Open and closed industry clusters: the social structure of innovation

In this paper we discuss knowledge and innovation in clusters and the benefits of clustering from a knowledge-based perspective. Knowledge-based resources and innovations are important sources of competitive advantage for firms. Aware of the importance of continuously seeking new knowledge firms increasingly seek knowledge-rich locations such as specific industry clusters across the world. These are locations characterized by the concentration of firms operating in related and supporting activities, a specialized work force and a specialized institutional environment that nurtures the industry. However, it is not likely that these clusters are always locations from which the firms will be able to draw the intended knowledge benefits. The social structure of the relationships between individuals and firms determines the extent to which knowledge will be created, will flow between co-located firms and bounds the knowledge benefits the firms may capture. We finish with a discussion of the need of further examination of the network dynamics involved in an industry cluster to obtain a clearer identification of the actual positive externalities that may accrue to co-locating firms.
Understanding atrial fibrillation, disease progression, management options, and patient-clinician communication

Atrial fibrillation (AF) is the most common cardiac arrhythmia. The progressive and chronic nature of this disease leads to heavy utilization of health care resources, with total health care expenditures estimated to be five times greater for patients with AF compared with those without AF. The management of AF involves thromboembolism prophylaxis, prevention of deterioration of cardiac function, and symptom control. As with other chronic disease states, an essential part of clinical care in AF is increasing a patient's understanding of the pathophysiology of AF, the consequences of untreated AF, and the therapeutic goals and potential side effects of treatment plans. Adherence to treatment regimens has the potential to have a large impact on patient outcomes. A reduction in symptoms along with a decrease in stroke incidence and morbidity may be the result of improved medication adherence. Health care professional communication of the management of AF and the treatment plan to an indi- vidual patient is multifaceted and essential to improving patient understanding, adherence to prescribed regimens, and clinical outcomes.
Evaluation of travel comfort of passengers – relationship between vehicle and environment

Abstract The aim of this paper is to present in more detail a part of the passengers’ travel comfort evaluation method in a rolling stocks design. This paper deals only with an interaction between a VEHICLE and an ENVIRONMENT. Introduced part of the method is focused on a mathematical model design of acting environmental factors on the vehicle and their random behaviour. The selected environmental factors are noise, vibrations, light and heat. Definition of sources of the selected factors are designed, their manners of a propagation in a surrounding (energetic path tracing) and statistical complex evaluation of final intensity of the selected factors in a random critical point of the vehicle interior as well. The mathematical model design is a simulation of the vehicles interior, which is possible to parametrically impact by geometrical and material indexes of the vehicle design.
PREDICTED IMPACTS OF PENSION REFORM ON THE LABOUR MARKET IN POLAND

Pension system reforms increasing retirement age and accentuating citizens’ individual responsibility for the amounts of their future pensions have effects on labour markets . This article provides an analysis of factors determining the interest of employees over 50, and even those over 45, in continued employment, as well as of relevant compulsion and risk factors. Some of the discussion deals with the assumptions underlying the Polish pension system reform and its likely effect on longer working lives. A hypothesis is formulated that for older employees to continue employment, working conditions must improve, as the responses of both older employees and their employers reveal insufficient sensitivity to the need to adapt the conditions to the capabilities of an ageing workforce. Yet, even if the necessary measures are taken, occupational stratification leading to the emergence of age-segmented labour market with low-skilled, precarious, and part-time jobs is unavoidable. The article is partly based on the results of a survey that a University of Łodź team conducted for the project Diagnosis of the current situation of women and men aged 50+ on the labour market in Poland , funded by the European Social Fund.
Inducible plasticity: optimal waiting time for the development of an inducible phenotype

Question: How does an organism that possesses inducible plasticity determine waiting time before the development of a secondary phenotype after changing to the secondary environment, in which the inducible secondary phenotype is suitable? Model: Maximization of the fitness currency, the survival possibility times the expected amount of remaining energy at terminal time, with respect to waiting time before development of a secondary phenotype. Key assumptions: If the individual develops the inducible secondary phenotype in the secondary environment, death rate is reduced. The development and maintenance of the inducible phenotype incurs a cost. Results: The optimal waiting time should be longer under the following conditions: when the inducible phenotype has low effectiveness in improving the survival rate of an organism exposed to the secondary environment; when the cost of development of the secondary phenotype is high; when the time delay required to develop the phenotype is short; or when the total energy that an organism possesses initially is low and fitness will be evaluated far in the future.
Measuring Individual Vulnerability

