The Promises and Pitfalls of Engaging Male Juvenile Offenders in Gender Violence Prevention and Bystander Education
Authors: Opsal Tara , Aguilar Jade , Briggs Steven
Published: October 2016

Drawing on interviews with and observations of boys enrolled in a bystander violence prevention program at a juvenile detention center, this article provides a sociological case study on how the boys’ biographies and violent lived experiences shaped their engagement with the program. Previous research on bystander prevention programs has typically focused on men enrolled in college who do not have the same kinds of violent histories as the boys in this study do. This article builds upon prior research on prevention programs by demonstrating how at-risk youth participants understand and access the program. We offer suggestions for tailoring bystander prevention programs to more adequately address the specific needs of these populations.

Authors: Garrido Castellano Carlos
Published: October 2016

This essay analyzes A Cultural Object, an installation made by the Jamaican artist Dawn Scott in 1985, in order to discuss how institutional practices and criticism are framed in contemporary Caribbean art. Through an examination of A Cultural Object’s afterlife in the space of the National Gallery of Jamaica, I attempt to examine the relation between the agencies of the museum, the artist, the spectators, and the installation. In so doing, the text intends to reconsider the potential of unpredictable human and nonhuman relations within Caribbean institutional and cultural spaces.
Numerical and experimental investigations on flow regulation of fuel vapor core pump
Authors: Wang Bin , Guan Huasheng , Ye Zhifeng
Published: October 2016

Vapor core pump, unlike traditional centrifugal pumps with bypass throttling, exhibits the superiority in active fuel regulation. The vapor–liquid two-phase flow inside vapor core pump is an interesting process over its full regulation range, which influences performance of the pump. In this paper, an enclosed radial straight blade vapor core pump is selected as the object. Through vapor–liquid two-phase numerical simulation, the configuration of the vapor core in impeller zone and the regulation performance of the pump are obtained under several typical operating conditions. The main innovation in the simulation is that vapor volume fraction inside the pump as a means of actual vapor core description is obtained through numerical method with the Schnerr–Sauer cavitation model based. Vapor-phase volume fraction, velocity, head, and efficiency in relation to the opening or fuel rate are calculated and analyzed with inlet or outlet load changing. Performance testing on a vapor core pump prototype is carried out to verify the numerical results. Comparison between the experiment and the simulation shows the acceptable difference between them and the effectiveness of the numerical method. Study results indicate that a vapor core pump has a wide active regulation range of fuel delivery rate. For pure vapor core conditions, a considerable efficiency loss is unavoidable. Inlet throttling and hydraulic loss in its impeller play a significant role in deviated flow regulation characteristics. The opening size and the inlet or outlet load affect the pump delivery performance, which could be used to choose proper operation conditions or regulation range where neither much efficiency loss nor other performance degeneration on the pump occurs.
Learning Organisation Activities and Innovativeness of Tech-based SMEs within Korean Technoparks: The Mediating Role of Learning Transfer
Authors: Sung Sanghyun , Rhee Jaehoon , Yoon Junghyun
Published: October 2016

Developing talented human resources through learning entails nurturing innovation and improving competitiveness; to achieve innovation, tech-based SMEs within or around Korean technoparks must undertake learning organisation activities (LOAs). Our results demonstrate that six dimensions of the LOA model have more validity or a better model fit than the previous seven dimensions of the LOA model. Furthermore, three important sub-variables of LOAs (i.e., creating continuous learning opportunities, establishing systems to capture and share learning and providing strategic leadership for learning) have a positive and significant effect on learning transfer. Finally, transferring LOAs was found to mediate the relationship between LOAs and innovativeness by creating continuous learning opportunities (and future directions) and by providing strategic leadership for learning.
Does Inward Foreign Direct Investment Lead Export Performance in Pakistan?
Authors: Jawaid Syed Tehseen , Raza Syed Ali , Mustafa Khalid , Karim Mohd Zaini Abd
Published: October 2016

This study is a pioneering attempt to investigate the impact of foreign direct investment (FDI) on export performance in Pakistan by using the long annual time series data from the period 1974–2012 and by using more rigorous econometric techniques. Autoregressive distributed lag-bound testing cointegration approach confirms the valid long-run relationship between considered variables. Results indicate the significant positive impact of FDI on real exports in long run as well as in short run. Results of Granger causality test, Toda and Yamamoto Modified Wald causality test and variance decomposition test confirm the bidirectional causal relationship between FDI and export performance in Pakistan. Results of rolling window analysis suggest that the coefficient of FDI in export model remains negative from 1983 to 1987, from 2001 to 2006 and in 2011. The coefficient of FDI in export model shows a positive coefficient in remaining years. It can be seen that FDI and real export are connected in complementary way in Pakistan. The policy makers should make policies that favour foreign investors so as to attract more FDI in Pakistan. It has been observed that a stable political and economic environment is desirable to attract more FDI in Pakistan.
Asymmetric Dynamic Conditional Correlation Approach to Financial Contagion: A Study of Asian Markets
Authors: Rajwani Shegorika , Kumar Dilip
Published: October 2016

