Opposing effects of impulsivity and mindset on sources of science self-efficacy and STEM interest in adolescents

Impulsivity has been linked to academic performance in the context of Attention Deficit Hyperactivity Disorder, though its influence on a wider spectrum of students remains largely unexplored, particularly in the context of STEM learning (i.e. science, technology, engineering, and math). STEM learning was hypothesized to be more challenging for impulsive students, since it requires the practice and repetition of tasks as well as concerted attention to task performance. Impulsivity was assessed in a cross-sectional sample of 2,476 students in grades 6–12. Results show impulsivity affects a larger population of students, not limited to students with learning disabilities. Impulsivity was associated with lower sources of self-efficacy for science (SSSE), interest in most STEM domains (particularly math), and self-reported STEM skills. The large negative effect size observed for impulsivity was opposed by higher mindset, which describes a student’s belief in the importance of effort when learning is difficult. Mindset had a large positive effect size associated with greater SSSE, STEM interest, and STEM skills. When modeled together, results offer that mindset interventions may benefit impulsive students who struggle with STEM. Together, these data suggest important interconnected roles for impulsivity and mindset that can influence secondary students’ STEM trajectories.
Statistical significance in empirical software engineering research: A maturity model

Software engineering research is maturing and papers increasingly support their arguments with empirical data from a multitude of sources, using statistical tests to judge if and to what degree empirical evidence supports their hypotheses. The objective of this paper was to develop a statistical maturity model. First, we manually reviewed papers from five well-known and top-ranked journals producing a review protocol along with the view of current (2015) state of art concerning statistical maturity, practical significance and reproducibility of empirical software engineering research. Our protocol was then used as ground truth, i.e., training set, for a semi-automatic classification of studies for the years 2001--2015 using close to 4,900 papers. We used the extracted data to develop a statistical maturity model. The statistical maturity of empirical software engineering research has an upward trend in certain areas (e.g., use of nonparametric statistics, but also more generally in the usage of quantitative analysis). However, we also see how our research area currently often fails to connect statistical analysis to practical significance. We believe that the statistical maturity model can be used by researchers and practitioners to build a coherent statistical analysis and guide them in the choice of statistical approaches of its steps.
Immune Heterogeneity Between Primary Tumors and Corresponding Metastatic Lesions and Response to Platinum Therapy in Primary Ovarian Cancer

CD3+ and CD8+ lymphocytes are well known prognostic markers in primary ovarian cancer. In contrast, the predictive value of the immune infiltrate concerning treatment response and the involvement of immune heterogeneity between primary and metastatic lesions are poorly understood. In this study, the immune infiltrate of 49 primary tumors and 38 corresponding lesions in the omentum (n = 23) and the peritoneum (n = 15) was immunohistochemically analyzed and correlated with clinicopathological factors and platinum-sensitivity. Immune heterogeneity was observed between paired primary and metastatic lesions for all immune cell phenotypes. The stromal immune infiltrate was higher in the omental lesions than in the primary tumors, which was reflected by CD45 (p = 0.007), CD3 (p = 0.005), CD8 (p = 0.012), and PD-1 (programmed cell-death protein 1) (p = 0.013). A higher stromal infiltrate of both CD45+ and CD3+ cells in the omental lesions was associated with the detection of lymph node metastasis (CD45, p = 0.018; CD3, p = 0.037). Platinum-sensitive ovarian cancers revealed a higher intratumoral CD8+ infiltrate in the peritoneal lesions compared to the primary tumors (p = 0.045). In contrast, higher counts of stromal PD-1+ cells in the peritoneal lesions have been associated with reduced platinum-sensitivity (p = 0.045). Immune heterogeneity was associated with platinum response and might represent a selection marker for personalized therapy.
taxonomic diversity of aquatic insect assemblages and unctional feeding groups in neotropical savanna headwater streams

Biological diversity can be divided into: alpha ( , local), beta ( , difference in assemblage composition among locals), and gamma ( , total diversity). We assessed the partitioning of taxonomic diversity of Ephemeroptera, Plecoptera and Trichoptera (EPT) and of functional feeding groups (FFG) in neotropical savanna (southeastern Brazilian cerrado) streams. To do so, we considered three diversity components: stream site ( ), among stream sites ( 1), and among hydrologic units ( 2). We also evaluated the association of EPT genera composition with heterogeneity in land use, instream physical habitat structure, and instream water quality variables. The percentage of EPT taxonomic diversity (20.7%) was smaller unctional feeding groups razilian cerrado than the 1 and 2 diversity percentages (53.1% and 26.2%, respectively). The percentage of EPT FFG collector-gatherer diversity (26.5%) was smaller than that of 1 diversity (55.8%) and higher than the 2 (17.7%) diversity. The collector-gatherer FFG was predominant and had the greatest diversity percentage among stream sites ( 1, 55.8%). Our findings support the need for implementing regional scale conservation strategies in the cerrado biome, which has been degraded by anthropogenic activities. © 2016 Elsevier Ltd.

