Modern Industrial Economics and Competition Policy: Open Problems and Possible Limits

Naturally, competition policy is based on competition economics made applicable in terms of law and its enforcement. Within the different branches of competition economics, modern industrial economics, or more precisely game-theoretic oligopoly theory, has become the dominating paradigm both in the U.S. (since the 1990s Post-Chicago movement) and in the EU (so-called more economic approach in the 2000s). This contribution reviews the state of the art in antitrust-oriented modern industrial economics and, in particular, critically discusses open questions and possible limits of basing antitrust on modern industrial economics. In doing so, it provides some hints how to escape current enforcement problems in industrial economics-based competition policy on both sides of the Atlantic. In particular, the paper advocates a change of the way modern industrial economics is used in competition policy: instead of more and more case-by-cases analyses, the insights from modern industrial economics should be used to design better competition rules. I like to thank the co-panelists Laurence Idot, Michele Polo and Daniel Rubin-feld as well as all the participants of the conference “Foundations and Limita-tions of an Economic Approach to Competition Law” (Max-Planck-Institute for Intellectual Property, Competition and Tax Law; Munich 12th / 13th March 2009), Arndt Christiansen and Nadine Lindstadt for very valuable and helpful comments.
Meta-Analyses of the 5-HTTLPR Polymorphisms and Post-Traumatic Stress Disorder

Objective To conduct a meta-analysis of all published genetic association studies of 5-HTTLPR polymorphisms performed in PTSD cases Methods Data Sources Potential studies were identified through PubMed/MEDLINE, EMBASE, Web of Science databases (Web of Knowledge, WoK), PsychINFO, PsychArticles and HuGeNet (Human Genome Epidemiology Network) up until December 2011. Study Selection: Published observational studies reporting genotype or allele frequencies of this genetic factor in PTSD cases and in non-PTSD controls were all considered eligible for inclusion in this systematic review. Data Extraction: Two reviewers selected studies for possible inclusion and extracted data independently following a standardized protocol. Statistical analysis: A biallelic and a triallelic meta-analysis, including the total S and S' frequencies, the dominant (S+/LL and S'+/L'L') and the recessive model (SS/L+ and S'S'/L'+), was performed with a random-effect model to calculate the pooled OR and its corresponding 95% CI. Forest plots and Cochran's Q-Statistic and I2 index were calculated to check for heterogeneity. Subgroup analyses and meta-regression were carried out to analyze potential moderators. Publication bias and quality of reporting were also analyzed. Results 13 studies met our inclusion criteria, providing a total sample of 1874 patients with PTSD and 7785 controls in the biallelic meta-analyses and 627 and 3524, respectively, in the triallelic. None of the meta-analyses showed evidence of an association between 5-HTTLPR and PTSD but several characteristics (exposure to the same principal stressor for PTSD cases and controls, adjustment for potential confounding variables, blind assessment, study design, type of PTSD, ethnic distribution and Total Quality Score) influenced the results in subgroup analyses and meta-regression. There was no evidence of potential publication bias. Conclusions Current evidence does not support a direct effect of 5-HTTLPR polymorphisms on PTSD. Further analyses of gene-environment interactions, epigenetic modulation and new studies with large samples and/or meta-analyses are required.
The visibility of the Galactic bulge in optical surveys. Application to the Gaia mission

The bulge is a region of the Galaxy which is of tremendous interest for understanding Galaxy formation. However, measuring photometry and kinematics in it raises several inherent issues, like high extinction in the visible and severe crowding. Here we attempt to estimate the problem of the visibility of the bulge at optical wavelengths, where large CCD mosaics allow to easily cover wide regions from the ground, and where future astrometric missions are planned. Assuming the Besancon Galaxy model and high resolution extinction maps, we estimate the stellar density as a function of longitude, latitude and apparent magnitude and we deduce the possibility of reaching and measuring bulge stars. The method is applied to three Gaia instruments, the BBP and MBP photometers, and the RVS spectrograph. We conclude that, while in the BBP most of the bulge will be accessible, in the MBP there will be a small but significant number of regions where bulge stars will be detected and accurately measured in crowded fields. Assuming that the RVS spectra may be extracted in moderately crowded fields, the bulge will be accessible in most regions apart from the strongly absorbed inner plane regions, because of high extinction, and in low extinction windows like the Baades's window where the crowding is too severe.
Evaluating the Effectiveness of Cryopreserved Acellular Dermal Matrix in Immediate Expander-Based Breast Reconstruction: A Comparison Study

