Physical and Technical Comparisons between Various-Sided Games within Professional Soccer

Abstract This study compared the technical activity and physical movements of various-sided games within professional soccer. It also examined the test-retest reliability of sided games using various numbers of players. 10 elite male players from a Scottish Premier League performed small- (SSGs: 4 vs. 4), medium- (MSGs: 5 vs. 5 to 8 vs. 8) and large- (LSGs: 9 vs. 9 to 11 vs. 11) sided games each lasting for 3×5 min. Results show significant physical differences (p<0.05) between SSGs, MSGs and LSGs for most of the variables measured. It was shown that SSGs induce a significantly faster playing speed when compared to MSGs and LSGs (150.5 vs. 108.3 vs. 120.4 m.min−1, p<0.01) but significantly less (p<0.01) repeated high-intensity efforts (0.88 vs. 4.40 m), high-intensity running (7 vs. 39 m) and sprint distance (0 vs. 11 m) when compared to LSGs. Findings also revealed significant differences (p<0.05) between SSGs, MSGs and LSGs in technical demands (passes, dribbles, shots, headers). High levels of reproducibility (ICC=0.99) were yielded when using the same-sided games, pitch sizes and possession rules. This study provided information on different-sided games to facilitate its use as part of a periodised weekly structure.
Mutational studies on the alpha-sarcin loop of Escherichia coli 23S ribosomal RNA.

The alpha-sarcin loop, located in domain VI of Escherichia coli 23S rRNA, is a universally conserved sequence involved in the binding of elongation factors to the ribosome and is the site of action of ribosome-inactivating proteins. Six mutations were created in this loop with the aim of establishing whether the mutant 23S rRNA could be assembled into functional ribosomes. In order to distinguish between plasmid-derived (mutant) and chromosome-derived (wild-type) 23S rRNAs, an oligonucleotide tag sequence was introduced into the plasmid-borne 23S rRNA gene. The tag sequence had no apparent effect on ribosome assembly or function. Two of the bases mutated (at positions A2660 and G2661) have been implicated in the binding of both elongation factor Tu and elongation factor G to the ribosome [Moazed, D. , Robertson, J. M. & Noller, H. F. (1988) Nature 334, 362-364]. A further two bases (at positions C2658 and G2663) have been proposed to form a Watson-Crick base pair involved in the formation of a tetraloop structure required for ribosome function [Szewczak, A. A. , Moore, P. B. , Chan, Y. L. & Wool, I. G. (1993) Proc. Natl Acad. Sci. USA 90, 9581-9585]. It is inferred that the identity of the bases at positions 2658 and 2663 are of critical importance for ribosome structure and function, and that this function cannot be restored by a second mutation which potentially restores a Watson-Crick base pair, but with reversed position. Of five single mutants (each mutant containing one of the mutations C2658G, A2660G, G2661A, G2663C and G2664C) and one double mutant (containing both mutations C2658G and G2663C) only the two mutants with the single mutations G2661A and G2664C were incorporated into ribosomes at a level comparable to that of 23S rRNA expressed from a wild-type plasmid. However, the G2664C mutation resulted in a decrease in growth rate and a gradual loss of viability. rRNAs containing the G2663C single mutation and the C2658G and G2663C double mutation showed reduced incorporation into 50S subunits and these did not enter into ribosome couples.
Height of Christmas Tree Drawings as a Function of Time

Thirty male and 30 female students in Grade 6 of a local public school were asked to draw Christmas Trees on October 31, November 28, December 19, January 13, February 13, and March 13. Analysis of the height (cm.) of these drawings indicated that Christmas Trees drawn in November and December were significantly larger than those at other times (p < .01). There were no over-all sex differences. Sex × Trial interactions indicated that the main trial effect was due to the girls drawing the largest Christmas Tree in December and the boys, the largest in November. A control group drawing only trees other than Christmas Trees, showed no differences in size of drawings as a function of time or sex. Similarly, the experimental groups drawing trees other than Christmas Trees in October and March exhibited no statistically significant differences in size of drawing as a function of either sex or time. Therefore, the hypothesis that the time-object relationship evident in previous studies was effective in this type of task was supported. An interesting finding suggested that the size of Christmas Tree drawings was reduced by boys and increased by girls (both at a statistically significant level) as a function of Valentine's Day.
Drug treatment of older people with affective disorders in the community: lessons from an attempted clinical trial

Depression and phobic anxiety disorders are the most common psychiatric disorders in people aged 65 and over. SSRI antidepressants are effective in treating both conditions in younger people, and in treating depression in hospital samples of older subjects. No studies have investigated the efficacy of SSRIs in older people with these conditions living in the community.

