D2‐resected stage IIIc gastric cancer patients benefit from adjuvant chemoradiotherapy

Although adjuvant chemoradiotherapy has been an important part in the treatment of gastric cancer, whether or not adjuvant radiation can benefit patients undergoing resection with D2 lymph node dissection remains controversial. This retrospective study aimed to evaluate the role of adjuvant chemoradiotherapy on patients with D2‐resected gastric cancer. A total of 337 patients with resected gastric cancer treated at Zhongnan Hospital of Wuhan University from 2004 to 2012 were retrospectively analyzed. Eligible patients were divided into the adjuvant chemoradiotherapy group (CRT; n = 124) and the adjuvant chemotherapy group (CT; n = 213). The primary endpoints were disease‐free survival (DFS) and overall survival (OS), with toxicity as the secondary endpoint. A subgroup analysis was performed based on clinical staging. The two groups were comparable in baseline characteristic, except for the number of lymph nodes dissected. The median OSs in the CRT and CT groups were 51.0 months and 48.6 months, respectively (P = 0.251), and the median DFSs were 40.7 months and 31.2 months, respectively (P = 0.112). Subgroup analysis revealed that the median OSs in patients at stage IIIc in the CRT group and CT group were 29.0 and 23.0 months, respectively (P = 0.049), and those of the median DFSs were 21.2 and 15.1 months, respectively (P = 0.015). There was no significant difference in main adverse events between two groups. Collectively, adjuvant chemoradiotherapy in gastric cancer patients with D2 resection was well tolerated. For Stage IIIc patients, the addition of adjuvant chemoradiotherapy was associated with a significant benefit in both OS and DFS.
Strong priming of T cells adoptively transferred into scid mice

We have examined the requirements for activating unprimed T cells in vivo by transferring T cells into scid mice, which lack mature B and T cells. Purified adult thymocytes and a protein antigen, keyhole limpet hemocyanin (KLH), were injected into scid mice. scid mice injected with T cells and KLH developed cellular lymph nodes containing CD4+ and CD8+ T cells. Cells recovered from the lymph nodes of injected scid mice proliferated and secreted interleukin 2 in response to KLH in vitro. The results indicate that T cells can be primed to KLH in the scid mouse in the absence of B cells.
Does municipalization affect the local unemployment rate

Towns and cities across the United States are considering the municipalization of their electric utilities as an alternative to investor-owned or deregulated utilities. This paper studies the effect of municipalization on local economies, specifically the changes in the unemployment rate in a county that experienced a recent municipalization. A differencein-differences model analyzes the possible effects of municipalization on unemployment rates between county-pairs given underlying economic trends. The results demonstrate that municipalization may reduce a county’s unemployment rate by 6.9% when compared to a county that did not experience a recent municipalization. However, there is evidence suggesting that those counties that have had a recent municipalization are in some way different from those that have not.
Coherent vs. incoherent pairing in 2D systems near magnetic instability

We study the superconductivity in 2D fermionic systems near antiferromagnetic instability, assuming that the pairing is mediated by spin fluctuations. This pairing involves fully incoherent fermions and diffusive spin excitations. We show that the competition between fermionic incoherence and strong pairing interaction yields the pairing instability temperature Tins which increases and saturates as the magnetic correlation length ξ → ∞. We argue that in this quantum-critical regime the pairing problem is qualitatively different from the BCS one.
Management of Global Virtual Project Teams between Europe and East Asia. In cooperation with Infineon Technologies.

Since research about global work is less focused on certain regions, this thesis emphasizes the working in a global virtual project team spread over different locations in Europe and Asia. Based on a literature research, eight challenges of global virtual project teams are identified which result from the cultural and geographical distance that global virtual projects encounter. In addition to that, the scholars’ recommended actions to mitigate these challenges are summarized. In the practical section, a global virtual project team from Infineon Technologies and its existing cultural and geographical distances are analyzed. The perceived challenges are identified based on ten interviews with team members from different locations. Two of the scholar’s challenges are supported: the project team encounters a ‘Lack of Cultural Awareness’ as well as a ‘Lack of Language Knowhow’. As a result, it is discussed how these challenges can be mitigated.
Maximum Weighted Induced Bipartite Subgraphs and Acyclic Subgraphs of Planar Cubic Graphs

We study the maximum node-weighted induced bipartite subgraph problem in planar graphs with maximum degree three. We show that this is polynomially solvable. It was shown in [6] that it is NP-complete if the maximum degree is four. We extend these ideas to the problem of balancing signed graphs.
Social cognitive drivers of farmer learning behaviour in the student-to-farmer university outreach in Uganda

