Abstract

BACKGROUND
Bibliometrics is defined as the study of statistical and mathematical methods used to quantitatively analyze scientific literature. The application of bibliometrics in neurosurgery continues to evolve.

OBJECTIVE
To calculate a number of publication productivity measures for almost all neurosurgical residents and departments within North America. These measures were correlated with survey results on the educational environment within residency programs.

METHODS
During May to June 2017, data were collected from departmental websites and Scopus to compose a bibliometric database of neurosurgical residents and residency programs. Data related to authorship value and study content were collected on all articles published by residents. A survey of residency program research and educational environment was administered to program directors and coordinators; results were compared with resident academic productivity.

RESULTS
The median number of publications in residency was 3; median h-index and Resident index were 1 and 0.17 during residency, respectively. There was a statistically significant difference in academic productivity among male neurosurgical residents compared with females. The majority of articles published were tier 1 clinical articles. Residency program research support was significantly associated with increased resident productivity (P < .001). Scholarly activity requirements were not associated with increased resident academic productivity.

CONCLUSION
This study represents the most comprehensive bibliometric assessment of neurosurgical resident academic productivity during training to date. New benchmarks for individual and department academic productivity are provided. A supportive research environment for neurosurgical residents is associated with increased academic productivity, but a scholarly activity requirement was, surprisingly, not shown to have a positive effect.

Abstract
We present the structure of the Milky Way stellar halo beyond Galactocentric distances of r = 50 kpc traced by blue horizontal-branch (BHB) stars, which are extracted from the survey data in the Hyper Suprime-Cam Subaru Strategic Program (HSC-SSP). We select BHB candidates based on (g, r, i, z) photometry, where the z-band is on the Paschen series and the colors that involve the z-band are sensitive to surface gravity. About 450 BHB candidates are identified between r = 50 kpc and 300 kpc, most of which are beyond the reach of previous large surveys, including the Sloan Digital Sky Survey. We find that the global structure of the stellar halo in this range has substructures, which are especially remarkable in the GAMA15H and XMM-LSS fields in the HSC-SSP. We find that the stellar halo can be fitted to a single power-law density profile with an index of α ≃ 3.3 (3.5) with (without) these fields and its global axial ratio is q ≃ 2.2 (1.3). Thus, the stellar halo may be significantly disturbed and be made in a prolate form by halo substructures, perhaps associated with the Sagittarius stream in its extension beyond r ∼ 100 kpc. For a broken power-law model allowing different power-law indices inside/outside a break radius, we obtain a steep power-law slope of α ≃ 5 outside a break radius of ∼100 kpc (200 kpc) for the case with (without) GAMA15H and XMM-LSS. This radius of 200 kpc might be as close as a halo boundary if there is any, although a larger BHB sample is required from further HSC-SSP surveys to increase its statistical significance.
Current Approach to the Diagnosis and Management of Shoulder Dislocation in Children
Authors: Gottlieb Michael 
Published: May 2018

Abstract
Shoulder dislocations are a common presentation to the emergency department. Although many cases may be diagnosed by history and clinical examination alone, imaging may help diagnose more challenging cases. Three-view radiographs are important for identifying subtle posterior dislocations, and ultrasonography has been gaining evidence as an alternate diagnostic modality. Intra-articular lidocaine and nerve blocks may improve pain control and reduce the need for procedural sedation. Multiple, evidence-based reduction techniques are described including tips for improving success. Immobilization strategies and follow-up are also discussed.

Published: May 2018

SUMMARYSoon after fertilization, the few totipotent cells of mammalian embryos diverge to form a structure called the blastocyst (BC). Although numerous types of cells, including germ cells and extended pluripotency stem cells, have been generated from pluripotent stem cells (PSCs)in-vitro, generating functional BCs only from PSCs has not yet been reported. Here we describe induced self-organizing 3D BC-like structures (iBCs) generated from mouse PSC culturein-vitro. Resembling natural BCs, iBCs have a blastocoel-like cavity and were formed with outer cells that are positive for trophectoderm lineage markers and with inner cells that are positive for pluripotency markers. iBCs transplanted to pseudopregnant mice uteruses implanted, induced decidualization, and exhibited growth and development before resorption, demonstrating that iBCs are implantation-competent. iBC production required the transcription factor Prdm14 and iBC precursor intermediates concomitantly activate the MERVL totipotency related cleavage stage reporter. Thus, our system may contribute to understanding molecular mechanisms underpinning totipotency, embryogenesis, and implantation.HIGHLIGHTS-Pluripotent cells self-organize blastocyst-like structures in defined conditions.-Structures have several extraembryonic and embryonic characteristics of blastocysts.-Structures can implant in the uterus and grow before resorption.-Totipotency is implicated concomitantly at loci that originate induced blastocysts.

