Influence of nutrient enrichment on temporal and spatial dynamics of dissolved oxygen within northern temperate estuaries

In temperate estuaries of the southern Gulf of St. Lawrence, intermittent seasonal anoxia coupled with phytoplankton blooms is a regular occurrence in watersheds dominated by agricultural land use. To examine the spatial relationship between dissolved oxygen and phytoplankton throughout the estuary to assist in designing monitoring programs, oxygen depth profiles and chlorophyll measurements were taken bi-weekly from May to December in 18 estuaries. In five of those estuaries, dissolved oxygen data loggers were set to measure oxygen at hourly intervals and at multiple locations within the estuary the subsequent year. The primary hypothesis was that dissolved oxygen in the upper estuary (first 10% of estuary area) is predictive of dissolved oxygen mid-estuary (50% of estuary area). The second hypothesis was that hypoxia/superoxia in the estuary is influenced by temperature and tidal flushing. Oxygen depth profiles conducted in the first year of study provided preliminary support that dissolved oxygen in the upper estuary was related to dissolved oxygen throughout the estuary. However, dissolved oxygen from loggers deployed at 10% and 50% of estuary area did not show as strong a correlation as expected (less than half the variance explained). The strength of the correlation declined towards the end of summer. Spatial decoupling of oxygen within the estuary suggested influence of local conditions. Chlorophyll concentration seemed also to be dependent on local conditions as it appeared to be coupled with the presence of sustained anoxia in the upper estuary with blooms typically occurring within 7 to 14 days of anoxia. The practical implication for oxygen monitoring is that one location within the most severely impacted part of the estuary is not sufficient to fully evaluate the severity of eutrophication effects.

Multiple Variable Social Distancing Model in Reducing COVID 19 Spreading: A Long Term Social Distancing Model in Developing Nations Like Bangladesh

Covid-19 pandemic requires strong and inclusive social distancing policies for the people. Governments around the world have taken policy steps and citizen were expected to behave accordingly. However, Countries like Bangladesh faced enormous difficulties and challenges to make people understand and obey them. There is variety of groups in the society among whom a few were respectful and some were negligent towards those social distancing policies. This study tried to find what makes them obey or disobey the prescribed pandemic behavior. This research found people over-confident, religiously blind, economically bound, poorly educated, doubtful to their government, impatient about the time frame of the lockdown and social distancing rules and so on. Additionally, sometimes government policies were proved to be incompatible with the rising situation.   Primary hypothesis of this study is, ``willingness of social distancing is a dependent variable where over-confidence, education, poverty, religion, public trusts are independent variables. Taking general policies like other natural disaster or calamities may not be as effective as it was before.’’ This pandemic is an event which needs an in-depth research, wider policy analysis and firm implementation. Here is a suggestion called `multiple variable social distancing model' which will study about the variables first and guide to a wider policy structure afterwards.

Sexual Dysfunction and Gun Ownership in America: When Hard Data Meet a Limp Theory

Although there has been no direct empirical evidence linking sexual dysfunction (SD) with gun ownership, speculation has been widespread and persistent for decades. In this paper, we formally examine the association between SD and gun ownership. Our primary hypothesis, derived from the psychosexual theory of gun ownership, asserts that men experiencing SD are more likely to personally own guns than other men. To test this hypothesis, we used recently collected data from the 2021 Crime, Health, and Politics Survey (CHAPS), a national probability sample of 780 men, and binary logistic regression to model gun ownership as a function of SD. Our key finding is that men experiencing SD are no more likely to own guns than men without SD. This interpretation was supported across several indicators of SD (performance anxiety, erection trouble, and ED medication) and gun ownership (personal gun ownership, purchasing a gun during the pandemic, and keeping a gun in one’s bedroom). To our knowledge, we are the first to have directly tested the association between SD and gun ownership in America. Our findings are important because they contribute to our understanding of factors associated with gun ownership by challenging the belief that phallic symbolism and masculinity somehow drive men with SD to purchase guns. Our results also remind us of the perils of gun culture rhetoric, which, in this case, function to discredit gun owners and to further stigmatize men with ED. We conclude by calling for more evidence-based discussions of SD and guns in society.

