Patient falls: Association with hospital Magnet status and nursing unit staffing.

The relationships between hospital Magnet® status, nursing unit staffing, and patient falls were examined in a cross-sectional study using 2004 National Database of Nursing Quality Indicators (NDNQI®) data from 5,388 units in 108 Magnet and 528 non-Magnet hospitals. In multivariate models, the fall rate was 5% lower in Magnet than non-Magnet hospitals. An additional registered nurse (RN) hour per patient day was associated with a 3% lower fall rate in ICUs. An additional licensed practical nurse (LPN) or nursing assistant (NA) hour was associated with a 2-4% higher fall rate in non-ICUs. Patient safety may be improved by creating environments consistent with Magnet hospital standards.
Treatment of midportion Achilles tendinopathy: an evidence-based overview

In Achilles tendinopathy, differentiation should be made between paratendinopathy, insertional- and midportion Achilles tendinopathy. Midportion Achilles tendinopathy is clinically characterized by a combination of pain and swelling at the affected site, with impaired performance as an important consequence. The treatment of midportion Achilles tendinopathy contains both non-surgical and surgical options. Eccentric exercise has shown to be an effective treatment modality. Promising results are demonstrated for extracorporeal shockwave therapy. In terms of the surgical treatment of midportion Achilles tendinopathy, no definite recommendations can be made. IV.
One-year results of a prospective, randomised clinical trial comparing four meshes in laparoscopic inguinal hernia repair (TAPP)

A low rate of chronic pain and maximum postoperative comfort are the main goals today in inguinal hernia repair. This four-arm randomised trial compares these parameters after laparoscopic hernia repair (TAPP) with a standard heavyweight mesh (HW), a pure middleweight polypropylene mesh (MW), a lightweight composite polypropylene mesh (LW), or a titanised lightweight mesh (TLW). The primary endpoint of the study was the incidence of chronic pain of any severity at the site of hernia repair at 1 year. A total of 600 patients with a laparoscopic inguinal hernia repair and a defect diameter of 3–5 cm were included in the trial. In all patients, a non-invasive mesh fixation technique was performed using fibrin glue. Patients were assessed for pain, foreign body sensation, and physical activities preoperatively, early postoperatively, at 4 weeks, at 6 months, and at 1 year by questionnaire, and were examined clinically. Postoperatively, seroma formation was measured by ultrasound. At 1 year after TAPP, frequency of pain did not differ statistically between the four groups (depending on type of activity: between 6–8% with HW mesh, 2–4% with middleweight mesh, and 2–4.7% with both lightweight meshes); average intensity of pain was very low, at between VAS 0.4 ± 3.1 and 1.5 ± 7.8 (MW, LW, TLW) and between 1.9 ± 8.6 and 2.3 ± 9.1 (HW) depending on activity (n.s.). Early postoperatively between 31.3% (LW) and 21.3% (TLW) of the patients needed pain medication (n.s.); at 1 year this percentage had dropped to 0.3% (one HW, one MW). Foreign body sensation did not differ but impairment of physical activities (P = 0.0437) was significantly less in the MW, LW, and TLW group (6–12.7%) compared to HW (15.3%) at 4 weeks; at 1 year this percentage was between 0 and 1.3% (n.s.). Compared to HW mesh, the use of MW, LW, and TLW meshes for laparoscopic hernia repair did not significantly affect rate of chronic pain, but seemed to improve early postoperative convalescence. No difference was found between middleweight pure polypropylene (MW), composite lightweight (LW), or titanised lightweight polypropylene (TLW) meshes.
Security Aspects of the Extended Playfair Cipher

The well known multiple letter encryption cipher is the Playfair cipher. Here the digrams in the plaintext are treated as single units and converted into corresponding cipher text digrams. However because of the drawbacks inherent in the 5*5 Playfair cipher which adversely affects the security we proposed an 8*8 Playfair cipher and then coupled it with LFSR (Linear Feedback Shift Register) to make the traditional Playfair cipher at par with the advanced ciphers available like AES and DES. For details one can refer to [1]. Now for all practical applications, performance and speed are also prime concerns besides security. The LFSR not only enhances the security up to a considerable level by generating random sequences but also provides a much faster rate of encryption and decryption. This paper deals in with the security issues of the new proposed system. Various types of cryptography attacks have been taken under consideration and the resistance of the proposed cipher to all these attacks has been discussed. At the end we find that the proposed cipher is not vulnerable to attacks.
Private data deduplication protocols in cloud storage

In this paper, a new notion which we call private data deduplication protocol, a deduplication technique for private data storage is introduced and formalized. Intuitively, a private data deduplication protocol allows a client who holds a private data proves to a server who holds a summary string of the data that he/she is the owner of that data without revealing further information to the server. Our notion can be viewed as a complement of the state-of-the-art public data deduplication protocols of Halevi et al [7]. The security of private data deduplication protocols is formalized in the simulation-based framework in the context of two-party computations. A construction of private deduplication protocols based on the standard cryptographic assumptions is then presented and analyzed. We show that the proposed private data deduplication protocol is provably secure assuming that the underlying hash function is collision-resilient, the discrete logarithm is hard and the erasure coding algorithm can erasure up to α-fraction of the bits in the presence of malicious adversaries in the presence of malicious adversaries. To the best our knowledge this is the first deduplication protocol for private data storage.

