Specifying Hybrid Models of Teachers’ Work During COVID-19

The term “hybrid” emerged as a common descriptor of pandemic-modified schooling configurations. Yet this umbrella term insufficiently captures the variations among hybrid models, particularly as it pertains to the structure of teacher workdays and related workload demands. Drawing on qualitative research documenting K–12 U.S. teachers’ experience teaching during COVID-19, this brief introduces and explicates three terms specifying structural hybrid models—parallel, alternating, and blended—and their implications for teachers’ work. Differentiating among the models facilitates future analysis of the implications of hybrid schooling for teacher and student experience. Initial analysis indicates teachers experienced one model, blended hybrid, as more challenging than others. This teacher perception highlights the need to discern among the three hybrid models more closely when analyzing schools’ responses to the pandemic. Differentiating among hybrid models may prompt future analysis of hybrid schooling for teacher workload and student learning.

Ship resistance performances assessment for a containership

The present work is focused on ship resistance performances assessment for a given capacity containership. Starting from the main dimensions of a parent ship, other ten hull forms have been generated using DELFTship free program. For each case, the hydrodynamic ship resistance has been calculated using an inhouse code. The objective was to modified some geometrical parameters to obtain shapes of the hull that would provide the least resistance at the required transport capacity. The results obtained will be used in a future analysis related to the impact of hull forms improvements and ship resistance reduction on the propulsive performance and CO2 emissions per transport work.

Fear after being fired: the moderating role of resilience in lessening the time between employment

PurposeThe purpose of this paper is to study how the interplay of the emotion of fear and the personality trait of resilience affect time to reemployment after job termination. The authors carried out the research by extending affective events theory (AET) beyond the workplace.Design/methodology/approachThis paper is a conceptual paper intended to lay the groundwork for future analysis in the areas of fear and resilience, specifically in the time after job termination.FindingsThe paper suggests that fear is a natural response to job termination, and there are two responses to fear: one of action to rid oneself of fear (“fight or flight”) and one of paralysis, in which an individual remains in a fear state. The authors put forth that one's level of resilience is a factor in determining time to reemployment.Originality/valueWhile there are numerous studies on the role emotions play in the workplace and in particular, the role of fear about potentially getting fired, there are few, if any, studies on the role of fear after losing a job. The authors feel this is a warranted area of study as fear can have both positive and negative responses. The authors also contend that a major diver of these fear responses is an individual's level of resilience, and this can be a significant predictor of the individual's time to reemployment.

Railway emergency plan modeling based on Petri net

Purpose When a railway emergency occurs, it often leads to unexpected consequences, especially for trains of higher speed and larger passenger flow. Therefore, the railway emergency plan, a pre-established plan to deal with emergencies, plays an important role in reducing injuries and losses. However, the existing railway emergency plans remain as plain-text documents, requiring lots of manual work to capture the important regulations. This paper aims to propose a visualized, formal and digital railway emergency plan modeling method based on hierarchical timed Petri net (HTPN), which is also of better interpretability. Design/methodology/approach First, the general railway emergency plan was analyzed. Second, the HTPN-based framework model for the general railway emergency plan was proposed. Then, the instantiated model of electric multiple units rescue emergency plan was built by ExSpect, a Petri net simulation tool. Findings The experiments show that the proposed model is more digital and of better readability, visualization and performability, and, meanwhile, can generally conform to the practice well, offering a promising reference for future analysis of the optimization of railway emergency plans. Originality/value This study offers a promising reference for future analysis of the optimization of railway emergency plans.

Refutation of neoliberal educational policies based on Millian principles

This article attempts to start an in-depth consideration and analysis of modern neoliberal education policy through its philosophical roots. To achieve this, the article considers the ideology and philosophy of the classical liberal philosopher John Stuart Mill and the relationship of his philosophy with the modern-day neoliberalist education policy. The purpose of the article is to discuss the philosophical groundwork that drives Mill’s ideas on the establishment of education and compares it to the philosophical groundwork and implications present in modern neoliberal education policy, and through this begin to assert what neoliberalist education policy is. The paper asserts that while Mill’s version of classical liberalism holds similar views and forms of occurrence with modern neoliberalist policies, in many cases Mill’s philosophical groundwork seems to disagree fundamentally with that of neoliberalism. The study is based on literature detailing both the philosophical as well as polity aspects of both Mill’s ideas and modern neoliberalism from the viewpoint of education, and it presents considerations for the nature of neoliberal education policy and its future analysis.

Uma proposta de implementação do Gnômon eletrônico

The Gnomon is the oldest object used by man to measure time, manipulated for observations, ancient astronomers could determine time measurement patterns such as solstices and equinoxes. In this perspective, this article aims to show the implementation and construction of an electronic Gnomon using Arduino microcontroller and Light Dependent Resistors (LDR) in order to make the sun's direction available via the internet and store its data for future analysis and pattern comparisons.

An ordinal model for analysis of years of education

Years of education is a commonly used outcome variable in many lifecourse studies. We argue that such studies may derive additional insights from a treatment of years of education as an ordinal outcome rather than the standard treatment using the linear model. Via simulation, we show that the ordinal approach performs well if the linear model is actually the true model while, in the reverse scenario, estimates from the linear model may be somewhat suboptimal when the ordinal model is the true model. We use data from the Health and Retirement Study to illustrate additional insights that are readily derived from application of the ordinal model and offer a suggested workflow for future analysis.

Artillery Supported by Infantry: The Royal Artillery at the Battle of Monmouth Courthouse

This paper analyzes three questions concerning the Royal Artillery at the Battle of Monmouth Courthouse: how many artillery pieces were used during the battle, which units were employed, and what role the Royal Artillery played in relationship to its parent organizations, the British Army and the British Board of Ordnance. Each of these topics have been seldom discussed, especially in connection to the narrative of the Battle of Monmouth. It is hoped that these inquiries can provide some clarity on the Royal Artillery’s part in the battle, and might spark new efforts of research by future scholars of the American Revolutionary War. In examining these points, careful attention was made in discussing the overall structure of the Royal Artillery and offering a comparison/contrast with its opponent: the Continental Artillery. The main primary source consulted in this discussion was the official Papers of Brigadier-General James Pattison, commander of Royal Artillery forces in North America. These research endeavors resulted in a concrete number of guns used during the Monmouth campaign, some strong indications for the particular units employed, as well as some new insights concerning the traditional interpretation of the battle that may require future analysis.

Functional Properties of Tilapia Collagen, a Systematic Review Propriedades

This systematic review aimed to list the functional properties attributed to collagen obtained from tilapia in scientific studies. The results showed that the antioxidant property is related to the form in which the collagen is presented and the method of antioxidant activity evaluation. It was observed a greater antioxidant activity in the collagen hydrolysate extract obtained from the skin, which plays an important role in the skin chronological aging and in the inhibitory capacity of the photoaging. The functional properties of tilapia collagen hydrolysate should be the object of future analysis in order to complement this research, before integrating them into the list of food or ingredients applicable to the food industry.
