Spatial and Temporal Modeling of Community Non-Timber Forest Extraction
This paper examines the interaction of spatial and dynamic aspects of resource extraction from forests by local people. Highly cyclical and varied across both space and time, the patterns of resource extraction resulting from the spatial-temporal model bear little resemblance to the patterns drawn from focusing either on spatial or temporal aspects of extraction, as is typical in both the modeling and empirical literature to date. Combining the spatial-temporal model with a measure of success in community forest management.the ability to avoid open-access resource degradation.characterizes the impact of incomplete property rights on patterns of resource extraction and stocks. Key words: Spatial and temporal modeling; renewable resources; non-timber forest products; common property resources
Analyzing the Impact of Excluding Rural People from Protected Forests: Spatial Resource Degradation and Rural Welfare
This paper examines how forest-dependent villagers meet a resource requirement when they are excluded from some area of a forest. Forest managers who value both pristine and degraded forest should take into account a .displacement effect. resulting in more intensive villager extraction elsewhere, and a .replacement effect. in which villagers purchase more of the resource from the market. Similarly, forest managers who have poverty concerns should recognize that exclusion zones tend to be more costly to villagers without market access and those with low opportunity costs of labour- typically the poorest villagers.
Readability, presentation and quality of allergy-related patient information leaflets: a cross sectional and longitudinal study
Objective: Patient information leaflets (PILs) are widely used to reinforce or illustrate health information and to complement verbal consultation. The objectives of the study were to assess the readability and presentation of PILs published by Allergy UK, and to conduct a longitudinal assessment to evaluate the impact of leaflet amendment and revision on readability. Methods: Readability of Allergy UK leaflets available in 2013 was assessed using Simple Measure of Gobbledegook (SMOG) and Flesch-Kincaid Reading Grade Formula. Leaflet presentation was evaluated using the Clear Print Guidelines of the Royal National Institute of Blind People (RNIB) and the Patient Information Appraisal System developed by the British Medical Association (BMA). Changes in the leaflets’ readability scores over five years were investigated. Results: 108 leaflets, covering a wide range of allergic conditions and treatment options, were assessed. The leaflets had average SMOG and Flesch-Kincaid scores of 13.9 (range 11-18, SD 1.2) and 10.9 (range 5-17, SD 2.1) respectively. All leaflets met the RNIB Clear Print guidelines, with the exception of font size which was universally inadequate. The leaflets scored on average 10 (median 10, range 7-15) out of a maximum of 27 on the BMA checklist. The overall average SMOG score of 31 leaflets available in both 2008 and 2013 had not changed significantly. The process of leaflet revision resulted in 1% change in readability scores overall, with a predominantly upward trend with six leaflets increasing their readability score by >10% and only three decreasing by >10%. Conclusion: Allergy-related patient information leaflets are well presented but have readability levels that are higher than those recommended for health information. Involving service users in the process of leaflet design, together with systematic pre-publication screening of readability would enhance the accessibility and comprehensibility of written information for people with allergy and their careers
Consensual Qualitative Research: An Update
The authors reviewed the application of consensual qualitative research (CQR) in 27 studies published since the method’s introduction to the field in 1997 by C. E. Hill, B. J. Thompson, and E. N. Williams (1997). After first describing the core components and the philosophical underpinnings of CQR, the authors examined how it has been applied in terms of the consensus process, biases, research teams, data collection, data analysis, and writing up the results and discussion sections of articles. On the basis of problems that have arisen in each of these areas, the authors made recommendations for modifications of the method. The authors concluded that CQR is a viable qualitative method and suggest several ideas for research on the method itself
Mental Health and Negative Sexual Experiences of Bahamian University Students
This study investigates the mental health of victims of sexual abuse, particularly rape, in college student populations. The study identifies the connection between sexual abuse/rape and elevated scores of mental health. It indicates that even with other stressful events occurring in the lives of respondents, sexual abuse/rape has a detrimental effect on the mental health of both males and females. A death in the family was the most commonly reported stressful event for males and females, and females were more likely than males to have suffered from a sexual attack. Early negative experiences of sexual intercourse can apparently have long lasting negative effects on the victim’s mental health. These findings require society to look beyond the physical consequences of sexual abuse and rape to ensure that the long-term mental health of victims, both male and female children and adults, is not overlooked
