TL;DR: It is concluded that IA may pose a serious health hazard to a minority of people and there is no consensual definition for IA, with implications for treatment, prevention, and patient-specific considerations.
Abstract: Research into Internet addiction (IA) has grown rapidly over the last decade The topic has generated a great deal of debate, particularly in relation to how IA can be defined conceptually as well as the many methodological limitations The present review aims to further elaborate and clarify issues that are relevant to IA research in a number of areas including: definition and characterization, incidence and prevalence rates, associated neuronal processes, and implications for treatment, prevention, and patient-specific considerations It is concluded that there is no consensual definition for IA Prevalence rates among nationally representative samples across several countries vary greatly (from 1% to 187%), most likely reflecting the lack of methodological consistency and conceptual rigor of the studies The overlaps between IA and other more traditional substance-based addictions and the possible neural substrates implicated in IA are also highlighted In terms of treatment and prevention, both psychological and pharmacological treatments are examined in light of existing evidence alongside particular aspects inherent to the patient perspective Based on the evidence analyzed, it is concluded that IA may pose a serious health hazard to a minority of people

TL;DR: In this article, the role of inter-organizational networks as facilitators of knowledge flow and innovation is discussed, and the authors introduce the concepts of network capital and network space to complement existing notions of social capital and geographic space as explanatory factors underpinning the impact of networks.
Abstract: This paper focuses on the role of inter-organizational networks as facilitators of knowledge flow and innovation. It introduces the concepts of network capital and network space to complement existing notions of social capital and geographic space as explanatory factors underpinning the impact of networks. Empirically, the paper analyses the inter-organizational networks of firms across three different regional settings. As well as finding significant differences across regions, the analysis also finds cross-regional commonalities in terms of the association between the innovation prowess of firms and the nature of their networks. In particular, it is found that the innovation performance of firms is significantly related to network capital investment in dynamically configured inter-organizational knowledge alliances. It is concluded that such findings may provide clues in terms of policy making in areas such as cluster and innovation system development, especially in supporting and orchestrating networks which have a clear strategic and calculative rationale.

TL;DR: In this article, a technique for the production of large areas of high aspect-ratio patterns and describe their use as model super-hydrophobic systems is presented. But this technique requires the use of photoresist patterns without micromoulding.
Abstract: In this work we present a reliable technique for the production of large areas of high aspect-ratio patterns and describe their use as model super-hydrophobic systems. The high thickness and straight sidewalls possible with SU-8 were used to generate dense patterns of small pillars. These photoresist patterns could be used directly, without the need for micromoulding. A method is given allowing resist thickness to be varied over a wide range and a bottom antireflective layer was used to simplify patterning on reflective substrates. This patterning technique allows rapid testing of wetting theories, as pattern size and depth can be varied simply and samples can be produced in sufficient numbers for laboratory use. We show how the static contact angle of water varies with pattern height for one sample-pattern and how static and dynamic contact angles vary with dimension using high aspect-ratio patterns.

TL;DR: High rate capability and ultrastable cycle stability are achieved in the 2D-PAI@CNT cathode, which far exceeds the state-of-the-art polyimide electrodes.
Abstract: Organic electrode materials are of long-standing interest for next-generation sustainable lithium-ion batteries (LIBs). As a promising cathode candidate, imide compounds have attracted extensive attention due to their low cost, high theoretical capacity, high working voltage, and fast redox reaction. However, the redox active site utilization of imide electrodes remains challenging for them to fulfill their potential applications. Herein, the synthesis of a highly stable, crystalline 2D polyarylimide (2D-PAI) integrated with carbon nanotube (CNT) is demonstrated for the use as cathode material in LIBs. The synthesized polyarylimide hybrid (2D-PAI@CNT) is featured with abundant π-conjugated redox-active naphthalene diimide units, a robust cyclic imide linkage, high surface area, and well-defined accessible pores, which render the efficient utilization of redox active sites (82.9%), excellent structural stability, and fast ion diffusion. As a consequence, high rate capability and ultrastable cycle stability (100% capacity retention after 8000 cycles) are achieved in the 2D-PAI@CNT cathode, which far exceeds the state-of-the-art polyimide electrodes. This work may inspire the development of novel organic electrodes for sustainable and durable rechargeable batteries.

TL;DR: This approach reveals the existence of multiple circulating subtypes of the major drug–resistant clade of the important pathogenic E. coli lineage ST131 and provides the first ever population level evidence of core genome substitutions in gene regulatory regions associated with the acquisition and maintenance of different accessory genome elements.
Abstract: The use of whole-genome phylogenetic analysis has revolutionized our understanding of the evolution and spread of many important bacterial pathogens due to the high resolution view it provides. However, the majority of such analyses do not consider the potential role of accessory genes when inferring evolutionary trajectories. Moreover, the recently discovered importance of the switching of gene regulatory elements suggests that an exhaustive analysis, combining information from core and accessory genes with regulatory elements could provide unparalleled detail of the evolution of a bacterial population. Here we demonstrate this principle by applying it to a worldwide multi-host sample of the important pathogenic E. coli lineage ST131. Our approach reveals the existence of multiple circulating subtypes of the major drug–resistant clade of ST131 and provides the first ever population level evidence of core genome substitutions in gene regulatory regions associated with the acquisition and maintenance of different accessory genome elements.
