Does It Matter? an Hbr Debate 1 Introduction

he or she is an executive of uncommon intelligence and curiosity: the brightest CEO you know or can imagine, perhaps. We like to pretend that our ideal reader has chartered us to prepare a briefing every month. On the agenda, we've been told, should be three kinds of items. First, our reader says, bring me important new ideas, research, or insights: " Boss, here's something you should know. " Second, bring me important eternal truths, rediscovered and refreshed: " Boss, here's something you shouldn't forget. " Third, bring me into the picture about important issues and arguments: " Boss, here's something you will want to know about. " New ideas, truths, and disputes: When we do our job well, HBR is a forum where you get some of each, and all of it is important. Nicholas G. Carr's " IT Doesn't Matter, " published in the May 2003 issue, falls into the third category. It takes one side of an argument that's undeniably urgent and important to business leaders. In 2000, nearly half of U.S. corporate capital spending went to information technology. Then the spending collapsed and the Nasdaq with it, and in every boardroom–and in every technology company–people began to wonder: What happened? What was that spending about? What's changed? What has not? And what do we do now? What is our technology strategy, and how does it affect our corporate strategy? Forcefully, Carr argues that investments in IT, while profoundly important , are less and less likely to deliver a competitive edge to an individual company. " No one would dispute that information technology has become the backbone of commerce, " Carr says. " The point is, however, that the tech-nology's potential for differentiating one company from the pack – its strategic potential – inexorably diminishes as it becomes accessible and affordable to all. " Unsurprisingly, " IT Doesn't Matter " has generated an enormous amount of controversy. Our ideal reader wants that give-and-take, argument and counter-argument, the better to understand the issues. Always in such cases, people are more likely to write to us when they disagree with an article's point of view than when they agree with it. Always in such cases, a few people mistake the argument. (In this instance, the most common misperception is that the article says that IT is dead and that it will not continue to be a source of dramatic, …
Psycholinguistic variables involved in concept recall from the successive presentation of features / Variables psicolingüísticas involucradas en la evocación de conceptos a partir de la presentación de atributos sucesivos

Abstract The aim of this study was to analyse the psycholinguistic variables of the attributes and concepts involved in the recall of a concept. One hundred and twenty adults (18–40 years old) participated. A lexical recall task was administered by presenting a successive list of defining attributes. Forty concepts from different semantic categories were used. The attributes were obtained empirically from local Semantic Features Production Norms. The influence of the characteristics and attributes of the concepts on the number of participants who accessed the name of the concept and the correct guess trend was analysed. Significant values for Age of Acquisition, Presence of Distinctive Attributes and Presence of Taxonomic Attributes were observed. Results show that concepts which are acquired earliest are more easily recalled; presenting taxonomic categories narrows the search and the presence of distinctive attributes allow differentiating between such concepts within a category.
Multitasking and Persuasion: The Role of Structural Interference

Although the inhibiting effects of multitasking can be explained by 2 components, capacity interference (CI) and structural interference (SI), studies that have specifically focused on SI are limited. Thus, the present study examined the effects of SI in persuasion using 2 experimental studies. Results of Study 1 showed that SI (not CI) reduced both comprehension and counterarguing. In addition, results of Study 2 showed that SI effects occur not only in single-channel multitasking but also in dual-channel multitasking, and that SI effects occur not only when content interference is high (language-based multitasking) but also when it is low (non–language-based multitasking). The role of SI in multitasking effects has important implications for research on audience behaviors and persuasive communication.
Acute poststreptococcal glomerulonephritis with acute interstitial nephritis related to streptococcal pyrogenic exotoxin B

