The impact of cerebellar transcranial direct current stimulation (tDCS) on learning fine-motor sequences
Authors: Shimizu Renee E. , Wu Allan D. , Samra Jasmine K. , Knowlton Barbara J. 
Published: November 2016

The cerebellum has been shown to be important for skill learning, including the learning of motor sequences. We investigated whether cerebellar transcranial direct current stimulation (tDCS) would enhance learning of fine motor sequences. Because the ability to generalize or transfer to novel task variations or circumstances is a crucial goal of real world training, we also examined the effect of tDCS on performance of novel sequences after training. In Study 1, participants received either anodal, cathodal or sham stimulation while simultaneously practising three eight-element key press sequences in a non-repeating, interleaved order. Immediately after sequence practice with concurrent tDCS, a transfer session was given in which participants practised three interleaved novel sequences. No stimulation was given during transfer. An inhibitory effect of cathodal tDCS was found during practice, such that the rate of learning was slowed in comparison to the anodal and sham groups. In Study 2, participants received anodal or sham stimulation and a 24 h delay was added between the practice and transfer sessions to reduce mental fatigue. Although this consolidation period benefitted subsequent transfer for both tDCS groups, anodal tDCS enhanced transfer performance. Together, these studies demonstrate polarity-specific effects on fine motor sequence learning and generalization.This article is part of the themed issue ‘New frontiers for statistical learning in the cognitive sciences’.
Statistical learning in songbirds: from self-tutoring to song culture

Published: November 2016

At the onset of vocal development, both songbirds and humans produce variable vocal babbling with broadly distributed acoustic features. Over development, these vocalizations differentiate into the well-defined, categorical signals that characterize adult vocal behaviour. A broadly distributed signal is ideal for vocal exploration, that is, for matching vocal production to the statistics of the sensory input. The developmental transition to categorical signals is a gradual process during which the vocal output becomes differentiated and stable. But does it require categorical input? We trained juvenile zebra finches with playbacks of their own developing song, produced just a few moments earlier, updated continuously over development. Although the vocalizations of these self-tutored (ST) birds were initially broadly distributed, birds quickly developed categorical signals, as fast as birds that were trained with a categorical, adult song template. By contrast, siblings of those birds that received no training (isolates) developed phonological categories much more slowly and never reached the same level of category differentiation as their ST brothers. Therefore, instead of simply mirroring the statistical properties of their sensory input, songbirds actively transform it into distinct categories. We suggest that the early self-generation of phonological categories facilitates the establishment of vocal culture by making the song easier to transmit at the micro level, while promoting stability of shared vocabulary at the group level over generations.

Ubiquity and quantitative significance of bacterioplankton lineages inhabiting the oxygenated hypolimnion of deep freshwater lakes
Authors: Okazaki Yusuke , Fujinaga Shohei , Tanaka Atsushi , Kohzu Ayato , Oyagi Hideo , Nakano Shin-ichi 
Published: November 2016

ABSTRACTFreshwater bacterioplankton in the oxygenated hypolimnion are reportedly dominated by specific members that are distinct from those in the epilimnion. However, no consensus exists regarding the ubiquity and abundance of these bacterioplankton, which is necessary to evaluate their ecological importance. The present study investigated the bacterioplankton community in the oxygenated hypolimnia of 10 deep freshwater lakes. Despite the broad geochemical characteristics of the lakes, 16S rRNA gene sequencing demonstrated that many predominant lineages in the hypolimnion were shared by several lakes and consisted of members occurring in the entire water layer and members specific to the hypolimnion. Catalyzed reporter deposition fluorescencein situhybridization (CARD-FISH) revealed that representative hypolimnion-specific lineages, CL500–11 (Chloroflexi), CL500–3, CL500–37, CL500–15 (Planctomycetes), and the MGI group (Thaumarchaeota), together accounted for 1.5–32.9% of all bacterioplankton in the hypolimnion of the lakes. Furthermore, an analysis of micro-diversification based on single-nucleotide variation in the partial 16S rRNA gene sequence (oligotyping) suggested the presence of hypolimnion-specific ecotypes among the lineages occurring in the entire water layer (e.g., acI andLimnohabitans). Collectively, these results demonstrate the uniqueness, ubiquity, and quantitative significance of bacterioplankton in the oxygenated hypolimnion, motivating future studies to focus on their eco-physiological characteristics.
ConfocalGN: a minimalistic confocal image simulator
Authors: Dmitrieff Serge , Nédélec François 
Published: November 2016