ABSTRACTAcetylcholine (ACh) regulates a diverse array of physiological processes throughout the body, yet cholinergic transmission in the majority of tissues/organs remains poorly understood due primarily to the limitations of available ACh-monitoring techniques. We developed a family ofG-protein-coupled receptor activation-basedAChsensors (GACh) with sensitivity, specificity, signal-to-noise ratio, kinetics and photostability suitable for monitoring ACh signalsin vitroandin vivo. GACh sensors were validated with transfection, viral and/or transgenic expression in a dozen types of neuronal and non-neuronal cells prepared from several animal species. In all preparations, GACh sensors selectively responded to exogenous and/or endogenous ACh with robust fluorescence signals that were captured by epifluorescent, confocal and/or two-photon microscopy. Moreover, analysis of endogenous ACh release revealed firing pattern-dependent release and restricted volume transmission, resolving two long-standing questions about central cholinergic transmission. Thus, GACh sensors provide a user-friendly, broadly applicable toolbox for monitoring cholinergic transmission underlying diverse biological processes.

ABSTRACTCyanobacteria are natural enormous sources of various biologically active compounds with great contributions in different industries. This study aimed to introduce molecular and biochemical characterization for four novel cyanobacterial isolates obtained from Egyptian wastewater canals. Besides, In vitro biological activity of these isolates and their potential ability to take up nutrients and heavy metals from wastewater were examined. The obtained accession numbers were KY250420.1, KY321359.1, KY296359.1 and KU373076.1 for Nostoc calcicola, Leptolyngbya sp, Nostoc sp, and Nostoc sp, respectively. The isolate Leptolyngbya sp (KY321359.1) showed the lowest identity (90%) with other deposited sequences in database. While the isolate Nostoc sp (KU373076.1) showed the highest total phenolic content as well as the highest levels of caffeic, ferulic and gallic acids. Consequently, it appeared the highest antioxidant scavenging activity. All cyanobacterial isolates revealed potent ability to take up nutrients and heavy metals from wastewater. Generally, this study provides a taxonomic and molecular evidence for four novel cyanobacterial isolates with antioxidant activity and potent phycoremediation ability.
Sex Determination in the garden lizard, Calotes versicolor: Is Environment a Factor?
Authors:   Priyanka, Raman Rajiva 
Published: May 2018

AbstractThe Indian garden lizard, C. versicolor, is known to lack sex chromosomes (Singh, 1974, Ganesh et al 1997). A report from the tropical southern India (Inamdar et al., 2012), claims a TSD (FMFM) mechanism in this species in which the male/female ratio in embryos oscillates within a range of 3-4°C. The present study presents results of experiments done in 4 consecutive breeding seasons of C. versicolor belonging to the subtropical/temperate climate of northern region of India. Eggs were grown at different temperatures (at 24.5/28/31.5°C) or under seminatural conditions. Another set of eggs was exposed to fadrozol, an aromatase inhibitor (AI), or Lithium Chloride (inhibitor of GSK3 enzyme inducing Wnt4-dependent Beta-Catenin). Results confirm our earlier finding that in this subtropical population of C. versicolor, temperature does not regulate gonadal differentiation but AI-induces sex reversal to the male sex (Ganesh and Raman, 1995, Ganesh et al 1999). We also report lack of any effect of Sox9 inhibitor on sexual differentiation which may be due to inadequate quantity or mode of application. Importantly, we report the serendipitous observation that in each year almost all the embryos/hatchlings were of the same sex ( females in 2013, ’15, ’16 and males in 2014) regardless of the rearing condition and duration of incubation. Obviously, parthenogenesis is not the cause of it. In the absence of an obvious reason to explain this pattern, we surmise that in this north Indian population of C. versicolor, female is the default sex, and certain epigenetic regulators could modulate the sexual differentiation of the individual.