Suppress α

It is proposed that UG allows the rule "suppress a" to be associated with certain morphological operations. As a morpholexical rule, it can only apply to θ roles directly assigned by the verb; we assume that the relevant notion of "direct" θ marking includes θ marking of the subject by the VP. With a set to external θ role, "suppress a" representspassivization in the theory of Chomsky (1981), Marantz (1984), and others. Setting a to internal θ role results in antipassivization. In order to explain the restriction of antipassivization (the suppression of the internal argument of a transitive verb) to ergative languages, a theory ofergativity is proposed. This approach to ergativity leads to a parameterized version of Burzio's generalization, which is the moving force behind the suppression of accusative Case in passives. We derive from our revision of Burzio's generalization the prediction that antipassivization is only possible in ergative languages, as well as the somewhat surprising but apparently correct prediction that there are languages that exclude passivization. The lexicalist approach to passivization is explanatory and more typologically sound than the "incorporation" analysis. It is also more in keeping with the function of the passive, and the interaction of passivization with derivational processes. It is the thesis of this study that universal grammar (UG) allows the rule specified in (1) to be associated with certain morphological operations.
Arrowroot ( Maranta Arundinacea ) : Starch Extraction , Processing , and By-Products Utilization

Abstract—The storage roots called rhizomes of Arrowroot (Maranta Arundinacea) vary in size and number depending upon the soil, climate and age of the plant. Rhizomes are the main source of starch that are easily digested when extracted and produces a dry white powder. This powder is a source of one of the purest form of natural carbohydrates which is considered gluten free and superior quality starch used in making the first class biscuits, pastries, pudding, cakes, native Filipino delicacies and many more. In Marinduque, Philippines arrowroot cookies are one of the most popular “pasalubong” or food products produced from arrowroot starch. For every one kilo of arrowroot rhizomes, starch recovery commonly ranges from 10-20% depending on its quality. This study resulted only to 13% or 390 grams dried starch recovery using 3 kilograms of fresh rhizomes, while water produced amounted to 59% and remaining 28% went to waste rhizomes or “sapal”. Waste from water can be developed into wine while grinded rhizomes or “sapal” into flour, handmade paper, and novelty items. Proximate analysis shows that waste rhizomes flour contains 11.39% moisture, 2.71% ash, 1.27% crude protein, 0.05% crude fat, 6.12% crude fiber, and 78.46% nitrogen-free extract. Nutrition fact per serving size of 100 grams shows 320 calories, 0 fat, 78 grams carbohydrates, 6 grams dietary fiber and 1 gram protein. Two arrowroot wine samples were also tested which resulted to alcohol content of 7% and 9% respectively while physical testing of handmade paper from “sapal” shows poor quality. To increase starch recovery, further research and studies should be done focusing on pre and postharvest activities and facilities on how to minimize losses and maximize volume of starch recovery. Conversely, potential to utilize waste water into bioethanol and biogas may also be considered. Arrowroot waste flour can be developed into human and animal feed substitutes and additives as food ingredients while the arrowroot waste fiber into textile and construction materials. Considering the foregoing, the utilization of arrowroot starch by-products foresees positive impacts and adds value for arrowroot that may lead to increased price and productivity.
Sentiment Analysis- Strategy for Text Pre-Processing

It “is taxing to understand the current trends in the online market and then abridge the general opinions about the products due to the existence of diversified social media data. This has created a need for real time opinion mining which is analysis of the sentiments that classifies the text into positive and negative emotion polarities. In this paper, the author explores the most important step in sentiment analysis that is data pre-processing and analyses the different techniques used for pre-processing in R. The results show that using library packages provides better results with respect to the method where direct functions are used
Accurate high-throughput screening based on digital protein synthesis in a massively parallel femtoliter droplet array

