Identification of Enterprise Social Network (ESN) Group Archetypes in ESN Analytics: Metrics Selection and Case Application
Venue: Australas. J. Inf. Syst.
Year: 2020

With the proliferation of Enterprise Social Networks (ESN) the measurement of ESN activity becomes increasingly relevant. The emerging field of ESN analytics aims to develop metrics and models to measure and classify user activity to support organisational goals and outcomes. In this paper we focus on a neglected area of ESN analytics, the classification of activity in ESN groups. We engage in explorative research to identify a set of metrics that divides an ESN group sample into distinct types. We collaborate with Sydney based service provider SWOOP Analytics who provided access to actual ESN meta data describing activity in 350 groups across three organisations. By employing clustering techniques, we derive a set of four group types: broadcast streams, information forums, communities of practice and project teams. We collect and reflect on feedback from ESN champions in fourteen organisations. For ESN analytics research we contribute a set of metrics and group types. For practice we envision a method that enables group managers to compare aspirations for their groups to embody a certain group type, with actual activity patterns.
Access and Barriers to Education for Ghanaian Women and Girls
Year: 2008

As has been aptly stated in the 1995 United Nations Fourth World Conference on Women (UN, 1995) in Beijing, the girl child today is the woman of tomorrow. The skills, ideas, and energy of the girl child are vital for full attainment of the goals of equality, development, and peace. For the girl child to develop her full potential, she needs to be nurtured in an enabling environment, where her spiritual, intellectual, and material needs for survival, protection, and development are met and equal rights safeguarded. In the Ghanaian case, especially the limited education women receive could be detrimental to social development needs of women and girls, hence the focus of this paper, which add some important perspectives to the literature in the area.
Methamphetamine induces abnormal sperm morphology, low sperm concentration and apoptosis in the testis of male rats
Venue: Andrologia
Year: 2011

Methamphetamine has been reported to be an important drug in the field of reproductive toxicology. The aim of this study was to investigate the effects of methamphetamine administrations on sperm morphology, sperm concentration and apoptotic activity inside seminiferous tubule in male rats. Rats were administered a dose of 8 mg kg 1, intraperitoneally (IP) for acute group and a dose of 4 mg kg 1, IP, once daily for 14 days for sub acute group. Percentage of normal sperm morphology was decreased in acute group when compared with control. Total numbers of sperm count were significantly decreased in acute and sub acute groups. Apoptotic activities were most abundant in the seminiferous tubules of acute treated animals with a highly significant increase in the number of apoptotic cells per tubule. Those effects of methamphetamine seem to be dose dependent. The results suggest that methamphetamine not only works as drug of abuse in central nervous system, but also in gametogenesis of males.
Compose Like Humans: Jointly Improving the Coherence and Novelty for Modern Chinese Poetry Generation
Venue: 2020 International Joint Conference on Neural Networks (IJCNN)
Year: 2020

Chinese poetry is an important part of worldwide culture, and classical and modern sub branches are quite different. The former is a unique genre and has strict constraints, while the latter is very flexible in length, optional to have rhymes, and similar to modern poetry in other languages. Thus, it requires more to control the coherence and improve the novelty. In this paper, we propose a generate retrieve then refine paradigm to jointly improve the coherence and novelty. In the first stage, a draft is generated given keywords (i.e. topics) only. The second stage produces a "refining vector" from retrieval lines. At last, we take into consideration both the draft and the "refining vector" to generate a new poem. The draft provides future sentence level information for a line to be generated. Meanwhile, the "refining vector" points out the direction of refinement based on impressive words detection mechanism which can learn good patterns from references and then create new ones via insertion operation. Experimental results on a collected large scale modern Chinese poetry dataset show that our proposed approach can not only generate more coherent poems, but also improve the diversity and novelty.
Effect of crude extracts and purified compounds of Alpinia galanga on nutritional physiology of a polyphagous lepidopteran pest, Spodoptera litura (Fabricius)
Venue: Ecotoxicology and environmental safety
Year: 2019