Background CGCryoDerm was first introduced in 2010 and offers a different matrix preservation processes for freezing without drying preparation. From a theoretical perspective, CGCryoDerm has a more preserved dermal structure and more abundant growth factors for angiogenesis and recellularization. In the current study, the authors performed a retrospective study to evaluate freezing- and freeze-drying-processed acellular dermal matrix (ADM) to determine whether any differences were present in an early complication profile. Methods Patients who underwent ADM-assisted tissue expander placement for two stage breast reconstruction between January of 2013 and March of 2014 were retrospectively reviewed and divided into two groups based on the types of ADM-assisted expander reconstruction (CGDerm vs. CGCryoDerm). Complications were divided into four main categories and recorded as follows: seroma, hematoma, infection, and mastectomy skin flap necrosis. Results In a total of 82 consecutive patients, the CGCryoDerm group had lower rates of seroma when compared to the CGDerm group without statistical significance (3.0% vs. 10.2%, P=0.221), respectively. Other complications were similar in both groups. Reconstructions with CGCryoDerm were found to have a significantly longer period of drainage when compared to reconstructions with CGDerm (11.91 days vs. 10.41 days, P=0.043). Conclusions Preliminary findings indicate no significant differences in early complications between implant/expander-based reconstructions using CGCryoderm and those using CGDerm.
The Effects of Word Prediction on Communication Rate for AAC

Individuals using an Augmentative and Alternative Communication (AAC) device communicate at less than 10% of the speed of "traditional" speech, creating a large communication gap. In this user study, we compare the communication rate of pseudo-impaired individuals using two different word prediction algorithms and a system without word prediction. Our results show that word prediction can increase AAC communication rate and that more accurate predictions significantly improve communication rate.
Self-Organized Segregation within an Evolving Population

An evolving population, in which individual members (``agents'') adapt their behavior according to past experience, is of central importance to many disciplines. Because of their limited knowledge and capabilities, agents are forced to make decisions based on inductive, rather than deductive, thinking. We show that a population of competing agents with similar capabilities and knowledge will tend to self-segregate into opposing groups characterized by extreme behavior. Cautious agents perform poorly and tend to become rare.
A high-performance data path for synthesizing DSP kernels

A high-performance data path to implement digital signal processing (DSP) kernels is introduced in this paper. The data path is realized by a flexible computational component (FCC), which is a pure combinational circuit and it can implement any 2 times 2 template (cluster) of primitive resources. Thus, the data path's performance benefits from the intracomponent chaining of operations. Due to the flexible structure of the FCC, the data path is implemented by a small number of such components. This allows for direct connections among FCCs and for exploiting intercomponent chaining, which further improves performance. Due to the universality and flexibility of the FCC, simple and efficient algorithms perform scheduling and binding of the data flow graph (DFG). DSP benchmarks synthesized with the FCC data path method show significant performance improvements when compared with template-based data path designs. Detailed results on execution time, FCC utilization, and area are presented
A contextual study of female-leader role stereotypes in the hotel sector

