Quantifying Joint Coordination Variability in Anterior Cruciate Ligament-Reconstructed Individuals During Walking

The knee is the second most common joint to sustain injury. An estimated 200,000 anterior cruciate ligament (ACL) ruptures occur each year in the United States alone, and about 100,000 ACL reconstruction (ACLR) surgeries are performed annually. There is a significant risk of developing osteoarthritis of the knee after incurring an ACL injury, and the incidence of ipsilateral or contralateral injury is six times greater in individuals who have a surgically repaired ACL. Past studies have analyzed kinetic and kinematic characteristics of individual lower extremity joints to reveal differences between subjects with and without ACLR. Despite reports of altered kinematic performance in individuals with ACLR compared to healthy controls, most of the analyses did not evaluate coordinative function, and thus neglected to consider how the lower limb acts as a linked chain. Therefore, the present study used a method based on dynamical systems theory to quantify coordination and account for the interaction between joints in the lower extremity. The purpose of the study was to quantify and compare joint coordination variability and joint coordination patterns between individuals with ACLR and matched controls. Institutional Review Board (IRB) approval was obtained prior to data collection, and all subjects signed an informed consent form. Twenty subjects (nine females, eleven males; body mass index (BMI) 25±3.5 kg/m2) who had undergone unilateral ACLR (thirteen right, seven left) and been cleared to return to full activity were compared to twenty control subjects matched by gender and BMI (nine females, eleven males; BMI 22.4±2.4 km/m2). Kinematic and kinetic data during walking were collected in the UTHSC Motion Analysis Laboratory. A vector coding technique was used to calculate coupling angles for six joint couplings involving the hip, knee, and ankle across four periods within the stance phase. Joint coordination variability was defined as the standard deviation of the coupling angle between trials within a subject, and joint coordination patterns were based on coupling angle magnitude. Individuals with ACLR exhibited increased joint coordination variability and altered joint coordination patterns compared to the matched controls during the stance phase of walking. These results suggested that coordinative function may not be fully restored in individuals with ACLR following rehabilitation. Increased coordination variability from a normal, or optimal amount as well as altered coordination patterns may result from a deficit in sensorimotor control, and represent risk of re-injury. Further investigation that is prospective, focuses primarily on hip-knee coupled motion in frontal and transverse planes, and includes assessment of EMG in addition to kinematics may contribute relevant information for improving ACL injury prevention and rehabilitation.
Gender differences in the timing of first intercourse: data from 14 countries.

Data from the most recent nationally representative surveys of reproductive behavior in 14 countries throughout the world were used to assess regional variations in young peoples sexual behavior. Analyses focus on 15-19 year olds but also use data from 20-24 year olds to provide a more complete picture of gender differences in behavior during adolescence. In most countries roughly one-third or more of teenage women have had intercourse; in four countries (Ghana Mali Jamaica and Great Britain) about 3 in 5 are sexually experienced. Between about one-half and three-quarters of adolescent males in seven countries have ever had intercourse but the proportion is one-third or less in Ghana Zimbabwe the Philippines and Thailand. In most countries sexual intercourse during the teenage years occurs predominantly outside marriage among men but largely within marriage among women. Never married young people are considerably less likely to be currently sexually active than to be sexually experienced. For example in Ghana 49% of never-married adolescent women have had intercourse but only 23% have done so within the past month. In most of these countries a high proportion of adolescents is potentially at risk for a range of poor reproductive health outcomes. Program planners must find ways to help sexually active adolescents consistently use effective means of protection against both pregnancy and sexually transmitted diseases. (authors)
Dealing with economic and demographic challenges: workplace innovation practices as a timely and effective response to older workers' needs

Abstract There is substantial evidence that workplace practices can support employee health and well-being. In the present paper we explore the role of a specific type of practices, workplace innovation (WI) practices, for older workers’ health and well-being. We start by arguing for a more comprehensive and less fragmented approach to workplace practices and for practices that can create the conditions to support both quality of working life and organisational performance. We then suggest that WI practices offer such an approach and present the evidence that links the effects of four types of WI practices (work organisation, structure and systems, learning and reflection, and workplace partnership) to a range of health and well-being outcomes (health, well-being, work engagement, performance, and decisions to delay retirement). Even though there is currently no direct empirical evidence that links WI practices to the health and well-being of older workers, the available research offers indirect support for a number of propositions for research and practice. These propositions can help and contribute to the development of a fruitful line of research on the impact of WI on older workers’ health and well-being. Keywords: Older workers, workplace innovation practices, human resource management, health, well-being, work engagement, performance, retirement
An occurrence of staurolite in the Llano uplift , central Texas

