Does memorization without comprehension result in language learning

Muslims across the world memorize the Quran in Arabic for verbatim recall. Memorizers can be native speakers of Arabic, non-native speakers of Arabic, or non-Arabic speakers. The last category of speakers constitutes an unusual learner population, in that they cannot draw on primary linguistic knowledge to assist their memorization. Research on memorization suggests that memorization may instil sensitivity to patterns that can be used to bootstrap learning. The purpose of this study is to investigate if memorization of the Quran by non-Arabic speaking memorizers leads to pattern recognition in Classical Arabic. Memorizers of the Quran with no knowledge of Arabic were tested on their awareness of language patterns through a grammaticality judgement task (study 2). Contrary to implicit predictions in the research literature, findings from the language tests indicated that the participants had not developed any sensitivity to the morphological patterns of Classical Arabic. These results are discussed in the light of expert Quran memorizers’ reflections on their memorization practices (study 1), including what they brought to the act of memorization and what, according to them, underlay their success in memorization. It is proposed that memorizers’ extreme risk aversion in memorization stands in their way of developing awareness of the language patterns. This interpretation is further evidenced by results from a follow up study on native speakers of Arabic, who also did poorly on the grammaticality judgement task. The conclusion drawn is that Quran memorizers recite accurately because they don’t learn the language. It is further concluded that Quran memorization is a special case, in which a range of extra linguistic factors such as identity, motivation and intention play an important role
[Intra-nasal scanning of tumors in nasal cavity and paranasal sinus with endoscopic ultrasonography].

OBJECTIVE To evaluate endoscopic ultrasonography for masses in nasal cavity and paranasal sinus. METHODS Under the guidance of nasal endoscope, sonographic scan of 18 masses within nasal cavity and paranasal sinus was performed by using 10 MHz catheter transducer with diameter of 3.3 mm under local anesthesia. Twelve of them were benign tumors and 6 of them were malignant ones, which were confirmed by pathological examination of resected specimens. RESULTS Under the guidance of nasal endoscope, masses could be observed accurately with catheter transducer. On gray scale ultrasound, most masses were heterogeneous hypoechoic, tumors with rich blood vessels were lower hypoechoic, and some showed irregular anechoic area due to dilated vascular net. Neurofibroma was with well-defined and regular border and entire capsule; chordoma was without distinct edge and capsule. A giant pituitary tumor eroding bone of sphenoid sinus and intruding into nasal cavity. The relationship between mass and internal carotid artery could be demonstrated using color Doppler flow imaging (CDFI). Blood flowing signals in masses could be detected by CDFI, and spectral Doppler could discriminate arterial or venous blood flowing signals and measure its velocity. The rich blood supply was observed in fibroangioma, the rich flow signals and high velocity could be detected in malignant tumors. CONCLUSIONS Nasal endoscope-guided sonography for soft tissue masses in nasal cavity is of exact location, clear image and high resolution, which can reveal blood flow signals sensitively, differentiate arterial and venous blood signals and measure the velocity of them. It provides a new imaging modality for masses within nasal cavity, sinuses and skull base.
QMDP-Net: Deep Learning for Planning under Partial Observability

This paper introduces the QMDP-net, a neural network architecture for planning under partial observability. The QMDP-net combines the strengths of model-free learning and model-based planning. It is a recurrent policy network, but it represents a policy for a parameterized set of tasks by connecting a model with a planning algorithm that solves the model, thus embedding the solution structure of planning in a network learning architecture. The QMDP-net is fully differentiable and allows for end-to-end training. We train a QMDP-net on different tasks so that it can generalize to new ones in the parameterized task set and "transfer" to other similar tasks beyond the set. In preliminary experiments, QMDP-net showed strong performance on several robotic tasks in simulation. Interestingly, while QMDP-net encodes the QMDP algorithm, it sometimes outperforms the QMDP algorithm in the experiments, as a result of end-to-end learning.
Performance Measurement: Challenges for Tomorrow

This paper demonstrates that the context within which performance measurement is used is changing. The key questions posed are: Is performance measurement ready for the emerging context? What are the gaps in our knowledge? and Which lines of enquiry do we need to pursue? A literature synthesis conducted by a team of multidisciplinary researchers charts the evolution of the performance-measurement literature and identifies that the literature largely follows the emerging business and global trends. The ensuing discussion introduces the currently emerging and predicted future trends and explores how current knowledge on performance measurement may deal with the emerging context. This results in identification of specific challenges for performance measurement within a holistic systems-based framework. The principle limitation of the paper is that it covers a broad literature base without in-depth analysis of a particular aspect of performance measurement. However, this weakness is also the strength of the paper. What is perhaps most significant is that there is a need for rethinking how we research the field of performance measurement by taking a holistic systems-based approach, recognizing the integrated and concurrent nature of challenges that the practitioners, and consequently the field, face.
Metagenomic Analyses of an Uncultured Viral Community from Human Feces

