Creating coherent incidental learning journeys on mobile devices through feedback and progress indicators

Timely and appropriate feedback and indicators of progress can motivate learners. Mobile learning poses a challenge to established instructional strategies with respect to delivering feedback and monitoring learner progress, particularly in informal and incidental learning occurring outside of formal structured learning environments. We argue that well-designed and managed feedback and progress indicators can offer guidance and a sense of structure to learners in the absence of a formal curriculum, accreditation or set outcomes. Furthermore, they can encourage casual users of mobile applications to move from fragmented learning episodes towards a more long term and reflective learning journey. In this paper we describe how we are developing feedback and progress indicators for the EU-funded MASELTOV project, which explores how smartphones can support language learning and social inclusion for recent immigrants to Europe. Presenting educational services and materials on mobile devices allows learning episodes to be incorporated into daily activities and schedules, to be accessed at times and in places that suit learners best. Feedback and progress indicators embedded into these services may motivate such an audience to reconceptualise fragmentary, ephemeral educational experiences into a more coherent, sustained learning journey. We describe how feedback and progress indicators have been used successfully in web-based and games-based learning, and our assessment of which types may best support incidental mobile learning and the challenges we face.
HPV in anal cancer Inﬂuence of human papillomavirus and p16 INK4a on treatment outcome of patients with anal cancer

Background: The purpose of this study was to evaluate HPV-DNA and p16 INK4a (p16) expression as prog- nostic markers for outcome in patients with anal cancer. Methods: From January 2000 to December 2011 a cohort of 105 anal cancer patients was treated with deﬁnitive chemoradiation at our institution. Tumor biopsies from 90 patients were analyzed for HPV-DNA by polymerase chain reaction and for p16 expression by immunohistochemistry. Results: Median follow-up was 48.6 months (range 2.8–169.1 months). HPV-DNA or p16-expression was found in 75 anal cancers each (83.3%), concordance was detectable in 70 tumors (77.8%). Signiﬁcantly improved overall survival (OS) [77.1% vs. 51.4%, p = 0.005], progression-free survival (PFS) [64.0% vs. 35.0%, p < 0.001] and improved local control [81.0% vs. 55.9%, p = 0.023] was found for concomitant
A NEW STRUCTURE FOR CURRENT-MODE CONTINUOUS TIME GM-C FILTERS

Abstract– In this paper a new structure for the MLF (Multi Loop Feedback) Gm-C group of filters is presented, granting the advantages of both current-mode and fully balanced topologies to the conventional structure of the group. The ability of the structure to perform even more transfer functions (Low pass and Band Pass) than other members of the group is proved. Methods of enabling the proposed structure to perform other popular transfer functions are also presented. The favorite feature of systematical generation of the structure facilitates its arrangement for any order. For practical comparison, a Butterworth 4–order LP filter with a cut-off frequency of 10MHz is designed in three different structures viz; the proposed one, the single-ended current mode, and fully balanced voltage mode. Simulation results show that the PSRR+,PSRR-,CMRR, Noise, THD, DR, consumed power (P) and Figure of Merit (FOM) of the new structure compared to its voltage mode counterpart are improved at least by factors of 36643, 59841, 4.75, 76, 2, 2.45, 1.17 and 509500, respectively. Compared to single ended current-mode type they are improved by factors of 40, 73, not defined, 1.3, 7.8, 150, 0.68 and 1763000, respectively. Although the above mentioned comparison, due to both the similarity of the used technology and the completeness of the results, is the most equitable one for the most definite conclusion, to further widen the extent of the comparison, the proposed structure is also compared with some other works yet assumed as its closet counterparts. This latter comparison also proves the certain superiorities of the proposed structure such that its FOM is from 8500 to 4512740 times larger than those of others. Closer tracking of the input signal at pass-band and more attenuation at stop-band are also achieved by this structure. These results strongly support the theoretical suggestions. Most favorably the much higher PSRR of the new structure makes it an extremely suitable choice for Mix-Mode (SystemOna Chip, SOC/SOI) applications where power supplies (and analog blocks) suffer severely from digital noise.
Agency Conflicts, Expropriation and Firm Value: Evidence from Securities-Market Regulation in China

