Abstract： With the rapid development of the economy and society, the critical role of the sustainability of altruism is more salient for organizations and their employees to have a better adaptation and greater prosperity. Although altruistic behaviors are very critical to modern organizations, there are several severe deficiencies in the understanding of the nature of altruistic behaviors and the investigation of its formation mechanism in the current altruism literature. First, researchers have long believed that altruism behaviors are static trait-like behaviors, and behavioral differences mainly exist at the interpersonal level. Therefore, most of the previous research in this area focused on the exploration of interpersonal differences in the static value of altruistic behaviors. This deficiency not only keeps previous research from accurately reflecting the characteristics of long-term trajectories of altruistic behavior but may also cover up the possible outliers in the short-term volatility of altruistic behavior, which may lead to the misjudgment that treating the static value of altruistic behavior as the “ideal” altruistic behavior which is stable and sustainable. Second, the existing investigation of altruistic behavior via a dynamic theoretical lens or using dynamic methods generally lacks systematic integration. A key problem is that, although scholars generally believe that altruistic behaviors have features of both long-term trends and short-term volatility, most of the existing studies were based on narrower research frameworks and independently discussed either short-term volatility or long-term trend of altruistic behavior, respectively. If the above two issues remain unsolved, it will lead to our incomplete understanding of the antecedents and forming mechanism of altruistic behavior. Therefore, based on the model of proactive motivation, this paper attempts to construct a theoretical framework of the sustainability of altruistic behaviors, examining the short-term volatility and long-term trends of altruistic behavior simultaneously, and exploring individual and leadership antecedents and forming mechanisms of the sustainability of altruistic behavior. Specifically, using a mixed-method of longitudinal survey and experience sampling method, this study firstly aims to clarify the nature of the sustainability of altruistic behaviors, to uncover the relationship between the short-term volatility and long-term trend of altruistic behavior, and by which to enrich our understanding of the sustainability of altruistic behavior. Secondly, we aim to explore how employee antecedents (belief in a justice world and perceived overqualification) and leader antecedents (ethical leadership and abusive supervision) impact the goal-setting (short-term volatility) and goal-striving (long-term trend) of altruistic behavior via “energized to” path (state gratitude, psychological entitlement, and heroism), “reason to” path (organizational concern and impression management motives), and “can do” path (reciprocal cognition and career adaptability). To sum up, based on the model of proactive motivation, this paper facilitates the literature on altruistic behavior by filling an important research gap regarding the sustainability of altruistic behavior and advancing the knowledge on antecedents and forming mechanisms of the sustainability of altruistic behavior. Moreover, the findings of the current research would also provide practical suggestions for the construction of sustainable reciprocal teams and organizations.

Abstract：
With the rapid development of the economy and society, the critical role of the sustainability of altruism is more salient for organizations and their employees to have a better adaptation and greater prosperity. Although recent studies have found that altruistic behavior is dynamic in nature, there are severe deficiencies in theoretical frameworks and methods of these studies. They were unable to obtain a comprehensive picture of the dynamic sustainability of altruistic behavior, not to mention its antecedents and consequences. Therefore, the current study aims to explore the antecedents of sustainability of altruistic behavior and its forming mechanism. By doing so, the current research could facilitate our understanding of the nature of altruism and guide the practice of constructing sustainable mutually beneficial teams and organizations.

Abstract： 沉积物粒度特征是分析粒度组成演变过程、判别沉积环境的重要参考。对新疆图开沙漠灌 丛沙堆及抛物线形沙丘表层沉积物粒级级配、粒度参数进行了系统分析，并利用 Sahu 经验模型判 断了沉积环境。结果表明：（1）灌丛沙堆及抛物线形沙丘表层沉积物偏粗，主要由极细砂、细砂、中 砂、粗砂组成。（2）各粒级在不同地貌部位分布存在差异，表层沉积物粒度由迎风坡向背风坡沙粒 趋向于细化，由坡底到坡顶沙粒趋于细化。（3）不同地貌部位之间粒度参数呈现不同变化趋势，且粒度参数之间有相关性，平均粒径与分选系数、偏度、峰态之间的相关性不大，而分选系数、偏度、 峰态之间呈现显著的相关性。（4）沉积物形成环境主要为风成环境及浊流环境。

Abstract：限制性核酸内切酶是DNA重组的重要分子生物学工具。由于其本身对DNA有切割作用导致其重组表达在技术上十分困难，产率低、提纯程序复杂。而商业化生产所采用的利用专一型甲基化酶保护宿主DNA的限制酶表达技术流程繁琐、实用性有限。本研究为表达Not I限制酶，采用来源于Spiroplasma sp. MQ1的DNA甲基化酶M.Sss I特异性甲基化CpG序列，甲基化后的DNA会免受识别位点中包含CpG序列的限制酶Not I的切割。将甲基化酶M.Sss I导入大肠杆菌表达宿主ER2566中后，M.Sss I基因在宿主中持续表达并甲基化宿主DNA成CpG甲基化样式；利用此表达体系制备限制性内切酶Not I获得成功。并借助引入纯化标签经过简便的Ni亲和层析和阴离子交换层析2步层析洗脱纯化，制备了高活力高纯度的重组限制酶Not I。此表达体系可应用于一系列识别位点中包含CpG序列的限制酶的表达。
