Effect of Training Modality on Intention to Exercise Among Law Enforcement Cadets Post Academy

Police academies are typically the first formalized job-task-oriented exercise training for law enforcement officers (LEOs). Research has demonstrated that cadets are at higher risk of injury during the academy. Physical training (PT) is a critical component of LEO academy efforts to build occupational skills to meet job demands. Although research is beginning to investigate the efficacy of different training modalities, more research is needed to understand the impact of academy training load and modality on occupational readiness and interest in maintaining exercise behaviors post-academy. PURPOSE: to investigate the relationships between different physical training modalities and intention to continue physical training among cadets after a 12-week police academy. METHODS: A cross-sectional design was utilized with a convenience sample of 236 graduating LEO cadets (27.84 y; 203 male, 30 female). Participants completed a 5-Point Likert Scale for perceived intensity for each exercise modality (formation runs, circuit training, and defensive tactics). Cadets then rated their intention to continue each modality after academy completion (ranging from 1=Extremely Unlikely to 5=Extremely Likely). Spearman-Rho correlations were used to determine the relationship between each training modality and cadets\u27 intention to continue PT after the academy. RESULTS: With Circuit Training, a significant negative weak correlation was found between intensity and intention (rs (229)= -.140, p=.034). No significant correlations were found between intention formation runs or defensive training. CONCLUSION: Though significant, the weak negative correlation does not give a strong inference, and more research into perceived intensity and behavioral intention is warranted to gain a better understanding of this interaction

Effects of Aging on Patellofemoral Joint Stress During Stair Negotiation on Challenging Surfaces

Introduction: Patellofemoral pain is an incessant lower limb musculoskeletal disorder that may be underreported in older adults. During common locomotor activities, such as when negotiating stairs, older adults (over the age of 65 years) adopt knee biomechanics reported to increase patellofemoral pain. Negotiating stairs with a challenging surface, such as uneven or slick, may place greater demand on the knee and further exacerbate joint biomechanics related to PFJ stress. Yet, it is unknown if older adults exhibit increases in patellofemoral joint (PFJ) stress when negotiating stairs with challenging surfaces. Purpose: The purpose of this study was to examine the effect of age (young and older adults) and surface (normal, slick, and uneven) on the magnitude and temporal waveform of patellofemoral joint stress during stair ascent and descent tasks. Methods: Two cohorts (12 young: ages 18-25 years; 12 older: over 65 years) had knee biomechanics quantified after they ascended and descended 18.5 cm stairs on normal, slick, and uneven surfaces at a self-selected speed. Statistical Analysis: Peak of stance (0-100%) PFJ stress and associated components (including PFJ reaction force and contact area, and knee flexion angle and moment) were submitted to a two-way RM ANOVA to test the main effects of and interaction between age (young vs old) and surface (normal, slick, and uneven). A statistical parametric mapping two-way ANOVA was used to determine main effects of and interaction between age and surface for the PFJ stress waveform. Results: During the stair ascent, older adults exhibited greater PFJ stress from 56 to 84% of stance (p \u3c 0.001), which may be attributed to the greater PFJ stress-time integral (p = 0.004) and later peak PFJ stress (p = 0.024) compared to young adults. Additionally, a significant age by surface interaction was observed for time of peak PFJ stress (p = 0.041) during stair ascent, where older adults exhibited a later peak PFJ stress compared to young adults (p = 0.008), and later peak PFJ stress compared to normal and slick surface (both: p = 0.014). Surface impacted PFJ stress waveform (all: p \u3c 0.001), but not magnitude (p \u3e 0.05) during both stair ascent and descent. During stair ascent on the uneven surface, participants exhibited smaller PFJ stress from 8 to 25% of stance compared to normal surface, but greater PFJ stress from 57 to 90% and 49 to 77% of stance compared to the normal and slick surfaces (all: p \u3c 0.001). On the uneven surface, participants exhibited a greater PFJ stress-time integral (both: p = 0.010) compared to the normal and slick surfaces. During stair descent, on the uneven surface, participants only exhibited greater PFJ stress-time integral (p = 0.017) compared to slick surface, while PFJ stress was smaller from 5 to 18% of stance, but greater stress from 92 to 99% of stance (both: p \u3c 0.001) on the slick compared to the normal surface. Conclusion: Older adults are more likely to exhibit knee biomechanics related to PFJ pain development when navigating stairs. Specifically, the larger, later PFJ stress exhibited by older adults when ascending, but not descending the stairs may increase loading of the joint’s articular cartilage and increase risk of developing PFJ pain. Yet, all participants exhibited alterations in knee biomechanics that may lead to greater PFJ stress when negotiating stairs with slick and uneven surfaces

