Adolescent/Young Adult Romantic Relationships and Psychopathology

Navigating romantic relationships in adolescence/young adulthood is a normative developmental task that can be both pleasurable and challenging for youth. The success with which one does so is both predicted by and subsequently affects psychological well-being. This chapter reviews the literature on the associations between psychopathology and youth romantic relationships and experiences. We focus particularly on internalizing and externalizing disorders, for which the bulk of the literature exists. We also cover eating disorders and attention-deficit/hyperactivity disorder (ADHD) as well as other disorders and issues of comorbidity. Following the reviews of specific disorders and symptoms, we review the emerging literature on psychopathology and same-sex relationships among youth. We then address key peer and family contexts in which psychopathology and skills for romantic relationships are developing, and we discuss the intergenerational transmission of psychopathology and romantic dysfunction. The chapter closes with discussions of methodological issues and implications for prevention and intervention, emphasizing the need for ongoing basic research that can translate into novel approaches that can treat or prevent youth romantic dysfunction and psychopathology. Keywords: adolescent; romantic relationships; dating; psychopathology; intimate partner violence; intergenerational transmission; prevention
Automated software transplantation

Automated transplantation would open many exciting avenues for software development: suppose we could autotransplant code from one system into another, entirely unrelated, system. This paper introduces a theory, an algorithm, and a tool that achieve this. Leveraging lightweight annotation, program analysis identifies an organ (interesting behavior to transplant); testing validates that the organ exhibits the desired behavior during its extraction and after its implantation into a host. While we do not claim automated transplantation is now a solved problem, our results are encouraging: we report that in 12 of 15 experiments, involving 5 donors and 3 hosts (all popular real-world systems), we successfully autotransplanted new functionality and passed all regression tests. Autotransplantation is also already useful: in 26 hours computation time we successfully autotransplanted the H.264 video encoding functionality from the x264 system to the VLC media player; compare this to upgrading x264 within VLC, a task that we estimate, from VLC's version history, took human programmers an average of 20 days of elapsed, as opposed to dedicated, time.
Compact (and accurate) early vision processing in the harmonic space

The efficacy of anisotropic versus isotropic filtering is anayzed with respect to general phase-based metrics for early vision attributes. We verified that the spectral information content gathered through oriented frequency channels is characterized by high compactness and flexibility, since a wide range of visual attributes emerge from different hierarchical combinations of the same channels. We observed that it is preferable to construct a multichannel, multiorientation representation, rather than using a more compact representation based on an isotropic generalization of the analytic signal. The complete harmonic content is then combined in the phaseorientation space at the final stage, only, to come up with the ultimate perceptual decisions, thus avoiding an “early condensation” of basic features. The resulting algorithmic solutions reach high performance in real-world situations at an affordable computational cost.
Very low force-generating ability and unusually high temperature dependency in hummingbird flight muscle fibers

SUMMARY Hummingbird flight muscle is estimated to have among the highest mass-specific power output among vertebrates, based on aerodynamic models. However, little is known about the fundamental contractile properties of their remarkable flight muscles. We hypothesized that hummingbird pectoralis fibers generate relatively low force when activated in a tradeoff for high shortening speeds associated with the characteristic high wingbeat frequencies that are required for sustained hovering. Our objective was to measure maximal force-generating ability (maximal force/cross-sectional area, Po/CSA) in single, skinned fibers from the pectoralis and supracoracoideus muscles, which power the wing downstroke and upstroke, respectively, in hummingbirds (Calypte anna) and in another similarly sized species, zebra finch (Taeniopygia guttata), which also has a very high wingbeat frequency during flight but does not perform a sustained hover. Mean Po/CSA in hummingbird pectoralis fibers was very low – 1.6, 6.1 and 12.2 kN m−2, at 10, 15 and 20°C, respectively. Po/CSA in finch pectoralis fibers was also very low (for both species, ~5% of the reported Po/CSA of chicken pectoralis fast fibers at 15°C). Q10-force (force generated at 20°C/force generated at 10°C) was very high for hummingbird and finch pectoralis fibers (mean=15.3 and 11.5, respectively) compared with rat slow and fast fibers (1.8 and 1.9, respectively). Po/CSA in hummingbird leg fibers was much higher than in pectoralis fibers at each temperature, and the mean Q10-force was much lower. Thus, hummingbird and finch pectoralis fibers have an extremely low force-generating ability compared with other bird and mammalian limb fibers, and an extremely high temperature dependence of force generation. However, the extrapolated maximum force-generating ability of hummingbird pectoralis fibers in vivo (~48 kN m−2) is substantially higher than the estimated requirements for hovering flight of C. anna. The unusually low Po/CSA of hummingbird and zebra finch pectoralis fibers may reflect a constraint imposed by a need for extremely high contraction frequencies, especially during hummingbird hovering.
Experiences of Parents and Professionals in Well-Established Continuity of Care Infant Toddler Programs

