Cohomologies on almost complex manifolds and the ∂∂ˉ\partial \bar{\partial}-lemma

We study cohomologies on an almost complex manifold $(M, J)$, defined using the Nijenhuis-Lie derivations $\mathcal{L}_J$ and $\mathcal{L}_N$ induced from the almost complex structure $J$ and its Nijenhuis tensor $N$, regarded as vector-valued forms on $M$. We show how one of these, the $N$-cohomology $H^{\bullet}_N (M)$, can be used to distinguish non-isomorphic non-integrable almost complex structures on $M$. Another one, the $J$-cohomology $H^{\bullet}_J (M)$, is familiar in the integrable case but we extend its definition and applicability to the case of non-integrable almost complex structures. The $J$-cohomology encodes whether a complex manifold satisfies the $\partial \bar{\partial}$-lemma, and more generally in the non-integrable case the $J$-cohomology encodes whether $(M, J)$ satisfies the $\mathrm{d} \mathcal{L}_J$-lemma, which we introduce and motivate in this paper. We discuss several explicit examples in detail, including a non-integrable example. We also show that $H^k_J$ is finite-dimensional for compact integrable $(M, J)$, and use spectral sequences to establish partial results on the finite-dimensionality of $H^k_J$ in the compact non-integrable case.Comment: 23 pages.

An Exploratory Study on Adolescents Experiences of Using ICQ (I Seek You)

Little research exists into adolescents rationales for using ICQ (I Seek You) and these adolescents relationships with their peers, families, and strangers in ICQ communication. Our curiosity about these subjects led us to adopt a qualitative inquiry, a multiple case study of ten adolescents via purposive sampling. Three major results were discerned: (1) rationales for using ICQ as a major communication tool and for its entertainment functions, (2) contents of ICQ included the participants school lives, peer relationships, family issues, and playing games, and (3) the participants relationships with their peers, family, and strangers like female adolescents are more protective than males. Finally, adolescents voices should be amplified in order to let adults respond to their contextual practices such as ICQ

Vaccines for prophylaxis of viral infections in patients with hematological malignancies.

Viral infections cause significant morbidity and mortality in patients with hematological malignancies. It remains uncertain whether viral vaccinations in these patients are supported by good evidence. We aimed to determine the effectiveness and safety of viral vaccines in patients with hematological malignancies. We searched Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, CINAHL (June 2010), reference lists of relevant papers, abstracts from scientific meetings and contacted vaccine manufacturers. Randomized controlled trials (RCTs) evaluating viral vaccines in patients with hematological malignancies were included. Relative risk (RR) was used for binary data and mean difference (MD) for continuous data. Primary outcome was incidence of infection. Secondary outcomes were mortality, incidence of complications and severe viral infection, hospitalization, immune response and adverse effects. Fixed-effect model was used in meta-analyses. Eight RCTs were included, with 305 patients in the intervention groups and 288 in the control groups. They evaluated heat-inactivated varicella zoster virus (VZV) vaccine (two trials), influenza vaccines (five trials) and inactivated poliovirus vaccine (IPV) (one trial). Seven trials had high and one trial had moderate risk of bias.VZV vaccine might reduce herpes zoster compared to no vaccine (RR 0.54, 95% CI 0.3 to 1.0, P=0.05), but not statistically significant. Vaccination also demonstrated efficacy in immune response but frequently caused local adverse effects. One trial reported severity score of zoster, which favored vaccination (MD 2.6, 95% CI 0.94 to 4.26, P=0.002).Two RCTs compared inactivated influenza vaccine with no vaccine and reported lower risk of lower respiratory infections (RR 0.39, 95% CI 0.19 to 0.78, P=0.008) and hospitalization (RR 0.17, 95% CI 0.09 to 0.31, P<0.00001) in vaccine recipients. However, vaccine recipients more frequently experienced irritability and local adverse effects. There was no significant difference in seroconversion between one and two doses of influenza vaccine (one trial), or between recombinant and standard influenza vaccine (one trial), or influenza vaccine given with or without re-induction chemotherapy (one trial).The IPV trial comparing vaccination starting at 6 versus 18 months after stem cell transplant (SCT) found no significant difference in seroconversion. Inactivated VZV vaccine might reduce zoster severity in adult SCT recipients. Inactivated influenza vaccine might reduce respiratory infections and hospitalization in adults with multiple myeloma or children with leukemia or lymphoma. However, the quality of evidence is low. Local adverse effects occur frequently. Further high-quality RCTs are needed.link_to_subscribed_fulltex

Nurses’ attitudes toward family witnessed resuscitation in Western Australian emergency departments

