Discussion on “Quantifying Publication Bias in Meta‐Analysis” by Lin and Chu

Publication bias is an important consideration when metaanalysis is undertaken (Light and Pillemer, 1984; Moher et al., 2009; Haidich, 2010). A number of methods to assess publication bias in meta-analysis have been developed in the past and include funnel plot assessment and selection methods. Briefly, the funnel plot shows the relative risk or log odds ratio on the x-axis and a measure of study precision, such as the study size itself, or the inverse squared error of the effect size on the y-axis. A regression test of funnel plot asymmetry was proposed by Egger et al. (1997). They demonstrated that of eight meta-analyses which were discordant with single large trials, three of four discordant pairs showed funnel plot asymmetry. Begg and Mazumdar (1994) proposed an adjusted rank correlation test and noted that the test is fairly powerful with 75 component studies, but has low power with 25 component studies. Selection methods (Hedges and Vevea, 2005) weight studies to adjust the overall effect size based on uncheckable assumptions (McShane, Bockenholt and Hansen, 2016) and thus are usually used for sensitivity analysis (Lin and Chu, 2017). New and better methods are sorely needed. In this issue, Lin and Chu (2017) propose a new test for publication bias using skewness of the standardized deviates to test for publication bias and develop its asymptotic theory. They also provide an estimate and 95% confidence interval for publication bias. Although large sample theory does not work well with a small number of studies, they propose the nonparametric bootstrap to construct a 95% confidence interval. Their new method has high power in many scenarios. A further issue in assessing publication bias was raised by Tang and Liu (2000). Using 198 meta-analyses from the Cochrane database, they used Egger’s test and noted that the funnel plot can change from symmetric to asymmetric or vice versa, or asymmetry can actually be reversed, depending on the scale of the y-axis. They found 34% of meta-analyses had inconsistent funnel plots depending on how the plot was constructed. They concluded that all asymmetric funnel plots depend on the way the plot is constructed. Their discussion raises the question of whether the funnel plot is valid as a method of detecting publication bias. Thus, we recommend that when using Lin and Chu’s method, meta-analysts consider different scales for the funnel plot as part of the meta-analysis protocol. It would be interesting to see if Lin and Chu’s method can yield different results depending on the chosen scale. What would one do then? It is clear further work is needed on detection of publication bias for meta-analysis. We congratulate the authors on their new proposal and look forward to further developments.
Museumpark Revisit: A Data Mining Approach in the Context of Hong Kong

It is important for tourism managers to understand the synergistic effects between museums in tourism management. This study raises is concerned with the "museumpark" and re-examines the synergistic effects among museums in Hong Kong. Utilising online photos from social media, over 2500 photos from more than 300 visitors were collected and analysed quantitatively. Through limited dependent variable regressions, the results show that once a visitor visits one museum in the "museumpark", the probability that this visitor will visit another museum nearby increase significantly. Based on the result of this study, museum researchers can further investigate the precise synergistic effects between museums.
Multi-input DC boost converter for grid connected hybrid PV/FC/Battery power system

This paper proposes a new multi-input dc boost converter for grid-connected hybrid Photovoltaic (PV)/Fuel cell (FC)/Battery power system, supplying a residential load. In this structure each switching cycle of proposed boost converter is divided in to five switching periods in comparison with conventional structure. These switching periods introduce five different duty ratios for the proposed boost converter. With utilizing these duty ratios, extracting maximum available PV power, setting FC operation power on optimal range and charging/discharging of battery is possible. For achieving these goals, participation factor of hybrid system (G) is defined to manage the system power flow. Considering the FC optimal operation range, power of PV array and load, different operating modes of system are analyzed. The proposed system has been simulated by PSCAD/EMTDC linked to MATLAB software for different operating modes. The simulation results have shown the performance of the novel structure with desired features.

