Does Attachment to Parents Mediate the Relationship Between Couple Conflict and Adolescent Self-Regulation?

Does Attachment to Parents Mediate the Relationship Between Couple Conflict and Adolescent Self-Regulation? Lisa Tensmeyer Hansen School of Family Life, BYU Master of Science Adolescent self-regulation follows a developmental trajectory over time with ups and downs during maturation. This paper uses growth curve analysis to look at change in selfregulation over time. Although self-regulation scores may increase during latency, adolescents differ in levels of self-regulation due to biological and socialization factors. In addition, exposure to couple conflict has been shown to affect levels of self-regulation. The current study examined the role of attachment to parents as a mediator between couple conflict and adolescent self-regulation outcomes, controlling for gender of child. Participants were 681families with a child between the ages of 11 and 13 at time 1 (M age of child at time 1 = 11.33, S.D. = 1.02, 47.9% female) who took part in the Flourishing Families survey at times 1, 2, 3, & 4. Structural equation modeling confirmed that self-regulation was negatively related to couple conflict overall, although self-regulation in the group of adolescents experiencing the lowest level of conflict increased as couple conflict increased. Self-regulation was also positively related to attachment to father (but not to mother), while gender of adolescent was not significantly related to self-regulation or attachment. There was also evidence that father attachment partially mediated the relationship between couple conflict and adolescent self-regulation outcomes. The discussion focuses on the importance of continued research examining the mechanisms through which the father attachment bond influences the development of adolescent self-regulation.
Cooperative multi-robot box-pushing

This paper deals with the communication in task-sharing between two autonomous six-legged robots equipped with object and goal sensing, and a repertoire of contact and light-following behaviors. The performance of pushing an elongated box towards a goal region is difficult for a single robot and improves significantly when performed cooperatively, but requires careful coordination between the robots. We present and experimentally demonstrate an approach that utilizes cooperation at three levels: sensing, action, and control, and takes the advantage of a simple communication protocol to compensate for the robots' noisy and uncertain sensing.
Growth, Yield and Yield Components of American Cotton (Gossypium hirsutum L.) As Affected by Cultivars and Nitrogen Fertilizer

Nitrogen stress in upland cotton addresses significant and visible shortfalls in plant growth. It is an important element both in nature and agricultural conditions, for cotton plant growth and development. To evaluate the response of different yield and yield component of high yielding upland cotton cultivars to various split applications of nitrogen fertilizer, a two season field research was conducted during 2007 and 2008. Different experimental treatments were comprised on cotton leaf curl virus (CLCV) resistant high yielding cotton cultivars i.e. CIM-496, CIM-506, CIM-534 along with different nitrogen rate of Zero, 60, 110 and 160 kg ha -1 . However, cultivar CIM-534 produced significantly the highest plants, nodes per plant and flowering buds plant -1 . While, CIM-496 showed better potential in relation to leaf area index, crop growth rate, relative growth rate and net assimilation rate (physiological), dry biomass and number of bolls m -2 (reproductive) and seed cotton, cotton seed (yield) parameters during both the seasons. On increasing N rates, vegetative characteristics of cotton like plant height, nodes plant -1 and number of flowering buds per plant significantly gave better response with each cultivar. Advanced cotton cultivars produced significantly higher total dry biomass (TDM), bolls m -2 , seed cotton, cotton seed and GOT % age on each increment in applied nitrogen. The nitrogen fertilizer rate i.e. 160 kg ha -1 proved to be the optimum for the highest cotton yield and yield components. Further fibre characteristics such as staple length, uniformity ratio and maturity ratio significantly influenced by different cultivars.
Stress in Pregnancy: A Role for Neuroactive Steroids in Protecting the Fetal and Neonatal Brain

