Published: February 2017

<p>Person detection and tracking in crowd is a challenging task. We detect the head region and based on this head region we can detect people from crowd. Individual object detection has been improved significantly in recent times but the crowd detection and tracking contains some challenges. Crowd analysis is a highly focused area for law enforcement, urban engineering and traffic management. There are a lot of incident occurred in crowd area during some fabulous event. In this research low resolution and verities of image orientation is a key factor as well as overlapping person images in crowd misguided the system. An enhanced system of interest point detection based on gradient orientation information as well as improved feature extraction HOG is used for identifying the human head or face from crowd. We have analyzed different types of images in different varieties and found accuracy 88-90%. In a number of applications, such as document analysis and some industrial machine vision tasks, binary images can be used as the input to algorithms that perform useful tasks. These algorithms can handle tasks ranging from very simple counting tasks to much more complex recognition, localization, and inspection tasks. Thus by studying binary image analysis before going on to gray-tone and color images, one can gain insight into the entire image analysis process.</p>

Authors: Andrikogiannopoulou Angie , Papakonstantinou Filippos 
Published: February 2017

We use novel data on individual activity in a sports betting market to study the effect of past performance sequences on individual behavior in a real market. The idiosyncratic nature of risk in this market and the revelation of assets’ true terminal values enables us to disentangle whether behavior is caused by sentiment or by superior information about market mispricings and to cleanly test two prominent theories of momentum and reversals—the regime-shifting model of Barberis et al. [Barberis N, Shleifer A, Vishny R (1998) A model of investor sentiment. J. Financial Econom. 49(3):307–343] and the gambler’s/hot-hand fallacy model of Rabin [Rabin M (2002) Inference by believers in the law of small numbers. Quart. J. Econom. 117(3):775–816]. Furthermore, our long panel enables us to study the prevalence across individuals of each type of behavior. We find that (i) three-quarters of individuals exhibit trend-chasing behavior, (ii) seven times as many individuals exhibit behavior consistent with Barberis et al. (1998) as exhibit behavior consistent with Rabin (2002), and (iii) no individuals earn superior returns from momentum trading.This paper was accepted by Lauren Cohen, finance.

Summary
Gnathostomiasis is a prevalent zoonosis in humans in some regions of the world. The genus Gnathostoma is considered an accidental parasite for humans; G. binucleatum is the endemic species in Nayarit, Mexico. This work was designed to determine the proteolytic activity of the excretory-secretory products (ESP) of advanced third-stage larvae (ADVL3) of Gnathostoma binucleatum against human fibronectin and antibodies from human and sheep. Our findings showed protease activity against human fibronectin as well as sheep and human gamma globulins of the ESP at molecular weights of 80 and 56 kDa. The proteases found in the ESP of G. binucleatum are thus candidate molecules for consideration as pathogenic elements, owing to the fact that they destroy proteins of the host tissue, which probably allows them to migrate through those tissues and degrade molecules involved in the humoral immune response.
Effect of body composition on walking economy

Published: February 2017

PurposeThe aim of the study was to evaluate walking economy and physiological responses at two walking speeds in males with similar absolute body mass but different body composition.MethodsThe study involved 22 young men with similar absolute body mass, BMI, aerobic performance, calf and thigh circumference. The participants differed in body composition: body fat (HBF group) and lean body mass (HLBM group). In the graded test, maximal oxygen uptake (VO<sub>2max</sub>) and maximal heart rate were measured. Walking economy was evaluated during two walks performed at two different speeds (4.8 and 6.0 km h<sup>–1</sup>).ResultsThe VO<sub>2max</sub> was similar in both groups, as were the physiological responses during slow walking. The absolute oxygen uptake or oxygen uptake relative to body mass did not significantly differentiate the studied groups. The only indicator significantly differentiating the two groups was oxygen uptake relative to LBM.ConclusionsBody composition does not significantly affect walking economy at low speed, while during brisk walking, the economy is better in the HLBM vs. HBF group, provided that walking economy is presented as oxygen uptake relative to LBM. For this reason, we recommend this manner of oxygen uptake normalization in the evaluation of walking economy.
Vision Impossible? Some Aspects of the Current Russian Debates about the Military Sciences
Authors: Eklund Niklas 
Published: February 2017

AbstractIn 21stcentury military theory and doctrine, it is common to subdivide military capability into conceptual, physical and moral components. At least in theory, it follows that conceptual capability should be regarded as the crucial link between the physical and moral capabilities of a given military actor, as it concerns the ability of the actor to operationalise ideas about how to conduct modem warfare. Conceptual military capability can thus be defined as the sum of an actor’s military know­how, scientific capacity and doctrine, which defines the expected ability of an actor to uphold an efficient language of military action, distribution and command.
Narration of Lives and Nations