ABSTRACT Research Findings: A qualitative descriptive study was conducted to look at the nature of continuity of care by examining the perspectives of those who lived it in 2 programs in which it was a well-established practice. The 35 participants included infant toddler caregivers, parents, preschool teachers, and administrators. Findings are organized around 8 features of continuity of care revealed in the study: increased knowledge (increased understanding of child development and individual children), stable relationships (decreased disruption associated with frequent transitions), a family-type atmosphere (trust, warmth, and affection promoted), primary caregiving (changing nature of roles over time), family-centeredness (mutual empowerment of parents and caregivers), effective caregiver partnerships (caregiving relationships among caregivers), the transition to preschool (higher levels of ability in social and self-help skills among children), and recommendations for improvement. Practice or Policy: We discuss implications for practitioners, teacher educators and policymakers, including further consideration of parental/caregiver empowerment, the maintenance of continuity across members of caregiving teams, and keeping children ages birth to 5 together in 1 setting. Also, findings suggest differences in the nature of primary caregiving in continuous versus discontinuous care settings. Finally, we conclude that continuity is beneficial, but complex, and more likely to succeed in programs already committed to engagement in strong, relationship-based practice.
Obesity among US urban preschool children: relationships to race, ethnicity, and socioeconomic status.

OBJECTIVES To determine whether there are racial/ethnic differences in the prevalence of obesity among preschool children and to determine whether these differences are explained by socioeconomic factors. DESIGN Cross-sectional assessment. SETTING Twenty large US cities, from 2001 to 2003. PARTICIPANTS Of the 4898 children enrolled at birth in the Fragile Families and Child Well-being Study, we analyzed data for the 2452 who, at the age of 3 years, had their height and weight measured during a maternal survey. MAIN EXPOSURES Three socioeconomic indicators were the main exposures-maternal education, household income, and children's food security status, as assessed by the US Household Food Security Survey Module. MAIN OUTCOME MEASURE Obesity, defined as a body mass index at the 95th percentile or higher for age and sex. RESULTS Of the mothers, 41.0% had education beyond high school, 52.9% of households had an income above the federal poverty threshold, and 79.5% of the children were food secure. The prevalence of obesity was 25.8% among Hispanics (any race), 16.2% among blacks, and 14.8% among whites. Compared with whites, the odds of obesity were significantly higher in Hispanics (odds ratio, 2.00; 95% confidence interval, 1.46-2.73), but not in blacks (odds ratio, 1.10; 95% confidence interval, 0.82-1.48). Neither of these odds ratios changed meaningfully after adjusting for all 3 socioeconomic indicators (Hispanics: odds ratio, 1.86 [95% confidence interval, 1.33-2.60]; and blacks: odds ratio, 1.07 [95% confidence interval, 0.78-1.47]). CONCLUSION In a sample of preschool children drawn from 20 large US cities, the high prevalence of obesity among Hispanics relative to blacks or whites was not explained by racial/ethnic differences in maternal education, household income, or food security.
Effect of Obesity on Prone Percutaneous Nephrolithotomy Outcomes: A Systemic Review.

PURPOSE With decreased physical activity, growing sedentary lifestyle, and high fat diet, obesity has become a pandemic disease all over the world. In this review, we aim to assess the effect of obesity on prone percutaneous nephrolithotomy. (PNL) outcomes. MATERIALS AND METHODS We performed a comprehensive review of the published articles in PubMed®, Medline, Scopus, Cochrane database from January 1, 2004 through June 31, 2015, using the key words; body mass index, obesity, morbid obesity, super obese, urolithiasis, nephrolithiasis, percutaneous nephrolithotomy and percutaneous lithotripsy. Original research articles published in English language with accessibility to the full text article were analyzed for our review. RESULTS At the end of the evaluation, we found 12 articles in English language, analyzing the effect of obesity on prone PNL outcomes. Except one study, eleven studies were evaluated in this review had a retrospective nature without randomization. Stone free status of patients was in a wide range between 49%-90% in obese patients and 41%-90% in morbid obese patients. CONCLUSION PNL is a safe and effective treatment modality for renal stone(s) in obese and morbid obese patients. However, effect of body mass index on PNL outcomes including operation time, fluoroscopy screening time, hospitalization time, complications and stone free status are still debatable.
The key role of shared participation in changing occupational self‐efficacy through stress management courses