In this study, we examine the wealth effects of regulatory changes intended to improve corporate governance by protecting minority shareholders from expropriation by controlling shareholders. Using data from publicly traded Chinese firms, we find that these new regulations significantly increased firm value, and that firms with weak governance disproportionately benefited relative to firms with strong governance. Our evidence provides new support for the theory of La Porta et al. (2002) that better investor protection results in higher firm valuations. It also is supportive of the theory of Glaeser, Johnson and Shleifer (2001) that securities-market regulation can create substantial value for minority shareholders in a country with weak judicial enforcement. Finally, it is consistent with Black and Kraakman (1996), who argue that, in rule-based civil-law countries, regulation in the form of simple “bright-line rules” is more effective than in the form of “broad standards. ”
Attitudes influence implicit racial face categorization in a perceptual task

Perceptual mechanisms have been proposed for the categorization of racial faces. Social cognitive mechanisms involved in the categorization of racial faces, however, remain unclear. The present study investigated whether and how attitudes influence racial face categorization by measuring reaction times to judge orientations of own-race or other-race faces. Study 1 showed that, in a task of judging orientations of Caucasian and Asian faces, European Americans responded faster to own-race (Caucasian) faces than to other-race (Asian) faces. Study 2 showed that Han Chinese responded faster to own-race (Han Chinese) faces than to other-race (Uigur Chinese) faces. In addition, we found that, in both experiments, own-race advantage in reaction times was eliminated by inducing negative attitudes toward own-race faces using a negative association priming procedure. Moreover, the mediation analysis in Study 2 showed that the priming effect was mediated by attitude bias toward own-race faces. Our findings provide evidence for categorization of racial faces in a perceptual, race-irrelevant task, which, however, is strongly modulated by attitudes toward target faces.
Leader-member exchange theory in higher and distance education

Unlike many other prominent leadership theories, leader-member exchange (LMX) theory does not focus on the specific characteristics of an effective organizational leader. Rather, LMX focuses on the nature and quality of the relationships between a leader and his or her individual subordinates. The ideal is for a leader to develop as many high-quality relationships as possible. This will lead to increases in subordinates’ sense of job satisfaction and organizational citizenship, as well as to increased productivity and attainment of organizational goals. LMX has been criticized for its potential to alienate some subordinates, failing to account for the effects of group dynamics and social identity, and failing to provide specific advice on how leaders can develop high-quality relationships. However, LMX has been heralded as an important leadership theory in higher and distance educational contexts because of its emphasis on promoting autonomy and citizenship, as well as its ability to complement and mediate transformational leadership styles. Recent authors have attempted to provide specific advice for leaders who want to learn how to build and capitalize on the high-quality relationships described by LMX theory.
CrowdIA

The increasing volume of text data is challenging the cognitive capabilities of expert analysts. Machine learning and crowdsourcing present new opportunities for large-scale sensemaking, but we must overcome the challenge of modeling the overall process so that many distributed agents can contribute to suitable components asynchronously and meaningfully. In this paper, we explore how to crowdsource the sensemaking process via a pipeline of modularized steps connected by clearly defined inputs and outputs. Our pipeline restructures and partitions information into "context slices" for individual workers. We implemented CrowdIA, a software platform to enable unsupervised crowd sensemaking using our pipeline. With CrowdIA, crowds successfully solved two mysteries, and were one step away from solving the third. The crowd's intermediate results revealed their reasoning process and provided evidence that justifies their conclusions. We suggest broader possibilities to optimize each component, as well as to evaluate and refine previous intermediate analyses to improve the final result.
feature Detecting minimal residual disease in multiple myeloma Challenges and prospects for the integration of novel approaches in clinical practice

relapse rates in multiple myeloma (MM) remain high, even in patients who achieve complete response (CR). Lower minimal residual disease (MRD) levels correlate strongly with longer progressionfree survival, however the accuracy of MRD detection is strongly dependent upon the sensitivity of the techniques used. This review presents available data on MRD assays and their potential value in tailoring MM treatment. Available research shows that depth of response as assessed with current MRD evaluation methods is a powerful predictor of outcome, and may be more important than the manner in which a deep response was achieved.

