The present review paper provides a systematic insight into the studies published so far when it comes to the research on the cost and performance optimisation in the parcel delivery phase. Globalisation, as well as the new trends, such as selling online, directly influences the demands for the delivery of goods. Demand for the delivery of goods proportionally affects the transport prices. A great majority of deliveries is carried out in densely populated urban areas. In terms of costs, the greatest part in the courier organisations costs is observed in the technological phase of parcel delivery, which is at the same time the least efficient. For that reason, significant improvement of performance and cost optimisation in the very delivery phase is a rather challenging field for the researchers. New algorithm-based technologies, innovations in the logistics and outsourcing of individual technological phases are ways by means of which one strives to enhance the delivery efficiency, to improve performance and quality, but also - to optimise the costs in the last phase of delivery. The aim of the present paper is to offer a systematic review into the most recent research in the field of technology, innovations and outsourcing models with the aim of reducing the cost and enhancing the productivity and quality in parcel delivery.

As Hyland, Lee, and Mills (2015) note, many conceptualizations of mindfulness include three characteristics. In particular, mindfulness is often defined as a state of consciousness in which an individual (a) focuses on the present moment, (b) attends to phenomena occurring both externally and internally, and (c) remains open to and accepting of observed stimuli—and thus avoids making judgments. Together, these characteristics grant insight into how mindfulness stands to improve performance in work settings. Just as directing attention to the work environment and the tasks and events associated with it can equip workers with key information for making decisions and help them identify and circumvent risks and threats, so too can attending to internal phenomena (e.g., emotions and intuitions) provide workers with useful inputs to the decisions they face (Dane, 2011). Furthermore, in refraining from making judgments and evaluations, workers are more likely to view unfolding events through a variety of lenses and are less likely to view their thoughts, feelings, and reactions as manifestations or indictments of who they are (Glomb, Duffy, Bono, & Yang, 2011). In line with these observations, researchers have hypothesized and provided evidence for positive relationships between mindfulness and the well-being and performance of workers (e.g., Allen & Kiburz, 2012; Dane & Brummel, 2014; Hülsheger, Alberts, Feinholdt, & Lang, 2013).

Urban impervious areas provide a guaranteed source of runoff, especially in cities with high rainfall – this represents a source of water with low sensitivity to unfavourable climate change. Whilst the potential to reuse stormwater has long been recognised, its quality has largely limited usage to non-potable applications requiring the use of a third-pipe network, a prohibitively expensive option in established urban areas. Given recent advances in membrane filtration, this study investigates the potential of harvesting and treating stormwater to a potable standard to enable use of the potable distribution network. A case study based on the Throsby Creek catchment in Newcastle explores the issue. The high seasonally uniform rainfall provides insight into the maximum potential of such an option. Multicriterion optimisation was used to identify Pareto optimal solutions for harvesting, storing and treating stormwater. It is shown that harvesting and treating stormwater from a 13 km2 catchment can produce yields ranging from 8.5 to 14.2 ML/day at costs ranging from AU$2.60/kL to AU$2.89/kL, which may become viable as the cost of traditional supply continues to grow. However, there are significant social impacts to deal with including alienation of public land for storage and community acceptance of treated stormwater.

A recent series of experiments suggests that fostering superstitions can substantially improve performance on a variety of motor and cognitive tasks ( Damisch, Stoberock, & Mussweiler, 2010 ). We conducted two high-powered and precise replications of one of these experiments, examining if telling participants they had a lucky golf ball could improve their performance on a 10-shot golf task relative to controls. We found that the effect of superstition on performance is elusive: Participants told they had a lucky ball performed almost identically to controls. Our failure to replicate the target study was not due to lack of impact, lack of statistical power, differences in task difficulty, nor differences in participant belief in luck. A meta-analysis indicates significant heterogeneity in the effect of superstition on performance. This could be due to an unknown moderator, but no effect was observed among the studies with the strongest research designs (e.g., high power, a priori sampling plan).

