Implementación y uso de indicadores de gestión en el área logística como herramienta para toma de decisiones

Implementation and use of indicators in logistics management as a tool for decision making is a review paper that establishes whether the use of performance indicators in logistics, adds rigidity and little reaction to new variables. This paper analyzes the performance indicators have two interpretations: The first states that its implementation makes the rigid organization and unable to react to unexpected changes; the second, on the premise that its use supports decision-making processes as dotting the self-organization, seeking effectiveness and continuous improvement processes. In this sense, it is intended to review the management indicators for the logistics area, its uses, benefits and impacts within the operation and secondly, the results of a short interview with experts in logistics will be displayed on their opinions, contributions, advantages and disadvantages of using indicators. Finally the results when comparing the theory with practice will show.
Effect of Instantaneous Performance Feedback During 6 Weeks of Velocity-Based Resistance Training on Sport-Specific Performance Tests

Randell, AD, Cronin, JB, Keogh, JWL, Gill, ND, and Pedersen, MC. Effect of instantaneous performance feedback during 6 weeks of velocity-based resistance training on sport-specific performance tests. J Strength Cond Res 25(1): 87-93, 2011-The purpose of this study was to investigate the effect of instantaneous performance feedback (peak velocity) provided after each repetition of squat jump exercises over a 6-week training block on sport-specific performance tests. Thirteen professional rugby players were randomly assigned to 1 of 2 groups, feedback (n = 7) and non-feedback (n = 6). Both groups completed a 6-week training program (3 sessions per week) comprising exercises typical of their normal preseason conditioning program. Squat jumps were performed in 2 of the 3 sessions each week during which both groups performed 3 sets of 3 concentric squat jumps using a barbell with an absolute load of 40 kg. Participants in group 1 were given real-time feedback on peak velocity of the squat jump at the completion of each repetition using a linear position transducer and customized software, whereas those in group 2 did not receive any feedback. Pre and posttesting consisted of vertical jump, horizontal jump, and 10-/20-/30-m timed sprints. The relative magnitude (effect size) of the training effects for all performance tests was found to be small (0.18-0.28), except for the 30-m sprint performance, which was moderate (0.46). The probabilities that the use of feedback during squat jump training for 6 weeks was beneficial to increasing performance of sport-specific tests was 45% for vertical jump, 65% for 10-m sprints, 49% for 20-m sprints, 83% for horizontal jump, and 99% for 30-m sprints. In addition to improvements in the performance of sport-specific tests, suggesting the potential for greater adaptation and larger training effects, the provision of feedback may also be used in applications around performance targets and thresholds during training.
A comparison of pain assessment by physicians, parents and children in an outpatient setting

Introduction Our objective was to compare pain assessments by patients, parents and physicians in children with different medical conditions, and analyse how this affected the physicians' administration of pain relief. Patients and methods This cross-sectional study involved 243 children aged 3–15 years treated at Bergen Accident and Emergency Department (ED) in 2011. The child patient's pain intensity was measured using age-adapted scales while parents and physicians did independent numeric rating scale (NRS) assessments. Results Physicians assessed the child's mean pain to be NRS=3.2 (SD 2.0), parents: NRS=4.8 (SD 2.2) and children: NRS=5.5 (SD 2.4). The overall child–parent agreement was moderate (Cohen's weighted κ=0.55), but low between child–physician (κ=0.12) and parent–physician (κ=0.17). Physicians significantly underestimated pain in all paediatric patients ≥3 years old and in all categories of medical conditions. However, the difference in pain assessment between child and physician was significantly lower for fractures (NRS=1.2; 95% CI 0.5 to 2.0) compared to wounds (NRS=3.4; CI 2.2 to 4.5; p=0.001), infections (NRS=3.1; CI 2.2 to 4.0; p=0.002) and soft tissue injuries (NRS=2.4; CI 1.9 to 2.9; p=0.007). The physicians’ pain assessment improved with increasing levels of pain, but only 42.1% of children with severe pain (NRS≥7) received pain relief. Conclusions Paediatric pain was significantly underestimated by ED physicians. In the absence of a self-report from the child, parents' evaluation should be listened to. Despite improved pain assessments in children with fractures and when pain was perceived to be severe, it is worrying that barely half of the children with severe pain received analgesics in the ED.
Future hepatitis C virus treatment: interferon‐sparing combinations

