Transformational leader integrity: an investigation of coach social cognition

The majority of psychological research investigating leader integrity has relied on self or other report methods as the primary means of data collection. While such an approach has advanced the literature, due to the theorised deceptive and manipulative nature of leaders lacking in integrity, prominent theorists (Barling, Christie and Turner, 2008) have called for alternative measures that are less prone to socially desirable responding. As no prior research had examined the integrity of sporting leaders, the present thesis began by examining the antecedent cognitive processes of expert football managers. Building upon this exploration, an implicit association test was developed within studies two and three. Results suggest that the instrument is capable of assessing automatic attitudes towards leader integrity, is more sensitive than existing measures, offers support for concurrent and convergent validity, demonstrates good test-retest reliability, good internal consistency, and is a predictor of player reported commitment. In sum, the present research has sought to understand the phenomena of leader integrity from the perspective of social cognition. The result of these investigations is a robust, sensitive, and complimentary measure of leader integrity, which will assist researchers to better understand the processes that underpin leader integrity.
Can 8 Weeks of Training in Female Swimmers Affect Active Drag

Hydrodynamic drag is the force that a swimmer has to overcome in order to maintain his movement through water and is influenced by velocity, shape, size and the frontal surface area Thus, the aim of this study was to assess the effects of 8 weeks of training on active drag in young female swimmers. 8 female age group swimmers belonging to the same swimming club participated in this study. Active drag measurements were conducted in two different trials: at the beginning of the season and after 8 weeks of training. The velocity perturbation method was used to determine active drag in front crawl swimming. After 8 weeks of training, mean active drag decreased, although no significant differences were found between the two trials. No significant differences were observed in swimming velocity between the two trials. It seems that 8 weeks of swimming training were not enough to allow significant improvements on swimming technique. One can recommend that specific training sets concerning technique correction and improvement in young swimmers should be a main aim during training planning.
Unique Matching Patterns in Remarriage

Educational assortative mating is a crucial aspect of marriage formation because it confers benefits such as improved health and well-being, affects economic standing, and reflects the level of gender equity within marriage. However, little is known about educational assortative mating patterns in remarriage. Using data from the National Longitudinal Survey of Youth, 1979 cohort, this study addresses this shortcoming in two ways. First, I compare educational assortative mating patterns in first and second marriages. Second, I address characteristics associated with homogamy, hypergamy, and hypogamy in remarriage. The results show that assortative mating patterns in remarriage are distinct from those in first marriage, remarriage patterns are unique by educational attainment and gender, and these patterns are not explained by differences in income, age, or parental status. The results illustrate the need for theories which specifically address the unique nature of remarriage in the United States.
Experience-Related Changes in Place Cell Responses to New Sensory Configuration That Does Not Occur in the Natural Environment in the Rat Hippocampus

The hippocampal formation (HF) is implicated in a comparator that detects sensory conflict (mismatch) among convergent inputs. This suggests that new place cells encoding the new configuration with sensory mismatch develop after the HF learns to accept the new configuration as a match. To investigate this issue, HF CA1 place cell activity in rats was analyzed after the adaptation of the rats to the same sensory mismatch condition. The rats were placed on a treadmill on a stage that was translocated in a figure 8-shaped pathway. We recorded HF neuronal activities under three conditions; (1) an initial control session, in which both the stage and the treadmill moved forward, (2) a backward (mismatch) session, in which the stage was translocated backward while the rats locomoted forward on the treadmill, and (3) the second control session. Of the 161 HF neurons, 56 place-differential activities were recorded from the HF CA1 subfield. These place-differential activities were categorized into four types; forward-related, backward-related, both-translocation-related, and session-dependent. Forward-related activities showed predominant spatial firings in the forward sessions, while backward-related activities showed predominant spatial firings in the backward sessions. Both-translocation-related activities showed consistent spatial firings in both the forward and backward conditions. On the other hand, session-dependent activities showed different spatial firings across the sessions. Detailed analyses of the place fields indicated that mean place field sizes were larger in the forward-related, backward-related, and both-translocation-related activities than in the session-dependent activities. Furthermore, firing rate distributions in the place fields were negatively skewed and asymmetric, which is similar to place field changes that occur after repeated experience. These results demonstrate that the HF encodes a naturally impossible new configuration of sensory inputs after adaptation, suggesting that the HF is capable of updating its stored memory to accept a new configuration as a match by repeated experience.
Kin'touch: understanding how visually impaired people explore tactile maps

Tactile or interactive maps are largely used as an orientation aid for visually impaired people. Yet, little is known about haptic exploration strategies and their influence on the resultant cognitive mapping. We have designed a prototype with the potential to automatically analyze different users' exploration strategies. This prototype integrates data from the MS Kinect camera and a multi-touch table. It registers location of hands and digits on a tactile map. Results of preliminary studies show that this approach is promising.
MIMO Precoding Using Rotating Codebooks

