Linking adolescent family and peer relationships to the quality of young adult romantic relationships: The mediating role of conflict tactics

This study examined the associations between the quality of adolescents' peer and family relationships and the quality of their young adult romantic relationships. Adolescents (N = 253) completed self-report measures of their family and peer relationships in grades 10–12; 7 years later, they reported on connectedness, discord, and the conflict tactics used by both partners in their current romantic relationships. Family relationship quality in adolescence predicted the levels of connectedness, discord, and specific conflict behaviors youth reported in their adult romantic relationships. The use of discussion to resolve conflict mediated the association between adolescent family relationships and the level of connectedness in adult romantic relationships. Moreover, use of discussion and physical conflict/threat each partially mediated the effect of family relationship quality on romantic discord. Possible mechanisms linking family of origin relationships to adult romantic relationships are discussed.
A study of molecular vibrational relaxation mechanism in condensed phase based upon mixed quantum-classical molecular dynamics. I. A test of IBC model for the relaxation of a nonpolar solute in nonpolar solvent at high density.

In order to investigate vibrational relaxation mechanism in condensed phase, a series of mixed quantum-classical molecular dynamics calculations have been executed for nonpolar solute in nonpolar solvent and polar solute in polar solvent. In the first paper (Paper I), relaxation mechanism of I2 in Ar, where Lennard-Jones force is predominant in the interaction, is investigated as a function of density and temperature, focusing our attention on the isolated binary collision (IBC) model. The model was originally established for the relaxation in gas phase. A key question, here, is "can we apply the IBC model to the relaxation in the high-density fluid? " Analyzing the trajectory of solvent molecule as well as its interaction with the solute, we found that collisions between them may be defined clearly even in the high-density fluid. Change of the survival probability of the vibrationally first excited state on collision was traced. The change caused by collisions with a particular solvent molecule was also traced together with the interaction between them. Each collision makes a contribution to the relaxation by a stepwise change in the probability. The analysis clearly shows that the relaxation is caused by collisions even in the high-density fluid. The difference between stepwise relaxation and the continuous one found for the total relaxation in the low-density fluid and in the high-density one, respectively, was clarified to come from just the difference in frequency of the collision. The stronger the intensity of the collision is, the greater the relaxation caused by the collision is. Further, the shorter the collision time is, the greater the resultant relaxation is. The discussion is followed by the succeeding paper (Paper II), where we report that molecular mechanism of the relaxation of a polar molecule in supercritical water is significantly different from that assumed in the IBC model despite that the density dependence of the relaxation rate showed a linear correlation with the local density of water around the solute, the linear correlation being apparently in good accordance with the IBC model. The puzzle will be solved in Paper II.
The challenges of ITIL implementations

Originating from the UK, the IT Infrastructure Library (ITIL) is an IT Service Management framework whose adoption is rapidly spreading throughout Canada, Netherlands, South Africa, India, USA, and Australia. Promoted as a collection of "Best Practices" in IT service management, ITIL is gaining a reputation as a "silver bullet" to IT Service Management woes and is now . gaining popularity amongst IT vendors and leaders of best practices worldwide. Increased IT productivity, IT accountability, increased compliance and reduced IT costs, are just some of the promised list of benefits. More and more organisations are plam1ing to embark on ITIL implementations as organisations and research groups begin to document ! TIL's benefits. As with any large IT project implementation or continuous improvement program undertaking, organisations may find that unexpected challenges arise and changes are required. This research will focus on the challenges organisations face during implementation, and will provide some insight into the continuous process of implementing ITIL. As the demand and awareness for ITIL increases, so too does the need for better understanding of organisation culture, catalysts and other changes that are needed to support the ITIL implementation process.
Motor Imagery, Physical Practice, and Memory: The Effects on Performance and Workload

The theoretical explanations used to explain changes in performance during motor imagery and physical practice conditions are inconsistent when memory retrieval is and is not required. This study measured performance time and workload during acquisition, a retention test requiring memory retrieval, and a retention test not requiring memory retrieval using a key-pressing task. The participants were assigned to physical practice with or without instructions to learn or motor imagery with or without instructions to learn. A diagram of the keys was presented during the practice trials and the first retention test, but was not presented during the second test. The results revealed no effect for the learning instructions or performance changes during the practice phases. However, during both retention tests participants in the physical practice conditions performed significantly faster than those in the motor imagery conditions. Also, higher levels of workload were reported for the motor imagery conditions when the retention test required memory retrieval compared to the other phases. A discussion of the implications of workload on performance is presented with respect to varying practice conditions.
Effect of packed red blood cells transfusion on plasma fibronectin during liver resection

