Real-Time Social Event Analytics

Managing public safety at large events is important. Crowd control and traffic management are particularly relevant for non-ticketed events in public spaces. In such cases, it can be difficult for organisers to anticipate the number of people who will attend and to validate the event’s success [1]. Given the ubiquitous nature of mobile phones, Call Detail Records (CDRs), which are the logs of user transactions with a mobile phone service provider, have been widely used to study urban processes [2], [3], [4]. By building on the work of [5] and [6] our research explores the use of real-time CDR data as a proxy to estimate the density of crowds in different areas of a city while events are taking place. The research has also been extended to estimate the density of vehicles on the main access routes to a city. This has led to the development of an application entitled Social Event Analytics (SEA) which provides both real-time and historic information about crowd and vehicle densities. The application can be used by authorities and event organisers to manage the event and gauge its success. The application was used in January 2015 for monitoring city wide events in Mons, Belgium which marked the launch of Mons as the European City of Culture for 2015. Using SEA local police simultaneously monitored the density of vehicles on the road network and the crowd density in different areas of the city. Below, we briefly describe the new real-time data analysis which we carried out for this specific case in which over 20 million CDRs were analysed each day. The results are useful for authorities but will also help to further our knowledge of human processes in urban environments.

The aim of this investigation is determining the impression and risk of SMES in developing financial constant in accepted companies in Tehran money exchange. This is a kind of library and analytic-scientific investigation. In this investigation the financial information of 104 accepted companies in Tehran money exchange during 1387 to 1392 were determined. (624 companies every year) for analyzing the results soft wares such as Minitab 16 – Eviews7 and Spss20 were used. The results of the research showed that there is a meaning full and straight relation between SMES and added value. Also there is a meaning ful and reversed relation between risk of SMES and intrinsic value.
Unintended consequences of a strategically ambiguous organizational policy selectively restricting mobile device use at work

Mobile devices have permeated organizations creating diverse communication opportunities and new organizational challenges. This case study examines one of those challenges: creating a strategically ambiguous mobile device use policy to combat misuse in an organization. We use focus group data collection and a subsequent constant comparative analysis to examine a U.S. company with an organizational policy selectively restricting mobile device access for nonmanagerial workers. The findings and resulting theoretical model reflect the tension employees face when interpreting a restrictive mobile device use policy within the context of mobile use as “taken for granted. ” This tension is manifest through four unintended consequences of the strategically ambiguous policy: (a) declining productivity, (b) supervisors burdened by overwhelming tasks, (c) decreased professional mobility, and (d) fleeting organizational identification. This research offers an organizational contribution to the current work on mobiles and it provides insight into how nonmanagerial workers interpret and act when a mobile use policy is strategically ambiguous.
PD-L1 and PD-L2 are differentially regulated by Th1 and Th2 cells

PD-L1 and PD-L2 are ligands for PD-1, a costimulatory molecule that plays an inhibitory role in regulating T cell activation in the periphery. We find that PD-L1 is highly expressed on inflammatory macrophages as compared with resident peritoneal macrophages but can be induced on resident macrophages by classical activation stimuli such as lipopolysaccharide, IFN-γ, and polyinosinic-polycytidylic acid. Further up-regulation of PD-L1 on inflammatory macrophages can also be induced by subsequent exposure to lipopolysaccharide and IFN-γ. In contrast, PD-L2 is not expressed on inflammatory macrophages but can be induced by alternative activation via IL-4. Although PD-L1 is highly inducible on a variety of antigen-presenting cell lines as well as resident macrophages, PD-L2 is most significantly inducible only on inflammatory macrophages. PD-L1 up-regulation depends on TLR4 and STAT1, whereas PD-L2 expression depends on IL-4Rα and STAT6. Consistent with these results, T helper 1/T helper 2 (Th1/Th2) cells also differentially up-regulate PD-L1 and PD-L2 expression on inflammatory macrophages. Hence, Th1 cells as well as microbial products can enhance PD-L1 expression on many different macrophage populations, whereas Th2 cells instruct only inflammatory macrophages to up-regulate PD-L2. These results suggest that PD-L1 and PD-L2 might have different functions in regulating type 1 and type 2 responses.
A Summary of Convective-Core Vertical Velocity Properties Using ARM UHF Wind Profilers in Oklahoma

