Published: June 2019

Motor imagery-based brain-computer interfaces (BCIs) use an individual’s ability to volitionally modulate localized brain activity, often as a therapy for motor dysfunction or to probe causal relations between brain activity and behavior. However, many individuals cannot learn to successfully modulate their brain activity, greatly limiting the efficacy of BCI for therapy and for basic scientific inquiry. Formal experiments designed to probe the nature of BCI learning have offered initial evidence that coherent activity across diverse cognitive systems is a hallmark of individuals who can successfully learn to control the BCI. However, little is known about how these distributed networks interact through time to support learning. Here, we address this gap in knowledge by constructing and applying a multimodal network approach to decipher brain-behavior relations in motor imagery-based brain-computer interface learning using magnetoencephalography. Specifically, we employ a minimally constrained matrix decomposition method -- non-negative matrix factorization -- to simultaneously identify regularized, covarying subgraphs of functional connectivity and behavior, and to detect the time-varying expression of each subgraph. We find that learning is marked by distributed brain-behavior relations: swifter learners displayed many subgraphs whose temporal expression tracked performance. Learners also displayed marked variation in the spatial properties of subgraphs such as the connectivity between the frontal lobe and the rest of the brain, and in the temporal properties of subgraphs such as the stage of learning at which they reached maximum expression. From these observations, we posit a conceptual model in which certain subgraphs support learning by modulating brain activity in networks important for sustaining attention. After formalizing the model in the framework of network control theory, we test the model and find that good learners display a single subgraph whose temporal expression tracked performance and whose architecture supports easy modulation of brain regions important for attention. The nature of our contribution to the neuroscience of BCI learning is therefore both computational and theoretical; we first use a minimally-constrained, individual specific method of identifying mesoscale structure in dynamic brain activity to show how global connectivity and interactions between distributed networks supports BCI learning, and then we use a formal network model of control to lend theoretical support to the hypothesis that these identified subgraphs are well suited to modulate attention.

Published: June 2019

Modality specific encoding habits account for a significant portion of individual differences reflected in functional activation during cognitive processing. Yet, little is known about how these habits of thought influence long-term structural changes in the brain. Traditionally, habits of thought have been assessed using self-report questionnaires such as the visualizer-verbalizer questionnaire. Here, rather than relying on subjective reports, we measured habits of thought using a novel behavioral task assessing attentional biases toward picture and word stimuli. Hypothesizing that verbal habits of thought are reflected in the structural integrity of white matter tracts and cortical regions of interest, we used diffusion tensor imaging and volumetric analyses to assess this prediction. Using a whole-brain approach, we show that word bias is associated with increased volume in several bilateral language regions, in both white and grey matter parcels. Additionally, connectivity within white matter tracts within an a priori speech production network increased as a function of word bias. These results demonstrate long-term structural and morphological differences associated with verbal habits of thought.
The effect of a virtual reality environment on gaze behaviour and motor skill learning
Authors: Harris David
Published: June 2019

Virtual reality (VR) systems hold significant potential for both training and experimentation purposes as they provide precise control over the environment and the possibility to untether tasks from their normal physical constraints. However, the artificial creation of depth in stereoscopic displays, and reduced availability of haptic information, may affect how visually-guided motor tasks are performed in the virtual world. If so, tasks learned in VR may be unrepresentative of real skills, and therefore unlikely to elicit positive transfer to the real-world. In Experiment 1 we tested whether learning a visually-guided motor skill (golf putting) in virtual reality could transfer to real-world improvements. Despite the perceptual limitations imposed by the virtual environment, training novice golfers in VR led to improvements in real putting that were comparable to real-world practice. Experiment 2 explored these effects in more skilled golfers, and examined changes in gaze behaviour (quiet eye) that resulted from the more immediate use of VR (i.e. as a tool for ‘warming up’). VR use was found to cause impairments to gaze control (quiet eye) and putting accuracy, when used immediately prior to real world putting. Overall, these findings demonstrate the potential for VR training, but also highlight that fundamental questions remain about how the altered perceptual environment of VR affects visually-guided skills.
Do Climate Changes Lead to Income Inequality? Empirical Study on the Farming Community in Malaysia