We allow the confirmation of the verification that can be obtained about the D-ORCD value. In fact, we reflect the D-ORCD capabilities that require a D-ORCD change in a specific way.
Modeling Modern Code Review Practices in Open Source Software Development Organizations

Many Open Source Software (OSS) communities has adopted peer code review as an effective quality improvement practice. The informal, regular, and tool-based code review process has been called ’modern code review’. There has not been much research on the modern code review process. This dissertation aims to model the this code review process adopted by the software organizations through 1)understanding, 2) improving, and 3) providing suggestions. I have planned seven steps to achieve the research goal, which includes literature review, exploring OSS code review practices, mining OSS code review repositories, comparing code review metrics across projects, surveying OSS code review participants, analyzing the effectiveness of peer code reviews to prevent security vulnerabilities, and social network analysis. So far, I have completed first three steps and made significant progress towards the next three steps. The research has contributed an empirical evidence that code review helps building accurate peer impressions between the code review participants. The planned future contributions include providing effective strategies to perform peer code review, evaluating the effectiveness of peer code review to prevent security vulnerabilities, and influence of project characteristics /social network structure on the peer code review process.
Corporate Governance in an MNC: Towardsthe View of Culturally Determined Agency

This study is positioned to contribute to the subject area of corporate governance in multi-national corporations (MNCs), which represents a substantial void in the literature both on corporate governance and international business. The new theoretical proposition of culturally determined agency is suggested. It builds on the recently put forward behavioural theory of corporate governance. This novel theoretical lens in corporate governance merges the under-socialized agency theory, as the dominant institutional logic in corporate governance of domestic firms, and the behavioural theory of the firm, which is probably the only theory of the firm that explicitly treats firms as complex social systems. Finally, three exemplifications of application of this new theoretical construct of culturally determined agency to the analysis of contemporaneous business issues in MNCs are briefly discussed: meta-national governance, use of expatriates, as well as knowledge and innovation management.
Constant and variable aspects of the dichotic listening right-ear advantage: A comparison of standard and signal detection tasks

The study was designed to disentangle perceptual and attentional components of the dichotic listening right-ear advantage (REA). A total of 120 normal adults (108 right-handers and 12 left-handers) were administered the Halwes Fused Dichotic Words Test (FDWT) under standard conditions, which entail a forced-choice response format and no attention instructions. Two weeks later, the same stimuli were administered in a signal detection format with varied attention instructions (left, right, and equally divided). The standard task yielded the expected REA. The signal detection task yielded an REA for detection of targets that remained invariant across attention conditions. In contrast, ear asymmetry for localisation of targets varied with attention instructions. The REA on the standard task was correlated with the asymmetry of target detection (r = .57) on the signal detection task but not with the asymmetry of localisation or response bias. Ear asymmetry on the standard test seems to reflect an early stage of processing that is not altered by shifts of attention. Volitional shifts of attention influence the localisation of targets, but this component of signal processing is unrelated to the REA obtained on the standard test.
Etude des résonances morphologiquement dépendantes et application à la caractérisation de microparticules en milieu diphasique

Le travail realise au cours de cette these visait l'etude d'un phenomene particulier propre aux particules micrometriques de forme spherique : les Resonances Morphologiquement Dependantes (MDR) qui se manifestent sous la forme de pics d'intensite dans les spectres de diffusion. Leur etude complete a permis le developpement d'un algorithme d'exploitation base sur la theorie de Mie. Son utilisation dans une campagne experimentale reposant sur l'extraction de spectres de fluorescence a demontre une reelle capacite des MDR pour la mesure fine du diametre. La determinantion de l'indice de refraction s'est revelee cependant moins satisfaisante avec une precision situee entre la deuxieme et la troisieme decimales pour une resolution de 0. 3 A, ce qui n'a pas empeche l'evaluation de gradients radiaux d'indice au niveau de la quatrieme decimale. L'ensemble de ces resultats laisse entrevoir de nombreuses applications comme la mesure de taux d'evaporation instantanes.
An Empirical Study on Investment Factors of Information Security Based on UTAUT

Recently, new security risks are increasing as companies introduce new services such as mobile, Cloud, Big Data and IoT, which are core technologies of the 4th industrial revolution. The security environments of Korean companies are a low level of security organization, budgets, so security investments are urgent to cope with new security risks of new services. We analyze investment factors on information security and suggest policies to improve security levels through security investments. In this paper, we design a research model based on UTAUT and protection motivation theory, consisting of assets, concerns (threats and vulnerability), experience and habits, social influences, facilitation conditions. For the empirical analysis, data from the survey of information security were used and the structural equation model was analyzed. The results of analysis shows that security investments have more influence on internal factors (assets, facilitation conditions, experience and habits) rather than external threats.
Analysis of individual items on the attention-deficit/hyperactivity disorder symptom rating scale in children and adults: the effects of age and sex in pivotal trials of lisdexamfetamine dimesylate

