The Empirical Content of Nash- Bargained Household Behavior

In households whose allocation decisions can be represented as Nash-bargained household decisions, extrahousehold environmental parameters (EEPs) serve as pure shifters of the threat points. The comparative statics of changes in demands due to changes in these EEPs are given. These are incorporated into a comprehensive statement of the empirical content of Nash-bargained household behavior, including a Nash generalization of Barten's (1966) fundamental matrix equation of the theory of consumer demand. Estimation and data requirements are discussed along with nested testing of the following structure: the neoclassical model is nested in the Nash-bargained model which, in turn, is nested in an unrestricted model of household demands. Emphasized throughout is the enriched menu of explanatory variables for demand analysis provided by the Nash model, as well as the model's ability to jointly analyze (i) household formation and (ii) intrahousehold allocation decisions.
Respiratory and cerebral circulatory control during exercise at .21 and 2.0 atmospheres inspired p02.

Respiratory and cerebral hemodynamic responses to leg exercise during respiration of air at 1.0 atm. and O2 at 2.0 atm. were studied in relation to changes in arterial and internal jugular venous blood oxygen composition, pH, pCO2 and bicarbonate concentration. The hyperpnea of exercise at 1.0 atm. was accompanied by arterial and venous acidemia and hypocapnia. Oxygen administration during exercise at 2.0 atm. lowered ventilation, restored arterial pH and pCO2 toward resting levels and caused venous pCO2 to rise above the resting level; cerebral venous cH remained elevated in spite of reduction of blood fixed acid concentration. The ventilatory response to exercise showed positive correlations with work load, oxygen consumption, and with changes in arterial and internal jugular venous cH and fixed acid. The observed negative correlations of changes in respiratory minute volume with changes in arterial and internal jugular venous pCO2 and bicarbonate concentration suggest that these factors are functions, rather than primary determinants, of ventilation in exercise. Cerebral hemodynamics and oxygen consumption were not significantly altered by exercise at 1.0 atm. The data suggest either a slight elevation of cerebral blood flow or reduction in the rate of cerebral oxygen consumption during exercise breathing O2 at 2.0 atm. , without gross elevation of cerebral venous pO2. Observed changes in cerebral vascular resistance during exercise at . 21 and 2.0 atm. inspired pO2 appear related to concomitant alterations in arterial pCO2, with no detectable relationship either to brain oxygen requirement of cerebral venous acid-base composition.

A Low-Profile Dual-Polarized Dipole Antenna Using Wideband AMC Reflector

A low-profile dual-polarized dipole antenna using wideband artificial magnetic conductor (AMC) reflector with stable radiation pattern for use in 2G/3G/4G base stations operating from 1.7 to 2.7 GHz is presented. The antenna consists of a pair of crossed-dipoles and a wideband AMC reflector which consists of an AMC surface, a metallic ground plane, and the air substrate between them. The AMC is designed to operate with 90° reflection-phase bandwidth of 1.64–2.88 GHz (54.8%). Compared with using perfect electric conductor reflector, the profile height of the dual-polarized dipole antenna using AMC reflector is reduced by half from 36 to 18 mm, resulting in the lowest-profile 2G/3G/4G base station antenna. Six metallic ground walls are used to stabilize the radiation pattern, and the resulted half-power beamwidths are around 68±3° and 81±3° in the H- and V-planes, respectively, across the operating band. More measured results show that wide impedance bandwidths of 1.67–2.98 and 1.64–3.05 GHz for the two input ports, isolation of more than 25 dB, and cross-polarization of less than −20 dB are achieved.
Prognostic implications of NPM1 mutations and FLT3 internal tandem duplications in Egyptian patients with cytogenetically normal acute myeloid leukemia