ABSTRACT Here we present the first metagenomic analyses of an uncultured viral community from human feces, using partial shotgun sequencing. Most of the sequences were unrelated to anything previously reported. The recognizable viruses were mostly siphophages, and the community contained an estimated 1,200 viral genotypes.
Phosphorus Supplementation Mitigated Food Intake and Growth of Rats Fed a Low-Protein Diet

Abstract Background: Low protein intake is associated with various negative health outcomes at any life stage. When diets do not contain sufficient protein, phosphorus availability is compromised because proteins are the major sources of phosphorus. However, whether mineral phosphorus supplementation mitigates this problem is unknown, to our knowledge. Objective: Our goal was to determine the impact of dietary phosphorus supplementation on food intake, weight gain, energy efficiency, body composition, blood metabolites, and liver histology in rats fed a low-protein diet for 9 wk. Methods: Forty-nine 6-wk-old male Sprague-Dawley rats were randomly allocated to 5 groups and consumed 5 isocaloric diets ad libitum that varied only in protein (egg white) and phosphorus concentrations for 9 wk. The control group received a 20% protein diet with 0.3% P (NP-0.3P). The 4 other groups were fed a low-protein (10%) diet with a phosphorus concentration of 0.015%, 0.056%, 0.1%, or 0.3% (LP-0.3P). The rats' weight, body and liver composition, and plasma biomarkers were then assessed. Results: The addition of phosphorus to the low-protein diet significantly increased food intake, weight gain, and energy efficiency, which were similar among the groups that received 0.3% P (LP-0.3P and NP-0.3P) regardless of dietary protein content. In addition, phosphorus supplementation of low-protein diets reduced plasma urea nitrogen and increased total body protein content (defatted). Changes in food intake and efficiency, body weight and composition, and plasma urea concentration were highly pronounced at a dietary phosphorus content <0.1%, which may represent a critical threshold. Conclusions: The addition of phosphorus to low-protein diets improved growth measures in rats, mainly as a result of enhanced energy efficiency. A dietary phosphorus concentration of 0.3% mitigated detrimental effects of low-protein diets on growth parameters.
Cheetahs, Acinonyx jubatus, balance turn capacity with pace when chasing prey

Predator–prey interactions are fundamental in the evolution and structure of ecological communities. Our understanding, however, of the strategies used in pursuit and evasion remains limited. Here, we report on the hunting dynamics of the world's fastest land animal, the cheetah, Acinonyx jubatus. Using miniaturized data loggers, we recorded fine-scale movement, speed and acceleration of free-ranging cheetahs to measure how hunting dynamics relate to chasing different sized prey. Cheetahs attained hunting speeds of up to 18.94 m s−1 and accelerated up to 7.5 m s−2 with greatest angular velocities achieved during the terminal phase of the hunt. The interplay between forward and lateral acceleration during chases showed that the total forces involved in speed changes and turning were approximately constant over time but varied with prey type. Thus, rather than a simple maximum speed chase, cheetahs first accelerate to decrease the distance to their prey, before reducing speed 5–8 s from the end of the hunt, so as to facilitate rapid turns to match prey escape tactics, varying the precise strategy according to prey species. Predator and prey thus pit a fine balance of speed against manoeuvring capability in a race for survival.
Dental implant surgery in patients in treatment by dabigatran

OBJECTIVES The aim of this study was to evaluate the incidence of bleeding complications after dental implant placement in patients in treatment by the oral anticoagulant dabigatran following a specific protocol. MATERIAL AND METHODS Seventy-one patients were divided into two groups: 29 had been taking dabigatran for over 6 months (150 mg orally every 12 h) before implant surgery (dabigatran group) and a control group consisting of 42 healthy subjects. Patients were treated in an outpatient setting. All subjects received dental implants in different positions, dabigatran group patients 12 h after the last dose of dabigatran. Nonabsorbable sutures were used and patients were given gauzes impregnated with tranexamic acid 5% to bite on for 30-60 min. Dabigatran patients resumed medication 8 h after the procedure, resuming usual dosage (every 12 h) the day after surgery. RESULTS Two dabigatran patients and two control patients presented slight bleeding the day after surgery. Bleeding was managed with gauzes impregnated with tranexamic acid. No statistically significant differences (P = 0.542) were found in relation to bleeding episodes between the groups, with a relative risk of 0.675 based on the pooled groups and a 95% confidence interval of 0.090-5.088. CONCLUSIONS Dental implant surgery in patients taking dabigatran can be performed safely providing 12 h have passed since the last dose and local hemostatic measures are applied. Normal dosage can be resumed 8 h after implant surgery.
'An Unbelievable Academic and Personal Experience': Issues around teaching undergraduate field courses in Africa

