Politics and Firm Boundaries: How Organizational Structure, Group Interests, and Resources Affect Outsourcing

How does managers' pursuit of their own intraorganizational interests affect decisions about what work to outsource and how to contract with vendors? I study this question using a qualitative study of outsourcing in the information technology department of a large financial services firm. Traditional transaction cost-based theories argue that decisions about which transactions to outsource should reflect the characteristics of those transactions, yet I find only a weak link between transaction characteristics and outsourcing decisions. Qualitative evidence suggests that managers' pursuit of their own intraorganizational interests helps to explain why outsourcing decisions were often divorced from transaction characteristics. I found that the consequences of outsourcing projects were consistent with the assumptions of transaction cost and capabilities-based theories: managers had less authority over outsourced projects than internal ones, those projects were subject to weaker administrative controls, and outsourced vendors provided different capabilities than internal suppliers. However, the way that those consequences were evaluated often reflected managers' own interests rather than those of the organization. I highlight three aspects of organizational structure that affected how managers evaluated outsourcing: the nature of differentiated goals and responsibilities, the administrative controls that managers faced, and the pressures caused by interdependent workflows within the organization. I also show how the distribution of authority and other resources shaped which projects were outsourced. The analysis highlights the value of understanding make-or-buy decisions as an endogenous consequence of the structure in which those decisions take place, rather than as isolated decisions that are maximized regardless of their context.
Gender differences in the management and clinical outcome of stable angina.

BACKGROUND
We sought to examine the impact of gender on the investigation and subsequent management of stable angina and to assess gender differences in clinical outcome at 1 year.


METHODS AND RESULTS
The Euro Heart Survey of Stable Angina enrolled patients with a clinical diagnosis of stable angina on initial assessment by a cardiologist. Baseline clinical details and cardiac investigations planned or performed within a 4-week period of the assessment were recorded, and follow-up data were collected at 1 year. A total of 3779 patients were included in the survey; 42% were female. Women were less likely to undergo an exercise ECG (odds ratio, 0.81; 95% CI, 0.69 to 0.95) and less likely to be referred for coronary angiography (odds ratio, 0.59; 95% CI, 0.48 to 0.72). Antiplatelet and statin therapies were used significantly less in women than in men, both at initial assessment and at 1 year, even in those in whom coronary disease had been confirmed. Women with confirmed coronary disease were less likely to be revascularized than their male counterparts and were twice as likely to suffer death or nonfatal myocardial infarction during the 1-year follow-up period (hazard ratio, 2.09; 95% CI, 1.13 to 3.85), even after multivariable adjustment for age, abnormal ventricular function, severity of coronary disease, and diabetes.


CONCLUSIONS
Significant gender bias has been identified in the use of investigations and evidence-based medical therapy in stable angina. Women were also less likely to be revascularized. The observed bias is of particular concern in light of the adverse prognosis observed among women with stable angina and confirmed coronary disease.
Using the EMFi chair to measure the user ’ s emotion-related heart rate responses

Jenni Anttonen: Using the EMFi chair to measure the user's emotion-related heart rate responses Master's thesis, 55 pages, 2 appendix pages May 2005 The research reported here is part of a multidisciplinary collaborative project that aimed at developing embedded measurement devices using electromechanical film (EMFi) as a basic measurement technology. The present aim was to test if an unobtrusive heart rate measurement device, the EMFi chair, had the potential to detect heart rate changes associated with emotional stimulation. Six-second long visual, auditory, and audiovisual stimuli with negative, neutral, and positive emotional content were presented to 24 participants. Heart rate responses were measured with the EMFi chair and with earlobe photoplethysmography (PPG). Also, subjective ratings of the stimuli were collected. Firstly, the high correlation between the measurement results of the EMFi chair and PPG, r = 0.99, p < 0.001, indicated that the EMFi chair measured heart rate reliably. Secondly, heart rate showed a decelerating response to visual, auditory, and audiovisual emotional stimulation. The emotional stimulation caused statistically significant changes in heart rate at the 6 th second from stimulus onset so that the responses to negative stimulation were significantly lower than the responses to positive stimulation. The results were in line with previous research. The results show that heart rate responses measured with the EMFi chair differed significantly for positive and negative emotional stimulation. These results suggest that the EMFi chair could be used in HCI to measure the user's emotional responses unobtrusively.
Learning agent models in SeSAm

Designing the agent model in a multiagent simulation is a challenging task due to the generative nature of such systems. In this contribution we present an extension to the multiagent simulation platform SeSAm, introducing a learning-based design strategy for building agent behavior models.
Defining a healthy human gut microbiome: current concepts, future directions, and clinical applications.