Stressors during pregnancy can lead to perinatal brain injury resulting in serious neurological impairment. Neuroactive steroid concentrations are elevated during pregnancy and are remarkably high in the fetal brain. In long-gestation species, including humans, these steroids enhance GABAergic inhibition and reduce the possibility of cerebral excitotoxicity during the last third of gestation. The fetal brain responds to acute hypoxia/ischemia by increasing steroid concentrations further as protection against excitotoxic cell death. The placenta has a key role in maintaining neuroactive steroid concentrations in the brain by acting as a source of precursors for neuroactive steroid synthesis. Gestational neuroactive steroid concentrations are needed for normal cell proliferation and cell death in the late gestation brain and a loss of these steroids at preterm birth may adversely affect development and vulnerability to injury.
SHiP: Signature-based Hit Predictor for high performance caching

The shared last-level caches in CMPs play an important role in improving application performance and reducing off-chip memory bandwidth requirements. In order to use LLCs more efficiently, recent research has shown that changing the re-reference prediction on cache insertions and cache hits can significantly improve cache performance. A fundamental challenge, however, is how to best predict the re-reference pattern of an incoming cache line. This paper shows that cache performance can be improved by correlating the re-reference behavior of a cache line with a unique signature. We investigate the use of memory region, program counter, and instruction sequence history based signatures. We also propose a novel Signature-based Hit Predictor (SHiP) to learn the re-reference behavior of cache lines belonging to each signature. Overall, we find that SHiP offers substantial improvements over the baseline LRU replacement and state-of-the-art replacement policy proposals. On average, SHiP improves sequential and multiprogrammed application performance by roughly 10% and 12% over LRU replacement, respectively. Compared to recent replacement policy proposals such as Seg-LRU and SDBP, SHiP nearly doubles the performance gains while requiring less hardware overhead.
Hormonal and genetic modulation of memory processes in healthy humans: focus on cortisol and "HDAC5"

Individual differences in memory performance can be due to the influence of various hormones as well as genetic variations and epigenetic modifications. These complex molecular and genetic mechanisms can impact learning, memory consolidation and retrieval differentially. This thesis deals with the modulation of memory processes in healthy human subjects focusing on two viewpoints. Firstly, by addressing the influence of the stress hormone cortisol, as evidence from animal and human studies shows that cortisol can enhance memory consolidation and impair retrieval. Secondly, by analyzing genetic and epigenetic data to find a target associated with synaptic plasticity and memory formation. To investigate if stress, induced by the cold pressor test, affects memory processes, a fear-conditioning paradigm was used. The stress group showed an increase in the cortisol level and reduced retrieval of the conditioned fear memory. In a further study, we investigated if inter-individual changes in basal cortisol levels affect episodic memory. Results showed an association between stronger decreases in cortisol levels during retrieval and a better recall performance. In a large genetic study we focused on genetic polymorphisms tagging histone deacetylase 5 (HDAC5), a gene associated with synaptic plasticity and memory formation in animal models. We detected significant associations between these polymorphisms and episodic memory performance, especially for emotional information. Surprisingly, these polymorphisms were strongly associated with expression levels of a transcript in the vicinity of HDAC5. These results may have implications for the understanding of the mechanisms underlying memory formation in healthy subjects and the interpretation of genetic data. Additionally, our results may have clinical implications for different neuropsychiatric disorders, such as depression, anxiety disorders or posttraumatic stress disorder, for which learning and memory play an important role.
Muscle Strength and Speed Performance in Youth Soccer Players

Abstract This study aimed to examine the relationship between maximum leg extension strength and sprinting performance in youth elite male soccer players. Sixty-three youth players (12.5 ± 1.3 years) performed 5 m, flying 15 m and 20 m sprint tests and a zigzag agility test on a grass field using timing gates. Two days later, subjects performed a one-repetition maximum leg extension test (79.3 ± 26.9 kg). Weak to strong correlations were found between leg extension strength and the time to perform 5 m (r = -0.39, p = 0.001), flying 15 m (r = -0.72, p < 0.001) and 20 m (r = -0.67, p < 0.001) sprints; between body mass and 5 m (r = -0.43, p < 0.001), flying 15 m (r = -0.75, p < 0.001), 20 m (r = -0.65, p < 0.001) sprints and agility (r =-0.29, p < 0.001); and between height and 5 m (r = -0.33, p < 0.01) and flying 15 m (r = -0.74, p < 0.001) sprints. Our results show that leg muscle strength and anthropometric variables strongly correlate with sprinting ability. This suggests that anthropometric characteristics should be considered to compare among youth players, and that youth players should undergo strength training to improve running speed.
The hard X-ray spectrum of the Seyfert galaxy IRAS 18325–5926: reflection from an ionized disc and variable iron K emission