This paper explores the teaching of geography field courses in Africa for UK university undergraduates. Using largely qualitative feedback, the experiences of students, staff and local communities involved in field courses to Kenya, Zimbabwe and The Gambia are evaluated. Benefits and disbenefits of these field courses to the participating students, the local community and teaching staff are scrutinised. The paper concludes that such field courses to 'exotic' destinations are an effective means to student recruitment and certainly achieve their aims while providing meaningful teaching and learning experiences. Furthermore, the analysis shows that field courses to 'poor' destinations in sub-Saharan Africa can avoid dangers of 'development tourism' if conducted with ethical sensitivity.

This paper attempts to review and understand the applications of IoT in personalised healthcare to achieve excellent healthcare at affordable costs. We have explained in brief how IoT functions and how it is used in conjunction with wireless and sensing techniques to implement the desired healthcare applications. Keywords— Internet of things, personalised healthcare, Ubiquitous computing, wireless sensor networks.
Examining Normative Influence in Persuasive Health Messages: The Moderating Role of Identification With Other Parents

This study tests the interaction between an individual-level characteristic—identification with other parents—and the effects of persuasive messages about nutrition. In an online experiment conducted in 2010, 242 parents of children aged five through nine were randomized to a message condition. The parents were exposed to a message that emphasized normative justifications or personal benefit justifications for feeding one’s child healthy foods (or no message). Parents who identified with other parents were more influenced by normatively focused messages than were parents with lower levels of identification. Theoretical and practical implications for message design are presented.

Where gifted children do and do not excel on metacognitive tasks

Metacognition is an important component of advanced intellectual performance and, therefore, has been proposed to be more advanced in intellectually gifted than average children. However, existing research comparing gifted to average children's metacognitive abilities does not support this idea uniformly. Compared to average children, gifted children appear to have generally better declarative metacognitive knowledge and better ability to transfer strategies to situations distinct from those in which the strategy was learned. However, gifted children do not demonstrate consistently better strategy use, maintenance, or near transfer compared to average children. Nor do they display better cognitive monitoring ability compared to average children. Metacognition appears to be important to the development of high achievement in a domain. We argue that metacognitive abilities might be incorporated as additional criteria for entry into programs for the gifted beyond standard intelligence measures. Several ident.
Factors Influencing Customer Loyalty Toward Online Shopping

The significant growth of online shopping makes the competition in this industry become more intense. Maintaining customer loyalty has been recognized as one of the essential factor for business survival and growth. The purpose of this study is to examine empirically the influence of satisfaction, trust and commitment on customer loyalty in online shopping. This paper describes a theoretical model for investigating the influence of satisfaction, trust and commitment on customer loyalty toward online shopping. Based on the theoretical model, hypotheses were formulated. The primary data were collected from the respondents which consists of 300 students. Multiple regression and qualitative analysis were used to test the study hypotheses. The empirical study results revealed that satisfaction, trust and commitment have significant impact on student loyalty toward online shopping.
Molecular Neuroimaging in Posttraumatic Stress Disorder

Over the past decade, an increasing number of neuroimaging studies have provided insight into the neurobiological mechanisms of posttraumatic stress disorder (PSTD). In particular, molecular neuroimaging techniques have been employed in examining metabolic and neurochemical processes in PTSD. This article reviews molecular neuroimaging studies in PTSD and focuses on findings using three imaging modalities including positron emission tomography (PET), single photon emission computed tomography (SPECT), and magnetic resonance spectroscopy (MRS). Although there were some inconsistences in the findings, patients with PTSD showed altered cerebral metabolism and perfusion, receptor bindings, and metabolite profiles in the limbic regions, medial prefrontal cortex, and temporal cortex. Studies that have investigated brain correlates of treatment response are also reviewed. Lastly, the limitations of the molecular neuroimaging studies and potential future research directions are discussed.
Scriptedness and Televised Sports: Violent Consumption and Viewer Enjoyment

Extending Raney and Depalma’s research, this study examined effects of sport production on sport consumption. An experimental design crossed scripted (vs. unscripted) sport with violence (vs. nonviolence) to investigate the effects of both variables on violent outcomes and enjoyment. After viewing one of four clips, participants responded to three incomplete story stems, and responses were coded to measure hostile expectancy bias as a form of violent outcome. Participants also responded to their enjoyment of the clip they consumed. Analyses showed a main effect that consuming sport violence increased participants’ hostile expectancy bias. However, a significant interaction showed that scriptedness moderated this effect, such that violence increased hostile expectancy bias only in the scripted condition. Enjoyment was also affected by scriptedness and violence, as violent nonscripted sports were enjoyed more than all other conditions. Results suggest that violence in sports may be interpreted differently based on the scriptedness of the sport and may be processed differently than violence in other forms of entertainment. Implications of these findings are discussed, as are limitations and future directions for study.

