The Impact of Pubertal Timing and Physical Characteristics

Objectives, Purpose, or Aim: This article investigates whether the physical environment in which childbirth occurs impacts the intrapartum intervention rates and how this might happen. The study explores the spatial physical characteristics that can support the design of spaces to promote the health and well-being of women, their supporters, and maternity care professionals. Background: Medical interventions during childbirth have consequences for the health of women and babies in the immediate and long term. The increase in interventions is multifactorial and may be influenced by the model of care adopted, the relationships between caregivers and the organizational culture, which is made up of many factors, including the built environment. In the field of birth architecture research, there is a gap in the description of the physical characteristics of birth environments that impact users’ health. Method: A scoping review on the topic was performed to understand the direct and indirect impacts of the physical environment on birth intervention rates. Results and Discussion: The findings are organized into three tables reporting the influence that the physical characteristics of a space might have on people’s behaviors, experiences, practices and birth health outcomes. Eight building spaces that require further investigation and research were highlighted: unit layout configuration, midwives’ hub/desk, social room, birth philosophy vectors, configuration of the birth room, size and shape of the birth room, filter, and sensory elements. Conclusions: The findings show the importance of considering the physical environment in maternity care and that further interdisciplinary studies focused on architectural design are needed to enrich the knowledge and evidence on this topic and to develop accurate recommendations for designers.

The Impact

The applicability of utilizing a variety of thermal mass including phase change materials with commonly used building materials is investigated through the use of simulations and physical testing. The thermal performance and occupant comfort potential of a novel solid-solid phase change material, known as Dal HSM, is compared and contrasted to commonly available forms of thermal mass. Detailed experimentation is conducted to successfully integrate Dal HSM with gypsum and concrete. The measurement of physical characteristics such as compressive strength and modulus of rupture is conducted to ensure that the PCM-composite compound retains the structural integrity to be utilized in a typical building. The use of thermal mass in the Toronto Net Zero house was found to contribute to energy savings of 10-15% when different types of thermal mass were used. The comfort level of the indoor occupants was also found to increase. The performance of Dal HSM was found to be comparable to a commercially available PCM known as Micronal in the heating mode. The cooling mode revealed that Dal HSM provided slightly lower energy savings when compared to Micronal due to a lower phase transition temperature and latent heat. The performance of physical test revealed a decrease in the compressive strength as the concentration of Dal HSM was increased in the PCM-gypsum specimens. Tests were also performed to analyze the impact of increasing the PCM concentration on the flexural strength of PCM-gypsum composite.

The Impact

ABSTRACT In search of a more sustainable agriculture, the use of beneficial microorganisms has been highlighted, because they are low-cost and can reduce the use of fertilizers and increase grain yield. The present study aimed to evaluate the efficiency of A. brasilense inoculation and the best form and dose of inoculation in maize, measuring the impact on some physical characteristics and on its nutrition. The experiment was conducted in a greenhouse, in Ilha Solteira, SP, Brazil, in a completely randomized design, with four replicates and eight treatments: 1) control; 2) Seed 1x; 3) Seed 2x; 4) Soil 1x; 5) Soil 2x; 6) Leaf 1x; 7) Leaf 2x; 8) Seed 1x + Leaf 1x, respectively representing in each treatment the site and dose of application (1x, dose recommended by the manufacturer; 2x, twice the dose recommended by the manufacturer). No differences were found in any physical characteristics evaluated between treatments; however, for nutrient contents in the leaf tissue, there was effect on Zn content. It was concluded that, regardless of the presence of A. brasilense inoculation, forms or dose (in hybrid DKB 350), in general, there were no improvements in the characteristics evaluated.

The Impact

Abstract Twenty-seven public timber tracts were auctioned in Minnesota where bidders were required to submit two sealed bids for a tract–one with and the other without the use of timber harvesting guidelines. After the auctions, bidders were mailed a questionnaire requesting information about their logging business, the sources of information consulted in developing their bids, and perceptions of how various tract- and sale-specific factors and guidelines influenced their bidding behavior. The majority of responding timber harvesters did not consult any special sources and only one-half visited the tract before submitting their bids. Although bidding behavior was influenced by several factors, a tract's physical characteristics (e.g., volume of merchantable timber) had a greater influence on their bidding behavior than did any guidelines. Of the guidelines evaluated, those that required leaving merchantable trees (e.g., for wildlife or visual purposes) were reported to have the greatest influence on stumpage bids. Sale-specific variables (e.g., timber harvester's need for timber) had only a minimal to moderate influence on bidding behavior. The findings suggest that timber sale design can help mitigate the cost associated with implementing forest management guidelines.North. J. Appl. For. 22(4):275–280.