summary Our study aimed at evaluating the effect of blood transfusion – allogeneic or autologous – on plasma levels of fibronectin during liver resections. Thirty‐five patients scheduled for liver resection were randomly allocated to receive autologous (group autologous blood transfusion (ABT), n= 19) or allogeneic (homologous) (homologous blood transfusion (HBT), n= 16) packed red blood cell to maintain serum haemoglobin concentration above 9 g. Serum levels of fibronectin were measured before induction of anaesthesia, at the end of operation and at first, third and sixth postoperative day. Perioperative morbidity and survival rate were also recorded. Serum fibronectin levels were significantly higher (P < 0·05) in the autologous group than in the allogeneic, at the first (134 ± 49 μg mL−1 vs. 89 ± 31 μg mL−1) and third (178 ± 51 μg mL−1 vs. 96 ± 41 μg mL−1) postoperative day. No differences in survival and complication rate between the two groups were observed. Concentrations of serum fibronectin seem to be adversely affected by allogeneic blood transfusion during liver resection surgery, although this does not seem to affect patients’ morbidity and mortality.
Impact of Workers' Remittances on Financial Development in Nigeria

In this study we examine the nexus between remittances and financial development (FINDEV) in Nigeria from 1977 to 2009. Towards achieving the objective of this study, we employ both the ordinary least square estimation (OLSE) technique and the Generalized Method of Moments (GMM) estimator. Moreover, key diagnostic tests are carried out in order to ascertain model adequacy. We also use two indicators of FINDEV, namely: the ratio of money supply to GDP (m2/gdp) and the ratio of private credit to GDP (cps/gdp). The results generally indicate that remittances positively and significantly influence financial development in Nigeria, with the exception of the cps/gdp measure of FINDEV in the GMM estimation where the coefficient is insignificant. This implies that remittances augment liquid liabilities more than loanable funds in Nigeria, as remittances are likely used more for consumption purposes than for productive ventures in the country. Since remittances provide foreign exchange that is vital to both the internal and the external sectors of the economy, they should be encouraged via appropriate policy formulation and implementation. Financial intermediaries and institutions operating in Nigerian should also intensify the mobilization of remittances with the aim of making them important sources of loanable funds in the country.
INFERENCE ON SOCIAL EFFECTS WHEN THE NETWORK IS UNKNOWN USING CONVEX OR LINEAR PROGRAMMING

The paper considers panel data models with social interactions when the network is unobserved and there are endogenous and exogenous social effects. The system of equations is estimated jointly by a convex program. The method does not require the knowledge of the variances of the errors nor a subgaussian assumption. It is possible to incorporate linear and sign restrictions and to impose that the matrices of endogenous and exogenous social effects have same nonzeros. The confidence sets are obtained by solving convex programs. Because the network is unknown, it is not known which exogenous variable does not have a direct effect and can be a valid excluded instrument for the endogenous variables having a direct effect. Therefore we extend the framework of Gautier and Tsybakov (2011, 2014) which handles unknown exclusion restrictions to systems of simultaneous equations. The confidence sets are robust to identification and can be infinite when there is not enough sparsity/exclusion restrictions, when, for some included endogenous regressor, all instruments are too weak or when the number of time periods is too small. The second half of the paper presents an alternative approach that only relies on linear programming. This is numerically very attractive for the study of large networks.
Yeast Nuclear Extract Contains Two Major Forms of RNA Polymerase II Mediator Complexes*

The yeast Mediator complex is required for transcription by RNA polymerase II (pol II) in vivo andin vitro. This complex of over 20 polypeptides associates with pol II and is recruited to transcription complexes at promoters. Previous isolations of yeast Mediator-containing complexes in different laboratories have identified several distinct complexes. To identify the major forms of Mediator in yeast, Mediator was isolated from nuclear extracts using a two-step chromatographic procedure, avoiding ion exchange chromatography and high salt conditions to prevent dissociation of subunits during purification. Components of the Mediator complexes were identified by mass spectrometry and Western analysis. The major form of Mediator, termed pol II·Med, contained pol II and Mediator, including the Srb8–11 module. A second lower molecular size complex was also identified, termed Mediator core (Medc), which lacked pol II, Srb8–11, Rox3, Nut1, and the Rgr1 module. Both of these complexes were active in transcription in vitro, although the Medc complex had significantly lower activity and could compete with the activity of the pol II·Med complexin vitro.
Domains of U4 and U6 snRNAs required for snRNP assembly and splicing complementation in Xenopus oocytes.