Published: June 2019

Changes in climatic factors have different impacts on different social groups. But the farmers are considered to be the most vulnerable group because of their direct and indirect dependency on climatic factors. This study aims to understand the nature of socioeconomic impacts of climatic changes on the farmers in Malaysia. A questionnaire survey was conducted on a sample of 198 paddy farmers in the Integrated Agricultural Development Area at North-West Selangor of Malaysia in 2009. Data were analyzed using descriptive statistics, ordinal scale and percentile. The study reveals that climatic changes have adverse impacts on agricultural productivity, profitability, income equality, employment, farmer’s health, and government subsidy policy. The Kuznets ratio and Gini coefficient indicate that there is highly unequal distribution of income. Climatic changes are contributing to the widening of this income gap, because poor farmers are affected more by the adverse effects of climatic changes. The current government subsidy policy is not found appropriate and adequate to support and encourage the farmers to adequately adapt to the climatic changes and to reduce the inequality among the farming community. The paper ends up with recommending some policy guidelines to counter adverse effects of climate change on income of paddy farmers in Malaysia.

Published: June 2019

Ensuring accountability in the public sector is a very crucial issue as it could lead to failures in governance, fraud, inefficacy, corruption as well as weak financial management. This study evaluated the state of present accountability practices among public sector employees from various Malaysian service schemes. Primary data were collected, using a questionnaire survey approach with 194 heads of departments in the Malaysian federal ministries. Data was collected in accordance with the perspective of 12 factors in accountability practices, using a five-point Likert scale. Factor analysis and descriptive statistics were utilized for data analysis. In addition, data reliability was checked by Cronbach’s alpha test; data normality was examined by Skewness and Kurtosis tests, and data validity was tested by using Kaiser-Meyer Olkin test and Barlett’s test. The findings show that 94.9% of the participants reported that they practised accountability within their departments. Nevertheless, the priority for these accountability factors varied according to the service schemes. In general, the perceived accountability practice was the highest within the group of the administrative scheme and the lowest among the employees under the accounting scheme. Moreover, the perceived accountability practice of the audit scheme was below the general average level. This findings of the study would help policy makers to take necessary steps to improve the practices of accountability in the public sector for creating a more dependable and efficient public sector in Malaysia.

Published: June 2019

Purpose: Sustainable food security at the household level is one of the emerging issues for all nations. It is expected that the patterns of household resilience factors and adaptation practices have a strong linkage with household food security. The aim of this study was to seek an effective technique of adaptation for food security and the required types of support for adaptation to food insecurity among the poor and low income households in Malaysia.Design/methodology/approach: This study was based on primary data that were collected in Jul-Oct 2012 through a questionnaire survey among 460 poor and low income households from the Pahang, Kelantan, and Terengganu states of Malaysia. The samples were selected from E-Kasih poor household database based on a two-stage cluster random sampling technique. The study considered household food security as household food availability and food accessibility, and ran ordinal regressions to find out the linkages of household food security with household resilience factors, adaptation practices, and expected support for adaptation to food security.Findings: The study concludes that several resilience factors and adaptation practices were statistically significant to household food security, and several external supports were statistically and significantly needed to ensure household food security. Therefore, to ensure sustainable household food security in Malaysia, the food security programs needs to be integrated with Sustainable Development Goals (SDGs) and climatic changes adaptation programs, and the involvement of relevant stakeholders are crucial.Originality/value: This study is a pioneer work based on primary data that empirically measured the linkages of household food security with household resilience factors, adaptation practices, and expected support for adaptation to food security in Malaysia. This study also discussed some issues related to the climate change linkage, which would help future climate change research. The findings of the study will be beneficial for all the stakeholders, including policy makers related to the food security and climate change adaptation.
Dynamics of Japan’s Industrial Production and Carbon Emissions: Causality, Long-Term Trend and Implications
Authors: Murad Wahid , Alam Md. Mahmudul , Islam Mazharul
Published: June 2019