SummaryWe developed a user-friendly software to generate synthetic confocal microscopy images from a ground truth specified as a 3D bitmap with pixels of arbitrary size. The software can analyze a real confocal stack to derivate noise parameters and will use them directly to generate new images with similar noise characteristics. Such synthetic images can then be used to assert the quality and robustness of an image analysis pipeline, as well as be used to train machine-learning image analysis procedures. We illustrate the approach with closed curves corresponding to the microtubule ring present in blood platelets.Availability and implementationConfocalGN is written in MATLAB but does not require any toolbox. The source code is distributed under the GPL 3.0 licence onhttps://github.com/SergeDmi/ConfocalGN.
HiC-Spector: A matrix library for spectral and reproducibility analysis of Hi-C contact maps
Authors: Yan Koon-Kiu , Yardimci Galip Guürkan , Noble William S. , Gerstein Mark 
Published: November 2016

AbstractSummaryGenome-wide proximity ligation based assays like Hi-C have opened a window to the 3D organization of the genome. In so doing, they present data structures that are different from conventional 1D signal tracks. To exploit the 2D nature of Hi-C contact maps, matrix techniques like spectral analysis are particularly useful. Here, we present HiC-spector, a collection of matrix-related functions for analyzing Hi-C contact maps. In particular, we introduce a novel reproducibility metric for quantifying the similarity between contact maps based on spectral decomposition. The metric successfully separates contact maps mapped from Hi-C data coming from biological replicates, pseudo-replicates and different cell types.AvailabilitySource code in Julia and the documentation of HiC-spector can be freely obtained athttps://github.com/gersteinlab/HiC_spectorContactpi@gersteinlab.org
Career control, career dialogue and managerial position
Authors: Veld Monique , Semeijn Judith H. , van Vuuren Tinka 
Published: November 2016

Purpose
The purpose of this paper is to examine three-way interactions among career control, career dialogue and managerial position in predicting perceived employability. The authors expected that participation in career dialogue strengthens the positive relationship between career control and employability. Furthermore, the authors expected that managers benefit more from career dialogue than employees. Hence, the relationship between career control and employability was expected to be strongest when employees engage in career dialogue and hold a managerial position.

Design/methodology/approach
Data were collected in 2014 conducting a cross-sectional survey among managers (n=206) and employees (n=254) at a Dutch location of a large science-based multinational. Moderated regression analyses were used to test the hypotheses.

Findings
Career control was positively related to perceived employability. This relationship was significantly stronger for the managerial group that did participate in a career dialogue than for the managerial group that did not engage in a career dialogue. For the non-managerial group of employees participation in a career dialogue did not strengthen the relationship between career control and perceived employability.

Practical implications
Career control is beneficial for enhancing perceived employability among employees regardless of their position in the organization. Hence, training employees to master this competency may be a fruitful starting point for enhancing employability.

Originality/value
This is the first study to investigate whether the relation between career control, career dialogue and employability differs for employees with a managerial and a non-managerial role.
Mirror trade statistics between China and Latin America
Authors: Benita Francisco , Urzúa Carlos M. 
Published: November 2016

PurposeThis paper aims to examine the accuracy of the trade statistics between the People’s Republic of China and 20 Latin American countries: Argentina, Bolivia, Brazil, Chile, Colombia, Costa Rica, Cuba, Dominican Republic, Ecuador, El Salvador, Guatemala, Haiti, Honduras, Mexico, Nicaragua, Panama, Paraguay, Peru, Uruguay and Venezuela.Design/methodology/approachThis paper contrasts the mirror trade statistics between China and 20 Latin American countries during 2009-2014, after adding to the Chinese side the trade figures corresponding to Hong Kong and adjusting for some valuation issues. Using the resulting panel data, the paper then explores some of the possible explanatory variables, in the case of Latin America, which can account for the significant trade misinvoicing that is found among most of the countries involved.FindingsTrade misinvoicing, be that from the part of China or of its partners, varies substantially across Latin America. It is quite large in the case of some countries such as Bolivia, Costa Rica, Mexico, Panama and Paraguay, and, on the opposite side, relatively small in the case of other countries such as Argentina, Brazil, Chile, Guatemala and Venezuela. It is found that, from a Latin American perspective, trade misinvoicing is positively related to the countries’ lack of statistical capacity and their degree of financial openness.Originality/valueThis is the first empirical paper that examines the mirror trade statistics between China and Latin American.
Dependence between the Chinese and MILA stock markets
Authors: Mata Leovardo , Núñez Mora José Antonio 
Published: November 2016

Purpose
The purpose of this paper is to analyze the dependence between the Chinese and Market Integrated Latin America (MILA) stock markets.

Design/methodology/approach
The authors adjust the multivariate probability distribution Variance Gamma (VG) on data yields from the Hang Seng Index (HSI) and MILA and they use the estimated parameters under VG to find a robust estimator of the correlation matrix yields.

