Obtaining depth map from 2D non stereo images using deep neural networks
Authors: Mikhalchenko Daniil Igorevich , Ivin Arseniy , Malov Dmitrii 
Published: June 2018

PurposeSingle image depth prediction allows to extract depth information from a usual 2D image without usage of special sensors such as laser sensors, stereo cameras, etc. The purpose of this paper is to solve the problem of obtaining depth information from 2D image by applying deep neural networks (DNNs).Design/methodology/approachSeveral experiments and topologies are presented: DNN that uses three inputs—sequence of 2D images from videostream and DNN that uses only one input. However, there is no data set, that contains videostream and corresponding depth maps for every frame. So technique of creating data sets using the Blender software is presented in this work.FindingsDespite the problem of an insufficient amount of available data sets, the problem of overfitting was encountered. Although created models work on the data sets, they are still overfitted and cannot predict correct depth map for the random images, that were included into the data sets.Originality/valueExisting techniques of depth images creation are tested, using DNN.

Authors: Elliot Esi Abbam , Ngugi Benjamin , Malgwi Charles A. 
Published: June 2018

PurposeThe purpose of this paper is to investigate how technological innovations mitigate inefficiencies in marketing channels in the context of microfinance markets in emerging markets. By examining in detail, specific market inefficiencies that inhibit the efforts of micro and small enterprises to access microfinance in emerging markets and the use of technology to alleviate these failures, the authors bridge the literatures on marketing channel inefficiencies and technological innovation relevant to emerging markets.Design/methodology/approachThe authors use a qualitative method in the form of phenomenological interviews and participant observation in Ghana, West Africa, to investigate the research question.FindingsThe three themes that arise from the findings are: channel structure and structure selection; power-dependence relationships and relational outcomes; and conflict mechanisms and control behaviors. Customerization of technology is observed to mitigate inefficiencies in mobile marketing channels by facilitating data sharing, reminders, peer referencing and other marketing strategies of awareness, affordability, access and scalability.Research limitations/implicationsThe limitations of this study are the fact that the context of the study is only one emerging market country – Ghana. This market is however experiencing dynamic changes in mobile technology innovations that is revolutionizing the microfinance industry.Practical implicationsMobile money innovations have advanced the scope of marketing channels to the point that an updated perspective of the role of mobile technology in mitigating marketing channels inefficiency is both appropriate and timely.Originality/valueThe authors make the contribution of customerization as an aspect of mobile technology that is a key enabler in microfinance marketing channels, serving to mitigate microfinance market inefficiencies. Additionally, the study augments theories on the marketing channels framework by contributing perspectives on mobile technology.
A flexible self-adaptive underactuated hand with series passive joints
Authors: Luo Chao , Zhang Wenzeng 
Published: June 2018

Purpose
This paper aims to propose a novel hand to bridge the gap between the traditional rigid robot hands and the soft hands to obtain a better grasping performance.

Design/methodology/approach
The proposed hand consists of three fingers. Each finger has 15 degrees of freedom and three phalanxes, which can bend in one direction when load is applied, but they are rigid toward the opposite direction at the initial position. The grasping process and simulations of the fingers are discussed in this paper. Both kinematic and dynamics analyses are performed to predict the performance of the hand. Subsequently, a prototype of the hand is developed for experiments.

Findings
Both kinematics and dynamics analyses indicate good grasping performance of the hand. Simulations and experiments confirm the feasibility of the finger design. The hand can execute hybrid grasping modes with more uniform force distribution and a larger workspace than traditional rigid fingers. The proposed hand has much potential in the industrial sector.

Originality/value
A new method to obtain better grasping performance and to bridge the gap between the rigid finger and the soft finger has been presented and verified. The hand combines the advantages of both the rigid phalanxes and the soft fingers. Compared with some traditional rigid fingers, the proposed design has a more uniform force distribution and a bigger workspace.
Limits to psychological ownership in the family business
Authors: Broekaert Wouter , Henssen Bart , Lambrecht Johan , Debackere Koenraad , Andries Petra 
Published: June 2018

Purpose
The purpose of this paper is to analyze how the sense of control, psychological ownership and motivation of both family owners and non-family managers in family firms are interrelated. This paper analyzes the limits set by family owners when delegating control to their non-family managers and the resulting potential for conflict and demotivation of the non-family managers.