While CO2 emissions from the residential and commercial sectors of Japan have increased significantly since 1990 the country‟s industrial emissions make up the largest share of those emissions. The historical CO2 emission performance data also indicate that the iron and steel, chemical, paper and pulp and cement were the top four largest industrial emitters, and these top four emitting industries contributed nearly two-third of the industrial sector‟s total CO2 emission amount during 1990-2015. Evidently, any appropriate efforts or strategies guided by an empirical investigation like this are expected to help Japan‟s industrial emitters move toward a more tolerable and less polluted carbon footprint, which is well-matched with the country‟s commitment to Kyoto Protocol. This study is thus an effort to empirically investigate the causality and long-run trend/relationship between Japan‟s industrial production and CO2 emissions and to propose some corporate environmental strategies using the econometric techniques of Vector Error Correction (VEC) and Granger causality. It found that there exists no Granger causality between Japan‟s industrial production and CO2 emissions in any direction. But the VEC estimation reveals that an increase in Japan‟s industrial production by 1% is associated with a 0.08% increase in the country‟s CO2 emissions. It also reveals that any disequilibrium between Japan‟s industrial production and CO2 emissions could take about 0.7 quarters for half of the error to be corrected for. The adjustment rate for Japan‟s industrial production is found to be positive but quite slow at the rate of 0.08% per year. Since Japan‟s CO2 emissions vis-à-vis its industrial production is found to have reached above the long-run equilibrium level, its industrial sector is expected to encounter with stricter government regulations requiring reduction of CO2 emissions to the targeted/equilibrium level in the future.

Self-Directed Learning for Learner Autonomy: Teachers' and Students' Perceptions
Authors: Gharti Luk
Published: June 2019

The research entitled Self-directed Learning for Learner Autonomy: Perceptions of Teachers and Students was carried out to explore the perceptions about Self Directed Learning (SDL) for Learner Autonomy (LA) and analyze the roles of teachers to engage students in SDL. Considering the objectives, the primary data was collected from five master level English Language Teaching (ELT) teachers and three groups of master level students from Pokhara, Kaski. The purposive non-random sampling procedure was used to select the participants. The study was conducted using in-depth interview and Focused Group Discussion (FGD) tools to collect data. The obtained data from the respondents were analyzed and interpreted using analytical and interpretative procedure. It is a new approach in language teaching and learning in Nepalese context though it has been practicing since earlier. The finding shows that all the respondents have positive perceptions and its great contribution for developing LA. SDL helps learners to achieve better achievement and effective learning. It helps teachers to find the necessary changes and increases motivation to the learners to learn. But because of student’s unawareness, time constraint, no inspirations of institutions, student’s false assumptions, lack of insight knowledge about SDL, etc are creating the challenges in its proper application. In the study, the teachers’ roles are facilitator, helper, and resource provider by creating different situation, encouraging, orientating, inspiring, using Information Communication Technology (ICT) and using multimodality in the classroom.
Integrated and Segregated Teaching of Language Skills: An Exploration
Authors: Gautam Pitamber
Published: June 2019

This article attempts to explore some existing dimensions of integrated and segregated approaches to teaching language skills along with their psychological and methodological foundations. The body of language is built out of various components of skills and aspects fitted together in a natural harmony. They are substantial elements for teaching and learning endeavour. But, nowadays there are serious arguments about whether to choose segregated or integrated approach for teaching language skills in an ESL/EFL classroom. Although the behavioural psychology and structural linguistics pleaded for segregated approach of teaching through Grammar Translation Method and Audio-lingual Method, the communicative movement supported by cognitive psychology and functional linguistics has a strong adherence to integrated approach in teaching language skills with a sole aim of attaining communicative competence. This article is entirely based on document analysis method, a major component of qualitative research design. The study arrived to conclude that the current communicative movement in foreign language teaching significantly stresses on integrated teaching of language skills. This approach of teaching was proposed in different language teaching methods and models. Among them, Content Based Instruction and Task Based Instruction are the two major methods introduced for integrated language teaching. Now, it has been inferred that integrated approach of language teaching is sure to pursue its hegemony at least for some decades unless a new powerful approach appears to challenge it.