Staurolite, not previously reported from the Precambrian metamorphic rocks of the Llano uplift ofcentral Texas, occurs as inclusions in a spessartine-rich garnet from a biotite gneiss in the Rough Ridge Formation of the Packsaddle Group. The initial crystallization of staurolite and its subsequent elimination from the quartzose micaceous matrix surrounding the garnet may require a more complex metamorphic history than has so far been documented for these rocks.
Calcium and dairy intake in bone health during adolescence

Adolescence, as defined by the World Health Organization (WHO), is the period in human growth and development that occurs after childhood and before adulthood, from ages ten to 19 years. Adolescence is the critical period for bone accrual and the development of peak bone mass (PBM). PBM, the maximum amount of bone acquired at skeletal maturity, will determine fracture risk and in turn be a determining factor for osteoporosis later in life. It has been said that 60% of the risk for osteoporosis can be explained by the amount of bone mineral laid down in the early years of life, and 40 60% of adult bone mass is acquired during the pubertal growth spurt; with 25% PBM acquired during the two years surrounding peak height velocity. Bone density and bone growth are dependent on various factors that affect the development of PBM. Approximately 60-80% of the PBM that is developed is genetically determined. The remaining 20-40% is determined by diet, physical activity, hormones and medications. The promotion of healthy bones is essential in the short-term to prevent fractures, but also in the long-term prevention of osteoporosis in the elderly.
Metalized polymer tubes for high-frequency electromagnetic waveguiding.

Low loss electromagnetic energy transport over long distances motivates the development of different types of waveguiding systems. Requirements of high quality optically polished waveguide surfaces needed in high-frequency applications and low-cost manufacturing are practically incompatible in current realizations. Here we demonstrate a new paradigm solution, based on surface functionalization with subsequent electroless plating of conductive micron smooth copper layer on the inner surface of flexible non-conducting poly-carbonate tubes. The structure was shown to support moderately low loss guiding performances (~5-10 dB/m) at Ku-band. The mechanically flexible design of the system allows shaping the waveguide network almost on demand. In particular, an efficient energy guiding over a closed loop with 8 lambda radius was demonstrated. The new platform of high quality metalized flexible waveguiding systems opens new opportunities in designs of cheap and efficient networks, operating over a broad spectral range, approaching tens of GHz and even higher.
Classification of Bicycle Traffic Patterns in Five North American Cities

This study used a unique database of long-term bicycle counts from 38 locations in five North American cities and along the Route Verte in Quebec, Canada, to analyze bicycle ridership patterns. The cities in the study were Montreal, Quebec; Ottawa, Ontario; and Vancouver, British Columbia, in Canada and Portland, Oregon, and San Francisco, California, in the United States. Count data showed that the bicycle volume patterns at each location could be classified as utilitarian, mixed utilitarian, mixed recreational, and recreational. Study locations classified by these categories were found to have consistent hourly and weekly traffic patterns across cities, despite considerable differences between the cities in their weather, size, and urban form. Seasonal patterns across the four categories and in the cities also were identified. Expansion factors for each classification are presented by hour and day of the week. Monthly expansion factors are presented for each city. Finally, traffic volume characteristics are presented for comparison purposes.
Carbon Sources in Fruit Carbonate of Buglossoides arvensis and Consequences for 14C Dating

Abstract Fruit carbonate of Buglossoides arvensis (syn. Lithospermum arvense) is a valuable dating and paleoenvironmental proxy for late Quaternary deposits and cultural layers because CaCO3 in fruit is assumed to be accumulated from photosynthetic carbon (C). However, considering the uptake of HCO3 – by roots from soil solution, the estimated age could be too old depending on the source of HCO3 – allocated in fruit carbonate. Until now, no studies have assessed the contributions of photosynthetic and soil C to the fruit carbonate. To evaluate this, the allocation of photo-assimilated carbon and root uptake of HCO3 – was examined by radiocarbon (14C) labeling and tracing. B. arvensis was grown in carbonate-free and carbonate-containing soils (sand and loess, respectively), where 14C was provided as (1) 14CO2 in the atmosphere (5 times shoot pulse labeling), or (2) Na2 14CO3 in soil solution (root-labeling; 5 times by injecting labeled solution into the soil) during one month of fruit development. Distinctly different patterns of 14C distribution in plant organs after root- and shoot labeling showed the ability of B. arvensis to take up HCO3 – from soil solution. The highest 14C activity from root labeling was recovered in roots, followed by shoots, fruit organics, and fruit carbonate. In contrast, 14C activity after shoot labeling was the highest in shoots, followed by fruit organics, roots and fruit carbonate. Total photo-assimilated C incorporated via shoot labeling in loess-grown plants was 1.51 mg lower than in sand, reflecting the presence of dissolved carbonate (i.e. CaCO3) in loess. Loess carbonate dissolution and root-respired CO2 in soil solution are both sources of HCO3 – for root uptake. Considering this dilution effect by carbonates, the total incorporated HCO3 – comprised 0.15% of C in fruit carbonate after 10 hr of shoot labeling. However, if the incorporated HCO3 – during 10 hr of shoot labeling is extrapolated for the whole month of fruit development (i.e. 420-hr photoperiod), fruit carbonate in loess-grown plants incorporated approximately 6.3% more HCO3 – than in sand. Therefore, fruit carbonates from plants grown on calcareous soils may yield overestimated 14C ages around 500 yr because of a few percentage uptake of HCO3 – by roots. However, the age overestimation because of HCO3 – uptake becomes insignificant in fruits older than approximately 11,000 yr due to increasing uncertainties in age determination.
Coping and Helping to Cope: Perspectives of Children of Palestinian Political Detainees