Globally, universities are repositioning themselves for community outreach although with difficulty in responding to the unpredictable social features of host communities. Accordingly, this study aims to assess the role of social cognitive factors in farmer learning behaviour during university outreach. Structural equation modelling was conducted on the data obtained from a sample of 283 host participants of the student outreach programme of Gulu University, Uganda. The results indicate that social outcome expectations (β = 0.227, t = 1.978, P < 0.05), social influence (β = .372, t = 4.448, P < 0.01) and farmers’ formation of intentions (β = .214, t = 3.254, P < 0.01) significantly predict farmer learning behaviour. It is also established that social influence combine with formation of intentions to mediate social outcome expectations in predicting farmer learning behaviour. We highlight that tapping into the social setting of host farmers is critical for the success of university outreach in the sense that it generates the social reinforcements for effective farmer participation and learning. We recommend that the managers of university outreach programmes should devote efforts to prepare students to be sensitive to the concerns and needs of the community as a whole rather than just the host farmers.
The z ~ 4 Lyman Break Galaxies: Colors and Theoretical Predictions

We investigate several fundamental properties of z ~ 4 Lyman break galaxies by comparing observations with the predictions of a semianalytic model based on the cold dark matter theory of hierarchical structure formation. We use a sample of B435-dropouts from the Great Observatories Origins Deep Survey and complement the Advanced Camera for Surveys optical B435, V606, i775, and z850 data with the Very Large Telescope Infrared Spectrometer and Array Camera J, H, and Ks observations. We extract B435-dropouts from our semianalytic mock catalog using the same color criteria and magnitude limits that were applied to the observed sample. We find that the i775-Ks colors of the model-derived and observed B435-dropouts are in good agreement. However, we find that the i775-z850 colors differ significantly, indicating perhaps that either too little dust or an incorrect extinction curve has been used. Motivated by the reasonably good agreement between the model and observed data, we present predictions for the stellar masses, star formation rates, and ages for the z ~ 4 Lyman break sample. We find that according to our model, the color selection criteria used to select our z ~ 4 sample surveys 67% of all galaxies at this epoch down to z850 < 26.5. We find that our model predicts a ~40% mass buildup between the z ~ 4 and z ~ 3 epochs for the UV rest-frame L* galaxies. Furthermore, according to our model, at least 50% of the total stellar mass resides in relatively massive UV-faint objects that fall below our observational detection limit.
Topical Analysis of Interactions Between News and Social Media

The analysis of interactions between social media and traditional news streams is becoming increasingly relevant for a variety of applications, including: understanding the underlying factors that drive the evolution of data sources, tracking the triggers behind events, and discovering emerging trends.Researchers have explored such interactions by examining volume changes or information diffusions,however, most of them ignore the semantical and topical relationships between news and social media data.Our work is the first attempt to study how news influences social media, or inversely, based on topical knowledge.We propose a hierarchical Bayesian model that jointly models the news and social media topics and their interactions.We show that our proposed model can capture distinct topics for individual datasets as well as discover the topic influences among multiple datasets.By applying our model to large sets of news and tweets, we demonstrate its significant improvement over baseline methods and explore its power in the discovery of interesting patterns for real world cases.
Towards a better internet for children: findings and recommendations from EU Kids Online to inform the CEO coalition

This report presents new findings and further analysis of the EU Kids Online 25 country survey. It also brings together our previously published findings relevant to European Commission Vice President Kroes’ CEO Coalition recent initiative to make the internet a better place for children. New results how that, of nine different kinds of parental worries about their child, online risks – being contacted by strangers (33% parents) or seeing inappropriate content (32% parents) - rank 5th and 6th. Will the Coalition’s principles help manage online risk of harm, and so address parental concerns? Our evidence supports recommendations about initiatives that industry can take under four of the five headings considered by the CEO Coalition.
Effect Mechanisms of Perceptual Congruence Between Information Systems Professionals and Users on Satisfaction with Service