Abstract Guided by the role congruity theory (RCT), this paper examines the mismatch in female-leader role stereotypes and how this mismatch may lead to prejudicial evaluations against female leaders. It also tests how gender equality practices and leadership development programmes (LDPs) may mitigate prejudicial evaluations against female leaders. Following a quantitative approach, this study uses a paired sample t-test and linear approach (i.e. multiple regression) to model the relationships and test the hypotheses formulated. Drawing on a survey of 392 employees working in 4- and 5-star hotels in Jordan, the study shows that employees stereotype successful leaders to be more masculine than feminine while they attribute both feminine and masculine stereotypes to women. There is, thus, an element of congruity in female-leader role stereotypes which reduces prejudicial evaluations against female leaders. Moreover, the results indicate that gender equality practices and LDPs significantly enhance the emergence and effectiveness of women leaders. The importance of this study derives from extending the RCT through a contextual investigation in the hotel sector in Jordan. This was done by considering two additional constructs, i.e. gender equality practices and LDPs that mitigate prejudice against female leaders.
Detection of Large Numbers of Novel Sequences in the Metatranscriptomes of Complex Marine Microbial Communities

Background Sequencing the expressed genetic information of an ecosystem (metatranscriptome) can provide information about the response of organisms to varying environmental conditions. Until recently, metatranscriptomics has been limited to microarray technology and random cloning methodologies. The application of high-throughput sequencing technology is now enabling access to both known and previously unknown transcripts in natural communities. Methodology/Principal Findings We present a study of a complex marine metatranscriptome obtained from random whole-community mRNA using the GS-FLX Pyrosequencing technology. Eight samples, four DNA and four mRNA, were processed from two time points in a controlled coastal ocean mesocosm study (Bergen, Norway) involving an induced phytoplankton bloom producing a total of 323,161,989 base pairs. Our study confirms the finding of the first published metatranscriptomic studies of marine and soil environments that metatranscriptomics targets highly expressed sequences which are frequently novel. Our alternative methodology increases the range of experimental options available for conducting such studies and is characterized by an exceptional enrichment of mRNA (99.92%) versus ribosomal RNA. Analysis of corresponding metagenomes confirms much higher levels of assembly in the metatranscriptomic samples and a far higher yield of large gene families with >100 members, ∼91% of which were novel. Conclusions/Significance This study provides further evidence that metatranscriptomic studies of natural microbial communities are not only feasible, but when paired with metagenomic data sets, offer an unprecedented opportunity to explore both structure and function of microbial communities – if we can overcome the challenges of elucidating the functions of so many never-seen-before gene families.
Low-Quality Video Face Recognition with Deep Networks and Polygonal Chain Distance

Face recognition under surveillance circumstances still poses a significant problem due to low data quality. Nevertheless, automatic analysis is highly desired for criminal investigations due to the growing amount of security cameras worldwide. We suggest a face recognition system addressing the typical issues such as motion blur, noise or compression artifacts to improve low-quality recognition rates. A low-resolution adapted residual neural net serves as face image descriptor. It is trained by quality adjusted public training data generated by data augmentation strategies such as motion blurring or adding compression artifacts. To further reduce noise effects, a noise resistant manifold-based face track descriptor using a polygonal chain is proposed. This leads to a performance improvement on in-the-wild surveillance data compared to conventional local feature approaches or the state-of-the-art high-resolution VGG-Face network.
Cancer Management and Research Dovepress a Profile of Enzalutamide for the Treatment of Advanced Castration Resistant Prostate Cancer

Recent advances in understanding the mechanisms underlying the development and progression of castration resistant prostate cancer from androgen-sensitive prostate cancer have provided new avenues exploring efficacious therapies in a disease which is the second leading cause of cancer deaths among men in the western world. In the evolution of second generation anti-androgens, enzalutamide, a novel androgen-receptor signaling inhibitor, has emerged targeting multiple steps within the androgenic stimulation pathway. This review discusses what is currently known of the mechanisms surrounding castration resistant prostate cancer development and the current human clinical trials to determine whether enzalutamide presents a new hope for men with advanced prostate cancer. The issues of therapy resistance, withdrawal effects and cross-resistance are briefly touched upon.
Air pollution and daily hospital admissions in metropolitan Los Angeles.