Reverse logistics assessment in the automotive industry: A case study at Volvo Group

The world is facing an era of extreme competitiveness regarding business environments. Actors in the Supply Chain networks do not scape to this phenomenon. Firms can no longer compete as individuals to be profitable. To be competitive, the different players within a Supply Chain (i.e. suppliers, manufacturers, dealers) have to share goals and objectives, acting as one player. Supply Chains have the necessity to shift to what is known as Closed- Loop Supply Chain, where the product life is extended even after the selling. The recovery of these products and their further treatments (i.e. remanufacturing, repairing, etc.) play a massive role in firms´ total revenues. In the automotive industry, companies do not seem to be managing their reverse logistics in a proper way, and this constitutes a big problem. Reverse logistics has to be further take into consideration, as it ensure the end-customer satisfaction, as well as it ensure the availability of products in the aftermarket. This thesis was performed in the Logistics Service Development department under the Volvo Group Trucks Operations division, in Gothenburg, Sweden. Volvo Group is a global and multinational company, considered a leading transport solution manufacturer. The firm wanted to study how the reverse logistics were managed, which led to the following aim: assess the reverse logistics systems that are currently being employed in the focal company and suggest improvements. To fulfill the requirements set by the purpose, the actual practices of the company were studied, the key factors influencing the returns were identified and suggestions were provided. Semi-structured interviews both internal (within the company) and external (3PL and Dealers), internal documentation, direct observations and collection of operational data served the author to assess the purpose. The study of the current situation led the author to identify that there was a lack of steering decisions regarding reverse flows, as well as high returns rates and poor systems steering the returns. Five key factors were identified to be the root of the flaws of the current situation: Communication, Dealer´s experiences; Returns planning and policies; Lead times; and Performance measurements. Improvements were suggested regarding these five factors: Enhance communication (e.g. workshops with dealers); Improve Dealer´s Experience through building a new system; Change the returns planning and policies; Improve lead times (e.g. Stabilize lead times, same day deliveries); and Establish performance measurements (e.g. Track and Trace; KPIs). Thus, this case study provides a replicable framework to enhance the performance of the reverse logistics in the automotive industry.
Combining few neural networks for effective secondary structure prediction

The prediction of secondary structure is treated with a simple and efficient method. Combining only three neural networks, an average Q/sub 3/ accuracy prediction by residues of 75.93% is achieved. This value is better than the best results reported on the same test and training database, CB396, using the same validation method. For a second database, RS126, an average Q/sub 3/ accuracy of 74.13% is attained, which is better than each individual method, being defeated only by CONSENSUS, a rather intricate engine, which is a combination of several methods. The networks are trained with RPROP an efficient variation of the back-propagation algorithm. Five combination rules are applied independently afterwards. Each one increases the accuracy of prediction by at least 1%, due to the fact that each network used converges to a different local minimum. The Product rule derives the best results. The predictor described here can be accessed at http://biolab.cin. ufpe.br/tools/.
Sharenting: Making Decisions about Other's Privacy on Social Networking Sites

Sharenting refers to the trend of oversharing photos of children on Social Networking Sites (SNS) by parents. At the same time, this trend is increasingly controversial as parents have to balance their right to share and children’s privacy interest. Against this background we investigate parents’ underlying decision process and the applied strategies to mitigate children’s privacy risks when disclosing pictures of them on SNS. Based on a qualitative online survey among 220 mothers, we shed light on the antecedents of parental sharing, resulting in a comprehensive overview to guide future research and advise SNS providers. Results show that, among others, mothers reveal personal information about their children to participate in social interactions and to show their pride. On the flipside, they care about their children’s privacy and the risk of their children being embarrassed or hurt. Beyond that, they apply several costmitigating strategies like face-covering and blurring of identifiable information.
Cross-Layer Design for Multi-Antenna Ultra-Wideband Systems

Title of Dissertation: CROSS-LAYER DESIGN FOR MULTI-ANTENNA ULTRA-WIDEBAND SYSTEMS Wipawee Siriwongpairat, Doctor of Philosophy, 2005 Dissertation directed by: Professor K. J. Ray Liu Department of Electrical and Computer Engineering Ultra-wideband (UWB) is an emerging technology that offers great promises to satisfy the growing demand for low cost and high-speed digital wireless home networks. The enormous bandwidth available, the potential for high data rates, as well as the potential for small size and low processing power along with low implementation cost, all present a unique opportunity for UWB to become a widely adopted radio solution for future wireless home-networking technology. Nevertheless, in order for UWB devices to coexist with other existing wireless technology, the transmitted power level of UWB is strictly limited by the FCC spectral mask. Such limitation poses significant design challenges to any UWB system. This thesis introduces various means to cope with these design challenges. Advanced technologies including multiple-input multiple-output (MIMO) coding, cooperative communications, and cross-layer design are employed to enhance the performance and coverage range of UWB systems. First a MIMO-coding framework for multi-antenna UWB communication systems is developed. By a technique of band hopping in combination with jointly coding across spatial, temporal, and frequency domains, the proposed scheme is able to exploit all the available spatial and frequency diversity, richly inherent in UWB channels. Then, the UWB performance in realistic UWB channel environments is characterized. The proposed performance analysis successfully captures the unique multipath-rich property and random-clustering phenomenon of UWB channels. Next, a cross-layer channel allocation scheme for UWB multiband OFDM systems is proposed. The proposed scheme optimally allocates subbands, transmitted power, and data rates among users by taking into consideration the performance requirement, the power limitation, as well as the band hopping for users with different data rates. Also, an employment of cooperative communications in UWB systems is proposed to enhance the UWB performance and coverage by exploiting the broadcasting nature of wireless channels and the cooperation among UWB devices. Furthermore, an OFDM cooperative protocol is developed and then applied to enhance the performance of UWB systems. The proposed cooperative protocol not only achieves full diversity but also efficiently utilizes the available bandwidth.