This qualitative study investigates how children of Palestinian political detainees in Israeli detention cope with their fathers' absences. Researchers conducted 16 semi‐structured interviews with children, mostly aged 15 and older in the West Bank. Three themes are discussed that emerged from the interview data: how children cope with their sadness; the children's perspectives on community support; and older children's support to siblings and parents. Practitioners can support children by providing counselling to mothers and organising interventions, which give children the opportunity to connect. It is important that the agency of the older children is taken into account and built upon.
Measuring Social Influence Using Eye-Tracking in a Between-Groups User-Study

The decision success of a group is strongly related to its members’ satisfaction while adapting to common outcomes that, in turn, relate to familiarity and trust. Thus, the evaluation of determinant factors enhancing group dynamics is essential for understanding social influence in a group setting. This paper presents the design and results of a group influence study in a music scenario, in which people share their tastes and participate in-group decisions. We designed and ran a between-groups experiment with the purpose of tracking group influence in our GroupFun music recommender system. Specifically, we were interested in measuring the extent to which people change their opinions when facing various individual preferences supported by other group members. Two groups of 9 and 10 members are evaluated one against the other by means of comparing decision acceptance, participant satisfaction and decision changes using an online questionnaire, songs’ ratings and eye-tracking data. The eye tracking outputs we used present clear associations between various areas of the interest while fixation times are useful to understand group influence relative to closest members. Our results focus on group conformity, or the degree to which individuals change their own rating aligning to the group decision. We prove that the stronger social relationships (through familiarity and trust) are in a group, the more its members adapt to a common decision and are more inclined to change their preferences.
An unusual very low-mass high-amplitude pre-main sequence periodic variable

Aims. We have investigated the nature of the variability of CHS 7797, an unusual periodic variable in the Orion Nebula Cluster. Methods. An extensive I-band photometric data set of CHS 7797 was compiled between 2004-2010 using various telescopes. Further optical data have been collected in R and zbands. In addition, simultaneous observations of the ONC region including CHS 7797 were performed in the I, J, Ks & IRAC 3.6 and 4. 5µm bands over a time interval of≈ 40 d. Results. CHS 7797 shows an unusual large-amplitude variation of≈ 1.7 mag in the R, I, and zbands with a period 17.786 ± 0.03 d (FAP = 1x10 −15 %). The amplitude of the brightness modulation decreases only slightly at longer wavelengths. The star is faint during≈ 2/3 of the period and the shape of the phased light-curves for the seven different observing seasons shows minor changes and small-amplitude variations. Interestingly, there are no significant colour-flux correlations for �. 2µm, while the object becomes redder when fainter at longer wavelengths. CHS 7797 has a spectral type of M6 and an estimated mass between 0.04-0.1 M⊙. Conclusions. The analysis of the data suggests that the periodic variabil ity of CHS 7797 is most probably caused by an orbital motion. Variability as a result of rotational brightness modulatio n by a hot spot is excluded by the lack of any colour-brightness correlation in the optical. The latter indicates that CHS 7797 is most probably occulted by circumstellar matter in which grains have grown from typical 0.1 µm to≈ 1-2µm sizes. We discuss two possible scenarios in which CHS 7797 is periodically eclipsed by structures in a disc, namely that CHS 7797 is a single object with a circumstellar disc, or that CHS 7797 is a binary system, similar to KH 15D, in which an inclined circumbinary disc is responsible of the variability. Possible reasons for the typical 0.3 mag variati ons in I-band at a given phase are discussed.
Serum n 2 6 fatty acids and lipoprotein subclasses in middle-aged men : the population-based cross-sectional ERA-JUMP Study 1 – 3