Indigenous microbiota are an essential component in the modern concept of human health, but the composition and functional characteristics of a healthy microbiome remain to be precisely defined. Patterns of microbial colonization associated with disease states have been documented, but the health-associated microbial patterns and their functional characteristics are less clear. A healthy microbiome, considered in the context of body habitat or body site, could be described in terms of ecologic stability (i.e., ability to resist community structure change under stress or to rapidly return to baseline following a stress-related change), by an idealized (presumably health-associated) composition or by a desirable functional profile (including metabolic and trophic provisions to the host). Elucidation of the properties of healthy microbiota would provide a target for dietary interventions and/or microbial modifications aimed at sustaining health in generally healthy populations and improving the health of individuals exhibiting disrupted microbiota and associated diseases.
Development of bio-based fine chemical production through synthetic bioengineering

Fine chemicals that are physiologically active, such as pharmaceuticals, cosmetics, nutritional supplements, flavoring agents as well as additives for foods, feed, and fertilizer are produced by enzymatically or through microbial fermentation. The identification of enzymes that catalyze the target reaction makes possible the enzymatic synthesis of the desired fine chemical. The genes encoding these enzymes are then introduced into suitable microbial hosts that are cultured with inexpensive, naturally abundant carbon sources, and other nutrients. Metabolic engineering create efficient microbial cell factories for producing chemicals at higher yields. Molecular genetic techniques are then used to optimize metabolic pathways of genetically and metabolically well-characterized hosts. Synthetic bioengineering represents a novel approach to employ a combination of computer simulation and metabolic analysis to design artificial metabolic pathways suitable for mass production of target chemicals in host strains. In the present review, we summarize recent studies on bio-based fine chemical production and assess the potential of synthetic bioengineering for further improving their productivity.
Relatives in the resuscitation room: their point of view.

OBJECTIVE
To investigate whether bereaved next of kin would like to have been present in the resuscitation room during attempted cardiopulmonary resuscitation of their relative, and their experience or knowledge of what is involved in cardiopulmonary resuscitation.


METHODS
The next of kin of patients who had recently died after unsuccessful cardiopulmonary resuscitation in the accident and emergency department were contacted initially by telephone and then sent a postal questionnaire.


RESULTS
Four (11%) of 35 respondents had been asked whether they wished to be present in the resuscitation room; 24 (69%) would like to have been offered the opportunity, even though not all would have accepted. The respondents had a wide variety of perceptions of what happens during resuscitation, few of which corresponded to clinical practice.


CONCLUSIONS
Most relatives of patients requiring cardiopulmonary resuscitation would like to be offered the possibility of being in the resuscitation room; this could have several benefits.
Institutional Investors and Stock Market Liquidity : Trends and Relationships

In this paper we show that institutional participation in the U.S. stock market in recent decades has played an ever increasing role in explaining cross-sectional variation in stock market illiquidity. We first document trends in the growth of institutional stock ownership using the 13F holdings, extending the evidence by thirteen years to the end of 2010. In contrast to previous research, we find that institutions, and particularly hedge funds, have increased their holdings of smaller stocks and decreased their holdings of larger stocks over this period. Institutions currently underweight the largest stocks and overweight the smallest stocks relative to market weights. We then examine the relation between illiquidity and two measures of institutional stock ownership – the percentage of a stock owned by institutions and the number of institutions that own the stock – both in the cross section and through time. We find that: (1) the number of institutions that own and trade a stock is more important than the percentage of institutional ownership in explaining the cross-sectional variability of illiquidity; and (2) the power of the number of institutional owners in explaining illiquidity is significantly stronger in the second half of our sample period.
Video Game Playing, Attention Problems, and Impulsiveness: Evidence of Bidirectional Causality

The present study examines video game playing as it relates to attention problems and impulsiveness in a sample of 3,034 children and adolescents from Singapore measured over 3 years. Consistent with previous research, those who spend more time playing video games subsequently have more attention problems, even when earlier attention problems, sex, age, race, and socioeconomic status are statistically controlled. Violent content may have a unique effect on attention problems and impulsiveness, but total time spent with video games appears to be a more consistent predictor. Individuals who are more impulsive or have more attention problems subsequently spend more time playing video games, even when initial video game playing is statistically controlled, suggesting bidirectional causality between video game playing and attention problems/ impulsiveness.
Ensemble dependence model for classification and prediction of cancer and normal gene expression data

MOTIVATION
DNA microarray technologies make it possible to simultaneously monitor thousands of genes' expression levels. A topic of great interest is to study the different expression profiles between microarray samples from cancer patients and normal subjects, by classifying them at gene expression levels. Currently, various clustering methods have been proposed in the literature to classify cancer and normal samples based on microarray data, and they are predominantly data-driven approaches. In this paper, we propose an alternative approach, a model-driven approach, which can reveal the relationship between the global gene expression profile and the subject's health status, and thus is promising in predicting the early development of cancer.