Shared and distinct functions of RAGS and ELF‐1 in guiding retinal axons

Two ligands for Eph‐related receptor tyrosine kinases, RAGS and ELF‐1, have been implicated in the control of development of the retinotectal projection. Both molecules are expressed in overlapping gradients in the tectum, the target area of retinal ganglion cell axons. In two in vitro assays ELF‐1 is shown to have a repellent axon guidance function for temporal, but apparently not for nasal axons. RAGS on the other hand is repellent for both types of axons, though to different degrees. Thus, RAGS and ELF‐1 share some and differ in other properties. The biological activities of these molecules correlate with the strength of interaction with their receptors expressed on RGC axons. The meaning of these findings for guidance of retinal axons in the tectum is discussed.
DEVELOPMENT OF COMPETENCE FOR SUSTAINABLE MANUFACTURING BY USING SERIOUS GAMES

This paper will present preliminary results of the EU-funded FP7 integrated project TARGET. The main aim of the project is to develop a novel technology-enhanced learning platform that provides learners with a responsive environment that addresses the rapid, personalized competence development and the sharing of experiences associated with introducing sustainability into a manufacturing enterprise. The main objectives of the paper are to deduce specialized sustainability-related competences for managers and to convert them into a virtual game scenario. Besides the research approach of deriving the competences, critical incidents in the game will be presented. The findings and potential application will be demonstrated in a case based on Life Cycle Assessment (LCA).
What do we know about consumer m-shopping behaviour?

Purpose The purpose of this paper is to provide a review of the mobile shopping (m-shopping) acceptance literature to bring international marketing and consumer research attention to m-shopping acceptance factors and limitations in current understandings to propose recommendations for further academic and retailing attention. Design/methodology/approach Keyword searches identified the consumer-focused literature across mobile commerce, m-shopping, mobile browsing and mobile purchasing, published in English language journals. A classification framework is created and a time frame is established to provide a more focused direction for research. Findings Despite the growing popularity of consumers adopting m-shopping activities and the increasing academic attention, consumer m-shopping utilisation remains low and research into its causes remains in its infancy. This paper has subsequently identified a variety of recommendations for further research, including further insights into perceived risk, user vs non-user behaviours, the multi-stage shopping process, incorporation of time considerations and theoretical development. Originality/value There has yet been a review of the m-shopping literature collaborating literary findings and limitations in the consumer m-shopping environment. Three major themes arise in this paper. First, there are a variety of factors affecting consumer willingness to accept m-shopping which are often incorporated in existing theory in a sporadic manner. Second, factors can create positive and/or negative consumer perceptions, requiring further insight. Finally, research limitations predominantly surround theoretical and methodological constraints, prompting for wider geographical and more longitudinal approaches to research.
Caring for her: the influence of presumed influence on female consumers’ attitudes towards advertising featuring gender-stereotyped portrayals

ABSTRACT This study investigates how presumed influence on others affects women's evaluations of advertising featuring gender stereotypes. Previous research has largely overlooked the social context of the reactions to gender stereotypes. Addressing that gap, this study draws on the influence of presumed influence model to proposed that female consumers believe that other women are negatively affected by advertising that contains gender-stereotyped portrayals. This perception is hypothesized to influence ad and brand attitudes as consumers ‘punish’ the brand for hurting others. The results of two experimental studies featuring stereotyped and non-stereotyped advertising portrayals indicate that the hypothesis holds for two types of stereotype components (physical characteristics and role behaviour). This new theoretical perspective to the literature on gender stereotypes in advertising, one that helps to explain why many women dislike gender stereotypes in advertising even though those stereotypes often have limited impact on them personally.
Aquatic training and detraining on fitness and quality of life in fibromyalgia.

