报告摘要：In this paper, we provide a novel application of synthetic control methods by offering two major tweaks to the existing methodological framework. We provide the first complete ex-post evaluation of the causal impact of carbon pricing on aviation supply, expressed in terms of airline output (i.e., number of seats supplied at the airline-route level). We exploit the policy change in the European Union Emission Trading System (EU-ETS), the first large greenhouse gas emissions trading scheme in the world. We distinguish between low-cost, regional and full service airlines, short and medium/long-haul routes, routes towards (or from) hub airports versus non hub airports, monopolistic versus non-monopolistic routes. The analysis shows that the EU-ETS does not have a substantial impact on the average aircraft size, while it has caused a reduction of total airline seat capacity and frequency, with the percentage of airline seat capacity reduction reaching above 20% at its peak. The overall effect of the policy has a remarkable impact on low-cost and regional airlines, on short- haul routes, spoke-spoke markets and monopolistic routes. Our results are the first empirical confirmation to the theoretical prediction in the aviation literature that emission charges will reduce flight frequency and increase load factors while having no effect on aircraft size.

报告摘要：

Experienced passage of time, the extent to which employees perceive the passage of work time as being fast or slow, is a fundamental aspect of work experience. We identify two novel temporal work design characteristics that can speed up employees’ experienced passage of time: temporal predictability and task segmentation. Jobs with high temporal predictability do not make employees go through uncertain wait times before embarking on their next task. High task segmentation occurs when a large chunk of work time is segmented by categorically different temporal markers. We tested a model in which temporal predictability and task segmentation affect experienced passage of time, which in turn influences job performance, with five studies: two experiments that established the internal validity of temporal predictability and task segmentation (Studies 1a and 1b), a naturalistic field study in a factory that investigated the natural consequences of distinct temporal work design (Study 2), an organizational field study that constructively replicated the model using a sample of knowledge workers and their supervisors (Study 3), and an online survey in which we connected our model with the broader work design literature (Study 4). Altogether, the studies support a new temporal approach to work design.

报告摘要：

Writing is a complex task that requires training and practice of many techniques, such as organizing ideas logically, constructing sentences and paragraphs coherently, presenting with appropriate tones, formatting in a stylish manner, and executing in an ethical and professional way. Written communication reveals our intelligence of thinking, ability of using words, level of education, and so forth. Good writers are usually creative people with brilliant ideas, which can help capable writers excel in their career development. Writing skills are important to students’ employability and career advancement. This workshop trains students in writing with clarity and conciseness. Course materials will be presented following writing sequence. It begins with preparation and outline, continues with drafting and revision, and ends with formatting and proofreading.