Momentum Equity Strategies: Are Certain Firm-Specific Variables Crucial in Achieving Superior Performance in Short Term Holding Periods?

In this study we analyze the performance of variable-oriented momentum strategies, in order to detect alternatives which offer higher returns, compared to the simple price momentum strategies, for no significantly extra risk, in the very short run. Portfolios are constructed using twenty firm specific variables, of U.S. stocks traded in NYSE, NASDAQ and AMEX for a full six year period starting on March of 2002. We calculate a volatilityreward (VR) ratio for each observation, treated as a performance measure, and we apply Principal Component Analysis (PCA) on their series in order to detect the variables which contribute mostly in enhancing the performance of simple momentum strategies. Our findings suggest that short term investors could significantly benefit from momentum strategies if they take into account past firm specific information, which indirectly indicates a market underreaction to various announcements related to firms’ EPS. In particular, top analysts’ EPS estimate revisions followed by low P/E and high ROE contribute the most in producing momentum portfolios of superior performance, compared to a simple price
Llull and Copeland Voting Broadly Resist Bribery and Control

Control of elections refers to attempts by an agent to, via such actions as addition/deletion/partition of candidates or voters, ensure that a given candidate wins (Bartholdi, Tovey, & Trick 1992). An election system in which such an agent's computational task is NP-hard is said to be resistant to the given type of control. Aside from election systems with an NP-hard winner problem, the only systems known to be resistant to all the standard control types are highly artificial election systems created by hybridization (Hemaspaandra, Hemaspaandra, & Rothe 2007b). In this paper, we prove that an election system developed by the 13th century mystic Ramon Llull and the well-studied Copeland election system are both resistant to all the standard types of (constructive) electoral control other than one variant of addition of candidates. This is the most comprehensive resistance to control yet achieved by any natural election system whose winner problem is in P. In addition, we show that Llull and Copeland voting are very broadly resistant to bribery attacks, and we integrate the potential irrationality of voter preferences into many of our results.
Congenital muscular dystrophy syndromes distinguished by alkaline and acid phosphatase, merosin, and dystrophin staining

Congenital muscular dystrophy syndromes are characterized by congenital weakness, contractures, and dystrophic features on muscle biopsy. However, these syndromes are often difficult to diagnose precisely because their clinical and pathologic characteristics are not specific and resemble changes in other myopathies. We examined muscle biopsies from 20 children with a congenital muscular dystrophy syndrome. Disease controls with dystrophies or other myopathies (n=19) and normal individuals (n=15) were studied for comparison. In each biopsy we determined (1) numbers of muscle fibers with alkaline phosphatase (AlkP) staining, (2) numbers of acid phosphatase-(AcP) positive cells, (3) dystrophin levels by immunocytochemistry, and (4) the distribution of merosin and laminin-A staining. A ratio of AcP:AlkP staining was calculated for each biopsy. In nine patients with congenital muscular dystrophy (younger than 4 years of age) with normal dystrophin, the AcP:AlkP ratio was low (0.09 +/- 0.03). In contrast, in Duchenne muscular dystrophy, the AcP:AlkP ratio was 15 times higher (1.6 +/- 0.04, p=0.001). The three children with congetial muscular dystrophy syndromes and reduced dystrophin and one child with facioscapulohumeral dystrophy had AcP:AlkP ratios in the range of Duchenne muscular dystrophy patients (2.4 +/- 1.4). Low Ac:AlkP ratios were related to relative absence of AcP-positive cells. Merosin staining was absent in 5 of the 17 congenital muscular dystrophy biopsies tested. None of the 5 children with merosin-negative but all 12 with merosin-positive stains walked (p=0.0002). We conclude that a pattern of few AcP-positive cells in the setting of numerous AlkP staining muscle fibers has specificity for congenital muscular dystrophy syndromes and provides histopathologic support for the diagnosis. Reduced merosin in muscle predicts more severe weakness and long-term disability.