This study is the first that longitudinally examined change in occupational self-efficacy (OSE) through individual and shared participation in occupational stress management courses (SMC). Applying the framework of social cognitive theory (Bandura, 1986, Social foundations of thought and action: A social cognitive theory. Englewood Cliffs, NJ: Prentice-Hall), we assumed that participation in SMC facilitates OSE perceptions. We further assumed that the psychosocial environment promotes change in OSE through high shared participation (reach) in SMC within work groups. Comparing participants and non-participants, we conducted growth analyses with three waves of data nested in n = 545 employees further nested in 97 work groups. The results showed that individual participation in SMC alone was insufficient to enhance OSE, a combination of individual and high shared participation being needed to significantly enhance OSE perceptions over a period of 2 years. The results are discussed with reference to specificity issues and the role of the psychosocial environment by applying social identity theory and the notion of shared mental models. We conclude by recommending SMC as a feasible intervention to enhance OSE in heterogeneous occupational contexts – if a majority of work group members can be involved
Lower Plasma Creatinine and Urine Albumin in Individuals at Increased Risk of Type 2 Diabetes with Factor V Leiden Mutation

The factor V Leiden (FVL) mutation is the most frequent genetic cause of venous thrombosis in Caucasians. However, protective effects have been suggested to balance the disadvantages. We have recently observed protective effects of FVL mutation on experimental diabetic nephropathy in mice as well as an association with reduced albuminuria in two human cohorts of diabetic patients. In the present study we aimed to reevaluate these findings in an independent, larger cohort of 1905 Caucasians at risk of developing type 2 diabetes and extend possible associations to earlier disease stages of nephropathy. Carriers of FVL mutation had a significantly lower urine albumin excretion (P = 0.03) and tended to have lower plasma creatinine concentrations (P = 0.07). The difference in plasma creatinine concentrations was significant after adjustment for the influencing factors: age, gender, and lean body mass (P = 0.048). These observations at a very early “disease” stage are an important extension of previous findings and suggest that modification of glomerular dysfunction by FVL mutation is relevant during very early stages of diabetic nephropathy. This makes the underlying mechanism an interesting therapeutic target and raises the question whether FVL mutation may also exert protective effects in other glomerulopathies.
Burden of reduced work productivity among people with chronic knee pain: a systematic review

Objective The aims of this systematic review were to determine the prevalence of reduced work productivity among people with chronic knee pain as well as specifically categorise determinants of work productivity losses into individual, disease and work-related factors, conduct an evaluation of study methodological quality and present a best-evidence synthesis. Methods We searched the literature using combinations of key words such as knee pain, knee osteoarthritis, absenteeism (days taken off work) and presenteeism (reduced productivity while at work) for observational studies published in English. Methodological quality appraisal and a best-evidence synthesis were used to pool the study findings. Results The studies were conducted exclusively in high income countries of North America, Western Europe and Hong Kong. 17 studies were included in the review, 10 measuring absenteeism and six measuring presenteeism. Of the 10 studies reporting absenteeism, seven found a 12-month absenteeism prevalence ranging from 5% to 22%. Only two studies evaluated presenteeism prevalence and reported a range from 66% to 71%. Using best-evidence synthesis: three high quality cohort studies and three cross-sectional studies provided strong evidence that knee pain or knee osteoarthritis was associated with absenteeism; two high quality cross-sectional studies and one cohort study provided limited evidence for an association with presenteeism; one cross-sectional study provided limited evidence for an association among age, high job demands and low coworker support and absenteeism among nurses with knee pain. No studies examined individual or work-related factors associated with presenteeism. Conclusions A number of high quality studies consistently demonstrated that chronic knee pain or knee osteoarthritis is associated with absenteeism. However, data are lacking regarding presenteeism and individual or work-related risk factors for reduced work productivity among older workers with chronic knee pain.

Risk‐tailored CNS prophylaxis in a mono‐institutional series of 200 patients with diffuse large B‐cell lymphoma treated in the rituximab era

The most effective strategy to prevent central nervous system (CNS) dissemination in diffuse large B‐cell lymphoma (DLBCL) remains an important, unmet clinical need. Herein, we report a retrospective analysis of risk‐tailored CNS prophylaxis in 200 human immunodeficiency virus‐negative adults with DLBCL treated with rituximab‐CHOP (cyclophosphamide, doxorubicin, vincristine, prednisone) or similar. High risk of CNS relapse was defined by involvement of specific extranodal organs, or simultaneous presence of advanced stage and high serum lactate dehydrogenase level; CNS prophylaxis with high‐dose methotrexate ± intrathecal chemotherapy (IT) was routinely used in high‐risk patients diagnosed after 2007. CNS relapse risk was low in 93 patients and high in 107; 40 high‐risk patients received prophylaxis, which consisted of IT alone in 7. At a median follow‐up of 60 months, one low‐risk and nine high‐risk patients (1% vs. 8%; P = 0·01) experienced CNS relapse. In the high‐risk group, CNS relapses occurred in 8/67 (12%) patients who did not receive prophylaxis and in 1/40 (2·5%) patients who did; the latter occurred in a patient managed with IT alone. CNS relapse rate was 12% (9/74) for patients treated with “inadequate” prophylaxis (none or IT only) and 0% (0/33) for patients managed with intravenous prophylaxis (P = 0·03). In conclusion, high‐dose methotrexate‐based prophylaxis significantly reduces CNS failures in high‐risk patients stratified by involvement of specific extranodal sites and International Prognostic Index.
Labor Market Flows and Equilibrium Search Unemployment

