Individual Differences as Predictors of Social Networking
Research suggests that personality dictates specific Internet preferences. One area that remains relatively unexplored is the influence of personality on engagement with social networking sites (SNSs). The current study employs a ‘Uses and Gratifications’ framework to investigate whether personality, age, and sex predict motivations for using SNSs. The study explores both global and specific factors of personality using Eysenck's EPQ-R short form (extraversion, neuroticism and psychoticism) and Beck's SAS (sociotropy and autonomy). Principal component analysis identified ten distinct motivational components, which were then successfully predicted by individual differences through regression analyses. It is therefore suggested that individuals with different profiles vary in their motivations for using SNSs. Results support theoretical assumptions based on previous literature and personality dispositions
Investigating the Facebook experience through Q Methodology: Collective investment and a ‘Borg’ mentality
Several recent studies have explored social networking sites, such as Facebook, in light of the uses and gratifications approach. However, research has tended to ignore the latter part of this paradigm. This article uses Q methodology to explore user experiences of Facebook, allowing further exploration of gratification from site usage. Four distinct viewpoints were found: Facebook as a superficial environment; Facebook as a valid and valuable social environment; Facebook as an environment of surveillance; and Facebook as a destructive environment. Although the viewpoints show elements of user satisfaction, some users view Facebook in an almost entirely negative way. The article concludes by theorising a model of Facebook usage, drawing upon a metaphor from Star Trek, specifically an analogy with the Borg. It is argued that a level of ‘collective investment’ resides over social networks that may sometimes promote compliance
The subduction experiment : cruise report R/V Knorr : cruise number 138 leg XV : subduction 3 mooring recovery cruise, 13-30 June 1993
Subduction is the mechanism by which water masses formed in the mixed layer and near the surface of the ocean find their
way into the upper thermocline. The subduction process and its underlying mechanisms were studied though a combination of
Eulerian and Langrangian measurements of velocity, measurements of tracer distributions and hydrographic properties and modeling.
An array of five surface moorings carrying meteorological and oceanographic instrumentation were deployed for a period of
two years beginning in June 1991 as part of an Office of Naval Research (ONR) funded Subduction experiment. Three eight month
deployments were planned. The moorings were deployed at 18°N 34°W, 18°N 22°W, 25.5°N 29°W, 33°N 22°W and 33°N 34°W.
A Vector Averaging Wind Recorder (VAWR) and an Improved Meteorological Recorder (IMET) collected wind speed and
wind direction, sea surface temperature, air temperature, short wave radiation, barometric pressure and relative humidity. The IMET
also measured precipitation. The moorings were heavily instrumented below the surface with Vector Measuring Current Meters
(VMCM) and single point temperature recorders.
Expendable bathythermograph (XBT) data were collected and meteorological observations were made while transmitting
between mooring locations.