The study seeks to examine the contagion effect of the global financial crisis on the major Asian markets, namely, China, Hong Kong, Indonesia, South Korea, Malaysia, Japan, India and Taiwan. The study incorporates the impact of leverage effect in the dynamic conditional correlation generalized autoregressive conditional heteroskedasticity (DCC-GARCH) framework to achieve the goal. The US is taken as the crisis-originating country. The period of study has been divided into three categories, namely, pre-crisis period, crisis period and post-crisis period, to examine the sudden change in average conditional correlation from one period to other period so as to identify the contagion effect. The findings support the contagion effect from US market to the major Asian markets with the exception of Japan. Policy makers seek to study the existence of contagion among markets so that they can strategically manage risk and it further helps in asset allocation. If the markets are contagious, then the investors will be unable to reap benefits through international diversification of portfolio. In such a case, the policy makers will further frame policies so that they can insulate themselves from inflicting heavy damage from various crises.
The Effects of Capital Formation on Economic Growth in India: Evidence from ARDL-bound Testing Approach
Authors: Bal Debi Prasad , Dash Devi Prasad , Subhasish Bibhudutta
Published: October 2016

This article examines the impact of capital formation on economic growth in India covering the period from 1970 to 2012. This paper traces a long-run equilibrium relation between capital formation and economic growth and other control variables by using autoregressive distributed lag (ARDL) model. The error correction (ECM) model shows that the capital formation, trade openness, exchange rate and total factor productivity positively affect the economic growth and the inflation negatively affects the economic growth in the short run. It is recommended that government increases the level of capital formation in order to achieve a higher level of economic growth.
Cooperatives as Alternative Form of Organization for CSR Effectiveness: Insights from Rabindranath Tagore
Authors: Mukherjee Sanjoy , Pyne Summauli
Published: October 2016

Increasing thrust on sustainability has pervaded every form of organization today including business. Active involvement and participation in community activities is no more considered an act of traditional philanthropy but an integral and significant part of the business model and operations for inclusive growth of the multiple stakeholder constituencies along with the organization. This also throws challenges to modern organizations to look for alternative forms and redefined priorities beyond the confines of single-pointed pursuit of profits and economic growth. The present article primarily engages in this search for ‘the other’ form of organization in the pioneering initiative for rural regeneration by the Nobel Laureate poet and philosopher from India Rabindranath Tagore at Sriniketan, in the district of Birbhum in West Bengal. Sriniketan was a novel venture to uplift the neglected village and bridge the gap between the urban and the rural milieu. In this regard, this article will undertake a detailed study of Tagore’s twin objectives—first, to educate the villagers in self-dependence and second, to gift the villagers a complete life. It will also attempt to uphold the ideal of village welfare as envisioned by Tagore through people-centric education with the help of local and global experts. The article explores through a qualitative study of Tagore’s Sriniketan, a rural development project directed towards sustainability in viewing the spirit of cooperatives as an alternative form of organization. It will also finally highlight on how modern organizations can draw lessons on sustainability from Tagore’s cooperative movement for creative and effective corporate social responsibility (CSR) interventions.
Evaluation of a motivational pre-exercise music intervention
Authors: Hallett Rachel , Lamont Alexandra
Published: October 2016

While music has been found to motivate exercisers during workouts, its potential as a pre-exercise motivator has rarely been investigated. This study evaluated a self-selected, pre-exercise music intervention against implementation intentions (writing down ‘if … then …’ sentences relating to overcoming barriers) and a control condition. A total of 50 participants ( Mage = 43) took part in a longitudinal, randomised, between-participants study, from 99 recruited. For both interventions, participants had significantly more success meeting self-set exercise goals than the control group, and the music group exercised significantly more frequently than the control group. There was support for music as a comparable intervention to implementation intentions.
Impact of the Europeanisation of education: Qualifications frameworks in Europe
Authors: Mikulec Borut
Published: October 2016

This article examines the influence of the European qualifications framework – a key European lifelong learning policy instrument for improving employability, comparability and mobility in the European educational space – on the establishment of national qualifications frameworks in Europe. The European qualifications framework and national qualifications frameworks are analysed through the lens of the process of the Europeanisation of education, and they are embedded in the broader context of the development of national qualifications frameworks in Anglo-Saxon and developing countries around the world. Against this background and through an analysis of established national qualifications frameworks in four European countries, i.e. Denmark, Germany, Portugal and Slovenia, we argue that the national qualifications frameworks in these countries cannot be understood to be tools for the deregulation, marketisation and commodification of education and knowledge, although this could be interpreted as one of the underlying hidden assumptions of the European qualifications framework recommendation.
A neural response-based model to predict discomfort glare from luminance image
Authors: Safdar M , Luo M Ronnier , Mughal M Farhan , Kuai S , Yang Y , Fu L , Zhu X
Published: October 2016

It is well known that one of the problems of the current method for discomfort glare evaluation, called the unified glare rating, is the non-uniform luminance of the glare source. This paper addresses this issue by considering the spatial contrast of luminance as a measure of non-uniformity. An image-based metric is proposed to evaluate discomfort glare by modeling the neural response of human vision. The model takes an absolute luminance image as input and predicts visual discomfort based on the spatial distribution of the luminance of the stimulus and the background. The developed model was tested to predict subjective glare ratings based on an experiment conducted using non-uniform LED sources with symmetric and asymmetric patterns of LEDs, and its performance was compared with the unified glare rating. As expected, the unified glare rating predictions correlated well with the subjective glare evaluations of luminaires with symmetric patterns of LEDs (as they appear less non-uniform) but not for those with asymmetric patterns. Results showed that the developed model, named the Neural Response-based Glare Model, gave similar performance to unified glare rating for symmetric patterns but outperformed UGR for asymmetric patterns of LEDs.
Coaxial nanofibers from poly(caprolactone)/ poly(vinyl alcohol)/Thyme and their antibacterial properties
Authors: Koushki Pantea , Bahrami S Hajir , Ranjbar-Mohammadi Marziyeh
Published: October 2016