We report our analysis of the X-ray spectra of the Seyfert galaxy IRAS 18325-5926 (= Fairall 49) obtained from various X-ray observatories prior to XMM-Newton, including new results from two RXTE and one BeppoSAX observations. A relatively steep continuum slope (Γ ≃ 2.2) in the 2-15 keV band is confirmed. The continuum spectrum observed with the BeppoSAX PDS shows a possible roll-over at energies above 30 keV, indicating a Comptonizing corona cooler than in other Seyfert nuclei. The X-ray spectrum above 2 keV is best explained with a model including reflection from a highly ionized disc with significant relativistic blurring. The iron Ka emission feature is then mainly due to Fe XXV. The seven recent observations show that the iron K emission flux appears to follow the continuum between the observations separated by a few months to years, although some exceptions suggest that the linestrength may be determined in a more complex way.
Aminoglycoside Efflux in Pseudomonas aeruginosa: Involvement of Novel Outer Membrane Proteins

ABSTRACT The expression of tripartite multidrug efflux pumps such as MexA-MexB-OprM in Pseudomonas aeruginosa contributes to intrinsic resistance to a wide variety of antimicrobials, including β-lactams, chloramphenicol, macrolides, quinolones, and tetracycline. The MexX-MexY linker-pump combination has been shown to be involved in intrinsic resistance to aminoglycosides, but the identity of the cognate outer membrane channel component remains under debate. Fourteen uncharacterized OprM homologs identified in the genome of P. aeruginosa were examined as candidates for this role by assessing the minimum inhibitory concentrations (MICs) of aminoglycosides in P. aeruginosa strain PAK knockout mutants lacking the corresponding genes. Insertional inactivation of OpmG, OpmI, and OpmH resulted in decreases of various degrees in the MICs of streptomycin, kanamycin, and gentamicin. When reintroduced into P. aeruginosa on multicopy plasmids, OpmG was able to complement the susceptibility of an opmG::miniTn5 mutant; however, cloned opmH, the proposed ortholog of Escherichia coli tolC according to our phylogenetic analysis, was able to only partially complement the opmH::miniTn5 mutant. Mini-microarray hybridization analysis demonstrated that opmG disruption does not affect expression of OpmI or OpmH (ruling out such indirect effects on aminoglycoside resistance); however, opmH disruption did have possible effects on expression of OpmG and OpmI. Based on the data, we propose that OpmG is a major outer membrane efflux channel involved in aminoglycoside efflux in P. aeruginosa PAK and that OpmI, its most related paralog, may share an overlapping function.
FTIR spectroscopic studies on aggregation process of the β‐amyloid 11–28 fragment and its variants

Aggregation of Aβ peptides is a seminal event in Alzheimer's disease. Detailed understanding of the Aβ assembly process would facilitate the targeting and design of fibrillogenesis inhibitors. Here, conformational studies using FTIR spectroscopy are presented. As a model peptide, the 11–28 fragment of Aβ was used. This model peptide is known to contain the core region responsible for Aβ aggregation. The structural behavior of the peptide during aggregation provoked by the addition of water to Aβ(11–28) solution in hexafluoroisopropanol was compared with the properties of its variants corresponding to natural, clinically relevant mutants at positions 21–23 (A21G, E22K, E22G, E22Q and D23N). The results showed that the aggregation of the peptides proceeds via a helical intermediate, and it is possible that the formation of α‐helical structures is preceded by creation of 310‐helix/310‐turn structures.

