. The proposed protocol does not require certified public keys and is sufficiently efficient to be executed on resource-restricted mobile devices.     

Exploring university perceptions of IS implementation and attributes of success: a case study of public universities in Thailand

ABSTRACT

This study aims to gain a better understanding of public university implementation of organizational information systems (IS). Mixed methods research was used, including initial exploration, telephone interviews, and a self-administered mail survey. The data were gathered from university personnel at 40 public universities in Thailand, and the research focused on the university student-registration systems (S-R). The study results highlight the different perceptions between two response groups: administrators and system users. The results show different perceptions of IS implementation and attributes that define IS implementation success. The results also serve as important suggestions that need to be recognized by administrators and practitioners for effectively planning the implementation of organizational IS in public universities.

The Role of Social Network Sites in Romantic Relationships: Effects on Jealousy and Relationship Happiness

On social network sites (SNS), information about one's romantic partner is readily available and public for friends. The paper focuses on the negative (SNS jealousy) and positive (SNS relationship happiness) consequences of SNS use for romantic relationships. We examined whether relationship satisfaction, trait jealousy, SNS use and need for popularity predicted these emotional consequences of SNS use and tested the moderating role of self‐esteem. For low self‐esteem individuals, need for popularity predicted jealousy and relationship happiness. For high‐self‐esteem individuals, SNS use for grooming was the main predictor. Low‐self‐esteem individuals try to compensate their low self‐esteem by creating an idealized picture. Undesirable information threatens this picture, and especially individuals with a high need for popularity react with SNS jealousy.

Social skills as predictors of communication,performance and quality of collaboration in project‐based learning

The assumption that social skills are necessary ingredients of collaborative learning is well established but rarely empirically tested. In addition, most theories on collaborative learning focus on social skills only at the personal level, while the social skill configurations within a learning group might be of equal importance. Using the integrative framework, this study investigates which social skills at the personal level and at the group level are predictive of task‐related e‐mail communication, satisfaction with performance and perceived quality of collaboration. Data collection took place in a technology‐enhanced long‐term project‐based learning setting for pre‐service teachers. For data collection, two questionnaires were used, one at the beginning and one at the end of the learning cycle which lasted 3 months. During the project phase, the e‐mail communication between group members was captured as well. The investigation of 60 project groups (N = 155 for the questionnaires; group size: two or three students) and 33 groups for the e‐mail communication (N = 83) revealed that personal social skills played only a minor role compared to group level configurations of social skills in predicting satisfaction with performance, perceived quality of collaboration and communication behaviour. Members from groups that showed a high and/or homogeneous configuration of specific social skills (e.g., cooperation/compromising, leadership) usually were more satisfied and saw their group as more efficient than members from groups with a low and/or heterogeneous configuration of skills.     

Effects of Duration and Laughter on Subjective Happiness Within Different Modes of Communication

Media naturalness theory and social information processing theory make competing predictions regarding the effectiveness of different modes of communication at creating and maintaining emotionally intense social relationships. We explored how the duration of interaction and the form of laughter influenced happiness in communication modes with different levels of media naturalness. Forty‐one participants completed a 14‐day contact diary, recording interactions across face‐to‐face, Skype, telephone, instant messaging, texting, and e‐mail/social network sites. Increases in duration of interaction positively predicted happiness only for face‐to‐face interactions, offering partial support for the media naturalness hypothesis. Laughter positively predicted happiness in all but one of the communication modes, with real and symbolic laughter having similar effects, a result consistent with the social information processing theory.

A proxy approach to e‐mail security

New Internet applications and new releases of existing Internet applications appear with bewildering rapidity. Adding functionality to such applications can therefore be a time‐consuming process. By contrast, Internet protocols are significantly less volatile. In some circumstances, the additional functionality can be provided by ‘tapping into’ the protocol exchanges rather than modifying the applications themselves. We claim that this represents a more manageable approach to the problem of adding additional facilities to applications. We demonstrate this approach using the example of e‐mail security. Whenever possible, a proxy sitting between a mail client and server signs and encrypts outgoing mail. Incoming secured mail is automatically decrypted and verified. This means that any software that works with standard mail protocols gains security without requiring separate upgrading. The proxy attempts to keep the amount of user interaction required to a minimum providing security functionality for users without the need to learn a complex new user interface.Copyright © 1999 John Wiley & Sons, Ltd.     

Short and Sweet? Length and Informative Content of Open‐Ended Responses Using SMS as a Research Mode

Short Message Service (SMS) is one of the most widely used data services worldwide. This paper examines the assumption that the 160‐character limit would force brief and thus comparatively uninformative responses in psychological research compared to other data collection modes. In laboratory classes, 463 psychology undergraduate students were randomly assigned to complete a 2‐item questionnaire by SMS, e‐mail, online survey, or paper survey. 2 weeks later, participants completed a multiple‐choice self‐report risk taking questionnaire on paper. While SMS response lengths were statistically significantly shorter than those yielded in other modes, they did not contain less information.

Complementary Channel Use and the Role of Social Competence

This study focused on channel complementarity among various interpersonal communication channels (face‐to‐face, telephone, e‐mail, text messaging, and Facebook). We looked at daily channel use among 136 participants and demonstrated complementary channel use among most combinations of channels, excluding face‐to‐face. We also extended channel complementarity theory by examining social competence as a moderator of channel complementarity. Results indicated that telephone and text messaging exhibited complementarity at high but not low levels of social competence, whereas e‐mail and text messaging exhibited complementarity at low but not high levels of social competence. Face‐to‐face communication and Facebook exhibited a displacement relationship at high but not low levels of social competence. Implications for channel complementarity theory and the role of individual characteristics are discussed.