Today, with substantial global demand from patients suffering from wounds and burns, the wound care sector has gained great deal of interest in medical industry. Herein, coaxial electrospun poly(caprolactone)/poly(vinyl alcohol) core–shell nanofibers incorporated with Thyme extract in the core structure were prepared using coaxial electrospinning, and the effect of various operational parameters such as polymer concentration, applied voltage, flow rate, distance, and Thyme concentration on nanofiber diameter were studied. Physical and mechanical properties of the nanofibers were determined by analytical techniques. The results revealed that desired nanofibers with uniform surface morphology and acceptable tensile strength could be obtained at applied voltage of 15 kV, needle tip-target of 13 cm, core flow rate of 0.2 mL/h, and shell flow rate of l mL/h. Moreover, MTT assay shows that the nanofibers are highly biocompatible regardless of Thyme encapsulation. Antibacterial activities of the prepared core–shell nanofibers were also examined against two bacteria—gram-positive Staphylococcus and gram-negative Escherichia. Encapsulation of 5% (w/v) Thyme extract concentration in the core–shell poly(caprolactone)/poly(vinyl alcohol) nanofibers led to high antibacterial activity of the produced nanofibers.
Research on the propagation path of function change in product conceptual design
Authors: Jiang Shaofei , Li Jiquan , Mao Zhifei
Published: October 2016

Product design was a repetitive process. Given that product structure was closely related to functions, function change was vital to the final design and core of design change. The effect of predicting function change during conceptual design on the final product structure was important to improve the design quality. A model was proposed to predict the propagation path of function change during conceptual design. Based on function–behavior relationship and behavior–structure relationship, a function–behavior–structure model of product design history was established. The propagation scope of function change in the functional layer was determined by analyzing input/output streams of functions. Function change was mapped onto behavior structure. The propagation scope of behavior change in the behavior layer was determined by analyzing the input/output state consistency of behavior. The changed parts were identified through behavior–structure relationship. Finally, the propagation path of function change was represented completely. The proposed propagation model of function change can provide a reference for quick product design. The feasibility and validity of the proposed model were verified through a case study, particularly the function change of monocular ice crusher.
Railway rolling bearing fault diagnosis based on multi-scale intrinsic mode function permutation entropy and extreme learning machine classifier
Authors: Yao Dechen , Yang Jianwei , Bai Yongliang , Cheng Xiaoqing
Published: October 2016

The application of the multi-scale intrinsic mode function permutation entropy and extreme learning machine classifiers in railway rolling bearing fault diagnosis is here proposed in this article. The original signal is first denoised using wavelet de-noising as a pre-filter, which improves the subsequent decomposition into a number of intrinsic mode functions using ensemble empirical mode decompose. Second, the multi-scale intrinsic mode function permutation entropy is extracted as feature parameters. Finally, the extracted features are entered into extreme learning machine for an automated fault diagnosis procedure. Case studies have been carried out to evaluate the validity of the approach. The results demonstrate its effectiveness for diagnosis of faults in railway rolling bearings.
Torque ripple reduction of induction motor based on a hybrid method of model predictive torque control and particle swarm optimization
Authors: Su Te-Jen , Tsou Tung-Yeh , Wang Shih-Ming , Li Tsung-Ying , Vu Hong-Quan
Published: October 2016

The quality of torque of induction motors plays an important role in many electrical drive systems. Model predictive torque control has been a good alternative to conventional direct torque control for improving the torque qualities. Recently, some researchers tried to modify the model predictive torque control with other principles such as minimize torque ripple, optimize duty cycle, in an effort to get smaller torque ripples. However, according to the reported results the torque ripples are still significant. In this article, model predictive torque control based on particle swarm optimization is proposed to modify the model predictive torque control in order to improve the control qualities, especially the steady-state torque ripples. The key idea of this approach is using particle swarm optimization to minimize the cost function. The optimal voltage vector is implemented by space vector modulation technique. In addition, the control performance of model predictive torque control–particle swarm optimization combination is also compared with that of model predictive torque control–genetic algorithm to justify the effectiveness of our method. The presented simulations prove the better torque and phase currents quality at steady state of this approach.
Strength of evidence for labeled dosing recommendations in renal impairment
Authors: Gagne Joshua J , Khan Nazleen F , Raj Tara S , Patel Lajja R , Choudhry Niteesh K
Published: October 2016

Background/Aims:

Renally excreted medications often require dose adjustment in patients with kidney impairment. While drug development and approval in the United States are typically based on several Phase I and II studies and one or more larger Phase III randomized trials, the basis for labeled dosing recommendations for patients with renal impairment is less well known. In response, we aimed to quantify the level of evidence used to recommend labeled dosing adjustments for newly approved drugs in patients with renal impairment.

Methods:

We reviewed publicly available drug labels and approval packages for new molecular entities approved in the United States between 2012 and 2014. The sample was restricted to 29 renally excreted new molecular entities that were not granted orphan drug status. We extracted data regarding approved indications, normal dosing, dosing adjustments for patients with mild (estimated glomerular filtration rate >60 mL/min/1.73 m2), moderate (estimated glomerular filtration rate 30–<60 mL/min/1.73 m2), and severe (estimated glomerular filtration rate <30 mL/min/1.73 m2) renal impairment, characteristics of studies used to justify dosing adjustments, and numbers of subjects in each study.

