Organizational climate configurations: relationships to collective attitudes, customer satisfaction, and financial performance.

Research on organizational climate has tended to focus on independent dimensions of climate rather than studying the total social context as configurations of multiple climate dimensions. The authors examined relationships between configurations of unit-level climate dimensions and organizational outcomes. Three profile characteristics represented climate configurations: (1) elevation, or the mean score across climate dimensions; (2) variability, or the extent to which scores across dimensions vary; and (3) shape, or the pattern of the dimensions. Across 2 studies (1,120 employees in 120 bank branches and 4,317 employees in 86 food distribution stores), results indicated that elevation was related to collective employee attitudes and service perceptions, while shape was related to customer satisfaction and financial performance. With respect to profile variability, results were mixed. The discussion focuses on future directions for taking a configural approach to organizational climate.
A mixed-solvent strategy for facile and green preparation of graphene by liquid-phase exfoliation of graphite

A versatile and scalable mixed-solvent strategy, by which two mediocre solvents could be combined into good solvents for exfoliating graphite, is demonstrated for facile and green preparation of graphene by liquid-phase exfoliation of graphite. Mild sonication of crystal graphite powder in a mixture of water and alcohol could yield graphene nanosheets, which formed a highly stable suspension in the mixed solvents. The graphene yield was estimated as *10 wt%. The optimum mass fraction of ethanol in water–ethanol mixtures and isopropanol in water– isopropanol mixtures was experimentally determined as *40 and *55 % respectively, which could be roughly predicted by the theory of Hansen solubility parameters. Statistics based on atomic force microscopic analysis show that up to*86 % of the prepared nanosheets were less than 10-layer thick with a monolayer fraction of *8 %. High resolution transmission electron microscopy, infrared spectroscopy, X-ray diffraction, and Raman spectrum analysis of the vacuum-filtered films suggest the graphene sheets to be largely free of defects and oxides. The proposed mixed-solvent strategy here extends the scope for liquid-phase processing graphene and gives researchers great freedom in designing ideal solvent systems for specific applications.
The effects of increased therapy time on cognition and mood in frail patients with a stroke who rehabilitate on rehabilitation units of nursing homes in the Netherlands: a protocol of a comparative study

BACKGROUND
Recovery after stroke is dependent on how much time can be spent on rehabilitation. Recently, we found that therapy time for older stroke patients on a rehabilitation unit of a nursing home could be increased significantly from 8.6 to at least 13 hours a week. This increase was attained by the implementation of interventions, focused on strength, mobility and balance. Nurses carried out these exercises with the patients during their daily activities. The aim of the present study is to investigate if increased therapy time has a positive effect on cognition, mood (depression and anxiety), and ADL in stroke patients.


METHODS
A comparative single blind controlled study will be applied. Patients suffering from a stroke and staying on one of the rehabilitation units of the nursing homes are eligible for participation. Participants belong to the intervention group if they stay in two nursing homes where four interventions of the Clinical Nursing Rehabilitation Stroke Guideline were implemented. Participants who stay in two nursing homes where therapy is given according to the Dutch stroke Guideline, are included in the control group. Clinical neuropsychologists will assess patients' cognitive functioning, level of depression (mood) and anxiety. Nurses will assess a Barthel Index score on a weekly basis (ADL). These variables are measured at baseline, after 8 weeks and at the moment when participants are discharged from the nursing home.


DISCUSSION
The present study evaluates the effect of increased therapy time on cognition, mood (level of depression and anxiety), and ADL in stroke patients. When positive effects will be found this study can guide policy makers and practitioners on how to implement more therapy time on rehabilitation wards of nursing homes.

Socioeconomic Status and Prevalence of Obesity and Diabetes in a Mexican American Community, Cameron County, Texas, 2004-2007

INTRODUCTION
Mexican Americans are at increased risk for obesity and diabetes. We established a cohort on the United States-Mexico border to determine the prevalence of obesity and diabetes in this Mexican American population and to see whether minor economic advantages had any effect on health.


METHODS
We randomly selected and extensively documented 810 people aged 35 to 64 years. Weighted data were analyzed to establish prevalence of obesity and diabetes and other markers of poor health such as elevated glycated hemoglobin levels.


RESULTS
Rates of obesity (body mass index > or = 30 kg/m(2)) were 57% in the first (lower) of 4 socioeconomic strata by income and were 55.5% in the third (higher). People in the higher socioeconomic stratum were significantly less likely to have undiagnosed diabetes (2% vs 9%). Among people aged 55 to 64 years, rates of diabetes were significantly higher among those in the lower socioeconomic stratum than among those in the higher stratum. Rates of undiagnosed diabetes had similar differences. Approximately three-fourths of the respondents reported having no health insurance, and we found no difference between people in different socioeconomic strata.


