Examining the impact of stemming on clustering Turkish texts

Preprocessing is an important step in information retrieval and text mining. In this study, we examined the impact of stemming on clustering Turkish texts. We used two datasets compiled from web sites of Turkish news agencies, and performed extensive experiments. We empirically show that there is no significant evidence that stemming always improves the quality of clustering for texts in Turkish. However, when stemming is used, dimensionality of the document-term matrix dramatically decreases without inversely affecting the clustering performance. As a result, it is highly recommended to apply stemming for clustering Turkish texts.
The Case for Including Informant Reports in the Assessment of Adulthood ADHD

Attention-deficit/hyperactivity disorder (ADHD) is now known to continue into adulthood for many children diagnosed with ADHD. Estimates of persistence reach up to 75% (Biederman, Petty, Clarke, Lomedico, & Faraone, 2011) in some studies. For example, in the Milwaukee longitudinal study of hyperactive children to age 27, 56% had symptoms of ADHD that were two standard deviations above the control group mean (Barkley, Murphy, & Fischer, 2008). Four or more symptoms of ADHD were experienced by 58% of the young adults with childhood ADHD who were followed by Biederman and colleagues (Biederman, Monuteaux, Mick, Spencer et al., 2006). Similarly, Weiss and Hechtman (1993) found clinically elevated ADHD symptoms in 66% of young adults diagnosed with ADHD in childhood. Impairment from ADHD reaches into adult-relevant domains of functioning that cut across educational (Mannuzza, Klein, Bessler, Malloy, & Hynes, 1997), vocational (Kuriyan et al., 2013), social (Friedman et al., 2003), legal (Mannuzza, Klein, & Moulton, 2008), and health-related (Flory, Molina, Pelham, Gnagy, & Smith, 2006) domains of life. These estimates of persistence roughly comport with the prevalence rate of 4.4% for adult ADHD reported by Kessler and colleagues (2006) from the National Comorbidity Survey (Kessler & Merikangas, 2004). We expect that this figure for adults may rise due to several converging trends. First, the results of a national survey recently revealed that 11% of children and adolescents in the United States receive a diagnosis of ADHD at some time in their lives (Visser et al., 2014). Although only 6.1% are being treated at any one point in time, these figures represent a 42% increase in rates of diagnosis in the last eight years (Visser et al., 2014). Prescriptions for the most common pharmacologic treatment of ADHD, central nervous system stimulants, have increased 25% for adolescents and 53% for adults in the past four years (Express Scripts, 2014; Visser et al., 2014). Finally, the continuing rise in abuse and diversion of stimulant prescriptions that has been occurring across college campuses in recent years (McCabe, West, Teter, & Boyd, 2014) and widespread Internet-based tips for “faking ADHD” (http://exiledonline. com/adderall-tips-how-to-convinceyour-shrink-you-have-addadhd) suggest that growing numbers of adults with ADHD may be attempting to procure prescriptions without legitimate medical need. Taken together, these statistics clearly point to an increasing
Empatía y conducta prosocial durante la adolescencia

Resumen Aunque la relación entre empatía y prosocialidad viene siendo estudiada desde hace años prevalece aún una importante indefinición conceptual e incluso de resultados. Este trabajo pretende aportar algo de luz a la relación entre ambos conceptos y otras variables del contexto social en una muestra de adolescentes. Un total de 513 adolescentes, 221 chicos y 292 chicas de edades comprendidas entre los 13 y los 19 años cumplimentaron un cuestionario que incluía medidas sobre empatía, conducta prosocial, y aspectos relacionados con las variables familiares y de relación con los iguales. Entre los resultados obtenidos podemos destacar la relación existente entre conducta prosocial y empatía disposicional, y entre estas dos variables y las relaciones con la familia y con el grupo de los iguales. Así mismo, y en concordancia con abundante literatura científica, hallamos mayores niveles de prosocialidad y empatía en las chicas que en los chicos.
A modified-hopped single delay approach for UWB TR receiver using the modified Hadamard matrix

The Transmitted-Reference (TR) is a technique used to improve the performance (gain) of received noisy multipath component in indoor and outdoor UWB signal. This technique is utilized by ultra-wide band (UWB) transceiver which receives very short transmitted pulses (less than 1 ns) using popular modulation and spread spectrum of time hopping. It is well-known that the inter pulse interference (IPI) is one of the most important challenges in transmitted reference impulse radio (TR IR-UWB) receiver. In this paper, a Modified-Hopped Single Delay (MHSD) TR receiver was proposed to completely remove the IPI drawback in TR and thereby increasing data rate and reducing Symbol Error Rate (SER) for better performance. This achievement requires a new modified 2 2 -Hadamard matrix by using bi-orthogonal codes. The size of Hadamard matrix was then enlarged and tested. The results obtained in this study shows that a gain of about 2.7 dB has been achieved compared to conventional single delay (SD) TR receiver used in wireless techniques.
Loneliness and poor health within families