Design/methodology/approach
Building on the existing literature, first, an overview of the literature on psychological ownership and control is presented. Second, the paper analyzes the insights gained from interviews with 15 family owners and non-family managers in five family firms.

Findings
This study finds that motivating non-family managers is not merely a matter of promoting a sense of psychological ownership throughout the company. A strong sense of psychological ownership may facilitate but also hinder the cooperation between family and non-family. Family owners are often only willing to delegate operational control, while non-family managers also feel entitled to participate in strategic decision making. This leads to the proposition that non-family managers’ psychological ownership in family firms’ conflicts with family owners’ desire to maintain control.

Originality/value
This study answers the calls to seek additional insight in how non-family managers function within family firms. By shedding light on the complex relationship between control, psychological ownership and motivation in family firms, the study responds to the calls for more empirical validation of the psychological ownership framework and for more research into the potential negative effects of psychological ownership in the family business.
The effect of revenue diversification and form of government on public spending
Authors: Park Ji Hyung , Park Sungho 
Published: June 2018

PurposeRevenue diversification interacting with form of government that has different management behaviors may produce a variation in the level of public spending. The purpose of this paper is to understand how revenue diversification interacts with form of government in determining the level of public spending.Design/methodology/approachA cross-sectional research design with the analysis of interaction effects was employed in order to achieve this research objective. Drawing from the economic and financial management perspectives on revenue diversification, this study proposes the following hypotheses: in the council-manager form, greater revenue diversification leads to less spending; in the mayor-council form, greater revenue diversification leads to more spending; and mayor-council governments with diversified revenues spend more than council-manager governments.FindingsThe regression results support the second and third hypotheses, but not the first hypothesis.Originality/valueThis study offers a robust link between revenue diversification and form of government by examining how their interaction produces a variation in the level of public spending.
Beyond new roads and bridges
Authors: O’Connell Lenahan , (Wie) Yusuf Juita-Elena , Anuar Khairul Azfi 
Published: June 2018

Purpose
The purpose of this paper is to compare public preferences for investment and spending on non-automobile infrastructures (mass transit and bicycling) to preferences for new roads and the repair of current highways. The study explores the factors that explain preferences for non-automobile infrastructure using a three-factor model including self-interest (personal transportation benefits), concern for community-wide benefits (political beliefs), and concern for the economic impact. The study uses a case study of the urban context of the Hampton Roads region of Southeastern Virginia (USA).

Design/methodology/approach
The analysis uses data from a 2013 telephone survey of urban residents in the Hampton Roads area. Survey respondents were asked to identify their two investment priorities from four options: repairing existing roads, bridges, and tunnels; constructing new or expanding roads, bridges, and tunnels; expanding mass transit; and expanding bicycle routes and improving bike safety.

Findings
Repairing existing highway infrastructure is the most popular spending priority (66 percent of residents). There is as much support (46 percent) for investing in non-automobile infrastructure as for investing in new roads, bridges, and tunnels. Significant predictors of support for non-automobile infrastructure, using the three-factor model, are: length of commute time, self-identification as liberal, use of light rail, and a belief that light rail contributes to economic development.

Originality/value
The study examines public preferences for both non-traditional and traditional transportation infrastructure investments. It highlights the factors that contribute to public support for different transportation spending options.

Tableau Public is a free tool that libraries can use to visualize their data.

Design/methodology/approach
This paper gives an overview of Tableau Public and discusses best practices for using it in library services.

Findings
Tableau Public is a free-to-use downloadable software that enables librarians with no data science expertise to build beautiful and interactive data visualizations, which can be shared with staff, administration and other stakeholders.

Originality/value
This paper should be of use to any librarians interested in finding new and effective ways of communicating their library statistics. Tableau Public can be used to visualize data from a variety of library departments, including circulation, reference, instruction and collection management.
Politics, culture and M&As’ transaction completion
Authors: Li Shi , Huang Shizhong 
Published: June 2018

Purpose
Mergers and acquisitions (M&As) dominated by Chinese enterprises have become increasingly conspicuous and prevalent in recent years. However, many of them were obstructed by foreign governments on the ground of “Threating National Security”. Overseas acquisition is a crucial step of Chinese Government’s “Going-Out” strategy, so analyzing the attribution of its success and failure is very important.

Design/methodology/approach
This paper adopts empirical study method to analyze the factors from political and cultural perspectives based on a sample of 327 cross-border M&A transactions made by all listed companies in China from 1997 to 2010.