CONCLUSION
Rates of obesity and diabetes in this border community are among the highest in the United States. Belonging to the lower socioeconomic stratum significantly increased the likelihood of having undiagnosed diabetes and, in patients too young to be eligible for Medicare, the overall risk of developing diabetes. Modest improvement in income has a beneficial effect on health in this racial/ethnic minority community.
Metronidazole in the treatment of chronic radiation proctitis: clinical trial.

AIM
To evaluate the effectiveness of metronidazole in combination with corticosteroids in enema and mesalazine (5-aminosalicylic acid) in comparison with the same protocol without metronidazole in the treatment of chronic radiation proctitis.


METHODS
Sixty patients with rectal bleeding and diarrhea were randomly divided into two groups. Patients in the first group were treated with metronidazole (3x400 mg orally per day), mesalazine (3x1 g orally per day), and betamethasone enema (once a day during 4 weeks). Patients in the second group were treated with mesalazine and betamethasone enema, but without metronidazole. The efficacy of metronidazole was assessed on the basis of rectal bleeding, diarrhea, and rectosigmoidoscopy findings in all patients.


RESULTS
The incidence of rectal bleeding and mucosal ulcers was significantly lower in the metronidazole group, 4 weeks (p=0.009), 3 months (p=0.031), and 12 months (p=0.029) after therapy. There was also a significant decrease in diarrhea and edema in the metronidazole group, 4 weeks (p=0.044), 3 months (p=0.045), and 12 months (p=0.034) after treatment.


CONCLUSION
Metronidazole in combination with mesalazine and betamethasone enemas successfully treats rectal bleeding and diarrhea in chronic radiation proctitis.
Robot global path planning overview and a variation of ant colony system algorithm

This paper presents the results of a research that aims to develop an algorithm to solve robot path planning (RPP) problems in static environments. The problem is to find a global optimal path that satisfies the optimization criteria of shortest path with minimum computation time. A description of a variation of Ant Colony System (ACS) algorithm utilized for Robot Path Planning (RPP) purposes is presented. A representation of heuristic and visibility equation of state transition rules is proposed to sustain the function of Ant Colony System (ACS) for solving RPP problem of finding the optimal path. This algorithm was applied within a global static map that consists of feasible free space nodes. The performance of the algorithm in terms of computation time and number of iteration required to obtain an optimal path were evaluated by using a simulation approach. Subsequently, its performance was compared to the performance of Genetic Algorithm (GA) a well known and established RPP algorithm. The results obtained indicate that the developed algorithm performed much better than the GA. In addition, an overview of robot path planning (PP) algorithms in global static environment is also offered. Keywords—Path Planning, Ant Colony System, Algorithm, Global Environment, Autonomous Robot.
The effectiveness and safety of amisulpride in Chinese patients with schizophrenia: An 8‐week, prospective, open‐label, multicenter, single‐arm study

INTRODUCTION
This study evaluated the effectiveness and safety of amisulpride in Chinese schizophrenia patients.


METHODS
A multicenter, single-arm Phase IV study (NCT01795183). Chinese patients with schizophrenia received amisulpride for 8 weeks. The primary endpoint was ≥50% decrease in Positive and Negative Syndrome Scale total score from Baseline to Week 8.


RESULTS
A total of 316 patients were enrolled; 295 were included in the effectiveness analysis; 66.8% (197/295) achieved ≥50% decrease in Positive and Negative Syndrome Scale total score from Baseline to Week 8. Nine patients discontinued treatment because of adverse events.


DISCUSSION
Amisulpride had clinical effectiveness and was relatively well tolerated in Chinese patients with schizophrenia.
Hard and soft constraints for reasoning about qualitative conditional preferences

Many real life optimization problems are defined in terms of both hard and soft constraints, and qualitative conditional preferences. However, there is as yet no single framework for combined reasoning about these three kinds of information. In this paper we study how to exploit classical and soft constraint solvers for handling qualitative preference statements such as those captured by the CP-nets model. In particular, we show how hard constraints are sufficient to model the optimal outcomes of a possibly cyclic CP-net, and how soft constraints can faithfully approximate the semantics of acyclic conditional preference statements whilst improving the computational efficiency of reasoning about these statements.
The Omega-Project--a comparison of two diagnostic strategies for risk- and cost-oriented management of dyspepsia.

OBJECTIVES
In dyspepsia few data are available from the primary care setting on how selective, risk-factor-oriented endoscopy compares with mandatory endoscopy in the diagnostic outcome and in direct and secondary costs. We studied this in a two-armed multicentre trial (omega-project) with primary care physicians.