Assessing the impact of a future volcanic eruption on decadal predictions

Abstract. The likelihood of a large volcanic eruption in the future provides the largest uncertainty concerning the evolution of the climate system on the timescale of a few years, but also an excellent opportunity to learn about the behavior of the climate system, and our models thereof. So the following question emerges: how predictable is the response of the climate system to future eruptions? By this we mean to what extent will the volcanic perturbation affect decadal climate predictions and how does the pre-eruption climate state influence the impact of the volcanic signal on the predictions? To address these questions, we performed decadal forecasts with the MiKlip prediction system, which is based on the MPI-ESM, in the low-resolution configuration for the initialization years 2012 and 2014, which differ in the Pacific Decadal Oscillation (PDO) and North Atlantic Oscillation (NAO) phase. Each forecast contains an artificial Pinatubo-like eruption starting in June of the first prediction year and consists of 10 ensemble members. For the construction of the aerosol radiative forcing, we used the global aerosol model ECHAM5-HAM in a version adapted for volcanic eruptions. We investigate the response of different climate variables, including near-surface air temperature, precipitation, frost days, and sea ice area fraction. Our results show that the average global cooling response over 4 years of about 0.2 K and the precipitation decrease of about 0.025 mm day−1 is relatively robust throughout the different experiments and seemingly independent of the initialization state. However, on a regional scale, we find substantial differences between the initializations. The cooling effect in the North Atlantic and Europe lasts longer and the Arctic sea ice increase is stronger in the simulations initialized in 2014. In contrast, the forecast initialized in 2012 with a negative PDO shows a prolonged cooling in the North Pacific basin.
The Influence of Explicit, Implicit, and Contrastive Lexical Approaches on Pragmatic Competence: The Case of Iranian EFL Learners

Abstract Research literature suggests the positive role of lexical chunks and translation in teaching and learning pragmatics (Ketko, H. 2000. Importance of multi-word chunks in facilitating communicative competence and its pedagogic implications. The Language Teacher 24(12). 5–11; Rose, K. R. 1999. Teachers and students learning about requests in Hong Kong. In E. Hinkel (Ed.), Culture in second language teaching and learning, 167–180. Cambridge: Cambridge University Press. ). Accordingly, the present study aimed at investigating the influence of contrastive lexical approach (CLA), in comparison with explicit and implicit approaches, on Iranian EFL learners’ pragmatic competence. Sixty-three participants were randomly assigned to three treatment groups and received dissimilar instructional treatments for ten 30-minute sessions. A pretest-posttest equivalent-groups research design was carried out and pretest scores were used as the covariate in a one-way ANCOVA data analysis. CLA showed no significant advantage over the other two methods. Previous studies have often combined a contrastive method with explicit teaching. Confounding variables in this way may have made interpretation of results problematic. In the present research explicit and contrastive instructions were kept separate and no significant difference was found between the three treatments, although all instruction types enhanced the language learners’ pragmatic competence. As a result, a pragmatic teaching course is recommended which incorporates the useful teaching techniques and practices of these three approaches to teaching pragmatic competence.
Autonomous Decentralized Flow Control in High-Speed Networks with Inhomogeneous Configurations

SUMMARY Recent growth in computer communications has led to an increased requirement for high-speed backbone networks. In such highspeed networks, the principle adopted for a time-sensitive flow control mechanism should be that of autonomous decentralized control. In this mechanism, each node in a network manages its local traffic flow only on the basis of the local information directly available to it, although it is desirable that the individual decisions made at each node lead to high performance of the network as a whole. In our previous studies, we have investigated the behavior of local packet flows and the global performance achieved when a node is congested, and proposed the diffusion-type flow control model. However, since we used a simple and homogeneous network model in the evaluation, the results cannot be generalized. In this paper, we propose an extension of the diffusion-type flow control model in order to apply it to networks with inhomogeneous configurations. We show simulation results for two cases: different propagation delays and multiple bottlenecks. Both results show that the proposed diffusion-type flow con
Magnetic field–induced pair density wave state in the cuprate vortex halo

Decoding the halo pattern Magnetic fields can cause the formation of vortices in a superconductor. In cuprate superconductors, the vortex cores are surrounded by “halos,” where the density of electronic states exhibits a checkerboard pattern. Edkins et al. used scanning tunneling spectroscopy to take a closer look into the halos. The results revealed that the patterns correspond to an exotic state called the pair density wave, in which the density of finite momentum Cooper pairs is spatially modulated. Science, this issue p. 976 Scanning tunneling spectroscopy reveals modulated density of finite-momentum Cooper pairs in vortex halos of Bi2Sr2CaCu2O8. High magnetic fields suppress cuprate superconductivity to reveal an unusual density wave (DW) state coexisting with unexplained quantum oscillations. Although routinely labeled a charge density wave (CDW), this DW state could actually be an electron-pair density wave (PDW). To search for evidence of a field-induced PDW, we visualized modulations in the density of electronic states N(r) within the halo surrounding Bi2Sr2CaCu2O8 vortex cores. We detected numerous phenomena predicted for a field-induced PDW, including two sets of particle-hole symmetric N(r) modulations with wave vectors QP and 2QP, with the latter decaying twice as rapidly from the core as the former. These data imply that the primary field-induced state in underdoped superconducting cuprates is a PDW, with approximately eight CuO2 unit-cell periodicity and coexisting with its secondary CDWs.
A randomized controlled study of intraperitoneal vs intraincisional infiltration of local anesthetic levobupivacaine for pain relief in post-laparoscopic hysterectomy cases