Results:

In all, 14 of 29 (48%) new molecular entities had labels that recommended dosing adjustments for patients with mild, moderate, and/or severe renal impairment. Among these 14 new molecular entities, 4 (29%) used only pharmacokinetic studies to justify the recommendations, with no examination of clinical outcomes for patients with renal impairment. Where data were available, the median number of patients with renal impairment evaluated in studies used for dosing adjustment was 34 (range, 4–5976). Of the 15 new molecular entities with no recommended dosing adjustments for this population, 2 (13%) did not report assessing the effects of renal impairment.

Conclusion:

Nearly half of newly approved renally excreted drugs include dosing adjustments for kidney impairment on the label, but the recommendations are usually based on very small numbers of patients and often utilize pharmacokinetic studies alone. More research is needed to understand the benefits and risks of new drugs in patients with renal impairment.
Blocking mammalian target of rapamycin alleviates bladder hyperactivity and pain in rats with cystitis
Authors: Liang Simin , Li Jie , Gou Xin , Chen Daihui
Published: October 2016

Background

Bladder disorders associated with interstitial cystitis are frequently characterized by increased contractility and pain. The purposes of this study were to examine (1) the effects of blocking mammalian target of rapamycin (mTOR) on the exaggerated bladder activity and pain evoked by cystitis and (2) the underlying mechanisms responsible for the role of mTOR in regulating cystic sensory activity.

Results

The expression of p-mTOR, mTOR-mediated phosphorylation of p70 ribosomal S6 protein kinase 1 (p-S6K1), 4 E–binding protein 4 (p-4 E-BP1), as well as phosphatidylinositide 3-kinase (p-PI3K) pathway were amplified in cyclophosphamide rats as compared with control rats. Blocking mTOR by intrathecal infusion of rapamycin attenuated bladder hyperactivity and pain. In addition, blocking PI3K signal pathway attenuated activities of mTOR, which was accompanied with decreasing bladder hyperactivity and pain. Inhibition of either mTOR or PI3K blunted the enhanced spinal substance P and calcitonin gene-related peptide in cyclophosphamide rats.

Conclusions

The data for the first time revealed specific signaling pathways leading to cyclophosphamide-induced bladder hyperactivity and pain, including the activation of mTOR and PI3K. Inhibition of these pathways alleviates cystic pain. Targeting one or more of these signaling molecules may present new opportunities for treatment and management of overactive bladder and pain often observed in cystitis.

Variables Affecting Return to Play After Anterior Cruciate Ligament Injury in the National Football League
Authors: Eisenstein Emmanuel D. , Rawicki Nathaniel L. , Rensing Nicholas J. , Kusnezov Nicholas A. , Lanzi Joseph T.
Published: October 2016

Background:

Anterior cruciate ligament (ACL) injuries are common in the National Football League (NFL). Limited literature exists regarding return to play (RTP) and the factors affecting RTP after ACL reconstruction in NFL players.

Purpose/Hypothesis:

To determine RTP rates after ACL reconstruction in NFL players and to ascertain which variables affect RTP in these players. We hypothesized that RTP in this population will be less than in the general population and similar to the limited studies published previously.

Study Design:

Case-control study; Level of evidence, 3.

Methods:

A total of 92 NFL athletes who sustained ACL injuries requiring ACL reconstruction from 2013 to 2015 were retrospectively studied to determine rate of RTP and the variables affecting RTP.

Results:

Sixty-two percent (57/92) of NFL athletes returned to NFL game play prior to the end of the 2015-2016 postseason. ACL injuries were noted in 10 different player positions, with 81.5% of all injuries as isolated ACL injuries (75/92) and 18.5% with concomitant knee injuries. A significant difference in ability to RTP was found for players who sustained in-season injuries compared with those who sustained off-season/preseason injuries ( P = .02). No significant differences in RTP were found for players who played less than 4 years in the NFL compared with those who played longer. The mean draft round of players who returned was 3.96, with the odds ratio favoring RTP at 4.44 ( P = .003) for players drafted in the first 3 rounds of the NFL draft compared with those drafted in the fourth round or later. No significant differences were found with regard to playing surface, laterality, concomitant injury, previous ipsilateral or contralateral ACL reconstruction, final outcome of the game, or contact compared with noncontact injuries.

Conclusion:

The RTP rates we reported after ACL reconstruction in NFL players are similar to prior studies; however, running backs and wide receivers had lower rates of RTP than previously reported. As previously published, quarterbacks were found to have high RTP rates. Most ACL injuries take place during the preseason or early regular season. Early selection in the NFL draft was a strong predictor of ability to RTP.
Facilitating and Managing Joint Creativity at the Manufacturer–Retailer Interface
Authors: Strutton David , Guzmán Francisco
Published: October 2016

Within the supply chain literature, little attention has been given to the development of creativity at the manufacturer–retailer (M–R) interface. This conceptual study closes this knowledge gap by justifying, developing and discussing a ‘Collaborative Supply Chain Creativity–Learning’ Matrix. If used, the matrix would promote more effective facilitation and management of joint ideational creativity at the M–R interface. The matrix itself is based, and justified, on the premise that managing ideation processes more effectively is a necessary precursor to any supply chain or supply chain’s partnership’s ability to create superior value. The matrix features 10 methods designed to facilitate both ‘divergent’ and ‘convergent’ creative activities. The ability to facilitate divergent thinking should promote the development of greater numbers of highly creative M–R ideas. The ability to engage successfully in convergent thinking should further ensure that only the most useful new ideas are developed. At net, greater creativity will result at any point within any supply chain setting where the human representatives ‘intersect and interact’ for purposes of addressing pressing problems or jointly pursuing attractive opportunities and creating value.
Using the Affiliate Stigma Scale with caregivers of people with dementia: psychometric evaluation
Authors: Chang Chih-Cheng , Su Jian-An , Lin Chung-Ying
Published: October 2016

Background

In this study, we examined the psychometric properties of the Affiliate Stigma Scale to measure affiliate stigma for caregivers of family members with dementia, a topic scantily covered in the literature.