This study presents a summary of the properties of deep convective updraft and downdraft cores over the central plains of the United States, accomplished using a novel and now-standard Atmospheric Radiation Measurement Program (ARM) scanning mode for a commercial wind-profiler system. A unique profilerbased hydrometeor fall-speed correction method modeled for the convective environment was adopted. Accuracyofthevelocity retrievalsfromthis effortis expectedtobe within2ms 21 , with minimalbiasandbase core resolution expected near 1km. Updraft cores are found to behave with height in reasonable agreement with aircraft observations of previous continental convection, including those of the Thunderstorm Project. Intense updraft cores with magnitudes exceeding 15ms 21 are routinely observed. Downdraft cores are less frequently observed, with weaker magnitudes than updrafts. Weak, positive correlations are found between updraft intensity (maximum) and updraft diameter length (coefficient r to 0.5 aloft). Negligible correlations are observed for downdraft core lengths and intensity.
Agouti and Agouti-related Protein: Analogies and Contrasts*

The discovery a decade ago of the murine agouti gene was intended to bring scientists a step closer to understanding the complexities of mammalian pigmentation. The first obesity gene was also uncovered in the process. What followed was an explosion of major discoveries in murine as well as human obesity and diabetes research. Recently, a new gene, the agouti-related protein (AGRP), was discovered and found to share a striking similarity in structure and function with agouti, although their patterns of distribution are completely different. Identification of a hypothalamic melanocortin receptor, MC4-R, together with AGRP as central components of feeding behavior and metabolism has helped build a picture, albeit incomplete, of the neuronal pathways involved in energy homeostasis. This review will compare and contrast Agouti and AGRP structure and function and gene regulation and their interaction with melanocortin receptors (MC1-R and MC4-R) and suppressors (mahogany/mahoganoid).
Culture and Project Management

Abstract Project management in every situation is based on planning, organizing, motivating and controlling resources for the attainment of certain goals. This essentially means that the success of the management of a project will depend on the results achieved as well as the resources committed in achieving such results. Irrespective of the objectives of a project, one fundamental fact remains significant, that is, the fact that projects are geared towards the improvement of conditions in a particular society. This article is interested not only in the art of project management but also the factors which could influence the success or failure of these projects. In this article, the influence of the culture of the society for which a project is meant will be examined to find out whether it influences the conception and implementation of the project in any way. In this regard some case studies of projects will be studied to find out the extent to which the cultural context of the society played a significant role in particular projects. The other case which will receive attention in this write up will be the significance of culture at each stage of the project. These elements will be discussed paying particular attention to the dimensions of culture proposed by Hofstede and how they influence the project management process. The conclusion of this article will propose an approach to project management which takes into consideration the cultural context in which the project will be realized and the stages of the project management process which should involve more cultural orientation
The Naked Truth

ABSTRACT Graphic sexual appeals grab attention but the advertising literature suggests that these messages are far from a “magic bullet. ” Using a large national panel (N = 1,506), the current research manipulated levels of nudity in fragrance ads and assessed key constructs including Sexual Self Schema, Sensation Seeking, and dimensions of the Reidenbach-Robin Multi-dimensional Ethics Scale to determine which factors best account for individual response. Findings indicate that elements of all three variables were important predicators of viewers' emotional, attitudinal, and behavioral responses, especially as nudity increased. The results elucidate key factors for managerial action when incorporating sexual appeals in brand building.
Accountability, completeness, credibility and the audit expectations gap.

This article deals with two concerns in achieving greater accountability in social reports: the lack of completeness of reporting, and the lack of credibility of reports. The article focuses, in particular, on the role of social audits in improving the completeness and credibility of reporting, thereby reducing the audit expectations gap. We suggest that this gap arises due to an over-emphasis on the validity of performance data at the expense of addressing completeness and credibility, both of which, we argue, require stakeholder involvement. The article reviews recent guidelines aimed at ensuring that companies produce reports that are complete in all material respects including those produced by the Global Reporting Initiative and the Federation des Experts Comptables Europeens, focusing particularly on AccountAbility’s AA1000 Standard and AA1000S Assurance Standard. Finally, the article considers the development of a practical approach to social audit following principles increasingly being incorporated into developing assurance guidelines aimed at reducing the audit expectations gap. ● Social auditing ● Accountability ● Audit expectations gap
Multicenter epidemiologic study on hepatocellular carcinoma in Turkey.