Adaptive gain sliding mode observer for state of charge estimation based on combined battery equivalent circuit model in electric vehicles

An adaptive gain sliding mode observer (AGSMO) for battery state of charge (SOC) estimation based on a combined battery equivalent circuit model (CBECM) is presented. The errors convergences of the AGSMO for the SOC estimation are proved by Lyapunov stability theory. The AGSMO has a capability of compensating modeling errors caused by the parameters variation of the CBECM and minimizing chattering level in SOC estimation. The lithium-polymer battery (LiPB) is used to conduct experiments for extracting the parameters of the CBECM and verifying the effectiveness of the proposed AGSMO for the SOC estimation.
Using metrics in Agile and Lean Software Development - A systematic literature review of industrial studies

Context: Software industry has widely adopted Agile software development methods. Agile literature proposes a few key metrics but little is known of the actual metrics use in Agile teams. Objective: The objective of this paper is to increase knowledge of the reasons for and effects of using metrics in industrial Agile development. We focus on the metrics that Agile teams use, rather than the ones used from outside by software engineering researchers. In addition, we analyse the influence of the used metrics. Method: This paper presents a systematic literature review (SLR) on using metrics in industrial Agile software development. We identified 774 papers, which we reduced to 30 primary studies through our paper selection process. Results: The results indicate that the reasons for and the effects of using metrics are focused on the following areas: sprint planning, progress tracking, software quality measurement, fixing software process problems, and motivating people. Additionally, we show that although Agile teams use many metrics suggested in the Agile literature, they also use many custom metrics. Finally, the most influential metrics in the primary studies are Velocity and Effort estimate. Conclusion: The use of metrics in Agile software development is similar to Traditional software development. Projects and sprints need to be planned and tracked. Quality needs to be measured. Problems in the process need to be identified and fixed. Future work should focus on metrics that had high importance but low prevalence in our study, as they can offer the largest impact to the software industry.
Dynamic tire friction models for vehicle traction control

In this paper we derive a dynamic friction force model for road/tire interaction for ground vehicles. The model is based on a similar dynamic friction model for contact developed previously for contact-point friction problems, called the LuGre model [4]. We show that the dynamic LuGre friction model is able to accurately capture velocity and road/surface dependence of the tire friction force.
Does Capital Punishment Deter Murder ?

Ethical, philosophical and religious values are central to the continuing controversy over capital punishment. Nevertheless, factual evidence can and should inform policy making. The evidence for capital punishment as an uniquely effective deterrent to murder is especially important, since deterrence is the only major pragmatic argument on the pro-death penalty side.1 The purpose of this paper is to survey and evaluate the evidence for deterrence.
A secure effective key management scheme for dynamic access control in a large leaf class hierarchy

Lo et al. (2011) proposed an efficient key assignment scheme for access control in a large leaf class hierarchy where the alternations in leaf classes are more frequent than in nonleaf classes in the hierarchy. Their scheme is based on the public-key cryptosystem and hash function where operations like modular exponentiations are very much costly compared to symmetric-key encryptions and decryptions, and hash computations. Their scheme performs better than the previously proposed schemes. However, in this paper, we show that Lo et al.’s scheme fails to preserve the forward security property where a security class Cx can also derive the secret keys of its successor classes Cj’s even after deleting the security class Cx from the hierarchy. We aim to propose a new key management scheme for dynamic access control in a large leaf class hierarchy, which makes use of symmetric-key cryptosystem and one-way hash function. We show that our scheme requires significantly less storage and computational overheads as compared to Lo et al.’s scheme and other related schemes. Through the informal and formal security analysis, we further show that our scheme is secure against all possible attacks including the forward security. In addition, our scheme supports efficiently dynamic access control problems compared to Lo et al.’s scheme and other related schemes. Thus, higher security along with low storage and computational costs make our scheme more suitable for practical applications compared to other schemes. 2013 Elsevier Inc. All rights reserved.
The Microcephalin Ancestral Allele in a Neanderthal Individual

BACKGROUND
The high frequency (around 0.70 worldwide) and the relatively young age (between 14,000 and 62,000 years) of a derived group of haplotypes, haplogroup D, at the microcephalin (MCPH1) locus led to the proposal that haplogroup D originated in a human lineage that separated from modern humans >1 million years ago, evolved under strong positive selection, and passed into the human gene pool by an episode of admixture circa 37,000 years ago. The geographic distribution of haplogroup D, with marked differences between Africa and Eurasia, suggested that the archaic human form admixing with anatomically modern humans might have been Neanderthal.