This paper explicitly differentiates between unemployment and inactivity, by defining inactivity as a state in which individuals do not search for jobs when non-employed. Facing changes in the value of inactivity, individuals transit through three labor market states. In steady-state, we hence have a theory of equilibrium unemployment determined by both matching frictions and labor market participation margins. The paper firstly rationalizes and quantitatively accounts for the existence of large flows between employment, unemployment and inactivity. Secondly, it shows that unemployment and aggregate wages rise because some of the employed workers are unattached to the labor force, in the sense that they join the inactive pool when they lose a job. Thirdly, unemployment income has little effects on employment, since it attracts people into the labor force and rises the share of attached workers. Finally, our theory suggests that contrary to two-state models, taxation of market activity increases non-participation, unattachment and adversely affects unemployment.
Active Deception Detection

Actively detecting deception requires (a) gathering information for fact-checking the communication content, (b) strategically prompting deception cues, and (c) encouraging honest admissions and discouraging continued deceit. Most deception-detection research, active or otherwise, finds that people are only slightly better than chance at correctly distinguishing truth from lies. Poor accuracy stems from a lack of reliable deception cues that hold across people and situations. Consequently, basing lie detection on deception cues is prone to error. However, some approaches to active deception detection yield higher accuracy than passive observation. Not all active approaches are advantageous. Mere interaction and mere question-asking produce outcomes similar to passive observation. Evidence-based and confession-solicitation approaches can be highly effective: for example, strategic use of evidence (SUE) and the content in context approach.
Quantum Encoder and Decoder for Secret Key Distribution with Check Bits

The focus of this study is to develop a novel method of encoding the qubits and use as secret key in public key cryptography. In BB 84 protocol, 50% of the random number (generated at source) is used as secret key and the remaining bits are used as "check bits". The check bits are used to detect the presence of eve as well as the nature of quantum channels. In this protocol, random qubits are encoded using different type of polarizations like horizontal, veritical and diagonal. In the proposed quantum encoder, basic quantum gates are used to encode the random secret key along with the check bits. Quantum key distribution, (a cryptographic mechanism) relies on the inherent randomness of quantum mechanics and serves as an option to replace techniques made vulnerable by quantum computing. However, it is still subject to clever forms of eavesdropping and poses a significant challenge to implementation. To study the challenges, quantum circuits are first simulated using QCAD.
The Magnitude of Obesity and its Relationship to Blood Pressure Among the Residents of Enugu Metropolis in South East Nigeria

Background: Obesity in developing nations is no longer as uncommon as it was thought to be decades ago however paucity of data on the burden of obesity from urban communities was observed by previous workers. Aim: To determine the magnitude of obesity and its relationship to blood pressure among urban adult residents in Enugu metropolis. Subjects and Methods: A cross-sectional community survey of adults who were not known to have diabetes or hypertension by self-report was carried out. Four parts of the metropolis selected by simple random sampling were used and consenting individuals aged 18-70 years were consecutively recruited. Anthropometric measurements were done using standard procedures as specified in the World Health Organization STEPs instrument. Obesity was determined using widely acknowledged body mass index (BMI) ≥30 kg/m 2 . Descriptive and inferential statistical analyses was performed using SPSS with P value set at <0.05. Results: A high prevalence of obesity of 21.2% (95% confidence interval [CI]: 18.3-24.1) was found among the participants with significant female gender preponderance. The burden increased with age with the middle age group highly involved. Attainment of age of 40 years and above had an increased odd of developing obesity (odds ratio = 1.8; 95% CI: 1.3-2.6). There was a relationship between blood pressure and BMI as shown by positive correlation, higher BMI among hypertensive subjects and high burden of elevated blood pressure among obese subjects (91/164; 55.5%). Conclusion: A high magnitude of obesity existed among this apparently healthy unaware adults resident in an urban Nigerian city and obesity is associated with elevation in blood pressure.