Published: June 2019

There are various treatment approaches for treating Chiari type I malformation with syringomyelia. Despite various choices, consensus for one particular approach is lacking. The objective of this study is to find out the clinical and radiological outcome of standard posterior fossa decompression incorporating removal of C1 arch with lax duroplasty in such cases.

A retrospective study based on data acquired from a single tertiary center were analyzed. All cases who underwent posterior fossa decompression incorporating removal of C1 arch with lax duroplasty over a period of five years were included and their clinical and radiological progress were recorded during OPD follow up at 6 months.

Out of 21 cases, occipital headache with nape of neck pain was the predominant complaint accounting to 71% followed by sensory symptoms and motor weakness, 61% and 33% respectively. Pain resolved in 93%, weakness in 71% and sensory symptoms in 69% of the cases. Only one patient developed hydrocephalus requiring shunting. Radiological improvement of syringomyelia were documented in 76.1% of the patients. There was no mortality.

Posterior fossa decompression incorporating removal of C1 arch and lax duroplasty is a safe approach with good outcome in patients with Chiari I malformation with syringomyelia.

Published: June 2019

Situs in versus is a rare anomaly where there is reversal of the visceral organ location and usually associated with Kartagener syndrome and digestive, circulatory and respiratory diseases abnormalities. The lateralization of visceralorgans to a side is a feature of vertebrates and humans are externally symmetrical but internally asymmetrical. Normal anatomy imparts the heart to left and the liver to the right which is found not only in humans but also other animals. This case showed aqueduct stenos is with hydrocephalus with normal corpus callosum. The association of situs in versus with ciliary abnormalities and therefore is rarely associated with hydrocephalus, polycystic disease or retinal degeneration. PubMed search for situs in versus total is with hydrocephalus showed only 7 results with 3 of them in animal studies, one was not relevant and the rest in human. Hydrocephalus was present in only two studies, one of them cadaveric finding. The association with hydrocephalus is very rare and we present such a case report.
Unusual Complication of the Foramen Magnum Decompression
Authors: Narayana Sridhara , Teegala Ramesh
Published: June 2019

The pathophysiology of Chiari-Imalformation lies with the abnormal CSF flow across Foramen magnum and Foramen magnum decompression (FMD) restores this flow. However, recent data suggests that FMD itself can alter the CSF dynamics in an abnormal fashion resulting in raised intracranial pressure. We report such a case where FMD has led to the development of subdural hygroma and hydrocephalus. Patient was managed with VP shunt after a failed trial of re-exploration and burr hole drainage. The mechanism behind this complication is not clearly understood despite several hypotheses being proposed. Once established, management has to be individualized, based upon the clinical condition and location of CSF collection.

Modeling the return to consciousness after severe traumatic brain injury at a large academic level 1 trauma center
Authors: Winans Nathan J. , Liang Justine J. , Ashcroft Bradley , Doyle Stephen , Fry Adam , Fiore Susan M. , Mofakham Sima , Mikell Charles B.
Published: June 2019

OBJECTIVE

Severe traumatic brain injury (sTBI) carries significant morbidity and mortality. It remains difficult to counsel families on functional prognosis and plan research initiatives aimed at treating traumatic coma. In order to better address these problems, the authors set out to develop statistical models using retrospective data to identify admission characteristics that correlate with time until the return of consciousness, defined as the time to follow commands (TFC). These results were then used to create a TFC score, allowing for rapid identification of patients with predicted prolonged TFC.

METHODS

Data were reviewed and collected from medical records of sTBI patients with Glasgow Coma Scale (GCS) motor subscores ≤ 5 who were admitted to Stony Brook University Hospital from January 2011 to July 2018. Data were used to calculate descriptive statistics and build binary logistic regression models to identify admission characteristics that correlated with in-hospital mortality and in-hospital command-following. A Cox proportional hazards model was used to identify admission characteristics that correlated with the length of TFC. A TFC score was developed using the significant variables identified in the Cox regression model.