Secondary plant metabolites play an important role in providing protection to plants against herbivore insect pests. Keeping in view the increasing importance of biopesticides, the crude extracts from different plants are being investigated for insecticidal activities. Alpinia galanga, a medicinal plant belonging to family Zingiberaceae exhibits a wide range of biological activities. In the present study, crude extracts of A. galanga and its purified compounds i.e. 1' acetoxychavicol acetate and galangin were evaluated for their effect on various nutritional parameters of Spodoptera litura (Fab. All the extracts exhibited a significant influence on relative growth and consumption rates as well as efficiency of conversion of ingested and digested food. Ethyl acetate extract was found to be the most effective causing significant reduction in values of RGR, RCR, ECI and ECD of S. litura larvae in comparison to control larvae. The highest concentration of the ethyl acetate extract (2500 ppm) resulted in 44.95% 10.99% 38.08% and 37.04% decrease respectively in RGR, RCR, ECI and ECD in comparison to control. The purified compounds also showed inhibitory effects on various nutritional parameters. 1' Acetoxychavicol acetate was found to be more effective in comparison to galangin.
Discussion on the Impact of Sino US Trade War on Taiwanese Manufacturing
Venue: International Journal of Business and Management
Year: 2019

When US President Donald Trump signed the Section 301 Investigation in March 2018, the Sino US trade war intensified, exerting a great impact on the global economy. The Trump Administration recently has piled up the economic and trade pressure on China, while China seeks to resort to the WTO dispute settlement mechanism and break the siege imposed by the trade war through the "Belt and Road Initiative" US launched a trade war against China due mainly to the huge trade deficit with China, and the trade frictions between the U.S. and China have caused turbulence on the Asian and global industrial chains. Therefore, by analyzing the recent trade conflicts between the U.S. and China and the responses given by both respectively, this paper explores the possible impact on Taiwan's manufacturing and its potential response.
Flexible superhydrophobic SERS substrates fabricated by in situ reduction of Ag on femtosecond laser written hierarchical surfaces
Year: 2018

The ability to fingerprint a few molecules via surface enhanced Raman scattering (SERS) continues to be of considerable utility in diverse fields encompassing physics, chemistry, materials sciences, nanotechnology, biomedicine, and environmental engineering. However, the development of facile and low cost approaches towards the fabrication of flexible substrates with very high SERS signal enhancement remains a challenge. Compared to conventional plasmonic based sensors, a superhydrophobic plasmonic surface provides the combined advantage of concentration enrichment of solute molecules, the fourth power dependent localized electric field enhancement as well as the enhanced light scattering on rough surface. We demonstrate here a method to fabricate flexible SERS substrates by replicating laser written patterns created on polymethylmethacrylate (PMMA) onto a soft elastomer, namely polydimethylsiloxane (PDMS) followed by in situ reduction of silver nanoparticles on the surface. Laser writing of structures is fluence dependent and leads to substantial enhancement of Raman signals compared to a conventional plasmonic surface. Our fabricated surfaces provide a limit of detection of eight femtomolar for Rhodamine 6G upon 532 nm resonance excitation; an enhancement factor of ~1010 is achieved for methyl orange. Studies of how water droplets spread on our laser written surfaces indicate a fluence dependent enhancement in apparent contact angle with a concomitant increase in the contact angle hysteresis (CAH) Most significantly, our replicated patterns exhibit lotus effect (superhydrophobic surface with ultra low contact angle hysteresis) that upon reduction of silver nanoparticles, exhibit superhydrophobicity with high contact angle hysteresis (rose petal effect) Our findings offer fresh opportunities for expanding the applicability of the SERS technique via superhydrophobic flexible plasmonic nanostructures.
The Current Situation and the Countermeasures of the Art Education in a Rural Junior Middle School
Year: 2007

The main problems existing in the art education of a rural junior middle school are as follows: the school unilaterally places undue emphasis on the proportion of the graduates entering schools of a higher grade and looks down upon the art education,the art teaching equipment is simple, the teaching patterns and methods are outdated,the teachers' academic credentials and their professional knowledge are somewhat lower,the curriculum reform ideas are also weaker.In order to solve these problems,the responsible department leader should attach importance to art education,heighten aesthetic education in a rural junior middle school,beautify the educating students environment,and push the aesthetic education forward.The teachers should bring out the rural source materials,better their own professional and cultural qualities,analyse the new curriculum standard,explore new methods and optimize the art teaching structure.
Enterotoxigenic coagulase positive Staphylococcus in milk and milk products, lben and jben, in northern Morocco.
Venue: Journal of infection in developing countries
Year: 2009