Findings
The degree of dependence between stock indices from China, Peru, Mexico, Colombia and Chile. In addition, the impact of the change in the HSI affects mostly the movements of the selective stock price index (IPSA) and equally affects the index of the Mexican stock exchange (IPC) and Lima Stock Exchange (S&P/BVL). The effect on index of the Colombia Stock Exchange (COLCAP) is not significant.

Research limitations/implications
Over time there are different structural changes so the time has been restricted to the years 2000-2015, but could extend the analysis to other time periods and sectors of listed companies in the indices.

Practical implications
The results can guide policy makers to assess the effect of a random crash on stock markets and measure the level of risk from other markets.

Social implications
The results can generate a greater understanding of the relationship between the stock markets of China and the emerging countries of Latin America.

Originality/value
The value of this paper is to focus on alternative methodology to calculate the correlation matrix yields and measure the dependence between the Chinese and MILA stock markets.
An enterprise based decision support system for engineering aggregate selection: a case study
Authors: Goswami Mohit , Singh Jaswinder , Kumar Vijay 
Published: November 2016

Purpose
The purpose of this paper is to develop a framework that would help manufacturers to select the design concept that provides optimal solutions to the entire value chain involving multiple functional teams such as product design, development, planning, sourcing, service and marketing. The selection of an optimal design concept is based on the highest value index of a design concept. This is derived from quality function deployment (QFD) and a functional analysis system using customer requirement, quality deployment, development and design constraint as inputs. The framework systematically considers different alternatives to converge at an optimal solution.

Design/methodology/approach
All high-level product requirements from customer and market analysis are translated into different engineering parameters using QFD. Thereafter, the functional analysis system technique (FAST) is employed to determine the range of functions and identify components that would achieve different functionalities. The relative importance of each function is determined by functional cost analyses, enabling us to generate different design concepts. Thereafter, business parameters are extracted from the business objective of each functional area. These business parameters are compared with different design concepts using the analytical hierarchical process (AHP), thus evolving the enterprise value index (EVI) for each design concept.

Findings
The design concepts are evaluated with different business parameters using the AHP methodology to form EVI. The design concept 2 with highest enterprise EVI (4.549) is selected for further development. To validate the consistency of the business parameters, the consistency ratio (CR) has been calculated using Saaty’s Eigenvector method. The value of CR is 8.4 per cent, which indicates that the judgment made in this paper as far as populating the business parameters weight matrix is concerned is quite reasonable. This framework would enable an enterprise’s dealing in the area of complex engineering systems/aggregates to choose the design concept that would maximize the value of the enterprise.

Originality/value
This research develops an integrated methodology for design concept selection from an enterprise point of view. Major functional agencies and their respective attributes are considered for the development of the framework and subsequent selection. An enterprise’s mission and vision framework function as the primary input for the extraction of related attributes of the functional agency.
A case study on application of ORESTE for agile concept selection
Authors: Arjun Raj A.S. , Vinodh Sekar 
Published: November 2016

Purpose
The purpose of this paper is to report a research on application of ORESTE (Organization, Rangement Et Synthese De Donnees Relationnelles, when translated into English means organization, storage and summarizing data relational) for agile concept selection.

Design/methodology/approach
The concept selection problem has been formulated as a multi-criteria decision-making (MCDM) problem to select the best concept design of the rotary switch component. ORESTE has been used as solution methodology. The selected concept design alternatives were subjected to implementation.

Findings
As ORESTE is a preferential outranking method, it uses ordinal data, enabling decision makers in situations where practically sufficient data are not available. This paper uses ORESTE for agile concept selection where gathering sufficient data is difficult. Also, the results generated by ORESTE have been compared with technique for order performance by similarity to an ideal solution.

Research limitations/implications
In the present study, ORESTE has been applied for concept selection of rotary switch component. In future, more number of studies need to be conducted to select more concept design alternatives where getting prior information is difficult or consumes more time to ensure practical effectiveness of ORESTE.

Practical implications
The application of ORESTE for concept design selection enabled the practitioners to select the best concept with ordinal data and also enabled scope for indifferentiability and incomparableness of any two alternatives in the final outranking.

Originality/value
Formulation of MCDM problem for agile concept selection and solution generation using ORESTE is the original contribution of the authors.
Data, Open Science and libraries – The Data Deluge Column
Authors: Frederick Donna Ellen 
Published: November 2016

Purpose
For those immersed in the environment of academic and research libraries, the word “data” seems to be everywhere. One hears about linked data, big data, open data, proprietary data, research data, metadata, geospatial data, data repositories, etc.

Design/methodology/approach
Some libraries even have data librarians and data services departments.