Standard poverty analysis makes statements about deprivation after the veil of uncertainty has been lifted. This implies that there is no meaningful role for risk as part of an assessment of potentially low states of well-being. In this paper, we introduce a concept of vulnerability, as a threat of poverty, with downside risk at its core. More specifically, we define a vulnerability measure as an assessment of the magnitude of the threat of poverty, measured ex-ante, before uncertainty is resolved. We describe the welfare-economic foundations for desirable properties of a vulnerability measure and assess to what extent some measures used in empirical work abide by them. We also present two families of measures that are fully consistent with our axiomatic approach.

Hepatoprotective effect of Ocimum basilicum extract against the toxicity of diazinon in albino rats: Histopathological and immunohistochemical evaluation

Recent studies showed that the Basil (Ocmuim basilicum) is known to have numerous pharmacological activities. The present study aims to investigate the efficacy of Ocmium basilicum extract, natural herb, against hepatotoxicity induced in rats by diazinon which is one of the most common insecticides. The intoxicated rats showed many pathological changes, including impairment of neutral structural organization of the hepatic lobule, leucocytic infiltration, cytoplasmic vacuolization of the hepatocytes and fatty degeneration. The immunohistochemical result showed increase cell proliferation as reflected by an increase in PCNA expression, whereas the increase in apoptotic rate was associated with an increase in the bax expression. Moreover the biochemical results showed that there was an increase in transaminases(AST, ALT). Concomitant treatment with aqueous extract of Basil led to an improvement in histological and immunohistochemical changes induced by diazinon and this attributed to basil antioxidant activity and free radicals scavenging properties.
Adult T cell leukemia aggressivenness correlates with loss of both 5-hydroxymethylcytosine and TET 2 expression

Mutations in TET2, encoding one of the TET members responsible for the conversion of DNA cytosine methylation to hydroxymethylation (5-hmc), have been recently described in Human T-lymphotropic virus type 1-associated adult T-cell leukemia/lymphoma (ATLL). However, neither the amount of genomic 5-hmc in ATLL tumor cells nor TET2 expression has been studied yet. In this study, we analyzed these two parameters as well as the mutational status of TET2 in ATLL patients. By employing a direct in situ approach, we documented that tumor T cells infiltrating lymph nodes exhibit low level of 5-hmc compared to residual normal T cells. Furthermore, this 5-hmc defect was more pronounced in tumor T cells from acute patients than from chronic ones and correlated with reduced expression of TET2 protein. TET2 variations were found in 14 patients (20%), including 13 with aggressive forms. Strikingly, 9 of the 14 patients showed the same variation (SNP rs72963007), whose frequency in ATLL patients was significantly higher than that of an ethnically matched control population (13% vs. 5%). However, no reduction of 5-hmc was found in PBMC from individuals possessing the variant rs72963007 TET2 allele, as compared to wild-type individuals. In contrast, a robust correlation was observed between 5-hmc and the levels of TET2 mRNA. Finally, loss of 5-hmc and TET2 downregulation both correlated with poor survival. These findings demonstrate that ATLL progression coincides with loss of genomic 5-hmc and indicate that downregulation of TET2, rather than TET2 mutations, is the key mechanism involved in 5-hmc modulation during ATLL progression.
Particularities of Oxidative Stress in Newborns

The oxidative stress at newborns is augmented by different conditions like preterm birth , asphyxia, respiratory distress, and intraventricular hemorrhage. Preterm neonates associ ate a more pronounced oxidative stress than healthy term newborns. Several neonatal conditions like respiratory distress (RDS), asphyxia, intraventricular hemorrhage, bron chopulmonary dysplasia, retinopathy, and necrotizing enterocolitis will increase the oxi - dative stress. The harmful effects of free radicals are linked to their capacity to react with polyunsaturated fatty acids of cell membranes, proteins, and nucleic acids. Free radicals will produce protein alteration with function loss and lipid peroxidation.
A Novel Broadband Printed Dipole Antenna and Its Application for TD-LTE Communications