Findings
The result shows higher failure rate for those acquisition targets which could be classified as political sensitive assets; meanwhile, positive diplomatic relations and higher bilateral trust between China and the host country will facilitate the M&A transaction.

Originality/value
This paper offers a new research angle on cross-border M&As, which is the impact of culture factors, as well as diplomatic relationship, bilateral trust and war history between China and the host country on M&A transactions. This paper also constructs several ways of measuring the diplomatic relationship between countries.
An interlocking and interdependent ecology
Authors: Kuglitsch Rebecca Zuege 
Published: June 2018

Purpose
This study aims to explore the potential areas of overlap and reinforcement between critical science literacy and information literacy. As an awareness of the limitations of traditional definitions of scientific literacy and traditional science instruction has grown, there is an opportunity to apply a critical lens to science and IL.

Design/methodology/approach
The paper examines the literature of critical scientific literacy and connects it to information literacy practices.

Findings
There is considerable room for librarians to foster and support critical scientific literacy in parallel with information literacy. Both literacies align significantly.

Practical implications
IL for students in the sciences can and should take a more critical approach to instruction to support scientific literacy as well as ILI.

Originality/value
Traditional science literacy has had relatively limited impact perhaps, but critical science literacy offers a way to construct science literacy as a meaningful engagement; combining it with critical approaches to information literacy offers the opportunity to reinforce both skills.
The Extraction and Recovery Efficiency of Pure DNA for Different Types of Swabs
Authors: Bruijns Brigitte B. , Tiggelaar Roald M. , Gardeniers Han 
Published: June 2018

AbstractThe extraction and recovery efficiency of swabs used to collect evidence at crime scenes is relatively low (typically <50%) for bacterial spores and body fluids. Cell‐free deoxyribonucleic acid (DNA) is an interesting alternative compared to whole cells as a source for forensic analysis, but extraction and recovery from swabs has not been tested before using pure DNA. In this study cotton, foam, nylon flocked, polyester and rayon swabs are investigated in order to collect pure DNA isolated from saliva samples. The morphology and absorption capacity of swabs is studied. Extraction and recovery efficiencies are determined and compared to the maximum theoretical efficiency. The results indicate that a substantial part of DNA is not extracted from the swab and some types of swab seem to bind effectively with DNA. The efficiency of the different types of swab never exceeds 50%. The nylon flocked 4N6FLOQSwab used for buccal sampling performs the best.
Juvenile hormone signaling – a mini review
Authors: Li Kang , Jia Qiang‐Qiang , Li Sheng 
Published: June 2018

AbstractSince it was first postulated by Wigglesworth in 1934, juvenile hormone (JH) is considered a status quo hormone in insects because it prevents metamorphosis that is initiated by the molting hormone 20‐hydroxyecdysone (20E). During the last decade, significant advances have been made regarding JH signaling. First, the bHLH‐PAS transcription factor Met/Gce was identified as the JH intracellular receptor. In the presence of JH, with the assistance of Hsp83, and through physical association with a bHLH‐PAS transcriptional co‐activator, Met/Gce enters the nucleus and binds to E‐box‐like motifs in promoter regions of JH primary‐response genes for inducing gene expression. Second, the zinc finger transcription factor Kr‐h1 was identified as the anti‐metamorphic factor which transduces JH signaling. Via Kr‐h1 binding sites, Kr‐h1 represses expression of 20E primary‐response genes (i.e. Br, E93 and E75) to prevent 20E‐induced metamorphosis. Third, through the intracellular signaling, JH promotes different aspects of female reproduction. Nevertheless, this action varies greatly from species to species. Last, a hypothetical JH membrane receptor has been predicted to be either a GPCR or a tyrosine kinase receptor. In future, it will be a great challenge to understand how the JH intracellular receptor Met/Gce and the yet unidentified JH membrane receptor coordinate to regulate metamorphosis and reproduction in insects.
Late development of hepatocellular carcinoma after viral clearance in patients with chronic hepatitis C: A need for continual surveillance
Authors: Tong Myron J , Theodoro Carmem F , Salvo Rebecca T 
Published: June 2018