Practical Implications

This article examines whether and why organizing product categories according to the consumption goal they serve (i.e., complement-based assortment organization) may increase purchases compared with organizing product categories according to their attributes or physical characteristics (i.e., substitute-based assortment organization). Across two field experiments, a virtual reality experiment, and a lab experiment, the authors show that a complement-based assortment organization, compared with a substitute-based assortment organization, leads to increased numbers of purchases and increased expenditures. Ease of visualization of the consumption process mediates the results. The impact of the complement-based organization on purchases is more pronounced for less involved consumers and for consumers with a less specific shopping goal. These findings have both theoretical and practical implications.

The Impact

From the earliest stages of Greek thought, sound was thought to originate as the result of an impact between two objects. At first it was believed that the swiftness and force of the impact affected both volume and pitch; then it became clear that these were two different parameters. Pitch, in particular, was connected either to quantitative factors, such as the speed of the movement or the number of subsequent impacts, or to qualitative ones, like the idiotes (“peculiarity”) theorized by Theophrastus. The least investigated parameter of sound is timbre, which was usually attributed to the physical characteristics of the source.

The main theme of this work was to find out the impact on present status of improved traditional culture and mixed culture in various pond. This study involved the observations made on physical characteristics, ownerships system, ponds preparation, stocking combinations of fish seeds, post stocking management and maintenance, harvesting and cost analysis of 16 improved traditional managed ponds in Rajshahi City Corporation. The primary data for the study was taken from the growers of these ponds. After collecting primary data, it was analyzed by suitable statistical method. Physical characteristics of the sampling pond were found. Water depth more or less sufficient, water colour greenish, presence of sunlight was sufficient, water source was mainly drain and rain and various shaped of pond was found. Pond was prepared by traditional method using pesticides (Phostoxin, Rotanone, Sumithion, Quick fume), lime and fertilizers (Urea, TSP., Cow dung). The fish seed were stocked in different ponds. In Sac fry was stocked in 4 nursery ponds. Post stocking management and maintenance were included inorganic fertilizer (Urea, TSP), organic fertilizer cow dung, applied weekly and supplementary feeds were used daily. It was observed that 15 ponds were made profit and one pond had loss. Two types of ownership were found (three years and five years) in the study period. During the study time two types of harvesting method were found. They were partial and final harvest. Mainly two types of production cost such as variable cost (lease, pond preparation, pesticide use, fertilizer etc.) and fixed cost (cost of net, net preservation, tax of pond etc.) were observed in the study period.Asian J.

Age Discrepancy

Abstract Context Children with brain tumors may have pubertal onset at an inappropriately young chronologic age. Hypothalamic-pituitary irradiation ≥18Gy has been found to be a risk factor; age at irradiation is associated with pubertal timing. However, the underlying mechanisms are unknown. Objective To determine the impact of body mass index (BMI) and catch-up growth on pubertal timing in females treated for medulloblastoma and other embryonal tumors. Design, Setting, and Patients Retrospective cohort analysis of 90 female patients treated for medulloblastoma and other embryonal tumors at Dana-Farber Cancer Institute/Boston Children’s Hospital from 1996 to 2016. Eighteen individuals met inclusion criteria, with a mean ± SD follow-up period of 11.9 ± 3.4 years. Main Outcome Measures Multiple linear regression models for age at pubertal onset and bone age discrepancy from chronologic age at pubertal onset assessed the joint influences of age at irradiation, hypothalamic irradiation dose, undernutrition duration, BMI standard deviation score (SDS) at pubertal onset, and catch-up BMI SDS. Results The mean ± SD age of pubertal onset was 9.2 ± 1.3 years and hypothalamic radiation dose was 31.9 ± 9.9 Gy. There was a direct relationship between age at irradiation and age at pubertal onset (β = 0.323 ± 0.144 [standard error] year per year; P = 0.04) that was significantly attenuated after adjusting for BMI SDS at pubertal onset (P = 0.5) and catch-up BMI SDS (P = 0.08), suggesting that BMI is a mediator. Conclusions Both absolute and catch-up BMI SDS at pubertal onset are significant mediators of pubertal timing and bone age discrepancy in pediatric medulloblastoma and other embryonal tumors, and thus, are targetable risk factors to optimize pubertal timing.