Next-generation wireless communications rely on multiple-input-multiple-output (MIMO) techniques to achieve high data rates. Feedback of channel information can be used in MIMO precoding to fully activate the strongest channel modes and improve MIMO performance. Unfortunately, the bandwidth of the control channel by which the feedback is conveyed is severely limited. An important issue is how to improve the MIMO precoding performance with minimal feedback. In this paper, we present a method that uses a rotating codebook technique to effectively improve the precoding performance without the need to increase feedback overhead. The basic idea of the rotating codebook precoding is to expend the effective precoding codebook size via rotating multiple codebooks so that the number of feedback bits remains unchanged. Simulation results are presented to show the performance gain of the proposed rotating codebook precoding over conventional precoding.
PERSONALITY AND SOCIAL PSYCHOLOGY BULLETIN Tropp, Wright / INCLUSION OF INGROUP IN THE SELF Ingroup Identification as the Inclusion of Ingroup in the Self

This article presents a basic conceptualization of ingroup identification as the degree to which the ingroup is included in the self and introduces the Inclusion of Ingroup in the Self (IIS) measure to reflect this conceptualization. Using responses from samples of women and ethnic minority groups, four studies demonstrate the utility of this conceptualization of ingroup identification and provide support for the IIS. Results from these studies establish construct validity, concurrent and discriminant validity, and high degrees of test-retest reliability for the IIS. Reaction time evidence also is provided, supporting the use of the IIS as a measure of ingroup identification. Particular strengths of this conceptualization of ingroup identification and potential uses for the IIS are discussed.
Intractable pain therapy using a new epidural catheter.

Conventional epidural catheters used in performing neurolytic blocks create frequent problems such as kinking, misplacement, and questionable localization of the catheter. We present a study of a new epidural catheter for injection of phenol in patients with severe pain problems. In four of five cases complete pain relief was obtained for several months. The design of this catheter provides improved localization of the injection site. ( JAMA 1982;248:579-581)
Volunteering in dementia care – a Norwegian phenomenological study

Introduction The number of people suffering from dementia will increase dramatically in the future, and this will be a great challenge and concern for health care services. It is assumed that volunteers will strengthen community health care services more in the future than they do today. Aim The aim of this study was to elucidate lived experiences of working as a volunteer in an activity center with adapted activities for home-dwelling people with early stage dementia. Methods Qualitative interviews were implemented in a group of nine female volunteers from an activity center in southern Norway. The interviews were recorded, transcribed verbatim, and analyzed with a descriptive phenomenological method. Results Volunteering in an activity center for home-dwelling people with early stage dementia was reported to provide experiences of being useful and feeling satisfied with performing a good job. It was an advantage for the volunteers to have had experiences from life in general, but also as a health professional or as being the next of kin of a dementia sufferer. It was important for the volunteers to focus on the dementia sufferer and show caring behavior, and interaction with and the appreciation of the health care professionals were also important. The volunteers were motivated by being able to have influence and participate in the planning of the work, to be a part of the social setting, and to learn. However, for some volunteers it was difficult to adjust to an appropriate role. Conclusion In order to promote volunteering in a caring context, mutual trust and freedom should be emphasized. Being conscious of important volunteer characteristics like their experiences, knowledge, and caring behavior, as well as a focus on the staff showing appreciation and providing feedback, may be the difference between success and failure.
Ovarian torsion diagnosed by MRI

An 11-year-old girl was admitted with 3 days of severe lower abdominal pain, on the background of 4 months cyclical abdominal pain. She had some signs of puberty but was not menstruating. She was afebrile and haemodynamically stable. Her abdomen was soft with suprapubic tenderness only. Initial blood tests demonstrated a mild neutrophilia and elevated C-reactive protein. Urine culture was negative. Ultrasonography by the admitting gynaecologist demonstrated a pelvic mass. A magnetic resonance imaging (MRI) scan of her pelvis was performed that day. There was an 864 cm mass lying above the right side of the bladder. It was isointense to muscle on T1 spin echo. It had a low signal intensity periphery with high signal centrally on T2 fast spin echo. Multiple peripheral small oval areas of high T2 signal were seen (Figure 1). There was no enhancement with contrast (Figure 2). A curvilinear structure was seen lying at the right lateral aspect of the mass. The uterus was normal but deviated to the right, the left ovary was unremarkable. A normal right ovary was not identified. Repeat ultrasound with colour Doppler confirmed an avascular oval mass with multiple small cystic structures within the periphery (Figure 3). The patient was taken to theatre for laparotomy with a presumed diagnosis of right ovarian torsion. Operative findings were of a triple twist in the right fallopian tube with an enlarged right ovary. Subsequent pathological examination revealed the ovarian parenchyma to be replaced with haemorrhage and infarcted material in keeping with an ovarian torsion. The fallopian tube was similarly haemorrhagic and infarcted.
Combinatorial Testing for Tree-Structured Test Models with Constraints