BACKGROUND Hepatocellular cancer (HCC) is one of the important health problems in Turkey, being very common and highly lethal. The aim of this study was to determine clinical, demographic features and risk factors. MATERIALS AND METHODS Nine hundred and sixth-three patients with HCC from 13 cities in Turkey were included in this study. RESULTS Only 205 (21%) of the 963 patients were women, with a male:female predominance of 4.8:1 and a median age of 61 years. The etiologic risk factors for HCC were hepatitis B in 555 patients (57.6%), 453 (81%) in men, and 102 (19%) in women, again with male predominance, hepatitis C in 159 (16.5%), (14.9% and 22.4%, with a higher incidence in women), and chronic alcohol abuse (more than ten years) in 137 (14.2%) (16.8% and 4.9%, higher in males). The Child-Pugh score paralleled with advanced disease stage amd also a high level of AFP. CONCLUSIONS According to our findings the viral etiology (hepatitis B and hepatitis C infections) in the Turkish population was the most important factor in HCC development, with alcohol abuse as the third risk factor. The Child-Pugh classification and AFP levels were determined to be important prognostic factors in HCC patients.
Corporate Social Networks within the Financial Sector

This study has been conducted with Sirius International as a case company. The investigation has revolved around the weaknesses Sirius, along with the authors, have identified concerning the international collaboration and communication. It was later shown that these problems were based on a low sense of unity in the organization as a result of the lack of knowledge sharing, knowledge management, and spread of organization related information. It was decided to evaluate whether a corporate social network (CSN) could assist in these problems and if so, decide what system would be the most appropriate in regards to the internal needs and requirements at Sirius. The major challenges brought on with an implementation of a CSN, and how to face these, were investigated as a part of the evaluation whether a CSN would be appropriate for Sirius or not. The study showed that a CSN was an appropriate choice for Sirius in order to improve the international communication, collaboration, and unity. The most suitable choice was determined to be Yammer, as it best suited the internal requirements and needs. Along with these results, the largest challenge with an implementation and future use of the system was user acceptance and overall usage of the system. If the CSN is not used, none of the visions, goals, or purposes will be fulfilled.

Apparel Brands` Implementation and Customers` Expectation of Mass Customization

Apparel goods can be customer-oriented in the extreme and the apparel industry is one of the most customer-centered industries that should maximize customers` satisfaction. Recently, mass customization, a customer-centered system is widely discussed in the apparel industry to provide consumers with new, differentiating, distinctive, yet personalized products. The purpose of this study is to provide useful insights for apparel brands` mass customization(hereafter, MC) implementation by comparing the apparel brands` current status with consumers` expectation. One hundred apparel brands` practitioners and 116 consumers were surveyed in this research. First, we found that, on the basis of the five stages of MC presented by Pine(1993), apparel brands` MC stages were identified. Then, customers` expectation levels were examined according to the five stages. When compared the gap between the customers` expectation level and the apparel brands` implementation, consumers` expectation of MC was significantly higher than the implementation level by apparel brands for the stage 2(customized products creation), the stage 5(modular production). Second, by conducting a factor analysis with the scales measuring the MC activities of the five stages, apparel brands` current MC strategies could be classified as `mass customized strategy`, `quick response strategy`, `MOT(moment of truth) customized strategy`, and `individualized service strategy. ` Apparel brands showed significant differences in mass customized strategy, quickresponse strategy, and MOT customized strategy according to their product characteristics. Finally, consumers` expectation level of MC strategies was significantly different by their characteristics such as shopping orientation.

The impact of international market effects and pure political risk on the major western oil and gas stock market sectors

A key question in European integration is whether or not the global oil and gas market sector (over the period which includes the oil price hikes of 2001 to late 2007 and the global financial crisis from mid 2008 to early 2009) has been impacted to a greater or lesser extent by major Western country oil and gas stock market sectors (such as, those in the USA, the EMU and the UK) as well as political, social and legal factors (embodied in political risk ratings) for the USA, the UK and the key economies of the EMU (that is, France, Germany and Italy). This short study uses analysis of both unlagged and lagged data in multivariate models to test these relationships and finds a closer relationship politically and financially between the USA and the UK than between the EMU and the UK markets. The EMU and the major EMU countries considered separately in oil and gas market sector movements and political risk ratings movements have very little financial and political influence on the movement of the global oil and gas market sector over the period.
Diabetes complications severity index and risk of mortality, hospitalization, and healthcare utilization.