A strategy based on Poisson statistics enables a rapid and efficient acquisition of enzyme mutants from just a few clones. We report a general strategy based on digital counting principle that enables an efficient acquisition of enzyme mutants with desired activities from just a few clones within a day. We prepared a high-density femtoliter droplet array, consisting of 1 million uniform droplets per 1 cm2 to carry out high-throughput protein synthesis and screening. Single DNA molecules were randomly distributed into each droplet following a Poisson process to initiate the protein synthesis with coupled cell-free transcription and translation reactions and then recovered by a microcapillary. The protein yield in each droplet was proportional to the number of DNA molecules, meaning that droplets with apparent intensities higher than the Poisson distribution–predicted maximum can be readily identified as the exact hits exhibiting the desired increased activity. We improved the activity of an alkaline phosphatase up to near 20-fold by using less than 10 nl of reagents.
Periodized Aerobic Interval Training Modifies Geometric Indices of Heart Rate Variability in Metabolic Syndrome

Background: Metabolic syndrome (MetS) influences the autonomic modulation, increasing the risk of cardiovascular events, which demands the identification of effective treatments for this population. Considering this, the study has the objective of evaluating the effects of periodized aerobic interval training (AIT) on geometrical methods of heart rate variability (HRV) on individuals with MetS. Methods: 52 individuals with MetS were considered for analysis. They were divided into two groups: aerobic interval training group (AITG; n = 26) and control group (CG; n = 26). The AITG performed 16 weeks of periodized AIT. For HRV analysis, the heart rate was recorded beat-by-beat at the beginning and the end of the AIT program and geometrical methods were used for analysis. Results: significant increase was observed for triangular index (RRtri, −1.25 ± 0.58 vs. 1.41 ± 0.57), standard deviation of distances from diagonal to points (SD1, −0.13 ± 1.52 vs. 4.34 ± 1.49), and standard deviation of distances from points to lines (SD2, −2.14 ± 3.59 vs. 11.23 ± 3.52) on AITG compared to CG. Significant differences were not observed for triangular interpolation of normal heartbeats interval histogram (TINN, −4.05 ± 17.38 vs. 25.52 ± 17.03) and SD1/SD2 ratio (0.03 ± 0.02 vs. 0.00 ± 0.02). Qualitative analysis of the Poincaré plot identified increase on dispersion of both short and long-term intervals between successive heartbeats (RR interval) on AITG after the AIT program. Conclusion: geometric indices of HRV suggest an increase in cardiac autonomic modulation in individuals with MetS after 16 weeks of periodized AIT.
A permutation test based on the restricted mean survival time for comparison of net survival distributions in non-proportional excess hazard settings

Net survival is used in epidemiological studies to assess excess mortality due to a given disease when causes of death are unreliable. By correcting for the general population mortality, it allows comparisons between regions or periods and thus evaluation of health policies. The Pohar-Perme non-parametric estimator of net survival has been recently proposed, soon followed by an appropriate log-rank-type test. However, log-rank tests are known to be under-optimal in non-proportional settings (e.g. crossing of the hazard functions). In classical survival analysis, one solution is to compare the restricted mean survival times. A difference in restricted mean survival time represents a life benefit or loss over the studied period. In the present article the restricted mean net survival time was used to derive a specific test statistic to compare net survivals in proportional and non-proportional hazards settings. The new test was generalized to more than two groups and to stratified analysis. The test performance was assessed on simulation study, compared to the log-rank-type test, and its use illustrated on a population-based colorectal cancer registry. The new test for net survival comparisons proved robust to non-proportionality and well-performing in proportional hazards situations. Furthermore, it is also suited to the classical survival framework.

Meta-Semantic Representation for Early Detection of Alzheimer’s Disease

This paper presents a new task-oriented meaning representation called meta-semantics, that is designed to detect patients with early symptoms of Alzheimer’s disease by analyzing their language beyond a syntactic or semantic level. Meta-semantic representation consists of three parts, entities, predicate argument structures, and discourse attributes, that derive rich knowledge graphs. For this study, 50 controls and 50 patients with mild cognitive impairment (MCI) are selected, and meta-semantic representation is annotated on their speeches transcribed in text. Inter-annotator agreement scores of 88%, 82%, and 89% are achieved for the three types of annotation, respectively. Five analyses are made using this annotation, depicting clear distinctions between the control and MCI groups. Finally, a neural model is trained on features extracted from those analyses to classify MCI patients from normal controls, showing a high accuracy of 82% that is very promising.
Efficient Multimedia Contents Management System with Tag Recommendations