Comparing Behavioral and Emotional Strengths of Students With and Without Emotional Disturbance

The present study investigated evidence of the construct validity of scores from the Behavioral and Emotional Rating Scale (BERS-3), which is a multi-informant assessment designed to measure the behavioral and emotional strengths of school-aged youth. The purpose of this research was to evaluate the degree to which BERS-3 scores differed between students with school-identified emotional disturbance and students without disabilities. Two nationally representative samples were used in this study: (a) 1,575 students rated by teachers and (b) 793 youth who provided self-ratings. The results of multivariate multiple regression analyses supported the primary hypothesis that students with emotional disturbance would have lower scores on each of the five BERS-3 subscale scores compared to peers without disabilities. This finding held for both samples; however, differences between students with emotional disturbance and the peers without disabilities were substantially smaller for the youth self-ratings compared to teacher ratings. Implications for practice and directions for future research are also discussed.

COVID-19 infection and subsequent psychiatric morbidity, sleep problems and fatigue: analysis of an English primary care cohort of 226,521 positive patients

Objectives The primary hypothesis was that the risk of incident or repeat psychiatric illness, fatigue and sleep problems increased following COVID-19 infection. The analysis plan was pre-registered (https://osf.io/n2k34/). Design Matched cohorts were assembled using a UK primary care registry (the CPRD-Aurum database). Patients were followed-up for up to 10 months, from 1st February 2020 to 9th December 2020. Setting Primary care database of 11,923,499 adults (>16 years). Participants From 232,780 adults with a positive COVID-19 test (after excluding those with <2 years historical data or <1 week follow-up), 86,922 without prior mental illness, 19,020 with anxiety or depression, 1,036 with psychosis, 4,152 with fatigue and 4,539 with sleep problems were matched to up to four controls based on gender, general practice and year of birth. A negative control used patients who tested negative for COVID-19 and patients negative for COVID with an influenza diagnosis. Main Outcomes and Measures Cox proportional hazard models estimated the association between a COVID-19 positive test and subsequent psychiatric morbidity (depression, anxiety, psychosis, or self-harm), sleep problems, fatigue or psychotropic prescribing. Models adjusted for comorbidities, ethnicity, smoking and BMI. Results After adjusting for observed confounders, there was an association between testing positive for COVID-19 and almost all markers of psychiatric morbidity, fatigue and sleep problems. The adjusted hazard ratio (aHR) for incident psychiatric morbidity was 1.75 (95% CI 1.56-1.96). However, there was a similar risk of incident psychiatric morbidity for those with a negative COVID-19 test (aHR 1.57, 95% CI 1.51-1.63) and a larger increase associated with influenza (aHR 2.97, 95% CI 1.36-6.48). Conclusions There is consistent evidence that COVID-19 infection elevates risk of fatigue and sleep problems, however the results from the negative control analysis suggests that residual confounding may be responsible for at least some of the association between COVID-19 and psychiatric morbidity.

Video-assisted cardiopulmonary resuscitation: Does the camera perspective matter? A randomized, controlled simulation trial

Background Dispatcher assistance can help to save lives during layperson cardiopulmonary resuscitation during cardiac arrest. The aim of this study was to investigate the influence of different camera positions on the evaluation of cardiopulmonary resuscitation performance during video-assisted cardiopulmonary resuscitation. Methods For this randomized, controlled simulation trial, seven video sequences of cardiopulmonary resuscitation performance were recorded from three different camera positions: side, foot and head position. Video sequences showed either correct cardiopulmonary resuscitation performance or one of the six typical errors: low and high compression rate, superficial and increased compression depth, wrong hand position or incomplete release. Video sequences with different cardiopulmonary resuscitation performances and camera positions were randomly combined such that each evaluator was presented seven individual combinations of cardiopulmonary resuscitation and camera position and evaluated each cardiopulmonary resuscitation performance once. A total of 46 paramedics and 47 emergency physicians evaluated seven video sequences of cardiopulmonary resuscitation performance from different camera positions. The primary hypothesis was that there are differences in accuracy of correct assessment/error recognition depending on camera perspective. Generalized linear multi-level analyses assuming a binomial distribution and a logit link were employed to account for the dependency between each evaluator's seven ratings. Results Of 651 video sequences, cardiopulmonary resuscitation performance was evaluable in 96.8% and correctly evaluated in 74.5% over all camera positions. Cardiopulmonary resuscitation performance was classified correctly from a side perspective in 81.3%, from a foot perspective in 68.8% and from a head perspective in 73.6%, revealing a significant difference in error recognition depending on the camera perspective ( p = .01). Correct cardiopulmonary resuscitation was mistakenly evaluated to be false in 46.2% over all perspectives. Conclusions Participants were able to recognize significantly more mistakes when the camera was located on the opposite side of the cardiopulmonary resuscitation provider. Foot position should be avoided in order to enable the dispatcher the best possible view to evaluating cardiopulmonary resuscitation quality.