Abstract Nucleophosmin (NPM1) and fms-like tyrosine kinase 3-internal tandem duplication (FLT3-ITD) gene mutations represent the most frequent molecular aberrations in patients with cytogenetically normal-acute myeloid leukemia (CN-AML). We analyzed the prognostic impact of these mutations and their interactions in adults with CN-AML. NPM1 mutation (NPM1mut) and FLT3-ITD mutation (FLT3-ITD+) were analyzed by polymerase chain reaction and GeneScan assays of bone marrow samples obtained from newly diagnosed 104 CN-AML patients. FLT3-ITD+ and NPM1mut were detected in 36 (34.6%) and 30 (28.8%) out of 104 subjects, respectively, 16 cases (15.4%) had double NPM1mut/FLT3-ITD+. The incidence of FLT3-ITD+ was significantly higher in the NPM1mut group than in the NPM1 wild (NPM1wt) group (P = 0.018). Statistical analysis revealed that isolated NPM1mut group had a better clinical outcomes in terms of higher complete response (CR) rate (P = 0.01) and a trend towards favorable overall survival (OS) and disease-free survival (DFS) (P = 0.28, 0.40, respectively). In contrast, the isolated FLT3-ITD+ group had an unfavorable outcome in terms of lower CR rate (P = 0.12), shorter OS, and DFS (P < 0.0001 for both). The NPM1mut/FLT3-ITD-group had the best OS and DFS, while the NPM1wt/FLT3-ITD+ group had the worst OS and DFS than other groups (NPM1mut/FLT3-ITD+ or NPM1wt/FLT3-ITD−) (P < 0.0001 for both). Multivariate Cox regression analysis showed that age and FLT3/ITD+ were independent poor prognostic factors for OS (P = 0.006, <0.0001, respectively), while FLT3/ITD+ was independent predictor for DFS (P = 0.04). However, NPM1mut did not have a significant impact on OS and DFS. In conclusion, adult patients with CN-AML carrying isolated NPM1mut and isolated FLT3-ITD+ exhibit different clinical outcomes than those with NPM1mut/FLT3-ITD+ or NPM1wt/FLT3-ITD−. Patients with NPM1mut/FLT3-ITD− had the best prognosis in terms of higher CR, OS, and DFS, while those with NPM1mut/FLT3-ITD+ had the worst CR rate, and NPM1wt/FLT3-ITD+ had the lowest OS and DFS.
Posture Control—Human-Inspired Approaches for Humanoid Robot Benchmarking: Conceptualizing Tests, Protocols and Analyses

Posture control is indispensable for both humans and humanoid robots, which becomes especially evident when performing sensorimotor tasks such as moving on compliant terrain or interacting with the environment. Posture control is therefore targeted in recent proposals of robot benchmarking in order to advance their development. This Methods article suggests corresponding robot tests of standing balance, drawing inspirations from the human sensorimotor system and presenting examples from robot experiments. To account for a considerable technical and algorithmic diversity among robots, we focus in our tests on basic posture control mechanisms, which provide humans with an impressive postural versatility and robustness. Specifically, we focus on the mechanically challenging balancing of the whole body above the feet in the sagittal plane around the ankle joints in concert with the upper body balancing around the hip joints. The suggested tests target three key issues of human balancing, which appear equally relevant for humanoid bipeds: (1) four basic physical disturbances (support surface (SS) tilt and translation, field and contact forces) may affect the balancing in any given degree of freedom (DoF). Targeting these disturbances allows us to abstract from the manifold of possible behavioral tasks. (2) Posture control interacts in a conflict-free way with the control of voluntary movements for undisturbed movement execution, both with “reactive” balancing of external disturbances and “proactive” balancing of self-produced disturbances from the voluntary movements. Our proposals therefore target both types of disturbances and their superposition. (3) Relevant for both versatility and robustness of the control, linkages between the posture control mechanisms across DoFs provide their functional cooperation and coordination at will and on functional demands. The suggested tests therefore include ankle-hip coordination. Suggested benchmarking criteria build on the evoked sway magnitude, normalized to robot weight and Center of mass (COM) height, in relation to reference ranges that remain to be established. The references may include human likeness features. The proposed benchmarking concept may in principle also be applied to wearable robots, where a human user may command movements, but may not be aware of the additionally required postural control, which then needs to be implemented into the robot.
AN ASSESSMENT OF PORTUGUESE BANKS' COSTS AND EFFICIENCY

