Using a modified dot probe task, undergraduate women were trained to direct their attention toward (attend) or away from (avoid) chocolate pictures. Experiment 1 (N = 178) consisted of one training session; Experiment 2 (N = 161) included 5 weekly sessions. Following training, participants viewed television advertisements of chocolate or control products. They then took part in a so-called taste test as a measure of chocolate consumption. Attentional bias for chocolate was measured before training and after viewing the advertisements, and in Experiment 2 also at 24-h and 1-week follow-up. In Experiment 2, but not Experiment 1, participants in the avoid condition showed a significant reduction in attentional bias for chocolate, regardless of whether they had been exposed to advertisements for chocolate or control products. However, this inoculation effect on attentional bias did not generalise to chocolate intake. Future research involving more extensive attentional re-training may be needed to ascertain whether the inoculation effect on attentional bias can extend to consumption, and thus help people withstand exposure to real-world palatable food cues

Comorbid insomnia and obstructive sleep apnea (OSA) represents a highly prevalent and debilitating condition; however, physicians and researchers are still uncertain about the most effective treatment approach. Several research groups have suggested that these patients should initially receive treatment for their insomnia before the sleep apnea is targeted. The current study aims to determine whether Cognitive and Behavioral Therapy for Insomnia (CBT-i) can effectively treat insomnia in patients with comorbid OSA and whether its effectiveness is impaired by the presence of OSA.
Methods
A retrospective chart review was conducted to examine 455 insomnia patients entering a CBT-i treatment program in a hospital out-patient setting. Three hundred and fourteen patients were diagnosed with insomnia alone and 141 with insomnia and comorbid OSA. Improvements in average sleep diary parameters, global insomnia severity, and several daytime functioning questionnaires from baseline, to post-treatment, to 3-month follow-up were compared between insomnia patients with and without comorbid OSA.
Results
Insomnia patients with comorbid OSA experienced significant improvements in insomnia symptoms, global insomnia severity, and other daytime functioning measures during and following treatment. Furthermore, improvements were no different between patients with or without comorbid OSA. Sleep apnea presence and severity were not related to rates of insomnia-remission or treatment-resistance following treatment.
Conclusions
CBT-i is an effective treatment in the presence of comorbid OSA. This information offers support for the suggestion that patients with comorbid insomnia and OSA should be treated with CBT-i prior to the treatment of the OSA

Supplementary data to this article is available from the publisher's website: http://dx.doi.org/10.1016/j.apsusc.2017.09.243Hydrogen capture and storage is the core of hydrogen energy application. With its high specific surface area, direct bandgap, and variety of potential applications, phosphorene has attracted much research interest. In this study, density functional theory (DFT) is utilized to study the interactions between doped phosphorenes and hydrogen molecules. The effects of different dopants and metallic or nonmetallic atoms on phosphorene/hydrogen interactions is systematically studied by adsorption energy, electron density difference, partial density of states analysis, and Hirshfeld population. Our results indicate that the metallic dopants Pt, Co, and Ni can help to improve the hydrogen capture ability of phosphorene, whereas the nonmetallic dopants have no effect on it. Among the various metallic dopants, Pt performs very differently, such that it can help to dissociate H2 on phosphorene. Specified doped phosphorene could be a promising candidate for hydrogen storage, with behaviors superior to those of intrinsic graphene sheet
The National Eye Survey of Trinidad and Tobago (NESTT): Rationale, Objectives and Methodology

The main objective of this survey is to obtain prevalence estimates of vision impairment and blindness for planning and policy development.
Methods: A population-based, cross-sectional survey was undertaken using random multistage cluster sampling, with probability-proportionate-to-size methods. Eligible participants aged 5 years and older were sampled from the non-institutional population in each of 120 cluster segments. Presenting distance and near visual acuity were screened in their communities. People aged 40 years and older, and selected younger people, were invited for comprehensive clinic assessment. The interview included information on potential risk factors for vision loss, associated costs and quality of life. The examination included measurement of anthropometrics, blood glucose, refraction, ocular biometry, corneal hysteresis, and detailed assessment of the anterior and posterior segments, with photography and optical coherence tomography imaging. Adult participants were invited to donate saliva samples for DNA extraction and storage.
Results: The fieldwork was conducted over 13 months in 2013–2014. A representative sample of 10,651 individuals in 3410 households within 120 cluster segments identified 9913 people who were eligible for recruitment.
Conclusion: The study methodology was robust and adequate to provide the first population-based estimates of the prevalence and causes of visual impairment and blindness in Trinidad and Tobago. Information was also gathered on risk factors, costs and quality of life associated with vision loss, and on normal ocular parameters for the population aged 40 years and older

Intersecting Memory and Witnessing Violence in Anita Desai’s The Zigzag Way
This essay engages with the juxtaposition of two disparate violent past events: the Holocaust, and the Mexican Revolution, which led to the forced displacement of the diasporic characters in Anita Desai’s novel The Zigzag Way. It explores various ways in which the violent past resurfaces in the present and enables different migrant characters of the novel to bear witness to it by using tropes such as ruin, dreams and spectres. The essay also demonstrates subtle and complex intersections among different memory theories to articulate victimisation and enforced silence of the displaced and traumatized characters. It also investigates the role of fiction in depicting the ‘unspeakable’ horrors of the tumultuous past and the readers’ as well as the characters’ implication in it as secondary witnesses
Dumping Grounds: Donald Trump, Edward Abbey and the Immigrant as Pollution
Announcing his bid for the US presidency, Donald Trump caused outrage by claiming that undocumented migration from Mexico to the US showed that America had ‘become a dumping ground for everyone else’s problems’. Trump began his typically bombastic speech by declaring that the Mexican government was ‘sending people that have lots of problems ... they’re bringing drugs, they’re bringing crime. They’re rapists.’ However, Trump’s framing of undocumented migrants turning America in a ‘dumping ground’, whilst shocking, can be clearly situated within a persistent strain of rhetoric in mainstream American culture and media that uses imagery of pollution and toxic waste to depict Mexican immigration. In this essay, I want to show how such rhetoric and imagery survives in popular American culture and literature as part of a sublimated discourse that adopts and adapts the terminology, imagery and conventions of genres such as travel or nature writing in order to convey a message which implicitly frames the immigrant (and particularly the Hispanic immigrant into America) as a form of pollution. As a case study of this process, I will analyse some previously under-researched articles by American nature and travel writer, Edward Abbey