Methods

Two hundred seventy-one caregivers were recruited. Each completed the Affiliate Stigma Scale, Caregiver Burden Inventory, Taiwanese Depression Questionnaire, Beck Anxiety Inventory, and 28-item World Health Organization Quality of Life questionnaire. The data were evaluated for internal consistency and concurrent validity, and they were analyzed using Rasch statistics and confirmatory factor analysis (CFA).

Results

CFA and Rasch analysis suggested that the Affiliate Stigma Scale contains three underlying unidimensional concepts (cognition, affect, and behavior). The three concepts had satisfactory internal consistency (α = 0.822–0.855) and concurrent validity (r = 0.290–0.628 with caregiver burden, 0.391–0.612 with depression, 0.367–0.467 with anxiety, and −0.590 to −0.365 with quality of life).

Conclusions

The Affiliate Stigma Scale is a promising instrument with sound psychometric properties for measuring affiliate stigma. Healthcare providers might want to use it to understand the caregivers’ perspectives and to design appropriate interventions to decrease their affiliate stigma.
Draft genome of the leopard gecko, Eublepharis macularius
Authors: Xiong Zijun , Li Fang , Li Qiye , Zhou Long , Gamble Tony , Zheng Jiao , Kui Ling , Li Cai , Li Shengbin , Yang Huanming , Zhang Guojie
Published: October 2016

Background

Geckos are among the most species-rich reptile groups and the sister clade to all other lizards and snakes. Geckos possess a suite of distinctive characteristics, including adhesive digits, nocturnal activity, hard, calcareous eggshells, and a lack of eyelids. However, one gecko clade, the Eublepharidae, appears to be the exception to most of these ‘rules' and lacks adhesive toe pads, has eyelids, and lays eggs with soft, leathery eggshells. These differences make eublepharids an important component of any investigation into the underlying genomic innovations contributing to the distinctive phenotypes in ‘typical' geckos.

Findings

We report high-depth genome sequencing, assembly, and annotation for a male leopard gecko, Eublepharis macularius (Eublepharidae). Illumina sequence data were generated from seven insert libraries (ranging from 170 to 20 kb), representing a raw sequencing depth of 136X from 303 Gb of data, reduced to 84X and 187 Gb after filtering. The assembled genome of 2.02 Gb was close to the 2.23 Gb estimated by k-mer analysis. Scaffold and contig N50 sizes of 664 and 20 kb, respectively, were compble to the previously published Gekko japonicus genome. Repetitive elements accounted for 42 % of the genome. Gene annotation yielded 24,755 protein-coding genes, of which 93 % were functionally annotated. CEGMA and BUSCO assessment showed that our assembly captured 91 % (225 of 248) of the core eukaryotic genes, and 76 % of vertebrate universal single-copy orthologs.

Conclusions

Assembly of the leopard gecko genome provides a valuable resource for future comptive genomic studies of geckos and other squamate reptiles.
Transient electromagnetic fields of a buried horizontal magnetic dipole
Authors: Swidinsky Andrei , Nabighian Misac
Published: October 2016

Electromagnetic surveys using a vertical transmitter loop are common in land, marine, and airborne geophysical exploration. Most of these horizontal magnetic dipole (HMD) systems operate in the frequency domain, measuring the time derivative of the induced magnetic fields, and therefore a majority of studies have focused on this subset of field measurements. We examine the time-domain electromagnetic response of a HMD including the electric fields and corresponding smoke rings produced in a conductive half-space. Cases of a dipole at the surface and buried within the earth are considered. Results indicate that when the current in the transmitter is rapidly switched off, a single smoke ring is produced within the plane of the vertical transmitter loop, which is then distorted by the air-earth interface. In this situation, the circular smoke ring, which would normally diffuse symmetrically away from the source in a whole space, is approximately transformed into an ellipse, with a vertical major axis at an early time and a horizontal major axis at a late time. As measured from the location of the transmitter, the depth of investigation and lateral footprint of such a system increases with burial depth. It is also observed that the electric field measured in the direction of the magnetic dipole only contains a secondary response related to the charge accumulation on any horizontal conductivity boundaries because the primary field is always absent. This field component can be expressed analytically in terms of a static and time-varying field, the latter term adding spatial complexity to the total horizontal electric field at the earth surface at early times. Applications of this theoretical study include the design of time-domain induction-logging tools, crossborehole electromagnetic surveys, underground mine expansion work, mine rescue procedures, and novel marine electromagnetic experiments.
An alternative formula for approximate extended Born inversion
Authors: Hou Jie , Symes William W.
Published: October 2016