The aim of this research was to determine the prevalence of enterotoxin genes (sea seo) in Coagulase Positive Staphylococcus (CPS) isolated from unpasteurized milk and milk products. These results were compared with the results obtained by using the detection kit SET RPLA for the specific detection of staphylococcal enterotoxins (SEA SED) METHODOLOGY Eighty one samples of milk and milk products were analyzed for the presence of Staphylococcus strains. Forty six coagulase positive Staphylococcus isolates were tested for the production of staphylococcal enterotoxins (SEA SED) by using the reversed passive latex agglutination method. The strains were also tested for the presence of se genes (sea seo) by polymerase chain reaction.  One or more classical enterotoxin products (SEA SED) were observed in 39% of the strains tested, while se genes were detected in 56.5% SEA and sea were most commonly detected. For newly discovered se genes among CPS isolates tested in this study, except the seh gene which was revealed in four isolates (8.7 none of the strains harbored any of the other se genes (see, seg, sei, sej, sek, sel, sem, seo and sen)  The finding of a pathogen such as staphylococci producing SEs and containing se genes in milk and milk products in northern Morocco may indicate a problem for public health in this region. The presence of enterotoxigenic strains in food does not always necessarily mean that the toxin will be produced. For that reason, the combination of both methods (RPLA and PCR) is a guarantee for success in diagnostic analysis tests.
For a sequence of irreducible aperiodic reversible Markov chains with relaxation times
Year: 2016

A sequence of Markov chains is said to exhibit (total variation) cutoff if the convergence to stationarity in total variation distance is abrupt. We consider reversible lazy chains. We prove a necessary and sufficient condition for the occurrence of the cutoff phenomena in terms of concentration of hitting time of "worst" (in some sense) sets of stationary measure at least a, for some a (0, 1) We also give general bounds on the total variation distance of a reversible chain at time t in terms of the probability that some "worst" set of stationary measure at least a was not hit by time t. As an application of our techniques we show that a sequence of lazy Markov chains on finite trees exhibits a cutoff iff the product of their spectral gaps and their (lazy) mixing times tends to
Influences of Diamond Material on Heat Dissipation Capabilities of Helical Slow Wave Structures
Venue: IEEE Transactions on Electron Devices
Year: 2019

From theoretical calculations, simulations, and emulations, as well as laboratory testing, we evaluated the influences of both diamond and diamond film coated support rods, as well as diamond film coated helices, on the heat dissipation capabilities of slow wave structures (SWSs) A comparison between the experiment and simulation data shows that the computer simulation results are in good agreement and offer an important reference for the application of diamond in SWSs. An expression for the coefficient of thermal conductivity for the helix material and for the support rod material indicates that the greater their value, the better the heat dissipation capability of the helical SWS. The simulation and emulation analysis results show that when the helix reaches the same temperature, SWSs made of diamond film coated support rods and helix are able to consume 20% 60% more heating power than normal SWSs. Similar to a purely diamond support rod, a diamond film coated helix and support rod are able to improve the heat dissipation capabilities of SWSs effectively. In experiments, we tested the heat dissipation capabilities of SWSs with their helix surfaces plated with high performance gold/copper films and BeO/BeN support rods. The experimental results agree well with the ANSYS simulation and emulation results.

Faire circuler les objets naturalistes au XVIIIe siecle. Jean Hermann comme intermediaire dans les echanges entre la France meridionale et l'espace germanique
Year: 2016

Le savant strasbourgeois Jean Hermann (1738 1800) s'est constitue au XVIIIe siecle un espace relationnel europeen de plus d'une centaine de correspondants dont il fait un large usage pour le commerce des specimens et des livres d'histoire naturelle qui figurent au sein de ses collections. Ses reseaux d'echanges sont marques par un fort tropisme franco germanique. A l'echelle nationale, le pole meridional de sa correspondance, qui comporte une dizaine de naturalistes tels que Philippe Isidore Picot de Lapeyrouse a Toulouse ou Pierre Joseph Amoreux a Montpellier, est secondaire en comparaison de Paris. Mais il est un observatoire privilegie des strategies d'echanges et de leur dimension spatiale. Elles sont definies par rapport a un territoire de collecte local qui met en jeu la notion de meridionalite associee aux specimens naturels. Les echanges entre la France meridionale et le monde germanique dessinent egalement un espace de circulation des objets, concu comme un espace de cooperation entre les naturalistes et quantite d'intermediaires. Le parcours des objets entre Montpellier et Strasbourg donne la mesure de la mobilisation des intermediaires occasionnels charges de leur transport. En raison de sa position a l'interface avec l'espace germanique et des missions plus etendues qui lui sont confiees, Jean Hermann fait figure d'intermediaire regulier et expert.