In this paper, we develop a combinatorial testing technique for tree-structured test models. First, we generalize our previous test models for combinatorial testing based on AND-XOR trees with constraints limited to a syntactic subset of propositional logic, to allow for constraints in full propositional logic. We prove that the generalized test models are strictly more expressive than the limited ones. Then we develop an algorithm for combinatorial testing for the generalized models, and show its correctness and computational complexity. We apply a tool based on our algorithm to an actual ticket gate system that is used by several large transportation companies in Japan. Experimental results show that our technique outperforms existing techniques.
Enhancing slow wave sleep with sodium oxybate reduces the behavioral and physiological impact of sleep loss.

STUDY OBJECTIVES To investigate whether enhancement of slow wave sleep (SWS) with sodium oxybate reduces the impact of sleep deprivation. DESIGN Double-blind, parallel group, placebo-controlled design SETTING Sleep research laboratory PARTICIPANTS Fifty-eight healthy adults (28 placebo, 30 sodium oxybate), ages 18-50 years. INTERVENTIONS A 5-day protocol included 2 screening/baseline nights and days, 2 sleep deprivation nights, each followed by a 3-h daytime (08:00-11:00) sleep opportunity and a recovery night. Sodium oxybate or placebo was administered prior to each daytime sleep period. Multiple sleep latency test (MSLT), psychomotor vigilance test (PVT), Karolinska Sleepiness Scale (KSS), and Profile of Mood States were administered during waking hours. MEASUREMENTS AND RESULTS During daytime sleep, the sodium oxybate group had more SWS, more EEG spectral power in the 1-9 Hz range, and less REM. Mean MSLT latency was longer for the sodium oxybate group on the night following the first daytime sleep period and on the day following the second day sleep period. Median PVT reaction time was faster in the sodium oxybate group following the second day sleep period. The change from baseline in SWS was positively correlated with the change in MSLT and KSS. During recovery sleep the sodium oxybate group had less TST, SWS, REM, and slow wave activity (SWA) than the placebo group. CONCLUSIONS Pharmacological enhancement of SWS with sodium oxybate resulted in a reduced response to sleep loss on measures of alertness and attention. In addition, SWS enhancement during sleep restriction appears to result in a reduced homeostatic response to sleep loss.
Cargo Capacity Management with Allotments and Spot Market Demand

We consider a problem faced by an airline that operates a number of parallel flights to transport cargo between a particular origin to destination pair. The airline can sell its cargo capacity either through allotment contracts or on the spot market, where customers exhibit choice behavior between different flights. The goal is to simultaneously select allotment contracts among available bids and find a booking control policy for the spot market to maximize the sum of the profit from the allotments and the total expected profit from the spot market. We formulate the booking control problem on the spot market as a dynamic program and construct approximations to its value functions, which can be used to estimate the total expected profit from the spot market. We show that our value function approximations provide upper bounds on the optimal total expected profit from the spot market, and they allow us to solve the allotment selection problem through a sequence of linear mixed-integer programs with a special structure. Furthermore, the value function approximations are useful for constructing a booking control policy for the spot market with desirable monotonic properties. Computational experiments show that the proposed approach can be scaled to realistic problems and provides well-performing allotment allocation and booking control decisions.
Fossil Dolphin Otekaikea marplesi (Latest Oligocene, New Zealand) Expands the Morphological and Taxonomic Diversity of Oligocene Cetaceans

The Oligocene Epoch was a time of major radiation of the Odontoceti (echolocating toothed whales, dolphins). Fossils reveal many odontocete lineages and considerable structural diversity, but whether the clades include some crown taxa or only archaic groups is contentious. The New Zealand fossil dolphin “Prosqualodon” marplesi (latest Oligocene, ≥23.9 Ma) is here identified as a crown odontocete that represents a new genus, Otekaikea, and adds to the generic diversity of Oligocene odontocetes. Otekaikea marplesi is known only from the holotype, which comprises a partial skeleton from the marine Otekaike Limestone of the Waitaki Valley. Otekaikea marplesi was about 2.5 m long; it had procumbent anterior teeth, and a broad dished face for the nasofacial muscles implicated in production of echolocation sounds. The prominent condyles and unfused cervical vertebrae suggest a flexible neck. A phylogenetic analysis based on morphological features places Otekaikea marplesi in the extinct group Waipatiidae, within the clade Platanistoidea. The phylogeny implies an Oligocene origin for the lineage now represented by the endangered Ganges River dolphin (Platanista gangetica), supporting an Oligocene history for the crown Odontoceti.
Functional binding interaction identified between the axonal CAM L1 and members of the ERM family