Background Attention-deficit/hyperactivity disorder (ADHD) symptom presentation across age and sex has not been fully elucidated. The present post hoc analyses qualitatively explored the baseline levels of ADHD symptomatology across subgroups in two clinical trials of children and adults with ADHD to elucidate differences in participant presentation. The response to treatment was examined to determine patterns of response among items of the ADHD Rating Scale IV. Methods Exploratory post hoc analyses of ADHD Rating Scale IV item scores were conducted on data from two 4-week placebo-controlled trials in children (6–12 years) and in adults (18–55 years) with ADHD. Baseline and endpoint mean item scores were determined for subgroups defined by age (6–9, 10–12, 18–39, and 40–55 years) and sex. Results The baseline mean item scores were generally numerically similar for all age-by-sex subgroups. The inattention (IA) items were numerically higher than hyperactivity/impulsivity (H/I) items among older children and adults. The endpoint mean item scores were numerically lower after lisdexamfetamine dimesylate treatment for IA and H/I items in all subgroups. Conclusion These results suggest that regardless of age or sex, baseline IA and H/I symptom profiles were comparable; however, IA vs H/I symptoms were more severe in older participants. In all age-by-sex subgroups, IA and H/I symptoms appeared to decrease after active treatment.
Near-field microscope probe for far infrared time domain measurements

A near-field probe fabrication technique for far-infrared frequencies based on photoconducting antennas is developed. A subwavelength-size field source is accomplished by means of an aperture and protruding high refractive index tip. The near-field probe is tested by using free space traveling electromagnetic pulses with a broadband spectrum in the range of 0.3‐1.5 THz. A spatial resolution of 60 mm is achieved for a 50 mm aperture. The described probe may be used for near-field transmission microscopy in illumination and collection modes. Resolution may be further improved by means of a smaller aperture. © 2000 American Institute of Physics. @S0003-6951~00! 04630-1#
Aging impairs intermediate-term behavioral memory by disrupting the dorsal paired medial neuron memory trace

How the functional activity of the brain is altered during aging to cause age-related memory impairments is unknown. We used functional cellular imaging to monitor two different calcium-based memory traces that underlie olfactory classical conditioning in young and aged Drosophila. Functional imaging of neural activity in the processes of the dorsal paired medial (DPM) and mushroom body neurons revealed that the capacity to form an intermediate-term memory (ITM) trace in the DPM neurons after learning is lost with age, whereas the capacity to form a short-term memory trace in the α′/β′ mushroom body neurons remains unaffected by age. Stimulation of the DPM neurons by activation of a temperature-sensitive cation channel between acquisition and retrieval enhanced ITM in aged but not young flies. These data indicate that the functional state of the DPM neurons is selectively altered with age to cause an age-related impairment of ITM, and demonstrate that altering the excitability of DPM neurons can restore age-related memory impairments.
Automated detection of cars in transmission X-ray images of freight containers

We present a method for automated car detection in xraytransmission images of freight containers. A random forest classifier was used to classify image sub-windows as “car” and “non-car” based on image features such as intensity and log-intensity, as well as local structures and symmetries as encoded by Basic Image Features (BIFs) and oriented Basic Image Features (oBIFs). The proposed approach was validated using a dataset of stream of commerce X-ray images. A car detection rate of 100% was achieved while maintaining a false alarm rate of 1.23%. Further reduction in false alarm rate, potentially at the cost of detection rate, was possible by tweaking the classification confidence threshold. This work establishes a framework for the automated classification of X-ray transmission cargo images and their content, paving the way towards the development of tools to assist custom officers faced with an ever increasing number of images to inspect.
Semantic Document Annotation Ranking Model

With the support of semantic annotation and domain ontology, semantic web is able to assist people in querying rich documents. However, generating queried semantic documents without ranking them in a right order is ineffective. In this paper, we are extending FF-ICF algorithm with the concept spreading. For experimentation, this algorithm is applied into a research prototype retrieval engine, PicoDoc. The PicoDoc system uses corpus that has pre-annotated documents as its data reference to run query against, based on real-life dataset from ABC and BBC news article corpus. The corpus is based on OCAS2008 ontology. The experiment shows a modified FFICF-related spread concept yields promising results in retrieving related information.

