Optimized identification of fecal pollution sources in a rural tidal watershed in coastal New Hampshire

Escherichia coli ribotyping was used to identify fecal contamination sources in Grommet Creek- a tidal creek that drains into Great Bay and contaminates shellfishing beds. Water samples were collected during late summer through late fall. Fecal samples were collected to establish a local source species database. Fecal indicator bacteria were enumerated from water samples and ribotyping was conducted by using EcoR1 restriction enzyme digestion and an automated RiboPrinter(c). There was consistent relative abundance between source types with wild animals and birds as the primary sources. An optimized approach for maximizing source identification involved using a 90% similarity threshold and prioritizing the first (local) database, then the second (larger area), and the third (regional) database for source identification. Using this approach, 67% of the E. coli water sample isolates were identified to sources, mainly as geese, deer, and fox, suggesting that diminishing of these sources could improve water quality

Stylistics Analysis of Sylvia Plath’s Poem Poppies in October

Paper under view intends to evaluate Sylvia Plath’s poem Poppies in October (1962) from the perspective of stylistic analysis. It is carried out on Graphlogical, Morphological, Syntactical and Phonological levels. The poem is a blend of classicism with modernism; imagery, images, colours, irony and symbolism being chief features of the poem. This study is ready to lend a hand to examine the structure and style of Sylvia Plath’s poetry, her themes, style, and natural treatment. Keywords: Stylistics, nature, poppies, red, death

Characterization of age-related microstructural changes in locus coeruleus and substantia nigra pars compacta.

Locus coeruleus (LC) and substantia nigra pars compacta (SNpc) degrade with normal aging, but not much is known regarding how these changes manifest in MRI images, or whether these markers predict aspects of cognition. Here, we use high-resolution diffusion-weighted MRI to investigate microstructural and compositional changes in LC and SNpc in young and older adult cohorts, as well as their relationship with cognition. In LC, the older cohort exhibited a significant reduction in mean and radial diffusivity, but a significant increase in fractional anisotropy compared with the young cohort. We observed a significant correlation between the decrease in LC mean, axial, and radial diffusivities and measures examining cognition (Rey Auditory Verbal Learning Test delayed recall) in the older adult cohort. This observation suggests that LC is involved in retaining cognitive abilities. In addition, we observed that iron deposition in SNpc occurs early in life and continues during normal aging

Library Anxiety among Undergraduate Students: A case study of faculty of Management Science, University of Peshawar

Library anxiety is a psychological barrier to the academic performance of university students. This study was conducted among undergraduate students at the faculty of management sciences, the University of Peshawar to examine the factors which predict library anxiety. Library anxiety is a psychological barrier to academic success among college students. This study of 843 undergraduate team was administered by hand to all the sample size among university students in order to examine factors that predict library anxiety, a sample size of 262 was drawn 244 questionnaires was collected with a response rate of 93.12% based on Krejcie and Morgan’s (1970) table of sample size determination. The results indicate that the students were more anxious about the staff of the library than other factors. Thus it can be inferred that the attitude of library staff made a significant contribution to the degree of library anxiety among students which made them unable to effectively utilize library resources and services. Such behavior also contributed to other areas of library anxiety-like non-use or avoidance of the library by students, which results in achieving poor academic grades

A Simple and Cost-Effective EPON-Based Next Generation Mobile Backhaul RAN Architecture

This study proposes a novel, simple and cost-effective PON-based next generation mobile backhaul RAN architecture that enables redistribution of some of the intelligence currently centralized in the Mobile Packet Core (MPC) platform out into the access nodes of the RAN. Specifically, this work proposes a fully distributed ring-based EPON architecture that enables the support of a converged PON-4G/5G mobile WiMAX/LTE access networking transport infrastructure to seamlessly backhaul both mobile and wireline multimedia traffic and services

Walking the Talk? A Corporate Governance Perspective on Corporate Social Responsibility Decoupling

Information asymmetry and the pressure to conform to stakeholders’ expectations cause firms to engage in corporate social responsibility (CSR) decoupling – a practice that has severe socioeconomic consequences for firms. Adopting a corporate governance perspective, this paper answers a novel question: whether board gender diversity (BGD) curbs CSR decoupling. Using a battery of sophisticated analyses and robustness tests on 9276 firm-year observations for the period 2002–2017, our results confirm that BGD is negatively associated with CSR decoupling. Analysis of the composition of gender-diverse boards further reveals that this effect is stronger for balanced boards than for skewed and tilted boards. Furthermore, we note that independent female directors are more effective monitors of decoupling than executive female directors. We also document that the relationship between BGD and CSR decoupling is stronger when the overall governance is weak. This implies that gender-diverse boards could act as a substitute mechanism for corporate governance that would otherwise be weak. Our study offers important theoretical and policy implications for the field of corporate governance and CSR

Needs assessment for faculty development in health professions education at a medical university in Karachi, Pakistan

Faculty Development (FD) embraces all educational activities used by teachers to improve their knowledge and skills for enhancing their academic competencies. This study aimed to identify the areas in Health Professions Education (HPE) in which formal faculty development is required. A needs assessment survey was conducted from among the faculty members at the Aga Khan University (AKU), Karachi, Pakistan, and the French Medical Institute for Mother and Children, Afghanistan. Data was analysed using SPSS 20.0 and reported frequencies and percentages according to various academic tracks. Competency-based curricula (51%), providing effective feedback (51%), developing Objective Structured Clinical Exam (51%), and clinical supervision (48%) were identified as significant areas for faculty development. Faculty in clinician teacher and clinician educator track require advanced training, i.e., Masters and PhD in HPE. The needs assessment facilitated prioritising the areas for FD. This will contribute to enhancing academic practices and inculcating the culture of lifelong learnin

Wearable sensors for respiration monitoring: a review

This paper provides an overview of flexible and wearable respiration sensors with emphasis on their significance in healthcare applications. The paper classifies these sensors based on their operating frequency distinguishing between high-frequency sensors, which operate above 10 MHz, and low-frequency sensors, which operate below this level. The operating principles of breathing sensors as well as the materials and fabrication techniques employed in their design are addressed. The existing research highlights the need for robust and flexible materials to enable the development of reliable and comfortable sensors. Finally, the paper presents potential research directions and proposes research challenges in the field of flexible and wearable respiration sensors. By identifying emerging trends and gaps in knowledge, this review can encourage further advancements and innovation in the rapidly evolving domain of flexible and wearable sensors.This work was supported by the Spanish Government (MICINN) under Projects TED2021-131209B-I00 and PID2021-124288OB-I00.Peer ReviewedPostprint (published version
