The Impact of Federalism on Immigration: A Reconstruction of the System to Alleviate the Immigration Crisis in America

Illegal immigration is a complex and relevant issue in the United States. In particular, its long-term implications for American communities has elevated its significance. Within America’s federalist system, the immigration dilemma has raised tension among federal, state, and local governments, which have different perspectives on how to approach the matter. The federal government is responsible for enforcing immigration laws but delegates numerous immigration responsibilities to state and local law enforcement. However, the degree to which local officials should cooperate with federal authorities is the subject of intense debate. Should immigration enforcement be a federal or local responsibility? Under federalism and other political principles, this responsibility should be uniquely shared and balanced in order to alleviate the immigration crisis

Creating interaction in online learning: a case study

This paper uses the case‐study method to examine detailed data related to student and tutor usage of an asynchronous discussion board as an interactive communication forum during a first‐semester associate degree course in applied psychology at the City University of Hong Kong. The paper identifies ‘what works’ in relation to discussion board use, demonstrating how students might gradually create an online community of their own, but only if prompted in a timely and appropriate way by the course structure. It also identifies three distinct phases in online interaction and suggests these might, to some extent, be mediated by assessment tasks

174— Developing Oxidation of Alcohols in Sand

We present the oxidation of alcohols into aldehydes and ketones using (NH4)2Cr2O7 in sand. Several alcohols undergo oxidation using an appropriate solvent to afford aldehyde and ketones in good yields. The reactions were analyzed by TLC, 1H and 13C-NMR. The developed reaction is also compared to reactions done using silica gel

Why don't poor men eat fruit? Socioeconomic differences in motivations for fruit consumption.

BACKGROUND: Those of lower socioeconomic status (SES) tend to have less healthy diets than those of higher SES. This study aimed to assess whether differences in motivations for particular foods might contribute to socioeconomic differences in consumption. METHODS: Participants (n = 732) rated their frequency of consumption and explicit liking of fruit, cake and cheese. They reported eating motivations (e.g., health, hunger, price) and related attributes of the investigated foods (healthiness, expected satiety, value for money). Participants were randomly assigned to an implicit liking task (Single Category Implicit Association Task) for one food category. Analyses were conducted separately for different SES measures (income, education, occupational group). RESULTS: Lower SES and male participants reported eating less fruit, but no SES differences were found for cheese or cake. Analyses therefore focused on fruit. In implicit liking analyses, results (for income and education) reflected patterning in consumption, with lower SES and male participants liking fruit less. In explicit liking analyses, no differences were found by SES. Higher SES participants (all indicators) were more likely to report health and weight control and less likely report price as motivators of food choices. For perceptions of fruit, no SES-based differences were found in healthiness whilst significant interactions (but not main effects) were found (for income and education) for expected satiety and value for money. Neither liking nor perceptions of fruit were found to mediate the relationship between SES and frequency of fruit consumption. CONCLUSIONS: There is evidence for social patterning in food motivation, but differences are modified by the choice of implicit or explicit measures. Further work should clarify the extent to which these motivations may be contributing to the social and gender patterning in diet.The study was funded by the Department of Health Policy Research Programme (Policy Research Unit in Behaviour and Health [PR-UN-0409-10109]).This is the final version.

Priming healthy eating. You can't prime all the people all of the time.

OBJECTIVE: In the context of a food purchasing environment filled with advertising and promotions, and an increased desire from policy makers to guide individuals toward choosing healthier foods, this study tests whether priming methods that use healthy food adverts to increase preference for healthier food generalize to a representative population. METHODS: In two studies (Study 1 n = 143; Study 2 n = 764), participants were randomly allocated to a prime condition, where they viewed fruit and vegetable advertisements, or a control condition, with no advertisements. A subsequent forced choice task assessed preference between fruits and other sweet snacks. Additional measures included current hunger and thirst, dietary restraint, age, gender, education and self-reported weight and height. RESULTS: In Study 1, hunger reduced preferences for fruits (OR (95% CI) = 0.38 (0.26-0.56), p <0.0001), an effect countered by the prime (OR (95% CI) = 2.29 (1.33-3.96), p = 0.003). In Study 2, the effect of the prime did not generalize to a representative population. More educated participants, as used in Study 1, chose more fruit when hungry and primed (OR (95% CI) = 1.42 (1.13-1.79), p = 0.003), while less educated participants' fruit choice was unaffected by hunger or the prime. CONCLUSION: This study provides preliminary evidence that the effects of adverts on healthy eating choices depend on key individual traits (education level) and states (hunger), do not generalize to a broader population and have the potential to increase health inequalities arising from food choice.We gratefully acknowledge the participation of all NIHR Cambridge BioResource (CBR) volunteers.