This study was designed to determine whether loneliness clusters in families and if so, whether loneliness is associated with poor health in family members. Participants in the study were 456 individuals from 169 different family units who completed measures of loneliness, self-reported general health, self-reported physical symptoms, and structural support from family and friends. Results indicated that family membership explained significant variance in loneliness. Loneliness was associated with lower self-reported general health and more self-reported physical symptoms. Loneliness and physical symptoms were significantly associated for parents and grandparents, but not for young adults and their siblings. Finally, available structural support from family and friends were both negatively associated with loneliness and this relationship was uniform among all types of family members.
Group Membership Influences More Social Identification Than Social Learning or Overimitation in Children.

Group membership is a strong driver of everyday life in humans, influencing similarity judgments, trust choices, and learning processes. However, its ontogenetic development remains to be understood. This study investigated how group membership, age, sex, and identification with a team influenced 39- to 60-month-old children (N = 94) in a series of similarity, trust, and learning tasks. Group membership had the most influence on similarity and trust tasks, strongly biasing choices toward in-groups. In contrast, prior experience and identification with the team were the most important factors in the learning tasks. Finally, overimitation occurred most when the children's team, but not the opposite, displayed meaningless actions. Future work must investigate how these cognitive abilities combine during development to facilitate cultural processes.
A set of homology models of pore loop domain of six eukaryotic voltage‐gated potassium channels Kv1.1‐Kv1.6

Homology models of the pore loop domain of six eukaryotic potassium channels, Kv1.1‐Kv1.6, were generated based on the crystallographic structure of KcsA. The results of amino acid sequence alignment indicate that these Kv channels are composed of two structurally and functionally independent domains: the N‐terminal ‘voltage sensor’ domain and the C‐terminal ‘pore loop’ domain. The homology models reveal that the pore loop domains of these Kv channels exhibit similar folds to those of KcsA. The structural features and specific packing of aromatic residues around the selectivity filter of these Kv channels are nearly identical to those of KcsA, whereas most of the structural variations occur in the turret as well as in the inner and outer helices. The distribution of polar and nonpolar side chains on the surfaces of the KcsA and Kv channels reveals that they exhibit a segregation of side chains common to most integral membrane proteins. As the hydrogen bond between Glu71 and Asp80 in KcsA plays an important role in stabilizing the channel, the substituted Val residue in the Kv family corresponding to Glu71 of KcsA stabilizes the channel by making hydrophobic contact with Tyr residue from the signature sequence of the selectivity filter. The homology models of these Kv channels provide particularly attractive subjects for further structure‐based studies. Proteins 2004. © 2004 Wiley‐Liss, Inc.
Coded CSI Reference Signals for 5G - Exploiting Sparsity of FDD Massive MIMO Radio Channels

Future 5G systems are expected to provide higher performance, partly unleashed by massive MIMO as well as tight cooperation like joint transmission CoMP. For paired and unpaired spectrum below 6 GHz RF-frequency bands, frequency division duplex as well as time division duplex (FDD/TDD) has to be supported. The use of large cooperation areas over several cells together with massive MIMO downlink transmission is challenging in particular for FDD systems, due to two requirements. First, the channel state information (CSI) for downlinks from a large number of antennas has to be obtained without unreasonable overhead due to the transmission of orthogonal downlink reference (pilot) signals from these antennas. Second, relevant channel estimates have to be made available at the network side without an unrealistic uplink control signaling overhead. Pilot contamination has been extensively discussed in the literature as upper bounding performance, due to either exploding overhead for orthogonal reference signals or due to limited CSI accuracy, which is detrimental especially for sensitive interference cancellation schemes. We here propose a strategy for channel estimation of a large number of FDD downlink channels that works without an unreasonable pilot overhead. Analysis of channel statistics for urban macro scenarios applying massive MIMO - potentially combined with strong UE beamforming - reveal a sparse nature of the typical channel matrices. We propose a coded allocation of CSI reference signals, inherently exploiting this sparse nature. It allows accurate CSI estimation of UE individual subsets of relevant channel components despite a very low reference signal overhead of typically less than 5 percent.
REVISITING SUPERVISED AGRICULTURAL EXPERIENCE