With the proliferation of available electronic service channels for information systems (IS) users such as mobile or intranet services in companies, service interactions between IS users and IS professionals have become an increasingly important factor for organizational business-IT alignment. Despite the increasing relevance of such interactions, the implications of agreement or disagreement on the fulfillment of critical service quality factors for successful alignment and higher user satisfaction are far from being well understood. While prior research has extensively studied the question of matching different viewpoints on IS service quality in organizations, little or no attention has been paid to the role of perceptual congruence or incongruence in the dyadic relationship between IS professionals and users in forming user satisfaction with the IS function. Drawing on cognitive dissonance theory, prospect theory, and perceptual congruence research, this study examines survey responses from 169 matching pairs of IS professionals and users in different organizations and explains how perceptual fit patterns affect user satisfaction with the IS function. The paper demonstrates that perceptual congruence can, in and of itself, have an impact on user satisfaction, which goes beyond what was found before. Moreover, the results of the study reveal the relevance of nonlinear and asymmetric effect mechanisms arising from perceptual (in)congruence that may affect user satisfaction. This study extends our theoretical understanding of the role of perceptual alignment or misalignment on IS service quality factors in forming user satisfaction and lays the foundation for further study of the interplay between perceptions in the dyadic relationship between IS professionals and IS users. Managers who seek to encourage particular behaviors by the IS professionals or IS users may use the results of this study to reconcile the often troubled business-IT relationship.
Shear Alfv'en wave continuous spectrum in the presence of a magnetic island

The continuous spectrum of shear Alfvén waves is calculated for a finite-beta tokamak equilibrium in the presence of a finite-size magnetic island. The beta-induced Alfvén Eigenmodes continuum accumulation point (BAE-CAP) is found to be positioned at the separatrix flux surface, while the frequency remains the same. The most remarkable novel feature is the presence of new CAPs at the island O-point, which give rise to gaps in the continuous spectrum. This could make the existence of new magnetic-island induced Alfvén Eigenmodes (MiAE) possible, excited via wave-particle resonances if the island is sufficiently wide with respect to the mode radial localization. Experimental data of modes observed in Frascati Tokamak Upgrade (FTU) are presented, which are consistent with theoretical scalings of the MiAE-CAPs. Due to the frequency dependence on the magnetic island size, the feasibility of utilizing this scaling as a novel magnetic island diagnostic is also discussed.
The State of Authorship in Criminology: Perceptions of Right and Order among Elite Criminologists

Abstract Although journal outlets are beginning to put forth explicit criteria that define authorship, studies have also found that there are nonetheless components of authorship philosophies that remain interactional and culturally defined among members of particular scientific communities. In line with other scientific fields, authorship practices and philosophies are central to publishing in criminology. By drawing from a set of 40 interviews with elite scholars in the field, this paper investigates authorship philosophies prominent in criminology. This paper contributes to knowledge on criminological research practices in two ways. First, this paper contributes to the scant literature on authorship in criminology by investigating cultural definitions of what constitutes authorship right and order. Second, this paper contrasts widespread notions of scientific literate practices as being universal and instead builds on a body of work suggesting that literate practices in scientific communities are culturally defined.
Analysis of Space-Time Codes using Serial Concatenation

Analytical expressions giving the performance of serially concatenated space-time codes are provided. These expressions lead to guidelines for achieving large gains through serial concatenation for space-time codes in wireless fading channels. They are similar to guidelines previously developed for regular convolutional codes in additive Gaussian noise channels. However, the justiication for these guidelines are not a direct extension of those previous results. The performance of two example serially concatenated space-time codes (SCSTC) is analyzed numerically. One code is designed for a quasi-static fading channel, the other for a fast fading channel. Simulation results show agreement with the guidelines provided. An iterative decoding scheme is used at the receiver. For applications which can tolerate delay, signiicant gain can be achieved with the proposed approach.
Concentration of platelets and growth factors in platelet-rich plasma from Goettingen minipigs

In minipigs little is known about the concentration of growth factors in plasma, despite their major role in several patho-physiological processes such as healing of fractures. This prompted us to study the concentration of platelets and selected growth factors in plasma and platelet-rich plasma (PRP) preparation of sixteen Goettingen minipigs. Platelet concentrations increased significantly in PRP in comparison to native blood plasma. Generally, significant increase in the concentration of all growth factors tested was observed in the PRP in comparison to the corresponding plasma or serum. Five of the plasma samples examined contained detectable levels of bone morphogenic protein 2 (BMP-2) whereas eleven of the plasma or serum samples contained minimal amounts of vascular endothelial growth factor (VEGF) and platelet-derived growth factor (PDGF-bb) respectively. On the other hand variable concentrations of bone morphogenic protein 7 (BMP-7) and transforming growth factor β1 (TGF-β1) were measured in all plasma samples. In contrast, all PRP samples contained significantly increased amounts of growth factors. The level of BMP-2, BMP-7, TGF-β1, VEGF and PDGF-bb increased by 17.6, 1.5, 7.1, 7.2 and 103.3 fold, in comparison to the corresponding non-enriched preparations. Moreover significant positive correlations were found between platelet count and the concentrations of BMP-2 (r=0.62, p<0.001), TGF-β1 (r=0.85, p<0.001), VEGF (r=0.46, p<0.01) and PDGF-bb (r=0.9, p<0.001). Our results demonstrate that selected growth factors are present in the platelet-rich plasma of minipigs which might thus serve as a source of autologous growth factors.
Product Review Summarization by Exploiting Phrase Properties

