Public Perceptions of the Nonprofit Sector
In our economy there are three different sectors, (1) the government, (2) for-profit business, and (3) nonprofit organizations. Nonprofits are businesses which do not earn money/return profits for their owner(s) but instead direct all their funds towards a certain cause. Nonprofit organizations are generally recognized by the public, however, as charitable entities organized to meet community needs through the use of donated volunteer time and money. As a result of this general perception of the nonprofit sector, many people believe nonprofits do not require profit or a large overhead net to accomplish their mission. Profit and overhead costs, however, are essential for organizational effectiveness and growth to happen. Therefore, public awareness regarding these misconceptions must be addressed. By reviewing research about public perceptions of the nonprofit sector, and attending the Montana Nonprofit Association annual conference, this research study discusses the general public’s confusion associated with nonprofit organizations and highlights three suggestions on altering current public perceptions. The three suggestions are (1) changing the name nonprofit organization to a more mutual/less confusing name, (2) implementing business-like features into nonprofit organizations’ operations, and (3) enacting public education through different forms of communication. This study used an anonymous and voluntary survey to see which of the three suggestions the Missoula community best responded to. This research study exhibits the data from the survey and discusses the results as a conclusion. Local nonprofit organizations can utilize this information to benefit their organization in becoming more efficient businesses because they will have direct information coming from their community
Recent Progress in the Application of Transition-Metal Containing MFI topologies for NH₃-SCR-DeNOₓ and NH₃ oxidation
Transition metal-containing MFI-based catalysts are widely investigated in the selective catalytic reduction of NOx with ammonia (NH3-SCR-DeNOx), and the selective catalytic oxidation of ammonia (NH3-SCO) into nitrogen and water vapor. While MFI-based catalysts are less intensively studied than smaller pore zeolites (i. e., chabazite, CHA) they are still used commercially for these processes and are of great interest for future study in particular to better understand structure-activity relationships. Hierarchically porous MFI catalysts (containing both micropores and mesopores) often show enhanced catalytic properties compared to conventional (microporous) materials in both NH3-SCR-DeNOx and NH3-SCO. Thus, a critical overview of the current understanding of the salient physico-chemical properties that influence the performance of these catalysts is examined. Furthermore, strategies for the development of ZSM-5 based catalysts with enhanced catalytic lifetime, supported by the investigations of reaction mechanisms are reviewed and discussed
Derivation of the formyl-group oxygen of chlorophyll b from molecular oxygen in greening leaves of a higher plant (Zea mays)
Using mass spectroscopy, we demonstrate as much as 93% enrichment of the 7-formyl group oxygen of chlorophyll b when dark-grown, etiolated maize leaves are greened under white light in the presence of 18O2. This suggests that a mono-oxygenase is involved in the oxidation of its methyl group precursor. The concomitant enrichment of about 75% of the 131-oxygen confirms the well-documented finding that this oxo group, in both chlorophyll a and b, also arises from O2. High 18O enrichment into the 7-formyl oxygen relative to the substrate 18O2 was achieved by optimization of the greening conditions in combination with a reductive extraction procedure. It indicates not only a single pathway for Chl b formyl group formation, but also unequivocally demonstrates that molecular oxygen is the sole precursor of the 7-formyl oxygen
A rapid review and meta-analysis of the asymptomatic proportion of PCR-confirmed SARS-CoV-2 infections in community settings [version 1; peer review: awaiting peer review]
Background: Cross-sectional studies indicate that up to 80% of active SARS-CoV-2 infections may be asymptomatic. However, accurate estimates of the asymptomatic proportion require systematic detection and follow-up to differentiate between truly asymptomatic and pre-symptomatic cases. We conducted a rapid review and meta-analysis of the asymptomatic proportion of PCR-confirmed SARS-CoV-2 infections based on methodologically appropriate studies in community settings. /