Published: February 2017

AbstractIran was one of the participants in the 2006 football World Cup (WC) in Germany. A special WC programme on TV2, one of two primary Norwegian TV channels, entitledWorld Cup Studio (Norwegian: VM-studio),offered various reports for a Norwegian audience and was sent before and after each match along with a short segment of reportage from the countries involved. The present article focuses on one of theWorld Cup Studioprogrammes broadcast during the WC games between Iran and Mexico. The purpose of the article is to investigate how Iran and Mexico, as two national and cultural entities, are presented in relation to a Norwegian socio-cultural context. Additionally, the particular geopolitical condition at the time before the World Cup, as represented in these programmes, is identified and classified.
Watching Handball Transmissions.
Authors: Frandsen Kirsten 
Published: February 2017

AbstractThe current article presents a qualitative study of Danish television viewer’s reception of Danish handball transmissions. The overall aim of the study has been to contribute to a more nuanced understanding of televised sport as a specific kind of television entertainment. The analysis shows that, due to the dramaturgic structure of handball transmissions, viewers consider such transmissions particularly reliable and effective sources of entertainment. The transmissions’ entertainment value derives from their specific ability to give the viewers a complex experience of feeling autonomous and competent when mastering the game and in relation to others. The study shows that entertainment concerns both affective involvement and identity formation, as social and cultural meaning seem to be at the root of involvement. Even though both men and women find great joy in the transmissions, their viewing is embedded in quite diverse patterns regarding additional media use. This points to gendered differences regarding how the entertaining experience is basically received and the qualities sought and pursued in the transmissions.

Technology Focus: EOR Performance and Modeling
Authors: Gurpinar Omer 
Published: February 2017

Technology Focus
Since the last time I wrote for this feature, enhanced-oil-recovery (EOR) activities around the world have been steadily increasing, meaning that the unusual crises our industry has been going through did not kill EOR. Instead, activities have expanded. For sure, current conditions have had some effect on how we see EOR, and, amazingly, with few exceptions, it has been positive. Current conditions have made most companies decide to optimize performance of their existing assets, and EOR is a key part of that. After all, optimizing is an ordinary ingredient of cost control. It is also worth adding that unconventional oil, which, for many, was the reason for the current crisis, is a big reason for the expansion of EOR. The unconventional producers are very keen on increasing recovery from their assets. Therefore, while enhancements on drilling and hydraulic fracturing will continue, it is expected that the next big wave will start when EOR becomes an integral part of unconventional development.
The EOR papers I have had the privilege to review this year truly support these observations regarding the state of the industry. Novel EOR schemes, advancements in reservoir characterization leading to better insights into the recovery processes, and new physics and modeling techniques all demonstrate the high level of interest in EOR among operators, academia, and research organizations.
In closing, I have to remind myself that we have been waterflooding since the 1930s and the fundamental EOR schemes (i.e., chemicals and CO2) have been with us since the late 1960s. Low-salinity and hybrid schemes have been growing during the past 10 years, and we are getting better at establishing conformance controls such as foams and thermally activated polymers. If we also add the inclusion of completions and EOR-specific monitoring technologies to the enablers, it is easy to anticipate that more and more EOR will be considered a normal part of field optimization.

Technology Focus: Well Integrity and Well Control
Authors: Alcantara Santos Otto Luiz 
Published: February 2017

Technology Focus
One of the more important aspects of well integrity during drilling operations is early kick detection. When an unintentional flow of the formation fluid into the wellbore occurs during conventional drilling operations, it must be detected promptly and the flow must be stopped, normally by closing the well. The early detection is crucial in minimizing the influx size. When the amount of formation fluid inside the well is large, especially if it is gas, the pressure inside the well will be higher during the subsequent well-control operations. This can lead to an increase in time to control the well or even to a worse situation: the loss of control. Another concern may be the amount of formation fluid to be handled at surface. Deepwater, high-pressure/high-temperature, and slimhole drilling are situations where early kick detection is mandatory.
The early kick detection is accomplished with a rig equipped with the appropriate kick-detection sensors and alarms and with a rig crew trained in quickly recognizing a kick and in the shut-in procedures. However, there are situations where early kick detection becomes more problematic—for example, when operating on a floating rig because of its motions, when using non-aqueous drilling fluids because of gas solubility, or during connections.
Recently, new technologies and research have been applied or developed to improve the kick-detection systems and to overcome some of the difficulties. To cite just a few examples,
Development of automated kick-detection systems (one of the papers summarized here addresses kick detection during connections)
Kick detection just above the bit using logging-while-drilling information
Kick detection using wired drillstring
Research on the effect on kick detection of gas solubility in nonaqueous drilling fluids (mineral oil, paraffin, ester, and olefins)
The use of managed-pressure-drilling systems (one of the papers recommended for additional reading comments on the advantage of this technology in reducing the kick size)

The Bone Regeneration Using Bone Marrow Stromal Cells with Moderate Concentration Platelet-Rich Plasma in Femoral Segmental Defect of Rats
Authors: Yamakawa Junichi , Hashimoto Junichi , Takano Mitsuo , Takagi Michiaki 
Published: February 2017