This report describes the work that took place during R/V Knorr cruise number 138 leg XV which was the fourth scheduled
Subduction mooring cruise. During this cruise the moorings previously deployed for a third and final eight month period were
recovered. This report includes a description of the moorings and instrumentation that were recovered, has information about the
underway measurements (XBT and meteorological observations) that were made including plots of the data, and presents a chronology
of the cruise events.Funding provided by the Office of Naval Research under

Report and Recommendations on the Economic Impact of the Historic Environment in Scotland
This report is submitted by HEACS, the Historic Environment Advisory Council for Scotland, which was established in 2003 to provide Scottish Ministers with strategic advice on issues affecting the historic environment. In its second term HEACS was asked by the Scottish Ministers: To identify for Scottish Ministers the economic impact of the historic environment in Scotland. In 2008 HEACS commissioned an economic impact study of the historic environment from ECOTEC Research and Consulting Ltd. The Project Steering Group comprised the HEACS Economic Significance Working Group, augmented by economists from the Scottish Government and the Fraser of Allander Institute. The project also benefited from close liaison with Historic Scotland throughout. The primary aim of the economic impact study was that it should establish for the first time a robust set of estimates for the economic contribution of Scotland's historic environment to the nation's economy. The remit of the project was tightly drawn in order to ensure that the Government and wider sector could have confidence in the results. The results of this study should therefore be regarded as a conservative assessment of the economic contribution of the historic environment in Scotland. This HEACS report is intended to be read as an introduction to and in conjunction with the ECOTEC report, Economic Impact of the Historic Environment in Scotland, which is also submitted in its entirety to the Scottish Ministers
The Emergence and Evolution of the Multidimensional Organization
The article discusses multidimensional organizations and the evolution of complex organizations. The six characteristics of multidimensional organizations, disadvantages of the successful organizational structure that is categorized as a multidivisional, multi-unit or M-form, research by the Foundation for Management Studies which suggests that synergies across business divisions can be exploited by the M-form, a team approach to creating economic value, examples of multidimensional firms such as PricewaterhouseCoopers, and a comparison of various organization types including the matrix form are mentioned
Creating an Antibacterial with in Vivo Efficacy: Synthesis and Characterization of Potent Inhibitors of the Bacterial Cell Division Protein FtsZ with Improved Pharmaceutical Properties
3-Methoxybenzamide (1) is a weak inhibitor of the essential bacterial cell division protein FtsZ. Alkyl derivatives of 1 are potent antistaphylococcal compounds with suboptimal drug-like properties. Exploration of the structure-activity relationships of analogues of these inhibitors led to the identification of potent antistaphylococcal compounds with improved pharmaceutical properties

Pan-Cancer Analysis of lncRNA Regulation Supports Their Targeting of Cancer Genes in Each Tumor Context
Long noncoding RNAs (lncRNAs) are commonly dys-regulated in tumors, but only a handful are known toplay pathophysiological roles in cancer. We inferredlncRNAs that dysregulate cancer pathways, onco-genes, and tumor suppressors (cancer genes) bymodeling their effects on the activity of transcriptionfactors, RNA-binding proteins, and microRNAs in5,185 TCGA tumors and 1,019 ENCODE assays.Our predictions included hundreds of candidateonco- and tumor-suppressor lncRNAs (cancerlncRNAs) whose somatic alterations account for thedysregulation of dozens of cancer genes and path-ways in each of 14 tumor contexts. To demonstrateproof of concept, we showed that perturbations tar-geting OIP5-AS1 (an inferred tumor suppressor) andTUG1 and WT1-AS (inferred onco-lncRNAs) dysre-gulated cancer genes and altered proliferation ofbreast and gynecologic cancer cells. Our analysis in-dicates that, although most lncRNAs are dysregu-lated in a tumor-specific manner, some, includingOIP5-AS1, TUG1, NEAT1, MEG3, and TSIX, synergis-tically dysregulate cancer pathways in multiple tumorcontexts
Pan-cancer Alterations of the MYC Oncogene and Its Proximal Network across the Cancer Genome Atlas
Although theMYConcogene has been implicated incancer, a systematic assessment of alterations ofMYC, related transcription factors, and co-regulatoryproteins, forming the proximal MYC network (PMN),across human cancers is lacking. Using computa-tional approaches, we define genomic and proteo-mic features associated with MYC and the PMNacross the 33 cancers of The Cancer Genome Atlas.Pan-cancer, 28% of all samples had at least one ofthe MYC paralogs amplified. In contrast, the MYCantagonists MGA and MNT were the most frequentlymutated or deleted members, proposing a roleas tumor suppressors.MYCalterations were mutu-ally exclusive withPIK3CA,PTEN,APC,orBRAFalterations, suggesting that MYC is a distinct onco-genic driver. Expression analysis revealed MYC-associated pathways in tumor subtypes, such asimmune response and growth factor signaling; chro-matin, translation, and DNA replication/repair wereconserved pan-cancer. This analysis reveals insightsinto MYC biology and is a reference for biomarkersand therapeutics for cancers with alterations ofMYC or the PMN