Structure‐function relationships in the vertebrate U4‐U6 snRNP have been analysed by assaying the ability of mutant RNAs to form U4‐U6 snRNPs and to function in splicing complementation in Xenopus oocytes. The mutants define three categories of domain within the RNAs. First, domains which are not essential for splicing. These include regions of U6 which have previously been implicated in the capping and transport to the nucleus of U6 RNA as well as, less surprisingly, regions of U4 and U6 which have been poorly conserved in evolution. Second, domains whose mutation reduces U4‐U6 snRNP assembly or stability. This group includes mutations in both the proposed U4‐U6 interaction domain, and also, in the case of U6, in a highly conserve sequence flanking stem I of the interaction domain. These mutants are all defective in splicing. Third, regions not required for U4‐U6 assembly, but required for splicing complementation. This category defines domains which are likely to be required for specific contacts with other components of the splicing machinery. Combinations of mutants in the U4 and U6 interaction domain are used to show that there are not only requirements for base complementarity but also for specific sequences in these regions.
Seekers and avoiders: Using health information orientation to explore audience segmentation

Abstract Differentiation of health communication strategies can address a new type of health disparity, a communication inequity. This exploratory study collected survey data to identify online health information audience groups based on health information orientation and objective and perceived health literacy. Two groups were identified and compared showing that health information orientation could be used for systematic segmentation of the consumers of online health information. The two distinct information behaviors, health information engagement and health information apprehension, provided a stable foundation for audience segmentation. The paper discusses how the segmentation of audiences based on the reported information behaviors and information orientation can facilitate the development of targeted health communication and information engagement approaches.
INFORMATION SHARING AND PRIVACY PRACTICES IN ONLINE SOCIAL NETWORKS

This thesis presents a study on privacy attitudes and concerns on Facebook, focusing on the practice of information sharing and exploring the concept of narrowcasting the content shared. The study borrows a methodology from previous research where both qualitative and quantitative data are gathered in order to test a collection of hypotheses. Drawing from the analysis of questionnaire and data fetched from Facebook’s API we verify and discuss the proposed hypotheses and derive a set of guidelines and principles to aid the design process of a privacy-sensitive information sharing mechanism.
Twitter user growth analysis based on diversities in posting activities

Purpose The purpose of this paper is to clarify the characteristics of growth users over a long time to strategically collect a large amount of specific users’ tweets. Twitter reflects events and trends in users’ real lives because many of them post tweets related to their experiences. Many studies have succeeded in detecting events along with real-life information from a large amount of tweets by assuming users as social sensors. To collect a large amount of tweets based on specific users for successful Twitter studies, the authors have to know the characteristics of users who are active over long periods of time. Design/methodology/approach The authors explore the status of users who were active in 2012, and classify users into three statuses of Dead, Lock and Alive. Based on the differences between the numbers of tweets in 2012 and 2016, the authors further classify Alive users into three types of Eraser, Slumber and Growth. The authors analyze the characteristic feature values observed in each user behavior and provide interesting findings with each status/type based on Gaussian mixture model clustering and point-wise mutual information. Findings From their sophisticated experimental evaluations, the authors found that active users more easily dropped out than inactive users, and users who engaged in reciprocal communications often became Growth type. Also, the authors found that active users and users who were not retweeted by other users often became Eraser type. The authors’ proposed methods effectively predicted Growth/Eraser-type users compared with the logistic regression model. From these results, the authors clarified the effectiveness of five feature values per active hour to detect intended Twitter user growth for strategically collecting a large amount of tweets. Originality/value The authors focus on user growth prediction. To appropriately estimate users who have potential for growth, they collect a large amount of users and explore their status and growth after three years. The research quantitatively clarifies the characteristics of growth users by clustering using robust feature values and provides interesting findings obtained by analysis. After that, the authors propose an effective prediction method for growth users and evaluate the effectiveness of their proposed method.
Polycystic Ovary-Like Abnormalities (PCO-L) in women with functional hypothalamic amenorrhea.

