Addressing the Problem of Student- Athlete Sleepiness: Feasibility of Implementing an Interactive Sleep Workshop at a Division I School

Sleep concerns are prevalent among student-athletes and can result in impaired athletic and academic performance. The current study investigated the feasibility and effectiveness of a brief sleep workshop for student-athletes. Athletes (N = 152) completed baseline and follow-up questionnaires (n = 104) after the intervention. Greater than half of the athletes (51%) who attended the workshops and followup reported at least one change in sleep behaviors. Results revealed a significant decrease in sleepiness from baseline to follow-up and an improvement in daytime functioning. Although athletes reported an increase in problematic sleep hygiene behaviors, they recorded significant increases in sleep knowledge from baseline to follow-up, which was maintained at the second follow-up. These longitudinal data provide evidence that a brief psychoeducation sleep workshop for student-athletes is promising for improving sleep knowledge and daily functioning.
Histone Deacetylase Activity Is Necessary for Oligodendrocyte Lineage Progression

Gene expression can be modulated by chromatin changes induced by histone acetylation and deacetylation. Acetylation of histone lysine residues by acetyltransferases is associated with transcriptionally active chromatin, whereas the removal of acetyl groups by histone deacetylases (HDACs) correlates with repressed chromatin. Recent evidence has shown that histone deacetylation is responsible for restricting neuronal gene expression, whereas histone acetylation is necessary for astrocytic differentiation We now asked whether histone acetylation or deacetylation was necessary for oligodendrocyte differentiation. Neonatal rat cortical progenitors were kept proliferating and undifferentiated in the presence of mitogens and induced to stop proliferating and differentiate into oligodendrocytes by mitogen removal. Histone deacetylation was observed during the temporal window between exit from the cell cycle and onset of differentiation, which was characterized by acquisition of branched morphology and myelin gene expression. Blocking HDAC activity during this critical window using the inhibitor trichostatin A (TSA) prevented the progression of progenitors into mature oligodendrocytes. TSA-treated progenitors were able to exit from the cell cycle but did not progress to oligodendrocytes. Their development was arrested at the progenitor stage, characterized by simple morphology and lack of myelin gene expression. The effect of TSA on progenitor differentiation was lineage specific, because TSA did not affect the ability of these cells to differentiate into type II astrocytes when cultured in the presence of serum. From these data, we conclude that histone deacetylation is a necessary component of the oligodendrocyte differentiation program.
Two lectures on heavy quark production in hadronic collisions

These lectures present a pedagogical introduction to the physics of heavy-flavour production in hadronic collisions. The first lecture gives the theoretical background, with a discussion of leading-order calculations and of the effects of next-to-leading-order corrections. The origin and implications of the large logarithmic corrections appearing at this order are presented in an elementary way. The second lecture provides a survey of current experimental data on charm and bottom production, and describes their comparison with theoretical predictions. We emphasize the role played by some non-perturbative effects in the determination of charm distributions, and study the theoretical systematic uncertainties which affect our predictions.

SHARP-EDGES METHOD IN ARABIC TEXT STEGANOGRAPHY NUUR

One of the issues that arise in the text steganography is the capacity of hiding secret bit. Focusing in Arabic text steganography we propose a sharp-edges method to encounter the issue. This new method will hide the secret bits in the sharp-edges for each character in the Arabic text document. The main processes involved are identifying sharp-edges in the cover-text, secret message preparation to be hidden as a binary string and lastly, the bit hiding process. The experiments show that the capacity percentage used to hide the secret bit was increased up to 37.8%, resolving the capacity issue. The stego-text for this method has high invisibility, and therefore it is possible to be published publicly. We introduce keys to determine the possition of the secret bit randomly. This method utilizes the advantages of the Arabic text for steganography and can also be implemented to the same text scripting of languages such as Jawi, Persian or Urdu.
CUSTOMER SATISFACTION IN MOBILE PHONE SERVICES IN BANGLADESH: A SURVEY RESEARCH

This study seeks to explore customer satisfaction and its influencing factors of the mobile phone operation industry in Bangladesh. Data were collected through a questionnaire survey form a diversified representative sample. An iterated factor analysis with principal component analysis (PCA) and structural equation modeling (SEM) including measurement model and structural model were applied to analyze data. The empirical results demonstrate that service quality and fair price have indirect influence on customer satisfaction of a mass service industry (i.e., mobile phone operators) through perceive value. Perceived value has mediating role between quality, charge fairness and satisfaction. Furthermore, result shows that fair price has positive direct impact on customer satisfaction, whereas, the results did not find any significant direct impact of service quality on customer satisfaction. Mobile phone operators are recommended to formulate operations and marketing strategies that focus on expectations of customers to enhance level of satisfaction. Similar industries may reveal similar relationship features in respect to these relationship constructs, if they are under similar category.
Cramer 51 Digital Airborne Camera Performance – The DGPF Test