Provider perspectives on the integration of patient reported outcomes in an electronic health record
Venue: JAMIA open
Year: 2019

Integrating patient reported outcomes (PROs) into electronic health records (EHRs) can improve patient provider communication and delivery of care. However, new system implementation in health care institutions is often accompanied by a change in clinical workflow and organizational culture. This study examines how well an EHR integrated PRO system fits clinical workflows and individual needs of different provider groups within 2 clinics.  Medicine developed and implemented an EHR integrated PRO system within the orthopedics and oncology departments. We conducted interviews with 11 providers who had interacted with the system. Through thematic analysis, we synthesized themes regarding provider perspectives on clinical workflow, individual needs, and system features.  Our findings show that EHR integrated PROs facilitate targeted conversation with patients and automated triage for psychosocial care. However, physicians, psychosocial providers, and medical assistants faced different challenges in their use of the PRO system. Barriers mainly stemmed from a lack of actionable data, workflow disruption, technical issues, and a lack of incentives.  This study sheds light on the ecosystem around EHR integrated PRO systems (such as user needs and organizational factors) We present recommendations to address challenges facing PRO implementation, such as optimizing data collection and auto referral processes, improving data visualizations, designing effective educational materials, and prioritizing the primary user group.  PRO integration into routine care can be beneficial but also require effective technology design and workflow configuration to reach full potential use. This study provides insights into how patient generated health data can be better integrated into clinical practice and care delivery processes.
The IART System for Race Walking: Experience with World Class Olympic Race Walkers
Year: 2020

Race walking is a discipline in which the best chronometric performance is constrained by infringements. Currently, the judgment and training of race walkers is entrusted to subjective observations made by judges. In this paper, with the objective of supporting coaching and judging, we present a wearable inertial sensor system (IART) for the evaluation of performances and infringements in race walking. The system is composed of an inertial sensor positioned close to the center of mass of the subject and a management unit designed for coaches and judges. IART allows: (i) a step sequence classification according to the competition rules; (ii) a customized assessment of elite race walkers based on key performance and infringement indices. The system is experimentally validated in field conditions by nine world class Olympic race walkers. The results show that IART improves the current evaluation of step sequences and offers a meaningful support for the overall evaluation of the technical gesture.
Are Acquirers Efficiently Priced? Evidence from Subsequent Earnings Announcements
Year: 2019

We adopt a model free measure of long run abnormal returns, the subsequent earnings announcement period abnormal returns, to examine the price efficiency of acquirer stocks involved in mergers and acquisitions. We find strong evidence of both overreaction and underreaction. First, the market underreacts to acquirer valuation information. Overvalued acquirers earn lower returns at the announcement period as well as during the long run period following the announcement. Second, in deals involving public targets, the market underreacts to stock payment information, as both announcement period abnormal returns and long run returns are lower when stock is used to pay for acquiring public targets; in private deals, the market overreacts to stock payment information, as announcement period abnormal returns are higher if stock is paid for private targets but the long run returns are significantly lower. There is also evidence that the market incorporates information regarding asset relatedness mostly over the longer term. The overall evidence suggests that acquirers are not efficiently priced at the announcement period.
Dorsal Anterior Cingulate Cortex: A Bottom Up View.
Venue: Annual review of neuroscience
Year: 2016

The dorsal anterior cingulate cortex (dACC) has attracted great interest from neuroscientists because it is associated with so many important cognitive functions. Despite, or perhaps because of, its rich functional repertoire, we lack a single comprehensive view of its function. Most research has approached this puzzle from the top down, using aggregate measures such as neuroimaging. We provide a view from the bottom up, with a focus on single unit responses and anatomy. We summarize the strengths and weaknesses of the three major approaches to characterizing the dACC: as a monitor, as a controller, and as an economic structure. We argue that neurons in the dACC are specialized for representing contexts, or task state variables relevant for behavior, and strategies, or aspects of future plans. We propose that dACC neurons link contexts with strategies by integrating diverse task relevant information to create a rich representation of task space and exert high level and abstract control over decision and action.