An estimated million people have chronic hepatitis C virus (HCV) infection. With current treatment success rates, by 2030, more than 40% will be cirrhotic and the number of cases with end‐stage liver disease is projected to treble. Current standard‐of‐care is the combination of pegylated interferon plus ribavirin for 24–48 weeks. Unfortunately this is associated with poor efficacy (45% in HCV GT1; 75% in GT2 and 65% in GT 3) and tolerability. Many patients are either unsuitable for or decline current treatment infection because of the significant side‐effects associated with this treatment, including those with decompensated cirrhosis or sever psychiatric illness. It is hoped that the development of direct acting antiviral agents (DAAs) will address this huge unmet medical need. The addition of a protease inhibitor to pegylated interferon plus ribavirin is associated with increase in efficacy and shortened duration of therapy in patients with HCV GT1 and is likely to become the new standard‐of‐care. However, triple therapy will not be suitable for patients with non‐1 HCV infection, or contraindications to interferon. It is hoped that the combination of multiple DAAs which target different steps of HCV replication should provide interferon‐free treatment regimen. Current and planned studies will determine which combination (protease, nonnucleoside polymerase, nucleoside polymerase, NS5A, cyclophyllin B inhibitors), how many DAAs and duration of therapy will be required to optimise cure. It will also be important to minimise the emergence of multi‐resistance, which would jeopardise future retreatment options
Intratypic and intertypic specificity of lymphocytes involved in the recognition of herpes simplex virus glycoproteins

Cytotoxic T lymphocytes (CTL) were generated in C57BL/6 mice with herpes simplex virus type 1 (HSV-1) (strains KOS, 17, HFEM, and mP) and HSV-2 (strains 186, G, and GP6). Effector lymphocytes were tested for cytotoxicity against syngeneic HSV-1- and HSV-2-infected cells in a 5-h 51Cr release assay. HSV-1 strain HFEM was found to induce CTL efficiently only when 100-fold more virus was used as compared with HSV-1 strains KOS, 17, and mP. All HSV-1 and HSV-2 strains induced cross-reactive populations of CTL. CTL generated by HSV-1 KOS and HSV-2 186 also demonstrated cross-reactivity in an ear-swelling model for delayed-type hypersensitivity. Lymphocytes generated by all HSV-2 strains were highly efficient at lysing HSV-1-infected target cells. However, HSV-2-infected target cells were found to be less susceptible to lysis by either HSV-1 or HSV-2 CTL than were HSV-1-infected target cells. The lowered susceptibility of HSV-2-infected cells was not due to an inefficient infection of BL/6 WT-3 cells as measured by standard growth assays and infectious center assays. Varying the multiplicity of infection or the time of infection did not increase the susceptibility of HSV-2-infected target cells to lysis by CTL. Increasing the effector-to-target-cell ratio resulted in an increased lysis of both HSV-1- and HSV-2-infected target cells by CTL, but the level of HSV-2-infected target cell lysis still did not approach the level of HSV-1-infected target cell lysis. HSV-2-infected cells were as efficient as HSV-1-infected cells in the cold cell competition assay employed in reducing the lysis of 51Cr-labeled, HSV-1-infected target cells. In addition, HSV-2-infected cells were susceptible to lysis by HSV-immune serum and complement.
OVERBOOKING MODELS FOR HOTEL REVENUE MANAGEMENT

Revenue Management (RM) is an essential strategy for industries having fixed perishable resources to maximize overall revenue by allocating the available resources to the right customers at the right price at the right time. Overbooking is one of the RM tools for hotel revenue management that helps a hotel manager to decide when and how much extra number of rooms to sell. Overbooking arises as some of the customers may not eventually show up (so called “no show”) on the booking date, while others may cancel or amend their bookings in the last minutes. The objective of this paper is to develop overbooking models to determine the optimal number of overbooking for hotels having one and two different types of rooms. We prove that for hotels with only one type of room, there exists a closed form solution to guarantee the optimal number of overbooking, depending on the cost of walking customers to other hotels, the cost of unsold rooms and cancelation distribution observed in the past. For hotels with two types of room, we prove the convexity structure and identify equations to seek the number of overbooking for low-price and high-price rooms. We also provide key comparative statics on how model parameters impact the optimal decisions under different scenarios.
Typologies of the cultural position of drinking.