CONTEXT In the general population, about 30% of asymptomatic women have polycystic ovary-like abnormalities (PCO-L), i.e. polycystic ovarian morphology (PCOM) at ultrasound and/or increased anti-Müllerian hormone (AMH) serum level. PCOM has also been reported in 30-50% of women with functional hypothalamic amenorrhea (FHA). OBJECTIVE The aim of this study was to verify whether both PCOM and excessive AMH level indicate PCO-L in FHA and to elucidate its significance. DESIGN We conducted a retrospective analysis using a database and comparison with a control population. SETTING Subjects received ambulatory care in an academic hospital. PATIENTS Fifty-eight patients with FHA were compared to 217 control women with nonendocrine infertility and body mass index of less than 25 kg/m(2). INTERVENTIONS There were no interventions. MAIN OUTCOME MEASURES We measured serum testosterone, androstenedione, FSH, LH, AMH, and ovarian area values. The antral follicle count (AFC) was used as a binary variable (i.e. negative or positive) because of the evolution of its sensitivity over the time of this study. The ability of these variables (except AFC) to detect PCO-L in both populations was tested by cluster analysis. RESULTS One cluster (cluster 2) suggesting PCO-L was detected in the control population (n = 52; 24%), whereas two such clusters were observed in the FHA population (n = 22 and n = 6; 38 and 10%; clusters 2 and 3, respectively). Cluster 2 in FHA had similar features of PCO-L as cluster 2 in controls, with higher prevalence of positive AFC (70%) and PCOM (70%), higher values of ovarian area and higher serum AMH (P < 0.0001 for all), and testosterone levels (P < 0.01) than in cluster 1. Cluster 3 in FHA was peculiar, with frankly elevated AMH levels. In the whole population (controls + FHA), PCO-L was significantly associated with lower FSH values (P < 0.0001). CONCLUSION PCO-L in FHA is a frequent and usually incidental finding of unclear significance, as in controls. The association of PCO-L with hypothalamic amenorrhea should not lead to a mistaken diagnosis of PCOS.
Qualitative research: what it is and what it can contribute to cardiology in the young

I N THIS ISSUE OF CARDIOLOGY IN THE YOUNG, Rempel and colleagues present a study using qualitative research that gives new insights into how mothers and fathers parent children with hypoplastic left heart syndrome who have survived the Norwood surgical procedure. Using interviews with parents, the study conveys the wide range, and intensity, of challenges faced by parents as they dealt with complicated emotions about the illness of their children. With great happiness and joy that their child has survived, the parents sought to maintain normality amidst ongoing uncertainty and anxiety over the future developments for their offspring Health professionals did little to address the emotions, concerns, and needs of the parents. As a result, over years, the parents often felt unsupported. This study addresses not only a vulnerable young population, but also provides insights for health professionals about the experiences and needs of parents which can inform clinical practice. The methods used in the study, however, may raise some curiosity or concern. What is qualitative research? And how should its quality be judged? How can any research based on a small number of participants be trusted? How can change to practice from a study that is not a randomized control trial even be contemplated? What is qualitative research?

Also, it was indicated that quality of relationship has a significant effect on outcomes (continuous communication and verbal marketing) in Mellat Bank.
Corneal Oxygen Distribution With Contact Lens Wear

Purpose: Since 1991, multilayer mathematical in vivo oxygenation models have been created to predict normal corneal oxygenation with contact lens wear. From these models, there have been assertions that most hydrogel contact lenses allow 97%-98% of normal corneal oxygenation compared to no contact lens wear. In light of hydrogel lens-induced neovascularization and limbal hyperemia, to clinicians, this finding seems counterintuitive. This work seeks to validate or refute those preexisting models and estimate the impact of contact lens wear on the oxygen distribution profile across the cornea. To this end, to estimate the impact of contact lens wear on the 3-dimensional (3-D) oxygen distribution profile within the cornea as a function of the oxygen permeability of the contact lens, a two-dimensional axisymetric finite element analysis (FEA) model was constructed for contact lenses, on the cornea, both having varying thickness profiles. Methods: A two dimensional (2-D) axi-symetric finite element analysis (FEA) model of a −3.00 D contact lens on eye was constructed. The model included the varying thickness profiles of the contact lens and cornea. By symmetry, this 2-D model is equivalent to a full 3-D model. The oxygen permeability, material thickness profile, and oxygen consumption coefficients from Brennan (Optometry and Vision Science, June 2005) were used for this validation. Several different oxygen consumption profiles were also considered. Oxygen partial pressure, flux, and consumption profiles were generated. Results: Profiles of the oxygen partial pressure, flux, and consumption were generated from the central cornea to the limbal junction. Conclusion: This FEA model reproduced Brennan 8-layer model (BEL model) results at the central cornea. However, BEL model parameters yielded regions of oxygen deficiency in the corneal periphery, even in the open eye with no contact lens. If the BEL model cannot account for oxygenation across the whole cornea, it may be incorrect or incomplete. This assertion calls into question any conclusions from the BEL model regarding the minimum contact lens transmissibility needed to fully oxygenate the eye.