Banks play a central role in the fi nancial system and also in the real economy as the 2008 fi nancial crisis has vividly illustrated. Their smooth functioning allows for the intermediation of funds in the economy and provides for a wide range of fi nancial services. In order to ensure this banks need not only to adequately monitor their risks but also to effi ciently allocate their resources. Hence, the measurement of bank performance is a critical issue that has deserved considerable attention in the banking literature. In this paper, we propose to analyse developments in the performance of the Portuguese banking system between 1992 and 2004, a period in which signifi cant changes were observed, including the process of liberalization, consolidation and fi nancial innovation. 1 These changes had a profound impact on the market’s structure and on banks’ technology and, through the analysis of a cost function, we assess how they affected banks’ marginal costs and total productivity, which we decompose into the effect of scale effi ciency change, cost effi ciency change and technological progress. 2
Scalable Semantic Querying of Text

We present the KOKO system that takes declarative information extraction to a new level by incorporating advances in natural language processing techniques in its extraction language. KOKO is novel in that its extraction language simultaneously supports conditions on the surface of the text and on the structure of the dependency parse tree of sentences, thereby allowing for more refined extractions. KOKO also supports conditions that are forgiving to linguistic variation of expressing concepts and allows to aggregate evidence from the entire document in order to filter extractions. To scale up, KOKO exploits a multi-indexing scheme and heuristics for efficient extractions. We extensively evaluate KOKO over publicly available text corpora. We show that KOKO indices take up the smallest amount of space, are notably faster and more effective than a number of prior indexing schemes. Finally, we demonstrate KOKO's scale up on a corpus of 5 million Wikipedia articles.
Attitudes towards the use of GMOs in food production and their impact on buying intention: The role of positive sensory experience

European consumers are skeptical towards genetically modified organisms (GMOs) in food production, and their willingness to buy such products is low. Previous research also shows that these attitudes are quite resistant to attempts to change them by giving additional information. The aim of the study was to investigate if positive sensory experience with a (purportedly) GMO-based food product would influence consumers' attitude towards the use of GMOs in food production. An experiment was conducted in which subjects in the experimental group tasted cheeses, one of which was labeled as “produced using GMOs. ” The cheeses were selected in a way that ensured that the subject had a sensory preference for the GMO cheese. A control group tasted cheeses that were unlabelled. After the tasting, subjects completed a conjoint analysis task about cheese, in which the type of starter culture used (GMO|conventional) was one of the attributes. Subjects also were administered a set of items measuring attitude towards the use of GMOs in food production. Results showed that for subjects in the experimental group (who believed that they had tasted a GMO cheese, with which they had a positive sensory experience) (1) attitude towards GMO in food production was less negative, and (2) type of starter culture used (GM|conventional) had less impact on their buying intentions with regard to cheese than for subjects in the control group. lEconLit citations: L660, M310, Q130r. © 2004 Wiley Periodicals, Inc.

Death and injury from landmines and unexploded ordnance in Afghanistan.

CONTEXT Afghanistan is one of the countries most affected by injuries due to landmines and unexploded ordnance. OBJECTIVE To understand the epidemiological patterns and risk factors for injury due to landmines and unexploded ordnance. DESIGN AND SETTING Analysis of surveillance data on landmine and unexploded ordnance injuries in Afghanistan collected by the International Committee of the Red Cross in 390 health facilities in Afghanistan. Surveillance data were used to describe injury trends, injury types, demographics, and risk behaviors of those injured and explosive types related to landmine and unexploded ordnance incidents. PARTICIPANTS A total of 1636 individuals injured by landmines and unexploded ordnance, March 2001 through June 2002. RESULTS Eighty-one percent of those injured were civilians, 91.6% were men and boys, and 45.9% were younger than 16 years. Children were more likely to be injured by unexploded ordnance (which includes grenades, bombs, mortar shells, and cluster munitions), whereas adults were injured mostly by landmines. The most common risk behaviors for children were playing and tending animals; for adults, these risk behaviors were military activity and activities of economic necessity (eg, farming, traveling). The case-fatality rate of 9.4% is probably underestimated because surveillance predominantly detects those who survive long enough to receive medical care. CONCLUSIONS Landmine risk education should focus on hazards due to unexploded ordnance for children and on landmine hazards for adults and should address age-specific risk behaviors. Expanding community-based and clinic-based reporting will improve the sensitivity and representativeness of surveillance.
Contribution of hCAP-D2, a Non-SMC Subunit of Condensin I, to Chromosome and Chromosomal Protein Dynamics during Mitosis