RESULTS

There were 402 adult patients who met the inclusion criteria for this study. The average age was 50.5 years, and 122 (30.3%) patients were women. In-hospital mortality was associated with older age, higher Injury Severity Score (ISS), higher Rotterdam score (head CT grading system), and the presence of bilateral fixed and dilated pupils (p < 0.01). In-hospital command-following was anticorrelated with age, ISS, Rotterdam score, and the presence of a single fixed and dilated pupil (p < 0.05). TFC was anticorrelated with age, ISS, Rotterdam score, and the presence of a single fixed and dilated pupil. Additionally, patients who sustained injuries from falls from standing height had a shorter average TFC. The 3 significant variables from the Cox regression model that explained the most variance were used to create a 4-point TFC score. The most significant of these characteristics were Rotterdam head CT scores, high impact traumas, and the presence of a single fixed and dilated pupil. Importantly, the presence of a single fixed and dilated pupil was correlated with longer TFC but no increase in likelihood of in-hospital mortality.

CONCLUSIONS

The creation of the 4-point TFC score will allow clinicians to quickly identify patients with predicted prolonged TFC and estimate the likelihood of command-following at different times after injury. Discussions with family members should take into account the likelihood that patients will return to consciousness and survive after TBI.

Anodization of titanium implants is accompanied by the formation of titanium oxide nanotubes improving osseointegration. An excessive fibroblast adhesion on the surface might lead to the formation of fibrous capsule resulting in implant rejection. In our research, we demonstrated that the adhesion activity of human dermal fibroblasts on anodized surface was not elevated, which is promising for the use of titanium with nanotube-layered surface for implantology.

This article aims to analyze the esoteric interpretation of the Qur'an written in Sundanese. The object of the study is theQuranul Adhimiof Haji Hasan Mustapa (1852-1930). Through the analysis of hermeneutics, this study shows that the local exegesis can not be assumed that it has the same character as the Malay-Indonesian exegesis. Indeed, it shows local creativity born out of the diversity of cultural backgrounds. It also shows the process of the dialogue between Sufism and the inner of Sundanese people in the frame of Qur'anic exegesis. This can be proven in three ways: the interpretation centered on the inner meaning, the use of natural metaphors, and the nuances of Sundanese literature. The significance of Mustapa 'sexegesis lies in the process of -indigenization of the Qur'an (Islam) to the characteristics of the local Islamic tradition through the work of Quranic exegesis. This work clearly indicates the local creativity in responding to the intellectual tradition of Sufism, especially the Sufi interpretation. Not only through metrical poetry, he also interprets mystical experiences through theexegesis.

Božja pravednost
Authors: Matijević Dalia
Published: June 2019

Svrha ovoga članka jest pružiti uvid u to do koje mjere naše poimanje koncepta dikaiosyne theou oblikuje način na koji sebe poimamo kao kršćane, koji predstavljaju Tijelo Kristovo i žive u svetosti. Pod snažnim utjecajem Poslanice Rimljanima razumijemo svetost kao življenje u pravilnom odnosu s Bogom, a pravednost kao praktičnu posljedicu tog odnosa. Svetost, kao unutarnja Božja priroda, očituje se kao Božja pravednost, koja se pak ostvaruje kroz Božje spasiteljsko djelovanje. Međutim, u svjetlu Krista i Njegove žrtvene smrti te uskrsnuća, relacijske i eshatološke dimenzije koncepta dikaiosyne theou nameću se kao presudne. Ovaj koncept stoji u samom središtu Pavlova evanđelja i pretpostavlja više slojeva značenja, a prije svega Božje otkupiteljsko i spasiteljsko djelovanje, ali također i Božju zavjetnu vjernost te restorativnu pravdu koja je dostupna svakome. Šira se perspektiva koncepta dikaiosyne theou otvara putem Isusove odanosti i poslušnosti Ocu pri ispunjavanju konačne svrhe spasenja. Za nas to znači život koji podrazumijeva trajnu transformaciju na sliku Boga i samoostvarenje kroz odnos s Njim te s bližnjima u eshatološkoj perspektivi. Kršćanska je etika duboko ukorijenjena u konceptu dikaiosyne theou, a kršćanski način života predstavlja njegov nezaobilazni praktični izričaj. Ljudi koji žive u autentičnoj kršćanskoj zajednici obilježeni su Božjom pravednošću koja se izražava kao kolektivna agape, pri čemu su progresivno preobražavani prisutnošću i djelovanjem Duha Svetoga te svjesno uranjaju u kontinuirani proces otkrivanja uvijek novih mogućnosti afirmiranja Božje pravednosti. Stoga, kršćanska je vjerska zajednica po svojoj naravi nužno inkluzivna.
Uvid u borbu nadbiskupa Desmonda Tutua protiv apartheida u Južnoj Africi
Authors: Kokobili Alexander
Published: June 2019