The Psychosocial Impact of Closed-Circuit Televisions on Persons with Age-Related Macular Degeneration

Closed-circuit televisions (CCTVs) are used by many elderly people who have age-related macular degeneration (AMD). The functional vision of 68 participants, which was measured immediately after they adopted CCTVs, suggested successful outcomes, but the psychosocial impact of the use of CCTVs did not peak until a month later. The findings help identify circumstances in which CCTV-assisted rehabilitation may be enhanced for better long-term outcomes.
Evaluation of transport and storage techniques for isolation of Campylobacter fetus subsp. jejuni from turkey cecal specimens

Immediate culturing of fecal specimens is not always possible, and appropriate methods for transport and storage of Campylobacter fetus subsp. jejuni specimens have not been fully evaluated. Using nine techniques, we studied the survival of C. fetus subsp. jejuni in cecal specimens from infected turkeys. The organisms survived in specimens held without transport medium for 3 to 15 days (median, 9 days) at 4 degrees C, and 2 to 9 days (median, 4 days) at 25 degrees C. Only 20% of specimens frozen for 24 h at either -20 or -70 degrees C yielded C. fetus subsp. jejuni. Specimens dried on filter paper strips were negative for C. fetus subsp. jejuni within 1.5 h. Cary-Blair medium with decreased agar was the best of the six transport media tested, it enabled recovery of the organism from 100% (3 days) and 71% (7 days) of cecal samples held at 4 degrees C and 94% (3 days) and 85% (7 days) of cecal specimens held at 25 degrees C. In contrast, more than half of all cecal specimens held at 4 or 25 degrees C in Culturettes or buffered glycerol saline were negative by 3 days, and all were negative at 7 days. Results with the other three media studied (Campy-thio, thioglycolate medium, and alkaline peptone water) were intermediate. Overnight incubation of specimens in alkaline peptone water at 37 or 42 degrees C did not enhance recovery of C. fetus subsp. jejuni. Therefore, refrigeration without a transport medium is satisfactory for up to 3 days for recovery of C. fetus subsp. jejuni from specimens, however, we recommend the use of Cary-Blair medium with decreased agar for specimens that must be transported or stored for longer than 3 days and for rectal swabs, to prevent drying.
Women and Spirituality

Written by an acclaimed scholar to enrich and complete the vision offered by traditional Western spirituality, Women and Spirituality demonstrates that women, as women, have a valuable contribution to make to religion. This new edition is revised and updated in light of thirteen years of feminism, including new biblical role models and a new chapter on women's special relationship to time. Prodding readers to pay attention to their own experiences, Ochs challenges traditional religious concepts such as solitary struggle, otherworldliness, and the spiritual journey to a distant goal, and shows how women's spirituality focuses on relationships with others, commitment to this world, and engagement with the present.
Working With Rather Than Against Macaques During Blood Collection

Training macaques to cooperate during blood collection is a practicable and safe alternative to the traditional procedure implying forced restraint. It takes a cumulative total of about 1 hr to train an adult female or adult male rhesus macaque successfully to present a leg voluntarily and accept venipuncture in the homecage. Cooperative animals do not show the significant cortisol response and defensive reactions that typically occur in animals who are forcibly restrained during this common procedure.
Contextual Modulation of Physiological and Psychological Responses Triggered by Emotional Stimuli