RESULTS
In this work, we propose an ensemble dependence model, aimed at exploring the group dependence relationship of gene clusters. Under the framework of hypothesis-testing, we employ genes' dependence relationship as a feature to model and classify cancer and normal samples. The proposed classification scheme is applied to several real cancer datasets, including cDNA, Affymetrix microarray and proteomic data. It is noted that the proposed method yields very promising performance. We further investigate the eigenvalue pattern of the proposed method, and we discover different patterns between cancer and normal samples. Moreover, the transition between cancer and normal patterns suggests that the eigenvalue pattern of the proposed models may have potential to predict the early stage of cancer development. In addition, we examine the effects of possible model mismatch on the proposed scheme.
The constructionist approach to framing: Bringing culture back in

This article aims, within the constructionist paradigm, at integrating culture into the framing process. Four characteristics are important for this approach: the distinction between the event, the media content, and the frame; the explicit attention to the reconstruction of frame packages; the relationship between frame packages and cultural phenomena; and the interaction between frame sponsors, key events, media content, schemata, and the stock of frames. An elaborated framing model is presented, and, subsequently, the constructionist approach is compared with priming and agenda setting. Finally, the methodological implications are discussed, in order to develop a strategy to reconstruct frame packages.

The second part describes the different game mechanisms and dynamics used in gamification and finally, a reflection is made about the impact gamification could have in participation.
Fast and Energy-Efficient CNN Inference on IoT Devices

Convolutional Neural Networks (CNNs) exhibit remarkable performance in various machine learning tasks. As sensor-equipped internet of things (IoT) devices permeate into every aspect of modern life, it is increasingly important to run CNN inference, a computationally intensive application, on resource constrained devices. We present a technique for fast and energy-efficient CNN inference on mobile SoC platforms, which are projected to be a major player in the IoT space. We propose techniques for efficient parallelization of CNN inference targeting mobile GPUs, and explore the underlying tradeoffs. Experiments with running Squeezenet on three different mobile devices confirm the effectiveness of our approach.

Prenatal tobacco smoke exposure increases hospitalizations for bronchiolitis in infants.

BACKGROUND
Tobacco smoke exposure (TSE) is a worldwide health problem and it is considered a risk factor for pregnant women's and children's health, particularly for respiratory morbidity during the first year of life. Few significant birth cohort studies on the effect of prenatal TSE via passive and active maternal smoking on the development of severe bronchiolitis in early childhood have been carried out worldwide.


METHODS
From November 2009 to December 2012, newborns born at ≥ 33 weeks of gestational age (wGA) were recruited in a longitudinal multi-center cohort study in Italy to investigate the effects of prenatal and postnatal TSE, among other risk factors, on bronchiolitis hospitalization and/or death during the first year of life.


RESULTS
Two thousand two hundred ten newborns enrolled at birth were followed-up during their first year of life. Of these, 120 (5.4%) were hospitalized for bronchiolitis. No enrolled infants died during the study period. Prenatal passive TSE and maternal active smoking of more than 15 cigarettes/daily are associated to a significant increase of the risk of offspring children hospitalization for bronchiolitis, with an adjHR of 3.5 (CI 1.5-8.1) and of 1.7 (CI 1.1-2.6) respectively.


CONCLUSIONS
These results confirm the detrimental effects of passive TSE and active heavy smoke during pregnancy for infants' respiratory health, since the exposure significantly increases the risk of hospitalization for bronchiolitis in the first year of life.
Manipulation of dietary short chain carbohydrates alters the pattern of gas production and genesis of symptoms in irritable bowel syndrome.

BACKGROUND AND AIM
Reduction of short-chain poorly absorbed carbohydrates (FODMAPs) in the diet reduces symptoms of irritable bowel syndrome (IBS). In the present study, we aimed to compare the patterns of breath hydrogen and methane and symptoms produced in response to diets that differed only in FODMAP content.


METHODS
Fifteen healthy subjects and 15 with IBS (Rome III criteria) undertook a single-blind, crossover intervention trial involving consuming provided diets that were either low (9 g/day) or high (50 g/day) in FODMAPs for 2 days. Food and gastrointestinal symptom diaries were kept and breath samples collected hourly over 14 h on day 2 of each diet.


RESULTS
Higher levels of breath hydrogen were produced over the entire day with the high FODMAP diet for healthy volunteers (181 +/- 77 ppm.14 h vs 43 +/- 18; mean +/- SD P < 0.0001) and patients with IBS (242 +/- 79 vs 62 +/- 23; P < 0.0001), who had higher levels during each dietary period than the controls (P < 0.05). Breath methane, produced by 10 subjects within each group, was reduced with the high FODMAP intake in healthy subjects (47 +/- 29 vs 109 +/- 77; P = 0.043), but was not different in patients with IBS (126 +/- 153 vs 86 +/- 72). Gastrointestinal symptoms and lethargy were significantly induced by the high FODMAP diet in patients with IBS, while only increased flatus production was reported by healthy volunteers.