OBJECTIVE Typologies of the cultural position of drinking from the social science literature are reviewed. METHOD The article reviews significant studies and literature on the topic. RESULTS Starting in the 1940s, two research traditions considered variations in the cultural position of drinking as explanations of rates of drinking problems. A "holocultural" tradition coded and analyzed ethnographic data on tribal and village societies, starting in the 1940s, with each study identifying a different social dimension as crucial. A "sociocultural" tradition distinguished abstinent cultures from prescriptive cultures, in which drinking was integrated with daily life, and expected, but drunkenness was prohibited. These types were implicitly contrasted with American drinking, which was variously characterized. Other dimensional and typological approaches in the literature are considered, including a little-known Jellinek typology. Problems with the widely used distinction between "wetter" and "drier" (or "temperance") cultures are discussed. CONCLUSIONS Four ideal types of the cultural position of drinking can be readily distinguished: abstinent societies, constrained ritual drinking, banalized drinking and fiesta drunkenness. A large residual category remains, however, and a dimensional approach to typology building may be more fruitful. Two basic dimensions are proposed--regularity of drinking and extent of drunkenness--and further dimensions are described that may be added to fit the requirements of the particular study.
The influence of addiction risk on nursing students' expectations of patients' pain reports: a clinical vignette approach.

OBJECTIVE To examine the influence of addiction risk (substance abuse history [SAH]) and pain relief (PR) on nursing and non-nursing students' perceptions of pain in a postoperative vignette patient. METHODS Using a 2 x 2 design, the independent variables SAH (present/+, absent/-) and PR (adequate, little) were varied systematically to produce four vignettes. Participants were randomly assigned to receive one of the four vignettes that described a 45-year-old man after a total hip replacement. Participants rated the vignette patient's experienced and reported pain intensity (PI) on a 0 mm to 100 mm visual analogue scale and addiction risk on a 0 mm to 100 mm visual analogue scale. A pain congruence (PC) score was calculated (PC = reported PI -- experienced PI), and was interpreted as congruent (+/-2 mm) or incongruent (+2 mm to +100 mm for expected pain over-reporting; -2 mm to -100 mm for expected pain under-reporting). RESULTS Responses from undergraduate nursing (n=89) and non-nursing (n=88) students were analyzed. The estimated addiction risk was significantly lower in nursing (14% to 45%) versus non-nursing students (50%). Nursing students' mean PC scores were not significantly altered by SAH alone. Expectations of pain over-reporting were observed under conditions of SAH+/adequate PR, but not SAH+/little PR. In non-nursing students, SAH and PR were significant and independent factors influencing mean PC scores in the direction of pain over-reporting. CONCLUSION Under most conditions, nursing students expected pain under-reporting by the postoperative vignette patient. However, nursing students did expect pain to be over-reported when addiction risk was high and PR was adequate. These data suggest that nursing students' expectations regarding pain over- and under-reporting were sensitive to perceptions of addiction risk, but involved additional factors (eg, level of PR).
Effects of onset asynchrony on pitch perception: adaptation or grouping?