AbstractDeep sequencing based genetic mapping has greatly enhanced the ability to catalog variants with plausible disease association. The bigger challenge now is to ascertain pathological significance to the array of identified variants to specific disease conditions. Differential selection pressure may impact frequency of genetic variations, and thus the detection of association with disease conditions, across populations. To understand the genotype to phenotype correlations, it thus becomes important to first understand the genetic variation spectrum of a population by creating a reference map. In this study, we report the development of phase I of a new database of coding variations, from the Indian population, with an aim to establish a centralized database of integrated information. This could be useful for researchers involved in studying disease mechanism at the clinical, genetic and cellular level.Database URL: http://indexdb.ncbs.res.in
Capitalism goes care
Authors: Aulenbacher Brigitte , Décieux Fabienne , Riegraf Birgit 
Published: May 2018

PurposeThe starting point of the paper is the meteoric rise of care and care work upon the societal and sociological agenda. Referring to Polanyi, the authors argue that this is the manifestation of a new phase of capitalist societalisation (Vergesellschaftung) of social reproduction in the form of an economic shift. The purpose of this paper is to discuss the societal organisation of care and care work and questions of inequality and justice.Design/methodology/approachThe first part of the paper illustrates some facets of the economic shift in the field of care and care work. The second part reconstructs the societal organisation of care and care work in the private sector, state, third sector and private households from the mid-twentieth century in the context of questions of inequality and justice. The third part draws on the institutional logics perspective and French pragmatic sociology and the own case studies on home care agencies (HCA), residential care communities (RCC) and early child care (ECC) in Austria and Germany and shows how conflicting demands give rise to new questions of justice. The paper ends with a short conclusion.FindingsThe paper shows how the commodification and de-commodification of care and care work have changed over time and how the economic shift – illustrated in the case of HCA, RCC and ECC – is accompanied by conflicting demands and questions of justice.Originality/valueA Polanyian perspective on the relation between market and society is combined with the neo-institutionalist and pragmatic idea that orientations rooted in the “logics” of the market, the state, the family and the profession influence how conflicting demands in elder and child care are dealt with and how questions of inequality and justice arise.

PurposeStrategic planning is the best tool for managers seeking an informed presence and participation in the market without surrendering to changes. Strategic planning enables managers to achieve their organizational goals and objectives. Hospital goals, such as improving service quality and increasing patient satisfaction cannot be achieved if agreed strategies are not implemented. The purpose of this paper is to investigate the factors affecting strategic plan implementation in one teaching hospital using interpretive structural modeling (ISM).Design/methodology/approachThe authors used a descriptive study involving experts and senior managers; 16 were selected as the study sample using a purposive sampling method. Data were collected using a questionnaire designed and prepared based on previous studies. Data were analyzed using ISM.FindingsFive main factors affected strategic plan implementation. Although all five variables and factors are top level, “senior manager awareness and participation in the strategic planning process” and “creating and maintaining team participation in the strategic planning process” had maximum drive power. “Organizational structure effects on the strategic planning process” and “Organizational culture effects on the strategic planning process” had maximum dependence power.Practical implicationsIdentifying factors affecting strategic plan implementation is a basis for healthcare quality improvement by analyzing the relationship among factors and overcoming the barriers.Originality/valueThe authors used ISM to analyze the relationship between factors affecting strategic plan implementation.

Published: May 2018

Purpose
Constipation in hospitalised older adults leads to adverse events and prolonged stay. The purpose of this paper, therefore, is to effectively prevent and manage constipation in older adults undergoing inpatient rehabilitation using a multidisciplinary war on constipation (WOC) algorithm.

Design/methodology/approach
A quality improvement project in older adults undergoing rehabilitation for prevention and constipation management was conducted. Quality improvement “plan-do-study-act” cycles included an initial constipation audit in the wards and meetings with the multidisciplinary team (MDT) to develop an algorithm for the preventing, detecting and effectively treating constipation.

Findings
The project resulted in a 14 per cent reduction in constipation incidence after the newly developed WOC algorithm was introduced. The project also improved communication between patients and the MDT around patients’ bowel habits.

Practical implications
The project shows that using quality improvement methods in rehabilitation settings, earlier detection, earlier intervention and overall reduction in constipation in older adults can be achieved.