Ayeast two-hybrid library was screened using the cytoplasmic domain of the axonal cell adhesion molecule L1 to identify binding partners that may be involved in the regulation of L1 function. The intracellular domain of L1 bound to ezrin, a member of the ezrin, radixin, and moesin (ERM) family of membrane–cytoskeleton linking proteins, at a site overlapping that for AP2, a clathrin adaptor. Binding of bacterial fusion proteins confirmed this interaction. To determine whether ERM proteins interact with L1 in vivo, extracellular antibodies to L1 were used to force cluster the protein on cultured hippocampal neurons and PC12 cells, which were then immunolabeled for ERM proteins. Confocal analysis revealed a precise pattern of codistribution between ERMs and L1 clusters in axons and PC12 neurites, whereas ERMs in dendrites and spectrin labeling remained evenly distributed. Transfection of hippocampal neurons grown on an L1 substrate with a dominant negative ERM construct resulted in extensive and abnormal elaboration of membrane protrusions and an increase in axon branching, highlighting the importance of the ERM–actin interaction in axon development. Together, our data indicate that L1 binds directly to members of the ERM family and suggest this association may coordinate aspects of axonal morphogenesis.
Cyber Bullying: Overview and Strategies for School Counsellors, Guidance Officers, and All School Personnel

Abstract Cyber bullying or bullying via information and communications technology tools such as the internet and mobile phones is a problem of growing concern with school-aged students. Cyber bullying actions may not take place on school premises, but detrimental effects are experienced by victims of cyber bullying in schools. Tools used by cyber bullies are presented and the impact on victims is discussed. Intervention strategies for school counsellors, guidance officers, and school personnel to adopt with students and parents are presented.
Understanding the utilisation of Information Systems Evaluation: Four Case studies

The aim of this study is to explore and investigate the use of Information System (IS) evaluation in practice. Given that evaluation use is not a well-studied topic in IS research, we first propose a theoretical framework based on literature review, to guide our understanding of relevant issues. This framework identifies three important dimensions in related to IS evaluation: IS evaluation, Stakeholder involvement and Evaluation use. These dimensions are examined in four IS projects in China. In total, 37 interviews have been conducted and data are analysed using Leximancer qualitative data analysis software. Results are organised based on the proposed framework. The results suggest that both the evaluation process and the output from IS evaluation can be used instrumentally, conceptually and symbolically by different stakeholders. A list of such uses are generated in each case, with concepts identified by Leximancer. The cases demonstrate the applicability of the proposed framework and areas for further development are identified.
Distortion in Pulse-Duration Modulation

Pulse-duration modulation inherently gives rise to a certain amount of audio distortion. The analysis presented in this paper relates the distortion to system parameters. The method of analysis is exact, and therefore correct for any degree of modulation. It does not, however, lend itself to periodic sampling. The results are applied to three specific cases.
A novel adaptive approach to the restoration of digital images corrupted by salt & pepper impulse noise

The paper proposes a new adaptive 2D spatial filter operator for the restoration of salt & pepper impulse corrupted digital images. The Adaptive Impulse Filter effectively identifies the impulsive positions of the noisy digital image and switches to restore them by an adaptive impulse correction scheme. Experimental results in terms of objective metrics and visual analysis through varied impulse noise levels favor the new algorithm when compared to most other impulse filters. The efficient impulse filter gives better signal preservation and provides quality results devoid of impulsive patches with less computational complexity even at very high levels of impulse noise.
Nineteen Baculovirus Open Reading Frames, Including LEF-12, Support Late Gene Expression

ABSTRACT A set of 18 plasmid subclones of the Autographa californica nuclear polyhedrosis virus genome, each containing an identified late expression factor gene (lef), supports expression from a late viral promoter in transient expression assays in the SF-21 cell line derived fromSpodoptera frugiperda. We have constructed a further set of plasmids in which each lef open reading frame (ORF) is controlled by the Drosophila melanogasterheat shock protein 70 (hsp70) promoter and epitope tagged. Failure of this set of plasmids to support transient late gene expression, and the inability of the p47 ORF to replace thep47-containing plasmid supplied in the lefplasmid library, led to the identification of a 19th late expression factor gene (lef-12) located adjacent to thep47 gene. The sequence of lef-12 is predicted to encode a protein of 21 kDa with no homology to any previously identified protein. The set of 19 hsp70-controlled lef ORFs (HSEpiHis lef library) supports transient expression from a late viral promoter. lef-12 did not affect expression from an early baculovirus promoter. In TN-368 cells, which are also permissive for virus replication, lef-12 provided a stimulatory effect but did not appear to be essential.