Various modifications of reverse time migration (RTM) provide asymptotic inverses to the subsurface offset extended Born modeling operator for constant-density acoustics. These approximate inverses have the same quality (asymptotic accuracy) as do generalized Radon transform pseudoinverses, but they can be computed without any ray tracing whatsoever. We have developed an approximate inverse of this type whose additional computational cost, above that of subsurface offset extended RTM, is negligible.
Applying modern interpretation techniques to old hydrocarbon fields to find new reserves: A case study in the onshore Gulf of Mexico, USA
Authors: Hulsey Josiah , Gani M. Royhan
Published: October 2016

This study shows how the use of current geological investigative techniques, such as sequence stratigraphy and modern seismic interpretation methods, can potentially discover additional hydrocarbons in old fields that were previously considered depleted. Specifically, we examine the White Castle Field in South Louisiana, which has produced over 84.1 million barrels of oil and 63.1 billion cubic feet of gas but retains additional recoverable hydrocarbons. The field has pay sections ranging from late Oligocene to late Miocene. The upper Oligocene to early Miocene package, which was underexploited and understudied during the previous exploitation phase, contains three primary reservoirs (Cib Haz, MW, and MR). During most of the late Oligocene, the White Castle Salt Dome was located in a minibasin on the continental slope. The Cib Haz and MW reservoirs were deposited in this minibasin and offer great exploitation potential. The Cib Haz interval is an amalgamation of slumped shelfal limestones, sandstones, and shales interpreted to represent a lowstand systems tract (LST). The MW comprises a shelf-edge delta deposit that is also interpreted as part of a LST. The MR reservoir is interpreted as an incised valley fill located in the continental shelf that was deposited during a lowstand of sea level after the minibasin was filled. Finally, it appears that the minibasin acted as a self-contained hydrocarbon system during the late Oligocene, suggesting the possibility of a shale play. In this study, several new areas of interest are revealed that could contain economical amounts of hydrocarbons.

Testing the General Validity of the Heckscher-Ohlin Theorem
Authors: Bernhofen Daniel M. , Brown John C.
Published: October 2016

We exploit Japan's mid-nineteenth century transition from autarky to open trade to test Alan Deardorff's (1982) seminal and parsimonious autarky price formulation of the Heckscher-Ohlin theorem. Factor price data from Japan's late autarky period impose a refutable restriction on Japan's factor content of trade. Our data are constructed from many historical sources, including a major Japanese survey of agricultural techniques and a rich set of nineteenth century comparative cost studies. Evaluating Japan's factor content of trade during 1865–1876 under alternative theoretical assumptions about technology, we provide robust evidence in favor of the Heckscher-Ohlin hypothesis.

Bid Takers or Market Makers? The Effect of Auctioneers on Auction Outcome
Authors: Lacetera Nicola , Larsen Bradley J. , Pope Devin G. , Sydnor Justin R.
Published: October 2016

Auction design has been studied extensively; however, within a given design, does the process of how an auction is conducted matter as well? We address this question by looking for heterogeneity in the performance of auctioneers in English auctions. We analyze over 850,000 wholesale used car auctions and find significant differences across auctioneers in outcomes for otherwise similar cars. The performance heterogeneities are stable across time and correlate with subjective evaluations by the auction house. We discuss the mechanisms driving differential performance and find evidence suggesting a role for tactics that generate bidder excitement or urgency. (JEL D44, D82, L62)
An Alternative to Signaling: Directed Search and Substitution
Authors: Levy Matthew , Szentes Balázs
Published: October 2016

This paper analyzes a labor market, where: workers can acquire an observable skill at no cost, firms differ in unobserved productivity, workers' skill and firms' productivity are substitutes, and firms' search is directed. The main result is that, if the entry cost of firms is small, no worker acquires the skill in the unique equilibrium. For intermediate entry costs, a positive measure of workers obtain the skill, and the number of skilled workers goes to one as entry costs become large. Welfare is highest when the entry cost is high. (JEL D21, D24, D82, D83, J24)

We report the results of an experiment that investigates free riding in the accumulation of durable public goods. We consider economies with reversibility, where contributions can be positive or negative; and economies with irreversibility, where contributions are nonnegative. Aggregate outcomes support the qualitative predictions of the Markov Perfect Equilibria (MPE) characterized in Battaglini, Nunnari, and Palfrey (2014): steady state levels of public good are lower with reversibility than irreversibility; accumulation is inefficiently slow; and the public good is under-provided in both regimes. On the other hand, public good levels are higher than MPE, and some evidence of history dependence is detected. (JEL C91, H41)
Achieving Efficiency in Dynamic Contribution Games
Authors: Cvitanić Jakša , Georgiadis George
Published: October 2016

We analyze a game in which a group of agents exerts costly effort over time to make progress on a project. The project is completed once the cumulative effort reaches a prespecified threshold, at which point it generates a lump-sum payoff. We characterize a budget-balanced mechanism that induces each agent to exert the first-best effort level as the outcome of a Markov perfect equilibrium, thus eliminating the free-rider problem. We also show how our mechanism can be adapted to other dynamic games with externalities, such as strategic experimentation and the dynamic extraction of a common resource. (JEL C73, D62, D82, Q31)
The Byzantine wall of Dinos Christianopoulos. A lost Palaiologan gatehouse in Thessaloniki.
Authors: ΘΕΟΧΑΡΗΣ Γιάννης
Published: October 2016