Originality/value
The WOC algorithm has been developed and institutionalised in the current setting. This algorithm may also be applicable in other inpatient settings.
Participatory place-making in the renewal of post-Communist large prefabricated housing estate
Authors: Benkő Melinda , Balla Regina , Hory Gergely 
Published: May 2018

Purpose
The purpose of this paper is to introduce a Central-European perspective into the international discussion of the participatory place-making. The research focuses on the renewal of the large prefabricated housing estates, dominant type of urban housing in the area where after the privatisation process resident-owners own only a so-called floating plot under their block. In total, 80 per cent of the land of the whole neighbourhood remains public. The question is how participatory place-making works in this specific urban, social and cultural situation?

Design/methodology/approach
By introducing the topic from a theoretical point of view, the study is based on research conducted in Budapest’s Újpalota Housing Estate. Fieldwork, project analysis and interviews uncover the complexity of this Hungarian case where appropriation of residents, municipality and European social regeneration projects are simultaneously present with different types of participatory methods.

Findings
The majority of real changes in Újpalota – as well as in housing estates of post-Communist countries in general – are led by individual or common appropriation that sometimes becomes convincing participation. This informal transformation of the built or natural environment can create a small sense of place everywhere. At the same time, it can work against the architectural and urban character of a neighbourhood or a building, rendering a feeling of disorder.

Originality/value
The paper based on this Hungarian case shows that the real culture of participatory place-making is still missing in post-Communist context, and despite some good examples, the majority of people are inactive, waiting for changes to be made by leaders.
Exploring theoretical trends in placemaking: towards new perspectives in spatial planning
Authors: Strydom Wessel , Puren Karen , Drewes Ernst 
Published: May 2018

PurposeWhile placemaking is a multi-disciplinary concern, it is a key focus within the discipline of spatial planning. This paper aims to explore the development of theoretical trends with regard to placemaking in spatial planning since 1975 to identify current emerging theoretical perspectives. Special attention is given to differences in perspectives between the Global North and the Global South.Design/methodology/approachThe study used an integrative literature review (ILR) to analyse placemaking literature over a period of 41 years and five months. The ILR followed the basic review stages: scoping; planning and review protocol; identification/availability; searching; and screening. ILR differs from other reviews as quality appraisal, data gathering, analysis and synthesis rely on coding, thematic content analysis and synthesis.FindingsInitially, the planning/review protocol resulted in 59 contributions on placemaking in various disciplines (excluding publications in other languages that English). Contributions included spatial and design disciplines (29 contributions), social sciences (14 contributions) and other disciplines (16 contributions). The literature review proceeded with a selection of 23 spatial planning contributions (20 from the Global North and three from the Global South). Theoretical trends include placemaking theorised as a physical construct, a social construct, an economic construct (absent in literature from the Global South), a tool for empowerment, a psychological dimension and an environmental management tool.Practical implicationsThe most recent theoretical perspectives in literature suggest placemaking as an enabling tool in which people share knowledge and learn new skills to transform their own environment. This empowering process creates a linkage between planning theory and practice.Originality/valueThis paper contributes to the current theories of placemaking in spatial planning. It provides a simplified view of an exhaustive list of existing literature. This paper reports on the current trends and the development of placemaking theory.
The impact of internal audit function characteristics on internal control quality

Published: May 2018

PurposeThis paper aims to investigate the association between internal audit function (IAF) characteristics and internal control quality.Design/methodology/approachUsing data gathered from 59 chief audit executives from Tunisian listed companies, this paper uses a regression model to examine research hypothesis related to the association between IAF characteristics and internal control quality.FindingsThe findings of the current study reveal that internal control quality is significantly and positively associated with IAF competence, internal audit quality control assurance level, follow-up process and audit committee’s involvement in reviewing the internal audit program and results.Practical implicationsThe findings have significant implications for IAF wishing to enhance their effectiveness, by recognizing the impact of the IAF’s characteristics on internal control quality. The findings of this study also have significant implications for regulatory bodies who are concerned with the internal control quality, managers and audit committees who determine IAF investment, oversight IAF activities and assess internal auditors’ performance.Originality/valueThis study helps fill a gap in the extant literature where existing empirical evidence of how the IAF characteristics influences the quality of the financial reporting process in emerging markets is scant.