In 2008 a comprehensive project on the empirical investigation of the performance of digital photogrammetric airborne cameras was performed under the umbrella of the German Society of Photogorammetry, Remote Sensinsing and Geoinformation (DGPF). This project includes empirical test flights in the test field Vaihingen/Enz. Data are currently under investigation, where different working topics have been defined to structure this evaluation phase. More than 25 institutions are already actively participating. In addition to previously done projects, where main focus typically was laid on the geometric sensor performance only, the DGPF project also aims on the analysis of radiometric performance and the investigation of product quality like digital photogrammetric surface models and manual stereo plotting. This paper will introduce the project itself and present some of the findings, mainly focussing on the geometrical topics first. Even though the processing of the very complex data sets is not yet finished, the high potential of digital airborne imaging is already proven.
Developmental Transformation of the Release Modality at the Calyx of Held Synapse

Ca2+ influx through voltage-gated Ca2+ channels (VGCCs) into nerve terminals triggers vesicular fusion and neurotransmitter release. However, it is unknown whether the coupling between VGCCs and synaptic vesicles (SVs) is developmentally regulated. By paired patch-clamp recordings from the mouse calyx of Held synapse, we show here that injection of a Ca2+ buffer with slow binding kinetics (EGTA; 10 mm) potently attenuated transmitter release in young terminals [postnatal day 8 (P8)-P12] but produced little effect in older ones (P16-P18), suggesting that SVs in young synapses are loosely coupled to VGCCs, but the coupling tightens spatially during maturation. Using voltage paradigms that specifically recruit different numbers of VGCCs without changing the driving force for Ca2+, we found that the Ca2+ cooperativity (m), estimated from graded presynaptic Ca2+ currents and transmitter release, was much higher in P8-P12 synapses (m = 4.8-5.5) than that in P16-P18 synapses (m = 2.8-3.0; 1 mm [Ca2+]o), implying that the number of VGCCs or Ca2+ domains required for release of single SVs decreases with maturation. The m value remained significantly different between two age groups at 35°C or in 2 mm [Ca2+]o and was independent of postsynaptic receptor desensitization. We demonstrated that release from P8-P12 terminals involved both N- and P/Q-type VGCCs, but P/Q-type-associated release sites specifically displayed low m values. These results suggest a developmental transformation of the release modality from “microdomain,” involving cooperative action of many loosely coupled N- and P/Q-type VGCCs, to “nanodomain,” in which opening of fewer tightly coupled P/Q-type VGCCs effectively induce a fusion event. Spatial tightening improves the release efficiency and is likely a critical step for the development of high-fidelity neurotransmission in this and other central synapses.
Land-Cover/Land-Use Changes in the Derekolli Catchment of the South Welo Zone of Amhara Region, Ethiopia

A land-cover analysis carried out in the catchment of Derekolli stream, using image analysis and GIS technologies, in conjunction with data collected through field surveys, revealed two types of changes, i.e., land-cover modification and conversion. The shrubland, which apparently formed the climax vegetation of the study site, and accounted for 16.4 % of the watershed in 1957, disappeared at the rate of 1.6 and 0.31 per cent per year from 1957 to 1986, and from 1986 to 2000, respectively. This change involved a gradual thinning of the shrub and its modification to shrub grassland, and then grassland, due to the selective cutting of the woody biomass for fuelwood and charcoal production. A significant conversion from natural vegetation cover to cropland was observed only between 1957 and 1986, where the cultivated land expanded by 7 per cent. There was very little change in the cropland area since 1986, as most of the land suitable for cultivation was already in use and the limit for expansion had almost been reached. The other type of conversion, i.e., the change from cultivated land to urban area, was insignificant since the land taken up by the emerging town, together with the roads accounted for less than 1.5 per cent of the total area of the catchment.
University-School-Center Collaboration in Support of Identifying and Treating Minority Children with Hearing, Language, or Speech Difficulties: Fulfilling the Spirit of "No Child Left Behind".