A 20-year-old man presented with symptoms of edema. Three weeks prior to admission, he experienced an upper respiratory tract infection. On admission, blood pressure was 177/118 mmHg. Initial laboratory investigations revealed serum creatinine, 170 µmol/L; complement C3, 130 mg/L and antistreptolysin O titer, 538 IU/mL (reference, <239 IU/mL). Urinalysis showed nephrotic range proteinuria and hematuria. A percutaneous kidney biopsy was performed. Light microscopy contained 20 glomeruli, 4 of which were globally sclerotic and 1 of which showed cellular crescent formation. Diffuse endocapillary proliferative glomerulonephritis was identified (Figure 1A). Forty percent of the interstitium was infiltrated by inflammatory cells (Figure 1B). Immunofluorescent staining revealed complement C3, mainly on capillary walls. Fig. 1. (A and B) Findings of the kidney biopsy. Hematoxylin and eosin-stained section showing diffuse endocapillary proliferation with massive infiltration of neutrophils (A) and inflammatory cells infiltration in the cortical interstitium (B). (C–F . Acute poststreptococcal glomerulonephritis (APSGN) with acute interstitial nephritis (AIN) was diagnosed. We administered methylprednisolone pulse therapy (1 g/day) for 3 days, followed by prednisolone at 80 mg/day. The serum creatinine level declined to 74 µmol/L and proteinuria decreased to <1 g/day. Transient type 4 renal tubular acidosis was observed during steroid treatment. AIN is found in the infectious diseases of children, particularly in streptococcal infection [1]. We investigated the localization of two streptococcal antigens, streptococcal pyrogenic exotoxin B (SPEB) and nephritis-associated plasmin receptor (NAPlr), using an anti-SPEB antibody (Abcam, Cambridge, MA) and a fluorescein isothiocyanate-conjugated anti-NAPlr antibody [1F10] (Abcam). Although NAPlr was not detected, SPEB was positive in the interstitium as well as glomeruli (Figure 1C–F). Chang et al. [2] reported a case of streptococcal infection-related AIN, in which SPEB was found in both tubular epithelial cells and interstitium. In the present case, negative results were obtained for SPEB in tubular epithelial cells. Similarly, SPEB and its precursors have been detected only in glomeruli and interstitium in the rat kidney [3]. SPEB has been reported in association with the pathogenesis of APSGN. The mechanisms of leukocyte infiltration could be mediated by chemotactic effects and the migration inhibitor factor-like activities of SPEB [3]. SPEB also induces proliferation of human mononuclear leukocytes [4]. SPEB may be one of the causes of streptococcal infection-related AIN.
MOP3, a component of the molecular clock, regulates the development of B cells

Differentiation and proliferation of haematopoietic progenitor cells occur in intimate contact with the bone marrow microenvironment which is composed of stromal cells and extracellular matrix proteins. MOP3 (also known as brain and muscle Arnt‐like protein‐1, BMAL1), a master regulator of circadian rhythm, plays important roles in the regulation of cell differentiation and general physical functions. In the present studies, MOP3‐deficient mice had significantly reduced levels of B cells in the peripheral blood, spleen and bone marrow compared MOP3+/– or MOP3+/+ littermates. Flow cytometry analysis showed the levels of pre‐B cells in bone marrow of MOP3–/– mice were similar as that in control mice. Adoptive transfer of MOP3–/– bone marrow cells (BMC) to lethally irradiated BALB/c Rag2–/– recipients, normal T and B cell development was observed, whereas Adoptive transfer of BALB/c BMC to lethally irradiated MOP3–/– recipients, B‐cell development was significantly impaired. These results presented herein with MOP3‐deficient mice reveal the involvement of MOP3 in the development of B cells, but not other immune cells. The effect of MOP3 on the differentiation of pre‐B cells to mature B cells might be mediated by the bone marrow microenvironment. This study also showed a connection between a master regular of circadian rhythm with B‐cell development in mice.
Relation of central hemodynamics to obesity and body fat distribution.

Central obesity increases the risk for cardiovascular disease, but little is known about its hemodynamic effects. The aims were to investigate the influence of obesity (as defined by body mass index) and abdominal fat accumulation (as defined by the waist/hip ratio) on hemodynamics at rest and during mental stress. Invasive hemodynamic studies were performed in 20 healthy, normotensive young men (aged 18-22 years) recruited from an unbiased population sample. Their body mass index and waist/hip ratio ranged between 18.5 and 30.2 (mean 24.1) and 0.77 and 0.98 (mean 0.87), respectively. Hemodynamics were related to the two anthropometric indexes by bivariate regression analyses. Cardiac output and stroke volume were positively correlated to body mass index (p = 0.05 and p = 0.005), but inversely to waist/hip ratio (p = 0.01 and p = 0.01). Mental stress augmented the hemodynamic patterns. Total peripheral resistance during stress correlated inversely to body mass index (p = 0.02), whereas high waist/hip ratio was associated with higher systemic vascular resistance p = 0.002). The delta CO/delta MAP ratio, i.e., relative contribution of cardiac output for the stress-induced increase in mean arterial pressure, showed a strong positive association with body mass index (p = 0.004), but was inversely related to the waist/hip ratio (p = 0.002). Serum insulin correlated significantly to the stress-induced change in total peripheral resistance (r = 0.54; p = 0.02), whereas the increase in cardiac output was inversely related to insulin (r = -0.59; p = 0.007). Thus, central obesity is associated with a specific hemodynamic pattern characterized by higher total peripheral resistance, lower cardiac output, and a vasoconstrictor response to psychosocial stress.
A conditional predictive p-value to compare a multinomial with an overdispersed multinomial in the analysis of T-cell populations

