Customer Satisfaction in Inbound Call Centers: A Study on the Role of Responsiveness and Assurance in Perceived Service Quality
The aim of this study is to analyze customer satisfaction in Inbound Call Centers and examine the relationship between Responsiveness and Assurance in Perceived Service Quality. The researchers proposed to study theoretical foundations on customer satisfaction and service quality dimensions adopting SERVQUAL Model to investigative the impact of service quality dimensions on customer satisfaction to meet the research objective. The association between perceived service quality and customer satisfaction will assist call center management to clarify the role of service quality dimensions in perceived service quality through customer point of view. The respondents for this study are the customers who receive service from call center of Telecommunication service providers in Visakhapatnam, Andhra Pradesh, India.
This research tested the effect of service quality dimensions on customer satisfaction and reported that both dimensions (responsiveness and assurance) had positive impact on customer satisfaction. Research results explore that Assurance has more impact on customer satisfaction than Responsiveness
Constitutive Overexpression of Muscarinic Receptors Leads to Vagal Hyperreactivity
BACKGROUND: Alterations in muscarinic receptor expression and acetylcholinesterase (AchE) activity have been observed in tissues from Sudden Infant Death Syndrome (SIDS). Vagal overactivity has been proposed as a possible cause of SIDS as well as of vasovagal syncopes. The aim of the present study was to seek whether muscarinic receptor overexpression may be the underlying mechanism of vagal hyperreactivity. Rabbits with marked vagal pauses following injection of phenylephrine were selected and crossed to obtain a vagal hyperreactive strain. The density of cardiac muscarinic receptors and acetylcholinesterase (AchE) gene expression were assessed. Blood markers of the observed cardiac abnormalities were also sought. METHODOLOGY/PRINCIPAL FINDINGS: Cardiac muscarinic M(2) and M(3) receptors were overexpressed in hyperreactive rabbits compared to control animals (2.3-fold and 2.5-fold, respectively) and the severity of the phenylephrine-induced bradycardia was correlated with their densities. A similar overexpression of M(2) receptors was observed in peripheral mononuclear white blood cells, suggesting that cardiac M(2) receptor expression can be inferred with high confidence from measurements in blood cells. Sequencing of the coding fragment of the M(2) receptor gene revealed a single nucleotide mutation in 83% of hyperreactive animals, possibly contributing for the transcript overexpression. Significant increases in AchE expression and activity were also assessed (AchE mRNA amplification ratio of 3.6 versus normal rabbits). This phenomenon might represent a compensatory consequence of muscarinic receptors overexpression. Alterations in M(2) receptor and AchE expression occurred between the 5th and the 7th week of age, a critical period also characterized by a higher mortality rate of hyperreactive rabbits (52% in H rabbits versus 13% in normal rabbits) and preceeded the appearance of functional disorders. CONCLUSIONS/SIGNIFICANCE: The results suggest that cardiac muscarinic receptor overexpression plays a critical role in the development of vagal hyperreactivity, whereas AchE hyperactivity appears as a compensatory consequence of it. Since similar vagal disorders were observed recently by us in SIDS, muscarinic receptor overexpression could become a marker of risk of vasovagal syncopes and SIDS
Serum levels of selenium and smoking habits at age 50 influence long term prostate cancer risk; a 34 year ULSAM follow-up
Background: Serum selenium level (s-Se) has been associated with prostate cancer (PrCa) risk. We investigated the relation between s-Se, smoking and non-screening detected PrCa and explored if polymorphisms in two DNA repair genes: OGG1 and MnSOD, influenced any effect of s-Se. Methods: ULSAM, a population based Swedish male cohort (n = 2322) investigated at age 50 for s-Se and s-Se influencing factors: serum cholesterol, erythrocyte sedimentation rate and smoking habits. At age 71 a subcohort, (n = 1005) was genotyped for OGG1 and MnSOD polymorphisms. Results: In a 34-year-follow-up, national registries identified 208 PrCa cases further confirmed in medical records. Participants with s-Se in the upper tertile had a non-significantly lower risk of PrCa. Smokers with s-Se in the two lower tertiles (<= 80 mu g/L) experienced a higher cumulative incidence of PrCa than smokers in the high selenium tertile (Hazard Ratio 2.39; 95% CI: 1.09-5.25). A high tertile selenium level in combination with non-wt rs125701 of the OGG1 gene in combination with smoking status or rs4880 related variation of MnSOD gene appeared to protect from PrCa. Conclusions: S-Se levels and smoking habits influence long-term risk of PrCa. Smoking as a risk factor for PrCa in men with low s-Se is relevant to explore further. Exploratory analyses of variations in OGG1 and MnSOD genes indicate that hypotheses about patterns of exposure to selenium and smoking combined with data on genetic variation in genes involved in DNA repair can be valuable to pursue