OBJECTIVEEradication of chronic hepatitis C (CHC) infection decreases the incidence of hepatocellular carcinoma (HCC), but a risk remains. We aimed to investigate HCC development‐associated factors in CHC patients with sustained virological response (SVR) after antiviral therapies.METHODSWe compared CHC patients achieving SVR from 1996–2016 who did and did not develop HCC. Their median follow‐up period was 8.01 years.RESULTSCompared with 164 non‐HCC SVR patients, 22 who developed HCC were older at SVR (P = 0.032), had a higher incidence of diabetes (P = 0.013) and higher pre‐antiviral treatment alpha‐fetoprotein (AFP) levels (P = 0.016), more had fibrosis stage 3 and cirrhosis (P = 0.0009) and hepatitis B core antibody (anti‐HBc) positivity (P = 0.006). Eight and seven of 22 patients, respectively, developed HCC at 4–10 years and 10 years after SVR. The longest duration from SVR to HCC was 18.7 years. Independent factors associated with HCC development were anti‐HBc positivity (hazard ratio [HR] 5.57, P = 0.012), age at SVR (HR 1.08, P = 0.014), higher pre‐antiviral treatment AFP levels (HR 1.01, P = 0.01) and Hispanic ethnicity (HR 12.9, P = 0.002). HCC risk was significantly less in genotype 2 patients (HR 0.2, P = 0.02) or in those with higher pre‐antiviral treatment albumin levels (HR 0.33, P = 0.04).CONCLUSIONSThe risk for HCC exists in a subset of CHC patients after SVR and may occur up to 18 years after viral clearance. Indefinite HCC surveillance is necessary in SVR patients with other risk factors.
Integrating Temporal Inequality into Conservation Planning to Improve Practice Design and Efficacy
Authors: Williams Mark R. , King Kevin W. , Penn Chad J. 
Published: June 2018

AbstractIn contrast to spatial inequality, there are currently no methods for leveraging information on temporal inequality to improve conservation efficacy. The objective of this study was to use Lorenz curves to quantify temporal inequality in surface runoff and tile drainage, identify controls on nutrient loading in these flowpaths, and develop design flows for structural conservation practices. Surface runoff (n = 94 site‐years) and tile drainage (n = 90 site‐years) were monitored on 40 fields in Ohio. Results showed, on average, 80% of nitrate‐nitrogen, soluble reactive phosphorus (P), and total P loads occurred between 7 and 12 days per year in surface runoff and between 32 and 58 days per year in tile drainage. Similar temporal inequality between discharge and load provided evidence that loading was transport‐limited and highlighted the critical role hydrologic connectivity plays in nutrient delivery from tile‐drained fields. Design flow criterion for sizing structural practices based on load reduction goals was developed by combining Lorenz curves and flow duration curves. Comparing temporal inequality between fields and the Maumee River, the largest tributary to the western Lake Erie Basin, revealed challenges associated with achieving watershed load reduction goals with field‐scale conservation. In‐field (i.e., improved nutrient and water management), edge‐of‐field (i.e., structural practices), and instream practices will all be required to meet nutrient reduction goals from tile‐drained watersheds.
ATHLETICS, MEMORY, AND COMMUNITY IN HELLENISTIC AND ROMAN MESSENE
Authors: PAPAKONSTANTINOU ZINON 
Published: June 2018

AbstractRecent excavations in the site of Messene have unveiled numerous inscriptions from the Hellenistic and Roman imperial periods that significantly increase our understanding of the agonistic life of the city. By utilizing this new set of evidence in this paper I examine patterns of athletic competition by Messenian athletes in panhellenic and local contests. Moreover, I explore victory commemoration practices in the urban landscape of Messene as a means to comprehend how the community acted out, in an institutionalized manner, its collective memory, identity, and historical consciousness.
ARMORUM STUDIUM: GLADIATORIAL TRAINING AND THE GLADIATORIAL LUDUS
Authors: CARTER MICHAEL 
Published: June 2018

AbstractIn his Apologia (98.7), written about ad 158, Apuleius laments the fact that his former ward, the noble young Sicinius Pudens, has been allowed to abandon his studies and is instead spending his time in taverns and with prostitutes and, worst of all, has become a frequent visitor at the local gladiatorial school. Pudens has come to know all the gladiators’ names, their ‘fights and wounds’, and has even started receiving instruction from the lanista himself. In this paper, I investigate the possible reasons why aristocratic Roman youth (iuvenes) might have sought weapons-training and the means by which these young men could have accessed such training in connection with a gladiatorial ludus. The investigation additionally considers the organization of gladiators and their trainers in the ludus.