Immunological experiments that record primary molecular sequences of T-cell receptors produce moderate to high-dimensional categorical data, some of which may be subject to extra-multinomial variation caused by technical constraints of cell-based assays. Motivated by such experiments in melanoma research, we develop a statistical procedure for testing the equality of two discrete populations, where one population delivers multinomial data and the other is subject to a specific form of overdispersion. The procedure computes a conditional-predictive p-value by splitting the data set into two, obtaining a predictive distribution for one piece given the other, and using the observed predictive ordinate to generate a p-value. The procedure has a simple interpretation, requires fewer modeling assumptions than would be required of a fully Bayesian analysis, and has reasonable operating characteristics as evidenced empirically and by asymptotic analysis.
Stress Testing Credit Risk: A Survey of Authorities' Approaches

This paper reviews the quantitative methods used at selected central banks to stress testing credit risk, focusing in particular on the methods used to link macroeconomic drivers of stress with bank specific measures of credit risk (macro stress test). Stress testing credit risk is an essential element of the Basel II Framework; because of their financial stability perspective, central banks and supervisors are particularly interested in quantifying the macro-to-micro linkages and have developed a specific modeling expertise in this field. In assessing current macro stress testing practices, the paper highlights the more recent developments and a number of methodological challenges that may be useful for supervisors in their review process of the banks' stress test models as required by the Basel II Framework. It also contributes to the on-going macroprudential research efforts that aim to integrate macroeconomic oversight and prudential supervision, in the direction of early identification of key vulnerabilities and assessment of macro-financial linkages.

Cleavage of adenovirus type 2 DNA into six unique fragments by endonuclease R-RI.

The DNA of adenovirus type 2 was cleaved by restriction endonuclease R.RI into six fragments. These fragments were separated by electrophoresis on composite agarose-polyacrylamide gels. Their molecular weights ranged from 1.1 x 10(6) to 13.6 x 10(6), as measured by electron microscopy. Each fragment represented a unique segment of adenovirus type 2 DNA since: (i) the fragments were obtained in equimolar amounts; (ii) the sum of their molecular weights was equal to the molecular weight of complete adenovirus DNA; and (iii) each fragment exhibited a rate of renaturation that was inversely proportional to its size.
Continuous Time Extraction of a Nonstationary Signal with Illustrations in Continuous Low-Pass and Band-Pass Filtering

This paper sets out the theoretical foundations for continuous-time signal extraction in econometrics. Continuous-time modeling gives an effective strategy for treating stock and flow data, irregularly spaced data, and changing frequency of observation. We rigorously derive the optimal continuous-lag filter when the signal component is nonstationary, and provide several illustrations, including a new class of continuous-lag Butterworth filters for trend and cycle estimation.
Functioning in neck and low back pain from a 12-year perspective: a prospective population-based study.

OBJECTIVE The aim of this study was to evaluate the effects of unspecific neck pain and low back pain at a given time (1990-91) with respect to physical and social functioning and role limitations due to emotional problems 12 years later. METHODS A rural male study population (2351 individuals) was established in 1989 and a first survey conducted in 1990-91. A follow-up survey was performed in 2002-03. A total of 1405 persons participated in both surveys. Functioning and role limitations in 2002-03 were evaluated using the SF-36 instrument. Several possible confounders were included in the analyses. RESULTS Unspecific neck pain or low back pain in 1990-91 was shown in a multivariate longitudinal regression model to be significantly related to limited physical (odds ratio (OR)=2.08; 95% confidence interval (CI) 1.51-2.87) and social (OR=1.92; 95% CI 1.33-2.75) functioning 12 years later. The effects were only slightly modified by the confounders analysed. However, higher education independently and significantly predicted a low risk for functional limitations. CONCLUSION Non-specific neck pain and low back pain at a given time impacted on the risk of limited physical and social functioning many years later. Current symptoms of depression and anxiety at the time for the second survey had a high impact on functional limitations.
Occupational paternal exposure to benzene and risk of spontaneous abortion.