The professional and research literature in education show overwhelming supportfor experiential learning such as that typified by the Supervised Agricultural Experience (SAE) program. The agricultural education literature advocates SAE as an integral component of our total program. At the same time, some authors have suggested changes to SAE while others have questioned the appropriateness of some aspects of the program as it is currently conceptualized. The authors of this paper conducted a Delphi study using agricultural teacher educators, agricultural education teachers, state agricultural education supervisory staff members, and professional from the industry of agriculture to examine the efficacy of and structure of SAE as we move into the next century. They conclude that SAE remains a viable component of a comprehensive program of agricultural education but that its definition needs to be broadened and that its structure needs substantial expansion to accommodate the realities facing agricultural educators today.
A unified definition of clinical anthracycline resistance breast cancer

The purpose of the study was to determine the response rates (RR) and duration to second- and third-line chemotherapy programmes in patients with anthracycline-resistant breast cancer, utilizing various definitions of anthracycline resistance. This was a retrospective analysis performed on 1335 patients with metastatic breast cancer who participated in consecutive clinical trials of first line, anthracycline-containing combination chemotherapy (ACCC) at the University of Texas MD Anderson Cancer Center between July 1973 and April 1980. Anthracycline-resistant groups were identified using definitions of anthracycline resistance found in the literature: progressive disease as best response to ACCC (Group 1, n = 56 patients); progressive disease while receiving ACCC after an intervening response to the drug (Group 2, n = 84); progressive disease within 6 months of last dose of ACCC (Group 3, n = 233); and progressive disease within 12 months of last dose of ACCC (Group 4, n = 272). Second- and third-line therapies administered to these patients included methotrexate, doxorubicin, mitoxantrone, bisantrene, vinblastine, vindesine, melphalan, mitomycin, cisplatin, etoposide and others, but not taxanes. The distribution of patients' characteristics was similar between the four groups, as was the use of second- and third-line regimens. Response rate (RR) to second-line chemotherapy were 5% and 7.7% for Group 1 and Group 2 respectively. In contrast, RR to second-line chemotherapy were 21.6% and 15% for Group 3 and 4. The differences in response rate between the combination of Groups 1 and 2 and Groups 3 or 4 were significant (P = 0.005 and P = 0.04 respectively). These results indicate that strictly defined anthracycline resistance as defined in Groups 1 and 2 is associated with resistance to many other cytotoxic drugs. The definitions used in Groups 3 and 4 include many patients with responsive tumours, and a more favourable prognosis. © 2000 Cancer Research Campaign
Complexity in the therapeutic delivery of RNAi medicines: an analytical challenge

Introduction: Nucleic acids have witnessed a dramatic acceleration in their therapeutic exploitation and currently represent a growing number of applications in drug development pipelines. However, a more wide-spread development of therapeutics based on nucleic acids is restricted by their poor chemical and enzymatic stability in vivo, lack of cellular uptake and insufficient capability to reach intracellular targets. Areas covered: Advanced formulation of nucleic acids in nano-sized carriers may help unlocking their potential as therapeutic agents. Nano-sized matters own specific features responsible for inducing characteristic interactions with biological molecules and tissues. These properties enable for the enhancement of the nano-formulation’s therapeutic efficacy, but on the other hand, the nanomatters interactions in biological fluids are also responsible for adverse effects. The purpose of this review is to reflect on the complexity in the therapeutic delivery of RNA interference-based drugs emerging from the recent clinical experiences and report the actual technological and analytical advances introduced to solve it. Expert opinion: The complexity in the therapeutic delivery of nucleic acids and the heterogeneity of side effects make the interpretation of the therapeutic outcome difficult. Hence the development of analytical approaches applicable in the field of nucleic acid delivery is becoming a major challenge.

Competing Interpretations of Computer-Supported Cooperative Work in Organizational Contexts

This paper will investigate the competing discourses between empowerment and control that surrounded the use of Lotus Notes in the UK selling division of a pharmaceuticals company called Compound UK. We will suggest that managing and using Notes in Compound UK was itself a rhetorical accomplishment, and that, by focusing on rhetoric, we can illuminate some of the contradictions that surround the management and use of the technology. We will also show how the political and normative context is deeply implicated in the reproduction of these competing interpretations. Finally, we will suggest that the introduction of the discourse of empowerment is implicated in changes in the work practices in Compound UK, at least to a minimal degree.
Co-ordinate interleaved amplify-and-forward relaying with a multi-antenna relay