A previous paper by Darwin and Ciocca [J. Acoust. Soc. Am. 91, 3381-3390 (1992)] showed that a slightly mistuned frequency component of a (target) harmonic complex produced smaller pitch shifts in the target if it started 160 ms or more before the other components than if all the components were simultaneous. Three experiments investigated whether this effect of onset asynchrony is due to peripheral adaptation to the leading portion of the mistuned component or to perceptual grouping. The first two experiments showed that the effect of asynchrony could be influenced by grouping mechanisms without changing the amount of adaptation produced by the leading portion of the mistuned component. In the first experiment, the effect of asynchrony was reduced by the presence of an additional (captor) complex which was harmonically related to the mistuned component and synchronous with just its leading portion. In experiment 2, the effect of asynchrony was increased by presenting a captor that was synchronous with the entire mistuned component. This capturing effect was independent of the harmonic relation between the captor and the mistuned component at 40-ms asynchrony; at 160 ms the effect of asynchrony increased further only if the captor and the mistuned component were harmonically related. In the third experiment, the expected amount of adaptation was increased (relative to that produced by a single sine precursor) by presenting several components that were close in frequency to the mistuned component and synchronous with its leading portion.

Degradation Behavior of Lithium-Ion Batteries During Calendar Ageing—The Case of the Internal Resistance Increase

Lithium-ion batteries are regarded as the key energy storage technology for both e-mobility and stationary renewable energy storage applications. Nevertheless, Lithium-ion batteries are complex energy storage devices, which are characterized by a complex degradation behavior, which affects both their capacity and internal resistance. This paper investigates, based on extended laboratory calendar ageing tests, the degradation of the internal resistance of a lithium-ion battery. The dependence of the internal resistance increase on the temperature and state-of-charge level has been extensive studied and quantified. Based on the obtained laboratory results, an accurate semiempirical lifetime model, which is able to predict with high accuracy the internal resistance increase of the lithium-ion battery over a wide temperature range and for all state-of-charge levels, was proposed and validated.
Application of Diagram Methods and Hierarchical Agglomerative Procedures to Assess the Risk of Investment Funds on the Warsaw Stock Exchange

Summary: The issue of the article focuses on the need for the selection of investment funds of the Warsaw Stock Exchange with a certain similarity in terms of investment risk. For this purpose, the selected hierarchical agglomeration procedures and the diagrams methods that allowed creating a map of the funds, describing their diversity and diversity of the market, were applied. In addition, the compatibility of the obtained results were verified in terms of the measures of the investment risks designated by the fund managers.
Afrix Model: An Approach for Measuring and Managing Reputational Risk for African Banks

This research intends to identify corporate reputation drivers and ascertain how African banks brand preference and performance can derived from them using a designed conceptual framework. The methodological approach for the study encompasses a desk research reviewing the existing literature and a qualitative study. The theoretical framework provides a deep understanding of the corporate reputation concept especially dimensions and attributes of existing measurement models. Theories and models are compared. The empirical analysis and discussion of the findings allows the researcher to identify six (06) dimensions and forty (40) attributes relevant to the measurement of corporate reputation in African banks. Reputational risk has been found critical for a bank to be successful and three (03) primary dimensions are of concern: Governance, Relationship with stakeholders and Regulatory compliance. A conceptual model has been proposed to measure and manage efficiently reputational risk.
Randomized Comparison of Bipolar versus Unipolar Plus Bipolar Recordings During Segmental Ostial Ablation of Pulmonary Veins

Unipolar vs Bipolar Electrograms. Introduction: Segmental ostial ablation to isolate pulmonary veins is guided by pulmonary vein potentials. The aim of this prospective randomized study was to compare the utility of unipolar plus bipolar electrograms versus only bipolar electrograms as a guide for segmental ablation to isolate the pulmonary veins in patients with atrial fibrillation.
Sharp Thresholds for Monotone Non-Boolean Functions and Social Choice Theory

A key fact in the theory of Boolean functions f: {0, 1}n → {0, 1} is that they often undergo sharp thresholds. For example, if the function f: {0, 1}n → {0, 1} is monotone and symmetric under a transitive action with Ep[f] = e and Eq[f] = 1−e, then q − p → 0 as n → ∞. Here Ep denotes the product probability measure on {0, 1}n where each coordinate takes the value 1 independently with probability p. The fact that symmetric functions undergo sharp thresholds is important in the study of random graphs and constraint satisfaction problems as well as in social choice. In this paper we prove sharp thresholds for monotone functions taking values in an arbitrary finite set. We also provide examples of applications of the results to social choice and to random graph problems. Among the applications is an analog for Condorcet’s Jury Theorem and an indeterminacy result for a large class of social choice functions.
Wireless monitoring of power quality disturbances in the supply to induction motor