Novel double-sided printed dipole antennas are proposed and investigated in this paper. Two pairs of identical T-shape metallic loadings are connected to the traditional double-sided printed dipole, enhancing the operating bandwidth. Simulations show that the proposed printed dipole without the reflecting ground plane gives a bandwidth of up to 90.7% for or 84.9% for , which is significantly greater than those of the traditional printed dipole. The proposed dipole is then applied to design a dual-polarized printed dipole antenna, mounted on a ground plane. Measurements for the prototype show a bandwidth of 68.8% for , covering the entire TD-LTE band. The gain is about 6–8 dBi and the isolation is over 24 dB over the bandwidth.
An Effective Pareto Optimality Based Fusion Technique for Information Retrieval

Information Retrieval (IR) is the process of retrieving information that is relevant to the users' needs. Over the years, researchers tend to develop the best retrieval strategy, which achieves the best possible performance across all document collections. Their results indicate a pattern of tug-of-war relationship prevalent among the existing strategies, where in one strategy dominates the remaining strategies over other document collections. Data Fusion may nullify the aforesaid tug-of-war effect. It can extract the best possible performance among the participating members. Data Fusion in IR usually combines the various retrieval schemes (strategies) to enhance the overall system performance. Our proposed fusion functions assign relevance scores by considering non dependency among all participating strategies. Relevance score assignment based on the relationship between that specific document and all other documents in the corpus. The existing Comb functions treated as the baseline functions for our proposed functions. Proposed and baseline functions' performance tested among three medium size corpuses. The average precision value of functions indicates that, one of our proposed functions achieves better performance in comparison with the base line functions. The statistical analysis confirms the same.
Types of Deception and Underlying Motivation

In computer-mediated communication, there are various types of possible deception such as category deception (gender switching), attractiveness deception, or identity concealment. The present article argues that it is meaningful to differentiate among these types of deception. More specifically, it is assumed that people attribute the various types of deception to different motivations and that these assumed motivations determine the evaluation of the deception. To examine whether individuals indeed attribute different types of deception to different underlying motivations, a scenario study was conducted. The results were in line with the expectations. For example, identity concealment was mainly attributed to privacy concerns, whereas gender switchingwas mainly perceived as playing with newroles and unknownaspects of the self. The assumed malicious intention predicted the evaluation of the deception.

Calcium Affects on Vascular Endpoints (CAVE) Retrospective Cohort Trial

Purpose The goal of this study was to examine the association of calcium supplements with coronary artery disease and survival. Our initial hypothesis was that when adjusted for risk factors, calcium supplements would not affect overall survival outcomes or coronary artery disease prevalence in a community population followed by a large cardiovascular practice. Methods Data was retrospectively collected for 5 years and 8 months (1/1/2004to 10/8/2009) from the electronic medical record at a large cardiovascular practice at a university. Only patients ≥ age 50 were included in our analysis Results The baseline characteristics of the 8060 study subjects. For the entire study population the mean age was 65 +/– 10 years, 71% were women. On multivariable logistic regression analysis, calcium supplementation was not an independent predictor of all-cause death, nor was calcium supplementation an independent predictor of the diagnosis of coronary artery disease. Survival analysis showed no survival differences for patients on calcium supplements (p = NS). Hazard ratios using the Cox proportional hazards model were calculated, showing that calcium supplementation was not an independent predictor of reduced survival. Conclusion This study suggests that there was no association between calcium supplementation and coronary artery disease as well as overall survival in a large retrospective cohort of patients greater than 50 with high rates of significant cardiovascular risk factors.
The Clinical Application of Therapeutic Neuroscience Education to Address Chronic Neck Pain Following a Whiplash Injury: A Case Report

