Modeling your college library after a commercial bookstore? the Hong Kong Design Institute Library experience

The Hong Kong Design Institute (HKDI) is a leading design education institute in Hong Kong under the Vocational Training Council (VTC) group. Opened in September 2010, the HKDI Learning Resources Centre is a specialist library for the study of art and design. The mission of the HKDI Library is to support and promote the academic goals of the Institute, i.e., to prepare the students for professional careers; emphasize learning through a creative and interactive environment; meanwhile uphold a positively relaxing, and yet inviting environment that is very much similar to a commercial bookstore. In order to accomplish this, the HKDI Library aims to serve as a user-centered library for creative learning--by providing an important place for both students and faculty to actively engage in study, research, as well as socializing. Through a series of small focus group interviews with both students and faculty staff at the HKDI, the study investigates how influential the library environment could be in fostering students\u27 learning and other social activities under a creative environment

School-based prevention for adolescent Internet addiction: prevention is the key. A systematic literature review

Adolescents’ media use represents a normative need for information, communication, recreation and functionality, yet problematic Internet use has increased. Given the arguably alarming prevalence rates worldwide and the increasingly problematic use of gaming and social media, the need for an integration of prevention efforts appears to be timely. The aim of this systematic literature review is (i) to identify school-based prevention programmes or protocols for Internet Addiction targeting adolescents within the school context and to examine the programmes’ effectiveness, and (ii) to highlight strengths, limitations, and best practices to inform the design of new initiatives, by capitalizing on these studies’ recommendations. The findings of the reviewed studies to date presented mixed outcomes and are in need of further empirical evidence. The current review identified the following needs to be addressed in future designs to: (i) define the clinical status of Internet Addiction more precisely, (ii) use more current psychometrically robust assessment tools for the measurement of effectiveness (based on the most recent empirical developments), (iii) reconsider the main outcome of Internet time reduction as it appears to be problematic, (iv) build methodologically sound evidence-based prevention programmes, (v) focus on skill enhancement and the use of protective and harm-reducing factors, and (vi) include IA as one of the risk behaviours in multi-risk behaviour interventions. These appear to be crucial factors in addressing future research designs and the formulation of new prevention initiatives. Validated findings could then inform promising strategies for IA and gaming prevention in public policy and education

Reducing the environmental impact of surgery on a global scale: systematic review and co-prioritization with healthcare workers in 132 countries

Background Healthcare cannot achieve net-zero carbon without addressing operating theatres. The aim of this study was to prioritize feasible interventions to reduce the environmental impact of operating theatres. Methods This study adopted a four-phase Delphi consensus co-prioritization methodology. In phase 1, a systematic review of published interventions and global consultation of perioperative healthcare professionals were used to longlist interventions. In phase 2, iterative thematic analysis consolidated comparable interventions into a shortlist. In phase 3, the shortlist was co-prioritized based on patient and clinician views on acceptability, feasibility, and safety. In phase 4, ranked lists of interventions were presented by their relevance to high-income countries and low–middle-income countries. Results In phase 1, 43 interventions were identified, which had low uptake in practice according to 3042 professionals globally. In phase 2, a shortlist of 15 intervention domains was generated. In phase 3, interventions were deemed acceptable for more than 90 per cent of patients except for reducing general anaesthesia (84 per cent) and re-sterilization of ‘single-use’ consumables (86 per cent). In phase 4, the top three shortlisted interventions for high-income countries were: introducing recycling; reducing use of anaesthetic gases; and appropriate clinical waste processing. In phase 4, the top three shortlisted interventions for low–middle-income countries were: introducing reusable surgical devices; reducing use of consumables; and reducing the use of general anaesthesia. Conclusion This is a step toward environmentally sustainable operating environments with actionable interventions applicable to both high– and low–middle–income countries

Carbonate diagenesis in a high transmissivity coastal aquifer, Biscayne Aquifer, southeastern Florida, USA

Cores collected through the Biscayne Aquifer (Plio-Pleistocene) in Hollywood, southeastern Florida, as part of the Hollywood Coastal Salinity Barrier Project provided an opportunity to examine the diagenesis of limestones and sandstones at the meteoric to marine water transition of one of the most transmissive aquifers in the world. The saline water front, and thus coastal mixing zone, has migrated landward approximately 1 km in the Hollywood area as the result of wellfield withdrawals. No changes in mineralogy (such as dolomitization), cement types and abundances, paragenetic sequence, or porosity are evident that can be correlated with the current or likely pre-development (wellfield withdrawals) location of the mixing zone. An approximately 2parts per thousand downhole increase in calcite delta(18)O values is present in a core (HMW-6D) that penetrates the pre-development mixing zone, which may be related to either a down hole increase in salinity or to the interaction of meteoric waters with marine carbonate sediments during calcite cementation. The Biscayne Aquifer in Hollywood is currently a relatively quiescent diagenetic environment. The limited current diagenesis appears to consist of the dissolution of trace skeletal aragonite remaining in the aquifer, as suggested by a meteoric water Sr/Ca ratio similar to that of molluscan aragonite. It is proposed that a 'punctuated equilibria' model may be applicable to diagenesis in the Biscayne and other aquifers, in which limestones and sandstones entered a long period of diagenetic stasis after a period of relatively rapid textural and mineralogical stabilization

Peripancreatic Fat Invasion Is an Independent Predictor of Poor Outcome Following Pancreaticoduodenectomy for Pancreatic Ductal Adenocarcinoma

Background Following pancreaticoduodenectomy for pancreatic ductal adenocarcinoma (PDAC), identification of peripancreatic fat tumor invasion promotes a tumor to stage T3. We sought to understand better the impact of histological peripancreatic fat invasion on prognosis and site of recurrence in a cohort of patients with PDAC. Methods We analyzed the patient demographics, outcome, and recurrence data that had been prospectively collected in 189 consecutive PDAC undergoing potentially curative pancreaticoduodenectomy between 1996 and 2009. Pathological features were reassessed for all patients. Survival outcome was compared using Kaplan-Meier/Cox proportional hazards analysis. The primary site of recurrence was defined as either locoregional or distant metastases. Results The median survival of this PDAC cohort was 18.9 months (95% confidence interval (CI) 15.7-22.2). Histological peripancreatic fat invasion was evident in 51 (27%) patients and was associated with lymph node metastases (p=0.004) and larger tumor size (p=0.015). The presence of peripancreatic fat invasion was associated with reduced overall survival following resection (12.4 months [95% CI 9.9-15.0]) when compared to those patients with no evidence of fat invasion (22.6 months [95% CI 18.5-26.7]; p < 0.0001). By multivariate survival analysis, independent predictors of overall survival included tumor grade (p=0.002), lymph node involvement (p=0.025), resection margin status (p=0.003), venous invasion (p=0.045), and peripancreatic fat invasion (p=0.007). Invasion into the pancreatic fat was significantly associated with the primary site of recurrence being locoregional failure (p=0.002). Conclusions Peripancreatic fat invasion was identified as being an independent predictor of poor outcome following pancreaticoduodenectomy for PDAC. Additionally, the presence of peripancreatic fat invasion was associated with locoregional disease as the primary site of recurrence. This may have implications for the staging of PDAC and potentially require incorporation into future staging systems to improve outcome stratification