A series of emotional events successively occur in temporal context. The present study investigated how physiological and psychological responses are modulated by emotional context. Skin conductance response (SCR), heart rate, corrugator activity, zygomatic activity, and subjective feelings during emotional picture viewing were measured. To create an emotional context, a unpleasant or pleasant picture was preceded by three types of pictures, i.e., unpleasant, pleasant, and neutral pictures, resulting in six pairings. The results showed that viewing an unpleasant picture attenuated pleasant feelings induced by the following pleasant picture. On the other hand, preceding pleasant pictures decreased SCR to the following pictures. The effects of contextual modulation on emotional responses might be due to the informative function of pre-existing feelings; unpleasant feelings signal a threatening environment, whereas pleasant feelings signal a benign environment. With respect to facial muscle activities, viewing a pleasant picture decreased corrugator activity in response to the preceding picture. These findings suggest several types of contextual modulation effects on psychological, autonomic, and somatic responses to emotional stimuli.
Crecimiento económico en Colombia: una aproximación empírica fundamentada en la perspectiva capital humano (1960-2009)

The aim of this paper is to specify an empirical model based on theoretical arguments, quantifying the influence of human capital, measured through a set of variables that reflect the health and education behavior on the outcome of economic growth observed for Colombia, between 1960 and 2009. The authors review the literature on economic growth and human capital, represented by health and education, so that, with the sources of information available in Colombia, they do a selection of data that allows the collection of variables that reflect and quantify the transmission channels suggested by existing theory. Finally, they specify an empirical model that estimates the theoretical relationship between human capital and economic growth.
Insulin Resistance Is Associated With Reduced Mitochondrial Oxidative Capacity Measured by 31P-Magnetic Resonance Spectroscopy in Participants Without Diabetes From the Baltimore Longitudinal Study of Aging

Whether individuals with insulin resistance (IR) but without criteria for diabetes exhibit reduced mitochondrial oxidative capacity is unclear; addressing this question could guide research for new therapeutics. We investigated 248 participants without diabetes from the Baltimore Longitudinal Study of Aging (BLSA) to determine whether impaired mitochondrial capacity is associated with prediabetes, IR, and duration and severity of hyperglycemia exposure. Mitochondrial capacity was assessed as the postexercise phosphocreatine recovery time constant (τPCr) by 31P-magnetic resonance spectroscopy, with higher τPCr values reflecting reduced capacity. Prediabetes was defined using the American Diabetes Association criteria from fasting and 2-h glucose measurements. IR and sensitivity were calculated using HOMA-IR and Matsuda indices. The duration and severity of hyperglycemia exposure were estimated as the number of years from prediabetes onset and the average oral glucose tolerance test (OGTT) 2-h glucose measurement over previous BLSA visits. Covariates included age, sex, body composition, physical activity, and other confounders. Higher likelihood of prediabetes, higher HOMA-IR, and lower Matsuda index were associated with longer τPCr. Among 205 participants with previous OGTT data, greater severity and longer duration of hyperglycemia were independently associated with longer τPC. In conclusion, in individuals without diabetes a more impaired mitochondrial capacity is associated with greater IR and a higher likelihood of prediabetes.

Cyclooxygenase‐2 inhibitory and antioxidant compounds from the truffle Elaphomyces granulatus

The ethanol extract of fruiting bodies of Elaphomyces granulatus, a truffle‐like fungus, was evaluated for cyclooxygenase‐2 (COX‐2) enzyme inhibitory and antioxidant activities. Inhibition of COX‐2 activity was evaluated in mouse macrophages (RAW 264.7). The extract of E. granulatus caused a 68% inhibition of COX‐2 activity at 50 µg/mL. Bioassay‐guided investigation led to the isolation and identification of two active compounds, syringaldehyde and syringic acid. Syringaldehyde moderately inhibited COX‐2 activity with an IC50 of 3.5 µg/mL, while syringic acid strongly inhibited COX‐2 activity with an IC50 of 0.4 µg/mL. The antioxidant activity of the extract and isolated compounds was evaluated in HL‐60 cells by the DCFH‐DA method. The extract of E. granulatus showed a potent antioxidant effect, with an IC50 of 41 µg/mL. Of the pure compounds, syringic acid displayed a strong antioxidant activity, with an IC50 of 0.7 µg/mL, while syringaldehyde showed no activity in the assay. Copyright © 2008 John Wiley & Sons, Ltd.
