Adoption of O2O food delivery services in South Korea: The moderating role of moral obligation in meal preparation

Most studies on O2O services have focused solely on the technological merits of mobile applications, overlooking the role of the value systems that underlie people’s lifestyles.In contrast, this research sheds light on how people’s value systems influence their decision to adopt food delivery applications. Particularly, it proposes that people’s moral obligation in meal preparation can change the mode of thinking that guides their adoption decision. Namely, moral obligation is assumed to restrict people from acting on their basic convenience orientation in meal preparation. Empirical results have supported this assumption by showing that people with a high moral obligation (or married people) are more reluctant to convert their basic convenience-seeking tendencies into actual adoption intention than those with a low moral obligation (or single people). The important theoretical and managerial implications of these results are also discussed.

Unique unto itself: The records of the Federal Bureau of Investigation 1908 to 1945

This paper addresses several misunderstandings about the nature of the FBI's Central Records System. Although depicted in popular culture and much of FBI historiography as a tool for the Cold War suppression of American radicals, the FBI's records system grew out of Department of Justice systems already in place before J. Edgar Hoover became Director in 1924. The system grew in size and complexity according to the demands placed on it by the changing priorities of the FBI's criminal and intelligence missions, guided by a “progressive” drive for efficiency through centralization.     

Teaching principles of inference with ANOVA

Analysis of variance (ANOVA) is a test of mean differences, but the reference to variances in the name is often overlooked. Classroom activities are presented to illustrate how ANOVA works with emphasis on how to think critically about inferential reasoning.     

More Powerful Tests of Simple Interaction Contrasts in the Two-Way Factorial Design

For the two-way factorial design in analysis of variance, the current article explicates and compares three methods for controlling the Type I error rate for all possible simple interaction contrasts following a statistically significant interaction, including a proposed modification to the Bonferroni procedure that increases the power of statistical tests for deconstructing interaction effects when they are of primary substantive interest. Results indicate the general superiority of the modified Bonferroni procedure over Scheffé and Roy-type procedures, where the Bonferroni and Scheffé procedures have been modified to accommodate the logical implications of a false omnibus interaction null hypothesis. An applied example is provided and considerations for applied researchers are offered.

两次世界大战前后的亚欧关系探析

20世纪初叶“亚洲的觉醒”革命风暴作为现代亚洲民族解放运动的序曲 ,对亚欧之间殖民地 (附庸国 )与宗主国的依附关系形成强有力冲击。两次世界大战更是对亚欧关系的演变产生决定性影响。如果说第一次世界大战大大削弱了欧洲对其亚洲殖民地的控制 ,那么第二次世界大战则成为欧洲殖民体系崩溃、亚洲民族新生的历史催化剂 ,使亚欧之间的不平等关系发生了根本性改变。此外二战期间亚欧大陆两端人民在反法西斯斗争中同仇敌忾、互助合作 ,则成为该时期亚欧关系的主要内容。     

词语搭配超常的制约因素考察

在考察语言事实的基础上,指出汉语句法结构中存在传统理解上的词语搭配超常现象,认为这种超常现象的存在,或是语义特征,或是语用频率等因素制约的结果.由此而得出结论:超常只是语面上的,不是实质上的.