St. Martin Hall, a demonstration school affiliated with Our Lady of the Lake University in San Antonio, Texas, collaborated with the Harry Jersig Center to test students for speech and language difficulties or hearing loss. A significant number of the children were from economically disadvantaged homes. Most of the children were Hispanic. Audiologists and speech pathologists assisted by graduate students from Our Lady of the Lake University conducted screenings of 108 children over a four-month period. Children who failed any screening were referred for further testing and possible intervention. This collaboration demonstrates how good will, cooperation, communication and energy can do much to improve the lives of children when school and parent resources are limited. ________________________ lassrooms today are filled with an “educational hum. ” Noise is everywhere! What would it be like if you were not able to hear your teacher teaching a phonics lesson when all of the other children could hear perfectly? That is a problem that many children face in schools every day. Statistics show that 15% of children from 6 to 19 years of age have some degree of hearing loss in one or both ears. A Vanderbilt University study found a 14.3% rate of hearing loss in a national sample of children who were of school age. The American Speech Language Hearing Association reports that more that 1 million U.S. children have some degree of hearing loss (Black, 2003, May). The Gallaudet Research Institute indicates that 40% of children with hearing loss have additional disabilities (GRI, 2003a, 2003b). This concern has national significance that C NATIONAL FORUM OF TEACHER EDUCATION JOURNAL-ELECTRONIC 2___________________________________________________________________________________ reaches far beyond the individual students and the demonstration campus of this study. The “No Child Left Behind Act” mandates that every child be on grade level by grade three. Educators nationwide are seeking ways to reduce the number of children in our special education classes but have they considered that a child’s learning problems may be due to a hearing loss? Considering these realities investigators wanted know the following: 1) Do these statistics accurately represent what is happening within the economically disadvantaged minority population of St. Martin Hall? 2) What is the impact of hearing, speech and language difficulties on future learning and placement of each St. Martin Hall student? ” and 3) How could the special relationship among a university, its demonstration school and a center specializing in hearing, speech and language disorders lead to collaborative intervention to identify and intervene on behalf of students with hearing or language difficulties early in their academic lives?
An area-efficient VLSI architecture for decoding of Reed-Solomon codes

This paper presents a new pipelined VLSI array for decoding Reed-Solomon (RS) codes. The architecture is designed based on the modified time-domain Berlekamp-Massey algorithm incorporated with the remainder decoding concept. A prominent feature of the proposed system is that, for a t-error-correcting RS code with block length n, it involves only 2t consecutive symbols to compute a discrepancy value in the decoding process, instead of n consecutive symbols used in the previous RS decoders based on the same algorithm without using the remainder decoding concept. The proposed RS decoder reaches an average decoding rate of one data symbol per clock cycle. As compared to a similar pipelined RS decoder with the same decoding rate, it gains significant improvements in hardware complexity and latency.
An Improved Particle Swarm Optimization Using Particle Reliving Strategy

The particle swarm optimization (PSO) is one of the best efficient algorithms. It has obtained more and more attention and has been applied in many fields, such as machine design and circuit design. But it also has some disadvantages, such as prematurely and difficultly to convergence. To improvement the performance of PSO, particle reliving strategy is proposed. With this strategy, a criterion is used to judge whether the particle relives. If so, the particle will relive just like that when the algorithm initials. Some benchmark functions are used to illuminate that the successful probability of PSO is improved with particle reliving.
Carbon Monoxide: Endogenous Production, Physiological Functions, and Pharmacological Applications

Over the last decade, studies have unraveled many aspects of endogenous production and physiological functions of carbon monoxide (CO). The majority of endogenous CO is produced in a reaction catalyzed by the enzyme heme oxygenase (HO). Inducible HO (HO-1) and constitutive HO (HO-2) are mostly recognized for their roles in the oxidation of heme and production of CO and biliverdin, whereas the biological function of the third HO isoform, HO-3, is still unclear. The tissue type-specific distribution of these HO isoforms is largely linked to the specific biological actions of CO on different systems. CO functions as a signaling molecule in the neuronal system, involving the regulation of neurotransmitters and neuropeptide release, learning and memory, and odor response adaptation and many other neuronal activities. The vasorelaxant property and cardiac protection effect of CO have been documented. A plethora of studies have also shown the importance of the roles of CO in the immune, respiratory, reproductive, gastrointestinal, kidney, and liver systems. Our understanding of the cellular and molecular mechanisms that regulate the production and mediate the physiological actions of CO has greatly advanced. Many diseases, including neurodegenerations, hypertension, heart failure, and inflammation, have been linked to the abnormality in CO metabolism and function. Enhancement of endogenous CO production and direct delivery of exogenous CO have found their applications in many health research fields and clinical settings. Future studies will further clarify the gasotransmitter role of CO, provide insight into the pathogenic mechanisms of many CO abnormality-related diseases, and pave the way for innovative preventive and therapeutic strategies based on the physiologic effects of CO.
The Importance of the Therapeutic Alliance When Working with Sexual Offenders

While there is general agreement in the literature regarding the importance of the therapeutic alliance in psychological interventions with people, the forensic context raises some unique challenges. This paper will discuss the significance of the therapeutic alliance in interventions with offenders, especially sexual offenders and the impact on treatment efficacy and change. Therapist characteristics will also be reviewed as well as some of the obstacles and challenges present in a correctional setting, which can impact on the therapeutic alliance. Lastly, the role of transference and countertransference is also considered.
Competitive Semantic Memory Retrieval: Temporal Dynamics Revealed by Event-Related Potentials