OBJECTIVE--The purpose of this study was to evaluate the risk of spontaneous abortion among the wives of male workers occupationally exposed to benzene. METHODS--The wives of 823 men working in two chemical plants at the time of the study were asked to complete a questionnaire describing their pregnancies. The analysis of the 1739 pregnancies that ended in a spontaneous abortion or a birth is presented. The firms' payroll records provided all workers' employment history, including dates. Benzene exposure, graded at two levels (< 5, > or = 5 ppm), was determined for every job, so that benzene exposure for each worker's entire professional life (at these companies) could be assessed. This information was linked to the dates of the pregnancies reported in the questionnaires to enable the exposure status of each pregnancy to be defined (1270 non-exposed and 274 exposed). The frequency of spontaneous abortion, defined as the number of spontaneous abortions divided by the total of spontaneous abortions and births was evaluated. RESULTS--When adjusted for tobacco consumption, mother's age and pregnancy order, the odds ratio of the association between paternal exposure to approximately 5 ppm of benzene and the risk of spontaneous abortion was close to and statistically not different from unity (OR = 1.1; 95% CI (0.7-1.8). CONCLUSION--In this study paternal exposure to benzene did not increase the risk of spontaneous abortion.
Cohomology in the pure spinor formalism for the superstring

A manifestly super-Poincare covariant formalism for the superstring has recently been constructed using a pure spinor variable. Unlike the covariant Green-Schwarz formalism, this new formalism is easily quantized with a BRST operator and tree-level scattering amplitudes have been evaluated in a manifestly covariant manner. In this paper, the cohomology of the BRST operator in the pure spinor formalism is shown to give the usual light-cone Green-Schwarz spectrum. Although the BRST operator does not directly involve the Virasoro constraint, this constraint emerges after expressing the pure spinor variable in terms of SO(8) variables.
Interactive Nonlinear Learning Environments.

E-learning materials often have a linear design where all learners are forced into a single-mode pedagogy, which is contrary to the interaction that occurs in face-to-face learning. Ideally, e-learning materials should be nonlinear, interactive, contain context-sensitive and active learning elements, and accommodate various learning levels and styles. This paper presents an educator’s perspective on approaches to designing such e-learning materials, which are essential to enhancing the education of future generations of students.
``Non chiral'' primary superfields in the AdS_{d+1}/CFT_d correspondence

We consider some long multiplets describing bulk massive excitations of M-theory two-branes and IIB string three-branes which correspond to ``non chiral'' primary operators of the boundary OSp(8/4) and SU(2,2/4) superconformal field theories. Examples of such multiplets are the ``radial'' modes on the branes, including up to spin 4 excitations, which may be then considered as prototypes of states which are not described by the K-K spectrum of the corresponding supergravity theories on AdS_4 x S_7 and AdS_5 x S_5 respectively.
Tunable Handset Antenna: Enhancing Efficiency on TV White Spaces

With the future long term evolution (LTE) auction for television white spaces at 600 MHz, there is a strong need for efficient handset antennas operating at very low frequencies. This communication shows a tunable antenna covering the LTE bands from 600 MHz to 2.6 GHz. The antenna uses state-of-the-art microelectromechanical system tunable capacitors in order to reconfigure its operating frequency. In this communication, the design mitigates the tuning loss with a tunable extended ground plane. The resulting dual-resonant antenna exhibits a peak total efficiency of −3.9 dB at 600 MHz.
Interest-Based Peer Selection in P2P Network

Currently most distributed peer-to-peer network systems send to other peers when users' query request, but their search result is a great deal of needless answer as gap between their search goal and their information need. It is because each peers own different interest domain knowledge. However, we purpose interest-based peer selection in order to rank best peers under the user context with content retrieval tasks. Generally speaking, providers may be best peers what user want find. Providers can satisfy users' information need, if we figure out providers what are user search goal. Based on ACM domain knowledge, we propose reference ontology in order to calculate the semantic similarity under each peer preferences, and rank best peers. Feedback data is updated ontological user profile by user activities and content retrieval tasks. Our approach can satisfy users' information need and reduce their search time-consuming.

A Study of Heart Disease Prediction in Data Mining

The data mining techniques can extract the hidden information from the large databases. It helps to find the relationships and patterns from the data. Data mining is used for various applications such as business organizations, e-commerce, health care industry, scientific and engineering. In the health care industry the data mining is mainly used for predicting the diseases from the datasets. In this survey paper, we have studied and analyzed how data mining techniques such as classification, clustering, fuzzy system and association rules are used for predicting the heart diseases. This paper also gives the advantages and disadvantages of the existing techniques. It also discusses the future enhancements of the existing works.