Background:Platelet-rich plasma (PRP) can provide an assortment of growth factors, but how PRP effects bone regeneration is still unknown. The aim of the study was to explore an optimal method of using PRP and bone marrow stromal cells (BMSCs).Methods:Anin vitroexperiment was first conducted to determine an appropriate quantity of PRP. BMSCs were cultured with PRP of different concentrations to assess cell proliferation and osteogenic differentiation. Following thein vitrostudy, a rat femoral segmental defect model was used. Five collagen mixtures consisting of different concentrations of PRP and BMSCs were prepared as follows, i) BMSCs and PRP (platelet 20 x 104/µl), ii) BMSCs and PRP (platelet 100 x 104/µl), iii) BMSCs and PRP (platelet 500 x 104/µl), iv) BMSCs, and v) PRP group (platelet 100 x 104/µl), were used to fill defect. New bone formation was evaluated by soft X-ray and histologic analyses were performed at 2, 4, 6 and 8 weeks postoperatively.Results:The cell proliferation increased PRP concentration-dependently. Cellular alkaline phosphatase activity was higher in moderate concentration than high or low concentration group’sin vitrostudy.In vivostudy, the bone fill percentage of newly formed bone in BMSCs and PRP (platelet 100 x 104/µl) was 46.9% at 8 weeks and increased significantly compared with other groups.Conclusion:BMSCs with moderate level of PRP significantly enhanced bone formation in comparison with BMSCs or PRP transplant in a rat femoral defect model.
Budget Adjustments and Spending Patterns: A Transaction-Cycle View
Authors: Chandra Akhilesh , Menon Nirup M. , Mishra Birendra K. (Barry) 
Published: February 2017

ABSTRACT
Organizational- and departmental-level budgeting suffer from various shortcomings, such as asymmetric ratcheting. In this regard, we theorize, and propose, budgeting at the transaction-cycle level for effective budget designs. The transaction-cycle level budget requires management justification for resource assignment to business processes, often spanning multiple departments. The transaction-cycle typology consists of five cycles: production, expenditure, financial, revenue, and human-resources. In order to distinguish among transaction cycles, we use their relative positions within the value chain and technology content in their business processes. As a proof-of-concept, we develop theoretical arguments for asymmetric ratcheting in operating budgets at the transaction-cycle level in hospitals, and empirically examine this phenomenon using longitudinal archival data. Our hypotheses examine budgetary responses to overspending and underspending variances in operating budgets for fixed and variable costs. Our findings suggest that a transaction cycle's position in the value chain and its technology content play a role in determining asymmetric ratcheting during budgeting. We discuss our contributions from the perspectives of theory and practice of accounting, budgeting, and accounting information systems.
“Global” Management Accounting Research: Some Reflections
Authors: Van der Stede Wim A. 
Published: February 2017

ABSTRACT
I start with some examples of global studies that compare and contrast “remedies” to management control and corporate governance issues across borders to expose the common tenet of such studies that “uniformity” of practices or regulations is “counter-productive” given national/cultural variations across countries. However, I critically evaluate this so-called “non-uniformity” prescription by considering the costs of local or situational adaptions. This naturally links with the “homogenizing” effects of globalization, where I ponder whether globalization might actually reduce the power of comparative studies across countries or regions, or whether, regardless, there remains great benefit to be had from studying “local” practices that can be theoretically generalized. I also offer some suggestions to help strengthen the design of comparative studies to try and maximize their (conceptual, if not econometric) power.

Abstract
This chapter provides guidance for how to think about the role that humans play in conducting analyses that include ML as part of the workflow. It introduces a stance towards ML as “intelligence augmentation” rather than “artificial intelligence” and articulates four key questions for an analyst to consider when setting up analysis. It also introduces computational grounded theory as an alternative to automation-focused applications of ML.
Introduction: Russia’s War in Ukraine and the “Shared Neighbourhood” in a Historical Context
Authors: Burmester Isabell 
Published: February 2025

Abstract
This chapter provides an introductory exploration of the historical context underlying the EU and Russian influence in their “shared neighbourhood”, particularly against the backdrop of Russia's invasion of Ukraine. It outlines the legacy of Russian/Soviet imperialism, which facilitated Russia's continued influence in the region post-imperialism, contrasted with the EU's use of its enlargement and neighbourhood policies to project its power. The chapter reviews pertinent literature, illustrating that conceptualisations of EU and Russian influence developed independently, particularly at the meso-level. It argues that the current conflict in Ukraine is embedded within a larger regional dynamic where EU and Russian influences intersect, shaped by historical, economic, and cultural legacies. The chapter emphasises the necessity of a historical perspective to comprehend contemporary EU and Russian influence, setting the stage for a systematic comparison of their respective hegemonic power mechanisms.