MATERIAL AND METHODS
Patients were enrolled and treated by primary care physicians and referred to a gastroenterologist for upper gastrointestinal endoscopy (UGE). Patients were enrolled in the study if they had had epigastric complaints for more than 1 month and no obvious signs or history of organic disease. In the first arm of the study endoscopy was mandatory, in the second selective, i.e. according to a predefined risk profile. Patients enrolled were treated with prokinetic drugs for 2 months. A further indication for endoscopy was non-response to treatment (reduction of the initial symptoms score by less than two-thirds) in the study with selective endoscopy and relapse within the 2-month follow-up period in both studies. The direct costs from number of consultations with the primary care physician, UGEs, number of prescriptions per patient and also absenteeism in days per week were carefully registered in both groups.


RESULTS
All 172 patients of the mandatory endoscopy study and 203/656 patients enrolled in the selective endoscopy study had an UGE (125 at admission, 78 in the follow-up period). Patients were treated for 4 weeks (cisapride or domperidone) and thereafter followed for 8 weeks, at the end of the observation period the response rates were 80% and 79%, respectively. The prevalence of gastric cancers was similar in both groups (> 1%) but extrapolation from the data collected with compulsory endoscopy suggests that two-fifths of the anticipated peptic lesions remained undetected by following the selective strategy. The cost analysis revealed a 31% cost reduction with the selective strategy--in the Swiss cost system--through a reduction in the number of endoscopies by 67%.


CONCLUSION
Selective UGE is cheaper and appears not to compromise the response to prokinetics; however, its diagnostic power is less than with mandatory UGE.

Patterns of care study of radiation therapy for cervix cancer in Japan: the influence of the stratification of institution on the process.

BACKGROUND
To improve the quality of radiation oncology in Japan, Patterns of Care Study (PCS), a widely known quality assurance (QA) program in the USA, was introduced. The feasibility was tested by collecting nationwide data by extramural audit for cervix cancer.


METHODS
From July 1996 through February 1997, PCS audits were performed for 29 institutions nationwide. On the basis of the facility survey by Tsunemoto, 13 institutions were classified as A1 (university hospital/cancer center), 10 as B1 (other institutions treating >120 patients/year) and six as B2 (other institutions treating <120 patients/year). Medical charts for the patients treated for cervix cancer between 1992 and 1994 were reviewed based on the data format of the US PCS. The total number of patients surveyed was 432.


RESULTS
Simulation was used for >90% of the patients in both A1 and B1-2 institutions. However, in B1-2, planning for 5% of the patients was performed with only a clinical set-up (p = 0.0287). A daily fraction with a size of 200 cGy was given to >65% of patients in A1 and to <47% in B1-2. On the other hand, >50% of those in B1-2 were treated with daily fractions of 180 cGy and less compared with 25% in A1 institutions (p < 0.0001). Brachytherapy was utilized more frequently for patients in Stages II (p = 0.0365), III (p = 0.0015) and IV (p = 0.0483) in A1 than in B1-2. As for external beam equipment, linear accelerators with 10 MV or more were used for 83% of the patients in A1. However, in B1-2 institutions, machines with lower energy were used for 38% of the patients (p < 0.0001). The median number of full-time-equivalent (FTE) radiation oncologists was 2.7 in A1, 0.65 in B1 and 0.2 in B2.


CONCLUSIONS
Institutional stratification, including equipment and personnel, was found to affect significantly the patterns of care for cervix cancer. Therefore, to improve the quality of radiation therapy nationwide, improvements in equipment and in supply of FTE personnel are extremely important. PCS was found to have great potential for a practical evaluation of how much improvement will be required in Japan.
Opinion Mining and Sentiment Analysis : A Survey

Opinion Mining and Sentiment Analysis is the field of study that analyzes customer opinions, feedback, sentiments, evaluations, attitudes, and emotions from written language. It is one of the most active research areas in Natural Language Processing (NLP) and is also widely studied in data mining, Web mining, and text mining. The growing importance of sentiment analysis coincides with the growth of social media and Web 2.0 technologies such as reviews, discussion forums, blogs, micro-blogs, and social networks. For the first time in human history, we now have a huge volume of opinionated data recorded in digital form for analysis. In this paper we do a survey of papers on Opinion Mining and Sentiment Analysis and detail the techniques used.
Comparison of costs of care between patients with Alzheimer's disease and dementia with Lewy bodies

BACKGROUND
The objective of this study was to compare total costs of care and its major components for community-living patients with Alzheimer's disease (AD) or dementia with Lewy bodies (DLB). This cross-sectional analysis of baseline data from the Predictors II Study took place in three university-based AD centers in the U.S.