Objective: The present epidemiological study was conducted with the objectives of providing an insight into the current use of antidiabetic medications to diabetics and hypertensive diabetics in urban areas and determining how the patient factors influence the prescribing of antidiabetic medications. Methodology: Data of patients of past two years were collected from Bangabandhu Sheikh Mujib Medical University (BSMMU) Hospital, Dhaka, Bangladesh. The details were entered in the structured patient profile form. Data were statistically analyzed using the Microsoft Excel 2007 software. Result: A total of 958 patient’s data were collected and analyzed of which 632 (65.97 %) were males and 326 (34.03 %) were females. These patients were further categorized based on their age. 330 patients (34.45 %) belonged to the age group 20 – 44 years, 504 (52.61 %) to the age group 45 – 65 years and 124 (12.94 %) to the age group 65 – 80 years. 684 (71.4%) patients out of the 958 patients studied were suffering from coexisting hypertension. Co-existing hypertension was found to be more prevalent in the age group 45 – 65 years (67.69%) and was found more in females (84.04%). Conclusion: Metformin was the oral hypoglycemic which was the highest prescribed. In hypertensive diabetics Metformin and Pioglitazone were most frequently prescribed drugs. Biguanides and Insulin were the most commonly prescribed antidiabetics. A combination of two or more drugs of different classes was prescribed to hypertensive diabetics. It is necessary to have an improved understanding of the etiology and pathophysiology of diabetes to focus on research efforts appropriately.

The quality of the software can be measured by its return on investment. Factors which may affect the return on investment (ROI) is the tangible factors (such as the cost) dan intangible factors (such as the impact of software to the users or stakeholder). The factor of the software itself are assessed through reviewing, testing, process audit, and performance of software. This paper discusses the consideration of return on investment (ROI) assessment criteria derived from the software and its users. These criteria indicate that the approach may support a rational consideration of all relevant criteria when evaluating software, and shows examples of actual return on investment models. Conducted an analysis of the assessment criteria that affect the return on investment if these criteria have a disproportionate effort that resulted in a return on investment of a software decreased.

Background: Prediction of proteins’ secondary structure is one of the major steps in the generation of homology models. These models provide structural information which is used to design suitable ligands for potential medicinal targets. However, selecting a proper tool between multiple Secondary Structure Prediction (SSP) options is challenging. The current study is an insight into currently favored methods and tools, within various contexts. Objective: A systematic review was performed for a comprehensive access to recent (2013-2016) studies which used or recommended protein SSP tools. Methods: Three databases, Web of Science, PubMed and Scopus were systematically searched and 99 out of the 209 studies were finally found eligible to extract data. Results: Four categories of applications for 59 retrieved SSP tools were: (I) prediction of structural features of a given sequence, (II) evaluation of a method, (III) providing input for a new SSP method and (IV) integrating an SSP tool as a component for a program. PSIPRED was found to be the most popular tool in all four categories. JPred and tools utilizing PHD (Profile network from HeiDelberg) method occupied second and third places of popularity in categories I and II. JPred was only found in the two first categories, while PHD was present in three fields. Conclusion: This study provides a comprehensive insight into the recent usage of SSP tools which could be helpful for selecting a proper tool.

Introduction Lateral condyle fractures are the second most common pediatric elbow fracture. There exist multiple options for internal fixation including buried K-wires, unburied K-wires, and screw fixation. Our study aims to review the current literature and determine if fixation strategy affects outcomes to include fracture union, postoperative range of motion, and need subsequent surgery. Methods A systematic review of Pubmed, MEDLINE, and EMBASE databases was performed. Included articles involve pediatric patients with displaced lateral condyle fractures treated with internal fixation that reported outcomes to include union rates and complications. Results Thirteen studies met inclusion criteria for a total of 1299 patients (472 buried K-wires, 717 unburied K-wires, and 110 screws). The patients’ average age was 5.8 ± 0.6 years, male (64%), and had 16.3 months of follow-up. No differences in union and infection rates were found. Unburied K-wires had the shortest time to union and the greatest elbow range of motion postoperatively. Conclusions Our systematic review demonstrates similar outcomes with union and infection rates between all fixation techniques. Unburied K-wires demonstrated a shorter time to union and the greatest postoperative range of motion. Additionally, unburied K-wires may be removed in clinic, decreasing the cost on the healthcare system. Evidence Level 3.