We propose a phrase-based approach for generating product review summaries. The main idea of our method is to leverage phrase properties to choose a subset of optimal phrases for generating the final summary. Specifically, we exploit two phrase properties, popularity and specificity. Popularity describes how popular the phrase is in the original reviews. Specificity describes how descriptive a phrase is in comparison to generic comments. We formalize the phrase selection procedure as an optimization problem and solve it using integer linear programming (ILP). An aspect-based bigram language model is used for generating the final summary with the selected phrases. Experiments show that our summarizer outperforms the other baselines.
Illegal Coal Mining in Eastern India: Rethinking Legitimacy and Limits of Justice

Commonly presented as arising from poor policing and corruption, and as raiders and destroyers of environmental commons, ‘illegal’ production and marketing of coal is a significant aspect of everyday life in eastern India. Such representations hide unpleasant social realities of the coal mining tracts: poor environmental performance of large mining projects of the state-owned mining sector, social disruption and displacement in both physical relocation and occupational changes of farming and forest-based communities, and a general decay in traditional subsistence bases of peasant and indigenous communities. To unveil the illegitimacy in mining and its various forms, this paper digs through the complex layers of mining laws and investigates whether the laws promote justice and equity and protect the interests of the disadvantaged. In doing so, it offers a rethinking of what causes and constitutes illegality with insights from the ground where a large number of people’s livelihoods depend on this kind of mining.
Dynamic Earthquake Ruptures in the Presence of Lithostatic Normal Stresses: Implications for Friction Models and Heat Production

We simulate dynamic ruptures on a strike-slip fault in homogeneous and layered half-spaces and on a thrust fault in a layered half-space. With traditional friction models, sliding friction exceeds 50% of the fault normal compressive stress, and unless the pore pressures approach the lithostatic stress, the rupture characteristics depend strongly on the depth, and sliding generates large amounts of heat. Under application of reasonable stress distributions with depth, variation of the effective coefficient of friction with the square root of the shear modulus and the inverse of the depth creates distributions of stress drop and fracture energy that produce realistic rupture behavior. This ad hoc friction model results in (1) low-sliding friction at all depths and (2) fracture energy that is relatively independent of depth. Additionally, friction models with rate-weakening behavior (which form pulselike ruptures) appear to generate heterogeneity in the distributions of final slip and shear stress more effectively than those without such behavior (which form cracklike ruptures). For surface rupture on a thrust fault, the simple slip-weakening friction model, which lacks rate-weakening behavior, accentuates the dynamic interactions between the seismic waves and the rupture and leads to excessively large ground motions on the hanging wall. Waveforms below the center of the fault (which are associated with waves radiated to teleseismic distances) indicate that source inversions of thrust events may slightly underestimate the slip at shallow depths.
A Role of Ventral Tegmental Area Glutamate in Contextual Cue-Induced Relapse to Heroin Seeking

The environmental context previously associated with opiate use plays an important role in human relapse, but the neuronal mechanisms involved in context-induced drug relapse are not known. Using a rat relapse model, we determined the effect of a group II metabotropic glutamate receptor agonist [LY379268 ((-)-2-oxa-4-aminobicylco hexane-4,6-dicarboxylic acid)] on contextual cue-induced reinstatement of heroin seeking. LY379268, which acts centrally to reduce evoked glutamate release, was injected systemically or directly into the ventral tegmental area (VTA), a brain area involved in opiate reward and conditioned drug effects. Rats were trained to self-administer intravenous heroin for 12 d; drug infusions were paired with a discrete tone-light cue. Subsequently, lever pressing was extinguished in the presence of the discrete cue in a context that differed from the drug self-administration context in terms of visual, auditory, tactile, and circadian cues. After extinction of lever responding, LY379268 was injected systemically or into the VTA, and nonreinforced responding was determined in the extinction context or the drug context. Exposure to the heroin-associated context induced robust reinstatement of drug seeking, and this effect was attenuated by systemic or intra-VTA injections of LY379268. Results indicate that glutamate transmission in the VTA plays an important role in contextual cue-induced relapse to heroin seeking.