We used daily time-series analysis to evaluate associations between ambient carbon monoxide, nitrogen dioxide, particulate matter [less than and equal to] 10 microm in aerodynamic diameter (PM(10)), or ozone concentrations, and hospital admissions for cardiopulmonary illnesses in metropolitan Los Angeles during 1992-1995. We performed Poisson regressions for the entire patient population and for subgroups defined by season, region, or personal characteristics, allowing for effects of temporal variation, weather, and autocorrelation. CO showed the most consistently significant (p<0.05) relationships to cardiovascular admissions. A wintertime 25th-75th percentile increase in CO (1.1-2.2 ppm) predicted an increase of 4% in cardiovascular admissions. NO(2), and, to a lesser extent, PM(10) tracked CO and showed similar associations with cardiovascular disease, but O(3) was negatively or nonsignificantly associated. No significant demographic differences were found, although increased cardiovascular effects were suggested in diabetics, in whites and blacks (relative to Hispanics and Asians), and in persons older than 65 years of age. Pulmonary disease admissions associated more with NO(2) and PM(10) than with CO. Pulmonary effects were generally smaller than cardiovascular effects and were more sensitive to the choice of model. We conclude that in Los Angeles, atmospheric stagnation with high primary (CO/NO(2)/PM(10)) pollution, most common in autumn/winter, increases the risk of hospitalization for cardiopulmonary illness. Summer photochemical pollution (high O(3)) apparently presents less risk. ImagesFigure 1Figure 2
In vivo growth factor expansion of endogenous subependymal neural precursor cell populations in the adult mouse brain

The lateral ventricle subependyma in the adult mammalian forebrain contains both neural stem and progenitor cells. This study describes the in situ modulation of these subependymal neural precursor populations after intraventricular administration of exogenous growth factors. In vivo infusion of epidermal growth factor (EGF) into adult mouse forebrain for 6 consecutive days resulted in a dramatic increase in the proliferation and total number of subependymal cells and induced their migration away from the lateral ventricle walls into adjacent parenchyma. Immediately after EGF infusion, immunohistochemical characterization of the EGF-expanded cell population demonstrated that >95% of these cells were EGF receptor- and nestin-positive, whereas only 0.9% and 0.2% labeled for astrocytic and neuronal markers, respectively. Seven weeks after EGF withdrawal, 25% of the cells induced to proliferate after 6d of EGF were still detectable; 28% of these cells had differentiated into new astrocytes and 3% into new neurons in the cortex, striatum, and septum. Newly generated oligodendrocytes were also observed. These in vivo results (1) confirm the existence of EGF-responsive subependymal neural precursor cells in the adult mouse forebrain and (2) suggest that EGF acts directly as a proliferation, survival, and migration factor for subependymal precursor cells to expand these populations and promote the movement of these cells into normal brain parenchyma. Thus, in situ modulation of endogenous forebrain precursor cells represents a novel model for studying neural development in the adult mammalian brain and may provide insights that will achieve adult replacement of neurons and glia lost to disease or trauma.
Jejunal intussusception caused by a huge Vanek's tumor: a case report

Inflammatory fibroid polyp (known also as Vanek's tumor) is a type of localized, non-neoplastic inflammatory pseudotumor or inflammatory myofibroblastic tumor that occurs most commonly in the stomach but also in the small and large bowel. It is a documented cause of intussusception in adults. We report a case of a 40-year-old woman who presented with severe, postprandial abdominal pain followed by projectile vomiting over a period of three days. Ultrasonography demonstrated a solid and echogenic mass surrounded by the typical mural layers of an invaginated jejunum. She underwent urgent laparotomy and resection of an 18 cm tumor from the distal jejunum. The immuno-histopathological diagnosis after segmental jejunal resection was a jejunal inflammatory fibroid polyp. Although inflammatory fibroid polyps are seen very rarely in adults, they are among the probable diagnoses that should be considered in obstructive tumors of the small bowel causing intussusceptions.
Emergency Department Nurses' Experiences of Violent Acts in the Workplace