The impact of atmospherics on WOM about short life-cycle products: the case of motion pictures

Purpose This paper aims to empirically examine how atmospherics affect word of mouth (WOM) about the brand. The authors focus primarily on uncovering the causal mechanism in which such effect is serially mediated by both perceived positive emotions evoked by atmospherics and attitude toward the brand. Design/methodology/approach To test the research hypotheses, 314 Greek moviegoers were drafted to participate in a survey. Data were analysed using confirmatory factor analysis (AMOS) and the SPSS macro (PROCESS tool). The model was applied to motion pictures, as they provide a particularly good example of short life-cycle products. Findings Findings indicate that atmospherics are related to WOM about the brand through perceived emotions evoked by atmospherics and, in turn, attitude toward the brand. Research limitations/implications The present study extends the relevant literature by providing both direct and indirect links between atmospherics and WOM about a brand. Practical implications The model of the present study could be applied to other short life-cycle products that share key characteristics with motion pictures. Moreover, the present study increases movie producers and exhibitors’ understanding of the effects of theatre atmospherics on WOM about the movie and leads to practical suggestions and implications. Originality/value WOM is one of the key variables that can affect the profitability of short life-cycle products. To date, there was no evidence that atmospherics can influence WOM about a short life-cycle product.
Efficient Fine-Grained Location Prediction Based on User Mobility Pattern in LBSNs

Location-Based Social Networks (LBSNs) have built bridges between virtual space and real-world mobility in recent years. The massive check-in data generated in LBSNs has made it possible to predict users' future check-in location, which has proved meaningful for e-commerce developments. Existing studies mainly focus on predicting the next check-in location with a coarse granularity, which shows limited performance in practical scenarios. In this paper, we propose a comprehensive approach based on user mobility pattern for predicting users' future check-in location at any fine-grained time in LBSNs. Firstly, user mobility patterns involving time periodicity, global popularity and user preference are analyzed. Then, a set of predictive features are extracted. Finally, the features are combined into a supervised scoring model and a classification model respectively in order to predict users' future check-in location. Extensive experiments on three real-world datasets demonstrate the efficiency and superiority of the proposed approach in various metrics.
Constitutive CD40L Expression on B Cells Prematurely Terminates Germinal Center Response and Leads to Augmented Plasma Cell Production in T Cell Areas

CD40/CD40L engagement is essential to T cell-dependent B cell proliferation and differentiation. However, the precise role of CD40 signaling through cognate T–B interaction in the generation of germinal center and memory B cells is still incompletely understood. To address this issue, a B cell-specific CD40L transgene (CD40LBTg) was introduced into mice with B cell-restricted MHC class II deficiency. Using this mouse model, we show that constitutive CD40L expression on B cells alone could not induce germinal center differentiation of MHC class II-deficient B cells after immunization with T cell-dependent Ag. Thus, some other MHC class II-dependent T cell-derived signals are essential for the generation of germinal center B cells in response to T cell-dependent Ag. In fact, CD40LBTg mice generated a complex Ag-specific IgG1 response, which was greatly enhanced in early, but reduced in late, primary response compared with control mice. We also found that the frequency of Ag-specific germinal center B cells in CD40LBTg mice was abruptly reduced 1 wk after immunization. As a result, the numbers of Ag-specific IgG1 long-lived plasma cells and memory B cells were reduced. By histology, large numbers of Ag-specific plasma cells were found in T cell areas adjacent to Ag-specific germinal centers of CD40LBTg mice, temporarily during the second week of primary response. These results indicate that CD40L expression on B cells prematurely terminated their ongoing germinal center response and produced plasma cells. Our results support the notion that CD40 signaling is an active termination signal for germinal center reaction.