Since 1982, healthcare institutions and professionals have been questioning whether family members should be allowed to enter resuscitation rooms during such critical period of treatment. A self-administered questionnaire is used in this research to investigate Western Australian emergency nurses’ attitudes towards family witnessed resuscitation and to explore possible factors influencing their attitudes.The findings of this work suggest that nurses, assuming a betwixt-between position, evaluate the costs and benefits of allowing family presence in the resuscitation room from patients, families and healthcare professionals’ perspectives. Nurses have an overwhelming agreement on the beneficial aspects of the practice, while also share concerns commonly reported in previous studies with an emphasis on a family member’s capability to cope with and comprehend the resuscitation procedures and a healthcare professional’s ability to handling pressure.Overall, the research suggests nurses are ambivalent in their attitude. Despite the nurses’ awareness of some family members’ desire to witness resuscitation and their reported benefits, in doing so, they are reluctant to initiate or formally incorporate this practice as a standard procedure. There is also a lack of consensus on the management of families’ presence, however, nurses agree on the need for preresuscitation assessment, support staff during resuscitation and post-resuscitation debriefing. Institutional factor is identified as a significant influence on nurses’ attitudes. This work will provide useful input in the future development of guidelines and will help stimulate discussion on this topic in Western Australia

The Spectrum of Virtue: From the Decent to the Excellent

What makes an action morally good, worthy, or virtuous? I offer a pluralist answer to this by considering a spectrum of actions, especially those with many motives. There are, I argue, two types of good motives: concerns simply for what is (pro tanto) right or good as such and concerns simply for matters, such as pleasing or protecting someone for its own sake, that make actions (pro tanto) right or good, independently of their being right-or-good-makers. Acting from either type is good, and acting from both types in the right proportion is best. But between the most excellent and the minimally decent actions, vast, unexamined varieties exist. We may act from mixed motives, or from ones that are good and ones that are bad or neutral. We may fail to act from better motives. We may fail to care about the costs of what we do. And even when we act rightly, we may be lured by bad or neutral temptations to act wrongly. Despite not acting from the best motives, such actions may still be to differing degrees good. By exploring such actions, I develop an account to assess when and how good any action is.The pluralist view I develop draws on the ideas of early twentieth-century British ethicists, especially W. D. Ross. Although the view is intuitive, it is neglected in the current literature, which is dominated by monist views. I revive the pluralist view as a superior, competing view. I reconsider classic cases, in which we are simply acting solely from good motives, and introduce new ones, in which our psychology is messier and more realistic. I draw our attention to important but overlooked moments in our lives where we are acting from mixed motives, where we are acting solely from a good motive but are indifferent to very important concerns, and where we are tempted to do what is wrong by good, bad, or neutral concerns.Ph.D

Hong Kong dentists' preparedness for medical emergency in dental clinics

Aim: The aim of this study was to investigate the Hong Kong dentists’ and dental clinics’ preparedness for medical emergency in the dental clinic. Methods: Two custom designed questionnaires were developed, one for dentists and another for dental clinics, to collect the required information. The sampling frame for participants was the list of registered dentists published by the Hong Kong Dental Council on its website in January 2016. A total of 434 dentists and 143 dental clinics were selected from the list by systematic random sampling. The latter sample was supplemented by 10 randomly selected government dental clinics. The questionnaires were mailed the selected dentists together with a cover letter and a stamped return envelope. A reminder letter and another copy of the questionnaire were sent out two weeks after the first mailing. Results: 167 (38%) completed dentist questionnaires and 53 (35%) clinic questionnaires were collected. Most of the respondent dentists had some deficient knowledge on basic life support (BLS), their mean score was 3.5 out of a maximum of 5. Most (>60%) of the respondents thought they were competent in performing medical emergency procedures except giving intravenous injection. Moreover, most (>60%) of them held positive attitude towards having immediate availability of essential medical emergency equipment and drugs in their clinic. Dentists who were more recent graduates, those with postgraduate qualifications, and those who work with accompaniment generally had higher mean BLS knowledge scores. In the dental clinics, the most commonly kept medical emergency equipment/drug was instant glucose (70%) and followed by antihistamine (62%). Only a quarter of the clinics were equipped with AED, and 45% were equipped with oxygen cylinder. For 8 out of the 11 items, a higher proportion of the bigger clinics (>2 dental chairs) than the smaller clinics had the medical emergency equipment/drug available (Chi-square test, p<0.05). Conclusion: Hong Kong dentists have a moderate level of knowledge on BLS which should be enhanced through regular attendance at CE courses. Their knowledge level is affected by a number of their background and professional activities factors. Most dental clinics in Hong Kong have only few of the essential medical emergency equipment and drugs while the larger clinics are better equipped than the smaller clinics.published_or_final_versio