EMERGENCY DEPARTMENT NURSE’S EXPERENCIES OF VIOLENT ACTS IN THE WORKPLACE May 2009 PAUL MACKINNON, BS. , UNIVERSITY OF MASSACHUSETTS AMHERST MS., UNIVERSITY OF MASSACHUSETTS AMHERST PhD. , UNIVERSITY OF MASSACHUSETTS WORCESTER Directed by Dr. Carol Bova Emergency department nurses are at high risk for violence in the workplace (Keely, 2002; Fernandez et al., 1998; Nachreiner et al., 2005; Mayer et al., 1999). It is estimated that between 52% and 82% of emergency nurses will experience physical violence and 100% of emergency department nurses will experience non-physical violence in their careers. Despite this fact, there are limited studies examining workplace violence among this vulnerable group (Fernandez et al., 1998; Levin et al., 1998). Therefore, the purpose of this qualitative descriptive study was to examine the experiences of emergency department nurses with workplace violence. Levin et al.’s (2003) Ecological Occupational Model (EOHM) was used to guide this study. Four focus groups were conducted with 27 nurses who represented different types of emergency departments (rural community facility to large urban Level 1 trauma center). Results of the study suggested that the majority of participants (96%) experienced some form of work-related violence and 75% had attended at least one violence education class. The major themes of frustration and powerlessness emerged from the data. Sub themes included professional conflict while caring for violent
Broad-Coverage Parsing Using Human-Like Memory Constraints

Abstract Human syntactic processing shows many signs of taking place within a general-purpose short-term memory. But this kind of memory is known to have a severely constrained storage capacity—possibly constrained to as few as three or four distinct elements. This article describes a model of syntactic processing that operates successfully within these severe constraints, by recognizing constituents in a right-corner transformed representation (a variant of left-corner parsing) and mapping this representation to random variables in a Hierarchic Hidden Markov Model, a factored time-series model which probabilistically models the contents of a bounded memory store over time. Evaluations of the coverage of this model on a large syntactically annotated corpus of English sentences, and the accuracy of a a bounded-memory parsing strategy based on this model, suggest this model may be cognitively plausible.
European Conference on Information Systems ( ECIS ) 2005 Understanding Performance Measurement and Control in Third Party Logistics

Each individual planning process starts with clear objectives. These objectives specify the goals for the planning process, which is assigning tasks to resources at a certain point in time. Planning systems, whether manual or computerized, should utilize those objectives in their planning. In order to gain insight in the specific planning objectives for the Logistical Service Providers (LSPs) domain, we study the Key Performance Indicators (KPIs) related to this field. Typically, KPIs are used in a postante context: to evaluate the past performance of a company. We reason that KPIs could be utilized differently as well: if one knows what counts afterwards, it would be logical to anticipate this in the planning phase. This paper thus focuses on the performance parameters and objectives that play a role in the logistical planning process. In order to gain insight in the factors that should play a role when designing a new software system for planning and control of LSP operations. In this paper we present an extensive literature survey we performed, and introduce a framework that is capable of capturing the dynamics of competing KPIs, while positioning them in the practical context of an LSP. We conclude with a first validation of the framework and a roadmap for our future work, with the design of a software agentbased planning system for (road-) logistics as an intended final result.
The cosmological evolution of the QSO luminosity density and of the star formation rate

We demonstrate that the evolution of the QSO luminosity density with epoch displays a striking similarity to the cosmological evolution of the field galaxy star formation rate, recently derived from a number of independent surveys. The QSO luminosity density at 2800 A is approximately one-fortieth that implied by the star formation rate in galaxies throughout the past 11 Gyr (z < 4). This similarity suggests that a substantial fraction of the QSO luminosity may be closely linked to the star formation process and its evolution with cosmic time.
Effect of Activation Parameters on Conversion in Clay-Catalyzed Esterification of Acetic Acid

0.5M with its highest conversion of 74.29% also at 200 o C. This makes 0.5M the better option from economic point of view. Longer activation time gave higher conversion during the medium temperature activation but at high activation temperature, conversion decreased with longer activation duration. From the statistical analysis using ANOVA, the strength of the activating acid had the highest significance while the effects activation temperature and duration were less significant.