ABSTRACT Condensins are heteropentameric complexes that were first identified as structural components of mitotic chromosomes. They are composed of two SMC (structural maintenance of chromosomes) and three non-SMC subunits. Condensins play a role in the resolution and segregation of sister chromatids during mitosis, as well as in some aspects of mitotic chromosome assembly. Two distinct condensin complexes, condensin I and condensin II, which differ only in their non-SMC subunits, exist. Here, we used an RNA interference approach to deplete hCAP-D2, a non-SMC subunit of condensin I, in HeLa cells. We found that the association of hCAP-H, another non-SMC subunit of condensin I, with mitotic chromosomes depends on the presence of hCAP-D2. Moreover, chromatid axes, as defined by topoisomerase II and hCAP-E localization, are disorganized in the absence of hCAP-D2, and the resolution and segregation of sister chromatids are impaired. In addition, hCAP-D2 depletion affects chromosome alignment in metaphase and delays entry into anaphase. This suggests that condensin I is involved in the correct attachment between chromosome kinetochores and microtubules of the mitotic spindle. These results are discussed relative to the effects of depleting both condensin complexes.
The role of HR managers in international mergers and acquisitions: a multiple case study

In recent years human resource (HR) managers have been encouraged to play a more strategic role in their organizations, especially in the case of extensive organizational change processes such as international mergers and acquisitions (IM&As). Today this requirement is even more acute since the past decade has been characterized by enormous growth in IM&As. In addition, it has been argued that the challenge in making M&As work is the management of people. In a case of IM&As the role of HR managers is very demanding because they needs to integrate HR practices and, moreover, perform two other roles simultaneously: a strategic role for company-wide integration and a support role for business unit transaction. Considering the importance of human resource management (HRM) in IM&As, it is surprising how little is known about the role and activities of HR managers in these processes. This study addresses the existing research gap by investigating the role of HR managers in the IM&A process. Based on semi-structured theme interviews among corporate level managers in three Finnish international industrial organizations, the roles of corporate HR managers at different stages of the IM&A process are analysed. This study applies Ulrich's (1997) theory of the four HR roles in combination with the HR issues which are present at the different stages of the IM&A process. This paper demonstrates that HRM is an essential part of M&As and that HR issues are given a lot of emphasis throughout the process. In addition, HR managers play an important role in the IM&A process, although it is not self-evident in every case.
Access to Financing in a Small Island Economy: Evidence From Mauritius

This relationship between access to financing and firm characteristics was studied. The authors used data from a survey of small and medium-sized enterprises from Mauritius, an island economy that is part of the sub-Saharan African continent. They examined the factors that affect the ability of firms to gain access to financing. Using the principal component analysis, the authors group variables affecting access to financing in four main components including working capital constraint, the external constraint, the size constraint, and the age constraint. The authors show that these components are important factors that influence the ability of firms to gain access to financing.
Acute Neuromuscular and Hormonal Responses to Resistance Exercise Using Variable External Resistance Loading

Variable resistance training (VRT) such as that employed by equipment that utilizes asymmetrical cams or pulleys (ASYM CAM) (e.g., Nautilus Machines) and elastic resistance (ELASTIC) are commonly used by athletes and fitness enthusiasts. However, the use of ELASTIC in high intensity training protocols has been controversial due to the limitation of providing a relatively low external force. The purpose of this study was designed to quantify and compare the acute responses in electromyogram signals (EMG) and the concentration of serum growth hormone ([GH]), testosterone ([T]), and lactate ([LA]) following fatiguing knee extension exercise with ELASTIC and ASYM CAM. In a counterbalanced cross-over study, nine male (21.08 ± 6.2 yrs) recreationally active subjects completed 5 sets of 10-RM knee extension exercise with ELASTIC and ASYM CAM with 3 wks of no training between experimental conditions. Blood sampling, maximum voluntary contraction (MVC) and EMG were recorded before, immediately, 15, 30, and 60 min after the termination of the exercise bout. The average of applied forces with ASYM CAM was significantly higher than ELASTIC (362 ± 34.2 N vs. 266.73 ± 58.56 N; P = .00) across the 5 sets of dynamic exercises. However, the average force and mean amplitude of MVC as well as the [GH], [T] and [LA] demonstrated no significant difference between the two types of exercise either in the pretest or during the recovery period (all P>0.05). Contrary to the traditional approach of using ELASTIC, which is for early rehabilitation purposes, the findings of the present study suggest ELASTIC is an acceptable exercise device for high intensity resistance training in the final stages of rehabilitation as well as athletic conditioning.
Generalized Random Gilbert-Varshamov Codes