Στο άρθρο ταυτίζεται ένα χαμένο βυζαντινό μνημείο της Θεσσαλονίκης (απεικονισμένο στην Topographie de Thessalonique του Oreste Tafrali) με έναν βυζαντινό τοίχο, την περιγραφή του οποίου οφείλουμε στον ποιητή Ντίνο Χριστιανόπουλο. Ο εξεταζόμενος τοίχος αποτελούσε το μέτωπο του πυλώνα μιας άγνωστης μονής, η οποία βρισκόταν βόρεια της Αγίας Σοφίας και νότια της Εγνατίας. Ο τοίχος, αν και είχε κηρυχθεί προστατευόμενο μνημείο το 1926, κατεδαφίστηκε πιθανότατα το 1960. Από αυτό το χαμένο μνημείο προέρχεται ένα ζωγραφικό έργο μεγάλων διαστάσεων με την απεικόνιση του Χριστού, το οποίο σήμερα φυλάσσεται στο Αγίασμα του Αγίου Ιωάννη Προδρόμου, νότια της Αγίας Σοφίας. Το έργο αυτό, άλλοτε γνωστό στην πόλη ως ο «Μέγας Σωτήρ», φαίνεται πως διατηρεί ένα βυζαντινό στρώμα.
Περί της ιστορίας του γρηγοριάτικου κελιού του Αγίου Τρύφωνα στις Καρυές Αγίου Όρους και του τοιχογραφικού του διάκοσμου
Authors: ΜΕΡΤΖΙΜΕΚΗΣ Νικόλαος , ΣΙΩΜΚΟΣ Νικόλαος
Published: October 2016

Η ιστορική διαδρομή του κελιού του Αγίου Τρύφωνα στις Καρυές του Αγίου Όρους ανιχνεύεται μέσα από ιστορικές μαρτυρίες και αρχαιολογικά δεδομένα. Παράλληλα, παρουσιάζεται ο τοιχογραφικός διάκοσμος του παρεκκλησίου του, που χρονολογείται στο β΄ μισό του 18ου αιώνα, σίγουρα μετά το 1773, και συνδέεται με καλλιτεχνικά εργαστήρια που δραστηριοποιούνται στο Άγιον Όρος.
Λείψανα, θαύματα και ευλογίες : η αρχαιολογία της «λατρείας» τοπικών άγιων
Authors: ΦΩΣΚΟΛΟΥ Βίκυ Α.
Published: October 2016

Το άρθρο αποτελεί εκτενέστερη μορφή εισήγησης στην ημερίδα του 32ου Συμποσίου Βυζαντινής και Μεταβυζαντινής Αρχαιολογίας και Τέχνης της Χριστιανικής Αρχαιολογικής Εταιρείας. Στόχος της μελέτης είναι η παρουσίαση των υλικών μέσων και πρακτικών, των σημείων και συμβόλων που συντελούν στην ανάδειξη τοπικών αγίων και η σημασία που αποκτά η λατρεία τους στο πλαίσιο των τοπικών κοινωνιών. Επιπλέον, διερευνάται ο ρόλος των ιστορικών συνθηκών στη διαμόρφωση και ανάπτυξη των τοπικών λατρειών και αναζητείται κατ’ επέκταση μια τυπολογία των τοπικών αγίων σε κάθε ιστορική περίοδο του Βυζαντίου.
Ανάγλυφα εικονίδια Αγίων στις παλαιολόγειες επενδύσεις εικόνων της μονής Βατοπεδίου. Σχέσεις γλυπτικής και μικρογλυπτικής.

Στις υστεροβυζαντινές επενδύσεις εικόνων που διασώθηκαν στην μονή Βατοπεδίου του Αγίου Όρους, πρωτεύουσα θέση κατέχουν εικονίδια με προτομές αγίων. Τα ανάγλυφα αυτά εικονίδια, τα κατασκευασμένα πάνω σε αργυρά ελάσματα, που διακοσμούν τα πλαίσια επενδύσεων, προσφέρουν την δυνατότητα προσέγγισης της θρησκευτικής εικονιστικής γλυπτικής στην εποχή των Παλαιολόγων, της οποίας δεν σώζονται ικανά έργα. Από την μελέτη τους διαπιστώνεται ότι η μικρογλυπτική ακολουθεί τάσεις ανάλογες με την βυζαντινή γλυπτική και έτσι μπορεί κανείς να προσεγγίσει την δεύτερη και μέσω της πρώτης.
Middle Byzantine chafing dishes from Argolis.

Τα αυτοθερμαινόμενα σκεύη, γνωστά στην ελληνική βιβλιογραφία ως «σαλτσάρια», συνιστούν ένα σύνθετο σκεύος της μεσοβυζαντινής περιόδου. Εμφανίζονται τόσο σε λευκό όσο και σε ερυθρό πηλό, με κυρίαρχη την παράκτια και αστική διασπορά στο χώρο της κεντρικής και ανατολικής Μεσογείου. Στην Αργολίδα και κυρίως στο Άργος, έχουν έως τώρα καταγραφεί 53 δείγματα που στην πλειονότητά τους φέρουν ομοιότητες με αντίστοιχα δείγματα από την Κόρινθο, την Αθήνα και τη Θήβα και θα μπορούσαν να χρονολογηθούν, βάσει παραλλήλων, κυρίως στον 10ο-11ο αιώνα. Θα απευθύνονταν πιθανώς σε μέλη της τοπικής ελίτ, συνιστώντας μια μαρτυρία για πιο «εξελιγμένες» διατροφικές συνήθειες στη βυζαντινή περιφέρεια.
Δημιουργία Θεατρικής Ομάδας ΑΜΕΑ: Το παράδειγμα του Δήμου Πετρούπολης
Authors: Κυριάκου Κατίνα-Ευαγγελία
Published: October 2016