— Recently, rapid development of internet technology, the amount of data on the web is exponentially generated. Because of that, users are difficult to find desired multimedia data. For efficient search and management of multimedia data, collaborative tagging is appropriated to describe and categorize the data. Then we proposed the collaborative multimedia management systems based on tag recommendation. Our system suggests the tag candidates for describing and categorizing the multimedia contents.
SAP HANA goes private - From Privacy Research to Privacy Aware Enterprise Analytics

Over the last 20 years, the progress of information technology has allowed many companies to generate, integrate, store, and analyze data of unprecedented size and complexity. In many cases, this data is personal data and how it can be used is therefore subject to laws that depend on the spe-ciﬁc countries and application domains. For example, the General Data Protection Regulation (GDPR) introduced in the European Union imposes strict rules on how personal data can be processed. Analyzing personal data can create tremendous value, but at the same time companies must ensure that they remain legally compliant. Unfortunately, existing systems oﬀer only limited or no support at all for processing personal data in a privacy-aware manner. Approaches that have emerged from the academic and industrial research environments need to be integrated into large systems (like enterprise systems) in a manageable and scalable way. In many IT environments, it is also desirable and necessary to combine and to integrate personal data with other (non-personal) data in a seamless fashion. Inthis paper, we present the ﬁrst steps that SAP has taken to provide its database management system SAP HANA with privacy-enhanced processing capabilities, referred to in the following as SAP HANA Data Anonymiza-tion. Various goals on both the conceptual and technical levels were followed with the aim of providing SAP customers today with an integrated processing environment for personal and non-personal data.
Simulation and Experimental Results for the Closed Loop Controlled DC to DC Forward Converter

A Closed loop controlled DC to DC forward converter is a requisite for the server SMPS system. High efficiency, Isolation, Steady state voltage, Transient response, High switching frequency, reduced noises and range of steady state are all necessary requirements for the forward converter. In this paper, a 40 V forward converter for charging the battery of server SMPS is proposed. The proposed converter consists of a NPC-ARS circuit for soft switching on the primary side and an isolation transformer and a rectifier structure on the secondary side. With this modified NPC-ARS circuit topology, soft switching occurs during conversion and reduces the switching loss in this system. This paper proposed the simulation of closed loop controlled circuit, for the forward converter with RCD snubber, double forward converter and the Modified forward converter are analyzed and discussed in this paper. From comparison of performance in the closed loop model, a suitable converter is proposed for the sever SMPS system. The proposed circuit achieves steady state voltage, when the disturbance occurs. A 40 V proposed circuit is designed as experimental model to verify and compare the simulation and experimental results. This paper proposed the simulation and experimental results of the forward converter.
EFFECTS OF GRAFTING COMBINATIONS ON THE FRUIT QUALITY FOR THE PINOVA APPLE TREE

The quality of apple fruits is influenced by variety and within each variety by the rootstock and by the culture technology applied. The research presented in this paper highlighted the influence of the rootstock on the fruit quality. The experiment was conducted during 2016-2017 in the Vâlcea plant nursery, in Romania, as a comparative study for the ʻPinovaʼ variety with several rootstocks (M9, B9, M20, Pi80, M106), including variants with grafting interstems (B9/A2, B9/M111). The size of the fruit was larger for the trees grafted on the rootstock B9 with the interstem M111, while the firmness was positively influenced by the rootstocks M9 and B9/A2. The content of soluble dry substance was favourably influenced by the rootstocks M20, B9 and Pi 80, while the titratable acidity had higher values for the fruits produced by the trees grafted on M106 and M9/M111. The total anthocyanins content was higher for the fruits obtained from the trees grafted on the rootstock B9 with the interstems M111 and A2.
Comparative Isolation Techniques of 1 x 2 MIMO Antenna for 5 G 1 ,

In this paper a simple mender line EBG with slotted ground planer 1x2 rectangle patch multiband antenna is designed and simulated. Presently the communication system provides the ultra wideband internet services. This is possible due to higher data rates and improved spectral efficiency of the communication system. The higher data rates and improved spectral efficiency are achieved by the use of MIMO antenna. MIMO antenna provide a significant increase in data rate and range of link without more bandwidth and power. The main design challenge in MIMO antenna is to attain high isolation between the antenna elements. This paper reviews various decoupling techniques to improve the mutual coupling between the antenna elements.