String Fragmentation with a Time-Dependent Tension

Motivated by recent theoretical arguments that expanding strings can be regarded as having a temperature that is inversely proportional to the proper time, tau, we investigate the consequences of adding a term proportional to 1/tau to the string tension in the Lund string-hadronization model. The lattice value for the tension, kappa0 ~ 0.18 GeV^2 ~ 0.9 GeV/fm, is then interpreted as the late-time/equilibrium limit. A generic prediction of this type of model is that early string breaks should be associated with higher strangeness (and baryon) fractions and higher fragmentation values. It should be possible to use archival ee data sets to provide model-independent constraints on this type of scenario, and we propose a few simple key measurements to do so.Comment: v2: included predictions for strange baryon

What "triggers" mortgage default?

This paper assesses the relative importance of two key drivers of mortgage default: negative equity and illiquidity. To do so, the authors combine loan-level mortgage data with detailed credit bureau information about the borrower's broader balance sheet. This gives them a direct way to measure illiquid borrowers: those with high credit card utilization rates. The authors find that both negative equity and illiquidity are significantly associated with mortgage default, with comparably sized marginal effects. Moreover, these two factors interact with each other: The effect of illiquidity on default generally increases with high combined loan-to-value ratios (CLTV), though it is significant even for low CLTV. County-level unemployment shocks are also associated with higher default risk (though less so than high utilization) and strongly interact with CLTV. In addition, having a second mortgage implies significantly higher default risk, particularly for borrowers who have a first-mortgage LTV approaching 100 percent.Mortgages ; Default (Finance)

A view from the countryside : pollen from a field at Mistra Valley, Malta

Although historical sources for the Early Modern development of the Maltese landscape are abundant and well-documented, these records are uncorroborated by other forms of evidence. As part of investigations of the development of a field system at Mistra Valley, Malta, a sample was taken from a waterlain layer at the base of a field-fill on the edge of the valley-floor in Mistra Valley. Pollen and other analyses were done on this layer to identify the environment and agriculture of an early stage in the field system.peer-reviewe

Redox regulation of the mitogen-activated protein kinase pathway during lymphocyte activation

AbstractWe have previously demonstrated an obligatory requirement for intracellular reactive oxygen species generation during T lymphocyte activation, and have proposed that intracellular reactive oxygen species may act as signalling agents in the regulation of certain cellular processes, for example, during cell cycle entry. To test this hypothesis, we have been interested to determine which, if any, cell cycle entry events are affected by oxidative signalling. In earlier studies, we have identified the transcription factors NF-κB and AP-1 as molecular targets for oxidative signalling processes during cell cycle entry, and have shown that oxidative signalling is involved in the regulation of early changes in gene expression during the G0 to G1 phase transition. To extend these initial observations, we have examined the effect of antioxidant treatment on the activity of the mitogen-activated protein kinases erk1 and erk2, as members of a signal transduction pathway known to directly regulate transcription factor function. Using as a probe cysteamine, an aminothiol compound with both antioxidant and antiproliferative activity, we have identified erk2, a key element of the MAP kinase pathway, as being responsive to oxidative signalling during lymphocyte activation. These observations provide further evidence to suggest a role for intracellular oxidant generation as a regulatory mechanism during cell cycle entry, and establish a link between oxidative signalling and other aspects of the intracellular signalling network that is activated in response to mitogenic stimulation

The Radical Potential of Public Hearings: A Rhetorical Assessment of Resistance and Indecorous Voice in Public Participation Processes

Little scholarship in environmental communication has considered the intersections between public participation and social movement. We fill this gap by discussing how public participation process can become sites of radical politics when publics employ disruptive or improper tactics, known as indecorous voice. Indecorum can be used to sustain protest matters beyond official forums, engage multiple audiences, and forge new identities among publics. We demonstrate the utility of indecorum through two case studies: Love Canal, NY where residents combat exposure to toxic chemicals, and Salt Lake City, UT, where publics challenge industrial expansion in a fight for clean air
