An evaluation of organic matter dispersed in the Menilite Formation in Silesian Nappe (Polish Outer Carpathians): an optical microscopic approach

In this study, optical microscopic analyses were applied to evaluate the thermal maturity, characteristics of solid bitumen, and other organic matter finely dispersed in Oligocene shales of the Menilite Formation in the Iwonicz-Zdrój–Rudawka Rymanowska Fold (IRF) and Bóbrka–Rogi Fold (BRF) of the Central Carpathian Synclinorium of the Silesian Nappe, Outer Carpathians, Poland. The investigation was carried out at two-unit depths of the shallow and deeper D-1 sections (430 m – IRF and 4,300 m – BRF) and outcrop samples (BRF). The mean random huminite reflectance values indicate immature conditions with respect to hydrocarbon generation in samples from the D-1 shallow section (VRo≈0.40%) and in the outcrop samples (VRo=0.36%). The degree of thermal maturity of the organic matter from a depth of about 4,300 m – BRF based on random vitrinite (VRo≈0.80%) and solid bitumen (BRo≈0.65%) reflectance measurements is associated with the “oil window” for petroleum generation. The organic components dispersed in the examined Menilite Formation samples are typical for hydrocarbon-prone organic matter, suggesting the dominant kerogen type II. The potential precursor maceral for solid bitumen occurring in the examined samples from the deeper D-1 sections is largely the alginite maceral

Ordovician and Silurian Formations of the Baltic Syneclise (NE Poland): An Organic Geochemistry Approach

AbstractThe Baltic Syneclise is one of the Paleozoic basins along the western margin of the East European Craton. Commercial amounts of hydrocarbons have been found onshore and offshore in the Middle Cambrian sandstones and Upper Ordovician limestone reefs. The Middle-Upper Cambrian and Tremadocian bituminous shales have been identified as good quality effective source rocks. The existence of good quality source rocks in the Ordovician and Silurian profiles provides an impetus for conventional and unconventional hydrocarbon explorations in this region. Geochemical analyses revealed that the rocks of the Middle–Late Ordovician and Early Silurian horizons exhibit overall good to very good source rock quality. Within the Ordovician strata, the Sasino and Prabuty formations exhibit the highest amounts of organic carbon with the median total organic carbon (TOC) values of 1.96 and 1.23 wt. %, respectively. The Pasłęk and Pelplin formations in the lowest parts of the Lower Silurian stand out clearly from other formations with the median TOC values of 0.91 and 1.15 wt. % and median total hydrocarbon content (S1+S2) of 2.46 and 1.54 mg HC/g rock, respectively. The analyzed successions are dominated by immature/early mature, algal (oil-prone) type II, and mixed II/I kerogen deposited in a marine paleoenvironment with anoxic conditions at the bottom and oxic conditions in the photic zone. Immature organic matter prevails in the eastern and central parts of the study area (Gołdap–Kętrzyn–Olsztyn area), and the western part (Darżlubie–Hel–Gdańsk area) has mature kerogen

Demographic Differences in United States Consumers’ Perceptions and Willingness to Pay for Sustainable Environmental Practices in the Floral Industry

Consumers have become increasingly concerned about the environmental standards of industries from which they purchase products. Because consumers’ environmental concerns are increasingly becoming part of their purchasing decisions, industries have begun to restructure their business model to one that is more environmentally sustainable. Studies have indicated consumers’ actions and motivations for purchasing sustainable products vary based on consumer demographics. The main purpose of this study was to compare the differences in consumers’ perceptions and willingness to pay as they relate to retail floral providers’ sustainable and environmentally sound practices based on demographic traits. A total of 2172 people responded to an online survey. The sample used in this study was a random selection of individuals 18 years of age or older living in the United States. Survey responses were collected from 21 Dec 2022 to 27 Jan 2023. Data were analyzed using analyses of variance and post hoc tests as well as descriptive and frequency statistics. Results indicated there was a difference in the way respondents answered the survey questions based on demographics. Respondents 34 years of age or younger with college experience indicated the most willingness to make purchases and pay premiums from floral providers that incorporate sustainable attributes into their business model. Males indicated a stronger willingness to shop at a floral provider based on several of the environmental statements when compared with other genders. The results provide evidence of the value of the integration of sustainability practices into the business model of floral providers to make it more competitive

United States Consumers’ Perceptions and Willingness to Pay for Sustainable Environmental Practices in a Retail Floral Provider’s Business Model

Research suggests consumers are willing to pay a premium for goods from industries that design products using environmentally sound practices and that these practices lead to customer loyalty. Using environmentally friendly practices can differentiate a business from competitors through branding, which has been known to help increase profit margins and stimulate demand in a saturated market. The main purpose of this study was to gain an understanding of consumer perceptions and willingness to pay as they relate to retail floral providers’ sustainable and environmentally friendly practices. A total of 2172 people responded to an online survey. The sample used in this study was a random selection of individuals 18 years and older living in the United States. Survey responses were collected from 21 Dec 2022 to 27 Jan 2023. Respondents indicated the use of locally sourced flowers followed by the recycling of flower waste through composting as the two sustainable attributes that would increase their willingness to make purchases the most. Respondents indicated the strongest willingness to pay 10% or more for locally sourced flowers (61.7%), followed by flower providers composting their floral waste (59.5%). In addition, 50% or more of all respondents indicated a willingness to pay 10% or more for all the sustainable attributes for which they were asked. The methods in which retail floral providers source floral material, create floral designs, and market and brand their company are important considerations when promoting their services toward environmentally conscious consumers and in creating a valuable repeat customer base

