Online Resumes: Optimizing Design to Service Recruiters

Despite the increasing number of publications in e-Recruiting, there is still scant research on the specific requirements of online resume fields, in particular from the recruiters’ perspective. In this paper, the fields for resume forms are investigated by analyzing literature, interviewing recruiters and systematically categorizing and content-analyzing the resume fields of the 40 largest Dutch e- Recruiting sites. The findings reflect the main categories currently used in online resume forms: current career status, desired job, education, work experience, extracurricular activities, skills and personal and contact information. These identified online resume fields are discussed in light of prior resume design literature and compared with resume requirements derived from interviewing recruiters. Recommendations for resume design theory and practice are proposed

Bootstrapping the economy -- a non-parametric method of generating consistent future scenarios

The fortune and the risk of a business venture depends on the future course of the economy. There is a strong demand for economic forecasts and scenarios that can be applied to planning and modeling. While there is an ongoing debate on modeling economic scenarios, the bootstrapping (or resampling) approach presented here has several advantages. As a non-parametric method, it directly relies on past market behaviors rather than debatable assumptions on models and parameters. Simultaneous dependencies between economic variables are automatically captured. Some aspects of the bootstrapping method require additional modeling: choice and ransformation of the economic variables, arbitrage-free consistency, heavy tails of distributions, serial dependence, trends and mean reversion. Results of a complete economic scenario generator are presented, tested and discussed.economic scenario generator (ESG); asset-liability management (ALM); bootstrapping; resampling; simulation; Monte-Carlo simulation; non-parametric model; yield curve model

Electronic fraud detection in the U.S. Medicaid Healthcare Program: lessons learned from other industries

It is estimated that between $600 and$850 billion annually is lost to fraud, waste, and abuse in the US healthcare system,with $125 to$175 billion of this due to fraudulent activity (Kelley 2009). Medicaid, a state-run, federally-matchedgovernment program which accounts for roughly one-quarter of all healthcare expenses in the US, has been particularlysusceptible targets for fraud in recent years. With escalating overall healthcare costs, payers, especially government-runprograms, must seek savings throughout the system to maintain reasonable quality of care standards. As such, the need foreffective fraud detection and prevention is critical. Electronic fraud detection systems are widely used in the insurance,telecommunications, and financial sectors. What lessons can be learned from these efforts and applied to improve frauddetection in the Medicaid health care program? In this paper, we conduct a systematic literature study to analyze theapplicability of existing electronic fraud detection techniques in similar industries to the US Medicaid program

A Typology of Design Knowledge: A Theoretical Framework

This paper is a theoretical approach to structure design-specific knowledge into a framework, which can be used within the context of organizational and societal development. We conducted an extensive literature review about existing definitions of design knowledge, and knowledge in general. Based on this, we developed a typology, which consists of four different types of design knowledge and three interjacent transitions. According to our proposed framework, design knowledge can be represented in physical artifacts, as tacit gut feeling, as codified knowledge, or as scientific theories. To illustrate further we present examples for each knowledge type and transition and we suggest prototypical approaches for transferring these types of design knowledge in the context of design education. We believe this paper contributes to a better understanding of design knowledge, and our suggested framework might serve as a foundation for further design research, and for developing ITsystems to support design processes

Understanding Artifact Knowledge in Design Science: Prototypes and Products as Knowledge Repositories

This article analyzes the role of artifacts in Information Systems regarding their capability to store and transfer designknowledge and to support the researcher-practitioner collaboration. A definition for design artifacts and their characteristicsis presented that distinguishes between prototypes and products. Based on three examples for artifacts from the field ofInformation Systems, deficits concerning the accessibility of artifacts are identified, as well as problems of unintentionalembedding of knowledge into artifacts—both results in a \u27design science dilemma\u27. A strategy of \u27open artifacts\u27 is suggested,since this might support the collaboration between authors of artifacts (practitioners) and researchers who may want to extractand analyze the embedded knowledge. The work in this paper contributes to a better understanding of knowledge transfermechanisms in design science and can be used as a foundation for further research in the development of artifact-basedknowledge transfer and re-engineering

Transverse Velocity Dependence of the Proton-Antiproton Ratio as a Signature of the QCD Critical Endpoint

The presence of a critical point in the QCD phase diagram can deform the trajectories describing the evolution of the expanding fireball in the $\mu_B-T$ phase diagram. If the average emission time of hadrons is a function of transverse velocity, as microscopic simulations of the hadronic freeze-out dynamics suggest, the deformation of the hydrodynamic trajectories will change the transverse velocity ($\beta_{\rm T}$) dependence of the proton-antiproton ratio when the fireball passes in the vicinity of the critical point. An unusual $\beta_{\rm T}$-dependence of the $\bar{p}/p$ ratio in a narrow beam energy window would thus signal the presence of the critical point.Comment: Final version accepted for publicatio

Crowdsourcing with Semantic Differentials: A Game to Investigate the Meaning of Form

This paper presents a tool to collect empirical data about the collaborative meaning of form. We developed an online crowdscouring game, in which two users rate randomly assigned three-dimensional shapes. The more similar the ratings are, the more points both players get. This crowdsourcing method allows identifying what certain shapes mean to people. This paper is a contribution on two levels: First, the game presents a particular research method—an experimental survey using semantic differentials—, which adds a motivational benefit for the participants: It is fun to play. Also, it involves a quality control mechanism through the pairing of two participants who rate the same image and therefore act as verification. Second, the semantic collection of forms might help designers to better control the connotative meanings embedded in their designs. This paper is focused on introducing the game; the analysis of the data will be covered in further research

Synergistic interaction of hTGF-β3 with hBMP-6 promotes articular cartilage formation in chitosan scaffolds with hADSCs: implications for regenerative medicine

BACKGROUND Human TGF-β3 has been used in many studies to induce genes coding for typical cartilage matrix components and accelerate chondrogenic differentiation, making it the standard constituent in most cultivation media used for the assessment of chondrogenesis associated with various stem cell types on carrier matrices. However, in vivo data suggests that TGF-β3 and its other isoforms also induce endochondral and intramembranous osteogenesis in non-primate species to other mammals. Based on previously demonstrated improved articular cartilage induction by a using hTGF-β3 and hBMP-6 together on hADSC cultures and the interaction of TGF- β with matrix in vivo, the present study investigates the interaction of a chitosan scaffold as polyanionic polysaccharide with both growth factors. The study analyzes the difference between chondrogenic differentiation that leads to stable hyaline cartilage and the endochondral ossification route that ends in hypertrophy by extending the usual panel of investigated gene expression and stringent employment of quantitative PCR. RESULTS By assessing the viability, proliferation, matrix formation and gene expression patterns it is shown that hTGF-β3 + hBMP-6 promotes improved hyaline articular cartilage formation in a chitosan scaffold in which ACAN with Col2A1 and not Col1A1 nor Col10A1 where highly expressed both at a transcriptional and translational level. Inversely, hTGF-β3 alone tended towards endochondral bone formation showing according protein and gene expression patterns. CONCLUSION These findings demonstrate that clinical therapies should consider using hTGF-β3 + hBMP-6 in articular cartilage regeneration therapies as the synergistic interaction of these morphogens seems to ensure and maintain proper hyaline articular cartilage matrix formation counteracting degeneration to fibrous tissue or ossification. These effects are produced by interaction of the growth factors with the polysaccharide matrix