The lifespan of electrical machines depends both on the type of operating load and on the nature of the supply on which it is operating. When there are unexpected aberrations occurring in the latter, it leads to Power Quality(PQ) disturbances. Among several PQ disturbances, voltage sag and swell are predominant in the case of inverter driven induction motors (IM). Hence condition monitoring (CM) of induction motor should also include the monitoring of the supply. Presently, CM of induction motors is done using traditional wired systems. This paper illustrates a methodology to wirelessly monitor voltage sag and swell in the supply to induction motor. Wireless monitoring is employed using ZigBee based Wireless Sensor Network (WSN). This WSN samples the stator current of the induction motor at a frequency of 1.8 KHz. Wavelet transform is applied for the stator current for feature extraction. Daubechies wavelet (db9) has emerged to be the most effective in the proposed work after several comparisons between different wavelets. These wavelet coefficients are fed as input to Artificial Neural Network (ANN) and k-Nearest Neighbour (kNN) classifiers for final classification. It is seen that ANN has a better classification accuracy of 92.5% as compared to kNN with a classification accuracy of 86.36%.
Prognostic Utility of Molecular Factors by Age at Diagnosis of Colorectal Cancer

Purpose: We hypothesized that adverse prognostic associations of specific tumor molecular factors vary by patient age at colorectal cancer diagnosis. Experimental Design: We examined the prognostic associations and interactions by age at colorectal cancer diagnosis (<60 vs. 60–74 vs. ≥75 years old) of key molecular factors—CpG island methylator phenotype (CIMP), microsatellite instability (MSI), KRAS, BRAF, and PIK3CA mutations, and nuclear CTNNB1 expression status—on colorectal cancer–specific survival (CSS) and overall survival (OS), using 1,280 incident colorectal cancer cases (median age, 69 years; range, 38–91 years) within the Nurses' Health Study and Health Professionals Follow-up Study cohorts. Results: MSI-high was associated with better survival, whereas BRAF mutation was associated with worse survival, but these associations did not appreciably differ by age group. Status of CIMP, KRAS mutation, or PIK3CA mutation was not associated with prognosis regardless of age. Nuclear CTNNB1 expression was associated with a trend toward worse prognosis among older adults [age ≥ 75 years; multivariate HR, 1.67; 95% confidence interval (CI), 0.89–3.13 (for CSS); multivariate HR, 1.44; 95% CI, 0.93–2.24 (for OS)] but not among younger patients, and there was a statistically significant interaction by age (Pinteraction = 0.03 for CSS; Pinteraction = 0.007 for OS). Conclusions: Tumor nuclear CTNNB1 expression may be associated with higher mortality among older patients with colorectal cancer but not among younger patients. Our findings need to be confirmed in independent datasets. Detailed exploration of tumor molecular signatures in older patients with colorectal cancer in large populations is warranted.

Simultaneous Wireless Information and Power Transfer: Technologies, Applications, and Research Challenges

Energy efficiency will play a crucial role in future communication systems and has become a main design target for all 5G radio access networks. The high operational costs and impossibility of replacing or recharging wireless device batteries in multiple scenarios, such as wireless medical sensors inside the human body, call for a new technology by which wireless devices can harvest energy from the environment via capturing ambient RF signals. SWIPT has emerged as a powerful means to address this issue. In this article, we survey the current architectures and enabling technologies for SWIPT and identify technical challenges to implement SWIPT. Following an overview of enabling technologies for SWIPT and SWIPT-assisted wireless systems, we showcase a novel SWIPT-supported power allocation mechanism for D2D communications to illustrate the importance of the application of SWIPT. As an ending note, we point out some future research directions to encourage and motivate more research efforts on SWIPT.