Use of Gardening Programs as an Intervention to Increase Children’s Ability to Delay Gratification

The purpose of this study was to examine the ability of preschool gardening programs to help children develop their ability to delay gratification. Children today face many opportunities for instant gratification, although the ability to delay gratification in early childhood has been linked to numerous benefits later in life. Opportunities to train children in the ability to delay gratification present educational challenges, in that it competes with other academic training needs, and it can be difficult to find programs that are interesting to young children. The population for this study was preschool children ranging in age from 2 to 6 years, with treatment and control groups drawn from different schools. Participants were tested individually and timed to determine their ability to delay gratification, with promises of larger rewards if the child could wait for 15 minutes. The results of this study did not identify a significant change in all children’s ability to delay gratification after a gardening program. However, analyses showed that females appear to have responded more positively to the gardening treatment in their ability to delay gratification, whereas males in the control group benefited more from traditional school lessons

Effects of an Informal Place-based Educational Program on Knowledge and Perceptions of Invasive Species Management

Invasive species can generate negative impacts environmentally, socially, and economically. The interplay between human and natural systems renders management a complex problem that must be addressed by decision-makers. Perceptions of invasive species issues varies depending on an individual’s access to information. Although invasive species and their management are often discussed in formal higher education, not all members of the population have access to a formal educational setting. Informal educational experiences may be a mechanism to reach out to community members in a more accessible and perhaps engaging way than traditional higher education classroom experiences. The purpose of this study was to determine the effect of an informal, place-based educational program on perceptions and knowledge of invasive species and their management within the community. Place-based education is a pedagogy connection local places with intimate knowledge of the systems, processes, and outcomes that give it meaning to human and non-human species. First, we organized and administered short walks in two central Texas, USA, parks with conversational lessons and hands-on learning experiences. Second, we administered a follow-up retrospective-reflective survey to measure participants’ knowledge and perceptions of invasive species management and postwalk/lesson changes in them. We also compared between the treatment group of participants versus a control group within the community who did not participate in the informal lessons. Fifty-two people participated in both the educational program walks and testing over the course of 1 year, and 63 people were included in the follow-up retrospective-reflective survey control group. Results indicate a statistically significant positive change in knowledge and perception categories within the treatment group. Post hoc results indicate a positive change in knowledge and perceptions in our sample as a function of treatment group members’ age and income, respectively. The methodology used in this study was simple and inexpensive. Hence, our approach could be easily replicated in other areas to educate community members

The Connection between Gardening and Outdoor Activity during the COVID-19 Pandemic and Perceptions of Hope, Hopelessness, and Levels of Stress, Anxiety, and Depression

During the past few years, Americans have experienced a wide variety of stressors, including political tensions, racial/civil unrest, and the coronavirus disease 2019 (COVID-19) pandemic. All of these have led to uncertainty within society. Chronic feelings of helplessness can lead to depression or feelings of hopelessness in those who perceive their situation as unchanging. The purpose of this study was to evaluate the impacts of gardening and outdoor activities during the COVID-19 pandemic on perceptions of hope, hopelessness, and levels of depression, stress, and anxiety. Participants of this study were recruited through online social media platforms such as Facebook and Instagram; 458 participants completed the 21-item Depression Anxiety and Stress Scale inventory as well as the Hope Scale. Our data indicated that individuals who self-reported themselves as gardeners had significantly more positive scores related to levels of stress, anxiety, and depression and a sense of hope. Furthermore, gardeners had lower levels of self-reported depression, anxiety, and stress when compared with those who did not identify themselves as gardeners. The gardeners also had a more positive outlook regarding hope for the future. Additionally, a significant positive correlation was found between the number of hours spent participating in gardening and a sense of hope, and a negative correlation was found between the number of hours gardening and stress levels. Similarly, there was a significant negative correlation between the number of hours spent participating in any outdoor activity and self-reported levels of stress, anxiety, or depression; however, there was a positive correlation between the number of hours spent participating in any outdoor activity and a sense of hope. Our data suggested that more hours spent outside gardening or participating in recreational activities led to less perceived stress, anxiety, and depression and greater levels of hope for the future

The influence of glycation on a high pressure denaturation of ubiquitin

Synopsis The combination of deuterium-hydrogen exchange (DHX) and mass spectrometry (MS) can be used for studying a high pressure denaturation (HPD) of proteins. Herein we present the results of investigations of the influence of glycation on the HPD of ubiquitin. Application of various values of pressure causes different degrees of protein unfolding, resulting in molecules with a different number of protons available for exchange with deuterons. The dependence of this number on pressure gives information on the denaturation state of a protein. On the basis of the obtained results we can conclude that increasing number of fructosamine moieties in ubiquitin decreases the pressure required for its denaturation. It suggests that glycation moderately decreases the protein stability. The present study is the first example of application of hydrogen-deuterium exchange as a method of investigating the influence of posttranslational modification of protein on the HPD
