From Stimulus to System: Using the ARRA to Serve Disadvantaged Jobseekers

This paper explores models and mechanisms for connecting low-skilled jobseekers to ARRA-related job opportunities--including community-benefit agreements, job linkage/first source hiring, and goals and standards for job creation and job quality--and for subsequently engaging jobseekers in further skill-building and educational programs

Video Styles and Learning

With the current prevalence of online and distance learning, videos are becoming a larger part of our education system. It is important that we be able to fully utilize the potential of videos as education tools. Videos make use of more senses than just printed materials, and provide greater flexibility for both teachers and students (Bevan). What qualities make a good educational video? We believe that to be effective at teaching a video needs to be interesting enough to students’ attention and have enough information to be useful. By surveying a number of college students, we were able to support my hypothesis. With this information, we will be able to better select and create instructional videos both in academia and in the world at large

Distributional composition using higher-order dependency vectors

This paper concerns how to apply compositional methods to vectors based on grammatical dependency relation vectors. We demonstrate the potential of a novel approach which uses higher-order grammatical dependency relations as features. We apply the approach to adjective-noun compounds with promising results in the prediction of the vectors for (held-out) observed phrases

Direct Measurement of Vanadium Crossover in an Operating Vanadium Redox Flow Battery

Measurements of Vanadium diffusion coefficients for transport across cation exchange membranes using dialysis cells have been reported in the literature. However, to date direct measurement of crossover coefficients in an operating Vanadium redox flow battery (VRB) cell have not been reported. Results are reported in this paper on experiments utilizing a special VRB cell which allows measurement of Vanadium ion transport across ion exchange membranes with and without the presence of current. The cell utilizes two additional flow regions which collect Vanadium ions which diffuse from the positive and negative half cells. The effects of the magnitude and direction of electrical current on transport can be measured directly with this cell. We observe that transport is greatly enhanced when the direction of the hydrogen ion flux is in the same direction as the density gradient driven vanadium flux and suppressed when the hydrogen ion flux is in the opposite direction. The cell has been used to of investigate the effects on transport of current densities up to 900 mA/cm(2).US Department of Energy ARPA-E program DE-AR00000149Materials Science and Engineerin

Communicating Resilience: A Discursive Leadership Perspective

In this essay we challenge whether current conceptions of optimism, hope, and resilience are complete enough to account for the complexity and nuance of developing and maintaining these in practice. For example, a quick perusal of popular outlets (e.g., Forbes, Harvard Business Review) reveals advice to managers urging them to “be optimistic,” or “be happy” so that these types of emotions or feelings can spread to the workplace. One even finds simple advice and steps to follow on how to foster these types of things in the workplace (McKee; Tjan). We argue that this common perspective focuses narrowly on individuals and does not account for the complexity of resilience. Consequently, it denies the role of context, culture, and interactions as ways people develop shared meaning and reality. To fill this gap in our understanding, we take a social constructionist perspective to understand resilience. In other words, we foreground communication as the primary building block to sharing meaning and creating our worlds. In so doing, we veer away from the traditional focus on the individual and instead emphasise the social and cultural elements that shape how meaning is shared by peoples in various contexts (Fairhurst, Considering Context). Drawing on a communication, discourse-centered perspective we explore hope and optimism as concepts commonly associated with resilience in a work context. At work, leaders play a vital role in communicating ways that foster resilience in the face of organisational issues and events (e.g., environmental crises, downsizing). Following this lead, discursive leadership offers a framework that positions leadership as co-created and as the management of meaning through framing (Fairhurst, Power of Framing). Thus, we propose that a discursive leadership orientation can contribute to the communicative construction of resilience that moves away from individual perspectives to an emphasis on the social. From a discursive perspective, leadership is defined as a process of meaning management; attribution given by followers or observers; process-focused rather than leader-focused; and as shifting and distributed among several organizational members (Fairhurst Power of Framing). By switching from the individual focus and concentrating on social and cultural systems, discursive leadership is able to study concepts related to subjectivity, cultures, and identities as it relates to meaning. Our aim is to offer leaders an alternative perspective on resilience at the individual and group level by explaining how a discursive orientation to leadership can contribute to the communicative construction of resilience. We argue that a social constructionist approach provides a perspective that can unravel the multiple layers that make up hope, optimism, and resilience. We begin with a peek into the social scientific perspective that is so commonplace in media and popular portrayals of these constructs. Then, we explain the social constructionist perspective that grounds our framework, drawing on discursive leadership. Next, we present an alternative model of resilience, one that takes resilience as communicatively constructed and socially created. We believe this more robust perspective can help individuals, groups, and cultures be more resilient in the face of challenges