METHODOLOGY/PRINCIPAL FINDINGS
Here we report the first PCR amplification and high-throughput sequencing of nuclear DNA at the microcephalin (MCPH1) locus from Neanderthal individual from Mezzena Rockshelter (Monti Lessini, Italy). We show that a well-preserved Neanderthal fossil dated at approximately 50,000 years B.P., was homozygous for the ancestral, non-D, allele. The high yield of Neanderthal mtDNA sequences of the studied specimen, the pattern of nucleotide misincorporation among sequences consistent with post-mortem DNA damage and an accurate control of the MCPH1 alleles in all personnel that manipulated the sample, make it extremely unlikely that this result might reflect modern DNA contamination.


CONCLUSIONS/SIGNIFICANCE
The MCPH1 genotype of the Monti Lessini (MLS) Neanderthal does not prove that there was no interbreeding between anatomically archaic and modern humans in Europe, but certainly shows that speculations on a possible Neanderthal origin of what is now the most common MCPH1 haplogroup are not supported by empirical evidence from ancient DNA.
M4Cloud - Generic Application Level Monitoring for Resource-shared Cloud Environments

Cloud computing is a promising concept for the implementation of scalable on-demand computing infrastructures, where resources are provided in a self-managing manner based on predefined customers requirements. A Service Level Agreement (SLA), which is established between a Cloud provider and a customer, specifies these requirements. It includes terms like required memory consumption, bandwidth or service availability. The SLA also defines penalties for SLA violations when the Cloud provider fails to provide the agreed amount of resources or quality of service. A current challenge in Cloud environments is to detect any possible SLA violation and to timely react upon it to avoid paying penalties, as well as reduce unnecessary resource consumption by managing resources more efficiently. In resource-shared Cloud environments, where there might be multiple VMs on a single physical machine and multiple applications on a single VM, Cloud providers require mechanisms for monitoring resource and QoS metrics for each customer application separately. Currently, there is a lack of generic classification of application level metrics. In this paper, we introduce a novel approach for classifying and monitoring application level metrics in a resource-shared Cloud environment. We present the design and implementation of the generic application level monitoring system. Finally, we evaluate our approach and implementation, and provide a proof of concept and functionality.
Energy minimization for periodic real-time tasks on heterogeneous processing units

Adopting multiple processing units to enhance the computing capability or reduce the power consumption has been widely accepted for designing modern computing systems. Such configurations impose challenges on energy efficiency in hardware and software implementations. This work targets power-aware and energy-efficient task partitioning and processing unit allocation for periodic real-time tasks on a platform with a library of applicable processing unit types. Each processing unit type has its own power consumption characteristics for maintaining its activeness and executing jobs. This paper proposes polynomial-time algorithms for energy-aware task partitioning and processing unit allocation. The proposed algorithms first decide how to assign tasks onto processing unit types to minimize the energy consumption, and then allocate processing units to fit the demands. The proposed algorithms for systems without limitation on the allocated processing units are shown with an (m+1)-approximation factor, where mis the number of the available processing unit types. For systems with limitation on the number of the allocated processing units, the proposed algorithm is shown with bounded resource augmentation on the limited number of allocated units. Experimental results show that the proposed algorithms are effective for the minimization of the overall energy consumption.

Eban health promotion intervention: conceptual basis and procedures.

OBJECTIVE
This article concerns the health promotion intervention that served as the comparison condition in Project Eban, the NIMH Multisite HIV/STD Prevention Trial for African American Couples. Considerable research has documented the high rates of chronic diseases, including heart disease, cancer, stroke, and diabetes, among African Americans. Many of these diseases are tied to behavioral risk factors-the things that people do or do not do, their diet, the amount of exercise they get, and their substance use practices.


DESIGN
The Eban Health Promotion Intervention was designed to increase healthful behaviors, including physical activity, healthful dietary practices, ceasing cigarette smoking and alcohol abuse, practicing early detection and screening behaviors, and improving medication adherence. As a comparison condition, the Eban Health Promotion Intervention was designed to be structurally similar to the Eban HIV/STD Risk Reduction Intervention.


METHODS
This article describes the intervention and how it was developed, integrating social cognitive theory with information collected in formative research to ensure that the intervention was appropriate for African Americans affected by HIV.