OBJECTIVE To determine whether the number and severity of diabetes complications are associated with increased risk of mortality and hospitalizations. STUDY DESIGN Validation sample. METHODS The Diabetes Complications Severity Index (DCSI) was developed from automated clinical baseline data of a primary care diabetes cohort and compared with a simple count of complications to predict mortality and hospitalizations. Cox proportional hazard and Poisson regression models were used to predict mortality and hospitalizations, respectively. RESULTS Of 4229 respondents, 356 deaths occurred during 4 years of follow-up. Those with 1 complication did not have an increased risk of mortality, whereas those with 2 complications (hazard ratio [HR] = 1.90, 95% confidence interval [CI] = 1.27, 2.83), 3 complications (HR = 2.66, 95% CI = 1.77, 4.01), 4 complications (HR = 3.41, 95% CI = 2.18, 5.33), and >5 complications (HR = 7.18, 95% CI = 4.39, 11.74) had greater risk of death. Replacing the complications count with the DCSI showed a similar mortality risk. Each level of the continuous DCSI was associated with a 1.34-fold (95% CI = 1.28, 1.41) greater risk of death. Similar results were obtained for the association of the DCSI with risk of hospitalization. Comparison of receiver operating characteristic curves verified that the DCSI was a slightly better predictor of mortality than a count of complications (P < .0001). CONCLUSION Compared with the complications count, the DCSI performed slightly better and appears to be a useful tool for prediction of mortality and risk of hospitalization.
Biodiversity and tissue-recurrence of endophytic fungi in Tripterygium wilfordii

, 2000; Tan and Zou, 2001). If these fungi could be utilized to produce the bioactive compounds of medicinal plants on large-scale fermentors, this would provide a new technology for producing many types of Traditional Chinese medicine. Some endophytic fungi have been found to produce similar medicinal compounds to that of the host. Proof of principal was realized when the anticancer drug taxol was found to be produced by endophytic fungi isolated from
Institutional factors in subsidiaries technology strategies

: How subsidiaries arrive at technological strategies that may become emergent at the global level? Fossil fuel cars dominate the world markets. Now, flex fuel cars are the Brazilian local dominant design. Clearly, subsidiaries made differing choices in market entry timing and engine compression ratios. Why did the main Brazilian auto industry subsidiaries get deeply involved with flexible fuel cars? How did they arrive at their current technology strategies? To explain their strategies, one must consider Brazil’s local institutional factors a large and fast growing local market, the long sugar cane history, government incentives, the subsidiaries’ relevance to their headquarters, their early involvement in the development of ethanol-fueled vehicles, and the subsidiaries’ differing R&D autonomies.
CCD camera calibration virtual equivalent model

We propose an equivalence between any camera with inherent technical limitations (optic, solid-state sensor, digitizer) [1] and a perfect virtual pin hole camera model. The view of a reference plane grid gives a discretization of every camera defect. Opposite transformation allows elaboration of a virtual sensor as perfect as possible. This bijection based on interpolation concepts takes all the deformations (distortion, decentering, scale and affinity ratios) generated by the optical and electronical equipment in account without the need for their explicit determination. The only remaining intrinsic parameters to determine are the coordinates (Uo', Vo', F') of the focus point in the virtual sensor. An original detection method of this grid image, particularly adapted to this problem, provides a good precision on real grid images (errors standard deviation inferior to 0,012 pixels with an of-the-shelf camera 512×512 and 256 grey levels).
Exploring the components of success for the Korean chaebols

Purpose – This paper aims to discuss the profiles of Korean chaebols involved in global electronicsDesign/methodology/approach – The research was conducted among 132 of their Korean suppliers, with linked in‐depth interviews with chaebol managers. From an initial set of literature‐based variables, factor analysis is used to generate six chaebol characteristics, which are then correlated with four chaebol‐supplier relationship outcomes.Findings – “Decision making” and “social exchange”, in particular, are found to correlate positively with all four chaebol‐supplier relationship outcome measures, relationship satisfaction, performance, cooperation and conflict resolution. “Partnership” is associated positively with three of these outcomes, and “strategy‐longevity” with relationship satisfaction. The chaebols' “structure‐control” and “leadership” are not found to be predictors of successful relationship outcomes as measured in this study. A combination of higher quality, lower cost products with linkages to .
