When the job you were hired for changes: Realigning job descriptions with job priorities

In this poster, two librarians at two different institutions will present results of job audits they completed, based on the Academic Library Value: The Impact Starter Kit by Megan Oakleaf (2017). Collaborating across institutions, these early-career librarians were able to work through the job audit process together, and engage in open discussions that might have been impossible with a different colleague at their home institutions. These librarians each decided to complete a job audit because they saw a need to recast their job descriptions. Each holds a position that was newly created at the time they were hired, in order to support their colleges’ rapid growth in online, distance, and hybrid education. At the same time, these librarians were new to librarianship, and faced similar challenges. First of these challenges was learning a new job in an environment where each librarian knew their position was needed, but there were no signposts. As they settled into their roles, and continued to grow their work, they began to realize that much of their jobs had morphed due to change in both of their home institutions. Their job descriptions no longer accurately represented their actual day-to-day work, and they started looking for a way to reconcile this disparity. Poster attendees will not only see the results of these two job audits, but have the chance to hear from these librarians about their experiences. Attendees will learn about changes have made at their respective institutions regarding their job descriptions. Poster attendees will be able to understand the job audit process in order to be able to do it themselves. This poster will provide a starting point for conversations about realigning job priorities to your institution, proving your value, and reinvigorating the love you have for your job

Building women leaders: Recasting early career leadership

Are you a new librarian facing leadership challenges? Do you identify as a woman? Are you wondering how you can lead with no official authority? Most library workers across the U.S. are women, yet women librarians still face structural and institutional barriers to leading. Join a discussion about women librarians and the obstacles they face while learning how to be a leader. Learn from other early-career, women librarians who have been working to build their leadership capacity. We invite women from a variety of contexts, backgrounds, and identities to take part in this conversation

Theoretical model for mass transport and adsorption of gases in porous solids based on the frequency response method

Detailed knowledge of mass transport and adsorption is one of the key factors in the development of novel high-performance porous materials for a wide range of technical applications. In the course of an optimization process, a quick conclusion on the properties of the pore system and its accessibility for certain sample molecules is crucial. On the other hand, predictions about the pore system can save steps in material development

Towards simultaneous meta-modeling for both the output and input spaces in the context of design shape optimization using asynchronous high-performance computing

ECCOMAS PhD Olympiads 2013International audience. In this paper, we propose a simultaneous meta-modeling protocol for both input and output spaces. We perform a reparametrization of the input space using constrained shape interpolation by introducing the concept of an α-manifold of admissible meshed shapes. The output space is reduced using constrained Proper Orthogonal Decomposition. By simultaneously using meta-modeling for both spaces, we facilitate interactive design space exploration for the purpose of design. The proposed approach is applied to several industrial problems

Automatic Domain Adaptation Outperforms Manual Domain Adaptation for Predicting Financial Outcomes

In this paper, we automatically create senti- ment dictionaries for predicting financial out- comes. We compare three approaches: (i) manual adaptation of the domain-general dic- tionary H4N, (ii) automatic adaptation of H4N and (iii) a combination consisting of first man- ual, then automatic adaptation. In our experi- ments, we demonstrate that the automatically adapted sentiment dictionary outperforms the previous state of the art in predicting the finan- cial outcomes excess return and volatility. In particular, automatic adaptation performs bet- ter than manual adaptation. In our analysis, we find that annotation based on an expert’s a priori belief about a word’s meaning can be incorrect – annotation should be performed based on the word’s contexts in the target do- main instead

Transport of isopropanol in H-ZSM5 by impedance spectroscopy

Gas diffusion mechanisms and diffusion coefficients in microkinetic system of solid materials characterize the different performance of chemical and transport processes. These factors should be evaluated with respect to the range of diffusion coefficients based on the number of experimental methods. Here, impedance spectroscopy which is a powerful tool for understanding transport phenomena of gases in nanostructured porous solids is used. In this work, we developed a new approach to compare and evaluate diffusion coefficients of isopropanol in the zeolite H-ZSM5. Furthermore, FTIR spectroscopy was used to study the adsorption of isopropanol in H-ZSM5 at different temperatures to support the interpretation of diffusion regimes. The combination of EIS with FTIR enables to illustrate preferred interaction sites and their influence on transport processes. The activation energy for transport of molecules in the channels is also calculated. Results are compared to literature data and suggest improved applications of EIS to characterize transport processes

Energy scaling by stacking of ultrashort pulses in a passive enhancement cavity

New applications of ultrafast laser systems require parameters, which are out of reach for classical single amplifier channels. Coherent pulse combining can help to circumvent the limitations, which state-of-the-art laser systems are facing. For that purpose, passive optical resonators, so-called enhancement cavities, can be used to stack laser pulses, thus, drastically increasing their pulse energy. Extracting such an enhanced pulse from the cavity, could lead to a set of laser parameters, not accessible to other amplifier technologies. Enhancement cavities running at 80 MHz or above have been used as pulse stacking devices before, employing acousto-optic-modulators (AOM) as switches to extract the stacked energy. However, the nonlinear phases, as introduced by self-phase-modulation in the AOM, commonly limit the achievable intra-cavity energy of a so-called stack-and-dump cavity. By lengthen such cavities to 10 MHz, the extractable energies from such a device were improved by three orders of magnitude from 200 nJ to 160 J compared to former experiments. While longer cavities could allow for even higher energies, they are difficult to set-up and are often limited by their complexity and stability related issues. This is why, novel switches would have to be introduced, if the potential of stack-and-dump cavities is to be exhausted. A rotating element in the cavity is identified as one possible solution. It circumvents acceleration-related limitations and could allow for fast extraction of the enhanced pulse without disturbing the enhancement process. Possible switches based on rotation include a chopper wheel with mirror-segments attached to its side-facet and a rotating-cavity-caustic. Both have been investigated and identified to be viable solutions