Methods: We searched Medline and EMBASE for peer-reviewed articles, and BioRxiv and MedRxiv for pre-prints published before 25/08/2020. We included studies based in community settings that involved systematic PCR testing on participants and follow-up symptom monitoring regardless of symptom status. We extracted data on study characteristics, frequencies of PCR-confirmed infections by symptom status, and (if available) cycle threshold/genome copy number values and/or duration of viral shedding by symptom status, and age of asymptomatic versus (pre)symptomatic cases. We computed estimates of the asymptomatic proportion and 95% confidence intervals for each study and overall using random effect meta-analysis. /
Results: We screened 1138 studies and included 21. The pooled asymptomatic proportion of SARS-CoV-2 infections was 23% (95% CI 16%-30%). When stratified by testing context, the asymptomatic proportion ranged from 6% (95% CI 0-17%) for household contacts to 47% (95% CI 21-75%) for non-outbreak point prevalence surveys with follow-up symptom monitoring. Estimates of viral load and duration of viral shedding appeared to be similar for asymptomatic and symptomatic cases based on available data, though detailed reporting of viral load and natural history of viral shedding by symptom status were limited. Evidence into the relationship between age and symptom status was inconclusive. /
Conclusion: Asymptomatic viral shedding comprises a substantial minority of SARS-CoV-2 infections when estimated using methodologically appropriate studies. Further investigation into variation in the asymptomatic proportion by testing context, the degree and duration of infectiousness for asymptomatic infections, and demographic predictors of symptom status are warranted
Council tax valuation bands, socio-economic status and health outcome: a cross-sectional analysis from the Caerphilly Health and Social Needs Study
Council tax valuation bands (CTVBs) are a categorisation of household property value in Great Britain. The aim of the study was to assess the CTVB as a measure of socio-economic status by comparing the strength of the associations between selected health and lifestyle outcomes and CTVBs with two measures of socio-economic status: the National Statistics Socio-Economic Classification (NS-SEC) and the 2001 UK census-based Townsend deprivation index. METHODS: Cross-sectional analysis of data on 12,092 respondents (adjusted response 62.7%) to the Caerphilly Health and Social Needs Study, a postal questionnaire survey undertaken in Caerphilly county borough, south-east Wales, UK. The CTVB was assigned to each individual by matching the sampling frame to the local authority council tax register. Crude and age-gender adjusted odds ratios for each category of CTVB, NS-SEC and fifth of the ward distribution of Townsend scores were estimated for smoking, poor diet, obesity, and limiting long-term illness using logistic regression. Mean mental (MCS) and physical (PCS) component summary scores of the Short-Form SF-36 health status questionnaire were estimated in general linear models. RESULTS: There were significant trends in odds ratios across the CTVB categories for all outcomes, most marked for smoking and mental and physical health status. The adjusted odds ratio for being a smoker in the lowest versus highest CTVB category was 3.80 (95% CI: 3.06, 4.71), compared to 3.00 (95% CI: 2.30, 3.90) for the NS-SEC 'never worked and long-term unemployed' versus 'higher managerial and professional' categories, and 1.61 (95% CI: 1.42, 1.83) for the most deprived versus the least deprived Townsend fifth. The difference in adjusted mean MCS scores was 5.9 points on the scale for CTVB, 9.2 for NS-SEC and 3.2 for the Townsend score. The values for the adjusted mean PCS scores were 6.3 points for CTVB, 11.3 for NS-SEC, and 2.5 for the Townsend score. CONCLUSION: CTVBs assigned to individuals were strongly associated with the health and lifestyle outcomes modelled in this study. CTVBs are readily available for all residential properties and deserve further consideration as a proxy for socio-economic status in epidemiological studies in Great Britain
Was He Guilty as Charged? An Alternative Narrative Based on the Circumstantial Evidence from \u3cem\u3e12 Angry Men\u3c/em\u3e
This essay argues that while 12 Angry Men is typically viewed as a vindication of innocence, careful consideration of the evidence suggests that the jury probably reached the wrong verdict: the circumstantial evidence pointed to guilt! The authors use this insight to discuss the potential impact of circumstantial versus direct evidence on real juries and perhaps the ways that cases are litigated. The essay suggests a number of questions requiring empirical research