CONCLUSION
Project Eban not only tests the efficacy of an HIV/STD risk reduction intervention for African American serodiscordant couples, but also tests the efficacy of an intervention addressing many of the other health problems common in this population.
What do medical outpatients attending a neurology clinic think about antidepressants?

OBJECTIVE
To determine how medical outpatients attending a neurology clinic view antidepressant medication and whether those who present with medically unexplained symptoms have different views than those whose symptoms are explained by neurological disease.


METHODS
A total of 89 consecutive outpatients attending a medical neurology clinic were interviewed.


RESULTS
Those who believed that antidepressants were addictive comprised 74% and those who thought that they could cause physical harm comprised 47%. Only 49% were aware that antidepressants could be used to treat symptoms other than depression. The views of patients whose symptoms were rated by the doctor as being 'not at all' only 'somewhat' unexplained by neurological disease (37% of the total) were neither substantially nor statistically different those whose symptoms were rated as 'largely' or 'completely' explained by neurological disease.


CONCLUSION
The majority of medical patients attending a neurology clinic, and not just those with medically unexplained symptoms, have largely negative beliefs about antidepressant drugs. The implications for patient adherence to these agents and for medical practice are discussed.
Comparison of intramuscular and oral meloxicam in rheumatoid arthritis patients

Objective: This double-blind, double-dummy, two-way comparative trial evaluated the overall efficacy and tolerability of intramuscular (im) vs oral meloxicam.¶Subjects: 346 patients with rheumatoid arthritis (RA).¶Treatment and Methods: 173 patients in each group were randomised to receive either im meloxicam (15 mg) plus a placebo tablet, or oral meloxicam (15 mg) plus a placebo injection for 7 days.¶Results: Significant (p<0.001) improvements in overall pain and disease activity were observed by patients treated with im and oral meloxicam, with no significant difference between treatments. The im formulation was better than the oral tablet in terms of rapidity of action (p=0.012), global efficacy (p=0.030) and duration of morning stiffness (p=0.026). Local tolerability of im meloxicam was very good and comparable with placebo injections.¶Conclusion: Oral and im meloxicam (15 mg) were both effective and well-tolerated for acute exacerbations of RA. The im formulation had some advantages, such as a faster onset of action.¶
Solving Solar Neutrino Puzzle via LMA MSW ConversionThe project supported in part by National Natura

We analyze the existed solar neutrino experiment data and show the allowed regions. The result from SNO’s salt phase itself restricts quite a lot the allowed region’s area. Reactor neutrinos play an important role in determining oscillation parameters. KamLAND gives decisive conclusion on the solution to the solar neutrino puzzle, in particular, the spectral distortion in the 766.3 Ty KamLAND data gives another new improvement in the constraint of solar MSW-LMA solutions. We confirm that at 99.73% C.L. the high-LMA solution is excluded. ∗email: qiuyu@ustc.edu.cn 1
Nerve supply and experimental myotonia in rats

20, 25-Diazacholesterol does not induce myotonia in denervated mammalian skeletal muscle, and cordotomy also renders the muscles resistant to the induction of myotonia. Denervation of muscle already rendered myotonic, has no effect on the intensity of the phenomenon. Finally, tenotomy and posterior rhizotomy leave the myotonic activity in the "deafferentated" muscles unchanged. These findings are discussed in relation to "trophic" influences of the motor pathways on the postsynaptic structures of skeletal muscle.
Reduction in injury rates in nursing personnel through introduction of mechanical lifts in the workplace.

BACKGROUND
Health care workers incur frequent injuries resulting from patient transfer and handling tasks. Few studies have evaluated the effectiveness of mechanical lifts in preventing injuries and time loss due to these injuries.


METHODS
We examined injury and lost workday rates before and after the introduction of mechanical lifts in acute care hospitals and long-term care (LTC) facilities, and surveyed workers regarding lift use.


RESULTS
The post-intervention period showed decreased rates of musculoskeletal injuries (RR = 0.82, 95% CI: 0.68-1.00), lost workday injuries (RR = 0.56, 95% CI: 0.41-0.78), and total lost days due to injury (RR = 0.42). Larger reductions were seen in LTC facilities than in hospitals. Self-reported frequency of lift use by registered nurses and by nursing aides were higher in the LTC facilities than in acute care hospitals. Observed reductions in injury and lost day injury rates were greater on nursing units that reported greater use of the lifts.


CONCLUSIONS
Implementation of patient lifts can be effective in reducing occupational musculoskeletal injuries to nursing personnel in both LTC and acute care settings. Strategies to facilitate greater use of mechanical lifting devices should be explored, as further reductions in injuries may be possible with increased use.
