Indicators of river system hydromorphological character and dynamics: understanding current conditions and guiding sustainable river management

The work leading to this paper received funding from the EU’s FP7 programme under Grant Agreement No. 282656 (REFORM). The Indicators were developed within the context of REFORM deliverable D2.1, therefore all partners involved in this deliverable contributed to some extent to their discussion and development

Influence of Psychological Factors on Pain and Disability in Anterior Knee Pain Patients

AKP patients express chronic pain but also disability. However, the correlation between pain and disability is not complete and linear. Some patients with a lot of pain show mild disability while others with much less pain also show great disability. The disability is profoundly influenced by other emotional and cognitive factors that are associated with the perception of pain. Therefore, the clinical efforts do not have to be focused only on treating the pain as a feeling but on identifying and modifying these factor

The Critical Role of Supervision in Retaining Staff in Obstetric Services: A Three Country Study

Millennium Development Goal (MDG) 5 commits us to reducing maternal mortality rates by three quarters and MDG 4 commits us to reducing child mortality by two-thirds between 1990 and 2015. In order to reach these goals, greater access to basic emergency obstetric care (EmOC) as well as comprehensive EmOC which includes safe Caesarean section, is needed.. The limited capacity of health systems to meet demand for obstetric services has led several countries to utilize mid-level cadres as a substitute to more extensively trained and more internationally mobile healthcare workers. Although this does provide greater capacity for service delivery, concern about the performance and motivation of these workers is emerging. We propose that poor leadership characterized by inadequate and unstructured supervision underlies much of the dissatisfaction and turnover that has been shown to exist amongst these mid-level healthcare workers and indeed health workers more generally. To investigate this, we conducted a large-scale survey of 1,561 mid-level cadre healthcare workers (health workers trained for shorter periods to perform specific tasks e.g. clinical officers) delivering obstetric care in Malawi, Tanzania, and Mozambique. Participants indicated the primary supervision method used in their facility and we assessed their job satisfaction and intentions to leave their current workplace. In all three countries we found robust evidence indicating that a formal supervision process predicted high levels of job satisfaction and low intentions to leave. We find no evidence that facility level factors modify the link between supervisory methods and key outcomes. We interpret this evidence as strongly supporting the need to strengthen leadership and implement a framework and mechanism for systematic supportive supervision. This will promote better job satisfaction and improve the retention and performance of obstetric care workers, something which has the potential to improve maternal and neonatal outcomes in the countdown to 2015

Lesbian and Heterosexual Two-Parent Families: Adolescent–Parent Relationship Quality and Adolescent Well-Being

This study compared 51 adolescents from intact two-mother planned lesbian families (all conceived through donor insemination) with 51 adolescents from intact mother-father families on their relationships with their parents (parental control, disclosure to parents, and adolescent-parent relationship quality), psychological adjustment (self-esteem, social anxiety, and conduct problems), and substance usage (consumption of tobacco, alcohol, and marijuana/hashish). The adolescents (average age 16 years) were matched on demographic characteristics (age, gender, educational level, country of birth, parental birth country) with a sample from a large school-based survey, and data were collected by means of adolescent self-reports. Analyses indicated that adolescents in both family types had positive relationships with their parents, which were favorably associated with psychological well-being. On the assessments of psychological adjustment and substance use, family type was significantly associated only with self-esteem and conduct problems: Adolescents with lesbian mothers had higher levels of self-esteem and lower levels of conduct problems than their counterparts in heterosexual-parent families. Overall, the findings indicate that adolescents from intact two-mother lesbian families are comparable to those in a matched comparison group with intact mother-father families. The few differences found on psychological well-being favored the adolescents in lesbian two-mother families

The localization of NADPH oxidase and reactive oxygen species in in vitro-cultured Mesembryanthemum crystallinum L. hypocotyls discloses their differing roles in rhizogenesis

This work demonstrated how reactive oxygen species (ROS) are involved in the regulation of rhizogenesis from hypocotyls of Mesembryanthemum crystallinum L. cultured on a medium containing 1-naphthaleneacetic acid (NAA). The increase of NADPH oxidase activity was correlated with an increase of hydrogen peroxide (H2O2) content and induction of mitotic activity in vascular cylinder cells, leading to root formation from cultured hypocotyls. Diphenylene iodonium (DPI), an inhibitor of NADPH oxidase, inhibited H2O2 production and blocked rhizogenesis. Ultrastructural studies revealed differences in H2O2 localization between the vascular cylinder cells and cortex parenchyma cells of cultured explants. We suggest that NADPH oxidase is responsible for H2O2 level regulation in vascular cylinder cells, while peroxidase (POD) participates in H2O2 level regulation in cortex cells. Blue formazan (NBT) precipitates indicating superoxide radical (O2 •−) accumulation were localized within the vascular cylinder cells during the early stages of rhizogenesis and at the tip of root primordia, as well as in the distal and middle parts of newly formed organs. 3,3′-diaminobenzidine (DAB) staining of H2O2 was more intense in vascular bundle cells and in cortex cells. In newly formed roots, H2O2 was localized in vascular tissue. Adding DPI to the medium led to a decrease in the intensity of NBT and DAB staining in cultured explants. Accumulation of O2 •− was then limited to epidermis cells, while H2O2 was accumulated only in vascular tissue. These results indicate that O2 •− is engaged in processes of rhizogenesis induction involving division of competent cells, while H2O2 is engaged in developmental processes mainly involving cell growth

Sn-Sb-Se crystalline phases formed by melt-quenching technique

Preperation of alloy percentages of Sn-Sb-Se(TAS) of shaking furnace and melt sealing evacuated quartz ampoule using melt quenching technique (MQT) was analyzed. XRD measurement was carried out to identify whether the prepared samples were amorphous or crystalline structure and to determine the boundary between the two states. SEM morphological studies revealed that increasing Sn and Sb mole % modify the microstructure of the ternary Sn-Sb-Se based systems. Under the same conditions of preparation and maintaining Sn mol% at 15, the dendrite shapes of crystals were enlarged when Sb mol% increased. The Sn occurred in ternary compositions and supports the theoretical argument which considered Sb-mol %=14.3 is the boundary line between the crystalline and crystalline phase is dominant in the region with Sb-mol% more than or equal to 15. MQT proved its ability in preparing alloy of Sn-Sb-Se in crystalline structure and there was no excessive loss of the materials during the preparation