Στην εισήγηση γίνεται αναφορά της παιδαγωγικής αξίας της δραματικής τέχνης στην ολοκληρωμένη καλλιέργεια των ατόμων σε όλες τις βαθμίδες και σε όλες τις κατηγορίες της εκπαίδευσης (γενικής και ειδικής εκπαίδευσης). Θα παρουσιαστούν τα στάδια-βήματα που ακολουθήθηκαν στο Τμήμα Ατόμων Με Ειδικές Ανάγκες (ΑΜΕΑ) του Δήμου Πετρούπολης ώστε να δημιουργηθεί μια θεατρική ομάδα από όλα τα μέλη της. Θα γίνει αναφορά στη δημιουργία του θεατρικού έργου που γράφτηκε πάνω στα συγκεκριμένα άτομα ώστε να είναι απόλυτα προσαρμοσμένο στις ικανότητές τους, αλλά και στον τρόπο που εισήχθησαν οι εθελοντές στη διαδικασία της παράστασης. Τέλος θα επισημανθεί η καθοριστική σημασία που έχει η «προσαρμογή» του έργου στο τελικό αποτέλεσμα, γεγονός που επιβεβαιώθηκε από τον μεγάλο αριθμό συμμετοχής ΑΜΕΑ πάνω στη σκηνή κατά την υλοποίηση της παράστασης. Η παράσταση, συνδύασε την τέχνη του θεάτρου, του χορού και της μουσικής με σκοπό να τονίσει την ανάγκη έκφρασης των παιδιών επικεντρώνοντας σε δύο κύρια στοιχεία: (i) Το κοινωνικό μήνυμα της ισότητας και (ii) στην ανάδειξη της εσφαλμένης βεβαιότητας του δεδομένου στη ζωή των ανθρώπων.
Διαφοροποίηση στρατηγικών διδασκαλίας ανάλογα με το περιεχόμενο στα μαθήματα των φυσικών επιστημών
Authors: Στεφανίδης Κωνσταντίνος , Στεφανίδης Νικόλαος
Published: October 2016

Υπάρχει πληθώρα εννοιών, σχετικά με τον σχεδιασμό και την οργάνωση της διδασκαλίας, στην Ελληνική και διεθνή βιβλιογραφία, όπως διδακτική μέθοδος, στρατηγική διδασκαλίας, μέθοδος διδασκαλίας κ.α.  Αν και υπάρχουν κάποιες διαφορές μεταξύ τους, η πληθώρα των όρων καθιστά δύσχρηστη την επιλογή στρατηγικών, για το σχεδιασμό και υλοποίηση της διδασκαλίας. Στην παρούσα  μελέτη προσπαθούμε να παρουσιάσουμε ένα σχήμα (μοντέλο), το οποίο θα βοηθήσει το σχολιασμό και το σχεδιασμό μιας διδασκαλίας στα μαθήματα των φυσικών επιστημών. Το σχήμα αυτό είναι ένας δισδιάστατος πίνακας. Η μία διάσταση αποτελείται από τους βασικούς πυλώνες περιεχομένου στα παραπάνω μαθήματα, που είναι: οι έννοιες (φαινόμενα, φυσικά μεγέθη, νόμοι, θεωρίες, ...). Η δεύτερη διάσταση περιλαμβάνει τα κριτήρια με τα οποία κατηγοριοποιούμε τις στρατηγικές διδασκαλίας, τα οποία είναι: η αλληλεπίδραση στην τάξη, η ροή της πληροφορίας και η εποπτεία που χρησιμοποιείται στη διδασκαλία. Το παραπάνω σχήμα θα διευκολύνει μια συζήτηση για τις στρατηγικές διδασκαλίας που πρέπει ή συνήθως χρησιμοποιούνται από τους εκπαιδευτικούς στη διδασκαλία των μαθημάτων των φυσικών επιστημών για μαθητές με ή χωρίς μαθησιακές δυσκολίες, αδιακρίτως στη Β/θμια εκπαίδευση.

Στην παρούσα εργασία ερευνήσαμε το παιδικό ιχνογράφημα  ως μέσο έκφρασης παιδιών πρώτης σχολικής ηλικίας.

Σε δείγμα 30 μαθητών Α΄ τάξης δημοτικού σχολείου ( ανάμεσά τους και 7 μαθητές που παρακολουθούν Τμήμα Ένταξης )  συγκρίναμε τα ιχνογραφήματα της οικογένειάς τους  ως προς το φύλο τους, το μορφωτικό  επίπεδο των γονέων τους , την ολοκλήρωση των μορφών της ζωγραφιάς τους, την εγγύτητα των μελών της οικογένειας, τις απαντήσεις τους στις 6 τυποποιημένες ερωτήσεις  του πρωτοκόλλου  και τέλος συγκρίναμε τις ζωγραφιές των παιδιών τυπικής και ειδικής εκπαίδευσης.

Η διάρθρωση της εργασίας έχει ως εξής: ορισμός του παιδικού ιχνογραφήματος, παρουσίαση δημοσιευμένων ερευνών στον Ελλαδικό χώρο με θέμα το ιχνογράφημα  και τα αποτελέσματά τους και τέλος η δική μας έρευνα με τα ερωτήματα που θέσαμε, τα ευρήματα και τα συμπεράσματά μας.