Optimal well-being in the aftermath of anxiety disorders: A 10-year longitudinal investigation

Background: Although preliminary research has explored the possibility of optimal well-being after depression, it is unclear how rates compare to anxiety. Using Generalized Anxiety Disorder (GAD) and Panic Disorder (PD) as exemplars of anxiety, we tested the rates of optimal well-being one decade after being diagnosed with an anxiety disorder. Based on reward deficits in depression, we pre-registered our primary hypothesis that optimal well-being would be more prevalent after anxiety than depression as well as tested two exploratory hypotheses.Method: We used data from the Midlife in the United States (MIDUS) study, which contains a nationally representative sample across two waves, 10 years apart. To reach optimal well-being, participants needed to have no symptoms of GAD, PD, or major depressive disorder (MDD) at the 10 year follow-up and exceed cut-offs across nine dimensions of well-being.Results: The results failed to support our primary hypothesis. Follow-up optimal well-being rates were highest for adults previously diagnosed with MDD (8.7%), then PD (6.1%), and finally GAD (0%). Exploratory analyses revealed optimal well-being was approximately twice as prevalent in people without anxiety or depression at baseline and provided partial support for baseline well-being predicting optimal well-being after anxiety. Results were largely replicated across different classifications of optimal well-being.Limitations: Findings are limited by the somewhat unique measurement of anxiety in the MIDUS sample as well as the relatively high rate of missing data.Conclusions: We discuss possible explanations for less prevalent optimal well-being after anxiety vs. depression and the long-term positivity deficits from GAD.

The Role of Industrial Ecology in Maximizing the Value of the Organization

The research aims to show the role of industrial ecology in optimizing the value of mineral water industry organizations in the city of Dohuk through the adoption of a significant problem: What is the role of industrial ecology in optimizing the value of organizations? The researcher has adopted a primary hypothesis in studying the problem. The researcher also measured the reality of the problem and the validity of the hypothesis on the method of opinion questionnaire: a sample of organizations of mineral water industry consisting of 27 individuals using a questionnaire consisting of a set of questions related to the independent research variables (industrial ecology) and the approved variable (the value of the organization). The number of questions related to the independent variable was 10 questions, and 16 questions were related to the dependent variable. Then the researchers used some statistical methods in analyzing the questionnaire. The relationship and impact between industrial ecology and the value of the organization has been settled. The researchers have reached a significant conclusion that there is a positive correlation between the two research variables and that the industrial ecology affects the maximization of the value of mineral water industry organizations in the market of the city of Dohuk (0.114 once).

A corpus-based study on opinions of advocates general of the court of justice of the European Union: changes in language and style

This paper presents a Corpus Linguistics study of lexical features in the Opinions of Advocates General (AGs) of the Court of Justice of the European Union (CJEU). Using an interdisciplinary approach, combining legal studies, corpus linguistics and translation studies theories, the study aims to compare the language of some AGs’ Opinions, before and after the introduction of changes in the CJEU’s linguistic regime relating to the language(s) in which Opinions are normally drafted. The results of the corpus linguistic analysis demonstrate that certain changes in the linguistic and stylistic nature of AGs’ Opinions can be observed post-2004. On the one hand, those changes corroborate the study’s primary hypothesis that AG Opinions drafted after 2004 in non-mother tongue languages are stylistically simpler and less ‘fluent’ than those drafted (in AGs’ mother tongues) before 2004. On the other hand, the results also indicate that AG Opinions drafted after 2004 in mother tongue languages are similarly becoming stylistically simpler. These results are inherently interesting in terms of Corpus Linguistics research. However, in order to have a value outside of that field, they are best considered as a basis for more nuanced research questions, which can be investigated through interdisciplinary methods taking account of the factors of production of AG Opinions.