Findings
The author of this column wonders if she were to collect all of the library and information science literature published in the past three years and plug it into a word cloud app, which of the two, i.e. “data” or “books”, would be displayed in a larger font.

Originality/value
The author suspects that the chances are more than good that “data” would come out on top.
Peer-reviewed publications analysis of chemical engineering faculty at the University of Florida
Authors: Bharti Neelam , Bossart Jean 
Published: November 2016

Purpose
A citation analysis was conducted on publications of the faculty from the University of Florida (UF), Department of Chemical Engineering. The analysis was undertaken to gain a better understanding of the research programs in chemical engineering and to examine how the library aligns its research support through resources and journals to the needs of the department’s faculty. The analysis focused on where the faculty published, their most frequently cited resources, and what growth patterns were evident. The paper aims to discuss these issues.

Design/methodology/approach
Five years of publications (2011-2015) by the UF chemical engineering faculty were included in the analysis. Web of Science was used to compile a list of the articles published in peer-reviewed journals as well as the citations.

Findings
Faculty were found to have published 279 articles in the last five years, with 27 percent of those articles shared by five journals, and with an average impact factor of 3.459. Applied Physics Letters was the most cited journal and Advanced Materials had the highest impact factor of 17.493. The library owned 95 percent of the publications in which faculty published their work and at least 82 percent of the resources cited in their publications. The pattern of the publications was not consistent and the most articles in one year (69) were published in 2013.

Originality/value
Since this study focused on the current patterns regarding where the faculty are publishing and citing, it should be a fairly accurate indicator of their future needs. Therefore, the study impacts decisions regarding future directions by enabling the library to maintain a high-quality collection for the faculty.
Integrated sociotherapy – IS from rehabilitation to recovery integrating sociotherapy and cognitivism in a TC for borderline personality disorders
Authors: Lombardo Aldo 
Published: November 2016

Purpose
The purpose of this paper is to explain that an integration of cognitivism with sociotherapy is possible and appropriate to help severe BPD cases. What follows is both an outline and a rationale of this integration.

Design/methodology/approach
Recovery programs for serious BPD represent a challenge because they require complex answers in three problematic areas: interdependent relationships, emotional intensity and identity, virtually at the same time. This prompted Raymond Gledhill Community the opportunity to integrate recovery programs with treatments that have yielded proven results for each cluster. Schema therapy and Systems Training for Emotional Predictability and Problem Solving have been integrated with sociotherapy.

Findings
This integration has led to considerable results including: increased motivation among the resident community, the adoption of a shared language, improved communication levels in the community, greater mutual support, increased trust in, and empathy toward, fellow residents, and more self-awareness – even among the facilitators.

Originality/value
It is the belief that the integration of cognitive tools with sociotherapy can indeed target recovery for people with BPD in a much more efficacious and cost effective manner.
Group-apartments for recovery of people with psychosis in Italy: Democratic therapeutic communities in post-modern social communities
Authors: Bruschetta Simone , Barone Raffaele 
Published: November 2016

Purpose
The purpose of this paper is to present a model of democratic therapeutic community (DTC) for people with a diagnosis of schizophrenia and psychotic disorder, namely the Group-Apartment (GA). The authors will describe it in more detail, discussing the ideas which lie behind it, considering the relative cost of treating people in larger residential DTCs and in GAs, outlining findings from the first data gathered on a GA and looking at the usefulness of this model in post-modern societies, with particular reference to Sicily.

Design/methodology/approach
In brief a GA is a flat, located in an urban apartment building, inhabited by a small group of people. In this paper the authors consider an apartment inhabited by a group of three or four patients with the presence of clinical social workers who work in shifts for several hours a day on all or most days of the week (Barone et al., 2009, 2010). GA is also inspired by the pioneering work of Pullen (1999, 2003), in the UK tradition of the apartment post TC for psychosis.

Findings
GAs in Italy have become one of the main methods of support housing in recovery-oriented treatment, because it allows the empowerment of the users and fights against the stigma of mental illness (Barone et al., 2014; Bruschetta et al., 2014). The main therapeutic activities provided in the GA depend on the type of recovery route being supported, on the level of autonomy being developed and on the level of participation in the democratic life of the local community.

Originality/value
GAs appear better, cheaper and a more appropriate treatment for mental problems in the current financial and social climate than larger institutions. Where they have been tried out, they have been found to be effective, by users and by stakeholders. They exemplify the advantages of the DTC for encouraging recovery, but cost less to run. In accordance with DTC principles, the social democratic process is used not only to evaluate the clinical effectiveness of GAs, but also to build a network to support the development of innovative mental health services and new enabling environments (Haigh et al., 2012).