Introduction and Aim: Providing postoperative pain relief is a common acceptable practice in modern era. Multimodal combination methods are being used to reduce opioid-related side effects. We conducted a randomized study with 0.125% levobupivacaine in intraincisional infiltration vs intraperitoneal instillation for pain relief after laparoscopic hysterectomies. Materials and Method: In this randomized controlled study 90 patients of laparoscopic hysterectomy were selected. They were grouped as Group-C the control placebo, Group-I received local wound infiltration (intraincisional) of 20 ml solution of 0.125%, levobupivacaine while Group-P received 20 ml solution of 0.125%, levobupivacaine intraperitoneal space. Recording of post-surgical pain from 0 to 24 hours along with nausea and vomiting was done. Results: Post-operative pain was significantly lower and requirement butorphanol also less in intraincisional infiltration of 0.125% levobupivacaine in group -I (300±470µg)when compared to group-C and P (950±223, 600±502) in 1st 4 hours with significant p -value 0.000041 and in 24 hours group-C{783.33±415.45} group-I {466.67±503.09} and group-P {583.33±457.18} with significant p-value of 0.0013. Regarding opioid requirement in 1st-4 hours in group-C (90%) group-I only (30%) and group-P (60%), in 8-24 hours period in group-C (60%) compared to group-I(40%) and group-P(50%). Conclusion: Incisional infiltration of levobupivacaine is more effective than intraperitoneal instillation in controlling the post-operative pain. Keywords: Laparoscopic hysterectomy, Levobupivacaine, Local anesthetic, Post-operative pain Intraincisional infiltration, Intraperitoneal instillation
On passion and heavy work investment: personal and organizational outcomes

Purpose – The present research aimed to conceptually position passion for work as a predictor of HWI, as well as to assess the short and long-term influence of passion for work on workers' satisfaction, depression and turnover intentions. In addition, the paper tests whether the effects of passion for work were independent from those of work motivation. Design/methodology/approach – Hypotheses were tested in two field studies in work settings. The first study (n=2,393) was cross-sectional while the second study (n=335) used a prospective design. Findings – Harmonious passion was positively related to positive individual outcomes – higher work satisfaction, lower depression – and organizational outcomes – lower turnover intentions. Negative consequences – depression and turnover intentions – were positively related to obsessive passion. Furthermore, passion for work was found to be a distinct concept from work motivation as the above findings held even when controlling for work motivation. Research limitat.

ERDC/TN APCRP-CC-06, Effects of Turbidity on Fluridone Treatments for Curlyleaf Pondweed Contro

PURPOSE: A small-scale study was conducted to evaluate fluridone (1-methyl-3-phenyl-5-[3trifluoromethyl)phenyl]-4(1H)-pyridinone) efficacy under varying levels of turbidity when controlling curlyleaf pondweed (Potamogeton crispus L.). There is no information on the effect of turbidity on fluridone efficacy against curlyleaf pondweed. It is unknown if turbidity impacts aqueous fluridone concentrations in the water column, thereby lessening herbicide efficacy and reducing control, or whether turbid conditions create additional stress that could intensify herbicide effects, causing greater plant injury and deterioration.
The Optimal Culture Conditions Affecting the Mycelial Growth and Fruiting Body Formation of Paecilomyces fumosoroseus

The fruiting body of Paecilomyces fumosoroseus was collected at Mt. Mani, Ganghwa Island, Korea in September, 2001. This study was carried out to obtain the basic informations for the mycelial growth and fruiting body production of P. fumosoroseus in artificial media. The optimal conditions for the mycelial growth were obtained at 25°C and in the range of pH 6~9, respectively. P. fumosoroseus showed the favorable growth on Hamada medium. The carbon and nitrogen source favorable for mycelial growth were dextrin and histidine, respectively. Optimum C/N ratio suitable for optimal growth of P. fumosoroseus was observed on the culture media adjusted to the ratio of 40:1. The mycelial growth of P. fumosoroseus was optimal on corn meal agar supplemented with 30% of silkworm pupae. The most favorable fruiting body formation of P. fumosoroseus was obtained in the medium containing unpolished rice supplemented with 20% (w/w) silk worm pupae at 25°C under 100 lux.
