In the context of the United Nations’ Sustainable Development Goal for education, this study examines the potential of information, communication, and technology (ICT) as a way to provide quality education for all, with a focus on immigrant youth in the United States. The study uses structural equation models (SEM) to analyze data from a nationally representative data set, Trends in International Mathematics and Science Study (TIMSS)-USA. Focusing on mathematics achievement among immigrant youth (with non-immigrant youth as a reference group), this study explores the effects of ICT access and two types of ICT use for educational purposes: generic and specific. The results indicate that ICT access and specific ICT use both have positive direct, indirect, and total effects on math performance for immigrant youths, while generic ICT use has only a nonsignificant negative effect. In nonimmigrant youths, these ICT variables showed a different pattern, with the effects of ICT access and specific ICT use being less pronounced, but generic ICT use exhibiting a significant negative effect. These findings show the potential role of ICT-mediated education in narrowing the achievement gap between immigrant and nonimmigrant students, thereby helping immigrants better integrate into their destination countries.

Context: Little is known about how the combination of pain severity and duration affects quadriceps function and self-reported function in patients with anterior knee pain (AKP). Objective: To examine how severity (low [≤3 of 10] versus high [>3 of 10]) and duration (short [2 years]) of AKP affect quadriceps function and self-reported function. Design: Cross-sectional study. Setting: Laboratory. Patients or Other Participants: Sixty patients with AKP (mean pain severity = 4 of 10 on the numeric pain rating scale, mean pain duration = 38 months) and 48 healthy control individuals. Patients with AKP were categorized into 3 subdivisions based on pain: (1) severity (low versus high); (2) duration (short versus long); and (3) severity and duration (low and short versus low and long versus high and short versus high and long). Main Outcome Measure(s): Quadriceps maximal (maximal voluntary isometric contraction) and explosive (rate of torque development) strength, activation (central activation ratio), and endurance (average peak torque) and self-reported function (Lower Extremity Functional Scale score). Results: Compared with the healthy control group, (1) all AKP subgroups showed less quadriceps maximal strength (P < .005, d ≥ 0.78) and activation (P < .02, d ≥ 0.85), except for the AKP subgroup with low severity and short duration of pain (P > .32); (2) AKP subgroups with either high severity or long duration of pain showed less quadriceps explosive strength (P < .007, d ≥ 0.74) and endurance (P < .003, d ≥ 0.79), but when severity and duration were combined, only the AKP subgroup with high severity and long duration of pain showed less quadriceps explosive strength (P = .006, d = 1.09) and endurance (P = .0004, d = 1.21); and (3) all AKP subgroups showed less self-reported function (P < .0001, d ≥ 3.44). Conclusions: Clinicians should be aware of the combined effect of severity and duration of pain and incorporate both factors into clinical practice when rehabilitating patients with AKP.

Background: Little is known about how chronic unilateral anterior knee pain (AKP) affects bilateral quadriceps function and lower quarter flexibility. Objective: To determine if patients with chronic unilateral AKP present bilateral deficits in quadriceps function and lower quarter flexibility. Methods: Twenty-two patients with chronic unilateral AKP (pain duration: 48.6 months) and 22 matched healthy controls were evaluated. Pain perception and functional outcomes were obtained. Knee joint and thigh circumferences, quadriceps subcutaneous tissue thickness and function (i.e. maximal and explosive strength, activation, and endurance), and lower quarter flexibility (i.e. hamstrings and iliopsoas/rectus femoris muscle) in both legs were compared across conditions. Results: Knee joint and thigh circumferences, and quadriceps subcutaneous tissue thickness were not different between conditions (P ≥ .39). Compared with matched healthy controls, patients with chronic unilateral AKP showed: 1) greater pain perception (0.0 versus 4.4 cm, P < .0001); 2) a lower score for functional outcomes (79.6 versus 53.9, P < .0001); 3) less bilateral quadriceps maximal (3.5 versus 2.8 Nm/kg, P < .0001) and explosive (10.8 versus 8.7 Nm/kg/s, P = .01) strength, activation (0.95 versus 0.83, P < .0001), and endurance (1.66 versus 1.52 Nm/kg, P = .02); and 4) less bilateral hamstrings (86.8 versus 72.6°, P = .002) and iliopsoas/rectus femoris (11.6 versus 7.8°, P < .05) flexibility. Conclusion: Patients with chronic unilateral AKP (without knee joint effusion or quadriceps muscle atrophy) appear to have bilateral deficits in quadriceps function and lower quarter flexibility, which should be addressed with pain reduction.

Teachers play a critical role in child sexual abuse (CSA) prevention and intervention efforts. We examined the impact of the Second Step Child Protection Unit (CPU) on improving teacher awareness, attitudes, and teacher–student relations for 161 teachers. Teacher baseline scores and treatment acceptability were examined as moderators. Structural equation modeling (SEM) revealed a significant effect of the CPU on teachers’ awareness, attitudes, and teacher–student relations, particularly for teachers with lower prior knowledge, attitudes, and student relationships. Teachers’ acceptability of the CPU also moderated outcomes, where a higher level of acceptability of CSA interventions was associated with an increase in outcomes.