We introduce a random coding technique for transmission over discrete memoryless channels, reminiscent of the basic construction attaining the Gilbert–Varshamov bound for codes in Hamming spaces. The code construction is based on drawing codewords recursively from a fixed type class, in such a way that a newly generated codeword must be at a certain minimum distance from all previously chosen codewords, according to some generic distance function. We derive an achievable error exponent for this construction and prove its tightness with respect to the ensemble average. We show that the exponent recovers the Csiszár and Körner exponent as a special case, which is known to be at least as high as both the random-coding and expurgated exponents, and we establish the optimality of certain choices of the distance function. In addition, for additive distances and decoding metrics, we present an equivalent dual expression, along with a generalization to infinite alphabets via cost-constrained random coding.
Reduction of Postoperative Ileus by Early Enteral Nutrition in Patients Undergoing Major Rectal Surgery: Prospective, Randomized, Controlled Trial

Background:The current trend in postoperative nutrition is to promote a normal oral diet as early as possible. However, postoperative ileus is a frequent and common problem after major abdominal surgery. This study was designed to investigate whether early enteral nutrition (EEN), as a bridge to a normal diet, can reduce postoperative ileus. Methods:Patients undergoing major rectal surgery for locally advanced primary or recurrent rectal carcinoma (after neoadjuvant (chemo)-radiation, with or without intraoperative radiotherapy) were randomly assigned to EEN (n = 61) or early parenteral nutrition (EPN, n = 62) in addition to an oral diet. Early nutrition was started 8 hours after surgery. Early parenteral nutrition was given as control nutrition to obtain caloric equivalence and minimize confounding. The primary endpoint was time to first defecation; secondary outcomes were morbidity, other ileus symptoms, and length of hospital stay. Results:Baseline characteristics were similar for both groups. In intention-to-treat analysis, the time to first defecation was significantly shorter in the enteral nutrition arm than in the control arm (P = 0.04). Moreover, anastomotic leakage occurred significantly less frequently in the enteral group (1 patient) compared with parenteral supplementation (9 patients, P = 0.009). Mean length of stay in the enteral group was 13.4 ± 2.2 days versus 16.7 ± 2.3 days in the parenteral group (P = 0.007). Conclusions:Early enteral nutrition is safe and associated with significantly less ileus. Early enteral nutrition is associated with less anastomotic leakage in patients undergoing extensive rectal surgery.
Group conflict handling: effects on group conflict type-group outcome relationships

OF THE THESIS GROUP CONFLICT HANDLING: EFFECTS ON GROUP CONFLICT TYPE-GROUP OUTCOME RELATIONSHIPS by Leslie A. DeChurch Florida International University, 2000 Miami, Florida Professor Michelle A. Marks, Major Professor Intragroup conflict research has shown task and relationship conflict have different effects on group outcomes, and suggests groups promote task conflict while avoiding relationship conflict. However, these suggestions have not yet been tested. This study examines the moderating role of group conflict handling on conflict type-group outcome relationships. Results of a field survey of 96 business school project groups showed task conflict inhibited performance when groups used avoidance tactics; however, these effects were negated when avoidance tactics were not used. Similarly, relationship conflict was only harmful to performance when avoided. When the use of avoidance was low, relationship conflict improved performance. Collaboration mitigated the harmful effects of task conflict and compromising mitigated those of relationship conflict on group satisfaction. Results from this work provide an important first look at how group conflict handling behaviors moderate the relationships between conflict types and group outcomes.