Background: Chronic neck pain and functional disability is a common occurrence following whiplash injuries and frequently results in sensory, motor, and psychological dysfunction. Individuals presenting with chronic pain may exhibit widespread hypersensitivity, post-traumatic stress reactions, and emotional distress. Therapeutic neuroscience education (TNE) is a physical therapy intervention aiming to assist with pain, suffering, and disability by helping patients understand pain from a biological and physiological perspective. Case Description: The patient was a 42-year-old female presenting with left-sided neck pain with radiating symptoms throughout her left shoulder and spine following a motor vehicle accident. Evaluation at 7 months post-injury revealed intolerable pain throughout the cervical and thoracic spine, cervical mobility impairments, and a history of migraines, depression, and anxiety. This case report illustrates the rehabilitation approach used to enable effective execution of functional tasks in an unrestricted manner. Intervention: Rehabilitation progressed for 12 visits (6 weeks) including TNE, manual therapy, and therapeutic exercises. TNE was implemented to educate regarding nociceptive inputs, the sensory cortex, pain perception, central sensitization, and the brain neuromatrix. Outcome Measures: The patient demonstrated a Functional Measure of 31/100 and Physical Fear Score of 19/100 on the Focus On Therapeutic Outcomes (FOTO) Assessment during the initial evaluation. Following 6-weeks of physical therapy rehabilitation, the patient demonstrated a Functional Measure of 88/100 and Physical Fear Score of 80/100. Discussion: The purpose of this case report is to discuss the clinical reasoning and rehabilitation approach for an individual with chronic pain. This case report supports the use of TNE, manual therapy, and therapeutic exercise for chronic disorders in reducing pain, improving knowledge of pain, and reducing disability and psychosocial factors relating to pain.

The Physiological Responses to Dietary Administration of Zinc Bacitracin and Bacillus Mixture on Low-Weight Day-Old Chicks

This study investigated the responses of low-weight day-old chicks to zinc bacitracin and Bacillus mixture on growth performance, hematology, intestinal selected microbiota populations, and carcass characteristics. A total of 192 unsexed Lohman MB-202 day-old broiler chicks were randomly allotted to four dietary treatment groups of 48 chicks each (6 replicates of 8 chicks) and fed for 35 days. The four treatments were CONT (basal diet without supplementation), AGP (basal diet with 0.04% zinc bacitracin), PROB (basal diet supplemented with 0.5% Bacillus mixture), and PROB+AGP (basal diet supplemented with 0.5% Bacillus mixture and 0.04% zinc bacitracin). There were no significant differences in final body weight, feed intake, and feed conversion ratio of broilers. The relative weight of thymus was higher (P= 0.01) in AGP than that in PROB and PROB+AGP birds. Birds in PROB+AGP had lower (P= 0.04) values of alanine aminotransferase (ALT) enzyme compared to those in CONT and AGP groups, but the difference was not significant when compared with birds in PROB group. Serum creatinine was lower (P < 0.01) in PROB+AGP than in CONT and AGP birds. Birds in AGP group tended (P = 0.09) to have higher globulin concentration in the serum compared to other birds. There was also a tendency (P = 0.07) for PROB+AGP birds to have higher albumin to globulin ratio compared with other birds. There was more lactic acid bacteria in ileal digesta (P = 0.05) in PROB+AGP than in AGP birds, but the difference was not significant when compared to CONT and PROB birds. Birds in AGP group had higher (P = 0.05) relative breast weight compared to other birds. In conclusion, Bacillus mixture did not affect performance and hematological parameters, but increased the intestinal population of lactic acid bacteria in broiler chicks.
Using limitations of the auditory system to optimize hearing-aid design

Recent research has demonstrated that people with hearing impairment have limited ability to take advantage of temporal fine structure information (Strelcyk and Dau, 2009; Hopkins and Moore, 2011). This means that they will not be able to fully utilize auditory cues, such as interaural time differences and detailed pitch perception, which rely on such information. On the other hand, this reduced ability can also be used to improve on certain aspects of hearing-aid functionality. One such area is feedback suppression. Many of the latest hearing-aid introductions feature feedback suppression algorithms which apply a slight frequency shift to de-correlate the hearing-aid output from the input and thus minimize the risk of feedback. This paper will review evidence on temporal fine-structure abilities and relate this to how hearing-aid feedback systems can be designed to achieve a dual goal: to optimize the perceived sound quality of the listener with hearing impairment, whilst minimizing the occurrence of feedback.