Evidence-based Kernels: Fundamental Units of Behavioral Influence
This paper describes evidence-based kernels, fundamental units of behavioral influence that appear to underlie effective prevention and treatment for children, adults, and families. A kernel is a behaviorāinfluence procedure shown through experimental analysis to affect a specific behavior and that is indivisible in the sense that removing any of its components would render it inert. Existing evidence shows that a variety of kernels can influence behavior in context, and some evidence suggests that frequent use or sufficient use of some kernels may produce longer lasting behavioral shifts. The analysis of kernels could contribute to an empirically based theory of behavioral influence, augment existing prevention or treatment efforts, facilitate the dissemination of effective prevention and treatment practices, clarify the active ingredients in existing interventions, and contribute to efficiently developing interventions that are more effective. Kernels involve one or more of the following mechanisms of behavior influence: reinforcement, altering antecedents, changing verbal relational responding, or changing physiological states directly. The paper describes 52 of these kernels, and details practical, theoretical, and research implications, including calling for a national database of kernels that influence human behavior

Combined spinal and epidural anesthesia with low doses of intrathecal bupivacaine in women with severe preeclampsia: A preliminary report
Background and Objectives: The purpose of our study was to evaluate the quality of anesthesia for cesarean delivery (CD), analgesia for labor (LA), hemodynamic changes, and neonatal effects of combined spinal and epidural anesthesia (CSE) with low intrathecal doses of bupivacaine and fentanyl in patients with severe preeclampsia.
Methods: Of the 85 patients with severe preeclampsia (systolic pressures [SBP] ā„160 mm Hg or diastolic pressures [DBP] ā„110 mm Hg, and proteinuria ā„100 mg/dL), 46 underwent CD and 39 delivered vaginally. The CD group received 7.5 mg of hyperbaric bupivacaine and 25 Ī¼g fentanyl intrathecally with a goal of obtaining a T4 sensory block. Those with levels less than T4 received 2% lidocaine epidurally to extend the block. In the LA group, the intrathecal dose was 1.25 mg of plain bupivacaine with 25 Ī¼g of fentanyl, followed by epidural infusion of 0.0625% to 0.125% bupivacaine with 2 to 4 Ī¼g fentanyl/mL at 12 to 15 mL/h.
Results: In the CD group, all but 4 patients had ā„T4 block, and these 4 patients received 2% lidocaine epidurally. None required conversion to general anesthesia. In the LA group, sensory levels were T10 (range, T6-L2) with adequate analgesia. The baseline mean arterial pressure (MAP) was 122 Ā± 13 mm Hg in the CD group and 117 Ā± 12 mm Hg in the LA group. After CSE, MAP decreased significantly and reached a nadir within 5 minutes in both groups (103 Ā± 12 mm Hg in the CD group and 96 Ā± 13 mm Hg in the LA group,
P < .05). The maximum decrease in MAP was similar in the 2 groups (ā15% Ā± 8% in the CD group and ā16% Ā± 9% in the LA group). The neonatal Apgar scores and umbilical artery (UA) pH were similar, and there were no significant correlations between UA pH and lowest MAP before delivery or the maximum percentage change in MAP in either group.
Conclusions: The results indicate that CSE with low intrathecal doses of bupivacaine and epidural supplementation, when needed, produces adequate anesthesia for CD and analgesia for labor in patients with severe preeclampsia. The maximum decreases in MAP after CSE were modest and quite similar in the 2 groups.

Schizophrenia, tardive dyskinesia and essential fatty acids
Several reports have indicated that people suffering from schizophrenia show an associated abnormality in levels of certain essential fatty acids (EFAs) in blood cells. Similar abnormalities have also been noted in association with the presence of tardive dyskinesia (TD). In order to study this further, 72 patients with the diagnosis of schizophrenia or schizoaffective disorder were examined to assess the relationship between psychiatric status, movement disorder (TD) and relative levels of the n-3 and n-6 essential fatty acids in red blood cell membranes and plasma. Patients were followed up over the next 4.5 years to determine whether or not changes in clinical state showed any systematic relationship to changes in essential fatty acid levels. We hypothesised that patients with schizophrenia would show persistently lowered levels of n-6 and n-3 series essential fatty acids, compared with normal controls. We further hypothesised that this abnormality would be greater in the presence versus absence of TD and the dominance of negative rather than positive symptoms. The only consistent findings were that lower levels of linoleic acid and higher levels of dihomogamma-linolenic acid characterised the patient population compared with control subjects but there was considerable variability in patients' EFA profile.Krishna S.