METHODS
Community-living patients clinically diagnosed with probable AD (n = 170) or DLB (n = 25) with a modified Mini-Mental State examination (mMMS) score > or =30, equivalent to a score of approximately > or =16 on the Folstein Mini-Mental State Examination (MMSE), participated in this study. Patient and informant reported on patients' use of direct medical care, direct nonmedical care, and informal care. Patients' clinical and demographic characteristics included global cognitive status (measured by MMSE), functional capacity (measured by Blessed Dementia Rating Scale), psychotic symptoms, behavioral problems, depressive symptoms, extrapyramidal signs, comorbidities, age, and sex. Costs were compared by using covariate matching methods.


RESULTS
Unadjusted total costs and direct medical costs were not significantly different between AD and DLB patients. Compared with AD patients, unadjusted indirect costs were significantly higher and unadjusted direct nonmedical costs were significantly lower among DLB patients. After adjusting for age, sex, cognitive and functional status, differences in all cost components between DLB and AD patients were no longer statistically significant.


CONCLUSIONS
Apparent cost differences were largely attributed to differences in patients' cognitive and functional status. However, the small sample size for DLB patients might have limited power to detect statistically significant differences in costs of care between these groups.
Software Security in Practice

This department is about building software with security in mind. Since it began in 2004, it has focused on the kinds of activities that constitute a secure development life cycle. As of to day, we're broadening that charter to include all the essential ingredients of a sustained soft ware security initiative. Instead of focusing on one turn of the crank that yields one new piece of software, we'll consider the ongoing organizational commitments necessary to facilitate se cure software development.
PKC-mediated GABAergic enhancement of dopaminergic responses: implication for short-term potentiation at a dual-transmitter synapse.

Transmitter-mediated homosynaptic potentiation is generally implemented by the same transmitter that mediates the excitatory postsynaptic potentials (EPSPs), e.g., glutamate. When a presynaptic neuron contains more than one transmitter, however, potentiation can in principle be implemented by a transmitter different from that which elicits the EPSPs. Neuron B20 in Aplysia contains both dopamine and GABA. Although only dopamine acts as the fast excitatory transmitter at the B20-to-B8 synapse, GABA increases the size of these dopaminergic EPSPs. We now provide evidence that repeated stimulation of B20 potentiates B20-evoked dopaminergic EPSPs in B8 apparently via a postsynaptic mechanism, and short-term potentiation of this synapse is critical for the establishment and maintenance of an egestive network state. We show that GABA can act postsynaptically to increase dopamine currents that are elicited by direct applications of dopamine to B8 and that dopamine is acting on a 5-HT3-like receptor. This potentiation is mediated by GABAB-like receptors as GABAB-receptor agonists and antagonists, respectively, mimicked and blocked the potentiating actions of GABA. The postsynaptic actions of GABA rely on a G protein-mediated activation of PKC. Our results suggest that the postsynaptic action of cotransmitter-mediated potentiation may contribute to the maintenance of the egestive state of Aplysia feeding network and, in more general terms, may participate in the plasticity of networks that mediate complex behaviors.
Effectiveness of Road Ripping in Restoring Infiltration Capacity of Forest Roads

Many forest roads are being closed as a step in watershed restoration. Ripping roads with subsoilers or rock rippers is a common practice to increase the infiltration capacity of roads prior to closure. When considering the effectiveness of ripping for reducing runoff and erosion and the potential reduction in slope stability by saturating road fills, it is important to know how ripping changes the infiltration capacity of forest roads. Hydrographs from simulated rainfall on 1-m x 1-m plots were analyzed to find the saturated hydraulic conductivity, an indicator of infiltration capacity. I examined saturated hydraulic conductivity for three treatments on two different soils. One road was built in a soil derived from the metamorphic belt series geology of northern Idaho, a soil noted for its high rock fragment content. The second road was built in a sandy soil derived from decomposed granitics of the Idaho batholith. On each soil, five plots were installed on a road prior to ripping, and nine plots were installed on the same road segment following ripping, four covered with a heavy straw mulch and five without. Three half-hour rainfall events with intensities near 90 mm/hr were simulated on each plot. Results show that ripping increases hydraulic conductivities enough to reduce risk of runoff but does not restore the natural hydraulic conductivity of a forested slope. The unripped road surfaces had hydraulic conductivities in the range of 0-4 mm/hr, whereas ripped roads were in the range of 20-40 mm/hr after the second event. Surface sealing and tilled soil subsidence processes are important in reducing the hydraulic conductivity of the soils with repeated wetting. Subsidence appears to be important on the granitic soil, whereas surface sealing was more important on the belt series soil.