CONCLUSIONS
Dietary FODMAPs induce prolonged hydrogen production in the intestine that is greater in IBS, influence the amount of methane produced, and induce gastrointestinal and systemic symptoms experienced by patients with IBS. The results offer mechanisms underlying the efficacy of the low FODMAP diet in IBS.
A Face in any Form: New Challenges and Opportunities for Face Recognition Technology

Despite new technologies that make face detection and recognition more sophisticated, long-recognized problems in security, privacy, and accuracy persist. Refining this technology and introducing it into new domains will require solving these problems through focused interdisciplinary efforts among developers, researchers, and policymakers.
Kinetics of carbon dioxide absorption into aqueous MDEA solutions

The CO2 absorption rate in aqueous methyldiethanolamine sol utions was measured using a stirred cell with a flat gas-liquid interface. The measurements were performed in the temperature range of (293.15 to 333.15) K and amine concentration range of (10 to 20) mass %. Measurements were based on a batch isothermal absorption of the gas. The kinetic experiments were conducted under pseudo-first-order regime. The cal cul ted initial absorption rates enabled to estimate the fo rward, second order reaction rate constant of CO 2 reaction with MDEA in aqueous solution.
Connected Roads of the Future: Use Cases, Requirements, and Design Considerations for Vehicle-to-Everything Communications

The ultimate goal of next-generation vehicle-toeverything (V2X) communication systems is enabling accident-free, cooperative automated driving that uses the available roadway efficiently. To achieve this goal, the communication system will need to enable a diverse set of use cases, each with a specific set of requirements. We discuss the main usecase categories, analyze their requirements, and compare them against the capabilities of currently available communication technologies. Based on the analysis, we identify a gap and indicate possible system designs for the fifth-generation (5G) V2X that could close the gap. Furthermore, we discuss an architecture of the 5G V2X radio access network (RAN) that incorporates diverse communication technologies, including current and cellular systems in centimeter wave (cm-wave) and millimeter wave (mm-wave), IEEE Standard 802.11p [1], and vehicular visible light communications (VVLC). Finally, we discuss the role of future 5G V2X systems in enabling more efficient vehicular transportation: from improved traffic flow and reduced intervehicle spacing on highways to coordinated intersections in cities (the cheapest way to increasing the road capacity) to automated smart parking (no more visits to the parking garage!), all of which will ultimately enable seamless end-to-end personal mobility.
Impact of a fall prevention programme in acute hospital settings in Singapore.

INTRODUCTION
This study aimed to develop a multifaceted strategy using tailored interventions to implement a fall prevention programme, and to achieve a change in fall prevention practices and a reduction in fall incidence at an acute care hospital in Singapore.


METHODS
A comparative study was conducted at two acute care hospitals (intervention and control) in Singapore. Pre-intervention, post-intervention and six-month follow-up knowledge assessments of 641 nursing staff, and audits of fall rates and fall prevention practices were performed to determine the effectiveness of a multifaceted strategy with targeted interventions in supporting the implementation of a fall prevention programme.


RESULTS
The mean post-knowledge test scores at six months were statistically significantly higher (t[516] is -3.3, p-value is less than 0.01) at the intervention hospital (10.3 +/- 2.3) compared to the scores at the control hospital (9.8 +/- 1.8). Increased compliance with the use of fall risk assessment tools was evident in 99.4 percent and 99.3 percent of all patient records at the control and intervention hospitals, respectively. Following the implementation strategy for a fall prevention programme, there was a non-significant reduction in fall rates from 1.44 to 1.09 per 1,000 patient days at the intervention hospital. No reduction in the fall rate was observed at the control hospital.


CONCLUSION
A multifaceted strategy for the implementation of a fall prevention programme was effective in increasing nurses' knowledge and the use of the fall risk assessment, but did not have a statistically significant impact on a reduction in the fall rate. The increase in nurses' knowledge and change in nursing practice were important markers of success in terms of fall prevention at the acute hospitals.
Software clone detection: A systematic review

Context: Reusing software by means of copy and paste is a frequent activity in software development. The duplicated code is known as a software clone and the activity is known as code cloning. Software clones may lead to bug propagation and serious maintenance problems. Objective: This study reports an extensive systematic literature review of software clones in general and software clone detection in particular. Method: We used the standard systematic literature review method based on a comprehensive set of 213 articles from a total of 2039 articles published in 11 leading journals and 37 premier conferences and