LATERALITY AND ITS EFFECT ON LOWER EXTREMITY MUSCULOSKELETAL STIFFNESS IN MALE SOCCER PLAYERS AND TRACK RUNNERS
The purpose of this study was to determine the influence of laterality on lower extremity stiffness in healthy soccer players and track runners. Eight soccer players aged 15 to 17
years, and eight track runners, aged from 18 to 25 years performed a battery of tests (Single and double legged continuous straight and bent-legged jumping, and running) to
determine lower extremity musculoskeletal stiffness. All participants were injury free at the time of testing. Statistical tests of the various all kinetic measures revealed that the
track runners were asymmetrical in their musculoskeletal performance qualities, whereas, the soccer players displayed symmetry. Future research should examine lower extremity
symmetry in an older group of soccer players, and the development of a training program to alter lower extremity stiffness into a typical range
EVALUATING STRENGTH QUALITIES OF ATHLETES USING RELATIONSHIPS BETWEEN JUMP PROTOCOLS
Understanding the relationships between jump assessments may provide information of an athlete’s strength qualities. Elastic Utilisation Ratio (EUR) is calculated between
countermovement jump (CMJ) and squat jump (SQJ) height, and is suggested to describe the stretch-shortening cycle ability of an athlete. Yet, knowledge of what constitutes a typical EUR range for an athlete remains unclear. The purpose of this study was to assess jump performance and the EUR of athletes from two sports (soccer and distance runners) using a portable forceplate. SQJ and CMJ heights were highly correlated (r>.90). Linear regression and standard error of estimate statistics were then used to estimate CMJ height and derive an expected EUR range. It was concluded, those athletes outside this predicted EUR range would benefit from specific training
BATF Regulates the Development and Function of IL-17 Producing iNKT Cells.
Background
BATF plays important roles in the function of the immune system. Batf null mice are deficient in both CD4+ Th17 cells and T follicular helper cells and possess an intrinsic B cell defect that leads to the complete absence of class switched Ig. In this study, Tg mice overexpressing BATF in T cells were used together with Batf null mice to investigate how altering levels of BATF expression in T cells impacts the development and function of a recently characterized population of iNKT cells expressing IL-17 (iNKT-17). Results
BATF has a direct impact on IL-17 expression by iNKT cells. However, in contrast to the Th17 lineage where BATF activates IL-17 expression and leads to the expansion of the lineage, BATF overexpression restricts overall iNKT cell numbers while skewing the compartment in vivo and in vitro toward an iNKT-17 phenotype. Conclusions
This work is the first to demonstrate that BATF joins RORÎłt as the molecular signature for all IL-17 producing cells in vivo and identifies BATF as a component of the nuclear protein network that could be targeted to regulate IL-17-mediated disease. Interestingly, these studies also reveal that while the Il17a gene is a common target for BATF regulation in Th17 and iNKT-17 cells, this regulation is accompanied by opposite effects on the growth and expansion of these two cell lineages
NOVEL INSIGHTS ON LOWER LIMB MUSCULOSKELETAL HEALTH AND PERFORMANCE IN PRE-ADOLESCENT AND ADOLESCENT GYMNASTS
New analyses are presented from the data of Bradshaw and Le Rossignol (2004) to examine the relationship between musculoskeletal health, and physical and performance qualities, with measures of leg stiffness in a group of female gymnasts. A gymnasts leg stiffness can be assessed through continuous jump (straight & bent legged) series tests, as well as from rebound jumps. Although the observations are retrospective, the study revealed a potential safe zone for ankle extensor stiffness. The gymnast with low stiffness had previously suffered a landing ankle injury; whilst four gymnasts with high stiffness had histories of take-off ankle injuries. Aside from profiling physical performance qualities, biomechanical (kinetic) testing has the potential to also aid in the assessment and management of the athlete’s functional musculoskeletal health (rehabilitation, injury risk)
HUNK phosphorylates EGFR to regulate breast cancer metastasis
Epidermal growth factor receptor (EGFR) is commonly over-expressed in metastatic breast cancer yet metastatic breast cancer is generally resistant to anti-EGFR therapies, and the mechanism for resistance to EGFR inhibitors in this setting is not fully understood. Hormonally up-regulated neu-associated kinase (HUNK) kinase is up-regulated in aggressive breast cancers and is thought to play a role in breast cancer metastasis. However, no studies have been conducted to examine a relationship between EGFR and HUNK in breast cancer metastasis. We performed a kinase substrate screen and identified that EGFR is phosphorylated by HUNK. Our studies show that HUNK phosphorylates EGFR at T654, enhancing receptor stability and downstream signaling. We found that increased phosphorylation of T654 EGFR correlates with increased epithelial to mesenchymal, migration and invasion, and metastasis. In addition, we found that HUNK expression correlates with overall survival and distant metastasis free survival. This study shows that HUNK directly phosphorylates EGFR at T654 to promote metastasis and is the first study to show that the phosphorylation of this site in EGFR regulates metastasis