Ovaj članak razmatra ulogu koju je nadbiskup Desmond Tutu odigrao u borbi protiv rasizma i socio-političke nejednakosti koju je promicao sustav apartheida u Južnoafričkoj Republici. Tutu je često u svojim govorima i javnozagovaračkim istupima osuđivao apartheid te promicao jednakost, pomirenje i miran suživot svih Južnoafrikanaca. Ideologija apartheida je crncima u Južnoj Africi otuđila svako ljudsko dostojanstvo, što je u suprotnosti sa Svetim pismom u kojem piše: „Tako Bog stvori čovjeka na sliku svoju. Stvori ga na sliku Božju. Stvori ih kao muža i ženu“ (Postanak 1,27). Unatoč tome je 1948. godine bjelačka Nacionalna južnoafrička stranka ozakonila apartheid kao politički sustav i pritom dobila podršku Nizozemske reformirane crkve bez obzira na to što se radilo o primjeni etike koja je protivna kršćanstvu. Apartheid je u Južnoj Africi usvojen s ciljem da se bijela manjina pozicionira kao viša društvena klasa, dok je crnačkoj većini bilo oduzeto niz prava i povlastica. Desmond Tutu je bio jedan od malobrojnih kršćanskih vođa koji je u Africi utirao put crnačke teologije pri rušenju apartheida u Južnoj Africi. Tijekom njegove borbe protiv apartheida, Tutu nije poticao na nasilne prosvjede ili nerede, već je više pokušavao djelovati kroz svoje propovijedi i poticati javnost na sudjelovanje u aktivnostima koje su promicale nacionalno jedinstvo, ljubav i jednakost svih Južnoafrikanaca.

Asphalt concrete is highly used to construct pavement layers in the civil engineering field. It is defined as a complex medium composed of aggregates (inclusions), mortar (matrix) and air void. The mortar itself is a mixture of fillers, sand and bitumen. Furthermore, mortar is the phase that links the coarse aggregates. In general, fracture of asphalt concrete occurs within mortar or among aggregate-mortar interface. Therefore, two types of fracture can be identified, i.e., adhesive and cohesive damages. The first type is occurred among the interface of aggregate-mortar. The second is taken place within the mortar. This paper presents numerical investigations of the damage initiation and stiffness degradation within the asphalt concrete matrix. Numerical simulations were carried out to investigate, firstly, how damage is initiated and developed, and then, to simulate how cracks can be initiated and propagated within this material. Cohesive finite elements method was adopted to simulate fracture. For adhesive damage, the model was represented by one rectangular aggregate that is linked to the asphalt concrete thanks to a thin layer of the mortar. For cohesive damage, the model was considered as a thick layer of the mortar in between two coarse aggregates. The applied loading was derived from the speed of traffic vehicle. A comparative analysis between four mortars was conducted. The effect of loading and the type of mortar on damage initiation and stiffness degradation will be shown. Moreover, the initiation and propagation of cracks as function of loading and stiffness modulus will be illustrated.

Besides energy-efficiency, people also want train operation to be comfortable, punctual and parking precise. In this paper, a multi-objective model for automatic train operation in urban railway is proposed by unifying dimensions of different objectives firstly. This model is built by applying multi-objective decision with the penalty function, based on the analysis of train performance and its operation environment. Then a genetic algorithm is developed to solve this model and obtain the optimal recommended speed profiles. Thirdly, fuzzy controller is designed to achieve track recommended speed profiles. Finally, with the help of Matlab software, control effect is verified based on simulation. From the simulation results, it can be seen this strategy can meet the requirement of multi-objective, which are energy-saving, parking precisely, running punctually and comfort.