Amplify-and-forward (AF) relaying protocols are an important class of cooperative relaying protocols. Non-orthogonal AF (NAF) relaying, where the source sends new information while the relay forwards previously transmitted information, can achieve higher transmission rates than orthogonal relaying, where the source and relay do not transmit simultaneously. However, all the transmitted symbols in NAF relaying do not achieve full cooperative diversity. Precoding of symbols can address this problem. Recently, a coordinate interleaved NAF (CINAF) protocol has been proposed for NAF relaying with a single-antenna relay. In this paper, we extend this protocol to the multi-antenna relay (or multiple cooperative relays) setting. The linear transformation F used for amplifying at the relay is identified as an important component. Four designs for F are presented and compared extensively using simulations. The importance of channel state information (CSI) at the relay is studied. While full CSI about the source-relay channel is used, limited CSI about the relay-destination channel combined with antenna selection at the relay is observed to be sufficient to achieve most of the performance gain.
Workplace Violence Training Programs for Health Care Workers: An Analysis of Program Elements

Commercial workplace violence (WPV) prevention training programs differ in their approach to violence prevention and the content they present. This study reviews 12 such programs using criteria developed from training topics in the Occupational Safety and Health Administration’s (OSHA) Guidelines for Preventing Workplace Violence for Healthcare and Social Service Workers and a review of the WPV literature. None of the training programs addressed all the review criteria. The most significant gap in content was the lack of attention to facility-specific risk assessment and policies. To fill this gap, health care facilities should supplement purchased training programs with specific training in organizational policies and procedures, emergency action plans, communication, facility risk assessment, and employee post-incident debriefing and monitoring. Critical to success is a dedicated program manager who understands risk assessment, facility clinical operations, and program management and evaluation.
Transmission of Mouse Minute Virus (MMV) but Not Mouse Hepatitis Virus (MHV) Following Embryo Transfer with Experimentally Exposed In Vivo-Derived Embryos1

Abstract The present study investigated the presence and location of fluorescent microspheres having the size of mouse hepatitis virus (MHV) and of mouse minute virus (MMV) in the zona pellucida (ZP) of in vivo-produced murine embryos, the transmission of these viruses by embryos during embryo transfer, and the time of seroconversion of recipients and pups. To this end, fertilized oocytes and morulae were exposed to different concentrations of MMVp for 16 h, while 2-cell embryos and blastocysts were coincubated for 1 h. In addition, morulae were exposed to MHV-A59 for 16 h. One group of embryos was washed, and the remaining embryos remained unwashed before embryo transfer. Serological analyses were performed by means of ELISA to detect antibodies to MHV or MMV in recipients and in progeny on Days 14, 21, 28, 42, and 63 and on Days 42, 63, 84, 112, 133, and 154, respectively, after embryo transfer. Coincubation with a minimum of 105/ml of fluorescent microspheres showed that particles with a diameter of 20 nm but not 100 nm crossed the ZP of murine blastocysts. Washing generally led to a 10-fold to 100-fold reduction of MMVp. Washed MMV-exposed but not MHV-exposed embryos led to the production of antibodies independent of embryonic stage and time of virus exposure. Recipients receiving embryos exposed to a minimum of 107 mean tissue culture infective dose (TCID50)/ml of MHV-A59 and 102 TCID50/ml of MMVp seroconverted by Day 42 after embryo transfer. The results indicate that MMV but not MHV can be transmitted to recipients even after washing embryos 10 times before embryo transfer.
Identical Frames Based Video Steganography

Steganography is a technique employed for hiding the secret data under cover object. It resolves the problem of network security and provides secure communication through public and private channels. The cover can be text, image, audio or video. In this technique, the secret information is concealed in a video cover. Video file contains some identical frames, which are selected to hide the data. When steganography by this process is used, the probability to uncover the secret information by an attacker is very less as compared to the other methods to hide data frame-by-frame in a sequential manner. It also increases the robustness of data in case of frame dropping and frame adding attacks. In this proposed work a modified technique has been used to embed the data. This technique involves the application of wavelet transform on cover file followed by the application of LSB technique in sub bands. Lower frequency sub-band is selected to hide the encrypted data in cover file. The performance metrics such as Peak Signal to Noise Ratio (PSNR), Mean Square Error (MSE) and Mean Absolute Error (MAE), have been considered for experiment verification.
Study on Complex Event Processing for CPS: An Event Model Perspective

As an emerging technology approved in areas of database and business processing, CEP (Complex Event Process) faced challenges when applied in critical areas like CPS. Based on analysis such challenges from three aspects: event model definition, event semantic interoperability and event pattern matching, a semantic enhanced event model for CPS is proposed. While existing efforts have mainly focused on investigating a uniform CPS event representation with spatio-temporal attributes, our event model composed by two-layer structure, Basic Event Model (BEM) and Extended Information Set (EIS). A BEM could be extended with EIS by semantic adaptor for attribution semantic enhancement. In particular, we define the event process functions, like event attribution extraction and composition determination, for CPS action trigger exploit the CEP engine Esper. Examples show that such event model provides several advantages in terms of extensibility, flexibility and heterogeneous support, and lay the foundations of event-based system design in CPS.