Memories compete for retrieval when they are related to a common retrieval cue. Previous research has shown that retrieval of a target memory may lead to subsequent retrieval-induced forgetting (RIF) of currently irrelevant competing memories. In the present study, we investigated the time course of competitive semantic retrieval and examined the neurocognitive mechanisms underlying RIF. We contrasted two theoretical accounts of RIF by examining a critical aspect of this memory phenomenon, namely the extent to which it depends on successful retrieval of the target memory. Participants first studied category-exemplar word-pairs (e.g. Fruit—Apple). Next, we recorded electrophysiological measures of brain activity while the participants performed a competitive semantic cued-recall task. In this task, the participants were provided with the studied categories but they were instructed to retrieve other unstudied exemplars (e.g. Fruit—Ma__? ). We investigated the event-related potential (ERP) correlates of retrieval success by comparing ERPs from successful and failed retrieval trials. To isolate the ERP correlates of continuous retrieval attempts from the ERP correlates of retrieval success, we included an impossible retrieval condition, with incompletable word-stem cues (Drinks—Wy__) and compared it with a non-retrieval presentation baseline condition (Occupation—Dentist). The participants’ memory for all the studied exemplars was tested in the final phase of the experiment. Taken together, the behavioural results suggest that RIF is independent of target retrieval. Beyond investigating the mechanisms underlying RIF, the present study also elucidates the temporal dynamics of semantic cued-recall by isolating the ERP correlates of retrieval attempt and retrieval success. The ERP results revealed that retrieval attempt is reflected in a late posterior negativity, possibly indicating construction of candidates for completing the word-stem cue and retrieval monitoring whereas retrieval success was reflected in an anterior positive slow wave.
It’s a Matter of Mind! Cognitive Functioning Predicts the Athletic Performance in Ultra-Marathon Runners

The present study was aimed at exploring the influence of cognitive processes on performance in ultra-marathon runners, providing an overview of the cognitive aspects that characterize outstanding runners. Thirty runners were administered a battery of computerized tests right before their participation in an ultra-marathon. Then, they were split according to the race rank into two groups (i.e., faster runners and slower runners) and their cognitive performance was compared. Faster runners outperformed slower runners in trials requiring motor inhibition and were more effective at performing two tasks together, successfully suppressing the activation of the information for one of the tasks when was not relevant. Furthermore, slower runners took longer to remember to execute pre-defined actions associated with emotional stimuli when such stimuli were presented. These findings suggest that cognitive factors play a key role in running an ultra-marathon. Indeed, if compared with slower runners, faster runners seem to have a better inhibitory control, showing superior ability not only to inhibit motor response but also to suppress processing of irrelevant information. Their cognitive performance also appears to be less influenced by emotional stimuli. This research opens new directions towards understanding which kinds of cognitive and emotional factors can discriminate talented runners from less outstanding runners.
Acute PD with Rigid Catheters : A Relook

Peritoneal Dialysis (PD) has been an underutilized modality in the treatment of Acute Kidney Injury (AKI). Concerns regarding clearance, fluid removal, infection, complications of therapy, and the hypercatabolic state of AKI has led to PD falling into disrepute. Recent studies have challenged this notion of ineffectiveness. The lower cost, and simplicity of the procedure makes it a particularly attractive option for the developing world which may lack even basic HD facilities, and patients continue to die for want of Renal Replacement Therapy (RRT). We present a review of the available literature about PD in the AKI setting with special reference to the developing world, including the procedure, costs, and effectiveness of the treatment. We also describe the procedure in detail to help ‘hand hold’ physicians interested in performing this lifesaving procedure.
Warming increases the top-down effects and metabolism of a subtidal herbivore

Ecological theory and experiments indicate that warming can increase the relative strength of top-down effects via alterations to metabolic rates in several different systems, thereby resulting in decreased plant biomass at higher temperatures. However, the general influence of increased environmental temperature on top-down effects is not well understood in systems where organisms experience relatively large variation in temperature. Rapid ocean temperature changes are pervasive throughout the Galápagos Islands due to upwelling and downwelling of internal waves, ENSO events and seasonality. We measured the effect of large, but not uncommon, water temperature variation on the metabolism and grazing rate of a common subtidal herbivore and on photosynthesis of their algal prey in the Galápagos Islands in July 2012. We found that green urchin consumption and metabolism were greater at the higher temperature treatment (28°C), resulting in significantly less algal biomass. Our result that warming increased green urchin metabolic rates, even in a highly dynamic system, provides further support for a mechanistic link between environmental temperature and feeding rates. And further, our findings suggest individual response to temperature results in changes in top-down effects. And if this response is maintained over longer-time scales of days to weeks, this could translate to alterations of larger-scale ecological patterns, such as primary producer community composition and structure.