PURPOSE To evaluate the effects of a 12-wk period of aquatic training and subsequent detraining on health-related quality of life (HRQOL) and physical fitness in females with fibromyalgia. METHODS Thirty-four females with fibromyalgia were randomly assigned into two groups: an exercise group, who exercised for 60 min in warm water, three times a week (N = 17); and a control group, who continued their habitual leisure-time activities (N = 17). HRQOL was assessed using the Short Form 36 questionnaire and the Fibromyalgia Impact Questionnaire. Physical fitness was measured using the following tests: Canadian Aerobic Fitness, hand grip dynamometry, 10-m walking, 10-step stair climbing, and blind one-leg stance. Outcomes were measured at baseline, after treatment, and after 3 months of detraining. RESULTS After 12 wk of aquatic exercise, significant positive effects of aquatic training were found in physical function, body pain, general health perception, vitality, social function, role emotional problems and mental health, balance, and stair climbing. After the detraining period, only the improvements in body pain and role emotional problems were maintained. CONCLUSION The present water exercise protocol improved some components of HRQOL, balance, and stair climbing in females with fibromyalgia, but regular exercise and higher intensities may be required to preserve most of these gains.
Coenzyme Q10 suppresses oxLDL-induced endothelial oxidative injuries by the modulation of LOX-1-mediated ROS generation via the AMPK/PKC/NADPH oxidase signaling pathway.

SCOPE The lectin-like oxidized low-density lipoprotein receptor (LOX-1) is one pivot receptor for oxidized low-density lipoprotein (oxLDL) in human endothelial cells. Co-enzyme Q10 (Co Q10) has been widely used in clinical intervention. However, the molecular mechanisms underlying its protective effects against oxidative stress in endothelial cells are still largely unknown. This study was designed to test the hypothesis that Co Q10 mitigates oxLDL-induced endothelial oxidative injuries via modulation of LOX-1-mediated reactive oxygen species (ROS) generation and explored the role of AMP-activated protein kinase (AMPK), a negative regulator of NADPH oxidase. METHODS AND RESULTS Human umbilical vein endothelial cells (HUVECs) were pretreated with Co Q10 and then incubated with oxLDL for 24 h. Co Q10 attenuated oxLDL-elicited LOX-1 expression and ROS generation by suppression of NADPH oxidase activation. Co Q10 rescued dephosphorylation of AMPK caused by oxLDL that in turn led to an activation of NADPH oxidase by PKC. The results were confirmed using AMPK siRNA. Moreover, oxLDL-suppressed Akt/eNOS and enhanced p38 phosphorylation, which in turn activated NF-κB pathway. These detrimental events were ameliorated by Co Q10. CONCLUSION These results provide new highlight onto the possible molecular mechanisms of how Q10 suppresses oxLDL-induced endothelial oxidative injuries by the modulation of LOX-1-mediated ROS generation via the AMPK/PKC/NADPH oxidase signaling pathway.
All thalamocortical neurones possess a T‐type Ca2+‘window’ current that enables the expression of bistability‐mediated activities

1 The existence of a non‐negligible steady‐state (‘window’) component of the low threshold, T‐type Ca2+current (IT) and an appropriately large ratio of IT to ILeak conductance (i.e. gT/gLeak) have been shown to underlie a novel form of intrinsic bistability that is present in about 15 % of thalamocortical (TC) neurones. 2 In the present experiments, the dynamic clamp technique was used to introduce into mammalian TC neurones in vitro either an artificial, i.e. computer‐generated, IT in order to enhance endogenous IT, or an artificial inward ILeak to decrease endogenous ILeak. Using this method, we were able to investigate directly whether the majority of TC neurones appear non‐bistable because their intrinsic ionic membrane properties are essentially different (i.e. presence of a negligible IT‘window’ component), or simply because they possess a gT or gLeak conductance that is insufficiently large or small, respectively. 3 The validity of the dynamic clamp arrangement and the accuracy of artificial IT were confirmed by (i) recreating the low threshold calcium potential (LTCP) with artificial IT following its block by Ni2+ (0.5–1 mM), and (ii) blocking endogenous LTCPs with an artificial outward IT. 4 Augmentation of endogenous IT by an artificial analog or introduction of an artificial inward ILeak transformed all non‐bistable TC neurones to bistable cells that expressed the full array of bistability‐mediated behaviours, i.e. input signal amplification, slow oscillatory activity and membrane potential bistability. 5 These results demonstrate the existence of a non‐negligible IT‘window’ component in all TC neurones and suggest that rather than being a novel group of neurones, bistable cells are merely representative of an interesting region of dynamical modes in the (gT, gLeak) parameter space that may be expressed under certain physiological or pathological conditions by all TC neurones and other types of excitable cells that possess an IT‘window’ component with similar biophysical properties.