Background: The associations of serum omega-6 (n26) fatty acids with lipoprotein subclasses at the population level are uncertain. Objective: We aimed to examine associations between major n26 fatty acids [ie, linoleic acid (LA, 18:2n26) and arachidonic acid (AA, 20:4n26)] and the lipoprotein subclasses VLDL, LDL, and HDL. Design: We conducted a cross-sectional study in 1098 participants using population-based data from US white, Japanese American, Japanese, and Korean men aged 40–49 y. Serum fatty acids were analyzed by capillary gas-liquid chromatography. Lipoprotein subclasses were measured by nuclear magnetic resonance spectroscopy. Multiple linear regression models as a function of each fatty acid were used after adjustment for age, population, body mass index, pack-years of smoking, alcohol consumption, diabetes, hypertension, and omega-3 (n23) and trans fatty acids. Results: Serum LAwas inversely associated with large VLDL (b = 20.62, P , 0.001), total LDL (b = 222.08, P , 0.001), and small LDL (b = 231.89, P , 0.001) particle concentrations and VLDL size (b = 20.72, P , 0.001). Serum LA was positively associated with large HDL particle concentration (b = 0.21, P , 0.001) and HDL size (b = 0.03, P , 0.001). The patterns of association of AA with large VLDL and large HDL particle concentrations were comparable with those of LA. Conclusions: At the population level, higher serum concentrations of LA were significantly associated with lower concentrations of total LDL particles. Higher serum concentrations of LA and AA were significantly associated with a lower concentration of large VLDL particles and a higher concentration of large HDL particles. These associations were consistent across the population groups. This trial was registered at clinicaltrials.gov as NCT00069797. Am J Clin Nutr 2010;91:1195–203.

Temperate and boreal forest mega‐fires: characteristics and challenges

Mega-fires are often defined according to their size and intensity but are more accurately described by their socioeconomic impacts. Three factors – climate change, fire exclusion, and antecedent disturbance, collectively referred to as the “mega-fire triangle” – likely contribute to today's mega-fires. Some characteristics of mega-fires may emulate historical fire regimes and can therefore sustain healthy fire-prone ecosystems, but other attributes decrease ecosystem resiliency. A good example of a program that seeks to mitigate mega-fires is located in Western Australia, where prescribed burning reduces wildfire intensity while conserving ecosystems. Crown-fire-adapted ecosystems are likely at higher risk of frequent mega-fires as a result of climate change, as compared with other ecosystems once subject to frequent less severe fires. Fire and forest managers should recognize that mega-fires will be a part of future wildland fire regimes and should develop strategies to reduce their undesired impacts.
No . 272 Climate , conflict and forced migration

Despite the lack of robust empirical evidence, a growing number of media reports attempt to link climate change to the ongoing violent conflicts in Syria and other parts of the world, as well as to the migration crisis in Europe. Exploiting bilateral data on asylum seeking applications for 157 countries over the period 20062015, we assess the determinants of refugee flows using a gravity model which accounts for endogenous selection in order to examine the causal link between climate, conflict and forced migration. Our results indicate that climatic conditions, by affecting drought severity and the likelihood of armed conflict, played a significant role as an explanatory factor for asylum seeking in the period 2011-2015. The effect of climate on conflict occurrence is particularly relevant for countries in Western Asia in the period 2010-2012 during when many countries were undergoing political transformation. This finding suggests that the impact of climate on conflict and asylum seeking flows is limited to specific time period and contexts. JEL codes: F22, Q54, D74
Evolution of Genomic Expression

Genomic regulation is key to cellular differentiation, tissue morphogenesis, and development. Increasing evidence indicates that evolutionary diversity of phenotypes—from cellular to organismic—may also be, in large part, the result of variation in the regulation of genomic expression. In this chapter we explore the complexity of gene regulation from the perspective of single genes and whole genomes. The first part describes the major factors affecting gene expression levels, from rates of gene transcription—as mediated by promoter–enhancer interactions and chromatin modifications—to rates of mRNA degradation. This description underscores the multiple levels at which genomic expression can be regulated as well as the complexity and variety of mechanisms used. We then briefly describe the major experimental and computational biology techniques for analyzing gene expression variation and its underlying causes. The final section reviews our understanding of the role of regulatory variation in evolution, including the molecular evolution and population genetics of noncoding DNA, as well as the inheritance and phenotypic evolution of levels of mRNA abundance.