Recreational specialization and the marine-based conservation behaviour intention of recreational divers in Hong Kong

This study examined divers' recreational specialization, pro-environmental attitudes, and marine-based conservation behaviour intentions. A questionnaire-based data collection approach was used to survey 398 divers who visited popular diving sites in Hong Kong by employing structural equation modelling to determine the potential relationships among the proposed variables. The results showed a statistically positive relationship between divers' recreational specialization and their pro-environmental attitudes, along with a statistically valid relationship between divers' recreational specialization and their marine-based conservation behaviour intentions. However, divers' pro-environmental attitudes were not statistically significant with their marine-based conservation behaviour intentions; thus, the discrepancy regarding different research findings between the current and previous studies was further discussed. In particular, our findings confirmed that recreational specialization could be a reliable predictor of divers' pro-environmental attitudes and marine-based conservation behaviour intentions to fill the research gaps regarding scuba diving-based nature tourism in Hong Kong. Consequently, management implications and recommendations were presented in accordance with the development of marine environmental conservation and sustainable scuba diving tourism in Hong Kong

Exploring the Role of Determinants Affecting Responsible Underwater Behaviour of Marine-Based Tourists

This study utilised divers’ demographic characteristics, diving experience, and attitudes to analyse the association between these factors and divers’ responsible underwater behaviour among Chinese scuba divers in Hong Kong. More innovatively, the measurement construct of diving attitude was further employed as a mediator to investigate its influence on the relationship between divers’ diving experience and responsible underwater behaviours based on the conceptual framework of previous works in the literature. The questionnaire data for this study were collected at four of the most popular dive sites among the marine protected areas in Hong Kong, with 398 valid samples after eliminating incomplete questionnaires. Regression results demonstrated that divers’ demographic characteristics could significantly predict their responsible underwater behaviour, with age (b = 0.10, p &lt; 0.05) and education (b = 0.15, p &lt; 0.05) being found to be positively associated with their diving behaviour. In addition, path analysis demonstrated that divers’ diving experience and attitude could explain 13.6% and 22.6% of the variance in predicting their responsible diving behaviour, respectively. However, no mediation effect was found on the relationship between diving experience and responsible underwater behaviour relative to diving attitude, given the absence of statistical effects regarding the positive impact of divers’ diving experience on their attitude (β = 0.024, se = 0.022, t = 1.085, p = 0.279). Based on the research findings, theoretical and practical implications were discussed correspondingly, which are believed to be beneficial in promoting marine conservation and the sustainable development of marine-based nature tourism in Hong Kong

Screening, diagnosis and treatment of iron deficiency in chronic heart failure:putting the 2016 European Society of Cardiology heart failure guidelines into clinical practice

Iron deficiency is common in patients with chronic heart failure (CHF) and is associated with reduced exercise performance, impaired health-related quality of life and an increased risk of mortality, irrespective of whether or not anaemia is present. Iron deficiency is a serious but treatable condition. Several randomized controlled clinical trials have demonstrated the ability of intravenous (IV) iron, primarily IV ferric carboxymaltose (FCM), to correct iron deficiency in patients with heart failure with reduced ejection fraction (HFrEF), resulting in improvements in exercise performance, CHF symptoms and health-related quality of life. The importance of addressing the issue of iron deficiency in patients with CHF is reflected in the 2016 European Society of Cardiology (ESC) heart failure guidelines, which recognize iron deficiency as an important co-morbidity, independent of anaemia. These guidelines recommend that all newly diagnosed heart failure patients are routinely tested for iron deficiency and that IV FCM should be considered as a treatment option in symptomatic patients with HFrEF and iron deficiency (serum ferritin</p
